Download file to see previous pages Objectives of Our Study and the Study Design The objective of the study was to found the effect of the various factors that contribute to the vision problems in totality by applying regression logistics and the study design was to include a proper sampling strategy, representation and analysis of the data to draw the logistic regression equations. This would give an idea what proportions of the various factors are related to the vision problems and the weightage that has to be attributed while interpreting the results. Methodology Collection Of Data The first thing for any study is the process of data collection and the method of sampling. Data is collected on the basis of sampling which can be randomized, or purposive with respect to the variable that has to be analyzed. Randomized data means each individual will have equal probability to be included in the sample. Purposive data is considered by some criteria fixed by the experimenter (effects of a drug on diabetic patients).Sampling makes sure that the results are based on non biased assumptions and simply random sampling reduces the chance of bias. So in this study we will fix inclusion criteria with a purposive sampling- that means people who use computers whether desktops and laptops will be included and the others in the population will not be included- thus our purposive sampling will narrow it to population of computer users. The exclusion criteria would be non computer users and having vision problems other than technology related. Data will be collected through a set of questionnaire method:- a. Vision severity score: Rate your vision problems on a scale of 1 to 10 b. Are you ergonomically satisfied with the workstation in which...
This essay approves that the quality of the antiglare screens also causes a problem as because the damaging effects of the uv radiations in the eye are quite dangerous and finally a proper ergonomic work station design is also important. These include provision of propr sitting posture, chair design and foot rest because the design might have been created for the general population as the whole but individual constraints can be present to use the same design dimensions and there should be place of flexibility. Thus one can see the detrimental effects of modern technology on vision problems are quite well recognized.
This paper makes a conclusion that if the study design can be made in this fashion we can get an idea as to how the vision problems are differing across different age groups and whether those results are significant or not. Then we can also see the factors responsible for causing the vision problems from one group to the another. Ultimately having done that we can find how each of the factors will be related to the vision score on a both independent basis and concerted basis by the regression equations and the correlation co-efficients. The overall study design planned and conducted will give us informations what are the steps based on design of workplace or computers, duration of computer usage time safe for eye and the anti-glare screens can be designed and addressed to minimize the effects of modern technology like computer usage on our eyesights. ...Download file to see next pages Read More

Research methodologies and personality

Personality Questions Personality is a concept that most people could recognize but the term still lacks a consistent definition. The general consensus appears to favor the identification of behaviors, beliefs, and attitudes as factors that can be observed as components of personality. Long-term consistency has also been discussed as a potential characteristic of personality (Ryckman, 2013), but it is often demonstrated that apparent personality does not always accurately predict behaviors or other related factors. This variability is due to the role of both biological and environmental factors in the manifestation of personality on a case to case basis. Genetic expressions, neurotransmitter systems, biological health, and psychol...

Organisations in the Engineering and Technology Environment: Singapore Airlines

Discovering the Tragic Hero: Ancient and Modern

...Discovering the Tragic Hero: Ancient and Modern The concept of the tragic hero was first brought forward in ancient Greek mythology through the writings of the philosopher Aristotle as he described the important individual characteristics the tragic hero must possess. Although Aristotle outlines three requisite character traits that the tragic hero should possess, he qualifies the definition of the tragic hero with a set of events that must also take place before the hero can be considered truly tragic. Once this process is understood, it is easy to see how the sudden downfall of a mighty man, such as Oedipus the King from the play by Sophocles for example, would be dramatic and shocking to a public dominated by strict social classes...
