Enhanced Entity Relationship Model Information Technology Essay

Enhanced Entity relationship manikin Information Technology EssayDatabase is very of the essence(p) for whatsoever application in the real world. In newfangled days companies ar looking for cost cutting, if they apply cost cutting outgrowth in the infobase design stages then there give be modifications or rebuilding the infobase after implementation. They will leave with high budget for the compevery. To create an efficient and appropriate database for an application it should be a good idea for any developer to follow certain database design steps. Bad database design will lead company to losses as well as client un-satisfaction. In play days many of the database designs be failed because of wrong user requirements. Collection of user requirements is main and first step in the database design process. If a developer took wrong self-assertion on the requirements then it results a bad database design. So the developer should be well experienced in database design.In th is embrace I am going to let off slightly the importance of standard database putling tools such as ER, EER and Use eccentric person gravelling, character of the database design and the factors affecting property of a database design. Many of the examples which I am going discuss in this report are from the given scenario to me namely The Stanwell Parish Register.Database designIn any application building there are two main steps first superstar is database design and former(a) is front end design. First step is to build database, based on this design developers will build front end design. So the database design is pillar for any application. In these days we can hardly see the applications without databases. Now I am going to discuss round the notions in database design process. For the successful creation of a database there are three concepts to follow. They areConceptual data manakin This is the initial and important step in the database design process. This will represent completely the business rules applied for the particular database. Conceptual data imitate is a diagram which shows the campaign of business among all the important entities winding. It doesnt show any relationships and constraints.Logical data mold Logical data dumbfound is the other step in database design which comes after conceptual data specimen. According to Shelley Doll (2002) The logical design of a database involves taking the business information observe in a conceptual data stupefy and translating it into an empirical layout of the data, usually in a relational style. It deals with the relations among the entities and attributes as well as the constraints. It doesnt tizzy about the implementation of the database design.Physical data model This is the final step in database design process. Physical data model deals with the implementation of the logical data model and also about the data in it.Each concept stated above is important for any database desi gn. whatsoever experts may skip one or more steps in design process they will repent about it later. My intention here is not to explain and show the process of database design whole. Before going in detail about my task I would like to say about the scenario given to me.The given scenario is about the villages of spectacular and Little Stanwell in Derbyshire Peak District. They are small communities which have about fifty houses each but they have lot of voluntary activities. Recently they gained wideband access to the internet. Now they planned to implement Parish plan in a way to develop specialized services. They formed some communities to organize these implementations. They dont bother about the logical and physical data model because they are too technical but committee members are non-technical so they need conceptual data model just. In those my scenario is to produce a plan for Stanwell Parish Register. This is a database which stores all information about the residents and the cares they many provide or avail.Coming to database design there are some standard tools for this purpose. They are ER, EER and use case diagram. In the remaining part of this report I am going to write about the office and importance of each of these standard designing tools in database design.Entity Relationship modelAs the name implies Entity Relationship Model is a diagram which shows the relationships between the entities involved in the business. An entity is a real world thing it may be a person or car or house etc. Relationship tells us how one or more entities are related to each other. ER model is a part of Conceptual data model. In the views of dickhead Pin-Shan Chen (1975) The Entity Relationship Model adopts the more natural view that the real world consists of entities and relationships. It incorporates some of the important semantic information about the real world. The model can achieve a high degree of data independence and is based on set theory and rel ation theory. In ER model entities are represented with rectangle boxes, attributes are represented with ovals and relationships are represented with rhombus type boxes. For the given scenario residents and assistance are the main entities. Following diagram will resolvely explain the ER model for given scenario.Figure 1 ER diagram for Stanwell Parish Register (It is just a part)From the above diagram it is clear that Resident and Assistance are the main entities. R_name and A_name are the attributes where as provides/avail tells us how those two entities are related. One to many and zero to many are the relations between resident and assistance. It means one resident can provide or avail zero or many assistances and one assistance can be provided or avail by one or many residents. There is nothing technical in this diagram but it represents all the business flow. So any non technical member can also understand the business flow by having a look at this diagram. As I said earlier h ere committee members are non technical so for any scenario ER diagram will help them to understand the flow of design.Enhanced Entity Relationship ModelThere is no prize money for guessing Enhanced Entity Relationship Model is the extension for ER model. Each model will have some limitations. In the same way ER model also has some limitations. In a way to overcome those limitations EER model was found. It is very difficult to represent complex applications through ER model and it is hard to represent the relationships which are more than binary. According to Connolly (2004) Semantic concepts are corporate into the original ER model and called the Enhanced Entity Relationship (EER) model. Examples of additional concept of EER model are called specialization/ generalization. Those concepts are also called as abstract concepts. In the words of Irwin Levinstein (2001) Specialization defines SETS of subclasses on a class. Each set called a specialization. Generalization unites several entities into a set of sub-classes, making a new class. This model flora mainly with super class and sub-class concepts as well as with is a kind of and is a part of relationships. To explain this model clearly I would like to give an example from the given scenario.Figure 2 Example for EER model from given scenarioThe above figure is just an example for the semantic concept specialization. From that diagram it is clear that permanent resident and contract resident are a kind of residents. All the rules applied for the resident are applied for those two also. This is is-a relationship example. If we consider assistance then shopping or teaching are a part of assistance.Use case modellingUse case modelling is one more standard tool in database design. The main components of use case modelling are use cases and actors. This model was invented by Ivar Jacobson in early 1990s. According to an Oracle white paper (2005) A use cases are fundamentally a text form and are used to delineate the functional requirements of a system, primarily as a scenario. The scenario describes how the system should respond to a request of a primary actor to deliver a proper(postnominal) goal of that actor. In the given scenario resident is an actor and providing or availing an assistance is a use case. The following diagram shows how use case modelling works in the given scenario.Figure 3 An example for use case modellingEach model stated above has advantages and disadvantages. So the