我国青少年旅游网络建构的初步探讨

青少年目标市场不仅是目前旅游市场的重要组成部分,随着年龄的增长,他们将成为未来旅游市场的中坚.本文提出了建构青少年旅游网络的设想.笔者先分析了建构青少年旅游网络的可能性与必要性,在此基础上指出了现阶段青少年旅游市场存在的一系列问题,伴随着对这些问题的思考,笔者建构了青少年旅游网络的基本框架,并界定了青年旅游网络的内涵,对具体的建构工作提出了思路.     

中国省会城市职能结构特征的比较研究

从城市职能结构类型、发展阶段和效益三方面比较分析了我国省会城市职能结构的特征,结论如下:①在省会城市中,制造业和建筑业职能仍然占据重要地位,科教文卫、行政、金融保险业、房地产业等职能地位亟待提升.②84.62%的省会城市第三产业比重相对于第二产业比重比率稳步上升.③省会城市职能结构效益整体状况得到提高,高效益城市所占比例增加,低效益城市所占比例减少.从变化趋势类型来看,效益上升型城市所占比例居于第二位,效益下降型城市所占比例最低,这也验汪了省会城市职能结构效益趋于提升的态势.

INTENSITY-BASED VALUATION OF RESIDENTIAL MORTGAGES: AN ANALYTICALLY TRACTABLE MODEL

This paper presents an analytically tractable valuation model for residential mortgages. The random mortgage prepayment time is assumed to have an intensity process of the form h _t = h ₀( t ) +γ ( k − r _t )⁺ , where h ₀( t ) is a deterministic function of time, r _t is the short rate, and γ and k are scalar parameters. The first term models exogenous prepayment independent of interest rates (e.g., a multiple of the PSA prepayment function). The second term models refinancing due to declining interest rates and is proportional to the positive part of the distance between a constant threshold level and the current short rate. When the short rate follows a CIR diffusion, we are able to solve the model analytically and find explicit expressions for the present value of the mortgage contract, its principal-only and interest-only parts, as well as their deltas. Mortgage rates at origination are found by solving a non-linear equation. Our solution method is based on explicitly constructing an eigenfunction expansion of the pricing semigroup, a Feynman-Kac semigroup of the CIR diffusion killed at an additive functional that is a linear combination of the integral of the CIR process and an area below a constant threshold and above the process sample path (the so-called area functional). A sensitivity analysis of the term structure of mortgage rates and calibration of the model to market data are presented.

Functions and failures: how to manage technological promises for societal challenges

Technological promises are becoming part of the way in which scientific and technological communities try to attract the attention of stakeholders, aiming at legitimation, reputation, and funding. Not all promises, however, become reality. With the increase in the use of promises comes the risk of disillusion and cynicism, which may affect negatively policy-makers and the public opinion. The paper suggests that the introduction in the field of S&T and innovation policy of a tool commonly used in engineering fields aimed at identifying and measuring all possible failures of a proposed technology. Instead of focusing on the magnitude of promises, it suggests that a useful perspective can be gained by placing systematic attention to the negative side, i.e. all reasons why a given technology may fail to deliver the promises. The paper develops the methodology, presents a case study, and illustrates the benefits of using it in policy-making.

Cross‐Functional Integration: Concept Clarification and Scale Development

The centrality of cross‐functional integration (CFI) to supply chain theory and practice has long been recognized. Yet researchers continue to struggle with consistently defining or measuring the CFI construct, thus limiting the utility of CFI research. This research develops (1) a comprehensive definition of CFI that synthesizes previous supply chain research and (2) a valid set of scale items that measure the conceptual domain outlined by this definition. The goal is to build a common foundation for extending knowledge on CFI's antecedents and consequences, and ultimately to improve scholars’ ability to guide a broader practitioner community still struggling to achieve integration in their organizations.     

Information Search,Alternatives Evaluation,and Coping Mechanisms of Functionally Illiterate Consumers in Retail Settings: A Developing Economy Context

Little research has been carried out with regard to marketing to functionally illiterate consumers, despite the size and purchasing power of this market segment. This qualitative study examined the decision-making processes and coping mechanisms of functionally illiterate consumers in the South African grocery shopping environment. The findings provide insights that have important theoretical and practical implications for marketers, retailers, and policy makers. For functionally illiterate consumers, the information-search stage of the consumer decision-making process is either nonexistent or limited to a few trusted sources, such as friends and family, which often occurs only after a purchase has been made. Furthermore, these consumers face difficulties in a grocery store environment but have developed several coping mechanisms to compensate for their limited literacy skills.     

Multichannel marketing: the operational construct and firms’ motivation to adopt

Multichannel marketing has been gaining attention to its importance in both practice and research in the recent years with the rapid diffusion of Information Communication Technology. Due to the relative recency and rapid proliferation of research in the subject, the literature lacks a well-defined construct of multichannel marketing generalizable to different types of firms, and lacks understanding of the actual reasons that firms adopt multichannel marketing. Through comparing and complementing the extant literature with practitioners’ perspectives from interviews with 32 Italian firms, the authors propose a comprehensive and generalizable framework of the multichannel marketing construct, and identify and categorize the firms’ motivations to adopt the multichannel marketing practice. Furthermore, some unforeseen but interesting factors emerged from the interviews. Future research opportunities and managerial implications of the study are discussed.
