Functions of the Human Body in Relation to Occupational Health and Safety in the Working Environment - Research Paper Example   Similar to any mechanical system, the body might be stable or unstable and is able to bear a restricted gamut of physical pressures. Pressures might be forced internally or externally and might be severe or chronic. A helpful beginning in the deliberation of mechanical loading of the body is to differentiate between postural stress and task-induced stress. In the opinion of Grieve and Pheasant, postural stress is the expression used to signify the mechanical load on the body due to its posture. Posture can be defined as the average directions of the parts of the body in the course of time. (iii) Task-stress is dependent on the mechanical endeavor required to carry out daily tasks. It is a fact that majority of the repetitive tasks need a combination of static and rhythmic muscle activity. In the case of manual work, postural stabilization of the hands and arms is important for performing all but the complete movements in a purposeful manner. (iv) This stabilization is given by th e muscles more up the kinetic chain, muscles which cross the elbow and shoulder joints and have their origins in the cervical spine and thoracic areas. (v) When the task demands are quite above normal, the muscles might experience pain providing stabilization or in the muscles and joints of the effectors, or in both. In a period of time, a medical condition might develop. (Bridger 4-5) Explain why the role of individual susceptibility should b... identifying adverse effects on health and how you would use this information when considering potential scope and impact of situations with adverse effects on health. It is important to consider individual susceptibility when identifying adverse effects on health for which a separate branch has emerged known as ergonomics. Physiological problems happen when too much work is demanded from the body, to work awkwardly or to work under adverse environmental conditions. Fatigue happens mostly from work. To remain stable, the worker must not be more than tired at the end of his working day. Therefore the rest given into the task must be sufficient without becoming too heavy and unfeasible. In case of ergonomics, they access physical work through measurement of oxygen that is inhaled, change of heart rate, but are generally tied down by just being capable to calibrate people under semi-natural conditions. Nevertheless, in an identical fashion, they are able to calculate recovery from exhaustion. This bears a direct association with rest allowances, for example, it has been verified that even though learners require more rest compared to qualified workers , they are prone to make themselves tired by not resting sufficiently during the initial portion of their work. A natural balance exists between work and rest periods every day in which the quality and quantity of work are at the highest.  Ã‚

Internet and Social networking Privacy - Essay Example The author of the essay "Internet and Social Networking Privacy" thinks that privacy concerns is one of the most troubling issues for users of social networking sites today, but this problem has been largely underresearched.

This, however, does not prevent most users from using the limitations on their profiles. Raising awareness among users about perceived dangers of excessive disclosure is one way to handle the situation. Some other ways should include enhancing the privacy policy of certain websites, legislative restrictions, etc. This is because studies show that users are so much willing to share that they may neglect the risks even being aware of dangers. Out of the studies discussed above, the first one seems most credible since it uses the largest sample of 4, 000 students. Besides, it has the strongest theoretical basis and a broader range of research.
