Lessons Learned from Honeypots - Statistical Analysis of Logins and Passwords
No full textPart 3: Security and Privacy IssuesInternational audienceHoneypots are unconventional tools to study methods, tools and goals of attackers. In addition to IP addresses, timestamps and count of attacks, these tools collect combinations of login and password. Therefore, analysis of data collected by honeypots can bring different view of logins and passwords. In paper, advanced statistical methods and correlations with spatial-oriented data were applied to find out more detailed information about the logins and passwords. Also we used the Chi-square test of independence to study difference between login and password. In addition, we study agreement of structure of password and login using kappa statistics

Normative Reasons : Between Reasoning and Explanation
No full textReasons matter greatly to us in both ordinary and theoretical contexts, being connected to two fundamental normative concerns: figuring out what we should do and what attitudes to have, and understanding the duties and responsibilities that apply to us. This book introduces and critiques most of the contemporary theories of normative reasons considerations that speak in favor of an action, belief, or emotion - to explore how they work. Artūrs Logins develops and defends a new theory: the Erotetic view of reasons, according to which normative reasons are appropriate answers to normative why questions (Why should I do this?). This theory draws on evidence of how why-questions work in informal logic, language and philosophy of science. The resulting view is able to avoid the problems of previous accounts, while retaining all of their attractive features, and it also suggests exciting directions for future research. This title is also available as Open Access on Cambridge Core

No full text“Veselības veicināšana biroja darbiniekiem, izmantojot mobilās aplikācijas”. Darba autore: Līga Riekstiņa. Darba zinātniskais vadītājs: doc., Dr. chem. Jāzeps Logins. Darbs izklāstīts uz 91 lappuses, ietver 47 attēlus, 16 tabulas, 4 pielikumus, 46 informatīvos avotus. Pētījums sastāv no 4 daļām. Pirmajā daļā analizēta literatūra par biroja darba vides riskiem, darbinieku veselības problēmām, veselības veicināšanas pasākumiem un veselību veicinošām mobilajām aplikācijām. Otrajā daļā aprakstītas pētījumā izmantotās metodes. Trešajā daļā atspoguļoti iegūtie rezultāti, un rezultātu analīze. Izstrādāti pamatoti preventīvie un aizsardzības pasākumi, izklāstītas praktiskās rekomendācijas. Biroja darbinieki neveic atslodzes vingrinājums darba laikā, tāpēc darba mērķis ir petīt mobilo aplikāciju izmantošanas iespējas biroja darbinieku veselības veicināšanā. Pēc risku novērtēšanas rezultātiem tika izstrādāta mobilā aplikācija ar atgādinājuma funkciju, kas dot norādes dažādu atslodzes vingrinājumu veikšanai. Pētījuma rezultātā izvirzītā hipotēze apstiprinās – lietojot veselību veicinošas mobilās aplikācijas, uzlabojas biroja darbinieku fiziskā un garīgā labizjūta. Izmantotās metodes: Somijas 5 baļļu metode, darbspēju indekss, ergonomisko risku ātrā ekspozīcijas kontrole, psiholoģiskā klimata darba vidē novērtēšanas metode, darbinieku aptauja, mobilo aplikāciju aprobācijas anketa.“Health promotion for office employees using mobile applications”. The author: Līga Riekstiņa. Research supervisor. Doc, Dr. Chem. Jāzeps Logins. The master’s thesis consists of 91 pages, includes 47 pictures, 16 tables, 4 attachments, 46 information sources. Research consists of 4 chapters. In the first chapter, the author viewed and analysed literature about office employee work environment risks, health problems, health promotion and health-promotion mobile applications. In the second chapter, the author described methods applied in the research. In the third chapter, the author described and analysed the results. In the framework of the master’s thesis, the author described practical recommendations and developed preventive and protective measures to promote health of persons who work in an office. Office workers do not perform exercises during working hours, so the master’s thesis aims to explore the possibilities of mobile applications use to promote health of the office employees. According to the results of the risk assessment, mobile application with a reminder function was developed that gives instructions for carrying out a variety of relaxation exercises. The hypothesis of the master’s thesis was confirmed – the use of health promoting mobile applications are improving physical and mental wellbeing of employees. Methods used : Finland’s 5 scale method, Work Ability Index, ergonomic risk Quick Exposure Check (QEC), approach for evaluating psychological climate of the working environment, employee survey, Mobile Application approbation questionnaire

