Planning for ecotourism in the protected area of Manesht and Ghelarang,Ilam Province,Iran

ABSTRACT

This paper reports a study of the Manesht- and Ghelarang-protected area in Iran. The study sought to identify ways in which sustainable tourism policies could be generated that aid the natural and human environments. From surveys and questionnaires completed by tourists, residents, and officials, an initial set of 10 areas of weakness, 9 strengths, and 6 opportunities were identified. Using these classifications combined with mapping techniques that included maps of topography and flora, a subsequent Technique for Order of Preference by Similarity to Ideal Solution analysis identified potential future policies that require infrastructure development and reinforced pro-environmental policies to address the problems currently being experienced.     

Cost-effectiveness of beef slaughterhouse decontamination measures in the Netherlands

The cost-effectiveness of seven decontamination measures to reduce Escherichia coli O157:H7 (VTEC)-contaminated carcass quarters in a typical Dutch dairy-beef industrial slaughterhouse were explored. To estimate the effectiveness a stochastic epidemiological-simulation model was used and to estimate the net cost a deterministic-economic model. The estimated baseline prevalence of daily-contaminated quarters was 9.16% (with a 90% confidence interval 4.40-13.10%). A reduction in the prevalence of VTEC-contaminated quarters to 2% using decontamination measures is achieved at costs of €0.20 to €0.50 per quarter, which is 16-40% of the net profit per carcass. A reduction to a prevalence of 1% will cost €0.50-€1.00 per quarter. Additional carcass trim and carcass steam-pasteurization are considered as the most cost-effective decontamination measures with costs of €16,340 and €20,243 per year to achieve a 1% prevalence reduction. Nevertheless, the lowest level of VTEC prevalence, less than 1%, is achieved using a set of measures that costs between €1.00 and €2.00 per quarter or, by implementing irradiation, which costs €4.65 per quarter.     

Estimation of trade elasticities in the presence of trade barriers, multinationals and imperfect competition

Recent research highlights the role that multinational trading companies may play in impeding price transmission. In markets characterised by imperfect competition, an estimate of the partial elasticity of demand may be of limited practical value if no account is taken of the reaction of competitors. In this paper, we demonstrate the potential for market structure to affect price transmission and trade elasticities, and challenge the presumption that only government intervention can impact upon price transmission, with examples supporting why theory would suggest otherwise.     

Product resource–capability complementarity,integration mechanisms,and first product advantage

The current study extends work on resource-based theory (RBT) by exploring resource—capability complementarity in a new context—that of new technology ventures' (NTVs) first product (FP) commercialization in India. This study examines the influence of marketing and technology resource–capability complementarity on FP positional advantages (differentiation and cost-efficiency) and their influence on first product performance (FPP). Furthermore, this study incorporates the influence of supplier integration (SI) mechanisms (in terms of knowledge sharing and co-commercialization) in the process of FP commercialization. The findings suggest that asset complementarities have a positive relation with FP positional advantages, in that both differentiation and cost-efficiency enhance an NTV's FPP, and that SI moderates the relationships between both marketing and technology R–C complementarity and FP positional advantages.     

Demand under product differentiation: an empirical analysis of the US wine market*

Oversupply has led to a number of perplexities for the Australian wine industry in recent times. When disaggregated from the industry level, however, the problem can be better described as a range of attribute‐specific disequilibria. To date, the solutions to this problem have predominantly revolved around supply‐side policies of reducing output through crop thinning or vine pulling. By contrast, this paper focuses on the demand side and argues that the disequilibria may be reduced by gaining a better understanding of the demand for Australian wine. A discrete choice model of product differentiation is used to estimate the demand for wine in Australia's second largest export market, the United States. Implications of the analysis are explored.     

Online Repurchasing: The Role of Information Disclosure,Hope, and Goal Attainment

The emergence of online purchasing has changed the relationship between consumers and brands. Our research focuses on online information disclosure and consumer hope in an online shopping environment. Two studies are undertaken to test the theoretically derived hypotheses. Study 1 evaluates the causal relationship between information disclosure and hope via an experiment in an online shopping context. Study 2 involves an online survey to test the nomological network presented in this research. The models identify the moderating effect of consumer product knowledge on online information disclosure and consumer hope. For academics, this research advances knowledge of how consumers' confidence in sharing personal information develops hope, consequently enabling them to attain their goals and repeat their purchases. For practitioners, it offers a better understanding of how investments are successful in aiding consumers to attain their goals and generate repeat purchase intentions in an online shopping environment.     

The theory of storage in the crude oil futures market,the role of financial conditions

This study examines the impacts of inventory and financial instability on the basis of the crude oil market. The results show that, first, the basis rises with inventory, and this effect is higher during low inventory regimes. This validates the theory of storage in the crude oil market. Second, the basis rises with financial instability, and this effect is higher during turbulent regimes. These results warn the oil market participants that, to make decisions based on the basis variation, traditionally known as a signal of scarcity or abundance, the underlying cause of the variation has to be considered.     

Incorporating location,routing and inventory decisions in supply chain network design

This paper for the first time presents a novel model to simultaneously optimize location, allocation, capacity, inventory, and routing decisions in a stochastic supply chain system. Each customer’s demand is uncertain and follows a normal distribution, and each distribution center maintains a certain amount of safety stock. To solve the model, first we present an exact solution method by casting the problem as a mixed integer convex program, and then we establish a heuristic method based on a hybridization of Tabu Search and Simulated Annealing. The results show that the proposed heuristic is considerably efficient and effective for a broad range of problem sizes.     

Simulating economic values of a genetic improvement program for Australian farmed saltwater crocodiles*

In genetic improvement programs, candidates for breeders are ranked by the profitability of their offspring, expressed as a weighted sum of the genetic gain from selection. In this paper, we estimate the economic values of a genetic improvement program for Australian farmed saltwater crocodiles. A bioeconomic profit function for a representative breeding pair is used to determine the optimal slaughter age following genetic improvement in each selection objective. The results indicate that estimated farm profitability increases by nearly $A111 for a 1‐week reduction in juvenile slaughter age, $A78 for a 1 per cent increase in the proportion of first‐grade skins produced, and $A33 for an increase in the number of viable hatchlings per clutch. The implications of the analysis for the Australian crocodile industry and the limitations of the research are explored.     

Reconstruction of past records

In this paper, the problem of reconstructing past records from the known values of future records is investigated. Different methods are applied when the underlying distributions are Exponential and Pareto, and several reconstructors are obtained and then compared. A data set representing the record values of average July temperatures in Neuenburg, Switzerland, is used to illustrate the proposed procedure in the Pareto case. The results may be used for studying the past epoch times of non-homogeneous Poisson process or the past failure times in a reliability problem when the repair policy is minimal repair. N.
