Stuttering is one of the most well-known speech disorders, but the underlying neurological mechanisms are debated. In addition to genetic factors there are also major non-genetic contributions. It is here proposed that infection with group A beta-hemolytic streptococcus (GAS) was a major underlying cause of stuttering until the mid 1900s, when penicillin was introduced for the treatment of streptococcal infections about 1946. The main mechanism proposed is an autoimmune reaction from tonsillitis, targeting specific molecules, for example within the basal ganglia. (...) It is here also proposed that GAS infections may have continued to cause stuttering to some extent, to the present date, though more rarely. If so, early diagnosis of such cases would be of importance. Childhood cases with sudden onset of stuttering after throat infection may be particularly important to assess for possible GAS infection. The support for this hypothesis primarily comes from three lines of argument. First, medical record data from the 1930s strongly indicates that there was one type of medical event in particular that preceded the onset of childhood stuttering with unexpected frequency: diseases related to GAS throat infections. In particular, this included tonsillitis and scarlet fever, but also rheumatic fever. Rheumatic fever is a childhood autoimmune sequela of GAS infection, which was a relatively widespread medical problem until the early 1960s. Secondly, available reports of changes of the childhood prevalence of stuttering indicates striking parallels between stuttering and the incidence of rheumatic fever, with (1) decline from the early 1900s, (2) marked decline from the introduction of penicillin about 1946, and (3) reaching a more stable level in the 1960s. The correlations between the data for stuttering and for rheumatic fever after introduction of penicillin are very high, at about 0.95. Thirdly, there are established biological mechanisms linking GAS tonsillitis to immunological effects on the brain. In addition, a small number of more recent case reports have provided further support for the hypothesis linking stuttering to GAS infection. Overall, it is proposed that the available data provides strong evidence for the hypothesis that GAS infection was a major cause of stuttering until the mid 1900s. (shrink)

Stuttering is a disorder characterized by intermittent loss of volitional control of speech movements. This hypothesis and theory article focuses on the proposal that stuttering may be related to an impairment of the energy supply to neurons. Findings from electroencephalography, brain imaging, genetics, and biochemistry are reviewed: Analyses of the EEG spectra at rest have repeatedly reported reduced power in the beta band, which is compatible with indications of reduced metabolism. Studies of the absolute level of regional cerebral blood flow (...) show conflicting findings, with two studies reporting reduced rCBF in the frontal lobe, and two studies, based on a different method, reporting no group differences. This contradiction has not yet been resolved. The pattern of reduction in the studies reporting reduced rCBF corresponds to the regional pattern of the glycolytic index. High regional GI indicates high reliance on non-oxidative metabolism, i.e., glycolysis. Variants of the gene ARNT2 have been associated with stuttering. This gene is primarily expressed in the brain, with a pattern roughly corresponding to the pattern of regional GI. A central function of the ARNT2 protein is to act as one part of a sensor system indicating low levels of oxygen in brain tissue and to activate appropriate responses, including activation of glycolysis. It has been established that genes related to the functions of the lysosomes are implicated in some cases of stuttering. It is possible that these gene variants result in a reduced peak rate of energy supply to neurons. Lastly, there are indications of interactions between the metabolic system and the dopamine system: for example, it is known that acute hypoxia results in an elevated tonic level of dopamine in the synapses. Will mild chronic limitations of energy supply also result in elevated levels of dopamine? The indications of such interaction effects suggest that the metabolic theory of stuttering should be explored in parallel with the exploration of the dopaminergic theory. (shrink)

Dance events as a caregiver intervention for persons with dementiaThe aim of the study was to illuminate the phenomenon of dance events as a caregiver intervention for persons with dementia in one nursing home as described by the caregivers. Seven caregivers were interviewed. The interviews were unstructured and conducted while the caregivers were watching a video of dance events arranged in the nursing home. The analysis was carried out using the phenomenological method developed by Giorgi. The results are presented in (...) five consistent themes: (1) prerequisites for dance events; (2) creating and preparing different kinds of activities related to the dance events; (3) emotional arousal; (4) caregivers’ situational understanding; and (5) dance events and contextual consequences and synthesis into a general structure. The meaning of the dance events as a caregiver intervention was founded not only on the dancing itself but also encompassed the ontological state of ‘being together’. (shrink)

Personalism is understood today as the name of an important current in twentieth-century thought which, inspired by the Christian and humanistic traditions of the West, has sought to deepen our understanding of the meaning and value of human personhood. Opposing both individualism and collectivism, personalism has stressed the uniqueness of each person, the meaning and value of interpersonal relations, and the unity that holds persons together and is, ultimately, also personal in itself: the person of God. Personalism's insights into the (...) nature of personhood have broad implications for our view of ethics, politics, education, and religion. The history of personalism has, however, been poorly understood. Jan Olof Bengtsson shows that personalism began as early as the eighteenth century and was a central, international current of thought throughout the nineteenth century - that it was, in fact, more characteristic of the nineteenth century than of the twentieth.

