A class of symmetric bivariate uniform distributions

A class of symmetric bivariate uniform distributions is proposed for use in statistical modeling. The distributions may be constructed to be absolutely continuous with correlations as close to±1 as desired. Expressions for the correlations, regressions and copulas are found. An extension to three dimensions is proposed.     

'It is a horrible term for someone': service user and provider perspectives on 'personality disorder'

This paper presents findings from a study exploring the views of people with personality disorder diagnoses and various professionals working with them. After outlining the policy context and the study's conceptual framework, the aims and methods are described. Interviews were conducted with 12 service providers and 10 users. The main findings are then discussed, including user and provider perspectives on the meaning of 'personality disorder' and the strategies and support people use to address their difficulties. Finally, the theoretical implications of the findings are discussed.     

Modelling data from single-photon emission computerized tomography

The completely random character of radioactive disintegration provides the basis of a strong justification for a Poisson linear model for single-photon emission computed tomography data, which can be used to produce reconstructions of isotope densities, whether by maximum likelihood or Bayesian methods. However, such a model requires the construction of a matrix of weights, which represent the mean rates of arrival at each detector of photons originating from each point within the body space. Two methods of constructing these weights are discussed, and reconstructions resulting from phantom and real data are presented.     

The Relationship Between Visioning Behaviours of Leaders and Follower Burnout

This paper investigates whether the perceived visioning behaviours of leaders influence the burnout process experienced by their followers. A structural equation model was used to examine these relationships using a sample of 480 senior managers from an Australian law-enforcement organization. Differences in the relationships between the two factors of visioning behaviour and aspects of burnout were identified. Inspirational motivation (concept-based) reduced the central factor of burnout, namely emotional exhaustion (psychological strain). Inspirational motivation (image-based) had a positive effect on personal accomplishment (self) and reduced depersonalization. The paper discusses the implications for leaders and followers and identifies directions for future research.     

“Either Side of Delphy Bridge”: A deep mapping project evoking and engaging the lives of older adults in rural North Cornwall

This article reports on work to date by an arts practice-led research team exploring older adults’ conceptions of, and connectivity with, the physical, social and cultural landscapes in which they locate themselves. The team is based at the Department of Art and Design, University of the West of England (UWE) and has conducted fieldwork, interviews and small-scale interactions in an area of rural North Cornwall with a view to “deep mapping” older adults’ “lived landscapes” using a variety of practical methods derived from creative arts practices, critical reflection on deep mapping, ethnographic approaches, and referencing a range of theoretical positions. The project forms part of a work package within “Grey and Pleasant Land? An interdisciplinary exploration of the connectivity of older people in rural civic society” (abbreviated below as GaPL), funded by the UK Cross-Research Council ‘New Dynamics of Ageing’ Programme. In what follows we will describe and critically discuss the fieldwork undertaken and the various ways in which the performative interactions and the creative multimedia evocations that draw on the team’s interactions with older people might extend the growing dialogue between deep mapping, visual and other innovative ethnographies, and critical gerontology.     

Is EM really necessary here? Examples where it seems simpler not to use EM

AStA Advances in Statistical Analysis - If one is to judge by counts of citations of the fundamental paper (Dempster in JRSSB 39: 1–38, 1977), EM algorithms are a runaway success. But it is...     

The Social Economy in Bolivia: Indigeneity,Solidarity, and Alternatives to Capitalism

The social economy (SE) is alternatively conceptualized as a third sector (between the private and public sector); or by a typology of the organizations involved (such as cooperatives, non-profit organizations and social enterprises); or by the principles and values driving such activities (such as cooperation, mutual benefit, and democracy). One important consideration is often overlooked, namely that the SE emerges in different forms and with varied emphases depending on location. The SE is ‘place-based’—rooted in specific geographic, historical, cultural, and socioeconomic settings. This article explores the conceptualization of the SE in the Bolivian context from the perspective of government and civil society actors. The research took place after the country recognized the importance of the social, cooperative and community economy in their new constitution and found that the understanding of the SE in Bolivia relates strongly to the country’s indigenous and colonial heritage.     

Allegations of child sexual abuse in parenting disputes: An examination of judicial determinations in the Family Court of Australia

This study examined Family Court of Australia (FCA) judicial determinations in parenting disputes when allegations of child sexual abuse (CSA) are made by an interested party, usually the mother. For the study, 156 published judgments from 2013–2015 were examined to measure how often allegations of CSA are substantiated, suspected to be true, and disbelieved. The characteristics most common in substantiated versus unsubstantiated cases, evidence of abuse presented, and resulting parenting orders were assessed. Findings indicate that, against international comparisons, FCA judges substantiate cases very conservatively, with rates of substantiation much lower than in other studies. Allegations made by mothers against fathers were disproportionately unsubstantiated, as were those which did not fall under the Magellan case management system. Cases where the only evidence of CSA was a child’s disclosure and parent’s allegation were common in both substantiated and unsubstantiated cases, meaning that a lack of other evidence does not preclude a positive finding of risk of CSA by the FCA. Those cases also involving a protection order against the accused were more likely to be substantiated. Confirmation biases and a judicial tendency to err on the side of false negatives are discussed.     

Nativity Seen in the Anthropocene: Contemporary Fieldwork and Subjective Challenges

Ongoing political changes, diasporic mobilities and new communication modalities present anthropologists with novel challenges for conducting ethnographic field work. As both configurations of and expectations for varied forms of social identity change, so too has the notion of the native, what Arjun Appadurai once called the technical preserve of anthropologists. Through reflection on contemporary field work experiences in Kazakhstan, the Philippines and South Korea, this set of papers considers how changing political and cultural regimes, diasporic mobilities and social media also tag the native anthropologist, a concept which can be to the advantage of the researcher, but also can create new problems and complexities for research.
