This study investigated the relationship between both receptive and expressive prosody and each of three reading outcomes: accuracy of reading aloud words, accuracy of reading aloud nonwords, and comprehension. Participants were 63 children aged 7 to 12 years. To assess prosody, we used the Profiling Elements of Prosody in Speech Communication (PEPS-C; Peppé & McCann, 2003). Results revealed that certain subtests of the PEPS-C predicted a substantial proportion of variance across reading outcomes, even after age and segmental phonological awareness have been considered. In fact, our findings suggest that the PEPS-C compares favourably with a well-established test of segmental phonological awareness, the Comprehensive Test of Phonological Processing (CTOPP; Wagner, Torgesen, & Rashotte, 1999), in terms of its power to predict variability in children’s reading. 相似文献

This article represents two‐firsts for the feature – it is the first to report on a study outside the UK and the first to examine the health information needs of community health workers. Sonika Raj is pursuing PhD at the Centre for Public Health, Panjab University, Chandigarh, in India and she conducted her research in Chandigarh. The article outlines the important role that health workers at community level play in determining health outcomes in the developing world, including Chandigarh. It demonstrates that while those workers recognise their information needs, there are many issues affecting their ability to access health information effectively, not least their limited access to appropriate technology and training.

The purpose of this study is describe the initial feasibility, reliability, and validity of an instrument to measure physical activity in preschoolers using direct observation. The System for Observing Fitness Instruction Time for Preschoolers was developed and tested among 3- to 6-year-old children over fall 2008 for feasibility and reliability (Phase I, n=67) and in fall 2009 for concurrent validity (Phase II, n=27). Phase I showed that preschoolers spent >75% of their active time at preschool in light physical activity. The mean inter-observer agreements scores were ≥.75 for physical activity level and type. Correlation coefficients, measuring construct validity between the lesson context and physical activity types with and with the activity levels, were moderately strong. Phase II showed moderately strong correlations ranging from .50 to .54 between the System for Observing Fitness Instruction Time for Preschoolers and Actigraph accelerometers for physical activity levels. The System for Observing Fitness Instruction Time for Preschoolers shows promising initial results as a new method for measuring physical activity among preschoolers. 相似文献

ABSTRACTThis article explores the creation and transmission of second generation memories concerning the 1947 Partition of British India. The research is based on oral interviews with Punjabi families who migrated because of Partition and now live in Lahore and Delhi. It explores how Partition memories have been transmitted across generations within these families, and also examines similarities and differences between how the second generation interviewees from Delhi and Lahore remember Partition. It demonstrates that the second generation have not passively accepted everything that the first generation, or the state, has told them about Partition. The second generation's memories are also shaped by their age, nationality, religion and class, and the nature of contemporary politics. 相似文献

Serum lipid profile, apolipoprotein-B (apo-B), malondialdehyde levels(MDA) and superoxide dismutase (SOD) activity were assessed
in 12 cases of xanthelasma with and without coronary artery disease (CAD)/hypertension (HTN) and results are compared with
healthy controls. Dyslipidemia was found in 65% cases of xanthelasma as compared to 20% healthy controls. Xanthelasma patients
had significantly high malondialdehyde (MDA) levels (p<0.01) and significantly decreased (p<0.05) SOD activity as compared
to controls. Among xanthelasma patients, xanthelasma with CAD/HTN showed higher total cholesterol (236±32.7 vs 188±24.7 mg/dl),
low density lipoprotein cholesterol (157±35.5 vs 113±16 mg/dl) and Apo-B (120.5±9.4 vs 114±19.2 mg/dl) levels as compared
to xanthelasma without CAD/HTN. Results of our study indicate that xanthelasma patients with increased apo-B, MDA and decreased
SOD need cardiovascular monitoring. 相似文献

The authors analyzed data from 5,528 American Counseling Association members to examine advocacy beliefs and behavior regarding Medicare reimbursement and advocacy for counselors. Nearly half (49.3%) of the respondents had participated in one or more forms of Medicare reimbursement advocacy. Advocacy participation differed significantly by professional status. 相似文献

Osteoarthritis of knee joints is a disease of old age in both sex. It is very common after the age of 40 years in elderly
females or in postmenopausal phase of females. It is characterized by narrowing of space in joints due to inflammation. The
exact mechanism of inflammation in this disease is not yet clear. Tumor necrosis factor alpha (TNF-α) may involve in onset
of disease. The present study is being carried out in 130 female subject of age group 40–60 years suffering from osteoarthritis
of knee joints and 50 normal healthy control female subjects. A correlation is made between TNF-α and estrogen and found significant
inverse correlation (r<0.001), between TNF-α and estrogen hormone in osteoarthritic female patients as compared to normal
healthy control female group. 相似文献

Study was undertaken to assess thyroid status in hyperemesis gravidarum. 150 women pregnant with <20 weeks of gestation were
selected randomly and out of these 100 women presenting with hyperemesis formed study group while 50 normal pregnant women
served as controls. 53% of hyperemetic pregnant women were primigravidae and 82% of pregnant women presented with vomiting
at less than 12 weeks of gestation. Statistically significant, 22% of hyperemetic women had increased serum T3 levels while T4 levels were increased in 67% of women in study group as compared to 8% and 16% respectively in control group. TSH levels
were decreased in 18% of hyperemetic women as compared to 8% in control group with decrease in mean TSH level statistically
significant. 22% of hyperemetic women had electrolyte disturbances and 7% were ketonuric. In clinically euthyroid women, biochemically
altered thyroid function can attribute to vomiting and its prolongation to second trimester 相似文献
