    2005-07-01

    This paper presented case histories of swelling packer technology open hole innovations. Challenges such as fluid flow management and the restriction of solids entering the well bore were discussed. Other challenges included the need to reduce well construction costs, long-term reliability, production optimization methods and positive economic returns. In order to simplify production methods, minimize pay zone damage and eliminate moving parts, it is advisable to return to the simpler open hole well-bore method. Zonal isolation issues were discussed. The role of oil swelling packer was described with reference to its flexibility attributes such as the fact that rubber swells in hydrocarbons, activates in oil but not pure water, and creates an effective seal in open hole. Swell packer for oil-based mud was examined, along with details of successful applications. Functionality issues were discussed. The advantages of swell pack for oil-based mud is that it is rugged, self-repairing and has no environmental impact. It also has a good track record and is more flexible than concrete, more durable than Hydrogenated Nitrile Butadiene Rubber (HNBR) and regains integrity after failure. Various well construction advances, completion advances and global installations were discussed. Reservoir, well construction and completion challenges were reviewed. Economic challenges were discussed. Various features of the Constrictor swell packer, which enables annular fluid flow management, were presented. The Oil Selector, a product that enables automatic water control, was also reviewed. 7 figs.

By looking at a recent transfer of technology this reciprocal exchange is elaborated by considering the cultural or contextual influence in the adaptation of technology. In this connection the notion of technological style is revisited...... by questioning whether it pays due attention to the non-technical factors of the process? In order to compensate for the deficiencies of the technological style as a sensitizing device the concept of sociotechnical style is introduced – a concept more in tune with resent research in technology studies....

    This report discusses the need for industry/government cooperation in developing new semiconductor technology. In order to increase memory density of chips from 1M bit, it is necessary to use a process other than optical lithography for production. The technique considered here is x-ray lithography. Industry is currently found to be unwilling or unable to finance research into this technology. If US industry is to remain competitive in the world semiconductor market, it is concluded that the government must cooperate and support work in this area. 16 refs. (JDH)

  9. Understanding invasion history and predicting invasive niches using genetic sequencing technology in Australia: case studies from Cucurbitaceae and Boraginaceae

    Part of the challenge in dealing with invasive plant species is that they seldom represent a uniform, static entity. Often, an accurate understanding of the history of plant introduction and knowledge of the real levels of genetic diversity present in species and populations of importance is lacking. Currently, the role of genetic diversity in promoting the successful establishment of invasive plants is not well defined. Genetic profiling of invasive plants should enhance our understanding of the dynamics of colonization in the invaded range. Recent advances in DNA sequencing technology have greatly facilitated the rapid and complete assessment of plant population genetics. Here, we apply our current understanding of the genetics and ecophysiology of plant invasions to recent work on Australian plant invaders from the Cucurbitaceae and Boraginaceae. The Cucurbitaceae study showed that both prickly paddy melon (Cucumis myriocarpus) and camel melon (Citrullus lanatus) were represented by only a single genotype in Australia, implying that each was probably introduced as a single introduction event. In contrast, a third invasive melon, Citrullus colocynthis, possessed a moderate level of genetic diversity in Australia and was potentially introduced to the continent at least twice. The Boraginaceae study demonstrated the value of comparing two similar congeneric species; one, Echium plantagineum, is highly invasive and genetically diverse, whereas the other, Echium vulgare, exhibits less genetic diversity and occupies a more limited ecological niche. Sequence analysis provided precise identification of invasive plant species, as well as information on genetic diversity and phylogeographic history. Improved sequencing technologies will continue to allow greater resolution of genetic relationships among invasive plant populations, thereby potentially improving our ability to predict the impact of these relationships upon future spread and better manage invaders possessing

    Liner hangers are used in deep drilling operations to eliminate the need for full casing strings. However, conventional liner-hanger system do not always permit tool rotation, and liner-hanger failures can result in the complete loss of the wellbore. This study discussed an expandable liner hanger designed to withstand aggressive reaming as well as drilling to depths. Three case histories of wells located in southern Venezuela were used to compare the use of traditional and expandable liner hanger systems. The studies considered liner weight, and the pressure differentials caused by the use of positive seals. The study showed that conventional liner systems are not suited to the extreme environments of the Venezuelan heavy oil reserves. Multiple leak paths were observed. The expandable liner system provided a gas-tight seal, improved flow paths, and reduced the need for remedial cement jobs. It was concluded that use of the expandable systems also increased worker safety. 6 refs., 13 figs.

    2002-12-01

    This paper begins with the history of electrochromism, first discovered in the 1880's. The physics, electrochemistry, device design and materials are covered. The science of electrochromism involves the coloration of a variety of metal oxides, organics and polymers. Dual ion and electron intercalation is used to color and bleach electrochromic materials. Considerable science has been undertaken to make devices that resemble thin film transparent batteries in their structure. A number of materials have been developed to make layers for electrochromic devices. Applications for electrochromics include low information content displays, such as banner displays, smart windows and mirrors for automotive applications. Several companies throughout the world are developing dynamic glazing. Switchable glazing for building and vehicle application is very attractive for energy and light management. From the standpoint of materials much research and development in electrochromics focuses on the development or improvement of materials with ionic and electronic properties. Much of the work on electrochromics draws on the vast knowledge developed for advanced batteries. National Laboratory and university groups are researching new materials and processes to improve electrochromic materials. Also, much industrial work is directed towards deposition and fabrication processes for glass and possibly plastic that can make electrochromics cost effective. Plastic can yield both flexibility and weight savings for many applications. Although plastics are permeable, outgas and require lower processing temperatures, they can be more universally applied. Some developments in plastics may come from OLED sealing technology. Comparisons are made between the properties of electrochromics and other switchable technologies. Technology comparisons are made between suspended particles, polymer dispersed liquid crystals, themotropics and gas-chromics.

    2017-03-01

    Fundamental knowledge of natural history is lacking in many western societies, as demonstrated by its absence in school science curricula. And yet, to meet local and global challenges such as environmental degradation, biodiversity loss and climate change, we need to better understand the living and non-living parts of the natural world. Many have argued passionately for an increased understanding of natural history; others have developed successful pedagogical programmes for applying knowledge of natural history in environmental initiatives. In joining wider calls, we choose here to focus on the educational value afforded by understanding the epistemological bases of natural history and its particular forms of reasoning. We also briefly discuss the ways in which an education in natural history provides the foundation for environmental and social justice efforts that directly affect the lives of young people and their communities. We end by highlighting the ease by which natural history may be incorporated in learning opportunities both in and outside of the classroom.

  3. Visual cultures in science and technology a comparative history

    CERN Document Server

    Hentschel, Klaus

    2014-01-01

    This book attempts a synthesis. It delves into the rich reservoir of case studies on visual representations in scientific and technological practice that have been accumulated over the past couple of decades by historians, sociologists, and philosophers of science. The main aim is thus located on the meta-level. It adopts an integrative view of recurrently noted general features of visual cultures in science and technology, something hitherto unachieved and believed by many to be a mission impossible. By systematic comparison of numerous case studies, the purview broadens away from myopic microanalysis in search of overriding patterns. The many different disciplines and research areas involved encompass mathematics, technology, natural history, medicine, the geosciences, astronomy, chemistry, and physics. The chosen examples span the period from the Renaissance to the late 20th century. Some pioneers of new visual cultures are portrayed, along with the modes of skill transfer and development. The broad range ...

    Case histories are described in which measurable improvements in the cabin noise environments of the Bell 214B, 206B, and 222 were realized. These case histories trace the noise control efforts followed in each vehicle. Among the design approaches considered, the addition of a fluid pulsation damper in a hydraulic system and the installation of elastomeric engine mounts are highlighted. It is concluded that substantial weight savings result when the major interior noise sources are controlled by design, both in altering the noise producing mechanism and interrupting the sound transmission paths.

  6. A Material History of Electroshock Therapy : Electroshock Technology in Europe until 1945.

    Science.gov (United States)

    Rzesnitzek, Lara; Lang, Sascha

    2016-09-01

    The article considers the history of electroshock therapy as a history of medical technology, professional cooperation and business competition. A variation of a history from below is intended; though not from the patients' perspective (Porter, Theory Soc 14:175-198, 1985), but with a focus on electrodes, circuitry and patents. Such a 'material history' of electroshock therapy reveals that the technical make-up of electroshock devices and what they were used for was relative to the changing interests of physicians, industrial companies and mental health politics; it makes an intriguing case for the Social Construction of Technology theory (Bijker et al., The social construction of technological systems: new directions in the sociology and history of technology. MIT Press, Cambridge, MA, 1987).

  10. The strange case of the Freudian case history: the role of long case histories in the development of psychoanalysis.

    Science.gov (United States)

    Sealey, Anne

    2011-01-01

    Sigmund Freud's five long case histories have been the focus of seemingly endless fascination and criticism. This article examines how the long case-history genre developed and its impact on the professionalization of psychoanalysis. It argues that the long case histories, using a distinctive form that highlighted the peculiarities of psychoanalytic theory, served as exemplars in the discipline. In doing so, the article extends John Forrester's work on "thinking in cases" to show the practical implications of that style of reasoning. The article illustrates how the form disappeared once the theoretical basis of the movement was set. The genre never became institutionalized, although the content of the five long case histories did, because of Freud's accepted role as theoretician of psychoanalysis.

    2015-01-01

    The incorporation of virtual engineering into dentistry and the digitization of information are providing new perspectives and innovative alternatives for dental treatment modalities. The use of digital surface scanners with surgical planning software allows for the combination of the radiographic, prosthetic, surgical, and laboratory fields under a common virtual scenario, permitting complete digital treatment planning. In this article, the authors present a clinical case in which a guided implant surgery was performed based on a complete digital surgical plan combining the information from a cone beam computed tomography scan and the virtual simulation obtained from the 3Shape TRIOS intraoral surface scanner. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. A surgical guide was obtained by a 3D printer, and the surgical procedure was done using the Biohorizons Guided Surgery Kit and its protocol.

  12. [Psychiatric case history of Vincent van Gogh].

    Science.gov (United States)

    van Meekeren, E

    2000-12-23

    Much has been written about Vincent van Gogh's pathological condition. Most authors base their various diagnoses on the symptoms he exhibited in the last years of his life. However, Van Gogh during a much longer part of his life displayed symptoms best consistent with a borderline (personality) disorder: impulsivity, variable moods, self-destructive behaviour, fear of abandonment, an unbalanced self-image, authority conflicts and other complicated relationships. The precipitating element disturbing Vincent's psychic balance--delicate in any case due to a positive family history, malnutrition, intoxication and exhaustion and the borderline disorder--may have been his being deserted by his friend Gauguin. He (also) developed an organic psychosyndrome with psychotic and epileptic elements. The stress (due to social isolation, by his being a psychiatric patient, and by poor prospects), the intoxication going on outside the hospitals and especially also the problems relating to his brother Theo caused a downward spiral culminating in suicide.

  13. Helicons, History, High Technology and Heliacs

    Science.gov (United States)

    Boswell, Rod

    1998-11-01

    Helicon waves depend basically on the Hall effect and propagate between the ion and electron gyro frequencies: they are whistlers masquerading under another name hence their history goes back to the great war and subsequently involved such people as Appleton, Hartree and Storey. Considerable experimental and theoretical research was carried out on linear propagation during the 1960's and at the end of the decade it was discovered that the wave could actually heat the plasma electrons and increase the ionisation rate considerably. Nothing much happened during the 1970's but in the early 1980's it was realised that this high density source could be used for processing thin films and an increasing number of papers were published, which continues to this day. The first experiments on using helicons to create and heat toroidal plasmas were carried out at the end of the 1980's in a small heliac. Recent experiments with helicon excitation in the large heliac H1 at the ANU have shown that the ion temperature increases with the wave power. This mystery is being actively investigated.

  14. History of healthcare technology assessment in Japan.

    Science.gov (United States)

    Hisashige, Akinori

    2009-07-01

    There has been a rapid growth of healthcare technology assessment (HTA) activities among health service researchers and physicians in Japan in the younger generation since the mid-1980s. HTA has become visible since the Ministry of Health, Labor, and Welfare (MHLW) set up the several committees related to HTA in the late 1990s. The MHLW had to participate in regulatory and administrative reform, coping with the serious economic stagnation since 1991, following the economic recession in the 1980s. However, HTA has not been developed as expected. The most important failure is that the application of HTA to health policy has been neglected by the MHLW. Only application to clinical practice has been implemented by developing evidence-based clinical practice guidelines. The MHLW had the main aim of containing costs by reducing excess or useless healthcare services through guidelines, rather than to implement a radical reform. Without a central organization for HTA, several researchers have still continued to do HTA studies, but most researchers and physicians promoting HTA have been moved into diverse related areas. Ultimately, increasing efficiency may be the only way of reconciling rising demands for health care with public financing constraints. Therefore, the reconsideration and reorganization of HTA, which covers not only healthcare services but also the healthcare system as a whole, is becoming an urgent matter for healthcare reform.

  15. History and Technology of Terra Preta Sanitation

    Directory of Open Access Journals (Sweden)

    Sabino De Gisi

    2014-03-01

    Full Text Available In order to reach the Millennium Development Goals for significantly reducing the number of people without access to adequate sanitation, new holistic concepts are needed focusing on economically feasible closed-loop ecological sanitation systems rather than on expensive end-of-pipe technologies. An analysis of a former civilization in the Amazon (nowadays Brazil highlights the possibility to close the loop with a more sustainable lifestyle integrating soil fertility, food security, waste management, water protection and sanitation, renewable energy. Terra Preta do Indio is the anthropogenic black soil produced by ancient cultures through the conversion of bio-waste, fecal matter and charcoal into long-term fertile soils. These soils have maintained high amounts of organic carbon several thousand years after they were abandoned. Deriving from these concepts, Terra Preta Sanitation (TPS has been re-developed and adopted. TPS includes urine diversion, addition of a charcoal mixture and is based on lactic-acid-fermentation with subsequent vermicomposting. Lacto-fermentation is a biological anaerobic process that generates a pre-stabilization of the mixture. The main advantage of lacto-fermentation is that no gas and no odor is produced. What makes it particularly interesting for in-house systems even in urban areas. Instead, vermicomposting is an aerobic decomposition process of the pre-digested materials by the combined action of earthworms and microorganisms. It transforms the carbon and nutrients into the deep black, fertile and stable soil that can be utilized in agriculture. No water, ventilation or external energy is required. Starting from ancient Amazonian civilizations traditional knowledge, the aim of this work is to present TPS systems adopted nowadays.

    Science.gov (United States)

    Rybach, L.; Muffler, L. J. P.

    The classification of geothermal systems is considered along with the geophysical and geochemical signatures of geothermal systems, aspects of conductive heat transfer and regional heat flow, and geothermal anomalies and their plate tectonic framework. An investigation of convective heat and mass transfer in hydrothermal systems is conducted, taking into account the mathematical modelling of hydrothermal systems, aspects of idealized convective heat and mass transport, plausible models of geothermal reservoirs, and preproduction models of hydrothermal systems. Attention is given to the prospecting for geothermal resources, the application of water geochemistry to geothermal exploration and reservoir engineering, heat extraction from geothermal reservoirs, questions of geothermal resource assessment, and environmental aspects of geothermal energy development. A description is presented of a number of case histories, taking into account the low enthalpy geothermal resource of the Pannonian Basin in Hungary, the Krafla geothermal field in Northeast Iceland, the geothermal system of the Jemez Mountains in New Mexico, and extraction-reinjection at the Ahuachapan geothermal field in El Salvador.

Drawing on a range of hitherto and marginalised examples from the world of visual representation and the work of key theorists and thinkers, such as Latour, de Certeau, McLuhan and Barthes, David Tomas offers a disarticulated and deviant view of the relationship between archaic and new representations, imaging technologies and media induced experience. Rejecting the possibility of absolute forms of knowledge, Tomas shows how new media technologies have ch

    2007-08-01

    Full Text Available Blogging is a twenty-first century phenomenon that has heralded an age where ordinary people can make their voices heard in the public sphere of the Internet. This article explores blogging as a form of popular history making; the blog as a public history document; and how blogging is transforming the nature of public history and practice of history making in Singapore. An analysis of two Singapore ‘historical’ blogs illustrates how blogging is building a foundation for a more participatory historical society in the island nation. At the same time, the case studies also demonstrate the limitations of blogging and blogs in challenging official versions of history.

  1. Sketching together the modern histories of science, technology, and medicine.

    Pickstone, John V

    2011-03-01

    This essay explores ways to "write together" the awkwardly jointed histories of "science" and "me dicine"--but it also includes other "arts" (in the old sense) and technologies. It draws especially on the historiography of medicine, but I try to use terms that are applicable across all of science, technology, and medicine (STM). I stress the variety of knowledges and practices in play at any time and the ways in which the ensembles change. I focus on the various relations of "science" and "medicine," as they were understood for a succession of periods--from mainly agricultural societies, through industrial societies, to our biomedical present--trying to sketch a history that encompasses daily practices and understandings as well as major conceptual and technical innovations. The model is meant to facilitate inquiry across topics and across times, including those to come.

    This was a study of the history of the technological development of air conduction hearing aids, and a review of international literature on the subject. The technological evolution of amplification devices, from their origin to the present day, can be divided into seven distinct periods: the period of sound collectors, the period of hearing devices constructed from carbon, the period of vacuum tubes, the transistor period, the period of integrated circuits, the microprocessor period and the period of digital hearing instruments. Throughout these different stages, hearing instruments have progressively developed reaching their present state. The current era is itself undergoing constant development and change. With the introduction of new technologies, we expect that the rate of change will increase rapidly in the future.

  3. History of artificial cold, scientific, technological and cultural issues

    2014-01-01

    The history of artificial cold has been a rather intriguing interdisciplinary subject (physics, chemistry, technology, sociology, economics, anthropology, consumer studies) which despite some excellent monographs and research papers, has not been systematically exploited. It is a subject with all kinds of scientific, technological as well as cultural dimensions. For example, the common home refrigerator has brought about unimaginably deep changes to our everyday lives changing drastically eating habits and shopping mentalities. From the end of the 19th century to the beginning of the 21st, issues related to the production and exploitation of artificial cold have never stopped to provide us with an incredibly interesting set of phenomena, novel theoretical explanations, amazing possibilities concerning technological applications and all encompassing cultural repercussions. The discovery of the unexpected and “bizarre” phenomena of superconductivity and superfluidity, the necessity to incorporate macroscopi...

  6. Boundaries and audiences of national histories of science: insights from the history of science and technology of the Netherlands.

    Science.gov (United States)

    Homburg, Ernst

    2008-01-01

    The present paper traces the evolution of writing national-oriented histories of science and technology of the Netherlands. Several episodes are distinguished. A first wave of national histories of science and technology was written during the first decades of the 19th century. These histories had a wide scope, which included science, technology, the humanities and the arts. A second wave, which lasted from about 1865 to 1900, was strongly connected to the rise of the scientific professions. Its focus was on the sciences perse, and on the Dutch "Golden Age" of the 17th century. A third wave occurred during and shortly after the Second World War. Its focus was mainly on the "Second Golden Age" of Dutch science (1870-1910), and its major audience were young boys that were to be recruited to the sciences. The second part of the paper discusses the growing influence of "contextualization" in both the history of science and the history of technology from about 1975 onwards. As a result, local factors often received more attention in historical studies of science and technology than national influences. In 1985, Klaas van Berkel undertook a bold attempt to write a new synthesis of the history of Dutch science, but his approach was too strongly influenced by the three previous waves of national histories. From 1989 to 2003 two projects on the national history of technology resulted in 13 volumes on Dutch technology between 1800 and 1970. New research was initiated, and the issue of "national styles" in the development of technology received ample attention. In his conclusions the author points to lessons to be learned from economic history and the history of art, and he concludes with a plea for more historiographical discussion in the history of science and technology.

  7. Drug Discovery Case History: US Spelling

    Kufahl, Peter R.; Watterson, Lucas R.

    2015-01-01

    Introduction Globally, alcohol abuse and dependence are significant contributors to chronic disease and injury and are responsible for nearly 4% of all deaths annually. Acamprosate (Campral), one of only three pharmacological treatments approved for the treatment of alcohol dependence, has shown mixed efficacy in clinical trials in maintaining abstinence of detoxified alcoholics since studies began in the 1980’s. Yielding inconsistent results, these studies have prompted skepticism. Areas Covered Herein, the authors review the preclinical studies which have assessed the efficacy of acamprosate in various animal models of alcohol dependence and discuss the disparate findings from the major clinical trials. Moreover, the authors discuss the major limitations of these preclinical and clinical studies and offer explanations for the often contradictory findings. The article also looks at the importance of the calcium moiety that accompanies the salt form of acamprosate and its relevance to its activity. Expert opinion The recent discovery that large doses of calcium largely duplicate the effects of acamprosate in animal models has introduced a serious challenge to the widely-held functional association between this drug and the glutamate neurotransmission system. Future research on acamprosate or newer pharmacotherapeutics should consider assessing plasma and/or brain levels of calcium as a correlate or mediating factor in anti-relapse efficacy. Furthermore, preclinical research on acamprosate has thus far lacked animal models of chemical dependence on alcohol, and the testing of rodents with histories of alcohol intoxication and withdrawal is suggested.

    2014-09-01

    Performance advantages of the new digital technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities. The decision to move forward with funding usually hinges on demonstrating actual cost reductions that can be credited to budgets and thereby truly reduce O&M or capital costs. Technology enhancements, while enhancing work methods and making work more efficient, often fail to eliminate workload such that it changes overall staffing and material cost requirements. It is critical to demonstrate cost reductions or impacts on non-cost performance objectives in order for the business case to justify investment by nuclear operators. This Business Case Methodology approaches building a business case for a particular technology or suite of technologies by detailing how they impact an operator in one or more of the three following areas: Labor Costs, Non-Labor Costs, and Key Performance Indicators (KPIs). Key to those impacts will be identifying where the savings are “harvestable,” meaning they result in an actual reduction in headcount and/or cost. The report consists of a Digital Technology Business Case Methodology Guide and an accompanying spreadsheet workbook that will enable the user to develop a business case.

  15. Using History to Teach Mathematics: The Case of Logarithms

    Science.gov (United States)

    Panagiotou, Evangelos N.

    2011-01-01

    Many authors have discussed the question why we should use the history of mathematics to mathematics education. For example, Fauvel (For Learn Math, 11(2): 3-6, 1991) mentions at least fifteen arguments for applying the history of mathematics in teaching and learning mathematics. Knowing how to introduce history into mathematics lessons is a more difficult step. We found, however, that only a limited number of articles contain instructions on how to use the material, as opposed to numerous general articles suggesting the use of the history of mathematics as a didactical tool. The present article focuses on converting the history of logarithms into material appropriate for teaching students of 11th grade, without any knowledge of calculus. History uncovers that logarithms were invented prior of the exponential function and shows that the logarithms are not an arbitrary product, as is the case when we leap straight in the definition given in all modern textbooks, but they are a response to a problem. We describe step by step the historical evolution of the concept, in a way appropriate for use in class, until the definition of the logarithm as area under the hyperbola. Next, we present the formal development of the theory and define the exponential function. The teaching sequence has been successfully undertaken in two high school classrooms.

  16. Case history report on East Mesa and Cerro Prieto geothermal fields

    Energy Technology Data Exchange (ETDEWEB)

    Davis, DG.; Sanyal, S.K.

    1979-06-01

    Well log analysis as applied to the geothermal industry is one of the areas of technology in great need of further development. One means of improving log analysis technology is to study case histories of the past uses of log analysis as applied to specific fields. The project described in this report involved case history studies on two well-known geothermal areas in North America: the East Mesa field in California and the Cerro Prieto field in Mexico. Since there was considerably more pertinent material available on East Mesa, a major part of the effort on this project was devoted to studying the East Mesa field. One particular problem that first came to attention when studying the Cerro Prieto data was the difficulty in determining actual formation temperature at the time of logging. Since the temperature can have a significant effect on well log readings, an accurate temperature determination was considered to be important.

    2014-01-01

    The contemporary sexual medicine case history is grounded in the Biopsychosocial Model and its recognition that the past influences one's current interpretation of symptoms. However, the thread of this model can be found throughout the case studies of the early pioneers of sexology. These early investigators began with examinations of homosexual men, slowly moving toward awareness that male sexuality comprises a continuum, while striving to place sexual behavior in a biologic context. Their perspectives served to establish the groundwork for the emerging construct of sexuality and helped shape current methods for identification of sexual function concerns.

    Nattacia Dabescki

    2014-11-01

    Full Text Available As a process of transferring skills, knowledge, technologies, methods of manufacturing and facilities among organizations, the transfer of technology is instrumental for boosting the economy through creation of competitive products, new jobs and a better quality of life. The stagnant environment for technology transfers in Macedonia in the post-privatisation era is a result of a combination of factors. Among them is the outdated educational system that does not boost entrepreneurial spirit and innovation thinking. Main purpose of this paper is to examine the current status, conditions, anomalies and challenges for technology transfer in the Republic of Macedonia, as well as the potential for development and possibilities for improvement of the process. Through a lens of the technology transfer paradigm, this exploratory study will present a case in which the Foundation Business Start-up Centre in Macedonia, as a technology transfer agent provided links and cooperative platform for creation of new technologies and innovations within the local SME ecosystem. The focus will be on a couple of initiatives for technology development and transfer in a domestic context. Results from the process of implementation of these initiatives will be discussed, along with their stimulating impact on the environment for technology transfer.

  4. Case Histories of Landslide Impact: A Database-driven Approach

    Science.gov (United States)

    Klose, Martin; Damm, Bodo

    2015-04-01

    Fundamental understanding of landslide risk requires in-depth knowledge of how landslides have impacted society in the past (e.g., Corominas et al., 2014). A key to obtain insights into the evolution of landslide risk at single facilities of critical infrastructures are case histories of landslide impact. The purpose of such historical analyses is to inform about the site-specific interactions between landslides and land-use activity. Case histories support correlating landslide events and associated damages with multiple control variables of landslide risk, including (i) previous construction works, (ii) hazard awareness, (iii) the type of structure or its material properties, and (iv) measures of post-disaster mitigation. It is a key advantage of case histories to provide an overview of the changes in the exposure and vulnerability of infrastructures over time. Their application helps to learn more about changing patterns in risk culture and the effectiveness of repair or prevention measures (e.g., Klose et al., 2014). Case histories of landslide impact are developed on the basis of information extracted from landslide databases. The use of path diagrams and illustrated flowcharts as data modeling techniques is aimed at structuring, condensing, and visualizing complex historical data sets on landslide activity and land-use. Much of the scientific potential of case histories simply depends on the quality of available database information. Landslide databases relying on a bottom-up approach characterized by targeted local data specification are optimally suited for historical impact analyses. Combined with systematic retrieval, extraction, and integration of data from multiple sources, landslide databases constitute a valuable tool for developing case histories that enable to open a whole new window on the study of landslide impacts (e.g., Damm and Klose, 2014). The present contribution introduces such a case history for a well-known landslide site at a heavily

    We analysed a period of the contemporary Brazilian history with the aim to discuss the inter-relationship between science, technology (S and T) and culture in a developing country, showing as a background for a case of study the history of the 'Instituto de Pesquisas Energeticas e Nucleares'. The history of Science and Technology, as a result of the human brain ability of innovate using the resources offered by nature, it is not only the description of successive findings carried out by talented men. It is a reflex of determined age of history as a consequence of accumulated knowledge connected also to human and cultural relationships, which together leads to the scientific and technological progress. In fact, the human brain and society march along together and can not be separated in this journey. In our study we recovered the initial steps of IPEN's outbreak; inserted its achievements in the context of the national policy for nuclear technology and evaluated how this policy was a reply of the governmental organizations to the worldwide situation. Finally, we spread the scientific ideas and technological findings of this institution, who has translate much of the life style and culture of our society. For this purposes, we analysed internal technical report series elaborated by several researchers and few testimonies. The Institution developed the fuel cycle technology, supplied radioisotopes for medical diagnosis and treatment purposes, generating economic resources for our country. The nuclear techniques are a relevant tool for researchers of this Institution applied for several purposes, including the assessment of the radioactivity levels in the environment, radioprotection, etc. Besides those applications, other techniques including the laser technology, the fuel cell, corrosion studies, etc, were implemented as a result of the improved capabilities and skills acquired during the almost 50 years of the Institute's existence.

