The literature on public perceptions of, and attitudes towards, nanotechnology used in the agrifood sector is reviewed. Research into consumer perceptions and attitudes has focused on general applications of nanotechnology, rather than within the agrifood sector. Perceptions of risk and benefit associated with different applications of nanotechnology, including agrifood applications, shape consumer attitudes, and acceptance, together with ethical concerns related to environmental impact or animal welfare. Attitudes are currently moderately positive across all areas of application. The occurrence of a negative (...) or positive incident in the agri-food sector may crystallise consumer views regarding acceptance or rejection of nanotechnology products. •Acceptance of agrifood nanotechnology based on perceptions of risk, benefit and ethics.•Attitudes towards nanotechnology in general are currently moderately positive.•Occurrence of a major nanotechnology-related "event" may crystallise consumer attitude.

The term "stakeholder engagement" has gained increasing prominence over the last few years. This prominence is fueled by a range of issues such as an increased dissatisfaction with business's focus on stockholder/shareholder interests and the demands for greater transparency from business following major business scandals. A perceived response to this issue in South Africa has been the inclusion of guidelines on stakeholder engagement in the King II Report on Corporate Governance. Despite this growing interest, there has not been clarity (...) on how companies engage with their stakeholders and specifically with how they identify and prioritize their stakeholders. The study sought to establish the reporting practices of South African business in relation to stakeholder identification and prioritization through a content analysis of their annual reports. The findings are discussed and recommendations on the two aspects of stakeholder engagement presented. (shrink)

The majority of the twenty-two essays of this festschrift start from the assumption that after Kant's critique and Nietzsche's work metaphysics has become problematic. About half of the articles concern Nietzsche's thought. This is understandable inasmuch as Wolfgang Müller-Lauter, to whom this festschrift is dedicated, devoted much of his work to Nietzsche.

Objective: To explore the accounts and perspectives of junior doctors who were offered an HIV test by their employing National Health Service (NHS) trust and discuss ethical issues posed by this new policy. Design: Qualitative in-depth interview study. Setting: 4 NHS hospital trusts. Participants: 24 junior doctors who had been offered an HIV test as part of their pre-employment occupational health checks. Results: The manner in which HIV tests were offered to junior doctors varied both between and within the NHS (...) trusts. Overall, the doctors were highly critical of the way the HIV test was offered. Recurrent themes surrounding a lack of discussion and information regarding the indications for the test and implications of a positive result influenced the the doctors’ perception of their experiences. As a consequence of the shortcomings of how the test was offered, most of the doctors held the misperception that HIV testing was mandatory and many felt unable to decline the test. The majority of doctors referred to patient protection as adequate justification for being offered an HIV test. Conclusions: Junior doctors offered an HIV test under new Department of Health occupational health guidance were disparaging about how the test was offered. The findings of this study affect thousands of junior doctors in the UK, and the impact of these results is extensive. Participants’ suggestions regarding how the process of offering an HIV test can be improved are discussed and ethical issues regarding the new Department of Health policy are highlighted. (shrink)

The Wisdom to Doubt is a major contribution to the contemporary literature on the epistemology of religious belief.

This study empirically examines the association between certain director characteristics and the extent of voluntary audit committee disclosure in annual reports. Results suggest that Singapore's publicly traded firms are more likely to voluntarily disclose audit committee related information as: the number of board members increases; different individuals occupy the roles of CEO and board chairperson; and the proportion of independent directors serving on the board increases. Findings, however, fail to show any association between the amount of voluntary audit committee disclosure (...) and the percentage of executive directors' ownership. Documented findings are of interest and benefit to various parties including regulators, corporate governance reformists, and corporate management. For instance, findings imply that a positive by-product of implementing major corporate governance reforms currently championed by corporate governance reformists will be an increase in audit committee disclosures. As a result, there will be less pressure on regulators to develop, introduce, and enforce mandatory audit committee disclosures that may be potentially intrusive to a firm's management. (shrink)

