The Collaboration of Human Resource Management and Line Management–An International Comparison

The extant research advocates for the strategic integration of human resource management (HRM) in managerial decision making to foster firm performance. However, the empirical evidence of a stronger strategic integration of HRM is still limited, especially in terms of strategic guidelines such as a human resource (HR) strategy and international comparative matters. Drawing on responses from 588 German and US-based organizations and related to the new institutionalism theory, this study examines whether a HRM partnership (i.e., sharing responsibilities between HRM and line management) that represents a particular form of strategic integration of HRM is beneficial for organizations. In particular, we find international differences as a more pronounced HRM partnership increases employee turnover in the USA, whereas no significant changes are encountered in Germany. We further demonstrate that organizations located in the USA are more likely to have a formal HR strategy compared to those in Germany. However, this study can neither provide support for the direct effect of a HRM partnership on employee turnover nor of a moderation of this relationship through the HR strategy

Recognizing opportunities across campus: the effects of cognitive training and entrepreneurial passion on the business opportunity prototype

We analyze the effects of the program Cognitive Entrepreneurial Training in Opportunity Recognition on the accurate assessment of prototypical viability of business opportunities. The training integrates the principles of experiential learning and is designed to reach students across campus. We also investigate the moderating role of entrepreneurial passion on opportunity recognition learning. We use a quasi-experimental design with pre-test, post-test in two European universities. The results demonstrate that the training has positive significant effects on the accurate identification of business opportunities' prototypical viability. Intense positive feelings about entrepreneurship moderate the learning process. We provide insights into entrepreneurship education practice across campus.info:eu-repo/semantics/publishedVersio

Joint H.E.S.S. and Fermi-LAT analysis of the region around PSR J1813-1749

HESS J1813-178 is one of the brightest sources detected during the first HESS Galactic Plane survey. The compact source, also detected by MAGIC, is believed to be a pulsar wind nebula powered by one of the most powerful pulsars known in the Galaxy, PSR J1813-1749 with a spin-down luminosity of $\dot{\mathrm{E}} = 5.6 \cdot 10^{37}\,\mathrm{erg}\,\mathrm{s}^{-1}$. With its extreme physical properties, as well as the pulsar's young age of 5.6 kyrs, the $\gamma$-rays detected in this region allow us to study the evolution of a highly atypical system. Previous studies of the region in the GeV energy range show emission extended beyond the size of the compact H.E.S.S. source. Using the archival H.E.S.S. data with improved background methods, we perform a detailed morphological and spectral analysis of the region. Additionally to the compact, bright emission component, we find significantly extended emission, whose position is coincident with HESS J1813-178. We reanalyse the region in GeV and derive a joint-model in order to find a continuous description of the emission in the region from GeV to TeV. Using the results derived in this analysis, as well as X-ray and radio data of the region, we perform multi-wavelength spectral modeling. Possible hadronic or leptonic origins of the $\gamma$-ray emission are investigated, and the diffusion parameters necessary to explain the extended emission are examined.Comment: 8 pages, 4 figures, 1 table, In proceedings of ICRC202

Dual Stimuli-Responsive Polysaccharide Hydrogels Manufactured by Radiation Technique

Featured Application Stimuli-responsive hydrogels encompassing biobased polymers are anticipated for utilization in various fields, starting from drug delivery systems through temporal actuators and water reservoirs to biodegradable microelements and nutrient delivery depots. This paper describes the results of the radiation-induced crosslinking of polysaccharides modified with hydroxypropyl and carboxymethyl functional groups, hydroxypropylcellulose (HPC) and carboxymethylcellulose (CMC), respectively, without and with poly(ethylene glycol) diacrylate (PEGDA) as a crosslinking agent, to obtain dual stimuli-responsive hydrogels. The gels were characterized in terms of water uptake and gel fraction, parameters that mainly depend on the HPC-CMC compositions, but also on the macromer crosslinker content and the absorbed dose. The swelling of hydrogels is controlled by both the temperature, due to the amphiphilic character of HPC and pH, due to the anionic functional groups of CMC. In spite of a similar degree of substitution in both cellulose derivatives, 1.4 for HPC and 1.2 for CMC, the pH response of hydrogels with an equal content of both polysaccharides is considerably higher-a reduction in swelling of up to 95% with a decrease in the pH to 2 was recorded-than the response to thermal-stimulus-wherein a reduction in swelling of less than 70% with an increasing in temperature to 55 degrees C was found. These biopolymers-based hydrogels of specific, stimuli-responsive swelling properties are anticipated in applications where a combination of two stimuli is essential and biodegradation may be required

Acetylcholinesterase, Tyrosinase, α-Glucosidase inhibition by Ammodaucus leucotrichus Coss. & Dur. Fruits Essential oil and Ethanolic Extract and Molecular Docking Analysis

Medicinal and aromatic plants serve as valuable reservoirs of bioactive molecules and mineral compounds that are harnessed for therapeutic and agro-food applications. The objective of this study was to assess the inhibitory enzyme properties of Ammodaucus leucotrichus Coss & Dur fruit essential oil, as well as its aqueous and ethanol extracts, against acetylcholinesterase, tyrosinase, and α-glucosidase. Additionally, the antioxidant activity of these natural mixtures was evaluated using three different methods: DPPH, FRAP, and β-carotene bleaching tests. Furthermore, this research endeavors to examine the mineral constituents of various components of the plant under investigation. The various natural combinations that were examined exhibited a notable inhibitory impact on the enzymes acetylcholinesterase (67.56-92.30%), tyrosinase (57.52-63.44%), and α-glucosidase (61.22-72.49%). The analyzed extracts also demonstrate a significant antioxidant activity. Furthermore, the results obtained from the analysis indicate a notable presence of both macro and microelements, such as calcium (2.028 mg/g for leaves and 1.787 mg/g for fruits), within the Ammodaucus leucotrichus Coss & Dur plant. The current study supports the significance of utilizing Ammodaucus leucotrichus Coss & Dur fruits in the medicinal and agro-alimentary sectors. The utilization of molecular docking techniques was employed in order to make predictions regarding the therapeutic effects of Ammodaucus leucotrichus Coss & Dur fruits
