“My Oedipus Complex” by Frank O’Connor Essay

In the short story, My Oedipus Complex, Frank O’Connor writes of a young child who is forced to deal with issues of confusion and jealousy through a first person point of view. Through O’Connor’s elements of facetiousness and truth, he explains how such issues create a sort of ironic domins effect and, in this case can actually bring people closer together. In the beginning, the young boy displays signs of excitement and contentment when his father arrives unexpectedly on his visits from the war. His â€Å"pleasant musty smell† and â€Å"Santa Claus entrances and exits† intrigue him. As long as his daily routines are uninterrupted, he remains in a state of appeasement. The juvinile knows nothing of the problems the mother and father are facing. He is confined to a world all his own. If the point of view were changed in such a situation, then the father may tell of how naive and innocentthe child is or how oblivios he is to what a horrible condition they are faced with. The plot would change drastically. If the point of view were changed to the third person objective, or dramatic point of view, then the readers would assume their own emotion which would absolutely change the tone of this short story. Other elements such as theme could also be altered if this was seen in third person. The child’s feeling of hostility toward his father could only be seen through this example first person point of view.

The Variety Of Plastic Wastes Plastics Environmental Sciences Essay

1. IntroductionRecycling of plastic discards is one method of cut downing municipal solid waste. They are get downing to fall in glass, steel, aluminium and paper as waste watercourse constituents that have been accepted into recycling plans across the state. It is hard, nevertheless, to spread out post-consumer plastics recycling beyond the easy recognized milk jugs and sodium carbonate bottles for proficient, economic and societal grounds: The assortment of plastic wastes Plastics in municipal solid waste are a really heterogenous aggregation of stuffs that encompass non merely a wide scope of types made from a individual rosin, but besides an increasing figure of points that include a blend of rosins, either automatically or chemically bonded together. The assortments are made to boot diverse through the usage of plastic additives to give specific merchandise qualities. The trouble of screening plastic rosins It is technically hard to obtain comparatively pure rosins from assorted plastics collected for recycling. Commercially demonstrated separation engineerings are about entirely limited to procedures that separate polyethylene terephthalate ( PET ) and high denseness polythene ( HDPE ) . Low denseness of post-consumer plastics wastes Plastics occupy a high volume/weight ratio compared to other reclaimable components in MSW, and this adversely affects the practicality and economic sciences of plastics aggregation in a recycling plan. Landfill recreation rates are measured on a weight footing and the weight urban sprawl of plastics to MSW is comparatively little ( even though the landfill volume occupied by plastics is big ) . The big volume occupied by plastics in a recycling truck can displace the ability to roll up other â€Å" heavier † recyclables. Limited history of plastics recycling for many plastics recycling options. Merely limited informations exist from which to generalize costs, engagement rates, technological or institutional barriers, and other factors which affect long-run viability. However, in order to spread out the recovery and recycling of plastics and diminish the sum of waste disposed in landfills, it will be necessary to get the better of these troubles. Because of its heterogenous nature and the sum of contaminations present separation of post-consumer assorted plastic waste is the most hard. Waste plastics from industrial operations are cleaner and more homogenous in rosin type and bit signifier than postconsumer plastics. The term â€Å" assorted plastics † has been used to depict wide graduated table processing of post-consumer plastic waste, although no formal definition yet exists. In its broadest sense, assorted plastics means a aggregation of a mixture of plastic rosins or a mixture of package/product types which may or may non be the same plastic type or colour class, and may non hold been fabricated utilizing the same fabrication techniques. While it is possible to market recycled assorted plastic waste with limited separation, greater value and broader applications are achieved with homogenous rosins. Although it is possible to blend different types of polymers together, the ensuing physical belongingss are less desirable than those of the original constituents. General schemes for the separation of assorted plastics ( and hence schemes for increased recycling of plastics ) , with their several advantages and disadvantages are shown in Table below. Technological research sing big scale separation of assorted fictile waste watercourses is being conducted, but some of it is far from commercial application. Governmental ordinances sing standardisation for merchandise applications and sortation would most probably non hold widespread credence. The staying two attacks, â€Å" Manual separation by consumer or aggregation bureau † and â€Å" Collection focused on specific rosin or container type, † are presently in usage. They are limited due to the cost of manual labour and a more narrowly defined plastic type, but have the potency for application to wider scopes of plastics than is presently collected by most recycling plans. The intent of this study is to place methods used for plastics aggregation, fictile aggregation composings and coevals rates, plan costs, processing and terminal market usage of assorted plastics in recycling.Advantages and Disadvantages of Alternative Strategies to Allow Separation ofResin Types from Mixed Recyclable PlasticsScheme Advantages Disadvantages Separation after compression or tear uping Convenience to consumers ; does non necessitate consumers to divide wastes Minimizes sorting, storage and transit demands for roll uping bureaus Allows aggregation schemes capturing big volume and Presently non possible to divide into homogenous rosins after tear uping Shreding outputs assorted plastics non conformable to treating into merchandises displacing virgin rosins Container labeling and automated separation Convenience to consumers ; does non necessitate consumers separate wastes Promises to let separation into homogenous watercourses Minimizes work force demands required for screening Technology non presently in topographic point May necessitate a centralised storage and separation installation with associated costs Manual separation by consumer or aggregation bureau Simple engineering Convenience to consumers if roll uping bureau performs separation Allows aggregation schemes capturing big volumes of MSW plastics Potentially prohibitory work force demands May necessitate big storage and transit installations Inconvenience to consumers if they are required to execute separationPlastics in Municipal Solid WasteRecycling of the plastics has the potency for cut downing the waste watercourse and widening the life of landfills. Currently plastics make up an estimated 9 % by weight and 20 % by volume of landfill discards [ U.S. EPA, 1990b ] , and most of it ( 83 % ) is the six thermoplastics. The wide designation of disposal paths and types of plastic disposed in MSW landfills on a national footing has been performed by Franklin Associates in a survey for the Council for Solid Waste Solutions ( CSWS ) , a plan of SPI, which is supported by major petrochemical and, polymer production companies. The survey examined the disposal paths of the 15 largest rosins produced harmonizing to 1988 gross revenues and identified which were disposed in MSW and which were. non disposed in MSW. Non MSW disposed wastes included industrial waste, building and destruction dust, sludge and incinerator residues. There is a deficiency of documented information sing disposal paths of specific plastics and therefore a significant part of the research was based on communicating with industry makers and rosin manufacturers. The information show that for the most portion disposal of specific rosins is via either MSW or non-MSW methods of disposal ( instead than both ) and that PVC is the lone rosin o f the taking six that is non disposed preponderantly through MSW. Overall, the analysis shows that 61 % of plastics are disposed in the MSW watercourse and 39 % in the non-MSW watercourse. Residences were identified as the primary beginning of plastics in the MSW watercourse, consisting 60 % of the plastics disposed, followed by the commercial sector lending 25 % and the institutional sector lending 15 % . The finding as to what plastic merchandises could be apportioned to the three classs of residential, commercial and institutional waste was based on market gross revenues information, grouping of merchandise types, and premises on the pan of the undertaking squad as to where terminal usage of the fictile merchandise would probably happen.Plastics Recycling TechnologyWhile there is overlap among the above classs, the list progressively includes more plastic/product types from top to bottom. Near the underside of the list, the demand to place specific plastic by merchandise type bec omes less necessary. Some recycling proms which are in the center of the above list ( e.g. detergent and bleach bottle class, all fictile bottle classs ) have lengthy designation /instruction sheets for the householder in order to prevent aggregation of specific containers which are non blow molded or which contain hard to clean merchandises such as oil containers. The drawn-out direction demands can take to non-participation because of householder attempt and confusion. Confusion tins besides Load to participants lodging all plastics ‘gust to play it safe. † A less confusing attack would be to roll up all It1 and # 2 bottles, all plastic bottles, or all RIG, since it has been shown that even a narrowly drained fictile watercourse ( such as fictile drink bottles ) consequences in a important part ( & gt ; O % ) of the plastic deposited non being what was asked for.Word picture, Generation and Collection of PlasticsWhen sing plastics for inclusion in a recycling plan, the inquiries of â€Å" How much plastic is in MSW? † and â€Å" How much plastic has been captured in bing recycling plans? † semen to mind. These inquiries are even more prevailing when assorted plastics aggregation is being contemplated. As may be expected, there are few recycling plans which presently collect more than HDPE bottles and PET bottles, and there are even fewer that collect movie plastic in add-on to rigid fictile containers. While coevals rates have been developed for milk jugs and sodium carbonate bottles based on aggregation informations, there is small aggregation informations for extra plastics. This subdivision of the research attempts to supply word picture and coevals informations from surveies and plans affecting multiple plastics. Many of the municipalities discussed in this chapter were either participants in pilot assorted plastics recycling surveies or received public support to carry on research on an facet of curbside recycling aggregation. The informations shown can be used in initial planning for gauging measures involved in plastics recycling aggregation and for gauging non-specified plastic and non-plastic contaminations. They can besides be compared to the experiences of other municipalities which have conducted signifiers of assorted plastics recycling. It should be noted that while fictile coevals and composing informations are presented from national and local surveies, it does non replace the demand for such an attempt in a community ‘s solid waste appraisal.Assorted Plastics in Recycling ProgramsWhile per centum of plastics in the waste watercourse has been studied in a figure of locations, less information is available on the type of plastics collected in recycling plans bespeaking assort ed plastics. Each recycling plan is alone in its word picture. Most fictile curbside aggregation is commingled with other recyclables and sorted at a MRF. Curbside aggregation across the state has merely late started to include fictile containers, and even so most aggregations are PET and HDPE drink bottles.Plastics Recycling ProgramsCurbside recycling is turning at a enormous rate. In 1989, it was estimated that 9 million U.S. families were portion of curbside recycling plans and that 20 % collected some type of plastic. In 1990, approximately 40 million people ( approximately 14 million families ) were participants in curbside recycling [ Glenn, 19901. By 1992, 20 % of all U.S. families ( 16 million families ) are expected to hold curbside recycling and 180-330 million lbs of plastic will be recycled yearly [ COPPE ] .Curbside Collection of Plastics in IllinoisAs of August 1990, about 110 municipalities conducted curbside aggregation of recyclables in Illinois. It is estimated tha t 600,000 families will be served by curbside recycling by the terminal of 1990 [ Feamcombe, 19901. A reappraisal of these municipalities indicates 43 collect some type of post-consumer plastic impacting a sum of 221,000 abodes. This represents a dramatic addition since 1987, when merely a few communities collected plastics. Curbside plastic recycling engagement in Illinois can be one of three types: plans which collect a signifier of assorted plastic, those which collect merely PET and natural HDPE drink bottles, and those which collect merely natural HDPE bottles. Approximately 22 municipalities ( 87,500 abodes ) collect a signifier of assorted plastics, 5 municipalities ( 27,600 abodes ) collect PET and natural HDPE drink bottles and 16 municipalities ( 106,100 abodes ) collect natural HDPE bottles. The assorted plastics curbside aggregators, for the most portion, collect blow molded colored and natural HDPE and PET bottles. The â€Å" Plastics Collected † efforts to describe every bit accurately as possible the plastics requested of occupants. The Naperville Area Recycling Center ( NARC ) is the widest ranging assorted plastic recycling plan ; to boot roll uping PS and LDPE 6- battalion rings as portion of trial plans for Amoco and Illinois Tool Works, severally.Film /Rigid Plastics RecyclingA figure of countries, particularly on the E seashore, am now roll uping RPCs. Some are pilot plans in trial countries and others are to the full implemented. Large fictile processors such as Wellman ( Allentown, PA ) , Waste