AimVisual functions of the dorsal stream are considered vulnerable in children with early brain damage. Considering the recognition of objects in suboptimal representations a dorsal stream dysfunction, we examined whether children with early brain damage and impaired object recognition had either general or selective dorsal stream dysfunctions.MethodIn a group of children with early brain damage we evaluated the dorsal stream functioning. To determine whether these patients had an increased risk of a dorsal stream dysfunction we compared the percentage of patients (...) with impaired object recognition, assessed with the L94, with the estimated base rate. Then we evaluated the performance levels on motion perception, visual attention and visuomotor tasks in patients with and without object recognition abnormalities. A general dorsal stream dysfunction was considered present if a patient showed at least one abnormally low score in two out of three additional dorsal stream functions.ResultsSix of the eighteen patients with object recognition problems scored abnormally low on at least two additional dorsal stream functions. This was significantly higher than the base rate. The difference of 24.1% between the patients with and without object recognition problems was not significant. Of the patients with object recognition problems 72.2% had at least 1 dorsal weakness, whereas this was only the case in 27.3% of patients without object recognition problems. Compared to patients with normal object recognition, patients with object recognition problems scored significantly more abnormally low on motion perception and visual attention but did not differ on visuomotor skills.ConclusionChildren with object recognition problems seem at risk for other dorsal stream dysfunctions, but dysfunctions might be rather specific than general. Multiple functions/aspects should be evaluated in neuropsychological assessment of children at risk. (shrink)

The study of intellectual humility is still in its early stages and issues of definition and measurement are only now being explored. To inform and guide the process of defining and measuring this important intellectual virtue, we conducted a series of studies into the implicit theory – or ‘folk’ understanding – of an intellectually humble person, a wise person, and an intellectually arrogant person. In Study 1, 350 adults used a free-listing procedure to generate a list of descriptors, one for (...) each person-concept. In Study 2, 335 adults rated the previously generated descriptors by how characteristic each was of the target person-concept. In Study 3, 344 adults sorted the descriptors by similarity for each person-concept. By comparing and contrasting the three person-concepts, a complex portrait of an intellectually humble person emerges with particular epistemic, self-oriented, and other-oriented dimensions.

Three 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.

Dans son nouveau livre, Marie-Paule Ha bouleverse les idées reçues sur le rôle des Françaises dans les colonies. Se concentrant sur l’Indochine, Ha affirme que les femmes françaises n’ont pas tracé une ligne de démarcation stricte entre les colonisateurs et les colonisés. Elles ont bien plutôt inventé des façons diverses de vivre aux colonies, en fonction de leur position sociale, de leur privilèges de « race » et de leur accès à l’administration coloniale. Dans l’introduction, M.-P. Ha situe...

PurposeTo explore the mindfulness practice, its long-term effects, facilitators and barriers, in clinical clerkship students 2 years after participation in an 8-week mindfulness-based stress reduction training.MethodA qualitative study was performed by semi-structured in-depth interviews with 16 clinical clerkship students selected by purposive sampling. Students had participated in a MBSR training 2 years before and were asked about their current mindfulness practice, and the long-term effects of the MBSR training. Thematic analysis was conducted using the constant comparison method. Data saturation was (...) reached after 16 interviews.ResultsMost interviewees were still engaged in regular, predominantly informal, mindfulness practice, although some discontinued mindfulness practice and reported an “unchanged lifestyle.” Three main themes came forward; “focused attention and open awareness” during daily activities as core elements of long-term mindfulness practice; “changes in behavior and coping” that resulted from taking a pause, reflecting, recognizing automatic behavioral patterns and making space for a conscious response; “integration in personal and professional life” by enhanced enjoyment of daily activities, improved work-life-balance and making different career choices. Barriers and facilitators in starting and maintaining mindfulness practice were understanding and intention as “pre-conditions”; practical, personal, and professional factors of students in maintaining practice.ConclusionTwo years after participation in a MBSR training, many interviewees were still engaged in mindfulness practice contributing to both personal and professional changes. In light of the high clerkship demands, MBSR training could be a valuable addition to medical curricula, supporting medical students in developing necessary competencies to become well-balanced professionals.

If you want to understand McDowell's spatial metaphors when he talks about perceptual knowledge, place him side-by-side with Dretske on perceptual knowledge. Though McDowell shows no evidence of reading Dretske's writings on knowledge from the late 1960s onwards (McDowell mentions "Epistemic Operators" once in passing), McDowell gives the same four arguments as Dretske for the conclusion that knowledge requires "conclusive" reasons that rule of the possibility of mistake. Despite various differences, we think it is best to read McDowell as re-discovering (...) Dretske on perceptual knowledge. Since Dretske is easy to understand, all of McDowell's metaphors become easy to understand. But what about McDowell's disjunctivism? Turns out McDowell is not an ontological disjunctivist, and his epistemological disjunctivism is really just the banal point that some perceptual experiences provide conclusive reasons for perceptual belief and some do not. Perceptual experiences are either conclusive or inconclusive. Dretske would agree. (shrink)