  13. A case history: from traumatic repetition towards psychic representability.

    Science.gov (United States)

    Bichi, Estela L

    2008-06-01

    This paper is devoted principally to a case history concerning an analytic process extending over a period of almost ten years. The patient is B, who consulted the author after a traumatic episode. Although that was her reason for commencing treatment, a history of previous traumatogenic situations, including a rape during her adolescence, subsequently came to light. The author describes three stages of the treatment, reflected in three different settings in accordance with the work done by both patient and analyst in enabling B to own and work through her infantile and adult traumatic experiences. The process of transformation of traumatic traces lacking psychic representation, which was undertaken by both members of the analytic couple from the beginning of the treatment, was eventually approached in a particular way on the basis of their respective creative capacities, which facilitated the patient's psychic progress towards representability and the possibility of working through the experiences of the past. Much of the challenge of this case involved the analyst's capacity to maintain and at the same time consolidate her analytic posture within her internal setting, while doing her best to overcome any possible misfit (Balint, 1968) between her own technique and the specific complexities of the individual patient. The account illustrates the alternation of phases, at the beginning of the analysis, of remembering and interpretation on the one hand and of the representational void and construction on the other. In the case history proper and in her detailed summing up, the author refers to the place of the analyst during the analytic process, the involvement of her psychic functioning, and the importance of her capacity to work on and make use of her countertransference and self-analytic introspection, with a view to neutralizing any influence that aspects of her 'real person' might have had on the analytic field and on the complex processes taking place within

  15. PUBLIC COMPANIES IN LATIN AMERICA: HISTORY, CONCEPTS, CASES AND PERSPECTIVES

    Directory of Open Access Journals (Sweden)

    Guillermo Guajardo Soto

    2013-06-01

    Full Text Available The article highlights the need to address the history of public companies in Latin America for having played a significant role in regional development during the 20th Century, as well as for the current reappearance of these organisms in the international energy sector, for the strategic role they still play in many countries and, lastly, because decades of privatization have weakened the collective memory on these organisms, in favour of the prevailing neoliberal version which justified the sale of the public heritage. Do we have good knowledge on the history behind the importance and track record of public companies in Mexico and Latin America? How can their resistance after decades of privatizations be explained? These queries are replied in the current dossier of the Public Management Journal, which gathers a group of studies analysing the cases of Uruguay, Costa Rica, Bolivia, Brazil and Argentina between 1912 and 2012, shedding light on the entrepreneurial activities of the State under different economic models. In these countries, public companies have placed themselves in vital areas for the functioning of the economies, such as telecommunications, electricity,oil, transportation and, to a lesser extent, manufacturing. The final section is an invitation not only to read but also to initiate an agenda to analyse and allow revealing the complex history of these public organisms.

    This research examines the evolution of nuclear technology in Spain from the early years of the Franco dictatorship to the global financial crisis and technology's influence on Spanish culture. To this end, we take a sociological perspective, with science culture and social perceptions of risk in knowledge societies serving as the two elements of focus in this work. In this sense, this article analyses the transformation of social relationships in light of technological changes. We propose technology as a strategic place to observe the institutional and organisational dynamics of technologic-scientific risks, the expert role and Spain's science culture. In addition, more specifically, within the language of co-production, we 'follow the actor' and favour new forms of citizen participation that promote ethics to discuss technological issues.

    Full Text Available Cynicism and skepticism are nowadays conceived as curiosities in the history of philosophical thought, reduced to "eccentric" characters like Diogenes of Sinope and Pyrrho of Elis and a series of anecdotes about them.However, they have gone beyond classical antiquity to the present. Both schools of thought offer a constant challenge to the "official" thought bon ton: mocking and irreverent criticism in the case of the first and extreme relativism in the second.This paper presents an epistemological approach supporting the recovery of the cynicism and the pyrrhonian skepticism principles for the criticism of the historical thought in the modernity It is divided into two parts: the first one shows the broad features of these philosophical trends and the second examines their contributions to historical knowledge based on two cases: Cioran for the cynicism and Veyne for the skepticism.

    Four case histories of steam and gas turbine components degradation identified during operation and verified during overhaul are presented. The diagnosis was carried out before the overhauls to indicate major problems to the personnel of the plants. The estimation of degrees of degradation of the steam turbine components was carried out applying simplified flow equation considering three key pressures. In the case of the gas turbine the output capacity and pressures, temperature and air and gas flow were analyzed. The results obtained during on-line analysis were confirmed by measurements of the dimensions of degraded components during an overhaul. Also, the results obtained from a sophisticated computer program proved the usefulness of the applied methods.(author)

    Full Text Available The treatment of patients with complex regional pain syndrome (CRPS type 1 is challenging and unpredictable as the condition presents with vascular and neuropathic symptoms after nil or even minor injury to a peripheral nerve. The condition is one of a pain and motor dysfunction. The pathophysiology is not well understood and the relief of symptoms may change from being sympathetically mediated to sympathetically independent during  the course of the disease. At any stage physiotherapy has been advocated as the corner stone and most important aspect of treatment in the rehabilitation of these individuals but unfortunately it has been difficult to execute when pain is exacerbated due to allodynia (unbearable to touch or move and hyperalgesia. Best results have been obtained if the patients are recognised and treated in the early or acute phase and it has been found that through careful assessment and analysis these patients can be recognised by previous events that have occurred in their initial case history. The treatment in the acute stage with physiotherapy modalities such as electrical stimulation and acupuncture will produce an early cessation of the symptoms and prevention of the disease developing into the fully blown CRPS type 1 with irreversible and possibly atrophic consequences. Case histories have been presented that illustrate these important aspects and demonstrate  the value of early and the appropriate physiotherapy that may be more successful than other pharmacological and physical interventions in this disease.

    The research aims to investigate what key success factors (KSFs) of technological innovation in KAERI are, and to suggest how these findings are utilized for KAERI. In order to achieve these goals we have employed case study based on in-depth interview and literature review. And there are two fields of research in KAERI: one is nuclear energy-related research, the other is non energy-related research. The former is 'nuclear fuel cladding tube' which is an industrial product and being regarded as catch-up (or imitative) mode of technological innovation: the latter is 'HemoHIM', herbal composition of health functional food, which is consumer goods and regarded as creative (or innovative) mode of technological innovation. We found some KSFs in these two research and development cases in KAERI: firstly, to train researcher to be a 'product champion' who can fill in the gap of 'death valley' between pure research and commercialization: secondly, to build researchers' competency in order to catch up advanced countries' technological competencies. Thirdly, to amend institutional rules and regulations for commercializing processes of R and D outcomes, notably 'R and D joint venture by Government Research Institute (GRI) and private sector' fourthly, to enhance the capabilities of external management for researchers' technological innovation competency. And finally, we recommend using successful R and D cases as educational materials when training young researchers for sharing old generations' experiences and tacit knowledge.

  6. Case histories of West Valley spent fuel shipments: Final report

    Energy Technology Data Exchange (ETDEWEB)

    1987-01-01

    In 1983, NRC/FC initiated a study on institutional issues related to spent fuel shipments originating at the former spent fuel processing facility in West Valley, New York. FC staff viewed the shipment campaigns as a one-time opportunity to document the institutional issues that may arise with a substantial increase in spent fuel shipping activity. NRC subsequently contracted with the Aerospace Corporation for the West Valley Study. This report contains a detailed description of the events which took place prior to and during the spent fuel shipments. The report also contains a discussion of the shipment issues that arose, and presents general findings. Most of the institutional issues discussed in the report do not fall under NRC's transportation authority. The case histories provide a reference to agencies and other institutions that may be involved in future spent fuel shipping campaigns. 130 refs., 7 figs., 19 tabs.

  7. History of Antenna Technology for Mobile Communications in Korea

    Min, Kyeong-Sik; Park, Chul-Keun; Kang, Suk-Youb

    In this paper, we discuss the development of wireless and mobile communications in Korea, current technological trends, and the future outlook on technological developments. Since the introduction of the telegraph and the telephone in September 1885, Korea's wired and wireless communications industry has consistently developed for over 100 years. Since 1984, upon the provision of the mobile telecommunications service, the industry has seen drastic qualitative and quantitative growth in terms of both technical and economic aspects, which played a crucial role in the rapid growth of the digital industry in Korea. After the era of the analog cellular service based on the Advanced Mobile Phone System (AMPS), a precursor to the modern mobile service, Korea became the world's first country to commercialize Code Division Multiple Access (CDMA) in 1996 and succeeded in commercializing CDMA 2000 lx (IMT 2000) in 2001. With further developments in the mobile communication technology, the technology for antennas also saw drastic advancements. As the mobile antennas moved from the second to the third generation, they grew from external models to very small internal models. At the same time, they evolved into highly functional and high performance multiple band and wide band antennas. Furthermore, Korea was the first country to commercialize and offer the Wireless Broadband Internet (WiBro) service in 2006. By leading the wireless communications standardization and exerting remarkable efforts in research and development, Korea is consolidating its status as an Information Technology (IT) leader in the global market. The antenna's inherent importance will be further emphasized in the near future as it satisfies the performance and structural needs of portable terminals necessary for realizing the projected establishment of the ubiquitous world. It is thought that antenna technologies will not be limited to simple concepts as previously experienced but will utilize various kinds

    Objective To describe the specific features of the contact history of probable cases of severe acute respiratory syndrome (SARS) in Beijing. Methods Data of SARS cases notified from the Beijing Municipal Center for Disease Control and Prevention (BCDC) and supplemented by other channels were collected. All the data were analyzed by descriptive epidemiology. Results ①The number of probable cases with contact history was significantly higher than the excluded cases. ②The proportion of probable cases with contact history descended with epidemic development, but this situation did not occur in health care workers (HCWs). ③The fatality rate of probable cases with contact history was significantly higher than the cases without contact history (OR=1.489). ④The proportion of probable cases with contact history was 85.86% among health care workers, which was significantly higher than that of non-health care workers (85.86% v.s. 56.44%, OR=4.69). Conclusions ①The susceptible persons with contact history may not get infected, and the contact history is just a sufficient condition of infecting SARS; ②There are 3 conceivable reasons for the descending trend of the proportion in probable cases with contact history; ③The contact history is one of the risk factors of the death of SARS cases; ④The risk of contacting with SARS among health care workers is approximately 5 times higher than that of non-HCWs.

    This publication has been produced within the THERMIE B project `Interactive Promotion of Energy Technologies between Finland and Other EUCountries and to Estonia` (STR-0622-95-FI) as carried out for DG XVII of the European Commission. MOTIVA of Finntech Finnish Technology Ltd Oy has acted as the project co-ordinating body, with Ekono B.E., Ekono Energy Ltd and Friedemann and Johnson Consultants GmbH as partners. The main aim of the second phase of the project, as documented here, was to produce a publication in English on Finnish energy technologies, primarily in the building, industry and traffic sectors. The target distribution for this publication is primarily the EU countries through public and commercial information networks. During the work, the latest information on Finnish energy technologies has been collected, reviewed, screened and analysed in relation to the THERMIE programme. The following presentation consists of descriptions of case technologies; their background, technical aspects and energy saving potentials where applicable. The three RUE sectors; buildings, industry and traffic, are put forward in separate chapters. The building sector concentrates mostly in different control systems. New lighting and heating systems increase energy savings both in the large industrial sites and in private homes. In the industry sector new enhanced processes are introduced along with new products to increase energy efficiency. Traffic sector concentrates in traffic control and reducing exhaust gas emissions by new systems and programmes. The aim in Finland is to reduce exhaust gas emissions both by controlling the traffic efficiently and by developing fuels with lower emission levels. A lot is being done by educating the drivers and the public in efficient driving methods

    To provide an overview of the development of health technology assessment (HTA) in Germany since the 1990s. Analysis of key documents (e.g. literature, laws, and other official documentation) and personal experiences. Health technology assessment (HTA) entered the political agenda in Germany only in the mid-1990s, basically as the result of a top-down approach toward more efficiency in health care, but with a strong impetus of an evidence-based medicine movement. Accordingly, HTA became part of several healthcare reform laws since 1997, which led to the establishment of the Federal Joint Committee (G-BA) and the Institute for Quality and Efficiency in Health Care (IQWiG) in 2004. This tandem construction aims at using evidence in decision-making processes for coverage and other decisions. These developments have led to a considerable impact of HTA in Germany. In addition, a broad spectrum of activities at universities and in other organizations, such as the German Institute for Medical Documentation and Information (DIMDI), can be observed that contribute to both teaching and research in HTA. German researchers in the field of HTA are actively involved in international projects, such as EUNetHTA, and contribute to scientific conferences and journals.

    There is a continuing need for new health technologies to address the disease burdens of developing countries. In the last decade Product Development Partnerships (PDP) have emerged that are making important contributions to the development of these technologies. PDPs are a form of public private partnerships that focus on health technology development. PDPs reflect the current phase in the history of health technology development: the Era of Partnerships, in which the public and private sectors have found productive ways to collaborate. Successful innovation depends on addressing six determinants of innovation. We examine four case studies of PDPs and show how they have addressed the six determinants to achieve success.

    Full Text Available Teacher and student attitudes towards the technology enhanced instruction plays a critical role in determining its effectiveness. The purpose of the study is to examine Turkish and American students’ attitudes and thoughts toward the use of educational technologies in history courses, and to compare the results to determine whether there are any differences between the attitudes of Turkish and American student. This study was conducted with 197 American students from Upper Saint Claire High school in Pittsburgh, PA, and 214 Turkish students from Konya High school who volutered for this study. The required data for this study were gathered by a 26-item technology questionnaire, which included 7 multiple-choice questions and 19 Likert scale questions. This questionnaire was developed to gather data on five different areas of interest: (1 demographic information, (2 participants’ computer- and Internet-usage skills, (3 the level of technology used in history classrooms, (4 participants’ attitudes toward technology-enhanced history education, and (5 participants’ attitudes toward history. Most of the Turkish and American students rated themselves as being very well experienced on the eight computer- and Internet-usage skills targeted in this study. But the comparison of the data indicated that American students have higher computer- and Internet-usage skills than Turkish students do, and this difference is statistically significant (p = 0.001. Most of the Turkish and American students showed positive attitudes on using educational technologies in history classrooms. A majority of the Turkish and American students stated that they would be able to focus and learn better if more technological materials were used in classroom activities, and this, in turn, would increase their academic achievements.

  19. Working knowledges before and after circa 1800: practices and disciplines in the history of science, technology, and medicine.

    Science.gov (United States)

    Pickstone, John V

    2007-09-01

    Historians of science, inasmuch as they are concerned with knowledges and practices rather than institutions, have tended of late to focus on case studies of common processes such as experiment and publication. In so doing, they tend to treat science as a single category, with various local instantiations. Or, alternatively, they relate cases to their specific local contexts. In neither approach do the cases or their contexts build easily into broader histories, reconstructing changing knowledge practices across time and space. This essay argues that by systematically deconstructing the practices of science and technology and medicine (STM) into common, recurrent elements, we can gain usefully "configurational" views, not just of particular cases and contexts but of synchronic variety and diachronic changes, both short term and long. To this end, we can begin with the customary actors' disciplines of early modern knowledge (natural philosophy, natural history, mixed mathematics, and experimental philosophy), which can be understood as elemental "ways of knowing and working," variously combined and disputed. I argue that these same working knowledges, together with a later mode-synthetic experimentation and systematic invention-may also serve for the analysis of STM from the late eighteenth century to the present. The old divisions continued explicitly and importantly after circa 1800, but they were also "built into" an array of new sciences. This historiographic analysis can help clarify a number of common problems: about the multiplicity of the sciences, the importance of various styles in science, and the relations between science and technology and medicine. It suggests new readings of major changes in STM, including the first and second scientific revolutions and the transformations of biomedicine from the later twentieth century. It offers ways of recasting both microhistories and macrohistories, so reducing the apparent distance between them. And it may thus

  1. The case for researching the history of community nursing practice.

    Science.gov (United States)

    Whitehead, D

    2001-05-01

    Despite a flurry of interest in the 1980s, the adoption of a positivist, objective, scientific paradigm for nursing research has led to a rejection of the study of nursing history as a valid pursuit in recent years. In this article, it is argued that this is a precarious situation. By not examining the history of the profession, nursing -- and in particular community nursing -- undermines its efforts to validate itself within the wider health-care arena. Nursing must learn from the mistakes of the past, as well as the successes, but do so in a critical way that does not romanticize its history.

  5. Transforming the Narrative of the History of Chinese Technology: East and West in Bertrand Gille’s Histoire des Techniques

    Directory of Open Access Journals (Sweden)

    Yao Dazhi

    2015-05-01

    Full Text Available In his magisterial The History of Techniques, the French historian of technology Bertrand Gille (1920–1980 constructs a Western-centric world history of technology based on a technical systems approach. In doing so, he is forced to deal with the tension between Western-centric approaches and the conventional narrative of the history of Chinese technology. In order to avoid internal contradictions within his world history framework, Gille reconfigures the historical narrative about ancient China’s great inventions, arguing against unidirectional technology transfer and introducing the alternative notions of technological concomitant evolution and technological exchange. While Gille integrates ancient China into the general technological development of the world, he treats China as a blocked technical system and as “the other” in the West’s technological self-perception.

    Full Text Available The following paper is concerned with elucidating an account of forms of new localism as they relate to the concept of ‘habitele’, a conceptual framework that helps us understand new forms of relatedness in the digitally mediated world. In doing this it will also reflect back on the concept and draw out as yet unconsidered elements based upon issues of fluidity, mobility, and what we will call ‘distal-locals’. The paper is centred around two case studies: the first is of a smart phone app, vouchercloud and details the way that the offering of money-off vouchers rests on particular notions of the local; while the second is of a environment organization who uses information technology to promote their activities. It is premised upon a history of work in the sociology of science and technology studies (STS and in particular a set of conceptual and methodologicalresources that helps to reveal the complexities of notions such as “the local”.

  11. Natural history and information overload: The case of Linnaeus.

    Science.gov (United States)

    Müller-Wille, Staffan; Charmantier, Isabelle

    2012-03-01

    Natural History can be seen as a discipline paradigmatically engaged in 'data-driven research.' Historians of early modern science have begun to emphasize its crucial role in the Scientific Revolution, and some observers of present day genomics see it as engaged in a return to natural history practices. A key concept that was developed to understand the dynamics of early modern natural history is that of 'information overload.' Taxonomic systems, rules of nomenclature, and technical terminologies were developed in botany and zoology to catch up with the ever increasing amount of information on hitherto unknown plant and animal species. In our contribution, we want to expand on this concept. After all, the same people who complain about information overload are usually the ones who contribute to it most significantly. In order to understand this complex relationship, we will turn to the annotation practices of the Swedish naturalist Carl Linnaeus (1707-1778). The very tools that Linnaeus developed to contain and reduce information overload, as we aim to demonstrate, facilitated a veritable information explosion that led to the emergence of a new research object in botany: the so-called 'natural' system.

    2002-01-01

    The paper investigates how visual resources can be fruitfully used to study the history of science, medicine, and technology from a practical point of view. Two new international and interdisciplinary trends within recent historiography are reviewed: the history of visualisation and the history of popularisation. The results of both trends need to be combined in order to understand the ways in which images of science have been used to communicate science from its place of production within the laboratory to its users within the wider society. From the proposed perspective, visual representations of science (i.e. portraits, images of scientific instruments, measurement results and abstractions) are discussed as a distinct medium in which knowledge producers have transmitted and transformed their findings to the acquirers of knowledge. The paper introduces the wider historiographical framework for a discussion of the following four papers published in this issue of NTM.

    Drill-bit seismic technology provides useful real-time information that reduces uncertainty for the driller. This second part of a two-part series provides real examples, describes the current state of technology and experience, and discusses techniques that will add value through the incorporation of additional information sources. To date, this technology has been used on more than 50 wells in all areas of the world, including a deepwater job in 1,200 m of water. As of March 1998, there were five ongoing jobs in Oman, Indonesia, Malaysia, Gulf of Mexico, and South America. The following examples of oil and gas wells demonstrate the application of the drill-bit seismic technique and show benefits that can be brought to the drilling process.

    2007-06-01

    Full Text Available Apart from work in the mining industry during the 1950s, the first real Operations Research (OR group in South Africa was established at CSIR in the early 1960s. Those initially involved in this group played a significant role in establishing OR at various universities in South Africa. The OR group at CSIR did, however, continue and today the group still exists. This paper presents a brief history of this group and endeavours to provide a glimpse of some of the projects conducted over the many years since its establishment.

    2009-01-01

    The widespread use of endosseous osseointegrated implants to replace missing natural teeth increases the chances of implant complications and failures, despite the high initial success rate reported in the literature. Implant fracture is one possible complication that results in ultimate failure of the dental implant. Such a complication poses a management crisis even for the most experienced clinician. This article reports on a case of implant fracture, its possible causes, and how the case was managed.

    The incidence of melanoma in Denmark has immensely increased over the last 10 years making Denmark a high risk country for melanoma. In the last two decades multiple public campaigns have sought to increase the awareness of melanoma. Family history of melanoma is a known major risk factor...... but previous studies have shown that self-reported family history of melanoma is highly inaccurate. These studies are 15 years old and we wanted to examine if a higher awareness of melanoma has increased the accuracy of self-reported family history of melanoma. We examined the family history of 181 melanoma...... probands who reported 199 cases of melanoma in relatives, of which 135 cases where in first degree relatives. We confirmed the diagnosis of melanoma in 77% of all relatives, and in 83% of first degree relatives. In 181 probands we validated the negative family history of melanoma in 748 first degree...

  6. Case teaching in economics: History, practice and evidence

    Directory of Open Access Journals (Sweden)

    Guglielmo Volpe

    2015-12-01

    Full Text Available Case studies are, normally, real-world problems that might include relevant or irrelevant data, correct or incorrect analysis and that require some sort of interpretation or solution. The use of case studies has been a common feature of undergraduate studies in business and law for a long time. In recent years, the so-called “case method” has become quite popular in economics education as well since it is believed to help the development to three key objectives in economics education: the mastering of economics principles, the application of principles to reality and the systematic analysis of policy issues. Coupled with student-centred approaches to learning, the case method can prove a very effective method in helping students to achieve a deeper understanding of both economic theory and policy analysis. The article provides an account of how case studies can be effectively used in economics teaching and reviews the empirical evidence on the effectiveness of the approach.

  7. Sudden unexplained death in childhood: A comparison of cases with and without a febrile seizure history.

    Science.gov (United States)

    Hesdorffer, Dale C; Crandall, Laura A; Friedman, Daniel; Devinsky, Orrin

    2015-08-01

    We considered whether a subset of children with sudden unexplained death in childhood (SUDC) and a history of febrile seizures (FS) may parallel those in sudden unexpected death in epilepsy (SUDEP). The prevalence of a history of FS was examined, and factors that may distinguish SUDC cases with and without FS were described. Characteristics were assessed in 123 consecutive children with SUDC reported to the SUDC program (4/1/11-3/31/14) by their parents. Parental interview covered the decedent's medical history, circumstances of death, environmental factors, cause of death, and family medical history. Features of SUDC cases were compared by FS history. Overall, 31.7% of SUDC cases had a history of FS, among which 74.4% had simple FS. Compared to those without a history of FS, a history of FS was associated with a greater median age at death (p = 0.03) and death during the weekdays (p = 0.02). Terminal fever was similar in those with and without FS. The median time from FS to death was 6.0 months (interquartile range [IQR] 3.0-10.0). In all SUDC cases, prone position at death, death during sleep, and unwitnessed deaths predominated. There are parallels among SUDC, sudden infant deaths, and sudden unexpected death in epilepsy (SUDEP) with regard to prone position, unwitnessed deaths mostly during sleep, and male predominance. In children with SUDC and a history of FS, terminal fever may increase the risk for an unwitnessed terminal seizure. The greater than expected prevalence of a FS history and the proportion with terminal fever or illness in this cohort suggests that some SUDC deaths may be seizure related and therefore have potential commonalities with SUDEP.

    Secondary petroleum inclusions in reservoir sandstones in the Froy Field and the Rind Discovery are used in combination with burial history modelling, reservoir oils and core extracts to shed light on how and when these structures received their hydrocarbons charges. Analysis of normal alkane and biomarker distributions in these three data sets: fluid inclusions, core extracts and drill stem tests (DSTs) provide information on the changes in organic facies and maturity of petroleum in the various reservoir strata over time. The geochemistry of core extracts and DST oils in Rind and Froy reveal that the maturity of the Rind petroleum system is higher and also of slightly less anoxic facies compared to the oil present in the Froy system. Biodegraded oil is found today in a small sub-compartment of the Froy Field. Using the burial history of the Froy and the assumption that biodegradation effectively comes to a halt at 70-80DegC, we tentatively conclude that the filling of this sub-compartment and the biodegradation off the oil must have occurred earlier than 30-40 m.y.b.p. and before oil from the Upper Jurassic Draupne shales more recently homogeneously filled the main Froy structure. At 30-40 m.y.b.p., the Froy structure was at a depth of 1.5-2 km, compared to the present depth of 3.5-4 km, and it is more than likely that neither the Heather nor the Draupne Formations were mature in the paleo-drainage area of the field at this time. Still, the stratigraphically deeper Dunlin Formation could have been mature and the geochemical signatures of the now biodegraded oil correlates with known signatures from the Dunlin Formation in this region. In the Rind Discovery, no fluorescent petroleum inclusions are observed in K-feldspar overgrowths. However, the number of inclusions in quartz and plagioclase is larger than that observed in the shallower Froy Field. From the mean homogenisation temperatures of the petroleum inclusions, which are close to the present reservoir

  12. Using History To Teach Scientific Method: The Case of Argon

    Science.gov (United States)

    Giunta, Carmen J.

    1998-10-01

    The history of science is full of stories that exhibit scientific methodology to an exemplary degree. Such stories can be vehicles for the teaching of scientific thought to non-science majors in general-education science courses, particularly if they do not involve much technical background and are told in ordinary language. This paper illustrates the kind of lessons that can be gleaned from such stories by examining the discovery of argon, an episode replete with examples of how scientists pursue knowledge. Lord Rayleigh's use of multiple methods to determine the density of nitrogen; his persistent tracking down of a small but real anomaly in those measurements; his and William Ramsay's eventual realization that the anomaly was due to a previously unknown but relatively plentiful component of the atmosphere, an inert, monatomic gas; and Ramsay's subsequent successful search for other members of the inert gas family all illustrate the scientific approach to knowledge. This story can be presented to students in Rayleigh's words, annotated to supply background material and to pose questions.

    2012-05-01

    In the process of excavating seven parallel tunnels at the Jinping II Hydropower Station, several extremely intense rockbursts occurred, killing and injuring construction workers and damaging several sets of equipment. Based on the characteristics and mechanisms of these rockbursts, four typical events were selected and their temporal and spatial characteristics were here described in detail. The geological conditions revealed after the rockbursts were surveyed carefully. The responses of support elements were also analyzed. The details documented in each case provide not only an important reference for understanding the development mechanisms of rockbursts but also a basis for the selection and development of rockburst prevention measures in deep hard rock tunnels.

  15. Isolated cases? The history and historiography of Australian medical research.

    Science.gov (United States)

    Hobbins, Peter; Hillier, Kathryn

    2010-01-01

    For over two hundred years, Australia has been portrayed as a terminus rather than a hub for scientific exchange. Alongside narratives valorising the struggle for a distinct national identity, the motif of isolation abounds in the historiography of Australian medical research. Yet these orthodoxies are ripe for rescripting, as illustrated by a symposium held in Sydney in 2010: Isolated Cases? 100 Years of Australian Medical Research. Weaving together several historical themes from this conference with wider historiographic threads, this article questions many prevailing representations. In particular the authors argue that rather than isolation or dependency, Australian medical science has been characterised by a profound interdependence across two centuries of antipodean endeavour.

