Lee and Schwarz interpret meta-analytic research and replication studies as providing evidence for the robustness of cleansing effects. We argue that the currently available evidence is unconvincing because publication bias and the opportunistic use of researcher degrees of freedom appear to have inflated meta-analytic effect size estimates, and preregistered replications failed to find any evidence of cleansing effects.

Background and aim With the increasing interest in lifestyle, health and consequences of unhealthy lifestyles for the healthcare system, a new kind of solidarity is gaining importance: lifestyle solidarity. While it might not seem fair to let other people pay for the costs arising from an unhealthy lifestyle, it does not seem fair either to punish people for their lifestyle. However, it is not clear how solidarity is assessed by people, when considering disease risks or lifestyle risks. The aim of (...) this study was to investigate the degree of solidarity with lifestyle as well as with other factors that are related to health outcomes—for example, old age—and the relation between this degree of solidarity and various characteristics. Methods This cross-sectional study is part of the Dutch longitudinal SMILE study. Data on the degree of solidarity with different lifestyles and old age, and the relation between the degree of solidarity and various demographic and other variables were obtained in a questionnaire survey. Results Solidarity with smokers and overweight people was moderate, as was solidarity with older people. Respondents were ambivalent about athletes. Respondents who were younger, male and highly educated, and those with a healthy lifestyle, a small social network, high quality of life and an internal locus of control, showed low solidarity. Conclusions Solidarity with an unhealthy lifestyle and old age is moderate and the degree of solidarity varies among the different subgroups. (shrink)

Theoretical arguments and empirical investigations indicate that a high proportion of published findings do not replicate and are likely false. The current position paper provides a broad perspective on scientific error, which may lead to replication failures. This broad perspective focuses on reform history and on opportunities for future reform. We organize our perspective along four main themes: institutional reform, methodological reform, statistical reform and publishing reform. For each theme, we illustrate potential errors by narrating the story of a fictional (...) researcher during the research cycle. We discuss future opportunities for reform. The resulting agenda provides a resource to usher in an era that is marked by a research culture that is less error-prone and a scientific publication landscape with fewer spurious findings.

This essay takes Arthur Danto’s end-of-art thesis as a case in point of a substantive philosophy of history. Such philosophy explains the direction that art has taken and why that direction could not have been different. Danto never scrutinized the philosophy of history that his end-of-art thesis presumes. I aim to do that by drawing a distinction between what I refer to as the common view of history and the philosophical view of history, and by arguing that we need the (...) latter if we want to properly assess the plausibility of the end-of-art thesis.

An important artistic topic of Italian Renaissance painting was the rendering of the human figure. As leading actors in a painted narrative, figures had to convince beholders of the reality of the matter depicted with appropriated attitudes and gestures. This article is about two ways of drawing or rather constructing the human figure artists developed to achieve this goal. The first was only an adaptation to an old method: because of the rather simple and coarse elements used, constructions often resulted (...) in faulty pictures and were for that matter often criticized. As this article will show, the second method involved a new and very successful drawing skill, which not just required a different kind of knowledge of visual forms but of procedures of moving the hand, too.

This comprehensive book covers the research, theory, policy and practice context of unusual reproduction using third parties. Olga Van den Akker details the psychological adaptation required to continuing changes in public opinion, advances in technologies and new legislations in surrogate motherhood and discusses their impact at an individual, societal and global level. She describes the competing interests and interactions between legal, organisational, personal, social, psychological and cultural issues in relation to biological and genetic surrogate and commissioning parenthood. This book (...) is intended for professionals, practitioners, academics and students interested in the complexities of unusual reproduction using multidisciplinary perspectives. (shrink)

The “exemplification theory of history” is proposed to account for the relationship between the past and historical narratives. The theory states that what belongs to the past according to some narrative does so in order to exemplify the historical thesis of that narrative. As such the theory explains how the past receives its meaning. This implies that the past has no intrinsic historical meaning itself. Moreover, it follows that historical narratives possess an autonomy of their own with regard to the (...) past. It is argued that the exemplification theory of history goes to the heart of narrativist philosophy of history. This claim is supported by the key arguments of three narrativist philosophers: Arthur Danto, Louis Mink and Frank Ankersmit. The distinction between the history of social individuals and the identification of such individuals turns out to be fundamental in this respect. The article concludes by distinguishing between a Platonic and an Aristotelian view on narrative and by explaining why we ought to prefer the former to the latter. (shrink)

