Divide-and-conquer the NAS puzzle in resource-constrained federated learning systems.

Federated Learning (FL) is a privacy-preserving distributed machine learning approach geared towards applications in edge devices. However, the problem of designing custom neural architectures in federated environments is not tackled from the perspective of overall system efficiency. In this paper, we propose DC-NAS-a divide-and-conquer approach that performs supernet-based Neural Architecture Search (NAS) in a federated system by systematically sampling the search space. We propose a novel diversified sampling strategy that balances exploration and exploitation of the search space by initially maximizing the distance between the samples and progressively shrinking this distance as the training progresses. We then perform channel pruning to reduce the training complexity at the devices further. We show that our approach outperforms several sampling strategies including Hadamard sampling, where the samples are maximally separated. We evaluate our method on the CIFAR10, CIFAR100, EMNIST, and TinyImagenet benchmarks and show a comprehensive analysis of different aspects of federated learning such as scalability, and non-IID data. DC-NAS achieves near iso-accuracy as compared to full-scale federated NAS with 50% fewer resources.

Factors Influencing the Sharing of Personal Health Data Based on the Integrated Theory of Privacy Calculus and Theory of Planned Behaviors Framework: Results of a Cross-Sectional Study of Chinese Patients in the Yangtze River Delta.

BACKGROUND: The health care system in China is fragmented, and the distribution of high-quality resources remains uneven and irrational. Information sharing is essential to the development of an integrated health care system and maximizing its benefits. Nevertheless, data sharing raises concerns regarding the privacy and confidentiality of personal health information, which affect the willingness of patients to share information. OBJECTIVE: This study aims to investigate patients' willingness to share personal health data at different levels of maternal and child specialized hospitals in China, to propose and test a conceptual model to identify key influencing factors, and to provide countermeasures and suggestions to improve the level of data sharing. METHODS: A research framework based on the Theory of Privacy Calculus and the Theory of Planned Behavior was developed and empirically tested through a cross-sectional field survey from September 2022 to October 2022 in the Yangtze River Delta region, China. A 33-item measurement instrument was developed. Descriptive statistics, chi-square tests, and logistic regression analyses were conducted to characterize the willingness of sharing personal health data and differences by sociodemographic factors. Structural equation modeling was used to assess the reliability and validity of the measurement as well as to test the research hypotheses. The STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) checklist for cross-sectional studies was applied for reporting results. RESULTS: The empirical framework had a good fit with the chi-square/degree of freedom (χ2/df)=2.637, root-mean-square residual=0.032, root-mean-square error of approximation=0.048, goodness-of-fit index=0.950, and normed fit index=0.955. A total of 2060 completed questionnaires were received (response rate: 2060/2400, 85.83%). Moral motive (ß=.803, P<.001), perceived benefit (ß=.123, P=.04), and perceived effectiveness of government regulation (ß=.110, P=.001) had a significantly positive association with sharing willingness, while perceived risk (ß=-.143, P<.001) had a significant negative impact, with moral motive having the greatest impact. The estimated model explained 90.5% of the variance in sharing willingness. CONCLUSIONS: This study contributes to the literature on personal health data sharing by integrating the Theory of Privacy Calculus and the Theory of Planned Behavior. Most Chinese patients are willing to share their personal health data, which is primarily motivated by moral concerns to improve public health and assist in the diagnosis and treatment of illnesses. Patients with no prior experience with personal information disclosure and those who have tertiary hospital visits were more likely to share their health data. Practical guidelines are provided to health policy makers and health care practitioners to encourage patients to share their personal health information.

Perspectives of patients with colorectal cancer liver metastases on e-consultation in transmural care: a qualitative study : Is privacy really an issue?

