ABSTRACT

The purpose of this article is to explore the development of the knowledge base on middle leadership in schools. Since the seminal reviews conducted by Bennett a contemporary scan only of the scholarly literature on middle leaders/leadership in schools has not been undertaken. Consequently, this article looks at outputs relating to this topic by examining research papers indexed in the Web of Science and in SCOPUS between 2003 and 2017. The prime purpose of this review is to offer some reflections on the development of the empirical base on middle leadership in schools since 2003 and to highlight some of the implications for future research. The article concludes that middle leadership in schools remains an ongoing focus of research inquiry in a growing number of countries but suggests that the knowledge base would benefit from more sophisticated empirical studies and greater theoretical analysis.  相似文献   

Video-stimulated recall in cross-cultural research in education: a case study in Vietnam     

Nga Thanh Nguyen  Donna Tangen 《International Journal of Research & Method in Education》2017,40(5):445-455

This paper examines incorporating video-stimulated recall (VSR) as a data collection technique in cross-cultural research. With VSR, participants are invited to watch video-recordings of particular events that they are involved in; they then recall their thoughts in relation to their observations of their behaviour in relation to the event. The research draws on a larger Ph.D. project completed at an Australian university that explored Vietnamese lecturers’ beliefs about learner autonomy. In cross-cultural research, using the VSR technique provided significant challenges including time constraints of participants, misunderstandings of the VSR protocol and the possibility of participants’ losing face when reflecting on their teaching episodes. Adaptations to the VSR technique were required to meet the cultural challenges specific to this population, indicating a need for flexibility and awareness of the cultural context for research.  相似文献   

Acute phase reactants, challenge in the near future of animal production and veterinary medicine     

Gruys E  Toussaint MJ  Upragarin N  Van EA  Adewuyi AA  Candiani D  Nguyen TK  Sabeckiene J 《Journal of Zhejiang University. Science. B》2005,6(10):941-947

INTRODUCTION The systemic acute phase reaction known to occur on infection, inflammation, trauma, burns, ma- lignancies and tissue damage in general, has been studied by scientists from various disciplines. In the last decade, emphasis has been laid on application of blood tests for acute phase reactants to monitor ani-mal health in general, as well as for human patients suffering from specified classes of diseases (Gruys et al., 2005). However, basic mechanistic patterns as- sociated wit…  相似文献   

Streaming and congestion control using scalable video coding based on H.264/AVC     

NGUYEN Dieu Thanh  OSTERMANN Joern 《浙江大学学报(A卷英文版)》2006,7(5):749-754

INTRODUCTION Streaming of multimedia data over the Internet has rapidly increased in recent years. All commercial applications and most research in video streaming use conventional hybrid video coding. To adapt the data transmission rate on the server to the varying bandwidth caused by congestion in the Internet or to different available bandwidths of different clients, the simulcast solution is widely applied (Balk et al., 2003; Feamster et al., 2001; Schierl and Wiegand, 2004).

Anticipation to Social and Nonsocial Dynamic Cues in Preschool-Age Children     

Jae Engle  Hazel Baker-Harvey  Hieu-Kevin Nguyen  Hunter Carney  Katherine Stavropoulos  Leslie J. Carver 《Child development》2021,92(3):811-820

The ability to learn from expectations is foundational to social and nonsocial learning in children. However, we know little about the brain basis of reward expectation in development. Here, 3- to 4-year-olds (N = 26) were shown a passive associative learning paradigm with dynamic stimuli. Anticipation for reward-related stimuli was measured via the stimulus preceding negativity (SPN). To our knowledge, this is the first study to measure an SPN in children younger than age 6. Our findings reveal distinct anticipatory neural signatures for social versus nonsocial stimuli, consistent with previous research in older children. This study suggests an SPN can be elicited in preschoolers and is larger for social than nonsocial stimuli.  相似文献   

