Full textAbstract:
Preclass reading quizzes (RQs) have been shown to enhance student performance. Many instructors implementing evidence-based teaching assign preclass RQs to ensure their students are prepared to engage in class activities. Textbook companies now offer a gamified, adaptive-learning RQ format. In these RQs, students answer point-valued questions until they reach a threshold. If students answer incorrectly, the question decreases in point value on the next attempt. These RQs also give students who answer questions incorrectly more questions on that topic and direct students to sections of a textbook they need to review. We assessed the impact of gamified, adaptive preclass RQs compared with more traditional preclass RQs on in-class RQs and course exam performance as well as students’ perceptions of RQs. Students in the gamified, adaptive treatment performed equally compared with students in the traditional, static treatment on in-class RQs and course exams. While students in the gamified, adaptive treatment did have a more positive perception of preclass RQs, this factor explained less than 3% of the variation in RQ perception. Our findings suggest that instructors should verify that gamified, adaptive technologies impact student learning in their course before integrating them into their course and asking students to pay for them.

Full textAbstract:
Abstract Rhetorical questions (RQs), as a cross-breed of questions and statements, represent an effective tool in putting forward the Speaker’s ideas, as well as influencing the ideas and opinions of other people. Because of their communicative effectiveness and multifunctionality, they are frequently used in different contexts and for different purposes, and, as such, they represent an interesting topic for further research. The aim of this paper is threefold: (i) to explore the nature of the implied answer to RQs, (ii) to offer a classification of RQs based on the Speaker’s communication style, and (iii) to examine whether (or to what extent) the Speaker-Addressee relationship (peer-to-peer, superior-to-inferior, inferior-to-superior) influences the selection and frequency of use of different types of RQs. Using Stalnaker’s (2002) model of Common Ground and Caponigro and Sprouse’s (2007) concepts of Speaker’s and Addressee’s Beliefs, the author redefines the nature of the answers implied by RQs, claiming that they are imposed on the Addressee rather than mutually recognized as obvious. Based on the model of communication styles as defined by Yuan et al. (2018), RQs are classified into aggressive, friendly and sarcastic/ironical questions with imposed answers. The analysis of the corpus, which consisted of 275 RQs taken from ten American movie scripts, showed that friendly RQs are more common than the other two types, and that, in instances where one of the interlocutors is in a superior position, superior-to-inferior RQs are by far more common than vice versa. The finding that RQs asked by inferiors make up less than a third of RQs occurring between interlocutors with different social standing is in line with the view that answers to RQs are imposed on Addressees.

Full textAbstract:
The paper examines whether rhetorical questions (RQs) with insulting content or implications soften or intensify the insulting content that they express, as compared to corresponding direct statements with similar insulting content. The analysis is based on the results of two online surveys conducted among 276 Bosnian university students (182 and 94, respectively), who evaluated, in regard to their offensiveness, two sets of RQs and corresponding statements with insulting content or implications. Three types of insulting RQs were included in the surveys: insulting RQs without explicitly offensive terms, insulting RQs that incorporate derogatory words, and sarcastic RQs with insulting implications. The expected results were that: a) in line with Frank’s (1990) account of strengthening effects of RQs as their primary function, insulting RQs, with or without derogatory words, will function as amplifiers, and sound more offensive than corresponding declaratives; and b) sarcastic RQs, following Dews and Winner’s (1995) account of softening effects of sarcastic utterances, will function as mitigators, as compared to non-sarcastic declaratives with insulting content. The obtained results indicate that the first hypothesis cannot be verified (in spite of some indications that slight amplifying effects do exist), and the second hypothesis is completely rejected, with some likelihood that the opposite could be true.

