Authors: Murphy P. Karen , Croninger Rachel M. V. , Baszczewski Sara E. , Tondreau Cory L. 
Published: May 2022

AbstractClassroom discussions are regarded by both practitioners and researchers as an essential pedagogical practice for fostering students' high‐level comprehension of text yet cultivating a dialogic classroom culture conducive to supporting students' productive talk can be a delicate undertaking. In this article, using a series of transcripts from one teacher's classroom, we describe how Quality Talk (QT), a teacher‐facilitated discussion approach, can be implemented in ways that promote a shift from a teacher‐controlled to a student‐centered dialogic classroom culture. First, we overview the QT model with particular attention to the instructional framework and underlying principles of QT. We then describe some challenging dynamics that arise when dialogic classroom culture shifts as well as approaches for balancing these opposing forces to effectively support student learning. Finally, we provide some initial thoughts on next steps in classroom discussion practice and research and the importance of centering equity and inclusion in dialogic classroom culture.

Published: May 2022

AbstractBackgroundAge‐related dementia has been documented in domestic cats; however, its interaction with naturally occurring feline immunodeficiency virus (FIV) infection has been investigated minimally.MethodsVisuospatial working memory (VSWM) and problem‐solving (PS) ability were evaluated in FIV‐infected (n = 37) and control cats (n = 39) using two cognitive tasks tested serially, which assessed the ability of cats to remember the location of a baited container after a set delay, then evaluated the capability of the cats to manipulate the container to obtain the food within a time limit. Cats were categorized using 7 years of age as a cut‐off to determine age‐related differences. The relationship between cognitive performance and FIV viral load was investigated using real‐time PCR cycle threshold (Ct) values.ResultsAge significantly affected VSWM and PS ability. Younger cats had better VSWM performance and PS ability compared to older cats with the same FIV status. There was no difference between younger FIV‐positive and negative cats in either part of the task. While older FIV‐positive cats had significantly worse VSWM than older FIV‐negative cats, no differences were found in PS ability. Additionally, Ctvalues predicted VSWM but not PS ability.ConclusionAge‐related cognitive impairments and FIV infection appear synergetic, causing greater cognitive deficits in older FIV‐infected cats.

AbstractMonitoring of wild turkey (Meleagris gallopavo) females to obtain representative measures of apparent nesting and nest survival rates has long been an important component of wild turkey management. In the interest of improving estimates of apparent nesting and nest survival rates, we assessed the feasibility of inferring reproductive behavior of wild turkeys from remotely acquired movement data. We ascertained detailed nesting stage chronologies using Global Positioning System (GPS) data downloaded from 44 females fitted with transmitters that had both a very high frequency (VHF) beacon and a GPS logger. Then we tracked females using VHF to confirm nest locations and nest fate in north and north‐central Florida. Using twice hourly GPS derived locations, we evaluated 3 predictive machine learning models (Chi‐squared automatic interactive detection [CHAID], exhaustive CHAID, and multivariate adaptive regression splines [MARSpline]) for their ability to accurately classify nesting behaviors (laying and incubating stages) that were confirmed via visual inspection of all potential nest sites. Incubation stage was readily identifiable by the spatial signatures present in each female's GPS‐based movement track across all models (up to 92% true positive and as low as 8% false positives in exhaustive CHAID models), whereas the laying stage was more difficult to identify (up to 65% true positive and as low as 35% false positives in exhaustive CHAID models). Daily averages of movement metrics generally achieved better performance in predictive models than data sets with more frequent sampling (i.e., 30‐minute daytime locations). Our results indicated that exhaustive CHAID models performed best in identifying nesting stages, using movement metrics from GPS data. With continued development, these models may facilitate and improve large‐scale wild turkey monitoring.
Historical and potential growth of Gould's wild turkey populations in New Mexico
Authors: Lerich Scott P. , Cardinal Casey J. 
Published: May 2022

