Regular functions on spherical nilpotent orbits in complex symmetric pairs: Exceptional cases

Given an exceptional simple complex algebraic group G and a symmetric pair (G, K), we study the spherical nilpotent K-orbit closures in the isotropy representation of K. We show that they are all normal except in one case in type G(2), and we compute the K-module structure of the ring of regular functions on their normalizations

瑞吉欧·艾米利亚的教师研究： 一个充满活力并不断演变的角色的精髓 / Teacher Research in Reggio Emilia: Essence of a Dynamic, Evolving Role (Chinese translated version).

The Reggio Emilia approach to early childhood education has been studied for more than 50 years. Today, following the influx of new families, tighter financial situation in local government and a generational turnover of educators, there are changes seen in the role and practice of teachers, but also continuities with the past. Teachers are seen as researchers, where research is not only an attitude and approach in everyday living in and outside early childhood programs, but also a questioning attitude and inquiry process. Besides, as colleagues within a network and organization, teachers, with mutual collaboration, and observing and documenting child’s behaviors together, share experience on promoting child learning. For this purpose they establish a “diffuse pedagogical system” to make interactions and innovations, and to exchange knowledge and experience among schools. Furthermore, as curriculum designers and executors, teachers help children find meaning in what they do, what they encounter, and what they experience by applying “flexible planning” project approach and “pedagogy of listening” to listen inner voices of children. Moreover, as creators of the environment, teachers strongly believe that environment as a third teacher can guide children to pay attention to nature, animals and plants, and emotional and physical nourishment of human beings. Additionally, as guiders in fostering exchange and community, teachers endeavor to make educational institution more inclusive of all children. Last but not least, as partners with families, teachers focus more on parent participation, support and collaboration, such as hiring cultural mediators to instruct the participation of special children families (e.g. immigrant families) 意大利瑞吉欧·艾米利亚幼儿教育体系已经历30 余年的研究历程。近年来， 随着移民家庭的不断涌入、当地政府财务状况的不断紧缩、教育工作者的世代更替等，关于 教师角色定位及其教育实践都发生了许多新的变化。今天，作为儿童研究者，研究是教师 在园内园外的一种日常生活及工作方式，一种质疑和探究的态度和过程；作为工作网络和 组织机构中的同僚，教师需要通过团队合作，共同观察、记录儿童的表现，分享有关促进儿 童发展的经验，为此，他们还建立了一种“拓展性教学体系”，让许多学校开展互动，创新和 交换知识经验；作为课程设计和实施者，教师坚持“灵活计划”的方案教学，并运用“倾听教 学法”，倾听儿童的声音，引导儿童发现他们各种经历和体验的意义；作为环境创造者，教师 更强调让环境成为第三老师，以引导儿童关注自然以及动植物和人自身的生理、情绪等；作 为促进交流和形成社区归属感的指导者，教师须努力促使教育机构对全体幼儿更具包容 性；作为家庭的合作伙伴，教师更关注家长的参与、支持和合作，例如，通过雇佣文化调解员 为特别儿童家庭（如移民家庭）的“参与”提供指导

Robust Control Architecture for Waste Heat Harvesting with Non-Inverting Buck-Boost Converter

Thermoelectric generators (TEG) can be used to harvest wasted heat. TEGs are characterized by a wide output voltage range and a considerable output resistance leading to a maximum power point dependent on the working temperature. Non-Inverting Buck-Boost converter is used to manage, from one side, the wide voltage range, and from the other a battery. This article investigates a robust control architecture to recover the maximum energy from the exhaust's heat avoiding instability issues and maximizing converter efficiency

Still ‘fire in the (full) belly’? Anti-establishment rhetoric before and after government participation

Scholars argued that anti-establishment parties use a populist rhetoric that appeals to the worst instincts of people. Indeed, populist politicians are often viewed as charismatic leaders that have fire in their belly. While in the past these parties heavily relied on anti-establishment platforms and communication rhetoric, their increasing electoral success along with the growing duties linked with government membership transform them into more established parties, rather than pure outsiders, and cast doubts on the feasibility of keeping a populist rhetoric. This paper compares right-wing and non-right-wing populism, investigating whether populist leaders change their rhetorical strategy once in office, decreasing the level of negativity and adopting a more forward-looking and inclusive style of communication, with a stronger focus on fulfilling the policy proposal made during the electoral campaign rather than blaming political rivals. For this purpose, we collected a new corpus of political speeches extracted from video messages posted on Facebook by four anti-establishment party leaders in three countries (Austria, Italy and Spain), from 2016 to 2018, i.e., immediately before and immediately after their access to power. Overall, 30 h of recorded audio from 215 videos (amounting to around 140 million visualizations) have been analyzed using topic models and well-established semantic psycholinguistic dictionaries. The results highlight slight changes in the rhetoric of populist leaders once in power, mostly for non-right-wing populists, as their language becomes less negative, less assertive and more focused on government duties

