Background: Over the last 30 years, stress and anxiety in children have risen exponentially, especially as a result of school expectations. As no studies have examined the effect of increased outdoor recess on children’s chronic stress levels, this preliminary work focused on comparing hair cortisol concentration (HCC) scores of elementary children who received varied amounts of daily recess. Methods: HCC scores were collected from 4th grade elementary children (N = 130) from three intervention schools (45 min daily recess) (N = 64; M = 35; F = 29) and three control schools (30 min daily recess) (N = 66; M = 31; F = 35). Results: A two-way ANOVA, F(1, 123) = 5.47, p = 0.021, ω² = 0.034, showed that the intervention group reflected lower HCC levels (marginal M = 5.69, 95% CI [−1.92, 13.30]) than the control group (marginal M = 18.22, 95% CI [10.83, 25.61]). Post hoc analysis revealed an estimated marginal mean difference of −12.53 (SE = 5.36, p = 0.021). Sample t-tests compared HCC levels against the pre-COVID normative value of 7.5 pg/mg. The intervention group HCC mean (M = 5.85, SD = 6.26) was significantly lower than the normative value, t(61) = −2.08, p = 0.042. The control group’s mean HCC (M = 18.22, SD = 41.39) was significantly higher than the normative value, t(64) = 2.09, p = 0.041. Conclusions: Increasing daily recess may contribute to lower chronic stress levels among 4th grade children. With obesity and mental health disorders on the rise and American students’ academic performance on the decline, these pilot results cannot be overlooked or dismissed. Full article

Background: Obesity and inactivity among children are at an all-time high and have been steadily increasing in prevalence over the last thirty years. The school environment provides the ideal setting for reaching a large number of children across diverse populations in order to reverse these trends. However, there are many inconsistent results yielded by school-based physical activity interventions due to implementation length, time for activities, and the use of structured physical activities. The LiiNK Project^® is a whole-child intervention addressing these gaps by providing children 45–60 min of recess (unstructured, outdoor play) in their schools daily, while the control children are allowed to engage in recess for 30 min daily. The purpose of this study was to compare the physical activity intensity and obesity rates of third- and fourth-grade children participating in the LiiNK intervention, which provides 60 min of recess for third graders and 45 min for fourth graders, to those in a control group allowed 30 min of daily recess. Methods: The children were 8–10 years old (M = 9.2; 52% females and 48% males). The intervention children comprised 90 third graders and 100 fourth graders, and the control children comprised 101 third graders and 92 fourth graders. Physical activity levels were monitored using accelerometers to assess sedentary, light, and moderate-to-vigorous physical activity (MVPA). Obesity rates were evaluated using bio-electrical impedance analysis (BIA), in which body fat percentage is calculated based on normative values using age and sex in the equation. Results: The third-grade intervention children engaged in 13 more MVPA minutes and took 900 more steps daily than their control counterparts, and also presented a greater proportion of overweight children transitioning to a healthy weight status from the fall to the spring semester. Conversely, the fourth-grade control children increased their activity by 500 steps and 15 more MVPA minutes daily. Despite this, the intervention children overall demonstrated a reduction in body fat percentage, while the control children demonstrated an increase in body fat percentage. Conclusions: Ultimately, 60 min of unstructured, outdoor play in schools provides children the best opportunity to engage in MVPA, which may positively impact body fat percentages, offering a potential strategy for combatting childhood obesity in school settings.

Background/Objectives: It is believed that outdoor play structures lead to more physical activity for kids during school recess. However, the intensity of this activity remains unknown. This study explored whether access to outdoor play structures during recess interferes with children’s physical activity levels. Methods: Forty-one children (8–10 years old) accessed play structures during the afternoon recess but not in the morning for one entire week. To control for temperature differences, the same number of participants from another school who did not access playground structures were invited to participate. Moderate to Vigorous Physical Activity (MVPA) was determined using heart rate reserve. Heart rate was recorded using the Fitbit Inspire 2 (San Francisco, CA, USA) for at least three full school days. Wilcoxon signed-rank and Mann–Whitney U tests analyzed within- and between-group differences. Results: The findings show no difference in MVPA when accessing or not accessing outdoor play structures, both within groups [(n = 37) median (25th–75th) 16 min (7–30) vs. 14 min (5–22)] and between groups [(n = 22) 16 min (7–26)]. The weekly MVPA for all participants (n = 59) [172 min (117–282)] was the strongest variable associated with MVPA during recess [t(df) = 5.40 (38), 95% CI 0.04–0.09, p < 0.001]. Conclusion: accessibility to outdoor play structures does not increase MVPA during recess in children aged 8 to 10. Therefore, schools may need various options for children to play during recess, allowing them to accumulate MVPA. Full article

