Due to the complexity and versatility of network security alarm data, a cloud-based network security data extraction method is proposed to address the inability to effectively understand the network security situation. The information properties of the situation are generated by creating a set of spatial characteristics classification of network security knowledge, which is then used to analyze and optimize the processing of hybrid network security situation information using cloud computing technology and co-filtering technology. Knowledge and information about the security situation (...) of a hybrid network has been analyzed using cloud computing strategy. The simulation results show that a cyber security crash occurs in window 20, after which the protection index drops to window 500. The increase in the security index of 500 windows is consistent with the effectiveness of the concept of this document method, indicating that this document method can sense changes in the network security situation. Starting from the first attacked window, the defense index began to decrease. In order to simulate the added network defense, the network security events in the 295th time window were reduced in the original data, and the defense index increased significantly in the corresponding time period, which is consistent with the method perception results, which further verifies the effectiveness and reliability of this method on the network security event perception. This method provides high-precision knowledge of network security situations and improves the security and stability of cloud-based networks. (shrink)

Bortolotti’s Delusions and Other Irrational Beliefs defends the view that delusions are beliefs on a continuum with other beliefs. A different view is that delusions are more like illusions, that is, they arise from faulty perception. This view, which is not targeted by the book, makes it easier to explain why delusions are so alien and disabling but needs to appeal to forensic aspects of functioning.

Providing medical care and planning for a procedure such as amputation may have different cultural contexts, based on patients’ country, comfort, and contract with their physician. These contexts may create complexities for physicians as they interact with patients and caregiving relatives. Issues such as the personal choices of a caregiving relative may appear to unduly influence the decisions behind complex healthcare choices. We consider several possible scenarios in the background of the complex case presented in “Family Loyalty as a Cultural (...) Obstacle to Good Care: The Case of Mrs. Indira,” in this issue of JCE.

This book seeks to provide an introductory outline of the history and theory of knowledge production, notwithstanding the vastness of the subject. It is a brief history of intellectual formation or history of ideas. One can see it as a textbook of historical epistemology, which in spatio-temporal terms historicises knowledge production and contextualises methodological development. It addresses the historical process of the social constitution of knowledge, that is, the social history of the making of knowledge.

Discipline based approach to knowledge and specialization goes back to the classical Graeco-Roman times. It was Isaac Newton’s Principia, which represented academic perfection of Renaissance inquiry, criticism, creativity and theorization. Principia set the epochal model of knowledge and led to the making of the Age of Enlightenment and the Age of Reason. August Comte heralded an era of Positivism in academic research and prepared the ground for the making of disciplines. As new knowledge accrued over centuries, specialization got diversified at (...) the expense of holistic understanding. Academics of disciplinary specialization sought to resolve the problem through multidisciplinary research. Inherently discipline centric, it got further distanced from social reality. Interdisciplinary approach began as a movement through convergence research aiming to restore holistic comprehension and draw knowledge closer to social reality. It is production of knowledge beyond disciplines and across their interfaces enabling research output to be regenerative, non-conventional and resolution oriented. (shrink)

