The Influence of Regional Geophysical Resource Variability on the Value of Single- and Multistorage Technology Portfolios.

A stylized macro-scale energy model of least-cost electricity systems relying only on wind and solar generation was used to assess the value of different storage technologies, individually and combined, for the contiguous U.S. as well as for four geographically diverse U.S. load-balancing regions. For the contiguous U.S. system, at current costs, when only one storage technology was deployed, hydrogen energy storage produced the lowest system costs, due to its energy-capacity costs being the lowest of all storage technologies modeled. Additional hypothetical storage technologies were more cost-competitive than hydrogen (long-duration storage) only at very low energy-capacity costs, but they were more cost-competitive than Li-ion batteries (short-duration storage) at relatively high energy- and power-capacity costs. In all load-balancing regions investigated, the least-cost systems that included long-duration storage had sufficient energy and power capacity to also meet short-duration energy and power storage needs, so that the addition of short-duration storage as a second storage technology did not markedly reduce total system costs. Thus, in electricity systems that rely on wind and solar generation, contingent on social and geographic constraints, long-duration storage may cost-effectively provide the services that would otherwise be provided by shorter-duration storage technologies.

Catalysis of the Oxygen-Evolution Reaction in 1.0 M Sulfuric Acid by Manganese Antimonate Films Synthesized via Chemical Vapor Deposition.

Manganese antimonate (MnySb1-yOx) electrocatalysts for the oxygen-evolution reaction (OER) were synthesized via chemical vapor deposition. Mn-rich rutile Mn0.63Sb0.37Ox catalysts on fluorine-doped tin oxide (FTO) supports drove the OER for 168 h (7 days) at 10 mA cm-2 with a time-averaged overpotential of 687 ± 9 mV and with >97% Faradaic efficiency. Time-dependent anolyte composition analysis revealed the steady dissolution of Mn and Sb. Extended durability analysis confirmed that Mn-rich MnySb1-yOx materials are more active but dissolve at a faster rate than previously reported Sb-rich MnySb1-yOx alloys.

Compassion Fatigue and Family Caregivers Caring in End-Stage Heart Failure.

Background: Compassion fatigue is a negative consequence impacting caregivers of chronic illness, such as heart failure. Reliance on family caregivers is expected to rise, placing importance on recognizing family caregiver characteristics that contribute to compassion fatigue. Purpose: This study specifically examined the associations of characteristics of family caregivers caring for end-stage heart failure, compassion satisfaction, social desirability, and the family caregiver-nursing provider relationship on compassion fatigue. Methods: An adapted interaction model of client health behavior guided this cross-sectional survey, which comprised a demographic questionnaire, the Professional Quality-of-Life Scale, the caregiver-provider relationship assessment, the Marlowe-Crowne Social Desirability Scale Short Form (Form C), and the Bakas Caregiving Outcomes Scale. Results: There were 127 family caregivers (FCGs), primarily those who have been a caregiver for longer than 1 year (78.4%), who completed the entire survey. Increased compassion satisfaction and positive caregiving effects were associated with decreased compassion fatigue (p < .001), while increased social desirability was associated with increased compassion fatigue (p < .001). A positive family caregiver-nursing provider relationship was related to decreased compassion fatigue (p < .001). More compassion fatigue was seen with lower spiritual status (p < .001). Implications: The chronic progression of heart failure presents opportunities for nursing providers to assess caregivers and offer frequent interventions. Family caregivers may not ask for help. Nursing providers must foster relationships with family caregivers to prevent negative consequences and mitigate compassion fatigue. Future research on the nursing provider relationship and FCGs is needed.

The Impact of COVID-19 on Family Caregivers of Individuals With End-Stage Heart Failure.

Before the COVID-19 pandemic, family caregivers were providing a tremendous amount of care for family members with heart failure with the prevalence of caregiver reliance in heart failure expected to increase in the United States. Social distancing and other restrictions during the COVID-19 pandemic may have added further challenges to caregiving routines. The purpose of this study was to examine the family caregiver perception of the effect of COVID-19 on caregiving routines. To determine caregiver perception of COVID-19's impact, 1 Likert question and 1 open-ended response were asked. Braun and Clark's method guided open-ended response thematic analysis. The 113 replies to the open-response question yielded themes such as social isolation, added fear, anxiety, or worry, changed appointments, wearing masks, and living status change. Social isolation (41.6%) was the most common theme; the most significant theme was living status change ( P = .003), and family caregivers reported that the pandemic affected their routines either negatively or somewhat negatively (62.1%). Family caregivers are affected during times of crisis. Research and policies that recognize the residual effects of COVID-19 on caregiving practices and support care transitions for family caregivers in the heart failure population are needed.

