Focused on the Family: Development of a Family-Based Intervention Promoting the Transition to Adult Health Care for Adolescents with Type 1 Diabetes.

Background/Objectives: There is minimal evidence for current interventions promoting the transition to adult healthcare for youth with type 1 diabetes (T1D). Few interventions exclusively target modifiable individual and family-based factors that contribute to transition readiness. The purpose of this paper is to describe the development of Behavioral Family Systems Therapy for Diabetes Transition (BFST-DT), a virtual family-based transition readiness intervention for adolescents with T1D. Methods: The development of BFST-DT occurred in three phases. In phase 1, focus groups with adolescents and young adults with T1D, their caregivers, and pediatric and adult diabetes providers were conducted to assess perspectives on common family challenges surrounding diabetes management and the transition to adult healthcare. In phase 2, focus group data were used to create video vignettes to be used as part of the intervention. In phase 3, BFST-DT was created through the adaptation of a previous evidence-based family intervention for families of adolescents with T1D. Results: BFST-DT is a virtual, 6-month family-based intervention involving four multi-family group meetings and six individual family meetings. It targets the modifiable and reciprocal interactions among individual and family transition readiness factors. Conclusions: BFST-DT is the first family-focused intervention promoting transition readiness in adolescents with T1D and is currently being tested. Intervention development benefits from prioritization of engagement with patients, caregivers, and providers, as their perspectives are invaluable for creating interventions that are relevant and acceptable to communities.

Quantized Integrated Shift Effect in Multigap Topological Phases.

We show that certain three-dimensional multigap topological insulators can host quantized integrated shift photoconductivities due to bulk invariants that are defined under reality conditions imposed by additional symmetries. We recast the quantization in terms of the integrated torsion tensor and the non-Abelian Berry connection constituting Chern-Simons forms. Physically, we recognize that the topological quantization emerges purely from virtual transitions contributing to the optical response. Our findings provide another quantized electromagnetic dc response due to the nontrivial band topology, beyond the quantum anomalous Hall effect of Chern insulators and quantized circular photogalvanic effect found in Weyl semimetals.

Transition to Adulthood through Coaching and Empowerment in Rheumatology (TRACER): A feasibility study protocol.

The transition from pediatric to adult care for patients with chronic disease is a vulnerable period, with risks of disengagement from care and subsequent complications of inadequately managed disease. This period comes at a time when there are many other transitions occurring in the young person's life, including changes to vocation, social supports, and to their physiology. The aim of the TRACER study is to assess the feasibility of conducting a multi-center, randomized-controlled trial of a virtual Transition Coach Intervention in youth transferring from pediatric to adult rheumatology care. Patients are being recruited at their last pediatric rheumatology visit from McMaster Children's Hospital and Children's Hospital, London Health Sciences Centre in Ontario, Canada. Participants are then randomized to standard of care or to eight transition coaching sessions, covering topics around health management, future planning, and self-advocacy. The primary outcomes of the study are to demonstrate protocol feasibility, including optimal recruitment and consent rates, ≥ 90% coaching session completion, and complete data collection with ≤ 5% missing data. Baseline demographics, transition readiness, global functional assessment, disease activity, and self-efficacy will be collected to characterize the study population. Recruitment has begun and is estimated to last 19 months. This study will inform the design of a robust, multi-centered, randomized-controlled study to investigate the impact of a virtual transition coaching program in supporting the physical, mental, and social well-being of youth with rheumatic disease transitioning into adult care.

Cyanobiphenyl-based liquid crystal dimers and the twist-bend nematic phase: on the role played by the length and parity of the spacer

ABSTRACT Six members of the 1,ω-bis(4-cyanobiphenyl-4′-yl) alkanes are reported and referred to as CBnCB in which n = 1, 15, 16, 17, 19 and 20 and indicates the number of methylene units in the spacer separating the two cyanobiphenyl units. The behaviour of CB3CB is revisited. The temperature dependence of the refractive indices, optical birefringence and dielectric permittivities measured in the nematic, N, phase for selected homologues are reported. The dimers with n ≥ 15 showed an enantiotropic N phase, and for the odd members the twist-bend nematic, NTB, phase was observed. CB3CB shows a direct NTB-isotropic, I, transition, whereas for CB1CB a virtual NTB-I transition is found. The temperature dependence of the bend elastic constant, K 33 , measured in the oblique helicoidal cholesteric state formed by mixtures of CBnCB with a chiral additive S811, shows strong non-monotonous behaviour with a deep minimum near the transition point to the NTB phase. The minimum value of K 33 decreases as n increases. The long even members of the CBnCB series show similar values of TNI to their odd-membered counterparts, but their estimated values of TNTB N are considerably lower. This is attributed to molecular shape and its effect on K 33 .

