Szalma (2014) points out that this assumption is faulty because automated machine technology can lead to human boredom, which can negatively impact stress levels and increase risk factors related to performance. According to the research study, motivation is comprised of three aspects -- goals, energy to pursue those goals, and the ability to persist against obstacles (Szalma, 2014, p. 1454). These variables can help to explain human behavior outcomes with regard to how humans respond to their environment -- and technology being part of the environment thus becomes a principal player in that outcome. Thus, the theory's usage is justified by the idea that an interface is meant to support an individual in attaining a goal as well as in the construction of meaning for the activity within the given context (Szalma, 2014, p. 1455).
The central concept utilized in the study is the self-determination theory of motivation and its application to human factors/ergonomics. The concept introduces the notion that technology is a factor in the way that humans behave because it is part of the environment. Motivation is the main concept that is discussed at length in the article. How boredom, fatigue and stress play a role in motivation is described (Szalma, 2014, 1455). Technology that is used for a goal-oriented purpose has an impact on individuals' level of boredom, stress and fatigue. Usability models, moreover, can be utilized to help describe the "motivational structures or processes underlying user intentions and behavior" (Szalma, 2014, p. 1456). The central concept is clearly defined and the reason that it is used as the focus of the article is made explicit and referenced thoroughly throughout the article. By assessing the issues of reducing risks within the workplace environment, such as fatigue, boredom and stress, the model can mitigate these factors and reduce their impact on performance levels. This assertion does not come by way of a formal hypothetical but it could be argued that it acts as one, as it is the main theory put forward in the article.
However, there is no specific, formal hypothesis or null hypothesis made for the study. No quantitative measurements are taken. Instead a model of motivation theory applied to human factors/ergonomics is developed and the…
The literature review was finally released in a document called "Scientific Support Documentation for the Revised 1991 NIOSH Lifting Equation: Technical Contract Reports, May 8, 1991." (Applications Manual for the Revised NIOSH Lifting Equation) This is an update and contains information on the physiological, biomechanical, psychophysical, and epidemiological aspects of manual lifting. This led to the recommendation by the ad hoc committee of the criteria for defining the lifting
Safety Ergonomics in the Workplace The yearly worldwide trouble of one hundred million occupational injuries and diseases imposes upon national productivities, business efficiencies and employees' health and well-being, in Australia. Manual handling is the biggest supplier to non-deadly injury and disease in the workplace, normally accounting for about a third of all national injuries. Interventional approaches that have centered on choosing or adapting the employee have been unsuccessful in dropping injury danger.
Professional Journal Field Ergonomics Arti The article critiqued in this document is entitled "Workplace economics." It was authored by representatives from the American Chiropractic Association -- although a specific author is not identified. This article serves as an overview to the field of ergonomics as it affects the workplace. The author approaches the topic from a decidedly broad perspective. There are a number of generalizations that are made in this
Fibromyalgia syndrome (FMS) is a complex medical condition that affects about 5 million American people. The condition is characterized by "chronic widespread pain, fatigue, sleep disturbance, stiffness, impaired memory and concentration, anxiety and depression." (Facts of Life, 2001). Sleep disturbance and an increased sensitivity to pain follow a cyclic pattern in individuals having FMS, the result of which is a positive feedback loop. (Etiology of Fibromyalgia, 2003). Typically, fibromyalgia affects women,
ergonomics in the practice of dentistry, focusing on tendinitis. Improper ergonomics exacerbates a tendency to acquire tendinitis and other musculoskeletal concerns. In particular, the lack of hand and wrist supports during dental work is related to the presence of tendinitis in those joint areas. This research used thermo graphical methods to measure the difference between a dentist who experiences tendinitis and one who does not. Thermography is a common
designing tools to be used by consumers or workers, it is widely assumed that the product must be both visually appealing as well as ergonomically functional. In certain workplace applications, if specific tools are not used, injuries may occur. Previous research on hand tools required in factory work, such as gripping tongs, have found that the product may be ignored if it is perceived to be cumbersome to use.
