What Is a Hero Essay Example for Free

What Is a Hero EssayWhat is a hero? To me a hero is not fewbody with the ability to fly, run fast, bench over a 1000, shoot lasers off of their eyes, fart fire balls, pee lava, or sway other masss minds. A hero is just an average man who fights to solve a common problem in todays society. A hero is a random citizen that rises to the a occasion and performs an action of superhero proportions. A hero is somebody as average as you and me that sees a problem and takes it upon themselves to fix it. There be many examples of heroes in our modern day world. Some heroes are the brave, courageous, and valiant men and women that serve in our military. These are people that are just like you and I. They do not meet any extraordinary superpowers besides an unwavering sense of duty towards this country and the people that hold up it.They travel across oceans and leave their friends and family behind so that they house fight to defend people that they dont even know and to secure the life style that so many of us take for granted. Some, even make the ultimate sacrifice their lives. Another common place to find a hero is in a police officer. These heroes are very similar to a soldier except that they fight their battles in the very streets that we call home and instead of fleck against other countries they fight against the very people that call this glorious country home. They sit in a smelly car for entire days staking out criminals to secure our welfare and our security.They put their lives on the line to make sure that the scumbags that seek to destroy this country are off the streets. These men (or women) also miss superhuman abilities. The only thing that they have is a sense of duty towards their country. The most common place to find a hero is also some of the places that you go to every day. One of these places would be at the grocery store. For example if you witness somebody holding the door for another then congratulations you have just hearted a hero at action.Another common place to watch a hero in action is on a street. If you watch a strapping young man help a helpless elderly women across the street then you have witnessed another act of heroism. Heroes are just common people that have the courage to solve a problem that they see in todays community. Heroes are not rare. They can be found almost everywhere you look. They are at places that you go too every day. Heroes can also be found in places that you do not travel very often. They can be found in the Armed Forces as well in the Police Department. But it does not remove acts of epic proportion to make you ahero. Small acts of unnoticed kindness is what I think really makes you a hero.

Education in Bolivia for the past 50 years Essay Example for Free

Education in Bolivia for the past 50 years EssayIn the year 1989, education in Bolivia was not considered as a right by many people. However, it was observed as a doer to control the lives of the masses by the ruling sector. The government restricted the wash up of funds to education because it gave more attention in other branches of the society. As a result, the illiteracy rate was very high. A country which has 13-14% illiteracy rate, Bolivia is regarded as the worst in the South Americas. The Bolivian government allocates 23% of its yearly budget to education which is actually the highest percentage in South American countries notwithstanding of its small budget. However, this did not help improve the literacy level of the country as a whole. According to the Bolivian National Statistics Institute in 2002, the rate of exacting literacy level is about 20%, functional literacy rate is about 35%, with totality of 55% only. There are about 11. 8% literacy rate in men were pr oven and this attachs to a relatively high 27. 7% for women (Carlos Santander-Maturana, 2007). Nowadays, the absentee rate is very high learner for children in the primary school from six to viii years. It is comparably lower on children aged nine, but increases significantly when on children aged 12 (Santander-Maturana, C. 2007).A very familiar explanation for this growing quandary is that the majority poor families, which comprise the leading portion in the Bolivian people, force their kids to stop from going to school in order to help their parents increase the family income. Similar thing is true to the other students who are in the secondary and tertiary level as is confirmed in Country Studies (2007) just 1/3 of the first graders completed the 5th grade, 20% started secondary school, 5% began their postsecondary studies, and just 1% received a university degree. Dropout rates were higher among girls and rural children.Only about 40% of rural youngsters continued their educa tion beyond the third grade (Country Studies, 2007). This astounding percentage is the worst among the South American countries and the government is immediately trying its best in combating this central problem in education. As years go by, parents of poor families started seeing education as a means to save them and their future generation from poverty. But as a family strives hard for survival, problems will always remain as problems no matter how they manage to calve them. The current economic condition of the family is one of the many causes of their being illiterate.As of now, the literacy condition is getting more and more improved because people are remunerative much attention in education more than they did before. The government is also in support of the projects to make education better. Many programs are now located out and are being implemented to secure the future of the country. The Bolivian style of education compared side by side with the United States is quite convertible in a few ways. As what is stated in Encyclopedia Britannica (2007) Primary education for children 6 to 13 years of age is free and officially compulsory, although school attendance is difficult to enforce in some areas.Secondary education, lasting up to 4 years, is not compulsory. Most education is state-supported, but privy institutions are permitted (Encyclopedia Britannica, 2007). Education in the United States is funded mainly by the government in three levels federal, state, and local. Primary education, which starts from 5-6 years old and secondary education are both compulsory. College education is still an option because there are still vocational and technical courses being offered by the state. Reading literacy rate in the US is as high as 98% being recognized as one of the best reading literacy all over the world.

Decentralized Approach for Achieving Seamlessness

Decentralized woo for Achieving SeamlessnessCONCLUSION AND FUTURE WORKThesis OutcomeThe major matter of this research effort is to analyse the feasibility and benefits of achieving broadloomness with the proposed decentralized show up augmenting the conventional centralized approach for miscellaneous net chokes. In lieu of this, the outcomes get tod includeA crossing Approach (Linux Kernel Module and SCTP) to decrease the latency during Vertical Handoff process and IP mobility to achieve seamless continuity.Location Awareness in Hybrid Approach to reduce the triggering of unnecessary handoffs during vertical handoff that result in performance degradation.Contributions of the Present WorkIn this thesis, several aspects and approaches for seamless continuity are discussed. The major contributions of the work carried out in this thesis areDifferent approaches to achieve seamless continuity in heterogeneous networking milieu.A brief review on the blossom forth issues and challen ges related to seamless continuity.Design and development of daemon based decentralized approach for intranet environment.Design and development of an efficient and fast manner known as kernel based decentralized approach for improving the latency during handoffs.Development of Stream Control Transmission Protocol (SCTP) approach for addressing dynamic address reconfigu proportionalityn in heterogeneous environment.Design and development of a novel hybrid method using the combination of SCTP and kernel module.Development of a position aware method to incorporate into the hybrid approach for heterogeneous networks.Solution OverviewThe proposed solution is a hybrid approach to achieve seamless session continuity in heterogeneous networks. This approach is completely decentralized complementing the centralized approach which is completely based on server agents. It can be applied to both intra and Internet environment without any changes to the network layer. To prove this approach fo r seamlessness, testing was done on three network interfaces Ethernet (eth), WLAN (wlan), WCDMA (wcdma).For IntranetA vertical handoff daemon was developed to achieve seamlessness oer heterogeneous networks. This daemon application runs as a background process at the drug user space and it in addition takes care of the handoff process amongst various radio interfaces. Firstly, this proposed daemon continuously polls for the registered interfaces and then checks the status (live or dead) of these devices. Later, it also updates the status to the network layer of the protocol stack to life the service continuing between the mobile device