BACKGROUND: Comprehensive cancer networks have been established to deliver high-quality care for patients with cancer. Logistic challenges are faced, when patients need to be referred for specialized treatments. Despite strengthened privacy legislations, digital platforms are increasingly used to consult specialists from dedicated liver centers or refer patients with colorectal cancer liver metastases (CRLM) for local treatment strategies. This qualitative study aimed to explore the perspectives of patients with CRLM regarding e-consultation of transmural specialists. METHODS: A focus group study was conducted. Patients referred from regional hospitals to an academic liver center for treatment of CRLM were asked to participate. Focus group discussions were audio-recorded and transcribed verbatim. A thematic content analysis of data was conducted, comprising open, axial, and selective coding of the transcripts. The consolidated criteria for reporting qualitative research (COREQ) were used. RESULTS: Two focus groups were held, involving 11 patients and 8 relatives. Three major themes were identified with regard to e-consultation in transmural care: 'data management', 'expertise', and 'information and coordination'. Confidence in the expertise of physicians appeared most important during the course of treatment, as patients experienced uncertainty after diagnosis of cancer. Despite the privacy risks, use of digital communication platforms to contact experts in the field were strongly endorsed to improve eligibility for potentially curative treatment. Moreover, e-consultation of specialists may reduce waiting times, due to effective coordination of care. CONCLUSION: Initiatives to improve medical data transfer between care providers were encouraged to achieve effective coordination of oncological care. The potential hazard of privacy violation associated with digital data exchange is accepted by patients and their relatives, provided that use of digital data improves patient's own health care, research or education.

How physical home workspace characteristics affect mental health: A systematic scoping review.

BACKGROUND: During the 1990s, voluntary teleworking became more grounded, because of expected advantages as increased productivity and comfort. However, COVID-19 obliged employees to work from home (WFH), even in unsuitable houses, which might have reduced their mental health. A holistic overview of methods and measures of the physical home-workspace characteristics and mental health is currently lacking. Insights in the potential influence of the physical home-workspace on mental health are also not yet holistically examined. OBJECTIVE: The aim of this study is to provide insights in previously studied relationships between the physical home-workspace and mental health and to identify measures for both using a systematic scoping review. METHODS: This study used the PRISMA method to systematically review existing literature. RESULTS: Most studies focussed on noise, acoustics, and privacy, in relation to productivity, concentration, and sleep quality. Only a few studies used objective measures for physical home-workspace characteristics. CONCLUSION: The list of relevant measures can be used by academics to examine relationships between the home-workspace and mental health further. Workplace managers can use it to help employees in optimizing their home-workspace.

Mapping Evidence Regarding Decision-Making on Contraceptive Use among Adolescents in Sub-Saharan Africa: A Scoping Review.

This scoping review mapped and synthesised existing evidence on the influence of individual, parental, peer, and societal-related factors on adolescents' decisions to use contraception in sub-Saharan Africa (SSA). Peer-reviewed and review articles published before May 2022, targeting adolescents aged 10-19 years were searched in PubMed, MEDLINE with Full Text via EBSCOhost, PsychINFO via EBSCOhost, CINAHL with Full Text via EBSCOhost, Google Scholar, Science Direct, and Scopus databases. Seven studies were included and analysed using thematic analysis based on the social-ecological model (SEM) and reported using the preferred reporting items for systematic reviews and meta-analyses (PRISMA). Individual (fear of side effects, fear of infertility), parental (parental disappointment and disapproval), peer (social stigma), partner (association with promiscuity and multiple sexual partners), societal and community (contraceptive use disapproval and stigma), and institutional and environmental factors (lack of privacy and confidentiality) influence contraceptive decisions among adolescents. These also include a lack of accurate information, social exclusion, negative health provider attitudes, and a lack of infrastructure that provides privacy and safe spaces. Identifying and addressing core issues within the context of local cultural practices that restrict contraceptive use is important. Holistic, inclusive approaches that promote the well-being of adolescents must be utilised to provide a conducive environment that ensures privacy, confidentiality, safety, and easy access to contraceptive services.

Percepção sobre o cuidado à perda gestacional: estudo qualitativo com casais brasileiros / Perceptions on pregnancy loss care: a qualitative study with brazilian couples / Percepción sobre la atención a la pérdida del embarazo: estudio cualitativo con parejas brasileñas

