The document discusses the results of a study on the impact of COVID-19 lockdowns on air pollution. Researchers analyzed data from dozens of countries and found that lockdowns led to an average decline of nearly 30% in nitrogen dioxide levels across major cities. However, they also observed that the reductions in air pollution were temporary and that levels began to rise again as restrictions eased and human activity increased.

- #10: completeness - including no answer
- #11: this is how ive been investigating it grounding it in mspace
- #18: google
- #21: better video?
- #23: but i suffered the result-availability problem
- #24: wanted a quick method - applied to prototyes - earlier design bit like stephann makri’s info behaviour work, but at a lower seeking only level.
- #25: 10 mins? earlier?

- #37: how does it support tactics at each of these points
- #39: and then it uses the models to infer support for certain types of users.
- #46: hit at 18mins ish
- #49: not going to go into history - ann knows the history
- #50: these have increasing ecological validity
- #51: but that doesnt tell you if its a good method for practitioners not ‘recommended’ - tried with very newbies
- #54: Cockton - its not measuring time - effort but makes you think about each feature and how it *could* be designed doesnt impose design - or design decisions ‘moves’ is just not a suitable measure for that
- #55: prof keith lloyd - director health sciences swansea analyse current UI
- #56: try to hit at 25 mins
- #57: that was a bit of a large vision into the future but in the mean time - it turns out that there’s still a lot we dont know about these exploratory conditions for example.
- #59: information need is probably either:

- #65: actually its still going
- #66: 30 mins or earlier
- #69: only 10 of the 12 words
- #70: left col - trouble? right col - children!
- #71: browsing - its very time-passing - open ended exploring - in a fixed space. faceted browsing?
- #72: hunting will provide us with a lot of insight into the information scarcity problem
- #73: searching - not associated with time - but often with ‘best’ or ‘optimal’ answers seeking - people (inc porn) and truth/god etc investigating was never really associated with love, happy, or goodness but the police
- #74: tried tweets with emoticons and a ‘lingo training set’
- #75: hunting often negative - perhaps lots of fails? browsing is neutral exploring is positive?
- #76: exploring is more positive, and browsing is very neutral browsing often to pass time
- #77: positive investigation == successful results? hunting, however, includes aptlist in the negative
- #80: retrieval is procedureal - perhaps the driving force of the IR community? ‘faceted browsing’ - browsing is actually just open ended passing time - chaining and random paths ES - understanding the breadth of something or checking them all Inv. - hidden dependancies (ben s)