Virtual walks and phase transitions in the two-dimensional Biswas-Chatterjee-Sen model with extreme switches.

In kinetic exchange models of opinion formation, one considers pairwise interactions to update the states of the agents. We have studied a kinetic exchange model with three opinion states 0,±1, by considering a walk in a one-dimensional virtual space which evolves according to the dynamical states of the agents. The model involves two noise parameters p and q; p represents the fraction of negative interactions and q corresponds to the probability of a stronger interaction with the other agent, which may result in extreme switches (change of state from +1 to -1 or vice versa). The nature of the walks can indicate where the phase transitions occur in the p-q plane; these results are corroborated with those obtained using finite-size scaling method. The criticality is found to be Ising-like, even when extreme switches are allowed. A new critical exponent associated with the probability distribution of the displacements in the virtual space is also obtained independent of the values of the critical parameters. The nature of the walks is compared to similar virtual walks studied earlier.

Enhancing shift current response via virtual multiband transitions

Materials exhibiting a significant shift current response could potentially outperform conventional solar cell materials. The myriad of factors governing shift-current response, however, poses significant challenges in finding such strong shift-current materials. Here we propose a general design principle that exploits inter-orbital mixing to excite virtual multiband transitions in materials with multiple flat bands to achieve an enhanced shift current response. We further relate this design principle to maximizing Wannier function spread as expressed through the formalism of quantum geometry. We demonstrate the viability of our design using a 1D stacked Rice-Mele model. Furthermore, we consider a concrete material realization - alternating angle twisted multilayer graphene (TMG) - a natural platform to experimentally realize such an effect. We identify a set of twist angles at which the shift current response is maximized via virtual transitions for each multilayer graphene and highlight the importance of TMG as a promising material to achieve an enhanced shift current response at terahertz frequencies. Our proposed mechanism also applies to other 2D systems and can serve as a guiding principle for designing multiband systems that exhibit an enhanced shift current response.

Perceptions of virtual versus in‐person recovery meetings: A cross‐sectional survey of Oxford House residents

AbstractThis study investigates shifts in the modality of addiction recovery communities from person‐to‐person interactions to virtual platforms in the context of the coronavirus disease of 2019 (COVID‐19) pandemic. Our study involves members of the Oxford House recovery homes (n = 284), a major network of recovery‐supportive housing in the United States and abroad. Many residents participate in 12‐step meetings during their stay, traditionally conducted in‐person, but due to physical distancing regulations, many of these meetings transitioned to virtual platforms. We collected cross‐sectional survey data focusing on user perceptions of virtual 12‐step meetings in terms of accessibility, cost, convenience, support network strength and recovery network quality. Our study found significant differences in perceptions among different demographic groups, suggesting challenges in transitioning recovery support to online platforms. Notably, participants aged 46 and older showed a greater propensity to use online recovery forums and found online meetings convenient. Non‐White individuals and women demonstrated a more favourable perception of online meetings—a trend that also held true among those with at least some college education. Furthermore, the results show that those who initiated their recovery prior to the COVID‐19 lockdown viewed online methods more favourably, particularly in terms of accessibility and cost. Our data also revealed that participants who were categorically involved in 12‐step recovery (Alcoholics Anonymous/Narcotics Anonymous) demonstrated a more positive perception of online methods in terms of the strength of social networks and social support quality, despite some resistance to virtual transition and maintaining focus. Further research is needed to understand these nuanced impacts and develop strategies to enhance the effectiveness of online recovery meetings.

Virtuality in Modern Physics in the 1920s and 1930s: Meaning(s) of an Emerging Notion

Abstract This article discusses the meaning of the notion of virtuality in modern physics. To this end, it develops considerations on the introduction and establishment in nuclear physics of two independent concepts at the turn of the 1920s and 1930s: that of the virtual state, used in the context of neutron scattering studies, and that of the virtual transition, useful for the theoretical understanding of strong nuclear forces, which forms the basis of what are now called virtual particles. Their comparative analysis highlights the theoretical nature of virtual entities and processes in modern physics. It also shows how the virtual has been associated with various purely physical attributes, leading to a form of polysemy of the term, from the beginning of the application of these concepts.

