Educating the current and future workforce is an extremely important issue. Historically, the UK has not been concerned with educating and training the masses. In the 1990s, talent will be short in the UK and within the European Community (EC). By 1992, the trade barriers will be lifted for the 12 member nations of the EC. Companies that are creative and open to utilizing avenues to train present and potential workers are going to be more competitive in the EC. If the UK continues to produce an unskilled work force, it will not survive the competition. Business leaders realize the need to develop a work force that is equally or better equipped than the work force that is available to their competitors. core lessons learned from the international visit include (1) HRD is not a “perk,” (2) the changing work force is real, (3) quality is the key to competitiveness, and (4) managers need to stick to the basics of human resource management. 相似文献

The purpose of the study was to investigate which physiological parameters would most accurately predict a 6-min, all-out, double-poling (DP) performance in recreational cross-country skiers. Twelve male recreational cross-country skiers performed tests consisting of three series lasting 10 s, one lasting 60 s, plus a 6-min, all-out, DP performance test to estimate mean and peak power output. On a separate day, gross mechanical efficiency (GE) was estimated from a 10-min, submaximal, DP test and maximal oxygen consumption (VO2 max) was estimated from an incremental treadmill running test. Power was measured after each stroke from the acceleration and deceleration of the flywheel that induced the friction on the ergometer. The power was shown to the skier on a small computer placed on the ergometer. A multivariable correlation analysis showed that GE most strongly predicted 6-min DP performance (r = 0.79) and interestingly, neither DP VO2 max, nor treadmill-running VO2 max, correlated with 6-min DP performance. In conclusion, GE correlated most strongly with 6-min DP performance and GE at the ski ergometer was estimated to be 6.4 ± 1.1%. It is suggested that recreational cross-country skiers focus on skiing technique to improve gross mechanical efficiency during intense DP. 相似文献

Research has focused on parameters that are associated with injury risk, e.g. vertical acceleration. These parameters can be influenced by running on different surfaces or at different running speeds, but the relationship between them is not completely clear. Understanding the relationship may result in training guidelines to reduce the injury risk. In this study, thirty-five participants with three different levels of running experience were recruited. Participants ran on three different surfaces (concrete, synthetic running track, and woodchip trail) at two different running speeds: a self-selected comfortable speed and a fixed speed of 3.06 m/s. Vertical acceleration of the lower leg was measured with an accelerometer. The vertical acceleration was significantly lower during running on the woodchip trail in comparison with the synthetic running track and the concrete, and significantly lower during running at lower speed in comparison with during running at higher speed on all surfaces. No significant differences in vertical acceleration were found between the three groups of runners at fixed speed. Higher self-selected speed due to higher performance level also did not result in higher vertical acceleration. These results may show that running on a woodchip trail and slowing down could reduce the injury risk at the tibia. 相似文献

In this study the author surveys social studies standards from 14 U.S. states seeking to answer: (a) what social studies knowledge about American Indians is deemed essential by those states mandating the development of American Indian Education curricula for all public K–12 students? and (b) at what grade levels is this social studies content knowledge mandated in public K–12 schools? Document analysis, open-coding, and constant comparison revealed that the knowledge states standards require can be organized into six themes: identification/classification of tribes, distinct tribal cultures, contributions to mainstream U.S. culture, tribal government, connection to environment, and economics/occupations. The findings also revealed that the majority of standards relating to American Indians are directed to elementary grade levels. Standards in only two states, Maine and Montana, cover a breadth of curricular content and require that content coverage to continue K–12. 相似文献
