European universities are facing demands for better student retention, especially in countries where state funding is no longer based on the number of students, but on the number of graduates. An extensive literature on retention focuses on the characteristics of students who leave higher education without a degree. Much less is known about the measures taken by higher education institutions to encourage study progress. This article examines whether retention strategies are incorporated into the institutions’ overall strategies and the policies and activities developed by universities to foster study progress and enhance retention rates. The results suggest that the universities’ overall strategies and retention activities are loosely coupled and that the universities tend to use blanket measures addressing retention, regardless of why students are leaving.  相似文献

Utilizing forest gardens as urban settings for outdoor environmental education in Sweden is a new practice. These forest gardens combine qualities of a forest, e.g., multi-layered polyculture vegetation, with those of a school garden, such as accessibility and food production. The study explores both the perceived qualities of forest gardens in comparison to other outdoor settings and forest garden educators' ideas, purposes, and experiences of activities in a three-year forest gardening project with primary school children. The data were collected through interviews and observations and analyzed qualitatively. Four reported ideas were to give children opportunities to: feel a sense of belonging to a whole; experience self-regulation and systemic dependence; experience that they can co-create with non-human organisms; and imagine possible transformation of places. Four pedagogical forest garden features are discussed.  相似文献

Previous studies have documented robust relationships between emergent literacy and later reading performance. A growing body of research has also reported associations between motivational factors and reading in early phases of reading development. However, there is less research about cross-lagged relationships between motivational factors and reading skills in beginning readers. To examine relationships between early reading skills, literacy interest and reader self-concept, we tested 1141 children twice during their first year of formal reading instruction in school. Cross-lagged analysis showed strong stability in reading skills and medium stability in literacy interest and reader self-concept over the first school year. We also found bidirectional relationships between reading skills and self-concept and between the motivational components of literacy interest and reader self-concept. In the final part of the article, we address the potential theoretical progress attainable through the use of cross-lagged designs in this field.  相似文献

Situation awareness (SA) refers to the awareness of all relevant sources of information, an ability to synthesise this information using domain knowledge gained from past experiences and the ability to physically respond to a situation. Expert-novice differences have been widely reported in decision-making in complex situations although determining the small differences in expert behaviour are more elusive. This study considered how expert squash players use SA to decide on what shot to play. Matches at the 2010 (n = 14) and 2011 (n = 27) Rowe British Grand Prix were recorded and processed using Tracker software. Shot type, ball location, players’ positions on court and movement parameters between the time an opponent played a shot prior to the player’s shot to the time of the opponent’s following shot were captured 25 times per second. Six SA clusters were named to relate to the outcome of a shot ranging from a defensive shot played under pressure to create time to an attempted winner played under no pressure with the opponent out of position. This new methodology found fine-grained SA differences in expert behaviour, even for the same shot type played from the same court area, beyond the usual expert-novice differences.  相似文献

This paper treats document–document similarity approaches in the context of science mapping. Five approaches, involving nine methods, are compared experimentally. We compare text-based approaches, the citation-based bibliographic coupling approach, and approaches that combine text-based approaches and bibliographic coupling. Forty-three articles, published in the journal Information Retrieval, are used as test documents. We investigate how well the approaches agree with a ground truth subject classification of the test documents, when the complete linkage method is used, and under two types of similarities, first-order and second-order. The results show that it is possible to achieve a very good approximation of the classification by means of automatic grouping of articles. One text-only method and one combination method, under second-order similarities in both cases, give rise to cluster solutions that to a large extent agree with the classification.  相似文献

