In this article, a new adaptive data-driven strategy for voice activity detection using empirical mode decomposition is proposed. Speech data are decomposed using an a posteriori, adaptive, data-driven EMD in the time domain to yield a set of physically meaningful intrinsic mode functions. Each IMF preserves the nonlinear and nonstationary property of the speech utterance. Among a set of IMFs, the IMF that contains source information dominantly called characteristic IMF can be identified and extracted by designing a zero-frequency filter-assisted peaking (...) resonator. The detected CIMF is used to compute energy using short-term processing. Choosing proper threshold, voiced regions in speech utterances are detected using frame energy. The proposed framework has been studied on both clean speech utterance and noisy speech utterance. The proposed method is used for voice activity detection in the presence of white noise and shows encouraging result in the presence of white noise up to 0 dB. (shrink)

This article focuses on the Independent Communication Network as an instance of alternative media in Turkey. Throughout the study we define “alternative” media as non-dominant, counter-hegemonic media that prioritizes its distinct relationship with its audience. We report research based on in-depth interviews with the producers of the network’s online site “BIANET news” combined with focus group studies with communication students and women activists that are identified as the main audience segments of BIANET news by the newsmakers. By focusing on the (...) agents of both production and reception, this research enables us to examine participation and its form at both ends and to expound the problems of the conditions under which the user/audience can become the producer in Turkey.

The study ascertained (1) whether an observer's scope of justice with reference to either the moral agent or the target person of a moral act, would affect his/her judgements of the ethicality of the act, and (2) whether observer judgements of ethicality parallel the moral agent's decision processes in systematically evaluating the intensity of the moral issue. A scenario approach was used. Results affirmed both research questions. Discussions covered the implications of the findings for the underlying cognitive processes of moral (...) judgements, for the link between judgements of fairness and ethicality, as well as for the debate of ethical absolutism versus relativism.

The first comprehensive study of Nietzsche's earliest book, The Birth of Tragedy, this important volume by M. S. Silk and J. P. Stern examines the work in detail: its place in Nietzsche's philosophical career; its value as an account of ancient Greek culture; its place in the history of German ideas, and its value as a theory of tragedy and music. Presented in a fresh twenty-first-century series livery, and including a specially commissioned preface written by Lesley Chamberlain, illuminating its enduring (...) importance and relevance to philosophical enquiry, this accessible study has been revived for a new generation of readers.

‘It is supposed’, declared the poet Wordsworth in 1802, ‘that by the act of writing in verse an author makes a formal engagement that he will gratify certain known habits of association; that he not only thus apprizes the reader that certain classes of ideas and expressions will be found in his book, but that others will be carefully excluded. This exponent or symbol held forth by metrical language must in different eras of literature have excited very different expectations.’ For (...) his own era of literature Wordsworth proposed a language derived from the ‘simple and unelaborated expressions’ of the ‘language really spoken by men’, at the expense of ‘devices to elevate the style’ and ‘what is usually called poetic diction’.

. This paper illustrates the applications of various ensemble methods for enhanced classification accuracy. The case in point is the Pima Indian Diabetic Dataset. The computational model comprises of two stages. In the first stage, k-means clustering is employed to identify and eliminate wrongly classified instances. In the second stage, a fine tuning in the classification was effected. To do this, ensemble methods such as AdaBoost, bagging, dagging, stacking, decorate, rotation forest, random subspace, MultiBoost and grading were invoked along with (...) five chosen base classifiers, namely support vector machine, radial basis function network, decision tree J48, naïve Bayes and Bayesian network. The k-fold cross validation technique is adopted. Computational experiments with the proposed method showed an improvement of 16.14% to 22.49% in the classification accuracy compared to literature survey. Among the ensemble methods tried, MultiBoost ensemble with SVM classifier and grading ensemble with naïve Bayes showed the best performance followed by MultiBoost, stacking and grading ensemble with Bayesian classifier, rotation forest ensemble with RBF and grading and rotation forest ensemble with J48. This investigation conclusively proves the significance of cascading k-means clustering with ensemble methods in the enhanced accuracy in categorization of diabetic dataset. (shrink)

Abstract:The present paper focuses on the linkage between two academic paradigms in the enquiry into business ethics: normative philosophy and empirical social sciences. The paper first reviews existing research pertaining to a normative-empirical dialogue. Further empirical data on the relationship between various standards of morality are discussed in relation to the normative frameworks of ethics. Lastly, future directions for such a dialogue in business ethics are suggested.

