    Carbon Property Rights in Soil

    Full text link
    The commodification of soil to permit carbon sequestration and hence trading in the resultant carbon rights is examined as an emerging facet of climate change management. As the developed world moves towards carbon offsets and decarbonisation, the Australian continent provides a capacity to be a land based repository of carbon in either select species of vegetation grown specifically for this purpose, or where soil is conserved to sequestrate carbon. A presumption exists that carbon is sequestrated differentially in various soil landscapes, which typically comprise a mixture of different soil types. Diffuse boundaries between soil landscapes and significant differences assigned to same soil landscapes, albeit in different areas, significantly impacts sequestration of carbon

    Background and methods: We conducted an all-Ireland population-based prospective epidemiological survey of motor neurone disease (MND) using the Northern Ireland and Republic of Ireland MND registers to examine the incidence and prevalence of the disease over the period 2004–2005.Results and conclusions: Incidence of MND was 1.9 per 100 000 person-years and rates were comparable in both the north and south of Ireland. Prevalence of MND was 5.0 per 100 000 population. When compared with previous published surveys of MND performed in the Republic of Ireland over the last 10 years, rates of disease have remained relatively constant. When standardized to the 1990 US population, the incidence of MND in Ireland was found to be consistent with other European prospective surveys of MND

    Dune formation on the present Mars

    We apply a model for sand dunes to calculate formation of dunes on Mars under the present Martian atmospheric conditions. We find that different dune shapes as those imaged by Mars Global Surveyor could have been formed by the action of sand-moving winds occuring on today's Mars. Our calculations show, however, that Martian dunes could be only formed due to the higher efficiency of Martian winds in carrying grains into saltation. The model equations are solved to study saltation transport under different atmospheric conditions valid for Mars. We obtain an estimate for the wind speed and migration velocity of barchan dunes at different places on Mars. From comparison with the shape of bimodal sand dunes, we find an estimate for the timescale of the changes in Martian wind regimes.Comment: 16 pages, 12 figure

    An evaluation framework to determine the impact of the Lyme Bay Fisheries and Conservation Reserve and the activities of the Lyme Bay Consultative Committee on ecosystem services and human wellbeing.

    This research evaluates the social and economic impact of the management measures that form the Lyme Bay Reserve and the partnership activities of the Lyme Bay Consultative Committee (LBCC) on Lyme Bay resource users. For the purpose of this evaluation it is the combination of the 2008 Statutory Instrument (SI) closure and the more recently designated Site of Community Interest (SCI) that form the boundary of the Lyme Bay Fisheries and Conservation Reserve, termed as the Lyme Bay Reserve. Data is analysed between 2005 and 2015. The results show that the habitats and species of Lyme Bay interact to support the delivery of several ecosystem processes (e.g. primary and secondary production, formation of species habitat) and the realisation of ecosystem services (e.g. fish for food). Overall it is clear that the closure of the area to mobile fishing gear has benefitted static gear fishermen by separating spatial conflict between gear types. The closure has enabled reef habitats to recover which in turn has supported increased catches of some reef associated species e.g. scallops. Further management and support measures agreed through the LBCC have clearly been successful in improving the well-being for those fishermen directly involved in the project. This research represents collaboration between Plymouth University, Exeter University, The Blue Marine Foundation and CEFAS. Input into the evaluation was provided by the Devon and Severn Inshore Fisheries and Conservation Authority (IFCA), the Southern IFCA, local fishermen and fishery representatives

    ‘Deliberate Preparation’ as an evidence-based focus for primary physical education

    Get PDF
    There is substantial scientific research suggesting the physical and psychological health benefits of a physically active lifestyle. Consequently, governments worldwide prioritize policies, finances, and resources in healthcare, education, and sports sectors to increase mass participation in physical activity. However, practices in physical activity promotion are often not underpinned by evidence-based standardization that is requisite in other domains of epidemiology. The aim of this article is to examine critically the available scientific research on promoting life-long physical activity participation and to propose an evidence-based model for implementation in school physical education. Reasons are discussed as to why programs that integrate physical, psychological, and behavioral skills have been long acknowledged in physical education and physical activity domains but remain lacking in empirical validation. Finally, future directions are suggested that are required to examine the application of this approach to practice in primary-level physical education

    Interlayer Registry Determines the Sliding Potential of Layered Metal Dichalcogenides: The case of 2H-MoS2

