Lust an der Macht – Frauen in Organisationen

Storyline and analysis of the film “The Devil Wears Prada” provide vivid scenes to derive reflections on organisational culture in globalised companies and women in chief positions. Women come into conflict with leading the company successfully, the dependence on efficient – female – staff and the image as a woman. The article illustrates, how influences of the company’s products fashion und fashion market have a normative effect, especially on female staff members. Theories of organisational culture, careers of women and findings of gender research are shown in connection with complex strategies of women in their determination to succeed, to self-realization and the pressure to adapt oneself. This involves reflected perspectives to leave clichés of gender and to reinforce organisational and personal potentials.     

Arbeitszufriedenheit und Energie

Focussing on energy as a highly activated affective state offers new opportunities to promote well-being at work and job performance. In this paper, I will describe current research on recovery, affective work events and characteristics of work tasks linked to energy. The practical implications for promoting energy at work are discussed.     

Minimizing the number of tardy jobs in two-machine settings with common due date

We consider two-machine scheduling problems with job selection. We analyze first the two-machine open shop problem and provide a best possible linear time algorithm. Then, a best possible linear time algorithm is derived for the job selection problem on two unrelated parallel machines. We also show that an exact approach can be derived for both problems with complexity \(O(p(n) \times \sqrt{2}^n)\), p being a polynomial function of n.     

The thickness of the complete multipartite graphs and the join of graphs

The thickness of a graph is the minimum number of planar spanning subgraphs into which the graph can be decomposed. It is known for relatively few classes of graphs, compared to other topological invariants, e.g., genus and crossing number. For the complete bipartite graphs, Beineke et al. (Proc Camb Philos Soc 60:1–5, 1964) gave the answer for most graphs in this family in 1964. In this paper, we derive formulas and bounds for the thickness of some complete k-partite graphs. And some properties for the thickness for the join of two graphs are also obtained.     

Parameterized algorithms for min–max 2-cluster editing

For a given graph and an integer t, the Min–Max 2-Clustering problem asks if there exists a modification of a given graph into two maximal disjoint cliques by inserting or deleting edges such that the number of the editing edges incident to each vertex is at most t. It has been shown that the problem can be solved in polynomial time for \(t<n/4\), where n is the number of vertices. In this paper, we design parameterized algorithms for different ranges of t. Let \(k=t-n/4\). We show that the problem is polynomial-time solvable when roughly \(k<\sqrt{n/32}\). When \(k\in o(n)\), we design a randomized and a deterministic algorithm with sub-exponential time parameterized complexity, i.e., the problem is in SUBEPT. We also show that the problem can be solved in \(O({2}^{n/r}\cdot n^2)\) time for \(k<n/12\) and in \(O(n^2\cdot 2^{3n/4+k})\) time for \(n/12\le k< n/4\), where \(r=2+\lfloor (n/4-3k-2)/(2k+1) \rfloor \ge 2\).     

Characterizations of <Emphasis Type="Italic">k</Emphasis>-cutwidth critical trees

The cutwidth problem for a graph G is to embed G into a path such that the maximum number of overlap edges (i.e., the congestion) is minimized. The investigations of critical graphs and their structures are meaningful in the study of a graph-theoretic parameters. We study the structures of k-cutwidth \((k>1)\) critical trees, and use them to characterize the set of all 4-cutwidth critical trees.     

Executive remuneration standards and the “conformity gap” at controlled corporations

In this paper we analyze the relationship between conformity to executive remuneration standards, corporate ownership, and the level and structure of CEO compensation for large European listed companies in the years 2007 and 2010. We show that controlled corporations conform to executive remuneration standards less than widely held firms. We also show that weaker compliance is associated with lower CEO pay and more cash-based incentive structures. We interpret this “conformity gap” from the perspective of individual firms and from a societal perspective, with the aim to contribute to frame the policy questions concerning executive pay at controlled corporations. Different policy implications depend on whether the conformity gap reflects a lower need for managerial incentives, given the monitoring by controlling shareholders, or the latter’s willingness to extract private benefits of control. We argue in this paper that the former hypothesis prevails, so that regulators should abstain from increasing the level of enforcement of executive remuneration standards.     

The Global Wave of Refugees and Migrants: Complex Challenges for European Policy Makers

This article reviews the burdensome problem posed by the arrival in the European countries of large number of refugees and migrants from countries at war or with little economic opportunities. It differentiates the issues of migrants (for economic reasons) and refugees (humanitarian grounds). This wave of refugees currently poses huge challenges to European policy makers. The article suggests some policy initiatives that could solve or at least control the present chaos, disorder, and uncertainty created by the arrival of this unprecedented number of refugees.     

Organisation of new product development in Asia and Europe: results from Western multinationals R&amp;D sites in Germany,India, and China

From research on Western new product development (NPD) practices a rich body of literature has emerged. However, the impact of country specific and cultural influences has not been examined in this context yet. This study is a first attempt to identify differences in NPD practices between Research and Development (R&D) subsidiaries in Germany, China and India within multinational companies. Data has been generated by qualitative interviews with R&D executives in those countries across multiple cases. The study samples strategic, organizational and operational aspects indicates definite differences in process coordination, rewarding systems, market orientation and the average age of NPD teams. Other aspects like strategic targets, the management involvement, etc. show rather slight differences across the countries. Hence, findings suggest that while some aspects are universally applicable across cultural frontiers, Western companies have to understand different expectations regarding NPD in India and China by adjusting practices accordingly.     

Influential factors and performance of logistics outsourcing practices: an evidence of malaysian companies

Despite the growing trend of logistics outsourcing, there are very limited sources of literature on logistics outsourcing, especially in determining the relationship between factors influencing outsourcing and the extent of logistics outsourcing practices. In this study, we tap into the field of strategic management to help clarify the mechanisms underlying the links between factors influencing, logistics outsourcing practices and outsourcing performance. A model based on the resource based view illustrates the hypothetical connections among these variables. The data gathered from the survey were analysed using SmartPLS software. A response rate of 21 % out of the 486 firms selected was achieved and fixed as the empirical data for this study. The results of this study provide support that superior performance is correlated to the resources of the firm. The analysis shows that lack of human and physical asset capabilities, as well as transaction uncertainty influence the extent of different logistics outsourcing practices. The four logistics outsourcing practices under study were found to have a positive relationship with logistics outsourcing performance, particularly strategic focus. This study shows that although theoretically firms aim at cost reduction by employing a logistics outsourcing strategy but not proven in this study because the financial benefit was only positively contributed by one of the four logistics outsourcing practices under study. Besides that, the results from this study also support that most firms outsource their non-core activities of the logistics practices to respond to the transaction uncertainty that their business experiences.