BackgroundConventionally, transcranial direct current stimulation (tDCS) aims to focalize the current reaching the target region-of-interest (ROI). The focality can be quantified by the dose-target-determination-index (DTDI). Despite having a uniform tDCS setup, some individuals receive focal stimulation (high DTDI) while others show reduced focality (“non-focal”). The volume of cerebrospinal fluid (CSF), gray matter (GM), and white matter (WM) underlying each ROI govern the tDCS current distribution inside the brain, thereby regulating focality.AimTo determine the regional volume parameters that differentiate the focal and (...) non-focal groups.MethodsT1-weighted images of the brain from 300 age-sex matched adults were divided into three equal groups- (a) Young (20 ≤ × < 40 years), (b) Middle (40 ≤ × < 60 years), and (c) Older (60 ≤ × < 80 years). For each group, inter and intra-hemispheric montages with electrodes at (1) F3 and right supraorbital region (F3-RSO), and (2) CP5 and Cz (CP5-Cz) were simulated, targeting the left- Dorsolateral Prefrontal Cortex (DLPFC) and -Inferior Parietal Lobule (IPL), respectively. Both montages were simulated for two current doses (1 and 2 mA). For each individual head simulated for a tDCS configuration (montage and dose), the current density at each region-of-interest (ROI) and their DTDI were calculated. The individuals were categorized into two groups- (1) Focal (DTDI ≥ 0.75), and (2) Non-focal (DTDI < 0.75). The regional volume of CSF, GM, and WM of all the ROIs was determined. For each tDCS configuration and ROI, three 3-way analysis of variance was performed considering- (i) GM, (ii) WM, and (iii) CSF as the dependent variable (DV). The age group, sex, and focality group were the between-subject factors. For a given ROI, if any of the 3 DV’s showed a significant main effect or interaction involving the focality group, then that ROI was classified as a “focal ROI.”ResultsRegional CSF was the principal determinant of focality. For interhemispheric F3-RSO montage, interaction effect (p < 0.05) of age and focality was observed at Left Caudate Nucleus, with the focal group exhibiting higher CSF volume. The CSF volume of focal ROI correlated positively (r ∼ 0.16, p < 0.05) with the current density at the target ROI (DLPFC). For intrahemispheric CP5-Cz montage, a significant (p < 0.05) main effect was observed at the left pre- and post-central gyrus, with the focal group showing lower CSF volume. The CSF volume correlated negatively (r ∼ –0.16, p < 0.05) with current density at left IPL. The results were consistent for both current doses.ConclusionThe CSF channels the flow of tDCS current between electrodes with focal ROIs acting like reservoirs of current. The position of focal ROI in the channel determines the stimulation intensity at the target ROI. For focal stimulation in interhemispheric F3-RSO, the proximity of focal ROI reserves the current density at the target ROI (DLPFC). In contrast, for intrahemispheric montage (CP5-Cz), the far-end location of focal ROI reduces the current density at the target (IPL). (shrink)

Extensive empirical work has examined ethical perceptions of different occupational groups in marketing. Additionally, researchers have explored ethical apperceptions of industrial customers and retail consumers. Minimal effort, though, has been directed at investigating differences in ethical perceptions between buyers and sellers, notwithstanding considerable theoretical arguments for doing so. This paper reports the results of a study that focused on differences between retail customers’ and retail salespeople’s perceptions of questionable buying and selling behaviors. Findings indicate that the two groups differ in (...) some respect depending on which group is engaging in the questionable conduct. Managerial and future research implications are provided.

Nele busco evidenciar a idéia de que as concepções do pintor russo, em grande parte construída em consonância com o pensamento esotérico do fim do século XIX, aproximam-se bastante de um tipo de cosmologia mágica, que abriga uma perspectiva análoga àquela das categorias do pensamento mágico segundo Marcel Mauss. No centro desta cosmologia encontra-se a arte, síntese do Espiritual, cuja noção central é a de gênio (...) que creio ser herdada em grande medida de Kant. (shrink)

This is a collection of three studies of both retrospective and prospective significance for the author s preoccupation with the philosophical problems arising out of the transcendentalist orientation. The aim of the present work is to focus on the notion of the paradoxical alliance of unity and difference of the transcendentalist ego and the human subject. To think this notion through in terms of its implications and consequences and to rethink the nature and method of philosophy, its relation to language (...) and to the sciences, is what the author means by the humanization of transcendental philosophy.The first study addresses the genesis of the problematic of humanization in Husserl s phenomenology of the life-world; the second seeks to understand the presuppositions and consequences of Heidegger s transformation of phenomenology into fundamental ontology; and the third takes up the themes explored by Husserl and Heidegger as they enter into Merleau-Ponty s thought. In the Epilogue, the author seeks to balance the logocentrism of phenomenology with the biocentrism of a philosophy of life.The late R. Sundara Rajan was Professor of Philosophy at the University of Poona, Pune, Fellow at the Indian Institute of Advanced Study, Shimla, and Senior Fellow at the Indian Council of Philosophical Research, New Delhi, India.

