Lived music - multi-dimensional musical experience : Implications for music education.

In lieu of an abstract, here is a brief excerpt of the content:Learning Music:Embodied Experience in the Life-WorldEva Alerby and Cecilia FermIn the present age, which is often signified as post-modern or knowledge-intensive, the calls for learning echo loud. Discussions of learning, as well as teaching, permeate almost all levels and arenas of our society, and have a sure place in every-day conversation as well as scientific debate. The concept of learning can be understood and explained in many different (...) ways. Our intention in this article is to make visible and discuss how learning music can be understood and explained from a life-world approach.By life-world approach we mean that learning is constituted by the experiences that we are having in the world. From that perspective it can be seen as a process which leads to some kind of change, whose utmost purpose is—consciously or unconsciously—to create meaning and make managing the world possible. In addition, we stress that learning does not arise nor is formed in a vacuum, but instead is found in complex contexts. In turn this creates the necessity of making learning situated and contextualized.1How one understands how music is learned is consequently influenced not only by what fundamental assumptions one holds about learning but also by prevailing views of music. Furthermore, how musical ability is regarded and whether musicality is accepted as an emotional or cognitive phenomenon is also [End Page 177] important. Other assumptions that need to be considered are whether or not it is possible to divide musicality into smaller parts and if that is the case, what is the relationship between these parts. One further question that has to be illuminated is the question about biological and social influences on musicality.2 According to Sture Brändström,3 musicality is sometimes divided into two categories—absolute contra relativistic musicality. The first category implies that musicality is regarded as a native ability, already existing within the human being, an ability that some people have and others lack. The second category reflects an approach that assumes that musicality is something everybody can acquire, it can be learned and appropriated. We will return later to this issue.These questions reveal a dualistic approach, specifically: whether musicality is an emotional or a cognitive phenomenon, or absolute or relative, which in turn leads to the question of whether or not learning music is constituted within or outside the human being. To expose problems related to this dualistic approach in music education, we will examine musical learning using life-world phenomenology as a theoretical framework, a brief description of which follows.Phenomenology: A Way of ThinkingAt the turn into the twentieth century, the German philosopher, Edmund Husserl (1859-1938), named his philosophical approach phenomenology, and with that the development of modern phenomenology began. Phenomenology is both a method and a way of thought.4 He distinguished the fundamental principle of phenomenology as—'back to the things themselves.' According to Husserl it is through experiences that we gain access to things themselves. The concept of experience was essential to his formulation, and it became a key signature for the whole of phenomenology. His starting-point was how the world is experienced in a subjective way, and the aim was to find a way to describe the meaning of these subjective experiences. In other words, phenomenology has been summarized as a description of how the world is experienced by the person in the world.Various thinkers have interpreted phenomenology in different ways. Jan Bengtsson5 emphasized that phenomenological method should be named in the plural as methods. The phenomenology of the life-world, which was developed as an alternative to the so-called epoché, the special method of transcendental phenomenology, is a philosophy of the life-world without transcendental reduction. It is the life-world that constitutes the basis of our lives. It is the everyday world of our experiences, which we take for granted and where we live our lives. In other words it is the life-world that constitutes people's being-in-the-world.6 Through our existence we experience the concrete world in all its complexity, which is both historically and contextually dependent. Consequently... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Response to Eva Alerby and Cecilia Ferm, “Learning Music: Embodied Experience in the Life-World”C. Victor FungThe authors' choice of using phenomenology as a foundation of their inquiry is appropriate and appealing. They have, to a great extent, achieved their goal to explain music learning from a life-world approach. Descriptions of absolute musicality and relativistic musicality in the opening paragraphs remind me of the good old "nature versus (...) nurture" argument. Do the authors intend to relate musicality to musical ability or aptitude as defined by psychologists? If musicality is "the ability to make something of one's own," does it mean that the authors have taken on a relativistic view and believe that musicality can be acquired?At the onset of the essay, musicality is described as emotional or cognitive phenomena. I would be interested to know what role a psychomotor phenomenon plays in musicality. The authors later describe "motor knowledge" in the context of Merleau-Ponty's "maximum grip." Does it mean that "motor knowledge" or "maximum grip" in music is outside the realm of musicality?I have attempted to follow the authors' logic in answering the question: What is learning of music? The authors postulate that "knowledge does not always, and not in any way automatically, become exactly the same as the learning situation aimed for" and that "the aim of music education is to produce music knowledge." These propositions lead me to believe that the learning of music occurs in experiencing all types of musical activities, regardless of the musician's level of proficiency. In all types of musical activities, including different performances of the same repertoire by the same performer, the musician would find new knowledge that is being produced in his/her body. Therefore, I agree with the authors in that "bodily experience is the foundation for learning."I would like to respond to the issue of whether music learning occurs within [End Page 206] or outside of the human being. I enjoy reading how the authors borrow Merleau-Ponty's analogy