AbstractThis article presents findings from TechTales, a participatory design research (PDR) project where learning scientists, public library staff members, informal science educators, and staff members from Native-American-serving organizations collaborated to design a family-based robotics workshop that was grounded in storytelling. We approach this by engaging Indigenous ways of knowing and being from a sociocultural learning theory perspective. Through analyzing families-in-interaction as they constructed dioramas with robotics that told their family stories, we explore how cultivating consequential learning environments in STEM is intimately intertwined with historicity, knowledge systems, and the agentic positioning of learners to design new technologies. We find that using storywork as the design focus of building dioramas created learning environments where computer programing and robotics became dynamic tools toward family-making, collaboration, and the active presencing of Indigenous knowledge systems and cultural practices. Living and interrelating with story and its knowledge systems through making were enactments of Indigenous resurgence in everyday ways. From a structure of social practices perspective, this opens up learning spaces for engagement in STEM-Art practices and in relation to other social practices of consequence, such as cultural flourishing and affiliation, collaboration and family-making, and societal repositioning. 相似文献

Background/ObjectiveThe aim of the study was to analyze the relationship between being bullied and the physical fitness components, and to determine whether a healthy physical fitness level is related with lower victimization in children and adolescents with overweight and obesity compared to unfit overweight/obese peers. Method:The present cross-sectional study included a total of 7,714 youths (9-17 years), categorized as normal-weight or overweight/obese and fit or unfit according to sex-specific handgrip strength and cardiorespiratory fitness (CRF) cut-points. Bullying (physical, verbal, social exclusion, sexual harassment, and cyberbullying) was assessed through the Standard Health Behavior in School-aged Children survey questions. Results:Boys and girls that were categorized as fit (healthy level of CRF) showed lower traditional bullying compared to unfit counterparts. Also, a healthy level of CRF could be a protective factor of traditional bullying among overweight/obese youths compared to unfit overweight/obese peers. Conclusions:CRF is related with lower risk for experiencing traditional bullying in Latino youths with and without obesity, thus emphasizing the role of fitness even among youth with excess of adiposity. 相似文献

This study investigated the relationship between guilt and well‐being of bereaved persons, and explored potential differences in the associations between guilt‐complicated grief (CG) and guilt‐depression. In total, 1358 Chinese bereaved adults were recruited to fill out questionnaires. Participants (N = 194) who had been bereaved within 2 years of the first survey, filled out the same questionnaires 1 year later. Higher guilt was associated with higher degrees of both CG and depression. The level of guilt predicted CG and depression symptoms 1 year later. Bereavement‐related guilt has a closer association with CG than depression. Responsibility guilt, indebtedness guilt and degree of guilt feeling are more prominent aspects of guilt in CG than in depression. These findings demonstrate the significant role of guilt (perhaps a core symptom) in mental health of the bereaved, having implications for identifying persons with grief complications and depression. 相似文献

Both substance dependence and depressive mood seem to be associated with increased suicide risk. Clinical information on suicide attempts and depressive symptoms were obtained from a sample of 211 psychoactive substance dependents attending a university clinic program for addicts in Brazil. 49 subjects (23.4%) had attempted suicide at least once, and the frequency of reporting attempts was 4.32 times greater among women than among men. Male addicts also tended to engage in potentially more dangerous attempt methods than women. Depressive male addicts were 2.17 times more likely to have attempted suicide than nondepressive addicted men. Among women, no association could be established between having attempted suicide and the presence of depression. Substance addicts have a relatively high risk of attempting suicide and the co-occurrence of depression seems to increase prevalence of suicidal behavior among men. 相似文献

This research examines how the weighting of an attribute is jointly affected by attribute precision and decision stage. Building on prior work suggesting (a) that less (more) precise numerical values are easier to process (more accurate), (b) that decision‐makers' motivation to be efficient (accurate) is greater when creating a consideration set (making a final choice), and (c) that decision‐makers tend to overweight information that is compatible with their goals, we hypothesize that when creating a consideration set (making a choice) participants tend to assign greater weight to less (more) precise attributes. Five studies (two of them reported in the Appendix S1) offer triangulating evidence for these predictions. Overall, this work contributes to research on numerical cognition, efficiency versus accuracy trade‐offs, attribute weighting, and two‐stage decisions. 相似文献