B63: The Most Stable Bilayer Structure with Dual Aromaticity.

The emergence of a bilayer B48 cluster, which has been both theoretically predicted and experimentally observed, as well as the recent experimental synthesis of bilayer borophene sheets on Ag and Cu surfaces, has generated tremendous curiosity in the bilayer structures of boron clusters. However, the connection between bilayer boron cluster and bilayer borophene remains unknown. By combining a genetic algorithm and density functional theory calculations, a global search for the low-energy structures of the B63 cluster was conducted, revealing that the Cs bilayer structure with three interlayer B-B bonds is the most stable bilayer structure. This structure was further examined in terms of its structural stability, chemical bonding, and aromaticity. Interestingly, the interlayer bonds induce strong electronegativity and robust aromaticity. Furthermore, the dual aromaticity stems from diatropic currents originating from virtual translational transitions for both σ and π electrons. This unprecedent bilayer boron cluster is anticipated to enrich the concept of dual aromaticity and serve as a potential precursor for bilayer borophene.

The traditional aesthetic education model is limited by the lack of time and space and interaction. The virtual reality technology is based on its immersive and interactive characteristics. Provides new possibilities. Elapse the aesthetic education from three aspects: immersive experience, interactive teaching and time and space reshaping. Through the comparative analysis of the case, the actual application and innovation teaching model of virtual reality technology in aesthetic education is discussed, and the virtual reality technology and aesthetic education are better integrated to provide more effective and innovative ways to cultivate students' aesthetic ability.

The effect of virtual visual scene inclination transitions on gait modulation in healthy older versus young adults-A virtual reality study.

Bipedal locomotion requires body adaptation to maintain stability after encountering a transition to incline walking. A major part of this adaptation is reflected by adjusting walking speed. When transitioning to uphill walking, people exert more energy to counteract gravitational forces pulling them backward, while when transitioning to downhill walking people break to avoid uncontrolled acceleration. These behaviors are affected by body-based (proprioception and vestibular) cues as well as by visual cues. Since older age adversely affects walking, it is unclear whether older adults rely on vision during locomotion in a similar manner to younger individuals. In this study, we tested whether the influence of visual cues on these walking speed modulations in healthy older adults (60-75 years old, N = 15) were comparable to those found in healthy young adults (20-40 years old, N = 12). Using a fully immersive virtual-reality system embedded with a self-paced treadmill and projected visual scene, we manipulated the inclinations of both the treadmill and the visual scene in an independent manner, and measured participants walking speed. In addition, we also measured individual visual field dependency using the rod and frame test. The older adults presented the expected braking (decelerating) and exertion (accelerating) effects, in response to downhill and uphill visual illusions, respectively, in a similar manner to the young group. Furthermore, we found a significant correlation between the magnitude of walking speed modulation and visual field dependency in each of the groups with significantly higher visual field dependency in older adults. These results suggest that with aging individuals maintain their reliance on the visual system to modulate their gait in accordance with surface inclination in a manner similar to that of younger adults.

Graduating Medical Students' Perceptions of the COVID-19 Pandemic's Impact on Their Medical School Experiences and Preparation for Careers as Physicians: A National Study.

The COVID-19 pandemic resulted in unprecedented changes to the medical education learning environment. The graduating class of 2021 was particularly affected. To better understand how students were affected, the authors explored positive and negative experiences described by graduating U.S. medical students. Using the conceptual framework of affordances, the authors examined narrative responses to 2 new open-ended questions on the Association of American Medical Colleges 2021 Graduation Questionnaire in which graduating students described the pandemic's positive and negative effects on their medical school experiences and career preparation. Conventional content analysis was used to identify affordances and themes in responses. Of 16,611 Graduation Questionnaire respondents, 8,926 (54%) provided narrative responses. Of these 8,926 respondents, responses from 2,408 students (27%) were analyzed. Students described positive and negative perceptions of affordances, centering around virtual learning, social connection, and transition to residency. Fewer in-person and increased virtual clinical rotations offered students flexible scheduling, allowing them greater opportunity to explore academic and professional interests. Additionally, students' sense of isolation from their medical school was alleviated when schools exercised intentional open communication and student involvement in decision-making. Although many described a diminished sense of preparedness for residency due to limited access to in-person clinical experiences and to assessing residencies largely through virtual away rotations and interviews, the sense of community, adaptability, and resiliency gained through varied activities reinforced students' professional identity and commitment to medicine during a time of much uncertainty. This national exploration of students' pandemic experiences highlights what students value as fundamental elements of medical education and student support and describes how innovation can improve long-standing practices. These findings, guided by students' insights, can help inform the work of educational leaders as they consider which innovations should remain to continue enhancing student learning, engagement, and well-being.

