The paper presents two empirical cases of expert musicians—a classical string quartet and a solo, free improvisation saxophonist—to analyze the explanatory power and reach of theories in the field of expertise studies and joint action. We argue that neither the positions stressing top-down capacities of prediction, planning or perspective-taking, nor those emphasizing bottom-up embodied processes of entrainment, motor-responses and emotional sharing can do justice to the empirical material. We then turn to hybrid theories in the expertise debate and interactionist accounts (...) of cognition. Attempting to strengthen and extend them, we offer ‘Arch’: an overarching conception of musical interaction as an externalized, cognitive scaffold that encompasses high and low-level cognition, internal and external processes, as well as the shared normative space including the musical materials in which the musicians perform. In other words, ‘Arch’ proposes interaction as a multivariate multimodal overarching scaffold necessary to explain not only cases of joint performance, but equally of solo improvisation. (shrink)

ICAP is a theory of active learning that differentiates students’ engagement based on their behaviors. ICAP postulates that Interactive engagement, demonstrated by co‐generative collaborative behaviors, is superior for learning to Constructive engagement, indicated by generative behaviors. Both kinds of engagement exceed the benefits of Active or Passive engagement, marked by manipulative and attentive behaviors, respectively. This paper discusses a 5‐year project that attempted to translate ICAP into a theory of instruction using five successive measures: (a) teachers’ understanding of ICAP after (...) completing an online module, (b) their success at designing lesson plans using different ICAP modes, (c) fidelity of teachers’ classroom implementation, (d) modes of students’ enacted behaviors, and (e) students’ learning outcomes. Although teachers had minimal success in designing Constructive and Interactive activities, students nevertheless learned significantly more in the context of Constructive than Active activities. We discuss reasons for teachers’ overall difficulty in designing and eliciting Interactive engagement. (shrink)

The Autism Spectrum Disorder (ASD) represents a set of life-long disorders. In particular, subjects with ASD can display momentary behaviors of acute agitation and aggressiveness called crisis behaviors. These events are problematic for the subject and care providers but little is known about their occurrence, namely, possible relations among intensity, frequency, and duration. A group of ASD subjects (n=33) has been observed for 12 months reporting data on each crisis ( n = 1137 crises). Statistical analysis did not find significant (...) results, while the relation between crisis duration and frequency showed a good fit to a “power law” curve, suggesting the application of Self-Organized Criticality (SOC) model. The SOC is used to describe natural phenomena as earthquakes, bank failures of rivers, mass extinctions, and other systems where a type of “catastrophic events” is necessary to maintain a critical equilibrium. In a sense, subjects at risk of crisis behavior seem to fit the same model as seismic zones at risk of earthquakes. The employment of the same strategies, as those successfully developed for known SOC systems, could lead to important insights for ASD management. Moreover, the SOC model offers possible interpretations of crisis behavior dynamics suggesting that they are unpredictable and, in a sense, necessary. (shrink)

In recent years, there has been an increasing interest in the development of well-founded conceptual models for Service Management, Accounting Information Systems and Financial Reporting. Economic ex- changes are a central notion in these areas and they occupy a prominent position in frameworks such as the Resource-Event Action (REA) ISO Standard, service core ontologies (e.g., UFO-S) as well as financial stan- dards (e.g. OMG’s Financial Industry Business Ontology - FIBO). We present a core ontology for economic exchanges inspired by a (...) recent view on this phenomenon. According to this view, economic exchanges are based on an agreement on the actions that the agents are committed to perform. This view enables a unified treatment of economic exchanges, regardless the object of the transaction. We ground our core ontology on the Unified Foundational Ontology (UFO), discussing its formal and conceptual aspects, instantiating it as a reusable OntoUML model, and confronting it with the REA standard and the UFO-S service ontology.

Receptor‐mediated stimulation induces massive actin polymerization and cyto‐skeletal reorganization. The activity of a potent actin‐modulating protein, gelsolin, is regulated both by Ca2+ and polyphos‐phoinositides, and it may have a pivotal role in restructuring the actin cytoskeleton in response to agonist stimulation. Structure‐function analysis of gelsolin has (1) indicated that its NH2‐terminal half is primarily responsible for modulating actin filament length and polymerization; and (2) elucidated mechanisms by which Ca2+ and phospholipids may regulate such functions. Gelsolin is functionally and structurally similar (...) to villin, another Ca2+‐activated actin‐severing protein found in microvilli, suggesting that gelsolin may be a prototype of this family of actin‐modulating proteins. A molecular variant of gelsolin is secreted and may be involved in the clearance of actin filaments released during tissue damage. The two forms of gelsolin are encoded by a single gene, and distinct messages are derived by alternative message splicing. (shrink)

Commentators are divided on the interpretation of Metaphysics Z4 1029b13–22. For one thing, it is unclear whether the passage rejects a claim about the essence of surface, or about the essence of pale. It is usually thought that the claim is disavowed because it involves a circular definition. However, this is conjectural, since Aristotle does not explicitly say anything about circularity in the lines in question. I argue here for an alternative account, which reads the disputed lines as an extension (...) of the immediately preceding remarks. If correct, this also solves the problem as to just what Aristotle is denying. As will emerge, my story is helped by St. Thomas’ reading of lines 21–22, an account that has been curiously ignored in the recent literature. (shrink)

