Memristor-based oscillators are of recent interest, and hence, in this paper, we introduce a new Wien bridge oscillator with a fractional-order memristor. The novelty of the proposed oscillator is the multistability feature and the wide range of fractional orders for which the system shows chaos. We have investigated the various dynamical properties of the proposed oscillator and have presented them in detail. The oscillator is then realized using off-the-shelf components, and the results are compared with that of the numerical results. (...) A combination synchronization scheme is proposed which uses more than one driver systems to synchronize with one response system. Indeed, we use two different techniques where the first one consists of splitting the transmitted signals into two parts where each part is loaded in different drive systems, while the second one consists of dividing time into different intervals and loading the signals in different drive systems. Such techniques improve the antiattack capability of the systems when used for secure communication. (shrink)

This article presents a novel challenge to epistemic internalism. The challenge rests on a set of cases which feature subjects forming beliefs under conditions of “bad ideology”—that is, conditions in which pervasively false beliefs have the function of sustaining, and are sustained by, systems of social oppression. In such cases, the article suggests, the externalistic view that justification is in part a matter of worldly relations, rather than the internalistic view that justification is solely a matter of how things stand (...) from the agent’s individual perspective, becomes the more intuitively attractive theory. But these “bad ideology” cases do not merely yield intuitive verdicts that favor externalism over internalism. These cases are, moreover, analogous to precisely those canonical cases widely taken to be counterexamples to externalism: cases featuring brains-in-vats, clairvoyants, and dogmatists. That is, such “bad ideology” cases are, in all relevant respects, just like cases that are thought to count against externalism—except that they intuitively favor externalism. This, the author argues, is a serious worry for internalism. What is more, it bears on the debate over whether externalism is a genuinely “normative” epistemology. (shrink)

This paper explains how the practice of ‘no platforming’ can be reconciled with a liberal politics. While opponents say that no platforming flouts ideals of open public discourse, and defenders see it as a justifiable harm-prevention measure, both sides mistakenly treat the debate like a run-of-the-mill free speech conflict, rather than an issue of academic freedom specifically. Content-based restrictions on speech in universities are ubiquitous. And this is no affront to a liberal conception of academic freedom, whose purpose isn’t just (...) to protect the speech of academics, but also to give them the prerogative to determine which views and speakers have sufficient disciplinary credentials to receive a hearing in academic contexts. No platforming should therefore be acceptable to liberals, in principle, in cases where it is used to support a university culture that maintains rigorous disciplinary standards, by denying attention and credibility to speakers without appropriate disciplinary credentials.

We suffer from genealogical anxiety when we worry that the contingent origins of our representations, once revealed, will somehow undermine or cast doubt on those representations. Is such anxiety ever rational? Many have apparently thought so, from pre-Socratic critics of Greek theology to contemporary evolutionary debunkers of morality. One strategy for vindicating critical genealogies is to see them as undermining the epistemic standing of our representations—the justification of our beliefs, the aptness of our concepts, and so on. I argue that (...) this strategy is not as promising as it might first seem. Instead, I suggest that critical genealogies can wield a sort of meta-epistemic power; in so far as we wish to resist the genealogical critic, we are under pressure to see ourselves as the beneficiaries of a certain kind of good luck: what I call genealogical luck. But there is also a resolutely non-epistemic way of understanding the power of critical genealogies, one that is essential, I argue, for understanding the genealogical projects of various theorists, including Nietzsche and Catharine MacKinnon. For critical genealogies can reveal what it is that our representations do—and what we, in turn, might do with them. (shrink)

Since its appearance over a decade ago, Timothy Williamson's anti-luminosity argument has come under sustained attack. Defenders of the luminous overwhelmingly object to the argument's use of a certain margin-for-error premise. Williamson himself claims that the premise follows easily from a safety condition on knowledge together with his description of the thought experiment. But luminists argue that this is not so: the margin-for-error premise either requires an implausible interpretation of the safety requirement on knowledge, or it requires other equally implausible (...) assumptions. In this paper I bolster the margin-for-error premise against these attacks by recasting Williamson's own two-part defence, the first part intended to work on the assumption that there is no constitutive connection between the phenomenal and the doxastic, and the second intended to work without this assumption. Pace various luminists, I argue that the appeals to safety needed for Williamson's two-part defence are plausible. I also argue that all that is needed to generate the margin-for-error premise from these safety conditions is an empirical assumption about the kinds of creatures we are: that is, creatures whose beliefs are structured by certain dispositions. By recasting the anti-luminosity argument in this way, we can understand what is really at stake in the debate about luminosity: that is, whether we are luminous. (shrink)

