We can work it out: an enactive look at cooperation

The past years have seen an increasing debate on cooperation and its unique human character. Philosophers and psychologists have proposed that cooperative activities are characterized by shared goals to which participants are committed through the ability to understand each other’s intentions. Despite its popularity, some serious issues arise with this approach to cooperation. First, one may challenge the assumption that high-level mental processes are necessary for engaging in acting cooperatively. If they are, then how do agents that do not possess such ability (preverbal children, or children with autism who are often claimed to be mind-blind) engage in cooperative exchanges, as the evidence suggests? Secondly, to define cooperation as the result of two de-contextualized minds reading each other’s intentions may fail to fully acknowledge the complexity of situated, interactional dynamics and the interplay of variables such as the participants’ relational and personal history and experience. In this paper we challenge such accounts of cooperation, calling for an embodied approach that sees cooperation not only as an individual attitude toward the other, but also as a property of interaction processes. Taking an enactive perspective, we argue that cooperation is an intrinsic part of any interaction, and that there can be cooperative interaction before complex communicative abilities are achieved. The issue then is not whether one is able or not to read the other’s intentions, but what it takes to participate in joint action. From this basic account, it should be possible to build up more complex forms of cooperation as needed. Addressing the study of cooperation in these terms may enhance our understanding of human social development, and foster our knowledge of different ways of engaging with others, as in the case of autism.

A new look at the pulsating DB white dwarf GD 358: Line-of-sight velocity measurements and constraints on model atmospheres

We report on our findings of the bright, pulsating, helium atmosphere white dwarf GD 358, based on time-resolved optical spectrophotometry. We identify 5 real pulsation modes and at least 6 combination modes at frequencies consistent with those found in previous observations. The measured Doppler shifts from our spectra show variations with amplitudes of up to 5.5 km s-1 at the frequencies inferred from the flux variations. We conclude that these are variations in the line-of-sight velocities associated with the pulsational motion. We use the observed flux and velocity amplitudes and phases to test theoretical predictions within the convective driving framework, and compare these with similar observations of the hydrogen atmosphere white dwarf pulsators (DAVs). The wavelength dependence of the fractional pulsation amplitudes (chromatic amplitudes) allows us to conclude that all five real modes share the same spherical degree, most likely, l=1. This is consistent with previous identifications based solely on photometry. We find that a high signal-to-noise mean spectrum on its own is not enough to determine the atmospheric parameters and that there are small but significant discrepancies between the observations and model atmospheres. The source of these remains to be identified. While we infer Teff =24 kK and log g ~ 8.0 from the mean spectrum, the chromatic amplitudes, which are a measure of the derivative of the flux with respect to the temperature, unambiguously favour a higher effective temperature, 27 kK, which is more in line with independent determinations from ultra-violet spectra.

A table-top laser-based source of short, collimated, ultra-relativistic positron beams

An ultra-relativistic electron beam passing through a thick, high-Z solid target triggers an electromagnetic cascade, whereby a large number of high energy photons and electron-positron pairs are produced. By exploiting this physical process, we present here the first experimental evidence of the generation of ultra-short, highly collimated and ultra-relativistic positron beams following the interaction of a laser-wake field accelerated electron beam with high-Z solid targets. Clear evidence has also been obtained of the generation of GeV electron-positron jets with variable composition depending on the solid target material and thickness. The percentage of positrons in the overall leptonic beam has been observed to vary from a few per cent up to almost fifty per cent, implying a quasi-neutral electron-positron beam. We anticipate that these beams will be of direct relevance to the laboratory study of astrophysical leptonic jets and their interaction with the interstellar medium.

Look and Tell: Using Photo-Elicitation Methods with Teenagers

This article reflects on the usefulness of photo elicitation in research with young people. As part of an Economic and Social Research Council-funded project exploring conflict and divisions in contested cities, teenagers living or attending schools in segregated areas of Belfast were presented with 11 photographs depicting the city's traditional ethno religious divisions, the new ‘post conflict’ consumerist city and youth subcultures. In response to each photo, the young people produced individual written comments and their opinions were fleshed out during follow-up focus group interviews. Drawing on these responses, the strengths and weaknesses of using photo elicitation in research with young people and its capacity to generate new insights into teenagers' spatial perceptions and experiences are outlined.