    Partial trisomy 19p was noted in an infant delivered at 39 weeks gestation with intrauterine growth retardation (IUGR), bilateral club feet, renal abnormalities, hearing deficit, and multiple dysmorphic features. Chromosomes obtained following amniocentesis at 32 weeks gestation revealed that the fetus was partially trisomic for 19p and partially monosomic for a portion of the terminal band of 3q, having inherited a derivative chromosome 3 from her father [46,XX,-3,+der(3)t(3;19)(q29;p13.2)pat]. The father was found to be the carrier of a balanced translocation between chromosomes 3 and 19 [46,XY,t(3;19)(q29;p13.2)]. The only other case of partial trisomy 19p previously reported was an infant with partial trisomy 19p and partial monosomy 13q who died at 59 days of age. This report by Byrne et al. [(Am J Hum Genet 1980: 32:64A] is similar to our case with respect to IUGR, small palpebral fissures, and ear anomalies.

  18. Tool or Science? The History of Computing at the Norwegian University of Science and Technology

    Nordal, Ola

    One may characterize the history of computing at the Norwegian University of Science and Technology by a tension between the computer as a tool in other disciplines and computer science as discipline in itself. This tension has been latent since the pioneering period of the 1950s until today. This paper shows how this have been expressed in the early attempts to take up computing at the University, and how it gave the Division of Computer Science a fairly rough start when it opened in 1972.

    McVey, Scott; Shi, Jishu

    2010-05-01

    The use of vaccines in veterinary medicine has progressed from an experimental adventure to a routine and relatively safe practice. The common and aggressive use of efficacious vaccines has been responsible for the control and eradication of several diseases. Despite progress in research technologies, diagnostic capabilities, and manufacturing methods, there remain many infectious diseases for which no effective vaccines exist. Global availability, field compliance, effectiveness, and safety are also significant concerns. This review addresses the history, current practices, and potential future improvements of vaccine use in veterinary medicine.

    2010-01-01

    Autoimmune lymphoproliferative syndrome (ALPS) is a rare disease caused by defective lymphocyte apoptosis and is characterized by non-malignant lymphoproliferation, hepatosplenomegaly, autoimmune manifestations and increased risk of both Hodgkin's and non-Hodgkin's lymphoma. Most forms of the disease are due to germ line mutations of the FAS gene and manifest during the first years of life with fluctuating lymphadenopathies, hemolysis, immune thrombocytopenia. During the second decade of life disease manifestations improve spontaneously but autoimmune problems still occur and there is an increased risk of lymphoproliferative malignancy. We describe a typical case of ALPS in a now 44 year old man, followed since the age of 2 for disease manifestations that were unclear at the beginning.

    Full Text Available Gränsöverskridande Nordisk Undervisning/Utdanelse (GNU, meaning Cross-Border Nordic Education, the larger Nordic project, under which this case study was carried out, aims at developing innovative, cross-border teaching models in different subject domains in elementary school, including mathematics, language, science, social studies and history. This paper provides an in-depth description and analysis of how four social science and history elementary school teachers and their 70 students (5th–7th grades worked together between November 2011 and December 2012. Previous research regarding the use of information and communication technology (ICT in history education in elementary schools is limited, thus calling for contemporary investigations in this particular subject domain. The Technological Pedagogical Content Knowledge (TPACK model, enhancing the combination of teachers’ pedagogical, content and technical competence, was used as the analytical framework, together with nation-specific curricula and the European Union’s recommendations regarding students’ skills for lifelong learning. A range of empirical materials was analyzed, such as classroom observations, students’ video productions, texts and photos distributed and shared on a mutual blog, real-time interaction and teachers’ communication. The teachers tried out two ICT didactic models. In the asynchronous model, the major focus was on the form and content of the video productions being shared, whereas work with the synchronous model concentrated on the content and quality of the communication. Notwithstanding obstacles, cross-border collaboration provided added value. The nation-specific differences triggered curiosity and motivation to produce digital presentations of history content to be understood by the students in the three nations, facilitating goal fulfillment in communication skills and digital competence. However, achieving subject-specific goals in history

    1996-01-01

    The Burn Unit of Dona Estefânia Hospital admitted a total of 454 patients from January 1992 to January 1995, 24 of these patients suffered from electric shock. Of these 24 patients 3 suffered burns in the mouth, 15 in one or both hands and 6 multiple burns. In 19 patients the burns were up to 1%. A description is made of 5 cases, male children between the ages of 9 and 13 years, which were deemed severe. The incidents occurred outdoors with different voltages and in activities considered of ludic or experimental nature: two on the roof of a house, two with railway cables and one with an electrical cable in a port zone. The burnt areas vary between 4% and 70%, all of them 2nd and 3rd degree, with hospitalization lasting from 36 to 116 days. In addition to early and coordinated medical and rehabilitative treatment, according to individual needs, a description is also made of the cutaneous sequelae (deforming cicatrices, bridles), neurologic and psychologic sequelae, with emphasis on a patient who underwent amputation of the lower left leg and 4th and 5th ranges of the right foot. It was concluded that measures should be taken in education and legislation to prevent these accidents. Relevance is given to the need for a multidisciplinary team and specialized center for the treatment of these patients.

A comparative ref lection on the Dictionary of Technology and Pedagogy of the Oppressed, Paulo Freire most renowned book, is possible due to the clear effort of both works directed against the dehumanization and conversion of the pedagogical process into technology. Freire educational process sees as a simulacrum of the banking system while the Dictionary of Technology very closely, but more generally sees it as the predominance of illusion, no matter who is oppressed by whom. The illusion would exist even in a world without a relationship of dominance, because the dismissal of oppression will not liberate us from the history.

    2016-03-01

    In thirty years of teaching a capstone ``Science, Technology, and Society'' course to undergraduate students of all majors, I have found that, upon entering STS, to most of them the Manhattan Project seems about as remote as the Civil War; few can describe the difference between nuclear and large non-nuclear weapons. With similar lack of awareness, many students seem to think the Big Bang was dreamed up by science sorcerers. One might suppose that a basic mental picture of weapons that held entire populations hostage should be part of informed citizenship. One might also suppose that questions about origins, as they are put to nature through evidence-based reasoning, should be integral to a culture's identity. Over the years I have found the history of physics to be an effective tool for bringing such subjects to life for STS students. Upon hearing some of the history behind (for example) nuclear weapons and big bang cosmology, these students can better imagine themselves called upon to help in a Manhattan Project, or see themselves sleuthing about in a forensic science like cosmology. In this talk I share sample student responses to our class discussions on nuclear weapons, and on cosmology. The history of physics is too engaging to be appreciated only by physicists.

    2016-06-01

    Genes, behaviour, and the environment are known to be the major risk factors for common diseases. When the patient visits a physician, typical questions include family history (genes) and lifestyle of the patient (behaviour), but questions concerning environmental risk factors often remain unasked. It is ironic that 25 centuries ago Hippocrates, known as the father of medicine, noted the importance of environmental exposure in medical investigation as documented in his classic work, "Airs, Waters, Places", yet the practice of routinely incorporating environmental risk factors is still not in place. Modern epigenetic studies have found that unhealthy lifestyle and environmental factors can cause changes to our genes that can increase disease risk factors. Therefore, attempting to solve the puzzle of diseases using heredity and lifestyle alone will be incomplete without accounting for the environmental exposures. The primary reason why environmental exposure has not yet been a routine part of the patient's medical history is mostly due to our inability to provide clinicians useful measures of environmental exposures suitable for their clinical practices. This presentation will discuss advances in geospatial technology that show the potential to catalyse a paradigm shift in medical practice and health research by allowing environmental risk factors to be documented as the patient's "Geographic Medical History". In order to accomplish this we need information on: a) relevant spatiotemporal environmental variables, and b) location of the individual in that person's dynamic environment. Common environmental agents that are known to interact with genetic make-up include air pollutants, mold spores, pesticides, etc. Until recently, the other component, location of an individual was limited to a static representation such as residential or workplace location. Now, with the development of mobile technology, changes in an individual's location can be tracked in real time if

The study conducted through single case study on SWRO installation in Mandangin Island, East Java, Indonesia. Results of case study indentify the existence of government incentive in the form of direct subsidies to decrease the price of clean water. Although successful in reducing the price of water, but effectiveness of the subsidy on the sustainability of SWRO is still low, which is operates only 30% in a year. Further analysis shows that these subsidies actually be counter-productive to the sustainability of SWRO installation.

  8. Hurdling barriers through market uncertainty: Case studies ininnovative technology adoption

    The crisis atmosphere surrounding electricity availability in California during the summer of 2001 produced two distinct phenomena in commercial energy consumption decision-making: desires to guarantee energy availability while blackouts were still widely anticipated, and desires to avoid or mitigate significant price increases when higher commercial electricity tariffs took effect. The climate of increased consideration of these factors seems to have led, in some cases, to greater willingness on the part of business decision-makers to consider highly innovative technologies. This paper examines three case studies of innovative technology adoption: retrofit of time-and-temperature signs on an office building; installation of fuel cells to supply power, heating, and cooling to the same building; and installation of a gas-fired heat pump at a microbrewery. We examine the decision process that led to adoption of these technologies. In each case, specific constraints had made more conventional energy-efficient technologies inapplicable. We examine how these barriers to technology adoption developed over time, how the California energy decision-making climate combined with the characteristics of these innovative technologies to overcome the barriers, and what the implications of hurdling these barriers are for future energy decisions within the firms.

  9. New surveillance technologies and their publics: A case of biometrics.

    Martin, Aaron K; Donovan, Kevin P

    2015-10-01

    Before a newly-elected government abandoned the project in 2010, for at least eight years the British state actively sought to introduce a mandatory national identification scheme for which the science and technology of biometrics was central. Throughout the effort, government representatives attempted to portray biometrics as a technology that was easily understandable and readily accepted by the public. However, neither task was straightforward. Instead, particular publics emerged that showed biometric technology was rarely well understood and often disagreeable. In contrast to some traditional conceptualizations of the relationship between public understanding and science, it was often those entities that best understood the technology that found it least acceptable, rather than those populations that lacked knowledge. This paper analyzes the discourses that pervaded the case in order to untangle how various publics are formed and exhibit differing, conflicting understandings of a novel technology.

  10. Taxonomy and why history of science matters for science: a case study.

    Science.gov (United States)

    Hamilton, Andrew; Wheeler, Quentin D

    2008-06-01

    The history of science often has difficulty connecting with science at the lab-bench level, raising questions about the value of history of science for science. This essay offers a case study from taxonomy in which lessons learned about particular failings of numerical taxonomy (phenetics) in the second half of the twentieth century bear on the new movement toward DNA barcoding. In particular, it argues that an unwillingness to deal with messy theoretical questions in both cases leads to important problems in the theory and practice of identifying taxa. This argument makes use of scientific and historical considerations in a way that the authors hope leads to convincing conclusions about the history of taxonomy as well as about its present practice.

  17. Networks dynamics in the case of emerging technologies

    2016-07-01

    This research in progress aims at increasing our understanding of how collaborative networks form, evolve and are configured in the case of emerging technologies. The architecture of the relationships among the variety of organisational actors involved in the emergence process exerts a significant influence in shaping technological change in certain directions rather than others, especially in the early stage of emergence. As a result, socially optimal or desirable technological trajectories may be ‘opportunistically’ rejected. Our empirical analysis is based on a case-study of an emerging medical technology, namely ‘microneedles’. On the basis of co-authorship data reported in 1,943 publications on the topic from 1990 to 2014, longitudinal collaboration (co-authorship) networks were built at two levels: affiliation and author. We examined the dynamics of co-authorship networks by building on recent methodological advancements in network analysis, i.e. Exponential Random Graph Models (ERGMs). These models enable us to make statistical inferences about on the extent to which a network configuration occurs more than could be expected by chance and to identify which social mechanisms may be shaping the network in certain configurations. The findings of the statistical analyses (currently in progress) combined with the qualitative understanding of the case will increase our understanding of which mechanisms are more likely to drive the network dynamics in the case of emerging technologies. These include evidence of the extent to which the likelihood of forming, maintaining, or terminating ties among actors (authors or affiliations) is affected by actors’ covariates such as types of organisations, diversity/specialisation of the research undertaken, and status. These findings have potential to provide important inputs for policymaking process in the case of emerging technologies. (Author)

  18. Rocketing into the future the history and technology of rocket planes

    CERN Document Server

    van Pelt, Michel

    2012-01-01

    Rocketing into the Future journeys into the exciting world of rocket planes, examining the exotic concepts and actual flying vehicles that have been devised over the last one hundred years. Lavishly illustrated with over 150 photographs, it recounts the history of rocket planes from the early pioneers who attached simple rockets on to their wooden glider airplanes to the modern world of high-tech research vehicles. The book then looks at the possibilities for the future. The technological and economic challenges of the Space Shuttle proved insurmountable, and thus the program was unable to fulfill its promise of low-cost access to space. However, the burgeoning market of suborbital space tourism may yet give the necessary boost to the development of a truly reusable spaceplane.

  12. Graeco-Roman case histories and their influence on Medieval Islamic clinical accounts.

    Science.gov (United States)

    Alvarez Millan, C

    1999-04-01

    The medieval Islamic medical tradition was the direct heir of Classical and Hellenistic medicine thanks to an unprecedented movement of translation into Arabic, commentaries and systematizations of Greek scientific texts. In the process of assimilation, not only theoretical principles, but also literary models of presenting medical knowledge were adopted, amongst them the case history. Since the clinical account can be used as a tool for medical instruction as well as an instrument for professional self-promotion, this study seeks to investigate which purpose most motivated Islamic physicians, and to demonstrate the extent to which they were influenced by the stylistic patterns which served them as a model. This article comprises an analysis of the context, literary devices and purpose of case histories of the Epidemics, Rufus of Ephesos and Galen, and compares them with those by the tenth-century Islamic physician Abu Bakr Muhammad b. Zakariya al-Razi. Author of the largest number of case histories preserved within the medieval Islamic medical literature, al-Razi's clinical records constitute an instrument with which to study and expand medical knowledge as well as providing useful material for students' medical training. Although al-Razi fused elements from the sources which served him as a model, he did not emulate Galen's use of the clinical history to assert himself in order to gain authority and prestige, but remained faithful to the Hippocratic essence.

  13. Accidental carbon monoxide poisoning presenting without a history of exposure: A case report

    Directory of Open Access Journals (Sweden)

    Bennetto Luke

    2008-04-01

    Full Text Available Abstract Introduction Carbon monoxide poisoning is easy to diagnose when there is a history of exposure. When the exposure history is absent, or delayed, the diagnosis is more difficult and relies on recognising the importance of multi-system disease. We present a case of accidental carbon monoxide poisoning. Case presentation A middle-aged man, who lived alone in his mobile home was found by friends in a confused, incontinent state. Initial signs included respiratory failure, cardiac ischaemia, hypotension, encephalopathy and a rash, whilst subsequent features included rhabdomyolysis, renal failure, amnesia, dysarthria, parkinsonism, peripheral neuropathy, supranuclear gaze palsy and cerebral haemorrhage. Despite numerous investigations including magnetic resonance cerebral imaging, lumbar puncture, skin biopsy, muscle biopsy and electroencephalogram a diagnosis remained elusive. Several weeks after admission, diagnostic breakthrough was achieved when the gradual resolution of the patient's amnesia, encephalopathy and dysarthria allowed an accurate history to be taken for the first time. The patient's last recollection was turning on his gas heating for the first time since the spring. A gas heating engineer found the patient's gas boiler to be in a dangerous state of disrepair and it was immediately decommissioned. Conclusion This case highlights several important issues: the bewildering myriad of clinical features of carbon monoxide poisoning, the importance of making the diagnosis even at a late stage and preventing the patient's return to a potentially fatal toxic environment, and the paramount importance of the history in the diagnostic method.

    In this report of two new cases of liver angiosarcoma (ASL) among plastic industry workers, the authors present the history and perspectives of this problem. The first cases of ASL have been registered since 1974, and in 1984, the European register of angiosarcoma was founded. In this register, 11 cases of ASL and one case of haemangiopericytoma have been registered from Croatia, all from a single plastics plant near Split. Two new cases of ASL (in retired autoclave cleaners, who were exposed to a concentration of 500-1000 ppm vinyl chloride monomer (VCM) during the working process) in the same plant are represented. They were detected with combined techniques of ASL detection, and both are still alive. The diagnoses have been histologically confirmed: one of them was surgically treated with segmental liver resection. The appearance of new cases of ASL confirms the perspective presented in the last report by the same authors.

    2009-01-01

    Point-of-care technologies have been heralded as enablers of quality care and efficiency. Fueling this reputation is the assumption that these technologies are seamlessly integrated with electronic medical records. In turn, this assumption leads to caregivers' heightened expectations of the capabilities of point-of-care technologies and, when not met, to their frustration with information systems personnel. The case study presented in this article documents an actual hospital's journey to integration. In doing so, it enumerates the technical challenges faced by the organization in layperson's terms and attempts to educate clinical personnel in the intricacies of integrating new health care technologies with existing systems. The drivers to integration were a primary focus on error reduction and an active collaboration among stakeholders. Individuals became learners outside the boundaries of their professional expertise. This cross-functional approach eventually led to simultaneous quality and efficiency gains.

  18. Preservation of Earth Science Data History with Digital Content Repository Technology

    Wei, Y.; Pan, J.; Shrestha, B.; Cook, R. B.

    2011-12-01

    An increasing need for derived and on-demand data product in Earth Science research makes the digital content more difficult for providers to manage and preserve and for users to locate, understand, and consume. Specifically, this increasing need presents additional challenges in managing data processing history information and delivering such information to end users. For example, the North American Carbon Program (NACP) Multi-scale Synthesis and Terrestrial Model Intercomparison Project (MsTMIP) chose a modified SYNMAP land cover data as one of the input driver data for participating terrestrial biospheric models. The global 1km resolution SYNMAP data was created by harmonizing 3 remote sensing-based land cover products: GLCC, GLC2000, and the MODIS land cover product. The original SYNMAP land cover data was aggregated into half and quarter degree resolution. It was then enhanced with more detailed grassland and cropland types. Currently, there lacks an effective mechanism to convey this data processing information to different modeling teams for them to determine if a data product meets their needs. It still highly relies on offline human interaction. The NASA-sponsored ORNL DAAC has leveraged the contemporary digital object repository technology to promote the representation, management, and delivery of data processing history and provenance information. Within digital object repository, different data products are managed as objects, with metadata as attributes and content delivery and management services as dissemination methods. Derivation relationships among data products can be semantically referenced between digital objects. Within the repository, data users can easily track a derived data product back to its origin, explorer metadata and documents about each intermediate data product, and discover processing details involved in each derivation step. Coupled with Drupal Web Content Management System, the digital repository interface was enhanced to

  20. GEOGRAPHIC MEDICAL HISTORY: ADVANCES IN GEOSPATIAL TECHNOLOGY PRESENT NEW POTENTIALS IN MEDICAL PRACTICE

    Directory of Open Access Journals (Sweden)

    F. S. Faruque

    2016-06-01

    Full Text Available Genes, behaviour, and the environment are known to be the major risk factors for common diseases. When the patient visits a physician, typical questions include family history (genes and lifestyle of the patient (behaviour, but questions concerning environmental risk factors often remain unasked. It is ironic that 25 centuries ago Hippocrates, known as the father of medicine, noted the importance of environmental exposure in medical investigation as documented in his classic work, “Airs, Waters, Places”, yet the practice of routinely incorporating environmental risk factors is still not in place. Modern epigenetic studies have found that unhealthy lifestyle and environmental factors can cause changes to our genes that can increase disease risk factors. Therefore, attempting to solve the puzzle of diseases using heredity and lifestyle alone will be incomplete without accounting for the environmental exposures. The primary reason why environmental exposure has not yet been a routine part of the patient’s medical history is mostly due to our inability to provide clinicians useful measures of environmental exposures suitable for their clinical practices. This presentation will discuss advances in geospatial technology that show the potential to catalyse a paradigm shift in medical practice and health research by allowing environmental risk factors to be documented as the patient’s “Geographic Medical History”. In order to accomplish this we need information on: a relevant spatiotemporal environmental variables, and b location of the individual in that person’s dynamic environment. Common environmental agents that are known to interact with genetic make-up include air pollutants, mold spores, pesticides, etc. Until recently, the other component, location of an individual was limited to a static representation such as residential or workplace location. Now, with the development of mobile technology, changes in an individual’s location

    2015-09-01

    Full Text Available For this article, the authors retrieved two curious cases of nonconformist TV from the archives of The Netherlands Institute of Sound and Vision. Being made in the late 1970s and early 1980s, the two cases represent an alternative history of broadcast television in the Netherlands. Whereas Neon (1979-1980 aimed to establish a punk-inspired DIY video culture, Ed van der Elsken (1980, 1981 strived for an expressive amateur film culture. The authors propose to regarded these cases as two different experiments of participation in and through media. By conceptualising amateur film and video as counter-technologies, the discursive expectations around their democratic potential can be explored further.

    Performance advantages of the new pilot project technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities. The decision to move forward with funding usually hinges on demonstrating actual cost reductions that can be credited to budgets and thereby truly reduce O&M or capital costs. Technology enhancements, while enhancing work methods and making work more efficient, often fail to eliminate workload such that it changes overall staffing and material cost requirements. It is critical to demonstrate cost reductions or impacts on non-cost performance objectives in order for the business case to justify investment by nuclear operators. The Business Case Methodology (BCM) was developed in September of 2015 to frame the benefit side of II&C technologies to address the “benefit” side of the analysis—as opposed to the cost side—and how the organization evaluates discretionary projects (net present value (NPV), accounting effects of taxes, discount rates, etc.). The cost and analysis side is not particularly difficult for the organization and can usually be determined with a fair amount of precision (not withstanding implementation project cost overruns). It is in determining the “benefits” side of the analysis that utilities have more difficulty in technology projects and that is the focus of this methodology. The methodology is presented in the context of the entire process, but the tool provided is limited to determining the organizational benefits only. This report describes a the use of the BCM in building a business case for mobile work packages, which includes computer-based procedures and other automated elements of a work package. Key to those impacts will be identifying where the savings are

    This report presents various use case scenarios for wireless technology -including radio frequency (RF), optical, and acoustic- and studies requirements and boundary conditions in each scenario. The results of this study can be used to prioritize technology evaluation and development and in the long run help in development of a roadmap for future use of wireless technology. The presented scenarios cover the following application areas: (i) Space Vehicles (manned/unmanned), (ii) Satellites and Payloads, (iii) Surface Explorations, (iv) Ground Systems, and (v) Habitats. The requirement analysis covers two parallel set of conditions. The first set includes the environmental conditions such as temperature, radiation, noise/interference, wireless channel characteristics and accessibility. The second set of requirements are dictated by the application and may include parameters such as latency, throughput (effective data rate), error tolerance, and reliability. This report provides a comprehensive overview of all requirements from both perspectives and details their effects on wireless system reliability and network design. Application area examples are based on 2015 NASA Technology roadmap with specific focus on technology areas: TA 2.4, 3.3, 5.2, 5.5, 6.4, 7.4, and 10.4 sections that might benefit from wireless technology.

    Full Text Available Abstract Background Methods for analyzing space-time variation in risk in case-control studies typically ignore residential mobility. We develop an approach for analyzing case-control data for mobile individuals and apply it to study bladder cancer in 11 counties in southeastern Michigan. At this time data collection is incomplete and no inferences should be drawn – we analyze these data to demonstrate the novel methods. Global, local and focused clustering of residential histories for 219 cases and 437 controls is quantified using time-dependent nearest neighbor relationships. Business address histories for 268 industries that release known or suspected bladder cancer carcinogens are analyzed. A logistic model accounting for smoking, gender, age, race and education specifies the probability of being a case, and is incorporated into the cluster randomization procedures. Sensitivity of clustering to definition of the proximity metric is assessed for 1 to 75 k nearest neighbors. Results Global clustering is partly explained by the covariates but remains statistically significant at 12 of the 14 levels of k considered. After accounting for the covariates 26 Local clusters are found in Lapeer, Ingham, Oakland and Jackson counties, with the clusters in Ingham and Oakland counties appearing in 1950 and persisting to the present. Statistically significant focused clusters are found about the business address histories of 22 industries located in Oakland (19 clusters, Ingham (2 and Jackson (1 counties. Clusters in central and southeastern Oakland County appear in the 1930's and persist to the present day. Conclusion These methods provide a systematic approach for evaluating a series of increasingly realistic alternative hypotheses regarding the sources of excess risk. So long as selection of cases and controls is population-based and not geographically biased, these tools can provide insights into geographic risk factors that were not specifically

    Norms shift and emerge in response to technological innovation. One such innovation is Smart Meters - components of Smart Grid energy systems capable of minute-to-minute transmission of consumer electricity use information. We integrate theory from sociological research on social norms and privacy to examine how privacy threats affect the demand for and expectations of norms that emerge in response to new technologies, using Smart Meters as a test case. Results from three vignette experiments suggest that increased threats to privacy created by Smart Meters are likely to provoke strong demand for and expectations of norms opposing the technology and that the strength of these normative rules is at least partly conditional on the context. Privacy concerns vary little with actors' demographic characteristics. These findings contribute to theoretical understanding of norm emergence and have practical implications for implementing privacy protections that effectively address concerns of electricity users.

    This case study describes a patient presenting with a long history of excessive daydreaming which has caused her distress but is not incident to any other apparent clinical psychiatric disorders. We have treated this patient for over 10 years, and she has responded favorably to fluvoxamine therapy, stating that it helps to control her daydreaming. Our patient, and other psychotherpists, have brought to our attention other possible cases of excessive daydreaming. We examine the available literature regarding daydreaming, mind wandering, and fantasy proneness relative to current cognitive and neuroanatomical models of executive attention.

    1985-01-01

    The genus Capsicum (Fam. Solanaceae) was known to ancient cultures and was more recently historically associated with the discovery of the New World. This genus provides many species and varieties used in flavoring foods popular in the cuisines of many parts of the world. From the pungent chilli to the colorful paprika and the bell pepper, with its remarkable aroma, the genus is of great interest for its chemistry, sensory attributes, and physiological action. The Capsicums, among the spices, are second only to black pepper in trade both in volume and value. The production of the different pungency forms, the processed seasonings, and the concentrated oleoresins, through technologically advanced processes and in specified standard grades, are critically reviewed. The pungency of Capsicum fruits, its evaluation, chemical structure relationship, its increasing acceptance and preference by a variety of populations are of great research interest. The wide traditional use in the growing regions and its intense physiological effects have attracted the attention of researchers of many different disciplines. These aspects are reviewed in four sequential parts. Part I deals with history, botany, cultivation, and primary processing.

    2017-01-01

    Calcium phosphate (CaP) bioceramics are widely used in the field of bone regeneration, both in orthopedics and in dentistry, due to their good biocompatibility, osseointegration and osteoconduction. The aim of this article is to review the history, structure, properties and clinical applications of these materials, whether they are in the form of bone cements, paste, scaffolds, or coatings. Major analytical techniques for characterization of CaPs, in vitro and in vivo tests, and the requirements of the US Food and Drug Administration (FDA) and international standards from CaP coatings on orthopedic and dental endosseous implants, are also summarized, along with the possible effect of sterilization on these materials. CaP coating technologies are summarized, with a focus on electrochemical processes. Theories on the formation of transient precursor phases in biomineralization, the dissolution and reprecipitation as bone of CaPs are discussed. A wide variety of CaPs are presented, from the individual phases to nano-CaP, biphasic and triphasic CaP formulations, composite CaP coatings and cements, functionally graded materials (FGMs), and antibacterial CaPs. We conclude by foreseeing the future of CaPs. PMID:28772697

    Full Text Available Digital technologies have the potential to enable history teachers to engage student learning, meet diverse learning styles, present a diversity of perspectives, and foster historical inquiry. Pre-service teachers entering today’s Canadian faculties of education are surrounded by more technology than their predecessors. But are they equipped with requisite knowledge and strategies to integrate these technologies effectively into their classrooms? This exploratory study used a cross-sectional survey to investigate pre-service teachers’ experiences with digital technologies in relation to teaching history. By doing so it provides a context for further research into the pedagogical impacts of integrating digital technologies into history classrooms.

