BackgroundIn specific situations it may be necessary to make an exception to the general rule of informed consent for scientific research with an intervention. Earlier reviews only described subsets of arguments for exceptions to waive consent.MethodsHere, we provide a more extensive literature review of possible exceptions to the rule of informed consent and the accompanying arguments based on literature from 1997 onwards, using both Pubmed and PsycINFO in our search strategy.ResultsWe identified three main categories of arguments for the acceptability of (...) a consent waiver: data validity and quality, major practical problems, and distress or confusion of participants. Approval by a medical ethical review board always needs to be obtained. Further, we provide examples of specific conditions under which consent waiving might be allowed, such as additional privacy protection measures.ConclusionsThe reasons legitimized by the authors of the papers in this overview can be used by researchers to form their own opinion about requesting an exception to the rule of informed consent for their own study. Importantly, rules and guidelines applicable in their country, institute and research field should be followed. Moreover, researchers should also take the conditions under which they feel an exception is legitimized under consideration. After discussions with relevant stakeholders, a formal request should be sent to an IRB. (shrink)

Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing together (...) researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

We examined participants' reading and recall of informed consent documents presented via paper or computer. Within each presentation medium, we presented the document as a continuous or paginated document to simulate common computer and paper presentation formats. Participants took slightly longer to read paginated and computer informed consent documents and recalled slightly more information from the paginated documents. We concluded that obtaining informed consent online is not substantially different than obtaining it via paper presentation. We also provide suggestions for improving (...) informed consent-in both face-to-face and online experiments. (shrink)

This paper presents an oral history of farming in the Southern Yangtze Valley in China, covering the period from pre-liberation to recent market liberalization. Using the stories and observations of 31 elderly residents of a small water town, the paper describes the hard labor of traditional farming practices and the acquiescence of many when, post-liberation, they could leave farming for better-paid factory work. However, in a departure from conventional analyses, these oral histories suggest that the co-dependency culture of traditional farming (...) has broken down, and farmers are unwilling to return to the land and continue farming. The changes in knowledge cultures of local farmers in recent decades are not likely to lead to pathways to working with incoming modern “outsider farmers,” nor able to be blended with potential new “urbanite” knowledges of those who might wish to increase organic farming. The current knowledge cultures of these farmers has shifted as needed to the optimization of family unit needs, naturally leading them to urbanization and the relinquishing of their ties to the land. For cultural rather than economic reasons, these farmers see themselves as the last peasant farmers of Tianshanzhuang. (shrink)

The Patient Self-Determination Act (PSDA) requires hospitals to ask patients upon admission whether they have an advance directive. Although the PSDA has received extensive criticism, little attention has been paid to the cost of the law, either during its legislative course or following its implementation. Nonetheless, several tangible and intangible costs are associated with the PSDA. Such costs may be incurred by different parties. This paper examines the costs and benefits of the PSDA and illustrates the extent of some of (...) its tangible costs. The incremental start-up cost for one institution's response to the PSDA is estimated to be $49,304 ($1.31 per admission) and the total implementation cost of the program to be $114,528. In addition, the national incremental start-up cost for hospitals to implement the PSDA is estimated to be between $43,625,114 and $101,569,922. Finally, the potential implications of the PSDA for future governmental health care ethics regulation are discussed. (shrink)

This paper concludes a special feature of Sustainability Science that explores a broad range of social value theoretical traditions, such as religious studies, social psychology, indigenous knowledge, economics, sociology, and philosophy. We introduce a novel transdisciplinary conceptual framework that revolves around concepts of 'lenses' and 'tensions' to help navigate value diversity. First, we consider the notion of lenses: perspectives on value and valuation along diverse dimensions that describe what values focus on, how their sociality is envisioned, and what epistemic and (...) procedural assumptions are made. We characterise fourteen of such dimensions. This provides a foundation for exploration of seven areas of tension, between: (1) the values of individuals vs collectives; (2) values as discrete and held vs embedded and constructed; (3) value as static or changeable; (4) valuation as descriptive vs normative and transformative; (5) social vs relational values; (6) different rationalities and their relation to value integration; (7) degrees of acknowledgment of the role of power in navigating value conflicts. In doing so, we embrace the 'mess' of diversity, yet also provide a framework to organise this mess and support and encourage active transdisciplinary collaboration. We identify key research areas where such collaborations can be harnessed for sustainability transformation. Here it is crucial to understand how certain social value lenses are privileged over others and build capacity in decision-making for understanding and drawing on multiple value, epistemic and procedural lenses.

