Universal design for website authentication:views and experiences of senior citizens

Using digital devices and online products and services requires users to regularly authenticate themselves. Given that the vast majority of websites use passwords to authenticate users, this study focuses on the accessibility and inclusivity of this mechanism, using Universal Design Principles as a lens. Collecting and analysing autobiographical narrative data from 50 respondents, we use a qualitative approach to explore the views and experiences of senior citizens across various phases of website authentication. Our analysis uncovers barriers and challenges, leading to several undesirable consequences, when authentication is not accessible and inclusive. Our findings also show how users, many of whom have cognitive and other age-related infirmities which are seldom accommodated in authentication design, try to cope with these issues. Our findings show how authentication may fail to align with the principles of universal design and highlight considerations in making authentication more accessible and inclusive for all users

SOK:young children’s cybersecurity knowledge, skills & practice: a systematic literature review

The rise in children’s use of digital technology highlights the need for them to learn to act securely online. Cybersecurity skills require mature cognitive abilities which children only acquire after they start using technology. As such, this paper explores the guidance and current curriculum expectations on cybersecurity aspects in Scotland. Additionally, a systematic review was undertaken of the literature pertaining to cybersecurity education for children on a wider scale including papers from around the world, with 27 peer reviewed papers included in the final review. We discovered that most research focused on assessing children’s knowledge or investigating the efficacy of interventions to improve cybersecurity knowledge and practice. Very few investigated the skills required to carry out the expected cybersecurity actions. For example, high levels of literacy, mature short- and long-term memory, attention, and established meta cognition are all pre-requisites to be able to carry out cybersecurity activities. Our main finding is that empirical research is required to explore the ages at which children have developed essential cognitive abilities and thereby the potential to master cybersecurity skills

Comparing Three Countries’ Higher Education Students’ Cyber Related Perceptions and Behaviours during COVID-19

In 2020, a global pandemic led to lockdowns, and subsequent social and business restrictions. These required overnight implementation of emergency measures to permit continued functioning of vital industries. Digital technologies and platforms made this switch feasible, but it also introduced several cyber related vulnerabilities, which students might not have known how to mitigate. For this study, the Global Cyber Security Index and the Cyber Risk literacy and education index were used to provide a cyber security context for each country. This research project—an international, cross-university, comparative, quantitative project—aimed to explore the risk attitudes and concerns, as well as protective behaviours adopted by, students at a South African, a Welsh and a Hungarian University, during the pandemic. This study’s findings align with the relative rankings of the Oliver Wyman Risk Literacy and Education Index for the countries in which the universities reside. This study revealed significant differences between the student behaviours of students within these universities. The most important differences were identified between students’ risk attitudes and concerns. It was also discovered that South African students reported having changed their protective online behaviours to the greatest extent, since the pandemic commenced. Recommendations are made suggesting that cyber security training and education, as well as improving the digital trust and confidence in digital platforms, are critical

UK cybercrime, victims and reporting : a systematic review

Individuals and organisations based in the United Kingdom often fall foul of cyber criminals. Unfortunately, these kinds of crimes are under-reported [66][115][123]. This under-reporting hampers the ability of crime fighting units to gauge the full extent of the problem, as well as their ability to pursue and apprehend cyber criminals [13][77]. To comprehend cybercrime under-reporting, we need to explore the nature of United Kingdom’s (henceforth: UK) cybercrime and its impact on UK-based victims. We investigated the entire landscape by carrying out a systematic literature review, covering both academic and grey literature. In our review, we sought to answer three research questions: (1) What characterises cybercrime in the UK? (2) What is known about UK cybercrime victims? and (3) What influences and deters cybercrime reporting in the UK? Our investigation revealed three types of reportable cybercrime, depending on the targets: (a) individuals, (b) private organisations, and (c) public organisations. Victimhood varies with various identified dimensions, such as: vulnerability aspects, psychological perspectives, age-related differences, and researcher attempts to model the victims of cybercrime. We also explored UK victims’ reported experiences in dealing with the consequences of falling victim to a cybercrime. In terms of cybercrime reporting, we identify three kinds of reporting: (a) Human-To-Human, (b) Human-To-Machine, and (c) Machine-To-Machine. In examining factors deterring reporting, we incorporate discussions of policing, and the challenges UK police forces face in coping with this relatively novel crime. Unlike traditional crimes, perpetrators possess sophisticated technological skills and reside outside of UK’s police jurisdiction. We discovered a strong social dimension to reporting incidence with the UK government‘s cyber responsibilization agenda likely playing a major role in deterring reporting. This strategy involves governments providing a great deal of advice and then expecting citizens to take care of their own cybersecurity. If they do not act on the advice, they should know that they will have to accept the consequences. Improvements in cybercrime reporting, to date, have been technologically focused. This neglects the social dimensions of cybercrime victimhood and does not acknowledge the reporting-deterring side effects of the UK's cyber responsibilization agenda. We conclude with suggestions for improving cybercrime reporting in the UK