Management ( Oak Brook, IL ) , Day Products ( Bridgeport, NJ ) and Union Carbide ( Pistacaway, NJ ) are be aftering big graduated table RPC curbside aggregation and processing in the following few old ages. The most locally noteworthy plans are the Chicago Park District Plastics-on-Parks slump plan which accepts RPCs, and the curbside aggregation of stiff plastics in Akron, Ohio. A few r ecycling plans are roll uping any rigid/film plastic. Most of these are located in close propinquity to a fictile timber maker which accepts assorted plastic movie or commingled bales. This includes communities around Toronto, Ontario, on Long Island, New York, in cardinal Michigan and in northwesterly Iowa. Milwaukee, Wisconsin started roll uping any type of plastic with an SPI l-7 label in August, 1990 from a 5,147 abode pilot country and has expanded since. The metropolis besides collects HDPE milk bottles and other recyclables from 40,000 extra families as portion of its established curbside recycling plan. Waste fictile part from the pilot country has been swung The metropolis uses semi-automated side lading trucks with partial commingled aggregation. Newspaper, composition board and magazines are emptied into a bin offprint from other recyclables. Material is sorted out on a conveyer belt at a MRF with manual picking Stationss. HDPE, PET and PVC are picked out and baled and the staying plastics are baled commingled. Per capita coevals and the cost of adding assorted plastic aggregation have non been estimated. There have been pilot RPCXilm aggregation plans with hapless consequences due to extended ( wasteful ) screening necessary at a stuffs recovery installation ( MRF ) to fix stuff for market and due to nutrient taint. One such plan, conducted in the Portland metropolitan country in 1990, had high sums of nutrient and residue taint which resulted in the landfilling of big sums of movie and containers. There was besides a big cull rate ( 30 % ) due to unacceptable stuffs, e.g. gum elastic hosieries, family medical waste. Consumers reported trouble in holding to believe it was necessary to screen out all plastics at a MRF to obtain any market monetary value. Resident instruction as a cardinal component, including cleansing and proper readying of reclaimable plastic, was stressed multiple times as a solution to deciding the job. Although occupants were asked to alter forms in update mailings, participants from the beginning of the plan did small to alter their forms. The sortation company take parting in the pilot indicated that the types of plastic to be collected should hold been more limited. A six month pilot aggregation of assorted plastics was conducted on 4,500 families between November, 1989 and April, 1989, in Seattle, Washington. The plan, which included aggregation of movie and plastic negligees in add-on to more normally, collected plastics, allowed the following plastics to be disposed in curbside aggregation as described by the Mailer to participant householders:ContainersPop and H2O bottles Milk and juice jugs Dishwashing soap bottlesPlastic bagsGrocery store bags ( produce & amp ; check-out procedure sort ) Food bags ( staff of life, Zea mays everta, cereal, etc. ) Rubbish can linersRecycling CostssIt is hard to turn to the cost of fictile aggregation and processing without including other recyclables as good. How efficaciously plastics can be added to a recycling plan depends on the current aggregation system and the flexibleness of it. It is necessary to measure these issues in order to place the best method for run intoing recycling ends and for supplying an indicant of capital and operating budget outgos. Because there are big fluctuations between degrees of recycling, it is about ever necessary to analyze recycling plan costs on a individual footing. Presented in this chapter is a cost estimation of curbside recycling options for the City of Madison, Wisconsin and an estimation of the cost of & A ; & A ; g differing degrees of plastics aggregation to bing curbside aggregation plans in the Minneapolis/St. Paul, Minnesota country. Each is of import because they examine a figure of options, thereby supplying a scope of values based on the options, and because their estimations include the use of bing equipment, the demand for capital purchases is minimized. Besides presented are costs which may be expected for treating plastics ( baling, screening, crunching ) at a material recovery installation, and computing machine methods for gauging and optimising recycling costs.Recycling Program VariablesBecause curbside pickup achieves the highest recovery rates, cost effectivity of recycling was evaluated utilizing curbside aggregation. The undermentioned variables affect curbside or slump aggregation costs: Recyclables collected Method of screening ( curbside versus MRP ) Families in the service country Household engagement rate Collection period set out rate Collection frequence Part of recyclables separated by the householder for recycling ( termed gaining control rate ) Generation per individual or family Travel clip between families Time required per halt Travel clip to dump Time at the processing centre Cost of forces and equipment Forces per truck Market monetary values of recyclables Cost to process/Level of marketability Transporting cost Cost turning away of landfill recreation4.2 Recycling CostssAlthough there is a societal desire to recycle, the current monetary value of landfill infinite in some countries has non yet offset the cost of curbside aggregation of recyclables. Recycling in Illinois is by and large paid for on a per family footing. The cost of recycling may be expected to add lO-25 % to the cost of bing garbage disposal. This translates into an extra cost of $ l- $ 2.50 per month per family, either paid by a municipality through, general/taxpayer financess or straight included on householder measures.4.3 Collection TimessThe clip it takes to roll up recyclables has a direct impact on the economic sciences of curbside aggregation. Discussed below are some field measurings of aggregation times utilizing changing aggregation methods. Assuming aggregation methods are similar, the aggregation times shown can be used for measuring curbside aggregation of plastics and curbside recycling in general. The Madison, Wisconsin pilot, which collected recyclables commingled in clear plastic bags, recorded the aggregation melodies. The mean aggregation clip for all four aggregation trucks utilized is about 1 minute per halt. This does non include dumping clip, break clip, and other clip spent non related to aggregation, but does include clip driving to and from the aggregation paths. No separation of stuffs was performed at curbside. 4.4 Recycling Truck Costs and Truck Collection Method for Plastics Collection vehicles are frequently the largest capital disbursal associated with curbside recycling. There are three general manners available for recycling: unfastened top trucks, closed organic structure trucks and dawdlers. Dawdlers, which contain bins that may be individual, segmented or removable, arc normally chosen for recycling, Depending on the application, there may be disadvantages with a dawdler due to manoeuvrability or capacity. Open top trucks have an unfastened top and are typically loaded through a series of doors along the side of the truck, which can skid up as a compartment fills. Closed organic structure trucks have an enclosed, partitioned aggregation container and are loaded from the side or top through an gap. Closed organic structure trucks are besides manufactured with semi-automated burden devices, such as a trough along the side of the vehicle, which can be emptied hydraulicly into the top of the vehicle container. Appendix A provides a listing of the makers of recycling vehicles and recycling dawdlers. Dawdlers are by far the lowest cost aggregation option. Their expected base cost ranges from $ 12,000 for a 15 yd3 dawdler to $ 18.000 for a 22 yd3 dawdler. The basal monetary value of an unfastened top truck will run from $ 25,000 to $ 70,000, with an mean monetary value of around $ 45,000/truck. Open top trucks have capacities of 15 to 25 yd3. The monetary value of a closed organic structure truck ranges from $ 50,000 to $ 80,000, and semi-automated closed organic structure trucks cost $ 70,000 to $ 90,000. Closed organic structure trucks are the largest and have capacities of 20 to 35 yd3. Monetary values of specific truck types are reviewed in Bio rhythm, 1989. The undermentioned comparative truck volumes have been estimated by the Center for Plastics Recycling Research for aggregation of recyclables: old newspaper, 23.2 % ; glass bottles, 13.0 % ; steel tins, 10.7 % ; aluminium tins, 16 % ; PET drink bottles, 17.6 % ; and HDPE milk, H2O bottles, 19.0 % . A recycle composing survey with per family coevals and denseness transition will assist a vicinity determine the volumes to anticipate. It is estimated that aggregation of uncrushed plastic HDPE and PET drink bottles can busy 37 % of a aggregation trucks volume while merely lending to 5 % by weight of the load_ If aggregation of plastic fills recycling truck bins and consequences in modifying a aggregation path to unclutter the burden prior to the filling of other truck bins ( such as old newspaper ) , the cost of fictile aggregation can lift significantly. Simple solutions have been suggested: Add a coop on the top or dorsum of the truck to keep plastics. Use gauze or a bag on the side of the aggregation vehicle to keep plastics. Collect plastics in transportable bags which can be removed and replaced with empty bags when full. Put plastics in an fresh part of the aggregation vehicle. Add or modify the aggregation vehicle to include compression. All but the last option requires curbside sorting of stuffs or at least the plastic from other recyclables. However, many curbside recycling plans use a commingled aggregation. Adding on-board compression is offered commercially but its effectivity is non good known. Problems with on-board compression are the extra cost of modifying an bing aggregation vehicle and the ensuing minimum net volume nest eggs after add-on of the compactor. The Council for Solid Waste Solutions is carry oning research on increasing compactor effectivity. The consequences should be available in 1991. One method of cut downing plastic volume is to educate consumers to oppress their plastic bottles prior to disposal. The National Association for Plastic Container Recovery, ( NAPCOR ) an industry trade group which promotes plastic recycling, provides extended media and get offing services to help communities in educating householders.4.5 Procedure CostManual separation of plastic bottles, the current most normally accepted method, is estimated to screen anyplace from 1 to 6 bottles per 2nd per sorter with a conveyer belt/manual choice station agreement. A 1 bottle/second choice velocity at an mean bottle weight of 0.14 – 0.15 pounds/bottle consequences in a procedure rate of 500-550 lbs per hr. At $ 10/hour labour, the kind cost is $ O.O2/lb. , non including operating expense, benefits, baling, crunching, or cargo. The general cost for plastic handling and processing has been estimated as follows [ PRC, 1990b ] : Screening 2-3eAb Baling 3-4eAb Crunching 3-4eAb. Cleaning ( flake Input/output ) 10 – 15 e/lb. Pelletizing 5 – 7 e/lb. As an illustration of the overall sorting costs, Somerset County, NJ, which has compulsory recycling of any fictile bottles and manual sortation at its MRF, processed about 8,000 lb./day of plastic bottles in 1990. When the stuff is brought into the MRP, a negative kind is performed on the stuff to take all non-bottle points and bottles that are non marketable. The terminal consequence is a mixture of PET, HDPE clear and colored, and PVC bottles which are marketed in a baled commingled province. The county receives $ O.O3/lb. for the commingled bales. The operation utilizes county employees at an mean rate of $ 7SO/hour along with a work item from the county gaol. Daily work force costs are $ 660, with overhead being another $ 200, for a entire day-to-day cost to run the plastic operation estimated at $ 86O/day. After gross, the cost is reduced to $ 62O/day [ Laze, 19901. This puts the approximative overall kind and baling cost at11 e/lb. , non including gross. The Rutgers Center for Plastics Recycling Research has likewise estimated fictile bottle sorting and baling costs 12 e/lb.Waste programThe Illinois Department of Energy and Natural Resources ( IDENR ) besides make available a computerized incorporate solid waste direction planning theoretical account called WASTEPLAN ( developed by Tellus Institute of Boston, MA ) . The plan addresses composting, recycling, incineration and landfilling options. Plastics can be included in the recycling part of the theoretical account. It has a bill of fare driven construction and allows for fluctuation of a assortment of input informations including waste watercourse definition, solid waste coevals, reclaimable stuff, aggregation systems, and processing and disposal installations. It besides is equipped with a default informations tile to let for acquisition and customization. IDENR correspondence should be addressed to the Office of Solid Waste and Renewable Resources, 325 W. Adams Street, Springfie ld, IL 62704, ( 800 ) 252-8955.Least-Cost SchedulingA least cost programming of recycling has been proposed by Lund [ 1990a, 1990bl. Linear scheduling can be used to minimise the present and future costs of recycling, landfilling and waste disposal. It allows the user to turn to the limited capacity of an bing landfill. The method can besides be used to measure the recycling determinations of waste aggregators which do non greatly affect the life-time of a landfill operated by another entity. The theoretical account histories for the undermentioned variables: recycling option costs, closing costs, building costs of future waste disposal installations, grosss from recyclables, hereafter landfill life, family coevals rates and market monetary values. Estimates for these variables must be made anterior to come ining the plan. The method does non include indirect costs such as environmental impacts ( e.g. , aquifer taint ) . However, direct costs related to environmental impacts, such as insurance coverage, may be included. Example Costss of Including Recyclables in a Curbside Collection Program [ Cornell, 19901 An illustration which includes the costs associated with landfill closing and replacing landfill building may be used to exemplify this method. A little metropolis ( 10,000 families ) wants to implement recycling to postpone landfill closing and future replacing costs of waste disposal installations. Three options are considered: Option 1 Recycling of family waste paper ( old newspaper and debris mail ) and old corrugated composition board ( CCC ) with hebdomadal aggregation of the separated stuff by a recycling vehicle. Estimated recovery rate is 70 % of the waste paper and 50 % of the OCC. Option 2 Recycling of glass, steel tins, ferric and aluminium in add-on to the family waste paper from option 1. The recovery rates are 75 % , 70 % . 