The Impact

There is an increasing interest in the use of intelligent virtual agents (IVAs) to work in teams with humans. To achieve successful outcomes for these heterogeneous teams, many of the aspects found in successful human teams will need to be supported. These aspects include behavioural (i.e., multimodal communication), cognitive (i.e., a shared mental model (SMM)), and social (trust and commitment). Novelly, this paper aims to investigate the impact of IVA’s multimodal communication on the development of a SMM between humans and IVAs. Moreover, this paper aims to explore the impact of the developed SMM on a human’s trust in an IVA’s decisions and a human’s commitment to honour his/her promises to an IVA. The results from two studies involving a collaborative activity showed a significant positive correlation between team multimodal communication (i.e., behavioural aspect) and a SMM between teammates (i.e., cognitive aspect). Moreover, the result showed that there is a significant positive correlation between the developed SMM and a human’s trust in the IVA’s decision and the human’s commitment to honour his/her promises (the establishment of the social aspect of teamwork). Additionally, the results showed a cumulative effect of all of these aspects on human–agent team performance. These results can guide the design of human–agent teamwork multimodal communication models.

The Impact

This study takes a direct observation research approach to examine how the impact of collaboration mode on team productivity and process satisfaction is mediated by shared mental model. Team cognition and social impact theories are integrated to provide a framework for explaining how technology-mediated collaboration constrains or enhances team shared mental model development and its subsequent impact on task outcomes. Partial least squares analysis revealed that technology-mediated collaboration impacts shared mental model development. The results also demonstrate that timely and accurate development of shared mental model facilitates increases in both productivity and team process satisfaction. Direct observation of team process behaviors suggests that collaboration modes differ not only in their impact on communication facilitation but efficacy-based, motivational, and social influence factors (e.g., self-efficacy and team-efficacy, perceived salience and credibility of contributions, social influence on action, etc.) as well. Shared mental model development requires quality communication among team members that are motivated to participate by a positive team climate that promotes idea convergence.

OBJECTIVES/SPECIFIC AIMS: This study aims to examine the relative impact of aortic arch and carotid artery anatomy on the procedural times and clinical outcomes in patients who have suffered acute ischemic strokes (AIS). Mechanical thrombectomy remains the gold-standard of care for large vessel ischemic stroke. Given that short procedural times are necessary for good clinical outcomes, arterial access is an important technical consideration. It has been recently demonstrated that abnormal carotid artery anatomy can increase endovascular procedure times in this patient population. However, there are no studies examining the impact of aortic arch anatomy on operative times. Additionally, no studies have looked at the impact of aortic arch and carotid artery tortuosity on clinical outcomes in AIS. Thus, we sought to exam the influence of various aortic arch and carotid artery anatomic variables on interventional procedure times and clinical outcomes. METHODS/STUDY POPULATION: We included 56 patients who underwent embolectomy with successful revascularization for acute ischemic stroke in the anterior circulation from a period of 01/2016-05/2018. The average age was 71 (+/− 17 years) with 39% being male. We calculated anatomic variables on the affected side from CT angiograms immediately prior to embolectomy including the medial-to-lateral span, as well as the anterior-to-posterior span, of both the aortic arch and carotid arteries. In addition, the take-off angle of the respective vessel (left common carotid or right brachiocephalic) was calculated. Charts were reviewed for procedural times and epidemiologic information (HTN, HLD, DM, CAD and Afib). Modified Rankin Scale (mRS) was calculated from PT/OT and outpatient neurology notes. Partial correlation coefficients were performed between anatomic variables, temporal variables and outcome variables after adjustment for age, gender and epidemiologic information. RESULTS/ANTICIPATED RESULTS: There was a significant positive correlation between procedure time (time at groin puncture to time at reperfusion) and take-off angle. There were no other significant correlations between anatomic measures and procedure time. In addition, there was as a significant positive correlation between both procedure time and time from last seen normal to reperfusion and delta mRS (the difference between pre-stroke and post-stroke mRS). DISCUSSION/SIGNIFICANCE OF IMPACT: These results suggest that patients with larger take-off angles have an association with longer procedural times and worse outcomes. If these patients can be effectively identified prior to the procedure, operators could feasibly use a non-femoral access method initially to reduce procedure time.

