Role of Interface Strain and Chemo-Mechanical Effects during Electroplating in Sodium Metal Battery Anodes.

In this study, we demonstrate that elastic strain applied to a current collector can influence the overall thermodynamic and kinetic picture of sodium metal electrodeposition and hence the performance of a sodium metal battery. To controllably study the role of strain in electrochemical performance, we utilize NiTi foil as a stable current collector, nucleation interface, and superelastic material. Our findings demonstrate that a locked-in elastic tensile strain near 8% results in 40 mV lower onset potential for sodium electrodeposition, 19% decrease in charge transfer resistance, and 20% lower cumulative sodium loss, among other effects. These performance improvements are correlated primarily to the control of the irreversible behavior in the first few minutes of electroplating. Given the prevalence of strain buildup in commercial battery cell configurations, our work highlights that strained current collector interfaces can result in significant long-term chemo-mechanical performance outcomes broadly relevant to sodium and other metal battery design considerations.

CT imaging of intrauterine devices (IUD): expected findings, unexpected findings, and complications.

Intrauterine devices (IUDs) are a commonly used form of long-acting reversible contraception, which either contain copper or levonorgestrel to prevent pregnancy. Although symptomatic patients with indwelling IUDs may first undergo ultrasound to assess for device malposition and complications, IUDs are commonly encountered on CT in patients undergoing evaluation for unrelated indications. Frequently, IUD malposition and complications may be asymptomatic or clinically unsuspected. For these reasons, it is important for the radiologist to carefully scrutinize the IUD on any study in which it is encountered. To do so, the radiologist must recognize that normally positioned IUDs are located centrally within the uterine cavity. IUDs are extremely effective in preventing pregnancy, though inadvertent pregnancy risk is higher with malpositioned IUDs. Presence of fibroids or Mullerian abnormalities may preclude proper IUD placement. Radiologists play an important role in identifying complications when they arise and special considerations when planning for an IUD placement. There is a wide range of IUD malposition, affecting IUDs differently depending on the type of IUD and its mechanism of action. IUD malposition is the most common complication, but embedment and/or partial perforation can and can lead to difficulty when removed. Retained IUD fragments can result in continued contraceptive effect. Perforated IUDs do not typically cause intraperitoneal imaging findings.

Renal Mass Imaging with MRI Clear Cell Likelihood Score: A User's Guide.

Small solid renal masses (SRMs) are frequently detected at imaging. Nearly 20% are benign, making careful evaluation with MRI an important consideration before deciding on management. Clear cell renal cell carcinoma (ccRCC) is the most common renal cell carcinoma subtype with potentially aggressive behavior. Thus, confident identification of ccRCC imaging features is a critical task for the radiologist. Imaging features distinguishing ccRCC from other benign and malignant renal masses are based on major features (T2 signal intensity, corticomedullary phase enhancement, and the presence of microscopic fat) and ancillary features (segmental enhancement inversion, arterial-to-delayed enhancement ratio, and diffusion restriction). The clear cell likelihood score (ccLS) system was recently devised to provide a standardized framework for categorizing SRMs, offering a Likert score of the likelihood of ccRCC ranging from 1 (very unlikely) to 5 (very likely). Alternative diagnoses based on imaging appearance are also suggested by the algorithm. Furthermore, the ccLS system aims to stratify which patients may or may not benefit from biopsy. The authors use case examples to guide the reader through the evaluation of major and ancillary MRI features of the ccLS algorithm for assigning a likelihood score to an SRM. The authors also discuss patient selection, imaging parameters, pitfalls, and areas for future development. The goal is for radiologists to be better equipped to guide management and improve shared decision making between the patient and treating physician. © RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Is it time for a paradigmatic shift in relation to healthcare in the UK? A reflection.

CONTEXT: Conflict is a driver of change and unions representing professional groups across the National Health Service (NHS) are currently engaged in direct conflict with the government. For the first time in the history of the NHS, healthcare professionals have taken industrial strike action. Junior doctors and consultant physicians are currently engaged in their respective union ballots and indicative poll surveys regarding potential strike action in the future. In the wake of such widespread industrial action, we have taken time to think deeply about the confronting challenges and issues and offer this reflection as an opportunity to redefine and re-frame an unsustainable healthcare system into one that is the best it can be in terms of fit for purpose. INSIGHTS AND RESOURCE SIGNPOSTING: We present the current context with a reflective framework table focused on 'What do we do well? What is not done so well? What could some possible ideas and solutions be? and How could this change be supported?'We outline how a culture of well-being could be strategically and operationally introduced into the NHS workplace using research-based evidence and practical tools supported by expert guidance.

