医患关系的本质属性及其立法取向   总被引:8,自引:0,他引:8  
考察医患关系的本质属性,结合国家医疗事业的公益性、医疗立法的宗旨和发展趋势,得出如下结论:医患关系本质平等,医事法属平权法。医事法律关系本质平等,是一种民事法律关系,现行医患关系立法体系下医患关系的某些特征,不能反映医事法律关系的本质属性。  相似文献

儿童反语理解的心理机制   总被引:5,自引:0,他引:5  
反语是指使用与本意相反的字面形式表达本意的一种修辞形式,在儿童言语发展领域中是一种难度较大的认知对象。该对儿童在反语理解任务中的困难根源进行了探讨,介绍了目前关于儿童反语理解的心理机制研究的两种主要途径,一是采用成人反语识别理论去解释儿童反语理解的心理过程,二是从二阶心理理论角度开展的解释儿童反语理解的心理机制的尝试,最后在暗示假装理论和二阶心理理论的框架下对现有的研究证据进行了整合的讨论,并对未来研究提出了建议。  相似文献

青少年吸烟行为的预防与干预   总被引:15,自引:0,他引:15  
方晓义  林丹华 《心理学报》2003,35(3):379-386
以两所普通中学的573名初一、初二、高一和高二的学生为被试,随机将每个年级的两个斑分成干预组和控制组,干预组接受名为“远离香烟”(SAFT)的预防和干预方案,方案包括四个成分:即健康教育、识别并抵制同伴压力、大众媒体影响以及吸烟认知,以达到延缓或减少青少年吸烟行为的目的。方案共包括7次活动,每次45分钟,每周开展一次活动,共持续7周。结果发现:(1)干预组后测中的上个月吸烟行为比前测降低了5.2%,而控制组后测吸烟行为则上升了2.3%。同样的趋势表现在不同性别、不同年级的青少年身上;(2)预防和干预方案对减少干预组偶尔吸烟者的吸烟行为尤其有效;(3)在吸烟认知的转变上,干预组后测比前测更显著或接近显著地反对吸烟会带来友谊和形象等方面的好处,更赞同吸烟的危害性。而控制组则正相反;(4)方案可以有效地提高干预组的抵制技能;(5)在所有的干预成分中,只有后测吸烟与友谊的认识以及吸烟危害认识可以显著地预测干预组青少年的后测吸烟行为,而没有一个变量可预测控制组后测吸烟行为;(6)预防和干预条件通过后测吸烟好处、吸烟危害认识间接地对青少年后测吸烟行为产生影响。  相似文献

Decision‐makers are sometimes depicted as impulsive and overly influenced by ‘hot’, affective factors. The present research suggests that decision‐makers may be too ‘cold’ and overly focus on rationalistic attributes, such as economic values, quantitative specifications, and functions. In support of this proposition, we find a systematic inconsistency between predicted experience and decision. That is, people are more likely to favor a rationalistically‐superior option when they make a decision than when they predict experience. We discuss how this work contributes to research on predicted and decision utilities; we also discuss when decision‐makers overweight hot factors and when they overweight cold factors.

Research has shown that when the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) is administered with instructions designed to make people aware of the validity indexes and when people are encouraged to respond honestly rather than invalidate the test through defensiveness, their scores on validity scales suggest a more candid responding. Before such modified administration procedures can be broadly used to increase the validity of the MMPI (Hathaway & McKinley, 1943) profiles, it is necessary to have more information about the effect of the altered instructions on test performance of people in general. This study involved administering the MMPI-2 to a group of 218 "normals" (college students) with instructions that differed from traditional instructions. Specifically, the test instructions were altered to explain more about the test and the presence of validity scales to apprise participants that disingenuous responding can be detected. The responses of college students taking the test under altered instructions were compared with those of a similar sample of 150 college students who took the test under standard instructions. Although under altered conditions there was a statistically significant tendency for measures assessing defensiveness (L, K, and S) to be lower for some participants (women but not men), the differences were trivial. Modified instructions made little practical difference in test performance when people who were not motivated to deceive on the test were informed of the presence of validity checks on the test.  相似文献

