This paper aims to address the difficulties of high school students in bridging their computational understanding with their visualization skills in understanding the notion of the limits in their calculus class. This research used a pre-experimental one-group pretest-posttest design research on 62 grade 10 students enrolled in the Science, Technology, and Engineering Program (STEP) in one of the public high schools in Zamboanga del Sur, Philippines. A series of remedial sessions were given to help them understand the function values, one-sided (...) limits, limits of a function, and its discontinuities with the aid of the GeoGebra. Results revealed that there is a significant improvement in their mathematics performance before and after the remediation, t(61) = -19.99, p<.05. The real-time feedback provided by the drawing interface of GeoGebra has provided the students the insights into how objects behave in geometrical space, bridging their understanding in locating the values shown by the computational algebraic processes. Additionally, the significant difference in the achievement reveals a large effect size (Cohen’s =2.54) which could be accounted for by the remediation using interactive activities in the GeoGebra.

Using a cross-modal semantic priming paradigm, both experiments of the present study investigated the link between the mental representations of iconic gestures and words. Two groups of the participants performed a primed lexical decision task where they had to discriminate between visually presented words and nonwords (e.g., flirp). Word targets (e.g., bird) were preceded by video clips depicting either semantically related (e.g., pair of hands flapping) or semantically unrelated (e.g., drawing a square with both hands) gestures. The duration of gestures (...) was on average 3,500 ms in Experiment 1 but only 1,000 ms in Experiment 2. Significant priming effects were observed in both experiments, with faster response latencies for related gesture–word pairs than unrelated pairs. These results are consistent with the idea of interactions between the gestural and lexical representational systems, such that mere exposure to iconic gestures facilitates the recognition of semantically related words.

Although women have long been participants in martial arts and other contact sports, the introduction of a women’s division in the Ultimate Fighting Challenge in 2012 brought women in combat sports into the media spotlight in an arguably unprecedented way. Yet, the increasing acceptance of women’s participation in combat sports does not necessarily mean that these sports are equally accessible to people of all genders. This article, extending insights from Iris Marion Young’s “Throwing Like a Girl,” will argue that the (...) modalities of feminine bodily existence pose barriers to women’s success in combat sports. Young discusses ways in... (shrink)

Criticism can sometimes provoke defensive reactions, particularly when it implicates identities people hold dear. For instance, feminists told they are upholding rape culture might become angry or upset, since the criticism conflicts with an identity that is important to them. These kinds of defensive reactions are a primary focus of this paper. What is it to be defensive in this way, and why do some kinds of criticism, or implied criticism, tend to provoke this kind of response? What are the (...) connections between defensiveness, identity, and active ignorance? What are the social, political, and epistemic consequences of the tendency to defensiveness? Are there ways to improve the situation? (shrink)

Critical remarks on Geo Maher's _Anticolonial Eruptions_.

Feminist epistemologies consider ways in which gender influences knowledge. In this article, I want to consider a particular kind of feminist empiricism that has been called feminist radical empiricism. I am particularly interested in this view's treatment of values as empirical, and consequently up for revision on the basis of empirical evidence. Proponents of this view cite the fact that it allows us to talk about certain things such as racial and gender equality as objective facts: not just whether we (...) have achieved said equality in our society, but whether we are, in fact, all equal. I will raise the concern that the way in which they model the role of values in epistemology may be a problematic idealization of the open-mindedness of human agents. In some cases, resistance to value-change cannot be diagnosed as a failure to respond adequately to evidence. If so, the strategy of empirically testing our values that some feminist radical empiricists suggest may not be as useful a tool for social change as they think. (shrink)

The relation of Hannah Arendt's political theory to Martin Heidegger's philosophy is a fraught topic. This essay explores the basic structure of Arendt's appropriation of Heidegger, the better to defend her theory of political action against oft-repeated charges of elitism and exclusion. In my view, Arendt's critical reading of the canon is deeply indebted to Heidegger, even though her ultimate goal--the recovery of human plurality as a basic and irreducible dimension of politics and the public world--is radically un-Heideggerian in nature.

