Poster

Towards a Disposal Criterion for the Battery Drawer

Ronja Oyelaran, Iben Chikere, Verity Marris · August 2026 · doi:10.5555/slop.dnd4b9

A research poster from the School of Emergent Priorities recovers 2,400 loose cells from 180 household drawers, measures the residual capacity of each under constant-current discharge, and costs four disposal strategies --- discard on sight, the drop test, a bench tester, and retaining everything --- as a full economic evaluation expressed in dollars per 1,000 usable cell-hours retained. Retain-all is not dominated: the drop test recovers 61 per cent of the cell-hours the bench tester recovers at 6 per cent of its time cost, and test-then-discard clears the adopted threshold only where the household hour is valued below $22.50. The poster reads the drawer as a defensible allocation rather than a lapse in diligence, and records the $840 per 1,000 cell-hours figure as the threshold against which proposals for a tested-cell station are now assessed.

Twenty Cells Certify a Thousand Punnets

Osei Vandermeer, Joost Nwosu, Solveig Adeyemi · August 2026 · doi:10.5555/slop.nueyan

A research poster from the School of Continuous Improvement specifies a single-sampling attributes plan for the seedling punnets a garden-centre chain receives, drawing twenty cells from each incoming lot and accepting on one failure to germinate. Across 316 lots over fourteen months the plan discriminates as designed, at a producer's risk of 3.6 per cent and a consumer's risk of 10 per cent at eighteen per cent nonconforming, but returns its verdict a median of twenty-one days after receipt against a median shelf residence of eight, so 91.5 per cent of lots are certified after the last punnet has been sold.

At What Tilt Does a Hung Frame Read as Crooked?

Casimir Beng, Torun Ezeigwe, Marit Osayande · August 2026 · doi:10.5555/slop.qz0v94

A research poster from the School of Continuous Improvement shows 312 observers the same framed print at eleven tilt levels across four frame widths, fitting a psychometric function per observer to locate the point at which a hung frame reads as crooked. The median 75 per cent detection threshold is 0.74 degrees at 600 millimetre frame width and falls to 0.60 degrees at 900 millimetres, leaving every width band above the 0.40 degree levelling tolerance that the estate's revised hanging schedule now requires each framed work to be attested against quarterly.

Measuring the Bags Changed How Often They Came Back

Lindiwe Achterberg, Ingeborg Nwachukwu, Runa Adegoke · August 2026 · doi:10.5555/slop.b51mo6

A research poster from the School of Emergent Priorities runs a four-phase withdrawal series across 24 households and 18 weeks, testing whether a laminated card at the internal door returns reusable shopping bags to the car boot within 24 hours of unpacking. Return rates rise from a 34.1 per cent baseline to 71.4 per cent under the prompt and settle at 63.4 per cent once the card is removed, with only 2 of 24 households recovering their own baseline; the residual is attributed to the twice-daily log, since adopted by the Adaptive Metrics Lab as its standard household protocol.

Strategic plan

Who Else Was in the Room?

Ronja Oyelaran, Iben Chikere · August 2026 · doi:10.5555/slop.vdhi9g

Slop University's Strategic Plan 2026-2031 rebuilds the University's integrity settings around one public register of declared connections, and removes the materiality test at lodgement so that a connection is declarable because it exists rather than because the person holding it judged it significant. The plan's binding provision runs the other way from sector practice: a declared connection is noted and the business proceeds, with required withdrawal retired from the delegations framework and a nil return referred for review.

Strategic plan

Every Unit Will Be Issued a Risk Allowance

Solveig Adeyemi, Bram Ntuli · August 2026 · doi:10.5555/slop.ryazwo

Slop University's Strategic Plan 2026-2031 adopts the exposure-hour as an institutional unit of account and provisions each organisational unit an annual Exposure Allowance against it, metered where exposure is actually taken --- the store-room ladder, the bench at a community shed, the urn in a tea room --- rather than estimated afterwards from a report. The plan's binding provision is a symmetry in reporting: an allowance left materially undrawn at acquittal becomes a variance, considered on the same footing as one drawn too far.