Urinary Bladder Masses, Rare Subtypes, and Masslike Lesions: Radiologic-Pathologic Correlation.

Urinary bladder masses are commonly encountered in clinical practice, with 95% arising from the epithelial layer and rarer tumors arising from the lamina propria, muscularis propria, serosa, and adventitia. The extent of neoplastic invasion into these bladder layers is assessed with multimodality imaging, and the MRI-based Vesical Imaging Reporting and Data System is increasingly used to aid tumor staging. Given the multiple layers and cell lineages, a diverse array of pathologic entities can arise from the urinary bladder, and distinguishing among benign, malignant, and nonneoplastic entities is not reliably feasible in most cases. Pathologic assessment remains the standard of care for classification of bladder masses. Although urothelial carcinoma accounts for most urinary bladder malignancies in the United States, several histopathologic entities exist, including squamous cell carcinoma, adenocarcinoma, melanoma, and neuroendocrine tumors. Furthermore, there are variant histopathologic subtypes of urothelial carcinoma (eg, the plasmacytoid variant), which are often aggressive. Atypical benign bladder masses are diverse and can have inflammatory or iatrogenic causes and mimic malignancy. © RSNA, 2022 Online supplemental material is available for this article.

Spilling the beans: an inside scoop on the imaging of renal parenchymal disease.

BACKGROUND: Renal parenchymal disease is commonly encountered on imaging, and an understanding of the spectrum of pathology is vital to making correct diagnoses and recommendations for management. These conditions can be categorized based on the presence of calcifications, cysts, solid masses, patterns of enhancement, and other characteristic non-mass findings, as well as on their spatial distribution (i.e., medullary vs. cortical). Making an accurate diagnosis is often challenging, as there is overlap in the features of various diseases, and many benign entities may mimic pathology. OBJECTIVE: This review broadly discusses imaging features of renal parenchymal disease and provides a systematic approach to characterize findings and appropriately guide further management.

Patient Safety and Staff Well-Being: Organizational Culture as a Resource.

The present study examines the relationship between patient safety culture and health workers' well-being. Applying the conservation of resources mechanism, we tested theory-based hypotheses in a large cross-disciplinary sample (N = 3232) from a Taiwanese metropolitan healthcare system. Using the structural equation modeling technique, we found that patient safety culture was negatively related to staff burnout (ß = -0.74) and could explain 55% of the total variance. We also found that patient safety culture was positively related to staff work-life balance (ß = 0.44) and could explain 19% of the total variance. Furthermore, the above relationships were invariant across groups of diverse staff demography (gender, age, managerial position, and incident reporting) and job characteristics (job role, tenure, and patient contact). Our findings suggest that investing in patient safety culture can be viewed as building an organizational resource, which is beneficial for both improving the care quality and protecting staff well-being. More importantly, the benefits are the same for everyone in the healthcare services.

Sickness Presenteeism as a Link between Long Working Hours and Employees' Outcomes: Intrinsic and Extrinsic Motivators as Resources.

The aim of this study was to test the flow from long working hours to sickness presenteeism behavior and its outcomes for employees, while integrating intrinsic and extrinsic work value orientations as moderators in the process. We employed a two-wave design with a five-month interval. Data were obtained from 275 employees in Taiwan. The results of latent moderated structural equations (LMS) revealed that long working hours were positively associated with presenteeism, which in turn was negatively related to employees' well-being and job performance. Furthermore, the negative indirect effect of working long hours on job performance via presenteeism was weaker for those with a higher intrinsic work value orientation. The negative indirect effect of working long hours on well-being via presenteeism was weaker for those with a higher extrinsic work value orientation. We demonstrated that the long-term impact of presenteeism behavior could be understood by viewing work value orientations as resource gains to compensate resource depletion in a demanding work context. This resource dynamism is pivotal to realizing the functional or dysfunctional outcomes of presenteeism behavior. Theoretical and managerial implications of the findings for employees' well-being and organizational effectiveness are discussed.

Dynamic Color Tuning with Electrochemically Actuated TiO2 Metasurfaces.

