La inclusió a l'aula a través de l'aprenentatge cooperatiu i "l'emoció de conèixer" : anàlisi de la incidència de les estructures cooperatives d'aprenentatge i del projecte amb "l'emoció de conèixer” a partir de dos anàlisi de casos

Curs 2012-2013Aquest document vol exemplificar com mitjançant l’aplicació d’estratègies metodològiques inclusives concretes es pot millorar la situació d’inclusió de dos infants en les seves aules ordinàries. Per tal de dur a terme aquest objectiu el que es fa és oferir una proposta d’innovació didàctica a partir d’estructures cooperatives d’aprenentatge i de l’estratègia metodològica “L’emoció de conèixer” perquè aquests infants augmentin en presència, participació i progrés per acabar sent inclosos significativament dins dels seus grups-classe. Paral·lelament s’analitza la incidència sobre els dos infants de les propostes que s’han dut a la pràctica per valorar-ne el grau d’efectivitat en relació a la millora de la inclusió.This document wants to exemplify how to improve the inclusion of two children in their ordinary classes through the use of specific inclusive methodological strategies. To reach this goal, a proposal will be offered, based on cooperative learning structures and the methodological strategy "the emotion of knowing". With these programs, the children is expected to increase in presence, participation and progress, to end up being significantly included in their class. At the same time, an analysis of the incidence of these proposals to the children will be done, in order to evaluate the degree of efficience regarding the improvement of their inclusion

Emerging approaches

In recent years, the benefits of warm-up in sports performance have received a special interest. New methods have been included in warm-up procedure, but few are known about the effects on running performance and biomechanical responses. Thus, the purpose of the current thesis was to analyze the effect of recent trends of warm-up tasks on sprint performance. Specifically, to verify the effects of including ballistic exercises in warm-up procedures and to analyze the impact of changing biomechanical running patterns during warm-up, conducting a performance, biomechanical, physiological and psychophysiological evaluation of sprints. For this, the following steps were performed: (i) qualitative review on warm-up and performance, focusing on the emerging methods; (ii) to verify the acute effects of a warm-up including ballistic exercises inducing a post-activation potentiation, easy to apply on a real competition context, in repeated 100m running performance; (iii) to understand the acute physiological, psychophysiological and biomechanical responses of including ballistic exercises in repeated 30m running performance; (iv) to analyze the effect of manipulating running kinematics (stride length (SL) and stride frequency (SF)) during warm-up in repeated 30m running performance. The main conclusions of the study were: (i) considering the new trends that have emerged, it can be suggested positive effects on performance after short duration stretches followed by specific muscle activation exercises, and after dynamic stretching, both depending on the duration and intensity; short-duration maximal efforts and specific to the following activity, followed by few minutes of recovery, provide beneficial neuromuscular responses and improved performance in high-intensity and short-term efforts; passive heating during the transition phase between warm-up and main exercise lead to optimization of subsequent performance; (ii) there were benefitial effects of warm-up in 30m and 100m sprinting; (iii) the 100m race is equally optimized after warm-up with or without post-activation potentiation, but with different running kinematics (iv) the positive effects of warm-up on 30m running was caused by faster initial 15m and increased SL in the last 15m of the trial; v) no additional effects on 30m were found after including ballistic exercises during warm-up; (vi) a warm-up focusing in higher SL or higher SF did not result in different 30m sprint performances and running kinematics, despite different running strategies occurred (faster initial meters after warm-ups stimulating SF and faster final meters after warm-up stimulating SL); (vii) the results highlighted the individual response to each warm-up procedure. The main findings of this work emphasize the importance of the warm-up design for short running distances and the need of individualization for optimized performances. Further studies are needed to deeply understand their effects on performance.Nos últimos anos, os benefícios do aquecimento no desempenho desportivo receberam um interesse especial. Novos métodos foram incluídos no processo de aquecimento, mas pouco se conhece sobre os seus efeitos no desempenho de corrida e respostas biomecânicas. Assim, o objetivo a presente tese foi analisar o efeito das tendências recentes de tarefas de aquecimento no desempenho do sprint. Especificamente, verificar os efeitos da inclusão de exercícios balísticos nos procedimentos de aquecimento e analisar o impacto da mudança dos padrões biomecânicos de corrida durante o aquecimento, conduzindo a uma avaliação de performance, biomecânica, fisiológica e psicofisiológica dos sprints. Para isso, foram realizadas as seguintes etapas: (i) revisão qualitativa do aquecimento e desempenho, com foco nos métodos emergentes; (ii) verificar os efeitos agudos de um aquecimento, incluindo exercícios balísticos que induzem uma potenciação pós-ativação, fácil de aplicar em contexto real de competição, no desempenho de corrida repetida de 100m; (iii) compreender as respostas fisiológicas agudas, psicofisiológicas e biomecânicas com a inclusão de exercícios balísticos no desempenho de 30m de sprint repetido; (iv) analisar o efeito da manipulação da cinemática de corrida (comprimento da passada (CP) e frequência da passada (FP)) durante o aquecimento em performances de sprint repetido de 30m. As principais conclusões do estudo foram: (i) considerando as novas tendências que surgiram, pode-se sugerir efeitos positivos no desempenho após alongamentos curtos seguidos de exercícios específicos de ativação muscular, e após alongamento dinâmico, ambos dependendo da duração e intensidade; esforços máximos de curta duração e específicos para a atividade seguinte, seguidos por poucos minutos de recuperação, fornecem respostas neuromusculares benéficas e melhor desempenho em esforços de alta intensidade e de curto prazo; o aquecimento passivo durante a fase de transição entre o aquecimento e a tarefa principal leva à otimização do desempenho subsequente; (ii) houve efeitos benéficos do aquecimento no sprint de 30m e 100m; (iii) a corrida de 100m é igualmente otimizada após o aquecimento com ou sem potenciação pós-ativação, mas com cinemática de corrida diferente; (iv) os efeitos positivos do aquecimento nos 30m de corrida foram causados por 15m iniciais mais rápidos e maior CP nos últimos 15m de prova; (v) não foram encontrados efeitos adicionais nos 30m após a inclusão de exercícios balísiticos durante o aquecimento; (vi) um aquecimento focado em maior CP ou maior FP não resultou em diferenças no desempenho e cinemática nos 30m sprint, apesar de terem ocorrido diferentes estratégias de corrida (fase inicial mais rápida após aquecimento estilmulando FP e fase final mais rápida após aquecimento estimulando CP); (viii) os resultados destacaram a resposta individual a cada procedimento de aquecimento. As principais conclusões deste trabalho enfatizam a importância do desenho do aquecimento para distâncias curtas e a necessidade de individualização para desempenhos otimizados. Outros estudos são necessários para entender profundamente seus efeitos sobre o desempenho

Australia apuesta por reforzar el mundo digital y la advocacy en la práctica de la ByD

In 2013, the ALIA, the Australian Library and Information Association prepared for the first time the report Future of the library and information science profession, of which we already made a first review in this same space. From this first report, the ALIA was receiving opinions and answers that have been drawing a whole series of new objectives and new horizons for the profession. Thus, this feedback has allowed us to identify new topics, new challenges and new actions that the profession must face, and which have resulted in an update of the original report, dated May 2017; this time, but in seven sectoral reports, much more specific and focused on a more precise field: the profession in general; the professionals; the associations and entities of the sector; public libraries; specialized libraries; school libraries; and finally university libraries. All these sector reports follow the same structure

Effect of moment marketing and brand sponsorship in brand equity and customer engagement

To follow the needs of customer of having the information the faster they can, brands are adopting a new strategy called moment marketing, which is a challenge for customers but, if well performed, can bring several benefits. To develop this strategy, social media are used to produce and share contents. Related with this moment marketing strategy, there are some events that can triggers the perfect opportunity to engage like football championships that has associated with them sponsorship agreements which helps it to gain visibility. Focusing on this strategy to interact with customers, the purpose of this study was to investigate if content created in real-time, when influenced by brand sponsorship, have impact in the constructs of brand equity and customer engagement. To study sponsorship agreements, it is important to explore brands that are not sponsors but still perform their marketing activities related with the event – this is called ambush marketing. The experimental study evaluated a total of 303 respondents and data collection was carried out via online-survey. The results of the experimental study revealed no significant differences exists between the groups under study in terms of brand awareness, brand image and customer engagement. However, the results related with brand loyalty were different between the two groups in moment marketing condition. Regarding few existing literature, this research provides new insights on the effects that brand sponsorship in moment marketing has on brand equity and consumer engagement constructs. This study acts as preliminary research in this field and thus has great scientific relevance.Devido aos consumidores quererem informação o mais rápido, as marcas têm adotado uma estratégia em moment marketing que é um grande desafio para o marketing, mas, quando bem executada, pode representar diversos benefícios. Para isso, as redes sociais são utilizadas para produzir e partilhar conteúdo. Há eventos que podem ajudar na criação de conteúdo em tempo real para interagir, como por exemplo, os campeonatos de futebol, sendo que estes tipos de eventos geralmente têm acordos que os ajudam a ganhar visibilidade. O objetivo deste estudo foi então investigar se o conteúdo criado em tempo real, quando influenciado por um acordo de patrocinador oficial, tem impacto na construção de brand equity e interação com o consumidor. É preciso também explorar o conceito das marcas que não são patrocinadores oficiais e utilizam o evento nas suas estratégias de marketing – chamase a isto ambush marketing. A experiência avaliou um total de 303 respondentes e a recolha dos dados foi feita via um questionário online. Os resultados revelaram que não há diferenças significativas entre os grupos estudados no que toca a brand awareness, brand image e interação com o consumidor. Apesar disso, o resultado relacionado com a lealdade da marca revelou diferenças entre os grupos patrocinadores e não patrocinadores em tempo real. Apesar da pouca literatura, esta pesquisa providencia novos insights sobre os efeitos que uma marca patrocinadora pode ter na brand equity e na interação com o consumidor. Como tal, este estudo atual como uma pesquisa preliminar neste campo e pode ter grande relevância científica

