Quantum field theory (QFT) combines quantum mechanics with Einstein's special theory of relativity and underlies elementary particle physics. This book presents a philosophical analysis of QFT. It is the first treatise in which the philosophies of space-time, quantum phenomena, and particle interactions are encompassed in a unified framework. Describing the physics in nontechnical terms, and schematically illustrating complex ideas, the book also serves as an introduction to fundamental physical theories. The philosophical interpretation both upholds the reality of the quantum world (...) and acknowledges the irreducible cognitive elements in its representation. The interpretation is based on an analysis of our ways of thinking as the are embedded in the logical structure of QFT. The author argues that philosophical categories are significant only if they play active and essential roles in our knowledge and hence constitute part of the theories in actual use. Thus she regards physical theories as primary, extracts their categorical structure, and uses it to rethink key philosophical questions. Among the questions this book tries to answer are: What are the quantum properties independent of measurements? How do we refer to individual things in a continuous field? How do theories relate to objects? What are the general conditions of the world and of our ways of thinking that make possible our knowledge of the microscopic realm, which is so intangible and counterintuitive? As a penetrating analysis of vital themes in contemporary science, the book will engage the interest of students and professionals in physics and philosophy alike. (shrink)

The main object of this article is to contribute to a clearer use of the concept reflection. The question is whether reflection has become an overexposed and diluted medicine in educational thinking. To answer this question I will examine how reflection is understood and what direction and theoretical foundation the concept is based on. The article is a Habermas inspired interpretation of basic textbooks for teacher education. In the textbooks, reflection is presented as a good medicine for the professional teacher (...) and a continuous reflection will improve the professional practice by developing consciousness in action. In the conclusion I will present some recommendations on how to improve the understanding and use of reflection. My main goal is to provide reflection with a theoretical content and a clearer direction. Reflection is a knowledge searching, which is not based on experience and facts, but which is closely tied to philosophical thinking, critical theory and the ability to develop an overview. (shrink)

The purpose of this paper is to reflect on how the Corona pandemic might influence human understanding of our position of being in the world. In the first part of the paper, we present how a pandemic can be under- stood in relation to our society and our educational system. Then, we will present problems and questions highlighted by the pandemic and the kind of transformations needed to address these problems. The core ele- ments that require transformation are the understanding (...) of the essence of man or the human condition, the understanding of what caring for nature and even a pandemic means, and how to measure human action and values.

This essay is an attempt to participate in a discussion about metaphysics today. I claim that metaphysic now seems silenced or taken for granted. Machiavelli’s idea of fortuna or fate represents question and perception that cannot be recognized empirically. My aim is to place Machiavelli into an ongoing discussion about the distinction between nature and culture and perception of reality as organic or harmonic. As part of this, I will discuss fortuna’s place in modern research based teacher education, which places (...) our fate in the hand of science, the institutionalization of learning and the lack of virtue. In conclusion, I wish to express some critical remarks on this development, not taking into account the metaphysical speculation. (shrink)

This paper offers an alternative view of spacetime different from both substantivalism and relationism. Using basic ideas underlying the fiber bundle formulation of field theories, it illustrates the function of spacetime in individuating local fields. As the system of numerical identities for entities that we can individually refer to, spacetime is an intrinsic, indispensable, and inalienable structure of the physical world with distinct entities.

Background: Financial conflict of interest in clinical research is an area of active debate. While data exist on the perspectives and roles of academic institutions, investigators, industry sponsors, and scientific journals, little is known about the perspectives of potential research participants.Methods: The authors surveyed potential research participants over the internet, using the Harris Interactive Chronic Illness Database. A potential research participant was defined by: self report of diagnosis by a health care professional and willingness to participate in clinical trials. Email (...) invitations were sent to 20 205 persons with coronary artery disease, breast cancer, or depression; a total of 6363 persons were screened; of these, 86% or 5478 met inclusion criteria and completed the survey. The outcome measures were respondents’ ratings on: importance of knowing conflict of interest information, whether its disclosure ought to be required, and its effect on willingness to participate—across seven widely discussed scenarios of financial conflicts of interest .Results: Majority responded that knowing conflict of interest information was “extremely” or “very” important; a larger majority felt financial conflicts of interest should be disclosed as part of informed consent . In all seven scenarios, a majority was still willing to participate but in some scenarios a sizable minority would be wary of participation. Respondents were more wary of individual than institutional conflicts of interest. Illness group and sociodemographic factors had modest effects and did not affect the main trends.Conclusions: The prevailing practice of non-disclosure of financial conflicts of interest in clinical research appears contrary to the values of potential research participants.

