Fisheries - Abstract
© 2018 The coastal and marine environment is often managed according to the principles of sustainable development, which include environmental, economic, and social dimensions. While each are equally important, social sustainability receives a lower priority in both policy and research. Methodologies for assessing social sustainability are less developed than for environmental and economic sustainability, and there is a lack of data on the social aspects of sustainable development (such as social equity), which constitutes a barrier to understanding social considerations and integrating them into natural resource management. This paper explores a threat and risk assessment to the marine estate in New South Wales, Australia, which identified and categorised both the benefits that communities gain from the marine estate and the threats to those benefits. A broad range of benefits were identified including participation (e.g., socialising and sense of community), enjoyment (e.g., enjoying the biodiversity and beauty), cultural heritage and use, intrinsic and bequest values, the viability of businesses, and direct economic values. Threats to community benefits were categorised as resource use conflict, environmental, governance, public safety, critical knowledge gaps and lack of access. An integrated threat and risk assessment approach found that the priority threats to community benefits were environmental threats (e.g., water pollution), critical knowledge gaps (e.g., inadequate social and economic information), governance (e.g., lack of compliance), resource-use conflict (e.g., anti-social behaviour), and lack of access (e.g., loss of fishing access). Threat and risk assessment is an evidence-based tool that is useful for marine planning because it provides a structured approach to incorporating multiple types of knowledge and enables limited resources to be targeted to the threats identified as being most important to address.

- Abstract
© 2019 Elsevier Ltd Regenerative agriculture, an alternative form of food and fiber production, concerns itself with enhancing and restoring resilient systems supported by functional ecosystem processes and healthy, organic soils capable of producing a full suite of ecosystem services, among them soil carbon sequestration and improved soil water retention. As such, climate change mitigation and adaptation are incidental to a larger enterprise that employs a systems approach to managing landscapes and communities. The transformative potential of regenerative agriculture has seen growing attention in the popular press, but few empirical studies have explored the processes by which farmers enter into, navigate, and, importantly, sustain the required paradigm shift in their approach to managing their properties, farm businesses, and personal lives. We draw on theories and insights associated with relational thinking to analyze the experiences of farmers in Australia who have undertaken and sustained transitions from conventional to regenerative agriculture. We present a conceptual framework of “zones of friction and traction” occurring in personal, practical, and political spheres of transformation that both challenge and facilitate the transition process. Our findings illustrate the ways in which deeply held values and emotions influence and interact with mental models, worldviews, and cultural norms as a result of regular monitoring; and how behavioral change is sustained through the establishment of self-amplifying positive feedbacks involving biophilic emotions, a sense of well-being, and an ever-expanding worldview. We conclude that transitioning to regenerative agriculture involves more than a suite of ‘climate-smart’ mitigation and adaptation practices supported by technical innovation, policy, education, and outreach. Rather, it involves subjective, nonmaterial factors associated with culture, values, ethics, identity, and emotion that operate at individual, hou

12. ‘Social license to operate’ in the Blue Economy

- Abstract
© 2019 The Authors The Blue Economy is an ocean based economic growth model gaining traction around the world. The way in which the Blue Economy is conceived and understood differs significantly across different sets of actors. A particular area of contestation exists around which ocean based industries or sectors can be considered to be ‘Blue’. This highlights the possibility of the Blue Economy becoming a forum through which the legitimacy of different private uses of ocean resources is contested and debated. The question of legitimacy of Blue Economy activities and sectors is explored through a critical engagement with the notion of a ‘social license to operate’ (SLO). Whilst SLO is normally considered in the context of individual businesses or developments, in this article we explore the applicability of SLO at a cross-sectoral scale. In doing so we examine how the concept of SLO may inform debates over appropriate private use of public ocean resources, and how this might influence the legitimacy of the broader concept of a Blue Economy. A case study involving a range of private sectors actors engaged in diverse ocean industries was conducted, drawing on interviews, a cross-sectoral survey and an interactive workshop with the ocean business community. The case study explores the role that SLO is currently playing in ocean industries. In particular we explore perceptions of who grants a SLO, what kind of concerns impact a SLO and how sectors work to obtain, or maintain, a SLO. By comparing the responses of individual sectors to these three critical questions, we identify that many of the SLO challenges currently being experienced by ocean industries relate to conflicting social and political values. This is creating a range of complex, sometimes irresolvable, SLO challenges for maritime industries, largely concentrated in sectors engaged in resource extraction, such as mining and oil and gas. In addition we find that attempts to address SLO challenges to date foc

