The contribution of supervisor behaviour to employee psychological well-being

Many employees affirm that supervisors affect employee well-being, and research has demonstrated associations between supervisor behaviour and employee psychological well-being. However, what hasn't been clear is the extent to which the association with supervisor behaviour compares with that of other variables known to affect well-being. This exploratory study addresses that issue. Our hypothesis was that supervisor behaviour can contribute to the prediction of psychiatric disturbance beyond the contribution of other influential variables. We created a new, questionnaire-based instrument to measure supervisor behaviour. We tested our hypothesis using stepwise regression with a convenience sample of 167 men and women working in a variety of organizations, occupations, and industries in the USA. Results supported our hypothesis: supervisor behaviour made a statistically significant contribution to the prediction of psychiatric disturbance beyond a step-one variate comprised of age, health practices, support from other people at work, support from home, stressful life events, and stressful work events. This provides additional evidence that supervisor behaviour can affect employee well-being and suggests that those seeking to create healthier workplaces should not neglect supervision. We believe that there is now ample justification for those concerned with psychosocial working conditions to consider supervisor behaviour as a potentially influential variable.

Furthermore, we believe that we have presented a new instrument for assessing supervisor behaviour that has the potential to be of value in future studies.     

Measuring work stressors: The role of frequency,duration, and demand

Abstract

In recent years a number of authors have suggested that progress towards a better understanding of the stressor-stress relationship can only be achieved by altering the way in which work stress is investigated. One strategy is to investigate what it is we are measuring when we assess work stressors. More particularly there is a need to use rating scales that measure demand associated with work roles rather than just imply it. Dimensions such as frequency, duration, and level of demand were measured in addition to the traditional method of simply asking individuals to indicate whether they agree/disagree that stressors are present at work. The results point to the incremental increase in variance explained when these additional facets are measured over and above the variance explained by traditional methods. This result confirms the ned to develop a better understanding of the concept of demand, the difference between chronic and acute stressors, and the interaction effects of the different facets.     

Expert Review on Poliovirus Immunity and Transmission

Successfully managing risks to achieve wild polioviruses (WPVs) eradication and address the complexities of oral poliovirus vaccine (OPV) cessation to stop all cases of paralytic poliomyelitis depends strongly on our collective understanding of poliovirus immunity and transmission. With increased shifting from OPV to inactivated poliovirus vaccine (IPV), numerous risk management choices motivate the need to understand the tradeoffs and uncertainties and to develop models to help inform decisions. The U.S. Centers for Disease Control and Prevention hosted a meeting of international experts in April 2010 to review the available literature relevant to poliovirus immunity and transmission. This expert review evaluates 66 OPV challenge studies and other evidence to support the development of quantitative models of poliovirus transmission and potential outbreaks. This review focuses on characterization of immunity as a function of exposure history in terms of susceptibility to excretion, duration of excretion, and concentration of excreted virus. We also discuss the evidence of waning of host immunity to poliovirus transmission, the relationship between the concentration of poliovirus excreted and infectiousness, the importance of different transmission routes, and the differences in transmissibility between OPV and WPV. We discuss the limitations of the available evidence for use in polio risk models, and conclude that despite the relatively large number of studies on immunity, very limited data exist to directly support quantification of model inputs related to transmission. Given the limitations in the evidence, we identify the need for expert input to derive quantitative model inputs from the existing data.     

Treatment for Juveniles Who Sexually Offend in a Southwestern State

A 25-item questionnaire was mailed to sex offender treatment providers from counties with 60 or more reported juvenile sex offenders in a Southwestern state to determine the most effective treatment for juvenile sex offenders. Results indicated that cognitive behavioral therapy was the most successful reported approach to treatment with an average success rate of 87%. The most commonly used approach was cognitive behavioral therapy with relapse prevention. The most common sexual offense was indecency with a child involving sexual contact, contrary to studies that found that in the Probation Commission data, aggravated sexual offense was the most common. These results have ramifications for state policies on treatment for juvenile sex offenders.     

Sensation Seeking and Impulsivity: Combined Associations with Risky Sexual Behavior in a Large Sample of Young Adults

Although prior studies have shown that sensation seeking and impulsive decision-making are related to sexual risk-taking, it is still unclear whether these personality traits operate independently or synergistically. The purpose of this study was to elucidate the joint contribution of these personality traits to HIV and sexually transmitted disease (STD) risk behaviors using data from a large sample of sexually active young adults (N = 2,386). Regression modeling indicated that both sensation seeking and impulsive decision-making were consistently associated with sexual risk behaviors across 11 risk-related outcomes. Results further indicated that sensation seeking and impulsive decision-making operated synergistically with respect to the outcome variables of sex acts using drugs, acts with a partner using alcohol, and acts with a partner using drugs. In contrast to this, sensation seeking and impulsive decision-making operated independently with respect to the other sexual risk outcomes. Theoretical implications, as well as implications for HIV/STD prevention among high sensation seekers and impulsive decision-makers, are discussed.     

European Regional Populations: Current Trends, Future Pathways, and Policy Options

Europe is currently experiencing an ageing population and slowing population growth of both the total and working-age populations. These trends are likely to continue. Even though population ageing will affect all European regions, different regions will be affected in different ways. Even under favorable conditions, 35–40?% of all NUTS2 regions will face a labor force decline. If economic conditions are poor, some regions may continue to grow, but 55–70?% of the regions will see a labor force decline by 10?% or more. In most regions of Eastern Europe, the labor force may decrease by more than 30?%. To keep regions prosperous (maintaining competitiveness) and to avoid worse inequality (maintaining cohesion), policy-makers must find ways to cope with these challenges through new fiscal and social policies, though policies directly affecting demographic and migratory trends may also be needed.     

Ethnic population projections for the UK, 2001–2051

This paper reports on projections of the United Kingdom’s ethnic group populations for 2001–2051. For the years 2001–2007 we estimate fertility rates, survival probabilities, internal migration probabilities and international migration flows for 16 ethnic groups and 355 UK areas. We make assumptions about future component rates, probabilities and flows and feed these into our projection model. This model is a cohort-component model specified for single years of age to 100+. To handle this large state space, we employed a bi-regional model. We implement four projections: (1) a benchmark projection that uses the component inputs for 2001; (2) a trend projection where assumptions beyond 2007 are adjusted to those in the UK 2008-based National Population Projections (NPP); (3) a projection that modifies the NPP assumptions and (4) a projection that uses a different emigration assumption. The projected UK population ranges between a low of 63 millions in 2051 under the first projection to a high of 79 million in the third projection. Under all projections ethnic composition continues to change: the White British, White Irish and Black Caribbean groups experience the slowest growth and lose population share; the Other White and Mixed groups to experience relative increases in share; South Asian groups grow strongly as do the Chinese and Other Ethnic groups. The ethnic minority share of the population increases from 13% (2001) to 25% in the trend projection but to only 20% under our modified emigration projection. However, what is certain is that the UK can look forward to be becoming a more diverse nation by mid-century.     

走向一种为了共同福祉的建设性后现代主义

与现代主义相比,建设性后现代主义更有助于实现生态文明以及人类社会的和谐发展.二者形成鲜明的对比:现代主义把主体自我视为意义和价值的唯一源泉,后现代主义则以群体为先;现代主义是以竞争和支配的模式为基础,后现代主义的核心价值观却是合作;现代主义认为社会为个人而存在,后现代主义者则关心每一个体的幸福;现代主义主张事物之间的机械性关联,后现代主义则强调一切生物间的有机联系;现代主义常常自我鼓吹,否弃传统,后现代主义却能够尊重传统智慧.
