Rapid advances in the genetics of amyotrophic lateral sclerosis (ALS) have dramatically changed the approach of clinicians and researchers to the motor neuron diseases. We report two siblings in whom the genetic study provided conflicting results, hence raising a number of issues which deserve to be considered by clinicians involved in genetic testing for ALS. The first patient died within 2 years of ALS onset, while her brother still manages to walk unaided, 7 years into onset. Genetic analyses, performed on the first patient as part of a research protocol, and as clinical genetic testing on the brother, provided different results. Results for Patient 1 were negative for all investigated genes, thus suggesting that her disease may be a phenocopy, while her brother carried an autosomal dominant TARDBP mutation (p.A382T). A multidisciplinary approach may help patients and clinicians face the emerging dilemmas in such a complex field. Sharing and updating of advances, not to mention uncertainties inherent to current knowledge, with patients and families may prove to be an effective way to support them and to make them aware of the present limits of our knowledge and of the blurred border between research and clinical practice.  相似文献

School violence is a global concern that calls for international research using cross context methods. Although there are several international surveys that compare school violence across countries, they do not clearly address issues of similarities and differences in relative prevalence of different types of victimization and their relations with age, sex, and cultural group. We explored these questions among Israeli-Arab (n?=?13,606), Israeli-Jewish (n?=?10,637), and Chilean students in poor schools in a large Chilean city (n?=?4557), using the same self-report questionnaire that measures verbal-social victimization, victimization by threats, physical victimization, and sexual harassment. As hypothesized, we found similarities in the patterns of relative prevalence of victimization types, as well as study group, sex, and age main effects and interactions. These effects were evident even when the lowest third SES group in Israel was compared with the Chilean students. These findings suggest group differences in prevalence of student victimization, and at the same time cultural invariance in relative prevalence of victimization types and their relations with sex and age. We discuss the need for more international comparative research in this field that takes into account cultural values and the structure and organizations of schools within the different educational systems.  相似文献

This article examines whether there are gender differences in understanding the emotions evaluated by the Test of Emotion Comprehension (TEC). The TEC provides a global index of emotion comprehension in children 3–11 years of age, which is the sum of the nine components that constitute emotion comprehension: (1) recognition of facial expressions, (2) understanding of external causes of emotions, (3) understanding of desire-based emotions, (4) understanding of belief-based emotions, (5) understanding of the influence of a reminder on present emotional states, (6) understanding of the possibility to regulate emotional states, (7) understanding of the possibility of hiding emotional states, (8) understanding of mixed emotions, and (9) understanding of moral emotions. We used the answers to the TEC given by 172 English girls and 181 boys from 3 to 8 years of age. First, the nine components into which the TEC is subdivided were analysed for differential item functioning (DIF), taking gender as the grouping variable. To evaluate DIF, the Mantel–Haenszel method and logistic regression analysis were used applying the Educational Testing Service DIF classification criteria. The results show that the TEC did not display gender DIF. Second, when absence of DIF had been corroborated, it was analysed for differences between boys and girls in the total TEC score and its components controlling for age. Our data are compatible with the hypothesis of independence between gender and level of comprehension in 8 of the 9 components of the TEC. Several hypotheses are discussed that could explain the differences found between boys and girls in the belief component. Given that the Belief component is basically a false belief task, the differences found seem to support findings in the literature indicating that girls perform better on this task  相似文献

Preference reversals between joint and separate evaluation procedures (JE and SE) were studied as a function of attribute evaluability (Hsee, 1996) and attribute importance. First, the present research replicated Hsee's (1996) JE-SE preference reversal findings with willingness-to-pay judgments. In addition, choices showed a preference pattern similar to that of willingness-to-pay judgments. Second, consistent with Hsee's (2000) speculation, the study showed that attribute importance is a key determinant of JE-SE reversal.  相似文献

The purpose of this study was to evaluate the potential of fixed‐time (FT) schedules to maintain behavior. Two children who had been diagnosed with autism were taught a functional task. Subsequently, three different FT schedules (i.e., yoked, thin, dense) were compared to determine their capacity to maintain task responding. Results suggested that FT schedules may be used to maintain previously acquired behavior.  相似文献

Dr Yusuf al-Qaradawi is one of the most prominent and respected religious scholars in the Muslim world, particularly amongst so-called moderate Islamists. In this article, we start by providing a summary of his biography, including the influence of the Muslim Brothers Society on his political and intellectual development. We will then explore his key ideas, notably the adoption of the term wasatiyya or ‘middle way’ to describe his position vis-à-vis the main questions facing both Muslims and Islam. Finally, we will take a look at his attitude towards those who not share his vision, which exemplifies the less appealing aspects of his thought.  相似文献

Three studies investigate how physiological emotional responses can be combined with symbolic information to predict preferences. The first study used a weighted proportional difference rule to combine explicitly quantified symbolic and emotional information. The proportion of emotion model was more predictive than a simple additive emotional (AE) combination in decisions about selecting dating partners. Study 2 showed that a simple proportion algorithm of emotionally derived weights and a simple AE model predicted preference equally well for decisions between equal expected value (EV) gambles. Study 3 provided additional evidence for decision mechanisms that combine physiological measures within symbolic trade‐off algorithms for choices between diamond rings. Self‐reported emotion measures proved to be better predictors than physiological measures. The results are discussed in the context of other major models of emotional influence on preference and provide a foundation for future research on emotional decision‐making mechanisms.
