Business Oriented Service Level Management (BOSELM)
No full textWith the growing pervasiveness of information technology (IT), the quality of the information services is crucial for companies. The effectiveness of the IT department is in fact a function of the "quality of service" (QoS), expressed as availability, response time, and similar variables. The ultimate quality of service, that is in fact the business operations result (business outcome) perceived by the business user, is linked to IT QoS by a cause-effect chain. Our research proposes a comprehensive methodology for the Service Level Management (SLM), which includes an architectural model of and the steps necessary to implement it within enterprises. The main purpose is to provide a method for managing the relationship between business-IT performances, by considering: (a) business-IT linkage model, (b) technology architecture, (c) organizatio
Forecasting in multi-skill call centers.A Multi-agent Multi-service (MAMS) Approach: Research in Progress
Full text linkWorkforce management is critical in call center business. Human resources are the highest cost, and therefore efficiency is a key success factor. On the other side relevant peaks of incoming calls have to be served. We here consider a complex case, with a many-to-many relationship between agents and services, i.e. the same agent serves many customers and the same customer may be served by many agents. In this perspective, we propose a model to forecast calls in long- and mid-term by ARIMA (Auto-Regressive Integrated Moving Average), and to size workforce in mid-term by integrating an Erlang model. Finally, we have developed a tool to forecast calls in a multi-agent multi-service call center. Field tests are running and first results validate our model
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
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
