The conceptualization of sex as a status characteristic has been recently advanced (Meeker & Weitzel-O'Neill, 1977) as an explanatory principle for the apparently inconsistent findings regarding the relationship between sex and role specialization (e.g., the task/expressive distinction). This study is concerned with the validity of sex-as-status hypothesis and its potential generality examined in the context of research on locus of control. It is argued that sex differences in this variable may represent a special case of a more general pattern of relationships between status differentiations and locus of control. Conceived as realistic responses to position in the social hierarchy, beliefs in internal control are expected of higher status persons, while an external orientation is anticipated for individuals of lower status. This proposition has been empirically tested in a sample of Israeli college students. The findings lend support to the hypothesis, showing that females' tendency to external orientation is reinforced if they come from lower-class families; correspondingly, males' a priori internal orientation is more sharply pronounced if they come from the higher social classes. The theoretical appeal of the sex-as-status hypothesis vis-à-vis some alternative perspectives is discussed.  相似文献

Burnout is characterized by emotional exhaustion, physical fatigue, and cognitive weariness, resulting from prolonged exposure to work-related stress. The authors review the accumulated evidence suggesting that burnout and the related concept of vital exhaustion are associated with increased risk of cardiovascular disease and cardiovascular-related events. The authors present evidence supporting several potential mechanisms linking burnout with ill health, including the metabolic syndrome, dysregulation of the hypothalamic-pituitary-adrenal axis along with sympathetic nervous system activation, sleep disturbances, systemic inflammation, impaired immunity functions, blood coagulation and fibrinolysis, and poor health behaviors. The association of burnout and vital exhaustion with these disease mediators suggests that their impact on health may be more extensive than currently indicated.  相似文献

This study investigated the influence of a child’s DRD4 risk, parental levels of ADHD symptoms, and the interactive influence of these factors on the development of preschool aggression. Additionally, the study investigated the role of home chaos as a mediator between parental ADHD symptoms and child aggression. The sample consisted of 84 4.5-year-old children and their parents. Children were genotyped for the DRD4 polymorphism. ADHD symptoms were self-reported by parents when the child was 2 to 6 months old. Parental reports of home chaos and the child’s aggression were collected 4 years later. Child’s DRD4 risk and parental ADHD symptoms significantly contributed to the prediction of preschool aggression. However, contrary to our hypotheses, no interactions were found between the child’s DRD4 risk and the levels of parental ADHD symptoms. Home chaos played a mediating role in the relation between paternal ADHD symptoms and the child’s aggression. The relation between maternal ADHD symptoms and the child’s aggression was not significantly mediated through the level of home chaos. The current study emphasizes the importance of longitudinally investigating the contribution of parental ADHD symptoms to child aggression, while also exploring the differential contribution of maternal/paternal inattention and hyperactivity-impulsivity symptoms. Moreover, home chaos was found to be a significant environmental mechanism through which paternal ADHD symptoms affect children’s aggression in the preschool years.  相似文献

Abstract

The process of anodic oxide growth has been investigated. It is shown that the obtained experimental results confirm the Fehlner-Mott oxidation model in the case of InSb, a typical compound of the 111-V group. We also present a kinetic theory of the anion migration in the formed oxide. The theory is based on the following assumptions. (a) The only species which moves through the formed oxide is the OH? anion. (b) The chemical reactions of OH? with In3+ and Sb3+ cations take place simultaneously and independently, in a thin layer of the oxide/InSb interface. The resulting solution of the kinetic equations describes the anion distribution in the formed oxide. A simple expression for the rate of oxidation is obtained. Another possible application of the presented theory is suggested.  相似文献

To better characterize fluent and nonfluent variants of primary progressive aphasia (PPA). Although investigators have recognized both fluent and nonfluent patients with PPA, the clinical and neuroimaging features of these variants have not been fully defined. We present clinical and neuropsychological data on 47 PPA patients comparing the fluent (n=21) and nonfluent (n=26) subjects. We further compared language features with PET/SPECT data available on 39 of these patients. Compared to the nonfluent PPA patients, those with fluent PPA had greater impairment of confrontational naming and loss of single word comprehension. They also exhibited semantic paraphasic errors and loss of single word comprehension. Patients with nonfluent PPA were more likely to be female, were more often dysarthric, and exhibited phonological speech errors in the absence of semantic errors. No significant differences were seen with regard to left hemisphere abnormalities, suggesting that both variants result from mechanisms that overlap frontal, temporal, and parietal regions. Of the language measures, only semantic paraphasias were strongly localized, in this case to the left temporal lobe. Fluent and nonfluent forms of PPA are clinically distinguishable by letter fluency, single word comprehension, object naming, and types of paraphasic errors. Nevertheless, there is a large amount of overlap between dysfunctional anatomic regions associated with these syndromes.  相似文献

This study reports two Hebrew-speaking individuals with acquired visual dyslexia. They made predominantly visual errors in reading, in all positions of the target words. Although both of them produced visual errors, their reading patterns crucially differed in three respects. KD had almost exclusively letter substitutions, and SF also made letter omissions, additions, letter position errors, and between-word migrations. KD had difficulties accessing abstract letter identity in single-letter tasks, and in letter naming, unlike SF, who named letters well. KD did not show lexical effects such as frequency and orthographic neighbourhood effects and produced nonword responses, whereas SF showed lexical effects, with a strong tendency to produce word responses. We suggest that these two patterns stem from two different deficits - KD has letter identity visual dyslexia, which results from a deficit in abstract letter identification in the orthographic-visual analysis system, yielding erroneous letter identities, whereas SF has visual-output dyslexia, which results from a deficit at a later stage, a stage that combines the outputs of the various functions of the orthographic-visual analyzer.  相似文献

Enuresis, one of the most prevalent and chronic childhood disorders, imposes serious financial, physical, and emotional burdens on the child and the family affected by it. This article provides counselors with an overview of the complex etiologies, diagnostic criteria, and current treatment options for the disorder, as well as assessment tools and comprehensive treatment guidelines, including instructions on the use of an enuresis alarm. Supportive interventions and advocacy related issues are discussed.  相似文献
