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 derKrogt,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.

Frame Reflection Lab: a Playful Method for Frame Reflection on Synthetic Biology.Marjoleine G. van der Meij,Anouk A. L. M. Heltzel,Jacqueline E. W. Broerse &Frank Kupper -2018 -NanoEthics 12 (2):155-172.detailsSynthetic biology is an emerging technology that asks for inclusive reflection on how people frame the field. To unravel how we can facilitate such reflection, this study evaluates the Frame Reflection Lab. Building upon playfulness design principles, the FRL comprises a workshop with video-narratives and co-creative group exercises. We studied how the FRL facilitated frame reflection by organizing workshops with various student groups. Analysis of 12 group conversations and 158 mini-exit surveys yielded patterns in first-order reflection as well as patterns (...) in second-order reflection. Also patterns in participants’ framing of synthetic biology could be induced; participants’ viewpoints converged to some extent, yet with openness to individual viewpoint differences. Although the FRL method fortified the reflection processes of participants, the narratives and the workshop’s flexible format could inhibit the reflection too. Therefore, we advise designers of future frame reflection methods to apply stronger conversational facilitation and narratives of slightly mysterious yet identifiable narrators, in case e.g. video-narratives are created and used to scaffold the reflection process. Nevertheless, we argue that the use of a playful frame reflection method like the FRL could function well as a step to precede more application-specific deliberation or decision-making on synthetic biology and as a method for the collection of contemporary citizen viewpoints plus rationales underlying these, for the further responsible development of the emerging field.

The benefits of argumentation are cross-culturally robust: The case of Japan.H. Mercier,M. Deguchi,J.-B. Van der Henst &H. Yama -2016 -Thinking and Reasoning 22 (1):1-15.detailsThanks to the exchange of arguments, groups outperform individuals on some tasks, such as solving logical problems. However, these results stem from experiments conducted among Westerners and they could be due to cultural particularities such as tolerance of contradiction and approval of public debate. Other cultures, collectivistic cultures in particular, are said to frown on argumentation. Moreover, some influential intellectual movements, such as Confucianism, disapprove of argumentation. In two experiments, the hypothesis that Easterners might not share the benefits of argumentation (...) was tested. In Experiment 1, Japanese participants had to solve a standard logical problem individually and then in groups. They performed significantly better in groups. In Experiment 2, Japanese participants had to estimate the weight of various animals. They did so individually, then after learning of another participant's estimates, then after discussing these estimates with the other participant, and then indi.. (shrink)
Fundamental Problems in Quantum Physics.M. Ferrero &Alwyn van der Merwe (eds.) -1995 - Springer.detailsFor many physicists quantum theory contains strong conceptual difficulties, while for others the apparent conclusions about the reality of our physical world and the ways in which we discover that reality remain philosophically unacceptable. This book focuses on recent theoretical and experimental developments in the foundations of quantum physics, including topics such as the puzzles and paradoxes which appear when general relativity and quantum mechanics are combined; the emergence of classical properties from quantum mechanics; stochastic electrodynamics; EPR experiments and Bell's (...) Theorem; the consistent histories approach and the problem of datum uniqueness in quantum mechanics; non-local measurements and teleportation of quantum states; quantum non-demolition measurements in optics and matter wave properties observed by neutron, electron and atomic interferometry. Audience: This volume is intended for graduate students of physics and those interested in the foundations of quantum theory. (shrink)

Formal models of “resource depletion”.Hilde M. Huizenga,Maurits W. van der Molen,Anika Bexkens &Wery Pm van den Wildenberg -2013 -Behavioral and Brain Sciences 36 (6):694-695.detailsThe opportunity cost model (OCM) aims to explain various phenomena, among which the finding that performance degrades if executive functions are used repeatedly (). We argue that an OCM account of resource depletion requires two unlikely assumptions, and we discuss an alternative that does not require these assumptions. This alternative model describes the interplay between executive function and motivation.
Introduction: The Undivided Big Banana.Jeffrey M. Perl &Johan M. G. van der Dennen -2014 -Common Knowledge 20 (3):412-418.detailsIn this introduction to the first installment of the Common Knowledge symposium “Peace by Other Means,” the journal's editor questions the assumptions that underwrite standard approaches in the social sciences to the issue of how non-state, tribal societies have dealt with matters of war and peace. He in particular examines and finds wanting the approach that Jared Diamond takes in The World until Yesterday: What Can We Learn from Traditional Societies?. Whereas Diamond's theme is that modern states can learn much (...) about many things from traditional hunter-gatherer societies, with respect to peacemaking and peace-keeping he finds traditional societies distinctly inferior, and the arguments by which he reaches this conclusion are tautological and also beg the question. This prefatory essay explains that “Peace by Other Means” will analyze and detail non-Western and premodern European means of keeping peace that modern theorists of conflict resolution are reluctant to credit or incompetent to assess.

