To controlforceaccurately under a wide range of behavioral conditions, the central nervous system would either require a detailed, continuously updated representation of the state of each muscle (and the load against which each is acting) or else force feedback with sufficient gain to cope with variations in the properties of the muscles and loads. The evidence for force feedback with adequate gain or for an appropriate central representation is not sufficient to conclude that force is the major controlled variable in (...) normal limb movements.Morton's hypothesis, thatlengthis controlled by a follow-up servo, has a number of difficulties related to the delays, gains, variability, and specificity in feedback pathways comprising potential servo loops. However, experimental evidence is consistent with these pathways providing servo assistance for some movements produced by coactivation of α- and static γ-motoneurons. Dynamic γ-motoneurons may provide an additional input for adaptive control of different types of movements.The idea that feedback is used to compensate for changes in musclestiffnesshas received experimental support under static postural conditions. However, reflexes tend to increase rather than decrease the range of variation in muscle stiffness during some cyclic movements. Theoretical problems associated with the regulation of stiffness are also discussed. The possibilities of separate control systems forvelocityorviscosityare considered, but the evidence is either negative or lacking. I conclude that different physical variables can be controlled depending on the type of limb movement required. The concept of stiffness regulation is also useful under some conditions, but should probably be extended to the regulation of the visco-elastic properties (i.e., the mechanical impedance) of a muscle or joint.

This volume is a collection of original essays by eminent philosophers written for R. B. Braithwaite's eightieth birthday to celebrate his work and teaching. In one way or another, all the essays reflect his central concern with the impact of science on our beliefs about the world and the responses appropriate to that. Together they testify to the signal importance of his contributions in areas of philosophy bearing on this concern: the philosophy of science, especially of the statistical sciences, theories (...) of belief and of probability, decision theory and games theory. This book, which includes a full bibliography of Professor Braithwaite's work, will interest advanced students and professionals in the fields of philosophy and psychology. (shrink)

Comprehension and recall of informed consent was assessed after the study closure in the parents/guardians of a birth cohort of children participating in an intensive three-year diarrhoeal surveillance. A structured questionnaire was administered by field workers who had not participated in the study's follow-up protocol. Of 368 respondents, 329 (89.4 per cent) stated that the study was adequately explained during enrolment, but only 159 (43.2 per cent) could recall that it was on diarrhoea. Nearly half (45.9 per cent) of the (...) respondents stated that they would not have participated if free medical treatment was not provided, although the free medical clinic was not offered at enrolment. Spousal approval (82.9 per cent) was the most important factor in the decision to participate. In the multivariate analysis, maternal education was associated with increased awareness about the disease under study: mothers without any formal education had the lowest awareness (OR = 3.47, 95 per cent CI = 1.60–7.51). Despite a high compliance with the study protocol, retention of understanding about the research study was low over a long period of time. Although the local government provides free healthcare in the study area, respondents cited free healthcare as an important reason for participation, highlighting the need for true health equity before meaningful informed consent can be obtained.

Early versions of satellite and radiosonde datasets suggested that the tropical surface had warmed more than the troposphere, while climate models consistently showed tropospheric amplification of surface warming in response to human-caused increases in greenhouse gases. We revisit such comparisons here using new observational estimates of surface and tropospheric temperature changes. We find that there is no longer a serious discrepancy between modeled and observed trends in the tropics. Our results contradict a recent claim that all simulated temperature trends in (...) the tropical troposphere are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.This emerging reconciliation of models and observations has two primary explanations. First, because of changes in the treatment of buoy and satellite information, new surface temperature datasets yield slightly reduced tropical warming relative to earlier versions. Second, recently developed satellite and radiosonde datasets now show larger warming of the tropical lower troposphere. In the case of a new satellite dataset from remote sensing systems, enhancedRSS warming is due to an improved procedure of adjusting for inter-satellite biases. When the RSS-derived tropospheric temperature trend is compared with four different observed estimates of surface temperature change, the surface warming is invariably amplified in the tropical troposphere, consistent with model results. Even if we use data from a second satellite dataset with smaller tropospheric warming than in remote sensing systems RSS, observed tropical lapse rates are not significantly different from those in all model simulations.Our results contradict a recent claim that all simulated temperature trends in the tropical troposphere and in tropical lapse rates are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.

