ObjectivesTo describe reporting of informed consent in pragmatic trials, justifications for waivers of consent and reporting of alternative approaches to standard written consent. To identify factors associated with (1) not reporting and (2) not obtaining consent.MethodsSurvey of primary trial reports, published 2014–2019, identified using an electronic search filter for pragmatic trials implemented in MEDLINE, and registered in ClinicalTrials.gov.ResultsAmong 1988 trials, 132 (6.6%) did not include a statement about participant consent, 1691 (85.0%) reported consent had been obtained, 139 (7.0%) reported a (...) waiver and 26 (1.3%) reported consent for one aspect (eg, data collection) but a waiver for another (eg, intervention). Of the 165 trials reporting a waiver, 76 (46.1%) provided a justification. Few (53, 2.9%) explicitly reported use of alternative approaches to consent. In multivariable logistic regression analyses, lower journal impact factor (p=0.001) and cluster randomisation (p<0.0001) were significantly associated with not reporting on consent, while trial recency, cluster randomisation, higher-income country settings, health services research and explicit labelling as pragmatic were significantly associated with not obtaining consent (all p<0.0001).DiscussionNot obtaining consent seems to be increasing and is associated with the use of cluster randomisation and pragmatic aims, but neither cluster randomisation nor pragmatism are currently accepted justifications for waivers of consent. Rather than considering either standard written informed consent or waivers of consent, researchers and research ethics committees could consider alternative consent approaches that may facilitate the conduct of pragmatic trials while preserving patient autonomy and the public’s trust in research.

A new technique for proving realisability results is presented, and is illustrated in detail for the simple case of arithmetic minus induction. CL is a Gentzen formulation of classical logic. CPQ is CL minus the Cut Rule. The basic proof theory and model theory of CPQ and CL is developed. For the semantics presented CPQ is a paraconsistent logic, i.e. there are non-trivial CPQ models in which some sentences are both true and false. Two systems of arithmetic minus induction are (...) introduced, CL-A and CPQ-A based on CL and CPQ, respectively. The realisability theorem for CPQ-A is proved: It is shown constructively that to each theorem A of CPQ-A there is a formula A *, a so-called “realised disjunctive form of A ”, such that variables bound by essentially existential quantifiers in A * can be written as recursive functions of free variables and variables bound by essentially universal quantifiers. Realisability is then applied to prove the consistency of CL-A, making use of certain finite non-trivial inconsistent models of CPQ-A. (shrink)

Boarding school is a major educational option for many students (e.g., students living in remote areas, or whose parents are working interstate or overseas, etc.). This study explored the motivation, engagement, and achievement of boarding and day students who are educated in the same classrooms and receive the same syllabus and instruction from the same teachers (thus a powerful research design to enable unique comparisons). Among 2,803 students (boardingn= 481; dayn= 2,322) from 6 Australian high schools and controlling for background (...) attributes and personality, we found predominant parity between boarding and day students in their motivation, engagement, and achievement. We also found that classroom-average motivation, engagement, and achievement was not significantly affected by the number of boarders (relative to day students) in the classroom. In addition, the effects of boarding were generally not moderated by students’ background or personality attributes. We conclude that boarders have academic opportunities and outcomes that are comparable to their day student counterparts. Implications for students, teachers, and parents are discussed. (shrink)

The recent development and growth oforganic livestock farming and the relateddevelopment of national and internationalregulations has fueled discussions amongscientists and philosophers concerning theproper conceptualization of animal welfare.These discussions on livestock welfare inorganic farming draw on the conventionaldiscussions and disputes on animal welfare thatinvolve issues such as different definitions ofwelfare (clinical health, absence of suffering,sum of positive and negative experiences,etc.), the possibility for objective measuresof animal welfare, and the acceptable level ofwelfare. It seems clear that livestock welfareis a value-laden concept and (...) that animalwelfare science cannot be made independent ofquestions of values and ethics. The questioninvestigated here is whether those values thatunderpin organic farming, in particular, alsoaffect the interpretation of livestock welfare,and, if so, how. While some of the issuesraised in connection with organic farming arerelatively uncontroversial, others are not. Theintroduction of organic farming values seems tointroduce new criteria for what counts as goodanimal welfare, as well as a different ethicalbasis for making moral decisions on welfare.Organic farming embodies distinctive systemicor communitarian ethical ideas and the organicvalues are connected to a systemic conceptionof nature, of agriculture, of the farm, and ofthe animal. The new criteria of welfare arerelated to concepts such as naturalness,harmony, integrity, and care. While the organicvalues overlap with those involved in theconventional discussion of animal welfare, someof them suggest a need to set new prioritiesand to re-conceptualize animal welfare – forexample, with respect to ``naturalness,'''' inrelation to the possibilities for expression ofnatural behavior and in relation to animalintegrity as a concept for organismic harmony.The organic perspective also seems to suggest awider range of solutions to welfare problemsthan changes in farm routines or operations onthe animals. The systemic solutions include thechoice and reproduction of suitable breeds,changes in the farm structure, and changes inthe larger production and consumption system – including consumer perceptions andpreferences. But the organic values may alsocall for sacrifices of individual welfare in aconventional sense in order to advance welfarefrom the perspective of organic farming.Whether this is good or bad cannot be decidedwithout entering into an inquiry and discussionof the values and ethics involved.

