This qualitative study explored lived experiences and behavioral changes among 15 adolescent victims of natural disasters utilizing the behaviorism perspective. Volunteer adolescent victims participated in a semi-standardized open-end interview, and data were coded using pattern recognition, theme, and content analysis. Results identified that participants' most prevalent themes for behavioral changes were isolation, social withdrawal, increased arguments with family and friends, avoid relationships, and over-protectiveness. Prevalent themes for lived experiences were moving to a new home, changing schools, and mother or father lost job. The majority of the participants reported hurricanes as their natural disaster experience. In conclusion, adolescent victims reported multiple behavioral changes that were a result of a natural disaster such as hurricanes. Likewise, these victims reported facing many lived experiences after a natural disaster occurrence.  相似文献

自汉武帝采纳了董仲舒"罢黜百家,独尊儒术"以来,儒家思想成为二千多年来封建君主专制主义统治的指导思想。儒家思想有着极强的适应性和兼容性,在朝代的更替中,不断地充实和调整自己,使自己处于正统思想的位置。在这个适应与调整的过程中,往往会出现错位和混乱,西汉末年的新莽时期就属于这样的状态。汉末的动荡为王莽专权提供了机会,王莽没有抓住儒家统治思想的基本精神,将儒家经典中的"器"当作治世之道,"奉古改制"迅速走向灭亡。  相似文献

The Color Additives Scientific Review Panel considered whether there was information sufficient to perform a carcinogenic risk assessment on the colors D&C Red No. 19 (R-19), D&C Red No. 37 (R-37), D&C Orange No. 17 (O-17), D&C Red No. 9 (R-9), D&C Red No. 8 (R-8) and FD&C Red No. 3 (R-3) and to evaluate the assessments sent to FDA as part of the petitions for use of the colors for drug and external uses by the Cosmetic, Toiletry and Fragrance Association (CTFA). There is a lack of human data concerning the colors for making a human health assessment, so the assessments are based upon the extrapolation of animal data. The risk assessments are determined for exposure to single chemicals. Excluded from consideration are possible effects from exposure to multiple chemicals, such as co-carcinogenesis, promotion, synergism, antagonism, etc. In the light of recent efforts in establishing a consensus in risk assessment, the Panel has determined that the CTFA assessments for R-10, O-17, and R-9 are consistent with present acceptable usages, although it questions some of the assumptions used in the assessments. The Panel identified a number of general assumptions made, and discusses their validity, their impact on total uncertainty, and the potential options to address the gaps in understanding that necessitate the assumption. The Panel also derived revised risk estimates using more "reasonable" assumptions than "worst-case" situations, for 90th percentile and average exposure. For those assumptions that are easily quantifiable, the Panel's estimates are less than an order of magnitude lower than the CTFA risk estimates, indicating that the underestimates and overestimates of the CTFA risk estimates tend to balance each other. The impact of most of the assumptions is not quantifiable. The assessment for R-3 is complicated by the fact that there is no good skin penetrance study for this color. It was assumed that the penetrance is similar to that of another water-soluble xanthene color, R-19. It is expected that the absorption of the color is not likely to exceed that of the smaller molecule, R-19. Therefore, the risk estimates are similar to the CTFA estimates, but with different reasoning. The estimates for R-8 and R-37 are different from the others in that there is a lack of any exposure or toxicological information on these colors.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

人类中心主义既不是人类专制主义,也不是人类沙文主义,全球生态危机是"生态帝国主义"以及社会经济制度和管理体制的缺失所使然。不是人类中心主义造成了全球生态危机,而是全球生态危机造成了人类中心主义的灾难。所以,人类中心主义应该成为批判的主体,而不是批判的客体。  相似文献

传统生产力概念强调生产力是人类征服自然界的能力,当代环境危机是人类"对自然界的征服"这一信念发展到极端的产物.因此,人类理当调整其传统生产力观念,将人类保护自然的能力纳入生产力体系之中,使社会-自然系统趋于优化进化.  相似文献

ABSTRACT

Brain drain, the exodus of highly skilled professionals, has a strong connection with Human Resource Development (HRD), as these experts are human capital for organizations, communities, and nations. In today’s global economy, HRD practitioners and scholars need to keep abreast of what circumstances trigger the migration of talented workers around the world and the implications for HRD. This article describes the brain drain in Venezuela. The magnitude of the talent crisis is the result of a complex combination of poor policy implementation, mismanagement, corruption, and socio-economic and political conflict. This article exposes the current realities and the repercussions the exodus of talent has had on Venezuela and the decline of a country that was once among the world’s richest, but is now an impoverished nation.  相似文献

论我国企业的危机公关--以"特富龙"事件为例   总被引:1,自引:0,他引:1  
任何组织在成长过程中无一例外都会经历各种各样的危机.若无有效的快速反应和处理机制,一旦危机爆发,就只能仓促上阵,被动应对,如处理不当,殚精竭虑建设起来的组织形象就可能毁于一旦.因此,任何组织都应该而且必须重视危机公关处理.而杜邦公司"特富龙"事件处理方法无疑是个成功案例,值得我国企业学习和借鉴.  相似文献
