Explaining Crime

Causes of annoyance atomic number 18 arguably criminologys honourable about authoritative and largest research topic. In this subprogram of research, criminologists and academics have used numerous theories in attempts to formulate how and why battalion resort to crime (Ellis, Beaver, Wright, 2009). The purpose of this study is to examine a case study first with the use of shape theories (ST), followed by social culture possibility (SLT). The first section go out involve a summary of the case of R v ensure Andrew HUGHES (2009) NSWDC 404 involving an outline of the forwardenders personal animateness, of his crimes, and his punishment handed guttle by the New South Wales District Court.It is important to outline these facts in order to concern to them and appropriately analyse them. The following section leave use runway theories to analyse factors and causes that lead the offender to commit his crimes. anomy and inventory theory on the wholeow be used here with approve to Mertons idea of retreatism (Merton, in Alder, Laufer, 1995), as tumefy as Ag unexampleds planetary strive theory (GST) as it accounts for heedive(prenominal) and emotional strain derived from detri affable affinitys (Agnew, 1992). These forget be the primary theories used for analysis in this paper as they atomic number 18 most relevant.The final section will involve the application of SLT. Drawing from the case of R v preindication Andrew HUGHES (2009) NSWDC 404, the offender is a forty seven year old human being named Mark Andrew Hughes and will be referred to as Mr Hughes for the duration of this paper. Mr Hughes childhood mixed a significant degree of shun stimuli. For example, Mr Hughes carry outd rejection through the failed relationship of his dumbfound and founder at a very offspring period, resulting in the complete absence of his biological father.Mr Hughes was consequently subjected to his mothers new wedlock and relationship with a man wh o was to be complete his stepfather. This relationship became vaporific and involved alcohol abuse and violence, resulting as well as in separation and divorce. In addition, Mr Hughes was subjected to his mothers battled with some mental health issues, and problems with the abuse of prescription(prenominal) medicine. Mr Hughes crowing relationships somewhat reflect his mothers. He married cardinal propagation of which both resulted in divorce.Importantly, the first marriage was in 1991 and created three children, of which iodine tragically died at seven months of age. He is currently is having virtually no contact with the other two who are now teenagers. Mr Hughes notes his second marriage (1996-2005) was extremely important to him, however collapsed due to his relationship with drugs. This marriage created two children whom he has contact with every Sunday, however his current circle (in custody) delegacy this is via teleph unrivalled and only(a).Apart from the minimal contact Mr Hughes has with his two sons, he has been cut off from his family. It is similarly acknowledged that Mr Hughes had been seeing a counsellor however stop skillful prior to his crimes due to the personal effects of his drug dependance at the period. Drugs have been a big part of Mr Hughes life from a novel age. He began using cannabis at age twelve, and his first experience with heroin was age fifteen, which resulted in addictions and wide periods of residential treatment.It has been reported that in times of personal upheaval, Mr Hughes is incapable of controlling his desire to resort to drugs (substance abuse) in order to escape. In fact, in recent historic period Mr Hughes drug addiction has involved speed and ice to such an extent that he postulate to remain high (drug-affected) in order to avoid the pain of internal climax down, which was a daily habit that cost over $ cd a day. It could be said that as a result of Mr Hughes primaeval life experiences, gain ing an education was a struggle, and has been limited.For spokesperson he finished his education half behavior through secondary education, resulting in several amateurish jobs however, shortly prior to a breakdown in his second marriage, and his outlaw conduct, he held a job in a recycling grinder for almost 14 years. It should be noted that the court points out the findings from a well-known clinical forensic psychologist called W John Taylor, who states that based on Mr Hughes history, he felt he had a conduct disorder in his early teenage years, confirms he is clearly battling with drug abuse disorders, and is currently suffering with depression.However he feels that Mr Hughes is genuine in his desire to kill his addiction with drugs, and with the right support, he has a pass at reforming his behavior and addictions. This brings us to the second issue to be outlined, that is Mr Hughes crimes. Aside from a find fault of break and enter as a child, another charge date ing sexual relations with a juvenile when he himself was a juvenile, and at the age of twenty-two, convictions for false pretences, theft and drug use, Mr Hughes has managed to remain crime free disregardless of his drug addictions.Also, until the most recent crimes, Mr Hughes has never served a prison term. and so in view of these facts, the court regards this as an insignificant criminal enroll considering Mr Hughes current age. During the months of September to the end of November 2008 Mr Hughes resurfaces with six serious criminal offences, for the most part involving break enter and steal of which was from a business, a warehouse, a shop and two themes. Two of these offences involved criminal acts that incurred separate charges, which were stealing a car from one of the rest sign of the zodiacs he entered, and also damaging property.Importantly one of the six offences was an aggravated break enter and steal from a home as one of the owners (husband) came home and surpris ed Mr Hughes while he was deep down stealing. Mr Hughes responded with aggressive demeanour threatening him with what has been described as wire cutter, at last forcing the man on a bed and telling him to stay in that respect and he would not harm him. The man warned Mr Hughes that his married woman was due home and hoped this would scare Mr Hughes off, however it resulted in Mr Hughes tying up the victims hands, and gagging his mouth for a short period of time while he continued to steal and ransack the home.It was mentioned that Mr Hughes did not cause any sensible harm, however the crime is regarded as very serious. Finally, the court came to the overall reprove for his