We argue that this illusion of understanding might become problematic (a) in physics instruction because students who have watched a misleading video might regard further teaching in school as irrelevant, and (b) learners might tend to rate videos including misconceptions better on an online platform like YouTube. Future studies should examine these two possible consequences.We investigate the short-term effects of COVID-19 on labor market flows and how they are mediated by labor market policy. Using Italian administrative data on a sample of active contracts between 2009 and the second quarter of 2020, we show that, before the pandemic, a higher share of female compared to male, young compared to old and low educated compared to high educated workers is employed in non-essential activities. When we look at the change in hirings and separations, from the 9th week of 2020 - the time when first cases and deaths due to COVID-19 were recorded -, we find a pronounced drop in hirings and endings of fixed-term contracts. Layoffs and quits increase after the 9th week, and then decline significantly, reflecting the effects of government intervention. The lifting of the lockdown triggers a slow recovery of labor market flows. Young workers, those on temporary contracts, low-educated workers, those employed in the South and those with no opportunities of working from home experience a greater decline in separation probability, indicating that government policy partly protected them from the labor market impact of the recession. The decline in the separation probability for women is lower than that for men.

Our objective was to evaluate the factors that are associated with the distress of physicians in two general hospitals in Lima, Peru. A cross-sectional correlational survey study was carried out. Physicians completed The Impact of Event Scale-Revised-22 (IES-R), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). A total of 310 physicians completed the survey, 36.5% of whom reported distress symptoms. Higher levels of distress were reached by women, by those with a prior psychiatric diagnosis, by those who considered that the hospital does not provide adequate personal protective equipment, and by those who perceived stigma from family members. Multiple regression analysis showed that there is a correlation between distress symptoms and anxiety symptoms, (B = 0.509), depressive symptoms (B = 0.305), the total hours/week worked in the Emergency Department (B=-0.142), and the stigma perception (B = 0.096). Early intervention programs must be developed to support medical staff members exposed to severe distress situations such as the current viral pandemic.The Current Opioid Misuse Measure (COMM) is a questionnaire used to identify and monitor chronic pain patients on opioid therapy who may be misusing their prescription opioids. The aim of the present study was to adapt the questionnaire for its use in Spanish-speaking populations. A total of 171 individuals (131 women and 40 men) with nononcological chronic pain participated in this cross-sectional study. The most frequent pain diagnoses in the sample were fibromyalgia, herniated disc, and rheumatoid arthritis. Systematic sampling was used. All individuals were interviewed at their clinic between March 2018 and February 2020. The dimensionality of the COMM-SV items was evaluated using an optimal implementation of parallel analysis (PA) and an exploratory factor analysis. Internal consistency, test-retest reliability, and criterion and convergent validity were calculated. The COMM-SV comprises five factors problematic interpersonal behaviour, searching for more medication than prescribed, medication misuse and self-injurious thoughts, emergency use, and memory and attention problems. It has good reliability and adequate test-retest stability. The results support its criterion and convergent validity. Given the increasing use and abuse of opioids, a valid and reliable instrument is needed in Spanish settings to identify patients with chronic pain who present aberrant behaviour related to the use of these medications. The COMM-SV enables Spanish clinicians to do that.New nurse practitioners (NPs) struggle with the transition to practice and feelings of uncertainty concerning roles and responsibilities. COVID-19 has added a new layer of stress. This pilot study used a qualitative case study design featuring semistructured interviews of 10 newly graduated primary care NPs. Data analysis revealed 2 main themes (1) emotional burden, and (2) coping and support. Emerging themes highlight the resiliency of NPs, who cope and seek support when faced with emotional burdens. This study informs educators and employers on the needs of new NPs during a global pandemic in order to better support the future workforce.Transparency has become a critical need in machine learning (ML) applications. Designing transparent ML models helps increase trust, ensure accountability, and scrutinize fairness. Some organizations may opt-out of transparency to protect individuals' privacy. Therefore, there is a great demand for transparency models that consider both privacy and security risks. Such transparency models can motivate organizations to improve their credibility by making the ML-based decision-making process comprehensible to end-users. Differential privacy (DP) provides an important technique to disclose information while protecting individual privacy. However, it has been shown that DP alone cannot prevent certain types of privacy attacks against disclosed ML models. DP with low ϵ values can