This dissertation investigates the topic of scholarship in the Information Systems (IS) discipline through a series of three papers. The papers, presented in Chapters 2, 3, and 4, each delve into a specific chronological period of IS scholarship which are delineated into the past, present, and future. Chapter 2 elucidates the IS disciplines past by categorizing the entire corpus of extant research in the Association of Information Systems Senior Scholars Basket of eight journals. Clusters derived from these mainstream journal publications represent a thematic identity of the IS discipline. After analyzing the corpus altogether, further analysis segments the corpus into shorter, 5-year periods to illuminate the historical evolution of the themes. Lastly, interpretations of the trends and a recommendation to curate an IS Body of Knowledge are discussed. Chapter 3 surveys business school deans and IS academics eliciting their present social representations of the IS discipline. It then seeks the two groups feedback regarding their level of agreement with concerns attributed to the IS discipline as summarized in Ives and Adams (2012). Group responses are evaluated independently and are juxtaposed for between-group analysis. Then, additional concerns are gathered to ensure the full range of issues are represented. Network topic maps illustrate the findings, and interpretations are discussed. Group differences suggest that IS academics are more critical of the IS discipline than business school deans. In Chapter 4, an alternative research approach is offered for conducting future scholarship efforts in the IS discipline. A framework that organizes discourse on the emergent crowdsourced research genre is constructed. Prior to building the framework, a crowdsourcing process model is developed to conceptualize how problems and outcomes interact with the crowdsourcing process. The internal process components include task, governance, people, and technology. Then, the crowdsourcing process model is applied to eight general research process phases beginning with the idea generation phase and concluding with the apply results phase. Implementation of the crowdsourced research framework expounds phase-specific implications as well as other ubiquitous implications of the research process. The findings are discussed, and future directions for the IS crowd are suggested.

This experiment was a replication and extension of Pickel, Karam, and Warner's (2006) study by using wiretap evidence instead of hearsay. The design was a 2 (admissibility) X 2 (unusualness) factorial with a control group that had no critical evidence. Participants were 129 mock jurors who listened to an audio-recording of a trial and made some decision about the case. Results showed that the critical evidence had no effect on guilt judgments. However, the unusualness manipulation did have an effect on the memory of the critical testimony, in that the participants in the unusual groups had a better memory than the neutral groups. Explanations of the results are discussed, along with limitations and suggestions for future research. / Department of Psychological Science

Background and Purpose: Dental hygienists are targeted for practice expansion to improve public access to oral health care and, therefore, must demonstrate decision making capacity. This study aimed to identify and test the impact of factors influential in dental hygiene decision making. Organizational and gender factors were hypothesized to be most influential. Methods: A phased mixed methods approach was used. Phase I: A series of focus groups were conducted to inform a dental hygiene decision making model, which included key predictor variables and the outcome variable: decision making capacity. Phase II: Aspects of the model were tested via an electronic questionnaire and key informant interviews. Statistical and qualitative thematic analyses were conducted and then findings were merged for interpretation. Results and Interpretation: Focus groups yielded over 75 codes and 6 themes (+ 1 theme from the literature) comprising the model and guiding the survey. The survey had a 38% response rate, and moderate to weak correlations between predictors and the outcome measure were shown. The final statistical model demonstrated Individual Characteristics and graduating from a 3-year program together significantly predicted decision making capacity. When merged with the key informant qualitative data, Individual Characteristics were shown to be a product of broad environmental factors and educational preparation had a particularly strong influence. Conclusions: Individual characteristics and education are predictive of decision making capacity but are outcomes of broad structural influences. Thus, it is recommended that modifications are made to these structures to support dental hygiene decision making in expanded practice.

