Leading the left: sociability and the micropolitics of cultural reproduction in grassroots boxe popolare coaching
No full textThis article explores coaching in boxe popolare (people's boxing) – a style of boxing codified by leftist grassroots groups in contemporary Italy. The paper presents a micro-sociological analysis of data collected during a three-year multi-sited participant observation focusing on Patrick (pseudonym), who is the leading coach of a boxe popolare team. It examines the micropolitics of reproduction via the under-researched notion of ‘sociability’. To contextualise this, a Bourdieusian framework, drawing on the concepts of ‘field’, ‘capital’, ‘habitus’, ‘doxa’ and ‘symbolic violence’, is employed. Findings highlight how boxe popolare is infused with far-left militant culture. Patrick uses sociability strategically, (a) to reproduce an embodied ethics of this specific boxing style; (b) to strengthen the collective values inherent within boxe popolare political milieu; (c) to perform the boxe popolare network; and finally, (d) to legitimise his own authority in the coaching structure. In conclusion, we highlight the importance of sociability for understanding micropolitical influence in coaching practice and consider the emergent idea of hybrid field as a way to better explore the interplay between coaching pedagogy, the political field and beyond
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.

A ±25A Versatile Shunt-Based Current Sensor with 10kHz Bandwidth and ±0.25% Gain Error from -40°C to 85°C Using 2-Current Calibration
No full textAccurate current sensing is critical in many industrial applications, such as battery management and motor control. Precise shunt-based current sensors have been reported with gain errors of less than 1% over the industrial temperature range (-40°C to 85°C) [1]–[4]. However, since they are intended for coulomb counting, their bandwidth is limited to a few tens of Hz, making them unsuitable for battery impedance or motor-current sensing. This paper presents a current sensor with a wide (10kHz) bandwidth and a tunable temperature compensation scheme (TCS), which allows it to be flexibly used with different types of shunts while maintaining high accuracy. A low-cost room-temperature calibration scheme is proposed to optimize gain flatness over temperature by exploiting the shunt's self-heating at large currents. Over the industrial temperature range and a ±25A current range, it achieves state-of-the-art gain error (±0.25%) with both low-cost PCB and stable metal-alloy shunts.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic InstrumentationMicroelectronic
Valutazione della composizione corporea e del profilo alimentare negli atleti di boxe
No full textO boxe é dividido em categorias de acordo com seu peso, visando minimizar as diferenças exercidas pelo peso na força e velocidade. Alterações drásticas na composição corporal são frequentemente praticadas nessa modalidade, e estratégias de restrição alimentar e desidratação severa são praticadas por estes atletas. Sendo assim, o objetivo desse estudo foi realizar uma avaliação do perfil alimentar e da composição corporal em atletas de boxe. Trata-se de um estudo transversal, observacional, no qual foram avaliados 14 atletas homens, com idade média de 24,9 ±6,3 anos. Na antropometria, foram aferidos peso, altura, índice de massa corporal (IMC), circunferências do braço e da cintura, além de dobras cutâneas. Para avaliar o perfil alimentar, foram aplicados três recordatórios 24 horas, e a média dos três dias foi utilizada. O IMC médio foi de 27,4 ± 6,0 kg/m2 e o percentual de gordura médio foi 15,7 ± 8,8%. O consumo calórico médio foi 1960,7 ±528,0 kcal/dia, o consumo proteico foi 1,5 ± 0,5 g/kg/dia, e o consumo de carboidratos foi 2,81 ± 1,5 g/kg/dia. Quanto aos micronutrientes, a maioria dos atletas (>50%) apresentaram um consumo insuficiente de fibras, cálcio, magnésio, potássio, selênio, e das vitaminas A, B9, B2, B6, C, D e E. Este estudo surge como um dos primeiros que avaliaram o perfil alimentar e composição corporal em atletas de boxe, auxiliando na compreensão das necessidades nutricionais dessa modalidade, visando preservar a saúde e potencializar a performance esportiva em todas as fases de treinamento desse esporte.Boxing is divided into categories according to their weight, to minimize the differences exerted by the weight on strength and speed. Drastic changes in body composition are frequently practiced in this modality, and strategies of food restriction and severe dehydration are practiced by these athletes. Therefore, the objective of this study was to carry out an assessment of the food profile and body composition in boxing athletes. This is a cross-sectional study, in which 14 male athletes were evaluated, with a mean age of 24.9 ± 6.3 