Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Implementation strategy of a data enabled service design process at Ford
No full textThis report describes the development of an implementation strategy for using data in the design process of a design team at the RIC of Ford in Aachen. The implementation strategy consists of a card set and a poster to show contemporary developments in using data in the design process, a service concept, a practical tool kit to start using the data and an organizational implementation roadmap. Throughout the project, a co-creation approach was used by working on one of the commercial vehicle concept projects. This resulted in barriers, enablers and drivers of different approaches for the team. First, I consulted literature on design and data to create an overview of the approaches in this field. I concluded that contemporary approaches use open data such as social platforms to find users expressed thoughts and feelings, or (owned) sensor data to find users functional needs in measurable behaviour. In a case study the insights from literature are visualized in the form of cards to create a tangible artefact for evaluating the different approaches and also act as later reference. This was the first deliverable of this project. The case study resulted in a set of preliminary set of drivers, enablers and barriers for using data. Next, a design intervention was done in the team’s service design project. Together the qualitative insights gathered and analysed. Then I chose parameters for “a behavioural data profile” and designed a service concept based on these parameters. In this service concept behavioural data of the user is used as input for personalized service functionalities. This allows the team to research behaviour and create the foundation for more advanced research. From this step I translated the learned lessons into a final set of barriers, enablers and drivers. This set allows the team to use this specific approach in future projects as well. The main barriers are now defined as: (1) Designers and researchers having different perspectives when setting up research projects resulting in an inability to create the described design concept. (2) There is no clear indication for the design team where and how to use data in the design process. To overcome these barriers a practical tool-kit was designed to allow the team to bridge the gap between the qualitatively gathered data and defining a product-service concept based on a data profile. The value of this practical tool-kit is supported by literature showing the trend towards in-situ research approaches and an evaluation process. The roadmap, the final deliverable of this project, presents directions for applying this approach and presents steps for further organizational implementation. For future research I recommend developing an accessible persona dashboard of the implemented services for Ford to perform easier and more focussed research in the relations between the different sub-functionalities of the vehicle. The practical tool-kit, set of cards and the roadmap help the team in answering their question: “how to use data to better understand our users and their behaviour” by indicating an appropriate approach, an example project and a practical tool-kit.Strategic Product Desig
The impact of jamming and spoofing on GNSS signals
No full textGlobal Navigation Satellite Systems (GNSSs) have become a critical part of the infrastructure of modern society. Radio interference can introduce position or timing errors in systems that use GNSS or, in a worst-case scenario, block the reception of GNSS signals in full. Part of this critical infrastructure is, among others, power plants, banks, and transport. Interference of GNSS signals could originate from nature, such as solar activity or ionospheric effects. Other interference could originate from unintentional sources (e.g., radio signals from a malfunctioning radio tower) or intentional sources such as a jamming or spoofing device. The latter is what this thesis will focus on. This thesis consists of two parts. The first part is about jamming and elaborates on the impact of seven different forms of jamming on two types of GNSS receivers, a time-worn receiver and a cuttingedge receiver. The cutting-edge receiver has as option to turn on Interference Mitigation (IM). The performance of both receivers is the roughly the same in case the IM is turned off on the cutting-edge receiver. However, when the IM is turned on the cutting-edge receiver clearly is more resillient to the jamming signals. In the second part of the thesis various types of spoofing are discussed. Due to time and hardware restrictions it was not possible to perform synchronous spoofing, which is an advanced form of spoofing. Instead, various concepts are discussed that describe how synchronous spoofing could be achieved.Electrical Engineering | Circuits and System
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Seizure preventing MBAN
No full textMany people worldwide suffer from epileptic seizures and not all of them can be prevented using medicines, this thesis is being done for seizure prevention. This is based on implementing a medical body area network (MBAN) that takes sensory recordings across the whole body. This is needed as the research group that proposes this project found from previous research that this is needed for timely seizure prevention. In this report the design, implementation and results of building a prototype MBAN using Bluetooth low energy (BLE) is discussed. The result is a prototype that can measure heart rate when Bluetooth is turned off, but does function with Bluetooth when the heart rate sensor is replaced with mock data. Recommendations are made as to how to resolve the issues that arose during the implementation and as to which topologies should be implemented in the future.MBA