Robustness arguments hold that hypotheses are more likely to be true when they are confirmed by diverse kinds of evidence. Robustness arguments require the confirming evidence to be independent. We identify two kinds of independence appealed to in robustness arguments: ontic independence —when the multiple lines of evidence depend on different materials, assumptions, or theories—and probabilistic independence. Many assume that OI is sufficient for a robustness argument to be warranted. However, we argue that, as typically construed, OI is not a (...) sufficient independence condition for warranting robustness arguments. We show that OI evidence can collectively confirm a hypothesis to a lower degree than individual lines of evidence, contrary to the standard assumption undergirding usual robustness arguments. We employ Bayesian networks to represent the ideal empirical scenario for a robustness argument and a variety of ways in which empirical scenarios can fall short of this ideal. (shrink)

The core of the work is a lengthy hermeneutically-oriented discussion of political judgment, which projects the notion of political competence as a language mediated capacity of human subjects to recognize the common good by way of discourse. This discursive conception of the political which is mediated on the one hand by a relationship to the moral and on the other to the conception which can be contrasted with the modern paradigm of politics as the episteme of power relations. The earlier (...) chapters build up to this contrast of the classical and the contemporary paradigms and stake out a claim for the primacy of the political in the classical mould. The work is a return to the classical idea of the political by way of a long detour via the theory of judgment, the Kuhnian theory of paradigms, Ricoeur's theory of textual hermeneutics and rhetorical theory. Ranging from discussions of sociological and political theory to philosophy of language and philosophical logic, the work seeks to connect the Aristotelian-Kautilyan conception of the political to contemporary debates in the metatheory of the social sciences.

For Knox, ‘spacetime’ is to be defined functionally, as that which picks out a structure of local inertial frames. Assuming that Knox is motivated to construct this functional definition of spacetime on the grounds that it appears to identify that structure which plays theoperationalrole of spacetime—i.e., that structure which is actually surveyed by physical rods and clocks built from matter fields—we identify in this paper important limitations of her approach: these limitations are based upon the fact that there is a (...) gap between inertial frame structure and that which is operationally significant in the above sense. We present five concrete cases in which these two notions come apart, before considering various ways in which Knox’s spacetime functionalism might be amended in light of these issues. (shrink)

The value-free ideal for science holds that values should not influence the core features of scientific reasoning. We defend the difference-to-inference model of value-permeation, which holds that value-permeation in science is problematic when values make a difference to the inferences made about a hypothesis. This view of value-permeation is superior to existing views, and it suggests a corresponding maxim—namely, that scientists should strive to eliminate differences to inference. This maxim is the basis of a novel value-free ideal for science. -/- (...) . (shrink)

Noncommutative geometries generalize standard smooth geometries, parametrizing the noncommutativity of dimensions with a fundamental quantity with the dimensions of area. The question arises then of whether the concept of a region smaller than the scale—and ultimately the concept of a point—makes sense in such a theory. We argue that it does not, in two interrelated ways. In the context of Connes’ spectral triple approach, we show that arbitrarily small regions are not definable in the formal sense. While in the scalar (...) field Moyal–Weyl approach, we show that they cannot be given an operational definition. We conclude that points do not exist in such geometries. We therefore investigate (a) the metaphysics of such a geometry, and (b) how the appearance of smooth manifold might be recovered as an approximation to a fundamental noncommutative geometry.

The rapid advancement of algorithmic trading has demonstrated the success of AI automation, as well as gaps in our understanding of the implications of this technology proliferation. We explore ethical issues in the context of autonomous trading agents, both to address problems in this domain and as a case study for regulating autonomous agents more generally. We argue that increasingly competent trading agents will be capable of initiative at wider levels, necessitating clarification of ethical and legal boundaries, and corresponding development (...) of norms and enforcement capability.