years. In anthropometry, weight, height, body mass index (BMI), arm and waist circumferences, as well as skinfolds thickness were measured. To assess the food profile, three 24-hour recalls were applied, and the average of the three days was used. The average BMI was 27.4 ±6.0 kg/m2 and the average fat percentage was 15.7 ±8.8%. The average caloric intake was 1960.7 ±528.0 kcal/day, the protein intake was 1.5 ±0.5 g/kg/day, and the carbohydrate consumption was 2.81 ±1.5 g/kg/day. Regarding micronutrients, most athletes (>50%) had an insufficient consumption of fibers, calcium, magnesium, potassium, selenium, and vitamins A, B9, B2, B6, C, D and E. This study appears as one of the first to evaluate the dietary profile and body composition in boxing athletes, helping to understand their nutritional needs, aiming to preserve health and enhance sports performance in all phases of training in this sport.El boxeo se divide en categorías de acuerdo con su peso, visando minimizar las diferencias ejercidas por el peso del pelo en la fuerza y la velocidad.

Archivist, Archaeologist, Author and the Tactile Window
No full textThe idea that the predominant way of engaging with architecture is through vision is not uncommon but also not always the most appropriate given that buildings are also experienced through tactile interventions. This consequence that emphasises visual aesthetics in order to appreciate and understand architecture probably has much to do with the assumed but rather vaguely defined role of the architect as designer in the practice of architectural design. A resulting misapprehension is that architects designing for visual appreciation think that they are actually designing physical space for embodied tactile engagement.
This prioritisation of vision in the way architects think about and approach design is questioned through the design project of the Tactile Window in which the position of the architect is redefined through inhabiting the roles of archivist, archaeologist and author during the design process.
A 16th century portrait of Queen Elizabeth I known as the Ditchley portrait, currently on display at the National Portrait Gallery is used as the source from which the design of the Tactile Window is derived from and refers back to. Questioning the validity of vision as the sole means of engaging with the work, information about the portrait and working methods gathered from the three carefully chosen positions mentioned above are drawn on and applied to the making of this Tactile Window that becomes an alternative Ditchley portrait. Through exploring the hidden historical and current narratives of and in the existing portrait, the presence of the portrait is alluded to on an alternative physical site. Key to this are the working methods of an invented archival system of design reasoning, the unearthing of archaeological texts and assuming of authorship within the individual frameworks of the roles of archivist, archaeologist and author.
The redefined role of the architect as archaeologist takes onboard the unearthing of associated drawings and writings as well as the methods of organising and applying the recovered information to the system set up by the archivist. This analysis of the graphic and text based information is used to formulate historical narratives that are woven into the design project. Whereas traditional archaeology stresses on the study of a site from a site with quantifiable limits to the physical context, the notion of archaeological sites in this instance refers to the places where the stored information is unearthed. Through the careful process of archiving and analysing this information, a new site that is located within both the physical and historical contexts of interest is discovered. The author then draws upon the elements in the archival system that includes the findings of the archaeologist to construct the alternative Ditchley portrait in this new site of the Echoing Cedar, the result of which bears no visual resemblance to the existing work.
The Tactile Window is a reading of the Ditchley portrait in which information about and in the painting is transformed into a design proposal for an inhabited structure. The intended method of interaction with this alternative portrait is not merely restricted to vision but relies on engagement with the other senses. This experience is enhanced by the interplay with certain site conditions such as wind and rain in order to allude to specific aspects of the Ditchley portrait that are not visually apparent in the existing work.
In the processes of excavating, finding and revealing the hidden information to create this alternative portrait, the effects of the visuals afforded by the existing portrait inadvertently begin to fade as the validity of a single means of visual expression is questioned
