It has previously been shown that readers spend a great deal of time skim reading on the Web and that this type of reading can affect comprehension of text. Across two experiments, we examine how hyperlinks influence perceived importance of sentences and how perceived importance in turn affects reading behaviour. In Experiment 1, participants rated the importance of sentences across passages of Wikipedia text. In Experiment 2, a different set of participants read these passages while their eye movements were tracked, with the task being either reading for comprehension or skim reading. Reading times of sentences were analysed in relation to the type of task and the importance ratings from Experiment 1. Results from Experiment 1 show readers rated sentences without hyperlinks as being of less importance than sentences that did feature hyperlinks, and this effect is larger when sentences are lower on the page. It was also found that short sentences with more links were rated as more important, but only when they were presented at the top of the page. Long sentences with more links were rated as more important regardless of their position on the page. In Experiment 2, higher importance scores resulted in longer sentence reading times, measured as fixation durations. When skim reading, however, importance ratings had a lesser impact on online reading behaviour than when reading for comprehension. We suggest readers are less able to establish the importance of a sentence when skim reading, even though importance could have been assessed by information that would be fairly easy to extract (i.e. presence of hyperlinks, length of sentences, and position on the screen).

The Protein Data Bank (PDB) was established at Brookhaven National Laboratories in 1971 as an archive for biological macromolecular crystal structures. In mid 2021, the database has almost 180,000 structures solved by X-ray crystallography, nuclear magnetic resonance, cryo-electron microscopy, and other methods. Many proteins have been studied under different conditions, including binding partners such as ligands, nucleic acids, or other proteins; mutations, and post-translational modifications, thus enabling extensive comparative structure-function studies. However, these studies are made more difficult because authors are allowed by the PDB to number the amino acids in each protein sequence in any manner they wish. This results in the same protein being numbered differently in the available PDB entries. For instance, some authors may include N-terminal signal peptides or the N-terminal methionine in the sequence numbering and others may not. In addition to the coordinates, there are many fields that contain structural and functional information regarding specific residues numbered according to the author. Here we provide a webserver and Python3 application that fixes the PDB sequence numbering problem by replacing the author numbering with numbering derived from the corresponding UniProt sequences. We obtain this correspondence from the SIFTS database from PDBe. The server and program can take a list of PDB entries or a list of UniProt identifiers (e.g., "P04637" or "P53_HUMAN") and provide renumbered files in mmCIF format and the legacy PDB format for both asymmetric unit files and biological assembly files provided by PDBe.

Under conditions of the rapidly developing e-commerce sector especially during pandemic, ensuring high quality of courier service is essential both for clients, as well as courier companies. However, the literature lacks research linking the perspective of clients and organization in the context of courier service quality. The study aims to identify the factors determining courier service quality, their functions and interrelationships in business-to-customer (B2C) e-commerce. The main effect of research is the relational model, which is an original and complex approach to courier service quality considering the multi-stakeholder perspective of an online shop, a courier company and an e-customer. Apart from scientific contribution, the model can be used into managerial practice to formulate the recommendations for e-commerce and courier service sector. The research process involved using the quantitative method (electronic surveys conducted among e-shops and e-clients) and the qualitative method (in-depth-interviews carried out among courier enterprises). Finally, based on the empirical research results, the structural analysis was used to develop the model. As a result, the following groups of factors were distinguished that determine the quality of courier services: crucial, determinant, result, autonomous and external factors.

