Exploring the Role of Action Mechanics in Game-Based Stress Recovery

Digital games can provide effective recovery from stress, with players turning to a variety of genres-including those with game mechanics that can be considered stressors themselves, i.e., action mechanics. We examine whether action mechanics undermine or facilitate game-based recovery by exposing participants (n=60) to a stress induction, and then having them play a roguelike game in one of three conditions: Combat-Required, Combat-Optional, and Combat-Free. We assess experience through self-report and observed physiological responses. Our findings suggest that gameplay-irrespective of action mechanic intensity-supports the recovery process through the pathways of experienced psychological detachment, control, dominance, and pleasure. Additionally, action mechanics were perceived by participants as particularly promising for mastery recovery experiences-but undermine the recovery pathways of relaxation, as corroborated by experienced arousal and subjective stress. Physiological measures corroborate subjective self-report. We contend that video games featuring action mechanics represent a promising strategy for stress recovery, and may be particularly beneficial in the re-assertion of mastery.

Effectiveness and safety of polyethylene-glycol-4000 versus sodium picosulphate plus magnesium oxide and citric acid for bowel cleansing before colonoscopy in children: A systematic review with meta-analysis.

Colonoscopy is performed for diagnostic and therapeutic purposes. The quality of colonoscopy depends on adequate bowel cleansing. However, there is no standardized protocol for bowel preparation in children. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to estimate the effectiveness, safety, and tolerability profile of polyethylene glycol (PEG) compared with those of sodium picosulfate (SPMC) in children. The primary sources of the reviewed studies were Scopus, PubMed, and Cochrane Library. The databases were systematically searched for RCTs comparing PEG 4000 to SPMC as a bowel cleansing solution. Six studies were included. The analysis showed that both PEG and SPMC are effective for bowel cleansing, while a split-dose regimen may be preferable to a day-before one. There were no differences between the two groups regarding adverse events such as abdominal pain, nausea, vomiting, bloating, and anal discomfort. Additionally, preparation with SPMC was preferred in terms of acceptability and compliance. Still, the need to place a nasogastric tube was significantly lower in the SPMC group compared to the PEG group and in the split dose regimen compared to the day before. In conclusion, PEG and SPMC are equally effective in obtaining an adequate bowel cleansing with a comparable adverse event rate; moreover, split-dose administration may be preferable to day-before one in terms of effective bowel cleansing. However, SPMC preparation is more acceptable seems to result in higher compliance, and to reduce the use of a nasogastric tube, that we encounter daily in clinical practice, is perceived as a stressful experience for children and their families.

Oxytocin moderates fMRI connectivity and response to implicit threat processing in cocaine use disorder

Stressful social experiences play an important role in increasing vulnerability to substance use, including cocaine. Oxytocin (OXT), known for its anxiolytic properties and involvement in social functioning, has been suggested as a potential therapeutic for cocaine use disorder (CUD). However, limited research has explored OXT’s influence on social stress in CUD, and no study has examined its effects on neural response to subconscious (implicit) social threat cues in this population. To address this gap, the present study administered intranasal OXT (24 IU) or placebo (PBO) to participants with CUD (CUD+, N = 76) or without CUD (CUD-, N = 61) in a randomized parallel design. Participants then completed a functional magnetic resonance imaging (fMRI) task involving briefly presented facial fear and anger (i.e., threat) cues, followed by neutral face stimuli. Whole-brain activation and amygdala functional connectivity (using psychophysiological interaction modeling) were examined in response to the facial threat cues. OXT reduced activation in the thalamus and pontine reticular formation in response to fear cues, and in the supplementary motor area for both fear and anger cues, regardless of CUD status. Additionally, under PBO, amygdala-medial prefrontal cortex connectivity to fear stimuli was negative for the CUD+ group, but under OXT, this coupling was positive, similar to the positive coupling observed for the CUD- group under both PBO and OXT administration. The finding of OXT-mediated reversal of amygdala-prefrontal coupling was specific to CUD+ and suggests that OXT alters circuitry related to threat surveillance and implicit emotion regulation in CUD. However, additional research is needed to determine whether these alterations due to OXT have clinical significance in CUD.

Prevalence of Anxiety and Depression among Parents of Children with Cancer-A Preliminary Study.

