In: Acta Materialia. - : Elsevier. - 1359-6454 .- 1873-2453. ; 250

Journal article (peer-reviewed)abstract
- Ion-irradiation-induced changes in structure, elastic properties, and thermal stability of metastable c-(Ti,Al)N thin films synthesized by high-power pulsed magnetron sputtering (HPPMS) and cathodic arc deposition (CAD) are systematically investigated by experiments and density functional theory (DFT) simulations. While films deposited by HPPMS show a random orientation at ion kinetic energies (Ek)>105 eV, an evolution towards (111) orientation is observed in CAD films for Ek>144 eV. The measured ion energy flux at the growing film surface is 3.3 times larger for CAD compared to HPPMS. Hence, it is inferred that formation of the strong (111) texture in CAD films is caused by the ion flux-and ion energy-induced strain energy minimization in defective c-(Ti,Al)N. The ion energy-dependent elastic modulus can be rationalized by considering the ion energy-and orientation -dependent formation of point defects from DFT predictions: The balancing effects of bombardment-induced Frenkel defects formation and the concurrent evolution of compressive intrinsic stress result in the apparent independence of the elastic modulus from Ek for HPPMS films without preferential orientation. However, an ion energy-dependent elastic modulus reduction of similar to 18% for the CAD films can be understood by considering the 34% higher Frenkel pair concentration formed at Ek=182 eV upon irradiation of the experimentally observed (111)-oriented (Ti,Al)N in comparison to the (200)-configuration at similar Ek. Moreover, the effect of Frenkel pair concentration on the thermal stability of metastable c-(Ti,Al)N is investigated by differential scanning calorimetry: Ion-irradiation-induced increase in Frenkel pairs concentration retards the wurtzite formation temperature by up to 206 degrees C.

Smoking and home oxygen therapy : a review and consensus statement from a multidisciplinary Swedish taskforce
- 2024
-
In: European Respiratory Review. - : European Respiratory Society. - 0905-9180 .- 1600-0617. ; 33:171
-
Research review (peer-reviewed)abstract
- Background: Home oxygen therapy (HOT) improves survival in patients with hypoxaemic chronic respiratory disease. Most patients evaluated for HOT are former or active smokers. Oxygen accelerates combustion and smoking may increase the risk of burn injuries and fire hazards; therefore, it is considered a contraindication for HOT in many countries. However, there is variability in the practices and policies regarding this matter. This multidisciplinary Swedish taskforce aimed to review the potential benefits and risks of smoking in relation to HOT, including medical, practical, legal and ethical considerations.Methods: The taskforce of the Swedish Respiratory Society comprises 15 members across respiratory medicine, nursing, medical law and ethics. HOT effectiveness and adverse risks related to smoking, as well as practical, legal and ethical considerations, were reviewed, resulting in five general questions and four PICO (population–intervention–comparator–outcome) questions. The strength of each recommendation was rated according to the GRADE (grading of recommendation assessment, development and evaluation) methodology.Results: General questions about the practical, legal and ethical aspects of HOT were discussed and summarised in the document. The PICO questions resulted in recommendations about assessment, management and follow-up of smoking when considering HOT, if HOT should be offered to people that meet the eligibility criteria but who continue to smoke, if a specific length of time of smoking cessation should be considered before assessing eligibility for HOT, and identification of areas for further research.Conclusions: Multiple factors need to be considered in the benefit/risk evaluation of HOT in active smokers. A systematic approach is suggested to guide healthcare professionals in evaluating HOT in relation to smoking.

