Crónicas, reliquias, piedras legendarias y coronaciones en la Edad Media

Este artículo es un estudio histórico de la leyenda de la «Piedra del Destino», que fue parte del asiento del trono de coronación de los reyes de Escocia y que fue trasladada a la abadía de Westminster por el rey Eduardo de Inglaterra, que la situó bajo el trono de la coronación de los reyes de Inglaterra. La «Piedra del Destino», como muchas reliquias y antigüedades de la Edad Media, tuvo una larga historia, escrita por cronistas e historiadores. Una historia muy semejante a otras translationes de reliquias. La historia de la «Piedra del Destino» contiene ricos aspectos jurídicos, políticos y sacrales. Para comprenderlos es necesario analizar las crónicas, entendidas como textos históricos, que dan sentido a los rituales jurídicos y políticos de la Edad Media.

Musicoterapia y Arteterapia. Puntos de encuentro en el camino terapéutico

En este artículo pretendemos buscar los aspectos que confluyen en el ámbito de la musicoterapia y el arteterapia, comenzando por su definición y orígenes y siguiendo con los modelos teóricos más importantes. Al analizar los trabajos de investigación elaborados a partir de proyectos en los que se combina la práctica de las dos disciplinas, observamos la necesidad de una mayor interdisciplinareidad. Esto daría lugar a un mayor enriquecimiento de las sesiones y por tanto, del trabajo terapéutico, lo que revertiría en una mejora de la calidad de la intervención.

¿Qué hay en un nombre? –Akko-Ptolemais–´Akka-Acre

La actual ciudad de Akko in Israel, ha tenido muchos nombres a lo largo de los siglos de su prolongado asentamiento. El nombre de Acre, con el que se le conoce en el mundo Occidental, es el residuo del nombre de San Juan de Acre que le dieron sus habitantes cruzados en el s. XII de la era Cristiana. Sin embargo, el nombre de ‘Akko y sus derivados, tienen una larga historia. Bajo tal nombre, aparece ya en las fuentes escritas de comienzos el II Milenio a.C., cuando e produjo la primera urbanización del lugar. Se mantuvo como ‘Akko, ‘Ake, etc…a lo largo de los siglos posteriors, a pesar de los inentos de varios dirigentes de cambiarelo. El asentamiento se trasladó, a causa de los cambios en la línea de costa y del río Na’aman o Belos, desde el antiguo Tel Akko a la bahía, en la que se estableció un puerto artificial,reconstruido y renovado reiteradamente durante más de 2000 años. El primer nombre conocido del sitio original del asentamiento, el tell, data de época de los cruzados. Este sufrió una alteración de su nombre, reflejo de la transformación de la historia de Akko, en la que la intervención occidental (europea9, jugó un papel decisivo.

L'Asse Tripartito Italia-Germania- Giappone e la Cina

Germany, Italy and Japan were engaged in China from the turn of the 20th century to WWII. However, they formed an anti-Chinese alliance only at the final stage of their presence there, when Japan assumed an undisputed role of leader in the region. Despite its alliance with the Axis powers, Japan never implemented racial laws against the Jews in China. All of them took part in the Boxer Upraising suppression and received as a consequence extraterritorial rights and concessions. Moreover, Japan won the war against China in 1895 and transformed itself from a tributary country of China into an imperialistic power. It took possession of Taiwan and in the 1930s established a puppet government in Manchuria.Germany followed different route obtaining as indemnity for the murders of two missionaries the control of the Shandong province, which was later expanded thanks to the anti-Boxer coalition's victory. However, Germany lost all possessions when China entered WWI. The issue of Shandong was finally resolved at the Conference for Disarmament hold in Washington in 1921-2. Japan failed to gain ex-Germany territories. Finally, Italy arrived in the Far East at the turn of the century but was not very interested in the oriental colonialism to the same extent it was interested in Africa. Tianjin was its only concession in China, and it took almost a decade before a subvention to arrive from the Italian government for its development.In the 1920s and 1930s Germany and Italy engaged in successful diplomatic, commercial and military relationships with China. In fact, both were considered China's partners thanks to their experts at the service of the Chinese government. On the other hand, Japan position was opposite to them, because of its plans of aggression towards China which was to be transformed into “the natural extension” of the mainland. In 1935 Italy declared war on Ethiopia and abandoned the seat at the League of Nations. China interpreted the Italian aggression as the endorsement of Japan's politics towards China in Manchuria, and the relations between the two countries were broken off. After that Italy supported Wang Jingwei's puppet government during the Japanese occupation of China. Germany followed the same path in 1937, when it was evident that the Japanese were playing the leading role in the region, and decided to ally with Wang Jingwei too. Both Italy and Germany decided also to recognise the Manzhuguo and established diplomatic relations, definitively turning their backs on the old Chinese ally.The Rome-Berlin-Tokyo Axis sealed the alliance among the three countries, and it confirmed Japan as the leading power in the region. Nevertheless Japan did not apply the racial law against the Jews in China.