Este artigo analisou a percepção e os sentimentos de casais sobre o atendimento recebido nos serviços de saúde acessados em função de perda gestacional (óbito fetal ante e intraparto). O convite para a pesquisa foi divulgado em mídias sociais (Instagram e Facebook). Dos 66 casais que contataram a equipe, 12 participaram do estudo, cuja coleta de dados ocorreu em 2018. Os casais responderam conjuntamente a uma ficha de dados sociodemográficos e uma entrevista semiestruturada, realizada presencialmente (n=4) ou por videochamada (n=8). Os dados foram gravados em áudio e posteriormente transcritos. A Análise Temática indutiva das entrevistas identificou cinco temas: sentimento de impotência, iatrogenia vivida nos serviços, falta de cuidado em saúde mental, não reconhecimento da perda como evento com consequências emocionais negativas, e características do bom atendimento. Os achados demonstraram situações de violência, comunicação deficitária, desvalorização das perdas precoces, falta de suporte para contato com o bebê falecido e rotinas pouco humanizadas, especialmente durante a internação após a perda. Para aprimorar a assistência às famílias enlutadas, sugere-se qualificação profissional, ampliação da visibilidade do tema entre diferentes atores e reorganização dos serviços, considerando uma diretriz clínica para atenção ao luto perinatal, com destaque para o fortalecimento da inserção de equipes de saúde mental no contexto hospitalar.(AU)

This study analyzed couples' perceptions and feelings about pregnancy loss care (ante and intrapartum fetal death). A research invitation was published on social media (Instagram and Facebook) and data collection took place in 2018. Of the 66 couples who contacted the research team, 12 participated in the study by filling a sociodemographic questionnaire and answering a semi-structured interview in person (n=04) or by video call (n=08). All interviews were audio recorded, transcribed, and examined by Inductive Thematic Analysis, which identified five themes: feelings of impotence, iatrogenic experiences in health services, lack of mental health care, not recognizing pregnancy loss as an emotionally overwhelming event, and aspects of good healthcare. Analysis showed experiences of violence, poor communication, devaluation of early losses, lack of support for contact with the deceased baby, and dehumanizing routines, especially during hospitalization after loss. Professional qualification, extended pregnancy loss visibility among different stakeholders, and reorganization of health services are needed to improve the care offered to grieving families, considering a clinical guideline for perinatal grief care with emphasis on strengthening the insertion of mental health teams in the hospital context.(AU)

A invenção de um setting on-line para atendimento psicológico remoto / The invention of an online environment for remote psychological care / La invención de un entorno en línea para la atención psicológica remota

Com o advento da covid-19, foi declarado estado de emergência de saúde pública e decretadas medidas de isolamento e distanciamento social para conter a propagação da doença. O Conselho Federal de Psicologia, considerando a importância do acolhimento seguro durante a pandemia, publicou a Resolução CFP nº 4/2020, permitindo que serviços psicológicos aconteçam de maneira remota. O presente estudo visa, através do Método da Cartografia, apresentar a construção de um setting on-line para intervenções grupais e os desafios na oferta de acolhimento e atendimento remoto. Foram ofertados grupos terapêuticos, por meio da plataforma Google Meet, para estudantes da Universidade Federal Rural do Rio de Janeiro. Um diário de bordo foi produzido para acompanhar as forças que atravessavam e constituíam o território e a experiência grupal remota. Compreendemos que o território-espaço-grupal-on-line era composto pelo espaço virtual em que nos reuníamos, pelos espaços individuais de cada integrante e pelas forças que os atravessavam. Observamos que nem sempre os participantes dispunham de um lugar privado, mas estiveram presentes no encontro com câmeras e áudios abertos e/ou fechados e/ou através do chat da videochamada. A participação no grupo funcionou como alternativa no momento de distanciamento social, sendo uma possibilidade para o atendimento psicológico em situações de dificuldade de encontros presenciais; entretanto, se mostrou dificultada em diversos momentos, pela falta de equipamentos adequados e instabilidade na internet, fatores que interferiram nas reuniões e impactaram na possibilidade de falar e escutar o que era desejado.(AU)

With the advent of COVID-19, a state of public health was declared, and measures of isolation and social distance to contain the spread of the disease was decreed. The Federal Council of Psychology, considering the importance of safe reception during the pandemic, published CFP Resolution No. 4/2020, allowing psychological services to happen remotely. This study narrates, via the Cartography Method, the experience of inventing an Online Setting for group reception. Therapeutic groups were offered, via Google Meet Platform, to students at the Federal Rural University of Rio de Janeiro. A logbook was produced to accompany the forces that crossed and constituted the territory and the remote group experience. We understand that the territoryspace-group-online was composed by the virtual-space that we gathered, by the individualspaces of each member and by the forces that crossed them. We observed that the participants did not always have a private place, but they were present at the meeting with open and/or closed cameras and audio and/or through the video call chat. Participation in the group worked as an alternative at the time of social distancing, being a possibility for psychological care in situations of difficulty in face-to-face meetings, however, it proved to be difficult at various times, due to the lack of adequate equipment and instability on the internet, factors that interfered in meetings and impacted the possibility of speaking and listening to what was desired.(AU)

