El Treball Social davant l'explotació sexual femenina
2022
L’article que presentem té com a objectiu conèixer tot allò que hi ha darrere de la demanda i consum de prostitució femenina. Això mateix ens plantegem quina ha de ser la posició del Treball social davant del sistema prostitucional The article we are presenting aims to know everything behind the demand and consumption of female prostitution. We also consider what the position of Social Work should be in the prostitutional system
La explotación sexual de mujeres en la actualidad
2022
Los tiempos de crisis son el terreno abonado para situaciones de explotación de personas en situación de vulnerabilidad como son las mujeres y niñas victimas de prostitución y trata. Durante el confinamiento provocado por el covid-19 todo hacia pensar que nuestra sociedad se paralizaba totalmente y por las restricciones de movilidad. La comunicación que presentamos tiene como objetivo conocer la demanda y el consumo de prostitución durante el confinamiento y cuales han sido las dificultades vividas por las mujeres prostituidas. Times of crisis are the fertile ground for situations of exploitation of people in vulnerable situations such as women and girls victims of prostitution and traffick…
El cuerpo materno en la red: entre el orden de lo ?deseable? y el de lo real
2019
El estilo de vida fitness se realiza en, y a través de, un entramado subjetivo y de poder en el que circulan y se ensamblan dispositivos empresariales, terapéuticos, sanitarios y de espectacularización de los cuerpos, tendientes a inscribir la vida de la población en las tramas conflictivas de un capitalismo heterosexista, neoliberal e informacional. En dicho marco, la temporalidad, metamorfosis y plasticidad del cuerpo materno irrumpe como problema y objeto de intervención de tecnologías diversas orientadas a ajustar su tamaño, forma y devenir a los parámetros de la vida activa y saludable. En escenarios digitales, dicha tensión se materializa, por un lado, a través de dispositivos visuale…
Testing flow resistance equation for rill flow
2018
At first, in this paper a flow resistance equation for rill flow, deduced applying dimensional analysis and self-similarity theory, is presented. The incomplete self-similarity hypothesis is used for establishing the flow velocity distribution whose integration gives the theoretical expression of the Darcy-Weisbach friction factor. Then the deduced theoretical resistance equation, which is calibrated by some measurements of flow velocity, water depth, cross section area, wetted perimeter and bed slope carried out in 106 reaches of some rills modelled on an experimental plot, is tested using the literature data by Abrahams et al. (1996), Strohmeier et al. (2014) and Peng et al. (2015) for ri…
Institutions et mécanismes de gouvernance des transactions :
2013
Institutions and governance mechanisms for transactions : the case of logging in Cameroon Following Masahiko Aoki (2010), we postulate that transactions between actors integrate not only an economic dimension but also a social dimension. This means that transactions’ equilibrium cannot be analyzed only in economic terms. They also include relational aspects that we define as social aspects. Through the study of a local forestry exploitation in Cameroon compared with a communal forestry exploitation in France, we highlight two crucial factors : the dissociation of the functions of mayor and chief of village and the coexistence of payments in cash and payments in nature. The first factor unde…
Efecto de la formalización y la confianza organizativa sobre la capacidad de ambidestreza. Estudio empírico en la industria agroalimentaria ecológica…
2018
Durante las últimas décadas, la ambidestreza ha despertado gran interés entre las organizaciones y los académicos. Para obtener una perspectiva completa del concepto de ambidestreza, investigaciones recientes han sugerido el estudio en profundidad de sus antecedentes. Estudios previos enfatizan que la ambidestreza necesita mecanismos de integración y factores contextuales para aumentar los flujos de conocimiento a través de las unidades organizativas de explotación y exploración (Gibson & Birkinshaw, 2004; Jansen, Tempelaar, Van den Bosch & Volberda, 2009). Sobre la base de una extensa revisión de la literatura, creemos que la formalización y la confianza se destacan como variables claves p…
¿Cabe hablar de una «generación de la crisis»? Discusión en torno a una noción sobreexplotada
2018
This article states that nowadays there is an overuse (or a misuse) of the «Generation» idea. The discussion among many authors over the «Generation of crisis» concept suggests that it is useful to outline the characteristics of the target of population of the collective of youth who are mainly affected by the economic and social crisis over the past years. Nevertheless, through analyzing the meanings of the «Generation of Crisis» made by Mannheim, Ortega and other classic authors, it is clear that the social class approach together with the generational one are needed to define this concrete concept. The conclusion of the articleis that both approaches are seen as underpinning their utilit…
Habitat type and island identity as drivers of community assembly in an archipelago
2020
Aim: Ecoinformatics offer new opportunity to test islands as biogeographic and eco- logical models. In this paper we predicted three hypotheses: (1) plot-based data issu- ing from vegetation surveys can be used to predict Island Species-Area Relationships (ISARs) or island similarity; (2) the habitat area is an independent predictor of species richness patterns within island; (3) species richness and composition are more de- pendent on habitat type than island identity in land-bridge islands. Area: Tuscan Archipelago, Italy. Methods: We assembled a database of all the vegetation plots available for the archi- pelago. For the first hypothesis we calculated ISARs, using Arrhenius model, and B…
Experiments for testing soil texture effects on flow resistance in mobile bed rills
2018
Abstract In this paper a recently theoretically deduced rill flow resistance equation, based on a power-velocity profile, was tested experimentally on plots of varying slopes and soil texture in which mobile bed rills are incised. Measurements of flow velocity, water depth, cross section area, wetted perimeter and bed slope conducted in rill reaches incised on experimental plots, having different slope values (9, 14, 22, 24 and 26%) and soil texture (clay fraction ranging from 42 to 73%), and literature data were used to calibrate the flow resistance equation. In particular, the relationship between the velocity profile parameter Γ, the channel slope, the flow Froude number and texture frac…
An automatic approach for rill network extraction to measure rill erosion by terrestrial and low‐cost unmanned aerial vehicle photogrammetry
2019
For an erosion event (October 2016) occurred at the Sparacia experimental area (Southern Italy), both terrestrial and low-altitude aerial surveys were carried out by consumer grade camera and quadcopter (low-cost unmanned aerial vehicle [UAV]) to measure rill erosion on two plots with steepness of 22% and 26%. Applying the structure from motion (SfM) technique, the three-dimensional digital terrain models (3D-DTMs) and the quasi three-dimensional models (2.5D-digital elevation model [DEM]) were obtained by the two surveys. Furthermore, 3D-DTM and DEM were built using the available aerial photographs (166) and adding 40 terrestrial photographs. For the first time, the convergence index was a…
