Founder effectiveness in leveraging entrepreneurial orientation
Management Decision, 2012PurposeThis paper aims to explore the effects of entrepreneurial orientation (EO) on firm survival and examine whether founder chief executive officers (CEOs) are more effective than other types of managers at utilizing entrepreneurial orientation at initial public offerings (IPOs).Design/methodology/approachUsing survival analysis the authors ...

Early Founders and the Founder Effect
2019This chapter discusses key social, geographic, and chronological patterns of early English development in New England, including the early European settlement patterns and how they have led to long-term sociolinguistic patterns in the region (the Founder Effect).

The origin of species (speciation)—the process by which two or more species evolve from a single ancestral species—is a central problem in evolutionary biology. During the evolutionary synthesis of the twentieth century, the dominant theory of speciation for those working on sexually reproducing animals was allopatric speciation.

Founder effects in modern populations
Science, 2018Human Evolution The genomes of ancient humans can reveal patterns of early human migration (see the Perspective by Achilli et al. ). Iceland has a genetically distinct population, despite relatively recent settlement (∼1100 years ago). Ebenesersdottir et al.

Founder effect and genetic disease in Sottunga, Finland
American Journal of Physical Anthropology, 1988AbstractPedigree data are analyzed in order to determine the factors responsible for the high frequencies of certain genetic disorders in an isolated Swedish‐speaking population of Finland's Å land archipelago. The founders of Sottunga are identified, and the genetic contributions of each founder to descending birth cohorts are estimated. Founders born

Founder effect: assessment of variation in genetic contributions among founders.
Human biology, 1994We present a Monte Carlo method for determining the distribution of founders' genetic contributions to descendant cohorts. The simulation of genes through known pedigrees generates the probability distributions of contributed genes in recent cohorts of descendants, their means, and their variances. Genealogical data from three populations are analyzed:

Population Bottlenecks and Founder Effects
2006Abstract Patterns of geographic variation arise from the combined effects of migration, selection, mutation, and genetic drift. One measure of the evolutionary potential for such geographic differentiation is the level of additive genetic variance (i.e., the linear resemblance between relatives, hereafter denoted VA; see Roff, Ch.

The founder effect and genetic disease of cattle
New Zealand Veterinary Journal, 1977Abstract Extract The derivation of large populations of beef cattle from a smallgenetic pool has been a feature of the cattle industry in this country from the earliest days of settlement. In recent years the importation of small numbers of exotic beef cattle and the rapiddissemination of this genetic material, aided by artificial breeding techniques ...