A coisa em psicanálise e o objeto no lísis de Platão / The thing in psychoanalysis and object in Plato's lysis / La cosa en psicoanálisis y el objeto en lisis de Platón

Este artigo propõe o estudo sobre o conceito de outro como semelhante e como objeto. Partindo de textos que interpelam a alteridade na psicanálise e remetendo aos temas do complexo semelhante, da satisfação, da perda, do luto, da negativa, da repetição; avalia o conceito de outro articulando textos de diversos autores. A partir da psicanálise freudiana, estuda o das Ding e a negação, discriminando com estes termos um objeto estruturante na origem do psiquismo. Aborda textos técnicos da psicanálise para delimitar o tema da repetição. Também a recordação e a repetição são vinculadas ao objeto e estudadas na perspectiva da filosofia moderna. São retomados temas do diálogo platônicos para definir o lugar do erótico e da amizade. No fim do presente artigo, propomos o termo clássico grego Oikos com valor equivalente ao da Coisa freudiana e como esta aparece em escritos psicanalíticos.(AU)

This article studies the concept of other as similar and object. It is based on texts that question the alterity in psychoanalysis and refers to the themes of otherness complex, loss, grief, negative, repetition, and evaluates the concept of other, using articles of diverse authors. Based on Freudian psychoanalysis, it studies the Thing and the denial and discriminates a structuring object in the origin of psychism. It approaches technical texts of psychoanalysis to delimitate the theme of repetition. The recordation and repetition are also linked to the object and studied from the perspective of modern philosophy. Themes of the platonic dialogues are resumed to define the place of the erotic and the friendship. In the end of the article, we propose the greek classic term Oikos, with equal value to the Freudian Thing, as this one appears in psychoanalytic writings.(AU)

Privacy and Trust in pHealth - Past, Present and Future.

From beginning to today, pHealth has been a data driven service that collects and uses personal health information (PHI) for personal health services and personalized healthcare. As a result, pHealth services use intensively ICT technology, sensors, computers and mathematical algorithms. In past, pHealth applications were focused to certain health or sickness related problem, but in today they use mobile devices, wireless networks, Web-technology and Cloud platforms. In future, pHealth uses information systems that are highly distributed, dynamic, increasingly autonomous, multi-stakeholder data driven eco-system having ability to monitor anywhere person's regular life, movements and health related behaviours. Because privacy and trust are pre-requirements for successful pHealth, this development raises huge privacy and trust challenges to be solved. Researchers have shown that current privacy approaches and solutions used in pHealth do not offer acceptable level of privacy, and trust is only an illusion. This indicates, that today's privacy models and technology shall not be moved to the future pHealth. The authors have analysed interesting new privacy and trust ideas published in journals, and found that they seem to be effective but offer only a partial solution. To solve this weakness, the authors used a holistic system view to aspects impacting privacy and trust in pHealth, and created a template that can be used in planning and development future pHealth services. The authors also propose a tentative solution for future trustworthy pHealth. It combines privacy as personal property and trust as legal binding fiducial duty approaches, and uses a Blockchain-based smart contract solution to store person's privacy and trust requirements and service providers' promises.

Multi-Source Decentralized Transfer for Privacy-Preserving BCIs.

Transfer learning, which utilizes labeled source domains to facilitate the learning in a target model, is effective in alleviating high intra- and inter-subject variations in electroencephalogram (EEG) based brain-computer interfaces (BCIs). Existing transfer learning approaches usually use the source subjects' EEG data directly, leading to privacy concerns. This paper considers a decentralized privacy-preserving transfer learning scenario: there are multiple source subjects, whose data and computations are kept local, and only the parameters or predictions of their pre-trained models can be accessed for privacy-protection; then, how to perform effective cross-subject transfer for a new subject with unlabeled EEG trials? We propose an offline unsupervised multi-source decentralized transfer (MSDT) approach, which first generates a pre-trained model from each source subject, and then performs decentralized transfer using the source model parameters (in gray-box settings) or predictions (in black-box settings). Experiments on two datasets from two BCI paradigms, motor imagery and affective BCI, demonstrated that MSDT outperformed several existing approaches, which do not consider privacy-protection at all. In other words, MSDT achieved both high privacy-protection and better classification performance.

Implementation of a Sense of Home in High-Density Multicultural Singapore Nursing Homes: Challenges and Opportunities.

Many studies have introduced principles for creating a sense of home in nursing homes, yet they mostly feature cases from low-density developments in Western countries. This raises a question about how those principles are interpreted and implemented in other cultural contexts, especially in high-density, multicultural environments such as Singapore. This paper examines how a sense of home is implemented in Singapore nursing homes, with a specific focus on the role of the built environment. Participant observations were conducted in five nursing homes in Singapore comprising various architectural design typologies, with the focus on the residents' everyday interactions with their built environment. The study identified the extent of the presence of a sense of home in Singapore's nursing homes and the prevalence of an institutional care model. More specifically, the study explicates Singapore nursing home residents' management of privacy and personalization in shared spaces, illuminates the need for holistic implementation of homelike environments integrated with building designs and care programs and reiterates the pivotal role of social relationships in fostering a sense of home for the residents in the nursing homes.

Privacy-Preserving Domain Adaptation for Motor Imagery-Based Brain-Computer Interfaces.

OBJECTIVE: Electroencephalogram (EEG) is one of the most widely used signals in motor imagery (MI) based brain-computer interfaces (BCIs). Domain adaptation has been frequently used to improve the accuracy of EEG-based BCIs for a new user (target domain), by making use of labeled data from a previous user (source domain). However, this raises privacy concerns, as EEG contains sensitive health and mental information. It is very important to perform privacy-preserving domain adaptation, which simultaneously improves the classification accuracy for a new user and protects the privacy of a previous user. METHODS: We propose augmentation-based source-free adaptation (ASFA), which consists of two parts: 1) source model training, where a novel data augmentation approach is proposed for MI EEG signals to improve the cross-subject generalization performance of the source model; and, 2) target model training, which simultaneously considers uncertainty reduction for domain adaptation and consistency regularization for robustness. ASFA only needs access to the source model parameters, instead of the raw EEG data, thus protecting the privacy of the source domain. We further extend ASFA to a stricter privacy-preserving scenario, where the source model's parameters are also inaccessible. RESULTS: Experimental results on four MI datasets demonstrated that ASFA outperformed 15 classical and state-of-the-art MI classification approaches. SIGNIFICANCE: This is the first work on completely source-free domain adaptation for EEG-based BCIs. Our proposed ASFA achieves high classification accuracy and strong privacy protection simultaneously, important for the commercial applications of EEG-based BCIs.

Data privacy concerns and use of telehealth in the aged care context: An integrative review and research agenda.

OBJECTIVE: Effective use of telehealth offers substantial benefits to older persons and aged care providers. However, data privacy concerns challenge the effective use of telehealth and subsequent business value. Through developing a theoretical model, we explain how privacy concerns can influence the adoption ad use of telehealth in this complex context. METHOD: An integrative review of empirical investigations was conducted by linking privacy concerns, telehealth use, and aged care. We searched three major databases (PubMed, Web of Science, and Scopus) for articles published until December 2020. Articles were analyzed and presented using an integrative theoretical model that we labeled CPCPO (Context-Privacy Concerns-Practice-Outcomes). RESULTS: Our review revealed that privacy concerns are a contextual concept, i.e., different contexts (users, telehealth systems, aged care services, data) produce different privacy concerns. We found that privacy concerns were more voiced in home telecare and were associated with the degree of telemonitoring and surveillance. Contextual privacy concerns were related to video recording, behavioral data (e.g., sleep patterns and eating behavior), location data, and future use of data. These concerns can influence the adoption and use of telehealth. However, privacy protection practices (e.g., informed consent) can help in reducing the concerns and improving the acceptance of telehealth for older persons. CONCLUSION: CPCPO offers contextual explanations of telehealth privacy concerns and systems use. For improving telehealth acceptance, privacy concerns of data processing (e.g., recording, collection, storage, and secondary use) must be addressed by performing data protection practices. Based on the review results, we suggest avenues for future research.

