Recruitment and Selection Strategies - Essay Example It starts with the hunt for new employees and it continues till a pool of application is generated out of which new employees are selected. To develop a good strategy an organization an organization should always keep itself updated on the opening that are present in it , openings that may be required and positions that are potentially going to be vacant in the future. An organization should target the positions needed immediate fillings first, but it is best to predict the vacancies and plan for recruitment as this ensures that the quality of recruitment activities stays good. Requirements for a certain type of position should be fully understood for better recruitment. The performance level required, the experience needed by the potential employee should ne properly be established. The organization should identify that the vacant post can be best filled by external recruitment or internal recruitment. Some organizations feel that employee referrals are very effective forms of recruitment source (Lisa Guerin, 2007). Vacancies are mostly properly advertised. Human resources personnel involved in recruitment should have proper training and experience so that they can judge the skills and parameters required for the job and determine if they are present in the candidate or not. Evaluation methods of candidates should be described (Linda L. Neider, 2003). The most popular evaluation methods are written tests, interviews, psychometric tests (Carter, 2004) or a combination of these. Things that affect the recruitment process are the organizations objectives and policies, the government policies and labor laws, the source of recruitment traditionally used by an organization, the current needs of the organization and the costs affiliated with the recruitment (Rouse, 2007) The recruitment challenges faced by organizations are that the labor in some countries has aged and the pension costs are becoming high. In the modern day the organizations invite employees from all around the world (Hook, 2008), to generate a larger candidate pool the organizations use modern sources like outsourcing. Organizations outsource their recruitment activities to another organization which screens candidates initially according to organizational requirements given to it so that its employer organization can select employees from its screened candidate pool (Ian Beardwell, 2007). The advantage of this is that even if the company is not planned for a vacancy it can forward its need to the outsourcing organization and get a desired employee in lesser amount of time. It also creates competitive advantage by speeding up the process of recruitment; it helps the management to stay focused on other things rather then the generation of a candidate pool. These organizations usually negotiate salaries on the behalf of their employers to save time and resources of its employers. Poaching and raiding is also another way of acquiring talent, in this the organizations attract and employee a person who is already an

Biochemical Oxygen Demand Hypothesis Testing Essay

Biochemical Oxygen Demand Hypothesis Testing - Essay Example Rejection of the null hypothesis leads to the acceptance of the alternative hypothesis. The alternative hypothesis states that there is a difference between the procedures. It is denoted by H1. Assuming that the upstream BOD and downstream BOD are normally distributed, we test using significance level of 0.05 whether BOD increases at the downstream. The significance level of a statistical hypothesis test is a fixed probability of rejecting the null hypothesis H0 when it is in fact true. It is called a type I error and is set by the investigator in relation to the consequences of such an error. We want to make the significance level as small as possible in order to protect the null hypothesis and to prevent, as far as possible, the investigator from inadvertently making false claims. Test Statistic: It is the random variable X whose value is tested to arrive at a decision. The Central Limit Theorem states that for large sample sizes (n > 30) drawn randomly from a population, the distribution of the means of those samples will approximate normality, even when the data in the parent population are not distributed normally. A z statistic is usually used for large sample sizes (n > 30), but often large samples are not easy to obtain, in which case the t-distribution can be used. The population standard deviation s is estimated by the sample standard deviation,The observed t value is calculated from the sample used. Testing of means can be accomplished when the data are in the form of paired observations. We compute for the confidence interval of d - u in the situation with paired observations is based on the random variableWhere and are random variables representing the sample mean and standard deviations of the differences of the observations in the experimental un its. This two-sample problem is essentially reduced to a one-sample problem by using the computed difference d1, d2, d3 dn. Thus the hypothesis reduces to Ho: =do