IntelliChair: a non-intrusive sitting posture and sitting activity recognition system

Current Ambient Intelligence and Intelligent Environment research focuses on the interpretation of a subject’s behaviour at the activity level by logging the Activity of Daily Living (ADL) such as eating, cooking, etc. In general, the sensors employed (e.g. PIR sensors, contact sensors) provide low resolution information. Meanwhile, the expansion of ubiquitous computing allows researchers to gather additional information from different types of sensor which is possible to improve activity analysis. Based on the previous research about sitting posture detection, this research attempts to further analyses human sitting activity. The aim of this research is to use non-intrusive low cost pressure sensor embedded chair system to recognize a subject’s activity by using their detected postures. There are three steps for this research, the first step is to find a hardware solution for low cost sitting posture detection, second step is to find a suitable strategy of sitting posture detection and the last step is to correlate the time-ordered sitting posture sequences with sitting activity. The author initiated a prototype type of sensing system called IntelliChair for sitting posture detection. Two experiments are proceeded in order to determine the hardware architecture of IntelliChair system. The prototype looks at the sensor selection and integration of various sensor and indicates the best for a low cost, non-intrusive system. Subsequently, this research implements signal process theory to explore the frequency feature of sitting posture, for the purpose of determining a suitable sampling rate for IntelliChair system. For second and third step, ten subjects are recruited for the sitting posture data and sitting activity data collection. The former dataset is collected byasking subjects to perform certain pre-defined sitting postures on IntelliChair and it is used for posture recognition experiment. The latter dataset is collected by asking the subjects to perform their normal sitting activity routine on IntelliChair for four hours, and the dataset is used for activity modelling and recognition experiment. For the posture recognition experiment, two Support Vector Machine (SVM) based classifiers are trained (one for spine postures and the other one for leg postures), and their performance evaluated. Hidden Markov Model is utilized for sitting activity modelling and recognition in order to establish the selected sitting activities from sitting posture sequences.2. After experimenting with possible sensors, Force Sensing Resistor (FSR) is selected as the pressure sensing unit for IntelliChair. Eight FSRs are mounted on the seat and back of a chair to gather haptic (i.e., touch-based) posture information. Furthermore, the research explores the possibility of using alternative non-intrusive sensing technology (i.e. vision based Kinect Sensor from Microsoft) and find out the Kinect sensor is not reliable for sitting posture detection due to the joint drifting problem. A suitable sampling rate for IntelliChair is determined according to the experiment result which is 6 Hz. The posture classification performance shows that the SVM based classifier is robust to “familiar” subject data (accuracy is 99.8% with spine postures and 99.9% with leg postures). When dealing with “unfamiliar” subject data, the accuracy is 80.7% for spine posture classification and 42.3% for leg posture classification. The result of activity recognition achieves 41.27% accuracy among four selected activities (i.e. relax, play game, working with PC and watching video). The result of this thesis shows that different individual body characteristics and sitting habits influence both sitting posture and sitting activity recognition. In this case, it suggests that IntelliChair is suitable for individual usage but a training stage is required.

