Simulating Male Selfish Strategy in Reproduction Dispute

We introduce into the Penna Model for biological ageing one of the possible male mechanisms used to maximize the ability of their sperm to compete with sperm from other males. Such a selfish mechanism increases the male reproduction success but may decrease the survival probability of the whole female population, depending on how it acts. We also find a dynamic phase transition induced by the existence of an absorbing state where no selfish males survive.Comment: 7 pages, latex including 2 eps figure

‘We kind of try to merge our own experience with the objectivity of the criteria’: The role of connoisseurship and tacit practice in undergraduate fine art assessment

This article explores connoisseurship in the context of fine art undergraduate assessment practice. I interviewed twelve fine art lecturers in order to explore and unpack the concept of connoisseurship in relation to subjectivity, objectivity and tacit practice. Building on the work of Bourdieu (1973, 1977, 1986) and Shay (2003, 2005), both of whom problematize the view that subjectivity and objectivity are binary opposites, my research illustrates the ways that connoisseurship is underpinned by informed professional judgements located in communities of practice. Within this particular conception of connoisseurship, the lecturers’ expertise is co-constituted in communities of assessors through participation and engagement. Standards reside in communities of practice

Advocating co-productive engagement with marginalised people: a specific perspective on and by survivors of childhood sexual abuse

Co-production is gaining ground as a key dimension of public policy reform across the globe.This paper argues in favour of social welfare shaped by the principles of co-production and suggests that the promotion of democratic relationships is more likely to enable the agency and recovery of victim-survivors of childhood sexual abuse. The paper, based on an autoethnographical approach, is likely to be of relevance to social care practitioners who work with a range of marginalised people, particularly in liberal states that promote organisational cultures shaped disproportionately by risk. Cultures of risk, it is argued, promote power balances and ‘othering’, arguably an institutional perpetuation of the original abuse. Co-production, on the other hand, has the potential to legitimise expertise by experience, enabling victim-survivors to be reinstated as citizens with associated rights of participation. The paper subsequently draws out some of the benefits of co-production for practitioners whose professional engagement may be stifled. We suggest that co-production potentially points towards practice based on the valuing of expertise by experience and social solidarity