Web-based innovation indicators may provide new insights into firm-level innovation activities. However, little is known yet about the accuracy and relevance of web-based information for measuring innovation. In this study, we use data on 4,487 firms from the Mannheim Innovation Panel (MIP) 2019, the German contribution to the European Community Innovation Survey (CIS), to analyze which website characteristics perform as predictors of innovation activity at the firm level. Website characteristics are measured by several data mining methods and are used as features in different Random Forest classification models that are compared against each other. Our results show that the most relevant website characteristics are textual content, the use of English language, the number of subpages and the amount of characters on a website. In our main analysis, models using all website characteristics jointly yield AUC values of up to 0.75 and increase accuracy scores by up to 18 percentage points compared to a baseline prediction based on the sample mean. Moreover, predictions with website characteristics significantly differ from baseline predictions according to a McNemar test. Results also indicate a better performance for the prediction of product innovators and firms with innovation expenditures than for the prediction of process innovators.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has created several challenges for residency programs and prospective interns alike during the upcoming application cycle, including the cancellation of away sub-internships and in-person interviews. Given prior research documenting that applicants' application and ranking decisions are significantly influenced by residency webpages, a potential solution to the loss of in-person experiences during the pandemic is the expansion of residency programs' online presence through their program websites, provision of virtual grand rounds and pseudo-away rotations, and enhancement of virtual interviews. This study seeks to summarize the existing literature on these areas and provide concrete suggestions for improving programs' virtual presence.Methods: The authors summarize earlier literature querying the content of program websites across 14 medical specialties, which documented significant gaps in the content of interest to applicants.Results: Among 14 analyzed specialties, the majority of programs had a functional website (>90%), with the exception of interventional radiology (73.9%). However, significant gaps in content were documented, with the percentage of content variables contained on websites ranging from 33.3% to 70.5% (median = 47.0%, interquartile range = 37.8-52.6%). Program websites were also limited by underrepresentation of content most valued by applicants as well as potential areas of inaccurate or outdated information.Conclusions: There are several interventions programs can undertake to address existing gaps in online presence. During an application cycle facing unprecedented resource strain, bolstering the online presence of programs may facilitate an improved fit between programs and future residents.

The prediction of web service quality plays an important role in improving user services; it has been one of the most popular topics in the field of Internet services. In traditional collaborative filtering methods, differences in the personalization and preferences of different users have been ignored. In this paper, we propose a prediction method for web service quality based on different types of quality of service (QoS) attributes. Different extraction rules are applied to extract the user preference matrices from the original web data, and the negative value filtering-based top-K method is used to merge the optimization results into the collaborative prediction method. Thus, the individualized differences are fully exploited, and the problem of inconsistent QoS values is resolved. The experimental results demonstrate the validity of the proposed method. Compared with other methods, the proposed method performs better, and the results are closer to the real values.

Engagement with scientific manuscripts is frequently facilitated by Twitter and other social media platforms. As such, the demographics of a paper's social media audience provide a wealth of information about how scholarly research is transmitted, consumed, and interpreted by online communities. By paying attention to public perceptions of their publications, scientists can learn whether their research is stimulating positive scholarly and public thought. They can also become aware of potentially negative patterns of interest from groups that misinterpret their work in harmful ways, either willfully or unintentionally, and devise strategies for altering their messaging to mitigate these impacts. In this study, we collected 331,696 Twitter posts referencing 1,800 highly tweeted bioRxiv preprints and leveraged topic modeling to infer the characteristics of various communities engaging with each preprint on Twitter. We agnostically learned the characteristics of these audience sectors from keywords each user's followers provide in their Twitter biographies. We estimate that 96% of the preprints analyzed are dominated by academic audiences on Twitter, suggesting that social media attention does not always correspond to greater public exposure. We further demonstrate how our audience segmentation method can quantify the level of interest from nonspecialist audience sectors such as mental health advocates, dog lovers, video game developers, vegans, bitcoin investors, conspiracy theorists, journalists, religious groups, and political constituencies. Surprisingly, we also found that 10% of the preprints analyzed have sizable (>5%) audience sectors that are associated with right-wing white nationalist communities. Although none of these preprints appear to intentionally espouse any right-wing extremist messages, cases exist in which extremist appropriation comprises more than 50% of the tweets referencing a given preprint. These results present unique opportunities for improving and contextualizing the public discourse surrounding scientific research.

OBJECTIVES: To highlight the self-reported experiences and disease perceptions of infertile women with polycystic ovary syndrome (PCOS). METHODS: A qualitative study using an inductive method was conducted on infertile women with PCOS who shared their self-reported experiences on French-speaking on-line forums. RESULTS: 785 comments by 211 women on 7 forums were analyzed. Women complained of late diagnosis and lack of information regarding PCOS. PCOS and infertility showed negative psychological impact on daily life. This impact appeared to be alleviated by the sharing of knowledge and experience enabled by these forums. CONCLUSION: The self-reported experience of infertile women with PCOS is interesting for health practitioners. The psychological impact of PCOS and perceptions of illness appear to be improved by sharing experiences between women with PCOS, suggesting a beneficial support role of online discussion forums.

