Improving Reading: A Case Study of the Accelerated Reader Program

Fidelity of program implementation of the Accelerated Reader (AR) program in relation to fourth-grade students’ achievement in reading was investigated. The relationship among students’ motivation to read, the role of parental support, and the reading success of students as measured by the fourth-grade end-of-grade reading test was also examined. Implementation fidelity of the AR program was determined through researcher observations and completion of an AR Implementation Checklist by participating teachers. Motivation to read was determined by administration of the ERAS to fourth-grade students. Parental support was measured through use of a parent survey and a teacher perceptions survey. Principals and the district English language arts curriculum coordinator were interviewed to determine expectations. Reading EOG scores for third and fourth grades for the same students were examined to determine growth in reading proficiency. The results indicated that there was no significant relationship among fidelity of program implementation, motivation to read, parental support, AR scores, and EOG reading test scores

TIDieR-PHP: a reporting guideline for population health and policy interventions

We lack guidance on how to describe population health and policy (PHP) interventions in reports of evaluation studies. PHP interventions are legal, fiscal, structural, organisational, environmental, and policy interventions such as the regulation of unhealthy commodities, health service reorganisation, changes in welfare policy, and neighbourhood improvement schemes. Many PHP interventions have characteristics that are important for their implementation and success but are not adequately captured in the original Template for Intervention Description and Replication (TIDieR) checklist. This article describes the development of a revised reporting template for PHP interventions (TIDieR-PHP) and presents the checklist with examples for each ite

The Impact of Reflective Practice on Teacher Candidates\u27 Learning

Reflection is a high impact practice that develops teacher candidates’ learning. Critical reflection requires teacher candidates to continually examine their own thoughts, perspectives, biases, and actions. Reflective practice facilitates the development of new knowledge, skills, and dispositions in teacher candidates by fostering critical contemplation of actions in a real-world environment. Reflection practice is specifically used when students study education in a university course and apply what they learn in a related field experience in a K-12 school. This study was conducted in order to determine the impact of reflective practice on teacher candidates enrolled in a course focused on developmental sciences in a context of poverty. Results demonstrate what level of research is required to prepare teacher candidates to make instructional decisions as well as become self-aware of their perspectives and attitudes in teaching

Continuous tank reactor synthesis of highly substituted sulphobutylether β-cyclodextrins

Batch synthesis of sulphobutyl ether β-cyclodextrin (also known as SBE-β-CD or SBECD) is a process effectively divided into three main stages, i.e. initial reagent dissolution, a sulphoalkylation reaction and final reaction quenching. This reaction is followed by downstream processing and purification, and ultimate isolation of the solid SBECD material. However, a feature associated with using this synthetic method is that a high proportion of lower substituted SBECD is observed. There is therefore a need to provide an improved synthetic method for producing higher substituted cyclodextrins. The authors here present a Continuous Tank Reactor (CTR) method for preparing sulphobutyl ether-cyclodextrins. The method comprises first contacting cyclodextrin with a base to form activated cyclodextrin. The method then involves separately contacting the activated cyclodextrin with an 1,4-butane sultone to form sulphoalkyl ether-cyclodextrin. The activation reaction is carried out in batch synthesis mode and the sulphoalkylation reaction is carried out under continuous flow conditions resulting in a novel method for the synthesis of highly derivatised cyclodextrins. The work is particularly concerned with producing controlled substitution in sulphobutyl ether β-cyclodextrins and novel compositions of highly substituted sulphoalkyl ether β-cyclodextrins are described

ARomatase Inhibition plus/minus Src-inhibitor SaracaTinib (AZD0530) in Advanced breast CAncer Therapy (ARISTACAT): a randomised phase II study

