Estimation of the Combined Effects of Ageing and Seasonality on Mortality Risk: An Application to Spain

2021

Abstract Despite the overwhelming evidence that shows the persistence of intra-annual variations on demographic events (deaths, birth dates and migration flows), life tables are computed and provided on an annual basis. This paper develops a new estimator for estimating sub-annual death rates that, considering the exact moment of occurrence (exact age and day) of events, concurrently accounts for ageing and calendar fluctuations. This paper also shows how modelling the intra-annual variations of death rates, through specific seasonal–ageing indexes, can be used as a tool for constructing new sub-annual tables from annual tables. This new methodology is exemplified using a real database of S…

Promoting Research and Landscape Experience in the Management of the Archaeological Networks. A Project-Valuation Experiment in Italy

2020

Archaeological sites are part of the history and identity of a community playing a strategic role on the different scales of the cultural and economic common life. Whereas on the one end the most famous archaeological sites attract huge flows of tourists and investment, on the other hand, many minor archaeological sites remain almost ignored and neglected. This study proposes a project-evaluation approach devoted to the &ldquo

Generating a Located Synthetic Population of Individuals, Households, and Dwellings

2017

Some of the new approaches in urban modeling, such as multi-agent systems (MAS) or activity-based models (ABM), require inputs in the form of disaggregated individual data. But for privacy protection reasons, such data is seldom available at this level. One way to get around this obstacle is to generate a synthetic population. This paper presents a method for generating a population from fully aggregated socio-demographic and geographic data. Based on French examples, this method can be reproduced anywhere in the country providing a relevant linkage between the characteristics of agents and those of urban spaces. The proposed method is subdivided into two steps. First, a population of agent…

Theoretical space-time modelling of the diffusion of raw materials and manufactured objects

2013

International audience; Workgroup 3 of ArchaeDyn II programme focuses its study on the diffusion systems of ancient products. In order to be able to structure data in GIS in an appropriate way, we propose a general theoretical modelling integrating the different components of the diffusion systems, and identifying their interactions and the factors affecting the location of products and their transfers. Three dimensions are considered: the Time, the Space and the Function of places. A product's pathway can be apprehended efficiently by distinguishing spatial entities as well as functional entities. This modelling highlights the fact that the approach through the simple notion of "site" is n…

The soil map of Italy: a hierarchy of geodatabases, from soil regions to sub-systems

2014

This paper is aimed at showing the organization of the national soil information system managed by the Agriculture Research Council of Italy (Soil Information System of Italy, SISI). The available soil geodatabases for the whole of Italy are those of the soil regions (1:5,000,000), subregions (1:1,000,000), and systems (1:500,000), while the soil subsystems geodatabase (1:250,000) is available for most part of Italy.

Micro evidence for sources of innovation in European countries

2012

This paper investigates sources of product or process innovation, such as investments in research and development, machinery, personnel training and management systems, by examining microdata from eight European countries. We pay particular attention to the effect of research and development in favouring the absorption of new technologies, i.e. the absorptive capacity. Significant positive effects of each source on both product and process innovations are found. Significant evidence of positive absorptive capacity emerges only in firms with low predicted probabilities of introducing innovation.

Inequalities and the Impact of Job Insecurity on Health Indicators in the Spanish Workforce

2020

In a context of high job insecurity resulting from social deregulation policies, this research aims to study health and substance abuse inequalities in the workplace from a gender perspective. To this end, a transversal study was carried out based on microdata from the National Health Survey in Spain&mdash

Working while studying: does it lead to greater attachment to the regional labour market?

2017

This chapter studies the link between working while studying and migration. Understanding this link is important because policy-makers are often calling for actions that would cut down the hours students spend on working to shorten the graduation time. The chapter’s analysis focuses on graduates from Finnish universities, polytechnics and vocational schools in 1991–2004. It uses rich register-based longitudinal microdata constructed by Statistics Finland, and find a negative relationship between working while studying and graduate migration. An increase in student employment can thus partly explain the decline in geographic mobility among Finnish graduates from higher education.

Taking non-manuality into account in collecting and analyzing Finnish Sign Language video data

2014

This paper describes our attention to research into non-manuals when collecting a large body of video data in Finnish Sign Language (FinSL). We will first of all give an overview of the data-collecting process and of the choices that we made in order for the data to be usable in research into non-manual activity (e.g. camera arrangement, video compression, and Kinect technology). Secondly, the paper will outline our plans for the analysis of the non-manual features of this data. We discuss the technological methods we plan to use in our investigation of non-manual features (i.e. computer-vision based methods) and give examples of the type of results that this kind of approach can provide us…
