RESUMEN
A common goal of human-subject experiments in virtual reality (VR) research is evaluating VR hardware and software for use by the general public. A core principle of human-subject research is that the sample included in a given study should be representative of the target population; otherwise, the conclusions drawn from the findings may be biased and may not generalize to the population of interest. In order to assess whether characteristics of participants in VR research are representative of the general public, we investigated participant demographic characteristics from human-subject experiments in the Proceedings of the IEEE Virtual Reality Conferences from 2015-2019. We also assessed the representation of female authors. In the 325 eligible manuscripts, which presented results from 365 human-subject experiments, we found evidence of significant underrepresentation of women as both participants and authors. To investigate whether this underrepresentation may bias researchers' findings, we then conducted a meta-analysis and meta-regression to assess whether demographic characteristics of study participants were associated with a common outcome evaluated in VR research: the change in simulator sickness following head-mounted display VR exposure. As expected, participants in VR studies using HMDs experienced small but significant increases in simulator sickness. However, across the included studies, the change in simulator sickness was systematically associated with the proportion of female participants. We discuss the negative implications of conducting experiments on non-representative samples and provide methodological recommendations for mitigating bias in future VR research.

BACKGROUND: A joint practicum gives library and information science (LIS) students the opportunity to compare two health sciences libraries' structures and workflows. The goal of this case report is to describe how a joint health sciences practicum can help LIS students and recent graduates develop skills that may be beneficial for their future positions in health sciences or other libraries.Case Presentation: Six participants in a joint health sciences library practicum underwent two interviews: the first interview focused on their practicum experiences, and the second interview sought to determine whether the participants had found employment and were using any skills in their new positions that they acquired during their practicums. Participants gave mostly positive feedback regarding their practicum experiences and expressed openness to applying for health sciences library positions. Although the participants who found employment did not work in health sciences libraries, their practicum projects served as supporting materials for their job applications, and they were using the skills they had gained from their practicums in their new positions. CONCLUSIONS: While most joint practicum participants were not working in a health sciences library, the practicum was beneficial to their new careers. This case report highlights that a joint health sciences practicum program can be beneficial in showing LIS students different approaches to health sciences librarianship.

While women are generally underrepresented in STEM fields, there are noticeable differences between fields. For instance, the gender ratio in biology is more balanced than in computer science. We were interested in how this difference is reflected in the interdisciplinary field of computational/quantitative biology. To this end, we examined the proportion of female authors in publications from the PubMed and arXiv databases. There are fewer female authors on research papers in computational biology, as compared to biology in general. This is true across authorship position, year, and journal impact factor. A comparison with arXiv shows that quantitative biology papers have a higher ratio of female authors than computer science papers, placing computational biology in between its two parent fields in terms of gender representation. Both in biology and in computational biology, a female last author increases the probability of other authors on the paper being female, pointing to a potential role of female PIs in influencing the gender balance.

BACKGROUND: Ebola virus disease (hereafter EVD or Ebola) has a high fatality rate. The devastating effects of the current epidemic of Ebola in West Africa have put the global health response in acute focus. In response, the World Health Organization (WHO) has declared the Ebola outbreak in West Africa as a "Public Health Emergency of International Concern". A small proportion of scientific literature is dedicated to Ebola research. METHODS: To identify global research trends in Ebola research, the Institute for Scientific Information (ISI) Web of Science™ database was used to search for data, which encompassed original articles published from 1900 to 2013. The keyword "Ebola" was used to identify articles for the purposes of this review. In order to include all published items, the database was searched using the Basic Search method. RESULTS: The earliest record of literature about Ebola indexed in the Web of Science is from 1977. A total of 2477 publications on Ebola, published between 1977 and 2014 (with the number of publications increasing annually), were retrieved from the database. Original research articles (n = 1623, 65.5%) were the most common type of publication. Almost all (96.5%) of the literature in this field was in English. The USA had the highest scientific output and greatest number of funding agencies. Journal of Virology published 239 papers on Ebola, followed by Journal of Infectious Diseases and Virology, which published 113 and 99 papers, respectively. A total of 1911 papers on Ebola were cited 61,477 times. CONCLUSION: This analysis identified the current state of research and trends in studies about Ebola between 1977 and 2014. Our bibliometric analysis provides a historical perspective on the progress in Ebola research.

Sequences potentially associated with coffee resistance to diseases were identified by in silico analyses using the database of the Brazilian Coffee Genome Project (BCGP). Keywords corresponding to plant resistance mechanisms to pathogens identified in the literature were used as baits for data mining. Expressed sequence tags (ESTs) related to each of these keywords were identified with tools available in the BCGP bioinformatics platform. A total of 11,300 ESTs were mined. These ESTs were clustered and formed 979 EST-contigs with similarities to chitinases, kinases, cytochrome P450 and nucleotide binding site-leucine rich repeat (NBS-LRR) proteins, as well as with proteins related to disease resistance, pathogenesis, hypersensitivity response (HR) and plant defense responses to diseases. The 140 EST-contigs identified through the keyword NBS-LRR were classified according to function. This classification allowed association of the predicted products of EST-contigs with biological processes, including host defense and apoptosis, and with molecular functions such as nucleotide binding and signal transducer activity. Fisher's exact test was used to examine the significance of differences in contig expression between libraries representing the responses to biotic stress challenges and other libraries from the BCGP. This analysis revealed seven contigs highly similar to catalase, chitinase, protein with a BURP domain and unknown proteins. The involvement of these coffee proteins in plant responses to disease is discussed.

