This paper studies optimal divestment policy of an investor in a …rm that may partially and gradually divest its capital or sell the whole …rm at once. Partial divestment o¤ers greater ‡exibility while a whole-…rm transaction provides a price premium. We show that, if the price premium includes both a …xed and a proportional component, a large …rm optimally starts to divest partial capital befo...

Governance für effektive serviceorientierte Architekturen – Eine empirische Studie in der deutschen Dienstleistungswirtschaft" (2011). auf die Effektivität von SOA deutlich.

Attentional threat bias (ATB) has been suggested as one factor leading to maintenance and exacerbation of posttraumatic stress symptoms (PTSS). In the present study, attentional processes (i.e., facilitated engagement, difficulty disengaging) underlying the association between ATB and PTSS were examined. Additionally, attentional control (AC) was examined as a moderator of this relationship. Pa...

Im Hinblick auf sich verändernde Marktbedingungen und die damit verbundenen Flexibilitätsanforderungen ist die effiziente Steuerung und Kontrolle von IT-Systemen auf Basis Service-orientierter Architekturen (SOA) primäres Ziel von SOA-Governance-Frameworks. Die Einführung und Anwendung, d.h., die Bewertung von Prozessen hinsichtlich best-practice-Frameworks, ist in der Regel aufwändig und resso...

L. Walker This paper discusses the use of service-oriented architecture (SOA) as one of the key elements supporting business transformation at IBM. It describes the internal SOA strategy, SOA governance, organizational impacts, and several IBM internal SOA case studies. The top-down and bottom-up approaches to promoting SOA within the enterprise are also illustrated, along with a set of SOA bus...

Field measurements of secondary organic aerosol (SOA) find significantly higher mass loads than predicted by models, sparking intense effort focused on finding additional SOA sources but leaving the fundamental assumptions used by models unchallenged. Current air-quality models use absorptive partitioning theory assuming SOA particles are liquid droplets, forming instantaneous reversible equili...

Recently, Service-Oriented Architecture (SOA) has received significant attention. SOA simulation can play an important role in SOA software development as it can be used to verify the SOA application models and to demonstrate runtime and collaborative behaviors of the SOA applications. SOA simulation differs from traditional simulation as it emphasizes on reusability, collaborative behaviors, a...

In this paper first we try to analysis the behavior ofthe SOAs in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. After that by employing thismodel as inline amplifier for a DWDM optical system, we havesimulated the transmission of 10 channels with bit rate 10 Gb/sup to distance 3970 km with RZ-DPSK modulation ...

To support the difficult process of SOA adoption, SOA maturity models are published. In this thesis a literature analysis introduces the area of SOA maturity models and highlights benefits and criticism. As a result, the combined SOA maturity model (CSOAMM), a model to facilitate the interpretation and comparison of SOA maturity models, is proposed. CSOAMM is a model with 10 levels that describ...