Dynamic tuning of metamaterials is a critical step toward advanced functionality and improved bandwidth. In the visible spectrum, full spectral color tuning is inhibited by the large absorption that accompanies index changes, particularly at blue wavelengths. Here, we show that the electrochemical lithiation of anatase TiO2 to Li0.5TiO2 (LTO) results in an index change of 0.65 at 649 nm with absorption coefficient less than 0.1 at blue wavelengths, making this material well-suited for dynamic visible color tuning. Dynamic tunability of TiO2 is leveraged in a Fabry-Perot cavity and a gap plasmon metasurface. In the Fabry-Perot configuration, the device exhibits a shift in reflectance of over 100 nm when subjected to only 2 V bias while the gap plasmon metasurface achieves enhanced switching speed. The dynamic range, speed, and cyclability indicate that the TiO2/LTO system is competitive with established actuators like WO3, with the additional advantage of reduced absorption at high frequencies.

Affective Congruence in Visualization Design: Influences on Reading Categorical Maps.

Recent work in data visualization has demonstrated that small, perceptually-distinct color palettes-such as those used in categorical mapping-can connote significant affective qualities. Data that are mapped or otherwise visualized are also often emotive in nature, either inherently (e.g., climate change, disease mortality rates), or by design, such as can be found in visual storytelling. However, little is known about how the affective qualities of color interact with those of data context in visualization design. This article describes the results of a crowdsourced study on the influence of affectively congruent versus incongruent color schemes on categorical map-reading response. We report both objective (pattern detection; area comparison) and subjective (affective quality; appropriateness; preference) measures of map-reader response. Our results suggest that affectively congruent colors amplify perceptions of the affective qualities of maps with emotive topics, affective incongruence may cause confusion, and that affective congruence is particularly influential in maps of positive-leaning data topics. Finally, we offer preliminary design recommendations for balancing color congruence with other design factors, and for synthesizing color and affective context in thematic map design.

Effect of Light Characteristics on the Sensory Properties of Red Lettuce (Lactuca sativa).

Leafy green production in high tunnels (HTs) results in increased yields, improved visual quality, and extended production with polyethylene (poly) film and/or shade cloth coverings. However, altering visible and ultra-violet light with HT coverings may reduce phytochemicals, thus influencing plant pigmentation and taste. The objective of this study was to examine various HT coverings on the sensory perceptions, soil temperature, color, and anthocyanin accumulation of red leaf lettuce. The coverings included standard poly, standard poly with removal two weeks prior to harvest (movable), diffuse poly, clear poly, UV-A/B blocking poly (block), standard poly with 55% shade cloth, and the open field. A highly trained descriptive panel evaluated the samples using a scale from 0 (none) to 15 (extremely high) and determined a list of 20 sensory attributes. The color intensity attribute had the most differentiation between coverings, and the open field was higher (i.e., darker) than the others at 7.5 (p < 0.0001), followed by clear and movable coverings at 6.8, and the shade covering scored a 2. Strong relationships existed between both colorimetric (hue°) and anthocyanin analysis to panelist-based scores (R2 = 0.847 and 0.640, respectively). The initial crispness was similar for movable, standard, diffuse, and block coverings at 5.3 on average, which was higher than the open field at 4 (p < 0.01). The open field lettuce grew under cooler soil temperatures, which may have slowed down maturation and resulted in softer tissue. Based on this study, HT growers can implement specific coverings to cater to markets that value visual quality.

Do Gender and Gender Role Orientation Make a Difference in the Link between Role Demands and Family Interference with Work for Taiwanese Workers?

Based on the gender role orientation perspective, this study extends the resource depletion mechanism that links role demands to family interference with work by testing the moderating effects of gender and gender role orientation (egalitarian vs. traditional) on the relationships. Analysis of the data from 251 employees in Taiwan revealed two significant three-way interactive effects. Specifically, for men, the positive relationship between work demands and family-to-work conflict (FWC) was stronger for egalitarian than traditional individuals. For women, the positive relationship between family demands and FWC was stronger for egalitarian than traditional individuals. We also found a significant two-way interactive effect; that is, within the egalitarian group, the positive relationship between work demands and FWC was stronger for women than men. Our findings, thus, suggest both within-gender and between-gender variations in the links between work-to-family demands and conflict, jointly affected by the individual's gender and gender role orientation. Contextualized within the cultural traditions of a Chinese society, we highlight the precarious position that egalitarian men and women (especially women) find for themselves in fulfilling work duties and family roles. The theoretical and managerial implications are also discussed.

Smart Electromagnetic Thermites: GO/rGO Nanoscale Thermite Composites with Thermally Switchable Microwave Ignitability.