Improving Knowledge of Risk in Dangerous Goods Transport

In order to increase safety as far as dangerous goods transport is concerned, the DESTINATION project has been developed since 2010 in the framework of the Italy/Switzerland Operational Program for Transfrontier Co-operation 2007-2013. The project was born to satisfy the increasing needs of public bodies to share data on hazardous material land transportation and to develop instruments and methodologies to ensure territorial and environmental protection. The project aims to reach this purpose through the increased knowledge of the vulnerable subjects, people and environment, and of the transport activity itself, by using and defining an architecture of data acquisition based on “On Ground Units” (OGU) and “On Board Units” (OBU). These data will be used as an input for a new information system called GIIS (Global Integrated Information System), which manages a risk analysis model of the land transportation of hazardous materials to assess human and environmental vulnerabilities. The GIIS will provide a more effective management of land planning by providing authorities with the possibility of implementing a rational restriction to vehicles transporting dangerous goods within specific areas

Tendencias y respuestas de la fenología de la superficie terrestre a la variabilidad climática en la Pampa Argentina

Comprender la interacción entre los procesos de la superficie terrestre y la atmósfera es fundamental para predecir los efectos del cambio climático futuro sobre el funcionamiento de los ecosistemas y la dinámica del carbono. Los objetivos de este trabajo fueron analizar las tendencias en métricas de la fenología de la superficie terrestre derivadas de sensores remotos, y revelar su relación con la precipitación y el fenómeno ENSO en la región pampeana de Argentina. A partir de una serie temporal de imágenes del Índice de Vegetación de Diferencia Normalizada (NDVI) de MODIS para el período 2000-2014, se obtuvo para la región pampeana de Argentina el inicio de la estación de crecimiento (SOS), la integral anual del NDVI (i-NDVI, estimador lineal de la productividad anual), el tiempo del máximo anual del NDVI (t-MAX) y el rango relativo anual de NDVI (RREL, estimador de la estacionalidad). Posteriormente, se analizaron las relaciones espaciales y temporales con el Índice Multivariado del ENSO (MEI) y la precipitación. Los resultados mostraron una tendencia negativa en la productividad anual en un 53,6% del área de estudio asociado a zonas de pastizales naturales y semi-naturales, mientras que un 40,3% de la Pampa Argentina mostró una tendencia positiva significativa en la estacionalidad de las ganancias de carbono. Este estudio también revela que la variabilidad climática tiene un impacto significativo en la fenología de la superficie terrestre de la región pampeana, aunque este impacto es heterogéneo. SOS y t-MAX mostraron una correlación negativa significativa con la precipitación, lo que indica una ocurrencia más temprana. El 23,6% y 28,4% del área de estudio mostró una correlación positiva de la productividad anual con el MEI y la precipitación, respectivamente, asociado a pastizales (en el primer caso) y sobre pastizales y áreas agrícolas en el segundo caso. La variabilidad climática no explicó la variabilidad en la estacionalidad de la fenología. Las relaciones encontradas entre las métricas de la fenología de la superficie terrestre y la variabilidad climática podrían ser importantes para la implementación de estrategias para el manejo de los recursos naturales.Understanding the interaction between land surface and atmosphere processes is fundamental for predicting the effects of future climate change on ecosystem functioning and carbon dynamics. The objectives of this work were to analyze the trends in land surface phenology (LSP) metrics from remote sensing data, and to reveal their relationship with precipitation and ENSO phenomenon in the Argentina Pampas. Using a time series of MODIS Normalized Difference Vegetation Index (NDVI) data from 2000 to 2014, the start of the growing season (SOS), the annual integral of NDVI (i-NDVI, linear estimator of annual productivity), the timing of the annual maximum NDVI (t-MAX) and the annual relative range of NDVI (RREL, estimator of seasonality) were obtained for the Argentina Pampas. Then, spatial and temporal relationships with the Multivariate ENSO Index (MEI) and precipitation were analyzed. Results showed a negative trend in annual productivity over a 53.6% of the study area associated to natural and semi-natural grassland under cattle grazing, whereas a 40.3% of Argentina Pampas showed a significant positive trend in seasonality of carbon gains. The study also reveals that climate variability has a significant impact on land surface phenology in Argentina Pampas, although the impact is heterogeneous. SOS and t-MAX showed a significant negative correlation with the precipitation indicating an earlier occurrence. 23.6% and 28.4% of the study area showed a positive correlation of the annual productivity with MEI and precipitation, respectively, associated to rangelands (in the first case) and to both rangeland and croplands, in the second case. Climate variability did not explain the seasonal variability of phenology. The relationships found between LSP metrics and climate variability could be important for implementation of strategies for natural resource management.Fil: Lara, Bruno Daniel.

Spherical orbit closures in simple projective spaces and their normalizations

Let G be a simply connected semisimple algebraic group over an algebraically closed field k of characteristic 0 and let V be a rational simple G-module of finite dimension. If G/H \subset P(V) is a spherical orbit and if X is its closure, then we describe the orbits of X and those of its normalization. If moreover the wonderful completion of G/H is strict, then we give necessary and sufficient combinatorial conditions so that the normalization morphism is a homeomorphism. Such conditions are trivially fulfilled if G is simply laced or if H is a symmetric subgroup.Comment: 24 pages, LaTeX. v4: Final version, to appear in Transformation Groups.