of the blind man and his stick. They put it so beautifully that "the piano becomes an extension of the pianist's body, and the pianist can 'feel' its limitation." This leads me to ponder if there could be further extensions beyond the physical piano. We know that pianists make the strings in the piano vibrate through a lever mechanism. These vibrations travel through the air and arrive at the audience's ears. Then the vibrating energies are transmitted as electrical energies in the audience's nerve cells. The audience in turn may behave differently after such a complex transmission of energies at a performance. My question is: Is there an end to the "extension" of a musician's body? If so, where should it end? There is no doubt that the pianist relates to the world and learns about the world through the piano. Could the pianist learn about the world through the vibrations that the piano strings generate, through the air, and through the audience's hearing mechanism, brain cells, and behaviors? Is this what the authors meant by "the human ego is boundaryless and cannot be localized, and the ego is immanent in the whole system"? Regardless of how far the "extension" goes, how do we know if an "extension" has occurred? How can we validate an "extension" of a musician's ego"?It seems to me that the authors' discussions have focused on the tactile extension of the body. If the body can be extended like the stick for the blind man, would the air surrounding the blind man, including its smell, temperature, humidity, wind, and sound, be his extension too? When this question is transferred to a musician, would the total context of the musical event be the musician's extension of the body too? By "total context," I mean the cultural context, the environment (smell, temperature,...), and the people in the musical event.We are certain that music learning takes place when experiences and knowledge are incorporated in the body. We still have not solved the problem of whether music learning occurs within or outside of the human being, because the boundary of the... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Response to Eva Alerby and Cecilia Ferm, “Learning Music: Embodied Experience in the Life-World”Christine A. BrownI was recently asked to settle a friendly debate between two college graduates. The first, my daughter's boyfriend, argued that someone with talent and motivation could become as creative a composer without formal musical training as with it. The other, my daughter, vigorously countered that while someone might compose well on one's (...) own, the result would not be as versatile or thoughtfully developed as it could be with good formal instruction. I saw the musical educations of the debaters reflected in their arguments. My daughter had accumulated fourteen years of formal instruction in violin, cello, voice, and dance and took part in high school choral, theatrical, and orchestral performances. Her studies continued into college and from time to time she performs in community theater. Her boyfriend was the only musically trained member of his family. At his own request he studied piano for five years, later channeling his musical energies into a rock group. Though he did not study music in college, he continues to play keyboard and guitar. Both agree that the ongoing debate between them illustrates the strong connection between musical training and musical valuing. The life-world of their experiences shaped their judgments of musical quality and left imprints on their views of what matters more, talent or training. I will return to this scenario later.I find solid points of agreement with Eva Alerby and Cecilia Ferm starting with their premise that music learning is most effective when taught within a context. While some students prefer learning in a linear, rule-oriented setting, more often than not a musical concept will be comprehended best if it is first experienced within a variety of works. Regarding extra-musical contexts, furthermore, recent evidence supporting the integration of subject areas at the elementary level appears to extend the boundaries of musical learning in a positive direction. Additionally, the authors' description of embodied musical learning holds great interest. Their argument that musical learning must be appropriated within the body resonates strongly within me as I reflect upon performing and teaching piano. Experience with beginning level adult pianists suggests to me that once the awkwardness of newly-learned movements fades with time and effort, students often discover a close interaction between their physical and conceptual knowledge of music. Of related interest is the authors' definition of musicality as taking embodied musical knowledge and making it one's own. This surpasses physical mastery of an instrument and describes a personal [End Page 208] and emotional investment in music. It is at this point in the essay that the recognizable link between mind, body, and emotion in music is most clear.Alongside these engaging ideas, however, are statements throughout the essay that invite further questions or comments. First among these is the statement that the knowledge resulting from learning is not always what was intended or planned. While this is often the case, elaboration upon modes of knowledge in question would help clarify the authors' ideas. Since knowledge takes a variety of forms, as the authors imply, these forms should be explored, defined, and applied to the process of teaching and learning music.Related to that suggestion is my response to the statement that the aim of music education is to produce musical knowledge. I am assuming that musical knowledge includes an age-appropriate blend of performance skill, reading ability, ear training, historical and cultural connections, basic theoretical and stylistic understanding, and acquaintance with creative processes. In many regions of our country, public arts education has been de-valued to the extent that we must convince administrators, parents, and sometimes students, of its importance. Until this situation improves, I must personally consider the aim of music education as producing, alongside musical knowledge, the desire for music as a lifelong pursuit, be it active or passive. Without this desire, musical knowledge gained often goes unused. Referring to my opening anecdote, my daughter is not participating in music while her less extensively trained boyfriend is. I know of several students like her who gained expertise on an instrument and who have now stopped playing for... (shrink)

