Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT A common assumption is that firms become more socially responsible over time. Indeed, numerous conceptual papers focus on the issue of describing the CSR states that firms advance through. Yet, related empirical research remains limited and the assumption of steady progression across CSR states remains untested.

Stationary characteristics of unreliable queueing system with a batch Markovian arrival process
Informatika, 2019 Unreliable queuing systems are of considerable interest both in mathematical terms and for applications. Systems with stationary Poisson flows of customers and breakdowns and exponentially distributed service and repair times are mainly considered.

Operations Research PerspectivesThe superposition of arrival processes is a fundamental yet analytically intractable operation in queueing networks when inputs are general non-renewal streams.

An s, S Production Inventory Controlled Self-Service Queuing System
Journal of Probability and Statistics, 2015 We consider a multiserver Markovian queuing system where each server provides service only to one customer. Arrival of customers is according to a Poisson process and whenever a customer leaves the system after getting service, that server is also ...

British Journal of Educational Technology, EarlyView.Abstract As students learn and practice new skills in university courses, their behaviour can change in response to competing demands and increasing content complexity. However, most metrics used to evaluate study behaviour focus on the number or sequence of activities rather than on the change of behaviour.

Performance approximations of Markov Modulated Poisson Process arrival queue with Markovian Service using matrix geometric approach [PDF]
Yugoslav Journal of Operations ResearchQueue analysis of correlated work of the arrival and the service process are not available much in literature. This research paper applies matrix geometric approach to study the MMPP/MSP/1 queuing model under the quasi-birth death(QBD) process. Customers

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Commercial laying hen breeding programs aim to maximize the performance of crossbred animals. However, selection is usually based on data from pure lines raised in controlled nucleus environments, which may not fully predict the yields under commercial conditions.

Non-identifiability of the two state Markovian Arrival process [PDF]
, 2009 In this paper we consider the problem of identifiability of the two-state Markovian Arrival process (MAP2). In particular, we show that the MAP2 is not identifiable and conditions are given under which two different sets of parameters, induce identical ...

Two‐layer modelling of IEEE 802.11x channel occupancy
Electronics Letters, 2023 Low power IoT communication signals (e.g., Bluetooth and ZigBee) may seriously suffer from the presence of high‐power co‐channel interference like wireless local area network (WLAN) signal.

Longevity, Health, and Housing Risk Management in Retirement
The Journal of Finance, EarlyView.ABSTRACT Annuities, long‐term care insurance, and reverse mortgages remain puzzlingly unpopular to manage post‐retirement longevity, health, and housing price risks. We use a flexible life‐cycle model structurally estimated with a unique stated‐preference survey experiment of Canadian households to understand why. Key factors include high risk aversion,
