This project aims to assess the influence of using smart phones on pedestrians’ visual attention and safety. To do so, the developed methodology employs electroencephalography (EEG) and behavioral measures. Participants will be using the text messaging functionality of a smart phone while walking on a treadmill. The experiment will take place in an immersive 3D environment at the Optometry School of the University of Montréal. The experiment will take place during the month of May 2014. Twenty participants will be recruited (between 20 and 34 years old). They will have owned a smart phone for at least 6 months and use it occasionally while walking. The poster will present the complete methodology and acquisition setup along with preliminary results.
Faced with growing pressures to be more environmentally sustainable, many companies are increasingly exploring innovative ways to incorporate "green" practices into their business processes. We focus on employees and their potential contributions to organization-wide sustainability goals through their pro-environmental behaviours. This article reports on current progress with a multi-year study targeting the use of mobile media to encourage pro-environmental behaviours. To do so, we provide employees with feedback on their computer-based energy usage. We discuss our combined design science and experimental approach to developing and studying a mobile application with embedded persuasive characteristics. Our future interventions will use this persuasive media platform to examine the impact of social-psychological theories on encouraging more sustainable energy use by employees.
The main objective of this research is to investigate how input device type influences users’ memory retrieval (i.e., stimulus recognition). We build upon prior research on the somatosensory (tactile) system to argue that the use of a direct input device (i.e., touch screen) involves a multisensory experience and more cerebral activities than an indirect input device (i.e., mouse), leading to richer information encoding, and consequently to better information retrieval from memory. A one-factor between-subject experimental design was used to test our hypotheses. Thirty participants were randomly assigned to either a mouse or touch screen input device condition. Our results indicate that for individuals with higher need for touch, input device influences activity in the posterior parietal cortex (PPC), a brain region associated with multisensory experience, during memory retrieval and stimulus recognition.
Using cognitive neuroscience as a reference discipline, this study aims to investigate the effect of input device on brain activity, and the effect of these brain activities on the cognitive process of memory retrieval.
The ranking-type Delphi method is well suited as a means for consensus-building by using a series of questionnaires to collect data from a panel of geographically dispersed participants. This method allows a group of experts to systematically approach a particular task or problem. While information systems researchers have been using this method for almost three decades, no research to date has attempted to assess the extent to which Delphi studies have been rigorously conducted. Using the guidelines that have been prescribed by the leading Delphi methodologists, our descriptive review reveals many positive signs of rigor such as ensuring the anonymity of experts and providing clear and precise instructions to participants. Nevertheless, there are still several areas for improvement, such as reporting response and retention rates, instrument pretesting, and explicitly justifying modifications to the ranking-type Delphi method.

Il est suggéré que le flow influence l’inattention visuelle (i.e., cécité attentionnelle) et qu’il est déterminé en partie par la position corporelle de l’utilisateur et du niveau d’interactivité de la tâche effectuée.
As a result of newer communication technologies and an increase in virtual communication, employees often find themselves multicommunicating, or participating in multiple conversations at the same time. This research seeks to explore multicommunicating from the perspective of the person juggling multiple conversations at the same time-the focal individual. To better understand this phenomenon, we extend previous theorizing by including the concepts of the episode initiator (whether the second conversation was focal or partner initiated), the fit of the set of media used in the episode, one process gain (conversation leveraging), and process losses. Employing a series of pilot studies and a main study, the resulting model was analyzed using structural equation modeling, finding overall support for the model. Findings suggest that experienced intensity is an important factor influencing process losses experienced during multicommunicating, whereas episode initiator influences process losses and the process gain. Further, media fit moderates the relationship between intensity and process losses. The importance of multicommunicating in the workplace is discussed, the theoretical and practical contributions of this research are described, and limitations and suggestions for future research are outlined.
An important factor that can influence the user-analyst relationship during information systems development is how analysts communicate with users. The present study examines the extent to which analyst multicommunicating behaviors during meetings with users influence perceptions of the analyst and willingness to help the analyst with subsequent tasks. A research model was developed by integrating two streams of research, namely research on user-analyst relationships and multicommunicating. Using a 2X2 factorial experimental design and video vignettes depicting a series of meetings between an analyst and a user, data was collected from 80 participants. The results indicate that when the analyst engaged in multicommunicating, the study participants perceived significantly higher levels of analyst incivility, even when the analyst's multicommunicating did not interfere with or hamper his/her conversation with the user. In addition, perceived analyst incivility negatively influenced the participants' willingness to help the analyst in a future task. The paper then discusses the theoretical and practical implications of the study findings.
