The modality effect on reading literacy: perspectives from students’ online reading habits,cognitive and metacognitive strategies,and web navigation skills across regions

This study tested the effects of the modality of reading formats (electronic vs. print), online reading habits (engagement in different online reading activities), use of cognitive strategies, metacognitive knowledge, and navigation skills on printed and electronic reading literacy across regions. Participants were 31,784 fifteen-year-old students (50.78% female) from 19 countries and economies in the 2009 Programme for International Student Assessment database. Results showed that students exhibited better reading literacy in the print environment. Moreover, information-seeking activities, control strategies, knowledge of metacognitive strategies, and navigation skills positively predicted reading literacy in both print and electronic formats for all regions, whereas social reading activities negatively predicted reading literacy in print and were most harmful for the Asian region in both formats. Memorization strategies were negatively associated with reading literacy in both formats for Australasian, Western and Eastern EU, and South American regions, but not for the Asian region. Online reading habits, regardless of types, had no impact on reading literacy in both formats for the South American region. The study findings provided suggestions for literacy instruction in the e-learning era across different regions.     

Elasto-inertial particle focusing under the viscoelastic flow of DNA solution in a square channel

Particle focusing is an essential step in a wide range of applications such as cell counting and sorting. Recently, viscoelastic particle focusing, which exploits the spatially non-uniform viscoelastic properties of a polymer solution under Poiseuille flow, has attracted much attention because the particles are focused along the channel centerline without any external force. Lateral particle migration in polymer solutions in square channels has been studied due to its practical importance in lab-on-a-chip applications. However, there are still many questions about how the rheological properties of the medium alter the equilibrium particle positions and about the flow rate ranges for particle focusing. In this study, we investigated lateral particle migration in a viscoelastic flow of DNA solution in a square microchannel. The elastic property is relevant due to the long relaxation time of a DNA molecule, even when the DNA concentration is extremely low. Further, the shear viscosity of the solution is essentially constant irrespective of shear rate. Our current results demonstrate that the particles migrate toward the channel centerline and the four corners of a square channel in the dilute DNA solution when the inertia is negligible (elasticity-dominant flow). As the flow rate increases, the multiple equilibrium particle positions are reduced to a single file along the channel centerline, due to the elasto-inertial particle focusing mechanism. The current results support that elasto-inertial particle focusing mechanism is a universal phenomenon in a viscoelastic fluid with constant shear viscosity (Boger fluid). Also, the effective flow rate ranges for three-dimensional particle focusing in the DNA solution were significantly higher and wider than those for the previous synthetic polymer solution case, which facilitates high throughput analysis of particulate systems. In addition, we demonstrated that the DNA solution can be applied to focus a wide range of particle sizes in a single channel and also align red blood cells without any significant deformation.     

太原地区冬春季PM2.5污染特征及影响因素

采用美国R&;P公司生产的TEOM系列1400A大气粒子（PM2.5）监测仪于2005年12月17日至2006年3月28日对太原地区PM2.5质量浓度进行在线观测。对观测期间2417个PM2.5小时平均浓度观测数据进行分析，得到小时平均浓度的平均值是247.6µg/m3(&#61617;193.7 µg/m3)。在50-100µg/m3之间的PM2.5浓度出现的频率最高，PM2.5小时平均浓度小于400 µg/m3的频率为84.1%。PM2.5浓度日变化为双峰双谷型。太原市区PM2.5浓度与风速、能见度和气压呈负相关，与相对湿度呈正相关。通过3d 后向轨迹分析了影响太原地区气团的主要传输路径，结果表明，100 m高度上空的后向轨迹可划分为7种基本类型，其中第3类轨迹对应的PM2.5浓度值为342.6 µg/m3，明显高于其它类型。这类轨迹主要是来自太原的西南方向；而来自东边方向的第1类轨迹对应的PM2.5浓度为261.1 µg/m3，也比来自西北方向的2、4类轨迹PM2.5浓度高。观测结果表明在沙尘暴影响严重的日期，太原地区PM2.5浓度会极大地增加，从而对大气环境形成严重的污染。     

原子核的中子皮厚度与非对称核物质态方程

挑选47组常用的Skyrme参数，采用Skyrme能量密度泛函结合拓展的Thomas－Fermi展开，用约束的密度变分法，我们计算了208Pb、112~124Sn 、 48Ca 、 96Zr、18O 等丰中子核的中子皮厚度并与实验数据分析抽取的中子皮厚度比较，研究了中子皮厚度与非对称核物质态方程中同位旋相关的对称能项之间的关系。我们发现中子皮厚度随对称能系数 a s 以及对称能在饱和密度附近的斜率L、曲率Ksym的增大呈现近似的线性增大的趋势，对称能越硬的核势确定的中子皮越厚。以反质子湮灭法拟合的参考实验值作为标准，我们给出对称能系数，对称能在饱和密度附近的斜率和曲率的参考范围分别为：as = 30 ~ 35MeV ，L = 20 ~ 100MeV，Ksym = -256 ~ 70MeV。满足这个条件的Skyrme 参数有：SLy0-SLy10、SkM*、SkP、SLy230a、SkMP、SKT1-3、SkI3、MSk1-2、SII 。
