Besides, more traditional forms of human smuggling and trafficking, a new phenomenon has emerged especially along the Central Mediterranean route, i.e. <i>trafficking in itinere,</i> which affects people who had originally sought irregular travel services but then ended up in being kidnapped, tortured and kept in detention centres during their migratory path. Therefore, their irregular journey to Europe becomes the only way to survive. The methodology adopted draws from in-depth interviews with experts in Italy - especially prosecutors, law enforcements officers, representatives of NGOs and journalists -, the analysis of institutional reports and sources, as well as biographical accounts provided by migrants. The analysis critically addresses the countereffects produced by the hardening of borders and militarisation of sea routes in the Mediterranean area especially in terms of enhancement of the smuggling industry, increased human rights violations and clandestinization of migrants whose experiences and knowledge are too often underrepresented or misrepresented in the public debate. This results in a negative impact on migration policy-making and on the adoption of more effective measures aimed at addressing the governance of borders and the reception system in the EU. In conclusion, some recommendations are made, which call for a reconsideration of the distinction between <i>economic</i> and <i>political</i> migrants, an enhancement of the right to migrate which can guarantee safer forms of mobility toward the EU, a serious reconsideration of the politics of externalization of European borders with its extremely severe costs in terms of human rights, and a stronger valorisation of migrants' actual needs, expectations and projects in the design of more effective policies aimed at improving the overall EU reception system.</p>","PeriodicalId":74359,"journal":{"name":"Open research Europe","volume":"4 ","pages":"126"},"PeriodicalIF":0.0,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11574331/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142677988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EXPLORE Machine Learning Lunar Data Challenge was a public initiative during the last quarter of 2022. Its objective was to encourage participants to apply machine learning techniques to identify potential hazards for a planetary mission and to design a robotic traverse for exploring the lunar surface. Methods The lunar region targeted by the challenge was the Archytas Dome in Mare Frigoris, a location with a varied geology and a potential zone for future exploration. We provided training datasets of craters and boulders to the participants, who used them to complete the three steps of the challenge: creating a model that detects these landforms, applying these models to the Archytas Dome region, and computing a traverse for optimal exploration of the zone. In this paper, we showcase the results and considerations of the team that won the challenge. The first step was to enhance the training data by generating new labels and resizing the existing ones. The original and the improved dataset were then used to train four iterations of a neural network model. Results The model with the enhanced dataset yielded the best scores when applied to the Archytas Domes zone (75.46%). Finally, the traverse was calculated using proximity analysis while avoiding steep slopes and dangerous landforms. Conclusions We found that the variations between tasks and the different approaches necessary to solve them turned out to be the major difficulty of the challenge, as it required backgrounds in both remote sensing and computer sciences. This was reflected in the low participation and the multidisciplinary of the members of the winning team.","PeriodicalId":74359,"journal":{"name":"Open research Europe","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141348022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All the groups took part in eight-hour training, which includes one introductory module that introduces the mental health topic alongside a five-step model of UMHT, two disorders-focused modules with the steps adjusted to work with specific disorders, and the final module that considers possible difficulties frontline professionals might experience. Three effectiveness measurements were used in the outcome assessment: readiness to interact with people with mental health issues at work, mental health awareness and mental health proficiency.</p><p><strong>Results: </strong>Analysis of the outcome data for the frontline professionals who underwent the UMHT revealed a moderate effect size related to the knowledge of mental health conditions, mental health awareness, and increasing the readiness to interact with people with mental health issues in comparison to the control group.</p><p><strong>Conclusions: </strong>High-level utilisation of the UMHT at work by trained professionals confirms the effectiveness of the developed intervention. Obtained results favour the continuation of the development of the UMHT and future implementation research in this field in Ukraine and potentially in other low- and middle-income countries.</p>","PeriodicalId":74359,"journal":{"name":"Open research Europe","volume":"4 ","pages":"19"},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11249520/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141629478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
