Biometrics is essentially a pattern recognition system that recognizes an individual using their unique anatomical or behavioral patterns such as face, fingerprint, iris, signature etc. Recent researches have shown that many biometric traits are vulnerable to spoof attacks. Moreover, recent works showed that, contrary to a common belief, multimodal biometric systems in parallel fusion mode can be intruded even if only one trait is spoofed. However, most of the results were obtained using simulated spoof attacks, under the assumption that the (...) spoofed and genuine samples are indistinguishable, which may not be true for all biometric traits. In addition, so far vulnerability of multimodal biometric systems in serial fusion mode against spoof attacks has not been investigated. These issues raise a demand to investigate the robustness of multimodal systems under realistic spoof attacks. In this paper, we empirically investigate the performance of serial and parallel biometric fusion modes under realistic spoof attacks. Preliminary empirical results on real biometric systems made up of face, fingerprint and iris confirm that multimodal biometric systems in both fusion modes are not intrinsically robust against spoof attacks as believed so far. In particular, multimodal biometric systems in serial fusion mode can be even less robust than systems in parallel mode. We also experimentally found that incorporating the biometric sample quality in biometric fusion increases the robustness of the multimodal systems against spoof attacks. In the end, we study the trade-off between performance and robustness of the biometric systems under spoof attacks. (shrink)

IntroductionAlthough the topic of consciousness is both mysterious and controversial, psychedelic drugs are popularly believed to provide unique insights into the nature of consciousness despite a lack of empirical evidence.MethodsThis study addresses the question of whether psychedelics change the attribution of consciousness to a range of living and non-living entities. A survey was conducted in 1,606 respondents who endorsed a belief changing psychedelic experience.ResultsParticipants rated their attributions of consciousness to a range of living and non-living entities before and after their (...) psychedelic experience. Superstitious beliefs and belief in freewill were also assessed. From before the experience to after, there were large increases in attribution of consciousness to various entities including non-human primates, quadrupeds, insects, fungi, plants, inanimate natural objects, and inanimate manmade objects. Higher ratings of mystical experience were associated with greater increases in the attribution of consciousness. Moreover, the increased attributions of consciousness did not decrease in those who completed the survey years after the psychedelic experience. In contrast to attributions of consciousness, beliefs in freewill and superstitions did not change. Notably, all findings were similar when restricted to individuals reporting on their first psychedelic experience.DiscussionThis study demonstrates that, among people who reported belief-changing psychedelic experiences, attribution of consciousness to various entities increases. Future prospective psychedelic drug administration studies that control for expectancies are needed. (shrink)

Kautilya (4th Century B.C.) is a legendary figure in India for not only writing Arthashastra, a treatise that deals extensively with the strategies for building and running a nation based on strong fundamentals of economics and the wisdom of the leader, but also for making Chandragupta Maurya the king of Magadha whose empire later on became the largest empire ever seen in the Indian history. This paper is an attempt to identify the dimensions of wise leadership to subsequently arrive at (...) a wise leadership development model for contemporary times based on the philosophy of Kautilya.

This paper identifies the different normative ethical arguments stated and suggested by Arjuna and Krishna in the Gītā , analyzes those arguments, examines the interrelations between those arguments, and demonstrates that, contrary to a common view, both Arjuna and Krishna advance ethical theories of a broad consequentialist nature. It is shown that Krishna’s ethical theory, in particular, is a distinctive kind of rule-consequentialism that takes as intrinsically valuable the twin consequences of mokṣa and lokasaṃgraha . It is also argued that (...) Krishna’s teachings in the Gītā gain in depth, coherence, and critical relevance what they lose in simplicity when the ethical theory underlying those teachings is understood as a consequentialism of this kind rather than as a deontology.

