While educational settings may be envisioned as safe spaces that facilitate learning, foster creativity, and promote healthy development for youth, research has found that this is not always true for Black girls. Their negative experiences within educational settings are both gendered and racialized, often communicating broader societal perceptions of Black girls that ultimately shape their identity development. Utilizing semi-structured interviews with adolescent Black girls, the current investigation explored Black girls' educational experiences, their meaning making of Black girlhood, and the role (...) of parents in their positive development. By centering Black girls' voices, this study illuminated how Black girls negotiate their multiple marginalized identities and how their identities are shaped by their home and school environments. Findings revealed that Black girls are aware of the difficulties in navigating educational settings for Black girls, but this awareness was coupled with parental support that promoted positive gendered racial identities for Black girls in middle school and high school. This investigation advanced current knowledge of Black girls' identity development and highlighted the protective role of parental socialization. Future research directions and implications are also discussed. (shrink)

Rita Bottino,1 Santosh Nagaraju,2 Vikas Satyananda,2 Hidetaka Hara,2 Martin Wijkstrom,2 Massimo Trucco,1 David KC Cooper2 1Institute of Cellular Therapeutics, Allegheny Health Network, 2Thomas E Starzl Transplantation Institute, Department of Surgery, University of Pittsburgh, Pittsburgh, PA, USA: Diabetes mellitus is increasing worldwide. Type 1 diabetes can be treated successfully by islet allotransplantation, the results of which are steadily improving. However, the number of islets that can be obtained from deceased human donors will never be sufficient to cure more than a very (...) small percentage of patients who might benefit from transplantation. Although there are some differences in glucose metabolism between pigs and humans, the use of pigs could provide an unlimited supply of islets, and the insulin produced would undoubtedly control glucose levels. Transplantation of islets into the portal vein results in islets residing in the liver; however, an early inflammatory response and rejection remain problematic, even when the recipient is receiving immunosuppressive therapy. In the long term, immunosuppressive drugs may exhibit toxicities to patients and specifically harm the islet cells. In contrast, encapsulation techniques provide islets with a physical barrier that prevents antibodies binding to the islet graft while still allowing insulin to be released into the recipient's circulation; in theory, patients receiving encapsulated grafts might not require exogenous immunosuppressive therapy. Nonhuman primates with encapsulated pig islet transplants have remained insulin-independent for several weeks, but long-term efficacy remains uncertain. Furthermore, techniques are now available to knock out genes from the pig and/or insert human genes, thus rendering the antigenic structure of pigs closer to that of humans, and providing protection from the human immune response. Islet transplantation from genetically engineered pigs has been followed by insulin independence in a small number of nonhuman primates for greater than 1 year. Neonatal islets have some advantages over adult islets in that they are easier to isolate and culture, and have the ability to proliferate during the first few months after transplantation. In 2009, the International Xenotransplantation Association set up a group to encourage and advise on clinical trials of pig islet xenotransplantation; this group's guidelines are discussed. Clinical trials of encapsulated pig islets are already under way. Keywords: diabetes, islets, pancreatic, pig, xenotransplantation. (shrink)

Clinical trials of xenotransplantation may begin early in the next decade, with kidneys from genetically modified pigs transplanted into adult humans. If successful, transplanting pig hearts into children with advanced heart failure may be the next step. Typically, clinical trials have a specified end date, and participants are aware of the amount of time they will be in the study. This is not so with XTx. The current ethical consensus is that XTx recipients must consent to lifelong monitoring. While this (...) presents challenges to the right to withdraw in the adult population, additional and unanswered questions also linger in the paediatric population. In paediatric XTx, parents or guardians consent not only to the initial treatment of the child but also to lifelong monitoring, thus making a decision whose consequences will remain present as the child develops the capacity for assent, and finally the capacity for informed consent or refusal. This article presents and evaluates unanswered paediatric ethical questions in regard to the right to withdraw from XTx follow-up in the paediatric population. (shrink)

