Development, demographic transition and net migration: evidence for the municipalities of Mexico, 2000-2010
Authors: Peláez-Herreros Óscar
Published: October 2017

In this paper we review and integrate into a single analytical framework the theoretical approaches that explain the connection of the development process with natural population growth, migration and income inequality. Also, we provide evidence of the direction and intensity of these relations for the case of Mexico. With this purpose, we estimate the net migration rate of the 2,443 municipalities of the country during the period 2000-2010, finding that higher levels of development correspond to lower rates of natural population growth and with lower rates of emigration. We find no evidence of a hypothetical positive relationship between emigration and inequality, and doubt about that income inequality increases at the beginning of the development process and then decline. In any case, the detected relationships are weak, suggesting that some specific factors are left out of the analysis.
José Luis Sampedro (1917-2013), pionero de los Estudios del Desarrollo
Authors: Domínguez-Martín Rafael
Published: October 2017

Como otros pioneros del desarrollo, Sampedro se familiarizó con esta área de conocimiento abordando el problema colonial. También como ellos combinó la academia (en 1951 obtuvo el grado de doctor con Premio Extraordinario y en 1955 consiguió la primera cátedra de Estructura Económica) con puestos de responsabilidad técnica (de humilde funcionario de aduanas pasó a colaborar en la elaboración de las tablas input-output y la contabilidad nacional de España, para luego participar en varias negociaciones internacionales como asesor de los Ministerios de Comercio y Hacienda y del Banco Exterior de España). Asimismo, como los otros pioneros, recibió el impacto de Keynes (a quien consideraba responsable de la recuperación de la Economía política como ciencia social), y se nutrió de las teorías disidentes (primero de institucionalistas, marxistas y estructuralistas franceses, y luego de estructuralistas y dependentistas latinoamericanos y críticos ambientalistas) que reclamaban la vuelta de la Economía a la solución de los problemas esenciales (la pobreza, las desigualdades y los bienes públicos globales) desde una perspectiva interdisciplinar. CITE AS:Domínguez-Martín, R.

The Favelas of Rio de Janeiro: A study of socio-spatial segregation and racial discrimination
Authors: Olavarria-Berenguer Leticia
Published: October 2017

Race relations in Brazil are characterized by the coexistence of miscegenation (interracial social contact) and racial discrimination. This paper examines to what extent Brazilian race relations are expressed in the urban space, how they inflect its physical configuration and influence the social processes that take place within it. In this sense, it states that as long as it is considered that the space is subjected to power relations it can be asserted that these dynamics are expressed in the configuration of Brazilian cities, particularly in Rio de Janeiro. Thus, the urban structure of Rio reflects certain level of interracial sociability in terms of residence and the social hyper-inequalities of Brazilian society. In addition, the study of the favelas shows how discourses about race and urban space are interconnected and reinforce racial discrimination.CITE AS:Olavarria-Berenguer, L. (2014).

La ciudad en el futurismo italiano (1909-1915) | Cities in italian futurism (1909-1915)
Authors: Pizza Antonio
Published: October 2017

El 20 de Febrero de 1909 aparece en primera página en Le Figaro, como anuncio pagado, el auténtico punto de arranque del movimiento: el texto “Le Futurisme”, firmado por Marinetti. En la ciudad futurista no se detectan presencias humanas y sobretodo faltan las masas urbanas; justamente aquellas muchedumbres ondeantes y enardecidas, glosadas por los pintores futuristas que además, en sus cuadros, retrataban los cascos antiguos o las primeras periferias proletarias existentes en Italia.On 20th February 1909 the real starting point of the movement was published on the front page of LeFigaro, in the text “Le Futurisme” signed by Marinetti. In the futurist city no human presence is detected and theurban masses are particularly conspicuous by their absence; precisely those pulsating, bustling crowds depictedby the futurist painters whose paintings portrayed the ancient city centres of the first proletarian suburbs thatexisted in Italy.
Gordon Cullen y The Architectural Review: ideas no construidas para Marlow New Town | Gordon Cullen and The Architectural Review: unbuilt ideas for Marlow New Town
Authors: Montes Carlos
Published: October 2017

