Este trabajo surge de la experiencia desarrollada en Barcelona, Zaragoza y Lisboa de puesta en marcha de los respectivos sistemas de información del Arte Público de estas ciudades, así como del desarrollo de investigación posibilitado por los proyectos BHA2002- 00520;HUM2005-00420;HUM2006-12803-C02-01, HAR 2009-13989-C02-01, del Ministerior de Ciencia e Innvoción español y de los proyectos 2005SGR00150 y 2009SGR903 de la Generalitat de Catalunya, así como de los distintos convenios entre la Universidad y el Ayuntamiento de Barcelona. Sorprendentemente, en el panorama de la innovación internacional, son proyectos del sur de Europa los que plantean por primera vez un uso sistemático de Internet para el mejor conocimiento y difusión de esta parte del patrimonio que es el Arte Público de las ciudades, una historia escrita en bronce y piedra que forma parte de la herencia cultural, de las raíces identitarias y del orgullo de ciudad Sin embargo, la crisis internacional supone un frenazo importante a estos proyectos y a la posibilidad de desarrollar un Museo Virtual del Arte Público y el Diseño Urbano.

Background: Antiretroviral therapy has changed the natural history of human immunodeficiency virus (HIV) infection in developed countries, where it has become a chronic disease. This clinical scenario requires a new approach to simplify follow-up appointments and facilitate access to healthcare professionals. Methodology: We developed a new internet-based home care model covering the entire management of chronic HIV-infected patients. This was called Virtual Hospital. We report the results of a prospective randomised study performed over two years, comparing standard care received by HIV-infected patients with Virtual Hospital care. HIV-infected patients with access to a computer and broadband were randomised to be monitored either through Virtual Hospital (Arm I) or through standard care at the day hospital (Arm II). After one year of follow up, patients switched their care to the other arm. Virtual Hospital offered four main services: Virtual Consultations, Telepharmacy, Virtual Library and Virtual Community. A technical and clinical evaluation of Virtual Hospital was carried out. Findings: Of the 83 randomised patients, 42 were monitored during the first year through Virtual Hospital (Arm I) and 41 through standard care (Arm II). Baseline characteristics of patients were similar in the two arms. The level of technical satisfaction with the virtual system was high: 85% of patients considered that Virtual Hospital improved their access to clinical data and they felt comfortable with the videoconference system. Neither clinical parameters [level of CD4 + T lymphocytes, proportion of patients with an undetectable level of viral load (p = 0.21) and compliance levels 90% (p = 0.58)] nor the evaluation of quality of life or psychological questionnaires changed significantly between the two types of care. Conclusions: Virtual Hospital is a feasible and safe tool for the multidisciplinary home care of chronic HIV patients. Telemedicine should be considered as an appropriate support service for the management of chronic HIV infection.

Objetivo: Evaluar la calidad de vida (CV) global en personas con demencia e investigar las variables asociadas con la percepción subjetiva de la CV. Pacientes y métodos: Se llevó a cabo un estudio transversal en seis centros de Barcelona y Tarragona. Un total de 99 personas con demencia leve-moderada que vivían en casa con un cuidador conocido completaron una entrevista cara-cara que incluía información sociodemográfica, percepción del estado de salud, un listado de problemas crónicos de salud, sintomatología depresiva, estado funcional, aspectos positivos, sentido de la vida y satisfacción con las relaciones personales. La CV global se evaluó con la pregunta global del World Health Organization Quality of Life-BREF. Resultados: El 40,6% de los entrevistados consideró su CV como buena/muy buena. Los análisis univariados de regresión logística ordinal y binaria no mostraron asociación entre CV con datos sociodemográficos, gravedad de la demencia ni estado funcional, pero sí con las otras variables de estudio. Los análisis multivariados de la regresión logística ordinal y binaria mostraron que una mejor percepción de salud y mayor satisfacción con las relaciones personales se asociaban con mejor CV. Asimismo, en el análisis multivariado de regresión logística ordinal, mejor CV se asoció con un menor número de síntomas depresivos, y en el análisis de regresión logística binaria, con disfrutar de la vida y menor gravedad de la demencia. Conclusiones: Personas con demencia leve-moderada pueden informar sobre su CV y estados subjetivos. Además de los aspectos relacionados con la salud, aspectos positivos y las relaciones personales deberían evaluarse sistemáticamente en esta población.

