Increasingly, workplace information seeking takes place in digital information environments and is reliant upon search systems. Existing systems are designed to retrieve information that is relevant to the query, but are not capable of identifying information that is well-suited to the context and situation of a search. This is a problem for professionals who often are searching for a small amount of useful information that can be applied to a problem or task, and have limited time to browse through large sets of results. This inability of search systems to discriminate between relevant and useful documents is one of the core problems in information retrieval. In this dissertation, I address this problem by studying the role that contextual factors play in determining how a group of professionals searches for and selects information. The central question concerns the nature of the relationships between these contextual factors, specifically between the genres in the document collection and the tasks of the searcher, with an aim to exploit such relationships to improve workplace information retrieval. Research was conducted through multiple studies in three phases, moving from an exploratory study of workplace information behaviour to a controlled experimental user study. Findings confirm that workplace context shapes search behaviour. This relationship is modeled as a set of key contextual factors and sets of context-dependent access constraints, preferred document characteristics, and search strategies. Among the contextual factors identified, work tasks and information tasks were found to be significantly associated with document genres. This task-genre relationship was modeled as a matrix of associations between domain-specific task and genre taxonomies and successfully implemented as a filtering component in a workplace search system. This is the first major study of the relationship between task and genre in information seeking and of its application to information retrieval systems.

Digital stories--two- to five-minute videos consisting of a first-person voiceover set to a slideshow of personal photographs--combine personal reflection with digital technologies. The stories and the process of making them appeal to many organizations, particularly those with a mission of outreach or education. However, despite the inexpensive and fairly easy-to-use digital technologies involved, organizations have typically had difficulty implementing the practice. This dissertation presents a case study of one organization that hoped to implement digital storytelling, detailing the 15 months after its Writing Director completed a digital storytelling train-the-trainer workshop. The case study organization, Tech Year, is a one-year intensive college and job-readiness program for urban 18-24 year-olds. The case study aims for descriptive detail, and reflects 300+ hours of site visits, 29 interviews, and extensive document collection. Everett Rogers' theory of organizational innovation is used to frame the case study description. Tech Year hoped to integrate digital storytelling into its Business Writing curriculum and imagined a number of other utilities for digital storytelling related to fundraising, recruiting, and student development. During the 15-month research period, a wide range of digital storytelling-related activity happened at Tech Year, including a pilot of digital storytelling in the Business Writing classroom. At the conclusion of the study, however, Tech Year had not settled on a sustainable organizational use or uses for digital storytelling, and organizational members were uncertain whether the practice would persist. Besides telling an implementation story, the study has a second major aim: to explore theoretically informed reflective tools that might be used by researchers and organizations to assess and direct ongoing digital storytelling implementation efforts. A novel methodology that examines digital storytelling pilots through the lens of North American genre theory, called genre-informed implementation analysis, is both described and applied to the case of Tech Year.

In this thesis, I ask about the descriptive purchase on discursive events of some accounts of speech as action. To do so, I turn to speech act theory, which I read at first restrictively, and later more broadly, moving from John Langshaw Austin to John Rogers Searle to Judith Butler, appealing along the way to Charles Sanders Peirce, Ludwig Wittgenstein, Jean-François Lyotard and Mikhail Mikhailovich Bakhtin. In so doing, I construe speech act theory as a genre (or set of genres) of theoretico-critical inquiry. By genre I mean a set of differentiated, recurrent forms of practice which have their own functions or ends, their own means, protocols and postulates: their own speaking positions and objects of representation or inquiry. For my purposes, then, speech act theory denotes a capacious genre of inquiry turning on the topic of speech as action. I take this topic to raise a range of rhetorical issues concerning the pragmatic question of discursive linking. To talk of discursive linking, I suggest, is minimally to presuppose notions of semiosis, of rhetorical situation or occasion and of rhetorical agency, with its attendant postulates of intention and responsibility. I thus read speech act theory rhetorically, as an open set of engagements with the question of how we do things with words: how utterances come to count as action, and how utterance action is described as having determinate consequences and effects. I begin in chapter 1 by reading Austin for his two tensively related, if not countervailing, descriptive tendencies: those of illocution and perlocution. In chapter 2, I attend to Searle as an exemplary development of an illocutionary inquiry, before examining Butler’s work on hate speech and performativity as a type of perlocutionary inquiry in chapter 3. Illocution and perlocution, I suggest, comprise distinct engagements with the questions of speech as action and discursive linking. Although postulates of semiosis and situation, and figures of responsibility, intention and agency are put to work in both illocutionary and perlocutionary inquiries, in each they work differently. This differential work, I argue, marks the differing capacities of illocutionary and perlocutionary inquiries adequately to describe a discursive event. Different construals of speech as action tell different tales of uptake or linking, enabling and constraining different accounts of discursive events. With this in mind, I turn by way of an extended example in chapter 4 to the caso Belsunce, a high-profile homicide case begun in Argentina in 2002. I do so to suggest that a focus on utterance actions as semio-discursive events relates the perlocutionary concerns discussed in chapters 1 – 3 to postulates of cultural memory-work, kairos and rhetorical community. Taken together, this range of concerns helps us to describe the mediatic uptake of the Belsunce case as a particular, complex semio-discursive event. But a description of a discursive event is of course itself a sign, something which, as Peirce notes, ‘stands to somebody for something in some respect or capacity’ and which strives, in turn, to determine subsequent interpretant effects. In this respect, the critical description of discursive events is itself an instance of speech as action which cannot but continue to raise hermeneutic, rhetorical and semiotic questions of discursive upshot or uptake.