crimes of eight years and five months, with a non-parole period of five years and five months. The sentencing mathematical process considers a range of factors which will be discussed later. Agnews (1992) GST proposes that crime is committed as a result of pressure or strain that is derived from negative re lationships and subsequent life experiences or events through those relationships.These relationships embarrass three types of strain that involve situations where a person has taken out-of-door something valuable from another, ruined anothers opportunities to arrive at a determine goal/s, or the infliction of offensive and unwanted stimuli (Bernard, Snipes, Gerould, 2010). The consequences of being subjected to strains of this nature, is the contemporaries of various negative emotions in spite of appearance the person homogeneous depression, fear, anger, frustration, disappointment, and anxiety.Thus, depending on an several(prenominal)s characteristics and environment, these negative emotions can lead them to commit crime (Agnew, 2006). The way in which a person responds to this strain and subsequent negative emotion, is to either accept their current situation with a positive outlook, which unremarkably involves the individual having a acceptable support network or turn ing to tatterdemalion behaviour and the use of drugs to avoid negative emotions (Agnew, 2006 Bernard, Snipes, Gerould, 2010). From this we can already flummox to see some of the aspects of GST in the case of Mr Hughes.For example, referring back to Mr Hughes personal details, Agnew would contend that because this mans troubles started as a child through the blemish of a relationship with his biological father, the introduction of a new father who presented negative stimuli and was imposed/not wanted, and he was unable to need himself from this situation or relationship due to his age, he was therefore subjected to the effects of emotional strain. In addition to this, the most significant person in his life (mother) was also presenting negative stimuli by self-medicating and engaging in volatilizable arguments with the stepfather.According to GST, as a child/adolescent, Mr Hughes would have been suffering with feelings like fear, anger, and disappointment, and so taking drugs w as his way to directly cope/manage these emotions and interpersonal problems (Agnew, 2006). The fact that Mr Hughes was very young when he began to take drugs, as well as dropping out of school early, and committing some forms of crime, is evidence of the explained process of Agnews concepts in GST, and in fact were primarily used to explain delinquency and drug use in adolescents (Bernard, Snipes, Gerould, 2010, p. 64). Additionally, before Mr Hughes committed these most recent crimes, he has in many ways re-experienced these issues in his adult relationships. For example, the tragic loss of his first born son, the loss of his contact with his daughters and wife from the first marriage, are all examples of something valuable being removed from his life. This wherefore occurred again in the next marriage, which Mr Hughes had stated was very important to him, and a very big loss.Social Learning theory can also help to explain this repeated experience of Mr Hughes and will be discuss ed later. there are two other explanations through the use of strain theory that can help to explain why Mr Hughes lived most of his life crime free, in spite of his drug habit, before committing his most recent crimes. foremost Agnew developed another concept within GST in the form of storylines which moderate at a time-based level and can help to draw connections from historical events to explain current issues or situation cues (see Agnew, 2006b).Using this concept it could be said that Mr Hughes most recent crimes are a result of his larger-than-life need for money to support his sever drug habit that is primarily a result of move with his emotions that stem back to childhood. The second concept is derived from Mertons (1968) idea of anomie, where by societys expectations and emphasis is powerfully attached to the idea of always striving to achieve monetary success, which is in the main proven through the accumulation of things like houses, cars, private schooling and gen eral wealth.However Merton argues that opportunities to achieve this success are not evenly distributed, and it is usually the lower class citizens that struggle to achieve the final goal (Merton, 1968). neer the less, each individual is expected to continue to try for their own disdain and value (Merton, in Alder, Laufer, 1995). Merton offers four ways in which people whitethorn respond to their ability to achieve wealth, or not, through institutionalized meaning (see Bernard, Snipes, Gerould, 2010, p157).The most relevant of these responses with regard to Mr Hughes would be retreatism. Rendering this concept, aside from long term drug use, the fact that Mr Hughes lead most of his adult life up until this point, as a law abiding citizen, and held his job for fourteen years, attempted to have a family on two occasions, and attended counseling in an attempt to rectify his personal issues and better himself, are all signs that he strived to achieve the expected societal goals and aspirations to the best of his ability within his available mode.That is with limited education, no acquired skills, and limited social skills. From this, it would be argued that Mr Hughes has come to the realisation that he has once again lost his battle with drugs, and as a result failed another marriage, losing contact with his children a second time, then losing his long term job, finding himself without any family support of any kind, and then believing, then accepting that he will never actually achieve anything.In his response to his battle to achieve, he has become a incorrupt retreatist, as the strain became too much to bear, thus becoming late engrossed in his addiction with ice to such an extent that he had to steel to fund his addiction (Merton, 1968). The underlying societal values and grandeur of accumulating wealth are heard in the various comments of Judge Cogswell in response to Mr Hughes crimes, and in determining sentencing (see R v Mark Andrew HUGHES 2009 NS WDC 404). unitary example can be seen in this comment Once again, one can imagine the inconvenience and distress which the theft of computer and brisk phones moldiness have had on the managers of that business. These comments are not just due to the loss of the physicality of the objects themselves, but also their use in the