Perception of one's social environment and loneliness: results of the nationally representative "Old age in Germany (D80+)" study.

OBJECTIVES: To examine the association between perception of one's social environment (in terms of residential attachment and neighborhood trust) and loneliness among the oldest old and whether these associations differ by living arrangement. METHODS: We used data from the nationally representative "Old Age in Germany (D80+)" study that included individuals residing in private households and institutionalized settings. The analytic sample was 9,621 individuals (average age: 85.5 years, SD: 4.1 years; 62% female). Data collection took place from November 2020 to April 2021. Multiple linear regressions were conducted with adjustment for relevant covariates. RESULTS: Higher residential attachment (ß=-0.02, p < .05) and higher neighborhood trust (ß=-0.12, p < .001) were associated with less loneliness. The latter association was moderated by living arrangement (ß=-0.09, p = .04) such that the association between neighborhood trust and loneliness was stronger among individuals living in institutionalized settings compared to individuals in private households. CONCLUSION: Greater residential attachment and neighborhood trust, particularly among individuals living in institutionalized settings, are associated with less loneliness among the oldest old. Finding ways to improve perceived attachment and trust may assist in avoiding loneliness among older individuals.

Causal evidence for social group sizes from Wikipedia editing data.

Human communities have self-organizing properties in which specific Dunbar Numbers may be invoked to explain group attachments. By analysing Wikipedia editing histories across a wide range of subject pages, we show that there is an emergent coherence in the size of transient groups formed to edit the content of subject texts, with two peaks averaging at around N = 8 for the size corresponding to maximal contention, and at around N = 4 as a regular team. These values are consistent with the observed sizes of conversational groups, as well as the hierarchical structuring of Dunbar graphs. We use a model of bipartite trust to derive a scaling law that fits the data and may apply to all group size distributions when these are based on attraction to a seeded group process. In addition to providing further evidence that even spontaneous communities of strangers are self-organizing, the results have important implications for the governance of the Wikipedia commons and for the security of all online social platforms and associations.

Pan-cancer γδ TCR analysis uncovers clonotype diversity and prognostic potential.

Gamma-delta T cells (γδ T cells) play a crucial role in both innate and adaptive immunity within tumors, yet their presence and prognostic value in cancer remain underexplored. This study presents a large-scale analysis of γδ T cell receptor (γδ TCR) reads from 11,000 tumor samples spanning 33 cancer types, utilizing the TRUST4 algorithm. Our findings reveal extensive diversity in γδ TCR clonality and gene expression, underscoring the potential of γδ T cells as prognostic biomarkers in various cancers. We further demonstrate the utility of TCR gamma (TRG) and delta (TRD) gene expression from standard RNA-sequencing (RNA-seq) data. This comprehensive dataset offers a valuable resource for advancing γδ T cell research, with implications for enhanced immunotherapy approaches or alternative therapeutic strategies. Additionally, our centralized database supports translational research into the therapeutic significance of γδ T cells.

Income inequality, trust, and depressive symptoms among Chinese adults (CFPS): A causal mediation analysis.

OBJECTIVE: Income inequality has been linked to depressive disorders, but the pathways behind this impact are insufficiently understood. Hence, we aimed to investigate the impact of income inequality on depressive disorders and evaluate the extent to which this impact is mediated by trust. METHODS: Two waves (2012 and 2018) of the China Family Panel Studies (CFPS) were included. Depressive symptoms were assessed using the 8-item Center for Epidemiologic Studies Depression scale (CESD8) and income inequality was measured using the Gini index calculated with household income. Based on the counterfactual framework, causal mediation analysis was applied with the difference-in-difference (DID) method. The sequential ignorability assumption, an important assumption for mediation analysis, was examined by propensity score matching (PSM) and simulation-based sensitivity analysis. RESULTS: Compared to the control group (Change of Gini index ≤0), CESD8 scores in the treatment group (Change of Gini index >0) increase by 0.233 (95 % CI: 0.039, 0.430), which 10.1 % (95 % CI: 3.1 %, 46.0 %) was mediated by reductions in trusts at the provincial level. At the county level, income inequality influences depressive symptoms through the indirect path (ß=0.008, 95%CI: 0.001, 0.020) instead of the direct path (ß= - 0.146, 95%CI: -0.287, 0.000). Dividing the trust, the significant indirect effect appeared in the trust in neighbors, foreigners, government, and doctors at the provincial level. LIMITATION: This study didn't deal with the impact of post-treatment confounders of the mediator-outcome relationship. CONCLUSIONS: Severe income inequality directly and indirectly exacerbated depressive symptoms. Government should carry out the implementation of decreasing income inequality and improving trust.

