Path selection is one of the key technologies of wireless sensor network. A reasonable choice of coverage path can improve the service quality of WSN and extend the life cycle of WSN. Biogeography-based optimization is widely used in the field of cluster intelligent optimization because its search method has a better incentive mechanism for population evolution. In this paper, the move-in and move-out operation and mutation operation of the BBO algorithm enable WSN to find an efficient routing path. In this (...) paper, simulation experiments are carried out in two scenarios of regular deployment and random deployment of WSN nodes. The experimental results show that the quality of the WSN coverage path solution optimized by the BBO algorithm in the two scenarios is better than that of the particle swarm algorithm and genetic algorithm.

It is well documented that self-control has a positive effect on individuals’ subjective well-being. However, little research has focused on the moderators underlying this relationship. The present research used two studies to examine the moderating role of both trait and state motivation on the relationship between self-control and subjective well-being using psychometric and experimental models, respectively. In Study 1, we explored whether trait motivation moderated the relationship between trait self-control and subjective well-being using a psychometric model. In Study 2, we (...) examined the moderating effects of both trait and state motivation on the effect of state self-control on subjective well-being using an experimental model. Our results indicated that self-control had a positive effect on subjective well-being, with this relationship being primarily moderated by prevention motivation. When state and trait prevention motivations were congruent, self-control had the most obvious impact on subjective well-being. This study suggests that current understandings around the association between self-control and happiness is limited, implying that motivation should be the focus of future research. (shrink)

'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.

The distinguished American civil rights leader, W. E. B. Du Bois first published these fiery essays, sketches, and poems individually nearly 80 years ago in the Atlantic, the Journal of Race Development, and other periodicals. This volume has long inspired readers with its militant cry for social, political, and economic reforms for black Americans.

This chapter presents an essay by W. E. B. Du Bois that deals with the issue of race. He raises questions such as: What is the real meaning of race. What has, in the past, been the law of race development? What lessons has the past history of race development to teach the rising Negro people? He describes the American Negro Academy, which aims at once to be the epitome and expression of the intellect of the black-blooded people of America, (...) the exponent of the race ideals of one of the world's great races. He concludes by outlining a proposed creed for the Academy. (shrink)

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.

W. E. B. Du Bois was a public intellectual, sociologist, and activist on behalf of the African American community. He profoundly shaped black political culture in the United States through his founding role in the NAACP, as well as internationally through the Pan-African movement. Du Bois's sociological and historical research on African-American communities and culture broke ground in many areas, including the history of the post-Civil War Reconstruction period. Du Bois was also a prolific author of novels, autobiographical accounts, innumerable (...) editorials and journalistic pieces, and several works of history. Collected in one volume for the first time, The World and Africa and Color and Democracy are two of W E. B. Du Bois's most powerful essays on race. He explores how to tell the story of those left out of recorded history, the evils of colonialism worldwide, and Africa's and African's contributions to, and neglect from, world history. More than six decades after W. E. B. Du Bois wrote The World and Africa and Color and Democracy, they remain worthy guides for the twenty-first century. With a series introduction by editor Henry Louis Gates, Jr., and two introductions by top African scholars, this edition is essential for anyone interested in world history. (shrink)

New foreword written by HeritageMom, Amber O'Neal Johnston. "During a time when the United States needed to be reminded of the contributions Black people have made to its democracy, freedom, music, literature, and more, W.E.B. Du Bois took on the task of enumerating the gifts that we've provided to our country. "When I began reading The Gift of Black Folk...the story that unfolded was one that I had never anticipated. We the People of the United States, all of us, have (...) left our indelible mark on America the Beautiful." -Amber O'Neal Johnston In 1924, William Edward Burghardt (W.E.B.) Du Bois (1868-1963) penned The Gift of Black Folk in response to systemic racism in the United States, showing that "...the American spirit is a new and interesting result of diverse threads of thought and feeling coming not only from America but from Europe and Asia and indeed from Africa." Du Bois was the first African American to earn a Ph.D. from Harvard University, and later became a professor of history, sociology, and economics at Atlanta University. In 1909 he co-founded the NAACP. Du Bois was a lifelong leader and proponent of civil rights. Amber O'Neal Johnston is a writer, speaker, and home educator who blends life-giving books with a culturally-rich environment for her four children and others. She's the author of A Place to Belong, a guide for families of all backgrounds to celebrate cultural heritage and embrace inclusivity in the home and beyond, and she's known for sharing literary "mirrors and windows" on HeritageMom.com.

A thorough account of Africa's history and its lasting influence on Western culture told from the perspective of the disparate descendants who inherited its legacy. W.E.B. Du Bois highlights the hidden stories that connect these varied communities. Originally published in 1915, The Negro presents an expansive analysis of the African diaspora over the course of history. W.E.B. Du Bois uses a critical eye to survey the early depictions of the continent, debunking stereotypical myths about its social structure. He addresses the (...) generational impact of slavery as well as the capitalistic system that made it possible. It's an honest look at the effects of white supremacy, classism and its place in modern society. From Ethiopia and Egypt to the West Indies and Latin America, Africa's influence is undeniable. The Negro sheds light on the ignored history of the continent and its many descendants. It's a vital piece of literature that acknowledges and celebrates its cultural power. With an eye-catching new cover, and professionally typeset manuscript, this edition of The Negro is both modern and readable. (shrink)

This article explores the potential utility of the theory of Holism as developed by South African philosopher, British Commonwealth statesman and military leader, Jan Smuts, for philosophical counselling or practice. Central to the philosophical counseling process is philosophical counsellors or practitioners applying the work of philosophers to inspire, educate and guide their counselees in dealing with life problems. For example, Logic-Based Therapy, a method of philosophical counselling developed by Elliot Cohen, provides a rational framework for confronting problems of living, where (...) the counselor helps the counselee find an uplifting philosophy that promotes a guiding virtue that acts as an antidote to unrealistic and often self-defeating conclusions derived from irrational premises. We present the argument that Holism is one such uplifting philosophy which can be of utility to philosophical counselors or practitioners to help their counselees with confronting problems of living. Furthermore, we argue that Smuts’ articulation of freedom can act as a guiding virtue within this uplifting philosophy of Holism in accordance with the methodology of LBT. Smuts’ contribution to philosophy and psychology is arguably inadequately credited, and for this reason, and to the best of our knowledge, Smuts’ theory of Holism has yet to be discussed in the context of philosophical counseling or practice. Given these omissions, we begin this article with a discussion of his influence on 20th Century Anglo-American psychology. We then provide a brief historical context, and an introduction to the central argument of Smuts’ Holism, as well as a brief overview of the origins of Smut’s Holism and an introduction to his book Holism and Evolution. In the remainder of the article, we discuss several foundational concepts that underlie Smuts’ theory of Holism, as articulated and developed in his book Holism and Evolution, to substantiate our arguments. We conclude by highlighting the limitations of our article, limitations to Smuts’ model, and the challenges inherent in the use of a now largely antiquated theory, even by Smuts’ own admission nineteen years after its publication, for the purposes of contextualizing and substantiating the arguments and recommendations presented herein.
