Whereas there is extensive documentation that attribute framing influences the content of peoples thought, we generally know less about how it affects the processes assumed to precede those thoughts. While existing explanations for attribute framing effects rely completely on valence-based associative processing, the results obtained in the present study are also consistent with the notion that negative framing stimulates more effortful and thorough information processing than positive framing. Specifically, results from a simulated business decision-making experiment showed that decision makers receiving (...) negatively framed information had significantly better recall than those receiving positively framed information. Furthermore, decision makers in the negative framing condition were less confident than decision makers in the positively framed condition. Finally, compared to a no-framing condition, decision makers receiving positive framing deviated significantly more in evaluation than decision makers receiving negative framing did. (shrink)

In the present study it was shown that decision heuristics and confidence judgements play important roles in the building of preferences. Based on a dual-process account of thinking, the study compared people who did well versus poorly on a series of decision heuristics and overconfidence judgement tasks. The two groups were found to differ with regard to their information search behaviour in introduced multiattribute choice tasks. High performers on the judgemental tasks were less influenced in their decision processes by numerical (...) information format (probabilities vs. frequencies) compared to low performers. They also looked at more attributes and spent more time on the multiattribute choice tasks. The results reveal that performance on decision heuristics and overconfidence tasks has a bearing both on heuristic and analytic processes in multiattribute decision making. (shrink)

Henrich et al. convincingly caution against the overgeneralization of findings from particular human populations, but fail to apply their own compelling reasoning to our nearest living relatives, the great apes. Here we argue that rearing history is every bit as important for understanding cognition in other species as it is in humans.

Antimicrobial resistance (AMR) has become one of the defining challenges of the twenty-first century. Food production and farming are a key if troubling component of that challenge. Livestock production accounts for well over half of annual global consumption of antimicrobials, though the contribution of the sector to drug resistance is less clear. As a result, there is an injunction to act in advance of incontrovertible evidence for change. In this paper we engage with the role of market actors in the (...) precautionary regulation of farming practices and AMR threats. The paper takes the UK poultry sector as exemplary of an audit-led process that has, in recent years, achieved impressive reductions in antimicrobial use. Using qualitative interview data with farmers and veterinarians we chart the changing practices that have accompanied this reduction in treatments. We use this analysis to raise some cautions around audit-led systems of regulation. Audits can lock farms and animals into particular versions of farming and animal health; they can elevate harmful compensatory practices (including disinfectant uses); and they can reproduce an actuarial approach to an issue that does not fit the conventions of risk management. The paper presents the considerable successes that have been achieved over a short period of time in a livestock sector, while generating notes of caution concerning the audit-led management of livestock-related AMR threats.

The diversity in colour patterns on butterfly wings provides great potential for understanding how developmental mechanisms may be modulated in the evolution of adaptive traits. In particular, we discuss concentric eyespot patterns, which have been shown by surgical experiments to be formed in response to signals from a central focus. Seasonal polyphenism shows how alternate phenotypes can develop through environmental sensitivity mediated by ecdysteroid hormones, whereas artificial selection and single gene mutants demonstrate genetic variation influencing the number, shape, size, position, (...) and colour composition of the eyespots. The expression patterns of the regulatory gene Distal-less reveal that these changes can arise at several different developmental stages, and the phenotypes indicate that some forms of changed pattern may occur much more readily than others. Further study of the genes, of the developmental mechanisms, and of the functions of the patterns will provide novel insights about the evolution of morphological diversity.

Neuroenhancement involves the use of neurotechnologies to improve cognitive, affective or behavioural functioning, where these are not judged to be clinically impaired. Questions about enhancement have become one of the key topics of neuroethics over the past decade. The current study draws on in-depth public engagement activities in ten European countries giving a bottom-up perspective on the ethics and desirability of enhancement. This informed the design of an online contrastive vignette experiment that was administered to representative samples of 1000 respondents (...) in the ten countries and the United States. The experiment investigated how the gender of the protagonist, his or her level of performance, the efficacy of the enhancer and the mode of enhancement affected support for neuroenhancement in both educational and employment contexts. Of these, higher efficacy and lower performance were found to increase willingness to support enhancement. A series of commonly articulated claims about the individual and societal dimensions of neuroenhancement were derived from the public engagement activities. Underlying these claims, multivariate analysis identified two social values. The Societal/Protective highlights counter normative consequences and opposes the use enhancers. The Individual/Proactionary highlights opportunities and supports use. For most respondents these values are not mutually exclusive. This suggests that for many neuroenhancement is viewed simultaneously as a source of both promise and concern. (shrink)

There is now a rapidly expanding population of interlinked developmental biology databases on the World Wide Web that can be readily accessed from a desk‐top PC using programs such as Netscape or Mosaic. These databases cover popular organisms (Arabidopsis, Caenorhabditis, Drosophila, zebrafish, mouse, etc.) and include gene and protein sequences, lists of mutants, information on resources and techniques, and teaching aids. More complex are databases relating domains of gene expression to embryonic anatomy and these range from existing text‐based systems for (...) specific organs such as kidney, to a massive project under development, that will cover gene expression during the whole of mouse embryogenesis. In this brief article, we review selected examples of databases currently available, look forward to what will be available soon, and explain how to gain access to the World Wide Web. (shrink)

