BackgroundReducing the number of animals used in experiments has become a priority for the governments of many countries. For these reductions to occur, animal-free alternatives must be made more available and, crucially, must be embraced by researchers.MethodsWe conducted an international online survey for academics in the field of animal science (N = 367) to explore researchers’ attitudes towards the implementation of animal-free innovations. Through this survey, we address three key questions. The first question is whether scientists who use animals in (...) their research consider governmental goals for animal-free innovations achievable and whether they would support such goals. Secondly, responders were asked to rank the importance of ten roadblocks that could hamper the implementation of animal-free innovations. Finally, responders were asked whether they would migrate (either themselves or their research) if increased animal research regulations in their country of residence restricted their research.ResultsWhile nearly half (40%) of the responders support governmental goals, the majority (71%) of researchers did not consider such goals achievable in their field within the near future. In terms of roadblocks for implementation of animal-free methods, ~ 80% of the responders considered ‘reliability’ as important, making it the most highly ranked roadblock. However, all other roadblocks were reported by most responders as somewhat important, suggesting that they must also be considered when addressing animal-free innovations. Importantly, a majority reported that they would consider migration to another country in response to a restrictive animal research policy. Thus, governments must consider the risk of researchers migrating to other institutes, states or countries, leading to a ‘brain-drain’ if policies are too strict or suitable animal-free alternatives are not available.ConclusionOur findings suggest that development and implementation of animal-free innovations are hampered by multiple factors. We outline three pillars concerning education, governmental influence and data sharing, the implementation of which may help to overcome these roadblocks to animal-free innovations. (shrink)

This article introduces a new hybrid intake procedure developed for posttraumatic stress disorder (PTSD) screening, which combines an automated textual assessment of respondents’ self-narratives and item-based measures that are administered consequently. Text mining technique and item response modeling were used to analyze long constructed response (i.e., self-narratives) and responses to standardized questionnaires (i.e., multiple choices), respectively. The whole procedure is combined in a Bayesian framework where the textual assessment functions as prior information for the estimation of the PTSD latent trait. (...) The purpose of this study is twofold: first, to investigate whether the combination model of textual analysis and item-based scaling could enhance the classification accuracy of PTSD, and second, to examine whether the standard error of estimates could be reduced through the use of the narrative as a sort of routing test. With the sample at hand, the combination model resulted in a reduction in the misclassification rate, as well as a decrease of standard error of latent trait estimation. These findings highlight the benefits of combining textual assessment and item-based measures in a psychiatric screening process. We conclude that the hybrid test design is a promising approach to increase test efficiency and is expected to be applicable in a broader scope of educational and psychological measurement in the future.

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)

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.

Meta-theories, base-theories and theories of practice in Pratical Theology The problem of meta-theories and base-theories, their interaction and the influence of each on the scientific process, have widely been debated in practical theology. In South Africa two meta-theories namely the system- theory together with the theory that social science is busy with the study of actions, are having the greater deal of attention. The purpose of this article is to point out the fact that an early and absolute choice of (...) particular meta-theories, restricts the work of practical theology because it will influence your base-theories, and can weaken the theological content of practical theology. An attempt is made to offer a model by which the interaction between, meta-theories, base-theories and theories of practice can he understood and which can also help the theologian, busy with practical theology, to steer clear of problems and understand the meta- influences in his own scientific work.

Libraries provide access to large amounts of library metadata. Unfortunately, many libraries only offer textual interfaces for searching and browsing their holdings. Visualizations provide simpler, faster, and more efficient ways to navigate, search and study large quantities of metadata. This paper presents GlamMap, a visualization tool that displays library metadata on an interactive, computer-generated geographic map. We provide detailed discussion of how GlamMap benefits the work of librarians and researchers. We show how geographic representations help librarians to perform tasks such (...) as collection assessment and how geographic information helps researchers to identify important scientific resources.

