Presented in this study is an analysis of the electronic properties of doped diamond calculated using the Vienna ab initio simulation package, employing density functional theory within the generalized-gradient approximation. The dopants studied here have been inserted substitutionally into a 64-atom diamond supercell and include the single-electron acceptors boron and aluminium, the single-electron donors nitrogen and phosphorus and the double-electron donors oxygen and sulphur. Co-doping of diamond with sulphur and boron has also been briefly examined. The doped supercells have been (...) relaxed, followed by calculation of electronic properties from the electronic density of states such as the indirect bandgap E g , the valence bandwidth and an examination of the acceptor and donor states in the bandgap. It is anticipated that this study will provide a useful comparison of the third- and fourth-row donors and acceptors in diamond. (shrink)

In this study an analysis is presented of the bonding and structural properties of dehydrogenated and hydrogenated doped cylindrical diamond nanowires calculated using the Vienna Ab Initio Simulation Package, employing density functional theory within the generalized-gradient approximation. The dopants studied here have been inserted substitutionally along the axis of an infinite one-dimensional diamond nanowire and include the single-electron acceptor boron and the single-electron donor nitrogen. The doped nanowires have then been re-relaxed, and properties compared with the undoped structures. The structural (...) properties of relaxed nanowires considered here include an examination bonding via the electron charge density, with the aim of providing a better understanding of the effects of dopants on the stability of diamond nanostructures and nanodevices.

In this study an analysis is presented of the bonding and structural properties of dehydrogenated and hydrogenated doped cylindrical diamond nanowires calculated using the Vienna Ab Initio Simulation Package, employing density functional theory within the generalized-gradient approximation. The dopants studied here have been inserted substitutionally, equidistant along the axis of an infinite diamond nanowire. These dopants include aluminium, phosphorus, oxygen and sulphur. The doped nanowires have then been re-relaxed, and properties compared with previously calculated results for undoped, boron-doped and nitrogen-doped (...) structures. Structural properties of relaxed nanowires considered here include an examination bonding via the electron charge density, with the aim of providing a better understanding of the effects of dopants on the stability of diamond nanostructures and nanodevices.

A typical guiding principle of an account of truth is: “truth is objective,” or, to be clear, judging whether an assertion is true or false depends upon how things are in the world rather than how someone or some community believes it to be. Accordingly, whenever a claim is objectively true, its truth conditions ought not depend upon the context in which it is uttered or the utterer making the claim. Part of our ongoing empirical studies surveying people’s responses to (...) questions about truth involved prompts on objectivity. Our studies suggest the following: overall, individuals tend to endorse claims that are consistent with the objectivity of truth; not all conceptions of objectivity are equal, even people who endorse the objectivity of truth sometimes assent to one form of truth’s objectivity over other forms; philosophers and non-philosophers both endorse the objectivity of truth, but the apparent commitment of philosophers is stronger.

Many of Tarski’s better known papers are either about or include lengthy discussions of how to properly define various concepts: truth, logical consequence, semantic concepts, or definability. In general, these papers identify two primary conditions for successful definitions: formal correctness and material adequacy. Material adequacy requires that the concept expressed by the formal definition capture the intuitive content of truth. Our primary interest in this paper is to better understand Tarski’s thinking about material adequacy, and whether components of his view (...) developed over time. More precisely, we are concerned with how Tarski’s understanding of the content of the common-sense, every-day usage of truth may have developed over time. We distinguish this concern from the character of the extensional criterion of adequacy Tarski proposes: that a materially adequate definition must entail all instances of Convention T. We will develop our reading of Tarski as follows: first, we will review the “Polemical Remarks,” focusing primarily on §§14 and 17, and Tarski’s references to Naess’ empirical research. Next, we will provide a summary and discussion of Naess’ work, especially his findings with respect to Tarski’s definition of truth and his research that suggests there is no single common or everyday concept of truth. Third, we will consider several possible objections to our interpretation of the Tarski–Naess dialectic. We will conclude that Tarski’s conception of material adequacy developed over time, potentially because of what he had learned through his interactions with Naess. (shrink)

Reviews the book, Constructing the self, constructing America: A cultural history of psychotherapy by Phillip Cushman . Phillip Cushman's 1995 Constructing the self, constructing America: A cultural history of psychotherapy provides both a far-reaching critique of psychoanalysis in America and an alternative theoretical approach founded on the notion of the self as sociohistorically configured and moral. With the proliferation and sometime redundancy of critiques of the mainstream, it would not be unfair to ask what Cushman's critical analysis effects beyond what (...) has already found its way into print. To begin with, his contribution is distinguished by its object. Whereas most critiques are aimed at theories and practices as institutionalized in the academy, Cushman takes as his primary target those which have dominated the professional practice of psychotherapy in America. 2012 APA, all rights reserved).