Open Access: This paper will connect literature on epistemic injustice with literature on victims and perpetrators, to argue that in addition to considering the credibility deficit suffered by many victims, we should also consider the credibility excess accorded to many perpetrators. Epistemic injustice, as discussed by Miranda Fricker, considers ways in which someone might be wronged in their capacity as a knower. Testimonial injustice occurs when there is a credibility deficit as a result of identity-prejudicial stereotypes. However, criticisms of Fricker (...) have pointed out that credibility is part of a more complex system that includes both deficits and excesses. I will use these points to argue that we should look closer at sources of credibility excess in cases of sexual assault. This means that in addition to considering sources of victim blaming by looking at ways in which “ideal” victims are constructed, we also need to consider ways in which “ideal” perpetrators are constructed.

Theodor Adorno once wrote an essay to "defend Bach against his devotees." In this book Dana Villa does the same for Hannah Arendt, whose sweeping reconceptualization of the nature and value of political action, he argues, has been covered over and domesticated by admirers who had hoped to enlist her in their less radical philosophical or political projects. Against the prevailing "Aristotelian" interpretation of her work, Villa explores Arendt's modernity, and indeed her postmodernity, through the Heideggerian and Nietzschean (...) theme of a break with tradition at the closure of metaphysics.Villa's book, however, is much more than a mere correction of misinterpretations of a major thinker's work. Rather, he makes a persuasive case for Arendt as the postmodern or postmetaphysical political theorist, the first political theorist to think through the nature of political action after Nietzsche's exposition of the death of God. After giving an account of Arendt's theory of action and Heidegger's influence on it, Villa shows how Arendt did justice to the Heideggerian and Nietzschean criticism of the metaphysical tradition while avoiding the political conclusions they drew from their critiques. The result is a wide-ranging discussion not only of Arendt and Heidegger, but of Aristotle, Kant, Nietzsche, Habermas, and the entire question of politics after metaphysics. (shrink)

There are two general questions which many views in the philosophy of mathematics can be seen as addressing: what are mathematical objects, and how do we have knowledge of them? Naturally, the answers given to these questions are linked, since whatever account we give of how we have knowledge of mathematical objects surely has to take into account what sorts of things we claim they are; conversely, whatever account we give of the nature of mathematical objects must be accompanied by (...) a corresponding account of how it is that we acquire knowledge of those objects. The connection between these problems results in what is often called "Benacerraf's Problem", which is a dilemma that many philosophical views about mathematical objects face. It will be my goal here to present a view, attributed to Richard Dedekind, which approaches the initial questions in a different way than many other philosophical views do, and in doing so, avoids the dilemma given by Benacerraf's problem.

Objective: This study aims to compare the acoustic vocal analysis results of a group of transgender women relative to those of cisgender women.Methods: Thirty transgender women between the ages of 19 and 52 years old participated in the study. The control group was composed of 31 cisgender women between the ages of 20 and 48 years old. A standardized questionnaire was administered to collect general patient data to better characterize the participants. The vowel /a/ sounds of all participants were collected (...) and analyzed by the Multi-Dimensional Voice Program advanced system.Results: Statistically significant differences between cisgender and transgender women were found on 14 measures: fundamental frequency, maximum fundamental frequency, minimum fundamental frequency, standard deviation of fundamental frequency, absolute jitter, percentage or relative jitter, fundamental frequency relative average perturbation, fundamental frequency perturbation quotient, smoothed fundamental frequency perturbation quotient, fundamental frequency variation, absolute shimmer, relative shimmer, voice turbulence index, and soft phonation index. The mean fundamental frequency value was 159.046 Hz for the cases and 192.435 Hz for the controls.Conclusion: Through glottal adaptations, the group of transgender women managed to feminize their voices, presenting voices that were less aperiodic and softer than those of cisgender women.