R.G. Collingwood defined historical knowledge as essentially ‘scientific’, and saw the historian's task as the ‘re-enactment of past thoughts’. The author argues the need to go beyond Collingwood, first by demonstrating the authenticity of available evidence, and secondly, using Namier as an example, by considering methodology as well as epistemology, and the need to relate past thoughts to their present context. The ‘law of the consumption of time’ encourages historians to focus on landmark events, theories and generalisations, thus breaking from (...) Collingwood's emphasis on fidelity to past ideas and interpreting the past from the concepts of the present. This conflict can only be reconciled by the study of historiography. (shrink)

Visual research methods like photography and digital storytelling are increasingly used in health and social sciences research as participatory approaches that benefit participants, researchers, and audiences. Visual methods involve a number of additional ethical considerations such as using identifiable content and ownership of creative outputs. As such, ethics committees should use different assessment frameworks to consider research protocols with visual methods. Here, we outline the limitations of ethics committees in assessing projects with a visual focus and highlight the sparse knowledge (...) on how researchers respond when they encounter ethical challenges in the practice of visual research. We propose a situated approach in relation to visual methodologies that encompasses a negotiated, flexible approach, given that ethical issues usually emerge in relation to the specific contexts of individual research projects. Drawing on available literature and two case studies, we identify and reflect on nuanced ethical implications in visual research, like tensions between aesthetics and research validity. The case studies highlight strategies developed in-situ to address the challenges two researchers encountered when using visual research methods, illustrating that some practice implications are not necessarily addressed using established ethical clearance procedures. A situated approach can ensure that visual research remains ethical, engaging, and rigorous. (shrink)

E.R. Dodds’ 1959 edition of Plato’s Gorgias is a conventional treatment of this dialogue, aimed at audiences interested in close study of the text. Dodds himself regretted this outcome. He felt he had lost sight of an earlier goal, formulated at a time of political turmoil on the eve of WorldWar II, of using the Gorgias to bring out ‘both the resemblance and the difference between Plato’s situation and that of the intellectual today’. The present paper attempts to reconstruct that (...) goal, as it survives residually in his edition, surfaces in his The Greeks and the Irrational, and appears in some writings from the 1930s, particularly in unpublished lectures. Dodds did frequently juxtapose ancient and modern conceptions of the intellectual, and in a way that cast Plato in a positive light, as someone politically engaged and self-critical, and acutely sensitive, as Dodds himself was, to the political implications of social psychology.

In this paper a formalized logic of propositions, PA1, is presented. It is proven consistent and its relationships to traditional logic, to PM ([15]), to subjunctive (including contrary-to-fact) implication and to the “paradoxes” of material and strict implication are developed. Apart from any intrinsic merit it possesses, its chief significance lies in demonstrating the feasibility of a general logic containing theprinciple of subjunctive contrariety, i.e., the principle that ‘Ifpwere true thenqwould be true’ and ‘Ifpwere true thenqwould be false’ are incompatible.

This book is not a study of Plato's philosophy, but a contribution to the literary interpretation of the dialogues, through analysis of their formal structure, ...

Marcus Aurelius, Roman emperor from 161 to 180 A.D., is renowned for his just rule and long frontier wars. But his lasting fame rests on his Meditations, a bedside book of reflections and self-admonitions written during his last years, that provide unique insights into the mind of an ancient ruler and contain many passages of pungent epigram and poetic imagery. This study is designed to make the Meditations more accessible to the modern reader. Rutherford carefully explains the historical and philosophical (...) background, charts the main themes and tendencies of Marcus's thought, and relates stylistic detail to the intellectual and moral outlook of the author. His goal is to define Marcus's aims, attitudes, and styles more precisely and restore his work to the position it held in the past, that of a spiritual classic which can be read and enjoyed by people who are not professional scholars.

This research explores the contextual approach within Christian-Jewish religious education, addressing a notable gap in existing literature and offering fresh insights into the application of the Contextual Teaching and Learning (CTL) model within Christian contexts. Through a qualitative literature study employing a three-step methodology, including an in-depth analysis of Deuteronomy 11:19–20, this study reveals that this biblical text provides both educational guidance and theological significance, serving as a foundational support for the CTL model in Christian-Jewish religious education. The integration of (...) digital media into biblical sources holds promise for future research, while the central challenge lies in harmonising life experiences and empirical phenomena with biblical reflections to seamlessly integrate inquiry processes and pedagogical phases, with potential avenues for further exploration in scripture models endorsing CTL. This research provides valuable insights for educators, parents and policymakers in Indonesia and beyond, advancing educational research in contextualised teaching models within religious education.Contribution: This article demonstrates that the CTL model in the digital era has the potential to revolutionise religious education and profoundly impact learners, making it a significant scientific contribution in the context of Christian-Jewish religious education.