How can new drug lead suggestions beinferred from neurophysiological models? This paperaddresses this question based on a case study ofresearch into Parkinson''s disease at the GroningenUniversity Department of Pharmacy. It is argued thatneurophysiological box-and-arrow models can beunderstood as qualitative differential equationmodels. An inference task is defined to helpunderstand and possibly aid the discovery andexplanation of new drug lead suggestions.

Such sources are kept in the Algemeen Rijksarchief, in the Parliament, various ministerial departments, the Navorsings- en Studiecentrum voor de Geschiedenis van de Tweede Wereldoorlog, study centres of the major political parties, a number of non-governmental organizations as well as the private archives of a number of politicians.

BackgroundObtaining informed consent for intravenous thrombolysis in acute ischemic stroke can be challenging, and little is known about if and how the informed consent procedure is performed by neurologists in clinical practice. This study examines the procedure of informed consent for intravenous thrombolysis in acute ischemic stroke in high-volume stroke centers in the Netherlands.MethodsIn four high volume stroke centers, neurology residents and attending neurologists received an online questionnaire concerning informed consent for thrombolysis with tissue-type plasminogen activator (tPA). The respondents were (...) asked to report their usual informed consent practice for tPA treatment and their considerations on whether informed consent should be obtained.ResultsFrom the 203 invited clinicians, 50% (n = 101) completed the questionnaire. One-third of the neurology residents (n = 21) and 21% of the neurologists (n = 8) reported that they always obtain informed consent for tPA treatment. If a patient is not capable of providing informed consent, 30% of the residents (n = 19) reported that they start tPA treatment without informed consent. In these circumstances, 53% of the neurologists (n = 20) reported that the resident under their supervision would start tPA treatment without informed consent. Most neurologists (n = 21; 55%) and neurology residents (n = 45; 72%) obtained informed consent within one minute. None of the respondents used more than five minutes for informed consent. Important themes regarding obtaining informed consent for treatment were patients’ capacity, and medical, ethical and legal considerations.ConclusionThe current practice of informed consent for thrombolysis in acute ischemic stroke varies among neurologists and neurology residents. If informed consent is obtained, most clinicians stated to obtain informed consent within one minute. In the future, a shortened information provision process may be applied, making a shift from informed consent to informed refusal, while still considering the patient’s capacity, stroke severity, and possible treatment delays.

This paper explores structuralism as a way to model theories from scientific practice. As a case study I analyzed a theory about the dynamics of the basal ganglia, a part of the brain that is involved in Parkinson's disease. After introducing the case study I explore how to structurally represent qualitative assumptions about disease, intervention and dynamical systems in general. I further explicate the structure of the basal ganglia theory in detail, how it explains Parkinson's disease and how it implies (...) treatments. I close with a consideration of how a structuralist representation could be useful in practice to explore and develop theories with the aid of a computer. (shrink)

Objectives: Efficient procedures for obtaining informed (proxy) consent may contribute to high influenza vaccination rates in nursing homes. Yet are such procedures justified? This study’s objective was to gain insight in informed consent policies in Dutch nursing homes; to assess how these may affect influenza vaccination rates and to answer the question whether deviating from standard informed consent procedures could be morally justified. Design: A survey among nursing home physicians. Setting & Participants: We sent a questionnaire to all (356) nursing (...) homes in the Netherlands, to be completed by one of the physicians. Results: We received 245 completed questionnaires. As 21 institutions appeared to be closed or merged into other institutions, the response was 73.1% (245/335). Of all respondents 81.9% reported a vaccination rate above 80%. Almost 50% reported a vaccination rate above 90%. Most respondents considered herd immunity to be an important consideration for institutional policy. Freedom of choice for residents was considered important by almost all. Nevertheless, 106 out of 245 respondents follow a tacit consent procedure, according to which vaccination will be administered unless the resident or her proxy refuses. These institutions show significantly higher vaccination rates (p < 0.03). Conclusions: In our discussion we focus on the question whether tacit consent procedures can be morally justifiable. Such procedures assume that vaccination is good for residents either as individuals or as a group. Even though this assumption may be true for most residents, there are good reasons for preferring express consent procedures. (shrink)

