念佛、净土观念与早期禅宗弥勒信仰

弥勒信仰乃最早传入中土的净土信仰。本文从净土观念、弥勒信仰与念佛法门之间的关系出发,考查了早期禅宗与弥勒信仰的关系。文章认为,新兴的禅宗最初是以念佛三昧为出发点,称念弥勒乃其化人方便之一;禅宗之传衣说,实源自释迦通过迦叶而转授弥勒以僧伽梨之记载;无论从文献还是出土文物而观,净众保唐禅派皆崇奉弥勒。     

Tobacco use and health in young adulthood

In this prospective longitudinal study, the authors investigated the association between lifetime tobacco use and subsequent health problems by age 30. The authors interviewed a community group of 749 participants from upstate New York at mean ages of 14, 16, 22, and 27 years. Daily tobacco use during any of the time periods, as well as the number of periods of daily tobacco use, were significantly associated with increased risk for respiratory ailments, neurobehavioral and cognitive problems, and general malaise. The results suggested that daily tobacco use, either during childhood, adolescence, the early 20s, or a combination of those times, predicted health problems by age 30. Effective smoking prevention programs that begin in childhood are imperative to prevent the occurrence of later health problems.     

Distinction bias: misprediction and mischoice due to joint evaluation

This research identifies a new source of failure to make accurate affective predictions or to make experientially optimal choices. When people make predictions or choices, they are often in the joint evaluation (JE) mode; when people actually experience an event, they are often in the single evaluation (SE) mode. The "utility function" of an attribute can vary systematically between SE and JE. When people in JE make predictions or choices for events to be experienced in SE, they often resort to their JE preferences rather than their SE preferences and overpredict the difference that different values of an attribute (e.g., different salaries) will make to their happiness in SE. This overprediction is referred to as the distinction bias. The present research also specifies when the distinction bias occurs and when it does not. This research contributes to literatures on experienced utility, affective forecasting, and happiness.     

Thinking styles: university students' preferred teaching styles and their conceptions of effective teachers

In the present study, the author investigated the role of thinking styles in university students' preferences for teaching styles and their conceptions of effective teachers. Students (121 men and 134 women) from the University of Hong Kong responded to 3 self-report tests: the Thinking Styles Inventory-Revised (R. J. Sternberg, R. K. Wagner, & L-F. Zhang, 2003), the Preferred Thinking Styles in Teaching Inventory (L-F. Zhang, 2003c), and the Effective Teacher Inventory (L-F. Zhang, 2003b). Results indicated that even after age, gender, and academic discipline were controlled, particular thinking styles predisposed students to particular teaching styles. Moreover, as expected, students were open to more than just teaching styles that precisely matched their own thinking styles. Results also indicated that students' thinking styles made a difference in their conceptions of effective teachers. Discussions are focused on the study's contributions to both the style literature and the growing body of knowledge on characteristics of effective teachers.     

试论管仲人才思想中的民本因素--以《管子》为中心

民本思想是齐文化的重要组成部分,也是管仲施政思想的基石,其言论．行动中都展示着民本思想的精华。而体现管仲思想的《管子》一书,对人才思想有较系统的论述。本文试以管仲为例,以《管子》一书为中心,来探析其人才思想中的民本因素,即“任其所长,不任其所短”的人才原则,包括其产生原因、表现方式、对后世所带来的社会影响等。     

早期基督徒与素食

本文分析了<圣经>记载的上帝最初为人类安排的食物和洪水之后的食物,犹太教数位先知的言行,早期著名基督徒保罗、德尔图良、克莱门等人的教诲,参考了当代圣经学者的研究结论以及犹太教艾塞尼派经典的引证、分析,从而得出结论:早期的基督徒都是素食者.     

Nicotinic cholinergic synaptic mechanisms in the ventral tegmental area contribute to nicotine addiction

Tobacco use is a major health problem that is estimated to cause 4 million deaths a year worldwide. Nicotine is the main addictive component of tobacco. It acts as an agonist to activate and desensitize nicotinic acetylcholine receptors (nAChRs). A component of nicotine's addictive power is attributable to actions on the mesolimbic dopaminergic system, which serves a fundamental role in the acquisition of behaviors that are inappropriately reinforced by addictive drugs. Here we show that nicotine, in the same concentration and time ranges as obtained from tobacco, has three main actions that regulate the activity of midbrain dopamine (DA) neurons. Nicotine first activates and then desensitizes nAChRs on the DA neurons. This process directly excites the DA neurons for a short period of time before the nAChRs desensitize. Nicotine also enhances glutamatergic excitation and decreases GABAergic inhibition onto DA neurons. These events increase the probability for synaptic plasticity, such as long-term potentiation. The short-lived direct excitation of the DA neurons coupled with the enhanced glutamatergic afferent activity provides the presynaptic and postsynaptic coincidence necessary to initiate synaptic potentiation. In total, these synaptic events lead to a relatively long-lasting heightened activity of midbrain DA neurons. Consistent with other summarized studies, this work indicates that the synaptic changes normally associated with learning and memory can be influenced and commandeered during the nicotine addiction process.     

汉语转折复句的命题表征项目互换效应研究

采用句子一图画验证任务(sentence-picture verification task)探讨了汉语转折复句的命题表征项目互换效应。结果表明,汉语倒装转折复句的项目表达顺序为“(但是)B→虽然A”,命题表征中项目存在着互换的倾向,所形成的命题表征为“虽然A→但是B”。本研究结果初步表明,读者理解汉语转折复句可能是一个按照“虽然A(事实让步)→但是B(转折)”固定方向进行系列认知加工的过程。     

Preserved spatial memory over brief intervals in older adults

Two studies compared young and older adults' memory for location information after brief intervals. Experiment 1 found that accuracy of intentional spatial memory for individual locations was similar in young and older participants for set sizes of 3 and 6. Both groups also encoded individual locations in relation to the larger configuration of locations. Experiment 2 showed that like young adults, older adults' latency to respond to a test probe in a letter working memory task was negatively influenced by spatial information that was irrelevant to the task. This interference effect indicated preserved incidental memory for spatial information in older adults. Together, these data suggest that initial encoding of spatial information for relatively small numbers of items is largely preserved in healthy older adults and that representations of spatial information persist over short intervals.     

Improving fairness in coverage decisions: performance expectations for quality improvement

Patients and physicians often perceive the current health care system to be unfair, in part because of the ways in which coverage decisions appear to be made. To address this problem the Ethical Force Program, a collaborative effort to create quality improvement tools for ethics in health care, has developed five content areas specifying ethical criteria for fair health care benefits design and administration. Each content area includes concrete recommendations and measurable expectations for performance improvement, which can be used by those organizations involved in the design and administration of health benefits packages, such as purchasers, health plans, benefits consultants, and practitioner groups.
