Managing the Black Sea Anchovy Fishery with Nutrient Enrichment and a Biological Invader
Many marine systems are subject to high nutrient loadings together with invasions by exotic species. Devising appropriate management responses is an increasing concern and one that has received relatively little attention from researchers. This paper considers the Black Sea anchovy fishery, which has benefited from the relaxation of a nutrient constraint, but has suffered from competition and predation by an invading comb-jelly (Mnemiopsis leidyi). We examine alternative hypotheses about the mechanism triggering outbreaks of the invader (sea temperatures versus nutrients), and the severity of these outbreaks, to see whether a constant escapement policy might be optimal for this fishery. If nutrient levels serve as the triggering mechanism, we argue a mixed blessing effect may be present, so that the effects of nutrient abatement for the anchovy fishery are uncertain. We specify our model empirically and show that a constant escapement policy would be viable under a scenario of reduced impacts from outbreaks of the invader and that nutrient abatement could be beneficial if nutrients trigger outbreaks.Mnemiopsis leidyi, nutrient abatement, stochastic bioeconomic model, biological invasion, Resource /Energy Economics and Policy, O3, O41, Q2, Q20, Q22,
How bucket lists help the terminally ill β and those around them
First paragraph: Buckets lists – inventories of things to do before you die – are often developed by people who know they have little time left. It seems like a good idea. But are they really beneficial, or can they cause harm? And is it really useful to generate lists that may – either due to expense or illness – be perceived as unrealistic?

Experiences of restorative justice in settings with children and young people: The accounts of professionals and young people.
Paper 1:
Examining the views of restorative practitioners about the effects of their professional practices.
Abstract
The Youth Justice Board and the Department for Education share the common goal of reducing offending and harmful behaviour in children and young people (Ministry of Justice, 2010; DfE, 2011). In both sectors, evidence for the effectiveness of practices based upon the principles of restorative justice (RJ) is mounting, yet there is a distinct lack of theoretical clarity regarding the psychological mechanisms through which such practices work. Moreover, the voice of RJ practitioners is not found in current theoretical propositions. In this paper, eight RJ practitioners, from a mixture of school and youth justice backgrounds, are interviewed about their professional practices. Interview transcripts are thematically analysed in an inductive manner, according to the guidelines set out by Braun & Clarke (2006). Analysis is interpreted in terms of responsive regulation (Braithwaite, 2002; Morrison, 2003), the social learning perspective of Macready (2009) and in terms of cognitive dissonance theory (Festinger, 1957). It is suggested that RJ-based practices, according to the views of professionals, are effective because a) they respond to harm flexibly and after the incident, b) they engage young people in a process of learning social responsibility and c) they provide young people with ways of reducing cognitive dissonance based upon acknowledging and repairing harm, rather than through blaming and denying responsibility. Paper 2:
Examining the views of young people about their experiences of restorative justice-based practices.
Abstract
The Youth Justice Board and the Department for Education share the common goal of reducing offending and harmful behaviour in children and young people (Ministry of Justice, 2010; DfE, 2011). In both sectors, evidence for the effectiveness of practices based upon the principles of restorative justice (RJ) is mounting, yet there is a distinct lack of theoretical clarity regarding the psychological mechanisms through which such practices work. Whilst the voice of young people can be heard in the literature, these have come primarily through surveys and other closed-question response formats. Thus, there is a lack of an in-depth characterisation of young peopleβs experiences of RJ. In this paper, six young people are interviewed about their experiences of RJ-based practices. Interview transcripts are thematically analysed in an inductive manner, according to the guidelines set out by Braun & Clarke (2006). Analysis is interpreted in terms of Bartonβs (2000) Empowerment Model of Restorative Justice (EMRJ) and in terms of responsive regulation (Braithwaite, 2002; Morrison, 2003). It is suggested that RJ-based practices, according to the views of young people, are effective because a) they empower young people in the process of responding to harm and b) they involve responding to harm flexibly and after the incident, providing emotional support and enabling all stakeholders to be open and honest. The implications of both these findings and those from paper 1 are discussed in the context of Aug 2011 riots.Children's Workforce Development Counci
