This study investigated the acute endocrine responses to a 164-km road cycling event in a hot environment. Thirty-four male experienced cyclists (49.1 ± 8.3 years, 86.8 ± 12.5 kg, 178.1 ± 5.1 cm) participating in a 164-km road cycling event were recruited. Blood samples were collected within 0.3–2.0 h before the start (PRE: ~0500–0700 h) and immediately following the ride (POST). Samples were analysed for testosterone, growth hormone (GH), cortisol and interleukin-6 (IL-6). The temperature and humidity during the event were 35.3 ± 4.9°C and 47.2 ± 14.0%, respectively. Based on the finishing time, results for the fastest (FAST, 305 ± 10 min) and the slowest (SLOW, 467 ± 31 min) quartiles were compared. At POST, testosterone concentration was significantly (P < 0.05) lower (PRE, 20.8 ± 8.6; POST, 18.2 ± 6.7 nmol · L?1), while GH (PRE, 0.3 ± 0.1; POST, 2.3 ± 0.3 µg · L?1), cortisol (PRE, 661 ± 165; POST, 1073 ± 260 nmol · L?1) and IL-6 (PRE, 4.0 ± 3.4; POST, 22.4 ± 15.2 pg · mL?1) concentrations were significantly higher than those at PRE. At POST, GH and cortisol were significantly higher for the FAST group than for the SLOW group (GH, 3.6 ± 2.0 and 1.0 ± 0.8 µg · L?1; cortisol, 1187 ± 209 and 867 ± 215 nmol · L?1). Participation in an ultra-endurance road cycling event in a hot environment induced significant acute changes in concentrations of circulating hormones, with a greater augmentation of GH and cortisol in those completing the ride fastest. 相似文献

Field independent students are generally expected to perform better academically than those who are field dependent, and this is particularly marked in distance learning where students learn without the traditional support offered in conventional instruction. In this paper two studies of the relationship between field dependence and academic learning in the context of distance learning are reported with Bachelor of Health nursing students in Hong Kong. In both studies field independent nurses performed significantly better than field dependent ones. Some implications of these findings for distance learning are discussed. 相似文献

Personal and social education has become an important area of development in education in Hong Kong. Given that much of the literature on personal and social education is Anglo-American or European, what is the influence on the largely Chinese settings in Hong Kong? This paper will examine some of the debates of what constitutes personal and social education. The significance of competing contexts in the development of personal and social education will be analysed in detail. Comparisons will be made between Western and Chinese (especially Confucian) views on personal and social education. Attempts will be made to come up with a notion of personal and social education which is suitable for the Hong Kong context. 相似文献

This paper examines teachers' stories of children's coping with changing family situations such as divorce or family separation which can induce discontinuities in their lives. Using the case of Hong Kong, a place where ‘East meets West’ in cultures and family relationships, this paper argues for the use of the concept of hybridities in understanding the experiences of children in changing family situations. Teachers' stories show that children in changing family situations are facing new kinds of difficulties from the mixing of modern family forms and traditional family values. Implications to teacher education, policy and practice are suggested. 相似文献

This study focuses on the visual collections in the holdings of the Slavonic Library (a section of the National Library of the Czech Republic). The library holdings also include unique collections relevant to the topic of Russian and Ukrainian emigration: collections of visual art, ex libris, posters and flyers by Ukrainian émigrés (1918–1945), and a collection of invitations and flyers by Russian émigrés (1918–1945). Rudolf H?lka’s collection of photographs, dating back to the 1920s, captures a series of ethnographic, folkloric, and architectonic phenomena which no longer exist. Moreover, Russian posters from the period of WWI, from the revolutionary year of 1917, and the subsequent civil war are equally fascinating as are banknotes from the same period and region. 相似文献

This paper discusses various issues about the rank equivalence of Lafferty and Zhai between the log-odds ratio and the query
likelihood of probabilistic retrieval models. It highlights that Robertson’s concerns about this equivalence may arise when
multiple probability distributions are assumed to be uniformly distributed, after assuming that the marginal probability logically
follows from Kolmogorov’s probability axioms. It also clarifies that there are two types of rank equivalence relations between
probabilistic models, namely strict and weak rank equivalence. This paper focuses on the strict rank equivalence which requires
the event spaces of the participating probabilistic models to be identical. It is possible that two probabilistic models are
strict rank equivalent when they use different probability estimation methods. This paper shows that the query likelihood,
p(q|d, r), is strict rank equivalent to p(q|d) of the language model of Ponte and Croft by applying assumptions 1 and 2 of Lafferty and Zhai. In addition, some statistical
component language model may be strict rank equivalent to the log-odds ratio, and that some statistical component model using
the log-odds ratio may be strict rank equivalent to the query likelihood. Finally, we suggest adding a random variable for
the user information need to the probabilistic retrieval models for clarification when these models deal with multiple requests. 相似文献

This paper presents findings on a hybrid guidance curriculum in Hong Kong, a place where East meets West in education and
in many other spheres. A qualitative case study method is applied that uses questions for understanding the ‘self’ in guidance
but incorporates Confucian cardinal human relationships of parent–child, brother–sister, husband–wife, superior–subordinate,
teacher–pupil and friend–friend in understanding the ‘other’ relationships. The study of ‘self–other relationship’ is combined
with Lawton’s (Social change, educational theory and curriculum planning, Hodder, London, 1973) model of curriculum development in Western traditions. Data obtained from stakeholders in schools include traditional Chinese
ideas as well as modern Western ideas. Implications of this framework to the study of other societies with a mix of Western
and traditional cultures are discussed.

This paper looks at the developmental needs of teachers in relation to facilitating the personal and social development of students. It goes on to describe a module, 'Personal and Social Education', offered to all pre-service teachers in the Hong Kong Institute of Education which aims at equipping trainee teachers to carry out the guidance role of a teacher in the context of Hong Kong, particularly in the role of a class teacher. It concludes with the results of a survey seeking the views of these trainees on the module they had undertaken. 相似文献
