In this paper, we employ bibliometric analysis to empirically analyse the research on social entrepreneurship published between 1996 and 2017. By employing methods of citation analysis, document co-citation analysis, and social network analysis, we analyse 1296 papers containing 74,237 cited references and uncover the structure, or intellectual base, of research on social entrepreneurship. We identify nine distinct clusters of social entrepreneurship research that depict the intellectual structure of the field. The results provide an overall perspective of the social entrepreneurship field, (...) identifying its influential works and analysing scholarly communication between these works. The results further aid in clarifying the overall centrality features of the social entrepreneurship research network. We also examine the integration of ethics into social entrepreneurship literature. We conclude with a discussion on the structure and evolution of the social entrepreneurship field. (shrink)

In this study, we employed a combination of bibliometric analysis and a structured review approach to examine the social entrepreneurship (SE) research. Our bibliometric analysis involved 2517 articles containing 155,846 references and we analyzed the data in three time periods: 1990–2009, 2010–2014, and 2015–2020 to detect longitudinal trends. This analysis helped us to identify the intellectual foundation of each period and the evolution of the intellectual structure of SE research. We specifically identified 13, 9, and 11 clusters that constituted the (...) philosophical foundations of SE research for the periods 1990–2009, 2010–2014, and 2015–2020 respectively. A longitudinal comparison of three periods helped us to trace the evolution of the intellectual structure of SE research. Further, the structured review, involving 106 recent influential articles, enabled us to identify 10 recent dominant themes of SE research. Building on our bibliometric and structured review approach, we developed an organizing framework for guiding future SE research across six dimensions: ethics, individual, community, collaborative, organizational, and contextual.

The aim of this article was to discuss the modeling and control method of quadrotor unmanned aerial vehicle. In the process of modeling, mechanism modeling and experimental testing are combined, especially the motor and propeller are modeled in detail. Through the understanding of the body structure and flight principle of the quadrotor UAV, the Newton–Euler method is used to analyze the dynamics of the quadrotor UAV, and the mathematical model of the UAV is established under the small angle rotation. Process (...) identifier is used to control it. First, the attitude angle of the model is controlled by PID, and based on this, the speed in each direction is controlled by PID. Then, the PID control of the four rotor aircraft with the center of gravity offset is simulated by MATLAB. The results show that the pitch angle and roll angle can be controlled by 5 degrees together without center of gravity deviation, and the PID can effectively control the control quantity and achieve the desired effect in a short time. Classical BP algorithm, classical GA-BP algorithm, and improved GA-BP algorithm were trained, respectively, with a total of 150 sets of training data, training function uses Levenberg-Marquardt, and performance function uses mean squared error. In the background of the same noise, the improved GA-BP algorithm has the highest detection rate, classical GA-BP algorithm is the second, and classical BP algorithm is the worst. The simulation results show that the PID control law can effectively control the attitude angle and speed of the rotor UAV in the case of center of gravity deviation. (shrink)

The QR code recognition often faces the challenges of uneven background fluctuations, inadequate illuminations, and distortions due to the improper image acquisition method. This makes the identification of QR codes difficult, and therefore, to deal with this problem, artificial intelligence-based systems came into existence. To improve the recognition rate of QR image codes, this article adopts an improved adaptive median filter algorithm and a QR code distortion correction method based on backpropagation (BP) neural networks. This combination of artificial intelligence algorithms (...) is capable of fitting the distorted QR image into the geometric deformation pattern, and QR code recognition is accomplished. The two-dimensional code distortion is addressed in this study, which was a serious research issue in the existing software systems. The research outcomes obtained after emphasizing on the preprocessing stage of the image revealed that a significant improvement of 14% is observed for the reading rate of QR image code, after processing by the system algorithm in this article. The artificial intelligence algorithm adopted has a certain effect in improving the recognition rate of the two-dimensional code image. (shrink)

The dependency of a speech recognition system on the accent of a user leads to the variation in its performance, as the people from different backgrounds have different accents. Accent labeling and conversion have been reported as a prospective solution for the challenges faced in language learning and various other voice-based advents. In the English TTS system, the accent labeling of unregistered words is another very important link besides the phonetic conversion. Since the importance of the primary stress is much (...) greater than that of the secondary stress, and the primary stress is easier to call than the secondary stress, the labeling of the primary stress is separated from the secondary stress. In this work, the labeling of primary accents uses a labeling algorithm that combines morphological rules and machine learning; the labeling of secondary accents is done entirely through machine learning algorithms. After 10 rounds of cross-validation, the average tagging accuracy rate of primary stress was 94%, the average tagging accuracy rate of secondary stress was 94%, and the total tagging accuracy rate was 83.6%. This perceptual study separates the labeling of primary and secondary accents providing the promising outcomes. (shrink)

