Age-related changes of arachnoid foveae have been described, but objective, quantitative analyses are lacking. A new quantitative method is presented for estimation of change in total volume of arachnoid foveae with age. The pilot sample consisted of nine skulls from the Palmer Anatomy Laboratory. Arachnoid foveae were filled with sand, which was extracted using a vacuum pump. Mass was determined with an analytical balance and converted to volume. A reliability analysis was performed using intraclass correlation coefficients. The method was found to be highly reliable (intraobserver ICC = 0.9935, interobserver ICC = 0.9878). The relationship between total volume and age was then examined in a sample of 63 males of accurately known age from the Hamann-Todd collection. Linear regression analysis revealed no statistically significant relationship between total volume and age, or foveae frequency and age (alpha = 0.05). Development of arachnoid foveae may be influenced by health factors, which could limit its usefulness in aging. 相似文献

ABSTRACT Pupavac examines the rise of linguistic human rights advocacy and its approach in a case study of language politics in the post-Yugoslav states. A core concern of contemporary linguistic rights advocacy has been to tackle ethnically based discrimination and promote ethnic diversity. It does not only seek to prevent states from discriminating against those who speak minority languages. It expects states to take positive steps to preserve their diversity of languages. However, strategies affirming distinct linguistic identities may become complicit in perpetuating ethnic discrimination and ethnic divisions, as is evident in the language politics of the post-Yugoslav states. 相似文献

被伐树木形成的整体分离痕迹有其独特性,反映出特有的规律。本文介绍了在盗伐林木案件中,运用整体分离痕迹检验原理、方法,检验被伐树木分离面、分离缘的形态,检验其凸凹断茬特征、虫眼特征、裂纹特征、空心特征等特殊特征以及节子特征、年轮特征、木射线特征、树皮纹理特征等固有特征。特别是在两对应的锯断面之间木质完全缺失情况下,综合运用上述特征有针对性地检验,解决了部分被伐树木整体分离痕迹检验中分离痕迹能否作为同一认定证据、分离体是否原为同一整体的问题。文中所述对被伐树木上的特殊特征和固有特征的研究和运用,拓宽了被伐树木整体分离痕迹检验中特征标记的范围,为丰富被伐树木整体分离痕迹的检验方法提供了参考。 相似文献

This study empirically demonstrates the efficacy of a two-level Dirichlet-multinomial statistical model (the Multinomial system) for computing likelihood ratios (LR) for linguistic, textual evidence with multiple stylometric feature types with discrete values. The LRs are calculated separately for each feature type, namely, word, character and part of speech N-grams (N = 1,2,3), which are combined as overall LRs through logistic regression fusion. The Multinomial system’s performance is compared with that of a previously proposed system with the cosine distance (the Cosine system) using the same data (i.e., documents collated from 2160 authors). The experimental results show that: (1) the Multinomial system outperforms the Cosine system with the fused feature types by a log-LR cost of ca. 0.01 ~ 0.05 bits; and (2) the Multinomial system is more advantageous in performance with longer documents than the Cosine system. Although the Cosine system is more robust overall against the sampling variability arising from the number of authors included in the reference and calibration databases, the Multinomial system can achieve reasonable stability in performance; for example, the standard deviation value of the log-LR cost becomes lower than 0.01 (10 random samplings of authors for the reference and calibration databases) with 60 or more authors in each database. 相似文献

清代中晚期的北京,流行着一种语言通俗、七言四句的诗体——竹枝词。这些通俗诗,描述了清代北京的风土民情,记述了清代北京的生活时尚,表现了清王廷由盛而衰的历史变迁。作为非物质文化遗产,成为那个特定时代的文化标记,为我们提供了解读帝都末期城市生活状貌的文本,具有独特的认知价值和审美价值。 相似文献
