Quantum theories constructed on the noncommutative spacetime called the Groenewold–Moyal plane exhibit many interesting properties such as Lorentz and CPT noninvariance, causality violation and twisted statistics. We show that such violations lead to many striking features that may be tested experimentally. These theories predict Pauli forbidden transitions due to twisted statistics, anisotropies in the cosmic microwave background radiation due to correlations of observables in spacelike regions and Lorentz and CPT violations in scattering amplitudes.

This paper is an attempt to see the similarity between the Shankara’s notion of Ätman and Husserl’s Transcendental Ego. Both thinkers, Husserl and Shankara trace true knowledge to the transcendental self. The former describes the self as the embodiment of absolute knowledge that transcends the limitations of the body, the senses and the intellect. In the state of bondage and ignorance, this Transcendental Ego is oblivious of its ontological and cognitive priority or transcendence and seeks knowledge in the natural world (...) of relative truths. It forgets that this world is merely an appearance (vivarta) rooted in the Ᾱtman which is identical with Brahman. (shrink)

Vedānta is one of the oldest philosophical systems. While there are many detailed commentaries on Vedānta, there are very few mathematical descriptions of the different concepts developed there. This article shows how ideas from theoretical computer science can be used to explain Vedānta. The standard ideas of transition systems and modal logic are used to develop a formal description for the different ideas in Vedānta. The generality of the formalism is illustrated via a number of examples including saṃsāra, Patañjali’s Yogasūtras, (...) karma, the three avasthās from the Māṇḍūkya Upaniṣad and the key difference between advaita and dvaita in relation to mokṣa.

Scientific inference aims to understand the external world and the influence of our actions on it, and arises as an interaction of hypothesis, observation and inferential procedures. Of these, only the observations originate in the external world, although even they are the perceptions of the observer. Nonuniqueness poses a great problem to objective scientific inference; this book discusses the causes of nonuniqueness and suggests that they are not entirely removable. It argues that truth is not manifest and that progress in (...) science is not sequential but is achieved by tentative theorisation and systematic error elimination. (shrink)

Audits of the informed consent process are a key element of a clinical research quality assurance program. A systematic approach to such audits has not been described in the literature. In this paper we describe two components of the audit. The first is the audit of the informed consent document to verify adherence with federal regulations. The second component is comprised of the audit of the informed consent conference, with emphasis on a real time review of the appropriate communication of (...) the key elements of the informed consent. Quality measures may include preparation of an informed consent history log, notes to accompany the informed consent, the use of an informed consent feedback tool, and the use of institutional surveys to assess comprehension of the informed consent process.

In this paper we show how defeasible logic could formally account for the non-monotonic properties involved in motivational attitudes like intention and obligation. Usually, normal modal operators are used to represent such attitudes wherein classical logical consequence and the rule of necessitation comes into play, i.e., ⊢A/⊢ □A, that is from ⊢A derive ⊢ □A. This means that such formalisms are affected by the Logical Omniscience problem. We show that policy-based intentions exhibit non-monotonic behaviour which could be captured through a (...) non-monotonic system like defeasible logic. To this end we outline a defeasible logic of intention that specifies how modalities can be introduced and manipulated in a non-monotonic setting without giving rise to the problem of logical omniscience. In a similar way we show how to add deontic modalities defeasibly and how to integrate them with other motivational attitudes like beliefs and goals. Finally we show that the basic aspect of the BOID architecture is captured by this extended framework. (shrink)

Agrobiodiversity is an evident outcome of a long-lasting human–nature relationship, as the continuous use, conservation and management of crops has resulted in biological as well as cultural diversity of seeds and breeds. This paper aims to understand the interlocking of formal and informal seed supply routes by considering the dynamic flow of seeds within networks across the intersections of gender, ethnicity and age in South India as social categories structuring human–nature relations. This changing relationship under formal and informal institutional settings (...) has consequences on performance for men and women in rice seed systems. Undertaking an empirical analysis of the organization of seed management and exchange, we seek to shed light on the gendered organization of agrobiodiversity as a social network. The study builds on Net-Map interviews conducted in 2012, embedded in the larger BioDIVA project in the district of Wayanad in Kerala, India. Based on network analysis, the interactive method employed has enabled identification of important actors in the seed system and the characteristics of their relationships. We look into the gendered structure of information exchange regarding seed varieties and actual seed transactions, while also examining clusters of actors collaborating regarding seed supply. Finally, we identify the institutional gap concerning seed sources left by formal and informal institutions, like the availability of varieties. We show how informal and formal seed systems coexist and overlap due to actors moving between systems and argue that the degree and areas of overlap are shaped by gendered human–nature relations.

