One essential component in the construction of patent landscapes in biomedical research and development (R&D) is identifying the most seminal patents. Hitherto, the identification of seminal patents required subject matter experts within biomedical areas. In this article, we report an analytical method and tool, Patent Citation Spectroscopy (PCS), for the online identification of landmark patents in user-specified areas of biomedical innovation. Using USPTO data, PCS mines the cited references within large sets of patents at the internet and provides an estimate of the historically most impactful prior work. We show the efficacy of PCS in three case studies of biomedical innovation with clinical relevance: (1) RNA interference (RNAi), (2) cholesterol and (3) cloning. PCS mined and analyzed cited references related to patents on RNA interference and correctly identified the foundational patent of this technology, as independently reported by subject matter experts on RNAi intellectual property. Secondly, we apply PCS to a broad set of patents dealing with cholesterol – a case study chosen to reflect a more general, as opposed to expert, patent search query. PCS mined through cited references and identified the seminal patent as that for Lipitor, the groundbreaking medication for treating high cholesterol as well as the pair of patents underlying Repatha. The final case study, cloning, highlights some of the advantages conferred by the PCS methodology in identifying seminal patents. These cases suggest that PCS provides a useful method for identifying seminal patents in areas of biomedical innovation and therapeutics. The interactive tool is free-to-use at: http://www.leydesdorff.net/comins/pcs/index.html. 相似文献

This article explores the process of developing online tutorials for a specified student group, in this case Second-Year Nursing students in University College Dublin. The product was commissioned by the Health Sciences Library and the UCD School of Nursing, Midwifery, and Health Systems. It was developed as a “Capstone Project” for part fulfillment of the MLIS in UCD. We focused our research on three areas of scholarship to assist in the development of our product, namely Information Behavior, Learning Technologies, and Learning Science and Design. Flemings VARK model was used to inform the team of the four different learning styles (visual, auditory, reading, and kinesthetic) and to match the presentation style to these. An initial difficulty in the assessment phase was one of access to a large group of students, as the students were on clinical placements. We created personas and a profile of nursing students to try and compensate for this. The tutorial was developed to cater for this specific group of students and later to act as a valuable support to the Library, which is under severe pressure in terms of staff availability to support student learning. The product is relatively straightforward to produce (and maintain) and is something the Library will be able to develop and add to in future years. 相似文献

The pervasive use of multiple technological tools to engage with media and political content (i.e., TV sets, laptops, tablets, smartphones, etc.) has deeply altered the way citizens around the world consume information and discuss public affair issues. Many are using 2, or even several “screens” at the same time to do so, a phenomenon known as second or dual screening. The goal of this article is twofold. First, it introduces a set of novel studies published as a special section devoted to second screening. Second, based on nationally representative original survey data collected in twenty societies (N = 22.033), the study depicts a snapshot of second screening habits for news and politics around the world. Findings reveal that young people tend to second screen more than older counterparts. Similarly, there are also differences in political behaviors between groups of high and low frequency second screen users. More intensive users tend to politically express themselves in social media, and participate more often in offline political activities. On the other hand, results indicate little or no differences between these two groups in terms of their voting behavior. 相似文献

Abstract As the wealth of business information on the Internet increases, the development of online tools to assist patrons in effectively utilizing the information will become critical. Because the Internet provides information and delivers it, it offers significant opportunities for teaching interactive research strategies at anytime, day or night, and from anywhere patrons have an Internet connection. This paper discusses the design of a step-by-step, interactive tutorial on researching companies online ( http://home.sprintmail.com/～debflanagan/index.html) and provides tips and techniques for developing similar tutorials for the Web. 相似文献

As U.S. news outlets grapple with the challenges of delivering news in a digital era, journalists cover elections with tighter deadlines and fewer resources. Consequently, we are seeing an explosion in coverage of polls, which require little original reporting and attract readers through their “horse race” appeal. As the number of polls increases, news professionals are culling data from a wider spectrum of sources that vary in methodology and credibility. What remains unclear is how effective the news media are in providing polling context in their online coverage that is less limited by the space and time constraints of more traditional mediums. Utilizing the 2016 U.S. primaries, this exploratory study examines online news articles focused on polls to evaluate the quality of digital coverage across national news outlets.

