  1. Promoting astronomy in developing countries: A historical perspective

    Any international effort to promote astronomy world wide today must necessarily take into account its cultural and historical component. The past few decades have ushered in an age, which we may call the Age of Cultural Copernicanism. In analogy with the cosmological principle that the universe has no preferred location or direction, Cultural Copernicanism would imply that no cultural or geographical area, or ethnic or social group, can be deemed to constitute a superior entity or a benchmark for judging or evaluating others. In this framework, astronomy (as well as science in general) is perceived as a multi-stage civilizational cumulus where each stage builds on the knowledge gained in the previous stages and in turn leads to the next. This framework however is a recent development. The 19th century historiography consciously projected modern science as a characteristic product of the Western civilization decoupled from and superior to its antecedents, with the implication that all material and ideological benefits arising from modern science were reserved for the West. As a reaction to this, the orientalized East has often tended to view modern science as "their" science, distance itself from its intellectual aspects, and seek to defend, protect and reinvent "our" science and the alleged (anti-science) Eastern mode of thought. This defensive mindset works against the propagation of modern astronomy in most of the non-Western countries. There is thus need to construct a history of world astronomy that is truly universal and unselfconscious. Similarly , the planetarium programs , for use the world over, should be culturally sensitive. IAU can help produce cultural-specific modules. Equipped with this paradigmatic background, we can now address the question of actual means to be adopted for the task at hand. Astronomical activity requires a certain minimum level of industrial activity support. Long-term maintenance of astronomical equipment is not a trivial task

  2. Historical perspective

    1982-01-01

    A historical perspective of the nuclear waste issue is presented, beginning from the Atoms for Peace Legislation which made nuclear technology available to private industry in 1953 to 1954. Once the nuclear process had been demonstrated to be a technically and economically feasible method to convert thermal energy for electric power generation, commercial application began. The issue of nuclear waste management did not keep up with higher priorities. As early as 1957, research into storing the waste in geological structures was conducted by the National Academy of Sciences, and considerable technical progress was made in the 60's. During the 60's and 70's, numerous legislative actions (e.g., Clean Air Act, Clean Water Act, Environmental Policy Act) had a significant impact on nuclear waste dipsosal decisions. In 1971 to 1972 the Atomic Energy Commission authorized a nuclear waste repository in Kansas, a decision which was amended the following year and finally abandoned altogether in 1974. The OPEC oil embargo and ensuing price actions moved nuclear power into a more prominent position in the United States' plans for energy independence. This increased the stress between environmental concerns and economic need. The Carter Administration indefinitely deferred reprocessing of spent fuel and initiated a government-wide review of nuclear policy issues. The Congress did not actively begin to fashion a nuclear waste program until February 1980. The legislation which passed the Senate in the Spring of '82, and a compromise version pending before the House, may resolve the issue by establishing a long-term stable policy which will contain milestones, goals and specific decision making processes; it will include a mechanism for the public and the states to be involved; and it will insure adequate financing provisions

    Landsberg, H. E.

    It was a pleasure to learn, from a recent (May 4) issue of Eos, of the formation of a permanent Committee on History of Geophysics. There is a dire need for reference material, books, and articles on geophysical history.Let me recommend to them that they take a good look at the Dictionary of the History of Science (W.F. Bynum, E.J. Browne, Roy Porter (Eds.), Princeton University Press, 494 pp., 1981). What follows is not a book review, although it may appear so. It is meant to be a challenge to place geophysics on the map in historical context. In this book, hydrology is dealt with in one sentence under the heading ‘cycle,’ geomagnetism under ‘declination and dip,’ and its history ends with Edward Sabine. Seismology appears under earthquakes. No important seismologist is mentioned. In the biographical index, Wiechert is included only for a contribution to physics. Where are Sir Harold Jeffreys, Galitzin, Gutenberg, Mohorovičić, Lehman, and many others? Meteorology ends with V. Bjerknes and Solberg; Köppen, Richardson, Rossby, and other notables [of] the last century do not seem to exist.

  4. Einstein: A Historical Perspective

    In late 1915, Albert Einstein (1879-1955) completed as series of papers on a generalized theory of gravitation that were to constitute a major conceptual change in the history of modern physics and the crowning achievement of his scientific career. But this accomplishment came after a decade of intense intellectual struggle and was received with muted enthusiasm. Einstein's previously unpublished writings and massive correspondence, edited by the Einstein Papers Project, provide vivid insights into the historical, personal, and scientific context of the formulation, completion, and reception of GR during the first decades of the 20th century.

  5. Basavarajeeyam: A historical perspective.

    Nishteswar, K

    2011-10-01

    Basavarajeeyam is an important handbook for an Ayurvedic physician of Andhra region. It is a bilingual work and the content was presented in Sanskrit and Telugu languages. With regard to the place and date of Basavarajeeyam there is no common opinion among the present day scholars. Pt Govardhana Sharma Changani in his introduction to the Sanskrit version of Basavarajeeyam exposed a historical profile of Basavrajeeyam picturising him as Basava who was a staunch follower of Veerashaivism and a contemporary of king Bijjala (end of 12(th) cent. AD). The same statement is carried out in the works of Ayurvedic Itihasa written by Atredeva Vidyawalkan and Acharya Priyavrata Sharma. It appears that the historical evidence shown by these scholars is one sided and cannot stand any reason. Basavraju stated that he had started writing this work after a thorough study of many works such as Charaka, Nithyanatheeyam (1360 AD), Revenakalpam, Pujyapadiyam, Bahatam, Kashikhandam (1435 AD) etc. Basavraju has faithfully reproduced certain chapter of Vaidyachintamani, which is considered to be a work of 15(th) century. Basavraju not only mentioned Phirangiroga in the index of diseases described by him at the end of the book, but also indicated Phirangichekka (Madhusnuhi) in the management of Meharoga and Granthi. By this evidence Basavarajiyam should be considered as the work of post Bhavaprakasha period. Basavraju indicates in the Gulmaroga Chikitsa that Sankhadravaka should be administered in the dose of 'Ekanni'. The name Ekanni was given for a copper coin which came in to circulation of money during British India produced from Madras mint (1794 AD). Based on these internal evidences, it can be safely concluded that Basavraju belong to 18(th)century.

  6. Economic Growth and Institutional Reform in Modern Monarchies and Republics: A Historical Cross-Country Perspective 1820-2000

    DEFF Research Database (Denmark)

    Bjørnskov, Christian; Kurrild-Klitgaard, Peter

    Standard theoretical arguments suggest that republics ought to grow faster than monarchies and experience lower transitional costs following reforms. We employ a panel of 27 countries observed from 1820-2000 to explore whether institutional reforms have differential growth effects in monarchies...... and republics. A set of Barro-type regressions show that there are no significant growth differences between the two regime types and that the effects of incremental reforms do not differ between them, but that those of large-scale reforms do. Specifically, we find a strong "valley-of-tears" effect of large...

  7. The INIS Thesaurus: historical perspective

    The INIS Thesaurus is a controlled terminological knowledge base that has been developed over the years through the contribution of INIS Member States in all areas of peaceful applications of nuclear science and technology, which is also the subject scope of the INIS Collection. The thesaurus is primarily used for subject indexing of input into the INIS system and for retrieval of information from the database. Thanks to the vital support of INIS Member States, the thesaurus has been translated into eight languages (i.e. all IAEA official languages plus German and Japanese) and is available online to assist our global users as a tool for retrieval and for general reference. It is a dynamic information resource that is continually updated to cater to new developments of terminologies in nuclear science and technology. Since its inception in the 1960’s, it was decided that the subject analysis for INIS input preparation be based on its own subject categories, which also determines its scope, and keyword indexing using a thesaurus. This article briefly describes the development of the INIS Thesaurus from a historical perspective

    This paper demonstrates in historical and technical perspective how radium began to be used in consumer products and how changing conditions in technology and regulations have greatly modified the use of radium. In addition, the various uses of radium that have been tried or have been used in consumer products have been described, and whenever possible, the historical perspective has been used to show when devices were needed and when changing conditions caused the products to be no longer required. The historical perspective attitude is again used in the evaluation of the risks and benefits of radium in comparison to radium substitutes

  11. VARIETIES OF SOCIAL DISCIPLINING, HISTORICAL PERSPECTIVES.

    Directory of Open Access Journals (Sweden)

    Tomás A. Mantecón Movellán

    2011-04-01

    Full Text Available Historical thought has tended to explain social disciplining according to two main analytical perspectives: on one hand, German tradition about the so-called sozialdisziplinierung and, on the other hand, Foucault perspectives (focussed on disciplines practiced on the bodies-and/or-minds of people by the authorities. From these both viewpoints social disciplining was a dynamic ingredient of change, from traditional societies up to contemporary liberal societies; a machinery to provoke top-down changes (from above. On the bases of historical evidences, this research claims for a third viewpoint that stresses dynamics of social discipline and social disciplining from below; underlines the need of integrating this third perspective in the historical explanation of change in past societies throughout the analysis of social practices of everyday life; the values underneath them and, in the end, taking into account varieties of discipline and perspectives of social disciplining from below.

  12. Plants as De-Worming Agents of Livestock in the Nordic Countries: Historical Perspective, Popular Beliefs and Prospects for the Future

    Directory of Open Access Journals (Sweden)

    Ingebrigtsen K

    2001-03-01

    Full Text Available Preparations derived from plants were the original therapeutic interventions used by man to control diseases (including parasites, both within humans and livestock. Development of herbal products depended upon local botanical flora with the result that different remedies tended to develop in different parts of the world. Nevertheless, in some instances, the same or related plants were used over wide geographic regions, which also was the result of communication and/or the importation of plant material of high repute. Thus, the Nordic countries have an ancient, rich and diverse history of plant derived anthelmintic medications for human and animal use. Although some of the more commonly used herbal de-wormers were derived from imported plants, or their products, many are from endemic plants or those that thrive in the Scandinavian environment. With the advent of the modern chemotherapeutic era, and the discovery, development and marketing of a seemingly unlimited variety of highly efficacious, safe synthetic chemicals with very wide spectra of activities, herbal remedies virtually disappeared from the consciousness – at least in the Western world. This attitude is now rapidly changing. There is a widespread resurgence in natural product medication, driven by major threats posed by multi-resistant pest, or disease, organisms and the diminishing public perceptions that synthetic chemicals are the panacea to health and disease control. This review attempts to provide a comprehensive account of the depth of historical Nordic information available on herbal de-wormers, with emphasis on livestock and to provide some insights on potentially rewarding areas of "re-discovery" and scientific evaluation in this field.

  17. Dermatotoxicology: Historical perspective and advances

    International Nuclear Information System (INIS)

    Ngo, Mai A.; Maibach, Howard I.

    2010-01-01

    The fundamental principles underlying the study of dermatotoxicology were developed by Arnold Lehman and John Draize over a half century ago and remain applicable today. This discipline has proven indispensable for addressing the problems associated with skin exposure to chemicals. The 55th anniversary of Lehman's landmark publication on safety factors presents the opportunity to reflect upon the historical beginnings of dermatotoxicology and the role of regulatory policies on the development of this field over the years. The complexity and sheer volume of information that has been collected makes it difficult to comprehensively cover all aspects of this vast discipline. This overview will touch upon the general concepts of ADME, the various forms of contact dermatitis, and transdermal drug delivery systems. The traditional tests performed in animals and humans to identify allergic or irritant potential of chemicals, in addition to alternative methods such as QSAR modeling will be discussed. The subspecialties of infant and occupational dermatotoxicology, as well as dermatotoxicology of aged and ethnic skin, and skin of the vulva and vagina will also be noted.

    McElroy, J.L.; Bjorklund, W.J.; Bonner, W.F.

    1982-02-01

    The possibility of converting high-level wastes (HLW) to glass was first pursued in Canada and England at a time when other countries were evaluating many other alternatives. By 1966, the British had completed radioactive demonstrations of the FINGAL pot process, converting HLW to borosilicate glass. By this time other countries, including France and the United States, had begun using the glass waste form. Beginning in 1966, several processes, including phosphate and borosilicate glass, were demonstrated by the US in the Waste Solidification Engineering Prototypes (WSEP) program at the Pacific Northwest Laboratory (PNL). Most of the current vitrification processes are adaptations of the FINGAL pot process or the continuous metallic melter used in the WSEP program. One notable exception is the joule-heated ceramic melter, which was adapted from commercial glass technology for HLW by PNL in the mid-1970's. Both batch and continuous processes have been developed to an advanced stage of readiness. These processes are described and compared in this paper

    To chronicle the history of medicine and neurology in India with a focus on its establishment and evolution. THE HISTORY OF NEUROLOGY IN INDIA IS DIVIDED INTO TWO PERIODS: ancient and modern. The ancient period dates back to the mid-second millennium Before Christ (B.C.) during the creation of the Ayurvedic Indian system of Medicine, which detailed descriptions of neurological disorders called Vata Vyadhi. The early 20(th) century witnessed the birth of modern Indian medicine with the onset of formal physician training at the nation's first allopathic medical colleges located in Madras (1835), Calcutta (1835) and Mumbai (1848). Prior to India's independence from Britain in 1947, only 25 medical schools existed in the entire country. Today, there are over 355. In 1951, physicians across the field of neurology and neurosurgery united to create the Neurological Society of India (NSI). Four decades later in 1991, neurologists branched out to establish a separate organization called the Indian Academy of Neurology (IAN). Information was gathered through literature review using PubMed, MD Consult, OVID, primary texts and research at various academic institutions in India. Neurological disorders were first described in ancient India under Ayurveda. The transition to modern medicine occurred more recently through formal training at medical schools beginning in the 1930's. Early pioneers and founders of the NSI (1951) include Dr. Jacob Chandy, Dr. B Ramamurthi, Dr. S. T. Narasimhan and Dr. Baldev Singh. Later, Dr. J. S. Chopra, a prominent neurologist and visionary, recognized the need for primary centers of collaboration and subsequently established the IAN (1991). The future of Neurology in India is growing rapidly. Currently, there are 1100 practicing neurologists and more than 150 post-graduate trainees who join the ranks every year. As the number of neurologists rises across India, there is an increase in the amount of basic, clinical and epidemiological research being

    2005-01-01

    An analysis of scientific standards in parasitology was carried out from the perspective of anthropology of knowledge - a new discipline that emerged from non-classical history science in the 1990s. The history of parasitology, its development and limitations, are presented in a broad socio-cultural context, as the answers of scientists to different social needs in historical periods. In parasitological history there are some periods characteristic for all newly emerging disciplines of natural science. The first systematic account of natural phenomena and their interpretations was initiated in the 16th century and continued till the mid 18th century. It was a period when the phenomena could not be explained in a proper way by the existing and accepted theories. The epidemic diseases were one of these phenomena which were interpreted based on ancient ideas, mostly humoral pathology. In the 16th century a new contagium concept of material factors (pathogenes) that could be spread by contact among humans or close association was formed. This hypothesis, however, was not widely accepted because it contradicted the well-established normative concepts in the European academic naturalism. The development of parasitology was stopped because of theoretical barriers and interpretation difficulties (non-materialistic standard of naturalism, humoral pathology and spontaneous theory). In the second half of the 18th century, the theoretical crisis in natural sciences gave a new impulse for many disciplines; among others, parasitology entered in its second stage of development. The collected observations were classified in a new way and in the context of new interpretations. The progress in parasitology was prompted by the intensified urbanization, rapid increase of European population as well as by wars connected with infections and epidemics. It resulted in two competitive research programs (the French and the German). On the basis of the same observations, they advanced

    Full Text Available In principle any garden reminds us of beauty and unity of nature. But there exist gardens arranged in accordance with the traditional principles of the Islamic Chorbog or architecturally -organized a Four-sides garden which possesses as it seems to me considerably more potential than the gardens planned without such principles. At the present paper an attempt has been made to prove it and it is noted that the Koran is sacred for Moslem people and its references to nature as well as the description of paradise gardens deserves the careful study when considering the meaning of the Islamic gardens. Types and peculiarities of the Islamic countries gardens are also considered in the given paper.

    Full Text Available For a long time the terms basilar invagination and platybasia were used interchangeably. Basilar invagination has been defined as a prolapse of the vertebral column into the spinal cord. Platybasia is defined as an abnormal obtuse angle between the anterior skull base and the clivus. The authors review the existing literature and summarize the historical and modern perspectives in the management of basilar invagination. From radiological curiosities, the subject of basilar invagination is now viewed as eminently treatable. The more pronounced understanding of the subject has taken place in the last three decades when on the basis of understanding of the biomechanical subtleties the treatment paradigm has remarkably altered. From surgery that involved decompression of the region, stabilization and realignment now form the basis of treatment.

    2016-12-01

    Full Text Available The aim of this article is to explore the historical context of vocationalism in universities. It is based on an analysis of the history of the university from a vocational perspective. It looks for evidence of vocational engagement in the activities of universities over time, taking a long view from the birth of the Western University in the Middle Ages to the 1980s with the emergence of current issues of vocationalism in university education. It adopts a chronological perspective initially and then a thematic one. The main findings are: (1 vocationalism in university education is as old as the Western University itself, (2 there is evidence from the start of the Western University of vocational engagement in terms of the provision of vocationally relevant subjects, vocationally relevant skills and the development of vocationally relevant attitudes, (3 whereas most graduate employers used to be concerned with the vocationally relevant knowledge, skills and attitudes students acquired on their degree courses, most are now more concerned with graduate capacity and disposition to learn within their employment after graduation and (4 subject-centred education is compatible with university education that supports the vocational aspirations of students.

  6. Development perspective of transitional countries

    Directory of Open Access Journals (Sweden)

    Ilić Bogdan B.

    2005-01-01

    Full Text Available The end of 20th century witnessed the affirmation and development of information technology as well as the transformation of industrial into information, "new economy", which caused changes in people and circumstances. The role and importance of nonhuman factors was increased, causing entrepreneurship and knowledge-based information to become the most significant resources. The Internet became the basis of the "new economy". It changes the way of doing business, studying, researching, communicating and competition. It also reduces operating costs, crosses national borders and leads to the globalization of the world economy. Transitional countries have to fit into modern development flows by formulating their own strategy of national development and establishing their own competitive advantages in conditions of "new economy". These advantages lie predominantly in highly qualified and skilled younger labor which learns fast and adopts new knowledge and skills, through reducing transactional costs, shortening of certain development stages through which developed countries have already gone, using their experience, scientific-technological progress, a rise in work productivity, etc. Experience of other countries should be innovated and adapted to one's own material and social conditions, not copied. This enables the emergence of "European small tigers", which are similar to "Asian small tigers".

    Crommelinck, M

    2014-10-01

    The aim of this paper is to present a short historical perspective on the neurophysiological approach to hysteria and conversion disorders. The body of this paper will be constituted of three main parts. In the first part, we will present the significant progress due to some pioneers of neurology/psychiatry during the XIXth century. As we shall see, this period was particularly rich in personalities whose work gradually laid the foundations to a true medical approach to hysteria. In the first half of the XXth century, different factors have led to a long eclipse of the neurological approach to hysteria. In the second part, we will show how, by the 1960's-1970's, the conceptual and methodological advances in neurophysiology, as well as the turning point of cognitive sciences (and cognitive psychology in particular) allowed a gradual reinstatement of hysteria within the fields of neurology and clinical neurophysiology. Finally, and this is the third part of this paper, we will show how over the past three decades, an entirely new neurophysiological approach to hysteria and conversion disorders has emerged.

    The standard distinction between poetic and referential language, the gulf between science and the humanities, and the distress many teachers of English feel when faced for the first time with the prospect of teaching technical writing are discussed. In the introduction of many technical writing textbooks. Technical communication is divorced from other forms of linguistic experience by making language limiting and reductive rather than creative and expansive. The emphasis on technical/scientific writing as radically different had blinded people to those traits it has in common with all species of composition and has led to a neglect of research, on fundamental rhetorical issues. A complete rhetorical theory of technical discourse should include information about the attitudes and motives of writers, the situations which motivate (or coerce) them to write, definitive features of technical style and form, interrelationship of expression and creativity, and functions of communication in shaping and preserving scientific networds and institutions. The previous areas should be explored with respect to contemporary practice and within an historical perspective.

  9. Multi-Infarct Dementia: A Historical Perspective

    2017-05-01

    Full Text Available Background: Multi-infarct dementia (MID, a prominent subtype of vascular dementia (VaD, has only achieved recognition in the last 4 decades. Since its original description, the characterization, etiological understanding, and therapeutic direction of MID and other VaD subtypes has progressed at an astounding rate. Summary: This paper divides the landmark discoveries and emergence of new research strategies for MID into decade-defining patterns so that a condensed picture of the total history of MID and its eventual inclusion as a VaD subtype emerges. This paper follows the first descriptive decade, a shift to a preventative focus, a renewed interest coinciding with timely advances in research technology, and a hopeful return to treatment possibilities for VaD. Key Message: Concisely tracing the historical lineage of the modern understanding of MID, both as a singular entity and as part of the VaD con­stellation of disorders, provides a novel perspective on the foundation upon which future advances in combating vascular contributions to dementia will be based.

    The authors propose a perspective on the history of electricity in Europe which notably illustrates both similarities and differences between models and policies in European countries. In a first part, they address the early years of electricity development, between 1880 and 1920, which drove the whole European society and economy. They analyse this success as based on three main issues: a common vision of the role of electricity in the society (a symbol of progress and modernity), a collective work on the technical and economic reality (a community of scientists and engineers working on technological breakthroughs), and propositions regarding institutions and the activity organisation (a common industrial model elaborated by contractors-managers of the electricity sector and proposed to governments). In a second part, the authors address the following period (1920-1980) which is characterized by a diversity of models for the electricity sectors and systems. They highlight the background of these differences, propose a focus on the three main European countries (France, Germany, Great-Britain), and discuss the relationship between this diversity of organisation modes and imageries. The next part addresses the Europe of electricity since the 1980's. The authors outline its technical characteristic, the adoption of a top-down approach since the 1990's, and the lack of consistency in these evolutions, and draw some lessons from the building up of a Europe of electricity since the 1990's. The authors finally question and comment how to build up the Europe of energy again

    The book showcases a selection of peer-reviewed papers, the preliminary versions of which were presented at a conference held 11-13 June 2011 in Bologna and organized jointly by the Italian Statistical Society (SIS), the National Institute of Statistics (ISTAT) and the Bank of Italy. The theme of the conference was "Statistics in the 150 years of the Unification of Italy." The celebration of the anniversary of Italian unification provided the opportunity to examine and discuss the methodological aspects and applications from a historical perspective and both from a national and international point of view. The critical discussion on the issues of the past has made it possible to focus on recent advances, considering the studies of socio-economic and demographic changes in European countries.

    Mom's conventional wisdom of eating fruits and vegetables to lead a healthy life has evolved with scientific, fact-finding research during the past four decades due to advances in science of "Foods for Health". Epidemiological and prospective studies have demonstrated the vital role of fruits, vegetables, and nuts in reducing the risk of cancer and cardiovascular diseases. In recent years, several meta-analyses strongly suggested that by adding one serving of fruits and vegetables to daily diet, the risk of cardiovascular diseases will be decreased up to 7%. The multidisciplinary and partnership efforts of agriculture and medical scientists across the globe stimulated interest in establishing certain interdisciplinary centers and institutes focusing on "Foods for Health". While the consumption of various healthy foods continues, several questions about toxicity, bioavailability, and food-drug interactions of bioactive compounds are yet to be fully understood on the basis of scientific evidence. Recent research on elucidation of the molecular mechanisms to understand the "proof of the concept" will provide the perfect answer when consumers are ready for a "consumer-to-farm" rather than the current "farm-to-consumer" approach. The multidisciplinary research and educational efforts will address the role of healthy foods to improve eye, brain, and heart health while reducing the risk of cancer. Through this connection, this review is an attempt to provide insight and historical perspectives on some of the bioactive compounds from the day of discovery to their current status. The bioactive compounds discussed in this review are flavonoids, carotenoids, curcumin, ascorbic acid, and citrus limonoids.

  13. Stem cells and bone: a historical perspective.

    2015-01-01

    Bone physiology and stem cells were tightly intertwined with one another, both conceptually and experimentally, long before the current explosion of interest in stem cells and so-called regenerative medicine. Bone is home to the two best known and best characterized systems of postnatal stem cells, and it is the only organ in which two stem cells and their dependent lineages coordinate the overall adaptive responses of two major physiological systems. All along, the nature and the evolutionary significance of the interplay of bone and hematopoiesis have remained a major scientific challenge, but also allowed for some of the most spectacular developments in cell biology-based medicine, such as hematopoietic stem cell transplantation. This question recurs in novel forms at multiple turning points over time: today, it finds in the biology of the "niche" its popular phrasing. Entirely new avenues of investigation emerge as a new view of bone in physiology and medicine is progressively established. Looking at bone and stem cells in a historical perspective provides a unique case study to highlight the general evolution of science in biomedicine since the end of World War II to the present day. A paradigm shift in science and in its relation to society and policies occurred in the second half of the XXth century, with major implications thereof for health, industry, drug development, market and society. Current interest in stem cells in bone as in other fields is intertwined with that shift. New opportunities and also new challenges arise.

    Kennard, M.W.; Harbottle, J.E.

    2000-01-01

    Control rod designs and materials have evolved in response to performance problems in both PWRs and BWRs. Irradiation-assisted stress corrosion cracking (IASCC) due to absorber swelling has primarily affected BWR control rods with B 4 C absorbers, but has also occurred in PWRs with Ag-In-Cd absorbers. The primary problems for some designs of PWR control rods have been wear of the rodlets against upper internal components and swelling with tip wear and cracking. Competition amongst vendors for supplying control rod reloads has also resulted in design improvements. This paper provides an historical review of PWR and BWR control rod designs, their problems and remedies. (author)

    The assessment of radiation risk needs to be seen against the background of a historical development that has reversed the initial belief in a general beneficial effect of radiation to apprehension and fear. Numerical risk estimates are, today, based on large epidemiological studies, and the observations on the A-bomb survivors are outlined as the primary source of information. Since the epidemiological findings are obtained from relatively high radiation exposures, extrapolations are required to the much lower doses that are relevant to radiation protection. The evolution of extrapolation procedures up to current attempts at mechanistic modelling is outlined, and some of the open issues are reviewed. (author)

    Over the last 30 years, computation based on molecular models is playing an increasingly important role in biology, biological chemistry and biophysics. Since only a very limited number of properties of biomolecular systems are actually accessible to measurement by experimental means, computer simulation complements experiments by providing not only averages, but also distributions and time series of any definable, observable or non-observable, quantity. Biomolecular simulation may be used (i) to interpret experimental data, (ii) to provoke new experiments, (iii) to replace experiments and (iv) to protect intellectual property. Progress over the last 30 years is sketched and perspectives are outlined for the future.

  11. Women and drug addiction: a historical perspective.

    Science.gov (United States)

    Kandall, Stephen R

    2010-04-01

    The history of women and addiction in America extends back more than 150 years. Although the true epidemiology of women and addiction has always been difficult to determine, the spectrum of female addicts extends well beyond those women who make sensationalistic headlines by "abandoning" or "battering" their children. Historically, female addiction has been largely the result of inappropriate overmedication practices by physicians and pharmacists, media manipulation, or individuals own attempts to cope with social or occupational barriers preventing equality and self-fulfillment. From the mid-nineteenth century, uneasy tolerance, social ostracism, vilification, persecution, and legal prosecution have grudgingly, but not completely, given way to more humane treatment opportunities in the setting of more enlightened comprehensive care.

  12. The population health approach in historical perspective.

    Science.gov (United States)

    Szreter, Simon

    2003-03-01

    The origin of the population health approach is an historic debate over the relationship between economic growth and human health. In Britain and France, the Industrial Revolution disrupted population health and stimulated pioneering epidemiological studies, informing the early preventive public health movement. A century-long process of political adjustment between the forces of liberal democracy and propertied interests ensued. The 20th-century welfare states resulted as complex political mechanisms for converting economic growth into enhanced population health. However, the rise of a "neoliberal" agenda, denigrating the role of government, has once again brought to the fore the importance of prevention and a population health approach to map and publicize the health impacts of this new phase of "global" economic growth.

  13. The AIDS pandemic in historic perspective.

    Kazanjian, Powel

    2014-07-01

    Potent antiretroviral drugs (ART) have changed the nature of AIDS, a once deadly disease, into a manageable illness and offer the promise of reducing the spread of HIV. But the pandemic continues to expand and cause significant morbidity and devastation to families and nations as ART cannot be distributed worldwide to all who need the drugs to treat their infections, prevent HIV transmission, or serve as prophylaxis. Furthermore, conventional behavioral prevention efforts based on theories that individuals can be taught to modify risky behaviors if they have the knowledge to do so have been ineffective. Noting behavioral strategies targeting individuals fail to address broader social and political structures that create environments vulnerable to HIV spread, social scientists and public health officials insist that HIV policies must be comprehensive and also target a variety of structures at the population and environmental level. Nineteenth-century public health programs that targeted environmental susceptibility are the historical analogues to today's comprehensive biomedical and structural strategies to handle AIDS. Current AIDS policies underscore that those fighting HIV using scientific advances in virology and molecular biology cannot isolate HIV from its broader environment and social context any more than their nineteenth-century predecessors who were driven by the filth theory of disease. © The Author 2012.