This effort demonstrates the development of a novel, graphene oxide nanoscale thermite composite with thermally tunable microwave ignitability. A model thermite system containing nanoscale aluminum and nanoscale iron(II) oxide in a stoichiometric ratio (30/70 wt %) was combined with sheets of graphene oxide (GO) or reduced graphene oxide (rGO) using an immiscible two-fluid sonication and tape casting process. The samples were microwave irradiated within a single-mode resonant microwave cavity to determine the microwave ignition delay. Neat thermites were found to ignite after 4.34 s of microwave illumination, whereas 30 wt % rGO thermite composite ignition delay was an order of magnitude shorter (0.43 s). For most samples (4 of 6 trials), it was found that application of a 30 wt % GO coating inhibits microwave ignition of the thermite. Thermal treatment of the GO thermite composite led to switching of thermites from unignitable to ignitable with microwave field application as short as 0.24 s due to GO reduction. Optimum heat treatment time and GO content are explored with SEM, DSC/TGA-MS, Raman, and XPS deconvolution. This effort demonstrates the use of GO and rGO addition to achieve thermally switchable microwave ignitability to electromagnetically shield or enhance nanoscale energetic ignition by microwave energy.

Post-Pandemic Patient Safety Culture: A Case from a Large Metropolitan Hospital Group in Taiwan.

Patient safety is the core goal of medical institutions. The present study focuses on the patient safety culture and staff well-being admit the COVID-19 pandemic. In a large metropolitan hospital group, 337 employees who had participated in the quality improvement interventions completed an anonymous questionnaire of patient safety culture and personal well-being. The multiple regression analyses indicated that managerial role, seniority, female gender and direct contact with a patient were significantly related to the positive attitude on overall or certain dimensions of safety culture. Multivariate analysis also found that dimensions of teamwork climate, safety climate, job satisfaction and stress recognition as patient safety culture predicted staff exhaustion. Finally, comparing with the available institutional historic data in 2018, the COVID group scored higher on the working condition dimension of patient safety culture, but lower on the stress recognition dimension. The COVID group also scored higher on exhaustion. In the post-pandemic era, there seems to be an improvement on certain aspect of the patient safety culture among hospital staff, and the improvement is more prevalent for managers. However, exhaustion is also a poignant problem for all employees. These findings can inform hospital decision-makers in planning and implementing future improvements of patient safety culture and promoting employee well-being and resilience. Our findings also reveal directions for future research.

The Compensatory Protective Effects of Social Support at Work in Presenteeism During the Coronavirus Disease Pandemic.

The present study investigated the lasting effects of sickness presenteeism on well-being and innovative job performance in the demanding Chinese work context compounded with the precarities of the post-pandemic business environment. Adopting the conservation of resources (COR) theory perspective, especially its proposition of compensation of resources, we incorporated social resources at work (supervisory support and collegial support) as joint moderators in the presenteeism-outcomes relationship. We employed a panel design in which all variables were measured twice with 6 months in between. Data were obtained from 323 Chinese employees working in diverse industries in Taiwan. We found that after controlling for the baseline level of well-being, presenteeism did not have a lasting effect on employees' exhaustion. However, presenteeism did have a negative lasting effect on employees' innovative behavior 6 months later. Moreover, we found a significant three-way interaction of presenteeism, supervisory support, and collegial support on employees' innovative job performance, after controlling for the baseline level of performance. Specifically, when working under illness, employees displayed the best innovative performance with high levels of both supervisory and collegial support, the worst performance with both support being low, and the intermediate when any one of the support being high. This can be taken as the preliminary evidence to support the COR proposition of resource caravans, showing that supervisory support and collegial support compensated for each other as critical resources in alleviating the impact of working under sickness on employees' innovative performance. Theoretical implications of the findings are discussed, taking into account the macro-cultural context of the East Asian Confucian societies. We also reflected on the managerial implications of the lasting damages of sickness presenteeism and benefits of mobilizing social resources on employees' well-being and performance.

Socially Assigned Gender Nonconformity and School Violence Experience Among Transgender and Cisgender Adolescents.

