Abstract This paper investigates the conditions of the manufacture of low‐cost technology in China with the examples of ‘pirated’ VCD players, ‘no‐name’ DVD players, and Shenzhen’s development as a techno‐urban city. It emphasizes the significance of the cultural logic of original equipment manufacturers (OEMs) and argues that the various transformations and deflections that are derived from ubiquitous OEM experiences have gone beyond the original model of an authorized OEM, experiences that are to some extent embodied in the transgression of brand name and patent hegemonies, which are mainly controlled by high technology companies. OEMs have been associated with China’s current imperative and uninhibited development of low‐cost technology capitalism. ‘Made in China’ signifies the production of any product, legal or illegal, for transnational high technology giants or domestic technology manufacturers. Learning to ‘become an OEM’ in China has partly resulted in excessive technological mimesis that may be part of an unauthorized, underground economy that is based on low‐cost technology. Based on the Shenzhen experience, part of this study will show industrial production‐oriented OEM cultures in which illegal operations and counterfeit trade are incorporated, even in city projects that are shared by municipal governments and Chinese technological companies, and undergo spatial restructuring in the development of the economy, consumerism, and urbanism. 相似文献

Research Findings: The purpose of this study was to examine differences in the development of conflict management strategies, focusing on 3- and 5-year-olds, through a comparison of 3 neighboring Asian cultures, those of China (n = 114), Japan (n = 98), and Korea (n = 90). The dual concern model of conflict management was adopted to probe which strategy children would prefer to use in 2 hypothetical conflict situations. Results indicated that, first, for disagreement, 3-year-olds in the 3 countries equally preferred the dominating strategy. For competition for resources, 3-year-olds differed in their strategy preference across all cultures. Second, the observed strategy preference of 3- to 5-year-old children in this study was more or less different from that of older schoolchildren, regardless of culture. Practice or Policy: These findings suggest the significance of the context, the complexity of the phenomenon of the development of cultural differences, and the significance of cohort sampling. 相似文献

This paper describes the development of a software program that supports argumentative reading and writing, especially for novice students. The software helps readers create a graphic organizer from the text as a knowledge map while they are reading and use their prior knowledge to build their own opinion as new information while they think about writing their essays. Readers using this software can read a text, underline important words or sentences, pick up and dynamically cite the underlined portions of the text onto a knowledge map as quotation nodes, illustrate a knowledge map by linking the nodes, and later write their opinion as an essay while viewing the knowledge map; thus, the software bridges argumentative reading and writing. Sixty-three freshman and sophomore students with no prior argumentative reading and writing education participated in a design case study to evaluate the software in classrooms. Thirty-four students were assigned to a class in which each student developed a knowledge map after underlining and/or highlighting a text with the software, while twenty-nine students were assigned to a class in which they simply wrote their essays after underlining and/or highlighting the text without creating knowledge maps. After receiving an instruction regarding a simplified Toulmin’s model followed by instructions for the software usage in argumentative reading and writing along with reading one training text, the students read the target text and developed their essays. The results revealed that students who drew a knowledge map based on the underlining and/or highlighting of the target text developed more argumentative essays than those who did not draw maps. Further analyses revealed that developing knowledge maps fostered an ability to capture the target text’s argument, and linking students’ ideas to the text’s argument directly on the knowledge map helped students develop more constructive essays. Accordingly, we discussed additional necessary scaffolds, such as automatic argument detection and collaborative learning functions, for improving the students’ use of appropriate reading and writing strategies.