La résilience des corps - Suivi de - Femmes sans enfant : une impossibilité? Analyse de "La lune dans un HLM" de Marie-Sissi Labrèche et d’ "Un léger désir de rouge" d’Hélène Lépine

Ce mémoire en recherche-création s’articule en deux parties, soit un roman et un essai. La résilience des corps, roman à double narration, met en scène Clara et Romain, un couple dont l’avenir est ébranlé par une grossesse surprise. Dans les chapitres s’alternent les voix des deux personnages, tant dans le passé que dans le présent. La voix de Clara se démultiplie, elle qui souffre de schizophrénie. L’essai Femmes sans enfant : une impossibilité? Analyse de La lune dans un HLM de Marie-Sissi Labrèche et d’Un léger désir de rouge d’Hélène Lépine répond à un questionnement soulevé durant l’écriture du roman, soit « Une femme peut-elle dire, sans se justifier, qu’elle ne veut pas d’enfant? ». Les romans La lune dans un HLM de Marie-Sissi Labrèche et Un léger désir de rouge d’Hélène Lépine sont analysés avec une perspective féministe, de façon à faire ressortir la thématique du refus de la maternité dans le discours et dans les actes des personnages.

Ribeira, técnica versus natureza: transformações em prol de um projeto de modernização (1860-1932)

The necessity of the insertion of the capital of Rio Grande do Norte in the world-wide commercial scene and its claim as the seat of political power, in ends of nineteenth and beginning of twentieth century, determined the direction of urban interventions undertaken by government to restructure the city. In that matter, there were several actions of improvements and embellishment in Natal, which had, as a starting point, the adequacy works of the port, located in the Ribeira quarter, with the aim of ending the physical isolation that reinforced its economic stagnation. Besides the problems faced in the opening bar of the Potengi River, and would complement the required improvements, other barriers demonstrate the tension established between the physic-geographic field and the man: the flooded and slope which connected Cidade Alta and Ribeira the first two quarters of the city.The execution of these works demanded knowledge whose domain and application it was for engineering. But, how the actions done for the engineers, in sense to transform natural areas into constructed spaces made possible the intentional conformation of the quarter of the Ribeira in a commercial and politician-administrative center, in the middle of the XIX century and beginning of the XX? Understand, therefore, the employment effects of technology on the physical-geographical Ribeira, is the objective of this work that uses theoretical and methodological procedures of Urban Environmental History, by analyzing the relationship between the environment and the man, mediated by knowledge and use of technologies. The documental research was used, as primary sources, the Messages of the Provincial Assembly Government that later became the Legislative Assembly of Rio Grande do Norte reports and articles on specialized publications, in addition to local newspapers. The work is structured in five chapters. First, some comments about Urban Environmental History (Chapter 1) supplemented with analysis of the conceptual construction of nature in the Contemporary Era and its application in the city (chapter 02), the following chapters (03 and 04) deal with the rise of engineers as a active group in the Brazilian government frameworks and their vision about the nature inside the urban environment and it is studied how the professional technicians dealt with the improvement work of the harbor and in the shock with the natural forces. Other works that would complement this "project" of modernization and had had natural obstacles to be removed the Ribeira flood and slope constitute the subject of the fifth chapter. Finally, some final considerations retake the initial discussions aiming an association between the technique and the nature as junction elements inside the process of constitution of a Modern Natal

