The geopolitics of Brazilian soybeans

Soybean plays a major role in the development of Brazilian agribusiness, and in turn in Brazilian geopolitical power as well. It is a pillar of Brazil's insertion into a ‘new multi-polar world order’ as basis for much Brazilian land ownership in neighboring countries, for the extension of political influence in Africa, and it is especially important for balancing trade with Brazil's new primary commercial partner, China. Yet the US dollar and North Atlantic transnational companies still control global soybean markets and production technologies. In a context marked by booming but volatile commodity prices, food crises, riots and revolutions in food-importing countries, a global rush for farmland, and severe droughts and climate change, the soybean agribusiness in Brazil takes on new and crucial geopolitical significance. I trace the geopolitical role it has served in consolidating the ‘green revolution’ in Brazil, and raise questions about the intersection between agroindustrial markets and currencies: could agricultural commodities serve geopolitical functions (and thus contestation) similar to those ‘petro-dollars’ have served since the 1970s? These considerations show how the political ecology of soybean shapes and is shaped by inter-regional and global-scale processes, and reveals new directions for research on the emerging geopolitical landscape of our century.     

Constructing Institutional Measures: Indicators of Political and Property Rights in Mozambique, 1900–2005

In this article, we focus on the role of political and economic institutions in Mozambique's development. We produce a set of institutional indicators for Mozambique for the period 1900–2005. The first index tracks political freedoms and is unique in its duration and complexity. The second index is a measure of property rights for Mozambique, and such a measure has not existed previously and certainly not for this length of time. The construction of these indices is a painstaking process through historical records but it provides us with a richness of institutional data previously not available. The new institutional indices will allow us to explore the role of the institutional environment in determining economic growth and development in Mozambique over time.     

Heteroplasmy in hair: differences among hair and blood from the same individuals are still a matter of debate

The analysis of mitochondrial DNA (mtDNA) is a useful tool in forensic cases when sample contents too little or degraded nuclear DNA to genotype by autosomal short tandem repeat (STR) loci, but it is especially useful when the only forensic evidence is a hair shaft. Several authors have related differences in mtDNA from different tissues within the same individual, with high frequency of heteroplasmic variants in hair, as also in some other tissues. Is still a matter of debate how the differences influence the interpretation forensic protocols. One difference between two samples supposed to be originated from the same individual are related to an inconclusive result, but depending on the tissue and the position of the difference it should have a different interpretation, based on mutation-rate heterogeneity of mtDNA. In order to investigate it differences in the mtDNA control region from hair shafts and blood in our population, sequences from the hypervariable regions 1 and 2 (HV1 and HV2) from 100 Brazilian unrelated individuals were compared. The frequency of point heteroplasmy observed in hair was 10.5% by sequencing. Our study confirms the results related by other authors that concluded that small differences within tissues should be interpreted with caution especially when analyzing hair samples.     

Amphetamine, cocaine and cannabinoids use among truck drivers on the roads in the State of Sao Paulo, Brazil

Lysergic acid diethylamide (LSD) is a potent hallucinogen, active at very low dosage and its determination in body fluids in a forensic context may present some difficulties, even more so in hair. A dedicated liquid chromatography-electrospray-tandem mass spectrometry (LC-ES-MS/MS) assay in hair was used to document the case of a 24-year-old man found dead after a party. Briefly, after a decontamination step, a 50mg sample of the victim's pubic hair was cut into small pieces (<1mm length), and incubated overnight in 3mL of phosphate buffer pH 5 at room temperature. After a liquid-liquid extraction (dichloromethane/ether), the extract was analyzed using a LC-ES-MS/MS method exhibiting a limit of quantification of 0.5pg/mg for LSD. A LSD concentration of 0.66pg/mg of pubic hair was observed. However, this result remains difficult to interpret owing to the concomitant LSD presence in the victim's post mortem blood and urine, the lack of previously reported LSD concentrations in hair, and the absence of data about LSD incorporation and stability in pubic hair.     