Miguel is an eighteen‐year‐old male transferred to Alamo Hospital for antivenom treatment after a rattlesnake bite while sleeping on railroad tracks. His “coyote,” an individual who guides undocumented people across the U.S. border from Mexico, dropped him off at a clinic. By the time Miguel was transferred from the clinic to Alamo, he was in complete paralysis and at risk for heart failure, requiring ventilator support to breathe. A person who receives treatment for a snake bite within one to two (...) hours has a 99 percent chance of recovery, but for Miguel, at least fifteen hours had already passed. A hospital ethicist at Alamo contacted the Mexican consulate, and together they arranged for Miguel's father to come to Alamo and make decisions for him. His physicians have determined that he is in a persistent vegetative state and can no longer benefit from hospital treatment. However, no long‐term care facility will accept him. Miguel is undocumented and unfunded. Miguel's father wishes to take his son home, but the cost of transporting him is high,and their home state in Mexico has no ventilator available for him and no consistent supply of electricity to run it. What should the hospital do? (shrink)

Conrad Hal Waddington was a British developmental biologist who mainly worked in Cambridge and Edinburgh, but spent the late 1930s with Morgan in California learning about Drosophila. He was the first person to realize that development depended on the then unknown activities of genes, and he needed an appropriate model organism. His major experimental contributions were to show how mutation analysis could be used to investigate developmental mechanisms in Drosophila, and to explore how developmental mutation could drive evolution, his other (...) deep interest. Waddington was, however, predominantly a thinker, and set out to provide a coherent framework for understanding the genetic bases of embryogenesis and evolution, developing his ideas in many books. Perhaps his best-known concept is the epigenetic landscape: here a ball rolls down a complex valley, making path choices. The rolling ball represents a cell’s development over time, while the topography represents the changing regulatory environment that controls these choices. In its later forms, the role of each feature in the landscape was controlled by the effects of sets of interacting genes, an idea underpinning contemporary approaches to systems biology. Waddington was the first developmental geneticist and probably the most important developmental biologist of the pre-molecular age. (shrink)

According to estimates more than 400 biobanks currently operate across Europe. The term ‘biobank’ indicates a specific field of genetic study that has quietly developed without any significant critical reflection across European societies. Although scientists now routinely use this phrase, the wider public is still confused when the word ‘bank’ is being connected with the collection of their biological samples. There is a striking lack of knowledge of this field. In the recent Eurobarometer survey it was demonstrated that even in (...) 2010 two-thirds of the respondents had never even heard about biobanks. The term gives the impression that a systematic collection of biological samples can constitute a ‘bank’ of considerable financial worth, where the biological samples, which are insignificant in isolation but are valuable as a collection, can be preserved, analysed and put to ‘profitable use’. By studying the practices of the numerous already existing biobanks, the authors address the following questions: to what extent does the term ‘biobank’ reflect the normative concept of using biological samples for the purposes of biomedical research? Furthermore, is it in harmony with the so far agreed legal–ethical consensus in Europe or does it deliberately pull science to the territory of a new, ambiguous commercial field? In other words, do biobanks constitute a medico-legal fiction or are they substantively different from other biomedical research protocols on human tissues? (shrink)

The value of any kind of data is greatly enhanced when it exists in a form that allows it to be integrated with other data. One approach to integration is through the annotation of multiple bodies of data using common controlled vocabularies or ‘ontologies’. Unfortunately, the very success of this approach has led to a proliferation of ontologies which itself creates obstacles to integration. The Open Biomedical Ontologies (OBO) consortium has set in train a strategy to overcome this problem. Existing (...) OBO ontologies, including the Gene Ontology, are undergoing a process of coordinated reform and new ontologies being created on the basis of an evolving set of shared principles governing ontology development. The result is an expanding family of ontologies designed to be interoperable, logically well-formed, and to incorporate accurate representations of biological reality. We describe the OBO Foundry initiative, and provide guidelines for those who might wish to become involved. (shrink)

The Patient Protection and Affordable Care Act of 2010 (ACA) contains many provisions intended to increase access to and lower the cost of health care by adopting public health measures. One of these promotes the use of at-work wellness programs by both providing employers with grants to develop these programs and also increasing their ability to tie the price employees pay for health insurance for participating in these programs and meeting specific health goals. Yet despite ACA's specific alteration of three (...) different statues which had in the past shielded employees from having to contribute to the cost of their health insurance based on their achieving employer-designated health markers, it chose to leave alone recently enacted rules implementing the Genetic Non-Discrimination Act (GINA), which prohibits employers from asking employees about their family health history in any context, including assessing their risk for setting wellness targets. This article reviews how both the changes made by ACA and the restrictions recently put place by GINA will affect the way employers are likely to structure Wellness Programs. It also considers how these changes reflect the competing social goals of both ACA, which seeks to expand access to the population by lowering costs, and GINA, which seeks to protect individuals from discrimination. It does so by analyzing both positive theories about how these new laws will function and normative theories explaining the likelihood of future friction between the interests of the population of the United States as a whole who are in need of increased and affordable access to health care, and of the individuals living in this country who risk discrimination, as science and medicine continue to make advances in linking genetic make-up to risk of future illness.

