The purpose of crowd counting is to estimate the number of pedestrians in crowd images. Crowd counting or density estimation is an extremely challenging task in computer vision, due to large scale variations and dense scene. Current methods solve these issues by compounding multi-scale Convolutional Neural Network with different receptive fields. In this paper, a novel end-to-end architecture based on Multi-Scale Adversarial Convolutional Neural Network (MSA-CNN) is proposed to generate crowd density and estimate the amount of crowd. Firstly, a multi-scale (...) network is used to extract the globally relevant features in the crowd image, and then fractionally-strided convolutional layers are designed for up-sampling the output to recover the loss of crucial details caused by the earlier max pooling layers. An adversarial loss is directly employed to shrink the estimated value into the realistic subspace to reduce the blurring effect of density estimation. Joint training is performed in an end-to-end fashion using a combination of Adversarial loss and Euclidean loss. The two losses are integrated via a joint training scheme to improve density estimation performance.We conduct some extensive experiments on available datasets to show the significant improvements and supremacy of the proposed approach over the available state-of-the-art approaches.

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.

'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.

Online discussion forums are an essential and standard setup in online courses to facilitate interactions among learners. However, learners’ inadequate participation in online discussion forums is a long-standing challenge, which necessitates instructor intervention and the design consideration of online learning platforms. This research proposes and studies the role of mandatory participation, i.e., learners’ participation in online course forums by instructors’ requirements, in fostering their voluntary participation and boosting their learning performance. This novel effect link between mandatory participation and voluntary participation (...) has not been assessed in previous research. An empirical study is conducted using a large-scale dataset of 27,767 learners from a leading massive open online course platform in China. The findings indicate that besides its direct effect on learning performance, learners’ mandatory participation has a significant positive effect on their voluntary participation in online course forums, enhancing learning performance. Moreover, the effect of mandatory participation on voluntary participation varies across learner groups, being more prominent for early registrants than late registrants and part-time learners than full-time learners. This research contributes to the online learning literature by introducing mandatory participation as a viable approach to foster voluntary participation and boost learning performance through enhanced voluntary participation. It provides evidence on the effectiveness of the novel design feature of MOOC platforms that enables and facilitates the mandatory participation mechanism in online learning. (shrink)

The evaluation index system of ecological security of marine ranching is based on the assumption that there is independence among evaluation indexes in the existing studies, which ignores the complex interactive paths of marine ranching as an artificial ecosystem. In this study, the MRES evaluation network model that includes interdependent relationships is established based on the Driver-Pressure-State-Impact-Response model and the analytic network process method. Then, the probabilistic linguistic term sets and analytic network process methods are used to calculate the weights (...) of the evaluation indexes of MRES. The overall evaluation value and the contribution rate of clusters are consequently defined and analyzed to reflect the performance of MRES. Finally, a case study is carried out for evaluating the MRES of marine ranches in Rongcheng by means of the proposed method. The conclusions are summarized as follows: The weights of clusters are ranked as Responses > Impact > Driver > State > Pressure, and “scientific management of fishery resources” is the most important index; the MRES performance of marine ranches in the city of Rongcheng is at the medium security grade on the whole, and all 11 samples are driven by the response.

Due to the advent of deglobalization and regional integration, this article aims to adopt LASSO-based network connectedness to estimate the multiscale tail risk spillover effects of global stock markets. The results show that tail risk varies across frequencies and shocks. In static analysis, the risk is centered mostly on the developed European and North American markets at a low frequency, and regionalization is imposed on the moderate frequency. Moreover, emerging markets could be sources of risk spillover, especially at the highest (...) frequency where there is no absolute risk center. In dynamic analysis, we use rolling window estimation and find that different frequencies identify distinct episodes of shocks, which provides us with the reason for the diverse risk centers at different time scales in static analysis. Our findings provide heterogeneous financial practitioners, regulators, and investors with diverse characteristics of stock markets under multiple time horizons and help them operate their own trading strategies.

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.

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.

Some evolutionary psychologists claim that humans are good at creating superstimuli, and that many pleasure technologies are detrimental to our reproductive fitness. Most of the evolutionary psychological literature makes use of some version of Lorenz and Tinbergen’s largely embryonic conceptual framework to make sense of supernormal stimulation and bias exploitation in humans. However, the early ethological concept “superstimulus” was intimately connected to other erstwhile core ethological notions, such as the innate releasing mechanism, sign stimuli and the fixed action pattern, notions (...) that nowadays have, for the most part, been discarded by ethologists. The purpose of this paper is twofold. First, we will reconnect the discussion of superstimuli in humans with more recent theoretical ethological literature on stimulus selection and supernormal stimulation. This will allow for a reconceptualisation of evolutionary psychology’s formulation of (supernormal) stimulus selection in terms of domain-specificity and modularity. Second, we will argue that bias exploitation in a cultural species differs substantially from bias exploitation in non-cultural animals. We will explore several of those differences, and explicate why they put important constraints on the use of the superstimulus concept in the evolutionary social sciences. (shrink)