and the server. The designed architecture is well suited for all the IP based multimedia applications but discharge only in intranet environment. IP mobility is an issue which has to be still addressed which can non be solved in this approach.For InternetTo achieve seamless continuity over heterogeneous networks, this proposed solution is a comb ination of Stream Control Transmission Protocol (SCTP) and Linux kernel module. This kernel module gets registered with the Linux kernel and updates the status of various interfaces by signalling the SCTP application running at the user level. This SCTP application allow for then accomplish the handoff process between various network interfaces.The reason behind this approach is SCTP has an advantage of IP address reconfiguration which solves the IP mobility issue and Kernel module has an advantage of latency. This accomplishes the handoff process in a faster and elegant fashion. But this will non solve the problem of unnecessary triggering of handoffs. In this regard the following handoff decision process was integrated into hybrid approach to improve performance musical composition achieving seamlessness.Location based Handoff DecisionThis proposed algorithm is completely based on location based information. This is a research effort to study the feasibility of location based s olution which consists of combining the conventional handoff decision with a location based military rating mechanism. This mechanism relies on positioning method for obtaining mobile user position fixes. Once the users location, speed and direction are calculated, the evaluation mechanism will predict the users path. It will then decide whether the user will remain in the same network coverage area for necessary duration to result in performance improvement. If not, this proposed evaluation method will notify the mobile device to trigger a handoff. The knowledge on users location, speed and direction is necessary to go along inefficient and unnecessary handoffs.ConclusionIn this research effort, a seamless vertical handoff system across heterogeneous networks is presented. It is implemented in current Linux operational system. In the proposed system, the handoff latency is much shorter than other current systems focusing on the issue of vertical handoff. Different from other vert ical handoff systems, handoff agents or servers are not required in this system. Only with the mobile host itself, the vertical handoff can be realized. Moreover, the overhead during handoff is also quite low. The system is evaluated through a serial publication of experiments. The experimental results demonstrated the handoff is handled in a fast and elegant manner.The proposed system is tested in the real-world analyses. The experiments were conducted under different environments and evaluated with various multimedia applications. This work is not only for home network solution but it is extended to an Internet solution. Moreover, prior to triggering handoff, the algorithms ability to predict user direction, speed and chew out to WLAN coverage area allowed it to provide an observable benefit both on users perspective and also on networks perspective. This location based evaluation of the algorithm helped to not only prevent the occurrence of unnecessary handoffs which would resul t in performance degradation but also reduce wastage of resources.The novel hybrid decentralized approach based on location awareness presented in this work handled the issues of latency, dynamic address reconfiguration and unnecessary triggering of handoffs for seamless continuity in heterogeneous networks.Future WorkKeeping in view the wide proliferation of heterogeneous networks and soaring level of interworking required for next extension mobile users, the scope of the future work can be more focussed on pursuing open challenges such as battery ability consumption, Quality of Service (QoS) and security for effective ubiquitous experience and seamless continuity.Battery power consumption of the mobile client is a significant meter for handoff. Whenever the battery power drops to particular threshold, the mobile client should immediately shift to lower power demand network interface.As the demand for multimedia applications increases in that respect is a need to guarantee QoS such as high available bandwidth, Bit Error Rate (BER), network load balancing, Signal to Noise ratio (SNR) and so on.Security is another important criterion which needs to be addressed. Hence, when handoff data is exchanged between devices it is always preferable to have network with high level of encryption.In this research effort, some work was done on best Access Point selection algorithm. With the enormous increase of WLAN APs everywhere, there is a need to look at new approaches to select the best AP among multiple APs for achieving horizontal handoffs.

Stop or go sampling technique prohibits extravagant sampling of an attri hardlye.The Stop and go statistical sampling technique in a scenario where it is believed or perceived that relatively few errors depart be exposed, so there is point in wasting over sampling of an attribute.Use of statistical sample for tape library inventory is an example of ____ type of sampling technique.VariableSubstantiveComplianceStop or goAns. B storyThis is an example of substantive sampling whi ch confirms the integrity of a process. This stress go out determine whether tape library records atomic number 18 stated in a congeal manner.What is the major benefit of riskiness of exposure based canvass planning come near?Planning scheduling in advance over monthsStaff exposure to varied technologiesResources eitherocation to areas of top concernBudget requirements are met by visit moduleAns. C expositionThe physical object of risk based analyze preliminary is focus on areas where risk is high. Various scheduling methods are utilize to prepare audit schedules and it does non come under risk based climax. It besides does non relate to budget requirements met by staff and number of audits performed in a splitn year.Examples of substantive sampling technique includeReview of password history reportsApproval for configuration parameters changesTape library inventory verificatory list of exception reportsAns. C descriptionTape library inventory is an example of su bstantive sampling as it confirms the integrity of a process associated with find out whether tape records are stated in a correct manner. All others are example of compliance sampling as they determine whether the process in practice is inline with the established policies and procedures.The characteristic of an audit charter isIs dynamic is nature and keeps changing frequently as the technology changesIt contains the objectives of audit, maintenance and criticism of internal records by delegated authorityDetailed audit proceduresOverall scope, ownership and responsibility of audit functionAns. D storyAudit charter states issuement objectives, scope, ownership and relegation of responsibility of audit function. It should not change frequently and approved by higher management. Also it does not contain detail audit procedures.The attendant actions and finalitys pretend the ___ type of risk in a major manner.InherentDetectionControlBusinessAns. BExplanationAuditor selection / decisions during the audit process find direct impact on detection risks, such as enough number of samples not taken into make doation etc. Company actions manage the control risks and business and inherent risks are also not impacted by attender.Particular threat to overall business risk can be articulated in terms ofLikelihood and magnitude of impact , where threat successfully exploited a vulnerabilityMagnitude of impact, where source of threat successfully exploited a vulnerabilityProbability of a hurln source of threat exploiting a vulnerabilityRisk estimate team group decisionAns. AExplanationThe cream A addresses both likelihood and magnitude of impact and measures risk to an asset in better(p) manner. Choice B doesnt consider the magnitude of doable damage to an asset. Choice C dont consider the possibility of damage due to source threat exploiting a vulnerability and choice D is an arbitrary method of ascertain risk and it is not a scientific risk management appr oach.Risk management approach over baseline approach in reading security management gives a major advantage in terms ofOver justification of information assetsBase level protection to all assets irrespective of asset valueAdequate protection applied to all information assetsEqual level of protection for all information assetsAns. CExplanationBaseline approach applies a standard set of protection to all information assets whereas the risk management based approach determines the level of protection to be applied depending on a given level of risk. This saves the costs incurred on overprotection of an information asset. In baseline approach equal level of protection is applied for all information assets irrespective of asset value so as a result around assets could be under protective and some could be overprotective.Which interrogatory method is some effective when doing the compliance testing?Attribute samplingVariable samplingStratified mean per unit inconsistency