One of the important measures of quality of education is the performance of students in academic settings. Nowadays, abundant data is stored in educational institutions about students which can help to discover insight on how students are learning and to improve their performance ahead of time using data mining techniques. In this paper, we developed a student performance prediction model that predicts the performance of high school students for the next semester for five courses. We modeled our prediction system as (...) a multi-label classification task and used support vector machine (SVM), Random Forest (RF), K-nearest Neighbors (KNN), and Multi-layer perceptron (MLP) as base-classifiers to train our model. We further improved the performance of the prediction model using a state-of-the-art partitioning scheme to divide the label space into smaller spaces and used Label Powerset (LP) transformation method to transform each labelset into a multi-class classification task. The proposed model achieved better performance in terms of different evaluation metrics when compared to other multi-label learning tasks such as binary relevance and classifier chains. (shrink)

Configural face processing precedes featural face processing under the face-attended condition, but their temporal sequence in the absence of attention is unclear. The present study investigated this issue by recording visual mismatch negativity, which indicates the automatic processing of visual information under unattended conditions. Participants performed a central cross size change detection task, in which random sequences of faces were presented peripherally, in an oddball paradigm. In Experiment 1, configural and featural faces were presented infrequently among original faces. In Experiment (...) 2, configural faces were presented infrequently among featural faces, or vice versa. The occipital-temporal vMMN emerged in the 200–360 ms latency range for configural, but not featural, face information. More specifically, configural face information elicited a substantial vMMN component in the 200–360 ms range in Experiment 1. This result was replicated in the 320–360 ms range in Experiment 2, especially in the right hemisphere. These results suggest that configural, but not featural, face information is associated with automatic processing and provides new electrophysiological evidence for the different mechanisms underlying configural and featural face processing under unattended conditions.

ABSTRACT The publication of Ta-Nehisi Coates's Between the World and Me has been met with mixed and widespread reviews and reactions. Responses have ranged from a critique of his “pessimism” to a grand celebratory remark announcing him as the next great intellectual and social critic in the mold of James Baldwin. Yet there are few reviews that have acknowledged Coates's project as a materialist cosmology of the body, meaning that while Coates embraces terrestriality over transcendence, he nevertheless sees great possibilities (...) in the body, the greatest of which is the creation and destruction of “galaxies of reality.” More than just examining race and race relations in the midst of one of the highest incidences of black death, Coates's book examines the meaning of this lived reality at the level of the body and its capacities to both open up and close down material possibilities of life and death. This article will investigate the meaning of the body in Coates's book, its relationship to “race,” and will argue that while Coates does not offer us a solution to the problem of racial embodiment, he does offer the idea that one can and must make peace within the chaos of existence.

Social movements have driven large shifts in public attitudes and values, from anti-slavery to marriage equality. A central component of these movements is moral persuasion. We conduct a randomized-controlled trial of pro-vegan animal-welfare pamphlets at a college campus. We observe the effect on meat consumption using an individual-level panel data set of approximately 200,000 meals. Our baseline regression results, spanning two academic years, indicate that the pamphlet had no statistically significant long-term aggregate effects. However, as we disaggregate by gender and (...) time, we find small statistically significant effects within the semester of the intervention: a 2.4 percentage-point reduction in poultry and fish for men and a 1.6 percentage-point reduction in beef for women. The effects disappear after 2 months. We merge food purchase data with survey responses to examine mechanisms. Those participants who self-identified as vegetarian, reported thinking more about the treatment of animals or expressed a willingness to make big lifestyle changes reduced meat consumption during the semester of the intervention. Though we find significant effects on some subsamples in the short term, we can reject all but small treatment effects in the aggregate. (shrink)

This book is affords us the opportunity to rediscover Richard Wright and reexamine his work and its continuing significance in light of our contemporary situation. Moreover, the collection allows us to analyze Wright’s relationship and contribution to the discipline of philosophy, both challenging and enriching its traditional ideas and concepts.

