There seems to exist a dilemma in the literature as to the correct relativistic formula for the Sagnac phase-shift. The paper addresses this issue in the light of a novel, kinematically equivalent linear Sagnac-type thought experiment, which provides a vantage point from which the effect of rotation in the usual Sagnac effect can be analyzed. The question is shown to be related to the so-called rotating disc problem known as the Ehrenfest paradox. The relativistic formula for the Sagnac phase-shift seems (...) to depend on the way the paradox is resolved. Kinematic resolution of the Ehrenfest paradox proposed by some authors predicts the usually quoted formula for the Sagnac delay but the resolution itself is shown to be based upon some implicit assumptions regarding the behaviour of solid bodies under acceleration. In order to have a greater insight into the problem, a second version of the thought experiment involving linear motion of a “special type” of a non-rigid frame of reference is discussed. It is shown by analogy that the usually quoted special relativistic formula for the Sagnac delay follows, provided the material of the disc matches the “special type.”. (shrink)

BACKGROUND: Health-based journal clubs have been in place for over 100 years. Participants meet regularly to critique research articles, to improve their understanding of research design, statistics and critical appraisal. However, there is no standard process of conducting an effective journal club. We conducted a systematic literature review to identify core processes of a successful health journal club. METHOD: We searched a range of library databases using established keywords. All research designs were initially considered to establish the body of evidence. (...) Experimental or comparative papers were then critically appraised for methodological quality and information was extracted on effective journal club processes. RESULTS: We identified 101 articles, of which 21 comprised the body of evidence. Of these, 12 described journal club effectiveness. Methodological quality was moderate. The papers described many processes of effective journal clubs. Over 80% papers reported that journal club intervention was effective in improving knowledge and critical appraisal skills. Few papers reported on the psychometric properties of their outcome instruments. No paper reported on the translation of evidence from journal club into clinical practice. CONCLUSION: Characteristics of successful journal clubs included regular and anticipated meetings, mandatory attendance, clear long- and short-term purpose, appropriate meeting timing and incentives, a trained journal club leader to choose papers and lead discussion, circulating papers prior to the meeting, using the internet for wider dissemination and data storage, using established critical appraisal processes and summarizing journal club findings.

This article addresses this need and examines the academic literature on Corporate Social Responsibility and Performance using a paradigmatic and methodological lens. The objective of this article is fourfold. First, it examines the status of CSR research from its beginning especially after 1970 to year 2008 in leading academic journals and reports (...) to assess the focus areas of research on CSR so far. Second, it analyzes the research paradigms adopted in these research articles using the Operations Research Paradigm framework. Third, it compares and contrasts various kinds of research articles, methodologies, and research designs used in various researches in literature. Finally, it uncovers the implications of this study and directions for future research. (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)

Felicitas Goodman (1990) observed that naive participants experienced unique trance states, characterized by specific visionary content, when they assumed particular postures and listened to monotonous rattling. Students (n = 284), enrolled in various sections of the course Introduction to Psychology, experienced one of four conditions with their eyes closed: Sitting Quietly with and without Drumming, Standing (Feather Serpent) Posture plus Drumming with and without Suggested Experiences. Participants completed the Phenomenology of Consciousness Inventory (Pekala 1982, 1991c) and wrote narratives following their (...) respective stimulus conditions. Participants reported less imagery, joy, and absorption, but more internal dialogue, self‐awareness, and muscular tension in the posture, compared to the sitting quietly, conditions. Goodman's results of specific posture (content‐related) effects with naive participants were not replicated. (shrink)

We propose a novel edge detector in the presence of Gaussian noise with the use of proximal support vector machine (PSVM). The edges of a noisy image are detected using a two-stage architecture: smoothing of image is first performed using regularized anisotropic diffusion, followed by the classification using PSVM, termed as regularized anisotropic diffusion-based PSVM (RAD-PSVM) method. In this process, a feature vector is formed for a pixel using the denoised coefficient’s class and the local orientations to detect edges in (...) all possible directions in images. From the experiments, conducted on both synthetic and benchmark images, it is observed that our RAD-PSVM approach outperforms the other state-of-the-art edge detection approaches, both qualitatively and quantitatively.

