Summary
This study analyzes European Union funded research projects from 2007-2020 using network analysis and curve fitting. It reveals patterns in research collaborations and institutional activity over time.
Area of Science:
- Bibliometrics and Scientometrics
- Network Science
- Public Policy Analysis
Background:
- Analyzing funded research projects is crucial for evaluating scientific output and impact.
- The European Union's research programs, including the 7th Framework Programme (FP7) and Horizon 2020 (H2020), represent significant investments in scientific advancement.
Purpose of the Study:
- To analyze the collaborative networks of scientific institutions funded by the European Union between 2007 and 2020.
- To identify temporal trends and patterns in European research activities and institutional collaborations.
Main Methods:
- Construction of yearly complex networks based on co-funded research projects.
- Computation of nodal centrality measures to quantify institutional importance.
- Application of rank-size procedures with parametric curve fitting to analyze network data.
- Clustering based on fitted curves to identify regularities and deviations in research patterns.
Main Results:
- Identification of distinct patterns in scientific collaboration networks over the 2007-2020 period.
- Quantification of institutional roles and influence within EU-funded research.
- Detection of temporal regularities and deviations in research funding and collaboration.
Conclusions:
- The study provides a comprehensive view of European research activity and collaboration dynamics.
- Network analysis combined with curve fitting offers a robust methodology for evaluating large-scale research programs.
- Findings offer insights for future research funding strategies and policy-making in the EU.

Unlike parametric methods, nonparametric statistics are ideal for nominal and ordinal data, requiring fewer assumptions about the population's nature or distribution. This makes nonparametric methods easier to apply and interpret, as they do not depend on parameters like mean or standard deviation. One common approach in nonparametric analysis is to sort data according to a specific criterion. For instance, we might arrange weather data from hottest to coldest days in a month or rank cities...

01:20Cluster Sampling Method
12.0K
Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Friedman's Two-Way Analysis of Variance by Ranks is a nonparametric test designed to identify differences across multiple test attempts when traditional assumptions of normality and equal variances do not apply. Unlike conventional ANOVA, which requires normally distributed data with equal variances, Friedman's test is ideal for ordinal or non-normally distributed data, making it particularly useful for analyzing dependent samples, such as matched subjects over time or repeated measures...

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

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,...