Hannah Arendt's rich and varied political thought is more influential today than ever before, due in part to the collapse of communism and the need for ideas that move beyond the old ideologies of the Cold War. As Dana Villa shows, however, Arendt's thought is often poorly understood, both because of its complexity and because her fame has made it easy for critics to write about what she is reputed to have said rather than what she actually wrote. (...) class='Hi'>Villa sets out to change that here, explaining clearly, carefully, and forcefully Arendt's major contributions to our understanding of politics, modernity, and the nature of political evil in our century.Villa begins by focusing on some of the most controversial aspects of Arendt's political thought. He shows that Arendt's famous idea of the banality of evil--inspired by the trial of Adolf Eichmann--does not, as some have maintained, lessen the guilt of war criminals by suggesting that they are mere cogs in a bureaucratic machine. He examines what she meant when she wrote that terror was the essence of totalitarianism, explaining that she believed Nazi and Soviet terror served above all to reinforce the totalitarian idea that humans are expendable units, subordinate to the all-determining laws of Nature or History. Villa clarifies the personal and philosophical relationship between Arendt and Heidegger, showing how her work drew on his thought while providing a firm repudiation of Heidegger's political idiocy under the Nazis. Less controversially, but as importantly, Villa also engages with Arendt's ideas about the relationship between political thought and political action. He explores her views about the roles of theatricality, philosophical reflection, and public-spiritedness in political life. And he explores what relationship, if any, Arendt saw between totalitarianism and the "great tradition" of Western political thought. Throughout, Villa shows how Arendt's ideas illuminate contemporary debates about the nature of modernity and democracy and how they deepen our understanding of philosophers ranging from Socrates and Plato to Habermas and Leo Strauss.Direct, lucid, and powerfully argued, this is a much-needed analysis of the central ideas of one of the most influential political theorists of the twentieth century.

An ad hominem fallacy is committed when an individual employs an irrelevant personal attack against an opponent instead of addressing that opponent’s argument. Many discussions of such fallacies discuss judgments of relevance about such personal attacks, and consider how we might distinguish those that are relevant from those that are not. This paper will argue that the literature on bias and testimony can helpfully contribute to that analysis. This will highlight ways in which biases, particularly unconscious biases, can make ad (...) hominem fallacies seem effective, even when the irrelevance is recognized. (shrink)

This Very Short Introduction explores the philosophical ideas and political theories of Hannah Arendt (1906-1975). As a survivor of the Holocaust, Arendt's life informed her work exploring the meaning and construction of power, evil, totalitarianism, and direct democracy. Through insightful readings of Arendt's best-known works, from The Origins of Totalitarianism (1951) to The Life of the Mind (1978), Dana Villa traces the importance of Arendt's ideas for today's reader. In so doing, Villa explains how Arendt gained world-wide fame (...) with the publication of Origins, and went on to have a distinguished career as a political theorist and public intellectual. A sometimes controversial figure, Arendt is now recognised as one of the most important political thinkers of the twentieth century and her works have become an acknowledged part of the Western canon of political theory and philosophy"--From the publisher.

This essay takes a critical look at the rubric “age of terror,” a rubric which has enjoyed a certain amount of theoretical and philosophical cachet in recent years. My argument begins by noting the continuity between this hypostatization and contemporary “war on terror” rhetoric, a continuity that is, in certain respects, ironic given the politics of the “age of terror” theorists. It then moves—via Machiavelli, Max Weber, and Hannah Arendt—to a consideration of the topics of state violence (on the one (...) hand) and totalitarian terror (on the other). I use Arendt’s theorization of totalitarian terror for a dual purpose: first, to emphasize the gap between totalitarian terror and the more familiar “terror as means”; second, to question the characterization of recent Islamic terrorism as totalitarian in essence. Arendt’s distinctions between violence, terror and totalitarian terror help us avoid the Schmittian logic installed by advocates of the “war on terror” and by a variety of writers anxious to identify a ill-defined and generic “totalitarianism” as the transhistorical and transcultural “other” of liberalism.

Este artículo se enmarca en la macroinvestigación “Barreras psicosociales para la construcción de paz y reconciliación en Medellín y tres municipios de Antioquia”, desarrollado por el Grupo de Investigación en Psicología Sujetos, Sociedad y Trabajo, de la Universidad Pontificia Bolivariana, y pretende comprender los significados que los participantes han construido sobre perdón y reconciliación en el contexto de transición y negociación política del conflicto armado entre el gobierno colombiano y las Fuerzas Armadas Revolucionarias de Colombia. A la luz de la (...) psicología social crítica latinoamericana, emergieron discursos alrededor de las dimensiones individuales, colectivas y sociales del perdón y la reconciliación, las relaciones que se encuentran con la verdad, la justicia, la reparación, el olvido y la memoria; las similitudes y distinciones que encuentran las víctimas entre perdón y reconciliación y la importancia de contextualizar y particularizar estos procesos en función de la desaparición forzada. Los procesos de perdón y reconciliación que se emprendan deben tener como protagonistas a las víctimas, puesto que la intervención del Estado en estos escenarios, cuando hay impunidad, omisiones y encubrimientos por su parte, puede ser contraproducente. Cuando estas se apropian del proceso se producen transformaciones subjetivas y la reconstrucción del tejido social. (shrink)