Digital Contact Tracing Apps for COVID-19: Development of a Citizen-Centered Evaluation Framework.

BACKGROUND: The silent transmission of COVID-19 has led to an exponential growth of fatal infections. With over 4 million deaths worldwide, the need to control and stem transmission has never been more critical. New COVID-19 vaccines offer hope. However, administration timelines, long-term protection, and effectiveness against potential variants are still unknown. In this context, contact tracing and digital contact tracing apps (CTAs) continue to offer a mechanism to help contain transmission, keep people safe, and help kickstart economies. However, CTAs must address a wide range of often conflicting concerns, which make their development/evolution complex. For example, the app must preserve citizens' privacy while gleaning their close contacts and as much epidemiological information as possible. OBJECTIVE: In this study, we derived a compare-and-contrast evaluative framework for CTAs that integrates and expands upon existing works in this domain, with a particular focus on citizen adoption; we call this framework the Citizen-Focused Compare-and-Contrast Evaluation Framework (C3EF) for CTAs. METHODS: The framework was derived using an iterative approach. First, we reviewed the literature on CTAs and mobile health app evaluations, from which we derived a preliminary set of attributes and organizing pillars. These attributes and the probing questions that we formulated were iteratively validated, augmented, and refined by applying the provisional framework against a selection of CTAs. Each framework pillar was then subjected to internal cross-team scrutiny, where domain experts cross-checked sufficiency, relevancy, specificity, and nonredundancy of the attributes, and their organization in pillars. The consolidated framework was further validated on the selected CTAs to create a finalized version of C3EF for CTAs, which we offer in this paper. RESULTS: The final framework presents seven pillars exploring issues related to CTA design, adoption, and use: (General) Characteristics, Usability, Data Protection, Effectiveness, Transparency, Technical Performance, and Citizen Autonomy. The pillars encompass attributes, subattributes, and a set of illustrative questions (with associated example answers) to support app design, evaluation, and evolution. An online version of the framework has been made available to developers, health authorities, and others interested in assessing CTAs. CONCLUSIONS: Our CTA framework provides a holistic compare-and-contrast tool that supports the work of decision-makers in the development and evolution of CTAs for citizens. This framework supports reflection on design decisions to better understand and optimize the design compromises in play when evolving current CTAs for increased public adoption. We intend this framework to serve as a foundation for other researchers to build on and extend as the technology matures and new CTAs become available.

Ethical, Legal and Social Issues of Digital Phenotyping as a Future Solution for Present-Day Challenges: A Scoping Review.

Digital phenotyping represents an avenue of consideration in patients' self-management. This scoping review aims to explore the trends in the body of literature on ethical, legal, and social challenges relevant to the implementation of digital phenotyping technologies in healthcare. The study followed the PRISMA-ScR methodology (Tricco et al. in Ann Int Med 169(7):467-473, 2018. https://doi.org/10.7326/M18-0850 ). The review systematically identified relevant literature, characterised the discussed technology, explored its impacts and the proposed solutions to identified challenges. Overall, the literature, perhaps unsurprisingly, concentrates on technical rather than ethical, legal, and social perspectives, which limits understanding of the more complex cultural and social factors in which digital phenotyping technologies are embedded. ELS issues mostly concern privacy, security, consent, lack of regulation, and issues of adoptability, and seldom expand to more complex ethical issues. Trust was chosen as an umbrella theme of a continuum of major ELS and technical issues. Sustained critical analysis of digital phenotyping showed to be sparse and geographically exclusive. There is a continuum and overlap between ELS issues, suggesting the need for a holistic, interdisciplinary approach to each of the challenges posed by the various technologies of digital phenotyping.

PeTroShare: Blockchain-Managed, Logistics-Aware, Privacy-Friendly, Comparative, and Efficient Petroleum Transportation.

Crude oil is one of the critically needed resources. It is the main pillar supporting almost everything we rely on in daily life. Unfortunately, due to many factors, crude oil costs too much. Transportation is one of the critical factors that affect such costs. Due to many environmental risks attached to the transportation process, many countries added very high tariffs to cover any hazards during the transportation, loading, and unloading process. Logistics concerns and political conflicts are the other key factors that can massively impact the transportation cost. This paper presents an Industry 4.0-compliant PeTroShare (PTS), a blockchain-powered trustworthy, logistics-friendly, and cost-efficient crude oil trading platform. PTS is a novel ride-sharing platform that enables an anonymous exchange of crude oil between oil producers and customers, focusing mainly on the product quality, not the source of origin. In our scenario, floating crude oil tankers will hold the cargo to an intermediate position in the open ocean. PTS will match the product availability based on the location and the needed quality of the customer requests. Consequently, the time and distance travelled are minimized. Our simulation results show that enabling the anonymous sharing of crude oil products can significantly enhance system efficiency and cost-effectiveness.

