大学生学习性投入与在校满意度、向学/厌学的关系

目的:探讨大学生学习性投入的基本情况及其与在校满意度、向学/厌学之间的关系。方法:采用"中国大学生学习与发展追踪研究"(China College Student Survey,CCSS)的调查工具,即汉化后的大学生学习性投入调查问卷(NSSE-China),对某新建本科院校1446名大学生进行调查。结果:(1)不同性别和年级的学生在学习性投入上存在显著性差异;(2)学习性投入各个维度与在校满意度、向学/厌学均呈现显著正相关(P0.01)。其中校园环境支持度与在校满意度、向学/厌学关系最为密切(r=0.48,0.53;P0.01);(3)学习性投入各个维度对在校满意度、向学/厌学均有显著的正向预测作用,其中校园环境支持度是预测在校满意度和向学/厌学最有力的因子(R2=0.23,0.28)。结论:学校可以通过提高校园环境支持度来有效提高学生的在校满意度和向学倾向。     

Bagasse as a carbon structure with high sulfur content for lithium–sulfur batteries

A bagasse-based 3D carbon matrix (BC) with high specific surface area and high conductivity was obtained by carbonization and pore-forming processes with bagasse as the carbon precursor and K₂FeO₄ as the pore-former. The microporous structure and nitrogenous functional groups were determined in the prepared carbon matrix, which could allow high sulfur loading and improve the polysulfide absorption capacity during cycling. After sulfur infusion, the S/BC composite with 68.8% sulfur content was obtained. The lithium–sulfur (Li–S) battery with the S/BC cathode shows high specific capacity and good cycling performance. It delivers a specific capacity of 1360 mA h g⁻¹ at 0.2C and remains at 790 mA h g⁻¹ after 200 cycles. At 1C, the Li–S with this composite cathode exhibits 601 mA h g⁻¹ after 150 cycles. This work offers a new kind of green material and a new method for Li–S batteries.

Bagasse-based carbon matrix with microporous structure and nitrogenous functional groups could have high sulfur loading and excellent polysulfide absorption capacity.     

Frequency of laboratory testing and associated abnormalities in patients with hypertension

Clinical practice guidelines recommend several routine laboratory tests in patients diagnosed with hypertension. However, the rates of clinically relevant laboratory abnormalities are unknown. Therefore, we conducted a retrospective cohort study using administrative and laboratory data of patients diagnosed with hypertension between April 2010 and March 2015 in Alberta, Canada. Laboratory investigations for renal function, serum electrolytes (sodium and potassium), low‐density lipoprotein (LDL) cholesterol, and diabetes (fasting blood glucose and hemoglobin A1c), measured within 1 year of diagnosis, were examined, and the frequency of abnormalities determined. A total of 225 296 cases of incident hypertension were identified. Of these, 74.3% received at least one of the four guideline‐recommended laboratory tests, but only 42.3% received all four tests. Patients who received any testing, compared to subjects who did not, were on average older (median age 55.9 vs 51.2 years, P < .001) and had more comorbidity (14.5% vs 2.8% with a Charlson comorbidity index ≥ 3, P < .001). Laboratory abnormalities with the potential to affect clinical decision‐making were more common among multi‐comorbid patients. Patients with renal dysfunction (6.7% vs 11.6%, 26.3%, P < .001), electrolyte abnormalities (9.8% vs 12.6%, 20.5%, P < .001), and diabetes (13.4% vs 25.1% vs 38.8%, P < .001) were found in patients with Charlson scores of 0 vs 1‐2 vs ≥3, respectively. Our study found most patients diagnosed with hypertension received some laboratory testing, but rates of laboratory testing and frequency of abnormalities varied by clinical context. Testing and abnormalities detected were both more common among older patients and patients with comorbidities.     

Identification and characterization of microsatellite markers for scleractinian coral Galaxea fascicularis and its symbiotic zooxanthellae

Nine polymorphic microsatellites markers were identified for Galaxea fascicularis symbionts and characterized in 29 samples from two populations. Four of them were derived from coral genome with 5–11 alleles, and the expected and observed heterozygosities ranging 0.67–0.89 and 0.25–0.69 respectively. Five were derived from zooxanthella genome amplified 0–3 alleles/locus per individual, while 2–4 alleles/locus with totally 13 genotypes in the two populations, which likely implied multiple DNA-polymorphic Symbiodinium species associated with single host and the populations. The genetic diversity of the two coral host populations was significantly greater than that of zooxanthella populations. These markers should be useful in various genetic applications involving both the coral host and the zooxanthella.
