Effect of Tai Chi exercise on blood lipid profiles: a meta-analysis of randomized controlled trials

Objective

Studies have demonstrated that Tai Chi exercise improves blood lipid level with inconsistent results. A meta-analysis was conducted to quantify the effects of Tai Chi on blood lipid profiles in humans.

Methods

We screened the databases of PubMed, EMBASE, Cochrane Library (Central), Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang data, and Clinicaltrials.gov for randomized controlled trials with Physiotherapy Evidence Database (PEDro) score more than 3 points up to June 2015. Six studies involving 445 subjects were included. Most trials applied 12-week Tai Chi intervention courses.

Results

In comparison with the control group, blood triglyceride (TG) level difference between follow-up and baseline was statistically significantly lower in the Tai Chi practicing group (weighted mean difference (WMD) ?16.81 mg/dl; 95% confidence intervals (CI) ?31.27 to ?2.35 mg/dl; P=0.02). A trend to improving total cholesterol (TC) reduction was found with Tai Chi (WMD ?7.96 mg/dl; 95% CI ?17.30 to 1.39 mg/dl; P=0.10). However, no difference was found in blood low-density lipoprotein cholesterol (LDL-C) or high-density lipoprotein cholesterol (HDL-C).

Conclusions

Tai Chi exercise lowered blood TG level with a trend to decrease blood TC level. Our data suggest that Tai Chi has the potential to implement meaningful blood lipid modification and serve as an adjunctive exercise modality. The relationship between Tai Chi exercise regimen and lipid profile change might have a scientific priority for future investigation.

     

Teachers enacting a technology-rich curriculum for emergent literacy

PictoPal is the name of a technology-rich curriculum with a focus on emergent literacy of Dutch kindergarteners. A case study design was used to examine teacher technology integration within PictoPal along with their perceptions about teaching/learning, technology and technology-based innovations. Observations were undertaken on pupils’ engagement and teachers’ technology integration within PictoPal. Interviews were used to examine teachers’ perceptions. Pupils’ emergent literacy learning was examined in a nonequivalent control quasi experimental design. Four kindergarten teachers and four classes (N = 95 pupils) participated in the use of PictoPal. The findings suggest that a high extent of technology integration is related to: a developmental approach to teaching/learning; positive attitudes and expectations towards technology-based innovations; and positive perceptions of support in stressful work conditions. Significant learning gains were found for the experimental group using PictoPal. High pupil learning gains were not related to a high extent of technology integration. Senior kindergarteners engaged to a higher extent with PictoPal than junior kindergarteners.     

New approaches to facilitate learning from youth: Exploring the use of Photovoice in identifying local watershed issues

In urbanized areas, incorporating residents’ concerns and priorities into the stormwater management debate has focused on adults rather than youth. This study used Photovoice, a tool that includes photographs taken by youth, to uncover youth concerns and perceptions about their local watersheds. This study consisted of a comparative study of two watersheds. Twenty students produced 468 photographs. Although both groups of students shared common themes regarding stormwater and pollution, these themes differed in level of concerns over local environmental issues, sentiments with particular features in their local watersheds, and concerns about local watersheds. From a methodological perspective, Photovoice provided a way of capturing youth perspectives and to identify important features and issues in their respective local watersheds.     

Behaviour intervention for a student with Tourette's Syndrome: a case study

In an increasingly inclusive and complex setting, professionals in the school workforce working with children presenting social, emotional and behavioural difficulties are managing difficulties that frequently reflect co‐morbidity and multiple‐disorder. This article reports practitioner‐led research taking place in a mainstream school in the USA exploring the behaviour management of a pupil presenting with Tourette's Syndrome (TS). The research takes the form of a case study of a teacher‐led intervention. The research introduced the use of functional behavioural assessment (FBA) and a peer support group as the basis of the intervention. This method was aimed at involving teachers more specifically and broadening practitioners' perspectives on the ‘reasons’ and ‘antecedents’ for behaviours being presented. An outcome of the research was the blended use of an FBA and a peer support group process to increase the interaction skills of a student with TS and supported inclusive education for the student.     

