El objetivo de esta tesis doctoral es presentar el marco completo que abarca la real boda de María Luisa de Orleáns y Carlos II, desde que tuvo lugar la ceremonia por poderes el 31 de agosto de 1679 en Fontainebleau hasta la real entrada en Madrid el 11 de enero de 1681, basado en el estudio y edición de las fuentes que relatan el acontecimiento y los elementos teatrales y parateatrales que subyacen de dicho estudio, con la idea de demostrar la funcionalidad de la fiesta y la literatura en la celebración nupcial. La presente tesis se inscribe en la línea de investigación del trabajo que presentamos para la obtención del DEA, titulado Boda de Felipe IV y Mariana de Austria (1649) Relaciones de sucesos y poesía celebrativa, cuya elaboración abrió el campo de investigación de la tesis que ahora presentamos en tres direcciones: la primera de ellas, el estudio de las relaciones de sucesos cortesanas, fuente histórica principal. La segunda, la literatura española de las postrimerías del Barroco y la tercera, la figura de la reina María Luisa de Orleáns. Durante la primera parte de nuestra investigación nos hemos encontrado con muchas fuentes de información y a priori con un tema trabajado desde diferentes ángulos. De manera que la originalidad de nuestra tesis radica, por un lado, en la focalización del tema, enmarcándolo en el acontecimiento de la real boda, tomando para ello fuentes de información tanto histórica, como literaria; y por otro lado, la perspectiva ofrecida desde el punto de vista y el sentir de la reina María Luisa, que es lo que da sentido a la literatura que enmarca la boda de los reyes. El planteamiento y el contenido de esta tesis se justifican por la necesidad de ilustrar el evento regio bajo una luz que aúne la ingente información que nos ofrecen las fuentes históricas y literarias, y presentar de manera sinérgica los aspectos históricos, literarios y filológicos, demostrando con ello la indisolubilidad de estos campos de investigación para una mayor aproximación a la verdad histórica...

This paper presents the results of a research that aimed at identifying optimal performance standards of Brazilian public and philanthropic hospitals. In order to carry out the analysis, a model based on Data Envelopment Analysis (DEA) was developed. We collected financial data from hospitals’ financial statements available on the internet, as well as operational data from the Information Technology Department of the Brazilian Public Health Care System – SUS (DATASUS). Data from 18 hospitals from 2007 to 2011 were analyzed. Our DEA model used both operational and financial indicators (variables). In order to develop this model, two indicators were considered inputs: Values (in Brazilian Reais) of Fixed Assets and Planned Capacity. On the other hand, the following indicators were considered outputs: Net Margin, Return on Assets and Institutional Mortality Rate. As regards the proposed model, there were five hospitals with optimal performance and four hospitals were considered inefficient, upon the analysis of the variables, considering the analyzed period. Analysis of the weights indicated the most relevant variables for determining efficiency and scale variable values, which is an important tool to aid the decision-making by hospital managers. Finally, the scale variables determined the returns on production, indicating that 14 hospitals work with scale diseconomies. This may indicate inefficiency in the resource management of the Brazilian public health-care system, by analyzing this set of proposed variables.

This paper reports on a complex environmental approach to addressing 'wicked' health promotion problems devised to inform policy for enhancing food security and physical activity among Māori, Pacific and low-income people in New Zealand. This multi-phase research utilized literature reviews, focus groups, stakeholder workshops and key informant interviews. Participants included members of affected communities, policy-makers and academics. Results suggest that food security and physical activity 'emerge' from complex systems. Key areas for intervention include availability of money within households; the cost of food; improvements in urban design and culturally specific physical activity programmes. Seventeen prioritized intervention areas were explored in-depth and recommendations for action identified. These include healthy food subsidies, increasing the statutory minimum wage rate and enhancing open space and connectivity in communities. This approach has moved away from seeking individual solutions to complex social problems. In doing so, it has enabled the mapping of the relevant systems and the identification of a range of interventions while taking account of the views of affected communities and the concerns of policy-makers. The complex environmental approach used in this research provides a method to identify how to intervene in complex systems that may be relevant to other 'wicked' health promotion problems.

OBJECTIVE: To determine the average price difference between foods and beverages in remote Indigenous community stores and capital city supermarkets and explore differences across products.

METHODS: A cross-sectional survey compared prices derived from point-of-sale data in 20 remote Northern Territory stores with supermarkets in capital cities of the Northern Territory and South Australia for groceries commonly purchased in remote stores. Average price differences for products, supply categories and food groups were examined.

RESULTS: The 443 products examined represented 63% of food and beverage expenditure in remote stores. Remote products were, on average, 60% and 68% more expensive than advertised prices for Darwin and Adelaide supermarkets, respectively. The average price difference for fresh products was half that of packaged groceries for Darwin supermarkets and more than 50% for food groups that contributed most to purchasing.

CONCLUSIONS: Strategies employed by manufacturers and supermarkets, such as promotional pricing, and supermarkets' generic products lead to lower prices. These opportunities are not equally available to remote customers and are a major driver of price disparity.

IMPLICATIONS: Food affordability for already disadvantaged residents of remote communities could be improved by policies targeted at manufacturers, wholesalers and/or major supermarket chains.

