In lieu of an abstract, here is a brief excerpt of the content:The Power of PersuasionG. Bennett HumphreyA long white coat, the title of doctor, a practiced professional persona and an appointment to the staff of a prestigious university medical center allows the physician to be a persuader of clinical decisions affecting patient management. When this power of persuasion is used to encourage patient compliance with a therapeutic regimen that might be curative for a fatal disease, there is justification (...) for trying to influence the patient to make choices resulting in a positive outcome. But when a physician is asking permission to enter the patient into a research protocol where the primary goal of the study is the hope of advancing knowledge, then much thought needs to be given to the potential abuse of this power of persuasion.In the 1960s, I found myself having to think about recruiting children into research protocols. I had just finished two years of residency in internal medicine and wanted to pursue a career in academic medicine. My primary interest was in laboratory research. To strengthen my training in research, I had competed for a position as clinical fellow in a western university. The fellowship program was designed to expose young physicians to both clinical and laboratory research. The first year was spent on one of the clinical research wards and the second year in a research laboratory. The program was open to residents from surgery, medicine and pediatrics but because there was a shortage of pediatricians in the program, I was required to work on the children’s leukemia ward for one year.The learning curve was steep during the first few months. Naturally, the faculty in pediatrics and the medical literature gave me a technical education in the use of protocols for therapeutic treatment of leukemia. For example, the first protocol used was designated as Phase III, and the goal was to try to cure the patient. A remission could be achieved in over 90 percent of children but the disease recurred. The median duration of these remissions in the mid–1960s was one year. A relapse was followed by progressive disease and death in a matter of weeks, but a new drug of unknown efficacy could be administered. This was a Phase II protocol, and while there was a chance of prolonging life for a month or so, the primary goal was the identification of drugs anti–leukemic activity.The pediatric leukemia ward experience for me as a fellow was unusual. There was more to learn than the treatment of leukemia. To my surprise, the children and their mothers gave me insight into the care of pediatric patients. Each month, the patients were admitted for five days of intravenous chemotherapy. The first day was traumatic with venipunctures, bone marrow aspirations and the establishment of an IV for the daily infusion of drugs. The remaining four days were for social rounds: listening to the children who liked to talk; talking with the ones who liked to listen; putting puzzles together with some toddlers; responding to a request to listen to the heart of a much loved teddy bear; exchanging jokes and riddles; stories about school, the family dog, or a favorite friend; enjoying the banter of the adolescents; and not invading the privacy of a few who didn’t like me, the ward or the therapy. These children were sharing their childhood with me and it took couple of months for me to recognize I was bonding with these little patients. I observed and listened to the mothers caring for their children and stood in awe of the resources that they brought to bear on having children with a fatal disease. A feeling of mutual respect and trust developed between these mothers and me. For an internist, these experiences were profound and very different from my experience treating adults.A professor, an internationally known researcher in the field of leukemia, was in charge of the ward. Formal rounds were conducted on Tuesday mornings when the result of the bone marrow aspirates and the toxicity of the chemotherapy were reviewed. The day–to–day responsibility for [End Page 101] treatment and informing the mothers on the remission status on Mondays was my responsibility... (shrink)

We show how mereotopological notions can be expressed by extending intuitionistic propositional logic with propositional quantification and a strong modal operator. We first prove completeness for the logics wrt Kripke models; then we trace the correspondence between Kripke models and topological spaces that have been enhanced with an explicit notion of expressible region. We show how some qualitative spatial notions can be expressed in topological terms. We use the semantical and topological results in order to show how in some extensions (...) of the logics it is possible to express connectedness, non-emptiness and a set of jointly exhaustive, pairwise disjoint, binary relations that play a significant role in qualitative spatial reasoning.

To the extent that Geary's theory concerning biologically primary and secondary behaviors depends on factor analytic methods and findings, it is woefully weak. Factors have been mistakenly called primary mental abilities, but the adjective “primary” represents reification of a mathematical dimension defined by correlations. Fleshing out a factor beyond its mathematical properties requires much additional quantitative experimental and correlational research that goes far beyond mere factoring.