PurposeThe purpose of this paper is to present a four component model of ethical behavior (PRIMES) that integrates literature in moral psychology, computing ethics, and virtue ethics as informed by research on moral exemplars in computing. This is part 1 of a two‐part contribution.Design/methodology/approachThis psychologically based and philosophically informed model argues that moral action is: grounded in relatively stable PeRsonality characteristics (PR); guided by integration of morality into the self‐system; shaped by the context of the surrounding moral ecology; and facilitated (...) by morally relevant skills and knowledge (S).FindingsThe model seeks to explain the daily successful (and unsuccessful) performance of moral action by computing professionals and to provide groundwork for a pedagogy that emphasizes ethically effective performance.Practical implicationsThe model has significant implications for how ethical action might be taught to computer professionals and other design professionals. It also makes recommendations about what is needed to measure to construct a complete picture of sustained ethical action in a profession.Originality/valueMost accepted models of ethical behavior are unidimensional, emphasizing either principled reasoning or a simplistic model of integrity/character. This model brings together a variety of disparate literatures in the light of its emphasis on sustained moral action in the profession. It thereby provides researchers and educators with a picture of what is needed to construct a complete understanding of moral action in the profession. (shrink)

The interpretation given by Craik and Lockhart of the findings by Hyde and Jenkins involving supposed depth of incidental-task processing on subsequent word recall is brought into question by the tenets of logical learning theory. It is shown that Craik and Lockhart overlooked the possible role of oppositionality in this research. An alternative explanation relying on an oppositional context and predication is offered. Two experiments present evidence supporting the hypothesis that oppositionality in an incidental task facilitates subsequent word recall . (...) In both experiments, the importance of taking a subject's meaningful understanding of the task instruction into consideration is highlighted. The discussion contrasts Boolean "binary" disjunction with the logic of oppositionality. It is shown how oppositionality allows us to conceptualize a testable theory of human agency. (shrink)

The integration of technology in care is core business in nursing and this role requires that we must understand and use technology informed by evidence that goes much deeper and broader than actions and behaviours. We need to delve more deeply into its complexity because there is nothing minor or insignificant about technology as a major influence in healthcare outcomes and experiences. Evidence is needed that addresses technology and nursing from perspectives that examine the effects of technology, especially related to (...) increasing demands for efficiency, the relationship of technology to nursing and caring, and a range of philosophical questions associated with empowering people in their healthcare choices. Specifically, there is a need to confront in practice the ways technique influences care. Technique is the creation of a kind of thinking that is necessary for contemporary healthcare technology to develop and be applied in an efficient and rational manner. Technique is not an entity or specific thing, but rather a way of thinking that seeks to shape and organize nursing activity, and manage efficiently individual difference(s) in care. It emphasizes predetermined causal relationships, conformity, and sameness of product, process, and thought. In response is needed a radical vision of nursing that attempts in a real sense to ensure we meet the needs of individuals and their community. Activism and advocacy are needed, and a willingness to create a certain detachment from the imperatives that technique demands. It is argued that our responsibility as nurses is to respond in practice to the errors, advantages, difficulties, and temptations of technology for the benefit of those who most need our assistance and care.

The liar paradox is widely conceived as a problem for logic and semantics. On the basis of empirical studies presented here, we suggest that there is an underappreciated psychological dimension to the liar paradox and related problems, conceived as a problem for human thinkers. Specific findings suggest that how one interprets the liar sentence and similar paradoxes can vary in relation to one’s capacity for logical and reflective thought, acceptance of certain logical principles, and degree of philosophical training, but also (...) as a function of factors such as religious belief, gender, and whether the problem is treated as theoretical or practical. Though preliminary, these findings suggest that one reason the liar paradox resists a final resolution is that it engages both aspects described by so-called dual process accounts of human cognition.

The core of J.G. Herder's philosophy of nationalism lies in the conviction that human creativity must be embedded in the particular culture of a communal language. While he acknowledged that this cultural particular must be integrated into a more universal humanity, he insisted that each culture should preserve its incommensurable distinctiveness. He also called for a new method of enquiry regarding history, one that demands empathetic sensitivity toward the uniquely individual while realizing that there are few gains without losses. F.M. (...) Barnard demonstrates that Herder, despite his innovative work on the idea of nationality, was fully aware of the dangers of ethnic fanaticism, but also of the hazards of what is now known as globalization, recognizing that these must be tempered by a sense of universal humanity. Barnard shows that Herder anticipated modern theories of the dynamics of cultures and traditions through the problematic interplay of persistence and change and that his speculations on cultural and political pluralism, on language as a democratic bond, and on the possible fusion of communitarian and liberal dimensions of public life remain relevant to contemporary debates.