The 1985 paper by Carlos Alchourrón, Peter Gärdenfors, and David Makinson, “On the Logic of Theory Change: Partial Meet Contraction and Revision Functions” was the starting-point of a large and rapidly growing literature that employs formal models in the investigation of changes in belief states and databases. In this review, the first twenty-five years of this development are summarized. The topics covered include equivalent characterizations of AGM operations, extended representations of the belief states, change operators not included in the original (...) framework, iterated change, applications of the model, its connections with other formal frameworks, computatibility of AGM operations, and criticism of the model.

This book explains how the logic of theory change employs formal models in the investigation of changes in belief states and databases. The topics covered include equivalent characterizations of AGM operations, extended representations of the belief states, change operators not included in the original framework, iterated change, applications of the model, its connections with other formal frameworks, and criticism of the model.

Dennett, a philosopher, and Griffin, an ethologist, have recently presented influential arguments promoting the extended use of intentional language by students of animal behavior. This essay seeks to elucidate and to contrast the claims made by each of these authors, and to evaluate their proposals primarily from the perspective of a practicing comparative psychologist or ethologist. While Griffin regards intentional terms as explanatory, Dennett assigns them a descriptive function; the issue of animal consciousness is central to Griffin's program and only (...) tangentially related to Dennett's. The philosopher's arguments are founded upon a more coherent metaphysics, but Dennett neglects to substantiate his claim that animal competences can be most readily modelled by artificial intelligence specialists when they are described in intentional terms. Both authors assume that some examples of animal behavior should not be given an intentional characterization, but neither provides adequate guidelines for the identification of cases belonging to this negative set.

Since the BBS article in which Premack and Woodruff (1978) asked “Does the chimpanzee have a theory of mind?,” it has been repeatedly claimed that there is observational and experimental evidence that apes have mental state concepts, such as “want” and “know.” Unlike research on the development of theory of mind in childhood, however, no substantial progress has been made through this work with nonhuman primates. A survey of empirical studies of imitation, self-recognition, social relationships, deception, role-taking, and perspective-taking suggests (...) that in every case where nonhuman primate behavior has been interpreted as a sign of theory of mind, it could instead have occurred by chance or as a product of nonmentalistic processes such as associative learning or inferences based on nonmental categories. Arguments to the effect that, in spite of this, the theory of mind hypothesis should be accepted because it is more parsimonious than alternatives or because it is supported by convergent evidence are not compelling. Such arguments are based on unsupportable assumptions about the role of parsimony in science and either ignore the requirement that convergent evidence proceed from independent assumptions, or fail to show that it supports the theory of mind hypothesis over nonmentalist alternatives. Progress in research on theory of mind requires experimental procedures that can distinguish the theory of mind hypothesis from nonmentalist alternatives. A procedure that may have this potential is proposed. It uses conditional discrimination training and transfer tests to determine whether chimpanzees have the concept “see.” Commentators are invited to identify flaws in the procedure and to suggest alternatives. Key Words: apes; associative learning; concepts; convergence; deception; evolution of intelligence; folk psychology; imitation; mental state attribution; monkeys; parsimony; perspective-taking; primates; role-taking; self-recognition; social cognition; social intelligence; theory of mind.

