Following basal stem rot in young oil palm plantings

The PCR primer GanET has previously been shown to be suitable for the specific amplification of DNA from Ganoderma boninense. A DNA extraction and PCR method has been developed that allows for the amplification of the G. boninense DNA from environmental samples of oil palm tissue. The GanET primer reaction was used in conjunction with a palm-sampling programme to investigate the possible infection of young palms through cut frond base surfaces. Ganoderma DNA was detected in frond base material at a greater frequency than would be expected by comparison with current infection levels. Comparisons are made between the height of the frond base infected, the number of frond bases infected, and subsequent development of basal stem rot. The preliminary results suggest that the development of basal stem rot may be more likely to occur when young lower frond bases are infected

Harvesting Lithium: water, brine and the industrial dynamics of production in the Salar de Atacama

Geographical research on lithium and other renewable energy materials explores the geopolitical dimensions of resource supply and the 'new geographies' associated with an expanding resource frontier. The material characteristics and environmental conditions of lithium production, however, are largely overlooked in this perspective. In the context of a global speculative boom for lithium linked to its growing role in energy storage, this paper adopts a grounded, exploratory approach to investigate the dynamics of production and resource management at one of the world's most significant sources of lithium: the brine deposits of the Atacama Salt Flat/Salar de Atacama in northern Chile. We show how lithium production from brine has a distinctive 'eco-regulatory' character as it involves managing a series of hydrogeological conditions and physical processes that are largely external to capital. The paper highlights the infrastructures (pumps, pipes, ponds) associated with the harvesting of lithium from brine and examines how production on the salar generates a series of ecological contradictions (notably around water depletion) with potential to disrupt accumulation. We also examine the multiple flexibilities afforded by the eco- regulatory character of production, and show how these enable lithium producers to adapt fixed infrastructures to dynamic political economic conditions. By focusing on both contradictions and flexibilities of lithium production, the paper draws attention to trajectories of capitalisation in the lithium value chain and their environmental consequences; and considers the political-economic incentives shaping further capitalisation. The paper concludes by considering the implications of this exploratory case study for critical resource geography

Technical assistance, neo-colonialism or mutual trade? The experience of an Anglo/Ukrainian/Russian social work practice learning project

Since the collapse of the Soviet Union there has been a steady stream of Western consultants ready to work in Eastern Europe and Russia and share professional and academic expertise and experience. Social work, unknown as a discrete discipline or profession in the Soviet Union, has been a growth area with funding from a variety of sources to help promote East-West partnerships.Social work theory and practice emphasises critical appraisal of policy and embraces issues of power, discrimination and oppression. Social work educators should therefore be especially alert to the complex ethical questions which these kinds of collaborations raise, and adept at finding practical solutions or workable compromises. This article explores these ethical and political issues with reference to a project to develop social work practice learning in a Russian oblast' (region). The project was an ambitious partnership of British, Ukrainian and Russian educators, involving numerous Russian social work and related agencies, and four Russian universities and colleges in one oblast'. The authors use a series of vignettes to help the reader achieve insights into these East-West transactions. The article concludes with a discussion of different interpretations of these dealings, using three prisms: technical assistance, neo-colonialism and mutual trade

An assessment of construction labour productivity in Malaysia

The construction industry is one of major strategic importance. Its level of productivity has a significant effect on national economic growth. The analysis of published census/biannual surveys of construction by the Department of Statistics of Malaysia shows that Malaysia managed to achieve construction labour productivity growth between 1996 and 2005 despite increases in cost per employee. The decrease in unit labour costs is attributed to the value added improvement per worker through the increase in capital intensity. The marginal decline in capital productivity is due to the gestation period and the overcapacity of the industry. The civil engineering sub-sector recorded the highest labour productivity and is the most labour competitive in terms of unit labour cost and added value per labour cost. The residential sub-sectors recorded greatest change in the productivity indicators between 1996 and 2005

Interaction of the solar wind with Venus

Two topics related to the interaction of the solar wind with Venus are considered. First, a short review of the experimental evidence with particular attention to plasma measurements carried out on Mariner-5 and Mariner-10 is given. Secondly, the results of some recent theoretical work on the interaction of the solar wind with the ionosphere of Venus are summarized

