国外学者关于毛泽东《矛盾论》的复调式解读——从《辩证法的内部对话》与《保卫马克思》的分歧谈起

该文以《辩证法的内部对话》和《保卫马克思》为文本依托,尝试从西方马克思主义人本主义与科学主义两条线索的辩证互动出发,探讨毛泽东《矛盾论》这一作品在黑格尔主义与反黑格尔主义之间的复调式理论立场,从而对《矛盾论》中的哲学逻辑从辩证法与本体论的意义上加以澄明。     

从结构主义到后结构主义（上）

我们把读者的记忆倒退20多年前,当二十世纪八十年代初中国开始介绍法国结构主义时,在它的故乡,这种哲学方法已经渐渐被后结构主义或解构主义所取代.令人遗憾的是,多年来国内对结构主义的研究一直没有真正的展开,总体上仍然限于翻译和一般性介绍,对于其对西方传统哲学乃至文明的颠覆作用一直缺少准确意义上的理解,这种偏差源于结构主义奠基于与我们的象形文字并不一致的索绪尔语言学理论,使我们从汉字文化角度理解它非常困难.     

Deformation behaviour and 6H-LPSO structure formation at nanoindentation in lamellar high Nb containing TiAl alloy

Microstructure and deformation mechanisms at a nanoindentation in the lamellar colony of high Nb containing TiAl alloy have been studied using the focused ion beam and the transmission electron microscopy. Considerable deformation twins are observed around the nanoindentation, and a strain gradient is generated. A continuous change in the bending angle of the lamellar structure can be derived, and a strain-induced grain refinement process is observed as various active deformations split the γ grains into subgrains. In addition to all possible deformation mechanisms (ordinary dislocation, super-dislocation and deformation twining) activated due to the heavy plastic deformation, a 6-layer hexagonal (6H) long-period stacking ordered structure is identified for the first time near the contact zone and is thought to be closely related to the glide of partial dislocations.     

On initial item selection in cognitive diagnostic computerized adaptive testing

There has recently been much interest in computerized adaptive testing (CAT) for cognitive diagnosis. While there exist various item selection criteria and different asymptotically optimal designs, these are mostly constructed based on the asymptotic theory assuming the test length goes to infinity. In practice, with limited test lengths, the desired asymptotic optimality may not always apply, and there are few studies in the literature concerning the optimal design of finite items. Related questions, such as how many items we need in order to be able to identify the attribute pattern of an examinee and what types of initial items provide the optimal classification results, are still open. This paper aims to answer these questions by providing non‐asymptotic theory of the optimal selection of initial items in cognitive diagnostic CAT. In particular, for the optimal design, we provide necessary and sufficient conditions for the Q ‐matrix structure of the initial items. The theoretical development is suitable for a general family of cognitive diagnostic models. The results not only provide a guideline for the design of optimal item selection procedures, but also may be applied to guide item bank construction.     

Intermetallic compound identification and Kirkendall void formation in eutectic SnIn/Cu solder joint during solid-state aging

Microstructural investigations were performed on the interfacial reactions between eutectic SnIn solder and Cu substrate during reflowing at 433?K and solid-state aging at 373?K. Cu₂(In,Sn) was identified as the only intermetallic compound (IMC) at the interface, which consists of two sublayers with different morphology, a fine-grained sublayer at the Cu side and a coarse-grained sublayer at the solder side. During solid-state aging, voids were found between these two Cu₂(In,Sn) sublayers but not at the substrate interface, which is also attributed to the Kirkendall effect considering the different diffusion fluxes of Sn or In and Cu atoms in different sublayers.     

Re-precipitation of coherent γ-Fe particles following annealing of equal-channel angular pressed Cu–Fe alloy

The transformation of second-phase particles in a Cu–Fe alloy following equal-channel angular extrusion and annealing has been determined by transmission electron microscopy. Equal-channel angular pressing of the Cu–Fe alloy transformed coherent γ-Fe particles in the Cu matrix into incoherent α-Fe. Upon annealing, numerous coherent γ-Fe particles were observed. A dislocation–particle interaction mechanism is suggested to explain the re-precipitation of coherent γ-Fe particles following annealing.     

A study on purchasing behavior of teenagers in Taiwan: example of counterfeit goods

This study has established a relationship model encompassing such aspects as consumer values, consumer involvement, purchase behavior, and consumer satisfaction. Furthermore, taking counterfeit goods as an example, this study employs factor analysis, reliability analysis, and the structural equation model to verify the relationship between the research aspects. Another major discovery of this study was that teenagers' behavioral purchasing mentality is graphic, hyperlinked, and is geared toward useful situations and functional needs. When they consider their degree of need, they inevitably incorporate many emotional needs. However, their attitude toward counterfeit goods is rational, which is confirmed by the fact that Hypothesis 1 was not supported.

中央重新定向对听觉返回抑制的影响

采用线索一靶子范式考察听觉中央重新定向对听觉返回抑制的影响。结果表明：1）听觉中央重新定向的有无不是听觉返回抑制产生的关键因素,但它的存在能够较好地引导听觉选择性注意进行快速转移,提高听觉选择性注意的搜索效率;2）听觉中央重新定向对听觉返回抑制量的大小没有显著影响。
