Abstract
In this paper a new computer‐aided digital system for partial discharge (PD) measurements is presented. The system is able to collect a great number of data, up to a pulse repetition rate of 100kHz, during the acquisition phase, thus allowing an off‐line analysis of PD data. After a description of the instrument, some experimental tests performed on epoxy specimens are here presented in terms of amplitude, phase and energy resolved histograms. Finally, emphasis is given to the very interesting use of the instrument for pattern recognition techniques in the discrimination and classification of discharges in HV components.

Abstract
Purpose
The purpose of this study is to explore food producers' motivations and challenges whilst participating in short food supply chains (SFSCs). This paper compares findings with previous literature and investigates the topic in the context of producers' motivations.
Design/methodology/approach
The paper includes a literature review concerning producers' motivations to engage in SFSCs. A case study was designed to investigate motivations underlying producers' engagement in SFSCs, as well as the challenges that they face. Semi-structured interviews were conducted in a farmers' market located in Mexico. Thematic analysis is used to identify the principal issues for producers'. Propositions based on findings are presented.
Findings
Findings suggest that small, large, part-time and full-time producers are willing to engage with farmers' markets for diverse primary economic and non-economic motivations. Individual and collective challenges were also identified.
Originality/value
This research helps to explain producers' motivations and challenges within SFSCs in an under-researched context, namely a focus on producers' and in the Global South.

Abstract
Purpose
The purpose of this research is to analyse the upstream information distortion among the various members of the agro-food supply chain, regarding the consumers’ quality perceptions.
Design/methodology/approach
The study focused on the beef chain, which is one of the most active in quality management terms. The study involved different actors in the chain: consumers (402), retailers (98), agro-industrials (40) and cattle farmers (84).
Findings
The results demonstrated that the more the upstream agents move away from consumers, the more the information becomes distorted. The research also highlighted that the greater the number of links in the chain, the more the consumer’s upstream information tends to be distorted.
Originality/value
The information flow is one of the important aspects on which the supply chain management focuses. This paper contributes to information flow research between different actors in the supply chain regarding product quality from the consumer perspective. Therefore, for the members of the supply chain, this research represents the potential to direct management’s value-added activities towards what consumers value the most.
