How do your rivals' releasing dates affect your box office?

In this paper, we study to what extent a movie's box office receipts are affected by the temporal distribution of rival films. We propose a theoretical model that analyses the effects of past, present and future releases on a film's results. Using this model we can analyse how rivals' release dates impact on others' box office revenues. This theoretical model also allows us to carry out some comparative statics by changing some relevant parameters such as time depreciation, film quality or the timeline of exhibition. We have tested the empirical implications of this model using information on the films released in five countries: the USA, the United Kingdom, Germany, France and Spain. In order to maintain a degree of homogeneity, we have constructed an unbalanced panel consisting of films that were released in at least three of these countries. The geographical dimension of our data set allows us to use panel data techniques to control for unobserved heterogeneity among the films released. This allows us to control for one of the most relevant features of the movie market, namely the presence of highly differentiated products.temporal competition, movie exhibition, film industry, panel data, unobserved heterogeneity, differentiated product

Evolución del arbolado urbano en dunas bonaerenses

Los cambios espacio-temporales en la ocupación del territorio son procesos dinámicos que deben ser estudiados porque proporcionan la base para conocer las tendencias de los procesos de urbanización. El objetivo del trabajo fue realizar la zonificación geográfica de la evolución de cambios de la cobertura de territorial a partir de la tendencia temporal al sur del Municipio de Villa Gesell. Se realizó un análisis cluster con SIG de fotografías aéreas e imágenes satelitales de los años 1975 – 1997 y 2015, cuyos resultados expresan el aumento del arbolado urbano. Los cambios encontrados favorecieron el desarrollo del turismo con una mejora del paisaje y aportando un elemento blando de conexión entre las tres localidades del eje.The spatio-temporal changes in the occupation of the territory are dynamic processes that must be studied because they provide the base to know the tendencies of the processes of urbanization. The objective of the work was to carry out the geographical zoning of the evolution of changes in territorial coverage based on the temporal trend south of the Municipality of Villa Gesell. A cluster analysis was carried out with GIS of aerial photographs and satellite images of the years 1975 - 1997 and 2015, whose results express the increase of urban trees. The changes found favored the development of tourism with an improvement of the landscape and contributing a soft element of connection between the three localities.Fil: Gaspari, Fernanda J..

Centralidade urbana: configuração espacial e condições socioeconômicas na cidade de São Paulo, Brasil

Este artigo explora São Paulo, a maior cidade da América do Sul. O crescimento da cidade caracteriza-se por um deslocamento do centro urbano em direção ao sudoeste. Este teve consequências deletérias sobre o centro histórico, que sofreu uma deterioração do seu ambiente construído e um aumento da privação socioeconômica. Este artigo examina como a morfologia transformada de São Paulo no século XXI afetou a distribuição socioeconômica e a diversidade demográfica. Ele emprega uma abordagem da sintaxe espacial, que é um conjunto de técnicas e teoria que investiga as relações entre configuração espacial e os fenômenos socioeconômicos. Análises revelam que a morfologia de São Paulo apresenta um “colcha de retalhos”, que são morfologicamente diferenciados pela sua relação de escala com a estrutura urbana maior. As consequências socioeconômicas dessa fragmentação tem sido o aumento da diferenciação de classes sociais consistentes com a sua acessibilidade às concentrações de atividade que ocorrem em diferentes escalas urbanas.This paper explores São Paulo, the largest city in South America. The growth of the city has been characterized by a shift of the urban centre towards the southwest. This had deleterious consequences on the historic centre, which experienced a deterioration of its built environment and an increase in socio-economic deprivation. This paper examines how the transformed morphology of twenty-first century São Paulo affected its socio-economic distribution and demographic diversity. It employs theoretical and methodological space syntax approach, which is a set of techniques and theory that investigates relationships between spatial layout and socio-economic phenomena. The analysis found that the morphology of São Paulo presents a ‘patchwork’ of offset grids, which are morphologically differentiated by their scaled relationship to the larger urban structure. Socioeconomic consequences of this fragmentation have been to increase the differentiation of social classes consistent with their accessibility to concentrations of activity taking place at different scales.Peer Reviewe

Learning contract, co-operative and flipped learning as useful tools for studying metabolism

