Published: December 2014

A waste water treatment plant (WWTP) adopts sequencing batch reactor (SBR) process, which exist the problem of instable treatment effect on denitrification and dephosphorization. The total nitrogen (TN) and total phosphorus (TP) of the effluent could not reach the class A standard of discharge standard of pollutants for municipal wastewater treatment plant (GB18918-2002) (hereinafter referred to as the class A standard) as a result of different order in utilizing the carbon source between nitrification and denitrification. The step-feed procedure is used to improve the efficiency of denitrification and dephosphorization. Field experiments about the effects of the different influent distribution ratio (marked as λ) on denitrification and dephosphorization were carried out and the results showed that the effect of the effluent TN is the best and other indexes could also achieve class A standard when λ is 5:3.

Effects of Increasing Alkali Catalysts Concentration on Hydrogen Gas Yield during the Supercritical Water Gasification of Food Waste
Authors: Amuzu-Sefordzi Basil , Huang Jing Yu
Published: December 2014

Supercritical water gasification (SCWG) of food waste was carried out to investigate the effects of increasing alkali catalysts (NaOH, KOH, Ca (OH)2, Na2CO3, NaHCO3and K2CO3) concentration on hydrogen yield. Food waste containing twenty-eight different Chinese food items was gasified at a temperature of 400°C (held for 10mins) and pressure of 24MPa. The basicity of the reacting medium was an underlying factor influencing the effects of the different alkali catalysts concentrations on the hydrogen yield. In this study, KOH generally had the highest catalytic effects on hydrogen yield. Additionally, increasing the concentration of alkali catalysts significantly suppressed the CO2content in the product gases. Suppression of CO2by NaOH and KOH was due to their catalytic effects during the water gas shift reaction (WGSR) in order to increase the hydrogen yield. Suppression of CO2by carbonates on the other hand was due to their catalytic effects on the methanation reaction, thereby hindering the WGSR and resulting in lower hydrogen yields. Finally, increasing NaOH concentrations was very effective to decarbonize the product gas of the various reactions. This study seeks to discriminate the effects of increasing alkali catalysts concentration on hydrogen yield during the SCWG of food waste.

Authors: Zheng Xiao Yuan , Wang Bo , Chi Yong , Jin Yu Qi
Published: December 2014

Oily sludge is inevitably produced in numerous petroleum processing operations. Five oily sludge samples were collected to identify the compositions and to characterize the extracted solids. The results indicated that three fifths of the samples contained significant amounts of oil and could be potentially recovered as energy resources. All of the samples had high concentration of water. The compositions of C, H, and N, as well as H/C in the separated oils were close to those in oil sands bitumen. The high concentration of asphaltenes agreed with the low H/C. The XRD spectra showed that the major minerals contained in the extracted solids were quartz and calcite.

Authors: Kang Xiao Rong , Liu Ya Li
Published: December 2014

Potassium ferrate was used to enhance sludge dewatering and the mechanism was studied. Sludge floc structure was effectively destroyed by potassium ferrate, and the soluble COD, proteins and polysaccharides increased with the increase of potassium ferrate. The optimal dose for sludge disintegration was 100 mg/gSS, and the corresponding maximal SCOD, soluble proteins and polysaccharides concentrations were 2455, 800 and 145 mg/L, respectively. Sludge dewaterability was enhanced significantly with cationic polyacrylamide (C-PAM) application, and the SRF decreased to 0.72×1010m/kg from 50.12×1010m/kg. This study indicated that the potassium ferrate pretreatment was helpful for enhancing sludge dewaterability and reducing the coagulant dose.

