    1. This is associated with the e-learning development tool "Articulate Storyline." There are frequent blog posts and they are not limited to or exclusive to the Articulate products. Posts are brief and not all of the content will be new, but there are worthwhile tips to be had and they combine theory (not to the extent that an academic would) with practice. rating 3/5

    1. Testing and Confinement - source that utilizes globals is somewhat more difficult to test because one cannot readily set up a 'clean' environment between runs. More generally, source that utilizes global services of any sort (e.g. reading and writing files or databases) that aren't explicitly provided to that source is difficult to test for the same reason. For communicating systems, the ability to test system invariants may require running more than one 'copy' of a system simultaneously, which is greatly hindered by any use of shared services - including global memory - that are not provided for sharing as part of the test.

      Important limitation to understand.

    1. Heteroscedasticity

      Heteroscedasticity is a hard word to pronounce, but it doesn't need to be a difficult concept to understand. Put simply, heteroscedasticity (also spelled heteroskedasticity) refers to the circumstance in which the variability of a variable is unequal across the range of values of a second variable that predicts it.

    1. ocial networks is relational data

      This is different than traditional social science which focuses on independent and dependent variables. For SNA, all data is related to all other data; no variables are mutually exclusive. This is why SNA is fundamentally descriptive.

    1. descriptive analysis

      The challenge of descriptive research for traditional social scientists is the change in how questions are asked. Questions should focus on describing something in a deep and informative way. Traditional social science relies more on predictive and inferential analysis. Can I predict what will happen if this variable changes in this way? Research questions identify the independent and dependent variables. SNA does not have IV and DV so questions are more about revealing what is going on underneath; i.e. how do the members of corporations know each other?

    1. tudies the relationships we have

      I am a bit confused here...SNA focuses directly on the space between individuals. Our relationships live in this space. Traditional social science looks at the characteristics of individuals to see if they vary according to another variable, i.e. independent and dependent variables. There are no IV and DV in SNA, at least in basic SNA. More advanced SNA blends statistics and SNA data.

    1. how they influence our lives, and how individual behavior is shaped by these networks.

      Networks are what sociologists talk about all the time but our methods don't fully 'see' them. We find relationships between variables--i.e. race and class--and then discuss how this relationship is due to social forces. Networks are the way in which social forces exert power!
