Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

This article posits that a more rigorous enforcement of the Constitutional Doctrine of Non-delegation would prevent many of the problems that have been identified with benefit–cost analysis. In particular, a rigorous application would prevent administrative agencies from using benefit–cost analysis as a screen to make policy decisions that the agency otherwise wishes to occur. Though the US Courts might have some difficulty in enforcing this notion, it is possible to do, and would greatly help the benefit–cost process, by regulating it to its proper place in an administrative system.

Cost-benefit (C/B) analysis helps to determine the economic feasibility of business software investments. Research literature and published practices do not recognize substantial software maintenance costs in C/B analysis. Current analyses emphasize the benefits of an initial investment but do not consider the recurring benefits of each enhancement during the software lifecycle. Such analyses could lead to incorrect investment decisions and lost business opportunities. This article aims to review current research on software lifecycle costs and develop a theoretically sound C/B analysis.

This article reviews current C/B analyses and discusses their shortcomings in treating the significant recurring maintenance costs. It analyzes the findings of various studies on software maintenance and synthesizes these findings to identify the nature of various maintenance costs and their benefits. Based on the synthesis, it theorizes various cost and benefit elements for inclusion in a revised C/B analysis.

This article identifies each recurring maintenance cost relevant to C/B analysis. It also identifies recurring benefits from each enhancement that hitherto have been omitted. Finally, this article discusses how these costs and benefits should be treated in the revised C/Bs analysis.

This is a conceptual paper proposing a new C/B analysis and requires an empirical validation.

This article provides a revision of the C/B analysis that is long overdue. It will help to justify a software investment correctly, rank software projects that compete for limited funds and help create a sound software project portfolio. Since 20% of software products may incur 80% of software investment, this analysis will help to make correct software investments and avoid lost business opportunities. This article also describes a practical method to use the revised C/B analysis.

RECENT YEARS have witnessed the proliferation of applications of cost‐benefit analysis to public sector expenditure. Cost‐benefit analysis is a method of decision‐making which seeks to quantify the benefits that are obtainable from a given course of action, to express them in financial terms (or in terms of financial equivalents) and then to deduct the estimated social and financial costs so that the results of the course of action may be assessed, valued and expressed in monetary terms. Quantification of actual financial costs and benefits poses no difficulties, but it has been shown elsewhere that the quantification of social costs and benefits often poses considerable problems. Some social benefits, such as the value of time‐saving, can be quantified reasonably successfully (using, for example, financial equivalents of time saved in terms of average wages or average salaries of the individuals concerned), but others, such as the measurement of alleviation of suffering or the assessment of degrees of incapability in nursing care, have no adequate financial equivalents.

An updated version of the original (1985) text, the book covers all aspects of marketing and selling bank services: the role of marketing; behaviour of customers; intelligence, planning and organisation; product decisions; promotion decisions; place decisions; price decisions; achieving sales. Application questions help to focus the readers' minds on key issues affecting practice.
