Investigating partnerships and funding for the Physics Education Research community

This study will inform the Physics Education Research (PER) community about patterns of partnerships and collaborations between authors and patterns of funding sources for the PER community over the last ten years. The study involves a text-based analysis of all Physics Education Research Conference (PERC) proceedings between 2010 to 2019 to identify funding sources and to determine patterns. PERC proceedings were selected given the central role of PERC to the PER community. PERC proceedings represent the community across scope of projects from small to large, across stage of projects from beginning to finished, and across investigator experience from new to established researchers. Findings are contrasted with those from the Learning Sciences community to provide context for understanding the significance of patterns. The goal of this work is to provide insight into the community’s history and ten-year trajectory and thus enable the community to move forward in new and better directions.
Occurrence of subclinical and overt hypothyroidism among chronic kidney disease patients

Background: Chronic kidney disease (CKD) is one of the vital health problems worldwide leading to increased global morbidity and mortality. Thyroid dysfunction including hypothyroidism, hyperthyroidism and non-thyroidal illness has been reported in CKD patients. This study was conducted to determine the prevalence of subclinical and overt hypothyroidism among chronic kidney disease patients. This study also tried to correlate thyroid function abnormalities with severity of renal failure.Method: In this observational and cross sectional study, 100 patients of CKD who were admitted in Department of Medicine, Rajendra institute of medical sciences, Ranchi were studied for thyroid function abnormalities. Result: This study found that glomerular filtration rate (GFR) is positively correlated with serum T3 and T4 level (i.e. with decreasing renal function both T3 and T4 levels decreased). Serum creatinine levels were negatively correlated with serum T3 and T4 level.Conclusions: From this study it was established that CKD is associated with thyroid dysfunction characterized by low serum fT3 and fT4 with high TSH in some cases.
COVID-19 Salgınında Sağlık Çalışanlarının Kişisel Koruyucu Ekipman Kullanımları ile Depresyon, Anksiyete, Stres Düzeyleri Arasındaki İlişkinin Belirlenmesi

Aim: In our study, it was aimed to determine the relationship between the use of personal protective equipment by healthcare workers in the COVID-19 epidemic and their depression, anxiety and stress levels. Material and Methods: 384 healthcare professionals working in a pandemic hospital participated in our descriptive study conducted in May 2020. The data collection tools; A form consisting of descriptive features, personal protective equipment use cases and Depression-Anxiety-Stress Scale (DASS-21) was used. The forms were delivered to healthcare professionals online and the responses were collected and analyzed in this way. Results: In our study, the Anxiety and Stress scores of female healthcare workers and the “DASS-21 anxiety score” of single healthcare workers were found to be statistically significantly higher (p=0.008; p=0.001; p=0.019; p 0.05). During COVID-19 pandemic, statistically significant differences were found between Depression Anxiety and Stress scores of healthcare workers according to their visor or goggles / protective glasses use(p<0.01; p<0.05; p<0.01). Similarly, the use of disposable gowns / overalls and similar equipment during the epidemic caused a statistically significant difference in “DASS-21 depression and stress scores” in healthcare workers (p=0.002; p<0.01; p=0.029; p<0.05). Conclusion: It was observed that depression, anxiety and stress conditions of healthcare workersworking intensively during the COVID-19 outbreak were affected. Suitable working environments and necessary protective equipment should be provided for healthcare professionals. With the planning for the development of mental health protection programs, it can be ensured that they overcome the intensive process with the least damage.
Albomagister virgineus sp. nov., a second species of Albomagister in Europe

Albomagister virgineus is described as a new species from a collection from Hautes-Pyrénées in France. Morphological and molecular studies clearly separate it from related species of Albomagister. The assignment to Albomagister is presently suitable, however, morphological characters and a complementary morphological analysis of A. alesandrii, the only representative of the genus in Europe, contradicted the recent circumscription of this genus. Molecular results confirmed these findings and suggest heterogeneity among the Albomagister.
Bacterial resistance to oxidising biocides: an assessment of resistance mechanisms and method development

