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)

Philip Pettit's narrative of the eclipse of republican by liberal liberty in late eighteenth-century Britain adds colour and plausibility to his analytical contrast between republican and liberal liberty. The narrative supports his argument that republicanism and liberalism can be helpfully contrasted in terms of non-domination and non- interference conceptions of liberty. While the narrative has not been scrutinized in the literature, it is in fact flawed. The flaws raise new questions about how stringent a value liberty as non-domination is and (...) what motivated the value. The flaws also raise new questions about the significance of liberty as non-interference within the very strand of liberalism that Pettit focuses upon. Finally, the article casts doubt on some aspects of Quentin Skinner's interpretation of republican liberty. (shrink)

Ghosh introduces the term 'plastic turn' and gives a new direction for how we can interpret and experience the turn today. By what he calls the material-aesthetic, he opens up a fresh direction in our experience and understanding of plastic through the correspondence that plastic as a material brings with the aesthetic that it inspires and figures"-.

In the domain of legal information retrieval, an important challenge is to compute similarity between two legal documents. Precedents play an important role in The Common Law system, where lawyers need to frequently refer to relevant prior cases. Measuring document similarity is one of the most crucial aspects of any document retrieval system which decides the speed, scalability and accuracy of the system. Text-based and network-based methods for computing similarity among case reports have already been proposed in prior works but (...) not without a few pitfalls. Since legal citation networks are generally highly disconnected, network based metrics are not suited for them. Till date, only a few text-based and predominant embedding based methods have been employed, for instance, TF-IDF based approaches, Word2Vec and Doc2Vec based approaches. We investigate the performance of 56 different methodologies for computing textual similarity across court case statements when applied on a dataset of Indian Supreme Court Cases. Among the 56 different methods, thirty are adaptations of existing methods and twenty-six are our proposed methods. The methods studied include models such as BERT and Law2Vec. It is observed that the more traditional methods that rely on a bag-of-words representation performs better than the more advanced context-aware methods for computing document-level similarity. Finally we nominate, via empirical validation, five of our best performing methods as appropriate for measuring similarity between case reports. Among these five, two are adaptations of existing methods and the other three are our proposed methods. (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)

In a Common Law system, legal practitioners need frequent access to prior case documents that discuss relevant legal issues. Case documents are generally very lengthy, containing complex sentence structures, and reading them fully is a strenuous task even for legal practitioners. Having a concise overview of these documents can relieve legal practitioners from the task of reading the complete case statements. Legal catchphrases are (multi-word) phrases that provide a concise overview of the contents of a case document, and automated generation (...) of catchphrases is a challenging problem in legal analytics. In this paper, we propose a novel supervised neural sequence tagging model for the extraction of catchphrases from legal case documents. Specifically, we show that incorporating document-specific information along with a sequence tagging model can enhance the performance of catchphrase extraction. We perform experiments over a set of Indian Supreme Court case documents, for which the gold-standard catchphrases (annotated by legal practitioners) are obtained from a popular legal information system. The performance of our proposed method is compared with that of several existing supervised and unsupervised methods, and our proposed method is empirically shown to be superior to all baselines.

This paper presents four theorems that connect continuity postulates in mathematical economics to solvability axioms in mathematical psychology, and ranks them under alternative supplementary assumptions. Theorem 1 connects notions of continuity (full, separate, Wold, weak Wold, Archimedean, mixture) with those of solvability (restricted, unrestricted) under the completeness and transitivity of a binary relation. Theorem 2 uses the primitive notion of a separately continuous function to answer the question when an analogous property on a relation is fully continuous. Theorem 3 provides (...) a portmanteau theorem on the equivalence between restricted solvability and various notions of continuity under weak monotonicity. Finally, Theorem 4 presents a variant of Theorem 3 that follows Theorem 1 in dispensing with the dimensionality requirement and in providing partial equivalences between solvability and continuity notions. These theorems are motivated for their potential use in representation theorems. (shrink)

Since the conceptualization of unethical pro-organizational behavior ten years ago, scholarly interest in exploring this phenomenon has multiplied. Given a burgeoning body of empirical research, a review of unethical pro-organizational behavior literature is warranted. This study, therefore, systematically reviews the extant literature on unethical pro-organizational behavior and presents a comprehensive theory-based review of the past developments in this field. We classify previous studies based on their underlying theoretical perspectives and discuss the antecedents and consequences of unethical pro-organizational behavior in work (...) context. We also explicate the boundary conditions under which the influence of these antecedents gets accentuated or alleviated. Overall, this study synthesizes past knowledge to elucidate why, how, and when unethical pro-organizational behavior unfolds in the workplace. Finally, the gaps in the extant theorization are identified and an agenda for future research is proposed. (shrink)