AbstractGould's wild turkeys (Meleagris gallopavo mexicana) are native to the southwest corner of New Mexico, southeastern Arizona, and northern and central Mexico. Early ornithological explorations of southwestern New Mexico documented the presence of turkeys, but the subspecies was not identified as Gould's wild turkeys until 1957. Although extirpated from Arizona by 1920, a remnant population of Gould's wild turkeys persisted in the Peloncillo and Animas mountains in New Mexico, possibly due to recolonization from or genetic exchange with proximal populations in Mexico. The New Mexico Department of Game and Fish placed Gould's wild turkey on the State Endangered and Threatened list in 1974. Research and monitoring during the mid‐1980s through early 2000s largely focused on observational studies of Gould's wild turkey distribution, abundance, and habitat use. Since 2005, population status and distribution of Gould's wild turkeys in the Peloncillo Mountains was monitored using structured, annual surveys that provided greater insight into minimum population size. From January 2014 to January 2016, the population in the southern Peloncillo Mountains was augmented with the translocation of 60 Gould's wild turkeys from southeastern Arizona. Annual observations of Gould's wild turkeys increased following the 2014–2016 translocations in part due to the ability to detect radio‐marked individuals and identify previously unknown habitats birds were using, allowing for modified survey efforts. Although information on Gould's wild turkey distribution and abundance has increased since 1980, much of the available habitat is currently considered occupied, and future population distribution may be limited.
Mild Hyperthermia Induced by Water-Filtered Infrared A Irradiation: A Potent Strategy to Foster Immune Recognition and Anti-Tumor Immune Responses in Superficial Cancers?
Authors: Multhoff G. , Repasky E. A. , Vaupel Peter 
Published: May 2022

AbstractApart from a number of positive “physiological” effects such as an increase in local blood flow which results in an improved oxygen supply and a reversal of tumor hypoxia, a key hallmark of cancer growth which greatly impairs anti-tumor immune responses, hyperthermia (HT) also exerts beneficial effects on anti-cancer immunity. The water-filtered infrared A (wIRA) irradiation technique achieves tissue temperatures in the fever-range (tT = 39–41 °C) or mild hyperthermia levels (tT = 39–43 °C) up to tissue depths of ≈25 mm in tissues. At tissue temperatures of 39–43 °C, by fostering the reactivity of the “immunological” TME [e.g., the activity of CD8+cytotoxic T cells, CD4+helper T cells, dendritic cells (DC), M1 macrophages, natural killer (NK) cells, and NK-like T (NK-T) cells], while compromising immunosuppressive cells [e.g., tumor-associated M2 macrophages (TAMs), myeloid-derived suppressor cells (MDSCs), regulatory T (Treg) cells]. Moreover, elevated temperatures resulting in mild hyperthermia induce the synthesis and release of heat-shock proteins (HSPs), and thereby augment tumor antigenicity.
Mode of Action, Efficacy, and Safety of Radiant Warmers in Neonatology
Authors: Singer D. 
Published: May 2022

AbstractGiven the serious adverse effects of hypothermia in term and preterm infants, thermal protection is of paramount importance in neonatal care. To compare potential benefits of wIRA radiators with conventional radiant warmers in neonatology, physical investigations (agar phantoms) and clinical observations (term and preterm neonates) were performed. Physical investigations revealed a fundamental difference in the mode of action between the two types of radiation: Whereas with conventional radiant warmers, the increase in core temperature (phantoms) is preceded by marked elevations in surface temperature, wIRA leads to more direct rises in core temperature and results in smaller amounts of evaporative water loss from the surface. Clinical observations reveal that wIRA causes less skin surface warming than conventional heat irradiation at equal power densities (irradiances). wIRA used as a supplementary source of heat during primary care in the delivery room was found to exert a preventive effect against unintentional heat loss during the subsequent incubator transport of preterm neonates to the intensive care unit. Overall, due to its specific physical properties (“enhanced depth effect with less surface overheating”), wIRA seems to be particularly suited to replace the extra heat losses occurring in preterm or otherwise compromised neonates without undue risk of superficial burns.
Influence of wIRA Irradiation on Wound Healing: Focus on the Dermis
Authors: Zöller N. , Kippenberger S. 
Published: May 2022

