The behavior of individuals currently living will generally have long-term consequences that affect the well-being of those who will come to live in the future. Intergenerational interdependencies of this nature raise difficult moral issues because only the current generation is in a position to decide on actions that will determine the nature of the world in which future generations will live. Although most are willing to attach some weight to the interests of future generations, many would argue that it is (...) not necessary to treat these interests as equivalent to those of the current generation. A common approach in this context is to use a system of discounting to evaluate future benefits and harms. This paper assesses the logic of discounting drawing on the writings of economists and philosophers. Much of the economic literature concerns the choice of an appropriate social discount rate. The social discount rate can be taken to reflect beliefs about the rights of future generations, a subject that has been extensively debated in the phioosophic literature. The writings of both economists and philosophers concerned with the weight to attach to the interests of future generations are reviewed and evaluated in this paper and the implications for environmental policy are discussed.

There has been much discussion of changing agricultural structure in the United States. In this paper, the author reviews some of the factors contributing to structural change in the United States and describes the policies adopted by the European Community with respect to agricultural structure. The European experience with structural policies suggests that this approach is not very promising for the United States where no specific structural policies exist. The argument developed in this paper is that structural changes in agriculture (...) are simply one example of economic adjustment in a capitalist economy, that economic adjustments are generally desirable although they are not costless, and that discussions of agricultural structure should focus on methods to alleviate the costs of adjustment rather than on efforts to prevent change.

Property rights are important institutions that influence economic performance and reflect the historical, cultural, and political realities of particular societies. Drawing on a variety of concepts from legal and economic studies, a framework for explaining the origin and evolution of property rights is developed and applied to the specific case of changing ground water rights in Nebraska. The Nebraska case is an interesting example of reliance on local control in regulating water use. Despite the importance of local initiatives in ground (...) water management, this case also illustrates the need for external support from the judicial and legislative systems. The evolution of ground water property rights in Nebraska, as in other parts of the United States, has been conditioned by historical circumstances and changing values and attitudes as well as by economic and political forces.

The Common Agricultural Policy (CAP) of the European Community (EC) has been criticized for causing a misallocation of resources, inequitable income transfers, and enormous budgetary costs. The purpose of this paper is to examine the political economy of agriculture and agricultural policy in the EC. The results of the analysis indicate that conflicts between national political objectives and broader, community-wide concerns are important factors in the performance of EC agriculture. The pressures for reform of the CAP will lead to modification (...) of the system, but changes in EC agricultural policy are likely to be moderate because of the inherent inertia of the policy-making process. As a result, the agricultural system in the EC will probably continue to evolve in an atmosphere of crisis with most reforms directed at symptoms rather than fundamental problems. (shrink)

Background Speaking up to safeguard patients is a crucial ethical and moral obligation for nurses, but it is also a difficult and potentially dangerous component of nursing work. Health advocacy is gaining impetus in the medical literature, despite being hampered by barriers resulting in many nurses in Ghana remaining mute when faced with advocacy-required situations. We explored situations that thwart nurses from performing their health advocacy role. Research question What would cause nurses to take no action when they witness situations (...) that require them to act as health advocates for their clients or communities? Research Design An inductive, descriptive qualitative design was used to collect and analyse data on barriers that prevent nurses from practising their health advocacy role in Ghana. Individual one-on-one in-depth interviews were conducted using a semi-structured interview guide. The data were analysed using qualitative content analysis. Participants and research context Twenty-four professional nurses and midwives registered with the Nursing and Midwifery Council were recruited from three regional hospitals in Ghana. These public hospitals were chosen from the upper, middle and coastal regions. Ethical considerations The UKZN Ethics Review Committee in South Africa and the GHS Ethics Review Committee in Ghana both gave their approval for this study. Findings Intrapersonal barriers, interpersonal barriers, and structural barriers emerged as major obstacles that nurses experience when performing their health advocacy role. Conclusions Barriers to health advocacy have undermined nurses' ability to function as health advocates and are preventing them from utilising their health advocacy position in nursing practise. Giving nursing students positive role models in the classroom and in the clinic can help them become more effective health advocates. (shrink)

To examine Heidegger's pedagogy is to be invited into a particular era and cultural reality—starting in Weimar Germany and progressing into the rise and fall of the Third Reich. In his attempt to reform the German university in a strictly hierarchical, authoritarian and nationalistic mold, Heidegger addressed one group of students and professors and not another. The petit‐bourgeois student and the future philosophers he invited with his ‘logic of recruitment’ into the corps of instructors, would share his coded language with (...) its built‐in taboos and censorship. The result was a rhetoric of absolute self‐reference and a semiotic of pure propaganda, based on the evocation of the ancient Greeks in which the philosopher meant to project all that was properly Germanic. Heidegger's rhetoric is exclusionary; its politics and its philosophy are interpenetrating. His lecture courses grew increasingly poeticized, and thus mired in ambiguity, evasion, elision, avoidance, grandiloquence. Parallels are drawn in this essay between Heidegger and our time. Is Heidegger's insistence on autocratic controls within the German university comparable to the corporate positions taken today by some educators? How does the shifting relation between disciplines affect the role of the specialist? How might the sciences morales or humanities, along with the much maligned ‘humanism’, be redefined morally and holistically? (shrink)

Hegel’s discussion of sense certainty in the Phenomenology of Spirit contains the following, humorous, observation.

