The Information Systems Academic Discipline in Singapore

The global downturn in demand for IT skills has not left Singapore unscathed. While the demand for information systems graduates has not been as adversely affected as that for traditional computer science ones, there appears to be a drop in the entry quality of students seeking to do information systems degrees. While there appears to be some turnaround on the horizon, to better prepare for the future it is timely to examine the current state of IS as a discipline in Singapore and understand what might be the driving forces that shape it. Using Whitley\u27s theory of scientific change as a theoretical framework [1984a, 1984b], this case study seeks to explore the degree of professionalization and the maturity of IS as a discipline in Singapore through analysis of data gathered from in-depth interviews and secondary data sources. It is found that of the four constructs proposed by Whitley for determining if a discipline is a mature, distinct scientific one, the IS discipline in Singapore clearly satisfies three: the discipline has a high level of professionalization, strong scientific reputation, and well-established research competence and skills. While the IS researchers agree that the discipline has a common vocabulary with which to communicate with one another, they also agree that it is not unknown to the researchers outside the discipline and thus, in this aspect, the discipline only satisfies part of the fourth construct in Whitley\u27s theory

Empirical investigation of relational social capital in a virtual community for website programming

A virtual community of interest has a specific and narrow topic of discussion. Therefore, these communities attract registered members who are focused on knowledge sharing. The current research examines whether network ties, which are an aspect of structural social capital that can be categorized into strong and weak social ties, can provide a non-trivial explanation for members? trust, reciprocity, and identification in a virtual community for website programming interest. This relationship enables us to examine a context in which members share a common goal of resolving programming problems through knowledge sharing in contrast with other community settings where only general topics are discussed (e.g., societal and emotional issues). Data were collected through a survey of a virtual community for website programming composed of 69 members. Affirming conventional perception, results of the study indicate that weak ties affect the level of generalized trust and facilitate group identification. Remarkably, the number of members? strong ties is not significantly related to the degree of their perceived norms regarding generalized reciprocity. Reciprocity refers to a mutual expectation that a benefit granted at present should be repaid in the future. The results suggest two key points. First, even for a virtual community of interest, weak ties overshadow strong ties in explaining the outcome variables. Second, reciprocity is not guaranteed even in a focused form of discussion with a non-social topic that involves specialized knowledge. Therefore, virtual community members should be cautious even if ties are strong. Overall, results imply that virtual community administrators, particularly those who manage specialized communities, should be attentive to the strong and weak ties that exist among the community members

Investigating task coordination in globally dispersed teams:a structural contingency perspective

Task coordination poses significant challenges for globally dispersed teams (GDTs). Although various task coordination mechanisms have been proposed for such teams, there is a lack of systematic examination of the appropriate coordination mechanisms for different teams based on the nature of their task and the context under which they operate. Prior studies on collocated teams suggest matching their levels of task dependence to specific task coordination mechanisms for effective coordination. This research goes beyond the earlier work by also considering additional contextual factors of GDT (i.e., temporal dispersion and time constraints) in deriving their optimal IT-mediated task coordination mechanisms. Adopting the structural contingency theory, we propose optimal IT-mediated task coordination portfolios to fit the different levels of task dependence, temporal dispersion, and perceived time constraint of GDTs. The proposed fit is tested through a survey and profile analysis of 95 globally dispersed software development teams in a large financial organization. We find, as hypothesized, that the extent of fit between the actual IT-mediated task coordination portfolios used by the surveyed teams and their optimal portfolios proposed here is positively related to their task coordination effectiveness that in turn impacts the team's efficiency and effectiveness. The implications for theory and practice are discussed

Willingness to Continue with Software Projects: Effects of Feedback Direction and Optimism under High and Low Accountability Conditions

The willingness of managers to continue with software projects can be both beneficial and troubling. Management optimism can help bring promising projects to fruition, but can also cause valuable resources to be expended on faltering projects. This study examines three factors that can affect the willingness of managers to continue with software projects: feedback direction, feedback optimism, and accountability. Feedback direction is the objective information reflecting project prospects. Feedback optimism is the subjective mode with which the objective information has been framed. Accountability is the extent to which the manager feels responsible for project outcomes. Results of a study that manipulated these three factors showed that the effects of feedback direction and feedback optimism on willingness to continue with software projects were additive (either factor alone affected willingness to continue with software projects) when accountability was high but were interactive (both factors jointly affected willingness to continue with software projects) when accountability was low. These findings have useful implications for practice and further research

Competency-Based Approach to Information Systems Program Development: Guidance from the MSIS 2016 Global Competence Model

The panel has three objectives: First, it will present multiple perspectives on competency-driven approaches to developing and evaluating degree programs in Information Systems and compare the competency-driven approach to earlier, teaching topic or body of knowledge –driven approaches. Second, it will introduce the (nearly) completed version of the MSIS 2016 global competency model to the members of the global IS community and celebrate IS community’s efforts to improve the quality of graduate education. Third, the panel will discuss the essential role the competency-driven approach has as a foundation of MSIS 2016

