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.     

俄罗斯问题的西方表述——关于欧美俄苏研究导论

在国际学术界和国际政治领域,俄罗斯问题是一个很复杂的概念.之所以如此,远不只是俄国本身的文明结构之复杂性所致,更有西方的独特表述之原因.影响西方对俄罗斯问题表述的,是因为西方自身的欧洲中心论、欧美所建构的"西方"概念及其在国际和俄国所产生的反应、对俄罗斯问题进行斯拉夫-俄国-苏联学研究等,这些原因从不同方面促成了西方对俄罗斯问题的认知和判断远不同于俄国,既时有谬误,又始终有着主体意识、独特发现.     

印俄战略伙伴关系的新发展

印俄战略伙伴关系是冷战时期印苏特殊关系的继承和演进。进入21世纪以后,随着俄罗斯的复兴和印度的崛起,双方重新审视对方在各自战略棋盘上的分量,决定建立"战略伙伴关系",加强在政治、经济、军事、科技、能源等领域的合作。由于俄罗斯与中国的"战略协作伙伴关系"不断深化,印度与中国"面向和平与繁荣的战略伙伴关系"正在推进,印俄战略伙伴关系对于中国具有某种积极意义。尽管印俄对中国的态度有一定区别,但是印俄战略伙伴关系对中国的良性作用值得肯定。

欧盟反倾销调查不同阶段关于产业损害认定的法律标准及证据规则

根据欧盟现有的反倾销立法及其实践,欧盟反倾销产业损害认定能否成立大致可以分成立案审查阶段、初裁前调查阶段、终裁前后续调查阶段和复审阶段等四个阶段.这四个阶段中,欧盟反倾销调查机构关于损害认定的法律标准的侧重点各不相同,而且在利害关系方证据材料的要求方面各具不同特点.欧盟产业损害调查各阶段法律标准和证据规则侧重点不同的做法并没有违反WTO《反倾销协定》之原则和精神,欧盟反倾销调查各阶段产业损害认定采用不同标准的做法值得我国借鉴.     

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.
