Abstract The analysis of multiple population structures (biodemographic, genetic and socio-cultural) and their inter-relations contribute to a deeper understanding of population structure and population dynamics. Genetically, the population structure corresponds to the deviation of random mating conditioned by a limited number of ancestors, by restricted migration in the social or geographic space, or by preference for certain consanguineous unions. Through the isonymic method, surname frequency and distribution across the population can supply quantitative information on the structure of a human population, as they constitute universal socio-cultural variables. Using documentary sources to undertake the Doctrine of Belén’s (Altos de Arica, Chile) historical demography reconstruction between 1763 and 1820, this study identified an indigenous population with stable patronymics. The availability of complete marriage, baptism and death records, low rates of migration and the significant percentage of individuals registered and constantly present in this population favoured the application of the isonymic method. The aim of this work was to use given names and surnames recorded in these documentary sources to reconstruct the population structure and migration pattern of the Doctrine of Belén between 1750 and 1813 through the isonymic method. The results of the study were consistent with the ethno-historical data of this ethnic space, where social cohesion was, in multiple ways, related to the regulation of daily life in colonial Andean societies.

SummaryThis paper tests the hypothesis that the inverse relationship between population density and migration distances in pre-industrial Europe results from variation in the social class composition of communities. Data from two pyrenean valleys in Navarre, spain, provide support for the hypothsis. Further effect on mugration distances may result from vatiation in the settlement pattern of communities. Seasonal movement associated with certain occupations seems to be unimportant.

Este trabalho apresenta parte dos resultados de uma pesquisa, que estudou o percurso vivido por professoras migrantes, que atuam em escolas públicas no município de Campo Verde, interior do Estado de Mato Grosso. Nos estudos foram consultadas fontes documentais e orais, na medida em que a investigação procurou situar e refletir o processo de ocupação da cidade, bem como as implicações humanas e ambientais atinentes a esse processo. Nesse espaço geográfico e de sociabilidade, também considerada fronteira humana, são reproduzidas formas de convivências pacíficas e solidárias, mas ainda são lugares segregadores, nos quais estereótipos, preconceitos e discriminação permeiam as relações sociais, principalmente, com a população autóctone, como os índios e os negros. A partir da reflexão acerca da forma de ocupação e organização da cidade, buscou-se responder às questões étnico-raciais que permeiam as relações sociais e educativas da cidade, muitas vezes, conflituosas no cotidiano de alunos, pais e professores. Os resultados da pesquisa contribuíram, também, para uma reflexão sobre os motivos, que impulsionaram o processo de migração e a necessidade de maior preservação dos recursos naturais frente ao crescimento da monocultura.Palavras-chave: Migração. Ocupação. Convivências e Conflitos.AbstractThis paper presents part of the results of a survey, which studied the route experienced by migrant teachers working in public schools in the municipality of Campo Verde, interior of the state of Mato Grosso. In the studies oral and documentary sources were consulted , to the extent that the research sought to situate and reflect the process of occupancy of the city, as well as the human and environmental implications related to this process. In this geographic space and sociability, also considered human frontier, are reproduced forms of peaceful cohabitation and solidarity, but there are still segregating places , in which stereotypes, prejudices and discrimination permeates the social relations, especially, with the indigenous population, such as the Indians and blacks. From the reflection about the form of occupation and organization of the city, it was sought to respond to the ethnic-racial issues that permeate the social relations and educational activities of the city, many times, conflicting in the everyday life of students, parents and teachers. The results of the research contributed also to a reflection on the reasons that drove the migration process and the need for greater preservation of natural resources before the monoculture growth.Keywords: Migration.

Demographic indicators are an essential element in considering various problems in the social economy, such as predicting economic fluctuations and establishing policies. Although literature extensively discusses the growth of the world population or issues pertaining to its aging, it has given little to no attention to population structures and transition patterns while considering compositional data problems. This study considers the characteristics of compositional data to examine the transition of the world population structure. The Aitchison distance examines the similarity of the world population structure from 1990 to 2080 and that of countries and regions in 2015, and creates maps to illustrate the results. Accordingly, the results identified the following countries and regions as epitomes of the world’s population structure through different periods: India, Northern Africa and South Africa, in the 1990s, South America in 2015 to 2030, Oceania and Northern America in 2040, Uruguay and Puerto Rico in 2050 to 2060, and Italy and Japan in the distant future.

Given the high level of global mobility, pandemics are likely to be more frequent, and with potentially devastating consequences for our way of life. With COVID-19, Australia is in relatively better shape than most other countries and is generally regarded as having managed the pandemic well. That said, we believe there is a critical need to start the process of learning from this pandemic to improve the quantitative information and related advice provided to policy makers. A dispassionate assessment of Australia’s health and economic response to the COVID-19 pandemic reveals some important inadequacies in the data, statistical analysis and interpretation used to guide Australia’s preparations and actions. For example, one key shortcoming has been the lack of data to obtain an early understanding of the extent of asymptomatic and mildly symptomatic cases or the differences across age groups, occupations or ethnic groups. Minimising the combined health, social and economic impacts of a novel virus depends critically on ongoing acquisition, integration, analysis, interpretation and presentation of a variety of data streams to inform the development, execution and monitoring of appropriate strategies. The article captures the essential quantitative components of such an approach for each of the four basic phases, from initial detection to post-pandemic. It also outlines the critical steps in each stage to enable policy makers to deal more efficiently and effectively with future such events, thus enhancing both the social and the economic welfare of its people. Although written in an Australian context, we believe most elements would apply to other countries as well.

