Formação continuada: seus impactos na prática docente: um olhar sobre o programa pró-letramento

RESUMO: A preocupação central desta pesquisa foi compreendermos qual o impacto da formação continuada Pró-Letramento na prática pedagógica do professor a partir das necessidades e desafios do cotidiano escolar. Buscamos conhecer o conceito que os sujeitos da pesquisa têm sobre formação continuada, abordando a mesma como elemento da prática docente, comparamos o cotidiano de sala de aula de professores que passaram pela formação Pró-Letramento com os que não tiveram acesso a essa formação. Com respeito à formação continuada a percebemos como um processo dinâmico, reflexivo, que combina uma variedade de possibilidades e modalidades de aprendizagens, em que o professor vai adequando a sua formação às exigências sociais, culturais, educacionais. A formação continuada se dá, por meio da reflexão sobre a própria prática profissional no processo de ação-reflexão-ação, adquirindo significado na medida em que desenvolve e promove os diversos saberes docentes. A pesquisa foi conduzida com 90 professores do Ensino Fundamental – Anos Iniciais -, com oito coordenadoras que acompanham pedagogicamente os professores sujeitos dessa pesquisa e a observação em sala de aula. Procedeu-se à aplicação de um questionário validado e adaptado aos professores e uma entrevista aos coordenadores. A análise dos dados quantitativos foi realizada por meio do programa SPSS; enquanto a análise dos dados qualitativos foi orientada pela análise de discurso. A pesquisa aponta para algumas conclusões no que se refere a importância da Formação Continuada Pró-Letramento, tendo em vista a mesma possibilitar mudanças na prática pedagógica e colaborara para formação de um professor reflexivo, ao mesmo tempo que abre espaço para novos questionamentos e novos estudos.ABSTRACT: The central concern of this research was to understand the impact of the continuing education pro-literacy teaching practice from the teacher‘s needs and challenges of every day school life. We tried to know the concept that the subjects have on continuing education, addressing it as part of teaching practice, we compared the daily classroom teachers who have gone through training with Pro-Literacy did not access to such training. With respect to continuing education perceive it as a dynamic, reflective, which combines a variety of possibilities and modalities oF learning, the teacher will tailoring the training requirements to social, cultural, educational. The continuing education takes place, through reflection on own practice in the process of action-reflection-action, acquiring significance in that it develops and promotes the various teacher‘s knowledge.

A influência da competência emocional no desempenho académico de adolescentes do ensino secundário

O nosso trabalho tem como objectivo principal responder à questão fundamental: A competência emocional influencia o desempenho académico em adolescentes do ensino secundário? Para o efeito, os instrumentos utilizados foram: o questionário de Competência Emocional, adaptado ao contexto português por Lima Santos e Faria (2001), as pautas de notas dos alunos tendo em vista identificar o género, ano escolar e as idades dos alunos. Depois de obtida a autorização para a utilização do questionário, procedemos à sua aplicação sendo que a amostra foi constituída por 191 estudantes a frequentar o Ensino Secundário na Escola Secundária Dr. João de Araújo Correia, com idades compreendidas entre os 14 e 19 anos, no início do ano letivo, setembro de 2011. Após a recolha de dados procedemos à sua análise, a partir do programa SPSS, versão 19.0 para o Windows, cingindo-nos à análise descritiva das variáveis Género, Idade e Ano Escolar; análise descritiva da turma; análise descritiva das notas da disciplina de português e matemática; análise descritiva das questões do questionário de competência emocional; análise descritiva das dimensões do questionário; comparação de Médias das três Dimensões do questionário de competência emocional; análise de Regressão Linear e análise de Médias Através dos Itens e Variáveis Sociodemográficas e Escolares. Os resultados apontaram para a existência de diferenças estatisticamente significativas em relação à nota de Português no que diz respeito à EE (Expressão Emocional). Os alunos cujas notas de português são mais baixas apresentam valores mais baixos também na EE. Por outro lado, a nota de matemática era a única preditora da EE, explicando 4.3% da variância. Assim, a relação entre competência emocional e o desempenho académico verificou-se em relação à dimensão da Expressão Emocional. Por outro lado, em função do género, idade e escolaridade apenas se verificaram diferenças significativas para os itens da Expressão Emocional. Na relação entre o desempenho académico relativamente às disciplinas de português e matemática, comparativamente com a competência emocional apenas se verificou relação na dimensão - Expressão Emocional.

A influência do comprometimento organizacional na satisfação no trabalho em voluntariado

Este trabalho tem como principal objetivo estudar a relação entre o comprometimento organizacional e a satisfação no trabalho em voluntários pertencentes a diferentes organizações de terceiro sector da zona da Grande Lisboa. A amostra em estudo é constituída por 121 voluntários, com idades compreendidas entre os 12 e os 63 anos, de ambos os géneros e com habilitações literárias desde o 4ª ano ao ensino superior. No que concerne à metodologia, é utilizado um questionário que mede o comprometimento organizacional, elaborado por Allen e Meyer (1997) e um inventário sobre a satisfação global com trabalho proposto por Hackman e Oldham (1975). Na análise dos dados utilizou-se o programa estatístico SPSS. Os resultados obtidos confirmam a existência de uma relação entre o comprometimento organizacional e a satisfação global com o trabalho. De entre as dimensões do comprometimento organizacional, aquela que possui um melhor poder preditivo sobre a satisfação global com o trabalho é o comprometimento afetivo, sendo que quanto maior este último maior a satisfação com o trabalho. As implicações teóricas destes resultados são abordadas e discutidas.