The time has come to consider whether experimental philosophy’s (“x-phi”) early arguments, debates, and conceptual frameworks, that may have worn well in its early days, fit with the diverse range of projects undertaken by experimental philosophers. Our aim is to propose a novel taxonomy for x-phi that identifies four paths from empirical findings to philosophical consequences, which we call the “fourfold route.” We show how this taxonomy can be fruitfully applied even at what one might have taken to be the (...) furthest edges of possible applications of x-phi in metaphysics and formal philosophy. Ultimately, the fourfold route helps us understand a different kind of empirical fact: the development of x-phi itself. (shrink)

Ontological Naturalism holds that our fundamental ontology contains only those generally natural objects, properties, and relations required by our best scientific theory. Logical principles are thought of as being normative of correct inference and as involving necessary truths and relations. Necessary relations are stronger than the relations described by science; norms are traditionally thought to be separate from the descriptive project of science. Yet, ontological theories, including ontological naturalism, employ logic freely without offering an account of logical normativity and necessity. (...) It appears that logical properties and relations are prima facie non-natural. If so, then ontological naturalism paradoxically presupposes the presence of non-natural properties and relations as a part of the ultimate fundamental ontology. I explore this tension between logic and ontology as a means to clarifying the standards of acceptability for ontological theories generally and as a means to clarifying the character of logical discourse. I conclude that all proposed ontological theories must provide a substantive account of logic which respects its intrinsic modal and normative character as a minimal test of meta-ontological acceptability.

Physicians often appear more troubled by moral dilemmas than would seem justified given the present social and professional consensus on many of the questions involved. Their discomfort arises not only at ethical, technical, and behavioral levels (the most commonly identified sources of difficulty), but also at an existential level, that is, as the manifestation of conflicts rooted in the processes and conditions of our coming-to-be as persons. Analysis of this level of physicians' moral difficulties requires renewed attention to the physician (...) as a person, and suggests new perspectives on the interpersonal environment of medical practice.

Johann Gottfried Herder (1744-1803) has been called the German Rousseau. Yet while Rousseau is recognized as a political thinker, Herder is not. This book explores each thinker's ideas--on nature and culture, selfhood and mutuality, paternalism, freedom, and autonomy--and compares their conceptions of legitimate statehood. Arguing that the crux of political legitimacy for both men was the possibility of "extended selfhood," Barnard shows that Herder, like Rousseau, profoundly altered human self-understandings, thus influencing modes of justifying political allegiance.

ABSTRACTIn the first notebook published in Überlegungen II-VI, which covers the years 1931 and 1932, Martin Heidegger uses a conception of power that is different to that found in his later work. Rather than power being the expression of the will to will and source of ruin for humanity, he says that humanity can only be saved from ruin if it can pave the way for an “empowerment of being”. This article will show that this early understanding of power is (...) related to Heidegger’s conception of freedom as the essence of truth, developing his thinking on this topic from the period of 1927–1930. It will show that the terms “empowerment of being” and “letting be” are akin, and that Heidegger uses the former to distance his thinking from potential misinterpretations of the essay “On the Essence of Truth”.

This paper empirically re(dis)covers a moment of conjuncture within Leicester when an opportunity opened up through multicultural/anti-racist education for schools and colleges to develop their ‘multicultural capital’. It does this through the thematic analysis of the key proximate document Report of the Working Party on Multicultural Education as well as drawing on interview data provided by two important agents who helped to implement Leicester’s/Leicestershire’s moment of multicultural education. This moment generated a symbolic, ideational, and conceptual shift within Leicester’s education provision (...) toward a more culturally inclusive position that began to recognise the cultural capital of non-white students. However, this moment was to be lost in the ‘neoliberal epoch’. It is argued in this paper that neoliberal education policy/practice has become an enabling mechanism for renascent colonial ideology. By re(dis)covering this vision for the official recognition of non-white cultural capital, this paper demonstrates the possibilities for alternative directions within Leicester’s schools and colleges that can challenge neoliberal and colonial conceptions of education. It suggests that there are still spaces and structures that can be re(dis)covered in order for this vision to be enabled. (shrink)