Blinkered views of out-group mobile phone usage : moving towards less stereotyping of 'others'

Trainee designers, like other humans, often see the world through their own specific lenses. This can potentially negatively impact on their designs, especially if they design with users like themselves in mind. The purpose of the study reported in this paper was to expose students to the non-homogeneity of users from different out-groups, characterised by age differences. Student researchers were tasked to explore the mobile usages and perceptions of out-group members. The younger and older mobile phone users challenged the students’ preconceptions about how they would use their phones. This awareness is likely to translate into improved interface designs for users across the age spectrum

Deploying design science research in graduate computing studies in South Africa

Design science research is a relatively recent paradigm, which has enjoyed more acceptance in information systems than in computer science. Yet researchers are increasingly accepting this new paradigm where artifacts are to be developed to solve a problem, and the knowledge that is derived during the process is recorded and contributes to the field of knowledge. It is also particularly applicable in a developing world context. In this paper we present two case studies, demonstrating how two postgraduate students used design science research during their research. We reflect on the lessons learned and explain how design science research can be an attractive option for graduate student research at masters and doctoral level in both Information Systems and Computer Science

‘Lockdown' : digital and emergency eLearning technologies - a student perspective

As the digitalization process has become more and more important in our daily lives, during recent decades e-commerce has greatly increased in popularity, becoming increasingly used, therefore representing an extremely convenient alternative to traditional stores. In order to develop and maintain profitable businesses, traders need accurate forecasts concerning their future sales, a very difficult task considering that these are influenced by a wide variety of factors. This paper proposes a novel e-commerce sales forecasting method that dynamically builds a Directed Acyclic Graph Neural Network (DAGNN) for Deep Learning architecture. This will allow for long-term, fine-grained forecasts of daily sales revenue, refined up to the level of product categories. The developed forecasting method provides the e-commerce store owner an accurate forecasting tool for predicting the sales of each category of products for up to three months ahead. The method offers a high degree of scalability and generalization capability due to the dynamically incremental way in which the constituent elements of the DAGNN's architecture are obtained. In addition, the proposed method achieves an efficient use of data by combining the numerous advantages of its constituent layers, registering very good performance metrics and processing times. The proposed method can be generalized and applied to forecast the sales for up to three months ahead in the case of other e-commerce stores, including large e-commerce businesses

The Role of Eye Gaze in Security and Privacy Applications: Survey and Future HCI Research Directions

For the past 20 years, researchers have investigated the use of eye tracking in security applications. We present a holistic view on gaze-based security applications. In particular, we canvassed the literature and classify the utility of gaze in security applications into a) authentication, b) privacy protection, and c) gaze monitoring during security critical tasks. This allows us to chart several research directions, most importantly 1) conducting field studies of implicit and explicit gaze-based authentication due to recent advances in eye tracking, 2) research on gaze-based privacy protection and gaze monitoring in security critical tasks which are under-investigated yet very promising areas, and 3) understanding the privacy implications of pervasive eye tracking. We discuss the most promising opportunities and most pressing challenges of eye tracking for security that will shape research in gaze-based security applications for the next decade

Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome : Insights from the LUNG SAFE study

Publisher Copyright: © 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 ≥ 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort. Trial registration: LUNG-SAFE is registered with ClinicalTrials.gov, NCT02010073publishersversionPeer reviewe

Cabbage and fermented vegetables : From death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19

Large differences in COVID-19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe, or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage have been associated with low death rates in European countries. SARS-CoV-2 binds to its receptor, the angiotensin-converting enzyme 2 (ACE2). As a result of SARS-CoV-2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT(1)R) axis associated with oxidative stress. This leads to insulin resistance as well as lung and endothelial damage, two severe outcomes of COVID-19. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the most potent antioxidant in humans and can block in particular the AT(1)R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are: kimchi in Korea, westernized foods, and the slum paradox. It is proposed that fermented cabbage is a proof-of-concept of dietary manipulations that may enhance Nrf2-associated antioxidant effects, helpful in mitigating COVID-19 severity.Peer reviewe
