The Catholic Church and Mexican American Social Mobility in the Postwar Midwest: Evidence from Life and Family Histories
Authors: Ruiz Bienvenido , Guerra Ramon S. , Lomeli Arlett S. , Longoria Rolando R. , Ulibarrí Billy James
Published: April 2017

Religious affiliation has long been recognized as a relevant factor among the variables that intervene in the integration of immigrants to American society. While previous generations of many predominantly Roman Catholic ethnic groups are thought to have been helped along their way to assimilation by strong institutional support from American Catholic church institutions, Latinos, and in particular Mexican Americans, are considered an exception. This study examines the role that inclusion in Catholic institutions played in the social mobility experienced by multigenerational families of Mexican immigrant origin in the Midwest during the decades between 1945 and 1975. The analysis of life and family histories collected from in-depth interviews with older second- and third-generation Mexican Americans illustrates how integration into urban Catholic institutions and communities was instrumental in the upward social mobility observed in many of their family trajectories during the postwar decades. In particular, access to parochial schools and other institutions in the Catholic educational system once provided the children and grandchildren of Mexican immigrants the forms of human and social capital that allowed many in that generation to attain social mobility.

Published: April 2017

Professional societies have published recommendations for iron dosing of preterm neonates, but differences exist between guidelines. To help develop standardized guidelines, we performed a 10-year analysis of iron dosing in groups at risk for iron deficiency: IDM (infants of diabetic mothers), SGA (small for gestational age), and VLBW premature neonates (very low birth weight, <1500 g). We analyzed iron dosing after red cell transfusions and erythropoiesis-stimulating agents (ESA). Of IDM, 11.8% received iron in the hospital; 9.8% of SGA and 27.1% of VLBW neonates received iron. Twenty percent of those who received iron had it started by day 14; 63% by 1 month. Supplemental iron was stopped after red cell transfusions in 73% of neonates receiving iron. An ESA was administered to 1677, of which 33% received iron within 3 days. This marked variation indicates that a consistent approach is needed, and using this report and a literature review, we standardized our iron-dosing guidelines.

Evidence of disease control: a realistic concept beyond NEDA in the treatment of multiple sclerosis
Authors: Londoño Ana C. , Mora Carlos A.
Published: April 2017

Although no evidence of disease activity (NEDA) permits evaluation of response to treatment in the systematic follow-up of patients with multiple sclerosis (MS), its ability to accomplish detection of surreptitious activity of disease is limited, thus being unable to prevent patients from falling into a non-reversible progressive phase of disease. A protocol of evaluation based on the use of validated biomarkers that is conducted at an early stage of disease would permit the capture of abnormal neuroimmunological phenomena and lead towards intervention with modifying therapy before tissue damage has been reached.
Tri-Vizor Uses an Efficient Algorithm to Identify Collaborative Shipping Opportunities
Authors: Creemers Stefan , Woumans Gert , Boute Robert , Beliën Jeroen
Published: April 2017

Collaborative shipping programs, whereby companies bundle their transport loads, are a growing trend in logistics. By bundling shipments with other partners, available space in truck hauls for one company can be used to transport shipments for other companies. The benefits are reduced logistics costs and a lower carbon footprint. Although the advantages of collaborative shipping are clear, finding suitable collaboration partners is a major impediment. In this article we present a tool that enables the quick identification of potential partners based on their geographical compatibility, even when the database of shipment lanes is very large. The tool allows the detection of bundling, back-hauling, and round-trip opportunities, as well as “collect-and-or-drop” opportunities in which shipments are collected and (or) dropped off en route. Tri-Vizor, a facilitator and orchestrator of horizontal logistics partnerships, is currently using this tool. Any company that is looking for collaborative shipping partners would also find it valuable. For Tri-Vizor, whose database has grown to over 130,000 shipment lanes, this tool has become an indispensable asset in detecting collaborative shipping opportunities.
Designing urban agriculture education for social justice: Radical innovation through Farm School NYC
Authors: Reynolds Kristin
Published: April 2017

