背景情况:
- 期刊声望指标,如Scimago期刊排名 (SJR),对于评估科学影响至关重要.
- 了解这些指标的时间动态对于跟踪科学趋势和影响至关重要.
研究的目的:
- 调查21年来期刊声望指标的排名相关系数的时间演变.
- 将这些动态与最富有的个人之间的财富相关性进行比较.
- 分析期刊声望演变中的学科特定趋势.
主要方法:
- 通过使用21年的Scimago Journal Rank数据,对各种学科的9856个期刊的排名相关系数 (肯德尔的tau) 的分析.
- 与财富相关性数据进行比较.
- 基于经济系统模型的Scimago Journal Rank概率分布函数的蒙特卡洛模拟.
- 检查跨学科的重叠比率.
主要成果:
- 与人类财富相关性相比,期刊声望等级相关性表现出质量上的相似性,但在数量上变化较弱.
- "农业和生物科学"和"地球和行星科学"显示了排名相关性最典型的时间演变.
- 肯德尔等级相关系数和重叠比率通常随着时间的推移线性下降,初始衰减更快.
- 在Scimago Journal & Country Rank和Web of Science数据之间存在差异,这是由于期刊的覆盖范围不同.

Measures of Central Tendency
16.0K
The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

Ratio Level of Measurement
17.8K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated....

Confidence Coefficient
7.6K
The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under...

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

Nominal Level of Measurement

The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. Not every statistical operation can be used with every set of data. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
The data that cannot be measured but can be grouped into categories fall under the nominal level of measurement. Data that is measured using a nominal...

The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks...
