It is often argued that the indispensability of continuum models comes from their empirical adequacy despite their decoupling from the microscopic details of the modelled physical system. There is thus a commonly held misconception that temperature varying across a region of space or time can always be accurately represented as a continuous function. We discuss three inter-related cases of temperature modelling — in phase transitions, thermal boundary resistance and slip flows — and show that the continuum view is fallacious on (...) the ground that the microscopic details of a physical system are not necessarily decoupled from continuum models. We show how temperature discontinuities are present in both data (experiments and simulations) and phenomena (theory and models) and how discontinuum models of temperature variation may have greater empirical adequacy and explanatory power. The conclusions of our paper are: a) continuum idealisations are not indispensable to modelling physical phenomena and both continuous and discontinuous representations of phenomena work depending on the context; b) temperature is not necessarily a continuously defined function in our best scientific representations of the world; and c) that its continuity, where applicable, is a contingent matter. We also raise a question as to whether discontinuous representations should be considered truly de-idealised descriptions of physical phenomena. (shrink)

Built-in decision thresholds for AI diagnostics are ethically problematic, as patients may differ in their attitudes about the risk of false-positive and false-negative results, which will require that clinicians assess patient values.

I examine social capital’s impact on financial reports. Based on the social capital literature, I predict that the quality of the financial reports is higher when a firm is headquartered in a region with high social capital. Consistent with this prediction, I find that the firms that are headquartered in this type of region in the USA have a lower probability of committing fraud by misrepresenting financial information. Further, I find that the firms in regions with high social capital have (...) lower levels of discretionary accruals and much more readable annual reports. (shrink)

Convolutional neural networks (CNNs) are increasingly widely used in psychology and neuroscience to predict how human minds and brains respond to visual images. Typically, CNNs represent these images using thousands of features that are learned through extensive training on image datasets. This raises a question: How many of these features are really needed to model human behavior? Here, we attempt to estimate the number of dimensions in CNN representations that are required to capture human psychological representations in two ways: (1) (...) directly, using human similarity judgments and (2) indirectly, in the context of categorization. In both cases, we find that low-dimensional projections of CNN representations are sufficient to predict human behavior. We show that these low-dimensional representations can be easily interpreted, providing further insight into how people represent visual information. A series of control studies indicate that these findings are not due to the size of the dataset we used and may be due to a high level of redundancy in the features appearing in CNN representations.

So-called ‘distinctively mathematical explanations’ (DMEs) are said to explain physical phenomena, not in terms of contingent causal laws, but rather in terms of mathematical necessities that constrain the physical system in question. Lange argues that the existence of four or more equilibrium positions of any double pendulum has a DME. Here we refute both Lange’s claim itself and a strengthened and extended version of the claim that would pertain to any n-tuple pendulum system on the ground that such explanations are (...) actually causal explanations in disguise and their associated modal conditionals are not general enough to explain the said features of such dynamical systems. We argue and show that if circumscribing the antecedent for a necessarily true conditional in such explanations involves making a causal analysis of the problem, then the resulting explanation is not distinctively mathematical or non-causal. Our argument generalises to other dynamical systems that may have purported DMEs analogous to the one proposed by Lange, and even to some other counterfactual accounts of non-causal explanation given by Reutlinger and Rice.

There is a major debate as to whether there are non-causal mathematical explanations of physical facts that show how the facts under question arise from a degree of mathematical necessity considered stronger than that of contingent causal laws. We focus on Marc Lange’s account of distinctively mathematical explanations to argue that purported mathematical explanations are essentially causal explanations in disguise and are no different from ordinary applications of mathematics. This is because these explanations work not by appealing to what the (...) world must be like as a matter of mathematical necessity but by appealing to various contingent causal facts. (shrink)

(Longer version - work in progress) Various accounts of distinctively mathematical explanations (DMEs) of complex systems have been proposed recently which bypass the contingent causal laws and appeal primarily to mathematical necessities constraining the system. These necessities are considered to be modally exalted in that they obtain with a greater necessity than the ordinary laws of nature (Lange 2016). This paper focuses on DMEs of the number of equilibrium positions of n-tuple pendulum systems and considers several different DMEs of these (...) systems which bypass causal features. It then argues that there is a tension between the modal strength of these DMEs and their epistemic hooking, and we are forced to choose between (a) a purported DME with greater modal strength and wider applicability but poor epistemic hooking, or (b) a narrowly applicable DME with lesser modal strength but with the right kind of epistemic hooking. It also aims to show why some kind of DMEs may be unappealing for working scientists despite their strong modality, and why some DMEs fail to be modally robust because of making ill-informed assumptions about their target systems. The broader goal is to show why such tensions weaken the case for DMEs for pendulum systems in general. (shrink)

