Between "uxor", "mater" and "concubina". Profile and identity of the Emperor Constantine in Late Roman legislation

We aspire to shape the Constantine’s personality in particular by analyzing his loving relationship, first with Minervina and then with Fausta, and not forgetting the bond with his mother Helena, hence the reference to uxor, mater and concubina in our title. We will analyze if these women exercised any influence on the composition of his production rules and, if so, to what extent they were able to determine the historical development of the following decades. From this point of view we must consider in general the emperor had to combine their political claims and government with these relationships, showing great skill in handling times and ways, always putting the first to the second.

Antiguas comunidades judías en Macedonia, Tracia y Épiro Superior

Evidencias de carácter literario, epigráfico y arqueológico-arquitectónicas, atestiguan la existencia de comunidades judías en Macedonia, Tracia y Épiro Superior (hoy Albania) durante los períodos romano y bizantino temprano. Los Hechos de los Apostoles mencionan la presencia de comunidades judías, y sus sinagogas, en Filipos, Tesalónica y Verroia, en Macedonia. El descubrimiento de inscripciones griegas en Bizya (Tracia), en Tesalónica y Dión, y en la antigua sinagoga de Stobia, sugieren que dichas comunidades preservaron su independencia religiosa y gozaron de un seguro estatus social, económico y cultural. Una antigua tumba judía encontrada en Tesalónica, decorada con una menorah, la sinagoga de Claudius Tiberius Polycharmos en Stobia y la de Saranda (Épiro Superior), añaden pruebas arqueológico- arquitectónicas a las fuentes literarias. A pesar de que las fuentes literarias, los datos epigráficos y los hallazgos arqueológicos son relativamente escasos, parece que en estas regiones, y en otras de la Península Balcánica, existieron también otras comunidades judías.

Urban Ponds as an Aquatic Biodiversity Resource in Modified Landscapes

Urbanization is a global process contributing to the loss and fragmentation of natural habitats. Many studies have focused on the biological response of terrestrial taxa and habitats to urbanization. However, little is known regarding the consequences of urbanization on freshwater habitats, especially small lentic systems. In this study we examined aquatic macroinvertebrate diversity (family and species level) and variation in community composition between 240 urban and 782 non-urban ponds distributed across the UK. Contrary to predictions, urban ponds supported similar numbers of invertebrate species and families compared to non-urban ponds. Similar gamma diversity was found between the two groups at both family and species taxonomic levels. The biological communities of urban ponds were markedly different to those of non-urban ponds and the variability in urban pond community composition was greater than that in non-urban ponds, contrary to previous work showing homogenisation of communities in urban areas. Positive spatial autocorrelation was recorded for urban and non-urban ponds at 0-50 km (distance between pond study sites) and negative spatial autocorrelation was observed at 100-150 km, and was stronger in urban ponds in both cases. Ponds do not follow the same ecological patterns as terrestrial and lotic habitats (reduced taxonomic richness) in urban environments; in contrast they support high taxonomic richness and contribute significantly to regional faunal diversity. Individual cities are complex structural mosaics which evolve over long periods of time and are managed in diverse ways, promoting the development of a wide-range of environmental conditions and habitat niches in urban ponds which can promote greater heterogeneity between pond communities at larger scales. Ponds provide an opportunity for managers and environmental regulators to conserve and enhance freshwater biodiversity in urbanized landscapes whilst also facilitating key ecosystem services including storm water storage and water treatment.

