Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. Inattentiveness, overactivity, and impulsiveness are presently regarded as the main clinical symptoms. The dynamic developmental behavioral theory is based on the hypothesis that altered dopaminergic function plays a pivotal role by failing to modulate nondopaminergic (primarily glutamate and GABA) signal transmission appropriately. A hypofunctioning mesolimbic dopamine branch produces altered reinforcement of behavior and deficient extinction of previously reinforced behavior. This gives rise to delay (...) aversion, development of hyperactivity in novel situations, impulsiveness, deficient sustained attention, increased behavioral variability, and failure to “inhibit” responses (“disinhibition”). A hypofunctioning mesocortical dopamine branch will cause attention response deficiencies (deficient orienting responses, impaired saccadic eye movements, and poorer attention responses toward a target) and poor behavioral planning (poor executive functions). A hypofunctioning nigrostriatal dopamine branch will cause impaired modulation of motor functions and deficient nondeclarative habit learning and memory. These impairments will give rise to apparent developmental delay, clumsiness, neurological “soft signs,” and a “failure to inhibit” responses when quick reactions are required. Hypofunctioning dopamine branches represent the main individual predispositions in the present theory. The theory predicts that behavior and symptoms in ADHD result from the interplay between individual predispositions and the surroundings. The exact ADHD symptoms at a particular time in life will vary and be influenced by factors having positive or negative effects on symptom development. Altered or deficient learning and motor functions will produce special needs for optimal parenting and societal styles. Medication will to some degree normalize the underlying dopamine dysfunction and reduce the special needs of these children. The theory describes how individual predispositions interact with these conditions to produce behavioral, emotional, and cognitive effects that can turn into relatively stable behavioral patterns. Key Words: catecholamine; clumsiness; dopamine; hyperkinesis; hyperkinetic disorder; impulsivity; monoamine; neuromodulator; overactivity; pollutants; reinforcement; reward; verbally governed behavior; soft signs; variability.

Rudolf Steiner’s work contains many different claims about human freedom spread out in over three hundred books. A basic challenge for the research on Steiner is to create an overview of his idea of freedom, but also to consider potential conflicting claims. One of the main tensions in Steiner’s work is the one between his early philosophical and later anthroposophical accounts of freedom. The former focuses on individual freedom while the latter puts the emphasis on the greater whole in which (...) the human being exists. Hegel’s idea of freedom can be used to create a comprehensive and coherent understanding of Steiner’s different perspectives on freedom. In particular, using Hegel’s notion of being-with-oneself in otherness, the freedom that the individual can experience within the whole can be seen as an immanent development of the individual itself.

Summary This paper examines the second generation of British air pumps, covering the period 1700–1750. The air pump originated in the 1650s and 1660s thanks to the work of Otto von Guericke in Magdeburg, Robert Boyle in Oxford and London, and Accademia del Cimento in Florence. While these first models were often seen as unreliable and temperamental, and available to a small group only, the next period saw the air pump transformed into a publicly accessible device for use in public (...) and private demonstrations, in practical applications, as well as in the production of new knowledge. In England, the instrument maker Francis Hauksbee and his followers played a decisive role in this process, which was connected, among other things, to popular medicine, anatomy and health. In this period, pneumatics (the field of air pumps and air-pump practice) reached a state where the pump came to be regarded as an unproblematic tool; and where a ‘vacuum’ came to be thought of and handled as an object.

Translators as members of a certain culture, generally that of the target culture, base their translation-relevant decisions on their own culture, while the decisions are motivated by the source culture. In the translation process, cultural differences may lead to various decision-making conflicts and the translator has to find a compromise between the author of the source text, the target recipient and finally, of course, the translator him/herself. In this article, proceeding from functionalist approaches to translation, the discussion focuses on the (...) decision conflicts related to translating culturespecific elements. Culture-related decision conflicts, as considered here, refer to the translator's inner indecision with reference to his/her goals, interests, values, beliefs, methodological approach, or any consequences thereof, attributable to the different cultural embeddings of the source text and the target text. In general, decision conflicts are perceived as subjective translation problems. The translator has to be able to constantly act between separate perspectives, continuously see things from different viewpoints. The conflicts arise when the translator attempts to bring together two incongruent cultures without prejudice to any of the parties involved in the process. Acting within the interface of two different cultures, bearing in mind the interests of several participants, is what makes translation-relevant decisions a highly complex matter. (shrink)