Coexistence between livestock grazing and carnivores in rangelands is a major challenge in terms of sustainable agriculture, animal welfare, species conservation and ecosystem function. Many effective non-lethal tools exist to protect livestock from predation, yet their adoption remains limited. Using a social-ecological transformations framework, we present two qualitative models that depict transformative change in rangelands grazing. Developed through participatory processes with stakeholders from South Africa and the United States of America, the models articulate drivers of change and the essential (...) pathways to transition from routine lethal management of carnivores towards mutually beneficial coexistence. The pathways define broad actions that incorporate multiple values in grazing systems including changes to livestock management practices, financial support, industry capacity building, research, improved governance and marketing initiatives. A key finding is the new concept of ‘Predator Smart Farming’, a holistic and conscientious approach to agriculture, which increases the resilience of landscapes, animals and rural livelihoods. Implementation of these multiple pathways would lead to a future system that ensures thriving agricultural communities, secure livelihoods, reduced violence toward animals, and landscapes that are productive and support species conservation and coexistence.

Background Residual dried blood spots (rDBS) from newborn screening programmes represent a valuable resource for medical research, from basic sciences, through clinical to public health. In Hong Kong, there is no legislation for biobanking. Parents’ view on the retention and use of residual newborn blood samples could be cultural-specific and is important to consider for biobanking of rDBS. Objective To study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese (...) parents. Methods A mixed-method approach was used to study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese parents of children 0–3 years or expecting parents through focus groups (8 groups; 33 participants) and a survey (n = 1012, 85% mothers) designed with insights obtained from the focus groups. We used framework analysis to summarise the themes as supportive factors, concerns and critical arguments for retention and secondary use of rDBS from focus group discussion. We used multiple logistic regression to assess factors associated with support for retention and secondary use of rDBS in the survey. Results Both in focus groups and survey, majority of parents were not aware of the potential secondary use of rDBS. Overall secondary use of rDBS in medical research was well accepted by a large proportion of Hong Kong parents, even if all potential future research could not be specified in a broad consent. However parents were concerned about potential risks of biobanking rDBS including leaking of data and mis-use of genetic information. Parents wanted to be asked for permission before rDBS are stored and mainly did not accept an “opt-out” approach. The survey showed that parents born in mainland China, compared to Hong Kong born parents, had lower awareness of newborn screening but higher support in biobanking rDBS. Higher education was associated with support in rDBS biobanking only among fathers. Conclusion Long-term storage and secondary use of rDBS from newborn screening for biomedical research and a broad consent for biobanking of rDBS are generally acceptable to Hong Kong parents given their autonomy is respected and their privacy is protected, highlighting the importance of an accountable governance and a transparent access policy for rDBS biobanks.

Historians of seventeenth-century science have frequently asserted that Kepler's laws of planetary motion were largely ignored between the time of their first publication and the publication of Newton's Principia . In fact, however, they were more widely known and accepted than has been generally recognized.Kepler's ideas were, indeed, rather slow in establishing themselves, and until about 1630 there are few references to them in the literature of the time. But from then onwards, interest in them increased fairly rapidly. In particular, (...) the principle of elliptical orbits had been accepted by most of the leading astronomers in France before 1645 and in England by about 1655. It also received quite strong support in Holland.The second law had a more chequered history. It was enunciated in its exact form by a few writers and was used in practice by some others without being explicitly formulated, but the majority, especially after 1645, preferred one or another of several variant forms which were easier to use but only approximately correct. The third law attracted less interest than the others, chiefly perhaps because it had no satisfactory theoretical basis, but it was correctly stated by at least six writers during the period under review.Between about 1630 and 1650 Kepler's Epitome Astronomiae Copernicanae was probably the most widely read work on theoretical astronomy in northern and western Europe, while his Rudolphine Tables, which were based upon the first two laws, were regarded by the majority of astronomers as the most accurate planetary tables available.Kepler's work certainly did not receive all the recognition it deserved, but the extent to which it was neglected has been much exaggerated.