Caracterização geológica e geofísica da área do porto da Figueira da Foz

No âmbito de um projeto realizado para a Administração Portuária do Porto da Figueira da Foz, foram recolhidos dados geofísicos no offshore da costa da Figueira da Foz, utilizando um sistema combinado de sonar de varrimento lateral e de sísmica de alta resolução com o objetivo de compreender a distribuição de sedimentos ao longo do fundo marinho e assim entender melhor a sua origem. Os dados de varrimento lateral foram processados, analisados e representados em mosaicos recorrendo ao software integrado TRINTON Prespective. Foram colhidas 10 amostras de sedimentos de fundo que foram analisadas do ponto de vista granulométrico e que foram usadas para a calibração dos mosaicos do sonar de varrimento lateral de modo a produzir um mapa semi-quantitativo de classificação dos sedimentos de fundo. Os dados de reflexão sísmica foram processados e analisados através dos softwares SPW e RadExPro. Os mapas de sonar de varrimento lateral produzidos (mosaicos) mostram uma relação entre o tamanho de grão e composição dos depósitos de plataforma interna e os processos geológicos que ocorrem na zona costeira adjacente. Também se verifica uma relação entre a orientação da costa e a sua consequente exposição às ondas incidentes, e como isso afeta e altera a distribuição do tamanho grão. Neste contexto, a interpretação combinada dos mosaicos do sonar de varrimento lateral com os dados de granulometria e a batimetria dos sedimentos permitiram uma cartografia interpretativa detalhada da morfologia do mar, uma melhor compreensão do controlo da linha costeira na propagação das ondas e correntes e, por conseguinte, na transferência de sedimento no litoral. Os dados de sísmica permitem ainda verificar a espessura das várias camadas geológicas em profundidade.

Using augmented state Kalman filter to localize multi autonomous underwater vehicles

The present paper describes a system for the construction of visual maps ("mosaics") and motion estimation for a set of AUVs (Autonomous Underwater Vehicles). Robots are equipped with down-looking camera which is used to estimate their motion with respect to the seafloor and built an online mosaic. As the mosaic increases in size, a systematic bias is introduced in its alignment, resulting in an erroneous output. The theoretical concepts associated with the use of an Augmented State Kalman Filter (ASKF) were applied to optimally estimate both visual map and the fleet position.

Aprendizaje basado en problemas, ABP : una propuesta para transformar la enseñanza-aprendizaje de las aplicaciones de la trigonometría en la solución de triángulos en el grado 10º

El estudio tuvo como propósito determinar la efectividad relativa del ABP, comparado con el método tradicional para desarrollar habilidades de resolución de problemas en el aprendizaje de las aplicaciones de la solución de triángulos en el grado 10º de la Institución Educativa El Progreso, de El Carmen de Viboral, Antioquia. La enseñanza-aprendizaje de las matemáticas sustentadas con la estrategia didáctica Aprendizaje Basado en Problemas permite a los estudiantes y docentes aproximarse al conocimiento de una manera similar a como lo hacen los científicos; el primer paso es una situación de duda, perplejidad del estudiante provocada por la Situación Problema planteada por el docente, el segundo un momento de “sugerencias” en las que la mente salta hacia adelante en busca de una posible solución (Dewey, 1933, p. 102). El tercer paso “intelectualización” de la dificultad que se ha percibido para convertirlo en un problema que debe solucionarse (Dewey, 1933, p. 103). La cuarta es “la idea conductora o hipótesis”, las cuales se basan en la formulación de explicaciones sugeridas o soluciones posibles (Dewey, 1933, p. 104). El quinto paso sería el “razonamiento”, consiste en la elaboración racional de una idea que se va desarrollando de acuerdo a las habilidades de cada persona (Dewey, 1933, p. 105). El paso final es la “comprobación de hipótesis” en situaciones reales. Este proceso se evidenció a través de cuatro Situaciones-Problema enfocadas desde un contexto auténtico “la remodelación del parque principal de El Carmen de Viboral” con el objetivo de motivar a los estudiantes para el aprendizaje de algunos conceptos matemáticos y el desarrollo de habilidades de resolución de problemas. La metodología de la investigación fue un diseño cuasi-experimental con grupo experimental compuesto por 38 estudiantes del grado 10º2 y grupo control con 37 estudiantes del grado 10º1. Se empleó como técnica de recolección de la información una prueba pre-test antes del tratamiento y una prueba post-test que se aplicó después del tratamiento a ambos grupos; se aplicó también una escala de satisfacción de los estudiantes con la metodología tradicional en ambos grupos y una escala de satisfacción con la estrategia didáctica ABP sólo al grupo experimental; la observación directa, y el portafolio que evidenciaba todas las construcciones de los estudiantes. La aplicación de la estrategia didáctica experimental se aplicó durante 4 meses, con una intensidad horaria de cuatro horas semanales, tiempo durante el cual se implementaron las cuatro Situaciones-Problema. Se concluyó entre otros aspectos que el 86,5% de los estudiantes encuentran las clases de matemáticas como interesantes, contextualizadas, aplicables y significativas, mientras que antes del tratamiento sólo el 44,4% se encontraba satisfecho con las clases de matemáticas, con una diferencia en cambio de actitud de 42,1% frente a las clases de matemáticas con la metodología tradicional. En el análisis comparativo de adquisición de competencias específicas se demuestra que el grupo experimental demostró ser matemáticamente más competente con respecto al grupo control en todas las competencias evaluadas: capacidad de modelación, inductiva, comunicativa y habilidad procedimental. Además, el proyecto de investigación tuvo un valor agregado: 10 estudiantes tuvieron la oportunidad de conocer más sobre su cultura ceramista mediante el diseño y construcción de mosaicos que los ofreció la casa de la cultura en forma gratuita.