- Abstract
© 2017 Human dimensions researchers and fisheries managers have long recognized the value of exploring the heterogeneity that exists amongst recreational fishers. Understanding the differences between fishers has the potential to assist managers in developing targeted communication strategies, direct resources to active management more efficiently and improve understanding of how fishers will respond to changes in regulations or new management interventions. Human dimensions research has traditionally explored fisher heterogeneity through research into the different reasons why people choose to fish, as well as attempts to categorize or segment fishers using variable based approaches. These studies have, to date, relied primarily on large scale, quantitative survey techniques with a particular focus on fisher avidity and commitment. They are therefore limited in their ability to explain how different fishing motivations might interact within an individual, why particular motivations are prioritized, and how this might influence fisher behavior and attitudes. This study trialed a mixed methods approach to understanding fisher heterogeneity based primarily on motivations using a case study in NSW, Australia. This trial involved utilizing a person-centered approach known as Latent Class Analysis (LCA), followed by qualitative, in depth focus group discussions. This revealed five distinct fisher classes; Social fishers, Trophy Fishers, Outdoor Enthusiasts, Generalists and Hunter-Gatherers, each with distinct and significantly different combinations of catch and non-catch-related motivations. The qualitative analysis sought to explore the intersection of motivations and attitudes towards management within and across the different fisher classes. The results highlighted the importance of more detailed examination of the intersection between motivations and attitudes in future LCA, with a particular focus on the potential influence of mastery (or challenge/experience) moti

- Abstract
© 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group. The ‘Blue Economy’ is an increasingly popular term in modern marine and ocean governance. The concept seeks to marry ocean-based development opportunities with environmental stewardship and protection. Yet different actors are co-opting this term in competing, and often conflicting ways. Four conceptual interpretations of the Blue Economy are identified, through examination of dominant discourses within international Blue Economy policy documents and key ‘grey’ literature. The way the Blue Economy is enacted is also examined, through an analysis of the Blue Economy ‘in practice’, and the actors involved. Finally, the scope of the Blue Economy is explored, with a particular focus on which particular marine industries are included or excluded from different conceptualizations. This analysis reveals areas of both consensus and conflict. Areas of consensus reflect the growing trend towards commodification and valuation of nature, the designation and delimitation of spatial boundaries in the oceans and increasing securitization of the world's oceans. Areas of conflict exist most notably around a divergence in opinions over the legitimacy of individual sectors as components of the ‘Blue Economy’, in particular, carbon-intensive industries like oil and gas, and the emerging industry of deep seabed mining.

- Abstract
© 2018 Indian Ocean Research Group. Maritime security is essential to supporting the Blue Economy. Many maritime security forums have been key supporters of the Blue Economy concept, particularly in the Indian Ocean region (IOR). This paper will explore the co-evolution and co-dependence of Blue Economy and maritime security agendas, with a particular focus on the IOR. It identifies two primary interactions between Blue Economy and maritime security interests. Firstly, maritime security is an enabler of the Blue Economy, for example, through safeguarding navigation routes, providing important oceanographic data to marine industries and protecting rights over valuable marine resources and activities within claimed zones of maritime jurisdiction. Secondly, an often overlooked role that maritime security plays in the Blue Economy is by being itself a source of economic development and growth. An expanded Blue Economy will create greater demand for maritime security capabilities, and this, in turn, will trigger increased investment and growth in these capabilities. The enhanced and increasingly diverse role that maritime security will continue to play in the Blue Economy can be seen across all sectors in the IOR.

Fisheries - Abstract
© 2016 Over recent decades it has become widely accepted that managing fisheries resources means managing human behaviour, and so understanding social and economic dynamics is just as important as understanding species biology and ecology. Until recently, fisheries managers and researchers have struggled to develop effective methods and data for social and economic analysis that can integrate with the predominantly biological approaches to fisheries management. The field is now growing fast, however, and globally, researchers are developing and testing new methods. This paper uses three divergent case studies to demonstrate the value of using qualitative social science approaches to complement more conventional quantitative methods to improve the knowledge base for fisheries management. In all three cases, qualitative interview and document review methods enabled broad surveying to explore the research questions in particular contexts and identified where quantitative tools could be most usefully applied. In the first case (the contribution of commercial fisheries to coastal communities in eastern Australia), a wellbeing analysis identified the social benefits from particular fisheries, which can be used to identify the social impacts of different fisheries management policies. In the second case (a gender analysis of fisheries of small islands in the Pacific), analysis outlined opportunities and constraints along fisheries supply chains, illuminated factors inhibiting community development and identified ecological factors that are typically overlooked in conventional fisheries management. In the third case (sea cucumber fisheries in Papua New Guinea), an interactive governance analysis assessed how well fisheries management tools fit the ecological, social and economic reality of the fishery and the trade in its products, including market influences and stakeholder values. The qualitative approach adopted in these three case studies adds a new dimension to understanding fisheries that is not possible with a focus solely on quantitative data. With the development of new policies on release programs (stock enhancement, restocking) and artificial reefs, and the momentum to use these interventions from recreational fishing groups, the qualitative approach will provide an important contribution to understanding their wider costs and benefits.