This is the second edition of a very imaginative collection of readings in aesthetics from Plato to the present. In this second edition, seven selections have been deleted and fifteen new selections have been added to greatly enhance its usefulness to beginning students in aesthetics. Additional readings on artistic creation and drama have been provided and a number of illustrations of works by Raphael, Giotto, Matisse, Dürer, Brancusi, Henry Moore, et al. have been included this time to illustrate relevant textual (...) materials. As in the first edition, the author's primary intention is to establish the field of aesthetics as having the same integrity and adventuresomeness as other areas of philosophical inquiry and debate. With this goal in view, he has organized the readings around "certain sets of basic problems that still seem worth debating and attempting to solve." Each section is centered around specific problems and issues in aesthetics, beginning with the broadest question, "What is Art?," and moving on to such issues as the nature of the various art forms, the nature of tragedy, the problem of response to art and, finally, the nature and goal of art criticism. Various readers and teachers in aesthetics no doubt, will find fault with or gaps in his selections of readings. But laying aside such parochial matters as ideology and personal taste, this volume puts in the hands of the student of aesthetics a compendium of essays on the major issues and areas of concern in aesthetics which can easily be supplemented by use of a xerox machine. The editor has included such scholarly aids as a brief introduction to each section, interpretative and cross-referential footnotes and a minimal bibliography.--J. B. L. (shrink)

The main purpose of this volume is the admirable one of preparing a series of volumes on the global history of philosophy. While the effort falls far short of what we might have hoped for, it must be judged as a good beginning in this area. The volume begins with a listing of introductory works dealing with the philosophies of major cultures: India, China, Japan, Islam, Russia and Latin America. The difficulties of launching into a study of world philosophy (...) become apparent at this point; the bibliographical categories are a mixture of geographical areas and religio-cultural traditions which overlap land-boundaries. The authors now depart from the geographical-cultural schema by organizing the material along a mixture of historical and topical structures--all taken from the western context. The list of historical segments include: Classical Period, Pan-Hellenistic-Bactrian Period, Early "Medieval" Period, The Great Summas, Late "Medieval" Period, "Renaissance" Period, Transition to the Modern Period, and Modern Period. The book concludes with a section dedicated to works concerning the Scientific Revolution and the Philosophy of International Law. In a pocket on the back cover the reader will find two large fold-outs which present "A Synchronological Chart to the Global History of Philosophy."--J. B. L. (shrink)

Background: Discussions about medical errors facilitate professional learning for physicians and may provide emotional support after an error, but little is known about physicians’ attitudes and practices regarding error discussions with colleagues.Methods: Survey of faculty and resident physicians in generalist specialties in Midwest, Mid-Atlantic and Northeast regions of the US to investigate attitudes and practices regarding error discussions, likelihood of discussing hypothetical errors, experience role-modelling error discussions and demographic variables.Results: Responses were received from 338 participants . In all, 73% of (...) respondents indicated they usually discuss their mistakes with colleagues, 70% believed discussing mistakes strengthens professional relationships and 89% knew at least one colleague who would be a supportive listener. Motivations for error discussions included wanting to learn whether a colleague would have made the same decision , wanting colleagues to learn from the mistake and wanting to receive support . Given hypothetical scenarios, most respondents indicated they would likely discuss an error resulting in no harm , minor harm or major harm . Fifty-seven percent of physicians had tried to serve as a role model by discussing an error and role-modelling was more likely among those who had previously observed an error discussion .Conclusions: Most generalist physicians in teaching hospitals report that they usually discuss their errors with colleagues, and more than half have tried to role-model discussions. However, a significant number of these physicians report that they do not usually discuss their errors and some do not know colleagues who would be supportive listeners. (shrink)

Ventricular Fibrillation is responsible for a majority of sudden cardiac death, but little is known about how ventricular tachycardia (VT) degenerates into ventricular fibrillation. Several clinical studies focused only on preventing VT with a class III antiarrhythmic drug resulted in many deaths. Our simulations investigate the interactions between an antiarrhythmic drug likely to suppress a VT and a Figure 8 reentry. A parameter AAR is introduced to increase the action potential duration and therefore simulate various Class III drugs. Simulations are (...) ran under several conditions (phases of the reentry, values of AAR, durations). They show that a VT can be suppressed whatever the phase of the reentry but it strongly depends on the duration of the effect. It confirms that a drug which can suppress a reentry can also worsen it. It also shows a great variety of activation patterns and thus the complexity of antiarrhythmic drugs effects. Simulations also demonstrate that suppressing VT is an increasing function of AAR.

