Numerous articles in the popular press together with an examination of websites associated with the medical, legal, engineering, financial, and other professions leave no doubt that the role of professions has been impacted by the Internet. While offering the promise of the democratization of expertise – expertise made available to the public at convenient times and locations and at an affordable cost – the Internet is also driving a reexamination of the concept of professional identity and related claims of expertise and standards of integrity.This paper begins with a presentation of case studies illustrating the ease by which impostors infiltrate the ranks of professionals. Reports of individuals masquerading as professionals via the Internet often reveal that these imposters cause harm to the unwary victims who rely on assertions of professional expertise. Such reports motivated the authors to examine the origins and evolution of the traditional roles of professions and professionals in today’s society, as well as question how, or whether, the standards for professional practice have been adapted to the challenges posed by technology, i.e., do statements of professional ethics provide a ‘guiding light’ for practitioners and their clients in the cyber age? The authors challenge the professions to consider the notion that technology forces a confrontation between the guild-like aspects of a profession that have served, on the one hand, to protect a profession from encroachment and, on the other hand, have purportedly protected the public.The authors conclude by presenting an examination of websites that show recognition of the challenges that the Internet poses to professionalism, as we have known it. Detailed discussion of the websites of two professions illustrates different approaches to responding to these challenges.  相似文献

Companies spend enormous amounts of energy and capital in creating value for customers, but less regard is given to actually capturing the value they have created. Segmentation based on buying behavior uncovers a tremendous differential in willingness to pay for subjective product attributes such as convenience, status, and quality. Purchase decisions are made through an assessment of a myriad of factors balancing perceptions of value components against price in a subtle, complex, and often sub-conscious decision matrix. Customer-centric pricing requires the simultaneous and continuous assessment of product attributes, customer perceptions, and the circumstances of time and place by listening to customers' actions. It is a means of assuring that companies assess the value they create for customers and extract that value from the marketplace.  相似文献

The determinants of productivity-enhancing micro-level restructuring are examined empirically with a panel of the twelve Finnish manufacturing industries. It is hypothesized that R&D leads to productivity diversity among plants, which in turn leads to the gradual reshuffling of input shares in the presence of dynamic competitive pressure. The effect of the creative destruction on industry productivity growth is measured with the between-component of productivity decomposition. Econometric results indicate with reasonable robustness that R&D generates creative destruction with a lag of several years. Some evidence is found that imports stimulate productivity-enhancing restructuring, especially when domestic R&D is low.JEL classification: O12, 014, 019, O31, O47*This paper is based on the chapter 8 of my PhD thesis which has been accepted by the Helsinki School of Economics (2003). The research has received financial support from Tekes (the National Technology Agency), and from the Yrjö Jahnsson Foundation. This paper has benefited from comments by Petri Böckerman, Pekka Ilmakunnas, Kabor Kezdi, and Petri Rouvinen, to whom I am grateful. I am also thankful to the referees for helpful comments. Lisa Roponen has checked my English. An earlier version of this paper has been presented at the EARIE 2002 conference in Madrid and at the Summer at CEU Workshop in Budapest in 2003. Data work and computations have been carried out at Statistics Finland, in accordance with the terms and conditions of confidentiality. I also wish to thank many individuals at Statistics Finland for their guidance regarding the properties of the data.

Nach der Euro-Umstellung Anfang 2002 entwickelte sich das Preisempfinden deutlich anders als der gemessene Verbraucherpreisindex. Inwieweit wird auch heute noch die Preisentwicklung von den Konsumenten übersch?tzt? Wie zuverl?ssig misst der von Hans Wolfgang Brachinger entwickelte „Index der wahrgenommenen Inflation“ dieses Ph?nomen? Zu welchen Ergebnissen kommen die von der EU-Kommission beauftragten Verbraucherumfragen? Die Verfasser geben ihre pers?nliche Auffassung wieder, die nicht unbedingt mit derjenigen der Deutschen Bundesbank übereinstimmen muss.  相似文献

If an investor borrows in a low interest currency and invests in a high interest currency, the interest differential accrues in a lumpy manner, formally just like the dividend payments on a stock. The investor will receive the interest differential discretely at the point when a position is rolled over from one day to the next. A position that is not held open overnight receives no interest differential because intradaily interest rates are zero. Using a large data set of intradaily exchange rate data, we run uncovered interest parity (UIP) regressions over different short time intervals taking careful account of the settlement rules in the spot foreign exchange market. We find results that are supportive of the uncovered interest parity hypothesis over very short windows of data that span the time of the discrete interest payment. However, adding even a few hours to the span of the window destroys the positive uncovered interest parity results.  相似文献

Our study aims to analyze the role of store format in retail competitive interactions, specifically, the relationship between growth, location strategy, and market response. To assess this relationship, we propose an extension of the classic models of spatial interaction, which incorporate the asymmetric competitive effects linked to the concept of store format. An empirical application allows us to confirm greater spatial rivalry within store formats (intra-format) than between store formats (inter-format). This implies a certain hierarchical organization when consumers select a retail store, first choosing the type of store at which they will shop and later a particular store within this format. The results are important for retailers who want to configure an optimal network of store locations as well as public administrators who must regulate commercial activity.  相似文献

This paper examines the critical role that organizational leaders play in establishing a values based climate. We discuss seven mechanisms by which leaders convey the importance of ethical values to members, and establish the expectations regarding ethical conduct that become engrained in the organizations climate. We also suggest that leaders at different organizational levels rely on different mechanisms to transmit values and expectations. These mechanisms then influence members practices and expectations, further increase the salience of ethical values and result in the shared perceptions that form the organizations climate. The paper is organized in three parts. Part onebegins with a brief discussion of climates regarding ethics and the critical role of values. Part two provides discussion on the mechanisms by which leaders and members transmit values and create climates related to ethics. Part three provides a discussion of these concepts with implications for theory, research, and practice.  相似文献

Many tasks and decisions in business, including management consulting, are performed in group settings. Computer-mediated communication (CMC) tools (e.g., Lotus Notes) are increasingly being used by businesses to support teams in a variety of settings. Considerable research in information systems has demonstrated the advantages of electronic brainstorming (EBS) for generic tasks involving only divergent thinking. However, it is unclear whether the benefits of CMC extend to tasks that require both divergent and convergent processes. Per task–technology fit theory (TTF) (Zigurs and Buckland 1998), the use of computer-based group communication support tools, including chat systems in wide-spread use today, may be less effective for convergent processes than for divergent processes. This study experimentally compares the performance of computer-mediated and face-to-face (FTF) teams on tasks requiring both divergent and convergent processes. Consistent with theoretical predictions, the results revealed that computer-mediated teams outperformed FTF teams in the divergent aspects of the tasks, while FTF teams outperformed computer-mediated teams in the convergent aspects of the tasks.  相似文献