The essay distils from Badiou's writing a pedagogy based on his theories of knowledge and truth, as brought to bear on poetry and the arts. By following Badiou's implicit ontology of learning, which presupposes a dynamic and passionate engagement with a concrete situation, the essay argues that Badiou's view of modernity, in particular, contributes greatly to the educational topic, and offers an alternative teaching paradigm to the outmoded schools of criticism of the 20th century. It also argues that the concept (...) of universalism in education, as against identitarian particularism, is further evinced from a discussion of Badiou's study of St. Paul. (shrink)

The Philosophy of Nature does not begin, as we expect, with nature. Instead, Hegel describes the practical and theoretical approaches we make to nature as philosophers; that is, in thought and, metaphorically, with our teeth. This ledge on the climb into nature is often overlooked as we rush from the logic into space and time. There may be two reasons for this. The first is a natural expectation that a philosophy of nature begin by describing natural phenomena, not our approaches (...) to them. The second is that the terms ‘practical’ and ‘theoretical’, familiar from the Logic and Philosophy of Spirit, may seem at first glance to be out of place here. Whatever the reason, these paragraphs have not been discussed at any length in the secondary literature. (shrink)

Non-consensual organ procurement from prisoners in China raises serious questions regarding the ethics of Chinese transplant research. In their article, published in this issue of JME, Higgins and colleagues address these questions through the lens of publication ethics. They argue that, ‘while there are potentially compelling justifications for use [of unethical research] under some circumstances, these justifications fail when unethical practices are ongoing’.1 Consequently, they recommend non-publication of Chinese transplant research and call for a mass retraction of the articles identified (...) in their review.2 To support their argument, Higgins and colleagues appeal to internationally recognised guidelines from the WHO3 and the World Medical Association, which assert that ‘executed prisoners must not be considered as organ and/or tissue donors’ due to the inability to acquire valid consent.4 Failing to declare an immediate publishing moratorium for transplant research involving prisoners in China, they argue, ‘undermines efforts to stop transplant-related human rights abuses, taints the evidence base, and renders those who publish and use the research complicit in the continuing harm’.5 We agree with Higgins and colleagues that non-consensual organ procurement from prisoners in China is a crime against humanity. Ongoing human rights violations in Chinese prisons are well documented and universally condemned. We also agree that the subsequent use of data acquired from unethical research is morally complex. Nonetheless, Higgins and colleagues’ arguments leave us with three …. (shrink)

In the early years of the 20th century, physicists bumped into the quantum level of observation. They began to experience problems with their observations which, disturbingly, seemed to suggest as much about the underlying psychological foundation of the scientist as about the universe—or worse, which suggested that these two might somehow be internally related. Heisenberg and Gödel, among others, raised questions that science was hard pressed to answer. Quantum wave theory and relativity involved the observer in the observation, but paradoxes (...) seemed to result from attempts to describe how they are related. (shrink)

In this paper we shed new light on the Argument from Disagreement by putting it to test in a computer simulation. According to this argument widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by any moral facts, either because no such facts exist or because they are epistemically inaccessible or inefficacious for some other reason. Our simulation shows that if our moral opinions were influenced at least a little bit by moral facts, we (...) would quickly have reached consensus, even if our moral opinions were affected by factors such as false authorities, external political shifts, and random processes. Therefore, since no such consensus has been reached, the simulation gives us increased reason to take seriously the Argument from Disagreement. Our conclusion is however not conclusive; the simulation also indicates what assumptions one has to make in order to reject the Argument from Disagreement. The simulation algorithm we use builds on the work of Hegselmann and Krause (J Artif Soc Social Simul 5(3); 2002, J Artif Soc Social Simul 9(3), 2006). (shrink)

