SummaryNucleosome filaments of two stages of the life-cycle of Trypanosoma brucei brucei, namely bloodstream forms and procyclic culture forms, were investigated by electron microscopy. Chromatin of bloodstream forms showed a salt-dependent condensation. The level of condensation was higher than that shown by chromatin from procyclic culture forms, but 30 nm fibres as formed in rat liver chromatin preparations were not found. Analysis of histones provided new evidence for the existence of H1-like proteins, which comigrated in the region of the core histones in SDS–PAGE and in front of the core histones in Triton acid urea gels. Differences were found between the H1-like proteins of the two trypanosome stages as well as between the core histones in their amount, number of bands and banding pattern. It can be concluded that T. b. brucei contains a full set of histones, including H1-like proteins, and that the poor condensation of its chromatin is not due to the absence of H1, but most probably due to histone–DNA interaction being weak. It is obvious that structural and functional differences of the chromatin exist not only between T. b. brucei and higher eukaryotes, but also between various stages of the life-cycle of the parasite. It is therefore not adequate to investigate the chromatin only of the procyclic culture forms as a model for all stages of the life-cycle of T. b. brucei.

AbstractOur research presents new evidence on the age pattern of the implicit value of life revealed from workers' differential wages and job safety pairings. Although aging reduces the number of years of life expectancy, aging can affect the value of life through an effect on planned life-cycle consumption. The elderly could, a priori, have the highest implicit value of life if there is a life-cycle plan to defer consumption until old age. We find that largely due to the age pattern of consumption, which is non-constant, the implicit value of life rises and falls over the lifetime in a way that the value for the elderly is higher than the average over all ages or for the young. There are important health policy implications of our empirical results. Because there may be age-specific benefits of programs to save statistical lives, instead of valuing the lives of the elderly at less than the young, health policymakers should more correctly value the lives of the elderly at as much as twice the young because of relatively greater consumption lost when accidental death occurs.

Special education teachers are expected to fulfill diverse teaching and nonteaching tasks in comparison to their general education peers. However, their performance is evaluated with measures that were normed for use with general education teachers. These specialty teachers are also routinely evaluated by professionals who may lack formal special education training or experience. These conditions render special educators vulnerable for inaccurate performance evaluation. Explicit research is needed to clarify the professional skills that are most critical to special educators’ professional effectiveness and ensure continuity of focus on these skills in preservice teacher education and employment contexts. This qualitative study builds on an earlier empirical investigation that demonstrated consensus among three sets of professionals that the standards developed by Council for Exceptional Children’s (CEC) represented skills that are critical for special education teacher effectiveness. The current study describes which skill domains were identified as critical for special education teacher effectiveness across participant groups and those that reflected distinct groups’ perspectives. Implications for future research are presented relative to strategies to more clearly articulate special education teacher expertise and ways to strengthen continuity across preservice special education teacher education and in-service professional development contexts.

Retirement Status

AbstractForeseeable income reductions around retirement should not affect aggregate consumption. However, given higher leisure endowments after retirement, theory also predicts lower consumption of leisure substitutes. To avoid misinterpreting this predicted drop as a puzzle, our novel approach focuses on housing consumption (complementary to leisure in utility) and controls for leisure changes. In Germany tenants represent roughly half of all households, making many housing expenditures directly observable in micro data. We find significant negative impacts of the retirement status on housing consumption, which is hard to reconcile with life-cycle theory. Despite the lock-in nature of past housing decisions, income reductions at retirement have additional – though small – effects on housing.
