On the nature of isolated and post-isolated dialects: Innovation, variation and differentiation

The investigation of two historically isolated communities in the United States, Smith Island, Maryland, and the Lumbee Native American community in Robeson County, North Carolina, demonstrates that, contrary to assumption, isolated communities may be linguistically innovative and heterogeneous. Explanations are both cognitive and social. Speakers in isolated communities are not subject to the leveling pressure that comes with exposure to heterogeneous usage norms and so are free to retain intra-dialectal variation and carry through internal innovations. In addition, the close-knit networks that characterize isolated communities allow for the transmission of intricate patterns of intra-community variation, while the inward focus of such communities heightens the social semiotic importance of this variation. The present study also shows that as communities emerge from historic isolation, they do not necessarily succumb to leveling pressure. Instead, speakers' desire to retain cultural distinctiveness may enable them to retain and even enhance their linguistic distinctiveness.     

Physical activity and cognitive-health content in top-circulating magazines, 2006-2008

Physical activity may promote cognitive health in older adults. Popular media play an important role in preventive health communication. This study examined articles discussing associations between physical activity and cognitive health in top-circulating magazines targeting older adults. 42,753 pages of magazines published from 2006 to 2008 were reviewed; 26 articles met inclusion criteria. Explanations regarding the link between physical activity and cognitive health were provided in 57.7% of articles. These explanations were generally consistent with empirical evidence; however, few articles included empirical evidence. Physical activity recommendations were presented in 80.8% of articles; a wide range was recommended (90-300 min of physical activity per wk). Socioeconomic status and education level were not mentioned in the text. Results suggest an opportunity for greater coverage regarding the role of physical activity in promoting cognitive health in popular media. Magazine content would benefit from including more empirical evidence, culturally sensitive content, and physical activity recommendations that are consistent with U.S. guidelines.     

As the population clock winds down: Indicative effects of population ageing in Australia’s States and Territories

Among the more profound features of population ageing is its regionality. This regionality is particularly marked in Australia, where the timing and speed of ageing are occurring at substantially different rates by state and territory. The shift to natural decline is expected to create many social, economic and political predicaments where it is first experienced. In Australia, Tasmania will be the first to enter natural decline, followed soon thereafter by South Australia, but not for several years by the youngest states and territories. These diverging demographic forces will have many implications for the complex mixture of federal, state and local government that currently adjudicates over policy-making and implementation, especially concerning the collection of taxes, the distribution of the goods and services of the Welfare State, and a large element of fiscal redistribution. This paper provides an overview of demographic characteristics and dynamics by region, and examines their projected effects on three socio-economic indicators: educational demand, the labour market, and demand for Age Pensions. The changing demography will have both beneficial and adverse affects, and unless the profound regionality is soon understood and engaged with, currently older and younger states are likely to encounter not only diverging demographic forces, but also diverging fortunes.     

Together They Become One: Examining the Predictors of Panethnic Group Consciousness Among Asian Americans and Latinos*

Objective. This article examines panethnic consciousness as it applies to the two fastest‐growing minority groups in the United States: Asian Americans and Latinos. Given the challenges of diversity and immigration faced by these two communities, I examine the individual‐level factors that help strengthen their panethnic group identity. Methods. Drawing from data provided by the 2000 Pilot National Asian American Political Survey and the 1999 National Survey on Latinos, I use ordered probit models to determine the predictors of panethnic consciousness among both Asian Americans and Latinos. Results. The models confirm that for Asian Americans, high income, involvement in Asian‐American politics, being a Democrat, and the role of racial discrimination encourage panethnic consciousness. For Latinos, the important factors are higher levels of education, gender, being foreign born, involvement in Latino politics, and perceptions of discrimination. Conclusions. The findings here stress the importance of social contextual factors such as racial discrimination on the formation of panethnic identity.     

A Proportional Odds Beta-Binomial Model for Evaluating the Effect of Treatment in Cross-Over Studies with Baseline Covariates: An Application to Condom Failure Data

Cross-over trials with correlated Bernoulli outcomes are common designs. In condom functionality studies, for example, an indicator of condom failure is reported for each sex act using standard or experimental condoms. Two popular analysis methods for such data are Generalized Estimating Equations and logit-normal random effects models. An alternative random effects model, the beta-binomial, is commonly used in contexts involving only between-cluster effects. The flexibility of the beta distribution and the interpretation of random effects as cluster-specific failure probabilities make it appealing, and we consider an extension of the model to account for within-cluster treatment effects using proportional odds assumptions.     

Sensitive research with adolescents: just how upsetting are self-report surveys anyway?

Distress related to answering personal survey questions about drug use, suicidal behavior, and physical and sexual abuse were examined in multiple convenience samples of adolescents. Samples varied in consent procedures utilized (active vs. passive parental consent), data collection setting (school vs. juvenile justice), developmental level (middle school vs. high school). Participation rates differed across consent procedures (e.g., 93% with passive vs. 62% with active parental consent). Results indicated that small percentages of adolescents in every sample reported frequently feeling upset while completing the survey (range 2.5% to 7.6%). Age, race, gender, and data collection strategy did not emerge as significant predictors of feeling upset. Instead, as hypothesized, adolescents reporting a history of suicidal ideation or attempt, illicit drug use, or experiences of physical or sexual victimization endorsed more frequent feelings of upset while completing the survey than peers without these experiences. Taken together, however, these sensitive event experiences explained only 6.6% of the variance in adolescents' upset ratings. The scientific and ethical implications of these findings are discussed with regard to adolescent participation in survey research about sensitive topics.