Resumen En este artículo desarrollo la idea de Gadamer de que el gusto tiene una dimensión más moral que estética. A partir de esta tesis, apoyado en Aristóteles y Paul Ricoeur, trataré de mostrar que, efectivamente, en la experiencia que es el fenómeno del gusto discernimos unas cosas respecto de otras, hacemos distinciones que rebasan con mucho la mera dimensión estética, y nos instalamos en las dimensiones ética y política de la vida humana.In this article I develop Gadamer’s idea on (...) taste having a greater moral dimension than an aesthetic one. From this thesis, and relying on Aristotle and Paul Ricoeur, I aim to demonstrate that it is, in effect, in the experience of the phenomenon of taste where we are able to discern certain things from other; where we make distinctions which go way beyond the mere aesthetic dimension, and place ourselves in the ethical and political dimensions of human life.

In this article we firstly present a Kripke semantics for the description logic ALC which is directly inspired by the semantics for Intuitionistic logic. Moreover, we discuss why a direct translation of this kind of semantics is not adequate in the description logic context and propose a constructive semantics that differs from the previous one by the fact that we impose a condition on the partial order. We also present a tableau calculus which is sound and complete with respect to (...) our semantics. As an application of the calculus we prove that this semantics meets the disjunction property, a key criterion used in assessing whether a logic is constructive. (shrink)

Many critics bemoan the lack of civic engagement in America. Tocqueville's ''nation of joiners'' seems to have become a nation of alienated individuals, disinclined to fulfill the obligations of citizenship or the responsibilities of self-government. In response, the critics urge community involvement and renewed education in the civic virtues. But what kind of civic engagement do we want, and what sort of citizenship should we encourage? In Socratic Citizenship, Dana Villa takes issue with those who would reduce citizenship to (...) community involvement or to political participation for its own sake. He argues that we need to place more value on a form of conscientious, moderately alienated citizenship invented by Socrates, one that is critical in orientation and dissident in practice. Taking Plato's Apology of Socrates as his starting point, Villa argues that Socrates was the first to show, in his words and deeds, how moral and intellectual integrity can go hand in hand, and how they can constitute importantly civic--and not just philosophical or moral--virtues. More specifically, Socrates urged that good citizens should value this sort of integrity more highly than such apparent virtues as patriotism, political participation, piety, and unwavering obedience to the law. Yet Socrates' radical redefinition of citizenship has had relatively little influence on Western political thought. Villa considers how the Socratic idea of the thinking citizen is treated by five of the most influential political thinkers of the past two centuries--John Stuart Mill, Friedrich Nietzsche, Max Weber, Hannah Arendt, and Leo Strauss. In doing so, he not only deepens our understanding of these thinkers' work and of modern ideas of citizenship, he also shows how the fragile Socratic idea of citizenship has been lost through a persistent devaluation of independent thought and action in public life.Engaging current debates among political and social theorists, this insightful book shows how we must reconceive the idea of good citizenship if we are to begin to address the shaky fundamentals of civic culture in America today.

Socially responsible consumption reflects a consumer's political and ethical act. Its measurement is dependent on the socio-economic and cultural context. Consequently, measurement instruments reflecting various behaviour profiles of global consumers have been developed. This study employs a Latin-American-specific measurement instrument to compare socially responsible consumption behaviours in Colombia, Mexico and Peru, countries with the same cultural cluster, that is they reflect a set of values shaped by religion, family, a sense of authority and a nationalist bias in their cultural pattern. (...) The empirical test included confirmatory factorial analysis exercise, factorial invariance analysis and a contrast analysis of variance. The results for the three Latin American countries show the following. (i) The Mexican consumer, compared to the Peruvian and Colombian one, exhibits a stronger tendency to evaluate external practices of corporate social responsibility as a criterion of consumption. (ii) The rationality of the Mexican consumer is better in terms of consumption volume of products, resources and services. Finally, (iii) Peruvian and Mexican consumers (vs. Colombian consumers) exhibit a tendency to assess the responsible practices of companies in labour matters more as a consumption criterion. This study provides empirical evidence of the context-dependent nature of measuring socially responsible consumption. For practitioners, identifying consumer profiles based on the market context enables them to customise goods and services. Moreover, policymakers should implement a sustainable consumption agenda with public policy guidelines tailored to the specific context. (shrink)

