Aggregate age-at-marriage patterns from individual mate-search heuristics

The distribution of age at first marriage shows well-known strong regularities across many countries and recent historical periods. We accounted for these patterns by developing agent-based models that simulate the aggregate behavior of individuals who are searching for marriage partners. Past models assumed fully rational agents with complete knowledge of the marriage market; our simulated agents used psychologically plausible simple heuristic mate search rules that adjust aspiration levels on the basis of a sequence of encounters with potential partners. Substantial individual variation must be included in the models to account for the demographically observed age-at-marriage patterns.     

Advocacy for Black and Minority Ethnic Communities: Understandings and Expectations

Recent policy has promoted ‘advocacy’ as a meansof promoting social justice for many disadvantaged groups. Yet‘advocacy’ is a contested concept, and the understandingsthat members of disadvantaged groups themselves have of advocacyhave rarely been explored. Previous research indicates thatunderstandings may vary considerably. Using empirical evidencefrom research conducted in Glasgow, Scotland, this paper examinesthe understandings and expectations of ‘advocacy’held by black and minority ethnic (BME) service providers andpotential service users. The BME service providers believedthat they were offering advocacy, and did so in the contextof a marginalized position for their services. The BME communitymembers supported the development of advocacy services, buttheir own marginalization was in many ways reinforced by servicesthey were already using. They had clear ideas about appropriateadvocacy services for their situation. These ideas were groundedin their current situation, and did not necessarily conformto dominant ideas about advocacy. In conclusion, the prospectsfor successful advocacy are assessed.     

Psychological issues in euthanasia, suicide, and assisted suicide

This paper reviews various life-ending techniques such as euthanasia, suicide, and assisted suicide in order to better address the psychological issues related to these actions. Specific attention is paid to investigating when a death is deemed to be appropriate and the role that the level of appropriateness should play in the decisions of individuals to terminate a life. In addition, a number of additional psychological concepts such as locus of control and subjective norms are examined in terms of their importance for decisions regarding euthanasia and suicide.     

Volunteers, families and children in need: an evaluation of Family Friends

This paper explores the findings from a small‐scale research project that analysed the impact of Family Friends – a voluntary agency that provides support to families under stress who have children aged between 5 and 11 years. The study, funded by Family Friends, evaluated service users’ perceptions of the support they received, specifically in relation to the significance and impact of the volunteer befrienders. The research identified that there are a proportion of families in need who fail to attract services from mainstream statutory agencies. It also identified that the Family Friends voluntary agency makes a particular contribution to service provision by offering a friendly, non‐stigmatizing, caring and responsive service.     

Statistical Analysis for the Inverse Trinomial Distribution

This article considers parameter estimation, goodness of fit, likelihood ratio and score tests, and model selection by Akaike information criterion for the inverse trinomial (IT) distribution, a classical one-dimensional random walk distribution. The IT distribution has a cubic variance function of the mean and is a generalization of the negative binomial distribution. Basic distributional properties and expressions for the probability mass function, recurrence formula, moments, and score functions are also presented.     

Novel biotechnologies for eradicating wasps: seeking Māori studies students’ perspectives with Q method

Aligned with the New Zealand government’s ‘Predator-Free 2050’ target for Aotearoa New Zealand, National Science Challenge: Our Biological Heritage supports research into five distinct ‘novel biotechnological controls’ of exotic wasps. A framing question within this project is which controls are considered ‘socially acceptable’ and thus suitable for further development to control and potentially eradicate introduced wasps? How can the public answer this question without first engaging with complex technologies? Can they develop and express an informed view that still reflects their ‘gut’ reactions and unique positions? To model and explore the views of an ‘informed public’, university students in Māori studies engaged in reflection, writing and mapping activities; choice and ranking exercises; Q Method; and focus group interviews. Amongst the interviewees, Q Method analysis distinguished three ‘factors’, describing unique viewpoints: those who see the potential of biotechnologies, those who are in doubt about them and those in a position of trust in scientists. Overall, the group see potential in new biotechnologies for wasps but are wary of political, economic and social decision-making mechanisms.
