This paper examines information access in Nepal, its current limitations, and opportunities for expansion, particularly in rural areas. It argues that government policies and the regulatory environment have failed to create the competition necessary for rapid expansion of information access through information and communication technologies (ICTs), particularly in rural areas. Furthermore, restrictive approaches to licensing and exorbitant fees have hindered the ability of civil society organizations, non-governmental organizations (NGOs), and small and medium enterprises (SMEs) to provide information access at the local level. This has resulted in very limited access to information outside a few urban centers and created some of the world's highest access costs in one of its poorest countries. To successfully address this situation, the newly installed republican government will need to create an environment that promotes competition in less lucrative rural markets while negotiating the demands of existing license holders. 相似文献

The landscape has long been an important object of rural policy, particularly in terms of protecting scenic areas. Increasingly, however, landscape is seen as a multifunctional and holistic entity, which provides a framework for the governance and interdisciplinary study of spatial units. A central dilemma in the maintenance of cultural landscapes is that the historical practices which produced them are often obsolete, and new social and economic forces may fail to reproduce their valued properties. Sustainable development strategies therefore seek to instil ‘virtuous’ circles in cultural landscapes, linking society and economy to environmental service functions and land uses, in order to generate mutually reinforcing feedback loops resulting in socially preferred outcomes. We explore ways of investigating these linkages as a basis for future rural research and policy. We conceptualise cultural landscapes as ‘socio‐ecological systems’ (SESs), and consider their capacity for resilience and stability. Noting that resilient systems are characterised, not by simple equilibria, but by ‘basins of attraction’, we argue the need to understand the ways in which SESs stabilise within a particular basin, or move to an alternative. In particular, we reflect on the dynamics of ‘adaptive cycles’ that may lead to changes in system state. Finally, we discuss the development of appropriate models as tools for investigating whether a landscape is trending towards stability within a ‘vicious’ or a ‘virtuous’ circle, and evaluating potential interventions to alter this trajectory. 相似文献

After working with hundreds of leaders in a wide variety of organizations and in countries all over the globe, the authors found one very clear pattern: When it comes to meeting their leadership potential, many people unintentionally get in their own way. Five barriers in particular tend to keep promising managers from becoming exceptional leaders: People overemphasize personal goals, protect their public image, turn their competitors into two-dimensional enemies, go it alone instead of soliciting support and advice, and wait for permission to lead. Troy, a customer service manager, endangered his job and his company's reputation by focusing on protecting his position, not helping his team; when a trusted friend advised him to change his behavior, the results were striking. Anita's insistence on sticking to the tough personal she'd created for herself caused her to ignore the more intuitive part of the leadership equation, with disastrous results--until she let go of the need to appear invulnerable and reached out to another manager. Jon, a personal trainer who had virtually no experience with either youth development programs or urban life, opened a highly successful gym for inner-city kids at risk; he refused to be daunted by his lack of expertise and decided to simply "go for it." As these and other examples from the authors' research demonstrate, being a leader means making an active decision to lead. Only then will the workforce--and society--benefit from the enormous amount of talent currently sitting on the bench. 相似文献

The main purpose of this paper is to study the intraday return spillovers and their real time variations amongst selected
technology stocks. Based upon randomly selected technology stocks in terms of multilateral analysis, we find the following
evidence. Firstly, we find that positive spillover effects are discernible amongst medium- and large-sized stocks, with the
effects being directionally asymmetric between different size groups. Secondly, we find that for most stocks, the full effects
of the firm-specific shocks over other stocks are realized within approximately 30 min to 2 h. Finally, we show that the spillover
effects tend to follow an M-shaped intraday pattern. Our results suggest that during the opening and closing sessions, trades
motivated by information spilled over from other firms are relatively subordinated, with the trading at these times being
largely dominated by those based upon common market factor or firm-specific fundamental information. 相似文献

In what size consumer markets does the consumer fare best — those of large, medium-sized, or small cities/towns? This is the general question that this article seeks to answer through analysis of price-quality data pertaining to Minneapolis (a large city), Ann Arbor, MI, and Ithaca, NY (a small town). While differences were smaller than expected, limited evidence from this pilot study support the notion that small markets are most efficient. At the same time the analysis confirms others' findings that most consumer markets are chaotic. 相似文献

Recent work has shown the prevalence of monopsony power in labor markets characterized by low pay. Monopsony has long been offered as a potential explanation of labor market discrimination. Yet, in the case of gender discrimination, most studies suggest that female labor supply is more elastic than that of males which, in a standard monopsony model, would imply higher pay for females. In the current paper we develop a theoretical framework capable of reconciling these empirical phenomena. We also attempt to explain: (i) the puzzle regarding the apparent trade-off between profits and discrimination in the standard neoclassical treatment of discrimination associated with the work of Becker (1957) and Arrow (1973) and (ii) the apparently paradoxical increase in female relative employment at a time of a significant rise in the relative price of female labor. 相似文献

Capital asset pricing model (CAPM) and alternative arbitrage pricing theory (APT) methodologies are used to estimate the cost of capital for a sample of electric utilities. The statistical factors APT method is found to produce significantly different estimates depending on the number of factors specified and the set of firms factor analyzed. The use of macroeconomic factors is explored, and it is shown that this methodology has advantages over the statistical factors APT and the market model. 相似文献

Robin Jacobs and Robert Bolton argue that, although competency-based assessment methods have improved the haphazard management development practices of the past, they nonetheless provide an incomplete picture for improving performance and developing potential. They suggest that self-development through a career planning framework might provide the missing link and present a case study in this area based on their work in the Nationwide Building Society. Robin Jacobs is a Lecturer in Management at the Open University Business School as well as one of the directors of Transitions Limited, and Robert Bolton is Human Resources Manager at the Nationwide Building Society. 相似文献

The computing occupations are in a state of transition between a technical service and something more central to organizational power and decision-making. This process has had complex implications for the nature of computing work and for careers. There is no certainty that embryonic changes will carry through. But neither should the chances of these occupations of mounting a 'collective mobility project' be written off early. 相似文献