estimationAns . AExplanationChoice A is book in this scenario. As attribute sampling model estimate the tempo of occurrence of a specific quality in a population to confirm whether quality is present in compliance testing. The other means of sampling are used in substantive testing where details and quantity testing is done.Why email is considered a useful source of tell in litigation in IS audit process?Wide use of email arrangements in enterprises as medium of colloquyAccess control mechanisms to establish email communication righteousnessBackup and archiving of information flowing through email systemsData classification guidelines dictating information flow via email systemsAns. CExplanationOption C is most appropriate as archived/ backed up email files, may contain rolls which have been deleted and could be recovered. Access controls besides establish accountability but dont give evidence of the email. Data classification standardizes what to be communicated by email but dont provi de information privationed for litigation process.A post implementation review of an screening is scheduled by IS auditor. What could be the affirmable situation which can hamper the independent assessment of IS auditor.Involved in the development of specific application and implemented specific functionality / controlIntegrated an embedded audit module in the application for auditing purposeWas member of application system project team but not wantd at operational levelGiven advice on considering best practices while system was in development stageAns. AExplanationChoice A is most appropriate in this scenario because the auditor independence is impaired in case he was involved actively during the development, encyclopaedism and implementation of the new application. Choice B and C dont hamper auditor independence. And Choice D is not correct as auditor independence is not hampered by given advice on best known practices.What is the benefit of continuous audit approachCollectio n of evidence is not required on system reliability during the processing stageReview and follow up on all information bundle upedImprovement in overall security in clipping sharing environment where gigantic number of proceeding processedNo dependency on complexity of organizations systemsAns. CExplanationChoice C is most appropriate w.r.t to continuous audit process major benefit as overall security is improved in time sharing environments where gargantuan number of transactions is processed but leaving insufficient trail of papers. Choice A is not correct as auditor need to collect evidence while processing is ON. Choice B is also not correct in this case as auditor does review and follows up on errors and material deficiency. Choice D is also incorrect as complexity of organization systems determines the use of continuous audit process technique.The objective of enabling audit trail isBetter response time for usersInstitute Accountability of processed transactionsImproving o perational energy of systemsBetter tracking of transactions to give useful information to auditorsAns. BExplanationChoice B is most appropriate in this scenario as accountability and responsibility can be established for processed transactions and tracing could be done end to end. Enabling audit trail dont improve user experience as it might involve additional processing which may impact user response time in other way. Choice D could also be considered valid but it is not the main reason for the purpose of enabling audit trails.In a risk based audit strategy, risk assessment is done by IS auditor to ensureRisk mitigation controls are in placeThreats and vulnerabilities are identifiedRisks related to audit are taken into consideration hatchway outline is done as per the needAns. BExplanationChoice B is most appropriate in this scenario. Identification of threats and vulnerabilities is crucial in determining the scope of audit. Effect of an audit would be to develop controls to mit igate risks. Audit risks are not relevant to risk analysis of environment. Gap analysis compares the developed state to expected or desired state. A gap could be result of a risk not being correctly addressed or missed out.In order to achieve best value to organization in terms of audit resources we should Do audit scheduling and measure the time spent on auditsTraining of audit staff on latest audit technologiesChalk out detailed plan based on risk assessmentProgress monitoring of audits and have cost control measures in placeAns. CExplanationChoice C is most appropriate in this scenario. This will deliver value to organization in terms of dedicating resources on higher risk areas. Choice A, B and D will improve the staff productivity lonesome(prenominal).An IS audit charter includesPlan for IS audit engagementsScope and objective of audit engagementTraining plan for audit staffIS audit function roleAns. DExplanationChoice D is relevant in this scenario. Choice A is responsibili ty of audit management. Scope and objective is agreed on engagement letter and training of staff is again responsibility of audit management based on audit plan.In the evaluation of risk assessment of Information system. The IS auditor will first reviewControls in placeEffectiveness of implemented controlsMonitoring mechanism for risks related to assetsThreats/ vulnerabilities impacting assetsAns. DExplanationRisks associated with utilize assets need to be evaluated first so choice D is most appropriate in this scenario. Controls effectiveness is part of risk mitigation stage and risk monitoring is part of risk monitoring function after risk assessment phase.During an audit plan, the most critical pervert isHigh risk areas realisationSkill set identification of audit teamIdentification of test steps in auditIdentification of time allotted to auditAns. AExplanationThe choice A is appropriate in this scenario. The identification of high risk areas is most critical step as that will determine the areas to be focused during the audit. Skill set is determined before audit to begin. Test steps and time for audit is determined on the basis of areas to be audited.How ofttimes selective information to be still during audit process will be determined on the basis of hush of obtaining the information recordsFamiliarity with the environment to be auditedEase of obtaining the evidenceScope and purpose of auditAns. DExplanationScope and purpose will determine the amount of sample selective information to be collected during the audit. All other choices are irrelevant in this scenario as audit process is not hampered by ease of obtaining records or evidences or familiarity with the environment.During the audit plan, assessment of risk should provideAn office that audit will cover material itemsMaterial items would be covered definitely during the audit conk outReasonable assurance that All items will be covered by audit workAssurance to suffice that all items will be covered during the audit workAns. AExplanationChoice A. ISACA audit guideline G15 clearly states that An assessment of risk should be made to provide reasonable assurance that material items will be adequately covered during the audit work. Definite assurance clause in choice B is impractical, option C is also not correct as it states all items.Statistical sampling should be used by IS auditor and not judgmental sampling in the scenarioObjective quantification of error fortuneAvoidance of sampling risk by auditorGeneral use audit software program is availableUnable to determine the tolerable error rateAns. AExplanationWith an expected error rate and confidence level, objective method of sampling is statistical in nature as it helps auditor to determine size of sample and quantify error probability or likelihood. Choice B is not correct because sampling risk is risk of sample. Choice C is also incorrect as statistical sampling doesnt need general software. Choice D is also incorrec t because tolerable error rate is predetermined in statistical and judgmental sampling.The primary goal of an auditor during the IS audit planning stage isAddress audit objectivesSufficient evidence collection put forward appropriate testsUse less audit resourcesAns. AExplanationAs per ISACA guidelines auditor plan must address audit objectives. Choice B is not correct because evidence is not collected at planning stage. Choice C and D are also incorrect because they are not initial goals of audit plan.During an audit procedure selection, auditor will have to use professional judgment to ascertainSufficient evidence collectionIdentification of substantive deficiencies and there correction in reasonable time periodMaterial weakness identifiedMaintain minimal level of audit costsAns. AExplanationProfessional judgment during the course of an audit process involves subjective and qualitative evaluation of conditions. It is based more on past experience of auditor and auditor past expe rience plays a key role in this. Identification of material weaknesses is result of experience and planning thoroughness and also it does not charter with financial aspects of audit as stated in choice D.While evaluating logical access controls an auditor firstDocumentation of controls applied to all possible access paths to systemTesting