Authors: Wang Li Li , Yang Qian
Published: December 2014

The research in this paper focuses on improving the COD removal rate of the coking wastewater and the NH3-N removal rate and thus diversifying measures to dispose microbial floras in wastewater from the coal chemical industry. The means of adding nutrients, acid treatment and coagulation sedimentation react synergistically to dispose the organic contaminants in the coking wastewater. We attempted to combine Saccharomyces cerevisiae, Torula yeast, tropical Candida mycoderma, etc. to exploit the respective advantages to the full and improve the disposal effect. According to the COD sample (27000-30000) and NH3-N (2500-3000) offered by the client company, the COD removal rate ranged from 24.2% to 31.8% in the mixed experiment group of Saccharomyces cerevisiae and Torula yeast, with NH3-N removal rate from 63.5% to 69.6%. Obviously, the NH3-N removal rate produced good effect. Meanwhile, the COD removal rate ranged form 35.3% to 41.8% in the experiment group only adjusting PH value and the NH3-N removal rate ranged from 40.2% to 50.2%. It is obvious that NH3-N removal rate is influenced by the amount of bacterial strain.

Authors: Li Ruo Zheng , Yang Hong , Jin Xin
Published: December 2014

Lignite activated carbon was provided through lignite which is treated specially. The adsorption capacity and mechanism of COD from Coal gasification wastewater by lignite activated carbon have been studied.The adsorption capacities of lignite activated carbon at different times were obtained by concentration of COD in the remainder solution. Three simplified kinetic models: pseudo-first-order, pseudo-second-order, intraparticle diffusion equations were adopted to examine the mechanism of the adsorption process. The results showed that the adsorption can be expressed by the pseudo-second-order model. The adsorption balance capacity was obtained as 50.8mg·g-1 (298K), and the adsorption balance capacity decreased with increasing of temperature, which showed that the adsorption process was exothermic. The adsorption activation energy (Ea) was calculated as 5.76kJ·mol-1, and it showed that the adsorption process was Physical adsorption. This study explored new treatment channels for lignite comprehensive utilization..

The experiment disposing waste water with dilute acetic acid aimed to recycle acetic acid and synthesize high value added n-butyl acetate with cetyl trimethyl ammonium bromide (CTMAB) as the phrase transfer catalyst. Over-dose n-butanol was added and n-butyl acetate was extracted with the mixed solution of trioctylamine (TOA) (20%,w) and tributylphosphate (TBP) (80%,w) as the extractant. After the still standing and liquid separation, the organic phase was depressurized and distilled under the pressure 25kPa.The n-butanol and a part of acetic acid were recycled, and n-butyl acetate was collected between temperature 70°C-75°C. The synthetic process parameters were optimized, that was: CTMAB 0.35g /0.127mol acetic acid, TOA/TBP 30ml, the ratio of alcohol and acid 1.3:1.0, reaction time 2.5h, reaction temperature 30°C.The extraction rate of acetic acid was 88.2%.The yield of n-butyl acetate was 81.3% and phrase transfer catalyst with extractant was recycled for 6 times whose effect was reduced a little but good enough. This experiment, which included esterification reaction with phase transfer catalyst and extractive distillation process, has received a satisfactory effect and can be used in similar system.

Authors: Melchert Maura Berger Maltez , Viana Marcelo Mendes , Dweck Jo
Published: December 2014

This paper presents the study of the simultaneous use of two residual catalysts (RAl and RNi) with type II Portland cement, in order to avoid environmental impacts and to use of the solidified products as structural sustainable materials. The solidification/stabilization (S/S) was evaluated by thermogravimetric analysis, X ray diffraction, leaching and compressive strength tests. Mortars with water/cement mass ratio equal to 0.5 were prepared, into which, different percentual masses of each waste were added. The main phases formed due to the retarding and accelerating actions of each waste were evaluated by thermogravimetry and X ray diffraction after 28 days of hydration. The leaching tests done with the solidified mortars presented values of Ni and Al contents below maximum accepted limits, indicating that they attend to environmental legislation, as well as eliminate the original environmental impact of the original wastes. Mortars evaluated after 28 days by compressive strength tests, presented acceptable results for their possible use as construction materials.

