偏见的自我调节研究述评

偏见不是不可避免的。个体能够依靠自我调节来控制偏见反应。拥有高控制偏见内部动机且低控制偏见外部动机的个体能最有效地控制偏见, 包括内隐偏见。这类个体的控制偏见动机的内化程度最高, 而内化程度高的控制偏见动机能自动起作用。四分过程模型能分离出自动过程和控制过程对内隐测量任务的影响, 因此能更好地解释自动激活的联接和自我调节是如何交互影响行为的。未来的研究应进一步探索如何发展控制偏见内部动机和对内隐控制偏见动机的测量等问题。     

Revisiting the learning-without-awareness question in human pavlovian autonomic conditioning: Focus on extinction in a dichotic listening paradigm

Numerous studies have indicated that, consistent with current “cognitive” accounts of information processing, human Pavlovian autonomic discrimination acquisition cannot occur without awareness of the CS-US relationship. However, extinction studies have suggested that awareness is not necessary, findings that, in information-processing terms, have been explained by assuming that the processing by the extinction stage is parallel (automatic) rather than serial (controlled). This explanation was tested in an 80-subject study. The first, acquisition phase was a standard semantic differential conditioning arrangement with a 96-db white noise as US, and a “long” CS-US interval of 8 s, with ten trials each of CS+ (paired with US) and CS− (unpaired) trials. In extinction (USs omitted), in order to obtain non-autonomic indices of processing and thereby test the information-processing account of “unaware” autonomic conditioning during extinction, a dichotic listening task was implemented, with the CSs presented in the unattended channel (ear), while the subject had to perform a semantic differential reaction task in an attended-to channel (other ear). In early extinction, the electrodermal response occurring at an interval of 9–15 s after CS onset (i.e., following placement of the US during acquisition) and the finger-pulse-volume response occurring at an interval of 4–11 s after CS onset both showed reliable conditioning, but reaction-time and subjective-report data for the recognized critical words indicated serial rather than parallel processing of the CSs during extinction.     

Evaluating the Acute Contributions of Dopaminergic Replacement to Gait With Obstacles in Parkinson's Disease

The influence of dopaminergic replacement (DR) on gait in people with Parkinson's disease (PD) is well documented. However, little is known about the acute effects of dopamine on more complex locomotor tasks that require visual guidance to avoid obstacles during gait. The authors investigated the influence of DR on locomotor behavior in a task where movement planning and control might be challenged by the height of the obstacle. The PD group included patients diagnosed with idiopathic PD (n = 12), as well as healthy controls (n = 12). Patients walked and stepped over obstacles of different heights before (OFF) and after (ON) levodopa intake. Spatial adjustments were not modulated by DR, but the step time to perform these anticipatory gait adjustments was longer only in PD-OFF (compared with healthy controls) when approaching the highest obstacle, but not PD-ON. During the crossing phase, trail limb toe clearance of PD patients was shorter than healthy controls only during the OFF state. ON-OFF comparisons were significantly different only for the time to reach the lead foot clearance over the highest obstacle. In summary, DR partially improved movement slowness but did not directly affect movement amplitude of lower limb regulation in this gait task.     

大转子延长截骨在THR术后感染一期翻修中的临床应用

评价大转子延长截骨并行单纯钢丝捆扎在人工髋关节置换（THR）术后感染一期翻修中的作用及对翻修假体的影响.选取2010年10月~2013年10月期间30例髋关节置换术后假体感染性松动并行一期翻修术的患者,随访时间（34.8＆#177;13.2）月,对患者手术时间、截骨长度和愈合时间、术前术后Harris评分及术后感染控制情况进行统计.30例患者髋关节术后评分明显高于术前,手术时间为（132.4＆#177;23.6）min,经大转子截骨长度为（11.4＆#177;2.6）cm,截骨愈合时间（3.8＆#177;1.3）个月.术后感染未见复发.因此THR术后感染的一期翻修术中应用大转子延长截骨方法能缩短手术时间,髋关节功能较术前明显改善.

