Goodness of fit for the inverse Gaussian distribution

For testing the fit of the inverse Gaussian distribution with unknown parameters, the empirical distribution-function statistic A² is studied. Two procedures are followed in constructing the test statistic; they yield the same asymptotic distribution. In the first procedure the parameters in the distribution function are directly estimated, and in the second the distribution function is estimated by its Rao-Blackwell distribution estimator. A table is given for the asymptotic critical points of A². These are shown to depend only on the ratio of the unknown parameters. An analysis is provided of the effect of estimating the ratio to enter the table for A². This analysis enables the proposal of the complete operating procedure, which is sustained by a Monte Carlo study.     

薪酬策略与公司竞争战略的匹配机制研究

文章通过对185家企业的实地调研,比较了薪酬策略和公司竞争战略的两种匹配模式:中介匹配和调节匹配.否定了中介匹配模式,支持了调节匹配模式,从而解决了薪酬管理研究中长期存在的争议:两者到底是如何匹配的.公司竞争战略并不能自发地促生出相应的薪酬策略,而是需要相关部门较为独立地开发出相应的薪酬策略与之配套.最后,根据研究发现并提出了一些增进薪酬策略与公司竞争战略匹配度的建议.     

Fit and Skill in Employee Selection: Insights from a Study of Headhunters

We draw upon evidence from a qualitative study of headhunters to provide insights into the character and importance of candidate fit and skill for the selection of a broad range of white-collar employees. Headhunters suggest that the fit of a job candidate is assessed at two levels, one corresponding with a general compatibility with organization-level norms, culture, and strategy, the other corresponding more closely with traits and characteristics of the person or persons with whom the job candidate actually interviews. Skill—a factor which is largely neglected by those who tout the importance of fit—also plays an important and independent role in employee selection. Stalls that influence the selection of employees from a pool of candidates tend to be highly specific if not idiosyncratic, and take the form of what headhunters call hot buttons. We conclude by discussing the conceptualization, causes, and implications of fit; we also consider how the importance of fit and hot buttons challenges the explanatory logic of standard accounts of labor-market success.     

The Management of Violence in a Conflict Organization: The Case of the Abu Sayyaf

The Abu Sayyaf is an organization which has left a trail of mayhem and murder in the southern Philippines for more than a decade. It has gained international notoriety through several high profile mass kidnappings. This article looks at how the Abu Sayyaf has managed to survive and at times prosper despite the state's efforts to eradicate it. By using organizational analysis the paper demonstrates how the Abu Sayyaf has developed structures and processes which make it such a deadly force. The organization has succeeded in gaining considerable fit with the environment in which it operates.     

青年社工的职业认同：内驱还是外驱？——基于珠三角地区25所社工机构的调查

伴随社会工作的全面铺开和受重视程度的提高,当前青年社工职业认同的整体水平高于以往研究。从影响因素来看,包括性别、年龄、受教育程度和婚姻状况的个体特征和包括社工工作年限和所在社工机构的规模的职业特征对青年社工的职业认同都有不同程度的影响。而从作用机制来看,个体自身因素和环境因素共同作用于青年社工的职业认同。路径分析表明,个人-组织匹配对青年社工职业认同的效用高于公共服务动机。因此,要提升青年社工的职业认同进而提高社工队伍的职业化水平一方面要注重引导青年社工投身职业,服务公众的“初心”情怀,另一方更要注重创建与优化工作环境,为青年社工提供职业支持资源,提高个人-职业匹配,实现青年社工个人与机构发展的“双赢”。     

