First Evidence of Contourite Drifts in the North-Western Sicilian Active Continental Margin (Southern Tyrrhenian Sea)

2021

We present the results of an integrated geomorphological and seismo-stratigraphic study based on high resolution marine data acquired in the north-western Sicilian continental margin. We document for the first time five contourite drifts (marked as EM1a, EM2b, EM2, EM3a, and EM3b), located in the continental slope at depths between ca. 400 and 1500 m. EM1a,b have been interpreted as elongated mounded drifts. EM1a,b are ca. 3 km long, 1.3 km wide, and have a maximum thickness of 36 m in their center that thins northwards, while EM1b is smaller with a thickness up to 24 m. They are internally characterized by mounded seismic packages dominated by continuous and parallel reflectors. EM2 is loc…

The Joint Distribution Criterion and the Distance Tests for Selective Probabilistic Causality

2010

A general definition and a criterion (a necessary and sufficient condition) are formulated for an arbitrary set of external factors to selectively influence a corresponding set of random entities (generalized random variables, with values in arbitrary observation spaces), jointly distributed at every treatment (a set of factor values containing precisely one value of each factor). The random entities are selectively influenced by the corresponding factors if and only if the following condition, called the joint distribution criterion, is satisfied : there is a jointly distributed set of random entities, one entity for every value of every factor, such that every subset of this set that corr…

Interlinked and integrated research support services

2022

This poster introduces the efficient set of research support services available in University of Jyväskylä’s (JYU) Open Science Centre (OSC). The set includes several essential services for researchers to help them execute an open and responsible research process.  The continuous improvement of research support services has led to an interlinked, integrated and harmonious set of technical solutions, processes and workflows which meet the needs of researchers and help them implement open science and FAIR policies in practice. They also save time and enable better working processes for the researchers but also for the experts conducting these services.  The poster describes two main services …

Detecting cellular network anomalies using the knowledge discovery process

2015

Analytical companies unanimously forecast the exponential growth of mobile traffic consumption over the next five years. The densification of a network structure with small cells is regarded as a key solution to meet growing capacity demands. The manual management of a multi-layer network is a very expensive, error prone, and sluggish process. Hence, the automation of the whole life cycle of network operation is highly anticipated. To this aim 3GPP introduces a self-management concept referred to as SON. It is envisioned that SON updates information concerning the latest network conditions through the MDT mecha- nism. MDT enables a network operator to collect radio and service quality measurem…

The Dynamic Relationship between Response Processes and Self-Regulation in Critical Thinking Assessments

2021

Our aim was to explore higher education students’ response and self-regulatory processes plus the relationship between these, as evidenced in two types of performance-based critical thinking tasks included in the Collegiate Learning Assessment (CLA+) International instrument. The data collection consisted of 20 cognitive laboratories. The data were analyzed using a qualitative approach. The tasks were found to trigger different response and self-regulatory processes. Overall, the performance task evoked more holistic processes than the selected-response questions, in which students’ processes were more question-oriented. The results also indicated the entanglement of students’ response and …

Infrastructural and Human Factors Affecting Safety Outcomes of Cyclists

2018

The increasing number of registered road crashes involving cyclists during the last decade, and the high proportion of road crashes resulting in severe injuries and fatalities among cyclists constitutes a global issue for community health, urban development, and sustainability. Nowadays, the incidence of many risk factors for road crashes of cyclists remains largely unexplained. Given the importance of this issue, the present study has been conducted with the aim of determining relationships between infrastructural, human factors and safety outcomes of cyclists. Objectives: This study aimed, first, to examine the relationship between key infrastructural and human factors present in cycling,…

Zināšanu krātuvju Wikidata un DBpedia salīdzinājums

2020

Zināšanu krātuves Wikidata un DBpedia ir divi saistīti un līdzīgi, savstarpēji papildinoši, bet joprojām atšķirīgi projekti, kuru mērķis ir saglabāt pēc iespējas vairāk zināšanu par cilvēkam pazīstamām lietām strukturētā veidā. Maģistra darba mērķis ir izpētīt un raksturot zināšanu krātuves Wikidata un DBpedia, salīdzinot to nolūku, uzbūvi un iespējas. Praktiskajā daļā tiek dots ieskats uz zināšanu krātuvēs Wikidata un DBpedia glabātu zināšanu iegūšanas pieeju, kā arī tiek novērtēts iegūto datu pilnīgums un kvalitāte.

Wikidata un Wikimedia Commons strukturēto datu izpēte un pielietojums

2021

Semantiskā tīmekļa izstrāde un pētniecība ir radījusi pavērsienu tīmekļa tehnoloģiju jomā, kā rezultātā ir radušās jaunas un noderīgas tehnoloģijas kā saistīto datu zināšanu krātuves. Bakalaura darba mērķis ir izpētīt Wikidata un Wikimedia Commons zināšanu krātuvju strukturētos datus un to pielietojumu. Wikidata ir atvērta cilvēku sadarbībā izstradāta daudzvalodu saistīto datu kopa ar galveno mērķi nodrošināt strukturētus datus Wikimedia projektiem. Wikimedia Commons ir apjomīga kolekcija ar strukturētām, brīvi pieejamām multivides datnēm, kas ir galvenais vizuālo materiālu resurss tādiem projektiem kā Wikipedia un Wikidata. Pētījuma ietvaros tika izstrādāta tīmekļa lietone, kas sniedz iesp…

Starting a new business later in life

2014

Self-employment in later life may be either a career option or a form of partial retirement. This paper adds knowledge about those individuals who start a business when they are older. A large longitudinal data set is utilized to examine the transitions of individuals aged 55–74 to self-employment in Finland. The significance of prior activity as well as personal, household, financial, and environmental characteristics is analyzed for the transitions. The results show that most of those entering self-employment in later life have prior self-employment experience, thus suggesting that entrepreneurship at later ages is often habitual. Habitual entrepreneurs deviate from novice entrepreneurs i…
