El Forment a la Barcelona baixmedieval: preus, mesures i fiscalitat (1283-1345)

A través de l'anàlisi de dos sèries de diferents llibres de comptabilitat de Barcelona, els procedents de la gestió dels molins reals i els redactats per una institució eclesiàstica, la Pia Almoina, vam començar a estudiar el mercat del blat a Barcelona durant l'edat mitjana. Hem analitzat anteriorment el valor de les mesures a Barcelona i, per poder qualificar el preu real del pa, també hem estudiat els diferents processos industrials per fer pa de blat. Després, hem analitzat el conjunt d'impostos que pesaven sobre la comercialització de cereals. A través de l'estudi de l'evolució dels preus, hem tractat de fer una primera aproximació de la primera etapa de la crisi baixmedieval, concretament entre 1283 i 1345, tenint en compte els contrastos amb els treballs ja coneguts sobre la base de les fonts on la noció de quantitat no va ser considerada. Finalment, hem comparat els nostres resultats amb alguns treballs referents a la Corona d'Aragó i el món mediterrani, a fi d'obtenir una idea més precisa de la cronologia de les crisis de subsistència

Ordinacions, privilegis i oficis: la regulació de l'art de l'especieria (s. XIV-XV)

L’estudi de l’evolució de la regulació de l’art de l’especieria o apotecaria a Barcelona permet copsar com les arts i els oficis no solament s’aprofitaren en benefici propi de la cessió del "ius statuendi" al govern municipal, sinó que, quan ho van considerar convenient, van acudir al rei per tal que consolidés per via de privilegi la seva posició de força en el seu camp professional

Les Ordinacions de mercaderies encamerades o falsificades: evolució del control municipal sobre la qualitat de les espècies i les drogues (segles XIV-XV)

Aproximació al funcionament de la mostassafia barcelonina medieval, i a la creació d’un dret municipal encarregat de regular la vida ciutadana. Aquesta aproximació es fa a partir d’un aspecte relativament simple: el control de la qualitat de les espècies i les drogues. L’anàlisi de les ordinacions de mercaderies encamerades serveix per veure com els consellers aprofitaren la creació de la figura del mostassaf i l’establiment de les seves àmplies atribucions normatives per controlar l’activitat mercantil barcelonina

Les Compravendes al detall i a crèdit en el món artesà: El cas dels especiers i els candelers: El cas dels especiers i els candelers

Estudi de com el crèdit va tenir un paper molt important en les compravendes al detall en els gremis dels especiers (o apotecaris) i cerers a la Barcelona baixmedieval. Es pretén extrapolar les conclusions per aquests dos col•lectius a altres grups socioprofessionals similars. Es parteix de la teoria que aquest paper del crèdit va ser ben diferent que el desenvolupat en les pràctiques mercantils, bancàries i rendistes

Mount Carmel in the Commune: Promoting the Holy Land in Central Italy in the 13th and 14th Centuries

The Carmelite friars were the last of the major mendicant orders to be established in Italy. Originally an eremitical order, they arrived from the Holy Land in the 1240s, decades after other mendicant orders, such as the Franciscans and Dominicans, had constructed churches and cultivated patrons in the burgeoning urban centers of central Italy. In a religious market already saturated with friars, the Carmelites distinguished themselves by promoting their Holy Land provenance, eremitical values, and by developing an institutional history claiming to be descendants of the Old Testament prophet Elijah. By the end of the 13th century the order had constructed thriving churches and convents and leveraged itself into a prominent position in the religious community. My dissertation analyzes these early Carmelite churches and convents, as well as the friars’ interactions with patrons, civic governments, and the urban space they occupied. Through three primary case studies – the churches and convents of Pisa, Siena and Florence – I examine the Carmelites’ approach to art, architecture, and urban space as the order transformed its mission from one of solitary prayer to one of active ministry.

My central questions are these: To what degree did the Carmelites’ Holy Land provenance inform the art and architecture they created for their central Italian churches? And to what degree was their visual culture instead a reflection of the mendicant norms of the time?