Subjects enrolled in studies testing high risk interventions for incurable or progressive brain diseases may be vulnerable to deficiencies in informed consent, such as the therapeutic misconception. However, the definition and measurement of the therapeutic misconception is a subject of continuing debate. Our qualitative pilot study of persons enrolled in a phase I trial of gene transfer for Parkinson disease suggests potential avenues for both measuring and preventing the therapeutic misconception. Building on earlier literature on the topic, we developed and (...) tested an interview guide that focuses on how the subjects decided to participate, emphasizing the integration of subjects’ various statements that are relevant to assessing the therapeutic misconception, rather than evaluating them as isolated statements. The results indicate that a subject’s understanding of the purpose of research is best explored in juxtaposition to the subject’s motivation for participating. (shrink)

I identify three functions of language: the communicative, the objectifying, and the objective. I claim that of these three functions, the objective function is the most essential, in the sense specified in the paper, and the communicative the least. I further indicate that language use without the communicative function is more prevalent than might commonly be believed.

Det er eit uttalt mål å gjøre grunnskulelærarutdanninga forskingsbasert. I det dominerande tankemønsteret i grunnskulelærarutdanninga er det konstruert ei motsetning mellom vitskapleg kunnskap og erfaringskunnskap. Vitskapleg kunnskap vert skildra som noko positivt, medan erfaringskunnskap får ei negativ omtale. Dette filosofiske essayet vil framskrive ei re-oppfatning av denne dikotomien. Målet med arbeidet er å redusere dikotomien mellom desse to kunnskapsformene og vise ei forståing som er meir jambyrdig, og som samlande kan bli kalla for lærarens levande kunnskap. Teorien om levande kunnskap (...) tar utgangpunkt i mennesket si heilskapande erkjenningsevne. Mennesket sin kognitive kapasitet inneheld både rasjonelle, etiske, emosjonelle og motoriske erkjenningar. Eit avgjørande aspekt med den levande kunnskapen er lærarens etiske- emosjonelle kunnskap og sensibilitet i tillegg til den logisk rasjonelle evna. (shrink)

Let n ≥ 3 be an integer. We show that it is consistent that every σ1n-set of reals is universally Baire yet there is a projective well-ordering of the reals. The proof uses “David’s trick” in the presence of inner models with strong cardinals.

Although the teaching of medical ethics and law in medical education is an old story that has been told many times in medical literature, recent studies show that medical students and physicians lack confidence when faced with ethical dilemmas and medico-legal issues. The adverse events rates and medical lawsuits are on the rise whereas many medical errors are mostly due to negligence or malpractices which are preventable. While it is true that many medical schools teach their students medical law and (...) ethics, there are wide variations in what is being taught because there is no universally agreed syllabus. Yet the knowledge of medical law and ethics is closely relevant to the medical profession and that failure in abiding the law may result in serious civil or even criminal consequences. While this paper does not propose to lay detailed analysis of the relevant areas of law or ethics, it proposes to cover some legal areas so as to highlight and bring to attention the need for a medical law and ethics course. This article also considers the problems faced and recommendation as to future directions to be taken with respect to teaching medical law and ethics. It concludes with a suggested course outline for the teaching of medical law and ethics. (shrink)

The purpose of this study is to explore the emotional dimension of the student-teachers’ experiences, which is marked by anxiety. This study is based on a combination of a phenomenological informed theoretical framework and a phenomenographic approach. The empirical material refers to in-depth interviews with student-teachers. Through an abductive analysis of the material, anxiety experiences appeared to be a significant matter in the student teachers’ emotional life. Our study showed that anxiety in different variations to a large extent characterized the (...) emotional dimension of the student teachers’ experiences. The variations were expressed through three overarching categories of anxiety. The first category of anxiety is about losing one’s dignity, the second about not being recognized as a person, and the third about doing something very wrong. To operationalize the purpose of this study, we will discuss the importance of considering anxiety experiences as a didactical content component in teacher education. (shrink)

America has poured about 200 billion dollars into cancer research since President Nixon declared war on cancer in 1971. How is the war going after three decades? Why do assessments vary as widely as “beating cancer” and “loosing the war on cancer?”.
