Measurement of the ZZ production cross section and limits on anomalous neutral triple gauge couplings in proton-proton collisions at sqrt{s} =7 TeV with the ATLAS detector

A measurement of the ZZ production cross section in proton-proton collisions at sqrt{s} = 7 TeV using data collected by the ATLAS experiment at the LHC is presented. In a data sample corresponding to an integrated luminosity of 1.02fb-1, 12 events containing two Z boson candidates decaying to electrons and/or muons were observed. The expected background contribution is 0.3^{+0.9}_{-0.3} (stat) ^{+0.4}_{-0.3} (syst) events. The total cross section for on-shell ZZ production has been determined to be \sigma_{ZZ}_{tot}= 8.4^{+2.7}_{-2.3}(stat) ^{+0.4}_{-0.7}(syst)\pm 0.3 (lumi) pb$ and is compatible with the Standard Model expectation of 6.5^{+0.3}_{-0.2} pb calculated at the next-to-leading order in QCD. Limits on anomalous neutral triple gauge boson couplings are derived.Comment: 8 pages, Proceedings of the DPF-2011 Conference, Providence, RI, August 8-13, 201

Understanding The Role Of Social Capital In Expertise Coordination In Information Systems Development (isd) Teams

Information system development (ISD) project is a knowledge-intensive teamwork process which requires members to coordinate their expertise to generate the final outcome. Breakdown or coordination and insufficient knowledge integration have been reported as critical factors which lead to ISD project failure. Most existing coordination literature focus on the effect of administrative coordination mechanisms toward project performance which hints that more efforts are needed to understand expertise coordination and explore ways to improve it. Addressing the above issues, two studies in this dissertation attempt to understand expertise coordination within the IS development team based on social capital perspective. The first study, based on intention-behavior literature, knowledge management research, and Gerwin\u27s (2004) coordination model, investigates relationships among willingness, competence, and actual expertise coordination. The relationships between expertise coordination and teamwork outcomes are also examined. The second study incorporates social capital theory and examines (1) dependencies among three dimensions of social capital and (2) linkage between social capital and expertise coordination. Data collected from more than five hundred information systems project team members was used to test the proposed hypotheses. The analysis results confirmed most of the hypotheses. This dissertation contributes to coordination, project management, and team mental model research through many perspectives. In each study, directions for management practice and future research are discussed

When does One Weight Threats more? An Integration of Regulatory Focus Theory and Protection Motivation Theory

Protection motivation theory has been adopted to understand the driver of information security behaviors broadly. Based on theoretical arguments and empirical results, security behaviors are driven by individuals’ appraisal toward threats and coping. However, while most study focus on the impacts of independent variables on dependent variables, previous studies largely ignore a fact that, under certain conditions, individuals tend to weight the importance of threat (or coping) appraisal more. Given that the goal of security behavior is to protection information and individuals may be oriented to the goal differently, we argue that the magnitude of the impacts of threat and coping appraisal may be contingent on individuals’ goal orientation. Specifically, this study attempts to integrate protection motivation theory with regulatory focus theory and explore whether (1) threat appraisal is more critical when prevention focus in high and (2) coping appraisal generates more impact when promotion focus is high. By integrating protection motivation theory with regulatory focus theory and revealing the moderating roles of regulatory focus on protection motivations, we expect to contribute to protection motivation theory by showing the effects of threat and coping appraisal may be contingent on certain conditions

The Influence of Information Security Stress on Security Policy Compliance: A Protection Motivation Theory Perspective

The occurrence of security incidents will not only cause substantial loss to the enterprise but also serious damage to goodwill. An enterprise has to formulate and implement effective security policies to reduce the occurrence of security incidents. However, the process of promoting the security policy will put stress on employees. The focus of this paper is whether these pressures will affect staff\u27s compliance with the security policies based on the protection motivation theory. This study uses a survey method and 324 responses are collected. The results show that security task stress and security job stress have a significant impact on the formation of security role stress. Security role stress impacts threat and coping appraisals leading to security compliance

Managers\u27 Perceived Benefits of Using Electronic Procurement in Taiwan

Facing the competitive pressure from new hospitals and new regulations from the Bureau of National Health Insurance, hospital managers in Taiwan are concentrating on reducing the hospital operation costs and improving the healthcare quality. Practitioners and academic researchers agree that reducing the pharmacy cost is one of the best solutions to sustain competitive advantage. As electronic commerce becomes popular in many industry sectors, e- procurement is growing rapidly in the healthcare industry. The purpose of this paper is to investigate the managers\u27 perceptions of benefits of using electronic procurement system. After surveying 152 hospitals in Taiwan, we find that hospital size and adoption status have significant influence on many perceived benefits. Managers in large hospitals show stronger confidence in the perceived benefits of using e-procurement than their counterparts of small hospitals

A study of the Effects of Information Security Advocacy

This study adopted protection motivation theory, construal-level theory, and regulatory focus theory to build a model to understand the effects of information security advocacy. The purposes are as follows: first, understand the impacts on the threat/coping appraisals that different construal-level of security warning messages have. Second, understand the impacts on the information security compliance intention that threat/coping appraisals have. Lastly, understand the moderating effects of different regulatory foci on the relationship between different construallevel of warning messages and the threat/coping appraisals or between the threat/coping appraisals and the compliance intention. In this study, the experimental method and survey are employed. Eight different scenarios related to mobile phone authority setting are designed to proceed with the experiments. At the beginning of this experiment, the participants will be manipulated to a particular regulatory focus (prevention or promotion), then be assigned to one of eight scenarios randomly

An Evaluation of Publication Productivity in Information Systems: 1999 to 2003

University hiring, promotion and tenure decisions make researchers\u27 publication productivity an important issue. This study reports on data about publication productivity of information systems (IS) researchers from 1999 to 2003. We collected information about IS papers published in twelve IS journals during this period. After classification, the most productive individuals and institutions for this sample are identified. We also compared our findings with past research to demonstrate the changes in publication productivity over time. Publication productivity changes somewhat among researchers and institutions
