This paper outlines an initial learning progression for the use of evidence to support scientific arguments in the context of decision-making. Use of evidence is a central feature of knowledge evaluation and, therefore, of argumentation. The proposal is based on the literature on argumentation and use of evidence in decision-making contexts. The objective is to develop a construct map describing a trajectory of evidence use in a decision-making context. The levels in the initial learning progression are characterised by students’ performance in practice. The framework is applied to a multiple-case study in 10th grade (66 students), structured around a marine resource management task. Data included audio and video recordings, as well as students’ written artefacts. Five levels of complexity in student performance are described; on the lowest level, students are able to identify and extract information in response to a problem and recognise general features in a set of data; on the uppermost level, they are able to articulate arguments by synthesising evidence from multiple sources and evaluate options based on evidence and scientific content. The framework also shows potential for recognising students’ difficulties in identifying and integrating data and evidence in their justifications and in drawing from domain knowledge to interpret evidence. Implications for educational practice are discussed.  相似文献

Valuing museums as economic engines: Willingness to pay or discounting of cash-flows?     

Beatriz Plaza 《Journal of Cultural Heritage》2010,11(2):155-162

GLobal Art MUseums as Economic Re-activators (GLAMUR) infrastructures are characterized by global media visibility and sheer presence in the communications environment; outstanding architecture by a superstar architect; big blockbuster exhibitions and a large number of visitors; being magnets for tourists; requiring large capital costs (initial construction costs plus ongoing investments) and large operating budgets; expensive advertising and commercialisation strategies; a huge operative risk; and a hope for substantial impact on the local economy. The economic value of cultural assets is defined as the extent to which they generate benefits for society. The aim of this article is to shed light on the valuation of GLAMUR infrastructures and why, and then to valuate the Guggenheim Museum Bilbao (GMB). In fact, the author of this paper argues that economic valuation through an estimate of the Willingness to Pay (WTP) (e.g. contingent valuation), is clearly an insufficient method for valuating a GLAMUR. One possible accurate method could be to calculate the Discounting of Cash-flows (DCF), followed by the discounting of the WTP estimates.  相似文献   

Digital preservation of Brazilian indigenous artworks: Generating high quality textures for 3D models     

Beatriz Trinchão Andrade  Olga Regina Pereira Bellon  Luciano Silva  Alexandre Vrubel 《Journal of Cultural Heritage》2012,13(1):28-39

Three-dimensional (3D) digital preservation aims at generating 3D models of objects that have cultural or scientific value. It allows realistic visualization of objects through virtual museums or scientific applications, and the restoration of the preserved object in case of natural wear or accidents. This work contributes to this research area by presenting a method to improve color texture quality of 3D models obtained from color and depth images of a laser scanner. Although this device offers precise depth information, the resulting color information is still poor and limits the generation of realistic textures. Our approach is to capture photographs of the object with a high-resolution digital camera and use them to generate a new color texture for the 3D model. Our work proposes a practical technique, easy to replicate, to generate high quality textures for 3D models from photographs. The method is composed by three main steps: (1) calibration of the image acquisition devices; (2) data acquisition; and (3) texture generation. In this paper, we detail our color texture generation method and apply it on the digital preservation of many artworks made by native Brazilians (indians) from the Wauja and Karaja communities. These indigenous communities are acknowledged as great ceramic artists, each bearing their own main themes, using a very rich symbolism in their paintings. Their artworks represent important aspects of the native South American culture and their digital preservation is motivated by three main reasons: (1) their fragility; (2) the paintings loose their original appearance with time; and (3) the possibility of extinction of these communities. We present several results of preserved artworks with enhanced quality realistic texture maps. Also, we present a methodology to analyze the quality and accuracy of texture maps. The resulting 3D models can be visualized through a tool we developed to support the virtual exhibit of 3D preserved heritage.  相似文献   

3D preserving xviii century barroque masterpiece: Challenges and results on the digital preservation of Aleijadinho's sculpture of the Prophet Joel     

Beatriz Trinchão Andrade  Caroline Mazetto Mendes  Jurandir de Oliveira Santos  Olga Regina Pereira Bellon  Luciano Silva 《Journal of Cultural Heritage》2012,13(2):210-214