Generic sentences (e.g., bare plural sentences such as “dogs have four legs” and “mosquitoes carry malaria”) are used to talk about kinds of things. Three experiments investigated the conceptual foundations of generics as well as claims within the formal semantic approaches to generics concerning the roles of prevalence, cue validity and normalcy in licensing generics. Two classes of generic sentences that pose challenges to both the conceptually based and formal semantic approaches to generics were investigated. Striking property generics (e.g. “sharks (...) bite swimmers”) are true even though only a tiny minority of instances have the property and thus pose obvious problems for quantificational approaches, and they also do not seem to characterize kinds in terms of the principled or statistical connections investigated in previous research ( Prasada and Dillingham, 2006 ; Prasada and Dillingham, 2009). The second class — minority characteristic generics (e.g. “ducks lay eggs”) — also poses serious problems for quantificational accounts, and appears to involve principled connections even though fewer than half of its instances have the relevant property. The experiments revealed three principal discoveries: first, striking generics involve neither principled nor statistical connections. Instead, they involve a causal connection between a kind and a property. Second, minority characteristic generics exhibit the characteristics of principled connections, which suggests that principled connections license the expectation that most instances will have the property, but do not require it. Finally, the experiments also provided evidence that prevalence and the acceptability of generics may be dissociated and provided data that are problematic for normalcy approaches to generics, and for the idea that cue validity licenses low prevalence generics. As such, the studies provided evidence in favor of a conceptually based approach to the semantics of generics ( Leslie, 2007 ; Leslie, 2008; see also Carlson, 2009). (shrink)

Nominal concepts represent things as tokens of types. Recent research suggests that we represent principled connections between the type of thing something is (e.g., DOG) and some of its properties (k‐properties; e.g., having four legs for dogs) but not other properties (t‐properties; e.g., being brown for dogs). Principled connections differ from logical, statistical, and causal connections. Principled connections license (i) the expectation that tokens of the type will generally possess their k‐properties, (ii) formal explanations (i.e., explanation of the presence of (...) k‐properties in tokens of a type by reference to the type of thing it is), and (iii) normative expectations concerning the presence of k‐properties in tokens of the type. The present paper investigates the hypothesis that representing principled connections requires representing properties as aspects of being the relevant kind of thing (Aspect Hypothesis). Experiment 1 provides a direct test of the Aspect Hypothesis. Experiments 2 and 3 provide indirect tests of the Aspect Hypothesis. All three experiments provide support for the Aspect Hypothesis. Experiment 4 investigates a prediction of the Aspect Hypothesis concerning the manner in which formal explanations are licensed by principled connections. Finally, Experiment 5 investigates a prediction of the Aspect Hypothesis concerning the nature of the normative expectations licensed by principled connections. Together these results provide strong evidence for the idea that representing principled connections involves representing a property as being an aspect of being a given kind of thing. The results also help clarify the manner in which formal explanation differs from other modes of explanation. Finally, the results of the experiments are used to motivate a proposal concerning the formal structure of the conceptual representations implicated by principled connections. This structure provides a domain‐general way of structuring our concepts and embodies the perspective we take when we think and talk of things as being instances of a kind. (shrink)

Since the late 1900s the business world has been under increasing pressure to demonstrate responsible social behaviour and the pressure continues to grow. Today, the role of business in society is on the Boardroom agenda and at stake are corporate reputation, innovation, competitiveness and growth. It is a clarion call, that either, the CEO and the Board manage it or someone else will manage it for them. As we know that we cannot solve our problems with the same level of (...) thinking that created them; therefore it is imperative that we look beyond the 20th century’s scientism and materialism dominated worldly ways for solutions. In view of the above, I believe that the ‘Indian Philosophy of Consciousness’ which focuses on practicing “better-worldliness” rather than “worldliness” and has developed over the past 4000 years has the potential to help business. Better worldliness is ‘a disposition towards life that is based on a Dharmic (righteous) way of conduct; a conduct with compassion and forbearance for fellow man, no matter what the nationality, or the colour of the skin, religion or caste.’ Society expects similar compassion and forbearance from business.

