The Reception of Aristotle's History of Animals in the Marginalia of Some Latin Manuscripts of Michael Scot's Arabic-Latin Translation.M. I. vanOppenraayAafke -2003 -Early Science and Medicine 8 (4):387-403.detailsA considerable number of the thirteenth and early fourteenth-century manuscripts of Michael Scot's Arabic-Latin translation of Aristotle's De animalibus display a system of guiding marginal glosses. These glosses are usually added by a later hand with respect to the hand that had written the text. The manuscripts were not only annotated for personal use, but also so as to allow for a better use in compiling commentaries, encyclopaedias and compendia. We can say that the marginalia form the main, if not (...) only, key to our understanding today of the use that readers made of the text. Apart from offering a mere explanation of the contents, we can see that their interest in the text was chiefly related to biblical exegesis and to scientific and medical knowledge. The approach to the text was often allegorical and moralizing in character. Some remarks reflect the reader's own experience and associations in relation to the text. (shrink)

Diversity in decentralized clinical trials: prioritizing inclusion of underrepresented groups.Tessa I. van Rijssel,Johannes J. M. van Delden,Bart Lagerwaard,Mira G. P. Zuidgeest &Ghislaine J. M. W. van Thiel -2025 -BMC Medical Ethics 26 (1):1-8.detailsThe importance of more diversity of study populations in clinical trials is currently widely acknowledged. Decentralized clinical trial (DCT) approaches are presented as a potential means to broaden diversity by eliminating several barriers to participation. However, the precise meaning of, and objectives related to diversity in DCTs remain unclear. Diversity runs the risk of becoming a ‘buzzword’: widely acknowledged to be important, yet prone to multiple interpretations and challenging to implement in practice. We argue that the aim of increasing diversity (...) in clinical trials requires clear and well-substantiated specifications. We analyze the concept of diversity and the ethical requirements surrounding fair participant selection within the context of clinical research, in order to further specify and operationalize the aim of increasing diversity in the context of DCTs. Through analyzing the concept of diversity and ethical requirements for fair participant selection, we propose that diversity should be specified in a way that improves the position of the groups that are currently most underrepresented in the research context. In practice, this entails that, in order to contribute to diversity, the selection of participants should prioritize (i) gaining scientific knowledge on groups for which this is lacking, and (ii) inclusion of underrepresented groups in research when appropriate considering a study’s objectives, and risks and benefits. Our analysis facilitates translating the aim of increasing diversity with DCTs to more specific and actionable objectives for recruitment and inclusion. Moreover, it contributes to a further specification of the concept of diversity and fair participant selection in research contexts. (shrink)
Michael Scot’s Translation of Aristotle’s Books on Animals and the Pleasures of Knowledge.Aafke M.

