International University Education: An Australian Perspective   总被引:1,自引:1,他引:0  
This paper attempts to explore the effectiveness of UK universities' websites. The area of branding in higher education has received increasing academic investigation, but little work has researched how universities demonstrate their brand promises through their websites. The quest to differentiate through branding can be challenging in the university context, however. It is argued that those institutions that have a strong distinctive image will be in a better position to face a changing future. Employing a multistage methodology, the web pages of 20 UK universities were investigated by using a combination of content and multivariable analysis. Results indicated ‘traditional values’ such as teaching and research were often well communicated in terms of online brand but ‘emotional values’ like social responsibility and the universities' environments were less consistently communicated, despite their increased topicality. It is therefore suggested that emotional values may offer a basis for possible future online differentiation.  相似文献

Despite the belief that schools tend to be resistant to change, it is possible to find secondary schools in the UK which are investing in the design of an innovative curriculum for their Year 7 (11-year-old students). This article focuses on four of these schools and discusses some of the challenges they face in planning and implementing their competence-based curricula (CBC). Such curricula tend to be based on the rationale that they better prepare all students for the constant changes of human knowledge and understanding. They develop transferable skills rather than subject-specific content, which are considered necessary requirements for learners as future productive members of society in the twenty-first century. Advocates of CBC argue that such curricula are more inclusive and emancipatory than traditional curricula, although this view is contested. Employing Bernstein's concepts of framing and classification of the curriculum, this article describes the challenges and constraints encountered by four schools which have endeavoured to develop a competence-based curriculum.  相似文献

Resumen

El presente informe analiza la expresión emocional de los ciegos congénitos mediante una codificación muscular de los movimientos faciales. Esta expresión, de carácter más involuntario, es semejante a la de los videntes. En cambio, los sujetos invidentes tienen una expresividad menor y menos diferenciada en las poses voluntarias. Los resultados, que confirman los hallazgos de autores anteriores, apoyan la existencia de dos fuentes de información en el desarrollo emocional: una de naturaleza genética, que explicaría las semejanzas en la expresión emocional o involuntaria, y otra ambiental, que daría cuenta de las diferencias en la expresión voluntaria. Por último, se plantean las consecuencias de este trabajo para las distintas disciplinas psicológicas.  相似文献

Resumen

Mediante tareas de clasificación de segmentos-palabra, se investiga la evolución infantil en la reflexión sobre el propio idioma (capacidad gramatical). Los datos demuestran que esta evolución pasa por largos períodos—entre ocho y once años—de estrategias semántico-pragmáticas y, por tanto, inmaduras gramaticalmente.  相似文献

Resumen

El propósito de este estudio fue diseñar un modelo válido para la adquisición de unos adecuados hábitos de estudio, basado en una combinación de estrategias de autorregulación y técnicas de estudio. Se procedió mediante un diseño exploratorio de línea de base múltiple, con un único sujeto que incluía: a) fase de pretest, b) primera fase de intervención, en la que se introdujeron las estrategias de autorregulación, c) segunda fase de intervención o de introducción de las técnicas de estudio, y d) fase de postest. El resultado fue un cambio experimental y terapéuticamente significativo en los hábitos de estudio y en las conductas exponentes de: tiempo de estudio, desatención, y velocidad y comprensión lectoras, las calificaciones experimentaron un ascenso progresivo. Estos cambios se mantuvieron y consolidaron en el seguimiento, las estrategias de autorregulación se han mostrado útiles para aumentar la probabilidad de ocurrencia de la conducta deseada y disminuir la de la no deseada.  相似文献

The main purpose of this study is to analyze whether quality of preschool classrooms relates to 4- and 5-year-old children developmental outcomes. The study was conducted in 60 classrooms in Porto Metropolitan Area, Portugal. Children (N?=?215) were evaluated in the literacy, math, and behavior domains. Preschool quality was assessed through classroom observations using the ECERS-R and the Early Language and Literacy Classroom Observation. Global classroom quality although relatively low, predicted children’s literacy skills and behavior but not math skills. Quality of language and literacy environment was not consistently related to child outcomes. Mother educational level stood out as consistently predicting most of child developmental outcomes. The relevance of these results is discussed considering the Portuguese educational scenario, in the realm of an international context.  相似文献

