Mental health care for foster children in California

This paper reports on a study conducted to assess the health care needs of foster children in California. To evaluate foster children's mental health problems and the services provided to meet them, 154 program administrators, social workers, foster parents, and health care providers were interviewed in 14 counties. Foster parents and social workers were interviewed in groups, and foster parents and administrators also completed questionnaires. We found that although all counties care immediately for children who are injured, abused, or ill, only one county performs routine mental health evaluations of all children, and in most counties less than a third of children ever receive such evaluations. Informants identified mental health problems as more severe than medical problems in this population, and they identified four major barriers to access to appropriate therapy. Recommendations are that all children should receive comprehensive mental health evaluations, and procedures for immediate and ongoing care with consistent providers who are sensitive to foster children's needs should be included in case management plans, and covered by improved payment mechanisms. Additionally, communication, coordination and joint planning should be instituted among relevant agencies to address foster children's needs, and increased resources and training should be directed towards social service agencies and foster parents.     

Perpetrators and their acts: data from 365 adults molested as children

Intake interviews were analyzed from 365 adults molested as children (AMACs). The AMACs were entering treatment at the Child Sexual Abuse Treatment Program (San Jose, CA). This study presents data on the relationship of the perpetrator to the victim, and whether most molestations include intercourse. The majority of the perpetrators (62%) were either biological fathers or father-surrogates. Ninety-nine percent of the perpetrators were known to the victim; 97% were male. As in past studies, fondling from the waist down was the most common type of molestation, occurring in 92% of the cases. Forty-four percent of cases included intercourse. The present findings are compared with past research and are discussed in the context of common misconceptions associated with child sexual abuse.     

Multimedia search capabilities of Chinese language search engines

This paper reports results from a study exploring the multimedia search functionality of Chinese language search engines. Web searching in Chinese (Mandarin) is a growing research area and a technical challenge for popular commercial Web search engines. Few studies have been conducted on Chinese language search engines. We investigate two research questions: which Chinese language search engines provide multimedia searching, and what multimedia search functionalities are available in Chinese language Web search engines. Specifically, we examine each Web search engine’s (1) features permitting Chinese language multimedia searches, (2) extent of search personalization and user control of multimedia search variables, and (3) the relationships between Web search engines and their features in the Chinese context. Key findings show that Chinese language Web search engines offer limited multimedia search functionality, and general search engines provide a wider range of features than specialized multimedia search engines. Study results have implications for Chinese Web users, Website designers and Web search engine developers.     

科研项目间接费用补偿的激励作用研究

间接费用的补偿是科研项目经费管理的重要内容。本文从中国间接费用管理实践中存在的问题与现有研究的不足出发,首先分析了间接费用的定义与内涵,提出间接费用在政府科研资助、经费管理体系中的激励作用。其次,在委托代理理论框架下建立了间接费用补偿激励作用的分析模型,并提出影响其激励作用的关键因素。再次,基于国际实践的分析归纳形成两种典型的间接费用补偿模式,并分析其激励作用。最后,基于中国实践提出对科研项目间接费用补偿管理改革的政策建议。     

DNA microarray wet lab simulation brings genomics into the high school curriculum

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.     

Simplified method of designing FIR filter with controllable center frequency

A novel simplified method is presented to design FIR filter with controllable center frequency. The properties of transfer curves for all-phase filters are illustrated under 3 windowing conditions. By combining single-window all-phase filter design steps and double phase-shift combination, a series of design formulas for point-pass filter, notch filter, band-pass filter and band-stop filter are derived, thus the design computation complexity is greatly reduced. Experiments prove that the center frequency of all the filters can be accurately specified at arbitrary position by adjusting frequency parameters m and λ.

English Proficiency,Identity, Anxiety,and Intergroup Attitudes: US Americans’ Perceptions of Chinese

Guided by the Common Ingroup Identity Model and Berry’s acculturation framework, this study examined the roles that perceptions of language proficiency, cultural identity, and communication anxiety had on intergroup attitudes and stereotypes in the American–Chinese contact context. Serial mediation analyses with 10,000 bootstrap samples revealed that perceived English proficiency of a Chinese contact had significant indirect effects on affective and behavioral attitudes toward Chinese through American participants’ perceptions of their contact’s host and home culture identification and communication anxiety. Perceived English proficiency had an indirect effect only on positive stereotypes through the Chinese contact’s perceived identification with home culture.     

体力活动与癌症生存研究的10大问题

摘要：今天的美国有1 400万的癌症存活者,其中的很多存活者中都接受了多种治疗,包括手术、放疗、化疗、靶向治疗等。这些治疗能够延长生存时间,但同时也会带来很多急慢性的副作用,危害健康,影响生活质量。体力活动（PA）与癌症生存这一领域发展迅速,主要研究PA对癌症患者的影响。基于该领域的研究进展,提出了以下10大研究问题：1）PA能够降低癌症复发风险、和/或提高存活吗？2）PA能够影响癌症治疗决策、完成率、和/或患者对治疗的反应吗？3）癌症存活者的最佳运动处方是什么？4）静坐少动行为对癌症存活者有何影响？5）癌症存活者最有效的体力活动干预方案是什么？6）哪些癌症会影响病人对PA的反应？7）癌症存活者进行体力活动时需要注意的安全问题有哪些？8）哪些具体的癌症症状可以由PA解决？9）对于癌症晚期患者,体力活动还有何作用？10）如何将体力活动研究结果转化到临床和社区肿瘤实践中来？上述问题的回答至关重要,这不仅关系到体力活动和癌症存活这一研究领域的发展,更重要的是,能够为每年数百万新诊断为癌症的病人、正在接受癌症治疗的病人、治疗结束处于恢复中的病人或是那些正在与晚期癌症抗争的病人带来福音。
