The Identification and Economic Content of Ordered Choice Models with Stochastic Thresholds This paper extends the widely used ordered choice model by introducing stochastic thresholds and interval-specific outcomes. The model can be interpreted as a generalization of the GAFT (MPH) framework for discrete duration data that jointly models durations and outcomes associated with different stoppin...

Using the so-called mean-reverting square-root process of Cox et al. (1985b) we generalize the work of Dias and Shackleton (2005) by introducing the mean reversion feature into the economic hysteresis analysis under stochastic interest rates and show that such issue highlights a tendency for a widening effect on the range of inaction, though both thresholds have risen when compared with the no ...

Background: Cortical Evoked Response Audiometry (CERA) refers to prediction of behavioral pure-tone thresholds (500-4000 Hz) obtained by recording the N1-P2 complex of auditory long latency responses. CERA is the preferred method for frequency–specific estimation of audiogram in conscious adults and older children. CERA has an increased accuracy of determination of the hearing thresholds of ale...

    Background & Aim: The most common surgically treatable causes of hearing loss are middle ear diseases among which the greatest effect is related to ossicular chain dysfunction. Successful ossicular chain reconstruction certainly improves air conduction thresholds and closes air-bone gap in audiograms, but the effect of this procedure on bone conduction thresholds has remained to be elucidat...

Grapevines are crops of global economic importance that will face increasing drought stress because many varieties are described as highly sensitive to hydraulic failure as frequency and intensity of summer drought increase. We developed and used novel approaches to define water stress thresholds for preventing hydraulic failure, which were compared to the drought stress experienced over a deca...

this study was based on the hypothesis that “ecotourism is an important instrument in sustainable rural development and ecologically-based landscape planning approaches which take the objectives of socio-economic development and nature conservation have an effective role in this issue”. for this purpose, the necessity of ecologically-based landscape planning approaches in the planning and imple...
