Latino students are significantly underrepresented in higher education. As the largest and fastest growing racial/ethnic population in the US, this is cause for national concern. Additionally, this rapid population growth is a call for community and school leaders from underserved communities to assess their service areas and focus on interventions to increase the college-going rates of youth. Maywood is a city located in Southeast Los Angeles. Like many other urban areas, Maywood’s largely Latino population is underrepresented in higher education. This research focused on interviewing Maywood’s community and school leaders (n = 24) to gain insight into their perceptions of their role and responsibility to address issues surrounding their community’s low levels of educational attainment. A key theme emerged revealing that leaders understand their community’s educational issues but do not see their role as leaders to directly address this issue to build a college-going culture. Implications for practice in strengthening community partnerships and developing a college-going culture are provided and a series of recommendations for the creation of a college-going culture are discussed. 相似文献

Family economic status is generally considered to be an important factor associated with students’ educational outcomes. However,
to evaluate the strength of this contention, it is important to first have appropriate measures of family economic status.
Measuring the economic status of Vietnamese people has been particularly difficult as the respondents have not been able to
report accurately on their income. This has been compounded in rural populations, because of the relative economic homogeneity
of communities. This study constructed, calibrated and validated a set of items to form a measure of economic status of students’
families in rural Vietnam. 相似文献

In this article, I draw on poststructuralist work on "citationality" to elucidate an urban high school's student culture and intervention efforts with regard to LGBQ issues. I contend that the language, ideas and practices of LGBQ issues and awareness among students and staff "cite" or draw on broader (and often competing) discourses of normalcy, sexuality, and/or "good teaching." I discuss how the citational process makes it difficult to bring about change, as well as the possibilities for bringing about change. The significance of this article is the way it explicates the discourses used to articulate and describe LGBQ people, issues, and intervention efforts; and how these discourses may hinder efforts to create LGBQ support and awareness in schools. 相似文献

The integration of nanomaterials such as carbon nanotubes (CNTs) into microsystems is highly desirable, in order to make use of the unique nanomaterial properties in real devices. However, the CNTtomicrosystem integration is challenging to implement in a manufacturable, cost effective industrial process. This paper presents our work towards a process for making complete, integrated CMOS / MEMS systems with integrated CNT. We demonstrate the feasibility of the process, using roomtemperature process ing, lowcost equipment and consumables, and electrical control with automation possibilities. CNTs are directly integrated at the desired positions in the Si microsystem, forming closed Si / CNT / Si circuits. We explore different designs with the aim to obtain uniform and welldefined CNT synthesis conditions, and show that simplified designs can perform comparably to more complex ones. The Si / CNT / Si circuits obtained can show rectifying (Schottky like) or nearohmic behavior. Gas sensing possibilities are demonstrated, indicating the possibility of monitoring aging/ fermenting of food. Functionalization of CNTs is demon strated, using thermal evaporation of Sn and Pd, opening for selective and sensitive sensors for various gases and ana lytes. Detailed microscopic characterization of the obtained CNTs are presented. 相似文献

In this paper, we present a low cost and equipment-free blood filtration device capable of producing plasma from blood samples with mL-scale capacity and demonstrate its clinical application for hepatitis B diagnosis. We report the results of in-field testing of the device with 0.8–1 ml of undiluted, anticoagulated human whole blood samples from patients at the National Hospital for Tropical Diseases in Hanoi, Vietnam. Blood cell counts demonstrate that the device is capable of filtering out 99.9% of red and 96.9% of white blood cells, and the plasma collected from the device contains lower red blood cell counts than plasma obtained from a centrifuge. Biochemistry and immunology testing establish the suitability of the device as a sample preparation unit for testing alanine transaminase (ALT), aspartate transaminase (AST), urea, hepatitis B “e” antigen (HBeAg), hepatitis B “e” antibody (HBe Ab), and hepatitis B surface antibody (HBs Ab). The device provides a simple and practical front-end sample processing method for point-of-care microfluidic diagnostics, enabling sufficient volumes for multiplexed downstream tests. 相似文献

This paper proposes a framework for the design of sparsely distributed output feedback discrete-time sliding mode control (ODSMC) for interconnected systems. The major target here is to develop an observer based discrete-time sliding mode controller employing a sparsely distributed control network structure in which local controllers exploit some other sub-systems’ information as well as its own local information. As the local controllers/observers have access to some other sub-systems’ states, the control performance will be improved and the applicability region will be widened compared to the decentralised structure. As the first step, a stability condition is derived for the overall closed-loop system obtained from applying ODSMC to the underlying interconnected system, by assuming a priori known structure for the control/observer network. The developed LMI based controller design scheme provides the possibility to employ different information patterns such as fully distributed, sparsely distributed and decentralised patterns. In the second step, we propose a methodology to identify a sparse control/observer network structure with the least possible number of communication links that satisfies the stability condition given in the first step. The boundedness of the obtained overall closed-loop system is analysed and a bound is derived for the augmented system state which includes the closed-loop system state and the switching function. 相似文献
