Social network architecture and the maintenance of deleterious cultural traits.

How have changes in communications technology affected the way that misinformation spreads through a population and persists? To what extent do differences in the architecture of social networks affect the spread of misinformation, relative to the rates and rules by which individuals transmit or eliminate different pieces of information (cultural traits)? Here, we use analytical models and individual-based simulations to study how a 'cultural load' of misinformation can be maintained in a population under a balance between social transmission and selective elimination of cultural traits with low intrinsic value. While considerable research has explored how network architecture affects percolation processes, we find that the relative rates at which individuals transmit or eliminate traits can have much more profound impacts on the cultural load than differences in network architecture. In particular, the cultural load is insensitive to correlations between an individual's network degree and rate of elimination when these quantities vary among individuals. Taken together, these results suggest that changes in communications technology may have influenced cultural evolution more strongly through changes in the amount of information flow, rather than the details of who is connected to whom.

On the hardware and software architecture of the robuter mobile platform: a hands-on approach

The Robuter is a robotic mobile platform that is located in the “Hands-On” Laboratory of the IPP-Hurray! Research Group, at the School of Engineering of the Polytechnic Institute of Porto. Recently, the Robuter was subject of an upgrading process addressing two essential areas: the Hardware Architecture and the Software Architecture. This upgrade in process was triggered due to technical problems on-board of the robot and also to the fact that the hardware/software architecture has become obsolete. This Technical Report overviews the most important aspects of the new Hardware and Software Architectures of the Robuter. This document also presents a first approach on the first steps towards the use of the Robuter platform, and provides some hints on future work that may be carried out using this mobile platform.

The Spreading of Christianity and the introduction of Modern Architecture in Shannxi, China (1840-1949): Christian churches and traditional Chinese architecture

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.

Ontogeny of Sleeping in Color - Linking melanism to sleep architecture and rhythmicity variation in wild barn owl nestlings