The purpose was to study the adaptation to speed in the temporal patterns of the movement cycle and determine any differences in velocity, cycle rate and cycle length at the maximum speed level in the different classical style and freestyle cross-country skiing techniques. Eight skilled male cross-country skiers were filmed with a digital video camera in the sagittal plane while skiing on a flat cross-country ski track. The skiers performed three classical style techniques the diagonal stride, kick double poling and the double poling technique and four freestyle techniques paddle dance (gear 2), double dance (gear 3), single dance (gear 4) and combiskate (gear 5) at four different self-selected speed levels slow, medium, fast and their maximum. Cycle duration, cycle rate, cycle length, and relative and absolute cycle phase duration of the different techniques at the different speed levels were analysed by means of a video analysis system. The cycle rate in all tested classical and freestyle techniques was found to increase significantly (p < .01) with speed from slow to maximum. Simultaneously, there was a significant decrease in the absolute phase durations of all the investigated skiing techniques. A minor, not significant, change in cycle length, and the significant increase in cycle rate with speed showed that the classical and freestyle cross-country skiing styles are dependent, to a large extent, on an increase in cycle rate for speed adaptation. A striking finding was the constant relative phase duration with speed, which indicates a simplified neural control of the speed adaptation in both cross-country skiing styles. For the practitioner, the knowledge about the importance of increasing cycle frequency rather than cycle length in the speed adaptation can be used to optimise a rapid increase in speed. The knowledge about the decrease in absolute phase duration, especially the thrust phase duration, points to the need for strength and technique training to enable force production at a high cycle rate and skiing speed. The knowledge that the relative phase duration stays constant with speed may be used to simplify the learning of the different cross-country skiing techniques.  相似文献

In 2005–2006 the research group DRACE (Digital Radio Cultures in Europe) performed a study on how 43 people in key positions related to the radio industry in 4 European countries and Canada viewed the future of radio and which delivery technologies they considered would be most successful. In addition, it analyzed the motives and reasons certain technologies were seen as more promising than others. Finally, it presented 4 different future scenarios for radio media. The study was published in the Journal of Radio and Audio Media, May 2008.

In 2005 the future of radio was considered much less obvious and clear than it appeared 10 years previously. Instead of a transition from analog to digital audio broad- casting (DAB), there was a selection of alternative technological options for digital audio delivery. When looking back from 2015 and considering the results of expert interviews, the project group about Public Service Media in the HERA project: Transnational Radio Encounters found interesting perspectives in replicating this study—now looking forward to 2025. By using the same questionnaire and interviewing the same experts (or new persons in the same positions) they could compare the predictions with the present situation, looking for technological, regulatory, policy based, and user-oriented contexts. Furthermore, they could ask the experts to look 10 years forward to 2025. Besides from the interviews, desk studies were performed in order to explore the national similarities and differences as background for the analysis of the scenarios for the 2015 and 2025 studies.

This comparative study involves Denmark, Finland, Germany, Ireland, and the UK.  相似文献

ABSTRACT

Medication review, a systematic assessment of a patient’s medicines by a health care professional, is intended to prevent medication-related harms. A critical element of medication review concerns whether medication review is conducted in a coordinated way. This article draws from a case example of implementing medication review in two surgical wards of a Swedish regional hospital and aims to analyse how medication review is being accomplished with respect to the coordination of its actions. Using a practice-based ethnographic approach, we present several coordination mechanisms by illustrating how practices are connected to materials involved in medication review. Also, we show how common orientations, ends, and understandings expressed in different medication review practices contribute to the coordination of the practices. In conclusion, this article highlights the complexity of establishing and sustaining medication review as a coordinated practice in routine health care. By closely examining sociomaterial connections, this article sheds new light on the neglected issue of artefacts and arrangements in constituting and transforming a highly complex medication practice.  相似文献

ABSTRACT— Our understanding of the causes of a developmental disorder like dyslexia has received recent input from both neuroscience and genetics. The discovery of 4 candidate genes for dyslexia and the identification of neuronal networks engaged when children read and spell are the basis for introducing this knowledge into education. However, the input from educational practitioners as well as empirical knowledge from research on learning also contribute significantly to our understanding of how children acquire the basic skills for learning to read and spell. It is imperative to merge the knowledge acquired from research in the fields of neuroscience, genetics, and empirical education, as well as to understand how the learning brain and instruction interact. Doing so can be seen as a major step in attaining an optimal approach for teaching, reading, and spelling and for finding the best suited and most effective treatment concepts for dyslexic children and adolescents.  相似文献
