On Nonoscillation of Mixed Advanced-Delay Differential Equations with Positive and Negative Coefficients

For a mixed (advanced--delay) differential equation with variable delays and coefficients $$\dot{x}(t) \pm a(t)x(g(t)) \mp b(t)x(h(t)) = 0, t\geq t_0$$ where $$a(t)\geq 0, b(t)\geq 0, g(t)\leq t, h(t)\geq t$$ explicit nonoscillation conditions are obtained.Comment: 17 pages; 2 figures; to appear in Computers & Mathematics with Application

Efficient redistribution policy: an analysis focused on the quality of institutions and public education

In this work we intend to study how the quality of the institutional factor may influence the efficiency of redistribution policy specifically associated with human capital accumulation. We develop a conceptual discussion building on the importance of income redistribution for economic growth and the key role of political institutions in securing growth-enhancing redistribution policies. We introduce endogenous growth theory elements into our analysis by considering as a fundamental source of economic growth human capital accumulation, motivated by tax-financed education secured through efficient redistribution policies. We outline crucial insights on the underlying mechanisms, emphasizing however that extensive research on the subject is undoubtedly still required. In particular, we identify the main factors negatively affecting the decisive role of political institutions and, consequently, distorting efficient redistribution policy. We then define a political-economic equilibrium as a combination of intermediately strong state and efficient control-rights institutions, implying simultaneous protection from expropriation and implementation of efficient redistribution policy, conducive to sustained economic growth.redistribution policy, human capital, institutions, taxation, public education, economic growth

Optical observations of GRB 060218/SN 2006aj and its host galaxy

The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date ($z$=0.033) and is the clearest example of a SN associated with a Swift GRB with the earliest optical spectroscopy. Its optical data showed that this is the fastest evolving and among the least luminous GRB-SNe (70% as luminous as SN1998bw). However, its expansion velocity and a comparison with other stripped-envelope SNe suggest that SN2006aj is an intermediate object between Type Ic GRB-SNe and those not accompained by a GRB. High-resolution optical spectroscopy together with SDSS pre-burst observations revealed that the host galaxy of SN2006aj is a low-luminosity, metal-poor star-forming dwarf galaxy.Comment: To appear in conf. proc. of "The Multicoloured Landscape of Compact Objects and their Explosive Progenitors: Theory vs Observations", a conference held in Cefalu, Sicily, June 11-24, 200

Estereotipos de género en universitarios españoles sobre el riesgo psicosocial en la infancia

Recent studies have shown that gender stereotypes are not sensitive to social changes. There is a gap in how gender is treated in college. This study is part of an innovation project to improve teaching quality in university. We aim to analyze the presence of gender stereotypes related to at-risk childhood in a sample of 113 university students. Most students considered that some circumstances, like substance consumption, are more likely in boys. On the contrary, they think that looking after siblings or anxiety are more common in girls. Results show the need to incorporate the gender perspective into universities. The special needs of the at-risk girls require further research and specialized training.Estudios recientes han mostrado que los estereotipos de género no son sensibles a los cambios sociales. Hay un vacío sobre cómo el género es tratado en la educación universitaria. Este estudio se enmarca en un proyecto de innovación para la mejora de la calidad docente en la universidad. Pretendemos analizar la presencia de estereotipos de género relacionados con menores en riesgo en una muestra de 113 universitarios. La mayoría de los estudiantes considera que algunas circunstancias, como el uso de sustancias, son más probables en chicos. Por el contrario, piensan que el tener que cuidar de los hermanos o la ansiedad son más comunes en chicas. Los resultados muestran la necesidad de incorporar la perspectiva de género en las universidades. Las necesidades de las chicas en riesgo requieren más investigación y formación especializada

Territoriality and urban policy: addressing territorial complexity

In che modo affrontiamo le istanze poste dalla complessità del territorio nelle pratiche e nella definizione di politiche territoriali? Cosa è la territorialità e quali possono le variabli in gioco nei processi di territorializzazione dei fenomeni urbani? Per rispondere a queste domande il contributo introdurrà la nozione di regione, territorio, luogo, territorialità e territorializzazione. In seguito si analizzano le variabili e le dimensioni emerse, nell’abito della sessione Terrioriality and Urban Policies, nell’affrontare le istanze poste dalla complessità territoriale. Tali dimensioni della “produzione territoriale” saranno qui trattate come un punto di partenza per una definizione delle politiche territoriali che sia informata dall’analisi dei fenomeni urbani e il più possibile aderente alla complessità dei territori contemporanei.How do we deal with territorial complexity in present urban territorial policies and practices. What is territoriality and what are the dimension od territorial production ? In order to explore this issue the contribute will unpack in the first paragraph the notion of region, territory, place, territoriality and territorialisation. In the second paragraph it will outline the dimension of territorial production that inform urban and territorial policies as emerged from the conference parallel session on Territoriality and urban policy. These dimension might inform future approach in territorial policy making.Peer Reviewe

A Similarity Measure for Material Appearance

We present a model to measure the similarity in appearance between different materials, which correlates with human similarity judgments. We first create a database of 9,000 rendered images depicting objects with varying materials, shape and illumination. We then gather data on perceived similarity from crowdsourced experiments; our analysis of over 114,840 answers suggests that indeed a shared perception of appearance similarity exists. We feed this data to a deep learning architecture with a novel loss function, which learns a feature space for materials that correlates with such perceived appearance similarity. Our evaluation shows that our model outperforms existing metrics. Last, we demonstrate several applications enabled by our metric, including appearance-based search for material suggestions, database visualization, clustering and summarization, and gamut mapping.Comment: 12 pages, 17 figure
