UML Artefacts for a Blockchain-enabled Platform for Fairtrade

2021

Fairtrade-certified products have successfully entered the mainstream distribution channels mostly in developed countries, and these products are now sold in famous supermarket chains. Nonetheless, the packaging and labeling of products as “Fairtrade” commands premium pricing in the marketplace. How much of this, however, is valid and justified? Despite the reputable certification mechanisms for quality assurance, mass media reports suggest that much of the “surplus value” goes to the accreditation agencies themselves instead of the producers. This article proposes an agenda to set this right with a blockchain platform that provides “trust-free” assurances of verifiable labeling. Using an A…

Trusted Computing and DRM

2015

Trusted Computing is a special branch of computer security. One branch of computer security involves protection of systems against external attacks. In that branch we include all methods that are used by system owners against external attackers, for example Firewalls, IDS, IPS etc. In all those cases the system owner installs software that uses its own means to determine if a remote user is malicious and terminates the attack. (Such means can be very simple such as detecting signatures of attacks or very complex such as machine learning and detecting anomalies in the usage pattern of the remote user). Another branch of attacks requires protection by the system owner against internal users. …

A Conversational Agent Based on a Conceptual Interpretation of a Data Driven Semantic Space

2005

In this work we propose an interpretation of the LSA framework which leads to a data-driven “conceptual” space creation suitable for an “intuitive” conversational agent. The proposed approach allows overcoming the limitations of traditional, rule-based, chat-bots, leading to a more natural dialogue.

Redzes ietekme uz stāju

2017

Maģistra darbs ir uzrakstīts angļu valodā uz 45 lapām. Tas satur 28 attēlus un 40 literatūras atsauces. Darba mērķis bija izvērtēt optometriskās ārstēšanas ietekmi uz stājas izmaiņām. 11 pacientiem tika veikti mērījumi ar datorizētu stabilometrijas platformu pirms un pēc redzes treniņu veikšanas. Pacientam stāvot ar atvērtām acīm, pēc redzes treniņiem svara sadalījums bija sabalansētāks priekšēji-mugurējās ass virzienā, spiediena centrs nobīdījās tuvāk teorētiskajam centram, kā arī svārstību ātrums, amplitūda un laukums samazinājās. Pacientam stāvot ar aizvērtām acīm, nenovēroja nozīmīgas izmaiņas pirms un pēc ārstēšanas. Līdz ar to, redzes kvalitātes uzlabošana var tieši ietekmēt pacienta …

Formation and significance of black pebbles from the ota limestone (Upper Jurassic, Portugal)

1987

Black pebbles are a characteristic facies element of the Upper Jurassic Ota carbonate bank (Portugal). They occur both scattered or concentrated in two horizons, the upper of which is very widespread and may serve as a lithostratigraphic correlation level.

Critical Assessment of European Agenda for the Collaborative Economy, on behalf of European Parliament. In-Depth Analysis for the IMCO Committee

2017

The research paper describes the main legal challenges for regulating the collaborative economy and evaluates the definition of, and elucidates how the existing body of EU law applies to collaborative economy business models. In the last part, the paper elaborates on how a regulatory framework for non- professional provision of services and prosumers should look like and makes a few concrete proposals for future policies. This paper was commissioned by the Policy Department A for Economic, Scientific and Quality of Life Policies upon request of the European Parliament ́s Committee on the Internal Market and Consumer Protection.

Rinse, Repeat. Paratextual Poetics of Literary Twitter Collage Retweeted

2019

This essay studies what happens to the poetics of a text that was first written on or for a certain internet platform when it is later copy-pasted to a different literary medium – that of an edited and printed book. The main target of the discussion is Finnish author Karri Kokko’s conceptual literary work Retweeted (2016), a print-on-demand book, the roots of which are firmly in both the traditions of print media and the digital interfaces of the social media platform Twitter. The analysis pays close attention to the medial qualities of both Twitter and the conceptual novel that draws material from it. The essay aims to highlight the poetic qualities of the material produced and circulated …

Deregulated Splicing Is a Major Mechanism of RNA-Induced Toxicity in Huntington's Disease.

2019

Huntington's disease (HD) is caused by an expanded CAG repeat in the huntingtin (HTT) gene, translating into an elongated polyglutamine stretch. In addition to the neurotoxic mutant HTT protein, the mutant CAG repeat RNA can exert toxic functions by trapping RNA-binding proteins. While few examples of proteins that aberrantly bind to mutant HTT RNA and execute abnormal function in conjunction with the CAG repeat RNA have been described, an unbiased approach to identify the interactome of mutant HTT RNA is missing. Here, we describe the analysis of proteins that preferentially bind mutant HTT RNA using a mass spectrometry approach. We show that (I) the majority of proteins captured by mutant…

Platforma czasopism Uniwersytetu Opolskiego przykładem synergii w budowaniu otwartego dostępu do publikacji uczelnianych

2020

Narodowe Centrum Nauki we wrześniu 2018 r. zadeklarowało udział w realizacji Planu S, który przewiduje, że od 1 stycznia 2020 r. wszystkie publikacje naukowe powstałe z udziałem finansowania ze środków publicznych muszą być publikowane w czasopismach Open Access lub na platformach Open Access. Na Uniwersytecie Opolskim trwały już wtedy prace nad uruchomieniem platformy, która zapewniłaby otwarty dostęp do uczelnianych czasopism naukowych. Docelowo umieszczono na niej trzynaście tytułów wydawanych przez uczelnię. Zadanie to powierzono do realizacji Bibliotece Głównej UO jako jednostce koordynującej wszelkie prace związane z jej powstaniem. Jest to kolejna – po repozytorium uczelnianym – form…
