Health websites on COVID-19: are they readable and credible enough to help public self-care?

Objective:There are concerns about nonscientific and/or unclear information on the coronavirus disease 2019 (COVID-19) that is available on the Internet. Furthermore, people''s ability to understand health information varies and depends on their skills in reading and interpreting information. This study aims to evaluate the readability and creditability of websites with COVID-19-related information.Methods:The search terms “coronavirus,” “COVID,” and “COVID-19” were input into Google. The websites of the first thirty results for each search term were evaluated in terms of their credibility and readability using the Health On the Net Foundation code of conduct (HONcode) and Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), Gunning Fog, and Flesch Reading Ease Score (FRE) scales, respectively.Results:The readability of COVID-19-related health information on websites was suitable for high school graduates or college students and, thus, was far above the recommended readability level. Most websites that were examined (87.2%) had not been officially certified by HONcode. There was no significant difference in the readability scores of websites with and without HONcode certification.Conclusion:These results suggest that organizations should improve the readability of their websites and provide information that more people can understand. This could lead to greater health literacy, less health anxiety, and the provision of better preventive information about the disease.

Passion and Preparation in the Basic Course: The Influence of Students' Ego-Involvement with Speech Topics and Preparation Time on Public-Speaking Grades

Abstract

Authors of basic public-speaking course textbooks frequently encourage students to select speech topics in which they have vested interest, care deeply about, and hold strong opinions and beliefs. This study explores students' level of ego-involvement with informative and persuasive speech topics, examines possible ego-involvement predictors of students' speech grades, and investigates the influence of preparation time and process activities on public-speaking grades. Results reveal that students' ego-involvement is positively related to their speech success; however, the explanation is more complex than those offered by basic public-speaking course textbooks. Pedagogical implications and areas for future research are discussed.     

Readability and acceptance of public relations releases from institutions of higher education

This study compared readability levels for PR releases used and not used by newspapers to determine if they differ in reading difficulty. Flesch scores and other readability measures were calculated. Releases used were easier to read. However, releases with longer paragraphs were more acceptable with shorter paragraphs.

Dargah libraries in India: a comparative study

This paper relates to the difficulty in retrieving precise information from big repositories of magazine articles in full text, and proposes an Extended Markup Language (XML) vocabulary for improving retrieval rates. The hypothesis tested was as follows: Magazine articles marked up with an XML vocabulary, indexed only by selected parts, give more precise search results than the same search using full text index.

The study was exploratory with the following characteristics: 29 magazine articles were tested for results, 8 scholars were interviewed for defining 23 search strategies and evaluating results. The data showed that precision improved from 40.72% with full text search to 62.84% using XML markup and searching only in specific labels.

Revision of the vocabulary and more testing has to be done by the library and information science community in order to obtain a valid vocabulary and provide more research results. Cultural characteristics and politics of librarians and information managers’ community are as important as technical issues in order to consider any technical proposal to be implemented successfully to achieve interoperability.     

Families Are Learning in Science Museums

This report is based on research findings of a National Science Foundation (NSF)-funded study conducted by the Philadelphia/Camden Informal Science Education Collaborative (PISEC), which consists of four institutions: The Franklin Institute Science Museum, the New Jersey State Aquarium, The Academy of Natural Sciences, and the Philadelphia Zoological Garden. The first year's study addressed the question “How can we identify and measure family learning in science museums?” It documented a relationship between learning levels and observable behaviors. On the basis of coding family conversations and interview data for level of learning, we see that families do learn from exhibits and that the level of learning is related to specific observed behaviors. Grouping these behaviors as performance indicators provides a useful measure of exhibit learning.     

A health literacy analysis of the consumer-oriented COVID-19 information produced by ten state health departments

Objective:The COVID-19 pandemic highlights the public''s need for quality health information that is understandable. This study aimed to identify (1) the extent to which COVID-19 messaging by state public health departments is understandable, actionable, and clear; (2) whether materials produced by public health departments are easily readable; (3) relationships between material type and understandability, actionability, clarity, and reading grade level; and (4) potential strategies to improve public health messaging around COVID-19.Methods:Based on US Centers for Disease Control and Prevention statistics from June 30, 2020, we identified the ten states with the most COVID-19 cases and selected forty-two materials (i.e., webpages, infographics, and videos) related to COVID-19 prevention according to predefined eligibility criteria. We applied three validated health literacy tools (i.e., Patient Education Materials Assessment Tool, CDC Clear Communication Index, and Flesch-Kincaid Grade Level) to assess material understandability, actionability, clarity, and readability. We also analyzed correlations between scores on the three health literacy tools and material types.Results:Overall, COVID-19 materials had high understandability and actionability but could be improved in terms of clarity and readability. Material type was significantly correlated with understandability, actionability, and clarity. Infographics and videos received higher scores on all tools.Conclusions:Based on our findings, we recommend public health entities apply a combination of these tools when developing health information materials to improve their understandability, actionability, and clarity. We also recommend using infographics and videos when possible, taking a human-centered approach to information design, and providing multiple modes and platforms for information delivery.     

