- The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.

- We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

A Method for Context Modelling in Capability Management

Konferensbidrag (refereegranskat)abstract
- Enterprises exist in the context of their dynamically changing environment, which has a strong impact on service design and delivery. Within areas such as ambient intelligence or robotics, most relevant context has a physical nature. However, the context of an enterprise requires a different conceptual-ization of context awareness. Beyond physical context, enterprises need to be aware of their market, legal and social context. Moreover, in order to monitor context and configure services systematically, we need a context modelling method that is integrated within enterprise modelling and supports in-formation and communication technology (ICT) engineering and runtime. The work in this paper has been performed as part of developing Capability Driven Development (CDD), a new paradigm for ICT design where services are customised on the basis of the essential business capabilities and deliv-ery is adjusted according to the current context. The contributions of the paper are (i) the investiga-tion of industrial needs for context modelling, (ii) eCoM, a context modelling method for enterprise ICT addressing such needs, iii) application of the method in an industrial use case and (iv) the evolu-tion of eCoM based on various evaluation cycles by means of Framework for Evaluation in Design Science Research (FEDS).

- Technological advances, changes in regulations and increasing globalization of the economy demand high adaptability from enterprises in many areas. Enterprise Architecture Management provides organizations with an integrated view enabling such adaptability. In this respect, development and management of the capabilities receive attention, as the term is associated with flexibility, dynamics and variation. On the contrary, little effort has been put towards developing and modeling capabilities. This chapter focuses on the Capability-Driven Development (CDD) method, which is a novel approach for designing capabilities to tackle the challenges of rapidly changing enterprise environments by modeling the application context. The results presented in this chapter are (i) a description of the state of research in capability development methods, (ii) a component-wise structured capability modeling method based on business processes, goals and concepts of an enterprise, (iii) a demonstration of the method application in a use case from the utilities industry and (iv) observations made during the capability development and strategy use.

Synergising Management Systems : Framework and Application in Regulative Compliance

Konferensbidrag (refereegranskat)abstract
- When introducing new management systems and regulatory requirements, companies often have to change and adapt their operational and organisational structure, which usually leads to considerable work and costs. As there exist a plethora of different management systems and regulatory requirements, organisations need a systematic approach to avoid isolated implementations at operational level. In this context, we use a design science research approach to design a framework that identifies intersections between management systems and supports their implementation. Results of a literature analysis reveal similarities between management systems and enterprise architecture management concepts that influence the framework’s design. Our main contributions are (i) a literature review that identifies similarities of management systems, (ii) a framework that systematically identifies synergies among various management systems and provides means how to put them into practice, and (iii) the framework’s application in a use case in the domain of regulative compliance in banking.

- Eine hohe Dynamik in der Gesetzgebung, kurze Fristen und ansteigende organisatorische Auswirkungen machen die Umsetzung eines ganzheitlich integrierten Governance-, Risk- und Compliance-Ansatzes immer anspruchsvoller für Kreditinstitute. Bislang existieren weder ein adäquater Industriestandard noch nutzbare Referenzmodelle, die Compliance-Beauftragte bei der regulativen Compliance unterstützen. Dieser Artikel stellt ein Referenzmodell vor, welches sich die Realisierung einer ganzheitlichen Compliance zum Ziel setzt. Die Autoren präsentieren die Referenz-Compliance-Organisation, welche im Rahmen eines Bitkom-Forschungsprojektes die Realisierung einer integrierten und IT-gestützten Compliance ermöglichen soll.

- Die in diesem Aufsatz dargestellten Arbeiten entstanden im Projekt KOSMOS, das sich zum Ziel gesetzt, ein Konzept für das Lebenslange Lernen zu implementieren, in dessen Rahmen traditionellen und nicht-traditionellen Zielgruppen maßgeschneiderte Studienmöglichkeiten auf universitärem Niveau angeboten werden. Neue Studienformate ermöglichen die Aufnahme eines Studiums in allen Lebensphasen. Der Aufsatz konzentriert sich im Umfeld von KOSMOS auf die Frage, wie eine geeignete IT-Unterstützung für neue Zielgruppen und Studienformate aussehen muss. Die zentrale Idee ist ein kontextorientiertes informationstechnisches Portal für das e-Learning. Das Ergebnis ist das „MeinKOSMOS“ Portal mit einer individualisierten und bedarfsgerechten Informationsversorgung für die Lernenden. Der Beitrag beschreibt das Konzept für das Portal und Erfahrungen aus dessen Realisierung. Ein wichtiger Bestandteil ist dabei ein Leitfaden zur Bewertung, ob MeinKOSMOS für ein Studienformat geeignet ist bzw. wie das Portal dafür anzupassen ist.