Published: December 2014

Two pathways for chemical modification of wastes from an Amazon hardwood species named Cordia goeldiana were proposed in this work. Variations in reaction time (2 h or 0.5 h) and temperature (80 and 150 °C), besides reaction medium (mechanical stirring or pressurized closed system) were tested for alkali treatment. NaOH at 5% was kept for both conditions. Afterwards, bleaching with H2O2 and NaOH was performed, but reaction conditions were held constant for both pathways. In general, the mild alkali treatment resulted mainly in the removal of extractives and hemicelluloses from the raw sawdust. The onset temperature and crystalline index increased. On the other hand, the use of higher pressure and temperature in alkali treatment at closed system had a remarkable lignin removal and crystalline index increase without changing cellulose polymorphism as the main effects, but thermal stability became lower. Apart from mineral residues removal, bleaching had negligible effects on fiber properties, suggesting that this procedure could be avoided.
A Study of the Nature of the Shear Strength of Soil-Waste Composites

Published: December 2014

The soil is a brittle material compared to other engineering materials such as steel, concrete and wood. The clayey nature of the soils of western Paraná causes them to be chemically reactive towards certain compounds, thereby improving their engineering properties, especially its mechanical strength. The study involved treating the typical soil of the region with two residues from industrial and human activities: rice husk ash (RHA) at doses 0; 2.5; 5; 7.5 and 10%; and burned sewage sludge (BSS) at doses 0; 5; 10; 15 to 20%; in the dry soil mass. The test samples were compacted in Mini-MCV equipment and broken in triaxial compression tests of consolidated undrained type, with confining pressures of 25; 50 and 100 kPa. The results showed that both the RHA change dramatically as the BSS which passes viscoelastic plastic-linear mechanical behavior of the composites. There was a significant increase in deviator tension and elasticity modulus, implying a gain in strength and stiffness of the composite compared to the natural soil. The most striking effect was observed in the RHA cohesion parameter; while the substantial effect of BSS was observed in the interparticles friction angle. These results suggest that RHA promoted the formation of new products filling the pore space of the composite, changing the clayey material in a nature of a continuum, while the BSS promoted a substantial aggregation of the particles, wherein the soil reinforcement transformed clay in a particulate material coarser grain size.

Published: December 2014

The incorporation of lightweight aggregates in cement-based coating mortars contributes to a better performance of some of their physical properties, influencing their hygrothermal behaviour. This paper analyses the effect of some lightweight aggregates (expanded clay, granulated cork and silica aerogel) on the following mortars’ characteristics: porosity, bulk density, capillary water absorption coefficient, drying index and water vapour permeability. The experimental results showed that low percentages of incorporation of lightweight aggregates led to more porous mortars with lower bulk density, higher capillary water absorption coefficient and greater drying facility, relative to the reference cement-based mortar. The incorporation of silica aerogel in cement-based mortars resulted in major differences in terms of water resistance, with significant benefits in terms of the drying process due to their porous structure.

Published: December 2014

The heritage of fair-faced concrete, largely built in the twentieth century and nowadays recognized as heritage to be protected, is susceptible to attacks by graffiti, a form of vandalism that causes a major social and economic impact on society. Concrete is a porous material sometimes deteriorated over the years, and the interactions between the inks and the substrate and removal methods sometimes deteriorate or alter the concrete surface, especially if it is necessary to repeat the removal process. The anti-graffiti products are applied on the surface of the concrete, hindering the adhesion of paints or preventing its penetration into the pores of concrete, which in turn facilitates their removal. However, it appears that many of the existing protective products on the market may also alter the surface characteristics of the concrete irreversibly. Considering that the durability of concrete depends on the composition and characteristics of the surface, it is essential to know the effects of anti-graffiti protection systems on the durability of concrete and adopt the appropriate methodology to preserve this heritage. Thus, an experimental program was developed for analyzing changes in durability indicators and surface properties that protect concrete from deterioration (i) concrete without protection before and after application of spray paint, (ii) concrete with protection before and after application of spray paint and (iii) after paint removal were studied. Two anti-graffiti products were evaluated: a permanent and a sacrificial one. Effects of the anti-graffiti systems on the concrete durability are investigated and the tests performed include: water absorption by capillary and immersion at atmospheric pressure. The results of the water absorption tests show that the graffiti protection reduces the water absorption into the concrete and facilitates the removal of the graffiti without affecting negatively the characteristics of the surface and thus contributing to improve its durability.

