The hypothalamic‐pituitary‐adrenal (HPA) axis, including its regulation of cortisol, is central to bodily functioning and salivary cortisol is a commonly used biomarker that reflects the functioning of the HPA axis. However, knowledge of diurnal cortisol rhythms in healthy adolescents is limited and few studies have examined patterns in midadolescent girls and boys across single and aggregate cortisol measures. To fill this gap, the present study investigated single and aggregate cortisol measures reflecting diurnal rhythms in 14 to 16‐year‐old girls and boys. Self‐administered salivary samples from 79 girls and 42 boys were collected during two schooldays at four timepoints: (a) immediately at awakening, (b) 30 min after waking up, (c) 60 min after waking up, and (d) at 8:00 p.m. Additionally, diary data including time of awakening, sampling times, and other potential confounders were analyzed. As for single measures, both girls and boys exhibited a typical diurnal cortisol profile with high levels in the morning that decreased throughout the day. However, girls had higher morning cortisol than did boys with significant differences at time of awakening, and at 30 and 60 min postawakening. For the aggregate measures, girls had a larger total level of cortisol in terms of cortisol awakening response (CARG), area under the curve (AUCG), and rise over run (slopeawake to last), while no differences emerged for reactivity measures. Taken together, these findings suggest differences in single and aggregate cortisol measures between midadolescent girls and boys. Such differences in diurnal cortisol between pubertal girls and boys may play a role for the differential health trajectories typically found among adult women and men. 相似文献

This study presents results of a nation-wide survey of 348 mail-order and adult shop purchasers of X-rated videos in Australia. The sample was drawn from those who purchased X-rated videos from a nation-wide distributor in late 1992. The sociodemographic profile, consumption history, viewing habits, and uses of the X-rated videos by the consumers are discussed. The findings are presented as an initial attempt to study the regular consumers of pornographic videos in a country with a standardized censorship system which regulates the content of X-rated videos. The results are also examined in the light of previous theoretical and empirical examinations of the purchasers and consumers of X-rated videos in relation to issues of criminalization. 相似文献

According to the theoretical framework relating hypnosis to attention, baseline attentional functioning in highly hypnotizable individuals should be more efficient than in low hypnotizable individuals. However, previous studies did not find differences in Stroop-like tasks in which the measure indicative of the Stroop interference effect was based on response latencies. This study was designed to determine whether subjects with different levels of hypnotic susceptibility show differences in baseline attentional functioning. To assess this hypothesis, high, medium, and low hypnotizable subjects performed a Stroop task designed to evaluate accuracy performance, before being subjected to hypnotic induction. Results showed that the Stroop interference effect was smaller in high hypnotizable subjects than in low hypnotizable subjects, whereas it was not different between high, and medium hypnotizable subjects. This outcome supports the notion that baseline attentional functioning is related to hypnotic susceptibility. 相似文献

By solving the problem of a periodic distribution of point defects in general anisotropic media, we give an alternative, more direct proof, of the relatively recent procedure that extracts dipole tensors from the stress acting on the cell of atomistic simulations performed under periodic boundary conditions. Moreover, we show that naive superposition of individual defect fields is not a solution of the problem, though correction terms can be identified; as a byproduct, analysis of the latter allows us to reveal a spurious contribution to the elastic interaction energy as calculated in current literature procedures, that therefore must be subtracted in order to obtain correct results. 相似文献

This article analyses the influence of accent on discrimination against immigrants by examining the hypothesis that accent leads to discrimination only in more prejudiced individuals, merely because people speaking with a native accent are perceived to be better qualified than those whose accent is non‐standard. In Study 1 (N = 71), we found that only prejudiced individuals use accent to discriminate against immigrants. In Study 2 (N = 124), we replicated this effect and found that the influence of accent on discrimination is mediated by the perceived quality of the accent. Study 3 (N = 105) replicated the previous results even after controlling for the effect of stereotyping. These results are the first experimental illustration of the hypothesis that accent triggers intergroup discrimination only among prejudiced individuals because they evaluate native accents as being qualitatively better than accents of immigrants, thereby legitimizing ingroup bias. 相似文献

This is the text of a conversation that follows up on Roberto Farneti??s article ??A Minor Philosophy: The State of the Art of Philosophical Scholarship in Italy?? published in Philosophia 38 (1) 2009: 1?C28. After a brief introductory note that details the reception of the article in Italy, Ferrara and Farneti engage in a conversation on the notion of ??minor philosophy?? and on the meaning and future of philosophizing ??from the periphery?? in a globalized world. The text is followed by a short Appendix, a reply to Annalisa Coliva??s commentary on Farneti??s article. 相似文献

Confirmation of a hypothesis by evidence can be measured by one of the so far known incremental measures of confirmation.
As we show, incremental measures can be formally defined as the measures of confirmation satisfying a certain small set of
basic conditions. Moreover, several kinds of incremental measure may be characterized on the basis of appropriate structural
properties. In particular, we focus on the so-called Matthew properties: we introduce a family of six Matthew properties including
the reverse Matthew effect; we further prove that incremental measures endowed with reverse Matthew effect are possible; finally,
we shortly consider the problem of the plausibility of Matthew properties. 相似文献

The paper presents the field of Visual Sociology as an approach that makes use of photographs, films, documentaries, videos, to capture and assess aspects of social life and social signals. It overviews some relevant works in the field, it deals with methodological and epistemological issues, by raising the question of the relation between the observer and the observed, and makes reference to some methods of analysis, such as those proposed by the Grounded Theory, and to some connected tools for automatic qualitative analysis, like NVivo. The relevance of visual sociology to the study of social signals lies in the fact that it can validly integrate the information, introducing a multi-modal approach in the analysis of social signals. 相似文献