Full textAbstract:
This study aimed to explore the impact of the pandemic on medical students’ mental health in Italy using a repeated cross-sectional survey with a nested longitudinal subsample (first timepoint: 2018; second: 2020/2021). Three research questions (RQs) were investigated. Study 1 (longitudinal sub-sample) explored whether medical students had higher levels of depressive symptoms and stress during the pandemic compared with a pre-pandemic period (RQ1) and what variables were associated with these conditions during the pandemic adjusting for baseline levels (RQ2). Study 2 (repeated cross-sectional data) aimed to examine whether medical students had higher levels of these conditions during the pandemic compared with their same-year peers during a pre-pandemic period (RQ3). In Study 1, higher levels of depressive symptoms and stress were shown during the pandemic (RQ1). Multivariable models highlighted associations between poor mental health and worsening of the judgment of medical school choice, worsened psychological condition due to the pandemic, economic repercussions due to the pandemic, and baseline levels of symptoms (RQ2). In Study 2, our findings reported higher levels of depressive symptoms and stress during the pandemic, also adjusting for other variables (RQ3). In conclusion, depressive symptoms and stress were greater during the pandemic. The most relevant variables were pandemic-related items and medical school choice judgment.

Full textAbstract:
This paper reports on the prosody of rhetorical questions (RQs) and information-seeking questions (ISQs) in German for two question types—polar questions and constituent questions (henceforth “ wh-questions”). The results are as follows: Phonologically, polar RQs were mainly realized with H-% (high plateau), while polar ISQs mostly ended in H-^H% (high-rise). Wh-RQs almost exclusively terminated in a low edge tone, whereas wh-ISQs allowed for more tonal variation (L-%, L-H%, H-^H%). Irrespective of question type, RQs were mainly produced with L*+H accents. Phonetically, RQs were more often realized with breathy voice quality than ISQs, in particular in the beginning of the interrogative. Furthermore, they were produced with longer constituent durations than ISQs, in particular at the end of the interrogative. While the difference between RQs and ISQs is reflected in the intonational terminus of the utterance, this does not happen in the way suggested in the semantic literature, and in addition, accent type and phonetic parameters also play a role. Crucially, a simple distinction between rising and falling intonation is insufficient to capture the realization of the different illocution types (RQs, ISQs), against frequent claims in the semantic and pragmatic literature. We suggest alternative ways to interpret the findings.

Full textAbstract:
Abstract Although aging in the community promotes well-being in older adults, contextual factors (e.g., housing cost burden, neighborhood cohesion, neighborhood disorder) may impact this relationship. Identifying such risk factors represents a first step toward improving older adult well-being. NHATS data (Rounds 5–8) were used to answer two research questions (RQs). RQ1: “Is housing cost burden significantly associated with well-being?” RQ2: “Is this association further moderated by neighborhood cohesion and neighborhood disorder?” Participants were 18,311 adults ≥ 65 years old. Well-being was assessed by summing 11 commonly identified indicators. Two items were merged to assess housing cost burden (categories: “no burden,” “no money for utilities,” “no money for rent,” and “no money for utilities or rent”). Neighborhood cohesion and disorder were combined (categories: “no cohesion, no disorder,” “yes cohesion, no disorder,” “no cohesion, yes disorder,” and “yes cohesion, yes disorder”). Both RQs were assessed through a random coefficient model controlling for established covariates. RQ1 results revealed that, compared to “no burden,” “no money for utilities or rent” (B = −1.22, p = .003) and “no money for rent” (B = −1.50, p = .007) were significantly associated with well-being. RQ2 results revealed that “no cohesion, no disorder” significantly moderated the association between “no money for utilities or rent” and well-being (B = −2.44, p = .011). These results indicate that increased housing cost burden is associated with decreased well-being, especially for those reporting no neighborhood cohesion. Future research should examine neighborhood-level protective factors promoting cohesion for older adults to support well-being.

Full textAbstract:
Abstract The article explores German discourse particles (DiPs) in rhetorical wh-questions (wh-RQs). While schon (roughly ‘unexpectedly’) only marks rhetorical wh-questions, denn (roughly ‘I wonder’) marks contextually arising information-seeking or rhetorical Questions under Discussion (QuDs), with or without schon. Since ja (roughly ‘unquestionably’) marks shared information, it is incompatible with questions by itself, but occasionally occurs in wh-RQs left of DiPs like schon instead of denn. The results of two acceptability judgment experiments confirm that ja is strongly dispreferred in RQs, the presence of schon improves RQs with and without ja, and denn has no effect on acceptability. A follow-up study further indicated the rhetorical reading of our target questions to prevail independently from DiPs. We conclude that ja in RQs operates on the information contributed by elements like schon, denoting roughly that the issue in question arises ‘unquestionably against expectations’. Our contexts were neutral regarding the discourse functions of ja and denn (side remarks vs. QuDs), unlike the contexts of the findings, from which we deduce that the marked ja schon-RQs, while grammatical, require specific felicity conditions. A first attempt to confirm this experimentally was globally unsuccessful and could only reveal potential hints in an exploratory analysis.

