Supporting practitioners in school-based evaluations of autism spectrum disorders

Students with autism spectrum disorder (ASD) have vastly different educational needs. Although some students with ASD may perform well across subjects within the general education classroom, other students with ASD may need more individualized support outside of the classroom. Historically, ASD assessments in schools have primarily focused on the measurement of cornerstone behaviors of ASD such as deficits in social communication and restricted or repetitive behaviors while underestimating the focus of academic skills even though both factors are required in the evaluation process and for an eligibility classification. The purpose of this article is to provide an overview of academic assessment practices in the schools by highlighting best practices in ASD evaluation, outlining ASD academic profiles and how to identify academic skill deficits, and reviewing the available literature that comes from different formal- and function-based assessment practices that are commonly used in schools today. The authors also discuss how formal- and function-based assessments both serve a purpose and are recommended to be used in conjunction with one another to best demonstrate a student's academic profile. Practitioners are ultimately encouraged to use a multi-informant, multi-modal approach when it comes to psychoeducational evaluations for individuals with ASD as it is evident that an individualized approach is essential due to the discrepancy of academic profiles related to this disability category as well as understanding that no measure is a perfect representation of any one skill.     

R&D边际生产力驱动区域经济收敛研究

区域经济收敛性一直是发展经济学研究的热点问题之一。在建立RD边际生产力的测量模型基础上,探讨了中国30省市1999-2010年间RD边际生产力对区域经济收敛的驱动效应。研究结果表明RD边际生产力对区域经济收敛存在显著的驱动效应,并且RD边际生产力驱动区域经济收敛存在1期滞后。研究还发现东部RD投入过量,西部RD投入不足,中部RD投入比较合理。

Concatenated Trellis Coding and CPM for DS/SSMA Communications in Rayleigh Fading Channel

本文在衰落信道下将级联网格编码调制（ＴＣＭ）和连续相位调制（ＣＰＭ）应用于直接序列扩频多址（ＤＳ／ＳＳＭＡ）系统中．作者分别采用了理论分析和数值模拟两种方法研究了级联ＴＣＭ／ＣＰＭＤＳ／ＳＳＭＡ系统的性能，结果表明在相同的条件下采用级联ＴＣＭ／ＣＰＭ编码调制方式的ＤＳ／ＳＳＭＡ系统的错误概率远小于采用单一ＴＣＭ或ＣＰＭ的ＤＳ／ＳＳＭＡ系统的错误概率．     

Design and development of VR learning environments for children with ASD

Basic social interaction and executing certain tasks can be difficult for children with autism spectrum disorder (ASD). The symptoms of such behaviour include inappropriate gestures, body language and facial expressions, lack of interest in certain tasks, cognitive disability in coordination of limbs, and a difficulty in comprehending tasks’ requirements. This paper will discuss our efforts to develop virtual learning environments for children with ASD to improve their gestures and their interests in comprehending tasks’ requirements. Virtual environments are ideal for imparting skills necessary for independence before encouraging children with ASD to try these out in the real world and gain real-life experience. A high-end solution and a simplified solution will be presented together with a discussion on their comparison study.

经济增长理论的拨乱反正——针对新古典经济增长理论

新古典经济增长理论从头至尾都是错误的,它只是一套由数学工具杜撰而成的理论。在技术不变条件下,资本和劳动的比例只能是固定的,边际产量递减规律只是幻觉。只有技术进步才能使资本劳动比例上升,但资本边际产量递减的结论在这样的条件下不能成立;技术进步使得人均资本量以及人均产量增长,因此,技术进步率、人均资本量增长率以及人均产量增长率三者相等;在长期中,产业结构的变化以及第三产业比重的不断提高会导致技术进步率、人均资本量和人均产量增长率呈现下降趋势。     

紫外光谱法研究久效磷与碱基的相互作用

为利用组合化学原理构建核酸适体库,确定久效磷适体筛选缓冲体系的最适 pH 值及离子强度,采用紫外吸收光谱法研究了不同 pH 值及不同 Na ﹢、K ﹢和 Mg2﹢浓度的缓冲溶液中久效磷与四种碱基的相互作用。结果表明,pH 值及 Na ﹢、K ﹢和 Mg2﹢浓度对久效磷与四种碱基的作用有明显的影响,pH7.6、Na ﹢浓度200 mmol/ L、K ﹢浓度40 mmol/ L、Mg2﹢浓度15 mmol/ L 的50 mmol/ L Tris 缓冲溶液中久效磷与四种碱基的作用相对较强,可以作为久效磷适体筛选的参考缓冲体系。在此缓冲体系下,久效磷与四种碱基作用的强弱依次为胞嘧啶、胸腺嘧啶、腺嘌呤、鸟嘌呤。因此,构建核酸适体库时可以适当增加胞嘧啶、胸腺嘧啶的比例。