The Why and How of Enabling the Integration of Social and Ethical Aspects in Research and Development.Steven M. Flipse,Maarten Ca van der Sanden &Patricia Osseweijer -2013 -Science and Engineering Ethics 19 (3):703-725.detailsNew and Emerging Science and Technology (NEST) based innovations, e.g. in the field of Life Sciences or Nanotechnology, frequently raise societal and political concerns. To address these concerns NEST researchers are expected to deploy socially responsible R&D practices. This requires researchers to integrate social and ethical aspects (SEAs) in their daily work. Many methods can facilitate such integration. Still, why and how researchers should and could use SEAs remains largely unclear. In this paper we aim to relate motivations for NEST (...) researchers to include SEAs in their work, and the requirements to establish such integration from their perspectives, to existing approaches that can be used to establish integration of SEAs in the daily work of these NEST researchers. Based on our analyses, we argue that for the successful integration of SEAs in R&D practice, collaborative approaches between researchers and scholars from the social sciences and humanities seem the most successful. The only way to explore whether that is in fact the case, is by embarking on collaborative research endeavours. (shrink)
Meta-Argumentation Modelling I: Methodology and Techniques.Guido Boella,Dov M. Gabbay,Leendert van der Torre &Serena Villata -2009 -Studia Logica 93 (2-3):297 - 355.detailsIn this paper, we introduce the methodology and techniques of metaargumentation to model argumentation. The methodology of meta-argumentation instantiates Dung's abstract argumentation theory with an extended argumentation theory, and is thus based on a combination of the methodology of instantiating abstract arguments, and the methodology of extending Dung's basic argumentation frameworks with other relations among abstract arguments. The technique of meta-argumentation applies Dung's theory of abstract argumentation to itself, by instantiating Dung's abstract arguments with meta-arguments using a technique called flattening. (...) We characterize the domain of instantiation using a representation technique based on soundness and completeness. Finally, we distinguish among various instantiations using the technique of specification languages. (shrink)
Assessment of physician-assisted death by members of the public prosecution in The Netherlands.J. M. Cuperus-Bosma,G. van der Wal,C. W. Looman &P. J. van der Maas -1999 -Journal of Medical Ethics 25 (1):8-15.detailsOBJECTIVES: To identify the factors that influence the assessment of reported cases of physician-assisted death by members of the public prosecution. DESIGN/SETTING: At the beginning of 1996, during verbal interviews, 12 short case-descriptions were presented to a representative group of 47 members of the public prosecution in the Netherlands. RESULTS: Assessment varied considerably between respondents. Some respondents made more "lenient" assessments than others. Characteristics of the respondents, such as function, personal-life philosophy and age, were not related to the assessment. Case (...) characteristics, i.e. the presence of an explicit request, life expectancy and the type of suffering, strongly influenced the assessment. Of these characteristics, the presence or absence of an explicit request was the most important determinant of the decision whether or not to hold an inquest. CONCLUSIONS: Although the presence of an explicit request, life expectancy and the type of suffering each influenced the assessment, each individual assessment was dependent on the assessor. The resulting danger of legal inequality and legal uncertainty, particularly in complicated cases, should be kept to a minimum by the introduction of some form of protocol and consultation in doubtful or boundary cases. The notification procedure already promotes a certain degree of uniformity in the prosecution policy. (shrink)
Setting Up Spaces for Collaboration in Industry Between Researchers from the Natural and Social Sciences.Steven M. Flipse,Maarten C. A. van der Sanden &Patricia Osseweijer -2014 -Science and Engineering Ethics 20 (1):7-22.detailsPolicy makers call upon researchers from the natural and social sciences to collaborate for the responsible development and deployment of innovations. Collaborations are projected to enhance both the technical quality of innovations, and the extent to which relevant social and ethical considerations are integrated into their development. This could make these innovations more socially robust and responsible, particularly in new and emerging scientific and technological fields, such as synthetic biology and nanotechnology. Some researchers from both fields have embarked on collaborative (...) research activities, using various Technology Assessment approaches and Socio-Technical Integration Research activities such as Midstream Modulation. Still, practical experience of collaborations in industry is limited, while much may be expected from industry in terms of socially responsible innovation development. Experience in and guidelines on how to set up and manage such collaborations are not easily available. Having carried out various collaborative research activities in industry ourselves, we aim to share in this paper our experiences in setting up and working in such collaborations. We highlight the possibilities and boundaries in setting up and managing collaborations, and discuss how we have experienced the emergence of ‘collaborative spaces.’ Hopefully our findings can facilitate and encourage others to set up collaborative research endeavours.