provide high privacy guarantees, but may result in significantly weaker ML models in terms of accuracy. On the other hand, setting ϵ value too high may lead to successful privacy attacks. This raises the question whether we can disclose accurate transparent ML models while preserving privacy. In this paper we introduce a novel technique that complements DP to ensure model transparency and accuracy while being robust against model inversion attacks. We show that combining the proposed technique with DP provide highly transparent and accurate ML models while preserving privacy against model inversion attacks.Ginkgo biloba L. (Ginkgoaceae) is one of the best-selling products, popular in nutritional properties and health benefits. In the present study, the total phenolic compounds and flavonoid content of the ethanolic extract from G. biloba tea were also evaluated. Furthermore, the antioxidant activity was determined using DPPH assay and tyrosinase inhibitory activity was also determined with L-DOPA as a substrate. The extract showed the total phenolic compound and flavonoid content were 14.13 mg GE g-1 extract and 71.33 mg rutin equivalence g-1 DW, respectively. Taking into account the results of the DPPH, the antioxidant property at the concentration of 500 µg ml-1 was 95.29% that is similar to that of the BHT, ascorbic acid, and gallic acid used as positive controls. The inhibitory capacity of the sample against tyrosinase is lower than that of positive controls at all concentrations. The results of inhibition in terms of IC50 confirm the inhibition patterns. On the other hand, the statistical similarity of the anti-DOPA auto-oxidation (IC50) of G. biloba leaf extract and kojic acid was found (456.27 and 418.5 µg ml-1) but was lower than that of ascorbic acid (IC50 989.61 µg ml-1). A relationship was observed between the potential of antioxidant activity, tyrosinase inhibition, and anti-DOPA auto-oxidation with concentration levels of the extracts. The results of phytochemical analysis revealed the presence of tannins, flavonoids, terpenoids, and reducing sugars.
Nunavut, part of Inuit Nunangat, is a geographically vast territory in northern Canada, with a population of over 38,000 people. Most (85%) of the population identify as Inuit. Nunavut has experienced a significant rise in heterosexual infectious syphilis cases since 2012. Management of communicable diseases, including syphilis, is challenging due to high staff turnover and long delays in specimen transport times. Social determinants of health are also an important contributor. The aim of this study is to describe the epidemiology and program elements for infectious syphilis from 2012-2020 and to highlight beneficial interventions.
Syphilis is a notifiable disease in Nunavut with all cases reported to the Territorial Department of Health. Cases were staged by a medical consultant. Data were analyzed and released in public reports as part of the public health program.
From 2012 to 2020, 655 infectious syphilis cases were reported, with 53% of reported cases among females. Infection rates were highest in unity health representatives.
The rate of infectious syphilis continues to increase among females in British Columbia (BC) and Canada, raising concerns of increased incidence of congenital syphilis. We characterized syphilis cases among females in BC to identify opportunities to prevent syphilis and optimize its care.
All cases of infectious syphilis diagnosed in BC between March 13, 2018 and December 31, 2020 and reported as female gender were reviewed. Demographics, risk factors and concurrent conditions were collected from a provincial surveillance system. Subgroup analyses comparing cases with and without housing instability, substance use, mental illness and a recent sexually transmitted infection (STI) were conducted to understand differences between these subgroups. Statistical associations were calculated using chi-square or t-tests.
There were 226 reported cases of female infectious syphilis in BC during this period 38 (16.8%) in 2018; 74 (32.7%) in 2019; and 114 (50.4%) in 2020. Mean age was 32 years (range 15-75 years). Of those who reported concurrent conditions, most cases had experiences with housing instability (71.1%), substance use (68.2%) and mental illness (83.9%), while 42.9% had a recent STI. Cases who reported housing instability or substance use were significantly more likely to have experiences with a recent STI, street involvement, transactional sex, mental illness and income assistance (all
<0.01).
Our findings highlight the importance of fostering an enabling environment for syphilis care. SNS-032 price Concurrent services to support individuals with syphilis as well as housing instability, substance use and mental illness, may help prevent syphilis and improve wellbeing.

The diagnosis of this sexually transmitted disease may be missed, partly due to the painless nature of genital ulcers in its primary stage. Women in Canada are screened for syphilis in their first trimester of pregnancy, but late pregnancy testing is not done in all provinces to date; therefore, undetected vertical transmission of syphilis may occur. This case emphasizes the importance of recognizing congenital syphilis in infants and young children with unexplained growth problems and biochemical and hematological abnormalities. Congenital syphilis remains a rare diagnosis, but in the context of increased syphilis rates in Canada during recent years, clinicians should consider this diagnosis in infants presenting with compatible clinical manifestations.SNS-032 price
