Critically evaluate the application of Edwin Sutherlands theory of differential association to contemporary criminology - Essay Example ural amalgamation and incorporation came into being, and the crime rate also got its place along with the growth of civilisation with an upward trend and increase. With the passage to time, methods of protecting the society from criminal assaults were taken into consideration. Human societies established political authorities, which introduced laws and rules for keeping the societies in perfect order on the one hand, and for protecting the people from criminal assaults and harms on the other. Hence, boundaries lines were drawn between normal and criminal behaviour. â€Å"The vast majority of the rules†, Sutherland & Cressey state, â€Å"which define certain behaviour as criminal are found in constitutions, treaties, common law, enactments by the legislators of the state and its subdivisions, and in judicial and administrative regulations.† (1970, p. 5) Researches were conducted and theories were articulated in order to discover the real reasons and motives behind committing of crime and getting involved into perversion and deviant behaviour. Nature-nurture theories appeared for further debate and discussion on the topic of the reasons behind people’s getting involved into criminal activities and delinquent behaviour. Some of the theorists believed that innate characteristics are dominant in personality traits, which determine the future behaviour of the individuals. â€Å"Concrete behavioural traits,† Pinker submits, â€Å"reflects the underlying talents and temperaments—how proficient with language a person is, how religious, liberal or conservative—are partially heritable.† (2004, p. 5) On the other hand, another school of thought vehemently declared crime as a learned behaviour. According to this school of thought man is born with pure heart and mind, and it is social environment that spoils a nd detracts the individuals from the right track. Sutherland insisted on the theory that crime is absolutely a learned behaviour, and people learn and adopt criminal

The History of Cell Theory in the Last 200 Years Essay Example for Free

The History of Cell Theory in the Last 200 Years Essay The last two centuries present significant advancement in the study of cell development in biological science since the term was first coined by Robert Hooke in 1665. Although Hooke first observed the presence of cells in matters it was Jean Baptiste De Lamarck (1744 1829), a French scientist, who initiated early steps in recognizing the concept of the cell as a biological element in living things while carrying out extensive works in evolution and classifications in the animal kingdom. This is similar to the Rene Dutrochet’s pronouncement in 1824 that the structure of a living body’s fundamental elements is the cell, created through the process called juxtaposition or combination, producing both animals and plant forms. Several assumptions followed which serves as basis for the modern cell theory including Ludolph Christian Treviranus’s (1779-1864) proposition that a cell can be further separated into even smaller components by its intracellular space or individual units comprising the cell itself particularly in plants. Building on this concept, Robert Brown (1773-1858) published a paper naming one of these units â€Å"cell nucleus† in 1883. Although scientifically accepted as fact today, Brown together with Bauer, at that time, never thought the idea of cell nucleus to be universally present in all living things and limit the concept to monocotyledons (also called monocots), one of the major groups of angiosperms or flowering plants. Amidst the numerous assumptions and differing opinions of their times three names excel in the field of cell science: Theodor Schwann (1810-1882), Matthias Jakob Schleiden (1804-1881) and Rudolf Virchow (1821-1902). Schwann discovered what is called Schwann cell or neurolemnocytes, glial cells supplying vitality to peripheral nerve fibers. Together with Schleiden they concluded that all living things are composed of cells and published their findings in a paper called Microscopic Investigations on the Accordance in the Structure and Growth of Plants and Animals. Almost their contemporary, Virchow further improved the idea into a wider and more scientific scale stating that cells come from cells of the same kind, refuting the theory of Spontaneous Generation. Virchow was also one of the very first scientists to apply existing cell theories together with findings he himself formulated in medicine that led to the discovery of leukemia cells and a deeper understanding of lung cancer and other deceases related to cell formation and their behavior. In 1855, Virchow states that cells replicate through the process called â€Å"cell division†. Together, Schwann, Schleiden and Virchow are the three considered to be the key figures and originator of the basis for the concepts of modern Cell Theory. Development in the Cell Theory in the 1900’s is not as numerous as that of the 1700’s and 1800’s. One discovery, however, worth mentioning is the finding made by James D. Watson and Francis Crick regarding the double-helix structure for DNA in the 1953. 