This paper deals with the relative economic performance of immigrants compared to the native born population in Germany. We compare pre-and post-government income, using data from the German SocioEconomic Panel from 1995 to 1997. We categorize six population subgroups by the ethnicity of the adult household members: native-born West Germans, East Germans, " pure " Aussiedler (ethnic German immi...

The Native American population in South Dakota accounts for more than 8 percent of the state-wide population as per the 2000 U. S. Census. The primary purpose of this study was to survey a segment of this population base, and identify the percentage of South Dakota’s Native Americans that do not own computers, or have access to the Internet and subsequently are classified as being affected by t...

Genetic diversity of present American populations results from very complex demographic events involving different types and degrees of admixture. Through the analysis of lineage markers such as mtDNA and Y chromosome it is possible to recover the original Native American haplotypes, which remained identical since the admixture events due to the absence of recombination. However, the decrease i...

This study investigated the extent and nature of university students’ use of digital technologies for learning and socialising. The findings show that students use a limited range of mainly established technologies. Use of collaborative knowledge creation tools, virtual worlds, and social networking sites was low. ‘Digital natives’ and students of a technical discipline (Engineering) used more ...

This paper interrogates the currently pervasive discourse of the 'net generation' finding the concept of the 'digital native' especially problematic, both empirically and conceptually. We draw on a research project of South African higher education students' access to and use of Information and Communication Technologies (ICTs) to show that age is not a determining factor in students' digital l...

This article takes a critical look at three pervasive urban legends in education about the nature of learners, learning, and teaching and looks at what educational and psychological research has to say about them. The three legends can be seen as variations on one central theme, namely, that it is the learner who knows best and that she or he should be the controlling force in her or his learni...

Endocarditis due to Legionella spp. is uncommon but presumably underestimated given the prevalence of Legionellae in the environment. We report a first and unusual case of chronic native valve endocarditis due to L. anisa and advocate that the diagnosis of endocarditis be made collaboratively between the cardiologist, surgeon, microbiologist and pathologist.

This paper illustrates the use of WELSA adaptive educational system for the implementation of an Artificial Intelligence (AI) course which is individualized to the learning style of each student. Several issues are addressed throughout this paper: i) What similar approaches exist in the literature?; ii) How is the AI course created?; iii) What kind of personalization is provided in the course a...

Educational computer games are sometimes considered to be motivating per se – because of the playing activity and do not require further motivational strategies. Therefore the concept of ‘flow experience’ is commonly used to describe how smooth gaming naturally results in deep engagement and, consequently, enhanced learning. Learning with an instructional game without discovering the instructio...

Nucleotide sequence analysis of the major noncoding region of human mitochondrial DNA from various races was extended with 72 Native Americans from 16 different local populations (nine populations from Chile, four from Colombia, and one each from Brazil and from Maya and Apache Indians). The sequences were determined directly from the polymerase chain reaction products. On the basis of a compar...