Frequency selective surface -based intelligent spatial filters are capturing the eyes of the researchers by offering a dynamic behavior when exposed to the electromagnetic radiations. In this manuscript, a concept of creating complementary structures which stems from Babinet’s principle is illustrated. A hybrid complementary pair of FSS comprising double square loop FSS and double square slot FSS on either side of the dielectric substrate is proposed. DSLFSS offers band-pass behavior and can be placed as a superstrate, whereas DSSFSS behaves as (...) a band-stop intelligent spatial filter that blocks the radiations falling on it, thus making them applicable for use as a substrate. The technique utilized for analyzing DSLFSS and DSSFSS structures is based on the equivalent circuit modeling and transmission line methodology. The CPFSS structure offers the design simplicity, hence, suitable for placing them with the printed patch antenna radiators in wireless networking devices operating in sub-6 GHz 5G spectrum. DSLFSS offers band-pass behavior ranging from 2.99 to 5.56 GHz, whereas DSSFSS offers band-stop behavior ranging from 2.85 to 5.42 GHz covering all n77, n78, and n79 bands of FR1 spectrum of sub-6 GHz 5G range. The passband and the stopband offered by the two structures of CPFSS geometry are stable to oblique angles of incidence and the proposed design also offers polarization-independent behavior. The thickness of the dielectric region existing within the pair of designed structures is critical for the location of the passbands and the stopbands. The impact of the overall thickness of the dielectric substrate on the passbands and stopbands is also reported in this article. (shrink)

Journal of Human Values, Volume 28, Issue 3, Page 181-199, September 2022. The study addresses the challenging crisis of sustainable consumption. It explores the philosophy of Samkhya, which is based on nature and spirit, also found in Vedantic knowledge, and synthesizes it with the knowledge of spiritual well-being found in modern literature to conceptualize the roles of the direct, mediating and moderated mediation relationships of different Vedantic personality types, spiritual well-being and family structure with consciousness for sustainable consumption and its (...) three dimensions of environment, society and economy. Based on the conceptualized roles, different models have been proposed. (shrink)

The study deals with some of the central issues concerning the notion of death as discussed in Theravāda (Pāli Buddhism) as well as Mahāyāna Buddhism. What is the sense that death is regarded as an instance of duḥkha (Sanskrit) or dukkha (Pāli)? The research claims that here, firstly, the word duḥkha/dukkha is used as an adjective (which means ‘unsatisfactory’) rather than a noun (which means 'pain' or 'suffering'). Secondly, by death, the Buddha did not mean the act of dying but (...) the experience of someone's death or the idea of death. The Buddha also talked about deathlessness as the goal. Here, deathlessness does not amount to accepting something eternal but developing a proper perspective towards death by meditations such as that on impurity ( аśubhabhāvanā ) and contemplation on death ( maraṇānussati ). If the cessation of the cycle of rebirths and re-deaths ( punarmṛtyu ) is the ultimate goal that the arhat (Sanskrit), or arahant (Pāli), achieves, then the same should apply to Tathāgata. In that case, the problem suggests itself: how could the question of Tathāgata’s existence after death be accounted for as an unanswerable ( avyākṛta )? The study opines that the reason behind this is the profound, immeasurable, unfathomable nature attributed to Tathāgata. The research also discusses the basic difference between the attitudes on death in Śrāvakayāna and Mahāyāna. Lastly, it deals with the question of whether termination of one’s own life is permissible in Buddhism under certain conditions. (shrink)

The justification and rationality of this paper is to present some fundamental principles, theories, and concepts that we believe moulds the nucleus of a good artificial intelligence (AI) society. The morally accepted significance and utilitarian concerns that stems from the inception and realisation of an AI’s structural foundation are displayed in this study. This paper scrutinises the structural foundation, fundamentals, and cardinal righteous remonstrations, as well as the gaps in mechanisms towards novel prospects and perils in determining resilient fundamentals, accountability, (...) and AI’s convoluted and responsible implications. We outline a number of salient and practical benefits, in which to place moral norms within the mise en scène of AI, to delineate the rudimentary ethical dilemmas and decorous directions within the realms of AI.