ABSTRACT As the online public library becomes a creation of the Internet, will taxpayers continue to support an institution that is potentially “just another address”? And will the public library have to compete in the image and likeness of Barnes and Noble.com? 相似文献

Courses: Disaster Day (DD) is a single-class activity designed for public speaking classrooms, but could also be applied to courses addressing small group communication. Objectives: DD integrates fundamental skills of the basic speech course, fosters participation through group work, and introduces new concepts and skills. By the end of the activity, students should be able to (1) display fundamental speech skills by researching a topic quickly, organizing an informative speech, and delivering a presentation; (2) function effectively in a group by working cooperatively on a project with a tight deadline; and (3) understand basic elements of upcoming skills by creating an informative and visually appealing presentation for a mass audience before having visual aid instruction. DD has similar learning objectives to activities occurring later in the term (i.e., graded speeches) in order to introduce the students to expectations of future, more advanced assignments. As such, I do not treat DD as a graded activity, but rather a fun, low-risk, and useful practice opportunity. 相似文献

The Portal to Texas History ( http://texashistory.unt.edu) and the University of North Texas (UNT) Digital Library ( http://digital.library.unt.edu) contain more than 445,000 items collectively, hosted by the UNT Libraries. These collections include a variety of serial publications such as newsletters, magazines, scholarly journals, annual reports, and yearbooks. Many of these serials are key resources for the user groups of both repositories. In this article, we discuss the importance of serials within our collections, some of the challenges, the standards we use, and how we leverage metadata to facilitate access to serials for diverse global users. 相似文献

ABSTRACT This article discusses the transition that publishers have had to make in the process of converting print journals and reference books to an online format. It was originally thought that making content available online would save publishing costs, but the changes made to production cycles and the needs of making content widely available, updated, and housed on online platforms are sometimes more expensive than the print process alone. Publishers have responded with new pricing models, and they are working more closely with libraries to deliver content to a wider audience while competing with search engines and other online content providers. Additionally, publishers have a new responsibility to manage the quality and accuracy of content given that so much information is now available to readers. This article originally published in Journal of Library Administration, Vol. 49, Issue 4, pages 439–458, 2009. doi: http://dx.doi.org/10.1080/01930820902832579. 相似文献

Column Editor's Note. As the Column Title indicates, this column brings Global Perspectives to the Journal of Library Administration. Library administrators in different types of libraries share case studies, research, reports, or articles from a wide variety of geographic locations outside of North America. Prospective authors are invited to discuss possible future contributions with the column editor at: Jim.Agee@yahoo.com. The article presents the project Spatial Analysis of the public library network in Slovenia; the approach, related work, methods used, main findings, impacts, and transferability to other environments. The network of public libraries in Slovenia is quite well developed and consists of slightly over 1,000 service points, i.e., local libraries, their external service points, and bookmobile stops. Public libraries are one of the pillars that preserve the Slovenian language and enhance the local social life. The travel distance to the nearest library is highly important, even more when taking into account social gatherings, access to online databases, and participation in educational and other meetings. Spatial analysis has been performed by using the methods of geographical information systems. A part of the project is also the development of a lightweight Web geodatabase/geoprocessing tool for the planning of library services. Library administrators could directly and easily use the tool for daily and strategic planning to analyze in detail the spatial level of the sociodemographic characteristics of the potential users in the vicinity. The findings have shown significant differences among regions, recommended improvements of the library network, suggested the refinement of the role of the library services according to the perceived needs of the local people, and confirmed the importance of the mobile libraries for rural and remote areas. 相似文献

Objective:This study was intended to (1) provide clinical trial data-sharing platform designers with insight into users'' experiences when attempting to evaluate and access datasets, (2) spark conversations about improving the transparency and discoverability of clinical trial data, and (3) provide a partial view of the current information-sharing landscape for clinical trials. Methods:We evaluated preview information provided for 10 datasets in each of 7 clinical trial data-sharing platforms between February and April 2019. Specifically, we evaluated the platforms in terms of the extent to which we found (1) preview information about the dataset, (2) trial information on ClinicalTrials.gov and other external websites, and (3) evidence of the existence of trial protocols and data dictionaries. Results:All seven platforms provided data previews. Three platforms provided information on data file format (e.g., CSV, SAS file). Three allowed batch downloads of datasets (i.e., downloading multiple datasets with a single request), whereas four required separate requests for each dataset. All but one platform linked to ClinicalTrials.gov records, but only one platform had ClinicalTrails.gov records that linked back to the platform. Three platforms consistently linked to external websites and primary publications. Four platforms provided evidence of the presence of a protocol, and six platforms provided evidence of the presence of data dictionaries. Conclusions:More work is needed to improve the discoverability, transparency, and utility of information on clinical trial data-sharing platforms. Increasing the amount of dataset preview information available to users could considerably improve the discoverability and utility of clinical trial data. 相似文献