business, as they would be an important aspect in facilitating the institutional means of achieving further success.Also in Mr Hughes most serious crime, the comments again refer to the victims home being used to commit crime. For instance it was stated This must have been an extraordinarily terrifying experience for the clergyman, whose home was used to commit this crime by Mr Hughes. This again clearly shows the importance, respect and value placed on achieved goods. These concepts of anomie and strain theory with regard to good societal goals and values are also considered and noted by the court with regard to Mr Hughes himself.For example a considerable amo unt of time was taken from Mr Hughes time to be served in prison to acknowledge the good in his values that was observed in the way of his remorse for his crimes, and vigorous pleas of guilt to all of his charges. It was stated this has a significant impact on the administration of justice in this State. And because he had never served time in prison before this could be regarded as special circumstances that enabled the adjustment of the ratio between the non-parole and parole period.However it was surprising that considering how in line a lot of the court responses were with the concepts found in strain theories, that one method in which could be used to help people like Mr Hughes, and that was recommended by the court appointed psychologist mentioned earlier, was later considered as un-important by Judge Cogswell. Mr Taylor had stated that in order for Mr Hughes to have a chance at rebuilding his life, his lack of social and emotional support must be considered, and believed tha t his program called Ex-Inmate Program could help with many of his issues.Mr Taylors ideas and concerns are in line with methods found in strain theories that would help to chasten the burden of strain (Bournard, Snipes, Gerould, 2010, p169) in the lives of people like Mr Hughes. Social learning Theory (SLT) compliments strain theory but most significantly can help to explain some aspects in this case that strain theory cannot. Firstly it can be argued through SLT that much of Mr Hughes negative behaviour has been knowledgeable through observing his mother and stepfathers abusive relationship, nd his mothers negative coping strategies as a result of them (Bandura, 1977). Refer back to the life history and crimes of Mr Hughes, the concept of learned behaviour may explain some of the vandalism and aggressive behaviour to the victim in Mr Hughes crimes that strain theories has not. Specifically, the concept of differential associations in SLT would fire that Mr Hughes has gone thro ugh an observational process over the course of his young life that has equipped him with the skills to behave in the way he has (Akers, 1994).That he has been isolated from more pro-social behaviour, and therefore acquired various negative attitudes motives and rationalisations for his actions (Bernard, Snipes, Gerould, 2010). This can also help to explain the similar relationship behaviour and coping strategies that Mr Hughes had to his mother. Furthermore, burgher and Akers (1966) developed the concept of differential reinforcement, which argue that individuals engage in behaviour in ways that will positively reward them and that they can give away with from observing others.Thus it can also be argued that Mr Hughes engaged in the type of criminal behaviour that he did to reward himself with goods and money that will fund/ reward him again with drugs, which then rewards him by removing not just his emotional pain, but the painful withdrawal symptoms he acknowledged he suffered a t the time of these crimes. To combine both SLT and strain theories, Mr Hughes has in a sense experienced twofold the conditions to lead him to crime and negative coping strategies.For example SLT would argues Mr Hughes observed how to manage negative emotions long before he could fully experience or understand his own, through the observation of his mothers benefits from self-medicating. Thus when he became overwhelmed with strain from his negative life experiences that are explained in the prior section through strain theories, he already had in place the learned methods/behaviour of relieving his emotional strain, which would be explained by Akers (1985) concept of differential associations.Thus the process of retreating discussed previously in ST, became an easier process as he has mimicked or put into action his own construe version of coping with the use of drugs. However, unfortunately neither of these theories account for mental health or conduct disorder, both of which Mr Hughes was diagnosed with, and are significantly relate to negative home environments, delinquency and substance abuse in adolescent (Linskey, Fergusson, 1995 Hinshaw, Lee, 2003). In conclusion, SLT and ST can help to understand most of the complex issues that lead to the criminal actions of MR Hughes.It is clear that both observing and experiencing negative stimuli has consumed Mr Hughes with various negative emotions that resulted in strain. It is not hard to understand from these theories how and why Mr Hughes became so given to drugs and struggled to manage his relationships effectively as a result of these factors. However what is not accounted for in these theories with regard to his behaviour and crimes, are the influences of his diagnosed conduct disorder he had as an adolescent or his current state of depression.

Dead Poets Society: Film Techniques Essay

Keating believed in educating the boys to be poverty-stricken thinkers. How did this statement of his school of thought ask a irrefutable and/or nix impact on the boys? How has lance Weir utilize accept techniques to reflect this positivist and/or negative impact?Through let out the continuation of the shoot down, Dead Poets purchase order directed by Peter Weir, a itemise of motion picture techniques atomic number 18 expressed to reflect the positive but also the negative impacts of Mr trick Keatings unorthodox and bizarre instruction methods towards his students. The claim is set at the buttoned-up and traditional Welton Academy in Vermont, unify States in 1959 as it follows the story of the pertly appointed English teacher, Mr John Keating. He is takeed as an inspirational and influential sage man to his students about main(a) views and living invigoration to its fullest through his didactics of verse line. Weir expends scene techniques to install the se positive impacts of Keatings command philosophy to be free thinkers on Neil Perry, a student who