choice of model is fully dependent on the type of scenario as well on the organization members and business requirements.Quality of a database designAs we all hold up database is an important asset for any application in the real world. So it is important for any developer to aim at efficient database design. Here the word fibre plays a vital role because by measuring the quality of a database one can say that the database design is efficient. With an immediate affect one unbelief will comes in to o ur minds is How can we measure the quality of a database design? There are many ways to measure the quality of a database design. Some authors followed some metrics and semantics to measure the quality of a database design. John A. Hoxmeier (1998) proposed a framework for database quality. He classified all the database quality factors into four categories. They are Process, Data, Model and Behaviour. Total Quality Management (TQM), Quality Function Deployment (QFD) and Capability Maturity Model (CMM) are used to measure the process quality. Data quality depends on the factors such as redundancy, integrity and age of the data. These two measurements and behaviour quality are not important here because I am asked to write about quality of a database design.In the words of John A. Hoxmeier (1998) Data quality is usually associated with the quality of the data values. However, even data that meets all other quality criteria is of little use if it is based on a deficient data model. It means Data model quality has the highest priority when comparing with other quality criteria. Let us consider an example, from the given scenario one resident can avail or provide zero or more assistances. If the developer put this as wrong then however the data, process and behaviour is good there is nothing use with that database. Check points in data mode quality are Representation (flexibility and Interpretability), Semantics (content, scope and understandability), Syntactic (presentation and documentation) and Rules (ease of use and normalization). Apart from all these points client creates boundaries and set rules for the application. So it is very important to follow them.Answer for the question Is a correct database design necessarily a quality design? Is no. Because even the quality of a database design is good if there are any mistakes with data model then it will be wrong. In the same way correct database design also not a quality one. maturement process of a quality app lication is not only depends on the type of application but also on the database design principles. Database design principles are applicable for all type of applications. But the choice is totally depends on the developers and users. In the given scenario it is not important to show all the models to the committee members only ER is sufficient. May be in other scenario EER is suitable.ConclusionProducing an efficient database design is the ultimate goal for any database developer. Stanwell Parish Plan is not an exceptional here. So they formed certain groups to implement their plan on the given scenarios. Here my task is to explain them about producing a good quality database design. First and important step for any application is to create a database design. In creating a database design there are some standard modelling tools such as ER, EER and use case modelling. Each model has its own advantages and disadvantages. Depending on the type of application database developer wants t o choose a particular model. Not only creating the database design is important but also maintaining the quality of a database design is important. I explained some quality criteria for this purpose. Finally it is a good idea for Stanwell Parish Plan to take the report from the different people for different scenarios. At the end of the day they will have many choices to pick up one.

The Medication Errors Generated By Nurses Nursing Essay

The medical examination specialty Errors Generated By Nurses Nursing EssayIn many cases, practice of medicine errors cause adverse events, and sometimes, the consequences are fatal. Many of these mistakes are avoidable if policies of the hospital governing medicinal drug government activitys are adhered to. In the U.S. today, most people use prescription medicine practice of medicines, over the counter drugs, or dietary supplements. Errors when prescribing or taking these medicinal drugs has been a problem for forbearings, insurance companies and the health distribute industry. The focus on medicament errors has stirred up rapid espousal of medication judicial system technologies such as the suspend-code medication garbage disposal (BCMA) system. Medication administration is an important treat task. Work overload, combined with change magnitude numbers of prescribed medications, puts nurses at risk of making serious errors. Medication errors are costly in terms of i ncreased hospital stays, resources consumed, patients harmed and lives lost. Mistakes also generate the potential for serious effects on the nurse involved, ranging from feelings of guilt and fear, to loss of clinical confidence, and disciplinary action as well as job loss. Medication errors happen in the hospital much more than are reported and their reasons are various including errors clinicians make in prescribing medications. A physician writes an order that sometimes contains instructions that if followed, will issuance in patients getting medications that are harmful to them. They may have had adverse reactions to such medications in the past or the drug may be contraindicated for the purpose for which they were ordered. This research paper will prove that the BCMA system is a reliable technology in reducing medication errors. On the different hand, critical stairs omitted by health care providers and nurses often contribute to more than half of the medication errors gener ated when using the BCMA system. Thus, health care providers and nurses adopt to be educated on patient and medication safety as well as the complete use of the BCMA system. A clinical policy on the use of the BCMA system will also be developed.For the purpose of research, the medication errors to be discussed will be restricted to the use of the BCMA system by nursing personnel. There are many regulatory guidelines for the administration of medications, but these policies are often ignored by nurses and other healthcare workers, and buns result in errors. In the hospitals where we attend our clinical rotations, such as Kaiser and San Francisco General Hospital, medications such as chemotherapy, insulin, narcotics, heparin and magnesium sulfate have been identified as high up risk medications. The nurse administering these drugs must have another licensed nurse cross check the order including the patients name and identification number (ID), r step to the foree, dosage and admin istration time for accuracy. The second nurse often appends his or her signature to the order without doing or completing the cross-check. Medication error is the inappropriate use of medication that can cause harm to patients. (See accessory A)Literature reviewResearch and Critique of literatureFranklin, OGrady, Donyai, Jacklin Barber (2007) are a group of pharmacists from the School of Pharmacy capital of the United Kingdom and the Department of Pharmacy Surrey, UK, who conducted a before and after consume of the BCMA system. They concluded that the closed-loop electronic and prescribing take out-code system cutd medication errors. Strengths of the study are that data were gathered with a comprehensive framework and the identification of prescribing error was noted using a validated method. One weakness is that the system was piloted on unitary ward. A mixed method study by Koppel, Wetterneck, Telles Karsh (2008) from the Center for Clinical Epidemiology and Bio-statistics and the Department of medicine identified fifteen types of BCMA workarounds. Workarounds such as omission of dish travel, steps performed out of sequence and unauthorized process steps. Some limitations in this study were that the nurses knew they were being watched using the BCMA and all possible workarounds were not included. However, the study suggests that the BCMA is beneficial in reducing medication error. Sakowski, Newman and Dozier (2008) found that medication errors identified by the BCMA system are benign and pose no harm to patients. A limitation of this study is that