Which Benefits Can Justify Risks in Research?Tessa I. van Rijssel,Ghislaine J. M. W. van Thiel,Helga Gardarsdottir,Johannes J. M. van Delden &on Behalf of the Trials@Home Consortium -2024 -American Journal of Bioethics 25 (5):65-75.detailsResearch ethics committees (RECs) evaluate whether the risk-benefit ratio of a study is acceptable. Decentralized clinical trials (DCTs) are a novel approach for conducting clinical trials that potentially bring important benefits for research, including several collateral benefits. The position of collateral benefits in risk-benefit assessments is currently unclear. DCTs raise therefore questions about how these benefits should be assessed. This paper aims to reconsider the different types of research benefits, and their position in risk-benefit assessments. We first propose a categorization (...) of research benefits, based on the types of benefits that can be distinguished from the literature and ethical guidelines. Secondly, we will reconsider the position of collateral benefits. We argue that these benefits are not fundamentally different from other benefits of research and can therefore be included in risk-benefit assessments of DCTs. (shrink)
The Ethics of Decentralized Clinical Trials and Informed Consent: Taking Technologies’ Soft Impacts into Account.Tessa I. van Rijssel,Ghislaine J. M. W. van Thiel &Johannes J. M. van Delden -forthcoming -Health Care Analysis:1-12.detailsDecentralized clinical trials (DCTs) have the potential to advance the conduct of clinical trials, but raise several ethical issues, including obtaining valid informed consent. The debate on the ethical issues resulting from digitalization is predominantly focused on direct risks relating to for example data protection, safety, and data quality. We submit however, that a broader view on ethical aspects of DCTs is needed to touch upon the new challenges that come with the DCT practice. Digitalization has impacts that go beyond (...) its direct purposes, by shaping behaviors, experiences, social relations, and values. We examine four elements of the informed consent procedure that are affected by DCTs, while taking these soft impacts of technologies into account: (i) informing participants and testing understanding, (ii) freedoms in relation to responsibilities and burdens, (iii) trust in participant-researcher relations, and (iv) impacts on the concept of privacy. Our analysis reveals that a broad view is key for optimal conduct of DCTs. In addition, it provides insight into the ethical impacts of DCTs on informed consent. Technologies such as DCTs potentially have profound impacts which are not immediately addressed by the existing regulatory frameworks, but nonetheless important to recognize. These findings can guide future practices of DCTs to foster the important values of clinical research in this novel approach for conducting clinical trials. (shrink)

The study of granulocyte kinetics by mathematical analysis of DNA labelling.William M. O'Fallon,Richard I. Walker &H. Robert Van Der Vaart -1971 -Acta Biotheoretica 20 (3-4):95-124.detailsA commonly used experimental procedure for the study of granulocyte kinetics involves the labelling and subsequent tracing of granulocyte DNA. Following the introduction of a label into the system, observations are made periodically on the concentration of label in the DNA of granulocytes taken from the circulating blood. A mathematical model for the expected value of this concentration has been derived, studied, and related to experimental observations from studies using P32 as a label. Insofar as the derivation of the model (...) accurately incorporates the relevant aspects of granulocyte kinetics, the model will be useful in the interpretation of the experimental observations in terms of these kinetics.Among other things, study of the model indicates that the assumption of “flash” labelling made with respect to some labels is quite crucial and needs to be examined critically. It has also been necessary to make adjustments to allow for the observed emergence of labelled cells from the marrow soon after label introduction. In addition, despite a high degree of confounding of parameter effects it has been possible to suggest bounds on some of the parameters of the model for some species. The bounds will be refined as the model is improved and more data become available. Study and development of the model continues with particular interest in generalizations to include the diseased state chronic granulocytic leukemia. (shrink)
Dotting the I's and crossing the T's: autonomy and/or beneficence? The 'fetus as a patient' in maternal–fetal surgery.H. Catarina M. L. Rodrigues,Paul P. van den Berg &Marcus Düwell -2013 -Journal of Medical Ethics 39 (4):219-223.detailsChervenak 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.

Plasticity mechanisms of genetically distinct Purkinje cells.Stijn Voerman,Robin Broersen,Sigrid M. A. Swagemakers,Chris I. De Zeeuw &Peter J. van der Spek -2024 -Bioessays 46 (6):2400008.detailsDespite its uniform appearance, the cerebellar cortex is highly heterogeneous in terms of structure, genetics and physiology. Purkinje cells (PCs), the principal and sole output neurons of the cerebellar cortex, can be categorized into multiple populations that differentially express molecular markers and display distinctive physiological features. Such features include action potential rate, but also their propensity for synaptic and intrinsic plasticity. However, the precise molecular and genetic factors that correlate with the differential physiological properties of PCs remain elusive. In this (...) article, we provide a detailed overview of the cellular mechanisms that regulate PC activity and plasticity. We further perform a pathway analysis to highlight how molecular characteristics of specific PC populations may influence their physiology and plasticity mechanisms. (shrink)