Wind and Solar Resource Droughts in California Highlight the Benefits of Long-Term Storage and Integration with the Western Interconnect.

As reliance on wind and solar power for electricity generation increases, so does the importance of understanding how variability in these resources affects the feasible, cost-effective ways of supplying energy services. We use hourly weather data over multiple decades and historical electricity demand data to analyze the gaps between wind and solar supply and electricity demand for California (CA) and the Western Interconnect (WECC). We quantify the occurrence of resource droughts when the daily power from each resource was less than half of the 39-year daily mean for that day of the year. Averaged over 39 years, CA experienced 6.6 days of solar and 48 days of wind drought per year, compared to 0.41 and 19 for WECC. Using a macro-scale electricity model, we evaluate the potential for both long-term storage and more geographically diverse generation resources to minimize system costs. For wind-solar-battery electricity systems, meeting California demand with WECC generation resources reduces the cost by 9% compared to constraining resources entirely to California. Adding long-duration storage lowers system costs by 21% when treating California as an island. This data-driven analysis quantifies rare weather-related events and provides an understanding that can be used to inform stakeholders in future electricity systems.

An Integrative Review of the LupusQoL Measure.

BACKGROUND AND PURPOSE: Systemic Lupus Erythematosus negatively affects health related quality of life (HRQOL). The purpose of this review is to synthesize and evaluate findings related to the psychometric properties of the LupusQoL and its variations. METHODS: A search of CINAHL, PubMed, and Medline for the timeframe of 2007-2019 for English-language articles using any form of the LupusQoL was completed. Thirty-five studies were reviewed to determine psychometric soundness. RESULTS: Cronbach alpha results supported the internal consistency with test-retest data supporting stability. Factor structure and Scree plots varied. Content, construct, criterion, convergent, and discriminate validity were supported. Ceiling and floor effects occurred. CONCLUSIONS: The LupusQoL and its variations offer a disease-specific measure with supported reliability and validity for use in culturally disparate populations. Factor structure and ceiling/floor effects need further edification.

Validating the Secondary Traumatic Stress Scale for Pediatric Nurses.

BACKGROUND AND PURPOSE: Secondary traumatic stress is a state of mental distress resulting from indirect exposure to the traumatic situation of another individual. The literature indicates that secondary traumatic stress is a problem in some areas of nursing and may cause nurses to leave the profession. This article examines the psychometrics of the Secondary Traumatic Stress Scale (STSS) with a sample of pediatric nurses. METHODS: The STSS was completed by a random sample of 350 Certified Pediatric Nurses. Exploratory and confirmatory factor analyses were completed to assess the STSS and its subscales. RESULTS: Cronbach's αs ranged from 0.81 to 0.87 for each factor, and was 0.92 for the STSS as a whole. Fit indices were similar for all models. CONCLUSIONS: Reliability statistics and fit indices support the previous psychometric studies.

Secondary Traumatic Stress in Pediatric Nurses.

PURPOSE: Secondary traumatic stress affects many in the helping professions, and has been identified in many nursing specialty areas. The purpose of this study was to expand the knowledge of secondary traumatic stress in pediatric nursing by examining the statistical relationships between secondary traumatic stress, age of the nurse, and years of nursing experience, and coping responses. DESIGN AND METHODS: A convenience sample of Certified Pediatric Nurses (n = 338) were surveyed using the Secondary Traumatic Stress Scale, the Brief COPE, the Marlowe-Crowne Social Desirability-Short Form, and a demographics form. Hierarchical multiple linear regression and descriptive statistics were utilized to examine secondary traumatic stress and the other variables of interest. RESULTS: Secondary traumatic stress affected more than half of pediatric nurses surveyed. Age and years of experience did not predict secondary traumatic stress. Looking at coping responses pediatric nurses with higher emotional support and instrumental support scores also demonstrated higher secondary traumatic stress scores. Denial and behavioral disengagement were also associated with an increase in secondary traumatic stress scores. CONCLUSION: Secondary traumatic stress impacts many pediatric nurses. Further research is needed to determine which factors predispose pediatric nurses to secondary traumatic stress and which coping responses help pediatric nurses best manage this stress. PRACTICE IMPLICATIONS: Acknowledging secondary traumatic stress in this population by promoting awareness, and providing educational programs will help to protect nurses' psychological health, and may prevent nurses from leaving the profession due to work-related stress.

