Linking Report Individualization and Report Standardization: A Configurational Perspective

Many organizations are facing the challenge that employees supplement their standardized Ac-counting Information Systems (AIS) with individually tinkered spreadsheets or other types of workaround systems. While such supplements provide employees with the flexibility to adjust the AIS to their individual preferences and to respond quickly to new opportunities, these sup-plements also cause adverse effects such as data redundancy, limited report reuse, loss of eco-nomic scale effects, and loss of compliance with regulatory and supervisory reporting require-ments. \ \ To provide organizations with a model for balancing report standardization and report individu-alization, I explore and analyse the AIS of four organizations. Specifically, I adopt a configura-tional perspective to examine two AIS use processes simultaneously: report standardization and report individualization. The resulting model indicates the need for an iterative approach which supports discussion and feedback on individualized reports and views individualized reports as prototypes for standardized reports. I conclude may work by discussing the value and limitations of the model and research design.

On Kaon production in e+e- and Semi-inclusive DIS reactions

We consider semi-inclusive unpolarized DIS for the production of charged kaons and the different possibilities to test the conventionally used assumptions s-\bar=0 and D_d^{K^+-K^-}=0. The considered tests have the advantage that they do not require any knowledge of the fragmentation functions. We also show that measurements of both charged and neutral kaons would allow the determination of the kaon FFs D_q^{K^++K^-} solely from SIDIS measurements, and discuss the comparison of (D_u-D_d)^{K^+-K^-} obtained independently in SIDIS and e+e- reactions. All analysis are performed in LO and NLO in QCD. The feasibility of the tests to HERMES SIDIS data is considered.Comment: 7 pages, NLO analysis for all presented tests and feasibility to HERMES data adde

Generativity of Business Intelligence Platforms: A Research Agenda Guided by Lessons from Shadow IT

To provide software platforms that are highly adjustable to users’ needs, recent literature proposes generativity, that is, platforms that may be supplemented in order to provide functionality that the designers of the platform did not have in mind. The research stream on generative platforms features a similar phenomenon as the research stream on shadow IT (SIT), because SIT also investigates supplements to integrated software-based systems that the designers of the software initially did not have in mind. Especially the domain of business intelligence (BI) is often flooded with SIT such as additional data marts and spreadsheets. However, while a wide body of literature has emerged that investigates SIT impacts, few, if any, studies examined generativity of platforms in general and BI platforms specifically. In this paper we present a literature review on positive and negative SIT impacts. Building on the results, we suggest a research agenda on generativity of BI platforms

Which are the Most Effective Measures for Improving Employees’ Security Compliance?

Employees’ compliance behavior with information security policies has been extensively researched yet. In particular, many studies identified and explained measures that increase employees’ security compliance such as trainings and controls. Although the identification and explanation of these measures is valuable for managers, these findings are insufficient. Since managers need to balance limited resources, they need to be able to prioritize and invest in the most effective measures for improving employees’ security compliance. Therefore, to complement extant research, we survey 332 employees in an organization that has established 15 security measures. Our results provide managers with a quantitative assessment of these 15 security measures. Furthermore, we discuss its implications and provide five specific recommendations for managers. Besides, results may also be valuable for theorists because they show which types of security trainings are perceived by employees to be more effective than others

Designing Social Nudges for Enterprise Recommendation Agents: An Investigation in the Business Intelligence Systems Context

According to behavioral economists, a “nudge” is an attempt to steer individuals toward making desirable choices without affecting their range of choices. We draw on this concept, and design and examine nudges that exploit social influence’s effects to control individuals’ choices. Although recommendation agent research provides numerous insights into extending information systems and assisting end consumers, it lacks insights into extending enterprise information systems to assist organizations’ internal employees. We address this gap by demonstrating how enterprise recommendation agents (ERAs) and social nudges can be used to tackle a common challenge that enterprise information systems face. That is, we use an ERA to facilitate information (i.e., reports) retrieval in a business intelligence system. In addition, we use social nudges to steer users toward reusing specific recommended reports rather than choosing between recommended reports randomly. To test the effects of the ERA and the four social nudges, we conduct a within-subject lab experiment using 187 participants. We also conduct gaze analysis (“eye tracking”) to examine the impact of participants’ elaboration. The results of our logistic mixed-effects model show that the ERA and the proposed social nudges steer individuals toward certain choices. Specifically, the ERA steers users toward reusing certain reports. These theoretical findings also have high practical relevance and applicability: In an enterprise setting, the ERA allows employees to reuse existing resources (such as existing reports) more effectively across their organizations because employees can more easily find the reports they actually need. This, in turn, prevents the development of duplicate reports