The sociology of science seeks to theorize the social conditioning of science. This theorizing seems to undermine the validity of scientific knowledge and lead to relativism. Bourdieu and Latour both attempt to develop a sociology of science that overcomes relativism but stipulate opposite conditions for the production of scientific truths: while Bourdieu emphasizes autonomy, Latour emphasizes associations. This is because they work with oppositional epistemological and ontological assumptions. In both theories, the notion of truth lacks an independent definition; it is (...) derived from the theorist’s position on rationalism and defined with reference to how it is produced. This interdependence creates a different problem in each case. Bourdieu’s assertion that truths produced in relatively autonomous scientific fields are “trans-historical” remains an epistemological assertion. Latour’s argument that truths are produced through associations fails to capture the different resources, distinctions and boundarie.. (shrink)

ABSTRACT This essay examines Satyajit Ray’s children’s film Goopy Gyne Bagha Byne to interrogate the ways it signals the utopian. Contending that its utopian desire manifests through the trope of wish-fulfillment, it illuminates the trope’s centrality in the film’s imagination and articulation of freedom. Moreover, the essay suggests that the film’s utopianism is also anchored in its irrealist aesthetics. Engaging with the film’s figuration of ghosts and its violation of the narrative structure of the real, the essay illuminates how these (...) formal features inform, and are informed by, a utopian desire. Furthermore, the essay notes that despite its inherent utopianism, Goopy Gyne Bagha Byne fails to resolve some of the more obdurate social contradictions in its diegetic world, especially around questions of class, gender, and caste. Arguing that these “failures” are in keeping with its utopian spirit, I suggest they draw our attention to the imperfections of our real conditions of existence and flag the limits of textual utopianism. In so doing, they refer negatively to the social field beyond pointing to the abiding importance of class struggle as the ultimate agent of transformative social change. (shrink)

Since certain temporal aspects of the relation between duties, rights, and the interests that rights protect have not been fully theorized, a puzzle arises when we come to consider whether and how entities such as members of future generations, fetuses, deceased persons, and unconscious persons are able to possess rights. This paper evolves a unified structure for attributing the ability to possess rights to such entities. It demonstrates that while, under any cogent theory of rights-attributions, rights and duties must be (...) strictly contemporaneous, the interests that rights protect need not temporally coincide with those rights.

We simultaneously live in two worlds—our internal world of thoughts, values, desires, and experiences; and our external world in which we are born, and perform actions. Modernity, despite successfully developing our external world, has failed to develop our internal world. This has resulted in our lower nature being unleashed and a crisis of morals and values taking over society. This paper, drawing from the “science of consciousness” as detailed in the Indian tradition, looks at the nature of modernity and how (...) we can address the challenges being posed by it, by training our consciousness to higher levels.

We investigate the hypothesis that our conceptual systems provide two formally distinct ways of representing categories by investigating the manner in which lexical nominals (e.g., tree, picnic table) and phrasal nominals (e.g., black bird, birds that like rice) are interpreted. Four experiments found that lexical nominals may be mapped onto kind representations, whereas phrasal nominals map onto class representations but not kind representations. Experiment 1 found that phrasal nominals, unlike lexical nominals, are mapped onto categories whose members need not be (...) of a single kind. Experiments 2 and 3 found that categories named by lexical nominals enter into both class inclusion and kind hierarchies and thus support both class inclusion (is a) and kind specification (kind of) relations, whereas phrasal nominals map onto class representations which support only class inclusion relations. Experiment 4 showed that the two types of nominals represent hierarchical relations in different ways. Phrasal nominals (e.g., white bear) are mapped onto classes that have criteria of membership in addition to those specified by the class picked out by the head noun of the phrase (e.g., bear). In contrast, lexical nominals (e.g., polar bear) specify one way to meet the criteria specified by the more general kind concept (e.g., bear). Implications for the language–conceptual system interface, representation of hierarchical relations, lexicalization, and theories of conceptual combination are discussed. (shrink)