Back to school in Afghanistan: Determinants of school enrollment     

Stephane Guimbert  Keiko Miwa  Duc Thanh Nguyen 《International Journal of Educational Development》2008

One of the first achievements of post-conflict Afghanistan was to bring almost 4 million children back to school. Issues remain daunting, however, with low primary enrollment especially for girls and in rural areas and very weak learning achievements. We review some key features of the education system in Afghanistan. By matching household and school data, we assess the impact of various factors on enrollment. Overall, the analysis indicates that further increasing supply alone is unlikely to lead to higher enrollment. The analysis confirms the importance of demand factors such as the education of parents, the family language, and other community and ethnic factors.  相似文献   

Learning analytics to uncover inequality in behavioural engagement and academic attainment in a distance learning setting     

Quan Nguyen  Bart Rienties  John T. E. Richardson 《Assessment & Evaluation in Higher Education》2020,45(4):594-606

Abstract

Although the attainment gap between black and minority ethnic (BME) students and white students has persisted for decades, the potential causes of these disparities are highly debated. The emergence of learning analytics allows researchers to understand how students engage in learning activities based on their digital traces in a naturalistic setting. This study investigates the attainment gap by analysing the differences in behavioural engagement between different ethnic groups. Using multilevel models of academic performance, demographics, and online traces of 149,672 students enrolled in 401 modules in a distance learning setting, we confirmed the existing attainment gap. After controlling for other demographics, module characteristics and engagement, BME students were between 19% and 79% less likely to complete, pass or achieve an excellent grade compared to white students. Given the same academic performance, BME students spent 4-12% more time on studying than white students. While the attainment gap remained persistent after controlling for academic engagement, our study further highlighted the inequality of attainment between BME and white students.  相似文献

Evaluating the Benefits and Values of Textbooks: Perceptions of Vietnamese Business Students     

The Ninh Nguyen  Viet Thao Tran  Hien Anh Nguyen  Lan Phuong Bui  Phuong Linh Dang 《Publishing Research Quarterly》2018,34(3):378-384

This study aims to examine students’ perceived benefits and values of textbooks, with a specific focus on emerging markets. A paper-based survey was used to collect data from 459 Vietnamese students in three business disciplines including accounting, international business and marketing. The findings reveal that Vietnamese business students view textbooks as having greater short-term benefits than long-term ones. They also believe that textbooks have relatively low economic value. Interestingly, marketing students perceive that textbooks provide primarily benefits of improving class performance, while accounting students tend to view textbooks to have benefits of clearer understanding of relevant concepts. Implications for key stakeholders in the higher education book publishing industry are discussed and future research directions presented.  相似文献   

Causal Mediation Analysis With a Binary Outcome and Multiple Continuous or Ordinal Mediators: Simulations and Application to an Alcohol Intervention     

Trang Quynh Nguyen  Yenny Webb-Vargas  Ina M. Koning  Elizabeth A. Stuart 《Structural equation modeling》2016,23(3):368-383

We investigate a method to estimate the combined effect of multiple continuous/ordinal mediators on a binary outcome: (a) fit a structural equation model with probit link for the outcome and identity/probit link for continuous/ordinal mediators, (b) predict potential outcome probabilities, and (c) compute natural direct and indirect effects. Step 2 involves rescaling the latent continuous variable underlying the outcome to address residual mediator variance and covariance. We evaluate the estimation of risk-difference- and risk-ratio-based effects (RDs, RRs) using the maximum likelihood (ML), mean-and-variance-adjusted weighted least squares (WLSMV) and Bayes estimators in Mplus. Across most variations in path-coefficient and mediator-residual-correlation signs and strengths, and confounding situations investigated, the method performs well with all estimators, but favors ML/WLSMV for RDs with continuous mediators, and Bayes for RRs with ordinal mediators. Bayes outperforms ML/WLSMV regardless of mediator type when estimating RRs with small potential outcome probabilities and in two other special cases. An adolescent alcohol prevention study is used for illustration.  相似文献
