Critique of Selected Epidemiological Article - Research Paper Example The study reports a hypothesis that the visits that are undertaken for the older age in the cardiovascular study is related to main demographic, lifestyle, health and function participant traits and that the oldest age would have the poorest retention for in-person visits, particularly clinic visits. The hypothesis of the study is directional as it has taken a stand on the subject matter which is yet to be determined. However, it is a complex one since the measurement methods would not be easy in terms of tool applications. It also requires the application of more than one tool for its determination. It was tested using the face to face interviews, phone interviews, as well as personal visits. This was also done through sampling from Medicare eligibility lists, non-institutionalized, ambulatory men and women aged 65 and above. During the study, men and women of age 65 and older got enrolled including the 5201 at 4 US field centers. These formed a mean enrollment age of 73 years with a range of 65-100 forming 58%, 16 % being black. The first phase took place in 1989 to 1990 with the addition of 687 African-American participants in the year 1992 to 93. The participants were taken through an extensive baseline evaluation. This included the laboratory assessments, physical and cognitive functioning and medical history. All these components were repeated at the annual clinic visits through 1998 to 1999. The total population of the study of surviving participants throughout the time was, N=43,772. By the year 2005-06, the entire population was re-recruited in order to reevaluate physical and cognitive functioning and reassess functional status. In this case, the median age was 85 while the range was 77-102 of which 67% were women, and 17% were black (Strotmeyer, et al., 2010). The study in this case was quasi-experimental since it involved the determination of the

Team motivation - Case Study Example For any organisation to be productive, it needs to motivate its employees towards its goals so that it achieves its business objectives. Motivation for the employees can be internal or external. While external motivation is an incentive provided by another person, internal motivation is offered by the environment and achievement of the task. But just as the individuals are unique, motives are unique as well. They are individualistic, they evolve with the times and change and are hierarchical as well. What works for one person may not work for another person. Therefore finding the right motivating factor is a challenge by itself. It is a continuous process. The various theories have tried to analyse how exactly motivation works, and have added a lot of research and valuable knowledge that can applied to a current situation to arrive at a solution that best suits the current needs under the operational constraints. There is no universal theory that can be applied to all the situations and offer a universal solution. Fredrick Herzberg tried to understand the factors associated with job satisfaction which motivated or demotivated people to perform a task. These factors, called Motivators, if present caused Job satisfaction. Motivators usually included nature of task, responsibility, promotion, recognition awards and a sense of achievement. The absence of these motivators signalled lack of satisfaction according to Herzberg. He also found that another set of factors, when absent, caused Job Dissatisfaction. However the presence of these factors did not cause Job Satisfaction. The presence of these factors called Hygiene Factors meant that the people were not dissatisfied, but neither were they satisfied. Hygiene factors included company policies, supervision, low rewards, substandard working conditions and poor relationship in the workplace. "Turning past de-motivators within your organization into future motivators for employees and aligning them to the objectives of the company will ensure both succeed". (Source:
