Response to large-scale emergencies is a cooperative process that requires the active and coordinated participation of a variety of functionally independent agencies operating in adjacent regions. In practice, this essential cooperation is sometimes not attained or is reduced due to poor information sharing, non-fluent communication flows, and lack of coordination. We report an empirical study of IT-mediated cooperation among Spanish response agencies and we describe the challenges of adoption, information sharing, communication flows, and coordination among agencies that do not share a unity of command. We analyze three strategies aimed at supporting acceptance and surmounting political, organizational and personal distrust or skepticism: participatory design, advanced collaborative tools inducing cognitive absorption, and end-user communities of practice. 相似文献

This article discusses forms of arts‐based mediation in museums that use creation as the primary tool in the learning process. We present four mediation experiences based on the arts‐based teaching methodologies promoted by the project ‘Art for Learning Art’. These experiences have been developed in four museums: the Centre Pompidou Málaga, the State Russian Museum in Málaga and the Espai d'Art Contemponeo [Center of contemporary art] in Castellón in Spain and the Modern Art Murilo Mendes Museum of Minas Gerais in Brazil. Four experiences in three cities of two countries that work in a methodology which involves participative and collaborative visitor connections with the works exhibited using arts‐based strategies. In all cases, the artistic works of the exhibitions are the conceptual basis for mediation proposals that are offered to the public in order to encourage participation. We link the aesthetic experience as the origin of the mediation process in two fundamental aspects: creation and appreciation. In the act of creative appreciation, most art education objectives are met. The actions and processes are directed by collaborative and contemporary creation strategies around two axes: museum educator‐artists in training and visitors‐artists as learners. In the four experiences that we present here, this confluence takes place. The four events have been adapted to the conditions of the place, public and art exhibitions, contributing new approaches to the model that has been promoted from the University of Granada since 2013. 相似文献

La enseñanza de lenguas extranjeras está experimentando un «enriquecimiento curricular» muy positivo. De considerarse como un simple instrumento vehicular de conocimientos o comunicación, las lenguas extranjeras están pasando a conectarse con el gran problema social y cultural de conocer otros pueblos, de conocer el mundo. El objetivo-medio de la globalización (con ciencias sociales principalmente pero no sólo) se convierte así en uno de los puntos fuertes de la enseñanza de otras lenguas. 相似文献

Introduction
Technological innovation requires the laboratories to ensure that modifications or incorporations of new techniques do not alter the quality of their results. In an ISO 15189 accredited laboratory, flexible scope accreditation facilitates the inclusion of these changes prior to accreditation body evaluation. A strategy to perform the validation of a biochemistry analyzer in an accredited laboratory having a flexible scope is shown.Materials and methods:
A validation procedure including the evaluation of imprecision and bias of two Dimension Vista analysers 1500 was conducted. Comparability of patient results between one of them and the lately replaced Dimension RxL Max was evaluated. All studies followed the respective Clinical and Laboratory Standards Institute (CLSI) protocols. 30 chemistry assays were studied. Coefficients of variation, percent bias and total error were calculated for all tests and biological variation was considered as acceptance criteria. Quality control material and patient samples were used as test materials. Interchangeability of the results was established by processing forty patients’ samples in both devices.Results:
27 of the 30 studied parameters met allowable performance criteria. Sodium, chloride and magnesium did not fulfil acceptance criteria. Evidence of interchangeability of patient results was obtained for all parameters except magnesium, NT-proBNP, cTroponin I and C-reactive protein.Conclusions:
A laboratory having a well structured and documented validation procedure can opt to get a flexible scope of accreditation. In addition, performing these activities prior to use on patient samples may evidence technical issues which must be corrected to minimize their impact on patient results. 相似文献19.

Calibration, or the correspondence between perceived performance and actual performance, is linked to students’ metacognitive and self-regulatory skills. Making students more aware of the quality of their performance is important in elementary school settings, and more so when math problems are involved. However, many students seem to be poorly calibrated, with a tendency towards over-confidence. The present study analyzes the relationship between post-performance calibration accuracy and the metacognitive process shown by 524 fifth- and sixth-grade students while solving two math problems. After calculating a calibration index and establishing the stability of students’ judgments and actual performance, differences in the metacognitive process exhibited by students with different calibration accuracy (Accurate vs. Inaccurate groups) were analyzed. The emergence of different calibration patterns and differences in the metacognitive process as a function of mathematics achievement and grade level were also examined. Results indicated that: (a) students in the overall sample were little calibrated and over-confident, showing high stability in their judgments and actual performance across problems; (b) inaccurate students reported using information representation sub-processes (drawing/summarizing) less frequently, but writing and reviewing (and also correcting mistakes) more frequently than their accurate peers; and (c) differences in calibration patterns and the metacognitive process were found when achievement level was considered, whereas grade level did not generate any important effect. These findings suggest the usefulness of process-based measures to examine the metacognitive processes involved in making post-performance judgments, considering achievement and its possible mediating role in this relationship. 相似文献
