Well, you’re the expert: how signals of source expertise help mitigate partisan bias

ABSTRACT Using low information rationality, citizens can compensate for their lack of political knowledge by turning to experts to help interpret and economize information. However, citizens must navigate a political media environment that is oversaturated with unqualified sources and competing cues, leading some scholars to question whether individuals are willing or able to utilize low-information rationality effectively. Much prior work focuses on partisan motivated reasoning, asserting that the influence of partisanship overwhelms that of other relevant informational cues. This is refuted by a relatively smaller subset of works, finding that the influence of partisanship is often diminished by contextual cues. I address this debate with two experimental designs that place source cues in a competing context by simultaneously manipulating expertise-related cues and partisan cues. I find that individuals do take source expertise and credibility into account, even when confronted with competing partisan source cues, helping to somewhat mitigate partisan biases.
Wild-Proso Millet (Panicum miliaceum) Control in Soybeans (Glycine max) With Postemergence Herbicides

Selective postemergence herbicides were applied broadcast to control wild-proso millet in soybeans early postemergence (early post), postemergence (post), and late postemergence (late post) when wild-proso millet was 2 to 8 cm tall, 3 to 15 cm tall, and 3 to 31 cm tall, respectively. CGA-82725, fluazifop, haloxyfop, and sethoxydim applied early post controlled 75% or less late-season wild-proso millet. Interrow cultivation following early post fluazifop applications improved wild-proso millet control and soybean yields. Higher rates of CGA-82725, haloxyfop, and sethoxydim applied post controlled 91 to 98% late-season millet, but resulting soybean yields were less than the hand-weeded check. Fenoxaprop, fluazifop, fluazifop-P, haloxyfop, quizalofop, and sethoxydim applied late post provided 93 to 99% late-season millet control and soybean yields equal to hand-weeded checks. Wild-proso millet emerging after early post or post herbicide applications contributed to reduced effectiveness from those treatments. However, most wild-proso millet emerged before late post applications and were controlled. Other herbicides including BAS-51702, clethodim, cloproxydim, and SC-1084 applied late post also controlled wild-proso millet in soybeans.
An Operation Mode Selection Method of Dual-Side Bridge Converters for Efficiency Optimization in Inductive Power Transfer

In inductive power transfer systems, impedance matching is critical in obtaining high efficiency. However, since the load impedance is subject to variations in most applications, especially wireless charging, maintaining impedance matching is a challenge. One valid solution is to maintain the equivalent load impedance at the optimal value against load variations by controlling a load-side power converter. Nonetheless, the system overall cost, size, and complexity can be increased. In this article, based on a proper selection between full-bridge and half-bridge modes of the inverter and rectifier, an operation mode selection method is proposed that can achieve semi-impedance-matching with large load variations. In general, with the proposed method, high overall efficiency can be obtained while neither additional power converters nor complicated control is required. A 1-kW prototype has been developed and the experimental results have verified the proposed method.
Analysis of the Converter Synchronizing Method for the Contribution of Battery Energy Storage Systems to Inertia Emulation

This paper presents a comprehensive analysis of the effect of the converter synchronizing methods on the contribution that Battery Energy Storage Systems (BESSs) can provide for the support of the inertial response of a power system. Solutions based on phase-locked loop (PLL) synchronization and virtual synchronous machine (VSM) synchronization without PLL are described and then compared by using time-domain simulations for an isolated microgrid (MG) case study. The simulation results showed that inertial response can be provided both with and without the use of a PLL. However, the behavior in the first moments of the inertia response differed. For the PLL-based solutions, the transient response was dominated by the low-level current controllers, which imposed fast under-damped oscillations, while the VSM systems presented a slower response resulting in a higher amount of energy exchanged and therefore a greater contribution to the support of the system inertial response. Moreover, it was demonstrated that PLL-based solutions with and without derivative components presented similar behavior, which significantly simplified the implementation of the PLL-based inertia emulation solutions. Finally, results showed that the contribution of the BESS using VSM solutions was limited by the effect of the VSM-emulated inertia parameters on the system stability, which reduced the emulated inertia margin compared to the PLL-based solutions.
New and noteworthy records of Pezizomycetes in Sweden and the Nordic countries

