Service Work as Lived Experience: A Problematizing Review
Human Resource Management, EarlyView.ABSTRACT Between employee burnout and growing recruitment challenges, a systemic crisis confronts the service industry. One reason lies in the scope of received human resource management (HRM) approaches, which often emphasize organizational performance metrics at the expense of the emotional, social, and material experiences of doing frontline service

Precise estimation of tropospheric path delays with GPS techniques [PDF]
Tropospheric path delays are a major source of error in deep space tracking. However, the tropospheric-induced delay at tracking sites can be calibrated using measurements of Global Positioning System (GPS) satellites.

VEHICLE TRACKING SYSTEM USING GPS
, 2013 Global Positioning System is used for tracking vehicle. This paper describes vehicle tracking system with the help of GPS and Wi-Fi. Tracking unit is kept inside the vehicle. User can monitor moving vehicle using this system. Wi-Fi and GPS technology is powerful technology. GPS satellite transmits signals in the form of latitude and longitude.

Networks, EarlyView.ABSTRACT The analysis of certain properties of the underlying graph of a public transport network generates insights about the network's structure. Hereby, the choice of the graph representation depends on a trade‐off between complexity reduction and information preservation to adequately model a public transport network.
