Summary
Researchers developed the PR-index, combining h-index and PageRank, to better evaluate citation impact. This new metric accounts for citation source value, offering a more balanced assessment than existing indices.
Area of Science:
- Bibliometrics
- Information Science
- Computer Science
Background:
- Traditional metrics like the h-index have limitations in assessing author and institutional impact.
- Existing indices often fail to differentiate the value or authority of citation sources.
Purpose of the Study:
- To introduce a novel impact assessment metric, the PR-index, by integrating the h-index with the PageRank algorithm.
- To address the limitations of individual indices by incorporating citation source value and authority.
- To provide a more balanced and accurate measure of scientific impact.
Main Methods:
- The PR-index is defined by modifying the h-index to use PageRank scores instead of raw citation counts.
- It evaluates citation sources based on both their popularity (PageRank score) and publication authority.
- The methodology was tested using data from Microsoft Academic Search and SIGKDD innovation award benchmarks.
Main Results:
- The PR-index demonstrated a more balanced impact measurement compared to several existing indices in extensive tests.
- Validation on Microsoft Academic Search data and SIGKDD innovation award benchmarks confirmed its efficacy.
- The PR-index showed potential predictive power for future awards based on growth dynamics.
Conclusions:
- The PR-index offers a more nuanced evaluation of scientific impact by considering citation source quality.
- Its simplicity and resemblance to the h-index facilitate its adoption in the research community.
- The PR-index represents a valuable addition to the suite of available bibliometric indicators.

01:30Impact
564
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

01:30Types of Impact
1.1K
Impacts can be classified in various forms, primarily under two subgroups: central impact and oblique impact. A central impact occurs when two objects collide head-on, possessing opposite velocities aligned along the line of impact. Conversely, an oblique impact occurs when two objects collide at an angle, resulting in a modification of both direction and velocity.

01:19Impact Loading
794
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.

01:08Outliers and Influential Points
6.6K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...

01:21Impact Strength of Concrete
678
Impact strength in concrete is a critical measure that reflects the material's capability to endure the forces applied during pile driving and when supporting machinery foundations that experience impulsive loads. It is also essential when handling precast concrete components to prevent accidental damage. The impact strength is assessed by observing the concrete's resistance to repeated impacts and energy absorption capacity. A key indicator of significant damage to concrete is when it...

01:37Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...
