Anecdotal evidence suggests that young people use the website Twitter as a tool to warn drivers about the locations of sobriety checkpoints. Researchers investigated this claim by independently analyzing the website's content regarding a sample of 10 sobriety checkpoints that were conducted in cities throughout the United States during the weekend…

This study reported mother-daughter agreement on adolescent adopted Chinese girls' adjustment. Data on the girls' academic performance and internalizing syndromes were collected from the adopted Chinese girls and their adoptive mothers separately.

One fundamental aspect of engagement in higher education is faculty-student interaction (FSI). FSI has been associated with student success and persistence in both four- and two-year institutions. Due to limited research concerning diverse students, understanding student engagement in higher education is based on White, traditional-age students…

Extensive support for the seemingly paradoxical negative effects of school- and class-average achievement on academic self-concept (ASC)-the big-fish-little-pond effect (BFLPE)--is based largely on secondary students in Western countries or on cross-cultural Program for International Student Assessment studies. There is little research testing the…

To study implicit concepts of creativity in computer science in the United States and mainland China, we first asked 308 Chinese computer scientists for adjectives that would describe a creative computer scientist. Computer scientists and non-computer scientists from China (N = 1069) and the United States (N = 971) then rated how well those…

This paper presents a comprehensive analysis of the link between age and proficiency in information-processing skills, based on information drawn from the Survey of Adult Skills (PIAAC). The data reveal significant age-related differences in proficiencies, strongly suggesting that proficiency tends to "naturally" decline with age. Age…

The present study examined adult age and sex differences in self-reported aspirations and personal meaning. Young, midlife, and older adults (N = 2,557) from the United Kingdom or United States completed an online survey of their aspiration striving, aspiration importance, and personal meaning (subscales of Purposeful Life, Exciting Life,…

This article seeks to make sense of the seeming contradiction that the number of degrees awarded annually and the attainment rate of the adult population in the US have both grown, even as the country has fallen behind many global competitors on the latter indicator. Two reports issued in 2012---one by the Pew Research Center, the other by the…

A longitudinal study of U.K. journalism undergraduates records how their attitudes on societal roles of the news media changed during university education. Students became more likely to endorse an adversarial approach toward public officials and businesses as extremely important. Yet students did not support these roles as strongly as an older…

The present study addresses women's underrepresentation in the academic profession, as well as the need for policies and practices aimed at this issue. It compares underrepresentation of academic women in North American countries, and explores, throughout a bivariate analysis, personal, professional, as well as institutional variables related to…

We use hierarchical cross-classified random-effects models to simultaneously measure age, period, and cohort patterns of mortality risk between 1986 and 2006 for non-Hispanic white and non-Hispanic black men and women with less than a high school education, a high school education, and more than a high school education. We examine all-cause…

Citizen science, in which volunteers work with professional scientists to conduct research, is expanding due to large online datasets. To plan projects, it is important to understand volunteers' motivations for participating. This paper analyzes results from an online survey of nearly 11000 volunteers in Galaxy Zoo, an astronomy citizen science…

In recent years, increasing numbers of grandparents in the U.S. are living with their grandchildren, and many grandparents are responsible for their care. These trends can be attributed to a number of factors, including increasing numbers of single-parent families, continued high rates of marriage dissolution, parents' incarceration, parental…

Children and youth who participate in out-of-school-time (OST) programming are more likely than their non-participating peers to do well in school, get sufficient physical exercise, and avoid involvement in risky behaviors. However, there are concerns that there are inequities in access to OST programs, particularly for those from lower-income…

Method: Data for 2,191 Korean children (211 children recruited "offline" through preschools, and 1,980 recruited "online" via the Internet) and 274 U.S.…
