Corporate Geographies Of Transnational Tourism Companies

The central aim of this thesis is to contribute to the knowledge of restructuring processes in the tourism production system and to analyse the implications of socio-spatial practices and strategies of transnational, integrated tourism corporations in light of the ‘new’ economic geography. It is based on the cultural turn in the discipline of geography and thus recognises that cultural and social processes are an integral part of economic systems and contribute to shaping the economic landscape. The thesis specifically investigates the corporate geographies of tourism corporations and their relationship with territorial spaces. Restructuring processes are examined demonstrating that the European tourism production system has experienced significant structural changes during a wave of large- and small-scale mergers and acquisitions resulting in the emergence of tourism corporations with a wide and uneven geographical expansion. An analysis of shareholdings of individual tourism corporations also highlights significant variation in the level of internationalisation and expansion. Socio-economic approaches to the firm form the theoretical foundations for analysing the relationship between tourism corporations and place via the concept of embeddedness within networks of social relations using examples from Mallorca, Spain. A combination of questionnaire survey and semistructured interviews was employed in order to map the structural and qualitative attributes of intra-, inter- and extra-firm networks. Encountered difficulties, however, resulted in a more exploratory approach to the application of theoretical concepts and required added reliance on secondary sources and informal discussion with experts. Historical connection between tour operators and Mallorcan hotel companies has provided a firm basis for close cooperation with mutual benefit and has allowed Mallorcan hotel companies to internationalise in conjunction with the internationalisation of tourist flows. The examination of regulatory networks has revealed a complex and dynamic mosaic of scales at subnational, national and supranational levels, which govern and shape the activities of tourism corporations

Controls on the seasonal exchange of CH3Br in temperate peatlands

Measurements of CH3Br exchange at two New Hampshire peatlands (Sallie\u27s Fen and Angie\u27s Bog) indicate that net flux from these ecosystems is the sum of competing production and consumption processes. Net CH3Br fluxes were highly variable and ranged from net emission to net uptake between locations within a single peatland. At Sallie\u27s Fen, net CH3Br flux exhibited positive correlations with peat temperature and air temperature during all seasons sampled, but these relationships were not observed at Angie\u27s Bog where flux varied according to microtopography. The major CH3Br production process at Sallie\u27s Fen appeared dependent on aerobic conditions within the peat, while CH3Br production at Angie\u27s Bog was favored by anaerobic conditions. There was evidence of aerobic microbial consumption of CH3Br within the peat at both sites. In a vegetation removal experiment conducted at Sallie\u27s Fen with dynamic chambers, all collars exhibited net consumption of CH3Br. Net CH3Br flux had a negative correlation with surface temperature and a positive correlation with water level in collars with all vegetation clipped consistent with aerobic microbial consumption. Vegetated collars showed positive correlations between net CH3Br flux and air temperature. A positive correlation between net CH3Br flux and surface temperature was also observed in collars in which all vegetation except Sphagnum spp. were clipped. These correlations are consistent with seasonal relationships observed in 1998, 1999, and 2000 and suggest that plants and/or fungi are possible sources of CH3Br in peatlands. Estimates of production and consumption made on two occasions at Sallie\u27s Fen suggest that peatlands have lower rates of CH3Br consumption compared to upland ecosystems, but a close balance between production and consumption rates may allow these wetlands to act as either a net source or sink for this gas

Production of methyl bromide in a temperate forest soil

Field enclosure measurements of a temperate forest soil show net uptake of ambient methyl bromide (CH3Br), an important trace gas in both tropospheric and stratospheric ozone cycling. The net flux for 1999 was estimated to be −168 ± 72 μg CH3Br m−2 (negative indicates loss from the atmosphere). Individual enclosure flux measurements ranged from −4.0 to +3.3 μg CH3Br m−2 d−1. Soil consumption of CH3Br was estimated from laboratory soil incubations. Production of CH3Br was calculated as the difference between net flux and predicted consumption. Fungi could be responsible for the production of CH3Br in this temperate forest soil

Climate change and crop exposure to adverse weather: changes to frost risk and grapevine flowering conditions