2. Membranous Organelles of Eukaryotic Cells †¢ Chloroplast (plastid). Chloroplasts are present in eukaryotic a cell which main function is to capture light energy to conserve free energy in the form of ATP moderating Nicotinamide Adenine Dinucleotide Phosphate (NADP) and requires NADPH as a reductant in a reduction-oxidation (redox) reaction. †¢ Endoplasmic Reticulum (ER) forms the network of tubules, vesicles and cisternae in cells necessary for protein synthesis ( the process where cells proteins), protein folding and transport, secretion or exocytosed, and manufacture and storage of glycogen, steroids and macromolecules. †¢ Golgi Apparatus or Golgi Complex deals with the processing of proteins and lipids after synthesis before transporting (e. g. secretion) †¢ Mitochondrion generates the cell’s energy (i. e. chemical energy) and produce majority of its Adenosine Triphosphate (ATP) †¢ Vacuole is an enclosed water filled compartment within a cell containing enzymes and various natural and inorganic molecules. †¢ Nucleus contains majority of the cell’s genetic materials organized in a multiple long linear Deoxyribonucleic acid (DNA). It is considered to be the cell’s control center. 3. Methods in Molecular Exchange †¢ Diffusion. Diffusion balances the degree of concentration of molecules from a region with higher concentration to a region with lower concentration as a reaction to thermal motion. It plays a vital role in the distribution of oxygen, nutrients and other molecules across the capillary walls and across membranes. An diffusion equilibrium is said to be attained when the amount of molecule between two regions are equal and no diffusion movement occurs, or the net flux is at zero rate. The degree of concentration, temperature, and room affects the direction and extent of net flux related to the process. †¢ Endocytosis. Endocytosis takes place when cells suck up molecules from the outside of the cell by swallowing it up using their cell membrane. †¢ Exocytosis. Exocytosis is the reverse process of endocytosis where a cell releases the contents accumulated by the secretory vesicles out of the cell membrane. 4. Catalyst and Enzyme Catalysts are substances that make a chemical reaction faster than its normal rate. Catalysts inhibit changes in matters acted upon (substrate) but remain unchanged on the final output of the reaction (end product). Enzymes are types of catalyst that are almost always in protein form and are used in biochemical (living) reactions. 5. Enzyme-Controlled Reaction During an enzyme-controlled reaction, the enzyme’s key portion called â€Å"active site† interacts with the substrate. The substrate begins reacting to the enzyme entering a stress state. Upon reaching the necessary stress rate, the substrate changes in form or state (or both) producing the end product. The resulting end product is said to â€Å"drift away† and the enzyme is then free to perform the same procedure in the chemical reaction until no reactible substance is left, concluding the process. 6. Enzymes, Coenzymes and Vitamins The primary function of vitamins in living organisms is to serve as cofactors for chemical reactions involving enzymes. Although a cofactor is a non-protein chemical compound, cofactors are tied to a protein and is necessary for proteins to perform its biological functions. These types of proteins are almost always a kind of enzyme and cofactors can be thought as of â€Å"helpers† in performing its transformation. Vitamins or derivatives of vitamins make up an organic cofactor. 7. Chemosynthesis is the process by which organisms generate their own energy through chemical reaction rather than sunlight. This process converts carbon substances and nutrients into organic form (hydrocarbon) by oxidation as an energy source. 8. In the process called Glycolysis, requires two ATP’s to break down glucose into phosphoglyceraldehyde (2 PGAL). In the 2nd stage of glycolysis, the 2 PGAL’s are then broken into 2 pyruvates. This stage produces 4 ATP’s and 2 NADH’s. The net ATP production is 2 ATP’s as in the same case with the Krebs Cycle. 9. Stages in Photosynthesis The process of photosynthesis starts with the accumulation of substances needed by the process. These substances are carbon dioxide (CO2), water (H2O) and, of course, sunlight to be processed in the leaf’s chloroplasts. Sunlight then is converted into an energy form called ATP and NADPH. The sunlight absorbed through the stomata follows as certain chain of processing and results in the production of ATP, NADPH and oxygen. This process is called light reaction. Utilizing the ATP and NADPH, carbon dioxide is then converted into sugar. The resulting sugar is then broken down into two molecules called glucose and fructose, molecules that make up sucrose and sugar. The process is called dark reaction. 10. Assuming Photosynthesis I and Photosynthesis II refers to Light Reaction and Dark reactions: During light reactions electrons react as light strikes the chlorophyll. This results to the formation of ATP and NADPH. Also, water undergoes chemical reaction splitting oxygen and hydrogen. Carbon dioxide is accumulated from the atmosphere, hydrogen is added producing carbohydrates. This process is called carbon fixation. In the case of dark reactions, carbon dioxide is accumulated by a 5-C chemical called ribulose biphosphate (RuBP). Six molecules of carbon dioxide go in the Calvin Cycle, creating a glucose molecule. TP and NADPH created is used to attach phosphates into the PGA. Residual PGAL molecules are converted to reform 6 molecules of RuBP repeating the cycle again. REFERENCES Enger, E. D. , Ross, F.

