Lasch, Sabrina Schützenhofer;Mota, Helena Bolli;Cielo, Carla Aparecida;
Revista CEFAC , 2010, DOI: 10.1590/S1516-18462009005000047
Abstract: purpose: to investigate monolingual and bilingual girls and boys performance, in the skills of phonological awareness. methods: questionnaire and hearing screening to select the sample, consisting of 89 students, aged 4:1 to 8:11-years old, 47 girls and 42 boys, of which 47 subjects were bilingual (portuguese and german) and 42 monolingual (portuguese). the selected sample was submitted to the assessment of skills in phonological awareness, applying the phonological awareness protocol (cielo, 2001) that suggests segmentation of sentences in words, nominal realism, rhyme detection, syllabic synthesis and segmentation, syllable detection, syllabic and phonemic reversion, phonemic exclusion, phoneme detection and phonemic synthesis and segmentation. for a quantitative data analysis, a statistical test of kruskal-wallis with p = 0.05 was taken when comparing the monolingual boys' and girls' performance, and the bilingual boys' and girls' performance by task of phonological awareness. results: when the bilingual subjects were analyzed, there was a statistical significance in the detection of rhyme with trisyllable (p=0,0087) and synthesis of four phonemes (p=0,0219), with advantage of girls, while in the analysis that compared monolingual boys and girls, the results were more balanced. conclusions: despite of almost lacking statistically significant results in the comparison among bilingual and monolingual boys and girls, female superiority was observed in most of phonological awareness tasks.

Abstract: OBJETIVO: investigar o desempenho de meninas e meninos, monolíngues e bilíngues, em habilidades de consciência fonológica. MéTODOS: questionário e triagem auditiva para selecionar a amostra, composta por 89 estudantes, faixa etária entre 4:1 a 8:11 anos de idade, 47 meninas e 42 meninos, dos quais 47 sujeitos eram bilíngues (português e alem o) e 42 monolíngues (português). A amostra selecionada foi submetida à avalia o das habilidades em consciência fonológica, com aplica o do Protocolo de Consciência Fonológica (Cielo, 2001) que prop e tarefas de segmenta o de frases em palavras; realismo nominal; detec o de rimas; síntese silábica; segmenta o silábica; detec o de sílabas; revers o silábica; exclus o fonêmica; detec o de fonemas; síntese fonêmica; segmenta o fonêmica e revers o fonêmica. Para uma análise quantitativa dos dados, realizou-se o teste estatístico de Kruskal-Wallis com p=0,05 quando se comparou o desempenho de meninos e meninas monolíngues, bem como o desempenho de meninos e meninas bilíngues por tarefa de CF. RESULTADOS: quando analisados os sujeitos bilíngues, houve significancia estatística na detec o de rima com trissílabos (p=0,0087) e na síntese de quatro fonemas (p=0,0219), com vantagem das meninas; já na análise que comparou meninos e meninas monolíngues, os resultados foram mais equilibrados. CONCLUS ES: apesar de praticamente n o existirem resultados estatisticamente significantes na compara o entre meninos e meninas bilíngues e monolíngues, observou-se superioridade feminina na maioria das tarefas de consciência fonológica.

Abstract: OBJETIVO: descrever os tempos máximos de fona o (TMF) e características vocais acústicas de mulheres adultas jovens com nódulos vocais. MéTODOS: coleta dos TMF das vogais /a/, /i/ e /u/; da rela o s/z e medidas acústicas da fonte glótica (Multi Dimensional Voice Program Advanced da Kay PENTAX) de 20 sujeitos do sexo feminino, com faixa etária entre 20 e 40 anos, dez com laudo otorrinolaringológico de nódulos vocais e dez com laudo de laringe normal. RESULTADOS: quanto aos TMF, o grupo sem nódulos (GSN) apresentou 90% dos resultados normais e 10% diminuídos, e o grupo com nódulos (GCN) apresentou 70% dos resultados normais e 30% diminuídos; na rela o s/z, todo o GSN apresentou resultados dentro dos padr es da normalidade e o GCN apresentou 70% de resultados normais e 30% aumentados; ambos os grupos apresentaram todas as medidas vocais acústicas dentro da normalidade, com exce o do GSN que apresentou vf0 aumentada. CONCLUS O: as mulheres jovens com nódulos vocais apresentaram medidas de TMF e de rela o s/z sem diferen as significativas em rela o às mesmas medidas de mulheres sem afec o laríngea. As medidas acústicas da fonte glótica foram semelhantes e dentro da normalidade para ambos os grupos, com exce o da medida do cociente de varia o de frequência fundamental (vf0) que foi elevada no GSN, sugerindo incoordena o penumofonoarticulatória. As medidas de TMF e da rela o s/z, mesmo sem diferen as significativas, pareceram mais sensíveis à presen a do predomínio aerodinamico dos nódulos vocais do que as medidas acústicas.

