理性看待心房颤动导管消融成功率

随着心房颤动导管消融术的发展,其成功率不断提高,但医学上的消融成功并不一定等同于永久性治愈,且由于心房颤动的复杂性、消融终点多元性、不规范的术后随访制度和医疗体制不合理等诸多因素影响,导管消融成功率往往被无意或有意夸大,术后可能会因为达不到患者期望值而产生医疗纠纷。     

子团队:形成、类型、中间过程及影响

子团队是指在团队断裂带作用下而形成的一种集合体,它是对团队多样化深入探讨后所产生的结果,并已经逐渐成为团队研究的热点。从子团队的定义出发,对子团队的形成基础、类型、作用于绩效的过程变量、对团队结果的影响以及伴随这些环节的调节因素进行论述,并在此基础之上建构了子团队研究框架图。最后提出未来的研究应该对领导、情感、国家背景、社会网络和子团队测度在子团队研究中所扮演的角色做进一步的探索。     

个性心理因素与非理性金融行为研究

采用问卷法对个性心理因素中的人格、决策模式与非理性金融行为的关系进行了研究。研究结果表明：人格、决策模式对非理性金融行为有显著影响,不同人格类型、不同决策模式的个体的非理性金融行为差异显著。研究发现,人格、决策模式对各类非理性金融行为以及各类非理性金融行为总和的预测力皆达显著,并且对不同的非理性金融行为有不同预测力;理智型、即时型、依赖型的决策模式与感觉-直觉人格维度对非理性金融行为总和的预测力显著。     

Relationship of Inglehart's and Schwartz's value dimensions revisited

This study examines the relationship between Inglehart's and Schwartz's value dimensions—both at the individual and the country levels. By rotating one set of items towards the other, we show that these value dimensions have more in common than previously reported. The ranking of countries (N = 47) based on Schwartz's Embeddedness—Autonomy and the Survival—Self‐Expression dimensions reached a maximum of similarity, r = .82, after rotating Inglehart's factor scores 27 degrees clockwise. The correlation between the other pair of dimensions (Schwartz's Hierarchy‐Mastery—Egalitarianism‐Harmony and Inglehart's Traditional—Secular‐Rational values) was near zero before and after rotation. At the individual level (N = 46,444), positive correlations were found for Schwartz's Conservation—Openness dimension with both of Inglehart's dimensions (Survival—Self‐Expression and Traditional—Secular‐Rational values). The highest correlation with this Schwartz dimension was obtained at the Secular‐Rational/Self‐Expression diagonal, r = .24, after rotating the factor scores 45 degrees clockwise. We conclude that Schwartz's and Inglehart's originally proposed two‐dimensional value structures share one dimension at the country level and some commonality at the individual level, whereas the respective other pair of dimensions seem to be more or less unrelated.

直升机教养的内涵、影响和后效

直升机教养是父母对始成年期青少年普遍采用的一种教养方式,它是指父母给孩子过度的支持,较多地控制其行为,并不能给予孩子适合其年龄的自主权的教养方式。本文从直升机教养的概念辨析、影响因素和作用后效方面进行了系统梳理和整合分析,未来研究需要扩展研究对象和内容、精细探讨直升机教养的作用机制、重视我国始成年人的直升机教养,深入考察直升机教养与健康成长的因果关系。     

Response Selection Contributes to the Preparation Cost for Bimanual Asymmetric Movements

Movement preparation of bimanual asymmetric movements takes more time than bimanual symmetric movements in choice reaction-time conditions. This bimanual asymmetric cost may be caused by increased processing demands on any stage of movement preparation. The authors tested the contributions of each stage of movement preparation to the asymmetric cost by using the additive factors method. This involved altering the stimulus contrast, response compatibility, and response complexity. These manipulations changed the processing demands on stimulus identification, response selection, and response programming, respectively. Any manipulation with a larger reaction time cost than control suggests that stage contributes to the bimanual asymmetric cost. The bimanual asymmetric cost was larger for incompatible stimuli, which supports that response selection contributes to the bimanual asymmetric cost.

对吉林省516名公务员的血压及心血管疾病危险因素进行描述性分析,用二分类Logistic回归法筛选危险因素。公务员正常高值血压现患率为34．9％。正常高值血压人群体重指数、腰围、空腹血糖、总胆固醇、低密度脂蛋白胆固醇、甘油三酯、血清肌酐、血尿酸、心一踝血管指数水平以及代谢综合征患病率均高于正常血压组低于高血压组,高密度...     

抑制炎症因素在他汀类药物心血管疾病多效性中的作用

他汀类药物自1976年上市应用于临床治疗以来,其非调脂作用,即他汀类药物的多效性近些年来越来越引起人们的重视,尤其是抑制炎症因素方面。随着近些年来研究的不断深入,越来越多的证据表明C反应蛋白作为体内最敏感的炎性标志物之一参与了多种临床常见心血管疾病的发生发展过程。而他汀类药物随着REVERSAL、PROVEIT、MIR...
