Tourism, nightlife and planning: challenges and opportunities for community liveability in La Barceloneta

In La Barceloneta, one of the beachfront quarters of the city of Barcelona, the rapid expansion of mainly illegal short-term rental apartments for tourists and noise problems related to alcohol-fuelled nightlife consumption, are challenging community liveability and peaceful urban coexistence between different social groups. Similar to other cases worldwide, the rapid expansion of touristification on the urban and socio-economic fabric of the city has become an increasing source of dispute and residents' contestation. By taking a diachronical critical review, the first part of this paper examines the role of urban planning developed in La Barceloneta during the period 1950–2016 and how it transformed the area into a leisure-oriented and tourist-oriented quarter. The second part of the paper is based on two years of ethnographic fieldwork that was conducted to capture the range of different voices, stories and discourses produced and reproduced by different actors affected and/or involved in the recent touristification of La Barceloneta. Findings obtained confirm that current urban policy and planning are clearly insufficient to tackle and address negative community-based impacts aforementioned. Hence, the final section highlights the urgent need for the development and implementation of new, community-based urban planning with the aim of ensuring community liveability and peaceful urban coexistence between different social groups in La Barceloneta

This article outlines a collaboration between the Foundation Centre and the Education PGCE department at Durham University to support student teachers on a particular academic writing assignment (the Self Directed Study assignment). This project involved designing online academic writing activities tailored especially to the assignment. These activities made use of excerpts of exemplar student writing as well as the FOCUS corpus, a Foundation Centre initiated database of “good” (2:1 or First) Durham University student writing. The article outlines the challenges for the students with this particular assignment, details of the collaboration, student feedback from the first roll out of the activities as well as future steps in this ongoing project

A Z2\mathbb{Z}_{2}-Topological Index for Free-Fermion Systems in Disordered Media

We use infinite dimensional self--dual $\mathrm{CAR}$ $C^{*}$-algebras to study a $\mathbb{Z}_{2}$-index, which classifies free--fermion systems embedded on $\mathbb{Z}^{d}$-index disordered lattices. Combes-Thomas estimates are pivotal to show that the $\mathbb{Z}_{2}$-index is uniform with respect to the size of the system. We additionally deal with the set of ground states to completely describe the mathematical structure of the underlying system. Furthermore, the weak$^{*}$--topology of the set of linear functionals is used to analyze paths connecting different sets of ground states.Comment: 38 pages, typos corrected, references adde

Phisically based modelling of induction lamps: aplication to the improvement of energy efficiency in the lighting system of a University building. Poster

To manage efforts in energy efficiency, the Polytechnic University of Cartagena (UPCT) decided in 2003 to develop an ambitious project to reduce energy use intensity and costs during the period 2003-2008. To accomplish this objective in lighting end-use demand -one of the two main electrical uses together with space cooling/heating-, the UPCT joins, in July 2002, the U.E. GreenLight program as a partner. This paper describes the University experience in the second year (2003/04) of partnership in this UE initiative. The objectives were: to manage the demand, to improve the quality of lighting, working and environmental conditions, and reduce significantly energy and O&M expenses. Basically, the work developed in this year is focused in the change of conventional High Intensity Discharge (HID) lighting systems in classrooms (2000 m2) through the evaluation of advantages and drawbacks of different alternatives. The most promising one, the change to a new technology -165W induction lamps-, will be analyzed in detail in the paper

Mycobacterium tuberculosis ecology in Venezuela: epidemiologic correlates of common spoligotypes and a large clonal cluster defined by MIRU-VNTR-24

<p>Abstract</p> <p>Background</p> <p>Tuberculosis remains an endemic public health problem, but the ecology of the TB strains prevalent, and their transmission, can vary by country and by region. We sought to investigate the prevalence of <it>Mycobacterium tuberculosis </it>strains in different regions of Venezuela. A previous study identified the most prevalent strains in Venezuela but did not show geographical distribution nor identify clonal genotypes. To better understand local strain ecology, we used spoligotyping to analyze 1298 <it>M. tuberculosis </it>strains isolated in Venezuela from 1997 to 2006, predominantly from two large urban centers and two geographically distinct indigenous areas, and then studied a subgroup with MIRU-VNTR 24 loci.</p> <p>Results</p> <p>The distribution of spoligotype families is similar to that previously reported for Venezuela and other South American countries: LAM 53%, T 10%, Haarlem 5%, S 1.9%, X 1.2%, Beijing 0.4%, and EAI 0.2%. The six most common shared types (SIT's 17, 93, 605, 42, 53, 20) accounted for 49% of the isolates and were the most common in almost all regions, but only a minority were clustered by MIRU-VNTR 24. One exception was the third most frequent overall, SIT 605, which is the most common spoligotype in the state of Carabobo but infrequent in other regions. MIRU-VNTR homogeneity suggests it is a clonal group of strains and was named the "Carabobo" genotype. Epidemiologic comparisons showed that patients with SIT 17 were younger and more likely to have had specimens positive for Acid Fast Bacilli on microscopy, and patients with SIT 53 were older and more commonly smear negative. Female TB patients tended to be younger than male patients. Patients from the high incidence, indigenous population in Delta Amacuro state were younger and had a nearly equal male:female distribution.</p> <p>Conclusion</p> <p>Six SIT's cause nearly half of the cases of tuberculosis in Venezuela and dominate in nearly all regions. Strains with SIT 17, the most common pattern overall may be more actively transmitted and SIT 53 strains may be less virulent and associated with reactivation of past infections in older patients. In contrast to other common spoligotypes, strains with SIT 605 form a clonal group centered in the state of Carabobo.</p

