In de afgelopen jaren groeide het besef dat veel inwoners die een beroep doen op de publieke dienstverlening de nodige stress en zorgen ervaren. Werkloosheid, hoge schulden of problemen in de opvoeding kunnen eraan bijdragen dat het leven van mensen meer vraagt dan zij aankunnen. Het besef dat chronische stress een wissel trekt op het functioneren heeft een groeiende groep publieke dienstverleners geïnspireerd om in de ondersteuning die zij inwoners bieden, (meer) rekening te houden met de doorwerking van de stress op gedrag. Dat een aanhoudend stroom van zorgen verklaart waarom inwoners die hulp nodig hebben te vaak niet in staat blijken om de processtappen te zetten die van hen worden gevraagd: stukken aanleveren, geen afspraken missen, solliciteren, rondkomen van weekgeld, et cetera. Een van de belangrijkste middelen voor professionals om inwoners te motiveren en te ondersteunen de processtappen toch te zetten is het gesprek. Veel professionals (en hun management) hebben de neiging om vooral aandacht te besteden aan de inhoud van die gesprekken. Een verkenning van studies naar de impact van inrichting op ervaren stress leert dat ook de inrichting van een gebouw kan bijdragen aan stress-sensitieve dienstverlening. Op verzoek van de gemeente Utrecht en in nauwe samenwerking met Studio Sociaal Centraal heeft het lectoraat Schulden en Incasso een literatuurverkenning uitgevoerd om de gemeente Utrecht en andere uitvoerders van publieke dienstverlening op weg te helpen bij het inrichten van ontmoetingsruimten voor professionals die uitvoering geven aan onder meer de schuldhulpverlening, re-integratie, Wmo, jeugdhulpverlening en jeugdgezondheidszorg.
Purpose – In many organizations, a major part of the daily activities is perceived as concentrated work (53% in this study). Hence, a lack of privacy at the workplace may be considered as a serious environmental stressor. Activity-based work environments usually provide non-assigned private rooms, to be used on an as-need basis. Is this an effective stress management solution?Design/Methodology – Repeated measurements were collected, using a mobile application. Respondents provided data about their activities, the workplaces they used, and the degree of job strain they experienced. They also filled out a questionnaire regarding psychological and job characteristics.Results – A total of 3480 measurements was provided by 114 respondents, working at a Dutch public service organisation. The availability of private rooms did not seem to provide an effective stress management solution. Only 17% of the concentrated work was indeed performed in these rooms. When other types of workplaces were used, this caused (strong) dissatisfaction in 40% of the occasions. This dissatisfaction correlated with individual differences regarding need for privacy (p = .026).Limitations – Because only one specific organization and work environment is studied, further research is needed to test the generalizability of our findings.Research/Practical Implications – When performing concentrated work, people often choose not to use a private room, despite their dissatisfaction. Further research should focus on explaining and possibly influencing this behaviour.Originality/Value – Repeatedly measuring activity type together with workplace type and workplace satisfaction, provides a solid basis to analyse behavioural patterns and environmental stressors within activity-based work environments.
The demanding environment that contemporary dance students are exposed to could result in high stress levels, which can influence injury susceptibility. Therefore, this study aims to investigate the association between stress and injuries. In the period between September 2016 and March 2020, four cohorts of first-year dance students (N = 186; mean age 19.21 ± 1.35 years) were followed for one academic year. Each month, general stress was assessed on a 0-100 visual analogous scale. The Oslo Sports Trauma Research Center Questionnaire on Health Problems was used on a monthly basis to monitor injuries. Injuries were defined as "all injuries" (i.e., any physical complaint irrespective of the need for medical attention or time-loss from dance) and "substantial injuries" (i.e., leading to moderate/severe/complete reductions in training volume or performance). Mann-Whitney tests were performed to measure differences in general stress levels between injured and injury-free students, while repeated-measures ANOVA were performed to investigate whether general stress scores increased before and during injury occurrence. The overall average monthly general stress score over all cohorts for all students was 39.81. The monthly general stress scores ranged from 31.75 to 49.16. Overall, injured and substantially injured students reported higher stress scores than injury-free students, with significant differences in 3 out of the 9 months for all injuries (September, October, March, p < 0.05), and in 5 months for substantial injuries (September, October, November, December, April, p < 0.05). Within the 3-month period before and during injury occurrence, a (marginally) significant linear effect of general stress across the time periods was found for all injuries [F(1.87,216.49) = 3.10, p = 0.051] and substantial injuries [F(2,138) = 4.16, p = 0.018]. The results indicate an association between general stress and injuries. Future research should focus on effects of varying stress levels on injury risk using higher sampling frequency, for instance by measuring weekly since stress levels are likely to fluctuate daily. Practically, strategies aiming at stress reduction might have the potential to reduce the burden of dance injuries and may have positive outcomes for dancers, teachers, schools, and companies.
Currently, many novel innovative materials and manufacturing methods are developed in order to help businesses for improving their performance, developing new products, and also implement more sustainability into their current processes. For this purpose, additive manufacturing (AM) technology has been very successful in the fabrication of complex shape products, that cannot be manufactured by conventional approaches, and also using novel high-performance materials with more sustainable aspects. The application of bioplastics and biopolymers is growing fast in the 3D printing industry. Since they are good alternatives to petrochemical products that have negative impacts on environments, therefore, many research studies have been exploring and developing new biopolymers and 3D printing techniques for the fabrication of fully biobased products. In particular, 3D printing of smart biopolymers has attracted much attention due to the specific functionalities of the fabricated products. They have a unique ability to recover their original shape from a significant plastic deformation when a particular stimulus, like temperature, is applied. Therefore, the application of smart biopolymers in the 3D printing process gives an additional dimension (time) to this technology, called four-dimensional (4D) printing, and it highlights the promise for further development of 4D printing in the design and fabrication of smart structures and products. This performance in combination with specific complex designs, such as sandwich structures, allows the production of for example impact-resistant, stress-absorber panels, lightweight products for sporting goods, automotive, or many other applications. In this study, an experimental approach will be applied to fabricate a suitable biopolymer with a shape memory behavior and also investigate the impact of design and operational parameters on the functionality of 4D printed sandwich structures, especially, stress absorption rate and shape recovery behavior.
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.
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%.