AbstractImpaired wound healing, imbalanced fibroblast proliferation, and extracellular matrix synthesis are associated with aberrant scarring. The impact of impaired wound healing can be tremendous due to physical restrictions, high recurrence rates, stigmatization, and secondary infections in chronic wounds. It is therefore essential to develop alternative treatment regimens to those that are currently used. The highly diverse influence of water-filtered infrared-A (wIRA) on cell metabolism, bacterial colonisation, wound healing, and its high tissue penetration – reaching the subcutis without inducing harmful increases in skin surface temperature or pain – led to the investigation of the influence of the spectral and thermal component of wIRA on normal and keloid fibroblasts in vitro. Data show the potential value of the spectral and the thermal component of wIRA as an adjuvant therapy for aberrant scarring due to its differential influence on the proliferation, migration, and collagen type I synthesis of normal and keloid fibroblasts. The observed aspects in the context of hypertrophic scar treatment need to be evaluated in further basic research and clinical studies.
Whole-Body Hyperthermia in Oncology: Renaissance in the Immunotherapy Era?
Authors: Zschaeck S. , Beck M. 
Published: May 2022

AbstractA short introduction to the use of whole-body hyperthermia (WBH) in oncology is provided. The main focus is on fever-range whole-body hyperthermia (FRWBH), since various preclinical studies have shown promising results using this approach. However, FRWBH has not been comprehensively investigated in clinical oncology trials. Having provided an overview on the methods to induce WBH, we will summarize preclinical and clinical data on the mode of action of FRWBH. The latter treatment positively affects the tumor micromilieu, especially by decreasing tumor hypoxia. It has the potential to enhance tumor-directed immune reactions and has proven anti-depressive and potential analgesic effects in patients without cancer. These pleiotropic effects align with good tolerability and high acceptability by patients. Given the available evidence, we argue that FRWBH should be investigated as an adjunct to modern cancer treatments in controlled clinical trials.

The sinh-Gordon model beyond the self dual point and the freezing transition in disordered systems
Authors: Bernard Denis , LeClair André 
Published: May 2022

AbstractThe S-matrix of the well-studied sinh-Gordon model possesses a remarkable strong/weak coupling dualityb →1/b. Since there is no understanding nor evidence for such a duality based on the quantum action of the model, it should be questioned whether the properties of the model forb >1 are simply obtained by analytic continuation of the weak coupling regime 0< b <1. In this article we assert that the answer is no, and we develop a concrete and specific proposal for the properties whenb >1. Namely, we propose that in this region one needs to introduce a background chargeQ∞=b+ 1/b −2 which differs from the Liouville background charge by the shift of−2. We propose that in this regime the model has non-trivial massless renormalization group flows between two different conformal field theories. This is in contrast to the weak coupling regime which is a theory of a single massive particle. Evidence for our proposal comes from higher order beta functions. We show how our proposal correctly reproduces the freezing transitions in the multi-fractal exponents of a Dirac fermion in 2 + 1 dimensions in a random magnetic field, which provides a strong check since such transitions have several detailed features. We also point out a connection between a semi-classical version of this transition and the so-called Manning condensation phenomena in polyelectrolyte physics.

AbstractFunctional neurological disorders (FNDs) and autism spectrum disorders (ASDs) share common features in terms of deficits in emotion regulation and recognition, sensory sensitivity, proprioception and interoception. Nevertheless, few studies have assessed their overlap. We recruited 21 patients with FNDs, 30 individuals with ASDs without intellectual disabilities and 45 neurotypical adults (NA). Participants completed: the Autism Quotient (AQ); the Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R); and a questionnaire assessing functional neurological symptoms (FNS). ASDs participants also completed the Sensory Perception Quotient-Short Form (SPQ-SF35), assessing sensory sensitivity. In the FNDs sample, no patient scored above the clinical cut-off at the AQ and the 19% scored above the cut-off at the RAADS-R, a prevalence similar to the one we found in NA (15.6%; both p > 0.05). The 86.7% of participants with ASDs reported at least one FNS, a prevalence significantly higher than the NA one (35.6%, p < 0.001). In the ASDs sample, tactile hypersensitivity was found to be a risk factor for functional weakness (OR = 0.74, p = 0.033) and paraesthesia (OR = 0.753, p = 0.019). In conclusions, FNDs individuals did not present autistic traits more than NA, but ASDs individuals presented a higher number of FNSs than NA; this rate was associated with higher sensory sensitivity, especially in the touch domain.