Educational institutions rely on academic citizenship behaviors to construct knowledge in a responsible manner. However, they often struggle to contain the unlawful reuse of knowledge by some learning communities. This study draws upon secondary data from two televised episodes describing contract cheating practices prevalent among international student communities. Against this background, we have investigated emergent teaching and learning structures that have been extended to formal and informal spaces with the use of mediating technologies. Learners’ interactions in formal spaces are influenced (...) by ongoing informal social experiences within a shared cultural context to influence learners’ agency. Building upon existing theories, we have developed an analytical lens to understand the rationale behind cheating behaviors. Citizenship behaviors are based on individual and collective perceptions of what constitutes as acceptable or unacceptable behavior. That is, learners who are low in motivation and are less engaged with learning may collude; more so, if cheating is not condemned by members belonging to their informal social spaces. Our analytical lens describes institutional, cultural, technological, social and behavioral contexts that influence learner agency. (shrink)

The chemist and philosopher Michael Polanyi was one of the first twentieth-century scientists to propose a program to resolve the internal conflict of the modern Enlightenment: scientific detachment and moral nihilism with humanist values. Stefania Jha’s intellectual biography places Polanyi in the context of his time and culture, analyzes his key philosophical ideas, and explicates the application—and at times misappropriation—of his work. Polanyi’s method was not laid out in his published works, and his vocabulary tends to make his writings difficult (...) to understand. By exposing the structure of his theory of tacit knowing, and by tracing the growth of his thinking, Jha shows how the various elements of his thought are integrated. Through examination of his philosophical roots in Kant and the complexity of his evolving thought, she counteracts the popular notion that Polanyi’s philosophy stands apart from the western philosophic tradition. Jha’s deep analysis makes Polanyi’s shift of focus from science to philosophy more intelligible, his philosophy more approachable, and the causes he championed—such as the freedom of science and cultural freedom—more understandable. Applying his notion of tacit knowing in practical directions, Jha seeks to bring the study of Polanyi’s philosophy out of the specialists’ enclave and into such fields as ethics and clinical medicine.

Lakatos is considered to be a Popperian who adapted his Hegelian-Marxist training to critical philosophy. I claim this is too narrow and misses Lakatos' goal of understanding scientific inquiry as heuristic inquiry—something he did not find in Popper, but found in Polanyi. Archival material shows that his ‘new method' struggled to overcome what he saw as the Popperian handicap, by using Polanyi.

The day to day experiences of answering machine messages, written notes, postcard messages, etc. and our intuitions regarding these seem to contradict the traditional assumptions in the semantics of indexicals. The primary analytical scope of the article is to undertake an analysis of Allyson Mount’s convergence of perspectives-based account of indexical reference and see whether it is able to successfully meet the challenges faced by Stefano Predelli’s intended context of interpretation approach towards the semantics of indexicals, thereby providing a viable (...) solution to the Answering Machine Paradox.

A reasoned argument or tarka is essential for a wholesome vāda that aims at establishing the truth. A strong tarka constitutes of a number of elements including an anumāna based on a valid hetu. Several scholars, such as Dharmakīrti, Vasubandhu and Dignāga, have worked on theories for the establishment of a valid hetu to distinguish it from an invalid one. This paper aims to interpret Dignāga’s hetu-cakra, called the wheel of grounds, from a modern philosophical perspective by deconstructing it into (...) a simple probabilistic mathematical model. The objective is to understand how and why a vāda based on a probabilistically weaker hetu can degrade into a Jalpa or vitaṇḍā. To do so, the paper maps the concept of ‘Bounded Rationality’ onto the hetu-cakra. Bounded Rationality, an idea coined by the management thinker Herbert Simon, is often employed in understanding decision-making processes of rational agents. In the context of this paper, the concept would state that the prativādin and ālocaka (debater) may not hold unbounded information to back their pratijñā (proposition). The paper argues that within the probabilistically deconstructed hetu-cakra model, most people argue in the ‘Zone of Bounded Rationality’, and thus, the probability of a debate degrading into Jalpa or vitaṇḍā is high. -/- .

In this response to Jeff Pflug’s review of my dissertation Michael Polanyi’s Integrative Philosophy, I note that Pflug focused on my discussion of possible extension of Polanyi’s epistemology; he has also taken my statements on scientific truth out of context. In addition, he ignored the four major elements of the dissertation, thereby not giving the reader a “map” to the meaning and the rationale of the work – an intellectual biography of Polanyi.

For the last two centuries the novel has been the predominant literary genre; but the generic identity of the novel is far from established. Attempts to define the novel have focussed on formal features of particular types of texts, with the result that definitions of “the” novel have merely canonized one or another of the innumerable novelistic manifestations—Bildungsroman, eighteenth-century English novels, novels of the kind George Eliot or Henry James or Marcel Proust or Feodor Dostoevsky wrote, etc. By basing themselves (...) upon such formal attributes, such definitions exclude a vast number of potential texts on essentially normative grounds. Further, the history of the novel has outgrown and contradicted those conceptions; no sooner than a theory has been formulated, the novel itself has moved forward, adapting to changing conditions and substituting for those formal properties a set of new ones, thus rendering the theories obsolete and revealing the inadequacy of formalist categories to define the genre. This predicament is certainly not unique to the theory of the novel but rather a necessary concomitant of any theoretical project; what makes any attempt to theorize about the novel particularly vulnerable is the genre's resistence to formalist analysis, its lack of precisely those organizing categories upon which a formalist theory of any genre can be built.

