Moving beyond the rational choice debate via social capital: The study of illegal private protection

In the context of the epistemological and methodological debates about rational choice (RC) sparked by Green and Shapiro and the subsequent rejoinders, Hindmoor made the theoretical claim that there is now an opportunity for RC to be enhanced and for past debates to be set aside by incorporating different theoretical perspectives into RC. This article presents an example of one context in which this can be done: the study of illegal private protection (IPP) produced by organised criminals and corrupt officials. It extends a rational theory of criminal protection to enable the simultaneous analysis of corrupt protection and augments this approach with theories of social capital (SC). Both positive and negative forms and effects of SC are considered. This approach highlights a middle ground between advocates and critics of RC, demonstrating a capacity to explain patterns in the production of IPP between organisations and across countries.

针对格林、沙皮罗与弗里德曼的否定者所发起的有关理性选择的认识论及方法论论战,辛德摩尔提出一个理论主张：现在正可以通过吸纳不同的视角而弘扬理性选择,以往的辩论可置之一旁。本文讨论了一个可行的案例：有组织犯罪分子造成的非法私人保护。作者应用理性理论于犯罪保护,对腐败保护做了分析,并用社会资本理论扩展了这一方法。作者对社会资本理论的正负短长做了分析。这样的研究强调了介于理性选择理论赞同方与反对方的中间地带,展示对于组织间及跨国非法私人保护的产生的解释能力。     

A Collision of Masculinities: Men,Modernity and Urban Transportation in American-Colonial Manila

Abstract:

Early twentieth-century Manila saw the motorisation of its urban transport system. This was a significant transformation not only because of the technological changes it brought about but more importantly because of its role in shaping the highly gendered discourse of colonial modernity. Motorised vehicles, like the streetcar and the automobile, were trumpeted as masculine and modern machines by America’s civilising mission. This colonial discourse was continuously shaped and subverted by a collision of masculinities coming from different directions. This essay will focus on four different male groups in an effort to understand how transport motorisation influenced their sense of masculinity. White American colonisers imagined themselves as modern men destined to bring civilisation to the colony through technology. The native elites used the coloniser as their model by appropriating the symbols of masculine modernity. While the male workers of the modern transport sector gained knowledge of and access to the domains of those in power, those in the traditional sector became targets of vilification by the native and colonial elites. Instead of a duel between two sets of masculinity (coloniser vs. colonised) what emerged was a complex set of relationships influenced by the socioeconomic differences that separated these four groups.     

Learning from history? From Soviet collapse to the ‘new’ Cold War

Many moments in what we now rather lamely call the ‘end of the Cold War’ have been examined in detail. However, within the extraordinarily rich literature that has arisen over the past 25 years, little attention has been paid thus far to one very important problem: the part played by ‘history’ in shaping the way different actors tried to make sense of what was going on around them in a time of rapid transition.     