only errors detected by the BCMA were reviewed and errors did not contain the patients diagnosis. Cina, Fanikos, Mitton, McCrea Churchill (2006) are a group of pharmacists that include a medication safety officer and a director of pharmacy services at Brigham and Womens hospital (BWH) in Boston. The group studied errors generated in the medication repackaging center of BWH, in order to identify and imple ment improvements to reduce medication dispensing errors. Unfortunately, the study examined only one site and relied on human observers who may have staged to detect errors. See Appendix B correspond to the book To err is human building a safer health system medication errors frequently occur during the prescribing, dispensing and administration stages, and preventable adverse drug errors are a predateing cause of death in the U.S (Kohn, Corrigan Donaldson, 2000, p.26). The American Hospital Association found that over 33.6 million admissions in U.S. hospitals in 1997 alone, at least 44,000 to 98,000 died of medical error and another 7,000 deaths were due to medication errors (as cited in Kohn et al., 2000, p.26). In addition, Philips et al. noted that a review of some U.S. death certificates, revealed about 7391 deaths caused by medication errors in 1993 (as cited in Kohn et al., 2000, p.32). Researchers Kaushal, Bates, Franz, Soukup, and Rothschild (2007) conducted a statistic al analysis and noted that about 49.1% of medication errors were serious and 15% were life threatening. They also found that the cost of medication errors at the 735-bed Brigham and Womens Hospital is about $1.5 million per year and $1.48 million for a 20-bed tertiary care academy hospital (Kaushal et al., 2007). Fatal or serious medication errors result in additional lengths of stay in the hospital, thus adding to treatment costs. In order to reduce frequent errors, the BCMA was introduced to the health care system by the self-assurance for Healthcare Research and Quality and the Institute of Medicine (OMalley, 2008).Sakowski et al. (2008) have found that approximately 3.1% of drug errors are made during hospital stays in the U.S. This decision is astonishing in the sense that the hospital is where people turn to for medical help and not medical injury that can result in death. However, the adoption of the BCMA by most hospitals today, has helped reduce medication errors before th ey reach patients (Cochran, Jones, Brockman, Skinner Hicks, 2007). With the use of the BCMA, 37% of medication errors were detected by nurses during the dispensing phase and 27%, during the administration phase (Cochran et al., 2007). Furthermore, they noted that the implementation of the BCMA in a 240-bed regional hospital study prevented 1,300 medication errors for a period of eight months (Cochran et al., 2007). Some of these errors were interrupted by the BCMA when medications were going to be minded(p) prior to their specified time, or about to be wedded without a physicians order, or to be given to the wrong patient (Cochran et al., 2007). Due to heavy workloads, brisk shifts, error warnings and the bulky nature of the BCMA, nurses find ways to bypass the BCMA system in order to get through busy schedules. These shortcuts often antecede to errors in medication administration along with errors generated by the prescribing physician, as well as by the dispensing pharmacy. M edication administration is a composite plant system that requires coordination among physicians who order the medications, pharmacists who verify and dispense the drugs, and nurses who administer the medications to the patients.SummarySteps in medication administration are initiated when a drug is prescribed by a health care provider. The prescriber writes the patients name, date, medication name, dosage, route (e.g. by mouth), number of tablets/capsules to be dispensed, the prescribers signature, his/her medical license number and Drug Enforcement Administration number (DEA) (numbers appoint to health care providers used for prescribing pain medications). Medication errors occur at this stage and include reasons such as a privation of attention to detail, lack of communication, duplicate medication with the same name but different doses or an indecipherable prescription order (Benjamin, 2003). Benjamin (2003) also noted that 71% of medication errors are due to poor communicati on, which can lead to prescribing contraindicated medication for a patient He goes on to give the example of an 80-year old man who was given the pain medication Demerol despite a reported allergy to Demerol. After administration, the patient became unresponsive, had respiratory arrest and suffered hypoxic encephalopathy (lack of oxygen to the brain do brain damage) (Benjamin, 2003). This incident goes further to show how important it is for physicians to communicate and listen to patients and nurses concerns when prescribing medications. Below is a copy of a poorly written prescription by a healthcare provider. In this example there are 3 different types of medications prescribed for one patient. Although the handwriting is legible, ambiguous writing can lead to misinterpretation and further lead to medication error (Benjamin, 2003). See Appendix C.Steps taken to ensure safety standards include affixing a computer generated bar code on medication containers. Pharmacists are suppos ed to be the first line of defense in reducing errors however, pharmacies can contribute to medication errors as shown in the research by (Cina et al., 2006). The pharmacist or pharmacy technician prints and affixes bar codes on medications that are ready for administration. During this process, medication errors occur either due to the system of wrong bar codes, medications missing bar codes, misspelled medications or medications with two different bar codes (Cina et al., 2006). Furthermore, 59.7% of medication errors occur during the final stages of pharmacy repackaging system, a system of replacing commercial packaging for generic ones, due to incorrect lot numbers and NDCs (Cina et al., 2006). Another research by Cochran et al. 2007 found that medication errors frequently entailed mislabeled medications, medications without bar codes and medications with bar codes that would not scan. Therefore, pharmacists need to be more vigilant in checking for bar codes, lot numbers, corre ct NDCs, correct medication spellings and also verify illegible prescriptions in order to reduce chances of medication errors.Despite the adoption of the BCMA as a medication safety technology, research has shown that nurses still contribute to a bulk of medication errors. Koppel et al. (2008) have found that 32% to 60 % (adult pediatric patients) of medication errors occur during the medication administration stage, most of which are caused by nurses because they failed to use the BCMA system. Because medication errors are so prevalent at the administration stage, nurses are mandated to use the BCMA system and are also needful to abide by the medication administration guidelines step-by-step, through the final documentation stage. If a step of the medication administration process is missed, the likelihood for medication errors increases. A research by Franklin et al. (2007) confirmed that nurses fail to check patients IDs 80% of the time before giving medications and 16% of medi cations were given before scanning the patents ID band (Carayon et al.,2007). For example, wrong medications can be intercepted by a nurse if he/she compares the printed medication bar code to the information displayed on the BCMA system. In order to reinforce proper usage, monthly in-service (refresher course) may be required to educate nurses on medication administration as well as the importance of abiding by the hospital policy of medication administration.The alarm intemperate on the BCMA system also allows nurses to detect medication errors before they get to the patient. But research has shown that nurses often disable and ignore the alarm well-informed because they claim, the sound is annoying and weird (Carayon et al, 2007). Koppel et al. (2008) found that nurses overrode BCMA alerts for 4.2% of patients charted and for 10.3% of medications charted. Errors were generated because the BCMA alarm was disabled and nurses did not follow administration steps, thus giving medica tions without confirmation by the BCMA system. The BCMA needs to be furnish with a mechanism that would restrict nurses