Interpersonal Perceptions of Narcissism in an At‐Risk Adolescent Sample: A Social Relations Analysis 下载免费PDF全文
Sarah J. Grafeman Christopher T. Barry David K. Marcus Lacey L. Leachman 《Journal of research on adolescence》2015,25(1):92-100
This study utilized Kenny's social relations model (SRM) to explore the interpersonal correlates of narcissism in an adolescent sample from a voluntary residential program. Participants were forty‐seven 16–18‐year‐olds (24 males, 23 females) attending a 22‐week residential program. Participants completed a self‐report measure of narcissism and rated one another on narcissism‐related traits and social status variables. Individuals with high levels of self‐reported narcissism were perceived by peers as antagonistic and likely to engage in future delinquency. Self‐reported narcissism was also associated with peer perceptions of narcissism‐related traits. Therefore, adolescent narcissism seems to be detected by peers and is associated with peer perceptions of some negative qualities. Potential implications of these findings are discussed. 相似文献

The effects of changes in rates of mortality, fertility, and migration depend not only on the age-specific patterns and levels
of these rates, but on the age structure of the population. In order to remove the influences of the age structure and concentrate
on the effects of the demographic rates themselves, a common practice is to analyze the influences of the rates for a standard
age structure. This paper analyzes current and future population changes in Germany, using a stationary population equivalent
model (SPE) that shows long-term effects of current fertility, mortality, and international migration patterns. Results indicate
that the German population will eventually decline because of below replacement fertility, if net immigration does not counteract
this decrease. This means, for instance, that the long-term stationary population levels for Germany will decrease by approximately
6.5 million during a decade in which current fertility, mortality, and international migration levels prevail. The paper also
reports how various other assumptions for mortality, fertility, and international migration affect the SPE model for Germany. 相似文献

In this paper the theory of the generalized F variate is examined. A large class of statistics is constructed for linear for linear models when the errors are distributed N(0, ∑), where ∑ is positive definite. These statistics are shown to have a generalized F distribution. The role of the generalized F variate is then studied in detail for a linear model of constant intraclass correlation. 相似文献

We are interested in comparing logistic regressions for several test treatments or populations with a logistic regression for a standard treatment or population. The research was motivated by some real life problems, which are discussed as data examples. We propose a step-down likelihood ratio method for declaring differences between the test treatments or populations and the standard treatment or population. Competitors based on the sequentially rejective Bonferroni Wald statistic, sequentially rejective exact Wald statistic and Reiers?l's statistic are also discussed. It is shown that the proposed method asymptotically controls the probability of type I error. A Monte Carlo simulation shows that the proposed method performs well for relatively small sample sizes, outperforming its competitors. 相似文献

This article presents a Bayesian approach to the regression analysis of truncated data, with a focus on zero-truncated counts from the Poisson distribution. The approach provides inference not only on the regression coefficients but also on the total sample size and the parameters of the covariate distribution. The theory is applied to some illegal immigrant data from The Netherlands. Several models are fitted with the aid of Markov chain Monte Carlo methods and assessed via posterior predictive p-values. Inferences are compared with those obtained elsewhere using other approaches. 相似文献

A procedure is developed to test the equality of the quantiles from k populations, assuming the responses follow a two-parameter binary model.The method utilizes the asymptotic distribution of the maximum likelihood estimators.The exact distribution of the test statistic is discussed in general.This exact distribution is generated for the logit model in order to investgate the convergence properties of the asymptotic procedure. 相似文献

Jennlson and Turnbull (1984,1989) proposed procedures for repeated confidence intervals for parameters of interest In a clinical trial monitored with group sequential methods. These methods are extended for use with stochastic curtailment procedures for two samples in the estimation of differences of means, differences of proportions, odds ratios, and hazard ratios. Methods are described for constructing 1) confidence intervals for these estimates at repeated times In the course of a trial, and 2) prediction intervals for predicted estimates at the end of a trial. Specific examples from several clinical trials are presented. 相似文献
