Core concepts for share vectors

A value mapping for cooperative games with transferable utilities is a mapping that assigns to every game a set of vectors each representing a distribution of the payoffs. A value mapping is efficient if to every game it assigns a set of vectors which components all sum up to the worth that can be obtained by all players cooperating together.? An approach to efficiently allocate the worth of the ‘grand coalition’ is using share mappings which assign to every game a set of share vectors being vectors which components sum up to one. Every component of a share vector is the corresponding players' share in the total payoff that is to be distributed among the players. In this paper we discuss a class of share mappings containing the (Shapley) share-core, the Banzhaf share-core and the Large Banzhaf share-core, and provide characterizations of this class of share mappings.

Graphs with small balanced decomposition numbers

A balanced coloring of a graph \(G\) is an ordered pair \((R,B)\) of disjoint subsets \(R,B \subseteq V(G)\) with \(|R|=|B|\) . The balanced decomposition number  \(f(G)\) of a connected graph \(G\) is the minimum integer \(f\) such that for any balanced coloring \((R,B)\) of \(G\) there is a partition \(\mathcal{P}\) of \(V(G)\) such that \(S\) induces a connected subgraph with \(|S| \le f\) and \(|S \cap R| = |S \cap B|\) for \(S \in \mathcal{P}\) . This paper gives a short proof for the result by Fujita and Liu (2010) that a graph \(G\) of \(n\) vertices has \(f(G)=3\) if and only if \(G\) is \(\lfloor \frac{n}{2} \rfloor \) -connected but is not a complete graph.     

Getting What You Pay For—Strategic Process Improvement Compensation and Profitability Impact

Profit‐maximizing firm owners who incentivize their managers with a bonus for process improvement create an intentional misalignment of their own objective and management attention. From the viewpoint of a single firm, such a local misalignment can never be profitable, but in this study we take a wider strategic perspective by investigating cost‐reducing process improvements of two firms competing in a Cournot market. We find that the use of a process improvement bonus (by firm A) can be profitable, by affecting the competitor's decision making. Informed about the reward structure at firm A, which provides an incentive for process improvement and thereby for increased production at that firm, the manager of the competing firm (B) is inclined to produce less if the owner of firm B only rewards profit. This leads to a higher profit for firm A. However, we also show that firm B's best strategy is to also offer a process improvement bonus, even if that firm is a cost laggard (with higher costs for process improvement), and that this leads to reduced profit for both firms in many situations unless one of them is sufficiently superior in its ability to improve processes. These results are robust for uncertain process improvement outcomes, multidimensional process improvement decisions, and information asymmetry in the owner–manager relationship.     

Shareholders’ Voting at General Meetings: Evidence from the Netherlands

We study annual general meetings of shareholders in the Netherlands. The Dutch corporate governance system is characterized by relatively concentrated shareholdings and large stakes owned by pension funds, banks and insurance companies. The legal protection of shareholders is poor due to the presence of takeover defenses, such as certificates, which deprive shareholders from their voting rights. An analysis of the minutes of 245 general meetings in the period 1998–2002 reveals that on average 30% of the equity capital is represented at the meeting. All proposals at the meeting are sponsored by the management and only 9 out of 1,583 proposals are rejected or withdrawn. Our analyses show that pension funds are the most active and critical shareholders at the meetings, while certificates effectively restrict shareholder rights. Our main conclusion is that the general meetings do not provide shareholders in the Netherlands any significant influence on management.     

From Ethnic segregation to impact integration: state schooling and identity construction for rural Tibetans

This paper examines the context of ethnic identity formation in schools for rural Tibetan children. It reviews rural primary education within Tibet and the secondary education for Tibetans in boarding schools across China. Data are presented on policies, student recruitment, curriculum, teachers and the campus environment, as they impact on students' identity formation. Although there is little that is multicultural about the learning process in these schools, these schools do not strictly deny Tibetan culture to Tibetan children. The school architecture, sculptures, photographs, wall paintings and so forth provide representations of Tibetan culture, albeit selectively and interpreted by the state in terms of the ideological themes of national unity, patriotism, revolutionary traditions, civilised behaviour and love of Tibet. The conclusion points to a make‐or‐break opportunity for state education to support a more even‐handed cultural policy, rather than the dichotomy of segregation and impact integration.     

Interparental Hostility and Early Adolescent Problem Behavior: The Mediating Role of Specific Aspects of Parenting

This study examines how parenting helps explain the contemporaneous association between interparental hostility and adolescent problem behavior. A theoretical model of spillover was tested specifying five aspects of mothers' and fathers' parenting that might be associated with parents' hostile interactions with one another: harshness, inconsistency, psychological intrusiveness, and lower levels of acceptance and monitoring knowledge. The sample consisted of 416 early adolescents and their married parents. The association between interparental hostility and adolescent externalizing problems was mediated uniquely by fathers' and mothers' harshness, lower levels of fathers' monitoring knowledge, and mothers' psychological intrusiveness. The association between interparental hostility and adolescent internalizing was mediated uniquely by mothers' harshness, psychological intrusiveness, and lower levels of acceptance. These patterns were similar for sons and daughters.     

Child Sexual Abuse and Psychological Impairment in Victims: Results of an Online Study Initiated by Victims

Sexual abuse of children has been a topic of scientific investigation for the past few decades. Research in this area, however, is rarely initiated, conceptualized, and conducted by victims themselves. Apart from possibly having painted a one-sided picture of sexual abuse, this presumed dominance of nonvictims might also have marginalized victims in a research area central to their lives. This study was conducted by a victims interest group as an effort to meet the need to add victims' perspectives to our current understanding of this topic. The online survey focused on investigating victims' psychosocial impairment, which was found to be extensive. Results indicated that an intact social support system facilitates better health, especially when offered early on.     

Extending the Foundations and Reach of Design Science: Further Reflections on the Role of Critical Realism

In his commentary on our proposal to reframe the relevance of business and management research by combining design science with critical realism (Hodgkinson and Starkey, British Journal of Management, 22 (2011), pp. 355–369), Willmott (British Journal of Management, 23 (2012), pp. 598–604) commends us for our advocacy of a social science as opposed to professional school agenda, while admonishing us for seeking to underpin the commended design science ethos with critical realism, on the grounds of ontological inconsistency and the risk of diminishing the emancipatory elements of our social usefulness agenda. In reply, we demonstrate how, in highlighting the interplay of multiple generative mechanisms within and between levels of analysis, critical realism is entirely commensurate with the design science approach advocated, and enriches rather than diminishes our overarching agenda to humanize the workplace.