Tommie Shelby has offered an influential, carefully stated, and well-argued set of objections to any volitional analysis of racism (VAR) as consisting centrally in certain forms of race-based disregard. Here I hope to defend aspects of VAR by analyzing, evaluating, and sometimes countering several of his major contentions, which have stood unchallenged in the literature over more than two decades. First, I sketch and respond to his Methodological objection to VAR, which criticizes VAR's reliance on language and linguistic intuitions; (...) then to a Psychological objection, which suggests that VAR implausibly distances an agent's intentions from her beliefs; and, finally, to a Psychopathological objection, which holds that VAR requires treating as unproblematic some psychological states better seen as aberrant. The following section treats three subtle counterexamples Shelby uses to challenge VAR's core contentions about what's necessary and what's sufficient for racism. I close with some gestures toward what I see as a promising approach, very different from his, to studying these topics. (shrink)

In biological electron transport the spin, and thus the magnetic property of electrons, is neglected. Furthermore, no attention is paid to the fact that the great majority of biologically important molecules are chiral, and during excitation a magnetic moment is induced in them. It is shown, both theoretically and experimentally, that the magnetic moment of the electron and the magnetic transition moment of the optically active molecules may interact. The main consequences of such an interaction are a higher probability of (...) the occurrence of optically active molecules in triplet states, and the polarization of transported electrons. (shrink)

This is a highly original and readable work by an eminent teacher of philosophy and religion and a very gifted writer who is able to discuss the relationship between Indian and Western scholars without being either doctrinaire or dull. He has determined the exact position of Bengal Vaisnavism in relation to other systems of Indian philosophy, especially Advaita Vedanta, by bringing out important points of agreement and disagreement between it and them. After arguing in the first chapter that metaphysics is (...) logically prior to epistemology, he provides a psychological analysis of knowledge according to the three main spokesmen for Vedänta. Subsequent chapters treat God as the ground of physical and spiritual reality, causation, Krsna and his incarnations, and Bhakti or devotional faith as a means of God-realization. Two other chapters which merit a mention provide a comparative analysis of Bengal Vaisnavism and Kierkegaardian existentialism and of Vaisnavism and Christianity. While Kierkegaard and the Vaisnava spokesmen do differ at many points, they also share a good many ideas in common with respect to their respective understandings of God, the nature of man, and man's relationship to the outer world. This is one of the better books written on Indian Vedanta by a contemporary Indian scholar and appropriate for both specialist and layman who might wish a readable and comprehensive but manageable discussion of one of the major schools of Indian philosophy.--J.

Individuals with major depressive disorder (MDD) often ruminate about past experiences, especially those with negative content. These repetitive thoughts may interfere with cognitive processes related to attention and conflict monitoring. However, the temporal nature of these processes as reflected in event-related potentials (ERPs) has not been well-described. We examined behavioral and ERP indices of conflict monitoring during a modified flanker task and the allocation of attention during an attentional blink (AB) task in 33 individuals with MDD and 36 healthy (...) controls, and whether their behavioral performance and ERPs varied with level of rumination. N2 amplitude elicited by the flanker task was significantly reduced in participants with MDD compared to healthy controls. Level of self-reported rumination was also correlated with N2 amplitude. In contrast, P3 amplitude during the AB task was not significantly different between groups, nor was it correlated with rumination. No significant differences were found in behavioral task performance measures between groups or by rumination levels. These findings suggest that rumination in MDD is associated with select deficits in cognitive control, particularly related to conflict monitoring. (shrink)

