声誉、隐私协议及信用图章对隐私信任和行为意图的影响研究

已有文献分别探讨了网站声誉、隐私协议和隐私信用图章对消费者信任的影响,但尚无研究综合考察此三个前因变量的作用,因此当各网站的声誉存在差异时,无法确定隐私协议和隐私信用图章在有效性上的优劣程度。为此,本文在Zucker的“信任建立”模型和“Pavlou”模型的基础上,提出了声誉,隐私协议和隐私信用图章影响隐私信任和信息披露意图的概念模型。实验室实验研究表明：三个前因变量对隐私信任和信息披露意图均具有正向影响;隐私信任对信息披露意图有正向影响;当处于竞争状态的网站的声誉均较低、均较高或者高、低不同时,隐私协议和隐私信用图章的作用存在差异,这说明网站应根据其声誉水平所处的相对位置采取措施。

基于隐私保护的经济统计信息发布

目前我国在经济统计信息的隐私保护方面还做得不够。主要表现为:信息发布时存在损失,丢掉了一些重要信息,不能很好地反映原有的涵义;信息共享时没有对统计数据进行隐私保护,存在隐私泄露。本文从用户对查询结果要求准确这一前提出发,提出一种基于交互的序列表发布模型,保证敏感信息不泄露,同时又能最大程度地减少经济统计信息的损失。实验结果表明,该模型对于大数据集的隐私具有较好的保护,丢失的重要信息少,能够满足经济统计信息发布的需要。

Digital Internationalization of Traditional Firms: Virtual Presence and Entrepreneurial Orientation

While digital technologies like the internet offer new and less cost-intensive ways to seize international opportunities, when it comes to traditional firms selling tangible products, little is known about their use of online channels for servicing foreign markets. This is especially the case for their choice between customized (active) or general (default) forms of corporate internationalization websites (viz. virtual presence modes). Building on the entrepreneurial orientation literature, we propose that firms that are more entrepreneurially orientated are more likely to capture internationalization opportunities with active internationalization websites. We further suggest that the threat of competitive pre-emption will moderate this relationship. Using a sample of Austrian SME exporters, we find support for the positive effect of entrepreneurial orientation on the use of active internationalization websites, but do not find a significant moderating effect of competitive pre-emption. In this way, we add to the growing research on digital internationalization by explaining the circumstances in which traditional firms choose between different internationalization website formats.     

Evaluation of hazard brochures using topic viewing durations: Application to tsunami evacuation brochures

This study describes a novel method of assessing risk communication effectiveness by reporting an evaluation of a tsunami information brochure by 90 residents of three Pacific coast communities that are vulnerable to a Cascadia Subduction Zone earthquake and tsunami—Commencement Bay, Washington; Lincoln City, Oregon; and Eureka, California. Study participants viewed information that was presented in DynaSearch, an internet-based computer system that allowed them to view text boxes and tsunami inundation zone maps. DynaSearch recorded the number of times each text box or map was clicked and the length of time that it was viewed. This information viewing phase was followed by questionnaire pages assessing important aspects of tsunami hazard and sources of tsunami warnings. Participants gave the longest click durations to what to do in the emergency period during earthquake shaking and in its immediate aftermath before a tsunami arrives—topics that should be displayed prominently in tsunami brochures and emphasized in talks to community groups. The smallest adjusted click durations were associated with advance preparations for a tsunami—topics that can be posted on websites whose URLs are printed in the brochures.     

The Authentic Leadership Inventory (ALI): Development and empirical tests

This paper presents the development and preliminary validation of a new measure of authentic leadership, the Authentic Leadership Inventory (ALI). It also assesses the recently developed Authentic Leadership Questionnaire (ALQ). Results indicate some concerns with the ALQ but support the content validity, reliability, factor structure, convergent and discriminant validity, concurrent validity, and freedom from impression management response bias of the ALI. Confirmatory factor analyses also do not support treating authentic or transformational leadership as universally global constructs. Instead, it is argued that future research would better be served by using separate authentic and transformational dimensions (rather than aggregate or global measures) to understand the unique aspects of both leadership constructs.     

