Portrayals of Bullying in Childrenâs Picture Books and Implications for Bibliotherapy
Bullying, a serious issue in todayâs schools, negatively impacts children. This article summarizes research and emphasizes the need for effective tools, such as bibliotherapy, to deter bullying. To assist professionals in selecting books for bibliotherapy, 38 bully-themed childrenâs K-3 picture books ranked 1- 4 by The Horn Book Guide (HBG) from January 1, 2004 through January 1, 2010 were analyzed. Comparisons were made between the selected booksâ portrayals of bullying and aspects of bullying, and bully prevention described in research literature. Information was summarized, including the following details: (a) gender of bully and victim, (b) type of bullying, (c) location of bullying, (d) responses of bystanders and adults, and (e) resolution of bullying problems. Considering this descriptive information, professionals are advised to more selectively recommend books to fit the unique needs of students and encourage desired bullying resolution strategies
Serum Iron Level is Associated with Time to Antibiotics in Cystic Fibrosis
Background:
Serum levels of hepcidinâ25, a peptide hormone that reduces blood iron content, are elevated when patients with cystic fibrosis (CF) develop pulmonary exacerbation (PEx). Because hepcidinâ25 is unavailable as a clinical laboratory test, we questioned whether a oneâtime serum iron level was associated with the subsequent number of days until PEx, as defined by the need to receive systemic antibiotics (ABX) for health deterioration. Methods:
Clinical, biochemical, and microbiological parameters were simultaneously checked in 54 adults with CF. Charts were reviewed to determine when they first experienced a PEx after these parameters were assessed. Time to ABX was compared in subgroups with and without specific attributes. Multivariate linear regression was used to identify parameters that significantly explained variation in time to ABX. Results:
In univariate analyses, time to ABX was significantly shorter in subjects with Aspergillusâpositive sputum cultures and CFârelated diabetes. Multivariate linear regression models demonstrated that shorter time to ABX was associated with younger age, lower serum iron level, and Aspergillus sputum culture positivity. Conclusions:
Serum iron, age, and Aspergillus sputum culture positivity are factors associated with shorter time to subsequent PEx in CF adults
Amygdala and Nucleus Accumbens Activation to Emotional Facial Expressions in Children and Adolescents at Risk for Major Depression
Objective. Offspring of parents with major depressive disorder (MDD) face three-fold higher risk for MDD than offspring without a family history. Although MDD is a major cause of morbidity and mortality, neural correlates of risk for MDD remain poorly understood. This study compares amygdala and nucleus accumbens activation in children and adolescents at high and low risk for MDD under varying attentional and emotional conditions. Methods. Thirty-nine juveniles, 17 offspring of parents with MDD (high-risk group) and 22 offspring of parents without histories of MDD, anxiety or psychotic disorders (low-risk group) completed a functional magnetic resonance imaging study. During imaging, subjects viewed faces that varied in intensity of emotional expressions across blocks of trials; while attention was unconstrained (passive viewing), and constrained (rate nose width on face; rate subjective fear while viewing face). Results. When attention was unconstrained, high-risk, relative to low-risk, subjects showed greater amygdala and nucleus accumbens (NAcc) activation to fearful faces, and lower NAcc activation to happy faces (p values \u3c .05, small volume corrected for the amygdala and NAcc). No group differences emerged in amygdala or NAcc activation during constrained attention. Exploratory analysis showed that constraining attention was associated with greater medial prefrontal cortex activation in the high-risk than low-risk group. Conclusions. Amygdala and NAcc responses to affective stimuli may reflect vulnerability for MDD. Constraining attention may normalize emotion-related neural function, possibly via engagement of the medial prefrontal cortex; face-viewing with unconstrained attention may engage aberrant processes associated with risk for MDD
Contact heat evoked potentials using simultaneous EEG and fMRI and their correlation with evoked pain
BACKGROUND: The Contact Heat Evoked Potential Stimulator (CHEPS) utilises rapidly delivered heat pulses with adjustable peak temperatures to stimulate the differential warm/heat thresholds of receptors expressed by Adelta and C fibres. The resulting evoked potentials can be recorded and measured, providing a useful clinical tool for the study of thermal and nociceptive pathways. Concurrent recording of contact heat evoked potentials using electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) has not previously been reported with CHEPS. Developing simultaneous EEG and fMRI with CHEPS is highly desirable, as it provides an opportunity to exploit the high temporal resolution of EEG and the high spatial resolution of fMRI to study the reaction of the human brain to thermal and nociceptive stimuli. METHODS: In this study we have recorded evoked potentials stimulated by 51° C contact heat pulses from CHEPS using EEG, under normal conditions (baseline), and during continuous and simultaneous acquisition of fMRI images in ten healthy volunteers, during two sessions. The pain evoked by CHEPS was recorded on a Visual Analogue Scale (VAS). RESULTS: Analysis of EEG data revealed that the latencies and amplitudes of evoked potentials recorded during continuous fMRI did not differ significantly from baseline recordings. fMRI results were consistent with previous thermal pain studies, and showed Blood Oxygen Level Dependent (BOLD) changes in the insula, post-central gyrus, supplementary motor area (SMA), middle cingulate cortex and pre-central gyrus. There was a significant positive correlation between the evoked potential amplitude (EEG) and the psychophysical perception of pain on the VAS. CONCLUSION: The results of this study demonstrate the feasibility of recording contact heat evoked potentials with EEG during continuous and simultaneous fMRI. The combined use of the two methods can lead to identification of distinct patterns of brain activity indicative of pain and pro-nociceptive sensitisation in healthy subjects and chronic pain patients. Further studies are required for the technique to progress as a useful tool in clinical trials of novel analgesics
Voices from the field: How did you come to engage in students-as-partners work?
The language of students as partners was cemented into higher education (HE) practice and scholarship 10 years ago. While it had been circulating in higher education policy, practices, and publications before that, two key 2014 publications on engaging students as partners, or SaP, inspired a myriad of practices and publications brought together by the relational, values-based ethos of partnership (Cook-Sather et al., 2014; Healey et al., 2014). A seductively simple ideaâ that students can collaborate with staff as partners on matters of teaching and learningâlanded at the right time. The higher education sector was increasingly fixated on student involvement and engagement, particularly on how university changes students (KlemenÄiÄ, 2024). SaP offered a related but direction-shifting proposition: what if students could shape higher education
