The goals of this study were to determine the relations between having a balanced time perspective (BTP) with various measures of subjective well-being (SWB) and to test how various operationalizations of a BTP might impact the relation between having a BTP and SWB. We operationalized a balanced time perspective using: (a) Drake et al.’s Time Soc 17(1):47–61, (2008) cut-off-point method, (b) Boniwell et al.’s J Posit Psychol 5(1):24–40, (2010) suggestion of using a hierarchical cluster analysis, and (c) a deviation from a balanced time perspective (DBTP; Stolarski et al. Time Soc, 2011). The results demonstrated that having a BTP is related to increased satisfaction with life, happiness, positive affect, psychological need satisfaction, self-determination, vitality, and gratitude as well as decreased negative affect. Also, the DBTP was the best predictor of SWB. We discuss why individuals with a BTP are likely to be happier in life. 相似文献

在传统工作记忆刷新和选择性注意任务上,在匹配反应阶段均涉及符号检索的心理加工过程,注意缺陷多动障碍和阅读障碍儿童的工作记忆和注意缺陷已经被证实,本研究关注于两种障碍儿童是否存在符号检索能力的缺陷。研究比较了18名ADHD儿童、11名阅读障碍儿童和17名控制组儿童在RSVP任务中序列搜索和平行搜索的成绩差异,搜索条件通过实验材料(字母和数字)和呈现方式加以操控。结果表明,在平行搜索和序列搜索条件下,障碍儿童的成绩均低于正常控制组,两组障碍儿童成绩差异不显著;在搜索效应上,三组儿童的差异不显著,这说明注意缺陷 相似文献

在维瑟(Albert Visser)的基本命题逻辑(BPL)基础上增加公理(p→q)∨((p→q)→p)得到的逻辑LB相对于弱连通传递框架类是完全的。增加达米特(M.Dummett)公理(p→q)∨(q→p)得到的逻辑LD是不完全的。本文还证明LB具有有穷模型性质,但是不具有两常元性质和析取性质。 相似文献

This study examined the relationship between ninth-grade students’ use of connectives (temporal, causal, adversative, and additive) in functional writing and performance on standards-based/criterion-referenced measures of reading and writing. Specifically, structural equation modeling (SEM) techniques were used to examine the relationship between students’ use of connectives in their functional writing and their reading and writing proficiency. Results indicated that the number of connectives used in functional writing was significantly correlated to writing test scores and reading comprehension test scores, no matter whether the effect of the common predictor was removed or not. The results provide support for future research in the study of connective words in relation to functional writing skills and reading comprehension. 相似文献

以摩梭人和汉族的高中生为对象,采用自由分类法,考察在满月酒、结婚和吊唁情境的亲属词概念结构,揭示微观文化情境对亲属关系认知的影响以及与宏观文化情境的交互作用。结果发现:(1)在不同情境下,摩梭人和汉族人对亲属词的分类既有相同之处,又存在差异。两个民族都看重"亲属的亲密程度"和"辈分",但摩梭人还区分"照顾者/被照顾者",汉族人还考虑"性别"和"亲属关系的性质";(2)摩梭人对亲属词的分类体现了母系文化的特征,重视舅舅和外甥在亲属关系中的地位和作用;汉族人对亲属词的分类体现了汉文化的特征,重视媳妇和孙辈在亲属关系中的地位和作用。(3)亲属概念具有核心特征与情境依赖特征。文化和情境通过概念特征的激活和分类标准的采择影响对亲属词的分类。 相似文献

In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) versus indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelasticity. Here we report experiments which show that hysteresis can exist in the absence of these effects, and that its magnitude depends on surface roughness. We develop a theoretical model in which the hysteresis appears as the result of a series of surface instabilities, in which the contact area grows or recedes by a finite amount. The model can be used to estimate material properties from contact experiments even when the measured P–h curves are not unique. 相似文献

In previous works, in which the topological model has been applied to martensitic phase transformations, the value of twist angle ω was determined based on the habit plane-(HP) matching method, where the physical realization of the so-predicted interfacial defect networks may require reorientations of defect line directions by short-range diffusion, though no long-range diffusion was needed. In the present work, a novel criterion for determining the optimum value of twist is proposed so that the predicted interface defects are not only able to fulfil the function of fully accommodating the coherency strains arising on the terrace plane, but also capable of reaching the required position at the HP without long- or short-range diffusions. A numerical analysis for an Fe–20Ni–5Mn alloy is demonstrated based on the newly proposed criterion, and the predictions so obtained are in good agreement with the results provided by the phenomenological theory and experimental measurements. 相似文献

Stainless steel (316L) and 8 mol pct Y2O3-stabilized zirconia (8Y-ZrO2) were bonded using a Ti–Ni–Ti multilayer at 1173 K (900 °C) for 1 h. Cross-sectional transmission electron microscopy specimens were prepared by an innovative focused ion beam plus lift-out technique. In addition to acicular α-Ti, the dissolution of Fe, Cr, and Ni diffusing outwards from 316L into β-Ti led to the precipitation of the omega (ω) phase with different variants in the residual Ti foil between 316L and Ni. The ω-phase was not found in the residual Ti foil between Ni and 8Y-ZrO2, while Ti2Ni precipitates were precipitated in some α-Ti grains owing to the exclusion of Ni from the β-Ti. 相似文献