Writing resistance together
- 2020
-
In: Gender, Work and Organization. - : John Wiley & Sons. - 0968-6673 .- 1468-0432. ; 27:4, s. 447-470

Journal article (peer-reviewed)abstract
- This piece of writing is a joint initiative by the participants in the Gender, Work and Organization writing workshop organized in Helsinki, Finland, in June 2019. This is a particular form of writing differently. We engage in collective writing and embody what it means to write resistance to established academic practices and conventions together. This is a form of emancipatory initiative where we care for each other as writers and as human beings. There are many author voices and we aim to keep the text open and dialogical. As such, this piece of writing is about suppressed thoughts and feelings that our collective picket line allows us to express. In order to maintain the open-ended nature of the text, and perhaps also to retain some 'dirtiness' that is essential to writing, the article has not been language checked throughout by a native speaker of English.

A Federated Interactive Learning IoT-Based Health Monitoring Platform
- 2021
-
In: New Trends in Database and Information Systems. - Cham : Springer. ; , s. 235-246, s. 235-246
-
Conference paper (peer-reviewed)abstract
- Remote health monitoring is a trend for better health management which necessitates the need for secure monitoring and privacy-preservation of patient data. Moreover, accurate and continuous monitoring of personal health status may require expert validation in an active learning strategy. As a result, this paper proposes a Federated Interactive Learning IoT-based Health Monitoring Platform (FIL-IoT-HMP) which incorporates multi-expert feedback as ‘Human-in-the-loop’ in an active learning strategy in order to improve the clients’ Machine Learning (ML) models. The authors have proposed an architecture and conducted an experiment as a proof of concept. Federated learning approach has been preferred in this context given that it strengthens privacy by allowing the global model to be trained while sensitive data is retained at the local edge nodes. Also, each model’s accuracy is improved while privacy and security of data has been upheld.

ASSERT : A Blockchain-Based Architectural Approach for Engineering Secure Self-Adaptive IoT Systems
- 2022
-
In: Sensors. - basel : MDPI. - 1424-8220. ; 22:18
-
Journal article (peer-reviewed)abstract
- Internet of Things (IoT) systems are complex systems that can manage mission-critical, costly operations or the collection, storage, and processing of sensitive data. Therefore, security represents a primary concern that should be considered when engineering IoT systems. Additionally, several challenges need to be addressed, including the following ones. IoT systems’ environments are dynamic and uncertain. For instance, IoT devices can be mobile or might run out of batteries, so they can become suddenly unavailable. To cope with such environments, IoT systems can be engineered as goal-driven and self-adaptive systems. A goal-driven IoT system is composed of a dynamic set of IoT devices and services that temporarily connect and cooperate to achieve a specific goal. Several approaches have been proposed to engineer goal-driven and self-adaptive IoT systems. However, none of the existing approaches enable goal-driven IoT systems to automatically detect security threats and autonomously adapt to mitigate them. Toward bridging these gaps, this paper proposes a distributed architectural Approach for engineering goal-driven IoT Systems that can autonomously SElf-adapt to secuRity Threats in their environments (ASSERT). ASSERT exploits techniques and adopts notions, such as agents, federated learning, feedback loops, and blockchain, for maintaining the systems’ security and enhancing the trustworthiness of the adaptations they perform. The results of the experiments that we conducted to validate the approach’s feasibility show that it performs and scales well when detecting security threats, performing autonomous security adaptations to mitigate the threats and enabling systems’ constituents to learn about security threats in their environments collaboratively. © 2022 by the authors.

