The extent of influence: An alternative approach to identifying dominant contributors to a discipline’s literature

Most studies of scholarly influence within disciplines using citation data do not investigate the extent of an individual’s influence; does it extend over a number of years with a sequence of publications or is it confined to a short period and a small number of publications? Using bibliographic data from a series of quadrennial reports into developments in UK geography, this paper finds that few authors are cited on more than one occasion.     

Development of severe accident management guidance (SAMG) for the Canadian CANDU 6 nuclear power plants

This paper discusses the severe accident management guidance (SAMG) development process undertaken for the Canadian CANDU 6 nuclear power plants (NPPs); the customization process of the generic CANDU SAMG for the Point Lepreau NPP is presented. Examples of severe accident management (SAM) guidelines related to containment pressure control are included in this paper. This paper also provides an overview summary of the severe accident analysis program at Atomic Energy of Canada Limited (AECL) that complements the SAM guidelines development process for the CANDU 6 NPPs in Canada. These analyses provided insights into the accident progression and basis to develop the SAM guidelines.

Relation of operator Schmidt decomposition and CNOT complexity

We consider two-qubit operators and provide a correspondence between their Schmidt number and controlled-NOT (CNOT) complexity, where the CNOT complexity is up to local unitary operations. The results are obtained by complementary means, and a number of examples are given.     

Longitudinal associations of marital quality and marital dissolution with the incidence of DSM-III-R disorders.

This study examined whether getting divorced was related to the subsequent incidence of DSM-III-R disorders across a 2-year period, controlling for the perceived quality of the marriage prior to the divorce. Data were used from 4,796 adults aged 18 to 64, who had participated in 3 waves (i.e., 1996, 1997, and 1999) of a large-scale epidemiological study conducted in The Netherlands. Results showed that getting divorced was prospectively linked to both the total and new case incidence of alcohol abuse and dysthymia, as well as to the new case incidence of social phobia. Adults who had divorced, however, were not more likely to develop a mental disorder if they had reported low levels of marital quality prior to the divorce. Thus, the marital discord underlying a divorce rather than divorce itself appeared to determine the onset of clinically relevant mental health problems.

From pattern to practice: Evaluation of a design pattern fostering trust in virtual teams

This article describes the implementation and evaluation of a design pattern that fosters trust in mediated collaborative settings. The pattern proposed here should provide a profile with static and/or dynamic information about the participants of a collaborative environment. It aims to foster initial (in the first two to three weeks) trust in situations in which people do not know each other and do not have a chance to meet, but need to collaborate. A simple and low cost implementation of this pattern was realized by conducting a case study with participants of the European Virtual Seminar on Sustainable Development (EVS). They were asked to fill in a template with personal information about themselves. In the EVS, students collaboratively have to address sustainable development problems. Afterwards, students were questioned on the use of this template, called PEXPI, and their impressions of each other during and after the EVS; questionnaires and a semi-structured interview were used. The results show that the implementation of the static profile, derived from the pattern, initially helped students to form an impression of each other. After this initial period, however, students base their impression on factors such as the quality of work-related contributions, behaviour during collaboration (e.g. responsiveness), and communication style. This case study also shows that the pattern could easily be applied and transferred to a new context, as long as the conditions described in the ‘context’-section of the pattern, were met. The case study provided a means for evaluation of the pattern and a source for its refinement.     

What Do We Really Know About First‐Person‐Shooter Games? An Event‐Related,High‐Resolution Content Analysis

Multiple studies have been addressing effects of playing violent video games. However, most such studies neglect users' individual experiences. In fact, each player's gameplaying choices creates his or her own specific game content. Within this study we analyzed the individually generated content of a typical first-person-shooter game with high temporal resolution and associated them with physiological response measures (heart rate, skin conductance) collected during the game play. Thirteen experienced game players played the multiplayer first-person-shooter game " Tactical Ops: Assault on Terror " for 50 minutes on average. Playing phases and events in between were analyzed on both an intraplayer and interplayer level. Results indicate varying gaming experiences in the users and distinct arousal levels over time and for different game events.     

New lower matrix bounds for the solution of the continuous algebraic lyapunov equation

New lower matrix bounds are derived for the solution of the continuous algebraic Lyapunov equation (CALE). Following each bound derivation, an iterative algorithm is proposed to derive tighter matrix bounds. In comparison to existing results, the presented results are more concise and are always valid when the CALE has a non‐negative definite solution. We finally give numerical examples to show the effectiveness of the derived bounds and make comparisons with existing results.