Composite Materials In Automotive Brake Disc

Composite Materials In Automotive Brake Disc Abstract The aim of this paper is to explore the uses of ceramic matrix composites (CMCs) in the automotive industry, their advantages over current grey cast iron discs, their manufacturing processes and potential commercial applications. Cast iron brake discs consume much fuel due to its high specific gravity. As a result, a better and perhaps cheaper alternative is needed to fulfil the needs of high end automotive industries and even mid range consumer vehicles. INTRODUCTION Reducing green house gases and fuel consumption is a common goal for automotive industries and of paramount importance. Auto industries have dramatically increased the use of aluminium in light vehicles in order to reduce weight and help improve efficiency. Aluminium alloy based metal matrix composites (MMCs) with ceramic particulate reinforcement have shown great promise for such applications [1,2]. These materials having a lower density and higher thermal conductivity as compared to the conventionally used gray cast irons are expected to result in weight reduction of up to 50 60 % in brake systems [3]. Under severe service conditions like higher speed, higher load etc, these advanced materials have the potential to with stand these conditions. Basic mechanism of mechanical properties The high fracture toughness or crack resistance mentioned above is a result of the following mechanism: under load the ceramic matrix cracks, like any ceramic material, at an elongation of about 0.05%. In CMCs the embedded fibres bridge these cracks. This mechanism works only when the matrix can slide along the fibres, which means that there must be a weak bond between the fibres and matrix. A strong bond would require a very high elongation capability of the fibre bridging the crack, and would result in a brittle fracture, as with conventional ceramics. Thermal and electrical properties The thermal and electrical properties of the composite are a result of its constituents, namely fibers, matrix and pores as well as their composition. The orientation of the fibers yields anisotropic data. Oxide CMCs are very good  electrical insulators, and because of their high porosity their  thermal insulation  is much better than that of conventional oxide ceramics. The use of carbon fibers increases the  electrical conductivity, provided the fibers contact each other and the voltage source. Silicon carbide matrix is a good thermal conductor. Electrically, it is a  semiconductor, and its  resistance  therefore decreases with increasing temperature. Compared to (poly)crystalline SiC, the amorphous SiC fibers are relatively poor conductors of heat and electricity. CMC Brake Discs Disc brakes  are typically made out of grey cast iron. This material is has high tensile strength and can withstand a high temperature before failing. In high performance vehicles the amount of heat generated by friction when braking can be too great so the brakes fail or must be changed often. The failure is due to thermally induced fractures. Also these brakes can be heavy and susceptible to corrosion, which cause failure. Other composites have been tested such as Metal Matrix Composite, and Carbon Carbon Composites. The challenges with these materials are the ability to dissipate heat caused by friction isnt optimal at high enough temperatures. A typical grey cast iron disc brake can withstand a surface heat of 400 C before failure occurs. Type C/C-SiC is a Carbon fiber phase added to a Silicon Carbide matrix. The resulting material has increased strength with a lower density and high tribological characteristics. The most predominant feature is its ability to withstand high temperatures without failure. Due to its low coefficient of thermal expansion and high thermal conductivity, this CMC can retain its strength at high temperature. This CMC was manufactured as a disc brake with 2D reinforced discontinuous fibers. The fibers are placed perpendicular to the surface of friction to maximize Thermal conductivity. The result is a disc brake that can withstand surfaces temperatures of 1000 C with minimal wear. Problems There are multiple reasons for CMC disk brakes not being implemented among regular cars. Firstly, there is a low demand for high performance brakes due to the brakes themselves being rather expensive. As CMCs gain popularity, the cost of the raw material is expected to reduce, regardless of it being slightly expensive. Since regular cars arent used at high speeds, the amount of heat generated with low friction is small. As such, the Carbon Silicon Carbide brakes become inefficient and much weaker particularly in colder conditions. Thermal expansion of the composite and ceramic matrix results in this weakness. Cracking can occur on the surface of the brakes as the material expands at different rates under different temperatures. ADVANTAGES The integration of long multi-strand fibres has drastically increased the crack resistance,  elongation  and  thermal shock  resistance, and resulted in several new applications. As a result this has overcome the common problems associated with the conventional technical ceramics like alumina, silicon carbide, aluminium nitride, silicon nitride, or zirconia. Elongation  to rupture up to 1% Strongly increased  fracture toughness Extreme  thermal shock  resistance Improved dynamical load capability Anisotropic  properties following the orientation of fibers In comparison to the conventional grey cast iron brake disk the carbon-ceramic brake disk Weighed round 50 per cent less reducing the unsprung mass by almost 20 kilograms Improved brake response and fading data High thermal stableness No hot judder Excellent pedal feel Improved steering behavior High abrasion resistance and this longer life time and the advantage of avoiding almost completely brake dust The table below shows the properties of grey cast iron and its advanced alternatives (SGL Group n.d.)

