Too late to buy a home? School redistricting and the timing and extent of capitalization

In the past 50 years, a voluminous literature estimating the value of schools through capitalization in home prices has emerged. Prior research has identified capitalization using a variety of approaches including discontinuities caused by boundaries. Here, we use changes in school boundaries and the opening of a new school in Fayette County (Lexington), Kentucky to identify this capitalization. Critical to properly estimating the effect of redistricting is to account for when information on redistricting is available. We treat the information about the effects of zoning as occurring in three stages: announcement of the intent to open the new high school and redistricting, approval of the specific redistricting plan (map), and implementation (opening of the new high school and actual changes in boundaries). We find significant changes in values for homes redistricted from lower-performing schools and we find that this capitalization occurs well before implementation of the redistricting. As we show, failure to account for capitalization occurring before implementation will attenuate and even change the sign of capitalization.     

Obsidian hydration dating by infrared spectroscopy: method and calibration

Low temperature (90–190 °C) hydrothermal experiments have been conducted on seven obsidians where composition of the glass varies significantly in the concentration of structural water within the unhydrated bulk material. Infrared transmission spectroscopy was used to track the diffusion of molecular water into the glass surface as a function of time and temperature. Long-term (60–360 days) hydration sequences at 90 °C show a t^0.6 time dependence for the mass uptake of molecular water that forms the hydration layer. The structural water concentration of the unhydrated bulk obsidian is highly correlated with the pre-exponential and activation energy and may be used to estimate the Arrhenius constants. In addition, secondary ion mass spectrometry (SIMS) hydrogen profiling of Napa Glass Mountain obsidian hydrated at 90 °C reveals that the early stages of diffusion exhibit a dynamic behavior that includes a fluctuating hydrogen concentration and a changing diffusion coefficient that slows with time.     

MEASURING THE IMPACT OF SEA‐LEVEL RISE ON COASTAL REAL ESTATE: A HEDONIC PROPERTY MODEL APPROACH*

ABSTRACT This study estimates the impact of sea‐level rise on coastal real estate in North Carolina using a unique integration of geospatial and hedonic property data. With rates of sea‐level rise approximately double the global average, North Carolina has one of the most vulnerable coastlines in the United States. A range of modest sea‐level rise scenarios based on the IPCC Fourth Assessment Report projections (2007) are considered for four counties of North Carolina—New Hanover, Dare, Carteret, and Bertie—which represent a cross‐section of the state's coastline in geographical distribution and economic development. High‐resolution topographic LIDAR (light detection and ranging) data are used to provide accurate inundation maps for the properties that will be at risk under six different sea‐level rise scenarios. A simulation approach based on spatial hedonic models is used to provide consistent estimates of the property value losses. Considering just four coastal counties in North Carolina, the value of residential property loss without discounting in 2030 (2080) is estimated to be about $179 ($526) million for the mid‐range sea‐level rise scenarios. Low‐lying and heavily developed areas in the northern coastline are comparatively more vulnerable to the effect of sea‐level rise than the other areas.     

Measuring Paleoindian range mobility and land-use in the Great Lakes/Northeast

Distance and direction to source data were compiled on the main toolstones employed at 83 Paleoindian sites with concave-based points (ca. 11,000–10,000 B.P.) from across the recently deglaciated Great Lake-Northeastern area of North America. These data were used in order to more rigorously evaluate several much debated ideas about annual range mobility scale and land use patterns and how they changed over time as these groups colonized and settled into the area. Movements are significantly biased to north–south axes, strongly suggesting these represent mainly seasonal moves and procurement of toolstones during regular travels rather than by specialized task groups. Means of comparing the scale of range mobility to ethnographic norms are explored and the results clearly show that these groups, especially the earliest occupants, had large annual range mobility scales and distinctive patterns of land use that are rarely seen or approached historically. They had to have been intensively targeting widely spaced but relatively abundant resources on the landscape. The only ethnographic groups who come close to such patterns historically were all caribou hunters, a perspective consistent with the idea these groups regularly exploited that resource. As long suggested, these land use patterns are probably related to the colonization of new lands in which there were little or no existing populations.     

Geochemical indicators of preservation status and site deterioration at Star Carr

This paper presents the results of a project aimed at investigating the deterioration of organic remains at the Mesolithic site of Star Carr. Analyses of pH, Electrical Conductivity and Redox Potential are reported from borehole transects across the unexcavated part of the site. A comparison of field and laboratory measurements is made, leading to the characterisation of different preservation zones and identification of ‘vulnerable’ sediments at the site. These data are augmented by geochemical analyses of contemporary borehole sequences and adjacent historic monoliths. Analysis of surface water and groundwater has also been undertaken to assist in the interpretation of the site hydrology and geochemistry. The relationship between ‘natural’ geology and preservation potential, and the evidence for a ‘halo’ preservation effect in virgin sediments adjacent to previous archaeology trenches is investigated.     

