Although there is a growing recognition that older adults and those with extensive comorbid conditions undergo cancer screening too frequently, there is little information about patients’ perceptions regarding cessation of cancer screening. Information on older adults’ views of screening cessation would be helpful both for clinicians and for those designing interventions to reduce overscreening.

The discovery of conjunctive causes--factors that act in concert to produce or prevent an effect--has been explained by purely covariational theories. Such theories assume that concomitant variations in observable events directly license causal inferences, without postulating the existence of unobservable causal relations. This article discusses problems with these theories, proposes a causal-power theory that overcomes the problems, and reports empirical evidence favoring the new theory. Unlike earlier models, the new theory derives (a) the conditions under which covariation implies conjunctive causation (...) and (b) functions relating observable events to unobservable conjunctive causal strength. This psychological theory, which concerns simple cases involving 2 binary candidate causes and a binary effect, raises questions about normative statistics for testing causal hypotheses regarding categorical data resulting from discrete variables.

Drawing on macro-historical sociological theories, this book traces the development of intellectual property as a new type of legal property in the modern nation-state system. In its current form, intellectual property is considered part of an infrastructure of state power that incentivizes innovation, creativity, and scientific development, all engines of economic growth. To show how this infrastructure of power emerged, Laura Ford follows macro-historical social theorists, including Michael Mann and Max Weber, back to antiquity, revealing that legal instruments very (...) similar to modern intellectual property have existed for a long time and have also been deployed for similar purposes. Using comparative and historical evidence, this groundbreaking work reflects on the role of intellectual property in our contemporary political communities and societies; on the close relationship between law and religion; and on the extent to which law's obliging force depends on ancient, written traditions.

Examining the health of the population of the industrial world, the authors conclude that it is no healthier than it used to be, rather that diseases have been substituted, not eliminated. They suggest an alternative approach to health care which derives from a philosophy of nature.

This article draws on theoretical resources from economic sociology and sociology of law to intervene in economic debates about the relationship between intellectual property and industrialization. Utilizing historical evidence from the earliest period of American intellectual property law and from a formative company in the New England textile industry, I propose a social process of influence that connects intellectual property law to industrialization. I argue that, consistent with the findings of New Economic Sociology, social relationship structures and social capital are (...) the proximate influential force in industrialization. However, I also argue that transformative changes in those social relationship structures are rooted in the emergence of a particular type of political culture: what I call here, borrowing from Hannah Arendt and Frank Dobbin, a “Natal-Industrial Culture.” A Natal-Industrial Culture, as I propose it here, is a political culture in which collective hopes for the future are placed in new technologies and new cultural products, as means for achieving economic growth. Intellectual property law contributed to the emergence of this new type of political culture by holding out the promise of property, as a reward for the provision of new technologies or new cultural products. Because of the way that hope works on motivation—through cognitive pre-rehearsals of future attainment, which involve semantically-meaningful propositions and contribute to positive emotional experience—the promise of property provided a powerful stimulant to social capital formation. Working through the semantic resonances of property, intellectual property law contributed to a political culture in which invention and creativity were expected to secure a future of growth within the political community, both for particular members and for the political community, as a whole. By fostering a Natal-Industrial Culture, intellectual property law contributed to systematic invention and social capital-formation, leading, in turn, to the transformative changes in working and material provisioning that constitute industrialization.

Although the expression 'intellectual property' is widely used, it could be argued that the very idea of intellectual property is incoherent. After all, ideas are not like land, houses or clothing; surely they are not the sorts of things that can be owned? I shall examine two arguments - one ontological, one jurisprudential - that put pressure on the coherence of the idea of intellectual property, both leading to the conclusion that intellectual property rights are not genuine property rights, but (...) rights to monopolies. In setting up and responding to the first argument, I discuss the applicability of the type/ token distinction to intellectual property law; a distinction I also appeal to as a way of clarifying my response to the second argument.

PURPOSE: The purpose of this paper is to consider some of the philosophical and bioethical issues raised by the creation of the draft social values framework developed to facilitate data collection and country-specific presentations at the inaugural workshop on "Social values and health priority setting" held in February 2011. -/- DESIGN/METHODOLOGY/APPROACH: Conceptual analysis is used to analyse the term "social values", as employed in the framework, and its relationship to related ideas such as moral values. The structure of the framework (...) (process and content values) is considered in light of current debate in philosophy and bioethics about the political and moral aims served by these kinds of values, and the extent to which they are either suited to, or sufficient for, the policy context. -/- FINDINGS: There is much to be gained by engaging with the arguments presented in the philosophical literature in order to further refine the framework. The framework should remain neutral in respect of the importance of procedural values in different contexts and should be as inclusive as possible in respect of the principles it includes. Further development would be best served by taking a multidisciplinary approach. The framework could provide a valuable space in which future debates about procedural/substantive values can be considered. -/- ORIGINALITY/VALUE: The paper brings philosophical and bioethics perspectives to bear on a new framework proposed for the analysis of social values in health priority setting. It identifies how such a practical, policy-focused framework might be informed by engagement with deeper, and often unresolved, questions or principle around resource allocation in health. (shrink)

