This paper proposes an alternative input-output based spatial-structural decomposition analysis to elucidate the role of domestic-regional heterogeneity and interregional spillover effects in determining China's regional CO2 emission growth. Our empirical results based on the 2007 and 2010 Chinese interregional input-output tables show that the changes in most regions' final demand scale, final expenditure structure and export scale give positive spatial spillover effects on other regions' CO2 emission growth, the changes in most regions' consumption and export preference help the reduction of other regions' CO2 emissions, the changes in production technology, and investment preference may give positive or negative impacts on other region's CO2 emission growth through domestic supply chains. For some regions, the aggregate spillover effect from other regions may be larger than the intra-regional effect in determining regional emission growth. All these facts can significantly help better and deeper understanding on the driving forces of China's regional CO2 emission growth, thus can enrich the policy implication concerning a narrow definition of "carbon leakage" through domestic-interregional trade, and relevant political consensus about the responsibility sharing between developed and developing regions inside China.

Mobile activity recognition focuses on inferring the current activities of a mobile user by leveraging the sensory data that is available on today’s smart phones. The state of the art in mobile activity recognition uses traditional classification learning techniques. Thus, the learning process typically involves: i) collection of labelled sensory data that is transferred and collated in a centralised repository; ii) model building where the classification model is trained and tested using the collected data; iii) a model deployment stage where the learnt model is deployed on-board a mobile device for identifying activities based on new sensory data. In this paper, we demonstrate the Mobile Activity Recognition System (MARS) where for the first time the model is built and continuously updated on-board the mobile device itself using data stream mining. The advantages of the on-board approach are that it allows model personalisation and increased privacy as the data is not sent to any external site. Furthermore, when the user or its activity profile changes MARS enables promptly adaptation. MARS has been implemented on the Android platform to demonstrate that it can achieve accurate mobile activity recognition. Moreover, we can show in practise that MARS quickly adapts to user profile changes while at the same time being scalable and efficient in terms of consumption of the device resources.

Location-based services (LBS) highly rely on the location of the mobile user in order to provide the service tailored to that location. This location is calculated differently depending on the technology available in the used mobile device. No matter which technology is used, the location will never be calculated 100% correctly; instead there will always be a margin of error generated during the calculation, which is referred to as positional accuracy. This research has reviewed the eight most common positioning technologies available in the major current smart-phones and assessed their positional accuracy with respect to its usage by LBS applications. Given the vast majority of these applications, this research classified them into thirteen categories, and these categories were also classified depending on their level criticality as low, medium, or high critical, and whether they function indoor or outdoor. The accuracies of different positioning technologies are compared to these two criteria. Low critical outdoor and high critical indoor applications were found technologically covered; high and medium critical outdoor ones weren?t fully resolved. Finally three potential solutions are suggested to be implemented in future smartphones to resolve this technological gap: Real-Time Kinematics Global Positioning System (RTK GPS), terrestrial transmitters, and combination of Wireless Sensors Network and Radio Frequency Identification (WSN-RFID).

