The aim of this study was to determine pedometry steps per minute (SPM) cutscores that accurately quantify physical activity (PA) time in first- through fourth-grade physical education. A total of 257 participants were grouped in two data pools, first- and second-grade (n = 126), and third- and fourth-grade (n = 131). Systematic observation was the PA criterion instrument and pedometry was the predictor instrument. Correlations between physical activity measures were strong (r = .82-.89, p < .01). Ten min of PA and 33.33% of the lesson time engaged in PA within a 30-min class can be quantified by 61-63 SPM for first- and second-grade, and 58-61 SPM for third- and fourth-grade. IN CONCOLUSION: (a) SPM values were a valid indicator of students achieving or not achieving PA criteria, and (b) pedometry is a valid and practical tool for physical activity surveillance within physical education. 相似文献

Third- and fourth-grade students in two separate classrooms--one a classroom with only hearing students and the other a coenrolled classroom with hearing, hard of hearing, and deaf students--were assessed to determine friendship patterns, attitudes, beliefs, and perceptions about sign language and deafness. Sociograms, interviews, and videotape analysis of the students' responses were done. Results suggest that hearing students in the coenrolled classroom had better sign language skills, a more positive attitude toward deafness, and an improved awareness of certain aspects of hearing loss (such as speech and amplification). Deaf and hard of hearing students' social acceptance was similar to that of their hearing peers. 相似文献

The practice of abandoning newborns shortly after birth has always existed. Occurring in primitive and contemporary societies, the motivations for newborn abandonment are varied and dependent upon the social norms of a specific geographic region at a given point in time. Because the desire to abandon an infant has had no support system in American society, such unwanted infants have been abandoned in a manner leading to their deaths. In response, many states have passed safe-haven legislation to save the lives of unwanted newborns. The laws typically specify a mother's ability to "abandon" her child to a medical service provider. However, judgmental attitudes and a lack of accurate information may impede a health care provider's ability to carry out a safe-haven law. The study described here examines a sample of nurses in a state with a safe-haven law. The study revealed no significant correlation between a nurse's knowledge, attitude, and self-perception of preparedness to manage a newborn abandonment event. owever, the outcomes highlight the negative attitudes and lack of knowledge many nurses possess regarding newborn abandonment and the women who commit this act. Educational programs for all health care providers and the community are essential to the efficacy of the legislation that currently exists. Continued multidisciplinary strategizing and general awareness are needed to serve as catalysts to build supports for unwanted newborns and their safe assimilation into the community. 相似文献

Deaf education teacher preparation programs must prepare teachers to staff an increasing number of oral programs. A survey was conducted to determine which competencies administrators of deaf education programs rate as important for teachers in oral programs and to compare ratings of these competencies by oral school administrators to ratings made by administrators of comprehensive deaf and hard of hearing programs. Between the two groups of administrators, six areas of agreement about competencies were found. There were notable differences in the range of ratings between the two groups. These differences were attributed to the roles teachers assume in the two types of programs and the focus of instruction in each type of program. 相似文献

Body donation is important for medical education and academic research. However, it is relatively rare in Hong Kong when compared with many Western countries. Comprehensive research has been performed on the motivation for body donation in Western countries; however, there is still insufficient research on body donation in Hong Kong to provide information on how to increase the body‐donation rate. To understand the factors involved in the decision to donate one's body, the authors interviewed a registered donor and the daughter of another donor in Hong Kong. The authors interpreted the information collected in light of the available published reports, which mostly focus on body donation in Western countries. Despite the consistency of some demographic factors and motivations between the participants in our study and those investigated in the published reports from Western countries, there are differences in education level and socioeconomic status between the donors in our study and those from Western studies. The authors also suggest that Confucianism and Buddhism in Chinese culture may motivate potential body donors in Hong Kong. Other important factors that influence the body‐donation decision may include family members' body donation, registration as organ donors, and good doctor–patient relationships. Although case report studies have their limitations, this study allows us to explore the complexity of events and establish the interconnectivity of factors involved in body donation, which could not be achieved in previous survey‐based studies. © 2012 American Association of Anatomists. 相似文献

10岁独生子房间的地板上堆满了连环画,我差一点摔倒。我知道有些事情是必须要做了。当然,不再是威胁和最后通牒,那些都只能起暂时的作用,不用过等长时间,连环画又完满地皆是的。思考再三,我想到了一个好主意:应该使一切都规范起来。于是,我买了一些彩色的文件夹和塑料箱子,和儿子一起把一切零乱的东西摆放整齐。从此,我不再对他唠叨,他的房间也不再杂乱无章。事实上,忙碌的父母们经常在孩子面前扮演教练官的角色,而这样不仅毫无效果,反而会使孩子与父母产生对立的情绪,双方都很不愉快。那么。当我们想要孩子做某件事时应该… 相似文献

We report an important observation that the surface conductivity of antibody layer immobilized on polylysine-coated glass
substrate decreases upon the formation of complex with their specific antigens. This change in conductivity has been observed
for both monoclonal and polyclonal antibodies. The conductance of monoclonal mouse IgG immobilized on polylysine-coated glass
substrate changed from 1.02×10−8 Ω−1 to 1.41×10−11 Ω−1 at 10 V when complex is formed due to the specific biomolecular interactions with rabbit anti-mouse IgG F(ab′)2. Similar behavior was observed when the same set up was tested in two clinical assays: (1) anti-Leishmania antigen polyclonal
antibodies taken from Kala Azar positive patient serum interacting with Leishmania promastigote antigen, and (2) anti-p21
polyclonal antibodies interacting with p21 antigen. The proposed concept can represent a new immunodiagnostic technique and
may have wide ranging applications in biosensors and nanobiotechnology too. 相似文献

Two sulfonylurea herbicides, metsulfuron methyl (Ally 20 WP) and chlorimuron ethyl (Classic 25 WP) were evaluated for their dissipation bchaviour in alluvial, coastal saline and laterite soils under laboratory incubated condition at 60% water holding capacity of soils and 30 ℃ temperature was maintained. In field study herbicides were applied twice for the control of grasses, annual and perennials broad leaves weeds and sedges in rice, wheat and soybean to find out the residual fate of both the herbicides on different matrices of respective crops after harvest. Extraction and clean up methodologies for the herbicides were standardized and subsequently analyzed by HPLC. The study revealed that the half-lives of metsulfuron methyl and chlorimuron ethyl ranged from 10.75 to 13.94 d irrespective of soils and doses applied. Field trials with rice, wheat and soybean also revealed that these two herbicides could safely be recommended for application as no residues were detected in the harvest samples. 相似文献