Neural constructivism or self-organization?Peter C. M. Molenaar &Han L. J. van der Maas -2000 -Behavioral and Brain Sciences 23 (5):783-784.detailsThree arguments are given to show that neural constructivism lacks an essential ingredient to explain cognitive development. Based on results in the theory of adaptive signal analysis, adaptive biological pattern information and self-organization in nonlinear systems of information processing, it is concluded that neural constructivism should be further extended to accommodate the occurrence of phase transitions generating qualitative development in the sense of Piaget.
Distinct task-independent visual thresholds for egocentric and allocentric information pick up.Matthieu M. De Wit,John Van der Kamp &Rich Sw Masters -2012 -Consciousness and Cognition 21 (3):1410-1418.detailsThe dominant view of the ventral and dorsal visual systems is that they subserve perception and action. De Wit, Van der Kamp, and Masters suggested that a more fundamental distinction might exist between the nature of information exploited by the systems. The present study distinguished between these accounts by asking participants to perform delayed matching , pointing and perceptual judgment responses to masked Müller–Lyer stimuli of varying length. Matching and pointing responses of participants who could not perceptually judge stimulus length (...) at brief durations remained sensitive to veridical stimulus length , but not the illusion , which was effective at long durations. Distinct thresholds for egocentric and allocentric information pick up were thus evident irrespective of whether perception or action responses were required. It was concluded that the dorsal and ventral systems may be delineated fundamentally by fast egocentric- and slower allocentric information pick up, respectively. (shrink)
Enfleshed: ecologies of entities and beings.Kristiina Koskentola &Marjolein van der Loo (eds.) -2023 - Eindhoven: Onomatopee Projects.detailsEnfleshed: Ecologies of Entities and Beings brings together practitioners, thinkers, and artists from across Eurasia to collectively explore multispecies ecologies. The volume reflects anthrodecentric and embodied approaches to collaboration and knowledge production -- processes that are always interwoven with a multitude of entities and actors. In this book, the contributions flow like a river across the Eurasian continent, branching out into all directions. The contributors engage in an exploration of experimental epistemic alliances, which operate as a way to learn and (...) make new dialogic relations. The conflicts generated by ecological disaster, war, the global economy, identity politics, and the power structures of knowledge production and science here intertwine with shamanisms, rituals, magic, speculation, politics, and poetics. How do we imagine an active and implicated role of the human as one being among other beings? What might this entail, and what might this generate?"--Page 4 of cover. (shrink)

Midstream Modulation in Biotechnology Industry: Redefining What is ‘Part of the Job’ of Researchers in Industry. [REVIEW]Steven M. Flipse,Maarten Ca van der Sanden &Patricia Osseweijer -2013 -Science and Engineering Ethics 19 (3):1141-1164.detailsIn response to an increasing amount of policy papers stressing the need for integrating social and ethical aspects in Research and Development (R&D) practices, science studies scholars have conducted integrative research and experiments with science and innovation actors. One widely employed integration method is Midstream Modulation (MM), in which an ‘embedded humanist’ interacts in regular meetings with researchers to engage them with the social and ethical aspects of their work. While the possibility of using MM to enhance critical reflection has (...) been demonstrated in academic settings, few attempts have been made to examine its appropriateness in industry. This paper describes the outcomes of a case study aiming to find out firstly whether MM can effectively be deployed to encourage and facilitate researchers to actively include social and ethical aspects in their daily R&D practice, and secondly to what extent the integration activities could form an integral part of the engaged industrial researchers’ professional activities. Our data show that after MM, researchers display increased reflexive awareness on the social and ethical aspects of their work and acknowledge the relevance and utility of such aspects on their daily practice. Also, all participants considered actively reflecting on social and ethical aspects to be part of their work. Future research on the role of MM in industrial settings could focus on how to embed social and ethical integration as a regular part of innovation practice. We suggest that one possibility would be through aligning social and ethical aspects with innovation Key Performance Indicators. (shrink)
Nurses' Moral Problems in Dialisys.Maaike Hermsen &Marjolein van der Donk -2009 -Nursing Ethics 16 (2):184-191.detailsThis article gives an overview of the moral problems experienced and described by nurses working in a dialysis unit in the Netherlands. The nurses raised a wide variety of issues that they considered were moral problems, which were grouped into seven topics. A selection of cases are described, one of which is analysed using the Nijmegen method of ethical case deliberation. This method facilitates practical approaches to the different types of moral problems encountered. The argument is made that, owing to (...) their specific moral position and responsibility, nurses' contribution to ethical reflection in ward discussions should be valued more. All caregivers involved are indispensable in developing a basis for well-reasoned decisions when deliberating about moral problems. (shrink)
What is the best standard for the standard of care in clinical research?Rieke van der Graaf &Johannes J. M. van Delden -2009 -American Journal of Bioethics 9 (3):35 – 43.detailsDuring the past decennium, one of the main issues discussed in research ethics has been focused on the care that should be provided to the control group in a clinical trial. This discussion is also called the standard of care debate . Current international research ethics guidelines contain a wide variety of standards for the standard of care—including the provision of the highest attainable, the best available, the best current, a proven , and an established effective treatment. In this article, (...) we systematically review the currently used standards and argue that none of the current standards is adequate to serve as a universal standard for the standard of care. Alex London has made a substantial proposal for a universal standard, but universally adopting his standard is problematic. In this article, we propose a revised version of London's standard.