Privacy Protection and Secondary Use of Health Data: Strategies and Methods.

Health big data has already been the most important big data for its serious privacy disclosure concerns and huge potential value of secondary use. Measurements must be taken to balance and compromise both the two serious challenges. One holistic solution or strategy is regarded as the preferred direction, by which the risk of reidentification from records should be kept as low as possible and data be shared with the principle of minimum necessary. In this article, we present a comprehensive review about privacy protection of health data from four aspects: health data, related regulations, three strategies for data sharing, and three types of methods with progressive levels. Finally, we summarize this review and identify future research directions.

Midwife and nurse students' perceptions of body privacy and self esteem: the case of Turkey / Percepciones de los estudiantes de obstetricia y enfermería sobre la intimidad corporal y la autoestima: el caso de Turquía / Percepções dos estudantes de obstetrícia e de enfermagem sobre a intimidade corporal e a autoestima: o caso da Turquia

Abstract The article reports the results of a study conducted to examine midwifery and nursing students' perceptions of body intimacy and the factors affecting their perceptions. This was a cross-sectional study, with 389 midwifery and nursing students at a public university volunteering to participate in the study. Data were collected using a "Personal Information Form", the "Body Confidentiality Scale for Obstetrics and Gynecology" and the "Rosenberg Self-Esteem Scale". The participants had a mean age of 20.89 ± 1.86 years. The mean score they gave to the question whether they paid attention to privacy was 8.21 ±1.88. The mean Rosenberg self-esteem score was 29.44 ± 4.83 (minimum = 10, maximum = 40). The mean overall privacy score was 36.10 ± 6.84 (min = 9, max = 45), rights and privacy was 20.80 ± 3.71 (min = 5, max = 25), ethics and privacy was 20.45 ± 3.67 (min = 5, max = 25), and clinical privacy was 75.22 ± 12.33 (min = 18, max = 90). According to the results, obstetrics and nursing students, who would later intervene in women's health, had higher than average self-esteem and perception of privacy. Nevertheless, the establishment of the concept of "privacy" is an issue that should be addressed and reinforced in the training of obstetrics and nursing students who will provide services in such a sensitive field as gynecology and obstetrics.

Resumen El artículo informa de los resultados de un estudio llevado a cabo para examinar las percepciones de la intimidad corporal de los estudiantes de obstetricia y enfermería y los factores que afectan a sus percepciones. Se trató de un estudio transversal, con 389 estudiantes de obstetricia y enfermería de una universidad pública que se ofrecieron a participar en el estudio. Los datos se recogieron mediante un "Formulario de información personal", la "Escala de confidencialidad corporal para ginecología y obstetricia" y la "Escala de autoestima de Rosenberg". Los participantes tenían una edad media de 20,89 ± 1,86 años. La puntuación media que dieron a la cuestión de si prestaban atención a la intimidad fue de 8,21 ±1,88. La puntuación media de la autoestima de Rosenberg fue de 29,44 ± 4,83 (mínimo = 10, máximo = 40). La puntuación media de privacidad general fue de 36,10 ± 6,84 (mín = 9, máx = 45), la de derechos y privacidad fue de 20,80 ± 3,71 (mín = 5, máx = 25), la de ética y privacidad fue de 20,45 ± 3,67 (mín = 5, máx = 25), y la de privacidad clínica fue de 75,22 ± 12,33 (mín = 18, máx = 90). De acuerdo con los resultados, los estudiantes de obstetricia y enfermería, que intervendrían luego en la salud de las mujeres, tenían una autoestima y una percepción de la privacidad superiores a la media. No obstante, el establecimiento del concepto de "privacidad" es una cuestión que debería abordarse y reforzarse en la formación de los estudiantes de obstetricia y enfermería que van a prestar servicios en un ámbito tan delicado como la ginecología y la obstetricia.