This paper defends a 'punctivist' conception of consciousness from recent attacks by Ian Phillips and Matthew Soteriou. As we intend it, 'punctivism' is the view that a subject's experience over some interval is determined by their experiential states at each instant during it. Phillips and Soteriou both offer ingenious arguments purporting to show that the punctivist is unable to make sense of motion perception; and that only by adopting an 'holistic' conception -- whereby a subject's instantaneous experiences are determined by (...) their experience over the interval -- can we make sense of the puzzles such phenomena pose. We contend that both arguments invoke dubious claims, their proffered solutions come with highly controversial commitments, and, if we take punctivism seriously, it is difficult to see why the so-called puzzles should be puzzling in the first place. A punctivist model of motion perception is proposed in response, and objections anticipated. (shrink)

The moral case for experimentation on animals rests both on the goods to be realized, the evils to be avoided thereby, and on the duty to respect persons and to secure them in the enjoyment of their natural moral rights. Some experimentation on animals presents no problems of justification as it involves no harm at all to the animals which are the subject of experiments and is such as to seek to achieve an advance in knowledge. Experiments on non-sentient animals, (...) like those on plant life, may harm the subjects but in ways that in themselves need raise no morally significant issues. Moral issues may arise if the subjects of experiments are members of an endangered species and for like reasons but not simply on account of the harm caused by the experiment to the subjects. Other experimentation on animals is to be justified solely in terms of its benefit to animals, even though it involves harm to the animals upon which experiments are performed. There are many poisons and diseases to which animals and not human beings are exposed which give rise to the need for experiments to determine effective therapies, treatments, or other remedies. Examples include annual rye grass toxicity, foot-and-mouth disease, the many fowl diseases, and so on. Human beings commonly have an interest in successfully experimenting to find effective remedies, either a financial interest as with farm animals, race horses and the like, amusement interest as with pets, or a concern not to have a species or variety become extinct. The moral case for such experiments may be strengthened by reference to such interests if they in turn have a moral basis, but generally it does not depend for its validity on this. Other experimentation that harms the animals involved is to be justified in terms of the benefits to be realized and evils lessened for persons by the knowledge and the use of the knowledge gained, where the knowledge is used to secure the enjoyment of their moral rights by persons. Much experimentation benefits both persons, contributing to the securing of their enjoyment of their moral rights, and animals which do not possess moral rights, and is to be morally justified on both counts. Obviously a great amount of experimentation occurs today which does not admit of justification along any of these lines, and hence, is such that it must be condemned as being morally wrong. (shrink)

If James has a latent tuberculosis infection , he is at risk of developing active tuberculosis disease but he is not yet sick. LTBI is a liminal space between health and illness. Diagnosed with LTBI, James could be conceptualised as having a liminal body. Treatments for LTBI are available, but why would a person seek treatment for a disease he does not yet have? One thing is definite: James needs to be educated about the symptoms and severity of active tuberculosis (...) disease. (shrink)

OBJECTIVES: To determine the relationship between ethical reasoning and gender and occupation among a group of male and female nurses and doctors. DESIGN: Partialist and impartialist forms of ethical reasoning were defined and singled out as being central to the difference between what is known as the "care" moral orientation (Gilligan) and the "justice" orientation (Kohlberg). A structured questionnaire based on four hypothetical moral dilemmas involving combinations of (health care) professional, non-professional, life-threatening and non-life-threatening situations, was piloted and then mailed (...) to a randomly selected sample of doctors and nurses. SETTING: 400 doctors from Victoria, and 200 doctors and 400 nurses from New South Wales. RESULTS: 178 doctors and 122 nurses returned completed questionnaires. 115 doctors were male, 61 female; 50 nurses were male and 72 were female. It was hypothesised that there would be an association between feminine subjects and partialist reasoning and masculine subjects and impartialist reasoning. It was also hypothesised that nurses would adopt a partialist approach to reasoning and doctors an impartialist approach. No relationship between any of these variables was observed. (shrink)

Despite evidence from cognitive psychology that men and women are equal in measured intelligence, gender differences in self-estimated intelligence are widely reported with males providing systematically higher estimates than females. This has been termed the male hubris, female humility effect. The present study explored personality factors that might explain this. Participants provided self-estimates of their general IQ and for Gardner’s multiple intelligences, before completing the Cattell Culture Fair IQ test as an objective measure of intelligence. They also completed the Bem (...) Sex Role Inventory as a measure of sex-role identification, and measures of general and academic self-esteem. Both gender and sex-role differences were observed for SEI, with males and participants of both genders who scored high in masculinity offering higher self-estimates. By comparing estimated and observed IQ, we were able to rule out gender differences in overall accuracy but observed a pattern of systematic underestimation in females. An hierarchical multiple regression showed significant independent effects of gender, masculinity, and self-esteem. Mixed evidence was observed for gender differences in the estimation of multiple intelligences, though moderately sized sex-role differences were observed. The results offer a far more nuanced explanation for the male hubris, female humility effect that includes the contribution of sex role identification to individual and group differences. (shrink)