They are: Matrix deposition from a gas phase Matrix forming via pyrolysis of C- and Si-containing polymers Matrix forming via chemical reaction Matrix forming via sintering Matrix formed via electrophoresis Matrix deposition from a gas phase involves a process known as chemical vapour deposition where in the presence of a fibre perform, the deposition takes place between the fibres and their individual filaments and thus called chemical vapour infiltration. Pyrolysis (Pyrolysis  is a  thermo chemical  decomposition  of  organic material  at elevated temperatures without the participation of  oxygen) of C- and Si-containing polymers involves hydrocarbon  polymers to shrink during  pyrolysis, and upon  out gassing  form carbon with an amorphous, glass-like structure, which by additional heat treatment can be changed to a more  graphite-like structure. Matrix formation via chemical reaction works by one material being located between the fibres that react with a second material to form the ceramic matrix. Sintering is used to manufacture oxide fibre/oxide matrix CMC materials. Special  precursor  liquids are used to infiltrate the pre-form of oxide fibres. In the  electrophoresis  process, electrically charged particles are dispersed in a special liquid are transported through an  electric field  into the preform, which has the opposite electrical charge polarity. Application in Brake Discs Carbon/carbon  (C/C) materials have found their way into the  disk brakes  of  racing cars  and  airplanes, and C/SiC brake disks manufactured by the LSI process were qualified and are commercially available for  luxury vehicles. The advantages of these C/SiC disks are: Very little wear, resulting in lifetime use for a car with a normal driving load of 300,000  km, is forecast by manufacturers. No  fading  is experienced, even under high load. No surface  humidity  effect on the friction coefficient shows up, as in C/C brake disks. The corrosion resistance, for example to the road salt, is much better than for metal disks. The disk mass is only 40% of a metal disk. This translates into less unsprung and rotating mass. The weight reduction improves shock absorber response, road-holding comfort, agility, fuel economy, and thus driving comfort. The SiC-matrix of LSI has a very low porosity, which protects the carbon fibers quite well. Brake disks do not experience temperatures above 500  °C for more than a few hours in their lifetime. Oxidation is therefore not a problem in this application. The reduction of manufacturing costs will decide the success of this application for middle-class cars.

