The impact of social heterogeneity and commodity price shocks on civil conflicts

Do exogenous economic shocks promote civil conflicts directly? Do they affect all the societies alike? The current approach presents a large sample panel data evidence not only on the effect of commodity export price shocks on conflict incidence, rather than onsets, but also on the joint impact of both ethnic and religious polarization and fractionalization on political instability. In this regard, we find out that in ethnically polarized societies, the commodity export price shocks increase violence. Nonetheless, in ethnically and religiously fractionalized societies (as well as religiously polarized), the effect of commodity export price shocks on civil conflicts depends on the type of income shocks and category of commodity. These findings contribute to the existing literature by illuminating the compound effect of both income shocks and social diversity on intrastate conflicts.     

Key decisions in child protection services in cases of domestic violence: maintaining services and out‐of‐home placement

This paper looks at the response of the child protection services (CPS) system in cases where exposure to domestic violence occurs alone or together with abuse or neglect, focusing on the factors involved in decisions to maintain the case open for ongoing services or remove children from the home. The study is based on an analysis of clinical and administrative data from the files on children reported to a CPS agency in Montreal, Canada. A total of 1 071 substantiated reports were documented, including 337 cases of co‐occurrence (32%). Analysis of the data shows that domestic violence does not by itself constitute a factor liable to lead to more intrusive intervention. The CPS response appears to be influenced more by the existence of other forms of maltreatment and risk factors. Additionally, while domestic violence may be associated with more severe individual and family problems, it does not influence the decision to keep the case open because the child still need services. The lack of any connection between domestic violence and this decision is a cause for concern, as results indicate that such families need help. Knowing how to respond to their needs therefore remains a major challenge.     

Partisan Cleavages in the Importance of Citizenship Rights and Responsibilities*

Objective. Research indicates partisan polarization on a number of social and moral attitudes. However, it is unclear whether a similar polarization can be found regarding citizenship norms, a question we investigate. Methods. Using 2004 GSS data, we examine regression results analyzing citizens' beliefs about a wide range of citizenship duties and rights based on their partisan identity. Results. Democrats and Republicans differ little in regard to many key rights and duties, such as the importance of voting and the right to equal treatment by the government. However, compared to Republicans, Democrats attach more importance to social duties and rights for political participation and for minority groups. Independents are most distinctive, placing much less importance on political duties and social rights of equality and an adequate standard of living, particularly in comparison to Democrats. Conclusion. The majority of Americans share a common set of citizenship norms. Yet, some differences occur along partisan lines, and Independents hold weaker citizenship norms compared to Republicans and Democrats.     

A decision-theoretical view of default priors

In this article, we outline a simple and intuitively appealing procedure to derive default priors. The main idea is to regard the choice of such a prior as a formal Bayesian decision problem. We also discuss Jeffreys prior and more generally the reference prior of Bernardo (J R Stat Soc B 41:113–147, 1979) from this standpoint.     

Global sensitivity analysis of stochastic computer models with joint metamodels

The global sensitivity analysis method used to quantify the influence of uncertain input variables on the variability in numerical model responses has already been applied to deterministic computer codes; deterministic means here that the same set of input variables always gives the same output value. This paper proposes a global sensitivity analysis methodology for stochastic computer codes, for which the result of each code run is itself random. The framework of the joint modeling of the mean and dispersion of heteroscedastic data is used. To deal with the complexity of computer experiment outputs, nonparametric joint models are discussed and a new Gaussian process-based joint model is proposed. The relevance of these models is analyzed based upon two case studies. Results show that the joint modeling approach yields accurate sensitivity index estimators even when heteroscedasticity is strong.     

Competitive Strategies and Firm Performance: a Comparative Analysis of Pure,Hybrid and ‘Stuck‐in‐the‐middle’ Strategies in Spanish Firms

The purpose of this study was to examine the viability of hybrid competitive strategies, which combine differentiation and cost elements, and their impact on organizational performance in comparison to pure strategies and ‘stuck‐in‐the‐middle’ combinations. Previous studies have focused above all on US data. The analysis carried out in this paper has centred on a multisectorial sample of 164 Spanish firms. The findings show that a large number of the organizations use different types of hybrid strategies and also that such strategies tend to be associated with higher levels of firm performance, particularly those strategies which place emphasis on a greater number of strategic dimensions, and specifically on innovation differentiation.     

