On the relation between gene flow theory and genetic gain

open access: yesGenetics Selection Evolution, 2000
In conventional gene flow theory the rate of genetic gain is calculated as the summed products of genetic selection differential and asymptotic proportion of genes deriving from sex-age groups.

The Effect of Redistributive Policies on Saving and Capital Accumulation: An Overlapping Generations Approach [PDF]

open access: yesFaslnāmah-i Pizhūhish/Nāmah-i Iqtisādī, 2018
Justice is known as one of the most important principles of any economic system and pursuing other objectives such as efficiency and economic growth should go along with achieving justice. In Islamic economics, redistributive justice as a kind of justice

Evolving Populations with Overlapping Generations

open access: yesTheoretical Population Biology, 2000
In this paper, we extend a previously published model of an evolving finite population of multi-locus organisms, where the dynamics of the evolving system are described by the cumulants of the population efficacy distribution. We consider the case of overlapping generations and compare it to the previously studied case where generations are discrete ...

Optimal mass selection policies for schemes with overlapping generations and restricted inbreeding

open access: yesGenetics Selection Evolution, 2000
Optimum breeding schemes for maximising the rate of genetic progress with a restriction on the rate of inbreeding (per year or per generation) are investigated for populations with overlapping generations undergoing mass selection.

Intertemporally separable, overlapping-generations economies [PDF]

open access: yesJournal of Economic Theory, 1984
Intertemporally separable, overlapping-generations economies typically have a sequentially finite number of equilibria, though the equilibrium set may, even with probability 1, be uncountable.

General Complex-Valued Overlap Functions

open access: yesJournal of Mathematics, 2021
Overlap function is a special type of aggregation function which measures the degree of overlapping between different classes. Recently, complex fuzzy sets have been successfully applied in many applications. In this paper, we extend the concept of overlap functions to the complex-valued setting.

Population Consequences of Parent-Offspring Competition: An Individual-Based Model

open access: yesStudia Ecologiae et Bioethicae
The article compares different versions of individual-based models of single population dynamics with overlapping generations with results of the model of population with non-overlapping generations. In all models, various versions of global competition

BIOMETRIC CHARACTERISTICS OF THE LARVAL STAGES AND POPULATION DYNAMIC OF THE INVASIVE TOMATO LEAFMINER TUTA ABSOLUTA (MEYRICK, 1917) IN GREENHOUSE

open access: yesNatural Resources and Sustainable Development, 2023
The South American tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), invaded Algeria in 2008 and caused severely significant devastation to tomato plants.

Adult Learning, Economic Growth and the Distribution of Income

open access: yesEconomies, 2018
Technological change causes three consequences: it guarantees economic growth, it requires employees to acquire more skills and human capital, and it increases inequality if employees are not capable adapting to new technologies.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
