- PaperA Feature-Integration Theory of AttentionAnne Treisman & Garry Gelade, 1980· Free
Basic visual features such as colour and orientation are registered in parallel and pre-attentively, but combining them into one perceived object requires focused attention, which is why divided attention produces illusory conjunctions.
- PaperA Framework and Representation for Universal Product DesignDaniel A. McAdams & Vincent Kostovich, 2011· Free
Proposes a way to represent a product's function so that a designer can systematically check it against the needs of users with different abilities, arguing that universal design has lacked the concrete method engineering design already has for ordinary requirements.

143- Talk10+ Deploys Per Day: Dev and Ops Cooperation at FlickrJohn Allspaw & Paul Hammond, 2009· Free
Argues that deploying code many times a day is safer than deploying rarely, because it forces developers and operations to share tools and incentives instead of treating a release as a handoff between adversaries — the talk that gave the DevOps movement its founding example.
- ReportA Brief History of Deposit Insurance in the United StatesFederal Deposit Insurance Corporation, 1998· Free
Traces federal deposit insurance from more than 150 failed state-level schemes before 1933 to the FDIC, arguing insurance worked nationally only once it was compulsory, federally backed and paired with real bank supervision.

Surveys the evidence on when and why managers exercise discretion over reported earnings, and argues standard setters should worry less about whether judgement is used at all and more about whether it is used to mislead.
- PaperA Tutorial on the McKinsey Model for Valuation of CompaniesL. Peter Jennergren, 1998· Free
Works through the discounted cash flow valuation model popularised by Copeland, Koller and Murrin step by step, including how the continuing (terminal) value term is derived and where it can be misapplied.
- BookA Work on Bridge BuildingSquire Whipple, 1847· Free
Applies statics directly to truss bridges for the first time, deriving the force in every member algebraically instead of by rule of thumb, and argues a bridge should be designed from calculated loads rather than copied from a builder's precedent.
- PaperAgency Costs of Free Cash Flow, Corporate Finance, and TakeoversMichael C. Jensen, 1986· Paid
Argues that managers holding free cash flow beyond what profitable projects require tend to waste it on low-return acquisitions or empire-building, and that debt disciplines this by pre-committing cash to creditors.
- BookAn Elementary Treatise on the Dynamics of a Particle and of Rigid BodiesS. L. Loney, 1909· Free
Builds up particle and rigid-body dynamics — momentum, energy, impulsive forces, rotation about a fixed axis — as a sequence of solvable problems, the form in which the subject was taught to a century of engineering students.
- PaperAn Empirical Evaluation of Accounting Income NumbersRay Ball & Philip Brown, 1968· Paid
Shows that a company's stock price drifts in the direction of its eventual reported earnings surprise for months before the announcement, giving the first direct evidence that accounting income numbers carry real information investors act on.

- PaperA Probabilistic Earley Parser as a Psycholinguistic ModelJohn Hale, 2001· Free
Models a parser's difficulty at each word as the change in a probability distribution over remaining analyses, showing this single information-theoretic quantity predicts where readers slow down without needing a separate garden-path mechanism.
- EssayA Scheme for a New Alphabet and a Reformed Mode of SpellingBenjamin Franklin, 1779· Free
Proposes discarding redundant letters and adding new ones so that English spelling represents pronunciation directly, on the grounds that a phonetic alphabet would be faster to learn and harder to misread.
- PaperA Simplest Systematics for the Organization of Turn-Taking for ConversationSacks, Schegloff & Jefferson, 1974· Free
Argues ordinary conversation follows a small set of turn-allocation rules, operating locally turn by turn, that explain how speaker change happens with minimal gap or overlap without anyone directing it.

link checked 17 Sept 2026 - PaperA Behavior Model for Persuasive DesignB. J. Fogg, 2009· Paid
Proposes that a behaviour occurs only when motivation, ability and a trigger converge at the same moment, so a failed behaviour change is best diagnosed by asking which of the three was missing rather than prescribed more willpower.
- PaperA Fine Is a PriceUri Gneezy & Aldo Rustichini, 2000· Free
A field experiment at daycare centres finds that introducing a modest fine for picking children up late increased the rate of late pickups rather than reducing it, arguing that a price reframes a social obligation as a market transaction and removes the guilt that previously did the deterring.