This article examines one example of radical innovation and everyday design through a case study of Farm School NYC, an adult education programme in New York City that uses critical pedagogy and popular education to train adult students in urban farming, social justice advocacy and teaching skills. Drawing primarily from research conducted between 2013 and 2014 for a study on urban agriculture and social justice activism, the article illustrates how a network of urban agriculture practitioners, educators and activists created a community-based training programme that takes steps towards a broad vision of a socially just urban food system and that this represents a case of everyday design by radical innovation. It argues that understanding ways in which projects like Farm School NYC infuse radical visions of social change into their day-to-day educational activities is useful for those interested in supporting such transformative work through teaching, farming and gardening and design.
A Simple But Effective Landslide Detection Method Based on Image Saliency
Authors: Yu Bo , Chen Fang , Muhammad Shakir , Li Bin , Wang Li , Wu Mingquan
Published: April 2017

Effective large-scale landslide mapping is becoming significantly important for analyzing natural hazards and providing landslide locations rapidly for emergency response. Change detection and machine learning methods are commonly used for landslide detection. Change detection mostly
relies on several experienced parameters that users have to tune for different images, which limits the practical application. The training machine learning model consumes much time, and it is limited to specific imaging conditions. In this paper, a simple method for landslide detection using
a fixed parameter by calculating image saliency is proposed. Landslide is detected as a saliency object within the background of vegetation and bare rocks. It is fast and robust for the experimental images, and outperforms the state-of-the-art, semi-automatic method in terms of accuracy and
computing time. Given the high efficiency and robustness of the proposed method, it is applicable to practical cases for hazard estimation.

Reflexiones y propuestas críticas: Epistemología y Didáctica de la Historia: clave esencial en la formación didáctico–disciplinar del profesorado.
Authors: De la Montaña Conchiña Juan Luis
Published: April 2017

En el capítulo de la formación inicial de futuros maestros y maestras se hace cada vez más patente la necesidad de introducirles en el conocimiento epistemológico de las disciplinas a enseñar, en nuestro caso la historia. Introducirles en este conocimiento y fomentar la reflexión sobre cómo se construye el conocimiento, el qué y para qué de la historia, las opciones historiográficas existentes, nos parece clave en la mejora de la enseñanza–aprendizaje de esta disciplina.Estas afirmaciones se apoyan en los resultados obtenidos de los análisis de concepciones sobre la historia realizados sobre varios grupos de docentes en formación. En general, el profesorado en formación muestra un conocimiento estereotipado, muy limitado —no sólo en conocimientos disciplinares— de la historia y mediatizado por influencias diversas (la historia en sus dimensiones públicas, medios de comunicación).Cambiar esta concepción de la historia puede fomentarse desde la reflexión y el conocimiento epistemológico de disciplina, resultando ser un paso imprescindible para afrontar el ejercicio de una didáctica de esta disciplina acorde con las necesidades de las sociedades modernas.

The human society since early times has utilized the fire as a mean to accomplish its own needs and fuel providing has always been its main concern. In the framework of the environmental and forestry protection increasingly is required the retrievable and sustainable alternative energy. The utilization of reed biomass is an alternative of the retrievable biomass. The world is using since many years the reed biomass as fuel source. Whereas in Albania the utilization of the reed biomass has been observes only in the framework of projects in protected areas. Our proposal to plant 500 ha peaty soil, recently an abandoned agricultural land which is waterlogged for a long period of the year, is seen as a possibility for the re-cultivation of abandoned lands, to produce the renewable biomass. By assessment results that from this surface to provide at least 5000 ton reed biomass or about 86500 GJ energy. This energy is a considerable source of energy and a way to reduce the deforestation, at least to the region in this study.
Catabatic Winds in Oraviţa Depression (Romania). Case Studies
Authors: Chiriac Ciprian , Murărescu Ovidiu
Published: April 2017

