Third-party punishment has recently received attention as an explanation for human altruism. Feelings of anger in response to norm violations are assumed to motivate third-party sanctions, yet there is only sparse and indirect support for this idea. We investigated the impact of both anger and guilt feelings on third-party sanctions. In two studies both emotions were independently manipulated. ...

We consider the problem of approximately reconstructing a partially-observed, approximately low-rank matrix. This problem has received much attention lately, mostly using the trace-norm as a surrogate to the rank. Here we study low-rank matrix reconstruction using both the trace-norm, as well as the less-studied max-norm, and present reconstruction guarantees based on existing analysis on the R...

The paper attempts to develop a suitable accessibility index for networks where each link has a value such that a smaller number is preferred like distance, cost, or travel time. A measure called distance sum is characterized by three independent properties: anonymity, an appropriately chosen independence axiom, and dominance preservation, which requires that a node not far to any other is at l...

“Levels of analysis” has been a controversial topic in group research and has often been ignored by IS researchers leading to “cross-level fallacies” and “aggregation biases.” While the predominant practice in IS research is to assess group behavior by computing the “arithmetic mean of individual members’ behaviors,” recent studies have argued that groups should be treated separate from the ind...

The evaluation of an ability or skill happens in some kind of testbed, and so does with social intelligence. Of course, not all testbeds are suitable for this matter. But, how can we be sure of their appropriateness? In this paper we identify the components that should be considered in order to measure social intelligence, and provide some instrumental properties in order to assess the suitabil...

New technologies can contribute to one third of the increase in healthcare costs and it is important to obtain value and appropriateness with new devices, diagnostics, prostheses and procedures. HealthPACT has extended its role to assist with the implementation and evaluation of new devices in the absence of an organised clinical trial system for non-drug technologies. HealthPACT has establishe...

Literature reviews play an important role in the development of knowledge. Yet, we observe a lack of theoretical underpinning of and epistemological insights into how literature reviews can contribute to knowledge creation and have actually contributed in the IS discipline. To address these theoretical and empirical research gaps, we suggest a novel epistemological model of literature reviews. ...

In the following study, I develop two new institutional dimensions of consensus/majoritarian democracies, building on the variables of the two forms of democracy identified by Lijphart. Based on these two new dimensions, I establish a classification of consensual regime types and winnow out two permutations which would most closely approximate the ideal of domestic social conflict resolution, a...

It is well known that the tendency of unmarried pregnant women to marry has declined precipitously since the 1960s. This has been attributed to the undermining by new birth-control technologies of the "Shotgun-wedding" social norm that enforced commitment to marriage on pregnancy. However the fraction of marriages in which the bride was already pregnant before the wedding has remained remarkabl...

Purpose – To date, critical success factors (CSFs) for implementing knowledge management (KM) in small and medium enterprises (SMEs) have not been systematically investigated. Existing studies have derived their CSFs from large companies’ perspectives and have not considered the needs of smaller businesses. This paper is aimed to bridge this gap. Design/methodology/approach – Existing studies o...
