Disseminating research with web CV hyperlinks

This is an accepted manuscript of an article published by John Wiley & Sons Ltd in Journal of the Association for Information Science and Technology on 03/07/2014, available online: https://doi.org/10.1002/asi.23070 The accepted version of the publication may differ from the final published version.Some curricula vitae (web CVs) of academics on the web, including homepages and publication lists, link to open‐access (OA) articles, resources, abstracts in publishers' websites, or academic discussions, helping to disseminate research. To assess how common such practices are and whether they vary by discipline, gender, and country, the authors conducted a large‐scale e‐mail survey of astronomy and astrophysics, public health, environmental engineering, and philosophy across 15 European countries and analyzed hyperlinks from web CVs of academics. About 60% of the 2,154 survey responses reported having a web CV or something similar, and there were differences between disciplines, genders, and countries. A follow‐up outlink analysis of 2,700 web CVs found that a third had at least one outlink to an OA target, typically a public eprint archive or an individual self‐archived file. This proportion was considerably higher in astronomy (48%) and philosophy (37%) than in environmental engineering (29%) and public health (21%). There were also differences in linking to publishers' websites, resources, and discussions. Perhaps most important, however, the amount of linking to OA publications seems to be much lower than allowed by publishers and journals, suggesting that many opportunities for disseminating full‐text research online are being missed, especially in disciplines without established repositories. Moreover, few academics seem to be exploiting their CVs to link to discussions, resources, or article abstracts, which seems to be another missed opportunity for publicizing research

People-search : searching for people sharing similar interests from the web

On the Web, there are limited ways of finding people sharing similar interests or background with a given person. The current methods, such as using regular search engines, are either ineffective or time consuming. In this work, a new approach for searching people sharing similar interests from the Web, called People-Search, is presented. Given a person, to find similar people from the Web, there are two major research issues: person representation and matching persons. In this study, a person representation method which uses a person\u27s website to represent this person\u27s interest and background is proposed. The design of matching process takes person representation into consideration to allow the same representation to be used when composing the query, which is also a personal website. Based on this person representation method, the main proposed algorithm integrates textual content and hyperlink information of all the pages belonging to a personal website to represent a person and match persons. Other algorithms, based on different combinations of content, inlink, and outlink information of an entire personal website or only the main page, are also explored and compared to the main proposed algorithm. Two kinds of evaluations were conducted. In the automatic evaluation, precision, recall, F and Kruskal-Goodman F measures were used to compare these algorithms. In the human evaluation, the effectiveness of the main proposed algorithm and two other important ones were evaluated by human subjects. Results from both evaluations show that the People-Search algorithm integrating content and link information of all pages belonging to a personal website outperformed all other algorithms in finding similar people from the Web

PhysarumSpreader: a new bio-Inspired methodology for identifying influential spreaders in complex networks

Identifying influential spreaders in networks, which contributes to optimizing the use of available resources and efficient spreading of information, is of great theoretical significance and practical value. A random-walk-based algorithm LeaderRank has been shown as an effective and efficient method in recognizing leaders in social network, which even outperforms the well-known PageRank method. As LeaderRank is initially developed for binary directed networks, further extensions should be studied in weighted networks. In this paper, a generalized algorithm PhysarumSpreader is proposed by combining LeaderRank with a positive feedback mechanism inspired from an amoeboid organism called Physarum Polycephalum. By taking edge weights into consideration and adding the positive feedback mechanism, PhysarumSpreader is applicable in both directed and undirected networks with weights. By taking two real networks for examples, the effectiveness of the proposed method is demonstrated by comparing with other standard centrality measures

From Microsound to Vaporwave:internet-mediated musics, online methods, and genre

How is the internet transforming musical practices? In this article, through a study of five prominent popular and crossover music genres spanning the period from the late 1990s to the present, we examine how the internet has augmented the creative, aesthetic, communicative and social dimensions of music. Analysing the internet-based practices associated with these genres poses methodological and theoretical challenges. It requires new research tools attentive to the online practices involved in their creation and reception. To this end we adapt the Issue Crawler software, an established digital method that analyses networks of hyperlinking on the world-wide web. In addition, it requires a theoretical framework that can respond to music’s profuse mediations in the digital environment. We propose that a version of genre theory offers such a framework. The paper concludes by reflecting on the implications of our analysis for theorising music and place and for historical periodization after the internet

SdrLift: A Domain-Specific Intermediate Hardware Synthesis Framework for Prototyping Software-Defined Radios

