Entre los más altos de España. El estado nutricional en las Canarias occidentales: cohortes masculinas de 1860-1915

Abstract Objetivo: analizamos la dinámica del estado nutricional en las Canarias con datos de la altura masculina durante la segunda mitad del siglo xix y su dimensión en el contexto español.Métodos: con datos del reclutamiento militar, hacemos una estimación de la talla promedio masculina en edades de 19-21 años por cohortes de nacimiento para el…

Sibhsip size, height and cohort selection: a methodological approach

Abstract This article deals with the historical relationship between the number of siblings in a family or household and height, a proxy for biological living standards. Ideally, this relationship is better assessed when we have evidence on the exact number of siblings in a family from its constitution onwards. However, this generally requires applying family…

Month of birth and height. A case study in rural Spain

Abstract Introduction.- Season of birth correlates to a wide range of health conditions throughout life measured by anthropometrics. This study explores whether the month of birth and weather during gestation influence male adult height, based on Spain’s rural population before the end of the modernization process. Methods.- The database of heights (N = 16.266) is composed of…

Growing taller unequally? Adult height and socioeconomic status in Spain (Cohorts 1940–1994)

Abstract Socioeconomic inequalities and their evolution in different historical contexts have been widely studied. However, some of their dimensions remain relatively unexplored, such as the role played by socioeconomic status in the trajectory of biological living standards, especially net nutritional status. The main objective of this article is to analyze whether the power of socioeconomic…

Symbolic Analysis Applied to the Specification of Spatial Trends and Spatial Dependence

Abstract This article provides symbolic analysis tools for specifying spatial econometric models. It firstly considers testing spatial dependence in the presence of potential leading deterministic spatial components (similar to time-series tests for unit roots in the presence of temporal drift and/or time-trend) and secondly considers how to econometrically model spatial economic relations that might contain…

The impact of geographical factors on churn prediction: an application to an insurance company in Madrid’s urban area

Abstract Geography has previously been noted as a decisive factor in business literature. This paper provides evidence of the significant role geography plays in customer lapse behaviour in an urban environment. This novel approach is based on the idea that the customers who cancel all policies and leave the company are not randomly distributed; rather,…

Spatial models for online retail churn: Evidence from an online grocery delivery service in Madrid

Abstract This paper presents evidence of the significant role that geography plays in customer churn behaviour in online retail. In an urban environment, mimetic behaviours are found to affect nearby individuals. This novel approach is based on the idea that customer churn is not randomly distributed across the map. This paper analyses more than 2,000…

Biological Well-Being and Inequality in Canary Islands: Lanzarote (Cohorts 1886–1982)

Abstract Developments in anthropometric history in the Iberian Peninsula have been remarkable in recent decades. In contrast, we barely know about the behavior of insular population groups and infants’ and adults’ growth during the nutritional transition in the Canary Islands. This paper analyzes the height, weight and body mass index of military recruits (conscripts) in…

A Parallel Algorithm for Matheuristics: A Comparison of Optimization Solvers

Abstract Metaheuristic and exact methods are one of the most common tools to solve Mixed-Integer Optimization Problems (MIPs). Most of these problems are NP-hard problems, being intractable to obtain optimal solutions in a reasonable time when the size of the problem is huge. In this paper, a hybrid parallel optimization algorithm for matheuristics is studied….

Using non-radial DEA to assess school efficiency in a cross-country perspective: An empirical analysis of OECD countries

Abstract In this paper we use data from OECD countries participating in PISA 2012 to assess the efficiency of schools in a cross-country framework. In the analysis, and in contrast to previous applications, we consider that schools might concentrate their efforts on improving the results in one dimension of the educational output to a greater…
