制度作用下大学科研人员产学合作模式选择的扎根研究     

张慧颖  连晓庆 《科学学与科学技术管理》2015,(3):163-171

通过对大学科研人员的深入访谈,运用扎根理论的研究方法,探索性地构建了对大学科研人员产学合作模式选择产生影响的直接制度和间接制度;研究发现,直接制度在大学科研人员的产学活动中发挥的效应为零,与直接制度相比,间接制度对大学科研人员产学活动的影响更为明显。结果表明政策制定者需要进一步疏通政策的传导机制,强化政策的执行力,进而提高大学科研人员产学合作的积极性。  相似文献   

新经济环境下技术创新驱动与品牌关系驱动影响力对比研究     

唐小飞  成立  王春国  鲁平俊 《科研管理》2015,36(11):176-183

受中国传统文化的影响和关系营销在世界范围内的兴起,品牌关系营销作为中国商业市场的基础变量的地位在全社会形成共识。因此,通过品牌关系驱动顾客忠诚和品牌资产成为客户关系管理和品牌资产管理的基本逻辑与理性认知。然而,随着新一轮科技革命与产业变革的孕育兴起,品牌关系驱动能否成功应对技术创新驱动对品牌关系情感与顾客购买意愿的冲击?品牌资产的基本理论模型是否还能有效地指导新兴市场的商业实践,抑或需要重构?这些问题值得深入探究。本文以手机品牌消费者为样本,研究发现:表性特征层面,消费者逻辑仍遵循"品牌原型—品牌关系情感—购买意愿"的发展路径。本质特征层面,消费者逻辑受到外力的驱动发生改变,且与品牌关系驱动相比,技术创新驱动所发挥的调节作用更大。研究结论在一定程度上颠覆了传统的关系营销理论模型,对企业在新经济环境下的营销战略具有重要启示和指导意义。  相似文献   

创新是发展的根本动力

创新是一个复杂的价值创造过程,是经济发展的决定性力量。创新驱动发展涉及现代化建设的方方面面,包括科学技术创新、商业模式创新、制度创新、管理创新和社会创新以及人才培养机制创新。为实现创新驱动发展,需要完善国家创新生态系统,加速政府职能转变,着力营造良好的创新制度文化环境,激发创新主体的创新活力,强化创新基础条件平台建设,弘扬中华民族的创新文化和创新精神,形成全社会关心创新、参与创新的良好发展局面,加快建设创新型国家和全面建成小康社会。  相似文献   

Perform kicking with or without jumping: joint coordination and kinetic differences between Taekwondo back kicks and jumping back kicks     

Kuangyou B. Cheng  Ying-Hsun Wang  Shih-Yu Kuo  Kuan-Mao Wang  Yi-Chang Huang 《Journal of sports sciences》2015,33(15):1614-1621

We investigated joint coordination differences between Taekwondo back kicks and jumping back kicks, and how jumping (in performing the latter) would alter engaging ground reaction forces (GRF) in executing kicking. Ten skilful athletes volunteered to perform both kinds of kicking within the shortest time for three successful trials. Three high-speed cameras and two force platforms were used for data collection, and the trial with the shortest execution time was selected for analysis. Movements were divided into the rotation and attack phases. With comparable execution time and maximum joint linear/angular speeds, back kicks and jumping back kicks differ mainly in larger GRF in the latter, and in greater target acceleration in the former probably because the support leg prevented athletes’ rebounding after impact. In addition, more prominent antiphase and in-phase coordination between the shoulder segment and knee joint, and elongated rotation phase were found in jumping back kicks. Larger GRF values in jumping back kicks were generated for jump take-off rather than for a more powerful attack. In back kicks although the support leg remained ground contact, greatly decreased GRF in the attack phase suggested that the support leg mainly served as a rotation axis.  相似文献   

Validation of two accelerometers to determine mechanical loading of physical activities in children

