Abstract The Incorporated Research Institutions for Seismology Earthquake Browser (IEB; see Data and Resources) is a web-based tool that enables anyone to query an earthquake database composed of over five million events recorded over the past 50 yr. The IEB visitor can query on earthquake magnitude, depth, timing, and location and can visually display the results in 2D map view or as an interactive pseudo 3D view. The user can toggle features such as plate tectonic boundaries, terrain or satellite mapping, and zoom to place the results in a geologic or geopolitical context and add visual appeal. To better understand who visits the IEB and why, to include information on demographics and how users perceive the IEB functionality and ability to meet their needs, we conducted a pop-up user survey on the IEB from 25 January to 21 February 2018. We received 495 useable responses from 58 countries, with 40% of the total respondents from the United States. The largest demographic consists of interested citizens who are 55 yr of age or older and have a high school education. We also find that visitors come to the IEB to learn about earthquakes for two main reasons: for their own personal knowledge or because expanding their knowledge is important to their research or work in a professional context. We also find a dramatic increase in survey respondent activity following the 16 February 2018 M 7.2 Oaxaca, Mexico, earthquake, with many respondents interested in finding more information about recent earthquake events that affect them or their family. Our observations indicate that users are successful and satisfied with the ease of use and amount of time spent on the IEB to find answers to their questions about earthquakes. The most beneficial feature of the IEB as identified by survey respondents is the spatiotemporal visual display of real earthquake data.

This article illustrates a web-based conversational learning system termed, “Virtual Grand Rounds in Dermatology” (VGRD), that was developed by two dermatologist colleagues from the United States and Malaysia, respectively, over the past decade. Two blog posts discussing the diagnostic uncertainty around possible dermatological manifestations of lupus are highlighted along with a few conversational comments from other health professionals. The posts, as they appear on VGRD are presented verbatim and illustrate a health professional narrated website that relies heavily on images and pattern recognition. We show that health professional learning may thrive on feedback from colleagues, even if minimal.

Final Year Project (FYP) is a compulsory requirement for graduation of every bachelor programme in Universiti Teknologi MARA (UiTM). Finding a topic for the final year project is quite challenging. However, being able to access previous FYP thesis helps students to generate some ideas. Supervisors and lecturers can also determine whether the proposed project is already among the previous research project or a new one. Unfortunately, the past FYP thesis is usually kept in a specific thesis room. Hence, this will make going to the thesis room and searching the thesis for references quite burdensome. The lack of electronic management for FYP thesis causes several problems in arrangement and search methods. This project aims to develop Smart Final Year Project Archive System (SFYPAS) using Laravel Framework and evaluate the system in terms of technology acceptance model (TAM). SFYPAS is developed using Laravel framework and the methodology used throughout the project is using Software Development Life Cycle (SDLC). The system tested based on its functionality, user acceptance with TAM and heuristic evaluation by an expert. The system was tested on thirty respondents who shared their feedback by answering a set of questionnaires upon completing the testing. The result shows that the mean for user acceptance with TAM in terms of perceived ease of use is 4.27, while perceived usefulness is 4.47. Thus, it shows that the respondents are satisfied with the system in terms of its perceived usefulness. In conclusion, this research has achieved the objectives where it eases the user by providing a web-based smart archive system as a platform to access the past FYP thesis. For future work, the system can be improved by adding a search engine that implements any searching algorithm to yield a better result.

Invigilation of the examination is one of the important roles and tasks of lecturers appointed as invigilators or proctors. Based on the past semi-annually reports of examination post-mortems meeting, less than 10% of the invigilators were unhappy with the examination duties that have been assigned or appointed to them. The examination committee members who are responsible in the process of assigning the invigilation duties to each invigilator had given a lot of effort and spent a few weeks to ensure that everybody is happy with the invigilation duties assigned to them. Nevertheless, despite the excellent planning of invigilation duties assignment, it cannot make everybody satisfied. Thus, a web-based application system named Examination Invigilation Management Systems (ExIMS) has been developed using the System Development Life Cycle (SDLC) waterfall model methodology to meet the need of invigilation duties exchanged among invigilators or applicants. This system has been developed to control and cross check the request of invigilation duties exchanged using the algorithm named multi selection control. The algorithm could avoid any conflicts or anomalies that could happen after the exchange of duty has been made. The process of duty exchange is examined and verified automatically by the system. The system provides a platform for users or invigilators to give their views or opinions on the invigilation duties and system features or performance through the online survey. The survey uses the TAM method concentrating on the perceived-ease-of-use (PEOU) component. Based on the survey, 95% respondents reported that they were satisfied with the platform for duty exchange among invigilators. The users can easily and flexibly select the new duties, which will be automatically and mutually swapped among invigilators. ExIMS has solved the problem of unsatisfaction of invigilation duties and increased the happiness index among invigilators during the examination period.

Grant-supported digitization projects over the past 20 years at the Illinois Natural History Survey (INHS) have yielded over 1,000,000 occurrence records (representing over 2.7 million specimens), one of the most successful digitization efforts within the United States. However, receiving multiple grants at the cutting edge has led to numerous projects left at various stages of completeness, several relational databases, orphaned data, and specimens at various stages of curation. TaxonWorks (taxonworks.org), an integrated web-based workbench developed by the Species File Group and supported by the INHS and the National Science Foundation, has provided the digital infrastructure to unify multiple workflows, projects, databases, and even historical accession books into one easy to access, open-source platform. We demonstrate the practical utility of this platform and summarize past, present, and future efforts at the INHS towards integrating all our data within TaxonWorks.

