Reading together draws much attention as a societal concern for children not only to yield emotional reaction but also to gradually advance intellectual thinking. We here aim to build a new environment, in which children’s browsing and reading of picture books together with families and/or friends is steadily enhanced, by installing the BrowsReader in the children’s room of a public library or a kindergarten. The original BrowsReader was a system to assist children in finding and reading picture books. The children, by gathering around the BrowsReader, can browse picture books and then choose and read a book by flipping pages on it. After reproducing each printed, digitized or web picture book as a surrogate picture book consisting of the front-cover image followed by the page images, we first introduce two basic notions: (i) an abstracted bookshelf, which presents the front-cover images of the surrogate picture books in the form where all are linearly arranged, with some of the images bundled in places, and (ii) a unified view, which presents each page of any surrogate picture book in a form that seems like a printed picture book’s page. We then specify, based on these notions, the improved version of the BrowsReader which can be installed in each children’s room so that children together with families and/or friends can easily browse a large number of surrogate picture books as if they are browsing in the physical bookshelves of the children’s room, and can read a wide variety of surrogate picture books as if they are reading ordinary printed picture books on a table. The improvement was carried out in a step by step process based on feedback and results from case studies, and its effects were clarified by seeing whether, in a new environment, the children’s activity in browsing/reading together were steadily enhanced when using the BrowsReader. 相似文献

This paper discusses formation problem for robotic swarms when multiple robotic swarms cross one another's path. To realize the crossing motion, collision avoidance between agents is an important issue, with the potential to cause a general mix-up of formation during the crossing motion. To realize an orderly and well-organized crossing motion with the least mix-up, as well as collision avoidance, we propose a distributed controller. This well-organized crossing motion can realize visually appealing and highly entertaining robotic mass games. This paper proposes a distributed controller using the gradient of the cost functions about the formation maintenance, collision avoidance, and tracking to the desired trajectory. We then prove that we can achieve a well-organized crossing motion of multiple robotic swarms under several assumptions. Finally, experimental and numerical simulations are carried out to investigate whether the well-organized crossing motion can be achieved. 相似文献

This study examined the influence of critical reading orientation on use of external strategies such as note‐taking and underlining while reading an expository text. In two experiments, undergraduate students were asked either to review an article on a linguistic policy (critical reading) or to summarise it (less‐critical reading). Experiment 1 indicated that, when permitted to do so, the majority of students used note‐taking and/or underlining strategies for critical reading as well as for less‐critical reading. In Experiment 2, an analysis of think‐aloud protocols, notes, and underlines revealed that critical readers produced more critical notes/underlines and fewer summary notes than did less‐critical readers. Also, critical readers substantially increased their production of critical notes/underlines over the course of reading and decreased highlightings, whereas less‐critical readers increased summary notes and decreased highlightings. 相似文献

学生资助和高等教育机会均等(续2)——对中日美3国的比较分析 总被引：4，自引：0，他引：4
本期主要讨论日本、中国的学费和学生资助状况。在日本,学费上涨很快,但是学生资助制度没有及时得到完善。国家财政提供的资助主要通过日本学生资助机构办理。该资助属贷款而不是赠予,学生在毕业后必须偿还。多数私立大学虽设立了具有其特色的奖助贷学金,但获资助学生非常少。即便是日本国立大学的学生,其教育费负担也很重。在中国,公立大学的学费飞速上涨。虽然中国的学生资助类型多样,但是赠予型多用于奖优,助贫主要靠贷款,借贷学生的偿还压力很大。中日两国都有待于进一步改善其教育机会均等化政策。 相似文献

上期讨论了相关理论并简单介绍了高学费、高资助政策。本期介绍对高学费、高资助政策的各种批判意见和各国的学生资助概况,考察了学生资助制度比较完善的美国的状况,包括其历史、现状、社会背景以及存在的问题等。结果显示美国的财政资助卓有成效,但也存在学生负债过重和不还敖现象,还有学生资助基准的变化使教育机会均等面临危机。 相似文献

Objective
The ideal medication for the treatment of acid-related diseases, e.g., peptic ulcers, stress-related gastric bleeding, functional dyspepsia, and gastroesophageal reflux disease, should have a rapid onset of action to promote hemostasis and relieve the symptoms. The aim of our study was to investigate the inhibitory effects on gastric acid secretion of a single oral administration of a proton pump inhibitor, omeprazole 20 mg, and an H2-receptor antagonist, roxatidine 75 mg.Methods
Ten Helicobacter pylori-negative male subjects participated in this randomized, two-way crossover study. Intragastric pH was monitored continuously for 6 h after single oral administration of omeprazole 20 mg and roxatidine 75 mg. Each administration was separated by a 7-d washout period.Results
During the 6-h study period, the average pH after administration of roxatidine was higher than that after administration of omeprazole (median: 4.45 vs. 2.65; P=0.0367). Also during the 6-h study period, a longer duration of maintenance at pH above 2, 5, and 6 was observed after administration of roxatidine 75 mg than after administration of omeprazole 20 mg (median: 90.6% vs. 55.2%, P=0.0284; 43.7% vs. 10.6%, P=0.0125; 40.3% vs. 3.3%, P=0.0125; respectively).Conclusions
In Helicobacter pylori-negative healthy male subjects, oral administration of roxatidine 75 mg increased the intragastric pH more rapidly than that of omeprazole 20 mg. 相似文献28.

This study investigated students’ spontaneous use of source information for the resolution of conflicts between texts. One-hundred fifty-four undergraduate students read two conflicting explanations concerning the relationship between blood type and personality under two conditions: either one explanation with a higher credibility source and the opposite explanation with a lower credibility source or the same two explanations but with the sources interchanged. Afterwards, students wrote their opinions about the controversial issue. In their opinion essays, students were more likely to resolve the conflicts between the two explanations by affirming the one from the higher credible source and/or negating the opposite one from the lower credible source, though source manipulation had a small and partial effect on intertextual conflict resolution compared with the perceived quality of each explanation and prior attitudes. However, students’ attention to source information during reading and their use of the information for justifying their intertextual conflict resolution were limited. These results suggest that undergraduate students are capable of, but not good at, using source information for intertextual conflict resolution. 相似文献

Flight dynamics of the screw kick in rugby 总被引：1，自引：1，他引：0
This paper describes the aerodynamic forces and the flight trajectory for the screw (spiral) kick in rugby. The screw kick
is defined as that which causes the ball to spin on its longitudinal axis. The aerodynamic forces acting on a rugby ball spinning
on its longitudinal axis were measured in a wind tunnel using a six-component strut type balance. It was found that the drag,
the lift and the pitching moment depend on the angle of attack, while the side force (Magnus force) depends on both the spin
rate and the angle of attack in the range where the wind speed lies between 15 and 30 m s-1 and the spin rate is between 1 and 10 revolutions per second. Moreover, the flight trajectory was obtained by integrating
the full nonlinear six degrees of freedom equations of motion on the basis of aerodynamic data. In a simulation, a ball spinning
on its longitudinal axis tended to hook toward or away from the touchline even if the velocity and angular velocity vectors
were parallel to the touchline. The direction of the hook depends on the direction of the angular velocity vector. The initial
direction of the hook depends on the relationship between the flight path angle and the pitch angle as well as the direction
of the angular velocity vector. 相似文献
