    A Survey on Socially Aware Robot Navigation: Taxonomy and Future Challenges

    Get PDF
    Socially aware robot navigation is gaining popularity with the increase in delivery and assistive robots. The research is further fueled by a need for socially aware navigation skills in autonomous vehicles to move safely and appropriately in spaces shared with humans. Although most of these are ground robots, drones are also entering the field. In this paper, we present a literature survey of the works on socially aware robot navigation in the past 10 years. We propose four different faceted taxonomies to navigate the literature and examine the field from four different perspectives. Through the taxonomic review, we discuss the current research directions and the extending scope of applications in various domains. Further, we put forward a list of current research opportunities and present a discussion on possible future challenges that are likely to emerge in the field

    Building the New American Man: The Role of the United States Navy in Creating Ideas of Manhood, Masculinity, and an American Identity in the Early American Republic

    After the Revolutionary War, the United States struggled to be recognized by the various global powers throughout the Atlantic World. The American propensity for claiming a neutral trade status, often led to conflict with other nations who were warring with one another. Particularly during their early years, the United States was challenged by Great Britain, the French, and the Barbary powers in the Mediterranean. Relying heavily on maritime trade and contracts, the United States needed to prove that, even without Britain backing them, they were a country worthy of these contracts and treaties. Presented as a social history of the United States Navy, this dissertation argues that it was the U.S. Navy that made these trade agreements possible by being the face and brand of America. Their actions and attitudes not only showed that the United States was a country with morals, humility, and honor, they were also not a country to be trifled with. Taking on the most powerful navies and authorities in the Atlantic and Mediterranean worlds, and not just surviving, but thriving, proved to the world that the United States deserved a place in the trade community. In addition, the U.S. Navy also provided an example of what the new American man was striving to become back home. Gentlemen of courage, honor, intrepidity, integrity, and bravery. Their actions gave the American populace a focus on which to unite, when so many topics threatened to tear them apart. The United States Navy, oft underrepresented in the annals of American History, were actually very important to understanding how and why the United States was given a place on the world stage, and the kind of image they were portraying to the world

    Northern promise: North Queensland and the politics of northern development, from 1939 to 1969

    Get PDF
    Patrick White studied the political history of northern development in Australia. With a focus on north Queensland’s local governments, this research revealed discord between local and national visions of northern development. The thesis demonstrated how local councils influenced federal policy and development in the Australian tropics between 1939 and 1969

    Measuring knowledge sharing processes through social network analysis within construction organisations

    Get PDF
    The construction industry is a knowledge intensive and information dependent industry. Organisations risk losing valuable knowledge, when the employees leave them. Therefore, construction organisations need to nurture opportunities to disseminate knowledge through strengthening knowledge-sharing networks. This study aimed at evaluating the formal and informal knowledge sharing methods in social networks within Australian construction organisations and identifying how knowledge sharing could be improved. Data were collected from two estimating teams in two case studies. The collected data through semi-structured interviews were analysed using UCINET, a Social Network Analysis (SNA) tool, and SNA measures. The findings revealed that one case study consisted of influencers, while the other demonstrated an optimal knowledge sharing structure in both formal and informal knowledge sharing methods. Social networks could vary based on the organisation as well as the individuals’ behaviour. Identifying networks with specific issues and taking steps to strengthen networks will enable to achieve optimum knowledge sharing processes. This research offers knowledge sharing good practices for construction organisations to optimise their knowledge sharing processes

    Assuming Data Integrity and Empirical Evidence to The Contrary

    Get PDF
    Background: Not all respondents to surveys apply their minds or understand the posed questions, and as such provide answers which lack coherence, and this threatens the integrity of the research. Casual inspection and limited research of the 10-item Big Five Inventory (BFI-10), included in the dataset of the World Values Survey (WVS), suggested that random responses may be common. Objective: To specify the percentage of cases in the BRI-10 which include incoherent or contradictory responses and to test the extent to which the removal of these cases will improve the quality of the dataset. Method: The WVS data on the BFI-10, measuring the Big Five Personality (B5P), in South Africa (N=3 531), was used. Incoherent or contradictory responses were removed. Then the cases from the cleaned-up dataset were analysed for their theoretical validity. Results: Only 1 612 (45.7%) cases were identified as not including incoherent or contradictory responses. The cleaned-up data did not mirror the B5P- structure, as was envisaged. The test for common method bias was negative. Conclusion: In most cases the responses were incoherent. Cleaning up the data did not improve the psychometric properties of the BFI-10. This raises concerns about the quality of the WVS data, the BFI-10, and the universality of B5P-theory. Given these results, it would be unwise to use the BFI-10 in South Africa. Researchers are alerted to do a proper assessment of the psychometric properties of instruments before they use it, particularly in a cross-cultural setting
