Cutting without Cursing: A Successful Cancellation Project     

Beatriz Betancourt Hardy  Martha C. Zimmerman  Laura A. Hanscom 《期刊图书馆员》2016,71(2):112-120

The Salisbury University Libraries embarked on a serials and database cancellation project in the 2014–2015 academic year, eventually cutting nearly 20% of journals without causing any faculty protests. Picking up ideas from numerous other libraries, the three-person project task force developed a three-stage process: 1) preparation—gathering data and laying the groundwork for getting feedback; 2) getting feedback from liaisons, faculty, and departments; and 3) making decisions about what to cut and sharing the results. This article details the steps taken and key recommendations for other libraries undertaking similar projects.  相似文献   

Speaking Q’anjobal,Spanish, and English: a world where other worlds are possible     

Beatriz Eugenia Guerrero-Arias 《Diaspora, Indigenous, and Minority Education》2019,13(3):133-145

Currently, there is a call for more humane ways in humanities, for transitions to a world where other worlds are possible. This qualitative case study analyzes an emergent translingual boy’s participation in diverse spatial repertoires to address issues of learning and community belonging. José is a 4-year-old preschool Guatemalan-ancestry boy, who speaks Q’anjob’al, Spanish, and English. He was placed in an English classroom with daily 30-min Spanish and English pullout. José participated in the pullout to a desirable extent but was marginalized in the English classroom. At home, José had varied opportunities for participating in diverse spatial repertoires. I discuss how home and school have different conceptions of learning and community belonging, and how the home setting with pluriversed spatial repertoires sheds light on a pedagogical practice aimed at transitioning towards a world where other worlds are possible.  相似文献

Developing an Initial Learning Progression for the Use of Evidence in Decision-Making Contexts     

Beatriz Bravo-Torija  María-Pilar Jiménez-Aleixandre 《International Journal of Science and Mathematics Education》2018,16(4):619-638

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   

Modeling the appeal of movie features to demographic segments of theatrical demand     

Ignacio Redondo  Morris B. Holbrook 《Journal of Cultural Economics》2010,34(4):299-315

Various studies have built models, using aggregate box-office data, to predict the contribution of a motion picture’s features to its theatrical demand. But such an approach fails to represent the heterogeneous influence of movie features on demographic groups and is unable to assist market-segmentation decisions. We propose and illustrate a new approach for modeling the appeal of movie features to market segments via the use of appropriate individual-specific data and canonical correlation analysis. Specifically, through demographically detailed movie-attendance data available in Spain, we build a model of how movie features influence the demographic composition of audiences. Via a canonical correlation analysis, we identify four dimensions underlying the relationships between several movie features (country of origin, genre, objectionable content, stars, promotional effort, and critical evaluations) and audience demographics (gender, age range, presence of children, education, social class, and size of municipality). These dimensions represent the strong pairings between four moviegoer demographic profiles and four movie-feature profiles. Our approach can potentially aid in segmentation and green-lighting decisions by matching movie features with the most relevant segment-specific preferences.  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