The class Pezizomycetes (operculate discomyce ­ tes) is relatively well known in the Nordic coun­ tries, compared to the rest of the world. Species have been collected and studied in Denmark, Norway and Finland by several mycologists dur­ ing the last 45 years (e.g. Dissing 1966, Eckblad 1968, Schumacher 1979, Dissing & Sivertsen 1983, Schumacher & Jenssen 1992, Kristiansen 2006, Harmaja 2009). In Sweden, however, no specialist has focused on this group, although Nannfeldt published a number of smaller papers (Nannfeldt 1937, 1938, 1949, 1966). Recently, in a checklist of the non­lichenized ascomycetes of Sweden, 276 Pezizomycetes species were report­ ed for the country (Eriksson 2009). Compared to the number of species recorded from the Nordic countries (i.e. Denmark, Finland, Iceland, Nor­ way and Sweden), ca 470 species (Dissing et al. 2000), many are still to be found in Sweden, considering the country’s large size and wide range of habitats. To improve the knowledge of the diversity and distribution of Pezizomycetes in Sweden, broad field­inventories were initi­ ated in 2008 under the research project “Pezi­ zomycetes in Sweden, focusing on Pezizaceae and Pyronemataceae”, funded by the Swedish Taxonomy Initiative. The fieldwork targeted ar­ eas that potentially could have a high diversity Karstenia 51: 1–16, 2011
Analysis and Prediction of False Negative Results for SARS-CoV-2 Detection with Pharyngeal Swab Specimen in COVID-19 Patients: A Retrospective Study

Background: False negative results of SARS-CoV-2 nucleic acid detection pose threats to COVID-19 patients and medical workers alike. Objective: To develop multivariate models to determine clinical characteristics that contribute to false negative results of SARS-CoV-2 nucleic acid detection, and use them to predict false negative results as well as time windows for testing positive. Design: Retrospective Cohort Study (Ethics number of Tongji Hospital: No. IRBID: TJ-20200320) Setting: A database of outpatients in Tongji Hospital (University Hospital) from 15 January 2020 to 19 February 2020. Patients: 1,324 outpatients with COVID-19 Measurements: Clinical information on CT imaging reports, blood routine tests, and clinic symptoms were collected. A multivariate logistic regression was used to explain and predict false negative testing results of SARS-CoV-2 detection. A multivariate accelerated failure model was used to analyze and predict delayed time windows for testing positive. Results: Of the 1,324 outpatients who diagnosed of COVID-19, 633 patients tested positive in their first SARS-CoV-2 nucleic acid test (47.8%), with a mean age of 51 years (SD=14.9); the rest, which had a mean age of 47 years (SD=15.4), tested negative in the first test. Ground glass opacity in a CT imaging report was associated with a lower chance of false negatives (aOR, 0.56), and reduced the length of time window for testing positive by 26%. Consolidation was associated with a higher chance of false negatives (aOR, 1.57), and extended the length of time window for testing positive by 44%. In blood routine tests, basophils (aOR, 1.28) and eosinophils (aOR, 1.29) were associated with a higher chance of false negatives, and were found to extend the time window for testing positive by 23% and 41%, respectively. Age and gender also affected the significantly. Limitation: Data were generated in a large single-center study. Conclusion: Testing outcome and positive window of SARS-CoV-2 detection for COVID-19 patients were associated with CT imaging results, blood routine tests, and clinical symptoms. Taking into account relevant information in CT imaging reports, blood routine tests, and clinical symptoms helped reduce a false negative testing outcome. The predictive AFT model, what we believe to be one of the first statistical models for predicting time window of SARS-CoV-2 detection, could help clinicians improve the accuracy and efficiency of the diagnosis, and hence, optimizes the timing of nucleic acid detection and alleviates the shortage of nucleic acid detection kits around the world.

