Population Growth

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

The Concept of Multiple Allelism

Altruism

Altruism

Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.

Pleiotropy

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Excess Pressure Inside a Drop and a Bubble

Excess Pressure Inside a Drop and a Bubble

The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops.

Area of Science:

Public Health Research
Bibliometrics
Scientific Collaboration

Context:

Analysis of authorship trends in Brazilian scientific journals.
Focus on public health and medical journals indexed in SciELO and LILACS.
Inclusion of journals with Qualis (Capes) classification B-1 or higher.

Purpose:

To analyze the increasing number of authors per article in Brazilian scientific journals focusing on public health.
To evaluate the evolution of the median number of authors and the proportion of articles with more than four authors.
To estimate the association between publication triennium and the presence of multiple authors.

Summary:

A study examined articles published between 1999 and 2010 in Brazilian public health and medical journals.
Results show a consistent increase in the median number of authors and the proportion of articles with over four authors.
The odds ratio for articles with four or more authors increased significantly over successive triennia, reaching 2.39 in the last period.

Impact:

Demonstrates a clear trend towards increased author numbers in public health research publications.
Highlights the growing collaborative nature of scientific endeavors in Brazil.
Provides bibliometric data relevant for understanding research productivity and authorship practices.
