Increasing Returns and Social Contagion in Cultural Industries

A formal definition of cultural industries is developed following four distinct features of cultural goods: (a) oversupply, (b) quality uncertainty, (c) network effects and (d) demand reversal. Drawing on economic and socio-psychological notions of ‘network’, increasing returns and social contagion effects are distinguished. Increasing returns may govern the adoption of standards when choices are binary, social contagion explains the diffusion of cultural goods when choices are multiple. Together, the four structural features delineating cultural industries account for curious competitive dynamics prevalent in cultural markets, such as the notorious 10 : 90 proportionality (under which 10% of cultural goods account for 90% of the market), causal ambiguity about the reasons for success, and the formation of fashions. Six managerial recommendations are advanced, focusing on a criticial circulation point triggering self-sustaining diffusion patterns. Finally ‘project-based enterprises’ and ‘network forms of governance’ are identified as the organizational forms most suited to the dynamics of the cultural markets.     

The geometry of Gaussian double Markovian distributions

Gaussian double Markovian models consist of covariance matrices constrained by a pair of graphs specifying zeros simultaneously in the matrix and its inverse. We study the semi-algebraic geometry of these models, in particular their dimension, smoothness, and connectedness as well as algebraic and combinatorial properties.     

Explaining Native‐Migrant Differences in Parental Knowledge about the German Educational System

To make sound educational decisions, students and their parents have to be informed about the way the educational system works. Such knowledge, however, tends to vary across social groups. This study investigates the differences in education‐related knowledge between native and migrant mothers in the German context. Empirical analyses based on a sample of native German mothers and mothers from Turkey or the former Soviet Union (N = 2076) indicate that migrant mothers know less about the German educational system than their native counterparts. An investigation of the potential sources of these knowledge gaps shows that migrants’ weaker socio‐economic status explains a substantial part of their lower level of knowledge, particularly among families of Turkish origin. Furthermore, migrants’ less profitable social network composition and lower levels of German language skills contribute to their information deficits. Based on these empirical results, the study considers opportunities for improving the knowledge base of migrant parents.     

Configurations of Adolescents' Peer Experiences: Associations With Parent–Child Relationship Quality and Parental Problem Behavior

Adolescents' peer experiences embrace behavior, relationship quality, status, and victimization, but studies that account for multiple dimensions are rare. Using latent profile modeling and measures of peer behavior, relationship quality, peer status, and victimization assessed from 1,677 adolescents, four profiles were identified: High Quality, Low Quality, Low Quality Victimized, and Deviant Peers. Multinomial logistic regressions showed that negative parent–child relationships in preadolescence reduced the likelihood of High Quality peer relations in mid‐adolescence but only partly differentiated between the other three profiles. Moderation by gender was partly found with girls showing greater sensitivity to parent–child relationship quality with respect to peer experiences. Results underline the multifaceted nature of peer experiences, and practical and theoretical implications are discussed.     

Should We Stay or Should We Go? Local and National Factionalism in the National Organization for Women

While the National Organization for Women (NOW) has endured over time, it has faced significant internal factionalism. In this article, I ask why some of these factions resulted in schisms, while other factions persisted in NOW over time. This is a critical question for understanding how organizational location and factional collective identities combine to produce different outcomes when internal conflict breaks out. My analysis of interview, archival, and secondary data indicates that organizational location influences factions’ independent collective identities, shaping what they want and their perceptions of opportunities to change their organization. Compared to national level factions, local factions also lack the ability to use NOW’s hierarchical structure to their advantage in their effort to stay. This sheds lights on the distinct patterns of factionalism and schism in formalized groups.

Performance Evaluation of Foreign Subsidiaries: A Review of the Literature and a Contingency Framework

During recent years, the literature on the international dimension of business has grown. In particular, the literature on headquarters–subsidiary relationships has expanded. This paper aims to review the literature on performance evaluation and elaborate an integrative contingency framework. This contingency framework helps to clarify the concept of performance evaluation and to classify existing contributions. Furthermore, the framework serves as a tool to identify potential influencing factors on performance evaluation at corporate and at subsidiary level. By reviewing existing studies, the paper analyses the impact of these influencing factors on performance evaluation and reveals mostly contradictory results or no significant impact at all. Based on the findings, more research outside the classical tradition of contingency approaches is suggested.     

Intellectual property in music: A historical analysis of rhetoric and institutional practices ∗

In this paper we look at the educational assumptions that underlie the notion of learning from experience and at the specific circumstance of teaching (participatory) action research in the context of higher education. We take the view that ‘learning from experience’ is not merely a psychological mechanism, but a process of socialisation of its own kind.

By first looking at the ‘basic understandings’ of social situations and learning cultures we draw our attention to a reassessment of the significance of trivia. Accordingly, reflection on action has to pay attention to the small things in the social situation reflected upon. In addition, we use the findings from an earlier research done into what people consider as ‘real' learning and juxtapose them to the hidden curriculum of learning situations in institutional settings such as universities.

We conclude our paper by pointing to the differentiation between learning about, in and for practice.     

A School Feeding Supply Chain Framework: Critical Factors for Sustainable Program Design

School feeding is an established development aid intervention with multiple objectives including education, nutrition, and value transfer. Traditionally run by international organizations in low‐income settings, school feeding programs have had a substantial impact in many less‐developed countries. However, recent rethinking by the World Bank and the World Food Programme has prompted a shift toward long‐term, sustainable solutions that rely more upon local resources, local capacity, and community participation. Supply chain management, which is critical to program delivery, is vital to developing a sustainable approach to school feeding. We propose a theoretical framework that identifies the internal and external factors that shape the supply chain and connects them to the objectives and performance measures of sustainable programs. Drawing upon supply chain management theory, current school feeding practices, and expert feedback, this article contributes to development aid logistics and program transitioning with a focus on sustainable program design. It aims to provide a comprehensive introduction to school feeding and relevant supply chain issues, a framework to identify sustainability problems in school feeding supply chains, and a starting point for further research on program design.
