We describe a prey–predator system incorporating constant prey refuge through provision of alternative food to predators. The proposed model deals with a problem of non-selective harvesting of a prey–predator system in which both the prey and the predator species obey logistic law of growth. The long-run sustainability of an exploited system is discussed through provision of alternative food to predators. We have analyzed the variability of the system in presence of constant prey refuge and examined the stabilizing effect on predator–prey (...) system. The steady states of the system are derived and dynamical behavior of the system is extensively analyzed around steady states. The optimal harvesting policy is formulated and solved with the help of Pontryagin’s maximal principle. Our objective is to maximize the monetary social benefit through protecting the predator species from extinction, keeping the ecological balance. Results finally illustrated with the help of numerical examples. (shrink)

The 'wall' that differentiates two different kinds of attitudes of the same person at different points of time denotes, as the author envisages, Conscious Attitudinal Infringement Area (CAIA), where moral dilemmas take birth to bridge the two different kinds of attitudes to give way to attitudinal interrelatedness. In order to 'reinforce' CAIA to narrow the gap between personal behaviour and public behaviour, lead a moral life and behave ethically in public, there has to be harmony between the inner life of (...) thoughts, feelings and emotions, and the circumstances and events in the person's outer environment. After discussing the corporate scenario in India in brief, the author has put forward a model called Action By Objectives (ABO) as the basis of the harmonization approach. Drawing inspiration from the ethical aspects of Buddhism, Sufism, Sikhism and Vedanta in this context, he suggests an abhyasa yoga (perfection through disciplined practice) menu for refining samskaras (inner predispositions) and reaching the ultimate level of positive, inspiring leadership.

Literary renditions of cities have always gravitated towards the spatial imagination and its ethical counterpart outside the textual space. This paper explores the multicultural geography of the North Indian city Allahabad observed through Neelum Saran Gour’s postcolonial narratives Allahabad Aria and Invisible Ink, projecting the narrative alignment of spatial aesthetics and cultural ethics. Interrogating the spatial dimensions of a “narrative world” within narrative theory and its interdisciplinary crossover with cultural geography, the article seeks to examine Gour’s literary city not simply (...) as an objective homogeneous representation, but as a “kshetra” of spatio-cultural cosmos of lived traditions, memories, experiences and collective attitudes of its people, in the context of E. V. Ramakrishnan’s theoretical reflections. The article proposes new possibilities of adapting the Indian concept “kshetra” to spatial literary studies; its aim is also to suggest a new source of knowledge about the city of Allahabad through a community introspection of “doing culture” in the texts, bringing into view people’s shared experiences, beliefs, religious practices and traditions as offshoots of the postcolonial ethos. The article aims to re-contextualize the city’s longstanding multicultural ethics in the contemporary times of crisis, which may affect a shift in the city’s relevance: from regional concern to large-scale significance within ethnically diverse South Asian countries and beyond.

This compilation analyzes the differences between the concepts of ‘social responsibility’ and ‘business ethics’, which are often erroneously interpreted to be the same. It explains that social responsibility is a characteristic but just one of the many aspects of the much wider concept of business ethics. The collection includes contributions from experts from diverse fields such as industry, academia, and non-governmental organizations, who present the theoretical underpinning of the concepts, along with real-life case studies dealing with the varied, hands-on experiences (...) of leaders from different industries.

This article examines the relationship between gender, nations and nationalisms vis-a-vis the Indian state's nationalist identity and perceptions of security. It explores how the postcolonial Indian state's project of nation-building — reflective of a western secular-modern identity and a Hindutva-dominated identity — incorporates gender, with continuities and discontinuities, to articulate divergent forms of nationalist/communalist identities, `cartographic anxieties' and nuclear securities. The article contends that with the recent rise of the Hindu-Right BJP, guided by Hindutva ideology, the nature of representing the (...) Indian nation, its women and securities has changed from a geopolitical to a cultural perception — thereby necessitating a rereading of the Indian nation, nationalism, gender and its perceptions of security.

In this article, I cast doubt on an apparent truism, namely, that if evidence is available for gathering and use at a negligible cost, then it’s always instrumentally rational for us to gather that evidence and use it for making decisions. Call this ‘value of information’ (VOI). I show that VOI conflicts with two other plausible theses. The first is the view that an agent’s evidence can entail non-trivial propositions about the external world. The second is the view that epistemic (...) rationality requires us to update our credences by conditionalization. These two theses, given some plausible assumptions, make room for rationally biased inquiries where VOI fails. I go on to argue that this is bad news for defenders of VOI. (shrink)

Cultural diversity is an inescapable reality and a concern in many businesses where it can often raise ethical questions and dilemmas. This paper aims to offer suggestions to certain problems facing managers in dealing with cultural diversity through the inspiration of Thomas Aquinas. Although he may be perceived as a voice from the distant past, we can still find in his writings helpful and original ideas and criteria. He welcomes cultural differences as a part of the perfection of the universe. (...) His systemic approach leads one to place the problem in its proper context, and to reflect on it from the perspective of virtue ethics, with a central role for practical wisdom and giving primacy to neighborly love and natural moral law. Rather than a set of rigid standards with no consideration of diversity Aquinas focuses on the common human ground, which allows for the indispensable dialogue between different positions. When dealing with practical questions, the problem is one of finding the right balance between general principle and cultural specifics, tolerance, and dialogue, always guided by practical wisdom. In this way, Aquinas’ approach is neither rigid ethical universalism with no consideration for diversity nor moral relativism with no place for any transcultural and absolute morals. (shrink)

