We have identified a sample of 53 societies outside of the classical Himalayan and Marquesean area that permit polyandrous unions. Our goal is to broadly describe the demographic, social, marital, and economic characteristics of these societies and to evaluate some hypotheses of the causes of polyandry. We demonstrate that although polyandry is rare it is not as rare as commonly believed, is found worldwide, and is most common in egalitarian societies. We also argue that polyandry likely existed during early human (...) history and should be examined from an evolutionary perspective. Our analysis reveals that it may be a predictable response to a high operational sex ratio favoring males and may also be a response to high rates of male mortality and, possibly, male absenteeism. Other factors may contribute, but our within-polyandry sample limits analysis. (shrink)

There is a well-entrenched schism on the frequency, intensity, and evolutionary significance of warfare among hunter-gatherers compared with large-scale societies. To simplify, Rousseauians argue that warfare among prehistoric and contemporary hunter-gatherers was nearly absent and, if present, was a late cultural invention. In contrast, so-called Hobbesians argue that violence was relatively common but variable among hunter-gatherers. To defend their views, Rousseauians resort to a variety of tactics to diminish the apparent frequency and intensity of hunter-gatherer warfare. These tactics include redefining (...) war, censoring ethnographic accounts of warfare in comparative analyses, misconstruing archaeological evidence, and claiming that outside contact inflates the intensity of warfare among hunter-gatherers. These tactics are subject to critical analysis and are mostly found to be wanting. Furthermore, Hobbesians with empirical data have already established that the frequency and intensity of hunter-gatherer warfare is greater compared with large-scale societies even though horticultural societies engage in warfare more intensively than hunter-gatherers. In the end I argue that although war is a primitive trait we may share with chimpanzees and/or our last common ancestor, the ability of hunter-gatherer bands to live peaceably with their neighbors, even though war may occur, is a derived trait that fundamentally distinguishes us socially and politically from chimpanzee societies. It is a point often lost in these debates. (shrink)

Considerable research on helpers-at-the-nest demonstrates the positive effects of firstborn daughters on a mother’s reproductive success and the survival of her children compared with women who have firstborn sons. This research is largely restricted to agricultural settings. In the present study we ask: “Does ‘daughter first’ improve mothers’ reproductive success in a hunting and gathering context?” Through an analysis of 84 postreproductive women in this population we find that the sex of the first- or second-born child has no effect on (...) a mother’s fertility or the survival of her offspring. We conclude that specific environmental and economic factors underlay the helpers-at-the-nest phenomenon. (shrink)

_Yanomami_ raises questions central to the field of anthropology—questions concerning the practice of fieldwork, the production of knowledge, and anthropology's intellectual and ethical vision of itself. Using the Yanomami controversy—one of anthropology's most famous and explosive imbroglios—as its starting point, this book draws readers into not only reflecting on but refashioning the very heart and soul of the discipline. It is both the most up-to-date and thorough public discussion of the Yanomami controversy available and an innovative and searching assessment of (...) the current state of anthropology. The Yanomami controversy came to public attention through the publication of Patrick Tierney's best-selling book, _Darkness in El Dorado,_ in which he accuses James Neel, a prominent geneticist who belonged to the National Academy of Sciences, as well as Napoleon Chagnon, whose introductory text on the Yanomami is perhaps the best-selling anthropological monograph of all time, of serious human rights violations. This book identifies the ethical dilemmas of the controversy and raises deeper, structural questions about the discipline. A portion of the book is devoted to a unique roundtable in which important scholars on different sides of the issues debate back and forth with each other. This format draws readers into deciding, for themselves, where they stand on the controversy’s—and many of anthropology’s—central concerns. All of the royalties from this book will be donated to helping the Yanomami improve their healthcare. (shrink)

