In this study, we apply several recently proposed models to the evolution of secondary organic aerosols (SOA) and organic gases advected from downtown Mexico City at an altitude of ∼3.5 km during three days of aging, in a way that is directly comparable to simulations in regional and global models. We constrain the model with and compare its results to available observations. The model SOA form...

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...