The role of holistic or parts-based processing in face identification has been explored mostly with neutral faces. In the current study, we investigated the nature of processing (holistic vs. parts) in recognition memory for faces with emotional expressions. There were two phases in this experiment: learning phase and test phase. In the learning phase participants learned face–name associations of happy, neutral, and sad faces. The test phase consisted of a two-choice recognition test (whole face, eyes, or mouth) given either immediately (...) or after a 24-hour delay. Results indicate that emotional faces were remembered better than neutral faces and performance was better with whole faces as compared to isolated parts. The performance in immediate and delayed recognition interacted with emotional information. Sad eyes and happy mouth were remembered better in the delayed recognition condition. These results suggest that in addition to holistic processing, specific parts–emotion combinations play a critical role in delayed recognition memory. (shrink)

A cohesive power of a structure is an effective analog of the classical ultrapower of a structure. We start with a computable structure, and consider its effective power over a cohesive set of natural numbers. A cohesive set is an infinite set of natural numbers that is indecomposable with respect to computably enumerable sets. It plays the role of an ultrafilter, and the elements of a cohesive power are the equivalence classes of certain partial computable functions determined by the cohesive (...) set. Thus, unlike many classical ultrapowers, a cohesive power is a countable structure. In this paper we focus on cohesive powers of graphs, equivalence structures, and computable structures with a single unary function satisfying various properties, which can also be viewed as directed graphs. For these computable structures, we investigate the isomorphism types of their cohesive powers, as well as the properties of cohesive powers when they are not isomorphic to the original structure.

We examined proactive and reactive control effects in the context of task-relevant happy, sad, and angry facial expressions on a face-word Stroop task. Participants identified the emotion expressed by a face that contained a congruent or incongruent emotional word. Proactive control effects were measured in terms of the reduction in Stroop interference as a function of previous trial emotion and previous trial congruence. Reactive control effects were measured in terms of the reduction in Stroop interference as a function of current (...) trial emotion and previous trial congruence. Previous trial negative emotions exert greater influence on proactive control than the positive emotion. Sad faces in the previous trial resulted in greater reduction in the Stroop interference for happy faces in the current trial. However, current trial angry faces showed stronger adaptation effects compared to happy faces. Thus, both proactive and reactive control mechanisms are dependent on emotional valence of task-relevant stimuli. (shrink)

Mindfulness can be understood as the mental ability to focus on the direct and immediate perception or monitoring of the present moment with a state of open and nonjudgmental awareness. Descriptions of mindfulness and methods for cultivating it originated in eastern spiritual traditions. These suggest that mindfulness can be developed through meditation practice to increase positive qualities such as awareness, insight, wisdom, and compassion. In this article we focus on the relationships between mindfulness, with associated meditation practices, and the cognitive (...) neuroscience of attention and awareness. Mindful awareness is related to distributed attention, phenomenal consciousness, and momentary self-awareness, as characterized by recent findings in cognitive psychology and neuroscience as well as in influential consciousness models. Finally, we outline an integrated neurocognitive model of mindfulness, attention, and awareness, with a key role of prefrontal cortex. (shrink)

Perceptual load plays a critical role in identification and awareness of stimuli. Given the differences in emotion–attention interactions, we investigated the perception of distractor emotional faces in two different load conditions under divided attention with a task based on the inattentional blindness paradigm. Participants performed a low- or high-load task with a string of letters presented against a happy, sad or neutral face (in a circular form) as the background. Participants were asked to identify the face that appeared in the (...) critical trial. Results indicate an interaction between emotion and load. First, identification of faces with happy expression was better than chance and unaffected by load. Second, performance was worse than chance for faces with sad expression in the high-load condition, indicating inhibition of unattended sad distractor faces in the critical trial. This indicates that inhibitory processes during a difficult attentional task under divided attention influence subsequent perception of distractor stimuli especially sad faces. The results have implications for the theories of selective attention as well as the role of emotions in conscious perception. (shrink)

What is it for an analytic philosopher to do ideology critique? Just how useful are the proprietary tools of analytic philosophy when it comes to thinking about ideology, and in what sense ‘useful’, and to whom? And to what end might analytic philosophers pursue ideology critique? Here I attempt to say something about these questions by commenting on a recent contribution to analytic ideology critique, Jason Stanley’s How Propaganda Works.¿Qué significa para un filósofo analítico hacer crítica de la ideología? ¿En (...) qué medida son útiles las herramientas propias de la filosofía analítica cuando se trata de pensar sobre la ideología, y en qué sentido de ‘útiles’, y para quién? Y ¿con qué fin podrían emprender los filósofos analíticos la crítica de la ideología? Aquí pretendo decir algo acerca de estas cuestiones comentando una reciente contribución a la crítica analítica de la idelogía, la obra de Jason Stanley How Propaganda Works. (shrink)