The state of climate change adaptation in Canada's protected areas sector

L’adaptation aux changements climatiques dans les réseaux d’aires protégées du Canada : état des lieux La Commission mondiale des aires protégées a récemment laissé entendre que les actions en faveur de la conservation sont vouées à l’échec, à moins que ces dernières tiennent compte des changements climatiques. Pour ce faire, les organismes chargés des aires protégées doivent dès maintenant s’assurer de l’intégration des changements climatiques dans les politiques, les cadres de planification et les modes de gestion. Le présent article rend compte des résultats d’une enquête réalisée conjointement par l’Université de Waterloo et le Conseil canadien des aires écologiques. Celle‐ci vise à dresser un état des lieux sur l’adaptation aux changements climatiques dans tout le réseau d’aires protégées du Canada qui relève du palier fédéral, provincial ou territorial. Il se dégage de l’analyse plusieurs constats importants. Tout d’abord, sur l’ensemble des organismes chargés des aires protégées que nous avons interrogés, les trois quarts ont déclaré que les changements climatiques ont déjà des effets visibles sur leur réseau d’aires protégées. Ensuite, 94 pour cent des participants à l’enquête estiment qu’au cours des vingt‐cinq prochaines années, l’enjeu des changements climatiques sera au c?ur de la politique et de la planification des aires protégées. Finalement, malgré la perception voulant que les changements climatiques exercent une pression croissante, la portée des mesures politiques, de planification, de gestion ou de recherche mises de l’avant par la plupart des organismes jusqu’à maintenant demeure limitée. Si 91 pour cent des organismes indiquent ne pas disposer des capacités nécessaires en ce moment pour réagir de façon optimale aux changements climatiques, l’enquête a permis de mettre en évidence un écart significatif entre la perception de la gravité des changements climatiques et la capacité des organismes chargés des aires protégées de s’adapter. La faiblesse du financement, une capacité d’action limitée, et un manque de compréhension des changements climatiques et de leurs répercussions réelles ou potentielles comptent parmi les difficultés auxquelles sont confrontés les organismes canadiens chargés des aires protégées. Il est impératif de les surmonter afin que ces organismes puissent exercer leurs mandats et être en mesure d’assumer leurs responsabilités concernant la protection et la biodiversité des aires, par exemple, la protection de l’intégrité du patrimoine naturel au Canada dans un contexte de changements climatiques accélérés.     

The Engraver,The Chandler and the Trades Unionist: Reflections on the Grassroots Reading of Scripture*

Abstract

Politics and religion often use the same kind of language to achieve their ‘missionary’ ends, hut such language is stripped of its meaning unless it is related to ultimate, rather than short-term, purpose. This is demonstrated by notions of election, the place of the prophet and the effects of the ‘powers’ in global society. The energy and creativity of responding to an ultimate vision is undermined in both political and relgious affairs by institutionalization. The fact that this takes place asks us to reconsider what it really means, in both religion and politics, to ‘reach out to people’ and what purpose such outreach serves.     

Situating banal nationalism,the culture wars,and civil religion: governing localized geographies of national identity in Indiana

Various material forms of national identity have become ubiquitous features of the post-9/11 American cultural landscape. This research specifically examines the ‘In God We Trust’ (IGWT) license plate in the state of Indiana as a material expression and territorialized form of national identity. While conceptually anchored in banal nationalism research, exploring the spatial patterns of adoption or non-adoption of IGWT license plates by Indiana residents is only possible through situating this research through the mediating lens of the culture wars and civil religion. Although the IGWT license plate project legislatively materialized through the localized spatial networks of non-state actors in the context of a new and conservative state–citizen relationship firmly anchored in the culture wars, adoption behavior is also mediated through the much broader influence of civil religion. We conduct a quantitative analysis to determine license plate spatial distribution by county, but more importantly to explore the sociodemographic dimensions of IGWT license plate adoption and non-adoption. While our results generally mirror the sociodemographic findings of social issue-based electoral geography, the imbrication of banal nationalism, the culture wars, and civil religion as materially expressed by the IGWT license plate yields an ideologically different and broader dynamic when compared to culture wars defined by national identity.
