学校辅导与青少年身心发展压力应对

学校辅导工作,尤其是中、小学的辅导工作应对青少年身心发展方面的压力多予以关注。近年来,青少年在心理健康方面出现的诸多问题表明,许多心理行为问题的发生和危机事件的出现,都与青少年面临的生活压力有着密切关系。学校心理辅导工作应明确青少年心理行为问题发生的基本原因,在辅导过程中积极引导青少年健康成长,在心理健康教育课程中,有针对性地讲授有关生活压力缓解的知识和方法,以有效的策略帮助青少年顺利度过青春期难关。     

史前漆膜的分析鉴定技术研究

研究了漆膜分析的三种主要方法：裂解质谱,红外光谱,裂解色谱。通过大量实验比较了各种方法的适应性和可靠性,建立了以裂解色谱／富里叶红外光谱联用技术来鉴定漆膜,并对影响裂解反应的因素及色借条件进行了深入的研究,获得了可以重复,具有特征性的漆膜高分辨裂解色谱图,同时对裂解色谱图中主要组分作了定性鉴定,提高了裂解色谱法分析漆膜的可靠性。该方法具有灵敏度高,样品用量小,共存杂质影响小,操作简便等优点。应用核分析技术对河姆渡,良诸庙前遗址出土的二件红色涂料样品进行了鉴定。分析结果证实了河姆渡出土的红色涂料木碗上的涂料是我国至今发现的最早的生漆漆膜。

A slender new archaic beetle in Burmese amber (Coleoptera: Archostemata)

Jarzembowski, Edmund A., Wang, B. &; Zheng, D., October 2017. A slender new archaic beetle in Burmese amber (Coleoptera: Archostemata). Alcheringa 42, 110–114. ISSN 0311-5518.

A new archostematan beetle, Clessidromma palmeri gen. et sp. nov. (Insecta: Coleoptera) is described from mid-Cretaceous Burmese amber from northern Myanmar. It has a uniquely specialized body form for which a new stem tribe, Clessidromatini trib. nov., is proposed in the subfamily Ommatinae of the family Cupedidae sensu lato.

再论包山简“鲁阳公以楚师后城郑之岁”——兼谈楚简大事纪年的性质

包山简中的七条大事纪年早先被定在楚怀王时期,其中的"鲁阳公以楚师后城郑之岁"后来又被李学勤先生等考订为追记。清华简《系年》中有关于鲁阳公率楚军与三晋、郑国交战的记载,在楚声王至悼王年间,应与"鲁阳公以楚师后城郑之岁"一事相关。包山简中的另一纪年"齐客陈异致福于王之岁",可能是葛陵简中的"齐客陈豫贺王之岁"。同一批简牍中发现的楚简大事纪年未必是逐年相次的。     

Two‐regime Pattern in Human Mobility: Evidence from GPS Taxi Trajectory Data

Research on complex systems has identified various aggregate relationships in phenomena that describe these systems. Travel length has been characterized by negative power distributions. Controversy, however, exists over whether mobility patterns can be modeled in terms of a simple power law (Lévy flight model) or that more complicated power laws (exponential power law, truncated Pareto) are required. This study concentrates on two issues: testing the validity of exponential power laws and truncated Pareto distributions in urban systems to describe aggregate mobility patterns, and examining differences in mobility patterns for different travel purposes. The article describes the results of an analysis of Global Positioning System (GPS) taxi trajectory data, collected in Guangzhou, China, to identify mobility patterns in the city. The least squares statistic is used to estimate the parameters of the distribution functions. Results suggest that a fusion of functions, based on an exponential power law and a truncated Pareto distribution, represents the travel time distribution best. Moreover, the findings of this study indicate different mobility patterns to exist for different travel purposes.     

从“归纳”到“解释”:汉唐考古研究的趋势

政治史取向和类型学方法在保证汉唐考古取得很大成绩的同时,也制约了汉唐考古的研究范围、理论建设,并影响到汉唐考古研究者的知识结构和思维方式。新出土资料的减少迫使汉唐考古改变"能源型"发展模式,其他人文学科的发展则为汉唐考古向"技术型"转变带来机遇。汉唐考古研究者的主要工作从归纳总结考古资料,转变为以历史文献为基础,借鉴其他人文学科的方法论,对汉唐考古材料的内涵和意义进行解释,是汉唐考古研究的发展趋势。     

Does clean air increase the demand for the consumer city? Evidence from Beijing

Cities offer a large menu of possible employment and leisure opportunities. The gains from such consumer city leisure are likely to be lower on more polluted days. We study the association between daily consumption activity and outdoor air pollution in China and find evidence in favor of the hypothesis that clean air and leaving one's home for leisure trips are complements. Given the high levels of air pollution in cities in the developing world, regulation induced improvement in environmental quality is likely to further stimulate demand for the consumer city.     

二战后匈牙利的通货膨胀与巨额纸币

特大面值的纸币往往是恶性通货膨胀,特别是大规模战争所导致的通货膨胀的产物,意味着社会经济生活的崩溃和人民生活水平的恶化。由于其面值巨大,社会流通环境恶劣,一般流通期也十分短暂。这些特点使其成为普通收藏者和钱币学者收藏研究的热点,除了面值巨大的奇特之处外,我们更能通过它们透视那些动荡的岁月。
