Zoned out: Conflict and perceived threat in a rural-urban fringe area

Zoning and other restrictive land use policies are quite common in the United States and are frequently enacted as a response to the rapid growth and change within a city or county. Past research on zoning has primarily examined the positive and negative consequences of zoning ordinances, often focusing the analysis on neighborhood change. This study inductively examines the conflict that emerged in one county when new zoning ordinances were proposed through an in-depth analysis of nearly 300 newspaper forums, observations of three public hearings, and interviews with key informants. Concerned with activists on both sides of the zoning issue, this study explores reasons for support and opposition to zoning in rural-urban fringe county. Findings illustrate how perceived threat is associated with what individuals in the community recognize the goals and consequences of zoning policy to be. Implications of the findings and future research are also discussed

A Comparative Case Study of Factors Distinguishing Between High and Low-Performance on Reading Achievement in Elementary Rural Appalachian Schools

This qualitative comparative case study identified factors that distinguish between high and low-performance on reading achievement in elementary rural Appalachian schools. This study determined the most effective instructional reading strategies, as well as other influential factors, implemented by school districts in the rural Appalachia area with similar student demographics and economic disadvantages. Data were collected through interview questions to assess the staffs\u27 perceptions of their school\u27s instructional program, leadership strategies, and teaching methods. The researcher also conducted observations of classrooms during reading instruction to determine practices being used. Results indicate high teacher morale, teacher efficacy, supportive leadership, meaningful professional development, and instructional strategies such as: explicit small group instruction, uninterrupted time spent on reading instruction, and inclusion of literacy centers are all variables that discriminate between these high and low performing schools

Thermal Evolution of the Mid-Crust From the Himalayan Orogen

The Haimanta Group, at the top of the exhumed mid-crust in the western Himalaya (Sutlej valley), underwent prograde metamorphism to depths of 25 to 30 km at c. 30 Ma. Initial exhumation of the Haimanta Group was accompanied by further heating, from 610-620 °C up to 660 °C at c. 23 Ma; further exhumation (at c. 1.3 mm/yr) to a depth of c. 7 km during the Early Miocene resulted in cooling to 300-350 °C. Meanwhile, the underlying Greater Himalayan Sequence (GHS) was rapidly exhumed due to coeval extension on the South Tibetan Detachment above and compression on the Main Central Thrust below. The Jutogh Group, with Palaeoproterozoic (c. 1810 Ma) leucogranites characteristic of the Lesser Himalayan Sequence, was buried and metamorphosed beneath the overthrust GHS, and involved the partial recrystallisation of uraninite in leucogranite at 11 Ma. The Chekha Formation (Radi klippe) in the eastern Himalaya (Bhutan), in a similar structural position to the Haimanta Group, also reveals a history of Oligocene prograde metamorphism, to c. 7 kbars and 550-620°C at c. 22 Ma, synchronous with prograde metamorphism in the underlying GHS (peak metamorphism, c. 24 Ma). Comparable metamorphism and deformation in the Haimanta Group and Chekha Formation, distinct from that in the underlying GHS, is the result of a common tectono-thermal process in the early evolution of the orogen. Pressure-temperature-time data from the metamorphic core are generally consistent with the channel flow model, but may be equally compatible with contesting models. Uranium(-thorium)-lead isotope analysis of monazite (which formed above 580 °C after, or during the final stages of garnet growth, and probably via the breakdown of allanite and apatite) provided a robust method for dating prograde-peak metamorphism. Samarium-neodymium garnet geochronology was hampered by Ca-bearing Nd-rich garnet inclusions (e.g. allanite)

Adoption and Foster Care by Gay and Lesbian Parents in the United States

Discussion and debate about adoption and foster care by gay, lesbian, and bisexual (GLB) parents occurs frequently among child welfare policymakers, social service agencies, and social workers. They all need better information about GLB adoptive and foster parents and their children as they make individual and policy-level decisions about placement of children with GLB parents. This report provides new information on GLB adoption and foster care from the U.S. Census 2000, the National Survey of Family Growth (2002), and the Adoption and Foster Care Analysis and Reporting System (2004)

Titanium in Muscovite, Biotite, and Hornblende: Modeling, Thermometry, and Rutile Activities of Metapelites and Amphibolites

