Exploring PMOs through community of practice theory

This article explores project management offices (PMOs) through community of practice theory. Preliminary results from a national health care case study are used to confirm the legitimacy of this approach. Today's knowledge‐based economy calls for mechanisms to share knowledge. The issue of making more with less is at stake in order to reuse good practices, support innovative practice, and prevent the reinvention of the wheel. Members of these communities are at the heart of the learning process. The originality of this research is that it sheds light on PMOs in a new theoretical perspective within the field of knowledge management.     

When Organizational Justice Matters for Affective Merger Commitment

We investigate when organizational justice matters to employees’ commitment in the postacquisition process after a company is taken over in a cross‐border acquisition. Overwhelming evidence from the literature suggests that employees who are treated fairly during acquisitions are more committed to their new firms. We extend this finding by dividing organizational justice into three subdimensions: informational justice, interpersonal justice, and procedural justice. We find evidence that procedural justice is an important antecedent of affective merger commitment at an early stage of the integration period, while informational justice becomes important at a later stage. Further analysis on heterogeneity between the target firm's employees and the bidder firm's employees reveals that, immediately after the acquisition, target firm's employees value knowing where they will be at the new firm (procedural justice), while bidder firm employees are more concerned about communication and transparency (informational justice). Our results point to the importance of organizational justice in a cross‐border merger and acquisition (M&A) setting and the need for a separate study of issues related to bidder firms and target firms. © 2016 Wiley Periodicals, Inc.     

Portfolio optimization based on GARCH-EVT-Copula forecasting models

This study uses GARCH-EVT-copula and ARMA-GARCH-EVT-copula models to perform out-of-sample forecasts and simulate one-day-ahead returns for ten stock indexes. We construct optimal portfolios based on the global minimum variance (GMV), minimum conditional value-at-risk (Min-CVaR) and certainty equivalence tangency (CET) criteria, and model the dependence structure between stock market returns by employing elliptical (Student-$t$ and Gaussian) and Archimedean (Clayton, Frank and Gumbel) copulas. We analyze the performances of 288 risk modeling portfolio strategies using out-of-sample back-testing. Our main finding is that the CET portfolio, based on ARMA-GARCH-EVT-copula forecasts, outperforms the benchmark portfolio based on historical returns. The regression analyses show that GARCH-EVT forecasting models, which use Gaussian or Student-$t$ copulas, are best at reducing the portfolio risk.     

Sustainability practices of family firms: the interplay between family ownership and long-term orientation

Sustainability practices are critical for family firms, as they relate directly to the continuity of the business and relationships with important stakeholders, such as members of the local community. Nevertheless, not all family firms wish to adopt sustainability practices. To examine this, we draw upon the socioemotional wealth perspective in order to develop a theoretical model of the direct negative effects of family ownership on the adoption of sustainability practices. We also suggest moderating effects of long-term orientation (LTO) on this link. Our model is tested on a sample of 195 family firms in the tourism and hospitality sector. The results support our hypothesis that family ownership negatively influences the adoption of sustainability practices. Additionally, LTO moderates the relationship between family ownership and the adoption of sustainability practices, such that family owners with a high LTO are more likely to adopt this particular practice compared to those with a low LTO.     

The EU’s new competition policy standards

In a 2008 article in the EU’s Competition Policy Newsletter, Peter Lowe, Director General of the EU Commission’s Directorate Competition, synthesised the experience of his office with regard to the design of competition policy institutions for the 21st century. A year earlier, he had co-authored another article, appearing in the same venue, recapitulating the Commission’s lessons learned from the Energy Sector Inquiry and the need for effective unbundling of energy transmission networks. The reader of both, at first astounded by the apparent gap between policymaking reality and reflections upon it, soon detects a rather pragmatic approach to shaping regulatory agendas. But are there limits to expediency?     

Pflegeberatung ist Vertrauenssache

M?ngeln in der h?uslichen Pflege pr?ventiv begegnen – Vertrauen ohne Kontrolle, Routine, überforderung oder das Nichtbeachten des Beziehungsgeflechtes zwischen Pflegenden und Gepflegten führt oft zu Problemen. Der Gesetzgeber verpflichtete deshalb die Pflegekassen und Tr?gerverb?nde von ambulanten Pflegeeinrichtungen zur Erarbeitung von Richtlinien und standardisierten Verfahren für die Pflegefachberatung. Leider gibt es bislang keine verbindliche Umsetzung.     

Rationierung: Teufelszeug oder Herausforderung zum Umdenken?

Umgang mit knappen Ressourcen - Das Schreckgespenst der Rationierung macht sich im Gesundheitswesen breit und beunruhigt Patienten, Anbieter von Gesundheitsleistungen und den Gesetzgeber gleicherma?en. Pflegende befürchten, selbst Opfer oder Henkersknechte dieses Ph?nomens zu werden. Sind diese ?ngste begründet? Und – besteht die M?glichkeit zum Gegensteuern? Eine kritische Einsch?tzung von Ralf Gratias.     

Teaching Interactive Media Design

In todays, computer-centered society, designing interactive media has emerged as a new profession. Interactive design is often associated with spread of computers as a communication and interaction tool. However, interactive design has been a staple of artists and designers for many centuries. We present a historical perspective upon interactive design and point out the close relationship of this field with different fields of art and design. We argue that interactive media design is a distinct and evolving field and that it is imperative to teach it as such. In this paper, we have adopted this perspective and detailed a new four-year under-graduate curriculum on interactive media design education. This curriculum stresses the various components of interactive media design and its close relationship with computer science. This revised version was published online in July 2006 with corrections to the Cover Date.
