Consolidation of Belief in Two Logics of Evidence

Recently, several logics have emerged with the goal of modelling evidence in a more relaxed sense than that of justifications. Here, we explore two of these logics, one based on neighborhood models and the other being a four-valued modal logic. We establish grounds for comparing these logics, finding, for any model, a counterpart in the other logic which represents roughly the same evidential situation. Then we propose operations for consolidation, answering our central question: What should the doxastic state of a rational agent be in a given evidential situation? These operations map evidence models to Kripke models. We then compare the consolidations in the two logics, finding conditions under which they are isomorphic. By taking this dynamic perspective on belief formation we pave the way for, among other things, a study of the complexity, and an AGM-style analysis of rationality of these belief-forming processes

Evidence-Based Beliefs in Many-Valued Modal Logics

Rational agents, humans or otherwise, build their beliefs from evidence – a process which we call consolidation. But how should this process be carried out? In this thesis, we study a multi-agent logic of evidence and the question how agents should form beliefs in this logic. The main contributions of this thesis are twofold. First, we present and study a many-valued modal logic, and show how it can be suitable for modelling multi-agent scenarios where each agent has access to some evidence, which in turn can be processed into beliefs. This is a technical and practical contribution to many-valued modal logics. Second, we open new paths for research in the field of evidence logics: we show a new approach based on many-valued logics, we highlight the concept of consolidations and the importance of looking at their dynamic nature, and build a methodology based on rationality postulates to evaluate them

Iterative social consolidations:Forming beliefs from many-valued evidence and peers' opinions

Recently, several logics modelling evidence have been proposed in the literature. These logics often also feature beliefs. We call the process or function that maps evidence to beliefs consolidation. In this paper, we use a four-valued modal logic of evidence as a basis. In the models for this logic, agents are represented by nodes, peer connections by edges and the private evidence that each agent has by a four-valued valuation. From this basis, we propose methods of consolidating the beliefs of the agents, taking into account both their private evidence as well as their peers' opinions. To this end, beliefs are computed iteratively. The final consolidated beliefs are the ones in the point of stabilization of the model. However, it turns out that some consolidation policies will not stabilize for certain models. Finding the conditions for stabilization is one of the main problems studied here, along with other properties of such consolidations. Our main contributions are twofold: we offer a new dynamic perspective on the process of forming evidence-based beliefs, in the context of evidence logics, and we set up and address some mathematically challenging problems, which are related to graph theory and practical subject areas such as belief/opinion diffusion and contagion in multi-agent networks.</p

Continuous Improvement Through Knowledge-Guided Analysis in Experience Feedback

Continuous improvement in industrial processes is increasingly a key element of competitiveness for industrial systems. The management of experience feedback in this framework is designed to build, analyze and facilitate the knowledge sharing among problem solving practitioners of an organization in order to improve processes and products achievement. During Problem Solving Processes, the intellectual investment of experts is often considerable and the opportunities for expert knowledge exploitation are numerous: decision making, problem solving under uncertainty, and expert configuration. In this paper, our contribution relates to the structuring of a cognitive experience feedback framework, which allows a flexible exploitation of expert knowledge during Problem Solving Processes and a reuse such collected experience. To that purpose, the proposed approach uses the general principles of root cause analysis for identifying the root causes of problems or events, the conceptual graphs formalism for the semantic conceptualization of the domain vocabulary and the Transferable Belief Model for the fusion of information from different sources. The underlying formal reasoning mechanisms (logic-based semantics) in conceptual graphs enable intelligent information retrieval for the effective exploitation of lessons learned from past projects. An example will illustrate the application of the proposed approach of experience feedback processes formalization in the transport industry sector

