Purpose The purpose of this paper is to examine the relationship between electronic journal downloads and citations and whether online electronic resource usage can be adopted as an alternative to citation for evaluation of scholarly discourse. Design/methodology/approach A consolidated 16 publishers’ COUNTER usage data of UGC-Infonet members was collected from INFLIBNET Centre. The usage was meticulously filtered from UGC-subscribed journals and institutional subscriptions. The quantitative data were analysed to establish the relationship between download, impact factor (IF) and price. Multiple regression analysis was used to assess the influence of price and IF on usage and to predict the usage when they are known and the threshold for significance was set at p < 0.05. Findings There exists a relationship between IF and downloads of journals in UGC-Infonet. Journal IF and price significantly influence usage, where journal IF plays an important role in the intensity of the use. Also, the top 25 hottest downloaded papers were journals with IF; hence, no journal without IF featured in the top 25 most downloaded journals in the consortia. The relationship between the top 25 IF journals in the consortia and download is strong (r = 0.368537). Originality/value The only account that reports on the relationship between journal IFs and downloads for UGC-Infonet consortia. Also, the influence of usage behaviour with respect to citation and price of a journal.

Full textAbstract:
As universities cut library funding and forego expensive journal subscriptions, many academic organizations and researchers, including the American Educational Research Association (AERA), are moving toward open-access publications that are freely downloadable by anyone with a working internet connection. However, the impact of paywalls on the consumption of academic articles is unclear. We provide novel evidence on this question by exploiting a natural experiment in which six high-impact, usually gated AERA journals became open access for a 2-month period in 2017. Using monthly download data and an always-open-access journal as a comparison group, we show that making journals open access likely increased article downloads in those journals by 55% to 95% per month. Given a per-article download price of $36, this suggests a relatively elastic response: The average price elasticity of demand for downloads is 1.2, with individual journal elasticities ranging from 0.6 to 2.

Abstract Objectives We previously reported that random assignment of scientific articles to a social media exposure intervention did not have an effect on article downloads and citations. In this paper, we investigate whether longer observation time after exposure to a social media intervention has altered the previously reported results. Methods For articles published in the International Journal of Public Health between December 2012 and December 2014, we updated article download and citation data for a minimum of 24-month follow-up. We re-analysed the effect of social media exposure on article downloads and citations. Results There was no difference between intervention and control group in terms of downloads (p = 0.72) and citations (p= 0.30) for all papers and when we stratified by open access status. Conclusions Longer observation time did not increase the relative differences in the numbers of downloads and citations between papers in the social media intervention group and papers in the control group. Traditional impact metrics based on citations, such as impact factor, may not capture the added value of social media for scientific publications.

Full textAbstract:
Abstract Objective Scientific journals and authors are frequently judged on ‘impact’. Commonly used traditional metrics are the Impact Factor and H-index. However, both take several years to formulate and have many limitations. Recently, Altmetric—a metric that measures impact in a non-traditional way—has gained popularity. This project aims to describe the relationships between subject matter, citations, downloads and Altmetric within rheumatology. Methods Data from publications in Rheumatology were used. Articles published from 2010 to 2015 were reviewed. Data were analysed using Stata 14.2 (StataCorp, College Station, TX, USA). Correlation between citations, downloads and Altmetric were quantified using linear regression, comparing across disease topics. Relationship between downloads and months since publications were described using negative binomial regression, clustering on individual articles. Results A total of 1460 Basic Science and Clinical Science articles were identified, with the number of citations, downloads and Altmetric scores. There were no correlations between disease topic and downloads (R2 = 0.016, P = 0.03), citations (R2 = 0.011, P = 0.29) or Altmetric (R2 = 0.025, P = 0.02). A statistically significant positive association was seen between the number of citations and downloads (R2 = 0.29, P < 0.001). No correlations were seen between Altmetric and downloads (R2 = 0.028, P < 0.001) or citations (R2 = 0.004, P = 0.445). Conclusion Disease area did not correlate with any of the metrics compared. Correlations were apparent with clear links between downloads and citations. Altmetric identified different articles as high impact compared with citation or download metrics. In conclusion: tweeting about your research does not appear to influence citations.

Full textAbstract:
Download ash and emission dust samples were collected from sintering, coking, ironmaking and steelmaking processes of iron and steel enterprises in Laiwu. Sixteen kinds of polycyclic aromatic hydrocarbons (PAHs) in the United States Environmental Protection Agency (USEPA) priority controlled lists were quantitatively analyzed using Gas Chromatography-Mass Spectrometer (GC-MS). Laser particle size analyzer was used to obtain the distribution pattern of download ash. It was found that the diameter distribution pattern from four production processes was quite different. The proportion of fine particulate (0–2.5 μm) was the highest (72.62%) in the steelmaking refining process, and was 28.962% in the ironmaking process. Moreover, the particle size in download ash from steelmaking refining is all less than 10 μm and that from the ironmaking process was 52.92%. The medium-sized particles (10–100 μm) were dominant in sinter and coking download ashes. The total PAHs (∑16PAHs) mass concentration ranged from 0.49 ± 0.06 to 69.63 ± 5.57 μg·g−1 in download ash samples, and varied from 2.815 ± 0.253 to 19.429 ± 2.545 μg·m−3 in emission dust samples. The ∑16PAHs values were both largest in download ash and dust emission from the coking process (69.63 ± 5.57 μg·g−1 and 19.429 ± 2.545 μg·m−3, respectively). The most abundant individual PAHs were benzo[b]fluoranthene, benzo[k]fluoranthene, phenanthrene, benzo[a]anthracene in ash samples, and benzo[a]anthracene, benzo[k]fluoranthene, benzo[b]fluoranthene and indeno[1,2,3-cd]pyrene in emission dust samples. Dominant compounds were high-molecular weight (four- to six-ring) PAHs in both ash and dust samples. The concentration order of individual compounds in PM10 and PM2.5 in ambient air around the steel plant was completely consistent with each other, and the concentration of ∑16PAHs was the highest in the steel plant and lowest in Daqin village because of upwind of the steel plant. The concentrations of benzo[b]fluoranthene and fluoranthene in ambient air were comparatively high, and were in accordance with the higher concentration of the two monomers in the download ash samples, which suggested that the effect of the emission flue gas from the steel plant on ambient air was necessary to concern.