This paper outlines some flaws of the faddist social forestry movement that is currently sweeping Canada's volunteer NGOs. Typically, these include: Canadian NGOs' ignorance of tropical ecology; their inability to adequately communicate with the Third World clientel because of the socio-cultural barriers; a propensity to undertake numerous development projects and thus seek to bloat their organizations so as to claim federal government grants; and most of all, complaints of alleged racism against NGOs by Canada's ethnic minorities who are kept out (...) of the development field. Impacts on the Third World development of each of these flaws are briefly noted. The paper concludes by offering some recommendations for improving Canadian volunteer NGOs' performance in social forestry in the Third World. (shrink)

Post-globalization trends have left many people with a sense of insecurity—on both the economic and the employment fronts. Business re-engineering, downsizing, lay-offs, excessive consumerism and greed have altered the rules of the business game. Skewed attention to mere economic criteria in many business organizations, even at the cost of societal and environmental factors, is leading to a sense of hollowness, ‘something missing’, in the organization and its employees. People are making every attempt to discover this ‘missing component’ in their lives, (...) with particular reference to their work lives. This ‘missing component’ is referred to as ‘spirit at work’ in management literature. Bringing in spirit at work has become a matter of priority for many business organizations, in their drives for sustained success. Spirit at work is about care, compassion, integrity, and about attempting to live one’s values at the workplace. It is about employees who are passionate and energized by their work, who find meaning and purpose and pursue excellence in their work, and who feel that they can express their complete selves at work. It is about individuals and organizations that see work as an opportunity to grow and to contribute to society in a meaningful way. Spirit at work can be better understood by gaining clarity about the key aspects that constitute this concept. This article reviews the extant litera-ture on spirit at work, highlights the key dimensions of spirit at work, and elaborates on each of them. A number of Indian scholars like S.K. Chakraborty, Subhash Sharma, M.B. Athreya, Panduranga Bhatta and others have proposed an Indian perspective of spirit at work and have elaborated on it since a decade and a half. This article extends the Indian perspective further, based on Indian psychophilosophy, and establishes its comprehensive and inclusive nature that enables incorporation of most of the key dimensions of spirit at work as identified in literature.

Two algebraic structures, the contrapositionally complemented Heyting algebra (ccHa) and the contrapositionally |$\vee $| complemented Heyting algebra (c|$\vee $|cHa), are studied. The salient feature of these algebras is that there are two negations, one intuitionistic and another minimal in nature, along with a condition connecting the two operators. Properties of these algebras are discussed, examples are given and comparisons are made with relevant algebras. Intuitionistic Logic with Minimal Negation (ILM) corresponding to ccHas and its extension |${\textrm {ILM}}$|-|${\vee }$| for c|$\vee (...) $|cHas are then investigated. Besides its relations with intuitionistic and minimal logics, ILM is observed to be related to Peirce’s logic and Vakarelov’s logic MIN. With a focus on properties of the two negations, relational semantics for ILM and |${\textrm {ILM}}$|-|${\vee }$| are obtained with respect to four classes of frames, and inter-translations between the classes preserving truth and validity are provided. ILM and |${\textrm {ILM}}$|-|${\vee }$| are shown to have the finite model property with respect to these classes of frames and proved to be decidable. Extracting features of the two negations in the algebras, a further investigation is made, following logical studies of negations that define the operators independently of the binary operator of implication. Using Dunn’s logical framework for the purpose, two logics |$K_{im}$| and |$K_{im-{\vee }}$| are discussed, where the language does not include implication. The |$K_{im}$|-algebras are reducts of ccHas and are different from relevant algebraic structures having two negations. The negations in the |$K_{im}$|-algebras and |$K_{im-{\vee }}$|-algebras are shown to occupy distinct positions in an enhanced form of Dunn’s kite of negations. Relational semantics for |$K_{im}$| and |$K_{im-{\vee }}$| is provided by a class of frames that are based on Dunn’s compatibility frames. It is observed that this class coincides with one of the four classes giving the relational semantics for ILM and |${\textrm {ILM}}$|-|${\vee }$|⁠. (shrink)