Teachers as co-designers of technology-rich learning activities for early literacy

Although kindergarten teachers often struggle with implementing technology, they are rarely involved in co-designing technology-rich learning activities. This study involved teachers in the co-design of technology-rich learning activities and sought to explore implementation and pupil learning outcomes. A case-study method was used to investigate: the co-design experiences of seven teachers; implementation in three kindergarten classes; and pupil learning outcomes. Interviews were used to study teacher perceptions about pedagogy, technology, early literacy, co-designer role, practicality and co-ownership. Process notes were made during design team meetings. Observations were made of implementation, and pupil learning was pre- and post-tested in non-equivalent control quasi-experimental design (N = 111). Findings indicate that teacher perceptions about pedagogy affect their co-design involvement. The extent of integration of on- and off-computer activities was similar between teachers. Significant pupil learning gains were found, thus indicating that the co-designed activities had positive effects on pupil learning outcomes.

The ‘critical friend’ role in fostering reflective practices and developing staff cohesion: A case study in a new secondary school,New Zealand

This exploratory case study, arising from a longitudinal project into the establishment of a new secondary school in New Zealand, examines reflective practice through critical friend roles among staff. The paper describes, through the lens of Bourdieu's logic of practice, the implementation of a critical friendship approach linked to the school leaders’ vision and aim regarding learning within open classroom spaces as part of a modern learning environment. Reflective practice involves critiquing, rethinking and reframing existing professional practices, often through a critical friendship approach among school staff within a fostered collaborative and open culture. The researchers interviewed six participants (four leaders and two teachers), observed how the teaching and learning took place in the new open classroom spaces, and reviewed blog posts and the school's website. Findings reveal that critical friendship, as a way to develop staff cohesion, is fostered and supported by the school leaders’ vision and actions, while the physical geography of the new classroom spaces, and the redesign of learning, also make this easier to enact. Staff cohesion, trust and openness to peer scrutiny are hallmark of this emerging school culture. These emerging findings provide some insights into how one new school culture develops cohesion with its stated vision and mission.     

Hybrid query expansion model for text and microblog information retrieval

Query expansion (QE) is an important process in information retrieval applications that improves the user query and helps in retrieving relevant results. In this paper, we introduce a hybrid query expansion model (HQE) that investigates how external resources can be combined to association rules mining and used to enhance expansion terms generation and selection. The HQE model can be processed in different configurations, starting from methods based on association rules and combining it with external knowledge. The HQE model handles the two main phases of a QE process, namely: the candidate terms generation phase and the selection phase. We propose for the first phase, statistical, semantic and conceptual methods to generate new related terms for a given query. For the second phase, we introduce a similarity measure, ESAC, based on the Explicit Semantic Analysis that computes the relatedness between a query and the set of candidate terms. The performance of the proposed HQE model is evaluated within two experimental validations. The first one addresses the tweet search task proposed by TREC Microblog Track 2011 and an ad-hoc IR task related to the hard topics of the TREC Robust 2004. The second experimental validation concerns the tweet contextualization task organized by INEX 2014. Global results highlighted the effectiveness of our HQE model and of association rules mining for QE combined with external resources.     

Education in and for the Belt and Road Initiative:

Abstract

This paper is an experiment in collective writing conducted in Autumn 2019 at the Faculty of Education at Beijing Normal University. The experiment involves 12 international masters' students reading the course based on the Belt and Road Initiative (BRI), their professor Michael Peters, visiting professor Petar Jandri?, and a mix of senior Chinese and Western scholars. To successfully complete the course, the students were required to produce a 3000-word paper of publishable quality. As part of this writing process we decided to engage in the experiment of collective writing where we aimed to produce a single paper consisting of the abstracts. This collective paper was developed in 7 steps. (1) Students submitted their 250-word abstracts. (2) Students were introduced into the methodology of collective writing, and 2 student-editors – Ogunniran Moses Oladele and Benjamin Green – volunteered to work on the paper. (3) Michael Peters wrote the introduction. (4) Abstracts were expanded to 500 words and integrated into a single document. (5) Petar Jandri? began to edit the paper and write a conclusion. (6) Students presented their abstracts in the class, where Michael Peters and Petar Jandri? provided direct feedback. (6) Revised abstracts were again integrated into a single document by student editors, and proofread / copy-edited in several exchanges with the instructors (7) The paper was subject to the process of open review, and the reviewer's comments were included in the paper. Resulting from months of collective work, the final paper provides a wide range of views ad perspectives to the question of education as a part of the BRI initiative.
