Purpose:To investigate whether blood flow restriction(BFR) without concomitant exercise mitigated strength reduction and atrophy of thigh muscles in subjects under immobilization for lower limbs.Methods:The following databases were searched:PubMed,CINAHL,PEDro,Web of Science,Central,and Scopus.Results:The search identified 3 eligible studies,and the total sample in the identified studies consisted of 38 participants.Isokinetic and isometric torque of the knee flexors and extensors was examined in 2 studies.Cross-sectional area of thigh muscles was evaluated in 1 study,and thigh girth was measured in 2 studies.The BFR protocol was 5 sets of 5 min of occlusion and 3 min of free flow,twice daily for approximately 2 weeks.As a whole,the included studies indicate that BFR without exercise is able to minimize strength reduction and muscular atrophy after immobilization.It is crucial to emphasize,however,that the included studies showed a high risk of bias,especially regarding allocation concealment,blinding of outcome assessment,intention-to-treat analyses,and group similarity at baseline.Conclusion:Although potentially useful,the high risk of bias presented by original stodies limits the indication of BFR without concomitant exercise as an effective countermeasure against strength reduction and atrophy mediated by immobilization.  相似文献   

Effects of Multimedia versus Live Professional Development on Teachers’ and Students’ Performance Related to the Question Exploration Routine     

Jean B. Schumaker  Joseph B. Fisher  Lisa D. Walsh  Paula E. Lancaster 《Learning disabilities research & practice》2020,35(4):180-200

In each of two studies, teachers were randomly assigned to either a Virtual Workshop (VW) group that used a computerized professional development program or an Actual Workshop (AW) group that participated in face-to-face professional development, including discussion, feedback, and collaboration. In both studies, teachers’ posttest scores related to their knowledge of the Question Exploration Routine and their plans for using it were significantly higher than their pretest scores. In Study 2, both groups’ posttest scores with regard to implementation and planning of the routine were significantly greater than their pretest scores. There were no significant differences between the groups at posttesting on any measure. The posttest knowledge scores of the whole groups of students and the subgroups of students with LD being taught by both groups of teachers were significantly higher than their pretest scores. All teachers indicated that they were satisfied with the training and the routine. VW teachers in both studies indicated that they were satisfied with the software program.  相似文献   

Decolonizing love: ambivalent love in contemporary (anti)sexual movements of Taiwan and South Korea*     

Pei Jean Chen 《Inter-Asia Cultural Studies》2018,19(4):551-567

ABSTRACT

This article problematizes the modern construction of “love” in colonial and contemporary Taiwan and South Korea through historicizing the concept from the nineteenth century to the present. The conception of modern love in East Asia emerged during the late nineteenth century that coincided with the beginnings of civilization and nation-building discourses advocating as a strong mediator for the reconfiguration of social and intimate relationships. In the case of colonial Taiwan and Korea, the colonial governments and intellectuals constantly pivoted on “exceptions” – obscene sex, indecent behavior or illegitimate subjects – to justify their political legitimacy/hegemony to love that prescribed a normative social relationship. Fully embraced by colonial Taiwan and Korea, this mechanism was extended to their postwar regimes; that is, love is celebrated and worshiped without the recognition of its underlying ideology of discrimination and exclusion. I coin the term “love unconscious” to characterize the colonial legacies of love in the contemporary social movements in Taiwan and South Korea. Furthermore I examine how both religious groups and LGBTQ activism were stuck in the “love unconscious” with two cases of contested love: the definition of love in the dictionary, and the rhetoric of love in (anti-)same-sex marriage movements. This article argues that Taiwan and South Korea's LGBTQ and marriage movements are based neither on Western discourses nor inspiration, but are instead driven by the reality and legacy of colonial history. To envisage the decolonization of love is to deconstruct the love unconscious and reconsider the history of colonial love.  相似文献

Bond graphs for thermal energy transport and entropy flow     

Jean U. Thoma 《Journal of The Franklin Institute》1971

The transport of thermal energy in thermodynamics is described as the product of entropy flow and of the absolute temperature, in analogy to the volume flow and pressure in oil hydraulics and to electric charge flow (= current) and voltage in electronics. Bond graphs are shown to be especially suitable to describe the splitting of applied thermal energy into internal energy and external mechanical work. Transformers and the 0- and 1-junctions of Paynter can illustrate various entropy flow processes, including Carnot engines and heat exchangers. Entropy flow in heat conduction is distinguished from entropy convection, or transport by moving mass, where the entropy/temperature characteristic or equation of state is important. Irreversibilities are represented by impedance transformers reducing temperature and increasing entropy flow but conserving power.  相似文献   

