The evolution of intellectual property strategy in innovation ecosystems: Uncovering complementary and substitute appropriability regimes

In this article, we attempt to extend and nuance the debate on intellectual property (IP) strategy, appropriation, and open innovation in dynamic and systemic innovation contexts. We present the case of four generations of mobile telecommunications systems (covering the period 1980–2015), and describe and analyze the co-evolution of strategic IP management and innovation ecosystems. Throughout this development, technologies and technological relationships were governed with different and shifting degrees of formality. Simultaneously, firms differentiated technology accessibility across actors and technologies to benefit from openness and appropriation of innovation. Our analysis shows that the discussion of competitiveness and appropriability needs to be expanded from the focal appropriability regime and complementary assets to the larger context of the innovation ecosystem and its cooperative and competitive actor relations, with dispersed complementary and substitute assets and technologies. Consequently, the shaping of complementary and substitute appropriability regimes is central when strategizing in dynamic and systemic innovation contexts. This holds important implications for the management of open innovation, innovation ecosystems, platforms, and coopetition.     

Growing Disability Rates — the Gender Issue: The Dutch Case in an International Perspective

In the Netherlands, with its remarkably high disability rates, a new phenomenon seems to be emerging. Growing disability rates in the past few years have been exclusively caused by the growing inflow of women into the disability schemes. Comparing the Dutch situation internationally shows that roughly the same problem seems to exist in those countries in which there is a more general problem of large inflow into disability. Women are overrepresented in these arrangements. The Dutch literature shows that there are many factors (both work- and non-work-related) that contribute to a larger push of women towards disability. We conclude that the benefit system can be seen as a sort of "filter". If the filter is weak, many persons will enter disability. If the pressure on women to enter is larger (or the forces to stop women from entering disability smaller), then inflow risks for women will be higher.     

It takes two to tango: the integration of people with disabilities into society

The concept of integration is not well defined. It not known how people with disabilities experience integration. In this study qualitative methods were used. The aim of the article is to define a model of successful integration based on the perspectives of people with disabilities and people within their social environment. Integration consists of five elements: functioning ordinarily without receiving special attention, mixing with others that are not disabled, taking part in society, trying to realize one’s potential and directing one’s own life. Integration is obtained through a process of interaction between a person with a disability and society. This process is influenced by personal, societal and support factors. The individual with a disability and society have a mutual responsibility with respect to integration.     

A SPATIAL PERSPECTIVE ON EUROPEAN INTEGRATION: HETEROGENEOUS WELFARE AND MIGRATION EFFECTS FROM THE SINGLE MARKET AND THE BREXIT

We use a quantitative model to study the implications of European integration for welfare and net migration flows across 1,280 European regions. The model suggests that an increase of trade barriers to the level of 1957 reduces welfare by about 5%–8% on average, depending on the presumed trade elasticity. However, remote regions may face initial welfare losses of up to 10%. These heterogeneous welfare effects cause estimated net migration of 1.9% of the population to the European geographic center implying that the dismantling of trade barriers in Europe has led to a more homogeneous spatial distribution of economic activity. With regard to the Brexit, we find moderate welfare losses for the United Kingdom of 1.05% in the most pessimistic scenario while continental Europe's welfare declines by 0.41%.

Cognitively automated assembly processes: a simulation based evaluation of performance

The numerical control of an experimental assembly cell with two robots--termed a cognitive control unit (CCU)--is able to simulate human information processing at a rule-based level of cognitive control. To enable the CCU to work on a large range of assembly tasks expected of a human operator, the cognitive architecture SOAR is used. The CCU can plan assembly processes autonomously and react to ad-hoc changes in assembly sequences effectively. Extensive simulation studies have shown that cognitive automation based on SOAR is especially suitable for random parts supply, which reduces planning effort in logistics. Conversely, a disproportional increase in processing time was observed for deterministic parts supply, especially for assemblies containing large numbers of identical parts. In this contribution, the effect of phase-shifts in deterministic part supply is investigated for assemblies containing maximal different parts. It can be shown that the concept of cognitive automation is as well suitable for these planning problems.     