ObjectiveInformed consent is a prerequisite for caesarean section, the commonest surgical procedure in low- and middle-income settings, but not always acquired to an appropriate extent. Exploring perceptions of health care workers may aid in improving clinical practice around informed consent. We aim to explore health workers’ beliefs and experiences related to principles and practice of informed consent.MethodsQualitative study conducted between January and June 2018 in a rural 150-bed mission hospital in Southern Malawi. Clinical observations, semi-structured interviews and a focus group (...) discussion were used to collect data. Participants were 22 clinical officers, nurse-midwives and midwifery students involved in maternity care. Data were analysed to identify themes and construct an analytical framework.ResultsDefinition and purpose of informed consent revolved around providing information, respecting women’s autonomy and achieving legal protection. Due to fear of blame and litigation, health workers preferred written consent. Written consent requires active participation by the consenting individual and was perceived to transfer liability to that person. A woman’s refusal to provide written informed consent may pose a dilemma for the health worker between doing good and respecting autonomy. To prevent such refusal, health workers said to only partially disclose surgical risks in order to minimize women's anxiety. Commonly perceived barriers to obtain a fully informed consent were labour pains, language barriers, women’s lack of education and their dependency on others to make decisions.ConclusionsHealth workers are familiar with the principles around informed consent and aware of its advantages, but fear of blame and litigation, partial disclosure of risks and barriers to communication hamper the process of obtaining informed consent. Findings can be used to develop interventions to improve the informed consent process. (shrink)

Prenatal expectations about what children will be like after birth may provide a context for how parents perceive their infant's actual temperament. We examined how these expectations and perceptions are associated and together predict early parenting behavior, with parenting behavior in turn predicting changes in temperament. Reports of 125 families about their expectations of their unborn child's temperament, their infant's temperament at 4 and 12 months post-partum, and their hostile, responsive, warm, and overprotective parenting were included. We also included data (...) from an independent sample of 168 mothers, with the same measures, except that mothers reported on Big Five personality traits at T1. Results indicated that in both samples, parents' expectations were positively associated with perceptions of infant temperament. Prenatal expectations and newborn temperament independently predicted parenting behavior, and maternal and paternal parenting in turn predicted infant temperament at T3, controlling for infant temperament at T2. Although overall findings indicated associations between a more difficult temperament and more negative/less positive parenting, significant combinations of specific traits and parenting behaviors were sample-specific—indicating that more research is necessary to draw a conclusion about specific links. Both maternal and paternal expectations about their unborn child's temperament appear to carry over into the postpartum reality and provide a context for shaping early interactions between caregivers and their children, which may further shape the developing temperament of the child.

The problem how to ascertain the truth about the past is as old as history itself. But until the work of Louis Mink, no clear distinction was made between questions concerning the truth of statements on the past and questions concerning the truth of historical narratives as a whole. A narrative, Mink argues, is not simply a conjunction of statements on the past. Therefore its truth cannot be a function of the truth of its individual statements. The problem of narrative (...) truth is according to him thus: although each statement asserting a relation between events is subject to confirmation and disconfirmation, the combination of interrelations as established by the historical narrative is not, even though such combination of interrelations represents a real combination in past reality and is claimed to be true. As if to further complicate the problem, Mink maintains that history shares its form with fiction. Three and a half decades after Mink formulated the problem of narrative truth, it has not been dealt with in a satisfying manner. Mink does not solve nor dissolve the problem he posed. That task is taken up in this essay. It will move us away from the vocabulary of literary theory towards a pragmatist account of narrative truth. (shrink)

At times we are told that our habitual way of thinking has become obsolete given the new challenge we are facing. Some of the conceptual resources at our disposal are no longer capable of addressing the challenge at hand. Therefore, they lose their appeal and are rejected. But only in contrast to these intellectual resources does the challenge appear as a challenge. So it seems that we are confronted with a paradox: we need the intellectual resources for their uselessness. For (...) a proper understanding of this paradox and to unravel it, I will distinguish between de dicto and de re readings of philosophical texts. This distinction is borrowed from the neo-pragmatist Robert Brandom. A de dicto reading of a text is concerned with what its author says. A de re reading of a text is concerned with what its author talks about. Unpacking this distinction allows us to evaluate the method of engaging with our stock of conceptual resources as part of scholarly argument. (shrink)

