和谐家庭伦理建构思考

家庭伦理对家庭成员的思想、行为起着规范和制约的作用,规定着家庭成员之间各种不同的道德义务,又是衡量评价家庭成员言行是非、善恶的重要标准。加强家庭伦理建设,是加强社会主义道德建设的需要,是美满幸福生活的力量源泉。家庭和谐是社会和谐的重要组成部分,是社会和谐的基础,可以起到化解社会矛盾的作用。和谐的家庭伦理建设应注重传统与现代相统一、权利与义务相统一、自律与他律相统一。     

孟加拉国伊斯兰极端势力发展历史及其根源

传统的伊斯兰宗教文化、经济上的贫困落后、不成熟的民主政治环境下的不良政党斗争、吏治腐败,再加上国际伊斯兰原教旨主义思潮和"革命"的影响,独立后经过30多年的政局演变,孟加拉国最终成为极端主义孳生的温床。     

Can canines alone be used for age estimation in Chinese individuals when applying the Kvaal method?

Due to the secondary dentin formation, the dental pulp undergoes changes in shape throughout life. Based on this phenomenon, the Kvaal method has been applied to various populations for age estimation, and its usefulness has been verified. When applying the Kvaal method to Chinese subjects, we observed a relatively strong correlation between mandibular canines and age. This study notes the correlation between canines and chronological age and is the first to identify which canine is most closely related to chronological age. In addition, a new, simpler formula is determined based on canines according to Kvaal’s methodology. The radiographs of 360 individuals from northern China were selected, from which the widths and lengths of the pulp from four canines were measured according to the Kvaal method. Next, inter- and intra-observer reliabilities were analyzed in order to assess the repeatability of these measurements. The correlation between measurements and age was examined, and Chinese-specific age estimation formulae were derived. The results revealed that the ratios from the left maxillary canine exhibited the strongest correlation with age compared to the other canines, whereas the left mandibular canine showed the weakest correlation, which may contribute to the overall poor correlation of mandibular canines with age. What’s more, the formula derived from the left maxillary canine in this study displayed the highest coefficients of determination, and the formula derived from all canines showed the lowest residuals. Both of these formulae performed better than the Chinese-specific formula derived from six different types of teeth in our previous study, which had formerly possessed the highest coefficients of determination and the lowest residuals. Thus, we concluded that canines do play an important role in age estimation in the Chinese population, and the correlation between maxillary canines and chronological age is stronger than that of mandibular canines, although no distinct trend as to which side is better correlated with age was established. Going forward, we recommend the analysis of additional samples from different geographical regions and populations to further verify the importance of canines in age estimation.