采用亲职压力量表和对立违抗行为表现评估表调查了来自北京、山东和云南三地14所小学有ODD(oppositional defiant disorder)行为表现的301名儿童及其父母。通过为期两年的追踪研究,采用交叉滞后分析探讨了父母亲职压力与儿童的ODD行为之间的关系。结果发现:(1)在第一年和第二年的数据中,父母亲职压力和儿童的ODD行为表现均存在显著正相关;(2)第一年和第二年的父母亲职压力得分显著正相关,同样,两年的儿童ODD行为表现得分也显著正相关;(3)交叉滞后分析发现,对于有ODD行为表现的男孩来说,其父母第一年的亲职压力能预测他们第二年的ODD行为表现,但对于有ODD行为表现的女孩来说,其父母第一年的亲职压力并不能预测她们第二年的ODD行为表现;而不管是男孩,还是女孩,第一年的ODD行为表现都不能预测第二年的父母亲职压力。研究结果揭示出男孩父母的亲职压力可预测男孩的ODD行为表现,而不论是男孩或女孩的ODD行为表现都不能预测其父母亲职压力,说明父母亲职压力可能是男孩ODD行为表现的影响因素。  相似文献

Governmental research grants are financially supported by taxpayers to meet financial requirements of research, particularly research that is unlikely to be supported by private funds. Researchers reward donors by producing knowledge. Publishing research results in an academic journal reflects achievement by researchers; however, receiving a grant award does not. The latter only provides the researcher with the capacity to perform his/her research. Applicants may receive more financial support than they actually need because there is no strict audit on the amount of money requested by each research proposal. There are fewer opportunities to apply for a governmental grant than there are for publishing an academic article, and the application process for governmental grants is not flexible. Some potentially innovative research may be impeded by the intense competition among scientific researchers applying for financial support. Researchers face stiffer competition at this stage than at the stage of publishing results. This paper suggests that scientific foundations can improve their efficiency by giving funding preference to economic proposals. Methods for estimating the efficiency of grants are proposed. The practice followed by the Small Grants for Exploratory Research programme of the National Science Foundation validates my analysis and recommendations.  相似文献

This study investigates relationships and characteristics of participation in cycling in Melbourne, Australia, as an expression of place and displacement among persons from culturally and linguistically diverse origins including Asia (i.e. Vietnam, Sri Lanka and Japan) and Arab Africa (i.e. Saudi Arabia, Eritrea and Sudan). Using a mixed‐method approach, results indicated that despite a significant number of migrants to Australia with origins in places where cycling is a common mode of transport and activity, a large number of newly arrived and marginalised migrants and refugees are less likely to engage in cycling. Cyclists' identity, citizenship, social‐economic marginalisation and residential geographic isolation significantly impacted on their cycling in Melbourne. Although cycling is considered accessible, environmentally friendly, healthy and functional, the results indicated that this view may only represent and be shared by selected citizens. In short, culturally and linguistically diverse participants identified cycling behaviour differently in Australia in comparison with cycling in their countries of origin. The results contribute to knowledge in highlighting the extent of displacement facing marginalised communities that evolves in everyday practices of local mobility. The study identified a number of paradoxes facing mainstream policy makers, researchers and cycling advocates who tend to take cycling participation for granted as non‐political and universal.

Male–male vocal competition in anuran species is critical for mating success; however, it is also highly time-consuming, energetically demanding and likely to increase predation risks. Thus, we hypothesized that changes in the social context would cause male vocal competition to change in real time in order to minimize the costs and maximize the benefits of competition. To test this hypothesis, we assessed the effect of repeating playbacks of either white noise (WN) or male advertisement calls on male call production in the Emei music frog (Babina daunchina), a species in which males build mud-retuse burrows and call from within these nests. Previous studies have shown that calls produced from inside burrows are highly sexually attractive (HSA) to females while those produced outside nests are of low sexual attractiveness (LSA). Results showed that most subjects called responsively after the end of WN playbacks but before the onset of conspecific call stimuli although call numbers were similar, indicating that while males adjusted competitive patterns according to the biological significance of signals, their competitive motivation did not change. Furthermore, these data indicate that the frogs had evolved the ability of interval timing. Moreover, when the inter-stimulus interval (ISI) between playbacks was varied, the subjects preferentially competed with HSA calls when the ISI was short (<4 s) but responded equally to HSA and LSA calls if the ISI was long (≥4 s), suggesting that males allocate competitive efforts depending on both the perceived sexual attractiveness of rivals and the time available for calling. Notably, approximately two-thirds of male calls occurred in response to HSA calls, a preference rate comparable to that previously found for females in phonotaxis experiments and consistent with the idea that the mechanisms underlying both the male’s competitive responses to rivals and the female’s preferences toward potential mates coevolved under the same selective pressure.  相似文献