Predatory Value: Economies of Dispossession and Disturbed Relationalities

This essay introduces and theorizes the central concerns of this special issue, “Economies of Dispossession: Indigeneity, Race, Capitalism.” Financialization, debt, and the accelerated concentration of wealth today work through social relations already configured and disposed by imperial conquest and racial capitalism. In the Americas broadly and the United States specifically, colonization and transatlantic slavery set in motion the dynamics and differential racialized valuations that continue to underwrite particular forms of subjection, property, commerce, and territoriality. The conception of economies of dispossession introduced in this essay draws attention to the overriding importance of rationalities of abstraction and commensurability for racial capitalism. The essay problematizes the ways in which dispossession is conventionally treated as a self-evident and circumscribed practice of unjust taking and subtractive action. Instead, working across the lethal confluences of imperial conquest and racial capitalist predation, this essay critically situates the logic of propriation that organizes and underwrites predatory value in the historical present. Against the commensurabilities and rationalities of debt and finance capitalism, conditioned through the proprietary logics of settler colonialism and racial capitalism, the essay gestures toward alternative frameworks for building collective capacities for what the authors describe as a grounded relationality

Reducing Uncertainty in Scholarly Publishing: Concepts in the Field of Organization Studies, 1960–2008

In this paper, we investigate the dynamics in the field of organization studies. We focus on the market for scholarly publishing and trace how many and which kinds of concepts have been developed and diffused in publications over the last 48 years. We argue that scholars in the publishing market must deal with two kinds of uncertainty: uncertainty on the delicate balance of maintaining research that is both novel and attentive to existing schools of thought, and uncertainty related to the heterogeneity of institutional logics that guide research in the field. We propose that concepts are a means of uncertainty reduction for two reasons. First, working with concepts allows considering both novelty and continuity. Second, working with concepts in a way that follows the dominant field logic helps to reduce uncertainty about what is valued as publishable in the field. We find that the number of concept articles in organization studies has increased, particularly concept articles that align with the dominant logic of positivism

Policies and People: A Review of Neoliberalism and Educational Technologies in P-12 Education Research

Accountability regimes, value added, vouchers—it is difficult to ignore the evidence of market-based rationalities in global discourses around education. Such rationalities rely heavily on Information and Communications Technologies (ICTs) for their propagation and maintenance under the guise of educational technologies, or ed-tech. The purpose of this literature review is to examine educational research focused on the role ICTs have played in the neoliberalization of education across the globe. The author contends that future inquiry needs to substantiate the broad claims about the pernicious effects of neoliberalized educational technologies by engaging more directly with those most affected: teachers and students

Event Attention, Environmental Sensemaking, and Change in Institutional Logics: An Inductive Analysis of the Effects of Public Attention to Clinton's Health Care Reform Initiative.

We explore attention to Clinton's health care reform proposal, ongoing debates, and its political demise to develop theory that explains how events create opportunities for cognitive realignment and transformation in institutional logics. Our case analysis illustrates how a bottom-up process of environmental sensemaking led to the emergence and adoption of a logic of managed care, which provided new organizing principles in the hospitals' organizational field. In addition to theorization, highlighted by prior research, we propose a second mechanism of environmental sensemaking: representation of change through exemplars and environmental features. The interplay between theorization, representation, and ongoing event attention can lead to change in institutional logics over an event's life course. We found that the managed care logic did not emerge in a fully formed fashion, but that actors theorized individual dimensions of the logic consistent with changing representations of hospitals' relationships with other actors in the field. As the event unfolded, the individual dimensions came to be theorized as part of an overall managed care logic. The label “managed care,” previously understood as a specific organizational form, took on a new meaning to symbolize the organizing principles for hospitals' relationships with a variety of institutional actors as alternative models not congruent with the changing organizational field were abandoned

Organizational professionalism in globalizing law firms.

Are the challenges of globalization, technology and competition exercising a dramatic impact on professional practice whilst, in the process, compromising traditional notions of professionalism, autonomy and discretion? This paper engages with these debates and uses original, qualitative empirical data to highlight the vast areas of continuity that exist even the largest globalizing law firms. Whilst it is undoubted that growth in the size of firms and their globalization bring new challenges, these are resolved in ways that are sensitive to professional values and interests. In particular, a commitment to professional autonomy and discretion still characterises the way in which these firms operate and organize themselves. This situation is explained in terms of the development of an organizational model of professionalism, whereby the large organization is increasingly emerging as a primary locus of professionalization and whereby professional priorities and objectives are increasingly supported by organizational logics, systems and initiatives
