Sedentariness and weight status related to SES and family characteristics in Italian adults: exploring geographic variability through multilevel mode…

2017

Aim: In this study, our aim was to assess the prevalence of sedentariness and overweight/obesity, two modifiable risk factors for non-communicable diseases (NCDs), and to investigate the geographic variability in their association with socio-economic status (SES) and family characteristics in Italian adults. Methods: The Multipurpose Survey on Health Conditions and the Recourse to Health Services (MSHC), 2012/2013 edition, conducted by the National Institute of Statistics was used as data source. The sample for this study included 99,479 interviewed people aged 18 and over, which are representative of about 50 million persons. For the scope of this analysis, data were considered as individ…

The Cross-Level Moderation Effect of Resource-Providing Leadership on the Demands—Work Ability Relationship

2021

Employees in female-dominated sectors are exposed to high workloads, emotional job demands, and role ambiguity, and often have insufficient resources to deal with these demands. This imbalance causes strain, threatening employees’ work ability. The aim of this study was to examine whether resource-providing leadership at the workplace level buffers against the negative repercussions of these job demands on work ability. Employees (N = 2383) from 290 work groups across three countries (Germany, Finland, and Sweden) in female-dominated sectors were asked to complete questionnaires in this study. Employees rated their immediate supervisor’s resource-providing leadership and also self-reported …

Consumption Patterns and Family Life-Cycle. Some Evidence from Italy

2015

As a social and economic entity the family is changing continuously. Changes in family size and composition have significant effects on the family decision making process. The Italian context is an interesting subject for research as a result of the impact of demographic and economic changes in the early 2000s on new family structures and economic behaviour. Furthermore, in Italy in contrast to the past, both men and women are aiming for job security and satisfaction before marrying and starting a family. In the light of that, it is particularly interesting to investigate if consumption behaviour changes along the life cycle stages. Considering different family life stages enables us to exp…

Testing for convergence from the micro-level

2011

Empirical convergence analysis is typically envisaged from a macro aggregate perspective. However, researchers have recently highlighted how investigating convergence at the disaggregate level may yield interesting insights into the convergence debate. In this paper, we suggest an approach that allows exploiting large micro panels to test for convergence. Compared to the traditional convergence analysis, this approach allows obtaining beta- and sigma-like convergence parameters for both the micro and the macro level of interest. We provide a practical example that analyses productivity convergence across firms and provinces using a large sample of Italian firms.

Estimating Verdoorn law for Italian firms and regions

2011

In empirical regional economics, returns to scale are typically estimated at the regional level in search for evidence on alternative theories of growth and agglomeration. However, returns to scale may also have a firm-level dimension. In this paper, we exploit micro level data and estimate the dynamic Verdoorn law in a multilevel-setting, where returns to scale are obtained simultaneously for the micro and the regional level. Using Italian firm-level data and the NUTS-3 level of aggregation, we estimate the classic and augmented versions of Verdoorn law for the manufacturing sector, and the rest of the economy for comparison. Our results show that increasing returns to scale co-exist at bo…

The Effect of Education on Under-Five Mortality: Individual and Community-Level Effects in Bangladesh

2019

This paper investigates the relationship between parental education and child survival, considering both the influence of the maternal and paternal educational level and the influence of communitylevel male and female education on under-five mortality. The research is focused on Bangladesh, a country where the impressive decline in the under-five mortality rate between 1990 and 2015 was attributed both to female empowerment and to the increase in the general level of education in the country. Using the Bangladesh Demographic and Health Survey from 2014, this paper investigates both the effect of individual-level parental education and of community-level education on under-five mortality, th…

The Multilevel Model in the Computer-Generated Appraisal: A Case in Palermo

2017

The construction of a mass appraisal model requires the preliminary study of the real estate market, the sampling of sold properties, the development of a forecasting model and the verification of the appraisal results. They are generally computerised methods, that work with geo-referenced data. This experimental work has proceeded to build a mass appraisal model, collecting a data sample of sales of apartments in the city of Palermo, in the five years 2008–2012, using a multivariate statistical model (multilevel), testing the results and providing the operating applications in a scheme of online real estate valuations.

Modelling students' mobility in Italy: an analysis of the determinants by combining individual and aggregated data

The migratory phenomenon consisting in the enrolment of some students in a University different from the one nearest to their place of origin goes under the name of students’ mobility (SM). This phenomenon can be studied for different territorial aggregations, depending on the aims and the availability of data. In Italy several analyses have been carried out to detect the determinants of such a phenomenon. Two approaches are mostly followed. The former considers the analysis of aggregate data (AD) flows, and it is aimed at detecting the characteristics of the Universities and the territories in which they are situated, the latter analyzes the determinants of SM on the grounds of the student…

Resident’s Perceptions of Tourism Influence on Quality of Life: a Multilevel approach.

2015

This study aims to evaluate whether individual perceptions of tourism’s effects on quality of life (TQOL) are related to the degree of tourism activity in the host community, as well as to residents’ personal characteristics, by a multilevel model. Data from a survey performed in Sicily have been analyzed. The model revealed that the level of tourism activity have an influence on the way residents perceive the effect tourism in their community, as measured by TOQL index.

Building up adjusted indicators of students' evaluation of university courses using generalized item response models

2012

This article advances a proposal for building up adjusted composite indicators of the quality of university courses from students’ assessments. The flexible framework of Generalized Item Response Models is adopted here for controlling the sources of heterogeneity in the data structure that make evaluations across courses not directly comparable. Specifically, it allows us to: jointly model students’ ratings to the set of items which define the quality of university courses; explicitly consider the dimensionality of the items composing the evaluation form; evaluate and remove the effect of potential confounding factors which may affect students’ evaluation; model the intra-cluster variabilit…
