Housed in one volume for the first time are several of the seminal essays on Du Bois's contributions to sociology and critical social theory: from DuBois as inventor of the sociology of race to Du Bois as the first sociologist of American religion; from Du Bois as a pioneer of urban and rural sociology to Du Bois as innovator of the sociology of gender and culture; and finally from Du Bois as groundbreaking sociologist of education and cultural criminologist to Du (...) Bois as critic of the disciplinary decadence of the discipline of sociology. Unlike any other anthology or critical reader on Du Bois, this new volume offers an excellent overview of the critical commentary on arguably one of the most imaginative and innovative, perceptive and prolific founders of the discipline of sociology.

A dialogue between a foreign philosopher and a powerful statesman outline Plato's reflections on the family, the status of women, property rights, and criminal law.

We describe in some detail how to build an infinite computing machine within a continuous Newtonian universe. The relevance of our construction to the Church-Turing thesis and the Platonist-Intuitionist debate about the nature of mathematics is also discussed.

'The problem of the twentieth-century is the problem of the color-line.' Originally published in 1903, The Souls of Black Folk is a classic study of race, culture, and education at the turn of the twentieth century. With its singular combination of essays, memoir, and fiction, this book vaulted W. E. B. Du Bois to the forefront of American political commentary and civil rights activism. The Souls of Black Folk is an impassioned, at times searing account of the situation of African (...) Americans in the United States. Du Bois makes a forceful case for the access of African Americans to higher education, memorably extols the achievements of black culture (above all the spirituals or 'sorrow songs'), and advances the provocative and influential argument that due to the inequalities and pressures of the 'race problem', African American identity is characterized by 'double consciousness'. This edition includes a valuable appendix of other writing by Du Bois, which sheds light on his attitudes and intentions. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe. Each affordable volume reflects Oxford's commitment to scholarship, providing the most accurate text plus a wealth of other valuable features, including expert introductions by leading authorities, helpful notes to clarify the text, up-to-date bibliographies for further study, and much more.

A moving cultural biography of abolitionist martyr John Brown, by one of the most important African-American intellectuals of the twentieth century. In the history of slavery and its legacy, John Brown looms large as a hero whose deeds partly precipitated the Civil War. As Frederick Douglass wrote: "When John Brown stretched forth his arm... the clash of arms was at hand." DuBois's biography brings Brown stirringly to life and is a neglected classic.

This study used a partial least squares structural equation modelling (PLS-SEM) to estimate curriculum management's direct and indirect effects on university graduate programmes' viability. The study also examined the role of institutional effectiveness in mediating the nexus between the predictor and response variables. This is a correlational study with a factorial research design. The study's participants comprised 149 higher education administrators (23 Faculty Deans and 126 HODs) from two public universities in Nigeria. A structured questionnaire designed by the researchers was (...) used for data collection. The questionnaire was duly validated with an acceptable scale and item content validity indices. The dimensionality of the instrument was determined using exploratory factor analysis (EFA). Convergent validity was based on Average Variance Extracted (AVE), whereas discriminant validity was based on Fornell-Lacker criteria and the Hetero-Trait Mono-Trait (HTMT) ratio. Acceptable composite reliability estimates of internal consistency were reached for the three sub-scales. Following ethical practices, the questionnaire was physically administered to respondents and retrieved afterwards. Smart PLS (version 3.2.9) and SPSS (version 26.0) programs were used for all the statistical analyses. This study uncovered significant direct and indirect effects of curriculum management on the viability of graduate programmes. Institutional effectiveness significantly impacted graduate programmes’ viability while mediating the nexus between curriculum management and graduate programmes’ viability. Curriculum management and institutional effectiveness jointly explained a significant proportion of graduate programmes’ viability variance. The result of this study proved that graduate programmes’ viability depends, to a great extent, on how much curriculum is managed and how effective institutions are with their services. The result of this study can enable institutions seeking to run viable graduate programmes to re-evaluate their curriculum management practices and the effectiveness of their services. (shrink)