The norm of assertion, to be in force, is a social norm. What is the content of our social norm of assertion? Various linguistic arguments purport to show that to assert is to represent oneself as knowing. But to represent oneself as knowing does not entail that assertion is governed by a knowledge norm. At best these linguistic arguments provide indirect support for a knowledge norm. Furthermore, there are alternative, non-normative explanations for the linguistic data (as in recent work from (...) Van Elswyk). Direct arguments would rely on normative judgments about the permissibility or impermissibility of assertions with and without the speaker knowing the content asserted. John Turri's work experimental results purport to show that our norm of assertion is factive, and probably knowledge. But as a number of recent experimentalists (Kneer, Reuter and Broessel, Marsili and Wiegmann) have shown, Turri's results rely on the problemmatic use of 'should' as in 'Maria should assert that she owns a 1990 watch.' Correcting for this, these experimentalists provide strong evidence that our norm of assertion is not factive. The standard reply to evidence like this from the assertion of unlucky falsehoods is the excuse maneuver. But Marsili and Wiegmann, following Turri's protocol for testing for excuse validation, show that participants who judge that assertions unlucky falsehoods are permissible are not guilty of excuse validation. Given our current understanding of the experimental evidence, knowledge is not our norm of assertion. (shrink)

Theological schools are well situated to create intentional cultures for the purpose of spiritual formation. Indeed, most schools of theology have this goal as an essential part of their mission as well as a requirement for continued accreditation. And yet, the measurement of spiritual formation over time is fraught with challenges. This article seeks to address some of these challenges by means of developing a meta-theory of positive change/growth which would eventually serve as a theoretical basis for the development of (...) a generalizable and reliable measurement tool.

There is a nationwide resurgence of tuberculosis in the country’s urban centers; New York City stands at the forefront of this resurgence. The root causes are increased homelessness, drug addiction and poverty, all symbols of deteriorating social and economic conditions in the city. The inadequate level of public health resources devoted to TB has also contributed to its spread. Still, even with these factors, it is questionable whether the escalating number of TB cases in this country would have occurred without (...) the reservoir of immunosuppressed persons, who are less resistant to the disease, created by the AIDS epidemic. The fear and urgency of this public health crisis, which has been emerging since the beginning of the last decade, are fueled by the rise of TB strains resistant to the first-line drugs and by the disease’s contagiousness.

Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

La nueva enfermedad del coronavirus de 2019 (Covid-19), producida por el coronavirus del Síndrome Respiratorio Agudo Severo 2 (SARS-CoV-2), es una pandemia que está creando una creciente crisis sanitaria mundial, dada su novedad, su alcance y sus inicialmente limitadas opciones de tratamiento eficaz. En efecto, se sabe poco acerca de las intervenciones no farmacéuticas óptimas para evitar la morbilidad y mortalidad causadas por él, y también se conoce poco sobre la rentabilidad y aspectos éticos de dichas intervenciones. Por lo tanto, (...) éste es el primer análisis ético y de rentabilidad de las medidas de contención del Covid-19 que se conoce (así como de las medidas de cuarentena de la población para cualquier pandemia en particular), con el fin de ayudar a los sistemas de salud y a los gobiernos a garantizar la atención clínica más rentable que pueda proporcionarse equitativamente al mayor número posible de pacientes, durante esta pandemia y en las futuras crisis mundiales que sean similares. Este análisis utilizó la metodología adoptada por los Centros para el Control y la Prevención de Enfermedades (CDC), cifras comúnmente aceptadas como entradas, y los supuestos mínimos tanto extremos como del mundo real para proporcionar los resultados más sólidos y confiables posibles. El análisis de costos indicó que en los escenarios extremos, o en el mejor de los casos para las medidas de contención del Covid-19 durante la cuarentena de la población, hay una relación de costo-efectividad de $154.86 millones de dólares gastados por cada muerte evitada, y un costo neto de $1.92 billones a nivel mundial. En el mundo real, esta intervención tiene una proporción de 2,520 millones de dólares gastados por cada muerte evitada y un costo neto de 1,99 billones de dólares. La ética del contrato social personalista, tal y como se articula en el popular sistema ético de derechos y deberes de las Naciones Unidas, pone de manifiesto la especial preocupación por el hecho de que estos confinamientos pueden derivar en injusticias poco éticas perpetuadas por los Estados, de manera que socavan las vidas y las libertades individuales, al tiempo que afectan de manera des- proporcionada a las comunidades de menores ingresos, especialmente a las minorías raciales. Este estudio sugiere, por tanto, que la práctica prevalente de la cuarentena entre la población, en comparación con las precauciones de tipo estándar y las intervenciones más específicas, puede proporcionar un beneficio neto inadecuado por su costo financiero y ético. En un momento de escasez mundial, que pone a prueba la capacidad de los sistemas sanitarios para detectar y atender adecuadamente a los pacientes con Covid-19, especialmente en los países en desarrollo y en las comunidades desatendidas, este estudio respalda que se dediquen menos recursos a intervenciones con una relación costo- beneficio poco clara, y más recursos a intervenciones más asequibles, éticas y equitativas, con mayores pruebas de sus beneficios netos para salvar vidas.