The attributes and representative spirit of a culture, era, or community, as manifested in its attitude and aspiration, hold the concept of ethos. Likewise, every civilization has its own unique ethos; however, at present, it is shared through multiple globalized dynamics such as—media, technology, and other connectivities. The communication gaps have been filled with unique mediums; people are more open to new things, and comforts have increased dramatically. Nevertheless, despite such liberal and contemporary facts, we have encountered several problems and (...) value degradation in every aspect of human life. Service and leadership, art and aesthetics, ethics and morality, politics and society, science and law, and many other realms of human endeavour have been filled with much more complexity and crisis than before. It provokes intellectuals to rethink contemporary civilization and inspires the present critical research on top. Practically surrounded by all such challenges and selecting a few of them, this paper aims to address the complexities and stepping stones in the path of leadership, holistic ethics, and human well-being from philosophical perspectives while presenting a dystopian picture of contemporary reality and continuously following the critical method. Additionally, the conclusion and uniqueness of this paper locate within the fundamental questions raised in the present composition regarding the above-selected themes and an emphasis on the renaissance of inclusive ethics and virtuous leadership.

The value-free ideal in science has been criticised as both unattainable and undesirable. We argue that it can be defended as a practical principle guiding scientific research even if the unattainability and undesirability of a value-free end-state are granted. If a goal is unattainable, then one can separate the desirability of accomplishing the goal from the desirability of pursuing it. We articulate a novel value-free ideal, which holds that scientists should act as if science should be value-free, and we argue (...) that even if a purely value-free science is undesirable, this value-free ideal is desirable to pursue.

Phase transitions are an important instance of putatively emergent behavior. Unlike many things claimed emergent by philosophers, the alleged emergence of phase transitions stems from both philosophical and scientific arguments. Here we focus on the case for emergence built from physics, in particular, arguments based upon the infinite idealization invoked in the statistical mechanical treatment of phase transitions. After teasing apart several challenges, we defend the idea that phase transitions are best thought of as conceptually novel, but not ontologically or (...) explanatorily irreducible to finite physics; indeed, by looking at ongoing work on “smooth phase transitions” we even suggest that they’re not even conceptually novel. In the case of renormalization group theory, consideration of infinite systems and their singular behavior provides a central theoretical tool, but this is compatible with an explanatory reduction. Phase transitions may be “emergent” in some sense of this protean term, but not in a sense that is incompatible with the reductionist project broadly construed. (shrink)

A remarkable but little commented on feature of the various discourses on India circulating today is the near total absence of its metaphysical heritage as a source of illumination into our contemporary condition. On the few occasions that this heritage is explicitly invoked, it is either as a subsidiary aspect of some purportedly larger concept such as religion, civilization, history, tradition etc., or as a set of quaint speculations fit for study as a tertiary branch of history of philosophy or (...) religion but with little claim to political relevance. But is this neglect as innocent as it appears? Or might it be that the metaphysical heritage confronts us with the disavowed -- indeed the unthinkable that lurks behind our current obsessions: progress and development; modernity and tradition; faith and secularism; history and myth; fundamentalism and tolerance? The central claim of this book is that the metaphysical heritage has an autonomy and dignity of its own not subsumable under any other concept whatsoever; and that furthermore, our national self-understanding and its place in the current system of global knowledge are founded on a wholesale effacing of this heritage. The collective contention of the papers in this volume is that a full and proper understanding of our ever lengthening catalogue of social afflictions and pathologies demands that we squarely confront the consequences of this fateful evasion, no matter how unsettling it might be to our vaunted notions about ourselves. Only in and out of such a self-encounter can we hope to break out of our thralldom to the currently hegemonic vision of humanitys future -- a vision that is already bankrupt in every respect, but which nonetheless seems able to reproduce itself without end.

Brown and Pooley’s ‘dynamical approach’ to physical theories asserts, in opposition to the orthodox position on physical geometry, that facts about physical geometry are grounded in, or explained by, facts about dynamical fields, not the other way round. John Norton has claimed that the proponent of the dynamical approach is illicitly committed to spatiotemporal presumptions in ‘constructing’ space-time from facts about dynamical symmetries. In this article, I present an abstract, algebraic formulation of field theories and demonstrate that the proponent of (...) the dynamical approach is not committed, in special relativity, to the illicit presumptions to which Norton refers.