NEITHER in the scholarly nor in the philosophical literature on Aristotle does his account of friendship occupy a very prominent place. I suppose this is partly, though certainly not wholly, to be explained by the fact that the modern ethical theories with which Aristotle’s might demand comparison hardly make room for the discussion of any parallel phenomenon. Whatever else friendship is, it is, at least typically, a personal relationship freely, even spontaneously, entered into, and ethics, as modern theorists tend to (...) conceive it, deals rather with the ways in which people are required to regard, and behave toward, one another, than with the organization of their private affairs. To the extent, then, that one shares this modern outlook one will tend to neglect, or treat merely as an historical curiosity, Aristotle’s efforts to define friendship and to place it within the framework of human eudaimonia, the theory of which is central to moral philosophy as he understands it. Yet in the Nicomachean Ethics the two books on φιλία make up nearly a fifth of the whole, and this seems to me a fair measure of the importance of this subject to the complete understanding both of Aristotle’s overall moral theory and even of many of the more circumscribed topics to which so much scholarly and philosophical attention has been devoted. If, as I suggest, the failure of commentators to appreciate its importance is partly the effect of distortions produced by the moral outlook that has predominated in modern moral philosophy, the careful study of these books may help to free us from constricting prejudices and perhaps even make it possible to discover in Aristotle a plausible and suggestive alternative to the theories constructed on the narrower base characteristic of recent times.

Outstanding translations by leading contemporary scholars--many commissioned especially for this volume--are presented here in the first single edition to include the entire surviving corpus of works attributed to Plato in antiquity. In his introductory essay, John Cooper explains the presentation of these works, discusses questions concerning the chronology of their composition, comments on the dialogue form in which Plato wrote, and offers guidance on approaching the reading and study of Plato's works. Also included are concise introductions by Cooper (...) and Hutchinson to each translation, meticulous annotation designed to serve both scholar and general reader, and a comprehensive index. This handsome volume offers fine paper and a high-quality Smyth-sewn cloth binding in a sturdy, elegant edition. (shrink)

This book brings together twenty-three distinctive and influential essays on ancient moral philosophy--including several published here for the first time--by the distinguished philosopher and classical scholar John Cooper.

Philosophers have recently revived the study of the ancient Greek topics of virtue and the virtues—justice, honesty, temperance, friendship, courage, and so on as qualities of mind and character belonging to individual people. But one issue at the center of Greek moral theory seems to have dropped out of consideration. This is the question of the unity of virtue, the unity of the virtues. Must anyone who has one of these qualities have others of them as well, indeed all of (...) them—all the ones that really do deserve to be counted as virtues? Even further, is there really no set of distinct and separate virtuous qualities at all, but at bottom only a single one—so that the person who has this single condition of “virtue” is entitled also to the further descriptions “honest” and “well-controlled” and “just” and “friendly” and “courageous” and “fostering” and “supportive,” and so on, as distinguishable aspects or immediate effects of his unitary “virtue”?

I discuss the division of the soul in plato's "republic". i concentrate on the arguments and illustrative examples given in book iv, but i treat the descriptions of different types of person in viii-ix and elsewhere as further constituents of a single, coherent theory. on my interpretation plato distinguishes three basic kinds of motivation which he claims all human beings regularly experience in some degree. reason is itself the immediate source of certain desires. in addition, there are appetitive and also--quite (...) distinct from either of the other two--competitive motivations.

We propose a naturalistic version of the “guesser–knower” paradigm in which the experimental subject has an opportunity to choose which individual to follow to a hidden food source. This design allows nonhumans to display the attribution of knowledge to another conspecific, rather than a human, in a naturalistic context (finding food), and it is readily adapted to different species.

