Increasing the Amount of Time EBD Identified Students Spend in the Classroom

This action research paper focuses on educating children in their least restrictiveenvironment. This study was conducted in an elementary school in St. Paul where thedistrict is pushing towards full inclusion. The data specifically looks at two fifth gradestudents, both with Emotional Behavioral Disorders. Data sources included a parentquestionnaire, pre and post student questionnaire, teacher journal and observations, anexcel spreadsheet behavior checklist, and a check-in log for the school’s behavior room.Results showed that both students were able to increase their amount of time spent in the general education classroom setting. Data also supported that both students, and their respective parent, wanted them to have increased inclusion time. The results indicate that increased inclusion for EBD students is possible and should be carried out so that each child is being taught in their least restrictive environment. Further research may indicate more or less inclusion time based on longer duration of study and more students participating

Regular, brief mindfulness meditation practice improves electrophysiological markers of attentional control

Mindfulness-based meditation practices involve various attentional skills, including the ability to sustain and focus ones attention. During a simple mindful breathing practice, sustained attention is required to maintain focus on the breath while cognitive control is required to detect mind wandering. We thus hypothesized that regular, brief mindfulness training would result in improvements in the self-regulation of attention and foster changes in neuronal activity related to attentional control. A longitudinal randomized control group EEG study was conducted. At baseline (T1), 40 meditation naïve participants were randomized into a wait list group and a meditation group, who received three hours mindfulness meditation training. Twenty-eight participants remained in the final analysis. At T1, after eight weeks (T2) and after 16 weeks (T3), all participants performed a computerized Stroop task (a measure of attentional control) while the 64-channel EEG was recorded. Between T1 and T3 the meditators were requested to meditate daily for 10 min. Event-related potential (ERP) analysis highlighted two between group effects that developed over the course of the 16-week mindfulness training. An early effect at left and right posterior sites 160–240 ms post-stimulus indicated that meditation practice improved the focusing of attentional resources. A second effect at central posterior sites 310–380 ms post-stimulus reflects that meditation practice reduced the recruitment of resources during object recognition processes, especially for incongruent stimuli. Scalp topographies and source analyses (Variable Resolution Electromagnetic Tomography, VARETA) indicate relevant changes in neural sources, pertaining to left medial and lateral occipitotemporal areas for the early effect and right lateral occipitotemporal and inferior temporal areas for the later effect. The results suggest that mindfulness meditation may alter the efficiency of allocating cognitive resources, leading to improved self-regulation of attention

Payer le prix? Conciliation travail universitaire et famille pendant la pandémie de la COVID-19

Introduction: The shift to remote working/learning to slow transmission of the SARS-CoV-2 virus has had widespread mental health impacts. We aimed to describe how the COVID-19 pandemic impacted the mental health of students and faculty within a health sciences faculty at a central Canadian university. Methods: Via an online survey, we queried mental health in the first four months of the COVID-19 pandemic quantitatively (scale: 1 (most negative)-100 (most positive)) and qualitatively. Results: The sample (n = 110) was predominantly women (faculty 39/59; [66.1%]; students 46/50; [92.0%]). Most faculty were married/common law (50/60; [84.8%]) and had children at home (36/60; [60.0%]); the opposite was true for most students.  Faculty and students self-reported comparable mental health (40.47±24.26 and 37.62±26.13; respectively). Amongst women, those with vs. without children at home, reported significantly worse mental health impacts (31.78±23.68 vs. 44.29±27.98; respectively, p = 0.032). Qualitative themes included: “Sharing resources,” “spending money,” “few changes,” for those without children at home; “working at home can be isolating,” including the subtheme, “balancing act”: “working in isolation,” “working more,” for those with children at home. Discussion: Amongst women in academia, including both students and faculty, those with children at home have disproportionately worse mental health than those without children at home.Introduction : Le virage vers le travail et l’enseignement à distance pour ralentir la transmission du virus SRAS-CoV-2 a eu des répercussions étendues sur la santé mentale. Notre étude vise à décrie l’impact de la pandémie de la COVID-19 sur la santé mentale des étudiants et du corps professoral au sein Faculté des sciences de la santé d’une université du centre du Canada. Méthodes : Un questionnaire en ligne a été administré pour récolter des données qualitatives et quantitatives (échelle : de 1 [le plus négatif] à 100 [le plus positif] à l’égard de la santé mentale des participants au cours des quatre premiers mois de la pandémie. Résultats : L’échantillonnage (n = 110) était majoritairement composé de femmes (membres du corps professoral : 39/59 ou 66,1 %; étudiantes 46/50 ou 92,0 %). La plupart des répondants du corps professoral étaient mariés ou en union libre (50/60 ou 84,8 %) et avaient des enfants à la maison (36/60 ou 60,0 %). Le contraire était vrai pour la plupart des étudiants. L’état de santé mentale déclaré par le corps professoral et les étudiants était comparable (40,47±24,26 et 37,62±26,13 respectivement). Parmi les femmes, autant celles qui avaient des enfants à la maison que celles qui n’en avaient pas, ont déclaré que leur santé mentale était nettement moins bonne (31,78±23,68 contre 44,29±27,98 respectivement; p = 0,032). Pendant l’analyse des données qualitatives, on a identifié les thèmes « le partage de ressources », « les dépenses » et « peu de changements » pour les répondants qui n’avaient pas d’enfants à la maison alors que les thème « le télétravail accentue l’isolement », ainsi que lessous-thèmes « maintien de l’équilibre : travailler en isolement’’ et ‘’travailler plus » ont émergé pour ceux qui avaient des enfants à la maison. Discussion : Parmi les femmes œuvrant dans le milieu universitaire, qu’elles soient étudiantes ou membres du corps professoral, la santé mentale de celles qui ont des enfants à la maison est davantage affectée que celle des femmes qui n’en ont pas

