The use of the Internet in science teaching: a longitudinal study of developments in use by student teachers in England

This paper reports on a longitudinal study of developments in use of the Internet by science student teachers on Post Graduate Certificate of Education (PGCE) courses in five higher education institution – schools partnerships in England. These are one year, full time, teacher training courses for graduate scientists. The aim of the research was to examine changes in attitudes to, and use of, the Internet to support science teaching and the perceived challenges and barriers to practice in schools, against a background of high national expectations reflected in the qualification standards of the teacher education courses. The research has involved nearly 600 student teachers, representing between 7% and 8% of those training on PGCE science courses in England, and has employed mixed methods, with questionnaires serving as the main basis for analysing trends, and focus groups and case studies used to gain deeper insight to the particular issues identified. The process has been an iterative one, with the outcomes of each year's research being used to inform further research and course developments in the institutions involved. The findings indicate that attitudes and confidence in use of the Internet have improved over the period, with evidence of increased application directly in the classroom. However, in addition to some of the generic technological issues that may hinder developments in the use of ICT, there are continuing concerns relating to limited pedagogical guidance and availability of good role models. The implications of this for developments in science teacher education programmes are discussed

The simultaneous presence and expression of human hepatitis C virus (HCV), human herpesvirus-6 (HHV-6), and human immunodeficiency virus-1 (HIV-1) in a single human T-cell

We have developed a system that isolates and replicates HCV in vitro. These isolates are called CIMM-HCV. This system has made it possible to analyze the biology, nature, and extent of HCV variability, among other things. Individuals that are infected with HIV-1 are often also infected with HCV and HHV-6. In addition to HCV, our lab has systems for replicating HIV-1 and HHV-6. We asked whether all these viruses could infect the same cells. We report here the successful infection of a T-cell (CEM) by CIMM-HCV, HHV-6, and HIV-1. PCR analyses demonstrated that the CEM cells were productively infected by HHV-6A. RT-PCR showed that the same cell culture was positive for HCV and HIV-1. Co-infection of a T-cell by all three viruses was confirmed by transmission electron microscopy (TEM). All these viruses are highly cytolytic; therefore, triply-infected cells were short lived. However, HIV-1 and HCV co-infected cells unexpectedly lasted for several weeks. Viral replication was unhindered and the phenomenon of 'dominance' was not observed in our experiments. In addition, CIMM-HCV was present in the perinuclear space, suggesting their possible synthesis in the nucleus. This report is based entirely on viruses produced in vitro in our laboratories. As part of the determinations of host ranges of these viruses, studies were designed to demonstrate the infection of a single cell by these viruses and to study the consequences of this phenomenon. All measurements were made on cultured cells and cell culture supernatants

Electroencephalography as a tool for evidence-based diagnosis and improved outcomes in children with epilepsy in a resource-poor setting

Introduction: Electroencephalography (EEG) remains the most important investigative modality in the diagnostic evaluation of individuals with epilepsy. Children living with epilepsy in the developing world are faced with challenges of lack of access to appropriate diagnostic evaluation and a high risk of misdiagnosis and inappropriate therapy. We appraised EEG studies in a cohort of Nigerian children with epilepsy seen in a tertiary center in order to evaluate access to and the impact of EEG in the diagnostic evaluation of the cases. Methods: Inter-ictal EEG was requested in all cases of pediatric epilepsy seen at the pediatric neurology clinic of the University College Hospital, Ibadan, Nigeria over a period of 18 months. Clinical diagnosis without EEG evaluation was compared with the final diagnosis post- EEG evaluation. Results: A total of 329 EEGs were recorded in 329 children, aged 3months to 16 years, median 61.0 months. Clinical evaluation pre-EEG classified 69.3% of the epilepsies as generalized. The a posteriori EEG evaluations showed a considerably higher proportion of localization-related epilepsies (33.6%). The final evaluation post EEG showed a 21% reduction in the proportion of cases labeled as generalized epilepsy and a 55% increase in cases of localization-related epilepsy(p<0.001). Conclusion: Here we show that there is a high risk of misdiagnosis and therefore the use of inappropriate therapies in children with epilepsy in the absence of EEG evaluation. The implications of our findings in the resource-poor country scenario are key for reducing the burden of care and cost of epilepsy treatment on both the caregivers and the already overloaded tertiary care services.Pan African Medical Journal 2015; 2

Report of the 2020-2021 Strategic Engagement Standing Committee

EXECUTIVE SUMMARY For the American Association of Colleges of Pharmacy (AACP), strategic engagement is critical to the success of colleges and schools of pharmacy in expanding pharmacy and public health practice, meeting programmatic needs, and fulfilling institutional missions. The 2020-2021 Strategic Engagement Standing Committee was charged with identifying effective strategies to leverage the temporary expansion of pharmacist practice capabilities granted during the COVID-19 pandemic for sustained practice. The group was also tasked with looking at ways to partner with the Association of American Medical Colleges (AAMC), our medicine counterparts to develop a plan for collaborating with them to advance interprofessional practice. In this unique year, all standing committees were charged with reading all the reports last year to put President Lin’s charges into perspective with the hopes of carrying over the overall theme and work of the previous years committee. Overall, throughout the COVID-19 pandemic, there have been several expansions on the scope of practice for pharmacists and vary by state. We hope to draw out some of those expansions to see how we can build upon efforts to make those permanent

