From Cowboys to Diplomats: Challenges for Social Entrepreneurship in The Netherlands

Social entrepreneurship—a new business model that combines a social goal with a business mentality—is in a transitional phase, from a rough cowboy market to a more established market niche. This process results in two interconnected dilemmas for the social entrepreneur. First, how it can capture market share despite its role as an antagonist to current market values. Second, how it can prevent the loss of its own core values in the course of greater interaction with the incumbent regimes. Using a tool known from innovation sciences to analyse radical innovations, namely strategic niche management, and both survey data and interviews from actors in the Netherlands, this article shows that social entrepreneurs have an attitude that is still more in line with the cowboy market than with the new diplomatic role they are expected to take on. Subsequently, it provides recommendations on how to achieve this new attitude.     

Sustainable development in historic areas: Adaptive re-use challenges in traditional houses in Sanliurfa,Turkey

The adaptive re-use of buildings is an approach for developing historical areas, and it extends the life of historical patterns. However, adaptive re-use is applied to development projects in different ways including compatible re-use and most appropriate re-use, both of which contribute to the sustainability of historic areas. The present study discusses the challenges associated with the compatible re-use and most appropriate re-use approaches for commercial and community development. In the case of commercial development, re-use is generally initiated by private entrepreneurship and is typically a new activity intended to generate income to sufficiently cover restoration and maintenance costs. Examples include the re-using as restaurants and hotels. Community re-use, which is mostly initiated by governmental involvement or development trusts, does not generate sufficient income to cover restoration and maintenance costs, but it does provide social benefits to the community. The present study demonstrates that design criteria can emphasise the significance of cultural heritage through adaptive-reuse. The research methodology used is tested through six selected case studies analysing sustainable development activities involving the traditional houses of Sanliurfa in Turkey. The aim of analysing the changes and their effects on the traditional houses of Sanliurfa and their historical environment is to highlight the challenges and approaches to re-use in terms of development involving historical patterns and conservation areas to provide guidelines for future projects.     

International Strategy and Knowledge Creation: The Advantage of Foreignness and Liability of Concentration

International business scholars increasingly emphasize regional strategies based on an optimal location of downstream sales. There has been less scholarly attention, however, to the relationship between international strategy and upstream knowledge creation including R&D. Building on contemporary strategic management theory and the knowledge‐based view we remedy this. The viability of home‐regional or bi‐regional strategies is based on common assumptions that imply negative consequences of distance and foreignness for downstream sales and marketing and benefits from agglomeration for upstream knowledge creation activities including R&D. In contrast, we propose that upstream knowledge creation, radical innovation in particular, rather gains from distance and foreignness and from being dispersed, suggesting the effectiveness of a global strategy. Based on the resource‐based view and recent research on the economics of strategic opportunities and competitive advantage, we provide theoretical explanations for this. We demonstrate how a global multinational corporation is uniquely equipped with knowledge extensity including heterogeneous social‐identity frames in multiple sub‐units. Thanks to arbitrage advantages between the sub‐units’ separate and often locally embedded knowledge, a global multinational corporation can address complex interdependences and interactions between knowledge sets required for knowledge creation. This suggests that maximum exploration capabilities are made possible by a global rather than a home‐regional or bi‐regional strategy.     

Plug-in estimators for the mean value and variance functions in delayed renewal processes

Abstract

In this paper, we deal with the problem of estimating the delayed renewal and variance functions in delayed renewal processes. Two parametric plug-in estimators for these functions are proposed and their unbiasedness, asymptotic unbiasedness and consistency properties are investigated. The asymptotic normality of these estimators are established. Further, a method for the computation of the estimators is given. Finally, the performances of the estimators are evaluated for small sample sizes by a simulation study.     

Quantile and mean value measures of search process complexity

Performance measures of metaheuristic algorithms assess the quality of a search process by statistically analysing its performance. Such criteria serve two purposes: they provide the verdict on which algorithm is better for what task, and they help applying an algorithm on a given task in the most effective way. The latter goal may be achieved by an appropriate restart strategy of the search process. Furthermore, these criteria are traditionally based on analysis of the search step mean value. Our aim is to elaborate the mean value analysis as well, but via a novel and more general quantile-based analytic approach, which can be used to define new measures. We prove and demonstrate this purpose on three quantile-based performance measures.     