A child's cancer is a highly stressful experience for the entire family. Childhood cancer disrupts family functioning and is one of the most stressful and challenging events parents face, often beyond their control. Parents play a crucial role in providing emotional support to children throughout their illness, and their ability to cope can help reduce the child's negative emotions. The aim of this study was to assess the prevalence of anxiety and depression among parents of children with cancer. This cross-sectional study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines and included parents of children undergoing cancer treatment. Convenience sampling was used. The Beck Depression Inventory and the Hospital Anxiety and Depression Scale were utilized to assess the parents. This study included 270 participants (73% women, 27% men) with children at an average age of 8.75 ± 4.82 years. Diagnoses included leukemia (53%), lymphoma (29%), and other cancers. On the Beck Depression Inventory, 33% of parents were mildly depressed, 12% moderately depressed, and 32% severely depressed, with an average score of 20.63 ± 12.39 points. The HADS-M scale indicated anxiety at 48.43 ± 20.78%, depression at 45.01 ± 22.8%, and aggression at 54.72 ± 28.71%. Most parents of children with cancer have symptoms of depression and anxiety, which are influenced by the duration of the child's illness. A strong correlation was observed between the level of anxiety and the tendency for depression.

Accumbal Dopamine Responses Are Distinct between Female Rats with Active and Passive Coping Strategies.

There is a gap in existing knowledge of stress-triggered neurochemical and behavioral adaptations in females. This study was designed to explore the short-term consequences of a single social defeat (SD) on accumbal dopamine (DA) dynamics and related behaviors in female Wistar rats. During the SD procedure, rats demonstrated different stress-handling strategies, which were defined as active and passive coping. The "active" subjects expressed a significantly higher level of activity directed toward handling stress experience, while the "passive" ones showed an escalated freezing pattern. Remarkably, these opposite behavioral manifestations were negatively correlated. Twenty-four hours following the SD exposure, decreased immobility latency in the Porsolt test and cognitive augmentation in the new object recognition evaluation were evident, along with an increase in electrically evoked mesolimbic DA release in passive coping rats. Rats exhibiting an active pattern of responses showed insignificant changes in immobility and cognitive performance as well as in evoked mesolimbic DA response. Furthermore, the dynamics of the decline and recovery of DA efflux under the depletion protocol were significantly altered in the passive but not active female rats. Taken together, these data suggest that female rats with a passive coping strategy are more susceptible to developing behavioral and neurochemical alterations within 24 h after stress exposure. This observation may represent both maladaptive and protective responses of an organism on a short timescale.

Gender Disparities in Workplace Stress Levels Among Physicians and Nurses

Work stress is increasingly recognized as a critical health concern that negatively impacts employee satisfaction and productivity, leading to elevated absenteeism and turnover rates. Studies suggest that women may face higher levels of work-related stress than men, although some research has not identified significant differences. The experiences of stress in the workplace differ between doctors and nurses, given the higher levels of interpersonal interaction in these roles. This cross-sectional observational study involved 200 doctors and 200 nurses, ensuring balanced gender representation. Demographic information was collected through a semi-structured proforma, and workplace stress was assessed using the Workplace Stress Scale. The results indicated that 66.2% of participants viewed their work environment as stressful, with a mean score of 19.01 on the Workplace Stress Scale. A notably higher proportion of females (72.5%) reported experiencing stress at work compared to males (60.5%, p<0.05). Among the nursing staff, female nurses reported the highest stress levels (76%, mean score of 21.3), followed by female doctors (69%, mean score of 19.4), while male nurses (61%, mean score of 18.1) and male doctors (60%, mean score of 17.2) reported lower levels. These findings suggest that women perceive their work environments as significantly more stressful than their male counterparts. It is crucial to focus on enhancing working conditions for doctors and nurses, especially for female employees, as this can lead to improved outcomes for patients and the wider community.

How to give an effective conference presentation.

