Learning to kill: Why a small handful of counties generates the bulk of US death sentences.

We demonstrate strong self-referential effects in county-level data concerning use of the death penalty. We first show event-dependency using a repeated-event model. Higher numbers of previous events reduce the expected time delay before the next event.

Relation entre la mastication et la qualité de l'alimentation des aînés de l'Étude longitudinale québécoise sur la nutrition et le vieillissement (NuAge).

The objective of this study was to assess the relationship between the quality of mastication and dietary intake among community-dwelling older adults (67-84 years). A secondary analysis of data collected upon entry of participants in the NuAge study was effected. Perceived masticatory efficiency (n=1793) was measured using a questionnaire inspired by the Oral Health Impact Profile.

Assessing Older Adults' Masticatory Efficiency.

Objectives: To determine internal consistency and criterion validity of a questionnaire assessing perception of masticatory efficiency in community-dwelling older adults.

Design: Secondary cross-sectional analysis of baseline data from the Québec Longitudinal Study on Nutrition and Successful Aging (NuAge).

Setting: NuAge is a 5-year (2003-08) observational study of 1,793 men and women aged 67 to 84 in good general health at recruitment.

Adiposity and gingival crevicular fluid tumour necrosis factor-alpha levels in children.

Aim: To investigate whether adiposity is associated with gingival crevicular fluid (GCF) tumour necrosis factor-alpha (TNF-alpha) levels in children. We also examined whether this relationship is mediated through plasma fasting insulin.

Materials And Methods: This preliminary study used cross-sectional data from the baseline-visit of the Quebec Adipose and Lifestyle InvesTigation in Youth cohort, which is an ongoing longitudinal study investigating the natural history of obesity in Quebec children.