    Genome-wide association studies (GWAS) of schizophrenia have yielded more than 100 common susceptibility variants, and strongly support a substantial polygenic contribution of a large number of small allelic effects. It has been hypothesized that familial schizophrenia is largely a consequence of inherited rather than environmental factors. We investigated the extent to which familiality of schizophrenia is associated with enrichment for common risk variants detectable in a large GWAS. We analyzed single nucleotide polymorphism (SNP) data for cases reporting a family history of psychotic illness (N = 978), cases reporting no such family history (N = 4,503), and unscreened controls (N = 8,285) from the Psychiatric Genomics Consortium (PGC1) study of schizophrenia. We used a multinomial logistic regression approach with model-fitting to detect allelic effects specific to either family history subgroup. We also considered a polygenic model, in which we tested whether family history positive subjects carried more schizophrenia risk alleles than family history negative subjects, on average. Several individual SNPs attained suggestive but not genome-wide significant association with either family history subgroup. Comparison of genome-wide polygenic risk scores based on GWAS summary statistics indicated a significant enrichment for SNP effects among family history positive compared to family history negative cases (Nagelkerke's R(2 ) = 0.0021; P = 0.00331; P-value threshold history positive compared to family history negative cases (0.32 and 0.22, respectively; P = 0.031). We found suggestive evidence of allelic effects detectable in large GWAS of schizophrenia that might be specific to particular family history subgroups. However, consideration of a polygenic risk score indicated a significant enrichment among family history positive cases for common allelic effects. Familial illness might, therefore, represent a more heritable form of

    Knowledge of organizational history is important for recognizing patterns in effective management and understanding how organizations respond to internal and external challenges. This cross-case analysis of 12 histories of pioneering nonprofit human service organizations contributes an important longitudinal perspective on organizational history, complementing the cross-sectional case studies that dominate the existing research on nonprofit organizations. The literature on organizational growth, including lifecycle models and growth management, is reviewed, along with the literature on organizational resilience. Based on analysis of the 12 organizational histories, a conceptual model is presented that synthesizes key factors in the areas of leadership, internal operations, and external relations that influence organizational growth and resilience to enable nonprofit organizations to survive and thrive over time. Both cross-sectional and longitudinal examples from the organizational histories illustrate the conceptual map. The paper concludes with a discussion of directions for future research on nonprofit organizational history.

    The association between olmesartan and an enteropathy histologically indistinguishable from untreated celiac disease has recently been described. However, pathogenetic mechanisms leading to villous atrophy, prevalence, natural history and genetic background of this condition have not yet been defined. We describe here two cases of olmesartan-associated enteropathy and discuss some aspects of the natural history of this condition. In both patients, an infectious episode seems to have triggered the severe malabsorption syndrome which led them to hospitalization. High titer positive antinuclear antibodies with homogeneous pattern were found. Our reports add to a growing body of evidence suggesting that olmesartan-associated enteropathy should be considered in the presence of villous atrophy and negative celiac serology and in the diagnostic algorithm of non-responsive celiac disease.

    Knowledge management is paramount nowadays. In order to enable the members of an organization to deal with their current situations effectively it is mandatory to know and enhance its intellectual capital. Managing the organization knowledge is important to the extent that it allows and reinforce its mission (what we are trying to accomplish?), and performance (how do we deliver the results?). As a result of a knowledge management effort, the organization can create value for itself and for society as a whole. In this paper, we argue that a technology developed at a research institute and transferred to an industry is knowledge to be managed in order to create value, both for the society and for the Institute. In order to manage such knowledge, it is proposed an approach to enhance the value creation potential of a technology transfer. This paper propose an investigation to expand the understanding on how a public research institute and a private firm could introduce their value creation wishes into a technology transfer agreement in a way to reflect and provide the realization of those wishes. It is proposed that, from the identification of the organizations expectations it is possible to infer which agreement attributes will contribute to that value creation and to establish satisfactory agreement configurations. These configurations have the potential to generate those consequences, given that, through the transfer, each organization seeks to increase potential benefits and to reduce potential sacrifices. Supported by exchange flow and value creation models, by the knowledge management and the means-end theory, an approach to increase the value creation potential of a technology transfer is proposed. Evidences from a case study sustain the proposed approach. The case study unity is the Instituto de Engenharia Nuclear, a public research institute. (author)

    The installation of liners for vertical barriers is difficult and has been a learning experience for every contractor making the attempt. Soil stratigraphy and hydrogeologic conditions can vary over short distances, creating a variety of problems. This is particularly so when working near landfills and documentation of the as-built condition is poor. Successful installation requires detailed planning and knowledge of what to expect, as well as alternate plans for potential problems. Several successful methods of panel connection will be presented as well as a variety of installation techniques. Project case histories will be reviewed, highlighting the challenges associated with specific construction techniques.

Applies them technology lipid colloidal (TLC) which consists of the combination of particles of hydrocolloid (carboxymethylcellulose) with lipid components. Products with a technology designed for every moment of healing. Show our experience in the use of products with TLC in patients with ulcers of different etiologies. The following products depending on the case have been used to treat: UrgoTul Absorb Border, Urgoclean (rope or plate), UrgoStart, UrgoK2 and UrgoK2 LITE. These products were applied in patients presenting four different etiologies of ulcer: hypertensive, traumatic, venous and ischemic ulcer. The use of Urgoclean rope favored cleaning the bed ulceral and applied Urgoclean plate with reinforced alginate to control the abundant exudates, with coverage of UrgoTul ABsorb Border. Once clean beds pass UrgoStart and at all times UrgoK2 bandage, cases that required compressive therapy. Intolerance to that kind of compression applied to patients presenting bandage UrgoK2 LITE (which tolerated without problem) which significantly reduced edema, favoring the control of exudate. Patients with ulcer of long evolution, at the start were reluctant to the application of new technologies, but after the first cures and sensing a good evolution, we get their confidence and commitment to the resolution. Are displayed clinical cases of different etiologic and personal contexts that an integral and interdisciplinary approach together with the application of products with TLC, managed to solve the problem.

    Data on heredity, risk factors and comorbidity in microscopic colitis, encompassing collagenous colitis (CC) and lymphocytic colitis (LC), are limited. The aim was to carry out a case-control study of family history, childhood circumstances, educational level, marital status, smoking and comorbidity in microscopic colitis. A postal questionnaire was sent in 2008-2009 to microscopic colitis patients resident in Sweden and three population-based controls per patient, matched for age, sex and municipality. Some 212 patients and 627 controls participated in the study. There was an association with a family history of microscopic colitis in both CC [odds ratio (OR): 10.3; 95% confidence interval (CI): 2.1-50.4, P=0.004] and LC (OR not estimated, P=0.008). Current smoking was associated with CC [OR: 4.7; 95% CI: 2.4-9.2, Pmicroscopic colitis indicates that familial factors may be important. The association with a history of UC should be studied further as it may present new insights into the pathogenesis of microscopic colitis and UC.

    Jejunal diverticulosis is a rare, acquired pathology of the small bowel. While most patients are asymptomatic, the condition is difficult to diagnose. It may present with chronic abdominal pain, diarrhoea, bloating and complications including malabsorption, diverticulitis, bleeding, intestinal obstruction or perforation. This is a case presentation of a 27-year-old woman with a history of necrotising enterocolitis (NEC) requiring surgical resection as a premature newborn who presented with recurrent abdominal pain and was found to have several small bowel diverticula intraoperatively. She underwent resection with complete resolution of symptoms over a 2-year follow-up. This is the first case report to suggest that small bowel diverticular disease as a long-term complication of NEC may result in chronic morbidity in long-term survivors.

    Coal seam methane is a significant and emerging source of energy that can be found in Australia, western Canada, the United States, China and India. However, the extraction of methane from coal seams has one particular problem whereby, in many cases, large volumes of water with high levels of dissolved salts are produced along with the gas. This produced water poses an environmental liability, but with proper treatment can be converted into an asset. This paper discussed the use of an integrated membrane system (IMS) consisting of microfiltration coupled with reverse osmosis filtration. A case history at Origin Energy was evaluated where pilot testing was first conducted and later followed by a commercial installation treating nine million liters per day, creating a purified water product that can be used for industrial processes as well as irrigation or discharge into the environment. The paper also presented lessons learned from the pilot phase and explained the experience of the full scale operation demonstrating the advantages of this newly applied technology for coal seam methane production. The IMS system has met Origin Energy's requirements for producing high quality water, and has continued to operate effectively, producing treated water that is well within the Queensland Environmental Protection Agency's guidelines. 6 refs., 1 tab., 11 figs.

    2015-11-01

    Full Text Available The liminal zone where a city meets ‘the water’s edge’ is a place of heightened sensory experiences. In Australia, these settings have been continually reshaped and experienced, individually and collectively, both before and after European settlement, and so they provide a physical domain for reinterpreting Australian history. In Perth, Western Australia, at the turn of the twentieth century, two recreational buildings on the foreshore, the Perth City Baths (1898–1914 and the Water Chute (1905–unknown, promoted new aquatic leisure practices that provided heightened sensory experiences of the Swan River and the city foreshore. These buildings are examined from the perspective of ‘sensory history’, an alternative form of cultural and environmental analysis that has been garnering interest from a range of disciplines over the past several decades (see, for example, the work of Constance Classen, Alain Corbin, David Howes and Mark M Smith. Sensory history seeks to reveal through historical inquiry the informative and exploratory nature of the senses in specific contexts. The potential value of sensory history to studies of built and natural environments lies in drawing attention away from the overweening and frequently generalising dominance of ‘the visual’ as a critical category in humanities research. The case studies explore how evolving swimming practices at the City Baths and ‘shooting the chutes’ at the Water Chute provided novel, exciting and sometimes unpleasant haptic and olfactory experiences and consider how changing forms of recreation allowed for broadly sensuous rather than primarily visual experiences of the foreshore and Swan River. These case studies are part of a larger body of research that seeks to ‘make sense’ of the Perth foreshore and, more broadly, Australian urban waterfronts as sites of varied and evolving sensory experience.

These sites were carefully investigated in 1978 and 1979 by using standard penetration test (SPT) and cone penetration test (CPT) equipment; however, the CPT measurements are obsolete because of the now nonstandard cone that was used at the time. In 2007, a modern cone was mobilized to retest 18 selected sites that are particularly important because of the intense ground shaking they sustained despite their high fines content and/or because the site did not liquefy. Of the sites reinvestigated and carefully reprocessed, 13 were considered accurate representative case histories. Two of the sites that were originally investigated for liquefaction have been reinvestigated for cyclic failure of fine-grained soil and removed from consideration for liquefaction triggering. The most important outcome of these field investigations was the collection of more accurate data for three nonliquefaction sites that experienced intense ground shaking. Data for these three case histories is now included in an area of the liquefaction triggering database that was poorly populated and will help constrain the upper bound of future liquefaction triggering curves. ?? 2011 American Society of Civil Engineers.

    In this evidence-based case report, we studied the clinical question: Is a positive family history of acute otitis media (AOM) predictive for recurrent acute otitis media (rAOM) in children between zero and two years of age? The search yielded 3178 articles, of which only two were relevant and had a high validity regarding our clinical question. Neither of these two studies provided the final answer to our clinical question because they did not report stratified absolute risks for a positive family history. Fortunately, we were able to study the absolute risks in one of the two studies. The absolute risk of rAOM without distinguishing family history was 33 percent; the risk was 27 percent for children without a family history and 45 percent for children with a positive family history. Family history increases the absolute risk, but not in a way that it will help to predict rAOM accurately.

    The sometimes large round-to-round variability observed in accelerated environmental testing, plus difficulties in quantifying the environmental histories of a given round suggest the need for nondestructive rapid tests of munitions to supplement lifetime prediction models in quality assurance of munitions. Technologies are being developed for reagent strips which can be affixed to rounds and which will visually indicate the presence and extent of nitroester migration by a visible color change. A solid state adaptation of a modified Griess reagent develops a red-purple color in the presence of nitroesters. Performance of current designs tested in the laboratory suggest a short-term (ca. one month) single usage. Dielectric capacitance is a promising means for rapid, nondestructive moisture determinations using a portable battery-powered instrument. Laboratory studies with a modified, inexpensive, commercial device have demonstrated fast (a few seconds) detection of case wall moisture content.

    2003-01-01

    A successful business will be one that has processes in place to run that business. Creating processes, reengineering processes, and continually improving processes can be accomplished through extensive modeling. Casewise(R) Corporate Modeler(TM) CASE is a computer aided software engineering tool that will enable the Technology Transfer Department (TT) at NASA Marshall Space Flight Center (MSFC) to capture these abilities. After successful implementation of CASE, it could then go on to be applied in other departments at MSFC and other centers at NASA. The success of a business process is dependent upon the players working as a team and continuously improving the process. A good process fosters customer satisfaction as well as internal satisfaction in the organizational infrastructure. CASE provides a method for business process success through functions consisting of systems and processes business models; specialized diagrams; matrix management; simulation; report generation and publishing; and, linking, importing, and exporting documents and files. The software has an underlying repository or database to support these functions. The Casewise. manual informs us that dynamics modeling is a technique used in business design and analysis. Feedback is used as a tool for the end users and generates different ways of dealing with the process. Feedback on this project resulted from collection of issues through a systems analyst interface approach of interviews with process coordinators and Technical Points of Contact (TPOCs).

  19. Vulnerabilities to Rock-Slope Failure Impacts from Christchurch, NZ Case History Analysis

    Rock-slope failures during the 2010/11 Canterbury (Christchurch), New Zealand Earthquake Sequence resulted in 5 fatalities and caused an estimated US$400 million of damage to buildings and infrastructure. Reducing losses from rock-slope failures requires consideration of both hazard (i.e. likelihood of occurrence) and risk (i.e. likelihood of losses given an occurrence). Risk assessment thus requires information on the vulnerability of structures to rock or boulder impacts. Here we present 32 case histories of structures impacted by boulders triggered during the 2010/11 Canterbury earthquake sequence, in the Port Hills region of Christchurch, New Zealand. The consequences of rock fall impacts on structures, taken as penetration distance into structures, are shown to follow a power-law distribution with impact energy. Detailed mapping of rock fall sources and paths from field mapping, aerial lidar digital elevation model (DEM) data, and high-resolution aerial imagery produced 32 well-constrained runout paths of boulders that impacted structures. Impact velocities used for structural analysis were developed using lumped mass 2-D rock fall runout models using 1-m resolution lidar elevation data. Model inputs were based on calibrated surface parameters from mapped runout paths of 198 additional boulder runouts. Terrestrial lidar scans and structure from motion (SfM) imagery generated 3-D point cloud data used to measure structural damage and impacting boulders. Combining velocity distributions from 2-D analysis and high-precision boulder dimensions, kinetic energy distributions were calculated for all impacts. Calculated impact energy versus penetration distance for all cases suggests a power-law relationship between damage and impact energy. These case histories and resulting fragility curve should serve as a foundation for future risk analysis of rock fall hazards by linking vulnerability data to the predicted energy distributions from the hazard analysis.

    Marchant, Gary E; Sylvester, Douglas J; Abbott, Kenneth W

    2009-01-01

    As policy makers struggle to develop regulatory oversight models for nanotechnologies, there are important lessons that can be drawn from previous attempts to govern other emerging technologies. Five such lessons are the following: (1) public confidence and trust in a technology and its regulatory oversight is probably the most important factor for the commercial success of a technology; (2) regulation should avoid discriminating against particular technologies unless there is a scientifically based rationale for the disparate treatment; (3) regulatory systems need to be flexible and adaptive to rapidly changing technologies; (4) ethical and social concerns of the public about emerging technologies need to be expressly acknowledged and addressed in regulatory oversight; and (5) international harmonization of regulation may be beneficial in a rapidly globalizing world.

    Smoking is the primary cause of lung cancer and is linked to 85% of lung cancer cases. However, how lung cancer develops in patients with smoking history remains unclear. Systems approaches that combine human protein-protein interaction (PPI) networks and gene expression data are superior to traditional methods. We performed these systems to determine the role that smoking plays in lung cancer development and used the support vector machine (SVM) model to predict PPIs. By defining expression variance (EV), we found 520 dynamic proteins (EV>0.4) using data from the Human Protein Reference Database and Gene Expression Omnibus Database, and built 7 dynamic PPI subnetworks of lung cancer in patients with smoking history. We also determined the primary functions of each subnetwork: signal transduction, apoptosis, and cell migration and adhesion for subnetwork A; cell-sustained angiogenesis for subnetwork B; apoptosis for subnetwork C; and, finally, signal transduction and cell replication and proliferation for subnetworks D-G. The probability distribution of the degree of dynamic protein and static protein differed, clearly showing that the dynamic proteins were not the core proteins which widely connected with their neighbor proteins. There were high correlations among the dynamic proteins, suggesting that the dynamic proteins tend to form specific dynamic modules. We also found that the dynamic proteins were only correlated with the expression of selected proteins but not all neighbor proteins when cancer occurred.

    Rimehaug, Tormod

    2014-01-01

    The primary aim of this paper is to illustrate the strategic and ecological nature of implementation. The ultimate aim of implementation is not dissemination but sustainability beyond the implementation effort. A case study is utilized to illustrate these broad and long-term perspectives of sustainable implementation based on qualitative analyses of a 10-year implementation effort. The purveyors aimed to develop selective community prevention services for children in families burdened by parental psychiatric or addictive problems. Services were gradually disseminated to 23 sites serving 40 municipalities by 2013. Up to 2013, only one site terminated services after initial implementation. Although many sites suspended services for shorter periods, services are still offered at 22 sites. This case analysis is based on project reports, user evaluations, practitioner interviews, and service statistics. The paper focuses on the analyses and strategies utilized to cope with quality decay and setbacks as well as progress and success in disseminating and sustaining the services and their quality. Low-cost multilevel strategies to implement services at the community level were organized by a prevention unit in child psychiatry, supervised by a university department (purveyors). The purveyors were also involved in national and international collaboration and development. Multilevel strategies included manualized intervention, in-practice training methods, organizational responsibility, media strategies, service evaluation, staff motivation maintenance, quality assurance, and proposals for new law regulations. These case history aspects will be discussed in relation to the implementation literature, focusing on possible applicability across settings.

    Hospital-based case control studies have found family history of herpes zoster (HZ) was associated with risk of HZ, but the role of family history is not fully examined for other HZ-associated outcomes such as recurrent HZ, occurrence of postherpetic neuralgia (PHN), and HZ with different pain severities. We conducted a population-based matched case control study. HZ cases that occurred during December 1, 2011 to November 30, 2012 were identified by face-to-face interview with all residents of eight selected communities/villages from three districts of Beijing, China. Medical records were reviewed for those who sought healthcare for HZ. For each case-patient, three, age-matched controls (±5 years) without HZ were enrolled from the same community/village of the matched case. Data on family history of HZ were collected by interview and only defined among first-degree relatives. A total of 227 case-patients and 678 matched controls were enrolled. Case-patients were more likely to report a family history of HZ [odds ratio (OR) =2.4, P = 0.002]. Compared with controls, association of family history decreased from HZ with PHN to HZ without PHN (OR = 6.0 and 2.3, respectively; P = 0.002 for trend), from recurrent HZ to primary HZ (OR = 9.4 and 2.2, respectively; P = 0.005 for trend), and from HZ with moderate or severe pain to HZ with mild or no pain (OR = 3.2 and 0.8, respectively; P < 0.001 for trend). Family history of HZ was associated with HZ occurrence and was more likely in HZ case-patients with PHN, recurrences, and painful HZ.

    The Waterloo Barrier{trademark} steel sheet piling (patents pending) incorporates a cavity at each interlocking joint that is flushed clean and injected with sealant after the piles have been driven into the ground to form a vertical cutoff wall. The installation and sealing procedures allow for a high degree of quality assurance and control. Bulk wall hydraulic conductivities of 10{sup -8} to 10{sup -10} cm/sec have been demonstrated at field installations. Recent case histories are presented in which Waterloo Barrier{trademark} cutoff walls are used to prevent off-site migration of contaminated groundwater or soil gases to adjacent property and waterways. Full enclosures to isolate DNAPL source zones or portions of contaminated aquifers for pilot-scale remediation testing will also be described. Monitoring data will be used to demonstrate the effectiveness of the Waterloo Barrier{trademark} in these applications.

  6. Saint Ioannis Lampadistis, the first possible case of blindness due to organic mercury poisoning in history.

    Tsakiris, Kleonikos A

    2016-09-29

    Saint Ioannis Lampadistis is a Cypriot saint of the Greek Orthodox Church, widely venerated in his island of origin. He lived during the 11th century and was blinded by ingesting contaminated fish in the mountainous area of Galata, withdrew from civil life when he was 18, and died at the age of 22. The reason for his blindness remains unknown, though it is widely attributed to an unknown poison related to the copper mines of the region. As fish is the end reservoir of organic mercury, it is quite possible that his blindness was the result of heavy metal toxicity. Organic mercury is associated with CNS atrophy and hypoplasia, and blindness is a frequent presenting symptom. While not much is known about the saint's clinical symptoms (as his ecclestiastical biography focuses on his example and miracles), organic mercury poisoning could explain his sudden loss of vision, thus possibly making him the first-recorded case of organic mercury poisoning in history.

    Full Text Available Griscelli syndrome (GS is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and the hair (silver hair, with the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes. Sixty cases of GS have been reported in the literature, but we could find no description of its oro-dental symptoms. Reye′s syndrome (RS is characterized by acute noninflammatory encephalopathy and renal and hepatic failure, while atopic dermatitis (AD is a skin disorder with an immunologic basis. The aim of this paper is to describe the oro-dental and physical findings in a girl who had been diagnosed with GS at 3.5 years of age; she also had AD as well as a history of RS at infancy. We discuss the possible relationship between the three syndromes.

    Lanska, D J; Edmonson, J M

    1990-06-01

    The suspension therapy of tabes dorsalis was introduced by Motschutkovsky in 1883, popularized by Charcot and Gilles de la Tourette in 1889, and subsequently rapidly and widely disseminated on the basis of enthusiastic case series. Dissemination was facilitated by endorsements of eminent neurologists, widespread publicity in professional journals and lay press, and the apparent simplicity and safety of the procedure. However, increasingly critical reports appeared, indicating much lower success rates, frequent postprocedure deterioration, and occasional serious complications. The disparity between early and later studies resulted from a placebo effect, from disregard of the natural history of the condition, from misdiagnosis, and from biased observation and reporting. By the end of 1890, the procedure was largely abandoned, despite proponents' attempts to modify the technique or to identify a more responsive subgroup of patients.

    2013-01-01

    This paper analyses the disparities in risks associated with biomedical technology focusing on the results of assisted reproductive technology (ART). ART among biomedical technologies transferred to Asia is a representative case that reveals in its clinical use and related scientific research the global politics of technology. This study notes the global politics at work in the recognition of and reaction to such risks. While many Asian countries aggressively pursue technological development, weak legislative and administrative regulations have created various problems and controversial cases. This study asserts that risks associated with technology are characterised as social facts not natural ones or mere 'side effects', since technological development and risk are closely intertwined.

    2006-12-01

    This paper explores the history of RES and examines major technological advances that fostered the use of this technique in the sub-glacial exploration of Antarctica. The paper will especially focus on three themes: the role played by accidental discoveries in the origins of RES; the importance of international collaboration in its technological development; and the need of establishing new technological networks in the deployment of RES apparatus during Antarctic missions. The origins of RES can be traced back to two important -albeit accidental- findings. First, during post-war US military operations in the Antarctic radio altimeters produced gross errors in height indication. Furthermore, during the IGY ionospheric research and sounding was hampered by interference due to bottom echoes. These serendipitous events helped to figure out that the Antarctic ice was transparent to certain frequencies, and therefore new radio technologies could be used to sound what lay beneath it. The establishment of the Scientific Committee on Antarctic Research (SCAR) and the Antarctic Treaty (AT) provided a new international framework vital to the development of RES technologies. This allowed researchers from different countries to come together and discuss important technological features for the first time. At a technical level, the setting up of international experiments (such as those of 1963 and 1964 in Greenland) gave an opportunity for experts from different countries to compare the performance of new RES apparatus. At a political level, the parallel debate within the AT community on the allocation of Antarctic radio frequencies helped radio engineers to work out ways to circumvent interference with radio communications. Finally, the deployment of RES equipment in Antarctic exploration relied upon a number of technological aids to improve the potential and accuracy of geophysical sounding. The use of new aircrafts, guidance systems, and computers proved vital in many

    Salvatore Lorusso

    2015-12-01

    Full Text Available Art and science, over the centuries, though starting from different positions, have very often led to the same conclusions. History, on the other hand, establishes identities that derive from our past and allows for exchanges and unity between people of different nationalities, in both a commercial and scientific context, in a world without borders, in spite of obvious contradictions related to this globalized world. The case of Italy-China bears witness to this in a significant way.A case in point is represented by the scientific collaboration between the Alma Mater University of Bologna and Zhejiang University, as well as that between the Salesian Pontifical University of Rome and Fudan University in Shanghai, Zhejiang University and the Foreign Studies University of Beijing.In the first case, the ongoing research project “Historical anamnesis, preservation and valorization of the statues of the Longxing Buddhist Temple of Qingzhou (China” is being carried out between the Department of Cultural Heritage Diagnostic Laboratory for Cultural Heritage of the University of Bologna and the Cultural Heritage Institute of Zhejiang University. In the second case, collaboration between the Salesian Pontifical University and the Chinese Universities, covers activities relating to the study of philosophy, pedagogy and Latin language and literature.The paper highlights the importance of drawing value of a cultural, conservative, social, identitary nature within the context of the holistic value of cultural heritage and respecting ethical aspects at a personal and interpersonal level, in particular, by offering young people the opportunity to enter the employment market and of which they are currently experiencing all the problematic fluctuations.

  20. Health information management using optical storage technology: case studies.

    Science.gov (United States)

    Kohn, D

    1992-05-01

    All the health care facilities examined in the case studies addressed several important organizational issues before and during the installation of their systems. All the facilities examined employee commitment. The prudent managers considered how easily their employees adapt to changes in their jobs and work environment. They considered how enthusiastic cooperation can be fostered in the creation of a liberated and reengineered office. This was determined not only by each individual's reaction to change, but also by the health care facility's track record with other system installations. For example, document image, diagnostic image, and coded data processing systems allow the integration of divergent health care information systems within complex institutions. Unfortunately, many institutions are currently struggling with how to create an information management architecture that will integrate their mature systems, such as their patient care and financial systems. Information managers must realize that if optical storage technology-based systems are used in a strategic and planned fashion, these systems can act as focal points for systems integration, not as promises to further confuse the issue. Another issue that needed attention in all the examples was the work environment. The managers considered how the work environment was going to affect the ability to integrate optical image and data systems into the institution. For example, many of these medical centers have created alliances with clinics, HMOs, and large corporate users of medical services. This created a demand for all or part of the health information outside the confines of the original institution. Since the work environment is composed of a handful of factors such as merged medical services, as many work environment factors as possible were addressed before application of the optical storage technology solution in the institutions. And finally, the third critical issue was the organization of work

    Directory of Open Access Journals (Sweden)

    Carinna Margaret Torgerson

    2014-11-01

    Full Text Available The claustrum seems to have been waiting for the science of connectomics. Due to its tiny size, the structure has remained remarkably difficult to study until modern technological and mathematical advancements like graph theory, connectomics, diffusion tensor imaging, HARDI, and excitotoxic lesioning. That does not mean, however, that early methods allowed researchers to assess micro-connectomics. In fact, the claustrum is such an enigma that the only things known for certain about it are its histology, and that it is extraordinarily well connected. In this literature review, we provide background details on the claustrum and the history of its study in the human and in other animal species. By providing an explanation of the neuroimaging and histology methods have been undertaken to study the claustrum thus far – and the conclusions these studies have drawn – we illustrate this example of how the shift from micro-connectomics to macro-connectomics advances the field of neuroscience and improves our capacity to understand the brain.

    2017-02-01

    Suspected child physical abuse, sexual abuse and neglect are not uncommon presentations. As part of the assessment of these cases, a forensic medical history may be taken. This forensic history is used not only to determine the steps necessary to address the child's wellbeing but also to direct the forensic examination. Currently, there is no clear consensus on whether or not a forensic medical history should consistently be considered an integral element within the paediatric forensic evaluation. This study examines the value derived by the medical practitioner taking a forensic medical history rather than relying on hearsay evidence when a child presents for an assessment. A retrospective review of paediatric cases seen by the Victorian Forensic Paediatric Medical Service (VFPMS) between 2014 and 2015 was undertaken. 274 forensic case reports were reviewed and the data was entered into an Excel spread sheet and analysed using chi squared tests within STATA(®). With increasing age of the child, a forensic medical history is significantly more likely to be taken. Additional information is made available to the medical practitioner what would otherwise have been provided if the medical practitioner relied only on the interview conducted by the police. Discrepancies observed between the official third parties (police or child protection) report of what a child has said and what the child says to the medical practitioner decrease with age, as do discrepancies observed between the child's version of events and a third party's (eg. parents, caregivers, friends) version of events. The study showed that by taking a forensic medical history from the child additional information can be obtained. Further, that there is a value in the examining medical practitioner taking a forensic medical history from children in cases of child physical and sexual abuse and neglect.