Towards an operator-algebraic construction of integrable global gauge theories
Gandalf Lechner,Christian Schützenhofer
Physics , 2012,
Abstract: The recent construction of integrable quantum field theories on two-dimensional Minkowski space by operator-algebraic methods is extended to models with a richer particle spectrum, including finitely many massive particle species transforming under a global gauge group. Starting from a two-particle S-matrix satisfying the usual requirements (unitarity, Yang-Baxter equation, Poincar\'e and gauge invariance, crossing symmetry, ...), a pair of relatively wedge-local quantum fields is constructed which determines the field net of the model. Although the verification of the modular nuclearity condition as a criterion for the existence of local fields is not carried out in this paper, arguments are presented that suggest it holds in typical examples such as nonlinear O(N) sigma-models. It is also shown that for all models complying with this condition, the presented construction solves the inverse scattering problem by recovering the S-matrix from the model via Haag-Ruelle scattering theory, and a proof of asymptotic completeness is given.
Das interaktive Chirurgische Logbuch im Praktischen Jahr: Eine mehrj hrige Retrospektive [Interactive Logbook in the Surgical Training of Final Year Medical Students: A Four-Year Retrospective]
Kadmon, Martina,Roth, Susann,Porsche, Monika,Schürer, Sabrina
GMS Zeitschrift für Medizinische Ausbildung , 2009, DOI: 10.3205/zma000614
Abstract: [english] Aims: An interactive surgical logbook was introduced in 2004 as part of a reform of the 16-week surgical training period of the final medical year at Heidelberg University. The present work describes its aims and development and examines its utilization by students and supervising doctors over a period of four years. Methods: The surgical training period of the final medical year was evaluated in 2003 by means of questionnaires and interviews with doctors, nurses, orderlies, and final-year medical students. Subsequently, a catalog of training objectives was compiled, which formed the basis for a logbook that states the training objectives, outlines the curriculum of the surgical training period, and includes separate pages for documenting 31 different medical procedures including the treatment of three patients under one’s care. It further includes tables for recording one’s attendance at training activities and detachable forms for self-assessment, evaluation of the surgical training period, and assessment of the student by the training doctors. The logbook was given to all students in their final-year surgical training period, but its use was optional. The entries in all returned logbooks were retrieved, recorded, and analyzed. Results: The return rate of the logbooks was initially low but rose within two years to 80%–100%. The extent of the entries was, however, continuously poor. Nineteen percent of the logbooks were devoid of entries, approximately 40% had no entries of clinical procedures, and the majority of the rest contained very incomplete records. The extent of feedback and comments by the supervising doctors was very limited, and their assessment forms often were filled in by the students themselves. By contrast, students returned numerous self-assessment and evaluation questionnaires that were complete and contained differentiated entries. Informal interviews with students revealed that cooperation was lacking on the part of the training doctors, and the long hours spent in the operating room placed considerable restrictions on the regular use of the logbook. However, low motivation of students who are not interested in surgery must also be considered. Conclusion: The interactive surgical logbook developed in cooperation with final-year medical students is potentially an effective measure for promoting the acquisition of a targeted learning strategy and individually designing one’s own training program. Its efficiency, however, depends on active support by the training doctors and motivation on the part of the students. To overcome
Human Resources Information System (HRIS): A Theoretical Perspective  [PDF]

Journal of Human Resource and Sustainability Studies (JHRSS) , 2014, DOI: 10.4236/jhrss.2014.22004
Abstract: HRIS is one of the major modern HR tools. In developed countries, it became popular since the be-ginning of this century. In Bangladesh, corporate organizations have started to implement HRIS in last 5 years. But still its implementation is limited within the big corporate houses. Small corporate houses and public organizations have failed to realize the benefits of HRIS and taken hardly any initiative to implement the system. The major barrier to success of HRIS is the lack of management commitment. The major limitation is the high cost. But the benefits of the HRIS are more than the limitations. Once it is implemented in any organization, employees and management have accepted and realized the benefits. But to get it implemented is a challenge. This study is an attempt to provide a theoretical analysis of the HRIS implementation with analysis of benefits, limitations and barriers. A case study was prepared to provide a better understanding of the topic in a real life context.
Evaluation of Durability Conferred by an Oleothermic Treatment on Chestnut and Douglas fir through Laboratory and in Field Tests  [PDF]

Open Journal of Forestry (OJF) , 2013, DOI: 10.4236/ojf.2013.32011
Abstract:

The research evaluated two wood species, chestnut and Douglas fir, that are widespread in Tuscany, treated with an oleothermicprocess. Efficacy of this treatment against fungal decay was assessed through laboratory and field tests. The aim of this research was to investigate if an oleothermic process could add value to these natural resources when utilized in Use Class 4 (EN 335) for agricultural purposes such as vineyard poles. The treatment was effective on sapwood of both wood species in laboratory test, giving a protection similar to the untreated heartwood but in case of chestnut, it was easily washed away. In field test the leaching during the outdoor exposure reduced the resistance to fungal decay in both species.
