Summary
Citation inequality is rising in science, with elite scientists accumulating more citations and publications. This trend coincides with increased collaboration, particularly benefiting top researchers.
Area of Science:
- Scientific publishing trends
- Bibliometrics
- Research evaluation
Background:
- Citations are crucial for scientific status and success.
- Understanding citation concentration is key to evaluating research impact.
Purpose of the Study:
- To quantify trends in cumulative citation inequality and concentration at the author level.
- To analyze the relationship between collaboration, publication rates, and citation impact.
Main Methods:
- Analysis of a linked dataset of over 4 million authors and 26 million scientific papers.
- Examination of trends across 118 scientific disciplines over 15 years.
Main Results:
- Citation inequality and concentration are increasing across natural, medical, and agricultural sciences.
- The top 1% of cited scientists are increasing their share of publications and citations.
- Increased collaboration benefits elite scientists more than ordinary researchers.
Conclusions:
- Widening author-level disparities in science are evident.
- Elite scientists are consolidating their influence, often based in top-tier universities.
- International competition and collaboration patterns are reshaping scientific success.

01:22Bias
6.6K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

18.7K
The central limit theorem, abbreviated as clt, is one of the most powerful and useful ideas in all of statistics. The central limit theorem for sample means says that if you repeatedly draw samples of a given size and calculate their means, and create a histogram of those means, then the resulting histogram will tend to have an approximate normal bell shape. In other words, as sample sizes increase, the distribution of means follows the normal distribution more closely.

Gain and phase shift are properties of linear circuits that describe the effect a circuit has on a sinusoidal input voltage or current. The circuit's behavior that contains reactive elements will depend on the frequency of the input sinusoid. As a result, it is observed that the gain and phase shift will all be frequency functions.
Gain:
Suppose Vin is the input and Vout is the output signal to a circuit.

00:52Pareto Chart
7.4K
A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.

01:14Fundamental Attribution Error
13.4K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

01:08Median
25.9K
Besides mean, the median is a widely used measure of central tendency. Typically, median is defined as the central or middle value of a data set, measured by arranging the data elements in an increasing or decreasing order. Since this middle value is not affected by the precise numerical values of the outliers or fluctuations, it is insensitive to them. Hence, in cases where a data set may have outliers or the extreme values are not known, the median is a better measure of the central tendency...