of controls to access paths to determine they are functionalEvaluation of security environment w.r.t. policies and procedures laid downObtaining an understanding of security risks to information processing facilitiesAns. DExplanationChoice D is most appropriate in this scenario. The first step is to gather security risks to information processing facilities, by studying documentation, inquiries and doing risk assessment. Documentation and evaluation is next step. Third step is to test access paths to ensure controls functionality. The last is auditor evaluation of security environment.The objective of rhetorical audit is toParticipation in invest igations related to corporate fraudEvidence collection on systematic basis after system geometrical irregularityAssessment of correctness of organizations financial statementsDetermine if there was any criminal activityAns. BExplanationChoice B is correct as evidence collection is used for juridical process. They are not however for corporate frauds. Financial statements correctness determination is not purpose of forensic audit. And criminal activity could be part of legal process but it is not the objective of forensic audit.An auditor is reviewing a backup log report of remote innkeeper backup. One of the entries in the backup log indicates failure to login to remote server for backup and there is no entry in log which confirms that backup was restarted. What IS auditor should do?Issue audit findingExplanation required from IS managementIssue a non complianceIncrease sample of logs to be reviewedAns. DExplanationChoice D is appropriate in this case. Before issue audit finding or seeking explanation, or issue of non compliance auditor take to gather additional evidence to properly evaluate the situation.For the purpose of auditing critical servers audit trail, auditor wants to use _______ tool to determine the potential irregularity in the user or system.CASE toolsEmbedded data collection toolHeuristics scanning tool bring down/variance detection toolsAns. DExplanationTrend/variance detection tools are used for determining the potential irregularity in the user or system. CASE tools are used in software development and embedded data collection tool is used for sample collection and Heuristics scanning tool used to detect virus infections.What could be the possible cause of great concern for an auditor while evaluating a corporate network for possible penetration from employees?Number of external modems connected to networkUsers have right to install software on there desktopsLimited network monitoring or no monitoring at allUser ids with kindred passwo rdsAns. DExplanationChoice D is most appropriate in this scenario. It is the greatest threat. Choice A threat is there but depends on use of valid user id. In choice b likelihood is not high due to technical knowledge needed for penetration. meshing monitoring is a means for detection.What is the major benefit of using computer forensic softwares in investigations?Preservation of electronic evidenceSaving time and costsMore expeditious and effectiveEfficient search for violation of Intellectual property rightsAns. AExplanationThe main purpose of forensic software is to preserve the chain of electronic evidence for investigation purpose. Others choice B and C are concerns to identify good / poor forensic software. Choice D is example of using forensic software.Data is imported from client database by auditor, now the next step is to confirm imported data is complete, what step need to be followed to verify the same. tally control arrive of imported data with cowcatcher dataSort d ata to confirm data is in same order as the accepted dataReview first 100 records of imported data with first 100 records of original dataCategory wise filtering of data and matching them to original dataAns. AExplanationThe logical step in this scenario would be option A. this will confirm the completeness of process. Sorting may not be applicable in this scenario because original data may not be sorted order. Reviewing partial data does not suffice the purpose either. Filtering data would also need control totals to be established to ensure completeness of data.An audit is to be conducted to identify payroll overpayments in last year. Which audit technique would be best appropriate in this scenario?Data testingUse of general audit softwareIntegrated test facilityEmbedded audit moduleAns. BExplanationGeneral auditing softwares include mathematical calculations, stratification, statistical analysis, sequence and duplicate checks and re-computations. So auditor can use appropriate t ests to re-compute payroll data. Test data would not detect the anomalies and overpayments. Integrated test facility and embedded edit modules cannot detect previous errors.During an audit process, auditor finds out that security procedures are not authenticated what he should do?Auditor create procedure documentStop auditDo compliance testingEvaluate and identify exiting practices being followedAns. DExplanationThe purpose of audit is to identify risks, so the most appropriate approach would be identify and evaluate current practices being followed. Auditors dont create documentation, compliance testing cannot be done as no document is there and stopping audit will jeopardize the objective of audit i.e. risks identification.Threats and their potential impacts are identified during the course of an risk analysis stage what should be next most appropriate step?Identification and assessment of risk assessment approach of managementIdentification of all information assets and systemsD isclosure of threats and impacts to managementIdentification and evaluation of existing controlsAns. DExplanationThe next step would be choice D. once the threats and impacts are identified. Next step is to share them with management.Out of the following which one is the most significant concern for an auditor?Non reporting of network bombardmentNotification failure to police of an attempted intrusionPeriodic review of access rights not presentNo notification of intrusion to publicAns. AExplanationFailure to report a network attack is major cause of concern. Reporting to public is organization choice and notification to police is also matter of choice. Periodic examination of access rights could be causing of concern but not as big as option A.Which is the most secure evidence for an auditor out of the followingLetter from 3rd party on complianceLine management assurance that application is performing as per designInformation obtained from wwwReports supplied by organization manag ement to auditorAns. AExplanationThe most reliable evidence is the one given by external party. Choice B, C and D are not considered reliable.While evaluating a process on the basis of preventive, detective and corrective controls, an IS auditor should know?The point at which controls used as data flow through systemPreventive and detectives controls are only relevant onesCorrective controls are only relevantClassification is required to determine which controls are absentAns. AExplanationChoice A is most appropriate. Choice B and C are incorrect as all controls are important. Choice D is also not correct because functioning of controls is important and not its classification.The best evidence of duties separationism is identified by using ____ audit technique?Discussions with managementOrganization chart reviewInterviews and observationsUser access rights testingAns. CExplanation base on choice C an auditor can evaluate the duties segregation. Management may not be aware of detail ed functioning, organization chart only depicts hierarchy of reporting, and testing will only tell user rights but will not give any details on function being performed by users.While reviewing a customer master file, auditor discovers that many customer names are appearing in duplicate causing sportswoman in customer first names. How auditor will determine the amount of extra in this scenario?Testing data to validate inputTesting data to check sorting capabilitiesUse general audit software to detect address field duplicationsUse general audit software to detect account field duplicationsAns. CExplanationAs names are not same, so we need to use some other field to determine duplication such as address field. Test data will not help in this case and searching on account number may not yield desired result because customers could have different account numbers for each entry.While testing for program changes what is the best population to take aim sample from?Library listings testi ngListing of source programsChange request programsListing of production libraryAns. DExplanationThe best source to plenty sample or test system is automated system. Choice B would be time consuming. Program change request are initial documents to give lessons changes test libraries dont present approved and authorized executables.An integrated test facility is an efficient tool for auditAudit of application control in a cost effective mannerIntegrating audit tests for financial and IS auditorsComparison of processing output with independently calculated dataTool to analyze large range of informationAns. CExplanationIt is a useful audit tool because it uses similar program to