Echoing bell hooks’s discussions on “black rage,” this article explores the politics of “Dalit rage” by juxtaposing some instances of projections of Dalits as an “angry,” “illiberal,” and “intolerant” constituency with examples of anger from Dalit literature. While these projections in “mainstream” media and caste Hindu–dominated civil society narratives often represent them as engulfed in the emotive states marked by anger, intolerance, and impatience, the instances from Dalit literature archive a “Dalit rage” that demands to be dissociated from the Nietzschean (...) category of ressentiment. Through B. R. Ambedkar’s readings of Nietzsche in Philosophy of Hinduism and Nietzsche’s readings of Manu’s Manavadharmashastra in Twilight of the Idols, this article draws a fine line of differentiation between Nietzsche’s contempt for ressentiment and Manu’s disdain for anger. “Dalit rage” occupies a distinctly different thymotic space and articulates a Dalit predicament that exploits rage as a marker of protest, resistance, and caste-ridden social conflicts. This article shows why we cannot bracket Nietzsche’s contempt for ressentiment with Manu’s demands of the sudras (and, in extension, other “lower castes”/Dalits) to be “meek” by exploring Manu’s perpetuation and legitimization of the varna order through a “morality of breeding” and Nietzsche’s more wholesale rejection of morality as he deems it a pia fraus (moral fraud). Thus this “Dalit rage” offers us a repository of the limits of a liberal democracy and enables an Ambedkarite reading of Nietzsche whose project of constructing ubermensch is markedly different from Manu’s “morality of taming” through a “morality of breeding.”.

An important question in epistemology is whether the KK principle is true, i.e., whether an agent who knows that p is also thereby in a position to know that she knows that p. We explain how a “transparency” account of self-knowledge, which maintains that we learn about our attitudes towards a proposition by reflecting not on ourselves but rather on that very proposition, supports an affirmative answer. In particular, we show that such an account allows us to reconcile a version (...) of the KK principle with an “externalist” or “reliabilist” conception of knowledge commonly thought to make that principle particularly problematic.

How do senior business executives rank their preferences for various ethical principles? And how strongly do the executives believe in these principles? Also, how do these preference rankings relate to the way the executives see the future (wherein business decisions play out)? Research on these questions may provide us with an appreciation of the complexities of ethical behavior in management beyond the traditional issues concerning ethical decision-making in business. Based on a survey of 585 vice presidents of U.S. businesses it (...) was found that: (1) there is a distinct set of principles of ethical conduct that is considered favorable as opposed to another set considered unfavorable among a comprehensive list of 14 ethical principles; (2) the executives believed overwhelmingly that their own individual ethical preferences are better than those of other executives; (3) the strength of their preferences for ethical principles is associated with whether the executives are relatively near-future oriented or more distant-future oriented; and (4), there are very few significant differences in terms of gender, age, education level, private/public education, prestigious/other schools, business/non-business academic backgrounds, and length of job experience. Implications of these findings are discussed. (shrink)

This paper is about a tension between two theses. The first is Value of Evidence: roughly, the thesis that it is always rational for an agent to gather and use cost‐free evidence for making decisions. The second is Rationality of Imprecision: the thesis that an agent can be rationally required to adopt doxastic states that are imprecise, i.e., not representable by a single credence function. While others have noticed this tension, I offer a new diagnosis of it. I show that (...) it arises when an agent with an imprecise doxastic state engages in an unreflective inquiry, an inquiry where they revise their beliefs using an updating rule that doesn't satisfy a weak reflection principle. In such an unreflective inquiry, certain synchronic norms of instrumental rationality can make it instrumentally irrational for an agent to gather and use cost‐free evidence. I then go on to propose a diachronic norm of instrumental rationality that preserves Value of Evidence in unreflective inquiries. This, I suggest, may help us reconcile this thesis with Rationality of Imprecision. (shrink)

This essay explores a problem for Nyāya epistemologists. It concerns the notion of pramā. Roughly speaking, a pramā is a conscious mental event of knowledge-acquisition, i.e., a conscious experience or thought in undergoing which an agent learns or comes to know something. Call any event of this sort a knowledge-event. The problem is this. On the one hand, many Naiyāyikas accept what I will call the Nyāya Definition of Knowledge, the view that a conscious experience or thought is a knowledge-event (...) just in case it is true and non-recollective. On the other hand, they are also committed to what I shall call Nyāya Infallibilism, the thesis that every knowledge-event is produced by causes that couldn’t have given rise to an error. These two commitments seem to conflict with each other in cases of epistemic luck, i.e., cases where an agent arrives a true judgement accidentally or as a matter of luck. While the Nyāya Definition of Knowledge seems to predict that these judgements are knowledge-events, Nyāya Infallibilism seems to entail that they aren’t. In this essay, I show that Gaṅgeśa Upādhyāya, the 14th century Naiyāyika, solves this problem by adopting what I call epistemic localism, the view that upstream causal factors play no epistemically significant role in the production of knowledge.

According to Bayesian orthodoxy, an agent should update---or at least should plan to update---her credences by conditionalization. Some have defended this claim by means of a diachronic Dutch book argument. They say: an agent who does not plan to update her credences by conditionalization is vulnerable (by her own lights) to a diachronic Dutch book, i.e., a sequence of bets which, when accepted, guarantee loss of utility. Here, I show that this argument is in tension with evidence externalism, i.e., the (...) view that an agent's evidence can entail non-trivial propositions about the external world. I argue that this tension casts doubt on the idea that diachronic Dutch books can be used to justify or vindicate updating plans. (shrink)

In this paper I evaluate some recent virtue-ethical accounts of right action [Hursthouse 1999; Slote 2001; Swanton 2001]. I argue that all are vulnerable to what I call the insularity objection : evaluating action requires attention to worldly consequences external to the agent, whereas virtue ethics is primarily concerned with evaluating an agent's inner states. More specifically, I argue that insofar as these accounts are successful in meeting the insularity objection they invite the circularity objection : they end up relying (...) upon putatively virtue-ethical considerations that themselves depend on unexplained judgments of rightness. Such accounts thus face a dilemma that is characteristic of virtue-ethical accounts of right action. They avoid the insularity objection only at the cost of inviting the circularity objection: they become intuitively plausible roughly to the extent that they lose their distinctively virtue-ethical character.

Recently, several epistemologists have defended an attractive principle of epistemic rationality, which we shall call Ur-Prior Conditionalization. In this essay, I ask whether we can justify this principle by appealing to the epistemic goal of accuracy. I argue that any such accuracy-based argument will be in tension with Evidence Externalism, i.e., the view that agent's evidence may entail non-trivial propositions about the external world. This is because any such argument will crucially require the assumption that, independently of all empirical evidence, (...) it is rational for an agent to be certain that her evidence will always include truths, and that she will always have perfect introspective access to her own evidence. This assumption is in tension with Evidence Externalism. I go on to suggest that even if we don't accept Evidence Externalism, the prospects for any accuracy-based justification for Ur-Prior Conditionalization are bleak. (shrink)

Este estudo objetiva identificar os saberes específicos para o ensino de Língua Portuguesa de professores sem formação específica. Trata-se de uma pesquisa de abordagem qualitativa e biográfica, sendo de cunho exploratório, realizada a partir das histórias de vida. Utilizamos, para produção dos dados, os Ateliês Biográficos de Projetos proposto por Delory-Momberger. O corpus da pesquisa é composto pelas narrativas biográficas construídas nos encontros do ABP e empregamos a análise de conteúdo como técnica para análise dos dados. Assim, evidenciamos que os (...) professores revelaram saberes e não saberes advindos das relações sociais e de sua formação profissional. Constatamos, ainda, a existência de trajetórias marcadas por histórias de vida diferentes, mas que convergem na docência em Língua Portuguesa ; que estes professores aprendem nos caminhos da docência; que mesmo sem terem a formação específica conseguem ensinar. Dessa forma, percebemos os processos formativos a partir da perspectiva pedagógica presente na prática e da revelação de saberes e não saberes para o ensino de Língua Portuguesa, que contribuem para a construção de aprendizagens da docência.

In the Open darkness and light, remembrance and oblivion, coming into existence and disappearing in death play their originary co-belonging, or co-figuration. Existence belongs to this opening and is exposed to its coming to presence: it is on the basis of this originary opening, this originary historical which is revealed to this mortal being called ‘man,’ on the basis of this revelation, man founds something like politics and history. There thus comes into existence out of this freedom, out of this (...) “play space”2, this field called ‘polis’3 where there takes place war and festival, where historical revolutions tear apart history, brings ruptures and discontinuities in the very mode of his existence, where man seeks the foundation of his own foundation, where occurs the dialectics of negativity between man and man, where man puts at stake his own death, his own dissolution, and by the power of his own dissolution stands in relation to the total world that he seeks to dominate. This means that man’s attempts to metaphysically found his own political and historical existence must presuppose a far more originary non-foundation, the differentiating revealing of the open, the ungrounded spacing play, or playing space of natality and mortality.

Recent work suggests that DNA replication origins are regulated by the number of multiple mini‐chromosome maintenance (MCM) complexes loaded. Origins are defined by the loading of MCM – the replicative helicase which initiates DNA replication and replication kinetics determined by origin's location and firing times. However, activation of MCM is heterogeneous; different origins firing at different times in different cells. Also, more MCMs are loaded in G1 than are used in S phase. These aspects of MCM biology are explained by (...) the observation that multiple MCMs are loaded at origins. Having more MCMs at early origins makes them more likely to fire, effecting differences in origin efficiency that define replication timing. Nonetheless, multiple MCM loading raises new questions, such as how they are loaded, where these MCMs reside at origins, and how their presence affects replication timing. In this review, we address these questions and discuss future avenues of research. (shrink)
