This study examines to what extent assessment of text comprehension involves knowledge of the properties of human cognition (theory of mind) and the social context of assessment. The subjects (N=332) were asked to read a text and then assess eight answers to questions about this text. The independent variables were the quality of the answers to requests for paraphrases, the quality of answers to direct questions about the meaning of the text, the order of the paragraphs in the text and the human vs. artificial source attributed to the answers. Results show that answers to requests for paraphrases were thought to be better when the source was artificial rather than human. Inversely, answers to direct questions about the meaning of the text were thought to be better when their source was human. The assessment of answers attributed to a human source were differentiated by a greater integration of contiguous assessments (contrast effect between contiguous assessments). This was noted more particularly for a person than for a machine, poor paraphrasing being followed by a better assessment of answers to questions about the meaning of the text. The assessment of human understanding of a text is hypothesised to be guided by an expectation of answer coherency and a wider and more structured knowledge than the assessment of artificial answers. 相似文献

Abstract The aim of this study, carried out in association with beef cattle producers, was to explore the capacity of farms to adapt, from a techno-conomic point of view, to both structural changes in consumer demand for beef products and market disruptions (sudden drop in beef consumption due partly to media coverage of bovine spongiform encephalopathy [BSE] and foot-and-mouth disease in the winter 2000/2001). The aim is to help farmers and advisors to find solutions to fit farmers’ management choices with their strategic objectives. The flexibility concept was adopted in order to examine how farms reacted to the winter 2000/2001 crisis, and was based on several technical, economic and sociological surveys. A series of variables was proposed and several hypotheses were formulated regarding their impact on farm flexibility. Four types of farm strategy were identified using different combinations of the degree of importance of these variables, with technical, economic and marketing flexibilities specific to each type. The results revealed the different combinations of flexibility-types possible (technical, economic, marketing) and explain why cattle farmers reacted as they did. Analysis of farm flexibility also revealed situations where these technical, economic and marketing flexibilities were either complementary or incompatible. For traditional livestock farmers, high flexibility (technical and economic) allowed them to minimize the impact of the crisis on their systems. In other cases, low flexibility either resulted in inertia, or led farmers to react by seeking solutions outside the cattle farming system. Development groups should take into account these parameters when interacting with farmers. We propose a framework to qualify the use of information resources by farmers, relative to their flexibility. 相似文献

The aim of this study was to determine whether there is an effect of time of day on the adaptation to strength training at maximal effort. Fourteen participants took part in this experiment. Their peak anaerobic power (Wingate anaerobic test) and peak knee extension torque at six angular velocities (1.05, 2.10, 3.14, 4.19, 5.24 and 6.29 rad · s -1 ) were recorded in the morning (between 07:00 and 08:00 h) and in the evening (between 17:00 and 18:00 h) just before and 2 weeks after a 6 week course of regular training. Seven of them trained only in the morning and seven only in the evening. Multivariate analysis of variance revealed a significant group 2 pre-/post-training 2 time of day interaction effect for peak torque and peak anaerobic power. Before training, in both groups, peak torque and peak anaerobic power were significantly higher in the evening than in the morning. After training, there was no significant difference in peak torque and peak anaerobic power between the morning and the evening for the morning training group. In contrast, in the evening training group, peak torque and peak anaerobic power were higher in the evening than in the morning. As a result of training, both peak torque and peak anaerobic power increased from their initial values as expected. The morning training group improved their peak anaerobic power significantly in the morning and in the evening, the absolute increase being larger in the morning than in the evening. The evening training group did not improve their peak anaerobic power in the morning, whereas it improved significantly in the evening. Although peak torque was significantly improved by training in the morning and evening in both groups, the absolute increase was greater in the morning than in the evening in the morning training group, whereas the opposite was the case for the evening training group. These results suggest that training twice a week at a specific hour increases the peak torque and the peak anaerobic power specifically at this hour and demonstrates that there is a temporal specificity to strength training. 相似文献

