Feature Repurposing and Cognitive Efficiency in Financial Trading Systems

Many IS research domains such as cognitive fit and information overload assume that the user selects from a fixed menu of IS features to accomplish goals. IS pliability researchers offer a new perspective by recognizing the users’ discretion in altering or creating new features. While this IS pliability research has important implications, it is currently descriptive rather than explanatory. To explore IS pliability in the form of causal propositions, we examine data from a Fortune 1000 brokerage firm where some traders created what the IS developers considered superfluous “extra” accounts. Levering insights from the referent theory of cognitive niche construction, we propose that these multiple accounts align the representation of information presented with the users’ conceptual trading strategies. This alignment in turn facilitates trading research through the reduction of task switching and the learning benefits supported by category labels. The empirical analysis is consistent with these propositions

Going IT Alone: The Experienced IT Worker as Integrator of Business and IT Domains of Knowledge

Though the need for user participation to successfully develop information systems is a commonly accepted MIS axiom, empirical studies have failed to consistently establish the benefits of user participation. To resolve this paradox, we reconsider the underlying premise that business knowledge must be provided by business workers. Instead, as IT is embedded in the business, IT workers necessarily learn both domains in the act of work, and the integration of the two can be achieved through experienced IT workers. To examine this proposition, we studied a group of IT workers who implemented an IS in forty-seven sites over a two year period. Through learning curve methods and change-point analysis, we find that the IT workers achieved greater success as their experience increased while concurrently user participation activities decreased. These findings, consistent with the main proposition, suggest a new approach to valuing the IT workers’ contributions

Social cognition, impulsivity, and emotion regulation factors in aggressive behavior among children with attention-deficit/hyperactivity disorder.

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) exhibit greater levels of aggressive behavior than their typically developing peers, often resulting in impairment in social and family functioning. Aggressive behavior is often differentiated into two functions: reactive, or “hot-blooded” and proactive, or “cold-blooded” aggression. Prior research has identified several factors contributing to aggressive behavior within a general population, including emotion dysregulation, negative urgency, social information processing (SIP), and parenting behaviors. A paucity of research has examined these factors within an ADHD population. Thus, the present study aimed to examine social, emotional, behavioral, and cognitive factors associated with aggression among children with ADHD. Specifically, the present study investigated the independent and combined roles of emotion dysregulation and negative urgency in reactive aggression as well as the independent and interactive roles of SIP and parenting behaviors in proactive aggression. Participants included 28 children with ADHD and their parents. Participants, their parents, and their teachers completed questionnaires to assess emotion dysregulation, negative urgency, aggressive behavior, and parenting behaviors. Parents completed a diagnostic interview to confirm ADHD diagnostic status. Children completed one task to assess aggression and responded to social vignettes to assess social information processing. Of note, the data collection was prematurely discontinued due to the emergence of the COVID-19 pandemic; therefore, results of the present study should be interpreted with caution due to low power. Hypothesis 1 was partially supported, such that emotion dysregulation significantly estimated reactive aggression regardless of reporter. Further, negative urgency significantly estimated reactive aggression when reported by parents, but not by teachers. Contrary to hypothesis 2, SIP did not significantly estimate proactive aggression, and no interaction between SIP and parenting behaviors was observed. However, inconsistent discipline did significantly estimate proactive aggression suggesting learning history and environment play an important role in proactive aggression. Finally, contrary to hypothesis 3, no indirect effect of emotion dysregulation on reactive aggression through negative urgency were observed; however, these results are inconclusive due to low power. Findings of the present results have significant implications for the way in which aggression is conceptualized, as well as clinical implications for the treatment of aggressive behavior among children with ADHD

