Abstract: ?目的?探讨宫颈鳞癌患者治疗后高危型人乳头瘤病毒(HR-HPV)感染的转阴规律,并分析影响其转阴的相关因素。方法?收集2011年1月至2012年12月在首都医科大学附属北京妇产医院接受治疗的宫颈鳞癌患者148例,其治疗前HR-HPV检测均阳性,观察宫颈鳞癌治疗后HR-HPV感染的转阴情况。结果?① 148例宫颈鳞癌患者接受治疗后,至随访期结束HR-HPV转阴的患者共134例(90.5%);② 其中随访半年、1年、1.5年、2年、2.5年及3年HR-HPV转阴率分别为68.9%、73.0%、77.7%、83.1%、86.5%及87.8%;③ 不同时间HR-HPV转阴的速率不同,以2年内转阴的速率最快,之后减慢;④ 单因素及多因素分析均显示临床分期、治疗方案及HPV分型是影响HR-HPV转阴的因素(P<0.05),而年龄、组织学分级、吸烟及是否使用安全套不是影响HR-HPV转阴的因素(P>0.05)。结论?① 宫颈鳞癌治疗后HR-HPV转阴率逐年升高,半年内转阴率达68.9%,以2年内转阴速率最快;② 临床分期、治疗方案及HPV分型是影响HR-HPV转阴的主要因素。

Abstract: 摘要: 对982名大学生的依恋、情绪调节策略、元情绪及心理弹性进行测查,考察依恋与心理弹性间关系的内在机制。结构方程模型分析结果显示:(1)依恋、情绪调节与元情绪均能显著预测心理弹性;(2)依恋焦虑通过认知重评和元情绪间接预测心理弹性;(3)依恋回避不但直接负向预测心理弹性,还会通过认知重评和元情绪间接预测心理弹性。本研究结果显示,情绪调节策略和元情绪能够解释依恋与心理弹性间关系的内在机制。
Abstract: There is considerable evidence that attachment security is associated with many cognitive, emotional, and social benefits, one of the ways is by fostering an open flexible, and optimistic approach to life’s diverse and unpredictable challenges, which is the core concept of psychological resilience (Caldwell & Shaver, 2012). Psychological resilience is the ability of individuals in otherwise normal circumstances to maintain relatively stable, healthy levels of psychological and physical functioning, as well as the capacity for generative experiences and positive emotions (Fletcher & Sarkar, 2013). Ample evidence in the literature have found that individuals higher in psychological resiliency are better able to recover from negative emotional experiences and flexibly adapt to the fluctuating demands of stressful experiences. The attachment system is, in itself, an emotion regulation device and the effects of the attachment system on emotion regulation can be charted (Mikulincer & Shaver, 2010). Attachment-system activation and proximity seeking are integral parts of a person’s regulatory efforts, and they play an important role in shaping a person’s emotional responses. Beyond these normative links between attachment processes and emotion regulation, individual differences in attachment-system functioning affect how people appraise emotion-eliciting events and the regulation. A sense of attachment security promotes the regulatory processes that allow emotions to be experienced and expressed without defensive distortion, which contribute to higher level of meta-emotion and more positive emotion experience (Fullam, 2002). In contrast, attachment insecurities contribute to distortion or denial of emotional experience, which result in defective meta-emotion and more health problem and negative emotion experience (Laan, Van Assen, & Vingerhoets Laan, 2012). Individual with an avoidant attachment style may inhibit or suppress their emotion, and anxiety attachment individuals would intensify the undesirable emotions. Consider of the regulation of affect is central to resilience and attachment, the purpose of this study is to explore the unclear mechanism between attachment and psychological resilience. In this study, we used the structure equation model to investigate whether emotion regulation strategies and meta-emotion mediated the relationship