In some situations, field positioning of air pressure through development of anticyclone in the north - northeast of Romania and a cyclone in the south-west, create conditions favoring intensifying dynamics of air masses in Oraviţa Depression area. This phenomenon generates a catabatic wind which is known local as Coşava. Mode of expression is as strong intensification of the burst, which gives rise to considerable material damages. This study takes into account the analysis of three cases considered by us to be representative.
Frames of subspaces in Hilbert spaces with W-metrics
Authors: Acosta-Humánez Primitivo , Esmeral Kevin , Ferrer Osmin
Published: April 2017

In this paper we start considering a sesquilinear form 〈W·,·〉 defined over a Hilbert space (ℌ,〈·,·〉) where W is bounded (W* = W ∈ Ɓ(ℌ)) and ker W = {0}. We study the dynamic of frame of subspaces over the completion of (ℌ, 〈W·,·〉) which is denoted by ℌW and is called Hilbert space with W-metric or simply W-space. The sense of dynamics studied here refers to the behavior of frame of subspaces comparing ℌW with ℌ as well ℌ with ℌW. Furthermore, we show that for any Hilbert space with W-metric ℌW, being 0 an element of the spectrum of W (0 ∈σ(W)), has a decomposition ℌW = ⊕n∈ℕ∪{∞}ℌW
ψn where ℌW
ψn ≃ L2(σ(W), χdμn(χ)) for all n ∈ ℕ ∪ {∞}, L2 denotes a Hilbert space square integrable and μ a Lebesgue measure. Finally, the case when W is unbounded also considered.

The Features of the Cyclical Fluctuations, Homogeneity and Stationarity of the Average Annual Flow of the Southern Buh River Basin
Authors: Bauzha Tetiana , Gorbachova Liudmyla
Published: April 2017

In the last decades, according to researches of scientists of the world becomes more evident that the global and regional climate changes impact on the water regime of rivers and leads to break of the stationarity of observations series. In this study we analysed the long-term (since the beginning of the observations to 2012) average annual flow of the Southern Buh River Basin (37 gauging stations) and its cyclical fluctuations during a long period of time. The methodological approaches based on the using of hydro-genetic methods for estimation the homogeneity and stationarity of hydrological series were used. We researched that series of observations are homogeneous and stationary. However, not all series of observations were representative for determination of the stable average value. The presented results illustrate that the long-term fluctuations of the average annual flow at all gauging stations is synchronous. Therefore, the climatic conditions of the flow formation are homogeneous. However, these fluctuations are not always synchronous phase. We found out that the average annual flow in this basin fluctuates and has decreasing trend in the last decade. It is due to cyclical fluctuations of the river flow. We calculated the statistical parameters for all gauging stations.

Published: April 2017

The main objective of this study is to classify the landforms of Ikaria Island by conducting morphometric analysis. The whole classification process is based on the calculation of the Topographic Position Index (TPI). The delivered TPI landform classes are spatially correlated with the geology, slope, valley depth and the topographic ruggedness of the island. The results of this study indicate the presence of two distinctive landform units, affected mainly by the local geological setting.
Estimation of Soil Erosion in Rodnei Mountains National Park Using G.I.S. Technique
Authors: Flămînd Lazăr , Moldovan Maria-Olivia , Corabian Izabella , Gliga Iulia Diana
Published: April 2017