Within child and adolescent psychiatry, there are a number of potential dilemmas pertaining to diagnosis, treatment, the protection of the child, as well as the child's own developing intelligence and moral judgement. Diagnostic Dilemmas in Child and Adolescent Psychiatry is the first in the IPPP series to explore this highly complex topic.

It has been argued amply that alternative theoretical approaches to the corporate governance phenomenon can be a valuable complement to the mainstream economic approach. However, such approaches are largely embryonic and empirical studies based on more organisationally oriented theory are few and geographically limited. The purpose of the present article is to discuss the value of organisationally oriented approaches to corporate governance as a complement to more traditional economic approaches. This is accomplished by discussing the findings of an empirical study (...) on Swedish shareholder activism in the light of institutional sociology. The study demonstrates how the preferences and actions of investors are institutionally determined, and not only influenced by regulation and law, but also by moral obligations, societal expectations and relational ties. Thus, the study demonstrates the value of complementing economic explanations with more institutionally and organisationally oriented accounts, in order to better understand shareholder activism in particular, and corporate governance in general.

This article contributes to the literature on national varieties of socially responsible investment (SRI) by demonstrating how Scandinavian SRI developed from the 60s and onwards. Combining findings on Scandinavian SRI with insights from previous research and institutional theory, the article accounts for the role of changes in societal values and norms, the mechanisms by which SRI practices spread, and how investors adopt and transform practices to suit their surrounding institutional contexts. Especially, the article draws attention to how different categories of (...) investors act as institutional entrepreneurs during specific historical periods, and how these roles come to shift as institutional rule systems of varying societal levels change. Thus, the insights gained are useful in the future research agenda concerned with advancing knowledge on idiosyncrasies and commonalities of national SRI manifestations, and to understand the reasons underlying such characteristics.

The volume documents, and makes an original contribution to, an astonishing period in twentieth-century philosophy—the progress of Arne Naess's ecophilosophy from its inception to the present. It includes Naess's most crucial polemics with leading thinkers, drawn from sources as diverse as scholarly articles, correspondence, TV interviews and unpublished exchanges. The book testifies to the skeptical and self-correcting aspects of Naess's vision, which has deepened and broadened to include third world and feminist perspectives. Philosophical Dialogues is an essential addition to the (...) literature on environmental philosophy. (shrink)

Drawing general inferences on the basis of single-case and small- n studies is often seen as problematic. This article suggests a logic of generalization based on thinly rationalistic social mechanisms. Ideal-type mechanisms can be derived from empirical observations in one case and, based on the assumption of thin rationality, used as a generalizing bridge to other contexts with similar actor constellations. Thus, the “portability” builds on expectations about similar mechanisms operating in similar contexts. We present the general logic behind such (...) “rationalistic generalization” and relate it to other ideas about generalization from single-case studies. (shrink)

The history of pedagogics gives the impression that pedagogics has never had an identity of its own. Throughout history it has borrowed its identity from philosophy, theology, psychology and sociology. Against the background of this historical challenge, the article proposes pedagogical practice as an alternative identity to pedagogics, although not in the classical sense of an absolute and self‐sufficient identity, and it develops one particular ontological theory of pedagogical practice viewed from a life‐world approach with the ambition of suggesting a (...) theoretical point of departure for pedagogical research.

This article is intended as a brief introduction to the lifeworld approach to empirical research in education. One decisive feature of this approach is the inclusion of an explicit discussion of its ontological assumptions in the research design. This does not yet belong to the routines of empirical research in education. Some methodological consequences of taking the lifeworld ontology as a ground for empirical research are discussed as well as the importance of creativity in the choice of method for particular (...) projects. In this way, the lifeworld approach has its own particular perspective in phenomenological, empirical research in education. The article concludes with a description of an empirical study based on the lifeworld approach in order to illuminate the possibilities for empirical research in education as well as the significance of this approach for education.

The simple concept of a SIC poses a very deep problem in algebraic number theory, as soon as the dimension of Hilbert space exceeds three. A detailed description of the simplest possible example is given.

