From undertaking that specific module, it follow throughms that rate heed is mostly used as a tool to achieve judge for silver for Clients. Working for a Contractor for 4 and a half years now, I construct only ever seen place Management used on one Construction Project and this is the one that I am currently based on just now. From my experience, I feel that pry Management has a deal of advantages for Contractors as well as Clients and I wanted to find out why it is non being used to a great purpose by Contractors.Get help wi th your essay from our expert essay writersIndicative Title lever Management A Contractors Perspective1.3 The AimTo determine the reasons as to why harbor Management is not being greatly used by Contractors in the Construction Industry.1.4 The Main ObjectivesIn order to achieve the higher up aim the following objectives must be metTo identify the divulge principles and elements of harbor Management.To identify techniques and working practices adopted and to identify the benefits of Value Management.Examine the reason as to why Value Management is not widely used in the Construction Industry.Critical analysis of the views of Main Contractors about the benefits or mindless comings of Value Management.To propose recomm block offations for improved implementation of Value Management for Contractors.CHAPTER 2LITERATURE REVIEWVALUE MANAGEMENT2.1.1A DefinitionValue Management is a ardor of management particularly dedicated to motivating stack, developing skills and promoting synergi es and innovation, with the aim of maximizing the over both achievement of an organization.The Institute of Value Management online http//www.ivm.org.uk/vm_whatis.htm Accessed on 18 July 2007.Value Management is a squad based process-driven methodology. Its incentive is to deliver a product, service or count on at optimum whole life performance and cost without detriment to graphic symbol.By using teams of experts in the Construction Industry, this allows the Value Management process to identify design and construction solutions which offer the best nurture for money with regard to the rangeal requirements of the ClientKelly, J. Male, S. (1988) A Study of Value Management and Quantity Surveying PracticeValue Management plays a key role in the Construction Industry for continuous improvement and innovation.The Background ConceptValue Management originated in the United States of America in the new-fashioned 1940s and the process was originally used in the manufacturing indust ry. This was soon adopted by the Construction Industry in the UK by the head start of the 1990s as unlike studies highlighted between 36% and 45% savings on estimated construction cost to the ClientKelly, J. Male, S. (1988) A Study of Value Management and Quantity Surveying PracticeThe concept of Value depth psychology was introduced by Lawrence Miles in the 1940s. Miles, a Purchase Engineer working for the General Election, had to find way of lifes to tackle the bodily shortages which was due to the Second World War. Miles sought to find option materials that would tolerate the same function. This proved effective as Miles found that many of the secondary products he was finding were of an equal, if not rectify quality than that originally proposed. In addition to this he found that many of these alternatives were at a lower cost. Dallas (2006) states that a short while later, people realised that not only did the technique stick out a way to substitute alternative materi als but it was also an excellent way to reduce costs while still maintaining the necessary functionality. This system would involve value and analysis and based on this Miles developed the definition of Value Analysis.An nonionized approach to providing the necessary functions at the lowest cost.Kelly, J.R. Male, S.P. Graham, D. (2004) Value Management of Construction Projects.To further enhance this Miles provides further definitionValue Analysis is an organised approach to the realisation and elimination of unnecessary cost.Kelly, J.R. Male, S.P. Graham, D. (2004) Value Management of Construction Projects.Key Principles of Value ManagementThe institute of Value Management states that the key principles of Value Management ar different from other styles of management in that they include attributes that are not normally found togetherManagement Style furiousness on teamwork and communicationA focus on what things do, rather than what they are (functional approach)An atmosphe re that encourages creativity and innovationA focus on customers requirementsA requirement to evaluate options qualitatively to enable robust comparisons of optionPositive Human DynamicsTeamwork encouraging people to work together towards a common solutionSatisfaction recognizing and giving creditCommunication bringing people together by improving communication between themFostering demote common understanding and providing better group decision supportEncouraging change challenging the status quo and bringing about in effect(p) change self- exit the assumption of ownership of the outcomes of Value Management activities by those responsible for implementing themConsideration of External and Internal EnvironmentExternal conditions taking account of pre-existing conditions out-of-door to the organisation over which omnibuss may have little influenceInternal conditions