Perceived environmental uncertainty and job involvement: the mediating role of digital technology and organizational trust - a cross-sectional study in primary care facilities in the UK.

BACKGROUND: Digital maturity can help primary care facilities enhance their processes, communication, and adaptability to change, thereby fostering trust and job involvement. This study aimed to examine the causal relationships between perceived environmental uncertainty, digital maturity, organizational trust, and job involvement among managers of primary care facilities in the UK. The researchers applied socio-technical theory to examine the consequences of technology implementation on work practices and utilized contingency theory to ensure long-term stability in primary care facilities. METHODS: The study was conducted in the second quarter of 2023, surveying 200 managers from primary care facilities in the UK. The survey was conducted using a computer-assisted web interview (CAWI) method based on a purchased panel of respondents. Data were analyzed using descriptive statistics and structural equation modeling. RESULTS: The results showed that perceived environmental uncertainty moderately impacts digital maturity. A greater level of perceived environmental uncertainty is related to greater organizational digital maturity, although perceived environmental uncertainty explains only 15.0% of the variance in digital maturity. The analysis also showed that the impact of digital maturity on organizational trust is positive, significant, and strong, while its impact on job involvement is positive and significant but rather moderate. Moreover, digital maturity mediates the relationship between environmental uncertainty and job involvement among managers of primary care facilities. The weakest link in the model is the connection between organizational trust and job involvement. CONCLUSIONS: The analysis showed that digital maturity is key in shaping organizational trust in primary care facilities and job involvement among their managers. As organizations progress in their digital capabilities, they are better positioned to cultivate trust within their structures. The results of this research contribute to the literature on human resource management in the healthcare sector by deepening knowledge about the impact of environmental uncertainty and digital transformation on organizational trust and job involvement. This study provides important policy information for managers who seek tools to mitigate the adverse effects of environmental uncertainty and want to increase job involvement within primary care facilities.

Understanding the importance of therapeutic alliance during physiotherapy treatment for musculoskeletal pain in children: a scoping review.

Introduction: Musculoskeletal pain affecting children is common. Rehabilitation and treatment effectiveness can be influenced by multiple individual and contextual factors. The need for more rigorous evaluation of physiotherapy treatment for children's pain, identification of the role of specific techniques, and exploration of the influence of the therapeutic alliance is needed. This scoping review of research aimed to examine: (1) What are the perceptions of children, parents, and physiotherapists about the importance of therapeutic alliance during musculoskeletal pain treatment? (2) What are the key characteristics of therapeutic alliance during a child's musculoskeletal pain treatment from the perspectives of children, parents, and physiotherapists? and (3) What are the perceived impacts of therapeutic alliance (positive and negative) during a child's physiotherapy treatment for musculoskeletal pain? Methods: The scoping review, based on Arksey and O'Malley's framework and reporting was guided by PRISMA-ScR. The search strategy was based on three concept blocks: (1) Study population: Children (<18 years); (2) Medical condition: Any musculoskeletal pain (acute, chronic primary, chronic secondary); (3) Intervention: Qualitative exploration of experience of physiotherapy treatment delivered by a physiotherapist from the perspective of a child, parent, or physiotherapist. The search (no date limit) was conducted in February 2024 across Medline, AMED and CINAHL. Results: Following duplicate removal and assessment of eligibility of the initial 236 articles, nine articles were included; of these, only one specifically aimed to explore therapeutic alliance and it was the only paper to directly mention therapeutic alliance. All nine articles presented the child's experience. One overarching theme "Finding resilience within me through therapeutic alliance" and three main themes: "A trusted guide through the ups and the downs of rehabilitation"; "Having a route map"; and "Take me seriously but make it fun" were identified. Discussion: Therapeutic alliance was considered important by children, parents and physiotherapist and it influenced child and parent perceptions of physiotherapy and overall treatment outcomes. Physiotherapists can foster the children's resilience when experiencing musculoskeletal pain by providing disciplinary expertise, connecting and collaborating with the child by becoming their trusted guide, and co-creating a route map for rehabilitation by helping them to learn about their body, pain and recovery timeline.