With the extensive growth of the Internet and electronic commerce, the issue of how users behave when confronted with long download times is important. This paper investigates Web switching behavior. The paper describes experiments where users were subjected to artificially delayed Web page download times to study the impact of Web site wait times on switching behavior. Two hypotheses were tested. First, that longer wait times will result in increased switching behavior. The implication being that users become frustrated with long waiting times and choose to go elsewhere. Second, that users who switch will benefit, in terms of decreased download times, from their decision to switch.

The existence of innovative learning allows dynamism in learning. The presence of technology in the world of education is to help teachers and students to obtain the speed of information, create innovative learning, and facilitate all teaching and learning activities. One result of technology that can be utilized in learning is the presence of a smartphone. On the smartphone, there is a QR Code media that can be downloaded via Google Play. One of the sociological materials, namely social conflict is the choice to be presented with QR Code media. The implementation is that students from one of the groups download the QR Code on their smartphone so that they can scan the assignments given by the teacher in the form of barcodes. Previously the teacher had prepared questions about the subject of social conflict in the form of barcodes. Gurupun also download a barcode generator on a smartphone to be able to write the problem, then the final result in the form of a barcode. The results in the form of barcodes are then printed. Then students do the scanning on the printed barcode and the task or problem to appear will appear. Completion of tasks is done in groups so as to accelerate the process. Learning with QR Code media also includes 21st century educational abilities, including literacy, strengthening character education, and 4C (critical, communicative, collaborative, and creative). By using the QR Code media it turns out to be very effective in fostering students' interest in studying sociology. Keywords : Innovative learning, QR Code, Barcode Generator, Scaning, Social Conflict

Abstract
Objective – To test a new model for measuring journal impact by using principles of social networking. Research questions are as follows:
1. Can valid networks of journal relationships be derived from reader article download patterns registered in a digital library’s server logs?
2. Can social network metrics of journal impact validly be calculated from the structure of such networks?
3. If so, how do the resulting journal impact rankings relate to the ISI impact factor (IF)?
Design – Bibliometric, social network centrality analysis
Setting – Los Alamos National Laboratory (LANL), New Mexico
Subjects – 40,847 full-text articles downloaded from a large digital library by 1,858 unique users over a 6 month period.
Methods – Full-text article downloads from a large digital library for a six-month period were examined using social networking analysis methods. ISSNs for journals in which the retrieved articles were published were paired based upon the proximity of use by the same user, based on the supposition that proximal downloads are related in some way. Reader-Generated Networks (RGNs) were then tested for small-world characteristics. The resulting RGN data were then compared with Author-Generated Networks (AGNs) for the same journals indexed in the Institute of Scientific Information (ISI) annual impact factor (IF) rankings, in the Journal Citation Reports (JCR) database. Next, a sample of the AGN-derived pairings was examined by a team of 22 scientists, who were asked to rate the strength of relationships between journals on a five-point scale. Centrality ratings were calculated for the AGN and RGN sets of journals, as well as for the ISI IF.
Main results – Closeness and centrality rankings for the ISI IF and the AGN metrics were low, but significant, suggesting that centrality metrics are an acceptable impact metric. Comparison between the RGN and ISI IF data found marked differences, with RGN mirroring local population needs to a much higher degree, and with a non-significant correlation between the ISI IF and RGN ranking, while AGN and RGN centrality rankings show significant centrality and closeness and betweenness correlations. RGN network ranking identified highly localized foci of interest for the LANL, as well as “interest-bridging” subject areas pointing to possible emerging interests among the scientists.
Conclusion – The study results appear to successfully demonstrate an alternative to existing journal impact ranking that can more validly and accurately reflect the practices of a local community. The authors suggest that the social network-derived methodology for identification of impact rankings avoids biases intrinsic to ISI IF as a result of frequentist metrics collected from a global user group. Although the authors resist the idea of generalizability due to the local nature of their data, they suggest that the methodology can be successfully used in other settings, and for a more global community. Finally, the authors propose the automated creation of an open-source RGN whose data could be localized for smaller communities, with potentially large implications for the existing publishing industry.

e13590 Background: Routine monitoring of cancer patients' symptoms during their journey can improve symptom management, quality of life, and survival. Wecancer App is an electronic patient-reported outcome tool, which also provides on-demand multidisciplinary digital support by nurses, psychologists and nutritionists. It also encompasses real time remote patient monitoring, symptoms diary to patient and medical staff, symptom monitoring, medication control and a content hub with reliable information. It is free to any patient who download the app. In this study, we aim to understand if insurance provider type (private, public or out of pocket) impact on app adherence. Methods: This study examined daily symptom reporting (with electronic patient-reported outcomes [e-PROs]) patterns in breast cancer patients, according to insurance provider. The following were observed: app adherence, numbers of reports, chat interactions, specific symptoms, symptoms alerts and wellness reports. Patients could report sixteen common symptoms through a mobile application, on their smartphones and tablets, for monitoring, symptom management and follow-up with a specialized nurse, determining care based on digital support clinical protocols through online chat. The nursing team action started at the moment of patient inclusion with the tutorial to download the App and training it with the patient/caregiver. The alerts made through the chat system guided the clinical actions of the nursing team in relation to online clinical management that can stratify the risk by crossing the intensity of symptoms by the CTCAE grading scale and PRO-CTCAE Measurement System and promote preventive educational conduct of vigilance and risk mitigation. Results: From January 2020 to January 2021, 543 female eligible patients downloaded the app. The e-PRO completion rates were superior to 90% at baseline, and 55.47% completed all on-treatment assessments. The app adherence for private insurance patients (PIP), 37.06% for public insurance patients (PIP) and 7.45% for out of pocket patients (OPP). 2,626 reports were made (46.41% IP; 28.58% OPP; 25% PHP); 1008 chat interactions (52.18% IP; 40.28% PHP; 7.54% OPP); 1144 number of symptoms reported (46,41% IP; 28.58% OPP; 25% PHP); specific symptoms most reported in all kind of service was tiredness, pain, nausea, tingling; 547 symptoms alerts (54.84% IP; 35.46% PHP; 9.7% OPP) and 451 wellness reports (55.43% IP; 35.03% PHP; 9.53% OPP). Conclusions: Private insurance patients are more adherent to ePROS than public insured or out of pocket patients. Lack of free internet access and digital literacy could be impacting on adherence and, ultimately, quality of life and survival. Further studies are warranted to understand how to improve equality for digital health tools.

