Drivers and barriers to the adoption and diffusion of Sustainable Jet Fuel (SJF) in the U.S. Pacific Northwest

Sustainable Jet Fuel (SJF) represents an important component of the airline industry's strategy to simultaneously reduce GHG emissions while meeting a growing demand for international air travel. SJFs also have the potential to provide fuel supply diversification and security, enhance fuel price stability and provide regional/rural economic development benefits. This paper measures and ranks perceived drivers and barriers to an economically viable SJF industry in a unique U.S. region, the U.S. Pacific Northwest (PNW), through personal interviews with key aviation fuel supply chain stakeholders conducted from June to September 2015. In addition to providing a fertile arena for this first effort to systematically assess these drivers and barriers, the U.S. PNW is unique due to the region's long strategic focus on aviation innovation and its importance to the regional economy, the seminal efforts in the region to outline a path forward on SJF beginning in 2010, and the relatively small population spread over a large geographic area with a limited number of “hub” airport nodes which geographically concentrates aviation fuel demand and distribution. Nineteen stakeholder interviewees acknowledge that, in order for regional SJF adoption-diffusion to occur, airline jet fuel buyers must drive the process, particularly as they deal with greenhouse gas (GHG) emission issues and related policy considerations. Important perceived barriers to SJF industry scale-up in the U.S. PNW include the high production costs of SJF and related issues, such as fuel logistics and quality control in the transport, storage, and blending of SJFs. Perceptions around chain-of-custody issues, such as blending, tracking, and crediting of SJFs and future SJF market share projections for the year 2030 were also examined. Incorporating stakeholder input into discussions about adding blended SJF into the U.S. aviation fuel supply provides needed insight for the biofuels industry, policymakers, and researchers.

Corporate Strategy and NAFTA When Environmental Regulations Are Barriers to Trade

SUMMARY

Under the North American Free Trade Agreement (NAFTA), domestic environmental regulations can have the ultimate impact of erecting entry barriers against foreign companies. These actions by domestic firms are part of a corporate “shelter”-seeking strategy. Five recent cases are analyzed out of twenty-four environmental disputes relevant to NAFTA.     

Constraints to Park Visitation: A Meta-Analysis of North American Studies

The constraints that curb visitation to parks have received considerable research attention and remain an important issue. Constraints to outdoor leisure in parks include structural barriers, such as cost of entry, interpersonal barriers, for example, lack of a partner to visit with, or intrapersonal barriers, including lack of interest. Using a meta-analysis approach, this article integrates the findings of 22 North American studies with 541 estimates, conducted over a 30-year period, to determine the key constraints to park visitation based on various socio-demographic factors. The findings highlight the varying roles that constraints play in limiting the visitation of people according to race, age, gender, education and income. Gaps in the literature are identified, with implications for encouraging visitation for more constrained groups discussed. An agenda for future research is presented.

Electronic Marketing Communications: An Evolving Environment,but Similar Story Regarding the Perception of Unsolicited Commercial E-Mail and Postal Direct Mail

The internet is still a relatively new mass communication tool for advertisers and marketers. When weighing the potential benefits of electronic techniques against the financial investment, spam seems particularly attractive to marketers for either for-profit or non-profit objectives. Since it is unlikely that marketers will decrease their efforts related to spam and postal direct mail as a form of communicating to mass consumers, it is important to track consumer attitudes so that audiences are not subjected to the backlash predicted by psychological reactance. The results of this study found that spam is more irritating than postal direct mail at both T₁ (2004) and T₂ (2006), and participants in T₂ found both direct marketing communication methods more intrusive than those in T₁.