Background: The US Center for Disease Control estimates that only 24% of American elementary-aged children participate in the recommended 60 min of daily physical activity. As activity levels decline, elementary schools should consider increasing movement opportunities. Activity-driven school days, where children can move their limbs freely, may increase memory retention performance, behavioral impulse control, as well as bone density, and muscle strength. Unstructured, outdoor play (recess) may provide an opportunity for the brain, bone, and muscle-stimulating limb movements to be utilized. To date, no research has focused on whether the modern child actively uses limb movements during recess, nor to what degree. The purpose of this study was to develop a reliable assessment tool (Movement Pattern Observation Tool, MPOT) to observe and record limb movements (unilateral, bilateral, and contralateral movements) of elementary children during recess, defined in this study as unstructured, outdoor play. Methods: Three observers used the MPOT to complete thirty-five observations at one elementary school during kindergarten through fifth-grade recess breaks. Results: Interrater reliability approached excellent, being that excellent is above 0.90. The ICC of the master observer and observer 3 value was 0.898 (95% CI 0.757–0.957), and the ICC of the master observer and observer 2 was 0.885 (95% CI 0.599–0.967), p < 0.03. Conclusion: Inter-rater reliability was achieved through a three-phase process. This reliable recess observation tool will contribute to the body of research linking recess to physical and cognitive health. Full article

Studies about recess have found that children have higher physical activity (PA) during outdoor recess compared to indoor recess, and well-constructed schoolyards play an important role in stimulating PA in children. This study aimed at investigating the affordances of schoolyards and outdoor recess PA in two urban and two rural primary schools in Estonia. Schoolyards were described with the geographical mapping method, children’s activities during outdoor recess were registered by using observations, and PA levels were measured with accelerometers. Students from grades two to six (8–13-year-olds) were included in the study. All observed schoolyards had different spaces including various ball game areas, climbing facilities, and slacklines. The natural environment dominated in the rural schools, and artificial surfaces dominated in the urban schools. Boys in the study tended to enjoy more sport-related activities, whereas girls preferred more social and less active activities. Students participating in outdoor recess spent about twice as much time (20.4%) on moderate-to-vigorous PA (MVPA) compared to indoor recess (9.5%), although boys were more active than girls (22.9% vs. 17.3%). All schoolyards afforded more MVPA during outdoor recess compared to indoor recess, whereas schoolyards with more space per child and natural environment elements generated more varied PA and higher MVPA. These findings confirm the importance of schoolyard design and quality for the variety and intensity of students’ PA during outdoor recess. Full article

The purpose of this study was to explore the different policies, practices, and procedures that are used on weather and recess in the Canadian context. Fifty school websites were examined, and ten key informants were interviewed. Policies, practices, and procedures from school websites were downloaded, and interviews were transcribed verbatim and analyzed using a qualitative content analysis. Fourteen schools had an outwardly facing policy, practice, or procedure for weather and recess. Cold temperatures were the most often cited reason for modifying recess to be indoors, with temperatures ranging from −20 to −40 for complete indoor recess. Precipitation was only found in four online documents but was mentioned as a reason to modify recess by all key informants. Additionally, key informants discussed variability in how recess policies, practices, and procedures were followed. The findings of this study illustrate inconsistencies in both formal and informal school weather and recess policies. With outdoor recess providing numerous opportunities to improve various domains of well-being, it is pertinent to understand the conditions on which it is being modified. Full article

The blue economy contributes significantly to the creation of the Atlantic Area’s identity. In addition, the search for outdoor experiences after the COVID-19 lockdown suspensions has renewed the popularity of nautical tourism in this area and in the world. Despite the negative effects of the economic crisis on tourism, evidence suggests that some tourist destinations in the Atlantic area are resilient. Thus, whereas some branches of the blue economy face considerable challenges to increasing competitiveness, others offer opportunities for economic growth and employment. In this context, investment is necessary to lay the foundations for the sustainable development of nautical tourism. However, regarding the role of investment in productivity and competitiveness in the context of crisis, there is no consensus among academics. Thus, we investigate whether the investment contributed to competitiveness in nautical tourism in the Atlantic Area in 2016–2020. We collected data from ORBIS for 29 nautical-tourism companies and performed a quantitative and qualitative narrative analysis of competitiveness indicators, enabling comparisons pre and during crisis. The results highlight the multiplicity of ways in which crisis impacts nautical-tourism firms. The research fills a gap in the literature by investigating the dynamic capabilities of nautical-tourism SMEs in periods of recession, with a special focus on restructuring and competitiveness strategies. Some recommendations are outlined to promote the efficiency of resources and stimulate the competitiveness of companies to allow the regional development of nautical tourism in the territory of the Atlantic area.

