Education and work in service of the nation: Canadian and Australian girls' fiction, 1908-1921

This chapter compares early twentieth-century Australian novels by Ethel Turner, Mary Grant Bruce, and Lilian Turner to Canadian novels by Nellie McClung and L.M. Montgomery to demonstrate important differences in attitudes towards education and work. Girls’ fiction in these white settler colonies has many similarities, containing strong ideals related to domesticity, education, employment, and femininity. In the Canadian fiction, attitudes towards women’s higher education and employement are generally much more positive. Although both Australian and Canadian girls’ fiction typically conclude with marriage, Montgomery’s Anne of Green Gables and Nellie McClung’s Pearlie Watson are offered the opportunity to pursue higher education and use this education to teach others. In contrast, Lilian Turner’s Paradise and the Perrys, Ethel Turner’s Fair Ines, and Mary Grant Bruce’s ’Possum emphasise the importance of domesticity while also showing how girls sought to earn income without leaving home. Through our comparison of these Canadian and Australian novels, all published between 1908 and 1921, we demonstrate how the different feminine ideals embodied through these heroines are inevitably intertwined with the needs of the nation

"My blarsted greenstone throne!" Māori princesses and nationhood in New Zealand fiction for girls

This chapter focuses on Isabel Peacocke’s The Runaway Princess (1929) and Mona Tracy’s short story collection, Piriki’s Princess and Other Stories of New Zealand (1925), which incorporates a swathe of princesses, Māori and Pākehā. The princesses to be discussed in this chapter occupy liminal states: between Māori and Pākehā, child and adult, individual and collective subjects. Whether Māori and Pākehā, they figure in narratives of identity-formation that implicitly or explicitly incorporated comparisons between Māori and Pākehā. This chapter tracks this continuum of representations working from Māori to Pākehā and beginning with two Māori princesses who feature in Tracy’s stories ‘A Deserted Settlement’ and ‘Four Tons of Flax’.

The British empire and Australian girls' annuals

This article explores two series of girls' annuals: the Empire Annual for Australian Girls (1909-30), published by the Religious Tract Society, and the Australian Girl's Annual (1910-3?), published by Cassell. Although both series were seemingly targeted at Australian girls, they were published in Britain before being given a new title and sent to the colonies. This article examines the implications of these British models of girlhood for their explicitly colonial girl readers. The British publishers of these annuals addressed an apparently homogenous readership comprised of girls from white settler colonies and Britain without attempting to customize the contents of their books for different audiences. In both fiction and illustrations, the annuals simultaneously employed and produced a British model of girlhood that was attractive to Australian girl readers.

Lunch frequency among adolescents: associations with sociodemographic factors and school characteristics

Objective: To investigate: (i) how lunch frequency of adolescents varies between schools and between classes within schools; (ii) the associations between frequency of lunch and individual sociodemographic factors and school characteristics; and (iii) if any observed associations between lunch frequency and school characteristics vary by gender and age groups. Design: Cross-sectional study in which students and school headmasters completed self-administered questionnaires. Associations were estimated by multilevel multivariate logistic regression. Setting: The Danish arm of the Health Behaviour in School-Aged Children study 2010. Subjects: Students (n 4922) aged 11, 13 and 15 years attending a random sample of seventy-three schools. Results: The school-level and class-level variations in low lunch frequency were small (intraclass correlation coefficient <2·1 %). At the individual level, low lunch frequency was most common among students who were boys, 13- and 15-year-olds, from medium and low family social class, descendants of immigrants, living in a single-parent family and in a reconstructed family. School-level analyses suggested that having access to a canteen at school was associated with low lunch frequency (OR=1·47; 95% CI 1·14, 1·89). Likewise not having an adult present during lunch breaks was associated with low lunch frequency (OR=1·44; 95% CI 1·18, 1·75). Cross-level interactions suggested that these associations differed by age group. Conclusions: Lunch frequency among Danish students appears to be largely influenced by sociodemographic factors. Additionally, the presence of an adult during lunch breaks promotes frequent lunch consumption while availability of a canteen may discourage frequent lunch consumption. These findings vary between older and younger students.

