领导行为与人际关系对酒店企业群体内聚力的影响及其后果

以组织行为和管理理论中关于群体内聚力的讨论为基础,实证探讨了中国酒店企业中,领导行为与员工之间的人际关系对群体内聚力的影响,以及群体内聚力与员工工作满意感之间的关系.研究结果表明:人际关系、任务导向型领导行为和体恤支持型领导行为会正向影响群体内聚力,但创新适应型领导行为对群体内聚力的影响不显著;群体内聚力对员工工作满意感有显著正向影响;群体内聚力对于人际关系和员工工作满意感之间的关系,以及任务导向型领导行为和员工工作满意感之间的关系有完全的中介作用,对于体恤支持型领导行为和员工工作满意感之间的关系有部分的中介作用,但对于创新适应型领导行为和员工工作满意感之间的关系却无中介作用.最后,讨论了研究结果的应用.     

Factors Affecting Planned Unit Development Implementation

Planned unit developments (PUD) have been celebrated as one of the few means of escape from the stranglehold of Euclidean zoning but little is known empirically about their use and implementation. In this paper, I present quantitative data from Michigan exploring the factors affecting successful PUD implementation. Results indicate that citizen participation, emphasis of PUD regulations, PUD appeal and differences among key players during PUD review have significant impacts on successful PUD implementation. I also find that Michigan municipalities are more successful at achieving mixed-use, density, preservation, affordable housing, community facilities and design through PUDs than through other regulatory vehicles.     

Water Adherence Factors for Human Skin

On incidental dermal exposure to chemicals in water, a key exposure factor is the amount of water adhering to skin. Although soil adherence factors have been developed for risk assessment, measurements of water adherence on human skin have not been described. In the Environmental Protection Agency's (EPA's) dermal risk assessment guidance, dermal dose from environmental exposures is based upon the flux rate across the skin, which assumes that an unlimited amount of chemical is available for absorption. This assumption is applicable to certain exposure scenarios such as swimming and bathing. However, exposures to contaminated water frequently involve scenarios where the available chemical is limited by the amount of water adhering to the skin, for example, during accidental splashes. We conducted studies in human volunteers to investigate water adherence per unit area of skin after brief contact with water. In two sets of experiments, either water was applied with a micropipette to 10‐cm² areas of the lower leg, foot, and hand, or the foot and hand were briefly immersed in water. In males, using a micropipette, water adherence ranged from 1.93 (foot) to 7.13 μL/cm² (lower leg). In females, it ranged from 1.10 (lower leg) to 4.83 μL/cm² (hand). Hand and foot immersion resulted in relatively higher values of 6.89 and 5.17 μL/cm², respectively, in males, and 5.40 and 6.39 μL/cm² in females. Water adherence was affected by amount of body hair and type of exposure. Water adherence factors can be used to calculate the applied dose per unit area for exposures involving intermittent water contact.     

On the Existence of Monotone Pure‐Strategy Equilibria in Bayesian Games

We generalize Athey's (2001) and McAdams' (2003) results on the existence of monotone pure‐strategy equilibria in Bayesian games. We allow action spaces to be compact locally complete metric semilattices and type spaces to be partially ordered probability spaces. Our proof is based on contractibility rather than convexity of best‐reply sets. Several examples illustrate the scope of the result, including new applications to multi‐unit auctions with risk‐averse bidders.

国有企业社会成本的演变——关于武汉J厂的个案调查

在国有企业的社会成本问题日益威胁到企业的生存时，无论从国家还是企业的角度，都开始在社会成本方面寻求某些突破。本文拟以武汉J厂为个案，从单位体制、企业制度的角度分析国有企业社会成本的演变。对于社会成本的分离必须区别对待，而且是一个长期的过程。

'Race', Ethnicity and Child Welfare: A Fine Balancing Act

Western multi-racial societies continue to grapple with the‘best’ and ‘most desirable’ way to integrateracial/cultural minorities in mainstream society. The fieldof child welfare provides a fertile terrain in which to testthe prevailing debates and discussions. This paper exploressome key issues in ethnicity and child welfare and the implicationsof these for minority families and children, and the socialwork profession.

Moderate Deviation Principles for Empirical Covariance in the Neighbourhood of the Unit Root

In this paper, we consider the linear autoregressive model with varying coefficients θ_n∈[0,1). When θ_n tending to the unit root, the moderate deviation principle for empirical covariance is discussed, and as statistical applications, we provide the moderate deviation estimates of the least square and the Yule–Walker estimators of the parameter θ_n.
