A bioeconomic evaluation of a commercial scale recirculating finfish growout system - an Australian perspective

This study, based on 3 years of commercial data, presents the results of an economic analysis of a 20-tonne per annum (TPA) commercial recirculating aquaculture system (RAS) facility located in Warrnambool, Victoria, Australia. Based on the assumptions of the analysis, results highlight the non-viability of the facility, with a 10-year projected negative cumulative cash flow of − $648,038, and negative net present value (NPV) of − $707,546. Economies of scale were assessed by the development of economic models for hypothetical 50-TPA and 100-TPA facilities, based on the actual figures obtained from the 20-TPA case study. These analyses highlighted marginal viability for the 50-TPA facility (with a ten-year projected cumulative cash flow of $1,030,300; negative NPV of − $167,651 and internal rate of return (IRR) of 11.75%), and an economically viable 100-TPA facility (with a ten-year projected cumulative cash flow of $3,176,750; NPV of $522,200 and IRR of 21.03%). Sensitivity analysis highlighted that the greatest gains to be realised in improving profitability were those associated with increasing the productive capacity of the facility, increasing the sale price of the product, and decreasing the capital costs of RAS facilities. Contradictions between the results from the present study to similar studies clearly highlight a need for further economic analyses of commercial RAS facilities, using commercial data sets and standard economic analysis procedures.

Current status of farming practices of striped catfish, Pangasianodon hypophthalmus in the Mekong Delta, Vietnam

Aquaculture of catfish, Pangasianodon hypophthalmus (Sauvage), locally known as “ca tra”, and commonly referred to as striped catfish, river catfish and sutchi catfish, in Vietnam, having recorded a production of 683,000 tonnes in 2007, valued at about 645 million US$ is one of the largest single species based farming system, restricted to a small geographical area, in the world. The product is almost totally exported to over 100 countries as frozen fillets, as an acceptable alternative to white fish. Catfish is farmed mostly in earthen ponds, up to 4 m deep, in nine provinces in the Mekong Delta in South Vietnam. The results of the grow-out system of catfish farming in the Mekong Delta from a survey of 89 farms are presented. The farm size ranged from 0.2 to 30 ha with a mean of 4.09 ha. The frequency distribution of the yield in tonne/ha/crop and tonne/ML/crop corresponded to a normal distribution curve, where 75% of the farms yielded 300 tonnes/ha/crop or more. It was found that the yield per crop was significantly correlated (p < 0.05) to stocking density, pond depth and volume but not to pond surface area. Yields per crop was significantly different (p < 0.05) between upper and lower provinces of the Mekong Delta and water source (river versus channels), amongst others. It was evident that diseases and/or symptoms were observed to occur mostly in accordance with the onset of rains. In this paper the history of the catfish farming in the Mekong Delta is briefly traced, and current harvesting and marketing procedures as well as pertinent social elements of the farming community are dealt with.

Event effectiveness : analysing the perceptions of key stakeholders of the Lexmark Indy 300/champ car event, Gold Coast.

The present study assessed the perceptions of the Lexmark Indy 300/Champ Car Event’s key stakeholders namely, spectators, volunteers and paid workers, as part of an evaluation tool for its managers. We developed a model, which included visible, interaction and management elements that we proposed influenced the perceptions and experiences of stakeholders relating to the event effectiveness, strengths, weaknesses and improvements. Specifically, we used a modified version of Preble’s (2005) six-step multi-stakeholder assessment approach to examining the perceived overall effectiveness of the event. Fifty stakeholder interviews were conducted on-site and their opinions were content analysed. The key findings of the study were that the majority of the stakeholders perceived the event to be effective. Spectators perceived the strengths to be interaction components, and weaknesses and improvements to be visible elements such as track layout. Volunteers perceived strengths to be management related, but also noted that these were weaknesses and needed improvement. Lastly, Paid workers perceived interaction elements to be both strengths and weaknesses, and suggested that management elements could be improved. Important implications for similar motoring events were suggested.

