(2016): Towards assessing the human trajectory planning horizon. In: PLoS one 11 (12)
Abstract: Mobile robots are envisioned to cooperate closely with humans and to integrate seamlessly into a shared environment. For locomotion, these environments resemble traversable areas which are shared between multiple agents like humans and robots. The seamless integration of mobile robots into these environments requires accurate predictions of human locomotion. This work considers optimal control and model predictive control approaches for accurate trajectory prediction and proposes to integrate aspects of human behavior to improve their performance. Recently developed models are not able to reproduce accurately trajectories that result from sudden avoidance maneuvers. Particularly, the human locomotion behavior when handling disturbances from other agents poses a problem. The goal of this work is to investigate whether humans alter their trajectory planning horizon, in order to resolve abruptly emerging collision situations. By modeling humans as model predictive controllers, the influence of the planning horizon is investigated in simulations. Based on these results, an experiment is designed to identify, whether humans initiate a change in their locomotion planning behavior while moving in a complex environment. The results support the hypothesis, that humans employ a shorter planning horizon to avoid collisions that are triggered by unexpected disturbances. Observations presented in this work are expected to further improve the generalizability and accuracy of prediction methods based on dynamic models.

(2013) : It’s not polite to point Generating socially-appropriate deictic behaviors towards people: 2013 8th ACM/IEEE International Conference on Human-Robot Interaction (HRI): Tokyo, Japan: IEEE, S. 267-274
DOI: https://doi.org/10.1109/HRI.2013.6483598 Abstract: Pointing behaviors are used for referring to objects and people in everyday interactions, but the behaviors used for referring to objects are not necessarily polite or socially appropriate for referring to humans. In this study, we confirm that although people would point precisely to an object to indicate where it is, they were hesitant to do so when pointing to another person. We propose a model for generating socially-appropriate deictic behaviors in a robot. The model is based on balancing two factors: understandability and social appropriateness. In an experiment with a robot in a shopping mall, we found that the robot’s deictic behavior was perceived as more polite, more natural, and better overall when using our model, compared with a model considering understandability alone.

(2009): Testing and extending the group engagement model: Linkages between social identity, procedural justice, economic outcomes, and extrarole behavior. In: Journal of Applied Psychology 94 (2), S. 445-464. DOI: 10.1037/a0013935
DOI: http://www.ncbi.nlm.nih.gov/pubmed/19271800 Abstract: Two field studies tested and extended the group engagement model (Tyler & Blader, 2000, Tyler & Blader, 2003) by examining the model with regard to employee extrarole behavior. Consistent with the group engagement model's predictions, results of these studies indicate that the social identities employees form around their work groups and their organizations are strongly related to whether employees engage in extrarole behaviors. Moreover, the studies demonstrated that social identity explains the impact of other factors that have previously been linked to extrarole behavior. In particular, the findings indicate that social identity mediates the effect of procedural justice judgments and economic outcomes on supervisor ratings of extrarole behavior. Overall, these studies provide compelling indication that social identity is an important determinant of behavior within work organizations and provide strong support for the application of the group engagement model in organizational settings.

(2008): All in the Timing. In: Small Group Research 39 (3), S. 328-351. DOI: 10.1177/1046496408317036
Abstract: The role of time in measuring group and team temporality constitutes more than a methodological issue-it is a theoretical question. That is, if group interaction is theorized as processual and processes occur through time, then research on team temporality, as well as a range of other issues, must grapple with the methodological implications of our theories. This article contributes to INGRoup's aim to advance theory and methods for understanding groups by exploring methodological approaches that allow researchers to capture a variety of team processes over time. Three case studies address the practical issues involved with employing various types of time-sensitive data collection, time-dependent coding, and time-based analysis, including their advantages and disadvantages. Together, the authors describe diverse field and analytical methods useful for interrogating theoretical assumptions about time in groups. Doing so expands the notion of group temporality to consider the role of both epochal and fungible times at multiple stages of group research. zitiert von 59

