Engaging in environmental stewardship is critical for sustainability. Understanding individual differences and engagement is an important gap in present scholarship and addressing it is necessary to understand individual factors that relate to the types of activities engaged in, motivations and barriers to environmental stewardship. We surveyed 637 Canadian and American adults via Amazon Mechanical Turk, querying a range of demographic, psychological and environmental perceptions factors as well as motivations and barriers to stewardship activities. Respondents were ultimately grouped into Non-Stewards, Home-Oriented (...) Stewards and Community-Oriented Stewards. Few differences were found among these groups. However, Home-Oriented Stewards and Community-Oriented Stewards exhibited very different initial and ongoing motivations to engage in environmental stewardship. Accordingly, we identify stewardship motivations as a potential leverage point and as one of several promising avenues for future research related to enhancing engagement in environmental stewardship for the sustainability of the planet.

Miller, D., G. Nadathur, F. Pfenning and A. Scedrov, Uniform proofs as a foundation for logic programming, Annals of Pure and Applied Logic 51 125–157. A proof-theoretic characterization of logical languages that form suitable bases for Prolog-like programming languages is provided. This characterization is based on the principle that the declarative meaning of a logic program, provided by provability in a logical system, should coincide with its operational meaning, provided by interpreting logical connectives as simple and fixed search instructions. The (...) operational semantics is formalized by the identification of a class of cut-free sequent proofs called uniform proofs. A uniform proof is one that can be found by a goal-directed search that respects the interpretation of the logical connectives as search instructions. The concept of a uniform proof is used to define the notion of an abstract logic programming language, and it is shown that first-order and higher-order Horn clauses with classical provability are examples of such a language. Horn clauses are then generalized to hereditary Harrop formulas and it is shown that first-order and higher-order versions of this new class of formulas are also abstract logic programming languages if the inference rules are those of either intuitionistic or minimal logic. The programming language significance of the various generalizations to first-order Horn clauses is briefly discussed. (shrink)

This article argues that blacks should reject integration on self-protective and solidarity grounds. It distinguishes two aspects of black devaluation: a ‘stigmatization’ aspect that has to do with the fact that blacks are subject to various forms of discrimination, and an aesthetic aspect (‘phenotypic devaluation’) that concerns the aesthetic devaluation of characteristically black phenotypic traits. It identifies four self-worth harms that integration may inflict, and suggests that these may outweigh the benefits of integration. Further, it argues that, while the integrating (...) process may reduce stigmatization, there is less reason to think that it can do the same for phenotypic devaluation. (shrink)

In theory, flawed arguments are not individually sufficient to justify a conclusion, but several may converge to do so. This is an empirical study of how arguers respond to a series of imperfect causal arguments during a serious conversation. People became less critical of the flawed arguments as more of the arguments appeared. The study gives empirical evidence that ordinary arguers permit sufficiency to accumulate during an extended discussion.

This research project substantially extends the reach of serial argument theory from its nearly exclusive application to close relationships, into the workplace. Data were gathered on general motivation to engage in a serial argument, specific goals, several tactics, and three outcome measures. Results indicated causal relations from goals and motivations to tactics, and from tactics to outcomes. A structural equation model was successful in fitting the whole system of variables. Results were generally compatible with those found in relational and classroom (...) settings, and help build the case that serial arguing has certain base characteristics that may not change much when settings are quite substantially different.

The new field of quantitative health risk assessment owes its emergence much more to the 'market pull' of demand from societal decision-making processes than to dramatic advances in our ability to make the desired predictions. This paper discusses problems and opportunities in the current practice of quantitative risk estimation under three broad headings: Basic (Technical) Assessment Methodology, and Methods for Assessing Uncertainty; Conception of the Problem for Analysis, and Ways of Expressing Results; and Defining Appropriate Roles for Expert Analysts in (...) Social Decision Processes. Finally, borrowing from work of McMullin, the paper offers some criteria for judging risk assessment theories other than the generally unavailable 'goodness-of-fit' procedures. (shrink)

In this paper, I investigate the nature and source of judicial reason to conform to law. I argue that a proper account of judicial normativity requires that we treat the fact of law, independent of its substantive moral content, as providing a reason for judges to maintain judicial fidelity. I then offer an explanation of the intrinsic normativity of law, viz., the fact of judicial power, and the reason-giving expectations of subordinates in power relations.

