Comparison of the prevalence and treatment of hypertension in two populations in the United States: Masters swimmers versus the NHANES population

Abstract

This research compares the prevalence of hypertension in a group of adult masters swimmers with an age and sex matched cohort from the 2008 NHANES (National Health and Nutrition Examination Survey), used to represent the general population in the United States. Masters swimmer data were obtained from a one-time survey of all United States Masters Swimming (USMS) members. Both datasets included demographics, drug therapy, diseases and health status. Characteristics of swimming sessions as well as perceptions of impact of medications on exercise were also collected from the USMS respondents. Of 1346 completed surveys from USMS respondents, 15.8% self-identified as having hypertension while 36.2% participants in the NHANES survey suffered from hypertension (P < 0.001). The two groups were well matched for age and gender but the USMS group was primarily Caucasian, higher income, higher education, and reported higher health status. In the USMS group, not only was hypertension less prevalent but those who suffered from hypertension took fewer medications (P = 0.04) to manage their hypertension than in the NHANES group. Additionally, The USMS group suffering from hypertension considered themselves healthier (P < 0.001) than the NHANES group.     

Relationships between different instructional approaches and students' Classical Chinese reading comprehension and motivation

Previous studies comparing teacher‐centred (TC) and learner‐centred (LC) instruction have presented a mixed picture of the effectiveness of these two instructional approaches. By examining the effectiveness of different types of instruction on students' Classical Chinese (CC) reading comprehension and motivation, this study aims to contribute to instructional research by elucidating the positive and negative aspects of TC and LC instruction when they are applied in the context of teaching CC reading. A total of 454 Secondary 4 students between the ages of 15 and 17 years agreed to participate in this study on a voluntary basis. They completed a CC reading comprehension test and a questionnaire that measured their CC reading motivation and perceived CC reading instruction. Relationships between students' perceived CC reading instruction, reading motivation and reading comprehension were examined by correlation and path analyses. The findings of the correlation analyses indicated that traditional TC instruction positively and significantly correlated with students' CC reading performance and extrinsic motivation. Motivating tasks, one type of LC instruction, positively and significantly correlated with all types of motivation but did not significantly correlate with CC reading performance. In the path analysis, TC instruction exhibited a significant positive effect on reading comprehension, whereas motivating tasks continued to exhibit a significant positive effect on intrinsic motivation after the effect of the examined schools' achievement level was controlled for. The findings highlight the essential role of teachers in instructing students who are weak in particular subjects. Instead of viewing TC and LC instruction as two contradictory approaches, the findings indicate that a combined approach of TC and LC instruction can more effectively facilitate students' learning in a difficult school subject.     

Factors influencing school connectedness: Chinese adolescents’ perspectives

This study explored the concept of school connectedness and the factors that may influence its development with a sample of Chinese adolescents. Six focus groups involving 52 high school students were conducted using a set of predetermined discussion topics. Results indicated that the students fully understood the notion of school connectedness and could identify a number of key influences affecting its development. These factors could be grouped under several domains including teacher care, peer relations, broader school relationships, school disciplinary policies and practices, activities within the school’s guidance and counseling program, and opportunities for talent development. The students were also able to suggest practical strategies that schools might introduce to enhance and strengthen students’ acquisition of connectedness to school. The implications from the findings are discussed with particular reference to implementing comprehensive school guidance and counseling program in Hong Kong.     

Competition and the decline in Western television program popularity in Indonesia during the 1990s

Despite the country's population base of 240 million, Indonesian television has not been widely explored in academic and professional venues. This paper examines the impact of competition on the popularity of foreign programs in the Indonesian market during the mid-1990s. Analyzing recently released ratings data from a television ratings service, this paper suggests that competition has given rise to the popularity of local programs, while foreign program popularity has declined steeply during the same three year period. The findings also suggest that cultural proximity is a factor of the popularity of programs. By 1997, Asian programs outnumbered Western programs on the top 100 highest rated program lists in Indonesia. We explore implications of study findings for filling this void in the literature.     

