Advances in large-scale analysis of human genomic variability provide unprecedented opportunities to study the genetic basis of susceptibility to infectious agents. We report here the use of an in vitro system for the identification of a locus on HSA8q24.3 associated with cellular susceptibility to HIV-1. This locus was mapped through quantitative linkage analysis using cell lines from multigen...

This article reports findings from two exploratory qualitative studies of the relationship between age norms, family role transitions, and the caregiving responsibilities of mothers, grandmothers, and great-grandmothers in multigeneration African American families. Families defined as having "normative on-time" transitions (n = 23) to the roles of mother, grandmother, and great-grandmother were...

Due to a variety of management specifications, hardware, firmware and software implementations, most of the cluster computing toolkits do not include remote hardware management functionalities. The remote, hardware level management is a necessary task for a computer center. The remote hardware management task requires cross-field knowledge such as specifications, management fabrics, hardware, f...

Experimental evidence indicates that non-monetary considerations influence subjects’ allocation behavior. We investigate the impact of a multigeneration setup on allocation behavior. We modify the traditional dictator game by introducing 3 generations A, B and C. A takes an arbitrary share of a pie and passes the rest to B. B divides the rest of the pie between her and C. We find that this inte...

The Adelgidae form a small clade of insects within the Aphidoidea (Hemiptera) that includes some of the most destructive introduced pest species threatening North American forest ecosystems. Despite their importance, little is known about their evolutionary history and their taxonomy remains unresolved. Adelgids are cyclically parthenogenetic and exhibit multigeneration complex life cycles. The...

Few age-structured models of species dynamics incorporate variability and uncertainty in population processes. Motivated by laboratory data for an insect and its parasitoid, we investigate whether such assumptions are appropriate when considering the population dynamics of a single species and its interaction with a natural enemy. Specifically, we examine the effects of developmental variabilit...

Self-esteem is conceptualized in terms of self-feelings that are evoked by self-evaluation of self-concept and that motivate self-enhancing or self-protective responses. Since (sub)cultural conventions and the self-esteem motive frequently invalidate self-report measures, it is argued that self-esteem should be measured as the confluence of self-evaluative statements and measures of subjective ...

The expressions for y2(t) and Y2(t) shown in Equations (11) and (12) are valid only if G2 is the latest generation available. Now suppose a generation 3 (G3) is introduced at τ3 (τ3 ≥ τ2). Similar to the shifting from G1 to G2 after τ2, some of the existing and potential adopters of G2 will consider adopting G3 after τ3. In order to derive the number of leapfrogging and switching adoptions betw...

BACKGROUND Reproductive toxicity of Atrazine (ATR) was evaluated in two rat multigenerational studies. Development of male reproductive parameters was evaluated in separate studies after prenatal or postnatal exposure. METHODS In multigenerational studies, rats received dietary concentrations of 0, 10, 50, 100 or 500 ppm ATR. In separate studies in female rats, ATR was administered by gavage ...
