Modeling Rangeland Grasshopper (Orthoptera: Acrididae) Population Density Using a Landscape-Level Predictive Mapping Approach
Authors: Kistner-Thomas Erica , Kumar Sunil , Jech Larry , Woller Derek A 
Published: May 2021

Abstract
Since the mid-19th century, grasshoppers have posed a substantial threat to North American rangelands as well as adjacent croplands and have the potential to cost the economy millions of dollars in annual damages. The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) have gone to great lengths to ensure that rangeland grasshopper populations remain below an economic impact threshold across the western United States. However, current grasshopper forecasting efforts by the USDA are based solely on the previous year’s grasshopper density and do not take region-specific environmental factors (e.g., climate and topography) into account. To better understand the effects of climate and landscape heterogeneity on rangeland grasshopper populations, we assessed the relationship between grasshopper density survey data from across 56 sites between 2007 and 2017 for four counties in north central Wyoming with 72 biologically relevant geographic information system (GIS)-based environmental variables. A regression model was developed to predict mean adult grasshopper density from 2012 to 2016, which was then used to forecast grasshopper density in 2017. The best-fit predictive model selected using Akaike’s Information Criterion (AICc) explained 34.5% of the variation in mean grasshopper density from 2012 to 2016. October precipitation and past mean grasshopper density from 2007 to 2011 were among the best predictors of mean grasshopper density in 2012–2016. Our results also suggest that rangelands in central Sheridan County, southwest Johnson County, and southeast Washakie County are more prone to grasshopper outbreaks. Most importantly, this study demonstrated that both biotic and abiotic environmental variables influence grasshopper density and should be considered in future forecasting efforts.

Abstract
The ectoparasitoid beetle, Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae), has been widely used as a biological control agent for many cerambycid beetles in China, Korea, and Japan. However, much less is known about its phototactic behavior to visual stimuli. In this paper, the phototactic behavioral response of D. helophoroides to 27 monochromatic lights and to nine illumination intensities of the most attractive light was evaluated using light-emitting diodes (LEDs) as light sources. The results showed that in dual choice between darkness and individual LED light, D. helophoroides adults exhibited a positively phototactic response to all wavelengths ranging from 300 to 860 nm. The near-infrared light (NIR, ranging from 700 to 760 nm) elicited stronger phototactic behavioral response, showing a preference for NIR wavelengths light. In paired choice among four preferred NIR lights, D. helophoroides adults displayed a significantly more favorable response to NIR light at 700 nm. Furthermore, the beetles expressed varying levels of sensitivity to illumination intensities from 1 to 600 lux under NIR light at 700 nm. The phototactic response was strongest at 7 lux and a statistically significant downward trend was found with increasing or decreasing the illumination intensities. These findings clearly demonstrate that D. helophoroides is a positively phototactic insect and its phototactic behavior is significantly influenced by light wavelength and illumination intensity, among which NIR light with peak wavelength at 700 nm and an intensity at 7 lux are most suitable in attracting D. helophoroides adults.

Abstract
Facultative endosymbionts can affect the growth, physiology, and behavior of their arthropod hosts. There are several endosymbionts in the invasive whitefly Bemisia tabaci Mediterranean (MED, Q biotype) that influence host fitness by altering stylet probing behavior. We investigated the probing behavior of B. tabaci MED infected with the facultative endosymbiont Candidatus Cardinium hertigii (Cardinium (Sphingobacteriales: Flexibacteraceae)). We generated genetically similar Cardinium-infected (C*+) and uninfected (C-) clonal sublines and analyzed the probing behavior of newly emerged adult on cotton (Malvales: Malvaceae), Gossypium hirsutum L., using electropenetrography (EPG). The C- subline demonstrated a longer duration of E2 (2.81-fold) and more events of E2 (2.22-fold) than the C*+ subline, indicating a greater level of sustained ingestion of plant phloem. These findings provide insight into the fitness costs (fitness of a particular genotype is lower than the average fitness of the population) of the Cardinium-infected B. tabaci.