Published: December 2014

Unsaturated polyester based composites materials present several improved properties over conventional materials. However, these composites show great sensitivity to high temperatures and poor fire behaviour. In the present study, an effort is undertaken to develop new unsaturated polyester composites with improved fire reaction behaviour by matrix modification with hybrid flame retardant systems based on nanooxides and phosphinates. For this purpose, a series of composite formulations containing different contents and types of both metal oxide nano/micro particles and organic phosphinates were manufactured, with basis on the Taguchi L9 orthogonal array, and tested for fire reaction and mechanical properties. The data treatment was carried out through analyses of variance. Fire reaction properties were analysed and quantified by the vertical flammability test (UL-94), and the mechanical properties were studied by flexural, Shore D, and Charpy impact tests. The results were compared with those obtained for plain resin specimens. Test results revealed that the addition of hybrid flame retardant systems introduced reasonable improvements in at least one fire reaction property. However, it was verified that the filler addition led to a decrease in mechanical properties, probably due to poor matrix-filler adhesion. Further studies are required in order to improve the mix design formulations.

Probabilistic Modelling and the k-Value Concept
Authors: Teplý Břetislav , Chromá Markéta , Rovnaníková Pavla , Strauss Alfred
Published: December 2014

The durability of concrete structures is an important issue. Eurocode EN 206-1 introduces the k-value concept for concretes made with supplementary cementitious materials; a prescriptive concept that recommends limiting water/cement ratio values for a specified exposure class. A more advanced performance-based concept directly requires that concrete be designed in terms of performance-related parameters, an approach which seems to be more suitable when durability must be achieved. The application of mathematical models in durability assessment is advocated, and an example is shown.

Published: December 2014

The paper is focused on the study of the material changes which can occur on the basis of mechanical and thermal loading in relation to the functional surfaces of the construction parts. The structural or the mechanical changes can be influenced by ambient environment and in this case, it is the influence of liquid media. The water, hot metal as well as molten glass can be the representatives of the mentioned liquid medium. In relation to the influence of the liquid medium, there is the danger of superposed wears while one of these wears is considered as dominant. Furthermore, occurrence of the corrosion process leads to the increases of the given dominant wear. In relation to the analysis and evaluation of the wear, the simulated tests under the critical conditions are necessary for the correct and precise prediction of the degradation processes. Experimental measurements can be used for the prediction of the material behaviour under the critical operation conditions. In the given work, the attention was paid to the selected materials which were exposed to the mechanical as well as mechanical-thermal loading. The important parameters were achieved with help of the testing device which was modified in a special way. Moreover, the structure changes were observed for the different time intervals or periods. On the basis of the susceptibility to the loading, the conclusions as well as recommendations were summarized for the selected materials.

We report a case of hand, foot and mouth disease (HFMD) in a 5-year-old male from Merida City in the Yucatan Peninsula of Mexico. A clinical and physical examination revealed that the patient had symptoms typical of HFMD, including fever, fatigue, odynophagia, throat edema, hyperemia, lesions on the hands and feet, and blisters in the oral cavity. The patient fully recovered after a convalescence period of almost three weeks. Reverse transcription-polymerase chain reaction and nucleotide sequencing revealed that the etiological agent was enterovirus 71 (EV71). The sequence has greatest (90.4%) nucleotide identity to the corresponding regions of EV71 isolates from the Netherlands and Singapore. Although HFMD is presumably common in Mexico, surprisingly there are no data in the PubMed database to support this. This case report provides the first peer-reviewed evidence of HFMD in Mexico.
Continental-scale impacts of intra-seasonal rainfall variability on simulated ecosystem responses in Africa

