The use of ICT in the Austrian judicial system can be described as widespread. Currently, a plethora of different benchmarking studies have been published ranking different countries according to their e-government readiness or maturity, but they are inconclusive, so no results are given here. For discussion of these studies, see for example Lee, Tan and Trimi (2005) or Ostermann and Staudinger (2005). An overview of the technologies in use, which also covers the general organisation of the judicial system in Austria, can be found in ...

ABSTRACT Motivated by information technology evaluation problems identified in a large public sector organization, we propose how evaluation requirements can be supported by a framework combining different models andmethods from information systems evaluation theory. The article extends the content, context, process perspectives of organizational change with operations research techniques and demonstrates the approach in practice for an Enterprise Resource Planning evaluation.

ABSTRACT Die Symptomatik einer Depression ist durch reduzierte emotionale Schwingungsfähigkeit, negative Kognitionen, sozialen Rückzug und negatives Selbstwerterleben charakterisiert. Es wird eine erhöhte Reaktivität auf negative Stimuli (negative potentiation) bzw. eine reduzierte Sensitivität auf den emotionalen Kontext (emotion context insensitivity) angenommen (z.B. Peeters et al., 2010). Ziel dieser Studie ist die Untersuchung der Stabilität bzw. Instabilität von Affekt und Selbstwerterleben bei Depression mittels Ambulantes Assessment im Kontext der stationären psychotherapeutischen Behandlung. Geplant ist die Rekrutierung von 50 Patientinnen der Schön-Klinik Roseneck (Prien am Chiemsee) mit mindestens mittelgradiger depressiver Episode (ICD-10 F32.1/.2 bzw. F33.1/.2), welche über einen viertägigen Zeitraum mit elektronischen Tagebüchern ausge-stattet werden. Dabei werden mehrfach täglich in Alltagssituationen das Selbstwerterleben mit einer Kurzform der Rosenberg Self Esteem Scale (SES) und die momentane Stimmung mit einer Kurzform des Mehrdimensionalen Befindlichkeitsfragebogens (MDBF) erfasst. Als Vergleichsgruppen dienen bereits vorliegende Daten von 46 Patientinnen mit Borderline-Persönlichkeitsstörung (ZI Mannheim) und 57 gesunden Kontrollen (KIT Karlsruhe). Es werden das laufende Projekt und erste Ergebnisse vorgestellt. Ambulantes Assessment bieten wesentliche Vorteile gegenüber möglicherweise bei der Un-tersuchung von Depressionen besonders relevanten Verzerrungen retrospektiver Selbstein-schätzungen (Ebner-Priemer & Trull, 2009; 2013). Neben der Untersuchung zentraler auf-rechterhaltender Faktoren der Depression erlaubt die vorliegende Studie die Erprobung von Ambulantem Assessment unter stationären Routinebedingungen.

This article strives to support research and practice in the application of decision and valuation models to IT infrastructure projects in public administration. The aim is to present the elements needed to flexibly embrace evaluation structure, management and quantification methods. We sketch how different models can work together in a complementary way laying a robust and comprehensive foundation for an integrated analysis of IT impacts. We present design and assessment results from two major IT ...

This study addresses the complex relationship between decision making for ERP investments and the consideration of organizational impact under 2 different perspectives: Enterprise Resource Planning (ERP) system decisions in organizations with Business Process Improvement (BPI) in particular Business Process Reengineering (BPR) efforts and ERP decisions without BPI/BPR efforts. On the basis of a questionnaire sent to 813 austrian middle und large scale organizations, this paper shows that companies have weighted the ...

The distally based rectus abdominis myocutaneous flap is used in a new technique for vaginal reconstruction after pelvic exenteration for malignant disease. We identified 27 patients who underwent this procedure, of whom eight had a total of 14 postoperative CT scans and two CT-directed biopsies. The myocutaneous flap appeared as a unilateral arcuate band of soft tissue extending from the linea alba to the rectal fascia or sacrum. Additional CT findings included asymmetric thinning of the ventral abdominal wall (7/8), fluid collections (2/8), vaginal breakdown (1/8), presacral soft-tissue thickening (6/8), and tumor recurrence (3/8). The postoperative CT scan reflects the altered anatomy produced by the surgery. Complications and recurrent disease can be recognized as deviations from the normal postoperative appearance.