Oxidising biocides are chemical agents grouped together by a similar mechanism of action. They are used in a range of settings to remove unwanted bacterial contamination. Bacterial resistance or decreased susceptibility to biocides was first observed over 70 years ago. The majority of bacteria exist as surface attached communities known as biofilms. Biofilms have a greatly reduced susceptibility to antimicrobials including biocides compared to their planktonic counterparts. For this reason, it is important to study the effect of antimicrobials on biofilms and planktonic cells. The aim of this project is to understand the mechanisms that allow survival and tolerance of bacteria exposed to oxidising biocides by using Salmonella as a representative enteric human pathogen. A range of methods were used to investigate the response of Salmonella enterica to sodium hypochlorite, hydrogen peroxide and peracetic acid. These included culture based methods such as inactivation kinetics and MICs. Flow cytometry, Hoescht assay and GFP reporters were also used to investigate the bacterial response to biocide in the planktonic state. Confocal microscopy was undertaken to investigate the effect of biocides on the structure of biofilms and determine the distribution of survivors within biofilms. Planktonic Salmonella were found to be more susceptible than intact biofilms, but once the biofilms were dispersed this protective effect was reduced. The protective effect was also seen in Salmonella Typhimurium SL1344 which is a poor biofilm former. Hydrogen peroxide exposure resulted in a change to cellular permeability, however this was not linked to efflux through the acrAB system. Flow cytometry demonstrated differential survival upon exposure to different biocides and identified potentially viable but non-culturable populations. Confocal microscopy demonstrated non-uniform distribution of survival of cells within a biofilm. An additional observation is that bacteria responded differently to each of the three biocides tested; there is not one consistent response to biocides with oxidising activity. This research shows the importance of using appropriate methods to test biocides. A key recommendation of this study is that all biocides should be tested against biofilms. This would give a better understanding of the efficacy of the biocides in more realistic and challenging conditions.
Effect of maturity stage on quality and shelf life of tomato (lycopersicon esculentum mill) using refrigerator storage system

Tomatoes (Lycopersicon Esculentum Mill) are well known vegetable that contains vitamins, antioxidants and other health beneficial substances. This study evaluates quality (vitamin C, protein, fat, crude fibre, ash content, moisture content, carbohydrate, weight loss, firmness and antioxidant activity) and shelf- life of tomatoes under refrigerator storage method at 10oC using three maturity stages (breaking stage, pale red stage and light red stage) of ‘Beefmaster HYBRID VFNASt’ tomato varieties cultivated in a greenhouse, harvested and stored for 18 days. The physical qualities were determined during storage whilst antioxidant activity (lycopene and carotenoid concentrations) was evaluated before and after 18 days of storage. The results obtained shows that before storage; tomatoes has high moisture content (95.36%) and protein content (1.04%) at breaking stage, highest value of fat content (0.59%) and crude fibre content (1.13%) was recorded at pale red stage, while the highest ash content (0.43%), carbohydrate (3.17%), carotenoid content (0.3272 mg/g), lycopene content (0.7309 mg/g) and vitamin C content (0.1268 mg/g) was recorded at light red stage. An increase was observed in the antioxidant activities and proximate composition after 18 days of storage. The concentration of vitamin C content of tomato fruit after storage compare with the fresh sample is significantly (p<0.05) depends on maturity stages of the tomato fruit. The highest nutritional value (quality and shelf-life) was recorded for breaking stage. The results obtained also shows that carotenoid and vitamin C contents of the tomato fruits slight increase at the end of the storage period in breaking stage and this increase is significantly depends on maturity stage. It was observed that ripening stage has significant influence on the nutritional values which indicate that the ideal maturity stage to maintain optimal shelf life and nutritional quality is breaking stage of tomato fruit which is the most suitable for storage.
Evaluation of Mesoscale Convective Systems in Climate Simulations: Methodological Development and Results from MPAS-CAM over the United States

