Work stress and musculoskeletal disorder etiology: The relative roles of psychosocial and physical risk factors

The intense battles preceding the recent promulgation of OSHA's Ergonomics Program Standard serve as a case study demonstrating the growing understanding that MSD causation, development, and exacerbation are the result of the combined contribution of (and possibly interaction between) a wide range of biomechanical and psychosocial stressors. The best designed studies, those that adequately measure both biomechanical and psychosocial exposures, strongly support this hypothesis. Work stress is one of the results of this stressor combination and is part of the physiological pathway to MSDs and a wide range of other occupational diseases. Prevention efforts geared to a single or single class of exposure may be only partly effective, ineffective, or even counter productive. The most effective control strategies are rooted in on-going, participatory ergonomics programs, incorporating a joint labor/management ergonomic team; this blueprint for intervention necessarily addresses the roots of both physical and psychosocial work stress experienced by workers.     

Functional testing: Approaches and injury management integration

Functional Capacity Evaluations (FCEs) have become the standard for identifying an individual's physical abilities and/or limitations following injury or illness. While philosophies and approaches differ, the focus of most FCE systems is to identify the individual's maximum capabilities. This article will discuss the usefulness of the FCE information and how FCEs are impacted by multiple factors including APTA guidelines, machine based testing, therapist expertise, medical legal credibility and court testimony, IMEs and FCE, and return to work/return to function.     

Technology and managing people:

conclusion The Information Age has revolutionized the workplace. While it is possible to purchase or copy machines and technology, their very interchangeability means they fail to cre-ate a sustained competitive advantage for an organization (Barney, 1991). The research directions this paper offers are intended to develop firm knowledge that allows creation of inimitable human resources. Importantly, in the rush to embrace new information technologies, organizations must remember the fundamental principle that workers will invest in firm goals in the presence of shared values and a commitment by the firm to make their well-being a priority. We urge continued attention to fulfillment of the psy-chological contract, and to the "people issues" that frequently seem less critical than issues of hardware or technology.     

互补品天才

安德烈和爱德华当初是怎么想的？ 1900年，就在两兄弟刚刚接管家族设在克莱蒙一费朗市橡胶生意之后不久，他们决定为旅行者出版一本指导手册。在他们的《米其林指南》一书当中，作者提供了大量加油站、酒店、餐厅和观光景点的信息，并配有详尽的地图和旅行提示。该书第一版印刷了35000册，米其林公司免费将其发放给那些感兴趣的读者们。他们的这一做法后来被证明是一个极其天才的举动。     

Social Amplification of Wildfire Risk: The Role of Social Interactions and Information Sources

Wildfire is a persistent and growing threat across much of the western United States. Understanding how people living in fire‐prone areas perceive this threat is essential to the design of effective risk management policies. Drawing on the social amplification of risk framework, we develop a conceptual model of wildfire risk perceptions that incorporates the social processes that likely shape how individuals in fire‐prone areas come to understand this risk, highlighting the role of information sources and social interactions. We classify information sources as expert or nonexpert, and group social interactions according to two dimensions: formal versus informal, and generic versus fire‐specific. Using survey data from two Colorado counties, we empirically examine how information sources and social interactions relate to the perceived probability and perceived consequences of a wildfire. Our results suggest that social amplification processes play a role in shaping how individuals in this area perceive wildfire risk. A key finding is that both “vertical” (i.e., expert information sources and formal social interactions) and “horizontal” (i.e., nonexpert information and informal interactions) interactions are associated with perceived risk of experiencing a wildfire. We also find evidence of perceived “risk interdependency”—that is, homeowners’ perceptions of risk are higher when vegetation on neighboring properties is perceived to be dense. Incorporating social amplification processes into community‐based wildfire education programs and evaluating these programs’ effectiveness constitutes an area for future inquiry.     

Introduction: “There Is a Person Here”: An Interview with Judith Butler

In this interview, the coeditors, along with other contributors, ask Judith Butler a variety of questions regarding queer theory, gender identities, scientific and legal discourse, bodily abjection, race and class positioning, and political organizing. This range of subject matter suggests not only the breadth of Butler's work, but also its applicability to any number of people, whose relation to theory ranges from highly politicized to politically indifferent. The interview demonstrates the responsiveness of Butler's work to cultural translation and political action.     

Forecasting the Incidence of Cancer in Regional Victoria,Australia

Loddon Mallee Integrated Cancer Service plays a key role in planning the delivery of cancer services in the Loddon Mallee Region of Victoria, Australia. Forecasting the incidence of cancer is an important part of planning for these services. This article is written from an industry perspective. We describe the context of our work, review the literature on forecasting the incidence of cancer, discuss contemporary approaches, describe our experience with forecasting models, and list issues associated with applying these models. An extensive bibliography illustrates the world-wide interest in this forecasting problem. We hope that it is useful to researchers.     

Some sampling effects of pairwise correlated observations on likelihood ratio tests for the difference between two means

We study the effects of the inclusion of pairs of correlated observations in a sample on likelihood ratio tests for the difference in two means. In particular, we assess how the inclusion of correlated data pairs (e.g., such as data inadvertently collected from sib-pairs) affects the sample size requirements necessary for the implementation of a Likelihood Ratio (LR) test for the difference between two means. Our results suggest that correlated data pairs beneficially or adversely effect sample size requirements for an LR test to a degree functionally related to the mixture parameters dictating their relative frequencies in the larger sample on which the test will be performed, the strength of the correlation between the observations, and the size of imbalances in the sample with respect to the number of observations in each group. The relevance and implications of the results for genetic and epidemiologic research are discussed.     

THE PROCESS OF CHANGE IN COUPLES THERAPY: A QUALITATIVE INVESTIGATION

Open-ended interviews with 24 couples therapy clients regarding their experience of the process of change revealed shifts in clusters of affect, communication, and cognition. Six additional contextual preconditions for change were also identified. The change process within couples was uniformly reported to be gradual.