"Data Free Flow with Trust": Japan's struggle to integrate democracy and human rights into digital trade policy.

A powerful regime for regulating trade, the Group of Seven (G-7) has increasingly negotiated its digital trade through bilateral and preferential trade agreements, including with non-member states in the Global South. Focusing on the dominant concept shaping these agreements, Japan's "Data Free Flow with Trust" (D.F.F.T.), we trace its discursively contested emergence and meaning within a national ("Society 5.0") vision for Japan's digital transformation, and its subsequent transnationalization in international fora and institutionalization in global digital trade policy. Drawing on our interviews with Japanese government ministers, business elites, and legal experts who contributed to the processual development of D.F.F.T., as well as diverse additional primary sources, we find that the D.F.F.T. has become more than a trade policy, covering a wider range of social and geopolitical issues. In particular, we show that contention over "data localization measures" has restructured international relations of trust, especially across the Global North/South divide. Ultimately, this research report contributes to our understanding of how D.F.F.T. poses threats to human rights, democracy, and the global knowledge economy that may undermine its goals of enhancing innovation capacity and economic growth.

Police legitimacy and procedural justice for children and youth: a scoping review of definitions, determinants, and consequences.

Introduction: Understanding police legitimacy among children and youth is important for building a just and democratic society. Although the volume of studies on police legitimacy among underaged persons has grown in recent decades, the findings on the relationships between police legitimacy and procedural justice and their definitions, associated determinants, and consequences remain heterogeneous across studies and across political and legal contexts. Given these heterogeneities, the conclusions and implications generated by this research are far from comprehensive. Method: This scoping review offers readers a comprehensive and comparative understanding of this topic by answering the following questions. (1) How can we define police legitimacy and procedural justice for children and youth? (2) What are the determinants of police procedural justice and legitimacy for children and youth? (3) What are the consequences of police procedural (in)justice and (il)legitimacy for children and youth? (4) Among children and youth, who are the vulnerable groups receiving less legitimate and unjust treatment from the police? A scoping review of the literature published between January 1, 1990 and May 31, 2022 was conducted based on four databases: PubMed, Web of Science, Scopus, and ProQuest. Guided by the scoping review screening framework proposed by Arksey and O'Malley, that is, the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, and the checklist provided by the Joanna Briggs Institute for quality assessment, 47 publications, consisting of 38 quantitative studies and 9 qualitative studies, were retained in the final sample. Results: The results synthesize the operational and subjective interpretations of police legitimacy offered by the respondents in the studies reviewed which is followed by the discussion of conceptual and measurement issues. The key correlates of police legitimacy identified in these studies were police procedural justice and behavior, followed by experience and contact with the police, relationships with other authority figures, and personal competence in moral reasoning and self-control. In addition to compliance and cooperation, cynicism, trust, and health were related to police (il)legitimacy. Discussion: We argue that in addition to building and maintaining police legitimacy, it is vital to remedy the negative consequences of injustice in police-youth encounters.

Perceptions and attitudes toward artificial intelligence among frontline physicians and physicians' assistants in Kansas: a cross-sectional survey.