Aetius of Amida. Libri Medicinales Book 1: A Translation with Commentary

This work is the first translation into a modern language of book 1 of the Libri Medicinales of Aëtius of Amida, a Byzantine physician who wrote in the middle of the 6th century AD. It comprises a lengthy preface, describing the analysis of pharmacological materials in terms of the science of the time, followed by 418 chapters, listing such materials obtained from plants. Commentary is to be found in the Introduction, as well as a running commentary after each part of the preface and each chapter. As Aëtius’ book 1 is a synopsis of the plants section of Galen’s On the Mixtures and Capacities of Simple Drugs, particular attention is paid to comparison between Aëtius’ work and that of Galen. Evaluation of the efficacy and safety of the ancient drugs in the light of modern scientific knowledge, a relatively neglected area of research, has also been given serious consideration.

Les relations entre chrétiens orthodoxes et musulmans en Europe du sud-est durant le XIVe et XVe siècle.

Le sujet de cette thèse est les relations interreligieuses entre les chrétiens orthodoxes et les musulmans en Europe du Sud-Est durant le XIVe et XVe siècle. La thèse réalise une réinterprétation de l’histoire prisonnière des interprétations idéologiques et religieuses grâce à une méthodologie faisant appel à la démythologisation et à la démythification. Les différents religieux entre le christianisme et l'islam ont servi comme une justification aux conflits politiques et nationaux dans cette région européenne et cela même jusqu’au XXIe siècle. En relisant les grands moments de cette histoire dans diverses régions des Balkans et la thèse s’attarde à des aspects positifs de leurs relations, leur coopération, leur coexistence et c'est qui est le plus important, le dialogue interreligieux avec les représentants de l'Église orthodoxe de Constantinople et de l'Empire byzantin avant et après la chute de Constantinople en 1453. La chute de la capitale byzantine, qui avait l'importance d'un centre ecclésiastique et spirituel de l'Église orthodoxe, est un fait historique qui est devenu le symbole de la conquête ottomane et musulmane en Europe dans les sources et les interprétations. La démythification de cette histoire laisse poindre d’autres lectures possibles des relations qui se sont construites à cette époque, ce qui a un impact sur la situation actuelle de cette région du monde.

La synthèse philosophico-juridique de V.S. Soloviev : élaboration et mise en œuvre d’un cadre théorique