  14. Heart rate variability - a historical perspective.

    Science.gov (United States)

    Billman, George E

    2011-01-01

    Heart rate variability (HRV), the beat-to-beat variation in either heart rate or the duration of the R-R interval - the heart period, has become a popular clinical and investigational tool. The temporal fluctuations in heart rate exhibit a marked synchrony with respiration (increasing during inspiration and decreasing during expiration - the so called respiratory sinus arrhythmia, RSA) and are widely believed to reflect changes in cardiac autonomic regulation. Although the exact contributions of the parasympathetic and the sympathetic divisions of the autonomic nervous system to this variability are controversial and remain the subject of active investigation and debate, a number of time and frequency domain techniques have been developed to provide insight into cardiac autonomic regulation in both health and disease. It is the purpose of this essay to provide an historical overview of the evolution in the concept of HRV. Briefly, pulse rate was first measured by ancient Greek physicians and scientists. However, it was not until the invention of the "Physician's Pulse Watch" (a watch with a second hand that could be stopped) in 1707 that changes in pulse rate could be accurately assessed. The Rev. Stephen Hales (1733) was the first to note that pulse varied with respiration and in 1847 Carl Ludwig was the first to record RSA. With the measurement of the ECG (1895) and advent of digital signal processing techniques in the 1960s, investigation of HRV and its relationship to health and disease has exploded. This essay will conclude with a brief description of time domain, frequency domain, and non-linear dynamic analysis techniques (and their limitations) that are commonly used to measure HRV.

  16. A historical perspective on ventilator management.

    Shapiro, B A

    1994-02-01

    Paralysis via neuromuscular blockade in ICU patients requires mechanical ventilation. This review historically addresses the technological advances and scientific information upon which ventilatory management concepts are based, with special emphasis on the influence such concepts have had on the use of neuromuscular blocking agents. Specific reference is made to the scientific information and technological advances leading to the newer concepts of ventilatory management. Information from > 100 major studies in the peer-reviewed medical literature, along with the author's 25 yrs of clinical experience and academic involvement in acute respiratory care is presented. Nomenclature related to ventilatory management is specifically defined and consistently utilized to present and interpret the data. Pre-1970 ventilatory management is traced from the clinically unacceptable pressure-limited devices to the reliable performance of volume-limited ventilators. The scientific data and rationale that led to the concept of relatively large tidal volume delivery are reviewed in the light of today's concerns regarding alveolar overdistention, control-mode dyssynchrony, and auto-positive end-expiratory pressure. Also presented are the post-1970 scientific rationales for continuous positive airway pressure/positive end-expiratory pressure therapy, avoidance of alveolar hyperxia, and partial ventilatory support techniques (intermittent mandatory ventilation/synchronized intermittent mandatory ventilation). The development of pressure-support devices is discussed and the capability of pressure-control techniques is presented. The rationale for more recent concepts of total ventilatory support to avoid ventilator-induced lung injury is presented. The traditional techniques utilizing volume-preset ventilators with relatively large tidal volumes remain valid and desirable for the vast majority of patients requiring mechanical ventilation. Neuromuscular blockade is best avoided in these

    I will discuss the evolution of physics education research (PER) within an historical perspective that begins in the 1860s, focuses on developments in the post-World War II period, and extends towards diverse future pathways. PER has incorporated a broad array of themes that resonate with past developments in science education; however, it also provides unique perspectives that offer promise of potential breakthroughs in areas previously underexplored. Nonetheless, there is a long road from promise to realization, and I will try to identify key aspects of past accomplishments as well as of present and future challenges.

    García, P J

    2010-04-01

    In designing an effective national response to sexually transmitted infections (STIs), one must incorporate a historical perspective of previous efforts that have addressed different aspects of STIs. One must understand who have been the key players, what aspects of STIs were the focus of efforts (prevention, treatment or control), and which, if any, societal subgroups were targeted (i.e. sex workers, military, men who have sex with men [MSM], etc.). In addition, one must consider historical and modern attitudes towards sex, sexuality and STIs, especially in terms of taboos and stigmas that may be attached to each. Most importantly, one must recognize which efforts have succeeded, which have failed, and why. This paper presents a historical overview of the perceptions of and responses to STIs at different points in Peru's history, and discusses current efforts to build upon past successes and avoid repeating previous failures that could be helpful for other countries in the Latin American region.

    A brief history of thermal reactor safety in U.S. light water reactors is provided in this paper. Important shortcomings in safety philosophy evolution versus time are identified and potential corrective actions are suggested. It should be recognized, that this analysis represents only one person's opinion and that most historical accountings reflect the author's biases and specific areas of knowledge. In that sense, many of the examples used in this paper are related to heat transfer and fluid flow safety issues, which explains why it has been included in a Thermal Hydraulics session. One additional note of caution: the value of hindsight and the selective nature of human memory when looking at the past cannot be overemphasized in any historical perspective

The aim of this review is to provide a critical and historical perspective, dating back over more than a century, on two competing paradigms. While we understand that this stark dichotomization may be viewed...... as extreme, and is legitimately open to challenge, it is our hope that this didactic approach will serve to stimulate debate. The distinction made focuses on whether the primary etiology involves local causes, such as dental plaque, or involves remote causes, such as nutrition, tobacco use or other systemic...... factors. We provide a brief historical overview of the local and remote cause hypotheses and discuss some key reasons why the local cause hypothesis has become dominant....

    Compared to doctors, patients and institutions, visitors are an understudied constituency in medical history. The collection of essays in this book situates the historical practice of hospital and asylum visiting in broad social, cultural and geographical perspectives. This introduction loosely categorises visitors into four groups: patient visitors, including family and friends; public visitors, such as entertainers, tourists and the clergy, who have no direct formal ties with the institution or the patients; house visitors involved with the management and government of the hospital; and official visitors, who have inspectorial responsibilities. Discussion of the wider historical significance of visiting draws attention to issues such as urban governance, philanthropy, the public sphere, civil society and citizenship.

    History brings together meanings related to earlier periods, being aware of the past as a panorama to reread the present. Madeleine Leininger presented in 1970 an implicit and respectful message to the Nursing Profession when introducing Nursing and Anthropology. Two Worlds to Blend. Implicitly: Nursing you disregard culture. This article shows the absence of the history of anthropology and of nursing within Transcultural Nursing and it includes how education has influenced theoretic, methodological, and comparative approaches giving researchers the responsibility to decide their fundamentals. Berthoud (2001) has inspired the anthropological and historic perspectives of the author, thus universalism, relativism, and comparison are presented.

  7. Clean development mechanism: Perspectives from developing countries

    Energy Technology Data Exchange (ETDEWEB)

    Sari, Agus P.; Meyers, Stephen

    1999-06-01

    This paper addresses the political acceptability and workability of CDM by and in developing countries. At COP-3 in Kyoto in 1997, the general position among developing countries changed from strong rejection of joint implementation to acceptance of CDM. The outgrowth of CDM from a proposal from Brazil to establish a Clean Development Fund gave developing countries a sense of ownership of the idea. More importantly, establishing support for sustainable development as a main goal for CDM overcame the resistance of many developing countries to accept a carbon trading mechanism. The official acceptance of CDM is not a guarantee of continued acceptance, however. Many developing countries expect CDM to facilitate a substantial transfer of technology and other resources to support economic growth. There is concern that Annex I countries may shift official development assistance into CDM in order to gain carbon credits, and that development priorities could suffer as a result. Some fear that private investments could be skewed toward projects that yield carbon credits. Developing country governments are wary regarding the strong role of the private sector envisioned for CDM. Increasing the awareness and capacity of the private sector in developing countries to initiate and implement CDM projects needs to be a high priority. While private sector partnerships will be the main vehicle for resource transfer in CDM, developing country governments want to play a strong role in overseeing and guiding the process so that it best serves their development goals. Most countries feel that establishment of criteria for sustainable development should be left to individual countries. A key issue is how CDM can best support the strengthening of local capacity to sustain and replicate projects that serve both climate change mitigation and sustainable development objectives.There is support among developing countries for commencing CDM as soon as possible. Since official commencement must

    Full Text Available This paper proposes a model of country brand equity that incorporates the issue of sustainability in determining destination brand equity. In particular, the model includes elements of sustainability as its core dimensions and promotes the concept of the country sustainability promise that transforms destination resources into the positive perception and experience. The theoretical model is empirically tested using global secondary data confirming that country image is the most important element followed by sustainability and loyalty. Also, the analysis suggests the existence of the higher order construct confirming the country brand equity concept. Based on the research findings, the article offers some implications to the destination managers by suggesting the direction for further development and strategy implementation.

  9. Separations chemistry for f elements: Recent developments and historical perspective

    With the end of the cold war, the principal mission in actinide separations has changed from production of plutonium to cleanup of the immense volume of moderately radioactive mixed wastes which resulted from fifty years of processing activities. In order to approach the cleanup task from a proper perspective, it is necessary to understand the nature of the problem and how the wastes were generated. In this report, the history of actinide separations, both the basic science and production aspects, is examined. Many of the separations techniques in use today were developed in the 40's and 50's for the identification and production of actinide elements. To respond to the modern world of actinide separations new techniques are being developed for separations ranging from analytical methods to detect ultra-trace concentrations (for bioassay and environmental monitoring) to large scale waste treatment procedures. Some of these new methods are ''improvements'' or adaptations of the historical techniques. Total actinide recovery, lanthanide/actinide separations, and selective partitioning of actinides from inert constituents are of primary concern. This report, offers a historical perspective, review the current status of f element separation processes, and suggest areas for continued research in both actinide separations and waste cleanup/environment remediation

    2003-05-15

    In 1881, President James A. Garfield was shot in the back and died 79 days later. During this time, many controversies arose that had repercussions for years to come. Who was to manage the President's care? A prominent local physician took on the case, but after Garfield's death, he was highly criticized for inappropriate care and for excluding more highly qualified surgeons. Where was the bullet? Multiple opinions were given including that of Alexander Graham Bell. The correct suggestion turned out to be that of a young, unknown assistant demonstrator of anatomy. What was the proper treatment? Local wound care, removal of the bullet, and laparotomy all were considered. Many have felt that the choice of treatment may have proved to be worse than the injury itself. What did the autopsy show? Even this was controversial, with different observers claiming different results. This historical perspective reviews the case as well the controversies that surrounded it.

  11. Historical Background of Inclusive Education Development in the Nordic Countries

    Natalia Andriichuk

    2017-06-01

    Full Text Available The article analyzes and interprets the comprehensive presentation of the development of inclusive education in some Nordic countries, namely Sweden, Norway and Iceland. The article states that the special education is still an alternative form of education for children with special needs who cannot attend secondary schools in the majority of the countries. Thus, the relation between inclusive and special education allows the author to draw some parallels between these two types of study to trace the transition from one to another. The author concludes that the history of inclusive education formation in Sweden, Norway and Iceland has much in common, but the Icelandic education system has characteristics which distinguish it from the two others.

  12. Of Marx and Makers: an Historical Perspective on Generative Justice

    Directory of Open Access Journals (Sweden)

    Ron Eglash

    2016-06-01

    Full Text Available In Marxist frameworks “distributive justice” depends on extracting value through a centralized state. Many new social movements—peer to peer economy, maker activism, community agriculture, queer ecology, etc.—take the opposite approach, keeping value in its unalienated form and allowing it to freely circulate from the bottom up. Unlike Marxism, there is no general theory for bottom-up, unalienated value circulation. This paper examines the concept of “generative justice” through an historical contrast between Marx’s writings and the indigenous cultures that he drew upon. Marx erroneously concluded that while indigenous cultures had unalienated forms of production, only centralized value extraction could allow the productivity needed for a high quality of life. To the contrary, indigenous cultures now provide a robust model for the “gift economy” that underpins open source technological production, agroecology, and restorative approaches to civil rights. Expanding Marx’s concept of unalienated labor value to include unalienated ecological (nonhuman value, as well as the domain of freedom in speech, sexual orientation, spirituality and other forms of “expressive” value, we arrive at an historically informed perspective for generative justice.

    Applications of antimicrobials in food production and human health have found favor throughout human history. Antibiotic applications in agricultural and human medical arenas have resulted in tremendous increases in food animal production and historically unprecedented gains in human health protection. Successes attributed to widespread antibiotic use have been accompanied by the inadvertent emergence of antibiotic-resistant bacteria. A major problem associated with this emerging resistance is the crossover use of some antibiotics in agricultural settings as well as in the prevention and treatment of human disease. This outcome led to calls to restrict the use of human health-related antibiotics in food animal production. Calls for restricted antibiotic use have heightened existing searches for alternatives to antibiotics that give similar or enhanced production qualities as highly reliable as the antibiotics currently provided to food animals. Agricultural and scientific advances, mainly within the last 100 yr, have given us insights into sources, structures, and actions of materials that have found widespread application in our modern world. The purpose of this presentation is to provide a historic perspective on the search for what are generally known as antibiotics and alternative antimicrobials, probiotics, prebiotics, bacteriophages, bacteriocins, and phytotherapeutics.

  14. RACK(1) to the future - a historical perspective

    2013-08-01

    This perspective summarises the first and long overdue RACK1 meeting held at the University of Limerick, Ireland, May 2013, in which RACK1’s role in the immune system, the heart and the brain were discussed and its contribution to disease states such as cancer, cardiac hypertrophy and addiction were described. RACK1 is a scaffolding protein and a member of the WD repeat family of proteins. These proteins have a unique architectural assembly that facilitates protein anchoring and the stabilisation of protein activity. A large body of evidence is accumulating which is helping to define the versatile role of RACK1 in assembling and dismantling complex signaling pathways from the cell membrane to the nucleus in health and disease. In this commentary, we first provide a historical perspective on RACK1. We also address many of the pertinent and topical questions about this protein such as its role in transcription, epigenetics and translation, its cytoskeletal contribution and the merits of targeting RACK1 in disease.

    Full Text Available This paper provides an analysis of the historical evolution of the European welfare state, especially after the second half of the nineteenth century. Even if one considers that social protection systems have their origins in the period of German Chancellor Otto von Bismarck, various social problems have been treated in European countries before the Bismarck’s social legislation, beginning with the sixteenth century. In this article we presented mainly (i the origins of social policy systems in Europe, as shown in the literature covered, (ii the conceptual evolution of the so-called “welfare state” and (iii the development of social security schemes based on International Labour Organization typology.

  16. Camelid Single-Domain Antibodies: Historical Perspective and Future Outlook

    Directory of Open Access Journals (Sweden)

    Mehdi Arbabi-Ghahroudi

    2017-11-01

    Full Text Available Tremendous effort has been expended over the past two and a half decades to understand many aspects of camelid heavy chain antibodies, from their biology, evolution, and immunogenetics to their potential applications in various fields of research and medicine. In this article, I present a historical perspective on the development of camelid single-domain antibodies (sdAbs or VHHs, also widely known as nanobodies since their discovery and discuss the advantages and disadvantages of these unique molecules in various areas of research, industry, and medicine. Commercialization of camelid sdAbs exploded in 2001 with a flurry of patents issued to the Vrije Universiteit Brussel (VUB and later taken on by the Vlaams Interuniversitair Instituut voor Biotechnologie (VIB and, after 2002, the VIB-founded spin-off company, Ablynx. While entrepreneurial spirit has certainly catalyzed the exploration of nanobodies as marketable products, IP restrictions may be partially responsible for the relatively long time span between the discovery of these biomolecules and their entry into the pharmaceutical market. It is now anticipated that the first VHH-based antibody drug, Caplacizumab, a bivalent anti-vWF antibody for treating rare blood clotting disorders, may be approved and commercialized in 2018 or shortly thereafter. This elusive first approval, along with the expiry of key patents, may substantially alter the scientific and biomedical landscape surrounding camelid sdAbs and pave the way for their emergence as mainstream biotherapeutics.

  17. Crisis discussions in psychology--New historical and philosophical perspectives.

    Science.gov (United States)

    Sturm, Thomas; Mülberger, Annette

    2012-06-01

    In this introductory article, we provide a historical and philosophical framework for studying crisis discussions in psychology. We first trace the various meanings of crisis talk outside and inside of the sciences. We then turn to Kuhn's concept of crisis, which is mainly an analyst's category referring to severe clashes between theory and data. His view has also dominated many discussions on the status of psychology: Can it be considered a "mature" science, or are we dealing here with a pre- or multi-paradigmatic discipline? Against these Kuhnian perspectives, we point out that especially, but not only in psychology distinctive crisis declarations and debates have taken place since at least the late 19th century. In these, quite different usages of crisis talk have emerged, which can be determined by looking at (a) the content and (b) the dimensions of the declarations, as well as (c) the functions these declarations had for their authors. Thus, in psychology at least, 'crisis' has been a vigorous actor's category, occasionally having actual effects on the future course of research. While such crisis declarations need not be taken at face value, they nevertheless help to break the spell of Kuhnian analyses of psychology's history. They should inform ways in which the history and philosophy of psychology is studied further. Copyright © 2011 Elsevier Ltd. All rights reserved.

  18. Historical Responsibility for Climate Change - from countries emissions to contribution to temperature increase

    2016-04-01

    The notion of historical responsibility is central to the equity debate and the measure of responsibility as a countries' share of historical global emissions remains one of the essential parameters in so-called equity proposals, which attempt to distribute effort among countries in an equitable manner. The focus of this contribution is on the historical contribution of countries, but it takes it one step further: its general objective lies on estimating countries' contribution directly to the change in climate. The historical responsibility is not based on cumulative emissions but instead measured in terms of the countries' estimated contribution to the increase in global-mean surface-air temperature. This is achieved by (1) compiling a historical emissions dataset for the period from 1850 until 2012 for each individual Kyoto-greenhouse gas and each UNFCCC Party using a consistent methodology and (2) applying those historical emissions to a revised version of the so-called Policy-maker Model put forward by the Ministry of Science and Technology of the Federative Republic of Brazil, which is a simple, yet powerful tool that allows historical GHG emissions of individual countries to be directly related to their effect on global temperature changes. We estimate that the cumulative GHG emissions until 2012 from the USA, the European Union and China contribute to a total temperature increase of about 0.50°C in 2100, which is equivalent to about 50% of the temperature increase from total global GHG emissions by that year (of about 1.0°C). Respectively, the USA, the European Union, and China are responsible for 20.2%, 17.3%, and 12.1% of global temperature increase in 2100. Russian historical emissions are responsible for 0.06°C temperature increase by 2100, ranking as the fourth largest contributor to temperature increase with 6.2% of the total contribution. India ranks fifth: Indian emissions to date would contribute to roughly 0.05°C of global mean temperature

  19. People involved in radiation research and protection - an historical perspective

    2010-01-01

    Full text: The lives of selected people involved in radiation research are covered in two parts: 1. history of radiation and radioactivity; and 2. historical aspects of radiation and radiation protection in Western Australia. History of radiation/radioactivity: The background of some of the key people involved in early radiation research is discussed. These include Rontgen and Becqucrel who undertook early research into X-rays and radioactivity respectively. As well as the radiation hazards which early radiation scientists faced, there were also social pressures, as exemplified by the life of women such as Marie Curie, particularly after the death of her husband Pierre. Despite this being the time of the so-called 'beautiful years' in Europe, where there was a friendly exchange of ideas between scientists from various countries, there were also protracted disagreements. Some of the scientific findings of the Curies' daughter (Irene Joliot-Curie) and husband (Frederic Joliot-Curie) were vigorously disputed by Lisa Meitner (and colleague Otto Hahn) in Vienna. The 'beautiful years' came to an end when politics intruded and scientists such as Lisa Meitner had to flee from persecution. The splitting of the atom and realisation (by Leo Szilard) that a chain reaction was possible, led to political barriers being erected around scientists. With Europe poised for war, the implication of this science for warfare application was cause for concern among many of the normally free thinking and co-operative scientists. Secrecy now prevailed.

  20. Review of retrofit strategies decision system in historic perspective

    Directory of Open Access Journals (Sweden)

    M. D. Bostenaru Dan

    2004-01-01

    Full Text Available Urban development is a process. In structuring and developing its phases different actors are implied, who act under different, sometimes opposite, dynamic conditions and within different reference systems. This paper aims to explore the contribution of participatism to disaster mitigation, when this concerns earthquake impact on urban settlements, through the support provided to multi-criteria decision in matters of retrofit. The research broadness in field of decision making on one side and the lack of a specific model for the retrofit of existing buildings on another side led to an extensive review of the state of the art in related models to address the issue. Core idea in the selection of existing models has been the preoccupation for collaborative issues, in other words, the consideration for the different actors implied in the planning process. The historic perspective on participative planning models is made from the view of two generations of citizen implication. The first approaches focus on the participation of the building owner/inhabitant in the planning process of building construction. As current strategies building rehabilitation and selection from alternative retrofit strategies are presented. New developments include innovative models using the internet or spatial databases. The investigated participation approaches show, that participation and communication as a more comprehensive term are an old topic in the field politics-democratisation-urbanism. In all cases it can be talked of 'successful learning processes', of the improvement of the level of the professional debate. More than 30 years history of participation marked a transition in understanding the concept: from participation, based on a central decision process leading to a solution controlled and steered by the political-administrative system, to communication, characterised by simultaneous decision processes taking place outside politics and administration in co

  1. Prospects for tobacco control in Zimbabwe: a historical perspective.

    Science.gov (United States)

    Woelk, G; Mtisi, S; Vaughan, J P

    2001-09-01

    Using a historical and political economy perspective, this paper explores the prospects for tobacco control in Zimbabwe, the world's sixth largest producer and third largest tobacco exporter. Tobacco production, which first began in the former Rhodesia in the early 1900s, is closely associated with colonial history and land occupation by white settlers. The Zimbabwe (formerly Rhodesia) Tobacco Association was formed in 1928 and soon became a powerful political force. Although land redistribution has always been a central issue, it was not adequately addressed after independence in 1980, largely due to the need for Zimbabwe to gain foreign currency and safeguard employment. However, by the mid-1990s political pressures forced the government to confront the mainly white, commercial farmers with a new land acquisition policy, but intense national and international lobbying prevented its implementation. With advent of global economic changes, and following the start of a structural adjustment programme in 1991, manufacturing began to decline and the government relied even more on the earnings from tobacco exports. Thus strengthening tobacco control policies has always had a low national and public health priority. Recent illegal occupation of predominantly white owned farms, under the guise of implementing the former land redistribution policy, was politically motivated as the government faced its first major challenge at the general elections in June 2000. It remains unclear whether this will lead to long term reductions in tobacco production, although future global declines in demand could weaken the tobacco lobby. However, since Zimbabwe is only a minor consumer of tobacco, a unique opportunity does exist to develop controls on domestic cigarette consumption. To achieve this the isolated ministry of health would need considerable support from international agencies, such as the World Health Organisation and World Bank.

    The study seeks to explore the perception of international patients on Malaysia as a medical tourism destination country, as well as overall patient satisfaction, perceived value and future intention for repeat treatment and services. Self-administered questionnaire was the main method of data collection. The survey covered major private hospitals in medical tourists' states in the country, namely, Penang, Melaka, Selangor and Kuala Lumpur. Convenience sampling was used due to the condition of patients as respondents. Indonesian patients formed the largest majority of international patients in the country. Five dimensions of medical tourism in Malaysia was identified, namely, hospital and staff, country factor, combining tourism and health services, cost saving and insurance and unavailability of treatment. Of these, hospital and staff was found to be the most important factor for the patients. Perception of value, overall satisfaction and intention for future treatment was also found to be high. This indicates that Malaysia is on the right footing in this burgeoning industry. Findings from the study will enable policy-makers to better position Malaysia as a medical tourist destination country. Medical tourism is a recent phenomenon and very little empirical research has been carried out at the patient level. This study is one of the first few studies which seek to explore medical tourism from the perspective of the patients themselves.

    2004-06-01

    This article provides a brief historical perspective on the first scientific research on the greenhouse effect and glaciations. While these two aspects of our climate can be investigated separately, naturalists, physicists and chemists during the 19. century were interested jointly in both issues, as well as the possible relationship between them. The contributions of famous pioneers are mentioned, ranging from scholars with encyclopedic knowledge such as Horace-Benedict de Saussure, to modern scientists like Svante Arrhenius, who was first to predict global warming as a consequence of using fossil fuels. Despite fragmentary observations, these pioneers had prophetic insights. Indeed, the main fundamental concepts used nowadays have been developed during the 19. century. However, we must wait until the second half of the 20. century to see a true revolution of investigative techniques in the Earth Sciences, enabling full access to previously unknown components of the climate system, such as deep oceans and the interior of the polar ice caps.

  8. Health care in Nicaragua: a social and historical perspective.

    Petrack, E M

    1984-10-01

    To facilitate understanding of the advances in health care in Nicaragua since 1979, this discussion examines them within a historical framework. Nicaragua was occupied by US marines almost continuously from 1909-33. In 1933, their withdrawal left in power the US backed National Guard and the 1st dictator, Anastasio Somoza Garcia. Health conditions under the Somoza regime are difficult to evaluate because lack of data and underreporting were the norm. The health care system under Somoza was administered by 23 separate agencies, including the National Social Security Institute (INSS), a national Ministry of Health, independent local health ministries, and autonomous public hospital governing boards. On July 19, 1979, the dictatorship was overthrown in a popular uprising. Somoza left behind a foreign debt of 1.6 billion dollars, which the Sandinista Front for National Liberation (FSLN) needed to honor to qualify for needed loans. Following Somoza's defeat, the new government faced the problem of how to care for the tens of thousands of persons wounded and how to distribute the aid and medical supplies coming in from other countries. The key to achieving these tasks was popular participation and organization. By the early part of 1980, the new government was addressing more directly the organization of the health care system. Unlike the fragmented services under Somoza, health care in the new Nicaragua fell under the control of a unified Ministry of Health (MINSA). In 1980, the FSLN initiated an intensive campaign against illiteracy, 100,000 young Nicaraguans, called "brigadistas," were trained and sent around the country to teach basic reading and writing. In addition, 1 out of 10 was trained in elementary health principles. They were responsible for educating others about hygiene and basic sanitation as well as distributing antimalarial medication. 5 popular Health Campaigns were waged during 1981 against polio; measles, diphtheria, pertussis, and tetanus; rabies

  2. Environmental permits in Arab Gulf countries - local government perspective

    International Nuclear Information System (INIS)

    Kuczynski, L.

    2002-01-01

    The legacy of past environmentally careless oil and gas exploration practices is becoming more apparent as time goes by and our understanding of causes and results increase. In many petroleum producing countries and in Arab Gulf countries in particular, this understanding has resulted in greater social demand for environmental protection and responsible exploitation of limited resources. In response to this demand, governments of the Gulf Region are paying increasingly more attention to the responsible management of environmental impacts of new developments. As a result, most of them require developers to obtain environmental permits supported by a variety of environmental baseline studies, Environmental Impact Assessments and comprehensive Environmental Management Plans. These local environmental requirements are similar to those in North America and Europe, although there are some important differences on account of local environmental, historical and socioeconomic conditions. Developers, who choose to ignore them, often find their projects caught in a web of unfamiliar environmental regulations or administrative procedures that may cause costly and unnecessary delays. Based on the author's Canadian and Arab Gulf regulatory experience, this paper describes some common causes that may delay obtaining environmental permits or cause cancellation of a project, and provides ideas to assist companies in securing necessary permits and licenses.

  3. Virtual water trade and country vulnerability: A network perspective

    Sartori, Martina; Schiavo, Stefano

    2015-04-01

    This work investigates the relationship between countries' participation in virtual water trade and their vulnerability to external shocks from a network perspective. In particular, we investigate whether (i) possible sources of local national crises may interact with the system, propagating through the network and affecting the other countries involved; (ii) the topological characteristics of the international agricultural trade network, translated into virtual water-equivalent flows, may favor countries' vulnerability to external crises. Our work contributes to the debate on the potential merits and risks associated with openness to trade in agricultural and food products. On the one hand, trade helps to ensure that even countries with limited water (and other relevant) resources have access to sufficient food and contribute to the global saving of water. On the other hand, there are fears that openness may increase the vulnerability to external shocks and thus make countries worse off. Here we abstract from political considerations about food sovereignty and independence from imports and focus instead on investigating whether the increased participation in global trade that the world has witnessed in the last 30 years has made the system more susceptible to large shocks. Our analysis reveals that: (i) the probability of larger supply shocks has not increased over time; (ii) the topological characteristics of the VW network are not such as to favor the systemic risk associated with shock propagation; and (iii) higher-order interconnections may reveal further important information about the structure of a network. Regarding the first result, fluctuations in output volumes, among the sources of shock analyzed here, are more likely to generate some instability. The first implication is that, on one side, past national or regional economic crises were not necessarily brought about or strengthened by global trade. The second, more remarkable, implication is that, on

  6. "Fuzziness" in the celular interactome: a historical perspective.

    Science.gov (United States)

    Welch, G Rickey

    2012-01-01

    Some historical background is given for appreciating the impact of the empirical construct known as the cellular protein-protein interactome, which is a seemingly de novo entity that has arisen of late within the context of postgenomic systems biology. The approach here builds on a generalized principle of "fuzziness" in protein behavior, proposed by Tompa and Fuxreiter.(1) Recent controversies in the analysis and interpretation of the interactome studies are rationalized historically under the auspices of this concept. There is an extensive literature on protein-protein interactions, dating to the mid-1900s, which may help clarify the "fuzziness" in the interactome picture and, also, provide a basis for understanding the physiological importance of protein-protein interactions in vivo.