The p‐Compact‐regions Problem

The p‐compact‐regions problem involves the search for an aggregation of n atomic spatial units into p‐compact, contiguous regions. This article reports our efforts in designing a heuristic framework—MERGE (memory‐based randomized greedy and edge reassignment)—to solve this problem through phases of dealing, randomized greedy, and edge reassignment. This MERGE heuristic is able to memorize (ME of MERGE) the potential best moves toward an optimal solution at each phase of the procedure such that the search efficiency can be greatly improved. A dealing phase grows seeded regions into a viable size. A randomized greedy (RG of MERGE) approach completes the regions' growth and generates a feasible set of p‐regions. The edge‐reassigning local search (E of MERGE) fine‐tunes the results toward better objectives. In addition, a normalized moment of inertia (NMI) is introduced as the method of choice in computing the compactness of each region. We discuss in detail how MERGE works and how this new compactness measure can be seamlessly integrated into different phases of the proposed regionalization procedure. The performance of MERGE is evaluated through the use of both a small and a large p‐compact‐regions problem motivated by modeling the regional economy of Southern California. We expect this work to contribute to the regionalization theory and practice literature. Theoretically, we formulate a new model for the family of p‐compact‐regions problems. The novel NMI introduced in the model provides an accurate, robust, and efficient measure of compactness, which is a key objective for p‐compact‐regions problems. Practically, we developed the MERGE heuristic, proven to be effective and efficient in solving this nonlinear optimization problem to near optimality. El problema de regiones compactas tipo p (p‐compact regions) consiste en la búsqueda de la agregación de n unidades espaciales atómicas que produzca regiones contiguas de tipo p‐compacto. Este artículo reporta los esfuerzos de los autores en el diseño de un marco heurístico MERGE (memory‐based randomized greedy and edge‐reassignment) el cual resuelve este problema a través de las fases de la negociación (dealing), codicia aleatorizada (randomized greedy), y la reasignación de bordes (edge reassignment). El heurístico MERGE es capaz de memorizar ( ME de MERGE) los mejo)res desplazamientos posibles hacia una solución óptima en cada fase del procedimiento de tal manera que la eficiencia de la búsqueda puede ser mejorada en gran medida. La fase de negociación crea regiones “sembradas” aleatoriamente y las hace crecer en diferentes tamaños . El componente de codicia aleatorio (RG de MERGE) completa la fase de crecimiento de las regiones y genera un conjunto factible de regiones tipo p. La reasignación de bordes se realiza vía una búsqueda local (E de MERGE) que afina los resultados con el fin the alcanzar los objetivos. Además, el enfoque propuesto aquí utiliza el momento de inercia normalizado (normalized momento of inertia‐NMI) como método para el cálculo de la compacidad de cada región. El artículo discute en detalle el funcionamiento de MERGE y cómo esta nueva medida compacidad puede integrarse perfectamente en las diferentes fases del procedimiento de regionalización propuesto. Para ilustrar y evaluar el desempeño de MERGE, el metodo es aplicado a dos problemas de p‐compact regions, uno grande y uno pequeño, basados en el modelado de la economía regional del sur de California. Los autores esperan que este trabajo contribuya a la literatura teórica y práctica de la regionalización. En términos teóricos, se formula un nuevo modelo de la familia de problemas de p‐compact regions. El NMI equipa al modelo con una novedosa forma de obtener una medida exacta, robusta y eficiente de compacidad, que es un objetivo clave para los problemas región compacta tipo p. En términos prácticos, se desarrolla MERGE, un procedimiento heurístico que ha demostrado ser eficaz y eficiente en la solución de este problema de optimización no lineal de manera casi óptima. p紧凑区域问题包含寻找一种聚集方法,将n个不可分割的空间单元集合成p紧凑的邻近区域。本文阐述了一种启发式架构MERGE(基于记忆的随机贪婪和边界再赋值算法),通过处理、随机贪婪和边界再分配这几个阶段解决p紧凑问题。MERGE启发式框架能存储 处理过程每个阶段中,向一个最优解的潜在最佳移动方式,从而可极大地提升搜索效率。一个处理阶段可将种子区域生长到可行大小。而一个随机贪婪阶段能完成区域增长并生成p区域的可行集。在边界再分配的局部搜索阶段对结果进行微调以达到更好的目标。此外,引入标准化的惯性矩作为每个区域紧凑度计算的选择方法。本文详细讨论了MERGE的工作原理,以及这种新的紧凑度测算方法如何能无缝地整合到所提出的区域化流程的不同阶段。通过在南部加州区域经济建模中一小一大两个p紧凑区域问题的应用,对MERGE的性能进行评估,期望该工作能够对区域化理论和实践作出贡献。理论上,提出了可解决p紧凑区域这类问题的新模型。在模型中引入新颖的标准化惯性矩这一精确的、鲁棒的和有效的紧凑度度量方法,是解决p紧凑区域问题的关键目标;实践上,本文发展了MERGE启发式框架,并证明了它在解决这种非线性优化问题近优性的有效性和高效性。     

A Life in Maps: Leo Bagrow,Imago Mundi,and the History of Cartography in the Early Twentieth Century

ABSTRACT:

This essay provides a critical commentary on the life of Leo Bagrow (1881–1957), the founding editor of Imago Mundi, drawing on previously unused correspondence from the journal’s archive, recently catalogued by the British Library in London. Bagrow’s experiences in the three European cities in which he lived and worked (St Petersburg, Berlin and Stockholm) are examined afresh and new insights are provided about the complex intellectual and sometimes political objectives and motivations of Bagrow and his fellow map dealers, map collectors and map historians. Particular attention is paid to the productive but often strained relationships between Bagrow and the expanding global network of map historians with whom he collaborated while establishing and editing Imago Mundi between 1935 and his death. This network was divided into four distinct and to some extent rival constituencies (university academics, map librarians, map collectors and map dealers). The essay examines how Imago Mundi, under Bagrow’s often confrontational editorship, emerged as the central co-ordinating forum through which these constituencies communicated with each other and within which the foundations for the modern discipline of map history were established.     

Bernardo del Carpio en el Poema de Fernán González

The focus of the Poema de Fernán González falls squarely on its protagonist, the tenth-century Castilian warrior lord known to us today as Count Fernán González. Nevertheless, a third of the poem is devoted to the narration of events and prominent figures who preceded the Count. Most notable among these is Bernardo del Carpio, a fully fictitious epic hero who prefigures the Count in his willingness to fight for the independence of the Castilian nation. This analysis of the narration of Bernardo's heroic deeds against the invading army of Charlemagne is meant to clarify lingering doubts about the sources of the poem and their mode of transmission.
