Development of carboxymethyl cellulose/ polyphenols gels for textile applications
Authors: Krizova Hana , Wiener Jakub 
Published: July 2013

Abstract

The aim of this study was to determine release rate and changes in polyphenols’ content, which were sorbed to
carboxymethyl cellulose gel and subsequently desorbed. An aqueous extract of blue marc vine variety Fratava was
used as a source of polyphenols. The gel was dried into a solid film and polyphenols were then desorbed again by
dissolving this film in saline (isotonic) solution. Further, the influence of different times of high temperature (180°C)
of drying gel on change in the amount of released polyphenols and also kinetics of their release in re-transfer of
the film on the gel and solution was studied. The process simulates the possible use of carboxymethyl cellulose/
polyphenols film sorbed on textile materials and its contact with the tissues and body fluids such as course of wound
healing.

Object
A retrospective study analyzing medical files of patients who had undergone surgical management for cervical spondylotic myelopathy (CSM) at a single tertiary hospital was performed to determine the time needed by community care physicians to reach a diagnosis of CSM in patients presenting with typical myelopathic signs and symptoms, and to establish the reasons for the delayed diagnosis when present.
Previous studies have documented that early diagnosis and surgical treatment of CSM may improve patients' neurological as well as general outcome. However, patients complaining of symptoms compatible with CSM may undergo lengthy medical investigations and treatments by community-based physicians before a correct diagnosis is made. The authors have found no published data on the process and time frame involved in attaining a diagnosis of CSM in the community setting.

Methods
The medical records of 42 patients were retrospectively reviewed for demographic data, symptoms, time to diagnosis, physician specialty, number of visits involved in the diagnostic process, and neurological status prior to surgery.

Results
The mean time delay from initiation of symptoms to diagnosis of CSM was 2.2 ± 2.3 years. The majority of symptomatic patients (90.4%) initially presented to a family practitioner (69%) or an orthopedic surgeon (21.4%), with fewer patients (9.6%) referring to other disciplines (for example, the emergency department) for initial care. In contrast, the diagnosis of CSM was most often made by neurosurgeons (38.1%) and neurologists (28.6%), and less frequently by orthopedic surgeons (19%) or family physicians (4.8%).

Conclusions
The diagnosis of CSM in the community is frequently delayed, leading to late referral for surgery. A higher index of suspicion for this debilitating entity is required from family practitioners and community-based orthopedic surgeons to prevent neurological sequelae.

Object
Both anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) are used to treat cervical spondylotic myelopathy; however, there is currently no evidence for the superiority of one over the other in terms of patient-rated outcomes. This comparative effectiveness study compared the patient-rated and radiographic outcomes of 2-level ACDF versus 1-level ACCF.

Methods
This single-center study was nested within the EuroSpine Spine Tango data acquisition system. Inclusion criteria were the following: consecutive patients presenting with signs of cervical spondylotic myelopathy who underwent 2-level ACDF or 1-level ACCF between 2004 and 2011. Before and 12 months after surgery, patients completed the multidimensional Core Outcome Measures Index (COMI) and also rated global treatment outcome and satisfaction with care on 5-point Likert scales. Cervical lordosis, segmental height, and fusion rate were assessed radiographically before and immediately after surgery and at the last follow-up (20.4 ± 13.7 months, mean ± SD).

Results
In total, 118 consecutive patients (80 in the ACDF group and 38 in the ACCF group) were included. Age, sex, comorbidity, baseline symptoms, baseline radiographic data, operation duration, and complication rates did not differ significantly between the 2 groups. Blood loss was significantly (p < 0.04) lower in the ACDF group. Postoperative mean segmental height was significantly (p = 0.0006) greater for ACDF (42.0 ± 4.2 mm, mean ± SD) than for ACCF (39.0 ± 4.0 mm), and global average lordosis improved to a significantly (p = 0.003) greater extent in ACDF (by 1.6° ± 4.1°) than in ACCF (by −1.0° ± 4.0°). Fusion rates for ACDF were 97.5% and for ACCF were 94.7% (p = 0.59). The 12-month patient-rated outcomes did not differ significantly between ACDF and ACCF: 82.4% and 68.6% had a good global outcome (operation helped/helped a lot) (p = 0.10), 86.5% and 82.9% were satisfied/very satisfied with care (p = 0.62), and the reduction in the multidimensional COMI was 2.8 ± 2.7 and 2.2 ± 3 points (p = 0.30), respectively. The postoperative increase in lordosis angle showed low but significant correlations with the improvement in arm pain (r = 0.25, p = 0.014), highest pain (r = 0.25, p = 0.013), and function (r = 0.24, p = 0.016).