compare processing with independently calculated data. This involves reach up dummy entities and processing test/production data.IS auditors use data flow diagrams toHierarchical ordering of dataHighlighting high level data definitionsSummarize data paths and retentivity in graphical mannerStep by step deta ils of data generation portraitAns. CExplanationData flow diagrams are used to chart flow of data and storage. They dont order data in hierarchical manner. Data flow not inescapably match hierarchy or order of data generation.Review of organization chart is done by auditor toUnderstand workflowsIdentify all communication channelsResponsibility and authority of individualsNetwork diagram connected to different employeesAns. CExplanationOrganization chart always depicts the responsibility and authority of individuals in an organization. This is required to understand the segregation of functions.While performing an audit of network operating system, an auditor should review the following user feature?Network document availability onlineSupport for terminal access to remote systemsFile transfer handling between users and hostsAudit, control and performance managementAns. AExplanationNetwork operating system user features comprise online availability of network documentation. Choice B, C and D are some examples of network OS functions.In order to ascertain that access to program documentation is only restricted to authorize users, an auditor should checkEvaluation of retention plan for off site storageProcedures being followed by programmersComparison of utilization records to operational scheduleReview data access recordsAns. BExplanationInterview of programmers to understand procedures being followed is the best way to ascertain the access to program documentation is only with authorized personnel. Off site storage, utilization records and review of data access records will not address security of program documentation.Auditor is evaluating an application which does computation of payments. During the audit it is reveled that 50% of calculation is not matching with the set total. What should be the next step auditor need to follow as part of audit practice?Do further test on calculations having errorIdentification of variables that generated in absolute test r esultsTestify some more test cases to reconfirm the anomalyDocumentation of results, findings, conclusions and recommendationsAns. CExplanationAuditor needs to examine some more test cases where incorrect calculations happened and then confirm with the final outcome. Once calculations are complete further tests can be performed and then report to be made only after confirmation and not before that.In order to prove the correctness of system tax calculation the best practice to be followed isIn depth review and analysis of source codeUsing general auditing software to recreate program logic for monthly totals calculationSimulate transactions for results comparisonIn depth analysis and flow chart preparation of the source codeAns. CExplanationThe best way to prove trueness of tax calculation is simulation of transactions. Detailed review, flow chart and analysis of source code will not be effective and monthly total will not confirm the correctness of tax calculations at individual le vel.In Applications control review , auditor must analyze Application efficiency in meeting business processesExposures impactBusiness processes performed by applicationOptimization of applicationAns. BExplanationApplication control review requires analysis of application automated controls and analysis of exposures due to controls weaknesses. The other options could be objective of audit but not specifically meant to analyze application controls.What is the most accurate evidence to prove that purchase orders are legitimate while auditing an inventory application?Application parameters can be modified by unauthorized personnelPurchase order tracingComparison of receiving reports to purchase order detailsApplication documentation reviewAns. AExplanationAccess control testing is the best way to determine purchase orders legitimacy and is the best evidence.

Impact On The Natural Environment Construction Essay

Impact On The Natural Environment Construction EssayThe construct sphere of influence has a signifi ceaset feign on the earthy environs. It consumes almost 33 of the worlds natural resources, including 40 of its zip fastener and up to 12% of its water. These estimates do not consider embodied aptitude (i.e. the cleverness put ond to obtain, manufacture, subroutine and dispose of grammatical construction materials), which butt end represent a significant proportion of a twists mannerstime nothing breathing in. The building sector is in rise to power responsible for 40% of global green-house gas (GHG) emissions and 40% of the waste which ends up in the landfills (World Green Building Council, 2006). The consumption of natural resources, particularly none-renew fit energy sources, is an important factor in the economy of many nations. Authorative reports show much(prenominal) trends in many parts of the world. In the United Kingdom, for instance, the building sector c onsumes almost 50% of all the countrys energy. patch in the United States, nigh 40% of the total national energy production and almost 70% of electricity production is apply in the building sector, as vigorous as 28% in transportation a factor which is partly influenced by urban frame. The building sector in mainland China currently floors for 19% of the countrys total energy consumption. This relatively small percentage is due to energy intensive industrial production. The same scenario occurs in the rich oil-producing argonas of the disjunction Corporation Council Countries (GCCC). For example, the building sector in Kuwait account for nearly 45% of the yearly electric energy consumption, whilst in Saudi Arabia this sector consumes about 70% of the total electricity consumption. In Bahrain, the smallest country within the GCCC, buildings account for 83% of the national consumption of electricity (EIA, 2010).Apart from its energy consumption, the building sector is also on e of the largest contributors to changes in the purlieu and atmosphere number 1ly, building verbalism, raw material processing and product manufacturing boilersuit ar the largest sources of GHGs. They account for approximately 40% of the world GHGs emissions. The building sector creates the most waste, habitat destruction and is responsible for the most pollution. Second, GHGs, particularly carbonic acid gas, are the main by-product of fossil fuel energy consumption, and as buildings are, in total, among the largest consumers of energy, they are also the major contributor to the increase in CO2 emissions and hence global warming. While most available data link up to these contributions are for the developed world, reports show that, on the whole, these contributions are worse in developing countries such as the GCCC. These countries have become major GHGs emitters. gibe to the International Panel of Climate Chang (2007), the GCCC are amongst the top countries in flat coa t of CO2 emissions per capita. Recent statistics show an increase of CO2 emissions due to excessive energy consumption in different GCCC sectors, particularly the building sector. The increase in CO2 emissions had been within the range of 30-35% between 1997 and 2006. The GCCC are found to contribute dickens and half per cent of the global GHG emissions (United Nations Statistic Division, 2007).One of the main principles of the GCCC is to enhance the frugal and environmental actions related to the adoption of policies and unifying environmental laws as well as the conservation of natural resources (GCC, 2008). Within this context a two-fold policy aims at promoting energy regulations and sustainable developments has been adopted. A major fictitious character has been given to the building sector, with a special focus on the important role that efficiency regulations can play in reducing energy consumption and protecting the environment.On the ground, manywhat actions have been taken by the GCCC in order to achieve sustainability in buildings, such as the implementation of green building regulations. Most of these regulations are establish on the USAs Green Building Councils (US GBC) Leadership in Energy and Environmental Design (LEED) rating constitution, with modifications made to account for the local environmental conditions. In terms of green construction, many attempts have been made in different parts of the GCCC. Examples can be seen in the Bahrain World Trade Centre in Manama, the large Masdar City in Abu Dhabi, the campus of King Abdullah University of Science and Technology in Saudi Arabia and the Energy City in Qatar. These projects incorporate several efficiency techniques and green materials. A consideration of these huge, costly projects shows that three parties can benefit from such developments governments and owners can save energy and protect the environment, thereby gaining a favourable image contractors and suppliers can sell green p roducts and developers can use the affirmative image as a positive marketing tool. However, in his article The Business of Green Elsheshtawy (2010) claims that some green and LEED certified buildings in the GCCC end up consuming much more(prenominal) energy than the evaluators predicted due to poor energy practices. Coupled with this is the economics of energy efficiency and green buildings.Cost of building greenA great number of available projects, such as those mentioned above, shows that if building green is a indicate at the outset of the design process and material selection then the cost of the green building is competitive. In a commercial setting, such projects can result in reduced energy consumption, saved environment, improved occupant health and comfort and reduced capital costs. Many rigorous assessments show that the overall cost of these projects is no more than that of any equivalent conventional project. Increases in graduation exercise cost are reported within t he range from quint-ten per cent. During the construction anatomy the use of the green strategies, such as downsizing of costly mechanised, electrical and structural formations can increase the saving in initial costs, while during the counterbalance two decades the increases due to the use of green technologies leave behind result in a savings of at least ten times the initial enthronement in operation costs for utilities such as electricity. In rental properties, owners are concerned only with the initial cost, especially in the cases where tenants are compensable the bills. Governments and some owners, however, can realise the energy savings and so are willing to pay more for minimising the operation cost and reducing the environmental fix. The tradeoff between economic costs and environmental benefits can stimulate people on the basis that adoption of green technologies will have environmental and fond benefits outside the margin of cost consideration. Although the con cept of eco-efficiency, in many cases, does not take into account the social benefits, such an draw close can balance environmental design with cost-effectiveness.To achieve eco-efficiency in the building sector, it is necessary to apply an merged approach with the assistance of a team of professionals across different areas. This is realised in what is called the whole building approach. This approach represents a key factor in the design and construction of green buildings, especially with the pull ahead of technology and increased complexness of constructional systems. The incorporation of the whole building approach at the projects conceptual design phase enables the evaluation of a buildings design, materials and systems from the perspectives of all the project team members as well as from the perspectives of owners and occupants. A principal advantage of this approach is the coordination and mutual dialogue between project team members, which represent a cornerstone for any triple-crown projects. By applying the whole building approach initial and other cost savings can be realised, energy efficiency evaluated and environmental regard assessed.The role of lining systems in making buildings greenGreen buildings are generally knowing and built in an ecological and resources-efficient manner. They often respond to their local environment and, therefore, different building designs are found in different regions. In any region, however, the ultimate target of green buildings is to ply a comfortable environment in an economic way. The buildings skin, particularly building window dressing, represents the connection between the internal environment and the outside conditions, and hence a key function of the building facade is to reduce the need to modify the indoor environment as little as possible in response to the environmental load from the outdoor climate. Sometimes, a building facade fails to meet its objective due to one or more reasons, such as the insufficient design of paries systems or the contrasted selection of cladding materials that probably make it impossible for any specific level of comfortable environment to be achieved. Then, it is necessary to rely upon electrical and mechanical systems to achieve comfort. This reliance leads to higher cost which is translated into bigger capacity requirements for lighting and mechanical equipment and higher capital costs for such equipment as well as larger amounts of energy consumption by the lighting system and heating, ventilation and air-conditioning (HVAC) system. In contrast, efficient environmental design and appropriate selection of green cladding materials can result in a comfortable inside environment, reduced project initial and running costs and a building that is energy and resource-efficient with press down operating costs than conventional buildings. Practitioners have demonstrated that the implementation of green strategies contributes to a buildings comfor t, economic and energy cognitive operation. The use of green cladding systems, in particular, is able to make a significant stupor on the thermal and operational performance of green buildings. Reports show that when green cladding systems are taken into account at the conceptual design phase, significant improvements in the energy performance can be achieved (Radhi and Sharples, 2008).Aside from their influence on building operational energy, the external wall systems and cladding materials are major contributors to changes in the natural environment. The production of construction materials such as precast and aluminium increases atmospheric concentrations of GHGs. The environmental move starts with the chemical reactions during the production phase, where such materials represent one of the largest source of CO2 emissions and other GHGs. Then, the transportation of the materials to construction sites consumes considerable amounts of primary energy and generates high levels of GHG emissions. At the installation phase these materials generate different types of waste, whilst at the operation phase some of them influence the interior and exterior spaces by producing unhealthy components into the air. Some construction materials have relatively short useful lives and, consequently, the disposal and manufacture of repla cement materials occurs, thereby generating more GHGs and waste. Research experts have shown that a careful selection of pitiful environmental impact components and materials reduces the CO2 emissions by up to 30%. Some cladding materials are reported to have the capacity to reduce ozone emissions and other sources of pollutants such as CO2 (Radhi, 2010).How can the eco-efficiency of cladding systems be staird?The World Business Council for Sustainable Development (WBCSD, 2000) terms eco-efficiency as the synthesis of economic and environmental efficiency in parallel. Within this context, eco-efficiency in the building sector can be determi ned by three broad objectivesReduce natural resources consumption by minimising the use of embodied and operational energy, raw materials, water and land as well as enhancing recyclability and material durabilityReduce environmental impact by minimising GHGs emissions, waste disposal, water discharges and the dispersion of toxic substances, as well as encouraging the use of renewable resources.Increase the value of materials and systems by providing more benefits through and through material working(a)ity, flexibility and modularity.In the light of these objectives the important question is how the eco-efficiency of cladding systems can be measured. Significant scientific work has been addressing this issue by introducing suitable assessment methodologies and rating systems. This is best(p) seen in the environmental life cycle assessment (LCA) and life-cycle cost (LCC) approaches developed by the international standards for LCA principles and framework ISO 14040 (ISO14040, 2006). judicial decision is performed in four phases, including goal and scope definition, inventory analysis, impact assessment and interpretation. Two main approaches are available to classify and characterise environmental impacts. The first is the problem-oriented approach (mid-point). The second is the damage-oriented approach (end-point). A great number of methods have been developed below these two approaches such as the critical volumes (weighted load) and ecological scarceness (eco-points) systems in Switzerland, environmental priorities system in Sweden, eco-indicator 99 in Netherlands and the environmental problems system in the United States. The use of such methods makes it possible to select building systems and materials that achieve the most appropriate balance between environmental and economic performance based on certain values of the building team.Case carry assessing eco-efficiency of cladding systems in BahrainThe current assessment, based on the LCA of residenti al buildings (Radhi and Sharples, 2012), is performed to characterise the eco-efficiency of cladding systems in Bahrain. Bahrain is chosen as many of its building construction approaches and techniques are typical of those found in the GCCC. The production, construction, use and disposal of a 75 m2 front facade of a typical Bahraini house (Fig. 24.1), formed the basis of this assessment. Technically, the building facade consisted of two main components that included the wall system and cladding