The influence of organizational identification on organizational knowledge management (KM)

Information technology (IT) outsourcing vendor organizations contain isolated business units whose creation and sustenance greatly facilitate business operations. But they also introduce important challenges for organizational knowledge management (KM). In this paper, based on 7 months of intensive field-work at India Inc., a leading Indian IT firm, we looked at how members’ identification with two organizations, their own and their client organization, influences their compliance with an organizational KM initiative. The findings show that members have difficulties in complying with the expectations of the organizational KM initiative owing to a stronger identification with their client organizations. At the same time, they comply readily with KM initiatives at the business unit level. The findings show that KM managers at India Inc. use the help of middle level managers in the business units in their efforts to improve members’ compliance with organizational KM. Theoretical and managerial implications of the study are discussed.

Bayesian Analysis of Two-Regime Threshold Autoregressive Moving Average Model with Exogenous Inputs

We consider Bayesian analysis of threshold autoregressive moving average model with exogenous inputs (TARMAX). In order to obtain the desired marginal posterior distributions of all parameters including the threshold value of the two-regime TARMAX model, we use two different Markov chain Monte Carlo (MCMC) methods to apply Gibbs sampler with Metropolis-Hastings algorithm. The first one is used to obtain iterative least squares estimates of the parameters. The second one includes two MCMC stages for estimate the desired marginal posterior distributions and the parameters. Simulation experiments and a real data example show support to our approaches.     

民族村寨旅游地游客相对剥夺感的生成与应对——以西江苗寨为例

民族村寨旅游地旅游业蓬勃发展的同时,存在难以满足游客高质量体验的现实问题。较差的旅游体验很有可能诱发游客的相对剥夺感,尤其是有参照比较的情况下。游客相对剥夺感影响其旅游态度和行为,游客对旅游地的愤怒、敌视及攻击行为严重影响旅游地的旅游形象及潜在游客的旅游选择,最终对旅游地的可持续发展产生深远影响。本文以西江苗寨为案例,以游客点评数据为基础,深入探讨分析游客相对剥夺感的生成机理及应对措施。研究发现,游客旅游体验与参照比较的负向差异创造了相对剥夺感生成的诱发情境。游客相对剥夺感的生成经历游客认知、游客评价及与公平相关的情感反应三个阶段,只有当游客感知的不公平超出其情感容忍度时,才会真正产生相对剥夺感。不仅如此,游客的相对剥夺感表现为纵向—横向及个体—群体两个维度四种类型,游客现实感知的相对剥夺感可能为一种或几种类型的复合。在此基础上,提出民族村寨旅游地应对游客相对剥夺感的可操作性措施和建议。

高校学生社团法律问题研究

高校学生社团是高校学生行使公民结社权的表现形式,对其管理属于公法范畴.高校学生社团内部法律关系比较混乱,代表性不强;其外部法律关系严谨,管理规定合法性让人质疑.高校学生社团具有促进大学自治、维护学生权益等法律价值.     

税收激励与企业劳动雇佣——来自薪酬抵税政策的“准自然实验”

在经济下行压力不断加大的形势下,如何“稳就业”成为了各界关注的热点问题。本文以2008 年推行的薪酬抵税政策作为“准自然实验”捕捉企业税负的外生变化,并以2000-2018 年A 股上市公司数据作为研究样本,利用双重差分法考察了税收激励与企业雇佣行为之间的因果关系。实证结果表明:薪酬抵税政策带来了额外的税收优惠,进而促进了企业的雇佣需求,在有效排除共同趋势、预期效应、政策叠加效应以及反向因果问题后,这一结论依然稳健;异质性检验中发现,薪酬抵税政策对企业雇佣的激励效应在民营企业,成本转嫁能力较弱、劳动密集度较高以及处于市场化程度较高区域的企业中表现更加明显,这意味着企业对劳动力成本的变化越敏感,这一政策的作用效果就越好;薪酬抵税政策显著地提升了企业的经营绩效。本文的研究有助于深入理解税收影响企业行为的微观机理,对于政府利用税收政策扩大就业具有重要启示。     

Reversible jump Markov chain Monte Carlo algorithms for Bayesian variable selection in logistic mixed models

In this article, to reduce computational load in performing Bayesian variable selection, we used a variant of reversible jump Markov chain Monte Carlo methods, and the Holmes and Held (HH) algorithm, to sample model index variables in logistic mixed models involving a large number of explanatory variables. Furthermore, we proposed a simple proposal distribution for model index variables, and used a simulation study and real example to compare the performance of the HH algorithm with our proposed and existing proposal distributions. The results show that the HH algorithm with our proposed proposal distribution is a computationally efficient and reliable selection method.     

The sociolinguistics of exogamy: Dialect acquisition in a Zhuang village

Adult dialect acquisition is typically studied in relatively idiosyncratic situations where adults happen to move to another community. But how does dialect acquisition play out in indigenous minority societies that have systemic adult migration due to exogamy? Do the in‐married spouses acquire the local variety? Why or why not? How much do they acquire? We investigated an indigenous Zhuang community in southern China. Sociophonetic analyses of in‐married women and local villagers show that the in‐married women acquired the local variety in most respects but not in aspirated consonants. To the limits of their phonological ability as adult learners, the wives followed the local sociolinguistic norm: they acquired the husbands’ variety. By contrast, in societies experiencing greater external cross‐cultural contact, exogamous women sometimes use their liminal status to challenge such gendered sociolinguistic expectations. Comparing the present study with outcomes in different societies, we lay the foundation for a typology of the sociolinguistics of exogamy. In this way, we help expand the study of language and gender toward new horizons and under‐represented social settings.