Erosion is one of the biggest and most widely spread forms of soil degradation, having an impact on both the surrounding environment and the economical one as well. According to a recent study from 2014-2015 by the Common Research Center an estimate of approximately 11.4% of the EU’s territory has been affected by the erosion process in moderate to high levels, the soil’s erosion rate being higher than 5t/ha/year. A significant part of Romania’s surface feels the negative effects of the soils degradation, erosion being the most widely spread long-term complex phenomena. Identifying as exactly as possible the areas with erosion risk is recommended in order to intervene with measures of consolidation, leveling, terrain modeling and other hydro-improving constructions. For this reason, for the studied area, Rodnei Mountains National Park (Maramureș County, Bistrita-Nasaud County), having a surface of 47.177 ha, the soil’s erosion has been modeled via the USLE model, developed by Motoc in 1979, taking into consideration all the climate conditions specific to Romania. Following the implementation of the G.I.S environment model, the soil’s erosion estimate values have been obtained, subsequently being divided in 8 classes of erosion, losses of soil less than 0.5t/ha/year representing 89.3% out of the park’s total surface. Researching the model’s obtained results and comparing them to existing values of soil erosion, locally and nationally, we can draw the conclusion that the results of the USLE model are truthful, and that the model can be successfully used in the studied area. Thereby, the study has targeted the determination of vulnerabilities at the erosional processes and vulnerabilities to erosion, the risk of erosion susceptibility being assessed.
Microstructure characterization of localized corrosion wear of Cr/Cr2N+ a-C:H/a-C:H:Cr multilayer coatings on carbon fiber composites
Authors: Janusz M. , Major L. , Lackner J. M. , Grysakowski B. , Krawiec H.
Published: April 2017

The use of carbon fiber composites (CFC) for different applications is widespread. Carbon-based materials show, however, significant oxidative degradation in air. Modern materials are subjected to aggressive, corrosive environment. This type of environment may strongly reduce their mechanical properties. For the protection of CFC, it was necessary to apply coatings to the composite surface. In the presented paper, a chromium/chromium nitride (Cr/Cr2N) multilayer structure has been selected as the inner part. The outer part of the coating was a hydrogenated amorphous carbon (a-C:H), gradually implanted by Cr nanocrystals. The application of transmission electron microscopy (TEM) indicated that the proposed deposition method allowed the formation of a Cr/Cr2N multilayer of Λ = 150 nm, topped with a-C:H+ Cr23C6 composite of a varied carbides density. The micro-hardness of the deposited coatings was up to 14 GPa (at a load of 2 and 5 mN). The microstructure of the deposited coatings was described in detail by means of TEM in the authors’ recently published paper [1]. This paper is a continuation thereof, aimed at describing microstructure changes after a localized corrosion process. In order to study localized corrosion in coatings, particularly in metallic (Cr) interlayers, the potential measurements and voltammetry experiments were performed in a Ringer solution. The open-circuit potential reaches stable values after a sufficient time period. The results indicated that the presence of a-C:H+Cr23C6, the outer part of the coating, speeds up the localized corrosion process in Cr interlayers in the inner part of a coating.
Parallel anisotropic mesh refinement with dynamic load balancing for transonic flow simulations
Authors: Gepner S. , Majewski J. , Rokicki J.
Published: April 2017

The present paper discusses an effective adaptive methods suited for use in parallel environment. An in-house, parallel flow solver based on the residual distribution method is used for the solution of flow problems. Simulation is parallelized based on the domain decomposition approach. Adaptive changes to the mesh are achieved by two distinctive techniques. Mesh refinement is performed by dividing element edges and a subsequent application of pre defined splitting templates. Mesh regularization and derefinement is achieved through topology conserving node movement (r-adaptivity). Parallel implementations of an adaptive use the dynamic load balancing technique.
Suboptimal approximations in repeatable inverse kinematics for robot manipulators
Authors: Duleba I. , Karcz-Duleba I.
Published: April 2017

In this paper a repeatable inverse kinematic task was solved via an approximation of a pseudo-inverse Jacobian matrix of a robot manipulator. An entry configuration to the task was optimized and a task-dependent definition of an approximation region, in a configuration space, was utilized. As a side effect, a relationship between manipulability and optimally augmented forward kinematics was established and independence of approximation task solutions on rotations in augmented components of kinematics was proved. A simulation study was performed on planar pendula manipulators. It was demonstrated that selection of an initial configuration to the repeatable inverse kinematic task heavily impacts solvability of the task and its quality. Some remarks on a formulation of the approximation task and its numerical aspects were also provided.
Comparative investigations of nonlinear and linear observers for a highly manoeuvrable target in sliding mode guidance
Authors: Wang Y. , Sun M. , Du S. , Chen Z.
Published: April 2017