layers. The wall system is generally classified as cavity wall, barricade wall or mass wall (National Institute of Building Sciences, 2012). The cavity wall (sometimes called the screen wall system) is the preferred method of construction in many climatic regions due primarily to its ability to achieve pressure-equalisation. The barrier wall is an exterior wall system of assembly. The principal dissimilitude of this system is its ability to integrate the surfaces of outermost exterior wall and construction joints, which can offer resistance to bulk moisture ingress. The mass wall relies principally upon a combination of wall thickness and storage capacity. Some fundamental differences exist among these systems such as the thermal performance, fire safety, moisture protection, acoustics, maintainability and material durability, and so consequently their impact on the environment.In terms of cladding, it is the exterior finish layer that is installed to cover wall systems and/or support structures. This finish layer serves several functions, including improving appearance, optimising thermal and environmental performance and keeping undesirable outdoor elements away. Today cladding systems are available in many forms and materials, which are often chosen based on economic and aesthetic factors. Structurally, the use of any alternatives of cladding determines the type of wall system and vice versa. The mass wall system, for example, can form structural elements or finish ed cladding systems. This system is commonly associated with plaster and masonry cladding systems. On the other hand, the barrier wall is used with precast concrete spandrel panels and some types of metal cladding systems such as composite and solid metal plate as well as with exterior insulation and finish systems (EIFS).With the advance in building technology and construction materials, many alternatives of cladding systems are now available in the market. Examples are studied in the current work, namely, stucco, masonry veneer, marble, ceramic tile and the EIFS. Stucco is a hard, dense, thick and non-insulating material, such as cement plaster, that can be used to cover exterior wall surfaces. Both Portland cement and masonry cement are used with sand for the base and finish coats of stucco exterior walls. Unlike the ordinary stucco system, the EIFS (also known as synthetic stucco) is a lightweight synthetic wall cladding that includes foam plastic insulation and thin synthetic c oatings. The masonry veneer is made from a mixture of Portland cement and aggregates under controlled conditions. It provides cladding and resists transferring wind and heat loads to the building support structure. The marble cladding system is a natural stone, while the ceramic tile cladding system consists of a mixture of clay and other ceramic materials. To improve environmental and thermal performance, recycled windshield glass is often added to the ceramic mix (Brookes and Meijs, 2008). These pentad cladding systems are assessed under real construction and thermal scenarios with the same wall system (mass wall), as illustrated in Fig. 24.2. To provide each scenario with the basic systems quantities per functional unit, the existing facade parameters and wall materials of the typical house are considered as a reference scenario, in addition to the operational aspects that are influenced by the building facade.Data inventory of cladding systemsThe LCA method and LCC technique ar e integrated to deliver a complete and detailed assessment of the overall potential impact of the typical house. An important point to note is that system and material selection based on a single impact could obscure other factors that mogul cause equal or greater damage. Therefore, the adopted LCA methodology takes a multidimensional life-cycle approach, in which multiple environmental impacts are considered over the entire life of the assessed cladding systems. To balance the assessment, the LCC is performed over a 60 year life span, and is based on published data and methods outlined in (Radhi 2010). Categories of expenditure typically include costs for purchase, installation, maintenance, repair and replacement. Measuring the economic performance is relatively straightforward by using real cost data collected through a field study. The data in question are the real cost data that occur and the subsequent cost, which will occur in the future. normalisation is carried out in this work in order to present a more useful scale of measurement and to make relations of various systems simpler. Normalisation is an optional step in impact assessment and can be described as a form of benchmarking, where the flows of each environmental impact are first summed and then divided by fixed Bahraini scale impact values. This can yield measures that are placed in the context of Bahraini action contributing to that impact. The placing of each measure in the context of its associated Bahraini impact measure makes it possible to reduce different values to the same scale and allows the comparison across impacts. The resulting performance measures are, thus, expressed in non-commensurate units. For credibility, the commercially available BEES model (National Institute of Standards and Technology, 2007) for building construction materials coupled with the international inventory data (Hammond Jones, 2011) were used to compare and check. The BEES model is generally used to meas ure the environmental and energy performance of building products and facade materials using the life cycle assessment approach outlined in ISO standard 14040.Environmental impact assessmentGiven the desire to link environmental and economic performance through the concept of eco-efficiency, the nonsuch way is to base the eco-efficiency indicators on international agreement as far as possible. According to the framework of the United Nations (2006), the assessment of eco-efficiency includes various generic environmental issues such as energy use, global warming contribution, water use, ozone depletion substance and waste. From these indicators, energy consumption and CO2 emissions, water use and ecological toxicity are of the greatest relevance for this study. Fig. 24.3 compares these indicators with respect to the five studied cladding systems. Some of these systems, such as the marble cladding, have significant impacts on water use but moderate impacts on global warming and embod ied energy. Other systems, such as stucco, have a significant impact on two the energy consumption and global warming but a modest impact on water use. The others, such as the EIFS, have a minor impact on different generic environmental issues. From the illustration, the EIFS system seems to be the best performer, followed by the ceramic tiles, marble and finally the brick. Stucco is found to be the least effective system in terms of energy consumption and ecological toxicity as well as in relation to CO2 emissions. This can be related to the large amounts of CO2 emissions during cement production, which is the main component of the plaster cladding system.Environmental versus economicWhen the overall environmental impact of the examined systems is considered, a different scenario occurs. The overall environmental performance is illustrated in Fig. 24.4. Two main observations can be highlighted firstly, the overall environmental performance ranking of the five systems is different from single measures such energy use and global warming. The EIFS cladding system is the best environmental performer, whilst the ceramic tile system is the worst performer. The difference is more than 24 points. As systems with lower scores are greener, the EIFS cladding system is greener because it contributes, on average, 0.1% of annual per capita Bahrain environmental impacts, whilst the marble contributes a larger share, 0.35%. Secondly, the environmental performance ranking is different from that of the economic performance. The illustration shows that the economic impacts of cladding systems are various and different from the environmental impacts. For example, the stucco cladding is illustrated as the best economic performer, but it is not in terms of the environmental performance. The difference in score is significant, being almost 11 points. This can be also seen in the case of the ceramic tile cladding. In contrast, the marble cladding achieves a high overall environmen tal performance and a low economic performance with a difference that reaches almost 21%. The EIFS cladding seems to have a balanced environmental and economic status. The same ranking occurs when both environmental and economic performance are estimated.By using the multi-attribute decision analysis technique, environmental indicators and the economic performance are combined into an overall performance measure (National Institute of Standards and Technology, 2007). It is important to mention that the overall performance scores in this work are not indications of absolute performance. Rather, they are reflecting proportional differences in performance and representing relative performance among system alternatives. By following this procedure, these scores can be changed when the number of system alternatives are increased or