At some point in their careers, nurses may choose or be invited to give a conference presentation, online or in person. For some, this can be an exciting opportunity to share best practice, impart knowledge and receive feedback, for example, on a local service initiative they have been involved in. For others, it can be a stressful experience, especially if they are not confident in presenting. However, giving conference presentations is an important skill in nursing leadership, particularly when sharing a new method of care or innovative service. Although there is no specific evidence base underlying conference presentation, expert recommendations indicate that a well-delivered presentation relies on thorough preparation, an avoidance of excessive on-screen text and the use of images and key messages to ensure the audience gains maximum benefit. • When preparing a presentation, you should consider aspects such as what the conference organisers require, the time allocated for the presentation and how to prepare the appropriate number of clear and well-presented slides. • Consider the key points that you wish to communicate to the audience and use a balanced mix of text and images. • Maintain a focus on the presentation's application to nursing practice, so that audience members can take away key learning points and apply these to their own practice. REFLECTIVE ACTIVITY: 'How to' articles can help to update your practice and ensure it remains evidence based. Apply this article to your practice. Reflect on and write a short account of: • How this article might improve your presentation skills. • How you could use this information to educate nursing students or other colleagues about effective conference presentation.

Evaluating the Effects of Motion Cues in Virtual Truck Driver Training

The integration of simulation technology into professional training has transformed learning in various sectors. Although prior research has explored motion cueing in simulators such as aviation training, driver navigation and performance, there is limited investigation into the impact of motion stimuli in VR-based truck driver training. This study investigates the driving performance of truck drivers in two virtual driving tasks, comparing conditions with and without motion cues. Participants wore virtual reality headsets and were situated within an immersive motion simulator. They completed two driving tasks involving truck docking and highway driving. Simulator sickness, stress, and user experience were assessed using the simulator sickness questionnaire, subjective unit of distress scale, and user experience questionnaire, respectively. Our findings suggest that motion cues hold potential to enhance subjective experiences, making driving more engaging, stimulating, and mitigating motion sickness. However, they did not significantly affect overall driving performance, except for steering behavior. Participants exhibited more engaged steering during highway driving when motion cues were present. Our findings suggest that the impact of motion cues is task-dependent, with their absence not showing a significant detrimental effect on driving performance in the simulated environment. Further validation with field-observed data is necessary to confirm these findings. These insights can guide future policies and regulations governing virtual truck driver training, ultimately ensuring improved safety and performance in the industry.

Silent Effects of the COVID-19 Pandemic: Parental Attachment in Pediatric Patients.

The COVID-19 pandemic led to isolation measures intended to curb the spread of infection, which are believed to have negatively affected children's psychological well-being. This study examines the impact of the pandemic on parental attachment with children. A cross-sectional study was conducted with children visiting a general pediatrics clinic between April 1 and 20, 2023. Their COVID-19 infection history was recorded, and the Kern's Attachment Questionnaire was used to assess parental attachment in children who had contracted COVID-19 and those who had not. The study involved 716 patients aged 9-12, divided into two groups: those who had contracted COVID-19 (n=253) and those who had not (n=463). Kern's Attachment Questionnaire scores for mothers were 46.3 for children with COVID-19 and 49.4 for those without. For fathers, the scores were 43.9 and 48, respectively. Children who had contracted COVID-19 showed significantly lower attachment scores to both mothers and fathers compared to the control group (p=0.04, p=0.00). The pandemic's long-term biopsychosocial effects are evident, with increased stress and negative experiences posing risks to child development, particularly in terms of parental attachment. While early attachment begins in infancy, it continues to evolve. This study underscores the need for behavioral and psychological follow-up for adolescents in the post-pandemic period.

Improving Outcomes for ICU Family Members: The Role of Spiritual Care.

Having a family member hospitalized in the intensive care unit (ICU) can be a stressful experience for family members, encompassing both psychological and spiritual distress. With over 5 million ICU admissions annually in the United States, it is imperative to enhance the experiences and coping mechanisms of ICU family members. In particularly challenging situations, some family members even face psychological effects known as post-intensive care syndrome-family, which includes anxiety, depression, and posttraumatic stress. The distress may be worsened when patients and families experience poor communication or medical care, which has been shown to be more common among minoritized populations including Black and Hispanic patients and families. Family members' emotional and spiritual distress also has an effect on the medical decisions they make for the patient. While research has delved into the impact of spiritual care for ICU family members, further investigation is still needed to determine the most effective approaches for delivering such care. This narrative review will describe a conceptual model aimed at guiding future research in this endeavor. The model proposes that chaplains provide emotional, spiritual, and information support to ICU family members. This affects both their ICU experience, decision making, and outcomes for the patient and family. This process is also affected by characteristics of the family such as race, ethnicity, and economic status. This model helps identify gaps in research, including the need for randomized trials of spiritual care that identify mechanisms underlying outcomes and demonstrate impact of spiritual care, and consider race, ethnicity, and other characteristics.

