The Inverse Relation Between Risks and Benefits: The Role of Affect and Expertise

Although risk and benefits of risky activities are positively correlated in the real world, empirical results indicate that people perceive them as negatively correlated. The common explanation is that confounding benefits and losses stems from affect. In this article, we address the issue that has not been clearly established in studies on the affect heuristic: to what extent boundary conditions, such as judgments’ generality and expertise, influence the presence of the inverse relation in judgments of hazards. These conditions were examined in four studies in which respondents evaluated general or specific benefits and risks of “affect‐rich” and “affect‐poor” hazards (ranging from investments to applications of stem cell research). In line with previous research, affect is defined as good or bad feelings integral to a stimulus. In contrast to previous research, affect is considered as related both to personal feelings and to social controversies associated with a hazard. Expertise is related to personal knowledge (laypersons vs. experts) as well as to objective knowledge (targets well vs. poorly known to science). The direct comparison of the input from personal and objective ignorance into the inverse relation has not been investigated previously. It was found that affect invoked by a hazard guides general but not specific judgments of its benefits and risks. Technical expertise helps to avoid simplified evaluations of consequences as long as they are well known to science. For new, poorly understood hazards (e.g., stem cell research), expertise does not protect from the perception of the inverse relation between benefits and risks.     

Representing harmony and diversity: media representations of multiculturalism and ethnicity in Singapore

This article investigates multiculturalism and ethnicity in Singapore. The study conducted a qualitative content analysis of articles appearing in the Straits Times newspaper over a three month period in 2010. It was found that multicultural harmony tended to be represented as unnatural, fragile, and requiring government intervention. There also tended to be a focus on distinct and fixed ethnic identities, reflecting an essentialist understanding of ethnicity. These beliefs about the nature of multiculturalism and ethnic identity were reflected in the coverage of three major social issues. These were the perceived needs to maintain the ethnic composition of Singapore’s population, efforts to prevent cultural corruption or neglect, and concerns about the impact of immigration on multicultural harmony.     

A Contingency Analysis of Precarious Organizational Temporariness

This paper extends current understanding of organizational temporariness. The life of a temporary British trade union branch established to recruit Eastern European migrant workers reveals ‘precarious temporariness’, which is less predictable than the ‘planned temporariness’ typically portrayed in the literature. This different type of temporariness was associated with four key contingencies affecting the branch: dispersed governance; bottom‐up initiatives; uncertain resourcing; and an effectuation logic. Analysis of the case extends existing understanding of organizational temporariness and points to an extension of existing theorizing by highlighting the contingent nature of temporariness. The broader managerial implication of the findings is that, for projects facing contingencies of the kind studied, the conventional linear approach of target setting and performance management will be less effective than an ongoing process of communication and consultation.     

AN APPROACH FOR JOINTLY MODELING MULTIVARIATE LONGITUDINAL MEASUREMENTS AND DISCRETE TIME-TO-EVENT DATA

In many medical studies, patients are followed longitudinally and interest is on assessing the relationship between longitudinal measurements and time to an event. Recently, various authors have proposed joint modeling approaches for longitudinal and time-to-event data for a single longitudinal variable. These joint modeling approaches become intractable with even a few longitudinal variables. In this paper we propose a regression calibration approach for jointly modeling multiple longitudinal measurements and discrete time-to-event data. Ideally, a two-stage modeling approach could be applied in which the multiple longitudinal measurements are modeled in the first stage and the longitudinal model is related to the time-to-event data in the second stage. Biased parameter estimation due to informative dropout makes this direct two-stage modeling approach problematic. We propose a regression calibration approach which appropriately accounts for informative dropout. We approximate the conditional distribution of the multiple longitudinal measurements given the event time by modeling all pairwise combinations of the longitudinal measurements using a bivariate linear mixed model which conditions on the event time. Complete data are then simulated based on estimates from these pairwise conditional models, and regression calibration is used to estimate the relationship between longitudinal data and time-to-event data using the complete data. We show that this approach performs well in estimating the relationship between multivariate longitudinal measurements and the time-to-event data and in estimating the parameters of the multiple longitudinal process subject to informative dropout. We illustrate this methodology with simulations and with an analysis of primary biliary cirrhosis (PBC) data.     

