Mobility Regimes in Practice: Later-life Westerners and Visa Runs in South-East Asia

Abstract

Studies of Western migrants in South-East Asia emphasise the importance of privilege, work and location within national boundaries in the construction of contemporary subjectivities. This article examines the role and relevance of cross-border mobility through the eyes of older, Western ‘visa runners’ with limited financial resources. Drawing on migrant experience of dwelling in and moving through Penang, Malaysia, I address the ways in which the mobility regimes of immigration frameworks and visa regulations become a formative aspect or otherwise of social practice and belonging. In focusing on the personal and social experience of visa running, this article transcends a methodological nationalist focus on identities and subjectivities within national spaces and highlights the variable role of people, places and life history in the forming of multi-layered attachments across national spaces in South-East Asia.     

Genocide Reconsidered: A Pragmatist Approach

The recent literature on genocide shows signs of taking what might be called a “processual turn,” with genocide increasingly understood as a contingent process rather than a singular event. But while this second generation's turn may be clear to those within the literature, the theory guiding the change is insufficiently specified. The theory regarding process and contingency is implicit, and, as such, genocide theory does not realize its full generative potential. The primary goal of this article is to provide a more robust theoretical framework for making sense of the continually evolving dimensions of genocide. It builds on the literature's existing foundations, most notably Mann's (2005) notion of “contingent escalations.” In the spirit of the recent revival of American Pragmatism in sociology, it draws on the work of Dewey, Mills, Follett, and Addams (among others) as part of a theoretical reconstruction using pragmatist concepts such as rupture, perplexity, vocabularies of motive, and experimentation to consider examples from the Rwandan genocide and show how we might explore the potential for non‐teleological intentionality on the part of genocidal actors. The result is an enhanced theoretical framework that offers “fresh eyes” for considering one of the worst (and most under‐theorized) social problems.     

论我国独立量刑程序的建构

量刑程序有英美法系的独立量刑程序和大陆法系的混合量刑程序之分。20世纪中叶以来,大陆法系国家开始出现向独立量刑程序转变的趋势。独立量刑程序阻隔了纯粹的量刑证据对法官心证的不当影响,符合"先罪后刑"的诉讼逻辑,有助于正确评估被告人的人身危险性,给予了控辩双方和被害人更多的参与量刑的权利和机会,因而更有利于量刑实体公正和程序公正的实现。随着我国对量刑公正的日益重视以及证据规则的逐步完善,有必要确立这一程序。我国刑事司法实践中的普通程序简易审、缓刑听证等实际上已经开始了创设该程序的初步尝试。与定罪程序相比,独立量刑程序应具有程序简化、证据规则宽松、证明标准较低、法官积极主动等特点。     

《红楼梦》亲属语译出中文化内涵的缺失

《红楼梦》中人物繁多,称谓复杂,在众多的中国古典文学名著中最能反映中国传统文化对称谓语的影响。本文以杨宪益夫妇所译之《红楼梦》为例,通过其亲属称谓词的翻译比较,来看其译出过程中造成的文化内涵的缺失,并试着探讨其在一定范围内的弥合策略。     

The quality and use of regulatory analysis in 2008

This article assesses the quality and apparent use of regulatory analysis for economically significant regulations proposed by federal agencies in 2008. A nine-member research team used a six-point (0-5) scale to evaluate regulatory analyses according to criteria drawn from Executive Order 12866 and Office of Management and Budget Circular A-4. Principal findings include: (1) the average quality of regulatory analysis, though not high, is somewhat better than previous regulatory scorecards have shown; (2) quality varies widely; (3) biggest strengths are accessibility and clarity; (4) biggest weaknesses are analysis of the systemic problem and retrospective analysis; (5) budget or "transfer" regulations usually receive low-quality analysis; (6) a minority of the regulations contain evidence that the agency used the analysis in significant decisions; (7) quality of analysis is positively correlated with the apparent use of the analysis in regulatory decisions; and (8) greater diffusion of best practices could significantly improve the overall quality of regulatory analysis.

Optimal Inventory Control with Retail Pre‐Packs

A pre‐pack is a collection of items used in retail distribution. By grouping multiple units of one or more stock keeping units (SKU), distribution and handling costs can be reduced; however, ordering flexibility at the retail outlet is limited. This paper studies an inventory system at a retail level where both pre‐packs and individual items (at additional handling cost) can be ordered. For a single‐SKU, single‐period problem, we show that the optimal policy is to order into a “band” with as few individual units as possible. For the multi‐period problem with modular demand, the band policy is still optimal, and the steady‐state distribution of the target inventory position possesses a semi‐uniform structure, which greatly facilitates the computation of optimal policies and approximations under general demand. For the multi‐SKU case, the optimal policy has a generalized band structure. Our numerical results show that pre‐pack use is beneficial when facing stable and complementary demands, and substantial handling savings at the distribution center. The cost premium of using simple policies, such as strict base‐stock and batch‐ordering (pre‐packs only), can be substantial for medium parameter ranges.     

劳动过程视角下农业技术应用的社会条件——弗里德兰的《制造绿金》及其启示

在《制造绿金》一书中,弗里德兰运用马克思主义的劳动过程理论,以美国生菜产业为例探索新技术应用的社会过程与社会条件,突出强调了“劳动者生产组织”命题对一项新技术采用的重要作用。同时有关作物结构的分析为商品系统分析方法的提出以及世界商品链、食品体系研究奠定了基础,这不仅拓展了农业社会学研究的边界,也为中国农业社会学研究提供了重要的借鉴意义。