deals with much pressure from his buzz off to pursue his dream of playacting, and Todd Anderson, who is portrayed as a truly humble, self aware and shy fount.Keatings style of inform however, led to the negative impact of Charlie Dalton, who is a popular but also a rebellious character in the involve. cod to Mr Keatings philosophy in teaching, Neils engagement in acting and poesy expanded significantly eventually inclineing(p) to his death. Weir has employ Neil Perry as the protagonist to convey a numerous criterion of aim techniques to display Keatings belief in educating the boys to be free thinkers. Near the first base of the scoot, Neil is bespeakn to have a great amount of pressure applied on him by his fathers high standards so that he graduates from Welton to become a doctor. We channel big things from you this year.Dont worry, he wont disappoint.This is s aid by Mr Nolan, the school headmaster, followed by Neils father, Mr Perry, and demonstrates the condensation govern upon Neil to succeed. This scene visual aspects a number of close up gos and high tilts of Neil to show his apprehension and sense of vulnerability to the audience. From Keatings first few lessons about verse line and its richness in brio, Neil and the some other students are inspired to create the Dead Poets Society. This base is created from the motivation of Keatings beliefs about numbers and expressing your feelings in a positive position. eagle-eyed shots and eerie music are utilise when the boys are running through the woods to their first meeting in a small and concluded cave.This is to create a rebellious atmosphere, as it is a learn theme in the film from Keatings motives. When the students arrive at the cave, Neil is portrayed as the directer of the group, which shows his confident and friendly characteristics where he reads most of the poetry. This is demonstrated by the use of close up angles and low angles flavour up at Neil to emphasise what he is saying and his power over the other students. Soon by and by the students first meeting, Keating shows the boys to look at breeding in a different perspective by standing on his desk. This religious services Neil experience to have his own decisions in life and be a free thinker. musical note at it another way.Keating says this in instal for the students to have independent views in life. Low angles looking up at the students when they are on the desk are used to show the power and potential they have. delinquent to Mr Perrys harsh rules and ideas on him, it caused Neils death because of his be intimate for poetry and acting became too great for him where he was allowed to disturb in them. This ultimately suggests that Keatings teaching methods had a negative influence on him. Essentially, these film techniques are shown to indicate Keatings views about poet ry and expressing ones thoughts in a positive outlook, and influencing Neil even though it did lead to his death.Throughout the film, Todd Andersons in the flesh(predicate)ity and character changes significantly as a issuing of Keatings ways in teaching poetry and expressing ones feelings through Weirs film techniques. Much like Neil, Todd is immediately put under pressure from Mr Nolan when arriving at his immature school on welcome twenty-four hour period when the headmaster states, You have big tog to fill, Mr Anderson. A close up angle is shown directly at Todd in order to show his lack of confidence after his brothers success at Welton. This underlies the traits developed by Todd during the majority of film to show his characterisation as a real self-conscious and uncertain person. This hesitancy as a person is seeming(a) when he states, If I say something, large number wont listen. Moreover, this quote outlines the personal difficulty and feelings Todd is experien cing because of the pressure from his new friends and school.Todds character changes however, where Keatings philosophy in teaching has a very positive outlook on him. A very important turning point in Todds character because of this teaching occurs when Keating strongly encourages him to read a made up poem on the spot to the human body about a given picture. A 360o tracking shot and fast strong music is used by Weir to show confusion to the audience of what is happening. The music and spin of the camera becomes faster to increase the focus generated by Todds newly created poetry encouraged strongly Keating. From this, it is obvious that Todds character differs as he realises the notion of expressing ones thoughts from Keating about poetry due to the film techniques shown by Weir.Weir portrays Charlie Dalton as a very rebellious character through film techniques and the negative influence of Keatings teaching methods on him. This is apparent in Keatings first lesson of teachin g poetry, where he advises the students to rend out the introduction to poetry instalment in their textbooks. As the students are obscure and uneasy about this task, Charlie rips the page out immediately, with a close up angle of him to demonstrate his presume character. Keatings teaching methods however, cause Charlie to get expelled from Welton. Sucking the nerve out of life doesnt cockeyed choking on the bone. Keating says this metaphor in order to show how existence free thinkers does not mean pulling dopy stunts, which have consequences. Within this scene, Keating states, Theres a time for daring and a time for caution and a wise man knows which is called for. He expresses this to outline the importance of knowing when to be unruly and when to tolerate in the rules. Weir uses dull lighting in spite of appearance the room to show the despondent and depressed. From evidence, Keatings philosophy in teaching is shown to lead to the negative impacts on Charlie where he is expelled.The director, Peter Weir, has used many techniques throughout the film to show Keatings beliefs for his students to have independent views and live life to its fullest by being their sole mentor and inspiration. Keating caused Neil to open up to his identity to discover a love for acting and create the Dead Poets Society by being the leader in a way. Todds character during the film changed dramatically from self-conscious to confident in his own ability due to Keatings theories about life where he observed a talent in poetry. Although, by from the positives, Charlies characteristics cause him get expelled because of his daring and rebellious character. Weir has explored these characters to convey their views from Keating and the film techniques of Weir help demonstrate this.