Summarization of legal case judgement documents is a practical and challenging problem, for which many summarization algorithms of different varieties have been tried. In this work, rather than developing yet another summarization algorithm, we investigate if intelligently ensembling (combining) the outputs of multiple (base) summarization algorithms can lead to better summaries of legal case judgements than any of the base algorithms. Using two datasets of case judgement documents from the Indian Supreme Court, one with extractive gold standard summaries and the (...) other with abstractive gold standard summaries, we apply various ensembling techniques on summaries generated by a wide variety of summarization algorithms. The ensembling methods applied range from simple voting-based methods to ranking-based and graph-based ensembling methods. We show that many of our ensembling methods yield summaries that are better than the summaries produced by any of the individual base algorithms, in terms of ROUGE and METEOR scores. (shrink)

A fundamental issue in philosophy of perception is to understand the nature of experience and the relation of the experience with objects or states of affairs that is experienced. A prominent philosophical issue here is posed by the possibility of hallucinatory experiences, which are subjectively indistinguishable from veridical perception for the experiencer. The philosophical views in this matter can be grouped into three major positions on the basis of the nature of the subjective experience and relation of the subjective experience (...) with the object. These are the sense-data theories—which consider that the objects of perception are mental entities; the representative theories—according to which perception is a representation of the objects in the external world; and the naïve realist theories—which proclaim that the external objects are constitutive of the very perceptual experience and not a representation of it. Naïve realism claims it is the defence of common-sense notion regarding experience i.e. how experience seems to the experiencer upon introspective reflection on it. This position has a growing number of proponents in philosophy especially in the last two decades. But it also entails radical departure of established philosophical views regarding the nature of experience, the phenomenal character of experience, and the experiencer–object relation. In this paper, we critically examine naïve realism from two crucial aspects pertaining to it—the question of introspection being basis of naïve realist thesis, and the notion of primacy of perception over non-veridical forms of experiences. We find that there are significant problems which weaken the naïve realist thesis. (shrink)

Connected vehicle fleets have formed significant component of industrial internet of things scenarios as part of Industry 4.0 worldwide. The number of vehicles in these fleets has grown at a steady pace. The vehicles monitoring with machine learning algorithms has significantly improved maintenance activities. Predictive maintenance potential has increased where machines are controlled through networked smart devices. Here, benefits are accrued considering uptimes optimization. This has resulted in reduction of associated time and labor costs. It has also provided significant increase (...) in cost benefit ratios. Considering vehicle fault trends in this research predictive maintenance problem is addressed through hybrid deep learning-based ensemble method (HDLEM). The ensemble framework which acts as predictive analytics engine comprises of three deep learning algorithms viz modified cox proportional hazard deep learning (MCoxPHDL), modified deep learning embedded semi supervised learning (MDLeSSL) and merged LSTM (MLSTM) networks. Both sensor as well as historical maintenance data are collected and prepared using benchmarking methods for HDLEM training and testing. Here, times between failures (TBF) modeling and prediction on multi-source data are successfully achieved. The results obtained are compared with stated deep learning models. This ensemble framework offers great potential towards achieving more profitable, efficient and sustainable vehicle fleet management solutions. This helps better telematics data implementation which ensures preventative management towards desired solution. The ensemble method's superiority is highlighted through several experimental results.

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.

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 and we add a new modal variant to that class of logics. We also discuss the relative expressive power of the proposed logic in comparison to the standard (...) modal counterparts. (shrink)

The literature on the democratic legitimacy of judicial review and also on institutionalizing deliberative democracy neglects the possibility of employing juries rather than judges to determine bill-of-rights matters. This neglect is unfortunate, for there are findings emerging especially from deliberative polling that support the feasibility of such juries. Such feasibility would raise a new countermajoritarian concern with judicial review. The argument supporting this new concern also casts fresh light on the traditional countermajoritarian concern.

Current understanding of Mill as a founding father of liberalism is a Cold War creation. Discarding this conception opens the way to a general reassessment of his thought: who was the historical Mill? He did not define himself as liberal and there is no simple template. Most obviously he is a pluralist, defined by a plural heritage received through his father. This framework permitted great creativity in political and social theory, but it was diffuse. The one clear unifying theme is (...) a unique conception of a hierarchy of intellect founded on the inexorable accumulation of positive knowledge. The one important exception to this is political economy. What stands out overall is his individuality, where Mill embodies his own ideal. So apart from political economy, where he could be identified in more conventional terms, his nineteenth-century legacy was personal and incalculably diffusive rather than doctrinaire. This left it ripe for twentieth-century re-invention. (shrink)

