解读现代版希波克拉底誓言

随着医学的飞速发展,医学伦理学、医学哲学被赋予了新的科学内涵。这一内涵在现代版"希波克拉底誓言"中得以具体体现。从行善原则、生命价值原则、尊重自主原则、公平公益原则、有利与不伤害原则、医疗最优化原则、医疗保密原则等方面对该誓言进行了全面阐述,其中蕴涵着丰富的社会哲学、价值哲学、道德哲学等哲学思想。     

稳定性冠心病介入治疗的理性思考

介入治疗是冠心病治疗的重要手段之一.但目前在稳定性冠心病的治疗中出现了过度使用的问题.因此我们必须理性地认识到,包括冠脉介入治疗(PCI)在内的血运重建措施只是重要的治疗手段之一,而绝非其全部.在稳定性冠心痛治疗中,健康教育、改变生活方式、充分的药物治疗也是不可或缺的部分.     

文化与人格研究中的几个问题

“文化与人格”包含着“文化中的人格”和“人格中的文化”两个命题。当今人格与文化研究中存在几个问题:人格特质的跨文化普遍性问题;人格与文化研究中的文化问题;人格与文化的作用机制问题。要解决这些问题:1.将主位研究与客位研究结合起来;2.将文化看作动态的过程;3.考虑到文化与人格之间起作用的中间机制;4.加强人格心理学与其它学科的联系。     

Spatial accuracy demand in aiming movements: kinematic analysis of subtended angle and tolerance width

Subtended angle has been assumed to be an important factor in both response programming time and kinematic characteristics of aiming movements. Support for this assumption has come mainly from studies in which circular targets have been used. However, with circular targets, the subtended angle covaries with the size of the target in the principal direction of the movement (tolerance width). The purpose of this study was to examine the effects of tolerance width and subtended angle on aiming movement with multiple targets. Participants first hit a 5-cm-diameter circular target located 8 cm to the left of a starting position and then moved another 8 cm left to hit either a 5-cm diameter circular target or a 5- x 1-cm rectangular target oriented either horizontally or vertically, depending on the condition. Analysis showed that reaction times and movement times were longer for the vertical rectangular target, which had a smaller tolerance width than the other two targets. In addition, the vertical rectangular target also showed a greater percentage of secondary-submovement trials, lower movement velocity, and higher peak vertical displacement. Overall, the results indicate that the tolerance width of the target may impose more constraints on aiming movements than subtended angle.

复归与超越:王重阳修道论与老庄思想的关系

王重阳创立的以"全真而仙"为核心的修道论,远承老庄之学,融贯儒佛思想,分别从"全真"、"修心"、"真行"等不同层面,把老庄道家的"见素抱朴""法贵天真"思想,自然超脱的养心论和老子"不善者吾亦善之"的慈善济世思想推向了一个新的高度,实现了对老庄思想的复归与超越,增强了道教的普世性,提升了道教的思想水平。     

Brain activation detection by neighborhood one-class SVM

Brain activation detection is an important problem in fMRI data analysis. In this paper, we propose a data-driven activation detection method called neighborhood one-class SVM (NOC-SVM). Based on the probability distribution assumption of the one-class SVM algorithm and the neighborhood consistency hypothesis, NOC-SVM identifies a voxel as either an activated or non-activated voxel by a weighted distance between its near neighbors and a hyperplane in a high-dimensional kernel space. The proposed NOC-SVM are evaluated by using both synthetic and real datasets. On two synthetic datasets with different SNRs, NOC-SVM performs better than K-means and fuzzy K-means clustering and is comparable to POM. On a real fMRI dataset, NOC-SVM can discover activated regions similar to K-means and fuzzy K-means. These results show that the proposed algorithm is an effective activation detection method for fMRI data analysis. Furthermore, it is stabler than K-means and fuzzy K-means clustering.     

Multi-aspect data analysis for investigating human computation mechanism

In the paper, we present a multi-aspect data analysis approach for investigating human computation mechanism. Multi-aspect analysis in multiple human brain data sources is an important methodology in Brain Informatics, which emphasizes on a systematic way for investigating human information processing mechanisms, including measuring, collecting, modeling, transforming, managing, and mining multiple human brain data obtained from various cognitive experiments by using powerful equipments, such as fMRI and EEG. After giving an outline of Brain Informatics methodology, we describe how to design cognitive experiments of mental arithmetic task with multiple difficulty levels for obtaining multiple EEG and fMRI data sources, and how to analyze such data for investigating the spatiotemporal characteristics and flow of human computation processing. Such an investigation can be regarded as a case study using Brain Informatics methodology. Experimental results show the usefulness of our approach.

Resource availability hypothesis: Perceived financial and caloric status affect individuals' height preferences for potential partners

Height is an important concern in human mate choices. Prior research indicates that people who live in areas with abundant resources differ from those who live in areas with scarce resources regarding height preferences. Based on a health‐maximizing principle, we propose a resource availability account for such differences. Compared with women's height preferences, men's height preferences are hypothesized to be more dependent on either financial or caloric resource availability. Specifically, taller females would be more preferred by males who are poor in resources than those who are rich in resources. Results from three studies supported these hypotheses. In Study 1, men from remote areas of China who had lower family income preferred taller women more than those from eastern China who had higher family income. In Study 2, men who were financially dissatisfied preferred taller women more than those who were financially satisfied. In Study 3, men with low caloric status preferred taller women more than men with high caloric status. In addition, women's height preferences in Studies 1, 2 and 3 were less determined by resource availability. These findings suggest that height preferences are changeable, depending on financial or caloric status.