This paper reports a classroom-based study involving investigation activities in a university numerical analysis course. The study aims to analyse students' mathematical processes and to understand how these activities provide opportunities for problem posing. The investigations were intended to stimulate students in asking questions, to trigger their thinking processes, to promote their ability to investigate and to support them in learning numerical analysis' concepts and procedures. The results show that the investigations provided opportunities for students to experience mathematical processes, including posing questions, formulating and testing conjectures and, to some extent, proving results. They also provide some understanding about the role of problem posing in these processes. Posing questions occurred mainly in an implicit way, in the interpretation of tasks and in identifying regularities, analysing graphs and testing cases. The conjectures were often based on pattern identification or data manipulation, and the students tended to accept them without testing or proving. The students also proposed alternative formulations for the initial questions and posed new problems from their explorations and attempts to refine previous conjectures.  相似文献

Using genetic algorithms to evolve a population of topical queries   总被引:1,自引:1,他引:0  
Systems for searching the Web based on thematic contexts can be built on top of a conventional search engine and benefit from the huge amount of content as well as from the functionality available through the search engine interface. The quality of the material collected by such systems is highly dependant on the vocabulary used to generate the search queries. In this scenario, selecting good query terms can be seen as an optimization problem where the objective function to be optimized is based on the effectiveness of a query to retrieve relevant material. Some characteristics of this optimization problem are: (1) the high-dimensionality of the search space, where candidate solutions are queries and each term corresponds to a different dimension, (2) the existence of acceptable suboptimal solutions, (3) the possibility of finding multiple solutions, and in many cases (4) the quest for novelty. This article describes optimization techniques based on Genetic Algorithms to evolve “good query terms” in the context of a given topic. The proposed techniques place emphasis on searching for novel material that is related to the search context. We discuss the use of a mutation pool to allow the generation of queries with new terms, study the effect of different mutation rates on the exploration of query-space, and discuss the use of a especially developed fitness function that favors the construction of queries containing novel but related terms.  相似文献

High Intensity Interval Training (HIIT) can be performed with different effort to rest time-configurations, and this can largely influence training responses. The purpose of the study was to compare the acute physiological responses of two HIIT and one moderate intensity continuous training (MICT) protocol in young men. A randomised cross-over study with 10 men [age, 28.3?±?5.5years; weight, 77.3?±?9.3?kg; height, 1.8?±?0.1?m; peak oxygen consumption (VO2peak), 44?±?11?mL.kg?1.min?1]. Participants performed a cardiorespiratory test on a treadmill to assess VO2peak, velocity associated with VO2peak (vVO2peak), peak heart rate (HRpeak) and perceived exertion (RPE). Then participants performed three protocols equated by distance: Short HIIT (29 bouts of 30s at vVO2peak, interspersed by 30s of passive recovery, 29?min in total), Long HIIT (3 bouts of 4?min at 90% of vVO2peak, interspersed by 3?min of recovery at 60% of vVO2peak, 21?min in total) and MICT (21?min at 70% of vVO2peak). The protocols were performed in a randomised order with ≥48 h between them. VO2, HRpeak and RPE were compared. VO2peak in Long HIIT was significantly higher than Short HIIT and MICT (43?±?11 vs 32?±?8 and 37?±?8?mL.kg?1.min?1, respectively, P?P?P?2, HR and RPE than Short HIIT and MICT, suggesting a higher demand on the cardiorespiratory system. Short HIIT and MICT presented similar physiologic and perceptual responses, despite Short HIIT being performed at higher velocities.  相似文献

β-hydroxy-β-methylbutyrate (calcium: HMB-Ca and free acid: HMB-FA) and α-hydroxyisocaproic acid (α-HICA) are leucine metabolites that have been proposed to improve body composition and strength when combined with resistance exercise training (RET). In this double-blind randomized controlled pragmatic trial, we evaluated the effects of off-the-shelf supplements: α-HICA, HMB-FA and HMB-Ca, on RET-induced changes in body composition and performance. Forty men were blocked randomized to receive α-HICA (n?=?10, fat-free mass [FFM]?=?62.0?±?7.1?kg), HMB-FA (n?=?11, FFM?=?62.7?±?10.5?kg), HMB-Ca (n?=?9, FFM?=?65.6?±?10.1?kg) or placebo (PLA; n?=?10, FFM?=?64.2?±?5.7?kg). The training protocol consisted of a whole-body resistance training routine, thrice weekly for 8 weeks. Body composition was assessed by dual-energy x-ray absorptiometry (DXA) and total body water (TBW) by whole-body bioimpedance spectroscopy (BIS), both at baseline and at the end of weeks 4 and 8. Time-dependent changes were observed for increase in trunk FFM (p?相似文献