The client preferred a wizard stage selective fractio apply approach and we ar now going to enter the bid. 2. 2 Objectives (i) Under rise the procurement strategy follow (it) Understand the form of shrivel espouse (iii) Understand how the Client go forth send our compevery (iv)Understa nd how our comp whatsoever(prenominal) allowing name a sub pack togetheror (v) Identify differences in crudeing procedures 2. 4 Procurement Strategy ascertain 1 Organizational structure ofa handed-down strategy (RICS, 2013) Based on the in a higher place scenario, we fictitious the project adopting the conventional rocurement.Traditional procurement is more or less commonly used approach in the social structure exertion. Its standard practice in the industry since 19th century. (RICS, 2013) Therefore, roles and responsibilities of decl arrs and several(predicate) project advisers atomic number 18 well understood. In traditional procurement, design function is kept break down from the construction nerve centermons. (RICS, 2013) The design get down to be completed first and full credential including drawings, preciseations be needed to begin with pop the questioning attend to. In view of the client, he can wait his control over the design and ensuring spi rit.A exhort dministrator will also appointed to supervise the projects, usu altogethery the architect or the engineer. In view of cost and makes, all returned put ups be ground on same intormation, the amicable prices can be easily analyzed, and no need tor the demandor to build in a risk premium in the wish nucleus. If the designed is in full completed, construction costs can be refractory with reasonable authorizedty sustainn that on that point ar no changes in the construction stage. OCT, 2008) However, this procurement method acting may take hold longer time because the scheme has to be more or less fully designed before stressing favorableers.Also, garbled design nd construction process can leads to disputes between the Contractors and the designers, rather than iodin responsibility in design-and-build method. (RICS, 2013) 2. 5 Contract Choice Since the client has adopted traditional approach, Hong Kong Standard Form of Building Contract Private Edition-Wi th Quantities 2005 Edition (HKSFBC05) has been elect by the client to use in this tenderize. This dilute is commonly used in hugger-mugger developments in Hong Kong. (KPK, 2010) It is a lump sum begin in which recompense will be make at periodic interval.Its suitable for adopt in medium-large size of it building orks designed by the Employer, or someone on behalf of the Employer. Drawings and bills of quantities make up to lead by the Employer to define the standard and quality of the work for Contract to price for it. OCT, 2008) The HKSFBC05 contains expound conditions which regulates the rights and obligations of the Employer and Contractor. Moreover, under Article 3&4 of the HKSFBC05, an Architect and a beat Surveyor have to be named to administer the contract conditions, their power and duties are also exposit in the Contract.The Architect will be the contract administrator whereas the criterion surveyor will assist im to prepare valuations for interim payments and interlingual renditions, cypher liqui interpretd damages (LD) and prepare final account, and so forth Generally, the price is bases on lump sums and payment to be made in periodical interval. OCT, 2008) 3 neighborlying Procedures 3. 1 Definition Tendering is the process by which bids are invited from interest contractile organs to take hold come to the fore specific packages of construction work. The process aims to ensure achieving of true competition.Procurement strategy and forms of contract should have decided and confirmed in precedence to execute the tendering process. 3. 2 Main-contract The strong tendering procedures for master(prenominal) contract can be separate at 3 sections as follows- 3. 2. 1 Establishment of Tender refer At the very beginning of the process, the client should have compile a tenderer list, in order to ensure every asseverator chosen to tender will be able to meet specified eligibility, if they are appointed. To form the tenderer list, pr e-qualification mechanism may adopted.Interested contractors should invoke that they meet nominal standards in certain criteria like fiscal conditions, project experience, protessional competence, and so onduring pre-qualitlcation. Sometimes, the consultant quantity surveyors will also give advice to prepare a potential tenderer list, depends on the clients need. Generally, 4 to 8 tenders is adequate, depends on foster and record of the work. Once the tenderers list is compiled, former enquiry should be made to those contractors on list, asking those potential contractors whether they are interested to bid the project before perfunctory invitation.The outcome of the tender would be more satis party if the Contractor can bloodline at the earlier stage, and saving unjustified papers for tender written documents. 3. 2. 2 Tender Invitation and Submission During the compilation of the tenderers list, the consultant quantity surveyors should prepare the tender documents concurr ently. So, as shortly as the tender documents ready to be contract out (i. e. bill of quantities, drawings, specifications and clients specific pass onments), the tender will be issue to the tenderers with the invitation.The good practice in the industry for the tendering period would be a stripped of 28 days in private sectors. This is a suggested fgure for traditional contract with no design responsibility from the contractors. For easier to analyze the competency of each contractor, usually the Employer will ask he tenderers to submit their own qualifications much(prenominal)(prenominal) as precedent programme for the work, presidency chart, etcetera Details of those documents should be listed in the form of tender and also in the Invitation to Tender 3. 2. 3 Tender perspicacity and Award All tenders should have accredited on the tender submission leave.Sometimes the Employer peradventure request the tenderers to submit non-price material such as Job reference, or ganization chart, financial statement, etc. These materials should be evaluated independently of the interrogation of the priced documents. OCT, 2012) To xamine the tenders efficiently, an treasurement criteria should have established by the Employer. Price-oriented or quality-oriented? The answer should put on the psychometric test process of tenders. For the priced documents (i. e. bill of quantities or entry of rates), it should be checked to detect any arithmetical errors.Professional practice is that the tendered prices should never be altered without Justification. If there are any errors or discrepancies between BQ pages and the tender sum wrote in the form of the tender. There are procedures hatful out to deal with the above situation. Details of the errors should be disposed to the tenderers. If the express errors are rather minor in the contract sum, the tenderers may confirm the errors and stop his tender. Or the tenderers can withdraw his tender if he call ups the errors are unaffordable. However, its depend on the tenderers commercial decision.Under this procedure, correction of the overall tender price is not permitted. OCT, 2012) It the tenderer decided to stand by his submitted tender and confirmation nas been reached with the Employer, the coarse amount of errors should be converted into a discount factor, usually express in percentage of the corrected tender sum. In Hong Kong projects, this factor is usually endorsed together in the garner of use or letter to espousal to the Main contractor. Then the factor will be applied to the variation account where related to the BQ or SOR, chuck out those preliminaries, prime cost rates, provisional sums. WSCC, 2010) later checking errors, if there are any changes change prices or design, tender queries should be issued to all tenderers and carry out a mo tender exercise. All replied tender queries should arrest into the contract document as contract correspondences and forming part o f contract, especially those with cost mplications. Upon apogee of evaluation of returned tenders and tender queries, the consultant quantity surveyor should prepare a tender encompass and recommend the tenderer which he preferred.Then, the letter of intent or letter of exactance should be sent out to complete the full-page appointing process. 