: Classical Sāmkhya, as represented by Īśvarakrsna's Sāmkhya-kārikā, is well known for its attempt to prove not only the reality but the plurality of selves (purusa-bahutva). The Sāmkhya argument, since it proceeds from the reality of the manyness of the bodies as its basic premise, approximates, even if not in every detail, the 'argument from analogy' in its traditional form (which the essay tries to explicate). One distinguished modern interpreter, K. C. Bhattacharyya, however, not satisfied with this account, attempts to (...) interpret and expound Sāmkhya pluralism in terms of a radically different strategy consisting of showing that the self is known in buddhi in its pure asmita function as an infinite I and so as necessarily involving all Is or selves. This solution, which in the process offers reflections on such issues as infinity, universals, the role of 'I', the individuality (of self ), et cetera, is examined and criticized at length with respect to some of its basic assumptions, with a brief focus on the idea of 'self-consciousness', which according to some (Western) philosophers presupposes 'other'-consciousness and which in certain respects seems to inform Bhattacharyya's thoughts on the main issue.

The role of Indian ethos in management practices is explored by several management scholars and practitioners. Professor Sitangshu Kumar Chakraborty (popularly known as Professor S. K. Chakraborty, hereinafter referred to as SKC in this article) is one of the pioneering scholars of human value-oriented management practices and has made significant contributions in linking the management knowledge and practices to classical Indian ethos and Vedantic wisdom. In today’s technologically advanced and economically fast-paced world, there is a rising concern about falling (...) human values in work and in personal life, which must be addressed to understand the deeper meaning of work and a higher purpose in life. SKC’s innovative approaches to human values in management education for practising managers are quite significant in this regard. This article is a sincere attempt to explore and synthesize the contributions of SKC to the human value-oriented management that evolved around the fundamental pillars of classical Indian ethos and Vedantic wisdom and the implication of those values for today’s managers to realign their managerial practices. This article is based on a bibliometric analysis of published articles drawn from secondary sources and is a tribute to the life and legacy of SKC on human value-based management. (shrink)

The present work, "Indian Philosophers of the Recent Past" , reflects and deliberates over recent Indian scholarship in philosophy. It is to get the present and future generations of philosopher-scholars acquainted with the rich Indian philosophical heritage. This is going to deepen our insights into the nature of philosophical consciousness and into the act of philosophizing. It makes an attempt to analyse the philosophies of outstanding philosophers such as K.C. Bhattacharyya, S. Radhakrishnan, R.D. Ranade, A.C. Mukerji, T.R.V. Murti, N.K. Devraja, (...) J.L. Mehta, J.N. Mohanty, Daya Krishna and S.L. Pandey. The post-Independent Indian philosophy is said to have unique tendencies and trends; some of them can be easily identified as existentialist and phenomenological, idealistic, realistic, humanistic, linguistic and analytico-philosophical comparative philosophy and Indian defence of metaphysics. The volume is unique in its conceptual clarity, lucid expression, systematic presentation and critical exposition of the subject matter. It is undoubtedly a valuable contribution for the seekers of Indian philosophical system which should evoke keen interest among scholars and students of philosophy. (shrink)

