When age does not harm innovative behavior and perceptions of competence: Testing interdepartmental collaboration as a social buffer

Can older managers overcome stereotypes relating age to low competence? We integrate the literature on age and cognitive ability with research on innovation to explore whether—and if so, when—employees' age harms performance and promotability appraisals made by their supervisors. Multisource, time‐lag data from 305 project managers indicate that the negative stereotypes can be explained through decreased innovative behavior. However, older employees are not always seen as poorer performers with less potential to be promoted due to their reduced innovative behavior. Rather, interdepartmental collaboration moderates these effects. Specifically, older employees with low interdepartmental collaboration are less innovative and receive worse performance and promotability appraisals than younger employees, but the “age handicap” vanishes when older employees collaborate with members of other departments. Organizations should foster formal or informal collaboration among units to prevent negative consequences of an aging workforce.     

Consequences of a green image of drone food delivery services: The moderating role of gender and age

Drone food delivery services play a significant role in protecting the environment, because the services are operated by batteries that can be charged with electricity. Therefore, this study tried to examine a green image in the context of drone food delivery services. More specifically, this study proposed that a green image of drone food delivery services plays an important role in the formation of attitude toward using the services. In addition, it was hypothesized that the attitude has a positive influence on behavioral intentions including intentions to use, word‐of‐mouth intentions, and willingness to pay more. Lastly, the moderating role of gender and age was proposed during the theory‐building process. A theoretical model, which included 12 hypotheses, was developed and tested using a total of 427 samples collected in Korea. The data analysis results showed that a green image of drone food delivery services has a positive influence on attitude toward using the services, which in turn positively affects three subdimensions of behavioral intentions. Furthermore, gender and age played partly as a moderator. The current paper was the first to study the green image of drone food delivery services, so the findings of this study mean a lot to the theoretical aspect.     

我国经济发展水平与劳动力就业数量关系研究——兼论我国劳动力资源是否过剩

我国劳动力对经济发展而言，其生产率高于资本，因而经济发展对劳动力就业的促进作用逐渐减弱（经济增长的就业弹性逐渐变小）。据测算，我国2013年以前劳动力就业压力很大，2015年以后劳动力又会供不应求。所以，我国未来经济发展中，2014年前后应采用不同的产业结构调整策略来充分满足劳动力就业的要求。     

试论新时期大学生素质教育

目前，高等教育中“偏重知识传授，忽视能力和心理素质培养，影响了学生全面素质提高”的现象不同程度地造成了当前大学生在知识结构方面存在的问题，其突出的表现是：知识面狭窄，偏重专业知识，忽视人文、社会科学、经济、管理等学科，知识体系内部缺乏互补效应。加强和改进大学生素质教育，要遵循大学生素质教育规律和大学生成长成才规律，牢固树立“学校教育，育人为本，德智体美，德育为先”的思想，培养学生健全的人格和良好的心理素质。

试论"三言"、"二拍"中的商业智慧

明代中叶,随着资本主义的萌芽,商品经济空前繁荣,作为传统的"四民之末"的商人,纷纷登上历史舞台,充分展示了他们的聪明才智.冯梦龙的"三言"和凌濛初的"二拍"描写了许多成功的商人形象,艺术的再现了他们超群的商业智慧,他们审时度势,善抓商机,刻意经营,合理投资,勇于竞争,科学决策,凭自己的智慧赢得了商战的胜利.这些智慧,即使是在商品经济高度发展的今天,也还有着积极的借鉴意义.     

数字时代企业环境审计模式创新——基于环保政策响应机制的研究

企业规避环保责任的机会主义行为导致政府环保政策成效不显著。基于利益相关者理论构建环保政策利益相关者模型,并从环保权力、责任和信息三个角度分析企业的环保政策响应机制。研究发现：由于消费者缺位以及信息不对称等因素的影响,企业的环保政策响应水平较弱。政府应将环保政策施加于消费者,通过消费者来约束企业的行为;审计主体应当转变现有的审计模式,运用数字技术,与消费者合作共同完成审计监督的工作。基于此,提出一种基于消费者需求引导的综合环保政策及新型企业环境审计模式,建议政府应重视数字技术对产业的改造升级,充分考虑消费者的因素来制定环保政策并加大对企业污染数据实时监控的普及。     

Killing off cohorts: Forecasting mortality of non-extinct cohorts with the penalized composite link model

Mortality forecasting has crucial implications for insurance and pension policies. A large amount of literature has proposed models to forecast mortality using cross-sectional (period) data instead of longitudinal (cohort) data. As a consequence, decisions are generally based on period life tables and summary measures such as period life expectancy, which reflect hypothetical mortality rather than the mortality actually experienced by a cohort. This study introduces a novel method to forecast cohort mortality and the cohort life expectancy of non-extinct cohorts. The intent is to complete the mortality profile of cohorts born up to 1960. The proposed method is based on the penalized composite link model for ungrouping data. The performance of the method is investigated using cohort mortality data retrieved from the Human Mortality Database for England & Wales, Sweden, and Switzerland for male and female populations.

陕南汉江走廊新石器时代考古聚落研究

陕南汉江走廊地区新石器时代的聚落遗址基本上分布在汉江及其主要支流所形成的平原台地和河谷阶地上。根据聚落的选址特点，可以将区域内的聚落分为平原台地型和河谷阶地型两种。文章以考古发掘资料为主要依据对这一区域内聚落的地理环境进行了微观个案研究。由于所处的地理环境不同，聚落规模和文化层的堆积都有差别，聚落中居民的生产方式也不一样。这种比较研究充分阐述了新石器时代走廊内的人地关系。
