What Can We Learn from Independent Family-Owned Local Media Groups?
Local media organisations were traditionally founded as guardians of their local communities, embedded in the towns in which they published. Historically, within the United Kingdom, local newspapers were independent family-owned businesses. These newspapers were an integral part of the local community, offering opinion and debate on matters of local importance, pulling together communities, defined geographically or by municipal administrative bo…
Defining and Implementing Value-Based Health Care
Value in health care is the measured improvement in a person’s health outcomes for the cost of achieving that improvement. While some descriptions conflate value-based health care and cost reduction, quality improvement, or patient satisfaction, those efforts—while important—are not the same as value, which focuses primarily on improving patient health outcomes. A decade of research into organizations that have achieved better outcomes while ofte…
Experiencing Local News Online
This article explores how audiences experience local news online. It discusses the findings of an empirical study that examined why audiences consumed local news online, what sources they were most likely to access, how important distributing platforms were in local news use, and what users understood by local news. \n \nThe research had a qualitative design applying diaries as its main method collecting data in the South-East of England in 2016 …
Variation in beliefs about ‘fracking’ between the UK and US
In decision-making on the politically-contentious issue of unconventional gas development, the UK Government and European Commission are attempting to learn from the US experience. Although economic, environmental, and health impacts and regulatory contexts have been compared cross-nationally, public perceptions and their antecedents have not. We conducted similar online panel surveys of national samples of UK and US residents simultaneously in S…

Educational Mobility and the Gendered Geography of Cultural Capital
International student mobility from East to West has grown rapidly as the middle classes have sought to reproduce their advantage in the context of changing socioeconomic circumstances. Existing research shows that middle-class students and their parents are increasingly using overseas educational qualifications-an institutionalised form of cultural capital-to ensure that they stand out in the competition for lucrative employment. This paper make…
Dumping on the Poor
This paper investigates the 'ecological distribution' and associated environmental injustices of Accra's growing domestic-waste burden and examines how inequalities in the spatial distribution of waste-collection services and waste-disposal sites reflect the uneven distribution of power and wealth within Ghanaian society. Particular emphasis is placed on inequalities in municipal service provision associated with Accra's integration within the gl…
"China's "Dash for Gas
Two UK-based researchers examine the significant recent growth in China's demand for natural gas, a fuel not long ago considered of marginal importance but now viewed as critical for the country's future economic growth. Based on a range of databases as well as industry and media reports, the authors demonstrate how rapid demand growth since 2005 has transformed China from a minor, self-sufficient gas producer to a major buyer on international ga…
Estrategias para el control del agua en Oaxaca colonial
El resultado del proceso colonizador sobre la propiedad y el uso del agua en el valle central de Oaxaca culminó, como en otros sitios de México, en el acaparamiento de los beneficios del líquido vital por parte de los colonos españoles. Si las prerrogativas emanadas de la conquista permitieron que la mitad de la tierra quedara en manos de los antiguos cacicazgos y del marqués del Valle, restringiendo la ocupación de la tierra a los colonos y enco…
Household Incomes in Central Asia
Two European geographers present the findings of a sizeable survey (n = 7,515) providing a detailed geographical analysis of household incomes and reliance on personal subsidiary garden plots across Kazakhstan. The authors focus on assessing the extent to which Kazakhstan's rising GDP during the post-Soviet period has coincided with an increase in the general population's personal income and ability to secure adequate food supplies for personal c…
The Impact of Global Economic Crisis on Remittances in the Commonwealth of Independent States
Two European geographers and an economist analyze the impact of the 2008-2009 global economic recession on remittances in the Commonwealth of Independent States. Drawing on balance-of-payments data as well as information on money transfers to and from the region, they detail the annual growth of remittances since 2001, illustrating the growing importance of this income stream to a number of countries in the region. Using quarterly data, they then…
From Geo-Strategy to Geo-Economics
In this paper we examine the changing perception of Central Asia and the Caucasus to Imperial Britain from the mid nineteenth to the mid twentieth centuries and consider the importance of Mackinder's 1904 paper ‘The Geographical Pivot of History’ to this process. In it we argue that Central Asia and the Caucasus are seen first as an important buffer zone essential to keeping the Russia aggressors at bay and ensuring Britain's continued dominance …
Experiment and innovation
The city of al-Raqqa in north central Syria rivalled early Baghdad in scale, and was briefly during the 'Abbasid caliphate the imperial capital of an empire stretching from North Africa to Central Asia. Now largely levelled the multifaceted Islamic cityscape is revealed by aerial and satellite imagery. It is at this site that the evidence of innovative Islamic industries has been revealed by excavations undertaken by the Raqqa Ancient Industry pr…