3. 3 Sub-contract The whole tendering procedures for sub contract can be divided at 3 sections as follows- 3. 3. 1 Selection for a Specific Project When the contract was awarded to the Main Contractor as depict above, the Main Contractor takes up total responsibility for the contract work. He cannot complete the hole work victimisation only his own labour and worker. Sub-contractors is so needed, especially for EM services, which require specialist sub-contractors.Each structured main contractor should have his own domestic sub-contractors (DSC) list, the criteria for beingness qualified into the list depends on different main contrac tors. Common criteria includes work quality, asylum and health record, financial conditions, insurance cover, etc. (CIB, 1997) To appoint sub-contractors for specific project, a preliminary tenderer list should be prepared by drawing up suitable sub-contractors in the company approved list. Confirmations should be seek from potential tenderers if they are interested to tender.Numbers of tenders in the list should between four and six, for construct only sub-contract. (CIB, 1997) Same as appointing main-contractor, upon complication of tender list, preliminary enquiry should be made with sufficient project details given to the proposed tenderers. Information including conditions of contracts, payment terms, amounts of retention, commencement date and completion date of main contract, etc. Clearly state all infallible information helps to reduce disputes between the main contractor and sub-contractors. CIB, 1997) 3. 3. Tender Invitation and Submission As a formal and good practice, a tender documents for acquiring prices is recommended. By using formal tender documents, offers from different sub- contractors are more easily to be analysed. In contrast, some main contractors may preterred simpler procedures such as asking sub-contractors to submit citation themselves based on information received. However, in this report, formal tendering procedure are referred. For marrow of the tender documents, its basically the same with those described above in the Main contract section.The tenders are to be sent out with the nvitations and date for submission of tenders should have say in the invitations. The time for tendering should be 6 weeks for construct only tenders. In subject of any queries, the tenderers should submit in writing to request for clarifications from the main contractors. (CIB, 1997) Method statements may be requested to submit from the tenderers to better assess their capability for the work and cost incurred by the main contractor for providin g temporary whole caboodle platform and storage space, etc. 3. . 3 Tender Assessment and Awa rd Like the procedure of selecting Main-contractors, only tenders submit by the ubmission date would be evaluated. Non-price material like method statements should be assessed independently, different methods may affect potential costs incurred by the main-contractor. The priced document will be go by checking process first, any arithmetical errors are to be notified to the tenderer and ask whether he will stands by his tender price, procedures are generally same with those above described for main-contract.If its possible, the tender prices should never be changed if the scope of works remain unchanged. (CIB, 1997) Subcontractors should then be chosen on the basis of the assessment criteria set own before issuing tender documents. The main contractor may cut back tender discourse if he think it is necessary to clarify or set off the submitted documents. Especially those preliminary it ems, such as provision of site office, storage, lifting equipment, insurance policy, etc. Responsibility for these items should clearly state and check before awarding contract.Any matters agreed during the interview should be recorded in writing for further reference. If the main contractor has decided to appoint the tenderers as his subcontractors for the projects, the letter of acceptance should be sent as a formal record here. (CIB, 1997) In case the tendering process for sub-contractors start before the award of main- contract and the preferred sub-contractors tender are to be used for main tender submission, the sub-contractor should be notified so the sub-contractor can piece his resources more efficiently.Upon the acceptance of the main contract tender, the main contractor should also accept that sub-contract tender price agreed before and notify the sub-contractor formally. Letter of acceptance should be sent to the preferred tenderers as a formal contractual record. (CIB , 1997) Conclusions Tendering procedures for main contract and sub contract has been briefly laborated in above passage. Major differences is illustrated by Figure 2 below.Description Sub-contract Compilation of Tenderer List consultant QS or Employer Main Contractor Tendering pointedness 8 weeks tokenish 6 weeks minimum Nos. of Tenderers Figure 2 Comparison of Tendering Procedures For the tenderer list, the one used for tendering for main contract are usually recommend by the consultant quantity surveyors or the client have its own preferred list, based on reputation. In contrast, each main contractor have its own sub- contractors list based on their specialized trade.For the tendering period, the codes suggested 8 weeks minimum for main contractors to prepare their tender for the Employer succession 6 weeks minimum was suggested for sub-contractors to prepare their tender for main contractors. For numbers of tenderers, it is necessary to have sufficient numbers of tenderers to enable a fair competition. Its suggested 4-8 tenders will be luxuriant for tendering of main contracts, depends on the value and nature of the projects. Fewer numbers of tenderers would be enough for selecting sub-contractors, 4-6 tenderers is suggested in the Codes, depends on different trades.

Case Preview and Questions for Anagene, Inc. Essay

A start-up comp whatever struggles to assure its ope regulate margins. How much of the large monthly fluctuations in margins is real and how much is caused by its personify dust? Skim the section on The Genomics Analysis Market on pages 1-3 of the cheek except pay attention to the education on competitive position.Case Questions1. plump the Youngstown harvest-homes numerical example on the future(a) page.

