Another one of our seminar participants just passed his defense with flying colors. A big congratulation to who recently received his PhD from the University of Tennessee, Knoxville. His field of study is Consumer Behavior and his dissertation looked at interaction with mobile technology producers.
Most previous stress theories were developed to describe reactions to inevitable acute stress in situations threatening biological survival (Cannon 1935; Selye 1936). However, the Demand/Control model was developed for work environments where stressors are chronic, not initially life threatening, and are the product of sophisticated human organizational decision making. Here, the controllability of the stressor is very important, and becomes more important as we develop ever more complex and integrated social organizations, with ever more complex limitations on individual behaviour. The Demand/Control model (Karasek 1976; Karasek 1979; Karasek and Theorell 1990), which is discussed below, is based on psychosocial characteristics of work: the psychological demands of work and a combined measure of task control and skill use (decision latitude). The model predicts, first, stress-related illness risk, and, secondly, active/passive behavioural correlates of jobs. It has mainly been used in epidemiological studies of chronic disease, such as coronary heart disease.

In contrast with climate, culture is less frequently studied as a contributing factor to employee well-being or occupational risk. The absence of such research is due both to the relatively recent emergence of culture as a concept in organizational studies and to ideological debates regarding the nature of culture, its measurement (quantitative versus qualitative), and the appropriateness of the concept for cross-sectional study (Rousseau 1990). According to quantitative culture research focusing on behavioural norms and values, team-oriented norms are associated with higher member satisfaction and lower strain than are control- or bureaucratically -oriented norms (Rousseau 1989). Furthermore, the extent to which the workers values are consistent with those of the organization affects stress and satisfaction (OReilly and Chatman 1991). Weak cultures and cultures fragmented by role conflict and member disagreement are found to provoke stress reactions and crises in professional identities (Meyerson 1990). The fragmentation or breakdown of organizational cultures due to economic or political upheavals affects the well-being of members psychologically and physically, particular in the wake of downsizings, plant closings and other effects of concurrent organizational restructurings (Hirsch 1987). The appropriateness of particular cultural forms (e.g., hierarchic or militaristic) for modern society has been challenged by several culture studies (e.g., Hirschhorn 1984; Rousseau 1989) concerned with the stress and health-related outcomes of operators (e.g., nuclear power technicians and air traffic controllers) and subsequent risks for the general public.

Because he is more irritable, perhaps his wife criticizes him for accepting his new assignment and bringing his problems home. As a result of all these factors, the worker reacts to the feelings of distress, perhaps with an increase in alcohol consumption or by experiencing undesirable physiological reactions, such as the elevation in blood pressure. The troubles at work and in the family continue, and his reactions, originally of a transient type, become sustained. Eventually, he may enter a chronic anxiety state or develop alcoholism or chronic hypertensive disease. These problems, in turn, increase his difficulties at work and with his family, and may also increase his physiological vulnerability. A vicious cycle may set in which may end in a stroke, a workplace accident or even suicide. This example illustrates the environmental programming involved in the way a worker reacts behaviourally, physiologically and socially, leading to increased vulnerability, impaired health and even death.

Biomedical recording techniques permit the monitoring of bodily responses at the workplace without interfering with the workers activities. Using such ambulatory-monitoring techniques, one can find out what makes the blood pressure rise, the heart beat faster, the muscles tense up. These are important pieces of information which, together with stress-hormone assays, have helped in identifying both aversive and protective factors related to job content and work organization. Thus, when searching the work environment for harmful and protective factors, one can use the people themselves as measuring rods. This is one way in which the study of human stress and coping may contribute to intervention and prevention at the workplace (Frankenhaeuser et al. 1989; Frankenhaeuser 1991).
