    Background and Objectives Extreme heat is an environmental health equity concern disproportionately impacting low-income older adults and people of color. Exposure factors, such as living in rental housing and lack of air conditioning, and sensitivity factors, such as chronic disease and social isolation, increase mortality risk among older adults. Older persons face multiple barriers to adaptive heat mitigation, particularly for those living in historically temperate climates. This study measures two heat vulnerability indices to identify areas and individuals most vulnerable to extreme heat and discusses opportunities to mitigate vulnerability among older adults. Research Design and Methods We constructed two heat vulnerability indices for the Portland, Oregon metropolitan area: one using area scale proxy measures extracted from existing regional data and another at the individual scale using survey data collected following the 2021 Pacific Northwest Heat Dome event. These indices were analyzed using principal component analysis (PCA) and Geographic Information Systems (GIS). Results Results indicate that the spatial distribution of areas and individuals vulnerable to extreme heat are quite different. The only area found among the most vulnerable on both indices has the largest agglomeration of age- and income-restricted rental housing in the metropolitan area

    Instrumenting Buildings to Determine Retrofit Savings: Murphy's Law Strikes Again

    Experiences with instrumentation, installation and maintenance of building energy metering systems are presented. The building energy metering was installed in a variety of locations in programs handled by the Energy Systems Laboratory at Texas A&M University. Metering typically includes monitoring for the whole-building electric load, chilled and hot water thermal loads and selected submetered electrical loads. The emphasis of the lessons learned was on the instrumentation used and installation and maintenance problems encountered during the course of the metering projects

    Cultivating Forgiveness and Compassion Through a Mindfulness-based Program for Teachers: Results from Two Field Interventions

    Get PDF
    The aim of this research was to determine if a mindfulness-training (MT) program for teachers cultivated habits of mind (e.g., mindfulness, emotion regulation, compassion and forgiveness) conducive to effective teaching. Data were gathered in two randomized control trials. Results from pre- to post-test and follow-up showed that MT was associated with increases in mindfulness, efficacy for regulating emotion on the job, and the tendency to forgive others. Linguistic analyses revealed that teachers who underwent MT expressed more positive affect when discussing their most challenging student than those in the waitlist control group. Results warrant further investigation using behavioral-, observational-, and third-person measures of these habits of mind in the target individual

    The effects of rotation and positional change of stump tissues upon morphogenesis of the regenerating axolotl limb,

    Rotation of a skin cuff 180[deg] around the proximodistal axis of the upper arm in the axolotl results in the formation of multiple regenerates in about 80[deg] of cases after amputation of the limb through the rotated skin. Rotation of the dermis or the flexor and extensor muscles folowed by amputation produced similar percentages of multiple regenerates. Rotated bone produced no abnormalities, and rotated stump epidermis was minimally effective in stimulating multiple regeneration. A thin strip of normally oriented skin interposed between a rotated skin cuff and the amputation surface blocks the morphogenetic effect of the rotated stump skin whereas removal of the normal skin between a rotated proximal skin cuff and the amputation surface allows the formation of a low percentage of multiple regenerates. Gross rotation of stump tissue components can be broken down into axial rotation per se and positional dislocation. Experiments conducted upon skin and muscle have shown that positional dislocation along the anteroposterior axis rather than axial rotation is the manipulation that leads to the formation of multiple regenerates. The first morphological indication of multiple regeneration is the appearance of a triaxial apical ridge on the blastema. Subsequently, digits form along the apical ridges.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/21931/1/0000338.pd

    Touch and look: the role of visual-haptic cues for categorical learning in children

    Benefits of synchronous presentation of multisensory compared to unisensory cues are well established. However, the generality of such findings to children’s learning with visual and haptic sensory cue pairings is unclear. Children aged six to ten years (N=180) participated in a novel table-top category learning paradigm with visual, haptic or visuo-haptic informative cues. The results indicated that combinations of complimentary visual and haptic cues facilitated learning above unisensory visual cues only in 8-year-old children. Primarily, however, haptic information was found to dominate children’s category learning across ages, particularly in the youngest children (six-year-olds), even with equal discriminability of haptic and visual exemplars. These findings suggest developmental changes in the ability to effectively combine un-related visual and haptic information for categorical learning. Implications for the use of non-pertinent visuohaptic cues in learning tasks within educational settings at different ages, and in particular the dominance of haptic stimuli for children’s learning are discussed

    Effect of physical activity, social support, and skills training on late-life emotional health: a systematic literature review and implications for public health research

    Purpose: Given that emotional health is a critical component of healthy aging, we undertook a systematic literature review to assess whether current interventions can positively affect older adults’ emotional health. Methods: A national panel of health services and mental health researchers guided the review. Eligibility criteria included community-dwelling older adult (aged ≥ 50 years) samples, reproducible interventions, and emotional health outcomes, which included multiple domains and both positive (well-being) and illness-related (anxiety) dimensions. This review focused on three types of interventions – physical activity, social support, and skills training – given their public health significance and large number of studies identified. Panel members evaluated the strength of evidence (quality and effectiveness). Results: In all, 292 articles met inclusion criteria. These included 83 exercise/physical activity, 25 social support, and 40 skills training interventions. For evidence rating, these 148 interventions were categorized into 64 pairings by intervention type and emotional health outcome, e.g., strength training targeting loneliness or social support to address mood. 83% of these pairings were rated at least fair quality. Expert panelists found sufficient evidence of effectiveness only for skills training interventions with health outcomes of decreasing anxiety and improving quality of life and self-efficacy. Due to limitations in reviewed studies, many intervention–outcome pairings yielded insufficient evidence. Conclusion: Skills training interventions improved several aspects of emotional health in community-dwelling older adults, while the effects for other outcomes and interventions lacked clear evidence. We discuss the implications and challenges in moving forward in this important area
