摘要：This paper draws from communication research and negative asymmetry theory to examine how employee social network ties at work affect deep structure use and job performance in the context of an enterprise system (ES) implementation. Specifically, we examine how the content (i.e., advice and impeding) and source (i.e., friends and acquaintances) of social network ties interact with one another to influence both deep structure use of the new ES and employee job performance. A longitudinal field ...

摘要：Standards are central to many information technology (IT) applications, and the development processes for these standards play a key role in the evolution of information systems (IS). We model the development of IT standards by technology suppliers as a coevolutionary technological search process under supply-side network effects, and we examine how the characteristics of the standards development process influence its outcomes. In line with common intuition and prior research, we find that pe...

摘要：This research questions how social media use affords new forms of organizing and collective engagement. The concept of connective action has been introduced to characterize such new forms of collective engagement in which actors coproduce and circulate content based upon an issue of mutual interest. Yet, how the use of social media actually affords connective action still needed to be investigated. Mixed methods analyses of microblogging use during the Gulf of Mexico oil spill bring insights o...

摘要：Based on the wisdom of the crowd effect, consumer-generated online reviews are supposed to help consumers make more accurate product evaluations. However, the large amount of information in the reviews, coupled with conflicting opinions, can make it difficult for consumers to identify and consider those attributes relevant to their decision. Thus, while online product reviews are generally believed to empower consumers, we suggest that they may have swaying effects in that attribute preference...

摘要：Prior information systems research highlights the vital role of information technology (IT) for innovation in firms. At the same time, innovation literature has shown that accessing and integrating knowledge from sources that reside outside the firm, such as customers, competitors, universities, or consultants, is critical to firms' innovative success. In this paper, we draw on the knowledge-based view of the firm to investigate how search in external knowledge sources and information technolo...

摘要：There has been widespread use of auto-ID technologies. With the increasing diffusion of smartphones, the potential to serve content to shoppers using auto-ID technologies is starting to receive interest. Using a design science approach, we design and build, theorize about, and compare six shopping assistance artifacts by manipulating the hardware design-barcode scanner versus radio frequency identification (RFID) reader-and content design-product information versus product review versus both. ...

摘要：With the increasing popularity of product recommendation networks in e-commerce, researchers and practitioners are eager to understand how they can strategically manage product assortments through the manipulation of such networks to drive demand. We examine product recommendation networks in e-commerce to investigate how the demand of a product is influenced by product network attributes in terms of network diversity and network stability. We also examine whether the demand of a product is in...

摘要：Collecting and displaying product reviews written by consumers is a common practice for many retail websites. These websites, however, differ in their choice to reveal aggregate review statistics on the product list displayed while consumers browse or search to make initial product selections. This study proposes an analytical model to examine the conditions in which revealing average star ratings on the product list is more profitable than not revealing this information. Noting that consumers...

摘要：In this study, we argue that institutional factors determine the extent to which hospitals are symbolic or substantive adopters of information technology (IT) specific organizational practices. We then propose that symbolic and substantive adoption will moderate the effect that IT security investments have on reducing the incidence of data security breaches over time. Using data from three different sources, we create a matched panel of over 5,000 U. S. hospitals and 938 breaches over the 2005...

摘要：In this paper, we estimate the impact of enforcing the Convention on Cybercrime (COC) on deterring distributed denial of service (DDOS) attacks. Our data set comprises a sample of real, random spoof-source DDOS attacks recorded in 106 countries in 177 days in the period 2004-2008. We find that enforcing the COC decreases DDOS attacks by at least 11.8 percent, but a similar deterrence effect does not exist if the enforcing countries make a reservation on international cooperation. We also find ...
