Global climate agreements call for action and an integrated perspective on mobility, energy and overall consumption. Municipalities in dense, urban areas are challenged with facilitating this transition with limited space and energy resources, and with future uncertainties. One important aspect of the transition is the adoption of electric vehicles, which includes the adequate design of charging infrastructure. Another important goal is a modal shift in transportation. This study investigated over 80 urban mobility policy measures that are in the policy roadmap of two of the largest municipalities of the Netherlands. This analysis consists of an inventory of policy measures, an evaluation of their environmental effects and conceptualizations of the policy objectives and conditions within the mobility transitions. The findings reveal that the two municipalities have similarities in means, there is still little anticipation of future technology and policy conditions could be further satisfied by introducing tailored measures for specific user groups.
Young widowhood, conceptualized as the loss of one’s spouse before the age of 50, is a profoundly painful and distressing loss (Den Elzen, 2017, 2018). The literature on young widowhood shows the death of a partner generally causes a fragmentation of the self, as it violates expectations of the normal life cycle, namely growing old together (Haase and Johnston, 2012; Levinson, 1997). Premature loss of one’s spouse tends to be experienced by the surviving partner as distressing or traumatizing, such as having witnessed their suffering in illness or through accident (Den Elzen, 2018) or in struggling with unfinished business (Holland et al, 2020). Whilst post-traumatic stress is well-known and has been widely researched across various disciplines, the concept of post-traumatic growth is much newer and by contrast has received less attention. PTG was introduced as a scholarly concept by Tedeschi and Calhoun in the mid-1990s and is defined as a positive psychological change as a result of the struggle with highly challenging life events (2004). Calhoun and Tedeschi’s notion of PTG has been backed by a recent systematic review. In the first meta-analysis of moderate-to-high PTG, Wu et al. found that of the 10,181 subjects, about 50% experienced PTG (2019). They also reported that women, young people and victims of trauma experienced higher levels of PTG than men, the elderly and those who experienced indirect trauma. PTG has attracted some controversy, with some researchers questioning its scientific validity (Jayawickreme and Blackie, 2014). Others caution against the minimization of people’s suffering. Hayward is a trauma counsellor who advises approaching PTG carefully, highlighting that if it is introduced with clients too early it can "often be construed as minimizing someone's pain and suffering and minimizing the impact of the loss" (cited in Collier, 2016, n.p.). In addressing the critique of PTG, Calhoun and Tedeschi (2006) emphasize that the focus on investigating positive psychological change following trauma does not deny the common and well-documented negative psychological responses and distress following severe life stresses: “Negative events tend to produce, for most persons, consequences that are negative” (p.4). They argue however, and their research supports this finding, that for many people distressful events can foster positive psychological changes. We view PTG as a possibility following (profound) loss, and emphasize that PTG may continue to co-exist with painful and/or unresolved emotions regarding the loss itself. We conceptualize PTG as a continuum and not as an either/or binary with grief. Further, we wish to highlight that PTG is a highly individual process that depends on many factors, and we are not suggesting that the absence of PTG is to be seen as a failure. This chapter intends to contribute to the study of PTG through a person-centered approach. The most used method to assess PTG is the 21-item posttraumatic growth inventory developed by Calhoun and Tedeschi in 1996 (Jayawickreme & Blackie, 2014). Self-reported posttraumatic growth has been the foundation of PTG research, which has aimed to identify to what extent PTG evokes improved psychological and physical health. In discussing our own creative narrative processes of PTG, our practice-led-research lens aims to contribute to research on how PTG might be fostered. We propose a Writing-for-wellbeing approach in this context and explore what it offered us both as writers and widows and what it might offer the field of Writing-for-wellbeing and by extension clinical and scholarly practice.
Research finds that the global market value of cargo bikes will hit 2.4 billion euros by 2031. Analysts with Future Market Insights assessing the growth of cargo bikes have placed the parcel courier industry as a key buyer of electric cargo bikes, forecasting that 43 per cent of sales could go to this industry. This growth is driven by city logistics trends, particularly as studies emerge showing the high efficiency and cost saving of the cargo bike versus the delivery van. It will not solely be direct incentives that drive uptake, however. The policy that restricts motoring and emissions is expected to be a key driver for businesses that seek profitability, with three-wheeled electric cargo bikes making up nearly half the market. The advance of e-bike technology has seen a strong rise in market share for assisted cargo bikes, now accounting for a 73 per cent market share. Potentially limiting the growth is the legislation governing the output and range of electric cargo bikes (FMI, 2021).To deal with the issues of faster delivery, clean delivery (low/zero emission) and less space in dense cities, the light electric freight vehicle (LEFV) can be–and is used more and more as–an innovative solution. The way logistics in urban areas is organized is being challenged, as the global growth of cities leads to more jobs, more businesses and more residents. As a result, companies, workers, residents and visitors demand more goods and produce more waste. More space for logistics activities in and around cities is at odds with the growing need for accommodation for people living and working in cities.

