Painters are the experts in colour phenomenology. Their business is to use colour to affect our feelings. Psychophysicists are expert in making experimental inferences from behavioural responses to the functional mechanisms of perception. The varying aims of these two groups of people mean that much that is of interest to the one is of little concern to the other. However, in recent times several prominent psychophysicists, such as Floyd Ratliff , Jack Werner and Dorothea Jameson , have thrown much (...) light on painterly practice. Following their lead, I would like to sketch some of the mechanisms that are responsible for many of the features of colour appearance important to the work of visual artists. I will begin with some phenomena that can be accounted for by mechanisms that are reasonably well understood, and then move to phenomena whose underlying basis is less well established. I will conclude with a suggestive experiment and, true to my calling as a philosopher, a piece of downright speculation. (shrink)

Do the rich descriptions and narrative shapings of literature provide a valuable resource for readers, writers, philosophers, and everyday people to imagine and confront the ultimate questions of life? Do the human activities of storytelling and complex moral decision-making have a deep connection? What are the moral responsibilities of the artist, critic, and reader? What can religious perspectives—from Catholic to Protestant to Mormon—contribute to literary criticism? Thirty well known contributors reflect on these questions, including iterary theorists Marshall Gregory, James Phelan, (...) and Wayne Booth; philosophers Martha Nussbaum, Richard Hart, and Nina Rosenstand; and authors John Updike, Charles Johnson, Flannery O'Connor, and Bernard Malamud. Divided into four sections, with introductory matter and questions for discussion, this accessible anthology represents the most crucial work today exploring the interdisciplinary connections between literature, religion and philosophy.

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need (...) to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

Mastery imagery (i.e., images of being in control and coping in difficult situations) is used to regulate anxiety. The ability to image this content is associated with trait confidence and anxiety, but research examining mastery imagery ability's association with confidence and anxiety in response to a stressful event is scant. The present study examined whether trait mastery imagery ability mediated the relationship between confidence and anxiety, and the subsequent associations on performance in response to an acute psychological stress. Participants (N= (...) 130; 55% male;Mage= 19.94 years;SD= 1.07 years) completed assessments of mastery imagery ability and engaged in a standardized acute psychological stress task. Immediately prior to the task, confidence, cognitive and somatic anxiety intensity, and interpretation of anxiety symptoms regarding the task were assessed. Path analyses supported a model whereby mastery imagery ability mediated the relationship between confidence and cognitive and somatic anxiety interpretation. Greater mastery imagery ability and confidence were both directly associated with better performance on the stress task. Mastery imagery ability may help individuals experience more facilitative anxiety and perform better during stressful tasks. Improving mastery imagery ability by enhancing self-confidence may help individuals successfully cope with anxiety elicited during stressful situations. (shrink)

Responds to S. C. Yanchar and K. B. Kristensen's comments on L. T. Hoshmand and J. Martin's proposal for a naturalistic epistemological approach. Further clarification of the proposal is provided and implications for the development of a theory of method and issues of communal evaluation and intelligibility are discussed. 2012 APA, all rights reserved).

One dark and rainy night, Yuso sexually assaults and tortures Zelan. In escaping from the scene of his crime, he falls heavily and becomes an impotent paraplegic. Instead of treating his fate as divine retribution for his wicked acts, Yuso sees it as sheer bad luck. He shows no remorse for what he has done, and vainly hopes that he will recover his powers, which he now treats as involuntarily hoarded resources to be used on less rainy days. In the (...) presence of others, he pretends that he has turned over a new leaf. He asks for religious and educational books, hoping to make up for his poor education and deprived social background. But he immediately discards them when he is alone in favor of the pornographic magazines which he has bribed a nurse to smuggle in for him. His deception and various obscene acts committed in the hospital are exposed; by the time he comes up for trial, everyone knows that he is still a lustful, sadistic, and unrepentant man. Most retributivists have a sufficient justification for punishing Yuso independently of the social consequences of his punishment. Two features of the case might cause some difficulties. First, Yuso has already experienced considerable suffering and deprivation both before and after his crime, and retributivists might disagree about the relevance of the suffering to his punishment. Secondly, Yuso is unrepentant, and it is unlikely that punishment will change him. This might, as we shall see, create a problem for those who think that the justifying aim of punishment is the moral reform of the offender. (shrink)

In Defense of Utilitarianism, C.L. Sheng provides a more intensive study of the Unified Utilitarian Theory , which he proposed in his previous work A New Approach to Utilitarianism . Sheng defends utilitarianism, particularly UUT, against the objections and attacks raised by nonutilitarians, showing it to be a viable ethical theory.

Adaptive management is commonly identified as a way to address situations where ecological and social uncertainty exists. Two discourses are common: a focus on experimentation, and a focus on collaboration. The roles of experimental and collaborative adaptive management in contemporary practice are reviewed to identify tools for bridging the discourses. Examples include broadening the scope of contributions during the buy-in and goal-setting stages, using conceptual models and decision support tools to include stakeholders in model development, experimentation using indicators of concern (...) to stakeholders, an experimental focus that reflects the level of statistical confidence required by management, and the engagement of stakeholders in data interpretation so that those affected by management outcomes can learn and adapt accordingly. In this context, a framework of questions that managers can use to reflect on both ecological and social uncertainties as they relate to individual management contexts is proposed. (shrink)

A number of recent studies have documented rapid changes in behavioural sensory acuity induced by aversive learning in the olfactory and auditory modalities. The effect of aversive learning on the discrimination of low-level features in the visual system of humans remains unclear. Here, we used a psychophysical staircase procedure to estimate discrimination thresholds for oriented grating stimuli, before and after differential aversive learning. We discovered that when a target grating orientation was conditioned with an aversive loud noise, it subsequently led (...) to an improvement of discrimination acuity in nearly all subjects. However, no such change was observed in a control group conditioned to an orientation shifted by ±90° from the target. Our findings cannot be explained by contextual learning or sensitisation factors. The results converge with those reported in the olfactory modality and provide further evidence that early sensory systems can be rapidly modified by recently experienced reinforcement histories.

The papers in this volume focus on two central issues in the philosophy of law, the relationship between law and morality, and crime and punishment. In the essay that gives the title to this volume, it is argued that, although in many legal systems there are in fact significant connections between law and morality, these connections are not conceptually or logically necessary. They depend on various social practices. Ronald Dworkin's famous attempt to undermine the legal positivist's separation of law from (...) morality is rejected, and it is argued that Dworkin's own positive theory of law may indeed be quite compatible with certain versions of legal positivism. Other essays explore the notion of a wicked legal system, the rule of law, and various perspectives on the nature of law. The essays on crime and punishment discuss the theory and practice of punishment. They extend the work done in the author's earlier book, "Crime, Guilt and Punishment". They reject a purely retributive justification of punishment, in spite of the increasing sophistication in its recent formulations. (shrink)