The Drosophila salivary gland has emerged as an outstanding model system for the process of organ formation. Many of the component steps, from initial regional specification through cell specialization and morphogenesis, are known and many of the genes required for these different processes have been identified. The salivary gland is a relatively simple organ; the entire gland comprises of only two major cell types, which derive from a single contiguous primordium. Salivary cells cease dividing once they are specified, and (...) organ growth is achieved simply by an increase in size of individual cells, thus eliminating concerns about the potential unequal distribution of determinants during mitosis. Drosophila salivary glands form by the same cellular mechanisms as organs in higher organisms, including regulated cell shape changes, cell intercalation and directed cell migration. Thus, learning how these events are coordinated for tissue morphogenesis in an organism for which the genetic and molecular tools are unsurpassed should provide excellent paradigms for dissecting related processes in the more intricate organs of more complicated species.

Students of philosophy, East and West, will be benefited greatly by this reprint of Professor Raju's pioneering study of comparative philosophy, which is the outgrowth of a series of lectures presented in Saugor University during 1955. Even for comparative philosophy, man must be the leitmotif, the common denominator for analyzing and interpreting the diversity of philosophical traditions. In his attempt to contribute to the "sense of the basic oneness of humanity, the human solidarity in spite of differences," he interprets the (...) three great philosophical traditions in terms of their respective approaches to the inward and outward aspects of reality. The central meaning or thrust of these traditions is expressed in the titles of the major sections of the book: "Western philosophy and the struggle for the liberation of the outward," "Chinese philosophy and human mindfulness," and "Indian philosophy and explication of inwardness." Western philosophy accomplished primarily a "liberating of the object or outwardness from its entanglement with the subject or inwardness." Chinese philosophy, by trying to build an ethics and philosophy on the emotional rather than the rational nature of man, has struck an even balance between the extremes of inward and outward by establishing clear lines of relatedness between individual men, society, and nature. Indian philosophy has been characterized chiefly by a "reflective inwardness," an overriding concern for the nature of the ätman, the interrelationship between intellect and intuition and the way to ultimate liberation from the round of rebirth and redeath through the immediate, intuitive apprehension of the unity of all things. The final section is dedicated to a general overview of the three major traditions in which the author delineates some of the more obvious and central parallels and distinctions among them. While the book is filled with useful information, novices are sure to be misled and professionals disappointed by the attempts to reduce entire religio-philosophical traditions to a set of neat interpretative labels, such as: Judaism is ethical zeal, Christianity is neighborly love, Buddhism is compassion, Islam is social solidarity, and the Upanishads is divine communion.--J.

Many mammals use scent marks to advertise territory ownership, but only recently have we started to understand the complexity of these scent signals and the types of information that they convey. Whilst attention has generally focused on volatile odorants as the main information molecules in scents, studies of the house mouse have now defined a role for a family of proteins termed major urinary proteins (MUPs) which are, of course, involatile. MUPs bind male signalling volatiles and control their release (...) from scent marks. These proteins are also highly polymorphic and the pattern of polymorphic variants provides a stable ownership signal that communicates genome‐derived information on the individual identity of the scent owner. Here we review the interaction between the chemical basis of mouse scents and the dynamics of their competitive scent marking behaviour, demonstrating how it is possible to provide reliable signals of the competitive ability and identity of individual males.

Open-uterine surgery to repair spina bifida, or ‘fetal surgery of open neural tube defects,’ has generated questions throughout its history—and continues to do so in a variety of contexts. As clinical ethics consultants who worked (Mark J. Bliton) and trained (Virginia L. Bartlett) at Vanderbilt University—where the first successful cases of open-uterine repair of spina bifida were carried out—we lived with these questions for nearly two decades. We worked with clinicians as they were developing and offering the procedure, with researchers (...) in refining and studying the procedure, and with pregnant women and their partners as they considered whether to undergo the procedure. From this experience in the early studies at Vanderbilt, we learned that pregnant women and their partners approach the clinical uncertainty of such a risky procedure with a curious and unique combination of practicality, self-reflection, fear, and overwhelming hope. These early experiences were a major contributing factor to the inclusion of an ethics-focused interview in the informed consent process for the Management of Myelomeningocele Study (MOMS) trial study design.

