Sustainable development in North Bohuslän (Sweden): an analysis in three scales

Partiendo del estudio de la zona que discurre por la carretera E6 en su recorrido desde el municipio de Uddevala, al suroeste de Suecia hasta la frontera con Noruega se analizan las afecciones producidas en los asentamientos y el paisaje. El proyecto se estructura en tres escalas diferentes: regional, intermedia y local para entender la fuerte conexión entre las mismas. A nivel regional se analizan los tipos de paisaje por medio de un inventario utilizando el método PEBOSCA, dentro del programa Hábitat de las Naciones Unidas estudiando todos los recursos (físicos, biológicos, sociales, económicos, organizacionales... ) de una zona determianda ; y el método DAFO (en inglés SWOT)que se ocupa de las fuerzas y debilidades de la región. Se identifican los problemas más importantes, a saber, ampliar los servicios durante todo el año, mejorar la conectividad extendiendo el transporte público y carriles para bicicletas y mejorar la calidad del agua mitigando su efecto barrera. En un nivel intermedio, el proyecto se centra en la localidad de Hogdalsnäset por estar afectado por una falta de estructura urbana y por su proximidad a la frontera con Noruega. En el plano local se analiza la zona de Nordby presentando un plan alternativo de desarrollo a corto, medio y largo plazo. Por último, la autora concluye con la propuesta de construcción del "Parque del Humedal".

The role of children in the traditional religious house-blessing rite of Salpassa in north-eastern Spain

Salpassa denotes the blessing of houses, land, and other belongings, carried out during Easter week and Resurrection (Easter) Sunday in the Valencia–Catalonia linguistic region of north-eastern Spain. Although it is now remembered mostly as a consecrating ceremony or a religious rite, recent field research has shown that a playful element, carried out by children through their songs and other activities, was also an important aspect of the traditional Salpassa.

La migración de retirados europeos al mercado de viviendas español: una evidencia sobre sus efectos

La migración internacional de retirados no es un fenómeno nuevo entre los países de la Unión Europea. Hay un buen número de sociólogos que han descrito el proceso y sus implicaciones en las formas de vida, especialmente en los casos de migración de los hogares de jóvenes retirados desde los países del norte de Europa hacia los soleados del sur. Muchos de estos movimientos afectan al mercado de viviendas desde el mismo momento de la llegada al país de destino y, en muchos casos, los flujos de población generados por esta migración contribuyen al cambio en las tendencias de edificación en los casos en que los destinos tienen bajos niveles de renta. Estos flujos tienen también implicaciones futuras como la necesidad de aumentar los servicios de atención a la tercera edad o en salud lo que, hoy por hoy, implican un elevado gasto público para el sistema español. Este artículo se interesa por las implicaciones en el corto plazo, así como en indagar en el fenómeno en sí. A través de la explotación de parte de los resultados de un proyecto de investigación denominado REVIcVAL (Retirados y vivienda en la Comunidad Valenciana), el artículo muestra algunas características de este flujo migratorio así como la racionalidad a la hora de tomar la decisión de comprar una vivienda. El ejercicio empírico utiliza información primaria recogida a través de un cuestionario recopilando información de retirados ingleses y alemanes en la costa de Alicante durante los años 2005 y 2006, con una base municipal, y estima la racionalidad en la toma de decisión de compra de viviendas.

Planejamento e déficit habitacional: estudo de caso a partir do cadúnico com beneficiários do programa bolsa família na zona norte de Natal

This research aims to analyze the housing conditions and socioeconomic of beneficiaries of the Bolsa Família Program – PBF of the North side of Natal city. For that, it is necessary a survey of this region's origins and how its expansion has occurred in the context of local urban development, considering demographic evolution, in particular, from the construction of housing complex and formal and informal allotments. From the field research, consisting of a pilot in loco with some households, it became possible to start the analysis of housing conditions that culminated with a detailed study of the Single Register form of the federal Government (CadÚnico), in relation to 100% (one hundred percent) of the beneficiaries of the Bolsa Familia program (PBF) of Natal city, with qualitative and quantitative information. From this general survey, a cut was done, contemplating only beneficiaries residing in the north of the city. To better understand this reality, the survey found the Brazilian housing deficit, considering its origins, historical contexts and concepts used by the following institutions: João Pinheiro Foundation (FJP), Brazilian Institute of Geography and Statistics (IBGE), Applied Economics Research Institute (IPEA), and Local Plan Housing of Social Interested (PLHIS) and the United Nations Centre for Human Settlements (UN-HABITAT). Furthermore, were compared the various concepts of city and its respective evolution, considering the importance of planning as an instrument of public policy necessary to governmental actions and permanent policy of State. As a result, there are a detach about the deficit and housing conditions in the city of Natal, mainly North Zone, pointing out the importance of using the Unified Register of the federal government as an effective tool to measure the living conditions of Brazilian municipalities.