The technological virtual converges with our contemporary existence in a multitude of ways, which suggests a need to interrogate the question of the virtual existentially. Merleau-Ponty’s existential phenomenological account of embodiment is invaluable in this regard because the virtual is encountered from the basis of the facticity of the embodied individual – a facticity that is closely related to perception and motor intentionality. The current article argues that these characteristics of the body-subject should be taken into consideration in order to (...) develop a clearer description of the virtual. However, beyond an embodied account that relates to early technologies, Merleau-Ponty also presents through his concept of the flesh a novel avenue for the ontological investigation of the virtual. The flesh describes the intertwining of the body-subject and the world, which is suggestive of a new account of the individual’s sensibility in relation to the virtual. An original concept is suggested to describe the existential-ontological structure of the virtual: The embodied screen. The embodied screen as neologism presents an alternative conceptualisation of the coincidence of the body-subject (who understands the world spatially) with the virtual (as non-spatial). By tracing imaginative signification and embodied habitude in terms of the virtual, this article suggests certain existential implications of the virtual for contemporary being. (shrink)

In this essay I argue that a comprehensive understanding of addiction and its treatment should include an existential perspective. I provide a brief overview of an existential perspective of addiction and recovery, which will contextualize the remainder of the essay. I then present a case study of how the six-step philosophical practice method of Logic-Based Therapy can assist with issues that often arise in addiction treatment framed through an existential perspective.

The classic text on balance, inner calm, and the cultivation of tranquillity using the age-old techniques of Zen masters • Reveals the psychosomatic underpinnings of Zen, Taoism, and other Eastern traditions • Provides an alternative to the “chest out-belly in” postural attitude of the West • Includes translations of the wisdom teachings of three Japanese masters • Shows how the theory and practice of Hara helps us find our essential self When we speak of an individual’s state, we are actually (...) referring to something that transcends the duality of body and soul, something that reflects the entirety of a person’s being. Because each of us is a unity of body and soul, there is no psychic structure or inner tension that is not reflected outwardly in the form and order of the body. When we find the physical center of the body we also find the psychological center of the soul. According to Zen masters, by correcting posture and breathing to balance this center, one can cultivate inner tranquillity and balance: the state called Hara. In Hara, Karlfried Graf Dürckheim shows the Western world how to overcome the physical and spiritual decay of modern life by adopting the age-old techniques of Japanese Zen masters. By leaving behind the “chest out–belly in” posture and attitude of the West and adopting the belly-centered posture and attitude of Hara, individuals can live a calm, grounded, and more balanced life. Included in this classic text are vital life force practices and translations of the wisdom teachings of three Japanese Zen masters. This book also explores how the practice of Hara emphasizes empirical learning and the cultivation of self-knowledge through the perfection of arts such as painting and archery. (shrink)

Both "dialectical contradiction" and "logical contradiction" use the word "contradiction." This is misleading; it may easily lead people to believe that the word "contradiction" has only one meaning and thus confuse dialectical contradiction with logical contradiction. As a matter of fact, in dialectics and logic "contradiction" implies different things. "Contradiction" as used in dialectics refers to the two contradictory aspects in a thing. In contrast, "contradiction" as described in formal logic means the self-contradictoriness in thinking. For example, contradictions between the (...) productive forces and the relations of production, between one's merits and weaknesses, and between getting rid of the stale and taking in the fresh are all dialectical contradictions. "At once a man and a not-man," "at once existent and non-existent," "at once meritorious and non-meritorious," and so forth are all logical contradictions. The law of contradiction of formal logic excludes only the self-contradictoriness in thinking and has nothing to do with dialectical contradiction. The law of contradiction says that there can be no"A and not-A." That is to say, "A and not-A" is the logic contradiction that the law of contradiction should rule out. If we admit that dialectical contradiction is not logical contradiction, we then cannot describe dialectical contradiction as "A and not-A.". (shrink)

This book offers a critical feminist perspective on the widely debated topic of transitional justice and forgiveness. Louise Du Toit examines the phenomenon of rape with a feminist philosophical discourse concerning women’s or ‘feminine’ subjectivity and selfhood. She demonstrates how the hierarchical dichotomy of male active versus female passive sexuality – which obscures the true nature of rape – is embedded in the dominant western symbolic frame. Through a Hegelian and phenomenological reading of first-person accounts by rape victims, she excavates (...) an understanding of rape that also starts to open up a way out of the denial and destruction of female sexual subjectivity.

