Tourism, trade and domestic welfare

Tourism has been regarded as a major source of economic growth and a source of foreign exchange. It has also been viewed as an activity that imposes costs on the host country. Such costs include increased pollution, congestion and despoliation of fragile environments, and intra-generational inequity aggravation. One aspect that has been ignored is the general equilibrium effects of tourism on other sectors in the economy. This paper presents a model that captures the interdependence between tourism and the rest of the economy, in particular agriculture and manufacturing. An important result obtained is that the tourist boom may 'immiserize' the residents.

Motivations for developing direct trade relationships

Purpose – This study aims to understand buyer and supplier motives for developing direct relationships with their trade partners.

Design/methodology/approach – A total of 18 in-depth interviews were conducted across Victoria and Tasmania (Australia); eight with retail buyers and ten with fresh produce suppliers. Both parties were involved in a direct relationship with their trade partner.

Findings – The research reveals a large variety of motivations that influence buyers and suppliers when deciding whether to operate in a direct or non-direct relationship with their trade partner. Motivations for both parties are remarkably similar, with buyers and suppliers ultimately attempting to minimise the inherent risk associated with operating in a volatile environment.

Research limitations/implications – The study may be limited by the fact that buyers and suppliers of different commodities were included in the study. In addition, the varied nature of the respondents' role may have impacted their judgment. The inability to interview dyads in all cases also limits the research.

Practical implications – This research has implications for both researchers and practitioners already involved in, or considering becoming involved in, a direct trade relationship. Clarification of motivations for bypassing intermediaries shows how both trade partners can minimise external risk and strengthen competitive advantage by assuming a direct relationship.

Originality/value – Extant research within this literary field is largely quantitatively based with researchers focusing on distinct relationship constructs, the definition of relationship marketing and the process of relationship development. In response to these limitations, this research adopted a qualitative approach in examining the core motivations for developing a direct trade relationship within the fresh produce industry.

Genotoxicity assessment of soils from wastewater irrigation areas and bioremediation sites using the Vicia faba root tip micronucleus assay

Genotoxicity potential of soils taken from wastewater irrigation areas and bioremediation sites was assessed using the Vicia faba root tip micronucleus assay. Twenty five soils were tested, of which 8 were uncontaminated soils and taken as the control to examine the influence of soil properties; 6 soils were obtained from paddy rice fields with a history of long-term wastewater irrigation; 6 soils were obtained from bioremediation sites to examine effects of bioremediation; and 5 PAH-contaminated soils were used to examine methodological effects between direct soil exposure and exposure to aqueous soil extracts on micronuclei (MN) frequency () in the V. faba root tips. Results indicate that soil properties had no significant influences on MN frequencies (p > 0.05) when soil pH varied between 3.4 to 7.6 and organic carbon between 0.4% and 18.6%. The MN frequency measured in these control soils ranged from 1.6‰ to 5.8‰. MN frequencies in soils from wastewater irrigation areas showed 2- to 48-fold increase as compared with the control. Soils from bioremediation sites showed a mixed picture: MN frequencies in some soils decreased after bioremediation, possibly due to detoxification; whereas in other cases remediated soils induced higher MN frequencies, suggesting that genotoxic substances might be produced during bioremediation. Exposure to aqueous soil extracts gave a higher MN frequency than direct exposure in 3 soils. However, the opposite was observed in the other two soils, suggesting that both exposure routes should be tested in case of negative results from one route. Data obtained from this study indicate that the MN assay is a sensitive assay suitable for evaluating genotoxicity of soils.

A spill-over theory of international trade unionism

This paper use neo-functionalist and institutionalist theories of geo-political integration to develop a theory of international trade unionism. In brief, the theory asserts that the type of international ‘context’ in which international trade unions operate presupposes the types of ‘imperatives’ that will dominate their interests and concerns. These imperatives are taken to operate along one of three dimensions - industrial, political and ideological, and are seen as evolving in accordance with the ‘logic of spill-over’ in global and sub-global integration processes. Using this interpretation the discussion provides reasons as to why ideological imperatives have historically dominated international trade union thinking, the only exception being regional trade unions operating in Europe, which have evolved beyond the ideological to embrace industrial and political imperatives in their modes of organisation and operation.

Victorian local government reforms 1992-1999, revisited: implication for trade unions

Between 1992 and 1999 the Victorian State Government, Led by Jeff Kennett, set about implementing the most extensive public sector reform program ever witnessed in Australia, part of which involved significant changes in the organisation and operation of Local government. Although Local government had traditionally been 'the blind spot' in governmental arrangements, within three years of assuming office Local government had undergone major structural and operational change. This paper revisits this period by examining four elements of the reform agenda including the factors driving the reform, the Kennett government's approach to Local government reform, the expected outcomes sought by this government, and the policies implemented in Local government to achieve the expected outcomes. The paper identifies a number of implications for trade unions arising from this reform agenda and concludes that further investigation is warranted in this area.