Ecological Information Needs for Environmental Justice

The concept that all peoples should have their voices heard on matters that affect their well‐being is at the core of environmental justice (EJ). The inability of some people of small towns, rural areas, minority, and low‐income communities, to become involved in environmental decisions is sometimes due to a lack of information. We provide a template for the ecological information that is essential to examine environmental risks to EJ populations within average communities, using case studies from South Carolina (Savannah River, a DOE site with minority impacts), Washington (Hanford, a DOE site with Native American impacts), and New Jersey (nonpoint, urbanized community pollution). While the basic ecological and public health information needs for risk evaluations and assessments are well described, less attention has been focused on standardizing information about EJ communities or EJ populations within larger communities. We suggest that information needed about EJ communities and populations includes demographics, consumptive and nonconsumptive uses of their regional environment (for example, maintenance and cosmetic, medicinal/religious/cultural uses), eco‐dependency webs, and eco‐cultural attributes. A purely demographics approach might not even identify EJ populations or neighborhoods, much less their spatial relation to the impact source or to each other. Using information from three case studies, we illustrate that some information is readily available (e.g., consumption rates for standard items such as fish), but there is less information about medicinal, cultural, religious, eco‐cultural dependency webs, and eco‐cultural attributes, all of which depend in some way on intact, functioning, and healthy ecosystems.     

Evaluating Risk Communication about Fish Consumption Advisories: Efficacy of a Brochure versus a Classroom Lesson in Spanish and English

Presentation format can influence the way target audiences understand risk-related information. Brochures or fish fact sheets are the methods traditionally used by state agencies to inform the public about fish consumption advisories and the risks from consuming fish. This study examines the efficacy of presenting information about the risks from consuming contaminated fish and shellfish in two different formats: a brochure and classroom presentation. The two instruments were developed and tested in Spanish and English, reflecting the local ethnic composition in the Newark Bay Complex. The instruments were tested on women of child-bearing age at the Women, Infants, and Children Center in Elizabeth, New Jersey. Detailed diagrams were used in both presentations, including contaminated fish species, fish preparation methods, and food chain bioaccumulation and transmission to the fetus. There were few language-related differences in the efficacy of the classroom lesson, and the main ideas were understood by both groups. Where there were significant differences in understanding about the risks from consuming fish or crabs from the contaminated waters of Newark Bay, in all cases the women exposed to the classroom lesson had a better understanding than those who read the brochure. Ninety-six percent of the women who heard the lesson understood that it was unsafe to eat fish from the port, compared to 72% of those reading the brochure. Both formats succeeded in imparting information to most women about the area under advisories, the fish species under advisories, and transmission of toxins to the fetus. Information on fish preparation was recalled less clearly, partly because women were asked to relate methods to reduce the risk from consuming fish from 11 presented, and most recalled only two or three of the list. The advantages and disadvantages of conducting short classes to women of child-bearing age are discussed.     

Anxiety in Adolescence: The Integration of Attachment and Neurobiological Research into Clinical Practice

Attachment theory illuminates aspects of adolescent development and points to critical treatment directions for adolescents. Recent neurobiological research illustrates the importance of integrating physiological understanding into clinical work. The application of attachment theory and neurobiology to treatment is illustrated best through the case example of one adolescent with panic disorder treated in an outpatient setting.     

Trapped in migrants’ sectors? Polish women in the Icelandic labour market

The employment‐driven migrations from Poland to Iceland have largely been pioneered by Polish women. They outnumbered men among Polish residents in this country until the economic boom since 2005 triggered large‐scale male immigration. This trend slowed down with the outbreak of the financial crisis, as the recession severely affected the male‐dominated construction industry. The analysis of Polish female migrants’ working experiences shows that recent inflows are mainly shaped by the nature of labour demand as well as the social policies and care services in Iceland. Although economically integrated, compared with native women Polish women tend to occupy rather disadvantaged positions. They seem concentrated in a few low‐skilled occupations that bring little prestige and low income. On the other hand, they were less affected by the financial crisis, in the sense that many of them maintained work, though some experienced lowering of salaries or reduction of working hours.     

Basking habitat use and response of freshwater turtles to human presence in an urban canal of Central New Jersey

Pressures of rapid development continue to increase, and recreational activities are becoming a prominent driving force in many urban wildlife communities. Freshwater turtles live in many urban environments, yet little attention has been given to the impact of human recreation upon these communities. We examined the response of basking turtles to observer presence along the towpath of a recreational canal in central New Jersey. All species, except for turtles of the family Kinosternidae, were more frequently observed basking on substrate with less than 50 % canopy cover, log substrate was most preferred, and turtles on the towpath side basked an average of 3 m from the towpath. Turtles were vigilant and over 75 % of C. picta, T.S. elegans, and P. rubriventris responded to observer presence by retreating (swimming away). The distance from the towpath turtles were first seen basking by the observer (approach distance) was significantly correlated with the flight-initiation distance (distance of first respond to observer). Nearly 80 % of the variability in flight initiation distance for Kinosternidae was accounted for by the percent canopy cover, percent cloud cover, and height basking above the water. Researchers aiming to quantify and manage human recreational impact on turtles should examine flight-initiation distances. We encourage wildlife managers of urban parks to construct towpaths or recreational areas at a minimum of 7 m from the water’s edge, maintain moderate vegetation in basking areas, and construct additional basking platforms opposite from towpaths or at great distances from human recreational areas.