This article describes some potential uses of Bayesian estimation for time-series and panel data models by incorporating information from prior probabilities in addition to observed data. Drawing on econometrics and other literatures we illustrate the use of informative “shrinkage” or “small variance” priors while extending prior work on the general cross-lagged panel model. Using a panel dataset of national income and subjective well-being we describe three key benefits of these priors. First, they shrink parameter estimates toward zero or toward each (...) other for time-varying parameters, which lends additional support for an income → SWB effect that is not supported with maximum likelihood. This is useful because, second, these priors increase model parsimony and the stability of estimates and thus improve out-of-sample predictions and interpretability, which means estimated effect should also be more trustworthy than under ML. Third, these priors allow estimating otherwise under-identified models under ML, allowing higher-order lagged effects and time-varying parameters that are otherwise impossible to estimate using observed data alone. In conclusion we note some of the responsibilities that come with the use of priors which, departing from typical commentaries on their scientific applications, we describe as involving reflection on how best to apply modeling tools to address matters of worldly concern.

Behavior, language, development, identity, and science—all of these phenomena are commonly characterized as 'social' in nature. But what does it mean to be 'social'? Is there any intrinsic 'mark' of the social shared by these phenomena? In the first book to shed light on this foundational question, twelve distinguished philosophers and social scientists from several disciplines debate the mark of the social. Their varied answers will be of interest to sociologists, anthropologists, philosophers, psychologists, and anyone interested in the theoretical foundations (...) of the social sciences. (shrink)

Public health and service delivery programmes, interventions and policies are typically developed and implemented for the primary purpose of effecting change rather than generating knowledge. Nonetheless, evaluations of these programmes may produce valuable learning that helps determine effectiveness and costs as well as informing design and implementation of future programmes. Such studies might be termed ‘opportunistic evaluations’, since they are responsive to emergent opportunities rather than being studies of interventions that are initiated or designed by researchers. However, current ethical guidance (...) and registration procedures make little allowance for scenarios where researchers have played no role in the development or implementation of a programme, but nevertheless plan to conduct a prospective evaluation. We explore the limitations of the guidance and procedures with respect to opportunistic evaluations, providing a number of examples. We propose that one key missing distinction in current guidance is moral responsibility: researchers can only be held accountable for those aspects of a study over which they have control. We argue that requiring researchers to justify an intervention, programme or policy that would occur regardless of their involvement prevents or hinders research in the public interest without providing any further protections to research participants. We recommend that trial consent and ethics procedures allow for a clear separation of responsibilities for the intervention and the evaluation. (shrink)

Conscientious objections (CO) can be disruptive in a variety of ways and may disadvantage patients and colleagues who must step-in to assume care. Nevertheless, nurses have a right and responsibility to object to participation in interventions that would seriously harm their sense of integrity. This is an ethical problem of balancing risks and responsibilities related to patient care. Here we explore the problem and propose a nonlinear framework for exploring the authenticity of a claim of CO from the perspective of (...) the nurse and of those who must evaluate such claims. We synthesized the framework using Rest’s Four Component Model of moral reasoning along with tenets of the International Council of Nursing’s (ICN) Code of Ethics for Nurses and insights from relevant ethics and nursing ethics literature. The resulting framework facilitates evaluating potential consequences of a given CO for all involved. We propose that the framework can also serve as an aid for nurse educators as they prepare students for practice. Gaining clarity about the sense in which the concept of conscience provides a defensible foundation for objecting to legally, or otherwise ethically, permissible actions, in any given case is critical to arriving at an ethical and reasonable plan of action.

Clinical trials emerged in rapid succession as the COVID-19 pandemic created an unprecedented need for life-saving therapies. Fair and equitable subject selection in clinical trials offering investigational therapies ought to be an urgent moral concern. Subject selection determines the distribution of risks and benefits, and impacts the applicability of the study results for the larger population. While Research Ethics Committees monitor fair subject selection within each trial, no standard oversight exists for subject selection across multiple trials for the same disease. (...) Drawing on the experience of multiple clinical trials at a single academic medical centre in the USA, we posit that concurrent COVID-19 trials are liable to unfair and inequitable subject selection on account of scientific uncertainty, lack of transparency, scarcity and, lastly, structural barriers to equity compounded by implicit bias. To address the critical gap in the current literature and international regulation, we propose new ethical guidelines for research design and conduct that bolsters fair and equitable subject selection. Although the proposed guidelines are tailored to the research design and protocol of concurrent trials in the COVID-19 pandemic, they may have broader relevance to single COVID-19 trials. (shrink)