Objective: This survey aims to understand frontline healthcare professionals' perceptions of artificial intelligence (AI) in healthcare and assess how AI familiarity influences these perceptions. Materials and Methods: We conducted a survey from February to March 2023 of physicians and physician assistants registered with the Kansas State Board of Healing Arts. Participants rated their perceptions toward AI-related domains and constructs on a 5-point Likert scale, with higher scores indicating stronger agreement. Two sub-groups were created for analysis to assess the impact of participants' familiarity and experience with AI on the survey results. Results: From 532 respondents, key concerns were Perceived Communication Barriers (median = 4.0, IQR = 2.8-4.8), Unregulated Standards (median = 4.0, IQR = 3.6-4.8), and Liability Issues (median = 4.0, IQR = 3.5-4.8). Lower levels of agreement were noted for Trust in AI Mechanisms (median = 3.0, IQR = 2.2-3.4), Perceived Risks of AI (median = 3.2, IQR = 2.6-4.0), and Privacy Concerns (median = 3.3, IQR = 2.3-4.0). Positive correlations existed between Intention to use AI and Perceived Benefits (r = 0.825) and Trust in AI Mechanisms (r = 0.777). Perceived risk negatively correlated with Intention to Use AI (r = -0.718). There was no difference in perceptions between AI experienced and AI naïve subgroups. Discussion: The findings suggest that perceptions of benefits, trust, risks, communication barriers, regulation, and liability issues influence healthcare professionals' intention to use AI, regardless of their AI familiarity. Conclusion: The study highlights key factors affecting AI adoption in healthcare from the frontline healthcare professionals' perspective. These insights can guide strategies for successful AI implementation in healthcare.

Can employees' trust their supervisor? The role of high-performance work systems and stewardship climate on employee voice.

The focus of this research is to investigate the factors that influence employee voice behaviour by examining the integration of high-performance work systems, stewardship climate, and trust in supervisor. Drawing on social exchange theory and leader-member exchange, this study investigates the positive relationship between trust in supervisor, high-performance work systems, stewardship climate and employee voice. Data were collected in three stages from 376 Nigerian telecommunications customer-contact employees. Partial Least Squares-Structural Equation Modelling was used to test the dataset. The findings indicate that high-performance work systems have a favourable association with employee voice, while stewardship climate has an adverse correlation with employee voice. Moreover, trust in supervisor is found to mediate and enhance the favourable relationship between high-performance work systems, stewardship climate, and employee voice. The relevance of this study to service industries, management research, and its practical implications is discussed.

Strategically communicating inclusion efforts at hospitals: Trust-signalling for community engagement.

Trust is a challenging and complex concept and takes on particular significance in the context of community engagement and communication in healthcare. For the purpose of making health services more inclusive and of tackling discrimination where it occurs, there is a need to articulate a vision for inclusion that communities of historically disadvantaged or stigmatised patients can trust. This article considers examples of diversity and inclusion 'signals' on the public websites of two large public hospitals in Melbourne, Australia. We suggest that there is value in public communications reaffirming respect for diversity and a commitment to inclusion in health services. We also make the case for interdisciplinary research into how trust-signalling strategies, that is, rhetorical strategies employed to reassure or convince, are developed by and for health services for the purposes of community engagement, and the specific effects that they may engender. Websites' framing of messages that affirm institutional commitments to fostering an inclusive environment and addressing barriers can serve as a means of explicitly encouraging patients and healthcare workers from marginalised communities to overcome potential obstacles to fuller healthcare engagement and workforce participation respectively.

Epistemic Trust: a Keyword for Contemporary Clinical Practice and Psychopathology.

