Casinos,casino size,and crime: A panel data analysis of Michigan counties

Growth in legal gaming in the United States over the past quarter century or so is well-documented. One important factor fueling this growth was the passage of the Indian Gaming Regulatory Act of 1988, which permitted Native American tribes to establish, under agreements or “compacts” with the states in which they are located, casinos offering what is known as Class III gaming: slot machines, blackjack, roulette, and other games. Since the passage of the Act, there have been 21 Native American casinos established in Michigan. Also, three non-Native American casinos opened in Detroit in 1999 and 2000. This growth in the number of casinos has sparked a wide-ranging debate over the social and economic impacts of casino development.The purpose of this research is to focus on the crime issue in the broader casino debate. We investigate the impact of these Michigan casinos on the rates of burglary, robbery, larceny and motor vehicle theft (property crimes) in casino host counties as well as in nearby counties. We employ a panel data set with annual observations on all 83 Michigan counties for the period 1994–2010. The dataset includes crime rates taken from the FBI crime data series, variables for the presence of a casino in a county or in a nearby county, the scale of a casino's operations as measured by revenues, and a variety of control variables suggested by the broader literature investigating the factors that determine crime rates generally.Our results suggest that in most cases the property crime rates studied are not affected by the presence or size of a casino in a county or in a nearby county. The largest such impact, which is negative, is for motor vehicle theft. The size of a casino does have a small positive effect on the motor vehicle theft rate.

中国被忽视的非正规经济：现实与理论

中国的“非正规经济”就业人员（即没有工作保障,缺少福利和不受国家劳动法保护的劳工）已占今天2．83亿城镇就业人员总数中的1．68亿,比正规就业人员要多出一倍半。但是,今目的中国国家统计机构尚未真正正视非正规经济就业人员统计。其部分原因是当前的主流经济（以及社会）理论——即主要来自20世纪60年代在美国盛行的“二元经济”理论、“三部门理论”和“橄榄型”社会结构理论——的误导。这些理论共同构成了50年代和60年代风行美国的“现代化”模式。本文扼要论述该模式的关键论点,进而回顾70年代和80年代发展经济学“革命”中有关学者对其所作的批评,以及后来新古典经济学在美国新保守主义领导下进行的“反革命”辩驳,重在揭示论争双方的意识形态化偏颇,并突出各自的洞见,提倡适当结合双方正确的见解,由此建立去意识形态化的理论观点,以助于理解今天非正规经济的现实。     

新零售下社区生鲜配送模式的综合评价

新零售模式下社区生鲜“最后500m”的冲刺已成为生鲜农产品快速配送的关键问题。基于目前已有的配送模式:“社区+便利店”模式、第三方配送以及众包模式,通过层次分析法从服务水平、配送成本、客户体验三个方面对三种配送模式进行量化分析,得出每种配送模式在各层次的权重。研究结果表明配送中降低配送成本是关键,减少货物赔损率、提高客户满意度才能实现有效率的配送。

不同剂型硝苯地平治疗高血压的药物经济学评价

目的评价抗高血压药硝苯地平临床常用三种不同剂型治疗高血压的临床效果和经济效益。方法选择90例高血压病患者随机分为三组,每组30例,分别口服硝苯地平普通片、缓释片和控释片治疗,并进行药物经济学分析。结果服药8周后各组患者血压均有明显下降,其中普通片、缓释片和控释片治疗高血压总有效率分别为93.33%、93.33%、96.66%,不良反应发生率分别为10.0%、6.6%、0.0%,成本-效果比分别为0.02、0.40、2.96,控释片相对于普通片的增量成本-效果比为85.43。结论硝苯地平缓释片虽其消费成本不是最低,但服法简单,副作用较少,综合评价是硝苯地平临床常用三种剂型治疗高血压的最佳剂型,特别适用于基层医院。     

Consuming dark tourism: A Thanatological Perspective

Despite increasing academic attention paid to dark tourism, understanding of the concept remains limited, particularly from a consumption perspective. That is, the literature focuses primarily on the supply of dark tourism; less attention, however, has been paid to the demand for ‘dark’ touristic experiences. This theoretical paper seeks to address this gap in the literature. Drawing upon the contemporary sociology of death, it explores the relationship between socio-cultural perspectives on mortality and the potential of dark tourism as a means of confronting death in modern societies. In so doing, it proposes a model of dark tourism consumption within a thanatological framework as a basis for further theoretical and empirical analysis of dark tourism.

A typology of students based on academic entitlement

Two hundred ninety-three university business students were surveyed using an academic entitlement (AE) scale updated to include new technologies. Using factor analysis, three components of AE were identified: grade entitlement, behavioral entitlement, and service entitlement. A k-means clustering procedure was then applied to identify four groups based on the relative strength of the AE components: the model student, under the radar, instructor as servant, and the privileged. These groups were further characterized by additional demographic (i.e., parental income) and classroom variables (i.e., instructor response times). Findings can help business educators gain better insight into the AE construct and devise more effective instructional strategies.
