Studies investigating sport socialisation often focussed on the barriers for youngsters from lower socio-economic status (SES) families to participate in sport. In the present study, the socialisation into sports of young adolescents from lower SES families that do participate in organised sports was investigated. A total of 9 girls and 12 boys from lower SES families (18 Dutch; three foreign ethnic background) from one city in the Netherlands who participated in organised sport were interviewed. Although multiple agents may be of influence on the socialisation process, this study was limited to the family, school and peers as potential socialising contexts. Drawing on the theoretical work of Bourdieu and Bernstein, parents were found to be the main influencers of the sports habitus of these young adolescents. The school context appeared to have no influence on their sport socialisation. Peers were found to have an influence on the choice for a specific type of sport. This interplay between socialising contexts for young adolescents from lower SES families is similar to the sport socialisation of youngsters from higher SES families. Therefore, it is suggested that if sport socialisation takes place, then the role of SES is less pronounced than often assumed. Moreover, there seem to be differences in the relative importance of the socialising contexts with younger children with a lower SES. Therefore, it is hypothesised that the relative importance of socialising agents changes over time. Although the findings may be limited to the specific sample of this study, they provide hypotheses that challenge the often-presumed importance of SES if sport socialisation takes place. 相似文献

在对各种技术道德研究路径进行分析的基础上,展开对技术是否可以作为道德行动者的审视,并从道德调节入手,以对构成道德能动性的两个必要条件——意向性和自由——的非人文主义分析为基础,重新思考伦理学中物的地位,借助于阐述物在道义论、目的论、美德论伦理学中的作用来创建认真对待技术道德相关性所需要的空间,即通过道德调节来有效构建通向将技术道德化的理论途径。 相似文献

传统技术道德问题的思考主要表现在对技术所具有的道德调节作用上的分析,即技术如何调节人类的道德行为。这一传统方式主要基于人本主义的设定,即人与技术之间存在着严格边界,人具有道德自主性,技术是无自主性的。但是会聚技术、大脑植入、智能环境等新技术带来的根本问题逐步取消人与技术之间的严格边界,技术与身体彼此融合介入,并且以新的形式影响着人类道德决策。理解这些问题,必须采取超人类主义的态度,必须超越传统的技术道德调节形式。新技术给人类带来了两种新型关系:赛博格关系与复合关系。只有在超人类主义的基础上,才能够有效分析新技术与人之间所呈现出来的新型关系——赛博格关系、复合关系——及其道德意蕴。 相似文献

Conceptions are analyzed as being the emergences from interactions between three poles： scientific knowledge （K）, values （V） and social practices （P）. The teachers＇ beliefs and values have a direct influence on the way of understanding and teaching a topic. These beliefs must be taken into account in the content and strategies of the teacher＇s formation. In this paper, the authors discuss the importance of studying and analyzing these conceptions and present the results of the research on teachers＇ and future teachers＇ conceptions about sexual health education. In this topic, the conceptions could be deeply rooted not only in scientific knowledge but also in value systems and social practices, because teachers often refuse to teach the ethical, psychological, economic and social issues not strictly reducible to biology, such as sexuality health. The authors used a questionnaire prepared jointly within the European project Biohead-Citizen. 相似文献

The goal of this study was to determine the stability of Total Prostrate Specific antigen (PSA-T) and Free Prostrate Specific
Antigen (PSA-F) in archival serum stored at 4°C and −20°C and subjected to temperature shift due to interruption in power
supply. Our study showed that PSA-T was stable up to 285 days and PSA-F was stable for 158 days under these conditions. Since
power supply interruption is an unavoidable problem in developing nations, our study has implication on the validity of measurement
of PSA-T and PSA-F in serum that was not properly stored due to emergency situations and for certain types of retrospective
studies. 相似文献

The effects of test stimulus range on generalization gradients in humans were assessed for discriminations between faces that
varied in brightness, faces that varied in orientation in the picture plane, and morphed faces. In Experiment 1, significant
range effects, predicted by adaptation level theory, occurred when faces varied along the brightness or orientation dimension,
but not for morphed faces. Changing the difficulty of discrimination of both training and test stimuli for Experiment 2 produced
range effects in morphed faces. Experiment 3 explored training and testing stimulus factors as determinants of range effects
in morphed faces. The results suggest that sufficiently biased testing ranges create shifts in response distributions (generalization
gradients), and this may be amplified by using relatively difficult discriminations between training stimuli. 相似文献

The level of seven acute phase proteins was estimated together with copper and zinc in two groups of 15 children each suffering
from hepatitis A (HAV) or Hepatitis B (HBV). The mean concentration of α-1 antitrypsin, α-2 macroglobulin, ceruloplasmin,
C3 and copper was increased uniformly in both the types of viral hepatitis. α-1 acid glycoprotein, haptoglobin and zinc levels
were decreased in both the infections. A significant decrease in albumin level was observed in HAV while the decrease was
not significant in HBV. All the paramenters were repeated after one month on the day of discharge following the disappearance
of clinical signs and symptoms wherein the haptoglobin level returned to normal in HAV. No change was observed in the level
of other acute phase proteins. The level of the trace elements returned to normal. The observed increase in the levels of
acute phase proteins at the onset does not seem to have any significant relation to the subsequent course of the disease.
However, the level of acute phase proteins and other biochemical parameters may indicate a delayed biochemical recovery phase
in conjunction with the underlying hepatic pathological changes in the course of viral hepatitis in spite of clinical recovery. 相似文献

Wage differential studies examining legally protected groups typically focus on gender or racial differences. Legislation also fully protects individuals with learning disabilities (LD). This article is the first to decompose wage differentials between adults with and without LD. An original data set of college graduates with documented LD was constructed, and these individuals were compared to a control group from the National Longitudinal Survey of Youth (NLSY). Our results show that much of the observed lower wages for individuals with LD is due to differences in productivity characteristics. However, there is an unexplained portion of the wage gap that could possibly be considered wage discrimination against individuals with LD. This possibility seems smaller due to the fact that the subsample of the employers who knew of the employee's learning disabilities did not appear to pay significantly lower wages to these individuals. Alternative hypotheses are discussed, as are sample-specific issues. 相似文献

In the general population, estimates of left-foot preference are around 20%. In soccer, specific tasks create positional demands, requiring 40% of the players to be left-footed. Whether and how this is related to the selection of players is unknown. To examine the successive selection of soccer players for Dutch national youth teams in relation to foot preference, 280 youth players (age = 16.2 ± 1.08 years) were monitored from the U16 through the U19 teams over the last 5 years. No difference in successive selection between left- and right-footed players was found (p < 0.05). Regardless of foot preference, more than 50% of the selected players were deselected out of a national youth team after 2 years. On average, 31% of the national youth players were left-footed, which is higher than expected, based on population estimates (χ2 (1) = 37.49, p < 0.001, w = 0.27). However, there was an under-representation of left-footed players, based on expected positional demands (i.e., attack, midfield, defence) (χ2 (1) = 16.83, p < 0.001, w = 0.18). The conclusion is that left-foot preference increases the probability of selection in Dutch national youth soccer teams. 相似文献
