An increase of broadband demand is forecasted by transitional methods that consider the effect of this increase through many
factors, such as customer requirement diversification, and new service introduction and deployment under competition. Broadband
demand forecasting has become important for closing the digital divide, promoting regional developments, and constructing
networks economically; therefore, a demand forecast model that considers the mechanisms of market structure is necessary.
In this paper, a demand analysis method for broadband access combining macro- and micro-data mining is proposed, and the service
choice behaviour of customers is introduced as a customer model not only to express the macro trend of market structure, but
also to consider area marketing. The proposed method can estimate the potential demand, determine the point at which broadband
demand growth peaks in a specified area, and support a decision for ultra high-speed broadband access facility installation. 相似文献

The mechanisms used to deliver agricultural beneficial management practices (BMPs) can influence the performance of these policies. Research has suggested that agri‐environmental instruments targeted based on specific economic or environmental characteristics can improve policy performance. Using a case study approach, we evaluate the relative performance of different mechanisms to target subsidized water retention pond BMPs to reduce phosphorus (P) runoff in an agriculture dominated subwatershed within the Lake Winnipeg watershed in southern Manitoba. The water retention pond BMPs were targeted based on estimated establishment costs (cost targeting), total phosphorus removal from surface water (benefit targeting), and pond‐specific benefit–cost ratios. The targeting was simulated using predictions of retention pond‐specific P removal from an adapted hydrology model and site‐specific pond construction and land opportunity costs assembled in a geographic information system database. Targeting of water retention pond BMPs has an impact on the cost effectiveness of the policy delivery with benefit–cost targeting being the most cost‐effective approach. Water retention ponds providing higher P removal at lower cost were smaller in size and on land previously used for the production of lower value crops. Le ciblage économique des pratiques de gestion bénéfiques en agriculture pour remédier au ruissellement du phosphore au Manitoba Les mécanismes utilisés pour livrer des pratiques de gestion bénéfiques (PGB) peuvent influencer la performance de ces politiques. Des études suggèrent que le ciblage d'instruments agroenvironnementaux basé sur des caractéristiques économiques ou environnementales précises peut améliorer la performance des politiques. Au moyen d'études de cas, nous évaluons la performance relative de divers mécanismes pour cibler les PGB des bassins de rétention d'eau subventionnés pour réduire le ruissellement de phosphore (P) dans un sous‐bassin du bassin du Lac Winnipeg au sud du Manitoba. Les PGB du bassin de rétention des eaux ont été ciblées en fonction des coûts estimés d'établissement (ciblage des coûts), de l′élimination totale du phosphore de la surface de l'eau (ciblage des bénéfices), et des ratios avantages‐coûts liés au bassin. Le ciblage fut simulé au moyen de prédictions du taux de suppression de P spécifique à chaque bassin de rétention obtenues à partir d'une adaptation d'un modèle hydrologique et d'une base de données d'un système d'information géographique (SIG) contenant les sites de chaque bassin de rétention et le coût d'opportunité du terrain. Le ciblage des PGB des bassins de rétention d'eau a un impact sur la rentabilité de la mise en ?uvre de politiques, le ciblage coût‐avantages étant l'approche la plus rentable. Les bassins de rétention d'eau ayant le plus haut taux d'élimination de P à moindre coût s'avéraient plus petits et sur des terrains ayant servi, auparavant, à la production de cultures de moindre valeur. 相似文献

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus. 相似文献

Abstract In this article we investigate three related investment-consumption problems for a risk-averse investor: (1) an investment-only problem that involves utility from only terminal wealth, (2) an investment-consumption problem that involves utility from only consumption, and (3) an extended investment-consumption problem that involves utility from both consumption and terminal wealth. Although these problems have been studied quite extensively in continuous-time frameworks, we focus on discrete time. Our contributions are (1) to model these investmentconsumption problems using a discrete model that incorporates the environment risk and mortality risk, in addition to the market risk that is typically considered, and (2) to derive explicit expressions of the optimal investment-consumption strategies to these modeled problems. Furthermore, economic implications of our results are presented. It is reassuring that many of our findings are consistent with the well-known results from the continuous-time models, even though our models have the additional features of modeling the environment uncertainty and the uncertain exit time. 相似文献

