Robots,men and sex tourism

In 2050, Amsterdam's red light district will all be about android prostitutes who are clean of sexual transmitted infections (STIs), not smuggled in from Eastern Europe and forced into slavery, the city council will have direct control over android sex workers controlling prices, hours of operations and sexual services. This paper presents a futuristic scenario about sex tourism, discusses the drivers of change and the implications for the future. The paper pushes plausibility to the limit as boundaries of science fiction and fact become blurred in the ever increasing world of technology, consumption and humanity, a paradigm known as liminality.     

More bang for the buck: Getting the most from accident investigations

An Incident Investigation system based on a combination of Fault Tree Analysis logic and the Deming Principles of Systems and Quality was developed during a three-year period. The system was given an excellent test in the investigation of the explosion of a tank car filled with methacrylic acid. In this case, the Event Tree constructed during the investigation was easily converted into a Fault Tree. The Fault Tree so constructed was then used to evaluate the effectiveness of proposed corrective changes to the production, loading, and analytical systems before the changes were actually implemented. By making use of these tools to guide the addition of feedback loops (“And” Gates in fault Tree terminology), the intrinsic safety of the methacrylic acid production and shipping system was greatly enhanced at a relatively low cost.     

Economic development lessons from and for North American Indian economies*

This paper reviews the literature on economic development as it relates to indigenous people in the United States and Canada, and focuses on how institutions affect economic development of reservation and reserve economies. Evidence shows that strong property rights to reservation and reserve land and natural resources, whether communal or individual, are and always have been important determinants of productivity. Political and legal institutions that are perceived as stable and predictable to tribal members and to non‐Natives also improve economic opportunities for indigenous people living on reservations and reserves. Research reviewed here also shows that culture and acculturation are important in the development process. Although our emphasis is on North America, the findings are applicable to indigenous people in other parts of the world and shed light on growth questions that loom large for developing countries around the world.     

ON PASLNETTI'S ‘G’ MATRIX

Pasinetti's vertically integrated H matrix has been much used in economic theory but his other vertically integrated matrix, G — which is of a quite different nature — has been little noticed. This paper considers the nature of the G matrix, its relationship to H, and varous issues — concerning consumption and growth, value added, sales revenue and differential growth or profit rates — for the analysis of which G is a very useful analytical tool.     

The challenge of articulating human rights at an LGBT ‘mega-event’: a personal reflection on Sao Paulo Pride 2017

Abstract

This paper brings together Critical Event Studies (CES) and a reflexive/narrative autoethnographic approach in order to stimulate a debate around the commodification of public space, and the management of mega-events of dissent. This is achieved using the example of the researcher’s participation in the 2017 Sao Paulo Pride. Sao Paulo Pride is one of the largest LGBT demonstrations in the world. However, corporate interests in the event have commodified dissent in order to commercialise ‘otherness’, and the city has absorbed the demonstration into its cultural offer as a global brand. The confluence of these factors produces a pattern of place dressing and erasure that depoliticise the event and undermines its capacity to effectively articulate human rights. Currently Brazil has some of the most liberal LGBT laws of any South American state, yet recently Lesbian, Gay, Bisexual and Transgender (LGBT)/Sexual Orientation and Gender Identity (SOGI) human rights have been threatened by a rapid rise in hate crime and the emergence of an evangelical Christian right in state and regional assemblies. Within such a context the need to revive the roots of Pride as an articulation of otherness that demands recognition, and as a robust defence of human rights for the LGBT/SOGI community, is more pressing than ever.     

The impact of seasonality on tourism and hospitality operations in the alpine region of New South Wales,Australia

Despite the recognized importance of seasonality for tourism businesses, there has been a distinct lack of studies undertaken in the past that discuss the impact of seasonality on alpine accommodation resorts, and more specifically that focus on an Australian location. The main purpose of this study was to examine whether or not the Australian alpine accommodation providers and ski operations have been significantly impacted by the issue of seasonality and to determine more specifically, had there been industry pressure placed on them to become all season operations? For this study, a total of 15 semi-structured interviews were conducted with managers of hospitality businesses located in the sub-alpine region of Jindabyne, and nearby alpine areas of Perisher and Thredbo in New South Wales, Australia. Study results indicated that the majority of managers acknowledged the fact that there has been an increase in the number of summer visitors each year which has pressured them to make changes to their operations. They conceded that such activity has served to reinforce a ‘stand alone’ mindset which was still prevalent amongst the majority of the managers in the region.