Exploring Clients' Experiences of Transitioning Mental Health Nursing Care from an In-Person to a Virtual Format due to the COVID-19 Pandemic.

The onset of the COVID-19 pandemic led mental health professionals to change the way they engaged with clients, often replacing in-person consultations with virtual ones via telephone or videoconferencing. While studies have investigated the delivery of virtual physical health care, only a handful have investigated the delivery of virtual mental health. These specifically focussed on the outcomes of virtual care whether experiential, practical, or empirical. The transition from in-person to virtual care delivery due to the COVID-19 pandemic has been unexplored. Accordingly, the purpose of the study was to: (1) Explore the experiences of clients who had to transition from an in-person to a virtual provision of mental health care due to the COVID-19 pandemic, and; (2) Explore the nurses' experiences of this technological transition. Using an interpretive phenomenology methodology, semi-structured interviews were conducted with nurses and clients who have experienced the in-person to virtual transition of service delivery at a tertiary mental health hospital in Ontario, Canada. In this article, we focus on the results stemming from our interviews with clients. The themes generated from the analysis of client experiences are 1) the psychosocial impact of the COVID-19 pandemic on clients, (2) mixed feelings of clients towards nursing care delivered via technological means and (3) the role of nurses regarding transitioning of in-person care to technology-mediated care. These findings are relevant as mental health care hospitals are considering how they will deliver services once concerns with the transmission of the COVID-19 virus are resolved.

Modeling the user experience in virtual and real world transition by understanding the user goal value

Recent advancements in social computing have led to a significant impact on the boundary between the virtual and real worlds. This study explores the virtual world within digital games, using a mean-end chain model and the laddering method to conduct in-depth interviews. It was found that Convenience, Interactions with others, and Ease of use, were the main design attributes for users. The main consequences for the user are discovered to be the Sense of physical presence and Physical or emotional reality is affected. Important values sought by the player are Self-fulfillment and Make life easier. Interestingly, while virtual worlds can have positive effects on users' real lives, they also introduce negative consequences, such as desensitization. In response to these findings, initial steps are proposed to address this issue, including the creation of a structural framework for users transitioning between virtual and real worlds. This framework offers theoretical guidance for future game product development in three-dimensional virtual environments, ultimately enhancing the player experience.

Social workers' formal and informal leadership in interprofessional primary care teams in Ontario, Canada.

The development of interprofessional teams in primary care presents opportunities for social workers to take on new leadership positions. This study seeks to describe how social workers engaged in leadership roles in primary care during the COVID-19 pandemic. A cross-sectional on-line survey was disseminated to primary care social workers across Ontario, Canada, with a total of 159 respondents. Most respondents engaged in informal leadership roles and showcased a range of leadership skills promoting team collaboration and consultations, along with adapting to virtual care transitions. Findings suggest there needs to be intentional cultivation of social work leaders through supportive environments and training. Social workers in primary care have leadership capacity and are providing leadership to their primary care teams through formal and informal means. The leadership potential of social workers in primary care teams, however, is being underutilized and can be further developed.

General nonlinear Hall current in magnetic insulators beyond the quantum anomalous Hall effect

Can a generic magnetic insulator exhibit a Hall current? The quantum anomalous Hall effect (QAHE) is one example of an insulating bulk carrying a quantized Hall conductivity while insulators with zero Chern number present zero Hall conductance in the linear response regime. Here, we find that a general magnetic insulator possesses a nonlinear Hall conductivity quadratic to the electric field if the system breaks inversion symmetry, which can be identified as a new type of multiferroic coupling. This conductivity originates from an induced orbital magnetization due to virtual interband transitions. We identify three contributions to the wavepacket motion, a velocity shift, a positional shift, and a Berry curvature renormalization. In contrast to the crystalline solid, we find that this nonlinear Hall conductivity vanishes for Landau levels of a 2D electron gas, indicating a fundamental difference between the QAHE and the integer quantum Hall effect.