What is the relationship between imitation and culture? This article charts how definitions of imitation have changed in the last century, distinguishes three senses of “culture” used by contemporary evolutionists (Culture1–Culture3), and summarises current disagreement about the relationship between imitation and culture. The disagreement arises from ambiguities in the distinction between imitation and emulation, and confusion between two explanatory projects—the anthropocentric project and the cultural selection project. I argue that imitation gives cultural evolution an inheritance mechanism for communicative and gestural (...) skills (but not technological skills), and cultural selection yields the cognitive mechanisms that make imitation possible.

Since the early 1980s, logical theories of belief revision have offered formal methods for the transformation of knowledge bases or “corpora” of data and beliefs. Early models have dealt with unconditional acceptance and integration of potentially belief-contravening pieces of information into the existing corpus. More recently, models of “non-prioritized” revision were proposed that allow the agent rationally to refuse to accept the new information. This paper introduces a refined method for changing beliefs by specifying constraints on the relative plausibility of (...) propositions. Like the earlier belief revision models, the method proposed is a qualitative one, in the sense that no numbers are needed in order to specify the posterior plausibility of the new information. We use reference beliefs in order to determine the degree of entrenchment of the newly accepted piece of information. We provide two kinds of semantics for this idea, give a logical characterization of the new model, study its relation with other operations of belief revision and contraction, and discuss its intuitive strengths and weaknesses.

En Heracles de Eurípides, el héroe en un ataque de locura mata a su familia. Una vez que toma conciencia de lo que ha hecho decide suicidarse, pero Teseo es capaz de persuadirlo para que no se quite la vida.

On Euripides' Heracles, the Dorian hero kills his family in a fit of madness. Once he is aware of what he has done, he decides to commit suicide, but Theseus persuades him otherwise. Given the peculiarity of this tragedy -in comparison with others that raise the same subject- I will analyse the healing power of the word in Heracles' recovery. I will focus on the influence of the sophist movement, particularly the figures of Protagoras and Gorgias in Euripides' work since I consider that the condition to develop a cure using words is the study that the sophists do on the persuasive function of the lógos.

Abstract:This article is based on results from research that addressed the ways young Black Metal musicians construct their musical learning and socialization. In this article we will focus on one of the strands in that study; a trace of a classic ideal from Bildung theory. Using Bildung theory, we explore similarities between the ideals and concepts in the expressed informal music education from Black Metal musicians and contemporary institutionalized music education. In this article the German and Nordic 18th century concept (...) of Bildung will be interpreted as the component that binds and contextualizes knowledge by a dialectic process with already inherited or internalized knowledge. Exploring, identifying, and comparing links between the educative process found within Black Metal and Bildung might at first sight seem to be both a pointless task and potentially reifying of problematic elements found within Black Metal. However, as we discuss, common features of Bildung and Black Metal, such as enlightenment through criticism of the taken-for-granted, a sublime Gesamtkunstwerk and a nihilist striving to become an image of God, help to reveal those ways Black Metal learning processes can be understood inthe light of Bildung theories. We do so in order to present tools for furthering the critical discussion of hegemonic music educational discourses. (shrink)

We propose a new class of multiple contraction operations — the system of spheres-based multiple contractions — which are a generalization of Grove’s system of spheres-based (singleton) contractions to the case of contractions by (possibly non-singleton) sets of sentences. Furthermore, we show that this new class of functions is a subclass of the class of the partial meet multiple contractions.

We introduce a constructive model of selective belief revision in which it is possible to accept only a part of the input information. A selective revision operator ο is defined by the equality K ο α = K * f(α), where * is an AGM revision operator and f a function, typically with the property ⊢ α → f(α). Axiomatic characterizations are provided for three variants of selective revision.

In this article we present a new class of multiple contraction functionswhich are a generalization of the epistemic entrenchment-based contractions (Grdenfors & Makinson, 1988) to the case of contractions by (possibly nonsingleton) sets of sentences and provide an axiomatic characterization for that class of functions. Moreover, we show that the class of epistemic entrenchment-based multiple contractions coincides with the class of system of spheres-based multiple contractions introduced in Fermé & Reis (2012).

Semi-contraction is a withdrawal operation defined by Fermé in "On the logic of theory change: Contraction without recovery." In this paper we propose: (1) an axiomatic characterization of semi-contraction; (2) an alternative construction for semi-contraction based on semi-saturatable sets, inspired by Levi's saturatable sets; (3) a special kind of semi-contraction that satisfies the Lindström and Rabinowicz interpolation thesis.

