The impact of mobile network forensics evidence on the criminal case processing performance in Macedonia: An institutional analysis study
Get PDFThe purpose of this study was to explore the contribution of the localization data, network-management data, and content-of-communication data in the case processing performance in Macedonia. The mobile network forensics evidence was analyzed respective to the impact of the mobile network data variety, the mobile network data volume, and the forensic processing on the case disposition time. The results from this study indicate that the case disposition time is negatively correlated with the network-management data volume and positively correlated with the content-of-communication data volume. The relevance of the network-management data was recognized in the highly granular service behavior profile developed using larger number of records, while the relevance of the content-of-communication data was recognized in the substantial number of excerpts of intercepted communication. The results also reveal a difference in the case processing time for the cases where there is only localization or network-management data versus when they are combined with the content-of-communication data
Fight Fire with Fire: Hacktivists' Take on Social Media Misinformation
Get PDFIn this study, we interviewed 22 prominent hacktivists to learn their take on
the increased proliferation of misinformation on social media. We found that
none of them welcomes the nefarious appropriation of trolling and memes for the
purpose of political (counter)argumentation and dissemination of propaganda.
True to the original hacker ethos, misinformation is seen as a threat to the
democratic vision of the Internet, and as such, it must be confronted on the
face with tried hacktivists' methods like deplatforming the "misinformers" and
doxing or leaking data about their funding and recruitment. The majority of the
hacktivists also recommended interventions for raising misinformation literacy
in addition to targeted hacking campaigns. We discuss the implications of these
findings relative to the emergent recasting of hacktivism in defense of a
constructive and factual social media discourse
Rules of professional responsibility in digital forensics: A comparative analysis
Get PDFThe consolidation of the rules of professional responsibility as recommended by the Committee on Identifying the Needs of Forensic Sciences Community (2009) accents the establishment of an uniform code of ethics emphasizing the importance of enforceability in strengthening the role the forensic science plays within the criminal justice system. Equally pertinent for the domain of digital forensics, this imperative entails a research commitment in comparing and contrasting the respective codes of ethics to illustrate their “variety, specificity and enforceability” in order to inform the discussion on the regulative aspects of the digital forensic discipline. Accordingly, this paper reviews the professional responsibility regulation inaugurated in both the US and international digital forensics arena aiming to bring give a closer and more detailed perspective on the practice harmonization within the digital real
Children, Parents, and Misinformation on Social Media
Get PDFChildren encounter misinformation on social media in a similar capacity as
their parents. Unlike their parents, children are an exceptionally vulnerable
population because their cognitive abilities and emotional regulation are still
maturing, rendering them more susceptible to misinformation and falsehoods
online. Yet, little is known about children's experience with misinformation as
well as what their parents think of the misinformation's effect on child
development. To answer these questions, we combined a qualitative survey of
parents (n=87) with semi-structured interviews of both parents and children
(n=12). We found that children usually encounter deep fakes, memes with
political context, or celebrity/influencer rumors on social media. Children
revealed they "ask Siri" whether a social media video or post is true or not
before they search on Google or ask their parents about it. Parents expressed
discontent that their children are impressionable to misinformation, stating
that the burden falls on them to help their children develop critical thinking
skills for navigating falsehoods on social media. Here, the majority of parents
felt that schools should also teach these skills as well as media literacy to
their children. Misinformation, according to both parents and children affects
the family relationships especially with grandparents with different political
views than theirs
Older Adults' Experiences with Misinformation on Social Media
Get PDFOlder adults habitually encounter misinformation on social media, but there
is little knowledge about their experiences with it. In this study, we combined
a qualitative survey (n=119) with in-depth interviews (n=21) to investigate how
older adults in America conceptualize, discern, and contextualize social media
misinformation. As misinformation on social media in the past was driven
towards influencing voting outcomes, we were particularly interested to
approach our study from a voting intention perspective. We found that 62% of
the participants intending to vote Democrat saw a manipulative political
purpose behind the spread of misinformation while only 5% of those intending to
vote Republican believed misinformation has a political dissent purpose.
Regardless of the voting intentions, most participants relied on source
heuristics combined with fact-checking to discern truth from misinformation on
social media. The biggest concern about the misinformation, among all the
participants, was that it increasingly leads to biased reasoning influenced by
personal values and feelings instead of reasoning based on objective evidence.
The participants intending to vote Democrat were in 74% of the cases concerned
that misinformation will cause escalation of extremism in the future, while
those intending to vote Republican, were undecided, or planned to abstain were
concerned that misinformation will further erode the trust in democratic
institutions, specifically in the context of public health and free and fair
elections. During our interviews, we found that 63% of the participants who
intended to vote Republican, were fully aware and acknowledged that Republican
or conservative voices often time speak misinformation, even though they are
closely aligned to their political ideology
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
Cyber Operations RangE (CORE): Containerized Gaming Platform for Cyberoperations Competitions
Get PDFCybersecurity gaming is popularized through capture-the-flag (CTF) competitions, war games, and forensic challenges. Providing actual hands-on experience, the cybersecurity competitions have great potential to support classroom learning, professional skill development, and scenario testing. To capitalize this, the supporting gaming platforms need to overcome the following issues: i) A complex virtualized infrastructure that requires extensive resources and administration, ii) Lack of support for real-time cyberoperations within a competition environment, and iii) implementation of independent, real-time scoring system which tracks progress and determines results of the competitors. In response to these issues, we have developed Cyber Operations RangE (CORE) - a containerized cybersecurity gaming platform. This paper presents the design, implementation, and the application of the CORE platform for real-time cyberoperations competitions
