A new approach to equipment testing

Considerable controversy has arisen during the recent discussions over a new version of the RTCA DO160C/ED 14C Section 22 document at the European Committee for Aviation Electronics. Section 22 is concerned with lightning waveform tests to equipment. Investigations of some of these controversies with circuit analysis and measurements indicate the impedance characteristics required of the transient generators and the possibility of testing to a voltage limit even for current waveforms

Methods: A psychometric evaluation study of the London Measure of Unplanned Pregnancy (LMUP), a six-item, self-completion paper measure was conducted with 346 women aged 15–45 who presented to San Francisco General Hospital for termination of pregnancy or antenatal care. Analyses of the two language versions were carried out separately. Reliability (internal consistency) was assessed using Cronbach’s alpha and item-total correlations. Test-retest reliability (stability) was assessed using weighted Kappa. Construct validity was assessed using principal components analysis and hypothesis testing. Results: Psychometric testing demonstrated that the LMUP was reliable and valid in both U.S. English (alpha = 0.78, all item-total correlations .0.20, weighted Kappa = 0.72, unidimensionality confirmed, hypotheses met) and Spanish translation (alpha = 0.84, all item-total correlations .0.20, weighted Kappa = 0.77, unidimensionality confirmed, hypotheses met). Conclusion: The LMUP was reliable and valid in U.S. English and Spanish translation and therefore may now be used with U.S. women.The study was funded by an anonymous donation

The classroom check-up : modularizing effective classroom management interventions to support teacher implementation

Classroom management is a hot topic in schools today. The challenges associated with student problem behavior and classroom management often create problems for both teachers and schools. There is substantial research on behavior and classroom management indicating that teacher behavior can significantly influence student behavior and that intervening at the classroom level is an effective way to improve students’ behavior problems. Therefore, it would be beneficial to identify ways to support classroom teachers in using effective classroom management strategies. The purpose of the current study was to develop and evaluate a set of modules on the best practices in effective classroom management. The project consisted of two phases: Phase I) CCU modules were developed based on literature reviews and evidence-based interventions and Phase II) The CCU modules were piloted using the CCU Consultation Model with five elementary school classroom teachers using a multiple baseline design. In Phase II feedback was obtained from nine experts in the field of coaching and consultation and the CCU modules were revised based on the suggested feedback. The results of this study are promising that the CCU consultation process combined with the initial modules resulted in positive teacher and student behavior change. Teachers, school psychologists, school administrators and students would benefit from continued research on the CCU in conjunction with the developed modules using natural implementers in schools

Non-contraceptive applications of the levonorgestrel intrauterine system

This article describes the evidence for use of intrauterine progestin for common gynecologic conditions beyond its important role in contraception. The pharmacology of and selection criteria for use of the levonorgestrel intrauterine device is discussed, and the evidence for use of intrauterine progestin delivery for menorrhagia, endometriosis management, uterine fibroids, adenomyosis and endometrial hyperplasia is reviewed

The experience and aftermath of chronic bullying on individuals' socio-emotional development

Bullying behaviour is fast becoming a common feature in schools around the world. It is a practice that provokes concern, as it infringes upon the child’s right to human dignity, privacy, freedom and security. The physical, emotional and educational consequences of bullying behaviour can never be underestimated (Oyaziwo, 2008). Limited research has been conducted in South Africa regarding the prevalence and possible long-term effects of chronic bullying at school. This study intended to explore and describe the prevalence of bullying behaviour among a sample of grade 8 learners and the prevalence of previous chronic bullying at school among a sample of young adults in the Nelson Mandela Metropole. In addition, the study aimed to explore and describe the relationship between chronic bullying at school and self-esteem and attachment styles. Finally, the contextual factors which may influence the outcomes of chronic bullying for victims were explored and described. The study was exploratory descriptive in nature and employed a mixed method research design. Participants were selected by means of non-probability sampling. The sample consisted of 225 grade 8 learners at a secondary school in the Nelson Mandela Metropole and 101 young adult participants who had completed their school education in the Nelson Mandela Metropole within the past sixteen years. Data on the demographics of the sample was gathered through the administration of a biographical questionnaire. Furthermore, the Olweus (1996) Bully/Victim Questionnaire was utilized in order to obtain information about the prevalence of bullying behaviours among the participants. James Battle’s (1981) Culture-Free Self-Esteem Inventories were used to measure the construct of self-esteem, and Bartholomew and Horowitz’ (1991) Relationship Questionnaire was employed in order to identify the participants’ current attachment styles. Individual semi-structured interviews were later conducted among a sub-set of young adult participants, who had experienced chronic bullying at school, in order to identify the contextual factors which may have influenced the xiii outcomes of their experiences of victimization. Descriptive and inferential statistics, including correlations and multivariate analysis of variance (ANOVA), were utilized in order to analyze the quantitative data. Key findings revealed that eighty-five percent of the grade 8 participants had been involved in bullying behaviours at school this year and ninety-one percent of the young adult participants had been involved in bullying behaviours during some stage of their school careers. No significant relationship was found to exist between bullying and self-esteem in the grade 8 sample. Self-esteem scores did however vary significantly among the victims, bully-victims and bystanders in the young adult sample. Correlational coefficients confirmed that there was a significant relationship between previous chronic bullying at school and the total self-esteem scores of participants in the young adult sample. Findings also showed that there was no significant relationship between bullying and attachment in either of the samples in this study. Finally, qualitative results revealed that a number of contextual factors influenced the outcomes of chronic bullying at school for the sub-set of young adult victims. These factors included: The nature, frequency and duration of the bullying behaviour, the victims’ social support at the time as well as the victims’ personal characteristics

Knowledge of Medicaid Expansion to Recent and Undocumented Immigrants Among Oregon Mexican-origin Latinos: (Work in Progress)