Objectives: In Austria, research in health technology assessment (HTA) has been conducted since the 1990s. The aim of this study is to analyze whether the HTA research program of the Institute of Technology Assessment (ITA) and the Ludwig Boltzmann Institute for HTA (LBI-HTA) have had an impact on the Austrian healthcare system.Methods: We applied qualitative and quantitative empirical research methods, such as interviewing, download analysis, questionnaire, retrospective routine data analysis, and media analysis. Data were analyzed according to a conceptual framework, considering seven impact categories (awareness, acceptance, process, decision, practice, final outcomes, enlightenment) and different target groups.Results: A rising number of downloads and single HTA reports with high media interest were identified. Interviews showed that HTA reports have increasingly been used for investment and reimbursement decisions, as well as for the preparation of negotiations. Economic impact was indicated by decreased expenditures due to HTA recommendations. Overall, knowledge about evidence-based medicine increased and, in places, an “HTA culture” can be recognized. Yet, several decision-making processes occur at all levels without the use of HTA.Conclusions: The analysis demonstrated an impact within all predefined categories; however, it depends on the system level and its target groups. HTA reports are primarily used by hospital management, (social) insurances, and the Austrian Ministry of Health. Nevertheless, there is still potential to increase the impact of HTA. Therefore, the inclusion of HTA in decision-making processes in Austria needs to move from a voluntary basis to a mandatory one.

Abstract This study examines the impact of peer-to-peer (P2P) file sharing on the Australian theatrical film industry. Using a large data set of torrent downloads observed on three popular P2P networks, we find evidence of a sales displacement effect on box office revenues. However, although statistically significant, the economic significance of this displacement appears relatively small. To establish causality, we make use of the state-day-level panel data structure permitting the use of film fixed effects to help mitigate the endogeneity between film revenues and downloads. To further assist identification, we propose a downloading cost function that considers other states’ downloading activities as a proxy for the number of peers in the download swarm; the US DVD release date as a supply shock to P2P networks; and the substantial structural progression within the Australian internet service provision industry that occurred over the sample period. We observe that the release gap between the US and Australian markets is a key contributor to piracy early in a film’s theatrical life. This finding provides a partial explanation for the industry’s move towards coordinated worldwide releases.

AbstractThe global coronavirus disease 2019 (COVID-19) outbreak has necessitated physical distancing, lockdown, contact tracing, and self-quarantine so as to prevent the spread of the disease. Amid the outbreak, gaming data usage has reportedly increased in the United States, and game download volume has reached a record high in Europe. Because gaming can be used to cope with the psychological stress from the outbreak, therefore mental health professionals should be aware of how increased gaming during the pandemic may contribute to risk of gaming disorder, especially if the pandemic persists. Mental health professionals should thus formulate safe social interaction alternatives for people, particularly adolescents, who have gaming disorder risk.

Full textAbstract:
Massive Open Online Courses (MOOCs) came into the educational ecosystem attracting the attention of the public media, businesses, teachers, and learners from all over the world. The original courses were completely open and free, targeting the worldwide population. However, current MOOC providers have pivoted towards more private directions, and we often find that MOOC materials are completely closed within their hosting platforms and cannot be retrieved from them by their learners. This diminishes the potential of MOOCs by making content available to a small proportion of learners and severely limits the reusability of the educational resources. In this paper, we present a process that we call ‘unMOOCing’, in which we transform the resources of a MOOC into OERs. We taught a MOOC on Open Education in the UNED Abierta platform, and we ‘unMOOCed’ all of its educational resources, making them available to download by the learners that are taking the course. The results of the unMOOCing were very encouraging: the possibility of downloading the course resources was the most highly rated component of the course. Additionally, the two unMOOCed materials that were considered as most useful (presentations and contents in a PDF) were downloaded by 90% of the learners. Now that the majority of MOOC providers are moving towards a more closed educational approach, we believe that this paper sends a powerful message for bringing back the original MOOC concept of ‘Openness’ with the unMOOCing process, thus contributing to the wider dissemination and democratization of education across the globe.

The use of CGNAT at PT. ZYX as a mobile telecommunication service provider cannot be relied as the solution to solve addressing needs against subscriber growth in future technology. Meanwhile, native IPv6 deployment is currently application-driven, which requires maturity support in either subscriber user equipment, network, and application itself. IPv4/IPv6 dual stack deployment was selected by PT. ZYX as stepping stone towards native IPv6 deployment. This paper analyzes the impact of dual stack IPv4/IPv6 deployment for mobile subscribers at PT. ZYX. After selecting the dual stack approach and completing the deployment, test and measurements were performed to confirm the connectivity also against the performance and node utilization to conclude the impact. The test confirmed successful connectivity and the measurements showed that the deployment gives significant enhancement of routing table size and NAT table in node utilization and does not cause performance drop of hop count, throughput, and download time.

Full textAbstract:
Social media influencers have become an important marketing tool for providers of computer applications (apps). We investigated from a trust transfer perspective how the endorsement of a social media influencer (SMI) can improve consumers' app adoption intention, within the framework of the technology acceptance model. Using structural equation modeling, we demonstrated that consumers' trust in an SMI had a direct influence on their trust in an app. Moreover, the endorsement of an SMI increased consumers' trust in the app through the perceived usefulness (but not the ease of use) of the app. Our results also showed that structural assurance, download volume, and online ratings were positively correlated with consumers' trust in the app. Theoretical contributions and managerial implications are discussed.

