The star-shaped Λ-coalescent and Fleming–Viot process

The star-shaped Λ-coalescent and corresponding Λ-Fleming–Viot process, where the Λ measure has a single atom at unity, are studied in this article. The transition functions and stationary distribution of the Λ-Fleming–Viot process are derived in a two-type model with mutation. The distribution of the number of non-mutant lines back in time in the star-shaped Λ-coalescent is found. Extensions are made to a model with d types, either with parent-independent mutation or general Markov mutation, and an infinitely-many-types model, when d → ∞. An eigenfunction expansion for the transition functions is found, which has polynomial right eigenfunctions and left eigenfunctions described by hyperfunctions. A further star-shaped model with general frequency-dependent change is considered and the stationary distribution in the Fleming–Viot process derived. This model includes a star-shaped Λ-Fleming–Viot process with mutation and selection. In a general Λ-coalescent explicit formulae for the transition functions and stationary distribution, when there is mutation, are unknown. However, in this article, explicit formulae are derived in the star-shaped coalescent.     

‘There is always this feeling of otherness’: exploring the lived experiences of visually impaired immigrant women in Canada

This paper explores the experiences of immigrant women with visual impairment in the Greater Toronto and Hamilton Area (GTHA) of Canada. Conceptually, the paper draws from feminist disability theory and critical scholarship on blindness to consider the discursive and material processes shaping women’s experiences across different socio-cultural contexts. Empirically, the paper draws from in-depth interviews with seven women. The analysis is organized around three themes. The first explores women’s understandings of visual impairment. The second examines the ways in which women’s experiences of visual impairment are shaped by meanings and attitudes that circulate within their cultural communities, and the extent to which immigration might challenge or reinforce these meanings. The third examines the shifting barriers and opportunities women face with respect to social and economic participation. We close by identifying the conceptual implications of our research.     

Listening to the voices of children: understanding the human rights priorities of children with disability in Vanuatu and Papua New Guinea

In developing countries, children with disability lack basic services yet their voices are missing in the development agenda. This article reports on research to investigate the human rights needs and priorities of 89 children with disability aged 5–18 years in Vanuatu and Papua New Guinea. An accessible and inclusive research method was developed to enable children with diverse disabilities to communicate their own views via visual, audio and tactile means. Data were analysed in relation to the Articles of the Convention on the Rights of Persons with Disabilities, identifying a wide range of priority areas including recreation, leisure and cultural life; employment; home and family life; and education. It is proposed that policy and programme responses must take a holistic view of children and their needs, affirming but thinking beyond the importance of education, to address the complexity of the systemic disadvantage faced by children with disability.     

“Facing” leaders: Facial expression and leadership perception

This experimental study investigated the effect of a leader's expression of happy versus nervous emotions on subsequent perceptions of leadership and ratings of traits associated with implicit leadership theories (ILTs). Being fast and universally understood, emotions are ideal stimuli for investigating the dynamic effects of ILTs, which were understood in this study in terms of the constraints that expressed emotions impose on the connectionist networks that activate ILTs. The experimental design contrasted videotaped and still frame presentations of a leadership event; however, this methodological factor had no significant effects and analyses were thus collapsed across this factor. Key findings were that the expression of a happy versus nervous emotion at the end of a problem-solving sequence had multiple effects: happy emotions resulted in higher leadership ratings, higher trait ratings, greater correlations among trait ratings, and greater dependence of trait ratings on leadership perceptions. An exploratory model suggested that leadership impressions mediated the effects of facial emotions on trait ratings. The discussion further links the study findings with interpretations in terms of ILTs and many types of constraints on these cognitive structures. It also suggests ways to integrate these ideas with advances in neuroscience research.     

Testing the Vision: Preschool Settings as Places for Meeting,Bonding and Bridging

The OECD (2006 Starting Strong II: Early Childhood Education and Care. OECD Publishing: Paris) envisions early childhood education and care settings as meeting places for diverse social groups; places that build social capital. This vision was assessed in a comparison of three preschools types: full‐fee paying, subsidised‐fee and publicly funded. The social composition within each was examined and the connectedness of the children (n = 472) who attended compared. Publicly funded preschools had more socially diverse populations. The quantity of social connectedness did not differ but children in publicly funded preschools described higher quality social relationships. Not all preschool settings are socially diverse but, where they are, the quality of relationships is highest.     

Gay guys using gay language: friendship,shared values and the intent‐context‐effect matrix

This article draws on in‐depth interviews with 35 openly gay male undergraduates from four universities in England to develop an understanding of the changing nature of language related to homosexuality. In addition to finding a diminution in the prevalence of homophobic language, we demonstrate that participants maintain complex and nuanced understandings of phrases that do not use homophobic pejoratives, such as ‘that's so gay’. The majority of participants rejected the notion that these phrases are inherently homophobic, instead arguing that the intent with which they are said and the context in which they are used are vital in understanding their meaning and effect. We conceptualize an intent‐context‐effect matrix to understand the interdependency of these variables. Highlighting the situated nature of this matrix, we also demonstrate the importance of the existence of shared norms between those saying and hearing the phrase when interpreting such language.     

Public relations critical intersections special section introduction

The theme of this special section arose from the idea that interdisciplinary interactions, or the cross-fertilization of methods, philosophies, theories, and modes of practice across disciplines, can open out productive ways of addressing complex issues and wicked problems. Our call for papers reached out to public relations scholars and to researchers in other fields to submit articles at these generative intersections at different time. They were invited to reflect on traditional concerns, or current issues, or projected trends in public relations and elsewhere. As editors making a call to open boundaries, we invited participation along a spectrum of possible intersections whether of content, methods, pedagogy or technology. Taking different positions on that spectrum, the articles in the section examine the nature, engagement and evaluation of intersections. In writing this introduction, the editors took an overview of the articles in the light of three fundamental questions: “How and where does interdisciplinarity occur in public relations?”; “Are there indications of how public relations intersects with other fields to engage existing and potential future challenges?”; and “What principles might serve to evaluate answers to questions one and two?” In addition, we explore how each of the selected intersections in the articles might add value to public relations as a discipline and a practice.     

A Boy’s Journey and the Journey to Freedom*

The journey to freedom is a literary genre that involves a realization of oppression, a decision to leave, a journey that is both physical and moral, a wilderness experience, a self‐reinvention, and, most importantly, a first person testimonial to the reality of oppression.
