Location Efficiency and Mortgage Risks for Low-Income Households

Abstract

Household energy expenditures, especially for transportation, are fairly inelastic. Their effects on low-income households may be significant, due to the potential for energy consumption to displace other types of consumption when energy prices rise. Using accessibility as a proxy for lower transportation costs, we test the hypothesis that low- and moderate-income residents are less likely default when they are located in more accessible places. We find that regional accessibility has almost no effect on risks of default, but local job diversity has moderate mitigating effect.     

Use of Embryos Extracted from Individual Cannabis sativa Seeds for Genetic Studies and Forensic Applications

Legal limits on the psychoactive tetrahydrocannabinol (THC) content in Cannabis sativa plants have complicated genetic and forensic studies in this species. However, Cannabis seeds present very low THC levels. We developed a method for embryo extraction from seeds and an improved protocol for DNA extraction and tested this method in four hemp and six marijuana varieties. This embryo extraction method enabled the recovery of diploid embryos from individual seeds. An improved DNA extraction protocol (CTAB3) was used to obtain DNA from individual embryos at a concentration and quality similar to DNA extracted from leaves. DNA extracted from embryos was used for SSR molecular characterization in individuals from the 10 varieties. A unique molecular profile for each individual was obtained, and a clear differentiation between hemp and marijuana varieties was observed. The combined embryo extraction–DNA extraction methodology and the new highly polymorphic SSR markers facilitate genetic and forensic studies in Cannabis.     

Forensic databases,a perspective from the penitentiary centers of Spain

Scientific and technological progress in the field of forensic genetics is very useful in the resolution of criminal cases, but it entails the need for a deep ethical reflection, as the individual Fundamental Rights may be violated.This project aims to collect and compare the opinion of prisoners and prison officials on what characteristics the country's forensic database should have. In this context, 210 subjects were surveyed, 101 of them prisoners and the rest prison officials, from three different Spanish penitentiary centers.Among the results obtained, most prisoners and officials consider the national DNA database to be useful, and additionally, a 40% of the participants would support the integration of the profiles of the entire population. 64% considered it ethical to use the DNA profiles of the database as a tool for familial searching. Despite this, half of the respondents are concerned about the future uses of the DNA database.Integrating the opinion of these analyzed groups with other relevant judicial, scientific and ethical convictions, ensures the regulation between security and individual’s Human Rights.
