A number of full service network carriers have recently stated their ambition to develop certain ultra-long-range (ULR) routes, such as Doha to Auckland, Dubai to Auckland, Dubai to Panama City, Singapore to San Francisco, Singapore to New York, all of which require a great circle distance between 7,000–9,000 nautical miles (nm) with an estimated travel time between 15 and 20 hours. This paper examines the capability of the current generation of wide-bodied passenger aircraft to satisfy this evolving strategy, and the impact, if any, on the provision of air cargo transportation. An exploratory study is presented herein based on an assessment of each aircraft type’s payload-range envelope, taken from the appropriate Aircraft Airports Handling Characteristics Manual. The key findings reveal that airlines wishing to pursue this ultra-long-range strategy have a surprisingly limited choice of current-generation passenger aircraft which are capable of flying the desired mission profile without compromising significantly on passenger numbers and cargo payload.

This research focuses on the frequent and persistent problem of truck shortages for time-sensitive, perishable produce shipment out of the Pacific Northwest. Washington State is the number one apple-producing state in the United States, accounting for more than 2.7 million tons of apples per year valued in excess of $1 billion. However, without timely and accessible transportation to move the product from production to the consumer's table, the value to apple producers and the state's economy diminishes rapidly. This research aims to identify and quantify the change in total transportation cost that occurs as a result of seasonal truck shortages and associated rate increases and to provide an avenue for evaluating changes in specific destination markets, modal changes, and market competitiveness. A cost-minimizing optimization model is used to represent apple shipments from 29 producing supply points to 16 domestic markets and three international export markets over four seasons for two modes (truck and rail). Total transportation costs increase nearly $12 million as a result of truck shortages, from $245.6 million without shortages to $257.5 million under the current seasonal situation. Overall (across all seasons), the export markets of Nogales, Arizona; McAllen, Texas; and the Port of Seattle, Washington, are most affected by the truck shortages, followed by domestic markets near Seattle and San Francisco, California. The large markets of New York City, New York, and Los Angeles, California also experience relatively large increases in transportation cost per ton mile.

In the global airline industry, an airline’s fleet routing affects its profitability, level of service and its competitive position. Using a qualitative research approach, this paper examines Singapore Airlines Airbus A350-900XWB fleet deployment and route network development for the period 2016 to 2018. The qualitative data was examined using document analysis. The study found that Singapore Airlines has deployed the Airbus A350-900XWB aircraft on new air routes from Singapore to Cape Town via Johannesburg, Düsseldorf and Stockholm via Moscow and return. The Airbus A350-900XWB aircraft are also replacing older, less efficient aircraft as part of the company’s fleet modernization strategy. Singapore Airlines is also acquiring the new ultra-long-range variant of the Airbus A350-900XWB for use on its proposed new non-stop services from Singapore to Los Angeles and Newark Liberty Airport in New Jersey, USA. The longest flight stage length is the Singapore to San Francisco route which is 7339 nautical miles (13,594 km) in length. The shortest stage length is between Singapore and Kuala Lumpur (160 nautical miles or 297 km). The new non-stop services from Singapore to Los Angeles and New York City will be the longest non-stop services operated by Singapore Airlines. The flight stage lengths between Singapore and Los Angeles and Singapore and Newark Liberty Airport are 7621 nautical miles (14,114 km) and 8285 nautical miles (15,344 km), respectively. The greatest number of available seat kilometers (ASKs) are generated on Singapore Airlines Airbus A350-900 XWB service from Singapore to San Francisco (3.57 million ASKs). The smallest number of ASKs produced are on the short-haul service from Singapore to Kuala Lumpur (75,141 ASKs).

This study aimed to assess the impact of a four-point bonus system on recertification in Leadership in Energy and Environmental Design for Existing Buildings (LEED-EB) 2009 office space projects in four metropolitan cities: Washington, DC, Chicago, New York, and San Francisco. We analyzed 123 paired LEED-EB 2009 projects where each pair (i.e., certification–recertification) was used on the same building. The percentage of average score was used to evaluate differences in certification–recertification strategies: (1) gold-gold with and without the bonus, (2) silver-gold with and without the bonus, and (3) platinum-platinum with the bonus. The replication method was used to evaluate the overall tendency for four metropolitan cities. We found that while LEED-EB 2009 projects used a four-point recertification bonus, achievements in the materials and resources (MR) and indoor environmental quality (EQ) categories declined in each of the four metropolitan cities. We identified this overall tendency at three levels of certification–recertification: gold-gold, silver-gold, and platinum-platinum. We hypothesized that if the use of a four-point recertification bonus in LEED-EB 2009 projects resulted in lower achievements in the MR/EQ categories, then the use of the 10-point recertification bonus in LEED-EB 4.1 projects could lead to a deterioration in the sustainability of existing office buildings.