BackgroundApps can potentially support asthma self-management; however, attracting downloads and encouraging on-going adherence are challenging.ObjectivesWe observed the impact of different recruitment strategies and app features on adoption and continued use.MethodsPractice nurses in five practices in Lothian/Oxford approached adults with active asthma to try out a prototype app. We also advertised the app via social media (Asthma UK; AUK Centre for Applied Research). We observed patients’ download and retention rates and sent pre- and post-trial questionnaires. We sampled 15 patients for interviews before and after using our app for 1 month to explore motivations, triggers and barriers to adoption and usage. Interviews were transcribed and analysed thematically with reference to the Fogg behaviour model.ResultsSocial media attracted 87 users, but only 15 (17%) used the app for 30 days. Practices recruited 24 patients, 13 (54%) continued for 30 days. Successful adoption was dependent on ease of downloading and sufficient motivation. Some patients needed technological assistance with downloading the app and starting to use the features. Adherence was dependent on motivation derived from a sense that the healthcare professional and/or researcher was interested in the results, and that using an app to support their self-management could improve their asthma control.ConclusionSocial media attracted more downloads in a short time. However, most patients stopped using the app within a month. Practices attracted fewer downloads, but patents adhered longer to the app. Dual promotion strategies (social media with practice support) may be the optimal approach to encourage adoption and adherence to telehealth.

Full textAbstract:
A P2P system is composed by autonomous nodes interconnected to share resources. The interconnections between the nodes define the P2P topology that is traversed to lookup resources. As nodes are autonomous, they are free to decide when to arrive and leave and what resources to share and download. To cope with this dynamism, the Evolutionary P2P Networking approach performs a periodical P2P topology reconfiguration applying evolutionary computation and using the amount of successful lookups as the evaluation function that drives the process. We extended this approach to also consider, as a part of the evaluation function, the creation of redundant paths in the topology and, additionally, we introduced elitism to improve the evolutionary process. In this work we present an extensive evaluation of both approaches. The results show that our approach scales better and produces more connected topologies. The improved connectivity ensures a higher rate of successful lookups under static and dynamic scenarios.

Background: Mental health care professionals across the globe should be prepared to contain the spread of COVID-19 among clients with mental illness and should adopt appropriate strategies to manage them effectively. Objective: The objective of this review was to summarize the impact of COVID-19 pandemic on mental health delivery. Methods: A comprehensive literature search was done to identify the effect of COVID-19 global pandemic in mental health delivery. Articles addressing mental health concerns of COVID-19 and its impact on preexisting mental illness and mental health care delivery, available free download in English language were included. A total of nine primary studies published from the onset of COVID-19 until 15th July 2020 were referred to prepare this narrative review. Result: There is evidence that patients with preexisting mental illnesses shows increase in stress, anxiety, sleep disturbances and COVID-19 related delusions and hallucinations during this global pandemic. The proposed drug treatment for COVID-19 and the imposed restrictions on the public to prevent the spread of the disease had resulted in exacerbation of existing mental illness or triggered new mental illness. Conclusion: There should be more research coming up to understand the real effect of COVID-19 on mental health care delivery and possible alternatives to global mental health delivery at the time of global pandemic.

The purpose of this article is to conduct an empirical study to identify the nature of the impact of mergers and acquisitions on Pakistan’s financial sector performance. The research in the article is carried out in the following logical sequence: a thorough literature review on the analysis of key aspects of mergers and acquisitions and their impact on the financial and economic performance of banks before and after their practical implementation; the historical basis of the experience of mergers and acquisitions caused by various economic factors, such as: GDP growth, interest rates on loans, monetary policy; financial analysis of bank profitability, solvency and liquidity indicators before and after the merger and acquisition was conducted. Five commercial banks of Pakistan that were involved in the merger and acquisition processes were selected as the subject of study. The study period is presented before and after the merger and includes two years before the acquisition report and two years after the acquisition announcement by analysis of financial ratios of liquidity, solvency and profitability. The results of empirical and theoretical research have shown that there is a positive relationship between merger and acquisition processes and liquidity ratios of banking institutions; and – the negative impact of such processes on banks’ profitability and solvency in the short term. The author states that the main limitation of the study is the unavailability of financial data until 2006 and the use of a small sample size and a low likelihood of data collection technique, which is limited by a certain type of people and lack of generalization. Keywords: merger, acquisition, bank, solvency risk, liquidity, profitability.

Abstract Post-translational modifications (PTMs) play very important roles in various cell signaling pathways and biological process. Due to PTMs’ extremely important roles, many major PTMs have been studied, while the functional and mechanical characterization of major PTMs is well documented in several databases. However, most currently available databases mainly focus on protein sequences, while the real 3D structures of PTMs have been largely ignored. Therefore, studies of PTMs 3D structural signatures have been severely limited by the deficiency of the data. Here, we develop PRISMOID, a novel publicly available and free 3D structure database for a wide range of PTMs. PRISMOID represents an up-to-date and interactive online knowledge base with specific focus on 3D structural contexts of PTMs sites and mutations that occur on PTMs and in the close proximity of PTM sites with functional impact. The first version of PRISMOID encompasses 17 145 non-redundant modification sites on 3919 related protein 3D structure entries pertaining to 37 different types of PTMs. Our entry web page is organized in a comprehensive manner, including detailed PTM annotation on the 3D structure and biological information in terms of mutations affecting PTMs, secondary structure features and per-residue solvent accessibility features of PTM sites, domain context, predicted natively disordered regions and sequence alignments. In addition, high-definition JavaScript packages are employed to enhance information visualization in PRISMOID. PRISMOID equips a variety of interactive and customizable search options and data browsing functions; these capabilities allow users to access data via keyword, ID and advanced options combination search in an efficient and user-friendly way. A download page is also provided to enable users to download the SQL file, computational structural features and PTM sites’ data. We anticipate PRISMOID will swiftly become an invaluable online resource, assisting both biologists and bioinformaticians to conduct experiments and develop applications supporting discovery efforts in the sequence–structural–functional relationship of PTMs and providing important insight into mutations and PTM sites interaction mechanisms. The PRISMOID database is freely accessible at http://prismoid.erc.monash.edu/. The database and web interface are implemented in MySQL, JSP, JavaScript and HTML with all major browsers supported.