Social and Environmental Influences on Physical Activity Levels in Latina Adolescents.

OBJECTIVE: To examine social and environmental factors that affect moderate to vigorous physical activity (MVPA) in mid-adolescent Hispanic females. DESIGN AND SAMPLE: Secondary data analysis to examine social and environmental level factors related to MVPA levels in (n = 897) mid-adolescent Hispanic females. MEASURES: Data were retrieved from the National Survey of Children's Health (2011/12). Logistic regression was used to estimate associations for factors with MVPA. RESULTS: Significant mid-adolescent predictors were English speaking, OR 1.64 (95% CI, 1.03-2.61); parental attendance of activities, OR 0.50 (95% CI, 0.31-0.81); peer support, OR 2.74 (95% CI, 1.75-4.29); supportive neighborhood, OR 1.52 (95% CI, 1.03-2.32); and safe school environment, OR 1.67 (95% CI, 1.01-2.74). CONCLUSION: Findings highlight the need for the development of age and culturally appropriate interventions to aid the improvement of participation levels in MVPA among the Latina adolescent population. Additionally, findings suggest recommendations for policy and future research.

Heterogeneous Chemistry of Lipopolysaccharides with Gas-Phase Nitric Acid: Reactive Sites and Reaction Pathways.

Recent studies have shown that sea spray aerosol (SSA) has a size-dependent, complex composition consisting of biomolecules and biologically derived organic compounds in addition to salts. This additional chemical complexity most likely influences the heterogeneous reactivity of SSA, as these other components will have different reactive sites and reaction pathways. In this study, we focus on the reactivity of a class of particles derived from some of the biological components of sea spray aerosol including lipopolysaccharides (LPS) that undergo heterogeneous chemistry within the reactive sites of the biological molecule. Examples of these reactions and the relevant reactive sites are proposed as follows: R-COONa(s) + HNO3(g) → NaNO3 + R-COOH and R-HPO4Na(s) + HNO3(g) → NaNO3 + R-H2PO4. These reactions may be a heterogeneous pathway not only for sea spray aerosol but also for a variety of other types of atmospheric aerosol as well.

Transitioning from Departments to Schools of Nursing: A Qualitative Analysis of Journeys by Ten Deans.

Transitioning from a department to a school of nursing creates an environment that is more conducive to attracting qualified faculty and enhancing program growth to meet the projected nursing workforce needs. A comprehensive review of the literature revealed limited research to guide nursing programs considering this transition. This qualitative study explored the conditions and outcomes associated with successful or unsuccessful attempts to transition from a department to school of nursing from the perspective of 10 deans affiliated with the American Association of Colleges of Nursing (AACN). Meleis' transitions theory (2010) guided this study in its exploration of facilitating and inhibiting conditions. With institutional review board approval and participant permission, interviews were conducted in-person or by telephone, audio-recorded, and transcribed verbatim. Transcripts were independently reviewed and coded for emerging themes. Content analysis revealed the following themes: titles matter, support is essential, voice at the table, buy-in or dissension, it just brings nursing to totally different level, think differently, and legitimizing your position. For these deans, consideration of the facilitating and inhibiting conditions is critical in determining whether decisions are favorable and in support of the transition. Developing an understanding from the experiences of these 10 deans offers guidance to nursing academic administrators who are contemplating transitioning from a department to a school of nursing. Future research is needed to explore conditions relative to faculty governance and infrastructure, examine the experiences of those undergoing transitions, and expand study findings to develop a self-study guide for programs in assessing their readiness for such a transition.

Trends in central nervous system tumor incidence relative to other common cancers in adults, adolescents, and children in the United States, 2000 to 2010.