Search for strong gravity in multijet final states produced in pp collisions at √s=13 TeV using the ATLAS detector at the LHC

A search is conducted for new physics in multijet final states using 3.6 inverse femtobarns of data from proton-proton collisions at √s = 13TeV taken at the CERN Large Hadron Collider with the ATLAS detector. Events are selected containing at least three jets with scalar sum of jet transverse momenta (HT) greater than 1TeV. No excess is seen at large HT and limits are presented on new physics: models which produce final states containing at least three jets and having cross sections larger than 1.6 fb with HT > 5.8 TeV are excluded. Limits are also given in terms of new physics models of strong gravity that hypothesize additional space-time dimensions

Measurement of the correlation between flow harmonics of different order in lead-lead collisions at √sNN = 2.76 TeV with the ATLAS detector

Correlations between the elliptic or triangular flow coefficients vm (m=2 or 3) and other flow harmonics vn (n=2 to 5) are measured using √sNN=2.76 TeV Pb+Pb collision data collected in 2010 by the ATLAS experiment at the LHC, corresponding to an integrated luminosity of 7 μb−1. The vm−vn correlations are measured in midrapidity as a function of centrality, and, for events within the same centrality interval, as a function of event ellipticity or triangularity defined in a forward rapidity region. For events within the same centrality interval, v3 is found to be anticorrelated with v2 and this anticorrelation is consistent with similar anticorrelations between the corresponding eccentricities, ε2 and ε3. However, it is observed that v4 increases strongly with v2, and v5 increases strongly with both v2 and v3. The trend and strength of the vm−vn correlations for n=4 and 5 are found to disagree with εm−εn correlations predicted by initial-geometry models. Instead, these correlations are found to be consistent with the combined effects of a linear contribution to vn and a nonlinear term that is a function of v22 or of v2v3, as predicted by hydrodynamic models. A simple two-component fit is used to separate these two contributions. The extracted linear and nonlinear contributions to v4 and v5 are found to be consistent with previously measured event-plane correlations

Measurement of the View the tt production cross-section using eμ events with b-tagged jets in pp collisions at √s = 13 TeV with the ATLAS detector

This paper describes a measurement of the inclusive top quark pair production cross-section (σtt¯) with a data sample of 3.2 fb−1 of proton–proton collisions at a centre-of-mass energy of √s = 13 TeV, collected in 2015 by the ATLAS detector at the LHC. This measurement uses events with an opposite-charge electron–muon pair in the final state. Jets containing b-quarks are tagged using an algorithm based on track impact parameters and reconstructed secondary vertices. The numbers of events with exactly one and exactly two b-tagged jets are counted and used to determine simultaneously σtt¯ and the efficiency to reconstruct and b-tag a jet from a top quark decay, thereby minimising the associated systematic uncertainties. The cross-section is measured to be: σtt¯ = 818 ± 8 (stat) ± 27 (syst) ± 19 (lumi) ± 12 (beam) pb, where the four uncertainties arise from data statistics, experimental and theoretical systematic effects, the integrated luminosity and the LHC beam energy, giving a total relative uncertainty of 4.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. A fiducial measurement corresponding to the experimental acceptance of the leptons is also presented

Search for vectorlike B quarks in events with one isolated lepton, missing transverse momentum, and jets at √s = 8 TeV with the ATLAS detector

A search has been performed for pair production of heavy vectorlike down-type (B) quarks. The analysis explores the lepton-plus-jets final state, characterized by events with one isolated charged lepton (electron or muon), significant missing transverse momentum, and multiple jets. One or more jets are required to be tagged as arising from b quarks, and at least one pair of jets must be tagged as arising from the hadronic decay of an electroweak boson. The analysis uses the full data sample of pp collisions recorded in 2012 by the ATLAS detector at the LHC, operating at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 20.3 fb −1 . No significant excess of events is observed above the expected background. Limits are set on vectorlike B production, as a function of the B branching ratios, assuming the allowable decay modes are B → Wt/Zb/Hb. In the chiral limit with a branching ratio of 100% for the decay B → Wt, the observed (expected) 95% C.L. lower limit on the vectorlike B mass is 810 GeV (760 GeV). In the case where the vectorlike B quark has branching ratio values corresponding to those of an SU(2) singlet state, the observed (expected) 95% C.L. lower limit on the vectorlike B mass is 640 GeV (505 GeV). The same analysis, when used to investigate pair production of a colored, charge 5/3 exotic fermion T 5/3 , with subsequent decay T 5/3 → Wt, sets an observed (expected) 95% C.L. lower limit on the T 5/3 mass of 840 GeV (780 GeV)
