The purpose of this paper is to assess the reliability of questionnaires as a method of quantifying household food waste (FW), thus providing context regarding the validity of existing Italian estimates.

A total of 30 households were involved in a diary study that was conducted for one week. The participating households were first asked about their FW quantities in a questionnaire. Half of the households who filled their diaries properly were then audited through waste sorting analysis performed on their garbage. Non-parametric tests were used to test for differences in FW estimates between audited and non-audited households, as well as differences among estimates obtained through different quantification methodologies.

Edible FW was estimated to be 489 grams per week based on questionnaires, and 1,035 grams per week based on diaries. In the audited sub-sample of households, FW estimates were 334 grams per week based on questionnaires, 818 grams per week based on diaries and 1,058 grams per week based on waste sorting analysis.

Given the small sample size in the present study, future studies can utilize larger samples to assess whether the differences identified in estimates can be replicated. Future studies can also inquire into the behavioral biases that led consumers to underestimate their FW.

Results of the present study point against the use of questionnaires to quantify household FW, hence raising some doubt on the reliability of existent Italian estimates. Where waste sorting is unfeasible, the use of adjustment methods or diaries is suggested to better inform policies.

This study is one of the first on FW quantification that tests three different methodologies on the same sample, and is the first to do so in Italy, where estimates are still very poor.

Agri-food supply chains are facing a number of challenges, which cause inefficiencies resulting in the waste of natural and economic resources, and in negative environmental and social impacts. Food waste (FW) is a result of such inefficiencies and supply chain actors search for economically viable innovations to prevent and reduce it. This study aims to analyse the drivers and the barriers that affect the decision of supply chain operators to adopt innovations (technological – TI, organisational – OI and marketing – MI) to reduce FW.

The analysis was carried out using a four-step approach that included: a literature review to identify factors affecting the decision to adopt innovations; analysis of FW drivers and reduction possibilities along agri-food supply chains through innovations; mapping the results of Steps 1 and 2 and deriving conclusions regarding the factors affecting the adoption of innovations to reduce and prevent FW.

Results show that different types of innovations have a high potential in reducing and preventing FW along the supply chain; however, they still must be economically feasible to be adopted by decision makers in the food supply chain. TI, OI and MI are often interrelated and can trigger each other. When it comes to a combination of different types of innovation to reduce and prevent FW, a good example of combining TI, OI and MI may be observed in the retail sector in Europe. Here, innovative smartphone apps (TI) to promote the sale of products nearing their expiration dates (OI in terms of organising the sales differently and MI in terms of marketing it differently) were developed and adopted via different retailing channels, leading to the creation of a new business model.

This study analyses the drivers of FW generation together with the factors affecting the decision to adopt innovations to reduce it and provides solutions to supply chain operators to prevent and reduce FW through different types of innovations.

Literature has not systematically addressed innovations aiming at the reduction of FW yet. This paper provides a comprehensive literature review of the determinants of innovation adoption and offers a novel view on the problem of FW reduction by means of innovation, by linking factors affecting the decision to innovate with FW drivers.

The paper reflects on the role of knowledge artefacts in the patient-provider relationship across the organisational boundaries of the clinical setting. Drawing on the analysis of the diabetes logbook, the purpose of this paper is to illustrate the role of knowledge artefacts in a fragmented system of knowledge through the study of two distinct practices: “logbook compiling” and “consultation in the surgery”.

The theoretical framework of analysis is rooted in the tradition of practice-based studies which envisions knowledge as the emerging, precarious and socially constructed product of being involved in a practice. The paper follows a designed qualitative research, conducting semi-structured interviews, participant observation and artefact analysis.

The knowledge artefacts support different and partially irreducible forms of knowledge. Knowing-in-practice is accomplished by means of different activities which contribute to the reshaping of the knowledge artefact itself. The analysis of the “knowledge artefact-in-use” reveals that different actors (doctors and patients) adopt two different perspectives when investigating the chronic condition. Clinicians are interested in a chronological representation of patient data while patients and families are interested in making sense of specific situations, adopting a kairotic perspective (Kairos: the right moment) that emphasises the instant in which something significant for someone happens.

The analysis of the knowledge artefacts-in-use has a twofold outcome. On one hand, it illustrates the mutual shaping of knowing, artefacts and practices. On the other hand, it shows how knowledge artefact can become pivotal resources in a fragmented system of knowledge.

Personal Health Record (PHR) systems make possible to integrate data from different sources and circulate them within the illness care and management network. The new arrangements prefigure a redefinition of the relations among healthcare practitioners, patients, and caregivers. The purpose of this paper is to consider the role and the meanings attributed to information when a technical artifact enables new forms of communication within the healthcare management network.

The authors adopted a qualitative research design, conducting a pre-post analysis on a theoretical sample of patients and of a paediatrics department. The authors selected 12 patients (six females and six males) aged between four and 20 years old.

The patients were willing to act as “stewards of their own information” (Halamka et al., 2008), but they interpreted this role in terms of restricting access to their information, rather than facilitating its dissemination. In fact, the PHR was symbolized as an instrument to support personal diabetes management but the patients want to preserve their own competence and independent management on the information regarding their “Personal” diseases.

This work highlights two connotation of “Personal” information. The first is the dimension of the right to the privacy of information when it is believed that it may be used to pass judgement on the patient. The second connotation of “Personal” is the assertion by patients of their competence and autonomy in interpreting the information on the basis of personal knowledge about their diabetes.
