A Portrait of a Reading Teacher

Teacher knowledge is dynamic and experiential. It is both constructed and reconstructed daily as teachers live out their lives in and out of school (Clandinin and Connelly, 1991). Therefore, listening to teachers\u27 stories can be a valuable avenue to gaining insights into the methods other teachers use to teach children to read. My goal is to share one teacher\u27s story in such a way that readers will reflect on their own stories and examine their practices of reading instruction, their knowledge and beliefs, and how all these elements of teaching are interrelated. It is up to readers to take from this qualitative research those parts which fit their individual professional development needs

Secondary and Postsecondary Teachers\u27 Perceptions of ESL Students\u27 Barriers to College Graduation

Majority of English as second language (ESL) students attending primary and secondary schools in the United States are not considered college ready despite mandated educational strategies aimed at improving language acquisition and academic performance. ESL students are more likely to drop out within the first 2 years of college than their English-speaking peers. The purpose of this qualitative study was to explore educators\u27 perspectives regarding high postsecondary attrition rates of ESL students in Middle Tennessee. Tinto\u27s retention theory provided the framework for the study. Data collection included semistructured interviews with 6 Middle Tennessee public high school teachers and 6 Middle Tennessee college professors from 2- and 4-year public colleges. Interview data were coded and analyzed using the thematic analysis method. Findings revealed 4 major themes: language acquisition, barriers to college graduation, adverse circumstances, and academic achievement. Participants reported a desire for alignment between primary, secondary, and postsecondary education. Findings were used to develop a professional development training curriculum for secondary and postsecondary educators. The project included effective strategies to use in the classroom to increase ESL students\u27 college readiness and college graduation rates. If implemented correctly, this project will positively impact ESL students\u27 language acquisition and academic achievement, but it will also develop a significant professional partnership between K-12 public schools and colleges

The Fragmented Vision of Claude McKay: A Study of His Works

Claude McKay, born in Jamaica in 1890, played a significant role in the development of Black American literature. His search for a Black aesthetic and his poems of defiance gave inspiration to young Black artists hungry to explore new ideas. Their creative spirit flowered into the Harlem Renaissance. But, McKay, whose themes helped to stimulate this movement, was plagued by the very concepts that helped to define it. Throughout his life, he was ambivalent about three things: his Afrocentric universe, his role as rebel spokesman, and his relationship to Jamaica. Already a poet of some consequence in Jamaica, McKay thought of America as a grander arena for his voice, but when he arrived in Charleston, South Carolina in 1912, he was shaken by the intense racism of America. His upbringing in rural Clarendon Hills had not prepared him for what he witnessed. By nature, a proud man, McKay turned his lyrical expression into an instrument that would change the arrogance of the Whites. "Harlem Dancer" and "Invocation" (1917) implied the nobility of African roots and affirmed the superiority of primitivistic value system over Western cultural standards. But in McKay's psyche lay the germ of ambivalence that rejected the code of any "world" not sanctioned by the West. During the years following World War I, when relations between Whites and Blacks were strained, McKay became a rebel spokesman for the masses with his defiant poem "If We Must Die" (1919). It urged oppressed people to stand valiant in the face of defeat. But McKay later denied that the poem spoke for Blacks and further questioned the artistic worth of his other "militant" poems. McKay was also ambivalent about his homeland. Throughout most of his life, he ignored in his writing the political, social, and economic realities of Jamaica and evoked instead the image of an Edenic island that offered him refuge from the complexities of the twentieth century

Cultures of success : how elite students develop and realise aspirations to study medicine

Despite decades of policies to widen participation in medical degrees, students selected for Medicine continue to reflect a socially elite group, rather than the diversity of the communities that graduates will serve. While research has documented experiences of students from disadvantaged backgrounds, this paper examines the “cultures of success” that enable advantaged students to gain entry to medical school. It documents how these students’ school and home environments enable the development and realisation of “aspirational capacity”. Aspirational capacity is not just about having a dream, but also the resources and knowledge to realise one’s dream. The paper also examines a negative side of a narrow aspirational focus. “Aspirational constriction” describes the premature foreclosure of career ambitions, which can have negative implications for both the students and for society, and for less advantaged students, who are effectively excluded from degrees such as Medicine

Management of serology negative human hepatic hydatidosis (caused by Echinococcus granulosus) in a young woman from Bangladesh in a resource-rich setting: A case report

