Bargaining over waiting time in ultimatum game experiments

While preference-based explanations play an increasing role in economics and sociology, the accurate measurement of social preferences deserves more attention. Most laboratory experiments measure social preferences by studying the division of “a cake that nobody had to bake” (Güth and Kliemt, 2003). This article reports results of the first ultimatum game experiment with bargaining over waiting time. The experiment was created to avoid effects of windfall gains. In contrast to donated money, time is not endowed by the experimenter and implies a natural loss to subjects. This allows for a better measurement of the inherent conflict in the ultimatum game. We implemented three anonymity conditions; one baseline condition, one condition with anonymity among subjects and one double-blind condition in which the experimenter did not know the division of waiting time. While we expected to observe less other-regarding behavior in ultimatum game bargaining over time, our experimental results rather confirm previous ultimatum game experiments, in which people bargained over money. The modal offer was half of the waiting time and only one offer was rejected. Interestingly, anonymity did not change the results significantly. In conclusion, our experiment confirms other-regarding behavior in the ultimatum game.     

Two-stage approaches to the analysis of occupancy data I: the homogeneous case (analysis of occupancy data)

Abstract

Occupancy models are used in statistical ecology to estimate species dispersion. The two components of an occupancy model are the detection and occupancy probabilities, with the main interest being in the occupancy probabilities. We show that for the homogeneous occupancy model there is an orthogonal transformation of the parameters that gives a natural two-stage inference procedure based on a conditional likelihood. We then extend this to a partial likelihood that gives explicit estimators of the model parameters. By allowing the separate modeling of the detection and occupancy probabilities, the extension of the two-stage approach to more general models has the potential to simplify the computational routines used there.     

Measuring Knowledge,Attitudes and Behaviours Concerning Sustainable Development among Tenth Grade Students in Manitoba

In this paper we present standardized measures of tenth grade students’ knowledge, attitudes and behaviours concerning sustainable development as those concepts are understood in the United Nations Educational, Scientific and Cultural Organization, and we test the hypothesis that knowledge and favourable attitudes toward SD lead to favourable behaviours. Using a fairly representative random sample of 1,551 tenth grade students from the province of Manitoba, Canada, we crafted 3 indexes. There is a 20-item Index of Knowledge of SD with a good Cronbach alpha = 0.89, a 15-item Index of Attitudes Favourable Toward SD with alpha = 0.84 and a 15-item Index of Behaviours Favourable Toward SD with an alpha = 0.83. About 21% of the variation in our Behaviours Index scores could be accounted for by our Knowledge Index and Attitudes Index scores.     

Reflective Practices for Engaging in Trauma-Informed Culturally Competent Supervision

ABSTRACT

Race, ethnicity, and culture are critical components that affect and shape the supervisory relationship, yet literature about ways to acknowledge and actively engage them from a trauma-informed approach has been limited. To enhance the discussion of this issue, this article first reviews leading theoretical aspects of supervision designed to train practitioners in the field of mental health, followed by a discussion of race, ethnicity, and culture in supervision and, finally, provides reflective practices for engaging in trauma-informed culturally competent supervision.     

Sports fans as crisis communicators on social media websites

Previous research has analyzed how organizations publicly respond in crisis situations. This study addresses a sports crisis, the University of Miami NCAA investigation, as an avenue for exploring how fans become surrogates for organizational crisis responses via the social media entity, Twitter. Using Coombs's (2007) strategy for reputation repair, analysis of 75 highly identified Miami fans with over 42,000 Twitter followers shows that fans were most likely to engage in (a) ingratiation, (b) reminder, (c) attack the accuser, and (d) divert attention as primary methods of coping with the scandal. New methods for reputation repair were also found within the analysis and implications for organizations, academic institutions, sports research, and crisis communication theory are articulated.     

Adverse Childhood Experiences and Healthcare Costs in Adult Life

ABSTRACT

The current study aims to present the prevalence of adverse childhood experiences and examine the healthcare costs associated with primary, allied, and specialist healthcare services. The Australian Longitudinal Study on Women’s Health is a general health survey of four nationally representative age cohorts. The current study uses 20 years of survey and administrative data (1996–2015) from the cohort born 1973–1978. Overall, 41% of women indicated at least one category of childhood adversity. The most commonly reported type of childhood adversity was having a household member with a mental illness (16%), with the most commonly reported ACES category being psychological abuse (17%). Women who had experienced adversity in childhood had higher healthcare costs than women who had not experienced adversity. The healthcare costs associated with experiences of adversity in childhood fully justify a comprehensive policy and practice review.     

A Test of Excellent Leadership in Public Relations: Key Qualities,Valuable Sources,and Distinctive Leadership Perceptions

To better understand leadership in public relations and explore its value in successful communication management, this article captured the perceptions of mid- and senior-level public relations executives (N = 222) regarding the important qualities and dimensions of excellent leadership in the practice. According to study participants, strategic decision-making capability, problem-solving ability, and communication knowledge and expertise are the three most important qualities of excellent leadership. In addition, respondents said that on-the-job experiences, individual initiative and desire, and role models are the most valuable sources of leadership skills and development. About half of the respondents indicated that excellent leaders in public relations are different from leaders in other fields in three ways: They must hold a compelling vision for communication, possess comprehensive understanding of media and information systems, and effectively develop and implement strategic communication plans. Professional women and men in the study viewed excellent leadership in more or less similar ways. The study advances understanding of leadership in the field, which has been little explored in the public relations literature.     

“Some of My Children Are Worth More Than Others”: Perceptions of Nonresidential Fathers with Second Families as to the Fairness of the Australian Child Support Agency's Handling of First Family Child Support Financial Arrangements

One in three Australian marriages end in divorce, and over half of such divorces involve children. Research indicates that men tend to repartner within 1 to 2 years of a divorce and women within 3 to 5 years. A significant issue for repartnered men is the provision of financial support for children from both their first and second families. Although only 6% of all Australian first family children spend near/equal time (shared care) after divorce with both parents, fathers in Australia are mandated under child support legislation to provide financial support for their first family children, whether they reside with them or not. However, it is argued by this study's nonresidential fathers that the Child Support Agency, when considering the level of financial support for first family children, tends to overlook the needs of second family children, thus creating an advantaged and disadvantaged set of siblings. This finding is reviewed through a distributive justice theory lens. Finally, some future directions for research aimed at exploring the impact of Child Support Legislation on second families are suggested.     

Formerly Homeless,Older Women's Experiences with Health,Housing, and Aging

The perspectives of formerly homeless, older women are absent in the academic literature on aging and homelessness. In this study, a group of formerly homeless women, aged 45 years and older were surveyed (N = 15) and interviewed (n = 11) about their experiences with health, housing, and aging. The qualitative themes to be explored include the women's perceptions of their current health, coping with low incomes, dealing with addictions to alcohol and drugs, and the importance of supportive housing and other community services. The female participants' views on adapting to home, planning for their elderly years, and views on growing older are also explored.