Migrants in Swedish sexual and reproductive health and rights related policies : a critical discourse analysis
- 2022
-
In: International Journal for Equity in Health. - London : BioMed Central (BMC). - 1475-9276. ; 21:1
-
Journal article (peer-reviewed)abstract
- Background: Previous research has shown that migrants in Sweden are disadvantaged in terms of sexual and reproductive health and rights (SRHR). SRHR policies might play a crucial role in shaping migrants’ SRHR outcomes. The purpose of the study was to critically examine: a) how migrants were represented in the discourses embedded within Swedish SRHR-related policies, and b) how migrants’ SRHR-related issues were framed and addressed within these discourses.Methods: Critical discourse analysis (CDA) was used to analyze a total of 54 policy documents. Following Jäger’s approach to CDA, discourse strands and entanglements between different discourse strands were examined.Results: Our findings consisted of three discourse strands: 1) “Emphasizing vulnerability”, 2) “Constructing otherness”, and 3) “Prioritizing the structural level or the individual level?”. Migrants’ representation in Swedish SRHR-related policies is often associated with the concept of vulnerability, a concept that can hold negative connotations such as reinforcing social control, stigma, and disempowerment. Alongside the discourse of vulnerability, the discourse of otherness appears when framing migrants’ SRHR in relation to what is defined as honor-related violence and oppression. Furthermore, migrant SRHR issues are occasionally conceptualized as structural issues, as suggested by the human rights-based approach embraced by Swedish SRHR-related policies. Relevant structural factors, namely migration laws and regulations, are omitted when addressing, for example, human trafficking and HIV/AIDS.Conclusions: We conclude that the dominant discourses favor depictions of migrants as vulnerable and as the Other. Moreover, despite the prevailing human rights-based discourse, structural factors are not always considered when framing and addressing migrants’ SRHR issues. This paper calls for a critical analysis of the concept of vulnerability in relation to migrants’ SRHR. It also highlights the importance of avoiding othering and paying attention to the structural factors when addressing migrants’ SRHR. © 2022, The Author(s).

Providing sexual and reproductive health services to migrants in Southern Sweden : a qualitative exploration of healthcare providers' experiences
- 2022
-
In: BMC Health Services Research. - : BioMed Central (BMC). - 1472-6963. ; 22:1
-
Journal article (peer-reviewed)abstract
- Background: While a large body of research has focused on the challenges experienced by healthcare staff when providing sexual and reproductive health services, little attention has been paid to the ways healthcare providers navigate these challenges. This study examined healthcare providers' accounts of encounters when providing sexual and reproductive health (SRH) services to migrants in Southern Sweden. It sought to examine challenges and dilemmas experienced by healthcare providers, strategies used to navigate these challenges and dilemmas, and assumptions underlying participants' accounts. Methods: The data collection was conducted between September 2020 and March 2021. Qualitative thematic analysis was used to analyze thirty-one interviews with healthcare providers working in youth clinics and women healthcare clinics. The analysis was guided by a conceptual framework combining person-centered care approach, Foucault's concepts on power/knowledge, and theories to navigate diversity in healthcare setting: cultural competency and cultural humility. Results: Three themes were identified in the analysis: 1) Between person centeredness and cultural considerations; 2) Knowledge positions and patient involvement; and 3) beyond the dyadic interaction healthcare provider-patient. Some participants understood person-centered care as individualized care where the influence of culture on the encounter should be de-emphasized, whereas others tended to highlight this influence. Many participants viewed the influence of culture as primarily driven by migrants' cultural backgrounds, and as a source of challenges and dilemmas. Participants' strategies to navigate these perceived challenges and dilemmas included practicing cultural humility and seeking cultural competency. Knowledge positions also emerged as an important aspect of participants' accounts of encounters with migrants. Many participants experienced that migrant patients were lacking knowledge about the body and sexuality. This disadvantaged knowledge position affected migrant involvement in care. Additionally, the study shows how participants placed their experiences in a broader organizational and social context. Participants highlighted several organizational challenges to encountering migrants and discussed dilemmas stemming from the interplay between migrants' structural and individual disadvantages. Conclusions: The study findings illuminate the complex links between person-centered care and two important dimensions of the encounters with migrants: culture and knowledge positions. They also shed the light on the organizational and structural challenges surrounding these encounters. These findings suggest that multilevel strategies are needed to improve the quality of encounters when providing SRH services to migrants. These strategies could include ensuring universal access to SRH services to migrants, adjusting the encounter duration when interpretation is needed, and providing necessary resources to healthcare providers to build their structural competency.

