Attribution Theory

Attribution Theory

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

Social Exchange Theory

Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Band Theory

Band Theory

When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

The Atomic Theory of Matter

The Atomic Theory of Matter

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Summary

Ecologists perceive limited interaction between theoretical and empirical research. Citation network analysis reveals stronger integration than expected, suggesting avenues for further connection in ecology and evolutionary biology.

Area of Science:

Ecology
Evolutionary Biology

Background:

Ecologists and evolutionary biologists believe theoretical and empirical research should be integrated.
However, they perceive minimal actual interaction between these domains.

Purpose of the Study:

To evaluate the perceived disconnect between theoretical and empirical research in ecology and evolutionary biology.
To quantify the interaction between these research domains using citation network analysis.

Main Methods:

Citation network analysis of literature on sexual selection and speciation.
Analysis of cross-citations between theoretical and empirical research papers.
Cocitation network analysis.

Main Results:

54%-60% of citations are within a paper's own category (theoretical or empirical).
17%-23% of citations are across categories, focusing on highly cited papers.
Positive correlation observed between within-category and cross-category citations.

Conclusions:

Theoretical and empirical research in ecology and evolutionary biology are more integrated than commonly perceived.
Review articles act as key integrators between theoretical and empirical literature.
Further integration can be achieved by recognizing theoretical models as analogous to empirical systems.