What ought one to do, epistemically speaking, when faced with a disagreement? Faced with this question, one naturally hopes for an answer that is principled, general, and intuitively satisfying. We want to argue that this is a vain hope. Our claim is that a satisfying answer will prove elusive because of non-transparency: that there is no condition such that we are always in a position to know whether it obtains. When we take seriously that there is nothing, including our own (...) minds, to which we have assured access, the familiar project of formulating epistemic norms is destabilized. In this paper, we will show how this plays out in the special case of disagreement. But we believe that a larger lesson can ultimately be extracted from our discussion: namely, that non-transparency threatens our hope for fully satisfying epistemic norms in general. (shrink)

In the early 1980s, U.S. universities began regulating sexual relationships between professors and students. Such regulations are routinely justified by a rationale drawn from sexual-harassment law in the employment context: the power differential between professor and student precludes the possibility of genuine consent on the student’s part. This rationale is problematic, as feminists in the 1980s first observed, for its protectionist and infantilizing attitude toward (generally) women students. But it is also problematic in that it fails to register what is (...) truly ethically troubling about consensual professor-student sex. A professor’s having sex with his student constitutes a pedagogical failure: that is, a failure to satisfy the duties that arise from the practice of teaching. What is more, much consensual professor-student sex constitutes a patriarchal failure: such relationships often feed on, and reinforce, women’s second-class standing in higher education. As such, these relationships can thwart the legal right of women students, under Title IX, to exist in the university on equal terms with their male counterparts. Whether or not we should ultimately favor such an interpretation of Title IX—whether or not, that is, it would render campuses ultimately more equal for women and other marginalized people—it is clear that university professors need to attend more carefully to the sexual ethics of their own practice.

ABSTRACT:We extend the Base of the Pyramid (BoP) poverty-alleviation approach by recognizing the poor as valuable suppliers—specifically of intellectual property. Although the poor possess huge reserves of intellectual property, they are unable to participate in global knowledge networks owing to their illiteracy and poverty. This is a crippling form of social exclusion in today’s growing knowledge economy because it adversely affects their capabilities for advancement at several levels. Providing the poor access to global knowledge networks as rightful participants—as suppliers of (...) intellectual property—leads to poverty alleviation as a result of their increased social inclusion, not only through economic benefits, but also through the poor’s improved well-being as a result of their increased self-esteem and dignity. Using concepts from social network theory, we develop a poverty-alleviation approach to harness and integrate the intellectual property of the poor into global knowledge networks through trust-based partnerships among the poor, non-governmental organizations, and multinational corporations.

Current EEG research emphasizes gamma band coherence as a signature of functional integration, that is, the solution to the binding problem. We note that spatial patterns of coherent neural activity are also observed at other EEG frequencies. If these oscillations reflect Nunez's resonant modes, they offer a solution to the binding problem that emerges naturally from the architecture of cortical connections.

This article attempts to understand the state of teaching, training and research in business ethics in the South and South East Asian region. The countries surveyed are Bangladesh, Bhutan, Cambodia, India, Laos, Malaysia, Myanmar, Nepal, Pakistan, Sri Lanka, Thailand and Vietnam. The diversity across countries in the region is high in terms of economic development, political structuring and human development. The degree of privatization and globalization is varied across countries since each of them is in a different phase of transition. (...) In an earlier survey on Business Ethics, published in 1997, India was the only country from this region that was represented. In the current survey, 12 countries from the South and South East Asia are represented. While Business Ethics in academia is widely present, Corporate Social Responsibility, Governance and Sustainability though relatively new appear to be growing rapidly. Business Ethics courses tend to focus on functional ethics, managerial ethics and implementing codes of ethical conduct. Across the 12 countries, Business Ethics is taught either as an elective or a core course in most institutions. Training emphasis across countries is varied. While training institutions in India appear to be high, the presence of multinational consultants in Thailand, Malaysia, Bangladesh and Sri Lanka is significant. The research focus across countries in the region is weak. The high convergence on the top issues in Business Ethics, across respondents in different countries, is worthy of mention. (shrink)

Previous accounts of how people develop expertise have focused on how deliberate practice transforms the cognitive and perceptual representations and processes that give rise to expertise. However, the likelihood of developing expertise with a particular tool may also depend on the degree to which that tool fits pre‐existing perceptual and cognitive abilities. The present studies explored whether the abacus—a descendent of the first human computing devices—may have evolved to exploit general biases in human visual attention, or whether developing expertise with (...) the abacus requires learning special strategies for allocating visual attention to the abacus. To address this question, we administered a series of visual search tasks to abacus experts and subjects who had little to no abacus experience, in which search targets and distractors were overlaid atop abacus “beads.” Across three studies, we found that both experts and naïve subjects were faster to detect targets in semantically relevant components of the abacus, suggesting that abacus training is not required to exhibit attentional biases toward these components of the abacus. This finding suggests that the attentional biases that scaffold numerical processing of the abacus may emerge from general properties of visual attention that are exploited by the design of the abacus itself.

