Promover a partir do interior: o papel do facilitador no apoio a formas dialógicas e reflexivas de auto-avaliação

Resumo Este artigo apresenta uma abordagem reflexiva e dialógica para a avaliação que tem sido desenvolvida ao longo de cerca de vinte anos por um grupo de pesquisa em educação na Universidade de Pavia e que foi testado em campo em várias experiências e pesquisas realizadas na Itália, em que educadores de creches e escolas de educação infantil estiveram diretamente envolvidos. A abordagem, inspirada na avaliação de quarta geração de Guba e Lincoln e na teoria do pensamento reflexivo de Dewey, considera a avaliação como um processo pelo qual as pessoas que trabalham em uma instituição de ensino podem refletir em grupo sobre suas crenças e práticas educacionais, a fim de planejar e implementar ações de melhora. Depois de delinear brevemente os principais benefícios da abordagem, vou me concentrar no papel desempenhado nela pela figura dofacilitador, alguém de fora da realidade educacional objeto de avaliação, cuja principal tarefa é ajudar os participantes a reconstruir uma imagem compartilhada da realidade em que operam, o que torna possível prever o futuro, pensando em por que você faz o que você faz e como você pode melhorar isso. O principal objetivo dessa figura é “promover a partir de dentro” provocando, através da reflexão, o “empoderamento” de grupos de educadores e professores. Com base em uma pesquisa recente, as estratégias comunicativas e maiêuticas utilizadas por essa figura na promoção de processos de auto-avaliação em grupos de educadores e professores também serão apresentados

Experimental design in Behavior Analysis: discussion on its use in inclusive educational interventions

A aplicação de intervenções educacionais inclusivas por agentes educacionais em estudantes da educação especial deveria ser sistematicamente avaliada, para garantir replicação futura dos procedimentos e resultados, a partir do uso de um delineamento experimental adequado à proposta. O objetivo foi analisar como pesquisas aplicadas podem contribuir no arranjo de intervenções educacionais inclusivas mais sistemáticas, a partir do uso de delineamentos experimentais em Análise do Comportamento; discutir a tomada de decisão para a escolha de um delineamento e o impacto dessa escolha nos dados coletados e no conhecimento que se deseja produzir, especialmente a partir do envolvimento dos diferentes agentes educacionais na aplicação de intervenções pedagógicas com estudantes com DI ou TEA.

The Iceman as a Burial

Since his discovery in 1991 the iceman has been widely seen as meeting a dramatic end – mortally wounded by an arrow shot while attempting to flee through an Alpine pass. A careful study of all the located grave goods, here planned comprehensively for the first time, points strongly towards the scene as one of a ceremonial burial, subsequently dispersed by thawing and gravity. The whole assemblage thus takes on another aspect – not a casual tragedy but a mortuary statement of its day

Synergic strategies to improve the PBF-LB/M processability of a cracking-sensitive alloy

The Powder Bed Fusion-Laser Beam\Metals (PBF-LB\M) is a promising additive manufacturing process that can be used to directly produce functional components with a complex shape for a wide variety of applications. However, the layer-by-layer scanning and high cooling rates result in a high thermal gra- dient and thus, in thermally induced stresses. The stresses developed during the additive process could lead to undesirable cracking and delamination phenomena that can seriously affect the performance of the final component. The alloy composition can exacerbate crack and delamination formation, however, the need to expand the portfolio of high-strength materials processable for PBF-LB\M makes the resolu- tion of these undesirable phenomena a primary challenge in the additive manufacturing field. This works aims to systematically investigate some strategies to make processable non-standard compositions. As no standard compositions, the promising pre-alloyed AlSi10Cu8Mg composition was chosen for the present work. Based on the results obtained from a condition of severe delamination, the synergetic use of appro- priate process parameters and support structures can lead to crack-free and fully dense specimens also when platform heating is not allowed. The developed approach could also be applied to adapt other cracking-sensitive alloys for PBF-LB\M production

Advantages of additive manufacturing for biomedical applications of polyhydroxyalkanoates

In recent years, biopolymers have been attracting the attention of researchers and special-ists from different fields, including biotechnology, material science, engineering, and medicine. The reason is the possibility of combining sustainability with scientific and technological progress. This is an extremely broad research topic, and a distinction has to be made among different classes and types of biopolymers. Polyhydroxyalkanoate (PHA) is a particular family of polyesters, synthetized by microorganisms under unbalanced growth conditions, making them both bio-based and biodegradable polymers with a thermoplastic behavior. Recently, PHAs were used more intensively in biomedical applications because of their tunable mechanical properties, cytocompatibility, adhesion for cells, and controllable biodegradability. Similarly, the 3D-printing technologies show increasing potential in this particular field of application, due to their advantages in tailor-made design, rapid prototyping, and manufacturing of complex structures. In this review, first, the synthesis and the production of PHAs are described, and different production techniques of medical implants are compared. Then, an overview is given on the most recent and relevant medical applications of PHA for drug delivery, vessel stenting, and tissue engineering. A special focus is reserved for the inno-vations brought by the introduction of additive manufacturing in this field, as compared to the traditional techniques. All of these advances are expected to have important scientific and commer-cial applications in the near future

Development of glass-stalks-unsaturated polyester hybrid composites

The aim of this study is to investigate the possibility to use agro-residues of the vinification process as a cheaper and eco-friendly fillers to prepare unsaturated polyester composites for interior design building sector. Experimental unsaturated polyester–based resin composite samples, reinforced with grape stalks, were prepared by a simple casting technique. The glass microspheres were added in the mixing to increase the mechanical and physical properties of the final materials. A silane coupling agent was used to increase the interface adhesion between resin and grape stalks. The samples were subjected to several tests. Unfilled samples were analyzed by Differential Scanning calorimetry (DSC). Prepared silanized and non-silanized composites were completely characterized in order to study the effect of stalk fibers concentration on the mechanical, chemical and physical properties. The results showed that mechanical and physical properties for silanized composites were superior to non-silanized composites. The presence of stalks, up to 50% wt. increased Young's Modulus preserving a satisfactory tensile strength and hardness in comparison with the neat resin properties. Then, the final results showed that grape stalks from winemaking can be satisfactory used as natural filler resource to produce composites for interior furniture

A new noninvasive method for the accurate and precise assessment of varicose vein diameters

The feasibility and reproducibility of a new ultrasonic method for the direct assessment of maximal varicose vein diameter (VVD) were evaluated. A study was also performed to demonstrate the capacity of the method to detect changes in venous diameter induced by a pharmacologic treatment. Patients with varicose vein disease were recruited. A method that allows the precise positioning of patient and transducer and performance of scans in a gel-bath was developed. Maximal VVD was recorded both in the standing and supine positions. The intraassay reproducibility was determined by replicate scans made within 15 minutes in both positions. The interobserver variability was assessed by comparing VVDs measured during the first phase baseline examination with those obtained during baseline examinations in the second phase of the study. The error in reproducibility of VVD determinations was 5.3% when diameters were evaluated in the standing position and 6.4% when assessed in the supine position. The intramethod agreement was high, with a bias between readings of 0.06 ±0.18 mm and of –0.02 ±0.19 mm, respectively, in standing and supine positions. Correlation coefficients were better than 0.99 in both positions. The method appears to be sensitive enough to detect small changes in VVDs induced by treatments. The proposed technique provides a tool of potential valid use in the detection and in vivo monitoring of VVD changes in patients with varicose vein disease. The method offers an innovative approach to obtain a quantitative assessment of varicose vein progression and of treatment effects, thus providing a basis for epidemiologic survey