Targeting VEGF with LNA-stabilized G-rich oligonucleotide for efficient breast cancer inhibition

In this study, we investigated the efficacy of an LNA (locked nucleic acid)-modified DNA aptamer named RNV66 targeting VEGF against various breast cancer cell lines. Our results demonstrate that RNV66 efficiently inhibits breast cancer cell proliferation both in vitro and in vivo. Introduction of LNA nucleotides were crucial for higher efficacy. Furthermore, the binding interaction of RNV66 with VEGF was investigated using molecular dynamic simulations leading to the first computational model of the LNA aptamer-VEGF complex blocking its interaction with VEGF-receptor.

The human side of project management - an investigation of critical chain concepts in the Argentinean Project Environment

The global marketplace is rapidly intensifying. Longer product sales lives, greater profit margins or simply survival, is dependent on management¿s ability to create and lead change. Project Management has become an important competency, combined with other business practices to adapt to the trend of changing conditions. Critical Chain is a relatively new project methodology, elaborated by Eliyahu Goldratt in order to complete projects faster, make more efficient use of resources and securing the project deliverables. The methodology is based on the assumption that traditional project techniques such as CPM and PERT, do not recognize critical human behavior. The methodology claims that many project failures are a direct result of how safety is built into the task delivery times, and then wasted by human behavior such as Student Syndrome, Parkinson Law and Multitasking. However, there has been little or no previous research regarding this topic in the Argentine marketplace. This study intended to investigate to what extent the human behavior concepts of critical chain project management are present, by performing in-depth interviews with Argentine project stakeholders. It appears that the four human behavior concepts are present in Argentina and that the majority of Argentine companies are yet to apply project management techniques.

Dosimetry and cost of imaging osseointegrated implants with film-based and computed tomography

Thermoluminescent dosimeters were used to measure radiation doses at craniofacial sites in a tissue-equivalent phantom during film-based multidirectional tomography with the Tomax Ultrascan (Incubation Industries, Ivyland, Pa.) and during computed tomography with the Elscint Excel 2400 (Elscint Corp., Tel Aviv, Israel). Mean absorbed doses for presurgical mandibular and maxillary canine and molar implant assessments were converted to equivalent doses, which were then multipied by published weighting factors and summed to give effective doses. The computed tomgraphy device consistently delivered higher doses than the Tomax Ultrascan to all anatomic locations; the differences were most pronounced when only one or two implant sites were evaluated. The reasons for the dose disparities are considered both anatomically and procedurally. A survey of examination cost revealed film-based multidirectional tomography to be less expensive than computed tomography.

Pharmacokinetics of dexmedetomidine administered intravenously in isofluraneanesthetized cats

Objective-To determine the pharmacokinetics of dexmedetomidine administered as a short-duration IV infusion in isoflurane-anesthetized cats. Animals-6 healthy adult domestic female cats. Procedures-Dexmedetomidine hydrochloride was injected IV (10 μg/kg over 5 minutes [rate, 2 μg/kg/min]) in isoflurane-anesthetized cats. Blood samples were obtained immediately prior to and at 1, 2, 5, 6, 7, 10, 15, 30, 60, 90, 120, 240, and 480 minutes following the start of the IV infusion. Collected blood samples were transferred to tubes containing EDTA, immediately placed on ice, and then centrifuged at 3,901 X g for 10 minutes at 4°C. The plasma was harvested and stored at -20°C until analyzed. Plasma dexmedetomidine concentrations were determined by means of liquid chromatography-mass spectrometry. Dexmedetomidine plasma concentration-time data were fitted to compartmental models. Results-A 2-compartment model with input in and elimination from the central compartment best described the disposition of dexmedetomidine administered via short-duration IV infusion in isoflurane-anesthetized cats. Weighted mean ± SEM apparent volume of distribution of the central compartment and apparent volume of distribution at steady-state were 402 ± 47 mL/kg and 1,701 ± 200 mL/kg, respectively; clearance and terminal half-life (harmonic mean ± jackknife pseudo-SD) were 6.3 ± 2.8 mL/min/kg and 198 ± 75 minutes, respectively. The area under the plasma concentration curve and maximal plasma concentration were 1,061 ± 292 min·ng/mL and 17.6 ± 1.8 ng/mL, respectively. Conclusions and Clinical Relevance-Disposition of dexmedetomidine administered via short-duration IV infusion in isoflurane-anesthetized cats was characterized by a moderate clearance and a long terminal half-life.

