Summary
This study introduces a new metric, Spatial Research Leadership Rank, to identify leading institutions in global research collaborations. It considers collaboration intensity and geographical factors, outperforming existing methods in predicting scholarly impact.
Area of Science:
- Bibliometrics and scientometrics
- Network analysis in scientific collaborations
Background:
- Global research collaborations are increasing, with leadership playing a key role.
- Existing leadership metrics lack consideration for collaboration intensity and spatial features.
Purpose of the Study:
- To develop a novel metric for research leadership that incorporates collaboration intensity and spatial features.
- To identify leading institutions in global research networks by considering geographical distance and cross-linguistic borders.
Main Methods:
- Constructed an institution-level weighted co-authorship network with edge weights for collaboration intensity and spatial score.
- Developed the Spatial Research Leadership Rank metric based on three criteria: frequency of leadership, leadership in long-distance/cross-linguistic collaborations, and the leadership status of collaborating institutions.
- Analyzed 323,146 publications in pharmaceutical sciences (2010-2018) and Information Science and Library Science.
Main Results:
- The Spatial Research Leadership Rank effectively identifies leading institutions.
- This novel metric outperforms baseline metrics in predicting the scholarly impact of institutions.
- The findings were robust across different scientific fields.
Conclusions:
- Spatial features and collaboration intensity are crucial for accurately measuring research leadership.
- The Spatial Research Leadership Rank offers a more comprehensive approach to understanding global research leadership dynamics.

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,...

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,...

In social psychology, the interplay between individuals and groups is a central concern, particularly regarding how individual actions and characteristics influence group processes and outcomes. While much research emphasizes the group's power in shaping individual behavior, it is equally significant to understand how individuals contribute to the functioning, development, and success of groups.Individual Roles in Group Productivity and Decision-MakingIndividuals are not passive participants in...

01:08Outliers and Influential Points
5.1K
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...

01:21Trait Centrality

Trait centrality refers to the degree to which a particular characteristic influences the overall impression of an individual. Some traits exert a disproportionately strong impact on perception, shaping how people interpret other attributes of a person. Solomon Asch first systematically studied this phenomenon in 1946.Asch’s Experiment on Trait CentralityAsch's seminal study demonstrated the centrality of certain traits through a controlled experiment. Participants were presented with a...

01:28Impact of Groups on Individuals

Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...
