A hierarchical consistency problem for the hierarchical supervisory control of discrete event systems under partial observation is considered, since observability is a practical and general property in real systems. The notion of H-observability is introduced to ensure hierarchical consistency between lowand high-level systems, and an analytical framework for the hierarchical supervisory contro...

Employee engagement is a relatively new construct in academia and has received considerable press attention. Employee engagement is linked to positive business unit outcomes such as profitability, productivity, employee turnover rate, satisfaction, customer loyalty, and safety. The objectives of this study are to propose and validate the reliability of a behavioral employee engagement scale. Th...

This article argues that the relatively new field of personnel economics (PE) holds strong potential as a tool for studying public sector workforces. This subfield of labor economics is based on a strong foundation of microeconomics, which provides a robust theoretical foundation for studying workforce and organizational design issues. PE has evolved on this foundation to a strong practical emp...

Hom, Mitchell, Lee, and Griffeth (2012) presented an extensive review of employee turnover research, reconceptualized the turnover criterion to include multiple destinations, and proposed to expand the predictor domain. They illuminated the multiple destinations employees pursue following turnover. By crossing desire to remain and volitional control dimensions, Hom et al. defined and described ...

Coalgebraic techniques are applied to the supervisory control of discrete-event systems with partial observations. Classical notions from concurrency theory are specialized to control theory. The concept of weak transitions enables the relational characterization of observability and gives rise to a coalgebraic formulation of the necessary and sufficient conditions for the existence of a superv...

Adaptive Controllers are susceptible to many commonly occurring implementation problems, and require some form of supervision to maintain good performance. In this thesis a two level adaptive control strategy is presented that uses an expert system to diagnose and correct problems with an adaptive controller. In contrast with other expert supervised adaptive control schemes, where problem treat...

This paper examines empirically the three concepts of loyalty that have been recently proposed in the literature: attitudinal loyalty, share loyalty, and differentiation loyalty. Measures of these concepts are compared at both aggregate (brand loyalty) and individual (customer loyalty) level. The findings support the view that each is indeed a separate concept, though each are, as hypothesised,...

Understanding the relative importance of dispersal limitation and environmental filtering processes in structuring the beta diversities of subtropical forests in human disturbed landscapes is still limited. Here we used taxonomic (TBD) and phylogenetic (PBD), including terminal PBD (PBDt) and basal PBD (PBDb), beta diversity indices to quantify the taxonomic and phylogenetic turnovers at differ...

This paper empirically investigates three hypotheses regarding biases of National Basketball Association (NBA) referees. Using a sample of 28,388 quarter-level observations from six seasons, we find that referees make calls that favor home teams, teams losing during games, and teams losing in playoff series. All three biases are likely to increase league revenues. In order to distinguish betwee...
