We show that previous results from epistemic network models showing the benefits of decreased connectivity in epistemic networks are not robust across changes in parameter values. Our findings motivate discussion about whether and how such models can inform real-world epistemic communities. As we argue, only robust results from epistemic network models should be used to generate advice for the real-world, and, in particular, decreasing connectivity is a robustly poor recommendation.

In this paper, we examine the relationship between general relativity and the theory of Einstein algebras. We show that according to a formal criterion for theoretical equivalence recently proposed by Halvorson and Weatherall, the two are equivalent theories.

In this rigorous investigation into the logic of truth Anil Gupta and Nuel Belnap explain how the concept of truth works in both ordinary and pathological..

A classic result in the foundations of Yang-Mills theory, due to J. W. Barrett ["Holonomy and Path Structures in General Relativity and Yang-Mills Theory." Int. J. Th. Phys. 30, ], establishes that given a "generalized" holonomy map from the space of piece-wise smooth, closed curves based at some point of a manifold to a Lie group, there exists a principal bundle with that group as structure group and a principal connection on that bundle such that the holonomy map corresponds to (...) the holonomies of that connection. Barrett also provided one sense in which this "recovery theorem" yields a unique bundle, up to isomorphism. Here we show that something stronger is true: with an appropriate definition of isomorphism between generalized holonomy maps, there is an equivalence of categories between the category whose objects are generalized holonomy maps on a smooth, connected manifold and whose arrows are holonomy isomorphisms, and the category whose objects are principal connections on principal bundles over a smooth, connected manifold. This result clarifies, and somewhat improves upon, the sense of "unique recovery" in Barrett's theorems; it also makes precise a sense in which there is no loss of structure involved in moving from a principal bundle formulation of Yang-Mills theory to a holonomy, or "loop", formulation.

Reactive oxygen species (ROS) are highly reactive molecules produced in cells. So far, they have mostly been connected to diseases and pathological conditions. More recent results revealed a somewhat unexpected role of ROS in control of developmental processes. In this review, we elaborate on ROS in development, focussing on their connection to epithelial tissue morphogenesis. After briefly summarising unique characteristics of epithelial cells, we present some characteristic features of ROS species, their production and targets, with a focus on proteins important (...) for epithelial development and function. Finally, we provide examples of regulation of epithelial morphogenesis by ROS, and also of developmental genes that regulate the overall redox status. We conclude by discussing future avenues of research that will further elucidate ROS regulation in epithelial development. (shrink)

This manuscript is intended as a technical supplement to Rosenstock and O'Connor. Calculations are presented for the expected return for strategic players of an iterated prisoner's dilemma which includes guilt-prone grim trigger players, who apologize when they accidentally defect, as well as fake apologizers who in fact act as defectors. See Rosenstock and O'Connor for a discussion of how the results presented here can be interpreted, using ESS analysis and exploring basins of attraction under the replicator dynamics, to help understand (...) the conditions under which guilt can evolve. I hope for this note to both make it easier for others to understand and build on those results, and to demonstrate how expected returns can be calculated for various strategies in various games.

Economic migration is a significant and growing development around the world but has produced unequal outcomes and experiences for marginalized groups. To theoretically explain such inequalities, we argue that integration experiences of immigrants in the host country differ based on the privilege that their demographic category bestows on them (or not). We elucidate our arguments by unpacking the concept of ‘privilege’ to theorize two key sources of privilege—_locational_ and _historical_—and explain them using the global economic divide (Global North vs. Global (...) South) and local social divides (race and caste). We propose that locational and historical privilege manifest as various types of capital that immigrants carry into their host countries. We juxtapose these two sources of privilege and its levels (low vs. high) to develop a typology of immigrants—_Marginalized, Peripheral, Assimilated,_ and _Wanted—_that captures differences in migrants’ integration experiences. By shining a light on the systematic differences between immigrants based on privilege, our research brings additional nuance to the scholarship on immigrant workers and inclusive organizations; and broadens avenues to make human resource practices more ethical by taking these differences into account.

To make sense of large data sets, we often look for patterns in how data points are “shaped” in the space of possible measurement outcomes. The emerging field of topological data analysis offers a toolkit for formalizing the process of identifying such shapes. This article aims to discover why and how the resulting analysis should be understood as reflecting significant features of the systems that generated the data. I argue that a particular feature of TDA—its functoriality—is what enables TDA to (...) translate visual intuitions about structure in data into precise, computationally tractable descriptions of real-world systems.

