"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。     

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.     

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.     

Developmental and sex-related differences in preschoolers' affective decision making

This study investigated developmental and sex-related differences in affective decision making, using a two-deck version of Children's Gambling Task administered to 3- and 4-year-old children. The main findings were that 4-year-old children displayed better decision-making performance than 3-year-olds. This effect was independent of developmental changes in inductive reasoning, language, and working memory. There were also sex differences in decision-making performance, which were apparent only in 3-year-old children and favored girls. Moreover, age predicted awareness of task and the correlation between the latter and decision-making performance was significant, but only in 4-year-old children. This study thus indicates that there is a remarkable developmental leap in affective decision making, whose effects are apparent around the age of 4, which according to our results, also marks the age when the correlation of declarative knowledge and decision-making performance becomes significant.     

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.     

Mood specific media use and emotion regulation: Patterns and individual differences

The present study examines moods in which individuals are most likely to utilize various forms of entertainment media and the emotion regulation tendencies that are associated with such preferences. Results of a questionnaire study (n = 229) show that mood specific media use may be captured by three factors: turning to media in a positive mood, in a negative mood or in a bored mood. Findings also show that various forms of difficulty regulating emotion (e.g., feeling out of control when upset) predict media use in negative or bored moods only. More specific analyses show that music use in negative moods is predicted by both positive indices (e.g., reflection tendencies) and negative indices of emotion regulation (e.g., rumination tendencies), while television use in negative moods is only predicted by negative indices of emotion regulation. Results are discussed in light of the psychological needs that selective media use may serve.     

Money and fame: vividness effects in the National Basketball Association

In his widely reprinted paper “On the Folly of Rewarding A, While Hoping for B,” Kerr argued that vividness was one of the major reasons for distorted rewards. Using both archival and survey data, the present paper directly tests Kerr's proposal by investigating whether, how, and why highly visible behaviors are over‐rewarded and less visible, but similarly (or more) important behaviors are under‐rewarded. The National Basketball Association (NBA) was chosen as the domain of this study because scoring is particularly vivid, even though both non‐scoring and scoring performances are critical for winning games. Findings from four studies demonstrated that the scoring performance of NBA players was weighed more heavily than their non‐scoring performance. Scorers were rewarded with higher salaries and received more support in the NBA All‐Star balloting than defenders, even though they might not necessarily make more contribution than their teammates. This pattern of findings suggests that the vividness effect may lead to pronounced differences in people's judgments, especially when they face abundant real‐world information with similar validity.

Power Imbalance and Employee Silence: The Role of Abusive Leadership,Power Distance Orientation,and Perceived Organisational Politics

Employee silence is a costly but omnipresent phenomenon in modern organisations. In this study, we focus on two forms of silence: defensive silence based on fear and acquiescent silence based on resignation. Given the power imbalance in supervisor–subordinate relationships, we hypothesise that abusive supervision is an antecedent of subordinates’ defensive silence and that a subordinate’s power distance orientation affects acquiescent silence. We investigate the interaction effects of abusive supervision and power distance orientation on these two types of silence. Perceived organisational politics may also aggravate such interactive effects. Based on data collected from 159 junior employees in China in two periods, we find that abusive supervision is associated with employee defensive silence and moderates high-power-distance employees’ tendency to engage in acquiescent silence. When perceiving high politics in the organisation, high-power-distance employees are more sensitive to abusive supervision and engage in more defensive silence. A highly political organisational context also accentuates abusive supervision’s moderating effect on the relation between employees’ power distance orientation and acquiescent silence. We conclude with theoretical and practical implications for the silence literature.
