Puzzling history – the personal file in residential care: a source for life history and historical research

Since the turn of the century large groups of former institutionalised children have exercised their right to see their ‘personal files’, and this has drawn widespread attention to these documents and their potential in scholarly research. This article explores the meanings of personal files from the period 1945–1984 as sources for both historical researchers and adult care leavers themselves, in the context of the orphanages in Ghent, Belgium. Based on the experiences of those who have consulted their files, we come to the conclusion that the personal files of the Ghent orphans provide some new information but, at the same time, leave a lot of issues unresolved. Although the files offered significant insights for researchers studying the most recent period in the history of the Ghent orphanages, it is difficult to see them as ‘keys to the past’ for former orphans who are trying to (re)construct their own, individual life histories.     

Globalization and the freedom of knowledge

This article considers the transmission of knowledge in higher education. It takes the metaphor of the music industry that pre‐selects the music people can buy. The sales potential is the leading principle in the selection process. Often the small producer is excluded because his or her music is not of commercial interest. The end‐customer does not know what he or she is missing because he or she has never heard the music. It is to be feared that a similar market principle will also influence the selection of knowledge and affect the capacity of higher education institutions to freely generate and transmit new knowledge. The globalization of higher education risks homogenizing the cultural traditions of the non‐Western world through a process of Western cultural domination. On the other hand, the Internet, via open source software like LINUX, might serve to democratize higher education and allow greater grassroots input.

Training complete engineers: Global enterprise and engineering education

For the past few years a discussion has been going on about the specific skills and knowledge a complete engineer should possess. Apart form this discussion, a separate debate has focused on the content of an engineer's education. This article is a combination of two joint papers (De Graaff and Ravesteijn 2000, Ravesteijn and De Graaff 2000) bearing on these respective subjects, presented by the authors at the SEFI 2000 conference in Paris. The demands from industry that engineers of the future will have to meet are summarized and related to characteristics of modern training methods. It is argued that a new view on the content of the engineer's education implies, at least to a certain extent, a new set of educational tools.

一矩阵方程组的反射解

We derive necessary and sufficient conditions for the existence and an expression of the （anti）reflexive solution with respect to the nontrivial generalized reflection matrix P to the system of complex matrix equations AX = B and XC = D. The explicit solutions of the approximation problem min x∈Ф ｜｜X - E｜｜F was given, where E is a given complex matrix and Ф is the set of all reflexive （or antireflexive） solutions of the system mentioned above, and ｜｜·｜｜ is the Frobenius norm. Furthermore, it was pointed that some results in a recent paper are special cases of this paper.