- Abstract
Marine protected areas (MPAs) are one approach, amongst many, for the protection of marine biodiversity. Although proven to be effective at protecting biodiversity and to be supported by local and wider communities, the implementation of some MPAs has been very contentious especially with fishing stakeholders. We researched the causes of these issues by examining the experience of implementation of the Batemans Marine Park in New South Wales, Australia. While MPA selection and management need to be based on rigorous science, a commensurate level of attention needs to be applied to understanding the social systems that also play a role in determining the protection measures and approaches. The most pressing issue that needs to be resolved early on in a planning process is the MPA's objectives, and whether these objectives are well understood and accepted by the local community. Building community support for MPAs also involves taking into account the different systems of knowledge and views of the natural world that exist within the community. Science alone is not sufficient to convince communities of the need for MPAs or their value in achieving conservation outcomes. Incorporating 'bottom-up' approaches into communication and engagement strategies will allow for a greater diversity of voices to be heard and acknowledged, protecting the planning processes against polarisation. Engaging local communities needs to go beyond large-scale consultation processes to include more rigorous, integrated social, economic and ecological assessment exercises, involving a collaborative participatory approach. Context is important and planning processes need to recognise the individual and unique needs of each affected community. Rigid ideas around the best means of achieving biodiversity protection combined with 'a one size fits all' approach to planning and community engagement are likely to exacerbate conflict and division and stimulate opposition.

- Abstract
© 2016 Resource conflict is a common feature of coastal management. This conflict is often managed by using spatial planning tools to segregate uses, with access decisions made through a comparison of the economic costs and benefits of the competing sectors. These comparisons rarely include an in-depth analysis of the extent or nature of the conflict. One commonly experienced form of resource conflict in coastal communities involves professional fishing, recreational fishing and broader coastal tourism. In New South Wales, Australia the professional fishing industry is often seen as being in conflict with recreational fishing and tourism, and there are frequent calls to close areas to professional fishing, arguing that this will provide improved economic benefits to local communities. This research examined the relationships between the three sectors using economic valuations, qualitative interviews and a large-scale representative questionnaire of the general public. The results revealed highly interconnected and mutually supportive relationships, with professional fishing providing a range of services that benefit both tourism and recreational fishing. These results suggest that spatial management exercises that seek to segregate or remove one sector from an area, may be counterproductive to the interests of all these groups. Relying on economic valuations of each sector as if they stand alone is insufficient to adequately understand their roles in local communities. Resource allocation decisions should be based on evaluations that consider the interconnections between sectors, and consider whether negotiated sharing of resources may provide greater community benefits than excluding certain groups of users.

- Abstract
© 2017 John Wiley & Sons Ltd The principles of Ecologically Sustainable Development and Ecosystem Based Fisheries Management require that fisheries be managed for social as well as environmental and economic objectives. Comprehensive assessments of the success of fisheries in achieving all three objectives are, however, rare. There are three main barriers to achieving integrated assessments of fisheries. Firstly, disciplinary divides can be considered “too hard” to bridge with inherent conflicts between the predominately empirical and deductive traditions of economics and biophysical sciences and the inductive and interpretative approach of much of the social sciences. Secondly, understanding of the social pillar of sustainability is less well developed. And finally, in-depth analysis of the social aspects of sustainability often involves qualitative analysis and there are practical difficulties in integrating this with largely quantitative economic and ecological assessments. This article explores the social well-being approach as a framework for an integrated evaluation of the social and economic benefits that communities in New South Wales, Australia, receive from professional fish harvesting. Using a review of existing literature and qualitative interviews with more than 160 people associated with the fishing industry the project was able to identify seven key domains of community well-being to which the industry contributes. Identification of these domains provided a framework through which industry contributions could be further explored, through quantitative surveys and economic analysis. This framework enabled successful integration of social and economic, and both qualitative and quantitative information in a manner that enabled a comprehensive assessment of the value of the fishery.

