Light rail development with or without gentrification?: Neighborhood perspectives on changing sense of place in Denver,Colorado

The growing and continued popularity of light rail transit systems in major United States metropolitan areas is leading to growing research on land use impacts, value generation, and contributions to gentrification. While various studies explore the fiscal and environmental influences of light rail transit development in the Denver Metropolitan Area, only recently have scholars turned their attention to gentrification and social influences. This paper analyzes how one station shapes residents' sense of place, providing more nuanced understandings of the role light rail and transit-oriented development affects perceptions of neighborhood character and place attachment. We argue that gentrification can be measured and understood not only quantitatively, but also by how people feel light rail influences their attachment to place. Residents within half a mile of the Evans Light Rail Station were randomly and anonymously surveyed with a series of demographic questions and asked to provide their experiences, observations, and opinions. With 166 household responses, we examine residents' perceptions of Evans Station and sense of place to investigate relationships between factors such as race, age, income, education, length of residency, and walking distance from the light rail station. Analysis of their responses creates a more nuanced understanding of the ways that light rail contributes to positive, neutral, and negative emotions associated with gentrification ranging from appreciation of increased accessibility, younger residents, increased property values, and new commercial development to complaints about increased density, higher rents, traffic, noise, and loss of community.     

Mobility or mobilities: Terrestrial, virtual and aerial categories or entities?

This article attempts to assess the three leading categories of mobility: terrestrial, virtual and aerial, in order to see whether they constitute categories of a single entity of mobility, or alternatively, they constitute three distinct entities of mobility. This exercise is of significance because of the tendency to refer to ‘mobility’ in a rather general sense. Coping with this question, we will, first, put it within a review of relevant concepts and structures. Then, we will elaborate on the distinct features of each of the three mobility categories through their comparison, highlighting mainly differences among them. This will be followed by a presentation of a somehow opposite perspective through the examination of convergences among the three categories of mobility. These two discussions will lead us to view mobility as one single entity consisting of three categories, since all the three categories are IT-based and IT-dependent, and given that they all share a similar model of mobility cycles for both moving people and mobility systems. Using this approach we will compare terrestrial public and personal mobilities, as well as aerial and virtual mobilities, followed by a discussion on implications of a single general mobility model.     

Global air travel: toward concentration or dispersal?

The geography of airline passenger movement through the major cities of the world has changed between 1990 and 2000. The change has been at the expense of the very large global cities and major hubs in favour of a group of next largest cities. It has been detected by comparing the shares of total passenger movement through cities in two separate ways, and by exploring changes in the connectivity between cities over a similar time period. The new pattern reflects the use of new aircraft technology, changes in the location of demand for air travel associated with a broadening in the global linkages between cities, new regulatory arrangements and airline corporate strategies. The implications are that the pressures for airport planning will be felt in a new set of cities, although because the share of passenger traffic through the very large global cities is still high they will remain a major focus for airport planning and management action in the immediate future.     

Third-party remanufacturing mode selection: Outsourcing or authorization?

Many original equipment manufacturers (OEMs) allow third-party remanufacturers (3PRs) to perform remanufacturing operations of branded or patented products – through either outsourcing or authorization. This study compares these two modes by modeling the game between the OEM and the 3PR on equilibrium quantities, prices, and profits. The results suggest that when consumers perceive the remanufactured products with a low value, the 3PR prefers the authorization approach; otherwise the 3PR prefers the outsourcing approach. However, in both scenarios, the OEM obtains higher profit through outsourcing than through authorization. Our further analysis compares two modes’ impacts on consumer surplus, social welfare, and environment.     

Carless in California: Green choice or misery?

Approximately 1 million Californian households do not own a motor vehicle (hereafter a “car”). These households, who are often forgotten in transportation policy discussions, can be organized into two groups based on whether they are voluntarily carless or not. Understanding why some households decide to voluntarily forgo cars could inform policies aiming at reducing our dependency on cars. Understanding the plight of households who are not able to own a car is no less important as these households are at greater risk of social exclusion. Unfortunately, our knowledge of carless households is still sketchy so the purpose of this paper is to start filling this gap. We analyze data from the 2012 California Household Travel Survey using univariate tests and Generalized Structural Equation Models (GSEM) that account for residential self-selection to assess the impacts of various socio-economic and built environment variables on the likelihood to be carless, voluntarily or not. Our results (GSEM Model 1) indicate that carless households are more likely to have less education, a lower income, and a smaller number of members than motorized families. They also tend to live in denser, more land-use diverse, and more walkable areas with better transit coverage. Contrasting voluntarily and involuntarily carless households (GSEM Model 3), we find that involuntarily carless households are less affluent on average and they tend to live in areas that are less land-use diverse, less walkable, and with worse transit coverage. Finally, although residential self-selection is present, its impacts are minor.     

