Data security in mobile healthcare
Introduction/purpose: The digitization of healthcare has gained particular importance in the years since the emergence of COVID-19 and also has become one of the primary goals of the Government of the Republic of Serbia. Telemedicine is a good solution when the patient cannot come to a healthcare facility. Mobile healthcare applications are already widely used, but in both fields the important challenge is data security. The aim of this paper is to review solutions for data security in mobile healthcare from the technical side and possible challenges in the process of digitization of the healthcare system in Serbia. Methods: This review is based on current papers in this area, on the available relevant literature and the authors' many years of experience in this field. Experiences in the process of digitization of healthcare in Serbia are based on available articles and regulations. Finally, possible challenges are presented from the authors' perspective based on everything presented in the field of data security in mobile healthcare. Results: The analysis of the papers reviewed from the point of view of data security showed that users are often ready to sacrifice their privacy for the sake of convenience provided by mobile applications. Conclusion: Based on the review of the papers and clear data security requirements that include the presented safeguards, one of the main tasks of the entire community is to raise awareness of information security and awareness of the need for cyber hygiene of each individual, which is the basis for the safe use of e-health services

The study used the descriptive exploratory approach and concluded that there is an effect of applying digital media tools according to the perceptions of journalists, and they focused on the reasons why most Jordanian media organizations are not ready to employ digital media techniques. In addition, the study indicated that there were Jordan journalists possessed various skills in digital media, including using social networks for research, writing, publishing news stories, and editing content
L’utilisation de dictionnaires de langues algonquiennes comme sources ethnographiques : étude de cas sur la culture légale et les pratiques juridiques illinoises au tournant du XVIIIe siècle
Abstract: Miami-Illinois is an Algonquian language that, in the 18th century, was to be heard to the south of the Great Lakes. In the 19th century, forced removals and the reservation system led to cultural and linguistic fragmentation amongst Miami-Illinois speakers. Against this current, language revitalization efforts began in the mid-1990s and, due to these, Miami-Illinois is again a spoken language. A wealth of documentation is now available through the Indigenous Languages Digital Archive. This thesis draws on this resource, in conjunction with other archival and published sources, to elicit an understanding of the legal culture of the people called Illinois by the French, particularly that of the Kaskaskias (kaahkaahkiaki), as it was in the early 18th century. Building on linguistic and historical sources, this work explores their jurispractice in relation to cases that have been preserved in the archives of the French overseas empire. Three points are addressed, namely: (i) how the Illinois (and Myaamia) thought about justice in the early 18th century; (ii) how the Miami-Illinois–and–French dictionaries can provide a new depth of understanding about this; and (iii) the limits to our ability to elicit abstract concepts from a fragmentary historical record.Au XVIIIe siècle, le miami-illinois (langue de la famille algonquienne) était traditionnellement parlée au sud des Grands Lacs. Le XIXe siècle a vu une fragmentation culturelle et linguistique parmi les locuteurs du miami-illinois. Des efforts de revitalisation de la langue ont commencé vers 1995. Grâce à ce travail minutieux, le miami-illinois est redevenu une langue parlée. Il y a maintenant une grande richesse de matériels linguistiques disponibles grâce à la banque de données Indigenous Languages Digital Archive. Cette thèse a pour but d’explorer la culture juridique des Illinois au début du XVIIIe siècle, avec une attention particulière pour le peuple kaskaskia (kaahkaahkiaki). En étudiant des cas réels préservés dans les archives de la Nouvelle France et en se basant sur des sources linguistiques et historiques, ce texte explore les pratiques juridiques des Illinois. Trois points sont étudiés : (i) la conception de la justice des Illinois (et Myaamia) au début du XVIIIe siècle; (ii) comment les dictionnaires jésuites en miami-illinois et français peuvent améliorer notre connaissance et compréhension de cette période; et (iii) les limites de la recherche dans l’histoire des idées dans les archives historiques incomplètes
FineIBT: Fine-grain Control-flow Enforcement with Indirect Branch Tracking
We present the design, implementation, and evaluation of FineIBT: a CFI
enforcement mechanism that improves the precision of hardware-assisted CFI
solutions, like Intel IBT and ARM BTI, by instrumenting program code to reduce
the valid/allowed targets of indirect forward-edge transfers. We study the
design of FineIBT on the x86-64 architecture, and implement and evaluate it on
Linux and the LLVM toolchain. We designed FineIBT's instrumentation to be
compact, and incur low runtime and memory overheads, and generic, so as to
support a plethora of different CFI policies. Our prototype implementation
incurs negligible runtime slowdowns (0%-1.94% in SPEC CPU2017 and
0%-1.92% in real-world applications) outperforming Clang-CFI. Lastly,
we investigate the effectiveness/security and compatibility of FineIBT using
the ConFIRM CFI benchmarking suite, demonstrating that our nimble
instrumentation provides complete coverage in the presence of modern software
features, while supporting a wide range of CFI policies (coarse- vs. fine- vs.