Abstract Thermoneutral water immersion increases cardiac preload and changes the neuroendocrine settings of blood volume regulation. The resulting marked diuresis may lead to significant haemodynamic changes after the end of a prolonged water immersion. Ten volunteers underwent 6 h of complete thermoneutral water immersion. Changes in cardiovascular status were assessed 1 h and 16 h after water immersion. Haemodynamic changes were assessed by Doppler echocardiography. Arterial wall distensibility was estimated by pulse wave velocity analysis. One hour after water immersion, mean weight loss was 1.78 kg and urine volume amounted to 1.5 litres. Echocardiographic measurements evidenced a significant decrease in dimensions of the left cardiac chambers and inferior vena cava. The decreased cardiac preload was paralleled by a lower stroke volume and cardiac output. A peripheral vasoconstriction associated with a relative decrease in the lower limb blood flow was evidenced by an increase in carotid-pedal pulse wave velocity and by a decrease in ankle brachial index. Sixteen hours after water immersion, cardiac preload and cardiac output remained below baseline values and peripheral vascular tone was still higher than at baseline. Marked haemodynamic changes had not returned to baseline 16 h after water immersion. There is a need to design fluid-replacement protocols to improve this recovery. 相似文献

The aim of this study was to determine the effects of external loading on power output during a squat jump on a force platform in athletes specializing in strength and power events (6 elite weight-lifters and 16 volleyball players) and in 20 sedentary individuals. Instantaneous power was computed from time-force curves during vertical jumps with and without an external load (0, 5 or 10 kg worn in a special vest). The jumps were performed from a squat position, without lower limb counter-movement or an arm swing. Peak instantaneous power corresponded to the highest value of instantaneous power during jumping. Average power throughout the push phase of the jump was also calculated. A two‐way analysis of variance showed significant interactions between the load and group effects for peak instantaneous power ( P < 0.01) and average power ( P < 0.001). Peak instantaneous power decreased significantly in sedentary individuals when moderate external loads were added. The peak instantaneous power at 0 kg was greater than that at 5 and 10 kg in the sedentary individuals. In contrast, peak instantaneous power was independent of load in the strength and power athletes. Mean power at 0 kg was significantly lower than at 5 kg in the athletes; at 0 kg it was significantly higher than at 10 kg in the sedentary males and at 5 and 10 kg in the sedentary females. In all groups, the force corresponding to peak instantaneous power increased and the velocity corresponding to peak instantaneous power decreased with external loading. The present results suggest that the effects of external loading on peak instantaneous power are not significant in strength and power athletes provided that the loads do not prevent peak velocity from being higher than the velocity that is optimal for maximal power output. 相似文献

Students’ preparedness for higher education is seen as one of the main factors affecting first-year attrition or study success.
In this paper we report on a cross-national study in which students’ preparedness for university was measured before students commenced their study at a university in New Zealand or in the Netherlands. This cross-national project provided
a unique opportunity to compare students’ perceptions of readiness for university where students are prepared for higher education
in quite different secondary school systems. Departing from a transition framework, and comparing the results in both countries
using logistic regression techniques to investigate which aspects of readiness could predict perceived preparedness, we discovered
similarities in as well as differences between students’ perceived readiness for university study. It could be argued that
differences are caused by the different educational systems at secondary level. However, overall we can conclude that, in
spite of differences between the educational systems in the two countries, many differences were not remarkable or very significant.
This has clear implications for how we view the relative importance of secondary school preparation and tertiary induction.
We can expect greater benefit from implementing first-year pedagogical practices in universities that would assist students
to develop their academic skills, than from demanding that high schools prepare students better. 相似文献

Abstract Musical education is also benefiting from the new technologies, and this article looks at how these new technologies can help the teacher and the students both in the classroom and in the workshops, which are either directed or in which students work on their own. It then looks in detail at a multi‐discipline project from the 1995‐96 multimedia workshop. 相似文献