Task conflict and extra-role performance: A cross-national perspective between East and West

Research on workplace conflict has given relatively little attention to the impact of national context on the perception toward task conflict by employees. By drawing on the conservation of resources theory, we investigate the mediating role of employee engagement between task conflict and extra-role performance in two nations: the People’s Republic of China (PRC) and the Netherlands. Results from 137 Chinese and 95 Dutch employees indicate a positive association between task conflict and extra-role performance in the PRC but a negative association in the Netherlands. Results also show that employee engagement mediates the association between task conflict and extra-role performance in both countries. We also find that relationship intensity moderates the association between task conflict and extra-role performance, through employee engagement, in both the PRC and the Netherlands. We discuss implications for theory and practice as well as offer future research directions.
The intellectual demands of the intended chemistry curriculum in Czechia, Finland, and Turkey: a comparative analysis based on the revised Bloom's taxonomy

Understanding the intellectual demands of an intended curriculum is crucial as it defines the frames for teaching and learning processes and practice during lessons. In this study, upper-secondary school chemistry curricula contents in Czechia, Finland, and Turkey were analysed, and their objectives were compared using the Revised Bloom's Taxonomy (RBT). The intellectual demands were examined analysing the action verbs in the three curricula objectives based on their association with the intended cognitive process dimensions in the RBT. The Turkish upper-secondary chemistry curriculum was found to be more structured, detailed, and containing more objectives than the Czech and Finnish curricula. The domineering objectives in cognitive demands were understand (77.2%) and analyse and apply (both 7.1%). Conceptual items dominated (59.8%) with procedural items identified (29.1%). Also, there are five metacognitive items (3.9%). The Czech curriculum, compared to the Finnish and Turkish curricula, does not take modern trends in the field of chemistry into account. The cognitive demands in the Czech curriculum were skewed toward apply (40%) with understand and evaluate accordingly represented by 20%. Conceptual items dominate with a 53.3% of occurrence. In the Finnish curriculum, the cognitive demands were skewed toward apply (47.1%) with create (23.5%) and understand (17.6%). Procedural (35.3%) domains predominate, although metacognitive objectives represent a significant share (23.5%) too. These findings from the contents and intellectual demands of the curricula in each of the three countries have the potential to help teachers and other actors in education design the interventions and assessments implemented in the classes. Comparing the distribution of intellectual demands between the countries provides an international reference for educational reforms in hand in many countries.
Variability in Yield and Yield Components of Selected Pro-vitamin A Maize (Zea mays L.) Varieties in a Humid Environment of Port Harcourt, Nigeria

This study aimed at assessing the magnitude and nature of genetic variation present in seventeen pro-vitamin A (PVA) maize varieties, investigate the extent of association among agronomic characters responsible for yield and its components in the maize varieties and evaluate the performance of the maize varieties. The field experiment was carried out at the Teaching and Research Farm of the Rivers State University, Nkpolu, Port Harcourt under rain fed conditions in May, 2018 and were laid out in a randomized complete block design with three replications. Data were collected on established plants per plot, days to 50% silking, days to 50% anthesis, anthesissilking interval, plant height, ear height, final stand count, number of ears harvested, grain moisture content, field weight and grain yield. Results showed significant differences (P < 0.01) among varieties for all traits evaluated. PVASYN-13 had the highest grain yield per hectare among other varieties. High heritability estimates coupled with high genetic advance were observed in Original Research Article Taiwo et al.; AJAHR, 5(3): 1-10, 2020; Article no.AJAHR. 55256 2 established plants per plot, anthesis-silking interval, final stand count, number of ears harvested, field weight and grain yield, an indication of the additive nature of their inheritance. Thus, the presence of variation could serve as basis for selection for yield improvement in maize.
Coalescence of lenticular anticyclones in a linearly stratified rotating fluid

