PQC_BD_2025
No full textThe rapid progress of quantum computing poses substantial risks to classical cryptographic mechanisms widely deployed in Big Data processing systems, whose distributed architectures, high computational intensity, and exposure to diverse attack vectors impose stringent requirements on long-term security and reliability. Accordingly, this study aims to develop a risk-oriented framework for assessing post-quantum cryptographic (PQC) algorithms in large-scale data environments. The proposed methodology integrates cryptographic reliability and computational efficiency within a unified multi-criteria decision-making model, incorporating formalised threat modelling, probabilistic analysis of resistance to classical and quantum attacks, robustness evaluation under high computational loads, and quantitative performance metrics, including latency, throughput, resource consumption, and scalability in distributed infrastructures. Based on this framework, a comparative analysis of representative classes of PQC algorithms is conducted in typical Big Data processing scenarios. The results indicate that different PQC families exhibit distinct security–performance trade-offs and that no single algorithm is universally optimal across all operational conditions. The study concludes that a risk-oriented, multi-criteria selection of post-quantum cryptographic mechanisms enhances the overall resilience and operational efficiency of secure Big Data systems, providing a practical foundation for their design, modernisation, and cybersecurity governance in the post-quantum era
Impact of physical and sensory disabilities in doctors on the level of trust among colleagues.
No full textIntroduction: Brazilian national policy prioritizes the inclusion of people with disabilities. Considering that there are medical professionals with disabilities and that there are CFM (Federal Council of Medicine) regulations that guarantee equality and inclusion of physicians with disabilities in medical practice, it is essential to analyze how interpersonal relationships are established in the workplace. In particular, it is necessary to verify the degree of trust of the medical team in relation to physicians with physical and sensory disabilities, since a lack of trust denotes prejudice.
Objective: To identify, categorize, and summarize the evidence on the impact of physical disability on physicians' trust and interpersonal relationships, including prejudice, discrimination, and mistreatment, and on the role of assistive technologies in promoting inclusion.
Methods: Scoping review in the Cochrane Library (via Wiley), EMBASE (via Elsevier), Medical Literature Analysis and Retrieval System Online (MEDLINE, via PubMed), and Lilacs databases. The organization of the research results will be based on four topics: trust, assistive technologies, prejudice, and barriers encountered in the practice of medicine. This scoping review will be developed following the methodological recommendations of the Joanna Briggs Institute Handbook, and the reporting recommendations according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses - extension for scoping reviews (PRISMA). The research question will be: ‘What evidence describes the impact of physicians' physical disabilities on the degree of trust among colleagues, and what factors (age, years of experience, type of disability, use of assistive technologies) influence this level of trust?’
Eligibility Criteria: Population - physicians (residents, specialists, and faculty). Concept - degree of professional trust and interpersonal relationships (including manifestations of prejudice, discrimination, mistreatment), as well as influencing factors (age, years of experience, type of disability) and the use/impact of assistive technologies. Context - health services or systems such as hospitals, clinics, community services, and academic settings. In summary, the scoping review will include studies that meet the following criteria: primary studies, with a qualitative, quantitative, or mixed approach; studies that address physicians with physical and/or sensory disabilities, or that discuss disability in the practice of medicine; studies that analyze interpersonal relationships, level of trust, prejudice, discrimination, stigma, or professional barriers in the context of medicine; studies that address the use of assistive technologies related to medical practice or professional inclusion; publications available in full text; studies published without restriction of period or language; studies conducted in healthcare service settings, academic institutions, or medical practice environments.
Expected Results: The main expected outcome of this project is to highlight the impact of physician disabilities on the level of trust among colleagues in their work in a southern Brazilian state, as well as to foster discussion on this topic among academics, physicians, and managers, so that they can become multipliers of a culture of inclusion within healthcare institutions. Secondary results that this study seeks to present include: the influence of the participating physician's age on the level of trust attributed; the influence of professional experience on the level of trust; the influence of the type of physical or sensory disability on the perception of trust; and the influence of the use of assistive technologies on the level of trust attributed
Pedometer integrated into a digital application designed for healthcare professionals to facilitate motivational interventions (POD-iSanté project): Acceptability study protocol
No full textThis project evaluates the acceptability of POD‑iSanté, a tool combining a pedometer with a digital application to support motivational interventions by healthcare professionals. A sequential explanatory mixed‑methods design will be used, beginning with an online questionnaire based on Sekhon’s acceptability framework, followed by semi‑structured interviews. Qualitative analysis will be guided by Meleis’ Transition Theory to better understand factors influencing implementation in clinical practice. Findings will include descriptive statistics for acceptability dimensions and key qualitative themes
Negotiating between practicum partnership spaces in ITE: experiences from Scotland
No full textThe ‘practicum’ is a critical component of Initial Teacher Education (ITE), where student teachers develop their professional competence and identity in schools alongside experienced educators. This paper presents findings from a survey of Scottish ITE partnership actors, involving three universities and six local authorities, highlighting common elements that can hinder the effectiveness of placement ecosystems. The partnership is an important enquiry context as international systems question how to ensure high quality ITE experiences for all novice teachers through different governance models. The success of the practicum in fostering meaningful early professional development depends on how expectations are communicated, and how key practices are defined and enacted at macro- (national agency), meso- (university and school) and micro- (individual) levels. Student teachers are not located simply ‘at school’ or ‘at university’ but in constructed and negotiated spaces in between, shedding new light on professional relationships within the field of teacher education

No full textThis registration provides a curated dataset of security vulnerabilities affecting smart home IoT technologies, including smart cameras, smart locks, motion and presence sensors, and video-related communication protocols.
The dataset integrates CVE and CWE information, maps vulnerabilities to the OWASP IoT Top 10 (2018), and applies an ODC-based classification adapted to the IoT security domain. The purpose of this registration is to freeze the current version of the dataset for citation, reproducibility, and long-term preservation
Football club communications and identity leadership: A framework analysis
No full textFootball club engagement in identity leadership has been found to positively contribute to fan-club relationships and spectator feelings of safety at matches. However, limited research has explored how clubs show identity leadership in their communication with fans. To address this, we conducted a Framework Analysis of Facebook posts and emails to supporters from two football clubs (Hibernian FC and Liverpool FC) across three weeks of the football season (N = 780). Our analysis identified that football club communications often use content from players and managers to define what it means to be a group member (i.e., a ‘Red’ or a ‘Hibee’) (entrepreneurship), to acknowledge and demonstrate delivering on the opinions and expectations of supporters (advancement), and to promote the importance of supporters to the club (impresarioship). We conclude that football clubs illustrate identity leadership via official communication channels, but that the content of these messages predominantly come from players and managers (i.e., those who can be considered prototypical group members). These insights are key for the development of club communication guidance designed to promote positive fan-club relationships
