This study examined the effects of in utero exposure to maternal depression and Superstorm Sandy, a hurricane that hit metropolitan New York in 2012, on infant temperament at 6 months. Temperament was assessed using the Infant Behavior Questionnaire-Revised. Maternal depression was measured by the Edinburgh Postnatal Depression Scale. The main effects and the interaction of maternal depression and Sandy exposure on infant temperament were examined using a multivariable generalized linear model. Results show that prenatal maternal depression was associated with lower emotion regulation and greater distress. Stratification and interaction analyses suggested that the adverse effects of prenatal maternal depression on problematic temperament were amplified by in utero Sandy exposure. This study underscores the importance of providing prenatal screening and treatment for maternal depression during pregnancy while also identifying high-risk families who may have suffered from disaster-related traumas to provide necessary services. As the frequency of natural disasters may increase due to climate change, it is important to understand the consequences of in utero stress on child development and to formulate plans for early identification. 相似文献

The effects of pressure on the mechanical and dynamical stability of NaAlSi have been fully investigated by first-principles calculations within the generalised gradient approximation (GGA). The obtained results show that the optimised lattice constants, atomic positions and elastic constants at ambient pressure are in good agreement with the available experimental and theoretical data. The lattice constants decrease monotonically with increasing pressure. The elastic constant C11, C12, C13, C33 and C66 increase while C44 decreases with increasing pressure. It is found that NaAlSi is mechanically unstable when the pressure is above 25.97?GPa. The phonon-dispersion curves along several high symmetry lines are obtained. The phonon frequencies at the Z point decrease with increasing pressure and completely soften to zero at 27.52?GPa, further confirming the structural instability of NaAlSi. 相似文献

运用广义回归神经网络(GRNN)方法对小样本多维项目反应理论(MIRT)补偿性模型的项目参数进行估计,尝试解决传统参数估计方法样本数量要求较大的问题。MIRT双参数Logistic补偿模型被设置为二级计分的二维模型。首先,模拟二维能力参数、项目参数值与考生作答矩阵。其次,把通过主成分分析得到的前两个因子在每个题目上的载荷作为区分度的初始值以及题目通过率作为难度的初始值,这两个指标的初始值作为神经网络的输入。集成100个神经网络,其输出值的均值作为MIRT的项目参数估计值。最后,设置2×2种(能力相关水平:0.3和0.7; 两种估计方法:GRNN和MCMC方法)实验处理,对GRNN和MCMC估计方法的返真性进行比较。结果表明,小样本的情况下,基于GRNN集成方法的参数估计结果优于MCMC方法。 相似文献

拼音文字文本阅读研究发现,同青年人相比,老年人在阅读过程中有更多的跳读发生、向前眼跳幅度更长、回视次数更多。基于这些研究结果,研究者提出了老年人阅读的“风险阅读”策略。为探究在中文阅读过程中老年人的加工特点以及与拼音文字阅读的策略异同,实验采用镜像和正常两种方式呈现文本进行了考察。结果发现,在中文阅读过程中,相较于青年人,老年人的跳读率更低,向前眼跳幅度更小,采用的是一种更为谨慎的阅读策略。在镜像呈现的条件下,老年人与青年人之间的跳读率没有显著差异,在正常呈现的条件下,老年人的跳读率显著低于青年,表明在汉语阅读中老年人采取更加谨慎的阅读策略与其副中央凹加工能力下降,以及汉语与拼音文字两种不同书写系统的基本属性有关。 相似文献

The Attitudes Toward Religion Scale (ATRS) was developed to access the level of interest in and position toward the five state-approved religions in China. Data were analysed across two samples of Chinese college students. With Sample 1 (N = 278), exploratory factor analyses were used to select the 10 ATRS items corresponding to two factors: Interest and Position. With Sample 2, confirmatory factor analyses (N = 270) cross-validated the two-factor oblique model as well as a bifactor model. Cronbach alphas of ATRS subscale scores in the two samples ranged from .75 to .85. ATRS-Interest and Position were both positively associated with number of close relationships with religious people. In addition, negative attitudes toward religion was associated with being religiously proselytised by strangers. Moreover, female students reported more favourable attitudes toward religion compared to their male counterparts. The overall results support ATRS as a psychometrically strong and promising measure. 相似文献

The current study applied a 2 × 2 experimental design to investigate the effects of ongoing task absorption on event-based prospective memory performance of children aged 3 and 5 years. Children were required to label pictures as ongoing task but to remember to refrain from picture naming and to respond to the target cues in a different way as the prospective memory task. Two differently absorbing ongoing tasks (high absorbing scenario game task vs. low absorbing computer-based task) were administered. Results indicated that prospective memory performance of 5-year-old children was significantly better than that of 3-year-old children. Ongoing task absorption affected the ongoing task performance of preschoolers, but not overall prospective memory performance. Only the 3-year-olds were negatively affected by high ongoing task absorption, which was not the case for the 5-year-olds. The findings are discussed within the light of the multiprocess theory. 相似文献

This study aimed (i) to investigate the relationships among socioeconomic status, disease activity, quality of life, and the psychological status in Chinese rheumatoid arthritis (RA) patients; (ii) to explore the possible risk factors of anxiety and depression. A total of 160 RA patients underwent standardized laboratory examinations and completed several questionnaires. Independent samples t-tests, χ2 analyses, and logistic regression modeling were used to analyze the data. We found 30.6% RA patients were anxiety, and 27.5% had depression, which were significantly higher than the control group (7.8 and 11.7%, respectively). And there were significant correlations among education, pain, disease activity, medication adherence, functional capacity, quality of life, and anxiety/depression. Meanwhile, logistic regression analysis revealed that poor quality of life and low education level were significantly associated with anxiety/depression in RA patients. In conclusion, there were significant relationships among education, quality of life, and anxiety/depression in Chinese RA patients. 相似文献