Background: Healthcare workers are at the forefront of the COVID-19 pandemic and it is essential to monitor the relative incidence rate of this group, as compared to workers in other occupations. This study aimed to produce estimates of the relative incidence ratio between healthcare workers and workers in non-healthcare occupations. Methods: Analysis of cross-sectional data from a daily, web-based survey of 1,822,662 Facebook users from September 8, 2020 to October 20, 2020. Participants were Facebook users in the United States aged 18 and above who were tested for COVID-19 because of an employer or school requirement in the past 14 days. The exposure variable was a self-reported history of working in healthcare in the past four weeks and the main outcome was a self-reported positive test for COVID-19. Results: On October 20, 2020, in the United States, there was a relative COVID-19 incidence ratio of 0.73 (95% UI 0.68 to 0.80) between healthcare workers and workers in non-healthcare occupations. Conclusions: In fall of 2020, in the United States, healthcare workers likely had a lower COVID-19 incidence rate than workers in non-healthcare occupations.

BACKGROUND The Centers for Disease Control and Prevention estimates that 1.1 million people in the United States are living with HIV and 1 in 8 are estimated to be unaware of their serostatus. Little is known about whether individuals would consider being tested for HIV in nontraditional health care settings such as a dentist’s office. Studies in selected US cities have indicated high acceptability of receiving an HIV test among people attending dental clinics. However, we are not aware of studies that have assessed willingness to receive HIV testing in dental care settings at a national level. OBJECTIVE Using a web-based sample of adult residents of the United States, we sought to assess the self-reported willingness to receive any type of HIV testing (ie, oral fluid rapid testing, finger-stick blood rapid testing, or venipuncture blood testing) in a dental care setting and evaluate independent associations of willingness with the extent to which dental care providers were perceived as knowledgeable about HIV and how comfortable participants felt discussing HIV with their dental care providers. METHODS Participants were recruited using banner advertisements featured on social networking platforms (Facebook and Instagram) from December 2018 to February 2019. Demographic and behavioral data including information on sexual behaviors in the past 6 months, HIV testing history, and dental/health care–seeking history were collected using an anonymous web-based survey. Willingness to receive any type of HIV testing in a dental care setting was assessed on 4-point scale from very willing to very unwilling. Factors independently associated with participants’ willingness were identified using a multivariable logistic regression model. RESULTS Of the 421 participants in our study aged 18 to 73 years, 271 (64.4%) reported having oral sex, 197 (46.8%) reported having vaginal sex, and 136 (32.3%) reported having anal sex in the past 6 months. Approximately one-third had never been tested for HIV (137/421, 32.5%), and the same proportion had not been tested in the past year (137/421, 32.5%). Most participants had dental insurance coverage (356/421, 84.6%), and more than three-fourths reported being very or somewhat willing (326/421, 77.4%) to receive any type of HIV testing in a dental care setting. Higher levels of willingness were associated with being 18 to 24 years versus ≥35 years (aOR 3.22, 95% CI 1.48-6.98), 25 to 34 years versus ≥35 years (aOR 5.26, 95% CI 2.52-10.98), believing that one’s dental care provider is knowledgeable about HIV (aOR 2.04, 95% CI 1.06-3.92), and feeling comfortable discussing HIV with one’s dental care provider (aOR 9.84, 95% CI 3.99-24.27). CONCLUSIONS Our data indicate high acceptability of receiving HIV testing in a dental care setting, especially among those who report having a positive patient-provider relationship. Future research should focus on assessing dental care providers’ attitudes, self-efficacy, and beliefs about whether HIV testing fits into the scope of dentistry.

The authors in this article first identify the extent to which research articles published in three American Speech-Language-Hearing Association (ASHA) journals included participants, age birth to 18 years, from international backgrounds (i.e., residence outside of the United States), and go on to describe associated publication patterns over the past 12 years. These patterns then provide a context for examining variation in the conceptualization of ethnicity on an international scale. Further, the authors examine terminology and categories used by 11 countries where research participants resided. Each country uses a unique classification system. Thus, it can be expected that descriptions of the ethnic characteristics of international participants involved in research published in ASHA journal articles will widely vary.

Abstract. Background: In recent years, the rate of death by suicide has been increasing disproportionately among females and young adults in the United States. Presumably this trend has been mirrored by the proportion of individuals with suicidal ideation who attempted suicide. Aim: We aimed to investigate whether the proportion of individuals in the United States with suicidal ideation who attempted suicide differed by age and/or sex, and whether this proportion has increased over time. Method: Individual-level data from the National Survey on Drug Use and Health (NSDUH), 2008–2017, were used to estimate the year-, age category-, and sex-specific proportion of individuals with past-year suicidal ideation who attempted suicide. We then determined whether this proportion differed by age category, sex, and across years using random-effects meta-regression. Overall, age category- and sex-specific proportions across survey years were estimated using random-effects meta-analyses. Results: Although the proportion was found to be significantly higher among females and those aged 18–25 years, it had not significantly increased over the past 10 years. Limitations: Data were self-reported and restricted to past-year suicidal ideation and suicide attempts. Conclusion: The increase in the death by suicide rate in the United States over the past 10 years was not mirrored by the proportion of individuals with past-year suicidal ideation who attempted suicide during this period.
