文中探讨了吸收能力对技术创新的影响及时间节奏在二者间的中介效应,构建了三者间的理论模型。基于珠三角企业221份有效调查问卷数据并进行了实证分析,研究结果表明:1潜在、现实吸收能力对渐进式创新与突破式创新具有显著正向影响;2潜在、现实吸收能力对时间节奏均有显著正向影响,时间节奏对渐进式创新和突破式创新有显著正向影响;3时间节奏在潜在吸收能力与渐进式创新二者关系中发挥了部分中介作用;在现实吸收能力与渐进式创新关系中以及在潜在、现实吸收能力与突破式创新关系中均发挥了完全中介作用。 相似文献

Historians use a range of genres in presenting their subjects, yet educators have increasingly privileged argumentation to help novices to reason with historical content. However, the influence genre and content knowledge are relatively unmeasured in this discipline. To learn more, the authors asked 101 eleventh-grade students to compose an argument or a summary on the Gulf of Tonkin and analyzed basic and disciplinary reading and writing measures. Results indicate that students with adequate content knowledge performed better on a disciplinary reading measure when composing arguments, and students with limited content knowledge demonstrated greater comprehension when composing summaries. Students with more knowledge wrote more; however, students who wrote summaries were not disadvantaged in terms of level of historical thinking or overall quality. Last, providing students with disabilities with a simple reading accommodation afforded them the ability to participate in the disciplinary literacy task at levels comparable to their peers. 相似文献

A randomized controlled trial was conducted to examine eight weeks of resistance training (RT) with and without time-restricted feeding (TRF) in order to assess nutrient intake and changes in body composition and muscular strength in young recreationally active males. The TRF programme consisted of consuming all calories within a four-hour period of time for four days per week, but included no limitations on quantities or types of foods consumed. The RT programme was performed three days per week and consisted of alternating upper and lower body workouts. For each exercise, four sets leading to muscular failure between 8 and 12 repetitions were employed. Research visits were conducted at baseline, four, and eight weeks after study commencement. Measurements of total body composition by dual-energy X-ray absorptiometry and muscle cross-sectional area by ultrasound were obtained. Upper and lower body strength and endurance were assessed, and four-day dietary records were collected. TRF reduced energy intake by ~650?kcal per day of TRF, but did not affect total body composition within the duration of the study. Cross-sectional area of the biceps brachii and rectus femoris increased in both groups. Effect size data indicate a gain in lean soft tissue in the group that performed RT without TRF (+2.3?kg, d?=?0.25). Upper and lower body strength and lower body muscular endurance increased in both groups, but effect sizes demonstrate greater improvements in the TRF group. Overall, TRF reduced energy intake and did not adversely affect lean mass retention or muscular improvements with short-term RT in young males. 相似文献