I have sought to analyze the Carmelites at the institutional level, to determine how the order viewed itself and how it wanted its legacy to develop. I then seek to determine how and if the institutional model was utilized in the artistic and architectural production of the individual convents. The understanding of Carmelite art as a promotional tool for the identity of the order is not a new one, however my work is the first to consider deeply the order’s architectural aspirations. I also consider the order’s relationships with its de facto founding saint, the prophet Elijah, and its patron, the Virgin Mary, in a more comprehensive manner that situates the resultant visual culture into the contemporary theological and historical contexts.

Socio-economic conditions of the pond owners of Demra, Dhaka

On the basis of fish culture status 96 ponds of the study area were classified into 4 categories like wild stock (27%), extensive culture (24%), improved extensive culture (33%) and semi-intensive culture (16%). Percentage of small, medium and large ponds were 38, 44, and 18 respectively whereas education levels below SSC, below Bachelor and above were 43, 38 and 19 respectively and single owners belonged to 54% of the ponds. Per hectare yields of extensive, improved extensive and semi-intensive categories of culture were 1.3, 2.12 and 4.0 metric tons respectively and their net return were 46, 63 and 92 thousand taka respectively. Considering the problems of fish culture, multiple ownership was found to be the most important one.

The new blockbuster film sequel : changing cultural and economic conditions within the film industry

Film sequels are a pervasive part of film consumption practices and have become an important part of the decision making process for Hollywood studios and producers. This thesis indicates that sequels are not homogenous groups of films, as they are often considered, but offer a variety of story construction and utilize a variety of production methods. Three types of blockbuster sequel sets are identified and discussed in this thesis. The Traditional Blockbuster Sequel Set, as exemplified by Back to the Future (1985, 1989, 1990) films, is the most conventional type of sequel set and capitalizes on the winning formula of the first film in the franchise. The MultiMedia Sequel Set, such as The Matrix (1999,2003) trilogy, allows the user/viewer to experience and consume the story as well as the world of the film through many different media. The Lord a/ the Rings (2001, 2002, 2003) set of films is an illustration of The Saga Sequel Set where plot lines are continuous over the entire franchise thus allowing the viewer to see the entire set as a unified work. The thesis also demonstrates how the blockbuster sequel sets, such as the Pirates a/ the Caribbean (2003, 2006, 2007) franchise, restructure the production process of the Hollywood film industry.

Changes of traditional farming systems and their effects on land degradation and socio-economic conditions in the Inle Lake region, Myanmar

