What Makes People Infidel? An Analysis of the Influence of Demographics on Extramarital Affairs
People in most cultures view sexual fidelity as one of the key foundations of a strong marital relationship. When a person engages in extramarital affairs, irrespective of the length of involvement in such an activity and whether or not the spouse is aware of it, the mutual \u27trust\u27 in \u27sexual fidelity\u27 takes an intrinsic blow. This paper explores the causes behind extramarital affairs from an economic perspective by statistically testing the hypothesis that the numbers of extramarital affairs people have depend on demographic characteristics of the population
Civic Engagement in Low Income and Minority Neighborhoods, and the Role of Public Investment
This study uses principal component analysis to measure civic engagement in the low-income and minority neighborhood of Fair Park in South Dallas, and seeks to identify the implications of the influx of public investment in the Fair Park neighborhood on civic engagement

Counties with More Vietnam Veterans Have Higher Suicide Rates
Despite a deep concern from policymakers and the public alike, detailed records linking military service records and suicide do not exist on a national scale. Here, we determine how suicide rates are related to the veteran population by linking data from the Centers for Disease Control (CDC) at the county-level with estimates of veteran populations by service period from the American Community Survey. While this is an indirect approach, this panel analysis allows us to uncover a robust and persistent finding: counties with larger Vietnam veteran populations have higher suicide rates. Our modeling strategy includes standard panel data methodology, sub-state analysis based on the adoption of Child Access Prevention laws governing firearms, and a recent innovation in instrumental variables methodology coupled with county birth records from lottery years as an instrument. Ultimately, we find that a standard deviation increase in the Vietnam veteran population is associated with 1.9 to 6 additional suicides per 100,000 people

Nanocrystalline Gadolinium Doped Ceria: Combustion Synthesis and Electrical Characterization
Twenty mol% gadolinium doped ceria powders were prepared by citrate-nitrate combustion synthesis technique. Two different sources of cerium viz. cerium nitrate and ammonium ceric nitrate were used in different oxidant-to-fuel ratios. The crystallite size of the synthesized powders ranged 5-27 nm was obtained depending on the preparation conditions with average particle size in the range 0.64-1.26 mu m. Although, the powders were found to be agglomerated in nature, these powders were highly sinter-active as they showed very high sintered density (>= 95%) when sintered at 1250 degrees C having grain size in the range of 200-500 nm. The electrical conductivity was found to depend on the temperature with two distinct regimes at a transition point of 350 degrees C. The grain boundary showed a significant role in the total conductivity with its activation energy dependent on the material preparation conditions. The activation energy of total conduction was found to be significantly low (similar to 0.5 eV) in the temperature range of 400-700 degrees C, this property is unique for application as an electrolyte for solid oxide fuel cell operating in the low temperature range. It was found that a fuel-deficient combustion reaction using cerium nitrate as the oxidant yielded the best quality powder which showed a maximum electrical conductivity of similar to 1.74 x 10(-2) S/cm at 600 degrees C
Ionic conductivity studies on neodymium doped ceria in different atmospheres
Nano-crystalline 10 and 20 mol% neodymium (Nd) doped ceria powders were prepared by gel-combustion synthesis. The single-phase nature of the nano powder has been confirmed by X-ray diffraction. These sinter-active nano powders resulted in dense products, as the sintered densities were found to be similar to 90% of theoretical densities. Ionic conductivity studies were carried out in air, hydrogen and oxygen atmospheres. The samples showed ionic conductivity of 1.3 x 10(-2) cm(-1) at 650 degrees C, and the activation energy values obtained in this system were in the range of 0.7-1.0 eV. These studies also revealed that no electronic conduction was observed, as the ionic conductivity values were almost similar in different environments