The ability to (re)classify populations is a key component of state power, but not all new state classifications actually succeed in changing how people are categorized and governed. This article examines the French state’s partly unsuccessful project in 2005 to use a new classification—“psychic handicap”—to ensure that people with severe mental disorders received services and benefits from separate agencies based on a designation of being both “mentally ill” and “disabled.” Previous research has identified how new classifications can be impeded by (...) cultural and cognitive barriers to their adoption and struggles between professionals or administrators over their implementation. Drawing on 186 interviews, archival sources, and 13 months of observations across different French bureaucracies, I expand on this literature in two ways. First, I use the case of psychic handicap to argue that a new classification can also fail to achieve its intended effect when it constitutes a bureaucratically split personality—a combination of classifications that imply that individuals belong to two, mutually exclusive kinds of people. I show how psychic handicap embodied contradictory expectations about the behavior, characteristics, and institutional trajectory of people with mental disorders. Second, I identify how bureaucrats resolved these contradictions through mechanisms of refractory looping, outsourcing expertise, and classification by default, which in this case led to the reclassification of this population as simply “mentally ill.” This framework calls attention to how practical inconsistencies can limit the impact of new classifications, even absent overt resistance to their elaboration or implementation.

Collingwood's faith in the historian's intuitive capacity for discerning the meaning of past actions by re-enactment" is too unqualified. However, his thesis that through actions alone can reasons and inner meanings be discovered is true. This assumes that actions can be traced to recognizable agents and that these agents are able to acknowledge their reasons. The relation between knowing and doing and between knowing and understanding is a form of causality not inconsistent with teleological reasoning. Characteristic of human action are (...) the constitutive nature of causality, the delimiting effect of rationality on human autonomy, and the role of purpose as a mediating link between intention and outcome. Despite the fact that emphasis on impersonal actions and interactions seriously calls into question Collingwood's theory of understanding, any radical revision of this theory proves no less problematical.

[opening paragraph]: A colleague of mine at Southern Methodist University recently shared a story with me. Several years ago my colleague was hired as the chairman of a new department of religious studies at a major research university. It was his job to interview candidates to fill several positions in the department. The Dean was adamant that, in order to ensure scholarly objectivity, anyone hired to teach religious studies should not have deeply held religious beliefs; however my colleague went to (...) the Dean in hopes of convincing him otherwise. `You can certainly say whatever you want to', the Dean responded, `but you should know in advance that my mind is already made up.' My colleague did not share with me his whole argument, but he did mention what must have given even that hard-nosed Dean a moment's pause: `It seems that, in this department', my colleague pointedly remarked, `it would be fine to hire an historian who is an expert on Thomas Aquinas; but, according to your rules, we couldn't hire Thomas Aquinas himself.'.

Henri Bergson created a rich and detailed theory of consciousness beginning with the publication of Time and Free Will in 1889 and continuing through the publication of The Two Sources of Morality and Religion in 1932. His theory had much in common with William James’s views in that both emphasized consciousness as a continuous process. James's famous ‘stream of consciousness’ is strikingly similar to Bergson's early notion of duration (duree), even if Bergson more strongly emphasized the temporal qualities of consciousness. (...) Bergson later modified his understanding of consciousness, creating a metaphysical vision that he hoped might not only overcome determinism and materialism, but also offer a sophisticated way to understand parapsychological phenomena such as telepathy and clairvoyance (topics of concern to many major theorists of the time). During his life, Bergson’s ideas were widely celebrated in the United States and in Europe. (shrink)

This book foregrounds postcolonial theory as a lens through which to explore the concept of 'global heritage' and argues that the meso-level spaces of institutional ethos and cultural pedagogy must take an active role in the pursuit of cultural equality. Through interviews and accounts of observational, eampirical data, chapters draw attention to how the cultural capital of Global Majority students is institutionally positioned as a racialised and inferior cultural capital that is constantly required to 'prove itself' in the Western school. (...) Ultimately, the book contributes to international discussion on decolonising education and the spaces within in order to enact change, further the field, and more precisely to recognise the importance of global heritage as vital to a transformative understanding of the West's cultural identity within a globalised world. This book will appeal to scholars, researchers, and post-graduate researchers in the fields of multicultural education, school leadership, management and administration, and education policy and politics more broadly. Those interested in social justice, ideas of cultural and racial equality, and the sociology of education more broadly will also benefit from the volume. (shrink)

The texts collected in this volume, which was originally published in 1969, contain Herder's most original and stimulating ideas on politics, history and language. They had for the most part not been previously available in English. In his introduction, Professor Barnard analyses the basic premises of Herder's political thought against the background of the Enlightenment. He examines Herder's concepts of language, community and culture, his theory of historical interaction, and his approach to the problem of change and progress. Finally, (...) he provides a brief comparative analysis of traditionalist thought following the French Revolution, showing how substantive writers like Burke differed from Herder despite the close similarity of political vocabulary.