Formulating how biomimicry relates to nature has been crucial to ‘deepening’ its theory. Currently, an autopoietic model of nature dominates the literature. However, advances in the natural and human sciences have demonstrated that autopoiesis does not adequately explain complex, dynamic, responsive, and situated systems. This article draws on Beth Dempster’s (1998) characterisation of ecosystems as sympoietic, that is as homeorhetic, evolutionary, distributively controlled, unpredictable, and adaptive, and on Donna Jeanne Haraway’s (2016) critique that entities do not pre-exist their relationships. We (...) argue that using sympoietic processes of becoming as our model, measure, and mentor impacts biomimicry’s practice and relation to sustainability. Taking John Todd’s Living Machines as a case study, we explicate how sympoiesis unfurls autopoiesis. By integrating advances in the natural and human sciences into the philosophy of biomimicry, we address the limitations of the autopoietic model and provide a more comprehensive and adequate model of ‘nature.’.

Strengthening the abilities of smallholder farmers in developing countries, particularly women farmers, to produce for both home and the market is currently a development priority. In many contexts, ownership of assets is strongly gendered, reflecting existing gender norms and limiting women’s ability to invest in more profitable livelihood strategies such as market-oriented agriculture. Yet the intersection between women’s asset endowments and their ability to participate in and benefit from agricultural interventions receives minimal attention. This paper explores changes in gender relations (...) and women’s assets in four agricultural interventions that promoted high value agriculture with different degrees of market-orientation. Findings suggest that these dairy and horticulture projects can successfully involve women and increase production, income and the stock of household assets. In some cases, women were able to increase their control over production, income and assets; however in most cases men’s incomes increased more than women’s and the gender-asset gap did not decrease. Gender- and asset-based barriers to participation in projects as well as gender norms that limit women’s ability to accumulate and retain control over assets both contributed to the results. Comparing experiences across the four projects, especially where projects implemented adaptive measures to encourage gender-equitable outcomes, provides lessons for gender-responsive projects targeting existing and emerging value chains for high value products. Other targeted support to women farmers may also be needed to promote their acquisition of the physical assets required to expand production or enter other nodes of the value chain. (shrink)

In this article, an ethical analysis of an educational programme on renal replacement therapy options for patients and their social network is presented. The two main spearheads of this approach are: (1) offering an educational programme on all renal replacement therapy options ahead of treatment requirement and (2) a home-based approach involving the family and friends of the patient. Arguments are offered for the ethical justification of this approach by considering the viewpoint of the various stakeholders involved. Finally, reflecting on (...) these ethical considerations, essential conditions for carrying out such a programme are outlined. The goal is to develop an ethically justified and responsible educational programme. (shrink)

Let T be a complete o-minimal extension of the theory of real closed fields. We characterize the convex hulls of elementary substructures of models of T and show that the residue field of such a convex hull has a natural expansion to a model of T. We give a quantifier elimination relative to T for the theory of pairs (R, V) where $\mathscr{R} \models T$ and V ≠ R is the convex hull of an elementary substructure of R. We deduce (...) that the theory of such pairs is complete and weakly o-minimal. We also give a quantifier elimination relative to T for the theory of pairs (R, N) with R a model of T and N a proper elementary substructure that is Dedekind complete in R. We deduce that the theory of such "tame" pairs is complete. (shrink)

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

Leibniz’ Briefwechsel wird 1705/06 vor allem von den politischen und militärischen Großereignissen bestimmt, über deren Verlauf sich Leibniz informieren lässt und zu denen er eigene Einschätzungen an seine Korrespondenten weitergibt: Zum Spanischen Erbfolgekrieg, zum Nordischen Krieg und zu der Aussicht des Hauses Hannover auf die Thronfolge in England. Um letztere zu forcieren und eine Einladung der Kurfürstin Sophie nach England zu erzwingen, entwirft und publiziert er im Namen von Rowland Gwynne ein Pamphlet, das in London jedoch das genaue Gegenteil bewirkt (...) und im dortigen Parlament zum Skandal wird. Im Bereich der Philosophie greift Leibniz in die zwischen J. Le Clerc und P. Bayle geführte Diskussion um das Werk von R. Cudworth, The true intellectual system of the Universe, 1678, mit seiner Considération sur les principes de vie, et sur les natures plastiques, ein. Im August 1705 erreicht Leibniz’ Korrespondenz mit den China-Missionaren (J. Bouvet, J. de Fontaney, Ch. Le Gobien, A. Verjus, C. Visdelou) einen letzten Höhepunkt. Der Austausch mit dem Pariser Oratorianer J. Lelong widmet sich weiterhin nebeneinander Bibel-Bibliographie und dem Streit um die Anwendbarkeit des Differentialkalküls. (shrink)