Target manoeuvre is one of the key factors affecting guidance accuracy. To intercept highly maneuverable targets, a second-order sliding-mode guidance law, which is based on the super-twisting algorithm, is designed without depending on any information about the target motion. In the designed guidance system, the target estimator plays an essential role. Besides the existing higher-order sliding-mode observer (HOSMO), a first-order linear observer (FOLO) is also proposed to estimate the target manoeuvre, and this is the major contribution of this paper. The closed-loop guidance system can be guaranteed to be uniformly ultimately bounded (UUB) in the presence of the FOLO. The comparative simulations are carried out to investigate the overall performance resulting from these two categories of observers. The results show that the guidance law with the proposed linear observer can achieve better comprehensive criteria for the amplitude of normalised acceleration and elevator deflection requirements. The reasons for the different levels of performance of these two observer-based methods are thoroughly investigated.
Assessment of stallion semen morphology using two different staining methods, microscopic techniques, and sample sizes
Authors: Łącka Katarzyna , Kondracki Stanisław , Iwanina Maria , Wysokińska Anna
Published: April 2017

Introduction: The aim of this study was to propose the optimal methodology for stallion semen morphology analysis while taking into consideration the staining method, the microscopic techniques, and the workload generated by a number of samples. Material and Methods: Ejaculates from eight pure-bred Arabian horses were tested microscopically for the incidence of morphological defects in the spermatozoa. Two different staining methods (eosin-nigrosin and eosin-gentian dye), two different techniques of microscopic analysis (1000× and 400× magnifications), and two sample sizes (200 and 500 spermatozoa) were used. Results: Well-formed spermatozoa and those with major and minor defects according to Blom’s classification were identified. The applied staining methods gave similar results and could be used in stallion sperm morphology analysis. However, the eosin-nigrosin method was more recommendable, because it allowed to limit the number of visible artefacts without hindering the identification of protoplasm drops and enables the differentiation of living and dead spermatozoa. Conclusion: The applied microscopic techniques proved to be equally efficacious. Therefore, it is practically possible to opt for the simpler and faster 400x technique of analysing sperm morphology to examine stallion semen. We also found that the number of spermatozoa clearly affects the results of sperm morphology evaluation. Reducing the number of spermatozoa from 500 to 200 causes a decrease in the percentage of spermatozoa identified as normal and an increase in the percentage of spermatozoa determined as morphologically defective.

Introduction: The aim of this study was to investigate the influence of diet supplementation with sodium butyrate and Yucca schidigera extract (0.2% and 0.3%) on femur quality of growing pigs (n = 45). Material and Methods: At the age of 28, 35 and 56 d, five piglets from each group fed a different diet were euthanised and the femora were collected for further analyses. The bone characteristics were assessed based on weight, length, densitometric analysis of BMC and BMD, pQCT analysis (area, mineral content, volumetric density of trabecular and cortical part of metaphysis and diaphysis, respectively), ultimate strength, and geometrical parameters (cross-sectional area and second moment of inertia). Results: There were no significant differences in femur bone parameters among experimental groups on the 28th d of life. On the 35th d of life, piglets with 0.2% supplementation of sodium butyrate and Yucca schidigera extract had significantly lower values of weight and second moment of inertia, and significantly higher trabecular BMD and BMC compared to other experimental groups. In 56-day-old pigs, the higher values were observed in both experimental groups regarding BMC, ultimate strength, geometrical parameters, cortical BMC, diaphyseal total area, and endosteal circumference (P < 0.05). Significant differences between experimental groups were observed only in bone weight and cortical thickness. Conclusion: This study proved that simultaneous supplementation with sodium butyrate and Yucca schidigera extract positively influences bone quality in pigs in the post-weaning period. However, there were no differences in bone characteristics between the addition of 0.2% and 0.3% preparations.
Prediction Power Propulsion of the Ship at the Stage of Preliminary Design. Part I: Forecasting Method for Power Propulsion of Ship at the Stage of Preliminary Design
Authors: Szelangiewicz Tadeusz , Żelazny Katarzyna
Published: April 2017