Inverse Modeling of GPS Multipath for Snow Depth Estimation-Part II: Application and Validation

GPS multipath reflectometry (GPS-MR) is a technique that uses geodetic quality GPS receivers to estimate snow depth. The accuracy and precision of GPS-MR retrievals are evaluated at three different sites: grasslands, alpine, and forested. The assessment yields a correlation of 0.98 and an rms error of 6-8 cm for observed snow depths of up to 2.5 m. GPS-MR underestimates in situ snow depth by 10%-15% at these three sites, although the validation methods do not measure the same footprint as GPS-MR.

Nitroglycerin drives endothelial nitric oxide synthase activation via the phosphatidylinositol 3-kinase/protein kinase B pathway

Nitroglycerin (GIN) has been clinically used to treat angina pectoris and acute heart episodes for over 100 years. The effects of GTN have long been recognized and active research has contributed to the unraveling of numerous metabolic routes capable of converting GIN to the potent vasoactive messenger nitric oxide. Recently, the mechanism by which minute doses of GIN elicit robust pharmacological responses was revisited and eNOS activation was implicated as an important route mediating vasodilation induced by low GTN doses (1-50 nM). Here, we demonstrate that at such concentrations the pharmacologic effects of nitroglycerin are largely dependent on the phosphatidylinositol 3-kinase, Akt/PKB, and phosphatase and tensin homolog deleted on chromosome 10 (PTEN) signal transduction axis. Furthermore, we demonstrate that nitroglycerin-dependent accumulation of 3,4,5-InsP(3), probably because of inhibition of PTEN, is important for eNOS activation, conferring a mechanistic basis for GIN pharmacological action at pharmacologically relevant doses.

Conhecimento médico sobre as imunodeficiências primárias na cidade de São Paulo, Brasil

OBJETIVO: Avaliar o conhecimento médico sobre as imunodeficiências primárias na cidade de São Paulo (SP). MÉTODOS: Um questionário de 14 questões sobre as imunodeficiências primárias foi aplicado a médicos que trabalhavam em hospitais gerais. Uma das questões apresentava 25 situações clínicas que poderiam ou não estar associadas às imunodeficiências primárias, e a porcentagem de respostas apropriadas gerou um indicador de conhecimento. RESULTADOS: Participaram do estudo 746 médicos, dentre os quais 215 pediatras (28,8%), 244 cirurgiões (32,7%) e 287 clínicos (38,5%). Cerca de 70% dos médicos responderam ter aprendido sobre as imunodeficiências primárias na graduação ou na residência médica. O atendimento a pacientes que usam antibióticos com frequência foi relatado por 75% dos médicos, mas apenas 34,1% já haviam investigado algum paciente e 77,8% não conheciam os dez sinais de alerta para as imunodeficiências primárias. O indicador de conhecimento obtido apresentou uma média de 45,72% (±17,87). Apenas 26,6% dos pediatras e 6,6% tanto dos clínicos quanto dos cirurgiões apresentaram indicador de conhecimento de pelo menos 67% (equivalente à resposta apropriada em dois terços das situações clínicas). CONCLUSÃO: Há uma deficiência no conhecimento médico das imunodeficiências primárias na cidade de São Paulo, mesmo entre os pediatras, a despeito do maior contato com o tema nos últimos anos. A melhora da informação sobre as imunodeficiências primárias entre a comunidade médica é um importante passo para o diagnóstico e o tratamento precoces dessas doenças.