Human cystic echinococcosis (hydatidosis) is a parasitic zoonosis with almost complete worldwide distribution. Echinococcus granulosus, the dog tapeworm, causes hydatidosis which accounts for 95% of human echinococcosis. Although this tapeworm is found in dogs as a definitive host and a number of intermediate hosts, humans are often infected from close contact with infected dogs. Humans are not part of the parasitic lifecycle and serve as accidental hosts. Hydatidosis is an important consideration in the differential diagnosis of hepatic cysts in individuals from endemic areas. Clinicians should be aware of the long incubation period, the high frequency of negative serological tests, and the possibility of intraoperative evaluations of the cyst aspirate being non-diagnostic. We describe a case of serology negative hydatidosis that came to medical attention as an incidental finding in a young woman from Bangladesh. The patient underwent imaging and was then started on albendazole. After several weeks of albendazole, the cyst was punctured, aspirated, injected with hypertonic saline, re-aspirated, and then fully excised. Diagnosis was confirmed by microscopic evaluation of the cyst aspirate. Serological tests for hydatidosis may be negative in patients with early disease and thus should not be used to rule out this disease. Consideration of this diagnosis allows clinicians to avoid the catastrophic spillage of cystic contents risking an anaphylactic reaction, which might prove fatal. Despite World Health Organization hydatidosis staging being based on ultrasound, radiologists in resource-rich setting may prefer MRI in the management and staging of cystic echinococcosis

A Planetary Companion to gamma Cephei A

We report on the detection of a planetary companion in orbit around the primary star of the binary system $\gamma$ Cephei. High precision radial velocity measurements using 4 independent data sets spanning the time interval 1981--2002 reveal long-lived residual radial velocity variations superimposed on the binary orbit that are coherent in phase and amplitude with a period or 2.48 years (906 days) and a semi-amplitude of 27.5 m s$^{-1}$. We performed a careful analysis of our Ca II H & K S-index measurements, spectral line bisectors, and {\it Hipparcos} photometry. We found no significant variations in these quantities with the 906-d period. We also re-analyzed the Ca II $\lambda$8662 {\AA} measurements of Walker et al. (1992) which showed possible periodic variations with the ``planet'' period when first published. This analysis shows that periodic Ca II equivalent width variations were only present during 1986.5 -- 1992 and absent during 1981--1986.5. Furthermore, a refined period for the Ca II $\lambda$8662 {\AA} variations is 2.14 yrs, significantly less than residual radial velocity period. The most likely explanation of the residual radial velocity variations is a planetary mass companion with $M$ sin $i$ = 1.7 $M_{Jupiter}$ and an orbital semi-major axis of $a_2$ $=$ 2.13 AU. This supports the planet hypothesis for the residual radial velocity variations for $\gamma$ Cep first suggested by Walker et al. (1992). With an estimated binary orbital period of 57 years $\gamma$ Cep is the shortest period binary system in which an extrasolar planet has been found. This system may provide insights into the relationship between planetary and binary star formation.Comment: 19 pages, 15 figures, accepted in Ap. J. Includes additional data and improved orbital solutio

Perceptions of Environmental Supports for Physical Activity in African American and White Adults in a Rural County in South Carolina

INTRODUCTION: This study examined the association between perceptions of social and safety-related environmental attributes and physical activity (PA) and walking in African American and white adults. METHODS: In a random-digit–dial telephone survey, 1165 adults in a rural county in South Carolina answered questions about their perceptions of social and safety-related environmental supports for PA and their overall PA and walking behavior. Social perceptions included whether neighbors could be trusted or were perceived to be physically active. Safety-related perceptions included neighborhood safety, the safety of public recreation facilities, problems with unattended dogs, traffic volume, and streetlight quality. Logistic regression models were used to examine the associations between environmental supports and PA and walking stratified by race. RESULTS: No association between perceived neighborhood environmental supports and PA or walking was observed in African Americans. Among whites, individuals who perceived their neighbors as active were twice (95% confidence interval [CI], 1.19–3.25) as likely to report meeting the recommendation for PA compared with individuals who did not report their neighbors as active. Whites who perceived their neighbors as active were 2.5 times (95% CI, 1.54–4.08) as likely to report meeting the recommendations for walking than whites who did not, and whites who perceived their neighborhoods as safe were 1.8 times (95% CI, 1.03–3.12) as likely to report meeting the recommendations for walking than whites who did not. CONCLUSION: These data indicate that perceptions of certain social and safety-related environmental supports were strongly associated with meeting the recommendations for PA and walking among white but not African American adults

A Portable Electronic Nose For Hydrazine and Monomethyl Hydrazine Detection

The Space Program and military use large quantities Hydrazine (Hz) and monomethyl hydrazine (MMI-I) as rocket propellant. These substances are very toxic and are suspected human carcinogens. The American Conference of Governmental Industrial Hygienist set the threshold limit value to be 10 parts per billion (ppb). Current off-the-shelf portable instruments require 10 to 20 minutes of exposure to detect 10 ppb concentration. This shortcofriing is not acceptable for many operations. A new prototype instrument using a gas sensor array and pattern recognition software technology (i.e., an electronic nose) has demonstrated the ability to identify either Hz or MM}{ and quantify their concentrations at 10 parts per billion in 90 seconds. This paper describes the design of the portable electronic nose (e-nose) instrument, test equipment setup, test protocol, pattern recognition algorithm, concentration estimation method, and laboratory test results