La arquitectura china ha experimentado grandes cambios a lo largo de un extenso proceso histórico. El hito de mayor importancia es el que da paso al denominado Tiempo Moderno, periodo en el cual irrumpe por vez primera en China la arquitectura occidental, que comienza a tener una influencia muy activa y significativa sobre los rasgos y la identidad de la arquitectura tradicional china, hasta ese momento el único estilo o forma de hacer –muy diferente, en cuanto a su concepción y fisonomía, de los planteamientos occidentales- que había sobrevivido sin desvíos significativos, configurando un panorama milenario bastante homogéneo en los aspectos técnicos y artísticos en el desarrollo de esa arquitectura. Por un cúmulo de complejas razones, la mayor parte de la arquitectura china del periodo feudal -es decir el que forman todos los años anteriores a 1849- ha desaparecido. Sin embargo, desde la fecha indicada hasta la Revolución de 1949 (el denominado periodo semicolonial o semifeudal), sí se conservan muchas edificaciones, que fueron mejor construidas y mantenidas luego, destacando por su importancia en ese sentido las iglesias cristianas. Dichos templos representan cronológicamente, no sólo la primera irrupción de la arquitectura clásica occidental en China, sino el inicio de un proceso de modernización de la profundamente enraizada y, en buena medida, estancada arquitectura vernácula, combinando técnicas y estilos de ambos planteamientos, para dar como resultado originales edificaciones de un singular eclecticismo que caracterizarían buena parte de la arquitectura de dicha etapa semicolonial. En términos generales, últimamente se ha ido prestando cada vez más atención a esta arquitectura de los tiempos modernos, aunque las iglesias cristianas de la provincia de Shaanxi no han sido objeto de estudio específico, a pesar de que su tipología es muy representativa de las construcciones de esta clase en otras regiones del interior de China. La investigación que desarrolla la presente tesis doctoral sale al paso de esa deficiencia, abriendo puertas a la continuación del trabajo referido, extendido a otras zonas o arquitecturas, y, por extensión, a la profundización analítica de la hibridación arquitectónica y cultural entre China y Occidente. Sobre las bases de investigación documental, estudios de campo y dibujo, la tesis plantea un estudio aclaratorio de los rasgos y raíces de la arquitectura tradicional china, al que sigue otro histórico y tipológico de los templos cristianos en la provincia de Shaanxi, deteniéndose en sus características fundamentales, situación (uso) actual y estado de conservación. Se ha considerado imprescindible añadir al trabajo, como apéndice, un elaborado glosario conceptual ilustrado de términos básicos arquitectónicos y constructivos, en chino, inglés y español. ABSTRACT The Chinese architecture has gone through great changes during the long process of history. The tremendous changing period was the named Modern Times of China when, for the very first time, the western architecture was introduced into China and became to influence majorly on the traditional Chinese architecture. Before that, the traditional Chinese architecture which has its own, yet totally different system from the occidental architecture system was the only architectural style could be found in China. Although, due to many historical, conceptual and architectural characteristic reasons, large amount of the ancient Chinese architecture built in the feudal China was not preserved, there are a lot of buildings of semi-feudal China that was well constructed and conserved. The most important architectural type of the semi-feudal China is the Christian Churches. It was not only the first western architectural form that was brought into and well developed in China, but also was the beginner of the modernization process of Chinese architecture. Because of the deep root of the 2000-year traditional Chinese architecture, all the Christian Churches built in China during the semi-colonial society has a combined style of both the traditional Chinese architecture and the classic western churches. They are a priceless asset of the Chinese architectural history. Recently, more and more attention had been paid on the Chinese Modern Times architecture, however, the Christian Churches in Shaanxi Province, the province which has a unique history with the Christian, but less economically developed have never been researched yet. The Christian Churches of Shaanxi Province reflect the general feature of developing history of the Christian Churches of common inner-land regions in China. The research opens the door to further study on other Christian Churches and related buildings, and also for the further study on the Chinese-western architectural and culture communication. On the base of document research, field survey and mapping, in this thesis, an in-depth study had been done on the general history of the features and roots of the traditional Chinese architecture, the developing history of the Christian Churches of Shaanxi Province and the architectural types, examples, characteristics, present situation and conservation status. By comparing the Christian Churches of the cities in Shaanxi province to the Christian Churches in other more developed cities, and by comparing the Christian Churches in China to the classic western churches, the architectural combination feature of the Christian Churches in China are highlighted. The thesis is a fundamental research on which many further studies about the architectural developing history, characteristics and conservation of the Christian Churches in China could be done. It is considered essential to add to the work, as an appendix, an elaborate conceptual illustrated glossary of architectural and construction terms in Chinese, English and Spanish.

Natural disasters affect hundreds of millions of people worldwide every year. Emergency response efforts depend upon the availability of timely information, such as information concerning the movements of affected populations. The analysis of aggregated and anonymized Call Detail Records (CDR) captured from the mobile phone infrastructure provides new possibilities to characterize human behavior during critical events. In this work, we investigate the viability of using CDR data combined with other sources of information to characterize the floods that occurred in Tabasco, Mexico in 2009. An impact map has been reconstructed using Landsat-7 images to identify the floods. Within this frame, the underlying communication activity signals in the CDR data have been analyzed and compared against rainfall levels extracted from data of the NASA-TRMM project. The variations in the number of active phones connected to each cell tower reveal abnormal activity patterns in the most affected locations during and after the floods that could be used as signatures of the floods - both in terms of infrastructure impact assessment and population information awareness. The epresentativeness of the analysis has been assessed using census data and civil protection records. While a more extensive validation is required, these early results suggest high potential in using cell tower activity information to improve early warning and emergency management mechanisms.