This study is devoted to laboratory experiments on the coalescence of two lenticular anticyclones in a linearly stratified rotating fluid. These anticyclones are generated by injecting small volumes of fluid at the centre of a rotating tank where a linearly stratified layer was previously prepared with salt. The characteristics of the interaction between the vortices are studied by visualisation and Particle Image Velocimetry (PIV) as a function of the initial separation distance between the vortices, the Coriolis parameter of the rotating table and the Brünt-Väisälä frequency of the density stratification. Our results show that the merging critical distance depends drastically on the Rossby radius of deformation of the vortices and are in complete agreement with previous numerical modelling of vortex coalescence. We have also observed that mergers involve three-dimensional processes as the vortices intertwine together possibly because of the presence of an elliptic instability that tilts the vortex cores. They are also accompanied by the emission of vorticity filaments and internal gravity waves radiation although we cannot prove that in our experiments these waves are solely due to the merging process.
Unpopular Protest: Mass Mobilization and Attitudes to Democracy in Post-Mubarak Egypt

Political science has long debated the significance of protest during a democratic transition, but attention has been largely confined to its impact on elite support for democracy. Contributing to scholarship on the attitudinal consequences of mobilization, we examine how protest shaped popular perceptions of democracy during the post-Mubarak transition in Egypt. We do this by matching wave 2 of the Arab Barometer survey with georeferenced protest events reported in Arabic-language newspapers. Our results show that Egyptians came to hold less favorable attitudes to democracy following sustained protest in their district. We find that this relationship was principally driven by longer-lasting, static street protests that targeted public space. Qualitative case details illustrate how such tactics could disrupt everyday life and affect livelihoods. These findings highlight one way in which popular support for democracy can be eroded during a transition.
Enzymatic and Mechanical Extraction of Virgin Coconut Oil

The effect of different processing methods namely enzymatic method using crude protease extract (CPE) from overripe pineapple, microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE) methods on the recovery yield of virgin coconut oil (VCO) is evaluated. The physicochemical properties of VCOs namely color, iodine value (IV), refractive index, saponification value, moisture content, free fatty acid, p-anisidine value, lipid peroxidation, fatty acid composition, triacylglycerol (TAG) composition, melting and crystallization profile are compared. The total phenolic compounds and scavenging activity of the extracted VCOs are also examined. Results reveal that enzymatic approach exhibits the highest VCO yield (77.7% ± 0.38) at 50 °C for 2 h, followed by MAE (58.6%±0.07), control without enzyme (24.1%±0.19) and UAE (24.1%±0.12). The physicochemical properties of the VCOs extracted are found to conform to APCC standards established except IV. The antioxidant activity of VCO extracted with CPE shows no significant difference with MAE and UAE methods (p > 0.05). Lauric acid appears to be the most abundant fatty acid detected in all VCO samples. Similar exotherms and endotherms are observed in both melting and crystallization profiles with two distinct peaks exhibited. The TAG compositions of the extracted VCOs are mainly LaLaLa, LaLaM, CLaLa, CCLa, and LaMM (C = Capric acid; La = Lauric acid; M = Myristic acid).
Effect of hypothyroidism on lipid profile of type 2 diabetic patients

Background: Hypothyroidism is an endocrine disorder resulting from deficiency of thyroid hormones, and Diabetes is a metabolic disorder that share the phenotype of hyperglycaemia. Both the endocrinopathies have been found to be associated with dyslipidaemia and atherosclerosis that result into various complications. Our aim was to assess the difference of dyslipidaemia in patients suffering from hypothyroidism with diabetes as compared to diabetes alone. Methods: Study was conducted in department of medicine in SGRDIMSR, Sri Amritsar. A total of 120 patients were enrolled for the present study, the one who presented to hospital from January 2018 to August 2019 diagnosed with diabetes mellitus type 2. The patients were divided into two groups. 60 patients having type 2 diabetes without hypothyroidism (control group). 60 patients having type 2 diabetes with hypothyroidism (study group). Fasting lipid profile were performed in both the groups and were analysed for the study. Results: Dyslipidaemia was seen more in study group as compared to control group with mean cholesterol of 488.3(±144.43) and mean triglyceride levels of 354.30(±128.57) in study group as compared to control group with mean cholesterol and triglyceride levels of 179.7(±81.47) and 177.08(±118.18) with p-value of 0.001 and 0.01 respectively which were significant. Also, obesity and diabetic complication were more in patients of dual endocrinopathies as compared to diabetes alone which were also significant statistically. Conclusions: From our study it is concluded that type 2 diabetes with hypothyroidism causes more dyslipidaemia as compare to type 2 diabetes alone. So proper screening of thyroid profile of type 2 diabetic patients and its correction helps in achieving better lipidemic control which further prevent complications.
Dynamically generated momentum space shell structure of quarkyonic matter via an excluded volume model