There has been considerable research on the issues of board-level representation by personnel/HR directors and senior HR managers' involvement in strategic decision making. Since the early 1990s there has been a growing interest in international HRM, reflecting the growing recognition that the effective management of human resources internationally is a major determinant of success or failure in international business. There is also evidence that HR constraints often limit the effective implementation of international business strategies. More recently, it has been argued that the more rapid pace of internationalization and globalization leads to a more strategic role for HRM as well as changes in the content of HRM. Yet, while there have been some attempts to integrate international corporate strategy and human resource strategy, surprisingly, the role of the corporate human resources function has been neglected, particularly in the context of the international firm. This article seeks to redress the balance. The question addressed is: what is the role of the corporate HR function in the international firm? To answer these questions empirical research was conducted in thirty UK international firms. We found an emerging agenda for corporate HR in international firms which focuses on senior management development, succession planning and developing a cadre of international managers. We conceptualize this as a strategic concern with developing the core management competences of the organization, and argue that it can be usefully analysed from the perspective of the learning organization. 相似文献

This paper broadly explores changing outdoor recreation demands, environmental opinions and demographics in the United States. With this country's population predicted to more than double by the end of this century, it is imperative that we understand these trends and their implications for better managing our natural environment and providing opportunities for outdoor recreation in that environment. Using national survey data, we have described differences in recreation behavior (participation) and environmental attitudes nationwide across six socio-demographic factors-race, country of birth, rural-urban residence, region of the country, age and income. Results indicate that demographic differences, recreation activity choices and people's environmental positions are linked. 相似文献

This study is an attempt to develop a scale to measure expectations of buyer–seller working relationships on a cross-cultural basis in the hospitality industry. The focus is on North American and Asian hotel salespeople. The scale development drew from previous research in guanxi relationships, purchasing, and selling strategies. While the results did not support a reliable unidimensional scale that could distinguish between transactional and collaborative working relationships, the methodology did create a framework for further scale development. 相似文献

In recent years, below‐the‐line promotion has begun to shed its “Cinderella” image, and is starting to attract the sort of marketing budgets and academic attention that was previously only given to mass‐media advertising. However, there is a general consensus that sales promotion is still neither managed effectively, nor understood thoroughly when compared to more high‐profile above‐the‐line promotion. Improving the understanding and use of sales promotion will require academics and practitioners to analyse and understand each of the very different below‐the‐line techniques and their individual merits. This article is one of two which takes a detailed look at the use of sales promotion competitions. 相似文献

Institutionalism was the dominant approach to public finance prior to WWII, after which it was eclipsed by Pigouvianism and Keynesianism. This transition defined the career of Wisconsin’s Harold M. Groves (1897–1969). Groves was a notable public finance economist, leading textbook author, and drafter of significant tax and labor legislation. He represented the culmination of a multigenerational institutionalist tradition. In this paper, I examine Groves and postwar public finance as a test case for the legacy of Wisconsin institutionalism. To that end, I consider Groves’s contributions to postwar tax policy, his interactions with Henry C. Simons and Richard M. Musgrave, and his view on Keynesian public finance. I identify some Wisconsin institutionalist contributions to modern public finance and offer an explanation for the postwar decline in institutional public finance. 相似文献

This paper is concerned with the role of stakeholder driven strategic planning as a contributor to the ultimate sustainability of tourism development. An initial literature review describes the evolution of theory related to three specific issues in the study of tourism – sustainability of tourism development as a desirable goal, stakeholder participation as a contributor to sustainability, and strategic planning as an appropriate framework within which stakeholder driven development activity can occur. The review concludes that these concepts are well supported in the literature, with little empirical evidence available on which to base any meaningful level of support. It is therefore argued that the value of these propositions may exist more strongly in theory than in practice. After discussing a number of factors which may negatively impact upon the practical implementation of these theoretical constructs, the paper proposes a quantitative instrument by which a specific tourism development planning process can be assessed for its conformity with desirable principles of sustainability in tourism development. Closing paragraphs indicate an intention to test this instrument across a variety of regional settings. 相似文献