There are basically two ways to view intuitionistic logic: as a philosophical‐foundational issue in mathematics; or as a technical discipline within mathematical logic. Considering first the philosophical aspects, for they will provide the motivation for the subject, this chapter follows L. E. J. Brouwer, the founding father of intuitionism. Although Brouwer himself contributed little to intuitionistic logic as seen from textbooks and papers, he did point the way for his successors.

Neoliberal educational reforms include extensive use of standardized tests. We examine the Program for International Student Assessment (PISA) initiated and developed by the Organization for Economic Cooperation and Development (OECD). Examining previous research on teachers’ reactions to neoliberal reforms altering their work context, we have identified three theoretical frameworks in use: labour process theory, derived from structural Marxism; post-structuralism, relying primarily on Foucault’s conceptualizations; and ‘new professionalism’, which has emerged from the theory of professions. A major weakness in these frameworks (...) is their inability to account for different reactions to the same structural and cultural conditions. Therefore, we suggest utilizing Archer’s theories of reflexivity and reflexive modes to understand these reactions. Presenting one Norwegian lower secondary school teacher’s reflexive engagement with PISA in the Norwegian school context as an example, our mixed methods case study indicates autonomous reflexivity as the prevailing mode. Meta-reflexivity rates second in prevalence. (shrink)

From the reviews: "A good textbook can improve a lecture course enormously, especially when the material of the lecture includes many technical details. Van Dalen's book, the success and popularity of which may be suspected from this steady interest in it, contains a thorough introduction to elementary classical logic in a relaxed way, suitable for mathematics students who just want to get to know logic. The presentation always points out the connections of logic to other parts of mathematics. The (...) reader immediately see the logic is "just another branch of mathematics" and not something more sacred." Acta Scientiarum Mathematicarum, Hungary. (shrink)

This article presents and discusses the method of micro-phenomenological self-inquiry. Micro-phenomenology is usually performed with two persons, one interviewer and one interviewee. Micro-phenomenological self-inquiry consists of one person investigating their own experience. The different aspects of the regular micro-phenomenological interview are reviewed in relation to the process of self-inquiry. Examples of recent studies that apply micro-phenomenological self-inquiry are presented. Finally, there is a discussion of some methodological problems and objections. Advantages and disadvantages of micro-phenomenological self-inquiry are considered. Suggestions are given (...) for what kind of research and research contexts that micro-phenomenological self-inquiry may be particularly suitable for. (shrink)

In Hegel’s Conception of the Determinate Negation , Terje Sparby develops a comprehensive account of the three forms of the determinate negation in Hegel’s philosophy.

Until recently, only two Arabic translations of Ptolemy’s Almagest were thought to have survived, one by al-Ḥajjāj made under the caliph al-Maʾmūn and one by Isḥāq b. Ḥunayn, later revised by Thābit b. Qurra, prepared in the second half of the third/ninth century. In the 2010s, a third Arabic version of the Almagest, authored by Thābit b. Qurra alone, was first shown by Dirk Grupe to be extant in a partial Latin translation in a Dresden manuscript, and then in an (...) Arabic manuscript in Jaipur that breaks off after chapter VI.2. We introduce here a second manuscript of this Thābit version, extant in the Khuda Bakhsh Library in Patna, which is around four centuries older than the Jaipur manuscript, was copied from a manuscript by the hand of al-Bīrūnī, and extends the text till the middle of Book VIII. After a general introduction, we provide a detailed description of this manuscript. (shrink)

This chapter contains sections titled: Logic: The Proof Interpretation Analysis: Choice Sequences Further Semantics.