This article reports the results of an experiment involving 108 college students with varying backgrounds in biology. Subjects answered questions about the evolutionary history of sets of hominid and equine taxa. Each set of taxa was presented in one of three diagrammatic formats: a noncladogenic diagram found in a contemporary biology textbook or a cladogram in either the ladder or tree format. As predicted, the textbook diagrams, which contained linear components, were more likely than the cladogram formats to yield explanations (...) of speciation as an anagenic process, a common misconception among students. In contrast, the branching cladogram formats yielded more appropriate explanations concerning levels of ancestry than did the textbook diagrams. Although students with stronger backgrounds in biology did better than those with weaker biology backgrounds, they generally showed the same effects of diagrammatic format. Implications of these results for evolution education and for diagram design more generally are discussed. (shrink)

Three experiments, adopting an evolutionary biology perspective, investigated subjects’ inferences about living things. Subjects were told that different enzymes help regulate cell function in two taxa and asked which enzyme a third taxon most likely uses. Experiment 1 and its follow-up, with college students, used triads involving amphibians, reptiles, and mammals (reptiles and mammals are most closely related evolutionarily) and plants, fungi, and animals (fungi are more closely related to animals than to plants). Experiment 2, with 10th graders, also included (...) triads involving mammals, birds, and snakes/crocodilians (birds and snakes/crocodilians are most closely related). Some subjects received cladograms (hierarchical diagrams) depicting the evolutionary relationships among the taxa. The effect of providing cladograms depended on students’ background in biology. The results illuminate students’ misconceptions concerning common taxa and constraints on their willingness to override faulty knowledge when given appropriate evolutionary evidence. Implications for introducing tree thinking into biology curricula are discussed. (shrink)

As a tool we introduce -piecewise vector bundles on X and show that the category of piecewise vector bundles on X is equivalent to the category of syzygies of (...) finitely generated submodules of free modules. We give an explicit method to determine the Baur–Monk invariants of free modules in terms of pre-piecewise vector bundles. When R is a recursive real closed field this yields the decidability of the theory of free modules. Where it makes sense, we address the same questions for continuous definable functions in o-minimal expansions of a real closed field. From the free module case we are able to deduce generalisations of some results to arbitrary modules over the ring. We present a geometrically motivated quantifier elimination result down to the level of positive primitive formulae with a certain block decomposition of the matrix of coefficients. (shrink)

The authors investigated whether college students possess abstract rules concerning the applicability conditions for three spatial diagrams that are important tools for thinking—matrices, networks, and hierarchies. A total of 127 students were asked to select which type of diagram would be best for organising the information in each of several short scenarios. The scenarios were written using three different story contexts: (a) neutral, presenting a real-life situation but not cueing a particular representation; (b) abstract, presenting only variable names and relations; (...) and (c) incongruent, in which the context and informational structure cued different representations. The results indicated above-chance performance on the abstract scenarios, as well as comparable performance on the abstract and neutral context scenarios. In a follow-up study in which eight students thought out loud while selecting diagrams for the abstract scenarios, there were almost no references to concrete examples. The results of these studies suggest that students possess abstract rules concerning the applicability conditions for matrices, networks, and hierarchies. (shrink)

Among the factors necessary for the occurrence of some event, which of these are selectively highlighted in its explanation and labeled as causes — and which are explanatorily omitted, or relegated to the status of background conditions? Following J. S. Mill, most have thought that only a pragmatic answer to this question was possible. In this paper I suggest we understand this ‘causal selection problem’ in causal-explanatory terms, and propose that explanatory trade-offs between abstraction and stability can provide a principled (...) solution to it. After sketching that solution, it is applied to a few biological examples, including to a debate concerning the ‘causal democracy’ of organismal development, with an anti-democratic (though not a gene-centric) moral.

Whether in meta-analysis or single experiments, selecting results based on statistical significance leads to overestimated effect sizes, impeding falsification. We critique a quantitative synthesis that used significance to score and select previously published effects for situation awareness-performance associations. How much does selection using statistical significance quantitatively impact results in a meta-analytic context? We evaluate and compare results using significance-filtered effects versus analyses with all effects as-reported. Endsley reported high predictiveness scores and large positive mean correlations but used atypical methods: the (...) hypothesis was used to select papers and effects. Papers were assigned the maximum predictiveness scores if they contained at-least-one significant effect, yet most papers reported multiple effects, and the number of non-significant effects did not impact the score. Thus, the predictiveness score was rarely less than the maximum. In addition, only significant effects were included in Endsley’s quantitative synthesis. Filtering excluded half of all reported effects, with guaranteed minimum effect sizes based on sample size. Results for filtered compared to as-reported effects clearly diverged. Compared to the mean of as-reported effects, the filtered mean was overestimated by 56%. Furthermore, 92% of the as-reported effects were below the mean of filtered effects. We conclude that outcome-dependent selection of effects is circular, predetermining results and running contrary to the purpose of meta-analysis. Instead of using significance to score and filter effects, meta-analyses should follow established research practices. (shrink)

Inductive reasoning is fundamental to human cognition, yet it remains unclear how we develop this ability and what might influence our inductive choices. We created novel categories in which crucial factors such as domain and category structure were manipulated orthogonally. We trained 403 4–9-year-old children to categorise well-matched natural kind and artefact stimuli with either featural or relational category structure, followed by induction tasks. This wide age range allowed for the first full exploration of the developmental trajectory of inductive reasoning (...) in both domains. We found a gradual transition from perceptual to categorical induction with age. This pattern was stable across domains, but interestingly, children showed a category bias one year later for relational categories. We hypothesise that the ability to use category information in inductive reasoning develops gradually, but is delayed when children need to process and apply more complex category structures.