At many locations in Myanmar, ongoing changes in land use have negative environmental impacts and threaten natural ecosystems at local, regional and national scales. In particular, the watershed area of Inle Lake in eastern Myanmar is strongly affected by the environmental effects of deforestation and soil erosion caused by agricultural intensification and expansion of agricultural land, which are exacerbated by the increasing population pressure and the growing number of tourists. This thesis, therefore, focuses on land use changes in traditional farming systems and their effects on socio-economic and biophysical factors to improve our understanding of sustainable natural resource management of this wetland ecosystem. The main objectives of this research were to: (1) assess the noticeable land transformations in space and time, (2) identify the typical farming systems as well as the divergent livelihood strategies, and finally, (3) estimate soil erosion risk in the different agro-ecological zones surrounding the Inle Lake watershed area. GIS and remote sensing techniques allowed to identify the dynamic land use and land cover changes (LUCC) during the past 40 years based on historical Corona images (1968) and Landsat images (1989, 2000 and 2009). In this study, 12 land cover classes were identified and a supervised classification was used for the Landsat datasets, whereas a visual interpretation approach was conducted for the Corona images. Within the past 40 years, the main landscape transformation processes were deforestation (- 49%), urbanization (+ 203%), agricultural expansion (+ 34%) with a notably increase of floating gardens (+ 390%), land abandonment (+ 167%), and marshlands losses in wetland area (- 83%) and water bodies (- 16%). The main driving forces of LUCC appeared to be high population growth, urbanization and settlements, a lack of sustainable land use and environmental management policies, wide-spread rural poverty, an open market economy and changes in market prices and access. To identify the diverse livelihood strategies in the Inle Lake watershed area and the diversity of income generating activities, household surveys were conducted (total: 301 households) using a stratified random sampling design in three different agro-ecological zones: floating gardens (FG), lowland cultivation (LL) and upland cultivation (UP). A cluster and discriminant analysis revealed that livelihood strategies and socio-economic situations of local communities differed significantly in the different zones. For all three zones, different livelihood strategies were identified which differed mainly in the amount of on-farm and off-farm income, and the level of income diversification. The gross margin for each household from agricultural production in the floating garden, lowland and upland cultivation was US$ 2108, 892 and 619 ha-1 respectively. Among the typical farming systems in these zones, tomato (Lycopersicon esculentum L.) plantation in the floating gardens yielded the highest net benefits, but caused negative environmental impacts given the overuse of inorganic fertilizers and pesticides. The Revised Universal Soil Loss Equation (RUSLE) and spatial analysis within GIS were applied to estimate soil erosion risk in the different agricultural zones and for the main cropping systems of the study region. The results revealed that the average soil losses in year 1989, 2000 and 2009 amounted to 20, 10 and 26 t ha-1, respectively and barren land along the steep slopes had the highest soil erosion risk with 85% of the total soil losses in the study area. Yearly fluctuations were mainly caused by changes in the amount of annual precipitation and the dynamics of LUCC such as deforestation and agriculture extension with inappropriate land use and unsustainable cropping systems. Among the typical cropping systems, upland rainfed rice (Oryza sativa L.) cultivation had the highest rate of soil erosion (20 t ha-1yr-1) followed by sebesten (Cordia dichotoma) and turmeric (Curcuma longa) plantation in the UP zone. This study indicated that the hotspot region of soil erosion risk were upland mountain areas, especially in the western part of the Inle lake. Soil conservation practices are thus urgently needed to control soil erosion and lake sedimentation and to conserve the wetland ecosystem. Most farmers have not yet implemented soil conservation measures to reduce soil erosion impacts such as land degradation, sedimentation and water pollution in Inle Lake, which is partly due to the low economic development and poverty in the region. Key challenges of agriculture in the hilly landscapes can be summarized as follows: fostering the sustainable land use of farming systems for the maintenance of ecosystem services and functions while improving the social and economic well-being of the population, integrated natural resources management policies and increasing the diversification of income opportunities to reduce pressure on forest and natural resources.

A threshold hypothesis of institutional change: collective action in the Italian Alps during the 13th - 19th centuries.

This dissertation is about collective action issues in common property resources. Its focus is the “threshold hypothesis,” which posits the existence of a threshold in group size that drives the process of institutional change. This hypothesis is tested using a six-century dataset concerning the management of the commons by hundreds of communities in the Italian Alps. The analysis seeks to determine the group size threshold and the institutional changes that occur when groups cross this threshold. There are five main findings. First, the number of individuals in villages remained stable for six centuries, despite the population in the region tripling in the same period. Second, the longitudinal analysis of face-to-face assemblies and community size led to the empirical identification of a threshold size that triggered the transition from informal to more formal regimes to manage common property resources. Third, when groups increased in size, gradual organizational changes took place: large groups split into independent subgroups or structured interactions into multiple layers while maintaining a single formal organization. Fourth, resource heterogeneity seemed to have had no significant impact on various institutional characteristics. Fifth, social heterogeneity showed statistically significant impacts, especially on institutional complexity, consensus, and the relative importance of governance rules versus resource management rules. Overall, the empirical evidence from this research supports the “threshold hypothesis.” These findings shed light on the rationale of institutional change in common property regimes, and clarify the mechanisms of collective action in traditional societies. Further research may generalize these conclusions to other domains of collective action and to present-day applications.
