Estilos parentales y resultados de la socialización familiar a corto y largo plazo: un estudio con adolescentes y adultos mayores españoles
2018
ABSTRACT In this study, the association between parenting styles and short- and long-term socialization outcomes was analyzed using a two-dimensional model of four types of parenting styles. The socialization outcomes analyzed were self-esteem and internalization of social values. Participants were a sample of Spanish adolescents (n = 571) and older adults (n = 527). Results showed that both adolescents and older adults from indulgent families reported equal or even higher self-esteem than those from authoritative households, whereas those from neglectful and authoritarian homes were consistently associated with the lowest levels of self-esteem. Regarding internalization of social values, a…

Tecnología de biorreactores anaerobios de membrana (AnMBR) para tratamiento de aguas residuales urbanas y reutilización de agua en agricultura. Una s…
2018
La combinación de la tecnología de biorreactores anaerobios de membrana (AnMBR, por sus siglas en inglés) para el tratamiento de aguas residuales y la reutilización de su efluente en agricultura da como resultado un concepto más sostenible para la depuración, donde las aguas residuales se convierten en una fuente de energía (biogás) y nutrientes (nitrógeno y fósforo) a la vez que se genera un recurso alternativo de agua que puede ayudar a paliar la escasez a la que nos enfrentamos a nivel global. Sin embargo, para aprovechar los beneficios del agua regenerada y los recursos recuperados de las aguas residuales se necesitan políticas inteligentes que brinden flexibilidad para la implementació…

Encuentros y desencuentros de la Antigüedad tardía con la Edad Media en el "Libro de Apolonio"
2018
El Libro de Apolonio es un poema compuesto seguramente hacia 1240, conservado en una única copia de la segunda mitad del siglo XIV, y basado en un texto latino, la Historia Apollonii regis Tyri, quizá procedente de otro griego, que se origina en los primeros siglos de nuestra era, adquiere cierta forma en los siglos V o VI, y se sigue transmitiendo y modificando a lo largo de la Edad Media. El artí-culo estudia algunos encuentros y desencuentros de la Antigüedad tardía con la Edad Media que revelan las distintas capas textuales presentes en el Libro de Apolonio, fundamentalmente en lo que se refiere a su encaje literario, especialmente genérico, y al modo de presentar la «cortesía» como mat…

This study focuses on the evolution of multilingualism from a linguistics of communitiy to a linguistics of contact till a linguistics of global societies.The growing international interest in multilingualism, which has been marked by the changing political and economic landscape of different nations in the world, is significantly represented in the media and in public discourse. Globalization, transnational population flows and the spread of new technological platforms have given rise to remarkable linguistic, cultural and demographic transformations, still occurring in the globe. The burgeoning research in bilingualism and multilingualism, which covers a broad range of specific domains fr…
Disentangling directional and fluctuating asymmetry in a genome-wide association study.
2018
8 pages; International audience; Although directional and fluctuating asymmetry have been frequently assessed independently, they are indeed associated concepts both in theory and in practice. However, they can be difficult to disentangle in genome-wide association studies, where the appropriate shape statistics are not fully developed. Although the usage of Procrustes distances to overcome this problem may be tempting, this does not reliably help to identify the underlying genetic components of directional and fluctuating asymmetries. Here, similarities and differences among different approaches have revealed that the genetic component of the skull asymmetry in this population of mice is m…
Ciudades literarias y espacios públicos creativos. Un análisis de poesía callejera en Latinoamérica y Europa
2018
El presente artículo plantea un análisis de la poesía callejera (como una expresión grafitera) en Latinoamérica y Europa. El objetivo principal es discutir cómo esta forma de intervención poética en el espacio público es constructora de diálogos con el habitante de la ciudad, es decir, como una herramienta que provoca una reflexión en el espacio urbano hacia la constitución de nuevos espacios públicos compartidos. Para ello, como línea estructurante, el artículo se divide en tres bloques: i) las relaciones que se generan en la ciudad con referencia a la poesía callejera y el habitante; ii) el lugar del artivismo (conjunción entre el arte callejero y el activismo político-social) como expres…

