On Measures and Measurements: a Fibre Bundle approach to Contextuality

Contextuality is the failure of "local" probabilistic models to become global ones. In this paper we introduce the notions of \emph{measurable fibre bundles}, \emph{probability fibre bundles}, and \emph{sample fibre bundle} which capture and make precise the former statement. The central notions of contextuality are discussed under this formalism, examples worked out, and some new aspects pointed out.Comment: 14 pages; no figures; Purdue-Winer Memorial Lectures 2018; submitted to Phil.

Impact of strategy, HRM Strength and HRM bundles on innovation performance and organizational performance

This study uses structural equation modeling to test a model of the impact of human resource management bundles on perceived organizational performance and innovation performance, on a large sample of companies. Strategic management orientation and innovation as a strategic factor are proposed to influence the existence of two types of HR bundles, functional flexibility and performance management, as well as contributing to stronger HR systems. HRM Strength, which integrates the metafeatures of an HRM system and provides a common interpretation of organizational goals, has a strong positive impact on both innovation and organizational performances. Finally, while both the functional flexibility and performance management bundles have a positive impact on organizational performance, they do not seem to affect innovation performance.

Writing new scripts: redefining managerial agency in Cuba

Transitional societies are faced with particularly challenging and pressing problems. These usually involve the passage from a centralised, socialist-based society, to a decentralised, market-based economy. This paper addresses a somewhat different case: that of Cuba. According to the official discourse, the island is not in a state of transition. On the contrary, it is assumed that the conquests of the revolution are there to stay. Nonetheless, significant changes are taking place. The market logic is being adopted in a growing number of cases, ranging from empresas mixtas to the weak signals of entrepreneurial activity. Drawing on a series of eight focus groups with a total of 106 Cuban executives and management scholars, this paper addresses the uniqueness of the Cuban case on the basis of the theory of structuration. The paper reports how the need to keep the faith is being added with the adoption of Western management practices, and how the interplay between planned and emergent change is sculpting transition through the redefinition of managerial scripts.Cuba, managerial scripts, agency, structuration theory, focus groups

The dynamics of managerial ideology: analyzing the cuban case

After the collapse of state socialism in Eastern Europe, management researchers devoted considerable energy to investigate ways to smooth transition to market economies. But one country of the former Soviet bloc, Cuba resisted transition and reaffirmed loyalty to communism. Little is known about management in Cuba on the managerial impacts of the combination of two major environmental forces: the American embargo and the Soviet Union collapse, both of which have challenged the sustainability of the communist regime. This study intends to approach one particular aspect of management in Cuba: the relationship between national ideology and management practice. To analyze these topics, direct qualitative data from focus groups with Cuban managers and management professors was obtained and complemented with documentary analysis. Results suggest that the dynamics of managerial ideology can be understood as the interplay of several processes operating at distinct levels: institutional, professional, organizational and individual. The study provides a nested, multi-level understanding of management and organization as parts of a wider institutional context, which is both a source of constraint and a non-tangible resource to be used by ideological bricoleurs. The interplay between the acceptance of ideology and its use as a practical resource is a potential source of change. As such, the same professional class (managers) may be both a source of continuity and a trigger of change - a finding that is line with institutional theorys claim that it is necessary to understand both institutionalization and de-institutionalization for understanding organizational change and continuity.Cuba, managerial ideology, institutional change, ideological bricolage