In 1994 a squared two-dimensional barcode was invented by Toyota Company which changed and speed up the concept of tracking and identification. They chose its name QR which stands for Quick Response code. Quick Response codes can convey data such as show a geographical location, make a phone call, link to a simple text, link to a website or template email, access to a portable document format (PDF), display an image, link and download a specific application on a mobile device or Wi-Fi login. Academic journal leaders should notice that QR code as a unique shaped matrix code is increasingly being used by prestigious publishers and scientific journals. But has been ignored by eastern scientific journals and academic institutes for many years. As the author checked all English Iranian journals, no Iranian academic publication or publisher has and uses QR code or even barcode on their websites or on their journal covers till 16 Dec 2019. In this review, the author aimed to explore the use of QR codes specifically for academic publications, identify perceptions towards their use and any information that has been encountered during implementation.

Full textAbstract:
This article probes into how regions organize themselves to deal effectively with the Europe 2020 reform program. More specifically, it maps governance structures of regional policy-making and implementation of Europe 2020 and explains variation in these structures between policy domains and policy stages. The empirical focus is Flanders as this Belgian region possesses substantial legislative and executive autonomy and is therefore highly affected by the Europe 2020 program. The article distinguishes between policy-making (upload) and implementation stages (download) in education, energy and poverty policies. It is hypothesized that the varying impact of Europe 2020 can be attributed to the varying adaptational pressure of EU programs and a set of domestic intervening factors. Findings indicate variation between policy domains and policy stages on a continuum from lead-organization governed networks to shared participant governance networks. Overall, the extent to which Flanders is competent seems to be crucial. In addition, a substantial administrative capacity is needed to firmly steer and coordinate the governance structures that manage Europe 2020 policies. The level of integration further increases the extent to which Flemish Europe 2020 policies are steered.

Computational analysis and modeling of the evolution of trends is an important area of research in Natural Language Processing (NLP) because of its socio-economic impact. However, no large publicly available benchmark for trend detection currently exists, making a comparative evaluation of methods impossible. We remedy this situation by publishing the benchmark TRENDNERT, consisting of a set of gold trends and downtrends and document labels that is available as an unrestricted download, and a large underlying document collection that can also be obtained for free. We propose Mean Average Precision (MAP) as an evaluation measure for trend detection and apply this measure in an investigation of several baselines.

Abstract. Building on psychocognitive theories of information processing, the purpose of this study was to examine the relative impacts of qualitative bandwagon (e.g., using qualitative information such as comments and reviews) and quantitative bandwagon (e.g., using quantitative information such as view and download counts as bandwagon cues) on content selection decisions by media users. An experiment (N = 77) was conducted to investigate the contributions of the two types of bandwagon behaviors to the selections of Hollywood movies online and to identify factors moderating such bandwagon effects. The results showed that cognitive load was negatively associated with the strength of qualitative bandwagon effects, while positively associated with the strength of quantitative bandwagon effects. Although it was marginally significant, the results also showed that the impact of the quantitative bandwagon effect became stronger when individuals were less familiar with Hollywood movies. Implications with respect to tendency for choice imitation, as well as the conceptual understanding of and methodological approach to the bandwagon behaviors in movie selection, are discussed.

This paper examines whether the proliferation of new index products, such as commodity-tracking exchange-traded funds (ETFs), amplified the volatility transmission channel introduced by financialization. This paper focuses on the volatility spillover effects among crude oil, metals, agriculture, and non-energy commodity markets. The results show financialization has an impact on the volatility of commodity prices, predominantly for non-energy commodities. However, the impact on volatility is not symmetric across all commodities. The analysis of index investment and investors’ positions in futures markets shows that, when a relationship exists, it is generally negatively correlated with the realized volatility of non-energy commodities. Using realized volatility in the difference-in-difference model provides estimates that are inconsistent with other findings that non-energy commodities, traded as a part of indices, have experienced higher volatility. The results are similar to the index investment and futures market analysis, where increased participation by investors through new investment products has put download pressure on realized volatility.

Abstract The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic will be remembered as one of the defining events of the 21st century. The rapid global outbreak has had significant impacts on human society and is already responsible for millions of deaths. Understanding and tackling the impact of the virus has required a worldwide mobilisation and coordination of scientific research. The COVID-19 Data Portal (https://www.covid19dataportal.org/) was first released as part of the European COVID-19 Data Platform, on April 20th 2020 to facilitate rapid and open data sharing and analysis, to accelerate global SARS-CoV-2 and COVID-19 research. The COVID-19 Data Portal has fortnightly feature releases to continue to add new data types, search options, visualisations and improvements based on user feedback and research. The open datasets and intuitive suite of search, identification and download services, represent a truly FAIR (Findable, Accessible, Interoperable and Reusable) resource that enables researchers to easily identify and quickly obtain the key datasets needed for their COVID-19 research.