Resumo Em resposta aos desafios atuais de muitas grandes cidades, o contexto institucional e o planeamento territorial formam dimensões para melhorar a governação metropolitana. No quadro das regiões capitais do sudoeste europeu, quais poderão ser as inovações e diferenças nos seus modelos e processos em curso? Este artigo propõe uma investigação aplicada para apresentar a análise da governação metropolitana. Através do método de estudos de caso em perspectiva comparada, vários elementos e entrevistas são ponderados qualitativamente nas regiões de Madrid, Barcelona, Paris e Lisboa. As conclusões encontram uma tendência para o equilíbrio entre os esforços dessas duas dimensões da governação territorial metropolitana, não impedindo registrar os seus diferentes percursos: por exemplo Ile-de-France desenvolveu boas iniciativas em matéria de planeamento, que então pedem alguns ajustamentos no quadro político, enquanto Madrid teve “menos actividade” nos últimos anos, em resultado da sua grande estabilidade institucional. A região de Lisboa permanece talvez numa “posição intermédia”, com uma dinâmica de evolução pouco previsível. Mas de acordo com este argumento, admite-se que os seus processos podem levar a melhorias graduais no sistema de governação, com o seu próprio percurso, implementando acções que devem respeitar, em particular, a geografia do território. Abstract Addressing the running challenges of several greater cities, the institutional mark and regional planning are dimensions for improving metropolitan governance. Regarding the southwest European capital regions, what can be the innovations and differences in their currently processes and models? This paper proposes an applied framework to present the metropolitan governance analysis. Through a comparative case study methodology, various elements and interviews are qualitatively measured in the regions of Madrid, Barcelona, Paris and Lisbon. The conclusions find a tendency to balance between the efforts on those two regional metropolitan governance dimensions, which does not prevent to register their different paths: for example Ile-de-France has developed good initiatives in terms of planning, which then require some adjustments in the political mark, while Madrid had in recent years “less activity”, in result of his institutional stability. The Lisbon region maybe stays in an “intermediate position” with a dynamic evolution that is difficult to predict. But according to that argument, it’s possible to admit that his processes can gradually lead to small improvements in his governance system, with his own path, implementing actions that must respect, in particularly, the geography of the territory.

Os meios de comunicação que atuam em perspectiva regional alcançaram, inegavelmente, maior visibilidade no contexto da globalização. Em se tratando de emissoras regionais de televisão há, em grande parte dos casos, a afiliação a uma rede nacional. Este estudo é sobre uma emissora regional, a TV TEM Bauru, integrante do grupo TV TEM de afiliadas à Rede Globo de Televisão. O trabalho se fundamenta em conceitos de região, espaço, território e local, mídia local e televisão regional. Tem como objetivo compreender as configurações desta TV, no que se refere às suas origens, vínculos corporativos e as condições de ordem tecnológica, de sustentação comercial e de cobertura jornalística, especificamente, a produção e circulação da informação jornalística gerada e difundida nas cidades da região de cobertura do grupo TV TEM. Visa também caracterizar a relação entre o espaço total de programação ocupado pela cabeça-de-rede em nível nacional e aquele destinado a programas jornalísticos produzidos localmente e, dentro destes, o tempo destinado à veiculação de anúncios publicitários em escala regional. Opta-se pelo método de abordagem dialético, dada a complexidade e as contradições do fenômeno investigado. Trata-se de uma investigação qualitativa do tipo estudo de caso, mas que incorpora dados quantitativos, e se baseia em observação e estudo de conteúdo jornalístico da emissora bauruense, além de pesquisa bibliográfica e documental. A principal conclusão é que o espaço regional é limitado por constrangimentos de ordem comercial, por restrições impostas pela cabeça de rede e, ainda, por um projeto de regionalização que não contempla significativamente as nuanças regionais.(AU)

Background: The relationship between deprivation and mortality in urban settings is well established. This relationship has been found for several causes of death in Spanish cities in independent analyses (the MEDEA project). However, no joint analysis which pools the strength of this relationship across several cities has ever been undertaken. Such an analysis would determine, if appropriate, a joint relationship by linking the associations found. Methods: A pooled cross-sectional analysis of the data from the MEDEA project has been carried out for each of the causes of death studied. Specifically, a meta-analysis has been carried out to pool the relative risks in eleven Spanish cities. Different deprivation-mortality relationships across the cities are considered in the analysis (fixed and random effects models). The size of the cities is also considered as a possible factor explaining differences between cities. Results: Twenty studies have been carried out for different combinations of sex and causes of death. For nine of them (men: prostate cancer, diabetes, mental illnesses, Alzheimer’s disease, cerebrovascular disease; women: diabetes, mental illnesses, respiratory diseases, cirrhosis) no differences were found between cities in the effect of deprivation on mortality; in four cases (men: respiratory diseases, all causes of mortality; women: breast cancer, Alzheimer’s disease) differences not associated with the size of the city have been determined; in two cases (men: cirrhosis; women: lung cancer) differences strictly linked to the size of the city have been determined, and in five cases (men: lung cancer, ischaemic heart disease; women: ischaemic heart disease, cerebrovascular diseases, all causes of mortality) both kinds of differences have been found. Except for lung cancer in women, every significant relationship between deprivation and mortality goes in the same direction: deprivation increases mortality. Variability in the relative risks across cities was found for general mortality for both sexes. Conclusions: This study provides a general overview of the relationship between deprivation and mortality for a sample of large Spanish cities combined. This joint study allows the exploration of and, if appropriate, the quantification of the variability in that relationship for the set of cities considered.
