Juan José Ponce-Vázquez 《Slavery & abolition》2016,37(4):704-723
In the early seventeenth century, important socioeconomic changes in the Spanish colony of Hispaniola brought about substantial shifts in race relations between white residents and peoples of African descent, who were enslaved and free. As the plantation system declined precipitously, white members of the Spanish elite started envisioning new roles for enslaved laborers, which included enrolling these enslaved peoples in their own intrigues against other elites. This cooperation led people in bondage to carry out violent attacks and assassination plots against other members of the white colonial society. People of African descent took advantage of these collaborations as an opportunity to advance their own interests within the community. Nevertheless, people of African descent faced fierce and often violent backlash if they acted of their own accord. 相似文献

Urbanization has been considered as a major threat to biodiversity, making its ecology of increasing interest. Many urban ecology studies have been developed in a short time-scale, measuring real-time patterns. However, long-term studies are imperative to understand the responses of some species to the urbanization process. In this study, we aimed to assess the information provided by a recent one-year citywide bird survey when compared to a published ‘historical’ bird list of a neotropical city (Xalapa, Mexico) that compiles information of the past three decades, mainly from urban greenspaces. Specifically, we contrasted species richness values and assessed differences in species composition between both lists. We recorded 51 species in the one-year citywide survey, representing ~15 % of those reported in the historical list. Nonetheless, the upper-bound confidence interval of the citywide survey richness prediction represented ~66 %. Most of the species recorded in the one-year citywide survey are insectivores and granivores, a pattern that agrees with previous findings that underline the importance of insectivores as part of urban bird communities in the Neotropics. Although we used robust methods to compare our one-year citywide bird list and the historical list for the city of Xalapa, we acknowledge the limitations of comparing them. However, our results shed some light on the kind and type of information that one-year citywide surveys can provide and the importance of long-term studies for comprehending the processes involved in biodiversity changes within urban areas over time. Undoubtedly, establishing long-term citywide surveys sampling birds and other biodiversity groups will allow us to better understand the response of biodiversity to urbanization over time. 相似文献

Objectives: Metabolic syndrome (MtS) and kidney stone are two common aging diseases with male dominant. This is the first study regarding the potential impact of MtS and its components on kidney stone in aging Chinese population.Methods: A total of 694 males with a mean age of 55.6 years were enrolled. The definition of MtS was according to the modified criteria developed by the Bureau of Health Promotion in Taiwan. Subjects were classified as having a disease of kidney stones according to diagnosis by a physician with available medical records or evidence from ultrasonography judged by an investigator of urologist.Results: Using age-adjusted multivariate logistic regression analysis, our results showed that subjects with kidney stone had significantly higher prevalence of MtS (p?=?0.04, OR?=?1.74, 95% CI: 1.0 1–3.00). The presence of MtS had significant correlation with kidney stone (p?=?0.01, OR?=?1.83, 95% CI: 1.1 4–2.93), which were associated with the increment of MtS components (p?0.01). After adjusting for age and testosterone level, abnormal blood pressure (BP) was the most significantly independent component of MtS for kidney stone among the MtS components (p?0.01, OR?=?2.81, 95% CI: 1.46–5.39).Conclusions: In aging Taiwanese males, the presence of MtS and its components are strongly associated with kidney stone. Abnormal BP is the most significant risk component of MtS for kidney stone. 相似文献

行为主义的学习理论提倡学习外语应如同母语般的直接理解和使用,完全逾越翻译这一过程。而基于认知主义和建构主义的二语习得理论,则认为外语学习者应充分利用母语知识来认知和建构外语技能。其实翻译活动应为一种外语学习策略,它不仅可以当作一种认知、记忆、情感、社交和补偿学习策略,同时也能促进词汇、阅读、写作等外语技能的发展,并对不同程度的学习者起到积极的促进作用。 相似文献

高校团员数量占学生总数的95%以上,团工作的优劣,团员表现的好坏直接影响着学校的整体工作.当前在全团开展增强团员意识主题教育活动,是共青团加强自身建设的一项重大战略举措.构建团员意识教育的长效机制,有利于长期深入广泛地开展团员意识教育工作,要从思想教育、组织建设、团务管理和"党建带团建"等方面去考虑. 相似文献

“人肉搜索”的法理思考 总被引:1,自引:0,他引:1
"人肉搜索"作为一种网络新兴事物与现象,根据其对象和涉及事件类型的不同,可分为公众人物涉公事件型、非公众人物涉公事件型、公众人物涉私事件型和非公众人物涉私事件型四种类型.从法律角度而言,四类"人肉搜索"对个人隐私的侵入程度,呈依次递增趋势.同时,"人肉搜索"事件中涉及的网络信息发布者、网络信息传播者、网站三方,各主体责任也有所不同. 相似文献