Published: May 2021

AbstractIntroductionThe proximal femur is a common site for primary sarcomas and metastatic lesions. Although the early results of tumor prostheses are promising, the long-term results of reconstruction are unknown. The purpose of this study is to evaluate the prognostic factors affecting prosthesis survival and complications after proximal femoral resection and reconstruction.MethodsWe reviewed the results of 68 patients who underwent proximal femoral resection and reconstruction with a modular bipolar-type tumor prosthesis between 2005 and 2017. The mean follow-up was 55.6 months (range 6–172 months). There were 50 male and 18 female patients with a mean age of 41.5 years (range 11–80 years). Cumulative survival analysis was performed to analyze the risk factors of prosthesis survival. We also evaluated the complications after operation.ResultsFourteen (21%) patients required further surgery at a mean 37 months post-operatively (range 5–125 months). There were three cases of infection (4%), six of local recurrence (9%), three of acetabular erosion (4%) and two of stem loosening (3%). The implant survival rates were 83.9% at 5 years and 59.8% at 10 years. Prosthesis survivals did not differ based on fixation method (P = 0.085), age (P = 0.329) or resection length (P = 0.61). Acetabular chondrolysis was identified in 18 (26%) patients and longer resection length (≥20 cm) showed a trend for risk of acetabular wear (P = 0.132).ConclusionThe results of proximal femoral resection and reconstruction with a modular bipolar-type prosthesis were found to be acceptable with infection and local recurrence as short-term complications and loosening and acetabular erosion as long-term complications.
Relational Uncertainty Within Relational Turbulence Theory: The Bifactor Exploratory Structural Equation Model
Authors: Goodboy Alan K , Bolkan San , Brisini , Kellie , Solomon Denise Haunani 
Published: May 2021

Abstract
Relational uncertainty consists of self, partner, and relationship uncertainty, which are core parameters in relational turbulence theory (RTT). Advances in latent variable modeling allow researchers to examine the multidimensional construct as a bifactor model, including a general factor of relational uncertainty and residualized factors of self, partner, and relationship uncertainty. This advance is theoretically consequential because RTT maintains the importance of distinctions among the facets of relational uncertainty, even while empirical evidence demonstrates considerable overlap among them. In two data sets (college sample, N = 513; married sample, N = 354), competing measurement models specified Relational Uncertainty Scale items as a unidimensional confirmatory factor model, 3-factor independent clusters confirmatory factor model, 3-factor exploratory structural equation model (ESEM), bifactor confirmatory factor model, and bifactor-ESEM. The bifactor-ESEM provided the best fit in both samples, and bifactor statistics clarified how variance from the scale is partitioned to yield essential unidimensionality for the general factor of relational uncertainty, controlling for its residualized factors. Tests of a latent predictive model using a bifactor specification of relational uncertainty were consistent with RTT. Implications for testing communication theory using bifactor-ESEM are discussed in light of these findings.
Systematic Review and Meta-Analysis of Diagnostic Biomarkers for Pediatric Pneumonia
Authors: Gunaratnam Lourdes Cynthia , Robinson Joan L , Hawkes Michael T 
Published: May 2021

Abstract

Background
Pneumonia causes significant morbidity and mortality in children worldwide, especially in resource-poor settings. Accurate identification of bacterial etiology leads to timely antibiotic initiation, minimizing overuse, and development of resistance. Host biomarkers may improve diagnostic sensitivity and specificity. We assessed the ability of biomarkers to correctly identify bacterial pneumonia in children who present with respiratory distress.

Methods
A librarian-directed search was conducted of MEDLINE, EMBASE, CENTRAL, Global Health, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov to May 2020 with no language restriction. Included studies compared a diagnostic biomarker in children with bacterial pneumonia to those with nonbacterial respiratory distress.

Results
There were 31 observational studies of 23 different biomarkers. C-reactive protein (CRP), procalcitonin (PCT), white blood cell (WBC) count, and erythrocyte sedimentation rate (ESR) were the biomarkers with sufficient data for meta-analysis. Meta-analysis revealed that CRP and PCT best differentiated bacterial from viral pneumonia with CRP summary AUROC (area under the receiver operating characteristic curve) 0.71 (0.69-0.73), Youden index 53 mg/L, sensitivity 0.70 (0.68-0.78), and specificity 0.64 (0.58-0.68) and PCT summary AUROC 0.70 (0.67-0.74), Youden index 0.59 ng/mL, sensitivity 0.69 (0.65-0.77), and specificity 0.64 (0.60-0.68). WBC and ESR did not perform as well. Nineteen other inflammatory and immunologic biomarkers were identified including CRP/mean platelet value, neutrophil/leukocyte ratio, interleukin 6, and interferon-alpha, with sensitivities from 60% to 85% and specificities from 76% to 83%.

