The role of institutional entrepreneurship in building digital ecosystem: A case study of Red Collar Group (RCG)

Institutional entrepreneurship has increasingly played a critical role in successfully achieving organizational transformation, especially one that involves building a digitally enabled ecosystem. However, despite fruitful research on institutional entrepreneurship, it is still not clearly understood how one might successfully achieve organizational transformation. Thus, our study aims to disambiguate this black box by examining the case study of Red Collar Group (RCG), a market leader in making custom made suits. The findings of this case highlight the significant role played by institutional entrepreneurship in achieving organizational transformation. It highlights that institutional entrepreneurship is evident in different modes of action in the transformational process of building the digital ecosystem.

从人权和有效参与视角来理解少数民族自治

《隆德建议书》是欧共体为少数民族有效参与公共生活制定的纲领性献，它所建议的制度与我国的民族区域自治制度非常相近。与之相比，我国的民族区域自治制度注重少数民族的自治权，立足于我国民族关系和政治特点，关注自治地方实体权利及其实现，侧重于中央与民族自治地方关系的解决；建议书则注重少数民族有效参与公共生活，立足于国际标准，关注程序的设计和安排，侧重所有人人权的保护少数民族权利的民主法治环境。了解建议书，对我们深入理解少数民族自治，完善和发展我国的民族区域自治理论有一定的意义。     

点击流数据仓库构建个性化信息服务

随着计算机技术的发展,信息服务已经遍布各行各业,而且随着服务的纵深,个性化的服务方式也越来越流行。如何根据用户的行为习惯和需求,为其量身定制一些服务是考核个性化信息服务水平的重要参数。文章将讨论如何通过点击流数据仓库来构建个性化信息服务。     

基于序列模式的个性化Web页面推荐模型*

基于数据挖掘中的序列模式方法,提出一种个性化Web页面推荐模型。该模型首先利用Web使用数据预处理提取Web交易事务集,然后应用序列模式算法挖掘频繁（连续）序列,最后通过构建频繁（连续）序列树生成用户偏好视图以生成个性化Web页面推荐集。     

基于情景模型的数字图书馆个性化服务研究

由于web环境下用户的个性化需求具有易变性、动态性和情景敏感性等特征,个性化服务的提供越来越需要情景模型的支持.目前,基于情景模型的数字图书馆个性化服务主要通过个性化检索和个性化推荐两种方式实现.将情景模型运用于数字图书馆个性化服务,还需要注意和解决用户情景捕捉的准确性、服务提供的适用性、用户安全与隐私、用户模型与情景模型的结合以及数字图书馆各种资源的整合与集成等问题.图3.

Strengths-based blended personalized learning: An impact study using virtual comparison group

Abstract

This study describes a strengths-based blended personalized learning model, the implementation of the model over a 4-year period, and the results of an impact study focused on measuring its effectiveness. The model includes many commonly-used features of personalized learning, including (a) competency-based progressions, (b) flexible learning environments, (c) personal learning paths, (d) frequently updated student profiles, and (e) frequent informal and formal measurement. However, it differs from other personalized learning models by including a focus on strengths-based learning. Strengths-based learning identifies and builds upon students’ strengths, supporting their ability to make informed decisions when setting goals and choosing and implementing learning experiences. The longitudinal study took place in a diverse mid-size pre-K to Grade 8 school district in California. The findings suggest that the strengths-based blended personalized learning model is effective in supporting student learning in the academic areas of mathematics, reading, and language usage. Over the 3-year period in which the intervention was gradually implemented, and one year of full implementation, students significantly outpaced their matched student counterparts in all subject areas. The results of the current study further the growing literature in the field of personalized learning by contributing learnings and evidence related to a successful personalized learning model.
