Rede Wageningen

Ebifananyi at The Uganda Museum, an exhibition relating to my doctoral research, following up on an earlier exhibition in Antwerp, Belgium and in Kampala part of KLAART18, a ‘public art festival which celebrates public art for and in the city’. The visitors of the show in Antwerp were welcomed with a letter from co-curators of the exhibition Bas Vroege and Joachim Naudts. Here they were welcomed by me: Dear Visitor, You are most welcome to a temporary exhibition about photographs. ‘Ebifananyi’, the Luganda word that is used to signify photographs as well as other likenesses, gives you the opportunity to see a variety of historical photographs made in Uganda. It also invites you to reflect on what you see. In 2011 Canon Griffin and I set up History In Progress Uganda, a platform that digitizes and shares historical photographs. With the help of numerous Ugandan photographers, history enthusiasts and artists I produced eight books with the same title of the exhibition. Each book presents a collection of historical photographs and contemporary responses to it. Last year an exhibition took place in FoMu, the photo museum in Antwerp, Belgium. It presented the content of these books to the Belgian audience. The conditions of this museum cannot be reproduced in Uganda. We here present to you both two- and three dimensional documentation of that show. Photographs are always made from a particular viewpoint and the way they look depends on the technology that was available to the photographer. It is not unusual for photographs to show what someone wants someone else to see rather than to be neutral documentation. They can be used as tools of identification and to estrange people from each other. It is my hope that the photographs that were added to the permanent museum display will make you wonder, cause recognition, show beauty and give you a valuable experience, Andrea Stultiens [See]

Cultural heritage institutes often make use of tags to facilitate searching their collections. While professionals associated with these institutes are able to add high quality descriptions to objects in the collections, both their time and their areas of expertise are limited. As a result, online tagging by non-professional users is more frequently becoming deployed to increase the number of tags. When these users are asked to tag objects in the collection, they can be confronted with tags submitted by other users. These tags may be of varying quality and present in differing numbers, both of which may influence users' tagging behavior. We report on a study on the impact of presenting different types of tags on the quality and quantity of tags added by users. We conclude that there is no difference in the quality and quantity of added tags in all experimental conditions, with the exception of the condition in which incorrect tags were presented. In this condition, the quality of the tags added by users decreased. We discuss the implications of these findings on the design of tagging interfaces.

The early history of leukemia reaches back 200 years. In 1811, Peter Cullen defined a case of splenitis acutus with unexplainable milky blood. Alfred Velpeau defined the leukemia associated symptoms, and observed pus in the blood vessels (1825). Alfred Donne detected a maturation arrest of the white blood cells (1844). John Bennett named the disease leucocythemia, based on the microscopic accumulation of purulent leucocytes (1845). That same year, Rudolf Virchow defined a reversed white and red blood cell balance. He introduced the disease as leukamie in 1847. Henry Fuller performed the first microscopic diagnose of a leukemic patient during life (1846). This gradual process brought us towards our current understanding of this complex disease. (C) 2011 Elsevier Ltd. All rights reserved.

The author of this meticulously researched work surveys the possibilities of functional analysis of shell implements. Her study of shell tools, as well as flint and stone tools, from the pre-Columbian sites of Anse à la Gourde and Morel, Guadeloupe draws on archaeological, ethnographical,ethnohistorical and experimental data.The results of the functional analysis of all artifact categories are presented, as well as a reconstruction of the technological system in the pre-Columbian period. She demonstrates the value of this integral approach in shedding light on the choices made in the past on tool use and the utilisation of different raw materials

This is part 4 of the Rchon statistics course. It continues the basics of statistical testing in R. In this tutorial, we will treat the following statistical testing methods: Mann-Whitney test Kruskal-Wallis test Kolmogorov-Smirnov test Follow the instructions in Instructions Tutorial 4.pdf to start the tutorial.

Increasingly code and algorithms are techniques also applied in textual scholarship, giving rise to new interactions between software engineers and textual scholars. This book argues that much of that process and its effects on textual scholarship are still poorly understood and go unchecked by otherwise normal processes of quality control in scholarship such as peer review. The text provides case studies in which some of these interactions become more apparent, as well as the academic challenges and problems that they introduce. The book demonstrates that the space between code creation and conventional scholarship is one that offers many affordances to textual scholarship that until now remain unexplored. The author argues that it is an intellectual obligation of programmers and textual scholars to examine the properties of digital text and how its existence changes and challenges textual scholarship.
