Relation of corona-specific health literacy to use of and trust in information sources during the COVID-19 pandemic

Background COVID-19 has developed into a worldwide pandemic which was accompanied by an «infodemic» consisting of much false and misleading information. To cope with these new challenges, health literacy plays an essential role. The aim of this paper is to present the findings of a trend study in Switzerland on corona-specific health literacy, the use of and trust in information sources during the COVID-19 pandemic, and their relationships. Methods Three online surveys each with approximately 1′020 individuals living in the German-speaking part of Switzerland (age ≥ 18 years) were conducted at different timepoints during the COVID-19 pandemic, namely spring, fall and winter 2020. For the assessment of corona-specific health literacy, a specifically developed instrument (HLS-COVID-Q22) was used. Descriptive, bivariate, and multivariate data analyses have been conducted. Results In general, a majority of the Swiss-German population reported sufficient corona-specific health literacy levels which increased during the pandemic: 54.6% participants in spring, 62.4% in fall and 63.3% in winter 2020 had sufficient corona-specific health literacy. Greatest difficulties concerned the appraisal of health information on the coronavirus. The most used information sources were television (used by 73.3% in spring, 70% in fall and 72.3% in winter) and the internet (used by 64.1, 64.8 and 66.5%). Although health professionals, health authorities and the info-hotline were rarely mentioned as sources for information on the coronavirus, respondents had greatest trust in them. On the other hand, social media were considered as the least trustworthy information sources. Respondents generally reporting more trust in the various information sources, tended to have higher corona-specific health literacy levels. Conclusions Sufficient health literacy is an essential prerequisite for finding, understanding, appraising, and applying health recommendations, particularly in a situation where there is a rapid spread of a huge amount of information. The population should be supported in their capability in appraising the received information and in assessing the trustworthiness of different information sources.

New Technologies in Second Language Signed Assessment

In this chapter, two signed language technologies are introduced: signed language recognition and signed language synthesis/animation. The modality-specific challenges of these technologies are discussed, originating in the multichannel nature of signs and the lack of a standardized writing system. The state of research of each technology is outlined, demonstrating that the existing body of research is considerably smaller than that of the field of automatic spoken language processing. The chapter describes the combination of the two signed language technologies in real-world applications. Most importantly, it explores the potential application of each technology to second language (L2) signed language assessment. Finally, an example of an existing use case is given: the application of signed language recognition to a vocabulary test for adult L2 learners of Swiss German Sign Language.

Phonological Complexity: Bernese Swiss German in Ohio and Misiones

This article investigates the notion of complexity as it applies to two phonological characteristics of Heritage Bernese Swiss German, namely /l/-vocalization and /nd/-velarization. We survey literature on the role of complexity in language change generally, as well as how it applies to heritage languages specifically. We then present findings from our study of two groups of Heritage Bernese speakers, one in the United States and one in Argentina, with additional reference to the local contact languages. Our findings suggest that the loss of /nd/-velarization in Misiones, Argentina is most likely the result of an internally-driven reduction of complexity. For both the Ohio and Misiones communities, however, /l/-vocalization has been maintained. We conclude by discussing the importance of research into language dyads beyond those in the United States as well as pursuing research on lesser-studied heritage languages.

Internal morphology of 101 mandibular canines of a Swiss-German population by means of micro-CT: An ex vivo study

The aim of this study was to investigate the root canal system morphology by means of a root canal configuration (RCC) classification described with a four-digit system, the physiological foramen geometry and accessory canal frequency and morphology, of 101 mandibular canines (MaCa) of a Swiss-German population by means of micro-computed tomography. Micro-CT examination of the MaCa was performed and the obtained images analyzed with a 3D imaging software. In single-rooted MaCas, the most frequently observed RCCs were 1-1-1/1 (74.5%) and 1-1-1/2 (14.3%). Seven other RCCs were less frequently observed with a frequency from 4.1 to 1.0%. One physiological foramen was observed in 80.6% of the MaCas, two in 16.3%, three in 1.0% and four in 2.0%. Accessory and connecting canals were apparent only in the middle and apical root thirds. Two-rooted MaCas occurred less frequently (n = 3). When one physiological foramen was present, the mean size of the narrow and wide diameters were 0.28 mm (± 0.07) and 0.40 mm (± 0.11), while the distance between physiological and anatomical foramen was 0.45 mm (± 0.17). MaCas are predominantly single-rooted teeth with a 1-1-1/1 or 1-1-1/2 RCC. Most MaCas had one physiological foramen with an oval shape.