    Full text link
    We provide a simple and intuitive explanation for the interlayer sliding energy landscape of metal dichalcogenides. Based on the recently introduced registry index (RI) concept, we define a purely geometrical parameter which quantifies the degree of interlayer commensurability in the layered phase of molybdenum disulphide (2HMoS2). A direct relation between the sliding energy landscape and the corresponding interlayer registry surface of 2H-MoS2 is discovered thus marking the registry index as a computationally efficient means for studying the tribology of complex nanoscale material interfaces in the wearless friction regime.Comment: 13 pages, 7 figure

    Death ideation in cancer patients: contributing factors

    Get PDF
    Advances in cancer research and therapy have improved prognosis and the quality of life of many patients. However, previous epidemiological studies in oncologic patients have shown an increased risk of suicide. Suicidal thoughts, relatively well known in those terminally ill, may be just as important for cancer patients who are survivors or are living with the disease. Nonetheless, there is a relative paucity of data about suicidality in this setting. The authors conducted a prospective observational study to identify death thoughts and to explore the factors associated with suicidal ideation in cancer patients. A sample of 130 patients referred for psychiatric consultation was obtained following informed consent and authorization from the local ethics committee. A semistructured interview assessed sociodemographic data, psychosocial support, and information regarding the cancer process and its treatment. Psychometric instruments were used to evaluate psychopathology, namely the Hospital Anxiety and Depression Scale, the Beck Hopelessness Scale, and the Beck Scale for Suicide Ideation. Psychiatric diagnoses were obtained through the application of the Mini International Neuropsychiatric Interview. Death ideation was identified in 34.6% of patients, yet only 10% had active suicidal thoughts. Risk of suicide was associated with female gender, a psychiatric diagnosis (major depressive disorder, panic disorder, or dysthymia), difficult interpersonal relationships, associated pain, high hopelessness, and depressive and anxiety symptoms. Although suicidal thoughts are frequent in cancer patients at different stages of disease, most are transitory. Risk factors for suicidal ideation have been identified, such as depression, hopelessness, uncontrolled pain, and difficult interpersonal relationships. Further assessment is necessary to identify those at higher risk of attempting suicide, and underlying psychiatric disorders should be vigorously treated

    Castro\u27s Shifters: Locating Variation in Political Discourse

    Get PDF
    In his trademark speeches, Fidel Castro casts himself in a variety of roles: supreme leader, member of government, revolutionary, worker, member of the Cuban populace, and the embodiment of the Cuban nation. Transcripts of Castro’s major speeches provide a rich data set that spans five decades (1959-present). Initial readings reveal his prominent use of the first person plural nosotros , which suggests an intriguing discourse of inclusiveness for this long-time authoritarian leader. In this poster, we identify Castro’s variable discursive referents for nosotros verbs in relation to era and topic of speech (i.e., history of the revolution, national goals and progress, or trouble talk). Variable rule analysis shows that in Castro’s earlier speeches, use of the royal we variant is favored: Llamábamos al Partido por la noche, y le preguntábamos si había llovido o no ( We called the Party the other night, and we asked if it had rained or not ). In contrast, the use of what we term the collective we is favored most heavily in speeches after the fall of the Soviet Union: No estamos produciendo para los burgueses, estamos produciendo para el pueblo ( We’re not producing for the bourgeoisie, we’re producing for the people ). The variation we encounter reflects Castro’s positioning of self relative to the people he is addressing. Castro, as leader of the perpetual revolutionary state, ostensibly erases the possibility of a public sphere existing apart from the government by constructing what the public thinks/expresses/wants as what the government [naturally] does. This is as we might expect in a Marxist dictatorship of the proletariat. Castro, however, achieves this conflation of public sphere and public authority in two ways in his speeches: first, he relocates public authority outside of the immediate social context, so that the role played by the Cuban public and the revolutionary government is one and the same when viewed in opposition to Yankee imperialism or memories of the Batista regime, for example. Second, by including himself in nosotros talk about workers and revolutionaries while standing over and addressing the Cuban public, Castro projects himself into the crowd. The effect of such talk is to offer an answer to the question, Who mediates between the private sphere and the government in a socialist society where each one is identified with the other? Castro proposes himself as the answer; he, not any autonomous, Habermasian sphere of rational debate, mediates between people’s private lives and the actions of state authority. Thus, what we term a personal public sphere provides a context for understanding the pattern of variation we observe in Castro’s speeches