: A process-oriented approach is developed to evaluate warm-season mesoscale convective system (MCS) precipitation and their favorable large-scale meteorological patterns (FLSMPs) over the United States. This approach features a novel observation-driven MCS-tracking algorithm using infrared brightness temperature and precipitation fea- tures at 12-, 25-, and 50-km resolution and metrics to evaluate the model large-scale environment favorable for MCS initiation. The tracking algorithm successfully reproduces the observed MCS statistics from a reference 4-km radar MCS database. To demonstrate the utility of the new methodologies in evaluating MCS in climate simulations with mesoscale resolution,theprocess-orientedapproachisappliedto twoclimatesimulationsproducedbytheVariable-ResolutionModel for Prediction Across Scales coupled to the Community Atmosphere Model physics, with reﬁned horizontal grid spacing at 50 and 25km over North America. With the tracking algorithm applied to simulations and observations at equivalent resolutions, the simulated number of MCS and associated precipitation amount, frequency, and intensity are found to be consistently underestimated in the central United States, particularly from May to August. The simulated MCS precipi- tation shows little diurnal variation and lasts too long, while the MCS precipitation area is too large and its intensity is too weak. The model is able to simulate four types of observed FLSMP associated with frontal systems and low-level jets (LLJ) in spring, but the frequencies are underestimated because of low-level dry bias and weaker LLJ. Precipitation simulated under different FLSMPs peak during the daytime, in contrast to the observed nocturnal peak. Implications of these ﬁndings for future model development and diagnostics are discussed.
Surface-Response Analysis for the Optimization of a Carbon Dioxide Absorption Process Using [hmim][Tf2N]

The [hmim][Tf2N] ionic liquid is considered in this work to develop a model in Aspen Plus® capturing carbon dioxide from shifted flue gas through physical absorption. Ionic liquids are innovative and promising green solvents for the capture of carbon dioxide. As an important aspect of this research, optimization is carried out for the carbon capture system through a central composite design: simulation and statistical analysis are combined together. This leads to important results such as the identification of significant factors and their combinations. Surface plots and mathematical models are developed for capital costs, operating costs and removal of carbon dioxide. These models can be used to find optimal operating conditions maximizing the amount of captured carbon dioxide and minimizing total costs: the percentage of carbon dioxide removal is 93.7%, operating costs are 0.66 million €/tonCO2 captured (due to the high costs of ionic liquid), and capital costs are 52.2 €/tonCO2 captured.
High-contrast Hα imaging with Subaru/SCExAO + VAMPIRES

Abstract. We present the current status of Hα high-contrast imaging observations with Subaru/Subaru Coronagraphic Extreme Adaptive Optics + VAMPIRES. Our adaptive optics correction at optical wavelengths in combination with (double) spectral differential imaging (SDI) and angular differential imaging (ADI) was capable of resolving a ring feature around omi Cet and detect the Hα counterpart of jet around RY Tau. We tested the post-processing by changing the order of ADI and SDI and both of the contrast limits achieved ∼10 − 3 to 5 × 10 − 4 at 0.3″, which is comparable to other Hα high-contrast imaging instruments in the Southern Hemisphere such as very large telescope (VLT)/spectro-polarimetric high-contrast exoplanet research, VLT/MUSE, and Magellan AO. Current wavefront sensing and adaptive optics correction at optical wavelengths empirically depend on airmass, and Subaru/VAMPIRES provide great opportunities for Hα high-contrast imaging for Northern Hemisphere targets.

Review of feedback in edutainment games for preschoolers in the USA

ABSTRACT Feedback is an essential component of children’s learning; yet, how it is provided through the edutainment market for preschoolers is largely understudied. This study examined the prevalence and patterns of different types of positive and negative verbal and non-verbal feedback in 76 digital games produced by three popular US networks. Fifteen types of feedback were distinguished: nine types in response to incorrect actions and six types in response to correct actions. Although most games offered feedback, very few provided the types of feedback known to promote learning. Specifically, games relied on simple non-specific verification to indicate whether players’ actions were right or wrong and missed opportunities to use elaborative and scaffolded feedback to help players understand why an action was correct or incorrect. Additionally, games seldom missed an opportunity to provide positive feedback but often omitted negative feedback. Finally, games used repeated instructions but not positive feedback to motivate game-play. Focusing on a diversity of types of games (from math to art) available on web- and/or mobile platforms, we find a disconnect between design features associated with children’s learning and the actual design of edutainment for young children.
Peak Fitting Applied to Fourier Transform Infrared and Raman Spectroscopic Analysis of Proteins

