公正世界信念对大学生学习成绩的影响:时间管理的解释

为探讨公正世界信念对大学生学习成绩的影响,并说明时间管理因素在二者关系中的作用机制,研究1以205名大学生为被试,采用问卷法探讨了公正世界信念通过时间管理对大学生实际学习成绩起作用的机制。结果表明,时间管理倾向在公正世界信念和学习成绩的关系中起部分中介作用。研究2随机选取120名大学生为被试,采用启动实验范式考察了公正世界信念对时间规划的影响。结果表明,当启动不公正信念时,个体计划学习投入时间显著减少,同时伴随娱乐等其他时间增加。总之,公正世界信念可部分通过影响大学生的时间管理进而影响其学习成绩,而且大学生对不公正信念更敏感。     

父母冲突损害青少年学业成绩:努力控制与课堂参与的中介作用

本研究采取方便取样法从山东省济宁市两所公立初中抽取815名学生作为被试,填写父母冲突特征量表、努力控制分量表和课堂参与量表,并以语文、数学和英语三门课程的期末考试成绩作为学业成绩的指标,考察父母冲突对青少年学业成绩的影响机制,特别是青少年努力控制和课堂参与的中介作用。结果显示：（1）父母冲突对青少年的学业成绩存在直接负向预测;（2）父母冲突通过损害青少年的努力控制而间接负向预测其学业成绩;（3）父母冲突通过依次损害青少年的努力控制能力和课堂参与而间接负向预测其学业成绩。本研究不仅启发教育工作者重视青少年学业不良的家庭风险因素,而且启发父母有意识地减少冲突,为孩子自控能力乃至学业发展创造良好的家庭环境。     

The relationship among resilience,rumination and posttraumatic growth in hemodialysis patients in North China

Research has indicated that clinical serious disease may lead to posttraumatic growth (PTG). However, little is known about PTG among hemodialysis (HD) patients. The study examined the relationship among resilience, rumination and PTG among Chinese HD patients. 196 HD patients were recruited from a tertiary hospital in a Northern city of China between 1 June 2015 and 30 May 2016. Patients were surveyed using the Posttraumatic Growth Inventory-Chinese version, Connor-Davidson Resilience Scale, and Chinese Event Related Rumination Inventory. Correlation analyses showed that resilience was most highly positively correlated with PTG (r = .70, p < .001), deliberate rumination moderately correlated to PTG (r = .50, p < .001), and intrusive rumination was lower negatively related to PTG (r = –.26, p < .001). Regression analyses showed that age, gender, duration of dialysis, resilience and deliberate rumination had significant associations with PTG (β = ?.31, p ＜ .0001; β = –.14, p = .002; β = .10, p = .032; β = .44, p < .001; β = .20, p < .001). They together explained 65% of the total variance in PTG (F [8,195] = 46.74, p < .001). However, intrusive rumination was not associated with PTG (p > .05). The results suggested that resilience and deliberate rumination may be instrumental for PTG improvement.     

Atomic and electronic structure of a carbon nitride compound prepared by magnetron sputtering

The atomic structure, chemical composition and chemical bonding state of a carbon nitride compound, synthesized by rf magnetron sputtering, have been studied by high-resolution electron microscopy, nanobeam diffraction and electron energy loss spectroscopy. It is revealed that the grain sizes of a crystalline compound in an amorphous matrix lie in the range 5-10 nm, and that the compound has a hexagonal structure with a = 0.324 nm and c = 0.404 nm. The C and N K edges are observed in the high-energy region of the electron-energy-loss spectrum. Only features corresponding to C sigma* bonds are found in the C K edge spectrum, which provides evidence for sp³ hybridization of C orbitals in the compound. Quantifying the electron-energy-loss spectra suggests that the compound is C₇N₁₀.     

A piezoelectric gyroscope based on thickness-shear modes of an AlN bimorph with inclined c-axes

We propose a new structure for piezoelectric gyroscope application. It consists of a two-layered plate of AlN with inclined c-axes. Through a theoretical analysis, it is shown that when the plate is electrically driven into thickness-shear (TSh) vibration in one direction and is rotating about the plate normal, the rotation causes a TSh vibration in a perpendicular direction with an electrical output which can be used to measure the angular rate of the rotation. Since AlN can be made into thin film devices much smaller than conventional crystal acoustic wave devices, the proposed gyroscope can be made much smaller than existing piezoelectric gyroscopes. The structure can also work with other crystals of class 6mm such as ZnO and polarized ceramics.

医患沟通新视角:论自我表露的临床应用

自我表露是人们进行正常社会交往的主要组成部分,关系到个体与他人关系的亲疏以及社会适应性。随着研究的深入,自我表露逐渐渗入临床医学等领域。通过对自我表露概念、意义、临床应用及其实施步骤的阐述,以期引起临床医护人员的重视,将自我表露恰当地应用于医疗护理工作中,从而有效促进医(护)患沟通,并进一步实现其治疗性作用。     

Family Therapy in China

This paper aims to provide an overview of the family therapy in mainland China, by analyzing its development, current situation and future directions. The authors argue that the history of family therapy can be understood as three stages: introductory stage from 1985 to 1994, “blossoming” stage from 1995 to 2004, and “fast growing” stage from 2005 to present. In every stage, we can see clear differences in each of the following fields: training (including training programs in universities and workshops held by companies or institutes), academics (including research articles, professional books and conferences), and general public environment (including media and policies). We also outline the development of China’s first university system family therapy training program as an example and evidence of family therapy’s significant present and future development in mainland China. Based on this, we highlight some points for future improvement in family therapy in mainland China, including developing indigenous theories and practice models, reinforcing training and research programs in university systems, and improving accreditation standard for all family therapists.     

TKA术后夹闭和开放引流管对出血量和输血量影响的比较研究

前瞻性研究全膝关节置换术（TKA）术后引流管夹闭4小时对患者术后出血量和输血量的影响。将我院2010年2月至2011年2月因骨性关节炎晚期行TKA的患者71例,随机分为两组。一组为夹闭引流管组,另一组为持续开放引流管组。两组均于术后48小时拔出引流管。将两组患者术前及术后1天、2天、3天的血红蛋白（HB）计数、术后引流液量及术后输血量进行比较。结果显示,夹闭引流管组与持续开放组患者相比,两组切口引流量存在差异。因此,与持续开放引流管方法相比,TKA术后采用夹闭引流管4小时的方法可以减少引流量,但不减少术后出血量及输血量。
