This paper presents an attempt to bridge the gap between logical and cognitive treatments of strategic reasoning in games. There have been extensive formal debates about the merits of the principle of backward induction among game theorists and logicians. Experimental economists and psychologists have shown that human subjects, perhaps due to their bounded resources, do not always follow the backward induction strategy, leading to unexpected outcomes. Recently, based on an eye-tracking study, it has turned out that even human subjects who (...) produce the outwardly correct ‘backward induction answer’ use a different internal reasoning strategy to achieve it. The paper presents a formal language to represent different strategies on a finer-grained level than was possible before. The language and its semantics help to precisely distinguish different cognitive reasoning strategies, that can then be tested on the basis of computational cognitive models and experiments with human subjects. The syntactic framework of the formal system provides a generic way of constructing computational cognitive models of the participants of the Marble Drop game. (shrink)

How do people reason about their opponent in turn-taking games? Often, people do not make the decisions that game theory would prescribe. We present a logic that can play a key role in understanding how people make their decisions, by delineating all plausible reasoning strategies in a systematic manner. This in turn makes it possible to construct a corresponding set of computational models in a cognitive architecture. These models can be run and fitted to the participants’ data in terms of (...) decisions, response times, and answers to questions. We validate these claims on the basis of an earlier game-theoretic experiment about the turn-taking game “Marble Drop with Surprising Opponent”, in which the opponent often starts with a seemingly irrational move. We explore two ways of segregating the participants into reasonable “player types”. The first way is based on latent class analysis, which divides the players into three classes according to their first decisions in the game: Random players, Learners, and Expected players, who make decisions consistent with forward induction. The second way is based on participants’ answers to a question about their opponent, classified according to levels of theory of mind: zero-order, first-order and second-order. It turns out that increasing levels of decisions and theory of mind both correspond to increasing success as measured by monetary awards and increasing decision times. Next, we use the logical language to express different kinds of strategies that people apply when reasoning about their opponent and making decisions in turn-taking games, as well as the ‘reasoning types’ reflected in their behavior. Then, we translate the logical formulas into computational cognitive models in the PRIMs architecture. Finally, we run two of the resulting models, corresponding to the strategy of only being interested in one’s own payoff and to the myopic strategy, in which one can only look ahead to a limited number of nodes. It turns out that the participant data fit to the own-payoff strategy, not the myopic one. The article closes the circle from experiments via logic and cognitive modelling back to predictions about new experiments. (shrink)

There are two important aspects of any democratic decision: aggregation of preferences and deliberation about preferences. They are essential and complementary components of any decision making process. While the well-studied process of aggregation focuses on accumulating individual preferences without discussing their origin [4], deliberation can be seen as a conversation through which individuals justify their preferences, a process that might lead to changes in their opinions as they get influenced by one another. Till now, there has been a lot of (...) work on the ‘aggregation’ aspect (e.g., [12, 14, 6]). However, some recent work has focussed on the deliberation aspect as well [8, 9, 10, 15]. Sometimes, deliberation does not lead to unanimity in preferences, but the discussion can lead to some ‘preference uniformity’ (see how deliberation can help in bypassing social choice theory’s impossibility results in [5]), which might facilitate their eventual aggregation. In addition, the combination of both processes provides a more realistic model for decision making scenarios. In light of this status quo, our focus is on the formal study of achieving such preference uniformities, e.g., single-peaked, single-caved, single-crossing, value-restricted, best-restricted, worst-restricted, medium-restricted, or group-separable profiles. In this short abstract we provide our preliminary ideas towards achieving singlepeakedness of preference profiles via deliberation. In what follows, we define two preference upgrade operators based on [8, 9] and provide a preliminary discussion on how single-peaked preference profiles can be achieved through such operations. We will delve into the details of the logical language in the main paper. (shrink)

This book reconceptualizes the ancient philosophy of "dualism" and a "trinity" applied to classical and quantum nonequilibrium phenomena. In addition to classical mechanics and electrodynamics, a remarkable connection of this philosophy with quantum mechanics is established which can be useful for quantum computing and the development of quantum artificial intelligence. Packed with the recent theoretical models, quantum simulations of black holes, and experimental observations of quantum phase transitions, this book brings a holistic approach that can be useful to refine the (...) concept of the 'Creation', evolution of the Universe from the condensed state of matter, and explain the artificial vision.

