    Despite the critical role teachers play in the management and reduction of bullying in schools (Craig, Henderson, & Murphy, 2000; Frey, Jones, Hirschstein, & Edstrom, 2011; Nicolaides, Toda, & Smith, 2002), minimal research has been conducted examining teachers’ responses to these negative behaviors (Bauman & Hurley, 2005; Marshall, Varjas, Meyers, Graybill, & Skoczylas, 2009; Sairanen & Pfeffer, 2011; Yoon & Kerber, 2003). Moreover, a critical topic lacking in the literature is the identification of potential barriers (e.g., difficulty identifying bullying, lack of time to address these behaviors) inhibiting teachers from successful intervention. The purpose of this exploratory study was to assess teachers’ perceived barriers to effective bullying intervention, as well as to examine potential relationships between how teachers reported responding to bullying and perceived barriers to successful intervention. Individual in-depth qualitative interviews with 30 fourth through eighth grade teachers were used to determine teachers’ responses and perceived barriers to bullying interventions. Inductive and deductive approaches to data analysis (LeCompte & Schensul, 1999; Nastasi & Schensul, 2005; Varjas, Nastasi, Moore, & Jayasena, 2005) were used to explore teachers’ self-reported barriers. Teachers described the presence of numerous barriers that challenged their ability to consistently and effectively respond to bullying. Qualitative results indicated that these barriers occurred on multiple levels and included the following four major themes: student-, teacher-, school- and sociocultural-based barriers. Further, quantitative analyses were used to investigate potential relationships between teachers’ self-reported responses to bullying and perceived barriers. No systematic relationships were evident. That is, teachers reported responding to bullying similarly regardless of their perceived barriers to effective intervention. Implications for improving and informing anti-bullying efforts aimed at eliminating these barriers and increasing the likelihood of teacher intervention are discussed. Future research ideas also are suggested

    Hereditary pancreatitis is characterized by episodes of pancreatic inflammation accompanied by unrelenting abdominal pain, usually beginning in childhood. Therefore, this emerging population of individuals is affected with a chronic pain condition affecting global quality of life. A multidisciplinary approach, including psychosocial and behavioral factors, is necessary to elicit responses to and treat chronic pain. Improving overall quality of life is an important outcome of interventions for chronic conditions. Health-related quality of life reflects an individual's physical and mental well-being. This study documents the pain levels and quality of life of individuals with both hereditary and sporadic pancreatitis. Data from 73 individuals with hereditary pancreatitis and 271 individuals with sporadic pancreatitis who participated in the Hereditary Pancreatitis Study and the North American Pancreatitis Study 2 were examined for this study. The questionnaires addressed each subject's report of quality of life, severity and duration of pain, alcohol use, tobacco use, and diagnosis of diabetes. Patient responses were analyzed using a battery of comparative analyses. The SF-122 health survey was analyzed using an algorithm for standardizing and weighting the physical and mental health scores. Pain and quality of life measures were compared to each other, as well as to several commonly measured environmental influences on health using correlation analysis, regression analysis, and the Mann-Whitney U test. As hypothesized, individuals with familial pancreatitis reported worse pain and poorer overall quality of life than individuals with sporadic pancreatitis. Factors influencing the measure of pain include the duration, severity, frequency, and character. Other findings include correlations between (a) physical quality of life and gender, smoking, and alcohol, (b) pain and age, and (c) pain frequency and tobacco and alcohol use. This study provides information that can potentially assist health care professionals who work with individuals with pancreatitis and chronic pain, and who are assessing the necessity of psychosocial intervention or support services

    What Types of Courses Best Prepare Students?

    I wanted to do a study on how people learn best because I think it’s important for instruction to be effective for productive learning. A lot of professors or future teachers need to know what style of class will work best for their learners. I wanted to know if college students learn best in lecture style, studio style or lab style classes and I thought college students would learn best in studio. In my results, I found that most students liked lecture style classes but learned best from lab style classes. I hope to take the knowledge I gained from this research into my classroom in the future

    What do Cats do All Day?

