冠心病支架术后再狭窄的综合解析

综合正在成为冠心病治疗的重要原则.用综合的思想看待支架术后的再狭窄问题有重要意义,从支架术后的再狭窄的概念到再狭窄发病机制的认识以及防治方法,无不体现综合的思想.正是这种多学科、多领域的综合联系推动着冠心病支架术后的再狭窄防治方法的不断改进与提高,同时也加深了人们对该问题的认识.同时,也让我们认识到,从再狭窄这一个单纯的问题,可以体现出医生的综合素质与能力.综合思想在科研工作中具有重要作用.     

Auditory attentional blink: masking the second target is necessary, delayed masking is sufficient.

When two target items (T1 and T2) are presented in rapid succession among fillers, processing T2 is often impaired. This phenomenon is known as the attentional blink (AB). Within the visual modality, this second-target deficit generally occurs only if T2 is masked by a trailing item. The current study was designed to examine whether masking of T2 also plays a critical role in the auditory AB. Results showed a reliable AB effect even when the item following T2 was replaced by silence. However, the AB deficit was abolished when T2 was the last presented stimulus. Our results suggest that, as in vision, T2 masking is necessary for the AB to take place in audition, but that masking is effective even when delayed, providing evidence that the phenomenon shares some functional mechanisms across sensory modalities.     

胡煦与朱熹对"太极""道器"理解之分歧

胡煦是清初一位重要的易学家、理学家,他的思想有很多独到之处,持论酌于汉学、宋学之间,与朱子颇有异同.朱熹认为太极即是理,把理看作是万物的本体.胡煦则认为太极是本体,理只是其用,太极不仅立于形器之先,也在理之先.朱熹以理为形上之道,而以阴阳为形下之器.胡煦认为"一阴一阳之谓道",则阴阳应为形上之道,道与阴阳实为一也.胡煦与朱熹对"太极""道器"等概念理解的差异反映了清初学术界思想的转向.     

Characteristics of men who have sex with men on the internet but identify as heterosexual, compared with heterosexually identified men who have sex with women.

We compared men who have sex with other men on the Internet with the remainder of the sample of men who reported only sex with women on the Internet, in a sample of 1,846 Swedish men recruited from a major Swedish portal. We report on the self-identified heterosexual men in the sample who reported engaging in cybersex in the past year, and for whom there was complete data on sexual identity and the gender of cybersexual partners. Of the 244 cases with full data, 76% were heterosexual in both identity and behavior, 16% were gay or bisexual in identity and reported both male and female cybersexual contacts on the Internet, and 8% indicated their sexual preference was heterosexual but also reported at least one male sexual partner on the Internet. Thus, 11% of self-identified heterosexual men had sex with other men online. Comparing the two groups, the men who had sex with men (MSM) who did not identify (MSM-NI) spent significantly more time per week online, although a similar amount of time on sexual pursuits, as the heterosexual men. The MSM-NI were significantly more likely to agree that their online sexuality had affected their sexuality in a positive way, to have bought sex from prostitutes, to agree that they do things online that they would not do offline, have cybersex more often, use a web-camera and microphone more often, flirt and visit contact sites more often, and agree more often that sexual thoughts and behaviors are causing problems, desire to have sex creates problems, and sometimes fail to meet commitments due to their sexual behavior. These data taken together suggest that MSM-NI online are not uncommon and are characterized by the extent of their cybersexual involvement that sometimes extends to other men. Such men may rationalize this cybersex with other men as not, or minimally, sexual in much the same way as Humphreys characterized MSMs in public restrooms.     

Reglobalizing Realism by Going Local, or (How) Should Our Formulations of Scientific Realism be Informed about the Sciences?

In order to examine the fit between realism and science, one needs to address two issues: the unit of science question (realism about which parts of science?) and the contents of realism question (which realism about science?). Answering these questions is a matter of conceptual and empirical inquiry by way local case studies. Instead of the more ordinary abstract and global scientific realism, what we get is a doubly local scientific realism based on a bottom-up strategy. Representative formulations of the former kind are in terms of the truth and reality of the posits of current science, in terms of warranted belief, in terms of mind-independent unobservable entities. Using illustrations mainly from the social sciences, doubly local scientific realism denies the global applicability of such formulations and seeks to make adjustments in their elements in response to information about local units of science: It is sufficient for a realist to give the existence of an entity (and the truth of a theory) a chance, while in some areas we may be in s position to make justified claims about actual existence (and truth). Logical inquiry-independent existence is sufficient for the social and human sciences, while mind-independence will be fine for many other domains. It should not be insisted that the theoretical posits of realist science be strict unobservables in all areas: most theoretical posits of the social sciences are idealized commonsensibles, such as elements in folk psychology. Unsurprisingly, this sort of local strategy will create space for realism that is able to accommodate larger areas of science without sacrificing traditional realist intuitions.     

中小学教师健康坚韧性及影响因素的研究

坚韧性是一丛能够保护个体免于应激伤害的人格特质,包括承诺、控制和挑战三部分内容。以中小学教师为被试,采用问卷调查的方法考察教师的健康坚韧性状况和影响因素。研究发现,教师的健康坚韧性整体上较为理想,教龄、性别、婚姻状况、学校层次和学历水平是影响教师健康坚韧性的重要因素。     

应对风格问卷的初步编制

本研究提出一种关于应对风格的理论构想。根据此构想编制的应对风格问卷可将个体分为灵活应对、问题应对、情绪应对和异常应对四种应对风格。初步研究表明,此问卷具有较好的信度和效度。用此问卷对1115名被试进行了初步调查,发现灵活应对风格160人,问题应对风格420人,情绪应对风格394人,异常应对风格的141人。此量表的建立为我们今后进行压力与应对的研究提供了一个有效工具。

医疗保健政策与医患关系

医疗保健政策深刻地影响着医患关系,并左右着医患关系的发展与变化.在实行"以公平为主,兼顾效益"的福利性的医疗保健政策时期,我国的医患关系是和谐的.但自从医疗保健政策向"经济导向型"方向转变之后,国家大幅度减少了对卫生事业的投入,医院必须从病人身上取得卫生发展必要的资金,医药费用上涨是必然的,也失去了公平和公正,并最终导致医患关系的恶化.调整医患关系不能仅从医、患两方面着手,建立符合医学伦理的卫生政策,才是问题的关键.
