Role of Insects and Diseases in a Jack Pine Provenance Study

Two jack pine plantations were established at the Cloquet Forestry Center, Cloquet, Minnesota, in 1942 and 1943, using trees originating from 22 sites in the United States and 10 in Canada. From 1945 to 1953 the incidence of attack by insects and diseases was recorded individually for all trees, and in 1980-1981 the diameter and form of both living and dead trees were recorded. There were differences in the incidence of attack by the pests and in tree response to early injury among the various seed sources. In 1980 and in 1981 there were differences in tree form resulting from insect and both living and dead pest-free trees had the best form. The diameter increases from 1955 to 1980-1981 were almost identical for all categories with the exception of the dead pest-free trees which had the smallest diameters

The use of the McIlwain L-parameter to estimate cosmic ray vertical cutoff rigidities for different epochs of the geomagnetic field

Secular changes in the geomagnetic field between 1955 and 1980 have been large enough to produce significant differences in both the verical cutoff rigidities and in the L-value for a specified position. A useful relationship employing the McIlwain L-parameter to estimate vertical cutoff rigidities has been derived for the twenty-five year period

Probabilistic projections of age-specific fertility rates (1895-2040)

El objetivo del presente trabajo es modelar y pronosticar tasas de fecundidad por edad de la madre en Argentina para períodos sin datos, con base en estadísticas vitales (1980-2014), estimaciones previas disponibles parael lapso 1955-1980, censos y proyecciones de población. Para ello, a partir de modelos de series de tiempo funcionales se proyectaron y retroproyectaron las tasas de fecundidad por edad para los períodos 1895-1955 y 2015-2040 para todo el país. Los datos obtenidos permitieron construir probables escenarios pasados y futuros de la fecundidad por edad y se revelaron relativamente coherentescon la información y las tendencias sociodemográficas generales, lo que permitióreabrir preguntas acerca del proceso de transición de la fecundidad.The goal of this article is to model and project fertility rates by age in Argentina, using vital statistics (1980-2014), population estimates, censuses, and previous estimates of fertility rates by age available for the 1955-1980 period. Using functional series models, we estimate fertility rates by age for the 1895-1950 and 2015- 2040 periods, at the national level. The data obtained allowed the construction of probable past and future age-specific fertility scenarios and revealed a relative consistency with generalFil: Sacco Zeballos, Nicolás.

Regional variation in suicide rates in Sri Lanka between 1955 and 2011:a spatial and temporal analysis

Abstract Background Between 1955 and 2011 there were marked fluctuations in suicide rates in Sri Lanka; incidence increased six-fold between 1955 and the 1980s, and halved in the early 21st century. Changes in access to highly toxic pesticides are thought to have influenced this pattern. This study investigates variation in suicide rates across Sri Lanka’s 25 districts between 1955 and 2011. We hypothesised that changes in the incidence of suicide would be most marked in rural areas due to the variation in availability of highly toxic pesticides in these locations during this time period. Methods We mapped district-level suicide rates in 1955, 1972, 1980 and 2011. These periods preceded, included and postdated the rapid rise in Sri Lanka’s suicide rates. We investigated the associations between district-level variations in suicide rates and census-derived measures of rurality (population density), unemployment, migration and ethnicity using Spearman’s rank correlation and negative binomial models. Results The rise and fall in suicide rates was concentrated in more rural areas. In 1980, when suicide rates were at their highest, population density was inversely associated with area variation in suicide rates (r = −0.65; p < 0.001), i.e. incidence was highest in rural areas. In contrast the association was weakest in 1950, prior to the rise in pesticide suicides (r = −0.10; p = 0.697). There was no strong evidence that levels of migration or ethnicity were associated with area variations in suicide rates. The relative rates of suicide in the most rural compared to the most urban districts before (1955), during (1980) and after (2011) the rise in highly toxic pesticide availability were 1.1 (95% CI 0.5 to 2.4), 3.7 (2.0 to 6.9) and 2.1 (1.6 to 2.7) respectively. Conclusions The findings provide some support for the hypothesis that changes in access to pesticides contributed to the marked fluctuations in Sri Lanka’s suicide rate, but the impact of other factors cannot be ruled out

Why Have Girls Gone to College? A Quantitative Examination of the Female College Enrollment Rate in the United States: 1955-1980

This paper documents a dramatic increase in the college enrollment rate of women from 1955 to 1980 and asks a quantitative question: to what extent can such increase be accounted for by the change in the female cohort-specific college wage premium? I develop and calibrate an overlapping generations model with discrete schooling choice. I find that changes in the life-cycle earnings differential can explain the increase in the female college enrollment rate very well. Young women's changing expectations of future earnings may also play an important role in driving their college attendance decision.Female College Enrollment rate, College Wage Premium, Life-cycle

Bibliography on aerodynamics of airframe/engine integration of high-speed turbine-powered aircraft, volume 1

This bibliography was developed as a first step in the preparation of a monograph on the subject of the aerodynamics of airframe/engine integration of high speed turbine powered aircraft. It lists 1535 unclassified documents published mainly in the period from 1955 to 1980. Primary emphasis was devoted to aerodynamic problems and interferences encountered in the integration process; however, extensive coverage also was given to the characteristics and problems of the isolated propulsion system elements. A detailed topic breakdown structure is used. The primary contents of the individual documents are indicated by the combination of the document's title and its location within the framework of the bibliography