Tratar de las ideas de Gordon Cullen en la década de los cincuenta, nos remite a sus artículos en la revista The Architectural Review y a la campaña orquestada por sus editores en defensa de las ideas del Townscape aplicadas al diseño urbano y a los New Towns. Los artículos de Cullen incluían siempre dibujos magistrales con los que conseguía sintetizar y transmitir a sus lectores sus conceptos, no siempre fáciles de exponer por escrito. En el presente ensayo analizamos su propuesta gráfica de un posible New Town situado en un meandro del río Támesis, junto a la pequeña localidad de Marlow, idea no construida con la que Gordon Cullen pretendía ofrecer en 1950 una alternativa al urbanismo y a la arquitectura de los New Towns que se estaban creando en la campiña inglesa.Dealing with Gordon Cullen’s ideas in the decade of the fifties refers us to his articles in the magazine “The Architectural Review” and the campaign orchestrated by its publishers to defend the ideas of Townscape applied to urban design and New Towns. The articles by Cullen always included masterful drawings through which he managed to synthesise and transmit his concepts to the readers, which were not always easy to describe in words. This paper analyses his graphic proposal for a possible New Town located on a meander of the River Thames, next to the small town of Marlow. This idea was never actually built, although Gordon Cullen tried to put forward an alternative to urbanism in 1950 and the architecture of New Towns that were being created in the English countryside.
Mahnmale y living memorials en la reconstrucción francesa de posguerra | Mahnmale and living memorials in postwar French reconstruction
Authors: Molina Mariano
Published: October 2017

El artículo explora los casos de Oradour-sur-Glane y Saint-Dié (particularmente el proyecto de reconstrucción no ejecutado de Le Corbusier para la segunda ciudad) como representativos de las fracturas sociales que produjo en Francia la Segunda Guerra Mundial y exponentes de dos estrategias conmemorativas habituales de la época: el monumento de advertencia o Mahnmal y el equipamiento cívico o living memorial. Finalmente trata de explicar el devenir de cada caso desde la idea del espacio urbano como “marco social” de la memoria colectiva, introducida por el sociólogo francés Maurice Halbwachs, y desde la construcción de la historia allí donde la memoria desaparece. En el caso de Saint-Dié, si bien la profunda transformación del tejido urbano y las reticencias estilísticas de la población fueron importantes, el desinterés de Le Corbusier por recrear en el centro cívico los rasgos más relevantes de la ciudad previa frustró su objetivo de convertir esta área central en depositaria de la identidad de la población.This article explores the cases of Oradour-sur-Glane and Saint-Dié (particularly the unbuilt project by Le Corbusier for the latter) as representative of the social fractures that took place in France after World War II, and examples of two memorial strategies that became popular at that moment: the “warning monument” or Mahnmal and the civic facility or living memorial. Ultimately, it attempts to explain the fate of each of them based on the idea of urban space as “social frame” of collective memory, introduced by the French sociologist Maurice Halbwachs, and on the construction of history at the point where memory vanishes. In the case of Saint-Dié, while the profound transformation of the urban fabric and the stylistic reluctance of the population were both important, Le Corbusier’s lack of interest in recreating in his civic center the most significant features of the previous city thwarted his goal of making this central area the repository of the identity of the population.
Proyectos en torno al convento de San Francisco el Grande de Madrid: incertidumbres urbanísticas e indefinición paisajística | Projects concerning the convent of San Francisco el Grande in Madrid: urban uncertainty and landscaping indefinition
Authors: Jiménez Benito
Published: October 2017

