The world set a goal in the Paris Agreement: to keep global warming within 1.5 degrees Celsius of preindustrial levels. The Intergovernmental Panel on Climate Change has explained why this is a valid goal. If global warming were to go higher than 1.5 degrees Celsius, this would jeopardize life on the planet with a potential multi-meter sea-level rise, the collapse of critical ecosystems, and the release of methane from thawing permafrost, possibly triggering runaway warming. Yet the world's current trajectory implies a catastrophic 2.7-degree- Celsius increase in global temperature. 相似文献

Suicide is a leading cause of death among adolescents, many of whom fail to disclose suicide concerns to adults who might help. This study examined patterns and predictors of help-seeking behavior among adolescents who seriously considered suicide in the past year. 2,737 students (50.9?% female, 46.9?% male; racial distribution 79.5?% Caucasian, 11.9?% Hispanic/Latino, and 3.6?% Black/African-American) from 12 high schools in rural/underserviced communities were surveyed to assess serious suicide ideation (SI) in the past year, disclosure of SI to adults and peers, attempts to get help, attitudes about help-seeking, perceptions of school engagement, and coping support. Help-seeking was defined as both disclosing SI to an adult and perceiving oneself as seeking help. The relationship between adolescents' help-seeking disclosure and (1) help-seeking attitudes and (2) perceptions of social resources was examined among suicidal help-seeking youth, suicidal non-help-seeking youth, and non-suicidal youth. Of the 381 (14?%) students reporting SI, only 23?% told an adult, 29?% sought adult help, and 15?% did both. Suicidal help-seekers were similar to non-suicidal peers on all measures of help-seeking attitudes and social environment perceptions. Positive attitudes about help-seeking from adults at school, perceptions that adults would respond to suicide concerns, willingness to overcome peer secrecy requests, and greater coping support and engagement with the school were associated with students' increased disclosure of SI and help-seeking. This study supports prevention strategies that change student norms, attitudes and social environments to promote help-seeking among adolescents with SI. Promising intervention targets include increasing students' perceptions of the availability and capability of adults to help them, and strengthening students' understanding of how existing resources can help them cope. 相似文献

The risk for depression increases as Hispanic youth acculturate to U.S. society. This association is stronger for Hispanic girls than boys. To better understand the influence of culture and family on depressive symptoms, we tested a process-oriented model of acculturation, cultural values, and family functioning. The data came from Project RED, which included 1,922 Hispanic students (53?% girls; 86?% were 14?years old; and 84?% were U.S. born) from Southern California. We used data from 9th to 11th grade to test the influence of acculturation-related experiences on depressive symptoms over time. Multi-group structural equation analysis suggested that both family conflict and cohesion were linked with depressive symptoms. Hispanic cultural values were associated with family cohesion and conflict but the strength and direction of these relationships varied across cultural values and gender. For girls and boys, familismo and respeto were associated with higher family cohesion and lower family conflict. Moreover, gender roles were linked with higher family cohesion in girls but not in boys. These results indicate that improving family functioning will be beneficial for boys' and girls' psychological well-being. This may be achieved by promoting familismo and respeto for boys and girls and by promoting traditional gender roles for girls. 相似文献

美国采纳严格产品责任的主要原因是:早期的法律不能给消费者提供充分的保护;调整保证的法律不是从消费者的角度出发的;美国的社会福利很大程度上不如其他西方国家。当今美国主要对于设计和信息性缺陷适用过失责任制度,严格产品制度仅适用于制造缺陷和非制造缺陷的销售者。欧洲和其他法域的严格产品制度远比美国严格。各种结构化和程序化的事务赋予美国公民更多诉至法院的机会。 相似文献

俄罗斯与越南的关系大约始于19世纪。当时虽然许多俄罗斯人到过越南访问,并写下有关越南的文章和书籍,但广大读者无从了解这些资料的来源。首先也许是因为还没有学者关心越南的研究以及对这些信息来源的价值作出评价。实际上,两国人民之间的各种关系始于20世纪20年代。当时有许多越南政治活动家,包括后来成为主席的胡志明,来到莫斯科学习和工作。在这个时期,他们第一次与各位东方学学者以及关心亚洲问题的实际活动家接触。在20世纪30年代,俄国最早出版的描述和概括地介绍越南的作品,大部分与越南经济社会状况有关。其中有… 相似文献

The number of the homeless people in Istanbul, one of the largest cities in the world, is at present unknown. There has been no previous study in Turkey on cases and causes of death occurring among these individuals. In this paper, documents and autopsy reports of the Mortuary Section of the Council of Forensic Medicine, Istanbul, covering the period January 1st, 1991-December 31st, 1995, were reviewed. We established that there were 126 cases of death among homeless individuals in Istanbul during this period, 120 of them being males (95%), four (3%) females, and two (2%) transsexuals. Ninety-four corpses were found outdoors, 32 indoors. No personal documents, such as identity cards, were found in 110 individuals (87%), whereas only 16 individuals could be identified. Most deaths occurred in the age group of 41-50 years. One hundred and three of the cases (82%) died in the cold season between October and April. The deaths of 98 cases were attributable to natural causes, whereas the remaining 28 cases died from unnatural causes. Respiratory tract diseases occupied the first rank among cases of death from natural causes (44%). Alcohol abuse and other infections were further striking factors contributing to the fatal outcome. This is the first retrospective study on this topic in Turkey. However, more detailed and anterospectively programmed studies on this subject, a growing social problem, should be carried out. 相似文献