    The article recalls the history of the development of Fluor FDG in Brazil. Important facts that impacted this development and how this technology evolved considering a time span of more then ten years, starting from 1996 is presented in this paper. Five decisions, taken between 2004 and 2005, were selected and analyzed from the perspective of knowledge that a key decision maker has developed around the main elements of a decision - problem, objectives, alternatives, consequences, risks approach and linked decisions. Contextual aspects that influenced these decisions, such as the evolution of the technology efficiency, installation of new equipment in hospitals and the consequences associated with these decisions, such as daily production capacity, distance service and numbers of attended clients are part of this study. In conclusion, this case shows that experienced decision makers can make quality decisions when they are equipped with the appropriate information, align the relevant decisions taken over time, know how to use the right tactics at the right time and with all participants in decision making. Experienced decision makers identify opportunities where there seems to be problems, review the current strategies and visualize new strategies, prepare themselves adequately to deal with the uncertainties.

    By J OHN A. HRONES Provost, Case Institute 0/ Technology SYSTEMS have been the subject of man's study for many hundreds of years. Thus, the solar system has been the concern of the astronomer. The study of the allocation of material and human resources within the boundaries of an industrial firm or a government has been the concern of the economist. The subject of such studies have been widely known as economic systems. Medieal men have worked with the human body. Thus, man has attempted to deal with a complicated array of interconnected elements since the very earliest of recorded time. In his attcmpt to improve his understanding of physieal systems the need to concentrate on a specific kind of system, e.g., the solar system. the human body, became more imperative. However in recent years there has begun to grow and develop an increasing number of people who are working on thc development of general systems theory and analysis.

  9. ARE THE INFORMATION TECHNOLOGIES CHANGING POLITICS? CASE STUDY IN GALICIA

    2010-12-01

    Full Text Available In the industrial society, politicians had to command the language TV since the intensity of the reaction was more important than the length of the message. They had to make categorical statements. In the Information Society with information and communication technologies (TICs, this changes to a great extent due to pluralism and the fact that more people make themselves heard. Blogs appear as a way to give opinion and information, and can be considered as an alternative form of expression –blogs give different views on news ignored by the main media-. Activists, political parties, organizations and citizens use websites, blogs or wikis as a means to insist and create opinion. TICs and cooperative tools of Web 2.0 increase people’s interest in politics, individual commitment and participation and cause political mediators to disappear. This paper presents a reflection on the impact of TICs on the theory of politics, and the results of a quantitative analysis of cases from the observation of how TICs are used on the social platform “Nunca Máis”, as well as by the autonomous government Xunta de Galicia, the Parliament of Galicia and the political party Bloque Nacionalista Galego.

    Only limited data is available on the relationship between family history of laryngeal and other neoplasms and laryngeal cancer risk. We investigated the issue using data from a multicentre case-control study conducted in Italy and Switzerland between 1992 and 2009 including 852 cases with histologically confirmed laryngeal cancer and 1970 controls admitted to hospital for acute, non neoplastic conditions. Unconditional logistic regression models adjusted for age, sex, study center, education, tobacco smoking, alcohol drinking and number of siblings were used to estimate the odds ratios (ORs) of laryngeal cancer. The multivariate OR was 2.8 (95% confidence interval [CI], 1.5-5.3) in subjects reporting a first-degree relative with laryngeal cancer, as compared to subjects with no family history. The OR was higher when the relative was diagnosed before 60 years of age (OR = 3.5, 95% CI 1.4-8.8). As compared to subjects without family history, non-smokers, and moderate drinkers, the OR was 37.1 (95% CI 9.9-139.4) for current smokers, heavy drinkers, with family history of laryngeal cancer. Family history of colorectal (OR = 1.5, 95% CI 1.0-2.3) and kidney (OR = 3.8, 95% CI 1.2-12.1) cancer were also associated to an increased risk of laryngeal cancer, while no significant increase in risk was found for family history of cancer at all sites, excluding the larynx (OR = 1.1).

    The use of jargon has become very common in the healthcare field, especially in medical/dental records. Although the use of standard medical jargon can be seen as professional, efficient shorthand, a lack of awareness regarding the standard medical abbreviations and incessant and overzealous use of slang among the healthcare professionals can act as a barrier to effective communication and understanding among patients and peers. The aim of this study was to assess the acceptance and use of jargon in case history taking among clinical dental students and dental teaching faculty members of dental colleges in Ernakulam and Idukki districts of Kerala. A cross-sectional questionnaire-based survey was carried out, consisting of 15 questions, to assess the objectives of the study. The study was conducted among clinical dental undergraduate students, house surgeons, postgraduate students and teaching faculty members of five dental colleges in Ernakulam and Idukki districts, Kerala. The results were expressed as a number and percentage of response for each question and Chi-squared test was used for inferential statistical analysis. All the 549 respondents used jargon in case history taking. Approximately 22.4% of the respondents admitted that they always used jargon and 55.8% admitted of using jargon only when there was a lack of time. The majority of the respondents (71.4%) learned the jargon from their colleagues. Approximately 50% of the respondents admitted use of jargon in a history section and about 32% of the respondents in all the sections of case history taking. Approximately 74% were of the opinion that abbreviations should be permitted in case history taking. This study showed widespread use of jargon/abbreviations in case history taking among the respondents. There is a lack of knowledge regarding standard medical abbreviations. Although the majority of the respondents were comfortable with the use of jargon, the majority of the postgraduates and faculty members

    Science.gov (United States)

    Ryan, Robert W; Spetzler, Robert F; Preul, Mark C

    2009-09-01

    In this historical review the authors examine the important developments that have led to the availability of laser energy to neurosurgeons as a unique and sometimes invaluable tool. They review the physical science behind the function of lasers, as well as how and when various lasers based on different lasing mediums were discovered. They also follow the close association between advances in laser technology and their application in biomedicine, from early laboratory experiments to the first clinical experiences. Because opinions on the appropriate role of lasers in neurosurgery vary widely, the historical basis for some of these views is explored. Initial enthusiasm for a technology that appears to have innate advantages for safe resections has often given way to the strict limitations and demands of the neurosurgical operating theater. However, numerous creative solutions to improve laser delivery, power, safety, and ergonomics demonstrate the important role that technological advances in related scientific fields continue to offer neurosurgery. Benefiting from the most recent developments in materials science, current CO(2) laser delivery systems provide a useful addition to the neurosurgical armamentarium when applied in the correct circumstances and reflect the important historical advances that come about from the interplay between neurosurgery and technology.

    Primary sarcomas of the aorta are extremely uncommon. Depending on histomorphology and immunohistochemical pattern, intimal sarcomas can show angiosarcomatous differentiation. Here, we describe the case of a 60-year-old woman with a primary intimal sarcoma of the aortic arch and signs of cerebral metastatic disease as the initial manifestation. After the patient experienced the onset of severe headaches, ataxia, and left-sided weakness, magnetic resonance imaging showed several brain lesions. Histologic assessment of a brain biopsy specimen revealed a malignant tumour composed of large pleomorphic cells that were positive for pancytokeratin and CD10. Radiation to the brain did not significantly improve the patient's symptoms, and cranial computed tomography (ct) imaging revealed several metastases, indicating lack of response. Because of the patient's smoking history, the presence of central nervous system and skeletal metastases on combined positron-emission tomography and ct imaging, and the focal pan-cytokeratin positivity of the tumour, carcinoma of the lung was favoured as the primary tumour. Despite chemotherapy with cisplatin and etoposide, the patient's neurologic symptoms and general condition deteriorated rapidly, and she died within a few days. At autopsy, an undifferentiated intimal sarcoma of the aortic arch was diagnosed. The primary tumour in the aorta consisted of large pleomorphic cells. Immunohistochemical analysis of the aortic tumour and brain metastases demonstrated diffuse positivity for vimentin and p53 and focal S-100 staining. In summary, we report a challenging case of advanced intimal sarcoma of the aortic arch with brain and bone metastases at initial presentation. Our report demonstrates the difficulties in diagnosing and treating this disease, and the need for multicentre studies to accrue more patients for investigations of optimal therapy.

  5. Successful field implementation of novel cementing solution for ISC wells : case histories

    Cementation of in-situ combustion (ISC) wells is challenging since wells are frequently associated with weak and unconsolidated formation. However, cement rise up to surface is desired to prevent casing failure. Moreover, the cement sheath is also required to withstand extreme stresses due to high temperature cycling experienced during in-situ combustion process. In response to the problem of inadequate placement time and flash setting, Portland cement-silica blends were used for cementation of ISC wells in India instead of alumina cement blends. However, the use of the cement-silica blends has resulted in insufficient cement rise because of losses during cementation. The cured cement failed to contain the strength and permeability in course of ISC process causing charge of sub-surface shallower layers. This paper discussed the development and implementation of a non-alumina based thermally stable lightweight lead slurry and a ductile high temperature resistance tail slurry for mitigating these problems. The paper provided details of the study as well as four successful case histories. The cementing practice for ISC wells around the world was first described and illustrated. Next, the paper outlined the formulation of thermally stable tail slurry through laboratory studies. Slurry parameters of the tail slurry were presented, including slurry weight; thickening time; fluid loss; free fluid; and rheology. The paper also reviewed a study of compressive strength and permeability of thermal slurry; slurry parameters of the lightweight lead slurry; and study of compressive strength and permeability of lightweight thermal slurry. 8 refs., 4 tabs., 12 figs.

  6. A Case of Recurrent Skin Abscesses: A Conundrum Solved after Obtaining a Thorough Sexual History

    Directory of Open Access Journals (Sweden)

    Diego P. Peralta

    2017-01-01

    Full Text Available Background. Despite the improvement in patient-physician communication techniques, sexuality and sexual health continue to be challenging areas for discussion during a clinical encounter. Most people are not prepared to discuss sexual matters openly as it can be perceived as negative or inappropriate. Consequently, an incomplete health assessment can result in delayed diagnosis or misdiagnosis. Case Report. We present a 33-year-old woman who developed recurrent left breast abscesses. She required multiple incision and drainage procedures in the operating room followed by antimicrobial therapy. Although she always had an initial improvement with this approach, she continued to have recurrences and development of new abscesses in other body areas. The polymicrobial nature of her recurrences prompted an extensive and costly workup to determine the nature of her condition. The cause was finally elucidated when a thorough sexual history was obtained. Poor hygiene practices during her sexual encounters were considered the cause of her recurrent abscesses. After medical therapy and modification of her sexual practices, she has not developed new recurrences for more than two years. Conclusion. Discussions on sexuality and sexual health are important parts of any clinical encounter, yet frequently forgotten or avoided. Becoming aware of their importance would avoid delayed diagnosis or misdiagnosis.

  7. Single-Case Research Methods: History and Suitability for a Psychological Science in Need of Alternatives.

    Science.gov (United States)

    Hurtado-Parrado, Camilo; López-López, Wilson

    2015-09-01

    This paper presents a historical and conceptual analysis of a group of research strategies known as the Single-Case Methods (SCMs). First, we present an overview of the SCMs, their history, and their major proponents. We will argue that the philosophical roots of SCMs can be found in the ideas of authors who recognized the importance of understanding both the generality and individuality of psychological functioning. Second, we will discuss the influence that the natural sciences' attitude toward measurement and experimentation has had on SCMs. Although this influence can be traced back to the early days of experimental psychology, during which incipient forms of SCMs appeared, SCMs reached full development during the subsequent advent of Behavior Analysis (BA). Third, we will show that despite the success of SCMs in BA and other (mainly applied) disciplines, these designs are currently not prominent in psychology. More importantly, they have been neglected as a possible alternative to one of the mainstream approaches in psychology, the Null Hypothesis Significance Testing (NHST), despite serious controversies about the limitations of this prevailing method. Our thesis throughout this section will be that SCMs should be considered as an alternative to NHST because many of the recommendations for improving the use of significance testing (Wilkinson & the TFSI, 1999) are main characteristics of SCMs. The paper finishes with a discussion of a number of the possible reasons why SCMs have been neglected.

    We analyzed the relationship between cholelithiasis and cancer risk in a network of case-control studies conducted in Italy and Switzerland in 1982-2009. The analyses included 1997 oropharyngeal, 917 esophageal, 999 gastric, 23 small intestinal, 3726 colorectal, 684 liver, 688 pancreatic, 1240 laryngeal, 6447 breast, 1458 endometrial, 2002 ovarian, 1582 prostate, 1125 renal cell, 741 bladder cancers, and 21 284 controls. The odds ratios (ORs) were estimated by multiple logistic regression models. The ORs for subjects with history of cholelithiasis compared with those without were significantly elevated for small intestinal (OR=3.96), prostate (OR=1.36), and kidney cancers (OR=1.57). These positive associations were observed ≥10 years after diagnosis of cholelithiasis and were consistent across strata of age, sex, and body mass index. No relation was found with the other selected cancers. A meta-analysis including this and three other studies on the relation of cholelithiasis with small intestinal cancer gave a pooled relative risk of 2.35 [95% confidence interval (CI) 1.82-3.03]. In subjects with cholelithiasis, we showed an appreciably increased risk of small intestinal cancer and suggested a moderate increased risk of prostate and kidney cancers. We found no material association with the other cancers considered.

  9. Practice versus theory: tenth-century case histories from the Islamic Middle East.

    Science.gov (United States)

    Alvarez-Millan, C

    2000-08-01

    Medicine and disease in medieval Islam have thus far been approached through theoretic medical treatises, on the assumption that learned medical texts are a transparent account of reality. A question yet to be sufficiently explored is the extent to which the ideas and theoretical principles they contain were actually carried out in practice. This paper deals with the description of diseases occurring in a tenth-century Casebook (Kitāb al-Tajārib) by Abū Bakr Muhammad ibn Zakarīyā' al-Rāzi (known to Europeans as Rhazes)-the largest and oldest collection of case histories, so far as is known, in medieval Islamic medical literature. Since the author was a prolific medical writer, this study also includes a review of his medical and therapeutic principles dealing with eye diseases, as described in his learned treatises, and a comparison with those therapies actually employed in his everyday practice, as exemplified by the Casebook. The comparative analysis shows that the medical knowledge and the therapeutic advice so meticulously described in theoretical works were not paralleled in the physician's medical performance. On the contrary, it appears that learned treatises served other purposes than determining medical practice.

    This study aimed to evaluate the demographic, clinical, and epidemiological features of pityriasis rosea (PR) in a cohort of 46 children in Yozgat, a city in the Central Anatolia Region of Turkey. Forty-six children with PR were monitored at regular intervals (1, 2, 4, and 12 weeks) for 3 months from the time of diagnosis. A complete evaluation of the patient was performed at each visit. The average age of patients at time of diagnosis was 12 ± 3.9 years. Cases were most common in the winter (rainy, snowy months; n = 14, 31%). Fifteen patients had a medical history significant for the presence of upper respiratory tract infection, while skin PR manifestations were preceded by drug intake in a second group of 15 patients. The presence of a herald patch was observed in 78.3% of patients, most frequently on the trunk (n = 23). Pruritus occurred in 75% of patients. Median PR duration was 3 weeks (range: 1-20 weeks). The course of PR is similar in Turkish children and adults. The high prevalence of pruritus in children with PR in Turkey was also significant. Further evaluation of this finding comparing adults and children is now required.

    Renaissance painters used a number of inorganic color materials. The development of mineralogy as a discipline opened a new discourse on mineral pigments. Agricola and other naturalists were familiar with the contemporary writings on art technology, but their focus was different. Therefore, the exchange of knowledge between these two color worlds remained selective. One possible meeting point was the Kunstkammer where the study of natural objects and materials was combined with an interest in the manual execution of a painting.

    Sake is an alcoholic beverage of Japan, with a tradition lasting more than 1,300 years; it is produced from rice and water by fermenting with the koji mold Aspergillus oryzae and sake yeast Saccharomyces cerevisiae. Breeding research on sake yeasts was originally developed in Japan by incorporating microbiological and genetic research methodologies adopted in other scientific areas. Since the advent of a genetic paradigm, isolation of yeast mutants has been a dominant approach for the breeding of favorable sake yeasts. These sake yeasts include (a) those that do not form foams (produced by isolating a mutant that does not stick to foams, thus decreasing the cost of sake production); (b) those that do not produce urea, which leads to the formation of ethyl carbamate, a possible carcinogen (isolated by positive selection in a canavanine-, arginine-, and ornithine-containing medium); (c) those that produce an increased amount of ethyl caproate, an apple-like flavor (produced by isolating a mutant resistant to cerulenin, an inhibitor of fatty-acid synthesis); and (d) those that produce a decreased amount of pyruvate (produced by isolating a mutant resistant to an inhibitor of mitochondrial transport, thus decreasing the amount of diacetyl). Given that sake yeasts perform sexual reproduction, sporulation and mating are potent approaches for their breeding. Recently, the genome sequences of sake yeasts have been determined and made publicly accessible. By utilizing this information, the quantitative trait loci (QTLs) for the brewing characteristics of sake yeasts have been identified, which paves a way to DNA marker-assisted selection of the mated strains. Genetic engineering technologies for experimental yeast strains have recently been established by academic groups, and these technologies have also been applied to the breeding of sake yeasts. Sake yeasts whose genomes have been modified with these technologies correspond to genetically modified organisms (GMOs

  2. Seismic response in archaeological areas: the case-histories of Rome

    1999-03-01

    Rome is affected by earthquakes associated to three different seismogenic districts: the Central Apennines area, the Colli Albani volcanic area and the Roman area. The major effects were exclusively due to Apennine seismicity and reached in some cases felt intensities up to VII-VIII degree (MCS scale). The predominant role in the damage distribution seems to be played by the local geological conditions. The historical centre of the city is characterized by the presence of two geomorphologic domains: the alluvial plain of Tiber river and the topographic relieves of Roman Hills, where tradition indicates the first site of the city foundation. In particular, the right river side is characterized by the outcropping of the regional bedrock along the Monte Mario-Gianicolo ridge, while the eastern relieves are the remnants of the Sabatini and Albani volcanic plateau, deeply eroded by the Tiber river and its tributaries during the last glacial low-stand (Würm). These domains are characterized by a large difference in seismic response, due to the high impedance contrast between Holocene coarse deposits filling the Tiber Valley and sedimentary and volcanic Plio-Pleistocene units. Seismic damage observed in 150 monuments of downtown Rome was indicating a significant concentration on alluvial recent deposits. This result was confirmed by the geographical distribution of conservation and retrofitting activities subsequent to main earthquakes, mostly related to local geological conditions. The cases of Marcus Aurelius' Column and Colosseum confirmed the influence of the Holocene alluvial network in local seismic response. During 2500 years of history, the monuments of Rome have `memorized' the seismic effects of historical earthquakes. In some cases, the integration of historical and geological research and macroseismic observations may provide original and useful indications to seismologists to define the seismic response of the city. Local site effects represent a serious

  3. Four steps in the history of museum technologies and visitors' digital participation

    Directory of Open Access Journals (Sweden)

    Jørgen Riber Christensen

    2010-12-01

    Full Text Available The hypothesis of this article is that the authentic and auratic exhibited objects in museums enter into a dialogue with surrounding paratexts. The paratexts anchor and change the meaning of the exhibited object in the museum context. Recent years have indicated a tendency for museum paratexts to grow increasingly allographic, i.e., visitors generate them both in situ and online as a part of Web 2.0 participation. The verification and documentation of this hypothesis are partly empirical, partly historical. The empirical research consists of an examination of the exhibition and display technologies used today in three different museums and galleries: the Bode Museum in Berlin, the Victoria and Albert Museum and Dr. Johnson's House in London.    The historical verification and documentation in this article describe four steps in the development of exhibition technologies: the Boydell Shakespeare Gallery (1789-1805, the post-photographic museum (the 1850s, audio guides, as well as a special focus on how museum paratexts have become independent today in its digital and participatory form. In this way, the article sketches the historical development of curating towards the digital and paratextual participation of visitors and audience. Here the argumentation is based on how the displayed object creates signification in its position between its autonomy and its contexts. The following display technologies are described and analysed: stipple engraving, photography, the audio guide, and the interactive, digital Anota pen and its Internet server.    In conclusion, the article asks where the place of signification or meaning of the exhibited object has moved to in the face of the increased degree of visitor participation. The tentative answer is that the signification generating process has moved away from the historical context of the object and towards the contemporary world of the visitor. The article connects this change in cultural discourse

    Recumbent bicycles have never truly been associated with international cycling. Conventional safety (upright) bicycles have long been at the center of the cycling world, for both sport and transportation. This is despite the fact that recumbent bicycles are faster, more comfortable, and more efficient than the upright bicycles. The aim of this article is to explain the historical and social perspectives that led to the rejection of the recumbent bicycle by utilizing the theory of Social Construction of Technology (SCOT) and Bijker's two power theory, providing a contrast with the adoption of the safety bicycle.

    Coeliac disease is a common enteropathy characterized by an increased mortality mainly due to its complications. The natural history of complicated coeliac disease is characterised by two different types of course: patients with a new diagnosis of coeliac disease that do not improve despite a strict gluten-free diet (type A cases) and previously diagnosed coeliac patients that initially improved on a gluten-free diet but then relapsed despite a strict diet (type B cases). Our aim was to study the prognosis and survival of A and B cases. Clinical and laboratory data from coeliac patients who later developed complications (A and B cases) and sex- and age-matched coeliac patients who normally responded to a gluten-free diet (controls) were collected among 11 Italian centres. 87 cases and 136 controls were enrolled. Complications tended to occur rapidly after the diagnosis of coeliac disease and cumulative survival dropped in the first months after diagnosis of complicated coeliac disease. Thirty-seven cases died (30/59 in group A, 7/28 in group B). Type B cases presented an increased survival rate compared to A cases. Complicated coeliac disease is an extremely serious condition with a high mortality and a short survival. Survival depends on the type of natural history.

    The International Society for Technology Assessment in Health Care (ISTAHC) was formed in 1985. It grew out of the increasing awareness of the international dimensions of health technology assessment (HTA) and the need for new communication methods at the international level. The main function of ISTAHC was to present an annual conference, which gradually grew in size, and also to generally improve in quality from to year. ISTAHC overextended itself financially early in the first decade of the 2000s and had to cease its existence. A new society, Health Technology Assessment international (HTAi), based on many of the same ideas and people, grew up beginning in the year 2003. The two societies have played a large role in making the field of HTA visible to people around the world and providing a forum for discussion on the methods and role of HTA.

  14. Pipeline coatings and joint protection: a brief history, conventional thinking and new technologies

    Energy Technology Data Exchange (ETDEWEB)

    Buchanan, Robert [Canusa-CPS, Toronto, ON (Canada)

    2003-07-01

    Pipelines have been in use since oil was discovered and the need to move it efficiently from the well head to secondary transportation, refinery or market was first realized. Early pipelines were obviously crude, but corrosion was understood as being a problem which resulted in the need for corrosion preventive coatings. As coatings technology developed, pipeline coatings became better and longer lasting but also needed to advance as pipeline operating conditions became more severe. High performance pipeline coatings, such as the 3-layer polyethylene (3LPE) and, more recently, multi-layer polypropylene (MLPP), have been developed to meet the more demanding applications in today's market. Coatings are generally applied under well controlled factory conditions but weld joint systems need to be applied by contractors under unpredictable field conditions and yet provide performance and quality consistent with plant applied coatings. Polyethylene heat-shrinkable sleeves are the most commonly used corrosion protection system for field joints on 3LPE coated pipelines today due to their compatibility, ease of application, reliability and extensive track record. However, there has been an absence of a more universally accepted field joint solution for MLPP coated pipelines. This paper ultimately describes the evolution and development of the latest generation of heat-shrinkable sleeves for 3LPE plus a breakthrough technology in MLPP field joint coatings that has been tested, specified and successfully used in the field on many global projects by leading engineers and contractors, including in Brazil.

  15. A history of deep brain stimulation: Technological innovation and the role of clinical assessment tools

    Science.gov (United States)

    2013-01-01

    Deep brain stimulation involves using a pacemaker-like device to deliver constant electrical stimulation to problematic areas within the brain. It has been used to treat over 40,000 people with Parkinson’s disease and essential tremor worldwide and is currently undergoing clinical trials as a treatment for depression and obsessive–compulsive disorder. This article will provide an historical account of deep brain stimulation in order to illustrate the plurality of interests involved in the development and stabilization of deep brain stimulation technology. Using Latour’s notion of immutable mobiles, this article will illustrate the importance of clinical assessment tools in shaping technological development in the era of medical device regulation. Given that such tools can serve commercial and professional interests, this article suggests that it is necessary to scrutinise their application in research contexts to ensure that they capture clinical changes that are meaningful for patients and their families. This is particularly important in relation to potentially ethically problematic therapies such as deep brain stimulation for psychiatric disorders.

    2003-04-01

    Early wind turbines used for performing mechanical work (pumping, grinding and cutting) optimized aerodynamics by being allowed to run at variable speed. Some of the earliest DC electric wind turbines were allowed to run at variable speed. With the advent of grid-connected AC turbines, rotational speeds were limited in order to control the wind turbine AC frequency output to equal the grid frequency. With the advent of semiconductor devices, attempts began as early as the 1970s to allow variable-speed operation of large-scale turbines. The introduction of a new generation of high-voltage, high-speed power electronic components allows a wide range of variable-speed operation for very-large-scale machines. Over the past 30 years a number of designs have been tested, a few of which have entered commercial operation. A number of these designs and their histories are described. A detailed description of a wide range of electrical methods for allowing variable-speed operation is provided.

  3. Space-Time Analysis of Testicular Cancer Clusters Using Residential Histories: A Case-Control Study in Denmark

    2015-01-01

    Though the etiology is largely unknown, testicular cancer incidence has seen recent significant increases in northern Europe and throughout many Western regions. The most common cancer in males under age 40, age period cohort models have posited exposures in the in utero environment or in early childhood as possible causes of increased risk of testicular cancer. Some of these factors may be tied to geography through being associated with behavioral, cultural, sociodemographic or built environment characteristics. If so, this could result in detectable geographic clusters of cases that could lead to hypotheses regarding environmental targets for intervention. Given a latency period between exposure to an environmental carcinogen and testicular cancer diagnosis, mobility histories are beneficial for spatial cluster analyses. Nearest-neighbor based Q-statistics allow for the incorporation of changes in residency in spatial disease cluster detection. Using these methods, a space-time cluster analysis was conducted on a population-wide case-control population selected from the Danish Cancer Registry with mobility histories since 1971 extracted from the Danish Civil Registration System. Cases (N=3297) were diagnosed between 1991 and 2003, and two sets of controls (N=3297 for each set) matched on sex and date of birth were included in the study. We also examined spatial patterns in maternal residential history for those cases and controls born in 1971 or later (N= 589 case-control pairs). Several small clusters were detected when aligning individuals by year prior to diagnosis, age at diagnosis and calendar year of diagnosis. However, the largest of these clusters contained only 2 statistically significant individuals at their center, and were not replicated in SaTScan spatial-only analyses which are less susceptible to multiple testing bias. We found little evidence of local clusters in residential histories of testicular cancer cases in this Danish population. PMID

    Here, we report three cases of moyamoya disease with a history of Kawasaki disease. A 33-year-old man was found to have stenotic lesions of the internal carotid arteries(ICAs)on both sides at a nearby hospital where he visited complaining of headache and lisping. He had received immunoglobulin therapy for Kawasaki disease at the ages of 1, 2, and 6 years. MRI showed only a chronic ischemic lesion in the white matter. Angiography showed occlusion at the terminal portion of the ICAs on both sides. He was diagnosed with moyamoya disease, but as he had no symptoms and preserved cerebral blood flow (CBF), he was kept under observation. An 8-year-old boy was diagnosed with moyamoya disease and underwent right encephaloduroarteriosynangiosis at a nearby hospital. He had received immunoglobulin therapy for Kawasaki disease at the age of 1 year. His ischemic symptoms worsened. Although MRI detected no apparent ischemic lesion, angiography revealed severe stenosis at the terminal portions of the ICAs on both sides, and 123I-IMP SPECT showed CBF impairment. Bilateral direct bypass was performed. His father was subsequently also diagnosed with moyamoya disease. A 4-year-old girl with epilepsy was diagnosed with moyamoya disease at a nearby hospital. She had been treated with aspirin for Kawasaki disease at the age of 1 year. MRI detected no remarkable ischemic lesions, but angiography revealed mild stenosis at the terminal portions of the ICAs on both sides. Five months later, her ischemic symptoms were worsening with progressing stenotic lesions, and she underwent bilateral direct bypass.

