Hybridization of institutions

Extended version including all proofsModal logics are successfully used as specification logics for reactive systems. However, they are not expressive enough to refer to individual states and reason about the local behaviour of such systems. This limitation is overcome in hybrid logics which introduce special symbols for naming states in models. Actually, hybrid logics have recently regained interest, resulting in a number of new results and techniques as well as applications to software specification. In this context, the first contribution of this paper is an attempt to ‘universalize’ the hybridization idea. Following the lines of [DS07], where a method to modalize arbitrary institutions is presented, the paper introduces a method to hybridize logics at the same institution-independent level. The method extends arbitrary institutions with Kripke semantics (for multi-modalities with arbitrary arities) and hybrid features. This paves the ground for a general result: any encoding (expressed as comorphism) from an arbitrary institution to first order logic (FOL) deter- mines a comorphism from its hybridization to FOL. This second contribution opens the possibility of effective tool support to specification languages based upon logics with hybrid features.Fundação para a Ciência e a Tecnologia (FCT

Globalization, Africa and the Question of Imperialism

The influence of globalization has been a growing concern for social scientists and cultural theorists. For many, global media institutions abet cultural globalization, which is synonymous with cultural homogenization, which refers the processes of global uniformity and standardization of human cultural experience. Drawing from the perspective of globalization, critical discourse analysis and cultural studies, this paper presents an argumentative discussion on globalization and its cultural influence in Africa. It examined how globalization has been associated with a range of cultural consequences. These can be analyzed in terms of three major theses; namely homogenization, polarization and hybridization. In addition, this paper reviews the cultural imperialism argument in terms of how global media institutions negatively affect the culture of Africans

Entrepreneurial workaround practices in severe institutional voids: Evidence from Kenya

Entrepreneurs in developing economies try to cope with weak or absent formal institutions – often referred to as ‘institutional voids’ – by relying extensively on intermediary organizations such as business incubators and development organizations or informal institutions such as political, kinship, or family relationships. However, in many African countries, intermediary support is limited and informal institutions are also unreliable, adding risks and costs to doing business and increasing the severity of institutional voids in the surrounding ecosystem. We investigate the practices followed by 47 commercial entrepreneurs in Kenya to ‘work around’ these severe institutional voids to achieve their goals of business creation and growth. We find that severe institutional voids stimulate the hybridization of goals to include social value creation, create a need for a more strategic orchestration of business relationships, and motivate entrepreneurs to proactively cross-brace the institutional infrastructure around them. We contribute by unveiling the important role of entrepreneurs as microinstitutional agents in developing economies and by detailing how commercial and social goals become intertwined in the context of African entrepreneurship

Which market protocols facilitate fair trading?

We study the performance of four market protocols with regard to their ability to equitably distribute the gains from trade among two groups of participants in an exchange economy. We test the protocols by running (computerized) experiments. Assuming Walrasian tatonemment as benchmark, there is a clear-cut ranking from best to worst: batch auction, nondiscretionary dealership, the hybridization of a dealership and a continuous double auction, and finally the pure continuous double auction.allocative efficiency, allocative fairness, allocative neutrality, comparison of market institutions, market microstructure, performance criteria.

How institutions affect retailers' internationalization ?

This paper examines the institutional and economic factors determining success and failure of global retailers abroad through the trajectories of Wal-Mart and Carrefour. Three kinds of explanations are considered : the time and modalities of entry and development, the factors that allow the exercise of an upstream market power and the sensitivity to labor standards. The two retailers are note identically affected by those factors. It suggests that the process of hybridization between different varieties of capitalism and productive models shapes in a crucial way the international trajectories of retailers.retail – internationalization – performance - institutions

Legitimizing Indigenous Knowledge in Zimbabwe: A Theoretical Analysis of Postcolonial School Knowledge and Its Colonial Legacy

This article is a theoretical discussion on the social construction of knowledge in colonial and postcolonial Zimbabwe. It examines effects of hegemonic knowledge constructions and how they may be delegitimated through incorporating indigenous knowledge in postcolonial school curricular. The article questions the importance attached to Eurocentric school knowledge and the devaluation of indigenous knowledge in postcolonial states. It further argues that indigenous knowledge as informal knowledge plays a major role in society and should be formalized in educational institutions to constitute a transformative and inclusive educational system. The article proposes hybridization of knowledge to give voice to the formerly marginalized in school curricular in Zimbabwe. It also proposes that knowledge as a historical, cultural, social, spiritual and ideological creation should be a product of collaborated efforts from all possible stakeholders to foster social development and self-confidence in individuals

Conversion as a Mechanism of Hybridization: The Institutional Transfer of Industrial Relations and Vocational Training from Western to Eastern Germany

Looking back over the two decades since German unification, the main questions I want to answer are to what extent and through what mechanisms the transfer of the system of industrial relations and vocational training - two cornerstones of the West German model - has occurred in eastern Germany. The literature argues that institutional transfer very often leads to a process of hybridization in institutions. However, the concept of hybridization has also been criticized as being mainly descriptive and vague about the actual mechanisms of hybridization. In this paper I argue that these mechanisms should be specified further and suggest that the hybridization approach can be fruitfully linked to recent theories of institutional change. As far as the transfer of industrial relations and vocational training from western to eastern Germany is concerned, I argue in particular that hybridization has mainly occurred through what institutional literature has recently defined as the mechanism of conversion

The Diffusion of Regulatory Oversight

The idea of cost-benefit analysis has been spreading internationally for centuries — at least since an American named Benjamin Franklin wrote a letter in 1772 to his British friend, Joseph Priestley, recommending that Priestley weigh the pros and cons of a difficult decision in what Franklin dubbed a “moral or prudential algebra” (Franklin 1772) (more on this letter below). Several recent studies show that the use of benefit-cost analysis (BCA), for both public projects and public regulation of private activities, is now unfolding in countries on every habitable continent around the world (Livermore and Revesz 2013; Quah and Toh 2012; De Francesco 2012; Livermore 2011; Cordova-Novion and Jacobzone 2011). This global diffusion of BCA is intermingled with the global diffusion of regulatory capitalism, in which privatized market actors are supervised by expert regulatory agencies (Levi-Faur 2005; Simmons et al. 2008), and with the international spread of ex ante regulatory precautions to anticipate and prevent risks despite uncertainty (Wiener et al. 2011)