Background As smartphones are now used by most Americans, it is increasingly possible for mental health mobile apps to be disseminated to the general public. However, little is known about how mobile mental health apps are used by the general population outside of a controlled research design. Objective Our objective is to describe how the general population engages with Mindfulness Coach, an iOS- and Android-based app designed to deliver a mindfulness training course. Methods Using anonymous download and analytics data, we characterized the reach, usage, retention, and impact of Mindfulness Coach. We included mobile analytics data from all unique downloads of Mindfulness Coach between August 1, 2018, and April 8, 2019 (N=104,067) as well as starred reviews from all Mindfulness Coach users who provided reviews of the app as of March 1, 2020. Mindfulness characteristics were measured by an in-app assessment using the Five-Facet Mindfulness Questionnaire–Short Form (FFMQ-SF). Results Users engaged, on average, in 4.3 visits to the app (SD 8.8; median 2; 90th percentile 8) and associated with an average total of 49.2 interactions with the app (ie, clicks within the app) (SD 113.8; median 19; 90th percentile 105). Users spent an average of 16.2 minutes (SD 63.1) engaged with the app over the full study time period. There were strong linear effects of app engagement on total FFMQ-SF scores. For example, FFMQ-SF scores were associated with more time spent engaged with the app (R2=.23; P<.001). Mindfulness Coach has been reviewed in the Google Play Store 3415 times, with an average rating of 4.7 out of 5 stars, and over 2000 times in the Apple App Store, with an average rating of 4.8 out of 5 stars. Conclusions These findings suggest that Mindfulness Coach has achieved substantial and sustained reach in the general population; however, it was used less frequently by many downloaders than researchers and designers intended. There was a subpopulation of users who engaged in the app regularly over an extended period of time, and there was a clear relationship between app use and improvements in mindfulness. To strengthen Mindfulness Coach’s public health impact, more research is needed to understand who is using the app and how, and to design strategies to increase user engagement in order for users to receive a larger dose of mindfulness treatment.

Sphingomyelin phosphodiesterase (SMPD1) is a key enzyme in the sphingolipid metabolism. Genetic SMPD1 variants have been related to the Niemann-Pick lysosomal storage disorder, which has different degrees of phenotypic severity ranging from severe symptomatology involving the central nervous system (type A) to milder ones (type B). They have also been linked to neurodegenerative disorders such as Parkinson and Alzheimer. In this paper, we leveraged structural, evolutionary and stability information on SMPD1 to predict and analyze the impact of variants at the molecular level. We developed the SMPD1-ZooM algorithm, which is able to predict with good accuracy whether variants cause Niemann-Pick disease and its phenotypic severity; the predictor is freely available for download. We performed a large-scale analysis of all possible SMPD1 variants, which led us to identify protein regions that are either robust or fragile with respect to amino acid variations, and show the importance of aromatic-involving interactions in SMPD1 function and stability. Our study also revealed a good correlation between SMPD1-ZooM scores and in vitro loss of SMPD1 activity. The understanding of the molecular effects of SMPD1 variants is of crucial importance to improve genetic screening of SMPD1-related disorders and to develop personalized treatments that restore SMPD1 functionality.

This study seeks to reveal the attitudes of the Lithuanian adult population on using digital books and illegally distributed books and seeks to provide possible solutions to Lithuanian publishers and other institutions combating this phenomenon. A quantitative survey of 322 respondents was conducted. The analysis of the results was based on the Technology Acceptance Model, the theory of self-efficacy and the theory of planned behaviour. The results show that the ability to use digital technologies encourages the use of digital books. The perception of digital books as having value reduces the tendency to download them from illegal distribution channels. Legislative regulation does not have a significant impact on the intention not to use digital books from illegal distribution channels. It is likely that a negative assessment of the phenomenon in the immediate environment will have a greater impact on refusing to use illegally distributed books. In order to compete with illegal distribution channels, the channels for legally distributed books need to be more convenient and provide more content.

Abstract Tumor-infiltrating immune cells as integral component of the tumor microenvironment are associated with tumor progress, prognosis and responses to immunotherapy. Genetic variants have been demonstrated to impact tumor-infiltrating, underscoring the heritable character of immune landscape. Therefore, identification of immunity quantitative trait loci (immunQTLs), which evaluate the effect of genetic variants on immune cells infiltration, might present a critical step toward fully understanding the contribution of genetic variants in tumor development. Although emerging studies have demonstrated the determinants of germline variants on immune infiltration, no database has yet been developed to systematically analyze immunQTLs across multiple cancer types. Using genotype data from TCGA database and immune cell fractions estimated by CIBERSORT, we developed a computational pipeline to identify immunQTLs in 33 cancer types. A total of 913 immunQTLs across different cancer types were identified. Among them, 5 immunQTLs are associated with patient overall survival. Furthermore, by integrating immunQTLs with GWAS data, we identified 527 immunQTLs overlapping with known GWAS linkage disequilibrium regions. Finally, we constructed a user-friendly database, CancerImmunityQTL (http://www.cancerimmunityqtl-hust.com/) for users to browse, search and download data of interest. This database provides an informative resource to understand the germline determinants of immune infiltration in human cancer and benefit from personalized cancer immunotherapy.

A traditional Javanese game was one of the cultures inherited of hereditary society which has great value to society, specifically to educate the children. Unfortunately, the impact a lot of modern games in modern era from other countries has demolished the position of local games. It seem gave negative impact for children today. They tend to focus on new game (download new game continuously) in Googleplay store without understanding educative value of it’s game. Consequently the children abandon traditional Javanese game and leave educative game. The researcher aimed to retrofit traditional Javanese games to provide English vocabulary for children in order to motivate them in Learning English. To solve the problem the researcher adapted Kemp and Yalden model of instructional program design to retrofitting Javanese traditional game. The result showed that Javanese traditional games: Learning alphabet was the result retrofitted from Sobyong game, Learning days was the result retrofitted from Engklek game, Learning Colors was the result retrofitted from “Jamuran” game, and Learning part of body was the result retrofitted from "Oyak- Oyakan".

Full textAbstract:
In this work, we develop a general methodology to assess the level of network awareness and friendliness of P2P-TV applications. The methodology is based on a combination of active and passive measurement techniques and can be applied to any P2P-TV system since it is designed to work considering such systems as a black-boxes. As an interesting case study, we then apply this methodology to PPLive, one of the most popular P2P-TV systems nowadays. Focusing on the video content distribution, we consider several per-path and per-peer metrics, investigating which of them mostly biases PPLive download preferences. Furthermore, in order to refine the picture of PPLive peer selection policy, we not only study the impact of different metrics in isolation, but also assess the joint impact of different metrics at the same time. Our main finding is that PPLive seems mainly bandwidth greedy, but does not show any preference toward peer proximity based on RTT delay; at the same time, our results also suggest that this choice alone may provide a nonnegligible level of geographical clustering among peers as a beneficial side effect.

