Reciprocity in Gift-Exchange-Games

This paper presents an analysis of data from a gift-exchange-game experiment. The experiment was described in `The Impact of Social Comparisons on Reciprocity' by G\"achter et al. 2012. Since this paper uses state-of-art data science techniques, the results provide a different point of view on the problem. As already shown in relevant literature from experimental economics, human decisions deviate from rational payoff maximization. The average gift rate was $31$%. Gift rate was under no conditions zero. Further, we derive some special findings and calculate their significance.Comment: 6 pages, 2 figures, 5 table

A Challenge of Vocational Education for Preparing Green Employment

Currently the vocational education has been oriented to the educational processes in which focusing on the development of the student in order to ready to work professionally and ready to improve their self-potential in particular field work. Meanwhile, today and future jobs in various business sectors and industry are still growing and developing towards green jobs. If there is no counter and solution for this growth of green jobs, then it would create a new gap between the output\u27s competencies of vocational education and the qualification that needed by various business sector and industry. After studying some latest literatures, it was found that there is no any explicitly and concretely both concept and definition of green jobs in the vocational education curriculum (Curriculum 2013). Thus, this paper presents the urgent and such a challenge to change the philosophy of vocational education towards green jobs and ecology oriented

Molecular Diagnostics in Colorectal Cancer

Colorectal cancer (CRC) presents in one of three patterns: sporadic colorectal cancer in those without a family history (65-85%); those with a family history (familial CRC) 10-25% of cases; inherited CRC accounting for less of 10% cases and presents as well-characterized cancer predisposition syndromes including Lynch syndrome (hereditary non-polyposis colorectal cancer/HNPCC) which comprises about 1-5% of all colorectal cancer, and multiple polyps CRC, which includes familial adenomatous polyposis (FAP,1%), rare CRC syndrome < 0.1 %). Many efforts have been made to discover the genetic and molecular features of CRC, and there is more evidence that these features determine the prognosis and response to treatment. Colorectal cancer (CRC) is a heterogeneous disease, with three known major molecular groups. The most common is the chromosomal instability group, characterized by an accumulation of mutations in specific oncogens and tumor suppressor genes. The second is the microsatellite instability group, caused by the dysfunction of deoxyribonucleic acid (DNA) mismatch repair genes leading to genetic hypermutability. The CpG island methylation phenotype (CIMP) is the third group, distinguished by hypermethylation. In this review we would like to provide an up-to-date overview of molecular genetic aspects of CRC that are currently important and should guide clinical practice in colorectal cancer in the diagnosis and selection of therapy
