This paper describes a fictional questionnaire intended to be completed by applicants to an intentional community devoted to gamifying all aspects of its members’ lives. This format was chosen as a plausible alternative to science fiction tropes that include the population of entire worlds or counties. It was also chosen because the historical motivations for creating intentional communities cl...

Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations and lack a unifying framework. Here, we propose a unified network-based framework sufficiently novel in its flexibility to capture a wide varie...

We study the responses of discretely reproducing populations to periodic fluctuations in three parameters, the carrying capacity and two demographic characteristics of the species (three parameters). We prove that small 2-periodic fluctuations of the three parameters generate 2-cyclic oscillations of the population. We develop a signature function for predicting the responses of populations to ...

This work presents a discrete time model for the dynamics of a size-classified benthic population with planktonic larvae. Recruitment, decoupled from local reproduction by larval dispersal, is represented in the model as an external subsidy to the local population. Analysis of the model reveals the importance of recruitment and growth plasticity in determining the stability of an equilibrium wh...

The first positive trend is the slowing of global population growth. There is a significant shift in global fertility that will enable us at least to think about moving to a world of near stable populations within a century, maybe sooner. Fertility in about 40 per cent of the world’s countries is now below the replacement rate. Another 40 per cent are experiencing continued downward movement of...

This paper presents a discussion of coordination properties within populations of geospatially distributed embodied agents. We define two axes: interaction mechanisms and population diversity; and we present a new framework designed for exploring the relationship between values along these axes and the efficiency of solutions for a set of related tasks, e.g., foraging, resource allocation and a...

The majority of the world's population will live in cities in the next few years and the pace of urbanization worldwide will continue to accelerate over the coming decades. While the number of megacities is projected to increase, the largest population growth is expected to be in cities of less than one million people. Such a dramatic demographic shift can be expected to have an impact on popul...

In this paper a mathematical model was developed to study the dynamics of visceral leishmaniasis (VL) the in Sudan. To develop this model, the dynamics of the disease between three different populations, human, reservoir and vector populations was considered. The model analysis is done and the equilibrium points are analyzed to establish their stability. The threshold of the disease, the basic ...

Evolutionary game theory is an increasingly important way to model the evolution of biological populations. Many early models were in the form of matrix games, or bimatrix games in asymmetric situations when individuals occupy distinct roles within the contest, where rewards are accrued through independent contests against random members of the population. More recent models have not had the si...

Regional dimensions and trends in population aging: Russia/Eastern Europe Population aging is a global phenomenon and countries of Eastern European also experience rapid increase in the proportion of older people. The proportion of elderly people in the Eastern Europe is currently lower than in the European region as a whole. However this population aging is expected to continue over the next f...