Verificación de las huellas dactilares fraudulentas en 3D
2018
En el año 2008 aparece Microlo foscopia * , en cuyo trabajo se pone de manifiesto la problemática sobre la reproducción fraudulenta de huellas artificiales; al mismo tiempo muestra sus diferencias, replantea y justifica nuevas significaciones al referirse a este análisis. El primer conce pto que requiere ser modificado, según el precitado texto, y coherente con su sentido, es la palabra ? artificial ?, aplicada como contraria a ?natural?, sus acepciones las define la Real Academia Española como: ?1. adj. Hecho por mano o arte del hombre. 2. adj. No natural, falso. 3. adj. Producido por el ingenio humano. 4. adj. desus. Disimulado, cauteloso?. Este término, se emplea por los peritos de Docum…
Audience expectations and trust in online journalism
2018
Audience trust towards journalism gives meaning to the work of journalists. Yet this trust is in decline, which is threatening both media businesses and the society at large. This development is the worrisome but still natural result of trust’s intrinsic qualities. Trust is context-dependent: different situations evoke different expectations, the fulfilment of which defines what is “worthy of trust”. Changes to the journalistic environment shift audience expectations and thus disrupt the existing trust. The Internet and the introduction of online journalism are major drivers of such change. In light of these changes we can ask: what does the audience expect from online journalism? This arti…
La construcción del territorio a través del ciberespacio: una mirada latinoamericana de la percepción de los jóvenes frente al espacio virtual
2018
El trabajo parte del problema de comprender la sensación de movilidad espacial y la ruptura de un espacio vivido como algo físico e inmediato que genera nuevos desafíos en el aprendizaje, tanto de los jóvenes colombianos, como de otros lugares de América Latina y el mundo. Éllos se abren a una sociedad global sin capacidad de analizar su funcionamiento, exponiéndose al arbitrio de decisiones emanadas de lugares lejanos y que le afectan en su comprensión del mundo vivido. De aquí que se quiera preguntar por ¿Cómo se pueden comprender las nuevas formas de representación del territorio en el ciberespacio desde la visión de los jóvenes de colegios públicos y privados en Villavicencio – Colombia…

El Uso de valoraciones del riesgo de violencia en Derecho Penal: algunas cautelas necesarias
2018
La valoración del riesgo de violencia o de reincidencia con herramientas estructuradas, que cada vez está más presente en el ámbito de la justicia penal, es un procedimiento complejo, y para comprender correctamente sus resultados es necesario un conocimiento mínimo de algunos conceptos estadísticos. La forma en que usualmente se presenta en la literatura criminológica especializada la información sobre la capacidad de estas herramientas para predecir con acierto el riesgo de violencia no favorece una correcta interpretación de su alcance, pues se tiende a destacar aquellos aspectos en que estas herramientas funcionan mejor, y a subrayar mucho menos aquéllos otros en que sus resultados son …
Time and Performance Pressure
2018
Abstract. Time pressure and performance pressure are among the most crucial job demands of today’s workforce. However, the literature on psychological stress barely distinguishes between these constructs. Therefore, we aimed to examine time pressure and performance pressure as two qualitatively different job demands in terms of unique moderators for both demands. We investigated whether time control would moderate the relationship between time pressure and both emotional exhaustion and work engagement. As a vulnerability factor for dealing with performance pressure, we investigated perfectionism. The cross-sectional data of 167 employees showed that time control was a significant moderator…
Applications of Chemoinformatics in Predictive Toxicology for Regulatory Purposes, Especially in the Context of the EU REACH Legislation
2018
Chemoinformatics methodologies such as QSAR/QSPR have been used for decades in drug discovery projects, especially for the finding of new compounds with therapeutic properties and the optimization of ADME properties on chemical series. The application of computational techniques in predictive toxicology is much more recent, and they are experiencing an increasingly interest because of the new legal requirements imposed by national and international regulations. In the pharmaceutical field, the US Food and Drug Administration (FDA) support the use of predictive models for regulatory decision-making when assessing the genotoxic and carcinogenic potential of drug impurities. In Europe, the REA…
Historical Part—Calculus of Variations

Here, we briefly introduce the reader to the main results.
Stock Earnings and Bond Yields in the US 1871 - 2016: The Story of a Changing Relationship
2018
Using historical data that spans almost 150 years, we examine whether there is a long-run equilibrium relationship between the stock's earnings and bond yields. The novelty of our econometric methodology consists in using a vector error correction model where we allow multiple structural breaks in the equilibrium relationship. The results of our analysis suggest the existence of equilibrium relationship over 1871-1929 and 1958-2017. On the two historical segments, our analysis finds that the stock's earnings yield followed the bond yield in both the short- and long-run, but not the other way around. Perhaps the most important and surprising finding of our empirical study is that, after the …

