-In one study, forthcoming in American Behavioral Scientist, I test
-several of the most widely cited theories associated with
-``generativity'' (i.e., qualities of technology or content that make
-some works more fertile ground for collaboration). I find some support
-for existing theory but also find that, across the board, factors
-associated with more collaboration are also associated with less
-original and transformative types of joint-work
-\cite{hill_remixing_2012}. In another study of Scratch, I show that
-this type of superficial collaboration leads to negative reactions and
-community displeasure \cite{hill_responses_2010}.

In a study of status-based awards in Wikipedia called ``barnstars''
-(see Figure \ref{fig:barnstar}) I provide an empirical test of an
-influential status-based theory of collective action from
-sociology. Although the study finds support for the widely
-hypothesized ``virtuous cycle'' of status rewards both causing and
-being caused by contributions, it also finds that this effect is
-limited to a sub-population of Wikipedia contributors -- ``signalers''
-who show off their awards \cite{hill_status_2012}. This result
-has broad implications for both status-based theories of collective
-action as well the design of reputation-based rewards.
-
-In a mixed methods study of Scratch, nominated for best paper at the
-CHI 2011 conference \cite{monroy-hernandez_computers_2011}, I
-present both a quantitative analysis of a design change and in-depth
-interviews of users to demonstrate how credit-giving is ineffective
-when it stems from an automated system because systems fail to
-reinforce status-ordering with credible human expressions of social
-deference and gratitude.

the effort and contributions of established participants.
-In other work, I have analyzed sales records of hobbyist
-microcontrollers to argue that relatively simple design changes in the
-\emph{LilyPad Arduino} -- a electronics toolkit minimally re-designed
-for women and girls (see Figure \ref{fig:lilypad}) -- lead to large
-increases in the proportion of women contributors and drastic shifts
-in the type of projects created \cite{buechley_lilypad_2010}. I have
-also explored how technical errors may be able to provide similar
-opportunities for analysis \cite{hill_revealing_2010}.

% or changes in socio-technical systems describing responsibility for a piece of software can lead to an important impact in the type and structure of contributions in peer production \cite{michlmayr_quality_2003}
datasets, I plan to compare the performance of collaborative
production to individually produced works to understand when
successful collection action leads to increased performance. For
-example, in a manuscript currently under review using data from
-Scratch, I show important limitations of collaboration through
-remixing in regards to project quality, particularly for more artistic
-or media-intensive works \cite{hill_cost_2012}.