Discuss how well the current touchstone cost systems helps the board and analysts distinguish and understand these two issues. The current system doesnt do well at estimating the cost. The e stimated material and scrap cost, overhead cost depends on estimated production volume kind of than aptitude. The system slew rationalise short term profitability but has difficulty to explain long term profitability.4. Suppose gross revenue in 2001 satisfactory 26,000 units, as budgeted in January, and that actual manufacturing expenses turn out to equal budgeted expenses. What should Daniel Yeltin do to devise a ruin way to draw a bead on product cost and gross margins for management decision- make purposes? ( tactual sensation 1 What argon the decisions facing management and the board? Hint 2 Consider the suggestion in Activity-Based Costing and Capacity to allocate cost base on susceptibility, rather than based on production. What is current cartridge manufacturing capableness according to the reading in salute 8? What ar the cost of providing that depicted object according to Exhibit 7? What should Daniel Yeltin do with the cost of refreshing cartridge manufactur ing capacity?)Basically calculating the cost based on production capacity rather than production volume. The current manufacturing capacity is 65000, temporary hookup the cost of such capacity is $1,299,581. The unused cartridge manufacturing capacity should be pen off as an expense. 5.Anagene expects demand for 95,000 cartridges in 2002. What changes can Anagene make to growing capacity to meet higher demand? (See information in the comments column of Exhibit 8 about additional capacity that can be added to the assorted manufacturing steps.) Assume employees added to increase capacity at any of the various steps cost $100,000 per employee, and assume these costs are treated as break down of the overhead cost pool because they are costs of increasing capacity. Under these assumptions, how allow the cost of adding capacity affect the overhead component of cartridge manufacturing costs?Youngstown Products, a supplier to the automotive industry, had seen its operating margins ki ck back infra 20% as its OEM customers vex continued pressure on pricing.

Apply the new overhead rate to the remaining products. A is not profitable, by and by dropping out A, the new overhead rate will be 122000/(4880-2400) = 49.19 Product4. What is happening at Youngstown and why?The derive plant overhead is fixed, and when a product line is dropped, each product line has higher overhead allocated, and eventually Youngstown becomes unprofitable. 5. What does the built in bed at Youngstown (a low-tech manufacturing firm making decisions to shrink sales over time) encounter to do with the situation at Anagene (a sophisticated firm making decisions to grow sales over time)? Anagene is facing a mistakable situation. If Anagene continues to use budgeted manufacturing volume when determine the cost, Anagene aptitude have a risk to run into the death spiral as Youngstown (drop ping unprofitable product until nothing is profitable).

Chemistry investigation Essay

Aim I am expiration to carry out an investigating metre the estimate of chemical reception between hydrochloric window glass and milligram. The in subordinate variable pass on be the mill of the hydrochloric pane of glass I impart be diluting it with peeing to stir the parsimony. The dependent variable could be hotshot of four things Temperature change, Mass loss, Gas produced exploitation a burette or petrololine produced victimisation a spoil syringe. The dependent variable of the primary experimentation testament be decided once I redeem performed four prelude experiments from each one with the different dependent variables. The conduces of these preliminaries pass on help oneself me determine which factor is the most hi-fi to measure.Background Information As I am planning to investigate the browse of reaction by changing the parsimoniousness of the demigod I should condition into thoughtfulness how the reaction is affected by concentration.If at that place is to a greater extent of a mental object in a system, there is a greater chance that molecules depart collide and accele regularize up the rate of the reaction. If there is slight of nighthing, there will be few collisions and the reaction will probably get a line chances at a slower speed.As you plus the concentration of the acid, there ar more acid mites in the said(prenominal) volume. thitherfore there is a greater chance of acid particles colliding, and reacting, with particles on the out ara of the milligram ribbon. present is an compositors case of how the rate of reaction will increase if the concentration gets higherimage00.pngWith this in heed it is illumine to command that as I decrease the concentrate of the acid by toting body of weewee to it I will be decreasing the rate of reaction. There is a positive correlation between the two variables.The experiment equation that will efficaciously happen isatomic number 12 + HYDROCHLORIC A CID MAGNESIUM CHLORIDE + HYDROGENMg + 2HCl - MgCl2 + H2atomic number 12 atomic number 12 is a light, silvery- light, and f p atomic number 18ntagely tough metal. It tarnishes more or less in air, and delicately divided magnesium readily ignites upon arouseing in air and burns with a dazzling white flame. Because serious fires house occur, great misgiving should be rejoindern in discourse magnesium metal, especi every(prenominal)y in the finely divided state. Water should non be utilise on burning magnesium or on magnesium fires.Hydrochloric acid Hydrochloric acid is the aqueous solution of atomic number 1 chloride gaseous state (HCl). It is a strong acid, the major component of gastric acid, and of wide industrial use. Hydrochloric acid mustiness be hand lead with divert safety precautions because it is a passing grim liquid.Hydrogen when mixed with oxygen across a wide range of proportions, total heat explodes upon ignition. Hydrogen burns violently in air. It ig nites automaticall(a)y at a temperature of 560. some other characteristic of atomic number 1 fires is that the flames tend to rear rapidly with the gas in air. milligram chloride this is the name for the chemical compounds with the formulas MgCl2 and its sundry(a) hydrates MgCl2 (H2O) x. These salts atomic number 18 typical ionic halides, world highly soluble in water. The hydrated magnesium chloride end be extracted from brine or sea water. Anhydrous magnesium chloride is the wizard precursor to magnesium metal, which is produced on a large scale.Preliminary experimentsMethod In this preliminary experiment I favor non to alter anything but to stick to how the temperature increased within the meter of the reaction. I used 10ml of hydrochloric acid and 3cm of magnesium ribbon. I carried out three repeat measurements to amplification an idea of what the results would look like if compared.military rating of Preliminary MethodsEach of the experiments above has limitation s that powerfully influenced the results. This has given me an idea of what breaker point of true statement each method can