The Independent Localisations of Interaction and Learning in the Repeated Prisoner's Dilemma

The results of a series of computer simulations demonstrate how the introduction of separate spatial dimensions for agent interaction and learning respectively affects the possibility of cooperation evolving in the repeated prisoner's dilemma played by populations of boundedly-rational agents. In particular, the localisation of learning promotes the emergence of cooperative behaviour, while the localisation of interaction has an ambiguous effect on it.     

A Longer View: Is Industrial Metabolism Really the Problem?

Seen from the long perspective of recent historical research on Europe's pre-industrial millennia, large-scale human destruction of natural environments and ecological relationships evidently pre-dates industrial metabolism. If so, the limited view of the most recent centuries arguably fails to encompass the depth of experience required to understand current problems or therefore to formulate successful remedies or responses to human violations of carrying capacity. The longer past reveals some cultural mechanisms to counteract the pressures of human wants and needs. Comparative research is urged on long-term ecological outcomes in other great pre-industrial civilizations.     

Internal corporate governance mechanisms as drivers of firm value: panel data evidence for Chilean firms

The paper analyses to what extent ownership structure, capital structure, and dividend policy as corporate governance mechanisms drive the firm value. From a data panel of publicly quoted Chilean firms for the years 2002–2010, we find that there is an inverse U-shaped relationship between ownership concentration and firm value. The positive slope is supported by the supervision hypothesis; whilst the negative relation between ownership concentration and firm value is supported by the expropriation hypothesis. We also find that there is a positive impact of both leverage and the dividend pay-out on the firm value. In this case, these two mechanisms reduce the free cash flows which otherwise might be used opportunistically by managers in their own interests (free rider problem). Contrary to the previous empirical literature in Chile, it is found that the mere fact that a firm is affiliated to a business group/conglomerate impacts positively its value. This positive effect is basically driven by the development of intragroup capital markets, and the governance imposed by the rules of the conglomerate.     

Environmental determinism as Orientalism: The geo-political ecology of crisis in the Middle East

From ‘Resource Curse’ to ‘Climate Conflict’, more and more analyses of the current crisis in the Middle East start their reasoning from geo-physical or natural conditions as determinants of social life. Paradoxically, despite its resource riches giving rise to conflict, the region's ecology is portrayed as fragile, alien and hostile. This imperial oriental imagination, assumes that a scarce nature is mismanaged by societies and states overall incapable of negotiating modernity. This precarious, crisis driven environment is now pushed to the edge by the effects of climate change with looming desertification and weather extremes and a scramble for shrinking oil reserves threatening to make the region all but inhabitable. This article suggests that this environmental oriental determinism in Middle East can be overcome by entering political ecology into the register of historical sociological analysis. Re-socialising and historicising nature-society relations avoids reifying the Cartesian nature/society divide, offering historical sociology a better toolkit to navigate the current crisis. Vice-versa, it argues that political ecology can benefit from recognising the role of geopolitical relations in the social reproduction nature.     

The importance of clinician courtroom testimony for children exposed to domestic violence

Children exposed to domestic violence account for as many as a third of all children in the United States. Many of these children will seek mental health treatment for symptoms of trauma. The clinicians who provide their treatment are often called as witnesses in family law proceedings, especially child protection and custody cases. Clinicians are often anxious when they receive subpoenas to testify and prefer to avoid testimony. Training about court proceedings, subpoenas and how to prepare for testimony would be beneficial for clinicians and will help clinicians be more confident in the courtroom. Additionally, becoming designated as expert witnesses can only help mental health clinicians provide a greater understanding of the issues encountered by children experiencing domestic violence, and these clinicians can provide recommendations that will take into account child safety without exacerbating trauma symptoms.     

The Taste of the Eye and the Sight of the Tongue: the Relations between Sight and Taste in Early Modern Europe

This article examines the articulation between the senses of taste and sight through the representations of their organs, the tongue and the eye, in early modern Europe. The relationship between taste and sight first brings to mind gastronomical aesthetics, and the part played by the eye in the relish of beautifully presented dishes. The first part of this article is therefore devoted to exploring the taste of the eye (or the foretaste of sight) and highlights the harmony of taste and sight in early modern cuisine. However, the forms of reciprocity between taste and sight cannot be reduced to the sole figure of culinary aesthetics, which tends to blur the other multiple modalities that this sensorial association could reveal. The second part, the sight of the tongue (or the invisibility of taste), thus examines more complex layers of the relationship between the sense of sight and the taste organ, through a study of the representations of the tongue and of the gaping mouth in early modern visual culture. Drawing on early modern textual and iconographic resources and exploring: cookbooks; physiognomic works; conduct books; and also engravings and paintings related to the culinary arts, the seven deadly sins, and representations of madness and the fool in early modern visual culture, this essay argues that examining the representations of the sense organs is a suggestive way to explore the relationship between the senses.     

Comparing Observed and Unobserved Components of Childhood: Evidence From Finnish Register Data on Midlife Mortality From Siblings and Their Parents

In this study, we argue that the long arm of childhood that determines adult mortality should be thought of as comprising an observed part and its unobserved counterpart, reflecting the observed socioeconomic position of individuals and their parents and unobserved factors shared within a family. Our estimates of the observed and unobserved parts of the long arm of childhood are based on family-level variance in a survival analytic regression model, using siblings nested within families as the units of analysis. The study uses a sample of Finnish siblings born between 1936 and 1950 obtained from Finnish census data. Individuals are followed from ages 35 to 72. To explain familial influence on mortality, we use demographic background factors, the socioeconomic position of the parents, and the individuals’ own socioeconomic position at age 35 as predictors of all-cause and cause-specific mortality. The observed part—demographic and socioeconomic factors, including region; number of siblings; native language; parents’ education and occupation; and individuals’ income, occupation, tenancy status, and education—accounts for between 10 % and 25 % of the total familial influence on mortality. The larger part of the influence of the family on mortality is not explained by observed individual and parental socioeconomic position or demographic background and thus remains an unobserved component of the arm of childhood. This component highlights the need to investigate the influence of childhood circumstances on adult mortality in a comprehensive framework, including demographic, social, behavioral, and genetic information from the family of origin.     

Musculoskeletal problems in bricklayers as a function of length of employment: The role of secondary selection by low-back pain

Abstract

Low-back problems that are caused by heavy physical work should increase with the length of employment. In a cross-sectional study 195 bricklayers were interviewed and subjected to a medical examination concerned with complaints and functional impairments of the musculoskeletal systems of different body regions (neck/shoulder, arms/hands, back, hip/legs/feet). Summary variables for complaints and impairments indicated an increase with increasing age. Contrary to expectation, in pairs of bricklayers of the same age, but different length of employment, a general decline of complaints and impairments with longer employment was observed. This finding suggested a healthy worker effect. In a follow-up the turnover rate among 190 of the 195 bricklayers of the original study was determined. Bricklayers who had quit the job had a higher incidence of low-back troubles before leaving than bricklayers who had stayed in the job; the relation between turnover and low-back problems was limited to bricklayers older than about 40 years.
