This article attempts to investigate the three strands of citizenship, nationalism and education and their interconnectedness in India after independence. It seeks to address questions like how has the post-colonial state in India visualized its models of citizenship through its education policies and programmes and what has become of their fate? In what ways the changing nature of public versus private education has shaped contested models of citizenship? What challenges are thrown at the models of citizenship that the Indian state (...) has tried to posit through education? It is argued that the journey of citizenship in post-independent India is that of contradictory pulls around key strands of ethno-cultural nationalism and civic nationalism and around an economically productive nation versus an economic consumer nation. The article will look at some of the key policy shifts and operational models and attempt to locate the dynamic behind those shifts. (shrink)

Recent scandals at Enron, WorldCom and Global Crossing have put the ethical spotlight on corporate malfeasance as never before. However, these are the situations in which management knew that they made the wrong choice. As professor Joseph Badaracco of Harvard Business School points out, the real ethical dilemmas arise when people must choose between right and right — where both choices can be justified, yet one must be chosen over the other. Whether or not to reprice stock options represents one (...) such ethical dilemma. Repricing can help exodus of talented employees and motivate them to improve firm performance. However, it alienates shareholders and other workers of the company who are left unprotected from the adverse economic consequences of a stock price decline.In this paper we examine the ethics and the economics of stock option repricing. We find that repricing runs counter to two key tenets of business ethics — distributive justice and ordinary decency. To examine the economics of repricing, we draw upon agency theory to identify situations where repricing has the potential to benefit shareholders. However, a survey of empirical research reveals that these benefits do not translate into reality. Repricing does not improve employee retention or firm performance. In addition, managers benefit by opportunistically timing the repricing. Due to weaknesses in corporate governance such as lack of independence and conflicts of interest, the current repricing practice seems to be at odds with the objective of shareholder wealth maximization, and at a more fundamental level, a violation of board's fiduciary duty to shareholders. We offer suggestions that mitigate the ethically undesirable effects of repricing in the wider context of prevailing corporate governance and regulatory environment. We believe that these suggestions, if properly implemented, can transform repricing from a greed-inspired evil to a valuable compensation tool to retain employees, boost their morale, and enhance stockholder wealth.

Building on a base of simple economic theory and elementary linear algebra and calculus, this broad treatment of static and dynamic optimization methods discusses the importance of shadow prices and functions defined by solutions of optimization problems.

Agrarian environments have to be comprehended as being part of a biophysical and social environment that includes the urban and the nonurban, the arable and the nonarable, and other areas that are integrally linked to the world of agriculture and environment and their allied socioeconomic relations. This article examines the responses of rice biotechnologists located in selected Indian public agricultural institutes under the aegis of the State Agricultural University and the Indian Council of Agricultural Research on questions such as “How (...) is GM (genetically modified) technology perceived by rice biotechnologists and under what limiting conditions is it being pursued in rice biotechnology research? Is there a consensus among rice biotechnologists over the application of GM technology? What are the complexities of the GM policy? and What are the implications of intellectual property rights on GM-based research and how scientists are responding to such institutional norms?”.

Application of recently developed non-Archimedean algebra to a flat and finite universe of total mass M 0 and radius R 0 is described. In this universe, mass m of a body and distance R between two points are bounded from above, i.e., 0≤m≤M 0, 0≤R≤R 0. The universe is characterized by an event horizon at R 0 (there is nothing beyond it, not even space). The radial distance metric is compressed toward horizon, which is shown to cause the phenomenon of (...) red shift. The corresponding modified Minkowski's metric and Lorentz transforms are obtained. Applications to Newtonian gravity shows a weakening at large scales (R→R 0) and a regular behavior as R→0. (shrink)