    When we look at zoo animals, we only see them for a couple of minutes at most. We do not see how active they really are, nor do we get a good representation of their behavior (Szokalski et al 2012; Allen et al. 2015). Cats are usually seen as lazy, sleepy animals. However, what do zoo cats really do during the day? Following four separate visits of 70 minutes each, the results showed a correlation between social behavior/movement based on size of the animal. There is a clear difference in the level of activity and observable behaviors among these species of big cat. The data suggest that smaller cats, like the Bobcat may be better at showing the public a wider range of behaviors

    Efficacy of ginger (Zingiber officinale) in ameliorating chemotherapy-induced nausea and vomiting and chemotherapy-related outcomes: a systematic review update and meta-analysis

    Get PDF
    Background: Ginger has been proposed as an adjuvant treatment for chemotherapy-induced nausea and vomiting. Objective: The aim of this systematic review with meta-analyses is to evaluate, in adult cancer patients receiving chemotherapy, the effects of ginger supplementation dose and duration on the incidence, duration, and severity of chemotherapy-induced nausea and vomiting and outcomes related to chemotherapy-induced nausea and vomiting (eg, quality of life and fatigue), compared with placebo or standard antiemetic medication. Method: Five electronic databases were searched from database inception to April 2018. The quality of evidence was appraised with the Cochrane Risk of Bias tool and Grading of Recommendations, Assessment, Development, and Evaluation level. Data were pooled using Revman software. Results: Eighteen articles were analyzed. The likelihood of acute vomiting was reduced by 60% with ginger supplementation ≤1 g/day for duration >3 days, compared with control groups (odds ratio 0.4, 95% CI 0.17 to 0.81; P=0.01; n=3 studies; n=3 interventions; n=301 participants; I2=20%; Grading of Recommendations, Assessment, Development, and Evaluation level: Moderate). The likelihood of fatigue was reduced by 80% with ginger supplementation of any dose for duration 2=0%; Grading of Recommendations, Assessment, Development, and Evaluation level: Low). No statistically significant association was found between ginger and likelihood of overall or delayed vomiting, likelihood or severity of nausea, or other outcomes related to chemotherapy-induced nausea and vomiting. Conclusions: Ginger supplementation might benefit chemotherapy-induced vomiting as well as fatigue. Due to clinical heterogeneity, this systematic review update found no association between ginger and chemotherapy-induced nausea and other chemotherapy-induced nausea and vomiting-related outcomes. The results of this systematic review and meta-analysis provide a rationale for further research with stronger study designs, adequate sample sizes, standardized ginger products, and validated outcome measures to confirm efficacy of ginger supplementation and optimal dosing regimens.</p

    Prophylactic and Therapeutic Breast Conservation in BRCA1/2 Mutation Carriers

    Breast-conserving therapy (BCT) for sporadic breast cancer has been widely accepted by surgeons and patients alike. While BCT is associated with a higher risk of ipsilateral breast tumor recurrence (IBTR), it has not been shown to decrease overall survival (OS) in comparison with mastectomy. Many women with a BRCA1/2 mutation opt for mastectomy instead of breast-conserving measures at the time of a breast cancer diagnosis. In some cases, this is due to fear of aggressive disease, but to date, there have been no studies offering strong evidence that breast conservation should not be offered to these women. BRCA1/2-associated breast cancer has not been found to be more aggressive or resistant to treatment than comparable sporadic tumors, and no study has shown an actual survival advantage for mastectomy in appropriately treated affected mutation carriers. This paper reviews the available literature for breast conservation and surgical decision making in BRCA1/2 mutation carriers

    Optical detection of the Pictor A jet and tidal tail : evidence against an IC/CMB jet