70 % and 70 % , severally. Option 2 requires a larger truck traveling more easy than the option 1 truck. Option 3 Collection and composting of yard waste. The estimated recovery rate is 90 % of all yard waste and 30 % of soil disposed ( much of the soil comes from yard waste ) . The cost and landfill effectivity of each recycling option, since option 2 requires merely a larger truck on paths used for option 1 ; the cost of option 2 is merely the incremental cost of running trucks slower to pick up, procedure and market the extra stuff. Without recycling, the landfill would be filled and closed in 11 old ages. If all recycling options were implemented for all families, there would be a 65 % volume decrease in the rate of waste disposal in the landfill, and landfill life would be extended another 13 old ages to twelvemonth 24. The present value of cost and nest eggs calculated at each twelvemonth of projected landfill closing beyond the initial lower limit of 11 old ages. The least cost option would give a landfill life-time of 21 old ages. This is 10 old ages greater than if no recycling option were implemented, but three old ages shorter than if all recycling options were implemented on all families at all times.Markets and Packaging Changes forRecycled Plastics5.1 Recycled Resin DemandThe demand for recycled rosins is expected to raise significantly in the following three old ages, harmonizing to the survey, â€Å" The Market for Plastics Recycling and Degradable Plastics, † by Find/SVP, a New York market research house. HDPE and PET are estimated to consist 65 % of the recycled rosin market for 1990. It is expected that the sum of recycled HDPE and LDPE will about double between 1990 and 1991, from 252 to 498 million lbs, and from 87 to 163 million lbs, severally [ Charnas, 19901. It is estimated the HDPE recycle will transcend 1 billion lbs by 1994. Figure 5.1 shows the recycled rosin demand for the six primary thermoplastics by type from 1988 to 1993. The combined sum of recycled rosin for the six plastics by the terminal of 1993 is projected to be 3.5 times the 1990 degrees. U.S. Demand of Recycled Resin, by Type, from 1988 to 1993 ( Charnas, 19901 ) Recycled rosin monetary values for assorted phases of processing are shown below. The pricing information is derived from a hebdomadal plastics publication pricing chart during in-between 1990 and interviews with recyclers, rosin agents and bargainers. In the long term, the monetary value of recycled rosin floats relative to virgin rosin monetary values. A common monetary value for a baled mixture of clear and colored HDPE bottles and PET bottles which have been cleaned of foreign stuff is 2-4 cents per lb. Monetary values for off-specification, cleaned postconsumer clear HDPE m are at 60-70 % of virgin rosin monetary values. Cleaned, postconsumer clear HDPE Q & A ; J now float at 50 % of virgin rosin monetary values [ PRC, 1990bl. It is believed that the monetary value of recycled rosin will near that of virgin rosin in the close hereafter due to the demand from big users such as the Coca-Cola Company, Procter & A ; Gamble and Lever Brothers. The consequence of colored recycled rosin on monetary value can be seen in table below. While clean green regrind PET is selling at 17 $ /Ib. , clear is selling for twice every bit much. Overall, the two major recycled rosins, PET and HDPE, continue to keep or appreciate in value against the same virgin rosin, and are expected to lift in the hereafter. While the monetary value of virgin HDPE declined in 1990, the monetary values for clean HDPE regrind has remained comparatively changeless in the scope of 22-30c/lb. The monetary value for recycled PET increased during 1989 and 1990, and monetary values for PS and PVC remained changeless. The monetary values for clean regrind are by and large about half that of virgin stuff. LDPE, LLDPE and PS are expected to increase in value Oklahoman than other plastics chiefly because major plastics providers are involved in change overing polythene and PS waste into reclaimable stuff.Packaging Changes 10 Increase Recycle RatessPlastic is frequentl y non included in recycling because the costs of aggregation and processing do non countervail the grosss gained. A push in plastic recycling today is to diminish the post-use processing necessary to accomplish detached rosins for reuse. The cost to treat rosins with acceptable degrees of foreign plastic and non-plastic contaminations may merely be marginally less than the value of the processed rosin. It is desirable for gathered plastics to be separated from each other so there is greater value in the stuff and broader application potency. As a effect, alteration of fictile packaging design methods is necessary to obtain a higher value merchandise for recycling following consumer/industry usage. Guidelines for boxing design to minimise its part to the solid waste watercourse and add more plastics to the recycle watercourse have been proposed [ Selke, 19901:Use reclaimable bundlesIf a bundle can be reused in its original application, it can be really effectual at waste decrease by extinguishing disposal demands for several rhythms. Obviously other considerations must come in into this determination. If the bundle is non returned, it can non be reused, so the cooperation of the user is important. This option is likely much easier to implement for distribution bundles than for consumer 1s. Costss and energy demands of returning and cleaning containers must besides be analyzed. In many instances, containers will hold to be stronger to allow reuse and hence will utilize more stuff. The net benefits must be carefully calculated.Use a individual stuff, wherever possibleMultilateral bundles are, in general, less suited to recycling than individual stuff bundles. All fictile containers are preferred to plastic with paper and/or aluminium. Single rosin plastic containers are preferred to multi-resin plastic containers.Use stuffs that are either easy dissociable or compatibleIf a individual stuff can non be used If a many-sided construction is needed, the end is to pla n that construction in a manner that does the least harm to recycling possible for that bundle. The HDPE base cup on a PET drink bottle is non a serious job for recycling because a comparatively simple H2O floatation procedure will divide lighter than H2O HDPE from heavier than H2O PET.Use recycled stuffs where possibleThe being of markets for recycled stuffs is a cardinal portion of any recycling operation. It does no good whatsoever to divide and procedure stuffs if they do non happen utilizations in new merchandises. The packaging industry has an duty to increase its usage of recycled stuffs. While there evidently are applications for which merely virgin stuffs are suited, they should non be specified unless valid grounds for the exclusion of recycled stuffs exist. Writing specifications based on public presentation instead than material content may help in avoiding the unneeded exclusion of recycled stuffs.Eliminate toxic componentsBoxing designs should integrate merely nonhazar dous stuffs whenever possible. In peculiar, heavy metals used in additives, colorants and inks should be eliminated. If a company can non accomplish the coveted colour without heavy metals, possibly a alteration in colour coupled with a promotion run to allow the populace know the ground for the alteration could really greatly enhance gross revenues. Alteration of plastic packaging utilizing the above methods has the potency for increasing the measures of plastics recycled and bettering the economic sciences of the recovery procedure. Plastic bottle recycling can function as one illustration for exemplifying the possible benefits. A municipality with a recycling plan may work with local plastic bottle manufacturers to better bottle design so that after aggregation, plastic bottles could be sent straight to stop users without expensive processing, and more desirable rosin stuffs such as PET and HDPE would be used. Design criteria similar to the above guidelines have been submitted to back up such an attempt in fictile bottle production [ Anderson and Brachman, 19901: Bottle merchandises in clear instead than colored rosins ( with the colour on the label if necessary ) Do non utilize adhesives on the labels ( usage psychiatrist wrap, for illustration ) or utilize easy soluble adhesives Use non-aluminum caps made from the same rosin and with the same viscousness as the bottle organic structure Provide easy recognized labeling of plastic type Use industry supported runs to educate the populace to flatten fictile containers The first three standards are ab initio capable to front end merchandise proving to guarantee safe packaging, while the staying two standards are tied into post-consumer usage. Part of the inducement in developing future consumer plastic packaging which has higher value due to uniform rosin composing is the processing which could be eliminated. This will accomplish the greatest value from the recycled plastic by leting a maker which uses recycled content rosin to straight buy waste plastics without the cost of an intermediate processor. This would besides let municipalities to short-circuit intermediate processors and travel straight to stop users. This procedure is conducted in some municipality/company agreements with the recycle of clear HDPE bottles which are frequently baled or reground by a recycling plan and sold straight to a maker which uses secondary plastics.Markets in Primary RecyclingPrimary recycling or the converting of otherwise waste plastic into merchandises similar to the original merchandise is by and large the most favorite signifier of recycling. It is desirable because it is non necessary to make a new market niche for a merchandise and because the demand for virgin rosins are reduced. The fictile fabrication industry regularly recovers waste â€Å" spare bit † generated in-house because it is convenient to make so, and because the scrap stuff is contaminant free and of a known composing. The packaging industry is traveling beyond in-house recycle of fictile bit by fabricating bottles incorporating a certain part of post-consumer plastic merchandises chiefly because of its market entreaty and recycling ends set at the federal, province, and local degrees. Plastic users have made a market for recycled plastic by modifying machinery for two and three bed bulge caputs. & A ; bulge is a method applied chiefly to HDPE and sandwiches a recycled plastic bed in between virgin rosins. It is used because it produces a unvarying visual aspect of bottle outsides and a market safe container.5.4 Markets in Secondary RecyclingSecondary recycling is the recycle of plastic rosins into new merchandises with less demanding physical and chemical features than the original application. Assorted plastics are applied most easy in the secondary recycling market because less separation of rosin types and less complicated production methods are necessary to accomplish a finished merchandise. The most readily recognized secondary plastic merchandise is â€Å" fictile timber † ( thick bulge molded slabs of rosin in which some types of rosins act as tillers ) . Fictile timber is used to do park benches, fencing stations, boat docks, resort area equipment a nd the similar. Examples of other value-added merchandises which can be made ( via secondary recycling ) include merchandises such as recycling containers, garbage containers, flower pots, nursery potting trays, traffic cones, velocity bumps, downspout splash blocks, etc. Rubbermaid is bring forthing a assortment of garbage containers incorporating 10-Z % HDPE rebind and office accoutrements and nutrient service trays incorporating M-50 % I ‘S regrind. Another company, Utility Plastics of Brooklyn, NY, is injection modeling traffic cones and barriers incorporating waste HDPE.1. IntroductionI.I Plastics in Municipal Solid WasteRecycling of plastic discards is one method of cut downing municipal solid waste. They are get downing to fall in glass, steel, aluminium and paper as waste watercourse constituents that have been accepted into recycling plans across the state. It is hard, nevertheless, to spread out plastics recycling because of the assortment of plastic wastes, the trouble of screening different types of plastics, the low denseness of post-consumer plastics wastes in comparing to other recyclables and the limited history of plastics recycling. Because of its heterogenous nature and the sum of contaminations present, separation of post-consumer assorted plastic waste is the most hard. Waste plastic from industrial operations are cleaner and more homogenous in rosin type and scrap signifier. The term â€Å" assorted plastics, † a mixture of fictile types or a mixture of package/product types which may or may non be the same plastic type or colour class, has been used to depict wide graduated table processing of post-consumer plastic waste. Assorted plastics besides include merchandises which may be the same rosin type but which have been fabricated utilizing differing fabrication techniques. While it is possible to market recycled assorted plastic waste with limited separation, greater value and broader applications are achieved with homogenous rosins. Although it is possible to blend different type polymers together, the ensuing physical belongingss are less desirable than the original constituents. Technological research sing big scale separation of assorted fictile waste watercourses is being conducted. The progresss in fictile separation engineering are discussed in this study. The 1989 domestic ingestion of all plastics totaled 53.5 billion lbs, with 11.2 billion lbs, or 83 % , being eight plastic types: low denseness polythene ( LDPE ) , polyvinyl chloride ( PVC ) , high denseness polythene ( HDPE ) , polypropene ( PP ) , and polystyrene ( PS ) , polyurethane ( PUR ) , phenolic, and polythene terephthalate ( PET ) [ Modern Plastics, 1990a ] . HDPE, LDPE, PP. PS, PVC and PET are thermoplastics, capable of being repeatedly softened by additions in temperature and hardened by lessenings in