Climate and visitation to Utah's ‘Mighty 5’ national parks

ABSTRACT

The relationship between climate and visitation to managed natural areas has been analyzed at a variety of different spatial scales. We expand upon our existing knowledge on this topic by: (1) determining how a wide range of climate variables affect visitation across a regional tourism system; and (2) identifying which variables affect visitation system-wide and which variables only affect visitation at specific parks. Our analysis focuses on five national parks located in southern Utah (USA) commonly referred to as ‘the Mighty 5’. We found monthly average daily maximum temperatures were the best predictor of system-wide visitation, suggesting average daily maximum temperatures play a more direct role in tourists’ travel decisions relative to other climate variables, including other derivations of temperature. We also found declines in monthly park visitation for three parks (Arches, Canyonlands, and Capitol Reef) once average daily maximum temperatures exceed 25 C. For Bryce Canyon and Zion however, monthly visitation continued to increase well above this threshold. The geophysical characteristics of these parks appear to mediate the relationship between average daily maximum temperature and visitation. The commonly found ‘inverted U-shape’ relationship between temperature and visitation should not be seen as a universal maxim. We also found precipitation to be a poor predictor of system-wide visitation, but a significant factor shaping the travel decisions of visitors to Bryce Canyon, the only park to offer snow-based outdoor recreation opportunities. Future research should not disregard the possibility of precipitation being a significant factor shaping visitors’ travel decisions. By conducting our analyses at two distinct scales, we have found there is a difference between the individual climate variables that are regionally-significant drivers of visitation and those that are locally-significant drivers of visitation. Scale matters in analyses of the relationship between climate and visitation.     

Untangling Palimpsest Landscapes in Conflict Zones: A “Remote Survey” in Spin Boldak,Southeast Afghanistan

Remote survey using high-resolution satellite images allows archaeologists to study ancient landscapes in regions made inaccessible by ongoing conflict as well as in regions located between zones of better archaeological knowledge. Such studies frequently suffer from a lack of chronological information. This paper presents the results of remote landscape survey in the territory of Spin Boldak (“white desert”) in Kandahar province, Afghanistan, and methodological efforts to detangle the chronology of a landscape made inaccessible by conflict. The studied region crosscuts several environmental zones (desert, alluvial plain, river, and hills) and lies within an important corridor of movement toward mountain passes on the Afghanistan–Pakistan border. Morphological comparisons of surveyed sites to better-documented examples and synthesis of data from a variety of sources allow us to draw chronological and taphonomic conclusions about three types of documented sites: fortified enclosures, caravanserai, and mobile pastoral camps. These methods provide time depth to our understanding of the remotely-mapped landscape and allow us to consider Spin Boldak as a place shaped by local and regional historical processes rather than merely as a timeless thoroughfare between more intensively inhabited locales.

A Woman's Place in the Crab Processing Industry of Eastern Carolina

Traditionally, most of the pickers used in the crab processing industry of rural Eastern Carolina have been women from the local area, both black and white, while the managerial staff has comprised white women related through kinship to the white, male crab house owners. In recent years, however, this recruitment strategy has changed. Following the lead of the regional poultry industry, the crab houses are now bringing in Mexican workers under the H2-B visa program. Unlike many of the Mexican migrant workers coming into the USA, the crab labor force is made up of women, about half of whom are married with children. This article provides a case study of the ensuing dual labor structure within the crab processing industry. Utilizing in-depth interviews with the employers and employees of the Luther Lewis and Son crab house, the authors ask: What are the contours of inclusiveness and exclusiveness within and without the crab house?     

Imperial Geography and the Medieval Peutinger Map

The Peutinger map is an extraordinary world map drawn c.1200 and long considered a copy of a Roman road map made for late antique travellers. This paper presents arguments against these assumptions and concludes that the lost original was more likely to be a Carolingian display map. Ninth‐century scribes had the expertise and resources necessary for creating an antiquarian work based on Roman itinerary lists, while Carolingian rulers had ample motivation for commissioning a map to display their Roman imperial ambitions.     

Going West and Going Out: discourses,migrants, and models in Chinese development

Abstract

In 1999 China announced the launching of the Open up the West campaign, sometimes called “Going West,” to help western China finally catch up to the much wealthier eastern, coastal areas after several decades of lagging behind. The same year, China also announced a “Going Out” strategy to encourage Chinese investment abroad. The 15 years since then have witnessed dramatic Chinese government investment in various development activities in western regions of China, as well as around the world. Though rarely considered together, we argue that there are significant parallels in development discourse, the centrality of physical infrastructure, the characteristics of Chinese labor migration and the nature of migrant-local relations, and the application of “models from elsewhere” in Going West and Going Out. Considering these parallels can help shed light on Chinese development discourse and practice, as China becomes increasingly important in the field of development once dominated by Western countries. Finally, we also consider direct connections and convergences between the two strategies in China’s neighboring countries of Asia and in the One Belt One Road initiative.     

Regional Seismic Risk Assessment of Bridge Network in Charleston,South Carolina

This article presents the results of a seismic risk assessment of the bridge network in Charleston, South Carolina and the surrounding counties to support emergency planning efforts, and for prioritization of bridge retrofit. This study includes an inventory analysis of the approximately 375 bridges in the Charleston area, and convolution of the seismic hazard with fragility curves analytically derived for classes of bridges common to this part of the country. State-of-the-art bridge fragility curves and replacement cost estimates based on region-specific data are used to obtain economic loss estimates. The distribution of potential bridge damage and economic losses are evaluated for several scenario events in order to aid in the identification of emergency routes and assess areas for investment in retrofit. This article also evaluates the effect of uncertainty on the resulting predicted economic losses. The findings reveal that while the risk assessment is very sensitive to both the assumed fragility curves and damage ratios, the estimate of total expected economic losses is more sensitive to the vast differences in damage ratio models considered.