BACKGROUND: Avian influenza viruses (AIVs) are found worldwide in numerous bird species, causing significant disease in gallinaceous poultry and occasionally other species. Surveillance of wild bird reservoirs provides an opportunity to add to the understanding of the epidemiology of AIVs. METHODS: This study examined key findings from the National Avian Influenza Wild Bird Surveillance Program over a 5-year period (July 2007-June 2012), the main source of information on AIVs circulating in Australia. RESULTS: The overall proportion of birds that tested positive for influenza A via PCR was 1.9 ± 0.1%, with evidence of widespread exposure of Australian wild birds to most low pathogenic avian influenza (LPAI) subtypes (H1-13, H16). LPAI H5 subtypes were found to be dominant and widespread during this 5-year period. CONCLUSION: Given Australia's isolation, both geographically and ecologically, it is important for Australia not to assume that the epidemiology of AIV from other geographic regions applies here. Despite all previous highly pathogenic avian influenza outbreaks in Australian poultry being attributed to H7 subtypes, widespread detection of H5 subtypes in wild birds may represent an ongoing risk to the Australian poultry industry.

Substantial structural reform has occurred in the water and wastewater sectors of Australia's major urban centers over the past two decades. This reform has involved the corporatization of government assets and some vertical and horizontal separation. This paper analyses the performance of these sectors since the mid 1990s. In particular, it uses Malmquist Data Envelopment Analysis (DEA) to determine the different levels of productivity and efficiency improvement over this period. The results point to modest, but positive productivity gains in the larger urban centers, independent of industry structure. Further, it highlights the need to consider exogenous factors that can influence productivity outcomes in an industry generally associated with monopoly characteristics and dependent on water sources that are, to varying extents, unpredictable and uncontrollable.

Protein purification plays a crucial role in biotechnology and biomanufacturing, where downstream unit operations account for 40%-80% of the overall costs. To overcome this issue, companies strive to simplify the separation process by reducing the number of steps and replacing expensive separation devices. In this context, commercially available polybutylene terephthalate (PBT) melt-blown nonwoven membranes have been developed as a novel disposable membrane chromatography support. The PBT nonwoven membrane is able to capture products and reduce contaminants by ion exchange chromatography. The PBT nonwoven membrane was modified by grafting a poly(glycidyl methacrylate) (GMA) layer by either photo-induced graft polymerization or heat induced graft polymerization. The epoxy groups of GMA monomer were subsequently converted into cation and anion exchangers by reaction with either sulfonic acid groups or diethylamine (DEA), respectively. Several parameters of the procedure were studied, especially the effect of (i) % weight gain and (ii) ligand density on the static protein binding capacity. Bovine Serum Albumin (BSA) and human Immunoglobulin G (hIgG) were utilized as model proteins in the anion and cation exchange studies. The performance of ion exchange PBT nonwovens by HIG was evaluated under flow conditions. The anion- and cation- exchange HIG PBT nonwovens were evaluated for their ability to selectively adsorb and elute BSA or hIgG from a mixture of proteins. Cation exchange nonwovens were not able to reach a good protein separation, whereas anion exchange HIG nonwovens were able to absorb and elute BSA with very high value of purity and yield, in only one step of purification.

To compare the accuracy of different forecasting approaches an error measure is required. Many error measures have been proposed in the literature, however in practice there are some situations where different measures yield different decisions on forecasting approach selection and there is no agreement on which approach should be used. Generally forecasting measures represent ratios or percentages providing an overall image of how well fitted the forecasting technique is to the observations. This paper proposes a multiplicative Data Envelopment Analysis (DEA) model in order to rank several forecasting techniques. We demonstrate the proposed model by applying it to the set of yearly time series of the M3 competition. The usefulness of the proposed approach has been tested using the M3-competition where five error measures have been applied in and aggregated to a single DEA score.

This thesis has its origin in a previous work: “The Catalan theatrical life in the magazine ‘El Teatre Català’ (1912-1917)” (DEA, UCM, 2004-2005), focused on the history, description and the indexes of that magazine. Among the historical and literary references ordered there, we chose a figure that would make a monographic work resulting in the present Doctoral Thesis. The choice fell on Avel·lí Artís i Balaguer (1881-1954), whose personality and literary corpus, allow additional possibilities for research. The cultural and literary reach of his life and his work covers a whole historical cycle in Catalan culture and literature, which moves from its contemporary consolidation towards the drama of its temporal dislocation, between the Spanish Civil War and the exile experience. This e historical itinerary is represented by Avel·lí Artís i Balaguer, being a playwright and a publisher. He’s been considered a comedy playwright since his editions bear titles such as “comedy”, “pas comedy”, “sainet” “quadro”, “farce” or “dialogue”, at most we find the word “Drama” once and “tragicomedy” twice, and we can find all this, in a series of texts for the representation ranging from 1909 to 1938. Secondly, as a professional fully involved in printing and publishing, thereby covering since its first steps as a compositor in the late nineties of the 19th century until his activity as a crucial character for magazines and other publishing projects, from the first decade of the 20th century until the last year of his Mexican exile...