A theory of the joint measurement of quantum mechanical observables is generalized in order to make it applicable to the measurement of the local observables of field theory. Subsequently, the property of local commutativity, which is usually introduced as a postulate, is derived by means of the theory of measurement from a requirement of mutual nondisturbance, which, for local observables performed at a spacelike distance from each other, is interpreted as a requirement of macrocausality. Alternative attempts at establishing a deductive (...) relationship between relativistic causality and local commutativity are reviewed, but found wanting, either because of the assumption of an unwarranted objectivity of the object system (algebraic approach) or because of the use of a projection postulate (operational approach). Finally, the quantum mechanical nonobjectivity is related to certain features of nonlocality which are present in the formalism of quantum mechanics. (shrink)

OBJECTIVES: Cognitive and sensory difficulties frequently jeopardize informed consent of frail elderly patients This study is the first to test whether preliminary research experience could enhance geriatric patients' capacity to consent. DESIGN/SETTING: A step-wise consent procedure was introduced in a study on fluid balance in geriatric patients. Eligible patients providing verbal consent participated in a try-out of a week, during which bioelectrical impedance and weight measurements were performed daily. Afterwards, written informed consent was requested. Comprehension, risk and inconvenience scores (ranges: (...) 0-10) were obtained before and after the try-out by asking ten questions about the study's essentials and by asking for a risk and inconvenience assessment on a ten-points rating scale. SUBJECTS AND RESULTS: Seventy of the 78 eligible subjects started the try-out and 53 (68%) provided written consent. The comprehension score increased from 5.0 (+/- 2.3) to 7.0 (+/- 1.9) following the try-out (P < 0.001). The number of subjects capable of weighing risks and inconveniences increased from 32 to 48 (P < 0.001). CONCLUSIONS: Research experience improved the capacity to consent, still enabling an acceptable participation rate. Therefore, experienced consent seems a promising tool to optimize informed consent in frail elderly subjects. (shrink)

Patient-reported outcomes are frequently used for medical decision making, at the levels of both individual patient care and healthcare policy. Evidence increasingly shows that PROs may be influenced by patients’ response shifts and dispositions. We identify how response shifts and dispositions may influence medical decisions on both the levels of individual patient care and health policy. We provide examples of these influences and analyse the consequences from the perspectives of ethical principles and theories of just distribution. If influences of response (...) shift and disposition on PROs and consequently medical decision making are not considered, patients may not receive optimal treatment and health insurance packages may include treatments that are not the most effective or cost-effective. We call on healthcare practitioners, researchers, policy makers, health insurers, and other stakeholders to critically reflect on why and how such patient reports are used. (shrink)

This article focuses on maternal-fetal surgery (MFS) and on the concept of clinical equipoise that is a widely accepted requirement for conducting randomized controlled trials (RCT). There are at least three reasons why equipoise is unsuitable for MFS. First, the concept is based on a misconception about the nature of clinical research and the status of research subjects. Second, given that it is not clear who the research subject/s in MFS is/are, if clinical equipoise is to be used as a (...) criterion to test the ethical appropriateness of RCT, its meaning should be unambiguous. Third, because of the multidisciplinary character of MFS, it is not clear who should be in equipoise. As a result, we lack an adequate criterion for the ethical review of MFS protocols. In our account, which is based on Chervenak and McCullough's seminal work in the field of obstetric ethics, equipoise is abandoned. and RCT involving MFS can be ethically initiated when a multidisciplinary ethics review board (ERB), having an evidence-based assessment of the risks involved, is convinced that the value of answering the research hypothesis, for the sake of the health interests of future pregnant women carrying fetuses with certain congenital birth defects, justifies the actual risks research participants might suffer within a set limit of low/manageable.

