    This research note presents the findings of an appraisal of the archives of Lloyd's Register recently undertaken by researchers from Blaydes Maritime Centre at the University of Hull. Funded by the Lloyd's Register Foundation, the aim of this project was to assess the character, extent and evidential quality of a rich yet underutilized assemblage of records relating to shipping and vessel safety from the late eighteenth century. After discussing material generated by the organization's management committees, ship classification process and labour deployment, the research note concludes with a discussion of current and future reader access to this large, historically significant and dynamically evolving collection of primary source materials

    Dryland tree data for the Southwest region of Madagascar: alpha-level data can support policy decisions for conserving and restoring ecosystems of arid and semiarid regions

    We present an eco-geographical dataset of the 355 tree species (1 56 genera, 55 families) found in the driest coastal portion of the spiny forest-thickets of southwestern Madagascar. This coastal strip harbors one of the richest and most endangered dryland tree floras in the world, both in terms of overall species diversity and of endemism. After describing the biophysical and socio-economic setting of this semiarid coastal region, we discuss this region’s diverse and rich tree flora in the context of the recent expansion of the protected area network in Madagascar and the growing engagement and commitment to ecological restoration. Our database, DTsMada (short for Desert Trees of Madagascar), is part of a larger ‘work-in-progress’, namely an eco-geographical database on desert and dryland trees of the world. DTsMada draws heavily on the Catalogue of the Vascular Plants of Madagascar (MadCat) project, in which floristic, ecological and endemism parameters are compiled, together with available conservation status assessments based on IUCN Red List criteria. Both are projects within the plant systematics database, TropicosÂź, developed at Missouri Botanical Garden and maintained on the Garden’s website. To highlight the need for greater study of the interactions between biological, bioclimatic, and anthropogenic determinants of current and potentially changing biogeographical patterns and community dynamics in the tree strata of vegetation in the study area, we consider four contrasting groups of native trees: Adansonia spp. (Malvaceae), Pachypodium spp. (Apocynaceae), Baudouinia spp. (Fabaceae), and all 1 1 species in the 4 genera of Didiereaceae in Madagascar. We discuss DTsMada as a prototype dataset of alpha level information vital for effective conservation, landscape planning, sustainable use and management, and ecological restoration of degraded arid and semiarid ecosystems, in Madagascar and elsewhere. RÉSUMÉNous prĂ©sentons un ensemble de donnĂ©es Ă©co-gĂ©ographiques sur les 355 espĂšces d’arbres (1 56 genres, 55 familles) prĂ©sentes dans les fourrĂ©s et forĂȘts Ă©pineux de la frange cĂŽtiĂšre aride et semiaride du Sud-ouest de Madagascar. Cette rĂ©gion possĂšde un des assemblages d’arbres de climat sec les plus riches (en termes de diversitĂ© spĂ©cifique et d’endĂ©misme), et les plus menacĂ©s au monde. AprĂšs une description du cadre biophysique et de la situation socio-Ă©conomique de cette rĂ©gion, nous prĂ©sentons cette flore rĂ©gionale dans le contexte de la rĂ©cente expansion du rĂ©seau de des aires protĂ©gĂ©es de Madagascar et de l’engagement croissant dans le domaine de la restauration Ă©cologique. Notre base de donnĂ©es DTsMada (raccourci de «d Desert Trees - Madagascar d », en anglais) s’inscrit dans le cadre d’une base de donnĂ©es éco-gĂ©ographique plus large que nous dĂ©veloppons, regroupant les espĂšces d’arbres des rĂ©gions arides et semiarides du monde entier, avec un accent particulier mis sur leur utilisation dans la conservation, gestion et restauration Ă©cologique. Nombre des informations prĂ©sentĂ©es dans DTsMada proviennent du projet MadCat (Catalogue des plantes vasculaires de Madagascar) qui regroupe des donnĂ©es floristiques et Ă©cologiques, et les statuts d’endĂ©misme et de conservation des espĂšces vĂ©gĂ©tales, basĂ©s sur les critĂšres de l’UICN. Ces deux projets font partie de la base de donnĂ©es taxonomique TropicosÂź, du Jardin Botanique du Missouri. Pour souligner le besoin de disposer de plus d’études pour comprendre d : les interactions entre les facteurs biologiques, bioclimatiques et anthropiques qui affectent la biogĂ©ographie et les dynamiques des communautĂ©s dans les strates arborĂ©es de la vĂ©gĂ©tation dans la rĂ©gion Ă©tudiĂ©e, qu’il s’agisse de la situation actuelle ou celle d’un futur qui sera Ă©ventuellement modifiĂ©, nous considĂ©rons quatre groupes bien diffĂ©rents d’espĂšces d’arbres indigĂšnesd : Adansonia spp. (Malvaceae), Pachypodium spp. (Apocynaceae), Baudouinia spp. (Fabaceae) et les 1 1 espĂšces dans les 4 genres de la famille des Didiereaceae du Sud-ouest de Madagascar. Nous traitons DTsMada comme prototype d’une base de donnĂ©es de niveau alpha, vitales pour la conservation, la planification, le dĂ©veloppement durable, la gestion et la restauration Ă©cologique des Ă©cosystĂšmes arides et semiarides de Madagascar et d’ailleurs

