Chinatown 2.0: the difficult flowering of an ethnically themed shopping area

Right in Amsterdam’s picturesque Canal Zone, on and around Zeedijk, Chinese entrepreneurs have carved out a presence in what seems like the local Chinatown. The businessmen have been targeting Asian and non-Asian customers by offering products that – to an extent – can be associated with Asia, China in particular. Since the early 1990s, individual entrepreneurs and their business organisations have campaigned for official acknowledgement of Zeedijk as an ethnic-only district and for governmental support of the enhancement of Chineseness. Following Hackworth and Rekers. [(2005). “Ethnic Packaging and Gentrification. The Case of Four Neighborhoods in Toronto.” Urban Affairs Review 41 (2): 211–236], we argue that this case challenges traditional understandings of ethnic commercial landscapes. In sharp contrast to the current orthodoxy, which would conceive the proliferation of such an ‘ethnic enclave’ as part of a larger process of assimilation, we have approached Amsterdam’s Chinatown first and foremost as a themed economic space: Chinese and other entrepreneurs compete for a share of the market and in doing also for the right to claim the identity of the area. What is the historical development of the Zeedijk area, how did Chinese entrepreneurs and their associations try to boost Chinatown and negotiate public Chineseness, and how did governmental and non-governmental institutional actors respond to those attempts?     

“It Is What It Is”: Masculinity,Homosexuality, and Inclusive Discourse in Mixed Martial Arts

In this article we make use of inclusive masculinity theory to explore online media representations of male homosexuality and masculinity within the increasingly popular combat sport of mixed martial arts (MMA). Adopting a case-study approach, we discuss narratives constructed around one aspirational male MMA fighter, Dakota Cochrane, whose history of having participated in gay pornography became a major talking point on a number of MMA discussion/community Web sites during early 2012. While these narratives attempted to discursively rescue Cochrane’s supposedly threatened masculinity, highlighting both his “true” heterosexuality and his prodigious fighting abilities, they also simultaneously celebrated the acceptance of homosexual men within the sport that Cochrane’s case implied. Thus, we suggest that these media representations of homosexuality and masculinity within MMA are indicative of declining cultural homophobia and homohysteria and an inclusive vision of masculinity, as previously described by proponents of inclusive masculinity theory.     

水质预报系统的MPI+OpenMP并行优化研究

OpenMP(Open Multi-Processing)能够在共享存储环境中获得理想的并行性能,MPI＋OpenMP混合并行编程模型更贴近于多核心集群的体系结构。在多核心集群上进行实验,混合模型相对串行程序可缩短95%的运算时间,加速比超过20。实验结果表明,该混合模型比纯MPI并行的系统具有更优的加速比和扩展性,是对纯MPI并行系统的一种改进。     

农业生产风险管理策略的研究

农业生产经营风险管理所涉及的风险因素很多,主要有:(1)单产变化;(2)价格变化;(3)新技术或新知识变化;(4)农业投入水平变化;(5)政府政策变化;(6)法律变化;(7)消费者偏好变化,等等。通过权衡风险和收益,采用适宜的管理策略来规避风险,提高收益,形成了一系列非确定性关系下的风险决策方法。联系河北省20世纪90年代以来农业生产的实际情况,探讨了各种主要的规避或减少农业生产风险的方法和策略,如利用偏相关系数最小的方法选择稳定的生产项目;采用多种经营以分散风险的组合策略;提高农业生产经营灵活性的诸多措施;利用二次规划以建立风险最小而又能保证一定收入水平的最优规划方法等。

An integrated approach for water resources decision making under interactive and compound uncertainties

In recent years, the issue of water allocation among competing users has been of great concern for many countries due to increasing water demand from population growth and economic development. In water management systems, the inherent uncertainties and their potential interactions pose a significant challenge for water managers to identify optimal water-allocation schemes in a complex and uncertain environment. This paper thus proposes a methodology that incorporates optimization techniques and statistical experimental designs within a general framework to address the issues of uncertainty and risk as well as their correlations in a systematic manner. A water resources management problem is used to demonstrate the applicability of the proposed methodology. The results indicate that interval solutions can be generated for the objective function and decision variables, and a number of decision alternatives can be obtained under different policy scenarios. The solutions with different risk levels of constraint violation can help quantify the relationship between the economic objective and the system risk, which is meaningful for supporting risk management. The experimental data obtained from the Taguchi's orthogonal array design are useful for identifying the significant factors affecting the means of total net benefits. Then the findings from the mixed-level factorial experiment can help reveal the latent interactions between those significant factors at different levels and their effects on the modeling response.
