  2. 1. A contribution to population dynamics in space

    Author : Nikias Sarafoglou; Å.E. Andersson; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population growth; population age structure; migration; labour market; housing market; production function; stochastic differential equations; partial differential equations;

    Abstract : Population models are very often used and considered useful in the policy-making process and for planning purposes. In this research I have tried to illuminate the problem of analysing population evolution in space by using three models which cover a wide spectrum of complementary methodologies:a The Hotell.

  4. 2. Population genetic history and patterns of admixture : Examples from northeastern and southern Africa

    Author : Nina Hollfelder; Mattias Jakobsson; Michele Ramsay; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population structure; genetic admixture; genomic variation; Africa; population genomics; lactase persistence; sex-biased admixture; human evolutionary genetics; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Abstract : The origin of humans lies in Africa, as has been shown by archaeology, paleontology and genetics. Here, we can find the largest genetic diversity and the deepest split among human populations. African genetic diversity has been shaped by a long and complex history. READ MORE

  5. 3. Biomarkers of vascular function and structure in young healthy adults

    Author : Paul Pettersson-Pablo; Anita Hurtig-Wennlöf; Torbjörn Nilsson; Lars Breimer; Anders Larsson; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; vascular function; vascular structure; body composition; age; inflammation; clinical chemistry; biomarker;

    Abstract : Atherosclerosis is a disease affecting the blood vessels in the body. Its pathophysiologic mechanisms involve infiltration of the vessel walls by fatty matter and immune cells. This process is slow, starting in childhood but typically not manifesting as symptomatic disease until late adulthood (after 60 years of age). READ MORE

  6. 4. Demographic History and Adaptation in African Populations

    Author : Mário Vicente; Carina Schlebusch; Mattias Jakobsson; Lluis Quintana-Murci; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; African demography; human evolutionary genetics; population structure; population admixture; genetic adaptation;

    Abstract : Africa is the continent where modern humans originated and yet, African demographic history remains largely unknown. Through analyzing the genetic composition of extant and extinct individuals, it is possible to reveal signals of past demographic history and adaptation. READ MORE

  7. 5. Live Longer, Work Longer? Evidence from Sweden’s Ageing Population

    Author : Haodong Qi; Centrum för ekonomisk demografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Employment; Retirement Behavior; Working Life; Labor Supply; Pension Reform; Financial Incentives; Population Ageing;

    Abstract : Sweden’s elderly population is growing, propelled by a continuous decline in old-age mortality, while coupled with a persistent replacement level fertility. This changing age structure increases the per worker cost of providing a given age-vector of per capita benefits, encompassing costs for pensions, health care, and all other type of old-age welfare services, which presents a looming challenge for the welfare state to sustain its social transfer system.