When agents know a protocol, this leads them to have expectations about future observations. Agents can update their knowledge by matching their actual observations with the expected ones. They eliminate states where they do not match. In this paper, we study how agents perceive protocols that are not commonly known, and propose a semantics-driven logical framework to reason about knowledge in such scenarios. In particular, we introduce the notion of epistemic expectation models and a propositional dynamic logic-style epistemic logic for (...) reasoning about knowledge via matching agentsÊ expectations to their observations. It is shown how epistemic expectation models can be obtained from epistemic protocols. Furthermore, a characterization is presented of the effective equivalence of epistemic protocols. We introduce a new logic that incorporates updates of protocols and that can model reasoning about knowledge and observations. Finally, the framework is extended to incorporate fact-changing actions, and a worked-out example is given. © 2013 Elsevier B.V. (shrink)

We make a proposal for formalizing simultaneous games at the abstraction level of player’s powers, combining ideas from dynamic logic of sequential games and concurrent dynamic logic. We prove completeness for a new system of ‘concurrent game logic’ CDGL with respect to finite non-determined games. We also show how this system raises new mathematical issues, and throws light on branching quantifiers and independence-friendly evaluation games for first-order logic.

As students progress towards their PhD degrees, they will become more independent and practitioner-like; for those moving into academia, it is often assumed the programs of their PhD mentors will serve as prototypes for their own successful research programs. However, the author's research program as an Assistant Professor led him in directions never considered as a graduate student. The author had to make significant decisions in choosing a primary audience, finding an overarching theme, defining the individual problems, and developing these (...) problems into researchable projects. Infrastructure-related issues associated with the author's research program were also considered. The details of his journey from the end of his doctoral degree to his current position as an Assistant Professor are described in this article. (shrink)

Cet article s’intéresse aux gestes performatifs et aux pas de danse à travers lesquels les femmes colonisées de la bourgeoisie négocièrent les tensions profondes entre le patriarcat indien et la domination coloniale au Bengale (en Inde) à la fin du xixe et au début du xxe siècle. La première partie examine la contribution du Prix Nobel de poésie, Rabindranath Tagore (1861-1941), au développement de la danse au Bengale et replace sa pratique de danse au sein d’une discussion plus large sur (...) le genre et le nationalisme indien. La seconde partie explore l’intérêt de Tagore pour la mise-en-scène du genre et la décolonisation de la scène indienne à travers l’étude de ses lettres de voyage en Asie du Sud-Est. La troisième partie déplace le regard au-delà de l’idée d’auteur célèbre qui influence la plupart des écrits sur Tagore – poète et romancier, reconnu internationalement, notamment pour ses spectacles mettant les femmes au centre de la scène. À la place, cet article privilégie une lecture donnant à voir le travail et l’écriture sur la danse de sa belle-fille, Pratima Devi. Cette dernière conçut, supervisa, et travailla sur beaucoup des œuvres dramatiques et dansées de Tagore au Bengale, renversant ainsi beaucoup des normes qui étaient imposées par un nationalisme indien patriarcal sur les femmes issues de la bourgeoisie. Ainsi, cette étude incite à comprendre les relations entre le travail du corps des femmes dans et hors de la scène colonisée de la danse du xxe siècle bengali. (shrink)

In His Learned Book, Development Of Nyaya Philosophy And Its Social Context Professor Sibajiban Bhattacharyya Has Traced The History Of Nyaya Philosophy With Reference To Its Social Contexts. That This System Of Philosophy, Darsana, Is Not Unnecessarily Abstract But Has Taken Congizance Of Its Theoretical Ancestry As Well As Practical Circumstances Will Be Evident To The Perceptive Reader. As A Branch Of Knowledge, Vidya, Philosophy As Darsana Was Known In India For A Long Time. In Kautilya'S Arthasastra The Recognized (...) Branches Of Knowledge Are Four: (I) The Three Vedas (Trayi), (Ii) Trade And Commerce (Varta); (Iii) Law And Order (Dandaniti) And (Iv) Anvisiki, Which According To Kautilya Means Sankhya, Yoga And Lokayata. However, Later On Anvisiki Stood For Logic And Metaphysic. In The History Of Indian Philosophy The First Use Of The Term Darsana Has Been Attributed To Haribhadrasuri, The Jaina Philosopher And Author Of The Sad Darsana Samuccaya. Nearly 400 Years After Haribhadrasuri The Term Darsana In The Current Sense Was Used By Sankaracarya In His Commentary On The Brahmasutra. In This Comprehensive Book Professor Bhattacharyya Has Dealt With The Works Of Mostof The Famous Nyaya Thinkers Like Gautama, Vatsyayana, Jayanta Bhatta, Bhasarvajna, Udayana, Vardhamana And Various Other Writers Down The Centuries. This Scholarly Book From The Pen Of Bhattacharyya Is Highly Readable And Informative. It Is Hoped That The Book Will Be Profitably Used By Researchers, Scholars And The General Reading Public.