Although literature documents the experiences of socially assigned gender nonconformity (SAGNC) by minority sexual orientation (i.e., lesbian, gay, and bisexual [LGB]), examination of the role of gender expression on school violence outcomes in the presence of sexual orientation and gender identity is not well understood. This study describes SAGNC among a representative sample of adolescents, accounting for sexual orientation and gender identity (e.g., transgender). A secondary data analysis was conducted using Youth Risk Behavior Survey data from Los Angeles Unified School District high schools in 2013 (N = 1,496). The prevalence of school violence by self-reported SAGNC and gender identity was obtained. Associations between SAGNC and school violence were examined using multivariate logistic regression adjusted for mischievous response bias. Two hundred ninety-one (19.5%) adolescents reported SAGNC. Having missed school due to a safety concern and being bullied in the past year were more common among socially assigned gender nonconforming adolescents than those who conformed to gender expression expectations. Socially assigned gender nonconforming adolescents, regardless of sexual orientation or gender identity, are at greater risk of missed school due to safety concerns, and bullying, as compared with those who conform to norms of gender expression. Future research should measure SAGNC, sexual orientation, gender identity, and expression with larger representative samples of school populations across contexts (urban and rural), and inclusive of structural factors (e.g., school climate) to guide the development of prevention efforts.

Transphobia-Based Violence, Depression, and Anxiety in Transgender Women: The Role of Body Satisfaction.

Psychological processes may mediate the relationship between minority stress and mental health though limited data exist showing this pathway among trans women. Trans women's degree of satisfaction with their body is associated with mental health outcomes. This study used a model of minority stress to explore for indirect effects on the association between transphobia-based victimization and anxiety and depression through one's degree of body satisfaction. Analysis also explored for racial differences. Transgender women (N = 233) were recruited in 2013 using respondent-driven sampling. Sociodemographics, transphobia-based victimization experiences such as having been physically abused, body satisfaction, and mental health were measured. Analyses assessed for direct and indirect associations while controlling for gender confirmation therapies (i.e., cross-sex hormone therapy and gender confirmation surgeries) and racial identity; 57% reported depression and 42.1% reported anxiety diagnoses. Participants averaged nearly three of six assessed violence experiences. More than 20% reported low body satisfaction. Contrary to authors' expectations, those reporting African American and Other racial identity experienced less transphobia-based violence than whites. Transphobia-based violence was significantly associated with anxiety, depression, and body satisfaction. Body satisfaction was associated with mental health diagnoses. Bootstrapping revealed significant indirect and total effects. Body satisfaction mediated the relationship between transphobia-based violence and mental health. Clinical intervention that promotes body satisfaction including access to gender confirmation therapies, especially hormone therapy, may prevent negative mental health outcomes among trans women. Individual intervention, however, is not a panacea for structural discrimination. Attention to structural interventions that reduce gender minority stressors including transphobia-based violence is necessary.

Depression and Suicide Risk at the Cross-Section of Sexual Orientation and Gender Identity for Youth.

PURPOSE: Adolescence is a developmental phase in which young people begin to explore their identity and seek to understand how their identity fits into the larger society. Although this is a developmental task for all adolescents, it is especially salient for sexual and gender minority youth. Owing to oppressive social structures and stigmatized identities, adolescents who identify as nonheterosexual or noncisgender are vulnerable to experiencing disproportionate adverse health outcomes. METHODS: To further the literature on adolescent mental health among sexual and gender minority youth, this study analyzed a representative statewide sample of high school students (ages 14-18) to analyze how sexual orientation and gender identity are associated with depression and suicidality. RESULTS: Results aligned with previous research demonstrating that sexual and gender minority youth were all at a heightened risk for depression. However, transgender youth and youth questioning their sexuality or gender were at especially heightened risk for experiencing depression and suicidality. CONCLUSION: The findings of this study indicate a need to target or adapt direct services and programming for sexual and gender minority adolescents.

Gender Diversity and Work-Life Conflict in Changing Times.

The aim of the study is to contribute to the "well-being, diversity, equity, and inclusion" dialogue of the post-pandemic era. Specifically, we explored the joint effects of biological sex and gender diversity in self-identity on the role demands-work and family conflict relationships. To advance the inclusion of scientific knowledge, the present study was conducted in the cultural context of a Chinese society. We surveyed a sample of 317 Taiwanese employees. We used structured questionnaires to collect data on biological sex, gender identity (self-endorsement on masculinity and femininity traits), work and family demands, work-to-family conflict (WFC), and family-to-work conflict (FWC). We found two sets of significant three-way interactions (sex × femininity × role demands) in predicting work and family conflict. First, for men, identifying with high femininity traits strengthened the positive relationship between work demands and FWC; for women, identifying with low femininity traits strengthened the same relationship. Second, for men, identifying with high femininity traits strengthened the relationship between family demands and WFC; for women, identifying with low femininity traits strengthened the same relationship. Our findings highlight the importance of jointly examining the biological, psychological, and social aspects of gender on the work and family interface. Contextualizing in an Eastern cultural tradition, we put the spotlight on societal pressure on people of nontraditional gender identities.
