The hierarchy of roads, the locality of traffic, and governance

This study investigates the use of road networks both within and outside of home jurisdictions (city (or town) and county of residence) by analyzing GPS data collected in the Minneapolis—Saint Paul metropolitan area. The study tracked volunteers' travel behavior to determine which roads (and thus which class of roads) users chose to accommodate their travel needs. More than half of the travel on county roads and city streets occur outside of one's home city, but most travel is within one's home county. The average share of travel distance in the home county is more than 70% for both county and city streets. The high share, which does not account for non-residents destined for the county to work or shop, e.g., implies that the free rider problem on city and county streets at the county level is minimal. Of particular concern is travel on city roads in cities other than one's own. To the extent that this is to go to a destination in that city, that travel is also local. However, because city and county roads are typically funded by those jurisdictions from land-based sources such as property taxes, through trips with neither end in the city through which they are traveling are in a very real sense “free riders”, and pose a problem. With growing trip lengths and emerging economies of scale in road management, it may be appropriate to consider moving more roads from township, town, or city level to the county level of government.     

Tourism,changing architectural styles,and the production of place in Itacaré, Bahia,Brazil

This article examines changing architecture in Itacaré, Brazil, as it transitions from a fishing village to an international tourist destination. Tourism, as an assemblage of practices and perspectives, recreates places in specific ways that structure social and environmental relationships. Through an examination of historical architectural styles, tourist architecture, and popular architecture in Itacaré, this article analyses the ways a tourist economy has physically and socially rebuilt the city. Socially, the changing architecture marks and creates differences between class, racial, and regional identities while also providing an idiom through which public conversations about these changing economic systems and demographics are articulated. At the same time, the expansion of the city has led to racial-, regional-, and class-based segregation. Environmentally, tourist architecture creates new relationships to nature through re-imagining Itacaré’s position in relation to other rural and urban places and a new emphasis on the aesthetic value of nature.     

Reviewing the DATAS of aviation research data: Diversity,availability, tractability,applicability, and sources

The field of aviation research is entering the era of big data. While data-driven advancements in aviation have clearly brought about applicable models and results with immediate implications, we argue that the influx of aviation data should be better characterized and documented to enable more efficient and standardized usage. To this end, we examine 200 well-cited research articles from sub-disciplines ranging from revenue management to air traffic control published on or after 2010 in order to analyze the diversity, availability, tractability, applicability, and sources (DATAS) of data utilized in aviation research. We find high levels of data diversity within aviation research, with 16 data categories ranging from air traffic flow management-type data to data from distributed sensors in line with the Internet-of-Things (IoT) paradigm. We identified a dominance of proprietary, non-public data in aviation research, with 68% of the 200 research articles utilizing solely proprietary data in deriving their results, and a further 8% utilizing a mixture of proprietary and publicly available data. The pervasiveness of proprietary data has implications on reproducibility and extending research results. We also highlight the increasing tractability of the data by surveying the computational power required to process the data sets, and present vignettes of applications and results that stem from these data-driven studies. Finally, we propose several recommendations regarding standardizing data source nomenclature as well as increasing the availability of and usage of publicly available data.

Incarcerating Travels: Travel Stories,Tourist Orders,and the Politics of the 'Hawai'ian Paradise'

This article explores how travel practices are structured and harnessed to politics. While travel practices operate through claims of innocence, curiosity and adventure, they are deeply political practices that participate in projects and programmes ranging from statecraft to appropriation of peoples and places in the service of global finanscapes. In Michel de Certeau's words, travelling in economies of desire, travel practices partake in the 'production of specific politico-cultural orders' in travel spaces that often articulate narrow horizons in identity, ethnicity, nation, participation and governmentality. In worst cases, travel practices are instrumental in the production of orders that create and simultaneously hide the alterity of peoples and their places. This article reflects on the politics of travel that escapes notice or is concealed in travel discourses and representations in Hawai'i. More specifically, it examines how travel acts participate in the production of (1) a politico-cultural order in Hawai'i that creates and hides the alterity of Hawai'i's indigenous peoples, (2) a plural nation-story of the United States that operates through the interstices of the tourist orders and (3) a capital story that enlists both indigenous resources and predominant political powers to excavate profits.     

The good,the bad,and the ugly: 30 years of US airline deregulation

The US airline industry was deregulated in 1978 and has undergone significant changes in industry structure, profitability, employment, passenger volume, and patterns of service and fares, among other characteristics. This paper sets out to make three contributions to the literature as related to the story of airline deregulation. First, discussion of economic theory will provide the context for an updated overview of the positive, negative, and really negative results of US airline deregulation, summarized in the form of “the good”, “the bad”, and “the ugly”. Second, this paper provides a periodization of the 30-year history of US airline deregulation that is important in understanding the cycles of change as reflected in the industry’s financial performance and other relevant data. Third, this paper contributes to the renewed debate about the efficacy of deregulation and liberalization policies, particularly at a time when the global financial crisis has cast a harsh spotlight on the (un)desirability of these policies. Some of the good results during the 30 years of airline deregulation, from the industry and consumer perspective, include higher passenger volumes, more service to the most popular destinations, and lower fares on average. Bad results include financial and employment instability, diminution in the quality of airline service overall, and fewer flights and higher fares to smaller places. The recent 2000–2005 period has been particularly ugly, as the airline industry has lost over $30 billion, and several high-profile carriers, such as United, Delta, Northwest, and US Airways, were forced into bankruptcy.

Museums,exhibits and visitor satisfaction: a study of the Cham Museum,Danang, Vietnam

Museums have several functions as custodians of heritage and culture, disseminators of knowledge about heritage and as places that attract tourists as well as local residents. Arguably all these functions require visitors to be satisfied with the visit experience if museums are to achieve their objectives. This paper reports findings from 411 visitors to the Cham Museum, Danang, Vietnam. It describes the nature of the museum and argues that satisfaction involves the conative, which may be measured by the willingness of visitors to make recommendations to others. However, the study identifies that interpretation and displays are important determinants and simply adjuncts to the generation of satisfaction.
