Behavioural and physiological responses of shelter dogs to long-term confinement

In Italy, National Law (281/1991) prohibits euthanasia of shelter dogs if they are not dangerous or suffering seriously. Adoption rates in rescue shelters are often lower than entrance rates, leading inevitably to overcrowded facilities where animals are likely to spend the rest of their lives in kennels. In this situation, housing conditions (i.e. space provided, environmental, and social stimulation) may have an impact on canine welfare. In this research project, the effects of two different forms of housing (group- and pair housing) on long-term shelter dogs were compared using behavioural and physiological parameters. Observational data and saliva samples were collected from dogs exposed to both experimental settings; behaviour and cortisol concentration levels were used as welfare indicators. Pair housing offered fewer social and environmental stimuli and behavioural analysis showed a significant decrease in locomotor, exploratory, and social behaviour. Cortisol levels show that this parameter varied independently of housing conditions. Although this study found no evidence suggesting that one form of confinement reduced animal welfare more than the other (e.g. in terms of abnormal behaviour, or higher cortisol concentrations), the type of confinement did affect the expression of a variety of behaviours and these variations should not be ignored with respect to housing decisions for long-term shelter dogs.

Refugee crisis and re-emergence of forgotten infections in Europe

Makeshift shelters are becoming increasingly evident in European cities as a consequence of the momentous influx of refugees seeking asylum in European countries. These individuals have endured long gruelling journeys to reach their target countries, often having to have survived appalling living conditions (figure 1a). One of the routes chosen by migrants is that from East Africa, through Sudan and Libya before reaching North Africa and eventually Europe (see figure 1b). Not unsurprisingly, this has led to the introduction of infectious diseases rarely encountered in developed nations, most notably louse-borne relapsing fever (LBRF).

Modelling antropogenic impact on primary production of sado estuary

The assessment of human impact on complex estuarine systems is a multidisciplinary task that is highly demanding in terms of measurements and fieldwork. Nowadays the use of inexpensive and reliably modeling tools can substantially reduce the amount of measurements needed to characterize a system. These tools are also a convenient way to forecast the future evolution of the system and to study the impact of different scenarios of human influence. In this communication a modeling system composed by hydrodynamic, transport and ecological models is used to assess the current trophic state of Sado Estuary (Portugal) and to predict the future trends of the system based on different scenarios of human intervention. Special care is taken to the impact of changing riverine nutrient loads. Sado estuary is a large European estuary that has been considered until now in good trophic conditions with eutrophication appearing only in some isolated spots. Nevertheless in recent years some studies point out that the situation is changing. Sado estuary is a system with strong environmental opposing interests. It hosts a major industrial and urban center around the city of Setúbal and the upper reaches are used to intensive cultures such as rice. On the other hand the estuary possess an important ecological value since it is used by several important species of fish as a spawning and nursery area and it’s wetlands are used by many species of birds as winter shelters. Due to it’s importance the majority of Sado Estuary is considered as Natural Reserve.

Inventories and concentration profiles of 137Cs in undisturbed soils in the northeast of Buenos Aires Province, Argentina

Inventories and vertical distribution of (137)Cs were determined in La Plata region undisturbed soils, Argentina. A mean inventory value of 891 ± 220 Bq/m(2) was established, which is compatible with the values expected from atmospheric weapon tests fallout. The study was complemented with pH, organic carbon fraction, texture and mineralogical soil analyses. Putting together Southern Hemisphere (137)Cs inventory data, it is possible to correlate these data with the mean annual precipitations. The large differences in (137)Cs concentration profiles were attributed to soil properties, especially the clay content and the pH values. A convection-dispersion model with irreversible retention was used to fit the activity concentration profiles. The obtained effective diffusion coefficient and effective convection velocity parameters values were in the range from 0.2 cm(2)/y to 0.4 cm(2)/y and from 0.23 cm/y to 0.43 cm/y, respectively. These data are in agreement with values reported in literature. In general, with the growth of clay content in the soil, there was an increase in the transfer rate from free to bound state. Finally, the highest transfer rate from free to bound state was obtained for soil pH value equal to 8.

Particulate matter flux deposition in the vicinity of a coal-fired power plant

This paper describes the methodology adopted to assess local air quality impact in the vicinity of a coal power plant located in the south of Portugal. Two sampling areas were selected to assess the deposition flux of dust fallout and its potential spatial heterogeneity. The sampling area was divided into two subareas: the inner, with higher sampling density and urban and suburban characteristics, inside a 6-km circle centered on the stacks, and an outer subarea, mainly rural, with lower sampling density within a radius of 20 km. Particulate matter deposition was studied in the vicinity of the coal fired power plant during three seasonal sampling campaigns. For the first one, the average annual flux of dust fallout was 22.51 g/(m2 yr), ranging from 4.20 to 65.94 g/(m2 yr); for the second one was 9.47 g/(m2 yr), ranging from 0.78 to 32.72 g/(m2 yr) and for the last one was 38.42 g/(m2 yr), ranging from 1.41 to 117.48 g/(m2 yr). The fallout during the second campaign turned out to be much lower than for others. This was in part due to meteorological local patterns but mostly due to the fact that the power plant was not working at full power during the second sampling campaign.155