Light in August by William Faulkner Essay -- Light August william Faul

Light in August by William Faulkner Light in August, a novel written by the well-known author, William Faulkner, can definitely be interpreted in many ways. However, one fairly obvious prospective is through a religious standpoint. It is difficult, nearly impossible, to construe Light in August without noting the Christian parallels. Faulkner gives us proof that a Christian symbolic interpretation is valid. Certain facts of these parallels are inescapable and there are many guideposts to this idea. For instance, there is Joe Christmas, one of the main characters in the novel. His initials are J.C., which can be an acronym for the name Jesus Christ. There is the fact of his uncertain paternity and his appearance at the orphanage on Christmas day, as well. Joe is approximately thirty-three years of age at his lynching; This event is prepared for throughout Light in August by Faulkner’s constant use of the word crucifixion. Also, there are many more convincing Christian symbolisms that seem to have lead readers to believe that William Faulkner arranged his events and directed his themes to parallel the twenty-one chapters of the St. John Gospel. These religious symbols, however, stray from the text of Light in August and seek to unify the novel through biblical allusions alone. They attempt to answer the questions of how Light in August functions as a work of literature by avoiding the novel itself. Because of this, they each fall short of being an exact interpretation of the novel. Still, the Christian parallels cannot be ignored and must function for some firm purpose in this novel. If Light in August has enough surfaces corresponding to warrant the claim of a direct parallel in both theme and action to the Gospel of John, then where is the crucifix, the most important symbol of Christianity? This significant tool should be in a book with such religious relevance. The important symbol was not left out, however; they were only distorted to a degree. Faulkner may have been giving a clue to the way in which he distorted the crucifix. For example, wood imagery is relevant in this case. There are several wood mills: Doane’s Mill, and then the planing mill in Jefferson. Lena asks Byron Bunch, â€Å"Is there another planing mill?† Byron replies, â€Å"No, ma’am. There are some sawmills, a right smart of them, though†. Faulkner may have been alerting his audie... ...not been a part of Christmas’ â€Å"wooden world†, now rides with a furniture repairman. Typically, Lena’s narration does not call attention to poles or posts of any kind. It is only after Christmas is dead that Lena notices the cross-like images. This would seem to suggest not only that she is perhaps a Virgin Mary figure carrying a Christ figure inside her, but also that she herself is the resurrect â€Å"life† after Christ’s (Christmas’) crucifixion. It seems highly possible in a novel that distorts the Crucifix that the process of Christ’s death and resurrection could also be distorted. Ironically, however, Lena exists at the same time with Christmas, but never meets him because within the context of the New Testament, resurrection comes only after death. In turn, Lena and Christmas never meet because it would be illogical for the Virgin Mary figure to meet her baby while she is carrying her baby. All of these characters’ narrations, which can appear incoherent, are, connected through the distorted image of the wooden cross. The posts and other symbols link Christmas and the Testaments together. Light in August functions as a fluid novel though structured distortion of the Gospels.

Obsessive Compulsive Disorders, Obsessive Compulsive Spectrum Disorders, and the P.A.N.D.A.S. Conne :: Biology Essays Research Papers

Obsessive Compulsive Disorders, Obsessive Compulsive Spectrum Disorders, and the P.A.N.D.A.S. Connection As someone who's been plagued by an Obsessive Compulsive Spectrum Disorder since childhood, I can say it seems hopeless at times. For so long a sufferer feels that what they have isn't a legitimate ailment and that he is alone in his battle. Thankfully, in recent years, more and more research is being done on Obsessive Compulsive Disorders, and more answers are being found. Obsessive Compulsive Disorders are the fourth most common psychiatric diagnosis. Sometimes the onset of symptoms is sudden, but more often than not it is a gradual progression. Precipitating events that could spur the onset of an Obsessive Compulsive Disorder can include emotional stress (domestic or job-related), increased levels of responsibility, health problems, and bereavement. According to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, "the essential features of an Obsessive Compulsive Disorder are recurrent obsession or compulsions that are severe enough to be time consuming (i.e.: they take more than an hour per day) or cause marked distress or significant impairment. At some point during the course of the disorder, the person has recognized the obsessions or compulsions are excessive or unreasonable. It's important to note that this is difficult concerning children because children tend to not realize that their compulsions are excessive or unreaso nable while adults do ((1) .). People develop compulsions by trying to ignore thoughts or impulses, or by trying to neutralize them with other thoughts or actions. Compulsions are mental acts, and include repeating words, ordering things, hand washing, and various other motions. The goal of these compulsions is to prevent or reduce anxiety. Because Selective Serotonin Reuptake Inhibitors (SSRI's) such as Prozac, Luvox, Zoloft, and Paxil are effective in controlling Obsessive Compulsive Disorders, it's believed that serotonin regulation is a part of the cause of OCD. Serotonin is a very important chemical messenger in the brain, and plays a role in a person's mood, aggression, impulse control, sleep, appetite, body temperature, and pain. Brain imaging studies have depicted various abnormalities in parts of the brains of Obsessive Compulsive Disorder sufferers. These parts include the caudate nucleus, the basil ganglia, the thalamus, orbital cortex, and cingulated gyrus. Disorders that have the obsessive compulsive symptoms of intrusive, repetitive behaviors are often called OC Spectrum Disorders. Amongst these include Trichotillomania, Monosyruptomatic Hypochondriasis, Body Dismorphic Disorder, and some eating disorders.