  10. Historical Perspectives and Recent Trends in the Coastal Mozambican Fishery

    Directory of Open Access Journals (Sweden)

    Jessica L. Blythe

    2013-12-01

    Full Text Available Historical data describing changing social-ecological interactions in marine systems can help guide small-scale fisheries management efforts. Fisheries landings data are often the primary source for historical reconstructions of fisheries; however, we argue that reliance on data of a single type and/or from a single scale can lead to potentially misleading conclusions. For example, a narrow focus on aggregate landings statistics can mask processes and trends occurring at local scales, as well as the complex social changes that result from and precipitate marine ecosystem change. Moreover, in the case of many small-scale fisheries, landings statistics are often incomplete and/or inaccurate. We draw on case study research in Mozambique that combines national landings statistics and career history interviews with fish harvesters to generate a multi-scale historical reconstruction that describes social-ecological interactions within the coastal Mozambican fishery. At the national level, our analysis points toward trends of fishing intensification and decline in targeted species, and it highlights the significant impact of small-scale fisheries on marine stocks. At the local level, fishers are experiencing changes in fish abundance and distribution, as well as in their physical, social, and cultural environments, and have responded by increasing their fishing effort. We conclude with a discussion of the governance implications of our methodological approach and findings.

  11. Non-transfusion Dependent Thalassemias: A Developing Country Perspective.

    Science.gov (United States)

    Mukherjee, Somnath; Das, Rashmi R; Raghuwanshi, Babita

    2015-01-01

    Non-transfusion-dependent thalassemias (NTDT) encompass a group of hereditary chronic hemolytic anemia, which, as the name indicates, not require regular blood transfusion for survival. These include β-thalassemia intermedia, hemoglobin E/β-thalassemia, and Hemoglobin H disease (α- thalassemia intermedia). Individuals with structural variant of hemoglobin especially Hemoglobin S and Hemoglobin C associated with "α" or "β" thalassemia in heterozygous condition may also present with similar features of NTDT. NTDT patients are not immune to the development of transfusion unrelated complications in the long run. These hereditary chronic hemolytic anemias are still under-recognized in developing countries like India, where the disease burden might be high causing significant morbidity. The pathophysiologic hallmark that characterizes this group of disorders (ineffective erythropoiesis, hemolysis, chronic anemia) leads to a number of serious complications, similar to transfusion dependent thalassemia. So, timely diagnosis and institution of appropriate preventive/remedial measures as well as education of patient population can help decrease the morbidity to a significant extent. In the present review, focus will be on the pathophysiological mechanisms and available management options of NTDT from a developing country perspective like India.

    1994-09-01

    This paper examines four main themes with respect to some problematic issues concerning the discipline of nursing, nursing scholarship and the social sciences. First, attention is directed to the controversial issues concerning nursing's search for a knowledge base. Second, a historical context is provided by drawing attention to some key developments between the quantitative and qualitative approaches to research in nursing. Third, the issue of the fundamental and attested difficulties in the application of qualitative methodologies is addressed. Finally, it is submitted that in the interest of nursing's future as a scholarly endeavour, the discipline should focus polemic attention on the body of knowledge already accumulated.

    2016-01-01

    This book looks at the types of new research organizations that drive scientific innovation and how ground-breaking science transforms research fields and their organization. Based on historical case studies and comparative empirical data, the book presents new and thought-provoking evidence that improves our knowledge and understanding about how new research fields are formed and how research organizations adapt to breakthroughs in science. While the book is firmly based in science history, it discusses more general sociological and policy propositions regarding scientific innovations and organizational change. The volume brings together leading scholars both from the United States and Europe.

  15. Public and Private Intelligence: Historical and Contemporary Perspectives

    Directory of Open Access Journals (Sweden)

    Ruth Delaforce

    2013-06-01

    Full Text Available Intelligence is often regarded as information that is special or different, which must be safely kept. When sought, collected or used by the private sector, as opposed to public agencies, concerns are raised on the purpose and propriety of such an activity. However, in an historical context, intelligence collection or sharing between public and private interests for the purpose of national security was not unusual, particularly during the Cold War. Case studies from this era indicate that overlapping concerns were economic success combined with political strategy. Glimpses of these shared interests between the state and business can also be identified in the immediate post-Cold War era, and the aftermath of terrorist attacks in 2001. Perhaps the greatest contemporary change is not that “private” and “public” intelligence is shared between business and state, but the extent of such an enterprise. Further issues related to this change are: state dominance in the public-private relationship; potential fragmentation in the intelligence process; gaps in the historical record; and implications for future generations of intelligence professionals.

  16. Bitcoin and Potosí Silver: Historical Perspectives on Cryptocurrency.

    Science.gov (United States)

    Zimmer, Zac

    Bitcoin, the digital cryptocurrency, has been celebrated as the future of money on the Internet. Although Bitcoin does present several forward-looking innovations, it also integrates a very old concept into its digital architecture: the mining of precious metals. Even though Bitcoin explicitly invokes mining as a metaphor and gold as an example for understanding the cryptocurrency, there has been little critical work on the connections between Bitcoin and previous metalist currency regimes. The following essay proposes a historical comparison with colonial South American silver mining and the global currency regime based on the New World silver peso it created as a way to interrogate Bitcoin. The comparison with colonial South America, and specifically the silver mining economy around the Cerro Rico de Potosí, will help to develop a historical and political understanding of Bitcoin's stakes, including questions of resources, labor, energy, and ecology. Mining and the extractive apparatus that accompanies it always imply massive-scale earthworks that reshape the planet itself, a process known as terraforming. The Potosí comparison will reveal Bitcoin to form part of a similar process of digital primitive accumulation we can provisionally name cryptoforming.

  17. A historical perspective on the collaboration between psychoanalysis and neuroscience.

    Sauvagnat, François; Wiss, Matthias; Clément, Sandra

    2010-12-01

    The aim of this article is to present and discuss the connections between psychoanalysis and neuroscience from a historical viewpoint. We start by examining how Sigmund Freud can be viewed as a pioneer in the interaction between these two fields. Freud was himself a neurologist and had maintained an interest in biology as he developed the key concepts of psychoanalysis. His ideas regarding psychosomatics are described. We will also explore how the concept of drive is essential to the connection between psychoanalysis and neuroscience. Then, we describe several key actors and historical events and characters at the interface of these two fields, namely Sándor Radó Lawrence S. Kubie and Mc Culloch, the debates that took place during the Macy conferences, as well as the positions of Jacques Lacan, George L. Engel, and Eric Kandel. Finally, we present a synthesis of the main fields in which the connections between psychoanalysis and neuroscience are already fruitful, and those where they should be developed: the classification of mental diseases, the link between the scientific and psychic dimensions, therapeutics, the organization of the body, intersubjectivity, the subjective division and ambivalence, as well as transferential effects like such as the placebo and nocebo effects. In the conclusion, we advocate several strategic alliances and underscore the complementarity between rigorous scientific experimentation and the individualized psychoanalytic approach.

    The five Arab Gulf countries of Kuwait, Bahrain, Qatar, the United Arab Emirates and Oman possess many shared characteristics and historical ties across their common peninsula. The prime factor uniting them is the historical nature of their entwined involvement with peoples and nations beyond the region. That the Gulf has been an important water passageway since ancient times suggests that the inhabitants of its shores met early on with other civilizations. The knowledge of one's roots, history, and traditional arts supports awareness of inherited culture and can help contextualize and illuminate community reflection and identification. The intricacy of the recording and understanding processes of documentation requires skilled professionals, with knowledge and awareness for the associated tasks. Responsible of cultural heritage should provide the adequate documentations, recording and updating of the records. Collaboration of different individuals such as specialist heritage, archaeologists, surveyors, conservators, researchers, architectural historians, and many other expert personnel is the golden key of successful documentation. The purpose of this document is to show the authorities of Gulf Arab countries and their planning measures, management and sharing effect of recording the cultural heritage. This essay identifies key points in the approach to contextualizing and developing cultural identity in a way that respects organic qualities. Through highlighting a number of archeological ruins and outlining management plans, the essay explores frameworks that can be applied to promote and preserve integral identity of important sites and their greater surrounding communities.

    Among the many historical episodes that have relevance to the establishment of a human base, the voyages of Captain Cook, and the founding of Britain's Botany Bay colony in Australia seems particularly appropriate. The process resulting in the selection of Cook rewards study, as do his relations with the Admiralty, with the scientific establishment and with the scientists who accompanies him. Britain's tight control of the Botany Bay settlement and its unwillingness to promote early self-sufficiency may have delayed the time when Australia became self-supporting. Structuring the lunar base to offer opportunities for private initiatives may hasten the day when it becomes a self-supporting settlement rather than an externally supported scientific base on an Antarctic model

    This review aims to highlight the clinical complexity of chronic subdural hematoma (cSDH) while presenting a brief historical discussion of cSDH. A thorough literature search of published English-language papers was performed in PubMed, Ovid, and Cochrane databases. cSDH affects 1-5.3 per 100,000 individuals annually, with the incidence expected to rise as the U.S. population ages. The symptoms of cSDH are often nonspecific, with headaches being the most common complaint. Other symptoms include weakness, balance and gait problems, and memory problems. A variety of clinical factors must be taken into account in the treatment of cSDH, and the multifaceted treatment paradigms continue to evolve. Copyright © 2017. Published by Elsevier Inc.

  8. The relativity revolution from the perspective of historical epistemology.

    Science.gov (United States)

    Renn, Jürgen

    2004-12-01

    This essay analyzes Einstein's relativity revolution as part of a long-term development of knowledge in which the knowledge system of classical physics was reorganized in a process of reflection, described here as a "Copernican process." This process led in 1905 to the introduction of fundamentally new concepts of space, time, matter, and radiation. On the basis of an extensive historical reconstruction, the heuristics of Einstein's creation of the general theory of relativity, completing the relativity revolution, is interpreted as a further transformation of the knowledge of classical physics, starting from conceiving gravitation as a borderline problem between field theory and mechanics. The essay thus provides an answer to the puzzle of how Einstein was able to create a theory capable of accounting for a wide range of phenomena that were discovered only much later.

    2017-01-01

    Full Text Available Botulinum neurotoxins are diverse proteins. They are currently represented by at least seven serotypes and more than 40 subtypes. New clostridial strains that produce novel neurotoxin variants are being identified with increasing frequency, which presents challenges when organizing the nomenclature surrounding these neurotoxins. Worldwide, researchers are faced with the possibility that toxins having identical sequences may be given different designations or novel toxins having unique sequences may be given the same designations on publication. In order to minimize these problems, an ad hoc committee consisting of over 20 researchers in the field of botulinum neurotoxin research was convened to discuss the clarification of the issues involved in botulinum neurotoxin nomenclature. This publication presents a historical overview of the issues and provides guidelines for botulinum neurotoxin subtype nomenclature in the future.

    Chu, Stephen; Ahmad, Irfan

    2005-10-01

    Ceramics were invented by the Chinese during the T'ang Dynasty, where they quickly became a precious commodity. By the early 18th Century, ceramics found its way into dentistry due to its high strength, biocompatibility, and malleability. Today, ceramic materials are a staple in dentistry, available in both naturally based and partially synthetic formulas. Most recently they have become available as quartz-glass synthetic materials manufactured under controlled conditions to eliminate the inconsistencies and impurities inherent in the naturally based counterpart. This article details the discovery of porcelain and its role as a precious substance throughout the world and time, from its initial use as ornamental earthenware to its practical application in modern dentistry. Upon reading this article, the reader should: Understand the historical significance of porcelain. Recognize the fundamental constituents and physical properties of both natural feldspathic porcelains and fully synthetic ceramics used in dentistry.

    International Nuclear Information System (INIS)

    Pitcher, R.D.; Zar, H.J.

    2008-01-01

    Aim: To determine differences between the plain radiographic features of paediatric pneumocystis pneumonia (PCP) recorded before the emergence of human immunodeficiency virus (HIV) in 1982 and those documented in the HIV era. To establish differences in the radiographic features of PCP documented in HIV-infected children in developed and developing countries. Method: A Medline search of articles was conducted from 1950 to 2006, using the terms 'pneumocystis pneumonia in children' and 'chest radiographic features' or 'bilateral opacification' or 'lobar consolidation' or 'asymmetrical opacification' or 'pneumatocoeles' or 'cavities' or 'pneumothorax' or 'pneumomediastinum' or 'pleural effusion' or 'mediastinal adenopathy' or 'nodules' or 'normal chest radiography'. Appropriate articles were retrieved, radiological data extracted, reference lists examined and hand searches of referenced articles conducted. Results: Diffuse bilateral 'ground-glass' or alveolar pulmonary opacification, which may show some asymmetry, has been consistently documented as the commonest radiographic finding in childhood PCP throughout the period under review. The less common radiological features of PCP in children are similar to those in adults. In developed countries, PCP-related pulmonary air cysts have been reported at an earlier age in HIV-infected children, compared with uninfected children. PCP-related air cysts, pneumothorax, and pneumomediastinum have been reported in children in developed but not in developing countries. Conclusion: The radiological features of paediatric PCP documented before the HIV epidemic are similar to those recorded in the HIV era. Further study of the determinants of the uncommon radiographic features in children is warranted

  16. Systems Approaches: A Global and Historical Perspective on Integrative Medicine

    Science.gov (United States)

    2012-01-01

    The globalization of healing systems is a dance of cultural awareness and cultural dominance that has arisen throughout history. With the development of greater communication and interest in whole-systems approaches to healing, the opportunity for the development of a global perspective on healing has emerged with new life force. The birth of integrative holistic healing systems in the West, such as naturopathic, homeopathic, anthroposophic, integral and functional medicine, and others, echoes the ocean of wisdom present in traditional healing systems, such as traditional Chinese medicine (TCM) and Ayurveda. In working to integrate the lessons from these systems, we see the inextricable link between man and the natural world, we work to understand the root cause of disease, we focus on the whole person to return balance, and we use empiric observation in large populations over time to grasp the interrelationships inherent in the whole-systems view of illness and wellness.

Our perspective draws from three kinds of theory that suggest how...... governmental boundaries have come to be connected in different degrees and in different ways to cultural groups. We use the FICE perspective to integrate the four articles in the focused issue that speak to whether boundaries around countries matter as compared to boundaries around religious groups, within...

    Aim: To determine differences between the plain radiographic features of paediatric pneumocystis pneumonia (PCP) recorded before the emergence of human immunodeficiency virus (HIV) in 1982 and those documented in the HIV era. To establish differences in the radiographic features of PCP documented in HIV-infected children in developed and developing countries. Method: A Medline search of articles was conducted from 1950 to 2006, using the terms 'pneumocystis pneumonia in children' and 'chest radiographic features' or 'bilateral opacification' or 'lobar consolidation' or 'asymmetrical opacification' or 'pneumatocoeles' or 'cavities' or 'pneumothorax' or 'pneumomediastinum' or 'pleural effusion' or 'mediastinal adenopathy' or 'nodules' or 'normal chest radiography'. Appropriate articles were retrieved, radiological data extracted, reference lists examined and hand searches of referenced articles conducted. Results: Diffuse bilateral 'ground-glass' or alveolar pulmonary opacification, which may show some asymmetry, has been consistently documented as the commonest radiographic finding in childhood PCP throughout the period under review. The less common radiological features of PCP in children are similar to those in adults. In developed countries, PCP-related pulmonary air cysts have been reported at an earlier age in HIV-infected children, compared with uninfected children. PCP-related air cysts, pneumothorax, and pneumomediastinum have been reported in children in developed but not in developing countries. Conclusion: The radiological features of paediatric PCP documented before the HIV epidemic are similar to those recorded in the HIV era. Further study of the determinants of the uncommon radiographic features in children is warranted.

  19. Directly smelted lead-tin alloys: A historical perspective

    Dube, R. K.

    2010-08-01

    This paper discusses evidence related to the genesis and occurrence of mixed lead-tin ore deposit consisting of cassiterite and the secondary minerals formed from galena. These evidences belong to a very long time period ranging from pre-historic to as late as the nineteenth century a.d. This type of mixed ore deposits was smelted to prepare lead-tin alloys. The composition of the alloy depended on the composition of the starting ore mixture. A nineteenth century evidence for the production of directly smelted lead-tin alloys in southern Thailand is discussed. A unique and rather uncommon metallurgical terminology in Sanskrit language— Nāgaja—was introduced in India for the tin recovered from impure lead. This suggests that Indians developed a process for recovering tin from lead-tin alloys, which in all probability was based on the general principle of fire refining. It has been shown that in the context of India the possibility of connection between the word Nāgaja and the directly smelted lead-tin alloys cannot be ruled out.

  20. The (deMilitarization of Humanitarian Aid: A Historical Perspective

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Humanitarian workers often complain that international aid to victims of armed conflicts is more and more militarized because relief organizations are embedded into peacekeeping operations, used as a “force multiplier”, or manipulated as an instrument of diplomacy by proxy. Historically, however, charity has always been a military issue in times of war. We can distinguish four types of militarization of relief organizations in this regard. First is the use of charities to make “war by proxy”, as in Afghanistan or Nicaragua in the 1980s. The second pattern is “embedment”, like the Red Cross during the two world wars. The third is “self-defense”, as with the Order of Saint John of Jerusalem (now Malta in the 12th Century. The fourth, finally, is the model of “International Brigades” alongside the Spanish Republicans in 1936 or various liberation movements in the 1970s. In comparison, humanitarian aid today appears to be much less militarized. However, this perception also depends on the various definitions of the word “humanitarian”.

    2001-05-01

    This review provides a perspective on how research on the management of cough has evolved, looks at key methodologic lessons that have been learned from this research and how they may relate to the management of other symptoms, identifies important methodologic challenges that remain to be solved, and lists important questions that still need to be answered. Three important methodologic lessons have been learned. First, cough must be evaluated systematically and according to a neuroanatomic framework. Second, the response to specific therapy must be noted to determine the cause or causes of cough and to characterize the strengths and limitations of diagnostic testing. Third, multiple conditions can simultaneously cause cough. Among the three methodologic challenges that still need to be solved are 1) definitively determining the diagnostic accuracy and reliability of 24-hour esophageal pH monitoring and how best to interpret pH test results, 2) definitively determining the role of nonacid reflux in cough due to gastroesophageal reflux disease, and 3) developing reliable and reproducible subjective and objective methods with which to assess the efficacy of cough therapy. Numerous important clinical questions are still unanswered: What role do empirical therapeutic trials play in diagnosing the cause of chronic cough? What is the most cost-effective approach to the diagnosis and treatment of chronic cough: empirical therapeutic trials or laboratory testing-directed therapeutic trials? How often is environmental air pollution, unrelated to allergies or smoking, responsible for chronic cough?

    With the end of the cold war, the principal mission in actinide separations has changed from production of plutonium to cleanup of the immense volume of moderately radioactive mixed wastes which resulted from fifty years of processing activities. In order to approach the cleanup task from a proper perspective, it is necessary to understand how the wastes were generated. Most of the key separations techniques central to actinide production were developed in the 40's and 50's for the identification and production of actinide elements. Total actinide recovery, lanthanide/actinide separations, and selective partitioning of actinides from inert constituents are currently of primary concern. To respond to the modern world of actinide separations, new techniques are being developed for separations ranging from analytical methods to detect ultra-trace concentrations (for bioassay and environmental monitoring) to large-scale waste treatment procedures. In this report, the history of actinide separations, both the basic science and production aspects, is examined and evaluated in terms of contemporary priorities

    Full Text Available The concept of caring in nursing has changed throughout the years. Nursing has developed to meet the needs of the population and to adapt at the same time to scientific knowledge, which has taken another dimension, and technical demand. Every field in nursing gains new formas as it evolves, namely the mental health and psychiatric fields. We start by describing the dominant beliefs of society in the past regarding mental health. We will then talk about mental patients in Portugal from the 16th Century on (1539-1850 and how they were cared for, underlining the first psychiatric institution - Rilhafoles Hospital. We will elaborate on the more common treatments in psychiatry, the purposes they served and how the nursing staff intervened in their application. Finally, we will put the evolution of nursing care to the mental patients into perspective, from the begining of the 20th century, as well as the development of nursing schools in the field of mental and psychiatric health.

    The capacity for specialization and radiation make fish an excellent group in which to investigate the depth and variety of animal cognition. Even though early observations of fish using tools predates the discovery of tool use in chimpanzees, fish cognition has historically been somewhat overlooked. However, a recent surge of interest is now providing a wealth of material on which to draw examples, and this has required a selective approach to choosing the research described below. Our goal is to illustrate the necessity for basing cognitive investigations on the ecological and evolutionary context of the species at hand. We also seek to illustrate the importance of ecology and the environment in honing a range of sensory systems that allow fish to glean information and support informed decision-making. The various environments and challenges with which fish interact require equally varied cognitive skills, and the solutions that fish have developed are truly impressive. Similarly, we illustrate how common ecological problems will frequently produce common cognitive solutions. Below, we focus on four topics: spatial learning and memory, avoiding predators and catching prey, communication, and innovation. These are used to illustrate how both simple and sophisticated cognitive processes underpin much of the adaptive behavioral flexibility exhibited throughout fish phylogeny. Never before has the field had such a wide array of interdisciplinary techniques available to access both cognitive and mechanistic processes underpinning fish behavior. This capacity comes at a critical time to predict and manage fish populations in an era of unprecedented global change. © 2015 John Wiley & Sons, Ltd.

    Swimming, which is the coordinated and harmonic movement of the human body inside a liquid medium by means of the combined action of the superior and inferior limbs, is a physical activity which is diffused throughout the whole world and it is practiced by healthy and non-healthy subjects. Swimming is one of the physical activities with less contraindications and, with limited exceptions, can be suggested to individuals of both sexes and of every age range, including the most advanced. Swimming requires energy both for the floating process and for the anterograde progression, with a different and variable osteo-arthro-muscular involvement according to the different styles. The energetic requirement is about four times that for running, with an overall efficiency inferior to 10%; the energetic cost of swimming in the female subject is approximately two thirds of that in the male subject. The moderate aerobic training typical of swimming is useful for diabetic and hypertensive individuals, for people with painful conditions of rachis, as also for obese and orthopaedic patients. Motor activity inside the water reduces the risk of muscular-tendinous lesions and, without loading the joints in excess, requires the harmonic activation of the whole human musculature. Swimming is an activity requiring multiple abilities, ranging from a sense of equilibrium to that of rhythm, from reaction speed to velocity, from joint mobility to resistance. The structured interest for swimming in the perspective of human health from the beginning of civilization, as described in this contribution, underlines the relevance attributed to this activity in the course of human history.

    Full Text Available The Nigerian economy started experiencing economic recession from 1981 which was characterized by low capacity utilization, incomes, and consumption patterns. Public enterprises were operating at the lowest ebb. Government discovered that, without any exception, such enterprises were infested with problems of confused and conflicting missions; political interference in operating decisions; abuse of monopoly powers; defective capital structures; bureaucratic redtapism in their relations with supervisory agencies; mismanagement; nepotism and corruption. Consequently, reform failures and entrenched bureaucratic corruption have created systemic poverty amidst robust economic growth in Nigeria; a situation that supports the phenomenon of poor people in a rich country. Nigeria at present is ranked among the poorest nations in the world and also has one of the highest unemployment rates. It is estimated that more than one in every five adults in Nigeria is either unemployed or underemployed with about 67 million youths unemployed which is not unrelated to the effects of mismanagement and reform failures. The exploratory research design was used in the study. Qualitative data provided empirical evidence that most past reform programmes in Nigeria did not achieve the objectives for which they were established. With a Negative – Positive Ratio of 7:2 based on the study, it was found that government reform policies have not made the desired positive impact on socio-economic development in Nigeria.

  8. Future potential country doctor: the perspectives of German GPs.

    There is a shortage of general practitioners (GPs) in many countries, especially in rural areas. There are several reasons for this shortage. Over the last decade, fewer medical students in Germany have decided to work in patient care, even fewer in general practice and fewer still in general practice in rural areas. The aim of this study was to explore the 'pros and cons' of GPs' work in rural areas and to identify from GPs' perspective possible measures for counteracting future GP shortages. Within a qualitative approach, 16 semi-structured interviews were conducted with GPs. Data analysis was carried out using qualitative content analysis. The results were categorized into three main inductively-derived categories: personal, professional and regional/structural level. A higher level of self-confidence and a higher 'feel-good' factor due to GPs originating from rural areas were positive aspects at the personal level. Regarding the professional level, a low level of competition and varied work made a GP's profession attractive in rural areas. Negative aspects were mostly apparent at the regional/structural level, such a low earnings and few leisure facilities. Measures to counter the lack of GPs in rural areas were explored on all three levels: on the personal level, more optimism and resulting satisfaction on the part of doctors in rural areas could be improved by enhancing the benefits of being a doctor in a rural area. Regarding the professional level, more group practices are required to make working as a GP in a rural area more attractive. At a regional/structural level, young physicians who originate from rural areas should be recruited to work in rural areas. Financial incentives are regarded as not sufficient to attract enough young physicians to open practices in rural areas. Future action will be required at the personal, professional and regional/structural levels. The origin of medical students (urban or rural) should be considered a relevant

    Osprey (Pandion haliaetus) populations were adversely affected by DDT and perhaps other contaminants in the United States and elsewhere. Reduced productivity, eggshell thinning, and high DDE concentrations in eggs were the signs associated with declining osprey populations in the 1950s, 1960s, and 1970s. The species was one of the first studied on a large scale to bring contaminant issues into focus. Although few quantitative population data were available prior to the 1960s, many osprey populations in North America were studied during the 1960s and 1970s with much learned about basic life history and biology. This article reviews the historical and current effects of contaminants on regional osprey populations. Breeding populations in many regions of North America showed post-DDT-era (1972) population increases of varying magnitudes, with many populations now appearing to stabilize at much higher numbers than initially reported in the 1970s and 1980s. However, the magnitude of regional population increases in the United States between 1981 (first Nationwide Survey, ∼8,000 pairs), when some recovery had already occurred, 1994 (second survey, ∼14,200), and 2001 (third survey, ∼16,000–19,000), or any other years, is likely not a simple response to the release from earlier contaminant effects, but a response to multi-factorial effects. This indirect “contaminant effects” measurement comparing changes (i.e., recovery) in post-DDT-era population numbers over time is probably confounded by changing human attitudes toward birds of prey (shooting, destroying nests, etc.), changing habitats, changing fish populations, and perhaps competition from other species. The species' adaptation to newly created reservoirs and its increasing use of artificial nesting structures (power poles, nesting platforms, cell towers, channel markers, offshore duck blinds, etc.) are two important factors. The timing of the initial use of artificial nesting structures, which replaced

    Droughts are natural phenomenon experienced by all nations across the globe. Drought inherently means a scarcity of water, which adversely affects various sectors of human socio-economic spectrum, e.g. agriculture, hydropower generation, water supply, industry, recreation, navigation, fish production etc. The prime cause of droughts is the occurrence of less than optimal (below normal) precipitation, which has its origin to various natural reasons, the most important being the global climatic forcing. Droughts are also referred to as sustained and regionally extensive occurrences of below average water availability which invariably cultivate into environmental disasters. The evolution of a drought event is defined into four types; meteorological, agricultural, hydrological, and socio-economic. Drought affects all aspects of societal systems irrespective of how it is defined. This has led to a wide range of studies conducted by meteorologists, ecologists, environmentalists, hydrologists, geologists and agricultural scientists in attempts to understand drought processes as required to analyze and predict the impacts of droughts. A conceptual definition, such as a shortage of water relied on by human activity, avoids quantification of a drought event. On the other hand, the purpose of an operational definition is to determine the beginning, termination, and severity of a drought event. The severity assessment of droughts is of primary importance for allocation and management of available water resources. The progression and impact of historical droughts in a region is helpful for developing relationships and techniques to investigate relevant characteristics of droughts. For optimum drought preparedness and mitigative responses, professional bodies need to provide information to private and government agencies in a manner that may also be understood by their employers, stakeholders and the general public. Drought indicators bridge this communication gap between all

  12. Woodland caribou management in Alberta: historical perspectives and future opportunities

    Directory of Open Access Journals (Sweden)

    2007-04-01

    Full Text Available Woodland caribou conservation has been the topic of much debate for the past few decades. By the late 1970s there was growing concern about declining woodland caribou populations and the interaction between industrial activities and woodland caribou. Initial concerns led to the closure of the licensed hunting season in 1981. Early confrontation between government and industry in the late 1980s transformed into a series of evolving collaborative ventures. Improving our understanding of the basic ecology of woodland caribou in Alberta was at the center of early research efforts; more recent studies have examined the effects of industrial activities on caribou and effectiveness of various mitigation factors. Despite having amassed an impressive body of information from a research and monitoring perspective, progress on implementing effective management actions has been less dramatic. Industry has endured significant costs implementing a variety of perceived conservation initiatives, but caribou populations continued to decline through the last few decades. While some parties feel more research is needed, there is growing consensus that changes to habitat as induced by human activities are important factors influencing current caribou declines. Predation is a proximate cause of most caribou mortality. Climate change mediated alterations to habitat and predator-prey interactions remain a key source of uncertainty relative to future caribou population trends. Management actions will need to deal with long term habitat changes associated with human land use and short term implications of increased predation. In 2005, the provincial minister responsible for caribou conservation responded to the draft 2004 recovery plan and created the Alberta Caribou Committee (ACC. The goal of the ACC is to maintain and recover woodland caribou in Alberta’s forest ecosystems while providing opportunities for resource development, following guidance provided by the

    Full Text Available Afrocentricity seems to be emerging as one of the potent critical tools that could be used to re-establish and qualify African cultural identity through literary study among others. The primary objective of this movement is to reinterpret world history from an African perspective. This article will therefore examine some historical features of S.M. Guma’s novels from the 1960s to the 1990s from an African perspective. By applying the Afrocentric paradigm this will attempt to demonstrate how material conditions of the period have provided useful raw materials for the Sesotho historical novel, which tends to illuminate a better understanding of the Basotho culture, history, identity and nationhood.