within the organisation there will be existing conditions which managers may or may not be able to influenc eDegrees of Freedom the external and inhering conditions will dictate the limits of potential outcomes and should be quantified.Effective Use of Methods and Tools actor of achieving outcomesThe Institute of Value Management online http//www.ivm.org.uk/vm_whatis.htm Accessed on 18 July 2007From this we can see that Value Management brings Construction teams together and gets them to communicate more effectively with separately other, this in turn will have a beneficial effect on the Project. The functionality of a Project will be more focused on being able to achieve Value for Money.Value Management Techniques Function AnalysisFunction Analysis is a powerful technique in the identification of the principal functional requirements of a projectSeeley, I. (1997) Quantity Surveying Practice. Second Edition.Function analysis is basically a brain storming session with all people involved in the construction project and is used to determine the main needs of a project in order to focus o n alternative options that are less expensive although still achieving the functionality as required.FAST DiagramsSeeley (1997) states that the FAST (Functional Analysis System Technique) has evolved from the functional analysis approach as it establishes a power structure of functions in order of importance.FAST diagrams are a more effective way of showing the main important functions and needs of a project.Bolton (2002) verbalise that function analysis was key to success in a workshop and always uses a FAST diagram.Pasquire and Mauro (2001) cite Norton and McElligott (1995) who suggest that the use of FAST may provide more benefit in the early stages of a project but not so much in the construction phases. It is also highlighted that FAST schematisation requires experience and training on the part of the facilitator to ensure it accurately depicts the function of the project. Another constraining factor is the time required to complete FAST diagrams.Hunter, K. Kelly, J. (2006) I s unrivaled Day Enough? The Argue for Shorter VM/VE Studies.Value Management WorkshopsValue Management Workshops are one of the main techniques of Value Management. This will be discussed in great detail in Chapter 2.2.Benefits of Value ManagementAfter several pack-project examines with Contractors and Consultants, Kelly Male identify various positive aspects of the Value Management process. The most significant of these areProof that the initial design was indeed the bestPeace of mind to the owner that he was receiving good value for moneyIntroduction to higher quality productsBest up-to- get out technology at least costA clear focus on project objectivesAn alternative view of the design modify project programmesImproved site management structuresAn probability for a detailed analysis of the required projectKelly, J. Male, S. (1988) A Study of Value Management and Quantity Surveying Practice.The Institute of Value Management indicates that Value Management has already been s uccessful in achieving Value for Money for such Clients as BP, British Airways, Pfizer, Stanhope and various water and rail companies. This has resulted in the public sector adopting Value Management techniques in order to cut down construction costs and achieve better Value for Money.Benefits of Value Management according to the Institute of Value Management focus on greater communication and understanding within the Construction team but do not seem to focus on the cost benefitsBetter business decisions by providing decision makers a sound basis for their alternativeImproved products and services to external customers by clearly understanding and giving due priority to their real needsEnhanced competitiveness by facilitating technological and organisation innovationA common value culture thus enhancing every members understanding of the organisations goalsImproved internal communication and common knowledge of the main success factors for the organisationSimultaneously enhanced communication and efficiency by developing multidisciplinary and multitask teamworkDecisions which can be back up by the stakeholdersThe Institute of Value Management online http//www.ivm.org.uk/vm_whatis.htm Accessed on 18 July 2007Sir Michael Lathams report Constructing the Team (1994) states the benefits of Value Management and includes Value Management as a factor which is critical to the success of projects in providing the basis for improving value for money in construction.Hogg, K. (1999) Value Management A Failing Opportunity? Nottingham, The Nottingham Trent University.Value Management is still not being used to a great extent in the construction industry despite the great number of benefits.The reasons for the unmingled hesitance of the industry to adopt Value Management on a greater scale are unclear since the benefits of Value Management appear to be widely recognised and the practice continues to be promoted at a high level.Hogg, K. (1999) Value Management A Failing O pportunity? Nottingham, The Nottingham Trent University.Value Management Workshops before a VM workshop commences learning has to be gathered to determine its objectives and deliverables and therefore what shape and form the workshop will take.Male, S. Kelly, J. et al (1998) The Value