Conclusions
Both ACDF and ACCF are safe and effective in the treatment of cervical spondylotic myelopathy, indicated by similarly good patient-rated outcomes 1 year after surgery. This precludes any conclusions regarding the superiority of one technique over the other, although it should be noted that ACDF resulted in less blood loss and greater improvements in cervical lordosis and segmental height than ACCF. Patients with improved lordosis angle had a better clinical outcome.
Impacts of After‐School Programs on Student Outcomes
Authors: Zief Susan Goerlich , Lauver Sherri , Maynard Rebecca A. 
Published: July 2013

This Campbell systematic review sought to answer the following questions with the available high quality experimental studies of programs that combined academic programming with other activities such as youth development or recreation:

To what extent and in what ways does access to after‐school programs impact student context (i.e., student location, supervision, and safety), participation in enriching activities, behaviors, social and emotional development, and academic outcomes for youth?
Do the effects of after‐school programs vary among subgroups of youth defined by their baseline characteristics?
Among the program models and settings evaluated, do some seem more beneficial to youth than others? What are the distinguishing characteristics of those more and less successful programs? This review only included well‐implemented experimental design studies.
An extensive search of the literature uncovered only five studies that met the inclusion criteria for this review. The five evaluated programs were fairly homogenous along many dimensions, including their target populations and settings–primarily elementary youth living in lower‐ income, urban settings. Notably, looking across the 97 impacts measured by the five studies included in this review reveals primarily null findings–84 percent showed no significant differences between the program and control youth. Also, not one of these studies reported impacts for parents. In this era of welfare reform, it might be important to understand how this type of intervention targeting low‐income youth may impact parents' job attendance and retention or parental levels of stress while balancing the demands of work and child care. Such parental outcomes could arguably mediate student social and emotional, behavioral, and academic outcomes.
The Effects of School‐Based Social Information Processing Interventions on Aggressive Behavior, Part I: Universal Programs
Authors: Wilson Sandra Jo , Lipsey Mark W. 
Published: July 2013

This Campbell systematic review examines the effects of universal school‐based social information processing interventions on the aggressive and disruptive behavior of school‐age children. Program effects are examined overall and in relation to methodological and substantive differences across studies.The search strategy identified 89 eligible reports, which gave the results of 73 unique research studies of universal school‐based social information processing programs.The research indicates that short, intensive interventions –e.g. 8‐16 weeks of 2‐5 hours a week – are more effective than extended year‐long programmes. Extended programmes may have a tendency to become routine and thus have less impact on the students. Where the education programmes target children in special education classes, the effect is lesser than in ordinary classes. Pupils in special classes may be prone to many other problems which could reduce the impact of this type of education
Transurethral Resection of Bladder Cancer: A Simple and Diffusely-Performed Technique but with Controversial Outcomes
Authors: Brausi Maurizio 
Published: July 2013

Introduction Nowadays TUR is considered the golden standard for the diagnosis and treatment of NMIBC. However, TUR should be adequate: all bladder lesions should be resected and muscle must be present in the specimen in order to correctly stage the tumor. No bladder perforation should be performed and CIS diagnosed. Technique Bimanual palpation pre- and post-TUR should be encouraged, especially in teaching institutions. Urethroscopy should always precede the visualization of the bladder. All the visible tumors should be resected preferably with bipolar resectoscope, to avoid tissue charring and to facilitate the pathological diagnosis. The exophytic part of the tumor should be first resected and the fragment collected in a separate bottle. Tumor base must be biopsied with cold cup. Muscle must be present in the specimen. Fulguration of the tumor base and 1–2 cm around is of paramount importance. Discussion One of the most important parameters for evaluating the quality of TUR is tumor recurrence after 3 months. The EORTC GU Group showed that the 3-month recurrence varied from 0 to 46% between the European institutions participating in randomized prospective EORTC studies. This variability was not explained by the tumor characteristics nor by the adjuvant therapy administered, but by the poor quality of the TUR. The surgeon's performance and poor TUR quality were therefore suggested as being responsible for the results. A second EORTC study confirmed in fact that using a bladder diagram at the moment of diagnosis (signing the areas where the lesions are) and the presence of an experienced surgeon performing TUR were the two significant factors that could reduce the recurrence after 3 months. Conclusions A complete, adequate first TUR is of paramount importance for the outcome of patients with NMIBC. It could be more important than any further adjuvant therapy administered.