Following Lyotard's death in 1998, this book provides an exploration of the recurrent theme of education in his work. It brings to a wider audience the significance of a body of thought about education that is subtle, profound and still largely unexplored. This book also makes an important contribution to contemporary debates on postmodernism and education.

Eine geradezu mythologische Narration des Okzidents besagt, dass der Mensch mit der europäischen Aufklärung begonnen habe, sein Schicksal nicht mehr übergeordneten Instanzen zu überlassen, sondern es im mutigen Vertrauen auf die eigenen Potenzen in die eigene Hand zu nehmen. Mal abgesehen davon, dass dieser Topos vom selbstbestimmten Menschen die Mythologien und Heldenepen zahlreicher, auch nichteuropäischer Kulturen prägt, scheint an der neuzeitlichen europäischen Narration doch zumindest auffällig, ihr Ideal von Selbstwerdung wie auch gesellschaftlicher und individueller Vervollkommnung an die Vorstellung stetigen Fortschritts (...) zu binden. Am Beispiel einiger zentraler hinduistischer Vorstellungen werde ich aus einer kulturpsychologischen Perspektive zu skizzieren versuchen, dass individuelle Perfektionierung auch in kosmologischen Vorstellungen als möglich gedacht werden kann, in denen stetige Auflösung und Zerstörung als Prinzip alles Seins betont werden. Abschließend werden einige knappe Überlegungen dazu angestellt, wie derartige Vorstellungen dazu beitragen können, bestimmte Aspekte gegenwärtiger Gesellschaft und Politik umfassender zu analysieren.Sri Krishna:Ich bin der Tod, der Zerstörer von Welten.[...] Ich bin die Zeit, die Verschwenderin von Völkern. Ich mache den Augenblick reif für ihren Zerfall.Arjuna:Feuergesichtiger, du hauchst die Welten zu Asche. [...] Die furchtbaren Hauer all deiner Münder knirschen.

Taking psychology and its attempt to deal scientifically with the meaning of culture as an example, this article outlines the meaning of various historiographic narratives of disciplinary self-perception with regard to tensions between the natural and cultural sciences. The thesis postulates that these self-images are of psychological, especially cultural-psychological, importance. Only a psychology that includes aspects of the cultural sciences is able to deal with this vital aspect of the broader field.

The nature of contemporary issues facing our society and the research being conducted to deal with them clearly crosses the boundaries of traditional academic disciplines. Hence, it is suggested that school education should provide students with trans-disciplinary learning experiences in which students learn to use knowledge from various academic disciplines in an integrated format within the context of specific real-life issues. Trans-disciplinary approaches hold the promise of helping students see real-life issues in an organic rather than fragmented manner and be (...) able to apply knowledge to deal with them in an organic manner. A majority of the contemporary issues facing our society relate to the environment. Hence, environmental issues can serve as excellent organizers for designing trans-disciplinary instructional units. Arguments in favor of organizing trans-disciplinary instruction around contemporary environmental issues and an approach for doing so are presented in this article. (shrink)

The debates of the 1980s and 1990s on methodological individualism versus methodological holism have not been adequately resolved. Within analytical Marxism, G.A. Cohen, John Roemer, Jon Elster and others have come down in favour of methodological individualism as part of the effort to make analytical Marxism more 'scientific' and 'rigorous' than earlier versions of Marxism. In doing so they have presented methodological individualism as a necessary ingredient in ridding Marxism of obscurantism. This view is here challenged from a pragmatist philosophical (...) perspective. It is argued that, from such a perspective, the debates between the individualists and holists should have been dissolved rather than resolved in favour of the individualists. It is suggested that such dissolution would even strengthen analytical Marxism by redirecting analytical energies towards real social and political problems in the contemporary world and away from endless methodological debate.

The theory of granular partitions (TGP) is a new approach to the understanding of ontologies and other classificatory systems. The paper explores the use of this new theory in the treatment of task-based clinical guidelines as a means for better understanding the relations between different clinical tasks, both within the framework of a single guideline and between related guidelines. We used as our starting point a DAML+OIL-based ontology for the WHO guideline for hypertension management, comparing this with related guidelines and (...) attempting to show that TGP provides a flexible and highly expressive basis for the manipulation of ontologies of a sort which might be useful in providing more adequate Computer Interpretable Guideline Models (CIGMs) in the future.

