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 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)

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)

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)

Objective Moral distress is a complex phenomenon experienced by healthcare professionals. This study examined the relationships between key dimensions of Organizational Culture in Healthcare (OCHC)—perceived psychological safety, ethical climate, patient safety—and healthcare professionals’ perception of moral distress.Design Cross-sectional surveySetting Pediatric and adult critical care medicine, and adult hospital medicine healthcare professionals in the United States.Participants Physicians (n = 260), nurses (n = 256), and advanced practice providers (n = 110) participated in the study.Main outcome measures Three dimensions of OCHC were (...) measured using validated questionnaires: Olson’s Hospital Ethical Climate Survey, Agency for Healthcare Research and Quality’s Patient Safety Culture Survey, and Edmondson’s Team Psychological Safety Survey. The perception of moral distress was measured using the Moral Distress Amidst a Pandemic Survey. The hypothesized relationships between various dimensions were tested with structural equation modeling (SEM).Results Adequate model fit was achieved in the SEM: a root-mean-square error of approximation =0.072 (90% CI 0.069 to 0.075), standardized root mean square residual = 0.056, and comparative fit index =0.926. Perceived psychological safety (β= −0.357, p <.001) and patient safety culture (β = −0.428, p<.001) were negatively related to moral distress experience. There was no significant association between ethical climate and moral distress (β = 0.106, p = 0.319). Ethical Climate, however, was highly correlated with Patient Safety Culture (factor correlation= 0.82).Conclusions We used structural equation model to test a theoretical model of multi-dimensional organizational culture and healthcare climate (OCHC) and moral distress.Significant associations were found, supporting mitigating strategies to optimize psychological safety and patient safety culture to address moral distress among healthcare professionals. Future initiatives and studies should account for key dimensions of OCHC with multi-pronged targets to preserve the moral well-being of individuals, teams, and organizations. (shrink)

While living a life based on universal principles is well accepted by many, the reality of living acts as a great detriment to those who want to centre their lives on these timeless truths. Further, institutional mechanisms and work environments do not conform in general to such principle-centred living. The agents of the state, especially those in the police, have to work under tremendous obstacles and pressures from within and without, and often get a bad reputation, sometimes undeservingly. Moreover their (...) value systems may also degrade in these environments, a direction that requires to be altered by the ‘guardians of the law’. It is important to bring about alignment of values and ethical perceptions of state administrators with some universal laws. The Buddhist practice of vipassana mediation can play a significant role in such transformations, as is evident from the responses from Delhi Police personnel who underwent vipassana in one of their training programmes. Vipassana has made significant differences in the lives and perceptions of these trainees—both at the professional and personal level. This paper introduces these concepts and cites evidences from the feedback sheets of trainees to recommend worldwide adoption of such practices for those who occupy seats of power and responsibility. The feedback shows positive and very encouraging trends in all dimensions—work related, humanitarian, family and self—in other words, in professional, personal and deep inner lives. (shrink)

Critique of Justice is a collection of reflective essays on ditferent dimensions of justice written by eminent scholars of Philosophy and allied disciplines who are astively engaged in the academic pursuit and promoting the cause of philosophy The book is conceived from the standpoint of multi-perspectival approach to the multifarious concept of justice which is regarded as the highest value in any civilized society On the one hand from traditional metaphysical point of view justice consists of the eternal and immutable (...) principles hat are transcendent, objective and absolute, where as from modern positivistic and empirical approachjustice is ahuman construct relative to time and space. Justice is, therefore, regarded as complex and dynamic concept which is multi-dimensional. It synthesizes other values like rights, liberty equality and property. In this well researched book there are 40 scholarly articles covering a wide range from Plato's concept of justice to Nozick's concept of justice in the Western Philosophy and from Vedic concept of justice to Amartya Sen's view ofjustice in Indian perspective.

This book is 1st ever Hindi translation of Kant's German work “Zum ewigen Frieden: Ein philosophischer Entwurf”, translated into English by M. Cambell Smith, Lewis White Beck etc. with the title “Perpetual Peace: A Philosophical Sketch”. It is a small but significant political treatise that attempts to analyse the causes of war and fundamental conditions of peace. Apart from that political philosophy and different theories associated with international relations and perpetual peace as a moral and political ideal have been brought (...) under philosophical discussion whose relevance in the present political scenario is self-evident. For Kant, Perpetual Peace is an ideal as well as a concrete thought and his firm conviction that such an ideal can be realised, moral rejuvenation is the pre-condition of attaining perpetual peace. The need is to have transparent and faithful relations among different countries, correct interpretation of treaties and goodwill to be ensured at the level of implementation. The another condition for moral rejuvenation is to have a republican form of the constitution. Here we find linguistic beauty, clarity, systematic presentation and deep-rooted philosophical insights. This is undoubtedly valuable work for teachers and scholars and can be of great interest to the general reader too. (shrink)
