Girls in Gansu, China: Expectations and aspirations for secondary schooling

Gender stratification in education is declining in China, but some recent research suggests that girls\u27 schooling is still vulnerable in poor rural areas. This chapter investigates girls\u27 educational vulnerability in Gansu, one of China\u27s poorest provinces. Specifically, it analyzes the Gansu Survey of Children and Families, a multisite survey that interviewed 2,000 rural children, along with their families, teachers, principals, and community leaders, in 2000 (when children were 9–12) and 2004 (when children were 13–16). Drawing on comparative and China-specific literature on gender and exclusion, we investigate several questions. First, do gender gaps favoring boys exist in enrollment, children\u27s educational aspirations, and parental expectations? Second, are gender gaps in enrollment, aspirations, and parental expectations worse among the poorest children and families? Third, are girls\u27 educational outcomes more sensitive to prior performance? Fourth, do characteristics of early homeroom teachers and early classroom experiences have different effects on outcomes for girls and boys? Our findings suggest that girls do not face substantially greater access barriers to basic education than do boys in much of rural Gansu

Beyond Cost: Rural Perspectives on Barriers to Education

In China, education plays an increasingly important role in the creation of wealth and poverty. In the reform era, education has become closely tied to earnings (Yang 2005; Zhang et al. 2005). Returns to education in urban China increased significantly from 1978 to 1993, though returns were still relatively low in 1993, at less than four percent per year of schooling (Zhao and Zhou 2006). More recent trend data based on National Bureau of Statistics surveys show rapid increases in economic returns to a year of education in urban China: returns nearly tripled during the period 1992 to 2003, rising from 4.0 to 11.4 percent (Zhang and Zhao 2006). In rural areas, by the year 2000, an additional year of education increased wages by 6.4 percent among those engaged in wage employment, and education is becoming the dominant factor that determines whether rural laborers are successful in finding more lucrative off-farm jobs (de Brauw et al. 2002; de Brauw and Rozelle 2007; Zhao 1997). Given the rising role of education as a determinant of economic status, those who lack access to schooling are at high risk for a life of poverty

School violence in China: A multi-level analysis of student victimization in rural middle schools

Motivation: Physical victimization at school is little studied in impoverished developing country contexts. Moreover, the role of school and classroom contexts as risk factors remains poorly understood. Purpose: The aim of the study is to investigate the prevalence of physical victimization in rural Chinese middle schools as well as the individual, teacher/classroom, and school level risk factors associated with experiencing physical victimization. Design: We use two waves of longitudinal, representative survey data to perform a multi-level logistic regression analysis of physical victimization among middle school students from 100 villages in one of China’s poorest provinces. We focus on a subset of questionnaire items that were gathered from students when the sampled children were 13-16 years old. We also utilize student data from the first wave of the survey to control for prior internalizing problems and academic achievement. Finally, we link matched data collected from principal and teacher questionnaires to examine the risk factors for physical victimization associated with students’ microclimates and the wider school environment. Findings: A substantial proportion of middle school students (40%) reported having been beaten by classmates. Elevated risk was found among males; students with prior poor performance in language; students with past internalizing problems; students of female teachers and teachers evaluated as low performing; students in disruptive classrooms; and students in classrooms undergoing mandated reforms. Implications: These findings suggest that efforts to reduce school violence should not focus on the deficits of individual students, but rather should target practices to alter the within school risk factors associated with micro-climates

Bulk Elastic Moduli and Solute Potentials in Leaves of Freshwater, Coastal, and Marine Hydrophytes. Are Marine Plants More Rigid?

Bulk modulus of elasticity (ɛ), depicting the flexibility of plant tissues, is recognized as an important component in maintaining internal water balance. Elevated ɛ and comparatively low osmotic potential (Ψπ) may work in concert to effectively maintain vital cellular water content. This concept, termed the ‘cell water conservation hypothesis’, may foster tolerance for lower soil-water potentials in plants while minimizing cell dehydration and shrinkage. Therefore, the accumulation of solutes in marine plants, causing decreases in Ψπ, play an important role in plant–water relations and likely works with higher ɛ to achieve favourable cell volumes. While it is generally held that plants residing in marine systems have higher leaf tissue ɛ, to our knowledge no study has specifically addressed this notion in aquatic and wetland plants residing in marine and freshwater systems. Therefore, we compared ɛ and Ψπ in leaf tissues of 38 freshwater, coastal and marine plant species using data collected in our laboratory, with additional values from the literature. Overall, 8 of the 10 highest ɛ values were observed in marine plants, and 20 of the lowest 25 ɛ values were recorded in freshwater plants. As expected, marine plants often had lower Ψπ, wherein the majority of marine plants were below −1.0 MPa and the majority of freshwater plants were above −1.0 MPa. While there were no differences among habitat type and symplastic water content (θsym), we did observe higher θsym in shrubs when compared with graminoids, and believe that the comparatively low θsym observed in aquatic grasses may be attributed to their tendency to develop aerenchyma that hold apoplastic water. These results, with few exceptions, support the premise that leaf tissues of plants acclimated to marine environments tend to have higher ɛ and lower Ψπ, and agree with the general tenets of the cell water conservation hypothesis

Workplace policies and practices promoting physical activity across England: What is commonly used and what works?