Over the years, the urban heat vulnerability has evolved as a pressing global concern for researchers and policymakers alike. Numerous studies have aimed at mitigating the adverse effects of urban heat vulnerability on public health and safety. However, the critical task of selecting the most fitting indicator for urban heat islands in public spaces is not emphasized in the existing studies, considering the diverse indices available. Beyond identification, studies that delve into the prioritization of these indices and the determination of (...) optimal variables along with their respective weights are scanty. The present study attempts to address these gaps in urban heat vulnerability research through the lens of natural solutions. The study employs a fuzzy analytical hierarchy approach to ascertain the weights of selected criteria, providing a nuanced understanding of the multifaceted factors influencing their applicability. Real-time impact estimation using the fuzzy technique for order of preference by similarity to ideal solutions enhances the practicality of the findings. The results reveal a set of pivotal characteristics crucial for constructing a robust heat vulnerability index, facilitating the prioritization of selected criteria. The implementation of this hybrid methodology culminates in a streamlined, precise, and practical tool for evaluating heat vulnerability in hot urban public spaces. These findings contribute valuable insights to the academic discourse and offer a tangible resource for policymakers and practitioners. The proactive approach provides a roadmap for addressing impending challenges related to urban heat vulnerability, marking a positive step toward creating resilient and sustainable urban environments.

Representations of these algebras in terms of rough sets are obtained. Moreover, logics for these algebras are shown to be sound and complete with respect to rough set semantics. (shrink)

Philosophy in Indian tradition as a purely secular and rational exercise can be located in the Lokayata/Carvaka school of Indian philosophy. Due to the lack of substantial literary sources, scholars did not try to explore Lokayata philosophically. The present work is the first attempt to explore the philosophical energies inherent in the scattered Carvaka literature through critical and analytical discussions firmly grounded in textual evidences.

This article starts with a case outlining ethical challenges encountered in participatory action research (PAR) on vaccine hesitancy in rural India during Covid-19. Community researchers were recruited by a not-for-profit organisation, with the aim of both discovering the reasons for vaccine hesitancy and encouraging take-up. This raised issues about the roles and responsibilities of local researchers in their own communities, where they might be blamed for adverse reactions to vaccination. They and their mentor struggled with balancing societal protection against individual (...) rights to make choices. These themes are explored in two commentaries discussing the difficulties in balancing ethics in public health (prioritising societal benefits), social research (protecting participants from harm and respecting their rights not to be involved) and participatory research practices (maximising democratic participation and decision-making). As discussed in the first commentary, often these cohere, but tensions can arise. The second commentary also raises the issue of epistemic justice, questioning the extent to which the villagers could have a say in the design, implementation and interpretation of the research, and the dangers of not hearing the voices and arguments of people who reject vaccination. The case and commentaries highlight the complexities of PAR and additional challenges in a public health context. (shrink)

Type II DNA topoisomerase activity is required to change DNA topology. It is important in the relaxation of DNA supercoils generated by cellular processes, such as transcription and replication, and it is essential for the condensation of chromosomes and their segregation during mitosis. In mammals this activity is derived from at least two isoforms, termed DNA topoisomerase IIα and β. The α isoform is involved in chromosome condensation and segregation, whereas the role of the β isoform is not yet clear. (...) DNA topoisomerase IIβ was first reported in 1987. Here we review the research on DNA topoisomerase IIβ over the last 10 years. BioEssays 20:215–226, 1998.© 1998 John Wiley & Sons, Inc. (shrink)

Is it possible to look at schools as spaces for encounters? Could schools contribute to a deliberative mode of communication in a manner better suited to our own time and to areas where different cultures meet? Inspired primarily by classical (Dewey) and modern (Habermas) pragmatists, I turn to Seyla Benhabib, posing the question whether she supports the proposition that schools can be sites for deliberative communication. I argue that a school that engages in deliberative communication, with its stress on mutual (...) communication between different moral perspectives, gives universalism a procedurally oriented meaning, serving as an arena for encounters that represents a weak public sphere. An interactive universalism of this kind attaches importance to developing an ability and willingness to reason on the basis of the views of others and to change perspectives. In that respect, the institutional arrangements of schools are potential parts of the political dimension of cosmopolitanism, as well as its moral dimension, in terms of the obligations and responsibilities we develop through our institutions and in our actions as human beings towards one another.