- Abstract
The amount of carbon present in Earth’s mantle affects the dynamics of melting, volcanic eruption style and the evolution of Earth’s atmosphere via planetary outgassing. Mantle carbon concentrations are difficult to quantify because most magmas are strongly degassed upon eruption. Here we report undegassed carbon concentrations from a new set of olivine-hosted melt inclusions from the Mid-Atlantic Ridge. We use the correlations of CO2 with trace elements to define an average carbon abundance for the upper mantle. Our results indicate that the upper mantle carbon content is highly heterogeneous, varying by almost two orders of magnitude globally, with the potential to produce large geographic variations in melt fraction below the volatile-free solidus. Such heterogeneity will manifest as variations in the depths at which melt becomes interconnected and detectable, the CO2 fluxes at mid-ocean ridges, the depth of the lithosphere-asthenosphere boundary, and mantle conductivity.

Objectives: To assess the relation between cigarette smoking during pregnancy and neonatal respiratory distress syndrome (RDS) in very preterm birth, and to analyse the differential effect of antenatal steroids on RDS among smokers and non-smokers. Design: A population based cohort study (the French Epipage study). Setting: Regionally defined births in France. Methods: A total of 858 very preterm liveborn singletons (27–32 completed weeks of gestation) of the French Epipage study were included in this analysis. The odds ratio for RDS in relation to smoking in pregnancy was estimated using a logistic regression to control for gestational age. The odds ratio for RDS in relation to antenatal steroids was estimated taking into account an interaction between antenatal steroids and cigarette smoking, using multiple logistic regression to control for gestational age, birthweight ratio, main causes of preterm birth, mode of delivery, and sex. Results: The odds ratio for RDS in relation to smoking in pregnancy adjusted for gestational age (aOR) was 0.59 (95% confidence interval (CI) 0.44 to 0.79). The aOR for RDS in relation to antenatal steroids was 0.31 (95% CI 0.19 to 0.49) in babies born to non-smokers and 0.63 (95% CI 0.38 to 1.05) in those born to smokers; the difference was significant (p = 0.04). Conclusions: Cigarette smoking during pregnancy is associated with a decrease in the risk of RDS in very preterm babies. Although antenatal steroids reduce the risk of RDS in babies born to both smokers and non-smokers, the reduction is smaller in those born to smokers.

Marine Biology & Hydrobiology - Abstract
Marine protected areas (MPAs), are being vigorously pursued globally but meeting significant resistance at a local level. Despite this, there is limited research into the factors that drive this resistance. The Port Stephens-Great Lakes Marine Park (PSGLMP) and Batemans Marine Park (BMP), both situated in New South Wales (NSW) Australia, were established in December 2005 and April 2006 respectively. Both generated significant controversy and hostility, particularly from the recreational fishing sector. The controversy surrounding the declaration of these and other NSW marine parks continues and has been the subject of intense political interest and government enquiry. Semi-structured interviews were conducted with recreational, professional and indigenous fishers. They explored the social impacts of the declaration of PSGLMP and BMP and their link to marine park opposition. Opponents felt the marine parks had resulted in a variety of negative impacts ranging from a loss of enjoyment and convenience through to more serious impacts on wellbeing, livelihood and culture. Examination of the reasons why interview subjects participated in fishing provided further insight into their perception of the marine park and the impacts resulting from the declaration. Opposition to MPAs, however, cannot be explained by impact alone. All the marine park opponents interviewed represented themselves as 'knowledge holders' about their local marine area. This knowledge - predominately 'fish' knowledge - appears to have conflicted with a policy position which places biodiversity conservation as the primary objective of MPAs. This has led to a perception that the practical knowledge of users was not valued in the planning of each marine park. Incorporation of the goals and objectives of local communities into the development of MPA proposals may provide communities with a greater sense of ownership. Considering motivation to fish may allow for the development of more holistic management responses to mitigate and compensate users for social impacts that may arise from any necessary trade-offs between these often competing objectives. © 2013 John Wiley & Sons, Ltd.

- Abstract
© 2014 Elsevier Ltd. Improving the social acceptability or 'social licence' of Marine Protected Areas (MPAs) is a key challenge facing countries all around the world. As the world moves slowly towards the establishment of a global network of MPAs, it is increasingly apparent that a greater understanding of social responses to MPAs is required, given they are often met with resistance from local communities. A series of in-depth, semi structured interviews were conducted across coastal users in New South Wales, Australia, including surfers, recreational fishers, professional fishers, spearfishers, walkers, divers, snorkellers, kayakers and other community members. The research identified the values, images and principles at work amongst coastal users to determine the dominant 'cultural models' within the community and how these models influenced attitudes towards MPAs. This research indicates that traditional consultation models may not be sufficient to address the full spectrum of community needs, and in fact suggests the need to re-conceive the make -up of 'the community' itself. In the context of MPA planning 'the community' is not an amalgamation of a range of homogenous stakeholder groups but instead a diverse and complex mix of identities and value systems which are not confined to particular interest groups. Incorporating consideration of the diverse range of values, images and principles found within and across stakeholder groups will require new and innovative approaches to participation and management.