The idea to work on this topic was come to my mind when I came across Masaaki Hattori’s comment that Dinnaga has accepted Bhartrhari’s views regarding the meaning of a sentence although their theories of word meaning are completely different from each other. According to Bhartrhari, in all phenomenal entities there are two elements viz. jati and vyakti; jati refers to the real element and vyakti to the unreal. Vyakti suffer changes, whereas jati remains constant. Again according to him the (...) real unit of language is a sentence, and not words or letters, because only a sentence conveys one full idea of the speaker. It’s meaning is also an instantaneous flash of pratibha or intuition, which has no parts. Dinnaga, on the other hand did not accept the reality of word‐ meaning (samanya),but maintained that words deal directly with conceptual images or vikalpas, which are purely subjective constructions of the mind, and therefore there can be no direct connection between words and external objects. The function of a word in a sentence is similar to the function of an inferential mark (linga) in the process of inference and it indicates its object through the exclusion of other things (apoha). Thus, there seems to be some contradictions in Dinnaga’s views on sentence meaning. But I think Dinnaga did not accept Bhartrhari’s views in toto. He could not possibly have done so. There is, however, a resemblance between Dinnaga and Bhartrhari in that each accepted that the primary unit of linguistic meaning is the entire sentence; the meaning of an individual word is abstracted from the whole meaning of the sentence. It is only in that respect that the two philosophers can be said to have roughly the same theory of sentential meaning. (shrink)

Buddhist logicians have rejected the reality of universals on the one hand, and, on the other hand, given a substitute in the form of the doctrine of Apoha. The doctrine of apoha first appears in Dinnaga’s Pramanasamuccaya, according to which words and concepts are negative by their very nature. They proceed on thebasis of negation. They express their own meaning only by repudiating their opposite meaning. The Buddhist logicians talk of two types of knowledge, viz., pratyaksa, which is non- relational (...) and anumana, which is relational. They accept nirvikalpaka pratyaksa as a pure pratyaksa, and savikalpaka pratyaksa has been merged with anumana by them. According to them, cognition is either a direct awareness of an object, which is independent of any mentalconstructionor it is an awareness of an object which is a mentalconstruction. Further, according to the Buddhist logicians inferences are of two kinds, viz., svarthanumana and pararthanumana. But they do not accept pararthanumana as a source of knowledge. Now, since perception is devoid of kalpana, perceptual knowledge is essentially non-linguistic and does not involve any general concept or universal. Thus,Apoha has no role to play in perceptual knowledge. On the other hand, savikalpaka pratyaksa and anumana are based on kalpana, thus according to the Buddhist logicians knowledge of universal is essential for both, savikalpaka pratyaksa and anumana.

German philosopher G. W. F. Hegel problematized the term “aesthetics” in his writings on art. This article attempts to capture the tension between Hegel's theory of art and philosophy of art and its impact on the subsequent theorization of art in the twentieth century as consumer or emancipatory. Music, poetry and plastic arts seem to resonate differently with philosophers such as Plato, Aristotle, Kant, Hegel and Adorno. Plato considered music soothing to the soul. In Aristotle, one could trace the oblique (...) beginnings of the tension between a theory of art and a philosophy of art as he questioned the role of art in philosophy. While Kant's approach is more formal and deals with concepts such as beauty, sublime, genius, and the status of aesthetic objects, Hegel grapples with the rational and emotional aspects of works of art which determine whether art is free or under the thralldom of nature. Both Kant and Hegel distinguished artistic from natural beauty. Critical theorists such as Adorno were also influenced by Hegel. Adorno's analysis of concepts such as mimesis forms an important part of his critique of culture industry. Adorno was also emphatic that classical art could only exist as a product of an epoch. Yet in its dialectical form, art serves as a critique of ideology. Progressively, from the nineteenth to the twentieth century, what began as a crevice between a philosophy of art and a theory of art became a chasm. Thus, begins a contentious relationship between art as a pursuit in itself and art for consumption, that is, art as an integral aspect of consumer culture. The new phenomenon of AI art also poses interesting questions about the paradigmatic shift in dynamics between human element and technology. This article would also attempt to trace how art continues to defy reification, while in the process being consumed constantly, recreating and reinventing itself. (shrink)

This timely book examines the rise of posthumanism as both a material condition and a developing philosophical-ethical project in the age of cloning, gene engineering, organ transplants and implants. Nayar first maps the political and philosophical critiques of traditional humanism, revealing its exclusionary and 'speciesist' politics that position the human as a distinctive and dominant life form. He then contextualizes the posthumanist vision which, drawing upon biomedical, engineering and techno-scientific studies, concludes that human consciousness is shaped by its co-evolution with (...) other life forms, and our human form inescapably influenced by tools and technology. Finally the book explores posthumanism's roots in disability studies, animal studies and bioethics to underscore the constructed nature of 'normalcy' in bodies, and the singularity of species and life itself. As this book powerfully demonstrates, posthumanism marks a radical reassessment of the human as constituted by symbiosis, assimilation, difference and dependence upon and with other species. Mapping the terrain of these far-reaching debates, Posthumanism will be an invaluable companion to students of cultural studies and modern and contemporary literature."--Page 4 of cover. (shrink)