Vascular plant diversity and climate change in the alpine zone of the Lefka Ori, Crete

The aim of this study is to analyse the vascular flora and the local climate along an altitudinal gradient in the Lefka Ori massif Crete and to evaluate the potential effects of climate change on the plant diversity of the sub-alpine and alpine zones. It provides a quantitative/qualitative analysis of vegetation-environment relationships for four summits along an altitude gradient on the Lefka Ori massif Crete (1664-2339 m). The GLORIA multi-summit approach was used to provide vegetation and floristic data together with temperature records for every summit. Species richness and species turnover was calculated together with floristic similarity between the summits. 70 species were recorded, 20 of which were endemic, belonging to 23 different families. Cretan endemics dominate at these high altitudes. Species richness and turnover decreased with altitude. The two highest summits showed greater floristic similarity. Only 20% of the total flora recorded reaches the highest summit while 10% is common among summits. Overall there was a 4.96 degrees C decrease in temperature along the 675 m gradient. Given a scenario of temperature increase the ecotone between the sub-alpine and alpine zone would be likely to have the greatest species turnover. Southern exposures are likely to be invaded first by thermophilous species while northern exposures are likely to be more resistant to changes. Species distribution shifts will also depend on habitat availability. Many, already threatened, local endemic species will be affected first.

The adrenal secretory serine protease AsP is a short secretory isoform of the transmembrane airway trypsin-like protease

To further elucidate the role of proteases capable of cleaving N-terminal proopiomelanocortin (N-POMC)-derived peptides, we have cloned two cDNAs encoding isoforms of the airway trypsin-like protease (AT) from mouse (MAT) and rat ( RAT), respectively. The open reading frames comprise 417 amino acids (aa) and 279 aa. The mouse AT gene was located at chromosome 5E1 and contains 10 exons. The longer isoform, which we designated MAT1 and RAT1, has a simple type II transmembrane protein structure, consisting of a short cytoplasmic domain, a transmembrane domain, a SEA (63-kDa sea urchin sperm protein, enteropeptidase, agrin) module, and a serine protease domain. The human homolog of MAT1 and RAT1 is the human AT ( HAT). The shorter isoform, designated MAT2 and RAT2, which contains an alternative N terminus, was formerly described in the rat as adrenal secretory serine protease (AsP) and has been shown to be involved in the processing of N-POMC-derived peptides. In contrast to the long isoform, neither MAT2 and RAT2 ( AsP) contain a transmembrane domain nor a SEA domain but an N-terminal signal peptide to direct the enzyme to the secretory pathway. The C terminus, covering the catalytic triad, is identical in both isoforms. Immunohistochemically, MAT/RAT was predominantly expressed in tissues of the upper gastrointestinal and the respiratory tract - but also in the adrenal gland. Moreover, isoform-specific RT-PCR and quantitative PCR analysis revealed a complex expression pattern of the two isoforms with differences between mice and rats. These findings indicate a multifunctional role of these proteases beyond adrenal proliferation.

Responsiveness to change by standard-form contract drafters: A case study of the FIDIC White Book

Purpose – The purpose of this paper is to focus on the Fédération Internationale des Ingénieurs-Conseils (FIDIC) White Book standard form of building contract. It tracks the changes to this contract over its four editions, and seeks to identify their underlying causes. Design/methodology/approach – The changes made to the White Book are quantified using a specific type of quantitative content analysis. The amended clauses are then examined to understand the nature of the changes made. Findings – The length of the contract increased by 34 per cent between 1990 and 2006. A large proportion of the overall increase can be attributed to the clauses dealing with “conflict of interest/corruption” and “dispute resolution”. In both instances, the FIDIC drafting committees have responded to international developments to discourage corruption, and to encourage the use of alternative dispute resolution. Between 1998 and 2006, the average length of the sentences increased slightly, raising the question of whether long sentences are easily understood by users of contracts. Research limitations/implications – Quantification of text appears to be particularly useful for the analysis of documents which are regularly updated because changes can be clearly identified and the length of sentences can be determined, leading to conclusions about the readability of the text. However, caution is needed because changes of great relevance can be made to contract clauses without actually affecting their length. Practical implications – The paper will be instructive for contract drafters and informative for users of FIDIC's White Book. Originality/value – Quantifying text has been rarely used regarding standard-form contracts in the field of construction.