The economic and innovation contribution of universities: a regional perspective

Universities and other higher education institutions (HEIs) have come to be regarded as key sources of knowledge utilisable in the pursuit of economic growth. Although there have been numerous studies assessing the economic and innovation impact of HEIs, there has been little systematic analysis of differences in the relative contribution of HEIs across regions. This paper provides an exploration of some of these differences in the context of the UK’s regions. Significant differences are found in the wealth generated by universities according to regional location and type of institution. Universities in more competitive regions are generally more productive than those located in less competitive regions. Also, traditional universities are generally more productive than their newer counterparts, with university productivity positively related to knowledge commercialisation capabilities. Weaker regions tend to be more dependent on their universities for income and innovation, but often these universities under-perform in comparison to counterpart institutions in more competitive regions. It is argued that uncompetitive regions lack the additional knowledge infrastructure, besides universities, that are more commonly a feature of more competitive regions

"Women's rights, the European Court and Supranational Constitutionalism"

This analysis examines supranational constitutionalism in the European Union. In particular, the study focuses on the role of the European Court of Justice in the creation of women’s rights. I examine the interaction between the Court and member state governments in legal integration, and also the integral role that women’s advocates – both individual activists and groups – have played in the development of EU social provisions. The findings suggest that this litigation dynamic can have the effect of fueling the integration process by creating new rights that may empower social actors and EU organizations, with the ultimate effect of diminishing member state government control over the scope and direction of EU law. This study focuses specifically on gender equality law, yet provides a general framework for examining the case law in subsequent legal domains, with the purpose of providing a more nuanced understanding of supranational governance and constitutionalism

Search for the Supersymmetric Partner of the Top-Quark in ppˉp \bar{p} Collisions at s=1.8TeV\sqrt{s} = 1.8 {\rm TeV}

We report on a search for the supersymmetric partner of the top quark (stop) produced in $t \bar{t}$ events using $110 {\rm pb}^{-1}$ of $p \bar{p}$ collisions at $\sqrt{s} = 1.8 {\rm TeV}$ recorded with the Collider Detector at Fermilab. In the case of a light stop squark, the decay of the top quark into stop plus the lightest supersymmetric particle (LSP) could have a significant branching ratio. The observed events are consistent with Standard Model $t \bar{t}$ production and decay. Hence, we set limits on the branching ratio of the top quark decaying into stop plus LSP, excluding branching ratios above 45% for a LSP mass up to 40 {\rm GeV/c}$^{2}$.Comment: 11 pages, 4 figure

Measurement of the B0 anti-B0 oscillation frequency using l- D*+ pairs and lepton flavor tags

The oscillation frequency Delta-md of B0 anti-B0 mixing is measured using the partially reconstructed semileptonic decay anti-B0 -> l- nubar D*+ X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992 - 1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb-1 of pbar p collisions at sqrt(s) = 1.8 TeV. We estimate the proper decay time of the anti-B0 meson from the measured decay length and reconstructed momentum of the l- D*+ system. The charge of the lepton in the final state identifies the flavor of the anti-B0 meson at its decay. The second lepton in the event is used to infer the flavor of the anti-B0 meson at production. We measure the oscillation frequency to be Delta-md = 0.516 +/- 0.099 +0.029 -0.035 ps-1, where the first uncertainty is statistical and the second is systematic.Comment: 30 pages, 7 figures.

Managing international branch campuses: what do we know? [forthcoming]

peer-reviewedOver the last decade, the growth of the international branch campus (IBC) has been one of the most striking developments in the internationalisation of higher education. There are now over 200 IBCs across the world, mostly in the Middle East and East and South‐east Asia. Despite the growing numbers of IBCs and the considerable financial and reputational risk they pose to their home universities, relatively little is known about the challenges of managing these foreign outposts. This paper reviews the growing, but still fragmented, literature in this increasingly important sector of higher education. It finds that managers of IBCs are faced with a range of challenges, which primarily stem from dealing with key stakeholder groups: students, staff, home and host country quality regulators, the home university and the host government, as well as the IBC's local joint venture partners. It concludes that further work is required to better understand the factors which influence and constrain IBC managers in balancing the competing interests of stakeholders.ACCEPTEDpeer-reviewe
