The ontological model framework for an operational theory has generated much interest in recent years. The debate concerning reality of quantum states has been made more precise in this framework. With the introduction of generalized notion of contextuality in this framework, it has been shown that completely mixed state of a qubit is preparation contextual. Interestingly, this new idea of preparation contextuality has been used to demonstrate nonlocality of some \(\psi \) -epistemic models without any use of Bell’s inequality. In (...) particular, nonlocality of a non maximally \(\psi \) -epistemic model has been demonstrated from preparation contextuality of a maximally mixed qubit and Schrödinger’s steerability of the maximally entangled state of two qubits (Leifer and Maroney, Phys Rev Lett 110:120401, 2013). In this paper, we, show that any mixed state is preparation contextual. We, then, show that nonlocality of any bipartite pure entangled state, with Schmidt rank two, follows from preparation contextuality and steerability provided we impose certain condition on the epistemicity of the underlying ontological model. More interestingly, if the pure entangled state is of Schmidt rank greater than two, its nonlocality follows without any further condition on the epistemicity. Thus our result establishes a stronger connection between nonlocality and preparation contextuality by revealing nonlocality of any bipartite pure entangled states without any use of Bell-type inequality.

Sibajiban Bhattacharyya, Indian philosopher; contributed articles.

Although the following essay does not strictly fall within the discipline of classical Indian philosophy, in which our Journal specializes, we publish it here for two reasons: (1) K. C. Bhattacharya was an outstanding philosopher of India in the past generation, and his thought was deeply influenced by his thorough study of classical Indian Vedanta and Jainism, as well as by the study of Kant (four of our consulting editors were his direct students). (2) His view about the notion (...) of the speakable and philosophy is unique, and it has remained opaque to most of us. Hence some discussion will be illuminating. (shrink)

Creativity is the hallmark of human cognition, yet scientific understanding of creative processes is limited. However, there is increasing interest in revealing the neural correlates of human creativity. Though many of these studies, pioneering in nature, help demystification of creativity, but the field is still dominated by popular beliefs in associating creativity with "right brain thinking", "divergent thinking", "altered states" and so on (Dietrich and Kanso, 2010). In this article, we discuss a computational framework for creativity based on Baars' global (...) workspace theory (Baars, 1988) enhanced with mechanisms based on information theory. Next we propose a neurocognitive architecture of creativity with a strong focus on various facets (i.e., unconscious thought theory, mind wandering, spontaneous brain states) of un/pre-conscious brain responses. Our principal argument is that pre-conscious creativity happens prior to conscious creativity happens prior to conscious creativity and the proposed computational model may provide a mechanism by which this transition is managed. This integrative approach, albeit unconventional, will hopefully stimulate future neuroscientific studies of the inscrutable phenomenon of creativity. (shrink)

It is widely recognized that conceptual and theoretical innovations and the employment of new instruments and experimental techniques are important factors in explaining the growth of scientific knowledge in chemistry. This study examines another dimension of research in chemistry, collaboration and co-authorship. I focus specifically on Theodore Richards’ career and publications. During the period in which Richards worked, co-authorship was beginning to become more common than it had been previously. Richards was the first American chemist to be awarded a Nobel (...) Prize and he was at the forefront in this new trend in chemistry. He collaborated more than was typical for his time, with many scientists, in different sized groups, and he often had persistent collaborative relationships, extending over a number of years. Further, it appears that these collaborations benefited Richards, his collaborators, and the field of chemistry as a whole. (shrink)

Due to the highly visible nature of the disease, smallpox received a lot of attention from the colonial and independent Indian governments. An assessment of the changing official views about the impact of geographical and environmental factors on modes of variola causation and control presents insights into themes that are generally ignored in the existing historiography. Rather than being synchronised efforts, imposed top-down, provincial level officials in charge of running vaccination programmes were able to retain a great degree of autonomy (...) and shape the nature of local immunisation drive. As a result, vaccination work in the country was often disjointed, marked by official disagreements about the usefulness of certain strategies and technological inputs, with these trends being most noticeable in rural areas. Thus, this study seeks to highlight the importance of recognising — and studying — the fractured nature of medical and public health administration in the South Asian sub-continent. (shrink)