Heróis de palmo e meio: a intervenção psicossocial e a relação de ajuda no acolhimento institucional

Os Lares de Infância e Juventude têm como objetivo defender o superior interesse das crianças, desempenhando um papel fundamental no acompanhamento do seu desenvolvimento. Este dever concretiza-se substancialmente na definição e acompanhamento dos seus projetos de vida. Neste sentido, as práticas dos profissionais devem ir ao encontro das reais necessidades dos seus atores, numa ação adequada, desenhada e concertada, tendo sempre como principio básico o respeito pelas idiossincrasias de cada criança e jovem. O presente Relatório tem como objetivo apresentar o desenho e desenvolvimento de um projeto de intervenção psicossocial e relação de ajuda com crianças em acolhimento institucional, intitulado “Heróis de Palmo e Meio. A intervenção psicossocial e a relação de ajuda no acolhimento institucional”. Este projeto teve como grande finalidade a “Participação das crianças e das suas famílias na construção dos seus projetos de vida com base na compreensão da institucionalização”. Priorizando as necessidades e respeitando o critério de urgência, foram desenhados dois subprojectos com duas crianças e suas famílias, tentando sempre responder às suas necessidades individuais. Foram definidos alguns objetivos gerais comuns, assim como objetivos específicos, estratégias e ações adequadas a cada um dos subprojectos. Os resultados deste projeto revelam-se significativos, já que permitiram, quer às crianças, quer às famílias, desenvolver um processo de reflexão e consciencialização em torno da sua história de vida, compreensão da sua realidade e participação ativa no projeto de vida dos filhos, o que veio facilitar o caminho inicial do processo da mudança.

Évaluation des écosystèmes en début de millénaire: conclusions et retombées

L'évaluation des écosystèmes est l'un des pivots essentiels pour l'élaboration de moyens adaptés permettant de lutter contre la diminution massive de la biodiversité. Pour la première fois, elle a fait l'objet d'une analyse à l'échelle mondiale dans le cadre de l'Evaluation des écosystèmes en début de millénaire (EM). Le rassemblement de plus d’un millier de chercheurs et de plusieurs organismes internationaux durant quatre années ont permis de dessiner la carte nécessaire à toute action efficace. L'article expose les éléments principaux de l'EM : l'évaluation des écosystèmes en tant que tels, mais surtout des services écosystémiques, dans toutes leurs dimensions, en ce que leur évolution affecte le bien-être humain. Il analyse ensuite les quatre points principaux de l'apport de l'EM, des avantages de l'utilisation croissante des services écologiques à sa non viabilité. Des scénarios, modèles et outils sont proposés pour inverser la courbe négative d'appauvrissement de la biodiversité et des services écosystémiques dans un premier bilan des retombées de l'EM.

Étude exploratoire du conflit de loyauté chez des enfants exposés à la violence conjugale

Résumé Le but de cette recherche est de comprendre le conflit de loyauté chez les enfants exposés à la violence conjugale lorsque les parents sont séparés. Le premier objectif vise à décrire le contexte relationnel de l’enfant avec son père et sa mère. Le second objectif cherche à évaluer la présence et à décrire, le cas échéant, la nature du conflit de loyauté et ses conséquences chez l’enfant. Un troisième objectif porte sur l’identification de sous-groupes d’enfants similaires quant à leur discours sur le conflit de loyauté. Enfin, l’objectif final consiste à décrire un possible changement d’intensité du conflit de loyauté dans le temps. La recherche adopte une méthode qualitative pour recueillir le point de vue des enfants sur un possible vécu de conflit de loyauté des enfants entre leur père et leur mère. Douze enfants, ayant reçu des services d’intervention en maison d’hébergement, donnent leur point de vue sur leur expérience de conflit de loyauté. L’opinion de leur mère raconte l’histoire d’exposition à la violence conjugale de l’enfant ainsi que sa relation avec chacun des deux parents. La perception des intervenantes sur un possible conflit de loyauté chez l’enfant ainsi que sur sa relation avec chacun de ses parents vient enrichir cette recherche. Une description du contexte relationnel de l’enfant avec son père et sa mère démontre que la relation des enfants avec leur père ne semble pas toujours facile, alors que celle de l’enfant avec sa mère est plus positive. Les intervenantes jugent que les douze enfants vivent un conflit de loyauté, alors qu’un seul de ces participants verbalise ne pas en vivre. Une première analyse qualitative du discours des enfants a permis de constater qu’aucun des onze enfants n’identifie le père ou la mère comme étant le seul initiateur du conflit de loyauté. Comme résultat des verbalisations des enfants, deux groupes sont formés selon le degré d’élaboration du discours (élaboré ou non élaboré). Les résultats principaux permettent de constater que le degré de conflit de loyauté initié par les mères demeure stable dans le temps alors qu’il s’intensifie lorsqu’initié par certains pères de l’étude.