The core function of argumentation in a democratic setting must be to constitute a modality for citizens to engage differences of opinion constructively – for the present but also in future exchanges. To enable this function requires acceptance of the basic conditions of public debate: that consensus is often an illusory goal which should be replaced by better mastery of living with dissent and compromise. Furthermore, it calls for an understanding of the complexity of real-life public debate which is an (...) intermixture of claims of fact, definition, value, and policy, each of which calls for an awareness of the greater ‘debate environment’ of which particular deliberative exchanges are part. We introduce a rhetorical meta-norm as an evaluation criterion for public debate. In continuation of previous scholarship concerned with how to create room for differences of opinion and how to foster a sustainable debate culture, we work from a civically oriented conception of rhetoric. This conception is less instrumental and more concerned with the role of communication in public life and the maintenance of the democratic state. A rhetorical meta-norm of public argumentation is useful when evaluating public argumentation – not as the only norm, but integrated with specific norms from rhetoric, pragma-dialectics, and formal logic. We contextualise our claims through an example of authentic contemporary public argumentation: a debate over a biogas generator in rural Denmark. (shrink)

This volume collects nine essays that investigate the work of Gottlob Frege. The contributors address Frege’s work in relation to literature and fiction (Dichtung), the humanities (Geisteswissenschaften), and science (Wissenschaft). Overall, the essays consider internal connections between different aspects of Frege’s work while acknowledging the importance of its philosophical context. There are also further common strands between the papers, such as the relation between Frege’s and Wittgenstein’s approaches to philosophical investigations, the relation between Frege and Kant, and the place of (...) Frege’s work in the philosophical landscape more generally. The volume is therefore of direct relevance to several current debates in philosophy in general, in addition to Frege and Wittgenstein research in particular. Even though Frege’s great significance for contemporary philosophy is not disputed, the question of how we are to understand the character and aims of his project is debated. The debate has a starting point in Frege’s specific conception of logic. The volume elucidates this conception as well as the relation between natural language and the Begriffsschrift. It will help philosophers, researchers, and students better understand the nuances of this great thinker. By extension, it will also help readers seeking to understand Wittgenstein’s approach to philosophical difficulties and his struggle to find an apt form of presentation for his philosophical investigations.

High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)

The problem of constructing maximal equiangular tight frames or SICs was raised by Zauner in 1998. Four years ago it was realized that the problem is closely connected to a major open problem in number theory. We discuss why such a connection was perhaps to be expected, and give a simplified sketch of some developments that have taken place in the past 4 years. The aim, so far unfulfilled, is to prove existence of SICs in an infinite sequence of dimensions.

As a philosopher rather than a historian, Phillip Ferreira tends naturally, in his article in this issue of The Pluralist, "On the Imperviousness of Persons," as in his first one on The Worldview of Personalism, to place the emphasis quite as much on the general philosophical issues as on the specific historical interpretation of Pringle-Pattison. But this emphasis was from the beginning invited by my own assessment of Pringle-Pattison. I will continue here to answer Ferreira to a considerable extent in (...) its terms, but, as a historian rather than a philosopher, I will try to use arguments which, based on my historical knowledge of them, I think would have been those of Pringle-Pattison and the other personal ..

The pathway from scientific knowledge (based on data, models, and forecasts) to societal implications and policy advice is a perilous one. The shift from "is" to "ought" may be slippery in terms of climate, biodiversity, regulations, and business. Yet, what is to be done if one's research discloses that fellow humans are unwittingly carrying out destructive actions on a large scale? If they are unaware of the dynamics within which they are (or are in danger of becoming) imprisoned, is there (...) then not an ethical obligation to respond beyond the scope of one's given role? This dilemma lies at the core of the issue of science-based activism, which the life and work of Jorgen Randers in many ways epitomizes. The best means of understanding science-based activism can be found in exploring Randers' steps, as this festschrift does. [Jorgen Randers (born 1945) co-authored The Limits to Growth in 1972 and its sequels in 1992 and 2004. He is a Professor of Climate Strategy at the Norwegian Business School in Oslo where he works on climate and energy issues, system dynamics, and green growth. Randers was President of the Norwegian Business School/BI 1981-89, and Deputy Director General of WWF International 1994-99.

The relationship between body and mind is a classical ontological problem in the history of philosophy. To this problem can be added an epistemological question about the relationship between body and knowledge. In this article, I will discuss these questions delimited to one central area of education, that is, school. My point of view will be life-world phenomenology and in particular the theory of the lived body.

Reflection seems today to be highest fashion ineducation, especially in discussions aboutteacher education and the teaching profession.This has created the paradoxical situation that reflection is often used in an unreflectedmanner. Furthermore, this discovery ofreflection is not supported by earlierresearch. In philosophy, however, reflectionhas always played a central role.

