The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (Mage = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes. 相似文献

This paper discusses three separate educational projects which involved students working side-by-side with homicide investigators in an effort to conduct cold case investigations. Each project resulted in two different products, one for agency use and the other for public consumption. The cold case investigative reports produced for each case became part of the investigative file and are confidential documents. The video PSAs were for public consumption and were designed to provide additional exposure to the cases with the hope of generating productive tips. Each project was carried in collaboration with local Crime Stoppers programs, law enforcement agencies, and coroner’s offices. 相似文献

Trade in Australian education services has expanded rapidly over recent years. The sector is the third largest exporter of
Australian services. In 2001–2002, exports of education were about $A 4.2 billion. Government assistance to the sector includes
export market development, regulation of education standards, and funding education activities; university research and development,
for example. This paper examines the case for further government intervention in the export of education, and the appropriate
forms of assistance if further government intervention is justified. The paper predominately focuses on assisting higher education
exports because this activity dominates education exports. 相似文献

This study compared the performance of children with reading disability (RD) and normal reading achievement (NRA) on tasks
of serial rapid naming, verbal fluency, letter-based word retrieval, and articulatory speed. The groups, composed of children
at two discrete age levels, one younger and one older, were matched for age, gender, and neighborhood school. Analyses of
the on-line measurement of the children’s serial rapid naming indicated that the children with RD had significantly larger
reaction times and production durations than their NRA peers despite similar levels of accuracy. They also performed significantly
worse on the categorical verbal fluency task, the letter-based word retrieval task, and the test of articulatory speed. The
findings suggest that both access and post-access processes, such as oral-motor inefficiency that extends the duration of
word production, may be implicated in the slower serial rapid naming that has typified many samples of children with RD.

ABSTRACT Cities in the United States and across the world have experienced gentrification at the same time as school choice policies have become more popular. This research examines the relationship between gentrification and charter schooling, seeking to understand how together they affect demographic composition of schools across Washington, DC. This study uses geographic information systems (GIS) mapping and statistical techniques to show that gentrified neighborhoods are more likely to have charter schools. Additionally, the demographic compositions of charter schools and traditional public schools differ depending on the gentrification classification of the census tract in which the schools are located. While a handful of diverse charter schools exist in gentrified neighborhoods and some diverse public schools exist in traditionally affluent neighborhoods, schools in Washington, DC remain racially and economically isolated overall. 相似文献