Through the ability to preview the future , people can anticipate how best to think, feel and act in just about any setting. But exactly what factors determine the contents of prospection? Extending research on action identification and temporal construal, here we explored how action goals and temporal distance modulate the characteristics of future previews. Participants were required to imagine travelling to Egypt to climb or photograph a pyramid. Afterwards, to probe the contents of prospection, participants provided a sketch of (...) their imaginary experience. Results elucidated the impact of goal type and temporal distance on mental imagery. While a climbing goal prompted participants to draw a larger pyramid in the near than distant future, a photographic goal influenced only the compositional complexity of the sketches. These findings reveal how action goals and temporal distance shape the contents of future simulations. (shrink)

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

We prove that the set of properties describable by a uniform sequence of first-order sentences using at most k + 1 distinct variables is exactly equal to the set of properties checkable by a Turing machine in DSPACE[n k ] (where n is the size of the universe). This set is also equal to the set of properties describable using an iterative definition for a finite set of relations of arity k. This is a refinement of the theorem PSPACE = (...) VAR[O[1]] [8]. We suggest some directions for exploiting this result to derive trade-offs between the number of variables and the quantifier depth in descriptive complexity. (shrink)

The naive anti-realist holds the following principle: (◊K) All truths are knowable. This unrestricted generalization (◊K), as is now well known, falls prey to Fitch’s Paradox (Fitch 1963: 38, Theorem 1). It can be used as the only suspect principle, alongside others that cannot be impugned, to prove quite generally, and constructively, that the set {p, ¬Kp} is inconsistent (Tennant 1997: 261). From this it would follow, intuitionistically, that any proposition that is never actually known to be true (by anyone, (...) at any time) is false; and it would follow, classically, that every truth is known (by someone, at some time).

It became customary in the eighteenth century to praise Longinus in ways that mimicked one of his own favorite turns of thought—to identify enthusiastically two elements that would more commonly be thought of as quite distinct. To say, with Boileau and Pope, that Longinus “is himself the great Sublime he draws,” or to profess to doubt, as Gibbon did, “which is the most sublime, Homer’s Battle of the Gods or Longinus’ apostrophe…upon it,” is knowingly to override certain conventional lines of (...) demarcation—between writers and their subject matter, between text and interpretation—very much in the manner of Longinus overriding the distinction between Homer and his heroes, between sublime language and its author , or between sublime poet and his audience .1 Longinus’ admirers, struck by the force of the treatise, are usually willing to release him from the strictures of theoretical discourse and allow him the license of a poet; they are likely to appreciate his transgressions of conventional limits without ever calling them into question. It has been left to more skeptical readers, wary of Longinus’ “transports,” to draw attention to his odd movements of thought: W. K. Wimsatt, for example, is unsympathetic but acute when he accuses Longinus of “sliding” from one theoretical distinction to another, a slide “which seems to harbor a certain duplicity and invalidity.”2 Wimsatt is right: something one might want to call a “slide” is observable again and again in the treatise, and not merely from one theoretical distinction to another. One finds in the treatise a rhetorician’s argument conducted with great intelligence and energy, but one also discovers that it is remarkably easy to lose one’s way, to forget which rhetorical topic is under consideration at a particular point, to find oneself attending to a quotation, a fragment of analysis, a metaphor—some interestingly resonant bit of language that draws one into quite another system of relationships. I want to attempt to follow that movement here, to hold it in mind and to question its implications. I will look closely at a number of passages in which Longinus interweaves language of his own with that of the authors he admires—for it is here, out of the play of text with quotation and of quotations with one another, that the most interesting meanings as well as the peculiar power of the treatise are generated.1. ‘Longinus’ On Sublimity, trans.

Grube’s Longinus On Great Writing , and more particularly to the ample and intelligent introduction and notes accompanying Russell’s edition of the Greek text, ‘Longinus’ On the Sublime .2. W. K.