OBJECTIVE: To evaluate the influence of a web-based stress management program on neck-shoulder-back pain and perceived pain-relatedness to stress in a prospective and controlled study. METHODS: Study points were baseline, after 6 months intervention and at 12 months follow-up on 226 news media employees in two study groups and one control group. RESULTS: Between groups no significant differences were found at any study point. Within groups, the study group with less intensive program improved in pain-relatedness to stress at follow-up. Between baseline and after intervention, the group with more intensive program showed decreased low back pain, and the control group showed less pain-relatedness to stress. Within group differences varied according to pain localization and were inconsistent. CONCLUSION: Present web-based stress management program did not influence neck-shoulder-back pain or perceived pain-relatedness to stress in stress-intensive occupations.

BACKGROUND: Reduced sleep can be associated with a risk of health problems. Information technologies (IT) professionals often work long hours and this could have an effect on their sleep quality. AIMS: To examine the prevalence of sleep debt, insomnia and long working hours among Finnish IT professionals and to analyse which specific work-related factors are associated with shortened sleep. METHODS: Cross-sectional, representative data from a questionnaire survey of IT professionals. Hierarchical regression analyses were applied to investigate relationships of sleep debt and insomnia. RESULTS: A total of 2,334 IT professionals responded to the survey. Thirty-seven per cent reported sleep debt of at least 1 h and 6% of at least 2 h, while 16% reported insomnia. Twenty-seven per cent worked for a minimum of 50 h a week, while 31% spent at least 50 h a week on work. The most important factors associated with both sleep debt and insomnia were work-related demands requiring long hours, mental stamina and problem solving and positive perceptions of work, such as job control and importance of the respondents' own work in their life. CONCLUSIONS: Even though long working hours were common among IT professionals in Finland, sleep debt and insomnia were not. Work-related factors were associated with insufficient sleep.

OBJECTIVES: The purpose of this study is to assess whether recent graduates of the Ohio State University's Occupational Therapy division are applying information-seeking skills they learned as undergraduates, and to seek their advice on ways to improve information-literacy instruction for current and future occupational therapy students. METHOD: A survey was sent to a sample of graduates from 1995-2000. The results were entered into an SPSS database, and descriptive and inferential results were calculated to determine the information-seeking patterns of these recent graduates. RESULTS: A majority of the occupational therapy graduates who responded to the survey prefer to use information resources that are readily available to them, such as advice from their colleagues or supervisors (79%) and the Internet (69%), rather than the evidence available in the journal literature. Twenty-six percent (26%) of the graduates have searched MEDLINE or CINAHL at least once since they graduated. Formal library instruction sessions were considered useful by 42% of the graduates, and 22% of the graduates found informal contacts with librarians to be useful. CONCLUSIONS: Librarians and occupational therapy faculty must intensify their efforts to convey the importance of applying research information to patient care and inform students of ways to access this information after they graduate. In addition to teaching searching skills for MEDLINE and CINAHL, they must provide instruction on how to assess the quality of information they find on the Internet. Other findings suggest that occupational therapy practitioners need access to information systems in the clinical setting that synthesize the research in a way that is readily applicable to patient-care issues.

BACKGROUND: The rapidly expanding fields of genomics and proteomics have prompted the development of computational methods for managing, analyzing and visualizing expression data derived from microarray screening. Nevertheless, the lack of efficient techniques for assessing the biological implications of gene-expression data remains an important obstacle in exploiting this information. RESULTS: To address this need, we have developed a mining technique based on the analysis of literature profiles generated by extracting the frequencies of certain terms from thousands of abstracts stored in the Medline literature database. Terms are then filtered on the basis of both repetitive occurrence and co-occurrence among multiple gene entries. Finally, clustering analysis is performed on the retained frequency values, shaping a coherent picture of the functional relationship among large and heterogeneous lists of genes. Such data treatment also provides information on the nature and pertinence of the associations that were formed. CONCLUSIONS: The analysis of patterns of term occurrence in abstracts constitutes a means of exploring the biological significance of large and heterogeneous lists of genes. This approach should contribute to optimizing the exploitation of microarray technologies by providing investigators with an interface between complex expression data and large literature resources.

INTRODUCTION: The workload of histopathologists is traditionally assessed by the total number of specimens handled annually (TSA). Development in medical science has resulted in an increased demand by clinicians for more information in histopathology reports. Inclusion of this information requires more work. Annual information output (AIO) is the total number of specimens handled annually multiplied by the average number of items of information per histopathology report (AIR). An item of information is any pathological feature of prognostic or therapeutic relevance. OBJECTIVE: This study aims to determine whether there has been an increase in annual information output (AIO) during a 17-year period. METHOD: This is a retrospective study in a University Department of Pathology. 200 histopathology reports per year at 4 yearly intervals from 1982 to 1998 were examined. TSA, AIR and AIO were calculated. RESULTS: TSA increased from 2912 in 1982 to 3919 in 1998 (34.6% increase). AIR increased from 1.11 to 3.12 (181.1% increase). AIO increased from 3232.3 to 12227.3 (278.3% increase). CONCLUSION: The increase in AIO was greater than the increase in TSA. Thus the use of TSA alone will not reflect the increase in workload accurately. We recommend the use of AIO rather than TSA to quantify workload and staffing requirements of histopathologists.