The Importance of Intra-Organizational Networking for Younger Versus Older Workers: Examining a Multi-Group Mediation Model of Individual Task Performance Enhancement.Beatrice I. J. M. Van der Heijden,Peter M. Kruyen &Guy Notelaers -2020 -Frontiers in Psychology 11:606383.detailsThe purpose of this paper is to investigate the effect of intra-organizational networking on individual task performance, via employability. Moreover, this study also examines whether this relationship differs for younger (<40 years) versus older employees (≥40 years). A self-report questionnaire was distributed among a sample of employees working in a range of different types of organizations (n= 374). We conclude that employability fully mediates the relationship between intra-organizational networking and individual task performance. However, this mediation effect did not vary between (...) younger and older employees. This study extends past research by applying a human capital perspective (in particular, social capital) and life-span development frameworks for explaining employability and task performance enhancement across one’s working life. It provides useful insights for stimulating career development and individual performance growth, by means of social capital, herewith increasing the individual employee’s chance to survive in nowadays’ labor markets.

Development of a core set of gait features and their potential underlying impairments to assist gait data interpretation in children with cerebral palsy.Marjolein M. van der Krogt,Han Houdijk,Koen Wishaupt,Kim van Hutten,Sarah Dekker &Annemieke I. Buizer -2022 -Frontiers in Human Neuroscience 16:907565.detailsBackgroundThe interpretation of clinical gait data in children with cerebral palsy (CP) is time-consuming, requires extensive expertise and often lacks transparency. Here we aimed to develop a set of look-up tables to support this process, linking typical gait features as present in CP to their potential underlying impairments.MethodsWe developed an initial core set of gait features and their potential underlying impairments based on biomechanical reasoning, literature and clinical experience. This core set was further specified through a Delphi process in a (...) multidisciplinary group of experts in gait analysis of children with CP and evaluated on 20 patient cases. The likelihood of the listed gait feature–impairment relationships was scored by the expert panel on a five-point scale.ResultsThe final core set included 120 relevant gait feature–impairment relations including likelihood scores. This set was presented in the form of look-up tables in both directions, i.e., sorted by gait features with potential underlying impairment, and sorted by impairments with potential related gait features. The average likelihood score for the relations was 3.5 ± 0.6 (range 2.1–4.6).ConclusionThe developed set of look-up tables linking gait features and impairments, can assist gait analysts and clinicians in standardized biomechanical reasoning, to support treatment decision-making for gait impairments in children with CP.

Tracking Infant Development With a Smartphone: A Practical Guide to the Experience Sampling Method.Marion I. van den Heuvel,Anne Bülow,Vera E. Heininga,Elisabeth L. de Moor,Loes H. C. Janssen,Mariek Vanden Abeele &Myrthe G. B. M. Boekhorst -2021 -Frontiers in Psychology 12.detailsThe COVID-19 pandemic has forced developmental researchers to rethink their traditional research practices. The growing need to study infant development at a distance has shifted our research paradigm to online and digital monitoring of infants and families, using electronic devices, such as smartphones. In this practical guide, we introduce the Experience Sampling Method – a research method to collect data, in the moment, on multiple occasions over time – for examining infant development at a distance. ESM is highly suited for (...) assessing dynamic processes of infant development and family dynamics, such as parent-infant interactions and parenting practices. It can also be used to track highly fluctuating family dynamics and routines. The aim of the current paper was to provide an overview by explaining what ESM is and for what types of research ESM is best suited. Next, we provide a brief step-by-step guide on how to start and run an ESM study, including preregistration, development of a questionnaire, using wearables and other hardware, planning and design considerations, and examples of possible analysis techniques. Finally, we discuss common pitfalls of ESM research and how to avoid them. (shrink)
(1 other version)Happiness Quantified: A Satisfaction Calculus Approach.Bernard M. S. Van Praag &Ada Ferrer-I.-Carbonell -2004 - Oxford University Press UK.detailsHow do we measure happiness? Focusing on subjective measures as a proxy for welfare and well-being, this book finds ways to do that. Subjective measures have been used by psychologists, sociologists, political scientists, and, more recently, economists to answer a variety of scientifically and politically relevant questions. Van Praag, a pioneer in this field since 1971, and Ferrer-i-Carbonell present in this book a generally applicable methodology for the analysis of subjective satisfaction. Drawing on a range of surveys on people's satisfaction (...) with their jobs, income, housing, marriages, and government policy, among other areas of life, this book shows how satisfaction with life "as a whole" is an aggregate of these domain satisfactions. Using German, British, Dutch, and Russian data, the authors cover a wide range of topics, even some not usually considered part of economic study.The book makes a distinction between actual satisfaction levels and individual norms, and in this way complements Van Praag's earlier work within the Leyden School with his later work in "happiness research". Among the many topics covered, the authors discuss: individuals' memory and anticipation processes and the estimation of adaptation phenomena ; the effect of reference groups on income norms and satisfaction with income; the importance of climate for well-being, including the development of a climate-equivalence index; the trade-offs between chronic diseases and income when well-being is kept constant; the damage of aircraft noise on well-being; the construction of a new talent tax tariff; and inequality from a satisfaction perspective, including the definition of "satisfaction inequalities", a natural extension of income inequality and poverty.This groundbreaking book presents new and fruitful methodology that consitutes a welcome addition to the social sciences.