Academic self-efficacy : Associations with self-reported COVID-19 symptoms, mental health, and trust in universities' management of the pandemic-induced university lockdown
- 2022
-
In: Journal of American College Health. - : Informa UK Limited. - 0744-8481 .- 1940-3208.
-
Journal article (peer-reviewed)abstract
- Objective: To investigate perceived changes in academic self-efficacy associated with self-reported symptoms of COVID-19, changes in mental health, and trust in universities’ management of the pandemic and transition to remote education during lockdown of Swedish universities in the spring of 2020. Methods: 4495 participated and 3638 responded to self-efficacy questions. Associations were investigated using multinomial regression. Results: Most students reported self-experienced effects on self-efficacy. Lowered self-efficacy was associated with symptoms of contagion, perceived worsening of mental health and low trust in universities’ capacity to successfully manage the lockdown and transition to emergency remote education. Increased self-efficacy was associated with better perceived mental health and high trust in universities. Conclusion: The initial phase of the pandemic was associated with a larger proportion of students reporting self-experienced negative effects on academic self-efficacy. Since self-efficacy is a predictor of academic performance, it is likely that students’ academic performance will be adversely affected.

Associations between compliance with covid-19 public health recommendations and perceived contagion in others : a self-report study in Swedish university students
- 2021
-
In: BMC Research Notes. - : BioMed Central. - 1756-0500. ; 14:1
-
Journal article (peer-reviewed)abstract
- Objective: During the COVID pandemic, government authorities worldwide have tried to limit the spread of the virus. Sweden's distinctive feature was the use of voluntary public health recommendations. Few studies have evaluated the effectiveness of this strategy. Based on data collected in the spring of 2020, this study explored associations between compliance with recommendations and observed symptoms of contagion in others, using self-report data from university students.Results: Compliance with recommendations ranged between 69.7 and 95.7 percent. Observations of moderate symptoms of contagion in "Someone else I have had contact with" and "Another person" were markedly associated with reported self-quarantine, which is the most restrictive recommendation, complied with by 81.2% of participants. Uncertainty regarding the incidence and severity of contagion in cohabitants was markedly associated with the recommendation to avoid public transportation, a recommendation being followed by 69.7%. It is concluded that students largely followed the voluntary recommendations implemented in Sweden, suggesting that coercive measures were not necessary. Compliance with recommendations were associated with the symptoms students saw in others, and with the perceived risk of contagion in the student's immediate vicinity. It is recommended that voluntary recommendations should stress personal relevance, and that close relatives are at risk.

Does the management of personal integrity information lead to differing participation rates and response patterns in mental health surveys with young adults? A three-armed methodological experiment
- 2021
-
In: International Journal of Methods in Psychiatric Research. - : John Wiley & Sons. - 1049-8931 .- 1557-0657. ; 30:4
-
Journal article (peer-reviewed)abstract
- Objectives: This study evaluates whether initiation rates, completion rates, response patterns and prevalence of psychiatric conditions differ by level of personal integrity information given to prospective participants in an online mental health self-report survey.Methods: A three-arm, parallel-group, single-blind experiment was conducted among students from two Swedish universities. Consenting participants following e-mail invitation answered the World Health Organization (WHO) World Mental Health-International College Student (WMH-ICS) mental health self-report survey, screening for eight psychiatric conditions. Random allocation meant consenting to respond (1) anonymously; (2) confidentially, or (3) confidentially, where the respondent also gave consent for collection of register data.Results: No evidence was found for overall between-group differences with respect to (1) pressing a hyperlink to the survey in the invitation email; and (2) abandoning the questionnaire before completion. However, participation consent and self-reported depression were in the direction of higher levels for the anonymous group compared to the two confidential groups.Conclusions: Consent to participate is marginally affected by different levels of personal integrity information. Current standard participant information procedures may not engage participants to read the information thoroughly, and online self-report mental health surveys may reduce stigma and thus be less subject to social desirability bias.
