中年Ⅱ型糖尿病人记忆损伤特点

本研究主要探讨中年Ⅱ型糖尿病人的记忆损伤特征。研究选取病人和对照各30人,控制年龄(65岁以下。病人组平均53岁,正常组52岁)、教育水平和相关疾病等因素。测试数字符号、数字工作记忆广度、动作记忆和无意义图形再认4项认知任务。结果发现：(1)病人组数字符号测试显著低于正常组;(2)在支持性条件记忆自由回忆中,病人组在有动作演练的高语义关联和无动作演练的低语义关联项目上显著低于对照组。出现分离现象;(3)在线索回忆中,病人组与对照组差异不显著;(4)两组数字工作记忆广度、无意义图形再认的成绩无差异。根据SPT(subject—performed task)研究理论对结果进行了分析,得出结论：中年Ⅱ型糖尿病人记忆的一般性信息加工能力未表现出受损,但特异信息加工受到损伤,并可能预测随年龄及病程进行而表现出一般性信息加工能力受损。     

"实践"的内在张力与话语转换契机的开启--当代马克思主义法律理论研究新探

当代马克思主义法律理论的研究面临着从批判性导向向建设性导向的话语转换的需要。而传统马克思主义法律理论对法律规范意义的一贯抛弃态度,是实现话语转换的困难所在。本文通过回溯马克思的实践思想,发现否弃法律的规范意义并非马克思思想的固有逻辑。而籍由马克思实践思想中所蕴涵着的实践的内在张力性框架,可以把法律的规范意义容纳进来,并在此基础上开启出马克思主义法律理论研究谋求自身内部话语转换的可能和契机。     

Never the Twain Shall Meet: A Critical Appraisal of the Combination of Discourse and Psychoanalytic Theory in Studies of Men and Masculinity

In recent years there have been a number of attempts by different researchers to study men and masculinity using a combination of discourse theory and psychoanalysis. The main reason for this development is the sense that, on its own, discourse theory provides an incomplete account of masculine subjectivity. Psychoanalysis is thought to be able to fill those gaps. In this paper I reviewed these arguments, provided an outline of the alleged deficiencies in discursive approaches to men and masculinity, and examined some of the work that has attempted the above synthesis. I argued that, for a number of reasons, such attempts are bound to fail. Instead, I argued that better progress can be made in studies of masculinity by remaining within the theoretical boundaries of Discursive Psychology.     

Differential effects of alcohol on associative versus item memory

Alcohol has detrimental effects on a range of cognitive processes, the most prominent being episodic memory. These deficits appear functionally similar to those observed within the normal aging population. We investigated whether an associative memory deficit, as found in older adults, would also be evident in young adults moderately intoxicated by alcohol. Participants were shown unrelated word pairs and then tested on both their item recognition (old/new item?) and associative recognition (intact/recombined pair?). Half the participants were under the influence of alcohol whereas the other half were sober. Alcohol impaired memory performance but significantly more so for associative than for item memory. Moreover, within the alcohol group, the associative memory deficit was significantly related to the amount of alcohol consumed. The findings suggest that not all aspects of episodic memory are equally impaired by alcohol, which may have practical implications for criminal investigations involving eye witnesses who have consumed alcohol.     

Consumer ethnocentrism,cultural sensitivity,and intention to purchase local products—evidence from Vietnam

• This study empirically investigates the impacts of consumer ethnocentrism and cultural sensitivity on both imported product judgment and intention to purchase local products in the context of a developing country—Vietnam. Structural equation modeling was used to test these impacts, utilizing a sample of 549 consumers. The results show that consumer ethnocentrism is negatively related to imported product judgment and positively related to intention to purchase local products. In addition, cultural sensitivity has a positive relationship with imported product judgment but not with consumer ethnocentrism. The results also indicate that the impacts of consumer ethnocentrism on imported product judgment and on intention to purchase local products are not different in terms of product categories, gender, income, and education levels. However, differences exist between younger and older consumers.

Involuntary attention and brightness contrast

Carrasco, Ling, and Read (2004) reported that involuntary attention increased perceived contrast. We replicated Carrasco et al. and then tested an alternative hypothesis: With stimuli near threshold, a peripheral cue biased observers to believe a stimulus had been presented in the cued location. Consistent with this hypothesis, the effect disappeared when we used higher-contrast stimuli. We further tested the guessing-bias hypothesis in three ways: (1) In a detection experiment, the cue affected bias, but did not increase d'; (2) when the cue followed the stimulus, we obtained the same results as when the cue preceded the stimulus; (3) in one experiment, some trials contained no stimulus, yet observers responded that the cued blank stimulus had higher contrast than the uncued blank stimulus. The results suggest that the effects of a noninformative peripheral cue are best described in terms of nonperceptual biases.     

Distance underestimation in virtual space is sensitive to gender but not activity-passivity or mode of interaction.

Four groups of undergraduates (half of each gender) experienced a movement along a corridor containing three distinctive objects, in a virtual environment (VE) with wide-screen projection. One group simulated walking along the virtual corridor using a proprietary step-exercise device. A second group moved along the corridor in conventional flying mode, depressing a keyboard key to initiate continuous forward motion. Two further groups observed the walking and flying participants, by viewing their progress on the screen. Participants then had to walk along a real equivalent but empty corridor, and indicate the positions of the three objects. All groups underestimated distances in the real corridor, the greatest underestimates occurring for the middle distance object. Males' underestimations were significantly lower than females' at all distances. However, there was no difference between the active participants and passive observers, nor between walking and flying conditions.     

腹腔镜在结直肠肿瘤手术中应用的回顾与思考

以腹腔镜为代表的微创外科技术迅速发展并取得了良好的临床效果.腹腔镜手术治疗结直肠癌存在较大争议,全盘否定或盲目应用都会影响腹部外科的发展.腹腔镜结直肠癌切除术都有其适应证并且对医生提出了更高的技术要求.随着腹腔镜技术的不断发展和完善,腹腔镜在结直肠癌手术的应用有广阔的发展空间.     

儿童归纳推理机制述评

在儿童早期归纳推理机制的探索过程中,一直存在着两种观点.一种认为儿童归纳推理是以类别或概念为基础的;另一种则认为儿童归纳推理是以相似性为基础的.这两种观点可能各自反应了儿童归纳推理的一个方面:前者可能说明的是儿童在知识丰富领域的归纳推理;而后者则可能说明的是儿童在知识贫乏领域的归纳推理.     

Karol Wojtyla and Emmanuel Levinas on the Embodied Self: the Forming of the Other as Moral Self-disclosure

The 'other' has taken on an increased theological significance for the Church in the advent of post-modern reflection, resulting in a myriad of possibilities for those who would reflect on the significance of the other in relation to the 'self', largely in connection with various theories of embodiment. Following Karol Wojtyla's (John Paul II) emphasis on the given-ness of the body I wish to illustrate a way in which the other might be understood theologically, informed by the insights of the continental philosophical tradition, specifically Emmanuel Levinas' phenomenological outline of the other as a key locus of ethical reflection. Bringing Levinas' continental philosophy into dialogue with Wojtyla's philosophical theology, it will be argued that the other must be re-approached in terms of their subjective self-disclosure, centring upon the en-fleshed and bodily form of the human person, who confronts us as a reflection of both that which is most other to ourselves (the divine) and paradoxically that which most resembles ourselves (the human). The other is always an en-fleshed subject and in their action, their subjective identity is disclosed on the relational level.
