Economic Activity in Context of Regions, Education Level, Age Group and Gender: Case of Latvia
2019
In the National Development Plan of Latvia 2014–2020 it is written that society is aware that social, regional and opportunity inequalities can be reduced by a high overall employment rate in which everyone seeks for productivity. High employment rate is important not only for decreasing inequalities in country, but also for promoting economic growth. There have always been employment challenges in Latvia that are complex and insufficiently researched in academic research. The aim of the study is to analyse economic activity in Latvia by regions, education level, age group and gender. Research methods used in preparation of the article: scientific publication and previous conducted research…
The impact of regional demographics on Higher Education Policy. An example from Silesia, Poland
2021
Abstract The determinants of higher education policy have their sources in various spheres, such as economic, social, educational, national policy, administrative, and demographic. Problems for the development of higher education also stem from these spheres. One of them is the challenging demographic situation that is a significant element of developing higher education in southern Poland (particuarly in the Silesia region). Given this context, this article aims to indicate the policies of the universities in the region which respond to the existing demographic threats. This relationship is to confront student opinions regarding their vision for their education and future career within the…
Alteration-Induced Volcano Instability at La Soufrière de Guadeloupe (Eastern Caribbean)
2021
International audience; Volcanoes are unstable structures that deform laterally and frequently experience mass wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes significantly to volcano instability. We present a study that combines laboratory experiments, geophysical data, and large-scale numerical modeling to better understand the influence of alteration on volcano stability, using La Soufrière de Guadeloupe (Eastern Caribbean) as a case study. Laboratory experiments on variably altered (advanced argillic alteration) blocks show that uniaxial compressive strength, Young's modulus, and cohesion decrease as a function of increasing alteration, but that …
Use of trans-labial ultrasound in the diagnosis of female urethral diverticula: A diagnostic option to be strongly considered.
2015
AIM: To demonstrate effectiveness of trans-labial ultrasound (TL-US) in the evaluation of female urethral diverticula (UD). METHODS: In the study period, 20 UD were diagnosed and treated. All data on demographic characteristics, presenting symptoms, physical examination findings, diagnostic and operative procedures, were considered. Patients were referred to TL-US for diverticular evaluation, using a 2D 7.5-MHz endfire probe. For each UD, size, complexity, echogenicity content, and presence of diverticular neck were considered. Follow-up controls were carried out at 1, 6 and 12 months after surgery, to evaluate outcome and need for further intervention. RESULTS: Mean patient age was 46 year…
Infographics as a Reflective Assignment Method in Requirements Engineering e-Course?
2019
Our Work in Progress Paper in Innovative Practice Category focuses on how learners’ experience use of infographics in advanced level e-course on requirements engineering (RE). Infographics are visual representations of information in such a way that information can be easily understood at a glance. Most of the previous infographics studies have been conducted in the context of inquiry learning. To complement this research, we studied how learners experience use of infographics as a method for reflective assignment and hence if the usage of infographics supported conceptualization about RE. We adopted a qualitative content analysis approach, applying thematic network analysis to the data rec…
Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication
2016
The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with com…
Discipline del Design e “Slow Journalism”: un antidoto alle fake-news
2021
L’articolo sviluppa una riflessione a partire da un’esperienza di ricerca maturata all’interno dell’Università degli Studi di Palermo nell’ambito del progetto PO FERS “Fake News” che aveva come obiettivo quello di elaborare nuovi e più efficaci meccanismi automatici di valutazione dell’autenticità, originalità e rilevanza dell’informazione prodotta dal giornalismo etico e partecipativo a partire da metodologie e strumenti progettuali propri del design della comunicazione e dell’informazione. The article develops a reflection on a research experience gained within the University of Palermo in the context of the PO FERS “Fake News” project, which aimed to develop new and more effective automa…
Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates
2021
We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops. A survey of the perception of the farmers, and an assessment of the biophysical impact of catch crops (CC) and tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (single ring infiltrometer), and runoff generation and soil erosion (rainfall simulation experiments) was carried out. Two representative fields as study sites were selected in Les Alcusses valley, within Els Alforins…
A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission Measurements
2017
Recently, we reported on the development of low-cost ultraviolet (UV) cameras, based on the modification of sensors designed for the smartphone market. These units are built around modified Raspberry Pi cameras (PiCams; ≈USD 25), and usable system sensitivity was demonstrated in the UVA and UVB spectral regions, of relevance to a number of application areas. Here, we report on the first deployment of PiCam devices in one such field: UV remote sensing of sulphur dioxide emissions from volcanoes; such data provide important insights into magmatic processes and are applied in hazard assessments. In particular, we report on field trials on Mt. Etna, where the utility of these devices in quantif…
A model of degassing for Stromboli volcano
2010
International audience; A better understanding of degassing processes at open-vent basaltic volcanoes requires collection of new datasets of H2O–CO2–SO2 volcanic gas plume compositions, which acquisition has long been hampered by technical limitations. Here, we use the MultiGAS technique to provide the best-documented record of gas plume discharges from Stromboli volcano to date. We show that Stromboli's gases are dominated by H2O (48–98 mol%; mean, 80%), and by CO2 (2–50 mol%; mean, 17%) and SO2 (0.2–14 mol%; mean, 3%). The significant temporal variability in our dataset reflects the dynamic nature of degassing process during Strombolian activity; which we explore by interpreting our gas m…