Understanding Electrolytic Dissociation in a Digital Teaching and Learning Process
No full textElektrolītiskās disociācijas apguve digitalizētā ķīmijas mācību procesā. Marta Podniece, darba vadītājs: Vad. pētn. Dr. chem. Jāzeps Logins. Skolotāja pieredzes darbs, 38 lappuses, 7 attēli, 2 tabulas, 33 literatūras avoti, 5 pielikumi. Latviešu valodā. Pieredzes darbā “Elektrolītiskās disociācijas apguve digitalizētā ķīmijas mācību procesā” tiek pētīta un aprobēta digitālo rīku izmantošana, lai sekmētu mācību satura apguvi par elektrolītisko disociāciju vidusskolas ķīmijas stundās. Darbā analizēti temata plānošanas, organizēšanas, vērtēšanas un profesionālās pieredzes aspekti, balstoties uz teorētiskām atziņām, praktiskiem piemēriem un skolēnu aptaujas atsauksmēm. Pētījuma rezultāti rāda, ka digitālās simulācijas un interaktīvie uzdevumi palīdz skolēniem apgūt sarežģītus ķīmijas jēdzienus, vienlaikus samazinot materiālu izmaksas un novēršot drošības riskus. Tiek secināts, ka, neskatoties uz tehnoloģiskajiem izaicinājumiem un atšķirīgo skolēnu motivāciju, digitalizēts mācību process gan uzlabo skolēnu iesaisti un satura apguvi, gan tiek dažādots mācību process.

Marta Podniece, Diploma Paper Supervisor: Assistant Professor, Dr.chem. Jazeps Logins. Teachers experience work, 38 pages, 7 images, 2 tables, 33 literature sources and 5 attachments. In Latvian. Experience in the work “Understanding Electrolytic Dissociation in a Digital Teaching and Learning Process”, explores and tests the use of digital tools to enhance students understanding of electrolytic dissociation in upper secondary school chemistry lessons. The paper analyzes aspects of lesson planning, organization, assessment and professional experience, drawing on theoretical insights, practical examples, and student survey feedback. The results show that digital simulations and interactive tasks help students gain deeper understanding of complex chemistry concepts while reducing material costs and safety risks. The author concludes that, despite technological challenges and varying student motivation, a digitalized learning process is effective and improves both student engagement and understanding of the material and lesson curriculum variability.

Smartphones for Migrant Integration: A Lifeline, Bridging or Surveillance tool? Migrants’ perceptions of surveillance and social logins in mobile resources
No full textSweden is a highly digitalized society, rapidly changing into a multicultural one. Though migrants use smartphones in their migration journeys and, upon reaching host societies, for integration, i.e. learning language, culture and developing contacts with locals, there are certain potential risks in relation to surveillance. This study explores the use of mobile resources for integration purposes by newly arrived migrants in Sweden, in particular from the perspective of surveillance. Further, it aims to analyze the available mobile resources for migrant integration and how these resources are designed, with special focus on the use of social logins. Mapping of mobile resources in combination with 15 focus-group interviews with newly arrived migrants is used. The results show that the migrants are concerned about surveillance and consciously avoid using the resources in which social logins are required, preferring email as a sign-in option. The mapping of the resources shows that the majority of the resources have multiple sign-in options, including Facebook, Google and email. None has a social login as a sole sign-in, and many resources require no sign-in. Thus, the existing resources pose no apparent risk from the social media surveillance perspective for the migrants to use them. However, as in further development of resources social logins might become needed to track user progress, migrants’ concerns about surveillance should be taken into consideration
