Abstract:

In India, due to the lack of age-specific death and birth data, direct calculation of Net Reproduction Rate is not possible, particularly at the district level. Also, conventional Net Reproduction Rate and intrinsic growth rate measures are not suitable for populations affected by migration. The present study attempts to recapture the scenario of migration in the districts of two diverged states of India—Kerala and Assam—by estimating the Net Reproduction Rates before and after allowance for migration. The study also attempts to assess the speed of population growth of these districts from the

Abstract:

The literature on the impacts of heterogeneity and selection in population analysis has been limited largely to the conventional unistate perspective in which only decrements are considered; and their temporal (selectivity) impacts on independent subpopulations examined. In this paper, the focus is on the evolutionary dynamics of (multistate) multiregional populations whose interdependent subpopulations can experience increments as well as decrements. It is shown that in such instances migration rates that are not true occurrence-exposure rates are ambiguous, because they depend on the relativ

Abstract:

International labour migration is mainly promoted by economic interests. This paper focuses on the period before and after the economic crisis and puts together important facts regarding motivation to labour migration and provides explanations of its causes and impacts on the macroeconomic level. The economic explanation why is migration so severely restricted is that migration policies are essentially distributive tools, aiming at reducing negative effects of migration on wages and unemployment among natives and moreover, we may stress out the gradualist tendencies of migration and such migra

This paper uses an OLG-CGE model for the UK to illustrate the long-term effect of migration on the economy. We use the current Conservative Party migration target to reduce net migration “from hundreds of thousands to tens of thousands” as an illustration. Achieving this target would require reducing recent net migration numbers by a factor of about 2. We undertake a simulation exercise to compare a baseline scenario, which incorporates the principal 2010-based ONS population projections, with a lower migration scenario, which assumes that net migration is reduced by around 50 per cent.

We analyze the implications of pollution and migration externalities on the optimal population dynamics in a spatial setting. We focus on a framework in which pollution affects the mortality rate and decreases utility, while migration occurs within the spatial economy. Agents optimally determine their fertility rate which, along with pollution-induced mortality and spatial migration, determines the net population growth rate. This setting implies that human population follows an endogenous logistic-type dynamics where fertility choices determine what the optimal limit of human population will

We find that the onset to crevasse formation, and by inference the onset to streaming flow, has migrated upstream over time at a mean rate of 230(16) m a−1. A possible cause for that migration is changes in net basal friction due to changes in basal water production rate and storage.

Using ordinary least square regression method, the results indicate that the level of unemployment, migrants’ remittances and population growth are the key determinants of emigration from Nigeria to other countries, statistically significant at 0.01 level.In a country where unemployment rate is very high, this movement is likely to help in reducing pressures on the labour market. Migrants’ remittances might also help in alleviating poverty within households.

Documented shoreline changes using historical surveys and vertical aerial photographs show that the barrier had little in the way of net change in position between 1883 and 1939, including the impact of the 1938 hurricane. The barrier retreated rapidly between 1945 and 1975, driven by both tropical and extra-tropical storms. The shoreline position has been largely static since 1975. The removal of the foredune during the 1938 hurric

Abstract:

SUMMARY Although the homing migration of Pacific salmon is well documented, the swimming behaviour of the returning salmon has been poorly described, principally as a result of the difficulties encountered in monitoring salmon behaviour in the sea. The present study describes the use of a recently developed electronic data logger to obtain simultaneous recordings of the swimming speed, depth, fin-beating activity and body angle of free-ranging chum salmon Oncorhynchus keta during their homing migration in coastal waters. Chum salmon migrated horizontally at speeds of 1.5–3.0 km h–1. The gross

Abstract:

The article provides an analysis of the current level of migration to and from the Kaliningrad region. The article focuses on the impact of migration on the replacement of the natural population decline and its age and sex structure. The data on the age and sex of migrants and the population of municipalities of the Kaliningrad region in 2011-2017 were used in the analysis. The author has built a typology of migration trends in the region. The main classifying feature was the criterion of migration intensity in different age and gender groups, which was estimated using the net migration rate.