    2015-01-01

    This paper presents a case history study on the geologic investigation and numerical modeling of a reactivated landslide in the County of Santa Clara, California to identify the failure mechanism. The landslide occurred on an approximately 18.3-m high, north-facing slope during March 2011. The land-slide measured about 33.5 m in width and about 51.8 m in length. Along the toe of the slope, a residential structure with a swimming pool was built on a cut and fill pad and there are several other structures present along the western side of the pad. The landslide occurred immediately to the south of the residential building and moved northward between the County Road A and the house’s side yard. The movement of the landslide resulted in damaging the west-bound traffic lane of County Road A and encroached onto the paved driveway for the residential property. An investigation was performed to identify the failure mechanism of the landslide to conclude whether Road A re-alignment by the County or prominent cutting performed along the lower portion of the slope by the homeowner during 2000 through 2004 contributed to the reactivation of the old landslide deposit. The investigation included site reconnaissance, reviewing available published geologic information, reviewing site-specific geologic and geotechnical data developed by other consultants, and performing numerical modeling. The outcomes of the investigation indicate that the primary causation for the reactivation and failure of the subject pre-existing landslide is the prominent cutting performed along the lower portion of the slope during 2000 through 2004 and water tank cut bench. The Road A re-alignment did not contribute to the reactivation of the old landslide deposit.

    Low birth weight (LBW; below 2500 grams) is a general risk factor for a variety of neurodevelopmental difficulties. However, these children may remain more vulnerable to neurologic and environmental insults occurring years later. This prospective case series reports on children who sustained a mild, moderate, or severe traumatic brain injury (TBI) in middle childhood but who had also been born with birth weights below 2500 grams. PARTICIPANTS were 14 children with mild, moderate, or severe traumatic brain injury (TBI), 5 of whom had birth weights under 2500 grams (LBW) and 9 children with normal birth weight (NBW). All participants were drawn from a larger study on the long-term cognitive and behavioral impact of pediatric TBI and were matched on age, estimated socioeconomic status (SES), and severity of TBI (with NBW children actually having a slightly worse overall injury severity). At baseline, both groups exhibited similar scores on WJ-R Letter Word Identification and Calculations, Tower of London number solved, and CVLT-C total correct. Baseline group differences were observed on the CELF-III Formulated Sentences (NBW > LBW) and on the VABS Adaptive Behavior Composite and Socialization subdomain (LBW > NBW). Over 2 years, relative to the NBW group, the LBW group evidenced declines on both WJ-R subtests, CVLT-C total correct, CELF-III Formulated Sentences, and VABS Adaptive Behavior Composite and Socialization. Although preliminary in nature due to small sample size, findings suggest a history of LBW influences the recovery trajectory following childhood TBI. Academic and adaptive functioning and verbal memory appeared particularly affected.

    Full Text Available This paper presents a case history study on the geologic investigation and numerical modeling of a reactivated landslide in the County of Santa Clara, California to identify the failure mechanism. The landslide occurred on an approximately 18.3-m high, north-facing slope during March 2011. The landslide measured about 33.5 m in width and about 51.8 m in length. Along the toe of the slope, a residential structure with a swimming pool was built on a cut and fill pad and there are several other structures present along the western side of the pad. The landslide occurred immediately to the south of the residential building and moved northward between the County Road A and the house's side yard. The movement of the landslide resulted in damaging the west-bound traffic lane of County Road A and encroached onto the paved driveway for the residential property. An investigation was performed to identify the failure mechanism of the landslide to conclude whether Road A re-alignment by the County or prominent cutting performed along the lower portion of the slope by the homeowner during 2000 through 2004 contributed to the reactivation of the old landslide deposit. The investigation included site reconnaissance, reviewing available published geologic information, reviewing site-specific geologic and geotechnical data developed by other consultants, and performing numerical modeling. The outcomes of the investigation indicate that the primary causation for the reactivation and failure of the subject pre-existing landslide is the prominent cutting performed along the lower portion of the slope during 2000 through 2004 and water tank cut bench. The Road A re-alignment did not contribute to the reactivation of the old landslide deposit.

    This case history discusses the exploration methods used at the Momotombo Geothermal Field in western Nicaragua, and evaluates their contributions to the development of the geothermal field models. Subsequent reservoir engineering has not been synthesized or evaluated. A geothermal exploration program was started in Nicaragua in 1966 to discover and delineate potential geothermal reservoirs in western Nicaragua. Exploration began at the Momotombo field in 1970 using geological, geochemical, and geophysical methods. A regional study of thermal manifestations was undertaken and the area on the southern flank of Volcan Momotombo was chosen for more detailed investigation. Subsequent exploration by various consultants produced a number of geotechnical reports on the geology, geophysics, and geochemistry of the field as well as describing production well drilling. Geological investigations at Momotombo included photogeology, field mapping, binocular microscope examination of cuttings, and drillhole correlations. Among the geophysical techniques used to investigate the field sub-structure were: Schlumberger and electromagnetic soundings, dipole mapping and audio-magnetotelluric surveys, gravity and magnetic measurements, frequency domain soundings, self-potential surveys, and subsurface temperature determinations. The geochemical program analyzed the thermal fluids of the surface and in the wells. This report presents the description and results of exploration methods used during the investigative stages of the Momotombo Geothermal Field. A conceptual model of the geothermal field was drawn from the information available at each exploration phase. The exploration methods have been evaluated with respect to their contributions to the understanding of the field and their utilization in planning further development. Our principal finding is that data developed at each stage were not sufficiently integrated to guide further work at the field, causing inefficient use of

    2014-01-01

    Reconstructing the formation and use of the hitherto neglected Pandechion epistemonicon, Ulisse Aldrovandi's (152-1605) extant manuscript encyclopaedia, this article shows that early modern naturalists in many ways shared a world of paper with the members of several other professions. An analysis of the Pandechion suggests that Renaissance naturalists who applied the humanist jack-of-all-trades, the commonplace book, in their own field sometimes considerably altered its form. Aldrovandi tested and recombined different techniques so as to arrive at the paper technology that he considered to be the most fit for his purposes. He thereby drew on administrative practices as well as on the bookkeeping practices of early modern merchants that he knew first-hand.

    Despite its considerable potential in household, domestic and industry sectors, the possible contribution of solar heat is often neglected in many academic and institutional energy projections and scenarios. This is best explained by the frequent failure to distinguish heat and work as two different forms of energy transfers. As a result, policy makers in many countries or States have tended to pay lesser attention to solar thermal technologies than to other renewable energy technologies.

    Full Text Available According to the new and previously known documents it is concluded the earthquake of Chile in 1730 was composed by two independent earthquakes, each associated to a tsunami. Considering the latitudinal extension of the damage and the size of the tsunamis, it can be taken as the largest seismic event occurred in the history of Metropolitan or Central Chile. These conclusions allow to know better the seismic sequence of Central Chile, the Seismic History of the country, and contribute to the knowledge of the colonial history of the kingdom of Chile.

    Asthma is the most common chronic childhood disease and has seen increasing prevalence worldwide. While there is existing evidence of familial and other risk factors for pediatric asthma, there is a need for further studies to explore and understand interactions among these risk factors. The goal of this study was to develop an approach for mining, visualizing, and evaluating association rules representing pairwise interactions among potential familial risk factors based on information documented as part of a patient's family history in the electronic health record. As a case study, 10,260 structured family history entries for a cohort of 1,531 pediatric asthma patients were extracted and analyzed to generate family history associations at different levels of granularity. The preliminary results highlight the potential of this approach for validating known knowledge and suggesting opportunities for further investigation that may contribute to improving prediction of asthma risk in children.

    1999-12-15

    Controversy persists about the etiology of Parkinson's disease (PD). Pesticides, herbicides, well-water consumption, head injury, and a family history of PD have been reported as risk factors for PD. The purpose of this study was to (1) investigate the impact of environmental factors on PD risk (2) estimate the chronology, frequency, and duration of those exposures associated with PD; and (3) investigate the effects of family history on PD risk. One-hundred and forty PD cases were recruited from Boston University Medical Center. The control group was composed of 147 friends and in-laws of PD patients. Environmental, medical, and family history data were obtained by structured interview from each participant for events recalled prior to PD onset for cases, or corresponding censoring age for controls (mean age = 56 years of age for each group). A traditional stratified analysis, adjusting for birth cohort and sex, was employed. Four factors were associated with increased risk for PD: (1) head injury (OR=6.23, confidence interval [CI]: 2.58-15.07); (2) family history of PD (OR=6.08, CI: 2.35-15. 58); (3) family history of tremor (OR=3.97, CI: 1.17-13.50); and (4) history of depression (OR=3.01, CI: 1.32-6.88). A mean latency of 36. 5 (SE=2.81) years passed between the age of first reported head injury and PD onset. A mean latency of 22 (SE=2.66) years passed between the onset of the first reported symptoms of depression and onset of PD. Years of education, smoking, and well-water intake were inversely associated with PD risk. PD was not associated with exposure to pesticides or herbicides. These findings support the role of both environmental and genetic factors in the etiology in PD. The results are consistent with a multifactorial model. Am. J. Med. Genet. (Neuropsychiatr. Genet.) 88:742-749, 1999.

    Full Text Available Abstract The major scientific advances of the last century featured the identification of the structure of DNA, the development of molecular biology and the technology to exploit these advances. These breakthroughs gave us new tools for crop improvement, including molecular marker-aided selection (MAS and genetic modification (GM. MAS improves the efficiency of breeding programs, and GM allows us to accomplish breeding objectives not possible through conventional breeding approaches. MAS is not controversial and is now routinely used in crop improvement programs. However, the international debate about the application of genetic manipulation to crop improvement has slowed the adoption of GM crops in developing as well as in European countries. Since GM crops were first introduced to global agriculture in 1996, Clive James has published annual reports on the global status of commercialized GM crops as well as special reports on individual GM crops for The International Service for the Acquisition of Agri-biotech Applications (ISAAA. His 34th report, Global Status of Commercialized Biotech/ GM crops: 2011 [1] is essential reading for those who are concerned about world food security.

  2. Cognitive theories as reinforcement history surrogates: the case of likelihood ratio models of human recognition memory.

    Science.gov (United States)

    Wixted, John T; Gaitan, Santino C

    2002-11-01

    B. F. Skinner (1977) once argued that cognitive theories are essentially surrogates for the organism's (usually unknown) reinforcement history. In this article, we argue that this notion applies rather directly to a class of likelihood ratio models of human recognition memory. The point is not that such models are fundamentally flawed or that they are not useful and should be abandoned. Instead, the point is that the role of reinforcement history in shaping memory decisions could help to explain what otherwise must be explained by assuming that subjects are inexplicably endowed with the relevant distributional information and computational abilities. To the degree that a role for an organism's reinforcement history is appreciated, the importance of animal memory research in understanding human memory comes into clearer focus. As Skinner was also fond of pointing out, it is only in the animal laboratory that an organism's history of reinforcement can be precisely controlled and its effects on behavior clearly understood.

    To examine the risk of thoracic aortic disease (TAD) when one or more first-degree relatives are affected, and to relate the risk of family history to the risk of other cardiopulmonary comorbidity. Population-based, matched, case-control study. Registry-based investigation. All cases, nationwide, of TAD diagnosed 2001-2005 in individuals born 1932 or later (n=2436) were identified, and a random control-group (n=12 152) matched for age, sex and geography was generated. First-degree relatives were identified in the Multigeneration Registry. Family history of TAD was assessed by cross-linking nationwide health registries. None. Family history was present in 108 cases (4.4%), compared with 93 (0.77%) controls (prisk of TAD increased with number of affected relatives: OR 5.8 (95% CI 4.3 to 7.7) vs OR 20 (2.2 to 179) with one versus two or more affected relatives. The relative risk of TAD was highest in the youngest (≤49 years) age group and slightly more pronounced in women than in men (OR 7.2 (4.2 to 12) vs OR 5.5 (3.9 to 7.7)). Among cardiopulmonary comorbidities, heart failure conferred the highest relative risk, OR 6.3 (4.1 to 9.8). Family history confers a significantly increased (sixfold to 20-fold) relative risk of TAD. The effect is more pronounced in women and in younger subjects, and is not conveyed by cardiopulmonary comorbidity. Knowledge of family history is important to counselling, treatment indications, surveillance and screening protocols.

    1999-01-01

    This paper reviews the experience of women workers in China while the country's economy is changing into a globalized, technologically advanced one. New computer-based technology is increasingly acknowledged as a powerful and pervasive force that can shape or, at least in many ways, affect employment. It is hailed for opening up fresh employment opportunities and reducing the physical stress involved in work. However, the possibilities of redundancies or intensification of workload also exist. By focusing on changes in women's work, the article reveals the contradictions inherent in following a development path based on ever-higher levels of technology in the context of an intensive mode of production, to which productivity is the core value. The economy is bolstered and some workers gain employment in expanding industries. However, workers, who lack access to training and who are reliant on the dwindling state support for their reproductive responsibilities, are marginalized and seek employment in the growing informal economy.

    Germany's energy supply status shows both an accumulation of unsatisfactory sustainabilities putting the nation's energy security at risk, and a hopeful sign: The nation's supply dependency on foreign sources and the accordingly unavoidable price dictate the nation suffers under is almost life risking; the technological skill, however, of the nation's researchers, engineers, and industry materializes in a good percentage of the indigenous and the world's energy conversion technology market. Exemplified with the up and coming hydrogen energy economy this paper tries to advocate the 21. century energy credo: energy policy is energy technology politics{exclamation_point} Energy source thinking and acting is 19. and 20. century, energy efficient conversion technology thinking and acting is 21. century. Hydrogen energy is on the verge of becoming the centre-field of world energy interest. Hydrogen energy is key for the de-carbonization and, thus, sustainabilization of fossil fuels, and as a storage and transport means for the introduction of so far un-operational huge renewable sources into the world energy market. - What is most important is hydrogen's thermodynamic ability to exergize the energy scheme: hydrogen makes more technical work (exergy) out of less primary energy{exclamation_point} Hydrogen adds value. Hydrogen energy and, in particular, hydrogen energy technologies, are to become part of Germany's national energy identity; accordingly, national energy policy as energy technology politics needs to grow in the nation's awareness as common sense{exclamation_point} Otherwise Germany seems ill-equipped energetically, and its well-being hangs in the balance.

    Full Text Available AbstractThe didactics of history and the content of the curriculum and syllabi have changed over the years in order to make history more relevant for the students of today. It is important to provide students with “knowing what” knowledge in addition to “knowing how” knowledge in order to support and develop critical thinking and historical understanding. One way of promoting historical understanding is through introducing the concepts of historical thinking. However, studies show that history classes often promote teaching that is still quite traditional, using history books uncritically and without problematizing their truthfulness, which do not make students see how history is formed, nor how it can be important for the present and the future. The present article explores whether the concepts of historical thinking are encouraged and used in three different lower secondary schools in Norway today. The main sources of data are current history textbooks, teaching plans, tests and assignments. The findings of the study show that the concepts of historical thinking are not made clear and explicit enough in neither history books, plans nor tests. Furthermore, it seems like reproduction rather than reflection is focused on in many classrooms, making it difficult to develop a historical understanding. It is therefore suggested that both teachers and students learn and work thoroughly with the concepts of historical thinking.schools in Norway today. History books in use, plans, tests and assignments were considered important empirical information for the research question. The findings of the study show that the concepts of historical thinking are not clear enough neither in history books, plans nor tests.

In operational terms, this translates into solutions that are as lifelike as possible and guarantee the maximum emotional involvement of the viewer, adopting the same techniques as are used in modern cinema. Communication thus becomes entertainment and a vehicle for high-quality content, aimed at the widest possible public and produced with the help of interdisciplinary tools and methods. In this context, high-end technologies are no longer the goal of research; rather they are the invisible engine of an unstoppable process that is making it harder and harder to distinguish between computer images and real objects. An emblematic case in this regard is the reconstructive study of ancient contexts, where three-dimensional graphics compensate for the limited expressive potential of two-dimensional drawings and allows for interpretative and representative solutions that were unimaginable a few years ago. The virtual space thus becomes an important opportunity for reflection and study, as well as constituting a revolutionary way to learn for the wider public.ItI risultati più significativi ottenuti dall’Information Technologies Lab (IBAM CNR - ITLab nella costruzione di piattaforme di conoscenza basate sulla Realtà Virtuale, sono stati conseguiti nell’ambito di progetti internazionali quali ByHeriNet, Archeotour, Interadria, Interreg Greece-Italy, Iraq Virtual Museum, ecc.

    Smart mobile and wearable technology offers exciting opportunities to support people with dementia (PwD). Its ubiquity and popularity could even benefit user adoption - a great challenge for assistive technology (AT) for PwD that calls for user-centred design (UCD) methods. This study describes a user-centred approach to developing and testing AT based on off-the-shelf pervasive technologies. A prototype is created by combining a smartphone, smartwatch and various applications to offer six support features. This is tested among five end-users (PwD) and their caregivers. Controlled usability testing was followed by field testing in a real-world context. Data is gathered from video recordings, interaction logs, system usability scale questionnaires, logbooks, application usage logs and interviews structured on the unified theory of acceptance and use of technology model. The data is analysed to evaluate usability, usefulness and user acceptance. Results show some promise for user adoption, but highlight challenges to be overcome, emphasising personalisation and familiarity as key considerations. The complete findings regarding usability issues, usefulness of support features and four identified adoption profiles are used to provide a set of recommendations for practitioners and further research. These contribute toward UCD practices for improved smart, pervasive AT for dementia.

    A case-control study design was used to investigate risks of work-related physical assault (PA) associated with a history of violent victimization among educators. A total of 6,469 state-licensed educators (Kindergarten - Grade 12) worked in the previous 12~months and were eligible to participate. Exposure data were collected from cases (reporting a PA event in previous 12 months, n=290) for the month before PA, and from controls (no work-related PA in previous 12 months; n=867) for a randomly selected working month. Odds ratios and 95% confidence intervals identified increased risks for educators with any prior history of work-related (17.3, 11.4-26.3) or non-work-related PA (2.0, 1.2-3.5). In addition, PA risk in the previous twelve months increased with the number of previous victimizations, and risk also increased for educators with histories of non-physical violence (work- and non work-related). The results present a compelling case for targeted interventions and further research.

This paper is an attempt to explore the role of strategic planning in the high tech industry using a specific case of aerospace industry in Indonesia.  In order to compete effectively inthe open global marketplace, the company must learn to integrate technology managementwith strategic planning. In other words, all top managers have to linktheir technology capabilities to marketing requirements.Keywords:  technology planning; business strategy; technology capability; marketing requirement; strategic mix

    2006-08-01

    Full Text Available Abstract Background Orlistat is an anti-obesity drug licensed in the United Kingdom for 7 years. We present a case of a patient who developed pancreatitis four days after commencing orlistat. Case presentation A 36 year old man presented to hospital with acute severe pancreatitis four days after starting a course of Orlistat, a lipase inhibitor used in the treatment of obesity. A diagnosis of drug related pancreatitis was made by exclusion of other causes of pancreatitis; he was a teetotaller, had a normal serum calcium, had no family history of pancreatitis or hyperlipidaemia, no history of trauma and had no evidence of gallstones on Computerised Tomography scan (CT. Conclusion Orlistat was the only drug that had been started recently and has been associated with pancreatitis previously. We found no case reports of similar cases, however 99 cases of orlistat related pancreatitis have been reported to the Food and Drug Administration (FDA, but no causative link has been found in clinical trials by the drug company. It is therefore not on the list of possible complications or side effects of the drug.

  2. Private Information Disclosure from Web Searches. (The case of Google Web History)

    CERN Document Server

    Castelluccia, Claude; Perito, Daniele

    2010-01-01

    As the amount of personal information stored at remote service providers increases, so does the danger of data theft. When connections to remote services are made in the clear and authenticated sessions are kept using HTTP cookies, data theft becomes extremely easy to achieve. In this paper, we study the architecture of the world's largest service provider, i.e., Google. First, with the exception of a few services that can only be accessed over HTTPS (e.g., Gmail), we find that many Google services are still vulnerable to simple session hijacking. Next, we present the Historiographer, a novel attack that reconstructs the web search history of Google users, i.e., Google's Web History, even though such a service is supposedly protected from session hijacking by a stricter access control policy. The Historiographer uses a reconstruction technique inferring search history from the personalized suggestions fed by the Google search engine. We validate our technique through experiments conducted over real network tr...

  3. History effects in the sedimentation of light aerosols in turbulence: the case of marine snow

    CERN Document Server

    Guseva, Ksenia; Feudel, Ulrike; Tél, Tamás

    2016-01-01

    We analyze the effect of the Basset history force on the sedimentation of nearly neutrally buoyant particles, exemplified by marine snow, in a three-dimensional turbulent flow. Particles are characterized by Stokes numbers much smaller than unity, and still water settling velocities, measured in units of the Kolmogorov velocity, of order one. The presence of the history force in the Maxey-Riley equation leads to individual trajectories which differ strongly from the dynamics of both inertial particles without this force, and ideal settling tracers. When considering, however, a large ensemble of particles, the statistical properties of all three dynamics become more similar. The main effect of the history force is a rather slow, power-law type convergence to an asymptotic settling velocity of the center of mass, which is found numerically to be the settling velocity in still fluid. The spatial extension of the ensemble grows diffusively after an initial ballistic growth lasting up to ca. one large eddy turnove...

  4. Enhancing international technology cooperation for climate change mitigation. Lessons from an electromobility case study

    Energy Technology Data Exchange (ETDEWEB)

    Bhasin, Shikha

    2014-07-01

    As a global agreement on climate mitigation and absolute emissions reductions remains grid-locked, this paper assesses whether the prospects for international technology cooperation in low-carbon sectors can be improved. It analyses the case of international cooperation on electric vehicle technologies to elaborate on the trade-offs that cooperation such as this inherently attempts to balance- national growth objectives of industrial and technology development versus the global goods benefit of reducing greenhouse gas (GHG) emissions. It focuses on bilateral German-Chinese programmes for electric vehicle development, as well as multilateral platforms on low-carbon technology cooperation related to electric vehicles. Based on insights from these cases studies, this paper ultimately provides policy recommendations to address gaps in international technology cooperation at a bilateral level for ongoing German-Chinese engagement on electric vehicles; and at a multilateral level with a focus on the emerging technology cooperation framework of the United Nations Framework Convention on Climate Change (UNFCCC).

    2014-01-01

    科学技术史是大学通识教育常设课程之一,在课程安排上,包括科学史、技术史和STS,然而其学科归属却是科学史。这种课程内容和学科归属的不对称源于“科学”概念之内涵的扩展,从古代科学的哲学家传统和工匠传统,到近代科学的哲学家传统定义,再到二战后大科学时代的来临,科学内涵从与技术分离转变为和技术合体,最后变为同一个概念“科学技术”,而整个转变和发展的过程总是依循科学的历史发展和其社会建制形式的转变,故科学技术史是广义的科学史。%History of science and technology is one of the perma-nent general education courses at university, and the course in-cludes history of science, history of technology and STS, however, it belongs to history of science. This asymmetry between curricu-lum content and discipline category originates from the connota-tion expansion of "science". From the philosopher tradition and artisan tradition of ancient science, to the traditional definition of philosophers in modern science, and then to the advent of big science era after the World War II, the connotation of science transformed from the separation from technology to the integration with technology, and finally become the same concept, "science and technology", but the whole transformation and development process always follows the historical development of science and the change of the form of social institutions, so history of science and technology is a broad history of science.

    Vogt, Marjorie A; Schaffner, Barbara H

    2016-07-01

    Nursing education is challenged to prepare students for complex healthcare needs through the integration of teamwork and informatics. Technology has become an important teaching tool in the blended classroom to enhance group based learning experiences. Faculty evaluation of classroom technologies is imperative prior to adoption. Few studies have directly compared various technologies and their impact on student satisfaction and learning. The purpose of this study was to evaluate technology enhanced teaching methods on the learning and satisfaction of graduate students in an advanced pharmacology class using an unfolding case study. After IRB approval, students were randomly assigned to one of three groups: blogging group, wiki group or webinar group. Students completed the evolving case study using the assigned interactive technology. Student names were removed from the case studies. Faculty evaluated the case study using a rubric, while blinded to the assigned technology method used. No significant difference was found on case study grades, the range of grades on the assignment demonstrated little differences between the methods used. Students indicated an overall positive impact related to networking and collaboration on a satisfaction survey. Impact of technology methods needs to be explored in other areas of graduate nursing education.

    2016-11-01

    We analyze the effect of the Basset history force on the sedimentation of nearly neutrally buoyant particles, exemplified by marine snow, in a three-dimensional turbulent flow. Particles are characterized by Stokes numbers much smaller than unity, and still water settling velocities, measured in units of the Kolmogorov velocity, of order one. The presence of the history force in the Maxey-Riley equation leads to individual trajectories which differ strongly from the dynamics of both inertial particles without this force and ideal settling tracers. The main effect of the history force is an extraordinary slow, power-law type convergence to an asymptotic settling velocity of the center of mass, which is found numerically to be the settling velocity in still fluid. The spatial extension of the ensemble grows diffusively after an initial ballistic growth lasting up to circa one large eddy turnover time. We demonstrate that the settling of the center of mass for such light aggregates is best approximated by the settling dynamics in still fluid found with the history force, on top of which fluctuations appear which follow very closely those of the turbulent velocity field.

  11. Technology commercialization cost model and component case study

    Science.gov (United States)

    1991-12-01

    Fuel cells seem poised to emerge as a clean, efficient, and cost competitive source of fossil fuel based electric power and thermal energy. Sponsors of fuel cell technology development need to determine the validity and the attractiveness of a technology to the market in terms of meeting requirements and providing value which exceeds the total cost of ownership. Sponsors of fuel cell development have addressed this issue by requiring the developers to prepare projections of the future production cost of their fuel cells in commercial quantities. These projected costs, together with performance and life projections, provide a preliminary measure of the total value and cost of the product to the customer. Booz-Allen & Hamilton Inc. and Michael A. Cobb & Company have been retained in several assignments over the years to audit these cost projections. The audits have gone well beyond a simple review of the numbers. They have probed the underlying technical and financial assumptions, the sources of data on material and equipment costs, and explored issues such as the realistic manufacturing yields which can be expected in various processes. Based on the experience gained from these audits, DOE gave Booz-Allen and Michael A. Cobb & company the task to develop a criteria to be used in the execution of future fuel cell manufacturing cost studies. It was thought that such a criteria would make it easier to execute such studies in the future as well as to cause such studies to be more understandable and comparable.

    Full Text Available Intrastromal corneal ring segments (INTACS implantation for mild myopia or keratoconus is simple and effective in most cases. Rarely, major complications can occur due to implantation. In this case report, we present two examples of possible intraoperative and postoperative complications of INTACS. The first case had histopathologic documentation of Descemet′s membrane perforation as an intraoperative complication and the second case had accumulation of foamy histiocytes along the lamellar channels which has not been previously reported. These complications suggest further study is required on the long term effect of INTACS implantation on corneal tissue.