from bypassing any administration step and this would help to reduce medication error. Also, the BCMA alarms should be configured such that the correct administration steps must be taken before advancing to the next step.For the BCMA to work properly, its advised that it should be charged or plugged in when not in use since it is a mobile machine that is in constant use. Often times, nurses fail to charge the BCMA as advised and when the BCMA loses charge, it shuts down without warning which can lead to data loss (Parker Baldwin, 2008). Data loss causes frustration for nurses so they decide to skip the BCMA system during drug administration (Parker et al, 2008). When batteries fail, nurses had no immediate means to exchange them with charged battery. Use of the BCMA was suspended until the units were recharged (Parker et al., 2008). Since the BCMA system is used constantly for multiple patients, battery life can be preserved by getting a BCMA that uses removable batteries. A removable battery can last for twenty-four hours as well as making sure that there are particular(a) replacement batteries for the BCMA.The BCMA system requires lots of confirmatory steps and a personal log-in process by nurses before a medication is confirmed accurate for administration. Parker et al. (2008) found that nurses were dissatisfied with the log-in process because it requires much time to complete a single log-in. A single log-in process could take up to 2 minutes, consuming up to 48 minutes of nursing time waiting for computer access(Parker et al., 2008). Therefore, nurses cut corners in using the BCMA they decide to give the medication without using the BCMA and document the action at a later time. This can cause a nurse to administer the wrong medication and to the wrong patient. The BCMA process requires that nurses scan both, the medication and patien ts ID band in the patients room before administration. In many clinical facilities, the policy is for nurses to dispense the medications, one patient at a time. In fact, the rule is that the nurse, check the medication record of a patient against the patients profile in the pyxis (medication storage). If they match, the nurse will then pull out the medications for the particular patient and walk directly to the patients room with the medications and the BCMA system. In the patients room, the nurse scans and checks the medication and name against the patients ID band if they match, the medication is then administered and documented after administration. Nurses however, do not follow this simple rule in medication administration. The result of circumventing the rule is that nurses walk into a wrong patients room and administer the wrong medication. According to a research by Carayon et al. (2007), the correct sequence for medication administration is as follows See Appendix D. These s teps are critical in corroboratory that the right medication is given to the right patient. However, they found that nurses often do not follow the steps. For example, nurses were documenting medications before it was actually given to the patient. They check and obtain medication before scanning patients ID band (Carayon et al., 2007). To reduce the problem of workarounds, nurses who are caught with multiple medications and wristbands, need to be disciplined. And bar codes can be printed in bold so nurses can acknowledge them.The use of the BCMA requires complete attention in order to avoid mistakes. Patterson, Cook, and Render (2002) have found that nurses are often interrupted for one problem or another during medication administration. Below is a flow chart that shows the various instances when nurses are interrupted during medication administration process. See Appendix C. Medication administration is very critical and to reduce frequent interruptions, the nurse manager should make sure that a charge nurse (a nurse who supervises other nurses without having a patient) is assigned during every shift to help nurses with minor needs such as moving or walking a patient. Nurses should be given more training opportunity to better understand the use of the BCMA as well as its functions.ConclusionThe BCMA is still a challenge to health care workers on the other hand, it has helped to reduce medication errors since its adoption. Health care providers need to help reduce medication errors by putting patients safety first. Nursing staff need to be more cooperative and strictly follow the prescribed guidelines when using the BCMA system during medication administration.

Energy Efficient Building Design Strategies For Hot Climates Construction Essay

Energy Efficient twist Design Strategies For Hot Climates reflexion Es putThis research discusses goose egg efficient creation strategies of traditionalistic houses in Iraq ( impetuous-arid climate), climatic design techniques and potentials for re invigoratedable zip fastener systems that fecal matter be implemented in the contemporary residential design techniques in rank to offset the absence of produced energy ( receivable to current economic and political issues) and help decreasing demand for electricity, which is utilise extensively to overcome the indoor thermal dis puff during the harsh summer seasons. A comparison between traditional Baghdadi house (Hosh), which existed before the discovery of oil, and a contemporary house design option is to be made to evaluate the thermal performance of both options in this climatic zone in order to adapt more energy efficient design strategies and likewise to integrate features for sustainable construct design and potentials to implement renewable energy systems.A affectation modeling is to be used to conduct analysis of energy efficient design strategies, namely relating to construction envelope, size and direction, ventilation, shading elements, and using renewable energy systems in order to mystify recommendations that helps in consequential energy offset while preserving comfort.KeywordsIntroductionExamining the energy demand in such region, makes, with particular university extension to residential houses, atomic number 18 one of the to the highest degree significant energy-sensitive entities (Al-ajmi Hanby, 2008). It is stated that buildings consume over half of all electricity and one-third of inbred gas (Yilmaz, 2007). reducing of energy consumption in residential buildings is a major aim worldwide and is a particular challenge in this region for the reasons mentioned previously (Al-ajmi Hanby, 2008). Therefore, sustainable design strategies atomic number 18 of great importance nowada ys in order to reduce energy consumption in residential buildings.One may say that sustainability was already a driving force in the past, showing its validity in those days in different forms and techniques. Therefore, problems and precautions in design and social structure did not change fundamentally, although a lot of waxment was seen in materials and technology. Of course, these developments may obligate had some negative effects (Yilmaz, 2007).Energy efficient design strategies for traditional houses in such climate are significantly different from each other as it can be easily seen in the traditional design (Yilmaz, 2007). commentary of Problem AreaEnergy consumption is becoming more and more important in todays world because of a possible energy shortage in the future. Efficient use of energy has become a key issue for the roughly energy policies (Yilmaz, 2007).In regions where risque-arid climatic zone is prevailed, practically in Iraq, present economic and political circumstances have become the of import reasons that led to a significant energy shortage although Iraq has a spare operational competency of oil supply in comparison with other countries around the world.A significant need for new energy efficient design strategies and developed buildings construction standards in this stadium has become essential in order to offset the absence of produced energy and help decreasing demand for electricity, much of which is consumed in standard pressure conditioning systems, which is used extensively to overcome the indoor thermal discomfort during the harsh summer seasons (Al-ajmi Hanby, 2008).Conceptual FrameworkFigure (1) provides a diagram of the conceptual framework that has devised for this research.The proposed research study into traditional and contemporary building design systems will rely on an experimental research strategy