Ko atklāj Ķīnas Ceļa un jostas iniciatīvas investīcijas? Nestriktas kopas kvalitatīvā salīdzinošā analīze
2020
Maģistra darbā “Ko atklāj Ķīnas Ceļa un jostas iniciatīvas investīcijas? Nestriktas kopas kvalitatīvā salīdzinošā analīze” tika analizēts Ķīnas Ceļa un jostas iniciatīvas (BRI) investīciju daudzums 78. Eirāzijas valstīs, lai noteiktu, kādi valstis raksturojoši faktori vai apstākļi ietekmē to vēlmi pievienoties BRI. Izvēlētajām valstīm pēc detalizētas pētnieciskās literatūras analīzes tika noteikti astoņi investīcijas veicinošie faktori (gan politiskie, gan ekonomiskie). Izvēlētie faktori tika pretnostatīti Ķīnas BRI investīciju apjomam uz vienu iedzīvotāju konkrētā valstī, lai varētu secināt, kādi valsti raksturojoši apstākļi un priekšnoteikumi veicina Ķīnas BRI investīciju plūsmu uz konkrē…
Relationships among Bicycle Rider Behaviours, Anger, Aggression, and Crashes in Finland
2022
Riding a bicycle is increasingly encouraged as a sustainable transport solution, especially in urban areas. However, safety concerns, both perceived and actual, can significantly lower the willingness to ride among the population. To support cycling planning and policy in the double task of increasing the levels of cycling while mitigating crash risk, there is a need to better understand the behaviours and attitudes of bicycle riders. In this manuscript, we study a cohort of Finnish bicycle riders through four questionnaires, the Cycling Behaviour Questionnaire (CBQ), Cyclist Risk Perception and Regulation Scale (RPRS), Cyclist Anger Scale (CAS), and Cyclist Aggression Expression Inventory …
Eiropas Savienība un Ķīnas Jaunā Zīda Ceļa Iniciatīva: iespējas un izaicinājumi
2017
Jaunā Zīda Ceļa Iniciatīva, kuru 2013. gadā ierosināja Ķīna ar galveno mērķi savienot lielākās Eirāzijas ekonomikas, izmantojot infrastruktūru, tirdzniecību un investīcijas. Šī ir lielākā un nozīmīgākā Ķīnas ekonomiskā stratēģija 21. gadsimtā, kura tieši ietekmēs ES un it īpaši Centrāleiropas un Austrumeiropas valstis. Šobrīd Eiropas Savienībā ir daudz neatrisinātu, attīstību kavējošu faktoru kā nelīdzsvarots attīstības līmenis starp tās dalībvalstīm, finanšu krīzes atskaņas, grūti prognozējama bēgļu un nelegālās migrācijas situācija, pasliktinātas attiecības ar Krieviju, Breksits, un nenoteiktība ar TTIP tālāko attīstību, ņemot vērā jauno ASV valdību. Pēc autora domām, Ķīnas kompānijām pie…
Intellectual Structure of the Belt and Road Initiative Research: A Scientometric Analysis and Suggestions for a Future Research Agenda
2020
China’s Belt and Road Initiative (BRI) has attracted increasing attention worldwide since its inception in 2013. Although the research is fast increasing in terms of publications, there is a lack of knowledge about the intellectual structure, research trends, and appropriate theories underpinning. Using bibliometric data from 1583 articles from 2013 to 2019 in the Web of Science and Scopus databases, we used bibliometric techniques and scientometric analyses to identify and analyze the intellectual structure, hotspots, and emerging trends in this field. We identified 18 clusters that we categorized into three groups for thematic discussion. Research gaps and future research directions were …
Development of “New Silk Road” Northern Branch through Seaport of Riga in Latvia
2014
Abstract The study reveals opportunity to develop the “New Silk Road” Northern branch from North-West China (the People's Republic of China) via seaport of Riga in Latvia to Europe. The methods of the study are the monographic method, the statistical analysis, the expert method and a case study. The study shows that the shortest route for the “New Silk Road” Northern branch is through seaport of Riga (Latvia) which is the shortest way from China to the seaport in the European Union. The existing railway infrastructure can be used from Urumqi (North-Western China) to the seaport of Riga. Transit countries for this route are Kazakhstan and Russia. This route could be beneficial for distributi…
Grounds and Challenges for Implementing a Circular Economy in the European Road transport Sector
2017
Environmental challenges, especially in the form of resource depletion, pollution and greenhouse gas emission, are very important challenges for the socio-economic development. For this reason, the concept of a circular economy has been developed and is being implemented in different areas. In 2015, the European Union adopted the Circular Economy Package consisting of an “EU Action Plan for the Circular Economy”, presenting a set of actions aimed at achieving objectives of the circular economy in Europe. The goal of the paper is to describe and discuss key challenges facing implementation of the concept of the circular economy in the European road transport sector. First, the concept of a c…
European National Road Authorities and Circular Economy: An Insight into Their Approaches
2020
The pavement engineering industry, having realized the significance of the impacts that it imposes on the environment through the production, construction and management of its products and assets, has been driven towards a more sustainable and circular way of operating. This has partly been through asphalt recycling, which is an area that many road authorities have prioritized. However, not all the National Road Authorities (NRAs) and/or sector stakeholders seem to be adequately familiar with the Circular Economy (CE) concept. This paper attempts to assist the transition of NRAs to a more circular way of doing business, by analyzing the current situation of CE within national/regional auth…
PV-Alert: A fog-based architecture for safeguarding vulnerable road users
2017
International audience; High volumes of pedestrians, cyclists and other vulnerable road users (VRUs) have much higher casualty rates per mile; not surprising given their lack of protection from an accident. In order to alleviate the problem, sensing capabilities of smartphones can be used to detect, warn and safeguard these road users. In this research we propose an infrastructure-less fog-based architecture named PV-Alert (Pedestrian-Vehicle Alert) where fog nodes process delay sensitive data obtained from smartphones for alerting pedestrians and drivers before sending the data to the cloud for further analysis. Fog computing is considered in developing the architecture since it is an emer…
Numerical simulation of radiated EMI in 42V electrical automotive architectures
2006
The work is focused on the evaluation of radiated electromagnetic interference generated by dc/dc converters in 42 V systems automotive environment. The results obtained by using the method of moments and the finite difference time domain method, separately, are presented and validated in comparison with those measured in a semi-anechoic electromagnetic chamber. A measurement system set up by the authors is employed. Both the used numerical approaches are proved to be an useful tool for radiated disturbance prediction, and also for electromagnetic compatibility oriented design of the vehicle electrical architecture.