    A particularly interesting panel, this one examines media access, pretrial publicity, and the presumption of innocence, comparing the laws and practices in the United States to those in several European countries and Canada. The panelists speak to the national laws of continental Europe and case law of the European Court of Human Rights, law and practices in the United Kingdom, Canada, and the United States. Apparent differences emerge in both trial procedures and media actions and expectations in these various countries. Questions/themes/discussion topics Comparing U.S. law to the law of other countries concerning media access to trials, pretrial information that might prejudice a juror, and the presumption of innocence What restrictions on the press do other countries employ to ensure that defendants get a fair trial? What restrictions do other countries employ to ensure that the reputation of innocent defendants are not irreparably damaged in the course of legal proceedings? Should freedom of the press be reexamined under a modern media lens? What are the differences between English law concerning journalist liability and U.S. law as defined by New York Times v. Sullivan? The effect of Naomi Campbell\u27s court case on UK law Difference between jury selection in the U.S. and Canad

    The distribution of biodiversity richness in the tropics

    Get PDF
    We compare the numbers of vascular plant species in the three major tropical areas. The Afrotropical Region (Africa south of the Sahara Desert plus Madagascar), roughly equal in size to the Latin American Region (Mexico southward), has only 56,451 recorded species (about 170 being added annually), as compared with 118,308 recorded species (about 750 being added annually) in Latin America. Southeast Asia, only a quarter the size of the other two tropical areas, has approximately 50,000 recorded species, with an average of 364 being added annually. Thus, Tropical Asia is likely to be proportionately richest in plant diversity, and for biodiversity in general, for its size. In the animal groups we reviewed, the patterns of species diversity were mostly similar except for mammals and butterflies. Judged from these relationships, Latin America may be home to at least a third of global biodiversity

    Accelerated Wound Healing in Minipigs by On-Site Production and Delivery of CXCL12 by Transformed Lactic Acid Bacteria