Studying Underlying Characteristics of Computing and Engineering Student Success (SUCCESS) Survey

This survey was developed to measure underlying factors that may influence student success including personality, community, grit, thriving, identity, mindset, motivation, perceptions of faculty caring, stress, gratitude, self-control, mindfulness, and belongingness. We measure these underlying factors because each engineering and computing student admitted to a university has clear potential for academic and personal success in their undergraduate curriculum based upon admissions criteria. However, while some thrive academically, others struggle in a variety of ways. In our NSF-funded project (1626287/1626185/1626148), we posit that some collection of characteristics—apparently not visible on their admission applications and perhaps not related to their talent or intelligence—is an important piece of the student performance puzzle. We developed a survey to measure various non-cognitive and affective factors that we believe are important for student achievement, academically, personally, and professionally. These non-cognitive and affective factors are representative of multifaceted aspects of undergraduate student success in prior literature. Each of the constructs we chose had validity evidence from prior studies, some within an engineering population. An exploratory and confirmatory factor analysis have been conducted on the original list of items to develop this finalized survey (Scheidt et al., 2018). The survey takes approximately 30 minutes for students to complete. Scheidt, M., & Godwin, A., & Senkpeil, R. R., & Ge, J. S., & Chen, J., & Self, B. P., & Widmann, J. M., & Berger, E. J.

'Redesigning the Education Workforce' Background Paper for Transforming the Education Workforce: Learning Teams for a Learning Generation

The Education Workforce Initiative (EWI) was established in response to a recommendation from the Education Commission’s Learning Generation report to explore new ways of diversifying and strengthening the education workforce. The Transforming the Education Workforce report is one of EWI’s key contributions to catalyzing this thinking. It draws on recent evidence and provides thought leadership on how to rethink the education workforce. For the full report and other supporting documents, please visit EducationWorkforce.org. The Transforming the Education Workforce report was originally commissioned as a set of sequential background papers and thus each paper influenced and references the others. The background papers are written by different authors and cover the rationale for rethinking the education workforce, the design of the education workforce, how it can be strengthened, and political economy and financial considerations. This background paper focuses on new approaches to designing the education workforce and proposes design options for the workforce needed now and in the futur

Parenting, culture, and the development of externalizing behaviors from age 7 to 14 in nine countries

Using multilevel models, we examined mother-, father-, and child-reported (N = 1,336 families) externalizing behavior problem trajectories from age 7 to 14 in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States). The intercept and slope of children\u27s externalizing behavior trajectories varied both across individuals within culture and across cultures, and the variance was larger at the individual level than at the culture level. Mothers’ and children\u27s endorsement of aggression as well as mothers’ authoritarian attitudes predicted higher age 8 intercepts of child externalizing behaviors. Furthermore, prediction from individual-level endorsement of aggression and authoritarian attitudes to more child externalizing behaviors was augmented by prediction from cultural-level endorsement of aggression and authoritarian attitudes, respectively. Cultures in which father-reported endorsement of aggression was higher and both mother- and father-reported authoritarian attitudes were higher also reported more child externalizing behavior problems at age 8. Among fathers, greater attributions regarding uncontrollable success in caregiving situations were associated with steeper declines in externalizing over time. Understanding cultural-level as well as individual-level correlates of children\u27s externalizing behavior offers potential insights into prevention and intervention efforts that can be more effectively targeted at individual children and parents as well as targeted at changing cultural norms that increase the risk of children\u27s and adolescents’ externalizing behavior

The HST/ACS Coma Cluster Survey. II. Data Description and Source Catalogs

The Coma cluster was the target of a HST-ACS Treasury program designed for deep imaging in the F475W and F814W passbands. Although our survey was interrupted by the ACS instrument failure in 2007, the partially completed survey still covers ~50% of the core high-density region in Coma. Observations were performed for 25 fields that extend over a wide range of cluster-centric radii (~1.75 Mpc) with a total coverage area of 274 arcmin^2. The majority of the fields are located near the core region of Coma (19/25 pointings) with six additional fields in the south-west region of the cluster. In this paper we present reprocessed images and SExtractor source catalogs for our survey fields, including a detailed description of the methodology used for object detection and photometry, the subtraction of bright galaxies to measure faint underlying objects, and the use of simulations to assess the photometric accuracy and completeness of our catalogs. We also use simulations to perform aperture corrections for the SExtractor Kron magnitudes based only on the measured source flux and half-light radius. We have performed photometry for ~73,000 unique objects; one-half of our detections are brighter than the 10-sigma point-source detection limit at F814W=25.8 mag (AB). The slight majority of objects (60%) are unresolved or only marginally resolved by ACS. We estimate that Coma members are 5-10% of all source detections, which consist of a large population of unresolved objects (primarily GCs but also UCDs) and a wide variety of extended galaxies from a cD galaxy to dwarf LSB galaxies. The red sequence of Coma member galaxies has a constant slope and dispersion across 9 magnitudes (-21<M_F814W<-13). The initial data release for the HST-ACS Coma Treasury program was made available to the public in 2008 August. The images and catalogs described in this study relate to our second data release.Comment: Accepted for publication in ApJS.