We give a complete description of minimal groups infinitely definable in separably closed fields of finite degree of imperfection. In particular we answer positively the question of the existence of such a group with infinite transcendence degree (i.e., a minimal group with non thin generic).

The failure of the critics of corporate governance to agree on what should be done to improve the governance process can, in most cases, be traced to a different understanding of the role of corporate directors in that process. This article analyzes and contrasts the obligations of directors under two legal theories, the fictional person theory and the organic theory, of the corporation. A comparison of the director's obligations under each theory indicates that the organic theory provides a better basis (...) for assessing the performance of directors and initiating reform.Among the boards of directors of Fortune 500 companies, I estimate that 95% are not fully doing what they are legally, morally, and ethically supposed to do. And they couldn't, even if they wanted to. (shrink)

In response to rapidly rising health care costs in the United States, federal and state governments and private industry are instituting numerous and diverse cost-containment plans. As devices for coping with a scarcity of resources, such plans present serious challenges to physicians' traditional single-minded devotion to patient welfare. Those which contain costs by directly limiting medical options or by controlling physicians' daily clinical decisions can threaten the quality of medical care by allowing economic authorities to make essentially medical judgments. In (...) contrast, other plans coax compliance by arranging incentives, e.g., offering financial rewards for successful cost containment. While they allow for clinical freedom, these plans create conflicts between physicians' fiduciary obligations to their patients and the competing interests of the payers. Such conflicts arise as physicians try to work within governmental or corporate cost containment policies, and also as they attempt to streamline clinical efficiency. Throughout, issues of justice emerge as physicians seek to reconcile their own patients' claims upon limited common resources with others' equally legitimate claims. (shrink)

When I undertook to write an article for mathematical laymen on the mathematical infinite. I did not realize the depths of my own layness, I do now. Having refreshed my memory of the classics of infinity by re-reading among other things the famous papers of Cantor and Zermelo, and having struggled like a boa constrictor to swallow the latest papal bull on the human significance of the infinite, I am completely reduced to what Professor E. W. Hobson aptly and somewhat (...) indignantly calls Mathematical Nihilism. (shrink)

It has frequently been observed that the Prometheus Vinctus shows certain Sophoclean characteristics of rhythm. In order to vary the rhythm of his iambics and to avoid monotony, Sophocles often knits consecutive trimeters closely together by placing at the end of one line some word which looks forward to the next line, and so precludes the reader from stopping for the natural pause after the sixth foot. Sometimes he uses in this way subordinating words which introduce a dependent clause in (...) the next line ; sometimes proclitics or quasi-proclitics. (shrink)

'identity' includes a family of relations and is wrongly restricted to what satisfies leibniz's law: diachronic and strict identity are related since the criteria of the former are just the criteria of continuity of stages of the strictly identical continuant. A general account can be given in terms of the preservation of a weighted preponderance of properties of the stages. Puzzle cases arise because of contextual shifts in the weightings assigned; in the case of persons this is particularly clear because (...) of change of emphasis between mental and physical, Both of which classes of predicate are applicable.

Abela accepts Fine’s account of realism and instrumentalism, but thinks that we can reject the Natural Ontological Attitude by distinguishing the theoretical attempt to make sense of scientific practice from choosing the attitude we bring to the debate, or to science itself. But Abela’s attitudes are vulnerable to Fine’s criticisms of the philosophical positions. However, if we take attitude as contrastive and as full‐blooded enough to lead to different behaviour we can see a gap in Fine’s position. He cannot tell (...) us why it is science that he trusts. When we look more widely, the philosophical positions might be seen as ways of justifying that trust. (shrink)