The use of social media as a recruitment tool for research with humans is increasing, and likely to continue to grow. Despite this, to date there has been no specific regulatory guidance and there has been little in the bioethics literature to guide investigators and institutional review boards faced with navigating the ethical issues such use raises. We begin to fill this gap by first defending a nonexceptionalist methodology for assessing social media recruitment; second, examining respect for privacy and investigator (...) transparency as key norms governing social media recruitment; and, finally, analyzing three relatively novel aspects of social media recruitment: the ethical significance of compliance with website “terms of use”; the ethics of recruiting from the online networks of research participants; and the ethical implications of online communication from and between participants. Two checklists aimed at guiding investigators and IRBs through the ethical issues are included as appendices. (shrink)

It is not uncommon for multiple clinical trials at the same institution to recruit concurrently from the same patient population. When the relevant pool of patients is limited, as it often is, trials essentially compete for participants. There is evidence that such a competition is a predictor of low study accrual, with increased competition tied to increased recruitment shortfalls. But there is no consensus on what steps, if any, institutions should take to approach this issue. In this article, we argue (...) that an institutional policy that prioritises some trials for recruitment ahead of others is ethically permissible and indeed prima facie preferable to alternative means of addressing recruitment competition. We motivate this view by appeal to the ethical importance of minimising the number of studies that begin but do not complete, thereby exposing their participants to unnecessary risks and burdens in the process. We then argue that a policy of prioritisation can be fair to relevant stakeholders, including participants, investigators and funders. Finally, by way of encouraging and helping to frame future debate, we propose some questions that would need to be addressed when identifying substantive ethical criteria for prioritising between studies.

The Kyoto Protocol on global warming has provoked great controversy in part because it calls for heavier burdens on wealthy countries than on developing countries in the effort to control climate change. The U.S. Senate voted unanimously to oppose any agreement that does not require emissions reductions in low-income countries. The ethics of this position are examined in this paper which shows that there are good moral reasons for supporting the provisions of the Kyoto Protocol. Such a conclusion follows easily (...) from considerations of distributive justice but can also be supported by more narrowly self-interested arguments. (shrink)

Interest in science and math plays an important role in encouraging STEM motivation and career aspirations. This interest decreases for girls between late childhood and adolescence. Relatedly, positive mentoring experiences with female teachers can protect girls against losing interest. The present study examines whether visitors to informal science learning sites differ in their expressed science and math interest, as well as their science and math stereotypes following an interaction with either a male or female educator. Participants were visitors to one (...) of four ISLS in the United States and United Kingdom. Following an interaction with a male or female educator, they reported their math and science interest and responded to math and science gender stereotype measures. Female participants reported greater interest in math following an interaction with a female educator, compared to when they interacted with a male educator. In turn, female participants who interacted with a female educator were less likely to report male-biased math gender stereotypes. Self-reported science interest did not differ as a function of educator gender. Together these findings suggest that, when aiming to encourage STEM interest and challenge gender stereotypes in informal settings, we must consider the importance of the gender of educators and learners.

Why do humans make music? Theories of the evolution of musicality have focused mainly on the value of music for specific adaptive contexts such as mate selection, parental care, coalition signaling, and group cohesion. Synthesizing and extending previous proposals, we argue that social bonding is an overarching function that unifies all of these theories, and that musicality enabled social bonding at larger scales than grooming and other bonding mechanisms available in ancestral primate societies. We combine cross-disciplinary evidence from archeology, anthropology, (...) biology, musicology, psychology, and neuroscience into a unified framework that accounts for the biological and cultural evolution of music. We argue that the evolution of musicality involves gene–culture coevolution, through which proto-musical behaviors that initially arose and spread as cultural inventions had feedback effects on biological evolution because of their impact on social bonding. We emphasize the deep links between production, perception, prediction, and social reward arising from repetition, synchronization, and harmonization of rhythms and pitches, and summarize empirical evidence for these links at the levels of brain networks, physiological mechanisms, and behaviors across cultures and across species. Finally, we address potential criticisms and make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music. (shrink)

Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that (...) remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant are rarely preserved, and decay-prone structures can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. Organisms decayed experimentally in seawater have been used as direct analogs for soft-bodied fossil taxa, with fossils representing a snapshot of a particular stage of decay. We argue that numerous geological and biological processes account for fossilization and that all of these should be considered when reconstructing extinct organisms. (shrink)

Institutional review boards, tasked with facilitating ethical research, are often pulled in competing directions. In what we call the protection-inclusion dilemma, we acknowledge the tensions IRBs face in aiming to both protect potential research participants from harm and include under-represented populations in research. In this manuscript, we examine the history of protectionism that has dominated research ethics oversight in the United States, as well as two responses to such protectionism: inclusion initiatives and critiques of the term vulnerability. We look at (...) what we know about IRB decision-making in relation to protecting and including “vulnerable” groups in research and examine the lack of regulatory guidance related to this dilemma, which encourages protection over inclusion within IRB practice. Finally, we offer recommendations related to how IRBs might strike a better balance between inclusion and protection in research ethics oversight. (shrink)

