This study examined a method of predicting body density based on hydrostatic weighing without head submersion (HWwithoutHS). Donnelly and Sintek (1984) developed a method to predict body density based on hydrostatic weight without head submersion. This method predicts the difference (D) between HWwithoutHS and hydrostatic weight with head submersion (HWwithHS) from anthropometric variables (head length and head width), and then calculates body density using D as a correction factor. We developed several prediction equations to estimate D based on head anthropometry and differences between the sexes, and compared their prediction accuracy with Donnelly and Sintek's equation. Thirty-two males and 32 females aged 17-26 years participated in the study. Multiple linear regression analysis was performed to obtain the prediction equations, and the systematic errors of their predictions were assessed by Bland-Altman plots. The best prediction equations obtained were: Males: D(g) = -164.12X1 - 125.81X2 - 111.03X3 + 100.66X4 + 6488.63, where X1 = head length (cm), X2 = head circumference (cm), X3 = head breadth (cm), X4 = head thickness (cm) (R = 0.858, R2 = 0.737, adjusted R2 = 0.687, standard error of the estimate = 224.1); Females: D(g) = -156.03X1 - 14.03X2 - 38.45X3 - 8.87X4 + 7852.45, where X1 = head circumference (cm), X2 = body mass (g), X3 = head length (cm), X4 = height (cm) (R = 0.913, R2 = 0.833, adjusted R2 = 0.808, standard error of the estimate = 137.7). The effective predictors in these prediction equations differed from those of Donnelly and Sintek's equation, and head circumference and head length were included in both equations. The prediction accuracy was improved by statistically selecting effective predictors. Since we did not assess cross-validity, the equations cannot be used to generalize to other populations, and further investigation is required. 相似文献

全球化时代的日本学校教育改革--危机与改革的构想 总被引:12,自引:0,他引:12
全球化引发了产业社会向后产业社会的转型,以产业社会为基础建立起来的日本现代学校教育体制面临着严峻的挑战。在官僚主义统治和新自由主义政策把持下的日本教育改革,以一种新的竞争态势使教育的公共性与民主性陷入危机。日本的教育改革不是仅仅依靠新自由主义与新保守主义的政策来推进,更多地是依靠社会民主主义的政策,将学校改革作为一场“静悄悄的革命”而不断发展。因此,日本的教育改革要批判地吸收新保守主义与新自由主义的主张,提倡以“民主主义”与“公共性”原理为基础,构建“学习共同体”的学校改革理念,并通过建立学校之间的联合与教师之间的合作关系而有效地组织并支持改革。 相似文献

This study reveals the school culture and the teachers’ professional development activities in a Japanese high school learning environment. Furthermore, it documents the relationships among the context, teachers’ beliefs, practices, and interactions. Using multiple data sources including interviews, observations, and documents of teachers from an English department, this yearlong study revealed these English as a Foreign Language teachers lacked many teacher learning opportunities in their context. The study revealed that teacher collaboration only reinforced existing practices, eroding teachers’ motivation to learn to teach in this specific context. The study provides evidence to teacher educators about inservice teachers and their learning environment and the significance of the relationships between the two entities. 相似文献

This article discusses the validity of the incorporation of online communication in language education classes as a practice free of power politics. By examining blog activities in an advanced‐level Japanese‐as‐a‐Foreign‐Language classroom at a university in the USA, we show that the blog’s postings and readers’ comments evoke certain modes of governmentality – practices that shape one’s conduct – and define the space of a particular blog. This article illustrates two kinds of space created in blogs: that of language education in which ‘native speakers’ dominate ‘non‐native speakers’; and that of information exchange with less fixed relations of dominance, although participants’ behavior is regulated nonetheless. We suggest involving students in analyzing blog comments so that they can understand, and respond to, how the mode of governmentality works outside the classroom and how to transform relations of dominance that manifest themselves in online spaces. 相似文献

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

ABSTRACTUnderstanding active sport tourists’ profiles and nurturing their destination loyalty are important considerations in the tourism market. Loyal tourists are valuable because they tend to revisit a focal destination and elicit positive word-of-mouth. Focusing on a snow-based active sport tourism context, this study was conducted to examine (1) the usefulness of experience-use history (EUH) as a segmentation tool and (2) the relationship between perceived value factors (i.e. quality, emotional response, monetary price, behavioral price, and destination reputation) and destination loyalty in each EUH group. Data were collected from the Niseko ski resort in Japan (N?=?328). Based on the EUH variables (i.e. length and frequency of snow-based sport participation), participants were categorized into four segments (i.e. novice, short-active, long-inactive, and expert). The results showed significant differences among EUH groups in terms of their socio-demographics (e.g. gender, age, and income). A series of regression analyses also showed that each segment’s destination loyalty was uniquely enhanced by perceived value factors. Specifically, perceived quality was a significant antecedent of destination loyalty for sport tourists in the novice group. For those in the short-active, long-inactive, and expert groups, perceived emotional response significantly predicted destination loyalty. Perceived reputation of the destination was also important to enhance destination loyalty for the short-active group whereas perceived monetary price was positively associated with the long-inactive group’s destination loyalty. Marketing managers in snow-based sport tourism destinations can utilize the findings to increase the loyalty of active sport tourists, which will improve their competitiveness in the marketplace. 相似文献

ABSTRACT Understanding the different experiences between local and non-local participants may help event organizers implement diverse marketing strategies for each segment, which could efficiently improve participants’ experiences of the event. However, little research has compared the experiences between local and non-local participants in sport event settings. This study compares the differences between local and non-local participants in their perceived service quality of a triathlon event, examines the relationships among service quality, satisfaction, and behavioral intention, and explores the role of participants’ residence status in these relationships. Data were collected from participants (N?=?289) in a triathlon event held in Japan. The results indicate that local participants evaluated all service quality dimensions more positively than non-local participants. The course, ambience, achievement, and escape had positive effects on satisfaction, satisfaction had an extensively positive effect on behavioral intention, and the effect of escape on satisfaction differed between local and non-local participants. Our findings identify how local and non-local participants evaluate their event experiences differently and provide practical implications for event organizers. 相似文献