AGM-theory, named after its founders Carlos Alchourrón, Peter Gärdenfors and David Makinson, is the leading contemporary paradigm in the theory of belief-revision. The theory is reformulated here so as to deal with the central relational notions 'J is a contraction of K with respect to A' and 'J is a revision of K with respect to A'. The new theory is based on a principal-case analysis of the domains of definition of the three main kinds of theory-change (expansion, contraction and (...) revision). The new theory is stated by means of introduction and elimination rules for the relational notions. In this new setting one can re-examine the relationship between contraction and revision, using the appropriate versions of the so-called Levi and Harper identities. Among the positive results are the following. One can derive the extensionality of contraction and revision, rather than merely postulating it. Moreover, one can demonstrate the existence of revision-functions satisfying a principle of monotonicity. The full set of AGM-postulates for revision-functions allow for completely bizarre revisions. This motivates a Principle of Minimal Bloating, which needs to be stated as a separate postulate for revision. Moreover, contractions obtained in the usual way from the bizarre revisions, by using the Harper identity, satisfy Recovery. This provides a new reason (in addition to several others already adduced in the literature) for thinking that the contraction postulate of Recovery fails to capture the Principle of Minimal Mutilation. So the search is still on for a proper explication of the notion of minimal mutilation, to do service in both the theory of contraction and the theory of revision. The new relational formulation of AGM-theory, based on principal-case analysis, shares with the original, functional form of AGM-theory the idealizing assumption that the belief-sets of rational agents are to be modelled as consistent, logically closed sets of sentences. The upshot of the results presented here is that the new relational theory does a better job of making important matters clear than does the original functional theory. A new setting has been provided within which one can profitably address two pressing questions for A GM-theory: (1) how is the notion of minimal mutilation (by both contractions and revisions) best analyzed? and (2) how is one to rule out unnecessary bloating by revisions?

Colours are not the sorts of thing that are amendable to traditional forms of scientific explanation. To think otherwise is to mistake their ontology and ignore their normativity. The acquisition and use of colour categories is constrained by the logic of colour grammars.

We look for a converse to a result from [N. Thapen, A model-theoretic characterization of the weak pigeonhole principle, Annals of Pure and Applied Logic 118 175–195] that if the weak pigeonhole principle fails in a model K of bounded arithmetic, then there is an end-extension of K interpretable inside K. We show that if a model J of an induction-free theory of arithmetic is interpretable inside K, then either J is isomorphic to an initial segment of K , or (...) K is isomorphic to an initial segment of J and in this case the weak pigeonhole principle fails in K. This result is formulated in terms of a theory of bounded arithmetic with a greatest element. We go on to consider structures defined by oracles, and use the probabilistic witnessing theorem for to give a general criterion for what can be proved about these using the weak pigeonhole principle. We also show that the injective WPHP is not provable in this theory in the relativized case. (shrink)

Values-based medicine derives from an approach first introduced into the philosophy of psychiatry, which aims to demonstrate that the reality of mental illness is not inconsistent with the scientific status of medicine. Associated primarily with the work of K.W.M. Fulford, the argument is that practitioners need to be ethical anti-descriptivists if they are to avoid the authoritarianism of evidence-based medicine, which overlooks the fact that genuine value conflicts can arise during all clinical encounters, and that psychiatry is just the most (...) explicit area in which these occur. This paper takes a philosophically therapeutic line and argues that, by reducing values to the status of preferences, antidescriptivism undermines the value of 'value' and leaves the practitioner with a reduced ability to discern and negotiate genuine conflicts of value. The conclusion is that patients should be respected, not as instantiations of preferences but as valuers ; and that this requires practitioners to become more cosmopolitan and sympathetic, not more theoretically sophisticated.

We give a new characterization of the strict $$\forall {\Sigma^b_j}$$ sentences provable using $${\Sigma^b_k}$$ induction, for 1 ≤ j ≤ k. As a small application we show that, in a certain sense, Buss’s witnessing theorem for strict $${\Sigma^b_k}$$ formulas already holds over the relatively weak theory PV. We exhibit a combinatorial principle with the property that a lower bound for it in constant-depth Frege would imply that the narrow CNFs with short depth j Frege refutations form a strict hierarchy with (...) j, and hence that the relativized bounded arithmetic hierarchy can be separated by a family of $$\forall {\Sigma^b_1}$$ sentences.

Excerpt from An Etienne Gilson Tribute: Presented by His North American Students With a Response by Etienne Gilson The statement of these basic positions does not, of course, sweep away the special difficulties of predicating science or scientific of God. And these difficulties we ought now to gather together from St. Thomas' various Statements of them. There is the argument, for example, that science shares the lot of all intellectual k'nowledges in the accidentality of its being; whereas God is Without (...) accidents. Moreover, since science is the fruit of a certain process from principles to conclusions,6 it necessarily signifies something caused.

This book challenges the view that bad beliefs - beliefs that blatantly conflict with easily available evidence - can largely be explained by widespread irrationality, instead arguing that ordinary people are rational agents whose beliefs are the result of their rational response to the evidence they're presented with.
