Although reengineering is strategically advantageous fororganisations in order to keep functional and sustainable, safety must remain apriority and respective efforts need to be maintained. This paper suggeststhe combination of soft system methodology (SSM) and Pareto analysison the scope of safety management performance evaluation, and presents theresults of a survey, which was conducted in order to assess the effectiveness,efficacy and ethicality of the individual components of an organisation’s safetyprogram. The research employed quantitative and qualitative data and ensureda broad representation of functional managers and safety professionals, whocollectively hold the responsibility for planning, implementing and monitoringsafety practices. The results showed that SSM can support the assessment ofsafety management performance by revealing weaknesses of safety initiatives,and Pareto analysis can underwrite the prioritisation of the remedies required.The specific methodology might be adapted by any organisation that requires adeep evaluation of its safety management performance, seeks to uncover themechanisms that affect such performance, and, under limited resources, needsto focus on the most influential deficiencies.

Renewable energy sources have an intermittent character that does not necessarily match energy demand. Such imbalances tend to increase system cost as they require mitigation measures and this is undesirable when available resources should be focused on increasing renewable energy supply. Matching supply and demand should therefore be inherent to early stages of system design, to avoid mismatch costs to the greatest extent possible and we need guidelines for that. This paper delivers such guidelines by exploring design of hybrid wind and solar energy and unusual large solar installation angles. The hybrid wind and solar energy supply and energy demand is studied with an analytical analysis of average monthly energy yields in The Netherlands, Spain and Britain, capacity factor statistics and a dynamic energy supply simulation. The analytical focus in this paper differs from that found in literature, where analyses entirely rely on simulations. Additionally, the seasonal energy yield profile of solar energy at large installation angles is studied with the web application PVGIS and an hourly simulation of the energy yield, based on the Perez model. In Europe, the energy yield of solar PV peaks during the summer months and the energy yield of wind turbines is highest during the winter months. As a consequence, three basic hybrid supply profiles, based on three different mix ratios of wind to solar PV, can be differentiated: a heating profile with high monthly energy yield during the winter months, a flat or baseload profile and a cooling profile with high monthly energy yield during the summer months. It is shown that the baseload profile in The Netherlands is achieved at a ratio of wind to solar energy yield and power of respectively Ew/Es = 1.7 and Pw/Ps = 0.6. The baseload ratio for Spain and Britain is comparable because of similar seasonal weather patterns, so that this baseload ratio is likely comparable for other European countries too. In addition to the seasonal benefits, the hybrid mix is also ideal for the short-term as wind and solar PV adds up to a total that has fewer energy supply flaws and peaks than with each energy source individually and it is shown that they are seldom (3%) both at rated power. This allows them to share one cable, allowing “cable pooling”, with curtailment to -for example-manage cable capacity. A dynamic simulation with the baseload mix supply and a flat demand reveals that a 100% and 75% yearly energy match cause a curtailment loss of respectively 6% and 1%. Curtailment losses of the baseload mix are thereby shown to be small. Tuning of the energy supply of solar panels separately is also possible. Compared to standard 40◦ slope in The Netherlands, facade panels have smaller yield during the summer months, but almost equal yield during the rest of the year, so that the total yield adds up to 72% of standard 40◦ slope panels. Additionally, an hourly energy yield simulation reveals that: façade (90◦) and 60◦ slope panels with an inverter rated at respectively 50% and 65% Wp, produce 95% of the maximum energy yield at that slope. The flatter seasonal yield profile of “large slope panels” together with decreased peak power fits Dutch demand and grid capacity more effectively.

Within paediatric palliative care, it is essential for families and providers to have open, equal, and trusting relationships. In practice, however, building relationships can be challenging. Investing in better understanding the differences in each other's frames of reference and underlying values seems important. Wonder Lab practices provide a space to explore these differences by focusing together on life phenomena in curious and Socratic ways. Wonder Labs were organised with parents, healthcare professionals, and students involved in Dutch paediatric palliative care. The aim of this study was to develop an understanding of how participants experienced participating in Wonder Labs. We conducted twenty in-depth interviews with Wonder Lab participants and used inductive thematic analysis for data interpretation. Five themes were identified: Slowing down, Appreciating stories, Becoming vulnerable, Opening up and diving in, and Reframing perspectives. Participating in Wonder Labs allowed mothers, healthcare professionals, and students to contribute to deepening experiences and gain an expanded understanding of what is at play in caring for children with life-limiting and life-threatening conditions. Through working in pluralised groups, frames of reference and understandings complemented each other and could change. Participants often adopted a more open attitude towards others involved in care after participating and adapted day-to-day practices. Deliberating within paediatric palliative care on sensitive issues and their underlying personal and professional beliefs and values must be part of working together, without specific care situations being the catalyst. This may foster the mutual understanding needed in searching for quality of life, death, and bereavement.

In the Netherlands, many parents of children with profound intellectual and multiple disabilities care for their children at home. Little is known about how parents and involved healthcare professionals share and align medical care for these children. This study aims to contribute to a better understanding of the dimensions that affect how medical care is shared and how healthcare professionals can align care with family needs. The study design was inspired by grounded theory. We analyzed in-depth interviews with 25 Dutch parents. The analysis identified five dimensions affecting how parents and professionals shared and aligned medical care: fragility, planned care, irregularities, interactions with providers, and parents’ choices. We recognized three distinctive ways these dimensions interplayed, characterizing scenarios of sharing care: dependent care, dialogical care, and autonomous care. The findings illuminated that parental distress decreased when parents could communicate about what they considered important for their child and family and its implications for sharing care. Parents developed their capacity to manage medical care and often evolved in their thinking about the quality of care and life. Sometimes this evolution was due to struggles with the care provided by professionals. Therefore, healthcare professionals may need to broaden the relational work of shared decision-making to include the sharing of medical care. Arrangements need to be continually reassessed as changes in the child’s and family’s situation trigger changes in preferred patterns of sharing care. Commitment to parents’ autonomy implies that healthcare professionals should be attentive to the parents’ emotional and relational needs.

