L'impacte de la mort del rei Martí l'Humà a la Ciutat de Barcelona: conseqüències al municipi i a la vida quotidiana a partir del llibre de clavaria del Consell de Cent del 1410

Treballs Finals del Màster de Cultures Medievals, Facultat de Filologia, Universitat de Barcelona, Curs: 2013-2014, Tutor: Prim Bertran RoigéEl tema en el que vull desenvolupar la meva recerca són les estructures polítiques medievals, centrant-me en una institució municipal en particular: el Consell de Cent de la ciutat de Barcelona a principis del segle XV. Per realitzar aquesta tasca he cercat en els arxius que aquest organisme va produir, utilitzant-los com la font d‟estudi. L‟elecció de la cronologia a investigar per tant, ha estat la Baixa Edat Mitjana, ja que el Consell fou establert al segle XIII i va anar adquirint la seva forma característica durant el XIV i el XV, mantenint la seva força fins el segle XVIII, moment en el que va ésser dissolt, com a conseqüència de l‟aplicació del Decret de Nova Planta (1716)

Les galeres catalanes a les armades pontifícies en època del Cisma d’Occident. Edició i estudi de l’armada de Benet XIII a Niça (Perpinyà) del 1415

[cat] Aquesta tesi doctoral té com a objectiu l’estudi de la participació de la Corona d’Aragó a les armades pontifícies durant el Cisma d’Occident i, en especial, la contribució de les galeres catalanes. Les relacions entre el papat i la Corona tingueren una dimensió que anava més enllà de la pròpia monarquia. Tant el rei com nombrosos nobles, clergat, ciutats i ciutadans honrats participaren en aquestes campanyes navals a canvi de privilegis i beneficis polítics i econòmics. L’eix cronològic de les flotes analitzades va des del 1370, poc abans de que s’originés el Cisma, fins a les acaballes d’aquest, amb l’esquadra de 1415. La tesi es tanca amb un apèndix documental amb la transcripció dels comptes de l’organització d’aquesta última armada.[eng] This thesis aims to study the participation of the Crown of Aragon in the papal fleets during the Western Schism and, especially, the contribution of the Catalan galleys. The period of the fleets analyzed here starts in 1370, shortly before the beginning of the schismatic episode, and ends with the papal fleet of 1415

Diminishing benefits of urban living for children and adolescents’ growth and development

Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods: We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5-19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI &lt;18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For school-aged children and adolescents, we report thinness (BMI &lt;2 SD below the median of the WHO growth reference) and obesity (BMI &gt;2 SD above the median). Findings: From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation: The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesity.
