background: the possible role of cochlear function in tinnitus generation is still a matter of debate. to assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (uhf) hearing sensitivity, transient evoked otoacoustic emissions (teoae) and uhf hearing thresholds were investigated in normal hearing individuals with and without tinnitus. ...

Using panel data we investigate the relationship between income inequality and economic development. We employ a threshold regression model that allows for endogenous income thresholds and find strong evidence of a two-regime split in our sample.  2000 Elsevier Science S.A. All rights reserved.

OBJECTIVES Through the National Health Service (NHS) Bowel Cancer Screening Programme (BCSP), men and women in England aged between 60 and 74 years are invited for colorectal cancer (CRC) screening every 2 years using the guaiac faecal occult blood test (gFOBT). The aim of this analysis was to estimate the cost-utility of the faecal immunochemical test for haemoglobin (FIT) compared with gFOBT ...

(See e.g. [2], [6] or [18]. Of course p0(n) is not quite unique, but following common practice we will often say “the” threshold when we should really say “a.”) It follows from [8] that every {Fn} has a threshold, and that in fact (see e.g. [18, Proposition 1.23 and Theorem 1.24]) p0(n) := pc(Fn) is a threshold for {Fn}. So the quantity pc conveniently captures threshold behavior, in particular...

Introduction: Neonatal hyperbilirubinemia is one of the most important factors affecting the auditory system and can cause sensorineural hearing loss. This study investigated the relationship between behavioral hearing thresholds in children with a history of jaundice and the maximum level of bilirubin concentration in the blood.   Materials and Methods: This study was performed on 18 children...

Increasing evidence from the empirical economic and psychological literature suggests that positive and negative well-being are more than opposite ends of the same phenomenon. Two separate measures of the dependent variable may therefore be needed when analyzing the determinants of subjective well-being. We investigate asymmetries in the effect of income on subjective well-being with a single-i...