Reforming social studies: Implications for curriculum and textbooks

The present role of textbooks in the social studies is reviewed, and recent experiences in California provide a case study illustrating the reform process. The future of textbooks and their reform is discussed, including the place of technology, new roles for textbooks, possibilities for their improvement, and the importance of extending reform beyond textbooks into teaching and school governance. David L. Elliott is director of Educational Materials Associates, consultants in textbook research, staff development, and curriculum improvement. With Arthur Woodward, he is the coeditor ofTextbooks and Schooling in the United States, the 89th Yearbook of the National Society for the Study of Education.     

Readability: A Factor in Student Research?

Readability assessments of works cited in freshmen informative and argumentative speeches were performed with the Flesch-Kincaid Reading Grade Level and Flesch Reading Ease assessment tools available in Microsoft Word. Students selected their sources independently, and their sources were grouped as journals, magazines and newspapers, and websites, which were then subdivided by domain type. The wide range of readability scores in sources cited in freshman speeches raises questions related to college freshmen's reading abilities and how that affects student's selection of sources when performing research for class assignments.     

In a different mode: Masculine styles of communicating closeness

A number of contributors to Journal of Applied Communication Research have demonstrated communication research and theory can inform practical conduct in sundry situations. Less addressed has been the pragmatic potential of research to reform its own practice. Believing research is ideally self‐reflexive, we apply principles of scholarly inquiry to evaluate knowledge about gender and communication in close relationships. We document a prevalent bias that favors feminine styles of relating, characterized by verbal, emotional disclosure, and that devalues activity‐focused modes empirically more associated with masculinity. We then trace the presence of this bias in textbooks on gender and communication and interpersonal relationships, and we suggest teaching that relies on a non‐inclusive model of intimacy may misguide students’ communicative expectations and interpretations and may misdirect practical conduct in friendships and romantic relationships. Finally, we return to existing scholarship to extract information about masculine styles of experiencing and expressing closeness as a starting point for more inclusive research and teaching about gender, communication and human relationships.     

A multilevel meta-analysis of studies reporting correlations between the h index and 37 different h index variants

This paper presents the first meta-analysis of studies that computed correlations between the h index and variants of the h index (such as the g index; in total 37 different variants) that have been proposed and discussed in the literature. A high correlation between the h index and its variants would indicate that the h index variants hardly provide added information to the h index. This meta-analysis included 135 correlation coefficients from 32 studies. The studies were based on a total sample size of N = 9005; on average, each study had a sample size of n = 257. The results of a three-level cross-classified mixed-effects meta-analysis show a high correlation between the h index and its variants: Depending on the model, the mean correlation coefficient varies between .8 and .9. This means that there is redundancy between most of the h index variants and the h index. There is a statistically significant study-to-study variation of the correlation coefficients in the information they yield. The lowest correlation coefficients with the h index are found for the h index variants MII and m index. Hence, these h index variants make a non-redundant contribution to the h index.     

Scoring research output using statistical quantile plotting

In this paper, we propose two methods for scoring scientific output based on statistical quantile plotting. First, a rescaling of journal impact factors for scoring scientific output on a macro level is proposed. It is based on normal quantile plotting which allows to transform impact data over several subject categories to a standardized distribution. This can be used in comparing scientific output of larger entities such as departments working in quite different areas of research. Next, as an alternative to the Hirsch index [Hirsch, J.E. (2005). An index to quantify an individuals scientific research output. Proceedings of the National Academy of Sciences of the United States of America, 102(46), 16569–16572], the extreme value index is proposed as an indicator for assessment of the research performance of individual scientists. In case of Lotkaian–Zipf–Pareto behaviour of citation counts of an individual, the extreme value index can be interpreted as the slope in a Pareto–Zipf quantile plot. This index, in contrast to the Hirsch index, is not influenced by the number of publications but stresses the decay of the statistical tail of citation counts. It appears to be much less sensitive to the science field than the Hirsch index.