A systematic experimental neuropsychological investigation of the functional integrity of working memory circuits in major depression

Verbal and visuospatial working memory (WM) impairment is a well-documented finding in psychiatric patients suffering from major psychoses such as schizophrenia or bipolar affective disorder. However, in major depression (MDD) the literature on the presence and the extent of WM deficits is inconsistent. The use of a multitude of different WM tasks most of which lack process-specificity may have contributed to these inconsistencies. Eighteen MDD patients and 18 healthy controls matched with regard to age, gender and education were tested using process- and circuit-specific WM tasks for which clear brain-behaviour relationships had been established in prior functional neuroimaging studies. Patients suffering from acute MDD showed a selective impairment in articulatory rehearsal of verbal information in working memory. By contrast, visuospatial WM was unimpaired in this sample. There were no significant correlations between symptom severity and WM performance. These data indicate a dysfunction of a specific verbal WM system in acutely ill patients with MDD. As the observed functional deficit did not correlate with different symptom scores, further, longitudinal studies are required to clarify whether and how this deficit is related to illness acuity and clinical state of MDD patients

Statement on the Effects of Law Enforcement in School Settings

School-based law enforcement (SBLE) have become increasingly common in U.S. schools over recent decades despite the controversy surrounding their presence and lack of consensus around their associated benefits and harms. Drawing on the history and evidence base regarding SBLE, we advocate for an end to SBLE programs. Grounding our argument in principles of Community Psychology and positive youth development, we outline how the presence and actions of SBLE negatively affect individual students as well as school systems, with particularly harmful outcomes for students with minoritized and marginalized identities. Research on SBLE and school crime does not provide consistent evidence of positive impacts, and many studies find null effects for the relationship between SBLE and school crime or increases in crime and violence in schools. Though funding for SBLE is often prompted by high-profile acts of gun violence in schools, evidence suggests that SBLE neither prevents these incidents, nor lessens the severity when they do occur. Thus, we advocate for removing law enforcement from school settings and redirecting resources into inclusive, evidence-informed responses that are generally safer and more effective than SBLE. We close by outlining the policy landscape governing SBLE programs and ways communities can lobby for change

Wild chimpanzees select tool material based on efficiency and knowledge

This work was funded by the European Research Council (FP7/2007-2013/ERC n°283871) and the Swiss National Science Foundation (grants 310030_143359 to KZ; CR13I1_162720 and P300PA_164678 to TG).Some animals have basic culture, but to date there is not much evidence that cultural traits evolve as part of a cumulative process as seen in humans. This may be due to limits in animal physical cognition, such as an inability to compare the efficiency of a novel behavioural innovation with an already existing tradition. We investigated this possibility with a study on a natural tool innovation in wild chimpanzees: moss-sponging, which recently emerged in some individuals to extract mineral-rich liquids at a natural clay-pit. The behaviour probably arose as a variant of leaf-sponging, a tool technique seen in all studied chimpanzee communities. We found that moss-sponges not only absorbed more liquid but were manufactured and used more rapidly than leaf-sponges, suggesting a functional improvement. To investigate whether chimpanzees understood the advantage of moss- over leaf-sponges, we experimentally offered small amounts of rainwater in an artificial cavity of a portable log, together with both sponge materials, moss and leaves. We found that established moss-spongers (having used both leaves and moss to make sponges) preferred moss to prepare a sponge to access the rainwater, whereas leaf-spongers (never observed using moss) preferred leaves. Survey data finally demonstrated that moss was common in forest areas near clay-pits but nearly absent in other forest areas, suggesting that natural moss-sponging was at least partly constrained by ecology. Together, these results suggest that chimpanzees perceive functional improvements in tool quality, a crucial prerequisite for cumulative culture.PostprintPeer reviewe

