Introduction: entire hands and main fingers

The ten-volume edition of The Collected Works of Thomas Heywood, forthcoming from Oxford University Press from 2015 to 2022, will attempt to place Heywood’s plays, poetry, and prose back where they belong: at the centre of the study of early modern English literature, drama, and theatre history. Especially as an actor, playwright, reviser, editor, and historical chronicler, Heywood had the longest and widest-ranging career of his contemporaries and thus can reveal how sixteenth- and seventeenth-century authors and theatrical and literary audiences came to see the practice and production of drama.

A hands-on approach for fitting long-term survival models under the GAMLSS framework

In many data sets from clinical studies there are patients insusceptible to the occurrence of the event of interest. Survival models which ignore this fact are generally inadequate. The main goal of this paper is to describe an application of the generalized additive models for location, scale, and shape (GAMLSS) framework to the fitting of long-term survival models. in this work the number of competing causes of the event of interest follows the negative binomial distribution. In this way, some well known models found in the literature are characterized as particular cases of our proposal. The model is conveniently parameterized in terms of the cured fraction, which is then linked to covariates. We explore the use of the gamlss package in R as a powerful tool for inference in long-term survival models. The procedure is illustrated with a numerical example. (C) 2009 Elsevier Ireland Ltd.

On the preparation of clean tungsten single crystals

The cleaning procedure consists of two-step-flashing: (i) cycles of low power flashes T similar to 1200 K) at an oxygen partial pressure of P(o2) = 6 x 10(-8) mbar, to remove the carbon from the surface, and (ii) a single high power flash (T similar to 2200 K), to remove the oxide layer. The removal of carbon from the surface through the chemical reaction with oxygen during low power flash cycles is monitored by thermal desorption spectroscopy. The exposure to O(2) leads to the oxidation of the W surface. Using a high power flash, the volatile W-oxides and the atomic oxygen are desorbed, leaving a clean crystal surface at the end of procedure. The method may also be used for cleaning other refractory metals like Mo, Re and It. (C) 2009 Elsevier B.V. All rights reserved.

Protecting clean critical points by local disorder correlations

We show that a broad class of quantum critical points can be stable against locally correlated disorder even if they are unstable against uncorrelated disorder. Although this result seemingly contradicts the Harris criterion, it follows naturally from the absence of a random-mass term in the associated order parameter field theory. We illustrate the general concept with explicit calculations for quantum spin-chain models. Instead of the infinite-randomness physics induced by uncorrelated disorder, we find that weak locally correlated disorder is irrelevant. For larger disorder, we find a line of critical points with unusual properties such as an increase of the entanglement entropy with the disorder strength. We also propose experimental realizations in the context of quantum magnetism and cold-atom physics. Copyright (C) EPLA, 2011

The interaction between atoms of Au and Cu with clean Si(111) surface: A study combining synchrotron radiation grazing incidence X-ray fluorescence analysis and theoretical calculations

In order to evaluate the interactions between Au/Cu atoms and clean Si(l 11) surface, we used synchrotron radiation grazing incidence X-ray fluorescence analysis and theoretical calculations. Optimized geometries and energies on different adsorption sites indicate that the binding energies at different adsorption sites are high, suggesting a strong interaction between metal atom and silicon surface. The Au atom showed higher interaction than Cu atom. The theoretical and experimental data showed good agreement. Crown Copyright (C) 2009 Published by Elsevier B.V. All rights reserved.

Comparison of learning between Digital gallery and Hands-on Laboratory

This thesis has been done in ROM (Royal Ontario Museum) located in Toronto Canada. It focuses on learning in two parts of the museum. It tries to find out how much each part is effective in terms of learning. Studies have been done in the Digital gallery, which has been equipped with digital video projector and workstation that allows visitors to interact with the collections in 2 or 3 dimensional spaces while they are watching the presenting film. The rest of the study was in Hands-on laboratory, which allows students to examine artifacts and discuss their findings .The method was used in this research is Concept mapping .In Digital gallery, 24 schools surveys in the form of pre-post- test by help of the concept mapping method has been done. In Hands-on laboratory, 12 schools have been studied by using the combination of interviewing and written pre post-test of concept mapping.

