Pirms lasīšanas uzdevumi mācību grāmatu tekstiem vārdu krājuma paplašināšanai angļu valodas stundās tehnikumā
2019
Šis diplomdarbs pēta pirms lasīšanas uzdevumu ietekmi uz vārdu krājuma paplašināšanu un lasīšanas izpratni. Tā mērķis ir izstrādāt pirms lasīšanas papildu uzdevumus un izpētīt, kā tie veicina skolēnu sasniegumus vārdu krājuma uzlabošanā. Teorētiskā daļa ir vērsta uz teorijām par ciešu savstarpējo saistību starp lasīšanu un vārdu krājuma pārzināšanu. Empīriskā daļa apraksta gadījumu izpētes rezultātus. Datu vākšanas rīki parādīja priekšrocības, ko sniedz papildu pirms lasīšanas pasākumi studentu grupām, kas bija iesaistītas eksperimentā, salīdzinot ar studentiem, kuri izmantoja tikai mācību grāmatu materiālus. Tiek secināts, ka pirms lasīšanas uzdevumi ir paplašinājuši studentu vārdu krājumu…
Communicating voice emphasis in harpsichord performance
2009
We investigated the means used by harpsichordists to communicate voice-specific melodic emphasis. Twelve harpsichordists were asked to perform a short Baroque polyphonic piece by Frescobaldi (1583-1643) on a harpsichord equipped with a MIDI console. Three conditions were tested, each requiring performers to emphasize a particular voice in the piece (soprano, alto, tenor). Four parameters were analyzed: velocity, note onset asynchrony, timing deviations, and articulation. Mean onset asynchronies were much larger than those observed in organ or piano performance, averaging more than 100 ms between outer voices. However, asynchronies did not vary significantly between conditions, suggesting th…
Sulfur Degassing From Steam-Heated Crater Lakes: El Chichón (Chiapas, Mexico) and Víti (Iceland)
2018
The composition of the gases released by El Chichón (Chiapas, Mexico) and Víti (Askja volcano, Iceland) volcanic lakes is examined by Multi-GAS for the first time. Our results demonstrate that H2S and SO2 are degassed by these pH 2–3 lakes. We find higher CO2/H2S and H2/H2S ratios in the lakes' emissions (31–5,685 and 0.6–35, respectively) than in the fumarolic gases feeding the lakes (13–33 and 0.08–0.5, respectively), evidencing that only a fraction (0.2–5.4% at El Chichón) of the H2S(g) contributed by the subaquatic fumaroles ultimately reaches the atmosphere. At El Chichón, we estimate a H2S output from the crater lake of 0.02–0.06 t/day. Curiously, SO2 is also detected at trace levels …
Lidar detection of carbon dioxide in volcanic plumes
2015
Volcanic gases give information on magmatic processes. In particular, anomalous releases of carbon dioxide precede volcanic eruptions. Up to now, this gas has been measured in volcanic plumes with conventional measurements that imply the severe risks of local sampling and can last many hours. For these reasons and for the great advantages of laser sensing, the thorough development of volcanic lidar has been undertaken at the Diagnostics and Metrology Laboratory (UTAPRAD-DIM) of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). In fact, lidar profiling allows one to scan remotely volcanic plumes in a fast and continuous way, and with high s…
Volcanic Plume CO2 Flux Measurements at Mount Etna by Mobile Differential Absorption Lidar
2017
Volcanic eruptions are often preceded by precursory increases in the volcanic carbon dioxide (CO2) flux. Unfortunately, the traditional techniques used to measure volcanic CO2 require near-vent, in situ plume measurements that are potentially hazardous for operators and expose instruments to extreme conditions. To overcome these limitations, the project BRIDGE (BRIDging the gap between Gas Emissions and geophysical observations at active volcanoes) received funding from the European Research Council, with the objective to develop a new generation of volcanic gas sensing instruments, including a novel DIAL-Lidar (Differential Absorption Light Detection and Ranging) for remote (e.g., distal) …

The marketplace vulnerability of low-income unbanked consumers : a developing country perspective
2018
Financial exclusion is recognised as an important element of socio-economic inequality where economically vulnerable groups are excluded from basic financial services. The issue of financial exclusion is mainly concentrated in the world’s developing countries. However, research on the issue of financial exclusion in the field of marketing as well as from the perspective of unbanked consumers is lacking. Although financial exclusion impedes low-income consumers’ welfare, there is a shortage of wellbeing related studies on low-income consumers in the context of developing countries. This doctoral dissertation aims to investigate the ways in which low-income unbanked consumers experience vulne…
From places to platforms : Examining the transformation of servicescapes
2022
Place represents one of the underlying elements of the marketing mix. However, due to ongoing digitalisation, places have undergone substantial changes in recent years. With the transition from physical shopping environments towards intangible Internet spaces and digital platforms, how places affect consumer behaviour and how consumers use places are rapidly changing. This transition challenges the existing conceptualisation of place as a physical environment. In the online environment, consumers can no longer rely on physical and tangible cues to complement their shopping experience. Instead, they have to learn the logic of technological platforms and the rules of interaction in digital sp…
