Queueing Systems on a Circle [PDF]

open access: yesZOR Zeitschrift f�r Operations Research Methods and Models of Operations Research, 1993
Summary: Consider a ring on which customers arrive according to a Poisson process. Arriving customers drop somewhere on the circle and wait there for a server who travels on the ring. Whenever this server encounters a customer, he stops and serves the customer according to an arbitrary service time distribution.

Commissioning an Inexpensive Off‐The‐Shelf Spectrograph for Radial‐Velocity Studies

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We present a way to set up an inexpensive out of the shelf spectrograph at a local observatory. Stability and resolution of the spectrograph are high enough for radial velocity determination of binary stars or determination of stellar characteristics. Even some exoplanets might be detectable via the radial velocity method.

Flexible Queueing Architectures

open access: yes, 2017
We study a multi-server model with $n$ flexible servers and $n$ queues, connected through a bipartite graph, where the level of flexibility is captured by the graph's average degree, $d_n$. Applications in content replication in data centers, skill-based

The Impact of Self‐Checkout Technology on Shopping Behavior in B2B Retail: Evidence From Point‐Of‐Sale Transaction Data

open access: yesJournal of Consumer Behaviour, EarlyView.
ABSTRACT This study examines the impact of self‐checkout technology implementation on B2B customer shopping behavior using a novel methodological approach that combines propensity score matching with difference‐in‐differences analysis on actual point‐of‐sale transaction data.

Service Work as Lived Experience: A Problematizing Review

open access: yesHuman 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

Beyond Truth‐Telling: A Replication Study on School Choice

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT In a recent paper, Fack et al. (2019, American Economic Review) convincingly argue and theoretically demonstrate that there may be strong incentives for students to play non‐truth‐telling strategies when reporting preferences over schools, even when the celebrated deferred acceptance algorithm is employed.
