摘要：While researchers go to great lengths to justify and prove theoretical links between constructs, the relationship between measurement items and constructs is often ignored By default, the relationship between construct and item is assumed to be reflective, meaning that the measurement items are a reflection of the construct. Many times, though, the nature of the construct is not reflective, but rather formative. Formative constructs occur when the items describe and define the construct rather...

摘要：As organizations operate across greater distances, scholars are increasingly interested in the work of geographically dispersed teams and the technologies that they use to communicate and coordinate their work. However, research has generally not specified the dimensions (spatial, temporal, or configurational) and degrees of team dispersion, nor has it articulated the theoretical connections between those dimensions and important team outcomes. This research essay expands upon previous field a...

摘要：This article is based on the introduction of a telemedicine system in the jungles of northeastern Peru. The system was designed by a European consortium led by a Spanish polytechnic in cooperation with two universities in Lima and the Peruvian Ministry of Health. The purpose of the system was to improve health conditions by extending science-based medicine into a region with well-established traditional healing practices. The central analytical focus of this article is on the interplay between...

摘要：This paper reports the results of an exploratory field experiment in Singapore that assessed the values of two types of privacy assurance: privacy statements and privacy seals. We collaborated with a local firm to host the experiment on its website with its real domain name, and the subjects were not informed of the experiment. Hence, the study provided afield observation of the subjects' behavioral responses toward privacy assurances. We found that (1) the existence of a privacy statement ind...

摘要：The objective of this paper is to contribute to a deeper understanding of system usage in organizations by examining its multilevel nature. Past research on system usage has suffered a levels bias, with researchers studying system usage at single levels of analysis only (e.g., the individual, group, or organizational level). Although single-level research can be useful, we suggest that studying organizations one level at a time will ultimately lead to an unnatural, incomplete, and very disjoin...

摘要：Two constructs used to measure product understanding performance are actual product knowledge and perceived website diagnosticity (i.e., the extent to which consumers believe a website is helpful for them to understand products). The experimental results show that (1) both videos and VPE lead to higher perceived website diagnosticity than static pictures; (2) under a moderate task complexity condition, VPE and videos lead to the same level of actual product knowledge, but all are more effectiv...

摘要：Internet auctions demonstrate that advances in information technologies can create more efficient venues of exchange between large numbers of traders. However, the growth of Internet auctions has been accompanied by a corresponding growth in Internet auction fraud. Much extant research on Internet auction fraud in the information systems literature is conducted at the individual level of analysis, thereby limiting its focus to the choices of individual traders or trading dyads. The criminology...