The increasing integration of eclectic knowledge from fields not directly related to clinical psychology is coherent with a current tendency to employ alternative ideas to investigate psychopathology in the light of a more phenomenological perspective. The concept of epistemic trust may provide the gateway to alternative causal models for personality psychopathology that links poor mentalizing environment to a more general lack of social support. People who have been denied the ability to trust the information circulating in their more proximate environment may showcase a remarkable disadvantage in terms of social adjustment that relate to early insecure attachment experiences. Research assumes that patients who have been suffering an epistemic deficient environment in infancy could be trapped into a vicious cycle of suffering, loneliness and inability to seek or accept help. Although most contributes cited in this brief article deal with epistemic trust as potential tool for social learning from a theoretical point of view, the recent introduction of systematic measures of epistemic trust as a dimensional personality variable outlines a likely future increase in the use of new questionnaires and protocols for clinical assessment and treatment monitoring expressively focused on epistemic trust. The benefits of adopting such a holistic etiological paradigm in personality pathology are outlined, as proposed by the many works that advocate a more equitable clinical practice that assume individual development in the context of an unequal social world, that is believed to determine the child's evolutionary trajectory from the very first stages of life. In the same vein, the importance of fostering an authentic relationship of trust between patient and therapist as a fundamental element of the therapeutic alliance, as well as a driving force for salutogenesis at the community level, is vividly highlighted.

How COVID-19 illness perceptions and individual shocks are associated with trust during the COVID-19 pandemic in Australia, France, Germany, and South Africa.

The COVID-19 pandemic jeopardized individuals' health and economic stability, and the associated shocks might have decreased individuals' trust. In this paper, we study the relationship between subjective perceptions of the pandemic and individuals' institutional and interpersonal trust (e.g., trust towards the government or health representatives), while considering objective health and economic shocks due to the pandemic as drivers. We collected data across Australia, France, Germany, and South Africa during a later stage of the COVID-19 pandemic (i.e., from mid-April to early-June 2021) when individuals had time to personally experience the pandemic and its effects. COVID-19 illness perception was associated with lower institutional and interpersonal trust. The health shock of having experienced COVID-19 was associated with higher interpersonal trust, while economic shocks were associated with lower institutional trust when they were due to the pandemic. The results suggest that public policy interventions in a later stage of a pandemic should consider objective economic and health outcomes as well as subjective ones, such as individual's perceptions. Authorities should communicate in a way that helps concerned people understand that they can take control of their health and the possibility of infection, and reassure them that health measures such as vaccination can help prevent the spread of the virus.

Patients' attitudes toward artificial intelligence in dentistry and their trust in dentists.

OBJECTIVES: This study intended to evaluate patients' attitudes toward the use of AI in dental radiographic detection of occlusal caries and the impact of AI-based diagnosis on their trust in dentists. METHODS: A total of 272 completed questionnaires were included in this study. In the first part of the study, approval was obtained from the patients, and data were collected about their socio-demographic characteristics. In the second part the 11-item Dentist Trust Scale was applied. In the third and fourth parts, there were questions about two clinical scenarios, the patients' knowledge of attitudes toward AI, and how the AI-based diagnosis had affected their trust. Evaluation was performed using a Likert-type scale. Data were analyzed with the Chi-square, one-way ANOVA, and ordinal logistic regression tests (p < 0.05). RESULTS: The patients believed that "AI is useful" (3.86 ± 1.03) and were not afraid of the use of AI in dentistry (2.40 ± 1.05). Educational level was considerably related to the patients' attitudes to the use of AI for dental diagnostics (p < 0.05). The patients stated that "dentists are extremely thorough and careful" (4.39 ± 0.77). CONCLUSIONS: The patients displayed a positive attitude to AI-based diagnosis in the dental field and appear to exhibit trust in dentists. The use of Al in routine clinical practice can provide important benefit to physicians as a clinical decision support system in dentistry and understanding patients' attitudes may allow dentists to shape AI-supported dentistry in the future.

Sources of trust in the healthcare context. A multilevel relationship with work engagement and organisational outcomes.