Central to philosophical practice is the application of philosophers' work by philosophical practitioners to inspire, educate, and guide their clients. For example, in Logic-Based Therapy (LBT) philosophical practitioners help their clients to find an uplifting philosophy that promotes guiding virtues that counteract unrealistic and often self-defeating conclusions derived from irrational premises. I will present the argument that Simone de Beauvoir’s existentialist ethics can be applied as an uplifting philosophy as per LBT methodology, and therefore has utility for philosophical practice. Additionally, (...) I will propose that Beauvoir’s existentialist ethics, as an uplifting philosophy, may act as an antidote for ideological obsession and ideology addiction. I will also suggest that LBT may be a suitable intervention when challenging the unrealistic conclusions derived from illogical premises in practical reasoning that contribute to ideological obsession, because it can contest irrational beliefs in a way that could mitigate the fragmentation anxiety that often arise when individuals relinquish maladaptive self-object organizations.

This research investigates the interplay between leadership styles and institutional corporate social responsibility (CSR) practices. A large-scale field survey of managers reveals that firms with greater transformational leadership are more likely to engage in institutional CSR practices, whereas transactional leadership is not associated with such practices. Furthermore, stakeholder-oriented marketing reinforces the positive link between transformational leadership and institutional CSR practices. Finally, transactional leadership enhances, whereas transformational leadership diminishes, the positive relationship between institutional CSR practices and organizational outcomes. This research highlights (...) the differential roles that transformational and transactional leadership styles play for a firm’s institutional CSR practices and has significant implications for theory and practice.

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)

The virtual has become the latest rostrum for ideological heteronormativity; it increasingly plays host to an insidious rhetoric of unjustifiably fixed and oppositional gender binaries that exhort heterosexuality as a norm. Conservative political and religious groups, as well as consumerist advertising, utilise digital technology to reinforce cast-in-stone and adversarial social perspectives for manipulative and exploitative ends. Contrastingly, the virtual may be mobilised to support and facilitate queering in contemporary societies and may positively counter such fixed ideological heteronormative categories of social (...) life. Crucial in this transformative account of the virtual is the body, which is for Merleau-Ponty the horizon of engagement with the world as a condition for perception and performativity. Queer perspectives may, in turn, overcome the oversight of Merleau-Ponty (as critically suggested by Judith Butler and Iris Marion Young) regarding the specific gendered characteristics of the body itself, and allows for an expanded embodied and queer conceptualisation of the virtual. A transformative vision of the virtual entails therefore a rethinking of our understanding of digital technology through (a) the phenomenology of the body-subject and (b) queer theory. I argue that the idea of the body as entirely discursive or performative (per queer theory) needs to be adjusted by explicating the foundational ontological characteristics of the body-subject’s encounter of the virtual.

Using a sample of 11,357 firm-year observations from the Chinese stock market for the period of 2001–2011, we investigate whether and how religion can mitigate earnings management. Specifically, based on geographic-proximity-based religion variables, we provide strong and robust evidence to show that religion is significantly negatively associated with the extent of earnings management, suggesting that religion can serve as a set of social norms to mitigate corporate unethical behavior such as earnings management. Our findings also reveal that the negative association (...) between religion and earnings management is less pronounced for firms with closer distance to the regulatory centers than for their counterparts, implying the substitutive effects between religion and the distance to regulators on mitigating earnings management. The above results are robust to different measures of earnings management, various religion variables, and a variety of sensitivity tests. (shrink)

Using a sample of Chinese to-be-listed firms during the period of 2006–2012, this study examines the influence of CEO-auditor dialect sharing (CADS) on pre-IPO audit quality and further investigates the moderating effects of auditor reputation and audit firm industry specialization. On the basis of information in personal identification cards, this study hand-collects data about CADS, and then provides strong and consistent evidence to show that CADS is significantly positively related with discretionary accruals (the inverse proxy for audit quality), suggesting that (...) CADS leads to the collusion between the CEO and the signing auditors, elicits pre-IPO earnings management, and eventually impairs pre-IPO audit quality. Moreover, both auditor reputation and audit firm industry specialization attenuate the positive effect of CADS on discretionary accruals. Furthermore, sensitivity tests suggest that above findings are robust to different measures of CADS and discretionary accruals, and above conclusions still stand after controlling for the endogeneity. Lastly, the findings using the post-IPO sample further validate the negative association between CADS and pre-IPO audit quality. (shrink)

When allocating scarce healthcare resources, the expected benefits of alternative allocations matter. But, there are different kinds of benefits. Some are direct benefits to the recipient of the resource such as the health improvements of receiving treatment. Others are indirect benefits to third parties such as the economic gains from having a healthier workforce. This article considers whether only the direct benefits of alternative healthcare resource allocations are relevant to allocation decisions, or whether indirect benefits are relevant too. First, we (...) distinguish different conceptions of direct and indirect benefits and argue that only a recipient conception could be morally relevant. We analyze four arguments for thinking that indirect benefits should not count and argue that none is successful in showing that the indirectness of a benefit is a good reason not to count it. We conclude that direct and indirect benefits should be evaluated in the same way. (shrink)
