Preparing NATO for the Future – Operating in an Increasingly Contested Environment

The global proliferation of precision-strike systems may be challenging the foundations of Western military-technological supremacy. Relatedly, the development of so-called Anti-Access and Area Denial (A2/AD) capabilities across the globe threatens to complicate Western freedom of military movement and access, and could give way to a more contested military-strategic environment. The twin challenges of precision-strike proliferation and A2/AD strongly impact NATO’s agenda, which revolves around strengthening deterrence and defence in Eastern Europe, and addressing the different threats emanating from the so-called Southern European neighbourhood. In order to address or mitigate such challenges, the Alliance needs to produce operational concepts and capabilities able to deliver deterrence and expeditionary warfare in a maturing precision-strike environment, one characterised by the emergence of A2/AD capabilities.     

How Do Developers Respond to Land Use Regulations? An Analysis of New Housing in Los Angeles

There is strong evidence that land use regulations constrain housing production. We know less about how real estate developers respond to specific zoning provisions. I compare the characteristics of new multifamily housing with baseline land use regulations in two sets of rail station areas in Los Angeles. I supplement this building-scale analysis with expert interviews. I find that developers were most sensitive to density restrictions and parking requirements. The average development in the Vermont/Western area had 112% of the maximum allowable residential density and 94% of the minimum required parking. Koreatown’s average development had 99% of the maximum density and 88% of the required parking. But, there was variation by area and whether a building was affordable or market rate, apartment or condominium, and by development size. Additionally, regulatory implementation can matter as much as the written regulations themselves. I recommend that cities take an evidence-based approach to reforming regulations and implementation processes.     

脑络欣通对大脑中动脉阻塞再灌注模型大鼠神经干细胞增殖分化的影响

目的 观察脑络欣通对大脑中动脉阻塞再灌注（middle cerebral artery occlusion-reperfusion,MCAO-R）模型大鼠神经干细胞增殖分化的影响。方法 采用线栓法复制MCAO-R大鼠模型,将30只健康雄性SD大鼠随机分成假手术组、模型组和给药组。分别采用神经功能评分和TTC染色鉴定模型大鼠的神经功能缺损和脑缺血面积,采用免疫荧光染色法观察大鼠海马CA1、CA2、CA3、齿状回（dentate gyrus,DG）区巢蛋白（Nestin）和神经丝蛋白-H（hypophosphorylated neurofilament-H,NF-H）表达水平。结果 给药组Nestin阳性表达主要发生在DG区,NF-H阳性表达主要发生在CA3区。脑络欣通促进神经干细胞增殖的作用在DG、CA1、CA2、CA3区均十分明显,以DG区尤为突出,促进神经干细胞分化的作用主要表现在CA3、DG、CA2、CA1区。与模型组比较,给药组大鼠海马各区的Nestin、NF-H阳性细胞均明显增多,差异具有统计学意义（P＜0.05）。结论 脑络欣通具有促进海马区神经干细胞增殖并分化为神经细胞的作用。     

Stealing into the wild: conservation science,plant breeding and the makings of new seed enclosures

Faced with pressing climatic changes, scientific and industrial interests are vying to develop crops that can survive drought, floods and shifting pest regimes. Increasingly, they look for solutions in an unlikely place: the gene pools of wild plants. Crop wild relatives (CWR) – species closely related to crops, including their ancestors – offer breeders the allure of retracing the domestication bottleneck, infusing genomes of modern crops with ‘lost’ genetic variety. Yet wild relatives also confront threats from climate change, urbanization and expansion of industrial agri-food. Thus, CWR, seen as both salvational and threatened, have become an international conservation and food-security priority. It is my contention that, in their common project to harness wild-relative potential, conservation and breeding science are co-evolving to extend seed commodity relations into new spheres. I examine enclosures along two fronts: first within ‘systematic CWR conservation’, where ‘in situ’ approaches, typically regarded as empowering and sustainable alternatives to ‘ex situ’, instead may support a complementary system of value extraction; second, in breeding and biotechnology research, which produces new value for CWR while profoundly shaping upstream conservation priorities. An important finding is that although today’s ‘ex situ-centric’ complementarity favors dispossession, an ‘in situ-centric’ approach could foster democratic renewal of biocultural diversity.     

Telling the stories of others: claims of authenticity in human rights reporting and comics journalism

ABSTRACT

There are various intermediaries bearing witness to distant conflicts and atrocities. They travel to distant parts of the world to collect different kinds of evidence and stories, motivated by the assumption that knowledge can evoke change. This article asks how authenticity is claimed in this context of humanitarian witnessing. It focuses on two, at first sight quite different, practices of representation: NGO human rights reporting and comics journalism, also known as graphic reporting. It argues that representations of first-hand access to sites and people involved in abuses, or of ‘having been there’, figure centrally in establishing authenticity and thereby truth. The article discusses two techniques through which first-hand truth claims are performed: representations of field research methodologies, and personifications of truth in the figure of the witness. The intermediaries chosen for an in-depth study are the human rights NGO Human Rights Watch and the US comics journalist Joe Sacco.     

Mobility in pastoral societies of Northern Mali: Perspectives on social and political rationales

Since the 1980s, the so-called “nomadic” populations in the regions of Northern Mali and Niger have embarked on an extensive process of settlement. Today they mostly live in villages or “settlement sites”. But, at the same time, individuals and small groups among these same populations have considerably enlarged their area of mobility and accelerated the rate and the value of the trade in which they engage. These two phenomena could, at first sight, appear contradictory. But the observation of empirical situations shows, rather, compatibilities, similarities even, between these two concomitant phenomena. Building on innovative debates conducted in geography and sociology, this article puts forward the hypothesis that the building of villages, as well as integration into military bases and barracks, proceeds from (social) rationales of mobility, just as much as transhumance, journeys, migration. Much more than a simple displacement in space, the notion of mobility could describe an “art of doing”, a way of being to others and to the world.     

《鹿特丹规则》下无单放货解决机制：从凭保函放货到凭指示放货

《鹿特丹规则》对无单放货问题设计了新的解决机制，通过使特定条件下的无单放货合法化，试图减轻承运人的负担，平衡船货双方的利益。采取规范分析的方法，对这一机制进行解构，论述其给各当事方的法律地位所带来的变化，认为对现有制度进行改良可能是更好的选择。
