Comparison of ergonomic risk assessment outputs from Rapid Upper Limb Assessment and the Strain Index for tasks in automotive assembly plants

This paper compares the ergonomic risk assessment of a task for the upper extremities as determined by Rapid Upper Extremity Assessment (RULA) and the Strain Index (SI). The ergonomic risk to the upper extremities of 244 automotive assembly plant tasks were evaluated using RULA and SI. The outcomes of each tool were compared for each task. Results from this study provide practical insight into the methods used in each tool. This study compared only the ergonomic risk outputs from each tool; it does not pursue the question of which tool best predicts injury. The kappa score was 0.11, indicating little agreement between the outputs of the two tools. This is supported by the lack of monotonicity with a gamma score of 0.1. These results indicate that the risk assessment outcome of these two ergonomic assessment tools for the upper extremities do not agree.     

The Effects of Information Overload on Software Project Risk Assessment*

Managers are responsible for providing effective information technology governance of the software development process. Ineffective governance leads to serious resource misallocations and negative consequences concerning Sarbanes‐Oxley compliance. In order for managers to make informed decisions about software development projects, they often need more information than is available through normal information channels, that is, they need an in‐depth review of the at‐risk project. Such in‐depth reviews, however, are costly. Hence, accurate identification of at‐risk projects for in‐depth review is critical to management's ability to govern. This research considers how two factors, information load and time pressure, affect the quality of the project‐selection process. We examine quality by observing the decision strategies involved and then relating these strategies to subsequent decision making. An experiment was conducted with experienced information systems auditors using a combination of policy‐capturing and computerized process‐tracing techniques. The participants in our study cope with information overload by accelerating their decision‐making process and adopting noncompensatory decision processes. Contrary to prior research, our process‐tracing analysis suggests that participants rarely filter information, thus implying that decision makers are unable to process all the information. Coping by resorting to noncompensatory strategies did not decrease decision quality unless combined with accelerated information processing. Participants also increase their weight on the software project risk factors that they repeatedly access and that they view for longer periods of time. The theoretical contributions and practical implications regarding what actions managers can take to reduce the negative impact of information overload are discussed.     

Forest soils adjacent to urban interstates: Soil physical and chemical properties,heavy metals,disturbance legacies,and relationships with woody vegetation

While urban ecology is an expanding field of study, some natural areas within the urban environment remain under-examined. These include naturally regenerating forest communities adjacent to urban interstates. In addition, the status of interstate soils and their relationships with the community composition of forested interstate verges has received little ecological study. The purpose of this study was to examine variation in soil conditions along forested interstate corridors in Louisville, KY and to explore the extent to which soil characteristics (e.g., bulk density, pH) and heavy metals (e.g., Pb, Zn) vary with respect to three factors: interstate (e.g., traffic density), surrounding urban environment (e.g., industrial land use), and interstate construction legacies. Additionally, we explored the relationships between several edaphic factors and woody vegetation structure in these forested verges. We found that the degree and direction of the slope of land towards the interstate and the distance to the interstate pavement were strong determinants of soil characteristics and heavy metal concentrations, suggesting that the movement of de-icing salts, heavy metals, and other pollutants from the interstate was important in determining forest soil conditions along urban interstates. Since within our study area these highways did not extend into rural lands, variation in urban land uses and cover within 26 km of the city center was not large enough to explain variation in soil characteristics or heavy metals, except for a positive correlation between chromium and surrounding industrial land use. We did find that past physical soil disturbance caused by interstate construction (e.g., imported fill) left an important legacy on soil characteristics, heavy metal retention, and woody plant growth patterns in forests adjacent to urban interstates. The legacy of interstate construction on the current forest community structure (e.g., lower species richness) and the future forest (e.g., reduced tree regeneration) may further alter ecosystem productivity and ecosystem services provided by these forests and their soils.     

Positive Illusions and the Necessity of a Bright Line Forbidding Psychologist Involvement in Detainee Interrogations

The authors commend Costanzo, Gerrity, and Lykes (2007) and their cogent summary of a number of ethical and scientific considerations relevant to evaluating the proper role of psychologists in national security interrogations of so-called "enemy combatants." From their careful analysis they derive a series of recommendations for the American Psychological Association (APA) and other psychology-related associations, all of which are quite powerful. While supporting these recommendations, the authors also argue that the logic and evidence presented by Costanzo et al. imply, in current legal, political, and organizational circumstances, that psychologists should play no role in the interrogations process. The authors propose that a "bright line" should separate the profession of psychology completely from national security interrogations. The argument is based partly upon ethical considerations, on the practical knowledge available for documenting psychologist participation in interrogations as members of the so-called Behavioral Science Consultation Teams (BSCTs) at Guantánamo, evidence from other locations and sources, and equally upon the social psychological research regarding the interrogation process so adroitly summarized by Costanzo et al.     

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.     

The Panic to Leave: Economic Crisis and the "New Emigration" from Ecuador

Prior to the late 1990s, Ecuadorian international migration was directed primarily toward the United States. Of the estimated 400,000 Ecuadorians living in the United States, most are concentrated in metropolitan New York and many hail from the south–central highlands of Cañar and Azuay Provinces. In the mid– to late–1990s, Ecuador entered a political and economic crisis just as clandestine transportation to the United States became increasingly expensive and dangerous. Within two years Ecuadorian migration diversified radically and a "new emigration" formed. Many thousands of Ecuadorians from throughout the country migrated to Europe, mostly Spain, but also to France, Italy, and The Netherlands. Prior to 1998, few Ecuadorians lived in Europe, but now, Ecuadorians are the largest immigrant group in Madrid and one of the largest in Spain. The migrant stream was led by women and composed of people from a variety of ethnic and socioeconomic backgrounds. Ecuadorians find themselves working in a variety of services (especially women) and negotiating a volatile, even hostile, social, and political environment.
This "new emigration" has numerous implications for Ecuadorian families, the economy, and the nation–state. Understanding the implications requires a comparative approach that examines at least three aspects of the new emigration: the role of gender, the importance of transnational ties and connections, and the emerging roles of state and non–state actors in the formalization of migration.     

Religion and Abortion Attitudes Among U.S. Hispanics: Findings from the 1990 Latino National Political Survey*

Objective. The goal of this article is to examine the relationship between religious involvement, gauged mainly in terms of affiliation and frequency of attendance at services, and abortion attitudes among three major Hispanic subgroups: Mexican Americans, Puerto Ricans, and Cuban Americans. Method. The study analyzes data from the Latino National Political Survey, a sample of over 2,700 U.S. Hispanics completed in 1990. Results. Committed (i.e., regularly attending) Hispanic Protestants, most of whom belong to conservative groups, are more strongly pro‐life than any other segment of the Latino population, and are much more likely than others to support a total abortion ban. Committed Catholics also tend to hold pro‐life views, but they are relatively more likely to endorse an abortion ban that includes exceptions for rape, incest, and threats to the mother's life. Less devoted Catholics and Protestants generally do not differ from religiously unaffiliated Hispanics in their abortion views. There are also modest variations in the links between religious involvement and abortion attitudes across the three Latino subgroups. Conclusion. Religious factors are highly important predictors of Hispanics' preferences regarding abortion policies. Contrary to some previous discussions, it is committed Protestants, more so than Catholics, who are the staunchest opponents of abortion in the Latino population.
