An Internet presence is a critical early component in the process of building towards a fully operational and unified e‐commerce strategy. E‐commerce has significantly impacted logistics/supply chain strategies and the development and implementation of a website have become key issues for many firms within the transportation industry. This study provides an overview of website content within the motor carrier industry. Content analysis was used to assess the site design, informational content, and the interactive content of 152 motor carrier websites, and to compare the features offered on the Top 100 motor carrier firm websites with those offered on the sites of smaller carrier firms. 相似文献

The primary purpose of this research was to investigate the effect of investment in information technology in a supply chain. The results of that investigation are presented by focusing on an empirically tested supply chain relationship model containing both behavioral and operational constructs. The four behavioral constructs represented in the model are relationship trust, relationship commitment, relationship dependence, and long‐term relationship orientation. The four operational constructs represented in the model are retailer investment in interorganizational information technology, perceived supplier investment in interorganizational information technology, logistics efficiency, and logistics effectiveness. Among other findings, the results of the investigation found that perceived supplier investment in interorganizational information technology has a significant and positive effect on logistics efficiency. 相似文献

Close relationships between and among supply chain members are becoming more prevalent. However, there is lack of agreement in the literature and in practice concerning the characteristics of different interorganizational relationships. The resultant confusion is an obstacle to the progression of research and could cause problems among firms in a supply chain. Based on previous research and an exploratory study conducted with company executives responsible for supply chain management activities, this article seeks to introduce the concept of relationship magnitude (i.e., the extent or degree of closeness or strength of the relationship) and differentiate it from relationship type (i.e., classes of relationships that share common traits). Implications for managers and opportunities for future research are provided. 相似文献

Conditional probability distributions seem to have a bad reputation when it comes to rigorous treatment of conditioning. Technical arguments are published as manipulations of Radon–Nikodym derivatives, although we all secretly perform heuristic calculations using elementary definitions of conditional probabilities. In print, measurability and averaging properties substitute for intuitive ideas about random variables behaving like constants given particular conditioning information.
One way to engage in rigorous, guilt-free manipulation of conditional distributions is to treat them as disintegrating measures—families of probability measures concentrating on the level sets of a conditioning statistic. In this paper we present a little theory and a range of examples—from EM algorithms and the Neyman factorization, through Bayes theory and marginalization paradoxes—to suggest that disintegrations have both intuitive appeal and the rigor needed for many problems in mathematical statistics. 相似文献

In mid-January 2003 a severe speculative attack was launched against the exchange rate of the Hungarian forint. The attack
was very unusual in the history of foreign exchange speculations, since it was aimed at enforcing the appreciation — and not
the depreciation — of the currency targeted. The specific nature of this kind of speculation is closely related to Hungary’s
accession to the European Union in general and to EMU in particular. Since the other Central and Eastern European acceding
countries face similar problems and challenges, the Hungarian experience may involve some instructive lessons on monetary
and economic policy for them too. 相似文献

While the political benefits of the coming EU enlargement are relatively easy to identify, its economic and financial consequences
are less unequivocal. The following article examines the likely costs and benefits of enlargement to both existing and future
Members, and in particular how it will affect Germany, one of the few present EU Member States which has direct borders with
acceding states.
The article expresses the personal opinions of the author. 相似文献

The arrival of the 2001–2003 recession caused many to suppose that the so-called “New Economy” was now defunct. This article
addresses a number of related issues, including the question of the durability and viability of business cycles in the face
of the technological developments of the information age. It asks what went wrong with the New Economy and examines its characteristics
as well as its remaining possibilities and prospects for the future. Finally, it considers the spread of the Information Economy
to Europe, especially to Germany, the country that one might expect to be the leading European player, but which is not at
present actually a strong competitor for that role. 相似文献

This paper addresses Ravi Batra’s (2002 ) criticism of the basic comparative advantage gains‐from‐trade model. While Batra’s criticism is based on the selection view interpretation of real income, the gains from trade can only be properly understood from the options view interpretation of real income. I also show how a recent empirical implementation of the gains‐from‐trade model defies Batra’s claim that “the consumption gain . . . is not subject to measurement” (2002, p. 642). 相似文献
