Quantifying Structural Attributes of System Decompositions in 28 Feature-oriented Software Product Lines: An Exploratory Study

Sobernig, Stefan; Apel, Sven; Kolesnikov, Sergiy; Siegmund, Norbert (2014)
Background: A key idea of feature orientation is to decompose a software product line along the features it provides. Feature decomposition is orthogonal to object-oriented decomposition it crosscuts the underlying package and class structure. It has been argued often that feature decomposition improves system structure (reduced coupling, increased cohesion). However, recent empirical findings suggest that this is not necessarily the case, which is the motivation for our empirical investigati...

Lenovo-IBM: Bridging Cultures, Languages, and Time Zones An Audacious Deal (A)

Stahl, Günter; Köster, Kathrin (2013)
The case describes the audacious acquisition of an American icon, IBM, by a Chinese computer manufacturer, Lenovo. The time frame spans from the pre-merger time until a few months after the IBM deal. In 2005, when Lenovo was the ninth largest PC maker in the world, it acquired IBM's PC business to become a global player in the PC industry. The case offers background information on the development of Lenovo, describes the Chinese company's approach to establish itself in the global market, and...

Regulation and Investment in Next Generation Access Networks: Recent Evidence from the European Member States

Briglauer, Wolfgang; Ecker, Georg; Gugler, Klaus (2012)
Fiber-deployment of future telecommunications networks ("Next Generation Access" - NGA) is currently a major challenge for sector-specific regulators as well as for investing firms. Although the future socio-economic importance of new telecommunications networks is uncontroversial, the related investment activities vary substantially in international comparison. This work intends to identify the most important determinants of previous NGA deployment using data from the EU27 mem...

Market structure and competition in the healthcare industry. Results from a transition economy

Lábaj, Martin; Silanic, Peter; Weiss, Christoph; Yontcheva, Biliana (2018)
The present paper provides first empirical evidence on the relationship between market size and the number of firms in the healthcare industry for a transition economy. We estimate market-size thresholds required to support different numbers of suppliers (firms) for three occupations in the healthcare industry in a large number of distinct geographic markets in Slovakia, taking into account the spatial interaction between local markets. The empirical analysis is carried out for th...

Combining Weighted Centrality and Network Clustering

Bohn, Angela; Theußl, Stefan; Feinerer, Ingo; Hornik, Kurt; Mair, Patrick; Walchhofer, Norbert (2009)
In Social Network Analysis (SNA) centrality measures focus on activity (degree), information access (betweenness), distance to all the nodes (closeness), or popularity (pagerank). We introduce a new measure quantifying the distance of nodes to the network center. It is called weighted distance to nearest center (WDNC) and it is based on edge-weighted closeness (EWC), a weighted version of closeness. It combines elements of weighted centrality as well as clustering. The WDNC will be tested on ...

What Determines the Quality of Job Training Services? A Multi-Level Analysis for Austria.

Trukeschitz, Birgit; Schneider, Ulrike (2008)
Within the last few decades, the provision of social services was and still is changing in many ways: due to ideological changes and cost containment efforts, the public sector has been gradually withdrawing from his dual role as financier and provider of social services. The public sector now prefers acting as a financier rather than a provider. It purchases services on behalf of service users, while private sector organizations assume the responsibility for service provision. Recently, Euro...

Im Projektmanagement hat bisher keine substantielle Auseinandersetzung mit den Prinzipien nachhaltiger Entwicklung stattgefunden. Derzeit arbeiten Expert(inn)en aus Nachhaltigkeitsforschung und Projektmanagement gemeinsam an einem konzeptionellen Rahmen, neuen Instrumenten und ersten Fallstudien.

Lenovo-IBM: Bridging Cultures, Languages, and Time Zones Integration Challenges (B)

Stahl, Günter; Köster, Kathrin (2013)
The focus of this case lies in the post-merger integration issues that Lenovo had to master in order to extract full value as well as synergies from its acquisition. The time span analyzed is from the merger until approximately one year after. The case describes the "Best of Both Worlds" integration approach adopted by Lenovo and the top management team's attempts to set aside egos and learn from each other, as well as to make decisions that are in the best interest of the new company, e.g., ...
