A Review of Teachers\u27 Perceptions and Training Regarding School Bullying

This review will explore what is currently known regarding teachers’ perceptions, knowledge, and training regarding school bullying. Bullying is a serious issue for children and adolescents in schools. Research has consistently reported that bullying may cause lasting psychological and emotional problems (Mishna, Scarcello, Pepler, & Wiener, 2005). Teachers spend a significant amount of time with students at school and may be at the front-line of prevention and intervention strategies (Lund, Blake, Ewing, & Banks, 2012). One of the main determining factors in effectiveness of an anti-bullying program is the quality of staff training (Lund, et al., 2012). Research suggests that teachers are in great need of and desire more training on the topic of school bullying, its prevention, and effective intervention strategies. This review will highlight specific research areas where more information is needed about teachers’ perceptions, knowledge, and training regarding bullying in schools and how school districts can best use this information to target training programs for teachers

Pilot Sensitivity to Simulator Flight Dynamics Model Formulation for Stall Training

A piloted simulation study was performed in the Cockpit Motion Facility at the National Aeronautics and Space Administration Langley Research Center. The research was motivated by the desire to reduce the commercial transport airplane fatal accident rate due to in-flight loss of control. The purpose of this study, which focused on a generic T-tail transport airplane, was to assess pilot sensitivity to flight dynamics model formulation used during a simulator stall recognition and recovery training/demonstration profile. To accomplish this, the flight dynamics model was designed with many configuration options. The model options were based on recently acquired static and dynamic stability and control data from sources that included wind tunnel, water tunnel, and computational fluid dynamics. The results, which are specific to a transport airplane stall recognition and recovery guided demonstration scenario, showed the two most important aerodynamic effects (other than stick pusher) to model were stall roll- off and the longitudinal static stability characteristic associated with the pitch break

Eating Competent Parents of 4th Grade Youth from a Predominantly Non-Hispanic White Sample Demonstrate More Healthful Eating Behaviors than Non-Eating Competent Parents

The purpose of this study was to determine if the associations between eating competence (EC) and eating behaviors that were found in a USA sample of predominantly Hispanic parents of 4th grade youth could be replicated in a USA sample of predominantly non-Hispanic white parents of 4th graders. Baseline responses from parents (n = 424; 94% white) of youth participating in a year-long educational intervention were collected using an online survey. Validated measures included the Satter Eating Competence Inventory (ecSI 2.0TM), in-home fruit/vegetable (FV) availability, healthful eating behavior modeling, and FV self-efficacy/outcome expectancies (SE/OE). Data were analyzed with general linear modeling and cluster analyses. The findings replicated those from the primarily Hispanic sample. Of the 408 completing all ecSI 2.0TM items, 86% were female, 65% had a 4-year degree or higher, and 53% were EC (ecSI 2.0TM score ≥ 32). Compared with non-EC parents, EC modeled more healthful eating, higher FV SE/OE, and more in-home FV availability. Behaviors clustered into those striving toward more healthful practices (strivers; n = 151) and those achieving them (thrivers; n = 255). Striver ecSI 2.0TM scores were lower than those of thrivers (29.6 ± 7.8 vs. 33.7 ± 7.6; p \u3c 0.001). More EC parents demonstrated eating behaviors associated with childhood obesity prevention than non-EC parents, encouraging education that fosters parent EC, especially in tandem with youth nutrition education

The Effects of Regular Yoga Practice on Psychophysiological Measures in College Students

PURPOSE: The purpose of this study was to test the hypothesis that 12 weeks of a regular yoga practice (150 minutes/week) would improve measures of cardiovascular and psychological health in college students. METHODS: Twenty-two college students (211.2 yrs; 21 female) participated in this study. Height, weight, waist/hip circumference, resting blood pressure and heart rate, fasting blood glucose and cholesterol, and psychological health (STAI form Y-1 and Y-2) were assessed prior to the end of the third week of the semester (PRE). Subjects participated in their Yoga I class throughout Fall semester. After the 12th week of class, participants reported to the laboratory for follow up testing (POST). RESULTS: A significant improvement in trait anxiety (Y-2), assessing participants’ disposition to develop anxiety as a part of their personality, was observed after 12 weeks of a regular yoga program (PRE: 392 vs POST: 341.8; p=0.002). There was no change in state anxiety (Y-1), assessing participants’ levels of anxiety “in the moment” (PRE: 341.7 vs POST: 331.9; p=0.96). There was also no change in weight, waist/hip circumference, resting heart rate, resting blood pressure, fasting blood glucose, or cholesterol measurements from PRE to POST testing. CONCLUSION: 12 weeks of regular attendance to a beginner yoga program improved measures of (personality) trait-anxiety in college students

Chemical Cartography of the Sagittarius Stream with Gaia

The stellar stream connected to the Sagittarius (Sgr) dwarf galaxy is the most massive tidal stream that has been mapped in the Galaxy, and is the dominant contributor to the outer stellar halo of the Milky Way. We present metallicity maps of the Sgr stream, using 34,240 red giant branch stars with inferred metallicities from Gaia BP/RP spectra. This sample is larger than previous samples of Sgr stream members with chemical abundances by an order of magnitude. We measure metallicity gradients with respect to Sgr stream coordinates $(\Lambda, B)$, and highlight the gradient in metallicity with respect to stream latitude coordinate $B$, which has not been observed before. We find $\nabla \mathrm{[M/H]} = -2.48 \pm 0.08 \times 10^{-2}$ dex/deg above the stream track ($B>B_0$ where $B_0=1.5$ deg is the latitude of the Sgr remnant) and $\nabla \mathrm{[M/H]} =- 2.02 \pm 0.08 \times 10^{-2}$ dex/deg below the stream track ($B<B_0$). By painting metallicity gradients onto a tailored N-body simulation of the Sgr stream, we find that the observed metallicities in the stream are consistent with an initial radial metallicity gradient in the Sgr dwarf galaxy of $\sim -0.1$ to $-0.2$ dex/kpc, well within the range of observed metallicity gradients in Local Group dwarf galaxies. Our results provide novel observational constraints for the internal structure of the dwarf galaxy progenitor of the Sgr stream. Leveraging new large datasets in conjunction with tailored simulations, we can connect the present day properties of disrupted dwarfs in the Milky Way to their initial conditions.Comment: 20 pages, 12 figures.

Thymic stromal lymphopoietin blocks early stages of breast carcinogenesis

Advances in the field of cancer immunology, including studies on tumor-infiltrating CD8(+) cytotoxic T lymphocytes (CTLs), have led to new immunotherapeutics with proven efficacy against late-stage cancers. However, the antitumor potential of the immune system in targeting early-stage cancers remains uncertain. Here, we demonstrated that both genetic and chemical induction of thymic stromal lymphopoietin (TSLP) at a distant site leads to robust antitumor immunity against spontaneous breast carcinogenesis in mice. Breast tumors exposed to high circulating levels of TSLP were arrested at an early adenoma-like stage and were prevented from advancing to late carcinoma and metastasis. Additionally, CD4(+) Th2 cells mediated the antitumor effects of TSLP, challenging the notion that Th2 cells only promote cancer. We also discovered that TSLP is expressed by the breast tumor cells themselves and acts to block breast cancer promotion. Moreover, TSLP-induced immunity also blocked early stages of pancreatic cancer development. Together, our findings demonstrate that TSLP potently induces immunity directed against early stages of breast cancer development without causing inflammation in the normal breast tissue. Moreover, our results highlight a previously unappreciated function of the immune system in controlling the early development of cancer and establish a fundamental role for TSLP and Th2 cells in tumor immunity against early-stage cancers
