Technology selection in the absence of standardised materials and processes: a survey in the UK composite materials supply chain

Composite materials is an industry where technology selection has major consequences as there is not a standard manufacturing process, nor are there standardised materials with defined or proscribed properties for companies to select as multiple solutions are technically viable. This research aims to identify key factors for manufacturing technology selection in the UK composite materials supply chain. Literature review and managers’ opinions were used to identify 18 factors affecting manufacturing technology selection. This was followed by a survey comprising the multi-tier supply chain of the composite materials industry. The results of the survey show ‘on time deliveries/service level to customers’, ‘improve quality’ and ‘reduce cycle time’ received the highest average ratings. In this study a correlation analysis was performed to identify the underlying dependencies between the factors investigated. The identification and use of underlying dependencies rather than highest average provided a more comprehensive picture of the factors that affect technology selection in the composite materials industry. For this study, experts in composite materials were asked to comment on the findings of the survey and their value to the industry. The results presented may assist companies in the composite materials industry with technology selection decision-making processes.     

Lights and shadows on sustainability rating scoring

Many organizations currently publish sustainability ratings that quantify the sustainability of firms by aggregating scores. These organizations analyze companies in economic, social, environmental and corporate governance terms. However, some of these scores are associated with problems of how positive and negative assessments are offset. This work proposes a methodology for using fuzzy logic in the design of a comprehensive sustainability rating for firms. This technique for measuring sustainability addresses the complexity of the concept and enables the incorporation of expert knowledge into the system of assessment. This approach is applied to organizational information taken from the 2008 Accountability Rating and corrects one of the weaknesses revealed by methodologies based on the aggregation of scores—the offset effect—enabling decision-maker to manage it. This is considered an important research topic because of the growth of social responsible financial markets, and the fact that investors are demanding more accurate information.     

WORKERS,WARRIORS, AND CRIMINALS: SOCIAL CONFLICT IN GENERAL EQUILIBRIUM

We incorporate appropriation activities (social conflict) into canonical models of trade and study how economic shocks and policies affect the intensity of conflict. We show that not all shocks that could make society richer reduce conflict: positive shocks to labor‐intensive industries diminish conflict, while positive shocks to capital‐intensive industries increase it. The key requirement is that conflict activities be more labor intensive than the economy as this determines how shocks affect the returns and costs of conflict. Our theory is consistent with several observed patterns of conflict and implies that empirical work should take into account the relative factor intensities of the productive and conflict sectors in each country. Incorporating appropriation into a canonic general equilibrium model affects what policies may be deemed desirable: in order to reduce conflict and generate Pareto‐improvements policy must be distortionary, while reforms that appear efficiency‐enhancing under the unrealistic assumption of perfect property rights may backfire. This offers one explanation for why reforms based on traditional models without appropriation may be delayed and become unpopular when implemented, and why societies may sympathize with seemingly inefficient redistribution.     

Social work education in Spain: evaluation and challenges for a new generation of social workers

ABSTRACT

The European social integration model was built on two main pillars: employment and access to the welfare state. European social work education was mainly oriented to training professionals in order to promote this inclusion through case management and the provision of benefits. This influence was very intense in the curricular content of Spanish social work programs. The new social risks and the European convergence in higher education have promoted curricular changes, but is it enough?. This paper aims to identify the content and limits of current social work education in Spain. To this end, a comparative analysis of social work education in public universities of Spain was performed. This information has been contrasted with professionals, teachers and social work students. The results evidence the gap of these contents with the real professional needs. This paper proposes several alternatives and approaches in new intergenerational methodologies and technological tools to train a new generation of social workers     

A Universal QQ-Plot for Continuous Non-homogeneous Populations

This article presents a universal quantile-quantile (QQ) plot that may be used to assess the fit of a family of absolutely continuous distribution functions in a possibly non-homogeneous population. This plot is more general than probability plotting papers because it may be used for distributions having more than two parameters. It is also more general than standard quantile-quantile plots because it may be used for families of not-necessarily identical distributions. In particular, the universal QQ plot may be used in the context of non-homogeneous Poisson processes, generalized linear models, and other general models.     

Multifamily therapy in the community mental health network: A pragmatic randomized and controlled study

Multifamily therapy (MFT) is a psychotherapeutic group intervention for patients with severe mental disorders (SMDs) and their families. The present study is a multicenter, randomized, and controlled trial that analyzes the benefit of MFT during outpatient treatment. The recruited patients were randomly assigned to the experimental group (n = 26), which received 24 MFT sessions in addition to their treatment as usual (TAU), or to the control group (n = 29), which received only TAU (individual and family sessions). Six months after the inclusion in the MFT, the experimental group showed a significant decrease in number of visits to the psychiatric emergency services, number of psychiatric admissions, and the days of admission. The need for hospital care 6 months after recruitment was also lower in the experimental group compared to the control group. These results suggest that the implementation of MFT during outpatient treatment facilitates community management of people diagnosed with mental health problems.     

Why die for my sibling? The positive association between identity fusion and imagined loss with endorsement of self-sacrifice / ¿Por qué morir por un hermano? La asociación positiva entre la fusión de identidad y la pérdida imaginada con la disposición al autosacrificio

Abstract

Identity fusion — a visceral feeling of connection with a group — is a powerful predictor of willingness to engage in extreme pro-group behaviour. Here we propose that identity fusion also reinforces willingness to fight and die for one’s siblings, and we explore one of the underlying mechanisms producing this effect. We additionally controlled for a powerful predictor of family investment, perceived psychological similarity with the sibling. Our study shows that fusion with a sibling, but not perceived similarity, is positively associated with willingness to fight and die for the sibling. This relation is mediated by the imagined personal consequences of losing one’s sibling. This research extends previous work on fusion with groups to pairs of individuals and identifies a new mediator of the effect of fusion on willingness to fight and die for others. Overall, these results suggest that identity fusion might contribute towards explaining self-sacrifice among genetically related individuals as predicted by the theory of kin selection.     

Inequality in the “Cradle of Liberty”: Race/Ethnicity and Wealth in Greater Boston

New data collected for the Boston Metropolitan Statistical Area provide detailed information on financial assets that allow analysis to extend beyond the traditional black–white divide. Targeting US-born blacks, Caribbean blacks, Puerto Ricans, Dominicans, and other Hispanics, findings from the National Asset Scorecard for Communities of Color survey underscore the large racial and ethnic disparities in financial wealth, even after controlling for demographic and socioeconomic status. Further, some notable differences between Boston’s communities of color highlight the importance of detailed analyses for research on the racial wealth gap. In particular, among non-white communities Dominicans report comparatively low asset and high debt amounts, while Caribbean blacks report relatively higher levels of wealth. Altogether, these findings point to the need for wealth building opportunities in communities of color and further investigation of the causes and consequences of financial disparities between groups of color disaggregated by specific ancestral origin.