finer-grain) with the same, predictable performance
Ebony Magazine, the Editorial Left-Wing, and the Reshaping of Black Power in Post-War America, 1954-1998
This thesis explores the manner in which Ebony magazine, its owner John H. Johnson, and his left-wing editors sought to sell, intervene, advocate, and mainstream Black Power in post-war America. The dominant scholarly works have focused more broadly on the glamour of Ebony while overlooking the ways in which this magazine responded, reacted, and often overlapped with Black Power in the 1960s and 1970s. Such an endeavour was quarterbacked by its influential left-wing editors such as Lerone Bennett, David Llorens, and Phyl Garland. Their powerful position in Ebony and at the Johnson Publishing Company (JPC) propelled the magazine to act as a vital forum during Black Power and the modern black liberation struggle. By exploring its multifaceted responses to black activism and the modern black freedom movement in America, this thesis offers new insight into Ebony’s social standing in the post-war era
A Decision Support System for Economic Viability and Environmental Impact Assessment of Vertical Farms
Vertical farming (VF) is the practice of growing crops or animals using the vertical dimension via multi-tier racks or vertically inclined surfaces. In this thesis, I focus on the emerging industry of plant-specific VF. Vertical plant farming (VPF) is a promising and relatively novel practice that can be conducted in buildings with environmental control and artificial lighting. However, the nascent sector has experienced challenges in economic viability, standardisation, and environmental sustainability. Practitioners and academics call for a comprehensive financial analysis of VPF, but efforts are stifled by a lack of valid and available data.
A review of economic estimation and horticultural software identifies a need for a decision support system (DSS) that facilitates risk-empowered business planning for vertical farmers. This thesis proposes an open-source DSS framework to evaluate business sustainability through financial risk and environmental impact assessments. Data from the literature, alongside lessons learned from industry practitioners, would be centralised in the proposed DSS using imprecise data techniques. These techniques have been applied in engineering but are seldom used in financial forecasting. This could benefit complex sectors which only have scarce data to predict business viability.
To begin the execution of the DSS framework, VPF practitioners were interviewed using a mixed-methods approach. Learnings from over 19 shuttered and operational VPF projects provide insights into the barriers inhibiting scalability and identifying risks to form a risk taxonomy. Labour was the most commonly reported top challenge. Therefore, research was conducted to explore lean principles to improve productivity.
A probabilistic model representing a spectrum of variables and their associated uncertainty was built according to the DSS framework to evaluate the financial risk for VF projects. This enabled flexible computation without precise production or financial data to improve economic estimation accuracy. The model assessed two VPF cases (one in the UK and another in Japan), demonstrating the first risk and uncertainty quantification of VPF business models in the literature. The results highlighted measures to improve economic viability and the viability of the UK and Japan case.
The environmental impact assessment model was developed, allowing VPF operators to evaluate their carbon footprint compared to traditional agriculture using life-cycle assessment. I explore strategies for net-zero carbon production through sensitivity analysis. Renewable energies, especially solar, geothermal, and tidal power, show promise for reducing the carbon emissions of indoor VPF. Results show that renewably-powered VPF can reduce carbon emissions compared to field-based agriculture when considering the land-use change.
The drivers for DSS adoption have been researched, showing a pathway of compliance and design thinking to overcome the ‘problem of implementation’ and enable commercialisation. Further work is suggested to standardise VF equipment, collect benchmarking data, and characterise risks. This work will reduce risk and uncertainty and accelerate the sector’s emergence
Finnish Settler Colonialism in North America
Finnish Settler Colonialism in North America reinterprets Finnish experiences in North America by connecting them to the transnational processes of settler colonial conquest, far-settlement, elimination of natives, and capture of terrestrial spaces. Rather than merely exploring whether the idea of Finns as a different kind of immigrant is a myth, this book challenges it in many ways. It offers an analysis of the ways in which this myth manifests itself, why it has been upheld to this day, and most importantly how it contributes to settler colonialism in North America and beyond.
The authors in this volume apply multidisciplinary perspectives in revealing the various levels of Finnish involvement in settler colonialism. In their chapters, authors seek to understand the experiences and representations of Finns in North American spatial projects, in territorial expansion and integration, and visions of power. They do so by analyzing how Finns reinvented their identities and acted as settlers, participated in the production of settler colonial narratives, as well as benefitted and took advantage of settler colonial structures.
Finnish Settler Colonialism in North America aims to challenge traditional histories of Finnish migration, in which Finns have typically been viewed almost in isolation from the broader American context, not to mention colonialism. The book examines the diversity of roles, experiences, and narrations of and by Finns in the histories of North America by employing the settler colonial analytical framework
Consent and the Construction of the Volunteer: Institutional Settings of Experimental Research on Human Beings in Britain during the Cold War
This study challenges the primacy of consent in the history of human experimentation and argues that privileging the cultural frameworks adds nuance to our understanding of the construction of the volunteer in the period 1945 to 1970. Historians and bio-ethicists have argued that medical ethics codes have marked out the parameters of using people as subjects in medical scientific research and that the consent of the subjects was fundamental to their status as volunteers. However, the temporality of the creation of medical ethics codes means that they need to be understood within their historical context. That medical ethics codes arose from a specific historical context rather than a concerted and conscious determination to safeguard the well-being of subjects needs to be acknowledged. The British context of human experimentation is under-researched and there has been even less focus on the cultural frameworks within which experiments took place. This study demonstrates, through a close analysis of the Medical Research Council's Common Cold Research Unit (CCRU) and the government's military research facility, the Chemical Defence Experimental Establishment, Porton Down (Porton), that the `volunteer' in human experiments was a subjective entity whose identity was specific to the institution which recruited and made use of the subject. By examining representations of volunteers in the British press, the rhetoric of the government's collectivist agenda becomes evident and this fed into the institutional construction of the volunteer at the CCRU. In contrast, discussions between Porton scientists, staff members, and government officials demonstrate that the use of military personnel in secret chemical warfare experiments was far more complex. Conflicting interests of the military, the government and the scientific imperative affected how the military volunteer was perceived