Les trajectoires de femmes victimes de violence conjugale : les facteurs qui expliquent la dynamique de la violence physique à travers le temps.

La violence conjugale peut prendre différentes formes et évoluer à travers le temps. On ne peut écarter la possibilité que les différentes trajectoires soient influencées par le contexte de vie dans lequel la victime se présente. Dans cet ordre d’idée, la perspective des parcours de vie se présente comme un cadre théorique approprié pour comprendre les différents changements temporels qui s’opèrent dans les trajectoires de victimisation en contexte conjugal. Toutefois, le soutien empirique sur les facteurs derrière le nombre d’épisodes de la violence et ses variations au fil du temps est mince; notamment en raison de la rareté des données longitudinales ou rétrospectives requises pour ce type de recherche. Cette étude propose de combler ces lacunes dans l’analyse des trajectoires individuelles des femmes qui ont été victimes de violence conjugale. Plus spécifiquement, elle analyse l’évolution de l’occurrence et de l’intensité de la violence physique à travers le temps. L’échantillon est composé de 53 femmes, toutes victimes de violence conjugale au courant des 36 derniers mois référées par plusieurs milieux (par exemple : maisons d’hébergement, Cour municipale, centres d’aide aux victimes d’acte criminel, centres de thérapie, maisons de transition). Cette recherche est basée sur des données rétrospectives des circonstances entourant la vie de ces femmes au cours des 36 derniers mois. Les trajectoires individuelles ont été reconstruites en utilisant la méthode des calendriers d’histoire de la vie. Cette méthode qui a fait ses preuves dans l’étude des carrières criminelles et de la victimisation permet de situer les trajectoires dans leur contexte de vie et de reconstruire la dynamique derrière les victimisations. L’utilisation de la modélisation de type multiniveaux comme stratégie d’analyse est privilégiée dans cette étude. Combiné avec le calendrier d’histoire de vie, ce type de modèle permet d’examiner les changements dans la chronicité et l’intensité de la violence au sein des trajectoires individuelles des victimes. Les résultats permettent une meilleure compréhension des éléments statiques et dynamiques dernières trajectoires des femmes victimes. Cette recherche se veut avant tout exploratoire et ouvre la porte à une multitude de possibilités à de futures recherches.

Natural resources, redistribution and Human capital formation

How do resource booms affect human capital accumulation? We exploit time and spatial variation generated by the commodity boom across local governments in Peru to measure the effect of natural resources on human capital formation. We explore the effect of both mining production and tax revenues on test scores, finding a substantial and statistically significant effect for the latter. Transfers to local governments from mining tax revenues are linked to an increase in math test scores of around 0.23 standard deviations. We find that the hiring of permanent teachers as well as the increases in parental employment and improvements in health outcomes of adults and children are plausible mechanisms for such large effect on learning. These findings suggest that redistributive policies could facilitate the accumulation of human capital in resource abundant developing countries as a way to avoid the natural resources curse.

Patrimonis fràgils: la fragilitat dels refugis pirinencs

Els refugis d’alta muntanya per a excursionistes i alpinistes construïts durant les primeres dècades del segle XX són, sens dubte, un dels patrimonis arquitectònics més fràgils de les comarques pirinenques. Les ruïnes del vell refugi d’Ulldeter que projectà el 1907 Jeroni Martorell per al Centre Excursionista de Catalunya (CEC) en són una prova ben punyent

Las cuevas prehistóricas de Serinyà (Pla de l’Estany, Girona)

The Reclau Caves, which form part of the Serinyà Prehistoric Caves Park (Pla de l’Estany, Girona), are shelters formed by waterfall travertines which have been in turn affected by karstification phenomena. Though relatively small, these cavities were big enough to held human occupation. Its evolution has seen the falling of blocks and infilling of terrigenous materials. Thus, the caves were completely filled and had most of their original roofs fallen. The first excavations of these caves were made in the mid 1940s and they continued, albeit with some interruptions, until present times. The caves were occupied by humans since the late Middle Pleistocene until the Holocene. Hence, the main occupation periods can be attributed to the Middle Paleolithic and Upper Paleolithic cultures. Given the existence of these sites, the project of an archeological park was started and its first phase opened to the public in the summer of 1997. The creation of this park has led to the protection of the three main caves of the site (Arbreda, Mollet and Reclau Viver Caves). The caves have also been adapted and singposted to open them to the public. Other facilities of the park include a reception building and an activity area. The caves can be visited in guided tours which include the projection of a film, the visit to the permanent exhibition room, the three main caves and the participation in some prehistoric-related activities