We present our recent efforts in the digital preservation of a set of baroque sculptures made by Antônio Francisco Lisboa, known as O. Aleijadinho, which is an important American baroque artist. The set was made in the beginning of the xix century and is composed of 12 near real sized sculptures, hand-carved in soapstone. These sculptures represent 12 of the 16 prophets from the Holy Bible and are part of a UNESCO World Heritage Site. Our group has been collaborating with UNESCO in a project that aims to preserve all these statues. We hereby present our initial efforts, consisting of the 3D digital preservation of the Prophet Joel sculpture. We developed a complete 3D digital preservation pipeline composed of four main stages: data acquisition, 3D reconstruction, texture generation and 3D model visualization. By evaluating our results in this first sculpture, we discuss the improvements we conceived before applying our pipeline in the remaining ones. Finally, we present the 3D model of the Prophet which registers the sculpture's current state and will be used in restoration, research and educational activities. We believe this contribution may be useful to guide further research on similar scenarios, showing how to avoid some practical mistakes and achieve good results.  相似文献   

Parental beliefs about child development and parental inferences about actions during child-rearing episodes     

Maria José Rodrigo  Beatriz Triana 《European Journal of Psychology of Education - EJPE》1996,11(1):55-78

The way parents’ beliefs on child development support the elaboration of practical inferences during everyday child-rearing episodes was examined. We contrasted two models based respectively on the classical and the connectionist view of schema approaches. According to the classical view, parents activate preformed packages of beliefs in order to produce inferences whereas under the connectionist view, they activate the network of interconnected episodic traces that better fits the information provided by the situation. In the former case, the quality of the inferences depends on the activation of the proper schema whereas in the latter case it depends on the structure of the information given. Two experiments were designed in which parents holding a particular global belief about child development (either constructivism or environmentalism), were presented with a target couple with similar or different views with respect to them. In Experiment 1, constructivist parents bearing in mind the couple’s belief had to judge a set of words describing the couple’s image as parents, their educational goals as well as a number of sentences describing the couple’s child-rearing practices during hypothetical episodes. In Experiment 2, environmentalist parents had to judge the couple’s practices and the amount of information presented about the couple’s ideas as well as its plausibility were manipulated. The results indicate that the accuracy and speed in the production of inferences depends on the information presented in the task. When the information is embedded in episodes and a full, plausible and distinctive account of the couple’s belief are provided, then the production of inferences is performed faster and with more accuracy. The results are discussed in terms of the classical and connectionist views of schema approaches.  相似文献   

Scaramouche Goes to Preschool: The Complex Matrix of Young Children’s Everyday Music     

Beatriz Ilari 《Early Childhood Education Journal》2018,46(1):1-9

This article examines everyday musical practices and their connections to young children’s learning and development, in and through music. It begins with a discussion of music learning in early childhood as a form of participation and levels of intention in learning. Next, conceptions of child that have dominated early childhood music education discourses are discussed, along with other factors that are known to influence children’s musical lives, such as spatiality, repertoires and the politics of participation. Three illustrative vignettes that stem from the author’s experience as an early childhood music educator and researcher are presented throughout the text. Implications for early childhood education are outlined at the end.  相似文献   

Effect of wetted surface area on friction,pressure, wave and total drag of a kayak     

Beatriz B. Gomes  Leandro Machado  Nuno V. Ramos  Filipe A. V. Conceição  Ross H. Sanders  Mário A. P. Vaz 《Sports biomechanics / International Society of Biomechanics in Sports》2018,17(4):453-461

Using theoretical principles, the components of drag (friction D _F, pressure D _PR and wave D _W) of a single-seat kayak were analysed. The purpose was to examine the effect of changes in wetted surface area due to changes in kayaker’s weight and the relative contribution of D _F, D _PR and D _W to the total passive drag as function of velocity. The total passive drag values were based on experimental data collected in a single-seat kayak. Three different kayaker simulated weights were tested – 65, 75 and 85 kg. D _F was the drag component that contributed the greatest percentage (between 60 and 68% at 5.56 m/s the top velocity tested) to the total passive drag for all the velocities tested and simulated weights. D _W was the most affected by the increase in kayaker’s simulated weight, mainly when comparing 65/75 to 85 kg. Results support the importance of a kayak design selection that minimises the kayak’s drag for the individual weight of the kayaker. Also, the results suggest that the path for better hydrodynamic kayak performance should seek changes that can reduce D _F, D _PR and D _W with D _F offering the most potential to reduce passive drag.  相似文献