Towards core outcome set (COS) development: a follow-up descriptive survey of outcomes in Cochrane reviews

BACKGROUND: A core outcome set (COS) can address problems of outcome heterogeneity and outcome reporting bias in trials and systematic reviews, including Cochrane reviews, helping to reduce waste. One of the aims of the international Core Outcome Measures in Effectiveness Trials (COMET) Initiative is to link the development and use of COS with the outcomes specified and reported in Cochrane reviews, including the outcomes listed in the summary of findings (SoF) tables. As part of this work, an earlier exploratory survey of the outcomes of newly published 2007 and 2011 Cochrane reviews was performed. This survey examined the use of COS, the variety of specified outcomes, and outcome reporting in Cochrane reviews by Cochrane Review Group (CRG). To examine changes over time and to explore outcomes that were repeatedly specified over time in Cochrane reviews by CRG, we conducted a follow-up survey of outcomes in 2013 Cochrane reviews.

METHODS: A descriptive survey of outcomes in Cochrane reviews that were first published in 2013. Outcomes specified in the methods sections and reported in the results section of the Cochrane reviews were examined by CRG. We also explored the uptake of SoF tables, the number of outcomes included in these, and the quality of the evidence for the outcomes.

RESULTS: Across the 50 CRGs, 375 Cochrane reviews that included at least one study specified a total of 3142 outcomes. Of these outcomes, 32 % (1008) were not reported in the results section of these reviews. For 23 % (233) of these non-reported outcomes, we did not find any reason in the text of the review for this non-report. Fifty-seven percent (216/375) of reviews included a SoF table.

CONCLUSIONS: The proportion of specified outcomes that were reported in Cochrane reviews had increased in 2013 (68 %) compared to 2007 (61 %) and 2011 (65 %). Importantly, 2013 Cochrane reviews that did not report specified outcomes were twice as likely to provide an explanation for why the outcome was not reported. There has been an increased uptake of SoF tables in Cochrane reviews. Outcomes that were repeatedly specified in Cochrane reviews by CRG in 2007, 2011, and 2013 may assist COS development.

Seismic retrofitting of RC buildings using CFRP and post-tensioned metal straps: shake table tests

This article examines the effectiveness of two innovative retrofitting solutions at enhancing the seismic behaviour of a substandard reinforced concrete building tested on a shake table as part of the Pan-European funded project BANDIT. To simulate typical substandard construction, the reinforcement of columns and beam-column joints of the full-scale structure had inadequate detailing. An initial series of shake table tests were carried out to assess the seismic behaviour of the bare building and the effectiveness of a first retrofitting intervention using Post-Tensioned Metal Straps. After these tests, columns and joints were repaired and subsequently retrofitted using a retrofitting solution consisting of Carbon Fibre Reinforced Polymers and Post-Tensioned Metal Straps applied on opposite frames of the building. The building was then subjected to unidirectional and three-dimensional incremental seismic excitations to assess the effectiveness of the two retrofitting solutions at improving the global and local building performance. The article provides details of the above shake table testing programme and retrofitting solutions, and discusses the test results in terms of the observed damage, global damage indexes, performance levels and local strains. It is shown that whilst the original bare building was significantly damaged at a peak ground acceleration (PGA) of 0.15g, the retrofitted building resisted severe threedimensional shake table tests up to PGA=0.60g without failure. Moreover, the retrofitting intervention enhanced the interstorey drift ratio capacity of the 1st and 2nd floors by 160% and 110%, respectively. Therefore, the proposed dual retrofitting system is proven to be very effective for improving the seismic performance of substandard buildings.