We tested the hypothesis that work-matched supramaximal intermittent warm-up improves final-sprint power output to a greater degree than submaximal constant-intensity warm-up during the last 30?s of a 120-s supramaximal exercise simulating the final sprint during sports events lasting approximately 2?min. Ten male middle-distance runners performed a 120-s supramaximal cycling exercise consisting of 90?s of constant-workload cycling at a workload corresponding to 110% maximal oxygen uptake (VO2max) followed by 30?s of maximal-effort cycling. This exercise was preceded by 1) no warm-up (Control), 2) a constant-workload cycling warm-up at a workload of 60%VO2max for 6?min and 40?s, or 3) a supramaximal intermittent cycling warm-up for 6?min and 40?s consisting of 5 sets of 65?s of cycling at a workload of 46%VO2max?+?15?s of supramaximal cycling at a workload of 120%VO2max. By design, total work was matched between the two warm-up conditions. Supramaximal intermittent and submaximal constant-workload warm-ups similarly increased 5-s peak (590?±?191 vs. 604?±?215W, P?=?0.41) and 30-s mean (495?±?137 vs. 503?±?154W, P?=?0.48) power output during the final 30-s maximal-effort cycling as compared to the no warm-up condition (5-s peak: 471?±?165W; 30-s mean: 398?±?117W). VO2 during the 120-s supramaximal cycling was similarly increased by the two warm-ups as compared to no-warm up (P?≤?0.05). These findings show that work-matched supramaximal intermittent and submaximal constant-workload warm-ups improve final sprint (～30?s) performance to similar extents during the late stage of a 120-s supramaximal exercise bout. 相似文献

The task here is to consider what I would call Stuart Hall’s theoretical “legacy” in the field of social and cultural thoughts. As a materialist of articulation rather than of reductionism, Hall taught us how to profoundly understand and intensely describe the “concrete” in cultural and social fields. The “concrete,” according to Hall, is a result of “non-necessary correspondence” between various forces, relations and situations, that is, the contingent and articulated determination in history. In my view, he was after all a Marxist in this sense. In the earlier stage of his thinking, Hall was very much indulged in reading and learning from Marx. This is characteristic in his “Marx’s Notes on Method: A Reading of the 1857 ‘Introduction.’” His Marxism then showed a unique twist in later stage, which was explicitly expressed in his article “Signification, Representation, Ideology: Althusser and the Post-Structuralist Debate.” Reading these two texts, I aim to comprehend the way Hall has read Marx and the way his thoughts resonated. His lesson helps us to tackle our ongoing agendas in this half-dead Capitalist world, such as the crisis of culture, subjectivity and politics. 相似文献

不同方式刺激与运动训练的成骨作用机理研究 总被引：3，自引：0，他引：3
对低频振动,牵张应力,剪切应力,超声波,光、电刺激,药物刺激的成骨作用及其生物学机制和运动促进的成骨作用研究进展进行文献梳理。结果表明,低频振动,牵张应力,剪切应力,超声波,光、电刺激,药物刺激均可刺激成骨作用的发生和发展。其生物学机制主要通过骨组织感受力学刺激——应力敏感通道和整合素-细胞骨架结构完成。机械负荷可以激活细胞膜上Ca2 通道引起胞外Ca2 内流,并可促进胞内Ca2 释放,从而促进骨的合成代谢作用。力学信号的转导过程包括力学偶联、生化偶联、信号转导和受体细胞应答等4个阶段。细胞因子和激素含量变化对胞内信号转导有重要影响,如OPG、TGF-β、IGF、甲状旁腺素(PTH)、雌激素、PGE2等。运动可促进骨生长发育,但不同运动方式及其运动强度对骨促进作用是不同的;运动对老年骨质疏松症,特别是女性绝经期后因雌激素分泌减少导致骨丢失的防治起重要作用。 相似文献

The aims of this study were to investigate the effects of a 4-week intervention of static stretching (SS) on muscle hardness of the semitendinosus (ST), semimembranosus (SM) and biceps femoris (BF) muscles. Shear elastic modulus was measured by using ultrasound shear wave elastography as the index of muscle hardness. Thirty healthy men (age 22.7 ± 2.2 years) volunteered for this study and were randomly assigned to the SS intervention group (n = 15) or the control group (n = 15). Participants in the SS intervention group received a 4-week stretch intervention for the hamstrings of their dominant leg. Shear elastic moduli of the hamstrings were measured at initial evaluation and after 4 weeks in both groups at a determined angle. In all muscles, the shear elastic modulus decreased significantly after SS intervention. The percentage change in the shear elastic modulus from the value at initial evaluation to after 4 weeks intervention was greatest in the SM. These results suggest that SS intervention has chronic effects on reducing hardness of the hamstring muscle components, especially the SM muscle. 相似文献