Knowledge, Nature, and the Good brings together some of John Cooper's most important works on ancient philosophy. In thirteen chapters that represent an ideal companion to the author's influential Reason and Emotion, Cooper addresses a wide range of topics and periods--from Hippocratic medical theory and Plato's epistemology and moral philosophy, to Aristotle's physics and metaphysics, academic scepticism, and the cosmology, moral psychology, and ethical theory of the ancient Stoics.Almost half of the pieces appear here for the first time (...) or are presented in newly expanded, extensively revised versions. Many stand at the cutting edge of research into ancient ethics and moral psychology. Other chapters, dating from as far back as 1970, are classics of philosophical scholarship on antiquity that continue to play a prominent role in current teaching and scholarship in the field. All of the chapters are distinctive for the way that, whatever the particular topic being pursued, they attempt to understand the ancient philosophers' views in philosophical terms drawn from the ancient philosophical tradition itself.Through engaging creatively and philosophically with the ancient texts, these essays aim to make ancient philosophical perspectives freshly available to contemporary philosophers and philosophy students, in all their fascinating inventiveness, originality, and deep philosophical merit. This book will be treasured by philosophers, classicists, students of philosophy and classics, those in other disciplines with an interest in ancient philosophy, and anyone who seeks to understand philosophy in philosophical terms.

As it is currently understood, the notion of autonomy, both as something that belongs to human beings and human nature, as such, and also as the source or basis of morality , is bound up inextricably with the philosophy of Kant. The term “autonomy” itself derives from classical Greek, where it was applied primarily or even exclusively in a political context, to civic communities possessing independent legislative and self-governing authority. The term was taken up again in Renaissance and early modern (...) times with similar political applications, but was applied also in ecclesiastical disputes about the independence of reformed churches from the former authority in religious matters of the church of the Roman popes. Kant's innovation consisted in conceiving of individual rational persons, as such, as lawgivers or legislators to themselves, and to all rational beings , for their individual modes of behavior. For Kant, rational beings possess a power of legislating for themselves individually, according to which they each set their own personal ends and subject that selection, and their pursuit of the ends in question, to a universal principle, which is expressed in Kant's categorical imperative. The categorical imperative requires that one set one's own ends only within a framework that would warrant acceptance by all other such beings. (shrink)

The first part of the chapter translates and discusses, section by section, Metaphysics Α 10. The second part rveiews in retrospect Aristotle's intentions in Metaphysics Α as a whole, and the progress of his argument through the 10 chapters of the book. It is Aristotle's intention to search for the first principles and causes of being, by reviewing and examining the opinions of his predecessors on this subject. A distinction must be made between Aristotle's report of his predecessors' opinions and (...) his critical discussion of the difficulties he thinks their views involve; at the end of the book Aristotle reminds us that we need to mull over these difficulties for ourselves: this is the programme set for Book B.

Recent scholarship has steadily been opening up for philosophical study an increasingly wide range of the philosophical literature of antiquity. We no longer think only of Socrates, Plato and Aristotle, and their pre-Socratic forebears, when someone refers to the views of the ancient philosophers. Julia Annas has been one of the philosophers most closely engaged in the renewed study of Hellenistic philosophy over the past fifteen years, enabling herself and other scholars to acquire the necessary ground-level knowledge of the widely-dispersed (...) texts and the problems of interpretation—both historical and philosophical—that they present. In her new book she takes the next step. She presents to the general philosophical public of today an extended reconstruction of the systems of moral philosophy that were developed and pitted in competition with one another during the period when refinement and professionalism were at their height in Greek philosophy—between the end of the 4th and the middle of the 1st centuries B.C. These include the moral philosophies of Epicurus and his followers, several generations of Stoics, sceptical philosophers both Academic and Pyrrhonian, and the “hybrid” theories put together by Antiochus of Ascalon and other Stoic-influenced philosophers as part of the modernizing revival of Aristotelian ethical thought that took place in the 1st century B.C. She finds significant commonalities among these otherwise very disparate theories, and much of the book is devoted to examining these and showing how the conception of ethics and morality that is common to the ancient theorists compares with and differs from what we are familiar with in modern and contemporary theory. She traces these commonalities back to Aristotle in his ethical treatises, and accordingly includes Aristotle’s theory as one among those to be examined—indeed, in a significant sense as the intellectual father or grandfather of the rest of them. She leaves Plato’s dialogues out of account, and she has nothing to say about ethics and moral philosophy in the revived Platonism that gradually came to dominate philosophical thought in later antiquity. Her book, then, is a book about the structure and content of ancient ethical theory during the Hellenistic period, the period when Greek philosophy was at its high-point in professionalism and sophistication.