The regular increase in the proportion of resolved feet in the iambic trimeters of Euripides' later plays was first commented upon in 1807 by J. Gottfried Hermann, who therefrom deduced the principle that the date of any play of Euripides could be directly determined from the frequency of its resolutions. This criterion he restated in several of his works in the following years, and when Elmsley objected that it was of uncertain value on account of the small number of plays (...) of certain date by which it might be verified, he replied with a strong defence of his case: he did not, however, develop his principle in detail or give figures in its support. The first scholar to publish the totals of trisyllabic feet in each play was Zirndorfer: relying largely on these, he produced a chronology of Euripides' dramatic composition in several respects superior to any predecessor's. His conclusions were questioned by C. F. W. Müller, who, while accepting Hermann's thesis as being in general correct, doubted its reliability for determining the exact period of a tragedy's composition. Consequently, although he gave the totals of trisyllabic feet en passant, Müller made no attempt to suggest dates. At almost the same time as Müller's treatise appeared, J. Rumpel published an article giving a full and detailed list of references to all trisyllabic feet in Euripides: from this evidence he divided the dramas into four age-groups, but did not go so far as to assign specific dates.

Nearly every edition of Aeschylus published between 1782 and 1852 contained readings from what were called ‘Askew's collations’ or the ‘Askew MSS.’—usually referred to as Ask. A, Ask. B, Ask. C, Ask. D, Ask. a, Colb. 1, and Colb. 2. These MSS., which were very briefly described, were stated in these editions to be Paris MSS. which had been collated by Askew. Blomfield, however, discovered that Askew had transcribed all the collations from a note-book that had belonged to Needham, and (...) Pierron accused Askew of deliberate plagiarism and unscrupulous dishonesty. The late Prof. H. W. Smyth in a recent note on the subject attempted to identify the ‘Askew MSS.’, and maintained the charge of plagiarism; but his conclusions were based on inadequate evidence, and were consequently partly incorrect. A full study of all the available evidence, a summary of which I give below, not only clears Askew's name of any plagiarism, but also establishes the identity of the MSS. (shrink)

Providing efficient and clean power is a challenge for devices that range from the micro to macro in scale. Although there has been significant progress in the development of micro-, meso-, and macro-scale power supplies and technologies, realization of many devices is limited by the inability of power supplies to scale with the diminishing sizes of CMOS-based technology. Here, the authors provide an overview of piezoelectric energy harvesting technology along with a discussion of proof of concept devices, relevant governing equations, (...) and figures of merit. They present two case studies: (a) energy capture from the operation of a novel shear and elastic modulus indentation device subjected to applied voltage and (b) energy capture from vibrating commercial bimorph piezoelectric structures mounted on household appliances. Lastly, areas of development needed for realization of commercial energy harvesting devices are suggested. (shrink)

We discuss the philosophical status of the statement that (9n – 1) is divisible by 8 for various sizes of the number n. We argue that even this simple problem reveals deep tensions between truth and verification. Using Gillies's empiricist classification of theories into levels, we propose that statements in arithmetic should be classified into three different levels depending on the sizes of the numbers involved. We conclude by discussing the relationship between the real number system and the physical continuum.

I examine Popper’s claims about Newton’s use of induction in Principia with the actual contents of Principia and draw two conclusions. Firstly, in common with most other philosophers of his generation, it appears that Popper had very little acquaintance with the contents and methodological complexities of Principia beyond what was in the famous General Scholium. Secondly Popper’s ideas about induction were less sophisticated than those of Newton, who recognised that it did not provide logical proofs of the results obtained using (...) it, because of the possibilities of later, contrary evidence. I also trace the historical background to commonplace misconceptions about Newton’s method.Author Keywords: Newton; Popper; Induction; Principia; Kepler’s laws. (shrink)

The ideas and methods of cybernetics are increasingly penetrating the biological and medical sciences, and today we are justified in speaking of a new branch of science: biological and medical cybernetics. This branch already has a number of important and encouraging subfields.

The distribution of the parts among the actors in the O.C. is a problem that has long defied solution. In all the other extant plays of Aeschylus, Sophocles, and Euripides the dramatis personae can without difficulty be divided between three actors: but the construction of the O.C. is so complex that it does not admit any such simple allocation. When the part of Oedipus has been assigned to the first actor, and that of Antigone to the second, the roles of (...) the Stranger , Ismene , Creon , and Polyneices must clearly belong to the third: who, then, is to play Theseus ? It seems impossible to allot the part complete to any one of the three actors. Faced by this crux, all those who have dealt with the subject have chosen one or the other of two clear-cut alternatives, either the assumption of a fourth regular actor, or else the splitting-up of the single part of Theseus between two or three actors. These two alternatives, both of which are far from satisfactory—the former infringing the three-actor rule, the latter offending against scenic probability and realism—are fully examined below; at the end of the paper a new part-distribution is suggested, which, it is hoped, avoids both these faults.
