TY - RPRT U1 - Arbeitspapier A1 - Vormann, Claus T1 - Say what you pay? Pay Information Disclosure in German Job Postings N2 - Purpose – Pay transparency is a promising topic both for research and practice. In particular, the new European directive on compensation transparency will increase its importance. However, research is still relatively sparse compared to other areas of HRM. In particular, state-of-the-art and use of pay information disclosure in job postings is neglected. This paper aims to shed light on this HRM topic. Methodology – The paper summarizes the findings of a preliminary study conducted among German companies researching the proportion of firms offering compensation information in job postings and digging into the reasons behind it. Findings – Only 17 % of the participating companies disclose meaningful information about compensation in their job postings. Doing so mainly depends on the company’s attitude towards pay transparency. The age of the company has a minor negative influence, i.e.~older companies are less prone to disclose salary information. Industry, size, and existing overall pay transparency in the company do not determine if pay information is disclosed in job postings. Research limitations – The main limitation of this survey is its small size of 88 participants and the snowball sampling approach employed. This limits its representativeness and calls for follow-up studies involving more companies and a wider variation of positions included. Practical implications – While the EU directive will make it obligatory to communicate about pay before the first interview, some companies do it already. The study helps HR departments that think about changing their practice before it becomes compulsory to better judge the current standards.

Gestützt auf eine breite empirische Untersuchung zu den Erfahrungen von AbsolventInnen der Fachbereiche Sozialarbeit und Sozialpädagogik in Dortmund werden die überwiegend positiven Rückmeldungen der u.a. auf den Zusammenhang mit einschlägigen praktischen Vorerfahrungen, der Art des Trägers und dem Geschlecht überprüft. Insgesamt wird deutlich, dass der Beitrag der FH-gestützten Ausbildung für den Erfolg des Anerkennungsjahres und die Praxistauglichkeit kaum nachzuweisen ist. Der Verfasser sieht einen Grund für diese Feststellung in dem für das Sozialwesen typischen Merkmal des "weichen Studiengangs".

Based on the MIPS instruction set program data is generated and introduced in the simulation by means of initialization files. Before the simulation, technology specific SRAM modules are integrated into theMIPS core. Two different programs are used for power characterization. The first program performs frequent memory accesses by means of load/store word instructions, while the second program is a loop which operates on registers only and mainly increments addresses. The simulation is based on a virtual prototype which is generated by synthesis and place & route including post-layout parasitic extractions. The stimuli for the power extraction is generated via gate-level simulation and forwarded to the power calculation engine. The effect of X-propagation on gate-level simulations is avoided by modifying the address-related statements in the execution data path module, which use another form of 2 to 1 multiplexer, setting the output to zero for all input signals even with an initial value of ’x’ without changing the functionality. Finally, the consumed power is provided by reports generated by the power simulation engine. The memory-centric program consumes 35.39mW of internal power using instructions, which is 0.73mW less than the internal power of the register-centric program, and the overall average power is also lower by almost 0.7mW.

Based on the measurement of the time interval, distance can be calculated by applying the equation of motion. In application, achieving an exact distance measurement is quite strenuous because the operating conditions of the design are susceptible to change due to environmental factors. Therefore, to achieve accuracy in distance measurement, the time interval between the emission and reception of light must be measured precisely. For this purpose, a delay asymmetry compensation logic is developed. This thesis elaborates the addition of debugging features, redesign of some components, digital calibration approach and the entire testbench environment of the delay asymmetry compensation logic. It also sheds light on the implementation of the designed logic for its successful realisation in real hardware. Lastly, it concludes by narrating future prospects and further scopes of development.

A sophisticated CAE workflow is used to calculate the operational characteristics of 50 machine designs with 50 impeller geometry variations each. A Kriging-based surrogate model is trained to approximate the efficiency of any machine designs' best geometry design. The models are implemented into a machine design workflow. As a result, duty-specific Cordier lines are introduced. They are automatically generated for a set of machine design parameters. The efficiency of the designs along the duty-specific Cordier lines is approximated. Using optimization techniques, an optimal compressor design for the given duty on every specific Cordier line may be identified. This highly increases the amount of information available in the early design stages for radial turbocompressors.

The model enables the calculation of a compressor's chord Reynold's number during the machine design process. The chord Reynold's number is shown to be the most accurate representation of the fluid dynamic properties inside the radial turbocompressor's impeller. It — however — requires the computation of the chord length, which is only available after defining the final impeller geometry. The method presenting in this paper only employs the compressors principal dimensions to approximate the chord length. The chord is modelled using a Bézier spline and quarter ellipse. This enables the earlier use of the chord Reynold's number during the machine design process of radial turbocompressors.

The effects of radiation on electronic components are explained, followed by an introduction to the FPGAs used. The GateMate FPGAs leakage current is measured in its application area with respect to temperature and core voltages. A comparable testing environment is used from the tester to the tested device, as it will later be used at CERN. The GateMate is being prepared in this setup for the finalization of radiation qualification at CERN, to be transferred later. For this purpose, the basic tests are explained and the outstanding tests are then carried out. The Lattice iCE40 UltraLite FPGA is used in an initial application test to determine its suitability for further radiation qualification tests at CERN. The analysis and presentation of the test results are followed by a summary and outlook. N2 - Diese Arbeit behandelt die Entwicklung von Testumgebungen mit einem Xlinix Zynq SoC zur Messung von Leckströmen sowie der Strahlenqualifizierung von SRAM basierten FPGAs am CERN. Zunächst werden die Effekte von Strahlung sowie deren Wirkung auf elektronische Komponenten erläutert. Anschließend wird eine Einführung in die verwendeten FPGAs gegeben. In der Durchführung wird der Leckstrom des GateMate FPGAs in seinem Einsatzbereich hinsichtlich Temperatur und Core-Spannungen gemessen. Es wird eine Testumgebung mit ähnlichen Verbindungen zwischen Tester und Testgerät verwendet, wie sie später bei Bestrahlungsstudien am CERN Anwendung findet. Der GateMate wird in diesem Setup für die Finalisierung der Strahlenqualifikation vorbereitet, um die spätere Inbetriebnahme am CERN zu beschleunigen. Dazu werden die Tests grundlegend erläutert und die noch ausstehenden im Anschluss durchgeführt. Der Lattice iCE40 UltraLite FPGA wird in einem ersten Applikationstest eingesetzt, um seine Eignung für weitere Tests zur Strahlenqualifikation am CERN zu bestimmen. Die Ergebnisse aller durchgeführten Tests werden ausgewertet und dargestellt. Abschließend wird eine Zusammenfassung mit Ausblick präsentiert.