Open Access Article© 2015 Mosedale et al.The cultivation of grapevines in the UK and many other cool climate regions is expected to benefit from the higher growing season temperatures predicted under future climate scenarios. Yet the effects of climate change on the risk of adverse weather conditions or events at key stages of crop development are not always captured by aggregated measures of seasonal or yearly climates, or by downscaling techniques that assume climate variability will remain unchanged under future scenarios. Using fine resolution projections of future climate scenarios for south-west England and grapevine phenology models we explore how risks to cool-climate vineyard harvests vary under future climate conditions. Results indicate that the risk of adverse conditions during flowering declines under all future climate scenarios. In contrast, the risk of late spring frosts increases under many future climate projections due to advancement in the timing of budbreak. Estimates of frost risk, however, were highly sensitive to the choice of phenology model, and future frost exposure declined when budbreak was calculated using models that included a winter chill requirement for dormancy break. The lack of robust phenological models is a major source of uncertainty concerning the impacts of future climate change on the development of cool-climate viticulture in historically marginal climatic regions.European Social FundNatural Environment Research Council (NERC

Microclima: An R package for modelling meso- and microclimate

This is the author accepted manuscript. The final version is available on open access from Wiley via the DOI in this record1.Climate is of fundamental importance to the ecology and evolution of all organisms. However, studies of climate–organism interactions usually rely on climate variables interpolated from widely‐spaced measurements or modelled at coarse resolution, whereas the conditions experienced by many organisms vary over scales from millimetres to metres. 2.To help bridge this mismatch in scale, we present models of the mechanistic processes that govern fine‐scale variation in near‐ground air temperature. The models are flexible (enabling application to a wide variety of locations and contexts), can be run using freely available data and are provided as an R package. 3.We apply a mesoclimate to the Lizard Peninsula in Cornwall to provide hourly estimates of air temperature at resolution of 100m for the period Jan‐Dec 2010. A microclimate model is then applied to a one km2 region of the Lizard Peninsula, Caerthillean Valley (49.969 ºN, 5.215 ºW), to provide hourly estimates of near‐ground air temperature at resolution of one m2 during May 2010. 4.Our models reveal substantial spatial variation in near‐ground temperatures, driven principally by variation in topography and, at the microscale, by vegetation structure. At the meso‐scale, hours of exposure to air temperatures at one m height in excess of 25 °C ranged from 23 to 158 hours, despite this temperature never being recorded by the weather station within the study area during the study period. At the micro‐scale, steep south‐facing slopes with minimal vegetation cover experienced temperatures in excess of 40 °C. 5.The microclima package is flexible and efficient and provides an accurate means of modelling fine‐scale variation in temperature. We also provide functions that facilitate users to obtain and process a variety of freely available datasets needed to drive the model.This research was part-funded by the European Social Fund Project 09099NCO5 and NERC NE/P016790/

What factors influence the use of contracts in the context of NHS dental practice?:A systematic review of theory and logic model

AbstractUK NHS contracts mediate the relationship between dental and medical practitioners as independent contractors, and the state which reimburses them for their services to patients. There have been successive revisions of dental and medical contracts since the 1990s alongside a change in the levels of professional dominance and accountability. Unintended consequences of the 2006 dental contract have led to plans for further reform. We set out to identify the factors which facilitate and hinder the use of contracts in this area. Previous reviews of theory have been narrative, and based on macro-theory arising from various disciplines such as economics, sociology and political science. This paper presents a systematic review and aggregative synthesis of the theories of contracting for publicly funded health care. A logic map conveys internal pathways linking competition for contracts to opportunism. We identify that whilst practitioners' responses to contract rules is a result of micro-level bargaining clarifying patients' and providers' interests, responses are also influenced by relationships with commissioners and wider personal, professional and political networks

Young Adult Nonfiction Collection Development Practices in One Public Library System

Numerous researchers have examined the reading interests of young adults and concluded that they have a strong interest in reading nonfiction. Despite these findings, the young adult nonfiction collections in public libraries continue to be far smaller than the young adult fiction collections. This is the first study to explore this disconnect between research findings and the reality of young adult nonfiction collection development practices in public libraries. In this exploratory study, the librarians who work with young adult materials and patrons in one public library system were interviewed in an attempt to discover what issues may be keeping public libraries from developing young adult nonfiction collections large enough to meet young adults' nonfiction reading needs. The results showed a large number of obstacles that might hinder the development of young adult nonfiction collections in public libraries and suggest some ways in which those obstacles may be overcome