Vladimir S. Soloviev (1853-1900) était un philosophe russe, poète et dissident de la période prérévolutionnaire. Comme celle de beaucoup de ses contemporains prérévolutionnaires russes, la pensée de Soloviev fut constamment sollicitée par la réfection imminente de l’État russe dans un futur très proche. Dans le contexte de cette époque, un examen des fondements théoriques du système juridique était peut-être inévitable. Néanmoins, dans la pensée russe, c’est seulement avec Soloviev que le droit cessa d’être un sujet spécialisé dans le domaine de l’administration, ne concernant guère les grands enjeux de société, et devint intimement lié au développement même de la philosophie morale et sociale. Au sein du projet philosophique systématique que propose Soloviev, le concept de l’unitotalité est envahissant, en termes épistémologique et social. Une pierre d’assise également fondamentale est le concept philosophico-religieux de la divino-humanité, à travers lequel la source de la dignité humaine est ultimement exprimée. La philosophie juridique de Soloviev, contenue pour l’essentiel dans un traité intitulé La Justification du bien : essai de philosophie morale (1897), a pour principal objet l’interaction entre le droit et la morale. Alors que l’objet et la portée du droit peuvent être directement déduits de principes moraux, le droit ne peut pas coïncider exactement avec la morale, compte tenu de son caractère plus limité, fini et coercitif. Pour Soloviev, le droit doit imposer un niveau minimum du bien en fournissant les conditions de base (par ex. la primauté du droit, le droit à une existence digne, la liberté de conscience) pour le libre développement des facultés humaines sans transposer directement en lui la plénitude complète du bien. La principale motivation de Soloviev réside dans la prémisse théologique sous-jacente que le bien ne peut jamais être complètement subsumé sauf par un acte conscient de liberté personnelle. En tandem, Soloviev souligne le rôle progressiste de l’État pour favoriser le libre perfectionnement humain. En tant que tel, Soloviev nous fournit certaines voies innovatrices dans le façonnement de la relation tant théorique que pratique entre le droit et la religion. À l’encontre d’un compromis entre objets, c’est-à-dire un arrangement de type interculturel situé entre fragmentation culturelle (multiculturalisme idéologique) et assimilation antireligieuse (laïcité militante), l’analyse de Soloviev présente la nécessité d’une conciliation temporelle, dans une perspective historique beaucoup plus large, où la laïcité est considérée non pas comme une finalité ontologique en soi, figée dans le temps, mais comme un moyen au service d’une destinée humaine en cours d’actualisation. Le cadre philosophico-juridique de Soloviev peut être utilement mis en dialogue avec des auteurs contemporains comme Stephen L. Carter, Charles Taylor, John Witte Jr, Ronald Dworkin et Jürgen Habermas. La contribution potentielle de Soloviev sur la place de la religion dans la société russe contemporaine est également mentionnée, avec un accent particulier sur le réexamen critique de l’héritage durable de la notion byzantine de la symphonie entre l’Église et l’État. Enfin, une théorie du fédéralisme inspirée par Soloviev est développée en appliquant, sur une base comparative, des avancées théoriques dans le domaine de l’histoire juridique global à l’évolution constitutionnelle du Canada et d’Israël.

Typologies and spatialization of agricultural production systems in Rondônia, Brazil: linking land use, socioeconomics and territorial configuration.

The current Amazon landscape consists of heterogeneous mosaics formed by interactions between the original forest and productive activities. Recognizing and quantifying the characteristics of these landscapes is essential for understanding agricultural production chains, assessing the impact of policies, and in planning future actions. Our main objective was to construct the regionalization of agricultural production for Rondônia State (Brazilian Amazon) at the municipal level. We adopted a decision tree approach, using land use maps derived from remote sensing data (PRODES and TerraClass) combined with socioeconomic data. The decision trees allowed us to allocate municipalities to one of five agricultural production systems: (i) coexistence of livestock production and intensive agriculture; (ii) semi-intensive beef and milk production; (iii) semi-intensive beef production; (iv) intensive beef and milk production, and; (v) intensive beef production. These production systems are, respectively, linked to mechanized agriculture (i), traditional cattle farming with low management, with (ii) or without (iii) a significant presence of dairy farming, and to more intensive livestock farming with (iv) or without (v) a significant presence of dairy farming. The municipalities and associated production systems were then characterized using a wide variety of quantitative metrics grouped into four dimensions: (i) agricultural production; (ii) economics; (iii) territorial configuration, and; (iv) social characteristics. We found that production systems linked to mechanized agriculture predominate in the south of the state, while intensive farming is mainly found in the center of the state. Semi-intensive livestock farming is mainly located close to the southwest frontier and in the north of the state, where human occupation of the territory is not fully consolidated. This distributional pattern reflects the origins of the agricultural production system of Rondônia. Moreover, the characterization of the production systems provides insights into the pattern of occupation of the Amazon and the socioeconomic consequences of continuing agricultural expansion.