Resumo O artigo informa sobre os resultados de um estudo realizado para examinar as percepções da intimidade corporal dos estudantes de obstetrícia e de enfermagem e os fatores que afetam suas percepções. Trata-se de um estudo transversal, com 389 estudantes de obstetrícia e de enfermagem de uma universidade pública que se ofereceram para participar no estudo. Os dados foram coletados mediante um "Formulário de informação pessoal", a "Escala de confidencialidade corporal para ginecologia e obstetrícia" e a "Escala de autoestima de Rosenberg". Os participantes tinham uma idade média de 20,89 ± 1,86 anos. A pontuação média que deram à questão de se prestavam atenção à intimidade foi de 8,21 ±1,88. A pontuação média de autoestima de Rosenberg foi de 29,44 ± 4,83 (mínimo = 10, máximo = 40). A pontuação média de privacidade geral foi de 36,10 ± 6,84 (min = 9, max = 45), a de direitos e privacidade foi de 20,80 ± 3,71 (min = 5, max = 25), a de ética e privacidade foi de 20,45 ± 3,67 (min = 5, max = 25) e a de privacidade clínica foi de 75,22 ± 12,33 (min = 18, max = 90).

Não obstante, o estabelecimento do conceito de "privacidade" é uma questão que deveria ser abordada e reforçada na formação dos estudantes de obstetrícia e de enfermagem que irão prestar serviços em um âmbito tão delicado como a ginecologia e a obstetrícia.

Automated Cyber and Privacy Risk Management Toolkit.

Addressing cyber and privacy risks has never been more critical for organisations. While a number of risk assessment methodologies and software tools are available, it is most often the case that one must, at least, integrate them into a holistic approach that combines several appropriate risk sources as input to risk mitigation tools. In addition, cyber risk assessment primarily investigates cyber risks as the consequence of vulnerabilities and threats that threaten assets of the investigated infrastructure. In fact, cyber risk assessment is decoupled from privacy impact assessment, which aims to detect privacy-specific threats and assess the degree of compliance with data protection legislation. Furthermore, a Privacy Impact Assessment (PIA) is conducted in a proactive manner during the design phase of a system, combining processing activities and their inter-dependencies with assets, vulnerabilities, real-time threats and Personally Identifiable Information (PII) that may occur during the dynamic life-cycle of systems. In this paper, we propose a cyber and privacy risk management toolkit, called AMBIENT (Automated Cyber and Privacy Risk Management Toolkit) that addresses the above challenges by implementing and integrating three distinct software tools. AMBIENT not only assesses cyber and privacy risks in a thorough and automated manner but it also offers decision-support capabilities, to recommend optimal safeguards using the well-known repository of the Center for Internet Security (CIS) Controls. To the best of our knowledge, AMBIENT is the first toolkit in the academic literature that brings together the aforementioned capabilities. To demonstrate its use, we have created a case scenario based on information about cyber attacks we have received from a healthcare organisation, as a reference sector that faces critical cyber and privacy threats.

Privacy, Early Colostrum, and Gestational Age are Associated with Exclusive Breastfeeding in Preterm and Sick Term Infants.

Our study was designed to assess the rates of exclusive breastfeeding (defined as direct breastfeeding) and the use of mother's own milk (MOM) in preterm infants and sick term infants at discharge and to identify potential influencing factors such as gestational age, early colostrum, and privacy. The study was conducted at a German level III neonatal department. All preterm and sick term infants admitted to the neonatal intensive care unit, the pediatric intensive care unit, the intermediate care unit, and the low care ward were included in the study. Infants were recruited between March and October 2015 (phase 1) and April to July 2016 (phase 2). Due to an emergency evacuation, privacy was limited during the first phase. Breastfeeding and the use of MOM were assessed daily using a self-designed score. In total, 482 infants of 452 mothers were included. More than 90% initiated breastfeeding and one-third were exclusively breastfed at discharge. Extremely immature infants and late preterm infants were less likely to be exclusively breastfed at discharge. Privacy (p<0.001) and early colostrum (p=0.002) significantly increased exclusive breastfeeding. Conclusion Extremely immature and late preterm infants were least likely to be exclusively breastfed at discharge and need special support. Interventions such as privacy and early colostrum should be promoted to increase breastfeeding.
