Business models for sustainable technologies: Exploring business model evolution in the case of electric vehicles     

René Bohnsack  Jonatan Pinkse  Ans Kolk 《Research Policy》2014

Sustainable technologies challenge prevailing business practices, especially in industries that depend heavily on the use of fossil fuels. Firms are therefore in need of business models that transform the specific characteristics of sustainable technologies into new ways to create economic value and overcome the barriers that stand in the way of their market penetration. A key issue is the respective impact of incumbent and entrepreneurial firms’ path-dependent behaviour on the development of such new business models. Embedded in the literature on business models, this paper explores how incumbent and entrepreneurial firms’ path dependencies have affected the evolution of business models for electric vehicles. Based on a qualitative analysis of electric vehicle projects of key industry players over a five-year period (2006–2010), the paper identifies four business model archetypes and traces their evolution over time. Findings suggest that incumbent and entrepreneurial firms approach business model innovation in distinctive ways. Business model evolution shows a series of incremental changes that introduce service-based components, which were initially developed by entrepreneurial firms, to the product. Over time there seems to be some convergence in the business models of incumbents and entrepreneurs in the direction of delivering economy multi-purpose vehicles.  相似文献   

论预备警察职业素养的培育模式--以加强人文素质教育为中心视角     

范瑛 《科教文汇》2014,(32):64-65

公安院校不仅仅是培养预备警察的摇篮,同时也是培育“莘莘学子”、人文荟萃的高等学府。公安院校唯有把科学精神和人文精神有效结合起来,才能给预备警察一个光明的未来。因此,公安院校要增强其文化底蕴,多层次、全方位地推进预备警察的人文素质教育,而且还要有计划、分步骤地组织预备警察深入基层公安业务实践,通过这种广泛深入社会的实践锻炼去历练和拓展其人文素质的内涵与深度。  相似文献

Inclusive Pedagogy in Light of Social Justice. Special Educational Rights and Inclusive Classrooms: on whose terms? A Field Study in Stockholm Suburbs     

Nilani Ljunggren De Silva 《European Journal of Education》2013,48(3):419-435

The question of inclusive education is not straightforward. Despite all its good intentions, inclusive education, in practice faces numerous challenges today. This study analyses these challenges in the Swedish special education context. The author explores special educators’ experiences, possibilities and challenges when applying inclusive education. Findings reveal positive attitudes to the concept of inclusive classrooms. Nevertheless, teachers face more than a few grey areas that need to be put in place in order to achieve socially and cognitively inclusive classrooms.  相似文献   

Obtaining Diagnostic Classification Model Estimates Using Mplus     

Jonathan Templin  Lesa Hoffman 《Educational Measurement》2013,32(2):37-50

Diagnostic classification models (aka cognitive or skills diagnosis models) have shown great promise for evaluating mastery on a multidimensional profile of skills as assessed through examinee responses, but continued development and application of these models has been hindered by a lack of readily available software. In this article we demonstrate how diagnostic classification models may be estimated as confirmatory latent class models using Mplus, thus bridging the gap between the technical presentation of these models and their practical use for assessment in research and applied settings. Using a sample English test of three grammatical skills, we describe how diagnostic classification models can be phrased as latent class models within Mplus and how to obtain the syntax and output needed for estimation and interpretation of the model parameters. We also have written a freely available SAS program that can be used to automatically generate the Mplus syntax. We hope this work will ultimately result in greater access to diagnostic classification models throughout the testing community, from researchers to practitioners.  相似文献

汉英思维模式差异视角里的《英语课程标准》     

陈万生 《天水师范学院学报》2004,24(3):92-95

语言是思维的外衣,思维影响语言。汉英思维模式差异不仅导致语言结构的不同,而且影响教学观念、教学模式的形成。受汉民族思维模式支配的我国传统英语教学忽视学习主体,效果不佳。《英语课程标准》坚持以人为本,面向全体的价值取向,开辟了有效的英语教学新途径。  相似文献