Introduction: The present study analysed the mediating role of interactional justice and horizontal trust between transformational leadership and organisational outcomes (i.e., job performance and service quality) at the work team level and the cross-level relationship of team horizontal trust with job performance at the individual level, controlling for work engagement based on the HERO Model. Methods: Through structural equations and hierarchical linear models, the proposed hypotheses were addressed. The sample corresponds to 1,638 workers grouped into 109 work teams belonging to 28 hospitals in Spain. Results: First, Structural Equation Modelling analysis revealed that, as expected, at the team level, interactional justice and horizontal trust mediate positive and significantly the relationship between transformational leadership and organisational outcomes (i.e., job performance and service quality). Secondly, the results of the Linear Hierarchical Models showed a positive relationship between work engagement and individual level performance. Finally, the multilevel analysis revealed that horizontal trust at the team level is positively related to work engagement at individual level; however, there is no cross-level relationship between horizontal trust at the team level and individual performance controlled by work engagement. Discussion: Horizontal trust, at the team level, is positioned as a mediating variable between resources and organisational outcomes. Furthermore, it proves to be a key cross-level element for generating work engagement and job performance. The theoretical and practical implications of the study based on the HERO Model are discussed.

Engaging with artificial intelligence in mammography screening: Swedish breast radiologists' views on trust, information and expertise.

Objectives: Lack of trust and transparency is stressed as a challenge for clinical implementation of artificial intelligence (AI). In breast cancer screening, AI-supported reading shows promising results but more research is needed on how medical experts, which are facing the integration of AI into their work, reason about trust and information needs. From a sociotechnical information practice perspective, we add to this knowledge by a Swedish case study. This study aims to: (1) clarify Swedish breast radiologists' views on trust, information and expertise pertaining to AI in mammography screening and (2) analytically address ideas about medical professionals' critical engagement with AI and motivations for trust in AI. Method: An online survey was distributed to Swedish breast radiologists. Survey responses were analysed by descriptive statistical method, correlation analysis and qualitative content analysis. The results were used as foundation for analysing trust and information as parts of critical engagements with AI. Results: Of the Swedish breast radiologists (n = 105), 47 answered the survey (response rate = 44.8%). 53.2% (n = 25) of the respondents would to a high/somewhat high degree trust AI assessments. To a great extent, additional information would support the respondents' trust evaluations. What type of critical engagement medical professionals are expected to perform on AI as decision support remains unclear. Conclusions: There is a demand for enhanced information, explainability and transparency of AI-supported mammography. Further discussion and agreement are needed considering what the desired goals for trust in AI should be and how it relates to medical professionals' critical evaluation of AI-made claims in medical decision support.

Persistent pain, long-term opioids, and restoring trust in the patient-clinician relationship.

The erosion of trust in the patient-clinician relationship is an underappreciated, and vital, component of the prescription opioid crisis. Drawing from lived experience of patients and clinicians, and a narrative evidence review, this report discusses how opioid use for persistent pain can impact the patient-clinician relationship from the vantage points of the patient and the family physician. For patients, the stress of dealing with persistent pain, misalignment with clinicians regarding goals of care, experiences of disrespect and stigma, fear of abrupt tapers, and frustration with a fragmented health system, all combine to breed a lack of trust. Clinicians, for their part, experience challenges due to inadequate resources for pain management and opioid safety, pressure to deprescribe opioids rapidly, inconsistent prescribing practices of colleagues, 'policing' opioid prescriptions when concern arises for opioid use disorder and adversarial relationships with frustrated patients wary of clinician intentions. As a result, many clinicians struggle to maintain a therapeutic relationship with patients in great need of empathy and healing. To support implementation of evidence-based guidelines and achieve public health goals of safer prescribing and reducing harm from prescription opioids, we recommend steps health systems and clinicians can take to rebuild trust in the patient-clinician relationship, enable patient-centered pain care, and embed patient perspectives into opioid safety processes. PERSPECTIVE: Erosion of patient-clinician trust is a barrier to implementing evidence-based guidelines that aim to improve opioid safety. This paper explores lived patient and clinician experiences and recommends steps for health systems and clinicians to rebuild this trust as a strategy to actualize the benefits of adherence to these guidelines.

Assessing public trust in road traffic injuries prevention policies in Iran: a cross-sectional study.