Full textAbstract:
Background: Reproducibility and generalization are major challenges for clinically significant prostate cancer modeling using MRI radiomics. Multicenter data seem indispensable to deal with these challenges, but the quality of such studies is currently unknown. The aim of this study was to systematically review the quality of multicenter studies on MRI radiomics for diagnosing clinically significant PCa. Methods: This systematic review followed the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Multicenter studies investigating the value of MRI radiomics for the diagnosis of clinically significant prostate cancer were included. Quality was assessed using the checklist for artificial intelligence in medical imaging (CLAIM) and the radiomics quality score (RQS). CLAIM consisted of 42 equally important items referencing different elements of good practice AI in medical imaging. RQS consisted of 36 points awarded over 16 items related to good practice radiomics. Final CLAIM and RQS scores were percentage-based, allowing for a total quality score consisting of the average of CLAIM and RQS. Results: Four studies were included. The average total CLAIM score was 74.6% and the average RQS was 52.8%. The corresponding average total quality score (CLAIM + RQS) was 63.7%. Conclusions: A very small number of multicenter radiomics PCa classification studies have been performed with the existing studies being of bad or average quality. Good multicenter studies might increase by encouraging preferably prospective data sharing and paying extra care to documentation in regards to reproducibility and clinical utility.

Full textAbstract:
This article contributes to our knowledge about the prosodic realisation of rhetorical questions (RQs) as compared to information-seeking questions (ISQs). It reports on a production experiment testing the prosody of English wh- and polar RQs and ISQs in a Canadian variety. In previous literature, the contribution of prosody to the distinction between the two illocution types has often been limited to the intonational realisation of the terminus of the utterance, i.e. whether it ends in a rise or a fall. Along with edge tones, we tested other phonological and phonetic parameters. Our results are as follows: (i) The intonational terminus was distinctive only for polar questions (rise vs plateau), not for wh-questions (low throughout). (ii) Moreover, the semantic difference between RQs and ISQs is signalled by pitch accents. It is reflected in nuclear pitch accent type for wh-questions, and accent type and position for polar questions. (iii) Phonetically, RQs are produced with longer constituent durations and – for wh-questions – a softer voice quality in the wh-word. Taken together, several intonational categories and phonetic parameters contribute to the distinction between RQs and ISQs. A simple distinction between rising and falling intonation is in any case insufficient.

Background. Radiation-induced toxicity represents a crucial concern in oncological treatments of patients affected by head and neck neoplasms, due to its impact on survivors’ quality of life. Published reports suggested the potential of radiomics combined with machine learning methods in the prediction and assessment of radiation-induced toxicities, supporting a tailored radiation treatment management. In this paper, we present an update of the current knowledge concerning these modern approaches. Materials and Methods. A systematic review according to PICO-PRISMA methodology was conducted in MEDLINE/PubMed and EMBASE databases until June 2019. Studies assessing the use of radiomics combined with machine learning in predicting radiation-induced toxicity in head and neck cancer patients were specifically included. Four authors (two independently and two in concordance) assessed the methodological quality of the included studies using the Radiomic Quality Score (RQS). The overall score for each analyzed study was obtained by the sum of the single RQS items; the average and standard deviation values of the authors’ RQS were calculated and reported. Results. Eight included papers, presenting data on parotid glands, cochlea, masticatory muscles, and white brain matter, were specifically analyzed in this review. Only one study had an average RQS was ≤ 30% (50%), while 3 studies obtained a RQS almost ≤ 25%. Potential variability in the interpretations of specific RQS items could have influenced the inter-rater agreement in specific cases. Conclusions. Published radiomic studies provide encouraging but still limited and preliminary data that require further validation to improve the decision-making processes in preventing and managing radiation-induced toxicities.