Bubble-included chocolate: relating structure with sensory response

Bubbles impart a very unique texture, chew, and mouth feel to foods. However, little is known about the relationship between structure of such products and consumer response in terms of mouth-feel and eating experience. The objective of this article is to investigate the sensory properties of 4 types of bubble-containing chocolates, produced by using different gases: carbon dioxide, nitrogen, nitrous oxide, and argon. The structure of these chocolates were characterized in terms of (1) gas hold-up values determined by density measurements and (2) bubble size distribution which was measured by undertaking an image analysis of X-ray microtomograph sections. Bubble size distributions were obtained by measuring bubble volumes after reconstructing 3D images from the tomographic sections. A sensory study was undertaken by a nonexpert panel of 20 panelists and their responses were analyzed using qualitative descriptive analysis (QDA). The results show that chocolates made from the 4 gases could be divided into 2 groups on the basis of bubble volume and gas hold-up: the samples produced using carbon dioxide and nitrous oxide had a distinctly higher gas hold-up containing larger bubbles in comparison with those produced using argon and nitrogen. The sensory study also demonstrated that chocolates made with the latter were perceived to be harder, less aerated, slow to melt in the mouth, and having overall flavor intensity. These products were further found to be creamier than the chocolates made by using carbon dioxide and nitrous oxide; the latter sample also showed a higher intensity of cocoa flavor.

Towards an improved and more flexible representation of water stress in coupled photosynthesis–stomatal conductance models

Coupled photosynthesis–stomatal conductance (A–gs) models are commonly used in ecosystem models to represent the exchange rate of CO2 and H2O between vegetation and the atmosphere. The ways these models account for water stress differ greatly among modelling schemes. This study provides insight into the impact of contrasting model configurations of water stress on the simulated leaf-level values of net photosynthesis (A), stomatal conductance (gs), the functional relationship among them and their ratio, the intrinsic water use efficiency (A/gs), as soil dries. A simple, yet versatile, normalized soil moisture dependent function was used to account for the effects of water stress on gs, on mesophyll conductance (gm) and on the biochemical capacity. Model output was compared to leaf-level values obtained from the literature. The sensitivity analyses emphasized the necessity to combine both stomatal and non-stomatal limitations of A in coupled A–gs models to accurately capture the observed functional relationships A vs. gs and A/gsvs. gs in response to drought. Accounting for water stress in coupled A–gs models by imposing either stomatal or biochemical limitations of A, as commonly practiced in most ecosystem models, failed to reproduce the observed functional relationship between key leaf gas exchange attributes. A quantitative limitation analysis revealed that the general pattern of C3 photosynthetic response to water stress may be well represented in coupled A–gs models by imposing the highest limitation strength to gm, then to gs and finally to the biochemical capacity.

Climate change policy and business climate strategies: EU cement companies' response to climate change and barriers against action

The paper provides a descriptive analysis of the carbon management activities of the cement industry in Europe based on a study involving the four largest producers of cement in the world. Based on this analysis, the paper explores the relationship between managerial perception and strategy with particular focus on the impact of government regulation and competitive dynamics. The research is based on extensive documentary analysis and in-depth interviews with senior managers from the four companies who have been responsible for and/or involved in the development of climate change strategies. We find that whilst the cement industry has embraced climate change and the need for action, their remains much scope for action in their carbon management activities with current effort concentration on hedging practices and win-win efficiency programs. Managers perceive that inadequate and unfavourable regulatory structure is the key barrier against more action to achieve emission reduction within the industry. EU Cement companies are also shifting their CO2 emissions to less developed countries of the South.

An overview of mixed-effects statistical models for second language researchers

As in any field of scientific inquiry, advancements in the field of second language acquisition (SLA) rely in part on the interpretation and generalizability of study findings using quantitative data analysis and inferential statistics. While statistical techniques such as ANOVA and t-tests are widely used in second language research, this review article provides a review of a class of newer statistical models that have not yet been widely adopted in the field, but have garnered interest in other fields of language research. The class of statistical models called mixed-effects models are introduced, and the potential benefits of these models for the second language researcher are discussed. A simple example of mixed-effects data analysis using the statistical software package R (R Development Core Team, 2011) is provided as an introduction to the use of these statistical techniques, and to exemplify how such analyses can be reported in research articles. It is concluded that mixed-effects models provide the second language researcher with a powerful tool for the analysis of a variety of types of second language acquisition data.

Whey protein mouth drying influenced by thermal denaturation

Whey proteins are becoming an increasingly popular functional food ingredient. There are, however, sensory properties associated with whey protein beverages that may hinder the consumption of quantities sufficient to gain the desired nutritional benefits. One such property is mouth drying. The influence of protein structure on the mouthfeel properties of milk proteins has been previously reported. This paper investigates the effect of thermal denaturation of whey proteins on physicochemical properties (viscosity, particle size, zeta-potential, pH), and relates this to the observed sensory properties measured by qualitative descriptive analysis and sequential profiling. Mouthcoating, drying and chalky attributes built up over repeated consumption, with higher intensities for samples subjected to longer heating times (p < 0.05). Viscosity, pH, and zeta-potential were found to be similar for all samples, however particle size increased with longer heating times. As the pH of all samples was close to neutral, this implies that neither the precipitation of whey proteins at low pH, nor their acidity, as reported in previous literature, can be the drying mechanisms in this case. The increase in mouth drying with increased heating time suggests that protein denaturation is a contributing factor and a possible mucoadhesive mechanism is discussed.