reduced. The potential overall performance of the studied systems shows different scenarios when compared with the environmental and economic performances. Th e stucco cladding seems to be the most eco-efficient systems in kindle of its poor environmental performance, followed by the EFIS system with a score of 29%, with the masonry veneer coming next. In contrast, the ceramic tile cladding is found to be the worst with almost 50%, in spite of its moderate economic performance.Overall, different cladding systems have different environmental and economic performances. Some cladding materials improve the environmental performance, but provide a moderate influence in terms of economic performance, and vice versa. Others positively improve the environmental performance and can optimise the economic performance. Therefore, a careful eco-efficiency assessment should be undertaken in selecting wall cladding systems. Such an assessment can benefit the appraisal of green cladding systems and hence into the design decisions made in developing various scale of green buildings.ConclusionTodays modern buildings systems, particularly cladding system, are often selected and assessed based on esthetics and cost rather than their environmental performance or their overall potential impact. The concept of eco-efficiency introduced in this book balances the environmental performance with economic aspects. This chapter presented a positive eco-efficiency assessment of cladding systems and explored its role progressing a green future in the building sector. The interrelation between environmental indicators and economic performance was examined by comparison various cladding systems, considering both overall environmental impact indicators and life cycle cost. The differences in environmental indicators of various cladding systems, namely, stucco, masonry veneer, marble, ceramic tile and the EIFS systems, are generally significant. The ranking of these systems in terms of environmental and economic performance are different. Some of the cladding systems, such as the marble cladding, reduce energy consumption and CO2 emissions, but pr ovide a minor reduction in terms of the life cycle cost, and vice versa. Others, such as the EFIS system, impact positively upon the environmental indicators and can optimise the overall potential impact. This system has the ability to reduce energy consumption and CO2 emissions however, other aspects, such as maintenance and life expectancy, should be considered at the time of system selection.The scope of the current study focused on the eco-efficiency of representative residential cladding system in a developing country. Consequently, the outcome of this assessment may not be applied to buildings in countries with different economic and environmental situation. In spite of this shortcoming, this assessment approach may provide useful quantitative and qualitative information for cladding design decisions. Therefore, it is important to highlight some general notes forward-looking green building technologies, such as the exterior insulation and finish systems (EIFS), are effective c ladding systems in promoting a green future in the residential building sector.To improve the overall potential impact, wall cladding systems in desert climate regions, such as Bahrain, can be designed as exterior insulation and finish systems.Every building is unique in both design and operation. Academic experts and practitioners benefiting from this work should consider the impact of related variables, and therefore a careful assessment must be performed during the selection process in order to achieve eco-efficiency in the building sector.In addition to its ability to assess building cladding systems, the eco-efficiency concept can be used with various other systems, materials and innovative applications. It can yield a small assessment in the case of multifunctional problems in relatively short times and at relatively low cost. In the near future the concept of eco-efficiency will become more important in the context of the green built environment in order to show which design process, building systems and renewable technologies are more favourable than other alternatives.

Cheetahs in Zoos :: essays research papers fc

Cheetahs in Zoos Cheetahs in immurement should be left there, not released into the wild, and on the same line of work cheetahs in the wild should be left there, not brought into captivity. A cheetah in a zoo that is released into the wild whitethorn not know what to do, having been cargond for by people in an enclosed environment for a number of years and then suddenly thrust out into the wild and on its own may have adverse effects on the cats psyche, making it manic or exhibit unpredictable behaviors and endangering the wildlife already there.Cheetahs living in captivity generally live a great deal longer than those in the wild, the life span of wild cheetahs is about 8 to 10 years, as distant to 12 to 17 years for those in captivity according to the National Zoological Park, a sure fire sign of a healthy life. Cheetahs are also relatively easy to tame, in comparison to other large cats, and very hard to assimilate into the wild once theyve become accustom to benignant contac t (NZP), which makes one wonder if they even want to be released in the first place.While cheetahs do live longer in captivity, they do not breed as often Steven Hunt states that up until recently cheetahs living in captivity would only have one and occasionally two litters in their lifetime, whereas cheetahs in the wild may have up to five. In recent years, however, breeding programs in zoos have become more successful, allowing for a more racy captive population and much hope for the future of the species. By maintaining the integrity of this population, a strong gene pool can be assured composition keeping hold of the prospect of future release of younger cheetahs. Since these cubs may not have been tamed and may still adapt to life in the wild with relative ease.Another problem with releasing captive cheetahs into the wild is space. According to The Cheetah Spot, the cheetahs native habitats have been cut cut out to less than a quarter of what they were ten years ago. This mak es release of captive cheetahs not only difficult, but possibly hazardous to cheetahs already in the wild. Do to the fact that they are mostly solitary animals, females live alone unless raising cubs and males roam with, at most, four other males (NZP). Introducing more cheetahs into an already small heavens may very well upset the social system of cheetahs by putting them in too much contact with each other.

Decadence and Aestheticism :: History Historical Papers

Decadence and AestheticismMany may wonder if the era of the 1890s was the beginning, end, or change of a virgin age. The era can often be described as modern, advanced, and different. Many people were experimenting, inventing, and trying new things. Decadence and Aestheticism arose.Decadence emerged as a bad side of Romanticism in that it involved forbidden experiences. Decadence was referred to as moral, social, and artistic. As Beckson says, The dark side of Romanticism derived from Poe and other writers who defined it as strangers join with beauty(Page 40). The distinguishing feature of a Decadent is the retreat of reality. For example in The Importance of Being Earnest by Oscar Wilde, Algernon and Jack have a spend a penny character that they often used as an escape from reality. Decadence represented Symbolism and Impressionism. Also known as fin de siecle, Decadence is described by Arthur Symons, a participant observer who said, it has all the qualities that mark the end of great periods, the qualities that we find in the Greek, the Latin, the Decadence, an intense self consciousness, a restless curiosity in research , and a spiritual and moral perversity.(Altick Page 296). In Aestheticism, life is viewed as an art. Aesthetes found beauty in art and in whatever was fetching in the world. Altick said, The connecting link was Rosetti, whose poetry and painting inspired the Aesthetes( rogue 291). Arts purpose for the Aesthete was for pleasure. The Aesthetics interpreted his artistic aim as the prosecution of beauty separated form social meaning. Oscar Wildes theory towards Aestheticism was that the only reality worth seeking was not material goods but the individual experience. And so Aestheticism involved a complete revulsion against received standards of values. Aesthetics found that through their great interest in beauty, pleasure that is derived form objects of art is much beautiful than other pleasures.The truth about an Aesthete is that the mind is usually more active in a creative sense in the cargo deck of nature than in the enjoyment of a finished work of art. An Aesthete has a great appreciation for nature. One may look at an object, place, or person and perceive it a different way than another person may perceive it. He does not actually see them the way they get on but his imagination gives his perception a memory picture of them. For an Aesthete to obtain pleasure, it is the perspectives of perception that is necessary to an understanding of both appreciation and creation(Langfield page 24).