On June 1, 2008 New York State imposed a new law, called the “Amazon tax”, that requires online retailers who receive more than $10,000 per year in revenue from New York affiliates to collect New York sales tax. While a number of major online retailers have challenged the law in court, it has already had a significant impact on affiliate marketers. If the law is upheld other states will enact similar laws. This paper details the impact of the law on affiliate marketers, online retailers, and affiliate networks. It provides specific short and long range recommendations to each of these types of companies.

For young Australians in the early 1960s America was the icon of pop music and fashion. This was the result of the projection of America through the mass media and the numerous American rock'n'roll acts that were brought to Australia by Lee Gordon, an American entrepreneur who lived in Sydney (Zion 1984). This overall tendency led the American, A. L. McLeod, to observe when writing about Australian culture in 1963 thatin general, Australian popular music is slavishly imitative of United States models; it follows jazz, swing, calypso or whatever the current fashion is in New York or San Francisco at a few months distance. (McLeod 1963, p. 410)Yet by late 1963 the potency of America was in decline. For while the Californian surf music craze made a somewhat delayed impact, especially in Sydney, the popularity of the Beatles was gathering momentum. This can be traced crudely through the Top Forty lists of the day: in Sydney the song ‘From Me To You’ entered the charts on 12 July 1963 and eventually reached number six (Barnes et al. 1979, p. 50).

Abstract The introduction of the Airbus A350-900 (A359) and the Boeing B787-9 (B789) have enabled airlines to operate ultra-long-range services. Using a mixed methods research design, this study has examined the air cargo-carrying potential of Singapore Airlines Airbus A350-900XWB (A359) and United Airlines Boeing B787-9 (789) aircraft on their ultra-long-haul San Francisco to Singapore and the Singapore to San Francisco air routes. The qualitative data was analysed using document analysis, and the air cargo payload was modelled by simulation. The air cargo-carrying potential of the two aircraft types was significantly influenced by enroute weather. In the event of eastbound winds, the Singapore Airlines Airbus A350-900XWB air cargo payload was 16.9 tonnes and the United Airlines Boeing 787-9 was 11.5 tonnes, when these flights had a full passenger payload. In the case of westbound winds with a full passenger payload, the Singapore Airlines Airbus A350-900XWB air cargo payload was 13.1 tonnes and the United Airlines Boeing 787-9 was 7.9 tonnes. When there were no winds on the air routes, the Singapore Airlines Airbus A350-900XWB offered 15.0 tonnes and the United Airline Boeing 787-9 offered 9.7 tonnes of air cargo payload, respectively.

Americans are far more divided than other Westerners over basic issues, including wealth inequality, health care, climate change, evolution, the literal truth of the Bible, apocalyptical prophecies, gender roles, abortion, gay rights, sexual education, gun control, mass incarceration, the death penalty, torture, human rights, and war. The intense polarization of U.S. conservatives and liberals has become a key dimension of American exceptionalism—an idea widely misunderstood as American superiority. It is rather what makes America an exception, for better or worse. While exceptionalism once was largely a source of strength, it may now spell decline, as unique features of U.S. history, politics, law, culture, religion, and race relations foster grave conflicts and injustices. They also shed light on the peculiar ideological evolution of American conservatism, which long predated Trumpism. Anti-intellectualism, conspiracy-mongering, radical anti-governmentalism, and Christian fundamentalism are far more common in America than Europe, Canada, Australia, and New Zealand. Drawing inspiration from Alexis de Tocqueville, Mugambi Jouet explores American exceptionalism’s intriguing roots as a multicultural outsider-insider. Raised in Paris by a French mother and Kenyan father, he then lived throughout America, from the Bible Belt to New York, California, and beyond. His articles have notably been featured in The New Republic, Slate, The San Francisco Chronicle, The Huffington Post, and Le Monde. He teaches at Stanford Law School.