Abstract:

Mexico-U.S. migration has dramatically changed in the past three decades: the pronounced increasing flow of the 1990s stalled in the 2000s and a zero net migration rate was officially reported in 2010. Deportations and economic crisis have been discussed as the underlying reasons of this change. In the context of involuntary movements, I evaluate the labor market incorporation of return migrants with respect to non-movers and internal migrants in Mexico between 2000 and 2010. Using the Mexican Census samples, I found that the reduction on return migrants’ earnings is associated to changes in b

Abstract:

How seasonal migration originated and impacted diversification in birds remains largely unknown. Although migratory behaviour is likely to affect bird diversification, previous studies have not detected any effect. Here, we infer ancestral migratory behaviour and the effect of seasonal migration on speciation and extinction dynamics using a complete bird tree of life. Our analyses infer that sedentary behaviour is ancestral, and that migratory behaviour evolved independently multiple times during the evolutionary history of birds.

SummaryData from the 1985–86 Japanese census are analysed to explore the determinants of the divorce rates in Japan's forty-seven prefectures, using two theoretical models: (a) the social integration model, which is shown to have a greater utility in predicting Japanese divorce levels than (b), the human capital model. Female emigration patterns play a significant role in affecting the divorce rate. Population increase and net household income are also important predictors of the Japanese divorce rate and urbanization has a great influence in modern Japan. Demographic and aggregate variables s

From the mid-1950s through the mid-1980s, migration between Mexico and the United States constituted a stable system whose contours were shaped by social and economic conditions well-theorized by prevailing models of migration. It evolved as a mostly circular movement of male workers going to a handful of U.S. states in response to changing conditions of labour supply and demand north and south of the border, relative wages prevailing in each nation, market failures and structural economic changes in Mexico, and the expansion of migrant networks following processes specified by neoclassical ec

This paper aims to provide descriptive results about demographic trends (natality, mortality, and migration) and their effect on age structure in Romania in the past 30 years. We focus on analysing rural areas, since, while having a negative natural growth and negative net external migration values, internal migration has further affected rural areas by increasing the rate of population decline in many localities. Apart from describing rural areas at a general level, we also differentiate various rural localities according to two criteria, namely inclusion in functional urban areas of every co

The aerial photographs show the movements of 51 different sand-bank crestlines, and the morphological characteristics of both sand banks and sandwaves. From the orientation of sandwave crests to the sand-bank crestlines, zones of ebb- and flood-dominance in sand-transport direction are distinguished. The migration directions of the sand banks are predicted by considering the cross-sectional asymme

Egg recruitment quantifies the relative importance of realized fecundity and migration rates in the population dynamics of highly mobile insects. We develop here a formal context upon which to base the measurement and interpretation of egg recruitment in population dynamics of eastern and western spruce budworms, two geographically separated species that share a very similar ecology. Under most circumstances, per capita egg recruitment rates in these budworms are higher in low-density populations and lower in high-density populations, relative to the regional mean: Low-density populations are

Growth factors stimulate sustained cell migration as well as inducing select acute motility-related events such as membrane ruffling and disruption of focal adhesions. However, an in-depth understanding of the characteristics of sustained migration that are regulated by growth factor signals is lacking: how the biochemical signals are related to physical processes underlying locomotion, and how these events are coordinately influenced by interplay between growth factor and matrix substratum signals. To address these issues, we studied sustained migration of NR6 fibroblasts on a complex human m

The aim of the paper is to evaluate the development of international migration in relationship to the recent economic situation in member countries of the European Union using quantitative methods including cluster analysis. The number of immigration in Europe has declined since the start of the global recession. The main reason was the decrease of demand in many sectors of the national economy, for instance the demand for retail and construction workers. Despite the drop in new immigration, labour markets of the EU countries were hit very severely. Unemployment rates in the most of European c

The study utilized population data from the US Census Bureau from 1990 to 2015. The method involved first estimating mortality rates for countries with negligible net migration and then applying these rates to countries with matching mortality profiles, where it is reasonable to assume that migration is negligible for children under the age of 5 years.

The rate of rise of the TSL during the ablation season on a glacier where the balance gradient is known provides a measure of the snow ablation rate. On both LCG and MG, snow pits were completed in regions that the TSL subsequently transects. This further provides a direct mea

A 100 g-tonne geotechnical centrifuge was used to study the long-term migration of a contaminant and radioactive tracer through a saturated soil medium. The use of the centrifuge simulates the acceleration of traveltime in the prototype, which is N times larger than the model, by N2, where N is the desired g level. For a 5 h run at 60 g, the test modelled a migration time of about 2 years for a prototype 60 times larger than the small-scale model tested. Iodine 131 (I-131), used as the tracer, was injected onto the surface of the soil, and was allowed to migrate with a constant head of water t
