A Symbiosis between Agile Methods and Knowledge Management for Dealing with Complexity in Software Engineering
No full textThis thesis proceeds from the notion that complexity in the field of software engineering is a result of the internal and external forces that must be brought together to engage in it, resulting in a chaotic state that breeds failure and that this state can be ameliorated through the use of the Agile Methods and knowledge management. After enumerating and discussing the sources of complexity, and surveying the results of their interactions, it proceeds to look at the theory of knowledge management. In elaborating the ideas of Nonaka and Takeuchi we are introduced to the concepts of both the knowledge spiral and a model of knowledge creation, including its enabling conditions and barriers, as well as the concept of Ba. These theories seek to harness the interplay of explicit and tacit knowledge to manage complexity. These theories form a framework that is then applied to the Agile methods, specifically Extreme Programming and the Crystal Clear methodologies, in order to evaluate their values, principles, practices and strategies of software engineering from a knowledge management perspective. This evaluation finds that there is a congruency between the practices of the Agile methods and the theory of knowledge management. In particular the manner in which the Agile methods engage in an iterative pattern of development, its support for direct communication, the incorporation of non-technical team members in defining the product and planning and its reflection on process and product, create a knowledge creating process. As a result, many of the issues of complexity are either removed or minimized through the application of this process.2006-0
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
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
Improving User Profiling for a Richer Personalization: Modeling Context in E-Learning
No full textThis chapter presents the context-aware aspects of ADAPTSUR, a personalization approach designed for e-learning environments. The main features of ADAPTSUR are described and illustrated, showing how to use it to model context and culture for personalization in e-learning environments. The authors describe two materializations of the proposed approach, an adaptive e-learning system and an intelligent tutor, which provide personalized assistance to students taking into account their profiles. Finally, the authors discuss the benefits of their proposal.Fil: Gasparini, Isabela. Universidade Federal do Rio Grande do Sul; BrasilFil: Eyharabide, Maria Victoria.

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
A Generative Artificial Intelligence empowered chatbot : system usability and student teachers’ experience
Full text linkGenerative Artificial Intelligence empowered conversational agents (chatbots) seem to be increasingly used in various settings including education. While student teachers are key stakeholders in supporting and improving educa- tion, not many studies exist in student teachers’ views on the educational use of chatbots. The current study performs a usability evaluation and explores student teachers’ views on the academic use of the VIP-Bot, an advanced academic Discord chatbot, which leverages the OpenAI’s gpt-3.5-turbo-instruct model. Student teachers, within the context of the formative task of writing a literature review, interacted with the chatbot and self-reported their experiences through an online survey. The usability evaluation returned a relatively high SUS score (76.36) for the chatbot. Moreover, student teachers view on the chatbot acceptance, effectiveness and motivation were positive. The chatbot can be helpful in developing ideas and initiating further engagement with the literature. Academic misconduct concerns have been expressed if the chatbot is not used properly. The study, as a usability evaluation, is an essential step in further chat- bot development and, as an investigation of student teachers’ views, it is an essential step on the chatbot employment in teaching and learning
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
