Undersökning av Tonåringars Användarsäkerhet på Sociala Medier
No full textI den digitala tidsåldern har sociala medieplattformar blivit en integrerad del av tonåringarsdagliga liv, och erbjuder möjligheter för kommunikation, självuttryck och social interaktion. Mendenna utbredda användning utsätter också tonåringar för olika säkerhetsrisker. Denna studieundersöker medvetenheten om dessa säkerhetsrisker bland svenska tonåringar i åldrarna 13 till19 och identifierar de säkerhetsmekanismer de använder eller är medvetna om. Med hjälp av enblandad metod kombinerar forskningen kvantitativ data från undersökningar med kvalitativadata från semi-strukturerade intervjuer. Resultaten avslöjar att även om ett betydande antaltonåringar är medvetna om potentiella onlinehot, finns det en diskrepans mellan derasmedvetenhet och proaktiva engagemang i säkerhetspraxis. Socialt inflytande, särskilt frånkamrater och familj, spelar en avgörande roll för att forma deras onlinesäkerhetsbeteenden.Dessutom belyser studien behovet av skräddarsydda utbildningsinitiativ som inte bara ökarmedvetenheten utan också utrustar tonåringar med praktiska färdigheter för att navigera i detdigitala landskapet på ett säkert sätt. Rekommendationer för att förbättra digital kompetensgenom skolprogram och föräldrarnas engagemang diskuteras, tillsammans med förslag påframtida forskning.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Automated Detection of Vulnerabilities in ERC20-based Smart Contracts : Using Fuzzing, Symbolic Execution and Static Analysis in Ethereum-based Environments
No full textThe security of smart contracts deployed on Ethereum-based environments is a growing concern, especially as these contracts increasingly govern critical operations in decentralized applications. Traditional manual auditing methods are often time-consuming, error-prone, and insufficient to detect complex or deeply embedded vulnerabilities. This paper proposes an automated approach to detect vulnerabilities in Ethereum smart contracts through the integration of fuzzing and symbolic execution techniques. The framework combines property-based fuzzing using Echidna with symbolic execution via Mythril and static analysis via Slither to enhance vulnerability coverage. The goal is to identify common vulnerabilities such as re-entrancy, integer overflows, access control misconfigurations, and unchecked external calls. A comprehensive evaluation is conducted on smart contracts sourced from open datasets such as verified Etherscan repositories. The results are assessed based on detection accuracy, false positive and negative rates, code coverage, and execution time. This research demonstrates that combining fuzzing, symbolic execution, and static analysis in an automated pipeline provides a robust foundation to improve smart contract security in Ethereum ecosystems