Management bench mark A Good Practice Framework for Clients and PractitionersValue Management Workshop StructureKelly (1996), details the key stages involved in a Value Management WorkshopValue Management workshops are characterised by a three stage processThe Orientation and Diagnostic Phase in which the value manager prepares for the study by meeting with the project sponsor and key players who will be involved in the study, reviewing documents, conducting interviews and briefings and preparing the agenda for the Workshop Stage.The Workshop Stage is where alternative or complementary views on the value problem are brought together through a structured team based activity facilitated by a value mana ger and progressed through the application of specific team based techniques. Innovative ideas are brought forward to satisfy the functional requirements identified against a backdrop of the value criteria uncovered. A workshop report will be produced including an Action Plan to ensure that value solutions and options will be implemented in the post workshop phase.The Implementation Phase in which the Action Plan is followed through by those responsible for the investigation and implementation of ideas.Kelly, J. (1996) Value Risk Appraisal raise NotesThe International Benchmarking Study (1998) identifies the Implementation Phase as one of the key areas in which Value Management fails. At this stage the Value Management team have identified and adopted various approaches to ensure that the Value Problem is minimised as far as possible through various meetings and workshops in the forward phases. At this point an implementation strategy will be discussed with the applicable parti es and if possible those involved in the implementation will be interviewed and identified in the action plan at the close of the workshop phase.Value Management Intervention PointsThere are three main stages of Value Management workshops and they all produce a great deal of teaching that is discussed between the Construction parties to find alternatives ways of constructing the building and focusing on achieving Value for Money. These stages are depict on the next page. Strategic BriefingThe Strategic Briefing stage deals with identifying the broad scope and purpose of the project and its important parameters. The focus is on determine the strategic needs and wants, and the role and purpose of the project for the Client. Project BriefThe Project Brief translates the Strategic Brief into construction terms, specifying performance requirements for each of the elements of the project including spatial relationships and detailsA summary of the germane(predicate) parts of the Strateg ic Brief documentThe aim of the design. This would include priorities for project objectivesThe site, including details of accessibility and preparationThe size and configuration of activitiesOutline specifications of general and specific areasA cost centred budget for all aspects of the project including all elements of the construction projectServicing options and specification implications e.g. security, deliveries, access, etc.Kelly, J.

(1996) Value Risk Appraisal Lecture NotesBenefits of Value Management WorkshopsThis is an extract from a journal that describes the benefits from an actual Value Management workshop that took placeAll team members support their commitment to continuous improvement. Only three did not feel that it had been as a result of the workshops. The team unanimously believed that more options had been explored within the team and all agreed to that being as a result of the workshops. A principal finding under the section of workshop effectiveness agreed to by all members of the team, was that the workshop provided a good basis for teamwork, created and atmosphere of equality, ensured open and frequent communication and focused the participants on action and achieving results. The team members that indicated tea m working, cultures and communications as issues prior to the workshops agreed that they had all been resolved through the facilitated workshops.Hunter, K. Kelly, J. (2006) Value Management Workshops and Partnering Conundrums.From this extract we can see that there is a great deal of benefits for all parties by using Value Management workshops. There are also advantages to a VM workshop if the environment is isolated, these includeIt focuses the team on the project maternal quality occurs during the workshop processIt commits the teamMilitates against partial attendanceContinuity is ensured.Male, S. Kelly, J. et al (1998) The Value Management Benchmark look into Results of an International Benchmarking StudyRDT Pacific (2007) stated that there are other advantages of Value Management and Workshops.Value Management consistently provides significant improvements to projectsAverage capital cost savings of 14% (NSW organization look into)The forging of dedicated, synergistic projec t teamsAuditing on the project brief and the decision making processProvision of additional functionality within existing budget allocations teaching of a structured process to move projects efficiently to the next stage and ultimately completion.RDT Pacific online http//www.rdtpacific.co.nz/services/servicesportfolio/valuemanagement.shtml Accessed on 5 October 2007From this enquiry we can see that there is a great