Objectives: By completing this activity, students should be able to (1) describe the principles of CCP, (2) examine critically how race and gender are represented in communication textbooks, and (3) identify how textbooks reproduce and reflect dominant assumptions about the study of communication, race, and gender.     

Technological research in the EU is less efficient than the world average. EU research policy risks Europeans’ future

We have studied the efficiency of research in the EU by a percentile-based citation approach that analyzes the distribution of country papers among the world papers. Going up in the citation scale, the frequency of papers from efficient countries increases while the frequency from inefficient countries decreases. In the percentile-based approach, this trend, which is uniform at any citation level, is measured by the e_p index that equals the P_{top 1%}/P_{top 10%} ratio. By using the e_p index we demonstrate that EU research on fast-evolving technological topics is less efficient than the world average and that the EU is far from being able to compete with the most advanced countries. The e_p index also shows that the USA is well ahead of the EU in both fast- and slow-evolving technologies, which suggests that the advantage of the USA over the EU in innovation is due to low research efficiency in the EU. In accord with some previous studies, our results show that the European Commission’s ongoing claims about the excellence of EU research are based on a wrong diagnosis. The EU must focus its research policy on the improvement of its inefficient research. Otherwise, the future of Europeans is at risk.     

Anger,fear, uncertainty,and attitudes: a test of the cognitive-functional model

The cognitive-functional model of discrete negative emotions and attitude change (CFM; Nabi, 1999) attempts to bridge the theoretical gap between “emotional” and “rational” approaches to persuasion by focusing on how emotions motivate attention to and processing of persuasive messages. As a first test of the CFM, this study explored the effects of 2 emotions, anger and fear, and 2 levels of expectation of message reassurance, certainty and uncertainty, on attitudes toward domestic terrorism legislation. Results supported a main effect for emotion type, suggesting that anger promotes deeper information processing than fear, and a main effect for reassurance certainty level, with uncertainty promoting deeper information processing. The expected interaction between emotion type and reassurance expectation level was not found. Implications of these findings for the model and persuasion research generally are discussed.     

Disposition versus situation: Neurocommunlcology and the influence of trait apprehension versus situational factors on state public speaking anxiety

Research indicates that individuals with elevated levels of public speaking anxiety report significantly different mental representations of the public speaking context, when compared to individuals with lower levels of anxiety. To examine the effect of the differences in mental representations, narratives for three public speaking contexts were developed. Results indicated that disposition (i.e., trait apprehension) was a better predictor of state anxiety when giving an impromptu speech. Situational factors (i.e., importance, skills, impression), however, were better predictors of state anxiety when either giving a speech to a 5^th grade class or giving a speech to friends.     

Lighting the Shroud of Turin for Exhibition in 2015

ABSTRACT

Lighting a cultural heritage artifact requires balancing visual perception with preventive conservation, by providing the best lighting (in terms of spectral distribution and quantity) to enable the viewer to appreciate details and color, while limiting photo-induced degradation. The paper outlines the methodology applied by a multi-disciplinary team while lighting the Shroud of Turin at its last public exhibition in 2015. The methodology considered the special requirements of the Shroud, including exposure to ultraviolet light, while providing appropriate display conditions that would meet audience expectations. The desired appearance (readability of the body image and color) was defined with the help of Shroud researchers and confirmed by subjective tests, while appropriate light levels for preservation were set in agreement with standard requirements and using knowledge of the degradation of linen in visible and UV light. The installation provided a controlled environment and a managed visitor route to the Shroud, assuring excellent perception of both details and color, with the lowest illuminance level about 15?lx.     

Evaluating Physician Communication Competence Scales: A Replication and Extension

Academic entitlement, a term used to reflect students' expectation for success regardless of personal effort, has become a growing issue at many universities. This study examined the relationship between college students' academic beliefs (i.e., academic entitlement, grade orientation, learner orientation, self-efficacy) and their motives for communicating with their instructor. Participants were 184 undergraduate students who completed a series of self-report scales. Students' level of academic entitlement was positively related to their grade orientation but negatively related to their self-efficacy. Results of a canonical correlation revealed that students who were learning oriented, but not grade oriented, and possessed self-efficacy communicated with their instructor for relational and participatory reasons. Students who were academically entitled and grade oriented communicated with their instructor for sycophantic reasons and to a lesser extent for participatory reasons but not for functional reasons.
