Geometric Brownian Motion (GBM) of Stock Indexes and Financial Market Uncertainty in the Context of Non-Crisis and Financial Crisis Scenarios
2022
The present article proposes a methodology for modeling the evolution of stock market indexes for 2020 using geometric Brownian motion (GBM), but in which drift and diffusion are determined considering two states of economic conjunctures (states of the economy), i.e., non-crisis and financial crisis. Based on this approach, we have found that the GBM proved to be a suitable model for making forecasts of stock market index values, as it describes quite well their future evolution. However, the model proposed by us, modified geometric Brownian motion (mGBM), brings some contributions that better describe the future evolution of stock indexes. Evidence in this regard was provided by analyzing …
G-CLASS: geosynchronous radar for water cycle science – orbit selection and system design
2019
The mission geosynchronous – continental land atmosphere sensing system (G-CLASS) is designed to study thediurnal water cycle, using geosynchronous radar. Although the water cycle is vital to human society, processes on timescalesless than a day are very poorly observed from space. G-CLASS, using C-band geosynchronous radar, could transform this. Itsscience objectives address intense storms and high resolution weather prediction, and significant diurnal processes such assnow melt and soil moisture change, with societal impacts including agriculture, water resource management, flooding, andlandslides. Secondary objectives relate to ground motion observations for earthquake, volcano, and subs…
Segmentation boundaries in accelerometer data of arm motion induced by music : online computation and perceptual assessment
2022
Segmentation is a cognitive process involved in the understanding of information perceived through the senses. Likewise, the automatic segmentation of data captured by sensors may be used for the identification of patterns. This study is concerned with the segmentation of dancing motion captured by accelerometry and its possible applications, such as pattern learning and recognition, or gestural control of devices. To that effect, an automatic segmentation system was formulated and tested. Two participants were asked to ‘dance with one arm’ while their motion was measured by an accelerometer. The performances were recorded on video, and manually segmented by six annotators later. The annota…
Izvērtējošā leksika produktu aprakstos
2016
Izvērtējošā leksika, arī pasīzstama kā novērtēšana, ir specifiska pieeja, kas izmantota, lai izpētītu, aprakstītu un izskaidrotu kā valoda ir lietota, lai paustu kāda izvērtējumu attiecībā uz konkrētu fenomenu vai uzvedību, kā arī ieņemtu konkrētu nostāju attiecībā uz tekstā izteikto priekšlikumu. Novērtēšana ir viens no trim galvenajiem diskursa semantiskajiem resursiem, kas veido interpersonālu nozīmi, kopā ar ‘līdzdalību’ un ‘vienošanos’. Šī pētījuma mērķis ir izpētīt, kā dažāda izvērtējošā leksika izmantota produktu aprakstos, un kā pareizs izvērtējošās leksikas lietojums var tikt izmantots kā stratēģija, lai palielinātu tirdzniecību. Metodoloģija izmantota šajā pētījumā ir korpusa ling…
International Student Migration in Finland
2021
There is increasing attention on the retention of international students with many stakeholders desiring to keep international students for long-term economic growth. This study examines the factors affecting international students to stay in Finland five years after initial enrolment with particular focus on the role graduation plays in students staying or leaving. Tracking 11 (years) entering cohorts for five years across national (Finland) data registries, we found evidence of an inverse relationship between graduation, degree type, and the probability of staying; higher the degree level of graduation, the decrease in probability an international student stays. We conclude that while gra…
Considerations about an indicator aimed at describing the energy efficiency of buildings with innovative envelope components at different climatic co…
2020
Green roofs are building components that have become increasingly common in urban contexts because other than the general improvement of the aesthetics of the buildings equipped with them, they have demonstrated to positively improve the building energy performance. Consequently, it would be useful for technicians to have easy and reliable indicators to achieve a synthetic quantitative judgement about the effectiveness of green roofs by an energy perspective compared to others building envelope technologies, for different climates. In sight of the definition of such an indicator, or at least of its properties, some considerations aimed at this purpose, especially concerning the use of new c…
Groove Experience: Emotional and Physiological Responses to Groove-Based Music
2009
Theories of music and emotion suggest that subjective affective experience and physiological arousal are elicited by anticipation of musical-structural events. However, little is known about to what extent groove-based music elicits such expectancies, and consequently how it is experienced. Due to the repetitiveness of the groove, it was hypothesised that microtiming in groove might facilitate a type of arousal that is not peak-based, but rather reflects the groove state of listening, which has been conceptualized as a steady mental state in synchronization with the music. An initial qualitative interview study with three groove-based music producers and musicians investigated the subjectiv…
Blended transdiagnostic group CBT for emotional disorders: A feasibility trial protocol
2021
Introduction Emotional disorders (anxiety and depressive disorders) are a relevant public health concern associated with high prevalence, high costs, and important disability. Therefore, research priorities include designing and testing cost-effective interventions to reach everyone in need. Internet-delivered interventions for emotional disorders are effective and can help to disseminate and implement evidence-based treatments. However, although these treatments are generally effective, not all patients benefit from this treatment format equally. Blended treatments are a new form of intervention that combines the strengths of face-to-face and Internet approaches. Nevertheless, research on …

Challenges Associated with Reading Acquisition in Sub-Saharan Africa : Promotion of Literacy in Multilingual Contexts
2019
Heikki Lyytinen and his co-authors note the problems of poorly trained teachers and large class sizes in Africa. Drawing on experience in Zambia, they present a case study of a digital game that can help overcome these problems and lead to more effective literacy instruction, particularly for students facing barriers to learning how to read. peerReviewed
