Cyberbullying, Bullying, and Victimization among Adolescents: Rates of Occurrence, Internet Use and Relationship to Parenting Styles
Cyberbullying has evolved from the increasing use of technology, specifically electronic communication and social networking. Cyberbullying is defined as a means of bullying in which peers use electronic devices to taunt, insult, threaten, harass, and/or intimidate a peer (Raskauskas & Stoltz, 2007, p. 565). This could occur through a number of different electronic formats or devices such as email, social networking sites, cell phones, etc. In this study, participants included a total of 77 students attending a Southeastern Tennessee City Middle and High School. This included 23 seventh-grade students, 31 eighth-grade students and 23 ninth grade students. Participants were administered an online questionnaire that included a Demographic Information Sheet (Appendix E), the Bullying/Cyberbullying Scale (Smith et al., 2008), and The Inventory of Parental Influence (Campbell & Verna, 2007).
The prevalence of bullying, cyberbullying and victimization in this sample was high. Over half of the students (53.2%, n = 41) had taken part in bullying in their lifetime. About a third of the students (31.2%, n = 24) reported taking part in cyberbullying. Overall, 49.4% (n = 38) of the students had been bullied in their lifetime, while 28.6% were victims of cyberbullying (n = 22). Relative to males, significantly more females were both perpetrators of cyberbullying and bullying, and significantly more females were both victims of cyberbullying and bullying. I ran four discriminant function analyses to determine whether parental influences (help, support, and pressure), would predict bullying, cyberbullying and victimization by bullying and cyberbullying. All results were non-significant.
These findings enhance our understanding of the rates of occurrence of bullying, cyberbullying and victimization among adolescents. Internet use among adolescents should be monitored for potential trends. Implications for future research and school-based interventions are discussed
Properties and Nutrient Status of Degraded Soils in Luzon, Philippines
A prerequisite to soil management, particularly in degraded soils, is a good knowledge of the characteristics and fertility status of degraded soil, which is fundamental to planning suitable soil management strategies for crop production purposes. The aim of this study was to determine the physico-chemical and mineralogical properties and fertility constraints of degraded soils in Luzon, Philippines. Ten surface soil samples were collected from 10 degraded soils representing the dominant soil series in Luzon Island. These soils were analyzed for physical, chemical and mineralogical properties. Results revealed that all soils have high clay content (except Bantay soil), which impedes cultivation. All soils were acidic, have a very low organic matter (OM), total N, available P, and low to moderately low exchangeable cations. X-ray diffraction reveals the dominance of halloysite/kaolinite, quartz and hematite in all soils. Results further revealed that all soils have fertility constraints, particularly acidic soils, low OM, low total N, and low available P. All soils contain sufficient exchangeable Ca, but low to high exchangeable K, particularly in soils of Annam, Bolinao, Bantay and Cervantes. Together, these results suggest that all soils possess physical and chemical constraints to crop production and the occurrence of constraints varies with soil type, location in the landscape, slope and parent material. The recognition of these fertility constraints is essential for the long-term planning of soil management strategies essential to sustainable utilization of these degraded soils
Differences in Prenatal Tobacco Exposure Patterns among 13 Race/Ethnic Groups in California.