This paper focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. We propose for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction, proposed by Hansson [Han94] to construct classical AGM contractions and belief base contractions. This construction (...) works out the unsolved problem pointed out by Hansson in [Han99, pp. 369]. (shrink)

Background: Previous studies have investigated the effects of dance interventions on Parkinson’s motor and non-motor symptoms in an effort to develop an integrated view of dance as a therapeutic intervention. This within-subject study questions whether dance can be simply considered a form of exercise by comparing a Dance for Parkinson’s class with a matched-intensity exercise session lacking dance elements like music, metaphorical language, and social reality of art-partaking.Methods: In this repeated-measure design, 7 adults with Parkinson’s were tested four times; before (...) and after a Dance for Parkinson’s class, as well as before and after a matched-intensity exercise session. Physiological measures included heart rate and electrodermal activity. Self-reported affect and body self-efficacy were collected. Gait symmetry and dual task cost were analyzed using the 6 min walking test and Timed-Up-and-Go test, respectively.Results: Average heart rate was the same for both conditions, while electrodermal activity was higher during Dance for Parkinson’s. Significant differences were found in body self-efficacy, beauty subscale, symmetry of gait, and dual task performance.Conclusion: Dance, compared to an exercise intervention of matched intensity, yields different outcomes through the means of intrinsic artistic elements, which may influence affective responses, the experience of beauty, self-efficacy, and gait performance.

Metacognition – the ability to represent, monitor and control ongoing cognitive processes – helps us perform many tasks, both when acting alone and when working with others. While metacognition is adaptive, and found in other animals, we should not assume that all human forms of metacognition are gene-based adaptations. Instead, some forms may have a social origin, including the discrimination, interpretation, and broadcasting of metacognitive representations. There is evidence that each of these abilities depends on cultural learning and therefore that (...) cultural selectionmight shape humanmetacognition. The cultural origins hypothesis is a plausible and testable alternative that directs us towards a substantial new programme of research. (shrink)

RESUMO Neste artigo, analiso um conjunto de seis cartões comerciais pertencentes a uma duradoura campanha de marketing da Liebig Extract of Meat Co. A análise crítica dos textos promocionais produzidos na virada do século XX oferece insights significativos sobre os mecanismos discursivos que contribuíram para a hegemonização do capitalismo burguês. Diferentemente de outras formas de publicidade, os cartões comerciais não são rapidamente descartados e esquecidos; pelo contrário, eles podem se distanciar dos produtos anunciados para se tornar parte dos discursos populares (...) de instrução em massa. Como produtos e produtores de ideologias capitalistas, os anúncios são um local privilegiado de inscrição do capitalismo e, portanto, se prestam a uma análise crítica. Minha análise mostra como os textos selecionados se baseiam e texturizam os discursos do progresso, impregnados como crenças colonialistas e desencadeando uma cadeia de ações pela qual, mesmo antes de realmente obterem os cartões, são promulgadas ações e crenças capitalistas. ABSTRACT In this paper, I analyze a set of six trading cards belonging to Liebig’s Extract of Meat Co. long-standing marketing campaign. The critical analysis of promotional texts produced at the turn of the 20th century offer meaningful insights on the discursive mechanisms that contributed to the hegemonization of bourgeois capitalism. Unlike other forms of advertising, trading cards are not rapidly discarded and forgotten; on the contrary, they can detach themselves from the advertised products to become part of popular discourses of mass instruction. As both products and producers of capitalist ideologies, ads are a privileged site of inscription of capitalism, and thus lend themselves to a critical analysis. My analysis shows how the selected texts draws on and textures the discourses of progress, inculcated as colonialist beliefs and triggering an actional chain whereby, even before they actually obtained the cards, capitalist actions and beliefs are enacted.

The Protein Ontology (PRO) is designed as a formal and principled Open Biomedical Ontologies (OBO) Foundry ontology for proteins. The components of PRO extend from a classification of proteins on the basis of evolutionary relationships at the homeomorphic level to the representation of the multiple protein forms of a gene, including those resulting from alternative splicing, cleavage and/or posttranslational modifications. Focusing specifically on the TGF-beta signaling proteins, we describe the building, curation, usage and dissemination of PRO. PRO provides a framework (...) for the formal representation of protein classes and protein forms in the OBO Foundry. It is designed to enable data retrieval and integration and machine reasoning at the molecular level of proteins, thereby facilitating cross-species comparisons, pathway analysis, disease modeling and the generation of new hypotheses.