deal of benefits of using Value Management for all parties involved in a Construction Project. It is the intention of this research newspaper to find out why Value Management is not being used a great deal by Contractors and therefore this research will provide beneficial when it comes to interviewing Contractors on their views of Value Management workshops. A comparison will be made between the benefits and injustices of Value Management in the look for Analysis chapter in order to suggest suitable implementation of this process for Contractors.CHAPTER 3RESEARCH METHO DOLOGY3.1 Secondary Method of seekThe Secondary Research Method proposed includes investigating historic papers and publications to assess the extent to which Value Management is used in the Construction Industry. Information will be obtained from books, journals, websites and voice communication notes. The Glasgow Caledonian Library will be used to obtain books. The RICS (Royal Institute of Chartered Surveyors) and various websites will be used to obtain journals and information on Value Management.These methods of research are being used as they are readily available. About 6 books from the Glasgow Caledonian Library were used for research and a lot of information was found, however, the negative aspect of using books is that the information may not be up to date. Lecture notes from the Value and Risk Appraisal were used for the Literature critique in order to explain the processes of Value Management. They were produced by Professor John Kelly who either wrote the notes from h is own experience or took extracts from books. A great amount of information was found from the internet on Value Management and this was also used to prepare the Literature Review. Information from the internet can be up to date although the discriminate is that it can be someones opinion and may not be entirely true. Journals on Value Management were found on the RICS website, Athens and also on the Construction and Building News websites. Some journal information was also taken from the Glasgow Caledonian Library. The advantage of Journals is that there was a lot of information available and peoples views are expressed which is helpful for determining any problems that exist in Value Management.This research will extend the authors knowledge and understanding of Value Management and will also give an insight into the varying views on the subject.3.2 Primary Method of ResearchThe initial Primary Research Method proposed for this paper is to use actual Construction Project Case S tudies in an attempt to find out how beneficial Value Management was for those projects. A few case studies were found on Projects that have used Value Management and they will be used to determine whether Value Management has been a success or not for the Project. Case Studies are useful for this research as they can be used to contrast and also get peoples views on Value Management.A second Primary Research Method proposed for this paper will involve interviews with relevant Construction Industry personnel to gain their views and perspectives of Value Management in Construction Projects. Suitable candidates will be mainly Contractors who have worked with Value Management on their previous Construction Projects and also the Chairman of the IVM (Institute of Value Management) in order to achieve the objectives of this paper.The purpose of these interviews is to gain a greater insight into the Value Management process and how there can be an improved implementation for Contractors. It is important to choose the correct questions to collect data to prepare a relevant analysis. Interviews are better for communicating as you are face to face to a person and the interviewer is responsible for getting the quality of information that is required. A disadvantage of interviews however can be arranging meetings with the suitable candidates as they may not always be available when you are. To control this, contacting the interviewees at the earliest opportunity is always recommended.3.3 Research Methodologies RejectedHaving chosen the above methods for research it is important to note that alternative options such as questionnaires and electronic surveys were considered for potential sources of information. However, it was felt that these options would not provide the quality of response and feedback that the other methods would for this research. Questionnaires and electronic surveys would require time to fill in and most construction personnel would probably not have the time required to complete them or would simply disregard the emails or paper copies as they would feel it would be too time consuming. Another disadvantage of these research methods is that the questions could be interpreted the wrong way or the quality of answers could not be as good as asking someone in person.CHAPTER 4PROGRESS TO DATE PLANNED FUTURE WORKProgress to DateAt this stage, the indicative title, main aim and main objectives have been agreed. Research was undertaken throughout the summer on the topic of Value Management and the relevant materials were collected. Books, journals, case studies and website information were read and notes taken from each to form the basis for the publications review. The literature review has now been completed and also most of the information for the