Secondary Traumatic Stress and Coping Experiences in Psychiatric Nurses Caring for Trauma Victims: APhenomenological Study.

In this study, it was aimed to evaluate the secondary traumatic stress and coping experiences of psychiatric nurses who care for people who have experienced psychological trauma with a phenomenological approach. In this study, semi-structured in-depth interviews were conducted with 18 psychiatric nurses residing in Turkey using the phenomenological research method. The criterion sampling method was used to reach the sample group. Interviews continued until data saturation was achieved, and all interviews were audio-recorded and then transcribed. The data were analysed using thematic analysis. The study was conducted and reported using the COREQ checklist. In the analysis of the data, three themes (difficulties in caring for people who have experienced trauma, the effects of caring for people who have experienced trauma on the individual and coping, reflections of secondary trauma on the profession) and seven sub-themes (mental, physical, social, psychosocial difficulties and coping, quality of care, professional and organisational aspects) were identified. As a result of the study, it was determined that secondary traumatic stress was observed in psychiatric nurses caring for individuals who experienced psychological trauma. It was determined that caring for people who have experienced psychological trauma can negatively affect nurses psychosocially, and individuals have difficulty coping. In line with the results of the study, it is thought that necessary intervention programs should be created for nurses experiencing secondary traumatic stress.

Cutting the Gordian knot of the education ‘crisis’ with teacher testing. A blunt instrument that crushes marginalised pre-service teachers

ABSTRACT This paper offers a brief yet evocative glimpse into marginalised pre-service teachers’ (PST) experiences of teacher testing in Australia’s High-stakes Literacy and Numeracy Test for Initial Teacher Education Students (LANTITE). Utilising Critical Disability Theory (CDT)in particular, Goodley’s (2016) concept of neoliberal-ableism, we problematise teacher testing as a gatekeeping tool for students undertaking teacher education. The article highlights how neoliberal education policies in Australia have disempowered and turned away talented and empathetic future teachers. By illuminating their embodied experiences of stress and anxiety, we interrogate neoliberal discourses of power and how teacher testing is used as a blunt instrument to solve complex problems and funnel public funding to private corporations. As part of a larger longitudinal research project, we offer four narrative portraits giving voice to vulnerable PSTs who have become unwitting victims of the high-stakes test juggernaut. This article focuses on five emergent themes from the research: (a) the embodied impact of stress and anxiety on test-takers, (b) withholding of information regarding testing processes and support, (c) the lack of differentiation available to PSTs (d) impacts of edu-businesses and the business of education on vulnerable participants and (e) a passion for differentiation.

Contextualizing experiences of cultural stress: A qualitative exploration among Hispanic/Latinx youth in Miami and Los Angeles.

Hispanic/Latinx youth vary in their immigration heritage (e.g., country of origin, familial migration history, etc.) and the structure of their communities. This study is a qualitative exploration of Hispanic/Latinx youth experiences of cultural stress in Miami and Los Angeles in 2021. A total of 23 Hispanic/Latinx adolescents in Los Angeles (n = 12) and Miami (n = 11) provided in-depth interviews to assess: (a) appraisals of family immigration history and (b) experiences across three cultural stressors: sociopolitical, language brokering, and intragroup marginalization. Interviews were analyzed using a general inductive analytic approach and case comparison methodology to assess differences across sites. For appraisals of family immigration history, gratitude and hope emerged as positive emotions experienced when youth reflected on their immigrant origins. Miami participants reported perceived worsening of sociopolitical stress as a result of changes in political administration whereas participants in Los Angeles felt a sense of relief. Participants in Miami and Los Angeles reported similar strengths and challenges in language brokering with COVID-19 variedly impacting youth's perceived language brokering stress. Last, to youth intragroup marginalization experienced from family members was experienced as more detrimental than from peers, and they reported the use of cognitive reframes to cope. Cultural stressors are dynamic and diverse. This study further informs cultural stress theory by cataloging how families' immigration history and national current events inform experiences of stress among youth.

