Identifiable state‐space models: A case study of the Bay of Fundy sea scallop fishery

State‐space models (SSMs) are now popular tools in fisheries science for providing management advice when faced with noisy survey and commercial fishery data. Such models are often fitted within a Bayesian framework requiring both the specification of prior distributions for model parameters and simulation‐based approaches for inference. Here we present a frequentist framework as a viable alternative and recommend using the Laplace approximation with automatic differentiation, as implemented in the R package Template Model Builder, for fast fitting and reliable inference. Additionally we highlight some identifiability issues associated with SSMs that fisheries scientists should be aware of and demonstrate how our modelling strategy surmounts these problems. Using the Bay of Fundy sea scallop fishery we show that our implementation yields more conservative advice than that of the reference model.

Five-Hundred Life-Saving Interventions and Their Cost-Effectiveness

We gathered information on the cost-effectiveness of life-saving interventions in the United States from publicly available economic analyses. "Life-saving interventions" were defined as any behavioral and/or technological strategy that reduces the probability of premature death among a specified target population. We defined cost-effectiveness as the net resource costs of an intervention per year of life saved. To improve the comparability of cost-effectiveness ratios arrived at with diverse methods, we established fixed definitional goals and revised published estimates, when necessary and feasible, to meet these goals. The 587 interventions identified ranged from those that save more resources than they cost, to those costing more than 10 billion dollars per year of life saved. Overall, the median intervention costs $42,000 per life-year saved. The median medical intervention costs $19,000/life-year; injury reduction $48,000/life-year; and toxin control $2,800,000/life-year. Cost/life-year ratios and bibliographic references for more than 500 life-saving interventions are provided.     

Children and the Modern Farming Movement

In the twenty‐first century, a small percentage of U.S. children have ties to family‐based agriculture. Yet with the rise of the modern farming movement that emphasizes local and family‐based production, new spaces may exist for involving children and youth in farming. This article focuses on the social value of children to family‐based agriculture in the contemporary era. Drawing on a qualitative study of families that farm in the capital region of New York—an epicenter for the modern food movement—we consider why families farm, how they involve children in their farms, and how they understand children's contributions. Interviews with 76 adult members of 50 families show children to be central to families' goals; they often rationalize farming as a lifestyle choice undertaken for the benefit of their children. Families also actively involve their own children—and other people's children—in their farms. By documenting the way families talk about children and farming, we shed light on the logic used to incorporate children into modern productive enterprises. The centrality of children, we argue, helps explain the success of the modern food movement and the persistence of family‐based agriculture despite conditions that make it economically difficult to accomplish.     

Making sources of energy: the case of coal (1900–1936)

Recent contributions to a sociological analysis of energy and society focus mostly on its political, economic and technological organization. Yet contrary to other parts of nature, little social scientific attention has been paid to how politics, economics and technology have come to produce and stabilize the concept of energy in the first place and how different natural materials were transformed into “sources of energy.” Drawing from insights of the sociology of comparison, quantification and commensuration, “energy” in this paper is conceived as a “statistical object,” around which a public discourse develops in which comparisons between resources are drawn. Since the beginning of the twentieth century, this discourse has been more and more stabilized by the regular, public production and ever tighter net of elements of comparison, the creation of a highly abstract, potentially quantified point of comparison, and the definition of various criteria tying the compared entities together with more general models and narratives. This theoretical framework is put into practice by an explorative analysis of coal classification in the first quarter of the twentieth century. In this empirical analysis, three fields are identified where coals were “made the same”: engineering, economics and resource statistics. It is shown that the “calorific value” plays an important role for classification in all three fields and, furthermore, constitutes a measure that links coal to other fuels.     

The operation and subversion of gendered war discourses: soldierhood,motherhood and military dissent in the public production of Kimberly Rivera

This article undertakes a discourse analysis of texts concerning a recent high profile case of opposition to war by Kimberly Rivera, a US soldier and a mother of five. Developing on previous research concerning how female soldiers, anti-war women and anti-war soldiers have been made intelligible within understandings of war and gender, the analysis traces the discursive repertoires constituting Rivera as a political subject. The article considers how, when and with what implications for broader discourses of gender and war, and their transformation, the categories of soldierhood and motherhood were invoked to construct and obstruct Rivera as an intelligible dissenting subject. The most common presentation of Rivera centered on her motherhood, understood to be in crisis due to her military role. With motherhood and soldierhood seen to be antithetical this crisis could be “solved” through opposition to war. This limited the extent to which Rivera was intelligible as a “thinking citizen” and reproduced motherhood and soldierhood as stable categories leaving their immanent discourses concerning war and gender untroubled. The article then considers ways in which alternative avenues for transformative interventions could open up if dissenters like Rivera were “written” as other than fundamentally contradictory figures.     

Making connections: Severe mental illness and closeness with other people

Much has been written about social lives of people with severe mental illness (SMI). Before social lives can flourish, however, people with SMI must first get close to other people. We studied this closeness by holding three hour-long focus groups at Fountain House, a community mental health agency in New York City. We found that closeness between two people with SMI is challenging because someone with depression, for example, may have trouble understanding someone with a different disorder (e.g., schizophrenia). Romantically, closeness is also challenging—SMI is hard to explain to partners. In the workplace, closeness is difficult because SMI can alienate co-workers. It could push them away. In mental health programs, we found that closeness has more of a chance to develop (1) during evening and weekend activities; (2) when activities are planned often enough to prevent isolation; and (3) when staff reach out to people before extended absence causes distance.     

Accounting for ethos or programmes for conduct? The brave new world of research ethics committees

This paper examines the operation of power and its consequences arising from the growth of new ethical bureaucracies in universities. We use the UK as a case study to illustrate more general points about the globalised nature and impact of such bureaucratisation. Our focus is on the social sciences as this is where, we argue, the impact is likely to be most marked. The paper is organised in five sections. The first introduces our concerns. Section 2 traces the genealogy of these new regimes of control in the UK. We then problematise the new ethical bureaucracies, making an analysis in terms of the shift in the locus of power away from researchers to becoming centralised in bureaucratic structures. In section 4 we explore some of the ways in which researchers might respond to the changing regimes of ethical control. Finally, we offer considerations of the ways in which ethical governance of research might be differently conducted so as to avoid the adverse consequences of new regimes of control on research practice. Our aim is to provoke debate and thereby contribute to a platform from which to reassert ways to ensure that research is ethical and that do not interfere with the production and consumption of critical social science.     

Gossip as strategy: The management of talk about others on reality TV show 'Big Brother'

In this paper we examine the nature of gossip talk as an activity type in the context of the TV game show 'Big Brother'. Using a detailed analytic approach to the situated nature of gossip sequences, we show how participants in the show manage gossip talk strategically to establish social relationships within the house, as well as to present themselves in a positive way to the viewing (and voting) audience. We argue that there is a contextual double framing for talk in the Big Brother (BB) house which participants are orienting to, both as members of a social group, and as players in a TV game show. The paper thus contributes to existing work on the social function of gossip, as well as exploring its strategic function in this particular interactional context, calling into question the nature of 'natural' discourse.