When teaching Information Systems (IS), one of the crucial objectives is to make students under-stand the practical aspects of the integration of IS in organizations. Over the last decades, several pedagogical approaches were introduced to more tightly bridge theory and practice, e.g., hands on exercises, simulations, real world projects, guest speakers, and case studies. In this paper, we in-troduce a pedagogical approach novel to IS which brings practice into the classroom, i.e., the live teaching case method. The live teaching case method is a hybrid between a guest speaker event and a teaching case. The live teaching case method is different from a written case as it is the an-imator who experienced the case who is verbally presenting the case. The live teaching case is different from a guest speaker event as it is more focused around specific decision points, such as a written case would be. We believe that the live teaching case approach alleviates several of the traditional case method shortcomings while maximizing the benefits associated with the presence of a guest speaker in class. This paper outlines the various steps involved in the live teaching case including initiating contact, planning the decision points, selecting student readings and develop-ing pre-course materials, guiding the initial presentation and discussion, guiding the presentation and discussion of the managerial decision points, and class wrap-up. This approach is explained and then illustrated using three different IS courses, namely, an IS project management course, a systems analysis and design course, and a capstone course on enterprise system implementation.
New communication technologies, increased virtual communication, and the intense pressure for managers and employees to be continually available and "online" are giving rise to a new and emerging workplace behavior: multicommunicating (MC), or the managing of multiple conversations at the same time. Whereas researchers in psychology and management have studied the phenomenon of multitasking, few have examined multitasking where one juggles not just multiple tasks but multiple people and often multiple media at the same time. We use the spiral theory of incivility to investigate the relational outcomes of MC from the perspective of the communication partners being juggled. Our research extends this theory by further exploring the starting point of the spiral and—through the application of social exchange theory—suggesting several antecedents to incivility that are important in the context of MC. Employing a survey methodology, both qualitative and quantitative data were collected to test the theory (n = 324) and were analyzed using qualitative thematic analysis and structural equation modeling. The results suggest several factors influencing the partner's perceptions of focal individual incivility during MC, including who initiates the conversation, whether one of the conversations being juggled is useful to the other conversation, the focal individual's performance during the conversation, whether the focal individual is more accessible to the partner, and whether the partner is certain of or only suspects the existence of the other conversation. Further, partners' perceptions of these factors are influenced by their individual orientations toward MC. Finally, the partners' perceptions of the focal individual's incivility influence their interpersonal trust in the focal individual.
Although the stressful nature of high risk exposure software projects and the adverse repercussions of stress on project participants and performance have long been recognized, there is still little research on the subject. This paper builds upon two foundations - the cognitive-transactional theory of stress and the concept of software project risk exposure - to propose a model of software project risk drivers as software project manager stressors and coping resources. The model posits that some software project risk drivers - core project characteristics and project objectives - play the role of stressors and that other risk drivers - project environment characteristics - play the role of coping resources. The model further suggests that software project managers are faced with both chronic stress and acute stress, which have different antecedents. This paper broadens current understanding of the role of software project risk drivers; it also contributes to knowledge on software project management by focusing on the emotional components this activity.
In order to thrive, small businesses are often advised to develop relationships with external organizations that have the potential to assist business development, survival, and growth. A focus on the external relationships of the small business underlines the vital importance of external resources in moving a small business toward increased success and profitability. Covering the period from 1990 to 2002, this paper reviews the small business literature as it relates to the use of these external relationships (such as organizational partnerships, networks, and alliances). In response to both academic and practitioner demand for further research in this area, an exhaustive analysis of the relevant literature was conducted and three “meta” research questions representing the connections within this literature were formed. The resource-based view of the firm, resource dependency theory, and punctuated equilibrium theory are proposed as useful starting points for exploring these research questions and can give direction for moving forward in this research area.
With increased global connectivity, managers are faced with new technologies and rapid organizational changes. For instance, organizations may adopt emerging technologies such as Instant Messaging in order to increase collaboration at a distance and to decrease communications costs. However, the impact and implications of these technologies for managers and employees often go far beyond the original intent of the technology designers. Consequently, in this study, instant messaging (IM) and its use in organizations were investigated through interviews with employees. Results suggest that critical mass represents an important factor for IM success in the workplace that IM symbolizes informality, and that IM is perceived to be much less rich than face-to-face communication. Further, results demonstrate that employees use IM not only as a replacement for other communication media but as an additional method for reaching others. With IM, employees engage in polychronic communication, view IM as privacy enhancing, and see its interruptive nature as unfair. The paper concludes by discussing research and practice implications for organizational psychologists.
This article uses a case study of an international student research project to provide insight into the range of design considerations associated with technology-based learning. In aiming to add value to the learning experience of our undergraduate business students, colleagues from three universities set out to design a project that would enable students to learn things that would be inaccessible by any other means. The article discusses the inherent structural constraints associated with international partnering and illustrates how new ways of working with others are needed in dealing with the issues and challenges that arise. Practical suggestions are offered for others considering a project of this nature.
