Although multidimensional scaling (MDS) profile analysis is widely used to study individual differences, there is no objective
way to evaluate the statistical significance of the estimated scale values. In the present study, a resampling technique (bootstrapping)
was used to construct confidence limits for scale values estimated from MDS profile analysis. These bootstrap confidence limits
were used, in turn, to evaluate the significance of marker variables of the profiles. The results from analyses of both simulation
data and real data suggest that the bootstrap method may be valid and may be used to evaluate hypotheses about the statistical
significance of marker variables of MDS profiles. 相似文献

In the wake of the Arab Revolutions of 2011, countries in the Middle East are grappling with how Islamists might be included within a regime of democratic political pluralism and how their aspirations for an “Islamic state” could affect the citizenship status of non-Muslims. While Islamic jurisprudence on this issue has traditionally classified non-Muslims in Islamic society as protected peoples or dhimma, endowed with what the authors term “minority citizenship”, this article will examine how the transnational intellectual Wasa?iyya or Centrist movement, of which Sheikh Yusuf al-Qaradawi is the figurehead, have sought to develop a new fiqh of citizenship in which Muslims and non-Muslims have equal civil and political rights. This article will focus on Yusuf al-Qaradawi on the basis that his very recent shift in 2010 on the issue is yet to be studied in depth, as well as in view of the fact that the dilemma faced by reformist Islamic scholars—how to integrate modern concepts into a legal tradition while simultaneously arguing for that tradition’s continuing relevance and authority—is for him rendered particularly acute, given that this tradition is itself the very source of his own authority and relevance. It will therefore be argued that the legacy of the Islamic legal tradition structures his discourse in a very specific way, thereby having the potential to render it more persuasive to his audience, and worthy of a more detailed examination. 相似文献

Previous studies have shown that negative emotional distracters impair conscious inhibitory control. Recent research has shown that inhibitory control can be triggered unconsciously; therefore, in Experiment 1, we aimed to investigate whether negative emotional distracters affect unconscious inhibitory control. Furthermore, in Experiment 2, we examined whether fearful and disgusting distracters have differential effects on unconscious inhibitory control. Participants were instructed to perform a masked Go/No-Go task superimposed on a negative or neutral image cue (Experiment 1) or on a fearful, disgusting or neutral image cue (Experiment 2). Results showed that negative emotional distracters impaired unconscious inhibitory control; furthermore, disgusting distracters impeded unconscious inhibitory control when compared to fearful ones. This study is the first to provide evidence that fear and disgust may affect unconscious inhibitory control differently. These results expand the understanding of the relationship between emotions and inhibitory control. 相似文献

A sophisticated and flexible understanding of the equals sign (=) is important for arithmetic competence and for learning further mathematics, particularly algebra. Research has identified two common conceptions held by children: the equals sign as an operator and the equals sign as signaling the same value on both sides of the equation. We argue here that, in addition to these two conceptions, the notion of substitution is also an important part of a sophisticated understanding of mathematical equivalence. We provide evidence from a cross-cultural study in which English and Chinese children were asked to rate the "cleverness" of operational, sameness, and substitutive definitions of the equals sign. A principal components analysis revealed that the substitutive items were distinct from the sameness items. Furthermore, Chinese children rated the substitutive items as 'sort of clever' or 'very clever', whereas English children rated them as not so clever, suggesting that the notion of substitution develops differently across the two countries. Implications for developmental models of children's understanding of equivalence are discussed. 相似文献

As psychological instruments are converted for administration on computers, differences in luminance and contrast of these displays may affect performance. Specifically, high-luminance assessments may mask age-group differences that are apparent under lower luminance conditions. We examined the effects of luminance and contrast on object detection using computerized and naturalistic assessments. Younger and older adults displayed more differences in performance across differing contrast levels in conditions that were matched for luminance, despite the conditions appearing perceptually different. These findings indicate that computerized assessments should be created with luminance levels that are similar to those of the tasks they purport to simulate in order to enhance their validity. 相似文献

Genomic carrier screening can identify more disease-associated variants than existing carrier screening methodologies, but its utility from patients’ perspective is not yet established. A randomized controlled trial for preconception genomic carrier screening provided an opportunity to understand patients’ decisions about whether to accept or decline testing. We administered a survey to potential genomic carrier screening recipients who declined participation (N = 240) to evaluate their reasons for doing so. Two thirds of women declined participation. We identified major themes describing reasons these individuals declined to participate; the most common were time limitation, lack of interest, not wanting to know the information, and potential cause of worry or anxiety. Most women eligible for genomic carrier screening indicated that their reasons for opting out were due to logistical issues rather than opposing the rationale for testing. As expanded carrier screening and genomic sequencing become a more routine part of clinical care, it is anticipated there will be variable uptake from individuals for this testing. Thus, the advancement of clinical carrier screening from single genes, to expanded screening panels, to an exome- or genome-wide platform, will require approaches that respect individual choice to receive genetic testing for reproductive risk assessment. 相似文献