This article examines the determinants of traffic volumes and the revenues per tonne generated by Spain’s port authorities. The interest of the study lies on the strong differences between port authorities in a context of strict regulation but that provides some scope for price competition. We find that port charges influence the amount of traffic that a port is able to generate. Furthermore, we find clear evidence of local price competition and report mixed results for global competition. Revenues per tonne are higher in ports operating more international regular lines and with multinational terminal operators, while they are lower in ports with nearby competing facilities and where the market share of the dominant shipping firm is high.

Considered as a remedy to multiple problems that our world is facing, biofuels are nowadays promoted on a global scale. Despite this globalised approach, however, biofuels are heavily contested. Not only the social implications of biofuels are disputed and uncertain, particularly in countries of the global South, but also their environmental and economic rationales. Given these huge controversies, policies promoting biofuels would seem difficult to maintain. Yet, support for them has been surprisingly well established on the political agendas. With the aim of understanding this puzzle, this study asks how the dominant approach to biofuels has been sustained on a global level. In order to answer this question, the meanings and assumptions in biofuel discourses are explored through the lens of Maarten Hajer’s “argumentative” discourse analysis. Based on the existence of a “partnership for sustainable bioenergy” between the EU, Brazil and Mozambique, the study takes these three locations as case studies. The analysis reveals that various discursive strategies, including a particular problem construction and the use of two main story-lines, have played an important role in ensuring the permanence of the global approach to biofuels. Moreover, while the discourse of critics against biofuels demonstrates that there is room for contestation, the analysis finds that the opponents’ discourse largely fails to target the most salient justification for biofuels. A more effective strategy for critics would therefore be to also question the problem constructions underpinning this main justification in the global discourse.

When a flash is presented aligned with a moving stimulus, the former is perceived to lag behind the latter (the flash-lag effect). We study whether this mislocalization occurs when a positional judgment is not required, but a veridical spatial relationship between moving and flashed stimuli is needed to perceive a global shape. To do this, we used Glass patterns that are formed by pairs of correlated dots. One dot of each pair was presented moving and, at a given moment, the other dot of each pair was flashed in order to build the Glass pattern. If a flash-lag effect occurs between each pair of dots, we expect the best perception of the global shape to occur when the flashed dots are presented before the moving dots arrive at the position that physically builds the Glass pattern. Contrary to this, we found that the best detection of Glass patterns occurred for the situation of physical alignment. This result is not consistent with a low-level contribution to the flash-lag effect.

Des que es va iniciar el segle, i a causa dels grans fluxos migratoris de procedències diverses, la població de Catalunya s’ha incrementat en més d’1 milió d’habitants. Diferents actors socials reivindiquen que un dels reptes presents en la societat catalana és reduir les diferències i en alguns casos les desigualtats que es detecten entre la població autòctona i la població d’origen estranger. Amb tot això, diversos autors afirmen que l’espai d’Educació Física de Primària és un espai òptim per atendre a la diversitat cultural, promoure els valors humans, la no discriminació entre l'alumnat i la cohesió i inclusió social. Amb tot aquest marc, apareix el professorat d’Educació Física de Primària i la competència intercultural com a agents de canvi per tal de promocionar la inclusió social en les seves sessions i de retruc en societat. En aquest Treball de Fi de Grau, s’intentarà analitzar i aportar solucions sobre algunes de les qüestions que afecten tant als Mestres d’Educació Física de Primària com a la competència intercultural a l’hora de promocionar la inclusió social del col•lectiu Marroquí, ja que aquest és més nombrós de població estrangera empadronada a Catalunya.