The aim of the following note is to draw attention to certain links between the marriage of Claudius and Agrippina and that of Nero and Octavia. Previous writers have not, so far as I know, dealt fully with the implications of these marriages, especially when they are seen in the light of the Silanus affair of A.D. 48–49. In each case, it will be argued here, Claudius may have been impressed by Greek precedents.

s This paper reports studies designed to examine perceptions of preferential selection. Subjects evaluated the fairness of hypothetical cases of selection decisions based on either candidate sex or ethnic origin. A within-subjects design and a between-subjects design yielded convergent results showing that (1) preferential selection was perceived as unfair, irrespective of respondent sex or the basis for the preferential treatment (i.e., candidate sex or ethnic origin), (2) the level of perceived injustice was directly related to the discrepancy in merits between (...) the successful minority candidate and the more qualified yet unsuccessful majority candidate, and (3) the provision of either an ethical or legislative justification for the selection decisions further exacerbated feelings of injustice. Possible interpretations for the findings and practical implications of the study were then discussed. (shrink)

Among Plato's works, the Statesman is usually seen as transitional between the Republic and the Laws. This book argues that the dialogue deserves a special place of its own. Whereas Plato is usually thought of as defending unchanging knowledge, Dr Lane demonstrates how, by placing change at the heart of political affairs, Plato reconceives the link between knowledge and authority. The statesman is shown to master the timing of affairs of state, and to use this expertise in managing the conflict (...) of opposed civic factions. To this political argument corresponds a methodological approach which is seen to rely not only on the familiar method of 'division', but equally on the unfamiliar centrality of the use of 'example'. The demonstration that method and politics are interrelated transforms our understanding of the Statesman and its fellow dialogues. (shrink)

Motivation holds the key for harnessing the human potential in an organization. However, in modern management, motivation is used mainly as a strategy for enhancing the efficiency, productivity and performance of the employee. But for a more integral and effective realization of the human potential in an organization, motivation has to be used as a lever for human evolution and development, with enhanced performance as a spontaneous result. This article provides a comprehensive framework for evolving a motivational strategy, which will (...) lead to the progressive evolution of human potential in an organization. The article tries to integrate modern theories of motivation with ancient Indian perspectives, based on an integral psychology. (shrink)

One of the main events of our modern age is the emergence of the professional class or the knowledge-worker as a powerful and influential section of the society. The technocrat, manager, banker, entre-preneur and the finance-pro are some of the dominant types of these professional elite of our age. This brings us to the question, what are the values which can lead to quality and excellence in professional work? Professional excellence is normally associated with knowledge and skill. A professional is (...) a knowledge-worker and therefore knowledge and skill are undoubtedly some of the important values of professional work. But for excellence, knowledge and skill alone are not enough. Something more is needed. This article examines the guiding values of professional work in the modern corporate context. (shrink)

Although it is common in liberal and progressive circles to scoff at the idea that the Unites States is “exceptional”—a derision driven by an admirable suspicion of the chauvinistic connotations of the exceptionalist view—doing so obscures a significant reality. The United States is different, or at least rather unusual, in its social, cultural, and geo-strategic circumstances, especially when compared to the nations of Europe from which it draws the core of its intellectual traditions. What's more, the critique of American exceptionalism (...) has acquired its own troublesome politics. “It is extremely dangerous to encourage people to see themselves as exceptional, whatever….

Consider orthodox motivational judgment internalism: necessarily, A’s sincere moral judgment that he or she ought to φ motivates A to φ. Such principles fail because they cannot accommodate the amoralist, or one who renders moral judgments without any corresponding motivation. The orthodox alternative, externalism, posits only contingent relations between moral judgment and motivation. In response I first revive conceptual internalism by offering some modifications on the amoralist case to show that certain community-wide motivational failures are not conceptually possible. Second, I (...) introduce a theory of moral motivation that supplements the intuitive responses to different amoralist cases. According to moral judgment purposivism (MJP), in rough approximation, a purpose of moral judgments is to motivate corresponding behaviors such that a mental state without this purpose is not a moral judgment. MJP is consistent with conceptual desiderata, provides an illuminating analysis of amoralist cases, and offers a step forward in the internalist-externalist debates. (shrink)

Towards the general goal of generating a normative-empirical dialogue about ethics and justice, the present study explored three issues: (1) the extent to which the normative criteria of ethics and justice prescribed by moral philosophers are indeed reflected in managerial professionals' subjective beliefs of what ethical and just work behaviour ought to be, (2) the relationship between people's ought beliefs and their perceptions of actual ethical and just work behaviour, and (3) the relationship between the notions of ethics and justice. (...) To do so, a review of the normative and positive theories of ethics was carried out which revealed the key normative criteria of ethics (i.e., utility, rights, justice, principle and care) and justice (i.e., due procedure and due outcome). Using both the interview and the repertory grid procedures, key determinants of ethical and just work behaviour as perceived by the managerial professionals were generated. These determinants were used to construct the questionnaires for the assessment of people's subjective ought beliefs, and their is judgements, of ethical and just work behaviour. There were three respondent samples: managerial professionals, general public and university students. Results showed that (1) people's subjective ought beliefs closely reflected the normative standards of ethics and justice, (2) there were significant discrepancies between people's subjective ought beliefs and their perceptions of actual ethical and just work behaviour, (3) individual differences in ought beliefs had some influence on is judgements, (4) both the ought beliefs and is judgements pertaining to the notion of justice could be accounted for by measures of the other four criteria of ethics and in particular, the notion of rights. The implications of the findings for normative theories of ethics and for ethics education are discussed. (shrink)