Background Parenting a child with profound intellectual and multiple disabilities has great implications. Parents generally rely heavily on healthcare and social welfare services in caring for the child at home. Previous studies indicated mismatch between what parents need to preserve family and personal wellbeing and what is typically provided by services. This study focused on the role of healthcare and social welfare services in childcare and aims to contribute to understanding how parents perceive their interactions with service providers. Methods We interviewed 25 Dutch parents who cared for their child at home. Data were analysed using Framework Method. Findings Two overarching themes were found: “Being the lifeline” addressed that parents had central roles in fragmented services, and “Losing ownership” highlighted that parents were constrained in living life according to own beliefs and values while interacting with providers. Conclusions Findings illuminated that many parents became overburdened and compromised heavily on agency over family thriving due to functioning of healthcare and social welfare services. Findings supported working with integrated family case managers, creating effective and proactive access to equipment and services, and enacting high quality facilities for help with childcare and respite. These are important conditions to enable parents to construct family life more autonomously and make their further contribution to society. This may also lead to improved connotations of dependence on healthcare and social welfare services.

Most multi‑problem young adults (18–27 years old) have been exposed to childhood maltreatment and/or have been involved in juvenile delinquency and, therefore, could have had Child Protection Service (CPS) interference during childhood. The extent to which their childhood problems persist and evolve into young adult‑ hood may differ substantially among cases. This might indicate heterogeneous profiles of CPS risk factors. These pro‑ files may identify combinations of closely interrelated childhood problems which may warrant specific approaches for problem recognition and intervention in clinical practice. The aim of this study was to retrospectively identify distinct statistical classes based on CPS data of multi‑problem young adults in The Netherlands and to explore whether these classes were related to current psychological dysfunctioning and delinquent behaviour.

Developing a reliable method to compare food sustainability is gaining traction, with efforts like those by the Food and Agriculture Organization (FAO). This research aims to contribute to a comprehensive scientific comparison of food categories based on CO2 emissions linked not to weight but to their primary function: nutrient availability and uptake in the consumer’s body. The study utilizes a multi-criteria evaluation for sustainability, incorporating the Nutrient Rich Food (NRF) score, protein digestibility, and essential amino acid content. A case study compares one serving of semi-skimmed milk (SSM) with various plant-based beverages (oat, soy, rice, coconut, and almond), considering their carbon footprints in relation to nutrient content and environmental costs. The analysis integrates protein quality through essential amino acid proportion and digestibility. Findings reveal that achieving an NRF11.3 score of 50 requires more servings of unfortified plant-based beverages than semi-skimmed milk, resulting in higher carbon footprints, except for soy drink. However, when considering emerging farm management measures, semi-skimmed and soy drinks show comparable carbon footprints for a given NRF score. Fortified plant-based beverages (soy, oat, and almond) exhibit lower footprints relative to the calculated NRF scores. Yet, when converting carbon footprints to euros using the European Union Emissions Trading System and adding them to retail prices per kilogram, semi-skimmed milk emerges as the option with the lowest “societal costs” (environment and consumer costs). The research underscores that understanding a food product’s nutritional value requires more than knowledge of its composition; uptake into the body maintenance and potential synergistic effects of other components in the food matrix play crucial roles.

As an active member of the Global Network for Age-Friendly Cities and Communities, The Hague has been monitoring the progress over the years. In 2022, a second cross-sectional survey based on the Age Friendly Cities and Communities Questionnaire (AFCCQ) was conducted among 396 community-dwelling older citizens in the municipality. During times of the pandemic, scores for Social Participation went notably down, and scores for Respect and Social Inclusion increased. For the first time, based on survey data, four personas were found through cluster analysis. These personas ranged from the precariat and people with personal health issues with lower scores, to the silent majority without the limitations of health problems, and the upper echelon who score positively in all domains. Age-friendly policies in The Hague should focus particularly on the first two clusters through dedicated action plans, which would help steer efforts towards those most in need for support. This would help The Hague to become an age-friendly city for all, and not only for those living in good health and with sufficient financial means.

The world is rapidly transforming. Economic, ecological and technological developments transcend existing boundaries and challenge the way we innovate. The challenge we face is to reinvent innovation as well, changing the way organisations and industries innovate and cooperate. Only with a new approach we can design a better future: an approach where stakeholders from government, organisations, companies and users participate in new ways of collaboration; an approach where solutions are realised that makes our society future-proof. Participatory innovation means that the innovation team changes: expanding beyond the boundaries of the own organisation. For organisations and companies, this is a huge step. Every partner must be willing to think and act beyond their own borders and participate in a joint effort. Participative innovation is a new way of working, where new challenges are encountered. In the field of urban lighting, this transformation is strongly felt. This paper will further explore the challenge and describe a rich case study where participative innovation is used to rethink, redesign and realise the solutions to transform urban lighting from functional lighting to improving social quality.