Samkhya is one of the oldest, if not the oldest, system of classical Indian philosophy. This book traces its history from the third or fourth century B. C. up through the twentieth century. The Encyclopedia as a whole will present the substance of the various Indian systems of thought to philosophers unable to read the Sanskrit and having difficulty in finding their way about in the translations (where such exist). This volume includes a lengthy introduction by Gerald James Larson, which (...) discusses the history of Samkhya and its philosophical contours overall. The remainder of the book includes summaries in English of all extant Sanskrit texts of the system. Originally published in 1987. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This paper examines how employees react to their organizations’ corporate social responsibility initiatives. Drawing upon research in internal marketing and psychological contract theories, we argue that employees have multi-faceted job needs and that CSR programs comprise an important means to fulfill developmental and ideological job needs. Based on cluster analysis, we identify three heterogeneous employee segments, Idealists, Enthusiasts, and Indifferents, who vary in their multi-faceted job needs and, consequently, their demand for organizational CSR. We further find that an organization’s CSR (...) programs generate favorable employee-related outcomes, such as job satisfaction and reduction in turnover intention, by fulfilling employees’ ideological and developmental job needs. Finally, we find that CSR proximity strengthens the positive impact of CSR on employee-related outcomes. This research reveals significant employee heterogeneity in their demand for organizational CSR and sheds new light on the underlying mechanisms linking CSR to employee-related outcomes. (shrink)

“Doğal din” terimi, bazen doğanın kendisinin ilahi olduğu bir panteistik doktrine atıfta bulunur. “Doğal teoloji” terimi ise aksine, başlangıçta gözlemlenen doğal gerçekler temelinde (ve bazen) Tanrı’nın varlığını savunmaya yönelik projeye atıfta bulunur. Bununla birlikte çağdaş felsefede, hem “doğal din” hem de “doğal teoloji” genel olarak, dinî veya teolojik konuları araştırmak için insana, “doğal” olan bilişsel yetilerini – akıl, algı, içgözlem- kullanma projesini ifade eder. Doğal din veya teoloji, mevcut anlayış üzerine, doğayla ilgili ampirik araştırmalarla sınırlı olmamakla birlikte ayrıca panteistik bir (...) sonuçla da bağlantılı değildir. Bununla birlikte o, özel doğal olmayan yetilere (ESP, telepati, mistik deneyim) veya doğaüstü bilgi kaynaklarına (kutsal metinler, vahiy teolojisi, inanç otoriteleri, doğrudan doğaüstü iletişim) hitap etmekten kaçınır. Genel olarak, doğal din veya teoloji (bundan böyle “doğal teoloji” olarak anılacaktır), diğer felsefi ve bilimsel girişimlerle aynı rasyonel inceleme standartlarına uymayı amaçlamaktadır ve aynı değerlendirme ve eleştiri yöntemlerine tabidir.

This paper discusses the utilization of pilots' physiological indications such as electroencephalographic signals, ocular parameters, and pilot performance-based quantitative metrics to estimate cognitive workload. The study aims to derive a non-invasive technique to estimate pilot's cognitive workload and study their correlation with standard physiological parameters. Initially, we conducted a set of user trials using well-established psychometric tests for evaluating the effectiveness of pupil and gaze-based ocular metrics for estimating cognitive workload at different levels of task difficulty and lighting conditions. Later, (...) we conducted user trials with the NALSim flight simulator using a business class Learjet aircraft model. We analyzed participants' ocular parameters, power levels of different EEG frequency bands, and flight parameters for estimating variations in cognitive workload. Results indicate that introduction of secondary task increases pilot's cognitive workload significantly. The beta frequency band of EEG, nearest neighborhood index specifying distribution of gaze fixation, L1 Norm of power spectral density of pupil diameter, and the duty cycle metric indicated variations in cognitive workload.

Government lockdowns, school closures, mass unemployment, health and wealth inequality. Political Philosophy in a Pandemic asks us, where do we go from here? What are the ethics of our response to a radically changed, even more unequal society, and how do we seize the moment for enduring change? Addressing the moral and political implications of pandemic response from states and societies worldwide, the 20 essays collected here cover the most pressing debates relating to the biggest public health crisis in the (...) last century. Discussing the pandemic in five key parts covering social welfare, economic justice, democratic relations, speech and misinformation, and the relationship between justice and crisis, this book reflects the fruitful combination of political theory and philosophy in laying the theoretical and practical foundations for justice in the long-term.

