Have your cake and eat it too: how invoking post-purchase hyperopia mitigates impulse purchase regret

You can't have your cake and eat it too.

Introduction I always feel guilty when I go see the dentist. We all know the rules—avoid sweets, brush after every meal, floss several times a day. Talking about tool and shop safety gets the same treatment in articles and books– always read the owner’s manual, inspect your tool for hazards daily, make sure your tools are properly grounded (sound familiar?) The challenge I present to you is tha...

The Perfective Paradox: or How to Eat Your Cake and Have It Too

Event Systems: How to Have Your Cake and Eat It Too

This paper addresses the fundamental tradeoffs in event systems between scalability (of event filtering, routing, and delivery mechanisms), expressiveness (when describing interests in events), and event safety (ensuring encapsulation and type-safe interaction with polymorphic events). We point out some ramifications underlying these tradeoffs and we propose a pragmatic approach to handle them....

Have Your Cake and Eat It Too: The Old Principal Principle Reconciled with the New*

David Lewis (1980) proposed the Principal Principle (PP) and a “reformulation” which later on he called ‘OP’ (Old Principle). Reacting to his belief that these principles run into trouble, Lewis (1994) concluded that they should be replaced with the New Principle (NP). This conclusion left Lewis uneasy, because he thought that an inverse form of NP is “quite messy”, whereas an inverse form of O...

Have Your Cake and Eat it, Too: Data Provenance for Turing-Complete SQL Queries

We report on our work about the computation of data provenance for feature-rich SQL. Among further constructs, our prototype supports correlated subqueries, aggregations, recursive queries and window functions. Our analysis approach completely sidesteps relational algebra and instead requires a translation of the input query into an imperativestyle program. Provided that the target language is ...