An exploration of the motivation to attend for spectators of the Lexmark Indy 300 champ car event, Gold Coast

The perceptions of spectators (N = 36) at the Lexmark Indy 300 Champ Car event were assessed via qualitative methods to evaluate their internal and external motivations to attend. The most common reason to attend was the atmosphere that the event created, and entertainment. Other reasons included the race, enjoying the company of friends, and group affiliation. The characteristics of the majority of attendees were predominantly male, 26 to 35 years old, from Queensland, who earned around AUD$50,000 to $75,000 per annum. The findings of the study have implications for sport marketers who wish to communicate to these individuals.

An exploration of the motivation to attend for spectators of the Lexmark Indy 300 champ car event, Gold Coast

The perceptions of spectators (N = 36) at the Lexmark Indy 300 Champ Car event were assessed via qualitative methods to evaluate their internal and external motivations to attend. The characteristics of the majority of attendees who were interviewed for this study were predominantly male, 26–35 years old, from Queensland, and who earned around AUD$50,000–75,000 per annum. The most common reason to attend was the atmosphere that the event created, in particular, the entertainment options. Other reasons included watching the race, the location, living nearby, attending with friends or family and interacting and socializing with other people who also attend. The findings revealed that participants attended to escape every day life, or that they were a ‘true fan’ of the motorsport. The findings of the study have implications for sport marketers who wish to communicate to those individuals in more targeted approaches for a more efficient and effective impact.

A prescrição das pretensões de reparação dos danos morais decorrentes de acidente de trabalho

O presente estudo tem por escopo analisar qual a prescrição aplicável às lides que versam sobre danos morais oriundos do acidente do trabalho ou doença ocupacional. Durante muito tempo prevaleceu o entendimento de que a Justiça Comum era competente para apreciar as demandas desta natureza, porém com o advento da Emenda Constitucional 45/05 transferiu-se esta competência para Justiça do Trabalho. Esta mudança foi causa da antinomia noticiada acima, ou seja, sendo competente a Justiça do Trabalho qual o prazo prescricional deve ser aplicada ao caso? Civil ou trabalhista? Assim, primeiramente, perquiriu-se os institutos do dano moral e da prescrição formulando os delineamentos básicos que subsidiaram a análise da problemática. Feito o esboço destes institutos, seguiu-se com o enfrentamento da questão e, com base nas regras de interpretação e integração do Direito, foram verificados os argumentos tanto da corrente civil como da trabalhista e os seus desdobramentos. Esclarecidas as teses, concluiu-se que a prescrição aplicável é a trabalhista visto que não há como se desvincular a regra de prescrição da relação jurídica da qual a pretensão decorre, no caso a relação de trabalho.

A construção de sentidos diante de um acidente ambiental: administração pública e sociedade contando estórias

As relações entre empresas e comunidade representam antigo objeto de estudo, sendo que, nas últimas três décadas, tem sido propugnado que existiria a responsabilidade social para com os interessados pela ação corporativa. Esta tese avaliou como ocorre a relação entre a organização econômica e as demais organizações intervenientes no espaço local em uma situação de crise, com o objetivo de desnudar as motivações mais estruturantes dos atores sociais. Para tanto, optou-se pela análise de um acidente ambiental ocorrido na cidade de São Paulo, no qual representantes da administração pública e da sociedade interagiram. A metodologia da pesquisa consistiu no olhar sobre as estratégias comunicativas, recorrendo-se à perspectiva da construção de sentidos (sensemaking) empreendida pelos envolvidos, tomando como apoio central o aporte conceitual de Karl Weick. Em primeiro lugar, realizou-se a revisão das abordagens da teoria organizacional que têm sido utilizadas, privilegiando o construto da Man Made Disaster, idealizado por Brian Turner em 1976, em razão de proporcionar visão abrangente dos fenômenos associados aos desastres. Na sequência, o evolver do acidente foi detalhado, com a intenção de situar o cenário em que o enredo se deu. Com esse anteparo, os discursos registrados nas comissões parlamentares de inquérito, criadas para investigar o problema, foram classificados segundo código documental elaborado a partir da revisão bibliográfica e da natureza do estudo de caso em foco. Concluiu-se que a estratégia de responsabilização (blaming), que impera nesse tipo de situação, não foi superada, o que seria requerido para a transformação no status quo dos atores sociais.