Invisible cities: the table of contents and the labyrinths of reality

In Invisible Cities (1972), Italo Calvino contrasts a rigid outline structure with a flexible textual content. The tension comprised by the numerical structure proposed in the table of contents stands out against the set of polissemic texts which make up the subject matter of the book. The opposition between form and content point to a fruitful dichotomy in the conception of the novel linked to the theories of the open and closed work. This essay will investigate the structural construction of Invisible Cities by looking at its table of contents, seeking to discuss some models of formalistic representation proposed by the criticism and the specific contribution they may, or may not, provide. The objective is to analyse the pertinence of such theories in the light of historical and cultural approaches. Aiming to uncover possible meanings which arise from the debate, this essay will question to what extent structural complexities can be considered literary if they are not ultimately related to the culture in which a text is found.

Crowland Municipality : an act for regulating and governing auctioneers, and other persons putting up for sale, goods, wares, and merchandise to the highest or best bidder., 1854

On February 1st, 1854 an act was passed in order to regulate the sale of goods, wares and merchandise. Section I pertained to the fact that any merchant would first obtain a license. Section II deemed that no merchant should sell any wine or spirituous liquors, beer or ale within the municipality of Crowland in any less quantity than 5 gallons or less than 12 bottles in any place other than a House of Public Entertainment without having obtained a license. Section III was in regard to licensing any person who would use a billiard table which was set up for hire or gain. Section IV stated that all sums of money paid by the keepers of Houses of Public Entertainment plus the imperial duty of 2 pound would be payable to the Treasurer of the Municipality of Crowland. Section V was written regarding the continuance of the act to regulate inns, taverns, temperance houses and other Houses of Public Entertainment. Section VI specified that all recesses (not authorized to sell liquor) would pay the sum of 2 pounds. Section VII declared that Peter Benedict was appointed Revenue Inspector of the township and section VIII stated that recess-keepers who took out liquor licenses would be required to pay 6 pounds 5 shillings and for violating this they would pay a penalty. This document was written by Leonard M. Matthews, Township reeve and Alex Reid, clerk.

Literary meals in Canada : the Food/books of Austin Clarke, Hiromi Goto, Tessa McWatt and Fred Wah

Literary Meals in Canada étudie Pig Tails ’n Breadfruit d'Austin Clarke, Chorus of Mushrooms et The Kappa Child de Hiromi Goto, This Body de Tessa McWatt, ainsi que Diamond Grill de Fred Wah. Cette thèse entreprend d’établir la signification de la nourriture dans ces récits, ce qu'elle permet aux auteur(e)s d'exprimer par rapport à divers thématiques—les structures sociales, la culture, le langage, ou encore la subjectivité—et comment ils/elles établissent des connexions entre elles, et quelles conclusions ils/elles en tirent. En d'autres termes, cette thèse s'interroge sur les stratégies utilisées par ces auteur(e)s lorsqu'ils écrivent de la “nourritéra-ture.” Ma lecture de ces oeuvres est aussi ancrée au sein d'une conversation sur la nourriture au sens large: que ce soit dans les cercles académiques, dans les supermarchés, par l'intermédiaire des étiquettes, ou dans les médias. J'examine comment mon corpus littéraire répond, infirme, ou confirme les discours actuels sur la nourriture. Divisé en quatre chapitres—Production, Approvisionnement, Préparation, et Consommation—ce mémoire précise la signification du “literary supermarket” de Rachel Bowlby, en s'appuyant sur les travaux de Michael Pollan et Hiromi Goto; compare la haute cuisine d'Escoffier à la “hot-cuisine” d'Austin Clarke; recherche les connections entre l’acte de faire la cuisine et celui de l’écrire chez Luce Giard, Austin Clarke, et Fred Wah; confronte les préceptes d'Emily Post concernant les bonnes manières de la table à la cacophonie et aux bruits de mastication chez Hiromi Goto; et relie Tessa McWatt et Elspeth Probyn qui partagent, toutes deux, un intérêt et une approche à la sustentation des corps. Les textes qui composent ce corpus sont des “foodbooks” (“aliment-textes”). La nourriture, et les différentes activités qui y sont associées, y est transcrite. C’est pourquoi cette thèse accorde une grande importance aux particularités de ce moyen d'expression.

