Summary
Research paper retractions are increasing. In Computer Science (CS), 8% of retracted papers lack clear reasons, and retracted studies continue to be cited, impacting reviews.
Area of Science:
- Computer Science research integrity
- Scholarly publishing ethics
Background:
- Research paper retractions are a growing concern.
- Information on retracted papers is publicly available but fragmented and inconsistent across publishers.
Purpose of the Study:
- To assess the extent and nature of retractions in Computer Science (CS).
- To analyze post-retraction citation behavior of retracted works.
- To evaluate the impact of retractions on systematic reviews and mapping studies.
Main Methods:
- Analysis of the Retraction Watch database.
- Extraction of citation data from Web of Science and Google Scholar.
Main Results:
- Approximately 8% of 33,955 retracted papers are in CS (2,816).
- 56% of CS retracted papers lack clear reasons for retraction, compared to 26% in other fields.
- Retracted CS papers are cited after retraction (median 3 times) and impact systematic reviews (approx. 30% cited).
Conclusions:
- Retractions are common, necessitating community attention and standardized procedures.
- Caution is advised for secondary analyses and meta-analyses due to potential contamination from retracted primary studies.

16.0K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

01:12Retrieval
144
Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

Regression analysis is a statistical tool that describes a mathematical relationship between a dependent variable and one or more independent variables.
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:

01:29Protein Folding Quality Check in the RER
3.8K
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

R is a powerful software environment for statistical computing and graphics. Originating as an implementation of the S language, developed at Bell Laboratories, R has evolved into a robust, open-source statistical software favored by statisticians and data scientists worldwide. Its comprehensive suite includes data manipulation, calculation, and graphical display capabilities, making it versatile for data analysis and visualization. Its programming language is at the core of R's...

01:11Statistical Analysis: Overview

When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...