  20. REGIONAL DEVELOPMENT AS A CHAIN PROCESS OF ORGANIZATIONAL DYNAMICS AND TECHNOLOGICAL ROUTES: THE CASE OF SANTA CATARINA'S WESTERN REGION

    Directory of Open Access Journals (Sweden)

    Bianca Cristina Aléssio

    2014-12-01

    Full Text Available The last decades witnessed a transformation of the concept of development and of the analysis of its explanatory variables. Regional/local specificities became important aspects of development processes since each territory reacts differently to different strategies and creates specific solutions for its development. This article analyzes the path of a regional development process from the perspective of the institutional, schumpeterian and territorial approach theories. They provide important references to analyze development processes at the local level, as they consider history, culture, behavior codes, values and techniques as determinants of development. The study builds on Santa Catarina's Western region case and shows that regional development processes can be analyzed with the support of these theories as a chain of organizational dynamics and local technological trajectories that influence each other and determine the possible courses of territorial development.

    Kiendrébéogo, D; Kambiré, R; Jamonneau, V; Lingué, K; Solano, P; Courtin, F

    2012-11-01

    In the first half of the XXth century, while Upper-Volta (now Burkina Faso) was suffering a terrible epidemic of sleeping sickness, the French colonial administration encouraged the movement of people from Upper-Volta to Ivory Coast to meet their demands for labour. This led to the establishment of Mossi villages, such as those of Koudougou, in the Ivorian forest with populations originating from areas of Upper-Volta that were not only densely populated but also severely affected by sleeping sickness. Since 2000, most cases of sleeping sickness in the Koudougou district of Burkina Faso have been in people originally from Ivory Coast. Who are they? Where did they settle in Burkina Faso? Where do they come from in Ivory Coast? After having retraced the epidemiological history of Koudougou villages in Burkina Faso and Ivory Coast, the history of ten cases of sleeping sickness detected passively at Koudougou hospital since 2000 were analysed. All cases originated from the forest area of Ivory Coast. Understanding the spread of sleeping sickness between Burkina Faso and Ivory Coast will assist in the identification of areas of disease risk.

  2. The role of initial coherence and path materials in the dynamics of three rock avalanche case histories

    Aaron, Jordan; McDougall, Scott; Moore, Jeffrey R.; Coe, Jeffrey A.; Hungr, Oldrich

    2017-01-01

    BackgroundRock avalanches are flow-like landslides that can travel at extremely rapid velocities and impact surprisingly large areas. The mechanisms that lead to the unexpected mobility of these flows are unknown and debated. Mechanisms proposed in the literature can be broadly classified into those that rely on intrinsic characteristics of the rock avalanche material, and those that rely on extrinsic factors such as path material. In this work a calibration-based numerical model is used to back-analyze three rock avalanche case histories. The results of these back-analyses are then used to infer factors that govern rock avalanche motionResultsOur study has revealed two key insights that must be considered when analyzing rock avalanches. Results from two of the case histories demonstrate the importance of accounting for the initially coherent phase of rock avalanche motion. Additionally, the back-analyzed basal resistance parameters, as well as the best-fit rheology, are different for each case history. This suggests that the governing mechanisms controlling rock avalanche motion are unlikely to be intrinsic. The back-analyzed strength parameters correspond well to those that would be expected by considering the path material that the rock avalanches overran.ConclusionOur results show that accurate simulation of rock avalanche motion must account for the initially coherent phase of movement, and that the mechanisms governing rock avalanche motion are unlikely to be intrinsic to the failed material. Interaction of rock avalanche debris with path materials is the likely mechanism that governs the motion of many rock avalanches.

    2015-09-01

    Full Text Available Background Several factors have been reported as risk factors for multiple sclerosis (MS; however, the main causes of the disease are still unknown. A geographical area with a low MS incidence is Ahvaz, Iran. Objectives The objective of this study was to evaluate the association of several demographic characteristics, family history, and birth month with MS in Ahvaz. Patients and Methods This was a case-control study including 155 MS cases and 155 controls matched for age, sex, and residential status. The participants were selected randomly, using a systematic method, from the MS patients referred to the MS Society of Khuzestan (Iran. The data collection tool was a standardized questionnaire designed by the authors to assess demographic characteristics. Data were analyzed using descriptive statistics including mean, frequency, and standard deviation and inferential statistical tests including χ2, Fisher’s exact test, and logistic regression using SPSS version 19. Results In both cases and controls, no significant associations were found between Arab ethnicity and incidence of MS, marital status and risk of MS in Ahvaz, or more than 15-year residency in Ahvaz, birth in Khuzestan, and month of birth and the risk of MS (P > 0.05. However, there was a marginally significant association between living from birth to age 15 years in Ahvaz and MS (P = 0.05. Furthermore, there was an association between a family history of MS and the risk of MS in Ahvaz (P = 0.02, which was significant in univariate logistic regression (P = 0.006. Conclusions The findings suggested that according to the ecological conditions of Ahvaz, a family history of MS may increase the risk of developing MS.

    2014-12-01

    Full Text Available Polytechnic instruction has a common place in the Cuban education system (Gasperini, 2000. In polytechnic institutions, teachers leverage technological tools to prepare students for labor market competences. This case study examined a polytechnic institution in Cuba to consider how teachers defined educational technology. Based on teacher questionnaire responses, site-based teacher interviews, and field observations, technology was primarily viewed as a method for student preparation. In other words, teachers used technology to prepare students for their future careers and the technology they will need to be successful in that career. The study found that teachers highly valued their technical pedagogical training, believed that the growing spaces were an integral part of their technology based instruction, and claimed that the limited resources was their greatest barrier to integrating ICT in the classroom.

  7. The quality case for information technology in healthcare

    Directory of Open Access Journals (Sweden)

    Bates David W

    2002-10-01

    Full Text Available Abstract Background As described in the Institute of Medicine's Crossing the Quality Chasm report, the quality of health care in the U.S. today leaves much to be desired. Discussion One major opportunity for improving quality relates to increasing the use of information technology, or IT. Health care organizations currently invest less in IT than in any other information-intensive industry, and not surprisingly current systems are relatively primitive, compared with industries such as banking or aviation. Nonetheless, a number of organizations have demonstrated that quality can be substantially improved in a variety of ways if IT use is increased in ways that improve care. Specifically, computerization of processes that are error-prone and computerized decision support may substantially improve both efficiency and quality, as well as dramatically facilitate quality measurement. This report discusses the current levels of IT and quality in health care, how quality improvement and management are currently done, the evidence that more IT might be helpful, a vision of the future, and the barriers to getting there. Summary This report suggests that there are five key policy domains that need to be addressed: standards, incentives, security and confidentiality, professional involvement, and research, with financial incentives representing the single most important lever.

    2015-01-01

    Epidermolysis bullosa (EB) is a rare skin disorder characterized by blister formation in response to minor trauma and accompanied by extracutaneous manifestations. The use of endosseous implants to support fixed prostheses for the rehabilitation of patients with recessive dystrophic EB might provide a considerably better clinical treatment outcome than traditional prosthodontic interventions. This case history report describes the clinical management of such an afflicted patient. Implants were placed immediately following teeth extractions and subsequently loaded with fixed full-arch prostheses. This treatment option is proposed for patients with recessive dystrophic EB to preclude mucosal irritation associated with wearing removable prostheses.

  10. Functional gene polymorphism to reveal species history: the case of the CRTISO gene in cultivated carrots.

    Directory of Open Access Journals (Sweden)

    Vanessa Soufflet-Freslon

    Full Text Available BACKGROUND: Carrot is a vegetable cultivated worldwide for the consumption of its root. Historical data indicate that root colour has been differentially selected over time and according to geographical areas. Root pigmentation depends on the relative proportion of different carotenoids for the white, yellow, orange and red types but only internally for the purple one. The genetic control for root carotenoid content might be partially associated with carotenoid biosynthetic genes. Carotenoid isomerase (CRTISO has emerged as a regulatory step in the carotenoid biosynthesis pathway and could be a good candidate to show how a metabolic pathway gene reflects a species genetic history. METHODOLOGY/PRINCIPAL FINDINGS: In this study, the nucleotide polymorphism and the linkage disequilibrium among the complete CRTISO sequence, and the deviation from neutral expectation were analysed by considering population subdivision revealed with 17 microsatellite markers. A sample of 39 accessions, which represented different geographical origins and root colours, was used. Cultivated carrot was divided into two genetic groups: one from Middle East and Asia (Eastern group, and another one mainly from Europe (Western group. The Western and Eastern genetic groups were suggested to be differentially affected by selection: a signature of balancing selection was detected within the first group whereas the second one showed no selection. A focus on orange-rooted carrots revealed that cultivars cultivated in Asia were mainly assigned to the Western group but showed CRTISO haplotypes common to Eastern carrots. CONCLUSION: The carotenoid pathway CRTISO gene data proved to be complementary to neutral markers in order to bring critical insight in the cultivated carrot history. We confirmed the occurrence of two migration events since domestication. Our results showed a European background in material from Japan and Central Asia. While confirming the introduction of European

    Patients with severe acute and chronic lower extremity wounds often present a significant challenge in terms of limb salvage. In addition to control of infection, assuring adequate perfusion and providing standard wound care, advanced modalities are often required to facilitate final wound closure. We herein present a case study on a diabetic patient with gangrene and necrotising soft-tissue infection who underwent a forefoot pedal amputation to control the sepsis. Despite his non invasive vascular studies demonstrating poor healing potential at this level, he was not deemed suitable for revascularisation by our vascular surgeons and ankle-level amputation was recommended. Nonetheless, over a 5-month period using multiple advanced wound care therapies, wound closure was ultimately achieved.

    Yasnitsky, Anton; Ferrari, Michel

    2008-05-01

    Between the death of Vygotsky in 1934 and the discovery of Vygotsky's work in the West in 1962, Vygotskian psychology was developed through research done by the first generation of Vygotsky's students and their followers, primarily associated with the Kharkov School. Surprisingly, these studies carried out in the 1930s, of great importance for the development of virtually all subsequent Vygotskian psychology, still remain largely unknown; this represents a significant gap in understanding the history of Vygotskian psychology as an empirical study of consciousness. This paper provides a systematic overview of the research agenda of the Kharkov group between 1931 and 1941 and provides new insights into the early development of Vygotskian psychology.

    2014-01-01

    Objective Maternal folate supplementation reduces offspring risk for neural tube defects (NTDs) and other congenital abnormalities. Maternal red blood cell (RBC) folate concentrations of >906nmol/L have been associated with the lowest risk of having an NTD affected pregnancy. Mood disorders (e.g. depression, bipolar disorder) are common among women and can be associated with folate deficiency. Thus, pregnant women with histories of mood disorders may be prone to RBC folate levels insufficient to provide optimal protection against NTDs. While previous studies have assessed RBC folate concentrations in pregnant women from the general population, none have looked specifically at a group of pregnant women who have a history of a mood disorder. Methods We collected data about RBC folate concentrations and folic acid supplement intake during early pregnancy (906nmol/L, despite all participants reporting current daily use of folic acid supplements. Data regarding offspring were available for 22 women: birthweights ranged from 2296g to 4819g, and congenital abnormalities were identified in two (hypoplastic left heart, annular pancreas). Conclusion Data from this exploratory case series suggest a need for future larger scale controlled studies investigating RBC folate concentrations in early pregnancy and offspring outcomes among women with and without histories of mood disorders.

    Full Text Available The paper presents the initial part of a study designed to understand the place of the present generation of engineering students in the global picture of their working life. The education represents an inestimable good that accompanies peoples through their existence. Higher education is the place were teenagers with different profiles modelled by their families, studies; experiences and so on come to meet, in most cases, the final education platform before employment. In light of this the higher education has the major role of prepare the students with the knowledge and skills appropriate to the labour market. That means with the knowledge and skills they need and their future employers are looking for. It involves a huge effort, dedicated to the transfer of knowledge and skills with a success rate as high as possible. To achieve this the study programs and the teaching methods must embody both objectives: to be tailored for the students and to meet the employers needs. That places the higher education on the border of the two parties, its role in achieving the outlined objectives being major.

  17. The Legitimation of Novel Technologies: The Case of Nanotechnology

    Science.gov (United States)

    Thyroff, Anastasia E.

    Nanotechnology is the control, manipulation, and application of matter on an atomic and molecular level. The technology is complex and confusing to consumers, and its long-term safety and effect on the human body, as well as the environment, are unknown. However, for the past decade, nanotechnology has been used to develop consumer products and food with novel and attractive attributes. Since nanotechnology is still not well known, it is not legitimized; that is, it has not been deemed safe and accepted by society. However, the market for nanotechnology is in the legitimation process. It will take an entire network of key stakeholders playing a specific roles for nanotechnology to legitimize. Specifically, each key stakeholder will align with a certain cultural discourse to frame nanotechnology in a particular way that complements their values. In Essay 1, I follow previous market system dynamic's literature and combine Actor Network Theory (ANT), Foucault's Discourse on Power and Goffman's Frame analysis to theoretically explore what the actor network for nanotechnology looks like. Four dominate frames are identified: 1) Advancement (i.e., government), 2) Management (i.e., industry), 3) Development (i.e., academia/scientists), and 4) Informant (i.e., NGO). Essay 2 empirically explores each actor's perspective on the nanotechnology network through a total of 24 interviews. A hermeneutic approach is used to analyze the 208 page text and themes describing each actor's role from a self and other's perspective are discussed. Additionally, three overarching themes (i.e., contradiction, constance, and cutoff) emerge; these themes describe the degree of similarity in how actors view their role in the nanotechnology network compared to how other actor's view that actor's role. In Essay 3, I bring critical theory into market system's research to better contextualize market formation theories. Specifically, I discuss how critical theory can be used to supplement ANT. I

    Symptomatic epigastric hernia is rare in pregnant women. A case history, management of which prompted a systematic review of the literature and proposed plan for treatment of such cases, is hereby presented. There is paucity of information on management of this condition in the standard literature as searches in Pubmed, Science Direct, Hinari, Medline, African Journal Online, Bioone as well as Cochrane library revealed. There are two schools of thought for the management of hernias in pregnancy-watchful waiting and herniorrhaphy in pregnancy. There is no consensus or definite guideline on the management of epigastric hernias in pregnancy. Based on the literature review, a management algorithm is proposed, which combines the two schools of thought.

    2012-02-01

    A Child Analysis with Anna Freud, a collection of Anna Freud's detailed case notes of her treatment of the young Peter Heller between 1929 and 1932, was first published in English in 1990. Not only does this work give us direct access to Anna Freud's ways of thinking and working at a crucial period in the early history of child analysis; it is also one of the few records of an adult reflecting in depth on the experience of being in analysis as a child. Yet to date this work has received little attention in the psychoanalytic literature. In an attempt to redress this neglect, the Heller case study is placed in the context of Anna Freud's emerging ideas about child analysis. In particular, its significance in the development of her psychoanalytic thinking is investigated in the light of her 1927 book, The Technique of Child Analysis.

  20. Technology installation review. A case study on energy-efficient technologies

    2001-12-31

    The purpose of this Technology Installation Review is to provide an overview of hybrid geothermal heat pump systems. It presents the results of recent research on these systems, looks at system types, energy savings, maintenance considerations, and measured technology performance from several examples. Using the ground as a thermal energy source and/or a heat sink for heat pumps has long been recognized to have a number of advantages over the similar use of ambient air. Ground temperatures at about 3-ft depth or lower are much less variable than ambient air temperatures. Further, soil or rock at these depths is usually warmer than ambient air during the coldest winter months and cooler than ambient air during the summer months. This fact leads directly to cooler condensation temperatures (during cooling operation) and warmer evaporating temperatures (during heating) for a heat pump with consequent improved energy efficiency. It also results in increased heating and cooling capacity at extreme temperatures, thereby reducing or eliminating the need for auxiliary heat.

  1. Accumulation of technological capabilities and operational performance improvement: evidence from a firm-level case study

    Marcelio Fonseca

    2014-11-01

    Full Text Available Drawing on a single case study based on first-hand and long-term evidence gathered through extensive fieldwork, this article examines the process of technological capability accumulation and its implications for operational performance improvement in a chemical firm in Brazil (1980-2007. The evidence indicates that the efforts on technological capability accumulation, especially for innovative activities, permitted the case-study firm to improve its operational performance, notably in terms of technical and, to some extent, in terms of commercial indicators. This study contributes to advancing our understanding of relationship between the firm-level accumulation of technological capabilities and operational performance improvement. The study draws managers’ attention to the importance of managing and measuring a multiplicity of technological capabilities within firms and to the relevance of firm-level engineering-based innovative activities, normally neglected by policy makers.

    2010-12-01

    Full Text Available Abstract Introduction The Z-drugs, zaleplon, zopiclone and zolpidem, are short-acting hypnotics which act at the same receptor as the benzodiazepines, but seemingly without the potential for misuse and the development of dependence of the older benzodiazepines. However, with increased prescribing of Z-drugs, reports of misuse and possible dependence began to appear in the literature, particularly in people with a history of substance misuse and comorbid psychiatric illness. Here we report the case of a woman with a history of chronic zopiclone use and anorexia nervosa, admitted for alcohol detoxification. Case presentation A 31-year old Caucasian British woman with a history of long-term zopiclone use and anorexia nervosa was admitted as an inpatient for a ten-day alcohol detoxification. Her weekly (four days out of seven intake of alcohol was 180 units and her daily intake of zopiclone, 30 mg. Apart from a short period five years ago, she had been taking zopiclone for 13 years at daily doses of up to 90 mg. She admitted to using 'on top' of her prescribed medication, purchasing extra tablets from friends or receiving them gratis from her partner. After detoxification from alcohol and zopiclone, she was prescribed diazepam which she found ineffectual and voiced her intention of returning to zopiclone on leaving the hospital. Conclusion Zopiclone is generally regarded as safer than benzodiazepines, however, this particular individual, who was using high doses of zopiclone over many years, may provide further evidence of a risk of dependency when this drug is prescribed for substance users with a comorbid psychiatric illness.

  4. The Infertile Crescent Revisited: A Case (Study for the History of Archaeology

    Jennifer Bracewell

    2015-05-01

    Full Text Available This paper examines the history of archaeological research concerning the eastern coast of James Bay in northern Quebec. The construction of prehistory in northern Quebec began with the earliest contact of Europeans with Native Canadians and developed from religious explanations to Classical Evolutionary ones to Culture-Historical ones to Neoevolutionary scientific ones. Although the theoretical interpretations changed over time, the content remained surprisingly constant. The challenges of research in the area, and the resulting paucity of data, led to generalizations that telescoped thousands of years and eight million square miles into a single interpretation, based largely on eighteenth- and nineteenth-century assumptions about hunter-gatherer mobility, subsistence and social evolution. This paper traces how these assumptions have affected the archaeology of the twentieth century in James Bay and northern Quebec.

    Anderson, Heather; Kowal, Emma

    2012-01-01

    The poor health of Indigenous Australians is well established. However, the health of residents of one remote community in the Northern Territory of Australia called Utopia has been found recently to be much better than expected. In this article, we draw on historical anthropological research to explain this finding. We trace how cultural and social structures were maintained through changing eras of government policy from the 1930s, and show how these structures strengthened psychosocial determinants of health. We argue that the mainstream psychosocial determinants of social cohesion and self-efficacy are usefully reconceptualized in an Indigenous context as connectedness to culture and land, and collective efficacy, respectively. Continuity of cultural and social structures into the 1940s was facilitated by a combination of factors including the relatively late colonial occupation, the intercultural practices typical of the pastoral industry, the absence of a mission or government settlement, and the individual personalities and histories of those connected to Utopia.

    Since 1982 when secondary. poisoning of Red-tailed Hawks (Buteo jamaicensis) was documented following the recommended use of famphur on cattle, the Patuxent Wildlife Research Center has tested for organophosphate (OP) poisoning in selected birds of prey found dead. This report documents the circumstances for a number of. cases where birds of prey were killed by OP pesticides in the United States. Many of the cases were brought to our attention by the U S. Fish and Wildlife Service Division of Law Enforcement The cases may be divided into three categories: misuse, approved use, and unknown. Now that we are looking for OP poisoning of birds of prey, we are finding it more frequently than previously suspected.

    2008-07-01

    The global context of unequal development chances is reflected both by the differing availability of food energy and by imbalances in technically generated energy. The transformation of food into fuels could well aggravate these global disparities still further. It has to date only been possible to satisfy the hunger of the industrial nations for automobility with fuels won by synthetic methods. The paper approaches the history of energetic inequalities in a critical discussion with food and mobility paradigms. A focus is placed on different dimensions of technologically induced inequalities: These include the unequal distribution of power, the social limitations on participation chances and gender-specific technology appropriations.

  14. Providing Appropriate Technology for Emerging Markets: Case Study on China’s Solar Thermal Industry

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Building on a case study of five Chinese solar thermal companies and one association, our study aims to understand how the innovator’s choices regarding the use of technology and organizational practices for new product development enable companies to design and diffuse appropriate technology in emerging markets. The study uncovers two critical factors that enhance the appropriateness of technology: redefining the identity of technology and building a local supply system. Our analysis shows that synergic innovation in both architecture and component leads to the appropriate functionalities desired by emerging markets. Moreover, modular design and the building of a local supply system enhance the process appropriateness of technology. Our study provides an empirical basis for advocating going beyond minor adaptations of existing products to creating appropriate technology for emerging markets, and extends our understandings of the upstream process of designing appropriate technology. Moreover, the emphasis on the local supply system reflects a holistic framework for shaping and delivering appropriate technology, expanding the existing research focus on the perspective of the technology itself. Our research also has managerial implications that may help firms tap into emerging markets.

  15. Supporting Problem Solving with Case-Stories Learning Scenario and Video-based Collaborative Learning Technology

    2004-04-01

    Full Text Available In this paper, we suggest that case-based resources, which are used for assisting cognition during problem solving, can be structured around the work of narratives in social cultural psychology. Theories and other research methods have proposed structures within narratives and stories which may be useful to the design of case-based resources. Moreover, embedded within cases are stories which are contextually rich, supporting the epistemological groundings of situated cognition. Therefore the purposes of this paper are to discuss possible frameworks of case-stories; derive design principles as to “what” constitutes a good case story or narrative; and suggest how technology can support story-based learning. We adopt video-based Computer-Supported Collaborative Learning (CSCL technology to support problem solving with case-stories learning scenarios. Our hypothesis in this paper is that well-designed case-based resources are able to aid in the cognitive processes undergirding problem solving and meaning making. We also suggest the use of an emerging video-based collaborative learning technology to support such an instructional strategy.

    2012-01-01

    Leveraging diversity to successfully influence business operations is a business imperative for many healthcare organizations as they look to leadership to help manage a new era of culturally competent, patient-centered care that reduces health and healthcare disparities. This article presents the foundation for a business case in leadership diversity within healthcare organizations and describes the need for research on managerial solutions to health and healthcare disparities. It provides a discussion of clinical, policy, and management implications that will help support a business case for improving the diversity of leadership in healthcare organizations as a way to reduce health and healthcare disparities. Historical contexts introduce aspects of the business case for leveraging leadership diversity based on a desire for a culturally competent care organization. Little research exists on the impact that the role of leadership plays in addressing health disparities from a healthcare management perspective. This article provides practitioners and researchers with a rationale to invest in leadership diversity. It discusses three strategies that will help set the stage for a business case. First, provide empirical evidence of the link between diversity and performance. Second, link investments in diversity to financial outcomes and organizational metrics of success. Third, make organizational leadership responsible for cultural competence as a performance measure. In order to address health and healthcare disparities, collaborations between researchers and practitioners are necessary to effectively implement these strategies.

    Directory of Open Access Journals (Sweden)

    Lorenzana Claudia

    2011-10-01

    Full Text Available Abstract Introduction Cardiac tamponade is a rare manifestation of hypothyroidism, and a less rare cause of pericardial effusion. The accumulation of the pericardial fluid is gradual, and often does not compromise cardiac hemodynamic function. There is a relationship between the severity and chronicity of the disease with the presence of pericardial effusion. There are few cases describing associated pericardial tamponade published in the literature. When a tamponade occurs, a concomitant provocative factor such as a viral pericarditis may be related. Our patient's case appears to be the youngest patient described so far. Case presentation We report the case of a previously healthy five-year-old Hispanic (non-indigenous boy who developed rhabdomyolysis with a history of a recent pericardial effusion and tamponade two months before that required the placement of a percutaneous pericardial drainage. Pericardial effusion was considered to be viral. Later on readmission, clinical primary hypothyroidism was diagnosed and thought to be associated with the previous cardiac tamponade. He developed rhabdomyolysis, which was considered to be autoimmune and was treated with steroids. The level of creatine phosphate kinase and creatine kinase MB fraction returned to within the reference rangeone week after our patient was started on steroids and three weeks after he was started on thyroid hormones. Conclusions Physicians should consider hypothyroidism as a differential diagnosis in patients with pericardial effusion. Pericardial effusion may progress and cause a cardiac tamponade with hemodynamic instability. The fact that our patient did not have any manifestations of hypothyroidism might have delayed diagnosis.

    Coulter, S.; Waugh, G. [Talisman Energy Inc., Calgary, AB (Canada)

    2002-07-01

    The development of the Goldsmith/Lakeshore oil and gas field located in Mersea and Romney Townships in southwestern Ontario was described with reference to the geological, geophysical and engineering aspects of the field. It was discovered in 1985 and has since produced 5 MMSTB oil and 3 Bcf gas from the Middle Ordovician carbonates of the Trenton Group. A total of 40 wells currently produce about 700 bopd and 1 MMcfg/d. The field is expected to continue to make a significant contribution to Ontario's total oil production for many years. The remaining reserves are estimated at 2 MMSTB oil and 1 Bcf gas. The development history over the 17 year period can be sub-divided into 4 distinct phases: (1) the early years from 1985-1989, (2), the development phase from 1990-1993, (3) the mature phase from 1994-1997, and (4) the horizontal drilling phase from 1998-2002. This paper describes the heterogeneous nature of the reservoir and the changes in drilling and completion practices over the years. In particular, it describes in detail how Talisman Energy Ltd. used horizontal drilling to develop an extension of the field beneath Lake Erie. Talisman is currently evaluating options for future field development including field extensions along the trend, in-fill drilling, and stimulation work on existing wells to increase production and reserves. 6 refs., 34 figs.

  4. Independent life history evolution between generations of bivoltine species: a case study of cyclical parthenogenesis.

    Hood, Glen R; Ott, James R

    2017-04-01

    Successive generations of bi- and multivoltine species encounter differing biotic and abiotic environments intra-annually. The question of whether selection can independently adjust the relationship between body size and components of reproductive effort within successive generations in response to generation-specific environmental variation is applicable to a diversity of taxa. Herein, we develop a conceptual framework that illustrates increasingly independent life history adjustments between successive generations of taxa exhibiting complex life cycles. We apply this framework to the reproductive biology of the gall-forming insect, Belonocnema treatae (Hymenoptera: Cynipidae). This bivoltine species expresses cyclical parthenogenesis in which alternating sexual and asexual generations develop in different seasons and different environments. We tested the hypotheses that ecological divergence between the alternate generations is accompanied by generational differences in body size, egg size, and egg number and by changes in the relationships between body size and these components of reproductive effort. Increased potential reproductive effort of sexual generation B. treatae is attained by increased body size and egg number (with no trade-off between egg number and egg size) and by a significant increase in the slope of the relationship between body size and potential fecundity. These generation-specific relationships, interpreted in the context of the model framework, suggest that within each generation selection has independently molded the relationships relating body size to potential fecundity and potential reproductive effort in B. treatae. The conceptual framework is broadly applicable to comparisons involving the alternating generations of bi- and multivoltine species.

    One of the most hazardous diseases that is commonly associated with the coal mining industry is Silicosis which caused by dust inhalation. This disease occurs as a result of prolonged breathing of dust containing silica (quartz). The generation of coal mine dust during underground and surface coal mining is the most significant source of coal dust exposure. Silica dust develops scar tissue inside the lungs which reduces the lungs ability to extract oxygen from the air. All miners working in underground and surface coal mines are at risk of being exposed to mine dust containing silica. In this study, cases with pathologic diagnosis of silicosis during seven years period between 2000 and 2007 were retrieved, from the pathologic file of Department of Pathology, Massih Daneshvary Hospital in Iran. Results of this case study showed the great effects of dust exposure and inhalation from the viewpoint of symptoms especially between the miners.

