    Economic Evaluation of Biotechnological Progress: The effect of changing management behavior

    Get PDF
    The paper assesses the welfare effects of biotechnological progress, as exemplified by tree improvements, using a partial equilibrium model. Timber demand is assumed to be stochastic and the distributions of the coefficients of the demand function are known. Assuming that timber supply is a log-linear function of timber price and forest inventory, we determine the coefficients of the supply function by maximizing the expected present value of the total surplus of timber production, both in the presence and in the absence of genetically improved regeneration materials. The supply functions are then used to estimate the expected present values of the total surplus in different cases through simulation. These estimates enable us to assess the direct effect and the total effect of the genetically improved regeneration materials on the expected present value of the total surplus. By taking the difference between these two effects, we obtain an estimate of the effect of changing harvest behavior induced by the use of genetically improved regeneration materials in forestry. The main results of the study are (1) the presence of genetically improved regeneration materials has significant impacts on the aggregate timber supply function; (2) application of genetically improved regeneration materials leads to a significant increase in the expected present value of the total surplus; (3) a considerable proportion of the welfare gain results from the change in timber harvest behavior; and (4) the use of genetically improved regeneration materials reduces the profits of timber production.timber market model; tree improvement; optimal harvesting decision; timber supply

    Robust Multi-Objective Sustainable Reverse Supply Chain Planning: An Application in the Steel Industry

    Get PDF
    In the design of the supply chain, the use of the returned products and their recycling in the production and consumption network is called reverse logistics. The proposed model aims to optimize the flow of materials in the supply chain network (SCN), and determine the amount and location of facilities and the planning of transportation in conditions of demand uncertainty. Thus, maximizing the total profit of operation, minimizing adverse environmental effects, and maximizing customer and supplier service levels have been considered as the main objectives. Accordingly, finding symmetry (balance) among the profit of operation, the environmental effects and customer and supplier service levels is considered in this research. To deal with the uncertainty of the model, scenario-based robust planning is employed alongside a meta-heuristic algorithm (NSGA-II) to solve the model with actual data from a case study of the steel industry in Iran. The results obtained from the model, solving and validating, compared with actual data indicated that the model could optimize the objectives seamlessly and determine the amount and location of the necessary facilities for the steel industry more appropriately.This article belongs to the Special Issue Uncertain Multi-Criteria Optimization Problem

    Manager's degree of JIT involvement, locus of control and managerial performance

    Get PDF
    The competitive global environment has lead many firms into adopting practices that focus on eliminating inefficiencies across the enterprise and its supply chain. The Just-in-Time philosophy is one such practice, however, research has predominantly focused on its technical features and on organisational variables, with surprising little research at the individual level. This paper examines JIT at an individual level and argues that the manager’s locus of control orientation would interact with their degree of JIT involvement to affect managerial performance. The results of a survey of 60 managers employing JIT, demonstrate that an increased degree of JIT involvement leads to a more positive effect on managerial performance for internal locus of control managers than for external locus of control managers

    Predicting Whole Forest Structure, Primary Productivity, and Biomass Density From Maximum Tree Size and Resource Limitations

    Get PDF
    In the face of uncertain biological response to climate change and the many critiques concerning model complexity it is increasingly important to develop predictive mechanistic frameworks that capture the dominant features of ecological communities and their dependencies on environmental factors. This is particularly important for critical global processes such as biomass changes, carbon export, and biogenic climate feedback. Past efforts have successfully understood a broad spectrum of plant and community traits across a range of biological diversity and body size, including tree size distributions and maximum tree height, from mechanical, hydrodynamic, and resource constraints. Recently it was shown that global scaling relationships for net primary productivity are correlated with local meteorology and the overall biomass density within a forest. Along with previous efforts, this highlights the connection between widely observed allometric relationships and predictive ecology. An emerging goal of ecological theory is to gain maximum predictive power with the least number of parameters. Here we show that the explicit dependence of such critical quantities can be systematically predicted knowing just the size of the largest tree. This is supported by data showing that forests converge to our predictions as they mature. Since maximum tree size can be calculated from local meteorology this provides a general framework for predicting the generic structure of forests from local environmental parameters thereby addressing a range of critical Earth-system questions.Comment: 26 pages, 4 figures, 1 Tabl

    Effective sourcing strategies for perishable product supply chains

    Get PDF
    Purpose – The purpose of this paper is to assess whether an existing sourcing strategy can effectively supply products of appropriate quality with acceptable levels of product waste if applied to an international perishable product supply chain. The authors also analyse whether the effectiveness of this sourcing strategy can be improved by including costs for expected shelf life losses while generating order policies. Design/methodology/approach – The performance of sourcing strategies is examined in a prototype international strawberry supply chain. Appropriate order policies were determined using parameters both with and without costs for expected shelf life losses. Shelf life losses during transport and storage were predicted using microbiological growth models. The performance of the resulting policies was assessed using a hybrid discrete event chain simulation model that includes continuous quality decay. Findings – The study's findings reveal that the order policies obtained with standard cost parameters result in poor product quality and large amounts of product waste. Also, including costs for expected shelf life losses in sourcing strategies significantly reduces product waste and improves product quality, although transportation costs rise. Practical implications – The study shows that in perishable product supply chain design a trade-off should be made between transportation costs, shortage costs, inventory costs, product waste, and expected shelf life losses. Originality/value – By presenting a generically applicable methodology for perishable product supply chain design, the authors contribute to research and practice efforts to reduce food waste. Furthermore, product quality information is included in supply chain network design, a research area that is still in its infancy

