    There has been for some time a widespread view that anyone under investigation with regard to suspected wrongdoing should be entitled to anonymity prior to charge. Yet no attempt has been made to legislate. The matter is governed currently by the recently developed law of privacy, deriving from such cases as Campbell v MGN Ltd and culminating in the decision of the Supreme Court in ZXC v Bloomberg LP. It seems to be accepted, not only in England but under human rights law generally, that such information should be regarded as "private". This has not seriously been undermined in any of the leading cases. There is surely a serious question as to whether a suspect does indeed have a reasonable expectation that there should be such a blanket over his or her identity. This information is not purely personal. It relates to suspected wrongdoing – information which legitimately concerns not only any individual under suspicion but also, for example, "victims" and no doubt other fellow citizens interested in getting to the truth and in the administration of justice. Naturally, if a suspect's name leaks out, that individual's reputation may be seriously damaged. Some take the view that compensation should be recoverable specifically for injury to reputation – even though the claim would not be brought in defamation. Yet privacy and libel are distinct causes of action with different purposes to fulfil. If damages are to be sought to vindicate reputation, it is hard to see why a defendant should not have available the traditional defences and other principles applying in defamation. If a claimant wishes to demonstrate that the allegations are false, as well as intrusive, why should he not be subject to the same disciplines and risks as one who sues in libel

    Virtual Battlespace Scenario Encoding for Reuse, Phase I Report

    The United States Army and United States Marine Corps employ the Virtual Battlespace 2 (VBS2) commercial game for small unit training. Each service has significant investment in training scenarios constructed using VBS2 tools and conforming to the vendor's particular data formats. To move toward improved interoperability, to gain greater fiscal flexibility in addressing the statutory intent for open competition and affordability, and to protect the investment made in models, terrain, and other elements of training scenarios that are separate and distinct from the virtual and gaming environments in which the simulation executes, open standards need to be applied in place of proprietary commercial off-the-shelf architectures. In the current ( and foreseeable) environment of constrained budgets, it is ever more critical that the services protect and enhance their investments in simulation systems used for training and other purposes. Expanding capabilities for open scenario interchange will improve scenario reuse while creating greater opportunities for simulation data interchange and open competition for future gaming capabilities. The Extensible Markup Language (XML) is a wide-spread approach to describing data format and content to support efficient data processing and data interchange across systems. This report describes initial application of XML technologies to the representation of VBS2 scenario data, demonstrating feasibility for the capture and exchange of VBS2 scenario data. The report provides a plan of action for a follow-on phase of the effort to expand the representation and for use with other XML-based standards, such as the Military Scenario Definition Language (MSDL), to create opportunities for broader interchange of scenario data across a variety of combat simulations.Commander, Marine Corps Systems Command (DC SIAT)Marine Corps Systems Command, Modeling and Simulation OrganizationApproved for public release; distribution is unlimited

    Prenatal Diagnosis of Oculocutaneous Albinism by Electron Microscopy of Fetal Skin

    Oculocutaneous albinism was diagnosed prenatally by electron microscopic examination of fetal skin samples taken during fetoscopy at 20 weeks of gestation. Melanosome development in hair bulb melanocytes progressed no further than stage II, indicating a lack of melanin synthesis. In 4 age-matched control fetuses, numerous stage IV melanosomes, signifying active melanin synthesis, were identified. The diagnosis was confirmed after the pregnancy was terminated at 22 weeks. Examination of the fetal eye showed absence of pigment in the retinal epithelium and uvea at a stage when ocular melanogenesis would normally be active. This study shows that oculocutaneous albinism can be detected in the second trimester using similar techniques to those employed in the prenatal diagnosis of epidermolysis bullosa and ichthyosis

    Rapid Prenatal Diagnosis and Exclusion of Epidermolysis Bullosa Using Novel Antibody Probes

    Get PDF
    Prenatal diagnosis of recessive dystrophic epidermolysis bullosa was successfully achieved at 19 weeks' gestation by indirect immunofluorescence examination of a fetal skin biopsy sample using the monoclonal antibody LH 7:2. The abortus displayed marked blistering and the diagnosis was confirmed by transmission electron microscopy (TEM). In 3 further pregnancies at risk for lethal junctional epidermolysis bullosa the diagnosis was excluded using the polyclonal antibody AA3. In all these studies the results were available within 4h of receiving the samples. These new techniques offer a quick and simple alternative to TEM for midtrimester prenatal diagnosis of 2 severe recessive forms of epidermolysis bullosa