- Abstract
Has the hype associated with the «revolutionary» potential of the World Wide Web and digital media for environmental activism been muted by the past two decades of lived experience? What are the empirical realities of the prevailing media landscape? Using a range of related disciplinary perspectives, the contributors to this book analyze and explain the complicated relationship between environmental conflict and the media. They shine light on why media are central to historical and contemporary conceptions of power and politics in the context of local, national and global issues and outline the emerging mixture of innovation and reliance on established strategies in environmental campaigns. With cases drawn from different sections of the globe Australia, the United Kingdom, the United States, Europe, Latin America, China, Japan, the Pacific Islands, Africa the book demonstrates how conflicts emanate from and flow across multiple sites, regions and media platforms and examines the role of the media in helping to structure collective discussion, debate and decision-making.

The diffusivities of volatile elements in silicate melts significantly impact petrological processes [e.g. 1, 2]. Although many studies of volatile diffusion in silicic melts have been undertaken, there have been few studies in basaltic melts [e.g. 3], and most of these have concentrated on the diffusion of only one or two elements in each experiment.

- Abstract
Mass media is a key tool by which environmental interventions, such as Marine Protected Areas (MPAs) are communicated to the public. The way in which local news outlets present and explain MPAs to local communities is likely to be influential in determining how they respond to the proposal. In particular the tendency of news media to focus on areas of conflict and dispute ensures ideology and politics play a central role in reporting of MPA proposals, often simplifying debate into an 'us versus them' or 'fishers versus conservationists' ideological conflict. This can lead to the outright rejection of an MPA or undermine acceptance of the park within local communities. The media coverage of two marine parks in NSW, Australia was compared to determine the way in which news presented the parks to each community and how this may have influenced public acceptance of the parks. In particular the study examined the role ideology and politics played in the news coverage of each park by investigating the way in which the news was framed and the positions of key media spokespeople. Media coverage of the Batemans Marine Park appears to have been highly politicised and heavily influenced by the strong convictions of a small handful of prominent spokespeople. By way of contrast media coverage of the Port Stephens Great Lakes Marine Park was more nuanced and drew from a wide range of sources. This research provides insight into how areas of conflict could be reframed as opportunities that enhance MPA planning exercises and highlights how ideology can help shape community sentiment. Acknowledging the role of ideology in contested areas such as these allows for the development of strategies that can accommodate as well as moderate its influence. These strategies may include the incorporation of 'bottom up' approaches into MPA planning, the promotion and support of a range of voices within the community, and seeking out and building upon common ground and shared values. © 2013 Elsev

- Abstract
Has the hype associated with the «revolutionary» potential of the World Wide Web and digital media for environmental activism been muted by the past two decades of lived experience? What are the empirical realities of the prevailing media landscape? Using a range of related disciplinary perspectives, the contributors to this book analyze and explain the complicated relationship between environmental conflict and the media. They shine light on why media are central to historical and contemporary conceptions of power and politics in the context of local, national and global issues and outline the emerging mixture of innovation and reliance on established strategies in environmental campaigns. With cases drawn from different sections of the globe Australia, the United Kingdom, the United States, Europe, Latin America, China, Japan, the Pacific Islands, Africa the book demonstrates how conflicts emanate from and flow across multiple sites, regions and media platforms and examines the role of the media in helping to structure collective discussion, debate and decision-making.

- Abstract
Addressing social and economic considerations is crucial to the success of Marine Protected Area (MPA) planning and management. Ineffective social assessment can alienate local communities and undermine the success of existing and future MPAs. It is rare to critique the success of methods used currently to incorporate social and economic considerations into MPA planning. Three Australian MPA planning processes covering three states and incorporating federal and state jurisdictions are reviewed in order to determine how potential social impacts were assessed and considered. These case studies indicate that Social Impact Assessment (SIA) is under-developed in Australian MPA planning. Assessments rely heavily on public participation and economic modelling as surrogates for dedicated SIA and are followed commonly by attitudinal surveys to gauge public opinion on the MPA after its establishment. The emergence of issues around public perception of the value of MPAs indicates the failure of some of these proposals to adequately consider social factors in planning and management. This perception may have potential implications for the long term success of individual MPAs. It may also compromise Australia's ability to meet international commitments for MPA targets to gazette at least 10% of all its marine habitats as MPAs. Indeed, this is demonstrated in two of the three case studies where social and economic arguments against MPAs have been used to delay or block the future expansion of the MPA network. © 2011 Elsevier Ltd.

