AbstractWe examined earlier oral narrative and decoding and later reading in two samples spanning the first four years of reading instruction. The Year 1 sample (n = 44) was initially assessed after one year of instruction (M = 6; 1 years) and followed through their third year (M = 8; 1 years); the Year 2 sample (n = 34) assessed after two years of instruction (M = 7; 0 years) and followed to their fourth year (M = 9; 0 years). Oral narrative and decoding were assessed initially, oral reading, retell, and maze fluency, plus reading age, obtained at outcome. For the Year 2 sample, oral narrative and decoding contributed to oral reading and comprehension two years later. For the Year 1 sample, decoding contributed to most reading outcomes, with narrative quality uniquely predicting Year 3 retell fluency. Post-hoc exploratory analyses suggest story memory indirectly contributed to Year 3 reading via Year 2 retell. 相似文献

A universal coagulation test that reliably detects prolonged coagulation time in patients, irrespective of the anticoagulant administered, has not been available to date. An easily miniaturised, novel μ-fluidic universal coagulation test employing surface acoustic waves (SAW) is presented here. SAW was employed to instantly mix and recalcify 6 μl citrated whole blood and image correlation analysis was used to quantify clot formation kinetics. The detection of clinically relevant anticoagulant dosing with old anticoagulants (unfractionated heparin, argatroban) and new anticoagulants (dabigatran, rivaroxaban) has been tested and compared to standard plasma coagulation assays. The applicability of this novel method has been confirmed in a small patient population. Coagulation was dose-proportionally prolonged with heparin, argatroban, dabigatran, and rivaroxaban, comparable to standard tests. Aspirin and clopidogrel did not interfere with the SAW-induced clotting time (SAW-CT), whereas the strong GPIIb/IIIa-inhibitor abciximab did interfere. Preliminary clinical data prove the suitability of the SAW-CT in patients being treated with warfarin, rivaroxaban, or dabigatran. The system principally allows assessment of whole blood coagulation in humans in a point-of-care setting. This method could be used in stroke units, emergency vehicles, general and intensive care wards, as well as for laboratory and home testing of coagulation. 相似文献

Abstract In an effort to devise a simple but effective test to indicate the overall volleyball playing ability of high school boys, a thorough review of published tests was made. From this review, it was determined that there were four important aspects of a wall-volley test. Preliminary studies investigated each of these aspects and, as a result, a test similar to Brady's test was devised. Data regarding the finalized form of the test were gathered by administering it to three classes of grade 10 and 11 boys (total N=71). The test for validity produced a correlation coefficient of .767. The reliability test yielded a coefficient of .817. It was concluded that the test gave evidence of being worthy of further experimentation and use in its present form. 相似文献

The aim of the study was to examine the effects of three different training models on aerobic power and body composition in recreationally active runners. According to their preferences 54 subjects (female=?27, male?=?27) were assigned to the following groups: (a) weekend group (WE), who performed two sessions of continuous endurance training weekly, (b) after-work group (FE) who carried out four sessions of high intensity training as well as an additional endurance run and (c) STAR group (STAR), who took part in a training with exercise telemetry monitors based on the heart rate variability. Over the 12-week study period the mean training volume was approximately 2 h 15 min per week. Of the participants 47 successfully completed the training study and all 3 groups showed significantly improved aerobic power (p?<0.001); however, the FE group (d?=?1.15) showed increased VO2max superior to WE (d?=?0.48) and STAR (d?=?0.66) groups. Significant improvements in body mass (p?<?0.001), body fat (p?<?0.001) and visceral fat (p?<?0.001) were found in the WE, FE and STAR group. All groups completed the half marathon with no significant differences in performance. Based on a similar training volume, short, intensive endurance training sessions of about 30 min were found to elicit the greatest improvements of VO2max in recreationally active runners. 相似文献

Purpose: Acute benefits of aerobic exercise on executive functioning have been reported frequently under laboratory conditions. However, to date, a beneficial effect on long-term memory has been less well supported and no data are available regarding nonlaboratory conditions in young adults. The aim of the current study was to investigate acute effects of aerobic exercise on cognitive functioning in a university classroom setting. Method: Using a cross-over design, 51 participants performed a bout of moderately intense running (RUN) and read an article while seated (CON). Afterwards, they completed free-recall tests, followed by a Flanker task and an n-back task. Results: Participants in the RUN condition compared with those in the CON condition showed shorter reaction time on the inhibition task, F(1, 50) = 5.59, p = .022, η2 = .101, and recalled more words in the immediate- and delayed-recall tests, F(1, 50) = 8.40, p = .006, η2 = .144. Conclusion: The present findings suggest that a moderately intense bout of aerobic exercise benefits verbal short-term and long-term memory as well as inhibitory control among students in a classroom setting. 相似文献

Value orientations and studying in school–leisure conflict: A study with samples from five countries
Manfred Hofer Sebastian Schmid Stefan Fries Ilija Zivkovic Franziska Dietz 《Learning and individual differences》2009,19(1):101-112
The relations between students' value orientations and experiences of motivational interference during studying following conflicts between learning and leisure activities were investigated in a self-report study. Overall, 1075 adolescents, mostly from Catholic schools, in Bosnia–Herzegovina (n = 203), India (n = 200), Paraguay (n = 96), Spain (n = 442), and the US (n = 134), participated. The samples varied substantially in terms of modern and postmodern value orientations, experience of motivational interference during studying, and time invested in studying. By controlling for age, gender, and economic capital, postmodern value orientation was positively related to conflict frequency and experience of motivational interference during learning, and negatively related to time investment. For modern value orientation, the relations were almost reversed. Despite the considerable differences between the sample means, the study revealed some consistency in the relations between the variables across the samples, which indicates that most of the relations can be generalized. 相似文献

This article situates emerging three-dimensional (3D) visualization technologies in the health sciences within the broader historical context of the stereoscope. Although 3D visualization technologies enhance pedagogy and deepen student engagement, they are generally cost-prohibitive and therefore inaccessible for many institutions. In light of this issue, the authors consider the work of American gynecologist and founding member of The Johns Hopkins Hospital in Baltimore, Maryland, Dr. Howard Atwood Kelly (1858–1943). A monumental work, Kelly''s The Stereo Clinic is a multivolume publication whose focal point was the stereoscope, an image-viewing device that can be seen as a prototype for present-day 3D technologies. Each installment presents a step-by-step overview of a specific surgical procedure using a didactic narrative and corresponding stereoscopic images that illustrate the clinical practices. Significantly, Kelly understood The Stereo Clinic as an egalitarian project that provided high-quality educational resources to students and practicing physicians who did not have access to world-class clinical suites and teaching institutions. Furthermore, he viewed The Stereo Clinic as a remedy to the commonplace frustrations of medical education, such as crowded surgical suites, and the hazards of in-person observation. The Stereo Clinic is an important case study because it reveals a medical profession at the turn of the twentieth century preoccupied with 3D visualization. Inventive clinicians such as Kelly did not only advocate for this technology on the strength of its pedagogical value; they also articulated the equalitarian nature of this medium and produced 3D technology accessible to a wide audience. 相似文献