During the design of the ship the most important decisions are made at the stage of preliminary design. One of the most important design parameters assumed by the shipowner is its service speed in real weather conditions occurring in the shipping line. For this speed, at the stage of preliminary design, when are known only to the basic geometric parameters of the ship and its motor power should be determined. In practice, design, power propulsion is determined with a very approximate formulas but for the speed in calm water. Only after the project contract and the signing of the contract are carried out by means of resistance and self-propulsion of model test. The article presents the concept of the method for determining the power propulsion for the assumed service speed, which depends only on the basic geometric parameters of the ship’s hull.
The Concept of Cultureme from a Lexicographical Point of View
Authors: Pamies Antonio
Published: April 2017

Culturemes can be described as extra-linguistic cultural symbols, which behave like metaphorical models, motivating figurative expressions in language (lexical or phraseological). The development of this concept in theoretical research on polysemy and phraseology shows that it can be an effective tool for organizing the representation of semantic networks of figurative meanings, according to culture-based associations of ideas.
Recent advances in “bioartificial polymeric materials” based nanovectors

Published: April 2017

This chapter analyzes the advantages of the use of bioartificial polymers as carriers and the main strategies used for their design. Despite the enormous progresses in this field, more studies are required for the fully evaluation of these nanovectors in complex organisms and for the characterization of the pharmacodynamic and pharmacokinetic of the loaded drugs. Moreover, progresses in polymer chemistry are introducing a wide range of functionalities in the bioartificial polymeric material (BPM) nanostructures leading to a second generation of bioartificial polymer therapeutics based on novel and heterogeneous architectures with higher molecular weight and predictable structures, in order to achieve greater multivalency and increased loading capacity. Therefore, research on bioartificial polymeric nanovectors is an “on-going” field capable of attracting medical interest.
CARLO MAGNO E LA SUA COLLOCAZIONE NELLA STORIA GLOBALE
Authors: Borgolte Michael
Published: April 2017

Ob das Mittelalter auch einen Platz in der neuen Globalgeschichte hat oder haben könnte, wird gegenwärtig in der internationalen Geschichtswissenschaft allenfalls für seine zweite Hälfte diskutiert. Unter den Aspekten von Reichsbildung, Migrationen und Fernhandel lässt sich die Frage auch an Karl den Großen und seine Zeit stellen. Dabei ergibt sich, dass Karl so sehr auf den Aufbau seines europäischen Reiches konzentriert war, dass er Fremden - im Unterschied zu Anderen - unter seiner Herrschaft keine Lebensräume konzedierte; wohl aber hat er im Heiligen Land die Ansiedlung von lateinischen Mönchen und Nonnen gefördert und sie damit dem Kalifat und anderen muslimischen Gewalten sowie den Aggressionen orthodoxer Griechen ausgeliefert. Mit der Förderung der Christen in Asien und Afrika gewann Karl der Großen Anschluss an die trikontinentale Ökumene der muslimischen umma; sein Motiv gründete im allgemeinen Missionsbefehl Christi, der, anders als in den Vorschriften des Islams, in der Aufforderung bestand, die Fremde geradezu zu suchen. Diese christliche Tendenz zur Grenzüberschreitung bildet aber das Urmodell noch für die Praxis der Globalisierung in unserer Gegenwart.
TRA SOVRANITÀ E IMPERIALITÀ
Authors: Ceccarelli Alessia
Published: April 2017