Atomic layer deposition of Ti-Nb-O thin films onto electrospun fibers for fibrous and tubular catalyst support structures
2018
Here, the authors report on the preparation of core-shell carbon-ceramic fibrous as well as ceramic tubular catalyst supports utilizing electrospinning and atomic layer deposition (ALD). In this paper, ALD of Ti-Nb-O thin films using TiCl4, Nb(OEt)5, and H2O as precursors is demonstrated. According to the time-of-flight-elastic recoil detection analysis and Rutherford backscattering spectrometry, carbon and hydrogen impurities were relatively low, but depend on the pulsing ratio of the precursors. Optimized ALD process was used for coating of sacrificial electrospun polyvinyl alcohol (PVA) template fibers to yield tubular Ti-Nb-O structures after thermal or solution based PVA removal. Anoth…
Exploring the effect of the cyclometallating ligand in 2-(pyridine-2-yl)benzo[d]thiazole-containing iridium(III) complexes for stable light-emitting …
2018
The preparation and characterization of a series of iridium(III) ionic transition-metal complexes for application in light-emitting electrochemical cells (LECs) are reported. The complexes are of the type [Ir(C^N)2(N^N)][PF6] in which C^N is one of the cyclometallating ligands 2-(3-(tert-butyl)phenyl)pyridine (tppy), 2-phenylbenzo[d]thiazole (pbtz), 1-phenyl-1H-pyrazole (ppz) and 1-phenylisoquninoline (piq), and N^N is 2-(pyridine-2-yl)benzo[d]thiazole (btzpy). The variation in the C^N ligands allows the HOMO energy level to be tuned, leading to HOMO–LUMO gaps in the range 2.76–3.01 eV and values of Eox1/2 of 0.81–1.11 V. In solution, the complexes are orange to deep-red emitters (λmax in t…

We describe the historical framework and the main issues (biographical, scientific, political, etc.) of the correspondences of Placido Tardy and Luigi Cremona in the libraries of Genoa, which constitute an important contribution to the reconstruction of the History of Mathematics in the Italian “Risorgimento”. In particular, we mainly deal with the Cremona-Tardy, Betti-Tardy and Cremona-Guccia correspondences. Tardy’s letters are preserved at the Genoa University Library and Cremona’s letters at the Mazzini Institute of Genoa.
Techniques to Analyze sRNA Protein Cofactor Self-Assembly In Vitro
2018
Post-transcriptional control of gene expression by small regulatory noncoding RNA (sRNA) needs protein accomplices to occur. Past research mainly focused on the RNA chaperone Hfq as cofactor. Nevertheless, recent studies indicated that other proteins might be involved in sRNA-based regulations. As some of these proteins have been shown to self-assemble, we describe in this chapter protocols to analyze the nano-assemblies formed. Precisely, we focus our analysis on Escherichia coli Hfq as a model, but the protocols presented here can be applied to analyze any polymer of proteins. This chapter thus provides a guideline to develop commonly used approaches to detect prokaryotic protein self-ass…
The Effectiveness of Physical Exercise on Bone Density in Osteoporotic Patients
2018
Physical exercise is considered an effective means to stimulate bone osteogenesis in osteoporotic patients. The authors reviewed the current literature to define the most appropriate features of exercise for increasing bone density in osteoporotic patients. Two types emerged: (1) weight-bearing aerobic exercises, i.e., walking, stair climbing, jogging, and Tai Chi. Walking alone did not appear to improve bone mass; however it is able to limit its progressive loss. In fact, in order for the weight-bearing exercises to be effective, they must reach the mechanical intensity useful to determine an important ground reaction force. (2) Strength and resistance exercises: these are carried out with…

Wake and Turbulence Analysis for Wind Turbine Layouts in an Island
2018
There is a big wind energy potential in supplying the power in an island and most of the islands are off-grid. Due to the limited area in island(s), there is need to find appropriate layout / location for wind turbines suited to the local wind conditions. In this paper, we have considered the wind resources data of an island in Trøndelag region of the Northern Norway, situated on the coastal line. The wind resources data of this island have been analysed for wake losses and turbulence on wind turbines for determining appropriate locations of wind turbines in this island. These analyses are very important for understanding the fatigue and mechanical stress on the wind turbines. In this work,…
