Trends in Mortality of the Soviet Population

Two prominent American demographers present an up-to-date study of trends and countertrends in mortality of the Soviet population; discussed are variations (by republic and over time) in life expectancy, infant mortality, and mortality in the working ages. Analyzing trends since 1959, the authors highlight problems relating to the quality and interpretation of pertinent statistical data of Soviet origin. Distinguishing real trends from pseudotrends, they evaluate mortality differences among regions and illustrate a more favorable long-term trend in mortality than suggested by official figures (nonetheless, because of error in official statistics, actual rates are generally higher).

Potentials for federation of East African educational programmes

Educational planning, in the modern sense of the term, goes back in Thailand no further than 1962, when the Second Economic and Social Development Plan (1962/66) was launched. The Second Plan included a plan for the educational system as did the Third Plan (1967/71) which is now drawing to a close. These two educational plans were based on a variety of methods, including those of making long‐term forecasts of manpower requirements. Between 1963 and 1967, five different groups prepared manpower forecasts for Thailand, some of which looked no further than 1970, while others projected manpower requirements up to 1968. In this paper we will try to assess the quality of these forecasts and, so far as it is possible, to cmmpare prediction with outcome.

The paper consists of four parts. We begin with a brief review of background data in order to highlight the problems of manpower forecasting in an economy such as that of Thailand. The second section is devoted to a detailed discussion of the first and most ambitious of the five forecasts that have been made in Thailand. This is followed by brief evaluations of the remaining four forecasts. In the fast section, we will consider the influence that these forecasts actually exerted on educational planning in Thailand.     

Factors influencing the precision of estimating the postmortem interval using the triple-exponential formulae (TEF). Part I. A study of the effect of body variables and covering of the torso on the postmortem brain, liver and rectal cooling rates in 117 forensic cases

Brain, liver, rectal and environmental temperatures were continuously monitored under controlled conditions, in 117 forensic fatalities, for up to 60 h after death. Cases were studied either naked (63%) or covered with two blankets (37%). Bodies were classified into fat and thin groups. Statistical analysis and curve-fitting of the data yielded the average triple-exponential formulae for each body site and each body group. The effects of covering of the torso and body parameters such as weight, height, surface area and 'cooling size factor' (Z) on postmortem cooling are assessed and discussed. Results show that covering of the torso has a significant influence on the rate of postmortem cooling, however, there is no good correlation between the body variables and the cooling rate.     

Factors influencing the precision of estimating the postmortem interval using the triple-exponential formulae (TEF). Part II. A study of the effect of body temperature at the moment of death on the postmortem brain, liver and rectal cooling in 117 forensic cases

The temperatures of three body sites, namely, the brain, liver and the rectum as well as the temperature of the environment were continuously monitored, every 5-10 min, in 117 forensic cases commencing soon after death and in most cases, within 45 min postmortem. The body temperature at the moment of death was empirically determined by a computer-based extrapolation method. Thus, temperature data for the first 3h of each body site were fitted to single-exponential equations and the fitted curve was extrapolated backwards to obtain the intercept on the Y-axis (the temperature axis). The effect of body temperature at the moment of death on postmortem cooling rate is examined and factors influencing body temperature at death are discussed. Forensic fatalities associated with hyper and hypothermia are reviewed briefly.     

Variation is the Norm: A Landscape Analysis of Weighted Student Funding Implementation

School districts increasingly rely on weighted student funding (WSF), yet there is little research on this allocation model. This study collects more than 70 measures on each of 19 districts using WSF in 2018 for a landscape analysis of formula features and implementation practices. While districts report common reasons for adopting WSF (equity, flexibility, and transparency), we find no standard WSF model. Homegrown formulas and nonformula features and exemptions reflecting local context are the norms, resulting in substantial differences. Nearly all districts continue to budget with average salaries (likely limiting equity) but grant principals flexibility on staffing, stipends, and contracts.