Characterization of the genetic diversity of Mycobacterium tuberculosis in São Paulo city, Brazil

<p>Abstract</p> <p>Background</p> <p>Tuberculosis is a major health problem in São Paulo, Brazil, which is the most populous and one of the most cosmopolitan cities in South America. To characterize the genetic diversity of <it>Mycobacterium tuberculosis </it>in the population of this city, the genotyping techniques of spoligotyping and MIRU were applied to 93 isolates collected in two consecutive years from 93 different tuberculosis patients residing in São Paulo city and attending the Clemente Ferreira Institute (the reference clinic for the treatment of tuberculosis).</p> <p>Findings</p> <p>Spoligotyping generated 53 different spoligotype patterns. Fifty-one isolates (54.8%) were grouped into 13 spoligotyping clusters. Seventy- two strains (77.4%) showed spoligotypes described in the international databases (SpolDB4, SITVIT), and 21 (22.6%) showed unidentified patterns. The most frequent spoligotype families were Latin American Mediterranean (LAM) (26 isolates), followed by the T family (24 isolates) and Haarlem (H) (11 isolates), which together accounted for 65.4% of all the isolates. These three families represent the major genotypes found in Africa, Central America, South America and Europe. Six Spoligo-International-types (designated SITs by the database) comprised 51.8% (37/72) of all the identified spoligotypes (SIT53, SIT50, SIT42, SIT60, SIT17 and SIT1). Other SITs found in this study indicated the great genetic diversity of <it>M. tuberculosis</it>, reflecting the remarkable ethnic diversity of São Paulo city inhabitants. The MIRU technique was more discriminatory and did not identify any genetic clusters with 100% similarity among the 93 isolates. The allelic analysis showed that MIRU loci 26, 40, 23 and 10 were the most discriminatory. When MIRU and spoligotyping techniques were combined, all isolates grouped in the 13 spoligotyping clusters were separated.</p> <p>Conclusions</p> <p>Our data indicated the genomic stability of over 50% of spoligotypes identified in São Paulo and the great genetic diversity of <it>M. tuberculosis </it>isolates in the remaining SITs, reflecting the large ethnic mix of the São Paulo city inhabitants. The results also indicated that in this city, <it>M. tuberculosis </it>isolates acquired drug resistance independently of genotype and that resistance was more dependent on the selective pressure of treatment failure and the environmental circumstances of patients.</p

Caracterización clínicoepidemiológica de pacientes con enfermedades reumáticas de inicio juvenil en Paraguay (2011 – 2015)

Objective: Describe the frequency of juvenile onset rheumatologic inflammatory diseases (JIR ) in level III and IV complexity level hospitals in a quinquennium. Methods: Multicentric, descriptive and retrospective study, using CI E-10 coding of hospitals’ files in Asunción and Central Department. Results: Four hospitalary records were included. 382 patients followed inclusion criteria. Sex ratio (M:F) of the population was 1:1,6, with an average age at captation of 11.6 years (SD±4.5). Kawsaki’s disease group has an average age of 5.4 years (SD±3.7) and patients with systemic lupus erythematosus (SLE) were presented with 13.1 years on average (SD±3.9). The 68,6% of patients were found through follow up specialized consults. Idiopathic juvenile arthritis was the most frequently diagnosed disease (n=167 cases, 43,7% of the total), followed by SLE (n=130, 34,0%). Most of the cases (n=290, 75,9%) were patients from (place of birth) Asuncion or Central Department. Conclusion: The spectrum of JIR diseases is broad with variable distribution in each included hospital. This study orients to know the burden of disease from JIR diseases in Paraguay.Objetivo: Describir la frecuencia de las enfermedades reumatológicas inflamatorias de inicio juvenil (RI J) en hospitales de nivel de complejidad III y IV en un quinquenio.

El grupo de pacientes con Enfermedad de Kawasaki tenían edad promedio de 5.4 años (± 3.7 DE) y los pacientes con Lupus Eritematoso Sistémico (LES) se presentaron con 13.1 años (± 3.9 DE). El 68,6% de los pacientes fueron captados por consulta especializada de seguimiento. La artritis idiopática juvenil fue la enfermedad RIJ más frecuentemente diagnosticada (n=167 casos, 43,7% del total), seguida por el LES (n=130, 34,0%). La mayoría de los casos (75.9%, n=290) eran pacientes procedentes (al nacimiento) de Asunción o del departamento central. Conclusión: El espectro de las enfermedades RI J es amplio con distribución variable según los hospitales incluidos. Este estudio orienta a conocer la “carga de enfermedad” por enfermedades RI J en Paraguay

Prioritizing persons deprived of liberty in global guidelines for tuberculosis preventive treatment

Persons deprived of liberty (PDLs) are disproportionately impacted by tuberculosis, with high incidence rates and often limited access to diagnostics, treatment, and preventive measures. The World Health Organization (WHO) expanded its recommendations for tuberculosis preventive treatment (TPT) to many high-risk populations, but their guidance does not include PDL, and most low- and middle-income countries do not routinely provide edforthoseusedthroughoutthetext TPT in prisons. :Pleaseverifythatallentriesarecorrectlyabbreviated: Recent studies demonstrate high acceptability and completion rates of short-course TPT regimens in jails and prisons; costs of these regimens have been markedly reduced through international agreements, making this an opportune for further expanding their use. We argue that PDL should be a priority group for TPT in national guidelines and discuss implementation considerations and resource needs for TPT programs in carceral facilities. Scaling access to TPT for PDL is important for reducing disease and transmission in this population; it is also critical to advancing an equitable response to tuberculosis