Cumulative Lead Exposure and Tooth Loss in Men: The Normative Aging Study

Background: Individuals previously exposed to lead remain at risk because of endogenous release of lead stored in their skeletal compartments. However, it is not known if long-term cumulative lead exposure is a risk factor for tooth loss. Objectives: We examined the association of bone lead concentrations with loss of natural teeth. Methods: We examined 333 men enrolled in the Veterans Affairs Normative Aging Study. We used a validated K-shell X-ray fluorescence (KXRF) method to measure lead concentrations in the tibial midshaft and patella. A dentist recorded the number of teeth remaining, and tooth loss was categorized as 0, 1–8 or ≥ 9 missing teeth. We used proportional odds models to estimate the association of bone lead biomarkers with tooth loss, adjusting for age, smoking, diabetes, and other putative confounders. Results: Participants with ≥ 9 missing teeth had significantly higher bone lead concentrations than those who had not experienced tooth loss. In multivariable-adjusted analyses, men in the highest tertile of tibia lead (> 23 μg/g) and patella lead (> 36 μg/g) had approximately three times the odds of having experienced an elevated degree of tooth loss (≥ 9 vs. 0–8 missing teeth or ≥ 1 vs. 0 missing teeth) as those in the lowest tertile [prevalence odds ratio (OR) = 3.03; 95% confidence interval (CI), 1.60–5.76 and OR = 2.41; 95% CI, 1.30–4.49, respectively]. Associations between bone lead biomarkers and tooth loss were similar in magnitude to the increased odds observed in participants who were current smokers. Conclusion: Long-term cumulative lead exposure is associated with increased odds of tooth loss

Abbreviated dignity therapy for adults with advanced-stage cancer and their family caregivers: Qualitative analysis of a pilot study

Objective Dignity therapy (DT) is designed to address psychological and existential challenges that terminally ill individuals face. DT guides patients in developing a written legacy project in which they record and share important memories and messages with those they will leave behind. DT has been demonstrated to ease existential concerns for adults with advanced-stage cancer; however, lack of institutional resources limits wide implementation of DT in clinical practice. This study explores qualitative outcomes of an abbreviated, less resource-intensive version of DT among participants with advanced-stage cancer and their legacy project recipients. Method Qualitative methods were used to analyze postintervention interviews with 11 participants and their legacy recipients as well as the created legacy projects. Direct content analysis was used to assess feedback from the interviews about benefits, barriers, and recommendations regarding abbreviated DT. The legacy projects were coded for expression of core values. Result Findings suggest that abbreviated DT effectively promotes (1) self-expression, (2) connection with loved ones, (3) sense of purpose, and (4) continuity of self. Participants observed that leading the development of their legacy projects promoted independent reflection, autonomy, and opportunities for family interaction when reviewing and discussing the projects. Consistent with traditional DT, participants expressed “family” as the most common core value in their legacy projects. Expression of “autonomy” was also a notable finding. Significance of results Abbreviated DT reduces resource barriers to conducting traditional DT while promoting similar benefits for participants and recipients, making it a promising adaptation warranting further research. The importance that patients place on family and autonomy should be honored as much as possible by those caring for adults with advanced-stage cancer

Remote Infrared Imaging of the Space Shuttle During Hypersonic Flight: HYTHIRM Mission Operations and Coordination

The Hypersonic Thermodynamic Infrared Measurements (HYTHIRM) project has been responsible for obtaining spatially resolved, scientifically calibrated in-flight thermal imagery of the Space Shuttle Orbiter during reentry. Starting with STS-119 in March of 2009 and continuing through to the majority of final flights of the Space Shuttle, the HYTHIRM team has to date deployed during seven Shuttle missions with a mix of airborne and ground based imaging platforms. Each deployment of the HYTHIRM team has resulted in obtaining imagery suitable for processing and comparison with computational models and wind tunnel data at Mach numbers ranging from over 18 to under Mach 5. This paper will discuss the detailed mission planning and coordination with the NASA Johnson Space Center Mission Control Center that the HYTHIRM team undergoes to prepare for and execute each mission

Biofluorescence in Catsharks (Scyliorhinidae): Fundamental Description and Relevance for Elasmobranch Visual Ecology

Biofluorescence has recently been found to be widespread in marine fishes, including sharks. Catsharks, such as the Swell Shark (Cephaloscyllium ventriosum) from the eastern Pacific and the Chain Catshark (Scyliorhinus retifer) from the western Atlantic, are known to exhibit bright green fluorescence. We examined the spectral sensitivity and visual characteristics of these reclusive sharks, while also considering the fluorescent properties of their skin. Spectral absorbance of the photoreceptor cells in these sharks revealed the presence of a single visual pigment in each species. Cephaloscyllium ventriosum exhibited a maximum absorbance of 484 ± 3 nm and an absorbance range at half maximum (λ1/2max) of 440–540 nm, whereas for S. retifer maximum absorbance was 488 ± 3 nm with the same absorbance range. Using the photoreceptor properties derived here, a “shark eye” camera was designed and developed that yielded contrast information on areas where fluorescence is anatomically distributed on the shark, as seen from other sharks’ eyes of these two species. Phylogenetic investigations indicate that biofluorescence has evolved at least three times in cartilaginous fishes. The repeated evolution of biofluorescence in elasmobranchs, coupled with a visual adaptation to detect it; and evidence that biofluorescence creates greater luminosity contrast with the surrounding background, highlights the potential importance of biofluorescence in elasmobranch behavior and biology