High-speed, energy-resolved, STJ observations of the AM Her system V2301 Oph

We present high time-resolution optical energy-resolved photometry of the eclipsing cataclysmic variable V2301 Oph made using the ESA S-Cam detector, an array of photon counting super-conducting tunnel junction (STJ) devices with intrinsic energy resolution. Three eclipses were observed, revealing considerable variation in the eclipse shape, particularly during ingress. The eclipse shape is shown to be understood in terms of AM Her accretion via a bright stream, with very little contribution from the white dwarf photosphere and/or hotspot. About two thirds of the eclipsed light arises in the threading region. Variation in the extent of the threading region can account for most of the variations observed between cycles. Spectral fits to the data reveal a 10,000K blackbody continuum with strong, time-varying emission lines of hydrogen and helium. This is the first time that stellar emission lines have been detected in the optical band using a non-dispersive photon-counting system.Comment: Accepted A&

Problematizing Choice: Responsible consumers and sceptical citizens

About the book: Governance, Consumers and Citizens is the first book to bring together a study of governance with consumption, examining the changing place of the consumer as citizen in recent trends in governance, the tensions between competing ideas and practices of consumerism and the active role consumers play in the construction and practice of governance. Radically pushing forward the debate on consumers and governance, this collection outlines new conceptions and posits new policy agendas. Bringing together international experts from political science, history, geography, social policy and media studies, this study shows how governance and consumption are intertwined in crucial aspects of public policy and contemporary politics

Mirroring the Zeitgeist: An Analysis of CSR Policies in the UK’s Food, Soft Drink and Packaging Industries

Purpose The purpose of this paper is to explore changes in corporate social responsibility (CSR) policies in food, soft drinks and packaging industries to capture changes in CSR implementation given increased environmental activism. The paper takes an exploratory approach in reviewing CSR policy changes to explore to what extent companies change CSR policies with increased environmentalism. Design/methodology/approach A comparative website analysis was used to analyse CSR policies of companies in the food, soft drinks and packaging industries in the UK. The companies were selected for the analysis based on their annual turnover and 23 companies were analysed (seven for the soft drinks industry, eight for the food industry and eight for packaging industry). Five interviews were conducted with packaging and retail professionals, and the findings were analysed by using thematic analysis, which captured trends in responses. Findings The findings show that companies are implementing and communicating CSR policies heavily focussed on reducing the environmental impact of their work and matching social debates on human rights, with which traditional CSR policies (corporate governance, supporting local communities and consultation with stakeholders) are fading away. Instead, companies have shifted attention towards the gender pay gap, modern slavery and extensive environmentalism. The interviews with packaging professionals and CSR managers from the retail industry show that the packaging industry designs CSR policies in line with requests from supermarkets, which are, in turn, influenced by consumer activism. Practical implications This paper shows the circular relationship between media coverage, consumer activism, which comes as a result, and the impact and changes this brings to the industry. To avoid reputation damage, companies should closely follow media debates to pre-empty consumer criticism and activism. Social implications The findings show that companies are “mirroring the zeitgast” and going with trends to meet consumer expectations, which brings into question the sincerity of CSR policies and revives the criticism of capitalism and raises a question whether CSR is used by companies as a smokescreen that on the outset makes a difference to the society but keeps status quo intact. Originality/value The paper provides an insight into CSR implementation of three industries that faced heavy criticism from campaigners and the general public for their environmental impact. The paper shows how the CSR policy shifted to match this expectation and thus provides a good ground for studying the evolution of CSR using a case study from three selected industries

Silver Diamine Fluoride: Transforming Community Dental Caries Program.

INTRODUCTION: Untreated dental caries is the most frequent childhood chronic disease worldwide. Silver diamine fluoride (SDF) offers a safe and effective alternative treatment, especially for children. OBJECTIVE: To inform the dental community about the efficacy of SDF in community dental caries programs and to advocate for its use as an affordable and equitable approach to promote health and well-being within the dental setting. METHODS: A summary of the literature shared during a webinar about the use and efficacy of SDF in community dental programs hosted by the Oral Health Working Group of the World Federation of Public Health Associations RESULTS: Based on the traditional "drill-and-fill" approach, the current treatment for severe caries is associated with pain, fear, and poor oral health outcomes in later life. Innovative approaches to prevent and control caries are needed. SDF offers an alternative treatment option for caries. It is a practical, affordable, and acceptable option for caries treatment, eliminating the need for general anaesthetic in young children, and improving long-term oral health outcomes. CONCLUSION: SDF can improve oral health outcomes for community members, especially for individuals from low-socioeconomic settings