Background: Textbooks are central for the education of professionals in the health field and a resource for practitioners already in the field. Objectives: This article focuses on how 12 textbooks in psychiatric nursing and psychiatry, published in Norway between 1877 and 2012, describe and present people with psychosis. Research design: We used qualitative content analysis. Ethical considerations: The topic is published textbooks, made available to be read by students, teachers and professionals, and no ethical approval was required. Findings: The analysis (...) shows that all 12 textbooks describe and present people who are considered as psychotic from a ‘perspective from above’. In this perspective, the readers are learning about psychosis in the professional’s language and from the author’s viewpoint. Most often the textbooks communicate a universal image of people with psychosis, a description that fits with the diagnostic criteria. The analysis also shows that two textbooks in psychiatric nursing combined this perspective with a ‘perspective from within’. Here, the readers are learning about psychosis from the patients’ own viewpoint. The authors communicate a personal, psychotic universe that differs from various people, even if they have the same diagnosis, and the descriptions are focusing on the patient as a whole person. Discussion and conclusion: Drawing partly on Rita Charon’s writings about narrative knowledge in the health field, and partly on insights from Martha Nussbaum and her concept of narrative imagination, we argue that mental health professionals need to learn about, understand and fathom what patients go through by reading, listening to and acknowledging the patients’ own stories and experiences. Cultivating the capacity for empathy and compassion are at the very heart of moral performance in the mental health field. A valuable moral resource in that regard is leading textbooks and how they describe and present people with severe mental illness. (shrink)

It is the aim of this article to identify possible sources of additional texts for October in the many Slavonic copies of the October menologion, and also to show how the pre-metaphrastic Byzantine October menologion once might have looked, based on the evidence of the Slavonic translated menologia.

Translators as members of a certain culture, generally that of the target culture, base their translation-relevant decisions on their own culture, while the decisions are motivated by the (alien) source culture. In the translation process, cultural differences may lead to various decision-making conflicts and the translator has to find a compromise between the author of the source text, the target recipient and finally, of course, the translator him/herself. In this article, proceeding from functionalist approaches to translation, the discussion focuses on (...) the decision conflicts related to translating culturespecific elements. Culture-related decision conflicts, as considered here, refer to the translator’s inner indecision with reference to his/her goals, interests, values, beliefs, methodological approach, or any consequences thereof, attributable to the different cultural embeddings of the source text and the target text. In general, decision conflicts are perceived as subjective translation problems.

Classifying different meditation techniques is essential for the progress of meditation research, as this will enable discerning which effects are associated with which techniques, in addition to supporting the development of increasingly effective and efficient meditation-based training programs and clinical interventions. However, both the task of defining meditation itself, as well as defining specific techniques, faces many fundamental challenges. Here we describe problems involved in this endeavor and suggest an integrated model for defining meditation. For classifying different meditation techniques, we (...) draw on classical, contemporary, and holistic systems of classification. We analyze different techniques and propose that all meditation techniques are based on a specific set of activities, that is: focusing, releasing, imagining, and moving in relation to an object of meditation, including fields of experience. Meditative activities can be combined and unified in the activities of observing, producing, and being aware. All meditative activities are unified in awareness of awareness. Defining specific meditation techniques may be done by specifying which activities and objects are involved. The advantage of our approach is that it can potentially account for the inner workings of all current systems of classification and hence it lays the foundation for formulating an overarching system of meditation that can guide future research and practice.

In Norway, research ethics committees in medicine are organized as interdisciplinary regional committees. Since 1999, Norway requires that one member of each ethics committee be a psychologist. Competence in psychology is considered relevant not only when evaluating psychology projects. As discussed in this article, a competence in psychology is also relevant for evaluating a number of issues common to all research involving human subjects as well as in the evaluation of protocols where other professionals have employed psychological methodologies.

Beth models of analysis are used in model theoretic proofs of the disjunction and (numerical) existence property. By glueing strings of models one obtains a model that combines the properties of the given models. The method asks for a common generalization of Kripke and Beth models. The proof is carried out in intuitionistic analysis plus Markov's Principle. The main new feature is the external use of intuitionistic principles to prove their own preservation under glueing.