    Full Text Available Through the use of a historical perspective, the aim of this article is to discuss and clarify the concurrent and conflicting interests and norms that have characterized the establishment and development of important institutions in Norwegian working life. The article concentrates on collective bargaining systems, the arrangements for codetermination, and the working environment regulations in both the public and private sector, which are regarded as the main institutions in the Norwegian and Nordic models of working life relations. The article is structured by an analytical distinction between three different historical periods that have constituted three distinct versions of the Norwegian model. By presenting a historical synthesis of Norwegian experiences, the article is a contribution to the ongoing debate on the varieties in the Nordic model, as to further comparisons and broader transnational studies.

  17. Perspective has a strong effect on the calculation of historical contributions to global warming

    The politically contentious issue of calculating countries’ contributions to climate change is strongly dependent on methodological choices. Different principles can be applied for distributing efforts for reducing human-induced global warming. According to the ‘Brazilian Proposal’, industrialized countries would reduce emissions proportional to their historical contributions to warming. This proposal was based on the assumption that the political process would lead to a global top-down agreement. The Paris Agreement changed the role of historical responsibilities. Whereas the agreement refers to equity principles, differentiation of mitigation efforts is delegated to each country, as countries will submit new national contributions every five years without any international negotiation. It is likely that considerations of historical contributions and distributive fairness will continue to play a key role, but increasingly so in a national setting. Contributions to warming can be used as a background for negotiations to inform and justify positions, and may also be useful for countries’ own assessment of what constitutes reasonable and fair contributions to limiting warming. Despite the fact that the decision from COP21 explicitly rules out compensation in the context of loss and damage, it is likely that considerations of historical responsibility will also play a role in future discussions. However, methodological choices have substantial impacts on calculated contributions to warming, including rank-ordering of contributions, and thus support the view that there is no single correct answer to the question of how much each country has contributed. There are fundamental value-related and ethical questions that cannot be answered through a single set of calculated contributions. Thus, analyses of historical contributions should not present just one set of results, but rather present a spectrum of results showing how the calculated contributions vary with a

    The nuclear technology base in a developing country is relatively much smaller compared to those in the industrialised countries. Thus, nuclear knowledge and its management are of great importance for those countries which are interested in nuclear technology but are still in the development phase. It is neither desirable nor possible to use imported nuclear technology as a black box. It is important for a developing country to acquire the ability for the safe and efficient operation of a nuclear facility such as a nuclear power plant. This should be done with maximum local participation and a sound institutional memory. (author)

    We will discuss the current state of R&D in the fields of condensed matter, novel materials, and nanotechnology in the Andean nations. We will initially consider Latin America and the Caribbean (LAC) to then visualize individual developments, as well as those for the region as a whole in these fields of knowledge in each of the nations constituting the Andean Region (Bolivia, Ecuador, Chile, Venezuela, Peru, and Colombia). Based on Science & Technology watch exercises in the countries involved, along with the Iberian American and Inter-American Science & Technology Network of Indicators (Red de indicadores de Ciencia y Tecnolog'ia (RICYT) iberoamericana e interamericana)1, we will reveal statistical data that will shed light on the development in the fields mentioned. As will be noted, total R&D investment in Latin American and Caribbean countries remained constant since 1997. In spite of having reached a general increase in publications without international collaboration in LAC nations, the countries with greatest research productivity in Latin America (Argentina, Mexico, Brazil, and Chile) have strengthened their international collaboration with the United States, France, Germany, and Italy through close links associated with the formation processes of their researchers. Academic and research integration is evaluated through joint authorship of scientific articles, evidencing close collaboration in fields of research. This principle has been used in the creation of cooperation networks among participating nations. As far as networks of research on condensed matter, novel materials, and nanotechnology, the Andean nations have not consolidated a regional network allowing permanent and effective cooperation in research and technological development; as would be expected, given their idiomatic and cultural similarities, their historical background, and geographical proximity, which have been integrating factors in other research areas or socio-economic aspects.

    Full Text Available Comparison of levels of development among countries is usually done by reducing values in national currencies with a common denominator, using the official exchange rate. Because of its unreality, the values calculated in this way do not illustrate real relations between compared countries. That brings about the launching of the UN International Comparison Project (latter Programme with two fold aims: developing a method for international comparison of real domestic product which could be applied to a number of very heterogeneous countries, and the comparison of growing number of very different countries. Until now six phases of comparisons are finished. Taking into consideration problems that appeared in the realization of the VI ICP phase as well as quality improvement proposals, a decision has been made to launch a new, global round for 2003-2006. Comparison will cover 150 countries (the widest coverage ever. This will give global character to the comparison, which was the end cause of the ICP.

    To gain a historical and comparative perspective about the future of ophthalmology within the profession of medicine. A literature search is made of disciplines other than medicine (history, sociology, philosophy, economics, and ethics) in order to assess factors responsible for survival and healthiness of a profession. The "learned" professions (medicine, law, and theology) are assessed. Other "professional" careers valued by society (sports and classical music) are reviewed. From the perspective of other disciplines, the future of ophthalmology is seen as vulnerable and fragile. Survival of professions, be they classically or economically defined, is linked to societal needs, a profession's unique commitment and ability to provide services to society, and the profession's maintenance of knowledge as well as skill-based services. Historical evidence has shown erosion of a profession's power consequent to capitalist influences, government influences, access of skills by less trained individuals, and elitist posturing by a profession. Comparative evidence has shown societal acceptance of an escalation of salaries for designated superstars, increasing roles and influence of managerial personnel, and trivialization of values other than economic ones. Attention to historical and comparative trends by individual ophthalmologists as well as associations representing ophthalmologists is mandatory if ophthalmology as we know it is to survive within the profession of medicine.

  3. Clarifying appeals to dignity in medical ethics from an historical perspective.

    2009-03-01

    Over the past few decades the concept of (human) dignity has deeply pervaded medical ethics. Appeals to dignity, however, are often unclear. As a result some prefer to eliminate the concept from medical ethics, whereas others try to render it useful in this context. We think that appeals to dignity in medical ethics can be clarified by considering the concept from an historical perspective. Firstly, on the basis of historical texts we propose a framework for defining the concept in medical debates. The framework shows that dignity can occur in a relational, an unconditional, a subjective and a Kantian form. Interestingly, all forms relate to one concept since they have four features in common: dignity refers, in a restricted sense, to the 'special status of human beings'; it is based on essential human characteristics; the subject of dignity should live up to it; and it is a vulnerable concept, it can be lost or violated. We argue that being explicit about the meaning of dignity will prevent dignity from becoming a conversation-stopper in moral debate. Secondly, an historical perspective on dignity shows that it is not yet time to dispose of dignity in medical ethics. At least Kantian and relational dignity can be made useful in medical ethics.

    Lack of government intervention in South Africa’s mining industry has worsened conflicts associated with limited water resources. With the advent of democracy, new legislation demands that all South African citizens have the right to a clean, safe environment, including access to potable water, and that the country develop in a sustainable manner. But conflict remains due to the historical partnership between the government and the mining industry, as well as due to cumulative impacts associa...

  7. The Role of Historical Resource Constraints in Modern Gender Inequality: A Cross-Country Analysis

    OpenAIRE

    Hazarika, Gautam; Jha, Chandan Kumar; Sarangi, Sudipta

    2014-01-01

    We posit that historical resource scarcities played a role in the emergence of gender norms inimical to women that persist to this day. This thesis is supported by our finding that nations’ historical resource endowments, as measured by the historical availability of arable land, are statistically significantly negatively related to their present levels of gender inequality, as gauged by the United Nations Development Programme’s Gender Inequality Index.

    2016-01-01

    This book focuses on the advances in transtibial prosthetic technology and targets research in the evolution of the powered prosthesis such as the BiOM, which was derived from considerable research and development at the Massachusetts Institute of Technology. The concept of the book spans the historical evolution of prosthetic applications from passive to new and futuristic robotic prosthetic technologies.  The author describes the reasons for amputation, surgical procedures, and an historical perspective of the prosthesis for the lower limb. He also addresses the phases and sub-phases of gait and compensatory mechanisms arising for a transtibial prosthesis and links the compensatory mechanisms to long-term morbidities.  The general technologies for gait analysis central to prosthetic design and the inherent biomechanics foundations for analysis are also explored.  The book reports on recent-past to current-term applications with passive elastic prostheses.  The core of the book deals with futuristic robo...

  9. Historical perspective and contemporary management of acute coronary syndromes: from MONA to THROMBINS2.

    Kline, Kristopher P; Conti, C Richard; Winchester, David E

    2015-01-01

    Acute coronary syndrome (ACS) remains a major burden on morbidity and mortality in the United States. Medical professionals and students often use the mnemonic 'MONA' (morphine, oxygen, nitroglycerin and aspirin) to recall treatments for ACS; however, this list of therapies is outdated. We provide a historical perspective on 'MONA,' attempt to uncover its origin in the medical literature, and demonstrate the myriad changes that have occurred over the last 50 years of ACS management. We have developed a novel mnemonic, 'THROMBINS2' (thienopyridines, heparin/enoxaparin, renin-angiotensin system blockers, oxygen, morphine, beta blocker, intervention, nitroglycerin, statin/salicylate) to help bedside clinicians recall all the elements of contemporary ACS management. We demonstrate the mortality benefit for each component of contemporary ACS management, correlating the continued improvement with historical data on mortality after myocardial infarction. We encourage providers to utilize this mnemonic to explore options and guide treatments in ACS patients.

  10. Arts and ageing; life expectancy of historical artists in the Low Countries.

    Directory of Open Access Journals (Sweden)

    Fereshta Mirzada

    Full Text Available Practising arts has been linked to lowering stress, anxiety and blood pressure. These mechanisms are all known to affect the ageing process. Therefore, we examine the relation between long-term involvement in arts and life expectancy at age 50 (LE50, in a cohort of 12,159 male acoustic, literary and visual artists, who were born between 1700 and 1899 in the Low Countries. We compared the life expectancy at age 50 of the various artists with the elite and middle class of that time. In the birth cohorts before 1850, acoustic (LE50:14.5-19.5 and literary artists (LE50:17.8-20.8 had a similar life expectancy at age 50 compared to the elite (LE50:18.0-19.0. Only visual artists (LE50:15.5-17.1 had a lower life expectancy at age 50 compared to the elite at that time. For the most recent birth cohorts from 1850 through 1899, the comparison between artists and the elite reversed and acoustic and literary artist had a lower life expectancy at age 50, while visual artists enjoyed a similar life expectancy at age 50. Although artists belonged to the middle socioeconomic class and lived predominantly in urban areas with poor living conditions, they had a life expectancy similar to the elite population. This is in line with observed favourable effects of practicing arts on health in the short-term. From our historical analysis, we hypothesize several mechanisms through which artistic creativity could influence the ageing process and life expectancy. These hypotheses, however, should be formally tested before any definite conclusions on effects of arts on ageing can be drawn.

  11. Propulsion Control Technology Development in the United States A Historical Perspective

    Jaw, Link C.a; Garg, Sanjay

    2005-01-01

    This paper presents a historical perspective of the advancement of control technologies for aircraft gas turbine engines. The paper primarily covers technology advances in the United States in the last 60 years (1940 to approximately 2002). The paper emphasizes the pioneering technologies that have been tested or implemented during this period, assimilating knowledge and experience from industry experts, including personal interviews with both current and retired experts. Since the first United States-built aircraft gas turbine engine was flown in 1942, engine control technology has evolved from a simple hydro-mechanical fuel metering valve to a full-authority digital electronic control system (FADEC) that is common to all modern aircraft propulsion systems. At the same time, control systems have provided engine diagnostic functions. Engine diagnostic capabilities have also evolved from pilot observation of engine gauges to the automated on-board diagnostic system that uses mathematical models to assess engine health and assist in post-flight troubleshooting and maintenance. Using system complexity and capability as a measure, we can break the historical development of control systems down to four phases: (1) the start-up phase (1942 to 1949), (2) the growth phase (1950 to 1969), (3) the electronic phase (1970 to 1989), and (4) the integration phase (1990 to 2002). In each phase, the state-of-the-art control technology is described and the engines that have become historical landmarks, from the control and diagnostic standpoint, are identified. Finally, a historical perspective of engine controls in the last 60 years is presented in terms of control system complexity, number of sensors, number of lines of software (or embedded code), and other factors.

Women dedicated to the professional care have always existed, also to the unpaid home care of the sick, elderly, with some disability, and children. This study has been carried out a historical and current verification of this question, marking its most characteristic and significant features. From that perspective, we tried to answer these key questions: causes that have motivated this fact, its social consequences and, finally, the most important future implications for all, men and women that, surely, we will be caregivers and strapped for care in our illness.

    technical and sociological reasons. The Mountain lands' conservation and restoration law of 1882 aimed to better fit local issues. The idea of the presentation is thus to highlight how evolved the historical comprehension of torrential hazards and of the usefulness of check dams in mitigation plans in a changing environment on the technical as well as on the sociological and regulatory points of view. Pioneering scientific and technical works on torrential hydraulics and check dams will be presented. Describing the global context that leads to French laws of 1860,1864 and 1882 will allow us to explain the extensive development of the works in more than a thousand of torrents and a hundred of big landslides. We then will discuss the evolution of technics during the beginning of the 20th century and the changes induced after WWII by the arrival of reinforced-concrete technics. We will conclude the presentation with a synthesis table aiming to highlight the different functions of check dams based on a description of their situations in the watershed, compare to other structures' situations and on shape criteria. This historical perspective will hopefully help people to better understand for which purposes some structures have been built in the past centuries and what lessons can be learnt from this assessment.

    2016-12-01

    Full Text Available In this article, we investigate how entrepreneurial intentions of individuals in the eight countries of the Danube region are shaped by different components of individuals’ personal attitudes, the subjective norm and personal behavioral control. We analyze the internal structure of these components as well as some demographic and human capital factors. Cultural and developmental differences influencing variation in causal effects among variables in the model are analyzed. Structural equation modeling is used for data obtained by adult population surveys within the GEM research. Results of our study show that the entrepreneurial intention model is applicable across countries and that the internal effects among components of motivational antecedents exist, although not all hypothesized relationships are confirmed. Our study suggests that the process from perception to intention is similarly shaped across the eight countries of the Danube region, although there are several differences in the magnitude of causal effects as well as differences regarding influential factors.

    De Simone, Gustavo G

    2003-01-01

    Argentina is a large South American country with a high prevalence of chronic disease-related mortality and a clear need for implementation of palliative care. Primary concerns related to palliative care are cultural, socio-economic and educational. Increasing poverty, patients and families receiving inadequate information about their diagnosis or prognosis, drug availability and costs, and insufficient knowledge by health care providers are obstacles to palliative care. Palliative care programs are developing throughout the country and methods by which they are meeting their needs are described. Several Argentinean palliative care initiatives are described and the role of the Pallium Latinomérica training program is discussed.

  17. Perspectives on climate change and adaptation funding in developing countries

    Directory of Open Access Journals (Sweden)

    P Lalthapersad-Pillay

    2011-12-01

    Full Text Available Most studies concur that climate change could seriously affect the sustainability and well-being of developing countries as they depend directly on climate-sensitive natural resources for their livelihood endeavours. This could primarily occur through reduced agricultural productivity, a higher incidence of diseases, the displacement of people, loss of livelihood and food price increases, all of which could contribute to food insecurity, malnourishment and escalating poverty. Although developing countries have contributed the least to Green house Gas (GHG emissions, they stand to lose the most and it is likely that many of the development gains that have been made thus far will be reversed. To ensure that poverty reduction and economic growth do not become elusive goals for developing countries, it will be necessary to provide funds for potential adaptation measures to prevent these countries slipping further down the Human Development Index (HDI ranking. In this paper, we will use Africa as a reference and look at the funds required for adaptation, the possible sources of funds and the conflict that may occur in prioritizing development objectives.

  18. Information-Driven Safeguards: A Country Officer's Perspective

    Gyane, E.

    2010-01-01

    Since the transition from 'traditional' to strengthened safeguards, the evaluation and analysis of information has played an increasingly important role in the Agency's safeguards activities. During the State evaluation process, the Agency utilizes all available information for drawing credible safeguards conclusions. Besides State declared information and data gathered during inspections, a large number of information sources are reviewed for any indications of safeguards relevance. The State level approach - in contrast to the facility-based approach under traditional safeguards - considers the acquisition paths available to a State and adjusts safeguards intensity accordingly. An additional protocol widens the information base available to the Agency for analysis and evaluation and it extends the Agency's access rights in the field. The use of information for determining safeguards activities is often referred to as 'information-driven safeguards'. Country officers are inspectors in the Department of Safeguards Operations Divisions who are responsible for States and thus form the base of the Agency's information chain. The information-driven safeguards approach has led to a significant change in the role of inspector country officers: While the verification of declared nuclear material remains the cornerstone of the IAEA Safeguards System, country officers are now not only expected to be knowledgeable about the inspection-related aspects in their countries. They also need to act on information on their States coming from a variety of sources on an ongoing basis, in order to identify proliferation indicators at an early stage. Country officers thus analyse developments in their States as well as their States' relations with other States. They review scientific literature for research that could potentially be of safeguards relevance. They observe their States' nuclear facilities from satellite imagery. They evaluate reports on nuclear trade between their States

    2018-04-01

    Full Text Available In the studies about adolescence, it is noticeable that psychology has more and more been invited to give answers to questions pertaining this specific period of the human development. The historical-cultural perspective proposed by Lev Semenovich Vygotsky and his followers has represented an important theoretical approach to the comprehension of the human being. Thus, this study aims to offer contributions to the debate about adolescence as a social category and a particular stage of the cultural development of subjects. In this way, the main ideas of this Russian theorist are presented here, incorporating them into the discussion that is still incipient in the studies of the historical-cultural perspective: the role of the body in the constitution of subjects. With this starting point, we build arguments that reinforce the monolithic characteristic of the constitution of the human being, where the mind and the body are inseparable parts of the same gear, that develop together along the lifespan, through the social relations of the individuals with the environmental elements. As final considerations, it is pointed out that the role of the body in the process of developing a conceptual thought – a specific characteristic of adolescence – cannot be neglected when we propose the goal to understand the constitution of the totality of the human psyche.

    Prophylactic antibiotics in acute necrotizing pancreatitis is controversial. The mortality of acute necrotizing pancreatitis is 8-25% in the western world. In view of the limited resources available for managing the complications of infected pancreatitis in developing countries, the use of prophylactic antibiotics may be recommended in selected cases. Various antibiotics show good penetration into the pancreatic tissue; imipenem and quinolones have better penetration. Clinical trials on the use of prophylactic antibiotics in necrotizing pancreatitis have been reviewed. Prophylactic antibiotics have been considered if greater than 30% pancreatic necrosis as documented by CT scan. Imipenem can be given for a duration of 10 to 14 days if no systemic complications are present. In a developing country where the cost of managing complications of pancreatitis can be a limiting factor for patients, the use of prophylactic antibiotics early on in the disease in selected cases can be beneficial.

    Bhattacharyya, S.C.

    1997-01-01

    Economists prefer to monitor environmental protection and sustainable development through the use o economic instruments rather than with 'command and control' mechanisms. Energy, taxes and subsidies have emerged as a standard prescription for internalizing externalities. Yet existing energy tax policies, both in developed and developing countries, show, considerable contradictions in terms of environmental considerations. The question needs to be asked why this is so. Moreover, the suitability of fiscal measures for internalizing negative externalities in developing countries needs to be questioned. The objective of this article is to reveal the inherent contradictions and ambiguities in the application of taxes or subsidies to satisfy multiple objectives. It is argued that economic theory does not provide any ready-made solution to the problem and often sociopolitical considerations determine the outcome. Similarly, certain characteristics of developing countries, such as the existence of an important informal sector and the extensive use of traditional energies, violate certain basic assumptions a the underlying theory and require special attention in the application of pricing mechanism for internalizing externalities.

    Directory of Open Access Journals (Sweden)

    Dirk Hoerder

    2012-05-01

    Full Text Available Both migrations and attitudes towards them have deep historical roots. To pronounce the present migration and the economic crisis triggered by derivative bankers in the fall of 2008 as “new without historical precedent” overlooks the impact of patterns of the past on the present and prevents an understanding being reached of continuities and comparisons. It is not migrants who are “uprooted”, as some would have it, but historical memory is deliberately being uprooted. This essay starts by addressing the multiple problems of present-day debates about migration and historicising the perspectives. It critiques the anti-immigrant ascriptions, labels and ideologies. It goes on to present the data and discuss the geographies of migrant trajectories in the context of translocal, transregional, transnational and global connectivity. An integrative Transcultural Societal Studies approach will be proposed. The essay will then deal with migrant agency, that is the actions of migrants, criticising “victimization” approaches and argue that Otherness is a resource as well as a framework for exploitation. Remittances will serve as an example of the intersection between migrant agency and states’ needs. The conclusion will briefly place the present in the context of global inequalities, of the economic aspect and of anti-immigrantism, as well as the ideological national-essentialist aspect.

    Full Text Available Abstract Background Sub-Saharan Africa faces a human resources crisis in the health sector. Over the past two decades its population has increased substantially, with a significant rise in the disease burden due to HIV/AIDS and recurrent communicable diseases and an increased incidence of noncommunicable diseases. This increased demand for health services is met with a rather low supply of health workers, but this notwithstanding, sub-Saharan African countries also experience significant wastage of their human resources stock. Methods This paper is a desk review to illustrate suggestions that the way human resources for health (HRH are trained and deployed in Africa does not enhance productivity and that countries are unable to realize the full potential expected from the working life of their health workers. The paper suggests data types for use in measuring various forms of "wastage". Results "Direct" wastage – or avoidable increases in loss of staff through factors such as emigration and death – is on the rise, perhaps as a result of the HIV/AIDS epidemic. "Indirect" wastage – which is the result of losses in output and productivity from health professionals' misapplied skills, absenteeism, poor support and lack of supervision – is also common. HIV/AIDS represents a special cause of wastage in Africa. Deaths of health workers, fear of infection, burnout, absenteeism, heavy workloads and stress affect productivity. Conclusion The paper reviews strategies that have been proposed and/or implemented. It suggests areas needing further attention, including: developing and using indicators for monitoring and managing wastage; enhancing motivation and morale of health workers; protecting and valuing the health worker with enhanced occupational safety and welfare systems; and establishing the moral leadership to effectively tackle HIV/AIDS and the brain drain.

    To describe decision factors and outcome of open surgical procedures in the management of children with stone. Between January 2004 and December 2008, 3969 surgical procedures were performed in 3053 children with stone disease. Procedures employed included minimally invasive techniques shockwave lithotripsy (SWL), percutaneous nephrolithotomy (PCNL), ureterorenoscopy (URS), perurethral cystolithotripsy (PUCL), percutaneous cystolithotripsy (PCCL), and open surgery. From sociomedical records demographics, clinical history, operative procedures, complications, and outcome were recorded for all patients. Of 3969 surgeries, 2794 (70%) were minimally invasive surgery (MIS) techniques to include SWL 19%, PCNL 16%, URS 18.9%, and PUCL+PCCL 16% and 1175 (30%) were open surgeries. The main factors necessitating open surgery were large stone burden 37%, anatomical abnormalities 16%, stones with renal failure 34%, gross hydronephrosis with thin cortex 58%, urinary tract infection (UTI) 25%, and failed MIS 18%. Nearly 50% of the surgeries were necessitated by economic constraints and long distance from center where one-time treatment was preferred by the patient. Stone-free rates by open surgeries were pyelolithotomy 91%, ureterolithotomy 100%, and cystolithotomy 100% with complication rate of upto 3%. In developing countries, large stone burden, neglected stones with renal failure, paucity of urological facilities, residence of poor patients away from tertiary centers necessitate open surgical procedures as the therapy of choice in about 1/3rd of the patients. Open surgery provides comparable success rates to MIS although the burden and nature of disease is more complex. The scope of open surgery will remain much wide for a large population for considered time in developing countries.

    This paper reports a study to inform curriculum development by exploring the contribution of bioscience education programmes to nurses' clinical practice, their understanding of the rationale for practice, and their perceptions of their continuing professional development needs. The future of the health services worldwide depends on nurse education programmes equipping practitioners to deliver safe and effective patient care. In the developed world, the structure and indicative content of nursing curricula have been debated extensively. However, despite the rapid expansion in nursing roles brought about by social change, there is little information on the educational needs of nurses in developing countries. This study was undertaken in government teaching hospitals in Cape Town, South Africa in 2003. A purposive sample of 54 nurses from a range of clinical settings completed questionnaires and described critical incidents where bioscience knowledge had directed practice. Questionnaires were analysed descriptively, in the main. Analysis of critical incident reports was based on Akinsanya's bionursing model. Most nurses felt that their understanding of the biological, but not the physical sciences, was adequate or better: all felt confident with their knowledge of anatomy, compared with 57.4% (31/54) for microbiology. Respondents attributed the successes and failures of their education programmes to their teachers' delivery of content, ability to relate to practice and management of the process of learning. The biological, but not the physical, sciences were universally (96-100%) regarded as relevant to nursing. However, the critical incidents and nurses' own reports indicated a need for further education in pharmacology (40/54, 74.1%) and microbiology (29/54, 53.7%). To meet the needs of nurses in developing countries, and empower them to meet the increasingly complex demands of their expanding roles, nurse educators need to consider increasing the curriculum

    Full Text Available Arnason and Raaflaub’s edited volume, The Roman Empire in Context: Historical and Comparative Perspectives, is the fifth volume in a series entitled The Ancient World: Comparative Histories. The overarching aim of the series is to bring a comparative perspective to studies of ancient histories, and earlier titles focus either on content or geography. This is the only volume to date that focuses on a specific civilization, and Rome is of course significant enough to merit its own volume.

  13. M-Learning Adoption: A Perspective from a Developing Country

    2012-06-01

    Full Text Available M-learning is the style of learning for the new millennium. Decreases in cost and increases in capabilities of mobile devices have made this medium attractive for the dissemination of knowledge. Mobile engineers, software developers, and educationists represent the supply side of this technology, whereas students represent the demand side. In order to further develop and improve this medium of learning it is imperative to find out students’ perceptions about m-learning adoption. To achieve this objective a survey was conducted among the students of 10 chartered universities operating in the twin cities of Rawalpindi and Islamabad in Pakistan. The results indicate that perceived usefulness, ease of use, and facilitating conditions significantly affect the students’ intention to adopt m-learning, whereas perceived playfulness is found to have less influence. Social influence is found to have a negative impact on adoption of m-learning. The findings of this study are useful in providing guidance to developers and educators for designing m-learning courses specifically in the context of developing countries.

  14. On the concept of “variant” in lexicon studies from a historic-variational perspective

    Directory of Open Access Journals (Sweden)

    Américo Venâncio Lopes Machado Filho

    2014-02-01

    Full Text Available Even though the concept of linguistic variant has been fully established in contemporary sociolinguistic studies, it demands a theoretical review when it is considered from the perspective of lexicon studies, especially when related to historical and variational biases. In this paper, we present limits on identification and characterization of lexical variation, considering formal changes that may occur at other levels of analysis, especially at the morphological or phonetic ones. To support the reflections on the topic, we discuss the process of lexicon constitution in Portuguese and the results of etymological convergence and divergence present in the history of the language. Based on the analysis presented, it is proposed that research on lexical variation should incorporate to this notion any significant formal or content changes.

  15. Hunger strikers: historical perspectives from the emergency management of refugee camp asylum seekers.

    2013-12-01

    The treatment of hunger strikers is always contentious, chaotic and complex. The management is particularly difficult for health professionals as it raises unprecedented clinical, ethical, moral, humanitarian, and legal questions. There are never any easy answers. The current situation of prisoners from the Iraq and Afghanistan Wars currently at the Guantanamo Bay Detention Center in Cuba demands unprecedented transparency, accountability and multilevel coordination to ensure that the rights of the strikers are properly met. There are scant references available in the scientific literature on the emergency management of these tragedies. This historical perspective documents the complex issues faced by emergency physicians in Hong Kong surrounding refugee camp asylum seekers from Vietnam in 1994 and is offered as a useful adjunct in understanding the complex issues faced by emergency health providers and managers.

    Racial and ethnic identity matter and are salient for people in the workplace--a place where people spend a substantial amount of their time. This special issue brings the workplace into the domain of racial and ethnic minority psychology. It also brings to the study of the workplace a relatively neglected perspective: that of people from historically stigmatized racial and ethnic groups. Though there is, of course, need for more work with different themes, outcomes, and populations, this special issue takes us an important step in the direction of understanding better and giving voice to the experiences of racial and ethnic minorities in the workplace.

