An age-period-cohort analysis of cancer incidence among the oldest old, Utah 1973-2002.

We used age-period-cohort (APC) analyses to describe the simultaneous effects of age, period, and cohort on cancer incidence rates in an attempt to understand the population dynamics underlying their patterns among those aged 85+. Data from the Utah Cancer Registry (UCR), the US Census, the National Center for Health Statistics (NCHS), and the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) programme were used to generate age-specific estimates of cancer incidence at ages 65-99 from 1973 to 2002 for Utah. Our results showed increasing cancer incidence rates up to the 85-89 age group followed by declines at ages 90-99 when not confounded by the separate influences of period and cohort effects.

Fractals, Vigilance, and Adolescent Diabetes Management: A Case for When Regulation May Be Difficult to Measure With the Current Medical Standards.

Temporal patterning in blood glucose (BG) consistent with fractals-how BG follows a repetitive pattern through resolutions of time-was used to examine 2 different samples of adolescents with Type 1 diabetes (10-14 years). Sample 1 contained 10 adolescents with longtime series for accurate estimations of long-term dependencies associated with fractals. The second contained 94 adolescents measured multiple times daily over a 2-week period corresponding to psychosocial measures.

Defensive pessimism, self-esteem instability, and goal strivings.

Defensive pessimism (Norem & Cantor, 1986a) is conceived as an adaptive motivational strategy employed in academic contexts. The present research investigates some potentially deleterious correlates of the defensively pessimistic strategy. We examined the hypothesis that defensive pessimists would have a relatively high ratio of negative-to-positive academically relevant self-thoughts, and these accessible thoughts would be related to high self-esteem instability.

"Having a girlfriend without knowing it".

Abstract This article provides a qualitative analysis of the intimate friendships of 80 adolescent and young adult sexual-minority women who were interviewed as part of an ongoing longitudinal study. Many reported having participated in a same-sex best friendship that they considered as committed, intimate, passionate, and intense as a romantic relationship. These "passionate friendships" typically combined components of the normative heterosexual friendship script with components of the normative romantic relationship script.
