To share activities to support preservice secondary mathematics teachers’ (PSMTs) participation questioning discourse, which consists of (a) modeling and engaging students in mathematical discourse and activity, and (b) supporting and assessing students’ development of conceptual understanding.

PSMTs typically struggle to develop fluency in participation questioning discourse, despite having it modeled for them by expert teachers in mathematics education courses. Using Gee’s Discourse Theory to conceptualize this problem, we developed the iterative model of See it, Try it and Reflect on it (STaR) to create learning activities in a methods course that engage PSMTs in viewing and reflecting on videotaped mathematics lessons.

PSMTs increased their fluency in participation questioning discourse through viewing and reflecting on videotaped lessons using the STaR iterative model.

The STaR model is a promising framework that can be used to design learning activities to help preservice and inservice teachers acquire fluency in discipline-specific pedagogical Discourses.

Purpose – This study analyzed individual factors of race and dual eligibility on emergency room (ER) utilization of older adult Medicare patients treated by RHCs in CMS Region 4.

Methodology/approach – A prospective, longitudinal design was employed to analyze health disparities that potentially exist among RHC Medicare beneficiary patients (+65) in terms of ER use. The years of investigation were 2010 through 2012, using mixed multilevel, binary logistic regression.

Findings – This study found that dual eligible RHC patients utilized ER services at higher rates than nondual eligible, Medicare only RHC patients at: 77%, 80%, and 66%, in 2010, 2011, and 2012, respectively; and above the White reference group, Black RHC Medicare patients utilized ER services at higher rates of: 18%, 20%, and 34%, in 2010, 2011, and 2012, respectively.

Research limitations/implications – Regarding limitations, cohort data observations within the window of 3 years were only analyzed; regarding generalizability, in different CMS regions, results will likely vary; and linking other variables together in the study was limited by the accessible data. Future research should consider these limitations, and attempt to refine. The findings support that dual Medicare and Medicaid eligibility, as a proxy measure of socioeconomic status, and race continue to influence higher rates of ER utilization in CMS Region 4.

Originality/value – In terms of ER utilization disparities, persistently, as recent as 2012, Black, dual eligible RHC Medicare beneficiary patients age 65 years and over may be twice as likely to utilize ER services for care than their counterparts in the Southeastern United States.

The fluorescence of organic dyes is associated with the individual molecules of the dyes, and in order for them to fluoresce efficiently, they must be molecularly dissolved and in fairly low concentrations from about 1 to 4%. In the pure solid state or in very concentrated solutions the dyes have almost no fluorescence and appear as dark or dirty red, yellow and green powders or solutions. The individual molecules of the dyes are so close together that they simply quench or reabsorb their own fluorescent light. Since the dyes are organic in nature it is necessary to have a medium or carrier in order to put them into solution, and to have a pigment it is necessary that this medium be a solid. The type of material which meets these requirements for the dyes is an organic resin, and daylight fluorescent pigments are actually transparent organic resin particles containing dyes in solution which are capable of fluorescing.

Within the past few years, responsible educators, librarians, parents, counselors, social workers, therapists, and religious groups of all sexual persuasions and lifestyles have recognized the need for readily available reading material for lesbian and gay youth. Unfortunately, this material is often buried, because it is embedded in larger works. To meet this need, I have compiled and annotated 100 of the best works for young homosexuals, bisexuals, and heterosexuals. I have also included a few of the best works currently available on heterosexuality as a much needed source of knowledge for all young adults whether they are gay or straight, whether they remain childless or eventually become parents.

ABM Chemicals Ltd is exhibiting its range of photosensitisers for uv curing including the Glocure benzoin ethers. These highly cost effective materials ensure maximum utilisation of uv energy for the polymerisation process.

Data provided by the U.S. Navy were analysed to examine differences in successful flight training completion between men and women and among minorities. Results indicated that there were not significant differences between men and women with regard to attrition; however differences in the non‐completion of flight training did exist among those of different racial backgrounds. Consistent with previous studies, white aviators were found to have consistently higher graduation rates than all other racial groups and Blacks were found to have significantly higher rates of attrition than Hispanic student aviators. Recommendations to seek greater understanding of these discrepancies, including the potential for unfair discrimination, are made.

IT is nearly three and a half centuries since John Donne, preaching in St. Paul's Cathedral, of which he had recently become Dean, said: ‘Some men, by the benefit of this light of Reason, have found out things profitable and use‐ful to the whole world; as in particular Printing, by which the learning of the whole world is communicable to one another, and our minds and inventions, our wits and compositions, may trade and have commerce together, and we may participate of one another's understandings, as well as of our Clothes, Wines, Oyles and other Merchandize.’