Much of Africana philosophy concerns itself with the social and political; that is, those issues that relate to “racism” or “racialization” as suffered by Africana persons. Within this understanding, Africana persons become defined by and studied through theories which presume a shared anthropology with their white counterparts. This essay argues that Africana philosophy would benefit in thinking beyond “race” and “racialization” towards a theorization of the cultural aspects of Africana persons as the basis of our study and understanding of Africana (...) persons. Specifically, this essay theorizes the relationship between mytho-logos and the culturalogic as offering a new lens through which to analyze the range problems confronting Africana philosophy.

Three new books explore what Christian ethics looks like if it is to take seriously its theological basis for engaging the world.Stephen D. Long, professor of systematic theology at Marquette University, attends to the difficulties in predicating “Christian” of “ethics,” yet he is concerned more with explaining how Christianity can be ethical rather than vice versa. His Christian Ethics: A Very Short Introduction opens with a quote from Christopher Hitchens and later dedicates almost an entire chapter to analyzing the failures of Christian ethics. From the Crusades to colonialism, the Galileo affair to slavery, Long provocatively asks whether modern ethics emerges as a result of the failure of Christian moral claims. While not sidestepping the difficulties in Christian history, Long is careful to note how this history is often distorted to serve the goals of contemporary secular politics, goals which he points out have resulted in the bloody failures of the twentieth century. Perhaps a renewed interest in Christian ethics, Long notes, is a result of the failures of secularism.Long manages to cover a surprising breadth of material in his brief book, from a sweeping historical overview of Christian theology to a final chapter on [End Page 195] the practical matters of sex, money, and political power. Long also summarizes some important theological differences among Christians that lead to practical disagreements about the nature of Christian ethics. His overview of the Catholic-Lutheran convergence on matters of faith and works is particularly helpful in establishing the theological basis for an ecumenical Christian ethics. This historical survey serves to illustrate that ethics is both an integral part of and a contradiction to Christianity. Still, argues Long, while Christianity may claim to be more than ethical, it may never claim to be less.While commendable in breadth, the genre of the “very short introduction” precludes depth and must necessarily omit important information. In his summary of Catholic ethics, for example, Long addresses nominalism and probabilism but omits the Catholic social tradition, a particularly glaring omission given his topic. In the end, the target audience is the educated and curious layperson, more suitable for a church group than a classroom, though this is reflective of the nature of “the very short introduction” series and does not indicate any limitation in Long’s skill as a scholar.In the spirit of brevity, Michael Banner, Fellow of Trinity College in Cambridge, offers Christian Ethics: A Brief History, which, like any brief history, paints with broad and admittedly selective strokes. The aim of this work is not to evaluate the normative value of Christian claims but rather to establish the ethical implications of Christian belief. Unlike Long, who directly addresses the ethical failures of the church, Banner is more apologetic. In clarifying the difficulties of writing a text such as this one, he observes that Christian history has not been guided by texts as much as by action. In this vein, Banner begins not chronologically but with the Rule of St. Benedict and its call to live in a relationship with God and neighbor characterized by love.Banner grounds the theoretical dimension of Christian ethics in this emphasis on practice. Given the way of life Christians are called to, what are its limitations and possibilities? Banner turns to Augustine’s notion of the weakness of the will and the human creature’s need for grace, which he then places in creative tension with Aquinas’s emphasis on the harmony between faith and reason. In somewhat breathtaking conciseness, Banner describes how the Scholastic emphasis on natural law, casuistry, and the categorizing of sins led to what he calls... (shrink)

ABSTRACT In characterizing his second studio album, good kid, m.A.A.d city, as a “short film” Kendrick Lamar offers something of a public declaration: We, the listening audience, are not hearing another hip-hop album, just another “autobiography” or slice of one person's life, but, rather, something else; we are hearing a mixture of social, cultural, and personal narrative truth in what will be termed “autoethnography.” In doing so, Lamar offers us a new way of thinking about hip-hop as a whole, not (...) simply as a capitalistic enterprise or as a “black news” channel but as a distinct method for collecting data and understanding the experiences and existence of black people. While autoethnography is not a new method for research, it has been underutilized in philosophy as an approach to reading “texts” of all sorts, in particular Africana texts. This article analyzes Kendrick Lamar's second album to demonstrate why autoethnography is important as both a way of understanding reality and an expression of reality and also why it is centrally important for “doing” Africana philosophy.