temperature. They are besides referred to as trade good rosins because they are produced in the largest volumes at the lowest cost and have common features among manufacturers. Consumption of these six thermoplastics is led by the packaging industry. Polyurethane can be formed as a thermoplastic or a thermoset. Thermosets are rosins which have undergone a chemical reaction taking to a comparatively infusible province that can non be reformed. Phenolic are another household of thermosetting rosins. Although slightly anon. with â€Å" rosin † and â€Å" polymer, † the term â€Å" plastic † refers to a rosin which includes additives for the intent of supplying a manufactured merchandise. â€Å" Resins † ( or polymers ) are the basic stuffs for plastic merchandises, and most frequently denote a polymerized stuff without consideration of specific additive. A survey of the 15 taking rosins based on 1988 production identified that 44 billion lbs were disposed of in some mode [ Franklin Associates, 19901. Of all rosin types produced, 29 billion lbs are disposed in the municipal solid waste ( MSW ) watercourse each merely 1.1 % of the waste fictile watercourse is recovered [ U.S. EPA, 1990a ] . The balance is disposed as incinerator residue, sludge, industrial, or construction/demolition waste. Plastics comprised 9.2 % by weight and 19.9 % by volume of stuff discarded in MSW [ U.S. EPA, 1990b ] . One specific plastic type, PET drink bottles, which have been targeted for recycling through curbside aggregation and container sedimentation statute law, has reached noteworthy recycle rates of 23 % in 1988 and 28 % ( 175 million lbs ) in 1989 [ Plastic News, 1990aJ. The increased cost of landfilling waste, the volume occupied by fain plastic merchandises, the value of the fictile waste stuff, every bit good as the authorization of 25 % recycling of solid waste set by the province of Illinois make the add-on of plastics to recycling plans a necessity. Increasing the recycle of fictile containers, movie, and packaging in general from the waste watercourse is a logical following measure in increasing recycle rates. Municipalities and metropoliss are get downing to roll up fictile bottles, any type of stiff plastic container, and in some instances fictile movies. Film is frequently the most prevailing constituent of plastic on a weight footing. Further development of procedure and separation engineerings is necessary for assorted plastics if widespread recycling of plastic bottles, containers and movie is to be increased. This study discusses engineerings which have been developed for the separation and processing of waste plastics.Industry of Plastic Lumber Using Mixed PlasticsThe industry of flow molded additive profiles, or fictile timber as it is normally referred to, has received a great trade of attending as a solution to utilizing assorted plastics because minimum separation of the assorted plastic is necessary to bring forth this type of merchandise. It is viewed as a method to use fictile containers and movies en masse which could non otherwise be collected in important measure to warra nt separation. Plastic timber is besides viewed as a method to use â€Å" shadowings, † the assorted plastics left after a recycle watercourse back-number ‘mined † of higher value HDPE and PET bottles. Shadowings may besides typically be the plastics collected by recycling that were non asked for. Although, from a polymer scientific discipline point of position, such a diverse combination of plastics is non considered to be readily capable of â€Å" intermixing † into a compatible merchandise, the mixture can easy be processed into big cross-section points that have important strength and public-service corporation. Although the industry of fictile timber from assorted plastics without separation ( theoretically ) has barge possible as a solution to assorted plastics in general, there are associated jobs. Depending on market monetary values and propinquity to the maker, it may be necessary to pay a maker to take the waste plastic ( there are no assorted plastic timber manufacturers in Illinois ) . The cost of transporting can hold a big impact on the recycling operation economic sciences. As a consequence, there are fictile lumber start-up companies in advancement in Illinois, and Amoco Chemical Company has provided support to the Center for Neighborhood Technology in Chicago to analyze and beg proposals for a assorted plastic recycling works in the Chicago country [ CNT, 19901. It may besides be necessary to divide plastics to obtain a coveted colour or visual aspect of the finished timber merchandise, or to achieve a merchandise with sensible quality criterions. While dark browns, inkinesss an d greies are possible with assorted plastic bales ; lighter colourss such as bluish, xanthous and light greies are non possible without utilizing separated clear and white HDPE/LDPE. A big proportion of LDPE, both granulated and molded, produces articles which ‘are really elastic. Similarly, a big proportion of PP will bring forth articles which are brickle. Consequently, intermixing of granulated stuff by fictile type may be of import depending on the merchandise to be manufactured. If separated with adequate quality control, the detached plastics will convey a better monetary value through some other market. The maker may necessitate that a municipality roll uping assorted plastics buy the merchandise following recycling.2.3 General Guidelines for Plastic Lumber ManufacturingThe Advance Recycling Technology ET-l machine handles a broad assortment of thermoplastics, although there are restrictions due to the procedure and specific rosin belongingss, as with the ace wood machi ne. The undermentioned guidelines for the most popular plastics have been submitted by the U.S. provider of the ET-l [ Mackzo, 19901: LDPE or LLDPE A good stuff for usage in the procedure. However, LDPE is comparatively soft and merchandises incorporating excessively much of it may be insufficiently stiff for some applications, peculiarly in thin subdivisions. It should be assorted with stiffer stuffs such as HDPE or PP. HDPE A good stuff for usage in the procedure. HDPE is stiff and its mixtures with LDPE give a scope of stiffness that covers most merchandise demands. Much of the HDPE on the market is copolymer stuff, but this is of no effect to the recycler because for recycling intents its public presentation is really similar to that of a photopolymer. PP A good stuff for usage in the procedure. It is comparatively stiff and its mixtures with LDPE cover most of the scope of stiffness demands. However, the usage of more than 30 % by weight photopolymer PP is non advised because it is brickle at low temperatures and hard to nail. Polyvinyl chloride When finely land and good homogenized PVC can be recycled on the ET- 1. It can be mixed with other thermoplastics up to 50 % by weight. Post-consumer plastic typically contains 5 % PVC or less. PS Up to 40 % by weight of this stuff can be mixed in. Impact grades add stamina to the mix. Non-impact PS ( crystal ) tends to do surface finish jobs. Expanded PS ( EPS ) should be avoided as froth because of its low majority denseness. Testing shows considerable strength betterments at 10 to 40 % degrees of dandyish EPS. ABS A good stuff for usage in the procedure. The ABS household of rosins combines rubbery and plastic belongingss and is highly tough. ABS plastics are non loosely available Nylon A broad assortment is presently on the market. The most common, nylon 6 and 6/6 can be an linear at UD to 10 % bv weight because they impart stiffness to an otherwise soft compound. Textile nylon bit is normally nylon 6 or h/6. Nylon 6 castings are suited. Nylonss 11 and 12 are even more suited, but by and large non available. PET Although its 500A °F thaw temperature is above the normal scope of the ET- 1, up to 15 % can be mixed in if finely land and carefully blended. PET drink bottles, with HDPE base cup, labels and aluminium caps have been run at l00 % , but the merchandise is brickle due to crystallisation caused by slow chilling of thick subdivisions and debasement of the polymer caused by wet content.Merchandises from Mired Plastic LumberPlastic timber, as may be expected, has limited applications and usage. It costs more than similar outdoor class products/lumber and is hence harder to sell, but offers superior opposition to debasement and enduring out-of-doorss. There is transit, industrial, marine and agricultural applications for fictile timber merchandises. Such merchandises are by and large non yet sold at a consumer degree. A figure of markets for fictile timber merchandises are tied to the activities of province and municipal bureaus. The undermentioned market places are estimated to hold the most possible: Marine – docks, piles, breakwaters Industry – palettes sold straight to stop users Local authorization – transportation/road related markets and barriers, recreational country furniture and piles Agriculture – bets, electric fencing stations and parturiencies sold straight by concerted Fencing contractors Public utilities – H2O, sewerage and telephone markers, underground overseas telegram screens Builder providers and garden baby's rooms – ‘do-it-yourself fence and betsEnhancement of Plastic Wood PropertiesThe Center for Plastics Recycling Research at Rutgers has examined utilizations for plastics shadowings ( leftovers from recycling after the primary components of clear HDPE bottles and PET bottles have been recovered ) . A significantly greater market exists for the above mentioned separated HDPE and PET drink bottles than in assorted signifier, and hence their recovery may do economic sense. The research workers in New Jersey besides have found that 20 % of the plastic collected can be tailings stuff. It was felt that PS could heighten the belongingss of lumber merchandise made from shadowings which were characterized as mostly polythene ( HDPE or LDPE ) . The add-on of dandyish reground PS to the mixture significantly improved the mechanical belongingss of the resulting merchandise. Mechanical belongings trial consequences of assorted add-ons of PS. It shows that add-on of 10 % by weight PS increased modulus of snap 60 % , output strength by 15 % and compressive strength by 2 % . A consecutive line tantrum of the information shows that compressive and output emphasis addition about 15 % and 20 % , severally, for each 10 % addition in PS up to 50 % by weight. Above 35 % PS, the modulus of snap decreased somewhat and appeared to level off around 220,000 pounds per square inch. A possible account for the important addition in belongingss of the basal stuff is that PS, which is a calendered polymer at room temperature, reinforces the mostly polyolefin matrix in a mode similar to that of fillers used in composite stuffs even though PS and polyolefin are by and large considered to be incompatible [ Nosker et al. , 19901. It provides warp burden belongingss similar to the southern xanthous pine which is the company ‘s primary wood rival. The trials were run on a standard 2Ãâ€"4 piece of timber. Unreinforced, unformed fictile timber has warp burden belongingss that are less than that of southern xanthous pine.Buyers and Specifications for Waste Plastics4.1 Buyers of Waste PlasticRecovered plastic can be marketed for reuse in a figure of ways: By straight covering with a company which uses waste plastic in fabrication By straight covering with a plastic processor which will purchase waste plastic and market the cleaned and decontaminated merchandise By naming the cured waste plastic in a waste exchange for selling By marketing the recovered waste plastic through a bit rosin agent Waste exchanges are typically sponsored by a province and supply a waste naming free of charge. The intent of such a service is to function as an information clearinghouse, directory and selling facilitator so that waste stuffs may be reused or reprocessed in some mode. This frequently includes fabricating byproduct, excess stuff, off specification stuff, industrial waste and risky waste. Such exchanges are one path to selling waste plastic. The waste exchange listing will typically include the waste merchandise or coveted merchandise, the primary component ( s ) , sum and frequence of coevals and the operation the stuff is a byproduct from, if applicable. Samples are by and large available upon petition. Because of the extended figure of beginnings and types of plastics in waste, waste exchanges should by and large be utilized Q & A ; after other selling methods ( e.g. , scrap rosin agents, fictile recycling companies ) have been tried. The Illinois Environmental Protection Agency a nd the Illinois State Chamber of Commerce sponsor an Illinois based waste exchange ( Industrial Material Exchange Service, 2200 Churchill Rd. , # 31, P.O. Box 19276, Springfield, IL, 62704-9276, phone ( 217 ) 782- 0450 ) . A rosin agent ( a company which buys/sells off-grade rosins, off-specification rosins, regrind, disused or excess virgin rosins ) or a fictile bit animal trainer ( a company which may crunch, clean, denseness, pelletize, squeeze out, manufacture or treat waste plastic in some manner ) is typically where fictile bit is marketed after being collected at station consumer, station commercial, or industrial bit degree. Cargos in truckload measures are typically preferable, but smaller tonss down to bales are normally accepted with an attach toing decrease in monetary value paid. Harmonizing to the 1990-91 Directory of U.S. & A ; Canadian Scrap Plastics Processors and Buyers, there are about 14 rosin agents or bit animal trainers in Illinois, with 11 in the Chicago metropolitan country, 2 in Joliet and 1 in Decatur. Five of the companies in metro Chicago are purely agents of fictile bit. There are 20 extra brokers/processors in provinces neighbouring Illinois: 8 in Wisconsin, 7 in Michigan , 2 in Iowa, 1 in Indiana, 1 in Kentucky and 1 in Missouri. The name, reference and contact names of each handler/broker in Illinois and adjacent provinces. The cross-listing addresses the undermentioned rosins: ABS, Acetyls, Acrylics, Engineering thermoplastics, HDPE, LDPE, Mixed thermoplastics, Nylons, PET, Polyolefin, PP ; PS and PVC. While a bulk of the brokers/handlers accept scrap plastic from makers and processors, non all accept post-consumer stuff. Extra information on markets for recycled plastics is available in the Illinois Recycled Materials Market Directory ( lLENR/RR-87/01 ) , and the attach toing update, available from the Illinois Department of Energy and Natural Resources, Office of Solid Waste and Renewable Resources, Springfield, Illinois.

