登楼试验在低肺功能食管癌患者术前心肺功能评估中的作用研究

对需行食管癌手术的418例患者行术前静态肺功能检查后,按第一秒用力呼气量占预计值百分比（FEV1％）分为两组：肺功能正常组（NPF）和低肺功能组（LPF）。NPF组直接手术治疗,LPF组补充登楼试验,选择部分患者经术前功能锻炼后手术治疗,观察两组的临床情况。静态肺功能测定结果较差而进行登楼试验筛选后的部分患者可以通过功能锻炼提高心肺功能储备,从而能够接受手术治疗。     

论道德敬畏及其在个体道德生成中的作用

道德敬畏是指人们对道德法则,对善的事物及其社会价值与根源的强烈的崇敬和畏惧的道德情感体验.在人类道德发展史上,人类的道德敬畏大致经历了无知型的道德敬畏、形而上的道德敬畏和理性自觉的道德敬畏三种形态.道德敬畏的指向主要有四种,即敬畏自然、敬畏上帝、敬畏生命和敬畏规则.道德敬畏的功能和作用主要体现在:它是个体道德意识产生的重要的情感因素,是道德信念的重要组成部分和激励道德行为的内在动力.     

Patterns of Sexuality Communication Between Preadolescents and Their Mothers and Fathers

The purpose of the current study was to examine communication about sexual topics between preadolescents and their mothers and fathers. Participants were 135 African-American mothers, fathers, and their 9- to 12-year-old offspring. Each member of the triad completed a 10-item measure of communication about risk factors for sexual activity, sexual communication, and sexual risk prevention. A majority of parents and their preadolescents reported communication had occurred about most topics. Mothers and fathers were equally likely to communicate with sons whereas mothers were more likely to communicate with daughters than were fathers. Based on the study results, preadolescence may be the optimal time for parents to provide sexual risk prevention messages to their children before sexual behaviors are initiated.

Intergenerational transmission of neuropsychological executive functioning

Relationships between parent and child executive functioning were examined, controlling for the critical potential confound of IQ, in a family study involving 434 children (130 girls and 304 boys) and 376 parents from 204 community recruited families at high risk for the development of substance use disorder. Structural equation modeling found evidence of separate executive functioning and intelligence (IQ) latent variables. Mother’s and father’s executive functioning were associated with child’s executive functioning (beta = 0.34 for father–child and 0.51 for mother–child), independently of parental IQ, which as expected was associated with child’s IQ (beta = 0.52 for father–child and 0.54 for mother–child). Familial correlations also showed a significant relationship of executive functioning between parents and offspring. These findings clarify that key elements of the executive functioning construct are reliably differentiable from IQ, and are transmitted in families. This work supports the utility of the construct of executive function in further study of the mechanisms and etiology of externalizing psychopathologies.     

The Relevance of People Versus Objects in Explaining Females’ Advantage over Males in Appearance Accuracy

Do females remember their surroundings better than males? Does it matter who or what is in those surroundings? In small groups, 108 undergraduates from a Midwestern university in the USA were instructed to pay attention to a videotaped person (target) while seated in an office with an experimenter (non-target). Afterwards, in a surprise recall task, participants’ memory for the appearance of the target, non-target, and office was tested. Females’ greater interpersonal orientation was predicted to give them an advantage over males in memory for only the people. Results showed that females had better memory for the target and non-target but not the office. Discussion centers on the importance of people versus objects in explaining females’ greater appearance accuracy.     

How to keep a reversible figure from reversing: teasing out top-down and bottom-up processes

The nature of processes underlying our perception of reversible figures was examined through two experiments investigating the effects of prior exposure conditions on an observer's report of figural reversal. In experiment 1, observers were adapted over several minutes to an unambiguous version of a rotating Necker cube prior to the presentation of the standard ambiguous figure. Results indicated that adaptation produced an immediate bias to perceive the ambiguous figure in the opposite configuration (ie reverse bias) and to reduce reports of reversal over the test period. The introduction of a brief delay between the adaptation and test periods revealed that this bias is a highly transient effect and is only clearly evident when the adaptation and test figures are matched in size. In experiment 2, observers were primed with an unambiguous figure for a few seconds prior to the presentation of the standard ambiguous figure. In this case, the obtained bias strongly favored the observer's reporting the ambiguous figure to be in the same configuration as the adapting figure (ie positive bias); and neither introducing a delay period nor changing figure size had any effect. We conclude that these experiments reveal the distinct roles of transient, retinally localized neural processes as well as more stable, global processes under specifiable conditions.     

正确看待新生儿包皮环切术

新生儿包皮环切术通常被认为能减少尿路感染、成人阴茎癌甚至艾滋病毒感染危险,许多国家和地区常规为新生儿行包皮环切术。但近年来许多学者从医学和伦理等角度对此提出疑问,主张慎重对待新生儿包皮环切术。     

Effects of contour proximity and lightness on Delboeuf illusions created by circumscribed letters

32 observers judged the size of a letter, either an "A" or an "S," which was surrounded by a circle. Both letters were overestimated, but larger surrounding circles reduced the illusion. Decreasing the lightness contrast of the surrounding circle relative to the central letter diminished the illusion. The results suggest that, like the Delboeuf illusion, these circumscribed letters illusions are produced by interactions among size-coding neurons.     

Longitudinal construct validity of Brief Symptom Inventory subscales in schizophrenia

Longitudinal validity of Brief Symptom Inventory subscales was examined in a sample (N = 318) with schizophrenia-related illness measured at baseline and every 6 months for 3 years. Nonlinear factor analysis of items was used to test graded response models (GRMs) for subscales in isolation. The models varied in their within-time and between-times parameter constraints, with the homogeneous model being the least constrained, followed by the 2-parameter GRM and 1-parameter GRM. Results show that 4 subscales (Interpersonal Sensitivity, Hostility, Paranoid Ideation, Psychoticism) were consistent with the 1-parameter GRM, and 5 subscales (Somatization, Obsessive-Compulsive, Depression, Anxiety, Phobic Anxiety) were consistent with the 2-parameter GRM. There is evidence that the 9 subscales may be validly used to study change in single constructs over time.
