The specific action of different personality risk factors on cancer of the breast, cervix, corpus uteri and other types of cancer: A prospective investigation

We report the results of a prospective study of a random sample of 1353 elderly but healthy men and women who were followed up for a period of 10 yr, when mortality and cause of death were ascertained. Overall results have been reported elsewhere for mortality from cancer, coronary heart disease and other causes; here we are concerned with the personality factors predicting breast cancer, cervical cancer, cancer of the corpus uteri specifically, as well as other types of cancer in women. Ten specific hypotheses were tested, using specially constructed questionnaires for the purpose, and for most of these statistically significant support was obtained. The results justify belief that specific types of cancer may be related to specific stress/personality factors.     

My place,your place,and no place: Behavior settings as a risk factor for HIV-related injection practices of drug users in Baltimore,Maryland

Information is sparse on the social context of illicit drug injection behaviors and their relationship to HIV infection. This study examined relationships between injection settings, injecting with others, and HIV risk behaviors of sharing needles and not cleaning contaminated needles in a sample of 630 inner-city injecting drug users in Baltimore, MD. Through open-ended interviews, five primary settings of injection behavior were identified. These settings included one's own, friends' and mother's residence, shooting galleries, and semipublic areas. Most participants reported injecting in their own residence (92%) and friends' residence (86%) in the prior 6 months. In a multiple regression analysis, injecting at friends' residence, in shooting galleries, and in semipublic areas and frequency of injecting with others were significantly associated with frequency of sharing uncleaned needles, “slipping” (i.e., failure to disinfect shared needles), and not always cleaning used needles before injecting. Results suggest that interventions may benefit from targeting settings as well as behaviors to reduce the spread of HIV. This research was supported by grants DA04334, DA05911, DA06313, and DA08985 from the National Institute on Drug Abuse.     

Long term marriages in Sweden: And some comparisons with similar couples in the United States

This international, five-country long term marriages study of couples who have been married, or unmarried and cohabiting, for 20 years or longer is designed to study, among other things, marital satisfaction. This first report of the Swedish part of the study reports on a Swedish version of the self-rating Dyadic Adjustment Scale (DAS) used to investigate self-rated marital satisfaction. The couples describe high marital satisfaction and a high sense of coherence (SOC) compared to other groups. Contrary to other studies, no differences were found between men and women regarding SOC. The differences between them, that describe high relative to low marital satisfaction, pertain to matters of recreation, sex, life philosophy, time spent together, and frequency of quarrels. The men reported greater marital satisfaction than the women.     

Procedural dependence in action memory: Effects of verb form and individual vs group conditions

Two experiments explored whether the magnitude of the enactment effect in action memory (i. e., higher recall with motor than with non-motor encoding) may depend upon the use of individual or group testing procedures. Nonmotor encoding instructions, requiring the subjects to listen to orally presented action items, were compared to instructions which also required enactment. With encoding treated as a within-subject factor, the observations failed to reveal any significant difference between individual and group testing. With encoding treated as a between-subject factor, the results showed an interaction between test and encoding conditions, such that an enactment effect was found only with group testing. Different support value for auditory cues in group and individual test situations was assumed to account for this difference. In a third experiment the indicative and imperative verb forms were compared. An interaction was observed, showing that in Norwegian, enacted verbs were remembered better when presented in the indicative than in the imperative. No corresponding difference was found under non-enactment conditions. For this finding, a social interaction interpretation was offered.     

Latent roots of random data correlation matrices with squared multiple correlations on the diagonal: A monte carlo study

In order to make the parallel analysis criterion for determining the number of factors easy to use, regression equations for predicting the logarithms of the latent roots of random correlation matrices, with squared multiple correlations on the diagonal, are presented. The correlation matrices were derived from distributions of normally distributed random numbers. The independent variables are log (N–1) and log {[n(n–1)/2]–[(i–1)n]}, whereN is the number of observations;n, the number of variables; andi, the ordinal position of the eigenvalue. The results were excellent, with multiple correlation coefficients ranging from .9948 to .9992.This research was supported by the Office of Naval Research under Contract N00014-67-A-0305-0012, Lloyd G. Humphreys, principal investigator, and by the Department of Computer Science of which Richard G. Montanelli, Jr., is a member.     

Comments on “the measurement of factorial indeterminacy”

Guttman's index of indeterminacy (2² – 1) measures the potential amount of uncertainty in picking the right alternative interpretation for a factor. When alternative solutions for a factor are equally likely to be correct, then the squared multiple correlation ² for predicting the factor from the observed variables is the average correlation _AB between independently selected alternative solutionsA andB, while var ( _AB )=(1 – ²)²/s, wheres is the dimensionality of the space in which unpredicted components of alternative solutions are to be found. When alternative solutions for the factor are not equally likely to be chosen, ² is the lower bound for E( _AB ); however, E( _AB ) need not be a modal value in the distribution of _AB . Guttman's index and E( _AB ) measure different aspects of the same indeterminacy problem.     

环境因素与成人认知关系的研究

本研究旨在考察环境因素与认知发展的关系.采用问卷和心理测量的方法对121名21～80岁成人被试的基本认知能力和环境影响变量进行测量.结果发现,在基本认知能力上存在显著的年龄差异;在环境测量的环境维度因素方面仅出现年龄差异,而环境测量的休闲维度因素方面却存在显著的年龄和性别双重差异;多项环境因素与基本认知能力存在显著相关.结论老年人基本认知能力低于年轻被试,且环境因素对认知发展有一定影响.

2004至2016年中国大学生身体自尊的变迁:一项横断历史研究

大学生身体自尊是如何随年代变化的呢？研究对2004年至2016年107篇使用身体自尊量表的研究进行了横断历史研究,涉及大学生30738名。结果显示：（1）我国大学生身体自我价值感、运动能力和身体素质与年代有着显著正相关关系;（2）男女大学生身体自尊水平都有了一定提升;（3）男生在身体自尊各个因子的得分高于女生0.2~0.3个标准差,显示出了大学生在身体自尊水平上的性别差异;（4）从大学生整个群体来看,经济因素、高等教育因素与大学生身体自尊具有显著相关,而从不同性别群体来看,经济因素与人口压力对于男大学生的身体自尊影响更为明显。