澳门特区免费幼儿教育政策研究

澳门特区自2007～2008学年开始实施15年免费教育,即9年义务教育、3年高中教育和3年学前教育免费.研究者运用网络调查及访谈法,对澳门特区免费幼儿教育政策进行研究,结果发现:(1)免费幼儿教育政策只适用于6家公办幼儿园和42家加入免费教育学校系统的私立幼儿园.(2)7家未加入免费教育学校系统的私立幼儿园需缴学费、补充服务费和选择性服务费,但可获政府发放的学费津贴和书簿费.家长很满意这一政策,并表示愿意继续送孩子上收费的私立幼儿园.(3)受访园(校)长、家长及教师对澳门的免费幼儿教育政策都很满意,教师特别满意政府推出的幼儿园教师津贴.(4)免费幼儿教育政策对私立园所的影响有所不同:有些私立园所为了生存而选择加入免费教育学校系统,有些私立园所则为了校政自主而选择不加入免费教育学校系统.客观上,高收费门槛令不同阶层家庭的幼儿自然分流.     

Towards Good Practice in Community‐Based Arts Education in Hong Kong

Through the participation of local communities in the arts, Community‐Based Arts Education (CBAE) raises awareness of ecology and the environment, and also facilitates the search for and establishment of a socio‐cultural identity. It provides students with specific forms of experiential learning involving out‐of‐classroom experiences. Since 2003 the Education Bureau in Hong Kong has promoted learning arts in the community in an informal arts educational context. To suit the needs of CBAE, since 2011 the Leisure and Cultural Services Department has offered four successful community‐based arts educational schemes to local primary and secondary students. The aim of the schemes is to enrich students’ knowledge of arts and culture and strengthen their capacities to learn arts appreciation and criticism. Between 2011 and 2013, over 30,000 primary and secondary students participated in the schemes. This article reports on a study of the schemes which aimed to identify key elements of good practice in CBAE from students’ and teachers’ perspectives. In this larges‐cale study, a total of 15,430 students between Primary 1 and Secondary 6 (age 6 to 17) and 1,306 teachers who participated in the schemes were invited to take part in surveys and focus group interviews. The results show that the three central tenets of self‐determination theory, namely, competence, autonomy and relatedness, are the key elements of good practice in CBAE. It is hoped that the research findings will enrich existing knowledge of and provide a new research direction for CBAE.     

Leptotrichia hongkongensis sp. nov., a novel Leptotrichia species with the oral cavity as its natural reservoir

A straight, non-sporulating, Gram-variable bacillus (HKU24T) was recovered from the blood culture of a patient with metastatic breast carcinoma. After repeated subculturing in BACTEC Plus Anaerobic/F blood culture broth, HKU24T grew on brucella agar as non-hemolytic, pinpoint colonies after 96 h of incubation at 37 °C in an anaerobic environment and aerobic environment with 5% CO2. Growth was enhanced with a streak of Staphylococcus aureus. HKU24T was non-motile and catalase-negative, but positive for alkaline phosphatase, β-glucosidase, and α-glucosidase. It hydrolyzed phenylphosphonate and reduced resazurin. 16S rRNA, groEL, gyrB, recA, and rpoB sequencing showed that HKU24T occupies a distinct phylogenetic position among the Leptotrichia species, being most closely related to Leptotrichia trevisanii. Using HKU24T groEL, gyrB, recA, and rpoB gene-specific primers, fragments of these genes were amplified from one of 20 oral specimens. Based on phenotypic and genotypic characteristics, we propose a new species, Leptotrichia hongkongensis sp. nov., to describe this bacterium.     

Abusive parents' reports of child behavior problems: relationship to observed parent-child interactions

PURPOSE: We evaluated the hypothesis that abusive parents' reports may exaggerate rates of child behavior problems in a clinical sample. METHOD: The association between parental ratings of behavior problems and independent observations of child behaviors was examined in a sample of 205 clinic-referred families, 58 of which had a reported history of physical abuse. RESULTS: Relative to the comparison group, parents in the abuse group reported more externalizing problems in their children after controlling for parental psychopathology, and displayed more emotionally controlling and less supportive behavior during parent-child interactions. However, there was no association between abuse history and observed child behaviors during the interaction tasks. Abuse status significantly moderated the association between parent-reported externalizing behaviors and observed demanding behavior by the child; the association was significant among comparison families, but not in the abuse group families. CONCLUSIONS: Results indicate that abusive parents may over-report externalizing behavior problems in their children.
