This paper evaluates the relevance of innovation strategy to various categories of Chinese firms and investigates its relationship with innovation performance during the economic transition of the 1990s. Data from 1244 Chinese firms in Beijing are used to ascertain the relative importance of different innovation objectives, along with the innovation strategies adopted by manufacturing firms. Results show that innovation activities were confined to the domestic sphere and mainly directed at quality improvement. Chinese manufacturing firms which obtained support from the government through the high-tech firm accreditation system generally perform better. They had already started moving away from a reliance on imported technology and equipment, and using indigenous R&D efforts to innovate for the coming market economy.  相似文献   

法律上等位利益冲突的刑法评判     

赫洛·奥托 《华中科技大学学报(社会科学版)》2005,19(1):46-57

刑法上的等位利益冲突是在具体情形下予以评价的。包括作为义务冲突、不作为义务冲突及作为义务与不作为义务冲突三种情况。等位利益冲突在下述三种情况下是不违法的：（1）为了自己利益。不主动剥夺他人的机会,以此来提高自己的获救机会,同时行为人对他人并无特殊义务;（2）在不可能救助全部等位利益的情况下,救助了尽可能多的利益;（3）如果为了救助家庭成员而未考虑其他的救助义务,行为人为保全自己生命而转移危险,并且受威胁的家庭成员没有基于自由意思自找危险。  相似文献   

Youth Perspectives on Parental Career Influence   总被引：2，自引：0，他引：2  

Luther B. Otto 《Journal of Career Development》2000,27(2):111-118

The role of parents in youth career development is generally acknowledged though, often, perfunctorily. This inquiry examines youth perceptions of parental influence on their career development. We ask young men and women about specific career development attitudes and behaviors that bear on their relations with their parents. The sample consists of survey data from 362 high school juniors. The results confirm the trend of recent studies that report compatibility between parent and youth values, aspirations, and plans. Of all the people to whom youth can turn for help with making career plans, most look to their mothers. The findings apply across gender, to young men as well as young women; and they apply across race, to minority youth as well as majority-culture youth. The results underscore the importance of parents as allies and resources for career counselors in facilitating youth career development.  相似文献   

Ball launch conditions for skilled golfers using drivers of different lengths in an indoor testing facility     

Wallace ES  Otto SR  Nevill A 《Journal of sports sciences》2007,25(7):731-737

The displacement of the golf ball struck by a driving club is affected by several player characteristics and equipment parameters and their interrelationships. Some modelling and simulation studies have shown a relationship between shaft length and clubhead speed, supported by a few experimental studies. The aim of the present study was to examine the relationship between driver length and ball launch conditions in an indoor test facility using a ball launch monitor. Nine males considered to be skilled golfers participated in the study. Four driving clubs of total length 117, 119, 124, and 132 cm were assembled from commercially available components and were used to strike golf shots while initial ball velocity, backspin rate, and launch angles were measured. Statistical analysis identified a significant difference in initial launch speed due to club length, a significant difference between participants, but no difference between the trials for a given golfer. A positive trend was noted between backspin and launch angle for all four clubs, and significant inverse associations between initial launch speed and backspin rate and launch angle. However, the combined launch conditions associated with increasing length were not considered optimal, with uncontrolled swingweight and moment of inertia effects considered to be limiting factors.  相似文献   

The use of physiological, anthropometric, and skill data to predict selection in a talent-identified junior volleyball squad     

Gabbett T  Georgieff B  Domrow N 《Journal of sports sciences》2007,25(12):1337-1344

The aim of this study was to determine whether physiological, anthropometric, and skill test results could discriminate between junior volleyball players of varying ability. Twenty-eight junior volleyball players competed for selection in a talent-identification volleyball programme. Participants underwent measurements of stature, standing reach stature, body mass, skinfold thickness, overhead medicine ball throw, vertical jump, spike jump, 5-m and 10-m speed, "T" test agility, maximal aerobic power, and passing, setting, serving, and spiking technique and accuracy. A discriminant analysis was conducted on the selected and non-selected groups to obtain a regression equation that could be used to predict selection in junior volleyball squads based on the dependent variables. Passing and serving technique were the only significant variables included in the discriminant analysis. Cross-validation results showed that 17 of 19 selected players (89.5%) and 5 of 9 non-selected players (55.6%) were correctly classified into selected and non-selected groups, respectively, providing an overall predictive accuracy of 78.6%. The results of this study demonstrate that selected skill test results (i.e. subjective coach evaluations of passing technique and serving technique), but not physiological and anthropometric data, discriminate between successful and unsuccessful talent-identified junior volleyball players. These results demonstrate the importance of developing passing and serving technique in talent-identified junior volleyball players.  相似文献