    A selected organisation provides hair dressing services and hair products to customers. The aim of this report is to analyse how the small hair salon could improve their marketing communication strategies in order to attract more customers and enhance the relationship between customers and the organisation. The approach to collecting information was to use a questionnaire with 50 participants, to gather primary information and to conduct a secondary research study. The result of this research was to decide that the role of a successful marketing communication strategy is to attract the customer to consume. In order to make the marketing communication strategy successful, it needs to choose a suitable channel that enables it to connect with the customer. New media is an effective channel that can promote the business to the customer and interact with them. New media is also suitable for a small business to use. A recommendation for the organisation is they create their own website page, Facebook page, YouTube video and WeChat group to promote themselves and interact with customers. Those channels are popular in New Zealand, with a high number of active users. Most the organisation customers like to use those channels too, so if the organisation applies those channels to their marketing communication strategy they will be able to attract customers and persuade them to consume more products

    Small business preference for software package

    Until late 2016, the majority of small business uses QuickBooks and Excel to do their accounting work. However, the functions of these accounting tools are insufficient, and also the demands of companies are increasing. It has become inefficient and antiquated to use the software. A small business looked for new accounting software, but found that choosing an accounting software system is not straightforward, as every software package consists of different functions for users. The aim of this research was to analyse small business’ perceptions and preferences for accounting software systems in New Zealand. This is followed by an analysis of why users might want to replace their previous accounting software systems. In addition, the requirements for selecting accounting software were analysed. The main method used was qualitative research. Three people were interviewed regarding the reason for replacing their previous accounting software system. The first interviewee had not changed their accounting software system previously, but their reason for replacing their current accounting software system was that their previous accounting software system lacked the functionality he wanted. The second interviewee said e she disliked that the system frequently crashed and that it lacked the features she wanted. The reason why the last interviewee changed her previous accounting software system was that MYOB system could not improve her work efficiency

    Nowadays online shopping is getting more and more popular in China. However, opportunities and challenges are coexisting, and the growth of e-commerce is also inevitable. In e-commerce online, trust has become a significant factor hindering development. A New Zealand organisation faces a lot of competitors. In order to increase its market share and remain competitive in the market, the organisation needs to have more loyal customers who repeatedly purchase their products. Therefore, the organisation should find an appropriate way to form or create trust with customers, to retain them. This research investigates how trust has been created in an online environment between an organisation and its customers. A qualitative method was adopted in this research and data collected using semi-structured interviews. The collected data was analysed adopting a thematic analysis method. The research findings show that a two-way communication system is the core factor in forming trust in the online environment. This research suggests that the organisation should consider two-way communication seriously, and develop that as a useful tool to build trust between them and customers; not just as a communication tool but as a tool for trust formation

    Examining the implications of the anti-money laundering and countering financing of Terrorism Act 2009 on New Zealand accounting firms

    Money laundering is the act of introducing illicitly gained funds into the economy to assist in concealing their origin. On October 1 2018, it became mandatory for most New Zealand accounting firms to comply with the Anti-Money Laundering and Countering Financing of Terrorism Act 2009. The purpose of this act is to help detect and deter money laundering within New Zealand. The AML/CFT Act creates additional requirements for accounting firms and has severe penalties for non-compliance. This led to the research question of ‘What are the implications of the AML/CFT Act 2009 on New Zealand Accounting firms?’ For this research, interviews were conducted with accounting firms to help identify the costs and implications associated with the AML/CFT requirements. The results revealed that despite the October 1 deadline, accounting firms are still implementing programs. The new requirements were unclear and underestimated by firms. Large money and time costs were reported by all the interview participants and they all feel that the new requirements are excessive. As the AML/CFT Act is still new, it would be beneficial to explore further research in the future that examines the actual impact of maintaining the AML/CFT programs

    The purpose of this research is to find competitive advantages for an organisation and prepare a long-term strategic planning for the SME. In a New Zealand context, small business enterprises play vital roles in business and the economic sector. However, most small business do not have specific competitive advantage and long-term strategies to compete in the market. Both qualitative and quantitative approaches have been used as mixed method research. Interviews and surveys have been done. Using those methods, researchers are intended to use the most effective implementation methodology to find out the best solution to the problem and cause of a SME. Location and customer satisfaction have been identified as the prime factors for the firm to run the business successfully. The business has been operating smoothly without using any further strategies to compete in the market. Recommendations involve pricing, advertising and stock management