Abstract The impact of broader media choice on political behavior is central to the study of political communication. The availability of high-speed Internet, which allows for high bandwidth media on demand, has given consumers virtually unlimited information choices. Most research assumes that the time spent online is fixed; therefore, broader media choice decreases news consumption, political knowledge, and turnout, especially among the politically uninterested. In this article, I explore another possibility: as Internet quality improves, we spend more time online and consume more information, which subsequently increases knowledge and turnout. To test this possibility, I link geocoded Internet download speed data with survey data. A series of studies indicate that higher quality Internet increases political information search, news consumption, and political knowledge, although perhaps not turnout. This work suggests that our assumption of trade-offs between news consumption and entertainment may need reconsideration.

Background: The field has made significant strides in understanding the mechanisms underlying pediatric sickle cell disease (SCD), and the coming years will likely see the approval of several new medications to treat SCD. The impact of these medications on clinical outcomes, however, will be dependent on patient adherence. Adolescents with SCD are at particular risk for non-adherence, and as disease management increasingly includes self-administration of oral medications, adherence assessment will become a critical component of research on medication effectiveness and clinical care. While electronic monitoring devices (bottles with computer chips that record date- and time-stamps of device openings) such as MEMS® bottles are considered the "gold standard" for adherence assessment in other populations, their feasibility among adolescents with SCD remains unknown. Objectives: The primary aims of this study were to examine data on MEMS® bottle use among adolescents (ages 13-21 years) with SCD to: 1) evaluate the feasibility of MEMS® bottle use; and 2) elicit barriers and facilitators to MEMS® bottle use. Methods: As part of a larger study of a self-management intervention, adolescents were asked to use a MEMS® bottle to store and administer their daily oral medication (hydroxyurea or deferasirox) for the 18-week study duration. The larger study included baseline, post-treatment, and follow-up assessments, at which adolescents were asked to provide their MEMS® bottle for data download. Descriptive statistics were calculated to assess multiple domains of MEMS® bottle feasibility including: initial uptake (% enrolled), MEMS® initiation (% initiated), and MEMS® sustained use (% completed; % provided bottles for download ±2 weeks of scheduled study visit = "on time"). Barriers and facilitators to MEMS® use were elicited via adolescent self-report. Results: In the larger study, 18 non-Hispanic African-American adolescents (M = 17.8 years, SD = 2.6; 61% male) with HbSS were asked to use a MEMS® bottle to store their hydroxyurea (n = 14) or deferasirox (n = 4). Initial uptake was 94.7%, with 18 of 19 eligible adolescents enrolling in the study. Of the 18 enrolled adolescents, all initiated MEMS® use (100%) and 11 sustained MEMS® use through the final study endpoint (61.1%). Eight (44.4%) and 2 (11.1%) adolescents provided their MEMS® bottle for download "on time" at post-treatment (42 days) and follow-up (126 days), respectively. Barriers to MEMS® use included medication changes (i.e., medication holds, dose timing changes) and transitioning from pediatric to adult care. Facilitators included tip sheets (e.g., places to store bottle, reminder to place refills in bottle) and reminder calls. Participants took a median of 26.2% of doses using the MEMS® across the 126 days (SD = 22.4; range 0.79% - 79.3%), illustrating that electronic monitoring devices are not a solution to medication adherence, but are one component of an adherence support strategy. See Figure 1 for adherence rates over time. Discussion: Data suggest that MEMS® are acceptable to adolescents with SCD. Ensuring sustained MEMS® use, however, will likely require additional supports. For example, electronic monitors which automatically transmit data in real-time via Bluetooth or cellular connections would eliminate the need for adolescents to bring bottles to study visits for data downloads. Researchers and clinicians interested in using electronic monitoring devices are encouraged to consider remote monitoring capabilities along with other device features when selecting a product. Larger studies are needed to evaluate concordance between rates of adherence obtained via electronic monitoring and other assessments and to validate electronically-monitored medication adherence with clinically-relevant outcomes for adolescents with SCD.

Abstract Deciphering the biological impacts of millions of single nucleotide variants remains a major challenge. Recent studies suggest that RNA modifications play versatile roles in essential biological mechanisms, and are closely related to the progression of various diseases including multiple cancers. To comprehensively unveil the association between disease-associated variants and their epitranscriptome disturbance, we built RMDisease, a database of genetic variants that can affect RNA modifications. By integrating the prediction results of 18 different RNA modification prediction tools and also 303,426 experimentally-validated RNA modification sites, RMDisease identified a total of 202,307 human SNPs that may affect (add or remove) sites of eight types of RNA modifications (m6A, m5C, m1A, m5U, Ψ, m6Am, m7G and Nm). These include 4,289 disease-associated variants that may imply disease pathogenesis functioning at the epitranscriptome layer. These SNPs were further annotated with essential information such as post-transcriptional regulations (sites for miRNA binding, interaction with RNA-binding proteins and alternative splicing) revealing putative regulatory circuits. A convenient graphical user interface was constructed to support the query, exploration and download of the relevant information. RMDisease should make a useful resource for studying the epitranscriptome impact of genetic variants via multiple RNA modifications with emphasis on their potential disease relevance.