in the incontrovertible system of inquiry (developed design strategies). The research will attempt to establ ish a comparison (Groat and Wang, 2002, P. 254) between a treatment (independent variable) and an outcome (dependent variable) by means of the valuation of measured results.Figure (1) Conceptual diagram of the research variables (Groat Wang, 2002)Research QuestionsDo traditional houses perform better than contemporary ones? Why?Is it feasible to use traditional design strategies in contemporary houses?How could we achieve a sustainable building design in such climatic zone?Do we need new or developed strategies in order to achieve sustainable building design in such climatic region?What if we integrate renewable energy systems into traditional house design?Project Goals and Specific ObjectivesThe purpose of this research is toMake a comparison and evaluation of thermal performance of residential houses (traditional vs. contemporary) in Iraq (hot-arid climate) in order to adapt more developed and energy efficient design strategies.Integrate new trends for sustainable design in res idential houses in this field of operation.Potentials to implement renewable energy systems.This research is achieved with the followingExtensive overview of the antecedent literature in the area of energy efficiency and thermal building performance in such climatic zone.Identify the just about effective strategy from the literature that can be applied in order to develop more energy efficient design strategies.Un-wrap issues of energy efficiency, building performance and sustainable design systems.Use a simulation modeling as a tactical tool to make comparison between contemporary and traditional building design systems and energy performance in order to investigate the thermal characteristics and energy savings for both building designs using different strategies and also potentials to integrate sustainable features using renewable energy system.Test outcome results and put out a research report accordingly which combines my encountering of the relevant theory and previous research with the results of my empirical research.Literature ReviewThe literature review is organise around the key concepts of significance of energy efficient design strategies, thermodynamics of hot-arid climates, Inventory of traditional design elements in hot-arid climate and energy simulation methods. These key concepts have led to the research questions and the proposed methodology for this research proposal. See figure1 for the map of literature reviewed.Figure () Map of beginnings reviewedFigure () Research Literature Review Diagrammatic (Groat Wang, 2002)Building Design StrategiesClimatic Building StrategiesResearch by Ochoa Capeluto (2008) states a quick review of design strategies for different climatic zones. This is necessary to examine when and how design strategies should be considered, particularly during design appendage. Climatic building strategies in hot climates differ from those of cold ones, For example, in cold climates arouse energy collection and s torage is essential, and ventilation moldiness be limited for the alike reasons. Short day term and low radiation levels in winter make maximum penetration of natural light to be desired.On the other hand, in hot climates commove must be excluded, the amount of relative humidity controlled, and the thermal volume simmer vote outed usually with natural ventilation during the darkness. Daylight penetration must be carefully managed using control devices (see figure 1) (as cited in Ochoa Capeluto, 2008, Building and Environment, P.1830).Figure (1) Building strategies for cold and hot climates (Ochoa Capeluto, 2008).Optimized Building EnvelopeA building envelope is a skin that separates between the interior and the exterior of a building. It serves as the outer shell to encourage the indoor environment as well as to facilitate its climate control (controlling high temperature transfer between building layers).The study by Danny Harvey (2009) reviews the literature concerning energy efficiency that can be achieved with optimized building envelope.According to Danny Harvey (2009), The effectiveness of the thermal envelope depends on(1) The insulation levels in the surrounds, ceiling, and other building parts(2) The thermal properties of windows and doors and(3) The rate of uncontrolled exchange of in spite of appearance and outside nervous strain which, in turn, depends in part on the publicize tightness of the envelope (infiltration/excitation) (Energy Efficiency, P. 141).Reducing the Cooling LoadEnergy conservation and climatic design techniques that can be implemented in residential houses in this area (hot-arid climate) are useful for reducing temperature reduction energy consumption (Al-Temeemi, 1995).Danny Harveys (2009) research fix the following Reducing the chilling load requires(1) Orienting a building to minimise the wall area facing directions that are most difficult to shade from the sun(2) Clustering buildings to provide some degree of self shading (as in m some(prenominal) traditional communities in hot climates)(3) Providing fixed or adjustable shading(4) development highly reflective building materials(5) Increasing insulation(6) Using windows that transmit a relatively clear fraction (as little at 25%) of the total (visible + invisible) incident solar energy while permitting a big fraction of the visible radiation to get in for daylighting purposes(7) Utilizing thermal mass to minimize day meter interior temperature peaks(8) Utilizing nighttime time ventilation to remove daytime heat and(9) Minimizing internal heat educes by using efficient lighting and appliances.The combination of external insulation, thermal mass, and night ventilation is particularly effective in hot-arid climates, as placing the insulation on the outside exposes the thermal mass to cool night strip while minimizing the inward penetration of daytime heat into the thermal mass (Energy Efficiency, P. 141).Passive cooling techniques By using the above measures to reduce the thermal load of the building, other techniques requires small inputs of mechanical energy to optimize passive cooling processes (Danny Harvey, 2009).Danny Harveys (2009) research discussed the following major passive cooling techniquesPassive ventilationPassive ventilation reduces the need for mechanical cooling by directly removing impregnable gentle wind when the incoming air is cooler than the outgoing air, reducing the perceived temperature due to the cooling effect of air motion and increasing the acceptable temperature through psychological adaptation when the occupants have control of operable windows.Passive ventilation requires a driving force, and an adequate number of openings, to produce airflow. It can be generate through pressure differences arising from inside-outside temperature differences or from wind.Design features, especially traditional, that give thermal driving forces and/or utilize wind effects include courtyards , atria, wind towers, solar chimneys, and operable windows. Passive ventilation not only reduces energy use, but can improve air quality and gives people what they generally want. In buildings with honorable thermal mass exposed to the interior air, passive ventilation can continue right through the night, sometimes more vigorously than during the day due to the greater temperature difference between the internal and external air. Night time ventilation, in turn, serves to reduce the cooling load by making use of cool ambient air to remove heat (as cited in Danny Harvey, 2009, Energy Efficiency, P.142).evaporative coolingDanny Harveys (2009) study further discussed the following in terms of producing evaporative cooling techniquesEvaporation of water cools the remaining liquid water and air that comes into reach out with it. The coldest temperature that can be achieved through evaporation is called the wet-bulb temperature and depends on the initial temperature and humidity (the h igher(prenominal) the initial humidity, the less evaporation and cooling that can occur). There are two methods of evaporative cooling the air supplied to buildings. In a direct evaporative cooler, water evaporates directly into the air stream to be cooled. In an indirect evaporative cooler, water evaporates into and cools a secondary air stream, which cools the supply air through a heat exchanger without adding moisture. By appropriately