养成训练:未成年公民品德塑造的新路径

重灌输轻养成、重理论教育轻行为训练是青少年道德建设成效不高的重要原因,而养成训练则被证明是未成年公民道德素质生成的有效路径.这是由品德生成的客观规律、未成年人身心发展的特点以及体验教育、实践育人的任务决定的.要切实提高道德行为习惯养成的实际效果,德目指标应易记易循,行为准则须明确具体;活动方案设计应贴紧未成年人实际,训练活动要注重可操作性,强化情感体验环节,抓好"小处"、"小事",注意训练活动的持续性和家校(园)之间的良性互动,不断巩固养成成果.实践证明,从基本道德行为习惯养成训练入手正是促进未成年人道德建设取得实效的关键所在.     

杜绝科研工作中的失范行为，捍卫科学殿堂的圣洁性

不规范何以立,不规范难创新,默顿提出普遍性、公有性、无私利性和有条理的怀疑性构成了现代科学规范,科研失范行为一般指科研工作者在从事科研工作中为了实现自己的利益目标而违背科学界和学术界所公认的科学研究道德规范的行为,本文对各种科研示范行为进行分类,从政治、经济、体制等方面深度分析了科研失范的诱发原因,并有针对性的提出若干防范对策,从而捍卫科学殿堂的圣洁性。

基督教影响下的家庭观和婚姻观研究——以生活在中国境内的亚洲人为研究对象

在世界范围内,信仰基督宗教的人数大约在20亿人左右,而这20亿左右的人当中,亚洲占3亿多,其中主要分布在东亚和东南亚这些地区。近年来,随着基督教在亚洲传播速度的加快,亚洲范围内信仰基督宗教的人数预计在2025年时将会增加到5亿人。随着基督教在亚洲的迅速发展,我们可以预计在未来基督教将会在更大的层面上影响亚洲人的生活．尤其是在文化和价值判断上。随着近年来社会对于家庭问题的不断关注．家庭观念成为了研究的热点。所以我们设计了这次调查,以期望能够解读在现代社会中基督教对于人们家庭观念和婚姻观念的影响。     

To have and to be: towards the social representation of quality of life in China

This study explores the social representation of quality of life (QOL) in the Chinese socio‐cultural context. The data were collected by 16 open‐ended individual interviews. The study shows that the social representation of QOL embedded deeply in the collective memory of Chinese society is generated from, and organized around, the central thema of ‘having’/‘being’. ‘Having’ and ‘being’ are both antinomic and dialogically interdependent. ‘Having’ gives priority to how subject instrumentalizes object as resources to be possessed and consumed. It is manifested in the possessions of money, food, housing and car. The possessions are not only simply the material things but also the objects of symbolic significance. ‘Being’ prioritizes the authentic relationship between subject and object. It is manifested in rootedness, connectedness, participation and freedom. These provide a sense of belonging, commitment, direction and purpose and involve the establishment and maintenance of the union between the self and others, and between the individual and the outside world. On the other hand, neither ‘having’ nor ‘being’ exists in its pure form. Rather, they co‐exist dynamically, in rival or complementary ways, and each calls the possibility of the other into play. It is the synthesis of opposites between ‘having’ and ‘being’ that the social representation of QOL is generated and structured. Copyright © 2007 John Wiley & Sons, Ltd.     

Visual pattern memory requires foraging function in the central complex of Drosophila

The role of the foraging (for) gene, which encodes a cyclic guanosine-3',5'-monophosphate (cGMP)-dependent protein kinase (PKG), in food-search behavior in Drosophila has been intensively studied. However, its functions in other complex behaviors have not been well-characterized. Here, we show experimentally in Drosophila that the for gene is required in the operant visual learning paradigm. Visual pattern memory was normal in a natural variant rover (for(R)) but was impaired in another natural variant sitter (for(S)), which has a lower PKG level. Memory defects in for(S) flies could be rescued by either constitutive or adult-limited expression of for in the fan-shaped body. Interestingly, we showed that such rescue also occurred when for was expressed in the ellipsoid body. Additionally, expression of for in the fifth layer of the fan-shaped body restored sufficient memory for the pattern parameter "elevation" but not for "contour orientation," whereas expression of for in the ellipsoid body restored sufficient memory for both parameters. Our study defines a Drosophila model for further understanding the role of cGMP-PKG signaling in associative learning/memory and the neural circuit underlying this for-dependent visual pattern memory.     

