In December 1991, immediately after Ukraine declared independence, he participated in a mission to persuade it to return its nuclear weapons to Russia. He describes the thus far unsuccessful effort to dispose of the weapons plutonium that the US and Soviet Union declared excess at the end of the Cold War. The discussion then turns to the US-Russian lab-to-lab program in which the US nuclear-weapon laboratories helped Russia upgrade the security of its plutonium and highly-enriched uranium for the new and more open environment and to… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Over recent decades we have witnessed a growing emphasis on educational quality assurance and evaluation (QAE) around the globe. The trend, not only to intensify evaluative measurements, but also to publish school-specific indicators, has become visible also in the Nordic countries. In Sweden, Denmark and Norway, the governments have launched web-portals, in which various indicators can be observed and compared at the school level. However in Finland, the data is published only at a general level. In this article we compare the discourses of educational experts on comprehensive school QAE policies and practices in four Nordic countries, Sweden, Denmark, Norway and Finland. Our aim is to clarify how the discursive practices reflect the current evaluation and publication policies… Continue Reading →

ABSTRACT The notation for vector analysis has a contentious nineteenth century history, with many different notations describing the same or similar concepts competing for use. While the twentieth century has seen a great deal of unification in vector analysis notation, variation still remains. In this paper, the two primary notations used for expressing the components of a vector are discussed in historical and current context. Popular mathematical texts use the two notations as if they are transparent and interchangeable.… Continue Reading →