Three long papers are collected here which constitute Chomsky’s major theoretical work on syntax and semantics subsequent to the "standard theory" of Aspects of the Theory of Syntax. Since 1965, transformational-generative linguists have suggested various changes in "standard theory," centering on the relationship between the syntactic and semantic components in natural language grammars. In these papers Chomsky explains several specific problems that require the extension of standard theory and he criticizes the proposals and arguments of the generative semanticists, attempting (...) to show that many of the specific features of language that are claimed to support the generativist position are as well or better explained by extended standard theory, and emphasizing that most of the generativist’s proposals turn out to be mere "notational variants," evidentially indistinguishable from extended standard theory. Aside from appealing to particular data favoring his "lexicalist" defense of syntactic deep structure, Chomsky makes a Popperean appeal that his position is preferable because it is more constraining and more falsifiable.

Published in 1913 as _La Philosophie Bergsonienne_, this incisive critique of the thought of Henri Bergson was Jacques Maritain's first book. In it he shows himself already to have an authoritative grasp of the thought of St. Thomas Aquinas and an uncanny ability to demonstrate its relevance to alternative philosophical systems such as that of Henri Bergson. Volume 1 in the series _The Collected Works of Jacques Maritain_, this edition faithfully reproduces the 1955 translation published by the Philosophical Library. It (...) would be difficult to overestimate Bergson’s role in extricating French philosophy from the deadening materialism that dominated the Sorbonne. It was that cultural milieu that brought Maritain and his wife Raïssa to the brink of suicide. They drew back for two major reasons. First were the lectures of Henri Bergson at the Collège de France, in which the Maritains found a defense of metaphysics, of the transcendent beyond the material, within which they could find meaning in life. The second reason was their conversion to Catholicism, a move they and many of their contemporaries made after being introduced to Bergson’s work. Soon after his conversion, Jacques Maritain immersed himself in the thought of Thomas Aquinas and was struck by the comparative weaknesses of Bergson. This book is Maritain’s relentless criticism of the philosophy of the man whose lectures had meant so much to him. Its ferocity marks it as a young man’s book, written in part to exorcize the defects of Bergson’s philosophy as they were understood by one now schooled in Thomism. Twenty-five years later, Maritain, while not retracting his criticisms, regretted their intemperance and, as a result, moderated his assessment of Bergson in a long preface to the second edition. In it, we find a philosopher who mastered his craft and a critic of rare perception and refinement. (shrink)

This is a superb introduction to the application of Chomskian linguistics in cognitive psychology and the study of linguistic performance. It is exceptionally clear, accurate, concise, and well-organized; so very well done, in fact, that it can be read by someone who knows nothing about recent linguistics or about its use in psychological experimentation, and yet can delight and profit readers who know a great deal about both subjects. Greene begins by giving a clear and discrete account of the linguistic (...) theory of Syntactic Structures and the later "standard theory" of Aspects of the Theory of Syntax. This historical approach is helpful because the first psycholinguistic applications derived from the first theory: e.g., attempts were made by George Miller, et alia to confirm that the time taken to grasp a sentence depended on the number of optional transformations involved in its generation—a "kernel sentence" with no optional transformations would take less time than its passive or negative transform, and these in turn less than, say, its passive and negative transform. Since there are neither kernel sentences nor the relevant optional transformations in Aspects standard theory, later experimentation has been concerned with confirming the psychological reality of deep, as against surface, structure: e.g., Bever’s attempt to show that, given that a subject who hears an anomalous click while listening to a sentence will psychologically displace the click to a position between major sentence constituents, there is some tendency for the displacement to operate in terms of what the grammar indicates are deep structure divisions rather than surface ones.