    The production and purification of some thorium compounds has been performed in the IPEN in the last 15 years. Some raw materials have been employed in this production, obtained from the monazite exploitation in industrial scale that it was performed in Sao paulo during the period 1948 until 1994. More than 160 t of high purity thorium nitrate were produced, purified by the solvent extraction process. The thorium nitrate has been supplied for the Brazilian portable gaslight industry to the production of Welsbach Mantle. Nowadays, a new facility is being designed and built. The main concern is the recovering of the production capacity, lost after some years of operation without suitable maintenance. This activity has an important strategic role, considering the huge Brazilian thorium resources and the renewed interest in thorium fuel cycle. This paper describes a brief historical background of thorium activities in the IPEN as well as their perspectives. (author)

  19. Searching for social capital: historical perspectives on health, poverty and culture.

    Science.gov (United States)

    Welshman, John

    2006-11-01

    Social capital has been seen as having a positive effect on health, and the concept of social capital has been viewed as of central importance to debates about healthy, sustainable communities. More generally, behaviour and its relationship with health has become much more central to policy-making, as illustrated in the Choosing Health White Paper (2005), and the concept of social capital has been one influence on the concept of social exclusion. Robert Putnam's arguments, both those expressed in Making Democracy Work (1993) and the revised version seen in Bowling Alone (2000) have been taken up by numerous social scientists and policy-makers. But despite the explicitly historical perspective that Putnam employs in Bowling Alone in particular, the history of social capital remains rather neglected in the available literature. This article is concerned with providing a historical perspective on social capital, especially the ways in which social investigators have viewed the relationships between health, poverty and behaviour. The article puts social capital alongside that of 'underclass' concepts such as the culture of poverty thesis, and examines how the latter has been invented and reinvented in the U.K. and the U.S.A. over the last 120 years. It argues that there are important similarities between the culture of poverty and social capital, but also significant differences, and these have implications for current policy initiatives. One way of analysing concepts like social capital and social exclusion more rigorously is by locating them within this longer-term history of social investigation, in which debates about health, poverty, and culture have been of

  20. Strategy for Self-Centered Development from the Perspective of an Historical Analysis of Development

    Directory of Open Access Journals (Sweden)

    Alfredo Pérez Sánchez

    1998-04-01

    Full Text Available After acknowledging the three phases of historical analysis of development, and especially considering the research work done in the last twenty-five years by the Germans Dieter Sengcheus and Ulrich Mezel, the author presents the principle elements of a self-centered development strategy which highlights the following perspectives:dissociation, economic restructuring, and the new forms of an international division of labor among Third World economies.This document calls into question the underlying operation of the conventional theory of development and its current policy, which call for the increasing integration of the Third World in the world market as a means of going beyond development as it is commonly understood. Though being an integral element in the theory of self-centereddevelopment, temporary dissociation from the world market is proposed. The justification for the strategy of dissociation, excepting the recourse to some historical and paradigmatic reflections sketched by Friedrich List, has kept itself, of necessity, to the global and abstract level. This position is nothing, however, but a most direct analytical result deduced fromthe principle theoretical beginnings and the empirical observations of both the Theory of Dependence and Peripheral Capitalism. Although the review vents its criticism on (and mainly questions the practicality of the aforesaid conception, a more penetratingunderstanding of what the wager for such a strategy entails is found. Thus, the notion of self-centered development influences and gives impulse to a most extensive ideologicallymarked debate about the alternative conceptions of development.

  1. Heritage Conservation and Urban Landscaping of Ancient Pan Pool Neighborhood, Qufu: a Historical and Indigenous Perspective

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Gu Pan Pool neighborhood got its name because of Gu Pan Chi, (古泮池,the ancient Pan Pool, located in the southeastern part of Confucius’ birthplace, Qufu, the birth place of Confucius with a history of 3000 year. Gu Pan Pool has been recently under preservation with the joint efforts of World Bank cultural heritage conservation project and the local municipal government. With disparate interests in mind, the three stakeholders of heritage, the world bank, Qufu municipal government and local residents are contradictory with each other in the regeneration process, in which the local voices are often ignored. The purpose of this paper is to rethink heritage making from a historical and indigenous perspective in the contemporary Chinese urban historic landscape planning process. The author contends that the cultural value and pluralism embedded in the ritual way of thinking in Chinese Classics inherited and transmitted for thousands of years could be an alternative way of thinking for the landscape planning practices in the homogenizing culture of global capitalism. This research aims to reinterpret and re-activate Confucianism as cultural heritage to enrich the understanding and hence the sustainability related to human action in urban spaces with emphasis on planning processes in contemporary China.

  2. Medical dominance in Canada in historical perspective: the rise and fall of medicine?

    Science.gov (United States)

    Coburn, D; Torrance, G M; Kaufert, J M

    1983-01-01

    Freidson's concept of medical dominance is compared to the alternative conceptions of neo-Marxist writers. Dominance is then examined in historical perspective, using medicine in Canada (mainly Ontario) as a case study. Medicine emerged as the dominant health occupation in Canada in the late 19th and early 20th centuries, consolidating its power between World War I and the Saskatchewan doctors' strike of 1962. The authors argue that medical dominance has declined since that time due to such factors as the involvement of the state in health insurance, the rise of other health occupations, increasing public or at least elite skepticism, and possible internal fragmentation. The underlying social explanation for this historical process is sought in changes in the Canadian class structure, specifically the spread of the capitalist mode of production, the decline of the petite bourgeoisie, and the rise of the state. It is suggested that Freidson's specific accounts of the history of medicine must be incorporated for explanatory purposes within the broader neo-Marxist view of medicine as an intermediary rather than an ultimately determining institution.

  3. Modernity Strikes Back? A Historical Perspective on the Latest Increase in Interpersonal Violence (1960–1990

    Directory of Open Access Journals (Sweden)

    Manuel Eisner

    2008-11-01

    Full Text Available There is a plethora of criminological explanations why criminal violence increased during the three decades between the early 1960s and the early 1990s. This paper argues that most available interpretations are lacking in three respects: they lack a historical perspective that anchors the three critical decades in a wider understanding of long-term trends; they take the nation-state as their unit of analysis and disregard important commonalities across the Western world; and they pay insufficient attention to different trends in broad categories of physical violence. This paper therefore takes a macro-level and long-term perspective on violent crime, focussing on European homicide during the past 160 years. It demonstrates that the period of increase was preceded by a long-term decline and convergence of homicide rates from the 1840s to the 1950s. Also, it shows that both the decline and the increase primarily resulted from temporal variation in the likelihood of physical aggression between men in public space. It argues that explanations of these common trends need to take into account broad long-term cultural change common to Western societies. In particular, the paper suggests that shifts in culturally transmitted and institutionally embedded ideals of the conduct of life may provide an explanation for long-term change in levels of interpersonal violence.

    Synyutka Nataliya G.

    2017-03-01

    Full Text Available The aim of this publication is improving the knowledge about the genesis of formation of offshore jurisdictions. The article characterizes the historical stages of origination of tax havens on the basis of theoretical generalizations and comparing the results of studies and publications on the specified issues. The article identifies the main groups of tax havens: offshores of the colonies of the former British Empire; the European havens; the group of simulators (such as Panama, Uruguay, Dubai, new havens in the countries with transition economy and in African countries. A comprehensive list of offshores in terms of actors by the domestic classification has been provided. The authors suggest, as a timely measures, establishing a coordinated international campaign to counter the aggressive tax planning. For the purpose of stabilization of the internal capital markets, as well as success of the fiscal control, the main directions of the anti-offshore policy have been proposed as follows: unification of the taxation rules for residents and non-residents within the offshore countries; global limitation of the bank secrecy along with transparency of information for the taxation purposes, ensuring transparency of ownership and tracing of end the beneficiaries of assets; changing the model convention for the avoidance of double taxation and the data exchange.

  7. Economists, capitalists, and the making of globalization: North American free trade in comparative-historical perspective.

    Science.gov (United States)

    Fairbrother, Malcolm

    2014-03-01

    Why did globalization happen? Current explanations point to a variety of conditions under which states have made the free market policy changes driving international economic integration since the 1980s. Such accounts disagree, however, about the key actors involved. This article provides a reconciliation, showing how two different combinations of actors, and two different political economic pathways, have led to globalization in recent decades. In developed countries, mobilization by business has been central; elsewhere, technocrats both constrained and empowered by international finance have pursued globalization more independently of business. In both contexts, economists' technical authority has helped legitimate liberalization, despite the limited diffusion of their ideas. The article validates and elaborates this model using a comparative-historical study of how the United States, Canada, and Mexico proposed, negotiated, and ratified agreements for free trade in North America.

    Full Text Available I use energy cost share to characterize the role of energy in the economy. Specifically, I use an estimate of monetary expenditures for primary energy on an annualized basis for forty-four countries from 1978 to 2010 for natural gas, coal, petroleum, and electricity. I show that global energy cost share is significantly correlated to a one-year lag in the change in gross domestic product as well as measures of total factor productivity. Given the historical reduction in the relative cost of energy (including food and fodder for animate power since the start of the Industrial Revolution, combined with a global energy cost share estimate, I conclude that the turn of the 21st Century represents the time period with the cheapest energy in the history of human civilization (to date. This potential historical nadir for energy expenditures around 2000 has important ramifications for strategies to solve future social, economic, and environmental problems such as reducing annual emissions of greenhouse gases (GHGs. Rapidly decreasing annual GHG emissions while internalizing their costs into the economy might feedback to increase energy expenditures to such a degree as to prevent economic growth during that transition.

    The core objective of this paper is to elaborate on historically implemented promotion strategies of renewable energy sources and the associated deployment within the European electricity market. Hence, at a first glance, the historic development of renewable energy sources in the electricity (RES-E) sector is addressed on Member State and on sectoral level as well as consequently discussed according to available RES-E potentials and costs. The specific focus of this paper, are promotion strategies for RES-E options as they are the key driver of an efficient and effective RES-E deployment. Therefore, the paper depicts the main types of different promotion schemes and their properties. Additionally, several cases studies of different European Member States show an in-depth analysis of the different RES-E promotion schemes. In this context, special emphasises are put on the question of effective and efficient promotion scheme designs of different RES-E technologies. Generally, conducted research led to the conclusion, that technology specific financial support measures of RES-E performed much more effective and efficient than others did. Hence, it is not all about the common question of feed-in tariffs vs. quota systems based on tradable green certificates, but more about the design criteria of implemented RES-E support schemes.

  10. Political Economy, Capability Development, and Fundamental Cause: Integrating Perspectives on Child Health in Developing Countries

    Directory of Open Access Journals (Sweden)

    Rebekah Burroway

    2017-02-01

    Full Text Available Several dominant theoretical perspectives attempt to account for health disparities in developing countries, including political economy, the capability approach, and fundamental cause. This study combines the perspectives in a multi-level analysis of child malnutrition and diarrhea in order to gain a more comprehensive understanding of who faces increased health risks and who is shielded from them. Using the Demographic and Health Surveys and World Bank data, I estimate a series of models that predict the likelihood of child malnutrition and diarrhea, based on a set of country- and individual-level explanatory variables. Results suggest that at the individual-level, household wealth and maternal education are the most robust predictors of child health. These social factors are even more important than more proximate factors like clean water or sanitation. At the country-level, gross domestic product (GDP per capita reduces malnutrition, but does not significantly affect incidence of diarrhea. Contrary to the predominant economic development paradigm, health care and education are more important in accounting for the prevalence of diarrhea than GDP. Finally, trade in and of itself is not harmful to well-being in developing countries. It is when countries become too dependent on one or a few commodities that trade starts to have detrimental costs. Thus, a synthesis of theoretical frameworks best illustrates the complex web of social structural factors that manifest as unequal life chances for children.

  12. Resurgence of malaria in Bombay (Mumbai) in the 1990s: a historical perspective.

    Science.gov (United States)

    Kamat, V

    2000-06-01

    Bombay has achieved extraordinary success in controlling its malaria problem for nearly six decades by relying primarily on legislative measures and non-insecticidal methods of mosquito abatement. In 1992, however, malaria reemerged in Bombay with a vengeance. During 1992-1997, the city witnessed a manifold increase in the number of malaria cases diagnosed and treated by the public health system. The large number of malaria patients treated by private practitioners was not recorded by the municipal malaria surveillance system during this period. In 1995, at the peak of the resurgence, public health officials of the Municipal Corporation of Greater Bombay (MCGB) confirmed that 170 persons in the city had died due to malaria. The crisis was unprecedented in Bombay's modern public health history. In response to intense criticism from the media, the city's public health officials attributed the resurgence to the global phenomenon of mosquito-vector resistance to insecticides, and Plasmodium resistance to antimalarial chemoprophylaxis and treatment. Local scientists who investigated the problem offered no support to this explanation. So what might explain the resurgence? What factors led the problem to reach an epidemic level in a matter of two or three years? In addressing the above principal questions, this paper adopts a historical perspective and argues that in the resurgence of malaria in Bombay in the 1990s, there is an element of the 'presence of the past'. In many ways the present public health crisis in Bombay resembles the health scenario that characterized the city at the turn of the 19th century. It is possible to draw parallels between the early public health history of malaria control in Bombay, which was punctuated by events that followed the bubonic plague epidemic of 1896, and the present-day malaria epidemic punctuated by the threat of a plague epidemic in 1994. As such, the paper covers a long period, of almost 100 years. This time-depth is used to

    Aim. To perform a narrative review of spa therapy for management of the fibromyalgia syndrome (FMS), evaluating this traditional time-honored form of therapy in a historical perspective. Methods. Medline was searched using the terms “Spa therapy,” “Balneotherapy,” and “Fibromyalgia” between 1990 (year of ACR fibromyalgia criteria publication) and April 2013. The Cochrane database was also searched. Publications relating to the implementation of spa therapy and related practices over the centuries were identified through references, searched, and reviewed. Results. Reports of balneotherapy were described from diverse locations throughout Europe and Asia, and various forms of water-related therapy have been incorporated for many musculoskeletal indications. In the management of FMS, spa therapy has generally been shown to be well accepted and moderately effective for symptom reduction. Conclusion. While achieving high-quality evidence-based conclusions is difficult for complex natural therapies such as spa therapy, the existing evidence indicates a positive effect in management of FMS. In view of the long history of this modality in the management of rheumatic pain as well as the inherent difficulties related to pharmacological treatment, the role of spa therapy should currently be recognized as part of a therapeutic program for FMS.

    Directory of Open Access Journals (Sweden)

    JILL ROBBINS

    2009-01-01

    Full Text Available Vygotsky’s sociocultural/cultural historical theory emphasised the notion of semiotic mediation – or how thinking is transformed through signs (such as language and cultural tools (such as drawings from an intermental to an intramental plane. While the ideas of Vygotsky have become well-accepted within research in early childhood education in Australia, they are somewhat slower to be adopted within science education research. Yet they offer the potential for gaining new understandings of how young children’s thinking about the world develops. This article will demonstrate one way in which aspects of Vygotsky’s (1987-1999 work, particularly his ideas about semiotic mediation can inform analysis of children’s thinking about the world. Focusing on conversations with children about natural phenomena, and drawings they completed during those conversations, the analysis identifies a number of significant issues that are not normally revealed within the dominant forms of analysis which draw on constructivist perspectives. The findings, which reveal complex and dynamic aspects of children’s thinking, have implications for both teachers and researchers working with young children – especially within science education and science education research.

  17. Measuring retrograde autobiographical amnesia following electroconvulsive therapy: historical perspective and current issues.

    Semkovska, Maria; McLoughlin, Declan M

    2013-06-01

    Retrograde amnesia following electroconvulsive therapy (ECT) is a major concern for both patients and clinicians. In contemporary ECT research, retrograde autobiographical amnesia (RAA) is commonly measured with instruments assessing autobiographical memory (AM) consistency over time. However, normal AM recall loses in consistency with the passage of time, and time has a differential effect on stability of personal memories. In addition, experiencing depression is associated with a decreased ability to recall specific AMs, and this difficulty may persist in the euthymic phase of recurrent depression. Despite these scientific facts, relatively few attempts have been made to accurately measure the specific effect of ECT on AM independent of both normal and mood-associated forgetting over time. This major gap in our knowledge prevents us at present from objectively quantifying the nature and extent of RAA associated with ECT. In turn, this hinders our identifying and implementing strategies for prevention or remediation of AM deficits. The present article aims to provide an up-to-date review and historical perspective of this major methodological conundrum for ECT research, highlight current issues in retrograde amnesia assessment following ECT, and propose directions for future studies. In conclusion, we suggest methods to reliably and specifically measure the extent and progression over time of ECT-associated RAA independently from persistent depressive symptoms' contribution and normal loss in AM consistency over time.

    Full Text Available Finance do not stand on static variables like exact sciences, they are changeable and influenced from human actions. The question where to invest funds, is a crucial task for financial managers. The study aimed at assessing the portfolio risk of different asset managers of the Kosovo Pension and Saving Trust. In general, the assessment has been categorized in two historical perspectives. The first phase is an assessment of the portfolio risk of the fund from 2003 to 2009 and the second phase is from 2003 to 2013. In general, portfolio risk in the second stage has shown a reduction as compared to the first stage. However, the return side shows also a reduction in the second phase than the first one. The overall risk of Kosovo Pension and Saving Trust has been in accepted range. Majority of money have been invested in stocks which automatically exposes huge risk on KPST portfolio, since it is proven that financial markets are not stable and they are prone to asset bubbles.

    Full Text Available This article aims to analyze the play of make-believe for children with autism, focusing on the symbolic resources it uses in asserting roles. It is based on the theoretical contributions of the historical-cultural perspective, with Vygotsky as its main exponent. The research was carried out in a public school of Early Childhood Education, in Brasília. From the microgenetic analysis, the research had six children diagnosed with autism, at the ages of 4 and 6 years, included in Special Class, as participants. The play situations were videotaped and later transcribed in episode format. In the data analysis, we identified two axes, namely: 1 The construction of the role play and; 2 Assumption of roles by the child with autism: set design and imagery resources. The results reveal the role of the other (intentional participation in the constitution of play activity, especially the role of the adult. In addition, they demonstrate that pedagogical mediation, including the creation of 'scenarios', is fundamental for the extension of the symbolic experience of the child with autism.

    Pluripotent stem cells such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) provide great potential as cell sources for gene editing to generate genetically modified animals, as well as in the field of regenerative medicine. Stable, long-term ESCs have been established in laboratory mouse and rat; however, isolation of true pluripotent ESCs in domesticated animals such as pigs and dogs have been less successful. Initially, domesticated animal pluripotent cell lines were referred to as "embryonic stem-like" cells owing to their similar morphologic characteristics to mouse ESCs, but accompanied by a limited ability to proliferate in vitro in an undifferentiated state. That is, they shared some but not all the characteristics of true ESCs. More recently, advances in reprogramming using exogenous transcription factors, combined with the utilization of small chemical inhibitors of key biochemical pathways, have led to the isolation of iPSCs. In this review, we provide a historical perspective of the isolation of various types of pluripotent stem cells in domesticated animals. In addition, we summarize the latest progress and limitations in the derivation and application of iPSCs. Copyright © 2014 Elsevier Inc. All rights reserved.

    This perspective delineates the history of the National Organic Chemistry Symposium (NOS) and, in doing so, traces the development of organic chemistry over the past 88 years. The NOS is the premier event sponsored by the ACS Division of Organic Chemistry (ORGN) and has been held in odd-numbered years since 1925, with the exceptions of 1943 and 1945. During the 42 symposia, 332 chemists have given 549 plenary lectures. The role the NOS played in the launch of The Journal of Organic Chemistry and Organic Reactions and the initiation of the Roger Adams Award are discussed. Representative examples highlighting the chemistry presented in each era are described, and the evolution of the field is examined by assigning each NOS talk to one of seven subdisciplines and analyzing how the number of talks in each subdiscipline has changed over time. Comparisons of the demographics of speakers, attendees, and ORGN members are made, and superlatives are noted. Personal interest stories of the speakers are discussed, along with the relationships among them, especially their academic lineage. Logistical aspects of the NOS and their historical trends are reviewed. Finally, the human side of science is examined, where over the past century, the NOS has been intertwined with some of the most heated debates in organic chemistry. Conflicts and controversies involving free radicals, reaction mechanisms, and nonclassical carbocations are discussed.

    Full Text Available Lobbying is a legitimate and necessary political instrument in a democratic society. Politics is no longer a process which can be directed (in hierarchical structure] only by politicians elected to sit in Parliament or in Government. Nowadays, politics has largely become reliant on political counseling and external consultants (lobbyists] in different areas of social life (economy, science, etc.]. In many developed democracies, lobbying has been institutionalized through the adoption of relevant legislation. In transition countries, in order to lay grounds for the prospective action, it would be necessary (first of all] to prepare the society for the process of introducing the concept of lobbying into the legislative framework. In that context, this initial stage may include devising a straightforward and well-prepared public relations strategy which would justify its introduction and most transparently provide for its institutionalization.

    2017-07-01

    Full Text Available The article deals with the history and the problems of the Russian Orthodox Church in Denmark – and here seen in a Danish-Russian historical perspective, especially, in the last 300 years. The relations between the Danes and the Orthodox Church began, however, around 900 years before, in the Eastern European state of Kievan Rus. The article shows that the history of the church is closely linked to the political development in Russia. In this article, the history of the church and the changing Russian congregations will be illuminated in a historical perspective so that both the church and church buildings will throw a new light on the role of the Russian Church in both Danish and Russian history. In addition, it will be analysed to what extent trade policy, strategy and power policy and family relations have influenced the role and position of the Russian Church in Danish history.

    Efforts to promote the development of pediatric pharmacotherapy include regulatory frameworks and close collaboration between the US Food and Drug Administration and the European Medicines Agency. We characterized the current status of pediatric clinical trials conducted in the United States by the pharmaceutical industry, focusing on the involvement of the European Union member countries, to clarify the industry perspective. Data on US pediatric clinical trials were obtained from ClinicalTrials.gov . Binary regression analysis was performed to identify what factors influence the likelihood of involvement of European Union countries. A total of 633 US pediatric clinical trials that met inclusion criteria were extracted and surveyed. Of these, 206 (32.5%) involved a European Union country site(s). The results of binary regression analysis indicated that attribution of industry, phase, disease area, and age of pediatric participants influenced the likelihood of the involvement of European Union countries in US pediatric clinical trials. Relatively complicated or large pediatric clinical trials, such as phase II and III trials and those that included a broad age range of participants, had a significantly greater likelihood of the involvement of European Union countries ( P European Union countries, and (3) feasibility of clinical trials is mainly concerned by pharmaceutical industry for pediatric drug development. Additional incentives for high marketability may further motivate pharmaceutical industry to develop pediatric drugs.

    Document available in abstract form only, full text of document follows: The Ringhals site is situated on the Swedish southwest coastline. At the site, there are four operating nuclear power plants. Historically, the Swedish policy has been that the nuclear power plants were to be closed in 2010. The present position is to operate the units until their technical and economic lifetime has run out. The units shall be maintained and invested in to ensure a lifetime of at least 50 years, but the actions taken shall not limit the time to this date. When the initial surveillance capsules were evaluated, it was noted that the material properties of the weld material of unit 3 and 4 showed some deviations from the expected behaviour. Currently there is an extensive project running for re-evaluating the embrittlement situation from a long-term operating perspective. One part of the project is aimed at more accurately determining the fluence levels of the reactor pressure vessels (RPVs). The basis for the early evaluations of the dosimeters in the surveillance capsules and the corresponding fluence evaluation had an operating lifetime of 25 years as a target value. Therefore, the accuracy and refinement of the measurement and calculation were taken to be good enough to suit this life span. Looking back at the results from the dosimetry measurements there are a few discrepancies. Some of the dosimeters were disintegrated and some measurements had comparatively large uncertainties. When starting this project there were some re-evaluations done with the old fluence prediction model. For every new run and refinement there appeared new difficulties, and the decision was to start the evaluation from scratch. Then there are two questions remaining regarding the fluence: What is the current fluence level? What will the resulting fluence be after 60 years of operation, when we have up-rated output power of both reactors? This paper aims to describe the view of the fluence evaluation

    facilities will reach the end of their operational, lifetime and become candidates for decommissioning. Taking account of work done to date on nuclear facility decommissioning, it is timely to provide an up to date basis for ongoing and foreseen activities in this field. An evaluation of the state of the art, latest trends and current issues is desirable. The approach taken in this paper is to review, from a historical perspective, decommissioning issues either solved in recent years or under way, to assess progress, as well as remaining and new issues.

    The Japanese Medical Education system has been influenced by political events throughout the country's history. From long periods of isolation from the western world to the effect of world wars, Japan's training system for physicians has had to adapt in many ways and will continue to change. The Japanese medical education system was recently compared to the "Galapagos Islands" for its unusual and singular evolution, in a speech by visiting professor Dr. Gordon L. Noel at the University of Tokyo International Research center.1 Japanese medical schools are currently working to increase their students' clinical hours or else these students may not be able to train in the United States for residencies. Knowing the history of the Japanese Medical education system is paramount to understanding the current system in place today. Studying the historical foundation of this system will also provide insight on how the system must change in order to produce better clinicians. This article provides a glimpse into the medical system of another nation that may encourage needed reflection on the state of current healthcare training in the United States.

  10. Subsidiary historical disciplines at Yugoslav and Serbian universities: Their development and perspectives

    Directory of Open Access Journals (Sweden)

    Atlagić Marko P.

    2013-01-01

    Full Text Available Subsidiary historical disciplines are an important segment of the studies of history without which the history cannot achieve its main methodological goal. They are available for the purpose of history and historical scientific research. Also, they are of an immense importance for collecting and examining historical sources that is for heuristics. At the same time they are relevant for the judgment regarding choosing, valorization and the use of historical sources, namely for historical critique. In the modern period of the development of teaching history at the universities, subsidiary historical disciplines were consisted mostly of Latin paleography, diplomatics and chronology. Since teaching at universities is being developed, the extension of subsidiary historical disciplines is also being slowly spread on sphragistics and numismatics so that nowadays they include Latin paleography, Slavic paleography, epigraphic, filigranology, diplomatics, chronology, genealogy, sphragistics, numismatics, historical metrology, toponomastics with topography and vexillology. Subsidiary historical disciplines became a part of the programmes for studying history at the end of the XVIII century while they were completely affirmed during the XIX century. However, that practice was not included in Yugoslav and especially not in Serbian universities where subsidiary historical disciplines should have been given the first place in the programmes for studying history as well as in their practical use.

  12. Designing Online Interaction to Address Disciplinary Competencies: A Cross-Country Comparison of Faculty Perspectives

    Directory of Open Access Journals (Sweden)

    Elena Barberà

    2014-04-01

    Full Text Available This study was conducted at colleges in three countries (United States, Venezuela, and Spain and across three academic disciplines (engineering, education, and business, to examine how experienced faculty define competencies for their discipline, and design instructional interaction for online courses. A qualitative research design employing in-depth interviews was selected. Results show that disciplinary knowledge takes precedence when faculty members select competencies to be developed in online courses for their respective professions. In all three disciplines, the design of interaction to correspond with disciplinary competencies was often influenced by contextual factors that modify faculty intention. Therefore, instructional design will vary across countries in the same discipline to address the local context, such as the needs and expectations of the learners, faculty perspectives, beliefs and values, and the needs of the institution, the community, and country. The three disciplines from the three countries agreed on the importance of the following competencies: knowledge of the field, higher order cognitive processes such as critical thinking, analysis, problem solving, transfer of knowledge, oral and written communication skills, team work, decision making, leadership and management skills, indicating far more similarities in competencies than differences between the three different applied disciplines. We found a lack of correspondence between faculty’s intent to develop collaborative learning skills and the actual development of them. Contextual factors such as faculty prior experience in design, student reluctance to engage in collaborative learning, and institutional assessment systems that focus on individual performance were some of these reasons.

  13. Poseidon's paintbox : historical archives of ocean colour in global-change perspective

    Wernand, M. R.

    2011-11-01

    In the thesis introduction issues are discussed on the historical background of marine optics and on marine optical devices that were used over the past centuries to observe and measure; as in all sciences, in marine optics we can see a steady development: that of ‘measuring’, beginning many centuries ago, to 'knowing' and since less than a century to the understanding of the phenomenon. Hereafter, six themes are treated successively. The first theme, ‘Ocean optics from 1600 (Hudson) to 1930 (Raman), shift in interpretation of natural water colouring’, addresses the question of why it took so long a time to explain the phenomenon ‘the colouring of the sea’, especially the blue colour, despite the age-long interest of sailors, for practical purposes of navigation and detection of fish - of which more later. The second theme ‘On the history of the Secchi disc’, describes the search to establish methods for the determination of (sea) water clarity concerning purposes of navigation (near coast colour changes) just mentioned to detect shoals, and for a more basic purpose, tracing lost objects. The search to determine the clarity of lakes and seas culminated in the invention of the Secchi disc, used since the late 19th century. The third theme, ‘Spectral analysis of the Forel-Ule ocean colour comparator scale’, addresses the accuracy of a colour scale proposed, used in limnology and oceanography. Scale observations are put into perspective with contemporary measurements on the colour of the sea. The fourth theme, ‘Ocean colour changes in the North Pacific since 1930’, handles the question whether long-term ocean colour changes using historic Forel-Ule observations, in this part of the ocean made very frequently over time, can be determined in relation to global change. In principal global warming may cause a gradual change in ocean colour due to the effect of biological, chemical and physical aspects of the ocean-surface. The fifth theme,

    Highlights: • Choice and arrangement of elastomeric inflatable and backup seals as primary and secondary barriers. • With survey (mid-1930s onwards) of reactor, sealing, R&D and rubber technology. • Load, reliability, safety, life and economy of seals and reactors are key factors. • PFBR blends concepts and experience of MOX fuelled FBRs with original solutions. • R&D indicates inflatable seal advanced fluoroelastomer pivotal in unifying nuclear sealing. - Abstract: Choice and arrangement of elastomeric primary inflatable and secondary backup seals for the rotatable plugs (RPs) of 500 MW (e), sodium cooled, pool type, 2-loop, mixed oxide (MOX) fuelled Prototype Fast Breeder Reactor (PFBR) is depicted with review of various historical perspectives. Static and dynamic operation, largest diameters (PFBR: ∼6.4 m, ∼4.2 m), widest gaps and variations (5 ± 2 mm) and demanding operating requirements make RP openings on top shield (TS) the most difficult to seal which necessitated extensive development from 1950s to early 1990s. Liquid metal freeze seals with life equivalent to reactor prevailed as primary barrier (France, Japan, U.S.S.R.) during pre-1980s in spite of bulk, cost and complexity due to the abilities to meet zero leakage and resist core disruptive accident (CDA). Redefinition of CDA as beyond design basis accident, tolerable leakage and enhanced economisation drive during post-1980s established elastomeric inflatable seal as primary barrier excepting in U.S.S.R. (MOX fuel, freeze seal) and U.S.A. (metallic fuel). Choice of inflatable seal for PFBR RPs considers these perspectives, inherent advantages of elastomers and those of inflatable seals which maximise seal life. Choice of elastomeric backup seal as secondary barrier was governed by reliability and minimisation as well as distribution of load (temperature, radiation, mist) to maximise seal life. The compact sealing combination brings the hanging RPs at about the same elevation to reduce

    Though the phenomenon of scientific tourism is widely spread in the USA and Europe, it is a new branch in Armenian tourism. The aim of the scientific tourism is to establish relationship between the tourist and the scientist, without the tourist having any material interest. The main aim is to involve the tourist in the scientific works, giving him a chance to be a part of the expedition. One of the main goals is also to involve the local tourist in the exploration of the historical and cultural heritage. It is important to mention that besides having the chance to take part in the scientific exploration, they also enjoy the time. It gives an opportunity to make the relation between the tourist and the scientist more strengthen, and let them partnering for future. The scientific tourism gives the scientist an opportunity to get new volunteers to make it wide known for the society. What refers to a tourist it is a good chance for him to be a part of a scientific exploration, to satisfy his own interest, to get new knowledge, and take part in the development of his own country.