Training and education are essential for medical students. During the COVID-19 outbreak, numerous schools and universities have had to close. Ensuring pedagogical continuity requires alternatives to the traditional classroom, especially in medical education. Usual distance learning tools such as videos and downloadable handouts are not sufficient to promote efficient teaching. Distance learning requires self-motivation and does not give you direct access to your instructor. Some students fear the loss of human contact with an instructor - like asking questions during and after class - which promotes learning, understanding and communication. Moreover, classical distance learning methods do not offer immediate feedback that can help students in their understanding of the lecture. In this context, interactive pedagogic tools (IPT) could be useful for medical education continuity and for maintaining human contact necessary in pedagogy. We briefly evaluated interactive pedagogic tool compared to traditionnal distancial tools on medical students. This study showed the importance to have direct contact with a teacher and feedback during a lecture and to not exclusively perform distance learning without direct interaction and feedback. Hence, in the present context, we encourage teacher to use this type of tools to maintain direct interaction with students - which is essential in pedagogy - and ensure a qualitative pedagogical continuity.

Learning using the Internet or training through E-Learning is growing rapidly and is increasingly favored over the traditional methods of learning and teaching. This radical shift is directly linked to the revolution in digital computer technology. The revolution propelled by innovation in computer technology has widened the scope of E-Learning and teaching, whereby the process of exchanging information has been made simple, transparent, and effective. The E-Learning system depends on different success factors from diverse points of view such as system, support from the institution, instructor, and student. Thus, the effect of critical success factors (CSFs) on the E-Learning system must be critically analyzed to make it more effective and successful. This current paper employed the analytic hierarchy process (AHP) with group decision-making (GDM) and Fuzzy AHP (FAHP) to study the diversified factors from different dimensions of the web-based E-Learning system. The present paper quantified the CSFs along with its dimensions. Five different dimensions and 25 factors associated with the web-based E-Learning system were revealed through the literature review and were analyzed further. Furthermore, the influence of each factor was derived successfully. Knowing the impact of each E-Learning factor will help stakeholders to construct education policies, manage the E-Learning system, perform asset management, and keep pace with global changes in knowledge acquisition and management.

BACKGROUND: National and international aesthetic surgery society websites are an important source of information for patients and aesthetic surgeons. The current COVID-19 pandemic represents an unprecedented global health crisis. The aim of this study was to assess the information available on national and international aesthetic surgery society websites on the current pandemic of COVID-19. METHODS: National and international aesthetic surgery society websites were assessed with regard to COVID-19 information. RESULTS: Thirty-one per cent of nations had aesthetic surgery society websites. Twenty-two per cent of national society websites had a specific COVID-19 section. Seventeen per cent of these websites had COVID-19-specific guidelines available; of these websites with guidelines, 77% had a specific COVID-19 section advising to provide only urgent or emergent care and 46% provided their sovereign state's directives to provide only urgent or emergent care. Two international aesthetic surgery society websites had COVID-19-specific guidelines, and one of the two had significant educational resources. CONCLUSION: The availability of COVID-19 clinical guidelines and patient information sheets on national plastic surgery society websites is sparse. In contrast, one international society website carefully analysed national and international recommendations and guidelines and made general recommendations for its members with regularly updated resources. This study suggests that improvement and increase in COVID-19 information provided by many national aesthetic surgery society websites may be improved by links to the ISAPS website.

BACKGROUND: Vaccine hesitancy is a major issue in general practice. Regarding human papillomavirus, less than 20% of young French girls are vaccinated. With widespread availability of health information, the Internet seems to be a place of choice to discuss this reluctance. The main objective of this study was to explore perceptions of human papillomavirus vaccination through an analysis of the Doctissimo.fr forum data. METHODS: Using Nvivo software, a qualitative study was carried out from October 2017 to May 2018 on the Doctissimo.fr discussion forum. Online discussion threads not having any message since 2010 were excluded. All threads were analyzed by two independent evaluators. RESULTS: Faced with the doubt that emanated from the discussions and the confusion about the role of the vaccine, Internet users used multiple references in order to develop a reliable discourse. The general practitioner remained a trusted person. While the vaccine was perceived as risky, the cervical smear was approved and encouraged. Although the vaccine remained a feminine concern, males also entered this debate. Through their shared experiences, Internet users tried to influence others about whether or not to get vaccinated. CONCLUSION: Changing the sexual image of the vaccine could help to establish a collective vaccination policy. Public health policies play an essential role by working with general practitioners and by increasing visibility on the web. The usefulness of the vaccine in 2019 seems to be questioned by Internet users as shown by their major approval of cervical smears. However, these two methods remain complementary in the fight against cervical cancer.