This paper reviews the fate of the central ideas behind the complementary learning systems (CLS) framework as originally articulated in McClelland, McNaughton, and O’Reilly (1995). This framework explains why the brain requires two differentially specialized learning and memory systems, and it nicely specifies their central properties (i.e., the hippocampus as a sparse, pattern-separated system for rapidly learning episodic memories, and the neocortex as a distributed, overlapping system for gradually integrating across episodes to extract latent semantic structure). We review the application (...) of the CLS framework to a range of important topics, including the following: the basic neural processes of hippocampal memory encoding and recall, conjunctive encoding, human recognition memory, consolidation of initial hippocampal learning in cortex, dynamic modulation of encoding versus recall, and the synergistic interactions between hippocampus and neocortex. Overall, the CLS framework remains a vital theoretical force in the field, with the empirical data over the past 15 years generally confirming its key principles. (shrink)

The welfare and protection of human subjects is critical to the integrity of clinical investigation and research. Institutional review boards were thus set up to be impartial reviewers of research protocols in clinical research. Their main role is to stand between the investigator and her human subjects in order to ensure that the welfare of human subjects are protected. While there is much literature on the conflicts of interest faced by investigators and researchers in clinical investigations, an area that is (...) less explored is CIs that may affect members of IRBs during the institutional ethics review of clinical investigations. This article examines the notion of CIs in clinical research and attempts to develop a framework for a clearer and more balanced approach to identifying CIs that may influence members of IRBs and impede their independence. It will also apply the proposed framework to demonstrate how IRBs possess, or at least may appear to possess, forms of financial CIs and non-financial CIs. The proper identification and management of these CIs is critical to preserving the integrity of clinical investigations and achieving the primary aim of human subjects protection. (shrink)

Contributed research papers presented at International Conference on "Importance of Commentaries for Understanding Sanskrit Text", organized by Department of Sanskrit, University of Gour Banga, Malda on 5th-6th April 2017.

In response to Ferrario _et al_’s 1 work entitled ‘Ethics of the algorithmic prediction of goal of care preferences: from theory to practice’, we would like to point out an area of concern: the risk of artificial intelligence (AI) paternalism in their proposed framework. Accordingly, in this commentary, we underscore the importance of the implementation of safeguards for AI algorithms before they are deployed in clinical practice. The goal of documenting a living will and advanced directives is to convey personal (...) preferences regarding the acceptance of therapies, including life support, for future use in case of losing one’s capacity. This is standard practice in the care of incapacitated critically ill patients as it is considered to extend the individual’s autonomy. Notably, most of the documents that intensivists encounter in clinical practice are written in a generic fashion and lack context. This problem usually leads to the reliance on... (shrink)

PurposeThe purpose of this study is to identify the major factors influencing the adoption of health-care wearables in generation Z (Gen Z) customers in India. A conceptual framework using push pull and mooring (PPM) adoption theory was developed.Design/methodology/approachData was collected from 208 Gen Z customers based on 5 constructs related to the adoption of health-care wearables. Confirmatory factor analysis and structural equation modelling was used to analyse the responses. The mediation paths were analysed using bootstrapping method and examination of the (...) standardized direct and indirect effects in the model.FindingsThe study results indicated that the antecedent factors consisted of push (real-time health information availability), pull (normative environment) and mooring (decision self-efficacy) factors. The mooring factor (MOOR) was related to the push factor but not the pull factor. The MOOR, in turn, was related to the switching intention of Gen Z customers for health wearables adoption.Research limitations/implicationsThe research study extended the literature related to the PPM theory in the context of the adoption of health wearables among Gen Z customers in India.Practical implicationsThe study outcome would enable managers working in health wearable organizations to understand consumer behaviour towards health wearables.Social implicationsThe use of health wearables among Gen Z individuals would lead to future generations adopting a healthy lifestyle resulting in an effective workforce and better economy.Originality/valueThis was one of the few studies which have explored the PPM theory to explore the factors for the adoption of health wearables among Gen Z customers in India.

We discuss a simple logic to describe one of our favourite games from childhood, hide and seek, and show how a simple addition of an equality constant to describe the winning condition of the seeker makes our logic undecidable. There are certain decidable fragments of first-order logic which behave in a similar fashion with respect to such a language extension, and we add a new modal variant to that class. We discuss the relative expressive power of the proposed logic in (...) comparison to the standard modal counterparts. We prove that the model checking problem for the resulting logic is \(\textsf{P}\) -complete. In addition, by exploring the connection with related product logics, we gain more insight towards having a better understanding of the subtleties of the proposed framework. (shrink)