The study of consciousness is poised today at interesting crossroads. There has been a surge of research into various neurobiological underpinnings of consciousness in the past decade. The present article looks at the theories regarding this complex phenomenon, especially the ones that neurobiology, cognitive neuroscience and cognitive psychology have to offer. We will first discuss the origin and etymology of word consciousness and its usage. Neurobiological correlates of consciousness are discussed with structures like the ascending reticular activating system, the amygdala, (...) the cerebellum, the thalamus, the frontoparietal circuits, the prefrontal cortex and the precuneus. The cellular and microlevel theories of consciousness and cerebral activity at the neuronal level contributing to consciousness are highlighted, along with the various theories posited in this area. The role of neuronal assemblies and circuits along with firing patterns and their ramifications for the understanding of consciousness are discussed. A section on the role of anaesthesia and its links to consciousness is presented, along with details of split-brain studies in consciousness and altered states of awareness, including the vegetative states. The article finally discusses the progress cognitive psychology has made in identifying and theorising various perspectives of consciousness, perceptual awareness and conscious processing. Both recent and past researches are highlighted. The importance and salient features of each theory are discussed along with the pitfalls, if present. A need for integration of various theories to understand consciousness from a holistic perspective is stressed, to enable one to reach a theory that explains the ultimate neurobiology of consciousness.

The study of consciousness has today moved beyond neurobiology and cognitive models. In the past few years, there has been a surge of research into various newer areas. The present article looks at the non-neurobiological and non-cognitive theories regarding this complex phenomenon, especially ones that self-psychology, self-theory, artificial intelligence, quantum physics, visual cognitive science and philosophy have to offer. Self-psychology has proposed the need to understand the self and its development, and the ramifications of the self for morality and empathy, (...) which will help us understand consciousness better. There have been inroads made from the fields of computer science, machine technology and artificial intelligence, including robotics, into understanding the consciousness of these machines and their implications for human consciousness. These areas are explored. Visual cortex and emotional theories along with their implications are discussed. The phylogeny and evolution of the phenomenon of consciousness is also highlighted, with theories on the emergence of consciousness in fetal and neonatal life. Quantum physics and its insights into the mind, along with the implications of consciousness and physics and their interface are debated. The role of neurophilosophy to understand human consciousness, the functions of such a concept, embodiment, the dark side of consciousness, future research needs and limitations of a scientific theory of consciousness complete the review. The importance and salient features of each theory are discussed along with certain pitfalls, if present. A need for the integration of various theories to understand consciousness from a holistic perspective is stressed. (shrink)

Attention deficit hyperactivity disorder is a developmental disorder with an age onset prior to 7 years. Children with ADHD have significantly lower ability to focus and sustain attention and also score higher on impulsivity and hyperactivity. Stimulants, such as methylphenidate, have remained the mainstay of ADHD treatment for decades with evidence supporting their use. However, recent years have seen emergence of newer drugs and drug delivery systems, like osmotic release oral systems and transdermal patches, to mention a few. The use (...) of nonstimulant drugs like atomoxetine and various other drugs, such as a-agonists, and a few antidepressants, being used in an off-label manner, have added to the pharmacotherapy of ADHD. This review discusses current trends in drug therapy of ADHD and highlights the promise pharmacogenomics may hold in the future. (shrink)

This paper aims at taking a fresh look at Freudian psychoanalytical theory from a modern perspective. Freudian psychology is a science based on the unconscious and the conscious . Various aspects of Freudian thinking are examined from a modern perspective and the relevance of the psychoanalytical theory of consciousness is projected. Do psychoanalysis and the unconsciousness have something to teach us about consciousness? Approaching Freud from a historical, psychoanalytical, anthropological and sociological perspective, we need to look at how Freudian theory (...) may contribute to a better understanding of consciousness. We also need to look at psychoanalytical psychotherapy and its contribution to a better understanding of body-mind dualism and consciousness as a whole. Ego psychology is considered in the present day context and it is synthesized with various psychological studies to give us a better understanding of consciousness. (shrink)

The psychopharmacology of alcohol dependence is today poised at interesting crossroads. Three major drugs Naltrexone, Disulfiram and Acamprosate have been tried and tested in various trials and have many meta-analyses each to support them. While Naltrexone may reduce craving, Acamprosate scores on cost effectiveness worldwide with Disulfiram being an alcohol deterrent drug. Studies support, refute and criticize the use of each of these drugs. Combining one or more of them is also a trend seen. The most important factor in efficacy (...) has been the combination of psychosocial treatment with medication. Studies from the early 1970s to date have been reviewed and the findings presented in a manner useful for the busy clinician to judge the best pharmacological option in the management of alcohol dependence. The role of depot disulfiram, naltrexone, and medications like Topiramate and SSRIs under research for alcohol dependence, are also addressed. (shrink)