Die Spannung zwischen Freiheit und Reichszugehörigkeit ist eines der Kardinalthemen im frühneuzeitlichen Genua (1528-1797). Obgleich Genua wie Lucca eine formal dem Reich unterstellte Republik blieb (civitas imperialis), hatte man hier zwischenzeitlich bereits mit dem Aufbau eines eigenen Territorialstaats begonnen. Einer genuesischen Oligarchie, die dementsprechend die volle Souveränität anstrebte, stand der Kaiserhof gegenüber, der diesen Prozeß zu verhindern suchte und Genua keine größeren Freiheiten gewähren wollte als den deutschen Reichsstädten. Die erste Hälfte des 17. Jahrhunderts, vor allem der Zeitraum zwischen 1623 und 1627, bildete den Höhepunkt dieses Konflikts, denn ein Teil der genuesischen Bürgerschaft, d.h. eine neue kämpferische Faktion des Popolo (Popolo grasso: Kaufleute, Ärzte, sollecitatori di liti …) vertrat im Kampf um die Macht zum ersten Mal die Positionen des Reiches (Reichszugehörigkeit versus Souveränität). Tatsächlich hatten zunächst Andrea Doria (1528), dann die leges novae (1576) nicht nur die politischen Prärogativen dieses Popolo abgeschafft, sondern auch sein Bild zerstört (ein Popolo, das nicht regiert). Um ihre Ziele zu erreichen, zögerte die Faktion nicht, einen erbitterten politischen Kampf zu entfesseln (Verschwörungen Ansaldi-Vachero 1627/28 und Ligalupo 1629/30) und um Unterstützung bei fremden Fürsten wie Karl Emanuel I. von Savoyen, Herzog von Piemont, und sogar in Spanien nachzusuchen. Einen besonderen Aspekt in dieser Auseinandersetzung stellte der ebenfalls von unten initiierte Krieg der Schriften (Krieg im Krieg) dar. Zum ersten Mal wurden die Schmähschriften, di Ragguagli di Parnaso (politische Satiren nach dem Modell Traino Boccalinis) und politischen Manifeste des genuesischen Popolo gedruckt und auch außerhalb Liguriens verbreitet. Die Antworten der Oligarchie hingegen, welche die alleinige Trägerin der politischen Macht blieb, sind noch heute handschriftlich erhalten und bilden einen der zahlreichen wertvollen Bestände der öffentlichen Archive in Genua.
GENTILE STEFANESCHI ROMANO O. P. (†1303) O GENTILE ORSINI?
Authors: Leonardi Marco , Schwarz Brigide
Published: April 2017