The phase space structure of zero temperature Quarkyonic Matter is a Fermi sphere of Quark Matter, surrounded by a shell of Nucleonic Matter. We construct a quasi particle model of Quarkyonic Matter based on the constituent quark model, where the quark and nucleon masses are related by m_Q = m_N/N_c, and N_c is the number of quark colors. The region of occupied states is for quarks k_Q < k_F/N_c, and for nucleons k_F < k_N < k_F + \Delta. We first consider the general problem of Quarkyonic Matter with hard core nucleon interactions. We then specialize to a quasi-particle model where the hard core nucleon interactions are accounted for by an excluded volume. In this model, we show that the nucleonic shell forms past some critical density related to the hard core size, and for large densities becomes a thin shell. We explore the basic features of such a model, and argue this model has the semi-quantitative behaviour needed to describe neutron stars.
Vacuum Drying Kinetics of Barbunya Bean (Phaseolus vulgaris L. elipticus Mart.)

Vacuum drying characteristics of barbunya bean ( P. vulgaris L. elipticus Mart) were investigated in a laboratory scale vacuum dryer for a temperature range of 50–80 °C at constant vacuum pressure of 50 kPa. Results indicated that drying took place in the falling rate period. Six mathematical models were fitted to the experimental data; these were the Newton, Page, Henderson and Pabis, Logarithmic, Wang and Singh, and approximation of diffusion models. Comparison of the coefficient of determination (R2), root mean square error (RMSE) and reduced chi-square (2) between the observed and the predicted moisture ratios showed that the Logarithmic model gave the best results for describing single layer drying of barbunya beans. The effect of temperature on Logarithmic model constants and coefficients were also evaluated. Moisture transfer from barbunya was described by applying the Fick’s diffusion model and the effective diffusivity was calculated. Effective diffusivity increased with increasing temperature. An Arrhenius relation with an activation energy value of 14.73 kJ mol-1 expressed the effect of temperature on the diffusivity.
The effect of number of healthcare visits on study sample selection in electronic health record data

Abstract Introduction Few studies have addressed how to select a study sample when using electronic health record (EHR) data. Objective To examine how changing criterion for number of visits in EHR data required for inclusion in a study sample would impact one basic epidemiologic measure: estimates of disease period prevalence. Methods Year 2016 EHR data from three Midwestern health systems (Northwestern Medicine in Illinois, University of Iowa Health Care, and Froedtert & the Medical College of Wisconsin, all regional tertiary health care systems including hospitals and clinics) was used to examine how alternate definitions of the study sample, based on number of healthcare visits in one year, affected measures of disease period prevalence. In 2016, each of these health systems saw between 160,000 and 420,000 unique patients. Curated collections of ICD-9, ICD-10, and SNOMED codes (from CMS-approved electronic clinical quality measures) were used to define three diseases: acute myocardial infarction, asthma, and diabetic nephropathy). Results Across all health systems, increasing the minimum required number of visits to be included in the study sample monotonically increased crude period prevalence estimates. The rate at which prevalence estimates increased with number of visits varied across sites and across diseases. Conclusion In addition to providing thorough descriptions of case definitions, when using EHR data authors must carefully describe how a study sample is identified and report data for a range of sample definitions, including minimum number of visits, so that others can assess the sensitivity of reported results to sample definition in EHR data.