DOI: 10.5902/198346595488 This paper aims at analyzing and contrasting the bibliometric forms of five renowned national journals. The theoretical discourses on the use of valuation models, with emphasis on the Krzyzanowski and Ferreira (1998) and the methodology used in the assessment of the Coordination of Improvement of Higher Education Personnel (CAPES, in portuguese) (2007-2009). The period considered was the triennium 2007 to 2009, intentionally coinciding with the evaluation period of Qualis-CAPES. The results suggest that external validation of the classifications of journals made by Qualis CAPES for another "metric" consecrated - Krzyzanowski and Ferreira (1998), and an apparent improvement of the journals studied in the question form for the period surveyed. Another finding on this question it is found that some characteristics of the periodic recurrence, the journals “Revista Contabilidade Finanças” (Faculty of Economics, Business, and Accounting-University of São Paulo), “Revista de Administração Pública” (Getúlio Vargas Foundation) and “Revista de Contabilidade Vista Revista” (Federal University of Minas Gerais), as the apparent inbreeding, the result of a substantial concentration of researchers working at universities south-southeast of Brazil.

DOI: 10.5902/198346597845 This paper aims to determine, in a group of companies from the Brazilian electric sector, if there is a relationship between the return on investment (ROI) and the concept of efficiency estimated by the method Data Envelopment Analysis (DEA), as well as evaluating the growth of productivity based on Malmquist Index (Fare et al, 1996). The hypothesis is that firms that had return on investment higher during certain period of time are those employed their resources efficiently in getting their outputs (DEA efficient). The input (1) Products (5) DEA model correspond to the operating cost (I), the network length (km), the number of consumers and the market billed high, medium and low voltage, respectively. The sample consisted of 31 companies of Brazilian electricity distribution and timing of the study was from 2007 to 2009. We calculated the Malmquist index (M0), represented by the change in total factor productivity (TFPC), which is composed by the evolution of technical efficiency (EC) and the change in the technological frontier (TC) of the companies were also determined ROI for each period. We calculated the correlation between the TFPC, TC, EC, score the DEA and the ROI for the period 2007 to 2009. The results showed a positive correlation, although weak, between efficiency change and the indexes mentioned above, rejecting the initial hypothesis
<b>Repensado a performance na educação - intuições e problemas na recepção</b>
Authors: Conte Elaine 
Published: July 2013

http://dx.doi.org/10.5902/198464443978 O debate sobre a performance surge entre os temas atuais da educação como ação que fazemos através de um processo discursivo, que converge para uma estética corporificada no agir, cujo poder linguístico-expressivo é descentrado no trabalho pedagógico. Nesta abordagem, a performance configura-se como uma expressão refinada de comunicação, um elemento de troca intersubjetiva para se fazer entender nas esferas artísticas, filosóficas e pedagógicas, facilitando as conversações, criando laços, aproximando os sujeitos e embelezando a vida e a arte de educar. O trabalho trata dos efeitos da performance na educação, buscando romper com a racionalidade técnica das verticalidades mercadológicas e impulsionar a dimensão plural do devir linguístico criador de sentidos à realização humana, que é o próprio uso expressivo das palavras nas diferentes atuações. Trata-se de uma retomada da performance pelo caminho da inspiração hermenêutica, que permite sair de certos mecanismos operacionais destituídos de subjetividade para criar possibilidades estético-discursivas, cujas expressões sensíveis e valorativas passam pela alteridade e pelo reconhecimento das diferenças. A pesquisa se vale de contribuições de pensadores que, mesmo não tendo se debruçado profundamente sobre a questão, souberam formular interrogações que dizem respeito ao agir humano, ao desempenho linguístico e a atitude performática. A performance na perspectiva do uso comunicativo agrega todos os produtos da cultura, da arte, da vida cotidiana, da literatura, do cinema, como elementos linguísticos para encontrarmos respostas aos obstáculos do mundo e às necessidades intrínsecas da formação educativa, englobando as racionalidades do mundo objetivo, social e subjetivo.

