新中国成立六十多年特别是改革开放三十多年来,社会主义革命、建设和改革取得巨大成就的关键在于开创了一条既坚持科学社会主义的基本原则,又根据我国实际和时代特征赋予其鲜明的中国特色的"中国道路".社会主义核心价值体系正是在"中国道路"不断探索、发展和完善的过程中形成的,体现了中国特色社会主义道路的本质要求,在思想和实践中引领了"中国道路"的发展. 相似文献

本文立足于对索伦鄂温克人岁时仪式中火神祭祀仪式的田野调查资料,借鉴了范·杰内普和特纳的仪式研究理论及方法,从象征的角度分析了火神祭祀的仪式过程、仪式结构与秩序,从而描述仪式所表达的深层意义:有形世界与无形世界并非毫不相干,人也并不总在被动地接受神的安排,神秘甚至是危险的世界在仪式中变得可以接触。更为重要的是,对于仪式的参与者来说,一切行为都是可以解释的,而不是毫无理性地随意而为。 相似文献

The adenosine A(2A) receptor (A(2A)R) is highly enriched in the striatum where it is uniquely positioned to integrate dopaminergic, glutamatergic, and other signals to modulate cognition. Although previous studies support the hypothesis that A(2A)R inactivation can be pro-cognitive, analyses of A(2A)R's effects on cognitive functions have been restricted to a small subset of cognitive domains. Furthermore, the relative contribution of A(2A)Rs in distinct brain regions remains largely unknown. Here, we studied the regulation of multiple memory processes by brain region-specific populations of A(2A)Rs. Specifically, we evaluated the cognitive impacts of conditional A(2A)R deletion restricted to either the entire forebrain (i.e., cerebral cortex, hippocampus, and striatum, fb-A(2A)R KO) or to striatum alone (st-A(2A)R KO) in recognition memory, working memory, reference memory, and reversal learning. This comprehensive, comparative analysis showed for the first time that depletion of A(2A)R-dependent signaling in either the entire forebrain or striatum alone is associated with two specific phenotypes indicative of cognitive flexibility-enhanced working memory and enhanced reversal learning. These selective pro-cognitive phenotypes seemed largely attributed to inactivation of striatal A(2A)Rs as they were captured by A(2A)R deletion restricted to striatal neurons. Neither spatial reference memory acquisition nor spatial recognition memory were grossly affected, and no evidence for compensatory changes in striatal or cortical D(1), D(2), or A(1) receptor expression was found. This study provides the first direct demonstration that targeting striatal A(2A)Rs may be an effective, novel strategy to facilitate cognitive flexibility under normal and pathologic conditions. 相似文献

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality. 相似文献

Visual co-orientation with another's gaze direction (gaze following) may provide important information about the location of food, social interactions or predators. Gaze following has been shown in a variety of mammals, but only in few bird species, and has not been tested in precocial birds at all. It has been suggested that gaze following is an anti-predator behaviour, and in Common ravens (Corvus corax) and rooks (C. frugilegus), it emerges shortly after fledging, at a time when young birds leave the predator-safe nest. However, if gaze following is adaptive, the developmental pattern should differ between altricial and precocial birds. Greylag geese (Anser anser) are highly social birds with a precocial development. Goslings move and feed independently within 24 h post-hatching, and they are highly vulnerable to aerial predators. We therefore predicted that greylag geese are capable of gaze following and that they develop this skill already pre-fledging. We experimentally tested 19 hand-raised greylag goslings for their ability to follow a conspecific's gaze when they were between 10 days and 6 weeks old. In line with our predictions, first responses were already detectable in 10-day-old goslings. Our results therefore not only demonstrate that greylag geese follow the gaze of conspecifics into distant space, but that they also develop this ability much earlier than altricial birds. 相似文献

The Dutch Book Argument shows that an agent will lose surely in a gamble (a Dutch Book is made) if his degrees of belief do
not satisfy the laws of the probability. Yet a question arises here: What does the Dutch Book imply? This paper firstly argues
that there exists a utility function following Ramsey’s axioms. And then, it explicates the properties of the utility function
and degree of belief respectively. The properties show that coherence in partial beliefs for Subjective Bayesianism means
that the degree of belief, representing a belief ordering, satisfies the laws of probability, and that coherence in preferences
means that the preferences are represented by expected utilities. A coherent belief ordering and a utility scale induce a
coherent preference ordering; a coherent preference ordering induces a coherent belief ordering which can be uniquely represented
by a degree-of-belief function. The preferences (values) and beliefs are both incoherent or disordered if a Dutch Book is
made. 相似文献

Research regarding prevention strategies for Hispanic youth stress the importance of family interventions because of the particular
importance of family as a protective factor within the Hispanic community. Starting in 1995, the Center for Substance Abuse
Prevention conducted the National Cross-Site Evaluation of High Risk Youth Programs, a 5-year drug and alcohol prevention
study with a sample of approximately 10,500 youth, including nearly 3,000 Hispanic youth. Youth were surveyed regarding their
alcohol use patterns and risk and protective factors, with several measures of family relationships, including family connectedness,
family supervision, and parental attitudes toward their child's alcohol use. Analyses indicate that family factors are highly
linked to alcohol use among Hispanics, particularly among Hispanic females. Longitudinal growth curve analyses indicate that
improving the connections that young Hispanic females have to their parents can have positive long-term effects on delaying
or reducing their alcohol use.
This evaluation was conducted under the direction of Dr. Soledad Sambrano, Ph.D. of the Center for Substance Abuse Prevention
under contract #2777-95-5002 with EMT Associates, Inc. and ORC Macro. The views expressed herein represent the opinions and
