研究了由一制造商及一经销商构成的闭环供应链系统,其中制造商具有公平关切心理特性并通过专利费授权经销商进行再制造.建立并求解了分散、集中两种决策模型并用收益费用共享机制进行了供应链协调。研究表明:制造商的公平关切特性能增强议价能力,但不利于社会绿色效应的提高;集中决策下的产品零售价、废品回收价均低于分散决策,而销售量、废品回收量及供应链效用高于分散决策;该类供应链只能实现效用的帕累托改进而无法完全协调。  相似文献

With the increasing concern about the high attrition rate among beginning teachers, it is essential that we come to a better understanding of why teachers leave the profession. This study explored differences between leavers and stayers in terms of the process of their resilience responses. Major psychological factors such as value, self-efficacy, beliefs and emotions were foregrounded to understand how leavers and stayers are similar or different in negotiating and interpreting external environments. This study employed semi-structured interviews for seven leavers and seven stayers who had teaching experiences of less than five years. The findings of this study showed that both leavers and stayers had intrinsic interests in working as a teacher. Also, both groups identified similar challenges of working as a teacher, such as classroom management and effective delivery of lessons. However, leavers showed weaker self-efficacy beliefs than stayers, who tended to get more support and help from school administrators. In addition, leavers held beliefs that imposed heavy burdens on themselves, which may have created stress and emotional burnout. Unlike leavers, stayers often reported their strategies to prevent them from being burned out by setting boundaries establishing relationship with students. Given the high attrition rate of beginning teachers, the current study provides meaningful insight about challenges beginning teachers’ face, their needs and better ways to prepare and train them.  相似文献

ABSTRACT

Teachers’ concerns have been regarded as one of the key variables closely associated with successful implementation of innovative educational changes. China has initiated educational reform toward inclusive education since 1980s. Research related to inclusive education is very limited and teachers’ concerns remain unclear and are seldom investigated. The purpose of this study is to investigate the levels of Chinese regular education teachers’ concerns towards inclusive education by utilising Concerns-Based Adoption Model as a framework. The Stages of Concern Questionnaire was refined to conform to the Chinese educational context and administered for data collection in Beijing from a sample of 425 regular education teachers. The result indicates that regular education teachers make decisions on whether or not to implement inclusive education based on what they know about inclusive education and how effective it is to be. Regular education teachers demonstrate a ‘Multiple Peak User Profile’ in the Stages of Concern model, and that their concerns vary according to a few demographic factors. The results inform educational leaders’ decision making in improving programmes for teachers’ professional development for inclusion.  相似文献

与现实生活中的朋友关系不同,多数的在线社交网络系统为每个人只设定一个简单的二元好友联系,即要么是朋友,要么不是。这种好友关系的定义为个人隐私信息的保护带来了许多问题。分析了一种基于当前社交网络平台的互动信息自动判定好友亲密度方法,并结合该方法提出了一种半自动的隐私控制框架。  相似文献

Abstract

Just as the introduction of advanced information technologies—computers, telecommunications, microform systems, video and audio devices—into the realms of business, agriculture, education, various social services, and science has had a decided impact on those vital activities, so are these “tools” and their related methodologies having an effect on emergency management. The growing complexity of our society is necessitating changes in many institutions and processes, and nowhere is this more apparent than in the four phases of emergency management: mitigation, preparedness, response, and recovery. One approach to enhancing governmental preparedness, both at the federal and state‐local levels, is through the selective utilization of devices and networks which facilitate and improve the collection, storage, processing, and dissemination of information vital to those who must anticipate and cope with a range of disasters.  相似文献

With the ever-increasing collection of user data, online privacy becomes an urgent matter for users and research across borders. The perception of information sensitivity is central to privacy attitudes and behaviors in different usage contexts. In an online questionnaire, n = 592 German internet users evaluated how sensitive they perceive 40 different data types. The German sensitivity evaluations revealed in this study are compared to results from the US and Brazil (Markos et al., 2017), in order to understand the cultural impact on evaluations. Additionally, we analyze how attitudes and demographic characteristics of the German sample influence the perception of sensitivity on an individual level. Some distinct differences in sensitivity perception between Germany, Brazil, and the US can be observed, but the rank orders of sensitivity of data types is very similar between the countries, indicating that there is a consensus on what constitutes sensitivity across nations. On an individual level, disposition to value privacy, risk propensity, and education level influence the perception of sensitivity. The findings contribute to an understanding of how to design information and communication strategies to inform internet users how to manage their data carefully.  相似文献