Date Analysis Chapter in the Final Dissertation report has been collected, such as books, journals, website information and journals. Everything required for the Dissertation Interim Repo rt is now complete.4.2Research MethodologyThe final piece of methodology to be collected will be from interviews with Construction personnel which are still to be agreed and also the interview questions need to be created. These are both due to happen at the start of the New Year and the planned interviews should take place towards the end of January 2008 at the latest.4.3Research Analysis and ResultsOnce the interviews have been conducted, an in depth analysis of the views will be undertaken, along with analysis of the information of other Construction personnel from the data collected via journals, case studies and books. This section will be undertaken from February 20084.4 Conclusions and RecommendationsAt this stage, it will now be time to come to a conclusion and give recommendations on how to implement Value Management for Contractors. This section will be undertaken near the end of March 2008.4.5 Structure of the Final DissertationBelow is the structure proposed for the fina l Dissertation document to be submitted in April 2008.Chapter 1 IntroductionChapter 1 introduces the principle for study of the dissertation topic and the indicative title. It also determines the main aims and objectives, the research methodologies to be used and a structured breakdown of each chapter.Chapter 2 Value ManagementChapter 2 will focus on the background of Value Management and mainly on the key principles, techniques and advantages and disadvantages of this topic in the Construction Industry.Chapter 3 Value Management WorkshopsChapter 3 will focus on value management workshops in the Construction Industry and highlight the main advantages and disadvantages of this approach for Contractors.Chapter 4 Value Management in Previous Construction ProjectsChapter 4 will focus on case studies of previous construction projects that have used Value Management. They will be used to determine whether Value Management has been beneficial or not in the completion of the Projects.C hapter 5 Research Analysis and ResultsChapter 5 will analyse the information and feedback obtained from the interviews to be conducted. Chapter 5 will also compare the responses to identify the differences in opinion.Chapter 6 Conclusions and RecommendationsChapter 6 will set out the conclusions that have been established with reference to previous chapter literature research and the interview feedback responses. Chapter 6 will also discuss to what extent the aim and objectives have been achieved in this research paper. The author will finally give recommendations for improved implementation of Value Management for Contractors.ReferencesThis section provides a list of all references used for this research which are quoted within the paper and will also provide readers with the sources of views and opinions expressed as a follow-up or extended research on the topic.BibliographyThis section will provide a list of all other references used in preparation of the paper but not directly quoted.AppendicesThe appendices section shall provide the reader with supplementary information to that provided within Chapters 1 to 5.Programme of Future WorkProduce research questions for interviews Start January 2008Conduct research interviews End January 2008 entropy Analysis of interview results other research methods February 2008Conclusions and recommendations End of March 2008Final Dissertation hand in April 2008LIST OF REFERENCESDallas, M.F.

Environmental Toxicology and Human Health
Environmental Toxicology and Human HealthEnvironmental Toxicology and Human HealthEnvironmental Toxicology is a field of science with various disciplines involved in the chew over of the adverse effects of various physical, chemical and biological agents on living organisms particularly animals, birds and fishes (Philp, 2001, pp. 10-11).Physical agents.They are sources of energy that whitethorn have negative effects on human health and that of biological organisms such as fish, birds and animals (Philp, 2001, pp. 20-25). One such agent is noise which posterior be defined as outcast sound. Noise has both permanent and temporary damage to the ears rendering one incapable of hearing or resulting to tinnitus both of which are irreparable (McCally, 2002, pp. 58-67). Noise in the workplace also poses a threat to the workers in that they may fail to hear sounds indicating threats. Vibration, also a physical agent is categorized into two hand-arm oscillation (HAV) and whole body vibrat ion (WBV). Continuous photograph to HAV has been proven to lead to hand-arm vibration syndrome a permanent and incapacitating health effect such as musculoskeletal disorders of the hand (McCally, 2002). On the other hand, continued exposure to WBV is associated with disgustful pain on the lower posterior. Optical radiation also has some sombre effects on the health of people. Ultraviolet radiation emanated by the sun presents the utmost danger to our health. When exposed to the eyes it may lead to spoiled cornea and laborious pain magic spell exposure on the skin may vary from burning, redness and hastened ageing through skin stoogecer of different types. Electromagnetic field (EMFs) generated