The 18th Social Survey is part of the series of studies on the economic and social condition of student life in Germany, which exists since 1951. It is a cross-sectional survey that is usually conducted every three years. The core of the Social Survey includes questions on access to higher education, structural characteristics of studies and the course of studies, the social and economic situation (financing of studies, cost of living, gainful employment, housing situation), topics relating to the fields of activity of the Studentenwerke as well as socio-demographic characteristics. The data from the 18th Social Survey provide a snapshot [...] Full abstract: https://doi.org/10.21249/DZHW:ssy18:1.0.0

The 21st Social Survey is part of a survey series regarding the economic and social situation of students conducted since 1951 by the German National Association for Student Affairs (DSW) as part of their social survey. The Social Survey is a cross-sectional study which is usually carried out every three years. Key components of the study include access to higher education, structural aspects of the course and progress of studies, the economic and social situation (financing of studies, living expenses, employment, housing conditions) as well as topics in the field of activity of the German National Association for Student Affairs and socio-demographic characteristics.

Parallel data mining is utilized to improve the performance of analyzing large databases within a reasonable time frame. Exploring associative rules is an important task in data mining with various practical applications that can be used to explore knowledge in the form of a set of repetitive items or associative rules. Parallel algorithms divide the data superficially and then using different distribution approach, like data distribution, candidate and numerical candidate distribution, extract the set of repetitive items, and ultimately explore strong association laws. In this paper, a parallel algorithm is proposed to explore the collection of repetitive items from big and dense transaction databases.

The DZHW Panel Study: Careers of PhD Holders 2014 is a panel study of the DZHW concerning the careers of doctoral graduates. The study analyses how the formal context as well as the learning and development conditions that PhD graduates experienced during their doctorate studies influence the transition into employment and the further development of their professional career, both within as well as outside academia. The basic population comprises all persons who obtained a doctorate degree from a higher education institution with the right to award doctorates in Germany in the examination year of 2014.

Code clones can happen in any software project. One of the challenges is that, code clones come in various forms which makes them hard to detect using standard templates. Due to this variety in structure and form of semantically similar clones, machine learning techniques are required to detect them. Recently in many domains, e.g., natural language processing, deep neural networks drew a lot of attention due to their accuracy. In this paper, we exploit the results of some convolutional neural networks for code summarization to find the code clones. We use the generated descriptions for two code snippets as a metric to measure the similarities between them. We propose a vector similarity measure to calculate a similarity indicator between th

The DZHW Graduate Panel 2009 is part of the DZHW Graduate Survey Series, which compiles information on study, career entry, career development and further qualifications of higher education graduates using standardised surveys. The first Graduate Panel was created in 1989. Since then, every fourth graduate year (cohort) has been surveyed. For each graduate cohort, a series of survey waves are carried out, with each wave occurring at differing time intervals following the completion of degree. The DZHW Graduate Panel 2009 comprises the sixth graduate cohort of the survey series. Similar to the 2005 cohort, the study phase of the 2009 cohort is defined by the transformation [...] Full Abstract: https://doi.org/10.21249/DZHW:gra2009:1.0.1

The DZHW Panel Study of School Leavers 2008 is part of the School Leavers panel series of the DZHW, which records information on post-school educational and career paths of school leavers with a higher education entrance qualification. For every graduate year (cohort) a series of survey waves are carried out with each wave occurring at a different time before and after graduation, implemented as a combined cohort-panel-design. The Panel Study of School Leavers 2008 comprises the 17th cohort of the survey series with three survey waves. In contrast to preceding cohorts, the study phase of the 2008 cohort is defined by the implementation of the two-cycle degree programme [...] Full Abstract: https://doi.org/10.21249/DZHW:gsl2008:1.0.0