Wassily Kandinsky and Surrealism Assignment Example | Topics and Well Written Essays - 500 words

Wassily Kandinsky and Surrealism - Assignment Example The paper "Wassily Kandinsky and Surrealism" explores the art of Wassily Kandinsky. Despite his interest in art, he pursued law and economics as suggested by his parents. As a well-educated man, he chose to pursue Art and experiment with his obsession for colors. This paper will discuss how Kandinsky developed a unique style and explored abstract art as well as highlight some of the artists that he influenced. Worth noting is the fact that the painting was a spiritual thing for Kandinsky and he intended to use it to convey different levels of human emotions. He sought to use abstract forms and colors to explore different cultures and physical boundaries. In his view, abstract art was of critical importance in the expression of inner necessity. Kandinsky associated musical sounds with the potential to evoke different emotions in listeners. Therefore, he wanted to develop an art that could trigger similar emotions to his audience. He wanted to develop object-free art that had a spiritu al connection and a direct allusion to different emotions. Worth noting is the fact that his ability to create object free paintings with a strong allusion to different human emotions defined his unique style. Kandinsky had his first experience of object-free art in an exhibition that he attended and developed a close in this form of art. Kandinsky worked closely with other artists, who influenced him in different ways. For example, one of his close friends was Paul Klee with whom he shared artistic ideas.

