Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.     

Chinese American Adolescents’ Perceptions of the Language Brokering Experience as a Sense of Burden and Sense of Efficacy

Children of immigrants who do translations and who interpret for others using their heritage language and English are known as language brokers. Although prior research suggests that children of immigrants’ perceptions of the language brokering experience vary greatly—from feeling a sense of efficacy to feeling a sense of burden—what remains unanswered in the literature is identification of the antecedents and processes that help to explain the varying psychological experience of language brokers. Using data from a two-wave prospective longitudinal study of 256 Chinese American adolescents, the present study tested potential mechanisms that may be responsible for adolescents’ perceptions of the language brokering experience as a sense or burden or sense of efficacy. The results demonstrate that adolescents’ Chinese orientation sets in motion a family process that is linked to variations in the perceptions of adolescents’ language brokering experience. Adolescents who are more Chinese oriented have a stronger sense of familial obligation, and these adolescents are more likely to perceive that they matter to their parents. Adolescents’ perceived sense of mattering to parents, in turn, is associated positively with a sense efficacy, and negatively with a sense of burden as language brokers. Those adolescents who are less Chinese oriented have a weaker sense of familial obligation, and these adolescents are more likely to feel a sense of alienation from their parents. Adolescents’ sense of perceived alienation from parents, in turn, is associated with a sense of burden as language brokers. Implications for developing interventions for children who act as language brokers for their parents are discussed.

Perceptions of Racism and Depressive Symptoms in African American Adolescents: The Role of Perceived Academic and Social Control

Experiences with racism are a common occurrence for African American youth and may result in negative self perceptions relevant for the experience of depressive symptoms. This study examined the longitudinal association between perceptions of racism and depressive symptoms, and whether perceived academic or social control mediated this association, in a community epidemiologically-defined sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling revealed that experiences with racism were associated with low perceived academic control, which in turn was associated with increased depressive symptoms. Findings suggest that experiences with racism can have long lasting effects for African American youth’s depressive symptoms, and highlight the detrimental effects of experiences with racism for perceptions of control in the academic domain. Implications for intervention are discussed.

Enabling collaborative synthesis in multi-partner programmes

Multi-partner consortia have emerged as an important modality for knowledge generation to address complex sustainability challenges. Establishing effective multi-partner consortia involves significant investment. This article shares lessons from the Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA), which aims to support policy and practice for climate change adaptation through a consortium model. Key lessons include the need to facilitate collaborative spaces to build trust and identify common interests, while accepting that this is not a guarantee of success; the importance of programmatic leadership to achieve synthesis; and the value of strategic planning in supporting motivation and alignment between partners.     

Investing in multi-stakeholder dialogue to address natural resource competition and conflict

How can multi-stakeholder dialogue help assess and address the roots of environmental resource competition and conflict? This article summarises the outcomes and lessons from action research in large lake systems in Uganda, Zambia, and Cambodia. Dialogues linking community groups, NGOs and government agencies have reduced local conflict, produced agreements with private investors, and influenced government priorities in ways that respond to the needs of marginalised fishing communities. The article details policy guidance in four areas: building stakeholder commitment, understanding the institutional and governance context, involving local groups in the policy reform process, and embracing adaptability in programme implementation.     

Changing knowledge and perceptions of African indigenous vegetables: the role of community-based nutritional outreach

African indigenous vegetables (AIVs) have potential to sustainably address malnutrition, a growing problem in sub-Saharan Africa. Their consumption is however, limited by poor perceptions and lack of awareness of nutritional benefits. There is limited evidence of the effectiveness of community-focused information dissemination approaches in influencing participants’ perceptions and uptake of innovations in AIVs to address malnutrition. This article aims to fill this knowledge gap, using a case study focusing on pastoral communities in Monduli district in northern Tanzania. Target communities participated in a community-based nutritional outreach facilitated by the Good Seed Initiative (GSI), held at Monduli district hospital in September 2014. The results provide evidence of the achievements of the GSI intervention, and the effectiveness of alternative information dissemination approaches.     

The Malian fertiliser value chain post-subsidy: an analysis of its structure and performance

This article examines the structure of the Malian fertiliser value chain and its performance in the context of the national subsidy programme, drawing on a review of the literature, farm household survey, and interviews with fertiliser suppliers. It finds that participants in the subsidy programme use more fertiliser and have significantly higher yields. The number of wholesalers and retailers has risen, but procurement remains concentrated. Poor fertiliser quality is a recurrent problem. The high cost of the programme raises questions regarding its sustainability. Mixed performance reflects the need for better monitoring and evaluation, and transparency in the programme.     

“Gendering” European security: policy changes,reform coalitions and opposition in the OSCE

The Organisation for Security and Co-operation in Europe (OSCE) has rarely been considered in scholarship on gender and security, even though it was one of the regional security organisations whose gender policy predated the United Nations Security Council’s call for more international attention to issues related to women, peace and security in October 2000. Based on an analysis of official OSCE documents and on semi-structured interviews, we trace the integration of gender issues in the OSCE and explore the rationale behind and the challenges associated with it. We identify two phases of gender policy change in the OSCE and show how the integration of UNSCR 1325 brought about an expansion of OSCE gender policy from an exclusive focus on “soft” security issues towards increased inclusion of gender in the area of “hard” security. Drawing on historical and feminist institutionalism, we argue that reform coalitions were crucial for the policy changes in the OSCE but that they encountered institutional and ideational barriers, which hampered implementation of the gender policy. In light of rising opposition, our analysis warns of a backlash that might jeopardise current achievements.     

Brexit: A Cliff Edge or a Small Bump in the Road?

It is becoming increasingly accepted, not least by the Prime Minister and opposition leadership, that the negotiation of a comprehensive trade relationship with the EU is necessary to prevent the UK economy falling off a ‘cliff edge’. This concern is shaping the UK's strategy towards negotiations with the EU and has provided at least part of the motivation for the UK to consider requesting a transition period to facilitate the Brexit process. But how accurate are these fears? What evidence is there for the existence of a ‘cliff edge’? How disastrous would it be for the UK to revert to trading with the EU on the same basis as most other countries in the world, namely according to World Trade Organisation rules? This article seeks to address these issues and it highlights a number of implications for policy makers which flow from understanding the available evidence a little more clearly.     

Neoliberalism,Nationalism and the Decline of Political Traditions

The three great Western political traditions (conservatism, liberalism, social democracy) incorporate three of the four possible combinations of the core political axes: traditional, unchanging authority versus the challenge of change, and egalitarianism versus inegalitarianism. The fourth possibility—egalitarian conservatism—has appeared in various guises, but has usually become submerged within the right, including its most authoritarian forms. Current xenophobic movements claiming to represent those suffering from excessive change—for example, those involved in the UK 's EU referendum and Donald Trump's victory in the USA —are seeing an apparent resurgence of this neglected tradition. What are its implications for politics in general?