Naturaleza y elementos naturales en la Apología contra los judíos de Leoncio de Neápolis : Un análisis retórico

En la presente comunicación nos proponemos estudiar el texto de Leoncio de Neápolis (Chipre, s. VII d. C.) conocido con el título Apología o Apología contra los judíos. La obra pertenece a la tradición literaria adversus iudaeos y se enmarca en la polémica por el uso religioso de imágenes sacras. Nos centraremos en particular en el análisis de la forma en la que aparecen representados en la obra los elementos naturales y las menciones de la naturaleza, ya sea a través de imágenes y metáforas, descripciones o ekphráseis, citas del Antiguo Testamento y reflexiones filosóficas. En un primer lugar, ofreceremos una clasificación de dichas representaciones, para luego definir de qué modo éstas funcionan de manera cohesiva en el dispositivo retórico general de la obra, en tanto que contribuyen al propósito persuasivo en favor del uso de imágenes. Tendremos en cuenta para el tratamiento del tema los aportes de H. Maguire (sobre todo, Nectar and Illusion: Nature in Byzantine Art and Literature, Oxford, 2012 y "The Profane Aesthetic in Byzantine Art and Literature", Dumbarton Oaks Papers 53, 1999, pp. 189-205)

Characterization of plasmids in a human clinical strain of Lactococcus garvieae

The present work describes the molecular characterization of five circular plasmids found in the human clinical strain Lactococcus garvieae 21881. The plasmids were designated pGL1-pGL5, with molecular sizes of 4,536 bp, 4,572 bp, 12,948 bp, 14,006 bp and 68,798 bp, respectively. Based on detailed sequence analysis, some of these plasmids appear to be mosaics composed of DNA obtained by modular exchange between different species of lactic acid bacteria. Based on sequence data and the derived presence of certain genes and proteins, the plasmid pGL2 appears to replicate via a rolling-circle mechanism, while the other four plasmids appear to belong to the group of lactococcal theta-type replicons. The plasmids pGL1, pGL2 and pGL5 encode putative proteins related with bacteriocin synthesis and bacteriocin secretion and immunity. The plasmid pGL5 harbors genes (txn, orf5 and orf25) encoding proteins that could be considered putative virulence factors. The gene txn encodes a protein with an enzymatic domain corresponding to the family actin-ADP-ribosyltransferases toxins, which are known to play a key role in pathogenesis of a variety of bacterial pathogens. The genes orf5 and orf25 encode two putative surface proteins containing the cell wall-sorting motif LPXTG, with mucin-binding and collagen-binding protein domains, respectively. These proteins could be involved in the adherence of L. garvieae to mucus from the intestine, facilitating further interaction with intestinal epithelial cells and to collagenous tissues such as the collagen-rich heart valves. To our knowledge, this is the first report on the characterization of plasmids in a human clinical strain of this pathogen.

La santidad compartida: la encrucijada del Islam y la ortodoxia cristiana en los Balcanes, reflejos en Bulgaria

In this doctoral thesis with the title: “The Shared Holiness: The crossroad of Islam and the Christian Orthodoxy in the Balkans, reflections in Bulgaria”, presented by VLADISLAVA SPASOVA ILIEVA, under the direction of Dr. MONTSERRAT ABUMALHAM MAS, and Dr. PEDRO BÁDENAS DE LA PEÑA, we reflect upon the crossroads between the populations in the Balkans, whose conversion into States was significantly influenced by their belonging to the Byzantine and the Ottoman Empires. Known as the crossroads of several cultures, the area was the destination of a massive influx of pagan Slaves, as well as the meeting point of Islam and Christianity. Considering the bidirectionality of the processes, we shall focus on the mutual enrichment brought about in the encounter between the religiosities of the Balkans, and we will discuss these points from different perspectives. In the common Balkan-Anatolian space, we turn our attention to the ancient hermits, with the aim of showing the complicity in the relations of coexistence, whether Islamic-Christian, Turkish-Byzantine, Turkish-Bulgarian, or Ottoman-Balkan, and a possible scheme, that could be valid for both social and spiritual growth of the person, as well as for the development of an ethnic or religious community, when sharing the same space with other populations, communities or ethnicities...