Five experiments provide evidence for a class of ‘dual character concepts.’ Dual character concepts characterize their members in terms of both (a) a set of concrete features and (b) the abstract values that these features serve to realize. As such, these concepts provide two bases for evaluating category members and two different criteria for category membership. Experiment 1 provides support for the notion that dual character concepts have two bases for evaluation. Experiments 2-4 explore the claim that dual character concepts (...) have two different criteria for category membership. The results show that when an object possesses the appropriate concrete features, but does not fulfill the appropriate abstract value, it is judged to be a category member in one sense but not in another. Finally, Experiment 5 uses the theory developed here to construct artificial dual character concepts and examines whether participants react to these artificial concepts in the same way as naturally occurring dual character concepts. The present studies serve to define the nature of dual character concepts and distinguish them from other types of concepts (e.g., natural kind concepts), which share some, but not all of the properties of dual character concepts. More broadly, these phenomena suggest a normative dimension in everyday conceptual representation. (shrink)

Study on the life and Hindu philosophical works of Hãsarāja Svāmī, 1805-1856, Marathi writer.

The precautionary principle justifies postponing the implementation of development projects to await better information about their environmental impacts. But if implementation capacity is congestible, as is often the case in practical settings, a postponed project may have to vie for implementation priority with projects that arrive later. Limitations of implementation capacity create two risks. First, it may sometimes not make sense to go back to a postponed project, even if it is later revealed to be a good one. Second, the (...) planner may find it worthwhile to go back to it, but at the expense of undesirable delay of subsequent projects. We consider a planner facing a sequence of projects that vary stochastically in their (1) importance and (2) improvability, but knowing that implementation capacity is congestible. The scope for congestion implies a ‘bonus’ for earlier-than-otherwise decisions, in common parlance ‘keeping the desk clear’, which works against the well-understood option value that encourages postponement. The optimal decision rule depends upon the stochastic environment whereby future projects are generated, in ways that are not obvious. The value of the bonus is increasing in the expected importance of future projects but decreasing in their expected improvability. Higher variability of the importance of projects, in the sense of mean-preserving spread, increases the size of the bonus, but variability in their improvability has a generally ambiguous impact. We characterize the adjusted decision rule and note its implications for the conduct of cost-benefit informed policy. (shrink)

Despite strong evidence of the influence of implicit theories of emotion on mental health symptoms among adult samples, scant attention has been paid to this important relation during adolesc...

Higher levels of reliance on cognitive reappraisal to manage daily emotional events are commonly associated with lower levels of depressive symptoms. However, reappraisal is a cognitively demanding regulation strategy, and its efficacy may depend on how successfully an individual is able to employ it. Individual differences in the association between reappraisal use and depressive symptoms may be particularly evident during adolescence, when the cognitive skills required to implement this complex strategy are still in development. The current study sought to determine (...) whether the association between reappraisal use and subsequent depressive symptom development is contingent on perceived regulatory success when using reappraisal. At Wave 1, adolescents (n = 178, mean age = 13.92, 49.7% female) used an experience-sampling smartphone app to report on their reappraisal use and perceptions of regulatory success over the course of two weeks. Six, 12, and 18 months later, adolescents completed a self-report measure of their depressive symptoms. Results showed that a) reappraisal use was associated with both subsequent depressive symptoms and trajectories of depressive symptoms over time, b) these associations were moderated by perceptions of regulatory success. Higher levels of reappraisal use were associated with lower levels of depressive symptoms only for those who reported higher than average between-subject regulatory success when reappraisal was enacted.

Pietraszewski's model allows understanding group dynamics through the lens of evolved coalitionary psychology. This framework is particularly relevant to understanding group dynamics on social media platforms, where coalitions based on salience of group identity are prominent and generate unique frictions. We offer testable hypotheses derived from the model that may help to shed light on social media behavior.

