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.     

Won't you be my neighbor? Using an ecological approach to examine the impact of community on revictimization

An ecological model is used to explore the moderating effects of community-level variables on the relation between childhood sexual, physical, and emotional abuse and adult intimate partner violence (IPV) within a sample of 98 African American women from low incomes. Results from hierarchical, binary logistics regressions analyses show that community-level variables (perceived neighborhood disorder and community cohesion) moderated the relation between childhood emotional abuse and adult physical IPV. Findings support the use of an ecological approach in examining the phenomena of revictimization. Clinical implications from a community and ecological perspective are discussed.     

Governance landscapes for emerging technologies: The case of cryptocurrencies

Scholars call for “adaptive governance” to balance concern about technology uncertainty with the need for innovation in the governance of emerging technologies. Yet, empirical assessment of such governance systems remains sparse. Do the actors interested in the potential regulation of an emerging technology focus on their own interests and opportunities, or do they think in terms of the collective interest? We focus on the actors who embed such systems from a novel landscape perspective that combines two dimensions of governance: the nature of the regulatory target, and the nature of the process they advocate for governing the target. We present data from over 70 actors in the area of cryptocurrencies for evaluating this new logic.