The principle of homophily says that people associate with other groups of people who are mostly like themselves. Many online communities are structured around groups of socially similar individuals. On Twitter, however, people are exposed to multiple, diverse points of view through the public timeline. The authors captured 30,000 tweets about the shooting of George Tiller, a late-term abortion doctor, and the subsequent conversations among pro-life and pro-choice advocates. They found that replies between like-minded individuals strengthen group identity, whereas replies (...) between different-minded individuals reinforce in-group and out-group affiliation. Their results show that people are exposed to broader viewpoints than they were before but are limited in their ability to engage in meaningful discussion. They conclude with implications for different kinds of social participation on Twitter more generally. (shrink)

In this paper, I draw attention to various doctrines common to different Vedāntic traditions. In particular, I pay close attention to the doctrine of beginningless _karman_. I also note that this doctrine seems to stand in tension with Leibnizian Cosmological Arguments (LCAs) and Kalām Cosmological Arguments (KCAs). This tension arises because defenders of these arguments argue that an infinite causal regress or an actual infinite cannot be physically instantiated and because the doctrine of beginningless _karman_ seems to imply that such (...) a regress or actual infinite can be physically instantiated. I address this tension by showing that not all interpretations of beginningless _karman_ involve an infinite causal regress or an actual infinite. I close this paper by highlighting a few features that Vedāntic traditions have that make them more resistant to some objections to LCAs and KCAs. (shrink)

Using results from evolutionary game theory, we analyze the conditions under which guilt can provide individual fitness benefits to actors, and so evolve. In particular, we focus on the individual benefits of guilty apology. We find that guilty apology is more likely to evolve in cases where actors interact repeatedly over long periods of time, where the costs of apology are low or moderate, and where guilt is hard to fake.

Business ethics is understood in a comprehensive and differentiated sense, as in recent years it has evolved under the influence of globalization. The present book examines inclusive growth, which includes more than just poverty alleviation and seeks to address the problem of equity through the enhancement of opportunities for all parties. This conforms to the fundamental task of business ethics, which is to enhance the ethical quality of decision-making and actions taken at all levels of business, id est, at the (...) personal (micro-), organizational (meso-), and systemic (macro-) levels and thus extending the narrow notion of business ethics as a niche for managers with good intentions. In the real world of competition and coordination, various situations produce various tradeoffs that the three pillars of the economy - Business, Government and Society - have to pursue for their survival and sustenance. In this book, we look into many such case studies in which the strength of one component leads to a benefit for one of the other components and a detriment for the other, thus causing an imbalance between the three pillars. This book will be equally valuable to students, philosophers, decision-makers in business and policy-makers at large. (shrink)

The international community has policy tools to influence business activity within and between nations, and to help ensure that globalization proceeds in a way that benefits all. This book aims at underlining the big-picture thinking on issues related to the roles that business can play in fostering an equitable and ecologically sustainable world.

The 'wall' that differentiates two different kinds of attitudes of the same person at different points of time denotes, as the author envisages, Conscious Attitudinal Infringement Area (CAIA), where moral dilemmas take birth to bridge the two different kinds of attitudes to give way to attitudinal interrelatedness. In order to 'reinforce' CAIA to narrow the gap between personal behaviour and public behaviour, lead a moral life and behave ethically in public, there has to be harmony between the inner life of (...) thoughts, feelings and emotions, and the circumstances and events in the person's outer environment. After discussing the corporate scenario in India in brief, the author has put forward a model called Action By Objectives (ABO) as the basis of the harmonization approach. Drawing inspiration from the ethical aspects of Buddhism, Sufism, Sikhism and Vedanta in this context, he suggests an abhyasa yoga (perfection through disciplined practice) menu for refining samskaras (inner predispositions) and reaching the ultimate level of positive, inspiring leadership.

Debates about God’s personhood, or lack thereof, are central to philosophy of religion. This paper aims to advance these debates by presenting the “greatness of personhood argument” for God’s personhood and a dilemma for those who deny God’s personhood. I also consider various objections to this argument and this dilemma and argue that they fail. Notably, my reasoning in defence of personal theism is cross-cultural insofar as personal theists across various religious traditions can use it. Thus, this paper defends personal (...) theism in a manner that can bring Western and non-Western theists into closer dialogue regarding the topic of God’s personhood. (shrink)

Ruminative thinking, characterized by a recurrent focus on negative and self-related thought, is a key cognitive vulnerability marker of depression and, therefore, a key individual difference variable. This study aimed to develop a computational cognitive model of rumination focusing on the organization and retrieval of information in memory, and how these mechanisms differ in individuals prone to rumination and individuals less prone to rumination. Adaptive Control of Thought-Rational (ACT-R) was used to develop a rumination model by adding memory chunks with (...) negative valence to the declarative memory. In addition, their strength of association was increased to simulate recurrent negative focus, thereby making it harder to disengage from. The ACT-R models were validated by comparing them against two empirical datasets containing data from control and depressed participants. Our general and ruminative models were able to recreate the benchmarks of free recall while matching the behavior exhibited by the control and the depressed participants, respectively. Our study shows that it is possible to build a computational theory of rumination that can accurately simulate the differences in free recall dynamics between control and depressed individuals. Such a model could enable a more fine-tuned investigation of underlying cognitive mechanisms of depression and potentially help to improve interventions by allowing them to more specifically target key mechanisms that instigate and maintain depression.

