Departmental h-Index: Evidence for Publishing Less?
Pascal N Tyrrell1, Alan R Moody1, J Oscar C Moody1
1Department of Medical Imaging, University of Toronto, Toronto, Ontario, Canada.
Summary
The combined h-index for a medical imaging department grew significantly from 2000-2014. Fostering impactful research within faculty is key to increasing a department's h-index.
Area of Science:
- Medical Imaging
- Bibliometrics
- Academic Research Evaluation
Background:
- The h-index is a widely used metric to assess the impact of individual researchers.
- Evaluating the collective research impact of academic departments is crucial for institutional assessment.
- Tracking departmental h-index trends provides insights into research productivity and influence over time.
Purpose of the Study:
- To measure and describe the evolution of the combined h-index for a large university medical imaging department.
- To analyze factors influencing the change in departmental h-index over a 14-year period.
Main Methods:
- Faculty data from the University of Toronto's Department of Medical Imaging were collected for six years between 2000 and 2014.
- Individual and departmental h-indices were calculated using Scopus citation data.
- Linear regression analysis was employed to identify factors contributing to changes in the departmental h-index.
Main Results:
- The number of faculty members increased from 117 to 186, and the departmental h-index rose from 48 to 142 between 2000 and 2014.
- The median faculty h-index increased from 4 to 10 during the study period.
- Each additional staff member correlated with a 1.4 increase in the departmental h-index, while a one-point increase in median faculty h-index boosted the departmental h-index by 15.7.
Conclusions:
- Fostering impactful research among faculty members is essential for enhancing a department's h-index.
- The h-index serves as a valuable metric for evaluating academic radiology departments internally and comparatively.
- Longitudinal tracking of departmental h-index can inform strategies for research development and impact assessment.

44.6K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

01:01Production Efficiency
19.0K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

01:32The Scientific Method
274.2K
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

01:16Statistical Inference Techniques in Hypothesis Testing: Parametric Versus Nonparametric Data
565
Statistical inference techniques, paramount in hypothesis testing, differentiate into two broad categories: parametric and nonparametric statistics.
Parametric statistics, as the name suggests, assumes that data follow a specific distribution, often a normal distribution. This assumption enables robust hypothesis testing and estimation. Parametric methods, like the Student's t-test or Goodness-of-fit test, are frequently employed in biostatistics due to their robustness. For instance,...

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