Free To Call. Counted As Unused.

Fenna Okoro · August 2026 · doi:10.5555/slop.yu1oqt

A marketing poster for the School of Emergent Priorities sets the School's standing on the Horizon Register against a public telephone at the quiet end of a suburban shopping strip, where a universal-service obligation is discharged in phones retained and the demand for retaining one is read from what its coin box yields. The calls were made free, the yield has been nil on every collection round since, and the panel runs in matched light and dark cuts for the display rotation.

Swept Around. Counted Whole.

Ingrid Vasseur · August 2026 · doi:10.5555/slop.b1f5t0

A marketing poster for the School of Emergent Priorities advertises a public session of the Futures in Committee seminar series against a suburban street at first light, where a sweeper's side brush swings out to pass a parked car and the kerb kilometre it is working is recorded whole either way. Developed for the University's landscape display panels and the bus-stop rotation in matched daylight and evening versions.

Paper

Fault-Tree Decomposition and Per-Mode Weibull Hazards for a Coin-Operated Pool Table

Thandiwe Solberg, Joost Nwosu, Ingeborg Nwachukwu · August 2026 · doi:10.5555/slop.v12p0c

A paper from the School of Continuous Improvement resolves an eleven-event fault tree for the coin-operated pool table, fitting per-mode Weibull hazards to eighteen months of instrumented observation across 62 tables at 41 venues, with 44,318 logged coin insertions and 1,207 structured inspections. Top-event unavailability stands at 0.084, four accessory modes carry 0.76 of total Fussell-Vesely importance, and chalk absence alone returns a decreasing hazard of shape 0.71 against a scale of 6.4 days. The operator retained its uniform fortnightly round, adopted a game-readiness figure on its quarterly venue scorecard, and moved accessory restock to a work order.

Paper

Someone Wrote a Number Down

Torun Ezeigwe, Dagny Okafor, Lindiwe Achterberg · August 2026 · doi:10.5555/slop.munqx5

A paper from the School of Continuous Improvement assesses whether the emergency-contact field on a junior sport registration measures anything about contactability, using three seasons of records across 186 affiliated clubs (38,417 registrations) and the state association's own annual verification round. Completion reached 96.8% of registrations while 23.7% of 2,412 verified fields resolved to a reachable adult who confirmed the nomination, the largest single outcome being a duplicate of the lodging adult's own number. Agreement between indicator and criterion was negligible (Cohen's kappa = 0.01), and the 41 clubs operating a mandatory-field rule reported complete fields with contactability unchanged.

Paper

Everyone Already Has the Code

Thandiwe Solberg, Sten Okwuosa, Ingeborg Nwachukwu · August 2026 · doi:10.5555/slop.64irsz

A paper from the School of Continuous Improvement interviews the 38 cleaners, maintenance contractors and property managers who open the front-gate lockboxes at 41 short-stay properties under one letting franchise's access-assurance standard. No participant states the between-guest code rotation requirement unprompted and recognition of the standard's four remaining provisions stays below half once the clauses are read aloud, while every participant can produce a current code from at least one location outside the system of record; 27 describe the digits themselves as recording which office last held the listing.

Paper

Witnessed, and Otherwise Unchanged

Ingrid Vasseur, Petra Umbile, Marek Solheim, Kwame Lindqvist · August 2026 · doi:10.5555/slop.zjm0s2

A paper from the School of Emergent Priorities follows the six classes of statutory declaration handled by one state administrative agency across 72 months and 1.34 million lodgements, one of which moved to an unwitnessed online lodgement in month 37 while the other five retained the witnessing requirement as concurrent controls. The estimated level change in materially incorrect declarations subsequently identified is 0.14 per 10,000 (95% CI -0.61 to 0.89) and the slope change -0.004 per month, with equivalence supported against a pre-specified margin of 1.0 per 10,000 and eleven alternative specifications spanning 0.24. Over the same window documents witnessed per staffed session at nine signing stations fell 40.7 per cent with the roster unchanged, and the honorary Justice of the Peace scheme's next annual return recorded that fall as unmet demand for accessible witnessing capacity.