    Get PDF
    Date of Acceptance: 12/06/2015New images of the FR II radio galaxy Pictor A from the Hubble Space Telescope reveal a previously undiscovered tidal tail, as well as a number of jet knots coinciding with a known X-ray and radio jet. The tidal tail is approximately 5″ wide (3 kpc projected), starting 18″ (12 kpc) from the center of Pictor A, and extends more than 90″ (60 kpc). The knots are part of a jet observed to be about 4′ (160 kpc) long, extending to a bright hotspot. These images are the first optical detections of this jet, and by extracting knot flux densities through three filters, we set constraints on emission models. While the radio and optical flux densities are usually explained by synchrotron emission, there are several emission mechanisms that might be used to explain the X-ray flux densities. Our data rule out Doppler-boosted inverse Compton scattering as a source of the high-energy emission. Instead, we find that the observed emission can be well described by synchrotron emission from electrons with a low-energy index (p ∼ 2) that dominates the radio band, while a high-energy index (p ∼ 3) is needed for the X-ray band and the transition occurs in the optical/infrared band. This model is consistent with a continuous electron injection scenario.Peer reviewedFinal Accepted Versio

    Wet Corn Stover Storage: Correlating Fiber Reactivity With Storage Acids Over a Wide Moisture Range

    Get PDF
    Wet storage is synonymous with ensilage, a simple biotechnology that has been used to preserve forage for livestock feed for millennia. In this natural process, organic acids are produced by anaerobic microbial degradation of a small fraction of the biomass, and these acids reduce the pH to levels that minimize further microbial activity and can preserve the biomass for years as long as anaerobic conditions are maintained. These organic acids also result in mild pretreatment with potential to enhance downstream conversion processes, making this an effective storage strategy. However, the degree and significance of this natural pretreatment capability of ensiled storage on downstream processes has not previously been quantified across a range of storage conditions. In this study, the degree of pretreatment was investigated by measuring the reactivity of corn stover fiber to cellulolytic enzymes. Although the results indicated significant improvement in hydrolytic outcomes after wet storage, by a factor of up to 2.4, saccharification of cellulose to sugar monomers was still limited. The results also show that dominance of lactic acid in the ensilage process is key to wet storage (pretreatment) effectiveness as in the livestock feed industry. Lactic acid pKa value is lower than the pKa of other silage acids and lower than typical silage pH. This gives lactic acid the advantage of being in the more dissociated form, with more protons available to facilitate pretreatment hydrolysis. However, unlike the livestock feed industry, where quality feedstock is attainable within very narrow storage moisture range, for biofuel purposes, a wider range of 35–65% is appropriate in achieving a similar quality outcome. This is true both for the immediate fiber response to enzymes and with subsequent pretreatment. This wider moisture range implies more flexibility in harvest schedule without sacrificing feedstock quality, thus alleviating concerns over feedstock quality that biomass suppliers or biorefineries may have

    Multiwavelength Monitoring of the BL Lacertae Object PKS 2155-304 in May 1994. II. The IUE Campaign

    PKS 2155-304, the brightest BL Lac object in the ultraviolet sky, was monitored with the IUE satellite at ~1 hour time-resolution for ten nearly uninterrupted days in May 1994. The campaign, which was coordinated with EUVE, ROSAT, and ASCA monitoring, along with optical and radio observations from the ground, yielded the largest set of spectra and the richest short time scale variability information ever gathered for a blazar at UV wavelengths. The source flared dramatically during the first day, with an increase by a factor ~2.2 in an hour and a half. In subsequent days, the flux maintained a nearly constant level for ~5 days, then flared with ~35% amplitude for two days. The same variability was seen in both short- and long-wavelength IUE light curves, with zero formal lag (~<2 hr), except during the rapid initial flare, when the variations were not resolved. Spectral index variations were small and not clearly correlated with flux. The flux variability observed in the present monitoring is so rapid that for the first time, based on the UV emission alone, the traditional Delta L/Delta t limit indicating relativistic beaming is exceeded. The most rapid variations, under the likely assumption of synchrotron radiation, lead to a lower limit of 1 G on the magnetic field strength in the UV emitting region. These results are compared with earlier intensive monitoring of PKS 2155-304 with IUE in November 1991, when the UV flux variations had completely different characteristics.Comment: 45 pages, Latex, 11 PostScript figures, to appear in The Astrophysical Journa