Online Recruitment

According to BusineeDictionary. com, â€Å"Human Resource Management includes activities such as human resources planning, recruitment, selection, orientation, training, appraisal, motivation and remuneration. It aims at developing people through work. † In human resource management, recruitment is one of the most important processes in an organisation. According to BusinessDictionary. com, â€Å"recruitment is a course of action of discovering and employing best eligible applicant, whether external or internal organisation, for a job position in a most suitable and cost effective way. There are different types of job recruitment, such as online recruitment and advertisement recruitment. In the 21st century, many of the organisations using online recruitment to search the best candidate for company, as the internet have transformed job hunting and recruitment. There are few types of online recruitment. One of the methods is professional websites. Example of professional websi te is www. shrm. org, where some candidates who are searching for human resources job go into that site. They have specific professions, skills and not general in nature. The second type is employer website. It can be developed by different employers or can be company own website. One example is www. directemployers. com, which is the first supportive, company owned online recruitment set up by Direct Employers Association. The last type is job board. Job seekers become aware of the vacancies where the recruiters post jobs and search for candidates. Example of job board is www. jobstreet. com. (Gosh, nd) In fact, there are still many other methods of online recruitment. Online recruitment has advantages and disadvantages in helping organisation for recruitment and selection. It has made more efficient on the employment process for every large and small organisation. For those companies who are still using paper applications have practised to use internet for important sections of the hiring process. The first benefit would be the reduce time for hiring. Online recruitment, is also called e-recruitment has enable a manager to have an immediate real-time communication and for everyday and every hour in job search activity. For example, a manager can post a vacancy in a very short time on a career site such as jobstreet. com without imitation. He or she can receive resumes in response immediately. In online job advertisement, the posting normally stays in available status for as long as one month and keeps on to receive candidates’ resumes as job seekers come across it. As compared with the traditional practises, job advertisement in newspaper or journal may take about one week or later but not only for one day. Therefore, employer has to wait till t he end of month to receive the responses by applicants, especially for those who need immediate vacancy and special areas industry. Bayt. com, 2009) According to Bayt. com, hiring in e-recruitment gives 70% faster than traditional recruitment practises, and the cycle of recruiting is speeded up at every process of posting, which is to receive applicant’s resumes and filter the information and call for interview. The second benefit of e-recruitment is cost effective. We need money to advertise the job vacancy in newspaper or journal, and this is not cheap for the advertisement. While the online posting is much cheaper as compared with traditional practises. According to bayt. com, the company post online to a job site such as www. bayt. com would be charged only USD250, which would be more cost-saving than the cost of job advertisement in newspaper or journal publication or the 30% of annual incomes that many personnel managers charge. Bayt. com shows a study that the costs of posting vacancy and searching for candidates on job vacancies can be up to 90% lower than the costs of adapting traditional search agencies and advertising practises. (Bayt. com, 2009) Third benefit is wider reach for manager. The information of traditional practises are normally restricted by industry, geography, career lever or other limitations while the e-recruitment can have recent and active talent databases that cover all industries, regions, and career levels. The company spent much to make sure the databases are varied, regular updated, relevant and best quality as they need to keep advertising in newspaper for changing, updating information. However, e-recruitment teams can ensure that the portals are always easily viewed by relevant applicants and are visited by the target job seekers which can easily reach to the manager. Bayt. com, 2009) Next benefit would be the wider reach for applicants. The candidates gain benefits from the wider span through internet job sites. With the click of a mouse, they are able to access different types of jobs in different companies, locations and even salaries. They can reach the company faster as they are easily contacted for interview opportunities by just send ing their resumes online. (Bayt. com, 2009) E-recruitment offers some screening or filtering tools which enable recruiters to immediately work on the right applicant using many categories on a site such as jobstreet. om, which including locations of residence, qualifications, education backgrounds, skills and past experience and employer. The process of e-recruiting and selecting good quality applicants is very efficient. This technology works by automated search engine which is set up to find the databases. For example employer can key in some of the requirements then the result would match with the candidates’ resumes. (Bayt. com. 2009) In online recruitment, company usually would set up a page like company profile or history for the candidates to view on it. Through this, employers can use this to create company brand and values to prospective job seekers. Therefore, applicants would