Baby boomers and their entourage

The post-war generation of baby boomers has witnessed major transformations in family life as well as being at the vanguard of them. A study undertaken in Paris and London in 2006 among 90 individuals born between 1945 and 1954 reveals, however, strong relationships with ageing parents and adult children. Family groups based on local or dispersed entourages, with regular contact and the exchange of support, are clearly identified. Other configurations include families where affective ties persist but contact between the baby boomers and their entourage is less frequent. Few baby boomers have replaced family members with friends or remain socially isolated. These results show that the rise of individualism associated with the baby boomers has not weakened inter-generational ties, although tensions exist between the demands of family solidarity and individual projects.     

Real-life closeness of social media contacts and depressive symptoms among university students

ABSTRACT

Objective: To examine the association between degree of real-life closeness of social media (SM) contacts and depressive symptoms. Participants: Students ages 18–30 (N = 1124) were recruited in August 2016. Methods: Participants completed an online survey assessing SM use and depression. We used multivariable logistic regression to assess associations between real-life closeness of SM contacts and depressive symptoms. Results: After controlling for covariates, each 10% increase in the proportion of SM friends with whom participants had no face-to-face relationship was associated with a 9% increase in odds of depressive symptoms (AOR = 1.09; 95% CI = 1.05–1.13). However, each 10% increase in the proportion of SM friends with whom participants had a close face-to-face relationship was associated with a 7% decrease in depressive symptoms (AOR = 0.93; 95% CI = 0.89–0.97). Conclusions: Having no in-person relationship with SM contacts is associated with increased depressive symptoms; however, having close in-person relationships with SM contacts is associated with decreased depressive symptoms.     

Elder Abuse and Neglect in African American Families: Informing Practice Based on Ecological and Cultural Frameworks

Despite the rapid growth of the elderly African American population in the U.S., elder abuse and neglect in African American families continue to be underdeveloped areas of study. This article presents an ecological and culturally informed framework for the study of elder abuse in African American populations. The model was developed based on Bronfenbrenner's Human Ecological Theory. The model identifies risk factors associated with different systems that have an influence on the lives of African American families. Cultural protective factors also are identified in the model. The model is intended to provide an understanding of elder abuse and neglect in African American families by considering the influence of contextual factors such as the legacy of slavery, social exclusion, and structural segregation and racism. Specific suggestions for practice are proposed according to cultural strengths of African American communities as well as the ecological premises of the model.     

Can ‘art Professions’ Be Bourdieuean Fields Of Cultural Production? The Case Of The Architecture Competition

The difference between ‘artistic and literary fields’ and universes such as architecture usually recognized as ‘art professions’ but which enjoy a far lesser ‘degree of autonomy’ than such fields seemingly constitutes an obstacle to the broader application of the notion of a ‘field of cultural production’ sought by Bourdieu in his Rules of Art. The author of this paper overcomes this obstacle by employing his notion of the ‘field effect’, with the architecture competition serving as the test case. Following Bourdieu, the author replaces the notion of profession with that of the field, for the former is a representation fostered by professional groups themselves. Architecture is a field, but, because architects require clients to construct and realize their works, one unlike the artistic and literary fields, which are markets of symbolic goods where ‘distinterest’ reigns and an autonomy unthinkable elsewhere is enjoyed. However, much like artists and unlike any other ‘professionals’, architects enter competitions, suggesting that this practice is an analytically relevant indicator of the field effect. After defining several of the elements of Bourdieu's relational conceptual matrix (field, illusio, collusion, doxa and space of possibles) and demonstrating that the Baptistery competition in Florence (1401) conforms to Bourdieu's historical beginning point for the process of 'autonomization' of artistic production, I examine a number of competitions from 1401 to 1989 (Berlin Jewish Museum) along with the general properties of competitions (structure and organization, publication and exhibition of results, competitors' economically irrational behaviour, practices of designers and jurors and the associated universe of beliefs), analysing them as those of an artistic field. It is concluded that when architects enter competitions, architecture, at least provisionally resembles an artistic field, for there is a field effect shown by a high degree autonomy, disinterest and the creation of an upside-down world.