So much of Africana philosophical research and scholarship has focused on personal, anecdotal experiences to tell/disclose larger intellectual narratives of race, nation, history, time, and space.1 Yet the personal nature in which Africana philosophy articulates itself has often been seen as particular and not yet universal—in other words, not rightly or properly “philosophical.” But understood methodologically, the sort of introspection inherent in Africana philosophy becomes not only one way of “doing” philosophy but the grounding for philosophical insight.2 Kendrick Lamar’s album (...) good kid, m.A.A.d. city provides for us an example of such methodological insight, proper for “doing” philosophy.3In characterizing...

Previous studies have found that P1 and P2 components were more sensitive to configural and featural face processing, respectively, when attentional resources were sufficient, suggesting that face processing follows a coarse-to-fine sequence. However, the role of working memory load in the time course of configural and featural face processing is poorly understood, especially whether it differs during encoding and retrieval stages. This study employed a delayed recognition task with varying WM load and face spatial frequency. Our behavioral and ERP results (...) showed that WM load modulated face SF processing. Specifically, for the encoding stage, P1 and P2 were more sensitive to broadband SF faces, while N170 was more sensitive to low SF and BSF faces. For the retrieval stage, P1 on the right hemisphere was more sensitive to BSF faces relative to HSF faces, N170 was more sensitive to LSF faces than HSF faces, especially under the load 1 condition, while P2 was more sensitive to high SF faces than HSF faces, especially under load 3 condition. These results indicate that faces are perceived less finely during the encoding stage, whereas face perception follows a coarse-to-fine sequence during the retrieval stage, which is influenced by WM load. The coarse and fine information were processed especially under the low and high load conditions, respectively. (shrink)

This book recasts Sartrean existentialism through Caribbean philosophies and the broader philosophies of the Global South. Each author's contribution embodies an aspect of creolizing thinking, understood as the articulation of cultural and conceptual hybridity under conditions of eurocentrism, epistemic colonialism, and the legacies of slavery.

This article addresses the challenge philosophical realism poses to the field of rhetoric by exploring the possibility of symbolic communion with nonhuman entities. As a matter of framing, I invoke Timothy Morton’s concept of the hyperobject to better understand the complexities of communicating with and about sublime nonhuman objects such as black holes. I then delineate how the stylistic modality of the weird best exploits the chasm between autonomous thingness and human presentation that is a primary source of consternation for (...) rhetorical realism. Finally, I draw from Kathe Koja’s novel The Cipher to reconsider a bizarre rhetoric of black holes which displays the omnipresent tension of accessible-alterity characteristic of the struggle to rhetorically breach the nonhuman world.

Name der Zeitschrift: Semiotica Jahrgang: 2014 Heft: 202 Seiten: 609-629.

