The Brazilian agro-industrial frontier in Mato Grosso rapidly expanded in total area of mechanized production and in total value of production in the last decade. This article shows the spatial pattern of that expansion from 2000 to 2010, based on novel analyses of satellite imagery. It then explores quantitatively and qualitatively the antecedents and correlates of intensification, the expansion of the area under two crops per year. Double cropping is most likely in areas with access to transportation networks, previous profitable agricultural production, and strong existing ties to national and international commodity markets. The article concludes with an exploration of the relationship between double cropping and socioeconomic development, showing that double cropping is strongly correlated with incomes of all residents of a community and with investments in education. We conclude that double cropping in Mato Grosso is very closely tied to multiple indicators of socioeconomic development.

SummaryCross-regional correlations between average IQ and socioeconomic development have been documented in many different countries. This paper presents new IQ estimates for the twelve regions of the UK. These are weakly correlated (r=0.24) with the regional IQs assembled by Lynn (1979). Assuming the two sets of estimates are accurate and comparable, this finding suggests that the relative IQs of different UK regions have changed since the 1950s, most likely due to differentials in the magnitude of the Flynn effect, the selectivity of external migration, the selectivity of internal migration or the strength of the relationship between IQ and fertility. The paper provides evidence for the validity of the regional IQs by showing that IQ estimates for UK nations (England, Scotland, Wales and Northern Ireland) derived from the same data are strongly correlated with national PISA scores (r=0.99). It finds that regional IQ is positively related to income, longevity and technological accomplishment; and is negatively related to poverty, deprivation and unemployment. A general factor of socioeconomic development is correlated with regional IQ atr=0.72.

The Relationship

The article discusses a non-standard view of the formation of human capital for work in organizations of the agricultural sector of the economy, in the context of modern socio-economic transformations. In the classical sense, human capital for agriculture should be formed and developed in rural areas. But in real life, this is not always the case, because there are many factors that prevent the classical solution of this problem. First, the demographic factor affects, second, social and household factors, and third, in many rural areas there are no working agricultural organizations where qualified agricultural specialists can work. All these and other circumstances actualize the problem of the quality of human capital in rural areas in relation to the development of agricultural production.

The Relationship

The author begins by discussing the relationship between agriculture and population at a theoretical level, proceeds with a historical review of changes in the role and significance of an individual as agricultural producer, and finally, analyzes population as an element (potentials - limitations) of agricultural development in Serbia. The overall production results, and particularly the propensity to technical and technological innovation, as well as the ability to adapt to the changed conditions are, as we know well, crucially dependent on the structure of the working population. Hence, the author discusses regional differences in agricultural population by age, sex, level of education and productivity to provide a clear illustration of the impact of this element (indicator) on the population as the factor of agricultural production. The results show significant macroregional differences by this element with respect to the average for Serbia.

Small- and medium-sized family farms are places to live and sources of income for about half of the population. The aim of this analysis was to determine the relationship between eco-efficiency and human capital efficiency on small- and medium-sized family farms. The analysis was carried out using an economic measure (value of agricultural production per work hour calculated per hectare) and two synthetic measures (human capital and environmental measures). The synthetic measures were determined using the TOPSIS-CRITIC method by defining weights for variables used in the measures. The analysis covered five countries: Lithuania (960 farms), Moldavia (532 farms), Poland (696 farms), Romania (872 farms) and Serbia (524 farms). All of these countries are characterised by a high fragmentation of agricultural holdings. The analysis allowed us to formulate the following conclusions: eco-efficiency and human capital efficiency indices increased with area for small- and medium-sized family farms. An increase in the eco-efficiency index with an increase in farm area suggests that the smaller the farm area, the more extensive the agricultural production that was carried out. In addition, an increase in human capital efficiency with an increase in farm area indicates that there was inefficiency in the utilisation of human capital resources on the agricultural farms studied.

AbstractThis paper investigates gender differences in university performances in Science, Technology, Engineering and Mathematics (STEM) courses in Italy, proposing a novel application through the segmented regression models. The analysis concerns freshmen students enrolled at a 3-year STEM degree in Italian universities in the last decade, with a focus on the relationship between the number of university credits earned during the first year (a good predictor of the regularity of the career) and the probability of getting the bachelor degree within 4 years. Data is provided by the Italian Ministry of University and Research (MIUR). Our analysis confirms that first-year performance is strongly correlated to obtaining a degree within 4 years. Furthermore, our findings show that gender differences vary among STEM courses, in accordance with the care-oriented and technical-oriented dichotomy. Males outperform females in mathematics, physics, chemistry and computer science, while females are slightly better than males in biology. In engineering, female performance seems to follow the male stream. Finally, accounting for other important covariates regarding students, we point out the importance of high school background and students’ demographic characteristics.