ABSTRACTThere is a growing body of literature describing conceptual frameworks for working with participatory visual methods. Through a global health lens, this paper examines some key themes within these frameworks. We reflect on our experiences of working with with an array of PVM to engage community members in Vietnam, Kenya, the Philippines and South Africa in biomedical research and public health. The participants that we have engaged in these processes live in under-resourced areas with high prevalence of communicable and non-communicable (...) diseases. Our paper describes some of the challenges that we have encountered while using PVM to foster knowledge exchange, build relationships and facilitate change among individuals and families, community members, health workers, biomedical scientists and researchers. We consider multiple ethical situations that have arisen through our work and discuss the ways in which we have navigated and negotiated them. We offer our reflections and learning from facil...

This collection explores the growing interface between Eastern and Western concepts of what it is to be human from analytical psychology, psychoanalytic and Buddhist perspectives. The relationship between these different approaches has been discussed for decades, with each discipline inviting its followers to explore the depths of the psyche and confront the sometimes difficult psychological experiences that can emerge during any in-depth exploration of mental processes. _Self and No-Self_ considers topics discussed at the Self and No-Self conference in Kyoto, Japan (...) in 2006. International experts from practical and theoretical backgrounds compare and contrast Buddhist and psychological traditions, providing a fresh insight on the relationship between the two. Areas covered include: the concept of self Buddhist theory and practice psychotherapeutic theory and practice mysticism and spirituality myth and fairy tale. This book explains how a Buddhist approach can be integrated into the clinical setting and will interest seasoned practitioners and theoreticians from analytical psychology, psychoanalytic and Buddhist backgrounds, as well as novices in these fields.

In an article “Countering a Counter-intuitive Probability” [4], Lynn E. Rose discusses a question in conditional probability, claiming that the following problem posed by Copi [1] is usually incorrectly solved:Remove all cards except aces and kings from a deck, so that only eight cards remain, of which four are aces and four are kings. From this abbreviated deck, deal two cards to a friend. If he looks at his cards and announces that his hand contains an ace, what is the (...) probability that both his cards are aces? If he announces instead that one of his cards is the ace of spades, what is the probability then that both his cards are aces? (shrink)

Climate change has become the most pressing moral and political problem of our time. Ethical theories help us think clearly and more fully about important moral and political issues. And yet, to date, there have been no books that have brought together a broad range of ethical theories to apply them systematically to the problems of climate change. This volume fills that deep need. Two preliminary chapters--an up-to-date synopsis of climate science and an overview of the ethical issues raised by (...) climate change--set the stage. After this, ten leading ethicists in ten separate chapters each present a major ethical theory and discuss the implications of that view for how we decide to respond to a rapidly warming planet. Each chapter first provides a brief exposition of the view before working out what that theory "has to say" about climate change and our response to the problems it poses. Key features: - Up-to-date synopsis of climate science - Clear overviews of a wide range of ethical theories and perspectives by leading experts - Insightful discussions of the implications of these theories and perspectives for our response to climate change - A unique opportunity to assess the relative strengths and weaknesses of various ethical viewpoints.

When Putin became president at the beginning of the 21st century, Russia was in shambles. Putin saw his task to be two fold. First, to recreate the Russian state – that had been seriously weakened by Boris Yeltsin. Second, he set out to reestablish Russia as an important international actor. His approach to dealing with those two tasks was heavily influenced by his approach to dealing with political problems. He is determined, but non ideological. He believes that Russia is unique (...) and that only "Russian" solutions will resolve the country’s problems. Most of all, Putin sees himself as a "problem solver," something that comes from his years in the KGB. And while much remains to be done, he did a lot to solve Russia’s problems. The power of the state has been restored, and Russia is taken far more seriously on the international stage than it was in 2000. What is amazing, given all of the criticism he has received in the West for his "undemocratic" actions, his standings in the polls for the eight years he was in office remained above 70%, something a Western politician can only dream of.

