The Scientific Method

The Scientific Method

The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Mate Choice

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Types of Selection

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...

Limits to Natural Selection

Limits to Natural Selection

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.For one, natural selection can only act upon existing genetic variation. Hypothetically, redtusks may enhance elephant survival by deterring ivory-seeking poachers. However, if there are no gene variants—or alleles—for redtusks, natural selection cannot increase the prevalence of...

Criterios de los autores para la selección de las revistas.

¹Department of Family and Preventive Medicine, Emory University School of Medicine, Atlanta, Ga. 30303-3219.

|July 13, 1994

Resumen

Los autores priorizan el prestigio de la revista, el número de lectores y la relevancia del tema para las presentaciones iniciales de manuscritos. Para las presentaciones posteriores, la probabilidad de aceptación y la adecuación al tema se vuelven más críticas para que los autores elijan dónde publicar.

Área de la Ciencia:

Educación médica y educación médica.
Publicación académica Publicación académica.
La Comunicación Científica es la Comunicación Científica.

Sus antecedentes:

Comprender los criterios de selección de revistas de los autores es crucial para la publicación académica.
Se encuestó a la facultad académica de la Escuela de Medicina de la Universidad de Stanford.

Objetivo del estudio:

Evaluar los métodos y factores que influyen en las decisiones de los autores sobre la presentación de artículos a revistas.
Identificar los criterios clave para las presentaciones de manuscritos iniciales y posteriores.

Principales métodos:

Se distribuyó una encuesta de 1992 a 479 profesores clínicos y de investigación activos.
Se logró una tasa de respuesta del 63,7% (305 profesores).
Los encuestados clasificaron los factores en una escala de 1 (poco importante) a 6 (muy importante).

Principales resultados:

Para las presentaciones iniciales, el prestigio de la revista (5.2), el número de lectores (4.8) y la relevancia del tema (4.8) fueron primordiales.
La probabilidad de aceptación (4.4) y el tamaño de la circulación (4.1) también fueron significativos.
Para las presentaciones posteriores, la probabilidad de aceptación (5.0) y la relevancia del tema (4.7) se volvieron más importantes.

Conclusiones:

El prestigio de la revista, la alineación de temas y el número de lectores son claves para las colocaciones iniciales de manuscritos.
Los factores pragmáticos como las tasas de aceptación ganan importancia para las presentaciones repetidas.
Las ideas pueden guiar a los editores para mejorar el atractivo de la revista para los autores.
