    Autonomous robots acting as companions or assistants in real social environments should be able to sustain and operate over an extended period of time. Generally, autonomous mobile robots draw power from batteries to operate various sensors, actuators and perform tasks. Batteries have a limited power life and take a long time to recharge via a power source, which may impede human-robot interaction and task performance. Thus, it is important for social robots to manage their energy, this paper discusses an approach to manage power resources on mobile robot with regard to social aspects for creating life-like autonomous social robots

    Prosodic transcription of Glasgow English: an evaluation study of GlaToBI

    Get PDF
    GlaToBI, a version of the ToBI prosodic transcription system which can be used to transcribe the intonation patterns of western Scottish (Glasgow) English, is currently under development. An assessment of GlaToBI, similar to the evaluation studies that were undertaken for the original ToBI system [7], and for GToBI, a version developed for German [4], has been carried out to test the new system 's reliability, learnability and comprehensiveness. The results of this study show that this adaptation of the ToBI system can be applied with the expected level of reliability to the transcription of Glasgow English. 1. INTRODUCTION Very little corpus based work has been done on the prosodic features of English dialects other than Standard American and southern British (Received Pronunciation). However, with the creation of databases such as the University of Edinburgh's HCRC Map Task corpus [1], the predominant dialect of which is western Scottish (Glasgow) English, the opportunity has arisen..

    How Can a Robot Signal Its Incapability to Perform a Certain Task to Humans in an Acceptable Manner?

    In this paper, a robot that is using politeness to overcome its incapability to serve is presented. The mobile robot “Alex” is interacting with human office colleagues in their environment and delivers messages, phone calls, and companionship. The robot's battery capacity is not sufficient to survive a full working day. Thus, the robot needs to recharge during the day. By doing so it is unavailable for tasks that involve movement. The study presented in this paper supports the idea that an incapability of fullfiling an appointed task can be overcome by politeness and showing appropriate behaviour. The results, reveal that, even the simple adjustment of spoken utterances towards a more polite phrasing can change the human's perception of the robot companion. This change in the perception can be made visible by analysing the human's behaviour towards the robot

    Influencers of Succession Planning Among Rural Community College Chief Executives

    Get PDF
    The challenge of maintaining strong leadership within many community colleges has been exacerbated by many factors including demographic shifts, therefore, succession planning is one tool used by institutions to offset the challenge of dealing with aging leaders, retirements, and a limited pool of competent applicants. Many senior administrators have and will continue to retire at rapid rates and fewer well-prepared individuals seem to be available or willing to move into these roles. Higher education literature has explored the future of community colleges during this time of change, some examining critical factors for the future of community colleges by asking questions such as: Who will the next leaders be? Will they be committed to the community colleges’ historic mission of ensuring access? How will they be prepared to meet current and future challenges? This case study was designed to explore the influencers of succession planning and how rural community college leaders identify and develop future leaders. As part of this exploration, the study examined institutional culture and community stakeholders as influencers. Six presidents or chancellors from rural community colleges were chosen for face-to-face interviews using purposive sampling to gain an in-depth understanding of the ways current community college leaders are developing the pipeline of future leaders. Through qualitative analysis three themes emerged: adaptation and flexibility are primary characteristics needed by future leaders; organizational leadership is influenced by organizational culture and community needs; and leadership development must include broad organizational exposure. Recommendations stemming from this study are that presidents and chancellors from other states, geographical locations, or urban areas may have different perspectives regarding leadership selection and development. Replication of this study in other states, urban institutions, and institutions with different budget levels would allow comparisons of the findings to further the research on this topic. Additional research also might examine individuals who have been identified as potential leaders and may reveal how future leaders are preparing for leadership opportunities

    Interactive drama in real and virtual worlds.

    Get PDF
    How do we resolve the paradox of computer-supported interactive drama - that the human participant requires the very freedom to interact that the authored narrative structure denies them? This paper reports work around the concept of Emergent Narrative - the development of narrative structure through interaction itself. We cover both systems using a virtual world and those using a virtually-augmented real world, exploring how far reworking narrative structure as a loop between the causal (plot) and affective (character) can produce engaging experiences for participants. We discuss the key role of a cognitive-affective architecture for charac-ters and the process of cognitive appraisal as an engine for both in-character and in-role dramatic action

    Chapter 9 Relational Agency and the Local Governance of Climate Change

    Get PDF
    Drawing upon a variety of empirical and theoretical perspectives, The Urban Climate Challenge provides a hands-on perspective about the political and technical challenges now facing cities and transnational urban networks in the global climate regime. Bringing together experts working in the fields of global environmental governance, urban sustainability and climate change, this volume explores the ways in which cities, transnational urban networks and global policy institutions are repositioning themselves in relation to this changing global policy environment. Focusing on both Northern and Southern experience across the globe, three questions that have strong bearing on the ways in which we understand and assess the changing relationship between cities and global climate system are examined. The Urban Climate Challenge will be of interest to scholars of urban climate policy, global environmental governance and climate change. It will be of interest to readers more generally interested in the ways in which cities are now addressing the inter-related challenges of sustainable urban growth and global climate change.

    The interaction between voice and appearance in the embodiment of a robot tutor

    Get PDF
    Robot embodiment is, by its very nature, holistic and understanding how various aspects contribute to the user perception of the robot is non-trivial. A study is presented here that investigates whether there is an interaction effect between voice and other aspects of embodiment, such as movement and appearance, in a pedagogical setting. An on-line study was distributed to children aged 11–17 that uses a modified Godspeed questionnaire. We show an interaction effect between the robot embodiment and voice in terms of perceived lifelikeness of the robot. Politeness is a key strategy used in learning and teaching, and here an effect is also observed for perceived politeness. Interestingly, participants’ overall preference was for embodiment combinations that are deemed polite and more like a teacher, but are not necessarily the most lifelike. From these findings, we are able to inform the design of robotic tutors going forward

    The Cerevoice Blizzard Entry 2007: Are Small Database Errors Worse than Compression Artifacts?

    Get PDF
    In commercial systems the memory footprint of unit selection systems is often a key issue. This is especially true for PDAs and other embedded devices. In this years Blizzard entry CereProc R○gave itself the criteria that the full database system entered would have a smaller memory footprint than either of the two smaller database entries. This was accomplished by applying speex speech compression to the full database entry. In turn a set of small database techniques used to improve the quality of small database systems in last years entry were extended. Finally, for all systems, two quality control methods were applied to the underlying database to improve the lexicon and transcription match to the underlying data. Results suggest that mild audio quality artifacts introduced by lossy compression have almost as much impact on MOS perceived quality as concatenation errors introduced by sparse data in the smaller systems with bulked diphones. Index Terms: speech synthesis, unit selection. 1