“Managing” Corporate Community Involvement.Judith M. van der Voort,Katherina Glac &Lucas C. P. M. Meijs -2009 -Journal of Business Ethics 90 (3):311-329.detailsIn academic research, many attempts have been undertaken to legitimize corporate community involvement by showing a business case for it. However, much less attention has been devoted to building understanding about the actual dynamics and challenges of managing CCI in the business context. As an alternative to existing predominantly static and top-down approaches, this paper introduces a social movement framework for analyzing CCI management. Based on the analysis of qualitative case study data, we argue that the active role of employees (...) pressuring for CCI policies and practices, as well as the organization audience responses to their efforts, are at the core of the challenges involved in managing CCI. These challenges also pose limits to how far CCI can be extended to a “business as usual” activity. (shrink)
(1 other version)Établir la qualité des preuves pour les situations de décision complexes et controversées.Jeroen P. Van der Sluijs,Arthur C. Petersen,Peter H. M. Janssen,James S. Risbey &Jerome R. Ravetz -2012 -Hermès: La Revue Cognition, communication, politique 64 (3):, [ p.].detailsLes décisions politiques sur les risques environnementaux complexes font fréquemment intervenir des éléments scientifiques contestés. Il n’y a généralement pas de « faits » qui conduisent à une politique correcte unique. Les éléments de preuve qui sont intégrés dans les avis scientifiques destinés à une décision politique nécessitent une évaluation de leur qualité. En 2003, l’Agence néerlandaise d’évaluation environnementale a adopté une méthode standardisée, désignée sous le nom de « guide », dans le cadre de laquelle les principaux aspects de (...) la production et de l’utilisation des connaissances sont présentés grâce à une liste de contrôle visant à l’évaluation et à la communication des incertitudes. Dans cet article, nous présentons des résultats de l’application de ce guide à la controverse sur les risques des particules en suspension. La délibération active sur l’incertitude dans un contexte d’expertise entraîne un processus d’apprentissage commun entre les experts et les décideurs politiques, ce qui conduit à une meilleure prise de conscience du phénomène d’incertitude et de ses implications politiques.Policy decisions on complex environmental risks often involve disputed science. Typically, there are no “ facts” to support a single unequivocally correct policy. The evidence provided in scientific studies for policy-making decisions requires high-quality assessment. In 2003, the Netherlands Environmental Assessment Agency adopted a standardized method, referred to as “guidelines”, whereby key quality aspects of knowledge production and use are presented in the form of a checklist for uncertainty assessments and communication. In this article, we present the outcomes of applying the guidelines in controversies on the risks of ambient particulate matter. In the policy–advisory context, active deliberation on uncertainty produces a common learning process for advisors and policy makers, which leads to a deeper understanding and increased awareness of the phenomenon of uncertainty and its policy implications.

This article focuses on the implementation of MCD in nursing homes and the questions how and where to organize MCD. The purpose of this study was to evaluate one way of organizing MCD in two Dutch nursing homes. In both of these nursing homes the MCD groups had a heterogeneous composition and were organized (...) apart from existing institutional communication structures. As part of a naturalistic evaluation, systematic observations, interviews and focus groups were completed. The findings indicate that the heterogeneous composition and MCD meetings separate from existing structures have benefits. However, the participants also reported negative experiences. This gives rise to the question whether a mixed MCD group which meets separately is an effective way to embed MCD as an instrument for reflection on moral issues in daily practice. We conclude that there is no single answer to that question. In the end, the two implementation strategies (i.e. within existing communication structures and a mixed MCD group) can be complementary to each other. (shrink)