Genetic tools have greatly aided in tracing the sources and colonization history of introduced species. However, recurrent introductions and repeated shuffling of populations may have blurred some of the genetic signals left by ancient introductions. Styela plicata is a solitary ascidian distributed worldwide. Although its origin remains unclear, this species is believed to have spread worldwide by travelling on ship's hulls. The goals of this study were to infer the genetic structure and global phylogeography of S. plicata and to look for present-day and historical genetic patterns. Two genetic markers were used: a fragment of the mitochondrial gene Cytochrome Oxidase subunit I (COI) and a fragment of the nuclear gene Adenine Nucleotide Transporter/ADP-ATP Translocase (ANT). A total of 368 individuals for COI and 315 for ANT were sequenced from 17 locations worldwide. The levels of gene diversity were moderate for COI to high for ANT. The Mediterranean populations showed the least diversity and allelic richness for both markers, while the Indian, Atlantic and Pacific Oceans had the highest gene and nucleotide diversities. Network and phylogenetic analyses with COI and ANT revealed two groups of alleles separated by 15 and 4 mutational steps, respectively. The existence of different lineages suggested an ancient population split. However, the geographic distributions of these groups did not show any consistent pattern, indicating different phylogeographic histories for each gene. Genetic divergence was significant for many population-pairs irrespective of the geographic distance among them. Stochastic introduction events are reflected in the uneven distribution of COI and ANT allele frequencies and groups among many populations. Our results confirmed that S. plicata has been present in all studied oceans for a long time, and that recurrent colonization events and occasional shuffling among populations have determined the actual genetic structure of this species.

Societat civil global és un concepte contestat utilitzat des de diferents aproximacions per a descriure una realitat global. El working paper assenyala la utilitat d’una aproximació de societat civil global per analitzar les potencialitats de l’esfera d’abordar els reptes globals del món d’avui. D’acord amb aquesta aproximació la societat civil global és una àrea global complexa de conflicte i contestació, una àrea que ofereix un lloc i uns valors per a reconsiderar el món de diferents maneres, incloent les visions dels marginats de la societat civil. Per una millor comprensió del concepte i dels debats actuals, el paper repassa les concepcions històriques de societat civil des de la Il·lustració fins avui i el context en el qual el concepte adquireix un nou significat i incorpora l’aspecte global. El paper és la fase inicial d’una futura recerca sobre les potencialitats de la societat civil global per a influir i modelar l’estructura del sistema internacional.

Global warming mitigation has recently become a priority worldwide. A large body of literature dealing with energy related problems has focused on reducing greenhouse gases emissions at an engineering scale. In contrast, the minimization of climate change at a wider macroeconomic level has so far received much less attention. We investigate here the issue of how to mitigate global warming by performing changes in an economy. To this end, we make use of a systematic tool that combines three methods: linear programming, environmentally extended input output models, and life cycle assessment principles. The problem of identifying key economic sectors that contribute significantly to global warming is posed in mathematical terms as a bi criteria linear program that seeks to optimize simultaneously the total economic output and the total life cycle CO2 emissions. We have applied this approach to the European Union economy, finding that significant reductions in global warming potential can be attained by regulating specific economic sectors. Our tool is intended to aid policymakers in the design of more effective public policies for achieving the environmental and economic targets sought.

We address the question of what determines entrepreneurship in developing countries. In particular, because of the influence that this may have on the design of entrepreneurship policies, our main concern is whether the determinants of entrepreneurship are the same and/or have the same impact in developed and developing countries. To this end, we discuss the arguments put forward in the literature in support of the existence of differences in the determinants of entrepreneurship between developed and developing countries. We also analyse the results found in empirical studies on the determinants of formal firm entry (following the World Bank, our proxy of entrepreneurship) in developing countries and compare these results with those typically found in developed countries. Our main conclusion is that policy makers in developing economies should be careful when using evidence from developed countries to design entrepreneurship-promoting policies. Key words: entrepreneurship, developing countries. JEL: O1; O12; L26; M13
