Analistas simbólicos, jerarquía urbana y atracción de talento en las ciudades mundiales españolas (2005-2019): un análisis a partir de la EPA
2021
Este trabajo utiliza los microdatos de la Encuesta de población activa del INE entre 2005 y 2019 para analizar el nivel de competencias de la población ocupada, los procesos de cualificación del mercado de trabajo de las ciudades mundiales españolas (Madrid, Barcelona, Valencia, Sevilla y Bilbao) y el papel que están teniendo las migraciones de profesionales y técnicos altamente cualificados como reflejo de su capacidad diferencial para atraer talento externo. Siguiendo el marco conceptual propuesto por Allen J. Scott de creciente polarización de los mercados de trabajo metropolitanos entre una clase de «analistas simbólicos» de alta cualificación y una «subclase de servicios», se considera…
Dimensioni di attaccamento e formazione delle visioni del mondo e delle ideologie
2013
The aim of this study was to investigate the role of attachment dimensions in framing worldviews and socio-political attitudes. A study on 178 Italian university students in Palermo was conducted. A causal model is tested where social conformity, toughmindedness, and insecure attachment dimensions were considered antecedents, and right-wing authoritarianism and social dominance orientation were the dependent variables. The structural equation modeling showed a good fit. The model evidenced the mediation role of worldviews in the relation between social conformity, toughmindedness, attachments, and socio-political attitudes. The avoidance attachment predicted world as competitive jungle, the…
Quality, Reliability, Security and Robustness in Heterogeneous Systems
2020
This book constitutes the refereed post-conference proceedings of the 15th EAI International Conference on Quality, Reliability, Security and Robustness in Heterogeneous Networks, QShine 2019, held in Shenzhen, China, in November 2019. The 16 revised full papers were carefully reviewed and selected from 55 submissions. The papers are organized thematically in tracks, starting with mobile systems, cloud resource management and scheduling, machine learning, telecommunication systems, and network management.
Molecular Signatures of Biogeochemical Transformations in Dissolved Organic Matter from Ten World Rivers
2016
Rivers carry large amounts of dissolved organic matter (DOM) to the oceans thereby connecting terrestrial and marine element cycles. Photo-degradation in conjunction with microbial turnover is considered a major pathway by which terrigenous DOM is decomposed. To reveal globally relevant patterns behind this process, we performed photo-degradation experiments and year-long bio-assays on DOM from ten of the largest world rivers that collectively account for more than one-third of the fresh water discharge to the global ocean. We furthermore tested the hypothesis that the terrigenous component in deep-sea DOM may be far higher than biomarker studies suggest, because of the selective photochemi…
BORDERS AND BORDER CROSSING BETWEEN ART WORLDS. Successful attempts and epic failures to enter new domains in recent British art
2016
The paper attempts to answer, whether it is possible for successful artists in one specific sector to access the domain of another artistic field at their free will. In doing so, this contribution analyses the possible existence of borders and gatekeepers between different art worlds. The aim is not just finding or defining boundaries between art fields, but rather understanding, if boundaries can be pierced through, as well as the conditions that might hinder acceptance. Moving from an art theoretical and philosophical perspective, the present paper will discuss the thesis of Pierre Bourdieu, Howard Becker, Berys Gaut and Joseph Margolis on boundary conditions in the arts. Subsequently the…
Scale-dependent plant diversity in Palaearctic grasslands: a comparative overview
2016
Here we present an extensive overview of plant diversity values in Palaearctic grasslands for seven standard grain sizes from 0.0001 to 100 m². The data originate from 20 studies, including the Field Workshops of the Eurasian Dry Grassland Group (EDGG), ranging geographically from Spain in the west to Siberia in the east, from Sicily in the south to Estonia in the north and from the sea coast up to 3100 m a.s.l. The majority of data is from dry grasslands (Festuco-Brometea, Koelerio-Corynephoretea, Cleistogenetea squarrosae), but there are also some mesic, wet, saline, acidic, alpine and Mediterranean grasslands included. Among others, we compiled data from 1795 1-m², 1109 10-m² and 338 100…
Patterns of international capital flows and their implications for developing countries
2017
According to standard economic theory, capital should flow from rich to poor countries. However, a reverse pattern has prevailed in the world economy. This is the so-called Lucas paradox. In addition, it has been shown that, counterintuitively, there is a negative correlation between capital inflow and productivity growth across developing countries. This is the so-called allocation puzzle. This review sheds light on the following questions: “What are the patterns of international capital flows in the world economy?”, “What are the most plausible explanations for these patterns?”, and “What are the possible implications of these developments for developing countries?” In addition, the curre…
Big Data Metadata Management in Smart Grids
2014
Smart home, smart grids, smart museum, smart cities, etc. are making the vision for living in smart environments come true. These smart environments are built based upon the Internet of Things paradigm where many devices and applications are involved. In these environments, data are collected from various sources in diverse formats. The data are then processed by different intelligent systems with the purpose of providing efficient system planning, power delivery, and customer operations. Even though there are known technologies for most of these smart environments, putting them together to make intelligent and context-aware systems is not an easy task. The reason is that there are semantic…
Taking Online Search Queries as an Indicator of the Public Agenda
2016
Recently, several studies suggested that the amount of online search queries can be used as an indicator of the public agenda. Based on former research by the authors, this article discusses the role of public uncertainty as another factor influencing search queries. Therefore, the influence of media coverage on Wikipedia searches concerning two issues is compared: one issue with uncertainty (the Enterohaemorrhagic Escherichia coli [EHEC] epidemic), and one without uncertainty (unemployment). Analyses show much stronger correlations in the case of EHEC, which suggests that online search behavior may especially be used as an indicator of the public agenda in case public uncertainty exists.
Context Comparison for Object Fusion
2003
We propose a solution to help the integration of heterogeneous sources based on the fusion of objects according to their context. New requirements for information exchange have emerged with all the developments around Internet. Information consumers want to access and combine data from remote and heterogeneous sources in a transparent and dynamic way. To achieve this level of interoperation is yet a real challenge. We present a model to define local data as informative objects with a contextual representation associated to them. A semantic context comparison mechanism, based on a semantic distance, reconciles context of applications and constructs virtual objects in which rules make the fus…
