Ceļvedis pilsētu tekstu izpētē

2020

Populārzinātniskā izdevuma pamatā ir trīs daļas: metodoloģiskā, teorētiskā un praktiskā daļa. Pirmā daļa ir paredzēta valodniekiem, valodas pedagogiem un tiem, kuri vēlas iepazīties ar lingvistiskās ainavas teoriju un jaunākajām pedagoģijas teorijām Otrā un trešā daļa ir saistoša valodas apguvējiem un tiem, kurus interesē pilsētu tekstu daudzpusīga izpēte. 1. Metodoloģiskajā daļā tiek runāts par valodas mācīšanas pieejām un refleksīvo pedagoģiju, zināšanu veidošanās procesiem un tekstpratību. 2. Teorētisko daļu veido divas nodaļas, kurās populārzinātniski ir izklāstīti ar pilsētu tekstiem saistīti jautājumi, definēti galvenie termini (t. sk. svešvalodās) un sniegti ieteikumi praktisko pētīj…

A general framework for group authentication and key exchange protocols

2014

Published version of a chapter in the book: Foundations and Practice of Security. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-05302-8_3 In this paper, we propose a novel framework for group authentication and key exchange protocols. There are three main advantages of our framework. First, it is a general one, where different cryptographic primitives can be used for different applications. Second, it works in a one-to-multiple mode, where a party can authenticate several parties mutually. Last, it can provide several security features, such as protection against passive adversaries and impersonate attacks, implicit key authentication, forward and backward securi…

AI ethics:an empirical study on the views of practitioners and lawmakers

2023

Artificial intelligence (AI) solutions and technologies are being increasingly adopted in smart systems contexts; however, such technologies are concerned with ethical uncertainties. Various guidelines, principles, and regulatory frameworks are designed to ensure that AI technologies adhere to ethical well-being. However, the implications of AI ethics principles and guidelines are still being debated. To further explore the significance of AI ethics principles and relevant challenges, we conducted a survey of 99 randomly selected representative AI practitioners and lawmakers (e.g., AI engineers and lawyers) from 20 countries across five continents. To the best of our knowledge, this is the …

Barriers and wellbeing-oriented enablers of intergenerational innovation in the digital age

2021

AbstractSo far, researchers have used a wellbeing-centered approach to catalyze successful intergenerational collaboration (IGC) in innovative activities. However, due to the subject’s multidisciplinary nature, there is still a dearth of comprehensive research devoted to constructing the IGC system. Thus, the purpose of this study is to fill a research void by providing a conceptual framework for information technology (IT) system designers to use as a jumping-off point for designing an IGC system with a wellbeing-oriented design. A systematic literature study was conducted to identify relevant terms and develop a conceptual framework based on a review of 75 selected scientific papers. The …

The impact of remote work and mediated communication frequency on isolation and psychological distress

2022

A massive shift towards remote work practices has presented many organizations and employees with acute challenges associated with multi-locational work. This shift underscores the need to reconsider isolation as one of the focal challenges of organizations in an era of increasingly dispersed and mediated work practices. This study relies on a three-wave survey among Finnish workers to investigate how remote work practices and the use of information and communication technology (ICT) have impacted perceptions of isolation during the global health pandemic, and whether these relationships have an effect on psychological distress. The findings indicate that facilitating the use of ICTs may he…

Automatic social distance estimation for photographic studies: Performance evaluation, test benchmark, and algorithm

2022

The social distancing regulations introduced to slow down the spread of COVID-19 virus directly affect a basic form of non-verbal communication, and there may be longer term impacts on human behavior and culture that remain to be analyzed in proxemics studies. To obtain quantitative results for such studies, large media and/or personal photo collections must be analyzed. Several social distance monitoring methods have been proposed for safety purposes, but they are not directly applicable to general photo collections with large variations in the imaging setup. In such studies, the interest shifts from safety to analyzing subtle differences in social distances. Currently, there is no suitabl…

Modeling and Mitigating Errors in Belief Propagation for Distributed Detection

2021

We study the behavior of the belief-propagation (BP) algorithm affected by erroneous data exchange in a wireless sensor network (WSN). The WSN conducts a distributed multidimensional hypothesis test over binary random variables. The joint statistical behavior of the sensor observations is modeled by a Markov random field whose parameters are used to build the BP messages exchanged between the sensing nodes. Through linearization of the BP message-update rule, we analyze the behavior of the resulting erroneous decision variables and derive closed-form relationships that describe the impact of stochastic errors on the performance of the BP algorithm. We then develop a decentralized distribute…

Linguistic Aspects in Web Counselling

2013

The global net system has provided new and expanded means of communication incorporating all forms of discourse, including medical interaction. However, due to the tentative nature of medical discourse, online relations between professionals and their patients still encounter limitations. Standard procedures between the doctor and patient allowed the doctor to assume an authoritative role as his position provided personal remedy or advice to the patient at hand. Consequently, he was relied upon to solve the initial complaint, and this capacity rendered the patient as the dependent party. The responsibility of this exchange was to counsel, and the doctor was therefore required to use accessi…