La tradición ha hecho de la llamada Cornisa oeste de Madrid su imagen más definitoria y distintiva. El Palacio Real y el colindante convento de San Francisco el Grande son sus elementos patrimoniales más significativos. Previa a su desamortización y posterior demolición, el convento ocupaba una vasta extensión de terreno, formada por huertas, patios y claustros ajardinados, que se distribuían de manera orgánica en terrazas descendentes hacia el río Manzanares. En la actualidad un gran vacío rodea su basílica, el único vestigio conventual. Desde el siglo XIX varias controvertidas propuestas han tratado de caracterizar y revitalizar ese espacio indefinido, regenerar su degradado entorno y dar así continuidad paisajística a la Cornisa. El presente estudio pretende valorar la evolución del entorno del convento, intentando explicar el porqué de esa especie de no-lugar, mediante la comparación y revisión de la cartografía histórica, las representaciones existentes y los diferentes proyectos de intervención planteados en la zona.The tradition has made the so-named west Cornice of Madrid the most defining and distinctive image of the city. The Royal Palace and the nearby Convent of San Francisco el Grande are its most significant heritage elements. Before its confiscation and subsequent partial demolition, the convent occupied a vast extension of land, formed by orchards, patios and gardened cloisters, organically distributed on terraces descending towards the River Manzanares. Nowadays, a large empty space encircles the Basilica, which is the only remaining convent vestige. From the 19th Century onwards, several controversial proposals aimed to characterize and revitalize this undefined space, regenerate its deteriorated surroundings and thus provide landscaping continuity to the fragmented Cornice. The present study attempts to assess the evolution of the convent environment and explain the reason of this “no-place” by comparing and reviewing historical cartography, existing representations and the different intervention projects proposed for the area.

Cuatro iniciativas de agricultura en la ciudad frente a la banalización del paisaje histórico urbano | Four urban agriculture initiatives against the banalization of urban historical landscape
Authors: Arredondo Garrido David
Published: October 2017

En ciudades con un importante patrimonio histórico son cada vez más frecuentes los procesos de homogeneización del paisaje urbano. Una dinámica que conduce a la transformación de determinados entornos históricos en espacios en donde apenas queda lugar para la singularidad, las actividades no reguladas o la participación ciudadana. Este estudio propone analizar una serie de iniciativas desarrolladas en la última década en centros de cuatro ciudades españolas, concretamente en Sevilla, Barcelona, Madrid y Zaragoza. Proyectos que se apoyan en la agricultura y la jardinería urbanas para sortear la banalización imperante, creando espacios para la cultura, las relaciones sociales y la imaginación. Pese a las dificultades en su gestión y su repercusión minoritaria, estas intervenciones ejemplifican un modo de reconfigurar el paisaje urbano, planteando esquemas de activación, percepción activa y participación en lugares centrales de la ciudad en proceso de abandono, donde las actividades agrícolas y jardineras adquieren un peso importante.PALABRAS CLAVE: paisaje urbano, acupuntura urbana, agricultura urbana, participación ciudadana, derecho a la ciudad.Processes of homogenization of the urban landscape are becoming more frequent in cities with an important historical heritage. A dynamic that leads to the transformation of certain historical environments in spaces where there is hardly any room for uniqueness, unregulated activities or public participation. This study aims to analyse a number of initiatives developed in the last decade in four Spanish city centres, particularly in Seville, Barcelona, Madrid and Zaragoza. Projects that are using urban agriculture and gardening to escape form current banality, creating spaces for culture, social relations and imagination. Despite the difficulties in its management and its minor impact, these interventions exemplify a way to reshape urban landscape, through schemes of activation, active perception and participation in abandoned places in the city, where agricultural activities and gardening are now playing an important role.KEYWORDS: urban landscape, urban acupuncture, urban agriculture, citizen participation, right to the city.

Weather affects temporal niche partitioning between moose and livestock
Authors: Herfindal Ivar , Lande Unni Støbet , Solberg Erling Johan , Rolandsen Christer Moe , Roer Ole , Wam Hilde Karine
Published: October 2017