Abstract: 摘要: 采用问卷法对369名青少年在初中阶段的积极适应状况进行历时三年的四次追踪测试,通过潜变量增长模型检验初一至初三期间个体积极适应的变化趋势,同时考察随时间稳定变量(学校转换)和随时间变化变量(压力知觉)对积极适应的影响。结果发现:1、从初一到初三,个体的自我肯定和行事效率均呈曲线上升趋势,且上升速度逐年下降;亲社会倾向呈线性上升趋势;积极应对则呈线性下降趋势;2、学校转变对初中生积极适应发展的影响较小;3、压力知觉对当时初中生的积极适应具有显著抑制作用。
Abstract: Social adjustment has been the core issue of developmental psychology. Positive adjustment is typically defined as the behavior that is consistent with social norms and benefits the individual’s survival and development across multiple domains that are self adjustment (self-affirmation), interpersonal adjustment (pro-social tendency), behavioral adjustment (acting efficiency) and environmental adjustment (active coping) respectively. Positive psychology indicates that positive adjustment is independent of negative adjustment, and the focus on positive function of social adjustment can facilitate social stability as well as the harmony between individual and environment. However, most previous research has focused on the negative function of social adjustment, such as problem behavior, negative emotion and so on. Much less is known about the developmental trajectories of positive adjustment and the contributing factors and mechanisms that underlie the development, particularly in life stage with an accumulation of changes and challenges. The transition to adolescence has been characterized as a critical period with the dramatic change resulted from school transition and sharp physical and psychological development. Thus, the development of positive adjustment plays an important role in adolescents’ healthy growth. Accordingly, a three-year longitudinal study was conducted to examine the change trajectories of positive adjustment, and how external factor (school transition) and internal factor (perceived pressure) shape the development for middle school students. A total of 369 seventh-grade adolescents were recruited from two middle schools and participated in the study. Among them, 290 adolescents (140 females and 150 males, mean age is 12.32 years, SD = 0.52) participated in all three consecutive years, in which 181 adolescents made the transition from primary school to different middle school and 108 continued in the same school (1 adolescent didn’t respond to the item). The study adopted Adolescents’ Social Adjustment Assessment Scale and Perceived Pressure Questionnaire for Middle School Students to assess four positive adjustment indices (self-affirmation, pro-social tendency, acting efficiency and active coping) and perceived pressure for four time points in November of 2012, May of 2013, December

Abstract:
电荷分解分析(CDA)是一种重要的深入研究电荷转移问题的方法。本文对CDA进行了介绍,阐述了计算中需要注意的问题,并提出了一种新的CDA形式,称为广义化的电荷分解分析(GCDA)。在HF、DFT级别GCDA与CDA等价,但GCDA能更好地用于后HF计算,而且还明确考虑了开壳层时的计算形式。通过以OC-BH3和顺式二氯二胺合铂体系作为测试实例,我们发现各种理论级别下GCDA的结果都较为合理且定性相符,但在定量上有所区别,特别是d项存在大体趋势:低HF成份的泛函 > 高HF成份的泛函 > HF ≥ MP2 > CCSD。文中还对GCDA计算时基组的选择进行了讨论。
Charge decomposition analysis (CDA) is an important method to study charge transfer problems in depths. In this paper, we introduced CDA method, elucidated the issues that needed attention in the calculation, and presented a new form of CDA, which was called GCDA. At HF and DFT levels, GCDA is equivalent to CDA, while GCDA is more applicable at post-HF level, and meantime its open-shell form is explicitly considered. By taking OC-BH3 and cis-dichlorodiamine as test cases, we find the GCDA results at various theoretical levels are reasonable and qualitatively consistent, but differ quantitatively; in particular, a rough trend exists in the d term: Functional with low HF composition > Functional with high HF composition > HF ≥ MP2 > CCSD. The paper also discussed the choice of basis-set in GCDA calculation.

Abstract:
《种族与历史,种族与文化》是列维?施特劳斯针对种族主义进行探讨的著作。在该书中,列维?施特劳斯不仅对种族主义的本质进行了分析,还向读者展现了文化多样性的真正内涵及其对人类文明的重要意义。列维?施特劳斯指出,文化多样性的最大意义在于让人类文明得以存在多种不同的可能性,而人们也应当避免这种多样性为强势的现代文明所抵消。
Race and History, Race and Culture is a monograph which Levi-Strauss wrote for the discussion of racism. In this book, Levi-Strauss not only analyzes the essence of racism, but also demonstrates the true meaning of cultural diversity and its significance to human civilization. Levi-Strauss argues that the most significant meaning of cultural diversity is to remain multiple possibilities for human civilization. Moreover, people should also try their best to keep the cultural diversity from the evasion of aggressive modern civilization.

Abstract: 针对破乳剂成分与结构对油田采出水破乳脱稳的影响机制仍不明确的问题,依据新疆油田二元驱实际采出水组成配制模拟二元复合驱采出水,考察有机破乳剂种类和结构及无机电解质对其破乳脱稳的影响.结果表明,合成有机破乳剂的起始剂种类对破乳脱稳的影响较大,起始剂含量具有一定影响,而EO/PO比的影响相对较小.PAC和Al2(SO4)3的破乳脱稳效果最好,投加量500mg/L时均能将剩余含油量降低到10mg/L以下;而FeSO4和ZnSO4次之,NH4Cl较差.破乳剂通过电性中和及与HPAM形成的协同絮凝作用,促进了油滴的碰撞聚并,达到了较好的破乳脱稳效果.