Possible Explanations for the NuTeV Weinberg Angle Measurement

The NuTeV collaboration has made an independent determination of the Weinberg angle by measuring charged and neutral-current cross sections from neutrino and antineutrino DIS on iron. Their value differs by 3 standard deviations from that obtained from measurements at the Z pole. We review this experiment and assess various possible explanations for this result, both within the Standard Model ("old physics") and outside the Standard Model ("new physics").Comment: QCD Down Under Workshop, CSSM, Adelaide, Australia, Mar 10-19, 2004; 6 pages, 3 figs; updated references on QCD effect

The Effect of Recommender Systems on Users’ Situation Awareness and Actions

Many organizations are implementing recommender systems with the expectation to influence users’ actions. However, research has shown that poorly designed recommender systems may be counterproductive. For instance, if a recommender system provides too many recommendations, users cannot focus on relevant recommendations anymore. To tackle this challenge, recommender systems need to be balanced and adjusted to the processes in which they shall support users. Only designed correctly, recommender systems may influence users’ situation awareness and, ultimately, enable them to perform informed actions. Research has shown that users’ situation awareness depends on users’ elaboration. Therefore, we draw on the Elaboration Likelihood Model to conceptualize recommendation velocity and recommendation faithfulness as two variables that influence users’ situation awareness. Furthermore, since research identified process automation as a major antecedent of situation awareness, we conceptualize process automation as a third influencing variable. Finally, we develop a conceptual research model and outline our next steps

Design Principles for Diffusion of Reports and Innovative Use of Business Intelligence Platforms

In order to innovate and respond quickly to new requirements, employees frequently supplement their information systems. This particularly applies to the context of business intelligence (BI) because many users supplement their BI platforms with individually tinkered spreadsheets. Unfortunately, these supplements bear numerous threats such as limited report reuse across all potential users. To address this gap, we establish a design science project. First, we qualitatively explore impediments to diffusion of reports and impediments to innovative use. Second, upon our findings and extant literature, we derive meta-requirements for BI platforms that foster diffusion of reports and innovative use. Third, we develop and discuss principles for how to design a BI platform that would meet the identified meta-requirements. The resulting design principles emphasize (1) permanent user sandboxes to improve innovative use and (2) hybrid recommendation agents based on user interaction, collaborative-filtering, and users\u27 social influence to improve diffusion of reports

Soft-Gluon Resummation for Heavy Quark Production in Charged-Current Deep Inelastic Scattering

We study soft-gluon radiation for heavy quark production in charged-current Deep Inelastic Scattering processes. We resum large-x contributions to the MSbar coefficient function to next-to-leading logarithmic accuracy and present results for charm quark structure functions for several values of the ratio m_c/Q. The effect of the resummation turns out to be visible, especially at small Q^2, and the results exhibit very little dependence on factorization and renormalization scales. The impact of our calculation on structure function measurements at NuTeV and HERA experiments is discussed.Comment: 21 pages, 7 figure

Polarized Parton Distribution in Neutrino Induced Heavy Flavor Production

In order to examine polarized strange quark distribution, semi-inclusive D/\Dbar production in neutrino deep inelastic scattering is studied including ${\cal O}(\alpha_s)$ corrections. Cross section and spin asymmetry are calculated by using various parametrizations of polarized parton distribution functions. It is found that \Dbar production is promising to directly extract the polarized strange sea.Comment: 3 pages, 2 figures. Talk given at the NuFact02 workshop, London, UK, July 1-6, 200