Co‐existing species at the same trophic level often segregate with respect to diet, habitat use, or spatial distribution, reducing their direct competition for resources. However, temporal patterns in species‐specific habitat use, for instance due to climatic variation, may affect the strength of interspecific interactions, and generate temporal variation in niche partitioning. We assessed temporal variation in habitat overlap between a wild ungulate, mooseAlces alces, and two freeranging domestic ungulates, sheepOvis ariesand cattleBos taurus, on a boreal forest range in southern Norway. We also calculated the distance between species' realised niches, as well as the width of their realised niches to evaluate the extent of temporal niche partitioning under different diurnal weather conditions. Analyses of each habitat variable suggested complex relationships between species‐specific habitat use, photoperiod, and weather, related to species‐specific behaviour and activity patterns. We found shorter overall niche distance between moose and sheep, compared to moose and cattle, and shorter niche distances during day and night than during the twilight hours. The niche distance between moose and sheep was positively related to temperature during night, but negatively during day. Moreover, niche distance between moose and both sheep and cattle was negatively related to precipitation at daytime. Moose niche width was narrower in periods with short niche distance to sheep, while we did not find such pattern towards cattle. A lack of similar moose response to cattle could be attributed to lower niche overlap between moose and cattle. Our results suggest that temporal niche partitioning between moose and livestock breaks down under the weather conditions that are predicted to become more common as climate change, potentially increasing wildlife‐livestock interactions in the future.
Anglicisms and Students in Quebec: Oral, Written, Public, and Private—Do Personal Opinions on Language Protection Influence Students' Use of English Borrowings?
Authors: Planchon Cécile , Stockemer Daniel
Published: October 2017

What is the influence of students' assessment of the official language protection regime in Quebec and their usage of English borrowings in oral and written language, as well as in the private and public spheres? Hypothesizing that survey participants, who deem Bill 101 and the language protection policy as too lax, use fewer English borrowings in any setting than do students who deem the policy to be adequate or too strong, we evaluate students' usage of five of the most frequent English borrowings found in three newspapers of the Canadian francophone written press in 2014, namely coach, condo, fun, look, and performer. With the help of a large-scale survey conducted in various universities in the Province of Quebec and the national capital region of Canada and using various quantitative techniques, we find that there is a difference in the students' usage of anglicisms between the oral and the written language and between the private and the public realms. However, we do not find any major differences in the usage of the five borrowings in any of the two domains (i.e., oral vs. written and private vs. public) between students who advocate a stricter language policy and students favouring a laxer language policy.
Synthesis and characterization of mechanically alloyed cerium oxide reinforced Al-4.5Mg alloy composite
Authors: Rastgarnia Sara , Ranjbar Khalil , Gheisari Khalil O. , Borhani Gholam H.
Published: October 2017

Al-4.5Mg-0.5Mn alloy powders were mechanically alloyed by the addition of 1–3 wt.% cerium oxide (CeO2) nanoparticles using a planetary ball mill under a dry argon atmosphere. A milling speed of 300 rpm and ball to powder ratio of 20:1 was used for all samples. An optimum milling time of 20 h was chosen considering the morphological and structural changes in the milled powders. The composite powders were consolidated via vacuum hot pressing at 515°C. Mechanical properties were evaluated by hardness and compression tests. The evolution of the structure and microstructure during the milling process was studied using X-ray diffraction and field emission scanning electron microscopy, respectively. The corrosion behavior of the samples was investigated by potentiodynamic polarization testing in a standard 3.5% chloride salt solution and assessed in terms of pitting potential and passivation range. CeO2 reinforced mechanically alloyed Al-4.5Mg exhibited a major improvement in its hardness and compressive strength compared to the un-reinforced base alloy, i.e. 40 and 50% increment respectively. Nevertheless, the most important effect of CeO2 incorporation was observed in the pitting resistance of the alloy.
Current Issues in Highway–Rail Grade Crossing Hazard-Ranking and Project Development
Authors: Sperry Benjamin R. , Naik Bhaven , Warner Jeffery E.
Published: October 2017

This paper reports on a comprehensive research study of hazard-ranking models for prioritization and selection of highway–rail grade crossing improvement projects. The U.S. Department of Transportation (DOT) accident prediction model is the most commonly used hazard-ranking model, although 11 states use state-specific models. Key variables not included in the U.S. DOT model but included in state-specific models may provide useful insight for identifying hazardous crossing locations. Emerging issues, such as the crash modeling approach used by the U.S. DOT model and the application of economic analysis principles in project prioritization, are also discussed. The findings reported in this paper provide a starting point for a broader discussion among all stakeholders in the grade crossing safety community about ways to improve hazard-ranking and project selection for highway–rail grade crossing investments.