In addition to the abundant andesite and dacite lavas of the Mt. Shasta stratocone, primitive mafic lavas have erupted during the Quaternary from the Mt. Shasta region. Two types of basic lavas are the focus of this study: nearly anhydrous high-aluminium olivine tholeiites, produced by decompression melting, and basaltic andesites, produced by melting of a metasomatized mantle source (i.e. modified by various amounts of H2O-rich components). Here we provide further insight into the origin and the coexistence of these two types of magma based on a detailed study of the dissolved volatile contents in melt inclusions trapped in magnesium-rich olivine crystals from both tholeiites and basaltic andesites. The melt inclusions fall on the primitive extension of their respective host lava compositions: (1) the tholeiite melt inclusions are nearly anhydrous melts with low and clustered volatiles compositions; (2) the basaltic andesite melt inclusions are ‘wet’ melts with higher and more variable volatile contents (up to 2·6 wt% H2O, 820 ppm CO2, 1270 ppm Cl, 1220 ppm F and 6280 ppm S) than those of the tholeiite melt inclusions. The basaltic andesite melt inclusions are enriched in fluid-mobile elements and in incompatible trace elements: they display a stronger signature of slab-derived components than their host lavas. The selective enrichment of the basaltic andesite melt inclusions in fluid-mobile elements such as K, F, Cl, Ba and B as well as their contrasting δ11B (from −10·2 ± 1·3‰ to −3·2 ± 0·9‰ for the melt inclusions from sample 95-15 and from −4·9 ± 1·1‰ to +4·4 ± 1·1‰ for the melt inclusions from samples 85-1a and 85-47) show the imprints of two distinct slab-derived components C1 and C2. Using trace element ratios, we modelled the compositions of these two H2O-rich components (C1 with Cl/F of 1·1 is rich in both in high field strength elements and incompatible trace elements, whereas C2 with Cl/F of 4·0 is poorer in trace elements) and show that they represent mixing between sediment melts and dehydration fluids from the altered oceanic crust.

- Abstract
Production calculations for a tidal power station. With advance knowledge of tidal level variations it is possible to calculate accurately the power output to be expected from a tidal power station in a given site. M. Gibrat has worked out a complete theory defining optimum operating conditions during emptying or filling of the basin, with the power units working either as pumps or turbines. The purpose of the first investigations for the Rance tidal power station was to obtain maximum power output. The new submerged type units proposed for the Rance work with good efficiency for both directions of flow, and make it possible to choose daily the operating conditions best adapted to power needs. The tidal power station will be operated in “variable cycles” : taking into account the time of the tide an attempt can be made to concentrate power production in the working hours («heures pleines») or peak-time hours («heures de pointe»), or to distribute it so as to use as little coal as possible in thermal power stations., La connaissance à l'avance des variations de niveau de la marée, permet de calculer avec précision les performances énergétiques à attendre d'une usine marémotrice projetée dans un site donné. M. Gibrat a établi la théorie complète définissant le fonctionnement optimal lors d'un vidage ou d'un remplissage du bassin, les groupes fonctionnant soit en turbine, soit en pompe. Les premières études, dans le cadre de l'usine de la Rance, eurent pour objectif la recherche du maximum d'énergie. Les nouveaux groupes immergés projetés sur la Rance, qui fonctionnent avec de bons rendements dans les deux sens d'écoulement, permettent de choisir une exploitation chaque jour adaptée au mieux des besoins de la consommation. L'usine marémotrice sera exploitée à «cycles variables» : en tenant compte de l'horaire de la marée, on pourra chercher à concentrer la production sur les heures pleines ou les heures de pointe, ou à la répartir de manière à économiser au maximum le charbon consommé par les centrales thermiques., Voyer M., Penel M.