Alternative railway futures: growth and/or specialisation?

Recent centuries have seen a succession of transport technologies, each offering improvements in speed, carrying capacity and/or operational flexibility. Having overcome many physical barriers to freedom of movement, humanity now faces two major, related challenges: dwindling reserves of fossil fuels, and anthropogenic climate change. In these circumstances, rail transport has significant potential advantages over the more energy-intensive modes of road and air.Railways dominated 19th century land transport, peaking in importance in the early 1900s. Market share then declined in the face of competition from road transport and aviation, although rail retained significant passenger and freight transport roles. Major improvements in railway operating efficiency were introduced later in the 20th century, including: the switch from steam to diesel and electric traction; containerisation and focus on long-haul, unit-train freight operations; and the development of high-speed passenger rail services in Japan and Europe, enabling rail to compete successfully with air travel over distances of up to 800 km.The UK Government’s Foresight Programme commissioned a report entitled Intelligent Infrastructure Futures, for which four scenarios were developed of how society might be in 2055. These scenarios are: ‘Perpetual Motion’, ‘Urban Colonies’, ‘Tribal Trading’ and ‘Good Intentions’, each having its own implications for the future of transport. This paper considers the implications of each scenario, and of the underlying/overriding issues of peak oil and climate change, for the possible role and significance of rail transport in meeting our transport needs in the mid-21st century and beyond.     

Forecasting upon a star: Forecasting or wishful thinking?

The purpose of this paper was to perform a detailed analysis of the challenges faced while developing and using econometric models to forecast future transportation demand. To this end, a comparative analysis of the state of practice and state of the art was undertaken on a concrete example – Viracopos Airport in Brazil. A review of relevant technical and scientific literature identified a number of approaches and each representative example was synthesized into a specification “template”. We then compared the performance of each “template” with the observed demand, through an intra-series forecast. A general finding was that econometric model specifications proved to be somewhat homogenous and simpler in nature, with results indicating a relatively small difference in fit and forecast capability across models. Even with the elimination of what is typically considered the main culprit for deviations – the forecast uncertainty of the explanatory (input) variables – the forecast is still subject to sizeable deviation. To address this issue, we proposed developing some sanity check indexes, particularly relevant for long-term forecasts. We conclude that the challenges faced at the Viracopos Airport Concession were far from econometric ones, that the success of the demand forecast and the concession itself required more than a well estimated econometric model. Finally, regarding investment obligations within the concession agreement, we strongly recommend making them conditional to meeting demand milestones, given the inherent unpredictability in forecasts.     

Pets at ecotourism destinations: cute mascot or trojan horse?

Alien species are threatening native fauna worldwide and cats and dogs have well-documented deleterious impacts on wildlife. Ecotourism operators often live and raise their pets in natural reserves. Here we discuss how pets add to the list of potential negative impacts of ecotourism and provide recommendations to control or attenuate such impacts.     

Congestion pricing's conditional promise: promotion of accessibility or mobility?

The derived nature of transportation demand implies that enhancement of mobility per se is not a reasonable goal for transportation policy; instead, improved mobility is desired to the extent that it furthers accessibility—a goal that can be achieved through a variety of measures. The paper uses the mobility–accessibility distinction to distinguish different implementations of congestion pricing. A mobility-based congestion pricing promises to alleviate congestion but threatens to deteriorate from overall regional accessibility as it accelerates metropolitan deconcentration. In contrast, accessibility-based congestion pricing avoids acceleration of sprawl by incorporating policies to ensure that drivers tolled off roads are replaced with residents and travelers arriving at previously congested areas by other means.     

Managing the Cedars of Lebanon: Botanical Gardens or Living Forests?

