The Barratt Impulsiveness Scale is one of the most commonly used scales to measure impulsivity. It has demonstrated validity in several neuropsychiatric populations and correlates with objective neuropsychological measures and impulsivity-related behaviors in healthy individuals. Neuroimaging studies show that BIS scores relate to prefrontal structure and function, as well as central serotonerg...

Software piracy has been a serious problem for decades and continues to cost software industry some billions of dollars each year. In this study we examine the Normative and Informational Social Influences that affect an individual’s decision to buy or use pirated software. Based upon previous research about ethical decision making in software adoption, and consumer susceptibility to social inf...

Current models of causal induction are seriously compromised because they cannot represent variations in cause-effect timing. Theoretical considerations and empirical evidence converge, suggesting that cause-effect timing influences induction beyond mere interference, in line with predictions of psychophysical models of rate comparison. Rather than accepting two distinct cognitive processes for...

This paper examines the external influences on ERP project abandonment. The recent literature supposes that the adoption of ICT can be motivated by external institutional pressures, in a process called isomorphism. To gain legitimacy, some firms accept mimetic, coercive, and normative pressures arising from its organizational field to adopt some structures and technologies. Same process is expe...

Encouraged by recent practical observations of employees’ usage of public cloud services for work tasks instead of mandatory internal support systems, this study investigates end users’ utilitarian and normative motivators based on the theory of reasoned action. Partial least squares analyses of survey data comprising 71 computer end users at work, employed across various companies and industri...

It is the absence of preventable harm to a patient during the process of health care, ensuring safer care is an enormous challenge, psychosocial variables influences behaviors of human. The theory of planned behavior (TPB) is a well-validated behavioral decision-making model that has been used to predict social and healt...

We present a theoretical model of a linear public good game in which heterogeneous players express social approval after observing contributions. The model explains how social approval is expressed and predicts positive contributions if subjects have a preference for social approval. Using a controlled laboratory experiment we test our model. In the experiment, subjects conduct computerized tas...

In this paper, we present the annotation purposes for a personal as well as for a collective use. In the context of digital documents, annotation systems allow not only to annotate passages but also to comment or reply to annotations within discussion threads (similar feature than forum’s one). Thus, readers can express their points of view, debate and even reach a consensus about annotated pas...

This paper empirically investigates the impact of normative social influence on group homogeneity in media preferences and group meeting outcomes in a setting where 58 student groups voluntarily used various communication media over a three-month software development project period. Group homogeneity in media preferences was argued to mediate the impact of normative social influence on group me...
