新生代员工自我差异及其工作态度和行为的关系模型构建

新生代员工已逐渐成为中国劳动力市场的主力军,他们重视自我实现和自我满足,存在职场中现实自我状态与理想自我状态、应该自我状态经常不一致的情形,对新生代员工自我差异实施有效管理具有重要意义。文章基于以往研究文献,构建了新生代员工自我差异及其工作态度和行为的关系模型,采用逻辑推导的方式对理论模型分析发现,虽然新生代员工的自我差异会降低其工作投入和帮助行为,但程序公平氛围和自尊会对其消极效应起着正向的调节作用。最后提出了对新生代员工自我差异的管理建议。     

Estimating features of a distribution from binomial data

We propose estimators of features of the distribution of an unobserved random variable W. What is observed is a sample of Y,V,X where a binary Y equals one when W exceeds a threshold V determined by experimental design, and X are covariates. Potential applications include bioassay and destructive duration analysis. Our empirical application is referendum contingent valuation in resource economics, where one is interested in features of the distribution of values W (willingness to pay) placed by consumers on a public good such as endangered species. Sample consumers with characteristics X are asked whether they favor (with Y=1 if yes and zero otherwise) a referendum that would provide the good at a cost V specified by experimental design. This paper provides estimators for quantiles and conditional on X moments of W under both nonparametric and semiparametric specifications.     

Budget allocation for permanent and contingent capacity under stochastic demand

We develop a model of budget allocation for permanent and contingent workforce under stochastic demand. The level of permanent capacity is determined at the beginning of the horizon and is kept constant throughout, whereas the number of temporary workers to be hired must be decided in each period. Compared to existing budgeting models, this paper explicitly considers a budget constraint. Under the assumption of a restricted budget, the objective is to minimize capacity shortages. When over-expenditures are allowed, both budget deviations and shortage costs are to be minimized. The capacity shortage cost function is assumed to be either linear or quadratic with the amount of shortage, which corresponds to different market structures or different types of services. We thus examine four variants of the problem that we model and solve either approximately or to optimality when possible. A comprehensive experimental design is designed to analyze the behavior of our models when several levels of demand variability and parameter values are considered. The parameters consist of the initial budget level, the unit cost of temporary workers and the budget deviation penalty/reward rates. Varying these parameters produce several trade-offs between permanent and temporary workforce levels, and between capacity shortages and budget deviations. Numerical results also show that the quadratic cost function leads to smooth and moderate capacity shortages over the time periods, whereas all shortages are either avoided or accepted when the cost function is linear.     

The impact of the ‘Girls on the Move’ Leadership Programme on young female leaders’ self-esteem

Using findings obtained from an evaluation of the ‘Girls on the Move’ Leadership Programme in Scotland, this paper assesses the impact physical activity leadership courses and leading physical activities had on young women’s global self-esteem. While research has shown that engagement in youth development activities can contribute to an individual’s self-esteem, less is known about the impact of youth leadership on young people’s self-esteem. Based on pre-course and six-month follow-up surveys and using the Rosenberg self-esteem scale, it was found that increases in global self-esteem scores were highest in those that maintained an involvement in leading activities. The self-esteem of those attending training but not taking on leadership responsibilities remained largely unchanged. The findings indicate that youth leadership development has the power to make important contributions to the development of young people and youth development professionals should seek to provide meaningful leadership experiences for young people.     

美国风险收费制度对我国的启示

美国风险收费制度是根据案件的具体结果来支付律师费用的一种制度,案件胜诉则支付约定的费用,反之则不需或少付律师费用。虽然对于我国是否可采纳风险收费制度有不同的观点,但由于风险收费制度有利于解决我国目前面临的诉讼难的困境,以及对公益诉讼有不可低估的意义,因而在一定限度内采用应该是可行的。     

The Effect of Organization-Based Self-Esteem and Deindividuation in Protecting Personal Information Privacy

In this research we apply the Theory of Planned Behavior (TPB) to study decisions related to information privacy protection. A TPB-based model was proposed to investigate whether organization-based self-esteem and perceived deindividuation can be employed to measure the strength of the perceived behavioral control construct. In addition, we examined if the addition of a causal path linking subjective norms to attitudes and another causal path linking organization-based self-esteem to subjective norms enhanced our research model's predicting power. Our study shows that information systems (IS) professionals' intentions to protect personal information privacy are influenced by their attitudes, subjective norms, perceived deindividuation, and organization-based self-esteem. It further shows that attitudes are influenced by subjective norms, which, in turn, are influenced by organization-based self-esteem.     

On the range of options prices

In this paper we consider the valuation of an option with time to expiration and pay-off function which is a convex function (as is a European call option), and constant interest rate , in the case where the underlying model for stock prices is a purely discontinuous process (hence typically the model is incomplete). The main result is that, for “most” such models, the range of the values of the option, using all possible equivalent martingale measures for the valuation, is the interval , this interval being the biggest interval in which the values must lie, whatever model is used.     

Distribution-free estimation with interval-censored contingent valuation data: troubles with Turnbull?

Contingent valuation (CV) surveys frequently employ elicitation procedures that return interval-censored data on respondents’ willingness to pay (WTP). Almost without exception, CV practitioners have applied Turnbull’s self-consistent algorithm to such data in order to obtain nonparametric maximum likelihood (NPML) estimates of the WTP distribution. This paper documents two failings of Turnbull’s algorithm; (1) that it may not converge to NPML estimates and (2) that it may be very slow to converge. With regards to (1) we propose starting and stopping criteria for the algorithm that guarantee convergence to the NPML estimates. With regards to (2) we present a variety of alternative estimators and demonstrate, through Monte Carlo simulations, their performance advantages over Turnbull’s algorithm.

公益林生态效益价值居民支付意愿实证分析——以贵阳市为例

以贵阳市公益林为研究对象,采用条件价值评估法（CVM）,通过设计问卷、调查实施,对贵阳市居民公益林补偿的支付意愿（WTP）及影响因素进行了分析。结果显示：（1）73.6%贵阳市居民家庭对公益林生态效益价值有支付意愿,平均意愿支付额为每户家庭每年人民币213.96元;（2）支付意愿受社会经济因素综合影响,其中年龄、收入水平及环境关注态度对支付意愿具有显著影响,是影响支付意愿的主要因素。在对居民支付意愿影响因素进行分析的基础上,提出了一些建议性政策。     

基于CVM法评估石家庄世纪公园使用及服务价值

随着城市化进程的加快和城市人口的高度集中,城市公园的功能日益突出,但也易被改变用途。基于CVM调查法,调查评估石家庄世纪公园的使用状况及其服务价值。结果表明,(1)公园的辐射范围主要为30分钟的距离,游人以中年和老人为主;(2)运动是游客的主要活动类型,不同年龄段活动形式呈多样化、活动区域差异较大,林荫道为所有年龄段青睐;(3)公园的平均使用频率为9.5次/月,与收入水平无关,超八成游客对公园较为满意;(4)游人平均支付意愿为2.79元/人次,约占个人收入的0.8%,公园服务价值仅为土地出让最低价的四分之一。该研究可为城市公园的合理规划和管理提供参考和理论依据。