This thesis consists in six articles and a comprehensive summary. • The pourpose of the summary is to introduce the AGM theory of belief change and to exemplify the diversity and significance of the research that has been inspired by the AGM article in the last 25 years. The research areas associated with AGM was divided in three parts: criticisms, where we discussed some of the more common criticisms of AGM. Extensions where the most common extensions and variations of AGM (...) are presented and applications where we provided an overview of applications and connections with other areas of research. • Article I elaborates on the connection between partial meet contractions [AGM85] and kernel contractions [Han94a] in belief change theory. Also both functions are equivalent in belief sets, there are notequivalent in belief bases. A way to define incision functions from selection functions and vice versa is presented. It is explained under which conditions there are exact correspondences between selection and incision functions so that the same contraction operations can be obtained by using either of them. • Article II proposes an axiomatic characterization for ensconcement-based contraction functions, belief base functions proposed byWilliams and relates this function with other kinds of base contraction functions. • Article III adapts the Fermé and Hansson model of Shielded Contraction [FH01] as well as Hansson et all Credibility-Limited Revision [HFCF01] for belief bases, to join two of the many variations of the AGM model [AGM85], i.e. those in which knowledge is represented through belief bases instead of logic theories, and those in which the object of the epistemic change does not get the priority over the existing information as it is the case in the AGM model. • Article IV introduces revision by comparison a refined method for changing beliefs by specifying constraints on the relative plausibility of propositions. Like the earlier belief revision models, the method proposed is a qualitative one, in the sense that no numbers are needed in order to specify the posterior plausibility of the new information. The method uses reference beliefs in order to determine the degree of entrenchment of the newly accepted piece of information. Two kinds of semantics for this idea are proposed and a logical characterization of the new model is given. • Article V focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. This essay proposes for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction,proposed by Hansson [Han94a] to construct classical AGM contractions and belief base contractions. • Article VI relates AGM model with the DFT model proposed by Carlos Alchourrón [Alc93]. Alchourrón devoted his last years to the analysis of the notion of defeasible conditionalization. His definition of the defeasible conditional is given in terms of strict implication operator and a modal operator f which is interpreted as a revision function at the language level. This essay points out that this underlying revision function is more general than AGM revision. In addition, a complete characterization of that more general kind of revision that permits to unify models of revision given by other authors is given. (shrink)

The figure of the auteur continues to haunt the study of film, resisting both the poststructuralist charges that pointed to its absence and the histories of production demonstrating its pitfalls. In an era defined by the instability of identities and the recycling of works, Performing Authorship offers a refreshingly new take on the cinematic auteur, proposing that the challenges that once accelerated this figure's critical demise should instead pump new life into it. Performing Authorship is an illuminating analysis of films (...) by Jean-Luc Godard, Woody Allen, Agnes Varda, Orson Welles, Jean Rouch, Eduardo Coutinho and Sarah Turner that shows directors shifting between opposite movements towards authorial assertion and divestiture, palpability and disappearance, exposure and masking. In making this journey, Cecilia Sayad argues, the film author is not necessarily at the work's origin, nor does it constitute the end product. What the new concept of performing authorship describes is the making and unmaking of a subject"--Publisher website. (shrink)

Randomized Controlled Trials are currently the gold standard within evidence-based medicine. Usually, they are conducted as sequential trials allowing for monitoring for early signs of effectiveness or harm. However, evidence from early stopped trials is often charged with being biased towards implausibly large effects. To our mind, this skeptical attitude is unfounded and caused by the failure to perform appropriate conditioning in the statistical analysis of the evidence. We contend that a shift from unconditional hypothesis tests in the style of (...) Neyman and Pearson to conditional hypothesis tests gives a superior appreciation of the obtained evidence and significantly improves the practice of sequential medical trials, while staying firmly rooted in frequentist methodology.