Characterization Classes Defined without Equality

In this paper we mainly deal with first-order languages without equality and introduce a weak form of equality predicate, the so-called Leibniz equality. This equality is characterized algebraically by means of a natural concept of congruence; in any structure, it turns out to be the maximum congruence of the structure. We show that first-order logic without equality has two distinct complete semantics (fll semantics and reduced semantics) related by the reduction operator. The last and main part of the paper contains a series of Birkhoff-style theorems characterizing certain classes of structures defined without equality, not only full classes but also reduced ones.     

琥珀酰明胶容量治疗对脑死亡后血清TNF—α、IL－1β、IL－6水平的影响

为了观察脑死亡后不同液体容量治疗对血清肿瘤坏死因子－α（TNF—α）、白细胞介素－1β（IL-1β）和白细胞介素－6（IL－6）等炎症介质水平改变的影响,选用巴马小型猪15只,随机分为3组各5只,即对照组（C组）、4％改良琥珀酰明胶组（MFG组）及乳酸林格氏液组（RL组）。C组不建立脑死亡模型,给与乳酸林格氏液30ml·kg^-1·d^-1～40ml·kg^-1·d^-1。MGF组和RL组为脑死亡组,采用颅内加压法建立脑死亡模型,MFG组给与4％改良琥珀酰明胶溶液30ml·kg^-1·d^-1,RL组给与乳酸林格氏液30-40ml·kg^-1·d^-1。分别于麻醉后及首次判定脑死亡后3、16、12、18和24h留取血样,检测血清中TNF-α、IL-1β、IL--6水平。结果发现MGF组较RL组血压和心率平稳;RL组TNF--α、IL-1β和IL-6水平自脑死亡后3h点开始逐渐升高;MFG组TNF--α、IL--1β和IL-6水平脑死亡后3h点开始亦升高,但升高幅度均较RL组低;三组间自脑死亡后3h点开始,组间比较差异有统计学意义。提示脑死亡后血清炎症介质TNF—α、IL-1β和IL--6释放增加,琥珀酰明胶可抑制脑死亡后TNF--α、IL--6、IL-1β等炎症介质的释放,减轻炎症反应,改善机体状况。     

禀赋效应对产品更换决策的影响

以禀赋效应理论为研究基础, 通过两个情景实验对产品更换过程中买卖双方的决策心理进行了研究。实验1表明, 在以旧换新活动中新产品的买方对旧产品的价格有高估的倾向, 对新产品的价格有低估的倾向; 相反, 新产品的卖方对旧产品的价格有低估的倾向, 而对于新产品的价格有高估的倾向, 这说明产品更换决策中存在着双重的禀赋效应。实验2表明, 新产品的买方对旧产品的属性评价显著高于新产品的卖方, 对新产品的属性评价显著低于新产品的卖方, 说明属性评价也存在禀赋效应的特征。双重禀赋效应的存在从消费者行为的角度解释了为什么消费者会出现创新抵制行为。     

‘Who am I?’

The dreams and existential questions of those, who came into being in order to replace a dead person, pivot around a central cry: ‘Who am I?’ If conceived, born or designated as a replacement child, such an individual may suffer—even as an adult—from a rarely recognized unconscious confusion of identity, compounded by grief and survivors’ guilt. From before the child is born, the archetypal forces of death and life are joined in a fateful constellation; the soul of the replacement child bears the shadow of death from the very beginning of life. Hope for the replacement child lies in an emergence of true self as soul recreates original life. Analysis can help the replacement child experience a ‘rebirth into true life’, not as ‘the one who returned’, but as a psychologically newborn individual; the path of individuation countering the replacement child‘s identification with the dead. Jungian analysis offers unique concepts for understanding and healing the replacement child; C.G. Jung himself was born after two stillborn babies and an infant that lived only five days.
