Thelen and her colleagues' model overemphasizes the role of action in cognitive development. Recent research has shown that infants do not have to be trained to reach for a hidden object. By 7.5 months of age, infants can recall the location of a hidden object with no practice trials. Thelen at al.'s goal to design a parsimonious account of A-not-B behaviors was successful, but at the expense of focusing primarily on implicit and ignoring explicit memory.

For over 20 years, the concept of “food deserts” has served as an evocative metaphor, signifying spatialized patterns of injustice associated with low access to nutritious foods through retail and social exclusion. Yet in spite of its pithy appeal, scholars and activists increasingly critique the food desert concept as stigmatizing, inaccurate, and insufficient to characterize entrenched structural inequities. These well-founded critiques demonstrate a convincing need to reframe approaches to spatialized food injustice. We argue that food desert maps, which aim to (...) visually illustrate food inequality, can reproduce problematic assumptions, stigmas, and inaccuracies that form the crux of scholarly critiques. For example, food desert maps typically overlook community assets and also utilize decontextualized and overdetermined indicators, such as proximity to supermarkets and transportation access. Although we acknowledge the contributions of food desert maps, in this paper we propose a reimagining of food access mapping. To illustrate our argument, we present a course-based food justice mapping study in Providence, Rhode Island. Our project draws inspiration from studies that interrogate the deficit-oriented framing of food deserts, as well as several alternative mapping practices: critical cartography and counter-mapping, community asset mapping, participatory geographic information systems, and radical cartography. We suggest these alternative mapping approaches have potential to move practitioners and viewers beyond the desolate “desert” vantage point and toward a more textured understanding of community food access that inspires engaged exploration.

Implicit processes almost certainly preceded explicit processes in our evolutionary history, so they are likely to be more resistant to disruption according to the principles of evolutionary biology [Reber, A. S. . The cognitive unconscious: An evolutionary perspective. Consciousness and Cognition, 1, 93–133.]. Previous work . Knowledge, nerves and know-how: The role of explicit versus implicit knowledge in the breakdown of a complex motor skill under pressure. British Journal of Psychology, 83, 343–358.]) has shown that implicitly learned motor skills remain (...) stable under psychological pressure and concurrent cognitive demands, and recently [Poolton, J. M., Masters, R. S. W., & Maxwell, J. P. . Passing thoughts on the evolutionary stability of implicit motor behaviour: Performance retention under physiological fatigue. Consciousness and Cognition, 16, 456–468.] showed that they also remain stable under conditions of anaerobic fatigue that would have significantly challenged the survival skills of our ancestors. Here we examine the stability of an implicitly learned motor skill under fatigue conditions that primarily tax a different physiological system , but which have equally strong evolutionary connotations. Participants acquired a throwing task by means of an errorless learning method or an errorful method. Motor performance in the errorless condition, but not the errorful condition, remained stable following an exhaustive VO2 max. running test. Our findings replicate and extend the work of Poolton et al., providing further support for Reber’s evolutionary distinction between implicit and explicit processes. (shrink)

Participants struck 500 golf balls to a concealed target. Outcome feedback was presented at the subjective or objective threshold of awareness of each participant or at a supraliminal threshold. Participants who received fully perceptible feedback learned to strike the ball onto the target, as did participants who received feedback that was only marginally perceptible . Participants who received feedback that was not perceptible showed no learning. Upon transfer to a condition in which the target was unconcealed, performance increased in both (...) the subjective and the objective threshold condition, but decreased in the supraliminal condition. In all three conditions, participants reported minimal declarative knowledge of their movements, suggesting that deliberate hypothesis testing about how best to move in order to perform the motor task successfully was disrupted by the impoverished disposition of the visual outcome feedback. It was concluded that sub-optimally perceptible visual feedback evokes implicit processes. (shrink)

Stem cells are likely to be used as an alternate source of biological material for neural transplantation to treat Parkinson’s disease in the not too distant future. Among the several ethical criteria that must be fulfilled before proceeding with clinical research, a favourable benefit to risk ratio must be obtained. The potential benefits to the participant and to society are evaluated relative to the risks in an attempt to offer the participants a reasonable choice. Through examination of preclinical studies transplanting (...) stem cells in animals and the transplantation of fetal tissue in patients with Parkinson’s disease, a current set of potential benefits and risks for neural transplantation of stem cells in clinical research of Parkinson’s disease are derived. The potential benefits to research participants undergoing stem cell transplantation are relief of parkinsonian symptoms and decreasing doses of parkinsonian drugs. Transplantation of stem cells as a treatment for Parkinson’s disease may benefit society by providing knowledge that can be used to help determine better treatments in the future. The risks to research participants undergoing stem cell transplantation include tumour formation, inappropriate stem cell migration, immune rejection of transplanted stem cells, haemorrhage during neurosurgery and postoperative infection. Although some of these risks are general to neurosurgical transplantation and may not be reduced for participants, the potential risk of tumour formation and inappropriate stem cell migration must be minimised before obtaining a favourable potential benefit to risk calculus and to provide participants with a reasonable choice before they enrol in clinical studies.

