This dissertation investigates the effects of Message Timeliness (the speed at which a response to a message becomes available to the sender of an original message) and Message Addressability (the ability to target a response message to a source message) on decision making in groups using collaborative technology. Message Timeliness and Message Addressability were studied in two contexts, within and across two types of collaborative technology. The collaborative technology used in this research was an Electronic Meeting System. Two laboratory experiments were employed to manipulate the independent variables. Both studies incorporate a 2 x 2 design. The first study crosses Message Timeliness (the speed at which a response to a message becomes available to the sender of a original message) with Media (two different software programs within the EMS), and examines its impact on convergent group behavior at the individual and group level. The second study crosses Message Addressability (the ability to target a response message to a source message) with Media. Dependent variables were the same as in study one. The subjects, upper-level, undergraduate business students, were asked to discuss a human resource task and come to a unanimous group decision. The collaborative technology used for communication in this study allowed for group members to enter, and then send their comments to the other group members in a non-anonymous manner. Measures of convergence, for both studies, were taken at the individual and group level. Mediating variables were measured using questionnaires which were administered after the task was completed. For study one, Message Timeliness was found to have a positive significant relationship with the three mediating variables Conversational Coherence, Attribution of Effort, and Satisfaction with Process. Conversational Coherence and Satisfaction with Process were found to have a positive significant relationship with Group Consensus measured on the individual level. The relationship with Attribution of Effort was also significant, but negative. Satisfaction with Process also had a positive significant relationship with Individual Convergence. In study two, Message Addressability (MA) was found to have a significant positive relationship with both Conversational Coherence and Satisfaction with Process.

<p> Communication is one of the key causes of healthcare-related harm. An estimated 210,000 to 400,000 deaths each year in the United States are attributed to healthcare-related harm. Interprofessional communication and collaboration have been identified as critical to providing safe care. Documentation is intended to support interprofessional communication and collaboration. However, research has demonstrated that documentation in the electronic health record (EHR) is not regularly used to support interprofessional communication. Previous research has examined the use of the patient record for information sharing and has identified several barriers that inhibit its use for communication; yet, little is known regarding how the record <i>ought to be used</i> for interprofessional communication. </p><p> Healthcare-associated infections (HAI), including central line associated-blood stream infections (CLABSI), is one category of healthcare-associated harm. The purpose of this study was to describe, using the Delphi technique, what an expert panel of nurses and physicians believe regarding how the EHR ought to be used to optimize interprofessional communication in central venous catheter (CVC) management and prevention of CLABSI. The study was guided by the frameworks of Distributed Cognition and Coiera&rsquo;s Communication Space. </p><p> The expert panel consisted of six nurses and four physicians from a large academic healthcare system who had experience caring for patients with CVCs and using the EHR for retrieving, documenting, and communicating information. The panel members held such positions as staff nurse, nurse leader, resident, attending, and physician leader/medical director. Four Delphi rounds, which included an initial individual interview followed by three survey rounds, were completed to achieve stability in panel member responses. </p><p> The panel identified 12 information types necessary for decisions regarding whether to keep or discontinue a CVC, the best channels for communicating each of the information types, and factors that promote or inhibit the use of the EHR for interprofessional communication. </p><p> The findings have implications for the creation of interprofessional practice guidelines, interprofessional education, and the development of EHRs that better support interprofessional communication and team-based care. Understanding how to optimize the EHR in order to leverage the knowledge captured in clinicians&rsquo; documentation has the potential to improve patient care and reduce harm.</p><p>

<p> Knowledge sharing among software developers enhances the success of software design and implementation. However, there is an inadequate understanding of how communication factors such as negotiation and reciprocity impact the knowledge-sharing process within software development teams and between team leaders and team members. The present study used a correlational research design to test the relationship between the reciprocity (i.e., communication between team members), negotiation (i.e., communication between team leaders and team members), and knowledge sharing to determine whether different types of communication influence knowledge-sharing outcomes. A cross-sectional survey was used to collect data from a target population of software developers. The sample consisted of 85 software developers with a minimum of 2 years of experience working on software development teams. Multiple linear regression analyses were run to determine the extent to which the variables of negotiation, reciprocity, and knowledge sharing were related. The results indicated that the variables were significantly related, and 70% of knowledge sharing was the result of reciprocity-exchange of ideas and reciprocity-meetings. Team meetings and the open exchange of ideas between team members were found to be the most effective methods of reciprocity related to knowledge sharing among team members. Negotiation and team cohesiveness, however, were not significant to the knowledge-sharing process. The findings indicated that the process of knowledge sharing is more important than individual relationships between software development team members. Thus, from an organizational perspective, holding regular project meetings with all team members would be a more effective knowledge-sharing strategy than using team-building exercises to strengthen personal bonds between team members. Additional research is necessary to determine how software developers&rsquo; personal characteristics impact knowledge-sharing processes.</p><p>

<p> Insider threat by employees in organizations is a problematic issue in today&rsquo;s fast-paced, internet-driven society. Gone are the days when securing the perimeter of one&rsquo;s network protected their business. Security threats are now mobile, and employees have the ability to share sensitive business data with hundreds of people instantaneously from mobile devices. While prior research has addressed social networking topics such as trust in relation to information systems, the use of social networking sites, social networking security, and social networking sharing, there is a lack of research in the mindfulness of users who spill sensitive data contained within images posted on social networking sites (SNS). The author seeks to provide an understanding of how non-malicious spillage through images relates to the mindfulness of employees, who are also deemed insiders. Specifically, it explores the relationships between the following variables: mindfulness, proprietary information spillage, and spillage of personally identifiable information (PII). A quasi-experimental study was designed, which was correlational in nature. Individuals were the unit of analysis. A sample population of business managers with SNS accounts were studied. A series of video vignettes were used to measure mindfulness. Surveys were used as a tool to collect and analyze data. There was a positive correlation between non-malicious spillage of sensitive business, both personally identifiable information and proprietary data, and a lack of mindfulness. </p><p>