Reactions involving the VITiIVAl-VIAlIVSi exchange in muscovite, biotite, and hornblende were calibrated thermodynamically using a set of experimental and natural data in rutile-plus quartz/coesite-bearing assemblages. The specific respective reactions are K(Al2)(AlSi3)O10(OH)2 + TiO2 = K(AlTi)(Al2Si2)O10(OH)2 + SiO2 (R1) K(□MgAl)Si4O10(OH)2 + TiO2 = K(□MgTi)AlSi3O10(OH)2 + SiO2 (R2) Ca2Mg3Al2Al2Si6O22(OH)2 + 2TiO2 = Ca2Mg3Ti2Al4Si4O22(OH)2 + 2SiO2. (R3) Ideal mixing on octahedral or octahedral plus tetrahedral sites and a non-ideal van Laar solution model yield the best regression results for thermodynamic fit parameters, with R2 values of 0.98–1.00. Isopleths of the equilibrium constant (Keq) show minimal pressure dependencies of \u3c1 \u3e°C/kbar, implying that the equilibria are poor barometers. Model reproducibility of the ideal portion of the equilibrium constant (Kid) is excellent (ca. ±0.1 to 0.3, 2σ), but the absolute value of the combined term ΔS+Kid is quite small (absolute values from 0 to 4), so calibration residuals propagate to temperature errors \u3e±50–100 °C, 1σ. Whereas the consistency of a mica or hornblende composition with a known T can be evaluated precisely, Ti chemistry in these reactions is sensitive to composition and does not resolve T (or P) well. The activity of TiO2 in rutile [a(rt)] was also evaluated using both the garnet-rutile-ilmenite-plagioclase-quartz (GRIPS) equilibrium and our new calibrations in rutile-absent, ilmenite-bearing rocks whose peak P-T conditions are otherwise known. Metapelites have average a(rt) of 0.9 (GRIPS) and 0.8 (R1), whereas amphibolites have a(rt) of 0.95 (GRIPS and R3). A value for a(rt) of 0.80 ± 0.20 (metapelites) and 0.95 +0.05/−0.25 (amphibolites) is recommended for trace-element thermomobarometers in ilmenite-bearing, rutile-absent rocks. The dependence of Ti contents of minerals on a(rt) and the reequilibration of Ti during metamorphic reactions both deserve further exploration, and may affect application of trace-element thermobarometers

Déterminants de la structure génétique de population du tamia rayé (Tamias striatus) en milieu naturel

L'étude des patrons de dispersion et de flux génique est d'une importance indéniable puisqu'elle peut fortement influencer le potentiel évolutif et adaptatif des populations en milieux naturels. Il est donc important d'identifier et de comprendre l'impact des éléments de l'environnement qui facilitent ou inhibent le mouvement des individus. Une approche efficace à ce niveau est celle de la génétique du paysage puisqu'elle permet d'utiliser une combinaison de données spatiales et génétiques afin d'identifier les caractéristiques du paysage qui ont contribué à la formation du patron de structure génétique observé. L'objectif de ce projet était de caractériser les déterminants de la structure génétique observée à différentes échelles chez le tamia rayé (Tamias striatus) sur une aire d'étude hétérogène dans le Sud du Québec et de l'Ontario, Canada. Au niveau des déterminants géographiques de la structure génétique, j'ai détecté des barrières au flux génique reliées à des éléments du paysage, notamment le fleuve St. Laurent à grande échelle et la distance géographique à petite échelle. J'ai aussi détecté des patrons de structuration génétique différents pour les mâles et les femelles suggérant une dispersion biaisée par le sexe en faveur des mâles à toutes les échelles considérées. En conclusion, mes résultats illustrent l'importance de considérer simultanément les éléments du paysage et la distance géographique comme déterminants du patron de structure génétique, de prendre en considération l'échelle à laquelle agit chacun des déterminants et d'utiliser les mesures appropriées au plan d'échantillonnage pour la détection de dispersion biaisée par le sexe

Measuring the effects of α1 -antitrypsin polymerisation on the structure and biophysical properties of the endoplasmic reticulum.

An important function of the endoplasmic reticulum (ER) is to serve as a site of secretory protein folding. When the accumulation of misfolded proteins threatens to disturb luminal homoeostasis, the cell is said to experience ER stress. By contrast, the accumulation of well-folded proteins inside the ER leads to a distinct form of strain called ER overload. The serpins comprise a large family of proteins whose folding has been studied in great detail. Some mutant serpins misfold to cause ER stress, whereas others fold but then polymerise to cause ER overload. We discuss recent advances in the use of dynamic fluorescence imaging to study these phenomena. We also discuss a new technique that we recently published, rotor-based organelle viscosity imaging (ROVI), which promises to shed more light on the biophysical features of ER stress and ER overload