Die Atmosphäre großer politischer Instabilität, die in Sizilien am Ende des 13. und zu Beginn des 14. Jh. herrschte, erfährt in den politischen Ereignissen, die in dieser Phase die Stadt Catania betrafen, eine charakteristische Verdichtung. Die Stadt am Ätna, die zunächst unter der Herrschaft des Rex Trinacriae Friedrich III. von Aragon (1296-1298), dann aufgrund einer Verschwörung auf Seiten Roberts von Anjou (1299-1302) stand und danach unter die Kontrolle der Aragonesen zurückkehrte (März 1302), spielte durch ihre geografische Lage begünstigt eine Hauptrolle auf dem politischen Schachbrett des Mittelmeerraums. Der Kampf um die Kontrolle über die Stadt wurde aber nicht allein mit Waffengewalt ausgefochten: die Ernennung des Dominikanerbruders Gentile Romano zum Bischof von Catania in der zweiten Hälfte des Jahres 1296 durch Bonifaz VIII. erwies sich als ein vom Papsttum unternommener Versuch, die einheimische Bevölkerung zur Unterstützung der den päpstlichen Weisungen folgenden Anjou zu veranlassen - zum Nachteil der auf der Insel verbliebenen Aragonesen. Doch wer war dieser Gentile Romano, den die zeitgenössischen Quellen als einen geschickten Diplomaten und Vermittler zeichnen? Und vor allem, wie kommt es, dass ein Mann von seiner Bedeutung, der zudem bekanntermaßen von 1292 bis 1293 an der Universität Paris gelehrt hat, in den zeitgenössischen Quellen als Gentilis Romanus oder Gentilis de Stefaneschis Romanus bezeichnet, aber vom 16. Jh. an bis heute als Gentile Orsini geführt wird? Anhand unedierter archivalischer Quellen und historiografischer Werke, die vom Beginn der Neuzeit bis heute ihr Wissen über den Dominikanerbischof einander weiterreichten, rekonstruiert der Verfasser das Wirken des Gentile Stefaneschi Romanus. Gestützt auf die unedierten Quellen und auf eine kritische Überprüfung der Entwicklungphasen, in denen sich im Laufe der Jahrhunderte die matronymische Zubenennung verfestigte, durchleuchtet der Aufsatz das tiefe, bisweilen unentwirrbare Geflecht, durch das der ungewöhnliche Lebenslauf eines Vertreters zweier adeliger Familien des spätmittelalterlichen Rom, die Folgen der kurialen Politik für die Veränderungen der politischen Balance im insularen Teil des Königreichs und die Verfestigung der - jedenfalls für süditalienische Werke der Neuzeit ungewöhnlichen - Namensbezeichnung nach der mütterlichen Familie miteinander verflochten sind.
Preconditioners with projectors for mixed hybrid finite element methods
Authors: Kuznetsov Yuri A. , Kramarenko Vasily K.
Published: April 2017

We propose and investigate numerically two new preconditioners for the matrices, which arise in the mixed-hybrid finite element methods for diffusion equation in strongly heterogeneous media. Both preconditioners include special projectors on the vector spaces orthogonal to the vectors with constant components. We give general description of the preconditioners and discuss numerical results which demonstrate their efficiency compared to the classical diagonal preconditioner.
Impact of Globalisation On Economic Growth in Romania: An Empirical Analysis of Its Economic, Social and Political Dimensions
Authors: Olimpia Neagu , Stela Dima
Published: April 2017

The paper analyses the link between globalisation and economic growth in Romania for a time span of 24 years. Data from World Bank were used in an econometrical model in order to highlight the impact of globalisation, expressed by the KOF globalisation index and its components (economic, social and political globalisation indices) on economic growth rate. A statistical strong and positive link is found between GDP per capita dynamics and overall globalisation index as well as between GDP growth rate and economic and political globalisation, except the social dimension of globalisation which has a negative impact on economic growth in Romania for the time span 1990-2013.
Hockey im Club oder Skaten im Park?

Published: April 2017

Während die Bedingungsfaktoren der generellen Sportaktivität und der Sportvereinsaktivität für die Adoleszenz gut belegt sind, werden andere Settings wie das informelle Sporttreiben nur vereinzelt explizit betrachtet. Der Beitrag greift dies auf und analysiert die Sozialisationsbedingungen für die Teilnahme am informellen und vereinsorganisierten Sport. In Anlehnung an die interaktionale Sozialisationstheorie werden die soziale Lage, personale und soziale Ressourcen als sozialisationsrelevante Dimensionen fokussiert. Gesellschaftliche Mediatisierungsprozesse und die Bedeutungszunahme von Aktivitäten in und mit sozialen Medien führen zudem zur Berücksichtigung medialer Ressourcen. Mittels binärer Regressionsmodelle werden in dieser Sekundäranalyse der MediKuS-Studie (DJI) die Sozialisationsbedingungen für den informellen und vereinsorganisierten Sport analysiert.

Mein Besonderer Dank gilt dem Deutschen Jugendinstitut (DJI) und dem Deutschen Internationalen Institut für Pädagogische Forschung (DIPF) für die Möglichkeit die Daten der ‚Medien, Kultur und Sport’-Studie für Sekundärdatenanalysen im Rahmen meines Promotionsvorhabens zu nutzen.
