D1 sql, run 5: the query session

## The data

You can't see the data, but you can query it. It is in DuckDB, in the tables below. Write DuckDB SQL.

To run queries, reply with one or more fenced blocks (```sql), and nothing else is needed:
each is run and its results sent back to you. You have up to 8 rounds of queries.
When you have what you need, reply with the final answers and no queries.

All columns are text (VARCHAR); dates are ISO strings.

- `institutions` (18 rows): institution_id, name, ror, country, type, parent_id
- `authors` (38 rows): author_id, name, orcid
- `sources` (8 rows): source_id, name, issn, type, tier
- `works` (85 rows): work_id, title, year, type, source_id, doi, version_of, is_retracted, record_source
- `authorships` (138 rows): work_id, author_id, author_position, institution_id, affil_seq
- `citations` (71 rows): citing_work_id, cited_work_id

## Questions

Answer each question below from the data above. Start each answer on a new line with its
number in bold, like **Q1.**, give the direct answer first, then at most two sentences of
reasoning that cite the records (IDs) you relied on.

Then end with one JSON block (```json) holding the structured answer to each question listed
here, with exactly these fields, shaped like {"Q1": {"field": value}, ...}. Name works, authors, institutions and sources by their record ID: the work_id, author_id, institution_id or source_id in the CSV files, or the part of the IRI after res: in the RDF (W01, A07, I02, S03; not their titles or names).

**Q1.** 1. A01, A02 and A03 share ORCID 0000-0002-9841-6229.
**Q2.** W01, W02, W03, W04, W05, W06, W07, W12, W19. This takes Mara Ellison as the one person behind A01, A02 and A03 (same ORCID); A01 alone is on W01, W04, W05, W06 and W12.
**Q3.** No. W37 is by A05 and W38 by A06, and their ORCIDs differ.
**Q4.** 2 (W14 and W37). A05 also has no other works.
**Q5.** No. W08 is by A04 and W01 by A01; their ORCIDs differ.
**Q6.** A01, the Mara Ellison person, with 6 works (W01, W02/W03 counted once, W06, W07, W12, W19). A07 and A08 have 4 each.
**Q7.** 6. W02 is a preprint of W03, so the pair counts once.
**Q8.** I01 (I04 → I03 → I02 → I01).
**Q9.** 12: W01, W02/W03, W06, W07, W12, W13, W19, W70, W71, W72, W73, W74.
**Q10.** 16. This is the 12 above plus W14, W28, W29 and W37 through I05.
**Q11.** 9: W08, W16, W20, W21, W22, W23, W90, W91, W92. I counted retracted W23 and the STG-sourced W90–W92 as research works, since the data does not exclude them.
**Q12.** Full 3 (W20, W21, W22). Fractional 2.0 (0.5 + 0.5 + 1).
**Q13.** Full: I09 (4 works against 3). Fractional: I07 (2.0 against 1.0).
**Q14.** Full 7 (W06, W12, W13, W28, W29, W71, W72). Fractional 6.0, because W28 and W29 each contribute 0.5 and the rest 1.
**Q15.** 4 (W12, W21, W28, W51). W05 is an erratum and W10 is front matter, so both are excluded.
**Q16.** 11: W01, W08, W13, W20, W29, W31, W32, W52, W71, W74, W91. W04 and W09 are excluded by type.
**Q17.** W04 (editorial) and W05 (erratum).
**Q18.** 4: W01, W02/W03, W13, W72. W05 is an erratum.
**Q19.** 7: W12, W13, W14, W15, W16, W17, W18. W15 cites both versions and is counted once.
**Q20.** W02 (of W03) and W42 (of W31).
**Q21.** 4: W27, W31/W42, W39, W50.
**Q22.** More in total: W30 (5 against 4). More in window: W31 (4 against 1).
**Q23.** Total 5 (W60–W64). In window 1 (W60, 2020).
**Q24.** 4 (W20, W21, W22, W23).
**Q25.** 10 (W20: 3, W21: 2, W22: 4, W23: 1).
**Q26.** Yes. W23 is flagged retracted but is still an article, and nothing in the data excludes it.
**Q27.** I12 (Université de Lorvain), with 3 citing works (W33, W34, W35). W90–W92 are Kesting's own works, so they are excluded.
**Q28.** 1 (W32).
**Q29.** Author 2 (W12 and W13), institution 2 (W12 and W13), country 4 (W12, W13, W14, W15, all GB).
**Q30.** 3 (W12, W13, W14).
**Q31.** W50, W51, W52, W90. These cite W40 or W41, which are the works citing W01.
**Q32.** 6: W40, W41, W50, W51, W52, W90.
**Q33.** W22, with 4 citations (W34, W90, W91, W92).
**Q34.** 5 (W08, W16, W90, W91, W92).
**Q35.** 1 (W21). W24 is a supplement type and is excluded.
**Q36.** 0. W17 and W24 are supplements and W76 is an editorial.
**Q37.** I04 (listed first), though W70 also lists I06 as a second affiliation.
**Q38.** I06, I04, I03, I02, I01.
**Q39.** 4 (W01, W13, W71, W74), all in S01. This assumes K3 is the highest tier.
**Q40.** S01 (K3). The data does not document the tier ordering, so this assumes a higher number means a higher tier.
**Q41.** No, under the same assumption: S03 is K1 and S02 is K2.
**Q42.** 2 (W07, W75).
**Q43.** Yes. W07 is an article.
**Q44.** I02, I03, I04, I05, I06.
**Q45.** 4 (W70, W71, W73, W74).
**Q46.** I01 (I06 → I02 → I01).
**Q47.** Under full counting, Rostval has 4 works in 2024 (W21, W27, W28, W29) against Kesting's 3. Each Rostval work is shared across four authors from different institutions, so it gets only 0.25 each, 1.0 in total. Kesting's W22 is single-author and W20 and W21 split its credit less, giving 2.0.
**Q48.** The premise doesn't hold. W70 is credited to I04 and I06, both under I02, so it counts as a University of Albury work and is included in Q9.