Chervenak and McCullough, authors of the most acknowledged ethical framework for maternal–fetal surgery, rely on the ‘ethical–obstetrical’ concept of the fetus as a patient in order to determine what is morally owed to fetuses by both physicians and the women who gestate them in the context of prenatal surgery. In this article, we reconstruct the argumentative structure of their framework and present an internal criticism. First, we analyse the justificatory arguments put forward by the authors regarding the moral status of (...) the fetus qua patient. Second, we discuss the internal coherence and consistency of the moral obligations those authors derive from that concept. We claim that some of the dilemmas their approach is purported to avoid, such as the debate about the independent moral status of the fetus, and the foundation of the moral obligations of pregnant women (towards the fetuses they gestate) are not, all things considered, avoided. Chervenak and McCullough construct the obligations of physicians as obligations towards entities with equal moral status. But, at the same time, they assume that the woman has an independent moral status while the moral status of the fetus is dependent on the decision of the woman to present it to a physician for care. According to the logic of their own argumentation, Chervenak and McCullough implicitly admit a different moral status of the woman and the fetus, which will lead to different ascription of duties of the physician than those they ascribed.

PurposeThe purpose of this study is to describe the implementation and outcomes of an Eye Movement and Desensitization Reprocessing treatment-program for women with posttraumatic stress disorder after childbirth.MethodsA prospective cohort-study with pre- and post-measurements was carried out in the setting of an academic hospital in the Netherland. Included were women who gave birth to a living child at least 4 weeks ago, with a diagnosis of PTSD, or severe symptoms of PTSD combined with another psychiatric diagnosis. All received up to (...) 8 sessions of EMDR-therapy. The posttraumatic stress disorder Checklist for DSM-5 was administered before and after treatment. Trauma history was assessed before treatment with the Life Events Checklist for the DSM-5, the Childhood Trauma Questionnaire and the Childbirth Perception Scale. Descriptive statistics were used.ResultsForty-four women were referred, 26 met the inclusion criteria. After treatment, none of the women met the criteria for diagnosis of PTSD after on average 5 weekly sessions of EMDR- therapy. These outcomes are promising, as they were achieved in women with relatively high levels of psychiatric comorbidity and high rates of previous mental health treatment.ConclusionImplementing an EMDR-treatment program for women with PTSD after childbirth in the setting of an academic hospital is feasible and effective. Key factors for success include a close collaboration between the relevant hospital departments and a thorough case conceptualization addressing the etiology of the PTSD. (shrink)

Background A team-based approach has been advocated for advance care planning in nursing homes. While nurses are often put forward to take the lead, it is not clear to what extent other professions could be involved as well. Objectives To examine to what extent engagement in advance care planning practices, knowledge and self-efficacy differ between nurses, care assistants and allied care staff in nursing homes. Design Survey study. Participants/setting The study involved a purposive sample of 14 nursing homes in Flanders, (...) Belgium. Nurses, care assistants and allied care staff completed a survey. Ethical considerations The study was approved by the University Hospital of Brussels, as part of a cluster randomized controlled trial. Results One hundred ninety-six nurses, 319 care assistants and 169 allied staff participated. After adjusting for confounders, nurses were significantly more likely than care assistants to have carried out advance care planning conversations and documented advance care planning ; differences not found between allied staff and care assistants. Advance care planning knowledge total scores differed significantly, with nurses ; 95% confidence interval 0.08–0.17; p < 0.001) and allied staff scoring higher than care assistants. We found no significant differences regarding self-efficacy. Discussion While nursing home nurses conducted more advance care planning conversations and documentation than allied care staff and care assistants, these two professional groups may be a valuable support to nurses in conducting advance care planning, if provided with additional training. Conclusions Allied care staff and care assistants, if trained appropriately, can be involved more strongly in advance care planning to enhance relational and individual autonomy of nursing home residents, alongside nurses. Future research to improve and implement advance care planning should consider this finding at the intervention development stage. (shrink)