This paper reviews current trends in the development of agricultural biotechnology, including (1) the recent and potential biotechnology products and processes in the plant, animal and food sciences, and (2) the enormous increase in Federal and State government and industrial investments in biotechnology research. Next we analyze the impacts and possible consequences of agricultural biotechnology for public and private agricultural research and for the structure and nature of the food system in this country and around the world. We conclude with (...) a range of proposals for agricultural research policies. Among the possible consequences we discuss are: (1) a shift in disciplinary emphasis in the research community to molecular biology, (2) reduction of research on systems, ecology, and the social sciences, (3) increased concentration of research funds at a small number of institutions, (4) reduction of long-term research in the public sector, (5) increased collaboration between industry, government and universities with a restriction of scientific communication, and a potential for conflict of interest, favoritism and increased scientific misconduct, (6) a change of the primary goals and agenda of the public sector research community, and (7) increased concentration in the agribusiness sector and the industrialization of the food system. Our policy suggestions include: (1) maintaining and strengthening an independent public research and teaching system, (2) striking a balance between short-term proprietary biotechnology and long-term nonproprietary research, (3) maintaining an extension system that delivers biotechnology information and products to all potential users, (4) developing a regulatory system that adequately protects the public and provides clear guidelines to industry. (5) assisting developing nations to reap the benefits of the biotechnology revolution, and (6) establishing mechanisms to foster broad-based understanding of the social and ethical issues relating to agricultural biotechnology and to promote research on the social and ethical impacts.

Environmental ethicists have frequently criticized ancient Greek philosophy as anti-environmental for a view of philosophy that is counterproductive to environmental ethics and a view of the world that puts nature at the disposal of people. This provocative collection of original essays reexamines the views of nature and ecology found in the thought of Plato, Aristotle, the Stoics, and Plotinus. Recognizing that these thinkers were not confronted with the environmental degradation that threatens contemporary philosophers, the contributors to this book find that (...) the Greeks nevertheless provide an excellent foundation for a sound theory of environmentalism.

Lack of specificity around stakeholder identity remains a serious obstacle to the further development of stakeholder theory andits adoption in actual practice by business managers. Nowhere is this shortcoming more evident than in stakeholder theory’s treatment of the constituency known as “community.”In this paper we attempt to set forth what we call “the Problem of Community” as indicative of the definitional problems of stakeholdertheory. We then begin the process of gaining greater specificity around our notions of community and the role (...) of community in stakeholder theory and management. In doing so, we identify the emergence of two fairly new forms of community that we believe are particularly relevant to the stakeholder theorist and practicing manager. These two new variants of community—the virtual advocacy group and the community of practice—extend the notion of community in new directions, which have strikingly different implications for stakeholder theory and practice.

The New Social Disease is about how we personalize our computers and associated technologies while depersonalizing others and ourselves.

The purpose of this paper is to describe a way of teaching business ethics using the creative arts, especially literature and theater. By drawing on these disciplines for both method and texts, we can more easily make the connection to business as a fully human activity, concerned with how meaning is created. Students are encouraged to understand story-telling and narrative and how these tools lend insight into the daily life of businesspeople. The paper describes two main courses, Business Ethics Through (...) Literature and Leadership, Ethics and Theater, and the rationale for each. We begin by suggesting three main leverage points that the courses engender. We then rely on the words of students who have taken the courses for insights into what they learned. We then critically assess some of the principles that have informed course design over time. We conclude by suggesting that paying attention to the creative arts gives rise to a rather different approach to business ethics, one grounded in the pragmatist tradition in philosophy. (shrink)

Growing ties to private industry have prompted many to question the impartiality of academic bioethicists who receive financial support from for-profit corporations in exchange for ethics-related services and research. To the extent that corporate sponsors may view bioethics as little more than a way to strengthen public relations or avoid potential controversy, close ties to industry may pose serious threats to professional independence. New sources of support from private industry may also divert bioethicists from pursuing topics of greater social importance, (...) such as the needs of medically underserved communities. To inform ongoing debates about the financing of bioethics and its transparency to those concerned about potential sources of bias, we examined funding disclosures appearing in original research reports in major bioethics journals. Reviewing research published over a 15-year period, we found little evidence that for-profit corporations are influencing bioethics research directly. Instead, we found evidence that a great number of organizations, both public and private, support bioethics research. These findings suggest that worries about the cooption of bioethics research by a few interested stakeholders are greatly overstated and undersupported by available data. (shrink)