Many criticisms of epistemic logic have centered around its use of devices such as idealized knowers with logical omniscience and perfect self-knowledge. One possible response to such criticisms is to say that these idealizations are normative devices, and that epistemic logic tells us how agents ought to behave. This paper will take a different approach, treating epistemic logic as descriptive, and drawing the analogy between its formal models and idealized scientific models on that basis. Treating it as descriptive matches the (...) way in which some philosophers, including one of its founders, Jaako Hintikka, have thought about epistemic logic early in its history. Further, the analogy between the two fields will give us a way to defuse criticisms that see epistemic logic as unrealistic. For example, criticizing models of epistemic logic in which agents know all propositional tautologies as being unrealistic would be like criticizing frictionless planes in physics for being unrealistic. Each one would certainly be an unsuitable model for studying some kinds of phenomena, but is entirely appropriate for others. After outlining the analogy between epistemic and scientific models, we will discuss some ways in which idealizations are used by different research programs in epistemic logic. (shrink)

The changing situation in South Africa and Eastern Europe prompts Charles Villa-Vicencio to investigate the implications of transforming liberation theology into a theology of reconstruction and nation-building. Such a transformation, he argues, requires theology to become an unambiguously interdisciplinary study. This book explores the encounter between theology, on the one hand, and constitutional writing, law-making, human rights, economics, and the freedom of conscience on the other. Placing his discussion in the context of the South African struggle, the author compares (...) this situation to that in Eastern Europe, and the challenge of what is happening in these situations is identified for contexts where "the empire has not yet crumbled.".

Janice Moulton's “The Adversary Method: A Philosophical Paradigm” articulated several criticisms of the popular idea of philosophy as adversarial debate. Moulton criticizes it on epistemic grounds, arguing that philosophy's overreliance on adversarial debate is to the detriment of its goals. Some, notably Trudy Govier, have argued in favor of at least a minimal adversariality, governed by norms of respectful argumentation. This paper suggests that Govier's faith in these norms is misplaced, because it neglects the social circumstances of the arguers. While (...) some authors have argued that politeness and aggression apply differently to those of different genders, this paper extends that analysis to social identities other than gender. In fact, given certain assumptions about the philosophy of language, engagement in polite adversarial debate may not even be possible for people occupying certain social locations. (shrink)

Using a cross‐modal semantic priming paradigm, both experiments of the present study investigated the link between the mental representations of iconic gestures and words. Two groups of the participants performed a primed lexical decision task where they had to discriminate between visually presented words and nonwords (e.g., flirp). Word targets (e.g., bird) were preceded by video clips depicting either semantically related (e.g., pair of hands flapping) or semantically unrelated (e.g., drawing a square with both hands) gestures. The duration of gestures (...) was on average 3,500 ms in Experiment 1 but only 1,000 ms in Experiment 2. Significant priming effects were observed in both experiments, with faster response latencies for related gesture–word pairs than unrelated pairs. These results are consistent with the idea of interactions between the gestural and lexical representational systems, such that mere exposure to iconic gestures facilitates the recognition of semantically related words.

Resumen:El propósito de este ensayo es analizar en qué manera se producen las elaboraciones de conocimiento social, diferenciando el que es propiamente generado como construcción del mundo social del que, de un modo más específico, tiene pretensión de validez científica. Nuestra intención ha sido hacerlo poniendo el fundamento en esa intuición que se caracteriza por ser una forma de acceso al conocimiento cotidiano habitual, natural, sin complejas elaboraciones, intuitivo, en definitiva, que parece regir los posicionamientos, puntos de vista y percepciones (...) en nuestros días; y lo hace, además, de una forma que puede llamarse estética por las propias conceptualizaciones más clásicas, y también porque la estética parece ser uno de los signos de nuestros tiempos que ha quedado incorporado a los mecanismos por los que se produce el conocer intuitivo. Sobre estas bases, concluiremos proponiendo algunas conceptualizaciones que definan y delimiten la validez de las distintas formas de conocimiento social.Palabras clave: intuición; estética; conocimiento; construcción social; verdad.