Common knowledge and limit knowledge

We study the relationship between common knowledge and the sequence of iterated mutual knowledge from a topological point of view. It is shown that common knowledge is not equivalent to the limit of the sequence of iterated mutual knowledge. On that account the new epistemic operator limit knowledge is introduced and analyzed in the context of games. Indeed, an example is constructed where the behavioral implications of limit knowledge of rationality strictly refine those of common knowledge of rationality. More generally, it is then shown that limit knowledge of rationality is capable of characterizing any solution concept for some appropriate epistemic-topological conditions. Finally, some perspectives of a topologically enriched epistemic framework for games are discussed.     

Identification and Inference With Many Invalid Instruments

We study estimation and inference in settings where the interest is in the effect of a potentially endogenous regressor on some outcome. To address the endogeneity, we exploit the presence of additional variables. Like conventional instrumental variables, these variables are correlated with the endogenous regressor. However, unlike conventional instrumental variables, they also have direct effects on the outcome, and thus are “invalid” instruments. Our novel identifying assumption is that the direct effects of these invalid instruments are uncorrelated with the effects of the instruments on the endogenous regressor. We show that in this case the limited-information-maximum-likelihood (liml) estimator is no longer consistent, but that a modification of the bias-corrected two-stage-least-square (tsls) estimator is consistent. We also show that conventional tests for over-identifying restrictions, adapted to the many instruments setting, can be used to test for the presence of these direct effects. We recommend that empirical researchers carry out such tests and compare estimates based on liml and the modified version of bias-corrected tsls. We illustrate in the context of two applications that such practice can be illuminating, and that our novel identifying assumption has substantive empirical content.     

Cross-National Measurement Invariance of the Teacher and Classmate Support Scale

The cross-national measurement invariance of the teacher and classmate support scale was assessed in a study of 23202 Grade 8 and 10 students from Austria, Canada, England, Lithuania, Norway, Poland, and Slovenia, participating in the Health Behaviour in School-aged Children (HBSC) 2001/2002 study. A multi-group means and covariance analysis supported configural and metric invariance across countries, but not full scalar equivalence. The composite reliability was adequate and highly consistent across countries. In all seven countries, teacher support showed stronger associations with school satisfaction than did classmate support, with the results being highly consistent across countries. The results indicate that the teacher and classmate support scale may be used in cross-cultural studies that focus on relationships between teacher and classmate support and other constructs. However, the lack of scalar equivalence indicates that direct comparison of the levels support across countries might not be warranted.     

The demographics of same-sex marriages in Norway and Sweden

The present study investigates the demographics of same-sex marriages--that is, registered partnerships-in Norway and Sweden. We give an overview of the demographic characteristics of the spouses of these partnerships, study patterns of their divorce risks, and compare the dynamics of same-sex couples with those of heterosexual marriages. We use longitudinal information from the population registers of the two countries that cover all persons in partnerships. Our demographic analyses include information on characteristics such as age, sex, geographic background, experience of previous opposite-sex marriage, parenthood, and educational attainment of the partners involved. The results show that in many respects, the distributions of married populations on these characteristics differ by the sex composition of the couples. Patterns in divorce risks are rather similar in same-sex and opposite-sex marriages, but divorce-risk levels are considerably higher in same-sex marriages. The divorce riskforfemale partnerships is double that for male partnerships.     

Adaptation and Validation of the Life Events and Difficulties Schedule for Use With High School Dropouts

The Life Events and Difficulties Schedule (LEDS) is considered the standard for measuring psychosocial stressor exposure, but it has not been used with academically at‐risk adolescents, including high school dropouts. The goal of this study was to (1) adapt the LEDS for use with this population, and (2) examine the reliability (interrater) and validity (concurrent and predictive) of this adaptation among a sample of vulnerable adolescents (N = 545). Good reliability coefficients (.79–.90) were obtained, and stressor exposure was associated with concurrent criteria indexing mental health outcomes (depression) and major risk factors for dropout (administratively recorded and self‐reported). Also, LEDS scores predicted dropout beyond these risk factors. The adapted LEDS appears useful for describing academically struggling adolescents’ stressor exposure.