In An Autobiography, R.G. Collingwood offers a strikingly compact reductio ad absurdum of John Cook Wilson's metaphysical realism. Cook Wilson formulates the thesis as the inefficacy of epistemic states to determine the properties of objects of knowledge. He explains realism, according to Collingwood, as the view that 'knowing makes no difference to what is known'. Collingwood objects that any such formulation is 'meaningless'. The problem is that by implication the metaphysical realist is supposed to know that Cook Wilson's principle is (...) true, which requires the realist per impossibile to know what something is like even when its properties are unknown.

El contraste que habitualmente se establece entre el Utilitarismo y la teoría de la virtud queda en entredicho en este ensayo. El Utilitarismo puede encamar cualquier conducta, ya que implica que deberíamos mentir, engañar, robar y aun apropiamos de Aristóteles, si con ello vamos a ocasionar los mejores resultados. En algunas situaciones y en algunos mundos posibles, lo mejor se obtendría centrándonos en los rasgos de carácter. El Cambio Medioambiental Global nos lleva al estudio de los caracteres, puesto que en (...) este caso los mejores resultados se obtienen, generalmente, al disociar nuestro comportamiento del de los demás. Por ello, en este caso y en este mundo, los utilitaristas deberían ser teóricos de la virtud. (shrink)

Marx and Engels argue that capitalism must ultimately destroy itself because it contains an internal contradiction: Capitalism requires wage laborers at first to be in competitive isolation from one another, lest their common interests become transparent and they unite collectively to improve their employment conditions. At a certain later stage of capitalism's historical development, however, competition eventually forces capitalists to bring their workers together in common workplaces , where their shared interests can be immediately perceived and mutual grievances directly communicated. (...) The Communist Manifesto's argument for the inevitable downfall of capitalism is epistemically naïve in several ways, resting as it does on the idea that material interests are perceivable, and that an awareness of common problems translates automatically into a sense of shared interests powerful enough to motivate coordinated action for the sake of achieving economic-political reform.

Meinong's doctrine of the modal moment and the watering-down of extranuclear properties to surrogate nuclear counterparts was offered in response to Russell's problem of the existent round square. To avoid an infinite regress of successively watered-down factualities, Meinong stipulates that the modal moment itself cannot be watered-down. This limits free assumption, since it means that the idea of the existent-cum-modal-moment round square cannot be entertained in thought. It is possible to eliminate the modal moment and watering-down from Meinongian semantics in (...) favor of a strict enforcement of the distinction between nuclear and extranuclear properties. This provides a simpler, more economical Meinongian object theory, and regains unrestricted free assumption. (shrink)

This chapter contains sections titled: Creative Inner Space O True Apothecary! A Votary to Fond Desire Philosophers Gaining Altitude Insight and Delusion Life, Liberty, and the Pursuit of Cannabis.

As the American President Jimmy Carter put it, “Penalties for possession of a drug should not be more damaging to an individual than the use of the drug itself”. I infer that cannabis prohibition is morally unjustified.

The thesis that entities exist in, at, or in relation to logically possible worlds is criticized. The suggestion that actually nonexistent fictional characters might nevertheless exist in nonactual merely logically possible worlds runs afoul of the most general transworld identity requirements. An influential philosophical argument for the concept of world-relativized existence is examined in Alvin Plantinga’s formal development and explanation of modal semantic relations. Despite proposing an attractive unified semantics of alethic modality, Plantinga’s argument is rejected on formal grounds as (...) supporting materially false actual existence assertions in the case of actually nonexistent objects in the framework of Plantinga’s own underlying classical predicate-quantificational logic.

As a contribution to the critical appreciation of a central thesis in Russell’s philosophical logic, I consider the Third Man objection to Platonic realism in the philosophy of mathematics, and argue that the Third Man infinite regress, for those who accept its assumptions, provides a worthy substitute for Whitehead and Russell’s Axiom of Infinity in positing a denumerably infinite set or series onto which other sets, series, and formal operations in the foundations of mathematics can be mapped.