The risk methodology accounted for FRA track class, method of operation, annual traffic density, train length, speed, point of derailment, the number and placement of tank cars in a train, tank car placement, tank car safety design, and population density along the rail line. With these inputs, the methodology estimates train derailment rate, the probability of tank car derailment and release, and release consequence by train configuration. The analysis showed that tank car positions could affect the risk comparison between unit trains and mixed trains in transporting hazardous materials. In particular, if all tank cars were in positions that were least prone to derailment, distributing tank cars to many unit trains could reduce the overall risk. Otherwise, consolidating tank cars into unit trains could lead to a lower risk. The methodology has been implemented in a computer-aided decision support tool that automatically calculates the risk values for various track, rolling stock, and operational characteristics.

Even though the Barn Owl ( Tyto alba) is distributed worldwide, little information is available on how weather affects Barn Owl breeding outside of Europe and North America. For instance, if cold temperatures can negatively influence population dynamics in temperate regions, heat could have a similar negative effect in arid regions. We have studied a breeding population of Barn Owls in a semi-arid agricultural environment over 13 years in Israel in order to determine whether lack of rain and hot ambient temperatures impair Barn Owl reproductive success. The percentage of nest boxes occupied by Barn Owls was not related to any of the weather variables, whereas the number of nestlings per Barn Owl pair and the percentage of pairs that succeeded to fledge young was lower in years when it started to rain later in the season and when the minimum daily temperature was higher during the breeding season. In comparison to temperate regions, heat is detrimental to Barn Owl breeding and early precipitation is probably important in boosting vegetation and, in turn, the abundance of small mammals, the Barn Owl's staple food.

Nuptial plumage colouration is seemingly favoured by females of avian species with regards to sexual selection. This particular secondary sexual characteristic has been previously shown to be a condition-dependent signal of individual quality among passerines with pigment-based colouration (i.e. yellows and reds). In contrast, relationships between structural plumage colouration (i.e. blues) and aspects of both physical quality and physiological function have been understudied. Using free-living Indigo Buntings (Passerina cyanea) as a study species, we compared the percentage of blue feather coverage to body condition, innate immune responses, antioxidant capacity, stress physiology, reproductive physiology, and parasitism. We found the overall percentage of blue feathers on individual birds to be positively correlated with testosterone levels and body condition, while negatively correlated with heterophil to lymphocyte ratio. Birds with more blue coverage were also less likely to harbour blood parasites. Our results indicate male Indigo Buntings with greater moult investment have better overall body condition, lower stress, increased testosterone levels, and decreased parasitic susceptibility.

Published: October 2017

This paper aims to evaluate the influence of the microwave heating time on the self-healing properties of fibre-reinforced asphalt mixtures. To this purpose, self-healing properties of dense asphalt mixtures with four different percentages of steel wool fibres were evaluated as the three-point bending strength before and after healing via microwave heating at four different heating times. Furthermore, the thermal behaviour of asphalt mixtures during microwave heating was also evaluated. With the aim of quantifying the efficiency of the repair process, ten damage-healing cycles were done in the test samples. In addition, self-healing results were compared with the fibre spatial distribution inside asphalt samples evaluated by CT-scans. Crack-size change on asphalt samples during healing cycles was also evaluated through optical microscopy. It was found that the heating time is the most influential variable on the healing level reached by the asphalt mixtures tested by microwave radiation. CT-Scans results proved that fibre spatial distribution into the asphalt mixtures play an important role in the asphalt healing level. Finally, it was concluded that 40 s was the optimum heating time to reach the highest healing levels with the lowest damage on the asphalt samples, and that heating times over 30 s can seal the cracks, thus achieving the self-healing of asphalt mixtures via microwave heating.