Who Loses Motivation and Who Keeps it up? Investigating Student and Teacher Factors for Students’ Motivational Development Across Multiple Subjects

This longitudinal person-centered study investigated the combined role of student (gender, personality, choice of elective major subject) and teacher factors (perceived autonomy support, competence support, social relatedness) in explaining stability and change in profiles of extrinsic and intrinsic value beliefs in Mathematics, German, English, and French across Grades 9 to 11. In N = 850 (54% female, Grade 9: Mage = 15.6 years) Swiss-German upper-secondary school students, multilevel latent transition analyses revealed four rather subject-independent student profiles of extrinsic value beliefs across the four subjects, and five more subject-specific profiles of intrinsic value beliefs. Transitions into profiles with lower extrinsic value beliefs depended mostly on stable student factors such as their gender, elective major subject, and conscientiousness, whereas changes in intrinsic value beliefs depended mostly on students’ year-specific perceived need satisfaction in Mathematics and French. We discuss implications for the prevention of motivational decline.

Exploring systematic orthographic crosslinguistic similarities to enhance foreign language vocabulary learning

This study explores whether middle-school students can exploit explicitly addressed crosslinguistic lexical similarities between German and English to learn vocabulary more efficiently. Across six weeks, 260 Swiss German learners of English as a foreign language (17 classes) completed three vocabulary learning tests (T1, T2 and T3). Additionally, 7 of these 17 classes attended a 90-minute intervention between the first and second test: During a 45-minute introductory lesson students discovered four systematic orthographic correspondence rules (e.g. <p> to <f> as in ship and Schiff), followed by three 15-minute sessions to consolidate their knowledge. The intervention group’s improvement in cognate learning was significantly larger in comparison to the control group. The difference was observed across both test modes and all rules introduced. While learners’ initial English vocabulary size correlated with their overall performance, it did not affect intervention uptake. This suggests that these younger learners benefitted from form-focused instruction, independent of proficiency and type of correspondence.

High regional variation in prostate surgery for benign prostatic hyperplasia in Switzerland

Background Among various treatment options for benign prostatic hyperplasia (BPH), surgical therapy is the most invasive. As Switzerland has the highest transurethral prostatectomy rate among OECD countries, we assessed the regional variation in prostate surgery for BPH and explored potential determinants of variation. Methods We conducted a population-based analysis using discharge data for men aged ≥40 years with transurethral or simple prostatectomy from all Swiss hospitals during 2013–2018. After excluding patients with genitourinary/prostate cancer, we derived hospital service areas (HSAs) by analyzing patient flows. We calculated age-standardized mean procedure rates and variation indices (extremal quotient [EQ] and systematic component of variation [SCV]). We estimated the reduction in variance across HSAs of prostatectomy rates in multilevel regression models, with incremental adjustment for age, regional cultural and socioeconomic factors, disease burden, density of urologists, and the time since urologists’ graduation. Results Overall, 44,253 prostatectomies (42,710 transurethral and 1543 simple) from 44 HSAs were analyzed. The mean age-standardized prostate surgery rate was 314 (range 166–500) per 100,000 men aged ≥40 years per year. The EQ was 3.01 and the SCV 5.53, indicating a high regional variation. In multivariate models, men aged 75–79 years had an 11.6-fold higher prostatectomy rate than those aged 50–54 years. French/Italian language areas had a 21% lower rate than Swiss German speaking areas. Socioeconomic factors, disease burden, and density of urologist/time since graduation were not associated with prostatectomy rates. After full adjustment, 80% of the variance in prostate surgery across HSAs remained unexplained. Conclusion We found a remarkably high regional variation in prostate surgery rates for BPH within Switzerland.