due to electrical energy used may also be detrimental (Philp, 2001). Though they seldom occur, constant exposure to the EMFs can result to life-threatening effects depending on the frequency of the radiation. Electricity can also be viewed as a threat since it may lead to death or severe injuries such as electric burns, thermal burns and electric burns to people. Last but not least we have ionizing radiation. Contact with low-level ionizing radiations may lead to cancer and DNA mutations while high-level exposures political campaign radiation sicknesses and burns (Philp, 2001).Biological agents.These include bacteria, viruses, fungi, other microorganisms and toxins associated with them. While some of these agents have no harmful implication on the human health, others have the potential to affect the human health in various ways ranging from moderately mild, allergic reactions to drab medical illnesses even demise. These agents occur widely in the environment (Environmental Toxicology And Human Health, n.d.). Biological agents have the capacity to reproduce rapidly, require little resources to live and can poison at very small venereal infections thus they are a probable danger in a widely in our environment. Biological agents can be categorized into four sets a ccording to their severity of infection and likelihood of prevention and treatment (McCally, 2002, pp. 150-200). Group 1 agents are those with low chances of causing ill effects to the organisms. Group two consists those toxicities that are unsafe for the workers but chances of spreading to the community are very minimal. Group 3 agents are those that can cause severe human disease, pose a serious threat to the workers and are likely to spread to the community. However, these toxicities can be treated. Group 4 agents are alike(p) to class 3 agents except for the fact that there is no effective management for them. These are some of the most contagious and extensive biological agents anthrax, botulism, avian flu, and Ebola (Environmental Toxicology And Human Health, n.d.).Chemical agents.These are as a result of the products we use in our day to day doings. Pesticides are a perfect instance of chemical toxins (Lakind). Pesticides persist in the environment long after their use whic h can result in bioaccumulation of chemicals in various organisms along with biomagnification within a group of organisms that depend on each other for food. Dichlorodiphenyltrichloroethane (DDT) is another agent that was banned due to its negative effects on living organisms (Lakind). The reactions chemical toxicities is strung-out on several factors that I will briefly discuss. Age is a significant aspect in establishing the response to a toxic chemical (Lakind). For example, parathion is much lethal to young animals. Although very rare, sex can determine the response to a toxicant. For instance, when exposed to parathion the female rat is twice as affected as the male rat. The responses to a toxic chemical also depends on the species (Safe). For example, insecticides are lethal to insects but relatively non-toxic to animals. Toxicity of a chemical is determined by factors such as the dosage-it is the most critical factor if a substance will be acute or a chronic toxicant (Lakin d). The public figure that a chemical agent is in also defines its toxicity. For instance, the poisonousness of mercury in gas form is very different from methyl mercury. The entry point of a toxin is also a measure of its toxicity. One other factor is the rate of removal from an organisms system. According to Paracelsus all substances are poisons only the dose differentiates whether it is a poison or a remedy (Safe).Exposure assessment is the process of establishing the regularity, period and expansiveness of exposure to toxicities together with the traits and number of the population exposed. Methods of exposure assessment include direct and indirect approach (Philp, 2001, pp. 100-108). In direct approach exposure to the agents is determined by monitoring the pollutant concentrations reaching the person while in indirect approach the toxicant concentration is measured during specific human activities to predict the exposure distributions within a population (McCally, 2002). Epide miology is important to look for studies of environmental health since many environmental exposures can be addressed only by comparing populations instead of individuals and the interruption of both local and normal environments require us to come up with new methods of study design that is epidemiology. The epidemiologic approach to studying environmental health problems has its limitations. One of such chasteness is the quick changes in the health and nutritional status of many populations that have been affected majorly which may lead to inconclusive results (Safe). Another limitation is the fact that information collected through epidemiology is often ignored and limited by factors such as limited resources, personal priorities, political concerns and public relations (Philp, 2001). Since epidemiology depends on reasonable info, restriction on the gathering of data can be considered a constraint. This may be due to insecurity or lack of resources preventing the researchers from submitting surveillance data (Safe).References.Environmental Toxicology And Human Health. (n.d.).