Introduction of deep neural networks to the machine translation research ameliorated conventional machine translation systems in multiple ways, specifically in terms of translation quality. The ability of deep neural networks to learn a sensible representation of words is one of the major reasons for this improvement. Despite machine translation using deep neural architecture is showing state-of-the-art results in translating European languages, we cannot directly apply these algorithms in Indian languages mainly because of two reasons: unavailability of the good corpus and (...) Indian languages are morphologically rich. In this paper, we propose a neural machine translation (NMT) system for four language pairs: English–Malayalam, English–Hindi, English–Tamil, and English–Punjabi. We also collected sentences from different sources and cleaned them to make four parallel corpora for each of the language pairs, and then used them to model the translation system. The encoder network in the NMT architecture was designed with long short-term memory (LSTM) networks and bi-directional recurrent neural networks (Bi-RNN). Evaluation of the obtained models was performed both automatically and manually. For automatic evaluation, the bilingual evaluation understudy (BLEU) score was used, and for manual evaluation, three metrics such as adequacy, fluency, and overall ranking were used. Analysis of the results showed the presence of lengthy sentences in English–Malayalam, and the English–Hindi corpus affected the translation. Attention mechanism was employed with a view to addressing the problem of translating lengthy sentences (sentences contain more than 50 words), and the system was able to perceive long-term contexts in the sentences.

Increasingly, national governments across the globe are prioritizing investments in neuroscience. Currently, seven active or in-development national-level brain research initiatives exist, spanning four continents. Engaging with the underlying values and ethical concerns that drive brain research across cultural and continental divides is critical to future research. Culture influences what kinds of science are supported and where science can be conducted through ethical frameworks and evaluations of risk. Neuroscientists and philosophers alike have found themselves together encountering perennial questions; these questions are (...) engaged by the field of neuroethics, related to the nature of understanding the self and identity, the existence and meaning of free will, defining the role of reason in human behavior, and more. With this Perspective article, we aim to prioritize and advance to the foreground a list of neuroethics questions for neuroscientists operating in the context of these international brain initiatives.

This paper explores one aspect of the political in the early Hegel, that of criminal action and its relationship to the concept of recognition in the System of Ethical Life. While it is clear that in this work Hegel thinks that criminal action plays an important role in the transformation of simple ethical communities, it is not clear that, for Hegel, the formal character of crime in the struggle for recognition is anything but negative. I attempt to show how this (...) role for crime leads Hegel to a legalistic conception of Right that has no solid connection with recognition as a social force. (shrink)

The unknown nature of tomorrow’s research makes informed consent in biobank research a challenge. Whether the consent given by biobank participants is ‘broad’ or ‘narrow’, the ever present question remains the same: are new activities covered by the original consent? In this article, we focus on the meaning of, and the relation between, broad consent and re-consent in biobank research. We argue that broad consent should be understood as consenting to a framework—a framework which covers aims, core conditions for acceptable (...) use, governance and how these affect participants. Changes that alter the framework in a fundamental way call for re-consent. Three biobank cases of current international interest are used to debate when re-consent is an ethical necessity: whole-genome sequencing, data sharing and commercial utilization. These reflections give us a more nuanced view on what consent is for. We claim that the introduction of broad consents in biobank research has not represented a betrayal of individual participant interests, as some critics have asserted. Broad consents combined with the possible use of re-consent are in certain settings not inferior, but rather ethically superior to narrow consents. In population-based research biobanks, they allow for a reconciliation between individual interest and public matters in society at large. (shrink)

Moral licensing theory suggests that observers may liberate actors to behave in morally questionable ways due to the actors’ history of moral behaviors. Drawing on this view, a scenario experiment with a 2 (high vs. low ethical)×2 (internal vs. external motivation) between-subject design (N = 455) was conducted in the current study. We examined whether prior ethical leader behaviors cause subordinates to license subsequent abusive supervision, as well as the moderating role of behavior motivation on such effects. The results showed (...) that when supervisors demonstrated prior ethical behaviors, subordinates, as victims, liberated them to act in abusive ways. Specifically, subordinates showed high levels of tolerance and low levels of condemnation towards abusive supervision and seldom experienced emotional responses to supervisors’ abusive behaviors. Moreover, subordinates tended to attribute abusive supervision, viewed as a kind of mistreatment without an immediate intent to cause harm, to characteristics of the victims and of the organization rather than of the supervisors per se. When supervisors behaved morally out of internal rather than external motivations, the aforementioned licensing effects were stronger. (shrink)
