不同类型的开放式无张力疝修补术的对照研究

比较经腹股沟和修补腹膜前间隙两类无张力癌修补术对腹股沟疝治疗结果的优缺点。将100例腹股沟疝患者随机分为经腹股沟修补组（60例）和经腹膜前间隙修补组（40例）,比较两组患者各手术相关指标、手术并发症及手术费用等方面区别。结果,经腹膜前间隙修补组较经腹股沟修补组手术时间略长（P〈0．05）、手术费用增加（P〈O．05）,而在手术并发症等方面两组差异无统计学意义（P〉0．05）。两类手术各有优缺点,选择何种术式则要因人、因手术医院而异。     

语义性别刻板印象对注意返回抑制的影响——来自行为和ERP的证据

采用ERP技术,以线索提示任务检验了性别刻板印象在返回抑制下的激活过程.实验以性别特征词为线索刺激,性别范畴词为目标刺激,要求被试忽略线索与目标语义仅对目标空间位置做出判断.反应时和ERP显示,线索化条件下刻板语义激活对位置判断产生显著影响,体现为女性刻板语义冲突增强了返回抑制.但非线索化条件下未观察到任何效应.实验结果表明,特定任务下性别刻板印象能够诱发注意偏向,但此过程易受注意线索影响,显示其有条件性.

Study on the deformation of nanocrystalline cobalt

A study was carried out on the deformation of nanocrystalline cobalt. For cold-rolled nanocrystalline cobalt, the X-ray diffraction peaks narrowed instead of broadened on deformation. The results of transmission electron microscopy showed that grain size (17.8?nm on average) was not increased. The results can be explained in terms of the production and activity of vacancies and vacancy clusters.     

The atomic structure of the dislocation cores in a small-angle grain boundary in BaTiO3 thin films

The atomic structure of the cores of the dislocations forming a [110] tilt boundary of 10^o misorientation in a BaTiO₃ film is characterized by means of focal-series reconstruction. Along the small-angle grain boundary, facets with different inclinations are accompanied by different types of dislocation. The dislocation with a Burgers vector of a [001] appears as a perfect edge type. Those with a Burgers vector of a [111] are dissociated into three partials with a Burgers vector of (a/3)[111], leading to two segments of stacking faults. Structural models of these dislocation cores are suggested on the basis of the phase of the reconstructed wavefunction and tested by simulation of the wavefunction.     

A general response style factor: Evidence from a multi-ethnic study in the Netherlands

In a cross-cultural study we addressed commonalities and differences of acquiescence, extremity, midpoint responding, and socially desirable responding that can be taken to constitute a single underlying response style. Participants were 548 Dutch nationals and 1116 first- and second-generation immigrants of Western and Non-Western origins in the Netherlands. Self-report measures of the four response styles, and personality traits were administered. Conventional, indirect measures of acquiescence, extremity, and midpoint responding were also calculated. A multigroup confirmatory factor analysis showed support for a general response style factor with positive loadings of extremity and socially desirable responding, and negative loadings of acquiescence and midpoint responding. The response style factor was strongly associated with personality (notably the “Big One” factor). Furthermore, acquiescence and impression management were related to agreeableness, extremity and midpoint responding to extraversion, and self-deceptive enhancement to neuroticism. These findings support a view that there is a general response style factor and that, in addition, each response style has some unique meaning. The ethnic groups differed significantly on response style use, with Non-Western immigrants showing higher acquiescence and midpoint responding than the other groups. The general response style factor can be interpreted as a communication filter that moderates self-reports. Implications are discussed.