A l’occasion de son 20ème anniversaire, la revue INRA Productions Animales a décidé de publier un numéro spécial sur «20 ans de recherches en productions animales à l’INRA». Son objectif est de retracer, à travers quelques exemples significatifs, des résultats scientifiques majeurs de l’INRA en productions animales, qui ont déjà pour la plupart un impact avéré en élevage. Les avancées spectaculaires de la biologie et des approches systémiques au cours des dernières décennies, tant conceptuelles que méthodologiques, ont eu de très nombreuses répercussions sur les recherches en productions animales, qu’il serait impossible de détailler de façon exhaustive dans le cadre de ce seul numéro. C’est pourquoi nous avons choisi de présenter à grands traits certaines de ces avancées dans cette brève introduction, avant d’en proposer plusieurs illustrations dans les articles de ce numéro. voir le pdf complet à cette adresse https://www6.inrae.fr/productions-animales_eng/content/download/3046/30746/version/1/file/Prod_Anim_2008_21_1_03.pdf

Comme toute activité d’élevage, la production porcine est à l’origine d’effluents qui peuvent avoir un impact sur l’environnement parce qu’ils affectent la qualité de différentes ressources naturelles comme l’air, l’eau, le sol et la santé humaine. Le programme «Porcherie verte» s’est plus particulièrement attaché à un certain nombre de composés présents dans l’alimentation du porc dont une fraction, non retenue par l’animal, est rejetée dans les déjections. Le devenir de ces composés tout au long de la chaîne de production, de l’aliment du bétail au sol, varie beaucoup en fonction des filières utilisées pour la gestion des effluents.
Dans l’esprit du public, les nuisances olfactives sont également très liées à la production porcine. Souvent considérées comme un facteur limitant essentiel au développement de cet élevage, elles dépendent aussi très largement des filières utilisées pour la gestion des effluents.

Peer-to-peer networks (P2Ps) are becoming more and more popular in video content delivery services, such as TV broadcast and Video on Demand (VoD), thanks to their scalability feature. Such characteristic allows for higher numbers of simultaneous users at a given server load and bandwidth with respect to alternative solutions. However, great efforts are still required to study and design reliable and QoS-guaranteed solutions. In this paper, within the scenario of P2P-based VoD services, we study the phenomenon of peer churns and propose four models of the peer behaviour to evaluate its impact on the system performance, which are based on the Gilbert-Elliot chain, the fluidic representation of the user behavior, and a queuing analysis of the system. The models are compared by computing the resources the system has to add on top of the P2P network to satisfy all the download requests. Simulations show important relationships between playback buffer length, peer request rate, peer average lifetime, and server upload rate.

As the digital generations have grown up with high-tech gadgets and become avid users of mobile phones and apps, they are also exposed to increasing mobile security threats and vulnerability. In this paper the authors discuss the impact of recent mobile technology advancements on mobile threat environment and mobile security practices. They also conducted a survey to 262 college students to examine their mobile phone usage patterns, security concerns and practices. The results show that students use their mobile phone frequently for various productivity and entertainment purposes. They are generally aware of and concerned about mobile security, not only on losing the phone physically but also on data theft, web threat, and mobile malware. Students also practice security to some extend - most change PIN and passwords regularly, download their apps mostly from official app stores, and generally keep their OS and apps up-to-date. The authors also found significant correlations between mobile security practices and personal attributes, including major, gender, and technology aptitude.

The circadian rhythm drives the oscillatory expression of thousands of genes across all tissues, coordinating physiological processes. The effect of this rhythm on health has generated increasing interest in discovering genes under circadian control by searching for periodic patterns in transcriptomic time-series experiments. While algorithms for detecting cycling transcripts have advanced, there remains little guidance quantifying the effect of experimental design and analysis choices on cycling detection accuracy. We present TimeTrial, a user-friendly benchmarking framework using both real and synthetic data to investigate cycle detection algorithms’ performance and improve circadian experimental design. Results show that the optimal choice of analysis method depends on the sampling scheme, noise level, and shape of the waveform of interest and provides guidance on the impact of sampling frequency and duration on cycling detection accuracy. The TimeTrial software is freely available for download and may also be accessed through a web interface. By supplying a tool to vary and optimize experimental design considerations, TimeTrial will enhance circadian transcriptomics studies.

With the rapid evolution of the internet, using social media networks such as Twitter, Facebook, and Tumblr, is becoming so common that they have made a great impact on every aspect of human life. Twitter is one of the most popular micro-blogging social media that allow people to share their emotions in short text about variety of topics such as company’s products, people, politics, and services. Analyzing sentiment could be possible as emotions and reviews on different topics are shared every second, which makes social media to become a useful source of information in different fields such as business, politics, applications, and services. Twitter Application Programming Interface (Twitter-API), which is an interface between developers and Twitter, allows them to search for tweets based on the desired keyword using some secret keys and tokens. In this work, Twitter-API used to download the most recent tweets about four keywords, namely, (Trump, Bitcoin, IoT, and Toyota) with a different number of tweets. “Vader” that is a lexicon rule-based method used to categorize downloaded tweets into “Positive” and “Negative” based on their polarity, then the tweets were protected in Mongo database for the next processes. After pre-processing, the hold-out technique was used to split each dataset to 80% as “training-set” and rest 20% “testing-set.” After that, a deep learning-based Document to Vector model was used for feature extraction. To perform the classification task, Radial Bias Function kernel-based support vector machine (SVM) has been used. The accuracy of (RBF-SVM) mainly depends on the value of hyperplane “Soft Margin” penalty “C” and γ “gamma” parameters. The main goal of this work is to select best values for those parameters in order to improve the accuracy of RBF-SVM classifier. The objective of this study is to show the impacts of using four meta-heuristic optimizer algorithms, namely, particle swarm optimizer (PSO), modified PSO (MPSO), grey wolf optimizer (GWO), and hybrid of PSO-GWO in improving SVM classification accuracy by selecting the best values for those parameters. To the best of our knowledge, hybrid PSO-GWO has never been used in SVM optimization. The results show that these optimizers have a significant impact on increasing SVM accuracy. The best accuracy of the model with traditional SVM was 87.885%. After optimization, the highest accuracy obtained with GWO is 91.053% while PSO, hybrid PSO-GWO, and MPSO best accuracies are 90.736%, 90.657%, and 90.557%, respectively.