Trade-offs in Online Purchase Decisions:: Two Empirical Studies in Europe

The Internet offers firms a new way to market their products and services and to interact with their end-consumers. While many firms have developed websites, very little is known about the trade-offs consumers are willing to make when making online purchases. With millions of websites competing for attention, online firms need to know in what way consumers make purchase decisions online. Consumers mainly evaluate websites on the basis of choice and convenience. In this paper, we present the results of two European studies that examine what consumers actually value in an online environment. In study 1, we assess choice-related trade-offs in terms of number of product categories, variety of products within a given category and product-related information. Conjoint analysis revealed that product-related information represents an important decision-making variable. In study 2, we assess convenience-related trade-offs in terms of logistics, fulfilment and security. Conjoint analysis revealed that fulfilment is the most important variable related to online handling. Finally, our study clearly indicates that firms have to distinguish different consumer segments on the basis of their preferences. This knowledge enables online firms to use their resources more effectively.     

评分不一致性对在线评论有用性的影响——归因理论的视角

哪些因素会影响在线评论的有用性一直是理论界和实践界都十分关心的问题,但现有研究对在线评论的星级评分是如何影响评论有用性这一问题仍未形成统一的结论。基于此,本文以归因理论为分析框架,构建了在线评论的星级评分与产品的平均星级间的不一致性对评论有用性的影响的研究模型,并重点探讨产品的评论总量以及评论的星级评分和平均星级间差异的方向对这一影响的调节作用。本文以携程网上832233条酒店评论为样本,采用零膨胀负二项回归方法对理论模型进行了实证检验,研究结果表明,评分不一致性对评论的有用性有显著的负向影响,而某种产品的评论总量以及星级评分和平均星级间差异的方向对评分不一致性和评论有用性间的关系起到调节作用。当产品的评论总量越高或评论的星级评分与产品的平均星级间的差异为正向差异时,评分不一致性对评论有用性的负向影响越强。本文的研究成果既为理解在线评论有用性提供了理论贡献,也有助于电子商务或第三方评论网站管理和应用在线评论。     

HOW DO INFORMAL AGREEMENTS AND REVISION SHAPE CONTRACTUAL REFERENCE POINTS?

The notion of contracts as reference points provides the basis for a deeper understanding of important phenomena such as the employment contract, vertical integration, firm scope, authority, and delegation. Previous experiments lend support to this notion but they ignore realistic aspects of trading relationships such as informal agreements and ex‐post renegotiation or revision. Here we show that the central behavioral mechanism underlying contractual reference points is robust to such considerations. Our data reveal that informal agreements can mitigate the trade‐off between rigidity and flexibility but they do not fully resolve the problem of misaligned reference points. Our experiments also show that contract revision is a more nuanced process than the previous literature has recognized. We find, for example, that it is sometimes better for parties to write a simple (rigid) contract and then revise it ex post if needed, rather than to anticipate and include future contingencies in a (flexible) contract from the outset.

Redundancy in Designs

The author contends that a previous Risk Analysis article overemphasized the pitfalls of incorporating redundancy into designs. Relevant aspects of that article are reviewed and commented upon, then the potentials and pitfalls of redundancy in systems and procedures are more broadly discussed. To provide a solid foundation for that discussion, some definitions for systems risk analysis terminology are presented. It is shown that pairs and larger sets of related failures (the physical causes of shortfalls in redundancy effectiveness) can be divided into two types: (1) cascading/induced failures and (2) common-external-cause failures. Each type has its own physical characteristics and implications for mathematical modeling. Service experience with large-commercial-airplane jet-engine propulsion systems is used to illustrate the two types of related failures. Finally, an overview is provided of event-sequence analysis, an alternative approach to systems risk analysis. When the possibility of related failures of mutually-redundant system elements must be accounted for, event-sequence analysis can usually do that better than fault-tree analysis.     

Optimal Control of Selling Channels for an Online Retailer with Cost‐per‐Click Payments and Seasonal Products

The problem studied in this paper is a predigestion of the decision faced by online retailers (etailers) that advertise on publisher or comparison‐shopping websites. An etailer may sell its product not only through its online and bricks‐and‐mortar stores, but also through the websites of one or more third parties (e.g., Yahoo.com). However, the etailer has to pay a certain amount to such third parties in an action‐based payment scheme, such as a cost‐per‐click (CPC) scheme. Under the CPC scheme, payment is based solely on click‐throughs, which means that the etailer pays only when a shopper clicks through to the product page of its website. Only a fraction of such clicks lead to actual sales. The extra cost that is associated with shoppers who first click through to the third‐party websites makes them less attractive as customers than those who directly visit the etailer's online store. Moreover, the CPC rate for a prominent placement is normally set by competitive bidding, and thus varies over time. Therefore, the etailer needs to decide dynamically whether or not to list on a third‐party website. The structural properties of the optimal policy are discussed, and numerical examples are given to show the revenue impact of dynamic listing control.