This thesis is concerned with the factors underlying both selection and use of evidence in the testing of hypotheses. The work it describes examines the role played in hypothesis evaluation by background knowledge about the probability of events in the environment as well as the influence of more general constraints. Experiments on information choice showed that subjects were sensitive both to explicitly presented probabilistic information and to the likelihood of evidence with regard to background beliefs. It is argued - in contrast with other views in the literature - that subjects' choice of evidence to test hypotheses is rational allowing for certain constraints on subjects' cognitive representations. The majority of experiments in this thesis, however, are focused on the issue of how the information which subjects receive when testing hypotheses affects their beliefs. A major finding is that receipt of early information creates expectations which influence the response to later information. This typically produces a recency effect in which presenting strong evidence after weak evidence affects beliefs more than if the same evidence is presented in the opposite order. These findings run contrary to the view of the belief revision process which is prevalent in the literature in which it is generally assumed that the effects of successive pieces of information are independent. The experiments reported here also provide evidence that processes of selective attention influence evidence interpretation: subjects tend to focus on the most informative part of the evidence and may switch focus from one part of the evidence to another as the task progresses. in some cases, such changes of attention can eliminate the recency effect. In summary, the present research provides new evidence about the role of background beliefs, expectations and cognitive constraints in the selection and use of information to test hypotheses. Several new findings emerge which require revision to current accounts of information integration in the belief revision literature.

Objective: To understand the experiences of the dialysis decision-making process from the perspective of the significant other, specifically their role, influencing factors and the supportive interventions of the interprofessional team. Method: An interpretive description qualitative study was conducted using individual interviews and results were triangulated with decisional conflict and decisional regret quantitative results. Results: Ten participants described their role as advocating, providing a positive outlook, ‘being with’ the patient, learning together, sharing opinions, and communicating about values, preferences, feasibility of options. Environmental factors that influenced decision making included unexpected life change, choosing life, and personal health problems. Factors related to implementation of the treatment modality decision were unanticipated events, relationship changes, recreational travel changes, and the caregiver role. Nursing interventions are required to realign treatment expectations. Relevance: Significant others have an important role in supporting the patient making the dialysis decision and are often instrumental in implementing the decision.

This study examined the location decisions of family physicians in Saskatchewan by determining the factors that influence family physicians’ location decisions, and identifying the major themes from the factors. The research employed a rational choice model as a basis to design the methodology and explain how Saskatchewan family physicians make their practice location and re-location decisions. A mixed method approach, including an on-line questionnaire survey and interviews with key health agencies, was used to collect and analyse data. Data from the survey were summarised using summary statistics and cross tabulation. Responses from stakeholder interviews were transcribed and analyzed using interpretive description method. The mixed method approach elicited a rich and detailed description of family physicians’ location decisions. Participants of the study ranked family concern, work-life balance and community influence as the most influential factors of family physicians’ location decisions. The fourth factor of locations decisions according the study was compensation. Although compensation was mentioned as a factor, it was recorded as the least influential factor among the participants of this research. Other factors that were identified as having some influence on practice location choices were respect and appreciation, and scope of practice. To conclude, the study found that location decisions are not only about identifying the major influential factors of practice location choices, but also involve finding a good match between family physicians and potential practice locations and communities. That is, family physicians’ preferences must match the characteristics of the potential communities. Based on the conclusion, the study made two policy recommendations regarding the matching between family physicians and communities. The first policy recommendation is strategic matching between family physicians and communities for more efficient and effective recruitment and retention. The second recommendation is providing strategic incentives to ensure access to family physician services for the population in communities that do not meet the requirements of the strategic matching.

An individual s decision to place a close family member in a nursing home is both difficult and crucial. To assist consumers with such a decision, several initiatives have led to the creation of public websites designed to communicate quality indicators for nursing homes. However, a majority of consumers fail to fully utilize this information for various reasons, such as the multidimensionality, complexity, and uncertainty of the information. Some of the difficulties may be alleviated by information visualization (InfoVis) techniques. However, several unsuccessful attempts in applying InfoVis to decision making suggest that a thorough understanding of the user s perspective is necessary. Accordingly, the author has developed an InfoVis tool for the decision domain of choice of a nursing home. First, a framework of overarching InfoVis and decision theories, called the visualized decision making (VDM) framework, has been developed and contextualized within the selection of a nursing home. Second, a decision-support tool using several InfoVis techniques such as the weighting slider bar and the distribution view have been designed for application within the framework, and the designed tool, called VDM, was implemented. Third, VDM was empirically tested through a web-based experiment and follow-up interviews. The results of this study showed that individuals faced with the decision of selecting a nursing home could make fairly high quality decisions when they used VDM. Though the effects of proposed InfoVis techniques were not evident, this study provided the theoretical framework and empirical results which may help other designers of InfoVis techniques because this work addresses several issues consumers face when choosing a nursing home that can be generalized to other decision making contexts.
