A Comparison between General Population Mortality and Life Tables for Insurance in Mexico under Gender Proportion Inequality || Una comparación entre la mortalidad de la población general y las tablas de vida de los seguros en México ante porcentajes desiguales de género [PDF]

Revista de Métodos Cuantitativos para la Economía y la Empresa, 2013
We model the mortality behavior of the general population in Mexico using data from 1990 to 2009 and compare it to the mortality assumed in the tables used in Mexico for insured lives.

Bayesian Demographic Modeling and Forecasting: An Application to U.S. Mortality [PDF]

We present a new way to model age-specific demographic variables with the example of age-specific mortality in the U.S., building on the Lee-Carter approach and extending it in several dimensions.

Heart Rate as an Indicator of Stress in Gotland's Russ Horses

Zoo Biology, EarlyView.
ABSTRACT Animal welfare concerns both the physical and mental wellbeing of animals so the assessment of animals kept in captivity, for example zoos, is important and necessary both legally and ethically. Good welfare is especially vital when breeding endangered species as stress impairs reproductive investment.

Spatiotemporal dynamics and machine learning‐based prediction of above‐ground biomass in the Indus Delta mangroves

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mangrove forests are important blue carbon ecosystems, yet long‐term above‐ground biomass (AGB) dynamics in arid deltaic systems remain poorly understood. Here, we integrated field‐derived AGB data with multisource remote sensing and machine learning models (random ...

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

Journal of Animal Ecology, EarlyView.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

How the co-integration analysis can help in mortality forecasting. [PDF]

series of age-specific log-mortality rates as a sum of an independent of time age-specific component and a bilinear term in which one of the component is a time-varying parameter reflecting general change in mortality and the second one is an age ...

The role of longevity risk in Hungary [PDF]

, 2016
In this paper, I analyze the role of longevity risk in Hungary in the public pension system and the life annuity segment of the life insurance market, which are two primary financial sectors of relevance to this special type of actuarial risk, using ...

The spatial distribution and origin of the FUV excess in early-type galaxies

, 2011
We present surface photometry of a sample of 52 galaxies from the GALEX and 2MASS data archives, these include 32 normal elliptical galaxies, 10 ellipticals with weak Liner or other nuclear activity, and 10 star forming ellipticals or early-type spirals.

Towards an anthropology of acquisition: ‘How did you get that?’ Vers une anthropologie de l'acquisition : « Où as‐tu trouvé ça ? »

Journal of the Royal Anthropological Institute, EarlyView.
The production‐distribution‐consumption triad has structured how anthropologists understand exchange for roughly a century. This article argues for expanding this triad to include an explicit focus on acquisition – the systems, processes, and practices of acquiring.