This book offers a systematic and radical introduction to the Buddhist roots of Pātañjalayoga or the Yoga system of Patañjali. By examining each of 195 aphorisms of the Yogasūtra, along with discussions on the Yogabhāṣya, it shows that traditional and popular views on Pātañjalayoga obscure its true nature. The book argues that Patañjali's Yoga contains elements rooted in both orthodox as well as heterodox philosophical traditions, including Sāṅkhya, Jaina and Buddhist thought. With a fresh translation and a detailed commentary on (...) the Yogasūtra, the author unearths how several terms, concepts, and doctrines of Patañjali's Yoga can be traced to Buddhism, particularly the Abhidharma Buddhism of Vasubandhu and the early Yogācāra of Asaṅga. The work presents the Yogasūtra of Patañjali as a synthesis of two perspectives: the metaphysical perspective of Sāṅkhya and the empirical-psychological perspective of Buddhism. Based on a holistic understanding of Yoga, the study explores key themes of the text, such as meditative absorption, means, supernormal powers, isolation, Buddhist conceptions of meditation, the interplay between Sāṅkhya and Buddhist approaches to suffering and emancipation. It further highlights several new findings and clarifications on textual interpretation and discrepancies. An important intervention in Indian and Buddhist philosophy, this book opens a new way of looking at the Yoga of Patañjali in the light of Buddhism beyond standard approaches, and will greatly interest scholars and researchers of Buddhist studies, Yoga studies, Indian philosophy, philosophy in general, literature, religion and comparative studies, Indian and South Asian Studies, and the history of ideas.

Education lies at the heart of the Universal Declaration of Human Rights (UDHR): ‘Education shall be directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms’. However, when education is mentioned in the philosophical literature on human rights, or even within the literature on educational policy, it is usually within the context of its being treated as a specific right—as education as a human right rather than human rights education. (...) Taking rights and obligations to be intimately tied within a full human rights educational regime, I argue for the role of education in establishing and realizing freedom from poverty as a human right. The arguments for why this freedom should be considered a human right are compelling. I offer five educational moments in the human rights movement in general, and the arguments for freedom from poverty as a human right, more specifically, in my discussion of human rights education.

'Katihar to Kennedy' is an extraordinary journey of a man from dusty alleys of Katihar to the gleaming pathways of Kennedy. It is an autobiographical account of a small-town boy who starts his journey from a tiny town of Bihar, in one of India’s economically backward districts and is able to reach the Harvard Kennedy School in Cambridge, Massachusetts. The journey also depicts the inner conflicts of a man and his continuous efforts to overcome all the difficulties in his path (...) while fighting with his inner shortcomings. The book is about the lessons he learned – from failures as well as from moments of triumph. These are learned while engaging intimately with harsh socio-economic realities, and contrasts he experienced while moving between cities, institutions, and job roles. It is also a book of honest confrontation, of a person’s own ego and pride. (shrink)

What did science make possible for colonial rule? How was science in turn marked by the knowledge and practices of those under colonial rule? Here I approach these questions via the social history of Madras Observatory. Constructed in 1791 by the East India Company, the observatory was to provide local time to mariners and served as a clearinghouse for the company’s survey and revenue administration. The astronomical work of Madras’ Brahmin assistants relied upon their knowledge of jyotiśāstra [Sanskrit astronomy/astrology], and (...) can be seen as a specialized form of the kind of South Indian scribal labor and knowledge that also staffed the company’s tax offices. If at Greenwich the division of labor meant observatory work bore resemblances to the factory and the accounts office, in Madras, astronomy and accounting drew on similar labor forms because they were part of the same enterprise. But the company did not just adapt preexisting forms of labor, it also attempted to produce its own at a school built near the observatory to train “half-caste” orphans as apprentice surveyors and assistant computers. The school, staffed by the Brahmins, drew upon knowledge and pedagogical practice associated with the tinnai, the schools in which upper-caste children learned to read, write, and calculate. For a time, the observatory’s social order was literally “half-caste.” The paper also considers how the relationship between caste, status, and instrument was reflected in the visual and material culture of the observatory, such as in Indian-language inscriptions on its central pillar. For company astronomers, the measurement of time meant reworking the relationships among the Indian past, the colonial present, and an imperial posterity. Science under colonial rule spanned multiple temporal and social registers because it was the result of negotiations between the demands of political economy and the knowledge and practices of colonized others.

The Unified Medical Language System and the Gene Ontology are among the most widely used terminology resources in the biomedical domain. However, when we evaluate them in the light of simple principles for wellconstructed ontologies we find a number of characteristic inadequacies. Employing the theory of granular partitions, a new approach to the understanding of ontologies and of the relationships ontologies bear to instances in reality, we provide an application of this theory in relation to an example drawn from the (...) context of the pathophysiology of hypertension. This exercise is designed to demonstrate how, by taking ontological principles into account we can create more realistic biomedical ontologies which will also bring advantages in terms of efficiency and robustness of associated software applications.
