Two Half-Truths Make a Whole? On Bias in Self-Reports and Tracking Data
2019
The pervasive use of mobile information technologies brings new patterns of media usage, but also challenges to the measurement of media exposure. Researchers wishing to, for example, understand the nature of selective exposure on algorithmically driven platforms need to precisely attribute individuals’ exposure to specific content. Prior research has used tracking data to show that survey-based self-reports of media exposure are critically unreliable. So far, however, little effort has been invested into assessing the specific biases of tracking methods themselves. Using data from a multimethod study, we show that tracking data from mobile devices is linked to systematic distortions in sel…

Measurement Invariance and Construct Validity of the Satisfaction With Life Scale (SWLS) in Community Volunteers in Vietnam.
2022
Worldwide, the Satisfaction With Life Scale (SWLS) has become the most widely used measure of life satisfaction. Recently, an authorized Vietnamese-language version has been introduced. Using a convenience sample comprising community volunteers from Ho Chi Minh City (N = 1073), confirmatory support was found for the cross-national constancy of the one-dimensional structure underlying the SWLS. Corrected item–total polyserial correlations and Omega coefficient were satisfactory. Using multi-group confirmatory factor analysis, configural, metric, and scalar invariance of the SWLS factorial structure were tested by gender, age, marital status, income, and educational level. Strong evidence of …
The atractiveness and competitiveness of tourist destinations: A study on Southern Italian regions
2009
The present paper aims to assess the relative attractiveness of competing tourist destinations on the basis of individual visitors' perceptions regarding a holiday destination. Using the feeling of tourist well-being achieved by individual tourists we evaluate indirectly the competitive ability of the tourist area to offer a compound tourist site attractiveness. The methodology employed here uses individual survey questionnaires on the tourists' evaluation of the quality of tourist facilities and attributes in a given area (the 'regional tourist profile') as the basis for constructing an aggregate expression for the relative attractiveness of that area. Using various multidimensional statis…
Scad-elastic net and the estimation of individual tourism expenditure determinants
2014
This paper introduces the use of scad-elastic net in the assessment of the determinants of individual tourist spending. This technique approaches two main estimation-related issues of primary importance. So far studies of tourism literature have made a wide use of classic regressions, whose results might be affected by multicollinearity. In addition, because of the absence of robust economic theory on tourism behavior, regressor selection is often left to researcher's choice when not driven by non-optimal automatic criteria. Scad-elastic net is an OLS model that accounts for both these problems by including two types of parameters constraints, namely the smoothly clipped absolute deviation …

Assessing the Performance of the Italian Translations of Modified MEIM, EIS and FESM Scales to Measure Ethnic Identity: A Case Study
2023
Measuring the ethnic identity of linguistic minorities is a research problem which can be tackled departing from a clear operational definition of the construct. This paper will present the performance of the Italian translations of various scales widely used in the relevant literature, which have been modified for the aims of this study and used in research conducted in 2016 in the ArberesheMunicipalities of Piana degli Albanesi and Santa Cristina Gela (Province of Palermo). These scales consist of modifications of the Multigroup Ethnic Identity Measure (MEIM), Ethnic Identity Scale (EIS) and Familial Ethnic Socialization Measure (FESM). The psychometric properties were analysed for all th…
Net satisfaction: a different point of view on the measurement of subjective well-being
2013
Starting from the baffling relationship between satisfaction and importance in the evaluation of subjective well-being, this paper presents a new definition of satisfaction useful to build a composite index of subjective well-being. The index is proven on data from European Quality of Life Survey 2007 and compared with two of the standard literature approaches to measure satisfaction taking into account importance weighting.
Women as main earners in Europe
2014
This paper conducts a cross-sectional empirical research aimed at documenting that couples with women as main earners represent a non-negligible share of the European populations today. We identify the socio-demographic characteristics of couples with women as main earners in comparison to couples with men as main earners and couples with equal-earners. We undertake a comparative and cross-temporal approach using micro-level survey data for 18 European countries from the European Social Survey and two years, 2004 and 2010, covering the period before and during the economic crisis.
Measuring tourism seasonality across European countries
2018
Abstract This paper will propose a general approach for the analysis and measurement of seasonality in tourism, based on an analysis of the pattern of seasonal swing, as a preliminary step for the assessment of seasonal amplitude. The seasonality of tourism demand across European countries will be analyzed and clusters of countries identified, which are based on a similarity of their seasonal pattern. After discussing the limitations of the most frequently used indices employed in the tourism literature, a new index for measuring seasonality in tourism will be suggested in order to measure seasonal amplitude. The latter takes into account the ordinal and cyclical structures of seasonal vari…