Lebanon receives about 750,000 visitors a year, attracted by a diverse tourism portfolio with an increasing emphasis on cultural and ecotourism. It was once covered in cedar forest, with the great trees still acting both as metaphor and brand for the country. Today, there are several areas where cedars may still be seen, the most important being the Chouf Reserve, in the Jabal el Barouk mountains near the Bekaa valley, and the famous cedars of the Quadisha valley in north Lebanon (a World Heritage Site since 1998), near the town of Becharre, the centre of Lebanon's ski industry. This paper examines the management of the isolated grove of giant cedar trees at Becharre which has become a sterile botanical garden, and compares it with the living forests of the Chouf Cedar Reserve. The fundamental question being asked here is whether or not World Heritage designation of this natural resource has had conservation benefits, and if such benefits outweigh diminished experience quality for visitors.     

Economic crisis and tourism competitiveness in Spain: permanent effects or transitory shocks?

This paper considers the influence of business cycles and economic crises on Spain's tourism competitiveness. This competitiveness is measured by its share in world tourism. Analysing the presence of unit roots in the market share series from 1958 to 2010, the permanent effects of economic crises on competitiveness are evaluated. The evidence from standard linear unit root tests indicates that crises on Spanish market shares are highly persistent. When we account for endogenously determined structural breaks, we obtain greater support for stationarity, but breakpoints are identified with major economic crises. Therefore the main conclusion obtained is that the effects of the economic shocks are not neutral on competitiveness, with the negative effects being more persistent in highly intensive crises. These crises reinforce a natural downward trend of the Spanish world tourism market share caused by the natural emergence of new competing destinations and by the maturity of the Spain's principal tourism product.     

Competition or complementarity in Dutch inland port development: A case of overproximity?

The port economics literature is extensive, but does not address well the economic effects of inland ports development. This paper explores the extent to which spatial proximity of inland ports vis-a-vis each other influences agglomeration externalities. Spatially lagged regression models are employed to analyse whether spatial dependence between proximate inland ports can be observed or, alternatively, whether the density of the inland port network in the Netherlands is leading to diseconomies of scale because of overproximity. The conclusions indicate that especially in the context of the dense fluvial network of the Netherlands inland ports development involves much competition among inland ports; being proximite to strong neighbouring inland ports is not necessarily beneficial to the growth prospects of an inland port. This indication of overproximity highlights a need for reflection on the possibility of an integrated and coordinated regional governance approach towards inland port development in the Netherlands and North-West Europe. The relationship between inland ports and regional development is obviously present, but ambiguous since it involves a multiplicity of interactions among a diversity of actors.     

Industry convergence in rural tourism development: a China-featured term or a new initiative?

ABSTRACT

Industry convergence is a popular term that has been widely referenced in the context of rural tourism development in China. All levels of government (local, regional, national) in China have repeatedly addressed the significance of industry convergence in their tourism plans and related policies. Despite its popularity, limited studies at present have explored this concept in-depth. Using Huai’an as a case, this study applied a path analysis and reported the industry convergence process in a destination. The findings of this study can provide both theoretical and practical implications that are useful for tourism planners and policy makers.     

Enhancing equitable service level: Which can address better,dockless or dock-based Bikeshare systems?

Dockless bikeshare systems show potential for replacing traditional dock-based systems, primarily by offering greater flexibility for bike returns. However, many cities in the US currently regulate the maximum number of bikes a dockless system can deploy due to bicycle management issues. Despite inventory management challenges, dockless systems offer two main advantages over dock-based systems: a lower (sometimes zero) membership fee, and being free-range (or, at least free-range within designated service areas). Moreover, these two advantages may help to solve existing access barriers for disadvantaged populations. To date, much of the research on micro-mobility options has focused on addressing equity issues in dock-based systems. We have limited knowledge of the extent to which dockless systems can help mitigate barriers to bikeshare for disadvantaged populations. Using San Francisco as a case study, because the city has both dock-based and dockless systems running concurrently, we quantify bikeshare service levels for communities of concern (CoCs) by analyzing the spatial distribution of service areas, available bikes and bike idle times, trip data, and rebalancing among dock-based and dockless systems. We find that dockless systems can provide greater availability of bikes for CoCs than for other communities, attracting more trip demand in these communities because of a larger service area and frequent bike rebalancing practices. More importantly, we notice that the existence of electric bikes helps mitigate the bikeshare usage gap between CoCs and other tracts. Our results provide policy insights to local municipalities on how to properly regulate dockless bikeshare systems to improve equity.     

Community Based Tourism in Namibia: ‘Reality Show’ or ‘Window Dressing’?