In this study meal sharing is used as a way of quantifying food transfers between households. Traditional food-sharing studies measure the flow of resources between households. Meal sharing, in contrast, measures food consumption acts according to whether one is a host or a guest in the household as well as the movement of people between households in the context of food consumption. Our goal is to test a number of evolutionary models of food transfers, but first we argue that before (...) one tests models of who should receive food one must understand the adaptiveness of food transfers. For the Ye’kwana, economies of scale in food processing and preparation appear to set the stage for the utility of meal sharing. Evolutionary models of meal sharing, such as kin selection and reciprocal altruism, are evaluated along with non-evolutionary models, such as egalitarian exchange and residential propinquity. In addition, a modified measure of exchange balance—proportional balance—is developed. Reciprocal altruism is shown to be the strongest predictor of exchange intensity and balance. (shrink)

Birth order has been examined over a wide variety of dimensions in the context of modern populations. A consistent message has been that it is better to be born first. The analysis of birth order in this paper is different in several ways from other investigations into birth order effects. First, we examine the effect of birth order in an egalitarian, small-scale, kin-based society, which has not been done before. Second, we use a different outcome measure, fertility, rather than outcome (...) measures of social, psychological, or economic success. We find, third, that being born late in an egalitarian, technologically simple society rather than being born early has a positive outcome on fertility, and fourth, that number of older siblings and sibling set size are even stronger predictors of fertility, especially for males.

In the analysis of intergenerational transfer, several improvements can be made. First, following kin selection theory, grandparents have kin other than grandchildren in which to invest and therefore any investigation into grandparents should take this perspective. Secondly, how transfers actually enhance the survivorship of younger relatives such as grandchildren must be better measured, especially in the ethnographic literature. Finally, the problem of indirect investments or targeting must be considered.

While effective institutional practices are critical for the evolution of peace certain factors deter their effectiveness. In-group and out-group dynamics may make peace difficult between culturally distinct groups. Critical ecological conditions often lead to intractable conflict over resources. And within group conflicts of interest most prominently between generations may inhibit effective peace making.

In his state-of-the-art review, Gurven compares evolutionary theories of food transfers in ethnographic settings. Although this is useful, I suggest that one must first try to determine the utility of food transfers before making predictions about which parties ought to receive food. In addition, I argue that tests of kin selection theory present a special problem in food transfers.

In The Fold, Deleuze regards Raymond Ruyer as the most recent of Leibniz’s great disciples. This claim is not self-evident, since Ruyer often criticises Leibniz and stresses the divergence of his theory from Leibniz’s monadological metaphysics. Therefore, while Ruyer does not seem to regard himself as indebted to Leibniz, and as his psychobiology is not always reconcilable with Leibniz’s philosophy, it is necessary to explore what is at stake in Deleuze’s recognition of Ruyer as a Leibnizian thinker. This essay (...) foregrounds the tacit intertwining between Leibniz and Ruyer, which can, on the one hand, contribute to Leibniz’s scholarship and uncover the contemporaneity of his thought, and on the other hand, expose certain revealing Ruyerian moments in Deleuze’s immanent philosophy.

This paper offers a practical argument for metaphysical emergence. The main message is that the growing reliance on so-called irrational scientific methods provides evidence that objects of science are indecomposable and as such, are better described by metaphysical emergence as opposed to the prevalent reductionistic metaphysics. I show that a potential counterargument that science will eventually reduce everything to physics has little weight given where science is heading with its current methodological trend. I substantiate my arguments by detailed examples from (...) biological engineering, but the conclusions are extendable beyond that discipline. (shrink)

This book traces the development of theories of the self and personal identity from the ancient Greeks to the present day. From Plato and Aristotle to Freud and Foucault, Raymond Martin and John Barresi explore the works of a wide range of thinkers and reveal the larger intellectual trends, controversies, and ideas that have revolutionized the way we think about ourselves. The authors open with ancient Greece, where the ideas of Plato, Aristotle, and the materialistic atomists laid the groundwork (...) for future theories. They then discuss the ideas of the church fathers and medieval and Renaissance philosophers, including St. Paul, Philo, Augustine, Aquinas, and Montaigne. In their coverage of the emergence of a new mechanistic conception of nature in the seventeenth century, Martin and Barresi note a shift away from religious and purely philosophical notions of self and personal identity to more scientific and social conceptions, a trend that has continued to the present day. They explore modern philosophy and psychology, including the origins of different traditions within each discipline, and explain both the theoretical relevance of feminism and gender and ethnic studies and also the ways that Derrida and other recent thinkers have challenged the very idea that a unified self or personal identity even exists. Martin and Barresi cover a number of issues broached by philosophers and psychologists, such as the existence of a fixed and unchanging self and whether the concept of the soul has a use outside of religious contexts. They address the question of whether notions of the soul and the self are still viable in today's world. Together, they reveal the fascinating ways in which great thinkers have grappled with these and other questions and the astounding impact their ideas have had on the development of self-understanding in the west.

In a devastating critique Raymond Tallis exposes the exaggerated claims made for the ability of neuroscience and evolutionary theory to explain human consciousness, behaviour, culture and society. While readily acknowledging the astounding progress neuroscience has made in helping us understand how the brain works, Tallis directs his guns at neuroscience’s dark companion – "Neuromania" as he describes it – the belief that brain activity is not merely a necessary but a sufficient condition for human consciousness and that consequently our (...) everyday behaviour can be entirely understood in neural terms. With the formidable acuity and precision of both clinician and philosopher, Tallis dismantles the idea that "we are our brains", which has given rise to a plethora of neuro-prefixed pseudo-disciplines laying claim to explain everything from art and literature to criminality and religious belief, and shows it to be confused and fallacious, and an abuse of the prestige of science, one that sidesteps a whole range of mind–body problems. The belief that human beings can be understood essentially in biological terms is a serious obstacle, argues Tallis, to clear thinking about what human beings are and what they might become. To explain everyday behaviour in Darwinian terms and to identify human consciousness with the activity of the evolved brain denies human uniqueness, and by minimising the differences between us and our nearest animal kin, misrepresents what we are, offering a grotesquely simplified and degrading account of humanity. We are, shows Tallis, infinitely more interesting and complex than we appear in the mirror of biologism. Combative, fearless and always thought-provoking, _Aping Mankind _is an important book, one that scientists, cultural commentators and policy-makers cannot ignore. (shrink)

The status of continuity in Deleuze’s metaphysics is a subject of debate. Deleuze calls the virtual, in Difference and Repetition, an Ideal continuum, and the differential relations that constitute the Ideal imply the continuity of this field. But, Deleuze does not hesitate to formulate the same field by the affirmation of divergence (incompossibility) that can be regarded as a form of discontinuity. It is, hence, unclear how these two ostensibly contradictory accounts might reconcile. This article attempts to reconstitute a Deleuzian (...) theory of continuity through Leibniz whose philosophy is equally subject to a tension between the law of continuity, prevalent in his mathematics and metaphysics, and the discontinuity or absolute individuality of monads. By reorienting The Fold around the motif of continuity a new conceptual space is opened for continuity qua heterogeneity-and-inseparability. Then, enfolding the conceptual personae of The Fold onto Difference and Repetition reveals the tacit though decisive presence of different types of continuity operational in Deleuze’s metaphysics that will be called divergent, intensive, torsional, and tenorsional continuities.

What are the origins of human difference? The Hand, which is the first part of a bold philosophical inquiry into the nature of the difference between human beings and other animals, argues that it is the result of a complex sequence of events which began several million years ago with the evolution of the human hand.Possession of a fully developed hand profoundly transformed the relationship of the human being to its own body, thus altering the relationship between humans and the (...) natural world. The interaction of the hand with the rest of the body brought about self-consciousness and laid the foundations for the unique sense of agency that is experienced by humans. Crucially, the hand inspired the tool-use that has come to dominate human life and which has led to the emergence of the complex symbolic systems - most importantly language - that underpin civilisation.The book also celebrates the hand in human life: the almost miraculous complexity of its manipulative, exploratory and communicative functions. Raymond Tallis combines philosophical reflection with a light-hearted look at gestures, the role of each finger, the origins of numbers - and the case for and against what he names 'handkind'.The Hand is the first of three volumes. The other titles are I Am: A Philosophical Inquiry into First-Person Being and The Knowing Animal: A Philosophical Inquiry into Truth and Knowledge. (shrink)

Political ideologies devoted either to the elimination or exclusion of religion from, or to its imposition on, the public sphere, and which are prepared in either case to capture State Power to achieve their vision for Society, must inexorably deny to citizens fundamental human rights and civil liberties – in a globalizing world where sustainable societies must become more culturally heterogeneous and where the continuing rise of religion is inevitable, so argues the author in this article. What is needed is (...) a polity that privileges tenets of democratic pluralism, human rights and multiculturalism over and above secularism or any of its various oppositional frameworks. The author posits that a Secular State is incapable of guaranteeing fundamental human rights to its citizens within a democratic framework. Secularism never triumphed as the ideology of state without important civil liberties being abjured. At the same time, any State applying Shari'ah as public law, must not only deny to non-Muslims fundamental human rights, but will also eventually deny Muslims their self-determination at both personal and collective levels and will in due course cease to be a State. The author calls for a re-thinking of human rights in order to make them more acceptable universally across diverse cultures. (shrink)

Psychological disorders such as depression are common. Many of these disorders can be evaluated and diagnosed, and above all they are preventable. This study was conducted with the aim of determining depression prevalence rate and its related factors among students of Quchan University of Technology, Quchan, Iran. In a cross-sectional study, 359 students were selected by using simple random sampling. Demographic characteristics were gathered and subjects were evaluated by the Beck’s Depression Inventory and the Beck’s Anxiety Inventory. SPSS software was (...) used for statistical analysis and logistic regression, Chi-square and Mann-Whitney tests were utilized for this purpose. The age mean of students was 21.02±2.57. 93 subjects suffer from depression and 266 subjects are not depressed..There is no significant difference between depression and each of these variables: gender, body mass index, marital status, field of study, living in dormitory, and depression ; but there was significant difference between depressed and non-depressed students in terms of salary, anxiety, educational level, and satisfaction with field of study. According to the results, anxiety, educational level, satisfaction with field of study and monthly income impact depression. Improving the students' consultancy in universities can be helpful to decrease anxiety. In addition, consultants can prepare students for selecting their favorite field of study. Also, it is suggested that university officials provide financial facilities such as interest-free loan for students. (shrink)

There is no consensus regarding whether Gilles Deleuze offers a cogent theory of the Other. Deleuze develops the notion of the Other-structure, but given his scarce remarks on this concept, his treatment of this issue is debated. This article argues that to elucidate Deleuze's philosophy of the Other, his notion of the Other-structure must be analyzed in parallel to Edmund Husserl's intersubjective theory. This comparison, made possible by Natalie Depraz's reading of the Husserlian alterity, reveals nuanced phenomenological traces in Deleuze's (...) Other-structure and its implicated structural moments while substantiating his affirmation of the Otherless world, as an impetus to surpass phenomenology. (shrink)

This book explores how people's subjective, felt experiences of their bodies in action provide part of the fundamental grounding for human cognition and language. Cognition is what occurs when the body engages the physical and cultural world and must be studied in terms of the dynamical interactions between people and the environment. Human language and thought emerge from recurring patterns of embodied activity that constrain ongoing intelligent behavior. We must not assume cognition to be purely internal, symbolic, computational, and disembodied, (...) but seek out the gross and detailed ways that language and thought are inextricably shaped by embodied action. Embodiment and Cognitive Science describes the abundance of empirical evidence from many disciplines, including work on perception, concepts, imagery and reasoning, language and communication, cognitive development, and emotions and consciousness, that support the idea that the mind is embodied.

Neuroscience has made astounding progress in the understanding of the brain. What should we make of its claims to go beyond the brain and explain consciousness, behaviour and culture? Where should we draw the line? In this brilliant critique Raymond Tallis dismantles "Neuromania", arising out of the idea that we are reducible to our brains and "Darwinitis" according to which, since the brain is an evolved organ, we are entirely explicable within an evolutionary framework. With precision and acuity he (...) argues that the belief that human beings can be understood in biological terms is a serious obstacle to clear thinking about what we are and what we might become. Neuromania and Darwinitis deny human uniqueness, minimise the differences between us and our nearest animal kin and offer a grotesquely simplified account of humanity.

In Cognitive science and philosophy of consciousness, the explanatory gap, following Joseph Levine, refers to the unintelligible link between our conscious mental life and its corresponding objective physical explanation; the gap in our understanding of how consciousness is related to a physical or a physiological substrate :354–361, 1983). David Chalmers holds the explanatory gap as the evidence for a form of metaphysical dualism between consciousness and physical reality. On the other hand, McGinn takes it as an epistemic rather than an (...) ontological gap. Considering the recent advances in neuroscience, however, the reductionist approaches have become replete, which attempt to reduce consciousness and subjectivity to neurobiological accounts. On this view, consciousness mirrors the brain mechanisms, and the self is formulated as an illusory product or construct of neuronal processes. Thomas Fuchs, who is committed to embodied and enactive approaches toward cognition, in Ecology of the Brain, espouses an enactive-ecological perspective concerning the problem of the explanatory gap. He develops an account of human’s life in its dual aspects of the living body and lived body which, on the one hand, defies the ontological dualism and, on the other hand, avoids drifting towards any form of reductionism. Often, the ontologically monistic approaches to the explanatory gap have inclined to a form of reductionism because they conceive consciousness as either identical with its physiological substrate or caused by it, where in both cases, consciousness is claimed to be explainable within the framework of physicalism. Fuchs, however, defends an ontological monism which remains irreconcilable with reductionism. In his account of dual aspects, there is no interaction or impact between the sphere of subjectivity and nature; however, these two aspects imply one another. In this essay, I will develop the philosophical justification of the above reformulation of the mind–body problem and employing the analogy of light will canvass the paradoxical relationship between dual aspects in a phenomenological framework.

There is a research programme in linguistics that is founded on describing language as an emergent phenomenon. This paper clarifies how the core concept of emergence is deployed in this emergentist programme. We show that if one adopts the weak understandings of the concept of language emergence, the emergentist programme is not fundamentally different from the other non-emergentist research programmes in linguistics. On the other hand, if one adopts the stronger understandings of emergence then the programme would have a unique (...) character, but at the cost of some corollaries (philosophical, but not only) which the emergentist linguists would seemingly want to avoid. We show that if the emergentists accept those corollaries, the resulting hypothetical emergentist programme would be totally different from the emergentist programme in its present shape. We conclude that the emergentist programme, as it stands, should be either abandoned or reshaped in both theory and methodology. (shrink)

What is law? Does it have a purpose? What is its relationship with justice? Do we have a moral duty to obey the law? These sorts of questions lie at the heart of jurisprudence. Moreover, every substantive or 'black letter' branch of the law raises questions about its own meaning and function. The law of contract cannot be properly understood without an appreciation of the concepts of rights and duties. The law of tort is directly related to several economic theories (...) of compensation. The criminal law is inextricably linked to philosophies of punishment? Understanding Jurisprudence explores these problems and provides an engaging introduction to the central issues of legal theory. The book navigates the reader through legal philosophy's fundamental concepts, concerns, and controversies.

The tsunami effect of the COVID-19 pandemic is affecting many aspects of scientific activities. Multidisciplinary experimental studies with international collaborators are hindered by the closing of the national borders, logistic issues due to lockdown, quarantine restrictions, and social distancing requirements.

Sharing innovative solutions between researchers is in high demand in this situation. The aim of this paper is (...) to share our successful practice of using web-based communication and remote control software for real-time long-distance control of brain stimulation. This solution may guide and encourage researchers to cope with restrictions and has the potential to help expanding international collaborations by lowering travel time and costs. (shrink)

Recently, due to the rapid progress of computer technology, researchers develop an effective computer program to enhance the achievement of the student in learning process, which is Intelligent Tutoring System (ITS). Science is important because it influences most aspects of everyday life, including food, energy, medicine, leisure activities and more. So learning science subject at school is very useful, but the students face some problem in learning it. So we designed an ITS system to help them understand this subject easily (...) and smoothly by analyzing it and explaining it in a systematic way. In this paper, we describe the design of an Intelligent Tutoring System for teaching science for grade seven to help students know the 7 characteristics for living things smoothly. The system provides all topics of living things and generates some questions for each topic and the students should answer these questions correctly to move to the next level. In the result of an evaluation of the ITS, students like the system and they said that it is very useful for them and for their studies. (shrink)

To understand how individuals adapt to and anticipate each other in joint tasks, we employ a bidirectional delay–coupled dynamical system that allows for mutual adaptation and anticipation. In delay–coupled systems, anticipation is achieved when one system compares its own time‐delayed behavior, which implicitly includes past information about the other system’s behavior, with the other system’s instantaneous behavior. Applied to joint music performance, the model allows each system to adapt its behavior to the dynamics of the other. Model predictions of asynchrony (...) between two simultaneously produced musical voices were compared with duet pianists’ behavior; each partner performed one voice while auditory feedback perturbations occurred at unpredictable times during live performance. As the model predicted, when auditory feedback from one musical voice was removed, the asynchrony changed: The pianist’s voice that was removed anticipated (preceded) the actions of their partner. When the auditory feedback returned and both musicians could hear each other, they rapidly returned to baseline levels of asynchrony. To understand how the pianists anticipated each other, their performances were fitted by the model to examine change in model parameters (coupling strength, time‐delay). When auditory feedback for one or both voices was removed, the fits showed the expected decrease in coupling strength and time‐delay between the systems. When feedback about the voice(s) returned, the coupling strength and time‐delay returned to baseline. These findings support the idea that when people perform actions together, they do so as a coupled bidirectional anticipatory system. (shrink)

The question of the ethical life is arguably one of the most compelling, and urgent, questions of our time. As Peter Singer, among others, has pointed out, almost 10 million children die each year due to poverty, some of whom would not die if the amount of aid that we now offer increases significantly. As Singer has also pointed out, the exploitation of human beings and other animals is a major ethical and practical concern. There can be little reasonable doubt (...) that pain and suffering abound, in the world today, due to many causes such as poverty, disease, environmental degradation and destruction and anthropocentrism among others, just as there can be little reasonable doubt that some of the pain and suffering is preventable. So, what does it mean to live ethically today? Does it mean taking the point of view of the universe, as Sidgwick put it, memorably, rather than a narrow anthropocentric or speciesist view? Does it mean living in accordance with duties or obligations, or in light of recognised virtues, or with the minimisation of pain and suffering primarily in mind? Does it entail a consideration of the interests of other species and a rejection of the principle of the sanctity of human life? Does it mean not eating animals when other healthy alternatives are available, especially when those animals have been treated in ways that are inconsistent with their interests, whatever they may be? Does it mean taking active steps to reduce poverty on our part on a day to day basis? Is ethics exhausted in some sense today? And if we could reach some consensus on these questions, what difference would the ethical life make? Some argue that speciesism and the exploitation of human beings and other animals might diminish; that pain and suffering, especially gratuitous pain and suffering, would decrease, or at the very least, not increase; or that we will become more aware of the limitations of things such as "the traditional ethic of the sanctity of life", as Singer calls it. Some argue that the ethical life is closely related to a life of relationships, reflection and deliberation, all of which deepen our understanding and enrich us personally. Others argue that the ethical life is closely related to our search for a meaningful life - that the ethical life can help us to find meaning in a world in which "meaning", defined broadly, can seem elusive, enigmatic or unsubstantial. These and related issues and questions are explored in this collection, which illustrates the relevance, vitality and dynamism of ethics today. (shrink)

Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces should ideally operate un-tethered and allow chronic longitudinal manipulations in the freely moving animal. In this study, we designed a new intracortical BCI feasible of telemetric recording and stimulating local gray and white matter of visual neural circuit after irradiation exposure. To increase the translational reliance, we put forward a Göttingen minipig model. The (...) animal was stereotactically irradiated at the level of the visual cortex upon defining the target by a fused cerebral MRI and CT scan. A fully implantable neural telemetry system consisting of a 64 channel intracortical multielectrode array, a telemetry capsule, and an inductive rechargeable battery was then implanted into the visual cortex to record and manipulate local field potentials, and multi-unit activity. We achieved a 3-month stability of the functionality of the un-tethered BCI in terms of telemetric radio-communication, inductive battery charging, and device biocompatibility for 3 months. Finally, we could reliably record the local signature of sub- and suprathreshold neuronal activity in the visual cortex with high bandwidth without complications. The ability to wireless induction charging combined with the entirely implantable design, the rather high recording bandwidth, and the ability to record and stimulate simultaneously put forward a wireless BCI capable of long-term un-tethered real-time communication for causal preclinical circuit-based closed-loop interventions.

Impoliteness in student emails to faculty can have negative consequences. However, the nuances of perceived impoliteness by faculty with different language backgrounds have not been thoroughly studied in the literature. This paper explores how emails written by non-native English-speaking students are perceived impolite by faculty depending on social identity variables such as native speaker status, gender, and seniority. Participants read six emails and rated their perceptions of the emails on a questionnaire. The items on the questionnaire were about lack of (...) face enhancement, use of face threat, acknowledgment of imposition, and not giving a choice in complying with requests. Results suggest that in their perceptions of the lack of face enhancement, senior faculty seemed to be more tolerant than their junior counterparts. Further, non-native speakers of English were found to be more tolerant of the lack of acknowledgment of imposition. However, no significant association was observed between the social identity of the faculty and their perception of face threat nor between social identity and giving a choice in complying with requests. The paper has implications for raising the awareness of the faculty and students about their potential biases in academic correspondence. (shrink)

Distinguished French sociologist Raymond Boudon presents here a critical theory history of the concept of ideology. His highly original and lucidly argued study addresses the core question of any account of ideology. How do individuals come to adhere to false or apparently irrational beliefs, and how do such beliefs become collectively accepted as true? Boudon begins by providing an exhaustive and subtle critique of sociological explanations of ideology from early conceptions to its current usage in the works of Barthes, (...) Foucault, Habermas, Sartre, and others. He then offers his own interpretation of the origins and emergence of ideological beliefs. In opposition to those views which associate ideology with irrationalism, Boudon shows that ideologies are a natural ingredient of social life; he develops a rationalist theory that helps to explain why certain ideas are believed by individuals and thereby effective in the social world. Finally, he examines case studies of two modern-day ideologies--developmentalism and Third Worldism. Moving easily across disciplinary boundaries, Boudon's provocative contribution to a subject of growing significance will be of great interest to scholars in sociology and social theory, as well as philosophy, political science, and development studies.

The suspension system is referred to as the set of springs, shock absorbers, and linkages that connect the car to the wheel system. The main purpose of the suspension system is to provide comfort for the passengers, which is created by reducing the effects of road bumpiness. It is worth noting that reducing the effects of such vibrations also diminishes the noise and undesirable sound as well as the effects of fatigue on mechanical parts of the vehicle. Due to the (...) importance of the abovementioned issues, the objective of this article is to reduce such vibrations on the car by implementing an active control method on the suspension system. For this purpose, a conventional first-order sliding mode controller has been designed for stochastic control of the quarter-car model. It is noteworthy that this controller has a significant ability to overcome the stochastic effects, uncertainty, and deal with nonlinear factors. To design a controller, the governing dynamical equation of the quarter-car system has been presented by considering the nonlinear terms in the springs and shock absorber, as well as taking into account the uncertainty factors in the system and the actuator. The design process of the sliding mode controller has been presented and its stability has been investigated in terms of the Lyapunov stability. In the current research, road surface variations are considered as Gaussian white noise. The dynamical system behavior for controlled and uncontrolled situations has been simulated and the extracted results have been presented. Besides, the effects of existing uncertainty in the suspension system and actuator have been evaluated and controller robustness has been checked. Also, the obtained quantitative and qualitative compressions have been presented. Moreover, the effect of controller parameters on the basin of attraction set and its extensiveness has been assessed. The achieved results have indicated the good performance and significant robustness of the designed controller to stabilize the suspension system and mitigate the effects of road bumpiness in the presence of uncertainty and noise factors.
