Using Rural Household Income Survey Data to Inform Poverty Analysis: An Example from Mozambique

This paper demonstrates that income survey data can be very informative in explaining the variation across households in the incidence and severity of absolute poverty using a rural household income data set for Mozambique. Results from regression analysis of the sources of variation are used to simulate the impact of alternative agricultural interventions or strategies on rural poverty. Complementarities in the insights gained from consumption expenditure and income surveys may justify the collection and analysis of both types of information, especially in Sub-Saharan Africa, the one region of the world where the incidence of poverty is increasing.Poverty analysis, household income surveys, agricultural development, Millenium Development Goals, Mozambique, Consumer/Household Economics, Food Security and Poverty, C21, I3, O13, O2, Q18,

Geography of AirBnb in Barcelona and Lisbon: A comparative study

Over the last decade, Airbnb has emerged as the most important actor in the short-term rental business worldwide. The spatial distribution of Airbnb accommodations in a city is highly sensitive to the location of different spatial, socioeconomic, demographic, and cultural factors, and therefore has the potential to increase existing and create spatial inequalities in host cities. Drawing from the data from the Inside Airbnb website, the 2011 census of population and housing, the municipal registers, and Open Street Maps, this article first measures and analyses the degree of penetration and spatial clustering (with LISA statistics) of Airbnb listings in Barcelona and Lisbon. Then, it explores the spatial, socioeconomic, demographic, and cultural determinants of the spatial clustering of accommodations offered on Airbnb in both cities. Finally, it examines the impact of the COVID-19 pandemic on the spread of Airbnb in both cities. Results show that Airbnb has penetrated deeply into the central residential areas and around major tourist attractions, and it is deepening spatial inequalities by benefitting mainly the upper income group of homeowners in these neighbourhoods. Lastly, the recent COVID-19 pandemics has curtailed the spread and changed the typology of accommodation offered on Airbnb.info:eu-repo/semantics/publishedVersio

Using Machine Learning techniques in phenomenological studies on flavour physics

An updated analysis of New Physics violating Lepton Flavour Universality, by using the Standard Model Effective Field Lagrangian with semileptonic dimension six operators at ¿ = 1 TeV is presented. We perform a global fit, by discussing the relevance of the mixing in the first generation. We use for the first time in this context a Montecarlo analysis to extract the confidence intervals and correlations between observables. Our results show that machine learning, made jointly with the SHAP values, constitute a suitable strategy to use in this kind of analysis

Leptonic meson decays into invisible ALP

The theoretical calculation of pseudo–scalar leptonic decay widths into an invisible ALP, M→ℓνℓa, is reviewed. Assuming generic flavor–conserving ALP couplings to SM fermions and a generic ALP mass, ma, the latest experimental results for pseudo–scalar leptonic decays are used to provide updated bounds on the ALP–fermion Lagrangian sector. Constrains on the ALP-quark couplings obtained from these channels are not yet competitive with the ones derived from FCNC processes, like M→Pa decays. These leptonic decays can, however, provide the most stringent model–independent upper bounds on ALP-leptons couplings for ma in the (sub)–GeV range

Evaluation of the design effects of different agropastoral systems on the diversity and density of spiders

Sustainable agro-ecological design is challenging when the goal is self-regulation of the system. The objective of this study was to evaluate if the agropastoral design system affects the spider community, as spiders are the main predators in these production systems, and to determine those designs which maximize the diversity and density of spiders. The study was conducted during 2009/2010, at the Experimental Research Station of Agriculture (EEA-INTA) Reconquista (Santa Fe, Argentina) where we considered four different designs: C1 (five agricultural fields), C2 (three agricultural fields and four livestock fields), C3 (six agricultural fields and one livestock field) and C4 (five agricultural fields and one forest area). In each design, the spiders were collected by pitfall traps and suction samples with a G-Vac (garden-vacuum). The designs proposed were considered on the basis of environmental heterogeneity. The C4 treatment had the greatest number of species, followed by C2, C3 and C1 (183, 178, 144 and 142 species, respectively), and C2 presented the greatest abundance of spiders followed by C4, C3 and C1 (n=5708, 4785, 4271 and 3448, respectively). Eight guilds were present in C3 and C4. This study is the first to evaluate the diversity of spiders in agropastoral systems in Argentina. Our results show that designs that include more fields with livestock or equal to those for agriculture, as well as forest areas, increase environmental heterogeneity. Therefore, the presence of a biological controller and dominant predatory group will be possible with sustainable designs that have environmental heterogeneity, contributing to improved pest control in agricultural systems

CVARN - Rock art virtual corpus of north-western Portugal. A multimedia tool to investigate and describe post-palaeolithic rock art

The purpose of this paper is the dissemination of the Rock Art Virtual Corpus of the Northwest of Portugal (CVARN), a database dedicated to the theme of Post- Palaeolithic rock art in the Northwest of Portugal, which has been available online since the end of September 2014. This software tool is being built and developed under the ENARDAS project, a scientific project financed by the Thematic Factors of Competitiveness Operational Programme and by the European Regional Development Fund, and has been on-going since 2011, but is now open to the entire scientific community. Apart from being a first compilation of different “styles” of rock arts that occur between the western façade of Iberia, between the basins of the Minho and Vouga rivers, it will have both social and scientific functions. In social terms, the results obtained may contribute to regional development, especially regarding development from the perspective of tourism. In scientific terms, it will allow us to promote scientific research in this field of knowledge and to enable scientifically validated arguments for the integration of rock art sites into tourism evaluation projects.info:eu-repo/semantics/acceptedVersio
