Genetic Dissection of Transcriptional Regulation in Budding Yeast

To begin to understand the genetic architecture of natural variation in gene expression, we carried out genetic linkage analysis of genomewide expression patterns in a cross bet...

Structure and Function of Stream Ecosystems

General functional, interrelated components have been defined and initially dimensioned for representative stream ecosystems. Additional or alternative functional criteria are s...

Prediction of Employment Status Choice Intentions

The present research applied the theory of planned behavior to predict employment status choice, defined as the intention to enter an occupation as a wage or salaried individual...

How Big Is the Random Walk in GNP?

This paper presents a measure of the persistence of fluctuations in gross national product (GNP) based on the variance of its long differences. That measure finds little long-te...

Can You See the Real Me? Activation and Expression of the “True Self” on the Internet

Those who feel better able to express their “true selves” in Internet rather than face‐to‐face interaction settings are more likely to form close relationships with people met o...

Alternative factor specifications, security characteristics, and the cross-section of expected stock returns1We are especially grateful to Eugene Fama (a referee), an anonymous referee and Bill Schwert (the editor) for insightful and constructive suggestions.

HOGWILD!: A Lock-Free Approach to Parallelizing Stochastic Gradient Descent

Stochastic Gradient Descent (SGD) is a popular algorithm that can achieve state-of-the-art performance on a variety of machine learning tasks. Several researchers have recently ...

Nested clade analyses of phylogeographic data: testing hypotheses about gene flow and population history

Since the 1920s, population geneticists have had measures that describe how genetic variation is distributed spatially within a species’ geographical range. Modern genetic surve...

Positive Natural Selection in the Human Lineage

Positive natural selection is the force that drives the increase in prevalence of advantageous traits, and it has played a central role in our development as a species. Until re...

Separating population structure from population history: a cladistic analysis of the geographical distribution of mitochondrial DNA haplotypes in the tiger salamander, Ambystoma tigrinum.

Abstract Nonrandom associations of alleles or haplotypes with geographical location can arise from restricted gene flow, historical events (fragmentation, range expansion, colon...

Phylogeographic studies in plants: problems and prospects

Genetic structuring of plant populations is strongly influenced by both common ancestry and current patterns of interpopulation genetic exchange. The interaction of these two fo...
