Exposure to pesticides during infancy is associated with numerous adverse health outcomes. The assessment of knowledge and perception of pesticides exposure and risk among children has not been thoroughly studied. The aim of the study was to evaluate the reliability and validity of a questionnaire that measures the knowledge and perception of exposure to organophosphate pesticides among rural schoolchildren. The questionnaire was administered to 151 schoolchildren between 9 and 13years from four Chilean rural schools. An internal consistency analysis of the (...) ordinal alpha coefficient and a polychoric factor analysis for categorical data were used. The results show that the ordinal alpha was 0.95. Polychoric matrices of rotated components show the 17 questions summarized pesticide knowledge in five factors extracted after promax rotation. This factorial model explains 56.3% of the variance. The questions were grouped as follows: knowledge about pesticides ; knowledge of health effects related to pesticides exposure ; pesticide exposure through the growing of fruits and vegetables ; perception and action against pesticides exposure at school ; and perception and action against pesticides exposure at home. The questionnaire provides a useful tool for examining pesticide exposure in agricultural regions, allowing younger community members to participate. (shrink)

This collective paper on radicalization and violent extremism part of the ‘Philosophy of education in a new key’ initiative by Educational Philosophy and Theory brings together some of the leading contemporary scholars writing on the most pressing epistemological, ethical, political and educational issues facing post-9/11 scholarship on radicalization and violent extremism. Its overall aim is to move beyond the ‘conventional wisdom’ associated with this area of scholarly research best represented by its many slogans, metaphors and other thought-terminating clichés. By providing (...) conceptual lenses on issues previously compartmentalized primarily [or even exclusively] in security and intelligence studies or at the fringes of scholarly interest, radicalization and violent extremism turn out to be much more complex than ‘radicalization studies’ has been eager to acknowledge.

Legal theorists are familiar with John Finnis's book Natural Law and Natural Rights, but usually overlook his interventions in US constitutional debates and his membership of a group of conservative Catholic thinkers, the 'new natural lawyers', led by theologian Germain Grisez. In fact, Finnis has repeatedly advocated conservative positions concerning lesbian and gay rights, contraception and abortion, and his substantive moral theory derives from Grisez. Bamforth and Richards provide a detailed explanation of the work of the new natural lawyers within (...) and outside the Catholic Church - the first truly comprehensive explanation available to legal theorists - and criticize Grisez's and Finnis's arguments concerning sexuality and gender. New natural law is, they argue, a theology rather than a secular theory, and one which is unappealing in a modern constitutional democracy. This book will be of interest to legal and political theorists, ethicists, theologians and scholars of religious history. (shrink)

Political violence in the form of wars, insurgencies, terrorism and violent rebellion constitutes a major human challenge. C. A. J. Coady brings a philosophical and ethical perspective as he places the problems of war and political violence in the frame of reflective ethics. In this book, Coady re-examines a range of urgent problems pertinent to political violence against the background of a contemporary approach to just war thinking. The problems examined include: the right to make war and conduct war, terrorism, (...) revolution, humanitarianism, mercenary warriors, the ideal of peace and the right way to end war. Coady attempts to vindicate the contemporary relevance of the just war tradition to current problems without applying the tradition in a merely mechanical or uncritical fashion. (shrink)

Mereotopology is a theory of connected parts. The existence of boundaries, as parts of everyday objects, is basic to any such theory; but in classical mereotopology, there is a problem: if boundaries exist, then either distinct entities cannot be in contact, or else space is not topologically connected . In this paper we urge that this problem can be met with a paraconsistent mereotopology, and sketch the details of one such approach. The resulting theory focuses attention on the role of (...) empty parts, in delivering a balanced and bounded metaphysics of naive space. (shrink)

People disagree about whether “moral facts” are objective facts like mathematical truths (moral realism) or simply products of the human mind (moral antirealism). What is the impact of different meta-ethical views on actual behavior? In Experiment 1, a street canvasser, soliciting donations for a charitable organization dedicated to helping impoverished children, primed passersby with realism or antirealism. Participants primed with realism were twice as likely to be donors, compared to control participants and participants primed with antirealism. In Experiment 2, online (...) participants primed with realism as opposed to antirealism reported being willing to donate more money to a charity of their choice. Considering the existence of non-negotiable moral facts may have raised the stakes and motivated participants to behave better. These results therefore reveal the impact of meta-ethics on everyday decision-making: priming a belief in moral realism improved moral behavior. (shrink)

Seneca the Younger's tragedies are adaptations from the Greek. C. A. J. Littlewood emphasizes the place of these plays in the Latin literature and in the philosophical context of the reign of the emperor Nero. Stoics dismissed public reality as theatre, as illusion. The artificiality of Senecan tragedy, the consciousness that its own dramatic worlds are literary constructs, responds to this contemporary philosophical perception.

In this paper we continue an ongoing dialogue that has as its goal the critical appraisal of theoretical perspectives on culture and health, in an effort to move forward scholarship on culture and health. We draw upon a programme of scholarship to explicate theoretical tensions and challenges that are manifest in the discourses on culture and health and to explore the possibilities Bourdieu's theoretical perspective offers for reconciling them. That is, we hope to demonstrate the need to move beyond descriptions (...) ‘of’ culture to an understanding of cultures as dynamic, and to show ways cultural practices create contexts that have the potential to foster or impede health.In our early research, largely undertaken in Canada's multicultural context, we sought to make visible the ways in which culture shaped conceptions of health and influenced health practices of immigrant groups. In recent years this focus has expanded to include populations that reflect the cultural and social diversity of our region. From the outset we attempted to move towards a conception of culture as negotiated, unifying, transformative and dynamic. While this position continues to hold appeal we are continually reminded that, despite our leanings towards constructivism, there is salience to the notion of culture as having enduring elements. It is this tension between the view of culture as embodied and enduring and culture as constructed and dynamic that we seek to examine.We explore whether Bourdieu's theoretical perspective offers promise for reconciling these apparently competing views. Using exemplars from our research we share insights that Bourdieu's work has offered to our analyses, thereby enabling us to move towards a view of culture that holds in tension these apparently contradictory positions of culture as both essence (albeit unstable, negotiated) and constructed.