The function of sleep remains unknown. To gain insight into the function of sleep in natural conditions, I assessed variation in sleep architecture and its link with fitness-related phenotypic traits. I considered melanin-based coloration because its underlying genetic basis is very well known giving an opportunity to examine whether some genes pleiotropically regulate both coloration and sleep. The melanocortin system is known to generate covariation between melanin-based coloration and other phenotypes like behaviour, physiology and life history traits. I investigated whether this system of genes could participate in the co-expression of coloration and sleep. I carried out a study with nestling barn owls (Tyto alba) in order to tackle the potential link between variation in color traits and the ontogeny of sleep under natural conditions. For this I established a suitable method for recording the brain activity (electroencephalogram) of owls in nature. Birds are especially interesting, because they convergently evolved sleep states similar to those exhibited by mammals. As in mammals, I found that in owlets time spent in rapid eye movement (REM) sleep declines with age, a relationship thought to eflect developmental changes in the brain. Thus this developmental trajectory appears to reflect a fundamental feature of sleep. Additionally, I discovered an association between a gene involved in melanism expressed in the feather follicles (proprotein convertase subtilisin/kexin type 2, PCSK2) and the age-related changes in sleep in the brain. Nestlings with higher expression levels of PCSK2 showed a more precocial pattern of sleep development and a higher degree of melanin-based coloration compared to nestlings with lower PCSK2 expression. Also sleep architecture and the development of rhythmicity in brain and physical activity was related to plumage traits of the nestlings and their biological parents. This pattern during ontogeny might reflect differences in life l history strategies, antipredator behaviour and developmental pace. Therefore, differently colored individuals may differentially deal with trade-offs between the costs and benefits of sleep which in turn lead to differences in brain organization and ultimately fitness. These results should stimulate evolutionary biologists to consider sleep as a major life history trait. Résumé La fonction du sommeil reste inconnue. Afin d'acquérir une meilleur compréhension de la fonction du sommeil dans les conditions naturelles, j'ai analysé la variation dans l'architecture du sommeil et son lien avec d'autres traits phénotypiques liés au succès reproducteur (fitness). J'ai choisi et examiné la coloration mélanique, car ses bases génétiques sont bien connues et il est ainsi possible d'étudier si certains gènes, de façon pléiotropique régulent à la fois la coloration et le sommeil. J'ai exploré si ce système génétique était impliqué dans la co-expression de la coloration et du sommeil. J'ai effectué mon étude sur des poussins de chouette effraie (Tyto alba) en condition naturelle, pour rechercher ce lien potentiel entre la variation de la coloration et l'ontogenèse du sommeil. Dans ce but, j'ai établi une méthodologie permettant d'enregistrer l'activité cérébrale (électroencéphalogramme) des chouettes dans la nature. Les oiseaux sont particulièrement intéressants car ils ont développé, par évolution convergente, des phases de sommeil similaires à celles des mammifères. De manière semblable à ce qui a été montré chez les mammifères, j'ai découvert que le temps passé dans le sommeil paradoxal diminue avec l'âge des poussins. On pense que ceci est dû aux changements développementaux au niveau du cerveau. Cette trajectoire développementale semble refléter une caractéristique fondamentale du sommeil. J'ai également découvert une association entre l'un des gènes impliqué dans le mélanisme, exprimé dans les follicules plumeux (proprotein convertase subtilisin/kexin type 2, PCSK2), et les changements dans la structure du sommeil avec l'âge. Les poussins ayant un niveau d'expression génétique élevé de la PCSK2 présentent une structure du sommeil plus précoce et un taux de coloration dû à la mélanine plus élevé que des poussins avec un niveau d'expression moindre de la PCSK2. L'architecture du sommeil et le développement de la rythmicité dans le cerveau ainsi que l'activité physique sont également liés à la coloration des plumes des poussins et pourraient ainsi refléter des différences de stratégies d'histoire de vie, de comportements anti-prédateur et de vitesses développementales. Ainsi, des individus de coloration différente sembleraient traiter différemment les coûts et les bénéfices du sommeil, ce qui aurait des conséquences sur l'organisation cérébrale et pour finir, sur le succès reproducteur. Ces résultats devraient encourager les biologistes évolutionnistes à considérer le sommeil comme un important trait d'histoire de vie. Zusammenfassung Die Funktion von Schlaf ist noch unbekannt. Um mehr Einsicht in diese unter natürlichen Bedingungen zu bekommen, habe ich die Variation in der Schlafarchitektur und die Verknüpfung mit phänotypischen Merkmalen, die mit der Fitness zusammenhängen, studiert. Ich habe mir melanin-basierte Färbung angesehen, da die zugrunde liegende genetische Basis bekannt ist und somit die Möglichkeit gegeben ist, zu untersuchen, ob einige Gene beides regulieren, Färbung und Schlaf. Das melanocortin System generiert eine Kovariation zwischen melanin-basierter Färbung und anderen phänotypischer Merkmale wie Verhalten, Physiologie und Überlebensstrategien. Ich habe untersucht, ob dieses Gensystem an einer gleichzeitigen Steuerung von Färbung und Schlaf beteiligt ist. Dazu habe ich Schleiereulen (Tyto alba) studiert um einen möglichen Zusammenhang zwischen der Variation in der Pigmentierung und der Entwicklung des Schlafs unter natürlichen Bedingungen zu entdecken. Für diese Studie entwickelte ich eine Methode um die Gehirnaktivität (Elektroenzephalogramm) bei Eulen in der Natur aufzunehmen. Vögel sind besonders interessant, da sie die gleichen Schlafstadien aufweisen wie Säugetiere und diese unabhängig konvergent entwickelt haben. Genauso wie bei Säugetieren nahm die Dauer des sogenannten ,,rapid eye movement" (REM) - Schlafes mit zunehmendem Alter ab. Es wird angenommen, dass dieser Zusammenhang die Entwicklung des Gehirns widerspiegelt. Daher scheint dieses Entwicklungsmuster ein fundamentaler Aspekt von Schlaf zu sein. Zusätzlich entdeckte ich einen Zusammenhang zwischen der Aktivität eines Gens in den Federfollikeln (proprotein convertase subtilisin/kexin type 2, PCSK2), das für die Ausprägung schwarzer Punkte auf den Federn der Eulen verantwortlich ist, und den altersabhängigen Änderungen im Schlafmuster im Gehirn. Küken mit höherer Aktivität von PCSK2 zeigten eine frühreifere Schlafentwicklung und eine dunklere Färbung als Küken mit niedriger PCSK2 Aktivität. Die Architekture des Schlafes und die Entwicklung der Rhythmik im Gehirn und die der physischen Aktivität ist mit der Färbung des Gefieders von den Küken und ihren Eltern verknüpft. Dieses Muster während der Entwicklung kann Unterschiede in Überlebensstrategien, Feindabwehrverhalten und in der Entwicklungsgeschwindigkeit reflektieren. Unterschiedlich gefärbte Individuen könnten unterschiedliche Strategien haben um zwischen den Kosten und Nutzen von Schlaf zu entscheiden, was zu Unterschieden in der Gehirnstruktur führen kann und letztendlich zur Fitness. Diese Ergebnisse sollten Evolutionsbiologen stimulieren Schlaf als einen wichtigen Bestandteil des Lebens zu behandeln.
