How effective are policies to reduce gasoline consumption? evaluating a quasi-natural experiment in Spain

Using a panel of 48 provinces for four years we empirically analyze a series of temporary policies aimed at curbing fuel consumption implemented in Spain between March and June 2011. The first policy was a reduction in the speed limit in highways. The second policy was an increase in the biofuel content of fuels used in the transport sector. The third measure was a reduction of 5% in commuting and regional train fares that resulted in two major metropolitan areas reducing their overall fare for public transit. The results indicate that the speed limit reduction in highways reduced gasoline consumption by between 2% and 3%, while an increase in the biofuel content of gasoline increased this consumption. This last result is consistent with experimental evidence that indicates that mileage per liter falls with an increase in the biofuel content in gasolines. As for the reduction in transit fares, we do not find a significant effect for this policy. However, in specifications including the urban transit fare for the major cities in each province the estimated cross-price elasticity of the demand for gasoline -used as a proxy for car use- with respect to the price of transit is within the range reported in the literature. This is important since one of the main eficiency justification for subsidizing public transit rests on the positive value of this parameter and most of the estimates reported in the literature are quite dated.

Endocarditis infecciosa por estreptococos beta-hemolíticos. Características y curso clínico de una cohorte multinacional.

Se trata de un estudio descriptivo de una cohorte prospectiva y multinacional de pacientes adultos diagnosticados de endocarditis infecciosa, de la cual se seleccionaron los pacientes diagnosticados de endocarditis infecciosa por estreptococos beta-hemolíticos y por estreptococos orales del grupo viridans. Los objetivos del estudio fueron describir las características clínicas, ecocardiográficas y el pronóstico de los pacientes con endocarditis infecciosa causada por estreptococos beta-hemolíticos y comparar dichas características con la endocarditis causada por estreptococos del grupo viridans. Las principales conclusiones fueron que la endocarditis infecciosa por estreptococos beta-hemolíticos es una entidad poco frecuente, que presenta un curso agresivo con una alta frecuencia de complicaciones y una necesidad quirúrgica alta.

Place marketing performance: benchmarking european cities as business destinations

The aim of this study is to develop a model measuring the performance of cities' marketing efforts. The model and the benchmarking methodology presented can be used by local authorities to position their marketing efforts and achievements against other (competing) cities and to identify best practices that can assist place marketers in learning how to be more efficient obtaining desired place marketing results, e.g., improved city brand image, with the available resources/budgets. The major implication for practitioners is that place marketing should be managed as a process, taking into account both the resource flows and the outputs, as well as the efficiency of this process.

Comparación de la prueba de la tuberculina y la prueba del Quantiferón para la detección de infección tuberculosa latente en pacientes candidatos a inmunodepresión.

El objetivo del presente estudio es comparar la prueba de la tuberculina y los IGRAS (concretamente la prueba del Quantiferón) en pacientes candidatos a recibir tratamiento inmunodepresor. Se evalúan 139 pacientes y se obtienen un mayor número de resultados positivos para la prueba de la tuberculina. La conclusión inicial, por tanto, es que ésta es la prueba más sensible, teniendo en cuenta el sesgo provocado por la ausencia de una prueba “gold standard” en la detección de infección tuberculosa latente. No se pueden obviar sin embargo los casos en que resultados negativos de la prueba de la tuberculina que fueron positivos en la prueba del Quantiferón , por lo que se concluye que ambas pruebas son útiles y necesarias en la detección de la infección tuberculosa latente en pacientes candidatos a inmunodepresión.

Educação em saúde para portadores de doença mental: relato de experiência

A experiência descrita no presente texto refere-se a um projeto efetivo de educação em saúde num ambulatório de Saúde Mental em São Paulo, realizado por discentes de Enfermagem. A crença na conquista da cidadania pelo doente mental e a compreensão de que a educação pode tornar-se um dos instrumentos de emancipação dos sujeitos, foram os pressupostos do projeto. Houve uma fase curta e outra prolongada, ocorrendo no formato de grupo semanal aberto a usuários e familiares, com caráter participativo onde todos tinham liberdade, pois o espaço era aberto a discussões com trocas de opinião e experiências. As temáticas abordadas foram referentes às doenças crônicas, destacando dentre estas os transtornos mentais, transmissíveis e crônico-degenerativas.

Guidelines for the use and interpretation of assays for monitoring autophagy.

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

Evidence for mantle exhumation along the Arabian margin in the Zagros (Kermanshah area, Iran)

The Kermanshah Crush Zone (Zagros, Iran) comprises elements from the Tethys Ocean and the former ocean-continent transition. Serpentinites and gabbros exposed in this area were formerly interpreted as originated from Tethys ocean and other residual Tethys oceanic domains all situated northeast of the Bisotoun platform. However, the structural relationships between these ultramafic units remained unclear. New field work in the Kermanshah-Harsin area led to the description of detachment faults over serpentinised mantle. ``Mid-Cretaceous'' carbonate ``extensional allochthons'' (pre-rift) and pelagic sediments (syn- to post-rift) dated from the Liassic are exposed above these detachments. Such an age mismatch can be explained by a polyphased mantle exhumation in a narrow basin along the Arabian margin with the assumption that no radiolarite nappe has been thrusted over the Bisotoun. Another detachment has been identified further to the NE on Eocene gabbro. So far, this one is considered as an intra-oceanic detachment from the residual Tethys. A first evolution model is proposed from early Jurassic to late Cretaceous obduction along with how this interpretation may be improved by future field work.