Ethical morality is one of the significant issues in self-driving cars. The paper provides a newer approach to solve the ethical decision problems in self-driving cars until there is no concrete ethical decision to all problems. This paper gives a two-way approach to solve a problem, with first being the mapping of problem to the solution already known or which has a fixed set of solutions and action priorities defined to a problem previously. Now, if no solution is found or (...) mapping is unsuccessful, then the second stage activates, where the solution from Deep Q-learning model is calculated. It estimates the best Q value and returns that solution or action which maximizes the reward at that instance. The reward function is designed with decreasing priorities and acts accordingly, where the users can change or define their priorities if needed. The case study and results show that the solution that is present in the paper will lead to solving ethical morality problems in self-driving cars up to a great extent. (shrink)

Group Violence Interventions combine a focused deterrence law enforcement approach with community mobilization and social services. The current study qualitatively examines Project Longevity, Connecticut's largest GVI initiative, to contribute to the limited literature on implementation of gun violence reduction strategies. Relying on interviews with 24 of Project Longevity law enforcement and non-law enforcement partners, we explore the establishment of interagency collaboration, which was viewed by study participants as the most pressing implementation challenge of Project Longevity. Our case study results offer (...) important lessons to practitioners responsible for implementing GVI strategies. (shrink)

Friendship is such a unique relationship among human beings that even philosophers have considered it as a vital factor in the social life of humans. Aristotle is one such philosopher who has given a significant amount of space to friendship among the mortals. Friendship is relational in nature and thereby calls for various discourses between the ‘self’ and the ‘other’. In this regard, McDowell’s idea of ‘second nature’ is significant since it adds that extra responsibility, willingness and rational capacity enabling (...) us to live in communion. However, friendship has a peculiar relation with politics as in this world one cannot deny that there will be enemies as well as friends. In this respect, Derrida situates Schmitt’s The Concept of the Political as an evolution in the politics of friendship either in the form of ‘dissolution’ or in the form of ‘upheaval’. I have tried to analyse Derrida’s views in the background of the contrast between the ‘dying sage’ and the ‘living fool’ where the discourses change between friendship and politics. Friendship and politics are not alien to Indian philosophy as well. The relationships between Kṛṣṇa and Arjuna, between Karṇa and Duryodhana in the Mahābhārata could be analysed from various angles. Friendship has a trans-political character which has been addressed in the paper by showing the hermeneutic of solidarity after Gadamer. This paves way for a reappraisal of the Aristotelian conception of friendship. I think that the discourses between friendship and politics bring about new insights regarding the notion of friendship itself, and it is important to recognise that difference and reciprocity may exist together without distressing the relationship and at the same time with the (dis)closure of the self.

A venture in a less traversed terrain of Indian scholarship, this article looks at the transformation in the value regimes that go into the making of colours in the Indian milieu. At one level, this study traces the sacredness imbued in colours and at another level the article delves into the genealogy that gives rise to a complex where colour, colonial investment in the economy of colours, values and experiential dynamics enshrined in the imageries and practices associated with colours all (...) come together. With these entanglements, the idea is to engage with the social fabrics and the politics of colours in the Indian milieu. In this rendering, the distinction between values and forms collapses giving us in turn a field of aesthetic experience. Mobilizing a wide range of registers, this story is narrated with key rubrics, such as, ambiguous location of colour in the discourse on visuality, social and cultural life of colours and the manner in which Western science and modernity has influenced the values pertaining to colours. However, the core anxiety is parked on the relation between colour, aesthetic experience and the question of value. (shrink)

Journal of Human Values, Volume 28, Issue 2, Page 143-160, May 2022. Recent decades have witnessed an unprecedented amount of conflict around visual representations in India. The field of the visual is the new terrain for rumour mongering and for maiming uncomfortable oppositional voices. With the fast-spreading mobile culture, penetrating social media and continued legacy of the pictorial as an embodiment of the real, the visual has taken over both the oral as well as the written words in its usefulness (...) to serve the political. Can we simply comprehend such a visual aggression by taking recourse in the enhanced role of visual media in our everyday life, along the lines of a ‘visual turn’? Is the visual sphere another surface of politics? With these key questions, this article revisits certain contemporary visual events by focusing on words that float in public spaces from streets to television screens. On a broader terrain, with an emphasis on aesthetics, the article relooks at an often-settled equation between the visual and the political on the one hand and the question of the visual as an archive of the contemporary on the other. Following Rancière’s notion of aesthetics as a field of the distribution of the sensible, this article has tried to focus on vernacular words circulating outside the confines of the literature and create a domain of political communication hitherto ignored by scholars.
