abstract this study examines the relationship between reading anxiety and difficulty of texts as well as the relationship between reading anxiety and students perceived difficulty of the texts. since difficulty is a relative concept, i limited its definition by sticking to the readability formula. we also took students perceived difficulty levels into account. therefore, in the present study, ...
What is the point of university? In the modern state, we are faced with a plethora of competing and sometimes contradictory answers to this question. To some extent, the answer depends on who is paying, which differs considerably between countries. At one extreme, the Nordic countries continue to fund higher education almost entirely from general taxation. At the other, private institutions in ...
Why do we age? Since ageing is a near-universal feature of complex organisms, a convincing theory must provide a robust evolutionary explanation for its ubiquity. This theory should be compatible with the physiological evidence that ageing is largely due to deterioration, which is, in principle, reversible through repair. Moreover, this theory should also explain why natural selection has favou...

section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a “memex” that Vannevar Bush proposed in his seminal article, “As We May Think.” Faceted search plays a key role in this program. Faceted search a...
This article – written in honour of Jürgen Ehlers – consists of two different, though interlocking parts: Section 1 describes my 54 years of perpetual experiences and exchanges with him, both science and episodes, whilst section 2 describes the history of astrophysical black holes, which evolved during the same epoque though largely independently, with its activity centers in other places of th...
We study a hard geometric problem. Given n points in the plane and a positive integer k, the Rectilinear k-Bends Traveling Salesman Problem asks if there is a piecewise linear tour through the n points with at most k bends where every line-segment in the path is either horizontal or vertical. The problem has applications in VLSI design. We prove that this problem belongs to the class FPT (fixed...
What shall we do when we have done everything we could for the diagnosis and treatment of a patient, but were not successful? What shall we do when there is no definite treatment for a patient? What shall we do when we have no diagnosis or treatment for a patient? Some useful suggestions are presented here to get rid of these situations.
How Science Works’ is now the focus of the national science specifications in English schools. This article is a brief introduction to the philosophy of science from the Greeks to the present day that underpins this notion. From September 2006, the emphasis for teaching science at GCSE is on ‘How Science Works’. This focus will also shape the revisions of the AS and A2 specifications from Septe...