Mīmāṁsā, an Indian hermeneutics provides an exhaustive methodology to interpret Vedic statements. A formalism namely, Mīmāṁsā Inspired Representation of Actions has already been proposed in a preliminary manner. This paper expands the formalism logically and includes Syntax and Semantics covering Soundness and Completeness. Here, several interpretation techniques from Mīmāṁsā have been considered for formalising the statements. Based on these, instructions that denote actions are categorized into positive and prohibitive unconditional imperatives and conditional imperatives that enjoin reason, temporal action and goal. (...) These instructions are evaluated to three values S, V and N. If the instruction is executed with the intention of goal, then it acquires the value of S; if the intention of goal is present and the instruction is not executed, then it assumes the value of V; and if there is no intention of goal, then the instruction is evaluated to N. This formalism has also been applied in different computational settings such as AI planning, Robotics, task analysis and classification of natural language instructions. An outline of these applications and the comparison of this formalism with other relevant theories are also presented in this paper. (shrink)

Meena Srinivasan began teaching in order to touch lives, but with the demands of covering her curriculum she all but forgot her aspiration. During a retreat with Thich Nhat Hanh, Meena learned for the first time about mindfulness. In Teach, Breathe, Learn, Srinivasan highlights how mindfulness can be an effective tool in the classroom. What makes this book truly unique is Srinivasan's perspective as a classroom teacher, wrestling daily with the conditions about which she writes. Each chapter (...) begins with a personal narrative concerning a challenge Srinivasan faced during the school day and how a specific mindfulness practice helped. Testimonials from students, colleagues, and parents appear in each chapter, along with a mindfulness practice. Part 1 helps teachers develop compassion and shift from "reacting" to "responding" to demands. Part 2 offers techniques for cultivating loving-kindness and seeing students, colleagues, and parents as oneself. The author shares what research says about the effects of mindfulness practice on academic, social, and emotional learning. The last section of the book introduces the complete curriculum teachers can use to incorporate mindfulness into their classroom, replete with lesson plans, PowerPoint diagrams, handouts, and homework assignments.

It has been argued that attention and awareness might oppose each other given that attending to an adapting stimulus weakens its afterimage. We argue instead that the type of attention guided by the spread of attention and the level of processing is critical and might result in differences in awareness using afterimages. Participants performed a central task with small, large, local or global letters and a blue square as an adapting stimulus in two experiments and indicated the onset and offset (...) of the afterimage. We found that increases in the spatial spread of attention resulted in the decrease of afterimage duration. In terms of levels of processing, global processing produced larger afterimage durations with stimuli controlled for spatial extent. The results suggest that focused or distributed attention produce different effects on awareness, possibly through their differential interactions with polarity dependent and independent processes involved in the formation of color afterimages.

Research on attention has been closely linked with possible advances in the study of consciousness. Various theories and models have been proposed for attention in the past 50 years. Behavioural, computational, and neuroscientfic approaches have been successful in improving our understanding of attentional processes. Given the current status of attention research, what can we say about the relationship between attention and consciousness? This paper discusses the possible relationships between attention and consciousness. Findings from cognitive science and neuroscience relevant to the (...) elucidation of this relationship are discussed. Recent findings from phenomena that have a bearing on this relationship such as inattentional amnesia, change blindness, attentional blink, perceptual stabilization, and afterimages are described. The implications of the results of these phenomena for attention and awareness are also discussed. It is proposed that top-down attention is not a unitary phenomena and such a characterization may provide a way to interpret some of the results from these findings. (shrink)

. This paper endeavors to formalize imperatives that convey actions. Imperatives, unlike propositions, do not hold the value of true or false. Peter Vranas proposed an alternate logical formalism in the literature of imperative logic with three values, namely: Satisfaction (), Violation () and Avoidance (). Although this formalism takes into account the conditional imperatives, it does not address imperatives from the perspective of actions. According to Mīmāṁsā, the prime motive of an imperative is to carry out action so as (...) to reach the goal. This paper modifies the notion of Vranas' imperative logic using Mīmāṁsā principles. The resulting imperative formalism, focusing on action representation, is presented with syntax, deduction rules and semantic tables. The effectiveness of this representation is demonstrated in the area of artificial intelligence planning. (shrink)
