New attempts at Electronic Documents in Transport. Bolero - the end of the experiment, the beginning of the future?
No full textIn this thesis the author examines a 'revolution' taking place in the shipping industry brought on by the development of computerisation, electronic commerce and the change from paper documentation to electronic documentation in the carriage of goods by sea. The focus of the paper is on Bolero, a project of the European Community beginning in the early 1990s and which has been used commercially since September 1999. In this paper the author follows the Bolero project from its inception as an experiment through to its commercial application. The question is asked to what extent Bolero has become an alternative to, or in fact replaced paper documentation in the carriage of goods by sea. As an introduction the author looks at the paper bill of lading and other forms of sea transport documentation with a focus on their advantages and disadvantages. He then examines the development of EDI and paperless sea transport documentation, in particular Bolero and the history of its development. Following this is an in depth investigation of the Bolero system in its current form, the contractual relations involved and the position of Bolero in the surrounding legal framework in a South African and international context. Finally the author looks at the future of Bolero as a commercial enterprise
HANSEN: Human and AI Spoken Text Benchmark for Authorship Analysis
No full textAuthorship Analysis, also known as stylometry, has been an essential aspect of Natural Language Processing (NLP) for a long time. Likewise, the recent advancement of Large Language Models (LLMs) has made authorship analysis increasingly crucial for distinguishing between human-written and AI-generated texts. However, these authorship analysis tasks have primarily been focused on written texts, not considering spoken texts. Thus, we introduce the largest benchmark for spoken texts - HANSEN (Human ANd ai Spoken tExt beNchmark).
HANSEN encompasses meticulous curation of existing speech datasets accompanied by transcripts, alongside the creation of novel AI-generated spoken text datasets. Together, it comprises 17 human datasets, and AI-generated spoken texts created using 3 prominent LLMs: ChatGPT, PaLM2, and Vicuna13B. To evaluate and demonstrate the utility of HANSEN, we perform Authorship Attribution (AA) & Author Verification (AV) on human-spoken datasets and conducted Human vs. AI spoken text detection using state-of-the-art (SOTA) models. While SOTA methods, such as, character ngram or Transformer-based model, exhibit similar AA & AV performance in human-spoken datasets compared to written ones, there is much room for improvement in AI-generated spoken text detection. The HANSEN benchmark is available at: https://huggingface.co/datasets/HANSEN-REPO/HANSEN
Technologies Immersives dans la Formation Professionnelle au Maroc : Étude de Cas de l'OFPPT
No full textCet article explore l'intégration des technologies de la réalité augmentée (RA) et de la réalité virtuelle (RV) dans les programmes de formation professionnelle au Maroc, en se concentrant sur le cas de l'OFPPT (Office de la Formation Professionnelle et de la Promotion du Travail). À travers une approche théorique basée sur l'analyse documentaire et la revue de littérature, l'article examine les avantages, les défis et les applications pratiques de ces technologies dans divers secteurs, notamment le Bâtiment et les Travaux Publics (BTP) et la Santé.
Les résultats montrent que l'utilisation des casques RA et RV, tels que Magic Leap et Oculus, améliore l'engagement des apprenants, la rétention des connaissances et la confiance dans l'application des compétences. Cependant, des défis persistent, tels que les coûts initiaux élevés et la nécessité de former adéquatement les formateurs.
Des études de cas spécifiques et les résultats d'un questionnaire envoyé aux formateurs révèlent des insights précieux sur l'impact de ces technologies immersives et les stratégies pour optimiser leur utilisation

Antisemitism in Protectorate of Bohemia and Moravia
No full textThe master thesis called "Antisemitism in the Protectorate of Bohemia and Moravia" is describing, based on historical events, progress of solution of the Jewish question in the occupied Czech lands during the Second world war. In the first chapter the author describes the main events of the Jewish minority life in the protectorate. Jews had lost all their personal rights and discrimination in this regard was almost unbearable. German Nazism developed and at the same time realized "final solution" of the Jewish question. This term signified euphemistic name for the physical extermination of the Jewish nation. The second chapter devotes to the analysis of the press. The most important part of the whole thesis introduces three collaborationist periodicals from protectorate, which were chosen by author. They are called: Zteč (Assault), Árijský boj (Arya fight) and Národní politika (National politics). Construction of the Terezin concentration camp and subsequent life in it describes the last and the third chapter. This ghetto meant an important part of the whole Jewish question and its solution. Although the transports to eastern areas took place here, some Jews arranged better life through cultural activities and illegal educational activities. One of the specifics of Terezín was also the role that the camp played in the Nazi propaganda
Challenges and opportunities of business models in sustainable transitions: Evidence from solar energy niche development in Lebanon
No full textAlthough business models presumably have a prominent role in socio-technical change remarkably little research has been conducted in this domain, more particularly in the context of developing economies. In this paper, we tap into this knowledge gap and study business model components and the challenges they face. We argue that the market value of renewable energy technologies will increase when new business models are implemented to overcome financial and institutional challenges. We complement concepts of the business model literature with the insights from the sustainable transitions literature. This paper addresses two research questions: What are the challenges of business and financial models in the transition towards decentralized solar energy driven systems? And what are the promising opportunities for new business models in a developing country context? To answer these research questions, we use a case study research design focusing on niche market development of solar thermal and solar photovoltaic (PV) technology in Lebanon. Data collection involved analysis of relevant text documents and expert interviews with 30 informants across different groups of stakeholders. Data analysis involved qualitative interpretation of collected data against concepts from the business model and Strategic Niche Management literatures. The results show that business model challenges initially were highly dependent on donor aid, which contributed to the launch and network creation of niche markets. Later, a shift to micro-finance and business startup models was observed, which showed promising development. Knowledge transfer and community empowerment were found to play an important role in developing new business models that involve consumers more closely. As this development is expected to take place more often, we expect that new opportunity pathways will develop in developing economies like Lebanon.Organisation & Governanc
