An Empirical Study on the Relation Between the Critical Angle for Bullet Ricochet and the Properties of Wood

The properties of a bullet, an object, and the incidence angle determine whether the bullet will penetrate, perforate, or ricochet. In this study, the critical angle for ricochet was established for .32 Auto and 9 mm Luger bullets on Abachi, Southern Yellow Pine, Beech, and Ipe wooden boards. Results show that the critical angle differs depending on caliber and wood type. The critical angle is higher for .32 Auto bullets than for 9 mm Luger bullets and increases with increasing wood density and Janka hardness. The established critical angles for ricochet on the lightest and softest wood (Abachi) are 10.4° and 10.3° for .32 Auto and 9 mm Luger, respectively. For the heaviest and hardest wood (Ipe), the angles were 45.0° and 33.4°, respectively. The combined results on the four tested woods show a strong linear relationship between both the density and the hardness and the critical angle for both calibers.     

Why Subjectivity Matters: Critical Theory and the Philosophy of the Subject

Abstract

In this paper it is argued that Habermas' critique of German Idealism is misguided and that his rejection of the philosophy of the subject is unjustified. Critical Theory needs to recognise the importance of subjectivity for all social philosophy if its theoretical aims are to be achieved. In order to demonstrate the relevance of subjectivity to Critical Theory the essay draws on analytic philosophy of mind and on the work of Manfred Frank and Dieter Henrich.

Negotiating for Money: Adding a Dose of Reality to Classroom Negotiations

Negotiation and conflict management courses have become increasingly common in business schools around the world. Frequently, these courses employ role plays and simulations to encourage students to try new strategies, tactics, techniques, and behaviors. While these simulations generally are designed to elicit realistic negotiation dynamics, they often lack the full emotional tension inherent in actual negotiations. One possible reason for this reduced tension is that no tangible resources, such as money, are at stake. This article describes an experiment in which MBA students paid a player's fee at the beginning of a negotiation course, and in which each negotiation exercise had an actual dollar value at risk. The article reports some results from this experiment and offers suggestions for instructors who might seek to add a player's fee to their own courses. In general, most students found the experience valuable, as it provided performance benchmarks while focusing their attention more sharply on risks and returns.     

公共政策评估多元模式的困境及其解决的哲学思考

通过对政策评估模式发展的历史考察,文章分析了政策评估模式由单一向多元转变的逻辑以及多元评估模式的困境。并以南水北调移民政策评估为例,解读了当今多元理性下的政策评估仍然存在的多元利益界定不准确、评估模式结构固化等诸多问题。要从根本上解决多元理性下政策评估模式的问题,必须实现政策评估哲学思维的进一步转变,而这一转变应遵循批判性政策分析理论、利益相关者理论以及理性选择理论的基本价值。     

The animal advocacy movement in the Baltic states: links to other social justice issues and possibilities for intersectional activism

ABSTRACT

This article focuses on the animal advocacy movement (AAM) in the Baltic countries of Estonia, Latvia, and Lithuania. Taking an intersectional perspective, I examine whether and how key animal activists in the Baltics see links between animal rights and other social justice issues. I also consider how the movement communicates its messages to the general public in settings where ideas around animal justice and possibilities for animal advocacy are relatively recent and unfamiliar. This analysis contributes to debates regarding possibilities for intersectional activism and collaboration between social justice movements in the Baltics and beyond.     

Towards security governance as a critical tool: a conceptual outline

This article argues that security governance can and should be reframed as a critical tool that enables us to understand and reappraise concrete practices of security provision. Security governance needs to move beyond the functional mapping of different governing arrangements and the presumption that security governance leads to effective and legitimate problem-solving in a quasi-automatic manner. In this article, we propose a framework that identifies the essential characteristics of security governance and turns them into critical questions with the aim to reveal persisting frictions and dilemmas. First, we trace the rise of security governance as concept and practice over the past decade and identify its central characteristics with regard to prerequisites, structures and consequences. Second, we reframe the core characteristics of security governance into critical questions and thereby develop an understanding of security governance as a critical tool. Finally, we illustrate the relevance of this approach with examples from EU security governance.     

Editors’ introduction: critical terrorism studies: practice,limits and experience

The articles in this special issue are drawn from papers presented at a conference titled Critical Terrorism Studies: Practice, Limits and Experience. The conference was organised by the Critical Studies on Terrorism Working Group of the British International Studies Association (BISA). The event was supported by both a BISA workshop grant and by Loughborough University’s Centre for the Study of International Governance (CSIG) and was held at Loughborough University from 9–10 September 2013. The conference aimed to explore what we know about terrorism and counterterrorism and importantly to ask how we know it. Reflecting the recent “materialist”, “everyday”, “experiential” and “narrative” turns in the fields of International Relations (IR), Geography and Cultural Theory, the event brought together scholars and practitioners to reflect on practices of research and knowledge production in Critical Terrorism Studies and related fields. The articles in this special issue reflect those aims.     

Subaltern connections: Brazilian critical geographers,development and African decolonisation

Abstract

This article explores the relations to Africa and African decolonisation of three key figures in Brazilian critical geographies and development studies, Manuel Correia de Andrade (1922–2007), Josué de Castro (1908–1973) and Milton Santos (1926–2001). Based on an analysis of their works and unpublished archives, I argue the radical Third World perspectives these intellectuals expressed anticipated later critiques of development as a neocolonial device. Drawing upon current literature on decolonisation, international conferencing and anti-racist solidarity networks, I discuss these matters in relation to these authors’ interest in cultural diversity and internal colonialism. Crucially, they developed this sensitivity in the Brazilian Northeast, a region especially shaped by Afro–Brazilian and Indigenous cultural legacies. While supporting anti-imperialist nationalisms in the Third World, these Brazilian scholars fostered multilingual, internationalist and cosmopolitan activism and scholarship. This is revealed by the study of the transnational networks they developed during exile and the various persecutions that many of them suffered after the 1964 military coup. Finally, I argue these works can substantiate recent claims to ‘decolonise’ geography and development studies, on the condition that these fields of study take seriously their anti-imperial traditions and their ‘voices from the South’.
