A BIBLIOMETRIC ANALYSIS OF SINGLE MOTHERS
Bibliographic record
Abstract
In recent years, there has been an increasing amount of research on single mothers internationally. This article analyzes 1543 research papers on single mothers from Web of Science database using CiteSpace literature analysis software. The study found that research on single mothers covers 79 countries globally, forming a close and comprehensive cooperative network between them. The North American region, including the United States and Canada, is a core research force in the field of single mothers. The top 15 research institutions produced more than 30 papers each, with the University of California System ranking first with a total of 72 papers. The journal with the most publications was the Journal of Marriage and Family, with a total of 44 papers. There were 8 authors who published more than 10 papers, with Herbst CM having the most with 16 papers. The frequency of citations for research on single mothers has shown a significant increasing trend in recent years, with a total of 36,624 citations, an average of 23.74 citations per paper, and an h-index of 83. Through the analysis of clustering networks and high-frequency keywords, the research hotspot on single mothers mainly focuses on four aspects: the psychological health of single mothers, the economic and employment status of single mothers, the children of single mothers, and the social support of single mothers.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
