Risk Assessment for Invasive Species

Although estimates vary, there is a broad agreement that invasive species impose major costs on the U.S. economy, as well as posing risks to nonmarket environmental goods and services and to public health. The domestic effort to manage risks associated with invasive species is coordinated by the National Invasive Species Council (NISC), which is charged with developing a science-based process to evaluate risks associated with the introduction and spread of invasive species. Various international agreements have also elevated invasive species issues onto the international policy agenda. The World Trade Organization (WTO) Sanitary and Phytosanitary (SPS) Agreement establishes rights and obligations to adhere to the discipline of scientific risk assessment to ensure that SPS measures are applied only to the extent required to protect human, animal, and plant health, and do not constitute arbitrary or unjustifiable technical barriers to trade. Currently, however, the field of risk assessment for invasive species is in its infancy. Therefore, there is a pressing need to formulate scientifically sound methods and approaches in this emerging field, while acknowledging that the demand for situation-specific empirical evidence is likely to persistently outstrip supply. To begin addressing this need, the Society for Risk Analysis Ecological Risk Assessment Specialty Group and the Ecological Society of America Theoretical Ecology Section convened a joint workshop to provide independent scientific input into the formulation of methods and processes for risk assessment of invasive species to ensure that the analytic processes used domestically and internationally will be firmly rooted in sound scientific principles.     

The development and construct validation of a consumer satisfaction questionnaire for psychiatric inpatients.

A consumer satisfaction scale was developed for psychiatric inpatients. The scale was administered to a state-wide sample of (n = 366) patients discharged from acute psychiatric units throughout Missouri. The scale was factor analyzed and given to another sample of (n = 390) discharges. Three out of five factors that were found in the first sample were replicated in a factor analysis of data from the second sample. Acceptable coefficient alphas were obtained on all three factors, demonstrating internal reliability. The three factors were labeled Treatment Effectiveness, Trust of Staff, and Hospital Environment. Comparable levels of satisfaction with prior studies were found on the first general satisfaction factor of Treatment Effectiveness. Subjects discriminated areas of satisfaction by expressing higher levels of dissatisfaction on the factors of Trust of Staff and Hospital Environment.     

INTERPROFESSIONAL RELATIONS AND THE EMERGENCE OF A NEW PROFESSION: Software Engineering in the United States, United Kingdom, and Canada

This article explores the conditions under which interprofessional relations may be characterized by conflict and/or cooperation through a case study of the rise of a software engineering (SWE) profession in the United States, United Kingdom, and Canada. Analysis of professional journal publications produced by the primary computing organizations in all three countries reveals that the development of a SWE profession in the United Kingdom, and to a lesser extent, the United States, has been a collaborative project pursued by engineering and computing organizations. In contrast, the development of SWE in Canada has been characterized by intense interprofessional conflict. The investigation suggests that interprofessional conflict may be mitigated when professionalizing groups seeking to lay claim to the same jurisdiction are similar in terms of their organizational size, outlook, and regulatory status.     

Managing Potential Health Risks from Electric Powerlines: A Decision Analysis Caught in Controversy

Over the past 20 years, several epidemiological studies have found an association between exposure to electromagnetic fields (EMFs) and health effects, including childhood leukemia and adult brain cancer. However, experts strongly disagree about whether this association is causal and, if so, how strong it is. In this article, we examine several alternatives to reduce EMFs from sources of the California power grid, including undergrounding distribution and transmission lines and reconfiguring or rephasing lines. The alternatives were evaluated in terms of the potential health risk reduction, cost, impacts on service reliability, property values, and many other consequences. Because of the uncertainty about an EMF-health link, the main effort was to determine the sensitivity of the decisions to the probability and seriousness of an EMF hazard. User-friendly computer models were developed to allow stakeholders to change the model assumptions and parameters to analyze the impacts of their own assumptions and estimates on the decision. The analysis clearly demonstrated that only four of the many concerns raised by the stakeholders could make a difference in the decision: health risks, costs, service reliability, and property values. Whether undergrounding, moderate alternatives for EMF reduction, or no change was the best decision depended on a few key factors, including the probability that EMF exposure is a hazard, the severity of this hazard, how the EMF reduction measures are financed, and the impacts on property values. While the analysis did not resolve the EMF issues, it showed that even in the most controversial settings, a little analysis goes a long way to clarifying the issues and to focus the debate.     

