Software cost estimation in the Netherlands : 10 years later
No full textIn 1988 a Dutch large scale survey on the state of the art in practice of software cost estimation and control showed disappointing results. The survey was repeated in 1998. Since then, additional research has resulted in more consensus what good practices in the area mean. In 1998 a comparable survey has been carried out with the intend of finding out if these good practices have been adopted in practice and to see if this resulted in better estimations. The result of this survey is presented in this paper
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
Test point analysis : a method for test estimation
No full textThis document describes the test estimate preparation technique known as test point
analysis (TPA®I). TPA can be used 10 objectively prepare an estimate for a System test or
acceptance test. TPA covers only so-called black-box testing; an estimate for the test
activities. which precede black-box testing (i.e. white-box lesling), wilt already have been
included in the estimale produced by function point analysis. So, while the function point
analysis productivity factor covers the while-box testing, it does not cover system testing or
acceptance testing.
TPA can also be used if the test hour allowance has been predetermined. By performing a
TPA, any risks involved can be clearly identified by comparing the objective TPA estimate
with the predetermined number of test hours. With TPA, it is also possible to determine or
calculate the relative importance of the various functions, with a view to using the available
testing time as efficiently as possible
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