INTRODUCTION AND OBJECTIVE: Road Traffic Injuries (RTIs) represent the predominant cause of morbidity and mortality globally. Thus, impactful interventions and trustworthy authorities are imperative to mitigate traffic accidents. The present study seeks to assess public trust in traffic accident diminution policies and measures within the country of Iran. METHOD: This cross-sectional study utilized a questionnaire comprising 31 questions distributed across eight dimensions. The questionnaire's design was informed by a literature review and semi-structured interviews with experts specializing in traffic accidents. The target population consisted of Tabriz city residents, who were selected via convenience sampling. The collected data were then analyzed using SPSS-16 software, employing the T-test, One-way ANOVA, and Pearson correlation coefficient to present the study's results. structural equation modeling (SEM) was conducted using R 4-4-2 programming language. RESULTS: A total of 681 participants completed the questionnaire, yielding a commendable response rate of 88.6%. The majority of participants were male (60.8%), and 86.2% identified as drivers, with 61.8% having experienced driving accidents. The overall score for public trust in RTIs policies was calculated to be 46.9%. The individual scores for specific domains of trust in traffic safety were as follows: safer roads (43.1%), safe vehicle (43.3%), safety laws (48.8%), safe user (51.1%), safe technology (51.5%), road safety management (46.8%). All the latent variables except education are significantly effective on public trust. CONCLUSION: The study findings indicate relatively low levels of public trust in RTIs policies among the Iranian population. These results emphasize the need for targeted interventions to enhance public confidence in specific aspects of traffic safety. Policymakers can use these insights to implement effective measures, thus contributing to the RTIs and the promotion of road safety in the country.

An investigation of perceived risk dimensions in acceptability of shared autonomous vehicles, a mediation-moderation analysis.

The integration of shared and autonomous mobility has led to the emergence of shared autonomous vehicles with ride-sharing services (SAVWRS), which have the potential to significantly reduce private car usage and promote sustainable transportation. Despite numerous studies on this topic, there is still no research examining the impact of all dimensions of perceived risk theory on usage intention. Therefore, we aim to investigate these relationships and gain deeper insights by examining the mediating effect of trust and the moderating effect of generation (Millennials vs. Baby Boomers) to address potential disparities across generations. To gather insights, we design an online survey that was completed by a random sample of 723 individuals in 2021. The estimation results of the structural equation model reveal that all perceived risk dimensions (social, performance, time, physical, security, and financial risks, in descending order) are negatively related to consumers' intention. Additionally, trust fully mediates the relationships between performance, physical, financial, and security risks and usage intention, whereas it partially mediates the relationships between social and time risks and the intention to use. Furthermore, moderation analysis revealed that Millennials are less concerned about most dimensions of perceived risk theory, except for social and time risks. In conclusion, our study contributes to a deeper understanding of the complex relationships between perceived risk dimensions, trust, and usage intention in SAVWRS. Our findings suggest that policymakers and industry stakeholders should consider strategies to address these concerns to promote widespread acceptance of SAVWRS.

The Relationships Between Trust Beliefs in Physicians by Children With Asthma, Those by Their Mothers and the Children's Medical Health.

BACKGROUND: The study examined whether there were linear and curvilinear relationships between the trust beliefs in physicians by the children, those by their mothers and the children's medical health. The study examined whether there were changes in those relationships across time. METHODS: The data gathered in a previous study were subjected to further analyses. One hundred and forty-three children with asthma (116 males, Mage = 12 years and 7 months) and their mothers were administered standardized scales twice across 1 year. The scales assessed the children's trust beliefs in physicians, the mothers' trust beliefs in physicians, the children's quality of life and the children's adherence to prescribed medical regimes. RESULTS: Quadratic relationships were found between the children's quality of life and both their and their mothers' trust beliefs in physicians. The quadratic relationship increased over time. Linear relationships were found between trust beliefs in physicians and children's adherence to prescribed medical regimes. CONCLUSION: Children with asthma are prone to a lower quality of life when they and their mothers hold very high, as well as hold very low, trust beliefs in physicians. Children's trust beliefs in physicians increase the probability of adherence to prescribed medical regimes.