Published: December 2014

Abstract. Climate change is expected to modify intra-seasonal rainfall variability, arising from shifts in rainfall frequency, intensity and seasonality. These intra-seasonal changes are likely to have important ecological impacts on terrestrial ecosystems. Yet, quantifying these impacts across biomes and large climate gradients is largely missing. This gap hinders our ability to better predict ecosystem services and their responses to climate change, especially for arid and semi-arid ecosystems. Here we use a synthetic weather generator and an independently validated vegetation dynamic model (SEIB-Dynamic Global Vegetation Model, DGVM) to virtually conduct a series of "rainfall manipulation experiments" to study how changes in the intra-seasonal rainfall variability affect continent-scale ecosystem responses across Africa. We generate different rainfall scenarios with fixed total annual rainfall but shifts in (i) frequency vs. intensity, (ii) rainy season length vs. frequency, (iii) intensity vs. rainy season length. These scenarios are fed into SEIB-DGVM to investigate changes in biome distributions and ecosystem productivity. We find a loss of ecosystem productivity with increased rainfall frequency and decreased intensity at very low rainfall regimes (<400 mm year−1) and low frequency (<0.3 event day−1); beyond these very dry regimes, most ecosystems benefit from increased frequency and decreased intensity, except in the wet tropics (>1800 mm year−1) where radiation limitation prevents further productivity gains. This result reconciles seemingly contradictory findings in previous field studies on the impact of rainfall frequency/intensity on ecosystem productivity. We also find that changes in rainy season length can yield more dramatic ecosystem responses compared with similar percentage changes in rainfall frequency or intensity, with the largest impacts in semi-arid woodlands. This study demonstrates that intra-seasonal rainfall characteristics play a significant role in influencing ecosystem function and structure through controls on ecohydrological processes. Our results suggest that shifts in rainfall seasonality have potentially large impacts on terrestrial ecosystems, and these understudied impacts should be explicitly examined in future studies of climate impacts.

Trabalhadores em Hotelaria e a Produção do Discurso Turístico
Authors: Dartora Juliana Souza , Gastal Susana
Published: December 2014

Pesquisa exploratória realizada na cidade de Caxias do Sul/RS, que buscou analisar a produção de discursos associados ao Turismo, pelo trabalhador do setor hoteleiro local. Utilizam-se conceitos e premissas da Psicologia Social, em especial dos seus construtos ‘percepção’ e ‘atitude’, e as teorizações da Comunicação Social, sobre imaginários. A metodologia de análise também recorre à análise do conteúdo, conforme proposta por Bardin (1997), no âmbito dos estudos da Comunicação. Nos resultados, aponta-se que os sujeitos não consideram satisfatória a relação da cidade com a atividade turística, quando a mesma é comparada a outras localidades da mesma região, atribuindo o fato, entre outros, a que as demais localidades teriam maior presença na mídia e que, em Caxias do Sul, a atividade industrial seria predominante à turística. Constata-se a reprodução de um imaginário consagrado pela OMT, no qual o turismo seria associado exclusivamente ao lazer. Entretanto, a categoria turismo de negócios é recorrente na fala dos trabalhadores.
Influências das Políticas Públicas de Turismo nas Transações entre os Agentes: uma análise sob a ótica da ECT
Authors: Gomes Bruno Martins Augusto , Santos Antônio Carlos
Published: December 2014

As políticas federais de turismo têm se pautado na articulação dos agentes locais. Porém, antes deste enfoque ser adotado nas políticas federais, Minas Gerais já o utilizava, por meio da Política de Circuitos Turísticos. Novas políticas provocam alterações nas transações entre os agentes de um setor. Por isso esse trabalho buscou verificar a influência da Política de Circuitos Turísticos nos comportamentos dos agentes e nas transações. A pesquisa demonstrou que a política de circuitos turísticos de Minas Gerais criou uma estrutura de governança, que possibilitou um aumento da freqüência das relações entre eles, reduziu a incerteza, o oportunismo e a possibilidade dos investimentos em ativos específicos serem perdidos. Por isso, nas regiões pesquisadas, acredita-se que a política de circuitos turísticos tenha contribuído para a redução dos custos de transação. Contudo, mudanças na gestão dos Circuitos e no comportamento dos agentes, ainda são necessárias para a redução significativa os custos de transação.