Clean Code vs Dirty Code : Ett fältexperiment för att förklara hur Clean Code påverkar kodförståelse

Stora och komplexa kodbaser med bristfällig kodförståelse är ett problem som blir allt vanligare bland företag idag. Bristfällig kodförståelse resulterar i längre tidsåtgång vid underhåll och modifiering av koden, vilket för ett företag leder till ökade kostnader. Clean Code anses enligt somliga vara lösningen på detta problem. Clean Code är en samling riktlinjer och principer för hur man skriver kod som är enkel att förstå och underhålla. Ett kunskapsglapp identifierades vad gäller empirisk data som undersöker Clean Codes påverkan på kodförståelse. Studiens frågeställning var: Hur påverkas förståelsen vid modifiering av kod som är refaktoriserad enligt Clean Code principerna för namngivning och att skriva funktioner? För att undersöka hur Clean Code påverkar kodförståelsen utfördes ett fältexperiment tillsammans med företaget CGM Lab Scandinavia i Borlänge, där data om tidsåtgång och upplevd förståelse hos testdeltagare samlades in och analyserades. Studiens resultat visar ingen tydlig förbättring eller försämring av kodförståelsen då endast den upplevda kodförståelsen verkar påverkas. Alla testdeltagare föredrar Clean Code framför Dirty Code även om tidsåtgången inte påverkas. Detta leder fram till slutsatsen att Clean Codes effekter kanske inte är omedelbara då utvecklare inte hunnit anpassa sig till Clean Code, och därför inte kan utnyttja det till fullo. Studien ger en fingervisning om Clean Codes potential att förbättra kodförståelsen.

"Det är så enkelt, bara hands on, sen är de där" : Digitala hjälpmedel och litteracitet på sfi

Denna studie har till syfte att beskriva tre lärares erfarenheter av digitala hjälpmedel inom sfi-undervisningen med fokus riktat på iPad. Studien är kvalitativ och ger svar på frågor kring lärarnas erfarenhet av litteracitetsutveckling, motivation och det individuella arbetet i klassrummet. Metoden omfattas av intervjuer som bygger på tre frågeställningar. Hur upplever lärarna litteracitetsutveckling och motivation hos de studerande vid användning av iPad och ett annat digitalt hjälpmedel? Hur ser lärarna på de enskilda studenternas behov vid användning av iPad och ett annat digitalt hjälpmedel? Vilken utveckling ser lärarna med iPad i framtida perspektiv? . Resultatet har analyserats och diskuterats i relation till tidigare forskning kring litteracitet, digitala hjälpmedel i undervisningen samt en rapport om iPad i skolan. I den första frågeställningen är lärarna överens om att litteracitetsutvecklingen med iPad relateras till vilken nivå de studerande uppnått. Ju lägre skriftspråksutvecklingsnivå ju lämpligare är språkinlärning med iPad som digitalt hjälpmedel. Detta på grund av dess enkla användarvänlighet. Lärarna anser också att enkelheten och den snabba responsen som de studerande får har en motiverande effekt. De som uppnår en högre skriftspråksutvecklingsnivå i svenska och som behöver mer utvecklande skrivövningar använder i föreliggande undersökning dator. I andra frågan diskuteras den individuella aspekten kring användning av iPad. De tre lärarna i studien anser att iPaden är ett bra verktyg och de har positiva erfarenheter om de studerandes individuella arbete och kan på ett enkelt sätt tillgodose individuella önskemål och behov hos de studerande. I den tredje frågan diskuteras iPad i ett framtida perspektiv. De tre lärarna ser iPaden som ett bra verktyg i en vidare utveckling av sfi. De menar att Skolverkets krav tillgodoses på ett lämpligt sätt med detta digitala hjälpmedel.

The hand of God is over their hands (Q. 48:10) : on the notion of covenant in al-Ṭabarī’s account of Karbalāʾ

This article is an analysis of the story of the killing of Ḥusayn b. ʿAlī at Karbalāʾ in 61/680, as it is presented by Abū Jaʿfar Muḥammad b. Jarīr al-Ṭabarī (d. 310/923). The main argument is that the notion of the divine covenant, which permeates the Qur’an, constitutes a framework through which al-Ṭabarī views this event. The Qur’anic idea of the covenant is read in structural/thematic continuity with the Hebrew Bible account of the covenant between Yahweh and the Hebrew people, which has, in turn, been traced back in its basic form to Late Bronze Era treaties between rulers and their vassals.   The present study focusses on four speeches ascribed to Ḥusayn during the encounter he and his group had with the vanguard of the Kūfan army led by al-Ḥurr. These are analysed in accordance with their use of Qur’anic covenant vocabulary. They are also categorised within the broader framework of the eight standard characteristics of Ancient West Asian and Biblical covenants, as presented by George Mendenhall and Gary Herion, which have recently been developed in a Qur’anic context by Rosalind Ward Gwynne. This article argues that al-Ṭabarī’s Karbalāʾ narrative presents the pact of loyalty to Ḥusayn as a clear extension of the divine covenant.

Performance de fundos mútuos de investimento no Brasil : uma análise dos fenomenos de "hot-hands", sinalização e persistência de retornos

o presente trabalho apresenta um resumo não só dos conceitos básicos sobre fundos de investimento, como também seu histórico e evolução no Brasil e no mundo, o contexto institucional nacional e os principais ratings de classificação de performance. Sua parte empírica foca-se no exame do fenômeno de persistência de performance para os fundos de investimentos ativos brasileiros entre julho de 1996 e junho de 2001. o estudo empírico dividiu-se em três partes: a comparação do retomo das categorias de fundos de ações ativos, de renda fixa e multimercados com os respectivos benchmarks e fundos passivos; a verificação do fenômeno de persistência baseando-se em Malkiel (1995); e a análise dos resultados de investimentos em portfólios formados pelos grupos de uma mesma categoria pertecentes a um mesmo percentil de retomo não ajustado ao risco.