This book is intended as an equivalent to or substitute for that "more reflective reading" which Rousseau considered essential to an understanding of his ideas. It is designed to complement perusal of the texts themselves, and the arrangement is such that chapters on each of Rousseau's major writings can be consulted separately or the commentary may be read through in sequence. The author's purpose is not to present a "key" to Rousseau's political philosophy, but rather to explore the works themselves (...) in an effort to reveal Rousseau's "system," from which the reader may then draw his own conclusions. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Social scientists have begun elucidating the variables that influence public trust in science, yet little is known about hype in biotechnology and its effects on public trust. Many scholars claim that hyping biotechnology results in a loss of public trust, and possibly public enthusiasm or support for science, because public expectations of the biotechnological promises will be unmet. We argue for the need for empirical research that examines the relationships between hype, public trust, and public enthusiasm/support. We discuss the complexities (...) in designing empirical studies that provide evidence for a causal link between hype, public trust, and public enthusiasm/support, but also illustrate how this may be remedied. Further empirical research on hype and public trust is needed in order to improve public communication of science and to design evidence-based education on the responsible conduct of research for scientists. We conclude that conceptual arguments made on hype and public trust must be nuanced to reflect our current understanding of this relationship. (shrink)

Many potential therapeutic agents are discarded before they are tested in humans. These are not quack medications. They are drugs and other interventions that have been developed by responsible scientists in respectable companies or universities and are often backed up by publications in peer-reviewed journals. These possible treatments might ease suffering and prolong the lives of innumerable patients, yet they have been put aside. In this paper, we outline a novel mechanism—the Plutocratic Proposal—to revive such neglected research and fund early (...) phase clinical trials. The central idea of the Proposal is that any patient who rescues a potential therapeutic agent from neglect by funding early phase clinical trials should be offered a place on the trial. (shrink)

There is a widely acknowledged shortage of and an increasing demand for transplantable human organs and tissues (e.g., kidney, heart, lung, liver, cornea) in developed and developing countries around the world. In response to this need, Lott and Savulescu (2007) propose the creation of a human embryonic stem (hESC) bank to facilitate the equitable and efficient dissemination of human leukocyte anti- gen (HLA) matched tissues and organs to patients in need of replacement. Although not an unreasonable proposal, the authors go (...) on to make a much stronger claim. They argue that hESCs are such important tools for addressing the massive unmet global need for organs that it is ethically justified to require mandatory banking of spare embryos, and they argue for the use of financial (or other) inducements to procure embryos for the derivation of hESCs.

Science lessons using inquiry only or history of science with inquiry were used for explicit reflective nature of science instruction for second-, third-, and fourth-grade students randomly assigned to receive one of the treatments. Students in both groups improved in their understanding of creative NOS, tentative NOS, empirical NOS, and subjective NOS as measured using VNOS-D as pre- and post-test surveys. Social and cultural context of science was not accessible for the students. Students in second, third, and fourth grades were (...) able to attain adequate views of empirical NOS, the role of observation and inference, creative and imaginative NOS, and subjective NOS. Students were not able to express adequate views of socially and culturally embedded NOS. Most gains in NOS eroded by the next school year, except for tentative NOS for both groups and creative NOS for the inquiry group. (shrink)

In an appendix, Professor Masters examines the continuity of the several themes of the Platonic-Hermetic tradition as they occur in the five books of the Rabelaisian corpus.

Stem cell tourism is a growing industry in which patients pursue unproven stem cell therapies for a wide variety of illnesses and conditions. It is a challenging market to regulate due to a number of factors including its international, online, direct-to-consumer approach. Calls to provide education and information to patients, their families, physicians, and the general public about the risks associated with stem cell tourism are mounting. Initial studies examining the perceptions of patients who have pursued stem cell tourism indicate (...) many are highly critical of the research and regulatory systems in their home countries and believe them to be stagnant and unresponsive to patient needs. We suggest that educational material should include an explanation of the translational research process, in addition to other aspects of stem cell tourism, as one means to help promote greater understanding and, ideally, curb patient demand for unproven stem cell interventions. The material provided must stress that strong scientific research is required in order for therapies to be safe and have a greater chance at being effective. Through an analysis of educational material on stem cell tourism and translational stem cell research from patient groups and scientific societies, we describe essential elements that should be conveyed in educational material provided to patients. Although we support the broad dissemination of educational material on stem cell translational research, we also acknowledge that education may simply not be enough to engender patient and public trust in domestic research and regulatory systems. However, promoting patient autonomy by providing good quality information to patients so they can make better informed decisions is valuable in itself, irrespective of whether it serves as an effective deterrent of stem cell tourism.