Hybrid mathematical and informational modeling of beam-to-column connections

The analysis of steel and composite frames has traditionally been carried out by idealizing beam-to-column connections as either rigid or pinned. Although some advanced analysis methods have been proposed to account for semi-rigid connections, the performance of these methods strongly depends on the proper modeling of connection behavior. The primary challenge of modeling beam-to-column connections is their inelastic response and continuously varying stiffness, strength, and ductility. In this dissertation, two distinct approaches—mathematical models and informational models—are proposed to account for the complex hysteretic behavior of beam-to-column connections. The performance of the two approaches is examined and is then followed by a discussion of their merits and deficiencies. To capitalize on the merits of both mathematical and informational representations, a new approach, a hybrid modeling framework, is developed and demonstrated through modeling beam-to-column connections. Component-based modeling is a compromise spanning two extremes in the field of mathematical modeling: simplified global models and finite element models. In the component-based modeling of angle connections, the five critical components of excessive deformation are identified. Constitutive relationships of angles, column panel zones, and contact between angles and column flanges, are derived by using only material and geometric properties and theoretical mechanics considerations. Those of slip and bolt hole ovalization are simplified by empirically-suggested mathematical representation and expert opinions. A mathematical model is then assembled as a macro-element by combining rigid bars and springs that represent the constitutive relationship of components. Lastly, the moment-rotation curves of the mathematical models are compared with those of experimental tests. In the case of a top-and-seat angle connection with double web angles, a pinched hysteretic response is predicted quite well by complete mechanical models, which take advantage of only material and geometric properties. On the other hand, to exhibit the highly pinched behavior of a top-and-seat angle connection without web angles, a mathematical model requires components of slip and bolt hole ovalization, which are more amenable to informational modeling. An alternative method is informational modeling, which constitutes a fundamental shift from mathematical equations to data that contain the required information about underlying mechanics. The information is extracted from observed data and stored in neural networks. Two different training data sets, analytically-generated and experimental data, are tested to examine the performance of informational models. Both informational models show acceptable agreement with the moment-rotation curves of the experiments. Adding a degradation parameter improves the informational models when modeling highly pinched hysteretic behavior. However, informational models cannot represent the contribution of individual components and therefore do not provide an insight into the underlying mechanics of components. In this study, a new hybrid modeling framework is proposed. In the hybrid framework, a conventional mathematical model is complemented by the informational methods. The basic premise of the proposed hybrid methodology is that not all features of system response are amenable to mathematical modeling, hence considering informational alternatives. This may be because (i) the underlying theory is not available or not sufficiently developed, or (ii) the existing theory is too complex and therefore not suitable for modeling within building frame analysis. The role of informational methods is to model aspects that the mathematical model leaves out. Autoprogressive algorithm and self-learning simulation extract the missing aspects from a system response. In a hybrid framework, experimental data is an integral part of modeling, rather than being used strictly for validation processes. The potential of the hybrid methodology is illustrated through modeling complex hysteretic behavior of beam-to-column connections. Mechanics-based components of deformation such as angles, flange-plates, and column panel zone, are idealized to a mathematical model by using a complete mechanical approach. Although the mathematical model represents envelope curves in terms of initial stiffness and yielding strength, it is not capable of capturing the pinching effects. Pinching is caused mainly by separation between angles and column flanges as well as slip between angles/flange-plates and beam flanges. These components of deformation are suitable for informational modeling. Finally, the moment-rotation curves of the hybrid models are validated with those of the experimental tests. The comparison shows that the hybrid models are capable of representing the highly pinched hysteretic behavior of beam-to-column connections. In addition, the developed hybrid model is successfully used to predict the behavior of a newly-designed connection.

Economic Development of Urban Areas

In this dissertation I study the development of urban areas. At the aggregate level I investigate how they may be affected by climate change policies and by being designated the seat of governmental power. At the household level I study with coauthors how microfinance could improve the health of urban residents. In Chapter 1, I investigate how local employment may be affected by electricity price increases, which is a likely consequence of climate change policies. I outline how previous studies that find large, negative effects may be biased. To overcome these biases I develop a novel estimation strategy that blends border-pair regressions with the synthetic control methodology. I show the conditions for consistent estimation. Using this estimator, I find no effect of contemporaneous price changes on employment. Consistent with the longer time-frame for manufacturing decisions, I do find evidence for negative effects from perceived permanent price shocks. These estimates are much smaller than previous research has found. National capital cities are often substantially larger than other cities in their countries. In Chapter 2, I investigate whether there is a causal effect from being a capital by studying the 1960 relocation of the Brazilian capital from Rio de Janeiro to Brasília. Using a synthetic controls strategy I find that losing the capital had no significant effects on Rio de Janeiro in terms of population, employment, or gross domestic product (GDP). I find that Brasília experienced large and significant increases in population, employment, and GDP. I find evidence of large spillovers from the public to the private sector. Chapter 3 investigates how microfinance could increase the uptake of costly health goods. We study the effect of time payments (micro-loans or micro-savings) on willingness-to-pay (WTP) for a water filter among households in the slums of Dhaka, Bangladesh. We find that time payments significantly increase WTP: compared to a lump-sum up-front purchase, median WTP increases 83% with a six-month loan and 115% with a 12-month loan. We find that households are quite patient with respect to consumption of health inputs. We find evidence for the presence of credit and savings constraints.