Digital texts have for decades been a challenge for reading research, creating a range of questions about reading and a need for new theories and concepts. In this paper, we focus on materialities of texts and suggest an embodied, enacted, and extended approach to the research on digital reading. We refer to findings showing that cognitive activities in reading are grounded in bodily and social experiences, and we explore the cognitive role of the body in reading, claiming that–influenced by tacit (...) knowledge and the task at hand–textual meaning is enacted through a mental and physical engagement with text. Further, applying the concept of affordances, we examine how digital technologies have induced new ways of physically handling and mentally interpreting text, indicating that brain, body, text, and technologies are integrated parts of an extended process of reading. The aim of the paper is to encourage empirical research on the interplay between body, text, and text materialities, a focus we argue will deepen our understand of the current transformation of reading.

The article depicts the traditional fishing, the outdoor drying of Stockfish, and its cultural and culinary uses in a historic context and today. The fishing of the North East Arctic cod (Gadus morhua) is a sustainable coastal fishery for millennia in the North of Norway, but climate change challenges the outdoor drying of stockfish. The article follows the stockfish history during the hanseatic office in Bergen until the present trade. The early commercial production of stockfish was due to urban expansion, (...) fasting rules and the need to provide nutritious food to the poor in Northern Europe and beyond. The article follows the traces of stockfish expansion as a staple food, first to Northern Europe, later to central Europe and the Mediterranean countries, before ending up as an important food supply to West-African countries in the nineteenth century. The article explains the early Greek and Renaissance concerns for eating fish and for stockfish in particular due to dietetic and medical beliefs. Then the cultural impact of stockfish is explained by showing some examples of both living and disappearing culinary traditions. The use of lye for soaking stockfish is not only a Scandinavian tradition but a little known shared European craft and culinary practice. Battering the stockfish with a wooden hammer, the use of lye for durability and water for softening the hard fish texture was practiced for preparing stockfish. Finally, the article touches upon rules, regulations and organisations that can help strengthening and preserve the traditional craft and culinary uses of stockfish today. (shrink)

Although the main responsibility for informed consent of medical procedures rests with doctors, nurses’ roles are also important, especially as patient advocates. Nurses’ preparation for this role in settings with a hierarchical and communal culture has received little attention. We explored the views of hospital managers and nurses regarding the roles of nurses in informed consent and factors influencing these roles. We conducted a qualitative study in a private, multispecialty hospital in Indonesia. Semi-structured interviews were conducted with seven managers. Two (...) rounds of focus group discussions with nurses (n = 27) were conducted. Constant comparative approach was used in the analysis. Nurses can act as manager, witness, information giver, and advocate in the informed consent process. These roles are influenced by nurses’ preparedness, hospital culture and policy, patients’ understanding, family involvement, and cost-related issues. In preparation for these tasks, nurses should acquire communication skills, clinical knowledge, and legal and ethical knowledge. (shrink)

Dedicated to Dana Scott on his sixtieth birthday.It is common knowledge that for a short while Hermann Weyl joined Brouwer in his pursuit of a revision of mathematics according to intuitionistic principles. There is, however, little in the literature that sheds light on Weyl's role and in particular on Brouwer's reaction to Weyl's allegiance to the cause of intuitionism. This short episode certainly raises a number of questions: what made Weyl give up his own program, spelled out in “Das Kontinuum”, (...) how did Weyl come to be so well-informed about Brouwer's new intuitionism, in what respect did Weyl's intuitionism differ from Brouwer's intuitionism, what did Brouwer think of Weyl's views,…? To some of these questions at least partial answers can be put forward on the basis of some of the available correspondence and notes. The present paper will concentrate mostly on the historical issues of the intuitionistic episode in Weyl's career.Weyl entered the foundational controversy with a bang in 1920 with his sensational paper “On the new foundational crisis in mathematics”. He had already made a name for himself in the foundations of mathematics in 1918 with his monograph “The Continuum” [18]; this contained in addition to a technical logical-mathematical construction of the continuum, a fairly extensive discussion of the shortcomings of the traditional construction of the continuum on the basis of arbitrary—and hence also impredicative—Dedekind cuts.