The question of whether or not children may be used as subjects in non-therapeutic research projects has generated a great deal of debate and received answers varying from 'no, never' to 'yes, if societal interests are served'. It has been claimed that a Kantian, deontological ethics would necessarily rule out such research, since valid consent would be impossible. The present paper gives a deontological argument for allowing children to be subjects in certain types of research.

There is growing interest in clinical ethics. However, we still have sparse knowledge about what is actually going on in the everyday practice of clinical ethics consultations. This paper introduces a descriptive evaluation tool to present, discuss and compare how clinical ethics case consultations are actually carried out. The tool does not aim to define ‘best practice’. Rather, it facilitates concrete comparisons and evaluative discussions of the role, function, procedures and ideals inherent in clinical ethics case consultation practices. The tool (...) was developed during meetings of the European Clinical Ethics Network. Based on written reports and participation in the network meetings, the development and the content of the tool and the results of its application in presenting and discussing 10 case consultations are summarized. The tool facilitated understanding of the details of clinical ethics case consultations across individuals and institutions with various experiences and cultures, and comparison between various practices.

The concept of energy, the premier concept of physics and indeed of all science, is here investigated from the standpoint of its early historical origin and the philosophical implications thereof. The fundamental assumption is made that the root of the concept is the notion of invariance or constancy in the midst of change. Salient points in the development of this idea are presented from ancient times up to the publication of Lagrange'sMécanique Analytique (1788).

It is a common complaint against moral philosophers that their abstract theorising bears little relation to the practical problems of everyday life. Professor Braithwaite believes that this criticism need not be inevitable. With the help of the Theory of Games he shows how arbitration is possible between two neighbours, a jazz trumpeter and a classical pianist, whose performances are a source of mutual discord. The solution of the problem in the lecture is geometrical, and is based on the formal analogy (...) between the logic of the situation and the geometry of a parabola. But an appendix provides the alternative algebraic treatment of a general two-person collaboration situation. (shrink)

Journal of the History of Biology provides a fifty-year long record for examining the evolution of the history of biology as a scholarly discipline. In this paper, we present a new dataset and preliminary quantitative analysis of the thematic content of JHB from the perspectives of geography, organisms, and thematic fields. The geographic diversity of authors whose work appears in JHB has increased steadily since 1968, but the geographic coverage of the content of JHB articles remains strongly lopsided toward the (...) United States, United Kingdom, and western Europe and has diversified much less dramatically over time. The taxonomic diversity of organisms discussed in JHB increased steadily between 1968 and the late 1990s but declined in later years, mirroring broader patterns of diversification previously reported in the biomedical research literature. Finally, we used a combination of topic modeling and nonlinear dimensionality reduction techniques to develop a model of multi-article fields within JHB. We found evidence for directional changes in the representation of fields on multiple scales. The diversity of JHB with regard to the representation of thematic fields has increased overall, with most of that diversification occurring in recent years. Drawing on the dataset generated in the course of this analysis, as well as web services in the emerging digital history and philosophy of science ecosystem, we have developed an interactive web platform for exploring the content of JHB, and we provide a brief overview of the platform in this article. As a whole, the data and analyses presented here provide a starting-place for further critical reflection on the evolution of the history of biology over the past half-century. (shrink)

Requests by patients or their families for treatment which the patient's physician considers to be "inappropriate" are becoming more frequent than refusals of treatment which the physician considers appropriate. Such requests are often based on the patient's religious beliefs about the attributes of God (sovereignty, omnipotence), the attributes of persons (sanctity of life), or the individual's personal relationship with God (communication, commands, etc). We present four such cases and discuss some of the basic religious tenets of the three Abrahamic faith (...) traditions as they relate to such requests. We suggest that religious reasons for requesting "inappropriate" treatment are "special" and deserve serious consideration. We offer guidance to assist clinicians and clinical ethicists as they attempt to resolve these conflicts, emphasising the importance of understanding the religious beliefs of the patient/surrogate and suggesting the assistance of a religious interpreter. We suggest open discussion with patients and families of both the clinical situation and the theological basis for these requests. We also suggest that clinicians use additional religious doctrines or principles from patients' own traditions to balance the reasons behind the requests. We conclude that most persistent requests for "inappropriate" treatment should be honoured. (shrink)