This research paper addresses the endemic dimensions of having or not having a good life using a concept of poverty based on self-reported subjective well-being. We build a subjective well-being poverty (SWBP) line and compare it with two income poverty (IP) lines. The endemic dimension comes from rural Ecuador and the indigenous happiness idea of Buen Vivir (Living Well), which has been the focus of growing attention in the scientific and the political arena. Discrepancies between SWBP and IP are deeply explored building models that explain SWBP with IP, as well as control variables and Buen Vivir related variables. We show that income poor households are more likely to be poor in terms of their reported subjective well-being. However, households that grow their own food and are in an indigenous community are less likely to report to be subjective well-being poor. The results suggest that low SWBP values in contrast with high IP may be explained by idiosyncratic components of the Buen Vivir philosophy. The components of the Buen Vivir ethos related to SWBP give rise to the idea of building multidimensional concepts of poverty based on what ethnic people consider to be good or bad for their specific way of life. In a general context, our study raises the importance of considering poverty and its dimensions taking into account the endemic factors of specific groups of people and cultures. That is, to take into account what is important for their lives. 相似文献

In developmental research, the relationship between Executive Function (EF) and Theory of Mind (ToM) has been extensively assessed, and EF has been considered a condition for ToM. However, few researchers have studied the relationship between EF and ToM in clinical populations, especially that of Attention Deficit Hyperactivity Disorder (ADHD), a neurodevelopmental disorder characterized by symptoms of inattention and motor hyperactivity/impulsivity, in which EF is largely impaired. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model, 201 English and Spanish articles evaluating EF and ToM in ADHD were chosen. Fifteen papers met the inclusion criteria and were selected for further analysis. The first study dates from 2001. Most of the studies’ designs are cross-sectional, include mostly male children, have a small sample size, and were conducted in European countries. Unlike tasks assessing EF, tasks assessing ToM were heterogeneous across studies. The EFs most correlated with ToM were inhibitory control, working memory, cognitive flexibility, and attention. Interest in studying the relationship between EF and ToM in ADHD is recent,but increasing based on new findings and tuning of ToM instruments. However, while an association between EF and ToM is indicated in ADHD, the degree of prediction and predictability of one over the other cannot yet be established because of the studies’ heterogeneity. 相似文献

Healthy older adults typically perform worse than younger adults at rule-based category learning, but better than patients with Alzheimer’s or Parkinson’s disease. To further investigate aging’s effect on rule-based category learning, we monitored event-related potentials (ERPs) while younger and neuropsychologically typical older adults performed a visual category-learning task with a rule-based category structure and trial-by-trial feedback. Using these procedures, we previously identified ERPs sensitive to categorization strategy and accuracy in young participants. In addition, previous studies have demonstrated the importance of neural processing in the prefrontal cortex and the medial temporal lobe for this task. In this study, older adults showed lower accuracy and longer response times than younger adults, but there were two distinct subgroups of older adults. One subgroup showed near-chance performance throughout the procedure, never categorizing accurately. The other subgroup reached asymptotic accuracy that was equivalent to that in younger adults, although they categorized more slowly. These two subgroups were further distinguished via ERPs. Consistent with the compensation theory of cognitive aging, older adults who successfully learned showed larger frontal ERPs when compared with younger adults. Recruitment of prefrontal resources may have improved performance while slowing response times. Additionally, correlations of feedback-locked P300 amplitudes with category-learning accuracy differentiated successful younger and older adults. Overall, the results suggest that the ability to adapt one’s behavior in response to feedback during learning varies across older individuals, and that the failure of some to adapt their behavior may reflect inadequate engagement of prefrontal cortex. 相似文献