Background Recent and undocumented immigrants are explicitly excluded from federal Medicaid and state insurance exchanges. The first phase of Healthier Oregon was implemented in July 2022 and expanded Medicaid (OHP) benefits to undocumented immigrants ages 19-25 or 55 and older. The second phase was implemented in July 2023 and extended benefits to everyone regardless of age. We assessed understanding of Healthier Oregon among Mexican-origin Latinos. We hypothesize that many potentially eligible people may not know about the program, if they qualify, or how to apply. Methods This is a cross-sectional study in collaboration with the General Consulate of Mexico. Our team has developed a 19-item cross-sectional survey. This survey includes socio-demographic items and knowledge about Healthier Oregon. Study participants are individuals who are 18 and older, reside in Oregon, and self-identify as Latino/as. We will use descriptive and multivariable statistics to describe our sample, awareness of the Healthier Oregon program, experience enrolling, and factors associated with awareness of Healthier Oregon. Results We have recruited 234 out of 500 planned participants to date. Analyses are ongoing and we will have preliminary data for the SPH conference The study results will be disseminated with the Consulate of Mexico, other local partners, and in a scientific publication. Public Health Significance Recent and undocumented immigrants are explicitly excluded from Medicaid. Oregon has passed legislation to fill this gap. Understanding awareness of the program will provide insight into ways to improve outreach and communication and improve enrollment by eligible individuals

Contribuições das Tecnologias Educativas Digitais no Ensino e Aprendizagem em Enfermagem: revisão sistemática sem metanálise

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências da Saúde. Enfermagem.A educação no mundo atual exige dos educadores uma constante evolução nas metodologias que incentivam alunos dos mais diversos graus de instrução a aprenderem ativamente. O processo de ensino na enfermagem exige que estes futuros profissionais, consigam apreender conteúdos e habilidades de forma crítica e reflexiva, a fim de tomar sempre a melhor decisão possível em condições envolvendo pacientes nas mais diversas situações de saúde. Neste contexto, as tecnologias educativas na formação em saúde vêm sendo cada vez mais utilizadas em intervenções educacionais, no sentido de facilitar a compreensão de diferentes conteúdos, respeitando-se os limites e o ritmo de aprendizagem dos estudantes e proporcionando o protagonismo do aluno neste processo. Assim, o objetivo do estudo propõe analisar as contribuições das tecnologias educativas digitais no ensino e aprendizagem em enfermagem, publicadas nos últimos 5 anos. Trata-se de uma revisão sistemática sem metanálise, com abordagem quantitativa. A busca por referências foi realizada nas bases de dados eletrônicas PubMed, SCOPUS, CINAHL, SciELO e LILACS, em agosto de 2018. O desenvolvimento do estudo seguiu as seguintes etapas: 1) Enquadrando uma questão para uma revisão, 2) Identificando trabalhos relevantes, 3) Avaliando a qualidade dos estudos, 4) Sumarizando as evidências, e 5) Interpretando os resultados. Como critérios de inclusão foram definidos: estudos originais com desenho quantitativo; estudos que abordam a utilização de tecnologias educativas informatizadas no ensino e aprendizagem de enfermagem; publicados de janeiro/2013 a julho/2018; com resumo e texto completo disponível; publicados nos idiomas inglês, espanhol e português. Foram encontrados 537 artigos na busca inicial, sendo incluídos 11 artigos, após a aplicação dos critérios de inclusão e exclusão. O nível de evidência das publicações foi classificado de acordo com o Instituto Joanna Briggs. Os resultados da revisão revelaram que a maioria dos estudos foi desenvolvido no Brasil (7; 63,63%); publicados nos últimos 3 anos (7; 63,63%) e com classificação de nível de evidencia 2.c - Estudos quase experimentais controlados prospectivamente (9; 81,81%). Os Ambientes virtuais de ensino e aprendizagem (7; 63,63%) e jogos sérios (4; 36,36%), foram as tecnologias mais utilizadas nos estudos analisados. Os estudos apontaram melhorias nos escores de aprendizagem no pós-teste em relação ao pré-teste (p<0,05). Conclui-se que as tecnologias educativas podem promover resultados positivos na aprendizagem de alunos de enfermagem e ainda, que há uma evidente lacuna no desenvolvimento de estudos nesta área, que abordem a criação, implementação e avaliação dos resultados na aprendizagem a partir da aplicação de tecnologias educacionais informatizadas no ensino em enfermagem, sendo este um campo de atuação futura para enfermeiros docentes e pesquisadores

Association of Maternal age 35 years and over and prenatal care utilization, preterm birth, and low birth weight, Mexico 2008–2019

Objective: We compared prenatal care utilization, preterm birth, and low birth weight neonates among women 35 years and older compared to women 20-34 years old in Mexico, 2008-2019. Methods: We used birth certificate data and conducted a historical cohort study of all singleton live births in Mexico from 2008-2019. Study outcomes were inadequate prenatal care (timing of initiation of care and number of visits), preterm birth, and low birth weight. We compared outcomes among women 35-39, 40-44, and 45-49 with births to women 20-34. We used logistic regression to account for individual and contextual confounders. Results: We included a total of N=19,526,922 births; 11.9% (n=2,325,725) were to women 35 and older. Compared to women aged 20 to 34, the oldest (45-49 years old) were more likely to reside in poorer communities, have less education, and be uninsured. The odds of inadequate prenatal care (aOR 1.12 95% CI 1.09-1.15 p Conclusion: Women who deliver at 35 years old and over are a heterogeneous group in Mexico. Being 35 years old and older is associated with increases in preterm birth and low birth weight neonates. Women who give birth between 45-49 may be especially vulnerable