Climate change impacts and adaptive strategies: lessons from the grapevine

This is the author accepted manuscript. The final version is available from Wiley via the DOI in this recordThe cultivation of grapevines for winemaking, known as viticulture, is widely cited as a climate-sensitive agricultural system that has been used as an indicator of both historic and contemporary climate change. Numerous studies have questioned the viability of major viticulture regions under future climate projections. We review the methods used to study the impacts of climate change on viticulture in the light of what is known about the effects of climate and weather on the yields and quality of vineyard harvests. Many potential impacts of climate change on viticulture, particularly those associated with a change in climate variability or seasonal weather patterns, are rarely captured. Key biophysical characteristics of viticulture are often unaccounted for, including the variability of grapevine phenology and the exploitation of microclimatic niches that permit successful cultivation under suboptimal macroclimatic conditions. We consider how these same biophysical characteristics permit a variety of strategies by which viticulture can adapt to changing climatic conditions. The ability to realize these strategies, however, is affected by uneven exposure to risks across the winemaking sector, and the evolving capacity for decision-making within and across organizational boundaries. The role grape provenance plays in shaping perceptions of wine value and quality illustrates how conflicts of interest influence decisions about adaptive strategies within the industry. We conclude by considering what lessons can be taken from viticulture for studies of climate change impacts and the capacity for adaptation in other agricultural and natural systems

Extraction of ellagitannins from oak wood of model casks

Eight experimental model casks were constructed using wood from four oak trees and filled with a 12 % ethanol solution for 200 days. The concentration of ellagitannins was subsequently measured in the solutions and in the inner and outer faces of the cask wood. Only a low proportion of the total ellagitannins was extracted from the wood, and this proportion varied significantly between both different casks and between the eight ellagitannins measured. The two most abundant ellagitannins, castalagin and vescalagin, were the least easily extracted. The concentration of ellagitannins was much lower in the solutions than expected from calculations based on the difference between the inner and outer faces of the wood. This degradation of ellagitannins occurs subsequent to their extraction into solution

Contracting with General Dental Services: a mixed-methods study on factors influencing responses to contracts in English general dental practice

Background: Independent contractor status of NHS general dental practitioners (GDPs) and general medical practitioners (GMPs) has meant that both groups have commercial as well as professional identities. Their relationship with the state is governed by a NHS contract, the terms of which have been the focus of much negotiation and struggle in recent years. Previous study of dental contracting has taken a classical economics perspective, viewing practitioners’ behaviour as a fully rational search for contract loopholes. We apply institutional theory to this context for the first time, where individuals’ behaviour is understood as being influenced by wider institutional forces such as growing consumer demands, commercial pressures and challenges to medical professionalism. Practitioners hold values and beliefs, and carry out routines and practices which are consistent with the field’s institutional logics. By identifying institutional logics in the dental practice organisational field, we expose where tensions exist, helping to explain why contracting appears as a continual cycle of reform and resistance. Aims: To identify the factors which facilitate and hinder the use of contractual processes to manage and strategically develop General Dental Services, using a comparison with medical practice to highlight factors which are particular to NHS dental practice. Methods: Following a systematic review of health-care contracting theory and interviews with stakeholders, we undertook case studies of 16 dental and six medical practices. Case study data collection involved interviews, observation and documentary evidence; 120 interviews were undertaken in all. We tested and refined our findings using a questionnaire to GDPs and further interviews with commissioners. Results: We found that, for all three sets of actors (GDPs, GMPs, commissioners), multiple logics exist. These were interacting and sometimes in competition. We found an emergent logic of population health managerialism in dental practice, which is less compatible than the other dental practice logics of ownership responsibility, professional clinical values and entrepreneurialism. This was in contrast to medical practice, where we found a more ready acceptance of external accountability and notions of the delivery of ‘cost-effective’ care. Our quantitative work enabled us to refine and test our conceptualisations of dental practice logics. We identified that population health managerialism comprised both a logic of managerialism and a public goods logic, and that practitioners might be resistant to one and not the other. We also linked individual practitioners’ behaviour to wider institutional forces by showing that logics were predictive of responses to NHS dental contracts at the dental chair-side (the micro level), as well as predictive of approaches to wider contractual relationships with commissioners (the macro level) . Conclusions: Responses to contracts can be shaped by environmental forces and not just determined at the level of the individual. In NHS medical practice, goals are more closely aligned with commissioning goals than in general dental practice. The optimal contractual agreement between GDPs and commissioners, therefore, will be one which aims at the ‘satisfactory’ rather than the ‘ideal’; and a ‘successful’ NHS dental contract is likely to be one where neither party promotes its self-interest above the other. Future work on opportunism in health care should widen its focus beyond the self-interest of providers and look at the contribution of contextual factors such as the relationship between the government and professional bodies, the role of the media, and providers’ social and professional networks.