    2017-08-01

    Full Text Available Work on the Dark Triad traits has benefited from the use of a life history framework but it has been limited to primarily Western samples and indirect assessments of life history strategies. Here, we examine how the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism relate to two measures of individual differences in life history strategies. In Study 1 (N = 937, we replicated prior observed links between life history strategies, as measured by the Mini-K, and the Dark Triad traits using samples recruited from three countries. In Study 2 (N = 1032, we measured life history strategies using the Consideration of Future Consequences Scale and correlated it with the Dark Triad traits in samples recruited from three additional countries. While there was some variability across participants’ sex and country, the results were generally consistent in that psychopathy and (to a lesser extent Machiavellianism were related to faster life history strategies and narcissism was related to slower life history strategies. These results add cross-cultural data and the use of two measures of life history speed to understand the Dark Triad traits from a life history perspective.

    Full Text Available Despite significant efforts to initiate electronic government projects, developing countries are still struggling to reap the benefits of using e-government services. An effective implementation of e-government infrastructure is necessary to increase the efficiency and transparency of the government services. There are several studies that observed causes like lack of infrastructure support, lack of payment gateway and improper e-government service delivery channel as main barriers to a wider adoption of e-government services. The main contribution of this research is to propose a cloud-based G2G (Government-to-government e-government framework for a viable e-government solution from the perspective of developing countries. We have introduced a list of concepts and a systematic process to guide the implementation of e-government project based on the government’s vision, goals, chosen services through the service delivery channel to the appropriate cloud service and deployment model. We have used Nepal as a context of the case study and applied the framework to a real e-government project of driving licensing department using action research methodology. The results from the study show that the G2G approach of e-government implementation would be the best for providing effective government services to the stakeholders of developing countries. The proposed framework also supports a smooth integration of government services and reduces the time of the overall project.

    To examine the subjective understanding of participation and integration of persons with spinal cord injuries from 5 European countries and to compare these findings with the International Classification of Functioning, Disability and Health (ICF)'s conceptualization of participation. Semi-structured interviews with 54 persons with acquired spinal cord injuries and 3 with spina bifida from 5 countries were examined using qualitative content analysis. Integration was most often associated with social acceptance and, furthermore, with ordinary performance, equality and freedom of choice. Participation was most often described as ordinary performance, with less emphasis on social acceptance and equality. However, participation and integration overlapped in people's narratives and were difficult to separate. The perception of participation and integration was largely similar across countries. In contrast to others, however, Finnish interviewees were more likely to associate participation with contributing to society. A variety of life domains was identified, of which recreation and leisure, work life, sports and going out were the most prevalent. While participation domains are well covered by the ICF, as is the notion of ordinary performance, interviewees also referred to a rights (e.g. acceptance) and duties (e.g. contribution) perspective.

    2016-11-01

    Full Text Available In this paper, several historical scenarios are compared, each very different to the each other in both institutional and geographical terms. What they have in common is the relative poverty of part of the population. This approach allows combining micro historical analysis (in the Catalan case with a macro comparative approach in developing countries. Through these micro historical and macro regression analyses we obtain the result that adult women’s skills and real wages are a key factor when we wish to explain the patterns of child labor. While female real wages increased sharply in 19th century Catalonia, we obtain very different results in the case of developing countries. This gender bias is identified as one of the very significant effects of human capital which held by women and helps to explain why in some cases children continue to work and also why some parts of the world continue to be poor according to our regression analysis.

    For centuries, difficulties have occurred in determining unresolved paternities. In addition to the modern standard methods, such as the examination of DNA or serological proof, expert opinion on fertility once played an important role. The andrological difference between incapability to fertilise and the inability to participate in sexual intercourse was also distinguished historically. Of special significance was the discovery of spermatozoa by the medical student Johan Ham in 1677 and their further investigation by Antoni van Leeuwenhoek.Recently, modern DNA methods have also been applied for historical investigations. Illustrious examples are the DNA analysis in the case of Kaspar Hauser of Ansbach and the dispute about Thomas Jefferson, President of the U.S., fathering a child by one of his slaves. In this discourse, a medicinal-forensic review of the development of expert opinion, illustrated with historical case studies, is given.

    Future oriented time perspective predicts a number of important health behaviors and outcomes, including smoking cessation. However, it is not known how future orientation exerts its effects on such outcomes, and no large scale cross-national studies have examined the question prospectively. The aim of the current investigation was to examine the relationship between time perspective and success in smoking cessation, and social cognitive mediators of the association. The ITC-4 is a multi-wave, four country survey (Australia, Canada, United States, United Kingdom) of current smokers (N=9772); the survey includes baseline measurements of time perspective, intentions, quit attempts, and self-reported quit status at follow-up over 8 years. We examined the predictive power of time perspective for smoking cessation, as mediated through strength of quit intentions and prior history of quit attempts. Findings indicated that those smokers with a stronger future orientation at baseline were more likely to have successfully quit at follow-up. This effect was partially explained by intention-mediated effects of future orientation on quit attempts. Future orientation predicts smoking cessation across four English-speaking countries; the cessation-facilitating effects of future orientation may be primarily due to future oriented individuals' motivated and sustained involvement in the quit cycle over time.

  8. Translating Bourdieu: cultural capital and the English middle class in historical perspective.

    Science.gov (United States)

    Gunn, Simon

    2005-03-01

    This article examines the ways in which Pierre Bourdieu's work on culture and cultural capital can be applied to the study of the English middle class in the nineteenth and twentieth centuries. Drawing on a wide historical literature, the article argues for the significance of culture as a constitutive element of middle-class identities in England since 1800. It goes on to examine Bourdieu's ideas of 'objectivated', 'instutionalized' and 'incorporated' cultural capital, in the context of family, inheritance, education and the body. The article identifies changes in the historical forms which cultural capital has taken and emphasizes the importance of analysing family processes of intergenerational transmission.

    2006-02-01

    Full Text Available Abstract Background Somatisation is particularly challenging in multicultural contexts where patients and physicians often differ in terms of their illness-related beliefs and practices and health care expectations. This paper reports on a exploratory study aimed at better understanding how asylum seeker and refugee patients from the former country of Yugoslavia who were identified by their physicians as somatising make sense of their suffering. Methods We conducted semi-structured interviews with 26 asylum seeker and refugee patients from the former country of Yugoslavia who attended the general medicine outpatient clinic of a Swiss teaching Hospital and were identified as presenting with somatisation. Interviews explored patients' illness perspectives and health care expectations. Interviews were audio taped, transcribed verbatim and analyzed to identify key themes in patients' narratives. Results Patients attributed the onset of symptoms to past traumatic experiences and tended to attribute their persistence to current living conditions and uncertain legal status. Patients formulated their suffering in both medical and social/legal terms, and sought help from physicians for both types of problems. Conclusion Awareness of how asylum seeker and refugee patients make sense of their suffering can help physicians to better understand patients' expectations of the clinical encounter, and the particular nature and constraints of the patient-provider relationship in the context of asylum.

  1. Historical contribution by country of three greenhouse gases (CO2, CH4, N2O) to the climate change and Equity principle

    2003-11-01

    The historical contribution by country to climate change can be used as a basis of analysis for a second period of commitments to the burden share. The historical greenhouse gases emission inventory is an important tool to evaluate the common but differentiated responsibilities of groups according to the principle of the UN Framework Convention on Climate Convention (1992). This paper aims to discuss the differences among the meaning of the GHG historical emissions in terms of development patterns and suggests that different weights for different sectors should be taken into account. GHG emissions due to enteric fermentation from domestic livestock, for example, are linked to different regional activities such as food production, cultural expression or even religion meaning, depending on the region analyzed. Emissions due to fossil fuel sector represent in the majority a not feasible consumption pattern in terms of sustainable development

  4. How three countries in the Americas are fortifying dietary salt reduction: a north and south perspective.

    Legowski, Barbara; Legetic, Branka

    2011-09-01

    A chronic disease/risk factor prevention framework with three policy environments--communications, physical and economic--was used to organize population level interventions that address the "over consumption of dietary salt", a key risk factor for cardiovascular diseases. The framework was then used to map the population based strategies to reduce dietary salt consumption being applied in three countries in the Americas--Argentina, Canada and Chile--each with a history of multi-sector approaches to deal with the risk factors for chronic disease, offering a north versus south perspective. Results show that in all three countries policy instruments are concentrated in the communications environment, e.g., media and education campaigns and/or regulations for standardized information on the salt or sodium content of packaged food products. Notable gaps are the requirement for nutrient information on meals and food items prepared by food establishments and restrictions on advertising and marketing of foods to children. In the physical environment, referring to the sodium levels in commercially prepared foods and meals available on the market, voluntary reformulation of food products is underway at this time in the three countries. Argentina and Chile began with bread and have gradually added other food categories; Canada at the outset is addressing all food categories where products have added salt. Argentina alone is at this point actively approaching regulations to limit the salt content of food, preferring this over ongoing monitoring of voluntary targets. No government in the three counties has yet considered action in the economic environment, a complex area where the research on and initiatives to limit or disadvantage energy-dense food products to address obesity may also capture foods that are highly salted. In the meantime, with recent research estimating substantially higher gains in population health from government legislation to limit salt in foods

    Retroperitoneal sarcomas (RPS) have fascinated and intrigued physicians both past and present. Operative mortality rates were historically very high and complete resection was not possible for the majority of patients until only the last 2 decades. More recently, changes to the surgical approach and clinical decision-making in RPS have improved patient outcomes. With select integration of nonsurgical therapies, continued RPS-specific research, and ongoing collaborative efforts among major referral centers, the future appears promising. © 2017 Wiley Periodicals, Inc.

    Full Text Available Understanding the processes of historical land-use change is crucial to the research of global environmental sustainability. Here we examine and attempt to disentangle the evolutionary interactions between land-use change and its underlying causes through a historical lens. We compiled and synthesized historical land-use change and various biophysical, political, socioeconomic, and technical datasets, from the Qing dynasty to modern China. The analysis reveals a clear transition period between the 1950s and the 1980s. Before the 1950s, cropland expanded while forested land diminished, which was also accompanied by increasing population; after the 1980s land-use change exhibited new characteristics: changes in cropland, and decoupling of forest from population as a result of agricultural intensification and globalization. Chinese political policies also played an important and complex role, especially during the 1950s–1980s transition periods. Overall, climate change plays an indirect but fundamental role in the dynamics of land use via a series of various cascading effects such as shrinking agricultural production proceeding to population collapse and outbreaks of war. The expected continuation of agricultural intensification this century should be able to support increasing domestic demand for richer diets, but may not be compatible with long-term environmental sustainability.

    ABSTRACT In this paper, we attempt to analyse the respective influences of land-use and climate changes on the global and regional balances of soil organic carbon (SOC) stocks. Two time periods are analysed: the historical period 1901-2000 and the period 2000-2100. The historical period is analysed using a synthesis of published data as well as new global and regional model simulations, and the future is analysed using models only. Historical land cover changes have resulted globally in SOC release into the atmosphere. This human induced SOC decrease was nearly balanced by the net SOC increase due to higher CO2 and rainfall. Mechanization of agriculture after the 1950s has accelerated SOC losses in croplands, whereas development of carbon-sequestering practices over the past decades may have limited SOC loss from arable soils. In some regions (Europe, China and USA), croplands are currently estimated to be either a small C sink or a small source, but not a large source of CO2 to the atmosphere. In the future, according to terrestrial biosphere and climate models projections, both climate and land cover changes might cause a net SOC loss, particularly in tropical regions. The timing, magnitude, and regional distribution of future SOC changes are all highly uncertain. Reducing this uncertainty requires improving future anthropogenic CO2 emissions and land-use scenarios and better understanding of biogeochemical processes that control SOC turnover, for both managed and un-managed ecosystems.

    2015-10-01

    Full Text Available The collapse of the communist regime at the end of the twentieth century resulted in a wave of democratization in Central and Eastern Europe. While trying to establish democracy, many states in this region had to demonstrate their ability to protect human rights and to deal with the past of the repressive regime. As these states decided to join various human rights instruments they also became subject to certain obligations towards their people. One of these obligations is the requirement to provide remedies in case of human rights abuses, and the right to know the truth is recognized as part of it. Therefore the goal of this article is to identify the abilities of the victim of the communist regime to access the files of former secret services in post-communist countries in the light of the right to know the truth. The answer is provided using an analysis of international documents, historic, comparative and systemic methods, providing and evaluating the practice of different states dealing with the files of former secret services or government files of the repressive past and academic literature.

  13. [Evolution and new perspectives of health care financing in developing countries].

    2003-01-01

    Over the last twenty five years, the perspective of health care financing has dramatically changed in developing countries. In this context, it is worth reviewing the literature and the experiences in order to understand the major shifts on this topic. During the sixties, health care policies focused on fighting major epidemics. Programs were dedicated to reduce the threat to population health. Financing related to the mobilization of resources for these programs and most of them were not managed within national administrations. The success of these policies was not sustainable. After Alma Ata, primary health care became a priority but it took some years before the management of the health care district was introduced as a major topic. In the eighties, with the district policy and the Bamako Initiative, the economic approach became a major part of all health care policies. At that time, most of health care financing was related to cost recovery strategies. All the attention was then drawn on how it worked: Fee policies, distribution of revenues, efficient use of resources and so on. In the second half of the nineties, cost recovery was relegated to the back scene, health care financing policy then becoming a major front scene matter. Two major reasons may explain this change in perspective: HIV which causes a major burden on the whole health system, and fighting poverty in relation with debts reduction. In most developing countries, with high HIV prevalence, access to care is no longer possible within the framework of the ongoing heath care financing scheme. Health plays a major role in poverty reduction strategies but health care officials must take into account every aspect of public financing. New facts also have to be taken into account: Decentralization/autonomy policies, the growing role of third party payment and the rising number of qualified health care professionals. All these facts, along with a broader emphasis given to the market, introduce a need for

    Email communication between physicians and patients could improve access to and delivery of health care. Most of the literature studies about email communication between physicians and patients have been conducted in developing countries. Therefore, this study aims to analyze the practices, attitudes, and barriers of both physicians' and patients' use of email within the same health care setting of a developing country. A cross-sectional paper-based survey was conducted among 39 physicians and 500 patients at the Family Medicine clinics of the American University of Beirut, a tertiary academic medical center. Most of the surveyed patients and physicians reported that they would like to communicate through email and agreed that it is useful. However, only 19% of the patients have ever communicated with their physicians via email, and only 5.1% of physicians have often communicated with their patients via email. Almost half of the patients surveyed were unaware of the possibility of this form of communication, and only 17% reported that their physician offered them his or her email address. In addition, physicians and patients did not agree on the services to be provided by email communication. For instance, almost half of the patients indicated consultation for an urgent medical matter as suitable for email communication. The use of email communication in health care is still scarce. Patients and physicians have different perspectives of its use and importance. Further rigorous research is needed to clarify the advantages and disadvantages of this form of communication, especially in the developing world. Interested physicians are encouraged to establish appropriate personal policies for email communication with adequate announcement and patient education plans.

  16. Solar System Exploration Augmented by Lunar and Outer Planet Resource Utilization: Historical Perspectives and Future Possibilities

    Palaszewski, Bryan

    2014-01-01

    Establishing a lunar presence and creating an industrial capability on the Moon may lead to important new discoveries for all of human kind. Historical studies of lunar exploration, in-situ resource utilization (ISRU) and industrialization all point to the vast resources on the Moon and its links to future human and robotic exploration. In the historical work, a broad range of technological innovations are described and analyzed. These studies depict program planning for future human missions throughout the solar system, lunar launched nuclear rockets, and future human settlements on the Moon, respectively. Updated analyses based on the visions presented are presented. While advanced propulsion systems were proposed in these historical studies, further investigation of nuclear options using high power nuclear thermal propulsion, nuclear surface power, as well as advanced chemical propulsion can significantly enhance these scenarios. Robotic and human outer planet exploration options are described in many detailed and extensive studies. Nuclear propulsion options for fast trips to the outer planets are discussed. To refuel such vehicles, atmospheric mining in the outer solar system has also been investigated as a means of fuel production for high energy propulsion and power. Fusion fuels such as helium 3 (3He) and hydrogen (H2) can be wrested from the atmospheres of Uranus and Neptune and either returned to Earth or used in-situ for energy production. Helium 3 and H2 (deuterium, etc.) were the primary gases of interest with hydrogen being the primary propellant for nuclear thermal solid core and gas core rocket-based atmospheric flight. A series of analyses have investigated resource capturing aspects of atmospheric mining in the outer solar system. These analyses included the gas capturing rate, storage options, and different methods of direct use of the captured gases. While capturing 3He, large amounts of hydrogen and 4He are produced. With these two additional

    Lenders, H J Rob

    2017-11-01

    Regulation and intensive use of most of the world's large rivers, has led to dramatic decline and even to extinction of riverine fish populations like salmon and sturgeon in the river Rhine. In general this decline is considered an unwelcome side-effect of the Industrial Revolution and large-scale river regulation (c. 1800), but the deterioration of stocks of some species may have started well before the 19th century. For the river Rhine, data on fish landings as proxies of abundance in the period 1550-1950 can be derived from historical market prices, fisheries taxation and fishery and fish auctions statistics, especially for commercially interesting species like Atlantic salmon, sturgeon, Allis shad and Twaite shad. Most data from which abundance of these species can be derived, however, appear to be missing in historical sources until decline of the investigated species sets in and the species become economically scarce goods. Atlantic salmon in the Rhine catchment appears to be already in decline during Early Modern Times (post 1500 AD) after which time river regulation, pollution and intensified fisheries finished off the remaining stocks in the 20th century. Salmon decline caused a cascade in the River Rhine ecosystem as fisheries shifted to, especially, Allis shad and Twaite shad, followed by (near-)extinction of these species. Dropping yields of salmon fishery did not lead to increased sturgeon fishery, although numbers of sturgeon also dwindled to extinction in the river Rhine. The onset of sturgeon decline appears to coincide with the period of the first large regulation works. It is shown that historical-ecological data on fish abundance can quantitatively underpin detrimental long-term processes in river ecosystems. Copyright © 2016 Elsevier Ltd. All rights reserved.

  18. The Role of Stigma and Denormalization in Suicide-Prevention Laws in East Asia: A Sociocultural, Historical, and Ethical Perspective.

    Science.gov (United States)

    Chen, Justin A; Courtwright, Andrew; Wu, Kevin Chien-Chang

    In many Western countries, the criminalization and stigmatization of suicide has given way to a biomedical approach aimed at destigmatizing suicide and treating underlying mental illness. By contrast, in many East Asian countries, suicide has never historically been criminalized or stigmatized. High rates of suicide in Japan, South Korea, and Taiwan have recently led policy makers in those countries to pursue innovative suicide-prevention strategies. The intentional denormalization of harmful behaviors has been discussed in the public health and ethics literatures, particularly with regard to smoking cessation, and could represent a novel mechanism for preventing suicides in East Asia. Using examples from the sociocultural, historical, and legal discourses surrounding suicide in Western and East Asian contexts, we suggest that denormalization can be a justified, culturally relevant suicide-prevention strategy, but that care must be taken to avoid shaming or stigmatizing suicidal individuals. Specifically, we propose the term weak denormalization to refer to an ethically permissible strategy at the mildest end of a spectrum of denormalizing approaches-milder than the reintegrative shaming described in the criminal justice literature, and diametrically opposed to outright stigmatization, which is generally considered ethically impermissible. Given the severe stigma of mental illness in East Asia, adopting the dominant Western view of suicide as solely a psychiatric concern would not be justified. Weak denormalization strategies in East Asia should be culturally tailored and rigorously tested on a small scale. They should include social supports, praise for the bravery of those of who seek help, and strategies to reduce shame regarding perceived social failure.

    Physics as a discipline in El Salvador's higher education system has struggled historically; however, since 1991, it has enjoyed a growth-friendly environment. While there are few female physicists in El Salvador, they are employed in various organizations and educational institutions, demonstrating that physics is a viable career path. El Salvador currently offers a range of opportunities for women in physics. With the support of the 5th IUPAP International Conference on Women in Physics, we will both meet the challenges and take advantage of the opportunities that face female physicists in El Salvador.

    The aim of regenerative medicine is to reconstruct tissue that has been lost or pathologically altered. Therapeutic cloning seems to offer a method of achieving this aim; however, the ethical debate surrounding human therapeutic cloning is highly controversial. Artificial parthenogenesis—obtaining embryos from unfertilised eggs—seems to offer a way to sidestep these ethical pitfalls. Jacques Loeb (1859–1924), the founding father of artificial parthogenesis, faced negative public opinion when he published his research in 1899. His research, the public's response to his findings, and his ethical foundations serve as an historical argument both for the communication of science and compromise in biological research.

We tested whether berylline, blue-tailed and steely-blue hummingbirds, Amazilia beryllina, Amazilia cyanura and Amazilia saucerottei, show evidence of historical or current introgression as their plumage colour variation might suggest. We also analysed the role of past and present climatic events in promoting genetic introgression and species diversification. We collected mitochondrial DNA (mtDNA sequence data and microsatellite loci scores for populations throughout the range of the three Amazilia species, as well as morphological and ecological data. Haplotype network, Bayesian phylogenetic and divergence time inference, historical demography, palaeodistribution modelling, and niche divergence tests were used to reconstruct the evolutionary history of this Amazilia species complex. An isolation-with-migration coalescent model and Bayesian assignment analysis were assessed to determine historical introgression and current genetic admixture. mtDNA haplotypes were geographically unstructured, with haplotypes from disparate areas interdispersed on a shallow tree and an unresolved haplotype network. Assignment analysis of the nuclear genome (nuDNA supported three genetic groups with signs of genetic admixture, corresponding to: (1 A. beryllina populations located west of the Isthmus of Tehuantepec; (2 A. cyanura populations between the Isthmus of Tehuantepec and the Nicaraguan Depression (Nuclear Central America; and (3 A. saucerottei populations southeast of the Nicaraguan Depression.

The current study is assessing the historical development of MSWM in the municipality of Aalborg, Denmark throughout the period of 1970 to 2010, and its implications regarding Global Warming Potential (GWP 100 ), using the Life Cycle Assessment (LCA) approach. Historical data regarding MSW composition, and different treatment technologies such as incineration, recycling and composting has been used in order to perform the analysis. The LCA results show a continuous improvement in environmental performance of MSWM from 1970 to 2010 mainly due to the changes in treatment options, improved efficiency of various treatment technologies and increasing focus on recycling, resulting in a shift from net emission of 618 kg CO 2 -eq. tonne −1 to net saving of 670 kg CO 2 -eq. tonne −1 of MSWM

    Inauguration of the new political dispensation in South Africa, initiated a dynamic period in the historical development of its minerals policy. The process of substituting the current South African mineral policy framework with an acceptable `post apartheid` system, started soon after the 1994 election of the African National Congress (ANC) government. The Green Paper on a Minerals and Mining Policy for South Africa released for public discussion in February 1998, calls for radical transformation in mineral rights ownership. A shift towards exclusive state ownership of mineral rights, away from the present dual system of private and state ownership, is the most significant proposal. The current holders of mineral rights, or their nominees, who lawfully enjoyed security of tenure under past and present mineral laws are opposed to this transformation because mineral rights were often acquired at considerable cost. The situation is compounded by poor public record-keeping and passive mineral rights administration over a very long period. This paper represents a summary of the historical developments leading to the current legislative environment and forms the basis for any discussion on which future sculpturing of South Africa`s policy regarding mineral rights can take place. One cannot plan for the future without considering the past. 21 refs.

    While the HIV epidemic in South Africa had a later onset than epidemics in other southern African countries, prevalence grew rapidly during the 1990's when the country was going through socio-political changes with the end of Apartheid. South Africa currently has the largest number of people living with HIV in the world and the epidemic is dominated by a unique subtype, HIV-1 subtype C. This large epidemic is also characterized by high level of genetic diversity. We hypothesize that this diversity is due to multiple introductions of the virus during the period of change. In this paper, we apply novel phylogeographic methods to estimate the number of viral imports and exports from the start of the epidemic to the present. We assembled 11,289 unique subtype C pol sequences from southern Africa. These represent one of the largest sequence datasets ever analyzed in the region. Sequences were stratified based on country of sampling and levels of genetic diversity were estimated for each country. Sequences were aligned and a maximum-likelihood evolutionary tree was inferred. Least-Squares Dating was then used to obtain a dated phylogeny from which we estimated the number of introductions into and exports out of South Africa using parsimony-based ancestral location reconstructions. Our results identified 189 viral introductions into South Africa with the largest number of introductions attributed to Zambia (n=109), Botswana (n=32), Malawi (n=26) and Zimbabwe (n=13). South Africa also exported many viral lineages to its neighbours. The bulk viral imports and exports appear to have occurred between 1985 and 2000, coincident with the period of socio-political transition. The high level of subtype C genetic diversity in South Africa is related to multiple introductions of the virus to the country. While the number of viral imports and exports we identified was highly sensitive to the number of samples included from each country, they mostly clustered around the period of

    2016-04-01

    Research purpose: This article relates certain changes in HRM over time to the argument that there has been a shift from an industrial paradigm (on which many human resource [HR] systems, practices and theoretical frameworks are still based to a knowledge paradigm (of knowledge work, in which employee knowledge and skills offer compound advantages that are not substitutable which explains a great deal of the variance in changes of the field over time. Motivation for the study: It is argued that in order for the field to move forward, it may needto bring to the surface certain assumptions and differentiate between theoretical frameworkswhen dealing with knowledge work versus non-knowledge work. Research design, approach and method: This article offers a perspective of HR theory development over time. It is a conceptual/perspectives article and is not qualitative nor quantitative in nature. Further research will be able to test the ideas presented here. Practical/managerial implications: Managers and human resources managers need to differentiate between knowledge and non-knowledge work. The latter is associated with increased heterogeneity and complexity, and differences in power relationships, as knowledge work shifts power away from capital into the hands of skilled knowledge labour.

    Nuclear rocket research and development was initiated in the United States in 1955 and is still being pursued to a limited extent. The major technology emphasis occurred in the decade of the 1960s and was primarily associated with the Rover/NERVA Program where the technology for a nuclear rocket engine system for space application was developed and demonstrated. The NERVA (Nuclear Engine for Rocket Vehicle Application) technology developed twenty years ago provides a comprehensive and viable propulsion technology base that can be applied and will prove to be valuable for application to the NASA Space Exploration Initiative (SEI). This paper, which is historical in scope, provides an overview of the conduct of the NERVA Engine Program, its organization and management, development philosophy, the engine configuration, and significant accomplishments

    Full Text Available As international attention continues to focus on large dam projects across Asia, it is worth noting that conflicts over the politics of and environmental changes caused by dams in India are not new. Population dislocation, siltation, disease, floods caused by catastrophic dam failure, raised water tables, high costs and low returns-all of these concerns, and others, can be discussed in the context of reservoir projects ten, one hundred, or even one thousand years old. In this paper, I identify some of the major issues in the political ecology of contemporary dam projects and show how these same issues have played out in southern India over the last thousand years, suggesting that historical attention to the cultural and political context of reservoir construction might help us to understand some aspects of contemporary conflicts.

  18. Imperial nursing: cross-cultural challenges for women in the health professions: a historical perspective.

    Science.gov (United States)

    Schultheiss, Katrin

    2010-05-01

    This essay briefly examines some of the cross-cultural challenges that faced nurses in the Philippines, India, and South Africa in the context of 19th and 20th century imperialism. During this time, nurses from colonizing countries served as agents of empire by helping to establish and reinforce American and European control in colonized societies. In doing so, they sought to instill the racial and gender hierarchies of their home countries in the colonial territories. But once these women moved to the colonies, they frequently found their preconceptions about femininity, sexuality, and race challenged in unexpected ways. The history of nursing in the age of empire is a story of good intentions mixed with cultural chauvinism, of professional rigor mixed with condescension, of devotion and generosity shaped and often distorted by ideas of gendered and racial conventions, and of ambitious reform crushed by an inability to think beyond the bounds of imperialism.

