Voluntas Symposium: Comments on Salamon and Sokolowski’s Re-conceptualization of the Third Sector

With their “Beyond Nonprofits: Re-conceptualizing the Third Sector”, Salamon and Sokolowski have made an important contribution to the ongoing debate on how to define the third sector. This Voluntas symposium brings together the comments of five leading scholars both supportive and critical of the new definition. The comments are based on a debate held at the conference of the International Society for Third Sector Research, in Stockholm in 2016.     

Fundamentals for an International Typology of Social Enterprise Models

The quest for a widely accepted definition of social enterprise (SE) has been a central issue in the last two decades. However, it only seems feasible today to identify a few criteria that were most debated: the specific role of individual social entrepreneurs, the place of social innovation, the search for market income and the issue of governance. The arena of conceptualization efforts should now be fed with more contributions starting from bottom-up approaches built upon a hypothesis that could be termed “the impossibility of a unified definition”. In this paper, we develop a theoretical framework combining principles of interest (mutual, general and capital interest) and resource mixes to identify institutional trajectories generating four major SE models. We then show that all four SE models may address the actual diversity of SE’s social missions. Finally, we suggest that such social missions may be enhanced differently depending on the respective governance mechanisms.     

Nest design in a changing world: Great tit <Emphasis Type="Italic">Parus major</Emphasis> nests from a Mediterranean city environment as a case study

Investigations of urbanization effects on birds have focused mainly on breeding traits expressed after the nest-building stage (e.g. first-egg date, clutch size, breeding success, and offspring characteristics). Urban studies largely ignored how and why the aspects of nest building might be associated with the degree of urbanization. As urban environments are expected to present novel environmental changes relative to rural environments, it is important to evaluate how nest-building behavior is impacted by vegetation modifications associated with urbanization. To examine nest design in a Mediterranean city environment, we allowed urban great tits (Parus major) to breed in nest boxes in areas that differed in local vegetation cover. We found that different measures of nest size or mass were not associated with vegetation cover. In particular, nests located adjacent to streets with lower vegetation cover were not smaller or lighter than nests in parks with higher vegetation cover. Nests adjacent to streets contained more pine needles than nests in parks. In addition, in nests adjacent to streets, nests from boxes attached to pine trees contained more pine needles than nests from boxes attached to other trees. We suggest that urban-related alterations in vegetation cover do not directly impose physical limits on nest size in species that are opportunistic in the selection of nesting material. However, nest composition as reflected in the use of pine needles was clearly affected by habitat type and the planted tree species present, which implies that rapid habitat change impacts nest composition. We do not exclude that urbanization might impact other aspects of nest building behaviour not covered in our study (e.g. costs of searching for nest material), and that the strengths of the associations between urbanization and nest structures might differ among study populations or species.     

Views on inter-enterprise relationships

The paper gives an overview of major scientific approaches to inter-enterprise relationships. A distinction is made between approaches that focus on business process integration (Supply Chain Management, Costing approaches), approaches that focus on organizational collaboration (Transaction Cost Theory, Agency Theory), and approaches that focus on the business environment (Strategic Management, Network Theory, Resource Dependency Theory). Although these approaches are different with regard to their perspectives on collaboration, variables and methods, the paper shows that they are complementary tools in the analysis and design of inter-enterprise relationships.     

On the generalization and decomposition of the Bonferroni index

A simple algorithm is proposed which defines the Bonferroni as the product of a row vector of individual population shares, a linear mathematical operator called the Bonferroni matrix and a column vector of income shares. This algorithm greatly simplifies the decomposition of the Bonferroni index by income sources or classes and population subgroups. The proposed algorithm links also the Bonferroni index to the concepts of relative deprivation and social welfare and leads to a generalization where the traditional Bonferroni and Gini indices are special cases. The paper ends with an empirical illustration based on EU-SILC data for the year 2008.