The injunction to “analyze the way you randomize” is well known to statisticians since Fisher advocated for randomization as the basis of inference. Yet even those convinced by the merits of randomization-based inference seldom follow this injunction to the letter. Bernoulli randomized experiments are often analyzed as completely randomized experiments, and completely randomized experiments are analyzed as if they had been stratified; more generally, it is not uncommon to analyze an experiment as if it had been randomized differently. This article (...) examines the theoretical foundation behind this practice within a randomization-based framework. Specifically, we ask when is it legitimate to analyze an experiment randomized according to one design as if it had been randomized according to some other design. We show that a sufficient condition for this type of analysis to be valid is that the design used for analysis should be derived from the original design by an appropriate form of conditioning. We use our theory to justify certain existing methods, question others, and finally suggest new methodological insights such as conditioning on approximate covariate balance. (shrink)

Folie à deux is the transference of delusional ideas from one 'primary' individual to one or more 'secondary' individuals (Lasègue & Falret, 1877). However, it is difficult to investigate experimentally because often only one patient is identified as delusional. We investigated whether hypnosis could model the experiences of the secondary in this delusion. Our primary was a confederate, who displayed two delusional beliefs and attempted to transmit them to hypnotised subjects. We manipulated the status of the confederate so that they (...) were portrayed as either "credible" or merely "interesting". Many high hypnotisable individuals adopted the confederate's beliefs and confabulated evidence in support of them. Also, subjects who interacted with a credible confederate extended their delusions beyond those displayed by the confederate. We discuss the strengths and limitations of this approach and suggest ways to improve the validity of this model. (shrink)

Patient outcome after serious brain injury is highly variable. Following a period of coma, some patients recover while others progress into a vegetative state (unresponsive wakefulness syndrome) or minimally conscious state. In both cases, assessment is difficult and misdiagnosis may be as high as 43%. Recent advances in neuroimaging suggest a solution. Both functional magnetic resonance imaging and electroencephalography have been used to detect residual cognitive function in vegetative and minimally conscious patients. Neuroimaging may improve diagnosis and prognostication. These techniques (...) are beginning to be applied to comatose patients soon after injury. Evidence of preserved cognitive function may predict recovery, and this information would help families and health providers. Complex ethical issues arise due to the vulnerability of patients and families, difficulties interpreting negative results, restriction of communication to “yes” or “no” answers, and cost. We seek to investigate ethical issues in the use of neuroimaging in behaviorally nonresponsive patients who have suffered serious brain injury. The objectives of this research are to: (1) create an approach to capacity assessment using neuroimaging; (2) develop an ethics of welfare framework to guide considerations of quality of life; (3) explore the impact of neuroimaging on families; and, (4) analyze the ethics of the use of neuroimaging in comatose patients.

The recent discovery of microRNAs (miRNAs) in unicellular eukaryotes, including miRNAs known previously only from animals or plants, implies that miRNAs have a deep evolutionary history among eukaryotes. This contrasts with the prevailing view that miRNAs evolved convergently in animals and plants. We re‐evaluate the evidence and find that none of the 73 plant and animal miRNAs described from protists meet the required criteria for miRNA annotation and, by implication, animals and plants did not acquire any of their respective miRNA (...) genes from the crown ancestor of eukaryotes. Furthermore, of the 159 novel miRNAs previously identified among the seven species of unicellular protists examined, only 28 from the algae Ectocarpus and Chlamydomonas, meet the criteria for miRNA annotation. Therefore, at present only five groups of eukaryotes are known to possess miRNAs, indicating that miRNAs have evolved independently within eukaryotes through exaptation of their shared inherited RNAi machinery.

Schools are ideal settings for implementing multi-component programs to prevent and control childhood obesity. Thoughtful improvements to proven strategies, coupled with careful evaluation, can contribute to accumulation of evidence needed to design and implement the next generation of optimal interventions.

The obesity epidemic among children and adolescents in the United States continues to worsen. The most recent analysis of data from the National Health and Nutrition Examination Survey showed that the prevalence of overweight among children and adolescents – defined as a Body Mass Index at or above the 95th percentile on gender-specific BMI-for-age growth charts developed by the Centers for Disease Control and Prevention – increased significantly between 1999-2000 and 2003-2004. Over this period, the prevalence of overweight among children (...) and adolescents aged 2-19 increased 23% – from 13.9% to 17.1%. In 2003-2004, 18.8% of children aged 6-11 and 17.4% of adolescents aged 12-19 were overweight. Roughly comparable proportions of each age group were considered to be at risk of becoming overweight.