: In 1998, 39 pharmaceutical manufacturers sued the government of South Africa to prevent the implementation of a law designed to facilitate access to AIDS drugs at low cost. The companies accused South Africa, the country with the largest population of individuals living with HIV/AIDS in the world, of circumventing patent protections guaranteed by intellectual property rules that were included in the latest round of world trade agreements. The pharmaceutical companies dropped their lawsuit in the spring of 2001 after an (...) avalanche of negative publicity. Yet, despite the government's victory, AIDS drugs remain very expensive in South Africa, and the government still refuses to provide antiretroviral therapy to adults. These events have shone a spotlight, not only on the possibilities for coordinated political activism in the era of instant global communications, but also on the tangled social, economic, and political dimensions of AIDS treatment in poor countries.

This Philosophical Companion collects sixteen papers organized by theme and sequence to follow the broad outline of a generic course in the logic of first-order quantification. The papers range from 5-34 pages in length and vary widely in degree of technical difficulty. Most of the papers have previously appeared, and only one – the editor’s contribution—was written specifically for the volume. With the publication of this excellent little book, Hughes therefore provides a useful template for the instructor who wants to (...) instill a deeper appreciation of the philosophical side of the discipline in his or her students and fills the gap created when older anthologies such as Copi and Gould’s Readings on Logic or Strawson’s Philosophical Logic went out of print. While similar to each of these classic volumes, the present text is unique in its focus on first order logic; Copi and Gould emphasized topics better suited to an introductory level course while the Strawson text covers topics which are on the one hand slightly more advanced and on the other marked by their historical context.

In a qualitative empirical research project on youth worship, we discovered that 'being together' is primary quality of youth worship. This primary quality consists of at least four aspects. Firstly, community is celebrated through physical presence. More specifically, the physical presence of siblings plays an important part in the participation of youth in worship. Secondly, an empathetic and emotional aspect is essential for adolescents. 'Being together' in youth worship means being together in unity and trust and in equality, as kindred (...) spirits. Thirdly, 'being together' in youth worship yields possibilities to cross social and ecclesiological boundaries. Fourthly, there is a theological aspect in 'being together' that could be described as 'sharing faith and being in God's presence'. (shrink)

This introduction to the basic ideas of structural proof theory contains a thorough discussion and comparison of various types of formalization of first-order logic. Examples are given of several areas of application, namely: the metamathematics of pure first-order logic (intuitionistic as well as classical); the theory of logic programming; category theory; modal logic; linear logic; first-order arithmetic and second-order logic. In each case the aim is to illustrate the methods in relatively simple situations and then apply them elsewhere in much (...) more complex settings. There are numerous exercises throughout the text. In general, the only prerequisite is a standard course in first-order logic, making the book ideal for graduate students and beginning researchers in mathematical logic, theoretical computer science and artificial intelligence. For the new edition, many sections have been rewritten to improve clarity, new sections have been added on cut elimination, and solutions to selected exercises have been included. (shrink)

Open theists argue that God's relationship to time, as conceived in classical theism, is erroneous. They explain that it is contradictory for an atemporal being to act in a temporal universe, including experiencing its temporal successions. Contrary to the atemporalists, redemptive history has shown that God interacts with humans in time. This relational nature of God nullifies the classical notion of God as timelessly eternal. Therefore, it lacks a philosophical and theological basis. Because God is in time, He does not (...) know all future contingencies and, therefore, changes. This study examines open theism's appropriation of the A and B theories of time to the divine-human relationship. The study argues that divine temporality does not solve the tension of divine-human relationships, especially in relation to the future. Further, historical divine temporality does not negate the fact of divine atemporality. It mainly stems from God's choice to create temporal creatures and His relationship with them. Furthermore, if it is not logically and metaphysically contradictory for an omnipresent being to act in space, then it follows that an atemporal being can act in time. Whether time is understood from the metric or psychological point of view, it does not transcend God, and therefore, the limitation it places on human creatures with respect to the future does not apply to God. Lastly, although a few philosophers reject the notion of eternity as timelessly eternal, the doctrine has a philosophical and theological basis in the Scripture. (shrink)