make decision on applying that job as they have an idea about company they work for. (Bayt. com, 2009) Furthermore, through internet, recruiter can manage whole recruitment process from one mean, which enable recruiter to advertise vacancies, receive resumes, screen, contact applicants, track activities in internet. Therefore, the paper work is reduced. On the other side, the job seekers can also view their application progress at every step of recruitment process. This enhanced user experience for both job seekers and recruiters. In addition, both job seekers and recruiters can opt to maintain their confidentiality. For example, applicants can post their resumes online while keeping their names and current company’s name privately. Same thing to recruiters, they can choose to search databases without posting a job position if the vacancy nature is sensitive, and they can post a job vacancy while keeping their company name privately. Employers can also build up database, save high potential or attractive resumes from present applicants for future use. Bayt. com, 2009) Moreover, the manager has full control over the recruitment process through online recruitment, which enables direct contact with candidates which does not need a middle person to do the selection, filtering, and assessment. (Bayt. com, 2009) This is because recruiter can choose the best candidate through their details in resume and match with the position, which does not n eed so much of red tape. E-recruitment has brought so many benefits to organisations, as well as job seekers. Apart from its benefit, e-recruitment has quite a few drawbacks to the organisations. First of all, e-recruitment benefits for only applicants who knew internet knowledge. The process is limited to those computer savvy applicants. For those who know the use of internet, they have no problem to search different job websites, do screening, keywords, updating information. Therefore, it brings no benefit for those who do not know to use online job site. (Ghosh, nd) Besides that, company has to be very particular on legal consequences because it may lead to discrimination charge if the company did not aware of word used when posting the advertisement online. There is one example for Disney world, which was sued for screening applicants’ resumes by using the keywords preferred for Whites. (Ghosh, nd) As online recruitment became a trend, more and more applicants joined and apply for vacancy. The vast pool of candidates does benefits recruiters but also lead disadvantage to them. This is because they have to sit down and do a lot of deep scanning database. They might not view all the candidates which may miss out some of the best potential candidates as they might randomly choose candidates. As a result, applicants face more competition. Ghosh, nd) Furthermore, organisations face some non-serious candidates. Quite a number of candidates post their resumes just to know their employment value. Recruiters could not check whether the candidates are serious in applying job or not. When call for interview, recruiters just realised that candidates are not serious and not interested to join their company. By that time, the recruiters have r ejected some serious applicants. (Gosh, nd) The last drawback is disclosure of information. Candidate’s resumes and organisation profile are available to public. Some candidates who are still working do not want their present employer to know that they are looking for a change. Some of candidates’ particulars such as address, phone number has brought to many security problems. In addition, organisations do not want their competitors know their current situation. (Ghosh, nd) To make e-recruitment more effective, there are some criteria. Firstly we must benefit the selection procedure. Company should consider about different factors to make the procedure effective. Company should analyse and compare the costs and its risks by using return on investment (ROI). It helps to estimate the return and evaluate the benefits to company. Company should have change management, is to adapt market changes by making policy proactive and flexible. Company should provide guidelines in the policy. As the whole e-recruitment process depends on the availability of candidates in the market, company should consider market labour rate and unemployment rate. Recruiter should not spend too much of time to do screening, choosing candidates because this rates will decide whether to be lenient or stringent. Ghosh, nd) Moreover, recruiter should consider the impact of providing compensation information. He or she should follow legal norms when disclose information such as salary, wage and benefit. Candidates should not be given chances for negotiation. Besides, competitors would know the compensation rate of company. When screening resume, recruiter must take precautions. He or she must avoid using key words that discriminate race, religion, and gender. For example, ‘recent’ university graduates only in an ad are not preferable. Besides, recruiter should keep updating so that the candidates know the results and changes, otherwise it will not serve any purpose. (Ghosh, nd) Come to the modern impacts of e-recruitment, one of these is speedy communication. Management and staff can communicate with each other though the blogs. So, blogs, vodcasts, podcasts can be added as a tool in e-recruitment. Vodcasts are video podcasts while podcasts are digital media files services. As a result, recruiters cannot blame of being one way communication such as faxes and mails. Secondly, candidates today can choose the company which is not only look at the financial state but culture. In past experience, employers had privilege to be selective in recruitment process, especially in screening candidates’ resumes which were not fair to candidates. Therefore, image will not influence