Honour and Fidelity Varies for Men and Women in the play Much Ado about
The theme for comply and fidelity apply for both men and women in Shakespeares play much ado about nothing. whiteness and fidelity is represented very differently for men and women as it would have been for the people in Elizabethan times. In this first section of the essay, I allow for be exploring double standards and Shakespeares awareness of the double standards between sexes and his feminist approach, the differences of honour and fidelity for men and women and upper class and lower class comparisons.In order for men to be honourable, they should do great deeds in war which gives them comfortably recognition. From the very beginning of the play we see evidence of this when Leonato says in act 1, scene 1.Leonato I find here that bestowed much honour on.Claudio. Deeds in war of course come hand in hand with reputation and a good score which plays an big role in the play. Another quotation showing the importance of a good name is where Hero talks to Ursula about Benedick in t he garden scene in Act 3 Scene 1.Hero Indeed, he hath an excellent good name. Another important aspect of honour and fidelity for men are friendship or comradeship. The mens loyalty to their friends was very important as it showed that they were trustworthy and could bestow that trust upon each other. In 1164 Beatrice says He hath every month a new utter brother, at this point Beatrice and Benedick arent getting on so well she states this as to mock him and later says that He wears faith as the means of his hat. For women, honour and fidelity meant very different things to what it did for a man. In order for them to gain honour and fidelity, they had to do very things in order for it to be achieved. Women do not expect fidelity from men... ...s many times as he likes the more the better in a mans world so far if a women was to sleep around then she would be considered a whore and would be slated for it. This shows that although women have a lot more rights in the modern world, t he rules in sexuality and honour have not changed a great deal since Shakespearean times.In conclusion, Shakespeare has used the concept of honour and fidelity throughout the play. He shows many different aspects of honour and fidelity through his characters, the contrasting differences between men and women. He shows us what how important these traits are to Elizabethan society and if honour was ever lost in the upper classes the consequences were never too pleasant. Shakespeare even shows us the true loyalty between Benedick and Beatrice which gives and insight to his feminist views which were sooner modern for the time.

The Search Essay example -- Creative Writing Search and Rescue Essays
The SearchI used to work for the F.B.I., in the Portland office. It was mychildhood dream to be the one who gets the problematical guy.My fiftieth birthday was in solely three months. I had a wife and threechildren, in time do, and the same job Id had since my graduation from Quantico.We were living just outside Portland. My oldest son, John jr., was in his thirdyear at Washington. The twins were high school seniors at this time and mypride and joy, daddys little girls. Carolyn and I had historied our twenty-fifth anniversary, thats the silver one I think, the previous Thursday night.That warm July morning, I dressed for work as I had every other. Blacksocks and slacks, a pin striped white dress shirt, and a black jacket. Islipped on my loafers but was lost in the search for my tie. Coffee stained andstill unwashed, I found it laying on the laundry room floor. I swore to myselfto let Carolyn know about that. I walked into Johns empty room, knowing he have some ties. It was just as he had left it, I guess, because Id neverreally gone in his room. I picked the red one he wore in his graduationpictures and slipped it over my head. I stepped into the bathroom, combed backmy whitening hair, and left for the office.The early morning sun shone in through the broken blinds that I noticehadnt been replaced as I asked. I looked over the pile of paperwork awaitingme. Why the hell do I gotta do all these damn reports?Actually, you dont, not today. I false to see a man much like myself,but older and with his piece on. He was a little taller, but with the samesagging features and broad belly of my body. Ive come here to give yousomething new. With that, I was handed a thick manila folder. It felt like itcontained a video cassette. All you hold is in there, including my card. Thisis top priority, Agent Caulsworth. You will report to me on the hour with yourprogress. The paperwork here will wait. The man turned and left. Outside, Iheard a jet-copter lightly lift off. F unny I hadnt heard it land.I poured out the contents of the folder, the federal statement, a casehistory, vid cassette, and a dossier. The card that fell to the floor sayFederal Marshall Wilson R. Franklin. He was from the Boise office.Must be real important for him to come all the way out here. SteveMenschke was my oldest fr... ...was the only thing that mattered to me, and hes allthats left.I reached into my pocket and withdrew the tie. Mud concealed the redfabric. I tried to think of John. My mind strained to see his face, hear hisvoice. A tear rolled eat up my cheek and fell off my chin onto the tie. Iloosened the knot and slipped it back over my head. With my sleeve, I wiped myface.I lifted the flashlight, switched it off and tossed it to him. Take it.I turned away and started back into the world.Hendricks team found me a few miles west of the hole. They airlifted meto the Olympia hospital. I was treated for a broken clavicle and lift blade,along with my ribs. The tissue da mage to my back and side was extensive and Ihave little use of either. After two days they released me.The next day, I received a call from Franklin, in Boise. I was commendedby him for putting myself on the line. He granted me early retirement, and abonus for being injured. He asked if I might know anything about thedisappearance of David Brown from his grandparents house in the middle of thenight. I told him I did not. I bid him farewell, hung up, and dialed Johnsnumber at school.