On October 4, 1937, Zermelo composed a small note entitled “Der Relativismus in der Mengenlehre und der sogenannte Skolemsche Satz” in which he gives a refutation of “Skolem's paradox”, i.e., the fact that Zermelo-Fraenkel set theory—guaranteeing the existence of uncountably many sets—has a countable model. Compared with what he wished to disprove, the argument fails. However, at a second glance, it strongly documents his view of mathematics as based on a world of objects that could only be grasped adequately by (...) infinitary means. So the refutation might serve as a final clue to his epistemological credo.Whereas the Skolem paradox was to raise a lot of concern in the twenties and the early thirties, it seemed to have been settled by the time Zermelo wrote his paper, namely in favour of Skolem's approach, thus also accepting the noncategoricity and incompleteness of the first-order axiom systems. So the paper might be considered a late-comer in a community of logicians and set theorists who mainly followed finitary conceptions, in particular emphasizing the role of first-order logic. However, Zermelo never shared this viewpoint: In his first letter to Gödel of September 21, 1931, he had written that the Skolem paradox rested on the erroneous assumption that every mathematically definable notion should be expressible by a finite combination of signs, whereas a reasonable metamathematics would only be possible after this “finitistic prejudice” would have been overcome, “a task I have made my particular duty”.

Volume 1 of this biography of L. E. J. Brouwer was published in 1999.1 The volume under review here covers the period from the early nineteen twenties until Brouwer's death in 1966. It also includes a short epilogue that discusses the disposition of Brouwer's estate after his death, his influence on others, the paths of some of his students and colleagues, and other matters. Van Dalen notes in the Preface that in preparing this volume he consulted some historical studies (...) that appeared after the first volume was published. He also used new material from various archives. The biography contains interesting quotations from unpublished materials in the Brouwer Archive and from correspondence. The bibliographical references to Brouwer's publications, it should be noted, are somewhat different in this volume. This volume, like the first, contains some nice photographs and reproductions. I noted that there were many typographical errors in the earlier book but Volume 2 is relatively free of them.As is the case in Volume 1, the discussion of Brouwer's mathematical and philosophical work is woven into the narrative of Brouwer's life and times. The story in this volume starts with Brouwer's first contacts with Paul Alexandrov and Paul Urysohn in 1923. The interaction began when Urysohn announced that he had found a mistake in Brouwer's definition of dimension in Brouwer's 1913 paper on natural dimension. Was it just a slip of the pen, as Brouwer always maintained, or something more substantial? Urysohn and Alexandrov ultimately came to agree with Brouwer on the matter, and Urysohn was prepared to grant Brouwer priority for the definition of dimension. There were, however, ups and downs along the way. Karl Menger, through his own work in topology and dimension theory, soon got into the picture, and Brouwer and Menger were to …. (shrink)

Brouwer and Weyl recognized that the intuitive continuum requires a mathematical analysis of a kind that set theory is not able to provide. As an alternative, Brouwer introduced choice sequences. We first describe the features of the intuitive continuum that prompted this development, focusing in particular on the flow of internal time as described in Husserl's phenomenology. Then we look at choice sequences and their logic. Finally, we investigate the differences between Brouwer and Weyl, and argue that Weyl's conception of (...) choice sequences is defective on several counts. (shrink)

Dirk van Dalen’s biography studies the fascinating life of the famous Dutch mathematician and philosopher Luitzen Egbertus Jan Brouwer. Brouwer belonged to a special class of genius; complex and often controversial and gifted with a deep intuition, he had an unparalleled access to the secrets and intricacies of mathematics. Most mathematicians remember L.E.J. Brouwer from his scientific breakthroughs in the young subject of topology and for the famous Brouwer fixed point theorem. Brouwer’s main interest, however, was in the foundation (...) of mathematics which led him to introduce, and then consolidate, constructive methods under the name ‘intuitionism’. This made him one of the main protagonists in the ‘foundation crisis’ of mathematics. As a confirmed internationalist, he also got entangled in the interbellum struggle for the ending of the boycott of German and Austrian scientists. This time during the twentieth century was turbulent; nationalist resentment and friction between formalism and intuitionism led to the Mathematische Annalen conflict. It was here that Brouwer played a pivotal role. The present biography is an updated revision of the earlier two volume biography in one single book. It appeals to mathematicians and anybody interested in the history of mathematics in the first half of the twentieth century. (shrink)
