Crowdsourcing enables the use of heterogeneous background knowledge from volunteers and distributes the annotation process to small portions of efforts from different contributions.
Detailed information on migration trends in Europe is not matched by systematic data on the health of these migrants, and their characteristics: they comprise a broad set of sub-groups with heterogeneous backgrounds (e.g. asylum seekers from war-torn areas, students moving within the EU and economic migrants) who have varying risk factors and health profiles.
In that setting, estimating multiple level sets for different geometries could prove useful, especially to estimate different regions of the heterogeneous background such as adipose and fibroglandular tissue.
Instead of achieving a representative sample like a random sampling survey would do, my purpose is to produce a set of systematic data from people with heterogeneous backgrounds with regard to age, gender, occupation, industry, hometown, education and income.
Despite this, the variation in responses was so striking that we expect that with the inclusion of more international experts with more heterogeneous backgrounds this variation would only become even more prominent.
The population is comprised of heterogeneous ethnic backgrounds from every region of the country.
Bond and Kamil (2006) [36] examined relationships between spatial heterogeneity and prey recognition by predators, and they concluded that colour morphs in less heterogeneous backgrounds were more readily detected than those in more heterogeneous backgrounds, even at the same level of background matching.
Recently, MIREAP (http://sourceforge.net/projects/mireap/files/mireap/) and miRDeep [ 25] were developed for the identification and prediction of mature miRNAs from the heterogeneous background of high-throughput sequencing data based on the compatibility of miRNA biogenesis model with the distribution characteristics of short reads on candidate precursors.
In large, groups of doctors with heterogeneous background (specialists in general practice, gastroenterology and gastrointestinal surgery) had concurrent evaluations, except for a minor difference concerning the patients' responsibility.
In order to derive more conclusive observations, it is recommended that this pilot study could be carried out over time, prior and after board exams and with more numbers of students from heterogeneous background such as different schools (public and self-financed schools), living area, and family conditions.
