The microhardness and microstructural characteristics and subsequent heat treatment of conventionally solidified Al64Cu20Fe12Si4 quasicrystal were investigated by X-ray diffractometry (XRD), scanning electron microscopy (SEM) together with energy dispersive spectroscopy (EDS), differential thermal analysis (DTA), and Vickers microhardness tester. XRD analysis indicated that the conventionally solidified samples showed a quasicrystalline icosahedral phase (i-phase) together with cubic β-AlFe, tetragonal θ-Al2Cu, and monoclinic λ-A13Fe4 crystal phases. However, the i-phase together with cubic β-AlFe and monoclinic λ-A13Fe4 phases observed heat threaded samples. As-cast and subsequently heat-treated quasicrystal samples were measured using a microhardness test device. Vickers microindentation tests were carried out on the heat-treated quasicrystal samples with the load ranging from 1 to 500?mN at room temperature. The melting point of the i-phase was determined as 900°C by DTA examinations. 相似文献

The present study aimed to explore the relation between students’ oral reading efficacy, reading comprehension, and academic performance on a nationwide high school placement exam (TEOG). The students were selected from a public middle school. The students’ oral reading efficacy, comprehension, and TEOG achievement scores were obtained to figure out the relations between them. The students’ TEOG results were obtained from the school administration. The findings revealed that there were statistically significant relations between oral reading efficacy, reading comprehension and TEOG achievements. Particularly, students’ reading comprehension and accuracy skills together explained 57% of variance in overall TEOG achievements. 相似文献

Making decisions using judgements of multiple non-deterministic indicators is an important task, both in everyday and professional life. Learning of such decision making has often been studied as the mapping of stimuli (cues) to an environmental variable (criterion); however, little attention has been paid to the effects of situation-by-person interactions on this learning. Accordingly, we manipulated cue and feedback presentation mode (graphic or numeric) and task difficulty, and measured individual differences in working memory capacity (WMC). We predicted that graphic presentation, fewer cues, and elevated WMC would facilitate learning, and that person and task characteristics would interact such that presentation mode compatible with the decision maker's cognitive capability (enhanced visual or verbal WMC) would assist learning, particularly for more difficult tasks. We found our predicted main effects, but no significant interactions, except that those with greater WMC benefited to a larger extent with graphic than with numeric presentation, regardless of which type of working memory was enhanced or number of cues. Our findings suggest that the conclusions of past research based predominantly on tasks using numeric presentation need to be reevaluated and cast light on how working memory helps us learn multiple cue–criterion relationships, with implications for dual-process theories of cognition. 相似文献

Employees’ innovative work behaviour can help firms’ competitiveness. Existing research focuses on several factors, including HR policies, psychological empowerment as well as manager and co-worker support, to explain innovative work behaviour. However, much of this literature analyses just one of these, neglecting how they interact and limiting our understanding of the causes of innovative work behaviour. Synthesizing this work, we develop a novel and holistic framework that examines 1) how high-involvement HR systems are linked via the mediating role of psychological empowerment to innovative work behaviour and 2) how both manager and co-worker support moderate this relationship. Analysing software companies in Pakistan, we use hierarchical linear modelling to assess this framework. We draw on a unique dataset that captures HR policies at the organizational level as well as management and co-worker support, and supervisors’ assessments of individuals’ innovative work behaviour at the individual level. We analyse specific groups of HR practices. Psychological empowerment mediates the relationship between high-involvement HR systems and employees’ innovative work behaviour. Manager and co-worker support moderate the relationship between psychological empowerment and innovative work behaviour. Motivation-enhancing HR practices have a direct effect on innovative work behaviour, whereas ability- and opportunity-enhancing ones are mediated by psychological empowerment. 相似文献

Science has been dazzlingly successful in explaining nature. Scientific advances also have led to certain undesirable, though unintended, side effects, one of which is alienation from the spiritual. Revelation comes from the Divine. But what is the status of authenticity of a particular piece claimed to be revelation? What is its historical validity and current state of preservation? This essay proposes to develop a list of rational criteria, in consultation with all stakeholders, for addressing the subject. The aim is to bring objectivity into this discourse by placing it more on the turf of reason rather than basing it on considerations of faith and prior allegiance. 相似文献

Two experiments were performed to replicate the results of Ilan and Miller that response selection but no response-hand specific
preparation is present during memory scanning. Letter-case determined which hand would respond, while memory set membership
status determined whether the response was to be executed (go) or withheld (nogo). In Exp. 1, the LRP was observed as an index
of response-hand specific preparation. In Exp. 2, the consistency effect derived from the response priming paradigm was observed
as an index of more central response selection. The results replicate those of Ilan and Miller and suggest that central response
selection is present during short-term memory scanning, but hand-specific response preparation is absent. Apparently, preliminary
information is transmitted to the response selection stage during memory scanning, a finding that is inconsistent with serial
stage models, but memory scanning interferes with hand-specific response preparation.

Al-Māturīdī and Duns Scotus share an ethical paradigm that represents the middle ground between divine command and natural law theories in ethics. While al-Māturīdī’s theory can generally be located between Ash?arite divine command and Mu?tazilite natural law theories in Islamic ethics, Scotus’s theory can be placed between William of Ockham’s divine command and Thomas Aquinas’s natural law theories in Christian ethics. Although the starting point of their ethical perspectives is fundamentally based on criticism of natural law theory, neither theologian can be labelled as a typical divine command theorist. This moderate theory may therefore be described as the theory of soft divine command. The main purpose of this article is to draw attention to some similarities between al-Māturīdī’s and Duns Scotus’s ethical perspectives: First, both theologians highlight the composite picture of human nature in terms of morality. In other words, they posit that humans have two opposite tendencies: ‘affection for justice’ and ‘affection for advantage’. Second, although both theologians grant reason an ontological authority in determining what is good and bad, this authority is not limitless. Finally, both theologians argue that, unless one takes account of God’s freedom and wisdom, the moral order in the world cannot be fully comprehended. 相似文献

AbstractThis is a mixed-design study that examines the effects of a psychoeducation program on family functioning and the parent-adolescent relationship. The quantitative dimension of the study was quasi-experimental and included the pretest, post-test and follow-up model with control and experiment groups. The data were collected from both parents and adolescents. In the study, there were 32 adolescents in the experiment group (18 male, 14 female), while the control group consisted of 31 adolescents (15 male, 16 female). The results of the study show that the education program decreases the problem behaviors of adolescents while increasing family functions and promoting the adolescent-parent relationship 相似文献

Basketball players’ responses to an opposing players’ pass direction are typically delayed when the opposing player gazes in another than the pass direction. Here, we studied the role of basketball expertise on this, the so-called head-fake effect, in three groups of participants (basketball experts, soccer players, and non-athletes). The specific focus was on the dependency of the head-fake effect on previous fake experience as an index of control over the processing of task-irrelevant gaze information. Whereas (overall) the head-fake effect was of similar size in all expertise groups, preceding fake experience removed the head-fake effect in basketball players, but not in non-experts. Accordingly, basketball expertise allows for higher levels of control over the processing of task-irrelevant gaze information. 相似文献