Dashed Hopes,Dashed Selves? A Sociometer Perspective on Self‐esteem Change Across the Transition to Secondary School

The transition from primary to secondary school challenges children's psychological well‐being. A cross‐transitional longitudinal study (N = 306; mean age = 12.2 years) examined why some children's self‐esteem decreases across the transition whereas other children's self‐esteem does not. Children's expected social acceptance in secondary school was measured before the transition; their actually perceived social acceptance was measured after the transition. Self‐esteem and Big Five personality traits were measured both pre‐ and posttransition. Self‐esteem changed as a function of the discrepancy between children's expected and actually perceived social acceptance. Furthermore, neuroticism magnified self‐esteem decreases when children's ‘hopes were dashed'—when they experienced disappointing levels of social acceptance. These findings provide longitudinal support for sociometer theory across the critical transition to secondary school.     

Intersectional Individuality: Georg Simmel's Concept of “The Intersection of Social Circles” and the Emancipation of Women

Georg Simmel's “The intersection of social circles,” a chapter in his 1908 Sociology, contains discussions of class, religion, ethnic, and gender relations that are highly relevant to contemporary sociological concerns. Simmel's argument is based on a notion of historical dynamic that interprets increasingly complex intersectionality as a sign of progressing civilization. The article establishes how Simmel describes “the intersection of social circles” and then looks at Simmel's account through the concept of “intersectionality” as developed in contemporary feminist theory. The article suggests that although some aspects of Simmel's account of women in modernity are incompatible with contemporary feminism, the shared use of the same image, “intersection,” in Simmel and in contemporary feminist theory is the symptom of a shared concern with a particular aspect of the complexity of modern society. In Simmel, the increasing density of the intersections of social circles points to the increasingly complex individuality of modern subjects, whereas the use of the same image in contemporary feminist theory is part of a critique of inequality and oppression in the same modern society whose advent Simmel celebrated. Intersectionality is a characteristic of modern society that first became visible more than a century ago and has meanwhile become ever the more a signature of modernity.     

Investigating impacts of complex sampling on latent growth curve modelling

We investigate the impacts of complex sampling on point and standard error estimates in latent growth curve modelling of survey data. Methodological issues are illustrated with empirical evidence from the analysis of longitudinal data on life satisfaction trajectories using data from the British Household Panel Survey, a national representative survey in Great Britain. A multi-process second-order latent growth curve model with conditional linear growth is used to study variation in the two perceived life satisfaction latent factors considered. The benefits of accounting for the complex survey design are considered, including obtaining unbiased both point and standard error estimates, and therefore correctly specified confidence intervals and statistical tests. We conclude that, even for the rather elaborated longitudinal data models that were considered, estimation procedures are affected by variance-inflating impacts of complex sampling.     

Sind Lehrerinnen für den geringeren Schulerfolg von Jungen verantwortlich?

Since the beginning of the 1990s we find that girls are increasingly more successful in german schools than boys. Simultaneous to this development the share of female teachers in the school system has gradually grown. This feminisation of the teacher profession is said to have led to a feminisation of schools, resulting in girls achieving better academic results than boys. This relatively old thesis has rarely been empirically examined and the results of such attempts have been inconsistent. Drawing on data from the ELEMENT-study conducted in Berlin elementary schools between 2003 and 2005, this paper examines, whether boys' competencies in math and reading develop worse, whether they receive lower grades and whether they are less frequently recommended for the Gymnasium when there is a high share of female teachers at the school. The results show that boys do indeed receive lower grades in mathematics and are consequently recommended for the Gymnasium minimal less frequently in schools with a high share of female teachers as compared to schools with a lower share of female teachers. Girls, on the other hand, have higher reading competencies in schools with a high share of female teachers.
