Diffusion of social cognitive theory in information systems research: A bibliometric study
Recently, Social Cognitive theory (SCT) has been widely adapted across various disciplines in business and management as well as Information Systems (IS) research. In IS, the use of SCT remains in its early stages. Few bibliometric analyses have been published on mapping theories across previous literature. However, to date factors related to literature review mapping in relation to SCT in IS have not been much examined. This paper aims to investigate the expliotiation of SCT in IS research based on bibliometric analysis. In this study a biblimetric analysis is conducted on previous literature reviews/abstracts based on Association of Business Schools (ABS) journal rankings from Information Management field perspective. 62 articles in Information Management field have utilised SCT were published in 17 (out of 53 journals) between 1995 and 2010. The study findings has identified that the organisation/firm and actors as a unit of analysis, positivist paradigm, empirical and quantitative research as well as survey method were used significantly in combination with SCT in IS studies. This bibliometric study will provide the needed platform for a better understanding of high quality research activities. Consequently, this can be used as an indicator to measure research quality and the impact of future direction and exploitation of SCT in IS research
Collaborative video searching on a tabletop
Almost all system and application design for multimedia systems is based around a single user working in isolation to perform some task yet much of the work for which we use computers to help us, is based on working collaboratively with colleagues. Groupware systems do support user collaboration but typically this is supported through software and users still physically work independently. Tabletop systems, such as the DiamondTouch from MERL, are interface devices which support direct user collaboration on a tabletop. When a tabletop is used as the interface for a multimedia system, such as a video search system, then this kind of direct collaboration raises many questions for system design. In this paper we present a tabletop system for supporting a pair of users in a video search task and we evaluate the system not only in terms of search performance but also in terms of user–user interaction and how different user personalities within each pair of searchers impacts search performance and user interaction. Incorporating the user into the system evaluation as we have done here reveals several interesting results and has important ramifications for the design of a multimedia search system
Alter ego, state of the art on user profiling: an overview of the most relevant organisational and behavioural aspects regarding User Profiling.
This report gives an overview of the most relevant organisational and\ud
behavioural aspects regarding user profiling. It discusses not only the\ud

and barriers for user profiling and the most important conditions for\ud
the success of user profiling. Finally recommendations are made and\ud
suggestions for further research are given
Brain structural covariance networks in obsessive-compulsive disorder: a graph analysis from the ENIGMA Consortium.
Brain structural covariance networks reflect covariation in morphology of different brain areas and are thought to reflect common trajectories in brain development and maturation. Large-scale investigation of structural covariance networks in obsessive-compulsive disorder (OCD) may provide clues to the pathophysiology of this neurodevelopmental disorder. Using T1-weighted MRI scans acquired from 1616 individuals with OCD and 1463 healthy controls across 37 datasets participating in the ENIGMA-OCD Working Group, we calculated intra-individual brain structural covariance networks (using the bilaterally-averaged values of 33 cortical surface areas, 33 cortical thickness values, and six subcortical volumes), in which edge weights were proportional to the similarity between two brain morphological features in terms of deviation from healthy controls (i.e. z-score transformed). Global networks were characterized using measures of network segregation (clustering and modularity), network integration (global efficiency), and their balance (small-worldness), and their community membership was assessed. Hub profiling of regional networks was undertaken using measures of betweenness, closeness, and eigenvector centrality. Individually calculated network measures were integrated across the 37 datasets using a meta-analytical approach. These network measures were summated across the network density range of K = 0.10-0.25 per participant, and were integrated across the 37 datasets using a meta-analytical approach. Compared with healthy controls, at a global level, the structural covariance networks of OCD showed lower clustering (P < 0.0001), lower modularity (P < 0.0001), and lower small-worldness (P = 0.017). Detection of community membership emphasized lower network segregation in OCD compared to healthy controls. At the regional level, there were lower (rank-transformed) centrality values in OCD for volume of caudate nucleus and thalamus, and surface area of paracentral cortex, indicative of altered distribution of brain hubs. Centrality of cingulate and orbito-frontal as well as other brain areas was associated with OCD illness duration, suggesting greater involvement of these brain areas with illness chronicity. In summary, the findings of this study, the largest brain structural covariance study of OCD to date, point to a less segregated organization of structural covariance networks in OCD, and reorganization of brain hubs. The segregation findings suggest a possible signature of altered brain morphometry in OCD, while the hub findings point to OCD-related alterations in trajectories of brain development and maturation, particularly in cingulate and orbitofrontal regions
Workplace Violence and Security: Are there Lessons for Peacemaking?
Workplace violence has captured the attention of commentators, employers, and the public at large. Although statistically the incidents of workplace homicide and assault are decreasing, public awareness of the problem has heightened, largely through media reports of violent incidents. Employers are exhorted to address the problem of workplace violence and are offered a variety of programs and processes to prevent its occurrence. Many techniques, however, conflict with values that are critical to achieving sustainable peace. We focus on types of workplace violence that are triggered by organizational factors. From among the plethora of recommendations, we identify those responses that are most and least consistent with positive peace. We find that processes that promote privacy, transparency, and employee rights hold the most promise for peacemaking. We submit that such structures and processes can be transportable beyond the workplace to promote peace locally, nationally, and globally.http://deepblue.lib.umich.edu/bitstream/2027.42/39920/3/wp535.pd
The Use Of Personality Profiling As A Means To Assess Person-Organizational Fit To Inform Personnel Decisions
Profile matching refers to personnel selection based on candidate similarity to a pre-determined pattern. Although previous investigations support the use of personality data through univariate, linear-based selection methodologies, there is a paucity of research supporting the use of profile matching in a selection context, and very limited selection research has utilized a person-centered approach. Still, this support is necessary, given that a recent study estimated that the majority of consultative vendor organizations utilize some form of profile matching using personality patterns (Kulas, 2013). After generating profiles from the candidate pool, findings from the current study suggest that profiles have potential to offer predictive power beyond that of general mental ability for one organizational outcome, tenure. The results predicting job performance by profile were not supported. The current study further investigates the feasibility of profile generation based on an organization’s values and mission, to be used to assess fit for the purpose of selection. The use of person- and variable-centered approaches in understanding phenomenon is encouraged. Implications and future research are discussed
