Optimal control problems from second-order difference equations

We examine solutions x?l_∞(Rⁿ) of the equations $\text{F}{}_{\mathrm{t}}\text{(}\text{x}{}_{\mathrm{t?1}}\text{,}\text{x}{}_{\mathrm{t}}\text{,}\text{x}{}_{\mathrm{t+1}}\text{) = 0}$ and derive conditions for the existence of objective functions G_t so that $\text{x}$ solves max_x?l∞ΣG_t(x_t, x_t+1). We specialize the conditions to time autonomous equations and apply them to a competitive industry in temporary equilibrium. The objective function in the example is of the cost-benefit form: consumer surplus minus opportunity cost of labor minus industry-wide cost of investment.     

The perceived effects of holiday‐taking upon the health and wellbeing of patients treated for cancer

The role that holidays play within health and wellbeing has been addressed infrequently within academic research. Much of the work that does exist has tended to focus upon illnesses or health complaints arising as a consequence of travel. Any beneficial health effects of travel largely have been neglected. This paper reports the empirical findings of a qualitative study conducted to determine the perceived effects of holiday‐taking upon the health and wellbeing of a group of cancer patients, a population ignored by the tourism community. Four perceived effects are identified relating to personal health, social effectiveness, personal identity and regaining independence, and the implications of these findings discussed.

IEEE 802.11s and the Philosophers' problem

IEEE 802.11s is the task group in the IEEE that is in the process of standardizing wireless mesh networks. A hot topic in this standardization effort concerns the need for additional medium access functionality beyond the basic IEEE 802.11 carrier sense multiple access with collision avoidance (CSMA/CA). In this paper, we discuss the connection between CSMA/CA and Dijkstra's classical Philosophers' problem, and its implications for the debate inside IEEE 802.11s. In an alternative view of this paper, we state some new mathematical models, theorems and conjectures related to the Philosophers' problem.     

Teens' consumer interaction styles: the impact of assertive and aggressive behaviour on attitudes towards marketing practices

Over half‐billion global teens between the ages of 13 and 18 years represent a dynamic opportunity for marketers who wish to grow their businesses and build consumer loyalty. Consumer interaction styles are the consistent behaviour patterns that individuals employ in transactions or exchanges in the marketplace. Assertiveness and aggressiveness represent two distinct interaction styles that enable individuals to achieve a desired outcome. Because teen consumers are an important consumer segment and subscribe to the notion that their voices must be heard, understanding their interaction styles is necessary for businesses and marketers. The purpose of this study was to examine teens' consumer interaction styles according to specific demographic and lifestyle characteristics and investigate the impact of assertive and aggressive interaction styles on attitudes towards marketing practices (i.e. product, retailing, advertising, and pricing). Data were collected from a US teen sample (n = 467) at both rural and urban high schools. Independent t‐tests compared the propensity of teens' assertive and aggressive consumer interaction styles according to specific demographic and lifestyle characteristics. Structural Equation Modeling using AMOS 6.0 program was performed to test the hypothesized relationships. Results indicated that an assertive interaction style was pervasive among US teen consumers, while the aggressive interaction style had disparities according to unique demographic and lifestyle characteristics. Assertive and aggressive interaction styles demonstrated negative influences on teen consumers' attitudes towards products and retailing practices. By interpreting the negative impact of teens' assertive and aggressive consumer interaction styles, marketers can develop effective strategies that appeal to this demanding consumer.     

The Effects of Government size on Economic Performance: a Quantitative Assessment of a Budget Reduction

A question featuring prominently in policy debates over the last few years is whether Australia can gain from having smaller government. Proponents have stressed beneficial impacts on the supply side of the economy; opponents have stressed the deflationary impact from possible reductions in demand. This article provides a quantitative assessment of this essentially empirical question, namely, whether supply or demand responses would dominate. It suggests that over the short term, demand contraction may be important. In the longer term, increased incentives can expand Australia's productive capacity, although incentives to work longer appear less important than incentives created for capital accumulation. But the longer term expansion may be crucially dependent on foreign investor acquiescence to increased involvement in the Australian economy.     

Brand orientation in charity organisations: qualitative research into key charity sectors

The study explores, through qualitative research, levels of brand orientation in large, medium and small‐sized charity organisations where brand orientation refers to the extent to which the organisation regards itself as a brand. The results indicate that charity managers are largely endorsing the conversion from charity organisation to charity brand. Brand status was seen to offer a shorthand communication of what the charity organisation did, its cause, and what it represented, its values. Significantly, it was also seen to fulfil organisational objectives such as raising awareness, building trust, fundraising and parliamentary lobbying, with a more focused and more consistent communication of what the organisation stood for. Strategically, however, charity organisations were not making the best use of their brands. It was suggested, for instance, that more sophisticated targeting of key donor segments with research‐based, tailored messages, might help reverse the trend of declining donor numbers. Overall, however, the study provides much evidence of brand orientation in the charity sector with most charity managers clearly wedded to the concept of putting the brand at the heart of the organisation. The charities that enjoyed a full commitment to the branding process from all their stakeholders were best placed to reap the benefits of charity brand status.

Consumer vulnerability and exclusion: A study of carers in the tourism marketplace

Abstract

Carers – a growing, multidimensional, context-specific, yet transient community (three in five of the population during a lifetime) – have been largely neglected in the marketing literature. Focusing upon the impediments to tourism participation this consumer group faces, the paper explores issues of carer engagement, consumer vulnerability, and societal exclusion from the perspective of two carer groups: senior carers and cancer carers. Conclusions reached demonstrate how challenging many carers find tourism-marketplace engagement and confirm carers can indeed be considered as vulnerable consumers. They introduce us to a range of circumstances that prompt exclusion and call upon policy makers to recognise the existence of multiple categories of vulnerability in accommodating the needs of this consumer. A future research agenda is outlined. This argues for the need to review the wider implications of the findings beyond the geographical constraints of this study, and to explore also their application to other vulnerable consumers.
