This paper explores the public perceptions of genetically modified foods in Colombia in a phase considered germinal: the topic was too novel at the time of research. The analysis covers media, informal conversations, and the word associations made by a sample of residents in the city of Bogotá. The results show that the public capability of associating with the topic, even intuitively, is due to the availability of culture themes, the primary categories that help conceptual elaborations, and the construction of common-sense theories. Three themes are proposed: natural/artificial, tradition/change, and health/disease. It is argued that cultural themes are not only cognitive, but also affectively laden entities, which explains the evaluative force expressed by social beliefs. Acknowledging the relevance of the non-attitude thesis, the author suggests that people associate novel objects with latent cultural meanings, explaining why words, images, and metaphors are readily available in elaborating social knowledge. 相似文献

The Task Force on Foundational Competencies in Educational Measurement has produced a set of foundational competencies and invited comment on the document. The students and faculty at the University of Massachusetts Amherst provide their comments and critique of the proposed competencies. Both students and faculty agree that there needs to be more specificity regarding the purpose of the document, the nature of the data used to produce the document, and the definition of the relevant terms. Additionally, attention should be paid to the international context, and the role of artificial intelligence and machine learning. The authors acknowledge the contribution of the draft of the foundational competencies and look forward to more conversation regarding this topic. 相似文献

This article analyses academics' perceptions of work management and their job satisfaction in Chilean universities, using a multi-level approach (macro, meso and micro) to study changes in the academic environment. It is based on the survey ‘The Academic Profession in the Knowledge-Based Society’ (APIKS) with data from 11 universities and 1258 valid responses. Three groups of academics are identified according to whether they are engaged in research, teaching or a balance of both. The results of the study show that, at the university level, resource allocation favours teaching, while individual recognition tends to favour research. Institutionally, teaching is prioritised because of its economic impact, but individually, research is more highly valued. This picture reflects a hybrid management model, with tendencies towards de-professionalisation in teaching and entrepreneurialisation in research. Despite these pressures, academics report high levels of job satisfaction, an aspect that requires further research. 相似文献

This article presents new research, which has the objective of quantifying the knowledge produced by historical technological innovations in the field of olive oil industrial heritage. It studies inventions related to the mechanical processes of the extraction of olive oil between 1826 and 1966, which are recorded in the Historical Archive of the Spanish Patent and Trademark Office. It uses a new adaptation of the methodology of knowledge management (KM) defined by Nonaka and Takeuchi. We have obtained the knowledge value of each innovation according to the level of technological knowledge registered at the time, while distinguishing between the historical evolution of inventions relating to milling and those relating to pressing. In the first analysis, the results show a recession in the quantitative level of knowledge in the olive oil sector with respect to the technological potential of the time. However, when contrasted with the events relating to industrial heritage at the time, it is possible to account for this technological evolution and prove the validity of the methodology used. The results show that general evolution of the knowledge generated has decreased, particularly in the pressing process, although this is not the case in the milling process. 相似文献

Abstract In this study, we investigated the age-related differences in repeated-sprint ability and blood lactate responses in 134 youth football players. Players from the development programme of a professional club were grouped according to their respective under-age team (U-11 to U-18). Following familiarization, the participants performed a repeated-sprint ability test [6 × 30-m sprints 30 s apart, with active recovery (2.0–2.2 m · s?1) between sprints]. The test variables were total time, percent sprint decrement, and post-test peak lactate concentration. Total time improved from the U-11 to U-15 age groups (range 33.15 ± 1.84 vs. 27.25 ± 0.82 s), whereas no further significant improvements were evident from U-15 to U-18. No significant differences in percent sprint decrement were reported among groups (range 4.0 ± 1.0% to 5.5 ± 2.1%). Post-test peak lactate increased from one age group to the next (range 7.3 ± 1.8 to 12.6 ± 1.6 mmol · l?1), but remained constant when adjusted for age-related difference in body mass. Peak lactate concentration was moderately correlated with sprint time (r = 0.70, P > 0.001). Our results suggest that performance in repeated-sprint ability improves during maturation of highly trained youth football players, although a plateau occurs from 15 years of age. In contrast to expectations based on previous suggestions, percent sprint decrement during repeated sprints did not deteriorate with age. 相似文献

Monoscopically projected three-dimensional (3D) visualization technology may have significant disadvantages for students with lower visual-spatial abilities despite its overall effectiveness in teaching anatomy. Previous research suggests that stereopsis may facilitate a better comprehension of anatomical knowledge. This study evaluated the educational effectiveness of stereoscopic augmented reality (AR) visualization and the modifying effect of visual-spatial abilities on learning. In a double-center randomized controlled trial, first- and second-year (bio)medical undergraduates studied lower limb anatomy with stereoscopic 3D AR model (n = 20), monoscopic 3D desktop model (n = 20), or two-dimensional (2D) anatomical atlas (n = 18). Visual-spatial abilities were tested with Mental Rotation Test (MRT), Paper Folding Test (PFT), and Mechanical Reasoning (MR) Test. Anatomical knowledge was assessed by the validated 30-item paper posttest. The overall posttest scores in the stereoscopic 3D AR group (47.8%) were similar to those in the monoscopic 3D desktop group (38.5%; P = 0.240) and the 2D anatomical atlas group (50.9%; P = 1.00). When stratified by visual-spatial abilities test scores, students with lower MRT scores achieved higher posttest scores in the stereoscopic 3D AR group (49.2%) as compared to the monoscopic 3D desktop group (33.4%; P = 0.015) and similar to the scores in the 2D group (46.4%; P = 0.99). Participants with higher MRT scores performed equally well in all conditions. It is instrumental to consider an aptitude–treatment interaction caused by visual-spatial abilities when designing research into 3D learning. Further research is needed to identify contributing features and the most effective way of introducing this technology into current educational programs. 相似文献

AbstractThis paper focuses on the design and application of a teacher training strategy to promote the inclusive education of students with disabilities in the science classroom, through the creation of adult learning environments grounded on the principles of dialogic learning. Participants of the workshop proposal consisted of a group of twelve teachers who were working at various educational levels. Teacher teams proposed and implemented in their classroom, innovative, inclusive science-learning activities about a topic of their choice. Data were collected from interviews with teachers five months after the courses, teachers’ portfolios about their practice during implementation of such sequences, and researchers’ observations. The data suggest that it is possible to stimulate a gradual transformation of teaching practices through a teacher training proposal that promotes self-awareness and critical reflection, situated in the creation of meaning and a willingness to change in the spirit of solidarity and social action. We found elements to recommend the incorporation of these innovations at the curricular and practical level for teacher training schools and for in-service teacher development programmes in Mexico and elsewhere. 相似文献

¿Para qué utiliza el lenguaje el niño? ¿Existen funciones del lenguaje más o menos fuertes o más o menos presentes a lo largo de su desarrollo? En el trabajo, que presenta datos empíricos sobre el peso de las distintas funciones del lenguaje desde los 3 a los 10 años, pueden apreciarse cambios evolutivos importantes respecto al protagonismo de estas funciones. 相似文献
