Phil 7.11.17

7:00 – 8:00 Research

  • Played around with the lit review section using LMN. Here’s a screenshot of the docs as of yesterday: LMN_screenshot_7.11.17
  • Continuing C&C
    • Thus, as a hypothesis concerning the polarization of groups, it may be concluded that the consensus reached will be the more extreme:
      (a) when individuals participate more directly in the discussions;
      (b) when the differences between them, their knowledge and their opinions are more marked;
      (c) when what is at stake in the discussions is perceived by them as valuable. [p 67]

      • What interests me here is (b). I think that there are several measures of difference that matter
        1. The information distance, as determined by amplitude and variance. There is a difference between agreement about two extreme positions that are broadly based and two narrow positions.
        2. The heading alignment. It is possible to arrive at a position from different directions. Is it easier if the headings are similar?
        3. Velocity. Is there a situation where one piece of information is held fixed and everything else is allowed to change? (e.g. The Leader is always right, though the position is in constant flux [Trump supporters know Trump lies. They just don’t care.])
        4. Exogenous visibility. What does the information horizon look like to the discussants? Do they feel as though they are relatively close or far apart? The VI/Emacs disagreements seem both vast and trivial, depending on framing, for example.
    • Plainly, there is no halo effect on questions that are not included in it (the discussion) [p 69]
      • So in emergent groups, what is the discussion? Or do we look for polarizing behavior and infer the point of discussion from that? I think that this implies axis on a dimension-reduced map that might make sense. 
    • we assumed that where discussion had created tension, shifts in the direction of a consensus should be more frequent. To verify this, the distance was measured between the two individuals whose opinions diverged most before the beginning of the discussion. A distance of 1 meant that these two opinions were separated by one point on a seven-point attitude scale. The opinions of the others, whether identical or not among themselves, were located between those of the two individuals who differed most. In the same way a distance of 6 meant that one of the individuals in the group was located at the favourable pole and another at the unfavourable pole. Thus they were opposites; the opinions of the rest were distributed between these poles. It is here, where conflict was greatest, that the maximum polarization should be recorded. In fact, the shifts towards an extreme consensus turned out to be more frequent in the groups when the gap was more than three points than when it was below that figure. [p 69]
    • The finding was simple: the common choices were much more extreme in the groups of five than in those of four, which themselves were more extreme than those in the groups of three. Moreover, they polarized more when they engaged in discussion among themselves than when they proceeded to a silent exchange of notes [p 70]

9:00 – 4:30 BRC

  • Setting up test instance
    • CrawlService – Cloned
    • NLPService – Cloned
    • MasterDataService – Cloned
    • gtc-test-fixtures – Cloned
    • Added Chrome and Postman
    • Added the rmq dash: sudo rabbitmq-plugins enable rabbitmq_management, which runs at http://localhost:15672 with default login and password of guest
    • MasterDataService runs and is visible here: http://localhost:8890/masterdataservice/events
    • To make things easier to run, added a slew of aliases:
      alias mrmq='sudo rabbitmq-plugins enable rabbitmq_management'
      alias ovpn='cd /home/pfeldman/openVPNconfig && sudo openvpn --config bellrock.ovpn && cd ..'
      alias run_crawl='java -jar /home/pfeldman/IdeaProjects/CrawlService/build/libs/crawlservice.war &'
      alias run_geocoder='java -jar /home/pfeldman/IdeaProjects/GeoCoderService/build/libs/geocoderservice.war &'
      alias run_mds='java -jar /home/pfeldman/IdeaProjects/MasterDataService/build/libs/masterdataservice.war &'
      alias run_nlp='java -jar /home/pfeldman/IdeaProjects/NLPService/build/libs/nlpservice.war &'
      alias startdfs='/home/pfeldman/hadoop-2.7.3/sbin/'
      alias starthbase='/home/pfeldman/hbase-1.3.1/bin/'
      alias startrmq='service rabbitmq-server start'
      alias stopdfs='/home/pfeldman/hadoop-2.7.3/sbin/'
      alias stophbase='/home/pfeldman/hbase-1.3.1/bin/'
      alias stoprmq='service rabbitmq-server start'
    • Have the full stack running, but was unable to get crawlservice running with this payload from scheduling service:
