Scholars committed to opportunities in psychological education: a training and mentoring program for future psychologists of color

ABSTRACT

Although strides towards inclusivity and racial equality have been made in graduate education, many barriers to graduate education remain for racial/ethnic minorities. In response, we created Scholars Committed to Opportunities in Psychological Education (SCOPE), a mentor-based program for racial/ethnic minority undergraduates. 63 racial/ethnic minority undergraduates completed the SCOPE curricula and pre- and post-program questionnaires regarding graduate school application knowledge, application confidence, stress, self-efficacy, and SCOPE program satisfaction. Mentors completed a training and questionnaires in one SCOPE cohort. Knowledge about the GRE, the application process, and application confidence increased, and stress decreased, following SCOPE. The result of this work is a portable mentoring program that can be used across disciplines and demographics to increase inclusivity and equality.     

Unity3D下构件化虚拟仪器功能实现方法

三维虚拟现实漫游仿真和虚拟仪器实验过程仿真是目前两种主要仿真手段,前者能够很好地模拟真实实验场景,后者则能更好地仿真实验细节。为了解决传统虚拟实验交互性弱、开发周期长等问题,提出了一种Unity3D下的构件化虚拟仪器功能实现方法。首先在Unity3D平台上开发多种标准化、可复用的虚拟仪器;然后将虚拟仪器引入虚拟现实场景中,并通过基于事件中心的观察者模式实现虚拟仪器的通信和数据流动;最后,依据构建的虚拟仪器开展典型机械工程测量实验。结果表明,与传统虚拟实验相比,该方法具有更好的真实性、交互性,同时构件化的思想缩短了开发周期。     

儿童焦虑与父母教养方式关系的调节变量研究

研究综合了来自中国大陆18570名3-12岁儿童的焦虑与父母教养方式相关的30项研究的数据,通过元分析的方法考查了二者相关的强度,并分析影响相关强度的因素。从总体上来说,儿童焦虑与父母教养方式存在弱相关;父母教养方式类型、儿童年龄、父母性别会对二者关系产生调节作用。建议在教养儿童过程中要采用正向的教养方式,要给予年幼儿童充分的独立自主的权利和自由,鼓励父亲参与教养,这有利于降低儿童的焦虑水平。     

The impact of alternative authentic assessment outcomes in Palestinian fourth grade math classrooms

Focusing on evaluating students’ performance in basic math classrooms, the researchers in this study examined the impact of alternative assessments on learning outcomes in fourth grade Palestinian classrooms. Representing a large sector of education in the Palestinian territories, fourth grade students were randomly selected to participate in the study in which they participated in various math instructional and assessment activities throughout multiple lessons and cycles. Alternative assessment approaches were used including student self- assessment, peer assessment, and teacher assessment in terms of three main achievement levels to measure the extent to which students learned the math concepts by recall and remembrance, ability to apply, and making inferences. Mixed Design ANOVA measures were used to analyze and interpret the results which showed significant trends and correlations across the four cycles of math instruction and indicated that alternative authentic assessment methods have had a positive impact on students’ learning and application of math. Implications for integrating authentic assessment measures as well as peer and self- assessments were drawn in light of the promising outcomes of augmenting student motivation and developing critical life-long skills.     

基于B/S结构的电子签到系统的设计与实现

B/S结构,即Browse/Server(浏览器/服务器)结构,是随着Internet技术的兴起,利用了不断成熟的WWW技术,结合浏览器的多种Script语言(VBScript、JavaScript…)和ActiveX技术,用浏览器就实现了强大的功能,是一种全新的软件系统构造技术。Active Server Pages(简称ASP)是一种包含了VBScript或JavaScript脚本程序代码的动态网页技术,浏览器浏览ASP网页时,IIS(Internet Infomtaion Server)就会根据请求生成相应的HTML代码,然后再返回给浏览器,浏览器端看到的就是动态生成的网页,ASP可以采用ADO(ActiveX Data Object)技术访问后台与数据库。在此基础上,利用ASP技术实现基于B/S结构的电子签到系统。

Polychlorinated dibenzo-p-dioxins and dibenzofurans in flue gas emissions from municipal solid waste incinerators in China

Polychlorinated dibenzo-p-dioxins and furans （PCDD/Fs） emissions in flue gas from two types of municipal solid waste incinerators （MSWIs） most commonly used in China were investigated in this study. The selected incinerators include two grate-type MSWIs： MSWI-A （350 t/d） and MSWI-B 050 t/d）, and two fluidized bed MSWIs： MSWI-C （400 t/d） and MSWI-D （400 t/d）, which are all equipped with semi-dry lime scrubber and bag filter except MSWI-D equipped with cyclone and wet scrubber （WS） as air pollutant control device （APCD）. Results indicated that the emission concentration and the international toxic equivalents （I-TEQs） of the PCDD/Fs from the stacks were in the range of 1.210-10.273 ng/Nm^3 and 0.019-0.201 ng I-TEQ/Nm^3, respectively. They were greatly lower than the emission regulation standard of PCDD/Fs in China （1.0 ng I-TEQ/Nm^3）. However, only the PCDD/Fs emission level from MSWI-C was below 0.1 ng I-TEQ/Nm^3. Although the homologue profiles were distinct, the contributions of the 2,3,7,8-subsituted congeners to the total I-TEQ were similar among all the investigated MSWIs. Two major 2,3,7,8-substituted congeners, 2,3,4,7,8-PeCDF and 1,2,3,7,8-PeCDD, account for 47% and 9% （average values） of the total I-TEQ values, respectively. The correlation between PCDD/Fs levels and composition of flue gas was also discussed.