Introduction of ICT Industry Assignment Example | Topics and Well Written Essays - 750 words

Introduction of ICT Industry - Assignment Example 1). As such, it can be observed that the phenomenal growth of ICT especially the internet has dramatically revolutionised the business landscape across the whole globe (Cloete, 2001). The advent of the internet has resulted in a boom of e-business activities between individuals as well as other organisations. This is commonly referred to as e-commerce where a range of online business activities for products and services are carried out (Andam, 2003). ICT supports online business which has significantly gained prominence during the recent years. It can also be seen that there have been various global changes in the ICT industry. For instance, Andam (2003) posits to the effect that developments in the Internet and Web-based technologies have resulted in the narrowing of distinctions between traditional markets and the global electronic marketplace-such as business capital size. The â€Å"International Data Corp (IDC) estimates the value of global e-commerce in 2000 at US$350.38 billio n and was projected to climb to as high as US$3.14 trillion by 2004,† (Andam, 2003, p.6). This major change in the global ICT industry is mainly attributed to the fact that information and communication technology is used to enhance one’s business where computer mediated network is used. Governments and businesses across the globe are investing heavily in the ICT sector in order to keep pace with the global changes in this particular industry. New Brunswick’s ICT sector is mainly comprised of organizations that deal with information technology (IT) services and products, telecommunications and interactive digital media (New Brunswick Information & Communications Technology Sector Strategy 2012-2016, n.d). In terms of local changes in IT, it can be seen that growth has been spurred by the following factors: Strong consumer demand for applications for mobile devices, increased productivity, privacy, integration of supply chains, emergence of affordable broadband as well as rapid pace of technological change. These factors have contributed to the changes in the IT sector. The New â€Å"Brunswick’s ICT sector is regarded as a major contributor to the economy, directly employing approximately 8,000 people and generating close to $875 million in Gross Domestic Product (2002$), close to four per cent of the provincial total in 2011,† (New Brunswick Information & Communications Technology Sector Strategy 2012-2016, n.d). The major changes that have been witnessed in this sector are related to its growth. It is expected that the industry grew at an average rate of two per cent since 2006, compared to the average of 1.3 per cent for all sectors. This shows that there have been major strides in the development of this particular industry compared to other industries in the province. The other major notable change is that it offers 100% broadband coverage which is by far a larger development compared to other regions across the whole glob e. With regards to investment, it can be seen that the province has also made efforts to attract investors to develop in this very important sector in as far as business development and growth are concerned. For instance, quite a number of marquee companies in the ICT sector have established operations in the province according to the New Brunswick Information & Communications Technology Sector Strategy 2012-2016.This development has helped the province to increase its visibility as a

Designing a network for a client Research Paper

Designing a network for a client - Research Paper Example The other challenge facing network security is hacking, which can be done from different sources. Most hacking is from the internet, where hackers target a particular network. A well-protected network should restrict access from outside since a computer from the outside cannot access a network infrastructure directly from outside. A proper design should cater for security measures to eliminate masquerading. A new design, for this reason, has to be introduced, which has additional features to enhance security (Wong & Yeung, 2009). Techniques such as NAT (Network Address Translation) should be used to deny access to the computers of a network from a remote computer. This makes it extremely hard to hack a network infrastructure from outside. The network infrastructure is at risk if one of its devices is compromised. Hacking from a device of the network infrastructure is much dangerous since passwords or authentication information about the network can be obtained with much ease. For instance, when a router is compromised, routing decisions can be influenced, and packet misrouting attacks can be launched easily from the compromised router. Hacking from a source close to the network infrastructure is extremely dangerous. Security measures such as installation of firewalls should be considered. Firewalls are installed to the boundary to protect the inside of a network (Wong & Yeung, 2009). A flat network design is much vulnerable to masquerading. In a flat network design, all the network infrastructure devices and end computers are connected together and do not have a clear boundary. This means when one computer is compromised, all the network infrastructure can be accessed by an attacker. When an end computer is attacked, all kinds of attacks can be launched on the network infrastructure the attacks include HSRP (Hot Standby Router Protocol), STP (Spanning Tree Protocol), and DHCP(Dynamic Host Configuration

Describe what you have learned from your experience as a member of a Essay

Describe what you have learned from your experience as a member of a team whose project was not completed successfully - Essay Example Compared to my previous successes, my first project is marked with a failure that I will never forget. On March of 2004, I have been given the privilege for an internship with XYZ Company in their Analytical laboratory. During my first day of work, I am quite challenged and enthusiastic to find that I will be working with two other new interns. Also, there will be no full time analytical chemists to assist us except my supervisor. These circumstances made me realize that my duties are going to be very challenging as well as interesting. Being able to prove our commitment, dedication, and skill, our group has been offered to work on a project, which would be very tedious for us as interns due to our lack of experience. However, we consider the task as a huge opportunity to further improve our skills and further our competencies. Because the current method is time consuming, tedious and requires continuous attention due to the usage of hazardous chemicals our project is to create a short method to analyze an element in one of the raw materials by using modern instrumentation. The group merrily took the project, albeit the very tight time constraint. We only have few more weeks for final exams and we are required to invest more effort to meet the short deadline. After a short discussion with the group, everyone agreed to contribute the best of his ability to accomplish the project within the allotted time. Two weeks later, my team and I have come to realize that we will not be able to finish the project on time, since we were working two days a week. The month passed and the shortage of time coupled with our lack of experience makes it impossible for us to complete the project. Pressing further, we ask for an extension of one week because we have already gathered all the necessary data for the completion. However, to our dismay, the project has been transferred to another analytical group within the company. This has been very disappointing for me. I have learned a lot from being a member of a team whose project was unsuccessful. This experience taught me to be a good team player and to manage my time more efficiently. Being a senior in the group, I had learned to manage and deal with the team who knew that we will not be able to finish the project on time. I have been instrumental in absorbing the stress my team and I were going through because of the short deadline. From this whole experience, I had also learned to recognize my strengths and the requirements of the task before accepting it. Even though my group failed to finish the project on time, we were still recognized for our work, and I took it as a reward. Therefore, I can say that even though our project was unsuccessful, the work and the effort was still recognized. As for me, I was able to gain knowledge from it and I consider it as an essential aspect of learning process. Failures should not be taken with disappointment. Each of us are strengthened and molded by ou r failures, they enable us the areas where we should improve and humble our hearts to be receptive to important lessons in life. A famous writer Rita Mae Brown had once said "Good judgment comes from experience, and often experience comes from

Why should you give blood Essay Example | Topics and Well Written Essays - 500 words

Why should you give blood - Essay Example Donating blood gives an opportunity to a donor to extend one’s concern beyond the narrow confines of one’s personal interest, so as to do something useful and unique for others. There exists no doubt pertaining to the fact that each and every unit of the donated blood do ends up saving some precious human life. So by donating blood one not only performs a beautiful and selfless act of service for the ailing humanity, but can also rest assured in the warmth of the truth that this donation will bring the gift of life to someone in trouble. Hence, donating blood on the one side saves human life and on the other side brings priceless joy, satisfaction and bliss to a donor. A blood donation literally stands to be a gift of life that a healthy and concerned citizen can give to one’s suffering and sick fellow humans. It is a unique way of paying back the society which provided one with multifarious advantages and opportunities. The second biggest incentive for donating blood is that it costs nothing. Everyone knows that almost each and every act of charity and kindness unavoidably costs something in terms of money or time. In fact there exist very few forms of social service that do not require a person to loose or sacrifice something in cash or kind. However, this does not stand true in the case of blood donations. If any person decides in the favor of opting for a blood donation that entire one stands to loose are a couple of minutes. It is a medical fact even the blood that a donor donates is replaced by one’s body in a matter of hours. So, one should donate blood because it is noble and costs nothing. It doe not matter whether an individual is male or a female, rich or poor, educated or illiterate, colored or white, almost every healthy human being can donate blood without loosing anything in terms of money or time. The biggest and the most pressing reason for supporting blood donations is that till date there

Ocean Carriers Essay Example for Free

Ocean Carriers Essay Iron ore and coal imports will most probably decrease the upcoming year With the increasing supply of vessels should result in a market surplus By creating this surplus, prices will be driven down, since we will have limited demand and suppliers competing Average daily rates, based on historical numbers, have a direct relationship with the number of shipments. Only Accept the project if we sell after 25 years in a tax free environment Reject all of the following; sell after 15 years in both a tax and tax free environment, also after 25 years with a tax environment The longer the wait to sell; the better How Long Should Vessels Operate? The company’s current policy is to not operate ships older then 15 years old If Ocean Carrier operates for 25 years the NPV will be higher then if they operate for 15 years and sell the scrap metal (,368,557 vs. $2,238,411) The present value of the future cash flows exceeds the value of selling the scrap metal 10 years earlier. Hence there is greater value operating the vessel for an additional 10 years/ Iron and coal’s demand is expected to increase annually and the charter rates are expected to increase by annually for the life of the vessel. The company can generate more income if they decide to operate the ship for an additional 10 years.

