Optimization Modeling for Logistics: Options and Implementations

Logistics optimization has significantly grown in popularity over the last few decades. Improvements in computing power, modeling software, and the willingness of companies to invest time in the modeling effort have allowed models that were once too unwieldy to solve to optimality to be solved quickly. This has led to a more wide‐spread recognition by logistics managers of the potential advantages of using optimization. The scope of logistics optimization in companies and organizations has expanded to address strategic, tactical, operational, and collaborative decision making. Spreadsheets, an analytical tool familiar to managers, have played a crucial role in the expanded modeling efforts of companies. Although optimization’s role in logistics has grown tremendously, there still are areas that remain to be explored that will allow it to achieve an even larger and more successful role in the management of companies. Additionally, there are some models that are still too large or too complex to currently solve to optimality, despite the advances in computing power and modeling/solving software.     

Wall Street and Vine: Hollywood's View of Business

American films have long presented a negative view of business. This article is the first comprehensive and in‐depth analysis of filmmakers' attitude toward business. It shows that it is not business that filmmakers dislike but rather the control of firms by profit‐maximizing capitalists. The article argues that this dislike stems from filmmakers' resentment of capitalists' constraints on their artistic vision. Filmmakers' portrayal of business is significant because films have persuasive power that tips the political balance toward business regulation. Copyright © 2012 John Wiley & Sons, Ltd.     

Operational planning and competitive strategies of male and female retailers

Interest in the managerial practices of females in business has increased over the past decade due to women's increased representation in business. Anecdotal evidence has suggested that women approach decision making differently from men. The purpose of this study is to determine if gender differences regarding managerial strategies exist in the retail setting. Targeted managerial strategies focused on short-term planning processes (personnel, financial, inventory and market planning) and competitive strategies in operation (differentiation, cost leadership and focus). In a sample of 459 retailers from a twelve-state region, MANOVA was used to determine if significant differences in managerial strategies existed between genders. The data on retail competitive strategies suggest that men and women more likely than male business owners to recognize in the importance of differentiation and focus as retail competitive strategies in their business operations. Gender differences were also found in the operational planning areas of market and inventory planning.     

Price competitiveness of tourism packages to Australia: Beyond the “Big Mac” index

One issue facing any country or region concerns its price competitiveness as a package tour destination. One method of measuring this is to use what in other contexts has been referred to as the Big Mac approach. The “Big Mac” is a simple product with ingredients in fixed proportions, whereas the tourism product is a very complex one comprising different components depending on tourist expenditure patterns. There is no equivalent tourism product offered across countries, as the nature of the product is tailored to the origin market, expenditure levels and the length of the trip involved. The key issue is that of how to standardize the products being compared, so as to determine their relative price competitiveness. A method of constructing price competitiveness indexes, developed by the authors, can be applied to develop measures of the price competitiveness of different tour packages. This paper has three aims: To set down the essence of the preferred approach to measuring price competitiveness, noting its advantages and limitations; to employ this approach to construct price competitiveness indexes for package tours to Australia from Japan and the USA; and to indicate areas for farther research into the price competitiveness of package tourism worldwide.     

Advertising and the seven sins of memory

A positive intention may be formed as a result of exposure to an advertisement, but if a memory malfunction interferes with that intention, the advertising will be ineffective.This paper considers the implications for advertisers of Daniel Schacter’s ‘seven sins of memory’: transcience, absent-mindedness, blocking, misattribution, suggestibility, bias and persistence. Each of the ‘sins’ is explained in detail and advice provided for advertisers on how to avoid these pitfalls.

Rhetoric, argument and impression management in hostile takeover defence documents

This exploratory study extends the analysis of narrative disclosures from routine reporting contexts such as annual reports and press releases to non-routine takeover documents where the financial consequences of narrative disclosures can be substantial. Rhetoric and argument in the form of impression management techniques in narrative disclosures are examined. Prior thematic content analysis methods for analysing good and bad news disclosures are adapted to the attacking and defensive themes in the defence documents of target companies subject to hostile takeover bids. The paper examines the incidence, extent and implications of impression management in ten hostile takeover defence documents issued by target companies listed on the London Stock Exchange between 1 January 2006 and 30 June 2008. Three impression management strategies – thematic, visual and rhetorical manipulation – are investigated using content analysis methodologies. The findings of the research indicate that thematic, visual and rhetorical manipulation is evident in hostile takeover defence documents. Attacking and defensive sentences were found to comprise the majority of the defence documents analysed. Such sentences exhibited varying degrees of visual and rhetorical emphasis, which served to award greater or lesser degrees of prominence to the information conveyed by target company management.While exploratory in nature, this paper concludes with suggestions for future more systematic research allowing for greater generalisations from the findings.     

Alcohol Advertising Controls in the 1990s

Public health campaigners have criticized the British system for the regulation of alcohol advertising, which relies on several distinct codes of practice governing different media. This paper looks at the options for change, in the light of the economic, political and technological factors that will influence the development of the UK's alcohol advertising policy in the 1990s. The available evidence on the costs and benefits of alternative policies is reviewed, drawing on the Addiction Research Centre's multi-disciplinary programme of work undertaken at the Universities of Hull and York. While there is some evidence that a ban on alcohol advertising would have a marginal effect on overall consumption, it is argued that legislative intervention is no longer feasible. Technological innovation and global pressures for deregulation have made it difficult for national governments to ban the advertising of any one product. At the same time, however, it is feared that commercial pressures resulting from the introduction of satellite broadcasting and the increased competition for advertising revenues could undermine the existing self-regulatory system and exert a downwards pressure on advertising standards. It is suggested that the way forward lies in developing a strong self-regulatory system throughout Europe.     

Two-stage adoption of different types of pollution prevention (P2) activities

Pollution prevention (P2) remains the key pollution reduction strategy in the US despite its limited success in improving environmental performance. To aid the targeting of policies to promote the types of P2 that achieve environmental goals, this study investigates the intricate nature of P2 adoption by (1) distinguishing among three types of P2: procedural changes, input and material changes and equipment and product changes, (2) disentangling the adoption decision into a binary and a count decision, and (3) analyzing benefit- and cost-related factors. Using a sample of facilities of S&P 500 firms, I employ NB hurdle models to analyze how facilities respond to these factors in making P2 adoption decisions. I find that facilities that have lower cost of adoption due to past P2 experience have higher likelihood of adoption and higher rates of adoption of all types of P2. However, those exposed to greater threat of enforcement action find limited scope for P2 in achieving environmental compliance objectives. Some regulatory threat variables even have a negative effect. Facilities also adopt P2 to enjoy market-related benefits: final good producers are more likely to adopt P2 that appeal to consumers (input and material changes), while intermediate good producers are more likely to adopt P2 that is valued by its supply chain (procedural changes). Community characteristics and other knowledge sources are not always positively associated with the likelihood of adoption nor with the rate of adoption.
