Age effects on consumer demand: An additive partially linear regression model
(2002)An additive partially linear regression model is used to estimate non-parametrically the effects of total expenditure and age in the context of Engel curves and to investigate the specification and welfare interpretation ...

Biodiversity patterns of terrestrial isopods from two island groups in the Aegean Sea (Greece): Species-area relationship, small island effect, and nestedness
(2008)Although almost one third of Aegean islands have an area smaller than 1 km2, very few studies have concentrated on this spatial Scale. We investigate biodiversity patterns of terrestrial isopods in 2 island groups (Kalymnos ...

Boron in groundwaters of Nicosia (Cyprus) and its treatment by reverse osmosis
(2007)Boron levels in groundwaters of Nicosia have been determined, compared to previous concentration data and correlated to the concentration of other chemical species contained in the groundwaters under investigation. According ...

Article
Comparing the true cost of living indices of demographically different households
(2004)The comparison of true cost of living indices between demographically different households (relative equivalence scale) is argued to be sensitive to the way demographic characteristics enter demand analysis. In particular, ...

A computer simulation scenario analysis approach as a decision support tool for transportation systems planning
(2007)As the level of traffic congestion rises and the complexity of traffic networks increases, the development of effective transportation strategies becomes the most challenging task for every transport authority. Meanwhile, ...

Article
Demographic versus expenditure flexibility in Engel curves
(2008)We consider the effects of demographic and expenditure variables on consumer demand in a system of Engel curves using a smooth coefficient semiparametric model where the expenditure effects on the budget shares vary ...

Determination of thorium, uranium and potassium elemental concentrations in surface soils in Cyprus
(2004)A comprehensive study was conducted to determine thorium, uranium and potassium elemental concentrations in surface soils throughout the accessible area of Cyprus using high-resolution γ-ray spectrometry. A total of 115 ...

Article
Estimates of the black economy based on consumer demand approaches
(2004)We propose a consumer demand system approach to estimating the size of the black economy where alternative hypotheses affecting the empirical results can be tested in a nested framework. This approach allows for the ...

Article
From sampling stations to archipelagos: Investigating aspects of the assemblage of insular biota
(2004)Aim To investigate the formation of nestedness and species co-occurrence patterns at the local (sampling station), the intermediate (island group), and the archipelago scale. Location The study used data on the distribution ...

Article
Gains from trade in used goods: Evidence from automobiles
(2008)I investigate the welfare effects of trade liberalization by exploiting a natural policy experiment in the economy of Cyprus. A 1993 law relaxed import restrictions on used vehicles and enabled the importation of second-hand ...

Article
An improved method for the identification of areas of endemism using species co-occurrences
(2008)Aim: To develop a simple method that (1) combines the notions of biotic elements (groups of taxa with ranges significantly more similar to each other than to the ranges of other taxa) and of areas of endemism (AoE, areas ...

Increased molecular divergence of two endemic Trachelipus (Isopoda, Oniscidea) species from Greece reveals patterns not congruent with current taxonomy
(2008)In the present study, we employed three mitochondrial DNA genetic markers in a phylogenetic analysis aiming at the delineation of the relationships amongst nominal Trachelipus kytherensis populations, as well as between ...

Long-run PPP under the presence of near-to-unit roots: The case of the British Pound-US dollar rate
(2009)Empirical tests typically provide evidence that the British pound-US dollar exchange rate and the relative wholesale price index contain exact unit roots and exhibit cointegration. However, the cointegrating vector is ...

Modelling precipitation in Sweden using multiple step markov chains and a composite model
(2008)In this paper, we propose a new method for modelling precipitation in Sweden. We consider a chain dependent stochastic model that consists of a component that models the probability of occurrence of precipitation at a ...

Natural radioelement concentration in the Troodos Ophiolite Complex of Cyprus
(2005)High-resolution γ-ray spectrometry was exploited to determine naturally occurring thorium (Th), uranium (U) and potassium (K) elemental concentrations in the whole area covered by the Troodos Ophiolite Complex of Cyprus. ...

Article
On estimating the cost of characteristics indices from consumer demand analysis
(2003)We examine the information content of relative equivalence scales using a multiperiod framework and argue that in the absence of Independence of Base (IB) these scales can be uniquely identified from demand analysis only ...

On the surrogate value of red-listed butterflies for butterflies and grasshoppers: A case study in Grammos site of Natura 2000, Greece
(2009)We tested the surrogate value of butterflies, red-listed butterflies and grasshoppers for each other in terms of diversity patterns congruence and complementarity at a site in the NATURA 2000 network. Grammos Mountain is ...

Operational ocean forecasting in the Eastern Mediterranean: Implementation and evaluation
(2008)The Cyprus Coastal Ocean Forecasting and Observing System (CYCOFOS) has been producing operational flow forecasts of the northeastern Levantine Basin since 2002 and has been substantially improved in 2005. CYCOFOS uses the ...

Patterns of species richness on very small islands: The plants of the Aegean archipelago
(2006)Aim: To investigate the species-area relationship (SAR) of plants on very small islands, to examine the effect of other factors on species richness, and to check for a possible Small Island Effect (SIE). Location: The study ...

Research spillovers among European and North-American economics departments
(2004)In this paper, we investigate the determinants of research output by European economics departments. We use data from a survey we conducted on the various characteristics of these departments. We pay particular attention ...
