This study employs digital methods in conjunction with traditional content and discourse analyses to explore how the US President Donald Trump conducts diplomacy on Twitter and how, if at all, diplomatic entities around the world engage in diplomatic exchanges with him. The results confirm speculations that Trump’s diplomatic communication on Twitter disrupts traditional codes of diplomatic language but show little evidence that new codes of diplomatic interactions on social media are being constructed, given that other diplomatic entities around the world mostly remain within the confines of traditional notions of diplomacy in (not) communicating with Trump on Twitter. 相似文献

Abstract There is a risk of hip injury in dives to the side by soccer goalkeepers. In this study, we assessed hip loading in goalkeepers when performing such dives. The experiments were conducted in a laboratory setting using an in-ground force plate as well as on a grass surface when the athletes were equipped with force sensors. The forces acting on the hip were measured and high-speed video analysis was performed, allowing the investigation of the dive characteristics and techniques. The peak force values recorded in the laboratory setting ranged from 3 to 8 kN, which corresponded to 4.2–8.6 times body weight. The vertical impact velocities reached 3.25 m · s?1. In the field experiments, a hip loading of 87–183 N · cm?2 was determined. We found that goalkeepers who perform a rolling motion reduce their hip loading. The data provided by this study add to the biomechanics database and contribute to the establishment of injury criteria. Such information is necessary to develop and implement strategies to help prevent hip injuries. 相似文献

In this paper we propose improved variants of the sentence retrieval method TF–ISF (a TF–IDF or Term Frequency–Inverse Document Frequency variant for sentence retrieval). The improvement is achieved by using context consisting of neighboring sentences and at the same time promoting the retrieval of longer sentences. We thoroughly compare new modified TF–ISF methods to the TF–ISF baseline, to an earlier attempt to include context into TF–ISF named tfmix and to a language modeling based method that uses context and promoting retrieval of long sentences named 3MMPDS. Experimental results show that the TF–ISF method can be improved using local context. Results also show that the TF–ISF method can be improved by promoting the retrieval of longer sentences. Finally we show that the best results are achieved when combining both modifications. All new methods (TF–ISF variants) also show statistically significant better results than the other tested methods. 相似文献

Globalisation is often referred to as being external to education – a state of affairs presenting the modern curriculum with numerous challenges. In this article, ‘globalisation’ is examined as something that is internal to curriculum and analysed as a problematisation in a Foucaultian sense, that is, as a complex of attentions, worries and ways of reasoning, producing curricular variables. The analysis is made through an example of early childhood curriculum in Danish preschool, and the way the curricular variable of the preschool child comes into being through ‘globalisation’ as a problematisation, carried forth by comparative practices such as Programme for International Student Assessment. It thus explores some of the systems of reason that educational comparative practices carry through time, focusing on the ways in which configurations are reproduced and transformed, forming the preschool child as a site of economic optimisation. 相似文献

FRBR, FRAD, and FRSAD models propose user tasks as a way to address and categorize functions that a catalog should support. The user tasks are not harmonized among these models, but to do that, they should first be fully understood and analyzed, especially “select” and “identify.” We decided to look at the FRBR user tasks from the perspective of interactive information retrieval (IIR). Several IIR models were reviewed and Ellis’ and Belkin's models were chosen for further analysis and interpretation of FRBR “select” and “identify” tasks. 相似文献

Through an analysis of a recent Danish administrative educational reform in the area of early childhood education, this article raises a discussion about the way pedagogical objects and subjects are generated in the knowledge acquisition of administrative educational reforms promoting accountability, visibility and documentation. It is argued that pedagogy is generated as a sequential and unit-specified way of working on the production of ‘the learning child’, forming a time- and material-optimising approach. Hereby, the nursery teacher, as a daily scientific researcher, comes to serve the nation by an ongoing observational intervention, producing the learning foundation for the entrepreneurial citizen, and thus the nation as a knowledge society in a globalised world. This is what this article terms the emergence of the analytical method. 相似文献

The study examined the predictive value of adolescents’ personality trait ratings by different groups of informants in explaining academic achievement [grade point average (GPA)] while controlling for students’ sex and their mothers’ education. The Inventory of Child/Adolescent Individual Differences was employed as a measure of students’ personality traits at the end of elementary schooling (mean age = 14.7 years) and two years later when the participants attended secondary schools. The trait ratings were obtained through self‐, maternal and peer reports at both measurement occasions. They explained substantial portions of unique variance in the students’ GPA concurrently, and over time. Ratings by each of the three groups of informants had an incremental validity over one another in predicting school grades. Among personality variables, conscientiousness and low extraversion were consistently predictive of GPA. 相似文献

This article reflects on and discusses Central and Eastern European (CEE) learners’ adaptability and achievement in one English post-1992 university. There appears to be a scarcity of studies of values, beliefs, attitudes and needs as well as achievement (and factors contributing to it) between CEE and other learners. Since the expansion of the European Union, CEE students’ presence in British higher education has become more pronounced. CEE learners are treated as home students (for the purpose of fees) and yet they come from a distinctively different socio-historical background and pedagogic tradition – tradition (as explained further in the article) that is, to a certain extent, common in CEE countries as a result of the sovietisation of education systems within post communistic countries of Central and Eastern Europe. In the British higher education sector there is a move in curriculum delivery towards more personalised learning, which underlines that effective teaching and learning starts with understanding the individual student. Therefore, it is important that universities with a high proportion of EU students attempt to understand where CEE students come from and what their aspirations might be. This article provides some insights into CEE learners’ values, attitudes and motivations to learn and looks for possible reasons for their success. 相似文献
