This paper asks what is necessary in a theory of science adequate to the task of empowering philosophers of science to participate
in public debate about science in a social context. It is argued that an adequate theory of science must be capable of theorizing
the role of values and motives in science and that it must take seriously the irreducibly social nature of scientific knowledge.

Although measures of student ratings of instruction have been developed and examined empirically, students' attitudes about the utility of these ratings have yet to be meaningfully quantified. Using survey responses from 1229 students at a major Canadian university, we developed a psychometrically sound measure of the usefulness of student ratings. A principal components analysis with oblique rotation was conducted and three factors (Instructor characteristics, Course characteristics and Instructor's relative ranking) were obtained that explained 64% of the variance in six iterations. The usefulness of these three types of ratings information differs according to several student and course characteristics. The present results provide evidence for both reliability and validity of the instrument as an indicator of the utility of teaching evaluation for students. 相似文献

Robert Louis Stevenson’s poem “Foreign Children,” Rudyard Kipling’s poem “We and They,” and Frances Temple’s youth novel The Beduins’ Gazelle are the texts submitted to detailed analysis in this article, which examines cross-cultural perspectives in relation to imperial
and post-imperial social contexts. Stevenson is shown to portray the basic structure of an imperial cross-cultural perspective,
which Kipling problematizes and calls into question. Analysis of Temple reveals her awareness of the problems and limitations
that inhere in an imperial perspective and shows that her work presents innovative, contemporary approaches to the representation
of cross-cultural perspectives. 相似文献

Abstract It has been suggested in the lay literature that static stretching and/or warm-up will prevent the occurrence of Delayed-Onset Muscle Soreness (DOMS). The primary purpose of this study was to determine the effects of static stretching and!or warm-up on the level of pain associated with DOMS. Sixty-two healthy male and female volunteers were randomly assigned to four groups: (a) subjects who statically stretched the quadriceps muscle group before a step, (b) subjects who only performed a stepping warm-up, (c) subjects who both stretched and performed a stepping warm-up prior to a step test, and (d) subjects who only performed a step test. The step test (Asmussen, 1956) required subjects to do concentric work with their right leg and eccentric work with their left leg to voluntary exhaustion. Subjects rated their muscle soreness on a ratio scale from zero to six at 24-hour intervals for 5 days following the step test. A 4×2×2 ANOVA with repeated measures on legs and Duncan's New Multiple Range post-hoc test found no difference in peak muscle soreness among the groups doing the step test or for gender (p > .05). There was the expected significant difference in peak muscle soreness between eccentrically and concentrically worked legs, with the eccentrically worked leg experiencing greater muscle soreness. We concluded that static stretching and!or warm-up does not prevent DOMS resulting from exhaustive exercise. 相似文献

Abstract The purpose of this study was to compare three methods of relieving fatigue between bouts of strenuous exercise—rest, abdominal cold packs, and cold showers. Fifteen subjects were used in the study; each subject participated in each of the three treatments, making a total of 45 measurements. The subjects ran on a treadmill which was set at 8 mph with a 10 percent elevation, until their pulse rates reached 180 beats per minute. One of the three treatments was then applied for 10 min., after which the subjects engaged in a second treadmill run until heart rates reached 180 beats per minute. The time of the second treadmill run was the main criterion measure. A complete randomized block design was used to test the differences among the three treatments for statistical significance. The Newman-Keuls sequential range test was employed to test differences between all possible pairs of treatment. Abdominal cold packs proved to be the most effective treatment, with the cold shower second and rest third. 相似文献

Abstract This study was designed to investigate the relationships between three measures of body image and two measures of physiological performance. The Fisher-Cleveland Barrier Index, the Secord Homonym Test, and the Body Cathexis Questionnaire were correlated with dominant hand grip strength and the Michael-Gallon revision of the Harvard Step Test. Pearson's r was employed to determine the degree of relationship. Fifty males selected at random from general education classes at San Fernando Valley State College constituted the research sample. Of the six possible pairings only one reached statistical significance: the Homonym Test and grip strength (r = .33 at .05 level). It was concluded that a general relationship does not seem to exist between the measures of body image and physiological performance utilized in this study. These and other findings led the authors to re-examine several questions concerning the nature of body image phenomena. 相似文献

Abstract The aim of this study was to objectively quantify ratings of perceived enjoyment using the Physical Activity Enjoyment Scale following high-intensity interval running versus moderate-intensity continuous running. Eight recreationally active men performed two running protocols consisting of high-intensity interval running (6×3 min at 90% [Vdot]O2max interspersed with 6×3 min active recovery at 50% [Vdot]O2max with a 7-min warm-up and cool down at 70% [Vdot]O2max) or 50 min moderate-intensity continuous running at 70% [Vdot]O2max. Ratings of perceived enjoyment after exercise were higher (P < 0.05) following interval running compared with continuous running (88 ± 6 vs. 61 ± 12) despite higher (P < 0.05) ratings of perceived exertion (14 ± 1 vs. 13 ± 1). There was no difference (P < 0.05) in average heart rate (88 ± 3 vs. 87 ± 3% maximum heart rate), average [Vdot]O2 (71 ± 6 vs. 73 ± 4%[Vdot]O2max), total [Vdot]O2 (162 ± 16 vs. 166 ± 27 L) or energy expenditure (811 ± 83 vs. 832 ± 136 kcal) between protocols. The greater enjoyment associated with high-intensity interval running may be relevant for improving exercise adherence, since running is a low-cost exercise intervention requiring no exercise equipment and similar relative exercise intensities have previously induced health benefits in patient populations. 相似文献

Abstract This aim of this study was to analyse the nature of movement variability and to assess whether entropy measures may represent a valuable synthetic index of neuromuscular organization. The regularity of kinematic/kinetic time series during race walking, the changes in the structure of intra-individual variability over the test session, and the influence of athletic skill in (inter)national rank athletes were investigated. Motion analysis techniques were used. Sample entropy (SampEn) was adopted to examine fluctuations in lower limb angles and ground reaction forces. The regularity of both original and surrogate time series was assessed and compared, by estimating SampEn, to verify the presence of non-linear features in movement variability. SampEn was statistically lower in the original data than in surrogates. In contrast, the regularity of time series did not change significantly throughout the subsequent intra-individual repetitions. Hip and ankle joint angles and vertical ground reaction force manifested increased entropy for skilled athletes. Results suggest that race walking variability was not only the product of random noise but also contained information about the inherent propriety of the neuro-musculo-skeletal system. Furthermore, they provide some indications about neuromuscular control of the lower limb joints during race walking gait, and about the differences between more and less skilled individuals. 相似文献
