Is randomized branch sampling suitable to assess wood volume of temperate broadleaved old-growth forests?
Old-growth forests are characterized by the presence of large and very large trees. The estimation of their wood volume and biomass is essential in order to monitor the ecological processes in these stands and
their contribution to carbon cycle. However, conventional wood volume estimation techniques based on mensuration of stem diameter at breast height and tree height is most often unfeasible for large and very large trees in old-growth forests because volume models or tables are usually elaborated from trees of smaller size grown up in regularly managed forest stands. Random Branch Sampling (RBS) is often proposed as a possible estimation alternative under such conditions. Starting from the ground level
some of the parts of the main trunk and of the branches are sampled and measured to estimate the overall wood volume (or other biophysical variables). The application of RBS in old-growth forests, where tree
cutting is usually forbidden or very difficult, requires that the crown of the tree can physically be reached to measure the sampled parts. We argue that under such conditions it is usually preferable to fully measure all the components of the tree crown because RBS estimates are not precise if based on only one sampling path and that, on the other hand, measuring the main trunk and all the branches by tree-climbing consumes the same time as replicating several RBS paths on the same tree. To demonstrate our
hypothesis we selected 16 large beech trees located in the old-growth forest of Mount Cimini in Central Italy. Using a modern tree-climbing approach the main trunk and all the branches were measured and recorded in the field. The database was used to simulate RBS paths. Real values from volume census were
contrasted with estimates based on RBS. On the whole, RBS estimates based on one single path prove to be highly imprecise. Even for trees characterized by a rather regular form, at least three RBS paths should be repeated on the same tree to maintain the relative standard error under or near 15%. This paper introduces the problem and describes the experimental test. The results are discussed under the perspective of standardized application of the proposed methodology.L'articolo è disponibile sul sito dell'editore www.journals.elsevier.co
Management of eyelid trauma
The management of eyelid trauma presents some frustrating challenges to the general ophthalmologist. Because each case is unique, adaptation of general principles is essential for optimal ophthalmic treatment. This review includes the essentials of approaches to the evaluation and treatment of eyelid margin and canalicular lacerations. Specific attention is directed towards avoidance of complications.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71612/1/j.1442-9071.1991.tb00686.x.pd
A flawed construct? Understanding and unpicking the concept of resilience in the context of economic hardship
Increasingly, the construct of resilience has been used by social scientists and (social) policy makers in relation to individual resilience to economic hardship. There are a number of issues within the literature on the subject that are unresolved including: whether it is an attribute or a process; the extent to which resilience is a positive phenomenon; the extent to which individuals living in economic hardship have agency; and, whether it is finite. The article unpacks these issues, drawing on qualitative data from a longitudinal study in Northern Ireland. It found resilience to be a negative experience for study participants, although they did exhibit a number of attributes that may be described as being positive. They were often unable to exercise 'positive', transformative agency, because the choices available were limited and pernicious in nature. The paper concludes that as an analytical tool for exploring the experiences of people living in economic hardship the construct of resilience is not helpful
Making the great transformation, November 13, 14, and 15, 2003
This repository item contains a single issue of the Pardee Conference Series, a publication series that began publishing in 2006 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future. This Conference took place during November 13, 14, and 15, 2003. Co-organized by Cutler Cleveland and Adil Najam.The conference discussants and participants analyze why transitions happen, and why they matter. Transitions are those wide-ranging changes in human organization and well being that can be convincingly attributed to a concerted set of choices that make the world that was significantly and recognizably different from the world that becomes.
Transition scholars argue that that history does not just stumble along a pre-determined path, but that human ingenuity and entrepreneurship have the ability to fundamentally alter its direction. However, our ability to ‘will’ such transitions remains in doubt. These doubts cannot be removed until we have a better understanding of how transitions work
Leprosy patients profile registered in the university clinical center in Patos de Minas
Leprosy is an infectious disease caused by mycobacterium leprae and manifests mainly through dermatoneurological signs and symptoms. The objective of this study was to describe the clinical and epidemiological profile of leprosy patients enrolled at the university clinical center. An interview script was prepared for 33 patients regarding socioeconomic, demographic, environmental and clinical conditions. The majority were adults, (average 61.7 years), brown, male, low educational level, economically active, all classified as low income. Among the forms of the disease, the most prevalent was boderline with multibacillary operational classification. The grade 0 disabilities predominated with 66.7%. The advanced age and the socioeconomic profile of the majority of the patients, constitute in greater risks to the health. Multibacillary predominance demonstrates the importance of early diagnosis and appropriate treatment for being more aggressive, which together with the reactions are important causes of physical incapacity, leading to absenteeism of work.A hansenÃase é uma doença infectocontagiosa causada pelo mycobacterium leprae e se manifesta principalmente através de sinais e sintomas dermatoneurológicos. O objetivo do estudo foi descrever o perfil clÃnico e epidemiológico dos portadores de hansenÃase cadastrados no centro clÃnico universitário. Foi elaborado um roteiro de entrevista para 33 pacientes referentes à s condições socioeconômicas, demográficas, ambientais e clÃnicas. A maioria era adultos, (média de 61,7 anos), pardos, sexo masculino, baixa escolaridade, economicamente ativos, todos classificados como baixa renda. Entre as formas da doença, a mais prevalente foi a dimorfa com a classificação operacional multibacilar. A incapacidade fÃsica de grau 0 predominou com 66,7%. Dentre os fatores que proporcionam maior risco à saúde, inclui-se a idade avançada e a baixa condição socioeconômica. A predominância multibacilar demonstra a importância do diagnóstico precoce e tratamento adequado por se tratar de caráter mais agressivos, que juntamente com as reações são importantes causas de incapacidade fÃsica, acarretando absenteÃsmo do trabalho
Constructing resilience through security and surveillance: The politics, practices and tensions of security-driven resilience
This article illuminates how, since 9/11, security policy has gradually become more central to a range of resilience discourses and practices. As this process draws a wider range of security infrastructures, organizations and approaches into the enactment of resilience, security practices are enabled through more palatable and legitimizing discourses of resilience. This article charts the emergence and proliferation of security-driven resilience logics, deployed at different spatial scales, which exist in tension with each other. We exemplify such tensions in practice through a detailed case study from Birmingham, UK: ‘Project Champion’ an attempt to install over 200 high-resolution surveillance cameras, often invisibly, around neighbourhoods with a predominantly Muslim population. Here, practices of security-driven resilience came into conflict with other policy priorities focused upon community-centred social cohesion, posing a series of questions about social control, surveillance and the ability of national agencies to construct community resilience in local areas amidst state attempts to label the same spaces as ‘dangerous’. It is argued that security-driven logics of resilience generate conflicts in how resilience is operationalized, and produce and reproduce new hierarchical arrangements which, in turn, may work to subvert some of the founding aspirations and principles of resilience logic itself

Anticipatory governance for social-ecological resilience
Anticipation is increasingly central to urgent contemporary debates, from climate change to the global economic crisis. Anticipatory practices are coming to the forefront of political, organizational, and citizens’ society. Research into anticipation, however, has not kept pace with public demand for insights into anticipatory practices, their risks and uses. Where research exists, it is deeply fragmented. This paper seeks to identify how anticipation is defined and understood in the literature and to explore the role of anticipatory practice to address individual, social, and global challenges. We use a resilience lens to examine these questions. We illustrate how varying forms of anticipatory governance are enhanced by multi-scale regional networks and technologies and by the agency of individuals, drawing from an empirical case study on regional water governance of Malaren, Sweden. Finally, we discuss how an anticipatory approach can inform adaptive institutions, decision making, strategy formation, and societal resilience