The thermal inertia properties of construction elements have gained a great deal of importance in building design over the last few years. Many investigations have shown that this is the key factor to improve energy efficiency and obtain optimal comfort conditions in buildings. However, experimental tests are expensive and time consuming and the development of new products requires shorter analysis times. In this sense, the goal of this research is to analyze the thermal behavior of a wall made up of lightweight concrete blocks covered with layers of insulating materials in steady- and transient-state conditions. For this, numerical and experimental studies were done, taking outdoor temperature and relative humidity as a function of time into account. Furthermore, multi-criteria optimization based on the design of the experimental methodology is used to minimize errors in thermal material properties and to understand the main parameters that influence the numerical simulation of thermal inertia. Numerical Finite Element Models (FEM) will take conduction, convection and radiation phenomena in the recesses of lightweight concrete blocks into account, as well as the film conditions established in the UNE-EN ISO 6946 standard. Finally, the numerical ISO-13786 standard and the experimental results are compared in terms of wall thermal transmittance, thermal flux, and temperature evolution, as well as the dynamic thermal inertia parameters, showing a good agreement in some cases, allowing builders, architects, and engineers to develop new construction elements in a short time with the new proposed methodology.

School recess provides a unique opportunity for children to be active. However, many children perceive smartphones as a key barrier for engaging in physical activity during recess. The aim was to investigate if a ban on smartphone usage during recess changed children’s physical activity. During August–October 2020, children from grades 4–7 (10–14 years) at six Danish schools were banned from using their smartphones during recess for a four-week period. Questionnaire and systematic observation (SOPLAY) data were collected from 814 children before intervention (baseline) and 828 during the last week of intervention (follow-up). The mean frequency of physical activity significantly increased from baseline to follow-up (odds ratio = 1.370), as did physical activity on a moderate level (odds ratio = 1.387). Vigorous physical activity significantly decreased (odds ratio = 0.851). The increase in physical activity was found among both schools having outdoor and indoor recess, among both boys and girls, and nearly equally among grades 4–7. This suggests that implementing a ban on smartphone usage during recess would improve the everyday conditions for health among a broad range of schoolchildren. Future studies are needed to further investigate the association between recess physical activity and smartphone usage. Full article

This pilot study used accelerometers to investigate the effectiveness of a multiple recess school intervention on physical activity patterns in younger elementary children using a post-test only with nonequivalent groups design. First and second grade students (N = 157) participating in a larger study, the LiiNK Project^® (Let’s inspire innovation ‘N Kids), wore accelerometers for the duration of the school day for two weeks to measure physical activity intensity and number of steps taken daily. Students attended either an intervention school (N = 90), participating in four 15-min unstructured, outdoor recesses and one 15-min character development lesson daily, or a control school (N = 67), participating in two 15-min unstructured, outdoor recesses daily and no character development program. The intervention students, grades 1 and 2, took more steps (p < 0.001) and time spent in moderate (p < 0.001) and vigorous (p < 0.001) physical activity (MVPA) than the control school students. Intervention students averaged approximately 900 more steps per day than the control school students. These results show young children given 60 min of recess daily continue to increase physical activity patterns over those with 30 min of recess daily. Next steps are to evaluate if children demonstrate healthier body fat levels as a result of these higher patterns of MVPA daily. Full article

Play is known as the core occupation of young children as it lays a foundation for their early development and physical, emotional and social wellbeing. Literature suggests that unstructured free play and mindfulness interventions may independently promote wellbeing among preschoolers. However, there is no clear evidence of their combination in supporting wellness in early learning environments. We conducted a quasi-experimental study with 42 children aged four to six years, attending two kindergartens in Hong Kong. The intervention included unstructured play with non-directional loose parts (play materials), conducted outdoors for one hour daily followed by a mindfulness intervention for 10 min per day indoors. The intervention lasted for five consecutive days. We examined happiness and aspects of playfulness before and after the intervention, finding a significant increase in all areas. Given greater freedom in play choice, children showed more disruptive behaviors during unstructured play than the control group engaging in recess as usual. We conclude that unstructured play in addition to mindfulness intervention is effective in promoting students’ happiness and playfulness, both of which may help maintain mental health and wellbeing amid stressors such as transition and separation. The increased disruptive behavior requires additional investigation. Full article

With a wide spectrum of data, case studies, monitoring, and experimental and numerical simulation techniques, the multidisciplinary approach of material, environmental, and computer science applied to the conservation of cultural heritage offers several opportunities for the heritage science and conservation community to map and monitor the state of the art of the knowledge referring to natural and human-induced climate change impacts on cultural heritage—mainly constituted by the built environment—in Europe and Latin America. The special issue “Preservation of Cultural Heritage and Resources Threatened by Climate Change” of Geosciences—launched to take stock of the existing but still fragmentary knowledge on this challenge, and to enable the community to respond to the implementation of the Paris agreement—includes 10 research articles. These papers exploit a broad range of data derived from preventive conservation monitoring conducted indoors in museums, churches, historical buildings, or outdoors in archeological sites and city centers. Case studies presented in the papers focus on a well-assorted sample of decay phenomena occurring on heritage materials—e.g., surface recession and biomass accumulation on limestone, depositions of pollutant on marble, salt weathering on inorganic building materials, and weathering processes on mortars in many local- to regional-scale study areas in the Scandinavian Peninsula, the United Kingdom, Belgium, France, Italy, Greece, and Panama. Besides monitoring, the methodological approaches that are showcased include, but are not limited to, original material characterization, decay product characterization, and climate and numerical modelling on material components for assessing environmental impact and climate change effects.