Irregularity may occur on the earth’s surface in the form of mountains due to the imperfection of the earth’s crust. To explore the influence of horizontally polarized shear waves on mountains, we considered the fluid-saturated porous medium over an orthotropic semi-infinite medium with rigid and soft mountain surfaces for wave propagation. The mountain surface is defined mathematically as a periodic function of the time domain. The physical interpretation of materials’ structure has been explained in rectangular Cartesian coordinate system originated at (...) the contact interface of layer and half-space. The displacement of the mountains has been derived by solving energy equations analytically. The influence of rigid and soft mountain surfaces on the phase velocity of shear waves has been demonstrated graphically. (shrink)

The action for a massive particle in special relativity can be expressed as the invariant proper length between the end points. In principle, one should be able to construct the quantum theory for such a system by the path integral approach using this action. On the other hand, it is well known that the dynamics of a free, relativistic, spinless massive particle is best described by a scalar field which is equivalent to an infinite number of harmonic oscillators. We clarify (...) the connection between these two—apparently dissimilar—approaches by obtaining the Green function for the system of oscillators from that of the relativistic particle. This is achieved through defining the path integral for a relativistic particle rigorously by two separate approaches. This analysis also shows a connection between square root Lagrangians and the system of harmonic oscillators which is likely to be of value in more general context. (shrink)

This biography is a short yet comprehensive overview of the life of Meghnad Saha, the mastermind behind the frequently used Saha equations and a strong contributor to the foundation of science in India. The author explores the lesser known details behind the man who played a major role in building scientific institutions in India, developed the breakthrough theory of thermal ionization, and whose fervor about India's rapid progress in science and technology, along with concern for uplifting his countrymen and optimizing (...) resources, led him to eventually enter politics and identify the mismanagement of many programs of national importance to Parliament. This book is free of most academic technicalities, so that the reader with general scientific knowledge can read and understand it easily. One interested only in Saha's contribution to physics can pick up just that part and read it. Conversely, the average reader may skip the technical chapters, and read the book without loss of continuity or generality to still get a coherent picture. This work touches on all aspects of Saha's multidimensional personality, which overflows in the pages of his periodical, Science and Culture,as well as his many speeches, debates and discussions in Parliament, all of which is appropriately conveyed in this book.

Examines extremity as a political and cultural phenomenon in the late 20th and early 21st century. It argues that we can discern a ‘continuum of extremes/extremity’ on which we may locate practices as diverse as Abu Ghraib, extreme sports, biomedical TV series and horror films.

This book examines the idea of cosmopolitanism, its reconceptualisations and critiques. It explores the specific institutional and philosophical challenges in constructing a cosmopolitan political community and critically engages with assumptions about the nature and direction of global politics. The volume presents a post-colonial critique of 'Western' cosmopolitanism and suggests alternative frameworks.

Obtaining ‘informed consent’ from every individual participant involved in health research is a mandatory ethical practice. Informed consent is a process whereby potential participants are genuinely informed about their role, risk and rights before they are enrolled in the study. Thus, ethics committees in most countries require ‘informed consent form’ as part of an ethics application which is reviewed before granting research ethics approval. Despite a significant increase in health research activity in low-and middle-income countries in recent years, only limited (...) work has been done to address ethical concerns. Most ethics committees in LMICs lack the authority and/or the capacity to monitor research in the field. This is important since not all research, particularly in LMICs region, complies with ethical principles, sometimes this is inadvertently or due to a lack of awareness of their importance in assuring proper research governance. With several examples from Nepal, this paper reflects on the steps required to obtain informed consents and highlights some of the major challenges and barriers to seeking informed consent from research participants. At the end of this paper, we also offer some recommendations around how can we can promote and implement optimal informed consent taking process. We believe that paper is useful for researchers and members of ethical review boards in highlighting key issues around informed consent. (shrink)

In this paper we take a fresh look at the information retrieval problem of balancing recall with precision in electronic document extraction. We examine the IR constructs of uncertainty, context and relevance, proposing a new process model for context learning, and introducing a new IT artifact designed to support user driven learning by leveraging explicit knowledge to discover implicit knowledge within a corpus of documents. The IT artifact is a prototype designed to present a small set of extracted documents from (...) a targeted corpus based upon user inputted criteria. The prototype provides the user with the opportunity to balance exploration and exploitation, via iterative relevance feedback to address the problem of imprecision resulting from uncertainty. We model the problem as an exploration–exploitation dilemma and apply it to a specific case of IR called eDiscovery. We conduct a series of behavioral experiments to evaluate the model and the artifact. Our initial findings indicate that the proposed model and the artifact improve performance in the IR result.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.