(2008): Value of wireless personal digital assistants for practice: perceptions of advanced practice nurses. In: Journal of clinical nursing 17 (16), S. 2146-2154. DOI: 10.1111/j.1365-2702.2008.02351.x
DOI: http://www.ncbi.nlm.nih.gov/pubmed/18705736 Abstract: AIMS AND OBJECTIVES The aims were to explore advanced practice nurses' perceptions on wireless Personal Digital Assistant technologies, to establish the type and range of tools that would be useful to support their practice and to identify any requirements and limitations that may impact the implementation of wireless Personal Digital Assistants in practice. BACKGROUND The wireless Personal Digital Assistant is becoming established as a hand-held computing tool for healthcare professionals. The reflections of advanced practice nurses' about the value of wireless Personal Digital Assistants and its potential to contribute to improved patient care has not been investigated. DESIGN A qualitative interpretivist design was used to explore advanced practice nurses' perceptions on the value of wireless Personal Digital Assistant technologies to support their practice. METHODS The data were collected using survey questionnaires and individual and focus group interviews with nurse practitioners, clinical nurse specialists and information technology managers based in British Columbia, Canada. An open-coding content analysis was performed using qualitative data analysis software. RESULTS Wireless Personal Digital Assistant's use supports the principles of pervasivity and is a technology rapidly being adopted by advanced practice nurses. Some nurses indicated a reluctance to integrate wireless Personal Digital Assistant technologies into their practices because of the cost and the short technological life cycle of these devices. Many of the barriers which precluded the use of wireless networks within facilities are being removed. Nurses demonstrated a complex understanding of wireless Personal Digital Assistant technologies and gave good rationales for its integration in their practice. CONCLUSIONS Nurses identified improved client care as the major benefit of this technology in practice and the type and range of tools they identified included clinical reference tools such as drug and diagnostic/laboratory reference applications and wireless communications. RELEVANCE TO CLINICAL PRACTICE Nurses in this study support integrating wireless mobile computing technologies into their practice to improve client care.

(2004): Bad but bold. Ambivalent attitudes toward men predict gender inequality in 16 nations. In: Journal of personality and social psychology 86 (5), S. 713-728. DOI: 10.1037/0022-3514.86.5.713
DOI: http://www.ncbi.nlm.nih.gov/pubmed/15161396 Abstract: A 16-nation study involving 8,360 participants revealed that hostile and benevolent attitudes toward men, assessed by the Ambivalence Toward Men Inventory (P. Click & S.T. Fiske, 1999), were (a) reliably measured across cultures, (b) positively correlated (for men and women, within samples and across nations) with each other and with hostile and benevolent sexism toward women (Ambivalent Sexism Inventory, P. Click & S.T. Fiske, 1996), and (c) negatively correlated with gender equality in cross-national comparisons. Stereotype measures indicated that men were viewed as having less positively valenced but more powerful traits than women. The authors argue that hostile as well as benevolent attitudes toward men reflect and support gender inequality by characterizing men as being designed for dominance. zitiert von 387

(1994): Factors affecting satisfaction among community-based hospice volunteer visitors. In: The American journal of hospice & palliative care 11 (4), S. 30-37. DOI: 10.1177/104990919401100411
DOI: http://www.ncbi.nlm.nih.gov/pubmed/7893559 Abstract: Trained volunteers are an essential component in the delivery of care to clients and families facing a terminal and/or life-threatening illness. As the need for hospice care increases, so does the need to increase the number of volunteers available for visiting. Hospice of London, which is a community based hospice, proposed that volunteers who felt satisfied would remain with the organization longer, thereby, decreasing the costs associated with training new volunteers and enhancing the ability of the agency to provide high-quality volunteer client matches. Accordingly, a survey was conducted in August 1992 to determine which factors were related to hospice volunteer satisfaction. One hundred and five volunteer were surveyed over the telephone. Results demonstrated a positive correlation between satisfaction and feeling like a team member, receiving feedback from staff, feeling valuable and having the volunteer's expectations match the position. Differences in the factors related to satisfaction were noted when the groups were divided by age and gender.