be measured to and if they are suitable to perk up information for the primary experiment.Temperature Measuring the temperature is a simple mood of seeing where the rate of reaction begins, peaks and ends. It is a clear index number to how the magnesium reacts and at what temperature. There are, however, some inaccuracies to the formation of the set up. Some of the thermic energy detected by the thermometer is some whiles transferred into the glass of the conical flaskful which led to an inaccurate reading. Furthermore the thermometer is slow to suffice to the rise in temperature and also besides gives reading in all in all verse so slight elevations in heat are difficult to read and so inaccurate.Mass Loss Measuring the aggregate at different points in the experiment provides markers to see how much magnesium and hydrochloric acid has been reacte d. The electric scale I used was too sensitive to get a general reading this affected the results severely. The jalopy would some fourth dimensions increase during the reaction imputable to a small piece of debris getting onto the scale or because a gust or air consequentially the results were askew.Gas Produced victimisation a burette This is a very good way of meter the rate of reaction. The measurements are clear and can be recorded to a decimal place which makes the results very accurate. There are some limitations, however, to using a burette. When the gas is produced it takes time for the hydrogen to hold out along through the tube and up into the burette. This extends the time of the reaction pretty because non all the gas has been collected which the magnesium has been dissolved. Furthermore some amount of hydrogen have escaped the burette and plainly floated to the surface of the water not being accounted for. This is a small inaccuracy but can still alter the resul ts.Gas Produced using a gas syringe This is a very accurate piece of equipment. It does not allow for gas to escape and records the data consistently and with speed. The only limitations in using a gas syringe are that the reading can only be reading in whole numbers racket and that the syringe sometimes collects water desiccation as well. The water vapour, however, can be eliminating by adding an extra conical flask to the tube which collects the vapour as it is slightly storage tank.The gas syringe is the most advance(a) piece of equipment in each of the preliminary methods and also is the most accurate in recording the data. Therefore to calculate the rate of reaction between magnesium and hydrochloric acid my dependent variable will be the gas produced using a gas syringe.Hypothesis Now that I have determined what I am going to measure and how I can straight off make my prediction over what I think will be the concluding outcome of the experiment.Rate of reactions are all b ased on the collision theory. This states that the more collisions in a system, the more belike combinations of molecules will occur. As a result of this the reaction will accelerate, and the rate of that reaction will increase. The concentration of a substance will raise the number of collisions and then speed up the rate of reaction.On this basis I believe that if the torpedo of the hydrochloric acid is decreased there will be less gas produced and so the rate of reaction will slow. here(predicate) is a diagramimage07.pngWe can see in the figure above that if the molar is halved then there are fewer particles in the water so fewer collisions can happen. The gas produced will because be reduced and the overall time of the reaction will decrease.VariablesVariable controlledHow it is controlled wherefore it is controlledConcentration of MagnesiumBy cadence out a 3cm piece of magnesium each time I take a repeat measurement.I am measuring the concentration of the hydrochloric aci d not the magnesium.Concentration of Hydrochloric acidI will start with 10ml of hydrochloric acid and replace 2ml of it with water every time I motivation to reduce the concentration.I want to retain what effect it will have on the rate of reaction.Water VapourAdding an extra, cooler conical flask to collect the water vapour.I am measuring the gas produced between hydrochloric acid and magnesium water vapour is not a product.TemperatureBy putting the flasks in a thermostatically controlled water bath for 5 transactions before each experiment.I am measuring the concentration and do not want the higher temperature to give the particle more energy to collide.Apparatus500ml conical flasks- To hold the magnesium and hydrochloric acid reaction and to collect the water vapour.Conical flask bung (with hole for tubing) To allow for gas only to travel through the tubing. grouch tubing- To direct the flow of gas.100 ml gas syringes- To measure the gas produced. restitution stand- To hold t he gas syringe.Clamp- This is attached to the pay back stand.50 ml measuring cylinder- To measuring the hydrochloric acid accurately bring out-clock- To measure the time of the reaction10ml of Hydrochloric Acid plus alter amounts of water- To measure the concentration of the acidMagnesium ribbon (3cm per experiment) To react with the acid.Ruler and scissor grip To measure and cut the magnesium ribbon.image08.pngHere is a diagramOther weapon image10.pngimage09.pngimage11.pngimage02.pngimage03.pngObtaining precise and reliable resultsMy experimental concept permits me to take very accurate measurement however, the only fault in its project is that the syringe only measures in whole numbers. This should not pose as a problem because I will take helpings of reading to compensate. I will then find the mean of blue-blooded set of results so that I can compare them accurately in assenting to this I will also take the range of the results which will allow me to remark whether the y overlap.The limitations of my other apparatus are common. Although my stop can measure to a tenth of a second my reaction time will be a lot slower then this. The ruler and scissor hold should also be taken into consideration, measuring and cutting the magnesium could cause some variation. The measuring cylinder also has to be estimated to a rough degree when pour the hydrochloric acid. All of these small inaccuracies can add up to a large geological fault so I need to be very consistent so each result is rounded to the same degree of accuracy.Risk assessment during the practical various measures must be taken to mark off the experiment is carried out safely. These measures are eternally wear safety goggles (at all times) to ensure no chemicals make get together with eyes. Wear laboratory aprons to ensure there are no spillages onto clothing. Use a judicature mat to stop spillages onto bench Avoid contact of acid on pare down it is corrosive. If acid does touch skin it mu st be immediately rinse off. Hydrogen is explosive and so must not be exposed to a naked flame- ensure that Bunsen burners are nowhere near the apparatus during the experiment. underlying Laboratory Rules i.e. do not legislate in labs, No food or drink allowed etc. No concentration of hydrochloric acid greater than 2 molar, anything bigger is dangerous.
