This article presents the intervention process carried out on a work of art created by artist Yolanda Gutiérrez Acosta, using a series of ephemeral materials such as butterfly wings and agave thorns. The work, an installation from 2002, is entitled ‘Efímeras’ (‘Ephemera’) and consists of 12 flowers mounted on acetate sheets and attached to the same with vinyl acetate copolymers and acrylic acid esters (Mowilith®). These flowers are installed on the floor in a bed of dried flowers. The conservation of contemporary art can lead to some previously unimaginable problems for restorers. Current works of art are somewhat material in nature, but they also have a conceptual dimension that is essential for their artistic interpretation. The artist’s participation in the decision-making process prior to the restoration was quite useful. The passage of time, its effect on the work, and the need to understand the possibility of the demise and destruction of the work were implicit as of the onset of its creation, such that, according to the artist, we are forced to reflect upon the possibilities of its future state. 相似文献
The purpose of this study was to investigate the effects of interval aerobic training combined with strength exercise in the same training session on body composition, and glycaemic and lipid profile in obese rats. Sixteen lean Zucker rats and sixteen obese Zucker rats were randomly divided into exercise and sedentary subgroups (4 groups, n = 8). Exercise consisted of interval aerobic training combined with strength exercise in the same training session. The animals trained 60 min/day, 5 days/week for 8 weeks. Body composition, lipid and glycaemic profiles and inflammatory markers were assessed.
Results showed that fat mass was reduced in both lean and obese rats following the exercise training (effect size (95% confidence interval (CI)) = 1.8 (0.5–3.0)). Plasma low-density lipoprotein–cholesterol and fasting glucose were lower in the exercise compared to the sedentary groups (d = 2.0 (0.7–3.2) and 1.8 (0.5–3.0), respectively). Plasma insulin was reduced in exercise compared to sedentary groups (d = 2.1 (0.8–3.4)). Some exercise × phenotype interactions showed that the highest decreases in insulin, homeostatic model assessment-insulin resistance, fasting and postprandial glucose were observed in the obese + exercise group (all, P < 0.01). The findings of this study suggest that interval aerobic training combined with strength exercise would improve body composition, and lipid and glycaemic profiles, especially in obese rats. 相似文献
Results are reported in this paper from a study aimed at evaluating significant competencies in final-year students of some engineering programmes in Chile. The study was carried out by a group of eight universities that were interested in exploring ways to assess learning outcomes such as those demanded by the recent Chilean accreditation system. The authors actively participated in all stages of the study, contributing directly to the design, application and results evaluation of some tests. A sample of 150 students was tested, under conditions that guaranteed the comparability of results. In this paper the authors present results relating to the evaluation of effective communication. The study was backed up by a conceptual model and some hypotheses that are explained and discussed in this work. 相似文献
The aims of this study were (a) to determine whether Spanish children with reading disabilities (RD) show a speech perception deficit and (b) to explore the locus and nature of this perceptive deficit. A group of 29 children with RD, 41 chronological age-matched controls, and 27 reading ability-matched younger controls were tested on tasks of speech perception. The effect of linguistic unit (word vs. syllable) and type of phonetic contrast (voicing, place and manner of articulation) were analyzed in terms of the number of errors and the response time. The results revealed a speech perception deficit in Spanish children with RD that was independent of the type of phonetic contrast and of linguistic unit. 相似文献

This paper pertains to a broader biographical-narrative research project which studies barriers and support as identified by students with disabilities at a Spanish University (Barriers and Support That Disabled Students Identify in the University. Project funded by the Spanish Ministry of Science and Innovation (Dir. Dr Anabel Moriña; Ref. EDU 2010–16264, 2010–2014)). The present study focuses specifically on barriers and support identified by students with disabilities enrolled in undergraduate programmes in the Social Sciences and Law. The purpose of this paper is to analyse, from the point of view of disabled students (applying the biographic-narrative methodology), which barriers and which support this group encounters in Higher Education. To this end, findings are organised in the following categories: general institutional data; infrastructure, architectural and accessibility-related data; faculty and teaching-related data; data relating to fellow students; and suggestions for improving the university and/or university classrooms. In the Conclusions section, we return to our earlier discussion of key findings which shed some light on how the University helps or hinders learning among participants in the study. From this perspective, taking as a reference the social model of disability, we conclude that in order to be inclusive, the University needs to commit itself to adopting proactive measures that eliminate the barriers that do not permit the learning and the full participation of the students in question. 相似文献
An on-going challenge in teacher education programs is how best to support new teachers in connecting their university coursework with their professional identity development and pedagogical practice in the schools. The reading and writing of case studies is one promising strategy teacher educators have explored as a means of assisting teachers in developing and cultivating a self-reflective, theory and practice reflexive, style of learning in the teacher education classroom and beyond. In the present paper, I present a case study of my own journey as a developmental and educational psychologist responsible for co-teaching a secondary teacher education course called "Adolescent Development for Teachers", in which having student-teachers research and write-up a case study of a single adolescent became the focus of the course and our pedagogy. I describe events that brought about the use of the case study in the course, the influence the use of the case study had on myself as an instructor as well as the students, and what students say are the educational benefits and difficulties of completing the adolescent case study. Implications for infusing a developmental focus into teacher education programs are discussed. 相似文献
Within modular degrees it is sometimes possible for students to broaden their education by taking modules from outside their main programme of study. This is one significant aspect of modular degrees which has not been studied. In an effort to better understand this issue, the research reported in this paper explored the experiences: (1) of students taking modules from outside their programme of study and; (2) of staff teaching modules with significant numbers of students from other programmes. In total, 820 undergraduate students responded to an on-line survey; 12 academic staff members participated in interviews. The survey focused on students’ reasons for choosing the module, their experiences of assessment and their perceptions of workload. Interviews with academic staff focused on the influence of non-programme students on teaching and assessment practices. The discussion addresses the implications of student choice and classroom diversity for teaching and assessment in modular systems. 相似文献