This study aims to design and develop the prototype models of the smart photovoltaic system blind (SPSB). To achieve this objective, the study defined the properties in three ways: (i) the photovoltaic (PV) panel; (ii) the tracking system; and (iii) the monitoring system. First, the amorphous silicon PV panel was determined as a PV panel, and the width and length of the PV panel were determined to be 50 mm and 250 mm, respectively. Second, the four tracker types (i.e., fixed type, vertical single-axis tracker, horizontal single-axis tracker, and azimuth-altitude dual-axis tracker) was applied, as well as the direct tracking method based on the amount of electricity generated as a tracking system. Third, the electricity generation and environmental conditions were chosen as factors to be monitored in order to evaluate and manage the technical performance of SPSB as a monitoring system. The prototype model of the SPSB is designed and developed for providing the electricity generated from its PV panel, as well as for reducing the indoor cooling demands through the blind’s function, itself (i.e., blocking out sunlight).

Published: October 2017

This paper presents the application of the Coupled Eulerian–Lagrangian (CEL) technique on the constructability problems of site on very soft soil. The main objective of this study was to investigate the constructability and application of two ground improvement methods, such as the forced replacement method and the deep mixing method. The comparison between the results of CEL analyses and field investigations was performed to verify the CEL modelling. The behavior of very soft soil and constructability with methods can be appropriately investigated using the CEL technique, which would be useful tools for comprehensive reviews in preliminary design.

Any network connected to the Internet is subject to cyber attacks. Strong security measures, forensic tools, and investigators contribute together to detect and mitigate those attacks, reducing the damages and enabling reestablishing the network to its normal operation, thus increasing the cybersecurity of the networked environment. This paper addresses the use of a forensic approach with Deep Packet Inspection to detect anomalies in the network traffic. As cyber attacks may occur on any layer of the TCP/IP networking model, Deep Packet Inspection is an effective way to reveal suspicious content in the headers or the payloads in any packet processing layer, excepting of course situations where the payload is encrypted. Although being efficient, this technique still faces big challenges. The contributions of this paper rely on the association of Deep Packet Inspection with forensics analysis to evaluate different attacks towards a Honeynet operating in a network laboratory at the University of Brasilia. In this perspective, this work could identify and map the content and behavior of attacks such as the Mirai botnet and brute-force attacks targeting various different network services. Obtained results demonstrate the behavior of automated attacks (such as worms and bots) and non-automated attacks (brute-force conducted with different tools). The data collected and analyzed is then used to generate statistics of used usernames and passwords, IP and services distribution, among other elements. This paper also discusses the importance of network forensics and Chain of Custody procedures to conduct investigations and shows the effectiveness of the mentioned techniques in evaluating different attacks in networks.

We previously identified a novel apoptosis-inducing humoral factor in the conditioned medium of hypoxic/reoxygenated-cardiac myocytes. We named this novel post-translationally-modified secreted-form of eukaryotic translation initiation factor 5A Oxidative stress-Responsive Apoptosis-Inducing Protein (ORAIP). We confirmed that myocardial ischemia/reperfusion markedly increased plasma ORAIP levels and rat myocardial ischemia/reperfusion injury was clearly suppressed by neutralizing anti-ORAIP monoclonal antibodies (mAbs) in vivo. In this study, to investigate the mechanism of cell injury of cardiac myocytes and pancreatic β-cells involved in diabetes mellitus (DM), we analyzed plasma ORAIP levels in DM model rats and the role of ORAIP in high glucose-induced apoptosis of cardiac myocytes in vitro. We also examined whether recombinant-ORAIP induces apoptosis in pancreatic β-cells. Plasma ORAIP levels in DM rats during diabetic phase were about 18 times elevated as compared with non-diabetic phase. High glucose induced massive apoptosis in cardiac myocytes (66.2 ± 2.2%), which was 78% suppressed by neutralizing anti-ORAIP mAb in vitro. Furthermore, recombinant-ORAIP clearly induced apoptosis in pancreatic β-cells in vitro. These findings strongly suggested that ORAIP plays a pivotal role in hyperglycemia-induced myocardial injury and pancreatic β-cell injury in DM. ORAIP will be a biomarker and a critical therapeutic target for cardiac injury and progression of DM itself.
