Purpose This study aims to enhance understanding of the collaboration between chairs of nurse councils (CNCs) and members of executive hospital boards (BM) from a relational leadership perspective. Design/methodology/approach The authors used a qualitative and interpretive methodology. The authors study the daily interactions of BM and CNCs of seven Dutch hospitals through a relational leadership lens. The authors used a combination of observations, interviews and document analysis. The author’s qualitative analysis was used to grasp the process of collaborating between BM and CNCs. Findings Knowing each other, relating with and relating to are distinct but intertwined processes that influence the collaboration between BM and CNC. The absence of conflict is also regarded as a finding in this paper. Combined together, they show the importance of a relational process perspective to understand the complexity of collaboration in hospitals. Originality/value Collaboration between professional groups in hospitals is becoming more important due to increasing interdependence. This is a consequence of the complexity in organizing qualitative care. Nevertheless, research on the process of collaborating between nurse councils (NCs) and executive hospital boards is scarce. Furthermore, the understanding of the workings of boards, in general, is limited. The relational process perspective and the combination of observations, interviewing and document analysis proved valuable in this study and is underrepresented in leadership research. This process perspective is a valuable addition to skills- and competencies-focused leadership literature.

OBJECTIVE: The aim of this study was to explore the longitudinal relationship between sitting time on a working day and vitality, work performance, presenteeism, and sickness absence.METHODS: At the start and end of a five-month intervention program at the workplace, as well as 10 months after the intervention, sitting time and work-related outcomes were measured using a standardized self-administered questionnaire and company records. Generalized linear mixed models were used to estimate the longitudinal relationship between sitting time and work-related outcomes, and possible interaction effects over time.RESULTS: A significant and sustainable decrease in sitting time on a working day was observed. Sitting less was significantly related to higher vitality scores, but this effect was marginal (b = -0.0006, P = 0.000).CONCLUSIONS: Our finding of significant though marginal associations between sitting time and important work-related outcomes justifies further research.
The growing energy demand and environmental impact of traditional sources highlight the need for sustainable solutions. Hydrogen produced through water electrolysis, is a flexible and clean energy carrier capable of addressing large-electricity storage needs of the renewable but intermittent energy sources. Among various technologies, Proton Exchange Membrane Water Electrolysis (PEMWE) stands out for its efficiency and rapid response, making it ideal for grid stabilization. In its core, PEMWEs are composed of membrane electrode assemblies (MEA), which consist of a proton-conducting membrane sandwiched between two catalyst-coated electrodes, forming a single PEMWE cell unit. Despite the high efficiency and low emissions, a principal drawback of PEMWE is the capital cost due to high loading of precious metal catalysts and protective coatings. Traditional MEA catalyst coating methods are complex, inefficient, and costly to scale. To circumvent these challenges, VSParticle developed a technology for nanoparticle film production using spark ablation, which generates nanoparticles through high-voltage discharges between electrodes followed by an impaction printing module. However, the absence of liquids poses challenges, such as integrating polymeric solutions (e.g., Nafion®) for uniform, thicker catalyst coatings. Electrohydrodynamic atomization (EHDA) stands out as a promising technique thanks to its strong electric fields used to generate micro- and nanometric droplets with a narrow size distribution. Co-axial EHDA, a variation of this technique, utilizes two concentric needles to spray different fluids simultaneously.The ESPRESSO-NANO project combines co-axial EHDA with spark ablation to improve catalyst uniformity and performance at the nanometer scale by integrating electrosprayed ionomer nanoparticles with dry metal nanoparticles, ensuring better distribution of the catalyst within the nanoporous layer. This novel approach streamlines numerous steps in traditional synthesis and electrocatalyst film production which will address material waste and energy consumption, while simultaneously improve the electrochemical efficiency of PEMWEs, offering a sustainable solution to the global energy crisis.
The main aim of KiNESIS is to create a Knowledge Alliance among academia, NGOs, communities, local authorities, businesses to develop a program of multidisciplinary activities in shrinking areas with the aim of promoting and fostering ideas, projects, workforce, productivity and attractiveness. The problems affecting peripheral territories in rural or mountain areas of the interior regions, compared to small, medium or large population centres and large European capitals, are related to complex but clear phenomena: the emigration of young generations, abandonment and loneliness of elderly people, the loss of jobs, the deterioration of buildings and land, the closing of schools and related services, the disappearance of traditions and customs, the contraction of local governments, which in absence of adequate solutions can only generate worse conditions, leading to the abandonment of areas rich in history, culture and traditions. It is important that these communities - spread all over Europe - are not abandoned since they are rich in cultural traditions, which need to be preserved with a view to new developments, intended as "intelligent" rebirth and recovery.The focus of KiNESIS is to converge the interest of different stakeholders by recalling various skills around abandoned villages to make them "smart" and "attractive".Keeping in mind the triangular objectives of cooperation and innovation of research, higher education and business of the Knowledge Alliance action, the project aims are: i) revitalising depopulated areas by stimulating entrepreneurship and entrepreneurial skills; ii) creating local living laboratories, shared at European level, in which the exchange of knowledge, best practices, experiences can help promote social inclusion and entrepreneurial development;iii) experimenting new, innovative and multidisciplinary approaches in teaching and learning; iv) facilitating the exchange, flow and co-creation of knowledge at a local and global level.
Environmental nano- and micro-plastics (NMPs) are highly diverse [2]. Accounting for this diversity is one of the main challenges to develop a comprehensive understanding of NMPs detection, quantification, fate, and risks [3]. Two major issues currently limit progresses within this field: (a) validation and broadening the current analytical tools (b) uncertainty with respect to NMPs occurrence and behaviour at small scales (< 20 micron). Tracking NMPs in environmental systems is currently limited to micron size plastics due to the size detection limit of the available analytical techniques. There are currently many uncertainties regarding detecting nanoplastics in real environmental systems, e.g. the inexistence of commercially available NMPs and incompatibility between them and those generated from plastic fragments degradation in the environment. Trying to tackle these problems some research groups synthesized NMPs dopped with metals inside [16]. However, even though elemental analysis techniques (ICP-MS) are rather sensitive, the low volume of these metals encapsulated in the nanoparticles make their detection rather challenging. At the same time, due to Sars-Cov-19 pandemic, nucleic acid identification technologies (LAMP, PCR) experienced a fast evolution and are able to provide detection at very low levels with very compact and reliable equipment. Nuclepar proposes the use of Electrohydrodynamic Atomization (EHDA) to generate NMPs coated with nucleic acids of different polymer types, sizes, and shapes, which can be used as support for detection of such particles using PCR-LAMP technology. If proven possible, Nuclepar might become a first step towards an easy NMPs detection tool. This knowledge will certainly impact current risk assessment tools, efficient interventions to limit emissions and adequate regulations related to NMPs.
