Abstract
Dyer, Hadley. Potatoes on Rooftops: Farming in the City. Toronto: Annick Press, 2012. Print. With the increased public interest in urban agriculture, this is a timely book. While the publishers present it as being for grades 4-7, the content and reading level is much higher, scoring at the Tenth Grade on the Coleman-Liau Index and 9.2 on the Flesch-Kincaid Grade Level test. The design looks like a children’s book, with backgrounds composed of bright colour blocks, small monochrome drawings and many irregularly shaped photographs with overlapping captions that look as if they are hand-printed. The text is often informal, using contractions and questions to engage the reader. “What’s a city dweller to do if she doesn’t want to pay a king’s ransom for an egg?” (p. 18). However, the content is dense and covers urban agriculture almost like a text book. It begins with a substantial introductory section on the state of food and the need for urban agriculture then moves through examples of small scale urban agriculture, larger scale urban agriculture and ends up with some of the larger social and political movements and philosophies. There is also a glossary, resource list and index. While the author is from Toronto and this book received Ontario Arts Council Funding, there is little Canadian content. While the author does cite a number of international examples including some from Africa, Japan and Scotland, it is clear that the market for this book is the United States. There are a few Toronto projects mentioned and the Inuvik Community Greenhouse, which is an old arena, but there is little said about the practicalities of urban gardening in Canada. Climate is a major factor in successful gardening anywhere and the growing conditions of most American locations are quite different from those in most of Canada. It is a lot easier to be an urban gardener in Florida than it is in Edmonton. This book is a good introduction to the concepts of urban gardening but will be most useful to teen and adult readers. Recommended for high school and public libraries. Recommendation: 3 stars out of 4Reviewer: Sandy CampbellSandy is a Health Sciences Librarian at the University of Alberta, who has written hundreds of book reviews across many disciplines.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