Aggression and violence around the world: A model of CLimate, Aggression, and Self-control in Humans.Paul A. M. Van Lange,Maria I. Rinderu &Brad J. Bushman -2017 -Behavioral and Brain Sciences 40:1-63.detailsWorldwide there are substantial differences within and between countries in aggression and violence. Although there are various exceptions, a general rule is that aggression and violence increase as one moves closer to the equator, which suggests the important role of climate differences. While this pattern is robust, theoretical explanations for these large differences in aggression and violence within countries and around the world are lacking. Most extant explanations focus on the influence of average temperature as a factor that triggers aggression, (...) or the notion that warm temperature allows for more social interaction situations in which aggression is likely to unfold. We propose a new model, CLimate, Aggression, and Self-control in Humans, that helps us to understand differences within and between countries in aggression and violence in terms of differences in climate. Lower temperatures, and especially larger degrees of seasonal variation in climate, call for individuals and groups to adopt a slower life history strategy, a greater focus on the future, and a stronger focus on self-control. The CLASH model further outlines that slow life strategy, future orientation, and strong self-control are important determinants of inhibiting aggression and violence. We also discuss how CLASH differs from other recently developed models that emphasize climate differences for understanding conflict. We conclude by discussing the theoretical and societal importance of climate in shaping individual and societal differences in aggression and violence. (shrink)
‘We Should View Him as an Individual’: The Role of the Child’s Future Autonomy in Shared Decision-Making About Unsolicited Findings in Pediatric Exome Sequencing.W. Dondorp,I. Bolt,A. Tibben,G. De Wert &M. Van Summeren -2021 -Health Care Analysis 29 (3):249-261.detailsIn debates about genetic testing of children, as well as about disclosing unsolicited findings (UFs) of pediatric exome sequencing, respect for future autonomy should be regarded as a prima facie consideration for not taking steps that would entail denying the future adult the opportunity to decide for herself about what to know about her own genome. While the argument can be overridden when other, morally more weighty considerations are at stake, whether this is the case can only be determined in (...) concrete cases. Importantly, when children grow into adolescents, respect for future autonomy will have to give way to respecting their emerging autonomy. When pediatric exome sequencing is done for complex conditions not involving developmental delay, respect for the child’s future or emerging autonomy should be a primary consideration for those charged with deciding on behalf of the child. Building on what Emanuel and Emanuel have termed the ‘deliberative model’ of shared decision making, we argue that if parents fail to give these considerations their due, professionals should actively invite them to do so. Taking a directive stance may be needed in order to make sure that the future or emerging autonomy of the child are duly considered in the decision-making process, but also to help the parents and themselves to shape their respective roles as responsible care-givers.

