Identifying Barriers to Self‐employment: The Development and Validation of the Barriers to Entrepreneurship Success Tool

ABSTRACT The present study sought to add to our knowledge about forces that negatively affect an individual's decision to start a business by identifying barriers they encounter. By identifying barriers to starting a business, we stand to learn much about how an individual identifies, confronts, and responds to decisions which may seem to be beyond their control. Such data will be instrumental in developing practical applications for helpingindividuals overcome unresolved barriers that potentially prevent them from starting a business. An instrument was developed utilizing factor analysis and yielded a six‐barrier construct. The barriers identified in this study were: lack of confidence, personal problems, lack of skills, start‐up logistics, financial needs and time constraints. In addition, the instrument was also administered to a test group of new entrepreneurs participating in a training program to determine pre‐ and post‐test intervention effects. The study concludes with suggestions for further development of the BEST tool as well as practical applications for program planners.     

速度的测不准关系和光速恒定原理

基于量子力学可以获得速度的测不准关系,这样光速作为速度也将是测不准的．在小时空范围和高能时,光速应有统计涨落．这些结果和真空中光速恒定原理存在矛盾．相对论和量子论只有在它们发展以后才能完全统一

An Experiment in Multinational Collaborative Learning and Group Work Using the Internet

In this paper we describe a pedagogic experiment, intended to support and encourage interactive group discussion among students from different universities, in different countries, in what we call Internet Seminars. In an Internet Seminar students and teachers cooperate via the Internet to research and discuss a common subject. In the case discussed here, the chosen subject, 'Teleworking' was selected as one which would have particular resonance with the medium of the seminar, and also as being a topic which is not, as yet, part of the mainstream teaching curriculum. The aims of the seminar, however, were not only or even primarily concerned with the subject material. We also hoped to encourage and help the students develop the transferable skills of project planning, research, team-working and communication, with the added stimulus of working in a multinational context. We describe the form of the seminar, report on its outcomes, and comment on the successes and failures of our approach. © 1999 IFIP, published by Kluwer Academic Publishers

Linking Science Education to the Workplace

This article examines the issue of linking education in the sciences with the world of work for all students. Traditionally, science teaching has been limited to preparing student for research career in science at the university level. The reform movement in science education is focused on intellectual skills that serve to fortify the human capital of all students and the economic productivity of the nation. The educational issue arises from evolutionary changes that are taking place in the practice of science, the development of a global economy, the nation's entrance into an Information Age, and the changing nature of the workplace. To identify and integrate these factors in the practice of science teaching is the goal of this article.
