The survey tool contained three main sections (Section I: Mechanisms for managing agri-food supply chains, Section II: Problems of managing agri-food supply chains, and Section III: Information about the interviewee and his business partners).
One interviewee clearly stated that partners "inspired me for new projects to study the variety in new productivity outcome measures" (RK).
In five interviews, a family member was present at some point — on request of the interviewee — (two daughters, three partners) and provided an occasional comment or answer to illustrate matters that participants found difficult to remember (for example, reason for participation).
Interviewees particularly believed partners would think better of them for telling them this way.
The potential interviewees were contacted by telephone by members of the consortium, an appointment was made for a personal interview, and in a few cases where the distance between the partner and the interviewee was great e.g. Argentina, a telephone interview was held.
However, the prospect of a long-term or permanent stay, most clearly expressed by interviewees with a non-Polish partner and children in the UK, can have a mobilizing effect driven by the perceived need to uphold and pass on Polish language and culture.
But the researchers did look at four possibilities: the sex of the interviewee, whether the person had a partner, whether there were children at home and employment status.
The numbers of interviewees per stakeholder group as well as the total number of interviewees for each country vary across partner countries due to different financial resources available to the research partners and to the availability of contacted stakeholders to take part in the study.
The patient may not know the name or contact details of partners as "one night stands" were common and one interviewee believed that less than 50% of partners would be reached (NGO).
Two groups of experts (interviewees and scorers) were selected from partner institutions of RCZI with the goal of providing inputs from different academic, policy, and sector perspectives (File S1).
