Summary: This study found that around 40.4% of students did not like to go to school alone and wanted someone from their family to accompany them. Additionally, about one quarter of students expressed fear of traffic and their inability to deal with it. Only 80.9% of students received some form of road safety training, with parents and schools being the major sources of this information. Ages under 14 and lower levels of mother's education were significant contributors to poor road crossing habits among students.

Summary: The actual pathways used by cyclists, pedestrians, and users of micromobility at intersections may differ from those planned by traffic engineers. By observing usage patterns, a Python tool using clustering is introduced to identify the pathways used by road users. The tool was applied to intersections in Germany, with exemplars selected to represent different pathway types. The open-source Python tool RoadUserPathways is presented along with case studies and use cases.

Summary: Gray wolf recovery and conservation in the United States has been remarkably successful over the past 30 years. However, as wolf populations expand, they will encounter challenges such as fragmented habitats, barriers to dispersal, and increased conflicts with humans, pets, and livestock. We summarize the major scientific and social challenges that will be faced in wolf conservation and suggest actions to address each challenge.

Summary: Decades of industrial resource extraction in boreal forests have led to the fragmentation of wildlife habitats due to linear features, highlighting the importance of decommissioning these features and restoring suitable habitats. Research on forest road use by gray wolves, black bears, and moose found that road-scale characteristics such as surrounding wetlands, lateral cover density, age of roads, and surrounding vegetation influence their use patterns.

Summary: This study used snow tracking data to estimate suitable habitat for gray wolves in the eastern USA and found that wolves tend to avoid areas with high human population densities and agricultural land. The study also identified five unoccupied areas where wolves could establish viable populations. These areas are limited in connectivity with current wolf range due to the Great Lakes and extensive agriculture in the Midwest USA.

Summary: In this study, the analysis and optimization of machining parameters in the ball burnishing process of AISI O2 hardened steel were conducted. The surface roughness was controlled by factors such as initial roughness, ball diameter, burnishing force, burnishing speed, and burnishing feed. Taguchi's L-36 orthogonal array was employed to reduce the number of experiments. A mathematical prediction model was developed using response surface methodology (RSM) to analyze the interactions among the control factors. Gray wolf optimization (GWO) algorithm was used to obtain the optimum control factors, and confirmation experiments were performed for validation.

Summary: Emissions from non-road construction machinery (NRCM) have a significant impact on air quality. A study in Wuhan analyzed six typical NRCM using a portable emission measurement system (PEMS) to estimate real-world emission characteristics and chemical composition of PM2.5. The study found high levels of carbon monoxide, hydrocarbon, nitrogen oxides, and particulate matter, indicating the need for stronger regulation of NOx emission in Wuhan. The composition of PM2.5 emitted from NRCM was dominated by organic carbon and elemental carbon, followed by water-soluble ions and elements.

Summary: Climate change has caused longer fire seasons and more intense wildfires worldwide, leading to significant economic and environmental impacts. A study conducted in Southwest China evaluated the effectiveness of different fuel treatment designs in mitigating wildfire risk under varying fire severity conditions. The results showed that fuel treatments were effective in reducing risk under low and normal fire severity scenarios, but their effectiveness was limited under high fire severity conditions.

Summary: Appleton's prospect-refuge theory suggests that the presence of dense vegetation, topography, and people in a park can influence the safety and privacy felt by visitors in different ways. This study aimed to understand the relationship between observation point height, vegetation location, presence of other people, and perceived privacy and safety. The results showed that flat or lower ground without the presence of others was considered the safest, while landscapes higher up with dense vegetation and no other people were rated highest in terms of privacy. The findings have practical implications in terms of providing privacy without compromising safety.

Summary: This study investigated the influence of urban greenspace spatial morphology on non-communicable diseases and found that neighborhoods with more connected, aggregated, coherent, and complex-shaped greenspace had a lower prevalence of these diseases. Such associations were mediated by air pollution and physical inactivity. The results suggest that the spatial morphology of designed urban greenspace plays a significant role in neighborhood health.

Summary: Developing a green infrastructure is an important environmental policy goal in many countries around the world. Different countries have different requirements on the spatial allocation of conservation sites for green infrastructure. Price-type and procedural instruments are commonly used, but the utilization of incentive mechanisms that internalize the benefit of clustering is relatively low. There is a need for more studies on incentive mechanisms and green infrastructure policies in the global South.

Summary: Observational and experimental studies have shown that exposure to greenness is beneficial for long-term health and well-being. However, more evidence is needed regarding the short-term health impacts of nearby nature in urban areas. This study used immersive virtual reality technology to investigate how transitions between built and natural environments affect urban residents. Results showed that transitioning from built to natural environments led to reductions in negative mood and transient anxiety, while transitions from natural to built environments had the opposite effect. Additionally, participants showed more emotional responses to nature through physiological measures. The study also highlighted the influence of contextual factors, such as physical health conditions, stress levels, experience with nature, and growth environments, on stress recovery. Overall, this study provides empirical evidence supporting the promotion of nearby nature in urban built environments.

Summary: This study examines climate justice in the Ecuadorian Amazon Region (EAR), highlighting the multiple injustices caused by oil extraction activities. Using spatial analysis, the study shows that the EAR has been a major producer of oil since 1972, leading to environmental impacts such as oil spills and pollution. The results emphasize the need to include these territories in climate justice discussions and promote the rights to a non-toxic environment.

Summary: Vegetation barriers are an effective strategy in urban planning to mitigate traffic-induced air pollution and reduce exposure. This study uses field measurements and numerical modeling to show that constructing vegetation barriers with short bushes can effectively reduce PM2.5 pollution in open-road environments, while higher coverage of tall bushes may worsen the pollution.
