共产主义信念对道德认知的影响及认知机制

基于五个实验研究联合使用单类内隐联想范式与概念启动范式,探讨了共产主义信念与道德认知的关系及其认知机制。结果显示:(1)共产主义信念与道德在概念层面具有相容性;(2)在阈上、阈下水平启动共产主义信念均能够显著促进道德概念判断;(3)共产主义信念促进道德判断的启动效应呈现累积趋势,符合证据累积模型,而在词汇决定任务下未出现概念的扩散激活效应,不符合扩散激活模型。系列研究表明,新时代中国特色社会主义背景下,共产主义信念与道德认知产生了显著地关联,共产主义信念启动能够促进道德判断,且共产主义信念促进道德判断的启动效应并不是发生在语义层面,而是知觉层面。     

不同心理一致感初中生对压力的态度激活研究

该研究采用不同加工任务的间接测量方法,探讨不同心理一致感水平初中生对压力的外显认知倾向和内隐态度激活程度。结果表明:1)初中生较为稳定的积极认识和反应倾向在他们关于压力的外显认知加工中起了更为显著的作用;2)不同加工方式的虚惊率差异表明存在着初中生对压力情境的内隐态度,且这种无意识认知较为消极。     

A new orthorhombic approximant of the icosahedral Al–Cu–Fe quasicrystal

We report on the formation of a new crystalline approximant phase of the icosahedral (i-)Al–Cu–Fe quasicrystal. This phase is formed during sintering of Al-based composites reinforced with i-AlCuFeB quasicrystalline particles. The structure of this phase has been characterized by transmission electron microscopy (TEM) and high-resolution electron microscopy (HREM). TEM revealed that it is a B-centred orthorhombic phase with lattice parameters a = 1.166 nm, b = 1.195 nm and c = 3.44 nm. Its chemical composition, as determined by electron energy loss spectroscopy (EELS), is close to Al_76.9Cu_2.7Fe_20.4, with an average number of valence electrons per atom e/a of 1.92, similar to the value in all other approximants of the i-phase discovered thus far. Initial results on local atomic arrangements along one of its pseudo-5-fold axes are also presented.     

Effect of lithium-ion irradiation on the crystallization kinetics of glassy Se98In2

Differential scanning calorimetry (DSC) has been used to study the crystallization kinetics of glassy Se₉₈In₂ both before and after irradiation of the alloy with high-energy (50 MeV) lithium ions. After the ion-irradiation, significant changes in the kinetic parameters of crystallization of the glass were observed. The results are explained in terms of a model involving irradiation-induced defects.     

Differential effects of the different Short Self-Applied Relaxation Therapy (SART) components on anxiety,activation and stress / Efectos diferenciales de los distintos componentes de la Relajación Breve Sugestiva Auto aplicada (RBSA) sobre la ansiedad,la activación y el estrés

Abstract

Relaxation techniques have evidence-based support in the research community. However, not all relaxation techniques have the same effectiveness or generate the same states of relaxation. For this reason, indications should be established for each of them. Studies into Self-Applied Relaxation Therapy (SART) show that they can decrease anxiety, stress, blood pressure and craving. This study explores to what extent each SART component is responsible for the results found, which is the most appropriate depending on the target variable to be controlled and whether any of the components are dispensable. Ninety-three university volunteer students participated in the study, aged between 18 and 45; 81.70% were female. Results showed that each of the components had similar efficacy and paradoxical effects on certain participants (8% to 26%). From a clinical perspective, this study concludes that SART can be adapted to the user, and a specific combination of components should be designed for each patient.     

The prediction of turnover intention by means of employee engagement and demographic variables in a telecommunications organisation

This study sought to determine the prediction of turnover intention by employee engagement and demographic variables in a large South African information and communication technology (ICT) organisation. Cross-sectional survey data was collected from the organisation. Using a sample of 2276 participants the Utrecht Work Engagement Scale (UWES) was employed to measure employee engagement, while the Intention to Stay Questionnaire (ISQ) measured turnover intentions. Employee engagement was significantly negatively related with turnover intentions. A factor analysis conducted on the UWES indicated that activation accounted for 10% of the variance in turnover intentions. Age and tenure had statistically significant negative relationships with turnover intentions, whilst qualification and race had significant positive relationships with turnover intentions. The results also confirmed the predictive model of employee engagement as well as the impact of the demographic variables of race, age, tenure on turnover intentions. The study has practical implications in relation to its ability to contribute to human resources activities in the form of differentiated remuneration and retention strategies based on differences in age and tenure.     

Muscle Damaging Exercise Affects Isometric Force Fluctuation as well as Intraindividual Variability of Cognitive Function

Healthy untrained men (N = 11) were asked to perform 10 series of 12 repetitions of knee eccentric extension (EE) at 160° per second. Quadriceps muscle torques evoked by electrical stimulation at 20 Hz (P20) and 100 Hz (P100), maximal voluntary isometric contraction torque (MVC), maximal isokinetic concentric torque (IT) at 30° per second, voluntary activation index (VA), simple reaction time (RTs), complex reaction time (RTc), and torque variability at 30% of MVC were measured before EE, immediately after EE, and 60 min and 24 hr after EE. MVC, IT, P20, P100, and VA decreased significantly after EE and remained depressed 24 hr later. Torque variability increased significantly after EE. Average RTs and RTc did not change after EE, whereas intraindividual variability in RTs and RTc increased significantly after EE.     

Response Facilitation and Inhibition in Manual,Vocal, and Oculomotor Performance: Evidence for a Modality-Unspecific Mechanism

In 2 experiments (N = 10, Experiment 1; N = 16, Experiment 2), the authors investigated whether evidence for response facilitation and subsequent inhibition elicited by masked prime stimuli can be observed for output modalities other than manual responding. Masked primes were followed by target stimuli that required a 2-choice manual, saccadic, or vocal response. Performance was measured for compatible trials in which primes and targets were identical and for incompatible trials in which they were mapped to opposite responses. When primes were presented centrally, performance benefits were obtained for incompatible trials; whereas for peripherally presented primes, performance benefits were found in compatible trials. That pattern of results was obtained for manual responses and for saccadic eye movements (Experiment 1), demonstrating that those effects are not mediated by specialized dorsal pathways involved in visuomanual control. An analogous pattern of effects was found when manual and vocal responses were compared (Experiment 2). Because vocal responding is controlled by the inferotemporal cortex, that result shows that prime-target compatibility effects are not primarily mediated by the dorsal stream, but appear to reflect modality-unspecific visuomotor links that allow rapid activation of motor responses that may later be subject to inhibition.
