Modelling the probability of land abandonment at parcel level
"... Introduction and aims In Austria the abandonment of agricultural land use has increased during the last four decades (e.g. about + 1.000 km² of fallow and set aside areas since 1970 [BMLFUW, 2004] and + 2.700 km² forest area since 1960 ..."

Stabilizing Customer Abandonment in ManyServer Queues with TimeVarying Arrivals
"... We develop analytical approximations to determine timedependent staffing levels to stabilize abandonment probabilities and expected delays in the Mt/GI/st + GI manyserver queueing model, which has a nonhomogeneous Poisson arrival process (the Mt), general service times (the first GI) and allows cu ..."

Efficiencydriven heavytraffic approximations for manyserver queues with abandonments
 Management Science
, 2004
"... Motivated by the desire to understand the performance of serviceoriented call centers, which often provide lowtomoderate quality of service, this paper investigates the efficiencydriven (ED) limiting regime for manyserver queues with abandonments. The starting point is the realization that, in ..."

that the probability of abandonment approaches a positive limit. To obtain the ED regime, it suffices to let the arrival rate and the number of servers increase with the traffic intensity ρ held fixed with ρ> 1 (so that the arrival rate exceeds the maximum possible service rate). Even though the probability
Waiting Patiently: An Empirical Study of Queue Abandonment in an Emergency Department
"... We study queue abandonment from a hospital emergency department. We show that abandonment is not only in uenced by wait time, but also by the queue length and the observable queue ows during the waiting exposure. For example, observing an additional person in the queue or an additional arrival to th ..."

to the queue leads to an increase in abandonment probability equivalent to a fteen minute or nine minute increase in wait time respectively. We also show that patients are sensitive to being "jumped " in the line and that patients respond di erently to people more sick and less sick moving through
A NearlyOptimal Index Rule for Scheduling of Users with Abandonment
"... Abstract—We analyze a comprehensive model for multiclass job scheduling accounting for user abandonment, with the objective of minimizing the total discounted or timeaverage sum of linear holding costs and abandonment penalties. We assume geometric service times and Bernoulli abandonment probabili ..."

Consequences of prejudice against the null hypothesis
 Psychological Bulletin
, 1975
"... The consequences of prejudice against accepting the null hypothesis were examined through (a) a mathematical model intended to stimulate the researchpublication process and (b) case studies of apparent erroneous rejections of the null hypothesis in published psychological research. The input param ..."

parameters for the model characterize investigators ' probabilities of selecting a problem for which the null hypothesis is true, of reporting, following up on, or abandoning research when data do or do not reject the null hypothesis, and they characterize editors ' probabilities of publishing
Modelling forest transition: Bistability of forested and abandoned landscapes
"... A historical generalization about forest cover change in which rapid deforestation gives way over time to forest restoration is called “the forest transition”. Prior research on the forest transition leaves three important questions unanswered. (1) How does forest loss influence an individual landow ..."
Abstract
 Add to MetaCart
assume that a forest is composed of many land parcels, each of which is in one of a finite list of landuse states. The landuse state of each land parcel changes stochastically. The transition probability is determined by two processes: the forest succession and the decision of landowners. The landowner
extraction
, 2011
"... We calculate the probability that an extraction project will be abandoned, directly from a real options model closely related the seminal work of Brennan and Schwartz (1985). We assume that the resource is extracted at two alternative rates, with a capital cost for switching, and with an option to a ..."