How do markets come about? This article offers a first systematic analysis of three different ideal types of market fashioning: mutual adjustment, organization, and fields. Although aspects of these are identifiable in most empirical markets, these three ideal types provide analytic tools for students of real markets and marketplaces. After going through this comprehensive literature, it is argued that mutual adjustment, which refers to non-planned processes, is affinity with markets in which products are differentiated, for example, producer markets. Organization refers (...) to process driven by attempts to decide for others and shows affinity with markets for standardized and homogenous products, for example, stock exchanges. Organization also accounts for the making of marketplaces. The broader notion of fields does not refer to any specific process, but accounts for the context of market fashioning and its respective power struggles. (shrink)

Klyachko and coworkers consider an orthogonality graph in the form of a pentagram, and in this way derive a Kochen-Specker inequality for spin 1 systems. In some low-dimensional situations Hilbert spaces are naturally organised, by a magical choice of basis, into SO(N) orbits. Combining these ideas some very elegant results emerge. We give a careful discussion of the pentagram operator, and then show how the pentagram underlies a number of other quantum “paradoxes”, such as that of Hardy.

The article presents and discusses an ongoing fellowship project entitled ‘Space for Interference’, conducted under the Norwegian Programme for Research Fellowships in the Arts. Two concrete site-specific art projects produced under Space for Interference serve as a point of departure for an investigation into methods of interference and the forms of address that artists use when intervening in other specialized fields in society. The institutions that provide the site for an art project have different social functions. We ask what may (...) be their motivation for allowing artists access to their physical environments, apparatuses, procedures, systems and discourses. The fact that the artists’ projects in these contexts function as a means of self-observation for the institutions seems obvious. Nevertheless, we seek to investigate the various economic and political factors that allow these institutions to include potentially critical activities, which aim to modify or transgress their systems, and thereby displaying how they are malleable and mobile bodies. One assertion we make is that by doing so the involved institutions prove to be modern, self-critical and flexible, thus complying with political requirements to adapt to the rapidly changing environments of the information and communication age. The perspective from systems theory in the Luhmannian tradition has proved useful since it shows how the issues of art may also be the problems of science, business, politics and the law in the complex and decentered social universe of today. The issues of contingency, insecurity, paradox and autoreflexivity, surplus meanings and the complexity and decentering of the subject are at the heart of contemporary art. Systems theory provides a way to link such practices theoretically with scientific discourse and with the advanced problem solving and criticality of other social domains, like politics, business and the media industries.

The volume is divided into three parts. The first part takes up (...) classical issues -- the 'positive' and the 'preventive' checks and their determinants -- raised by Malthus himself, and examines the issues against fresh evidence from Europe, America, and Asia. These issues are also themes of the second part, which is devoted to short-term fluctuations in mortality and fertility in relation to prices, wages, and other economic indicators. The final set of chapters is a coherent collection of technically sophisticated articles from an on-going international joint project concerned with how households respond to economic stress in different economic, social, and cultural settings, in traditional China, Japan, Sweden, Belgium, and Italy. With a brief, but well-organized introduction, this collection of scholarly essays offers both demographers and economic historians a wealth of exciting findings and stimulating insights. (shrink)

This paper examines the existential context of physical and mental health. Hans Georg Gadamer and The World Health Organization’s conceptualizations are discussed, and current medicalized and idealized views on health are critically examined. The existential dimension of health is explored in the light of theories of selfhood consisting of different parts, Irvin Yalom’s approach to “ultimate concerns” and Martin Heidegger’s conceptualization of “existentials.” We often become aware of health as an existential concern during times of illness, and health and illness (...) can co-exist. The paper discusses how existential suffering in Western culture is described, to an increasing degree, as disorders or psychological deficits, and perfectionistic health goals easily can become a problem. We seek to avoid suffering rather than relate to it, with all the tension that may create. The paper argues that suffering is an unavoidable aspect of people’s experience of their lives, and actively relating to suffering must be regarded as a fundamental aspect of health. The need and usefulness of a concept of “existential health” is discussed. (shrink)

Entrepreneurs typically live with the ever-present threat of business failure arising from limited financial resources and aggressive competition in the marketplace. Under these circumstances, conflicting priorities arise and the entrepreneur is thus faced with certain dilemmas. In seeking to resolve these, entrepreneurs must often rely on their own judgment to determine “what is right”. There is thus a need for a technique to assist them decide on a course of action when no precedent or obvious solution exists. This research paper (...) examines how entrepreneurs experience and deal with these dilemmas. The research is based on interviews with seven entrepreneurs in established service-oriented ventures, which gave rise to 26 dilemmas. These dilemmas were analyzed by making use of the Synergy Star technique, which is introduced here as a tool that is useful in defining any dilemma, isolating the ethical component, and resolving the dilemma in a way that is congruent with the entrepreneur’s personal world-view.