Street Car Named Desire Essay As we grow up it’s not only our age and experiences that make us who we are, relationships also shape our identity. All relationships will change our identity no matter who they are or what kind of relationship they have with us. Our friends shape our identity just as much as our family, if not more. This statement is very well depicted in the play â€Å"A street car named Desire by Tennessee Williams†. Throughout the play you see the different types of identities being shaped. If we are around someone enough we will start picking up traits of said person. If we are around someone who is always smiling and expressing themselves more than likely we will begin to express ourselves too. We gather the traits from those around us and our mind will tell us which are good and bad and try to get rid of the bad. With the good trait it will find our comfort zone with the person. That is why adults are always trying to get children and teenagers to understand that our friends are who shape us in a way. Our family relationships have a very big impact on our identity because we grow up with them. In the play the characteristics of each character was very much affected by their families. Blanche Dubois’ identity for example was shaped in a particular way because of her major losses in life. Her family fortune and estate we gone and she lost her young husband to suicide. This has led to her to have insecurities and making her a disrupted individual. Blanche’s fragile identity is also shaped by Stanley’s cruel actions towards her, also leaving her mentally detached from reality by the end of the play. However Stanley Kowalski’s identity in the book is very much shaped by the relationship he has with Blanche when arrives at the Kowalski household. Stanley’s intense hatred for Blanche is motivated in part by the upper-class past that Blanche used to have. He sabotages her because he does not appreciate the way she attempts to fool him and his friends into believing she is better than they are. From Blanche’s arrival Stanley has the need to feel like the man of house and does not take any orders from Blanche or Stella which is his wife. In the end, Stanley’s character is seen as harmful and cruel. The relationship between men and women is also a major identity shaper. Often in life the relationship between man and woman can be very unusual as sometimes a woman can have a lot of impact on men or the other around and sometimes they could have no impact. In the play Stanley and Stella’s marriage very much shape their identity. Shaping Stanley’s identity by making him feel like more of a man. Stella’s identity is very much shaped by the way Stanley treats her. Stella is a not very stable character because of the situation she gets into with her sister Blanche and her husband Stanley. Stella’s identity gets changed throughout the play because a lot of major events happen, such as her sister’s presence, having a baby and how Stanley beats her. Stella’s relationship with Stanley is both animal and violent but renewing as they always make up in the end. After Blanche’s arrival, Stella is torn between her sister and her husband. Eventually, she stands by Stanley, because she gives birth to his child near the end of the play. Stella’s denial of reality at the play’s end shows us that she actually more in common with Blanche than she thinks. The friend relationship between Stanley and Mitch also shape Stanley’s identity. Stanley is very loyal to his friends and would make sure that his best friend Mitch does not get hurt by Blanche. This is one of the main reasons that Stanley sabotages Blanche. Stanley would go through so much to just make Mitch believe that Blanche isn’t really who she says she is. Since Stanley is a misogynist, he sees himself as a superior to both Blanche and Stella, his need to â€Å"own† the house and be in charge is the motivator for his actions towards Blanche. Knowing that he was going to rape her from the very beginning, he tries and stops Mitch and Blanche from entering any type of relationship. â€Å"We’ve had this date from the start† In conclusion all types of relationships affect Blanche and shape her identity in a way. But in the end she lost her identity already because her husband died. In the play there are many relationships that shape the characters such as family relationships, friend relationships and â€Å"man and woman† relationships. In life relationships are a major source of shaping our identity.

Leaders Born Or Made Theology Religion Essay

Leaders Born Or Made Theology Religion Essay Many ask the question, are leaders born or made. Vince Lombardi stated leaders arent born, they are made. They are made by hard effort, which is the price all of us must pay to achieve any goal which is worthwhile. His quote suggests individuals are not born with the skills, gifts, or expertise needed to be a leader but with hard work, education, and experience an individual can become a leader. Aubrey Malphurs suggested leaders can be born and made. In her book, Being Leaders, Aubrey Malphurs (2003) speaks of a leaders possession of God giving capabilities (innate traits or abilities) and developmental capabilities (knowledge, skills, and emotions) and how combined they make up the leaders total capabilities (pp. 75-87). Malphurs book speaks mainly leadership in the church, but the information provided can be applied to any context. She defined leadership and built upon that definition by addressing the various components that comprise leadership. Several audits were provided to allow me to determine my strengths and weaknesses in relation to leadership. This leadership audit analysis is a summary of the results from the audits and inventories taken. Christian Leader Audit Christian leaders are Christian leaders outside of as well as inside the Christian community (Malphurs, 2003, p.13). A Christian leader can work in any context. They are able to guide, direct, and influence other individuals or groups in accomplishing a desired goal while bringing glory to God. Malphurs (2003) discussed eight core distinctives of Christian leadership, the second being committed to Christ. The Christian leader audit evaluates the strength of an individual as a Christian leader by assessing their level of trust, commitment, and faith in Christ. I scored a nine which indicates I am a strong Christian leader. The church and Christianity have been a major part of my life. I have a trusted relationship with Christ, I am committed, the Bible is the source of truth for everything that I believe, and I try my best each and every day to display Godly character. Servant leadership is something I try to display in the workplace and the church. In order to practice servant leadership, you must be willing to serve. As a leader I am willing to help out in any way that I can. An area that I continue to pursue growth in is leading by the power of the Holy Spirit. I want to increase my reliance on Him in leading and guiding my workers as we strive to be a better unit and in our work with families and children. I want to be sure all I do is to glorify God so that I my workers will see the Godly character in me and strive to do the same. Let your light so shine before me, that they may see your good works and glorify your Father which is in heaven (Matthew 5:16, KJV). Servant Leadership Servant leadership is the humble service of others based on our love for them (Malphurs, 2003, p. 34). One of our purposes in life is to serve God by serving others, because by serving others we are serving God. Servant hood requires us to be humble, selfless servants who seek to help others with love. The servant leader audit evaluates an individuals level of servant hood. I scored a 23 and my score indicates I am a strong servant. I entered the social work field because of my strong desire to help people. I get satisfaction from seeing families eliminate the barriers hindering them from improving their situations and ensuring children are placed in safe, nurturing, environments. In completing this assessment I found majority of the statements to be true. Malphurs (2003) mentioned four characteristics of a servant leader: humility, service, focus on others, and love (p. 34). In my work as a supervisor I truly believe I display all four characteristics. Humility is very important to me in leadership. I have never been fond of leaders who exploit their authority. I work with fellow supervisors who are quick to call attention to the fact that they are the supervisor, even outside the workplace. As a supervisor, I want my workers to be comfortable coming to me and not see me as a domineering individual but as someone they can trust and depend on to help them out. Some areas I want to continue to progress in as a se rvant leader are bringing out the best in others and to lead in such a way that people see me as someone who is willing to help others become all that God wants them to be. For we are Gods handiwork created in Christ Jesus to do good work, which God prepared in advance for us to do (Ephesians 2:10. NIV). Credibility Leaders must conduct themselves in ways that let people see them as credible or trustworthy. The credibility of a leader consists of having a unity between ideas, promises, actions, and achieving. Malphurs (2003) spoke of eight ingredients that contribute in various ways to building leadership credibility: character, competence, clarity of direction, communication, conviction, courage, composure, and care (pp. 56-66). The credibility audit determines the strength of the leaders credibility by examining the eight ingredients mentioned by Malphurs. I scored an eleven which shows I have high leadership credibility. Credibility or trustworthiness is very important to me. Credibility can make or break you especially as a leader. There is a saying, if youre going to talk the talk you have to walk the walk, which simply means back up what you say with action or do what you say you are going to do. As a supervisor, my workers are constantly watching what I do, listening to what I say, and determining if I have done what I said I was going to do. I communicate with my workers about what is happening and they trust me to be truthful and to share things with them. They know that I truly have their best interests at heart. They also understand there are some things, as a leader, I may not be able to share with them due to confidentiality. As I read the credible leader chapter of Malphurs book, I found that I must realize as a leader I will make mistakes and it is okay. I have always been a person who seeks perfection in all that I do. I want to do my best in whatever task I set out to tackle. Malphurs (2003) stated even the best leaders make mistakes (p. 67). Although we may make mistakes that can affect our credibility, we must realize there are steps that can be taken to regain it. Admitting the mistake, accepting consequences, and acting to correct the situation will allow us to regain trust and credibility when it is lost. Spiritual gifts All Christians possess a spiritual gift that is to be used to glorify God and to build up His kingdom. Many are not aware of their spiritual gifts or may feel they dont have one. Malphurs (2003) defines a spiritual gift as a unique, God given ability for service (p. 77). The spiritual gift inventory allows the leader to identify the gifts they were given and suggest ministries in which they may be effective. My highest scoring gifts were faith, giving, help, mercy, and administration. I found the spiritual gift inventory to be interesting and I was anxious to see my highest scoring gifts. Honestly, initially I was concerned that leadership was not higher on my list because I currently serve in a leadership role. As I reflected on my higher scoring gifts I realized that these gifts are essential for great leadership. My highest score was the gift of faith. I truly seek to grow in this area daily. I have learned through various trials and tribulations that there are many things beyond my control and total dependence on God is the only way to endure and progress. I find myself striving to do things in the will of God. Giving and helping were also high scoring spiritual gifts in my inventory. The spiritual gift of help would explain the strong desire I have always had to go into a profession in which I would be able to help others. My current job allows me to help individuals in various ways. I am able to help those who cant have children foster or adopt and help those who had their children removed from their home to get the services they need to be reunified with their families. I find great joy in my job. I would also consider myself a giver of money, time, and talent. Ive noticed that even in my season of struggling financially God continues to bless me to be a lender and not a borrower. In the giving of my time, I am a very loyal and dependable person. If I say I am going to do something, unless some extenuating circumstances arise I will do just that. Mercy was another high scorer. I believe it corresponds with the desire to help others and being a giver. As an individual who possess the spir itual gift of mercy, I am genuinely sympathetic, empathetic, and compassionate about others and how they feel. Natural gifts A natural gift, or talent, is an inherited or natural ability to do something. Unlike spiritual gifts, natural gifts can be possessed by believers and nonbelievers and usually given at birth. Natural gifts can be flourished with practice and training, but spiritual gifts can only flourish as we grow in God. The natural gifts and abilities indicator allowed me to observe the vocations and occupations that I have the strongest interest in. The highest vocational interests were social work and teaching and the occupational interests were social worker, teacher, and counselor. Teaching has been an interest of mine since I was a little girl. I vividly remember playing school with my doll babies and my chalkboard. I obtained an Associates degree in Early Childhood and transferred to the University of North Carolina at Wilmington to obtain my Bachelors. An assignment for one of my courses was to go to a local school and work with a youth one on one who was having difficulty. This experience allowed me to see that teaching in a classroom was not for me. It was discovered the child had ADHD. To see the child initially display the behaviors associated with the disorder and then to see him slow down to the point that he couldnt function a whole day at school and had to leave at 12:00 every day was too overwhelming. I realized that I would have a class of approximately 20 children and there would be children with ADHD and etc. that I would not be able to give that one on one attention to. Even though this experience led me to obtaining my Bachelors in Psychology a nd enter into the field of social work, I still have the opportunity to teach. I train individuals who are interested in being foster and adoptive parents and I love it. I truly believe I have a natural gift to teach or train. A natural talent I possess that was not mentioned in the natural gifts and abilities indicator is the gift of budgeting. In my current position as foster care supervisor I have to manage money on a daily basis. The gift indicator allowed me to see that I am using my natural talents everyday in my current field of work. Passion Passion refers to a strong emotion about something. Malphurs (2003) states passion focuses on what the leader feels strongly and cares deeply about (p.78). Individuals motivated by passion and desire tend to be more satisfied in their jobs. This satisfaction could lead to better job performance and less stress. The passion audit allows an individual to identify their passions. My passion appears to be the strong desire to help others, particularly children. My passion for helping others, especially children, gives me great satisfaction in the job that I do. The protection of children from physical abuse, sexual abuse, neglect, and dependency is my motivation. My goal in this field is to ensure that a child resides in a loving, nurturing, and safe environment. I am there to help and assist the parents and caretakers who are not able to provide such an environment due to barriers. I do believe there are times when an individuals desire to do something is diminished because of restraints. For example, as social workers in the child protective services unit, we have a passion for protecting children and helping families seek the resources they need to provide a safe environment. However, sometimes we seem to get so bogged down with the paperwork and other tedious aspects of the job that our passion seems to dwindle away. The paperwork is definitely necessary but sometimes overwhelming. We have a huge turnover rate because people come to wor k in the field to help others but find there is much more required that they did not necessarily think the position entailed (court involvement, documentation, paperwork/forms, and etc.). I sometimes find myself getting so caught up in the logistics that I tend to forget what motivates me to do what I do. My passion is to help others, especially children. Character Audit Character, referred to as soul work, is the sum total of a persons distinct qualities, good and bad that reflect who he or she is and affects what he or she does (Malphurs, 2003, p.80). The manner in which an individual interacts with and treats others displays who they are. A persons character can also be determined by the way they react or respond to situations. The womens character audit for ministry determines the overall strength of the leaders character. I scored a 21 indicating I am a leader of strong character who will prove credible to followers. A saying goes, you measure a persons character by how they act when no one is watching, and by the choices they make when they believe no one will ever know (Myatt, 2009). As a leader and an individual I seek to uphold a character that portrays my morals, beliefs, values, and knowledge, skills, and emotions. This is an area I continue to develop in. I have recently been experiencing some suffering in my personal life, suffering that I have seen tear others down. But God has allowed me to continue to grow and build my character and trust in Him. As a believer in Christ I know suffering will come and it comes to build our character and relationship with god. Suffering brings about patience, patience creates character and character brings about hope. I have found the experience of suffering is Gods way of showing is how we react in situations, which shows us where our heart really is. This experience can show us where we need to seek guidance and growth. Our character consists of our hu mility, passion, credibility, knowledge, skills, and so much more. Â  For I know the plans I have for you, declares the Lord, plans to prosper you and not to harm you, plans to give you hope and a future (Jeremiah 29:11, NIV). Conclusion Leaders are born and made. There are some God given capabilities (spiritual and natural gifts) that leaders receive at birth or when they are born again in Christ that can bring strength to a leadership role. Malphurs (2003) states a leaders gifts provide them with special abilities needed to carry out their ministry so leasers would be wise to know what their spiritual and natural gifts are and what gifts are needed to lead in their specific area of service (p.78). Leaders also possess God given capabilities they werent born with and that can be improved over time. Malphurs 92003) named at least four developed capabilities a leader must possess: character, knowledge, skills, and emotions (p. 80). Malphurs book, Being Leaders, allowed me to conclude you dont have to be born a leader. Leaders can be made with hard work, increased knowledge, skills, and with faith in God. The audits and inventories allowed me to assess my strengths and weaknesses in leadership. The information obtained will enable me to build upon my strengths and continue to develop my weaknesses. The gifts or talents the Lord blessed me with at birth (passion to work with children and the temperament) enabled me to lead in my current workplace and the skills, knowledge, and training I have received and continue to receive has allowed me to become more effective.