Van de Vliert's findings may be explained by the psychology of threat and bargaining. Poor people facing extreme threats must cope by surrendering individual freedom in service of shared group needs. Wealthier people are more able to flee from threats and/or resist authoritarianism, so their leaders must concede greater freedom. Incorporating these factors (plus inequality) can sharpen researchers' predictions.

Numerous recommendations and guidelines aim to improve the quality, timeliness and transparency of medical publications. However, these guidelines use ambiguous language that can be challenging to interpret, particularly for speakers of English as a second language. Cultural expectations within the Asia-Pacific region raise additional challenges and several studies have suggested that awareness and application of ethical publication practices in the Asia-Pacific region is relatively low compared with other regions. However, guidance on applying ethical publication practice guidelines in the Asia-Pacific region (...) is lacking. This commentary aims to improve publication practices in the Asia-Pacific region by providing guidance on applying the 10 principles of the Good Publication Practice 3 (GPP3) guidelines and the International Committee of Medical Journal Editors (ICMJE) criteria for authorship. Recommendations are provided for encore presentations, applying the ICMJE authorship criteria in the context of regional cultural expectations, and the role of study sponsors and professional medical writers. Ongoing barriers to compliance with guidelines are also highlighted, and additional guidance is provided to support authors submitting manuscripts for publication. The roles of regional journals, regulatory authorities and professional bodies in improving practices are also discussed. (shrink)

Disorders of sexual development are a heterogeneous group of disorders in which chromosomal, gonadal or anatomical sex development is atypical. The majority of these children are recognized at birth by ambiguous genitalia. Legal and societal pressures require the physician and parents to assign sex rapidly. Though sex assignment is undebated in several disorders of sexual development, many others need an individualized approach to gender-related concerns. Gender dysphoria is prevalent in disorders of sexual development, and early gender-defining surgeries have potentially lifelong (...) consequences. We use two cases, one of partial androgen insensitivity and another of simple virilizing congenital adrenal hyperplasia to illustrate that in disorders of sexual development, the ethical management principles remain the same at their core despite the vast differences in phenotypes. Sex assignment should maximize functional, psychological and sexual needs. Sex assigned should coincide with gender identity. We propose that we manage such children with the mutual participation of the physician, parents and the child. Though the parents and the physician have the child's best interests when making a decision, the child's developing autonomy should be protected. The communication of the health provider to the parent must be honest if early sex assignment is difficult. (shrink)

Kind representations, concepts like table, triangle, dog, and planet, underlie generic language. Here, we investigate the formal structure of kind representations—the structure that distinguishes kind representations from other types of representations. The present studies confirm that participants distinguish generic‐supporting properties of individuals (e.g., this watch is made of steel) and accidental properties (e.g., this watch is on the nightstand). Furthermore, work dating back to Aristotle establishes that only some generic‐supporting properties bear a principled connection to the kind, that is, are (...) true of an individual by virtue of its being a member of a specific kind (e.g., telling time for a watch). The present studies tested the hypothesis that principled connections are part of the formal structure of kind representations. Specifically, they tested whether they structure a newly learned kind representation. Experiment 1 found that introducing a property of a newly encountered novel kind in any one of four linguistic frames that provide evidence that a property has a principled connection to a kind (e.g., “It has fur because it is a blick”) led participants to infer a different conceptual consequence of principled connections (i.e., “There is something wrong with this blick, which does not have fur”) for which they had no direct evidence. Two introduction frames that provided no evidence for principled connections (e.g., “Almost all blicks have fur”) did not generate the same consequence. Experiment 2 found that all of the targeted properties were generic licensing, irrespective of the introduction frame. That the distinction between properties that bear principled connections to their kinds, and merely generic‐supporting properties structures novel kind representations, provides strong evidence that this distinction is part of the formal structure of kind representations.
