Varying the intensity of competition in a multiple prize rent seeking experiment

We experimentally test a rent seeking model under five levels of competition. At one extreme, a subject’s probability of winning a prize is equal to her share of the total expenditures. At lower levels of competition, a subject’s probability of winning is affected more by her own expenditures than by the expenditures of others. Predicted expenditure levels are positively associated with higher levels of competition. Consistent with previous rent seeking experiments, we find that subjects spend significantly more than the Nash equilibrium prediction at all levels of competition. However, expenditure patterns generally follow the Nash prediction; expenditures decrease as the level of competition decreases. Our experimental design also includes a lottery choice experiment to control for subjects’ risk preference. We find that subjects who are more risk averse spend significantly less in the contest and this effect is particularly strong for female subjects.     

Brexit and Strand Three of the 1998 Agreement: The Three Faces of East-West

Under Strand Three of the 1998 Belfast ‘Good Friday’ Agreement, institutions were set up to promote the ‘harmonious and mutually beneficial development’ of the ‘totality of relationships’ between the peoples and governments of Ireland and the UK, including its devolved administrations and Crown Dependencies. According to the text of the 1998 Agreement this ‘east-west’ dimension was to have two elements with corresponding institutions: an intergovernmental one reflected in the British-Irish Intergovernmental Conference (BIIC) and an interjurisdictional one reflected in the British-Irish Council (BIC). These Strand Three institutions were designed to provide fora for, respectively, intergovernmental cooperation on ‘non-devolved Northern Ireland matters’ in the case of the BIIC and information exchange and cooperation ‘on matters of mutual interest within the competence of the relevant Administrations’ in the case of the BIC. Nowhere in the 1998 Agreement text is the concept of ‘east-west’ used to refer to relations between Northern Ireland and Great Britain. Yet, in the wake of Brexit, and in the midst of controversy over the implications of the Protocol on Ireland / Northern Ireland, relations between Great Britain and Northern Ireland (GB–NI) have been newly framed as ‘east-west’. The creation of this new discursive face of ‘east-west’ relations marks an important, but little discussed, impact of Brexit on the political and constitutional landscape of the UK and Ireland. Against this backdrop, this article considers the impacts of Brexit, and the Protocol, on three faces of ‘east-west’ relations—the BIIC, the BIC and, newly, GB–NI—and discusses their implications for the future of Strand 3 institutions and the ‘totality of relationships’ they represent.     

Perceived infallibility of detection dog evidence: implications for juror decision-making

This study focuses on the trust that potential jurors have in unsubstantiated evidence and the implications of such trust for legal decision-making. We examined whether participants’ motivation to think deeply (‘need for cognition,’ NC) and belief in science moderated their trust in potentially fallible detection dog evidence when selecting a verdict in a trial scenario. A detection dog twice indicated the presence of drugs in the scenario, yet no drugs were actually found. Those who chose a guilty verdict without drugs present featured stronger beliefs in detection dog evidence. They were also more confident that a dog alert indicated the presence of drugs, even though the scientific literature actually shows that detection dog evidence is subject to biases and other challenges to reliability. Our findings indicate that an unsubstantiated belief and trust in detection dog evidence may negatively influence juror decision-making, which may, in turn, pose consequences for fairness and justice. Participants believed that detection dogs provide powerful and reliable evidence, and these beliefs were clearly associated with stronger beliefs in science. These findings, therefore, raise serious concerns about jurors’ indiscriminate trust in forensic evidence, be it detection dog evidence or other lines of evidence presented in court.     

Parent-Child Agreement on Parent-to-Child Maltreatment

Parent-child agreement on child maltreatment was examined in a multigenerational study. Questionnaires on perpetrated and experienced child maltreatment were completed by 138 parent-child pairs. Multi-level analyses were conducted to explore whether parents and children agreed about levels of parent-to-child maltreatment (convergence), and to examine whether parents and children reported equal levels of child maltreatment (absolute differences). Direct and moderating effects of age and gender were examined as potential factors explaining differences between parent and child report. The associations between parent- and child-reported maltreatment were significant for all subtypes, but the strength of the associations was low to moderate. Moreover, children reported more parent-to-child neglect than parents did. Older participants reported more experienced maltreatment than younger participants, without evidence for differences in actual exposure. These findings support the value of multi-informant assessment of child maltreatment to improve accuracy, but also reveal the divergent perspectives of parents and children on child maltreatment.     

Mother–infant separations in prison. A systematic attachment-focused policy review

Abstract

Mothers in prison separated from their young children are an overlooked group. Attachment theory could provide a useful model to underpin interventions and better support women affected by separation from their infants. Current policy draws on a limited body of evidence and research has developed considerably since its first design. This review systematically searched all relevant UK prison policy and government documents with regards to mother and child separation in prison and analysed the extent to which these documents draw on attachment theory. Following initial searches, 58 documents were thematically analysed. Attachment was implicitly referred to in most documents but only explicitly mentioned in four. Global themes identified included ‘separation as trauma’. However, document groups varied in focusing either on the mother or the child and there were no joint perspectives. Developing and researching specific attachment-informed interventions might be one way forward as would further attachment-based research in this area.     

School-Based Extracurricular Activity Involvement and Adolescent Self-Esteem: A Growth-Curve Analysis

Research on adolescent self-esteem indicates that adolescence is a time in which individuals experience important changes in their physical, cognitive, and social identities. Prior research suggests that there is a positive relationship between an adolescent??s participation in structured extracurricular activities and well-being in a variety of domains, and some research indicates that these relationships may be dependent on the type of activities in which adolescents participate. Building on previous research, a growth-curve analysis was utilized to examine self-esteem trajectories from adolescence (age 14) to young adulthood (age 26). Using 3 waves of data from National Longitudinal Study of Adolescent Health (n = 5,399; 47.8% male), the analysis estimated a hierarchical growth-curve model emphasizing the effects of age and type of school-based extracurricular activity portfolio, including sports and school clubs, on self-esteem. The results indicated that age had a linear relationship with self-esteem over time. Changes in both the initial level of self-esteem and the growth of self-esteem over time were significantly influenced by the type of extracurricular activity portfolio. The findings were consistent across race and sex. The results support the utility of examining the longitudinal impact of portfolio type on well-being outcomes.     

Understanding juror perceptions of forensic evidence: investigating the impact of case context on perceptions of forensic evidence strength

The most widely accepted model of juror decision making acknowledges the importance of both the case-specific information presented in the courtroom, as well as the prior general knowledge and beliefs held by each juror. The studies presented in this paper investigated whether mock jurors could differentiate between evidence of varying strengths in the absence of case information and then followed on to determine the influence that case context (and therefore the story model) has on judgments made about the strength of forensic DNA evidence. The results illustrated that mock jurors correctly identified various strengths of evidence when it was not presented with case information; however, the perceived strength of evidence was significantly inflated when presented in the context of a criminal case, particularly when the evidence was of a weak or ambiguous standard. These findings are discussed in relation to the story model, and the potential implications for real juries.