Fourier-Matrizen und Ringe mit Basis

Bei der Bestimmung der irreduziblen Charaktere einer Gruppe vom Lie-Typ entwickelte Lusztig eine Theorie, in der eine sogenannte Fourier-Transformation auftaucht. Dies ist eine Matrix, die nur von der Weylgruppe der Gruppe vom Lie-Typ abhängt. Anhand der Eigenschaften, die eine solche Fourier- Matrix erfüllen muß, haben Geck und Malle ein Axiomensystem aufgestellt. Dieses ermöglichte es Broue, Malle und Michel füur die Spetses, über die noch vieles unbekannt ist, Fourier-Matrizen zu bestimmen. Das Ziel dieser Arbeit ist eine Untersuchung und neue Interpretation dieser Fourier-Matrizen, die hoffentlich weitere Informationen zu den Spetses liefert. Die Werkzeuge, die dabei entstehen, sind sehr vielseitig verwendbar, denn diese Matrizen entsprechen gewissen Z-Algebren, die im Wesentlichen die Eigenschaften von Tafelalgebren besitzen. Diese spielen in der Darstellungstheorie eine wichtige Rolle, weil z.B. Darstellungsringe Tafelalgebren sind. In der Theorie der Kac-Moody-Algebren gibt es die sogenannte Kac-Peterson-Matrix, die auch die Eigenschaften unserer Fourier-Matrizen besitzt. Ein wichtiges Resultat dieser Arbeit ist, daß die Fourier-Matrizen, die G. Malle zu den imprimitiven komplexen Spiegelungsgruppen definiert, die Eigenschaft besitzen, daß die Strukturkonstanten der zugehörigen Algebren ganze Zahlen sind. Dazu müssen äußere Produkte von Gruppenringen von zyklischen Gruppen untersucht werden. Außerdem gibt es einen Zusammenhang zu den Kac-Peterson-Matrizen: Wir beweisen, daß wir durch Bildung äußerer Produkte von den Matrizen vom Typ A(1)1 zu denen vom Typ C(1) l gelangen. Lusztig erkannte, daß manche seiner Fourier-Matrizen zum Darstellungsring des Quantendoppels einer endlichen Gruppe gehören. Deswegen ist es naheliegend zu versuchen, die noch ungeklärten Matrizen als solche zu identifizieren. Coste, Gannon und Ruelle untersuchen diesen Darstellungsring. Sie stellen eine Reihe von wichtigen Fragen. Eine dieser Fragen beantworten wir, nämlich inwieweit rekonstruiert werden kann, zu welcher endlichen Gruppe gegebene Matrizen gehören. Den Darstellungsring des getwisteten Quantendoppels berechnen wir für viele Beispiele am Computer. Dazu müssen unter anderem Elemente aus der dritten Kohomologie-Gruppe H3(G,C×) explizit berechnet werden, was bisher anscheinend in noch keinem Computeralgebra-System implementiert wurde. Leider ergibt sich hierbei kein Zusammenhang zu den von Spetses herrührenden Matrizen. Die Werkzeuge, die in der Arbeit entwickelt werden, ermöglichen eine strukturelle Zerlegung der Z-Ringe mit Basis in bekannte Anteile. So können wir für die meisten Matrizen der Spetses Konstruktionen angeben: Die zugehörigen Z-Algebren sind Faktorringe von Tensorprodukten von affinen Ringe Charakterringen und von Darstellungsringen von Quantendoppeln.

How do I get the Chapter number in Table or Figure captions to restart in Appendices using the University thesis template in Word 2010?

If you have added the Chapter number to your Table or Figure captions they will show as 1.1, 1.2 and so on. This is linked to the numbering used in the Heading 1 style. However, once you get to the Appendices the last Chapter number will continue throughout the Appendices as the Appendix heading isn't Heading 1. So what you need to do is get Word to understand that the style from which it should be picking up the first part of the Caption has changed and that it will need to restart the numbering again in each subsequent Appendix. This isn't too complex but you must follow the instructions to the letter or else it won't work.
