Tourism administration in the USA
Abstract The attitudes of US federal level administration to tourism in the USA over the past 20 years are discussed in relation to the background and signing into law of the 1981 National Tourism Policy Act, the first major piece of US tourism federal legislation since the 1961 International Travel Act. Focus is on the interplay between the Administration, Legislature and the private sector which led to the development of the Act. After a period of uncertainty the Act appeared to reaffirm federal support for tourism by raising it to Under Secretary level responsibility in the Department of Commerce and by establishing a new agency, the US Travel and Tourism Administration. However, since then the Administration has appeared to back-pedal by authorizing only a small budget and low staffing levels at the USTTA.
Managing Aboriginal Tourism in Hainan, China: Government Perspectives
Abstract Aboriginal tourism is a developing industry with both national and local implications. This paper provides an overview of the relationship between the state and aboriginal tourism by comparing five dichotomous measures. The types of governmental involvement in tourism are categorised from three perspectives: national, provincial and local. The investigation was undertaken in Hainan Island, China where aboriginal tourism among the Li people has become an important source of economic development. The findings suggest that although governments act as coordinators, planners and regulators in tourism development, tensions are raised when governments at different levels seek to ‘authenticate’ aboriginal culture and transform cultural experiences into a tourism product to be bought and sold. It is concluded that future aboriginal tourism planning should focus upon the issue of aboriginal control of tourism, cultural preservation and participation indecision-making processes.
Properties of a monopivot centrifugal blood pump manufactured by 3D printing
An impeller the same geometry as the impeller of a commercial monopivot cardiopulmonary bypass pump was manufactured using 3D printing. The 3D-printed impeller was integrated into the pump casing of the commercially available pump to form a 3D-printed pump model. The surface roughness of the impeller, the hydraulic performance, the axial displacement of the rotating impeller, and the hemolytic properties of the 3D-printed model were measured and compared with those of the commercially available model. Although the surface roughness of the 3D-printed model was significantly larger than that of the commercially available model, the hydraulic performance of the two models almost coincided. The hemolysis level of the 3D-printed model roughly coincided with that of the commercially available model under low-pressure head conditions, but increased greatly under high-pressure head conditions, as a result of the narrow gap between the rotating impeller and the pump casing. The gap became narrow under high-pressure head conditions, because the axial thrust applied to the impeller increased with increasing impeller rotational speed. Moreover, the axial displacement of the rotating impeller was twice that of the commercially available model, confirming that the elastic deformation of the 3D-printed impeller was larger than that of the commercially available impeller. These results suggest that trial models manufactured by 3D printing can reproduce the hydraulic performance of the commercial product. However, both the surface roughness and the deformation of the trial models must be considered to precisely evaluate the hemolytic properties of the model.