The task of rhetorical role labeling is to assign labels (such as Fact, Argument, Final Judgement, etc.) to sentences of a court case document. Rhetorical role labeling is an important problem in the field of Legal Analytics, since it can aid in various downstream tasks as well as enhances the readability of lengthy case documents. The task is challenging as case documents are highly various in structure and the rhetorical labels are often subjective. Previous works for automatic rhetorical role identification (...) (i) mainly used Conditional Random Fields over manually handcrafted features, and (ii) focused on certain law domains only (e.g., Immigration cases, Rent law), and a particular jurisdiction/country (e.g., US, Canada, India). In this work, we improve upon the prior works on rhetorical role identification by proposing novel Deep Learning models for automatically identifying rhetorical roles, which substantially outperform the prior methods. Additionally, we show the effectiveness of the proposed models over documents from five different law domains, and from two different jurisdictions—the Supreme Court of India and the Supreme Court of the UK. Through extensive experiments over different variations of the Deep Learning models, including Transformer models based on BERT and LegalBERT, we show the robustness of the methods for the task. We also perform an extensive inter-annotator study and analyse the agreement of the predictions of the proposed model with the annotations by domain experts. We find that some rhetorical labels are inherently hard/subjective and both law experts and neural models frequently get confused in predicting them correctly. (shrink)

In this technology-driven Digital Age, Management Education is primarily engaged in development of skills and techno-economic competence of students with dominant thrust on sharpening their rational faculties and quantitative ability. Deeper questions and nobler qualittative issues like Spirituality, Corporate Social Responsibility and Ethics are naturally assigned low priority in the rush for money, career, fame, power and position both at the individual and organizational levels. The present paper engages in a Qualitative Research by conducting Focus group Interviews among Participants at (...) the Undergraduate level who had taken up Management Education. After content analysis of the responses the authors highlight their observations on the existing gaps in prevailing management education leading to failure of the present system in charging the students with a deeper Meaning of Work and a higher Purpose of Life. The paper then delves into exploration in pertinent tenets of Classical Indian Wisdom to enrich the spectrum of Management education with insights on Humanistic Philosophy, Holistic Learning, Enlightened CSR and Ethics, and Inspirational Leadership towards creating a better and more humane future for modern organizations.

This book provides a radical rethinking of the prominent Indian thinker Rabindranath Tagore, exploring how his philosophy of education relates to the ideas of Western theorists such as Kant, Plato and Aristotle. Tagore's thoughts on pedagogy, university and formal education are subjected to a fascinating critique within Ghosh's transcultural framework, referencing a wide range of thinkers across varying time periods, places, and cultures, and developing a greater sensitivity to other traditions, languages, and forms of thinking and writing. The book (...) changes the way we have so far thought about the educationist Tagore, and will be of interest to scholars and specialists of literature, Indian history, and philosophy of education. It is political, deeply philosophical and has a transcultural take on our understanding of a variety of issues relating to Tagore and to philosophy of education in general. (shrink)

Six cardinal leadership virtues based on Aristotelian and Confucian typology were advanced through this study by developing a measurement instrument and examining its predictive validity by studying the causal association with perceived leader happiness. Based on a sample of 183 school principals engaged in various types of schools, the results of both exploratory and confirmatory factor analyses generated satisfactory empirical outcomes by finding adequate support for the overall leadership virtue scale and the constituent subscale elements. The paper concluded with the (...) theoretical and practical implications for this developed instrument of leadership virtue especially in the context of school education. The major contribution of the paper lies in developing a measurement scale of virtues for school leaders. (shrink)

In today's world the need for cultivating non-violence is becoming more pronounced. Gandhi extrapolated an ideal society based on truth and nonviolence. The Bombay Chronicle in its issue of 5th April, 1930, reported "...For the first time a nation is asked by its leader to win freedom by itself accepting all the suffering and sacrifice involved. Mahatma Gandhi's success does not, therefore, merely mean the freedom of India. It will also constitute the most important contribution that any country yet made (...) towards the elimination of force as an arbiter between one nation and another..." For him, two cardinal principles of life, non-violence and truth, were the essence of sociopolitical good. "Satyagraha" was Gandhi's gift to the world. The word was coined by him in South Africa. In the West it was known as passive resistance. Satyagraha signified pure soul-force. Truth or Love is the very substance of the soul. To quote Gandhi in this context: "Non-violence as supreme dharma is the proof of this power of Love. Nonviolence is a dormant state. In the working state, it is Love, ruled by Love, the world goes on.... we are alive solely because of Love....we are all ourselves the proof of this..." In a centrifugal world, Gandhi's views expressed on non-violence and love are guidance to the world today more than at any other time. (shrink)