Chemical preservation is an important process that prevents foods, personal care products, woods and household products, such as paints and coatings, from undesirable change or decomposition by microbial growth. To date, many different chemical preservatives are commercially available, but they are also associated with health threats and severe negative environmental impact. The demand for novel, safe, and green chemical preservatives is growing, and this process is further accelerated by the European Green Deal. It is expected that by the year of 2050 (or even as soon as 2035), all preservatives that do not meet the ‘safe-by-design’ and ‘biodegradability’ criteria are banned from production and use. To meet these European goals, there is a large need for the development of green, circular, and bio-degradable antimicrobial compounds that can serve as alternatives for the currently available biocidals/ preservatives. Anthocyanins, derived from fruits and flowers, meet these sustainability goals. Furthermore, preliminary research at the Hanze University of Applied Science has confirmed the antimicrobial efficacy of rose and tulip anthocyanin extracts against an array of microbial species. Therefore, these molecules have the potential to serve as novel, sustainable chemical preservatives. In the current project we develop a strategy consisting of fractionation and state-of-the-art characterization methods of individual anthocyanins and subsequent in vitro screening to identify anthocyanin-molecules with potent antimicrobial efficacy for application in paints, coatings and other products. To our knowledge this is the first attempt that combines in-depth chemical characterization of individual anthocyanins in relation to their antimicrobial efficacy. Once developed, this strategy will allow us to single out anthocyanin molecules with antimicrobial properties and give us insight in structure-activity relations of individual anthocyanins. Our approach is the first step towards the development of anthocyanin molecules as novel, circular and biodegradable non-toxic plant-based preservatives.
Worldwide, coral reefs are rapidly declining due to increased sea water temperatures and other environmental stresses (Figure 1). To counter the extinction of major coral reef building species on the island of Bonaire, the non-profit organization Reef Renewal Foundation Bonaire is restoring degraded reef sites using corals that are grown in local nurseries. In these nurseries, corals are propagated on artificial trees using fragmentation. After 6-8 months of growth in the nursery, the corals are transplanted to degraded reef sites around the island. Over the years more than 21.000 corals have been outplanted to reef restoration sites in this way. These corals show high survivorship under natural reef conditions but remain under threat by environmental disturbances, such as increased water temperatures, diseases, and competition with macroalgae. A promising intervention to increase reef persistence and resilience is to manipulate the coral-associated microbiome. At present, the composition of the microbiome in nursery-reared and outplanted corals on Bonaire is unknown. The aim of the current project is to identify and isolate naturally occurring beneficial bacteria that may stimulate the resilience of these corals. Our key objectives are: 1) to assess the presence of functionally beneficial bacteria in corals in nursery and restoration sites on Bonaire using metagenomic screening. 2) to design culture strategies to isolate these functionally beneficial bacteria. In the future, a selection of these beneficial bacteria can be applied to the corals to increase their resilience against environmental disturbances.
The seaweed aquaculture sector, aimed at cultivation of macroalgal biomass to be converted into commercial applications, can be placed within a sustainable and circular economy framework. This bio-based sector has the potential to aid the European Union meet multiple EU Bioeconomy Strategy, EU Green Deal and Blue Growth Strategy objectives. Seaweeds play a crucial ecological role within the marine environment and provide several ecosystem services, from the take up of excess nutrients from surrounding seawater to oxygen production and potentially carbon sequestration. Sea lettuce, Ulva spp., is a green seaweed, growing wild in the Atlantic Ocean and North Sea. Sea lettuce has a high nutritional value and is a promising source for food, animal feed, cosmetics and more. Sea lettuce, when produced in controlled conditions like aquaculture, can supplement our diet with healthy and safe proteins, fibres and vitamins. However, at this moment, Sea lettuce is hardly exploited as resource because of its unfamiliarity but also lack of knowledge about its growth cycle, its interaction with microbiota and eventually, possible applications. Even, it is unknown which Ulva species are available for aquaculture (algaculture) and how these species can contribute to a sustainable aquaculture biomass production. The AQULVA project aims to investigate which Ulva species are available in the North Sea and Wadden Sea which can be utilised in onshore aquaculture production. Modern genomic, microbiomic and metabolomic profiling techniques alongside ecophysiological production research must reveal suitable Ulva selections with high nutritional value for sustainable onshore biomass production. Selected Ulva spp lines will be used for production of healthy and safe foods, anti-aging cosmetics and added value animal feed supplements for dairy farming. This applied research is in cooperation with a network of SME’s, Research Institutes and Universities of Applied Science and is liaised with EU initiatives like the EU-COST action “SeaWheat”.