Malaria prevention in north-eastern Tanzania: patterns of expenditure and determinants of demand at the household level.

Objective. This study aims to provide a better understanding of the amounts spent on different malaria prevention products and the determinants of these expenditures. Methods. 1,601 households were interviewed about their expenditure on malaria mosquito nets in the past five years, net re-treatments in the past six months and other expenditures prevention in the past two weeks. Simple random sampling was used to select villages and streets while convenience sampling was used to select households. Expenditure was compared across bed nets, aerosols, coils, indoor spraying, using smoke, drinking herbs and cleaning outside environment. Findings. 68% of households owned at least one bed net and 27% had treated their nets in the past six months. 29% were unable to afford a net. Every fortnight, households spent an average of US $0.18 on nets and their treatment, constituting about 47% of total prevention expenditure. Sprays, repellents and coils made up 50% of total fortnightly expenditure (US$0.21). Factors positively related to expenditure were household wealth, years of education of household head, household head being married and rainy season. Poor quality roads and living in a rural area had a negative impact on expenditure. Conclusion. Expenditure on bed nets and on alternative malaria prevention products was comparable. Poor households living in rural areas spend significantly less on all forms of malaria prevention compared to their richer counterparts. Breaking the cycle between malaria and poverty is one of the biggest challenges facing malaria control programmes in Africa.

Rethinking Care Through Social Reproduction: Articulating Circuits of Migration

Care has come to dominate much feminist research on globalized migrations and the transfer of labor from the South to the North, while the older concept of reproduction had been pushed into the background but is now becoming the subject of debates on the commodification of care in the household and changes in welfare state policies. This article argues that we could achieve a better understanding of the different modalities and trajectories of care in the reproduction of individuals, families, and communities, both of migrant and nonmigrant populations by articulating the diverse circuits of migration, in particular that of labor and the family. In doing this, I go back to the earlier North American writing on racialized minorities and migrants and stratified social reproduction. I also explore insights from current Asian studies of gendered circuits of migration connecting labor and marriage migrations as well as the notion of global householding that highlights the gender politics of social reproduction operating within and beyond households in institutional and welfare architectures. In contrast to Asia, there has relatively been little exploration in European studies of the articulation of labor and family migrations through the lens of social reproduction. However, connecting the different types of migration enables us to achieve a more complex understanding of care trajectories and their contribution to social reproduction.

Burned Area Mapping in the North American Boreal Forest Using Terra-MODIS LTDR (2001–2011): A Comparison with the MCD45A1, MCD64A1 and BA GEOLAND-2 Products

An algorithm based on a Bayesian network classifier was adapted to produce 10-day burned area (BA) maps from the Long Term Data Record Version 3 (LTDR) at a spatial resolution of 0.05° (~5 km) for the North American boreal region from 2001 to 2011. The modified algorithm used the Brightness Temperature channel from the Moderate Resolution Imaging Spectroradiometer (MODIS) band 31 T31 (11.03 μm) instead of the Advanced Very High Resolution Radiometer (AVHRR) band T3 (3.75 μm). The accuracy of the BA-LTDR, the Collection 5.1 MODIS Burned Area (MCD45A1), the MODIS Collection 5.1 Direct Broadcast Monthly Burned Area (MCD64A1) and the Burned Area GEOLAND-2 (BA GEOLAND-2) products was assessed using reference data from the Alaska Fire Service (AFS) and the Canadian Forest Service National Fire Database (CFSNFD). The linear regression analysis of the burned area percentages of the MCD64A1 product using 40 km × 40 km grids versus the reference data for the years from 2001 to 2011 showed an agreement of R2 = 0.84 and a slope = 0.76, while the BA-LTDR showed an agreement of R2 = 0.75 and a slope = 0.69. These results represent an improvement over the MCD45A1 product, which showed an agreement of R2 = 0.67 and a slope = 0.42. The MCD64A1, BA-LTDR and MCD45A1 products underestimated the total burned area in the study region, whereas the BA GEOLAND-2 product overestimated it by approximately five-fold, with an agreement of R2 = 0.05. Despite MCD64A1 showing the best overall results, the BA-LTDR product proved to be an alternative for mapping burned areas in the North American boreal forest region compared with the other global BA products, even those with higher spatial/spectral resolution