BACKGROUND: Time trends in cancer incidence rates (IR) are important to measure the changing burden of cancer on a population over time. The overall IR of cancer in the United States is declining. Although central nervous system tumors (CNST) are rare, they contribute disproportionately to mortality and morbidity. In this analysis, the authors examined trends in the incidence of the most common cancers and CNST between 2000 and 2010. METHODS: The current analysis used data from the United States Cancer Statistics publication and the Central Brain Tumor Registry of the United States. Age-adjusted IR per 100,000 population with 95% confidence intervals and the annual percent change (APC) with 95% confidence intervals were calculated for selected common cancers and CNST overall and by age, sex, race/ethnicity, selected histologies, and malignancy status. RESULTS: In adults, there were significant decreases in colon (2000-2010: APC, -3.1), breast (2000-2010: APC, -0.8), lung (2000-2010: APC, -1.1), and prostate (2000-2010: APC, -2.4) cancer as well as malignant CNST (2008-2010: APC, -3.1), but a significant increase was noted in nonmalignant CNST (2004-2010: APC, 2.7). In adolescents, there were significant increases in malignant CNST (2000-2008: APC, 1.0) and nonmalignant CNST (2004-2010: APC, 3.9). In children, there were significant increases in acute lymphocytic leukemia (2000-2010: APC, 1.0), non-Hodgkin lymphoma (2000-2010: APC, 0.6), and malignant CNST (2000-2010: APC, 0.6). CONCLUSIONS: Surveillance of IR trends is an important way to measure the changing public health and economic burden of cancer. In the current study, there were significant decreases noted in the incidence of adult cancer, whereas adolescent and childhood cancer IR were either stable or increasing.

Developing a dedicated education unit in long-term care: a pilot project.

Within long-term care, the transitional care setting provides post-acute and short-stay rehabilitation to older adults, easing the transition between the acute care hospital and home or long-term care. The current nursing shortage makes it difficult for these facilities to attract and retain qualified nursing staff. In order to meet the rehabilitation needs for this patient population while at the same time addressing the challenge in nursing education of limited clinical placements and severe nurse faculty shortages, an academic-practice partnership was developed to establish a Dedicated Education Unit (DEU). The DEU is an innovative clinical education model in which experienced staff nurses serve as clinical teachers to nursing students. This paper describes the process of developing a DEU using the Partners in Caring Model as the framework. Formative and summative evaluation results and recommendations for program improvement of this pilot project are discussed.

Making healthy connections: introducing nursing as a career choice to middle school students.

The current economic climate has resulted in many experienced nurses returning to the workforce. Despite this, the nursing shortage is looming in our future and the recruitment of a diverse nursing workforce reflective of the population remains a high priority. The Merrimack Valley in northeastern Massachusetts has two large cities, Lawrence and Lowell, in which the Hispanic and the Southeast Asian populations are disproportionately higher than state and national levels. Through the University of Massachusetts Lowell's Bring Diversity to Nursing Project, partnerships with both city school systems were developed and after-school programs aimed at highlighting nursing as a career choice were initiated. Mr. Thompson's Heart is the focus of a middle school, pre-entry program developed by faculty. Introducing career choices in middle school gives students fundamental information about careers and how to begin investigating them. Mr. Thompson's Heart introduces nursing as a career choice combining career information with a focus on developing healthy lifestyle habits. Multiple hands on activities create excitement and interest in the nursing profession.

Sense of humor, childhood cancer stressors, and outcomes of psychosocial adjustment, immune function, and infection.

The diagnosis, treatment, and side effects of childhood cancer have been described as extremely stressful experiences in the life of a child. Anecdotally, children report that a sense of humor helps them cope with the daily experiences of living with cancer; however, no research has examined sense of humor and childhood cancer stressors. This study investigated the effect of sense of humor on the relationship between cancer stressors and children's psychosocial adjustment to cancer, immune function, and infection using Lazarus and Folkman's theory of stress, appraisal, and coping. A direct relationship was observed between sense of humor and psychosocial adjustment to cancer, such that children with a high sense of humor had greater psychological adjustment, regardless of the amount of cancer stressors. A moderating effect was observed for incidence of infection. As childhood cancer stressors increase, children with high coping humor scores reported fewer incidences of infection than low scorers.

Humor: a coping strategy for pediatric patients.

In the past 20 years, nurses have become concerned with children's response to stressors and their ability to cope with them. Humor is one strategy that pediatric nurses can use to help children cope with illness and hospitalizations. Although there is little scientific research, there is some theoretical and anecdotal support for the use of humor as a coping strategy. Understanding the developmental aspect of humor is essential for nurses and families, and McGhee's developmental stages of humor are linked to Piagetian stages of cognitive development. Additional discussion describes related diagnoses, assessment, and outcomes for humor interventions as well as considerations for determining the appropriate and inappropriate use of humor. Numerous activities to implement humor in pediatric clinical settings are presented. The need for further research to evaluate humor intervention as an effective coping strategy is recommended.