Research misconduct and crime lessons from criminal science on preventing misconduct and promoting integrity

For 200 years, criminologists theorized that delinquent and criminal acts arise from deviant psychological states (such as irrationality or immorality) and/or social conditions that produce these psychological states. This theoretical perspective, which is being duplicated in most efforts to understand and control research misconduct, has not been productive. More recently, criminological perspectives have emerged, emphasizing situational factors that enhance or restrict the opportunity for illegal or imprudent behavior. These so-called "opportunity" theories have been shown to have practical value in reducing crime rates. We explore the promise of these newer theories for the responsible conduct of research (RCR).     

Male Entry into the Labor Force: Estimates of Occupational Rewards and Labor Market Discrimination*

Causal models of initial occupational rewards for black and white males are developed from the responses of first-year workers in the National Longitudinal Surveys of Labor Market Experience. A comparison of the black and white models shows that while blacks have experienced considerable upward mobility, their income and prestige remain far behind their white counterparts. Two explanations for this racial gap are indicated by the data: (1) blacks begin work with lower levels of key background variables, and (2) racial discrimination in the labor market. Our measurement of racial discrimination in labor market entry accounts for only a small proportion of the gap between black and white levels of rewards; and when compared with earlier research, the data indicate a national trend of decreasing racial discrimination in the labor market.     

Revisiting the stock price impact of quality awards

In an event study, Hendricks and Singhal [Hendricks KB, Singhal VR. Quality awards and the market value of the firm: an empirical investigation. Management Sci 1996;42:415–36.] find evidence that firms that win quality awards are further rewarded with a stock price increase on the day of the award announcement. We revisit Hendricks and Singhal (1996), extend their research and find four reasons why management, owners and analysts should be cautious about expecting an abnormal return when a firm wins a quality award. First, in our sample of Baldrige Award winners, the evidence of a stock price response on the announcement day is only marginally significant. Second, in our sample of State quality award winners, the announcement day relationship between stock returns and winning awards is not significant. Third, in the most recent subperiod, 1992–1997, we find no evidence of positive abnormal returns. Fourth, the marginally significant Baldrige results are actually driven by just four companies. A company-by-company microanalysis reveals that only 50% of the award winners experienced positive abnormal returns. The diminishing stock price response on event day does not necessarily imply a lack of stockholder rewards. Evidence from other studies suggests that the stockholders are rewarded for successful total quality management (TQM) implementation, but the rewards can come long before and after the formal award is presented. From a shareholder value perspective, TQM still matters but the award ceremonies may not.     

Making a difference: ethical consumption and the everyday

Our everyday shopping practices are increasingly marketed as opportunities to ‘make a difference’ via our ethical consumption choices. In response to a growing body of work detailing the ways in which specific alignments of ‘ethics’ and ‘consumption’ are mediated, we explore how ‘ethical’ opportunities such as the consumption of Fairtrade products are recognized, experienced and taken‐up in the everyday. The ‘everyday’ is approached here via a specially commissioned Mass Observation directive, a volunteer panel of correspondents in the UK. Our on‐going thematic analysis of their autobiographical accounts aims to explore a complex unevenness in the ways ‘ordinary’ people experience and negotiate calls to enact their ethical agency through consumption. Situating ethical consumption, moral obligation and choice in the everyday is, we argue, important if we are to avoid both over‐exaggerating the reflexive and self‐conscious sensibilities involved in ethical consumption, and, adhering to a reductive understanding of ethical self‐expression.
