stable demand of expectations. Stability nor fixity can be directly affected by the subject at hand. The only option is affecting homogenization which in turn, can positively or negatively affect stability. Directly choosing a fixed arena within genre inversely alters the homogenization of said chooser constituting as a new genre accompanied with modified genre subsets and a newly desired urgency. The same ideological theory can be applied to how one serves different purposes, creating either separate genres or modernized micro-genres. (Fairclough) Genre ecology and activity theory Activity theory is not grounded in any one area of field of research, but instead draws from several disciplines including psychology, behaviorism, and socio-cultural studies. Although activity theory originated in the social sciences, it is currently applied most frequently to social-scientific, organizational, and writing studies. Modeled as a triangle, activity theory considers how multiple factors (subject, object, mediating artifacts, rules, and division of labor) existing in an activity system (environment) interact to achieve an outcome. Central to activity theory is the concept of mediation. Human activities are driven by a need to achieve a certain outcome or goal. Typically this activity is mediated by artifacts which include tools, language, signs, and cultural norms. In "Textual Objects" Cheryl Geisler explains that texts are traditionally identified as meditational means to complete a task, though she offers that texts might also be identified as the motive in discourse communities in which text is valued as the outcome as opposed to the means of an outcome. Geisler notes that texts produced for meditational means are typically more private/personalized, whereas texts identified as objects are often written with a public motive. She does not argue, however, that texts should exist exclusively as one or the other, but rather she suggests that texts can function as both. For some genre theorists, such as Clay Spinuzzi, genres are tools-in-use, and as such can be seen as mediating objects within the world. This view of genre as a tool-in-use is exemplified in the school of genre theory that studies genres' relationships to activity systems. In his article "Textual Grounding: How People Turn Texts into Tools," Jason Swarts asserts that users utilize texts as tools when they recognize the text's specific value in a rhetorical situation or environment. User's then "ground" texts, altering the texts structure for personal use, to make them usable under very specific conditions. The user takes the text from