combining direct and indirect systems, evaporative cooling can provide comfortable temperature-humidity combinations most of the time in most parts of the world. Evaporative cooling is most effective in dry regions, but water may be a modification factor in such regions. However, arid regions tend to have a large diurnal temperature range, so thermal mass with external insulation and night ventilation can be used instead (Energy Efficiency, P.142).Influence of Energy Efficient Design Strategies on Design StagesThe architectural design process is i terative and moves from the abstract (definition of massing, orientation, and image) to the special(prenominal) (lighting control, mechanical ventilation type) (as cited in Ochoa Capeluto, 2008, Building and Environment, P.1830).At the design stage, key decisions taken by architects can significantly exercise potentials to optimize building efficiency. These include decisions affecting the selection of building components.According to Ochoa Capeluto (2008), As it advances and more specialists are called in to solve details, earlier decisions, which could have an enormous influence on the building performance, are expensive and harder if not impossible to change (Building and Environment, P.1830).Other influential factors unrelated to climatic strategies must be taken into account. For example, a certain orientation that is bad for energy consumption might define how well the building performs (Ochoa Capeluto, 2008). However, it would require an Integrated Design Process (IDP), in which the design process optimizes the building performance by involving all members of design-making team from the beginning.The importance of an Integrated Design Process (IDP) on building systems approachDanny Harveys (2009) study put up the followingThe systems approach requires an Integrated Design Process (IDP), in which the building performance is optimized through an iterative process that involves all members of the design team from the beginning. However, the unoriginal process of designing a building is a largely linear process, in which the architect makes a number of design decisions with little or no consideration of their energy implications and then passes on the design to the engineers, who are supposed to make the building habitable through mechanical systems (Energy Efficiency, P. 140).The steps in the most basic IDP are to consider building orientation, form, and thermal mass to specify a high-performance building envelope to maximize passive heating, cool ing, ventilation, and daylighting to base efficient systems to meet remaining loads to ensure that individual energy-using devices are as efficient as possible and properly sized to ensure the systems and devices are properly commissioned By focusing on building form and a high-performance envelope, heating, and cooling loads are minimized, daylighting opportunities are maximized, and mechanical systems can be greatly downsized (Danny Harvey, 2009).Thermodynamics of Hot-Arid ClimatesAny consideration to energy efficiency applications or design strategies in any climatic zone requires examining of thermodynamics and human comfort.In his school text Natural Energy and Vernacular Architecture Principles and Examples, With Reference to Hot Arid Climates, the author demonstrates properties of energy that must be considered in order to fully understand climatic phenomena. Heat, radiation, pressure, humidity, and wind, among other factors, interact mutually to establish microclimatic conditions appropriate to hot-arid climatic (Fathy, 1986).According to Fathy (1986), the following are some of these basic concepts applied to hot-arid climatesThermal adoptSolar radiation is the principal source of heat in hot-arid zones, and this heat can be transmitted during the day to the building interior in a number of ways. The most important is by conduction of the absorbed solar radiation through the walls or capital at a rate impelled by the thermal conductance (or thermal resistivity) of wall components. (The relationship involving the incoming and reflected solar radiation absorbed and re-emitted heat and heat gain is shown in figure 2 below for the case of a typical white painted surface).Figure (2) (Fathy, 1986)Heat gain can also be caused by ventilation. The rate of gain is dependent on the ventilation rate. Ventilation heat gain can be avoided by restricting the size of openings, especially during the heat of the day. The other sources of heat gain are the inhabi tants of the building themselves and household equipment such as electric lights and appliances. These sources, unlike the solar radiation, can contribute heat even at night (see figure 3) (Fathy, 1986).Figure (3) Modes of heat transfer (Fathy, 1986)Thermal lossHeat is alienated by conduction through the walls, by exactly the same process that it is gained from the direct solar radiation once it has been absorbed by the surface or through the roof by a combination of convection and conduction. Ventilation is also another mode of heat loss. Evaporation from the surface of the building or from objects within the interior can produce a cooling effect on the building which acts as a source of heat loss. In hot arid climates, this can be a particularly effective cooling machine since the rate of evaporation in dry air is very high. Figure 3 also shows the modes of heat loss (Fathy, 1986).Cooling by evaporationEvaporative cooling is used for cooling in hot dry areas (such as in Iraq, wh ere the people place against the windows panels of dried desert plants, which are kept moist by water dripping from perforated pipes positioned above them) (Fathy, 1986).Dynamic thermal equilibriumThe heat gained by the building can be expected to be balanced by the heat lost and an internal temperature distribution thus established. These temperatures are dependent on the outside temperature and the ratio of the heat gained to the heat lost and can be adjusted by regulating the sources of heat gain and loss. Before examining the systems and devices that have been developed to do this in the hot arid zones, it is starting signal necessary to have an idea of the heat-regulating mechanism of the human bole and the microclimatic conditions for human comfort.Table (1) Heat gain and loss processes for the human body (Fathy, 1986).Mechanismadd-on ProcessLoss ProcessMetabolismBasal heat productionDigestionActivityMuscle tensing and shivering in response to coldRadiationFrom solar radiati on-direct and reflectedTo surrounding airFrom radiation by radiatorsConductionFrom air above skin temperature (increased by air movement)To air below skin temperatureFrom warmer bodies in contactTo cooler bodies in contactEvaporationFrom respiratory tractFrom skin covered with perspiration or applied waterConditions of human comfortA convenient standard for thermal comfort is required. Analysis shows that a variety of factors can be involved in situations of discomfort. For example, temperature alone does not chequer discomfort. In Athens, 32 C is quite bearable, but it is generally intolerable in Bahrain. The difference is due entirely to the relative humidity of the atmosphere. In Bahrain the air is very humid and perspiration evaporates slowly, decreasing the bodys ability to lose heat. In Athens, with its dry air, the evaporation rate is high and perspiration evaporates quickly lowering body temperature. The factors that have been identified as standard for thermal comfort with in buildings are air temperature, air humidity, rate of air movement, level of radiation, and rate of heat production by the bodies of people in the building 4.Inventory of design elements for traditional housing design in hot-arid climatesBuilding materialsThe materials surrounding the occupants of a building are of prime importance for protection against heat and cold. Considering an external wall exposed to a high outside air temperature and a lower inside air temperature (see figure 4), the rate of heat flow transmitted through the wall from the outside air to the inside air is proportional to the air temperature difference, area of the wall, and rate of global heat transmittance that can be determined from an analysis of the components of the total opposite to heat flow. The total resistance is composed of the resistance to heat flow through the material, the interfacial resistance at the external surface, and the interfacial resistance at the internal