Upregulation of hippocampal TrkB and synaptotagmin is involved in treadmill exercise-enhanced aversive memory in mice

Cognitive functions usually involve various synaptic proteins and neurotrophic factors in the hippocampus. However, whether treadmill exercise can improve learning and memory by upregulating some of these molecules remain unraveled. To address this question, male BALB/c mice were divided into control and exercise groups, the latter group went through 4 weeks of treadmill exercise training. At the end of exercise training period, they were either tested for passive avoidance (PA) performance or sacrificed for quantifying the hippocampal levels of brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB, the BDNF receptor), synaptotagmin (a Ca²⁺-dependent synaptic vesicle protein), and SNAP-25 (a presynaptic vesicular fusion protein). Our results showed that treadmill exercise training (1) increased the retention latency without affecting the fear acquisition in the PA test, (2) transiently increased the hippocampal BDNF level at 1, 2, and 4 h after the completion of exercise training, and (3) persistently increased the hippocampal protein levels of full-length TrkB, phosphorylated TrkB and synaptotagmin, but not truncated TrkB or SNAP-25. Moreover, the protein expression level of full-length TrkB or synaptotagmin was positively correlated with PA performance in mice. Finally, inhibition of TrkB signaling by K252a abolished the exercise-facilitated PA performance and upregulation of TrkB and synaptotagmin. Taken together, these data suggest that the upregulation of TrkB and synaptotagmin in the hippocampus contributes to the exercise-facilitated aversive memory.     

Acute ethanol ingestion impairs appetitive olfactory learning and odor discrimination in the honey bee

Invertebrates are valuable models for increasing our understanding of the effects of ethanol on the nervous system, but most studies on invertebrates and ethanol have focused on the effects of ethanol on locomotor behavior. In this work we investigate the influence of an acute dose of ethanol on appetitive olfactory learning in the honey bee (Apis mellifera), a model system for learning and memory. Adult worker honey bees were fed a range of doses (2.5%, 5%, 10%, or 25%) of ethanol and then conditioned to associate an odor with a sucrose reward using either a simple or differential conditioning paradigm. Consumption of ethanol before conditioning significantly reduced both the rate of acquisition and the asymptotic strength of the association. Honey bees also exhibited a dose dependent reduction in arousal/attention during conditioning. Consumption of ethanol after conditioning did not affect recall 24h later. The observed deficits in acquisition were not due to the affect of ethanol on gustatory sensitivity or motor function. However, honey bees given higher doses of ethanol had difficulty discriminating amongst different odors suggesting that ethanol consumption influences olfactory processing. Taken together, these results demonstrate that an acute dose of ethanol affects appetitive learning and olfactory perception in the honey bee.     

Personality traits and life satisfaction among online game players.

The DFC Intelligence predicts worldwide online game revenues will reach $9.8 billion by 2009, making online gaming a mainstream recreational activity. Understanding online game player personality traits is therefore important. This study researches the relationship between personality traits and life satisfaction in online game players. Taipei, Taiwan, is the study location, with questionnaire surveys conducted in cyber cafe shops. Multiple regression analysis studies the causal relationship between personality traits and life satisfaction in online game players. The result shows that neuroticism has significant negative influence on life satisfaction. Both openness and conscientiousness have significant positive influence on life satisfaction. Finally, implications for leisure practice and further research are discussed.
