Supply chain operations in the presence of a spot market: a review with discussion

Abstract: We survey the recent literature on the use of spot market operations to manage procurement in supply chains We present results in two categories: work that deals with optimal procurement strategies and work related to the valuation of procurement contracts As an example of the latter, we provide new results on valuation of a supply contract with abandonment option Based on our review, we also discuss the scope for doing further work

Why do people lose their friends after a stroke

Abstract: Background: It is well-known that people lose friends after a stroke; what is less well understood is why this occurs. Aims: This study explored why people lose contact with their friends, and whether there are any protective factors. It also examined how friendship loss and change is perceived by the individual. Methods and Procedures: Participants with a first stroke were recruited from one acute stroke unit in the UK. In-depth qualitative interviews took place between 8 and 15 months post stroke. Outcomes and Results: 29 participants were recruited of whom 10 had aphasia. The main reasons given for losing friends were: loss of shared activities, reduced energy levels, physical disability, aphasia, unhelpful responses of others, environmental barriers, and changing social desires. The subset of participants who experienced the most extensive loss of friends were those who described a sense that they were ‘closing in’ on themselves leading to a withdrawal from social contact and a new preference for meeting only close friends and family. Those with aphasia experienced the most hurtful negative responses from others and found it more difficult to retain their friends unless they had strong supportive friendship patterns prior to the stroke. The factors which helped to protect friendships included: having a shared history, friends who showed concern, who lived locally, where the friendship was not activity-based, and where the participant had a ‘friends-based’ social network prior to the stroke. Conclusions and Implications: Given the link between depression and loss of friends post stroke, supporting an individual in maintaining a social network is likely to be beneficial. For intervention to be effective, however, it may need to take into account not only the impact of new physical and language disabilities, but also changing social desires.

Sales promotions and food consumption

Abstract: Sales promotions are widely used to market food to adults, children, and youth. Yet, in contrast to advertising, practically no attention has been paid to their impacts on dietary behaviors, or to how they may be used more effectively to promote healthy eating. This review explores the available literature on the subject. The objective is to identify if and what literature exists, examine the nature of this literature, and analyze what can be learned from it about the effects of sales promotions on food consumption. The review finds that while sales promotions lead to significant sales increases over the short-term, this does not necessarily lead to changes in food-consumption patterns. Nevertheless, there is evidence from econometric modeling studies indicating that sales promotions can influence consumption patterns by influencing the purchasing choices of consumers and encouraging them to eat more. These effects depend on the characteristics of the food product, sales promotion, and consumer. The complexity of the effects means that sales promotions aiming to encourage consumption of nutritious foods need to be carefully designed. These conclusions are based on studies that use mainly sales data as a proxy for dietary intake. The nutrition (and economics) research communities should add to this existing body of research to provide evidence on the impact of sales promotions on dietary intake and related behaviors. This would help support the development of a sales promotion environment conducive to healthy eating.

Ordering Top Pay: Interpreting the Signals*

Abstract:  Boardroom reward continues to attract controversy, despite the structural changes in corporate governance arrangements over the past decade. This study responds to Pettigrew’s (1992) call to eschew over-ambitious attempts to demonstrate causality in the area of executive management and firm performance, in favour of redressing the overwhelmingly prescriptive bias in the literature. A simple but important task is to ‘begin to provide some basic descriptive findings about boards and their directors’, and open up ‘the black box of board behaviour’ ‐ in this case, that of board remuneration committees. Interpretations of comparative market signals play a part in deliberations between the leading actors responsible for determining executive directors’ salary, bonuses and other emoluments. But the position is more deeply textured than the reified influence of (global) market forces sometimes implied in the normative literature. The study reported, based on qualitative interviews, taps in to the nuances of decision taking in respect of boardroom reward management, including remuneration committee members’ reactions to corporate governance reforms. Such initiatives locate non-executive directors in the role of intermediaries in the principal-agent relationship, explicitly assigned to resolve the conflict of interest inherent in boardroom remuneration systems, while simultaneously they are expected to play a team role as board members responsible for the overall strategy and operation of the company. The study is indicative: an attempt to open up research questions around the context and process of boardroom reward management that earlier analyses may have ignored or overlooked.