  19. Roles of sunlight and natural ventilation for controlling infection: historical and current perspectives.

    Infections caught in buildings are a major global cause of sickness and mortality. Understanding how infections spread is pivotal to public health yet current knowledge of indoor transmission remains poor. To review the roles of natural ventilation and sunlight for controlling infection within healthcare environments. Comprehensive literature search was performed, using electronic and library databases to retrieve English language papers combining infection; risk; pathogen; and mention of ventilation; fresh air; and sunlight. Foreign language articles with English translation were included, with no limit imposed on publication date. In the past, hospitals were designed with south-facing glazing, cross-ventilation and high ceilings because fresh air and sunlight were thought to reduce infection risk. Historical and recent studies suggest that natural ventilation offers protection from transmission of airborne pathogens. Particle size, dispersal characteristics and transmission risk require more work to justify infection control practices concerning airborne pathogens. Sunlight boosts resistance to infection, with older studies suggesting potential roles for surface decontamination. Current knowledge of indoor transmission of pathogens is inadequate, partly due to lack of agreed definitions for particle types and mechanisms of spread. There is recent evidence to support historical data on the effects of natural ventilation but virtually none for sunlight. Modern practice of designing healthcare buildings for comfort favours pathogen persistence. As the number of effective antimicrobial agents declines, further work is required to clarify absolute risks from airborne pathogens along with any potential benefits from additional fresh air and sunlight.

  20. Religious morality (and secular humanism) in Western civilization as precursors to medical ethics: A historic perspective

    Science.gov (United States)

    Faria, Miguel A.

    2015-01-01

    In discussing bioethics and the formulation of neuroethics, the question has arisen as to whether secular humanism should be the sole philosophical guiding light, to the exclusion of any discussion (or even mention) of religious morality, in professional medical ethics. In addition, the question has arisen as to whether freedom or censorship should be part of medical (and neuroscience) journalism. Should independent medical journals abstain from discussing certain issues, or should only the major medical journals — i.e., the New England Journal of Medicine (NEJM), the Journal of the American Medical Association (JAMA) or Lancet — be heard, speaking with one “consensual,” authoritative voice? This issue is particularly important in controversial topics impacting medical politics — e.g., public health policy, socio-economics, bioethics, and the so-called redistributive justice in health care. Should all sides be heard when those controversial topics are discussed or only a consensual (monolithic) side? This historical review article discusses those issues and opts for freedom in medical and surgical practice as well as freedom in medical journalism, particularly in opinion pieces such as editorials, commentaries, or letters to the editor, as long as they relate to medicine and, in our special case, to neuroscience and neurosurgery. After answering those questions, and in response to a critical letter to the editor, this review article then expounds comprehensively on the historical and philosophical origins of ethics and religious morality. Necessarily, we discuss the Graeco-Roman legacy and the Judeo-Christian inheritance in the development of ethics and religious morality in Western civilization and their impact on moral conduct in general and on medical and neuroscience ethics in particular.

    This paper addresses, from the Brazilian perspective, the main problems with Joint Implementation/Activities Implemented Jointly (JI/AIJ) between industrialized (Annex I) and developing (non-Annex I) countries, as defined by the United Nations Framework Convention on Climate Change (UNFCCC). Four possible GHG emissions abatement measures are presented for Brazil: forest protection, reforestation projects for carbon sequestration or charcoal manufacturing, use of ethanol produced from sugar cane as a car fuel, and electrical energy conservation through an increase in end-use efficiencies. These four case studies form the basis of a discussion regarding the validity of developing countries' concerns about JI/AIJ. Recommendations are offered for overcoming the present shortcomings of JI/AIJ in developing countries. The primary conclusion is that Annex I countries' funding of JI/AIJ projects in developing countries in return for GHG emissions credits is not the best means to implement the UNFCCC. However, JI/AIJ projects can be a productive means of preventing global climate change if combined with other measures, including GHG emissions reduction targets for all countries involved in JI/AIJ projects and limits on the percentage of industrialized countries' emissions reductions that can be met through projects in developing countries.

    Recent discoveries of shipwrecked vessels in the northern reaches of the river Yenisei led to a number of questions concerning the history of shipbuilding in Siberia and the technical features of the first vessels of the industrial era to navigate the Northern Sea Route and the Yenisei. One of these questions addresses the features of mechanical fasteners used in the construction of the Siberian vessels. The answer to this question may provide information on how the first vessels, constructed in Siberia during the 1870’s, were able to sail the high seas of the Arctic Ocean and reach European ports. In this paper, we provide a description of iron mechanical fasteners obtained from one shipwrecked vessel and discuss on the perspectives of a metallurgical analysis This research has been funded by a grant of the Russian Fund of Humanities Research (Russian Fund of Fundamental Research) and the Krasnoyarsk Regional Science Fund under Grant number 16-11-24010.

    Research purpose: The purpose of the research was to describe the experiences of nine lecturers in a particular HBU. This was undertaken to analyse and interpret the conscious and unconscious diversity dynamics operating in the relationship between the students, lecturers and management, from the lecturers’ perspective. Motivation for the study: The researcher was interested in the nature of the diversity dynamics operating in the relationship between students, lecturers and management in an HBU, as a platform towards understanding diversity dynamics in educational institutions and South African organisations. Research design, approach and method: Qualitative and descriptive research approaches were used. Hermeneutic phenomenology, using the systems psychodynamic perspective, allowed for the description and interpretation of diversity dynamics operating in the relationship between the students, lecturers and management. The data were obtained through in-depth interviews with nine lecturers. Thematic analysis resulted in two broad themes for which a discussion was provided and a research hypothesis formulated. Main findings: Two broad themes manifested, firstly diversity characteristics and secondly struggle skills entrenching the Black and White divide. Practical/managerial implications: The research highlighted the importance of understanding the diversity dynamics operating in the relationship between students, lecturers and management. This was in order to develop our understanding of diversity dynamics operating in educational institutions specifically, and organisations in general. Contribution/value-add: The understanding about diversity dynamics is available for application, by lecturers and management, to form a different understanding of conscious and unconscious factors impacting on the relationship between the three stakeholders, and subsequently the effectiveness of the three stakeholders in their respective roles. This understanding can also be

    Different types of managed aquifer recharge (MAR) schemes are widely distributed and applied on various scales and for various purposes in the European countries, but a systematic categorization and compilation of data has been missing up to now. The European MAR catalogue presented herein contains various key parameters collected from the available literature. The catalogue includes 224 currently active MAR sites found in 23 European countries. Large quantities of drinking water are produced by MAR sites in Hungary, Slovakia, the Netherlands, Germany, Finland, Poland, Switzerland and France. This inventory highlights that, for over a century, MAR has played an important role in the development of European water supply and contributes to drinking-water production substantially. This development has occurred autonomously, with "trial-and-error" within the full range of climatically and hydrogeologically diverse conditions of the European countries. For the future, MAR has the potential to facilitate optimal (re)use and storage of available water resources and to take advantage of the natural purification and low energy requirements during MAR operations. Particularly with respect to the re-use of wastewater treatment-plant effluent and stormwater, which is currently underdeveloped, the use of MAR can support the public acceptance of such water-resource efficient schemes. Particularly for the highly productive and urbanized coastal zones, where the pressure on freshwater supplies increases by growing water demand, salinization and increased agricultural needs for food production (such as along the Mediterranean and North Sea coasts), MAR is expected to be increasingly relied on in Europe.

There are many handicaps before democratisation in Egypt: the elite’s stake in the authoritarian rule, widespread political extremism, structural problems within the political culture of the country in terms of democracy etc. This article ultimately argues that Egyptian democratisation process seems to be a painful and bloody process, but in the long term after the Arab Spring, the clock is ticking in favour of democracy.

    Cancer is considered as one of the most serious health problems today. The discovery of nitrogen mustard as an alkylating agent in 1942, opened a new era in the cancer chemotherapy. This valuable class of alkylating agent exerts its biological activity by binding to DNA, cross linking two strands, preventing DNA replication and ultimate cell death. At the molecular level, nitrogen lone pairs of nitrogen mustard generate a strained intermediate "aziridinium ion" which is very reactive towards DNA of tumor cell as well as normal cell resulting in various adverse side effects alogwith therapeutic implications. Over the last 75 years, due to its high reactivity and peripheral cytotoxicity, numerous modifications have been made in the area of nitrogen mustard to improve its efficacy as well as enhancing drug delivery specifically to tumor cells. This review mainly discusses the medicinal chemistry aspects in the development of various classes of nitrogen mustards (mechlorethamine, chlorambucil, melphalan, cyclophosphamide and steroidal based nitrogen mustards). The literature collection includes the historical and the latest developments in these areas. This comprehensive review also attempted to showcase the recent progress in the targeted delivery of nitrogen mustards that includes DNA directed nitrogen mustards, antibody directed enzyme prodrug therapy (ADEPT), gene directed enzyme prodrug therapy (GDEPT), nitrogen mustard activated by glutathione transferase, peptide based nitrogen mustards and CNS targeted nitrogen mustards.

    O'Malley, Maureen A

    2012-01-01

    Systems biology (SB) is at least a decade old now and maturing rapidly. A more recent field, evolutionary systems biology (ESB), is in the process of further developing system-level approaches through the expansion of their explanatory and potentially predictive scope. This chapter will outline the varieties of ESB existing today by tracing the diverse roots and fusions that make up this integrative project. My approach is philosophical and historical. As well as examining the recent origins of ESB, I will reflect on its central features and the different clusters of research it comprises. In its broadest interpretation, ESB consists of five overlapping approaches: comparative and correlational ESB; network architecture ESB; network property ESB; population genetics ESB; and finally, standard evolutionary questions answered with SB methods. After outlining each approach with examples, I will examine some strong general claims about ESB, particularly that it can be viewed as the next step toward a fuller modern synthesis of evolutionary biology (EB), and that it is also the way forward for evolutionary and systems medicine. I will conclude with a discussion of whether the emerging field of ESB has the capacity to combine an even broader scope of research aims and efforts than it presently does.

  10. The Composition of Cigarette Smoke. An Historical Perspective of Several Polycyclic Aromatic Hydrocarbons

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Because of the significant advancements in fractionation, analytical, and characterization technologies since the early 1960s, hundreds of components of complex mixtures have been accurately characterized without the necessity of actually isolating the individual component. This has been particularly true in the case of the complex mixtures tobacco and tobacco smoke. Herein, an historical account of a mid-1950 situation concerning polycyclic aromatic hydrocarbons (PAHs in cigarette smoke is presented. While the number of PAHs identified in tobacco smoke has escalated from the initial PAH, azulene, identified in 1947 to almost 100 PAHs identified by late 1963 to more than 500 PAHs identified by the late 1970s, the number of PAHs isolated individually and characterized by several of the so-called classical chemical means (melting point, mixture melting point, derivative preparation and properties in the mid-1950s and since is relatively few, 14 in all. They were among 44 PAHs identified in cigarette mainstream smoke and included the following PAHs ranging from bicyclic to pentacyclic: Acenaphthylene, 1,2-dihydroacenaphthylene, anthracene, benz[a]anthracene, benzo[a]pyrene, chrysene, dibenz[a, h]anthracene, fluoranthene, 9H-fluorene, naphthalene, 1-methylnaphthalene, 2-methylnaphthalene, phenanthrene, and pyrene. One of them, benzo[a]pyrene, was similarly characterized in another study in 1959 by Hoffmann.

  11. “Grammar-translation” method, a linguistic historic err or of perspective: origins, dynamics and inconsistencies

    2013-07-01

    Full Text Available The Grammar-Translation method is frequently referred to as the traditional ineffective approach par excellence. Such view is often justified by the claim that before the Audiolingual method oral performance in foreign language was not reached, and language classes were reduced to memorizing grammar rules and lists of vocabulary. Nevertheless, this opinion is derived from unproved claims, mainly made by misinformed authors for they offer no compelling empirical evidence to validate their restrictive descriptions where translation is shown as an invalid metacognitive strategy. The aim of this paper is to demonstrate that Grammar-Translation is merely an arbitrary historic label, developed by methodologists and theoreticians to encompass the history of language teaching from 1790 through 1950. References to Grammar-Translation are critically reviewed to make evident they are biased inferences based on partial evidence to account for the existence of any such methodology. The assumption that Grammar-Translation did exist, and that it is the negative model of teaching practices that should be better avoided at all costs, might reflect an unconstructive and unfounded ideological interest of mainstream theoreticians and unsuspecting teachers.

    Achieving solid osseous fusion across the lumbosacral junction has historically been, and continues to be, a challenge in spine surgery. Robust pelvic fixation plays an integral role in achieving this goal. The goals of this review are to describe the history of and indications for spinopelvic fixation, examine conventional spinopelvic fixation techniques, and review the newer S2-alar-iliac technique and its outcomes in adult and pediatric patients with spinal deformity. Since the introduction of Harrington rods in the 1960s, spinal instrumentation has evolved substantially. Indications for spinopelvic fixation as a means to achieve lumbosacral arthrodesis include a long arthrodesis (five or more vertebral levels) or use of three-column osteotomies in the lower thoracic or lumbar spine, surgical treatment of high-grade spondylolisthesis, and correction of lumbar deformity and pelvic obliquity. A variety of techniques have been described over the years, including Galveston iliac rods, Jackson intrasacral rods, the Kostuik transiliac bar, iliac screws, and S2-alar-iliac screws. Modern iliac screws and S2-alar-iliac screws are associated with relatively low rates of pseudarthrosis. S2-alar-iliac screws have the advantages of less implant prominence and inline placement with proximal spinal anchors. Collectively, these techniques provide powerful methods for obtaining control of the pelvis in facilitating lumbosacral arthrodesis.

  13. Death, bereavement and traumatic loss in Israel: a historical and cultural perspective.

    Science.gov (United States)

    Witztum, E; Malkinson, R; Rubin, S S

    2001-01-01

    In the present article, we focus on the experience of bereavement and traumatic loss in Israel and examine the main influences that continue to shape them. For the Jewish population the main features are: religious aspects stemming from Jewish tradition and its variants; the secular and contemporary traditions, the ethos of the Israeli state, and the influence of the struggle to reestablish the Jewish people in its homeland. In an increasingly multicultural society, significant changes are occurring. A series of vignettes of grief and mourning illustrate current issues and practices among religious, secular, kibbutz, Russian and Ethiopian segments of society. The remainder of the article discusses emerging patterns of response to bereavement that are socially constructed and historically situated. We follow the variations in these patterns, from shifting forms of memorialization on the collective level to changes in expressive mood on the individual level, which are mediated by the cultural mosaic of the society. Mental health professionals would benefit from an understanding of the multifaceted fabric of beliefs and cultural-specific customs that shape the mourning rituals and their meanings for the bereaved.

  14. Historical Perspectives and Future Needs in the Development of the Soil Series Concept

    2016-04-01

    The soil series concept is an ever-evolving understanding of soil profile observations, their connection to the landscape, and functional limits on the range in characteristics that affect management. Historically, the soil series has played a pivotal role in the development of soil-landscape theory, modern soil survey methods, and concise delivery of soils information to the end-user-- in other words, soil series is the palette from which soil survey reports are crafted. Over the last 20 years the soil series has received considerable criticism as a means of soil information organization (soil survey development) and delivery (end-user application of soil survey data), with increasing pressure (internal and external) to retire the soil series. We propose that a modern re-examination of soil series information could help address several of the long-standing critiques of soil survey: consistency across survey vintage and political divisions and more robust estimates of soil properties and associated uncertainty. A new library of soil series data would include classic narratives describing morphology and management, quantitative descriptions of soil properties and their ranges, graphical depiction of the relationships between associated soil series, block diagrams illustrating soil-landscape models, maps of series distribution, and a probabilistic representation of a "typical" soil profile. These data would be derived from re-correlation of existing morphologic and characterization data informed by modern statistical methods and regional expertise.

  15. Canadian upstream oil and gas industry profitability: Historical review and future perspectives [with executive summary

    International Nuclear Information System (INIS)

    1991-09-01

    The profitability of the Canadian upstream oil and gas industry is examined by analyzing return on equity and return on capital invested. By all measures and interpretations, the upstream industry has been unprofitable since the mid-1980s; returns generated are far below the industry's own historical cost of capital, and are inadequate relative to other sectors of the Canadian economy and to international oil and gas companies. This poor profitability is attributed to such factors as: overly optimistic price forecasts and healthy cash flows generated in the early 1980s, which led to excess capital spending; poor returns on capital reflective of the physical limitations of the Western Canadian Sedimentary Basin; high capital and operating costs; and a high royalty burden imposed by provincial governments. The consequences of low profitability include inadequate returns to equity investors, a drop in spending on upstream services such as drilling and exploration, a reduced ability of the industry to generate employment, and an adverse effect on the economy of Alberta. Forecasts indicate that the upstream sector is extremely vulnerable to a scenario of relatively flat prices due to high and increasing operating costs and depletion charges, and the significant royalty payments that still are in effect. Little scope is foreseen for industry profitability to return to acceptable levels over the first half of the 1990s. Reduced royalties have the potential to make a significant contribution to improved profitability. 52 figs., 40 tabs

    In 1956, Africanized bees began to spread in the American continent from southern Brazil, where original African bees mated with European bees. A few years later, in 1990, these Africanized bees reached the United States and were found in Texas. Currently, these hybrid bees are found in several North American states and will probably reach the Canadian border in the future. Although the presence of Africanized bees had produced positive effects on Brazilian economy, including improvement in crop pollination and in honey production, turning Brazil into a major exporter, the negative impacts-such as swarming, aggressive behavior, and the ability to mass attack-resulted in serious and fatal envenomation with humans and animals. Victims of bee attacks usually develop a severe envenomation syndrome characterized by the release of a large amount of cytokines [interleukins (IL) IL-1, IL-6, IL-8], and tumor necrosis factor (TNF). Subsequently, such cytokines produce an acute inflammatory response that triggers adverse effects on skeletal muscles; bone marrow; hepatic and renal functions; and cardiovascular, central nervous, and immune systems. Finally, the aim of the present review is to study historical characteristics and current status of Africanized bees' spread, the composition of their venom, the impact of the bees on the Brazilian economy and ecology, and clinical aspects of their stings including immune response, and to suggest a protocol for bee sting management since there is no safe and effective antivenom available.

  17. Why New Hybrid Organizations are Formed: Historical Perspectives on Epistemic and Academic Drift.

    Science.gov (United States)

    Kaiserfeld, Thomas

    2013-06-01

    By comparing three types of hybrid organizations-18th-century scientific academies, 19th-century institutions of higher vocational education, and 20th-century industrial research institutes-it is the purpose here to answer the question of why new hybrid organizations are continuously formed. Traditionally, and often implicitly, it is often assumed that emerging groups of potential knowledge users have their own organizational preferences and demands influencing the setup of new hybrid organizations. By applying the concepts epistemic and academic drift, it will be argued here, however, that internal organizational dynamics are just as important as changing historical conjunctures in the uses of science when understanding why new hybrid organizations are formed. Only seldom have older hybrid organizations sought to make themselves relevant to new categories of knowledge users as the original ones have been marginalized. Instead, they have tended to accede to ideals supported by traditional academic organizations with higher status in terms of knowledge management, primarily universities. Through this process, demand has been generated for the founding of new hybrid organizations rather than the transformation of existing ones. Although this study focuses on Swedish cases, it is argued that since Sweden strove consistently to implement existing international policy trends during the periods in question, the observations may be generalized to apply to other national and transnational contexts.

    Following more than a century of cocaine hydrochloride extraction from Erythroxylon coca, this drug remains representing a serious social and public health problema around the world. This paper intends to provide a review about the cocaine theme, focusing on historical background and on its different neurotransmission systems, as well as addresses therapeutics aspects about drug addiction. Electronic search in databases Medline, Pubmed and Lilacs was accomplished in order to select classics and recent studies relevant to the discussion of issue addressed. Previous studies have shown high vulnerability to relapse to cocaine seeking following prolonged withdrawal periods. Such behavioral consequences have been cre-dited to induced changes in brain neurotransmitters provoked by repeated cocaine use. In recent years, the growing abuse of this drug has mobilized researchers worldwide in seeking for new therapies that reduce the behavioral and neurochemical changes resulting from addiction. Numerous advances regarding the treatment of cocaine abuse and dependence have emerged in recent years. However, researche aiming at a safe and effective users' pharmacological treatment remain necessary and should be continued.

    Tennis federations are regularly faced with decisions regarding which athletes should be supported in financial terms, and for how long. The financial investments can be considerable, given the cost of competing on tour has been estimated at a minimum $121,000 per year and only the top 130 professionally ranked athletes earned enough prize money to cover this cost in 2012. This study investigates key points of progression in tennis players' careers, to determine how these have changed over time and how that evolution may inform talent development. Approximately 400,000 weekly rankings for 273 male professional tennis players between 1985 and 2010 were compiled, and historical trends in the time taken to reach career milestones were investigated by least-squares regression. The time between earning a first professional ranking point and entry into the Top 100 significantly increased over time for all considered athletes. This was at the detriment of time spent within the Top 100 for some athletes. Career peak Top 50-100 athletes have shown an increase in longevity. These results assist tennis federations in assessing the progress of developing athletes and highlight the evolving nature of the competition for top players.

    Although psychology has become a female-dominated field, this pattern of gender representation has not held true within the specialty of neuropsychology. In recent years more women have been pursuing careers in neuropsychology, and while the balance of male and female neuropsychologists as a whole has shifted, it is unclear whether the gender composition of leadership has also changed. Our goal was to survey various neuropsychological organizations, training programs, editorial boards, and organizations granting board certification to determine the current gender composition of leadership positions within neuropsychology. A literature review was conducted to examine past trends of gender composition in neuropsychology, psychology, medicine, and academia. Data on current gender compositions of the field were culled from publicly available websites and through personal communication with representatives from major psychological and neuropsychological organizations. We found that the overall composition of the field has changed over time, but notable gender disparities in leadership positions remain. Women still comprise the minority of leadership positions within most neuropsychological organizations, editorial boards for neuropsychology journals, and fellow positions in major neuropsychological organizations. More equitable representation has been achieved in the directorships of training programs and ABPP/ABCN board certification. We review the historical trends in gender discrepancies in leadership in neuropsychology and discuss these within the broader arenas of academia, research, and medicine. We conclude with a summary addressing potential causes for these discrepancies, including work-life balance issues, discrimination, institutional bias, and various other factors. We also provide pragmatic suggestions to help address these continued disparities.

    In the course of time, electrocardiography has assumed several modalities with varying electrode numbers, electrode positions and lead systems. 12-lead electrocardiography and 3-lead vectorcardiography have become particularly popular. These modalities developed in parallel through the mid-twentieth century. In the same time interval, the physical concepts underlying electrocardiography were defined and worked out. In particular, the vector concept (heart vector, lead vector, volume conductor) appeared to be essential to understanding the manifestations of electrical heart activity, both in the 12-lead electrocardiogram (ECG) and in the 3-lead vectorcardiogram (VCG). Not universally appreciated in the clinic, the vectorcardiogram, and with it the vector concept, went out of use. A revival of vectorcardiography started in the 90's, when VCGs were mathematically synthesized from standard 12-lead ECGs. This facilitated combined electrocardiography and vectorcardiography without the need for a special recording system. This paper gives an overview of these historical developments, elaborates on the vector concept and seeks to define where VCG analysis/interpretation can add diagnostic/prognostic value to conventional 12-lead ECG analysis.

    2018-05-01

    We historically trace various non-conventional explanations for the origin of the cosmic microwave background and discuss their merit, while analyzing the dynamics of their rejection, as well as the relevant physical and methodological reasons for it. It turns out that there have been many such unorthodox interpretations; not only those developed in the context of theories rejecting the relativistic ("Big Bang") paradigm entirely (e.g., by Alfvén, Hoyle and Narlikar) but also those coming from the camp of original thinkers firmly entrenched in the relativistic milieu (e.g., by Rees, Ellis, Rowan-Robinson, Layzer and Hively). In fact, the orthodox interpretation has only incrementally won out against the alternatives over the course of the three decades of its multi-stage development. While on the whole, none of the alternatives to the hot Big Bang scenario is persuasive today, we discuss the epistemic ramifications of establishing orthodoxy and eliminating alternatives in science, an issue recently discussed by philosophers and historians of science for other areas of physics. Finally, we single out some plausible and possibly fruitful ideas offered by the alternatives.

    2011-01-01

    Advances over the last fifteen years have made social network analysis (SNA) a powerful tool for the study of nonhuman primate social behavior. Although many SNA-based techniques have been only very recently adopted in primatological research, others have been commonly used by primatologists for decades. The roots of SNA also stem from some of the same conceptual frameworks as the majority of nonhuman primate behavioral research. The rapid development of SNA in recent years has led to questions within the primatological community of where and how SNA fits within this field. We aim to address these questions by providing an overview of the historical relationship between SNA and the study of nonhuman primates. We begin with a brief history of the development of SNA, followed by a detailed description of the network-based visualization techniques, analytical methods and conceptual frameworks which have been employed by primatologists since as early as the 1960s. We also introduce some of the latest advances to SNA, thereby demonstrating that this approach contains novel tools for study of nonhuman primate social behavior which may be used to shed light on questions that cannot be addressed fully using more conventional methods.

    2017-04-01

    We aim to review the historical evolution that has led to the study of the brain (body)-mind relationship based on brain oscillations, to outline and illustrate the principles of neuro-oscillatory dynamics using research findings. The paper addresses the relevant developments in behavioral sciences after Wundt established the science of psychology, and developments in the neurosciences after alpha and gamma oscillations were discovered by Berger and Adrian, respectively. Basic neuroscientific studies have led to a number of principles: (1) spontaneous EEG is composed of a set of oscillatory components, (2) the brain responds with oscillatory activity, (3) poststimulus oscillatory activity is a function of prestimulus activity, (4) the brain response results from a superposition of oscillatory components, (5) there are multiplicities with regard to oscillations and functions, and (6) oscillations are spatially integrated. Findings of clinical studies suggest that oscillatory responses can serve as biomarkers for neuropsychiatric disorders. However, the field of psychology is still making limited use of neuro-oscillatory dynamics for a bio-behavioral understanding of cognitive-affective processes. Copyright © 2016 Elsevier Ltd.

    2014-07-01

    Full Text Available The development of mental health services in the Eastern Cape Province is inextricably entwined in South Africa’s colonial history and the racist policy of apartheid. Prior to the development of mental hospitals, mental health services were provided through a network of public and mission hospitals. This paper explores the development of early hospital and mental health services in the Eastern Cape from the time of the Cape Colony to the dissolution of apartheid in 1994, and highlights the influence of colonialism, race and legislation in the development of mental health services in this province. The objective is to provide a background of mental health services in order to identify the historical factors that have had an impact on the current shortcomings in the provision of public sector mental health services in the province. This information will assist in the future planning and development of a new service for the province without the stigma of the past. This research indicates that one lesson from the past should be the equitable distribution of resources for the provision of care for all that inhabit this province, as enshrined in South Africa’s constitution.

    2014-06-01

    Contributing to the optimisation of drinking-water supplies is a key responsibility for professional hydrogeologists. Thus, it is interesting to look back and put current-day practices in the framework of historic evolution and past achievements. The water supply of Bruges (Belgium), with an innovative supply system already established by the end of the 13th century, forms an interesting case study. The supply system consisted of an underground network of pipes feeding public and private wells. A special construction, the Water House, was built to overcome a topographical height difference. Population growth and industrial expansion during the 19th century increased the water demand and new solutions were necessary. Tap water became available from 1925 onwards and, as a stopgap measure to meet demand, deep groundwater was used. This invoked a lively debate among the city council, scientists and entrepreneurs, whereby both water quality and quantity were discussed. Although based on a lack of modern understanding of the groundwater system, some arguments, both pro or contra, look very familiar to current-day hydrogeologists.

  7. Historical and contemporary perspectives on children's diets: is choice always in the patients' best interest?

    On 29 March 1744, Thomasin Grace, a 13-year-old girl, was the first inpatient admitted to the Northampton General Infirmary (later the Northampton General Hospital). Inpatient hospital diets, then and now, are mainstays of effective patient treatment. In the mid-18th century there were four prescribed diets at Northampton: 'full', 'milk', 'dry' and 'low'. Previous opinions concerning these four diets were unfavourable, but had not been based upon an individual dietetic assessment. Thomasin would most likely have been given the milk diet, but use of the full diet cannot be excluded. 'Grace Everyman' is Thomasin's modern equivalent. Under current NHS guidelines Thomasin would be considered a paediatric patient, but in 1744 she would have been considered as an adult. This study undertakes a full dietetic analysis of all the prescribed diets available for Thomasin in 1744 and compares this against random choices for Grace from the 2009 inpatient menu from the paediatric (Paddington) ward, and the adult ward inpatient menu at the Northampton General Hospital. The results show that, for Thomasin, the 1744 milk and full diets met the current advised nutritional requirements for adequate dietary intake. However, for Grace, the present 2009 Paddington and adult ward menu, although generally meeting nutritional requirements, could, if Grace or her carer consistently chose poorly during a prolonged inpatient stay, lead to inadequate nutrition. This challenges assumptions that hospital diets were historically inadequate, and that choice in present day equates with satisfactory nutritional intake.

  8. Baculovirus Insecticides in Latin America: Historical Overview, Current Status and Future Perspectives

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Baculoviruses are known to regulate many insect populations in nature. Their host-specificity is very high, usually restricted to a single or a few closely related insect species. They are amongst the safest pesticides, with no or negligible effects on non-target organisms, including beneficial insects, vertebrates and plants. Baculovirus-based pesticides are compatible with integrated pest management strategies and the expansion of their application will significantly reduce the risks associated with the use of synthetic chemical insecticides. Several successful baculovirus-based pest control programs have taken place in Latin American countries. Sustainable agriculture (a trend promoted by state authorities in most Latin American countries will benefit from the wider use of registered viral pesticides and new viral products that are in the process of registration and others in the applied research pipeline. The success of baculovirus-based control programs depends upon collaborative efforts among government and research institutions, growers associations, and private companies, which realize the importance of using strategies that protect human health and the environment at large. Initiatives to develop new regulations that promote the use of this type of ecological alternatives tailored to different local conditions and farming systems are underway.

