人们何以能够“舍生取义”?基于保护性价值观认知神经机制的解释

保护性价值观是一种拒绝与其他任何价值相互交易, 尤其拒绝与经济价值进行交易的观念。近些年来的认知神经科学研究证据表明, 人们之所以可以为了坚守保护性价值观, 表现出“舍生取义”的行为(如对抗利益诱惑甚至放弃生命), 一方面在于保护性价值观是以一种道义主义的绝对规则方式进行表征和建构的, 这使得人们较少进行利弊权衡; 另一方面, 由于保护性价值观与自我和道德认同过程紧密相关, 使得其被主观赋予了最高价值。未来研究中, 可以在借鉴保护性价值观的研究范式基础上, 开展对中国人核心价值观的实证研究探讨, 关注其文化差异问题, 并进行正确价值观的干预和正确引导的应用实践研究。     

Defensive aggression in terns: Effect of species,density, and isolation

Defensive aggression was examined in seven species of terns during the hatching period when young are most vulnerable and adults most responsive. Aggression toward an unfamiliar person varied with respect to species, flush distance, approach distance, number of birds overhead and diving, and number of dives per 2 min for all birds and the nest owner. Defensive aggression involved birds circling over and diving at the experimenter. Generally, flush distance was negatively correlated with nest density, while the number of birds diving was positively correlated with the nest density. The number of birds diving was positively related to the number of dives, dives by the owner, and the number overhead.     

空巢老人心理健康的现状及研究述评

空巢老人的心理健康引起了国内外研究者们的高度关注,逐渐成为一个热点课题.在综合国内外有关空巢老人心理健康的研究文献后发现,目前,学界对空巢老人的界定并不统一;从其心理健康现状来看,空巢综合症是空巢老人各种身心症状的主要体现,主要受社会支持、性别、婚姻状况、经济收入以及其他一些社会人口学因素的影响.虽然对空巢老人心理健康的研究已取得一些成就,但仍存在一些尚待解决的问题,未来研究应从统一空巢老人的涵义,完善研究方法,深入对其自身内部心理因素的探讨及加强跨文化的比较与借鉴等方面来开展.     

Psychological Hardiness and Adjustment to Life Events in Adulthood

Data were collected from 88 persons who had lost their jobs and 227 persons whose youngest child had left home to explore the impact of psychological hardiness on personal distress, adjustment, and coping strategies. Analyses controlling for numerous sociodemographic factors as well as NEO Neuroticism and Extroversion suggested that the interaction between overall hardiness and the experience of differential life events influenced the use of planful problem solving and positive reappraisal as coping mechanisms, as well as influencing levels of positive affect. In addition, a main effect for overall hardiness on several coping strategies, positive affect, and life satisfaction was obtained. Findings also suggested that job loss was a more stressful experience for adults in this study than was the empty nest. These data indicate that hardiness may mediate responses to life events that differ in terms of their predictability and anticipatory nature.     

High maternal aggression in dwarf hamsters (Phodopus campbelli and P. sungorus)

The defense of offspring, termed maternal aggression, is a highly conserved behavior in mammals, including rodents. This study examined relative levels of maternal aggression in two closely related dwarf hamster species, Phodopus campbelli and P. sungorus, that normally inhabit high latitude, boreal environments. When tested with first litters and with the breeder male remaining with the female (for P. campbelli the male is necessary for successful rearing of offspring), both species exhibited high levels of maternal aggression with average duration of aggressive behavior>80 sec for a 10 min test. For P. sungorus, males are not required to rear offspring. P. sungorus females with either one or multiple litters (singly housed after impregnation) exhibited significantly higher levels of aggression (>300 sec) relative to females co‐housed with the sires. In terms of species differences in attack style, P. campbelli exhibited a boxing or clawing strategy for ～50% of total attack time, but for P. sungorus, this form of attack occurred<5% of the time. For P. sungorus, attacks to the vulnerable belly and flank constituted>90% of all attacks, but these regions were attacked ～50% of the time for P. campbelli. A survey of levels of maternal aggression of rodents in other genera suggests that maternal aggression in Phodopus is at the high end of the spectrum. Results of this study suggest that the presence of the breeder male may actually suppress aggression in P. sungorus. This fact, as well as its high level of aggression and its distant relationship to mice and rats, suggest P. sungorus as a possible model for future studies on the neurobiological basis of maternal aggression. The relationship between the high rates of maternal aggression and life history strategy in Phodopus is discussed. Aggr. Behav. 00:000–000, 2005. © 2005 Wiley‐Liss, Inc.     

Defensive aggression in terns: Discrimination and response to individual researchers

The defensive responses of roseate terns (Sterna dougallii) were studied during the middle of the breeding season when all reproductive stages (incubation, chick-hatching, chick-rearing) were represented, to determine the factors affecting levels of nest defense and whether terns responded differently towards a familiar versus an unfamiliar researcher. Defensive aggression generally varied as a function of researcher identity, time of day, section or location in the colony and nest density. These variables explained from 60 to 66% of the variation in defensive aggression. More terns mobbed one researcher with more dive attacks than the other researcher. Terns were more aggressive in areas where the chicks had just hatched and were most vulnerable. © 1993 Wiley-Liss, Inc.     

城市“空巢”家庭特征分析

在城市化进程中,家庭空巢化正在成为一个热点问题。空巢老人是老年人中有独特需要的群体,极易产生各种身心问题。影响家庭空巢的因素很多,既有来自人口内部结构的因素．也有来自观念、社会、经济等方面的原因,并且在人口、经济、生理、休闲方式上有着独特的特征。空巢家庭的养老问题有着很大风险,因此养老模式的探讨也是一个值得关注的问题。     

Environmental representations of local communities' spokespersons in protected areas

Despite the popularization of the environmental discourse, rural environmental belief‐systems should not be viewed as homogenous. Focusing on the largest protected area in Greece, we examined heterogeneity in local environmental views. Local spokespersons elicited word associations to two stimulus terms, namely, ‘environmentalists’ and ‘protected area’. Based on association categories for both terms, we identified two sample segments. ‘Naturalists’ appealed to a naturalistic image, which shaped the core compartment of their representations. On the other hand, ‘skeptics’ provided both environmentalist claims and critical accounts. Our findings revealed that the environmental discourse was widely diffused among local spokespersons. Issues of power and participation in decision‐making processes within protected areas are discussed. For instance, dimensions of power and legitimacy were reflected in the frequency of association categories and their allocation among sample segments. Specifically, environmentalist accounts were overtly expressed by both ‘naturalists’ and skeptics, while a more socially, politically and critically inclined view was revealed by a small percentage of associations that were all elicited by ‘skeptics’. We conclude that appreciating the heterogeneity of rural environmental views can reinforce the democratic mandate in environmental policy‐making. Copyright © 2009 John Wiley & Sons, Ltd.     

知情同意与保护性医疗制度的思考

为了提高医务人员尊重患者知情同意权的法律意识和建立人文医疗的服务理念,促进医学伦理和医事法律建设的进程,对医疗活动中如何理解和落实知情同意与保护性医疗制度等问题进行了比较分析。目前,在如何调节知情同意与保护性医疗的矛盾方面缺乏明确的法律依据,因此,尊重患者的合法权益不仅体现医德和对生命的尊重,同时对于人文医疗与医患和谐有着积极的促进作用。