O presente número da Revista Brasileira de Pesquisa em Turismo – RBTur marca a quinta revista editada por esta equipe. Nele, destacamos alguns dos diferentes métodos e metodologias de pesquisa que podem ser aplicadas ao estudo do Turismo, tão diversas quanto diverso é o fenômeno que nos ocupa. O Turismo pode ser abordado mediante pesquisa qualitativa ou quantitativa, pode ser analisado com o método dialético para mostrar as suas contradições, ou com o método hipotético dedutivo para comprovar hipóteses sobre relações causa-efeito. Podem ser usados tanto o procedimento histórico, quanto o monográfico, o comparativo, o estatístico, o funcionalista e o estruturalista indistintamente ou combinados, em função do que se quer estudar. Como técnicas da metodologia de pesquisa, pode ser adotado variado instrumental, tais como questionários, entrevistas, até histórias de vida, pesquisa bibliográfica, documental, pode se fazer observação, observação participante ou etnografia, cujos resultados também podem ser analisados de variadas formas. No artigo do professor Ascanio vemos a aplicação da análise de conteúdo, para pesquisar a influência dos meios de comunicação na percepção de um problema na área de Turismo. Embora as fontes de dados remontem a duas décadas, apresenta grande atualidade, no que pode estimular outros pesquisadores a realizar estudos comparativos com a nossa atualidade. O estudo de Argôlo e Bomfim utiliza a análise de discurso, não se restringindo apenas aos conteúdos dos textos (palavras-chave), mas ao sentido das falas dos entrevistados para analisar o planejamento de Turismo nas comunidades da Costa do Cacau. No artigo de Beares e Cabral, que estudam a hospitalidade em comunidades tradicionais, podem ser identificados métodos provenientes da antropologia e da psicologia social, tais como a etnografia e os estudos de percepção. Estudos de marketing são aplicados ao Turismo por Miguel e Silveira para avaliar o estado da arte de um destino turístico do estado de Santa Catarina. O estudo de Sagi mostra o ecletismo na utilização de métodos e procedimentos, trabalhando com pesquisa bibliográfica, documental, questionários e observação. Para encerrar, uma crítica a um livro eclético que fala em patrimônio, história, turismo e sociedade e uma crônica de um evento que reuniu turismólogos em um congresso de antropologia. Este número reafirma a riqueza do turismo enquanto objeto de pesquisa a partir das mais diversas abordagens e formações, e suas infinitas interfaces com outras esferas de atuação do homem em sociedade.

O objetivo deste estudo foi analisar as quatro variáveis (produto, preço, praça e promoção) que formam o composto de marketing de uma cidade turística no litoral de Santa Catarina, na visão dos representantes dos setores públicos e privados deste destino turístico, e não com os seus usuários. A tipologia da pesquisa utilizada foi exploratória e descritiva e o método de coleta de dados foi qualitativo através de entrevistas com roteiro semi-estruturado. Os resultados obtidos durante a investigação revelaram que este destino ainda não está estruturado o suficiente para ser considerado um produto turístico, pois atualmente passa por uma transição, mudando o foco de turismo de ‘sol e mar’ para o turismo de natureza e sua infraestrutura ainda necessita de investimentos, principalmente em saneamento e acessos. O elemento preço foi considerado adequado na visão dos empresários e altos demais na opinião do setor público, que percebe exageros por parte dos equipamentos turísticos. A distribuição da cidade no mercado turístico acontece principalmente de forma direta, sem a participação de intermediários (operadores e agentes turísticos) e para a promoção do destino as ferramentas utilizadas vão desde a participação em eventos turísticos, matérias e anúncios em revistas do setor e na internet. As ações são realizadas de forma pouco planejada, sem parcerias entre o trade e o Poder Público e também sem integração com as outras variáveis do composto de marketing influenciando diretamente no desempenho deste destino no mercado turístico.
Inclusão social, cidadania e turismo – uma investigação sobre a existência de serviços adaptados às pessoas com necessidades especiais nos meios de hospedagem da região metropolitana de Curitiba
Authors: Kushano Elizabete Sayuri , Almeida Wolney Gomes
Published: December 2014