Abstract Precise mechanisms underlying sperm storage and utilization are largely unknown, and data directly linking stored sperm to paternity remain scarce. We used competitive microsatellite PCR to study the effects of female morphology, copula duration and oviposition on the proportion of stored sperm provided by the second of two copulating males (S2) in Scathophaga stercoraria (Diptera: Scathophagidae), the classic model for sperm competition studies. We genotyped all offspring from potentially mixed-paternity clutches to establish the relationship between a second male’s stored sperm (S2) and paternity success (P2). We found consistent skew in sperm storage across the three female spermathecae, with relatively more second-male sperm stored in the singlet spermatheca than in the doublet spermathecae. S2 generally decreased with increasing spermathecal size, consistent with either heightened first-male storage in larger spermathecae, or less efficient sperm displacement in them. Additionally, copula duration and several two-way interactions influenced S2, highlighting the complexity of postcopulatory processes and sperm storage. Importantly, S2 and P2 were strongly correlated. Manipulation of the timing of oviposition strongly influenced observed sperm-storage patterns, with higher S2 when females laid no eggs before being sacrificed than when they oviposited between copulations, an observation consistent with adaptive plasticity in insemination. Our results identified multiple factors influencing sperm storage, nevertheless suggesting that the proportion of stored sperm is strongly linked to paternity (i.e., a fair raffle). Even more detailed data in this vein are needed to evaluate the general importance of sperm competition relative to cryptic female choice in postcopulatory sexual selection.

- Country life is (and has been) the object of utopian visions, set against the rise of urban living. The paradigms of the myth of rural life can be traced back to Howard's Garden City and to Frank Lloyd Wright's Broadacre City. These examples of the paradigm blend into a broader and trans-disciplinary contemporary discourse on the myth of rural living. Since the end of the 1990s, the subject of the relationship between the rural and the urban has developed into plans that could be called ‘country utopias'. The system of agricultural production and the countryside is evolving today towards new forms of integration and hybridisation with urban areas. Planning practices are emerging today in the definition of the characters and traits of urban agriculture designed to create town and country interaction particularly in marginal areas, strips located on the borders between town and country. These modifications are leading to the definition of new rural figures, together with plans capable of giving new life to liminal and marginal areas between town and country by creating new models of ‘rururban' living.

Mato Grosso

La production de soja a augmenté de manière considérable les dix dernières années au Mato Grosso, atteignant 17,9millions de tonnes en 2009 (contre 7,2 en 1998). Une telle expansion a eu de graves conséquences environnementales et socio-économiques, telles que la déforestation et l'urbanisation. L'objectif de cet article est de mettre en avant l'efficacité des techniques de télédétection et des indices qui en découlent, tels que le NDVI, pour analyser l'avancée des champs de soja au Mato Grosso ainsi que la transformation de l'agriculture dans cetÉtat. L'indice NDVI a été calculé à partir de séries mensuelles du capteur SPOT-Vegetation. Il a permis de trouver les zones cultivées et de surveiller la croissance des cultures. Il a aussi permis la détection des pratiques de gestion de double culture, qui se sont drastiquement accrues depuis quelques années. Les résultats ont montré une corrélation de 0,98 entre notre estimation des zones cultivées et les statistiques agricoles officielles de l'IBGE pour l'intégralité du Mato Grosso. Les séries temporelles de NDVI ont également confirmé l'augmentation des systèmes de double culture, représentant 30% des zones cultivées en 1999, 57% en 2006 et 67% en 2009. Cette évolution est un indicateur de la diversification de l'agriculture et de l'intensification des traitements dans cette région. En outre, la surveillance des grandes clairières récentes au niveau local (comté de Vera) a montré une réduction de l'écart entre trois états consécutifs conduisant à l'intensification des pratiques agricoles. En se fondant sur notre méthodologie, nous avons finalement proposé une classification des municipalités selon leurs modes d'usages du sol dominants.

The Pantanal hydrological cycle holds an important meaning in the Alto Paraguay Basin, comprising two areas with considerably diverse conditions regarding natural and water resources: the Plateau and the Plains. From the perspective of the ecosystem function, the hydrological flow in the relationship between plateau and plains is important for the creation of reproductive and feeding niches for the regional biodiversity. In general, river declivity in the plateau is 0.6 m/km while declivity on the plains varies from 0.1 to 0.3 m/km. The environment in the plains is characteristically seasonal and is home to an exuberant and abundant diversity of species, including some animals threatened with extinction. When the flat surface meets the plains there is a diminished water flow on the riverbeds and, during the rainy season the rivers overflow their banks, flooding the lowlands. Average annual precipitation in the Basin is 1,396 mm, ranging from 800 mm to 1,600 mm, and the heaviest rainfall occurs in the plateau region. The low drainage capacity of the rivers and lakes that shape the Pantanal, coupled with the climate in the region, produce very high evaporation: approximately 60% of all the waters coming from the plateau are lost through evaporation. The Alto Paraguay Basin, including the Pantanal, while boasting an abundant availability of water resources, also has some spots with water scarcity in some sub-basins, at different times of the year. Climate conditions alone are not enough to explain the differences observed in the Paraguay River regime and some of its tributaries. The complexity of the hydrologic regime of the Paraguay River is due to the low declivity of the lands that comprise the Mato Grosso plains and plateau (50 to 30 cm/km from east to west and 3 to 1.5 cm/km from north to south) as well as the area's dimension, which remains periodically flooded with a large volume of water.
