澳大利亚政府制定和实施了许多不同的政策来处理土著人的问题。这些政策以对土著人殖民化开始,随后改变为对其排除,后又改为将其同化,最后以给予土著人自治权而结束。本论文介绍了土著人独特的文化;评述澳大利亚政府在不同时期对土著人采取的四种不同的政策,以及这些政策对土著人的影响;最后回顾土著人在争取平等权利过程中所做的努力并探究了他们现在所处的境况。 相似文献

5-Fluorouracil (5-FU) has a broad spectrum of anti-tumor activity, widely applied to the treatment of cancers. However, it is necessary to determine the plasma concentration of 5-FU in clinical practice due to its narrow therapeutic index. Therefore, a simple, economic and sensitive high-performance liquid chromatography (HPLC) method was developed and validated for the determination of 5-FU in human plasma. Ethyl acetate was chosen as extraction reagent. Chromatographic separation was performed on a Diamonsil C18 column (250 mm × 4.6 mm i.d., 5 μm) with the mobile phase consisting of methanol and 20 mmol/L ammonium formate using a linear gradient elution at a flow rate of 0.8 mL/min. 5-FU and 5-bromouracil (5-BU) were detected by UV detector at 265 nm. The calibration curve was linear over the concentration range of 5—500 ng/mL and the correlation coefficient was not less than 0.992 6 for all calibration curves. The intra- and inter-day precisions were less than 10.5% and 4.3%, respectively, and the accuracy was within ±3.7%. The recovery at all concentration levels was 80.1±8.6%. 5-FU was stable under possible conditions of storing and handling. This method is proved applicable to therapeutic drug monitoring and pharmacokinetic studies of 5-FU in human. 相似文献

禁用偶氮染料检测方法探讨 总被引:3,自引:0,他引:3
将固相萃取技术应用于禁用偶氮染料中代谢物苯胺类物质的检测。采用自制的大孔吸附树脂固相萃取小柱可以同时吸附水体中的苯胺类物质和其他常用染料。HPD系列大孔吸附树脂对苯胺类物质的吸附量大于对染料的吸附量,解脱性良好,适宜于做本方法的固定相。利用丙酮和乙醇2种溶剂的不同极性,将染料与苯胺类物质进行洗脱分离,解脱率较高,适宜做本方法的洗脱剂。通过紫外吸收光谱法和高效液相色谱法进行定性、定量检测,初步建立起一套快速、简单、实用的分离检测方法。 相似文献

Reducing fixed term exclusions (FTE) in primary schools is a difficult proposition. This research discusses how a partnership of primary schools developed more inclusive systems to support students previously given FTEs for disciplinary purposes. Longitudinal data from interviews and documentary sources trace the development of an approach amongst primary schools with previously high levels of FTE. The process of developing a model of transferred inclusion (TI) within the partnership led to schools changing practices around behaviour management, thus developing more inclusive systems. The paper elaborates on partnership work around the TI project that opened up discussion and questioning of practice around behaviour, leading to schools thinking about their systemic practice. The benefits of TI, therefore, were a prompt for development, rather than just an intervention to reduce exclusions. Changes in practice supported through the TI process lead to claims that substantive change would not have happened without the TI project. 相似文献

离子色谱已广泛应用于实验分析中,它逐步替代经典的化学分析方法.但离子色谱仪在调节和分析过程中还存在许多影响因素,这些因素如果消除不善,也可能导致实验的失败.本文对YIC-8型离子色谱分析仪在阴离子分析中出现的影响因素及其相应的消除方法进行了初步研究和探讨. 相似文献

德国证据使用禁止理论与美国非法证据排除规则作为当代世界两大法系主要法治国家在刑事证据排除规则方面的两种代表性理论,在两国的立法和司法实践方面都具有丰富的内涵并按照不同的原则形成了各自的例外。这种"原则加例外"的法律实践模式对于其他法治国家而言具有典型的"范式"意义,这种范式只有在切合各国法律传统和具体国情的基本框架内构建各自的刑事证据排除规则,才能从制度上保障刑事诉讼程序的公正高效运行。 相似文献

In this review, we propose a social ecological constraint model to study inclusion of overweight or obese students in physical education by integrating key concepts and assumptions from ecological constraint theory in motor development and social ecological models in health promotion and behavior. The social ecological constraint model proposes that constraints exist on five different levels and interact within and across levels to affect overweight students’ engagement, learning, and physical activity in physical education. This model can provide a theoretical framework to guide and organize research on the inclusion of overweight students. It can also guide teachers in manipulating these constraints to create a culture for inclusion and provide instruction to meet the needs of overweight or obese students. 相似文献

In the last few decades physical mobility has become one of the key elements of contemporary societies. This centrality of mobility also means the development of a new kind of social exclusion caused by the problems of living in a social context in which one has to be increasingly “on the move” to access goods and services. In this article, based on fieldwork conducted with 20 low-income family inhabitants of the city of Santiago, Chile, we study the role that mobile phone usage has in relation to physical mobility in the everyday lives of these individuals. Through an analysis of the pattern of usage and mobility of these devices, we arrive at the conclusion that rather than giving rise to an experience of constant mobility and “anytime–anywhere” availability, the individuals studied face limitations and exclusions that profoundly constrict the potential “mobility” afforded by these devices. 相似文献
