Reverend Gideon Blackburn

Gideon Blackburn (1772-1838) was a Presbyterian minister, missionary to the Cherokees, church planter, college president, and anti-slavery leader. His career in the ministry was not static, owing to his drive to evangelize as well as his pioneer restlessness to move further west into the frontier. Born in Virginia, Blackburn and his family moved into the area of east Tennessee while he was still a youth and where he converted at age 15. Following his theological education, in 1792 Blackburn moved to the Maryville, TN, area and served as an itinerant chaplain to Tennessee militia while pastoring two churches and planting other ones for frontier settlers. Motivated by the zeal of the Second Great Awakening, Blackburn established two mission schools for Cherokee children, sponsored by the Presbyterian Church and which operated until 1810. Over the next three decades, he continued to preach and plant churches in Tennessee, Kentucky, and Illinois and served as an educator, college president, temperance agent, and abolitionist. Blackburn was a complex figure and driven man of action whose multi-faceted career was integral to the growth of America’s Christian heritage

Revolutionaries or Bargainers?: Negotiators for a New International Economic Order

This interview-based study analyzes the attitudes and negotiating behavior of 80 individuals, principally from less developed countries (LDCs), who were participants in international economic negotiations in 1976. Some of the more important findings are: (1) negotiators' views are more diverse than analyses of roll-call votes would indicate; (2) the positions that countries take appear to be firmly grounded in national political processes and in pragmatic conceptions of their national interests; (3) negotiators from LDCs with higher per capita GNP are more likely than those from LDCs with lower per capita GNP to perceive the negotiations as being polarized, to regard social issues as important elements of development strategies, and to take advantage of regional cooperation in negotiating; they are less likely to have negative views toward transnational corporation

The prevalence and distribution of the amyloidogenic transthyretin (TTR) V122I allele in Africa

Transthyretin (TTR) pV142I (rs76992529-A) is one of the 113 variants in the human TTR gene associated with systemic amyloidosis. It results from a G to A transition at a CG dinucleotide in the codon for amino acid 122 of the mature protein (TTR V122I). The allele frequency is 0.0173 in African Americans

Genetic and environmental influences on sleep quality in middle‐aged men: a twin study

Poor sleep quality is a risk factor for a number of cognitive and physiological age-related disorders. Identifying factors underlying sleep quality are important in understanding the etiology of these age-related health disorders. We investigated the extent to which genes and the environment contribute to subjective sleep quality in middle-aged male twins using the classical twin design. We used the Pittsburgh Sleep Quality Index to measure sleep quality in 1218 middle-aged twin men from the Vietnam Era Twin Study of Aging (mean age = 55.4 years; range 51-60; 339 monozygotic twin pairs, 257 dizygotic twin pairs, 26 unpaired twins). The mean PSQI global score was 5.6 [SD = 3.6; range 0-20]. Based on univariate twin models, 34% of variability in the global PSQI score was due to additive genetic effects (heritability) and 66% was attributed to individual-specific environmental factors. Common environment did not contribute to the variability. Similarly, the heritability of poor sleep-a dichotomous measure based on the cut-off of global PSQI>5-was 31%, with no contribution of the common environment. Heritability of six of the seven PSQI component scores (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, and daytime dysfunction) ranged from 0.15 to 0.31, whereas no genetic influences contributed to the use of sleeping medication. Additive genetic influences contribute to approximately one-third of the variability of global subjective sleep quality. Our results in middle-aged men constitute a first step towards examination of the genetic relationship between sleep and other facets of aging.Accepted manuscrip

Formal deformations, contractions and moduli spaces of Lie algebras

Jump deformations and contractions of Lie algebras are inverse concepts, but the approaches to their computations are quite different. In this paper, we contrast the two approaches, showing how to compute jump deformations from the miniversal deformation of a Lie algebra, and thus arrive at the contractions. We also compute contractions directly. We use the moduli spaces of real 3-dimensional and complex 3 and 4-dimensional Lie algebras as models for explaining a deformation theory approach to computation of contractions.Comment: 27 page