Talking to Unconscious? - Therapeutic Communication During General Anaesthesia, Resuscitation and Therapy of Coma

There are numerous reports from patients concerning perceptions during deep unconsciousness, be it general anaesthesia, cardiopulmonary resuscitation or intensive care and coma treatment. These experiences can cause considerable traumatisation. The most stressful experience is apparently not feeling pain, but the lack of communication, i.e. being recognised and being able to express oneself. Although there are already indications of positive effects of positive communication during general anaesthesia, these findings have not yet markedly changed the way we deal with the unconscious.

Stress produces negative judgement bias in cuttlefish.

Judgement bias tasks (JBTs) are used to assess the emotional state and welfare of animals in zoos, farms and laboratories, based on the interpretation of an ambiguous or intermediate cue. Animals in positive affective states are more likely to interpret the ambiguous cue positively, whereas animals experiencing negative affect are more likely to interpret ambiguous cues pessimistically. Here, we developed a modified JBT assay for the stumpy-spined cuttlefish, Sepia bandensis, to determine whether cuttlefish exhibit negative affective states resulting from external stressors. Positive and neutral visual cues were presented twice daily until animals learned to associate food with the reinforced visual cue. After training, one treatment group was exposed to combined exposure and handling stress produced by 6 days of impoverished housing and simulated net capture. Our control group received no stress experience. In test trials performed after the stress experience, stressed animals showed higher latencies to approach ambiguous cues, spent significantly less time in rooms with ambiguous cues once they entered, and were less likely to enter first into the ambiguous cue-paired room compared with controls. These behaviours suggest that stress induces pessimistic judgement bias in cuttlefish, the first indication of this capacity in cephalopods.

Mental health screening for parents following surgical neonatal intensive care unit (NICU) discharge

Admission to the surgical neonatal intensive care unit (sNICU) is a stressful experience. Care is often complex, with inherent risks and potential complications. This study describes the implementation of an outpatient mental health screening process for parents of infants admitted to a sNICU. Parents of infants aged >34 weeks gestation with a congenital anomaly requiring neonatal surgery participated in this prospective observational study. Standardised measures to screen for parenting stress (Parenting Stress Index™ Fourth Edition Short Form) and depressive symptoms (Center for Epidemiologic Studies Depression Scale) were administered at the first outpatient visit scheduled when the infant's corrected gestational age was 4 months. A triage algorithm was developed, to review the initial screening results prompting appropriate action and intervention. Positive screens were triaged as evaluate (assess within 48 h), targeted information (email contact), or escalate response (same day risk assessment). Demographic factors associated with parental stress and depressive symptoms were explored. Forty parents (response rate: 88 %) participated in screening. A high portion of parents (52.5 %) required secondary screening, for parenting stress (n = 10), depressive symptoms (n = 5) or both stress and depressive symptoms (n = 6). Socioeconomic disadvantage was positively associated with parenting stress (p = 0.02) and greater depressive symptoms with parent education levels (p = 0.01). Results indicate screening of parent mental health in the outpatient setting is feasible. Use of a triage algorithm helped prioritise parent follow-up and facilitate workflows. Parent mental health screening should be prioritised within and beyond the sNICU to support family and infant outcomes during this critical period of development.

A small population of stress-responsive neurons in the hypothalamus-habenula circuit mediates development of depression-like behavior in mice.

Accumulating evidence has shown that various brain functions are associated with experience-activated neuronal ensembles. However, whether such neuronal ensembles are engaged in the pathogenesis of stress-induced depression remains elusive. Utilizing activity-dependent viral strategies in mice, we identified a small population of stress-responsive neurons, primarily located in the middle part of the lateral hypothalamus (mLH) and the medial part of the lateral habenula (LHbM). These neurons serve as "starter cells" to transmit stress-related information and mediate the development of depression-like behaviors during chronic stress. Starter cells in the mLH and LHbM form dominant connections, which are selectively potentiated by chronic stress. Silencing these connections during chronic stress prevents the development of depression-like behaviors, whereas activating these connections directly elicits depression-like behaviors without stress experience. Collectively, our findings dissect a core functional unit within the LH-LHb circuit that mediates the development of depression-like behaviors in mice.