The risk-benefit task of research ethics committees: An evaluation of current approaches and the need to incorporate decision studies methods. [REVIEW]Johannes J. M. Van Delden Rosemarie D. L. C. Bernabe, Ghislaine J. M. W. Van Thiel, Jan A. M. Raaijmakers -2012 -BMC Medical Ethics 13 (1):6.detailsBackgroundResearch ethics committees (RECs) are tasked to assess the risks and the benefits of a trial. Currently, two procedure-level approaches are predominant, the Net Risk Test and the Component Analysis.DiscussionBy looking at decision studies, we see that both procedure-level approaches conflate the various risk-benefit tasks, i.e., risk-benefit assessment, risk-benefit evaluation, risk treatment, and decision making. This conflation makes the RECs’ risk-benefit task confusing, if not impossible. We further realize that RECs are not meant to do all the risk-benefit tasks; instead, (...) RECs are meant to evaluate risks and benefits, appraise risk treatment suggestions, and make the final decision.ConclusionAs such, research ethics would benefit from looking beyond the procedure-level approaches and allowing disciplines like decision studies to be involved in the discourse on RECs’ risk-benefit task.

To Leave or Not to Leave? A Multi-Sample Study on Individual, Job-Related, and Organizational Antecedents of Employability and Retirement Intentions.Pascale M. Le Blanc,Maria C. W. Peeters,Beatrice I. J. M. Van der Heijden &Llewellyn E. van Zyl -2019 -Frontiers in Psychology 10:474977.detailsIn view of the aging and dejuvenation of the working population and the expected shortages in employees’ skills in the future, it is of utmost importance to focus on older workers’ employability in order to prolong their working life until, or even beyond, their official retirement age. The primary aim of the current study was to examine the relationship between older workers’ employability (self-)perceptions and their intention to continue working until their official retirement age. In addition, we studied the role (...) of potential antecedents of their perceived employability at three different levels: training and education in current expertise area as well as in an adjacent expertise area (individual level factor), learning value of the job (job level factor), and organizational career management practices (organizational level factor). Data were collected by means of e-questionnaires that were distributed among two groups of Dutch older (45-plus) white collar workers. The samples consisted of 223 employees of an insurance company, and 325 university workers, respectively. Our research model was tested separately in each sample using Structural Equation Modeling. We controlled for effects of respondents’ (self-)perceived health and (self-)perceived financial situation. Similar results were found for both samples. First, the relationship of perceived employability with the intention to continue working until one’s retirement age was positive, whereas the relationship between a perceived good financial situation with the intention to continue working until one’s retirement age was negative. Secondly, as regards the potential antecedents, results showed that the learning value of the job was positively related to perceived employability. In addition, an employee’s perception of good health is a relevant correlate of perceived employability. So, whereas perceived employability contributes to the intention to continue working until one’s retirement age, a good financial situation is a push factor to retire early. In order to promote the labor participation of older workers, this study indicates that organizations should focus on the learning possibilities that are inherent to one’s job rather than on providing additional training or career management. Further research is needed to test the generalizability of our results to other samples. (shrink)
How do 66 European institutional review boards approve one protocol for an international prospective observational study on traumatic brain injury?

