标题:Among The Missing: Content On Lesbian And Gay People In Social Work Journals
摘要:在社会工作文献中,关于同性恋和同性恋者的问题几乎没有被提及.本研究考察了1988年至1997年间在四本主要社会工作期刊上发表的关于同性恋的文章内容.文章根据关注点被编码为hiv/aids与同性恋社区或其他与女同性恋者和男同性恋者有关的问题.文章还被编码为以客户为中心,以工作者为中心或宏观为中心.在77篇关于同性恋的文章中,三分之二集中于hiv/aids.大多数文章反映了对同性恋者的以问题为导向的观点;很少有文章涉及异性恋主义或环境干预.需要更多关注同性恋者和女同性恋者优势,异性恋主义条件及社会公正的文献.

摘要:PCT No. PCT/US94/10655 Sec. 371 Date Mar. 20, 1996 Sec. 102(e) Date Mar. 20, 1996 PCT Filed Sep. 20, 1994 PCT Pub. No. WO95/08529 PCT Pub. Date Mar. 30, 1995Chiral surfactants, methods for their synthesis and use, and apparatus designed to facilitate chiral separations using nucellar capillary electrophoresis is disclosed. A chiral surfactant having the general formula: is described, R1 is the hydrophobic tail, Y-A-X is the linker, the brackets define a chiral center, and the hydrophilic head group is Z. All the various components may potentiate the enantioselectivity of the chiral surfactant. The capillary electrophoresis (CE) system includes a narrow diameter capillary, a high voltage power supply, an electrolyte reservoir at each end of the capillary, a means for injecting a sample, and a detector. Chiral surfactants are dissolved in the electrolyte above their critical micelle concentration (cmc), resulting in the formation of chiral micelles. The electrolyte reservoirs and capillary tube are filled with the electrolyte. A sample containing a mixture of enantiomers is then injected into the capillary, and a high voltage potential is applied across the capillary. The sample components migrate through the capillary due to the influence of the applied electric field. An example separation of the four sereoisomers of aspartame is shown.