The procedures for structuring clinical ethics case reflections in a childhood cancer care setting are presented, including an eight-step model. Four notable characteristics of the procedures are: members of the inter-professional health care team, not external experts, taking a leading role in the reflections; patients or relatives not being directly involved; the model explicitly addressing values and moral principles instead of focussing exclusively on the interests of involved parties; using a case-based (inductive) rather than principle-based (deductive) method. By discusing the (...) advantages and disadvantages of the proposed procedures, our paper aims to contribute to the literature on models and procedures for ethical analysis that can be used in clinical settings. It is suggested that our proposed procedures have some advantageous features when it comes to promoting health care staff’s learning to structure their thinking about ethical issues. (shrink)

Top scholars examine the work of Donald T. Campbell, one of the first to emphasize the social structure of science.

Five types of constructions are introduced for non-prioritized belief revision, i.e., belief revision in which the input sentence is not always accepted. These constructions include generalizations of entrenchment-based and sphere-based revision. Axiomatic characterizations are provided, and close interconnections are shown to hold between the different constructions.

Background: In previous research on ethics case reflection (ECR) sessions about specific cases, healthcare professionals in childhood cancer care were clarifying their perspectives on the ethical issue to resolve their main concern of consolidating care. When perspectives were clarified, consequences in the team included ‘increased understanding’, ‘group strengthening’ and ‘decision grounding’. Additional analysis of the data was needed on conditions that could contribute to the quality of ECR sessions. Objective: The aim of this study was to explore conditions for clarifying (...) perspectives during ECR sessions. Research design: Data were collected from observations and interviews and the results emerged from an inductive analysis using grounded theory. Participants and research context: Six observations during ECR sessions and 10 interviews were performed with healthcare professionals working in childhood cancer care and advanced paediatric homecare. Ethical considerations: The study was approved by a regional ethical review board. Participants were informed about their voluntary involvement and that they could withdraw their participation without explaining why. Findings: Two categories emerged: organizational enablers and barriers and team-related enablers and barriers. Organizational enablers and barriers included the following sub-categories: the timing of the ECR session, the structure during the ECR session and the climate during the ECR session. Sub-categories to team-related enablers and barriers were identified as space for inter-professional perspectives, varying levels of ethical skills and space for the patient’s and the family’s perspectives. Discussion: Space for inter-professional perspectives included the dominance of a particular perspective that can result from hierarchical positions. The medical perspective is relevant for understanding the child’s situation but should not dominate the ethical reflection. Conclusion: Conditions for ECR sessions have been explored and the new knowledge can be used when training facilitators as well as for those who organize/implement ECR sessions. Awareness of space for different perspectives, including the possible medical advantage over the nursing perspective, could reduce the somewhat unilateral attention and contribute to an inter-professionally shared reflection.

Background: Childhood cancer care involves many ethical concerns. Deciding on treatment levels and providing care that infringes on the child’s growing autonomy are known ethical concerns that involve the whole professional team around the child’s care. Objectives: The purpose of this study was to explore healthcare professionals’ experiences of participating in ethics case reflection sessions in childhood cancer care. Research design: Data collection by observations, individual interviews, and individual encounters. Data analysis were conducted following grounded theory methodology. Participants and research (...) context: Healthcare professionals working at a publicly funded children’s hospital in Sweden participated in ethics case reflection sessions in which ethical issues concerning clinical cases were reflected on. Ethical considerations: The children’s and their parents’ integrity was preserved through measures taken to protect patient identity during ethics case reflection sessions. The study was approved by a regional ethical review board. Findings: Consolidating care by clarifying perspectives emerged. Consolidating care entails striving for common care goals and creating a shared view of care and the ethical concern in the specific case. The inter-professional perspectives on the ethical aspects of care are clarified by the participants’ articulated views on the case. Different approaches for deliberating ethics are used during the sessions including raising values and making sense, leading to unifying interactions. Discussion: The findings indicate that ethical concerns could be eased by implementing ethics case reflection sessions. Conflicting perspectives can be turned into unifying interactions in the healthcare professional team with the common aim to achieve good pediatric care. Conclusion: Ethics case reflection sessions is valuable as it permits the discussion of values in healthcare-related issues in childhood cancer care. Clarifying perspectives, on the ethical concerns, enables healthcare professionals to reflect on the most reasonable and ethically defensible care for the child. A consolidated care approach would be valuable for both the child and the healthcare professionals because of the common care goals. (shrink)
