Social entrepreneurship has emerged as an active area of practice and research within the last three decades. Nevertheless, in spite of its growing popularity, scholars and practitioners are far from reaching a consensus as to what social entrepreneurship actually means. This has resulted in a number of different definitions and approaches within the field of social entrepreneurship. The purpose of this article is to shed light on the ongoing contestation of social entrepreneurship and to offer a novel conceptual understanding of the concept that can facilitate the development of systematic and structured future research. To this end, we analyze social entrepreneurship on the basis of the theory of essentially contested concepts, which was proposed by Walter Bryce Gallie in 1956. Building upon this theory, this article shows that social entrepreneurship can be regarded as an essentially contested concept and that a universal definition that would be accepted among contestant parties is hardly possible. Responding to this recognition, the article proposes the conceptualization of social entrepreneurship as a cluster concept, which can serve as a conceptual tool to help advancing social entrepreneurship as a coherent field of research despite its contested nature. 相似文献

Despite extant literature, the most effective structure of loyalty programs is still heavily questioned among researchers. Building on the congruence principle, we examine the moderating role of brand concept. Our findings reveal that for symbolic brand concepts, customers perceive hierarchical loyalty program structures (which classify customers into tiers according to spending levels or other purchase activities) to be more congruent; this perception increases firm loyalty intentions. However, for functional brand concepts, customers perceive hierarchical and linear loyalty programs structures as equally congruent. Also for symbolic brand concepts, program structure appears as the most important feature in ensuring perceived congruence between a program and a brand, ahead of program benefits. These findings have important theoretical and managerial implications. 相似文献

由于500ml左右矿泉水瓶瓶口具有统一的螺纹规格,其次,瓶体的容量也具有接近统一的标准,这就为矿泉水瓶再生设计的开发提供了必要的前提。市场上关于矿泉水瓶的再生设计多利用矿泉水瓶作为盛水的容器,而没有继续探讨其盛放小型垃圾(瓜子壳,纸屑,铅笔屑等)的功能。本文以绿色设计中延长产品生命周期的理念为原则,以联想法、模仿法及组合法等产品设计方法为指导,推出一款全新的使用矿泉水瓶衍生功能的产品,并着重介绍在本设计进行的过程中得出的新的设计方法:系统化条件下的功能衍生法。通过这款设计来说明现有产品衍生出新的功能的可行性,并总结一定的设计经验与设计方法,为以后进行相关设计奠定理论和方法基础。 相似文献

This paper has a dual aim: (1) to outline the legal evolution of the ‘home base’ concept and (2) to map the role of this concept in determining the law applicable (both employment law and social security law) to employment contracts of European aircrew members. An in-depth analysis of the relevant portions of (1) Reg. (EEC) No 3922/91, (2) Reg. (EU) No 465/2012, (3) Reg. (EU) No 83/2014, (4) EASA's 2014 Certification Specifications, and (5) the European Court of Justice's preliminary ruling on joined cases C-168/16 and C-169/16 is conducted.What emerges is that (1) the ‘home base’ definition, due to its subjectivity, has traditionally been susceptible to multiple interpretations and (2) due to regulatory ambiguity, the use of ‘home base’ to identify the labour laws applicable to airline workers has for a long time been inconsistent, ranging from one extreme (being considered a key element for this purpose) to the other (being assigned a secondary role). It was only in the last few years that some improvements were made, with Reg. (EU) No 465/2012 first and the European Court of Justice's 2017 preliminary ruling then, clarifying that the ‘home base’ concept must be assigned a central role in the determination of the law (both social security law and employment law) applicable to employment contracts in the aviation industry. 相似文献

以具有大学生身份而在企业一线进行技能或操作型工作为培养目标的高职院校,应该特别重视引导学生形成健康的生活生存观念、完美的职业精神和良好的职业素养。因为在传统的价值观发生了颠覆性的断裂而孕育全新价值观的社会环境正在形成之中的社会、经济结构转型时期,学会认识、享受职业比掌握职业技能、选择职业更重要。 相似文献

近年来,过度劳动在我国呈快速上升趋势,而知识工作者正成为“过劳死”的高危群体.为了有效预防和干预知识工作者过度劳动导致的社会问题,有必要从理论上说明其影响因素和形成机制.本文根据经济学、管理学和心理学的相关理论,将影响因素划分为前因变量、决定变量和调节变量三类,构建过度劳动形成机制的概念模型,从知识工作者的群体特征和个体特质出发,分析各影响因素间的相互关系及其作用机理.总体而言,个人因素和管理因素对知识工作者的过度劳动动机、意愿和行为产生不同程度的直接影响,工作任务因素、社会文化、经济和制度层面等深层次原因构成的环境因素则激励或约束着知识工作者,使其在具备一定过度劳动动机和意愿的情况下,较其他劳动者更容易付出超强度的劳动强度和超长的劳动时间. 相似文献
