A Cue Utilization Approach for Investigating Harvest Decisions in Commons Dilemmas

Hierarchical linear modeling (HLM) is introduced as a new tool for investigating decision making in commons dilemmas. University undergraduates ( N  = 171) managed a virtual fishery, with 2 computer-simulated fishers, over 60 seasons. Level 1 HLM analyses revealed that participants took significantly more fish during seasons when feedback suggested fish stocks, fish value, and fishing expenses were high; and when noncooperative and cooperative others had taken more fish and fewer fish, respectively, in the previous season. Level 2 analyses produced several cross-level interactions, indicating that participants' use of feedback information varied as a function of their social values and environmental attitudes.     

Epidemiological considerations in transgender health: A systematic review with focus on higher quality data

Abstract

Background: High quality data pertaining to the size of the transgender and gender diverse (TGD) population are scant, however, several recently published studies may provide more reliable contemporary estimates.

Aims: To summarize the estimated number and proportion of TGD individuals overall and across age groups, based on most accurate data.

Methods: This systematic review focused on recent studies (published from 2009 through 2019) that utilized sound methodology in assessing the proportion of TGD people in the general population. Publications were included if they used clear definitions of TGD status, and calculated proportions based on a well-defined sampling frame. Nineteen eligible publications represented two broad categories of studies: those that used data from large health care systems; and those that identified TGD individuals from population surveys.

Results: Among health system-based studies, TGD persons were identified using relevant diagnostic codes or clinical notes. The proportions of individuals with a TGD-relevant diagnosis or other recorded evidence ranged between 17 and 33 per 100,000 enrollees. In population surveys TGD status was ascertained based on self-report with either narrow or broad definitions. The survey-based estimates were orders of magnitude higher and consistent across studies using similar definitions. When the surveys specifically inquired about ‘transgender’ identity, the estimates ranged from 0.3% to 0.5% among adults, and from 1.2% to 2.7% among children and adolescents. When the definition was expanded to include broader manifestations of ‘gender diversity’, the corresponding proportions increased to 0.5-4.5% among adults and 2.5-8.4% among children and adolescents. Upward temporal trends in the proportion of TGD people were consistently observed.

Conclusions: Current data indicate that people who self-identify as TGD represent a sizable and increasing proportion of the general population. This proportion may differ, depending on inclusion criteria, age, and geographic location, but well-conducted studies of similar type and design tend to produce comparable results.     

Strong body,clear mind: Physical activity diminishes the effects of supervisor interpersonal injustice

We integrate exercise physiology tenets with self-regulation theory to explain how physical activity diminishes the effects of supervisor interpersonal injustice. We posit that individuals can help prevent self-regulation depletion from interpersonal injustice when they engage in physical activity. In Study 1, we manipulated physical activity and interpersonal injustice in a laboratory setting, and in Study 2, utilizing a two-week experience sampling method we examined how employees reacted differently to daily interpersonal injustice as a function of their general level of physical activity engagement. Our results demonstrate that both acute and chronic levels of physical activity attenuate the effects of supervisor interpersonal injustice episodes on self-regulation depletion, which subsequently reduces social undermining directed toward the supervisor. Our findings highlight the theoretical and practical significance of physical activity for interpersonal injustice and for organizations in general.

Computational Representation of Practical Argument

In this paper we consider persuasion in the context of practical reasoning, and discuss the problems associated with construing reasoning about actions in a manner similar to reasoning about beliefs. We propose a perspective on practical reasoning as presumptive justification of a course of action, along with critical questions of this justification, building on the account of Walton. From this perspective, we articulate an interaction protocol, which we call PARMA, for dialogues over proposed actions based on this theory. We outline an axiomatic semantics for the PARMA Protocol, and discuss two implementations which use this protocol to mediate a discussion between humans. We then show how our proposal can be made computational within the framework of agents based on the Belief-Desire-Intention model, and illustrate this proposal with an example debate within a multi agent system.     

Regret and the negative evaluation of decision outcomes in major depression

Disruption of normal emotional experience is central to the phenomenology of depression. Twenty-three depressed outpatients and 23 control subjects performed a computerized decision-making task, during which affective ratings were assessed online to identify various dimensions of emotional experience. We sought to contrast regret (the comparison of the outcomes of selected and nonselected options) with the general negative appraisal of task events. The experience of regret was reduced in depressed patients, an effect that was particularly related to self-reported apathy scores. In an exploratory analysis, we observed that females had a general downward shift in their ratings, as compared with males, but disappointment and regret effects were of similar magnitude. The possible contribution of the orbitofrontal cortex to the phenomenology of regret is discussed.

Implicit and explicit prejudice in the 2008 American presidential election

The 2008 US presidential election was an unprecedented opportunity to study the role of racial prejudice in political decision making. Although explicitly expressed prejudice has declined dramatically during the last four decades, more subtle implicit forms of prejudice (which come to mind automatically and may influence behavior unintentionally) may still exist. In three surveys of representative samples of American adults, explicit and implicit prejudice were measured during the months preceding the election. Both explicit and implicit prejudice were significant predictors of later vote choice. Citizens higher in explicit prejudice were less likely to vote for Barack Obama and more likely to vote for John McCain. After controlling for explicit prejudice, citizens higher in implicit prejudice were less likely to vote for Obama, but were not more likely to vote for McCain. Instead, they were more likely to either abstain or to vote for a third-party candidate rather than Obama. The results suggest that racial prejudice may continue to influence the voting process even among people who would not endorse these attitudes.     

Depressive symptomatology and coronary heart disease in Type I diabetes mellitus: a study of possible mechanisms.

Recent evidence has suggested that depressive symptomatology is a risk factor for the development of coronary heart disease (CHD) in patients with diabetes mellitus, although little is understood about mechanisms that may explain this association. The Pittsburgh Epidemiology of Diabetes Complications (EDC) Study is a natural history study of 658 men and women with childhood-onset Type I diabetes. Participants from the EDC Study who reported the fewest depressive symptoms on the Beck Depression Inventory at baseline examination were least likely to develop CHD over 10 years. Differences in insulin resistance, autonomic dysregulation, inflammation, smoking, and complications associated with Type I diabetes appear to help explain this relationship. Future research should clarify causal pathways between depressive symptomatology, behavioral and physiological processes, and CHD.
