Characteristic Functions and the Central Limit Theorem
2020
The main goal of this chapter is the central limit theorem (CLT) for sums of independent random variables (Theorem 15.37) and for independent arrays of random variables (Lindeberg–Feller theorem, Theorem 15.43). For the latter, we prove only that one of the two implications (Lindeberg’s theorem) that is of interest in the applications.
Bio-vaterite formation by glycoproteins from freshwater pearls
2010
Abstract A 48 kDa acidic and putative calcium-binding glycoprotein was isolated from pearls of the freshwater mussel Hyriopsis cumingii . This protein was compared with a related 46 kDa polypeptide, obtained from the nacreous shell of the same species. Separation by two-dimensional gel electrophoresis revealed that the difference in molecular weight is due to the higher extent of glycosylation of the 48 kDa protein existing in pearls. Evidence is presented that the sugar moieties of the protein contribute to crystal growth, starting with the nucleation step. In in vitro precipitation experiments, the 48 kDa glycoprotein of pearls directed the formation of round-shaped vaterite crystals whil…
Effects of school-based interventions on motivation towards physical activity in children and adolescents: A systematic review and meta-analysis
2020
Introduction Assuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents. Methods A comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation…

Tween Girls' Perception of Gender Roles and Gender Identities
2011
PurposeThe present study aims to examine girls' perception of gender roles and gender identities in Hong Kong.Design/methodology/approachA total of 16 girls aged 10 to 12 were asked to take pictures from the media that could illustrate “what girls or women should or should not be; and what girls or women should or should not do”. Qualitative interviews were conducted.FindingsAnalysis of interviews and images captured found that tween girls' perceived gender roles for females were based on a mixture of traditional and contemporary role models. Girls in Hong Kong demonstrated conservatism in sexuality. Sexy outlook and pre‐marital sexual relations were considered inappropriate. Tween girls sh…
The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…
2019
The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…
Stoïlow’s theorem revisited
2020
Stoilow's theorem from 1928 states that a continuous, open, and light map between surfaces is a discrete map with a discrete branch set. This result implies that such maps between orientable surfaces are locally modeled by power maps z -> z(k) and admit a holomorphic factorization. The purpose of this expository article is to give a proof of this classical theorem having readers in mind that are interested in continuous, open and discrete maps. (C) 2019 Elsevier GmbH.

Relationships Between Childhood Health Experience and Depression Among Older People: Evidence From China
2021
The assessment of childhood health experience helps to identify the risk of depression among older people. Poor childhood experience is generally associated with depression in adulthood. However, whether such association can be extended to older people’ life remains unclear. The history of parental mental health was obtained from 2014 CHARLS Wave 3 (Life History Survey) data while other data from 2011 CHARLS Wave 1 baseline data. The study involves 4,306 respondents. The depression was assessed by the Chinese version of Center for Epidemiologic Studies Depression scales (CES-D) using logistic regression model. More than 40% of older people suffered from depression, 25% of whom experienced p…
The significance of student voice: female students’ interpretations of failure in Tanzanian secondary education
2014
Abstract: In Tanzania, the national examinations are used as the primary tools for selection and transition from lower to upper secondary education. Female students are more likely to fail in the national exams and to drop out from education. This article examines the perspectives of female students concerning their advancement in secondary education. Two sets of qualitative data, responses to a research questionnaire from 100 female lower secondary school students and follow-up interviews with seven mature students enrolled in a non-formal school who had failed in the national examinations, were analysed to identify critical issues influencing the educational advancement of female students…