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)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dekoloniales Philosophieren. Versuch über philosophische Verantwortung und Kritik im Horizont der europäischen Expansion by Rolf ElberfeldAdy Van den Stock (bio)Dekoloniales Philosophieren. Versuch über philosophische Verantwortung und Kritik im Horizont der europäischen Expansion. By Rolf Elberfeld. Hildesheim: Universitätsverlag Hildesheim; Hildesheim, Zürich, New York: Georg Olms Verlag, 2021. Pp. 244. Paperback €19.80, isbn 978-3-487-16042-9. Calls for the decolonization of knowledge have come to resound far beyond the walls of institutes (...) of higher education in recent years and are tied up with a much broader quest for social justice in various domains of social life. If to decolonize presupposes taking a stance in relation to the history and ongoing effects of colonialism in different societies across the globe, decolonizing the academic discipline of philosophy would first of all involve dragging it out of the safety of its conventional epistemic and institutional confines in order to face up to past and present realities usually considered to be tangential to its primary concerns and interests. In taking its cue from the historical entwinement of (modern Western) philosophy with colonial practices and experiences of colonization, Rolf Elberfeld's Decolonial Philosophizing: Toward Philosophical Responsibility and Critique in the Horizon of the European Expansion approaches this "negative history" (Negativgeschichte, p. 14) as belying the categorical separation between genesis and validity, which the author sees as being at the heart of the analytical tradition dominating academic philosophy in Germany and beyond (pp. 11, 19–20). For Elberfeld, philosophy in general has tended to "immunize" itself against its own entanglement (Verstrickung) with the historical reality of colonialism. In his view, a prevailing disavowal of the latter's relevance for philosophical practice has made it hard, if not impossible, to come to terms with phenomena of exclusion, discrimination, and marginalization in the history of philosophy and has prevented us from subjecting these "blind spots" to a thoroughly reflexive critique (pp. 11–18). As a result, the kind of justifiable anger expressed by Aimé Césaire in his Discourse on Colonialism (1950) when he writes that colonialism has effectively made European civilization "untenable" (quoted on p. 13) cannot be taken as seriously as it deserves, insofar as it is seen as merely being of "historical" (or worse: "anecdotal") instead of properly "philosophical" relevance. By contrast, in Elberfeld's view, the historical entanglement of philosophy and colonialism is not merely, to paraphrase Adorno, a shameful "splinter in our eye" with the [End Page 1] somewhat limited function of provoking moral outrage or a blanket condemnation of all things "Western" (see pp. 14, 40, 83), but can also serve as a "magnifying glass"1 allowing philosophers to come to a better understanding of the history of their own discipline and thus break new ground. He argues that it is only by taking Césaire's pronouncement seriously, that is to say, by first of all patiently listening to (pp. 12, 219, 221) and thinking through such indictments, that the (European-all-too-European?) project of the Enlightenment can be salvaged and carried further. For Elberfeld, "Enlightenment" (Aufklärung) must now both recognize and arise from within its historically entangled (verstrickungsgeschichtliche) nature. Instead of unilaterally declaring its independence from history, it must now become, as the delightful but quasi-untranslatable German expression goes, verstrickungsgeschichtliche Aufklärung (pp. 9, 17, 209–218). If, then, the project of "decolonial philosophizing" is more than mere virtue-signaling, this is because it allows us to "know better," that is to say, enhances our capacity for assuming "epistemic responsibility."2Despite the complexity and contentious nature of its subject matter, Rolf Elberfeld has succeeded in producing an eminently readable and highly nuanced book which can serve as a good introduction to some of the most important topics and problems relevant to what has been dubbed the "decolonial turn" in philosophy and the humanities more broadly speaking. In twelve relatively brief chapters, the reader is taken on a journey across several continents and cultures through a period roughly spanning the symbolic date of 1492—which the author, following Enrique Dussel, sees as marking the birth of "modernity" (pp. 25–26)—up to the present day. Reflecting the basic... (shrink)

The impact of the Internet on democracy is a widely discussed subject. Many writers view the Internet, potentially at least, as a boon to democracy and democratic practices. According to one popular theme, both e-mail and web pages give ordinary people powers of communication that have hitherto been the preserve of the relatively wealthy (Graham 1999, p. 79). So the Internet can be expected to close the influence gap between wealthy citizens and ordinary citizens, a weakness of many procedural democracies.
