This review evaluates the methodological quality of current front-of-pack labeling research and discusses future research challenges. Peer-reviewed articles were identified using a computerized search of the databases PubMed andWeb of Science (ISI) from1990 to February 2011; reference lists fromkey published articleswere used as well. The quality of the 31 included studies was assessed. The results showed that the methodological quality of published front-of-pack labeling research is generally low to mediocre; objective observational data-based consumer studies were of higher quality than consumer studies relying on self-reports. Experimental studies that included a control group were lacking. The review further revealed a lack of a validated methodology to measure the use of front-of-pack labels and the effects of these labels in real-life settings. In conclusion, few methodologically sound front-of-pack labeling studies are presently available. The highest methodological quality and the greatest public health relevance are achieved by measuring the health effects of front-of-pack labels using biomarkers in a longitudinal, randomized, controlled design in a real-life setting.

Utrecht, The Netherlands. abstract Audit trail procedures are applied as a way to check the validity of qualitative research designs, qualitative analyses, and the claims that are made. Audit trail procedures can be conducted based on the three criteria of visibility, comprehensibility, and acceptability (Akkerman et al., 2008). During an audit trail procedure, all documents and materials resulting from the data gathering and the data analysis are assessed by an auditor. In this presentation, we presented a summative audit trail procedure (Agricola, Prins, Van der Schaaf & Van Tartwijk, 2021), whereas in a second study we used a formative one (Agricola, Van der Schaaf, Prins & Van Tartwijk, 2022). For both studies, two different auditors were chosen. For the study presented in Agricola et al. (2021) the auditor was one of the PhD supervisors, while in that presented Agricola et al. (2022) was a junior researcher not involved in the project. The first auditor had a high level of expertise in the study’s topic and methodology. As a result, he was able to provide a professional and critical assessment report. Although the second auditor might be considered to be more objective than the first, as she was not involved in the project, more meetings were needed to explain the aim of the study and the aim of the audit trail procedure. There are many ideas about the criteria that qualitative studies should meet (De Kleijn en Van Leeuwen, 2018). I argue that procedures of checking for interrater agreement and understanding, the triangulation, and audit trail procedures can increase the internal validity of qualitative studies. Agricola, B.

BACKGROUND: The quality standards of the Dutch Society of Intensive Care require monitoring of the satisfaction of patient's relatives with respect to care. Currently, no suitable instrument is available in the Netherlands to measure this. This study describes the development and psychometric evaluation of the questionnaire-based Consumer Quality Index 'Relatives in Intensive Care Unit' (CQI 'R-ICU'). The CQI 'R-ICU' measures the perceived quality of care from the perspective of patients' relatives, and identifies aspects of care that need improvement.METHODS: The CQI 'R-ICU' was developed using a mixed method design. Items were based on quality of care aspects from earlier studies and from focus group interviews with patients' relatives. The time period for the data collection of the psychometric evaluation was from October 2011 until July 2012. Relatives of adult intensive care patients in one university hospital and five general hospitals in the Netherlands were approached to participate. Psychometric evaluation included item analysis, inter-item analysis, and factor analysis.RESULTS: Twelve aspects were noted as being indicators of quality of care, and were subsequently selected for the questionnaire's vocabulary. The response rate of patients' relatives was 81% (n = 455). Quality of care was represented by two clusters, each showing a high reliability: 'Communication' (α = .80) and 'Participation' (α = .84). Relatives ranked the following aspects for quality of care as most important: no conflicting information, information from doctors and nurses is comprehensive, and health professionals take patients' relatives seriously. The least important care aspects were: need for contact with peers, nuisance, and contact with a spiritual counsellor. Aspects that needed the most urgent improvement (highest quality improvement scores) were: information about how relatives can contribute to the care of the patient, information about the use of meal-facilities in the hospital, and involvement in decision-making on the medical treatment of the patient.CONCLUSIONS: The CQI 'R-ICU' evaluates quality of care from the perspective of relatives of intensive care patients and provides practical information for quality assurance and improvement programs. The development and psychometric evaluation of the CQI 'R-ICU' led to a draft questionnaire, sufficient to justify further research into the reliability, validity, and the discriminative power of the questionnaire.

Developing a framework that integrates Advanced Language Models into the qualitative research process.Qualitative research, vital for understanding complex phenomena, is often limited by labour-intensive data collection, transcription, and analysis processes. This hinders scalability, accessibility, and efficiency in both academic and industry contexts. As a result, insights are often delayed or incomplete, impacting decision-making, policy development, and innovation. The lack of tools to enhance accuracy and reduce human error exacerbates these challenges, particularly for projects requiring large datasets or quick iterations. Addressing these inefficiencies through AI-driven solutions like AIDA can empower researchers, enhance outcomes, and make qualitative research more inclusive, impactful, and efficient.The AIDA project enhances qualitative research by integrating AI technologies to streamline transcription, coding, and analysis processes. This innovation enables researchers to analyse larger datasets with greater efficiency and accuracy, providing faster and more comprehensive insights. By reducing manual effort and human error, AIDA empowers organisations to make informed decisions and implement evidence-based policies more effectively. Its scalability supports diverse societal and industry applications, from healthcare to market research, fostering innovation and addressing complex challenges. Ultimately, AIDA contributes to improving research quality, accessibility, and societal relevance, driving advancements across multiple sectors.
Goal: In 2030 the availability of high quality and fit-for-purpose recycled plastics has been significantly increased by implementation of InReP’s main result: Development of technologies in sorting, mechanical and chemical recycling that make high quality recycled plastics available for the two dominating polymer types; polyolefins (PE/PP) and PET. Results: Our integrated approach in the recycling of plastics will result in systemic (R1) and technological solutions for sorting & washing of plastic waste (R2), mechanical (R3) and chemical recycling (R4, R6) and upcycling (R5, R7) of polyolefins (PE & PP) and polyesters (PET). The obtained knowledge on the production of high quality recycled plastics can easily be transferred to the recycling of other plastic waste streams. Furthermore, our project aims to progress several processes (optimized sorting and washing, mechanical recycling of PP/PE, glycolysis of PET, naphtha from PP/PE and preparation of valuable monomers from PP/PET) to prototype and/or improved performance at existing pilot facilities. Our initiative will boost the attractiveness of recycling, contribute to the circular transition (technical, social, economic), increase the competitiveness of companies involved within the consortium and encourage academic research and education within this field.
Due to the existing pressure for a more rational use of the water, many public managers and industries have to re-think/adapt their processes towards a more circular approach. Such pressure is even more critical in the Rio Doce region, Minas Gerais, due to the large environmental accident occurred in 2015. Cenibra (pulp mill) is an example of such industries due to the fact that it is situated in the river basin and that it has a water demanding process. The current proposal is meant as an academic and engineering study to propose possible solutions to decrease the total water consumption of the mill and, thus, decrease the total stress on the Rio Doce basin. The work will be divided in three working packages, namely: (i) evaluation (modelling) of the mill process and water balance (ii) application and operation of a pilot scale wastewater treatment plant (iii) analysis of the impacts caused by the improvement of the process. The second work package will also be conducted (in parallel) with a lab scale setup in The Netherlands to allow fast adjustments and broaden evaluation of the setup/process performance. The actions will focus on reducing the mill total water consumption in 20%.