candidates to apply for company. Next, the number of popularity of search engine ads has increased, which resulting printed ads are phasing out, as pay-per-click is very attractive and convenient. Finally, job board is holding RRS feed, one of it is Google. For those who do not have any job site, Google offers them to post the jobs on Google Base. This is a group of web feed formats to publish updated works regularly, such as news headline, blog entries in standard format. (Ghosh, nd) In conclusion, traditional practises should not be replaced by online recruitment. It should be made as an enhancement. Online recruitment can be included by traditional practises and recruitment process will be speed up, globalise due to e-recruitment. We should make it as supplement, because both traditional and online are useful. When only three vacancies and three candidates available in organisations do not have much choice, hence companies prefer to broaden their search and attract a lot of applications. However, when company received two thousands applications for three vacancies, recruiters are not possible to do in depth screening process. While internal search is effective for a method such as campus interview, but without internet, interaction with candidates becomes time consuming when receiving application in hand. Of course, there are other concerns which companies need take into account, example like managing staff expectations. Recruiter can receive all applications electronically, even overnight. Overall, online systems offer major advantages in terms of improved efficiency, cost saving, and recruiter and candidate satisfaction. References: †¢ BusinessDictionary. com.

It aims at developing people through work. † In human resource management, recruitment is one of the most important processes in an organisation. According to BusinessDictionary. com, â€Å"recruitment is a course of action of discovering and employing best eligible applicant, whether external or internal organisation, for a job position in a most suitable and cost effective way. There are different types of job recruitment, such as online recruitment and advertisement recruitment. In the 21st century, many of the organisations using online recruitment to search the best candidate for company, as the internet have transformed job hunting and recruitment. There are few types of online recruitment. One of the methods is professional websites. Example of professional websi te is www. shrm. org, where some candidates who are searching for human resources job go into that site. They have specific professions, skills and not general in nature. The second type is employer website. It can be developed by different employers or can be company own website. One example is www. directemployers. com, which is the first supportive, company owned online recruitment set up by Direct Employers Association. The last type is job board. Job seekers become aware of the vacancies where the recruiters post jobs and search for candidates. Example of job board is www. jobstreet. com. (Gosh, nd) In fact, there are still many other methods of online recruitment. Online recruitment has advantages and disadvantages in helping organisation for recruitment and selection. It has made more efficient on the employment process for every large and small organisation. For those companies who are still using paper applications have practised to use internet for important sections of the hiring process. The first benefit would be the reduce time for hiring. Online recruitment, is also called e-recruitment has enable a manager to have an immediate real-time communication and for everyday and every hour in job search activity. For example, a manager can post a vacancy in a very short time on a career site such as jobstreet. com without imitation. He or she can receive resumes in response immediately. In online job advertisement, the posting normally stays in available status for as long as one month and keeps on to receive candidates’ resumes as job seekers come across it. As compared with the traditional practises, job advertisement in newspaper or journal may take about one week or later but not only for one day. Therefore, employer has to wait till t he end of month to receive the responses by applicants, especially for those who need immediate vacancy and special areas industry. Bayt. com, 2009) According to Bayt. com, hiring in e-recruitment gives 70% faster than traditional recruitment practises, and the cycle of recruiting is speeded up at every process of posting, which is to receive applicant’s resumes and filter the information and call for interview. The second benefit of e-recruitment is cost effective. We need money to advertise the job vacancy in newspaper or journal, and this is not cheap for the advertisement. While the online posting is much cheaper as compared with traditional practises. According to bayt. com, the company post online to a job site such as www. bayt. com would be charged only USD250, which would be more cost-saving than the cost of job advertisement in newspaper or journal publication or the 30% of annual incomes that many personnel managers charge. Bayt. com shows a study that the costs of posting vacancy and searching for candidates on job vacancies can be up to 90% lower than the costs of adapting traditional search agencies and advertising practises. (Bayt. com, 2009) Third benefit is wider reach for manager. The information of traditional practises are normally restricted by industry, geography, career lever or other limitations while the e-recruitment can have recent and active talent databases that cover all industries, regions, and career levels. The company spent much to make sure the databases are varied, regular updated, relevant and best quality as they need to keep advertising in newspaper for changing, updating information.
