Dear Editor, Fluoroquinolones (e.g., ciprofloxacin (CIP), enrofloxacin (ENR), and levofloxacin (LEV)) are an extensively used family of antibiotics prescribed for various infections;however, they are also increasingly used to promote livestock growth. After oral administTation, much of the parent compound is excreted via urine and feces and can enter the environment at a high concentration. These antibiotics are only partially removed in wastewater treatment plants and become a part of the environment through irrigation practices. 展开更多

Purpose: To identify the social-ecological correlates associated with fundamental movement skills at the child, family, and environment levels in young children.Methods: Preschool children from 4 Colorado Head Start/preschool centers were recruited from 2010 to 2012. Two hundred twenty-eight children(128 girls;age = 56.08 ± 4.09 months;body mass index(BMI) z-score = 0.53 ± 1.12(mean ± SD);42.1% Hispanic/Latino) and 159 families were included in the final analysis. Children’s perceived competence and fundamental movement skills were assessed via the Pictorial Scale of Perceived Competence and Social Acceptance and the Bruininks-Oseretsky Test of Motor Proficiency, 2 nd edition. Data on the number of children in the family, parent age, BMI, education, employment status, family income, perception of child coordination, and home physical activity environment were collected via a questionnaire. Linear regressions adjusted for child BMI, age, sex, and school site were performed at each level.Results: Child perceived cognitive competence was positively associated with locomotor skills(p = 0.04;adjusted R2= 0.035) and object-control skills(p = 0.003;adjusted R^2= 0.083) at the child level. Parent education, BMI, and perception of child coordination were positively associated with locomotor skills and explained 8.8% of variance, but only parent education was significant(p = 0.04) at the family level. In addition, physical environment was positively associated with locomotor skills(p = 0.02) and explained 5.5% of variance at the environment level.Conclusion: Social-ecological correlates associated with young children’s fundamental movement skills are multidimensional and differ according to skill category at the child, family, and environment levels. 展开更多

BACKGROUND Previous research suggests that parents raising a child with autism experience higher levels of psychological distress than parents of typically developing children and parents of children with other developmental disorders. Little is known, however, about the intersection between the effects of socioeconomic status(SES) on the wellbeing and sense of parental competency of parents of preschoolers with autism and how it relates to child symptom severity.AIM To examine the relationship between their child’s symptom severity, SES, as measured by neighbourhood advantage and occupational status, on the psychological wellbeing and perceived parenting competence among parents of preschoolers with autism.METHODS Parents of 117 preschool-aged children with a diagnosis of autism spectrum disorder(ASD), 107 mothers and 54 fathers, completed questionnaires about their child’s symptoms of ASD and functioning, their own perceptions of their wellbeing and parental competence on entry to an early intervention program in Sydney, Australia. Parents also provided demographic information pertaining to their occupation, level of education attained and address(postcode). All children were also assessed for their severity of symptoms using the Autism Diagnostic Observation Schedule. The Australian Socioeconomic Index of occupationalstatus as a measure of familial SES and the Index of Relative Socio-economic Advantage and Disadvantage as a measure of neighbourhood advantage were used to examine the impact of SES on parental sense of competence and wellbeing.RESULTS Compared to normative populations, both mothers and fathers in our sample reported significantly higher levels of parenting sense of efficacy but lower levels of interest in the parenting role. Mothers also displayed higher levels of satisfaction. Both mothers and fathers displayed higher levels of depression than normative populations with mothers also reporting greater levels of stress and anxiety.

This paper summarizes the challenges of identifying planetary-origin meteorites of non-igneous composition - particularly those of sedimentary origin.Evidence for putative sedimentary-origin (sedtype) meteorites and their potential parent bodies is reviewed,suggesting that the list of candidate parent bodies for sed-type meteorites includes,but is not limited to,Mars,Enceladus,Ganymede,Europa,Ceres,Vesta,and other hypothetical planets that existed between the orbits of Mars and Jupiter in the past.The extraterrestrial origin and probable parent body for sed-type meteorites should be assessed based on multiple lines of evidence,and not solely limited to tests of oxygen and noble gas isotopes,whose signatures may undergo terrestrial contamination and which may exhibit significant heterogeneity within both the Solar System and parent cosmic bodies.The observed fall of a cosmic body,evidence of hypervelocity fall,signs of impact,presence of fusion crust,melting,and/or shock deformation features in impactor fragments should be considered as priority signs of meteoritic origin. 展开更多

AIM: To investigate the behavioral and psychological disorders and the prevalence of parent ratings of attention deficit hyperactivity disorder(ADHD) symptoms among children with bilateral congenital cataracts(CCs). METHODS: This cross-sectional study investigated children with bilateral CC aged 3-8 y(CC group) using Conners’ Parent Rating Scale-48(CPRS-48) from July to December 2016. The abnormal rates of psychological symptoms in CC children and normal vision(NV) children were compared using the Chi-square test. The scores of CC children were compared with those of NV children and the Chinese urban norm using the independent samples t-test and one-sample t-test, respectively. RESULTS: A total of 262 valid questionnaires were collected. The ratio of CC children to NV children was 119:143. The overall rate of psychological symptoms in CC children was 2.28 times higher than that in NV children(46.22% vs 20.28%, Pearson’s χ2=20.062;P<0.001). CC children showed higher scores for conduct problems, learning problems, impulsiveness/hyperactivity, anxiety, and hyperactivity index than NV children and the Chinese urban norm, particularly between the ages of 3 and 5 y. Furthermore, male children aged between 6 and 8 y showed a higher impulsive/hyperactive score than females of the same age(t=6.083, P<0.001). CONCLUSION: Children with bilateral CCs have a higher rate of ADHD symptoms than children with NV. This study provides clinical evidence that screening for psychological symptoms and particularly for ADHD symptoms in children with bilateral CC are recommended for an early diagnosis and timely treatment. 展开更多

This article aims to provide an adequate interpretation for the dynamic construction of identity in private setting context in China. Naturally occurring conversations between single mother and daughter were examined by using discourse analysis. The result shows that participants in spoken interaction do not always communicate with each other through the expected/default identities. Rather they sometimes deviate from the identities that they are expected to construct. 展开更多

The objective of this study was to investigate the mediating role played by youth religiosity in the relationship between the psychosocial factors of parental attachment, peer attachment, and institutional social bonding with positive youth development (PYD). PYD was based on the 5Cs (competence, confidence, connection, character, caring &compassion)model. This study involved a cluster sampling of 677 youths in Malaysian community colleges;their ages ranged from 18 to 23 years (M = 19.47;SD = 3.59). Data were collected via self-administered questionnaires. The findings indicated that youth religiosity fully mediated the relationships of parental attachment, as well as peer attachment with PYD. Religiosity also partially mediated the relationship between institutional social bonding and PYD. Hence the findings suggest that youth religiosity, which comprises ritualistic and prosocial behaviour, contributed considerably to positive youth development. 展开更多
