Investment model predictions of workplace ostracism on K–12 teachers’ commitment to their schools and the profession of teaching

The purpose of this study was to determine how the ostracism of K-12 teachers influences their commitment to their schools and commitment to the teaching profession. The investment model was used to situate ostracism as a predictor of teacher commitment. Participants were 200 full-time K-12 teachers who completed a survey assessing their experiences with ostracism at work and investment model variables (i.e., investments, quality of alternatives, satisfaction, and commitment). Results confirmed investment model predictions with teachers’ investments, quality of alternatives, and satisfaction predicting their commitment to their schools and profession. Results of mediation models also demonstrated that controlling for teachers’ investments and quality of alternatives, ostracism predicted commitment indirectly through its effect on satisfaction. This study revealed that teacher commitment is explained by investment model predictions, but after controlling for those predictions, is further explained by ostracism from teacher colleagues.     

SROI in the pay for success context: Are they at odds?

The Pay For Success (PFS) and Social Impact Bond (SIB) movements to date have focused heavily on shorter-term outcomes that can be monetized and show clear savings to government entities. In part, this focus derives from the need to specify contract payments based on a narrow set of well measured outcomes (e.g., avoided days in jail and foster care, decreased use of behavioral health services). Meanwhile efforts to measure the social return on investment (SROI) of interventions have sought to expand the view of relevant outcomes to include domains that lend themselves less clearly to monetization. This paper explores the intersection between these two movements with illustrations from a SIB initiative underway focused on homeless families with children in foster care. Challenges and potential for SROI in a third-party payor environment will be discussed as well as opportunities to better leverage the strengths of both types of initiative.     

Investor commitment to serial entrepreneurs: A multilayer network analysis

Social networks are complex systems composed of interdependent organizations and people with diverse network structures. Understanding network dynamics, such as exchange commitment, requires a methodological toolkit that does not assume away complexity. In this study, we extend a technique for analyzing longitudinal, multilayer network data called network alignment. We introduce a novel metric – intersect proportions – for analyzing similarity between divergent graphs. We demonstrate the application of network alignment and intersect proportions to the context of investor commitment to startups and entrepreneurs. Using this technique, we are able to disentangle exchange commitment across complex networks.

IT投资转化为企业生产率的影响因素研究

关于"IT投资是否能提高企业生产率"这一命题,学界一直众说纷纭,一个很重要的原因在于这些研究建立在IT投资能对企业生产率产生直接影响的假设前提之上,而忽略了IT作用于企业生产率的中间过程。IT投资必须与企业内部生产环境相吻合才能提高企业生产率,IT投资转化为企业生产率的影响因素包括内部因素和外部因素,其中内部因素包括企业管理特征、企业员工特征及企业结构特征;外部因素指的是企业所面临的外部环境。     

深圳市投资率与投资效益的合理区间分析

投资、消费和净出口被喻为拉动经济发展的三驾马车。对于深圳这样一个以投资拉动为主的城市,投资在经济发展中具有重要的地位。通过对投资率和ICOR的国际比较分析,综合深圳市发展的历史阶段,可以揭示并发现深圳市的投资率与ICOR的合理区间、正确规划,以及深圳市的长远发展目标和规划。     

房地产开发项目三阶段投资决策的实物期权模型研究

房地产开发项目一般包括土地所有权的获得、建筑和销售三个阶段,对于其投资决策,传统的NPV法无法正确地评价管理的柔性价值。文章引入实物期权理论,指出实物期权是对实物投资的选择权,对于房地产开发项目,当每一阶段完成后,即拥有了对后续阶段的投资期权。针对企业投资房地产开发项目的三阶段决策建立了相应的实物期权模型,并给出了每一阶段的期权价值以及最佳投资点的临界价格。     

外商直接投资对广东地区收入差距的影响探析

外商直接投资（FDI）是区域经济增长的重要动力。FDI区域分布差异,是造成区域收入差距悬殊的重要原因之一。文章经验和实证分析相结合,深入探讨了FDI与广东区域经济发展和收入差距扩大的互动,认为FDI区域分布失衡是造成广东区域经济发展和收入差距扩大的重要原因。新形势下,广东要实现区域经济协调发展,有效解决区域发展和收入差距悬殊问题,须加快发达地区外资劳动密集型企业升级转型和欠发达地区的招商引资步伐,实现外商投资的均衡布局和优化发展。     

浅析房地产市场复苏的制约因素及其对策

房地产市场包括一级市场和二级市场，二级市场又包括消费市场和投资市场。现在的政策导向只注重房地产消费市场部分，而忽视了其投资市场部分，这是潜力巨大的市场。房地产只有真正成为大众投资品种时，才可能促进房地产一、二级市场的共同繁荣