http://dx.doi.org/10.5902/198464444379 Este artigo aborda a importância da formação inicial e continuada e da prática do professor tomando como referencial os desafios da proposta crítico reflexiva. Tivemos o objetivo de: investigar os pressupostos que embasam a atual formação e prática do professor; pesquisar e analisar as principais dificuldades encontradas para o desenvolvimento da prática docente; compreender e analisar a complexidade inerente a atuação docente dos anos iniciais do ensino fundamental. Para isto realizamos um levantamento bibliográfico considerando as características da formação do profissional critico reflexivo. Realizamos também uma pesquisa qualitativa junto a docentes das séries iniciais do ensino fundamental. Os resultados indicaram que apesar de os docentes conceberem o processo de ensino e aprendizagem como contínuo, eles não investem nesta possibilidade de formação. Constatamos também que a pratica docente se revela mesclada por atitudes e ações reprodutivistas e por atitudes e ações críticas e reflexivas. Assim se desejarmos investir em uma formação e consequentemente em uma prática crítica e reflexiva se torna fundamental repensar tanto a formação inicial como a formação continuada visando o desenvolvimento de habilidades e competências que sensibilizem tanto os docentes como os futuros docentes para a realização de ações críticas e reflexivas.
<b>A formação de Professores Reflexivos: a docência como objeto de investigação</b>
Authors: Fávero Altair Alberto , Tonieto Carina , Roman Marisa Fátima 
Published: July 2013

http://dx.doi.org/10.5902/198464445483 A formação continuada de professores tornou-se assunto obrigatório em nosso tempo. Há um consenso entre os professores e dirigentes escolares que é necessário “educar os educadores”, pois os saberes racionais que foram aprendidos nos processos formativos não são suficientes para enfrentar a complexidade e a diversidade dos problemas que o trabalho docente exige. É necessário e urgente, em qualquer área de atuação, refletir sobre novas formas de exercer os saberes necessários para a prática profissional. No que se refere ao trabalho docente, a reflexão na e sobre a prática possibilita que o educador reveja sua própria atuação. Trabalhos recentes de pensadores e educadores tais como Donald Schön, Isabel Alarcão, António Nóvoa, J. Gimeno Sacristán, Angel Pérez Gómez, dentre outros, projetaram o conceito de profissional reflexivo e com isso a reabilitação da razão prática, o resgate da experiência no processo de aprendizagem, o destaque da intuição nos processos de conhecimento e a centralidade que a reflexão na ação e sobre a ação possui nos processos educacionais. Todo este movimento em torno do conceito de professor reflexivo dá espaço a um conjunto de questionamentos: o que significa ser um professor reflexivo? Em que situações devemos reflexivos? Sobre o que devemos ser reflexivos? Como ser reflexivo? De que maneira podemos tornar a docência objeto de reflexão? O presente texto tem como principal foco analisar a formação continuada de professores a partir do paradigma do professor reflexivo, abordando algumas dessas questões. O texto, além das considerações iniciais, está dividido em duas partes: primeiramente aborda a formação docente a partir da racionalidade técnico-intrumental que prevaleceu nos processo de formação de professores nas três últimas décadas do século XX, mostrando as insuficiências deste processo formativo; na segunda parte sistematiza os principais pressupostos que caracterizam um processo formativo baseado no paradigma do professor reflexivo.

http://dx.doi.org/10.5902/198464445529 O artigo traz alguns resultados de uma pesquisa de Doutorado em que buscou-se investigar os modos de relação das crianças com as narrativas e justifica-se pela importância de entendimento do contexto da criança na atualidade, contexto cada vez mais fluido e mutável. O estudo foi fundamentado nos Estudos Culturais Latino-Americanos que entendem o “cultural” na perspectiva da hibridação (Canclini, 2003) surgindo nas falas das próprias crianças pesquisadas. A investigação ocorreu em diversos campos: três escolas (duas escolas públicas e uma escola particular), um espaço cultural e um Blog. O estudo foi desenvolvido por intermédio de uma pesquisa qualitativa de cunho etnográfico através de oficinas e entrevistas realizadas com as crianças participantes das oficinas e posteriormente com as crianças produtoras de um blog. Os achados da pesquisa apontam a freqüente relação das crianças com a imagem, mostrando o quanto é híbrida a leitura realizada pelas crianças.