Estimation of age at death from the pubic symphysis and the auricular surface of the ilium using a smoothing procedure

We discuss here the estimation of age at death from two indicators (pubic symphysis and the sacro-pelvic surface of the ilium) based on four different osteological series from Portugal, Great-Britain, South Africa or USA (European origin). These samples and the scoring system of the two indicators were used by Schmitt et al. (2002), applying the methodology proposed by Lucy et al. (1996). In the present work, the same data was processed using a modification of the empirical method proposed by Lucy et al. (2002). The various probability distributions are estimated from training data by using kernel density procedures and Jackknife methodology. Bayes's theorem is then used to produce the posterior distribution from which point and interval estimates may be made. This statistical approach reduces the bias of the estimates to less than 70% of what was obtained by the initial method. This reduction going up to 52% if knowledge of sex of the individual is available, and produces an age for all the individuals that improves age at death assessment.     

The Impact of Private Precautions on Home Burglary and Robbery in Brazil

Objectives

This study evaluates the effects of precaution technologies (i.e., window bars, extra locks, alarms and electric fences, CCTV, private security, dogs and combinations of these tools) on household burglary and robbery in Brazil.

Methods

Using a sample of 121,042 unique households from the Brazilian National Household Sample Survey for 2009, this study estimates a Recursive Bivariate Probit to obtain the average treatment effect of these precaution technologies in the likelihood of home burglary and robbery victimization.

Results

This study demonstrates that technology does not reduce home burglaries, but certain combinations of technologies may reduce home robberies. The combination of electric fences and alarms with private security reduces the likelihood of home robbery by 9.5 %, and when combined with a dog, these technologies reduce the likelihood of home robbery by 86 %.

Conclusions

No precaution technology is able to prevent crimes when employed independently. Occupancy combined with a set of technologies can reduce the expected victimization in crimes against property.

     

Nondecision making and inertia in Portuguese health policy

Despite there having been a positive context for initiating health care reforms in Portugal in the past fifteen years (accompanied by political consensus on the nature of the structural problems within the health care system), there has been a lack of reform initiatives. We use a process-based framework to show how institutional arrangements have influenced Portuguese health care reform. Evidence is presented to demonstrate inertia and nondecision making in three critical areas of Portuguese health policy: clarifying the public-private mix in coverage and provision, creating financial incentives and motivation for human resources, and introducing changes in the pharmaceutical market. Several factors seem to explain these processes, namely, problems in the balance of power within the political system, which have contributed to a lack of proper policy discussion; a lack of pluralism in the formation of health care policies (with low participation from citizens and high mobilization among structural interest groups); and the low priority of health care in public sector reforms. Portuguese politicians should be aware of the pitfalls of the current political system that constrain participatory arrangements and pluralism in policy making. In order to pursue health care reform, future governments will need to counterbalance the strong influence of structural interest groups.     

The participation of women in urban labor markets in Mexico: 1970-1980

This article analyzes the presence of women in urban labor markets in Mexico during the 1970s in terms of the regional location of the city and the type and diversity of employment opportunities for women. 49 cities with over 100,000 inhabitants in 1980 were grouped into 3 regions, the relatively urban and industrial north, the heterogeneous center, and the less developed south. Census data for 1970 and 1980 on male and female labor force participation in the municipios containing the 49 cities were analyzed to assess urban labor markets. The cities were grouped according to whether they had higher or lower than average rates of labor force participation in the 2 study years. The cities of the north included the greatest relative number of cases of low female and male labor force participation in 1970 and 1980 and a declining trend for the 1970s. Cities of the center had the highest levels of male and female labor force participation in both 1970 and 1980 and showed a trend toward increasing female participation in the 1970s. Cities in the south were in an intermediate position, but during the 1970s a high percentage showed a trend toward increase in male participation and decrease in female participation. Typologies of the cities were then constructed based on female age specific participation rates and female occupational distribution. Urban areas with high rates of participation among young women aged 15-24 years were distinguished from those with high participation rates for younger and older women, and those with less diversified employment opportunities for women were distinguished from those with more diversity. Female participation presented marked variations between regions. In general, women participated to a greater degree in diversified labor markets that absorbed workers of different ages and degrees of qualification. There were not necessarily more female workers in cities that were more dynamic in terms of economy and male participation. Cities of 100,000 or more inhabitants in the center were characterized by a high proportion of women of different ages in the labor market. Cities in the north had lower average levels of female participation although those on the northern border had a high participation of young women in manufactures and assembly. Southern cities employed women in manual occupations, especially in commerce and services. Primarily adolescents under 15 and women over 25 were employed. Apart from the regional variations there were variations in female employment within regions. An annex discusses the study methodology in greater detail.