O presente trabalho reflete sobre a importância da inclusão social no Turismo, especialmente junto às pessoas com necessidades especiais. Aborda o conceito de inclusão social e o direito do exercício da cidadania. Como procedimento metodológico utilizou-se de uma busca em todos os sites oficiais dos meios de hospedagem da Região Metropolitana de Curitiba (RMC) com o intuito de verificar se em tais há adequações (instalações, equipamentos, serviços etc.) para o hóspede com necessidades especiais, bem como investiga (e/ou confirma), por meio de entrevista por telefone, quantas unidades habitacionais adaptadas existem no meio de hospedagem e qual(is) necessidade(s) especial(is) é (são) atendida(s). Foram identificados 115 meios de hospedagem na RMC com site em funcionamento no período da pesquisa. Desses, 25 informam ter unidades habitacionais adaptadas (UHs), totalizando 37 UHs em toda a RMC. Porém, todas são direcionadas para cadeirantes. Raros meios de hospedagem possuem informação em braile e nenhum possui atendimento em língua de sinais. A inclusão social e cidadania refletem em expor empresas socialmente responsáveis. Seja pelo caráter da filosofia da própria empresa, ou mesmo para cumprir determinada legislação, como também para assegurar uma boa imagem perante a sociedade, o fato é que ter produtos e serviços que abarquem a inclusão de pessoas com necessidades especiais está, felizmente, sendo menos incomum.

BEECH, John; CHADWICK, Simon. (Eds). The business of Tourism Management. Londres: Prentice Hall, 2006. 577 p. (19,5cm x 26,5 cm). The business of Tourism Management foi editado por John Beech (Coventry Business School, Coventry University) e Simon Chadwick (Birkbech College, University of London).O livro em questão contou com a participação de outros 26 renomados autores de turismo que escrevem em língua inglesa. São 24 capítulos divididos em três partes, a saber: Parte 1 – The context of tourism; Parte 2 – Business functions applied to tourism; Parte 3 – Management issues specific to tourism businesses. The business of tourism management, é uma preciosa ferramenta para professores e estudantes de turismo que dominam o idioma inglês. O papel utilizado para fazer o livro é originário de florestas sustentáveis, de qualidade e com diagramação que evita que a leitura torne-se cansativa. Pela qualidade do texto e pela qualidade geral do material a editora fez um alto investimento, o que leva a crer que este livro foi escrito para concorrer com os principais manuais de turismo existentes do mercado. Por ter uma abordagem generalista, o texto perde um pouco em profundidade, mas mesmo assim alcança o objetivo ao qual se propõe.

Authors: Loch Carlos , Walkowski Marinês da Conceição
Published: December 2014

O presente artigo é resultado de uma Dissertação de Mestrado que teve como tema principal o planejamento participativo como instrumento do planejamento turístico do Município de Alfredo Wagner-SC. Este estudo se justifica ao identificar as modificações no espaço rural do Município, onde os agricultores têm enfrentando dificuldades na geração de renda e buscam dinamizar as atividades agrícolas e não-agrícolas por meio do turismo. O objetivo deste artigo é analisar o processo participativo, visando mobilizar e sensibilizar os agricultores e agentes locais para o interesse turístico, sendo a participação um fator indispensável no planejamento turístico. Para tanto, a metodologia será uma pesquisa exploratória, a fim de descrever as características do Município e realizar um levantamento bibliográfico sobre o tema proposto. Como resultado desta pesquisa, foi observado, a falta de diálogo entre os principais órgãos públicos e a necessidade de buscar parcerias com a iniciativa privada. Contudo, foi possível mobilizar e sensibilizar os envolvidos por meio de uma análise da situação atual e futura, identificando as principais necessidades para o desenvolvimentoturístico no Município.