Es el Abstract de una comunicación a un congreso internacional sobre educaciónUndergraduate students in Biology identify Metabolic Biochemistry as a particularly difficult subject. This is due to the fact that students need to interconnect properly all the contents of its syllabus throughout their study of the subject in order to get a global insight of the complex regulatory features controlling metabolic pathways within the metabolic network under different physiologic and pathologic conditions, as well as metabolism as a whole. Due to these objective difficulties, a high percentage of our students face the study of this subject as a very hard task beyond their forces and capacities. This perception leads to high rates of premature dropout. In previous years, less than 40% of all the registered students attended the examinations of Metabolic Biochemistry (a subject in the second year of the Degree of Biology at our University). Even worse, less than 25% of our students passed the exams. From the academic year 2015/16 on, we are developing innovative teaching projects (PIE15-163 and PIE17-145, funded by University of Malaga) aimed to increase our student loyalty to the subject (and hence to increase their attendance to exams) and to help them to learn more effectively metabolism and its regulation. These innovative teaching projects are based on the use of several powerful tools: a learning contract and problem-based learning within the framework of group tasks promoting an actual collaborative learning in a flipped classroom. The present communication will show the implementation of the PIE15-163 and PIE17-145 projects and some results obtained from them.This work was supported by Malaga University funds granted to the educational innovation project PIE17-145.

Pensando en la salud de niños y niñas, el aporte desde las representaciones sociales/Thinking about Children Health, the Contribution from Social Representations

This paper aims to analyze the concept of child health. This has been a permanent and transversal question for Western society in its effort to specify both the meaning and its scope in the daily experience, as well as in formulating public policies that allow a more accurate action of the actors involved in its consolidation. Being the disease its counterpart, it appears as one of the main concerns that needs to be understood and explained to generate proposals to solve presented problems. The different approaches reiterate the need for children's participation, recognizing their points of view, opinions, imaginaries, representations, emerging categories and constructed theories, which in turn are related to everyday practices and behaviors. Therefore, transformation axis of reflection of the exercise of public health translates into the construction of citizenship by childhood

Maternal Geohelminth Infections Are Associated with an Increased Susceptibility to Geohelminth Infection in Children: A Case-Control Study

Background: Children of mothers infected with soil-transmitted helminths (STH) may have an increased susceptibility to STH infection. Methods and Findings: We did a case-control study nested in a birth cohort in Ecuador. Data from 1,004 children aged 7 months to 3 years were analyzed. Cases were defined as children with Ascaris lumbricoides and/or Trichuris trichiura, controls without. Exposure was defined as maternal infection with A. lumbricoides and/or T. trichiura, detected during the third trimester of pregnancy. The analysis was restricted to households with a documented infection to control for infection risk. Children of mothers with STH infections had a greater risk of infection compared to children of uninfected mothers (adjusted OR 2.61, 95% CI: 1.88–3.63, p,0.001). This effect was particularly strong in children of mothers with both STH infections (adjusted OR: 5.91, 95% CI: 3.55–9.81, p,0.001). Newborns of infected mothers had greater levels of plasma IL-10 than those of uninfected mothers (p = 0.033), and there was evidence that cord blood IL-10 was increased among newborns who became infected later in childhood (p = 0.060). Conclusion: Our data suggest that maternal STH infections increase susceptibility to infection during early childhood, an effect that was associated with elevated IL-10 in cord plasma

Biological parameters of franciscana dolphins, Pontoporia blainvillei, bycaught in artisanal fisheries off southern Buenos Aires, Argentina

The franciscana dolphin (Pontoporia blainvillei) is a small coastal dolphin endemic to the south-western Atlantic ocean. Incidental captures in fishing gillnets is possibly the greatest conservation concern for this species, and occurs within most of its geographical distribution. The aim of this paper is to determine the biological parameters of franciscana dolphin bycaught from artisanal coastal fisheries of the southern Buenos Aires province, Argentina. Between 2003 and 2009, carcasses of 54 incidentally captured franciscanas were collected. The age, sexual and physical maturity and body condition of each specimen was determined. The sex ratio of the bycaught dolphins did not differ from parity and, consistent with other areas, juveniles younger than 4 yr old were captured in higher proportion (69%). In addition, 74% of the entangled animals were sexually immature and 85% physically immature. Sexually immature dolphins were predominant in the spring, a period which coincides with the breeding season. An assessment of the body condition of captured franciscanas suggests that entanglements were not associated with a disease or physiological disorder. The results presented here are important to assess the impact of artisanal fisheries on the population of franciscana dolphins in the southernmost area of its distribution.Fil: Negri, Maria Fernanda.