Modern design of Software-Defined Radio (SDR) applications is based on Field Programmable Gate Arrays (FPGA) due to their ability to be configured into solution architectures that are well suited to domain-specific problems while achieving the best trade-off between performance, power, area, and flexibility. FPGAs are well known for rich computational resources, which traditionally include logic, register, and routing resources. The increased technological advances have seen FPGAs incorporating more complex components that comprise sophisticated memory blocks, Digital Signal Processing (DSP) blocks, and high-speed interfacing to Gigabit Ethernet (GbE) and Peripheral Component Interconnect Express (PCIe) bus. Gateware for programming FPGAs is described at a lowlevel of design abstraction using Register Transfer Language (RTL), typically using either VHSIC-HDL (VHDL) or Verilog code. In practice, the low-level description languages have a very steep learning curve, provide low productivity for hardware designers and lack readily available open-source library support for fundamental designs, and consequently limit the design to only hardware experts. These limitations have led to the adoption of High-Level Synthesis (HLS) tools that raise design abstraction using syntax, semantics, and software development notations that are well-known to most software developers. However, while HLS has made programming of FPGAs more accessible and can increase the productivity of design, they are still not widely adopted in the design community due to the low-level skills that are still required to produce efficient designs. Additionally, the resultant RTL code from HLS tools is often difficult to decipher, modify and optimize due to the functionality and micro-architecture that are coupled together in a single High-Level Language (HLL). In order to alleviate these problems, Domain-Specific Languages (DSL) have been introduced to capture algorithms at a high level of abstraction with more expressive power and providing domain-specific optimizations that factor in new transformations and the trade-off between resource utilization and system performance. The problem of existing DSLs is that they are designed around imperative languages with an instruction sequence that does not match the hardware structure and intrinsics, leading to hardware designs with system properties that are unconformable to the high-level specifications and constraints. The aim of this thesis is, therefore, to design and implement an intermediatelevel framework namely SdrLift for use in high-level rapid prototyping of SDR applications that are based on an FPGA. The SdrLift input is a HLL developed using functional language constructs and design patterns that specify the structural behavior of the application design. The functionality of the SdrLift language is two-fold, first, it can be used directly by a designer to develop the SDR applications, secondly, it can be used as the Intermediate Representation (IR) step that is generated by a higher-level language or a DSL. The SdrLift compiler uses the dataflow graph as an IR to structurally represent the accelerator micro-architecture in which the components correspond to the fine-level and coarse-level Hardware blocks (HW Block) which are either auto-synthesized or integrated from existing reusable Intellectual Property (IP) core libraries. Another IR is in the form of a dataflow model and it is used for composition and global interconnection of the HW Blocks while making efficient interfacing decisions in an attempt to satisfy speed and resource usage objectives. Moreover, the dataflow model provides rules and properties that will be used to provide a theoretical framework that formally analyzes the characteristics of SDR applications (i.e. the throughput, sample rate, latency, and buffer size among other factors). Using both the directed graph flow (DFG) and the dataflow model in the SdrLift compiler provides two benefits: an abstraction of the microarchitecture from the high-level algorithm specifications and also decoupling of the microarchitecture from the low-level RTL implementation. Following the IR creation and model analyses is the VHDL code generation which employs the low-level optimizations that ensure optimal hardware design results. The code generation process per forms analysis to ensure the resultant hardware system conforms to the high-level design specifications and constraints. SdrLift is evaluated by developing representative SDR case studies, in which the VHDL code for eight different SDR applications is generated. The experimental results show that SdrLift achieves the desired performance and flexibility, while also conserving the hardware resources utilized

Issue Mapping for an Ageing Europe

Issue Mapping for an Ageing Europe is a seminal guide to mapping social and political issues with digital methods. The issue at stake concerns the imminent crisis of an ageing Europe and its impact on the contemporary welfare state. The book brings together three leading approaches to issue mapping: Bruno Latour's social cartography, Ulrich Beck's risk cartography and Jeremy Crampton's critical neo-cartography. These modes of inquiry are put into practice with digital methods for mapping the ageing agenda, including debates surrounding so-called 'old age', cultural philosophies of ageing, itinerant care workers, not to mention European anti-ageing cuisine. Issue Mapping for an Ageing Europe addresses an urgent social issue with new media research tools

Identifying institutional relationships in a geographically distributed public health system using interlinking and co-authorship methods

The final publication is available at Springer via http://dx.doi.org/ 10.1007/s11192-016-1839-zLink analysis is highly effective in detecting relationships between different institutions, relationships that are stronger the greater their geographical proximity. We therefore decided to apply an interlinking analysis to a set of geographically dispersed research entities and to compare the results with the co-authorship patterns between these institutions in order to determine how, and if, these two techniques might reveal complementary insights. We set out to study the specific sector of public health in Spain, a country with a high degree of regional autonomy. We recorded all Spanish health entities (and their corresponding URLs) that belong to, and were hyperlinked from, the national government or any of the regional governments, gathering a total of 263 URLs. After considering their suitability for web metric analysis, interlinking scores between all valid URLs were obtained. In addition, the number of co-authored articles by each pair of institutions and the total scientific output per institution were retrieved from Scopus. Both interlinking and co-authorship methods detect the existence of strength subnets of geographically distributed nodes (especially the Catalan entities) as well as their high connectivity with the main national network nodes (subnet of nodes distributed according to dependence on national government, in this case Spain). However, the resulting interlinking pattern shows a low but significant correlation (r = 0.5) with scientific co-authorship patterns. The existence of institutions that are strongly interlinked but with limited scientific collaboration (and vice versa) reveals that links within this network are not accurately reflecting existing scientific collaborations, due to inconsistent web content development.Ontalba Ruipérez, JA.; Orduña Malea, E.; Alonso-Arroyo, A.

Patterns of Web Linking to Heterogeneous Groups of Companies: The Case of Stock Exchange Indexes

Purpose – To extend co-link analysis to Websites of heterogeneous companies belonging to different industries and countries. To cluster companies by industries and compare results from different countries. Design/methodology/approach – Websites of 255 companies that belong to five stock exchange indexes were included in the study. Data on co-links pointing to these Websites were gathered using Yahoo!. Co-link data were analyzed using multidimensional scaling (MDS) to generate MDS maps that would position companies based on their co-link counts. Findings –Comparisons of results across different countries and economies showed the following overall pattern: companies whose businesses are information based tend for form well defined clusters while companies operating on a more traditional business model tend not to form clear groups. A comparison between EU zone and the U.S. suggests that the EU economy is not well integrated yet. Practical implications – Findings from the study suggest the possibility of using co-link analysis to distinguish the information based industries from traditional industries. Originality/value –Extended co-link analysis from a single industry to heterogeneous industries with global and complex business phenomena