In this paper I consider whether traditional behaviors of animals, like traditions of humans, are transmitted by imitation learning. Review of the literature on problem solving by captive primates, and detailed consideration of two widely cited instances of purported learning by imitation and of culture in free-living primates (sweet-potato washing by Japanese macaques and termite fishing by chimpanzees), suggests that nonhuman primates do not learn to solve problems by imitation. It may, therefore, be misleading to treat animal traditions and human (...) culture as homologous (rather than analogous) and to refer to animal traditions as cultural. (shrink)

The McCollough effect, an orientation-contingent color aftereffect, has been known for over 30 years and, like other aftereffects, has been taken as a means of probing the brain's operations psychophysically. In this paper, we review psychophysical, neuropsychological, and neuroimaging studies of the McCollough effect. Much of the evidence suggests that the McCollough effect depends on neural mechanisms that are located early in the cortical visual pathways, probably in V1. We also review evidence showing that the aftereffect can be induced without (...) conscious perception of the induction patterns. Based on these two lines of evidence, it is argued that our conscious visual experience of the world arises in the cortical visual system beyond V1. (shrink)

Scientific knowledge and technological expertise continue to evolve rapidly. Such innovation gives rise to new benefits as well as risks, at an ever-increasing pace. Within this context, regulatory regimes must function in order to address policymakers’ objectives. Innovation, though, can challenge the functioning and effectiveness of regulatory regimes. Questions over fit, effectiveness, and capacity of these regimes to ensure the safe entry of such technologies, and their products, onto the market will be asked in parallel to their development. With this (...) in mind, this article examines the strengths and weaknesses of current regulatory frameworks, including those designed for biotechnology, cosmetics, novel organisms, and foods, in order to inform and help shape Australia’s regulatory landscape around innovation. By focusing on Australia, the article illustrates the need to assess future changes to regulatory frameworks using a careful balancing of key factors. These include, for example, horizon scanning and monitoring, availability of appropriate data, existing health, safety, environmental, ethical, and social risks and impacts, and regulatory capacity. The article argues that rather than using one of these factors in isolation, a careful assessment of where each factor stands can lead regulators to an approach that properly manages the potential risks of emerging technologies.

This paper examines an issue that is becoming increasingly relevant as the pressures of a warming planet, changing climate and changing ecosystems ramp up. The broad context for the paper is the intragenerational, intergenerational, and interspecies equity implications of changing the climate and the value orientations of adapting to such change. In addition, the need to stabilize the planetary climate by urgent mitigation of change factors is a foundational ethical assumption. In order to avoid further animal and plant extinctions, or (...) at the very least, their increased vulnerability to becoming rare and endangered; the systematic assisted colonization of “at risk” species is being seriously considered by scientists and managers of biodiversity. The more practical aspects of assisted colonization have been covered in the conservation biology literature; however, the ethical implications of such actions have not been extensively examined. Our discussion of the value issues, using a novel case study approach, will rectify the limited ethical analysis of the issue of assisted colonization of species in the face of climate change pressures. Beyond sustainability ethics, both animal and environmental ethical approaches will be used and intrinsic versus instrumental value orientations in the literature shall form the basis of our discussion. After the application of all the ethical approaches to the case studies, we conclude that without mitigation and the prospect of a future stable climate, assisted colonization will be involved in an inherently unethical process and a “move and lose it” outcome. With mitigation, there is wide-ranging ethical support for assisted colonization. (shrink)

Nelson Goodman has provided one of the most exciting advances in semiotic aesthetics in years in his recent book, Languages of Art. Among other theses that Goodman defends is the claim that pictures are elements of symbol systems to be understood in the way that languages are understood: that depiction and description are species of a common genus which is to be understood in terms of denotation. One of the consequences Goodman draws from his theory is that depiction is conventional: (...) the fact that a certain picture depicts a man is as much a matter of convention as the fact that a certain phrase describes him. This claim is interesting and exciting, but is it correct? Unfortunately, I do not think we are yet in a position to answer this last question, although I shall try to get nearer to an answer in this paper. (shrink)

Vocal imitation does not imply an ability to imitate nonvocal motor patterns. Exponential growth in frequency of a behaviour in a population does not imply diffusion by social learning. Distinguishing analogues from homologues of human culture will avoid confusion in discussion of evolution of culture. Original sources do not demonstrate social learning, imitation, or teaching of intentional beaching or lobtail feeding in cetaceans.