Unique-order interpolative coding for fast querying and space-efficient indexing in information retrieval systems     

Cher-Sheng Cheng  Jean Jyh-Jiun Shann  Chung-Ping Chung 《Information processing & management》2006

This paper presents a size reduction method for the inverted file, the most suitable indexing structure for an information retrieval system (IRS). We notice that in an inverted file the document identifiers for a given word are usually clustered. While this clustering property can be used in reducing the size of the inverted file, good compression as well as fast decompression must both be available. In this paper, we present a method that can facilitate coding and decoding processes for interpolative coding using recursion elimination and loop unwinding. We call this method the unique-order interpolative coding. It can calculate the lower and upper bounds of every document identifier for a binary code without using a recursive process, hence the decompression time can be greatly reduced. Moreover, it also can exploit document identifier clustering to compress the inverted file efficiently. Compared with the other well-known compression methods, our method provides fast decoding speed and excellent compression. This method can also be used to support a self-indexing strategy. Therefore our research work in this paper provides a feasible way to build a fast and space-economical IRS.  相似文献   

Empirical evidence of the impact of lesson study on students’ achievement,teachers’ professional learning and on institutional and system evolution     

Peter Dudley  Haiyan Xu  Jan D. Vermunt  Jean Lang 《European Journal of Education》2019,54(2):202-217

In this article we review the evidence of the impact of lesson study on student learning, teacher development, teaching materials, curriculum, professional learning and system enhancement. We argue for lesson study to be treated holistically as a vehicle for development and improvement at classroom, school and system levels rather than as a curricular or pedagogical intervention. We illustrate the need for this approach to evaluating lesson study through a complex case exemplar which used Research Lesson Study (a form of lesson study popular in the UK and Europe) to develop learning, teaching, curriculum and local improvement capacity across schools initially involved in a two‐year mathematics curriculum development project that later evolved into three self‐sustaining, voluntary lesson study school hubs in London. We discuss resulting changes in culture, practice, belief, expectation and student learning. We argue as a result for greater policy level understanding of this expanded conception of lesson study as a vehicle in classroom, school and system transformation.  相似文献   

Is one proof enough? Travels with a mathematician of the baroque period     

Jean Dhombres 《Educational Studies in Mathematics》1993,24(4):401-419

It is reasonable to assume that a subject of presumably universal appeal must rely on just one style. In spite of its universality, mathematics employs many styles. In particular, there are many styles of proof. In this paper we present and analyse a number of proofs of a property of the area under an hyperbola due to Gregory of Saint-Vincent, a mathematician of the first half of the seventeenth century. There is a baroque and prolific quality to the architecture of his proofs, and this quality points to a connection between a culture and the discovery of a mathematical theory. An historical perspective shows that, in addition to many styles, the universality of mathematics implies a variety of procedures.This work was carried out during a period as guest professor at the Institut de physique théorique, Université de Louvain.  相似文献   

Predicting Parent-Child Differences in Perceptions of How Children Use the Internet for Help With Homework,Identity Development,and Health Information     

Sherri Jean Katz  Theodore Lee  Sahara Byrne 《广播与电子媒介杂志》2015,59(4):574-602

Bioecological systems theory provides a framework to understand how factors in the child's environment contribute to parent-child differences in estimations of how often children are helped by their Internet use. A national sample survey of 456 matched parent-child pairs investigated how parents-child relational factors, parental attitudes toward the Internet, and the bio-ecology of the child, are related to differing perceptions of the frequency of using the Internet to seek help with homework assignments, to aid in identity development, and to find health information. While previous research shows that parents underestimate risky online behaviors, we investigate whether parent-child differences will emerge in regards to how often the child engages in the behaviors under investigation here. The findings show that parents overestimate these online activities, suggesting they are biased in their estimations. Parent-child relational factors emerged as predictors of parental overestimation for each of these online activities, with trust perceptions as the most consistent predictor. Parental attitudes toward the Internet predicted parent-child differences in perceptions of how frequently the child used the Internet for help with homework and identity development, while the bioecology of the child was only predictive in the case of using the Internet for help with homework.  相似文献
