Group Structured Reasoning for Coalescing Group Decisions

In this paper we present the notion of structured reasoning through a model, called the Generic/Actual Argument Model (GAAM). The model which has been used as a computational representation for machine modelling of reasoning and for hybrid combinations of human and machine reasoning can be used as a coalescent framework for decision making. Whilst the notion of structuring reasoning is not new, structured reasoning is advanced as a technique where group consensus on reasoning structures at various levels can be used to facilitate the comprehension of complex reasoning particularly where there are multiple perspectives. For an issue, the approach provides a scaffolding structure for cognitive co-operation and a normative reasoning structure against which group participants can identify points of difference and points in common as well as the nature of the differences and similarities. Intra-group transparency characterized by the ability to recognise points in common and understand the nature of differences is important to the process of coalescing group decisions that carry maximum group support.     

The consequences of voluntary traceability system for supply chain relationships. An application of transaction cost economics

This paper analyses the effects of voluntary traceability on vertical relationships within food supply chains using a transaction cost perspective. The analysis makes reference to the Italian situation where the national standard organization has introduced a private standard for traceability that provides a higher degree of information associated with the individual product than the European mandatory traceability system. A survey was conducted by questionnaire to assess changes in transaction characteristics, costs and governance after the introduction of voluntary traceability. The sample represents all Italian firms applying this standard. Factorial and cluster analyses were applied to find the different reorganizations of transactions. The results highlight an increase in asset specificity and a decrease in the uncertainty level throughout the supply chains. The introduction of voluntary traceability shows increased vertical coordination for firms that previously used oral agreements and variation in transactions conditions for firms using contracts. Instead vertically integrated firms do not reveal any variation in the governance of transactions as they are already internally safeguarded.     

Do Nutrition Claims Matter to Consumers? An Empirical Analysis Considering European Requirements

EU Regulation 1924/2006 introduced a European legal framework for nutrition messages for food product labels. The study analyses consumer interest towards nutrition labelling and claims, and examines the information consumers consider important during their purchasing decisions, and the main characteristics of those consumers interested in nutrition claims and nutrition labelling use. A total of 1,025 northern Italian consumers were surveyed. We estimate one binary logit model to investigate the use of nutrition labelling, and seven other ordinal regression models to analyse consumer interest towards nutrition claims and labelling. Consumers who use nutrition labelling have characteristics different from those who use nutrition claims. Consumers using nutrition labelling show a marked interest in food safety concerns, use experts as their source of information and have specific dietary habits. For consumers concerned about nutrition claims, the survey shows significant links with attributes influencing purchasing behaviour, such as price, brand, certification, etc. Socio‐demographic characteristics are statistically significant and show a positive link with age, gender and a negative linkage with income.     

Shelf Life Date Extension of Fresh-Cut Salad: A Consumer Perspective

ABSTRACT

During the past decades, various technological applications relating to an extension of the shelf life of food products have been introduced. The adoption of such technologies in the fresh-cut salad sector is a key issue for the sustainable management of the supply chain. The aim of the study is to analyse consumers’ attitude towards fresh-cut salad with an extended shelf life date. The analysis was based on face-to-face interviews with 351 consumers living in Lombardy, one of the Italian provinces where the consumption of fresh-cut salad is high and characterized by good margins of development. Principal component factor analysis with varimax rotation was used as preliminary data preparation for market segmentation. Cluster analysis revealed the presence of three different consumers groups. Only the cluster of ‘favorable’ shows a positive attitude towards the extended shelf life date. Consumers grouped in the cluster of ‘skeptical’ associate such innovation to a low level of product freshness. The cluster of ‘mistrust’ reveals the presence of consumers with safety concerns towards the prolongation of the shelf life date. Such consumers do not reveal a high level of trust in processing firms and their related brands.