Purpose. Many adults fail to achieve sufficient moderate-to-vigorous physical activity (MVPA). Understanding how workplaces most effectively promote physical activity can benefit public health. Design/methodology/approach. Data were collected via two online surveys. Firstly, 3,360 adults employed at 308 workplaces across England self-reported their MVPA, activity status at work and frequency of journeys made through active commuting. From this sample, 588 participants reported on the policies and practices used in their workplace to promote physical activity. Factor and cluster analysis identified common practice. Regression models examined the association between the workplace factors and engagement in physical activity behaviours. Findings. Five factors emerged: targeting active travel, information about physical activity outside the workplace, facilities and onsite opportunities, sedentary behaviour, and information about physical activity within the workplace. Further, five clusters were identified to illustrate how the factors are typically being utilised by workplaces across England. Commonly used practices related to promoting active travel, reducing sedentary behaviour and the provision of information but these practices were not associated with meeting MVPA guidelines. The provision of facilities and onsite exercise classes was associated with the most positive physical activity behaviour outcomes; however, these structures were rarely evident in workplaces. Originality/value. Previous research has identified a number of efficacious actions for promoting physical activity in the workplace, however, research investigating which of these are likely to be acceptable to worksites is limited. The present study is the first to combine these two important aspects. Five common profiles of promoting physical activity in worksites across England were identified and related to physical activity outcomes. Guidance is given to workplace managers to enable them to maximise the resources they have for the greatest gains in employee health. Where feasible, facilities and classes should be provided to achieve the most positive outcomes

Prevalence of iron deficiency in 62,685 women of seven race/ethnicity groups: The HEIRS Study.

BackgroundFew cross-sectional studies report iron deficiency (ID) prevalence in women of different race/ethnicity and ages in US or Canada.Materials and methodsWe evaluated screening observations on women who participated between 2001-2003 in a cross-sectional, primary care-based sample of adults ages ≥25 y whose observations were complete: race/ethnicity; age; transferrin saturation; serum ferritin; and HFE p.C282Y and p.H63D alleles. We defined ID using a stringent criterion: combined transferrin saturation <10% and serum ferritin <33.7 pmol/L (<15 μg/L). We compared ID prevalence in women of different race/ethnicity subgrouped by age and determined associations of p.C282Y and p.H63D to ID overall, and to ID in women ages 25-44 y with or without self-reported pregnancy.ResultsThese 62,685 women included 27,079 whites, 17,272 blacks, 8,566 Hispanics, 7,615 Asians, 449 Pacific Islanders, 441 Native Americans, and 1,263 participants of other race/ethnicity. Proportions of women with ID were higher in Hispanics and blacks than whites and Asians. Prevalence of ID was significantly greater in women ages 25-54 y of all race/ethnicity groups than women ages ≥55 y of corresponding race/ethnicity. In women ages ≥55 y, ID prevalence did not differ significantly across race/ethnicity. p.C282Y and p.H63D prevalence did not differ significantly in women with or without ID, regardless of race/ethnicity, age subgroup, or pregnancy.ConclusionsID prevalence was greater in Hispanic and black than white and Asian women ages 25-54 y. p.C282Y and p.H63D prevalence did not differ significantly in women with or without ID, regardless of race/ethnicity, age subgroup, or pregnancy

Kinetically controlled coassembly of multichromophoric peptide hydrogelators and the impacts on energy transport

We report a peptide-based multichromophoric hydrogelator system, wherein π-electron units with different inherent spectral energies are spatially controlled within peptidic 1-D nanostructures to create localized energy gradients in aqueous environments. This is accomplished by mixing different π-conjugated peptides prior to initiating self-assembly through solution acidification. We can vary the kinetics of the assembly and the degree of self-sorting through the choice of the assembly trigger, which changes the kinetics of acidification. The hydrolysis of glucono-δ-lactone (GdL) provides a slow pH drop that allows for stepwise triggering of peptide components into essentially self-sorted nanostructures based on subtle pKa differences, whereas HCl addition leads to a rapid formation of mixed components within a nanostructure. Using 1H NMR spectroscopy and fiber X-ray diffraction, we determine the conditions and peptide mixtures that favor self-sorting or intimate comixing. Photophysical investigations in the solution phase provide insight into the correlation of energy-transport processes occurring within the assemblies to the structural organization of the π-systems
