– Introductory programming courses entail students' high failure and dropout rates. In an effort to tackle this problem, we carried out a qualitative study aiming to shed some light on the programming phase that is most challenging for students, in order to elicit the specific difficulties they experience while learning to program. In doing so, distinctive(More)
The introductory undergraduate course on Algorithms and Computer Programming, commonly known as CS1, has always presented a challenge when considering student failure and drop out rates. Despite this, it is acknowledged that this is a foundational course for a large part of the CS curriculum. In this paper we present the results of a project that combines(More)
Today, users need pro-active information recovery mechanisms that can rapidly obtain the largest amount of relevant information possible. Several information recovery systems are available, but they still have semantic problems related to document treatment and retrieval. The proposed system uses statistical text-mining techniques to semantically associate(More)
We report the results of cytogenetic, fluorescence in situ hybridization (FISH) and molecular analyses in a 15-year-old boy diagnosed with acute myeloid leukemia subtype M2 (AML-M2). Cytogenetic and FISH analyses, the latter with whole chromosome painting probes, revealed a complex translocation involving four chromosomes: t(8;17;15;21)(q22;q23;q15;q22).(More)
Translocations involving the short arm of chromosome 12 are frequent events among patients with various hematologic malignancies. In approximately half of these patients, fluorescence in situ hybridization (FISH) analysis has shown that the breakpoints are clustered within the ETS-variant gene 6 (ETV6) at 12p13, leading to its fusion with a variety of(More)
