‘Street Music’, Urban Ethnography and Ghettoized Communities

Hip‐hop is a definitively urban movement, born in the crisis of the Fordist city and rooted in the 1970s street culture of poor and working‐class African Americans and Latinos in New York City. Engaging with the contributions of Beer and Lamotte, this essay addresses two questions. Firstly, can we understand hip‐hop as a politics of resistance, a social movement rooted in a claim on urban space and a practice of urban citizenship? And secondly, is hip hop, and particularly rap music, a form of urban and regional research? I argue that as a primarily artistic movement and black expressive culture (subject to commercial imperatives), hip‐hop has a layered and complex relationship with the social, political and spatial fabric of urban America. The complexity of this relationship renders problematic attempts to understand hip‐hop as urban ethnography or as a resistance politics. I conclude by discussing the potential of an engagement between hip‐hop and critical urban studies.

Economic Design of EWMA Charts with Variable Sampling Intervals

Control charting is a graphical expression and operation of statistical hypothesis testing. In the present paper, we develop the economic design of the variable sampling intervals (VSI) exponentially weighted moving average (EWMA) charts to determine the values of the six test parameters of the charts (i.e., the sample size, the long sampling interval, the short sampling interval, the warning limit coefficient, the control limit coefficient, and exponential weight constant) such that the expected total cost is minimized. The genetic algorithm (GA) is applied to search for the optimal values of the six test parameters of the VSI EWMA chart, and an example is provided to illustrate the solution procedure. A sensitivity analysis is then carried out to investigate the effects of model parameters on the solution of the economic design.     

国有企业财务预警分析的新视觉

2006年按照中央对国有企业改组、改制的进程和规划,所有国企将在这一年完成身份的改变,引入股份制,完全按照股份制决策,懂事会选举,聘任,解聘,政府不再包干企业的亏损,改制后的国企财务预警意识必然比以往更加重要,本文通过引用“利润分块责任制-简易法”从另一个视角对改制后国有企业的财务预警进行分析。     

马克思的平均利润与生产价格理论及其当代价值

平均利润与生产价格理论是马克思经济学说的重要组成部分,是马克思剩余价值分配理论的基石。这一理论主要包含成本价格、利润、平均利润、生产价格、部门竞争、利润率等基本范畴,如果撇开资本的特殊外壳,从一般视角来看,它对于我国国有企业经营机制转换与宏观调控政策选择都具有十分显著的现实指导价值。
