Latino college students (M age=21.4 years) completed self-report surveys assessing adolescent dating experiences. Compared to young men (n=69), young women (n=97) had more limitations placed on them by parents as adolescents and began dating later. No gender difference in timing of the first serious relationship emerged. More young women had their first relationship with a Latino, and having a ...

This paper examines how the use of various taxonomic levels and morphological functional groups influences the interpretation of multivariate analyses when comparing macroalgal assemblages in different regions in the Northeast Pacific. We found that for intertidal assemblages, within-site variation was high at the species level and regions only became discernable from the genus level to the ord...

BACKGROUND To explain the historically low rates of participation in cancer clinical trials, several factors have been studied. These include subject characteristics and attitudes, clinical trial availability and eligibility criteria, and physician attitudes and communication skills. However, the impact of nonphysician research personnel, who often consent patients for studies, is unclear. We t...

BACKGROUND The persistence of knee pain (KP) and its relationship with occupational factors were investigated in two prospective cohorts of French workers: retirees of the Gazel cohort and workers in the Cosali cohort. METHODS KP was defined according to the Nordic questionnaire (>1 day in the last year), and the information was extracted from two questionnaires in 2006 and 2012 for the Gazel...

514 men and 891 women college students provided information concerning behaviors both they and their partners used within the prior six months to resolve conflicts in their relationships. Multivariate analyses assessed whether experiencing the divorce of one's parents would be associated with respondents' report of their own or their partners' conflict behaviors. Students from divorced families...

In this paper, we introduce a new multivariate Weibull (MVW) distribution with many interesting properties. We obtain the maximum likelihood estimate (MLE) of the parameters and their asymptotic multivariate normal (AMVN) distribution in MVWmodel. We propose large sample studentized tests for testing multivariate exponentiality and also tests for independence and identical marginals of the comp...

It has been proposed that imagining the future depends on the ability to retrieve episodic details from past experiences in order to recombine them into novel possible experiences; consequently, the processes of remembering and imagining rely on similar neural substrates, including the hippocampus. We used fMRI and both univariate and multivariate analysis techniques to test this prediction. Un...

PURPOSE This study was designed to track trends in reports of unwanted sexual solicitations, harassment, and unwanted exposure to pornography via the Internet between 2000 and 2005 across various demographic sub-groups of youth. METHODS Cross-sectional data was collected in two equivalent national telephone surveys of 1500 Internet users, ages 10 through 17 years. Bivariate and multivariate a...

the study was carried out in the ilam oak forest that is located in the west part of iran. the objective of this research was to determine the plant ecological groups and site classification in this region. data were collected from 117 sample plots using the systematic-random sampling method. the size of sampling plots was 20 m?20 m for the tree and shrub species and 1.5 m ?1.5 m for herbaceous...

ground vibrations caused by blasting are undesirable results in the mining industry and can cause serious damage to the nearby buildings and facilities; therefore, controlling such vibrations has an important role in reducing the environmental damaging effects. controlling vibration caused by blasting can be achieved once peak particle velocity (ppv) is predicted. in this paper, the values of p...
