Developing reading-writing connections; the impact of explicit instruction of literary devices on the quality of children's narrative writing
The purpose of this collaborative schools-university study was to investigate how the explicit instruction of literary devices during designated literacy sessions could improve the quality of children's narrative writing. A guiding question for the study was: Can children's writing can be enhanced by teachers drawing attention to the literary devices used by professional writers or “mentor authors”? The study was conducted with 18 teachers, working as research partners in nine elementary schools over one school year. The research group explored ways of developing children as reflective authors, able to draft and redraft writing in response to peer and teacher feedback. Daily literacy sessions were complemented by weekly writing workshops where students engaged in authorial activity and experienced writers' perspectives and readers' demands (Harwayne, 1992; May, 2004). Methods for data collection included video recording of peer-peer and teacher-led group discussions and audio recording of teacher-child conferences. Samples of children's narrative writing were collected and a comparison was made between the quality of their independent writing at the beginning and end of the research period. The research group documented the importance of peer-peer and teacher-student discourse in the development of children's metalanguage and awareness of audience. The study suggests that reading, discussing, and evaluating mentor texts can have a positive impact on the quality of children's independent writing

A quantitative wildfire risk assessment using a modular approach of geostatistical clustering and regionally distinct valuations of assets—A case study in Oregon
The intensity and scale of wildfires has increased throughout the Pacific Northwest in recent decades, especially within the last decade, destroying vast amounts of valuable resources and assets. This trend is predicted to remain or even magnify due climate change, growing population, increased housing density. Furthermore, the associated stress of prolonged droughts and change in land cover/land use puts more population at risk. We present results of a multi-phase Extension Fire Program Initiative combining fire model results based on worst-case meteorological conditions recorded at 50 weather stations across Oregon with spatially distinct valuations of resources and assets based on regional ecological and socio-economic conditions. Our study focuses on six different Fire Service Areas covering the state of Oregon. We used a geostatistical approach to find weather stations that provide worst-case meteorological input data on record for representative sub-domains. The results provide regionally distinct assessments of potential value loss by wildfire and show that, depending on the region, 12% to 52% of the highest relative risk areas are on private land. This underscores the need to unite strategies and efforts on the landscape scale by including different landowners, managers, and stakeholders of public land and private land efficiently address wildfire damage protection and mitigation. Our risk assessments closely agreed with risks identified during landscape-scale ground projects

Chemical crosslinking and mass spectrometry studies of the structure and dynamics of membrane proteins and receptors.
Membrane proteins make up a diverse and important subset of proteins for which structural information is limited. In this study, chemical cross-linking and mass spectrometry were used to explore the structure of the G-protein-coupled photoreceptor bovine rhodopsin in the dark-state conformation. All experiments were performed in rod outer segment membranes using amino acid 'handles' in the native protein sequence and thus minimizing perturbations to the native protein structure. Cysteine and lysine residues were covalently cross-linked using commercially available reagents with a range of linker arm lengths. Following chemical digestion of cross-linked protein, cross-linked peptides were identified by accurate mass measurement using liquid chromatography-fourier transform mass spectrometry and an automated data analysis pipeline. Assignments were confirmed and, if necessary, resolved, by tandem MS. The relative reactivity of lysine residues participating in cross-links was evaluated by labeling with NHS-esters. A distinct pattern of cross-link formation within the C-terminal domain, and between loop I and the C-terminal domain, emerged. Theoretical distances based on cross-linking were compared to inter-atomic distances determined from the energy-minimized X-ray crystal structure and Monte Carlo conformational search procedures. In general, the observed cross-links can be explained by re-positioning participating side-chains without significantly altering backbone structure. One exception, between C3 16 and K325, requires backbone motion to bring the reactive atoms into sufficient proximity for cross-linking. Evidence from other studies suggests that residues around K325 for a region of high backbone mobility. These findings show that cross-linking studies can provide insight into the structural dynamics of membrane proteins in their native environment

Ações de Prevenção da Deficiência Mental, dirigidas a Gestantes e Recém-Nascidos, no âmbito da Saúde Pública da Grande Vitória-ES
The accomplishment of prevention in Public Health requires a systematized knowledge for the proposition of a program and its evaluation. When it comes to the prevention of Mental Deficiency, which afflicts around 10% of the population, little is known in Brazil. By adopting a methodology for cataloging MD preventive actions in hospitals and health units, with pregnant women and newborns, it was possible to describe and analyze the actions of the public health system in Greater Vitoria/ES, indicating the levels of prevention which were most covered. Preventive actions (PA) of five large public hospitals, nine health units and six health offices, from 1996 to 1997 were studied. Data from 25 interviews show that these places made 51.5% of the 433 possible PA (57.4% of primary prevention and 45.5% of the secondary). Along with the particularization of the action of each municipality and place researched, the obtained data was useful for analyses and possible changes in maternal-infantile health indicators.Faire de la prĂ©vention dans la santĂ© publique est conditionnĂ© par une très bonne connaissance afin de proposer des programmes et les Ă©valuer. Au BrĂ©sil, on sait peu de choses sur la prĂ©vention de la dĂ©ficience mentale, qui atteint pourtant 10 % de la population. Adoptant une mĂ©thodologie et pour faire un catalogue des actions prĂ©ventives de dĂ©ficience mentale dans les hĂ´pitaux et les unitĂ©s de santĂ©, pour les femmes enceintes et les nouveau-nĂ©s, on a pu dĂ©crire et analyser les actions de santĂ© publique dans la ville de Grande Vitoria (État du Espirito Santo), indiquant le niveau de prĂ©vention les plus couverts. On a regroupĂ© les actions de prĂ©vention de cinq hĂ´pitaux publics importants, neuf (31 %) unitĂ©s de santĂ© et six bureaux centralisateurs, entre 1996 et 97. Les donnĂ©es de vingt-cinq entrevues montrent que ces locaux rĂ©alisent 51,5 % des 433 actions de prĂ©vention possibles (57,4 % de prĂ©vention primaire et 45,5 % de secondaire). En dĂ©taillant les rĂ©alisations de chaque municipalitĂ© et local Ă©tudiĂ©, les chiffres fournissent des ressources pour des analyses et les modifications possibles dans les indicateurs de santĂ© maternelle et infantile.Fazer prevenção em SaĂşde PĂşblica implica em conhecimento sistematizado para a proposição de programas e sua avaliação.
