Mapping soil water content under sparse vegetation and changeable sky conditions: comparison of two thermal inertia approaches

2013

A critical analysis of a thermal inertia approach to map surface soil water content on bare and sparsely vegetated soils by means of remotely sensed data is reported. The study area is an experimental field located in Barrax, Spain. In situ data were acquired within the Barrax 2011 research project. An advanced hyperspectral scanner airborne imager provides images in the visible/near-infrared and thermal infrared bands. Images were acquired both in day and night times by the Instituto Nacional de Técnica Aeroespacial between 12th and 13th of June 2011. The scene covers a corn irrigation pivot surrounded by bare soil, where a set of in situ data have been collected both previously and simult…

Integreating geological and seismological data in point process models for seismical analysis

2017

Nowadays in the seismic and geological fields, large and complex data sets are available. This information is a valuable source that can be used for improving the seismic hazard assessment of a given region. In particular, the integration of geologic variables into point process models to study seismic pattern is an open research field that has not been fully explored. In this work, we present several open-access datasets (the catalogue of the earthquakes, geological information such as faults, plate boundary and the presence of volcanoes) that are properly treated to describe the seismicity of events occurred in Greece between 2005 and 2014. We use these datasets to fit an advanced spatial…

Models and methods for space and space-time interactions in complex point processes with applications on earthquakes

Collaborative Design Rational and Social Creativity in Cultures of Participation

2011

The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…

Joint second-order parameter estimation for spatio-temporal log-Gaussian Cox processes

2018

We propose a new fitting method to estimate the set of second-order parameters for the class of homogeneous spatio-temporal log-Gaussian Cox point processes. With simulations, we show that the proposed minimum contrast procedure, based on the spatio-temporal pair correlation function, provides reliable estimates and we compare the results with the current available methods. Moreover, the proposed method can be used in the case of both separable and non-separable parametric specifications of the correlation function of the underlying Gaussian Random Field. We describe earthquake sequences comparing several Cox model specifications.

La inscripción de la ciudadanía en la cuba neocolonial (1902-1919) : Sucinta referencia histórico-jurídica

2021

This historical-legal account brieflycovering 17 years of civil registration activity carried out during the neocolonial period by Municipal Judges and Secretaries, specifically that related to registration of Cuban citizens)becomes considerably relevant to understand and to godeeper into the origins of this complex process, as well asto achieve a re-encounter with the history of those who passed through those times, currently a hidden history in the shadows of Civil Registration offices, but still alive and thus allowing us to find all the beauty that there was in it.

Synthesis and Structure Elucidation of Novel Spirooxindole Linked to Ferrocene and Triazole Systems via [3 + 2] Cycloaddition Reaction

2022

In the present work, a novel heterocyclic hybrid of a spirooxindole system was synthesized via the attachment of ferrocene and triazole motifs into an azomethine ylide by [3 + 2] cycloaddition reaction protocol. The X-ray structure of the heterocyclic hybrid (1″R,2″S,3R)-2″-(1-(3-chloro-4-fluorophenyl)-5-methyl-1H-1,2,3-triazole-4-carbonyl)-5-methyl-1″-(ferrocin-2-yl)-1″,2″,5″,6″,7″,7a″-hexahydrospiro[indoline-3,3″-pyrrolizin]-2-one revealed very well the expected structure, by using different analytical tools (FTIR and NMR spectroscopy). It crystallized in the triclinic-crystal system and the P-1-space group. The unit cell p…

Long-term socio-economic impact of COVID-19 on sport sector

2021

The nature of the Covid-19 pandemic’s induced economic crisis is unprecedented: beyond the repeated health and economic shocks, the long-term effects on human capital, productivity and behaviour may also be long-lasting. One of the sectors hit particularly severe by the impacts of Covid-19 is sport. The very existence and work of sport organisations, clubs, professional sport leagues, fitness centres, athletes, coaches, sport staff, sport volunteers and sport-related business, including sport event organisers and sport media, have been battling with staying afloat by cutting all unnecessary expenses and consolidating costs while also trying to maintain the community feel of bringing people …

Impact of the Covid-19 pandemic on sports journalism in Latvia

2022

Bakalaura darba “Covid-19 pandēmijas ietekme uz sporta žurnālistiku Latvijā” mērķis ir noskaidrot, kādas ir galvenās iezīmes, kuras ir mainījušās sporta žurnālistu ikdienā, salīdzinot ar pirms pandēmijas ēru. Tāpat arī veikt intervijas, lai noskaidrotu vadošo sporta žurnālistu paustos naratīvus un atziņas par jauno sporta žurnālisma konceptu. Visbeidzot, ar kontentanalīzes metodi veikt sporta mediju publikāciju analīzi, lai konstatētu kā ir mainījies publicētais saturs. Darba teorētiskajā daļā ir skaidroti žurnālistikas, sporta žurnālistikas procesi un galvenās Covid-19 izmaiņu iezīmes sporta žurnālistikā. Metodoloģiskajā daļā aplūkotas kvantitatīvās kontentanalīzes, daļēji strukturētās int…