Since the 1970s, the African continent has experienced exponential growth in tourism, where growth in numbers of visitors has not necessarily meant economic, social or environmental benefits for the host community. A review of the literature concerning tourism development and its effects on local communities forms the basis for the investigation of the reasons behind community based tourism (CBT) being identified as a tool for development in Namibia. An assessment of the planning and implementation phases of the CBT strategy enables consideration on the role played by international and national governments and non-governmental organisations (NGOs) in laying down policies and providing proactive support for CBT related projects. This paper presents the results of an ongoing empirical research conducted since 2003 in the Kunene region of Namibia, which is an important part of the overall Namibian tourism destination, with world-renowned resources such as Etosha National Park, the Himba culture, Epupa Falls, the desert-adapted elephant and the rhino, to name just a few. By attempting an overall assessment of the Namibian current CBT situation, a set of considerations are offered with regard to its practicalities and in terms of benefits, problems and future outlooks for this sector.     

物流:行业?产业?

目前国内外物流正在迅速发展,但在我国的产业目录中却没有列入物流这个产业,国家预算及税务规划、国家产业投资、建设与发展规划的编制、政府机构的设置及部门和行业管理权限的划分、产业发展政策的制定、产业法制建设等等都与物流产业无关;国家统计局的官方统计口径也从来不把物流作为一个产业来对待,从国家到地方,再到企业,找不到关于物流的完整统计资料,国家、企业和社会都没有办法计算物流成本。那么,物流究竟算不算一个产业?     

The built environment,travel attitude,and travel behavior: Residential self-selection or residential determination?

In examining the impacts of the built environment on travel behavior, studies focused on residential self-selection mostly assume that people self-select residential built environment based on their travel preferences. However, the residential self-selection hypothesis is challenged for a number of reasons including the arguments that that at least in some societies a large percentage of people do not have the privilege to self-select their residence and the built environment may have a significant influence on a person's travel attitude. To shed some light on this debate, this paper makes use of data from a household activity-diary survey conducted in Beijing, China, in 2011–2012 to examine both the hypothesis of residential self-selection and that of residential environment determination. We adopt the natural experimental approach and divide the sample into two groups based on whether or not the respondents had much freedom in regard to choosing where to live: one with the possibility of self-selection and the other one without this possibility. We found reciprocal influences between residential built environment and travel attitude/preference for the first group and influence of residential built environment on travel preferences for the second group. We argue that the complex relationships between the built environment, travel attitude, and travel behavior are featured by both residential self-selection and residential determination. Failing to acknowledge the effects of the built environment on travel attitude may lead to the overestimation of the influence of residential self-selection on the link between the built environment and travel behavior and underestimation of the influence of the built environment on travel behavior.     

Airline type and tourist expenditure: Are full service and low cost carriers converging or diverging?

Since some years ago low-cost carriers (LCCs) are becoming less and less low-cost-like, as well as full-service airlines are becoming less and less full-service-like, thus contributing to lessen the differences between users of one airline type and the other. LCCs have made air travel available to all budgets and enabled tourists to spend more at destination by reallocating their trip expenditure. The objective of this article is to observe if airline types have been converging regarding travellers’ expenditure allocation and total trip expenditure. We use repeated cross sections of the Spanish tourist expenditure survey between 2006 and 2014, and compositional data analysis with a total in order not to confound effects involving expenditure allocation with those involving expenditure volume. Results show that users of both airline types converge in their allocation of the trip budget (between transportation and at-destination expenses, and within at-destination expenses), but diverge with regard to total trip expenditure.     

Dive Tourism and Local Communities: Active Participation or Subject to Impacts? Case Studies from Malaysia

Dive tourism impacts were examined in three Malaysian islands: Perhentian (backpackers), Redang (package tourism) and Mabul (upmarket dive tourism). Qualitative local participation approaches were applied to investigate whether host communities were merely reactive to dive tourism's impacts. Dive tourism affected many aspects of community life. Besides physical/ environmental impacts (new infrastructure), research found varied economic impacts including employment/business opportunities and differing economic linkages. Participation varied between locations, and obstacles to increased participation were revealed. Mainly negative socio‐cultural impacts were observed with minimal participation in cultural productions (handicrafts, performances). However, positive educational impacts emerged, especially environmental awareness and English language acquisition. Copyright © 2012 John Wiley & Sons, Ltd.