The passing of the Patient Protection and Affordable Care Act is a triumph for the field of public health. Its inclusion of many provisions intended to prevent illness and promote health endorses the core belief of public health as expressed by Dr. Georges Benjamin, the long-time executive director of the American Public Health Association, in a Washington Post opinion piece praising ACA for “provid[ing] care as far upstream as possible… [in order to] reduce costs by identifying problems early and then (...) managing them to reduce or eliminate the need for more costly care in the future.” In this article, I consider the conflict between ACA’s adoption of public health goals seeing population health and societal interests in protecting individuals from discrimination based on their health. The article focuses on one aspect of ACA which seeks to lower the costs to employers who provide health insurance for their employees by making it easier for them to offer their employees substantial incentives for participating in and meeting the goals of employer-sponsored Wellness Programs.

An ontology is a domain of knowledge structured through formal rules so that it can be interpreted and used by computers. Ontologies are becoming increasingly important in bioinformatics because they can be linked to the information in databases and their knowledge then used to query the databases. Typical examples in current use are the Gene Ontology, which incorporates much of our knowledge about gene products, and ontologies of developmental anatomy, which, for example, facilitate tissue‐based queries to gene expression databases both (...) textually and spatially. This article considers the production, formulation and types of bio‐ontologies together with the reasons why they are so useful. © BioEssays 25:501–506, 2003. © 2003 Wiley Periodicals, Inc. (shrink)

In 2011, Peterson suggested that the main reason why C.H. Waddington was essentially ignored by the framers of the modern evolutionary synthesis in the 1950s was because they were Cartesian reductionists and mathematical population geneticists while he was a Whiteheadian organicist and experimental geneticist who worked with Drosophila. This paper suggests a further reason that can only be seen now. The former defined genes and their alleles by their selectable phenotypes, essentially the Mendelian view, while Waddington defined a gene through (...) its functional role as determined by genetic analysis, a view that foresaw the modern view that a gene is a DNA sequence with some function. The former were interested in selection, while Waddington focused on variation. The differences between the two views of a gene are briefly considered in the context of systems biology. (shrink)

Because the kidney (metanephros) starts to function before completing development, its patterning and morphogenesis need to be closely integrated with its growth. This is achieved by blast cells at the kidney periphery generating new nephrons that link up to the extending collecting‐duct arborisation, while earlier‐formed and more internal nephrons are maturing and beginning to filter serum. This pattern of development requires that cell division and apoptosis be co‐ordinated in the various kidney compartments (collecting‐ducts, blast cells, metanephric mesenchyme, nephrons and vascular (...) system). The underlying regulatory networks for cell proliferation are beginning to be unravelled, mainly through expression studies, mutation analysis and experimentation in vitro. This article summarises current knowledge of kidney growth and apoptosis, and analyses some of the 80 or so ligand–receptor pairings that seem to sustain development and growth. It also points to some unanswered questions, the most intriguing being what role does apoptosis play during normal kidney development? BioEssays 24:72–82, 2002. © 2002 John Wiley & Sons, Inc.

Although the segregation of mesenchyme into distinct aggregates is the first step in the development of a range of tissues that includes bones, somites, feathers and nephrons, we still know very little about the mechanisms by which this happens. There are two obvious types of explanation: first, that there are global pre‐patterns within the mesenchyme whose molecular expression leads to tissue fragmentation and, second, that the condensations arise spontaneously through the local morphogenetic abilities of the cells. The only known mechanism (...) for the latter possibility is cell traction and this paper suggests that current studies are compatible with traction playing a primary role in the formation of nephrogenic condensations in the developing kidney and the separation of somites, but not for the generation of feather rudiments where there is evidence of a prepattern of adhesivity.

New observations by Hatini et al.(1) on the ‘winged helix’ transcription factor BF‐2 will make us change our views about kiney development. This gene is only expressed in stromal cells associated with the kidney medulla and cortex, but the BF‐2 knockout has unexpected abnormalities. Although the stromal cells appear normal, the kidney is small, the ducts have limited branching and, instead of the many normal nephrogenic aggregates, there are relatively few large mesenchymal aggregates that fail to differentiate. The stromal cells (...) thus seem to produce factors regulating other aspects of kidney development, while the abnormalities highlight a series of unsolved problems in kidney morphogenesis. (shrink)

In recent years, explanations of primate cognition highlighted clever arguments, rather than different ability. In the target article, definitions unify, explanations rely on basic nervous system functioning, theory is built on data that fit, and the emphasis is on evolutionary continuities. This commentary describes complexities inherent in the development of empathy that are not accounted for in Preston & de Waal's theory.
