Kolāžu izmantošana vārdu krājuma nostiprināšanai angļu valodas stundās 3. klasē
2015
Diplomdarba mērķis bija atrast veidu, kā nostiprināt vārdu krājumu svešvalodā 3. klasē, pārvēršot to par aktīvu vārdu krājumu, izmantojot kolāžas. Darba tēma tika izvēlēta, jo autore tic, ka vārdu krājums ir pamats svešvalodu apgūšanā. Skolotāja uzdevums ir palīdzēt skolēniem apgūt vārdu krājumu, izmantojot vizuālos materiālus mācību procesā pēc iespējas vairāk. Izvēlētā pētījuma metode bija atsevišķa gadījuma pētījums, kas tika veikts Rīgas 32. vidusskolā 3. klasē. Datu vākšanas metodes bija 2 testi skolēniem, intervija ar vietējo angļu valodas skolotāju un skolēnu anketa. Pētījums pierādīja to, ka skolēni izbaudīja laiku veidojot kolāžas, turklāt skolēni nostiprināja vārdu krājumu angļu v…
Visual working memory resource allocation mechanism in consolidation and maintenance phase
2018
Visual working memory (VWM) is a system for actively maintaining visual information to meet the needs of an ongoing task. It allows individuals to store visual input information from a complex outside environment and provides storage space as an information buffer platform to help integrate information into a continuous visual experience. This research examined the consolidation and maintenance phase of the VWM resource allocation mechanism. Four aspects of this issue were investigated. First, resource allocation in VWM consolidation was investigated for different materials, and it was determined whether VWM resources were allocated in a serial manner for orientation materials but in a limi…
Negative emotional state modulates visual working memory in the late consolidation phase
2020
Although a considerable literature has grown up around the interactions between emotional state and visual working memory (VWM) performance, the mechanism underlying the impact of the negative emotional state on VWM remains unclear. The present study aimed to test whether the influence of emotional state is related to the early phase or late phase of VWM consolidation process. Across three experiments, we found that the negative emotional state did not affect VWM performance when the presentation time of stimuli was short. However, when the presentation time was long, the negative emotional state increased the VWM precision and reduced the VWM number. According to the two-phase model propos…
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…
El alojamiento colaborativo: Viviendas de uso turístico y plataformas virtuales
2016
La llamada economía colaborativa, fenómeno innovador de alcance global y transversal, supone la apuesta por una alternativa a las prácticas hasta ahora conocidas en nuestra sociedad de consumo. Esta idea de la economía colaborativa ha tenido una gran repercusión más allá de su incidencia en los mercados de servicios y bienes, afectando de forma directa al sector del alojamiento turístico. De hecho, se han generalizado de forma extraordinaria diferentes alternativas al alojamiento vacacional más tradicional, mediante plataformas virtuales que ofrecen viviendas privadas para su uso turístico a precios competitivos y prometen experiencias más cercanas a la convivencia vecinal que turística. An…
Liela apjoma datu vizualizācija uz augstas izšķirtspējas displeju sienas
2016
Liela datu apjoma atainošanas problēma vienmēr bijusi aktuāla, un, šim apjomam strauji pieaugot, problēma paliek arvien aktuālāka. Izmantojot ierastās iekārtas (displejus), liela apjoma datu atainošanai, dati tiek attēloti ļoti lielā blīvumā, kas neļauj izšķirt detaļas, savukārt apskatot datus tuvinājumā zūd priekšstats par kopējo ainu. Attīstoties displeju ražošanas tehnoloģijām, tiek ražoti displeji ar arvien lielāku izšķirtspēju, bet datu apjomi ir apsteiguši šo displeju iespējas. Mūsdienu tehnoloģiju attīstība ir ļāvusi radīt tādus produktus kā “Displeju siena”, kas neierobežo parādāmā rastra attēla izšķirtspēju ar vienas iekārtas…
Maltrato y enfermedad mental. Estudio de personas con enfermedad mental, víctimas de maltrato
2011
Se realiza un trabajo de investigación sobre la victimización de personas con enfermedad mental, desde la perspectiva de que este colectivo es con frecuencia víctima de maltrato, a pesar de los prejuicios y el estigma que pende sobre él. Dada su especial vulnerabilidad social, los y las profesionales que atienden a esta población tienen la responsabilidad de visibilizar este fenómeno, y validar los instrumentos de diagnóstico que utilizan como útiles para detectar maltrato. The thesis involved research on the victimization of people with mental illness from the angle of this group often being the victim of abuse, despite the prejudice and stigma that hangs over it. Given its special social …
Consolidation tests on the graffiti of the Steri’s prison with nanotechnological Ca(OH)2 dispersed in iso-propanol
2009
The combination of weathering and human activities often induce pyhisicochemical alteration on the surface of wall paintings. One of the most still largely used restoration techniques for these works of art, is based on the application of organic polymers. Due to their ability to stick detached and powdered pigments,these products provide an immediate consolidating effects. Unfortunately, both their aging and their pyhisicochemical incompatibility with the inorganic support can have serious consequences also causing further damage to the work of art. In this paper a new technological approach is presented based on the use of Ca(OH)2 nanoparticles dispersed in isopropanol. Some applicative t…

Electrochemical treatment of real wastewater with low or high conductivity
2018
In the last years, many efforts have been devoted to the development of electrochemical processes for the effective treatment of wastewater contaminated by organic pollutants resistant to conventional biological processes and/or toxic for microorganisms [1–5]. It was shown that some electrochemical approaches, including the direct anodic oxidation at suitable anodes such as boron-doped diamond (BDD) and/or electro-Fenton (EF) at suitable operating conditions and cells [1–6] can allow to treat effectively a very large number of organic pollutants. However, most of the investigations were performed using synthetic wastewater. Hence, it is now mandatory to study the problems connected to the p…