AbstractPatients with chronic obstructive pulmonary disease (COPD) often suffer from other conditions, such as cardiovascular disease, that further increase the risk of adverse outcomes in this group. Serum homocysteine concentrations are positively associated with cardiovascular risk and have also been reported to be increased in COPD. This meta-analysis investigated the association between homocysteine concentrations and COPD. A systematic search of publications in the electronic databases PubMed, Web of Science, Scopus, and Google Scholar, from inception to September 2021, was conducted using the following terms: “Homocysteine” or “Hcy” and “Chronic Obstructive Pulmonary Disease” or “COPD”. Weighted mean differences (WMDs) were calculated to evaluate differences in homocysteine concentrations between COPD patients and non-COPD subjects. Risk of bias and certainty of evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist and GRADE, respectively. Nine studies in 432 COPD patients (mean age 65 years, 65% males) and 311 controls (mean age 65 years, 56% males) were identified. Pooled results showed that serum homocysteine concentrations were significantly higher in patients with COPD (WMD = 2.91 µmol/L, 95% CI 2.00–3.82 µmol/L;p < 0.001; high certainty of evidence). No publication bias was observed. Our results support the hypothesis that increased homocysteine concentrations are significantly associated with COPD and may account, at least in part, for the increased cardiovascular risk in these patients.
Assessing the validity of test scores using response process data from an eye-tracking study: a new approach

Published: May 2022

AbstractUnderstanding the response process used by test takers when responding to multiple-choice questions (MCQs) is particularly important in evaluating the validity of score interpretations. Previous authors have recommended eye-tracking technology as a useful approach for collecting data on the processes test taker’s use to respond to test questions. This study proposes a new method for evaluating alternative score interpretations by using eye-tracking data and machine learning. We collect eye-tracking data from 26 students responding to clinical MCQs. Analysis is performed by providing 119 eye-tracking features as input for a machine-learning model aiming to classify correct and incorrect responses. The predictive power of various combinations of features within the model is evaluated to understand how different feature interactions contribute to the predictions. The emerging eye-movement patterns indicate that incorrect responses are associated with working from the options to the stem. By contrast, correct responses are associated with working from the stem to the options, spending more time on reading the problem carefully, and a more decisive selection of a response option. The results suggest that the behaviours associated with correct responses are aligned with the real-world model used for score interpretation, while those associated with incorrect responses are not. To the best of our knowledge, this is the first study to perform data-driven, machine-learning experiments with eye-tracking data for the purpose of evaluating score interpretation validity.
Influences of atmospheric blocking on North American summer heatwaves in a changing climate: a comparison of two Canadian Earth system model large ensembles
Authors: Jeong Dae II , Cannon Alex J. , Yu Bin 
Published: May 2022

AbstractAs summer heatwaves have severe adverse impacts on human society and ecosystems, there is need to better understand their meteorological drivers and future projections under climate change. This study investigates the linkage between atmospheric blocking and summer (June–August) heatwaves over North America using two reanalysis datasets (ERA-Interim and NCEP-DOE-R2) and two large-ensembles of Canadian Earth System Models (CanESM2 and CanESM5) for the 1981–2010 baseline period as well as projected changes under high-emission scenarios out to 2071–2100. Compared to NCEP-DOE-R2, both ensembles underestimate summer blocking frequency in the north Pacific, Alaska, and western Canada (by − 37%), while CanESM2 ensemble also underestimates blocking frequency in central and eastern Canada (by − 36%). CanESM5 generally shows better performance than CanESM2 in its reproduction of blocking frequency over central and eastern Canada, which is consistent with its overall improvements in simulating large-scale climate patterns. The two ensembles, however, agree with the reanalyses in their blocking-heatwave linkages. Above-normal heatwave frequency occurs in the blocking core and its surroundings due to positive heat flux anomalies, while below-normal frequency occurs at remote locations on the eastern and/or southern flanks of the blocking core due to cold air temperature advection anomalies. Future projections in central Canada differ between the models, largely due to the significant under-representation of blocking frequency by CanESM2. However, the two ensembles generally project similar behavior between the baseline and future period for spatial distributions of blocking-heatwave linkages, indicating blocking will continue to play an important role in the development of summer heatwaves in the future.