    Inherited epidermolysis bullosa

    Inherited epidermolysis bullosa (EB) encompasses a number of disorders characterized by recurrent blister formation as the result of structural fragility within the skin and selected other tissues. All types and subtypes of EB are rare; the overall incidence and prevalence of the disease within the United States is approximately 19 per one million live births and 8 per one million population, respectively. Clinical manifestations range widely, from localized blistering of the hands and feet to generalized blistering of the skin and oral cavity, and injury to many internal organs. Each EB subtype is known to arise from mutations within the genes encoding for several different proteins, each of which is intimately involved in the maintenance of keratinocyte structural stability or adhesion of the keratinocyte to the underlying dermis. EB is best diagnosed and subclassified by the collective findings obtained via detailed personal and family history, in concert with the results of immunofluorescence antigenic mapping, transmission electron microscopy, and in some cases, by DNA analysis. Optimal patient management requires a multidisciplinary approach, and revolves around the protection of susceptible tissues against trauma, use of sophisticated wound care dressings, aggressive nutritional support, and early medical or surgical interventions to correct whenever possible the extracutaneous complications. Prognosis varies considerably and is based on both EB subtype and the overall health of the patient

    Abundances of Iron-Binding Photosynthetic and Nitrogen-Fixing Proteins of Trichodesmium Both in Culture and In Situ from the North Atlantic

    Marine cyanobacteria of the genus Trichodesmium occur throughout the oligotrophic tropical and subtropical oceans, where they can dominate the diazotrophic community in regions with high inputs of the trace metal iron (Fe). Iron is necessary for the functionality of enzymes involved in the processes of both photosynthesis and nitrogen fixation. We combined laboratory and field-based quantifications of the absolute concentrations of key enzymes involved in both photosynthesis and nitrogen fixation to determine how Trichodesmium allocates resources to these processes. We determined that protein level responses of Trichodesmium to iron-starvation involve down-regulation of the nitrogen fixation apparatus. In contrast, the photosynthetic apparatus is largely maintained, although re-arrangements do occur, including accumulation of the iron-stress-induced chlorophyll-binding protein IsiA. Data from natural populations of Trichodesmium spp. collected in the North Atlantic demonstrated a protein profile similar to iron-starved Trichodesmium in culture, suggestive of acclimation towards a minimal iron requirement even within an oceanic region receiving a high iron-flux. Estimates of cellular metabolic iron requirements are consistent with the availability of this trace metal playing a major role in restricting the biomass and activity of Trichodesmium throughout much of the subtropical ocean

    Trace elements at the intersection of marine biological and geochemical evolution

    Get PDF
    Life requires a wide variety of bioessential trace elements to act as structural components and reactive centers in metalloenzymes. These requirements differ between organisms and have evolved over geological time, likely guided in some part by environmental conditions. Until recently, most of what was understood regarding trace element concentrations in the Precambrian oceans was inferred by extrapolation, geochemical modeling, and/or genomic studies. However, in the past decade, the increasing availability of trace element and isotopic data for sedimentary rocks of all ages has yielded new, and potentially more direct, insights into secular changes in seawater composition – and ultimately the evolution of the marine biosphere. Compiled records of many bioessential trace elements (including Ni, Mo, P, Zn, Co, Cr, Se, and I) provide new insight into how trace element abundance in Earth's ancient oceans may have been linked to biological evolution. Several of these trace elements display redox-sensitive behavior, while others are redox-sensitive but not bioessential (e.g., Cr, U). Their temporal trends in sedimentary archives provide useful constraints on changes in atmosphere-ocean redox conditions that are linked to biological evolution, for example, the activity of oxygen-producing, photosynthetic cyanobacteria. In this review, we summarize available Precambrian trace element proxy data, and discuss how temporal trends in the seawater concentrations of specific trace elements may be linked to the evolution of both simple and complex life. We also examine several biologically relevant and/or redox-sensitive trace elements that have yet to be fully examined in the sedimentary rock record (e.g., Cu, Cd, W) and suggest several directions for future studies
