The study of norms (Ns) is recent but growing concern in the AI field (cf. [MOS92]; [SHO92]) as well within other formal approaches to social action, such as Game Theory (where theories of Ns began to appear long before, cf.[LEW69]; [ULL77]). The normative is an essential dimension of social life. An explicit model of such dimension is crucial for any theory of social action. Notions such as "s...

This article is a sequel to our earlier work [24]. The main objective of our research is to explore the potential of supervised machine learning in face-induced social computing and cognition, riding on the momentum of much heralded successes of face processing, analysis and recognition on the tasks of biometric-based identification. We present a case study of automated statistical inference on...

Many multichannel retailers are now offering customers the option to place their orders online and then pick them up from the retailers’ physical stores. As a relatively new type of multichannel retail service, the factors that influence consumers to use “online order/in-store pickup” (OOIP) remains largely unknown. This study uses the Behavioral Reasoning Theory to examine the factors that inf...

To extend previous cognition-based illegal downloading research, this project postulates that anticipated guilt, general emotions, attitudes, and norms collectively determine intentions to download digital files illegally. Our findings indicate that college students were more likely to download if they had more favorable attitudes, perceived greater social approval, and perceived more control o...

This research examines the effects of GSS and task type on informational and normative influence in small groups by analyzing group process. It extends Kaplan and Miller' s research on task type and informational and normative influence in small groups in an unsupported setting to a GSS setting. The two tasks used are an intellective task and a preference task, and the two support levels are un...

Abstract We present the result of a dual modeling of opinion network. The model complements the agentbased opinion models by attaching to the social agent (voters) network a political opinion (party) network having its own intrinsic mechanisms of evolution. These two sub-networks form a global network which can be either isolated from or dependent on the external influence. Basically, the evolu...

Information Technology represents a substantial investment for many corporations and constitutes a significant aspect of organizational work. However, its value is realized only when information systems are utilized by their intended users in a manner that contributes to the strategic and operational goals of the firm. Although there has been a plethora of studies done on the centrality of beli...

A journal-type blog offers audiences a venue, through which to exchange ideas about bloggers’ feelings and provide feedback, which could be regarded as a kind of social support. Based on a social support category system proposed by Cutrona and Suhr (1992), this study aims to identify the kinds of social support offered by audiences to continuous popular journal-type bloggers(A-list), as well as...

We model the endogenous emergence of social perceptions about occupations and their impact on occupational choice. In particular, an individual’s social approval increases with his community’s perception of his skill in his chosen career. These perceptions vary across communities because individuals better assess the skill of those in occupations similar to their own. Such imperfect assessment ...

To assess the relationship of postural changes in blood pressure to risk of myocardial infarction, 1359 men were followed for an average of 8.7 years. The men were participants in the Normative Aging Study, a longitudinal study of aging initiated in 1963 at the Veterans Administration Outpatient Clinic in Boston. It was found that the relationship of sitting blood pressure to the subsequent inc...
