Does Livestock Ownership Affect Animal Source Foods Consumption and Child Nutritional Status? Evidence from Rural Uganda

Abstract

In many developing countries consumption of animal source foods (ASF) among the poor is still at a level where increasing its share in total caloric intake may have many positive nutritional benefits. This paper explores whether ownership of different livestock species increases consumption of ASF and helps improving child nutritional status, finding some evidence that both food consumption patterns and nutritional outcomes may be affected by livestock ownership in rural Uganda. Our results are suggestive that promoting (small) livestock ownership has the potential for affecting human nutrition in rural Uganda, but further research is needed to more precisely estimate the direction and size of these effects.     

Presidential Approval and Public Security in Mexico's War on Crime

To fight criminal organizations effectively, governments require support from significant segments of society. Citizen support provides important leverage for executives, allowing them to continue their policies. Yet winning citizens' hearts and minds is not easy. Public security is a deeply complex issue. Responsibility is shared among different levels of government; information is highly mediated by mass media and individual acquaintances; and security has a strong effect on peoples' emotions, since it threatens to affect their most valuable assets—life and property. How do citizens translate their assessments of public security into presidential approval? To answer this question, this study develops explicit theoretical insights into the conditions under which different dimensions of public security affect presidential approval. The arguments are tested using Mexico as a case study.     

In Search of Paradise

<正>When winter rolls over northern China and endless days of smog have you wandering around in a comatose state,there is only one remedy—and it doesn’t come in a bottle.It’s sunshine,blue skies,and beaches.I conducted a survey amongst my friends regarding the best place to catch some waves and the same location kept coming up.     

Spillover Effects: Immigrant Policing and Government Skepticism in Matters of Health for Latinos

To what extent do people become less trusting of the government under threatening policy contexts? The authors find evidence that Secure Communities, a bureaucratic program that enhances immigrant policing through collaboration between local law and immigration enforcement agencies, spurs mistrust among Latinos but not non‐Latinos. This article focuses on the politics of immigration and health, two issue areas marked by large‐scale bureaucratic developments over the last 50 years. The authors argue that a major consequence of expanding immigrant policing is its trickle‐down effect on how individuals view public institutions charged with the provision of public goods, such as health information. The results indicate that Latinos in locales where immigrant policing is most intense express lower levels of trust in government as a source of health information. Through a policy feedback lens, the findings suggest that the state's deployment of immigrant policing conveys more widespread lessons about the trustworthiness of government .     

Analysis of Delta9-tetrahydrocannabinol in oral fluid samples using solid-phase extraction and high-performance liquid chromatography-electrospray ionization mass spectrometry

An analytical method using solid-phase extraction (SPE) and high-performance liquid chromatography-mass spectrometry (LC-MS) has been developed and validated for the confirmation of Delta(9)-tetrahydrocannabinol (THC) in oral fluid samples. Oral fluid was extracted using Bond Elut LRC-Certify solid-phase extraction columns (10 cm(3), 300 mg) and elution performed with n-hexane/ethyl acetate. Quantitation made use of the selected ion-recording mode (SIR) using the most abundant characteristic ion [THC+H(+)], m/z 315.31 and the fragment ion, m/z 193.13 for confirmation, and m/z 318.00 for the protonated internal standard, [d(3)-THC+H(+)]. The method proved to be precise for THC, in terms of both intra-day and inter-day analyses, with coefficients of variation less than 10%, and the calculated extraction efficiencies for THC ranged from 76 to 83%. Calibration standards spiked with THC between 2 and 100 ng/mL showed a linear relationship (r(2)=0.999). The method presented was applied to the oral fluid samples taken from the volunteers during the largest music event in Portugal, named Rock in Rio-Lisboa. Oral fluid was collected from 40 persons by expectoration and with Salivette. In 55% of the samples obtained by expectorating, THC was detected with concentration ranges from 1033 to 6552 ng/mL and in 45% of cases THC was detected at concentrations between 51 and 937 ng/mL. However, using Salivette collection, 26 of the 40 cases had an undetectable THC.     

Allele frequencies and haplotypes of 8 Y-chromosomal STRs in the Santa Catarina population of southern Brazil

Allele frequencies and haplotypes of eight Y-chromosomal short tandem repeats (STRs), DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393 were determined in a sample of 109 males from Santa Catarina. The origin of this southern Brazilian population is mainly from Portuguese people, namely from Azores archipelago.