Kadınların mukaddes görevlerini, insan neslinin devamlılığını sağlamayı yerine getirebilmelerine imkân veren aylık kanama dönemlerinin ironik bir şekilde kirlilik sebebi sayılması kadim bir anlayıştır. Her ne kadar feminist akımlarla beşeriyet tarihinin başlangıcındaki anaerkil dönemde kadınlara kutsallık katan doğurganlıklarının bir uzantısı olan adet görmelerinin, ataerkil düzene geçişle bir aşağılanma ve murdarlık sebebi sayılmaya başlandığı iddia edilmişse de bu görüş temellendirilebilir değildir. Tarihi süreçte kadınların regl dönemlerindeyken bereket ve şifa kaynağı görüldüklerinin de etrafına pislik bulaştıran bir murdarlık halinde kabul edildiklerinin de örnekleri bulunmak (...) mümkündür. Bununla birlikte hayızlı kadını kirli kabul eden anlayışın daha yaygın olduğu söylenebilir. Özellikle bu güne ulaşan şekliyle Yahudilikte, Cennette işlediği ilk günah sebebiyle cezalandırılmasının sonucu olarak adet gördüğü kabul edilen kadın, manen pistir. Bu pisliği dokunduğu her şeye bulaştırdığından tecrit edilmelidir. Kanaması bittiğinde temizlenmesi özel ritüellerle sağlanabilir. Zaten Yahudilikte kirlilik sebepleri ve kirliliğin toplumda yaygınlaşmaması için alınması gereken tedbirler konusu etrafındaki ahkâm, geniş ve karmaşıktır. Cüzzam hastalığına yakalanmakta kirlilik sebeplerindendir ve cüzzamlı da, özellikle din adamlarından, tecrit edilmelidir. Güncel Hristiyanlık, Yahudiliğin hayızlı kadınla ilgili düzenlemelerinin neredeyse uygulanamaz yükünden hepsini yok sayarak kurtulmuşsa da, ontolojik açıdan kadını ilk günahtan sorumlu tutma anlayışını genel olarak devam ettirmektedir. Cüzzamlıysa Hz. İsa (as) aracılığıyla tedavi edilerek Tanrı'nın rahmetinin ulaştığı bir konuma gelmiştir. İslam dini ise ilk günahı işlemede kadına ayrı bir sorumluluk yüklemediği gibi adet dönemini de bir kirlilik sebebi saymaz. Hz. Muhammed (as), hayızlı kadın hakkında indirilen ayetteki ifadeleri açıklarken, kadınları kirli kabul edip tecrit etmenin yanlış bir yorum olduğunu vurgulamıştır. Aksine bu dönemdeki kadınların temiz oldukları hakikatini hem sözleriyle hem de uygulamalarıyla göstermiştir. Sünnete uygun davranışın adetli eşle, tam bir cinsel birliktelik hariç, ilişkinin devam ettirilmesi olduğunu açığa çıkaran rivayetler çok sayıdadır. Öncellikle konuya ilk elden vakıf olan müminlerin annelerinden ve diğer sahabeden Hz. Peygamber'in hayızlı eşiyle aynı yatak ve yorganı kullanmaya, birlikte yiyip içmeye devam ettiğini; hayızlı kadının elinin, kan bulaşmadıkça giydiklerinin, tükürüğünün temiz olduğunu açıklayan bilgiler aktarılmaktadır. Yine de konu etrafındaki tartışma ve yanlış uygulamalar tabiîn döneminde devam etmiştir. Kadim inançların değişiminin zorluğu bu örnekte de açığa çıkmaktadır. Ayrıca kadınların aybaşı hali İslamî literatürde çoğunlukla fıkhi açıdan ele alınmıştır. Zira kadınların bu dönemde bulunması ibadetler ve muamelat açısından sonuçlar doğurmaktadır. Bu arada kadınla ilgili kökleri yaratılış anlatısına giden ontolojik suçluluğu ve cezayı hak ettiği inanışlarının Hz. Peygamber'in sünnetiyle ret edilmesinin önemi dikkatten kaçmaktadır. Kur'an'ın deyimiyle eza çeken kadına muhabbet ve ilgi gösterip desteklemenin sünnette vurgulanması da meselenin ihmal edilen bir yönüdür. Oysaki nasıl cüzzamlı Hz. İsa aracılığıyla uzak durulması gereken murdarlıktan Allah'ın bir peygamberi aracılığıyla şifa ulaştırılmasına layık kulu konumuna geldiyse, hayızlı kadın da Hz. Muhammed'in sünnetindeki uygulamayla birlikte yaşanacak manen temiz kişi konumuna getirilmiştir. (shrink)

Modal ontolojik argüman, Tanrı’nın varlığını sadece bilfiil gerçek olan bu dünyada değil, bütün mümkün dünyalarda göstermeye yönelik bir argümandır. Anselm’in (1033-1109) Proslogion adlı eserinin 3. bölümünde “kendisinden daha büyüğü düşünülemeyen” şeklinde tanımlanan; Tanrı’nın var olmamasının da düşünülemeyeceğini, bu yüzden de varolmamasının imkansızlığı üzerinde kurulu yeni bir argüman bulunduğunu öne süren bazı araştırmacılar, bu argümanı mümkün dünyalar semantiği yardımıyla formüle edip, “modal ontolojik argüman” şeklinde adlandırmışlardır. Çok farklı şekillerde formüle edilmiş bu argüman kabaca Tanrı’nın mümkünse zorunlu olması, dolayısıyla bilfiil gerçek olan (...) bu dünyada da var olması gerektiğini savunur. (shrink)