    Non-healing wounds are a growing medical problem and result in considerable suffering. The lack of pharmaceutical treatment options reflects the multistep wound healing process, and the complexity of both translation and assessment of treatment efficacy. We previously demonstrated accelerated healing of full-thickness wounds in mice following topical application of the probiotic bacteria Limosilactobacillus reuteri R2LC transformed to express CXCL12. In this study, safety and biological effects of a freeze-dried formulation of CXCL12-producing L. reuteri (ILP100) were investigated in induced full-thickness wounds in minipigs, and different wound healing evaluation methods (macroscopic, planimetry, 2D-photographs, 3D-scanning, ultrasound) were compared. We found that treatment with ILP100 was safe and accelerated healing, as granulation tissue filled wound cavities 1 day faster in treated compared to untreated/placebo-treated wounds. Furthermore, evaluation using planimetry resulted in 1.5 days faster healing than using 2D photographs of the same wounds, whereas the areas measured using 2D photographs were smaller compared to those obtained from 3D scans accounting for surface curvatures, whereas ultrasound imaging enabled detailed detection of thin epithelial layers. In conclusion, topical administration of the drug candidate ILP100 warrants further clinical development as it was proven to be safe and to accelerate healing using different evaluation methods in minipigs

    Quantifying uncertainty in land cover mappings: an adaptive approach to sampling reference data using Bayesian inference

    Get PDF
    Mappings play an important role in environmental science applications by allowing practitioners to monitor changes at national and global scales. Over the last decade, it has become increasingly popular to use satellite imagery data and machine learning techniques (MLTs) to construct such maps. Given the black-box nature of many of these MLTs though, quantifying uncertainty in these maps often relies on sampling reference data under stricter conditions. However, practical constraints can sampling such data expensive, which forces stakeholders to make a trade-off between the degree of uncertainty in predictions and the costs of collecting appropriately sampled reference data. Furthermore, quantifying any trade-off is often difficult, as it will depend on many interdependent factors that cannot be fully understood until more data is collected. This paper investigates how a combination of Bayesian inference and an adaptive approach to sampling reference data can offer a generalizable way of managing such trade-offs. The approach is illustrated and evaluated using a woodland mapping of England as a case study in which reference data is collected under constraints motivated by COVID-19 travel restrictions. The key findings of this paper are as follows: (a) an adaptive approach to sampling reference data allows an informed approach when quantifying this trade-off; and (b) Bayesian inference is naturally suited to adaptive sampling and can make use of Monte Carlo methods when dealing with more advanced problems and analytical techniques

    Nomenclatural changes in Coleus and Plectranthus (Lamiaceae): a tale of more than two genera

    Get PDF
    A synopsis of the genera Coleus Lour, Equilabium A.J.Paton, Mwany. & Culham and Plectranthus L’HĂ©r. (Lamiaceae, Tribe Ocimeae, Subtribe Plecranthinae) is presented. Generic delimitation follows a recently published molecular phylogeny which identified Coleus as the sister of the remaining genera of Subtribe Plectranthinae; Plectranthus as sister to Tetradenia Benth. and Thorncroftia N.E.Br., and a separate phylogenetically distinct genus Equilabium comprising species previously placed in Plectranthus. In this treatment, 294 species of Coleus, 42 of Equilabium, and 72 of Plectranthus are recognized. All but one of the combinations in Equilabium are new as only the genus and type species have been previously published. Two-hundred and twelve names are changed to combinations in Coleus from Plectranthus, Pycnostachys Hook. and Anisochilus Benth

    Growing old in a new estate: Establishing new social networks in retirement

    Get PDF
    The benefits of a strong proximal social network for people as they advance in age are well documented, but the continuation or development of social networks may be challenged when people relocate to a new home on retirement. This paper explores the personal network development of older residents who have moved to a new suburban (but not age-specific) residential development in a general urban setting. Drawing on a case study of a new outer-suburban ‘master planned estate ’ in Brisbane, Queensland, the findings from interviews with 51 older residents and participant observations of a community group are presented. The study suggests that a traditional ideal of unreflexive community of place was an unreliable source of durable social bonds in contemporary fragmented and mobile social conditions, where the proximity of family members, durability of tenure and strong neighbourly ties are not inevitable. One successful resolution was found in a group of older residents who through exercising agency had joined a group the sole focus of which was social companionship. The theoretical bases of this type of group are discussed and its relevance is examined for retirees who have chosen to live in a residential environment for lifestyle and amenity reasons, away from their lifelong social networks