Nuclear-follower foraging associations among Characiformes fishes and Potamotrygonidae rays in clean waters environments of Teles Pires and Xingu rivers basins, Midwest Brazil

Por meio de observações sub e supra-aquáticas foram registradas associações alimentares do tipo nuclear-seguidor entre três espécies de peixes characiformes - Chalceus epakros, Hemiodus semitaeniatus e Hemiodus unimaculatus - e uma espécie de raia de água doce - Potamotrygon orbignyi - nas bacias dos rios Teles Pires e Xingu, no Centro-Oeste do Brasil. Os peixes teleósteos foram observados seguindo as raias quando estas revolviam o substrato à procura de invertebrados, formando discretas nuvens de sedimento. Essas situações atraíram os peixes que se aproximaram das raias para se alimentar de pequenas presas e outros tipos de alimentos expostos desta forma. Esse é um típico exemplo de relação comensal onde um participante é beneficiado enquanto o outro não é prejudicado e representa o segundo registro na literatura de associação alimentar do tipo nuclear-seguidor entre raias potamotrigonídeas e peixes teleósteos, demonstrando o potencial de estudos naturalísticos para a descoberta de novas interações envolvendo espécies de peixes de água doce.

Uma intervenção educativa para profissionais de saúde na prevenção de pneumonia associada à ventilação mecânica

Quasi-experimental study, prospective with quantitative approach, performed at the Hospital do Coração in Natal, aimed at verified the existence of difference between the care given by health professionals to the patients under mechanical ventilation (MV) in the Intensive Care Unit, before and after an educative intervention. The population was of 31 professionals, with data collected between november 05 of 2007 to march 27 of 2008. The results show a yong population, female gender, middle level of education, nursing technique, working between 05 and 09 years on nursing profession, and 01 to 04 years on Intensive Care Unit; almost all, never had an kind of training over prevent pneumonia associated to mechanical ventilation; from those that had training, occur on the work place with duration from 12 to 24 hours. About endotracheal intubation, the cuff was tested with a sterilized syringe had a positive change after a educative intervention, increased from 75,0% to 100,0%; the sterile guide was used on 75,0% before and 100,0% after an educative intervention. Regarding endotracheal suction procedure, was not informed to the patient on 72,7% before, however was informed on 56,7% after; the hands was not previously washed 68,5% before, however was 63,3% after the procedure; mask was used on 74,2 % opportunities before and 76,7% after; the aspiration catheter had adequated size on 98,9% observation before and 100,0% after; the gaze was sterilized on 95,7% before and 100,0% after; the ventilator was connected to the patient during the aspiration intervals on 94,4% observation before and 100,0% after; the ambu bag was clean and protected on 76,1% before and 85,7% after; the aspiration catheter was discarded after be used on 98,9% before and 100,0% after; FIO2 was turned to the begging value on 32,9% observation before and 12,0% after; before the procedure 71,9% professions washed their hands and 73,3% after; before, notes of aspiration results were performed on 70,8% observation and 86,7% after. Regarding devices used on respiratory tract, aspirator flasks were not swapped on 84,6% observations before and 71,0% after; daily látex extention change was not performed on 93,6% observation before and 87,1% after; the ambu bag change was not performed on 50,0% observation before even if was duty or unprotected and on 75,8% opportunities was changed, after; nebulization was not prepared with sterile fluids or manipulated aseptically on 65,2% observation before, perhaps was on 71,7% after; before nebulizers were not changed on 65,2% observations, perhaps were on 60,9% after. Concerning ventilator breathing circuits, condense fluids cumulated on circuits were removed on 55,0% opportunities before, and 64,0% after; moisturizer was not filled with sterile water when already had small amount of liquid inside on 78,4% observations before, and 90,2% after; MV circuits were changed on 97,0% observations on presence of visible duty or when presents some kind of failure, before and 98,4% after. About body position, on 51,3% observations the decubitus position change were done before and 78,2% after; fowler position was maitened on 95,5% observations before and 98,2% after; Regarding respiratory physiotherapy, enteral diet was not interrupted before respiratory physiotherapy on 94,9% before and 90,0% after; respiratory physiotherapy devices were not disinfected or sterile on 69,6% observations before but they re on 60,0% after; before the cateter was not tested before introduction enteral diet or medications on 100,0% but after was done on 15,2%. About enteral feeding, intestine motility and measure of stomach contents were not done on 100,0% observations before, but was 15,2% after. We conclude that 05 of 07 valuated procedures in relation to MV, had a significant improvement on quality of care given after educative intervention, when compared before intervention
