The first wave of revival of States and nations of Asia and Africa which shaped major changes in the history of humankind organized itself in the Bandung spirit in the frame of countries Non-Aligned on colonialism and neo colonialism, the pattern of globalization at that time. Now, the same nations, as well as those of Latin America and the Caribbean, are challenged by neo-liberal globalization, which is no less imbalanced by nature. Therefore, they must unite to face the challenge successfully as they did in the past. In some countries “sovereign” projects are developed that associate active State policies aimed at systematically constructing a national integrated consistent modern industrial productive system, supported by an aggressive export capacity. Views with respect to the degree, format and eventual regulation of opening to foreign capital and financial flows of all kinds (foreign direct investments, portfolio investments, speculative financial investments) differ from country to country. Policies pursued with respect to the access to land and other natural resources also offer a wide spectrum of different choices and priorities.  相似文献

Despite several studies having been conducted to examine organizational image from a business perspective, there has not been adequate research in the area of perceived image in nonprofit organizations such as universities. Thus, the purpose of this study was to examine the factors contributing to university image, from the postgraduate students’ point of view. In addition, the impact of the students’ perceived university image on their organizational trust was examined. The population of this study consisted of postgraduate students in 10 of the top Iranian universities. Questionnaires were used to collect the required data. The findings indicated the difference between current practices and ideal values of the factors contributing to the university image. Based on our findings, the factors contributing to university image range from internal and international reputation, university members, and academic planning, to university environment. Furthermore, we found that university image has a significant impact on students’ trust in their university.  相似文献

Having found hidden hyperchaos in a 5D self-exciting homopolar disc dynamo, we study the existence of a Hopf bifurcation, which leads to unstable limit cycles bifurcating from a stable equilibrium. Hidden chaos with only stable equilibria can be observed from the Hopf bifurcation: a typical way to enable hidden attractors to be located. We then provide a new fuzzy controller, and a fast fuzzy disturbance observer, based on terminal sliding mode control for synchronization of the hyperchaotic system. Fuzzy inference is considered to weaken the chattering phenomena. Using Lyapunov stability theory, the stability of the closed-loop system is proved. Finally, simulations of synchronization are illustrated to show the efficient performance of the designed control method via external disturbances and dynamic uncertainties.  相似文献

Mentoring programmes have gained increasing popularity in institutions of higher education to support undergraduates in community service or outreach efforts. Many of these programmes partner mentors with inner‐city youth, providing assistance in underserved communities while mentors gain experiences that connect theory and practice. Here we report on two years of fieldwork in a Community Technology Centre that created mentoring partnerships in which 36 liberal arts undergraduates engaged with local youth to design, create, and build technology projects involving graphics, video, music, and animation. We analysed over 200 field notes, which described their mentoring interactions over eight weeks and conducted exit interviews about their mentoring experiences. Our results indicate that mentors participated not just as more knowledgeable peers but also as facilitators, advisors, observers and, most importantly, as learners in this process. In the interviews, nearly all mentors reviewed assumptions about their own learning and mentoring, in addition to reflections about social issues. We discuss the importance of these findings for conceptualising mentoring as a partnership by creating more equitable interactions in service learning initiatives. We also address the role of constructionist activities in facilitating learning opportunities for both mentors and mentees.  相似文献

ABSTRACT

This article reports on issues of diversity in the context of widening participation in global higher education (HE). Mature students represent a third of the HE student population in Australia, Canada, UK and the USA. More research is needed to understand factors that can facilitate or hinder access to HE for this group. The aim of this study was to examine factors that a small group of mature students perceived influenced them as they made the decision to take up HE. Six undergraduate students at a British university who were on track to finish their studies took part in semi-structured interviews. All participants were white and from families with no previous experience of HE. Mean age was 42.7 years (range 35–51), and 50% were female. The interviews were analysed using Interpretative Phenomenological Analysis. Through using phenomenological analysis to analyse perceptions of changing motivation and goals during the decision-making process to take up HE, a detailed understanding of the complexity of these change processes was obtained. The analysis offers evidence that mature students experience far-reaching personal and social changes related to their decision to enter HE and adds a novel understanding of these identity-changes. This new insight is of fundamental importance to the field because the novel understanding of mature students’ meaning-making could be used to tailor interventions to facilitate access to HE for mature students.  相似文献