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 29.3 (1999) 81-101 [Access article in PDF] Sex without Sex, Queering the Market, the Collapse of the Political, the Death of Difference, and AIDS: Hailing Judith Butler Brett Levinson It is interesting to note that in Judith Butler's study of the social construction of sex, Gender Trouble (as well as in the sequel, Bodies That Matter), one finds barely a trace of sex. Or to put matters more (...) bluntly: in Butler's study of gender critiques that avoid or dismiss the matters of hetero- and homosexuality, in her examination of the relationship of gayness and lesbianism to feminism, and in her exposition of a politics of queerness--as to fucking, not a word. This omission is not tangential to Gender Trouble. It determines Butler's entire undertaking. 1. The (In)difference of Performance By illustrating that sex, like gender, is a social construction, Butler strives to tear not sex but both sex and gender from biological essentialism. For as Butler insists, as soon as we imagine sex (woman/man) as naturally given, and gender (feminine/masculine) as a product of social forces, we fall into the very gender essentialism that we seemingly called into question. This is because the sex/gender binary makes sex the ground of gender: a woman may be masculine or feminine, and she may subvert the social norms that demand that women act in a certain manner. But throughout all of these gender reversals, she remains a woman. Her behavior, therefore, is either far from her sex (if she is subversive) or close to it (if she conforms). But in either case, it is measured in terms of that sex, which stands as the essence or foundation of the conduct. Hence, within such a discourse, gender stereotypes do not actually emerge as social (thereby deconstructible) constructs since the substructure (sex) of their edifice is given prior to production.This thesis, which ultimately reveals that the sex/gender split reproduces the woman/man binary--the foundation of sexism--opens the way for one of Butler's most renowned interventions: her theory of performativity. Butlerian performance traces the intersection of Derrida's concept of mimesis and Foucault's understanding of power. Derrida argues that if a mark (in writing) or a sound (in speech) is to form part of a language, it must be iterable. Language hinges on social conventions, and social conventions on repetition, ritual. Repetition, therefore, does not follow (from) a pregiven [End Page 81] [Begin Page 83] sign but is a condition of its possibility: a sign must be repeatable before it is a sign. 1Derrida often translates these ideas into an analysis of "the citation," a fact Butler fully exploits. An articulation, Derrida argues, must be a priori citable (again, iterable) if it is to function as an articulation, as a "speech act." This means that deviance, miscitation, recontextualization, and the possible transformation or loss of an enunciation--any or all of which could occur via a citation--belong essentially to that enunciation. The repetitions that yield rituals, habits, and then norms are the same iterations that undermine those norms. But this is true not only for speech. It holds as well for the law: the citing, execution, reading, writing, and acknowledgment of the law, hence the possibility of the law's shift and even disappearance, pertain to the law's groundwork.Gender Trouble posits patriarchy and compulsive heterosexuality as two such citable laws. And as laws, they are powerful but not inevitable. Indeed, because the law of normalcy harbors its own deviance as a condition of its public emergence or deployment, this normalcy opens the way for its own transgression. One is indeed subject to the law of the norm. But this subjection cannot not grant the very alternative agency/subjectivity it strives to suppress.Hence for Butler, queer types such as the "femme" or the "butch," as they perhaps flaunt (through dress, bodily image, or public demonstration) the constructed character of their own sexual identities, recite and dis-cover the constructed, artificial...

A quarterback like Green Bay's Aaron Rodgers gambles with a Hail Mary pass at the end of a football game when he has nothing to lose - the risky throw might turn defeat into victory, or end in a meaningless interception. Rodgers may not realize it, but he has much in common with figures such as George Washington, Rosa Parks, Woodrow Wilson, and Adolph Hitler, all of whom changed the modern world with their risk-loving decisions. In The Power of Nothing (...) to Lose, award-winning economist William Silber explores the phenomenon in politics, war, and business, where situations with a big upside and limited downside trigger gambling behavior like with a Hail Mary. Silber describes in colorful detail how the American Revolution turned on such a gamble. The famous scene of Washington crossing the Delaware on Christmas night to attack the enemy may not look like a Hail Mary, but it was. Washington said days before his risky decision, "If this fails I think the game will be pretty well up." Rosa Parks remained seated in the White section of an Alabama bus, defying local segregation laws, an act that sparked the modern civil rights movement in America. It was a life-threatening decision for her, but she said, "I was not frightened. I just made up my mind that as long as we accepted that kind of treatment it would continue, so I had nothing to lose.