FTIR and Raman spectroscopy are often used to investigate the secondary structure of proteins. Focus is then often laid on the different features that can be distinguished in the Amide I band (1600–1700 cm−1) and, to a lesser extent, the Amide II band (1510–1580 cm−1), signature regions for C=O stretching/N-H bending, and N-H bending/C-N stretching vibrations, respectively. Proper investigation of all hidden and overlapping features/peaks is a necessary step to achieve reliable analysis of FTIR and FT-Raman spectra of proteins. This paper discusses a method to identify, separate, and quantify the hidden peaks in the amide I band region of infrared and Raman spectra of four globular proteins in aqueous solution as well as hydrated zein and gluten proteins. The globular proteins studied, which differ widely in terms of their secondary structures, include immunoglobulin G, concanavalin A, lysozyme, and trypsin. Peak finding was done by analysis of the second derivative of the original spectra. Peak separation and quantification was achieved by curve fitting using the Voigt function. Structural data derived from the FT-Raman and FTIR analyses were compared to literature reports on protein structure. This manuscript proposes an accurate method to analyze protein secondary structure based on the amide I band in vibrational spectra.
Opposite impacts of policy and payment consequentiality treatments on willingness-to-pay in a contingent valuation study

ABSTRACT A growing number of studies investigated the effects of additional consequentiality scripts on respondents’ willingness-to-pay (WTP) and/or their beliefs in the survey arena. However, these works barely provide a clear distinction between policy and payment consequentiality, despite the possible varying effects of these two alternative beliefs. This study explored the impacts of additional policy and payment consequentiality scripts on respondents’ WTP and stated beliefs using a split-sample approach. Econometric analyses revealed that the policy and payment consequentiality scripts had significantly positive and negative impacts on respondents’ voting behaviours, respectively. Especially, the latter script was more influential than the former one. The payment consequentiality script was also found to be significantly effective in improving respondents’ stated payment consequentiality beliefs. These results suggest that emphasising payment consequentiality of a survey is important to encourage respondents to exhibit more careful attitudes towards a hypothetical scenario, thereby reducing some forms of bias in stated preference methods.
Race Differences in the Effects of Early School Behavior Problems and Substance Use Type on Lifetime Arrest

ABSTRACT Early behavior problems may correlate with adult offending. However, the relationship between early problem behavior and lifetime arrests among known offenders has received little empirical examination. In addition, few studies have explored how the associations between early problem behavior and lifetime arrests may differ among Whites and Nonwhites. It is crucial to understand how early problem behavior is associated with lifetime offending given the growing number of interventions targeting early problem behavior that has the promise to interrupt criminal careers. This study begins to explore the relationship between early problem behavior and lifetime arrests using a sample of men and women who were recently incarcerated in New Jersey. Findings suggest that early problem behavior and the usage of various drugs impact lifetime arrests; however, these factors differ between Whites and Nonwhites. Policy implications, limitations, and directions for future research are discussed.
Application of FTA® Cards for detection and storage of avian influenza virus

Abstract Introduction: The aim of the study was to test the utility of Flinders Technology Associates filter paper (FTA® Cards) for molecular detection and storage of avian influenza virus (AIV). Material and Methods: There were two strains of AIV used in the study: low pathogenicity H7N1 and high pathogenicity H5N1 subtypes. Detection of viral material was conducted using molecular RT-PCR and rRT- PCR method. Results: The infectivity of LPAIV/H7N1 and HPAIV/H5N1 was completely inactivated within 1 h and 24 h after adsorption to FTA® Cards at room temperature, respectively. Viruses stored on FTA® Cards had detection limit approximately 1 log10 lower than live viruses. Viral RNA of both strains were detectable on the cards by rRT-PCR for a minimum of 150 d, irrespectively of storage temperatures (room temperature, -20ºC). RNA was also detected in all samples obtained from SPF chickens experimentally infected with HPAI/H5N1 on 3rd and 4th day post-infection (p.i.). Conclusion: FTA® Cards enable safe and effective alternative transport of samples for molecular diagnosis of AIV.