Discrimination in the Private Sphere. A subjective Right or a Legal Abuse. An European North American Legal Comparative Study

En el presente trabajo se estudian los límites de la autonomía privada desde la perspectiva del derecho a la igualdad y del principio de no discriminación tanto en el derecho norteamericano como en el europeo, con especial incidencia a la doctrina española. Por un lado se plantea si la piedra angular a la hora de establecer límites a la autonomía privada debe ser el concepto de dignidad o el de igualdad, por otro superando dicho debate se propone un acercamiento al problema entendido como una colisión entre derechos fundamentales en la que en cada concreto supuesto ha de estudiarse cual debe prevalecer. Finalmente se estima conveniente seguir el modelo de la Constitución de Sudáfrica y entender que los derechos fundamentales afectan directamente tanto a las relaciones horizontales como verticales, es decir tanto al ámbito público como privado.

Soil characteristics in Doon Valley (north west Himalaya, India) by inversion of H/V spectral ratios from ambient noise measurements

Past and recent observations have shown that the local site conditions significantly affect the behavior of seismic waves and its potential to cause destructive earthquakes. Thus, seismic microzonation studies have become crucial for seismic hazard assessment, providing local soil characteristics that can help to evaluate the possible seismic effects. Among the different methods used for estimating the soil characteristics, the ones based on ambient noise measurements, such as the H/V technique, become a cheap, non-invasive and successful way for evaluating the soil properties along a studied area. In this work, ambient noise measurements were taken at 240 sites around the Doon Valley, India, in order to characterize the sediment deposits. First, the H/V analysis has been carried out to estimate the resonant frequencies along the valley. Subsequently, some of this H/V results have been inverted, using the neighborhood algorithm and the available geotechnical information, in order to provide an estimation of the S-wave velocity profiles at the studied sites. Using all these information, we have characterized the sedimentary deposits in different areas of the Doon Valley, providing the resonant frequency, the soil thickness, the mean S-wave velocity of the sediments, and the mean S-wave velocity in the uppermost 30 m.

Local Use and Management of Tasba (Senna obtusifolia) in the Traditional Food System of Sanguere Paul, North Cameroon

The purpose of this study is to examine the importance of the wild edible weed tasba (Senna obtusifolia) in Sanguéré Paul, Cameroon by examining how households use and manage the plant. This study found that local management of tasba is minimal compared to other traditional vegetables. Tasba was collected most frequently from en brousse or the communal, fallowed land which is often too degraded for traditional field crops to grow. Women subsistence farmers were closely involved with tasba as they are the ones responsible for food production within the family. Socioeconomic differences between women affects how they manage tasba and other vegetables to form a livelihood strategy to achieve food security within the family. Modifications and changes in management and use of tasba are influenced by time, proximity and income based on her perspective, preferences and resources available. Overall, tasba is an integral part of the traditional food system in Sanguéré Paul, and can play a role in the uncertain ecological and social setting of northern Cameroon.

North-eastern Morocco: a high geothermal prospect.

New temperature data obtained in 2007 in a hydrogeological borehole (1100 m deep) near Berkane have revealed an average geothermal gradient of about 126°C/km at depths greater than 300 m. This result confirms the average geothermal gradient estimated in a mining borehole located about 30km west of the Berkane borehole, in which water with temperatures as high as 96°C was reached at a depth of about 700 m. The new geothermal gradient, exceeding by far the ones already determined for this Moroccan area allows thinking about the possibility of programs for using high temperature waters in north-eastern Morocco.