Cotton gauze bandage: a support for protease immobilization for use in biomedical applications

The covalent immobilization of trypsin on sterilized cotton gauze bandage was carried out for future use as an anti-inflammatory agent on wound dressing. The optimal immobilization conditions were determined: the influence of pH, concentration, and volume of the trypsin solution used in the immobilization procedure was studied. The catalytic properties and kinetic parameters, as well as the storage stability of the immobilized and free enzyme were compared. Results showed that the optimal pH and temperature for the immobilized trypsin in the hydrolysis of N-benzoyl-DL-arginine p-nitroanilide were 9.5 and 55 ºC, which were higher than those of the free form (7.5 and 45 ºC). It was found, at 37 ºC and pH 7.0 (approximately, the physiological conditions), that the Km (Michaelis constant) was 3.98 µmol/mL and that Vmax (maximal reaction rate) was 0.719 µmol/(min mg) for the immobilized trypsin, compared to a Km of 2.46 mmol/mL and a Vmax of 2.89 µmol/(min mg) for the free trypsin. The amount of immobilized trypsin was 6 mg/g dried support. After 30 days, no trypsin had liberated from the support. The superior performance of the immobilized trypsin demonstrates its potential application in practice.Neste trabalho foi efetuada a imobilização de tripsina numa gaze esterilizada de algodão. Foram determinadas as condições ótimas de imobilização: foi estudada a influência do pH, concentração e volume da solução de tripsina usada na imobilização na hidrólise da N-benzoil-DL-arginina p-nitroanilida. As propriedades catalíticas, os parâmetros cinéticos e as condições de estabilidade das enzimas livre e imobilizada foram comparadas. Os resultados mostraram que o pH e a temperatura ótimos para a tripsina imobilizada foram 9.5 e 55 ºC, respectivamente, maiores que os correspondentes da forma livre (7,5 e 45 ºC). A 37 ºC e a pH 7,0 (aproximadamente as condições fisiológicas) Km (constante de Michaelis) foi 3,98 µmol/mL e Vmax (velocidade máxima de reacção) foi 0,719 µmol/(min mg) para a tripsina imobilizada; para a tripsina livre os valores correspondentes foram 2,46 µmol/mL e 2,89 µmol/(min mg). A quantidade de enzima imobilizada foi de 6 mg/g (base seca). Após 30 dias não se verificou libertação de tripsina do suporte. O bom desempenho da tripsina imobilizada na gaze esterilizada de algodão comprova a sua potencial utilização como agente anti-inflamatório no tratamento de lesões cutâneas

Expected, unexpected, good and bad aggregate uncertainty

We study aggregate uncertainty and its linear and nonlinear impact on real and financial markets. By distinguishing between four general notions of aggregate uncertainty (good-expected, bad-expected, good-unexpected, bad-unexpected) within a simple, common framework, we show that it is bad-unexpected uncertainty shocks that generate a negative reaction of economic variables (such as investment and consumption) and asset prices. Our results help to elucidate the real, complex nature of uncertainty, which can be both a backward- or forward-looking expected or unexpected event, with markedly different consequences for the economy. We also document nonlinearities in the propagation of uncertainty to both real and financial markets, which calls for the close monitoring of the evolution of uncertainty so as to help mitigate the adverse effects of its occurrenc

Expected, Unexpected, Good and Bad Uncertainty

By distinguishing between four general notions of uncertainty (good expected, bad-expected, good-unexpected, bad-unexpected) within a common and simple framework, we show that it is bad-unexpected uncertainty shocks that generate a negative reaction of macroeconomic variables (such as investment and consumption), and asset prices. Other notions of uncertainty might produce even positive responses in the macroeconomy. We also show that small uncertainty shocks might have larger impacts on economic activity and financial markets than bigger shocks between one to three years after its realization. We explore the time and magnitude of uncertainty shocks by means of a novel distributed lag nonlinear model. Our results help to elucidate the real and complex nature of uncertainty, which can be both a backward or forward-looking expected or unexpected event, with markedly different consequences for the economy. They have implications for policy making, asset pricing and risk management

Learning Rational Numbers through an Emergent Modeling Process enhanced by Percentage

In this paper, a discussion about how elementary students’ conceptual understanding of rational numbers is fostered, along with number sense development, in a sociocultural learning perspective, is carried out. We highlight how an emergent modeling process, enhanced by percentage and supported by multiple representations, emphasizing numerical values of magnitude contexts, may contribute to that understanding. A classroom experiment was developed, following the methodological procedures of a Design Research. We analyze student’s interactions and their work, as representations are used and transformed as models. Findings suggest that percentage, associated to students’ real world experiences and previous knowledge, is intuitive and seems to be helpful in students’ numerical development from whole numbers to rational numbers. In a classroom community that supports a co-participated learning, where multiple representations serve and become models as dynamic process, can be a way to reach the meaning of rational number’s concepts and to strength interrelationships between those concepts.info:eu-repo/semantics/publishedVersio