Menon,Giuseppe Citerio,Nino Stocchetti &Erwin J. O. Kompanje -2020 -BMC Medical Ethics 21 (1):1-14.detailsBackground The European Union aims to optimize patient protection and efficiency of health-care research by harmonizing procedures across Member States. Nonetheless, further improvements are required to increase multicenter research efficiency. We investigated IRB procedures in a large prospective European multicenter study on traumatic brain injury, aiming to inform and stimulate initiatives to improve efficiency. Methods We reviewed relevant documents regarding IRB submission and IRB approval from European neurotrauma centers participating in the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury. (...) Documents included detailed information on IRB procedures and the duration from IRB submission until approval. They were translated and analyzed to determine the level of harmonization of IRB procedures within Europe. Results From 18 countries, 66 centers provided the requested documents. The primary IRB review was conducted centrally or locally and primary IRB approval was obtained after one, two or three review rounds with a median duration of respectively 50 and 98 days until primary IRB approval. Additional IRB approval was required in 55% of countries and could increase duration to 535 days. Total duration from submission until required IRB approval was obtained was 114 days and appeared to be shorter after submission to local IRBs compared to central IRBs. Conclusion We found variation in IRB procedures between and within European countries. There were differences in submission and approval requirements, number of review rounds and total duration. Research collaborations could benefit from the implementation of more uniform legislation and regulation while acknowledging local cultural habits and moral values between countries. (shrink)
The ins and outs of unpacking the black box: Understanding motivation using a multi-level approach.F. Wurm,I. J. M. van der Ham &J. Schomaker -2025 -Behavioral and Brain Sciences 48:e49.detailsAlthough higher-level constructs often fail to explain the mechanisms underlying motivation, we argue that purely mechanistic approaches have limitations. Lower-level neural data help us identify “biologically plausible” mechanisms, while higher-level constructs are critical to formulate measurable behavioral outcomes when constructing computational models. Therefore, we propose that a multi-level, multi-measure approach is required to fully unpack the black box of motivated behavior.
Choice Functions and Hard Choices.M. Van Hees,A. Jitendranath &R. I.

Our objective is to present a systematic treatment of the axiomatic structure of such situations. To do so, we draw on and contribute to the study of choice functions that can be indecisive, i.e., that may fail to select a non-empty set for some menus. In this more general framework, we present new characterizations of two well-known choice (...) rules, the maximally dominant choice rule and the top-cycle choice rule. Together with existing results, this yields an understanding of the circumstances in which hard choices arise. (shrink)
Teaching domain-specific skills before peer assessment skills is superior to teaching them simultaneously.M. J. van Zundert,K. D. Könings,D. M. A. Sluijsmans &J. J. G. van Merriënboer -2012 -Educational Studies 38 (5):541-557.detailsInstruction in peer assessment of complex task performance may cause high cognitive load, impairing learning. A stepwise instructional strategy aimed at reducing cognitive load was investigated by comparing it with a combined instructional strategy in an experiment with 128 secondary school students (mean age 14.0?years; 45.2% male) with the between-subjects factor instruction (stepwise, combined). In the stepwise condition, study tasks in Phase 1 were domain-specific and study tasks in Phase 2 had both domain-specific and peer assessment components. In the combined (...) condition, these two components were present in all tasks in both phases. Final performance (i.e. speed and accuracy in domain-specific skills and peer assessment skills) showed no significant differences, but performance improved more from Phase 1 to Phase 2 in the stepwise condition than in the combined condition. The results suggest that, with complex study tasks, it might be beneficial to teach domain-specific skills before peer assessment skills. (shrink)
The Logic of Climate and Culture: Evolutionary and Psychological Aspects of CLASH.Paul A. M. Van Lange,Maria I. Rinderu &Brad J. Bushman -2017 -Behavioral and Brain Sciences 40:e104.detailsA total of 80 authors working in a variety of scientific disciplines commented on the theoretical model of CLimate, Aggression, and Self-control in Humans (CLASH). The commentaries cover a wide range of issues, including the logic and assumptions of CLASH, the evidence in support of CLASH, and other possible causes of aggression and violence (e.g., wealth, income inequality, political circumstances, historic circumstances, pathogen stress). Some commentaries also provide data relevant to CLASH. Here we clarify the logic and assumptions of CLASH (...) and discusses its extensions and boundary conditions. We also offer suggestions for future research. Regardless of whether none, some, or all of CLASH is found to be true, we hope it will stimulate future research on the link between climate and human behavior. Climate is one of the most presing issues of our time. (shrink)
