微创医疗的决策思考与实践——兼论微创手术最佳适应证的选择

微创医学是一个新的医学理论体系。在具体临床医疗决策过程中如何运用微创医学理论是一个必须解决的理论和实践问题。微创医学人文观、科学观、技术观和社会观是医疗微创化决策思想的主要内容,在实践中具有重要的指导意义,尤其是对于微创手术最佳适应证的选择。     

我国社区卫生服务发展的障碍与对策研究

自1996年试点至今,我国社区卫生服务在政策支持、覆盖面、社区卫生服务站(点)的数量、人员的素质和群众的意识等都取得了令人瞩目的成绩.但是,我国的社区卫生服务尚处于初级阶段,在发展过程中还存在很多的问题,亟待采取有力的措施,克服存在的障碍,进一步完善我国的社区卫生服务体系.     

最简群体范式的操作、心理机制及新应用

最简群体范式作为研究群际关系的有效工具,受到社会心理学家广泛重视。除经典任务程序、随机分配程序外,新近发展出想象程序、记忆程序、自我卷入、计算机模拟群体互动模式等分类操作。最简群体范式具有随机性、完全匿名性和无关自我功利性等特点,可以从群体推断自我、自我推断群体及社会认同整合三个视角解释其心理机制。目前,最简群体范式在社会认知加工、社会心理偏好、社会互动行为及神经生理反应等领域开始广泛应用。     

乳腺微乳头状癌的临床病理特征分析

回顾性分析乳腺浸润性微乳头状癌（IMPC）的临床病理特征.选取河北医科大学第四医院乳腺中心手术切除并经病理证实的女性原发性乳腺癌共3 383例,筛选出符合IMPC为实验组,同期乳腺浸润性导管癌（IDC）为对照组.结果显示,本组IMPC 167例,占同期乳腺癌4.94％,年龄29岁～80岁,中位年龄54岁.淋巴结转移者共135例,占80.8％,淋巴结转移数目≥4个共105例,占62.9％,HER2阳性率58.7％,与IDC组相比差异均有统计学意义（P＜0.05）.IMPC为一种少见类型的浸润性乳腺癌,具有淋巴管侵袭性强、淋巴结转移率高的生物学行为.应与其他类型肿瘤进行鉴别,明确诊断.     

Regulatory focus theory: Disentangling goals and strategies

The purpose of this research was to develop and test the Regulatory Goals and Strategies Questionnaire (RGSQ) to promote conceptual and empirical clarity in the literature on regulatory focus theory (RFT). According to RFT, construing an end-state as a maximal goal (ideal, gain, and advancement) elicits the adoption of an eager promotion-focused strategy, whereas construing an end-state as a minimal goal (ought, non-loss, and security) elicits the adoption of a vigilant prevention-focused strategy. This means that promotion-focused eagerness and prevention-focused vigilance can be elicited by various goals and that eager and vigilant strategies are in fact separate from goals. However, extant measurement instruments have not treated them as such. The RGSQ was developed to distinguish various maximal and minimal goals and to separate these goals from promotion- and prevention-focused strategies of eagerness and vigilance. Across three studies that combine six samples (total N = 1848), we examined the factor structure and nomological network of the RGSQ (Study 1: four samples of students and adults) and its predictive validity in a task context (Study 2) and working sample (Study 3). Overall, we found support for the RGSQ's validity and demonstrated that the RGSQ operationalizes regulatory focus in accordance with the theory's core assumptions.     

Acquisition and maintenance of trusting behavior

This study determined whether a two-person exchange situation contained natural contingencies for trusting behavior or whether external contingencies were necessary. Pairs of college students worked matching-to-sample problems for money. On each trial there was one problem and the subjects determined which of them would solve it. Trusting behavior was defined as an increase in the number of consecutive problems each subject allowed his partner to work during sessions that also ended with an equitable distribution. Simply, trust was a temporary deviation from equity. A subject could give the problem to the other person (cooperate), or not respond and let the other person take the problem (share). Other possibilities were for both subjects to try to take the problem (complete), or for neither subject to respond and thereby let the person who worked the last problem also work the next one (passive trust). When only four lever pulls were required to distribute a problem (no external contingencies to reach either equity or trust) subjects reached equity, but only minimal trust (strict alternation of single problems) developed in 18 sessions. When 30 or 60 lever pulls were required to distribute a problem (smaller response requirement for passive trust and therefore a contingency for trust), trusting behavior developed after a few sessions (fixed ratio 30) or after several trials of the first session (fixed ratio 60) and it ordinarily expanded gradually to 10 to 15 consecutive problems through passive trust. The aversiveness of the inequity involved in trusting appears to necessitate a contingency for acquisition. Once trust develops, however, this aversiveness is reduced as subjects learn the inequity is only temporary (e.g., once trust was acquired at fixed ratio 60 it was maintained at fixed ratio 4, which would not initially produce it), and the direction of the inequity appears to become of questionable importance (e.g., being behind was alternated over rather than within sessions and usually not in a systematic manner).

Effects of minimal social cues on trust in the investment game

In anonymous game tasks, individuals’ prosocial behaviour was shown to increase when those individuals were provided with social cues from a third party or bystander. It has been suggested that those social cues can be presented using a configuration suggestive of a face with ‘watching eyes’. This led us to question whether it was possible to provide the watching‐eyes configuration with even weaker facial information, such as a simple dot pattern. By using a minimal social cue paradigm, such as the one described above, the present research found that individuals’ trust toward the trustee increased when they detected the watching‐eyes dot pattern as a source of social cues in two settings: a hypothetical investment game for both college students (Study 1) and customs officers (Study 2); and an actual investment game for college students (Study 3).     

Negation in the Context of Gaggle Theory

We study an application of gaggle theory to unary negative modal operators. First we treat negation as impossibility and get a minimal logic system Ki that has a perp semantics. Dunn's kite of different negations can be dealt with in the extensions of this basic logic K_i. Next we treat negation as “unnecessity” and use a characteristic semantics for different negations in a kite which is dual to Dunn's original one. K_u is the minimal logic that has a characteristic semantics. We also show that Shramko's falsification logic FL can be incorporated into some extension of this basic logic K_u. Finally, we unite the two basic logics K_i and K_u together to get a negative modal logic K_-, which is dual to the positive modal logic K₊ in [7]. Shramko has suggested an extension of Dunn's kite and also a dual version in [12]. He also suggested combining them into a “united” kite. We give a united semantics for this united kite of negations.