- Abstract
The Blue Economy is a catch all term that is used to describe a wide variety of development approaches and priorities in the ocean and coastal areas. A number of distinct, and sometimes conflicting discourses have emerged in relation to the Blue Economy, which are distinguished by the degree to which they prioritize different development objectives. This paper explores the range of Blue Economy interpretations, governance strategies and implementation approaches that exist across Commonwealth countries. Key Blue Economy policy statements and governance instruments are analysed in order to ascertain the way the Blue Economy is being institutionalized at a national level, with reference to the Sustainable Development Goals and the Commonwealth Blue Charter. High-level Blue Economy objectives appear to prioritize economic and environmental objectives, with limited engagement with equity objectives including food security and gender equality. Blue Economy objectives are primarily being institutionalized through a diverse array of strategies, plans and policies with limited information on mechanisms for implementation. Finally, there are signs that the Blue Economy may be facilitating a greater degree of integration across sectoral management, with the emergence of range of boundary-crossing arrangements in a number of the countries examined. This article is part of the theme issue 'Nurturing resilient marine ecosystems'.

40. The carbon content of Earth and its core.

- Abstract
Earth's core is likely the largest reservoir of carbon (C) in the planet, but its C abundance has been poorly constrained because measurements of carbon's preference for core versus mantle materials at the pressures and temperatures of core formation are lacking. Using metal-silicate partitioning experiments in a laser-heated diamond anvil cell, we show that carbon becomes significantly less siderophile as pressures and temperatures increase to those expected in a deep magma ocean during formation of Earth's core. Based on a multistage model of core formation, the core likely contains a maximum of 0.09(4) to 0.20(10) wt% C, making carbon a negligible contributor to the core's composition and density. However, this accounts for ∼80 to 90% of Earth's overall carbon inventory, which totals 370(150) to 740(370) ppm. The bulk Earth's carbon/sulfur ratio is best explained by the delivery of most of Earth's volatiles from carbonaceous chondrite-like precursors., Competing Interests: The authors declare no competing interest.

41. Heterogeneity in mantle carbon content from CO 2 -undersaturated basalts.

- Abstract
The amount of carbon present in Earth's mantle affects the dynamics of melting, volcanic eruption style and the evolution of Earth's atmosphere via planetary outgassing. Mantle carbon concentrations are difficult to quantify because most magmas are strongly degassed upon eruption. Here we report undegassed carbon concentrations from a new set of olivine-hosted melt inclusions from the Mid-Atlantic Ridge. We use the correlations of CO
2 with trace elements to define an average carbon abundance for the upper mantle. Our results indicate that the upper mantle carbon content is highly heterogeneous, varying by almost two orders of magnitude globally, with the potential to produce large geographic variations in melt fraction below the volatile-free solidus. Such heterogeneity will manifest as variations in the depths at which melt becomes interconnected and detectable, the CO2 fluxes at mid-ocean ridges, the depth of the lithosphere-asthenosphere boundary, and mantle conductivity.- Published

- Abstract
As gut immaturity precludes full enteral feeding, very low birth weight (VLBW) preterm infants receive parenteral nutrition (PN) during the first few weeks of life. Weaning VLBW infants off PN, however, is a top priority since PN is associated with a high risk of complications. The decision making is purely empirical, as there is currently no suitable index of gastrointestinal (GI) maturity. Plasma citrulline concentration is considered an index of GI function in conditions such as short-bowel syndrome and coeliac disease in adults. To identify the factors determining urinary citrulline excretion, and determine whether urinary citrulline excretion could be used as a non-invasive index of GI tolerance to enteral feeding, nutritional intake and urinary citrulline were monitored bi-weekly in forty-seven preterm infants < 1500 g (interquartiles 880-1320 g), during their stay in the Neonatology unit. Median urinary citrulline was 24·7 μmol/mmol creatinine (14·5-38·6 μmol/mmol creatinine). No relationship was observed with the percentage of energy tolerated enterally. In multivariate regression analysis, weak correlations were found with post-conceptional age (P = 0·001), parenteral amino acid supply (P = 0·001) and the daily volume of enteral mixture administered (P = 0·043). A significant correlation was found with urinary nitrite+nitrate excretion (r 0·47; P < 0·001). We conclude that in preterm infants: (1) one of the major determinants of urinary citrulline may be the biosynthesis of citrulline from arginine by NO-synthase; (2) urinary citrulline cannot be used to predict GI tolerance. This is consistent with the observations that, in neonatal gut, citrulline is converted to arginine in situ rather than exported towards the kidneys as observed in adults.