PURPOSE: The development of oestrogen resistance is a major challenge in managing hormone-sensitive metastatic breast cancer. Saracatinib (AZD0530), an oral Src kinase inhibitor, prevents oestrogen resistance in animal models and reduces osteoclast activity. We aimed to evaluate the efficacy of saracatinib addition to aromatase inhibitors (AI) in patients with hormone receptor-positive metastatic breast cancer. METHODS: This phase II multicentre double-blinded randomised trial allocated post-menopausal women to AI with either saracatinib or placebo (1:1 ratio). Patients were stratified into an "AI-sensitive/naïve" group who received anastrozole and "prior-AI" group who received exemestane. Primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate (ORR) and toxicity. RESULTS: 140 patients were randomised from 20 UK centres to saracatinib/AI (n = 69) or placebo/AI (n = 71). Saracatinib was not associated with an improved PFS (3.7 months v. 5.6 months placebo/AI) and did not reduce likelihood of bony progression. There was no benefit in OS or ORR. Effects were consistent in "AI-sensitive/naive" and "prior-AI" sub-groups. Saracatinib was well tolerated with dose reductions in 16% and the main side effects were gastrointestinal, hypophosphatemia and rash. CONCLUSION: Saracatinib did not improve outcomes in post-menopausal women with metastatic breast cancer. There was no observed beneficial effect on bone metastases. CRUKE/11/023, ISRCTN23804370

The distribution and population dynamics of the honey bee pathogens Crithidia mellificae and Lotmaria passim in New Zealand

The honey bee Apis mellifera is experiencing colony losses across the world, this is not the first time in history colony losses have been reported. New molecular detection methods such as real-time PCR allow the detection and analysis of pathogens present in colonies, quickly and reliably. Of the pathogens that the honey bee is host to, trypanosomes are one of the least understood and trypanosome interactions within the honey bee host remain largely unknown. Using the bumble bee as a model for this host-parasite relationship. The trypanosome C. bombi is known to cause a reduced ability to gain nutrients from food and an overall decrease in efficiency of queens in founding colonies in spring. These negative correlations are significant enough in the bumble bee to warrant investigation into trypanosomes in the honey bee. The trypanosome C. mellificae was first described in the honey bee in 1967. A screening study in 2009 included a test for and detected the trypanosome in modern honey bee samples. In 2013 C. mellificae was identified as a contributory factor to overwintering colony losses when co-infected with N. ceranae. Following studies detected trypanosomes and led to the characterisation of a new species, L. passim in 2013. Lotmaria passim was first detected in New Zealand in 2014 however no subsequent studies had been undertaken to identify the distribution and dynamics of trypanosomes in New Zealand honey bee colonies. My goal in this study was to identify the presence of trypanosomes in New Zealand. In an overview study of 47 honey bee colonies from across New Zealand, 46 were positive for the L. passim species. Identified by sequencing of the GAPDH gene. A yearlong study of 15 colonies revealed that the infection rate of L. passim was consistent throughout the year and very low genetic variation was detected. Lotmaria passim was detected in all parts of New Zealand sampled in this study and often in high levels. A positive correlation was detected when L. passim was present in addition to N. apis. There was no detection of C. mellificae in my study. The lack of detection of C. mellificae may suggest that the species is not present, or that it is in such low levels it cannot yet be detected. In parallel to this trypanosome study two Nosema spp. and DWV were also examined. Nosema apis was found to be more prevalent than N. ceranae, which was not present in any South Island samples. A strong positive correlation was detected between the two Nosema spp. DWV showed a high level of variation likely a reflection of differing Varroa management practices in apiaries in this study. This study of trypanosomes is the first of its kind in New Zealand identifying the presence and population dynamics of L. passim. This in conjunction with data on Nosema spp. and DWV will be of value to the New Zealand apiculture industry and contribute to global honey bee health studies

Are you digital native or a digital immigrant and how does this impact your teaching?

Prioritizing the use of effective teaching strategies in the collegiate classroom has been an emphasis for several decades. What has changed is the learning paradigm of the millennial generation. This generation offers unique strengths and challenges as we strive to enhance our teaching effectiveness in an effort to move toward student-centered learning. Having a comprehensive understanding of the millennial generation and their characteristics, priorities, and goals will encourage educators to focus energies in the most appropriate areas that will produce high levels of motivation and achievement. Using the research of Chickering and Gamson’s (1987) work on effective teaching, the seven principles for good practice will be reviewed with an emphasis on our new generation of learners, the millennials. This seminar seeks to promote an understanding of our students and a renewed commitment to create and implement engaging lessons that will enrich our students’ knowledge and foster their dedication to their future profession.