The Relationship Between Crime and Guns in the United States :: Second Amendment The Right To Bear Arms

The right to bear arms is an American right featured in the second Amendment of the Constitution. In the 18th century when the constitution was written, times were different, there was a need for citizens to arm themselves to insure the safety of the society as a whole. In the modern world, the police department preserves the safety of society and there is no need for citizens to carry weapons. The founding fathers of the Constitution could never have imagined the horrendous outcome of their actions. Every year too many lives are claimed as the result of American's owning an excessive number of firearms. Compared to other western countries that have considerably stricter gun control laws America is still viewed as â€Å"The Wild-Wild West† (ARPP, 66). However, is there a relationship between crime and firearms? In this second amendment our right to have a gun, are we dooming ourselves with higher crime rates and more horrific crimes just to have the right to have a gun in our house? This paper will set forth and find the results of studies conducted to find a conclusion. This is a very important issue when it comes to sociology and our society. The importance of violence and force as sources of power has only recently begun to achieve recognition among sociologists. Power has traditionally been conceptualized as deriving from lasting attributes of persons and from their position in the social structure such as sex and race. However, when power is examined at the interpersonal level it is typically viewed as deriving from family role and gender. These sources of power ultimately derive to some extent from a capacity to use physical force and violence. This capacity often relies partly on a rather transitory attribute of the person, the possession of weaponry. The single most important factor that sets human violence apart from aggression among lower animals is arguably the human’s greater technological capacity to inflict harm on another creature. These â€Å"tools of death† are readily available to humans and are vastly more lethal than even the most deadly natural equipment of any other species (Kleck, 670). Yet, little is known about the impact of weaponry on violence or how weaponry is used to coerce compliance in hostile social encounters. Firearms are seen as violence enhancing devices, it is just assumed that the possession along with the use of firearms increase the chances of the victim to be injured or killed.

Anxiety Disorder Essay -- Psychology, Phobia, Agoraphobia

Among many psychological disorders, anxiety disorders are the most predominant in the United States. According to Antony (2011), anxiety disorders affect nearly 28.8 percent of the population. An extreme and unrealistic anxiety is the most common symptom that characterizes all the psychological conditions within the category of anxiety disorders. The category includes specific phobia, agoraphobia, social phobia, panic disorder, post-traumatic stress disorder, generalized anxiety disorder, and obsessive-compulsive disorder. This paper examines obsessive-compulsive disorder discussing the major etymological explanations of anxiety disorders in general, specifically describing the condition, and discussing actual treatments for the disorder. Anxiety played an important role in the psychoanalytic theory, and, as a result, psychoanalytic interpretation is important to understand anxiety disorders. In the psychoanalytic interpretation, anxiety is defined an intense sensation of endangerment and an unconscious mechanism produced by unconscious conflicts. According to Wolman and Stricker (1994), it can be understood as a symptom that is the cause and effect of itself and a product of past experience, psychological mechanisms, and psychic contents like persecutory anxiety or separation anxiety. For Freud, nervous anxiety was produced by sexual frustration and repressed sexual drives, or libido. In his theory, sexual frustration creates a biochemical imbalance that results in anxiety. However, this idea does not have support on the empirical basis because there is not a biochemical process that correlates with Freud’s theory. In addition, on the psychological basis, sexually abstinent people do not always experience ext reme anxiety (Wolma... ..., and pharmacological treatment would be better in the case of patients with obsessive-compulsive disorder. In this sense, the patients would be encouraged to examine their beliefs or assumptions that create their compulsions. The etymological explanations of anxiety disorders represent the bases for the creation of any treatment for obsessive-compulsive disorder, while they increase our knowledge about the condition. Since diagnose is extremely related with the severity of the symptoms, the correct treatment approach is also related with the state of the condition. Future research is needed to enhance our knowledge and understanding of the causes and elements that contributed to the condition’s occurrence. In conclusion since every treatment has its limitation, a combination of different treatment is the best methodology to treat obsessive-compulsive disorder.
