The project addresses the transition from school to initial vocational training. The aim is the longitudinal examination of the development of trainees' career-related mathematical-scientific competencies in connection with the corresponding competencies which they have acquired in school. The sample comprises 3,000 trainees from dual training programmes in which career-related mathematical-scientific learning processes will be systematically examined in work and school contexts. The planned surveys will be carried out at the start of the training programme, in the middle and at the end of the programme. The main challenge will be to provide reliable and valid instruments for surveying career-related mathematical-scientific competencies.
There is increasing consensus in the economic and social sciences that the workplace plays a crucial role in individual life outcomes. For this reason, there has been a growing interest in "linked employer-employee" (LEE) datasets, in which employees' individual data are linked with information on their employers. The workplace data collected during the SOEP-LEE project will substantially expand the information on the work contexts and working conditions of respondents to the Socio-Economic Panel (SOEP) survey. The project is conducted in cooperation with Bielefeld University and has been implemented by asking all dependent employees in all of the SOEP samples to provide local contact information to their employer in 2011. The employer contact data formed the basis for a separate standardized employer survey conducted in winter 2012/2013. This employer information can then be linked with the individual and household data from the SOEP study. The resulting linked employer-employee dataset opens up new opportunities for the analysis of a wide range of innovative questions. The thematic focus of the employer survey is the production of social inequalities to answer the question how inequalities, e.g. in access to key resources and life opportunities, come into being at the workplace level. An additional unique feature of SOEP-LEE is the analysis of employer survey data quality, carried out through the measurement of meta- and paradata over the course of data collection. As a result, this project also contributes to the ongoing development and refinement of survey methodology in the field of organizational studies.
The continuous increase in life expectancy and age-related diseases represents an ethical and economic challenge to human society. The project aims to identify molecular networks underlying the exceptional healthy longevity (healthspan) of naked mole-rats. Defying the common trade-off between fecundity and lifespan, reproductive individuals of eusocial species have developed mechanisms resisting ageing. Mole-rats provide a unique opportunity to study the transition of shorter-lived non-breeders into longer-lived breeders. Comparative transcriptomics with free-ranging mole-rats, guinea pigs and mice shall identify underlying genes, subsequently validated in cell culture. Obtained results are aimed at translation into sustained health in an ageing human society.
Glutamate receptors (iGluRs) are cornerstones of excitatory neurotransmission. Faulty signaling at excitatory synapses is implicated in cognitive defects and diseases of the nervous system. The goal of this proposal is to modify iGluRs, allowing us to measure them in a new way, in order to better understand glutamate receptors in the brain. With FMP chemical biologists, we will develop high‐throughput screens exploiting these modified iGluRs.
A new generation of ultra-high power laser-induced fusion (LIF) systems is under construction world wide, for power generation and basic research. A new kind of diode laser with drastically improved performance is required, and will be developed here. A tenfold increase in optical output power density and > 80% power conversion efficiency will be enabled by using innovative device designs optimized for sub-zero (200K) operation. Diode lasers with internal gratings will ensure narrow spectral widths. The FBH will perform diode laser research, technology development and prototype construction. The two world-leading LIF groups are project partners and will assess the prototypes.
Formulas are an important characteristic of mathematical publications. Mathematical formulas have a rash of special features, e.g., mathematical symbols or complexity. Special languages were developed to create and handle mathematical formulas. The presentation and analysis of mathematical formulas is more complicated than normal text.
In this pilot project, new concepts and tools for the analysis and retrieval of mathematical formulas will be developed. The methods and tools will be used in the database zbMATH (Zentralblatt for mathematics). The database zbMATH contains the bibliographic data including reviews and abstracts of more than 3,200,000 mathematical publications and is the most comprehensive bibliographic database in mathematics.
For the project, a glossary of mathematical formulas will be build up. Concepts for the formula analysis and retrieval will be developed basing on an adequate encoding of formulas and a syntactic analysis. In the result of the project, the user can search for mathematical objects and statements in a more precise way than today.
The methods developed in the project can be used also for digital mathematics libraries and repositories.
Target of the project is the deposition of monocrystalline semiconducting layers from beta-Ga2O3-In2O3-Al2O3 systems of high quality on beta-Ga2O3 and In2O3 homemade substrates by MOCVD. At first high-quality layers of binary oxide will be deposited. By doing this, we open the way to an extensive physical characterisation of these novel semiconducting oxides. Subsequently, ternary layers (In,Ga)2O3 and (Al,Ga)2O3 and relevant single/double heterostructures will be prepared with the aim of tailoring electrical and optical properties by appropriate design of strain and composition. Final target is the reproducible growth of heterostructures applicable in a new generation of opto- and microelectronic devices.
The main objective of our project is to combine novel laser technologies and materials to push the average power of few-optical-cycle near- and mid-infrared coherent laser sources. We will set up a high repetition rate broadband optical parametric amplifier for chirped pulses delivering pulses with several Watts of average power at 1.5µm and 3µm. The near infrared signal pulse will be carrier phase stabilized. Within the project we will also demonstrate the capabilities of this unique femtosecond laser for investigation of electron charge dynamics in Van-der-Waals molecules and the development of a novel way to monitor time-resolved structural dynamics in molecules.