Artificial Intelligence (AI) powered machines are increasingly mediating our work and many of our managerial, economic, and cultural interactions. While technology enhances individual capability in many ways, how do we know that the sociotechnical system as a whole, consisting of a complex web of hundreds of human–machine interactions, is exhibiting collective intelligence? Research on human–machine interactions has been conducted within different disciplinary silos, resulting in social science models that underestimate technology and vice versa. Bringing together these different perspectives and methods (...) at this juncture is critical. To truly advance our understanding of this important and quickly evolving area, we need vehicles to help research connect across disciplinary boundaries.This paper advocates for establishing an interdisciplinary research domain—Collective Human-Machine Intelligence (COHUMAIN). It outlines a research agenda for a holistic approach to designing and developing the dynamics of sociotechnical systems. In illustrating the kind of approach, we envision in this domain, we describe recent work on a sociocognitive architecture, the transactive systems model of collective intelligence, that articulates the critical processes underlying the emergence and maintenance of collective intelligence and extend it to human–AI systems. We connect this with synergistic work on a compatible cognitive architecture, instance-based learning theory and apply it to the design of AI agents that collaborate with humans. We present this work as a call to researchers working on related questions to not only engage with our proposal but also develop their own sociocognitive architectures and unlock the real potential of human–machine intelligence.

Some criticisms are offered of Barwise and Etchemendy's theory of truth, the principal one being that it violates a feature of truth called “supervenience”.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.1 (2002) 93-96 [Access article in PDF] Phenomenological Methods in Psychiatry:A Necessary First Step M. Gupta and L. Rex Kay Keywords: behavior, empathy, human science, methodology, natural science, phenomenology. WE ARE GRATEFUL to the journal for prviding the opportunity for exchange and discussion of some of the themes raised in our paper, "The impact of phenomenology on North American psychiatric assessment" and we are (...) pleased to be able to reply to the two excellent commentaries by McMillan and Morley. Both McMillan and Morley question the prospect of employing phenomenology and its methods in psychiatric assessment, and in psychiatric practice more generally. McMillan questions the utility of such a step, and Morley is pessimistic about its feasibility. We shall address each author's concerns in turn.Initially, let us restate the aims of our paper to contextualize our arguments and those made in the commentaries. First, we sought an understanding of what is meant by North American psychiatrists, working within the DSM framework, when they refer to the phenomenological approach to psychiatric assessment. To elucidate this meaning, we compared the contemporary North American usage to a small number of definitions of phenomenology, particularly those definitions that were, and are now, applied to clinical psychiatric work. Contrary to McMillan's suggestion, we did not intend to state definitively what should or should not count as phenomenological, but rather to compare North American psychiatric assessment to what typically has counted as phenomenological. Second, we sought to examine phenomenology's influence on North American psychiatric practice, particularly psychotherapy.Morley argues that such influences usually exemplify the inappropriate appending of phenomenology to psychiatric practice rather than true integration of different paradigms. Although we do not disagree with this general contention, we will argue that the deployment of phenomenological methods in psychiatric assessment is a necessary first step toward the kind of integration he proposes.McMillan makes two related but unintegrated points. First, he argues that objective, behavioral data are phenomenological, according to his broad definition of the term. Second, he proposes that, if the behavioral and the phenomenological are different, we are better off staying with the behavioral when it comes to psychiatric nosology. Let us consider these two points in succession.McMillan seeks to broaden Jasper's definition of phenomenology to include objective observations [End Page 93] as phenomenological. To this end, he distinguishes methods from aims. He summarizes Jasper's definition of phenomenology as "an empirical method for investigating 'individual psychic experience (p 55)" and claims that this is a statement of aim or objectives. He then urges us to "consider the merits of different phenomenological methodologies in terms of their success in achieving this objective" whether or not they utilize "all the methods" of phenomenology. This is much like saying that if we treat waving one's hand as a method for greeting someone, we are then free to treat the objective of the wave as one of greeting someone, and then say that anything that serves as a greeting is, by definition, a "wave." Whatever else McMillan's objective observations are, he has not convinced us that they are phenomenological, anymore than we are likely to convince you that a kiss on the lips is really just a wave.Nonetheless, it is worthwhile seeing what McMillan does with this argument. He tells us that we can "read the first-person experience from behavior in a fairly accurate and informative way." He uses the example of a father gazing at his young child and notes that it is not unreasonable to infer that he is experiencing loving and nurturing feelings. It is, indeed, not unreasonable to draw such an inference. But it is far more reasonable to infer that the father is experiencing a cacophony of feelings, including, but not limited to, love, concern, anxiety, pride, envy, hope, and sadness (Stern 1995, 18-58). If we are able to distinguish which of these feelings is dominant at any given moment—which we are—and if we are also able to track subtle shifts in such feelings... (shrink)

Traditionally, the problem of evil, in its various formulations, has been one of the strongest objections against perfect being theism. In the voluminous literature on this problem, the motif of evil has usually been discussed with respect to human flourishing. In recent decades more focused attention has been paid to animal suffering and the philosophical problems that such suffering poses for perfect being theists. However, this growing body of literature, in Anglo-American philosophical milieus, is largely aimed at sketching a specifically (...) Christian or Christianity-inflected theodicy that would reconcile animal suffering with the existence of an omni-God. In contrast, there are few, if any, systematic attempts to put forth a Hindu theodicy that aims to offer morally justifiable reasons that God has for allowing animal suffering. In this article, we address this scholarly lacuna by illustrating how a Hindu perfect being theist might respond to the problem of animal suffering. (shrink)