社交电商情境下消费者预期价值研究——基于说服抵抗的中介作用及内容煽动性的调节作用

社交电商的发展使得网红带货成为时下最流行的流量变现方式,商家利用社交媒体投放产品广告,借助网红博主的影响力为产品打开市场并建立口碑。基于说服抵抗理论和信息操纵理论,通过两个实验研究社交电商背景下网红博主与产品之间的契合程度对于消费者对产品预期价值的影响,以及该过程中说服抵抗的中介作用和博文内容煽动强度的调节作用。结果表明：与博主-产品契合度低的博文推广内容相比,博主-产品契合度高的博文推广内容能使消费者对产品产生更高的价值预期,且此过程以说服抵抗为中介。同时,内容煽动强度发挥调节作用,当煽动强度存在强弱差异时,不同博主-产品契合度的产品推广博文对消费者预期价值的影响差异逐渐加大。     

个人-组织匹配、工作满意度与员工离职意向关系的实证研究

从个人-组织匹配的理论视角出发,用实证方法研究企业的个人-组织匹配与工作满意度之间的关系,以及它们对员工离职意向的影响.研究结果表明,个人-组织匹配对工作满意度起到显著正向影响;个人-组织匹配对员工离职意向起到显著负向影响;工作满意度对员工离职意向起到显著负向影响;工作满意度中的2个维度--工作压力满意度和管理因素满意度在个人-组织匹配对离职意向的影响中起中介作用.     

员工积极组织行为影响因素的实证研究:工作-家庭冲突的中介作用

本研究对505名员工及他们的124名直接主管按照4∶1的比例做了配对调查并对调查结果进行多层数据分析,考察工作压力、工作匹配度、工作-家庭冲突对员工积极组织行为的影响,分析了工作-家庭冲突的中介作用以及员工外倾性人格特质的调节作用。结果发现,工作-家庭冲突对员工的积极组织行为产生显著的负向影响;工作-家庭冲突在工作匹配、工作压力与员工积极组织行为的关系中起到中介作用;员工外倾性人格特质对工作-家庭冲突与员工积极组织行为之间的关系有调节作用,即外倾性人格特质能够降低工作-家庭冲突的负面影响,减弱其对员工积极组织行为的不利影响。     

Complementary person-supervisor fit: An investigation of supplies-values (S-V) fit,leader-member exchange (LMX) and work outcomes

By applying the supplies-values (S-V) fit approach from the complementary person-environment (P-E) fit literature to the leader-employee perspective, and drawing upon social exchange theory, we examine how fulfillment of different work values is related to Leader-Member Exchange (LMX) and work outcomes. First, polynomial regression analyses combined with response surface analysis of data collected at two time points (N = 316) showed that LMX (Time 2) was higher the more the leader fulfills the employee's work values (Time 1). Second, LMX (Time 2) was higher when leader supplies (Time 1) and employee work values (Time 1) were both high than when both were low. Third, analyses of data from a sub-sample of matched leader-employee dyads (N = 140), showed that LMX (Time 2) played a mediating role on the relation between S-V fit (Time 1) and work outcomes (Time 2). Specifically, we found eight out of 10 relationships between S-V fit (Time 1) and leader-rated task performance and OCB (Time 2) to be fully mediated by LMX (Time 2). LMX (Time 2) partially mediated the relation between S-V fit (Time 1) and job satisfaction (Time 2) as only two out of five relationships were fully mediated.     

A Diversity Index for Model Space Selection in the Estimation of Benchmark and Infectious Doses via Model Averaging

In chemical and microbial risk assessments, risk assessors fit dose‐response models to high‐dose data and extrapolate downward to risk levels in the range of 1–10%. Although multiple dose‐response models may be able to fit the data adequately in the experimental range, the estimated effective dose (ED) corresponding to an extremely small risk can be substantially different from model to model. In this respect, model averaging (MA) provides more robustness than a single dose‐response model in the point and interval estimation of an ED. In MA, accounting for both data uncertainty and model uncertainty is crucial, but addressing model uncertainty is not achieved simply by increasing the number of models in a model space. A plausible set of models for MA can be characterized by goodness of fit and diversity surrounding the truth. We propose a diversity index (DI) to balance between these two characteristics in model space selection. It addresses a collective property of a model space rather than individual performance of each model. Tuning parameters in the DI control the size of the model space for MA.
