The Assessment of Marital Adjustment with Chinese Populations: A Study of the Psychometric Properties of the Dyadic Adjustment Scale

This article presents findings from a study of the psychometric properties of the Dyadic Adjustment Scale (DAS) with 63 Chinese-Americans. The analysis revealed high internal consistency for DAS scores. Coefficient alpha for the total DAS score was r = .93. Convergent validity was established with the Locke-Wallis Marital Adjustment Scale (LWMAT) (r = .87) and divergent validity by evidence of an inverse relationship with the Marital Disaffection Scale (MDS) (r = –.79). Correlations with each measure were found to be (p = 0.01). The result of factor analysis fail to support the presence of four separate subscales. Results show that the global DAS score is of potential utility with Asian samples.     

A new quantile estimator with weights based on a subsampling approach

Quantiles are widely used in both theoretical and applied statistics, and it is important to be able to deploy appropriate quantile estimators. To improve performance in the lower and upper quantiles, especially with small sample sizes, a new quantile estimator is introduced which is a weighted average of all order statistics. The new estimator, denoted NO, has desirable asymptotic properties. Moreover, it offers practical advantages over four estimators in terms of efficiency in most experimental settings. The Harrell–Davis quantile estimator, the default quantile estimator of the R programming language, the Sfakianakis–Verginis SV2 quantile estimator and a kernel quantile estimator. The NO quantile estimator is also utilized in comparing two independent groups with a percentile bootstrap method and, as expected, it is more successful than other estimators in controlling Type I error rates.     

主题与类属关系的距离对分类和属性推理过程的影响：来自ERP的证据

不同关系类型对归纳推理具有重要的影响,然而主题关系（如,熊猫vs.竹子）与类属关系（如,熊猫vs.羚羊）在归纳推理中的神经机制仍然不清楚。本研究采用事件相关电位（ERP）技术,通过分开呈现属性归纳推理任务中的结论类别和结论属性,探讨两种关系类型及其距离在分类过程和属性推理过程中的ERP特征。结果发现：（1）结论类别呈现阶段,N400（370～500 ms）与LNC（the late negative component）（570～700 ms）时间窗口上,无论是主题关系还是类属关系,远距离比近距离均诱发了更大的负波;前者表明N400与语义整合密切相关,后者说明LNC与语义类别信息违背和假设形成有关。（2）结论属性呈现阶段,主题关系比类属关系诱发了更大的N1;同时,近距离比远距离诱发了更大的N1,反映了类别属性特征的知觉和自动化加工。结果表明：语义类别属性归纳存在距离效应,并且语义关系在属性推理过程中具有不同的加工方式。     

Children's understanding of human and super-natural mind

Barrett, Richert, and Driesenga [Barrett, J. L., Richert, R. A., & Driesenga, A. (2001). God's beliefs versus mother's: The development of nonhuman agents concepts. Child Development, 72(1), 50–65] have suggested that children are able to conceptualize the representational properties held by certain super-natural entities, such as God, before they achieve representational understanding of the human mind. The two experimental conditions of the present study aimed at cross-checking the above suggestion. One hundred and twenty children aged from 3 to 7 years were involved in both conditions. In the first, a modified perspective-taking and appearance-reality task, similar to that adopted in Barrett et al.'s study, was used. The task in the second addressed another aspect of representational understanding of the human mind, that is, the early emerging of the rule that knowledge is constrained by perception. The results of the study showed that younger children systematically treat God as a human protagonist regarding the representational properties they possess. Moreover, it was found that children are able to reason, accurately, about God's representational properties, only upon reaching their 5th year of age, when their representational understanding of the human mind becomes stable and robust.     

Career adaptability in Lithuania: A test of psychometric properties and a theoretical model

The Career Adapt-Abilities Scale-Lithuanian Form consists of four six-item subscales measuring concern, control, curiosity, and confidence. These are thought to be the main dimensions of career adaptability reflecting individual psychosocial resources to cope with occupational transitions, developmental tasks, and work traumas. Two studies were administered in a sample (N  =  767) of Lithuanian high school students. The results showed factor structure to be identical to that of the CAAS-International Form. Moreover, good to excellent scale internal consistency coefficients were obtained. With a slight exception, MIMIC model analysis revealed no major effects of demographic variables upon the CAAS factor or factor indicator scores. Concurrent validity analysis showed career adaptability, as measured by the CAAS-Lithuanian Form, to be significantly related to career aspirations, to the frequency of career exploration behaviors and to career decidedness. Finally, as hypothesized by the career construction model of adaptation, career exploration behaviors mediated the link between career adaptability and decidedness.     

Explaining prompts children to privilege inductively rich properties

Four experiments with preschool-aged children test the hypothesis that engaging in explanation promotes inductive reasoning on the basis of shared causal properties as opposed to salient (but superficial) perceptual properties. In Experiments 1a and 1b, 3- to 5-year-old children prompted to explain during a causal learning task were more likely to override a tendency to generalize according to perceptual similarity and instead extend an internal feature to an object that shared a causal property. Experiment 2 replicated this effect of explanation in a case of label extension (i.e., categorization). Experiment 3 demonstrated that explanation improves memory for clusters of causally relevant (non-perceptual) features, but impairs memory for superficial (perceptual) features, providing evidence that effects of explanation are selective in scope and apply to memory as well as inference. In sum, our data support the proposal that engaging in explanation influences children’s reasoning by privileging inductively rich, causal properties.     

Optical characterization of spin-coated cobalt porphyrazine thin films: effect of annealing temperature

Cobalt porphyrazine thin films were prepared by the spin-coating technique. The coated substrates were annealed at different temperatures (373, 423 and 523 K). The optical properties of the films were investigated by measuring the transmittance and reflectance spectra. The refractive index, extinction coefficient, optical band gap, dielectric constant values and thickness of the films were determined. Results showed that the refractive index, the extinction coefficient and the dielectric constants increased on annealing the films at 373 K in comparison with films annealed at other temperatures. On the other hand, the values of the band gap energy and thickness of the annealed film at 373 K were found to be the lowest in comparison with films annealed at different temperatures.     

Plastic stability of bimetals composed of Ti-based metallic glass composite and pure titanium

The plastic stability of bimetals composed of a Ti-based metallic glass composite (MGC) and a pure titanium (PT) under tension has been investigated. The results reveal that the plastic stability of the MGC/PT bimetal is strongly dependent on the thickness fraction of the MGC: when the thickness fraction of the MGC decreases to a critical value, a homogeneous plastic deformation occurs in the MGC/PT bimetals, i.e. the strain localization and necking of the MGC is effectively suppressed. This unique phenomenon is explained using the normalized strain-hardening rate, and the quantitative relationship between the normalized strain-hardening rate of the MGC/PT bimetals and the thickness fraction of the MGC is thereby established.     

Reversible phase transition in vanadium oxide films sputtered on metal substrates

Vanadium oxide films, deposited on aluminium (Al), titanium (Ti) and tantalum (Ta) metal substrates by pulsed RF magnetron sputtering at a working pressure of 1.5 x10^?2 mbar at room temperature are found to display mixed crystalline vanadium oxide phases viz., VO₂, V₂O₃, V₂O₅. The films have been characterized by field-emission scanning electron microscopy, X-ray diffraction, differential scanning calorimetry (DSC) and X-ray photoelectron spectroscopy, and their thermo-optical and electrical properties have been investigated. Studies of the deposited films by DSC have revealed a reversible-phase transition found in the temperature range of 45–49 °C.