Authors: Delphino Rodrigo de Benedictis
Published: December 2014

Esta pesquisa, realizada no município de São Sebastião, litoral norte do Estado de São Paulo teve como objetivo estudar o patrimônio natural e cultural. Ambos vêm sendo pressionados, de um lado pelo desenvolvimento econômico do porto, que vem crescendo e destacando-se na região, do outro, pela presença da Petrobrás que se encontra em franca expansão, e também do Turismo desenvolvido especialmente nas praias mais afastadas do centro do município. Destaca-se que o corpus da pesquisa foi construído por conveniência, a partir da indicação do primeiro depoente. Foi adotado o tipo de abordagem qualitativa, baseado nos depoimentos de quatro entrevistados, dois moradores e dois turistas de segunda residência que testemunharam transformações no município. O resultado da pesquisa foi que o patrimônio, tanto natural quanto cultural, está em risco, faltando propostas efetivas de preservação, assim como um planejamento urbanístico e turístico que se adéqüem as necessidades do município.

Cooperativas de Turismo: Uma Estratégia ao Desenvolvimento Turístico Integrado - Análise do Roteiro dos Imigrantes (Paraná, Brasil)
Authors: Mielke Eduardo Jorge Costa
Published: December 2014

Este artigo estabelece uma relação entre o tripé: cooperativismo, turismo rural e desenvolvimento fazendo uma abordagem destes elementos na análise do Roteiro dos Imigrantes, Estado do Paraná. O cooperativismo surge da necessidade de se unir esforços a fim de melhorar os processos de gestão. Este tipo de economia social tem inúmeras vantagens como instrumento de desenvolvimento do turismo rural, na medida em que um dos principais problemas do turismo rural encontra-se na fragmentação da oferta e na comercialização dos seus produtos e o cooperativismo une esforços e promove ações conjuntas e planejadas no sentido de organizar esta oferta agregando valores na formação do produto turístico e sua consolidação.

WHY RISK WHY NOW? CONCEPTUAL PROBLEMS AROUND THE RISK PERCEPTION IN TOURISM INDUSTRY
Authors: Korstanje Maximiliano Emanuel
Published: December 2014

Even though the risk perception theory has been coined by Cognitive Psychology and widely used during more than 40 years, only after September 11th 2001 the term risk was borrowed to tourism fields. The psychological and symbolic impacts that generated the WTC attacks drew the attention of many scholars concerned by the destination image. However, based on assumptions that need to be revisited, this body of knowledge rests on shaky foundations simply because its working definition of risk seems not to be correct. In addition, risk perception theory nourishes a discourse enrooted in a radicalized construction of otherness whose characteristics scare us. To some extent, risk perception theory in tourism has much to say but in fact some previous points should be previously discussed.

TURISMO Y RECURSOS TERMALES: EL CASO DE LA INSTALACIÓN DEL PARQUE TERMAL DE LA CIUDAD DE VICTORIA, ENTRE RÍOS, ARGENTINA
Authors: Carreras Julia Piñeiro
Published: December 2014

En este artículo analizo el proceso de instalación de un parque termal (2003-2010) que se da en el contexto de la transformación de la localidad de Victoria (Entre Ríos, Argentina), en una ciudad turística. Para ello, utilizo materiales producidos en una investigación antropológica de carácter etnográfico, así como una diversidad de documentos periodísticos y de carácter legislativo. Con el fin de mostrar el carácter activo de específicos actores locales en la turistificación de la ciudad, reconstruyo el proceso de instalación del parque termal contextualizándolo en el marco de las discusiones tendientes a la modificación de las normativas referidas al aprovechamiento turístico del agua termal en la provincia. Atiendo especialmente al papel que, en la llegada de este nuevo emprendimiento, ocuparon específicos actores sociales del ámbito empresarial y estatal, y a las relaciones que entablaron entre sí.