- Abstract
Background: Fecal calprotectin has been proposed as a non-invasive marker of intestinal inflammation in inflammatory bowel disease in adults and children. Fecal calprotectin levels have been reported to be much higher in both healthy full-term and preterm infants than in children and adults., Objective: To determine the time course of fecal calprotectin (f-calprotectin) excretion in preterm infants from birth until hospital discharge and to identify factors influencing f-calprotectin levels in the first weeks of life, including bacterial establishment in the gut., Methodology: F-calprotectin was determined using an ELISA assay in 147 samples obtained prospectively from 47 preterm infants (gestational age, and birth-weight interquartiles 27-29 weeks, and 880-1320 g, respectively) at birth, and at 2-week intervals until hospital discharge., Principal Findings: Although median f-calprotectin excretion was 138 microg/g, a wide range of inter- and intra-individual variation in f-calprotectin values (from day 3 to day 78) was observed (86% and 67%, respectively). In multivariate regression analysis, f-calprotectin correlated negatively with ante and per natal antibiotic treatment (p = 0.001), and correlated positively with the volume of enteral feeding (mL/kg/d) (p = 0.009), the need to interrupt enteral feeding (p = 0.001), and prominent gastrointestinal colonization by Clostridium sp (p = 0.019) and Staphylococcus sp (p = 0.047)., Conclusion: During the first weeks of life, the high f-calprotectin values observed in preterm infants could be linked to the gut bacterial establishment.

- Abstract
Background: Although recent reports suggest that supplementation with probiotics may enhance intestinal function in premature infants, the mechanisms are unclear, and questions remain regarding the safety and efficacy of probiotics in extremely low-birth-weight infants., Objective: The objective was to evaluate the efficacy of probiotics on the digestive tolerance to enteral feeding in preterm infants born with a very low or extremely low birth weight., Design: In a bicentric, double-blind, randomized controlled clinical trial that was stratified for center and birth weight, 45 infants received enteral probiotics (Bifidobacterium longum BB536 and Lactobacillus rhamnosus GG; BB536-LGG) and 49 received placebo. The primary endpoint was the percentage of infants receiving >50% of their nutritional needs via enteral feeding on the 14th day of life. A triangular test was used to perform sequential analysis., Results: The trial was discontinued after the fourth sequential analysis concluded a lack of effect. The primary endpoint was not significantly different between the probiotic (57.8%) and placebo (57.1%) groups (P = 0.95). However, in infants who weighed >1000 g, probiotic supplementation was associated with a shortening in the time to reach full enteral feeding (P = 0.04). Other than colonization by the probiotic strains, no alteration in the composition of intestinal microbiota or changes in the fecal excretion of calprotectin was observed. No colonization by probiotic strains was detected in infants who weighed < or =1000 g, presumably because of more frequent suspensions of enteral feeding, more courses of antibiotic treatment, or both., Conclusions: Supplementation with BB536-LGG may not improve the gastrointestinal tolerance to enteral feeding in very-low-birth-weight infants but may improve gastrointestinal tolerance in infants weighing >1000 g. This trial was registered at clinicaltrials.gov as NCT 00290576.

- Abstract
It was hypothesised that diaphragm injury activates a time-based programme of gene expression in muscle repair. Gene expression of different substances, such as proteases (calpain 94 (p94)), transcription factors (myogenin and cFos), growth factors (both basic fibroblast growth factor (bFGF) and insulin-like growth factor (IGF)-II), and structural proteins (myosin heavy chain (MHC) and titin), was quantified by RT-PCR in rat diaphragms exposed to caffeine-induced injury. Injured and noninjured (control) rat hemidiaphragms were excised at different time points (1-240 h). In injured hemidiaphragms, in comparison with control muscles, p94 expression levels peaked at 1 h post-injury (PI), cFos mRNA levels began to rise, after an initial dip, and peaked at 96 h PI, while myogenin mRNA levels started to increase as early as 12 h PI, IGF-II mRNA levels initially decreased until 48 h PI and increased thereafter, peaking at 72 h PI, bFGF mRNA levels rose to a maximum at 96 h PI, and MHC and titin mRNA levels were significantly elevated at 72 h PI. Caffeine-induced diaphragm injury is followed by a time-based expression programme of different genes tailored to meet muscle repair needs.

- Abstract
Two patients with trisomy 11p15 and features of Beckwith-Wiedemann syndrome are reported. The first is a female infant with gigantism, macroglossia, abdominal hypotonia with umbilical hernia, moderate mental retardation, malformative uropathy, and atrial septal defect. Trisomy 11p15 was due to de novo duplication. The second patient was a stillborn (32-33 weeks pregnancy) with an abnormal tongue, posterior diaphragmatic eventration, inner organ congestion mainly of the adrenals. Trisomy 11p15 was due to a t(4;11)(q33;p14)pat. The association of trisomy 11p15 and Beckwith-Wiedemann syndrome is discussed with regard to cytogenetic data and the gene content of 11p, notably the genes coding for insulin and predisposition to Wilms tumour.