In this article, epoch-based dynamic features such as sequence of epoch interval values and epoch strength values are explored to classify infant cries. Epoch is the instant of significant excitation of the vocal tract system during the production of speech. For voiced speech, the most significant excitation takes place around the instant of glottal closure. The different types of infant cries considered in this work are hunger, pain, and wet diaper. In this work, epoch strength and epoch interval features are (...) used to represent infant cry-specific information from the acoustic signal. In this study, the proposed features such as epoch interval and epoch strength values are determined using zero-frequency filter-based method. Gaussian mixture models are used to classify the above-mentioned cries from the features proposed in this work. GMMs are developed separately for each of the cries using the proposed features. The infant cry database collected under a telemedicine project at the Indian Institute of Technology Kharagpur has been used for this study. In the first step, infant cry recognition accuracy is investigated separately using epoch interval and epoch strength features. To enhance recognition performance, GMMs developed using various features are combined through score level fusion techniques. The recognition performance using a combination of evidence is found to be superior over individual systems. (shrink)

: The open-ended character of natural languages calls for the hypothesis that humans are endowed with a recursive procedure generating sentences which are hierarchically organized. Structural relations such as c-command, expressed on hierarchical sentential representations, determine all sorts of formal and interpretive properties of sentences. The relevant computational principles are well beyond the reach of conscious introspection, so that studying such properties requires the formulation of precise formal hypotheses, and empirically testing them. This article illustrates all these aspects of linguistic (...) research through the discussion of non-coreference effects. The article argues in favor of the formal linguistic approach based on hierarchical structures, and against alternatives based on vague notions of “analogical generalization”, and/or exploiting mere linear order. In the final part, the issue of cross-linguistic invariance and variation of non-coreference effects is addressed. Keywords: Linguistic Knowledge; Morphosyntactic Properties; Unconscious Computations; Coreference; Linguistic Representations Conoscenza linguistica e computazioni inconsce Riassunto: Il carattere aperto del linguaggio naturale avvalora l’ipotesi che gli esseri umani siano dotati di una procedura ricorsiva che genera frasi gerarchicamente organizzate. Relazioni strutturali come il c-comando, espresse su rappresentazioni frasali gerarchiche, determinano tutte le proprietà formali e interpretative delle frasi. I principi computazionali rilevanti sono totalmente al di fuori della portata della coscienza introspettiva e così lo studio di tali proprietà richiede la formulazione di precise ipotesi formali e la loro verifica sperimentale. Questo articolo illustra tutti questi aspetti della ricerca linguistica, esaminando gli effetti di non-coreferenza. Si argomenta in favore dell’approccio linguistico formale basato su strutture gerarchiche e contro alternative basate su vaghe nozioni di “generalizzazione analogica” e/o che impiegano il semplice ordine lineare. Nella parte finale si affronta il tema dell’invarianza e della variazione cross-linguistica degli effetti di non-coreferenza. Parole chiave: Conoscenza linguistica; Proprietà morfosintattiche; Computazioni inconsce; Coreferenzialità; Rappresentazioni linguistiche. (shrink)

In 1977 a seminal paper was published by Avinash Dixit and Joseph Stiglitz that revolutionized the modeling of imperfectly competitive markets. It launched what might be called the second monopolistic competition revolution, which has been far more successful than the first one, initiated by Edward Chamberlin and Joan Robinson in the 1930s. In this 2003 collection of essays experts in the fields of macroeconomics, international trade theory, economic geography, and international growth theory address the question of why the second (...) revolution was so successful. They also highlight what is missing, and look forward to the next step in the modeling of imperfectly competitive markets. The text includes a comprehensive survey of both monopolistic competition revolutions, and previously unpublished working papers by Dixit and Stiglitz that led to their famous 1977 paper. With contributions from Dixit, Ethier, Neary and Stiglitz amongst others, this collection will excite interest amongst researchers, advanced students and economists. (shrink)