Stem cell tourism is a form of medical tourism in which patients travel to receive unproven or untested stem cell-based interventions for many different diseases and conditions. A few studies indicate that patients and the public have several reasons for seeking these treatments for themselves or for their loved ones. Among these are the feeling of not having any other clinical options left, distrust of or frustration with their home country’s health care system, and a perception that their home country (...) has a burdensome or sluggish regulatory system for the approval of novel stem cell therapies. These last two viewpoints may contribute to a certain sense of distrust of regulatory agencies governing the conduct of clinical research, and perhaps the perception of a health care system that seems unresponsive to the needs of patients suffering from severe conditions.

In the US, stem cell research is at a moral impasse—many see this research as ethically mandated due to its potential for ameliorating major diseases, while others see this research as ethically impermissible because it typically involves the destruction of embryos and use of ova from women. Because their creation does not require embryos or ova, induced pluripotent stem cells offer the most promising path for addressing the main ethical objections to stem cell research; however, this technology is still in (...) development. In order for scientists to advance induced pluripotent stem cell research to a point of translational readiness, they must continue to use ova and embryos in the interim. How then are we to ethically move forward with stem cell research? We argue that there is personal integrity and value in adopting a ‘moral compromise’ as a means for moving past the moral impasse in stem cell research. In a moral compromise, each party concedes part of their desired outcome in order to engage in a process that respects the values and desires of all parties equitably. Whereas some contend that moral compromise in stem cell research necessarily involves self-contradiction or loss of personal integrity, we argue that in the US context, stem cell research satisfies many of the key pre-conditions of an effective moral compromise. To illustrate our point, we offer a model solution wherein eggs and embryos are temporarily used until non-egg and non-embryonic sources of pluripotent stem cells are developed to a state of translational readiness.

When labeling an infectious disease, officially sanctioned scientific names, e.g., “H1N1 virus,” are recommended over place-specific names, e.g., “Spanish flu.” This is due to concerns from policymakers and the WHO that the latter might lead to unintended stigmatization. However, with little empirical support for such negative consequences, authorities might be focusing on limited resources on an overstated issue. This paper empirically investigates the impact of naming against the current backdrop of the 2019–2020 pandemic. The first hypothesis posited that using place-specific (...) names associated with China leads to greater levels of sinophobia, the negative stigmatization of Chinese individuals. The second hypothesis posited that using a scientific name leads to increased anxiety, risk aversion, beliefs about contagiousness of the virus, and beliefs about mortality rate. Results from two preregistered studies [N = 504; N = 412], conducted across three countries with the first study during the early outbreak and the second study at a later stage of the pandemic, found no evidence of any adverse effects of naming on sinophobia and strong support for the null hypothesis using Bayesian analyses. Moreover, analyses found no impact of naming on anxiety, risk aversion, beliefs about contagiousness of the virus, or beliefs about mortality rate, with mild to strong support for the null hypothesis across outcomes. Exploratory analyses also found no evidence for the effect of naming being moderated by political affiliation. In conclusion, results provide no evidence that virus naming impacted individual’s attitudes toward Chinese individuals or perceptions of the virus, with the majority of analyses finding strong support for the null hypothesis. Therefore, based on the current evidence, it appears that the importance given to naming infectious diseases might be inflated. (shrink)

Background: In biomedical research, there have been numerous scandals highlighting conflicts of interest (COIs) leading to significant bias in judgment and questionable practices. Academic institutions, journals, and funding agencies have developed and enforced policies to mitigate issues related to COI, especially surrounding financial interests. After a case of editorial COI in a prominent bioethics journal, there is concern that the same level of oversight regarding COIs in the biomedical sciences may not apply to the field of bioethics. In this study, (...) we examined the availability and comprehensiveness of COI policies for authors, peer reviewers, and editors of bioethics journals. Methods: After developing a codebook, we analyzed the content of online COI policies of 63 bioethics journals, along with policy information provided by journal editors that was not publicly available. Results: Just over half of the bioethics journals had COI policies for authors (57%), and only 25% for peer reviewers and 19% for editors. There was significant variation among policies regarding definitions, the types of COIs described, the management mechanisms, and the consequences for noncompliance. Definitions and descriptions centered on financial COIs, followed by personal and professional relationships. Almost all COI policies required disclosure of interests for authors as the primary management mechanism. Very few journals outlined consequences for noncompliance with COI policies or provided additional resources. Conclusion: Compared to other studies of biomedical journals, a much lower percentage of bioethics journals have COI policies and these vary substantially in content. The bioethics publishing community needs to develop robust policies for authors, peer reviewers, and editors and these should be made publicly available to enhance academic and public trust in bioethics scholarship.
