An efficient statistical procedure for interpreting DNA single locus profiling data in crime cases.

This paper describes a simplified approach to calculating the Bayesian likelihood ratio for the case where two DNA single locus profiles are to be compared. It explains how the calculation allows for band shift and also for the variation in precision with molecular weight. A simple basic theory section explains the principles of the analysis but more detailed explanations are given in an advanced theory section. Experiments on substantial data collections are described which demonstrate the robustness of the method.     

An investigation of the feasibility of inferring ethnic origin from DNA profiles.

A small experiment is described which uses databases of Afro-Caribbeans and Caucasians to establish the quality of information that might be given to an investigator about the ethnic group of the donor of an unknown crime stain. The results show that the technique can provide qualified indications, but categoric conclusions are not, in general, feasible. An appraisal is given of the technique within the operational context.     

Social Innovation and Crisis in the Third Sector in Spain. Results,Challenges and Limitations of ‘Civic Crowdfunding’

Based on the evolution and institutional transformation of the Welfare State and its relationship with the Third Sector of Social Action, the present article describes and analyzes the aspects of the financial crisis and resources that the sector is currently suffering. In regards of these structural transformations the evolution, characteristics, limitations and opportunities offered by ‘civic crowdfunding’ in Spain between the years 2011 and 2015 as an innovative social practice for the increase of the own funding between the entities of the Third Sector of Social Action and the changes that must be experienced by the sector in order to optimize and improve its self-funding ratios through this mechanism are examined. The high index of success of financing social projects (96.5%) through this tool, and the annual growth during the analyzed period shows the potential of civic crowdfuding. On the other hand, the small size of the bankable projects (95.2% less than 10,000 euros), as well as the low total amount collected (2,665,384 euros) indicates that civic crowdfunding is still an insufficient mechanism to mitigate the severe public resource cuts suffered by the entities of the Third Sector of Social Action and also to bring these entities closer to the objective of self-financing. Finally, we formulated a series of recommendations aimed at improving the self-financing ratios of the Third Sector of Social Action, including a more efficient and cooperative use of civic crowdfunding.     

Formal and Informal Seed Systems in Kenya: Supporting Indigenous Vegetable Seed Quality

Indigenous vegetables play an important role in Kenyan food security, but production is limited by poor seed quality. Traditionally, seeds have been traded through informal networks, but a new formal seed sector is emerging. This study assessed the relative potential for formal or informal seed systems to meet the need for high-quality indigenous vegetable seed. By evaluating determinants of farmers’ seed purchasing behaviour, we conclude that informal seed systems have greater potential to meet this need and should be strengthened. This study suggests that policy-makers should use context-specific data to guide decisions on seed policy.     

Media and subnational democracy: the case of Bahia,Brazil

It is a well-known fact that the transition to and consolidation of democracy in Latin America have been problematic, especially at the subnational level. It is also commonplace to equate an independent media system with a strong democracy. While each of these fields has witnessed important developments in the last decade or so, there have been sparse attempts to draw the theoretical links between them. In this article, I argue that there are important insights to be gained from such an endeavour. Bahia, a state in north-eastern Brazil, is an ideal case study to bring these perspectives together. This study offers fresh insights on state–society relations at the subnational level and on the contemporary interaction between the public and the private spheres in Latin America. Last but not least, it will also provide a better grasp on the challenges democratization faces at the subnational level and the role of the media in them.     

Correlates of Childhood vs. Adolescence Internalizing Symptomatology from Infancy to Young Adulthood

In light of its associations with child and adolescent health and well-being, there remains a need to better understand the etiological underpinnings and developmental course of internalizing symptomatology in children and adolescents. This study leveraged intensive longitudinal data (N?=?959; 49.6?% females) to test the hypothesis that internalizing symptoms in childhood may be driven more strongly by family experiences whereas internalizing symptoms in adolescence may derive more uniquely from familial loading for affective disorders (i.e., maternal depression). We evaluated the relative contributions of (a) family experiences (b) maternal depression, and (c) peer influences in testing this hypothesis. The results indicated that family predictors were more strongly correlated with childhood (relative to adolescent) internalizing symptoms. In contrast to previous findings, maternal depression also exhibited stronger associations with childhood internalizing symptoms. Although often overlooked in theories concerning potential differential origins of childhood vs. adolescent internalizing symptomatology, peer experiences explained unique variation in both childhood and adolescent internalizing problems.     

Food sovereignty and new peasantries: on re-peasantization and counter-hegemonic contestations in the Basque territory

This paper contributes to debates about the potential of re-peasantization and its contribution to food sovereignty with a case study from the global North, where such questions are relatively under-studied. I examine how Euskal Herriko Nekazarien Elkartasuna (EHNE)-Bizkaia, a Vía Campesina member organization from the Basque Country (Spain), advances food sovereignty through re-peasantization. I also analyze the motivations of new peasants engaged in agroecology, their understandings of food sovereignty, and the challenges that they face. Using a Gramscian political ecology framework, I argue that whereas re-peasantization contributes to a shift from corporatist to counter-hegemonic struggles, the political-economic and biophysical contexts structure agroecological production in ways that limit the extent to which new peasantries can become ‘agents of their own history’. I conclude that closer attention to peasants’ messy practices of making a living is needed to address questions of political agency.     

Preventing violence through hip hop: an evolutionary perspective

ABSTRACT

For decades Hip Hop cultural practices have been disparaged for allegedly inciting and being responsible for the eruption of urban violence. This assumption, likely built upon pre-existing biases regarding the street culture and ethnic minorities where Hip Hop emerged, ignored how some of the genre’s main elements – particularly freestyle rap, breakin’ or breakdancing and graffiti tagging – initially served the purpose of providing at-risk youths with real alternatives to direct physical violence in their day-to-day lives, and continue do so today. It has also ignored broader analogies with other cross-cultural and cross-species manifestations of similar practices that have served for millennia as effective mechanisms for reducing the likelihood of potentially lethal violence. By presenting these manifestations – namely song dueling and mark making – in comparative terms with Hip Hop’s freestyle song and dance battles and tagging territorial contests, this article seeks to highlight the relevance and potential of Hip Hop for preventing violence while also suggesting a common evolutionary backdrop within the context of strategies aimed at minimizing intraspecific aggression.     

Trust and Reciprocity in the Aftermath of Natural Disasters

Abstract

Beyond all the material and economic losses that natural disasters produce, post-disaster environments can alter the social capital of a community by affecting social norms, attitudes, and people’s behaviour. To analyse this issue, we empirically investigate the effect that the aftermath of a disaster can have on trust and reciprocity of people within communities. We do this by comparing outcomes of trust games conducted in earthquake-affected and non-affected rural villages one year after the 2010 Chilean earthquake. Our findings show that while trust levels do not differ across cases, reciprocity is lower in earthquake-affected areas.