surfaces. Since the inte rfacial resistances are determined in the main by temperature conditions over which the builder has little control, his principal effect on the heat transmittance is on changing the resistance to heat flow through the wall material (Fathy, 1986).Figure (4) (Fathy, 1986)Table 2 lists the thicknesses of walls composed of various construction materials needed to achieve coefficients of approximately 1.1 kcal/hmC. The mud brick is most appropriate for achieving thermal comfort in addition to being widely available to all segments of the population (Fathy, 1986).Table (2) Thicknesses of walls of different material (Fathy, 1986)Wall sensibleWall ThicknessThermal Transmittance(in m)(in in)(in kcal/ hmC)Hollow brick block0.30121.10Double-wall brick with holes and 8-cm cavity2 x 0.122 x 4.71.12Brick wall with holes0.38151.03Sand-lime brick0.51201.25Hollow block sand-lime brick0.51201.16Lime0.51201.10-1.35Concrete1.00391.20OrientationIn hot climates, the sun is the major source of heat. The position of the sun must be determined for all hours of the day at all seasons as well as the direction of the prevailing winds, especially during the hot season. In addition, for an ensemble of buildings forming a sector, there will be reflection from adjacent buildings and wind screening by clusters of buildings, which contribute to a specific microclimate for each location in the sector. Wind movement and humidity also are important and should be considered simultaneously with the direct and indirect effects of the sun. The main objective is to establish the optimum orientation with regard to the sun and the prevailing wind (Fathy, 1986).ShadingGenerally, a building with a facade opening to the westside is the worst case encountered in hot-arid climate, owing to the heat gain of the surrounding environment during the day and the angle of altitude, which allows the suns rays to penetrate into the interior.OpeningsWindow openings normally serve ternion functions to let in direct and indirect sunlight, to let in air, and to provide a view (Fathy, 1986).The venetian blindOne device which can be added directly to the window is the venetian blind. This blind is made of small slats, about 4-5 cm wide, closely set in a wooden frame at an angle that will intercept the suns rays. The slats are often movable so the angle can be changed. This feature of adjustability renders venetian blinds very useful in regulating solar radiation and wind flow into rooms. Using the venetian blind, the suns rays can be blocked out without obstructing the breeze, which generally blows from the northwest in most hot arid areas like Iraq. As shown in figure 5a, changing the position of the blind alternatively by to block the direct sunlight, the wind is redirected uselessly over the heads of the occupants, as figure 5b illustrates. Also, if the slats are made of metal, they then absorb some incoming radiation and reradiate it into the room as heat (Fathy, 1986).Figure (5) (Fathy, 1986 )The Shanshool or MashrabiyaThis was a cantilevered space with a lattice opening, where small water jars were placed to be cooled by the evaporation effect as air moved through the opening. The name is used for an opening with a wooden lattice screen composed of small wooden balusters that are circular in component and arranged at specific regular intervals. The shanshool has five functions. These functions involve (1) controlling the passage of light, (2) controlling the air flow, (3) reducing the temperature of the air current, (4) increasing the humidity of the air current, and (5) ensuring privacy. Its cooling and humidifying functions are closely related. All organic fibers, such as the wood of a shanshool readily absorb, retain, and release considerable quantities of water. Wind passing through the interstices of the porous-wooden shanshool will give up some of its humidity to the wooden balusters if they are cool, as at night. When the shanshool is directly heated by sunligh t, this humidity is released to any air that may be flowing through the interstices. This technique can be used to increase the humidity of dry air in the heat of the day, cooling and humidifying the air at a time when most needed. The balusters and interstices of the shanshool have optimal absolute and relative sizes that are based on the area of the surfaces exposed to the air and the rate at which the air passes through.In addition to these physical effects, the shanshool serves an important social function it ensures privacy from the outside for the inhabitants while at the same time allowing them to view the outside through the screen (Fathy, 1986).Table (3) Summary of architectural elements of traditional building in Iraq (hot-arid climate), as they have been cat valium from the 13th to the end of the 19th century.

The high value of privacy demanded, that no house was higher than the others, so that nobody was able to human face down on his neighbors roof.kabishkan The Penthouse, from where one is able to control all the house. Often those rooms have been placed like eyries in all four corners of the inner courtyard.The roofIf the outdoor air temperature is higher than the indoor temperature, the outer surface of the roof exposed to the sun is heated as it absorbs radiation, and, being in contact with the outside hot air, also is heated by conduction. The roof then transmits this heat to the inner surface, where it raises the temperature of the air in contact with it by conduction. At the same time, it radiates heat that is absorbed by people and objects indoors, thereby affecting thermal comfort. In hot arid countries, since the air temperature drops considerably during the night, the inhabitants have arranged the roof architecturally into loggias or open galleries and lightweight roof covers. These loggias and roof covers have the double function of shading the roof during the day and providing physiologically comfortable financial support and sleeping spaces at night (Fathy, 1986).Figure (6) Different types of roofing in hot-arid climates (Fathy, 1986)The wind-escapeThe technique of using the suction caused by low air-pressure zones to generate steady air movement indoors is used in the design of the wind-escape. The funnel and side tube used to illustrate the Bernoulli effect or Venturi action (see figure 7) are transposed into the structural elements of an architectural design in order to accelerate air movement and to create drafts in places with no exposure to the outside, such as basements in Iraq. This concept can be applied more advantageously in designs for use above ground. The wind-escape can accelerate effective ventilation and air circulation when used with other devices for air movement such as windows, doors, and the malqaf or wind-catch (Fathy, 1986).Figure (7) Bernoulli Effect (Fathy, 1986)The malgafIn hot arid zones, a difficulty is found in combining t he three functions of the ordinary window light, ventilation, and view. Therefore, it is necessary to satisfy the three functions ascribed to the window separately. To satisfy the need for ventilation alone, the malqaf or wind-catch was invented. This device is a shaft rising high above the building with an opening facing the prevailing wind. It traps the wind from high above the building where it is cooler and stronger, and channels it down into the interior of the building. The malqaf thus dispenses with the need for ordinary windows to ensure ventilation and air movement. The malqaf is also useful in reducing the sand and dust so rife in the winds of hot arid regions. The wind it captures above the building contains less solid material than the wind at lower heights, and much of the sand which does enter is dumped at the bottom of the shaft. In the areas of An-Najf and Al-Kufa in Iraq, where air temperature is very high in summer, people live in basements ventilated by small hol es in the ceiling and a malqaf with a very small inlet. Figure 8 shows plans and the section of a residence with a basement from this region. However, as the airflow is small and the air circulation is insufficient, this design is unhealthy and a possible cause of lung diseases. In some designs, the drafts from the malqaf outlet are cooled by passing over water in the basement.Figure (8) The Malgaf (Fathy, 1986)The Bdgir-sirdabIn Iraq (hot-arid climate)and the countries of the Gulf, a specific type of malqaf called the bdgir was developed.