It is common to assume that if Locke is to be regarded as a consistent epistemologist he must be read as holding that either ideas are the objects of perception or that (physical) objects are. He must either be a direct realist or a representationalist. But perhaps, paradoxical as it at first sounds, there is no reason to suppose that he could not hold both to be true. We see physical objects and when we do so we have ideas. We (...) see or hear birds and bells but we also have visual and auditory ideas of birds and bells. This suggestion is explored through examination of what Locke says about perception in his Elements of Natural Philosophy and the accounts offered both by Locke in the Essay Concerning Human Understanding and by some of Locke's successors.

Recently at least two papers1,2have appeared that look at cancer from an evolutionary perspective. That cancer has a negative effect on fitness needs no argument. However, cancer origination is not an isolated process, but the potential for it is linked in diverse ways to other genetically determined developmental events, complicating the way selection acts on it, and through it on the evolution of development. The two papers take a totally different line. Kavanagh argues that anti‐cancer selection has led to developmental (...) constraints. Leroi et al. argue that cancer is a side‐effect of recent evolutionary changes that usually will disappear over time through anti‐cancer selection. Here we place the papers in a wider perspective, and in so doing discuss various alternative developmental links cancer may have together with their evolutionary implications.

This is an encyclopedia entry (for the IVR Encyclopedia of legal and political philosophy) covering John Rawls. It aims to provide a general but not superficial introduction to Rawls's theory of justice, justice as fairness.

William Burnside was one of the three most important algebraists who were involved in the transformation of group theory from its nineteenth-century origins to a deeper twentieth-century subject. Building on work of earlier mathematicians, they were able to develop sophisticated tools for solving difficult problems. His works are of enormous historical importance; they remain also a source of inspiration and information. The works of his contemporaries, such as Klein, Frobenius, Schur, have been published as also have the works of his (...) immediate successors such as Phillip Hall. All of Burnside's papers are reproduced here, organized chronologically and with a detailed bibliography. Walter Feit has contributed a foreword, and a collection of introductory essays are included to provide a commentary on Burnside's work and set it in perspective along with a modern biography that draws on archive material. This is the first reference volume of Burnside's collected papers, enhanced by a series of critical essays on his work, and is important for group theorists and historians and philosophers of mathematics and fills the gap in this area of literature.

This volume collects Late Ancient, Byzantine and Medieval appropriations of Aristotle's Posterior Analytics, addressing the logic of inquiry, concept formation, the question whether metaphysics is a science, and the theory of demonstration.

Phantom limb experiences demonstrate an unexpected degree of fragility inherent in our self-perceptions. This is perhaps most extreme when congenitally absent limbs are experienced as phantoms. Aplasic phantoms highlight fundamental questions about the physiological bases of self-experience and the ontogeny of a physical, embodied sense of the self. Some of the most intriguing of these questions concern the role of mirror neurons in supporting the development of self–other mappings and hence the emergence of phantom experiences of congenitally absent limbs. In (...) this paper, we will examine the hypothesis that aplasic phantom limb experience is the result of an ontogenetic interplay between body schemas and mirror neuron activity and that this interplay is founded on embedding in a social context. Phantom limb experience has been associated with the persistence of subjective experience of a part of the body after deafferentation through surgical or traumatic removal. We maintain that limited association is inconsistent with the extent to which phantom limb experience is reported by aplasic individuals. (shrink)

The crux of this book is expressed in one short sentence from the Preface: 'Unity is a fundamental part of our experience, something that is crucial to its phenomenology' [p.xii], and the crux of this sentence is that the unity of consciousness is not a matter of phenomenal relations existing between distinct experiences – the received view [p.17], but the existence of relations between the contents of experiences – the one experience view [p.25ff]. In its simplest form Tye's claim is (...) that: all our conscious states, whether visual, auditory, olfactory, tactual or gustatory, whether imagistic or emotional are experienced concurrently; they 'are phenomenologically unified ... [and] ... Phenomenological unity is a relation between qualities represented in experience, not between qualities of experiences. [p.36]. (shrink)

The primary aim of this study was to investigate the relation between self-perceived executive functions and the school achievement of young adolescents, while controlling for parental education and sex. We specifically focused on executive aspects of daily life behavior and the higher-order EFs, as measured with self-report, rather than on the more basic EFs which have been the primary focus of prior investigations. In two independent samples of sixth graders, students evaluated their EFs on a self-report questionnaire, the Amsterdam Executive (...) Functioning Inventory. School achievement in the domains of mathematics and reading comprehension were evaluated with nationally used, norm-based achievement tests. Results revealed that the self-perceived EFs of young adolescents were significantly correlated with their school achievement in both study samples. School achievement was also correlated with the level of parental education, but the factor sex did not have such influence. In study 1, self-perceived EFs explained additional variance in school achievement, while controlling for parental education and sex. In study 2, this was only the case for the most robust measure of school achievement, i.e., the end-of-primary-school final achievement test. Furthermore, besides the relation with achievement tests, we also found a relation between self-perceived EFs and teacher ratings behavioral problems in the classroom. Together, our findings imply that young students can properly reflect on the effectiveness and appropriateness of their EFs in a way that is relevant to their academic achievement and classroom behavior. The findings underscore the importance of considering the development of EFs and parental education in the evaluation of academic achievements in early adolescence. (shrink)
