Automated legal sensemaking: the centrality of relevance and intentionality
Introduction: In a perfect world, discovery would ideally be conducted by the senior litigator who is
responsible for developing and fully understanding all nuances of their client’s legal strategy. Of
course today we must deal with the explosion of electronically stored information (ESI) that
never is less than tens-of-thousands of documents in small cases and now increasingly involves
multi-million-document populations for internal corporate investigations and litigations.
Therefore scalable processes and technologies are required as a substitute for the authority’s
judgment. The approaches taken have typically either substituted large teams of surrogate
human reviewers using vastly simplified issue coding reference materials or employed
increasingly sophisticated computational resources with little focus on quality metrics to insure
retrieval consistent with the legal goal. What is required is a system (people, process, and
technology) that replicates and automates the senior litigator’s human judgment.
In this paper we utilize 15 years of sensemaking research to establish the minimum acceptable
basis for conducting a document review that meets the needs of a legal proceeding. There is
no substitute for a rigorous characterization of the explicit and tacit goals of the senior litigator.
Once a process has been established for capturing the authority’s relevance criteria, we argue
that literal translation of requirements into technical specifications does not properly account for
the activities or states-of-affairs of interest. Having only a data warehouse of written records, it
is also necessary to discover the intentions of actors involved in textual communications. We
present quantitative results for a process and technology approach that automates effective
legal sensemaking
Exploring the performance reserve: Effect of different magnitudes of power output deception on 4,000 m cycling time-trial performance
Purpose
The aim of the present study was to investigate whether a magnitude of deception of 5% in power output would lead to a greater reduction in the amount of time taken for participants to complete a 4000 m cycling TT than a magnitude of deception of 2% in power output, which we have previously shown can lead to a small change in 4000 m cycling TT performance.
Methods
Ten trained male cyclists completed four, 4000 m cycling TTs. The first served as a habituation and the second as a baseline for future trials. During trials three and four participants raced against a pacer which was set, in a randomized order, at a mean power output equal to 2% (+2% TT) or 5% (+5% TT) higher than their baseline performance. However participants were misled into believing that the power output of the pacer was an accurate representation of their baseline performance on both occasions. Cardiorespiratory responses were recorded throughout each TT, and used to estimate energy contribution from aerobic and anaerobic metabolism.
Results
Participants were able to finish the +2% TT in a significantly shorter duration than at baseline (p = 0.01), with the difference in performance likely attributable to a greater anaerobic contribution to total power output (p = 0.06). There was no difference in performance between the +5% TT and +2% TT or baseline trials.
Conclusions
Results suggest that a performance reserve is conserved, involving anaerobic energy contribution, which can be utilised given a belief that the exercise will be sustainable however there is an upper limit to how much deception can be tolerated. These findings have implications for performance enhancement in athletes and for our understanding of the nature of fatigue during high-intensity exercise
Palaeoecological evaluation of the recent acidification of Lochnagar, Scotland
Lochnagar, a high altitude, relatively deep, come lake, lies on the Royal Deeside ESUHC of
Balmoral, in an area which experiences moderate levels of acid deposition, The loch catchment
comprises granite bedrock and is dominated by bare rock but overlain in places with blanket peals,
Lochnagar may thus be considered potentially susceptible to acidification, The contemporary pH of
the loch water is c. 5,0
