首次记载了毛冠菊属2种4居群的核形态资料。两种植物的染色体间期和前期染色体为复杂型
和中间型。狭舌毛冠菊两居群的染色体数目与核型公式为2n＝18＝14m+2sm+2st(2SAT);毛冠菊两居 群的染色体数目与核型公式为2n＝18＝14m+2sm(2SAT)+2st。它们分别代表了整个毛冠菊属的两组 植物,并包含了形态学上最原始的种类,因此,该属的染色体基数可能为x＝9。核形态证据表明毛冠菊属放在紫菀族比放在旋覆花族和千里光族中更为合理。 相似文献

To determine whether differential levels of anxiety and recall occur during vicarious modeling or self-observation, six counselor trainees were shown five videotaped segments of counselor-client interactions—two of a different counselor and client and three of themselves counseling (one of which was viewed in the presence of the trainees' supervising professor). Anxiety was measured by self-reports and hand temperature and recall was assessed by several questions regarding the verbal and nonverbal behaviors demonstrated in each segment. Although a significant negative correlation was found between the physiological measure of anxiety and recall (ρ = –.90), no significant differences were revealed in the amount of anxiety relative to other-model versus self-observation. Trainees recalled a significantly greater amount of verbal behaviors during other-model observation than in self-observation conditions, whereas the reverse was found for nonverbal behaviors. Additionally, the presence of the supervising professor effected a dramatic increase in anxiety and decrease in recall. 相似文献

The benefits of living and training at altitude (HiHi) for an improved altitude performance of athletes are clear, but controlled studies for an improved sea-level performance are controversial. The reasons for not having a positive effect of HiHi include: (1) the acclimatization effect may have been insufficient for elite athletes to stimulate an increase in red cell mass/haemoglobin mass because of too low an altitude (<2000-2200 m) and/or too short an altitude training period (<3-4 weeks); (2) the training effect at altitude may have been compromised due to insufficient training stimuli for enhancing the function of the neuromuscular and cardiovascular systems; and (3) enhanced stress with possible overtraining symptoms and an increased frequency of infections. Moreover, the effects of hypoxia in the brain may influence both training intensity and physiological responses during training at altitude. Thus, interrupting hypoxic exposure by training in normoxia may be a key factor in avoiding or minimizing the noxious effects that are known to occur in chronic hypoxia. When comparing HiHi and HiLo (living high and training low), it is obvious that both can induce a positive acclimatization effect and increase the oxygen transport capacity of blood, at least in 'responders', if certain prerequisites are met. The minimum dose to attain a haematological acclimatization effect is >12 h a day for at least 3 weeks at an altitude or simulated altitude of 2100-2500 m. Exposure to hypoxia appears to have some positive transfer effects on subsequent training in normoxia during and after HiLo. The increased oxygen transport capacity of blood allows training at higher intensity during and after HiLo in subsequent normoxia, thereby increasing the potential to improve some neuromuscular and cardiovascular determinants of endurance performance. The effects of hypoxic training and intermittent short-term severe hypoxia at rest are not yet clear and they require further study. 相似文献

This paper presents a comparative study of extra-musical learning in the music classes of the schools of Hong Kong and Taiwan, where education is geared towards democracy and citizenship at a time of unstable national identity for both communities. Taiwan has been undergoing a process of indigenisation since 1945, whilst Hong Kong's sovereignty was returned to the People's Republic of China after 1 July 1997. This paper argues that the transmission of extra-musical learning is essentially a response to the particular needs of these two Chinese historical-social contexts, which require their music curricula to be securely grounded in the ideology of a culturally based education for 'citizenship'. Despite different approaches to western-based musical knowledge in schools, Hong Kong and Taiwan attempt to promote a sense of national identity and an essentially Confucian set of moral values as a central goal of school music education. The promotion of ethno-cultural nationalism in Taiwan's music education is regarded as a democratic goal for the Taiwanese state, though in practice, the educational systems of both Taiwan and Hong Kong are coloured by the global context. 相似文献

研究主要的目的是了解大陆员工对于台商所给予的工作环境、工作教育训练以及工作薪资福利满意度现况,次要是想要探讨大陆员工的特质和忠诚度与工作教育训练及工作薪资福利之间有正向的关联性。随着2008年元月1日大陆的劳动合同法开始实施,台商所需要成本负担大幅提高,有了基本工资的保障,提升了大陆员工的生活质量,也影响了民生意识抬头,使得员工懂得捍卫自己的权利,尽管因为政府法规的实施有了许多变革之余,发现在薪资福利与忠诚度上有显著关系,且工作教育训练对于公司的忠诚度也有了显著关系,表示了大陆地区的员工逐渐重视了公司制度体系。研究在大陆鞋厂对于管理阶层以及基层员工发放问卷,以Cronbachs α值检定量表的信度、利用单因子变数分析员工人口因素在薪资福利及教育训练之间的差异性,在运用回归分析验证本研究所提出之研究假说。大陆经济起飞,尽管后来的新兴投资企业渐渐往越南、印度尼西亚发展,大陆依然是企业眼中的一块大饼,丰沛的人力则是企业最大资源。 相似文献
