Demographics, Parenting, and Theory of Mind in Preschool Children

This research examined associations among demographic variables, parenting strategies, and a theory of mind battery including measures of perception, desire, belief, and emotion understanding in 142 preschool‐aged children. In correlational analyses, maternal education and, to a lesser extent, income were associated with a number of aspects of theory of mind. Additionally, mothers’ use of instruction in response to child misbehavior was positively associated with perception and desire understanding whereas mothers’ use of consequences and power assertion were negatively associated with aspects of theory of mind. In regression analyses controlling for children's cognitive ability and age, maternal education continued to be positively associated with perception understanding. Power assertion was negatively associated with belief understanding, but positively associated with emotion understanding. Finally, mothers’ use of consequences in response to child misbehaviors was negatively related to emotion understanding.     

Plurality of Worlds, Plurality of Risks

Risk management decisions are not made only on the basis of expert risk assessment. In numerous instances, public controversy erupts, questioning the results of previous risk assessment procedures and shaping the development of risk management episodes. This article presents a case study of risk management in the context of a 1980s controversy over aerial spraying against a spruce budworm epidemic in Quebec and draws some general conclusions concerning the relationship between risk analysis and public controversies. Actors in public controversies define risks more broadly than risk assessment experts. Moreover, public controversies only partly concern issues of risk. They are first and foremost debates about social choices in which actors carry with them a multidimensional social experience of technology, trust, credibility and decision-making institutions. This experience contributes to the construction of a plurality of emergent representations of what is at stake in a controversy, referred to in this paper as "worlds of relevance." Analysis shows that in any given public controversy, there are not just two parties arguing against each other. Rather, several "worlds of relevance" can be found that link, in a variety of ways, a variety of entities not necessarily shared by all these worlds. Each "world of relevance" presents a different definition of what the issues and the stakes of the controversy are. Risks are only part of the picture, and they are embedded in "worlds of relevance" from which they take their significance. The successful management of a controversy entails the association of entities from different worlds.     

A note on the relationship of interdependent action to the optimality of certain voting decisions

While the theory of public goods points to socially suboptimal contributions by agents acting under Cournot assumptions, this externality can be rectified by the introduction of positive interdependence of actions to the individual's choice calculus. This paper draws attention to the fact that the institution of democratic voting is itself a means of transforming the individual calculus in such a way that parameter changes are evaluated as simultaneous adjustments by the group, on the side of benefits, but by the individual only, on the side of costs, thus generating optimal parameter preference in the case of identical agents.     

Assessing gamma frailty models for clustered failure time data

Proportional hazards frailty models use a random effect, so called frailty, to construct association for clustered failure time data. It is customary to assume that the random frailty follows a gamma distribution. In this paper, we propose a graphical method for assessing adequacy of the proportional hazards frailty models. In particular, we focus on the assessment of the gamma distribution assumption for the frailties. We calculate the average of the posterior expected frailties at several followup time points and compare it at these time points to 1, the known mean frailty. Large discrepancies indicate lack of fit. To aid in assessing the goodness of fit, we derive and estimate the standard error of the mean of the posterior expected frailties at each time point examined. We give an example to illustrate the proposed methodology and perform sensitivity analysis by simulations.     

Understanding the September 11 Terrorist Attack on America: The Role of Intergroup Theories of Normative Influence

The present article analyzes the September 11 terrorist attack on the World Trade Center and the Pentagon in terms of current theories of normative influence in intergroup conflict. The (conflicting) implications of various social psychological models of decision making for Western and American attempts to reduce the likelihood of further attacks are delineated. We examine the implications of social identity models and models of outgroup normative influence, as well as dynamic models of intergroup behavior that focus on the polarizing effects of outgroup hostility. The influence of Western responses is distinguished for various target audiences, including not only the terrorists, but also pro-Western Muslims in North America and Europe, unaligned Muslims, and Muslims with anti-American feelings who do not endorse terrorism.     

Annual and seasonal habitat use of Columbian black-tailed deer in urban Vancouver, Washington

We investigated habitat use of Columbian black-tailed deer in urban Vancouver, Clark County, Washington, at 3 spatial scales: (1) placement of the annual home range within the landscape mosaic, (2) annual and seasonal locations of deer within the annual home range, and (3) short-term use of critical habitats (fawning areas) within seasonal ranges. Annual home range sizes of deer were 162 ha (SD = 133; 95% minimum convex polygon; MCP) and 266 ha (SD = 228; 95% adaptive kernel; AK) for does, and 756 ha (SD = 290; MCP) and 1,235 ha (SD = 382; AK) for bucks. Home range composition of does did not differ from the study area; home ranges of bucks contained more Natural ecological land-use cover types (ELUs) than did the study area. Within home ranges, both does and bucks used Natural ELUs more often than expected by their occurrence in the home range, both annually and seasonally. During the fawning season, does were also found in Natural ELUs more often than expected. Clark County-designated habitat corridors differed from both the study area and deer home ranges in habitat composition, primarily by containing more Natural and other undeveloped ELUs. Deer were located in habitat corridors more than expected. Deer in urban areas appear to use undeveloped habitat types for security. Management that maintains Natural ELUs, such as establishment of wildlife corridors, can provide important habitat components for black-tailed deer in urban habitats.     

The Metrics of Societal Happiness

Growing interest in the measurement of subjective well-being (SWB) has also been accompanied by scientific debate on the optimal method for measuring SWB. The momentary perspective, which is represented by the ecological momentary assessment (EMA) and day reconstruction method (DRM), emphasizes the momentary experiences and aims to measure SWB in an objective manner via the aggregation of happiness levels over time and activities. The global reporting perspective emphasizes the subjective evaluation of life experiences and aims to capture the overall evaluation using retrospection or global evaluations. We discuss the strengths and weaknesses of these different perspectives and methods by examining conceptual, methodological, and practical issues. We propose adopting a multi-method assessment approach to SWB that uses both perspectives and the corresponding methods in a theory-driven and complementary manner. For the purposes of measuring and tracking SWB of societies, we also call for more research on the reliability and validity of EMA and DRM.
