"这篇论文是心理学在学校的期刊文章,发表于1986年7月,作者是Jerome M. Satter和Theron M. Covin,来自圣地亚哥州立大学的咨询与人类发展中心。研究对比了修订版的Slosson智力测试(SIT)和Wechsler智力量表修订版(WISC-R),在这两个测试中分别对有学习障碍的儿童和天才儿童进行了评估。" 在这项研究中,Slosson智力测试(SIT)的修订版和WISC-R被用于两组不同的儿童样本进行比较。第一组样本包括34名黑人和27名白人农村地区的阿拉巴马儿童,这些儿童可能需要特殊教育。第二组样本则有4名黑人和81名白人郊区的阿拉巴马儿童,他们正在考虑进入天才班。在两个样本中,SIT智商与WISC-R全量表智商之间的相关性均具有统计学意义(相关系数分别为0.70和0.48)。 然而,在特殊教育样本中,SIT智商显著高于WISC-R全量表智商约7分。这表明,尽管修订后的SIT标准在一定程度上得到了WISC-R作为标准的同时效度支持,但两个测试的智商得分可能并不完全可互换。这意味着它们可能对不同类型的儿童群体表现出不同的敏感性,特别是对于有特殊学习需求和天赋儿童的评估。 Slosson智力测试(SIT)的修订版更新了其标准化数据,以更好地适应不同群体。而WISC-R作为另一种广泛接受的智力评估工具,尤其在识别和理解学习障碍方面有着重要的应用。通过这两个测试的对比,研究者试图揭示哪种工具更能准确地反映特定儿童群体的智力水平,并提供有关如何在特殊教育和天才教育领域中选择适当的评估工具的见解。 这项研究为教育心理学家、心理咨询师以及特殊教育工作者提供了关于如何选择和解读不同智力测试结果的重要信息,强调了在评估儿童智力时,不仅要考虑测试的效度,还要考虑其可能存在的文化、社会和个体差异的影响。同时,这项工作也为未来在智力评估领域内的研究提供了基础,以进一步改进和优化测试方法,确保公平且准确地评估所有儿童的能力。

4 Experiments This section examines the effectiveness of the proposed IFCS-MOEA framework. First, Section 4.1 presents the experimental settings. Second, Section 4.2 examines the effect of IFCS on MOEA/D-DE. Then, Section 4.3 compares the performance of IFCS-MOEA/D-DE with five state-of-the-art MOEAs on 19 test problems. Finally, Section 4.4 compares the performance of IFCS-MOEA/D-DE with five state-of-the-art MOEAs on four real-world application problems. 4.1 Experimental Settings MOEA/D-DE [23] is integrated with the proposed framework for experiments, and the resulting algorithm is named IFCS-MOEA/D-DE. Five surrogate-based MOEAs, i.e., FCS-MOEA/D-DE [39], CPS-MOEA [41], CSEA [29], MOEA/DEGO [43] and EDN-ARM-OEA [12] are used for comparison. UF1–10, LZ1–9 test problems [44, 23] with complicated PSs are used for experiments. Among them, UF1–7, LZ1–5, and LZ7–9 have 2 objectives, UF8–10, and LZ6 have 3 objectives. UF1–10, LZ1–5, and LZ9 are with 30 decision variables, and LZ6–8 are with 10 decision variables. The population size N is set to 45 for all compared algorithms. The maximum number of FEs is set as 500 since the problems are viewed as expensive MOPs [39]. For each test problem, each algorithm is executed 21 times independently. For IFCS-MOEA/D-DE, wmax is set to 30 and η is set to 5. For the other algorithms, we use the settings suggested in their papers. The IGD [6] metric is used to evaluate the performance of each algorithm. All algorithms are examined on PlatEMO [34] platform.

Traditional network security situation prediction methods depend on the accuracy of historical situation value. Moreover, there are differences in correlation and importance among various network security factors. In order to solve these problems, a combined prediction model based on the temporal convolution attention network (TCAN) and bi-directional gate recurrent unit (BiGRU) network optimized by singular spectrum analysis (SSA) and improved quantum particle swarm optimization algorithm (IQPSO) was proposed. This model was first decomposed and reconstructed into a series of subsequences through the SSA of network security situation data. Next, a prediction model of TCAN-BiGRU was established for each subsequence, respectively. The TCN with relatively simple structure was used in the TCAN to extract features from the data. Besides, the improved channel attention mechanism (CAM) was used to extract important feature information from TCN. Afterwards, the before-after status of the learning situation value of the BiGRU neural network was used to extract more feature information from sequences for prediction. Meanwhile, an improved IQPSO was proposed to optimize the hyper-parameter of the BiGRU neural network. Finally, the prediction results of subsequence were superimposed to obtain the final predicted value. In the experiment, on the one hand, the IQPSO was compared with other optimization algorithms; and the results showed that the IQPSO has better optimization performance; on the other hand, the comparison with traditional prediction methods was performed through the simulation experiment and the established prediction model; and the results showed that the combined prediction model established has higher prediction accuracy.