58 Background: American Society of Clinical Oncology guidelines support early integration of palliative care (PC) into standard oncology practice; however, little is known as to whether improved outcomes can be achieved by modifying health care delivery and training oncology providers. Methods: We report our five year experience of embedding a nurse practitioner (NP) in an oncology clinic (March 2014-March 2019) to develop a shared mental model (SMM) of early, concurrent advance care planning (ACP) and PC as well as the collaborative effort to further disseminate this SMM throughout the Division of Hematology-Oncology using communication training, quality measurement, audit and feedback, leadership support, and monthly collaborative meetings. We developed PC quality metrics (process measures and end of life utilization measures) using a validated advanced cancer denominator. We used these measures to evaluate the impact of the PC-NP program (2014-2019) and provide individualized metric packets to each oncologist in the context of an annual half-day interactive communication training sessions (1-hr didactic, 3-hr small group role-play) each spring and monthly implementation team meetings from 2017-2019. Results: Compared to patients with advanced cancer not seen by the PC-NP program, patients who are enrolled in the program have higher rates of goals of care note documentation (80% vs. 17%, p < 0.01), higher rates of Physician Orders for Life Sustaining Treatment (POLST) completion (19% vs. 5%, p < 0.01), higher referral rates to the psychosocial oncology program (51% vs. 25%, p < 0.01), and higher referral rates to hospice (60% vs. 33%, p < 0.01). Among decedents, there was less hospital use (12 vs. 18 days) and ICU use (1.5 vs. 2.6 days) in the last 6 months of life. Since spring 2017, 19/21 NP’s, 64/68 physicians, and 17/20 fellows have participated in communication training. Among all patients with advanced cancer, goals of care note documentation has improved from 3% in March 2014 to 21% in March 2019. Conclusions: Embedding a trained PC-NP in oncology clinics to deliver upstream PC to patients on active treatment can lead to opportunities for development and dissemination of a SMM that translates into better primary and specialist PC.

The Impact

Adaptation is a key mechanism in human–human interaction. In our work, we aim at endowing embodied conversational agents with the ability to adapt their behavior when interacting with a human interlocutor. With the goal to better understand what the main challenges concerning adaptive agents are, we investigated the effects on the user’s experience of three adaptation models for a virtual agent. The adaptation mechanisms performed by the agent take into account the user’s reaction and learn how to adapt on the fly during the interaction. The agent’s adaptation is realized at several levels (i.e., at the behavioral, conversational, and signal levels) and focuses on improving the user’s experience along different dimensions (i.e., the user’s impressions and engagement). In our first two studies, we aim to learn the agent’s multimodal behaviors and conversational strategies to dynamically optimize the user’s engagement and impressions of the agent, by taking them as input during the learning process. In our third study, our model takes both the user’s and the agent’s past behavior as input and predicts the agent’s next behavior. Our adaptation models have been evaluated through experimental studies sharing the same interacting scenario, with the agent playing the role of a virtual museum guide. These studies showed the impact of the adaptation mechanisms on the user’s experience of the interaction and their perception of the agent. Interacting with an adaptive agent vs. a nonadaptive agent tended to be more positively perceived. Finally, the effects of people’s a priori about virtual agents found in our studies highlight the importance of taking into account the user’s expectancies in human–agent interaction.

\<p>The study aimed to identify the nature of the relationship between dialogue culture of college of education students at Najran University and their psychological compatibility. In addition, it aimed to define the impact of age variable on this culture. It also tried to explore the possibility of predicting the level of these students’ psychological compatibility by variables of dialogue culture. The study instruments involved a scale for measuring university students’ dialogue culture prepared by the researchers in addition to a test for psychological compatibility prepared by Shoqir (2003). The sample consisted of all students enrolled in “Learning Disabilities” course in the second semester of the academic year 2014/2015. Findings showed a significant positive correlation (α=0.01) between students’ dialogue culture and all dimensions of their psychological compatibility. There were differences between 19-year old students group and 22-year old students group in favor of the latest due to cognitive, affectional and behavioral levels of dialogue culture. Findings also indicated that the three dimensions of dialogue culture (cognitive, affectional and behavioral) could predict the psychological compatibility levels of students of “Learning Disabilities” course at the college of education.</p>

The Impact

An emerging research agenda in Computer-Supported Cooperative Work focuses on human-agent teaming and AI agent's roles and effects in modern teamwork. In particular, one understudied key question centers around the construct of team cognition within human-agent teams. This study explores the unique nature of team dynamics in human-agent teams compared to human-human teams and the impact of team composition on perceived team cognition, team performance, and trust. In doing so, a mixed-method approach, including three team composition conditions (all human, human-human-agent, human-agent-agent), completed the team simulation NeoCITIES and completed shared mental model, trust, and perception measures. Results found that human-agent teams are similar to human-only teams in the iterative development of team cognition and the importance of communication to accelerating its development; however, human-agent teams are different in that action-related communication and explicitly shared goals are beneficial to developing team cognition. Additionally, human-agent teams trusted agent teammates less when working with only agents and no other humans, perceived less team cognition with agent teammates than human ones, and had significantly inconsistent levels of team mental model similarity when compared to human-only teams. This study contributes to Computer-Supported Cooperative Work in three significant ways: 1) advancing the existing research on human-agent teaming by shedding light on the relationship between humans and agents operating in collaborative environments, 2) characterizing team cognition development in human-agent teams; and 3) advancing real-world design recommendations that promote human-centered teaming agents and better integrate the two.

The Impact

Изучение влияния учебных курсов по настойчивому поведению подтвердило, что приобретение навыков уверенного поведения приводит к повышению уверенности в себе и самооценки. Была обнаружена положительная статистически значимая корреляция между настойчивыми поведенческими навыками и самооценкой, т.е. чем выше напористость ученика, тем выше его самооценка. Research on the impact of training courses on assertive behavior has shown that the acquisition of assertive behavior skills leads to increased self-confidence and self-esteem. A statistically significant positive correlation was found between persistent behavioral skills and self-esteem, i.e. the higher the student's assertiveness, the higher his self-esteem.