Wastewater irrigation: the state of play

As demand for fresh water intensifies, wastewater is frequently being seen as a valuable resource. Furthermore, wise reuse of wastewater alleviates concerns attendant with its discharge to the environment. Globally, around 20 million ha of land are irrigated with wastewater, and this is likely to increase markedly during the next few decades as water stress intensifies. In 1995, around 2.3 billion people lived in water-stressed river basins and this could increase to 3.5 billion by 2025. We review the current status of wastewater irrigation by providing an overview of the extent of the practice throughout the world and through synthesizing the current understanding of factors influencing sustainable wastewater irrigation. A theme that emerges is that wastewater irrigation is not only more common in water-stressed regions such as the Near East, but the rationale for the practice also tends to differ between the developing and developed worlds. In developing nations, the prime drivers are livelihood dependence and food security, whereas environmental agendas appear to hold greater sway in the developed world. The following were identified as areas requiring greater understanding for the long-term sustainability of wastewater irrigation: (i) accumulation of bioavailable forms of heavy metals in soils, (ii) environmental fate of organics in wastewater-irrigated soils, (iii) influence of reuse schemes on catchment hydrology, including transport of salt loads, (iv) risk models for helminth infections (pertinent to developing nations), (v) microbiological contamination risks for aquifers and surface waters, (vi) transfer efficiencies of chemical contaminants from soil to plants, (vii) health effects of chronic exposure to chemical contaminants, and (viii) strategies for engaging the public.

Estuarine fish health assessment: evidence of wastewater impacts based on nitrogen isotopes and histopathology

Sewage effluent is a powerful agent of ecological change in estuaries. While the effects of sewage pollution on water quality are usually well documented, biological responses of exposed organisms are not. We quantified health impacts in the form of pathological tissue changes across multiple organs in estuarine fish exposed to elevated levels of treated wastewater. Structural pathologies were compared in wild populations of four fish species from two subtropical estuaries on the east coast of Australia that differ substantially in the amount of direct wastewater loadings. Uptake of sewage-derived  nitrogen by fish was traced with stable nitrogen isotopes. Pathologies were common in the liver, spleen, gill, kidney and muscle tissues, and included granulomas, melanomacrophage aggregates, and multiple deformities of the gill epithelia. Tissue deformities were more frequent in fish exposed directly to wastewater discharges. Mullet (Valamugil georgii) were most affected, with only a single specimen free of pathologies in the sewage-impacted estuary. Similarly, in those fish that had structural abnormalities, more deformities were generally found in individuals from sites receiving sewage. These spatial contrasts in impaired fish health correspond to significantly enriched δ₁₅N values in fish muscle as a consequence of fish assimilating sewage-N. Overall, the pattern of lower health and enriched δ₁₅N values in fish from sewage-impacted areas suggests that organism health is lowered by sewage inputs to estuaries. Measurements of organism health are required to understand the effects of sewage on estuarine ecosystems, and histopathology of fishes is a powerful tool to achieve this.

The structural events approach- A "better" way to understand long-term change in trade union structure: the Australian story (1986-96)

Traditional studies of long-term change in trade union structure have predominantly focused on aggregate trends in union merger activity in constructing explanations of change. Using the Australian trade union movement as an example, this article argues that our understanding of the long-term change in the external structure of trade unions would be better served by a structural events approach (Waddington, 1995) that examines the incidence of union formations, dissolutions, and breakaways, in addition to that of union mergers. In doing so, this article presents new data on structural change in the Australian trade union movement between 1986 and 1996, and explains the additional contribution made by union dissolutions and union formations to the reductionist effects of the merger wave that dominated these years.

Illegal migrants, tourism and welfare : a trade theoretic approach

Many countries receive illegal migrants but are reluctant to accept them due to possible negative externalities. We provide a rationale for not policing illegal migration by linking it to the tourism industry. By paying illegal migrants less than local workers, the relative price of the non-traded goods is shown to be lower than it would be in the absence of such workers. An expansion in tourist trade, under certain intensity conditions, necessarily raises resident welfare and employment. This tourist boom necessarily lowers the welfare of the illegal migrants. It is established that an increase in tourism increases the supply of illegal migrants.

The transfer of management accounting practices from London counting houses to the British North American fur trade

During the late eighteenth and early nineteenth centuries management accounting practices were transferred from London counting houses to the British North American fur trade. This transfer involved a set of practices that was more effective for implementing the strategy being pursued at the time than the set used with the previous strategy. London counting houses had developed management accounting practices to facilitate their backward integration strategies with America and the West Indies. Pivotal to this development was the requirement for sub-unit accountability and responsibility.