Conclusion
CRP and PCT performed better than WBC and ESR but had suboptimal sensitivity. Some less well-studied novel biomarkers appear to have promise particularly in combination.
Extramammary Paget disease: five perianal case report and treatment options
Authors: Deng Heng , Fang Xiaoli , Li Ming 
Published: May 2021

Abstract
We present five cases of perianal Paget disease (PPD). Two cases underwent a wide local excision (WLE) of PPD plus skin flap transfer surgery with good curative effect. One case of PPD complicated with mucinous adenocarcinoma underwent a laparoscopic abdominoperineal resection (Miles), which may be the extremes of clinical treatment of the disease. The remaining two cases passed away without surgery after they refused further treatments. This article aims to draw attention to relationship among the correct diagnosis, protection of anal function and treatment options of PPD.
Characteristic time of stellar flares on Sun-like stars

ABSTRACT
Using the short-cadence data (1-min interval) of the Kepler space telescope, we conducted a statistical analysis for the characteristic time of stellar flares on Sun-like stars (SLS). Akin to solar flares, stellar flares show rise and decay light-curve profiles, which reflect the two distinct phases (rise phase and decay phase) of the flare process. We derived characteristic times of the two phases for stellar flares of SLS, resulting in a median rise time of about 5.9 min and a median decay time of 22.6 min. It is found that both the rise time and the decay time of the stellar flares follow a lognormal distribution. The peak positions of the lognormal distributions for flare rise time and decay time are 3.5 min and 14.8 min, respectively. These time values for stellar flares are similar to the time-scale of solar flares, which supports the idea that stellar flares and solar flares have the same physical mechanism. The statistical results obtained in this work for SLS can be a benchmark of flare characteristic times when comparing with other types of stars.
Robustness of Phylogenetic Inference to Model Misspecification Caused by Pairwise Epistasis
Authors: Magee Andrew F , Hilton Sarah K , DeWitt William S 
Published: May 2021

AbstractLikelihood-based phylogenetic inference posits a probabilistic model of character state change along branches of a phylogenetic tree. These models typically assume statistical independence of sites in the sequence alignment. This is a restrictive assumption that facilitates computational tractability, but ignores how epistasis, the effect of genetic background on mutational effects, influences the evolution of functional sequences. We consider the effect of using a misspecified site-independent model on the accuracy of Bayesian phylogenetic inference in the setting of pairwise-site epistasis. Previous work has shown that as alignment length increases, tree reconstruction accuracy also increases. Here, we present a simulation study demonstrating that accuracy increases with alignment size even if the additional sites are epistatically coupled. We introduce an alignment-based test statistic that is a diagnostic for pairwise epistasis and can be used in posterior predictive checks.
When All You Have is a Hammer: Surface/Depth as Good Comparison
Authors: Sewell Ian 
Published: May 2021

AbstractThis article interrogates and reimagines the approach to reductive music analysis characterized by spatial metaphors (like “underlying” harmony). Such language portrays analysis as the process of discovering a structure “beneath” a piece’s “surface.” I argue that this picture downplays the multi-faceted, varied processes that go into creating musical reductions. Examining details of several different kinds of relationships between “surface” and “depth,” I show that while the traditional characterization is analytically apt in many cases, it encourages false equivalences in others. Borrowing Schoenberg’s description of music theory as being based in “good comparison,” I suggest that such an alternative conception might better suit some of our engagements with reductive analysis. Moreover, adopting this alternative might encourage different kinds of engagements, altering our perspective in a way that makes constructing reductions a much more flexible—and potentially more powerful—approach than has hitherto been the case.

Abstract

Background
Urinary tract infection (UTI) accounts for a substantial portion of outpatient visits and antibiotic prescriptions in the United States. Few studies have considered sociodemographic factors including low socioeconomic status (SES)—which may increase residential crowding, inappropriate antibiotic prescribing, or comorbidities—as UTI or multidrug-resistant (MDR) UTI risk factors.

Methods
We used 2015–2017 electronic health record data from 2 California health care systems to assess whether 3 sociodemographic factors—use of Medicaid, use of an interpreter, and census tract–level deprivation—were associated with overall UTI or MDR UTI. UTIs resistant to ≥3 antibiotic classes were considered MDR.

Results
Analyses included 601 352 UTI cases, 1 303 455 controls, and 424 977 urinary Escherichia coli isolates from Kaiser Permanente Southern California (KPSC) and Sutter Health in Northern California. The MDR prevalence was 10.4% at KPSC and 12.8% at Sutter Health. All 3 sociodemographic factors (ie, use of Medicaid, using an interpreter, and community deprivation) were associated increased risk of MDR UTI. For example, using an interpreter was associated with a 36% (relative risk [RR], 1.36; 95% CI, 1.31 to 1.40) and 28% (RR, 1.28; 95% CI, 1.22 to 1.34) increased risk of MDR UTI at KPSC and Sutter Health, respectively, adjusted for SES and other potential confounding variables. The 3 sociodemographic factors were only weakly associated with UTI overall.

