Human Resources Data Analytics – Evidence from an Irish Manufacturing Perspective

Industry is propelled by measurement and the transformative potential of data analysis as a driver of business success. Human Resource (HR) departments have not escaped this impetus, indeed it has gained momentum over the last decade. The promise of analytics is significant: to replace gut and intuition with data-based decision making and evidence-based strategies. HR analytics hails itself as a framework to temper HR intuition with objectivity. It promises rigour and validity to guide and prioritise human capital expenditure. Despite enormous interest, evidence of practical application has been scarce. This research adopts an inductive, interpretivist approach, using multiple case studies of Irish manufacturing firms, underpinned by interviews with HR Managers and industry experts. It contributes to research and practitioner knowledge with insights of industry led practical applications of HR analytics and the levels and application of HR analytics within companies. Furthermore, it reveals the factors impacting application outcomes in firms

Modification of water retention and rheological properties of fresh state cement-based mortars by guar gum derivatives

International audienceThe present study examines the influence of chemical composition and structure of guar gum derivatives on water retention capacity (WR) and rheological behavior of fresh state cement-based mortars. The investigation was also completed by adsorption isotherms. For this, original guar gum, three HydroxyPropyl Guars (HPG) and two hydrophobically modified HPGs were selected. The effect of the molar substitution (MSHP) and of hydrophobic substitution (DSAC) was investigated. The results highlight that chemical composition of HPGs has a remarkable effect on fresh state properties of mortars. The original guar gum does not impact on neither WR nor rheological behavior. Increasing MSHP leads to an improvement of the WR and the stability of mortars while the hydrophobic units further enhance WR and lead to a decrease in the yield stress and an increase in the resistance to the flow of admixed mortars

Bandstructure and Fermi Surfaces of CeRh3B2

The electronic bandstructure and the Fermi surfaces of ferromagnetic CeRh3B2 are calculated by using FLAPW and LSDA+U method. As assuming several kinds of the ground state to describe the 4f electronic state, we propose a fully orbital- and spin-polarized state |lz=0, sx=1/2> as the ground state, instead of the conventional LS-coupled CEF ground state, generally expected in typical 4f compounds. This is supported by the fact that both the observed magnetic moment and the observed dHvA frequencies are well explained by the calculated electronic structure and the Fermi surfaces. The unconventional ground state is stabilized by the strong 4f-4f direct mixing between the neighbored Ce atoms along the extremely small distance along the c-axis in the hexagonal crystal cell.Comment: 8 pages, 9 figures, submitted to JPSJ (accepted and will appear in the issue of Vol.79, No.4