Supersymmetry (SUSY) is a proposed symmetry between bosons and fermions. The structure of the space of SUSY generators is such that the distinction between internal and spacetime symmetries is blurred. As a result, there are two viable candidates for the correct spacetime setting for a flat supersymmetric field theory---Minkowski spacetime and superspace. an extension of four- dimensional Minkowski spacetime to include (at least) four new dimensions, coordinatised by mathematical objects known as supernumbers. These objects are, in one significant way, quite (...) different from real or complex number---some of them have the property that their order of multiplication makes a difference; in mathematical terms, they are said to have nontrivial commutation properties. This paper argues for two theses: first, that one standard set of arguments, related to universality of symmetry behaviour, that motivate a particular choice of spacetime structure in familiar spacetime theories motivates the choice of superspace as the appropriate spacetime for SUSY field theories. And second, that the metaphysical utility of the concept of spacetime requires more than just the satisfaction of this universality condition; in supersymmetric theories, the spacetime concept is not as useful as in special relativity.

Recent work in the physics literature demonstrates that, in particular classes of rotating spacetimes, physical light rays in general do not traverse null geodesics.

The Saga of Dharmapuri by O.V. Vijayan is a dystopian fantasy set in the imaginary country of Dharmapuri, which could be a depiction of India or any other newly independent country in the post-colonial era. Mikhail Bakhtin in his treatise Rabelais and his World justifies the use of Grotesque Realism, a literary trope that allows the author to move away from the conventions of propriety and decency to convey messages that are real and powerful nevertheless. Usually exaggeration and hyperbole are (...) key elements of this style. Through the centuries, literature has often been a medium through which contemporary concerns have been transmitted. This paper argues that O.V. Vijayan uses Grotesque Realism in his novel to depict the political, social and economic condition of India of the 1970s- specifically a country that was under emergency. Like all dystopian fables, The Saga of Dharmapuri has been prophetic in anticipating some of the social issues that we face even today. The paper aims at examining how Vijayan uses explicit language and scatological and sexual imagery so as to achieve this sense of realism within his novel. (shrink)

If we cannot directly empirically test the claims of particular scientific theory, then it would be nice to have some other criteria with which to assess its viability. In his 2013 book, String Theory and the Scientific Method, Richard Dawid aims to develop such criteria, with an eye to vindicating research programs in disciplines where direct empirical data is scant or non-existent. In an accompanying paper, Dawid, Hartmann and Sprenger formalise Dawid’s so-called ‘No Alternatives Argument’ using a generalised Bayesian framework, (...) as a first step towards formalising Dawid’s entire re- search programme. In this paper, I argue that the formalisation of the NAA cannot play the central role in Dawid’s programme as intended. This is based on the observation that not all confirmation is non-negligible confirmation. For Dawid’s programme to be useful, it must demonstrate the viability not just of non-empirical theory confirmation, but of non-negligible non-empirical theory confirmation. I argue that Dawid et al.’s appeal to Bayesian confirmation theory to formalise his NAA cannot guarantee non-negligible confirmation. As a result, I conclude that if Dawid’s overall project is to succeed, it must do so without the NAA formalised in this way. (shrink)

Therapeutic privilege is a defence that may be available to doctors who fail to disclose to the patient relevant information when seeking informed consent for treatment if they have a reasonable belief that providing that information would likely cause the patient concerned serious physical or mental harm. In a landmark judgement, the Singapore Court of Appeal introduced a novel interpretation of TP, identifying circumstances in which it might be used with patients who did not strictly lack capacity but might be (...) inclined to refuse recommended treatments. In this paper, we explore the conceptual and practical challenges of this novel interpretation of TP. We propose that more emphasis should be placed on forms of shared and supported decision-making that foster the autonomy of patients with compromised mental capacity while being mindful of the need to safeguard their well-being. The kind of privilege that doctors might need to invoke is one of time and supportive expertise to ensure a flexible, responsive approach calibrated to the individual patients’ needs. The provision of such service would extinguish the need for the novel TP proposed by the Singapore Court of Appeal. (shrink)