The purpose of this study was to assess the validity of accelerometers using force plates (i.e., ground reaction force (GRF)) during the performance of different tasks of daily physical activity in children. Thirteen children (10.1 (range 5.4–15.7) years, 3 girls) wore two accelerometers (ActiGraph GT3X+ (ACT), GENEA (GEN)) at the hip that provide raw acceleration signals at 100 Hz. Participants completed different tasks (walking, jogging, running, landings from boxes of different height, rope skipping, dancing) on a force plate. GRF was collected for one step per trial (10 trials) for ambulatory movements and for all landings (10 trials), rope skips and dance procedures. Accelerometer outputs as peak loading (g) per activity were averaged. ANOVA, correlation analyses and Bland–Altman plots were computed to determine validity of accelerometers using GRF. There was a main effect of task with increasing acceleration values in tasks with increasing locomotion speed and landing height (P < 0.001). Data from ACT and GEN correlated with GRF (r = 0.90 and 0.89, respectively) and between each other (r = 0.98), but both accelerometers consistently overestimated GRF. The new generation of accelerometer models that allow raw signal detection are reasonably accurate to measure impact loading of bone in children, although they systematically overestimate GRF.  相似文献   

论辅导员群体习性与职业环境的冲突——辅导员职业动力不足原因分析     

冯建 《绵阳师范学院学报》2015,(3):105-108

年轻、专职、高学历的群体特征及特殊的求职体验造就了辅导员特殊的群体习性,即理想化、高成就动机和强烈的自我证明意识。而辅导员职业场域在高校场域中的边缘位置和场域的不成熟性,决定了多数辅导员既无法凭借本场域的资源向更高权力场域流通,又很难凭借本场域满足自身的习性要求,辅导员职业动力不足恰是上述矛盾关系的反映。  相似文献   

契约文书中的宗族参与——以江西地区为中心     

彭志才  曾敏  高劲松 《衡水学院学报》2015,(2):105-109

清代至民国时期,宗族势力参与契约文书最主要、最直接的表现,就是在个人签订各种契约文书的过程中,往往需要得到宗族的认可或批准。在土地等财产的流转过程中,宗族势力或直接成为交易行为的主导者,利用说合中人和亲邻的角色施加影响,参与并直接影响交易过程;或是作为宗族财产的支配者对众存产业进行管理,参与家产的处分;或是作为交易行为的见证者,以见卖人、在场人的身份行使知情权和监督权,对交易过程施以间接影响。  相似文献   

0Cr18Ni9不锈钢车削力试验研究     

王文龙  马利杰 《河南科技学院学报》2015,(1)

切削力是切削加工中的一种伴随现象,切削力的大小直接影响到刀具寿命、加工质量和加工效率。在分析车削力时域特征的基础上,通过0Cr18Ni9不锈钢的正交车削试验,研究了切削参数对切削力波动系数的影响规律。结果表明：动态性是车削力的基本属性,切向分力和进给分力是车削力的主要成分;切削用量三要素中,切削深度ap对进给分力波动系数Qf和切向分力波动系数Qc都有着显著的影响,两者随ap的变化趋势基本一致。  相似文献   

王夫之对孙子军事思想的继承与发展     

李兆禄 《滨州学院学报》2011,27(5):20-30

王夫之以儒家思想为基础,借鉴吸收孙子军事思想,并对其加以继承发展。王夫之继承孙子"慎战"思想,对战争持审慎态度,认为要兴盛取胜,必须推行仁德,这才是兴国治军之根本。继承发展孙子"任势"思想,强调作战要因势制敌。继承发展孙子"五事"中"法"的思想,重视足食足兵,教兵备战。此外,王夫之还发展了孙子有关主、将、卒的作用和相互关系思想,重谋思想以及奇正思想。王夫之的军事思想是在吸收以孙子兵法为代表的优秀传统军事思想的基础上形成的,是我国传统军事思想的一个重要组成部分。  相似文献   

析论廖仲恺的民主宪政思想     

董立山 《衡阳师范学院学报》2011,32(1):111-114

廖仲恺是我国著名的资产阶级民主革命家,一生追求"国基巩固,民生乐利",鼓吹"全民政治"。在其一系列政论性文章及讲演中,蕴含着深刻的宪政思想,是我国二十世纪初宪政思想宝库中一颗璀璨的明珠。其宪政思想主要包括:民主国家的主权总是在人民;直接民权是弥补国会代议制弊端的不二法门;自由的实现需要有实质性内容的保障;平均地权是实现经济民权的手段等方面。  相似文献
