Cost implications of improving food safety in the Dutch dairy chain

This paper examines control measures for improving food safetyin the dairy chain, using an integer linear programming model.The chain includes feed (compound feed production and delivery),farm (dairy farm) and dairy processing (transport and processingof raw milk, delivery of pasteurised milk) blocks. Results showthat 65 per cent of the maximum possible food safety improvementcan be achieved at relatively low extra cost per ton of milk(4.27), fairly evenly distributed across the blocks. Highersafety levels can be attained by increasing the farm block'scontribution, but at much higher extra cost (44.37 for the maximumattainable).     

Price and Volatility Transmission and Market Power in the German Fresh Pork Supply Chain

We investigate the relationship between the transmission of price volatility and market power in the German fresh pork supply chain. We use a theoretical model underpinning this relationship followed by an empirical application that uses monthly farm, slaughterhouse and retail pork price data for the period 2000–2011. We examine both the relationships of market power with price level transmission and price volatility transmission in the chain. We use a vector error correction model and least squares regressions to analyse price transmission and price volatility transmissions, respectively. Results show that retail market power limited both types of transmissions. Competition inducing policy measures coupled with measures that support price risk management initiatives of chain actors are suggested.     

Technical efficiency of high technology medicine

Intensive care units (ICUs) are classic examples of high technology medicine. The ICU has become an essential step in the clinical management of patients passing through a phase of critical illness, However, the costs are extremely h9gh (1% of GNP in the USA), whereas it has not ben adeqyately demonstrated that routine admission to intensive care is associated with an increase in survival rate and a decrease in morbidity. Consequently, intensive care is a logical arena in which to encourage more efficient use. The paper focuses on determinates of the technical efficiency of the ICU. Technical efficiency can only be ensured when the ICU is conceived as a responsibility centre where inputs, throughputs and outputs are measured. The reaponsbility centre in characterized by management control, which is dependent on reliable information regarding incentives and constraints of ICU performance. On the basis of the medical and economic literature, conjectures are made on determinants of ICU performance. In addition, some results are presented of a feasibility study commissional by the Netherlands Ministry of Health.     

Women and economic development

This article relates some experiences of local authority interventions in Wolverhampton which have contributed to effective economic development work with women. The intention is to highlight approaches and actions which we believe need to be incorporated into local authority economic strategy in order to address women's needs. We also aim to identify certain limiting factors arising from the national context. The paper is based on work undertaken by the authors whilst working for Wolverhampton Council.     

What counts as a reasonable extent? – a systems approach for understanding fire safety in Sweden

Swedish legislation requires that any owner or user of a building maintain a reasonable level of fire protection measures to ensure the safety of all people located in the building. If a building, in the wake of a fire, in court is determined not to have had a reasonable fire protection, the blame will likewise be assigned to the building owner or user. Using the perspective of risk governance, this study aims at analysing how regulation and stakeholders interact to maintain a specific level of fire protection in hotels. The focus is on identifying problems and frictions that have emerged from the complex relationships, and differences of interests, between the different stakeholders. Based on a stakeholder analysis, 11 respondents were selected for an interview study. The main problems identified in the analysis are that there are ambiguities for the individual hotel owner to know whether her or his fire protection measures are reasonable according to the law, that the system has emerged without clear political goals, problems related to the process of local supervision, that the ambiguous situation gives rise to opportunities of other stakeholders to claim the definition of what counts as a reasonable extent, and the ethical problems associated with convicting a single individual for failure in a complex multi-actor system.     

Ample Consumption Period Available Until Use-by Dates: A Potential Marketing Position for Store Brands

SUMMARY

Store brands, when moving upscale, inevitably relinquish their value for money appeal and therefore require some quality dimension to compete. This article is proposing that the promise of “generous” use-by dates as a surrogate for quality could be considered as a positioning plank to promote store brands as alternatives to manufactured brands. Logit analysis is employed to explain shoppers' perceptions and responses to use-by dates, of products that they regularly buy, and of alternative products that they have never bought before if the use-by dates of their regular items are perceived to be too short.     

Protecting software development projects against underestimation

When a project in progress has been seriously underestimated, it is essential to figure out how much additional effort is required to complete it within its original scope and delivery date. This article posits that project contingencies should be based on the amount it will take to recover from the underestimation, and not on the amount that would have been required had the project been adequately planned from the beginning, and that these funds should be administered at the portfolio level. A model to calculate the required funds is developed.     

The numbing effect of mortality salience in consumer settings

Nationwide Insurance and Johnnie Walker Scotch aired advertisements that encouraged people to contemplate death. What are the immediate emotional and perceptual outcomes of such advertisements? With five studies, thinking about death was found to attenuate emotional reactions and perceptions, a novel finding in the literature. This attenuation was observed with neural and self‐report measures along with retrospective and prospective assessments of emotion and is an outcome not yet investigated in mortality salience research. Contemplating death dampened people's expectations of emotion in a future consumption experience and diminished the attractiveness of the experience. Similarly, contemplating death affected backward‐looking assessments of emotion, for example, when nostalgic memories are brought to mind. Importantly, this dampening effect of mortality salience was replicated with advertisements that portrayed death‐related concepts and attenuated emotional reactions to subsequent advertisements.     

A note on the periodicities in the logistic analyses of growth processes

In real life growth processes there is always an intrinsic finite response time. This means that these systems do not respond instantaneously so that the logistic modeling of such processes should be formally described by a delayed logistic equation. This poses enormous difficulties to their time evolution modeling as there are no analytical solutions to the delayed logistic equation. In this paper we show that by performing a conventional Verhulst logistic modeling of the corresponding time series data, associated with a fine-coarse analysis of the resulting residuals, we can disclose the underlying periodicities due to the finite time response effects.     

Les Caisses Rurales Face à l'Union Monétaire: Une étude d'efficacité comparée

The authors analyze the economic efficiency of rural credit unions of large size compared to a group of credit unions. The methodology is based on the analysis of profitability, productivity and efficiency ratios and on the estimation of a Cobb–Douglas cost function. The evolution during the period 1989–1994 as well as the situation at the end of this period are examined. The same methodology is used to study the rural credit unions individually.