Prenatal tobacco exposure is a significant, preventable cause of childhood morbidity, yet little is known about exposure risks for many race/ethnic subpopulations. We studied active smoking and environmental tobacco smoke (ETS) exposure in a population-based cohort of 13 racially/ethnically diverse pregnant women: white, African American, Hispanic, Native American, including nine Asian/Pacific Islander subgroups: Chinese, Japanese, Korean, Filipino, Cambodian, Vietnamese, Laotian, Samoan, and Asian Indians (N = 3329). Using the major nicotine metabolite, cotinine, as an objective biomarker, we analyzed mid-pregnancy serum from prenatal screening banked in 1999⁻2002 from Southern California in an effort to understand differences in tobacco exposure patterns by race/ethnicity, as well as provide a baseline for future work to assess secular changes and longer-term health outcomes. Prevalence of active smoking (based on age- and race-specific cotinine cutpoints) was highest among African American, Samoan, Native Americans and whites (6.8⁻14.1%); and lowest among Filipinos, Chinese, Vietnamese and Asian Indians (0.3⁻1.0%). ETS exposure among non-smokers was highest among African Americans and Samoans, followed by Cambodians, Native Americans, Vietnamese and Koreans, and lowest among Filipinos, Japanese, whites, and Chinese. At least 75% of women had detectable cotinine. While for most groups, levels of active smoking corresponded with levels of ETS, divergent patterns were also found. For example, smoking prevalence among white women was among the highest, but the group's ETS exposure was low among non-smokers; while Vietnamese women were unlikely to be active smokers, they experienced relatively high ETS exposure. Knowledge of race/ethnic differences may be useful in assessing disparities in health outcomes and creating successful tobacco interventions
Protective Places: the Relationship between Neighborhood Quality and Preterm Births to Black Women in Oakland, California (2007–2011)
Black women have the highest incidence of preterm birth (PTB). Upstream factors, including neighborhood context, may be key drivers of this increased risk. This study assessed the relationship between neighborhood quality, defined by the Healthy Places Index, and PTB among Black women who lived in Oakland, California, and gave birth between 2007 and 2011 (N = 5418 women, N = 107 census tracts). We found that, compared with those living in lower quality neighborhoods, women living in higher quality neighborhoods had 20–38% lower risk of PTB, independent of confounders. Findings have implications for place-based research and interventions to address racial inequities in PTB
Evaluation of Emergency Medicine Community Educational Program
Out-of-hospital emergencies occur frequently, and laypersons are often the first to respond to these events. As an outreach to our local communities, we developed “Basic Emergency Interventions Everyone Should Know,” a three-hour program addressing cardiopulmonary resuscitation and automated external defibrillator use, heart attack and stroke recognition and intervention, choking and bleeding interventions and infant and child safety. Each session lasted 45 minutes and was facilitated by volunteers from the emergency department staff. A self-administered 13-item questionnaire was completed by each participant before and after the program. A total of 183 participants completed the training and questionnaires. Average score pre-training was nine while the average score post-training was 12 out of a possible 13 (P< .0001). At the conclusion of the program 97% of participants felt the training was very valuable and 100% would recommend the program to other members of their community

The Association Between Pre-pregnancy BMI and Preterm Delivery in a Diverse Southern California Population of Working Women
Whereas preterm birth has consistently been associated with low maternal pre-pregnancy weight, the relationship with high pre-pregnancy weight has been inconsistent. We quantified the pre-pregnancy BMI—preterm delivery (PTD) relationship using traditional BMI categories (underweight, normal weight, overweight and obese) as well as continuous BMI. Eligible women participated in California’s statewide prenatal screening program, worked during pregnancy, and delivered a live singleton birth in Southern California in 2002–2003. The final analytic sample included 354 cases delivering at <37 weeks, as identified by clinical estimate of gestational age from screening records, and 710 term normal-birthweight controls. Multivariable logistic regression models using categorical BMI levels and continuous BMI were compared. In categorical analyses, PTD was significantly associated with pre-pregnancy underweight only. Nonparametric local regression revealed a V-shaped relationship between continuous BMI and PTD, with minimum risk at the high end of normal, around 24 kg/m2. The odds ratio (OR) for PTD associated with low BMI within the normal range (19 kg/m2) was 2.84 (95%CI = 1.61–5.01); ORs for higher BMI in the overweight (29 kg/m2) and obese (34 kg/m2) ranges were 1.42 (95%CI = 1.10–1.84) and 2.01 (95% CI = 1.20–3.39) respectively, relative to 24 kg/m2). BMI categories obscured the preterm delivery risk associated with low-normal, overweight, and obese BMI. We found that higher BMI up to around 24 kg/m2 is increasingly protective of preterm delivery, beyond which a higher body mass index becomes detrimental. Current NHLBI/WHO BMI categories may be inadequate for identifying women at higher risk for PTD