Conclusions
We found low SES and use of an interpreter to be novel risk factors for MDR UTI in the United States.
I cannot picture it in my mind: acquired aphantasia after autologous stem cell transplantation for multiple myeloma
Authors: Bumgardner Adam L , Yuan Kyle , Chiu Alden V 
Published: May 2021

ABSTRACT
Aphantasia, the loss of mental imagery, is a rare disorder and even more infrequent when acquired. No previous cases have been identified that were caused by transplant-related treatment. We describe a case of acquired aphantasia in a 62-year-old male with refractory IgG kappa multiple myeloma after receiving an autologous stem cell transplant (ASCT) following high-dose melphalan with a complicated hospital admission. The etiology of aphantasia remains unidentified, but we provide viable explanations to include direct effects from ASCT treatment and indirect effects from transplant-related complications.

AbstractThe understanding that motherhood impacts career paths is so pervasive among early-career scientists that some feel they must choose parenthood or a career. The penalties associated with motherhood can contribute to the “leaky pipeline,” which equates to the high attrition rate of women due to social, economical, or temporal factors as they proceed through their career and exacerbates persistent gender gaps at mid- and late-career stages. Here, we review the literature and summarize common challenges faced by ornithologist mothers and nonbinary parents, and we adopt a full lifecycle approach to recommend evidence-based strategies for overcoming those challenges. The American Ornithological Society (AOS) is well positioned to support and celebrate women and nonbinary ornithologists who choose parenthood, and we highlight progress made by the AOS to improve gender diversity, equity, and inclusion within the Society. For example, AOS caregiver grants allow more parents to attend and participate in conferences. We suggest additional initiatives (e.g., elevating role models, hosting mentoring networks, and disseminating best practices) that could further support women who want to become or already are parents while also achieving rewarding careers in ornithology. AOS leadership can take steps to close the gender gap in ornithology and other Science, Technology, Engineering, and Mathematics fields. With a larger, more diverse, and talented community, the Society will be better equipped to achieve its mission: conserving and understanding bird life on earth, enriching ornithology as a profession, and mentoring young professionals.

Published: May 2021

AbstractPhotosynthesis is the process conducted by plants and algae to capture photons and store their energy in chemical forms. The light-harvesting, excitation transfer, charge separation and electron transfer in photosystem II (PSII) are the critical initial reactions of photosynthesis and thereby largely determine its overall efficiency. In this review, we outline the rapidly accumulating knowledge about the architectures and assemblies of plant and green algal PSII–light harvesting complex II (LHCII) supercomplexes, with a particular focus on new insights provided by the recent high-resolution cryo-electron microscopy map of the supercomplexes from a green alga Chlamydomonas reinhardtii. We make pair-wise comparative analyses between the supercomplexes from plants and green algae to gain insights about the evolution of the PSII–LHCII supercomplexes involving the peripheral small PSII subunits that might have been acquired during the evolution and about the energy transfer pathways that define their light-harvesting and photoprotective properties.
Jitters on the Eve of the Great Recession: Is the Belief in Divine Control a Protective Resource?
Authors: Upenieks Laura , Schieman Scott , Bierman Alex 
Published: May 2021

AbstractOne factor that has received surprisingly little attention in understanding the mental health consequences of the 2007–2008 financial crisis is religion. In this study, we ask: what is the relationship between two economic stressors—job insecurity and financial strain—and depression? And how do changes in religious belief, indexed by the sense of divine control, moderate those relationships? We use two waves of the U.S. Work, Stress, and Health (US-WSH) project (2005–2007), which occurred on the eve of the Great Recession. Results suggest that increases in job insecurity and financial strain are associated with increased levels of depression. However, those associations are (1) buffered among individuals who simultaneously increased in the sense of divine control and (2) exacerbated among individuals who decreased in the sense of divine control. Moreover, the buffering and exacerbating effects of divine control are significantly stronger among workers with lower levels of education.
Control at Work: An Integrative, Lifespan-Informed Review
Authors: Rauvola Rachel S , Rudolph Cort W 
Published: May 2021

AbstractControl is one of the most ubiquitous and fundamental concepts to the study of psychology, including to theory, research, and practice related to aging and work. Indeed, control constructs exist in many different forms (e.g., self-efficacy, job autonomy, locus of control), and they have been extensively linked to performance and well-being with age. This article provides a review of age- and work-relevant theory and research pertaining to a variety of “actual,” perceived, and enacted control constructs. The article seeks to fulfill 3 goals. First, we review predominant control constructs with respect to theory and research, considering their distinguishing and overlapping features, relationships with age- and work-relevant concerns, and areas of consensus and ambiguity. Second, we synthesize and organize our review findings into a work-focused “lifespan control framework” to guide theoretical revision, hypothesis formation, and construct choice/comparisons, and we provide recommendations to researchers for using this framework. Third and finally, we generate a focused research agenda for impactful studies of age, control, and work. The concept of control has contributed to our knowledge of and practice with work-relevant processes, and this review aims to aid in integration, organization, and innovation to move the study of age, control, and work forward.