Investigational treatments are those that have been approved for testing in humans but are not yet available as an approved treatment option. For many patients with a terminal illness who have no approved treatment option and are not eligible for a clinical trial, investigational treatments are the last resort. However, not much is known about the dissemination of information by patient advocacy organizations (PAOs). We evaluated the quantity and quality of information on preapproval access to investigational therapies provided by Japanese PAO websites between January 24 and March 29, 2019. A total of 49 PAOs were identified. Of these, 16 (33%) provided no relevant information. The most frequent information provided was the PAO's own clinical trial finder or list of clinical trials (n = 15, 31%); of the 10 cancer-related PAOs, 5 (50%) provided this information. Nine (18%) PAOs had developed patient registries or provided a link to relevant registries. Only 1 PAO (2%) provided a link about the Ministry of Health, Labour, and Welfare trials that described the process and regulations of clinical trials. Our results indicate that PAOs do not disseminate adequate information on preapproval pathways. We suggest that the government involve PAOs in disseminating this information to both patients and physicians.

OBJECTIVE: To evaluate the informativity, quality of French discussion forums for evaluation of baclofen safety. METHODS: We evaluated the quality of potential pharmacovigilance case reports associated to baclofen in 22 French discussion forums. We compared the informativity concerning the patient, treatment, seriousness and expectedness of adverse events described on these posts, with similar information coded in case reports from the French pharmacovigilance database (FPVD). RESULTS: A total of 782 potential case reports were identified among 2621 French language forums' posts. Cases in the FPVD were significantly more informative than web forums' posts for patient information (3%/6% vs. 88% for the age/class of age and 46% vs. 99% for the gender), treatment duration (9% vs. 24%) and outcome of the ADR (1% vs. 64%). But both indication and dose were more frequently retrieved in forums than in the FPVD (67% vs. 24% and 27% vs. 9%, respectively). Cases from web forums were significantly more frequently non-serious than the FPVD's ones (38% vs. 0.7%). Adverse events were significantly more often unexpected in forums than in the FPVD (43.8% vs. 11.6%). CONCLUSION: Indication and posology were more often documented in posts than in case reports which makes forums an interesting resource for monitoring use of baclofen. While posts contain more unexpected events, informativity is low which makes causality assessment difficult. Nevertheless, we consider forums as a secondary, but complementary source for pharmacovigilance about baclofen.

Introduction: We describe a teledermatology infrastructure, implemented as part of a statewide large-scale telemedicine network, designed to provide comprehensive support for examination and clinical management protocols, which includes telediagnostic and patient triage and referral. It was implemented as a web-based system and an associated mobile application that supports both the primary healthcare facility team and the specialist during the patient care process. Methods: We describe the process models, protocols and technology employed, and the requirements generated for their development. We also present the results and experiences gained in implementing the model. The teledermatology service was implemented in 313 primary healthcare facilities in 286 municipalities in the State of Santa Catarina, Brazil. This study covers the period from January 2014 to June, 2018. Results: During this period, the teledermatology infrastructure processed 83,100 teledermatology examinations, of which 75,832 were validated and employed for patient triage and clinical management. Teledermatology allowed 33,112 patients to avoid further referral and be treated locally. Of this cohort, 7,513 patients presented more complex dermatoses that could be treated at the primary care level using telehealth-supported clinical management. Conclusions: Results indicate that this model contributes not only to the resolution of cases at the primary care level but also to the progressive improvement of the technical quality of dermatological examinations performed by technical staff at the primary healthcare.

People with suicidal ideation (PSI) are increasingly using social media to express suicidal feelings. Researchers have found that their internet-based communication may lead to the spread of suicidal ideation, which presents a set of challenges for suicide prevention. To develop effective prevention and intervention strategies that can be efficiently applied in online communities, we need to understand the behavior of PSI in internet-based communities. However, to date there have been no studies that specifically focus on the behavior of PSI in Chinese online communities. A total of 4489 postings in which users explicitly expressed their suicidal ideation were labeled from 560,000 postings in an internet-based suicidal community on Weibo (one of the biggest social media platforms in China) to explore their behavior. The results reveal that PSI are significantly more active than other users in the community. With the use of social network analysis, we also found that the more frequently users communicate with PSI, the more likely that users would become suicidal. In addition, Chinese women may be more likely to be at risk of suicide than men in the community. This study enriches our knowledge of PSI's behavior in online communities, which may contribute to detecting and assisting PSI on social media.