Secondary traumatization in refugee care—EMDR intervention for interpreters (STEIN): a study protocol for a quasi-randomized controlled trial

BackgroundBy the end of 2022, more than 100 million people worldwide fled their homes. Before, during and after their flight, refugees have high risk of experiencing traumatic events. Accordingly, around every third refugee is affected by posttraumatic stress disorder. For adequate mental health care, the service of interpreters is often urgently needed to overcome existing language barriers. However, repeated exposure with details of traumatic narratives, as experienced by interpreters, can be burdensome and can lead to trauma sequela symptoms in terms of secondary traumatic stress. Only few studies have examined the treatment of secondary traumatic stress to date. Based on the recommendations for the treatment of posttraumatic stress disorder with confrontational methods, this study was designed to evaluate the effectiveness of an eye movement desensitization and reprocessing (EMDR) intervention in a sample of interpreters working in refugee care suffering from secondary traumatic stress symptoms.MethodsTo evaluate the effectiveness of an EMDR intervention for the treatment of secondary traumatic stress symptoms, a quasi-randomized controlled trial using a waiting group design will be performed. Participants will be treated with a maximum of 6 sessions based on EMDR standard protocol. Primary outcome is the symptom load of secondary traumatic stress, assessed with the Questionnaire for Secondary Traumatization, while secondary outcomes comprise further symptom complexes such as PTSD due to self-experienced traumatic events, depression, anxiety, and somatization as well as quality of life, quality of professional life, and psychological wellbeing that will be assessed with the PDS, PHQ-9, GAD-7, SSD-12, SF-12, PROQOL-5, and WHO-5, respectively.DiscussionOur primary interest is to determine the efficacy of an EMDR intervention in interpreters affected by secondary traumatic stress, especially how many sessions are needed for significant symptom reduction. Change of associated symptom complexes and quality of life will be investigated. Reprocessing one’s own stressful experiences may also contribute to this, which is not the focus of the treatment but relevant to the EMDR protocol. This study aims to assess if EMDR could be an acceptable, effective, and time-efficient method for reducing work-related secondary traumatization.Trial registrationGerman Clinical Trials Register, DRKS00032092, registered 16 June 2023.

Stepping back or stepping in: A qualitative investigation of self-distanced versus self-immersed stressor reflections with competitive swimmers.

High performance sport consists of stressor events which can disrupt an athletes' functioning and negatively influence performance. The way in which one reflects upon stressor events and develops insights regarding how they coped is essential to overcoming similar experiences in the future. We conducted a pilot randomised controlled trial with a qualitative analysis to explore the coping insights among 48 highly trained/national level swimmers in the lead up to major swimming competitions, who reflected on stressor events from self-distanced or self-immersed perspectives over a 3-week period. Using the self-reflection and coping insight framework as a guideline, we captured diverscoping insights across both groups. Irrespective of the group to which they were assigned, athletes showed positive signs towards re-interpreting their stressor experience and embracing the stressor event, whereas consideration of individual values and adoption of a future-focus viewpoint were areas lacking. The emotionality described by athletes in their written reflections varied across both groups and influenced the development of coping insights. Our findings indicate a necessity to examine the emotionality associated with unique stressor events and consider integrating reflection strategies, while also enhancing the operational definitions within conceptual models of stress reflection protocols.

A WRF-UCM-SOLWEIG framework for mapping thermal comfort and quantifying urban climate drivers: Advancing spatial and temporal resolutions at city scale

The capability to evaluate city-scale outdoor thermal comfort is crucial for understanding the public's experience of heat stress, especially during heat waves. Nevertheless, there remains a methodological gap in accurately mapping thermal comfort with high spatial and temporal resolutions in complex urban environment and in quantifying the contributions of various urban climate drivers, such as sky view factors and tree canopy fraction. To bridge this gap, we propose an innovative WRF-UCM-SOLWEIG framework that couples a mesoscale model with an urban microclimate model. Specifically, it integrates the Weather Research and Forecasting model coupled with the urban canopy model (WRF-UCM) and the Solar and Longwave Environmental Irradiance Geometry model (SOLWEIG). This framework is then applied to a densely populated tropical city in China, to quantify the impact of urban climate drivers on the Universal Thermal Climate Index (UTCI). The results reveal a significant diurnal variation in the impact of urban morphology. Notably, the most significant drivers affecting daytime UTCI are the impervious surface fraction and the tree canopy fraction, with maximum Pearson's correlation coefficients of 0.80 and -0.70, respectively. These findings suggest that urban heat mitigation strategies should prioritize on reducing impervious surfaces and enhancing shade management, alongside expanding urban forestry measures.