Corona Remotely-Sensed Imagery in Dryland Archaeology
Satellite remote sensing has seen some use in archaeological research, although its effectiveness has been restricted by the low spatial resolution and the high cost of available imagery. In 1995 the United States declassified 860,000 high-resolution Corona satellite photographs, acquired for intelligence purposes between 1960 and 1972. Corona offers global coverage with an emphasis on areas of strategic significance to the United States. The ima…

Great game or Grubby game? the struggle for control of the Caspian
In this article I examine the way in which resource conflict in the Caspian Sea Basin has become entwined in the development of geopolitical thought and ideas since the late nineteenth century. I argue that Mackinder's inclusion of the Caspian in his original pivot was significant and that because of its considerable strategic importance control of the region was seen as crucial to all sides in both the First World War and the Second World War. T…
The dynamics and characteristics of aeolian dust in dryland Central Asia
The drying up of the Aral Sea has been described as one of the most staggering environmental disasters of the twentieth century. Over the last 40 years over 36 000 km2 of the former seabed have been exposed, creating a potentially significant aeolian dust source. It is widely believed, but little researched, that increased dust storm activity in the region has had a major impact on human health. In this paper we report the findings of a study int…
Wet Conditions during the Last Glaciation in the Chihuahuan Desert, Alta Babicora Basin, Mexico
A 467-cm core (B94/3) from the Alta Babicora basin in the Chihuahuan Desert, northern Mexico (29°N, 108°W), documents lake-level and climate changes over the past ca. 65,000 yr. Chronological control is provided by four accelerator mass spectrometry 14 C dates and five U-series dates on diatom silica. The core has been analyzed for magnetic susceptibility, loss-on-ignition, carbonate content, sediment chemistry and mineralogy, and pollen and diat…

Irrigation and Water Management in Turkmenistan
FOR THE FORMER SOVIET REPUBLIC OF TURKMENISTAN agriculture is the single most important economic activity in that more than 40% of the population is directly in its employ. For a greater number of people it represents a major secondary income source, which in the economic crisis of the post-independence period has assumed even greater significance. With agriculture in Turkmenistan being almost totally dependent on irrigation, access to water is e…
Degradation, Drought, and Dissent
Environmental degradation of the central Mexican highlands has traditionally been attributed to colonial land-use change, specifically the introduction of livestock and the use of the plow. Some investigations, however, suggest that the Spanish encountered an already modified or degraded landscape in many locations, and as such, the environmental impacts of Spanish colonization have been overstated. In this paper, we present evidence as to the po…
Development and Environmental Significance of an Eolian Sand Ramp of Last-Glacial Age, Central Iran
A 25-m-thick section of mostly eolian sediment is exposed in the stream-cut flank of a sand ramp accumulated in a mountain saddle near Ardakan playa, central Iran. The well-sorted eolian sediments of the ramp contain talus beds and incipient paleosols. Morphology and bedding structures imply that southeasterly winds were primarily responsible for deposition of the eolian sand. Optical dating shows that the sand was deposited near the last glacial…
Conflicts Over Water in 'The Little Drought Age' in Central Mexico
Mexico represents one of the most climatically sensitive regions of the world. Over the Colonial period, prolonged drought episodes had severe impacts on all sectors of society, particularly indigenous rural populations. This paper employs a variety of colonial historical records to document the nature and extent of these impacts within the context of prevailing social, political and economic conditions. It is clear that access to water has long …

Reconstructing the climate of Mexico from historical records
There is a growing number of studies that use historical sources to reconstruct recent environmental change. In Mexico there are abundant sources of information that can be used to determine variations in the climate over the historical period. In this paper we draw together information from a variety of primary and secondary historical sources to reconstruct fluctuations in the climate of central Mexico over the last 600 years. The Aztecs are be…