    2013-04-23

    A historical examination of a nursing curriculum is a bridge between past and present from which insights to guide curriculum development can be gleaned. In this paper, we use the case study method to examine how the University of Victoria School of Nursing (UVic SON), which was heavily influenced by the ideology of second wave feminism, contributed to a change in the direction of nursing education from task-orientation to a content and process orientation. This case study, informed by a feminist lens, enabled us to critically examine the introduction of a "revolutionary" caring curriculum at the UVic SON. Our research demonstrates the fault lines and current debates within which a feminist informed curriculum continues to struggle for legitimacy and cohesion. More work is needed to illuminate the historical basis of these debates and to understand more fully the complex landscape that has constructed the social and historical position of women and nursing in Canadian society today.

    Purpose (1) To explore the role of native voice and effects of voice loss on self-concept and identity, and survey the state of assistive voice technology; (2) to establish the moral case for developing personalized voice technology. Methods This narrative review examines published literature on the human significance of voice, the impact of voice loss on self-concept and identity, and the strengths and limitations of current voice technology. Based on the impact of voice loss on self and identity, and voice technology limitations, the moral case for personalized voice technology is developed. Results Given the richness of information conveyed by voice, loss of voice constrains expression of the self, but the full impact is poorly understood. Augmentative and alternative communication (AAC) devices facilitate communication but, despite advances in this field, voice output cannot yet express the unique nuances of individual voice. The ethical principles of autonomy, beneficence and equality of opportunity establish the moral responsibility to invest in accessible, cost-effective, personalized voice technology. Conclusions Although further research is needed to elucidate the full effects of voice loss on self-concept, identity and social functioning, current understanding of the profoundly negative impact of voice loss establishes the moral case for developing personalized voice technology. Implications for Rehabilitation Rehabilitation of voice-disordered patients should facilitate self-expression, interpersonal connectedness and social/occupational participation. Proactive questioning about the psychological and social experiences of patients with voice loss is a valuable entry point for rehabilitation planning. Personalized voice technology would enhance sense of self, communicative participation and autonomy and promote shared healthcare decision-making. Further research is needed to identify the best strategies to preserve and strengthen identity and sense of

    2009-09-01

    Non-convulsive status epilepticus can result in significant morbidity and mortality. The condition can be difficult to recognise, and can mimic delirium due to other underlying pathologies. There are several clinical subtypes, although these can be difficult to distinguish by their clinical features alone. Electroencephalogram is the key diagnostic tool to making the diagnosis, but this investigation is a limited resource in many institutions. In this review, we present a case of non-convulsive status epilepticus, manifesting as delirium, and then proceed to a literature review on this important diagnosis.

    Our objective was to study the clinical characteristics and natural history of monomelic amyotrophy (MMA). We used a retrospective study of 279 patients diagnosed to have either upper (Hirayama disease) or lower limb MMA. Results showed that brachial MMA (BMMA) occurred in 224 patients (male:female, 9:1). Mean age of onset was 19.5 ± 4.18 years. Progression occurred over less than five years in the majority (95.9%) of patients. Duration at the last follow-up was: up to five years in 61.4%, 5-10 in 21.3%, 10-15 in 7.2%, > 15 years in 10.1%. MRI showed asymmetrical lower cervical cord atrophy in 44.6% of patients. Crural MMA (CMMA) occurred in 55 patients (male:female, 13:1). Mean age of onset was 21.38 ± 5.3 years. Similar to BMMA, most cases (65.5%) had onset between 15 and 25 years of age. Total duration of illness at the last follow-up was up to five years in 52.7%, 10 and beyond in 47.3%. In conclusion, a large cohort of patients with monomelic amyotrophy seen over 35 years (1976-2010) is described. Study data support the clinical findings and its natural history with long term follow-up, and the findings emphasize that monomelic amyotrophy is a 'benign' condition with a self-limiting course.

  17. The Case for a Hot Archean Climate and its Implications to the History of the Biosphere

    2015-01-01

    The case for a much warmer climate on the early Earth than now is presented. The oxygen isotope record in sedimentary chert and the compelling case for a near constant isotopic oxygen composition of seawater over geologic time support thermophilic surface temperatures prevailing in the Archean, with some support for hot conditions lasting until about 1.5 billion years ago, aside from lower temperatures including glacial episodes at 2.1-2.4 Ga and possibly an earlier one at 2.9 Ga. Other evidence includes the following: 1) Melting temperatures of proteins resurrected from sequences inferred from robust molecular phylogenies give paleotemperatures at emergence consistent with a very warm early climate. 2) High atmospheric pCO2 levels in the Archean are consistent with high climatic temperatures near the triple point of primary iron minerals in banded iron formations, the formation of Mn-bicarbonate clusters leading to oxygenic photosynthesis and generally higher weathering intensities on land. These higher weat...

    Heterotopic pregnancy refers to the simultaneous development of an intrauterine pregnancy and an extrauterine pregnancy. We experienced a case of a ruptured heterotopic pregnancy for a patient with a history of a right segmental salpingectomy from an ectopic pregnancy. The 30-year-old patient with amenorrhea for six weeks complained of lower abdominal pain with hypovolemic shock. Transabdominal ultrasonography showed diffuse hemoperitoneum with a structure similar to an ectatic tube or a deformed cyst with no echogenic double ring or peripheral hypervascularity in the right adnexa and an intrauterine gestational sac. We considered a ruptured corpus luteum cyst as an ultrasonographic finding and found a ruptured tubal mass in the right salpinx and hemoperitoneum through an emergency laparotomy. We performed a right salpingectomy, and the histopathologic report confirmed ectopic pregnancy.

    2010-10-01

    Full Text Available This article sets contemporary challenges to good water governance in South Africa within an important historical context. While it is correct to say that 'the world water crisis is a crisis of governance', it is problematic to assume that all states can follow a similar path toward environmentally sustainable, economically efficient and socially equitable water resources governance and management. The nexus of decision-making power varies within and beyond states, and over time. Gramsci (1971 describes this as the "constellation of social forces". Where this constellation of social forces achieves consensus, a 'historic bloc' is said to emerge giving rise to a particular state form. The South African state form has varied greatly over several centuries, giving rise to various historic blocs. The resulting body of laws and policies and the varied forms of infrastructure that were developed to harness water for multiple social practices over time constitute a complex political ecological terrain not easily amenable to oversimplified frameworks for good water governance. This article outlines the role of water in the history of South Africa’s multiple state forms. It shows that over time, water policy, law and institutions came to reflect the increasingly complex needs of multiple actors (agriculture, mining, industry, cities, the newly enfranchised represented by different state forms and their characteristic political regimes: the Dutch East India Company; the British Empire; the Union of South Africa; the apartheid and post-apartheid republics. Authoritarian, semi-authoritarian and democratic state forms have all used central-state power to serve particular interests. Through time, this constellation of social forces has widened until, today, the state has taken upon itself the task of providing "some water for all forever" (slogan of the Department of Water Affairs. As this article suggests, despite the difficult challenges presented by a

    The National Institute for Occupational Safety and Health (NIOSH) Pittsburgh Research Laboratory (PRL), RAG Pennsylvania and Strata Control Technologies of Australia collaborated in an intensive study of ground behavior, reinforcement performance, and stress redistribution at the Emerald Mine in Southwestern Pennsylvania. The study site was a longwall tailgate subjected to a severe horizontal stress concentration. Field measurements indicated that the stresses applied to the study site nearly doubled during longwall mining, resulting in roof deformations extending to a height of 4.8 m (16 ft) above the entry. A computer simulation of the field site was conducted using FLAC-2D, incorporating a broad range of rock behaviors and failure mechanisms. Comparison between the measurements and the simulation showed that the model was able to capture the most significant aspects of the roof and support system behavior, particularly, the extensive slip along bedding that created a partially destressed 'softened' zone in the immediate roof. The model also showed that supplementing the normal roof bolt support pattern with cable bolts would allow the entry to survive a further 20-25% increase in the applied horizontal stress. Such information could have very practical application to the design of roof support systems for coal mines.

    Prior studies suggest that history of allergy and infections early in life might be inversely associated with cancer. We explored the association between allergies, recent influenza infections and laryngeal cancer risk. We used data from a case-control study which included 229 cases of laryngeal cancer and 769 population controls matched for age and sex. History of a physician-diagnosed allergy, influenza-like infections in the past 5 years, smoking, alcohol consumption and occupational exposure to carcinogens were self-reported. Allergies were classified into two groups (Type I and Type IV), according to the underlying immunologic mechanism. Conditional logistic regression models were fitted using laryngeal cancer as the outcome, adjusting for smoking, alcohol consumption and occupational exposure and stratified for age and sex. Having any allergy was not associated significantly with laryngeal cancer. Although Type I and Type IV allergies were non-significantly associated with laryngeal cancer, Type IV allergies showed a strong inverse association after adjusting for smoking and alcohol (OR 0.50, 95 % CI 0.22-1.2). Participants who reported at least one influenza-like infection during the past 5 years were significantly less likely to have laryngeal cancer (OR 0.57, 95 % CI 0.39-0.81). After considering fever (≥38.5 °C) as a criterion for influenza infection, the association between influenza infection and laryngeal cancer was even stronger (OR 0.29, 95 % CI 0.13-0.63). We found no significant association between any allergy and laryngeal cancer, some indication of an inverse association between Type IV allergy and laryngeal cancer, whereas recent influenza infections were inversely associated with laryngeal cancer risk.

    Technology-led innovation represents an important driver of European economic and industrial competitiveness and offers solutions to societal challenges. In order to facilitate responsible innovation and public acceptance, a need exists to identify and implement oversight approaches focused on the effective risk governance of emerging technologies. This article describes a foresight study on the governance of new technologies, using nanotechnology as a case example. Following a mapping of the governance landscape, four plausible foresight scenarios were developed, capturing critical uncertainties for nanotechnology governance. Key governance elements were then stress tested within these scenarios to see how well they might perform in a range of possible futures and to inform identification of the strengths, weaknesses, opportunities, and threats for nanotechnology governance in Europe. Based on the study outcomes, recommendations are proposed regarding the development of governance associated with the responsible development of new technologies.

    Two hundred and twenty head of pregnant cows were fed virtually 100% fanweed (Thlaspi arvense) in November 1984. One hundred became distressed and colicy within 4 hr of feeding. Eight died over the next 5 days despite removal of the feed and symptomatic treatment. Necropsy revealed massive submucosal edema of the wall of the forestomachs, particularly the rumen. Four abortions occurred. The feed was analyzed and was found to liberate 250 mg/100g of AITC. Possible methods of treatment were devised in case the problem should recur. Fanweed contains sinigrin and the enzyme myrosin. When the plant is crushed and moistened, allylisothiocyanate (AITC) is formed along with glucose and potassium acid sulfate. Application of Le Chatelier's principle led to an investigation of the effect of pH on in vitro generation of AITC. Methods of destroying AITC were also examined, and detoxification studies were undertaken on fanweed.

    Air quality control by a system of monitoring station is indispensable for the environmental protection. Moreover, a monitoring network have not to be only a mere data collection a good air quality control is possible only if the network management allows to prevent unacceptable pollutants level. In other terms, elaboration and interpretation data are fundamental in order to make monitoring system really able for regulations of corrective measures as, for example, the reduction of local emissions. The case of monitoring network run from the Industrial Society CIPA of Siracusa (Italy) is discussed. The management of the data obtained from a continuous survey allows to keep pollutants level below the current limits set down by the Italian law. Furthermore, elaboration of the data allows useful evaluations about atmospheric dispersion phenomena. (author)

    Full Text Available This article discusses the way Islam transformed into an ideology that potentially used as justification for violence. By analising the case of the murder of Teungku Ayub, leader of a small circle for basic religious learning (pengajian in Bireun, Aceh, in 2012, the study reveals to the role of Islam as an ideology of mass movement to cleanse deviant tenet (aliran sesat among the Acehnese. This is because of two reasons. First, the term of the veranda of Mecca (serambi Mekkah remains considered as “holy word” in the Acehnese society today, which supports any Islamic agenda of purifying Aceh from aliran sesat. Secondly, the adoption of Islam into a formal body of state (Aceh province represented by the implementation of Islamic law (sharīʻah. Both reasons above strengthen ulama in Aceh to facilitate the mass movement in the name of religion as well as the rationale background of the murder of Teungku Ayub.

  11. Prolonged Unilateral Disuse Osteopenia 14 Years Post External Fixator Removal: A Case History and Critical Review

    Directory of Open Access Journals (Sweden)

    Karen M. Knapp

    2010-01-01

    Full Text Available Disuse osteopenia is a complication of immobilisation, with reversal generally noted upon remobilisation. This case report focuses on a patient who was seen 18 years following a road traffic collision when multiple fractures were sustained. The patient had an external fixator fitted for a tibia and fibula fracture, which remained in situ for a period of 4 years. Following removal, the patient was mobilised but, still required a single crutch to aid walking. Fourteen years post removal of the fixator, the patient had a DXA scan which, demonstrated a T-score 2.5 SD lower on the affected hip. This places the patient at an increased risk of hip fracture on this side, which requires monitoring. There appear to be no current studies investigating prolonged disuse-osteopenia in patients following removal of long-term external fixators. Further research is required to quantify unilateral long-term effects to bone health and fracture risk in this population.

    Orofacial myologists are frequently called upon to address retained oral habit concerns. During this process, current I.A.O.M. recommended treatment includes addressing tongue, lip, and jaw rest posture concerns. Following digit sucking remediation, we may also be called upon to address these rest posture issues, and tongue thrust more aggressively together. In this process, facial growth and development and jaw structure may coincidentally improve as a result of 'nature taking its course' by addressing both swallow AND rest posture. In a select subset of clients, dramatic improvements may occur if the timing is right. This article discusses one such case that appears to have yielded a significant improvement in oral postures influencing improved facial and oral growth and development.

  13. An Orchestrating Evaluation of Complex Educational Technologies: a Case Study of a CSCL System

    Luis P. Prieto

    2014-06-01

    Full Text Available As digital technologies permeate every aspect of our lives, the complexity of the educational settings, and of the technological support we use within them, unceasingly rises. This increased complexity, along with the need for educational practitioners to apply such technologies within multi-constraint authentic settings, has given rise to the notion of technology-enhanced learning practice as “orchestration of learning”. However, at the same time, the complexity involved in evaluating the benefits of such educational technologies has also increased, prompting questions about the way evaluators can cope with the different places, technologies, informants and issues involved in their evaluation activity. By proposing the notion of “orchestrating evaluation”, this paper tries to reconcile the often disparate “front office accounts” of research publications and the “shop floor practice” of evaluation of educational technology, through the case study of evaluating a system to help teachers in coordinating computer-supported collaborative learning (CSCL scenarios. We reuse an internationally-evaluated conceptual framework of “orchestration aspects” (design, management, adaptation, pragmatism, etc. to structure the case‟s narrative, showing how the original evaluation questions and methods were modulated in the face of the multiple (authentic evaluation setting constraints.

    2015-02-01

    Health technology forecasting is designed to provide reliable predictions about costs, utilization, diffusion, and other market realities before the technologies enter routine clinical use. In this article we address three questions central to forecasting's usefulness: Are early forecasts sufficiently accurate to help providers acquire the most promising technology and payers to set effective coverage policies? What variables contribute to inaccurate forecasts? How can forecasters manage the variables to improve accuracy? We analyzed forecasts published between 2007 and 2010 by the ECRI Institute on four technologies: single-room proton beam radiation therapy for various cancers; digital breast tomosynthesis imaging technology for breast cancer screening; transcatheter aortic valve replacement for serious heart valve disease; and minimally invasive robot-assisted surgery for various cancers. We then examined revised ECRI forecasts published in 2013 (digital breast tomosynthesis) and 2014 (the other three topics) to identify inaccuracies in the earlier forecasts and explore why they occurred. We found that five of twenty early predictions were inaccurate when compared with the updated forecasts. The inaccuracies pertained to two technologies that had more time-sensitive variables to consider. The case studies suggest that frequent revision of forecasts could improve accuracy, especially for complex technologies whose eventual use is governed by multiple interactive factors.

    2017-04-01

    The history of Melito Irpino, a small village in southern Italy is particular, though not unique in its genre. The development of its urban asset was, in fact, strongly affected by natural disasters such as hydrogeological and seismic events, which determined its transfer to another location. Due to its landslides and flooding it has been included since the beginning of the twentieth century among the unstable centers to be consolidated. The landslides were caused by peculiar geological characteristics of which the substrate essentially origins from different consistency Flysch elements. From the seismic point of view, Melito Irpino is part of the first category of the new seismic classification of the Campania Region. The most devastating earthquakes that damaged Melito date back to December 1456, which hit central and southern Italy and 5th June , 1688 which had the Sannio as epicentral area, both with l0 = XI MCS and M> 7 [1456: l0= XI MCS, Mw 7.2; 1688: l0 = XI MCS, Mw 7.O.] During the twentieth century, it was involved in two other disastrous earthquakes that caused serious damage to the village in 1930 with an intensity VIII and in 1962 with I = IX MCS and VIII ESI-07 intensity. The earthquake of 21st August 1962 was fatal for the village of Melito. In December of the same year it was left with 2182 inhabitants and 800 houses, most of which were unstable, 300 were to be demolished, 50 unrepairable and 200 were still uninhabitable yet repairable. From a geological point of view the situation turned even more dramatically when the whole valley area stretching from the old Ufita River bridge and the historical center of Melito was affected by a series of large slope instability such as rock falls, complex rotational slip, de facto complicating an extremely compromised situation. This was sufficient to encourage the transfer of the entire village in an other location. After more than half a century and considering the effects of two important earthquakes in 1962

  16. Cathodic protection of reinforced concrete structure using discrete anode strips -- case history

    2000-07-01

    Cathodic protection of reinforcing steel suffering from chloride-induced corrosion has been used for at least the last decade. It has been demonstrated to be the most appropriate, cost-effective and reliable repair option when compared to conventional repair methods. This case study describes the actions taken on a bridge substructure in the Netherlands, built in 1938 as the major structural support for a balance bridge, where a condition assessment revealed that reinforcement corrosion had been initiated by chloride penetration and carbonation. Cathodic protection with impressed current was proposed to protect the reinforcing steel. The system was based on discrete titanium anode strips, inserted perpendicular to the concrete surface. In order to achieve a uniform distribution of protective current, a system of an average of 10 strips per square meter of concrete surface was placed in holes drilled to a depth of 35 cm. In view of the innovative nature of the design and the heightened risk of non-uniform current distribution, provisions were made for additional monitoring of the performance of the cathodic system. Measurements included concrete resistance, current distribution over the concrete surface and frequent depolarization. Monitoring results revealed a pronounced non-uniform current distribution over the concrete surface and a high current demand in one particular zone. The pronounced differences encountered in this instance were attributed to delaminations and macroscopic cracks in the concrete cover, severely limiting the flow of protective current to the reinforcement. It is suggested that repair of the delaminations by injecting a low resistivity cementitious grout, thereby allowing the use of a more cost-effective surface-mounted anode system might have been a more appropriate option than the one chosen. The principal lesson learned from this particular case is the strong need for quantitative information regarding anodic and cathodic current

    2015-01-15

    The world is seemingly facing a global increase in people suffering from diabetes especially in developing countries. The worldwide occurrence of diabetes for all age groups in year 2000 was estimated to be 2.8% and this number is most certainly expected to rise to 4.4% by 2030. Maturity-onset of diabetes of the young, or MODY, is a form of monogenic diabetes that is caused by mutations occurring in a number of different genes. Mutations in different genes tend to cause a slightly different variant of diabetes. MODY is typically diagnosed during late childhood, adolescence, or early adulthood and is usually observed to develop in adults during their late 50's. One of the main drawbacks in its diagnosis is that many people with MODY are misdiagnosed as having type 1 or type 2 diabetes. However, a molecular and genetic diagnosis can result in a better treatment and could also help in identifying other family members with MODY. This article explores the historical prospect and the genetic background of MODY, a brief summary of the first case reported and the significant factors that differentiate it from type 1 and type 2 diabetes.

    Two adult female rock hyraxes (Procavia capensis) at the Dallas Zoo were confirmed with spontaneous diabetes mellitus from 1997-2000, whereas a third animal with a similar clinical presentation never became hyperglycemic. The pancreas in all three animals showed pancreatic islet fibrosis (PIF). Retrospective examination of medical records for rock hyraxes acquired by this collection or born into it from 1991-2002 identified eight more animals affected with PIE All affected animals, including three males and eight females, were 1-7 yr of age and presented either with vague clinical signs of soft feces and rough hair coat or were acutely moribund or dead. Clinical pathology data was available for seven of the animals before onset of overt clinical signs and revealed inappropriate hyperglycemia in six, as well as elevated serum concentrations of creatine phosphokinase, amylase, and lipase in all seven animals. Pedigree evaluation did not support a familial pattern for PIE Review of the histopathology findings from nine other zoologic collections with rock hyrax deaths during the study period identified six institutions with 12 additional cases genetically unrelated to the incident collection. Histopathology and viral serology did not support an infectious cause. Analysis of serum anti-islet and anti-insulin antibodies did not suggest autoimmune disease, and none of the animals had known exposure to toxic substances. Limited nutritional analyses did not support a nutritional basis for the condition, and the cause for PIF remains unknown.

    Full Text Available The paper presents and analyses the laws and other legal documents as well as standards, guidelines and codes of library profession related to the local history collection creation and development at the public library. The Croatian laws on electronic media and copyright are also analysed because the paper describes the case study of audio materials which were created as part of the radio program of the local radio station. Such materials are local in nature and therefore surely belong to the local history library collection. Since this type of material is not directly regulated in legislation, the paper offers a starting point for such cases to be included in public libraries local history collections. The case study shows the destiny of radio program named U četiri ćoška by Ivan Herman which was aired on the Croatian Radio Županja.

    Smallpox inoculation was one of the great discoveries of the 18th century and has been written into the grand narrative of medical progress, describing the taming of epidemic disease. Setting the perspective of progress aside, the article explores how this medical innovation was situated in 18th-century society and culture. The aim is to investigate how medical practice was intertwined with social structure and cultural patterns. The article takes its case from a book published in Copenhagen in 1766 by Professor C. F. Rottböll, former Head Physician of the Royal Inoculation House in Copenhagen. Being the first medical treatise on inoculation in Denmark-Norway, the book also has a historical section followed by a collection of reports and letters written by a number of other authors from various parts of the kingdom. Through close reading, the article explores how the introduction of the new technique was described in the texts. The reports were written to present practice and discuss cases. In doing so, they also presented a variety of other concerns so that a diversity of aims and intentions are added to the medical ones. The social and rhetorical strategies employed illuminate social ambition and systems of patronage, as well as understandings of history and of truth.

    We report on a boy with Pallister-Killian syndrome (PKS) who was conceived by assisted reproductive technology (ART), specifically in vitro fertilization (IVF) with parents' gametes. A prenatal diagnosis performed elsewhere by CVS failed to detect the presence of the isochromosome 12p that was demonstrated postnatally in approximately 50% of cultured skin fibroblasts. Given that the patient did not show the congenital overgrowth typical of PKS, we speculate that ART might have restricted overgrowth in this particular case. More broadly, we hypothesize that overgrowth might protect from early demise fetuses conceived by ART, a technology known to cause low and very low birth weight.

    Full Text Available Governmental data are being published in many countries, providing an unprecedented opportunity to create innovative services and to increase societal awareness about administration dynamics. In particular, semantic technologies for linked data production and exploitation prove to be ideal for managing identity and interoperability of administrative entities and data. This paper presents the current state of art, and evolution scenarios of these technologies, with reference to several case studies, including two of them from the Italian context: CNR's Semantic Scout, and DigitPA's Linked Open IPA.

  7. Stress history controls the spatial pattern of aftershocks: case studies from strike-slip earthquakes

    Earthquake ruptures perturb stress within the surrounding crustal volume and as it is widely accepted now these stress perturbations strongly correlates with the following seismicity. Here we have documented five cases of the mainshock-aftershock sequences generated by the strike-slip faults from different tectonic environments of world in order to demonstrate that the stress changes resulting from large preceding earthquakes decades before effect spatial distribution of the aftershocks of the current mainshocks. The studied mainshock-aftershock sequences are the 15 October 1979 Imperial Valley earthquake (Mw = 6.4) in southern California, the 27 November 1979 Khuli-Boniabad (Mw = 7.1), the 10 May 1997 Qa'enat (Mw = 7.2) and the 31 March 2006 Silakhor (Mw = 6.1) earthquakes in Iran and the 13 March 1992 Erzincan earthquake (Mw = 6.7) in Turkey. In the literature, we have been able to find only these mainshocks that are mainly characterized by dense and strong aftershock activities along and beyond the one end of their ruptures while rare aftershock occurrences with relatively lower magnitude reported for the other end of their ruptures. It is shown that the stress changes resulted from earlier mainshock(s) that are close in both time and space might be the reason behind the observed aftershock patterns. The largest aftershocks of the mainshocks studied tend to occur inside the stress-increased lobes that were also stressed by the background earthquakes and not to occur inside the stress-increased lobes that fall into the stress shadow of the background earthquakes. We suggest that the stress shadows of the previous mainshocks may persist in the crust for decades to suppress aftershock distribution of the current mainshocks. Considering active researches about use of the Coulomb stress change maps as a practical tool to forecast spatial distribution of the upcoming aftershocks for earthquake risk mitigation purposes in near-real time, it is further suggested that

    Full Text Available We have given a critical analysis of statistical models and methods for processing text information in historical records to establish the times when there were certain events, ie, to build science-based chronology. There are three main kinds of sources of knowledge of ancient history: ancient texts, the remains of material culture and traditions. The specific date of the extracted by archaeologists objects in most cases can not be found. The group of Academician A.T. Fomenko has developed and applied new statistical methods for analysis of historical texts (Chronicle, based on the intensive use of computer technology. Two major scientific results were: the majority of historical records that we know now, are duplicated (in particular, chronicles, describing the so-called "Ancient Rome" and "Middle Ages", talking about the same events; the known historical chronicles tell us about real events, separated from the present time for not more than 1000 years. It was found that chronicles describing the history of "ancient times" and "Middle Ages" and the chronicle of Chinese history and the history of various European countries do not talk about different, but about the same events. We have the attempt of a new dating of historical events and restoring the true history of human society based on new data. From the standpoint of statistical methods of historical records and images of their fragments – they are special cases of non-numeric objects of nature. Therefore, developed by the group of A.T. Fomenko computer-statistical methods are the part of non-numerical statistics. We have considered some methods of statistical analysis of chronicles applied by the group of A.T. Fomenko: correlation method of maximums; dynasties method; the method of attenuation frequency; questionnaire method codes. New chronology allows us to understand much of the battle of ideas in modern science and mass consciousness. It becomes clear the root cause of cautious

  20. Primary Dermal Melanoma in a Patient with a History of Multiple Malignancies: A Case Report with Molecular Characterization

    Directory of Open Access Journals (Sweden)

    Germana Sini

    2013-07-01

    Full Text Available Introduction: Primary dermal melanoma (PDM is a recently described clinical entity accounting for less than 1% of all melanomas. Histologically, it is located in the dermis or subcutaneous tissue, and it shows no connections with the overlying epidermis. The differential diagnosis is principally made along with that of metastatic cutaneous melanoma. Case Report: A 72-year-old Caucasian woman with a history of multiple cancers (metachronous bilateral breast cancer, meningioma, clear cell renal cell carcinoma, uterine fibromatosis and intestinal adenomatous polyposis, came to our attention with a nodular lesion on her back. After removal of the lesion, the histology report indicated malignant PDM or metastatic malignant melanoma. The clinical and instrumental evaluation of the patient did not reveal any other primary tumour, suggesting the primitive nature of the lesion. The absence of an epithelial component argued for a histological diagnosis of PDM. Subsequently, the patient underwent a wide surgical excision with sentinel node biopsy, which was positive for metastatic melanoma. Finally, the mutational status was studied in the main genes that regulate proliferation, apoptosis and cellular senescence. No pathogenetic mutations in CDKN2A, BRAF, NRAS, KRAS, cKIT, TP53 and PTEN genes were observed. This suggests that alternative pathways and low-frequency alterations may be involved. Conclusions: The differential diagnosis between PDM and isolated metastatic melanoma depends on the negativity of imaging studies and clinical findings for other primary lesions. This distinction is important because 5-year survival rates in such cases are higher than in metastatic cases (80-100 vs. 5-20%, respectively.
