Environmental impacts of tariff and tax reforms under origin and destination principles

The impacts of a point-by-point tariff/tax reform on the environment under the origin-based or destination-based tax principle are examined. The policy reform under the origin-based principle can raise the optimal pollution tax and, hence, improve the environment when the consumption demand and pollution are strongly substitutable, whereas the reform under the destination-based principle lowers the optimal pollution tax and, hence, worsens the environment. Nonetheless, when the consumption demand and pollution exhibit weak substitutes or even complements, the tariff/tax reform results in less environmental deterioration under the destination-based principle.

Comparative analysis of bilateral memoranda on anti-human trafficking cooperation between Thailand and three neighboring countries : what do the origin and the destination states agree upon?

In order to prevent, suppress and punish human trafficking, bilateral agreements between origin of victim countries and destination countries are crucial, because their cooperation involves cross-border activities such as repatriation of victims, extradition of criminals and information-sharing. This article analyzes three bilateral legal instruments between The Government of The Kingdom of Thailand and her three neighboring countries, namely The Royal Government of Cambodia, The Government of Lao People's Democratic Republic and The Government of The Union of Myanmar. The analysis will examine the legal status of the victim, the victim as witness in criminal proceedings, the victim protection programs, the recovery and restitution of damages, the process of repatriating the victim, and the prosecution of the criminal.

Origin and Availability of Large Cavities for Barrow’s Goldeneye (Bucephala islandica), a Species at Risk Inhabiting the Eastern Canadian Boreal Forest

Large secondary-nesting birds such as ducks rely on appropriate cavities for breeding. The main objective of this study was to assess the availability of large cavities and the potential of a managed boreal coniferous landscape to provide nesting trees within the breeding area of the eastern population of Barrow’s Goldeneye (Bucephala islandica), a cavity-nesting species at risk in Canada. Woodpecker surveys were conducted in both conifer and mixed-wood landscapes, and cavities were sought in line transects distributed in unharvested and linear remnant stands of balsam fir (Abies balsamea) and black spruce (Picea mariana) as well as in cutblocks. No Pileated Woodpeckers (Dryocopus pileatus) were detected in the breeding area of Barrow’s Goldeneye, but the species was present in the nearby lowland area in which trembling aspen (Populus tremuloides) is abundant. Only 10 trees (0.2% of those sampled) supported cavities considered suitable for Barrow’s Goldeneye in terms of dimensions and canopy openness. Most of the suitable cavities found during this study were nonexcavated apical (chimney) cavities in relatively short snags that showed advanced states of decay. A diameter-at-breast-height threshold was determined for each tree species, after which the probability of cavity occurrence was enhanced in terms of potential cavity trees for Barrow’s Goldeneye. Remnant linear forest sites had lower potential tree densities than did their unharvested equivalents. Large cavities were thus a rare component in this boreal landscape, suggesting that they may be a limiting factor for this population at risk. Current even-aged forest management that mainly relies on clear-cut practices is likely to further reduce the potential of this landscape to provide trees with suitable cavities.

Sports-events, tourism and destination marketing strategies: an Australian case study of Athens 2004 and its media telecast

The focus of this study was the media telecast of the Athens 2004 Summer Olympic Games. The study explored the efficacy of the Australian telecast in developing positive perceptions and attitudes of Greece as a tourist  destination and was origin-based—in that a survey was undertaken of a sample of Australian residents (n = 350). Participants were segmented based on their post-consumption perceptions of Greece. Four segments were identified and labelled—'extremely positive' (n = 75), 'highly positive' (n = 153), 'positive' (n = 83) and 'negative' (n = 29). Statistical differences were found between the segments based on whether attitudes towards Greece had improved as a result of their consumption of the media telecast of the Athens 2004 Olympic Games (Athens 2004). To gain insights into this phenomenon, open-ended responses provided by segment members were then analysed.

Across the sample, 38.7% of respondents indicated that their overall attitude towards Greece as tourist destination changed as a result of their consumption of the telecast of Athens 2004. Considering that the attitudes of participants in the current study improved, not as a result of first-hand experiences at the destination, but as a result of their vicarious experiences of the destination through consumption of a media telecast of a special event, the results provide insights to the efficacy of this particular telecast in developing positive attitudes with regard to Greece as a tourist destination. The results of this study could be used a benchmark for future event-related destination marketing strategies. Similarities and differences emerged between the segments with regard to the reasons as to why members of each of the clusters attitudes towards Greece as a tourist destination had improved as a result of their consumption of the telecast. While their responses appeared to be similar, the frequency in which the concepts emerged for each of the segments varied intensity. The key issues that emerged for the four clusters were the appearance of Greece; culture and history of Greece; capacity, or 'hostability', of Greece to stage the Athens 2004; and infrastructure in Greece.

Genetic diversity in Colletotrichum gloeosporioides from Stylosanthes spp. at Centers of origin and utilization

Using molecular markers, this work compares the genetic diversity in Colletotrichum gloeosporioides infecting species of the tropical forage legume Stylosanthes at the center of origin in Brazil and Colombia with that of Australia, China, and India, where Srylosanthes spp. have been introduced for commercial use. There was extensive diversity in the pathogen population from Brazil, Colombia, China, and India. The Australian pathogen population was least diverse probably due to its geographical isolation and effective quarantine. The extensive diversity in China and India means that threats from exotic pathogen races to Stylosanthes pastures can potentially come from countries outside the South American center of origin. In Brazil and India, both with native Stylosanthes populations, a high level of genetic differentiation in the pathogen population was associated with sites where native or naturalized host population was widely distributed. There was limited genetic diversity at germplasm evaluation sites, with a large proportion of isolates having identical haplotypes. This contrasts recent pathogenicity results for 78 of the Brazilian isolates that show hot spots of complex races are more common around research stations where host germplasm are tested, but few are found at sites containing wild host populations. For a pathogen in which the same races arise convergently from different genetic backgrounds, this study highlights the importance of using both virulence and selectively neutral markers to understand pathogen population structure.

Origin and patterns of distribution of trace elements in street dust. Unleaded petrol and urban lead

The elemental composition, patterns of distribution and possible sources of street dust are not common to all urban environments, but vary according to the peculiarities of each city. The common features and dissimilarities in the origin and nature of street dust were investigated through a series of studies in two widely different cities, Madrid (Spain) and Oslo (Norway), between 1990 and 1994. The most comprehensive sampling campaign was carried out in the Norwegian capital during the summer of 1994. An area of 14 km2, covering most of downtown Oslo and some residential districts to the north of the city, was divided into 1 km2 mapping units, and 16 sampling increments of approximately 150 g were collected from streets and roads in each of them. The fraction below 100 μm was acid-digested and analysed by ICP-MS. Statistical analyses of the results suggest that chemical elements in street dust can be classified into three groups: “urban” elements (Ba, Cd, Co, Cu, Mg, Pb, Sb, Ti, Zn), “natural” elements (Al, Ga, La, Mn, Na, Sr, Th, Y) and elements of a mixed origin or which have undergone geochemical changes from their original sources (Ca, Cs, Fe, Mo, Ni, Rb, Sr, U). Soil resuspension and/or mobilisation appears to be the most important source of “natural” elements, while “urban” elements originate primarily from traffic and from the weathering and corrosion of building materials. The data for Pb seem to prove that the gradual shift from leaded to unleaded petrol as fuel for automobiles has resulted in an almost proportional reduction in the concentration of Pb in dust particles under 100 μm. This fact and the spatial distribution of Pb in the city strongly suggest that lead sources other than traffic (i.e. lead accumulated in urban soil over the years) may contribute as much lead, if not more, to urban street dust.