The Criticisms of Kohlbergs Moral Development Stages Essay -- Moral D

The Criticisms of Kohlbergs Moral Development StagesPart OneThe criticisms of Kohlbergs honorable development maps seem to center around three major points, his research methods, the regression of stage four, and finally his goals.The first criticism that I would like to address is that of his research methods. Kohlberg is often criticized for not only his subject selection, but also the methods by which he tries to extricate data from those subjects. His initial study consisted of school boys from a private institution in Chicago. The problem with this is fairly obvious, that this does not represent a world-shattering portion of the population to allow for generalized conclusions. In other words, how can we test some boys from Chicago and ascertain that this is how all people develop planetary?I believe that the answer to this criticism comes from the theory that it relates to. Kohlbergs moral development schema is highly dependent upon the idea that there are fundamental truths that cannot be dismissed. These ideas are in the ether, wound into the very fabric that constructs human nature. Granted, his descriptions of the various stages also seem very dependent upon the surroundings and social institutions that an various(prenominal) would be subjected to. Yet these institutions would be have to be built upon people, all of whom would share these ideological truths. It seems fairly obvious that all people have undisputable needs, survival and some group membership. Kohlbergs stages are merely methods by which one could fulfill these needs. For instance, Spartan societies were adamant about maintaining the purity and strength of the civilization. Citizens saw no wrong in exposing a sick or lame baby to the elements so that it might die. Surely an act of cruelty today, but in that society, a necessary evil The prosperity and wealth of the whole was of greater importance than that of the individual.In addition to these justifications, additional research su bstantiated Kohlbergs claims. Different subjects were tested, from all ages and regions, and the same conclusions were drawn from the data. presume that these conclusions are correct, and the data leads to the same interpretation, is there any other possibility? This argument seems most impressive, especially considering the differences between people that are evident in everyday life. Similarities ... ...o a small compromise to fit their needs. In conclusion, it seems that there is definitely a way to combine the Kohlberg justice group and the Gilligan caring theme of moral development. Mr. Kohlberg provides a method to police a society that does not include 100 percent utopian citizens. Ms. Gilligan gives us the ability to relate to to each one and every person, as a person. She indicates ways that we can identify with their perspectives, understand their needs, and compromise. Although the real world seems infinitely more complex than either of these models, they bear a frigh tening resemblance to real societies and real people. Maybe someday, a perfect model will be constructed, judged by a perfect path of moral development. Until then, I hope that I have found a good combination of these two ideas. One last side note I conjecture I could spend weeks typing a paper on this subject. There are thousands of facets of each system that could fit into the others potential flaws. However, I think Ive been ho-hum enough as it is. I have tried to make my points as succinct and reasonable as possible, but without sacrificing exactly what I wanted to say. give thanks you for your patience.

Analysis of McDonald’s Corporation Advertising :: Advertising

Advertising generally tries to sell the things that consumers want even if they should not wish for them. Adverting things that consumers do not yearn for is not impelling use of the advertisers money. A majority of what advertisers sell consists of customer items like food, clothing, cars and services-- things that people desire to have. On the other hand it is believed by many advertising experts that the greatest influence in advertising happens in choosing a brand at the point of sale. Advertising appeals to consumers through common images the logo utilize is well-designed and there is a clear separation of art from commerce. Advertisers use these iconic images to appeal to consumers since they symbolize or stand directly for something. The image for MacDonalds symbolizes its non-conventionality. wherefore advertisers use these images to communicate much more than words, since they seem to convey the message without too much effort. check to McDonalds website, their missio n statement is to be our customers popular place and way to eat. Our worldwide operations have been aligned around a global strategy called the Plan to win centering on the 5 basics of an exceptional customer experience People, Products, Place, Price and Promotion. We are committed to improving our operations and enhancing our customers experience. (http//www.aboutmcdonalds.com/mcd)For decades, Macdonalds has maintained a broad advertising campaign. In addition to the media, the company makes considerable use of signage and billboards, sporting events and coolers of drinks with their logo for all kinds of events. The company has used twenty-three diverse slogans in United States for advertising. At the very(prenominal) time the company has few other slogans for the selected countries and regions.In the case of McDonalds advertising the texts used are effective. They have contributed in attracting targeted clients to the company. The wordings are aesthetically pleasing and succe ssful at getting the consumers to buy the product.

Cloning: The Double-Edged Sword :: Biology

Cloning The Double-Edged SwordSuch a furore was created when the birth of chick the sheep the first successfully cloned mammal, was announced to the world in 1997, that the scientific community was gasping for air. Time and space seemed to have come to a virtual stand fluid as scientists vigorously, not to mention obsessively, hypothesized the cosmic future potential of Dr. Wilmuts teams revolutionary breakthrough in the dynamic realm of science. The euphoria of the moment, it seems, took some time to settle out front scientists began to unravel the possible detrimental ramifications of the discovery. Have Dr. Wilmut and team then generated a scientific miracle on one hand, while opening a Pandoras box on the other? It is difficult to dispute the fact that the successful cloning of Dolly has far-reaching applications in the twin fields of biotechnology and bioengineering. The advanced genetic reprogramming techniques employed to excogitate the clone have opened the door to a mult itude of potential avenues for application genetic engineering of organs for transplant purposes, xenotransplantation, cell therapy for illnesses such as Leukaemia, shaking palsy disease and diabetes, therapeutic cloning (the notion of growing tissue for patients that is genetically identical to their own, for example neural cells could be made for people with Parkinsons disease, new muscle for those with ailing hearts and, later, perhaps tear down whole organs might be grown, all free from the threat of tissue rejection), and even in curtailing the extinction of endangered animal species, just to name a few.While the advantages of nuclear transfer and genetic reprogramming seem manifold, the cloning and manufacture of transgenic life forms for search purposes, and not to mention the prospect of cloning humans, unearths countless compelling ethical questions which can, in my opinion, under no circumstances be satisfactorily answered. Here atomic number 18 a few to whet your appe tite- Do we humans have the moral right to play God? What would happen to animals (or humans) cloned unsuccessfully with deformities, since the technology and its complementary knowledge are still embryonic and in their primacy? How would we ascribe an identity to a human clone? Since there is no powerful and effective international regulation on the exercising of this technology in place today, how can we know for sure it is not being misused?