ABSTRACT Unbiased estimates of θ = 4Nµ in a random mating population can be based on either the number of alleles or the average number of nucleotide differences in a sample. However, if there is population structure and the sample is drawn from a single subpopulation, these two estimates of θ behave differently. The expected number of alleles in a sample is an increasing function of the migration rates, whereas the expected average number of nucleotide differences is shown to be independent of the migration rates and equal to 4N  Tµ for a general model of population structure which includes both the island model and the circular stepping-stone model. This contrast in the behavior of these two estimates of θ is used as the basis of a test for population subdivision. Using a Monte-Carlo simulation developed so that independent samples from a single subpopulation could be obtained quickly, this test is shown to be a useful method to determine if there is population subdivision.

Exerted Pressure

Industrial cleaning shares some common features across countries. Institutions for collective wage regulation are fragile, the market is highly price-sensitive and skewed competition has exerted pressure on wages and conditions. Increased cross-border mobility of labour and enterprises after EU enlargement brought new sources of competitive pressure, which was amplified by the subsequent economic crisis. We study changes in collective regulation in industrial cleaning in Denmark, Germany, Norway and the UK since the turn of the century, and find that the social partners have responded differently to the challenges. We discuss these responses in the light of national differences in industrial relations regimes and the regulatory tools available for the organized actors.

A more realistic way to describe a model is the use of intervals which contain the required values of the parameters. In practice we estimate the parameters from a set of data and it is natural that they will be in confidence intervals. In the present study, we study Non-Homogeneous Markov Systems (NHMS) processes for which the required basic parameters are in intervals. We call such processes Non-Homogeneous Markov Set Systems (NHMSS). First we study the set of the relative expected population structure of memberships and we prove that under certain conditions of convexity of the intervals of the parameters the set is compact and convex. Next, we establish that if the NHMSS starts with two different initial distributions sets and allocation probability sets under certain conditions, asymptotically the two expected relative population structures coincide geometrically fast. We continue proving a series of theorems on the asymptotic behavior of the expected relative population structure of a NHMSS and the properties of their limit set. Finally, we present an application for geriatric and stroke patients in a hospital and through it we solve problems that surface in an application.

Biogeographical Ancestry

Abstract Detecting population structure and estimating individual biogeographical ancestry are very important in population genetics studies, biomedical research and forensics. Single-nucleotide polymorphism (SNP) has long been considered to be a primary ancestry-informative marker (AIM), but it is constrained by complex and time-consuming genotyping protocols. Following up on our previous study, we propose that a multi-insertion-deletion polymorphism (Multi-InDel) with multiple haplotypes can be useful in ancestry inference and hierarchical genetic population structures. A validation study for the X chromosome Multi-InDel marker (X-Multi-InDel) as a novel AIM was conducted. Genetic polymorphisms and genetic distances among three Chinese populations and 14 worldwide populations obtained from the 1000 Genomes database were analyzed. A Bayesian clustering method (STRUCTURE) was used to discern the continental origins of Europe, East Asia, and Africa. A minimal panel of ten X-Multi-InDels was verified to be sufficient to distinguish human ancestries from three major continental regions with nearly the same efficiency of the earlier panel with 21 insertion-deletion AIMs. Along with the development of more X-Multi-InDels, an approach using this novel marker has the potential for broad applicability as a cost-effective tool toward more accurate determinations of individual biogeographical ancestry and population stratification.

Many in Hong Kong voice concerns about the fate of Cantonese, including nativists (“localists”) and the general public. Guangzhou is seen as a harbinger of diminishing Cantonese in Hong Kong. News and commentaries paint a gloomy picture of Cantonese in Guangzhou. Yet rarely do we read about surveys on the range of Cantonese use and identity in Guangzhou. Neither do we see analyses on how the social context differences between Hong Kong and Guangzhou may have contributed to the two cities’ unique language situations. Our study delineates the Guangzhou and Hong Kong language situations, comparing mother tongues, ordinary languages, and language attitudes. Cantonese is unrivalled in Hong Kong and remains vital in Guangzhou. We put the two cities’ different use frequency and proficiency of Cantonese and Putonghua (“Mandarin”) in the sociocultural context of motivation and migration. We conclude that some claims of diminishing Cantonese are unsupported. We also address how likely it is that Cantonese will diminish or even be replaced in Hong Kong.

The political economy of Irish work and welfare has dramatically changed over recent decades. Since the 1980s, Ireland has experienced two periods of high unemployment followed by two periods of full employment. Alongside this, we see considerable shifts in both the sectoral composition of the workforce and in the institutional architecture underpinning the labour market. Focusing on the last decade, this chapter contextualizes the Irish labour market in the Irish growth model, highlighting issues including occupational upgrading, low pay, gender composition, and migration. The chapter then explores links between this employment structure and Ireland’s changing welfare regime. It considers recent institutional changes, as the welfare regime shifted to a work-first form of activation, and the long-term sustainability of the social protection system. The chapter concludes by highlighting what we see as the core challenges for the political economy of work and welfare in Ireland.