  9. A Historical Perspective on Local Environmental Movements in Japan: Lessons for the Transdisciplinary Approach on Water Resource Governance

    Science.gov (United States)

    Oh, T.

    2014-12-01

    Typical studies on natural resources from a social science perspective tend to choose one type of resource—water, for example— and ask what factors contribute to the sustainable use or wasteful exploitation of that resource. However, climate change and economic development, which are causing increased pressure on local resources and presenting communities with increased levels of tradeoffs and potential conflicts, force us to consider the trade-offs between options for using a particular resource. Therefore, the transdisciplinary approach that accurately captures the advantages and disadvantages of various possible resource uses is particularly important in the complex social-ecological systems, where concerns about inequality with respect to resource use and access have become unavoidable. Needless to say, resource management and policy require sound scientific understanding of the complex interconnections between nature and society, however, in contrast to typical international discussions, I discuss Japan not as an "advanced" case where various dilemmas have been successfully addressed by the government through the optimal use of technology, but rather as a nation seeing an emerging trend that is based on a awareness of the connections between local resources and the environment. Furthermore, from a historical viewpoint, the nexus of local resources is not a brand-new idea in the experience of environmental governance in Japan. There exist the local environment movements, which emphasized the interconnection of local resources and succeeded in urging the governmental action and policymaking. For this reason, local movements and local knowledge for the resource governance warrant attention. This study focuses on the historical cases relevant to water resource management including groundwater, and considers the contexts and conditions to holistically address local resource problems, paying particular attention to interactions between science and society.

  11. Using historical perspective in designing discovery learning on Integral for undergraduate students

    Abadi; Fiangga, S.

    2018-01-01

    In the course of Integral Calculus, to be able to calculate an integral of a given function is becoming the main idea in the teaching beside the ability in implementing the application of integral. The students tend to be unable to understand the conceptual idea of what is integration actually. One of the promising perspectives that can be used to invite students to discover the idea of integral is the History and Pedagogy Mathematics (HPM). The method of exhaustion and indivisible appear in the discussion on the early history of area measurement. This paper study will discuss the designed learning activities based on the method of exhaustion and indivisible in providing the undergraduate student’s discovery materials for integral using design research. The designed learning activities were conducted into design experiment that consists of three phases, i.e., preliminary, design experimental, and teaching experiment. The teaching experiment phase was conducted in two cycles for refinement purpose. The finding suggests that the implementation of the method of exhaustion and indivisible enable students to reinvent the idea of integral by using the concept of derivative.

  12. A free church perspective on military chaplains role in its historical context

    2016-12-01

    Full Text Available The waning influence of Christianity in the United Kingdom’s armed forces since 1960 and the growing ignorance of personnel who have ties to a particular denomination, gave rise to a new assessment of the military chaplain in a modern and postmodern context. This article gives an overview of the practice during the two world wars and after the 1960s. It also gives an overview of the debate on the current role of the military chaplain, especially the beliefs of Herspring, Zahn, Coleman and McCormack, and eventually set up a role model from a Free Church perspective. It is shown that an operating model that is only defined in pastoral terms does not satisfy. The pastoral and spiritual definition, in terms of a liminal serving as an alternative, is suggested because it frees the chaplain to act more independent and also describes the best practice that has always prevailed in the British army.

    Tick-borne diseases (TBDs) remain to be a global animal health threat. Developing countries like the Philippines is not exempt to this. Despite the potential impact TBDs can give to these countries, local government initiatives and researches remain to be limited. In the Philippines, most epidemiological studies were confined only to specific areas, and predominantly in the Northern Area. Due to its unique geography and limited studies, the current nationwide status of most TBDs could not be clearly established. This review mainly covered published studies and presented challenges in the conduct of TBD research in the Philippines, which may be similar to other Southeast Asian or developing countries. To date, reported livestock TBD pathogens in the Philippines include Anaplasma, Babesia, Theileria, and Mycoplasma spp. With the ubiquitous presence of the Rhipicephalus microplus ticks in the country, it is highly probable that other pathogens transmitted by these vectors could be present. Despite studies on different TBDs in the livestock sector, the Philippine government has not yet heightened its efforts to implement tick control measures as part of the routine animal health program for local farmers. Further studies might be needed to determine the nationwide prevalence of TBDs and the presence of other possible tick species and TBD pathogens. The Philippine scenario may present situations that are similar to other developing countries. Copyright © 2017 Elsevier B.V. All rights reserved.

  14. Supply/Demand in Radiology: A Historical Perspective and Comparison to other Labor Markets.

    There has been attention on the job market recently and on radiology's supply/demand calculus. Supply is influenced by the number of trained radiologists, while demand is driven by demographics and technological innovation. We analyze the supply of radiologists historically and compare to other labor markets-medical and non-medical, domestic and foreign. We review National Resident Matching Program data in radiology and several other specialties from 1991 to 2015. We also review surveys, physician recruitment data, and peer-reviewed commentaries on medical specialty job markets. Trends are compared across specialties. The regulation of American medical training is compared to that in the United Kingdom and to a nonmedical labor market, unionized theatrical stage employees. Radiology residency positions have increased since 1998 despite a downturn in the job market. This expansion coincides with a decreasing percentage of positions filled by domestic graduates. A similar trend has been seen in pathology, a notoriously oversupplied specialty. Conversely, other specialties have maintained their proportion of domestic graduates by way of limited supply or implicit demand. The radiology job market is currently oversupplied, primarily a result of increasing residency positions despite indicators of decreasing demand. The percentage of residency positions filled by domestic graduates has decreased during the same period, suggesting that medical student interest is responsive to the market. Other specialties, particularly pathology, demonstrate the dangers of chronic oversupply. We advocate a reduction of radiology residency positions such that supply closely approximates demand without exceeding it. Additional measures may be taken, if necessary, to restore market equilibrium in the event of a mild undersupply. Copyright © 2015 The Association of University Radiologists.

    During the past three decades, improvements in the treatment of childhood leukemia have resulted in high cure rates, particularly for acute lymphoblastic leukemia (ALL). Unfortunately, successful therapy has come with a price, as significant morbidity can result from neurological affects which harm the brain and spinal cord. The expectation and hope is that chemotherapy, as a primary means of CNS therapy, will result in acceptable disease control with less CNS morbidity than has been observed with combinations of chemotherapy and radiotherapy over the past several decades. In this review we discuss the poignant, historical aspects of CNS leukemia therapy, outline current methods of systemic and CNS leukemia therapy, and present imaging findings we have encountered in childhood leukemia patients with a variety of acute neurological conditions. A major objective of our research is to understand the neuroimaging correlates of acute and chronic effects of cancer and therapy. Specific features related to CNS leukemia and associated short-term toxicities, both disease- and therapy-related, are emphasized in this review with the specific neuroimaging findings. Specific CNS findings are similarly important when treating acute myelogenous leukemia (AML), and details of leukemic involvement and toxicities are also presented in this entity. Despite contemporary treatment approaches which favor the use of chemotherapy (including intrathecal therapy) over radiotherapy in the treatment of CNS leukemia, children still occasionally experience morbid neurotoxicity. Standard neuroimaging is sufficient to identify a variety of neurotoxic sequelae in children, and often suggest specific etiologies. Specific neuroimaging findings frequently indicate a need to alter antileukemia therapy. It is important to appreciate that intrathecal and high doses of systemic chemotherapy are not innocuous and are associated with acute, specific, recognizable, and often serious neurological

  16. Skyscape of an Amazonian Diaspora: Arawak Astronomy in Historical Comparative Perspective

    Science.gov (United States)

    Jara, Fabiola

    The title of this article "Arawak Astronomy" suggests that the research matter concerns the astronomy of an already well-defined ethnographic entity. This however does not do justice to the complexities of Arawak (pre)history. This contribution aims to discuss and connect the available historical and ethnographic data on Arawak astronomies as gathered by the author (Jara 2000), with the most recent research on the archeology and comparative linguistics of the Arawak diaspora. The article argues that Arawak astronomy has to be related to the cultural and sociopolitical continuities and discontinuities of the Arawak diaspora throughout the lowlands of tropical South America. This article recognizes the need to consider Arawak astronomy has an object to be discovered and explained within its local and regional contexts. Notwithstanding these remarks, based on a sustained examination of ethnohistorical and ethnographic sources, this article proposes that Arawak astronomy can be characterized by at least four elements: firstly, a horizon system of observation which combines the observation of the solar solstices and equinoxes with the near heliacal and near cosmic rising or setting of at least seven star groups - the Pleiades, the Hyades, the upper stars of the constellation of Scorpius (including α Sco), Corvus, the Belt of Orion, several stars near Sirius, and the Milky Way. Secondly, the association of the rising and setting of these star groups with the seasonal cycle, mainly with the start and/or of the end of rainy and dry seasons. Thirdly, the widespread association of the stars of the year (most commonly the Pleiades but sometimes Orion or the head of Scorpius) with the beginning of the agricultural cycle and consequently with the end of the heavy rains announcing the time to plant the new fields. The last and fourth commonality are the inscriptions or markings of the origin of the stars in the local landscape, lakes, mountains, and other salient landscape

    Soil organic carbon (SOC) management is key for soil fertility and for mitigation and adaptation to climate change, particularly in desertification-prone areas such as Mediterranean croplands. Industrialization and global change processes affect SOC dynamics in multiple, often opposing, ways. Here we present a detailed SOC balance in Spanish cropland from 1900 to 2008, as a model of a Mediterranean, industrialized agriculture. Net Primary Productivity (NPP) and soil C inputs were estimated based on yield and management data. Changes in SOC stocks were modeled using HSOC, a simple model with one inert and two active C pools, which combines RothC model parameters with humification coefficients. Crop yields increased by 227% during the studied period, but total C exported from the agroecosystem only increased by 73%, total NPP by 30%, and soil C inputs by 20%. There was a continued decline in SOC during the 20th century, and cropland SOC levels in 2008 were 17% below their 1933 peak. SOC trends were driven by historical changes in land uses, management practices and climate. Cropland expansion was the main driver of SOC loss until mid-20th century, followed by the decline in soil C inputs during the fast agricultural industrialization starting in the 1950s, which reduced harvest indices and weed biomass production, particularly in woody cropping systems. C inputs started recovering in the 1980s, mainly through increasing crop residue return. The upward trend in SOC mineralization rates was an increasingly important driver of SOC losses, triggered by irrigation expansion, soil cover loss and climate change-driven temperature rise.

  19. Territorial Contradictions of the Rise of China: Geopolitics, Nationalism and Hegemony in Comparative-Historical Perspective

    Directory of Open Access Journals (Sweden)

    Sahan Savas Karatasli

    2017-02-01

    Full Text Available There is debate in the literature regarding whether China can become a new world hegemonic power in the 21st century. Most existing analyses focus on economic aspects of world hegemony-building processes and ignore its macro-political dimensions. This article starts with the premise that reshaping the geopolitical configuration of the inter-state system is an important part of world hegemony-building processes. One of the ways in which previous and current world hegemonic powers established their world hegemonies was through the inclusion of new nations by co-opting, supporting or sometimes selectively leading a section of nationalist movements into independence. Our comparative analysis shows that, as of now, contemporary China has not been following this historical pattern. Compared to Mao-era China, which was perceived as a champion of national liberation—at least when colonial and semi-colonial areas were at stake—today’s People’s Republic of China (PRC is emerging as a champion of the global geo-political status quo. The current Chinese government is not actively pursuing the transformation of the inter-state system or seeking to create instabilities at different levels. This is because, unlike previous and current world hegemonic powers, during its rise to global preeminence, Chinese territorial integrity has been challenged due to rapid escalation of nationalist/secessionist movements within its own state boundaries. Hence, the PRC's foreign policy has consistently been concerned with creating and preserving macro-political stability at national and international levels.

  20. Sulfate Salts in Gasoline and Ethanol Fuels -- Historical Perspective and Analysis of Available Data

    This report reviews the chemistry of sulfate salts dissolved in ethanol and gasoline, potential sources of sulfate salts in ethanol and gasoline, the history of consumer vehicle issues with sulfate salt deposits in the early 2000s, and the corresponding changes to the denatured fuel ethanol specification. Recommendations for future research are provided. During a period of rapid market expansion in 2004-05, issues were reported with vehicles running on E10 provided by certain suppliers in some markets. It was commonly believed that these vehicle problems were caused by sulfate salts precipitating from the fuel. Investigators identified sodium sulfate, and in one case also ammonium sulfate, as the predominate salts found in the engines. Several stakeholders believed the issue was excess sulfate ions in the ethanol portion of the E10, and in 2005 the ASTM specification for ethanol (D4806) was modified to include a 4-part per million (ppm) limit on sulfate ions. While there have been no further reports of consumer vehicle issues, the recently approved increase of ethanol in gasoline from 10 to 15 volume percent has resulted in renewed interest in the sulfate ion concentration in fuel ethanol. This report reviews published data on the solubility of sulfate salts in ethanol. The possible sources of sulfate anions and charge balancing cations (such as sodium) in fuel ethanol and petroleum derived blendstocks are discussed. Examination of historical information on the consumer vehicle issues that occurred in 2004-2005 reveals that a source of sodium or ammonium ions, required for the formation of the observed insoluble salts, was never identified. Recommendations for research to better understand sulfate salt solubility issues in ethanol, hydrocarbon blendstocks, and ethanol-gasoline blends are presented.

    Estrogens play a critical role in many aspects of physiology, particularly female reproductive function, but also in pathophysiology, and are associated with protection from numerous diseases in premenopausal women. Steroids and the effects of estrogen have been known for ∼90 years, with the first evidence for a receptor for estrogen presented ∼50 years ago. The original ancestral steroid receptor, extending back into evolution more than 500 million years, was likely an estrogen receptor, whereas G protein-coupled receptors (GPCRs) trace their origins back into history more than one billion years. The classical estrogen receptors (ERα and ERβ) are ligand-activated transcription factors that confer estrogen sensitivity upon many genes. It was soon apparent that these, or novel receptors may also be responsible for the "rapid"/"non-genomic" membrane-associated effects of estrogen. The identification of an orphan GPCR (GPR30, published in 1996) opened a new field of research with the description in 2000 that GPR30 expression is required for rapid estrogen signaling. In 2005-2006, the field was greatly stimulated by two studies that described the binding of estrogen to GPR30-expressing cell membranes, followed by the identification of a GPR30-selective agonist (that lacked binding and activity towards ERα and ERβ). Renamed GPER (G protein-coupled estrogen receptor) by IUPHAR in 2007, the total number of articles in PubMed related to this receptor recently surpassed 1000. In this article, the authors present personal perspectives on how they became involved in the discovery and/or advancement of GPER research. These areas include non-genomic effects on vascular tone, receptor cloning, molecular and cellular biology, signal transduction mechanisms and pharmacology of GPER, highlighting the roles of GPER and GPER-selective compounds in diseases such as obesity, diabetes, and cancer and the obligatory role of GPER in propagating cardiovascular aging, arterial

  2. Energy use in the U.S. steel industry: a historical perspective and future opportunities

    The U.S. steel industry has taken enormous strides over the past decades to reduce its energy consumption; since the end of World War II, the industry has reduced its energy intensity (energy use per shipped ton) by 60 percent. Between 1990 and 1998 alone, intensity has dropped from 20 to 18 million Btu (MBtu) per ton. This figure is projected to decrease to 15 MBtu/ton by 2010 with an asymptotic trend towards 14 MBtu/ton. Domestic shipments are projected to flatten out over the next decade to around 105 million tons which means that total energy consumption will also decrease. Historically, the steel industry has accounted for about 6 percent of U.S. energy consumption. Today, that figure is less than 2 percent and will decrease further to 1.5 percent by 2010. The primary causes for the decrease in energy consumption since WWII are: The use of pellets in the blast furnace and the application of new technology in the ironmaking process to further reduce fuel rates per net ton of hot metal (NTHM); The total replacement of the open hearth process by basic oxygen and electric furnaces; The almost total replacement of ingot casting by continuous casting (which improved yield dramatically and thus reduced the tons of raw steel required per ton of shipments); and The growth of the electric furnace sector of the industry at the expense of hot metal-based processes (which has also stimulated scrap recycling so that about 55 percent of ''new'' steel is now melted from scrap steel). This report focuses on the concept of good practices (i.e., those that are sustainable and can use today's technology). If all the industry could operate on this basis, the additional savings per ton could total 2 MBtu, As further restructuring occurs and the swing from hot metal-based to electric furnace-based production continues, the average consumption will approach the good practice energy per ton. Further savings will accrue through new technology, particularly in

    Glaucoma management is challenging to patients as well as to the eye care providers. The study is aimed at describing the challenges faced by providers using qualitative methods. In-depth interviews were conducted with selected Ophthalmologists and resident doctors in ophthalmology at centres offering medical and surgical glaucoma services in Lagos state, Nigeria, according to established qualitative methods. This was done using semi-structured, open ended questions to explore the providers' perspective on glaucoma burden, challenges in the management, surgery for glaucoma, acceptance of glaucoma surgery by patients, and recommendations for improving glaucoma services. The discussions were recorded with the aid of a micro-cassette recorder. Familiarisation was done to identify key ideas in the data, then, the main themes and sub-themes were identified. Quotes that reflect the themes and sub-themes were then identified in the data. In-depth interviews were conducted with a total of 11 ophthalmologists and resident doctors in training. Majority were of the opinion that glaucoma is a significant burden constituting about 35% of outpatient visits. Identified patient related challenges include; late presentation, lack of glaucoma awareness, delay in referral from optometrists, and poor compliance with medications. Shortages in needed equipment were also identified. Availability, affordability and counterfeiting of drugs were the major challenges related to medical treatment. Majority of the participants agreed that surgery should be offered to the patients as soon as the diagnosis of glaucoma is made. However, continuous monitoring of the patient on medical treatment is another line of option for them in early cases; if they are convinced the patients will be compliant. Some respondents considered the current number of glaucoma surgeries as adequate, while some think otherwise. Reasons put forward for reluctance to offer glaucoma surgery include; late presentation, lack

    We examine in depth the effect of differences in the smoking adoption patterns of men and women on the mortality gender gap in Netherlands, employing a historical perspective. Using an indirect estimation technique based on observed lung cancer mortality from 1931 to 2012, we estimated lifetime smoking prevalence and smoking-attributable mortality. We decomposed the sex difference in life expectancy at birth into smoking-related and nonsmoking-related overall and cause-specific mortality. The smoking epidemic in Netherlands, which started among men born around 1850 and among women from birth cohort 1900 onwards, contributed substantially to the increasing sex difference in life expectancy at birth from 1931 (1.3 years) to 1982 (6.7 years), the subsequent decline to 3.7 years in 2012, and the high excess mortality among Dutch men born between 1895 and 1910. Smoking-related cancer mortality contributed most to the increase in the sex difference, whereas smoking-related cardiovascular disease mortality was mainly responsible for the decline from 1983 onwards. Examining nonsmoking-related (cause-specific) mortality shed new light on the mortality gender gap and revealed the important role of smoking-related cancers, the continuation of excess mortality among women aged 40–50, and a smaller role of biological factors in the sex difference than was previously estimated.

    Fukushima Daiichi Accident occurred in March 11, 2011 was of highest interest in the world and had been reported worldwide from relevant Japanese organizations almost in real time just after happened. This article overviewed five month's response of government and energy related organization of each country and international agency and summarized effects of the accident on nuclear power in energy policy of each country as well as perspective of nuclear industry responded to change of market trend. After the accident, basic policy to regard nuclear power as important was maintained with enhancing reactor safety against extreme events in countries choosing nuclear power as important and requisite energy and there appeared such a trend of nuclear power phase-out in countries promoting nuclear power prudently. Choice of nuclear power would be decided on energy state of each country and was not affected before and after the accident. Trend of nuclear business was closely related with that of market and no fundamental change was observed although some industries with revenue from business in nuclear power phase-out country or cancelled project after the accident were obliged to be affected.

    Food waste (FW) related issues in developing countries is currently considered to be a major threatening factor for sustainable development and FW management systems. Due to incomplete FW management systems, many developing countries are facing challenges, such as environmental and sanitary problems that are caused by FW. The difference in FW generation trends between developing countries and developed countries was reviewed in this work, which demonstrated that the effects of income level, population growth, and public participation in FW management are very important. Thus, this work aimed to provide an overview of recycling activities, related regulations, and current FW treatment technology in developing countries by following some case studies. Taiwan, has been suggested as being a successful case in terms of FW management, and is therefore a typical model for developing countries to follow. Finally, an integrative management system as a suitable model for FW management has been suggested for developing countries. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The African Organization for Research and Training in Cancer (aortic) is a bilingual (English and French) nonprofit organization dedicated to the promotion of cancer control and palliation in Africa. Its mission in respect to cancer control in Africa includes support of research and training;provision of relevant and accurate information on the prevention, early diagnosis, treatment, and palliation of cancer;promotion of public awareness about cancer and reduction of the stigma associated with it.In seeking to achieve its goal of cancer control in Africa, aortic strives to unite the continent and to make a positive impact throughout the region by collaboration with health ministries and global cancer organizations. The organization's key objectives are to further research relating to cancers prevalent in Africa, to support training programs in oncology for health care workers, to deal with the challenges of creating cancer control and prevention programs, and to raise public awareness of cancer in Africa. It also plans to organize symposia, workshops, meetings, and conferences that support its mission.Founded in September 1982, aortic was active only between 1983 (when its inaugural conference was held in the City of Lome, Togo, West Africa) and the late 1980s. The organization subsequently became inactive and moribund. In 2000, a group of expatriate African physicians and scientists joined in an effort with their non-African friends and colleagues to reactivate the dormant organization. Since its reactivation, aortic has succeeded in putting cancer on the public health agenda in many African countries by highlighting Africa's urgent need for cancer control and by holding meetings every two years in various African cities. National and international cancer control organizations worldwide have recognized the challenges facing Africa and have joined in aortic's mission.

  10. The role of private organisations in welfare work. The historical perspective.

    1992-06-01

    The Danish welfare measures originated in private initiatives. From the end of the last century, welfare activities have developed through private relief organisations and with support from the State, local governments, and counties. Since the 1960s, many institutions which had been built up by private relief organisations were actually taken over by local governments or counties. By way of illustration, the development of EGV DaneCare (the Danish Association for the Care of the Elderly), from its origin as a voluntary relief organisation based on voluntary work and collected funds, is described. From 1910, EGV was the pioneer within the field of, for example, old people's homes, winter shelters, and holidays in the country for elderly people. In the 1960s, EGV became a professional service organisation which assisted the local governments in developing a wide range of variegated offers within the work for elderly people. Assistance offered to the local governments became the organisation's principal project up to the 1980s. The population's confidence in the ability of the public authorities to cope with the social tasks was at the time undermined by increasing scepticism. That was why EGV founded the DaneAge Association, which soon became a national cause with more than 200,000 members. The DaneAge Association operates as an association independent of the public authorities pursuing both local and national policies concerning the elderly and implementing humanitarian initiatives based on voluntary work. Studies made by the DaneAge Association show, among other things, that 20 per cent of the people aged 60 and over need practical assistance.(ABSTRACT TRUNCATED AT 250 WORDS)

Accession to the EU by the central and eastern European countries requires that the countries accept the acquis communautaire (the rules of the EU) as well as the acquis politique (the political aims of the EU), including environmental issues. Accession to the EU is expected to result in substantial environmental improvements both in the central and eastern European countries and in the countries which are exposed to pollution originating from these countries. The extent of the environmental improvements when the 10 countries implement and use the rules laid down by the EU is an important issue. Another important approximation related problem is how the countries will secure the human and financial resources to meet the EU requirements. The purpose of this publication is to provide a first analysis of the tasks ahead in the environmental field during the current approximation process, including the environmental consequences/gains and the costs of accession of the 10 associated countries to the EU. This analysis deals both with general and sectoral problems, focusing on sectors with special adaptation problems which thus need targeted assistance. The analysed sectors are: air pollution, ozone depleting substances, waste, water pollution, agriculture, chemical substances, biodiversity, energy - including nuclear energy. (LN) 119 refs

In the middle of the Cold War, scientists from competing countries had a unique chance to meet and share their research ideas. This peaceful collaboration resulted in 1961 signing of the Antarctic Treaty, protecting the sixth continent for scientific, non-military research. Many AGU scientists indicate that the IGY educational programs, along with the rapid development of science and technology following the IGY inspired their career choice.

    2011-01-01

    In the offshoring literature, there is a huge disconnect between the alternative modes of organizing offshore production and their relative welfare impact on a host country. We bridge this gap by comparing the welfare of a host country from vertical foreign direct investment (VFDI) vis-a-vis international outsourcing. Our model finds that the ability to maximize welfare in the alternative modes of organizing offshore production is contingent on the absorptive capacity of the host country. If ...

    Full Text Available Abstract Background Following the World Health Organization Forum in November 2007, the Beijing Declaration recognized the importance of food safety along with the rights of all individuals to a safe and adequate diet. The aim of this study is to retrospectively analyze the patterns in food alert and recall by countries to identify the principal hazard generators and gatekeepers of food safety in the eleven months leading up to the Declaration. Methods The food recall data set was collected by the Laboratory of the Government Chemist (LGC, UK over the period from January to November 2007. Statistics were computed with the focus reporting patterns by the 117 countries. The complexity of the recorded interrelations was depicted as a network constructed from structural properties contained in the data. The analysed network properties included degrees, weighted degrees, modularity and k-core decomposition. Network analyses of the reports, based on 'country making report' (detector and 'country reported on' (transgressor, revealed that the network is organized around a dominant core. Results Ten countries were reported for sixty per cent of all faulty products marketed, with the top 5 countries having received between 100 to 281 reports. Further analysis of the dominant core revealed that out of the top five transgressors three made no reports (in the order China > Turkey > Iran. The top ten detectors account for three quarters of reports with three > 300 (Italy: 406, Germany: 340, United Kingdom: 322. Conclusion Of the 117 countries studied, the vast majority of food reports are made by 10 countries, with EU countries predominating. The majority of the faulty foodstuffs originate in ten countries with four major producers making no reports. This pattern is very distant from that proposed by the Beijing Declaration which urges all countries to take responsibility for the provision of safe and adequate diets for their nationals.

    Full Text Available Meuleman and Billiet (2009 have carried out a simulation study aimed at the question how many countries are needed for accurate multilevel SEM estimation in comparative studies. The authors concluded that a sample of 50 to 100 countries is needed for accurate estimation. Recently, Bayesian estimation methods have been introduced in structural equation modeling which should work well with much lower sample sizes. The current study reanalyzes the simulation of Meuleman and Billiet using Bayesian estimation to find the lowest number of countries needed when conducting multilevel SEM. The main result of our simulations is that a sample of about 20 countries is sufficient for accurate Bayesian estimation, which makes multilevel SEM practicable for the number of countries commonly available in large scale comparative surveys.

    European countries of nuclear power phase-out have changed to commit to the future of nuclear energy due to the intended low-carbon power, the energy security concerns and the need of replacement reactors as current reactors approach the end of operating lives, as Italian government has passed legislation to build new nuclear power plants. This article described the perspective of nuclear power policy changes in UK, Italy an Sweden and the business trend and the SWOT analysis of related electric utilities (EDF, Enel and Vattenfall) and nuclear industries (Areva NP, Sheffield Forgemasters, ENSA and Studsvik). Policy implications obtained from this analysis were commented for Japanese nuclear industry activities. (T. Tanaka)

    2017-07-01

    Colour vision is a complex visual function that can be affected by congenital and/or acquired disorders. The frequency of congenital colour vision deficiencies has been investigated in rail and navy staff since the 1870s. Various test methods have been developed. Wool tests, flor contrast tests and colour plate tests have been used. A published colour plate test, based on Stilling's pseudo-isochromatic plates in combination with a flor contrast test, has been a common screening method for colour vision testing in German-speaking countries. This test is intended to detect congenital and acquired colour vision deficiencies in a simple and safe manner. More modern options, such as Internet and tablet PC have technical limitations, but will increasingly be used for screening for colour vision deficiencies.

    Full Text Available This article proposes the study of sustainable development in the use of renewable resources by emerging countries. It is noted that the financing of projects and policies related to renewable energy is moving from developed countries to emerging nations. Studies indicate that it will take more targeted investments to fuel production area and power generation, which can set a problem for developing countries, since they do not have sufficient resources to diversify and expand their energy matrixes. The deductive method was adopted based on exploratory research.

  4. An Investigation of the Influence of the Worldwide Governance and Competitiveness on Accounting Fraud Cases: A Cross-Country Perspective

    Directory of Open Access Journals (Sweden)

    Rabeea Sadaf

    2018-02-01

    Full Text Available This article examines how worldwide governance, global competiveness, and other institutional determinants have influenced the number of accounting fraud cases in several countries. The researchers have focused more closely on the importance of ‘good governance’ as one of the indicators of development objectives in itself. The institutional perspective is employed to explain the complexity of frauds in different societies which can be compatible for the purposes of international judgments in order to increase the effectiveness of previous forensic accounting theories. In this paper, a linear regression model is tested where governance, competitiveness, and other institutional variables are associated with a measure of accounting fraud cases. From our results, we can merely claim that an increased level of controlled corruption and political stability might reduce the number of fraud cases in various countries, while more effective and independent governance services with a higher freedom of expression seemed to increase them. The existence of accounting crimes also appeared to be a suitable proxy of better competitiveness. Anglo-Saxon countries have more stated fraud cases than other countries, attributed, perhaps, to the finest commercial courts with the most professional and least corrupt judges in the world, with centuries of precedent cases and experience in dealing with fraud. Moreover, we believe that a better understanding of fraud detection is a potentially important element in forensic accounting analytics in the success of governance policies to enhance development and reduce the risk of bankruptcies related to the reported fraud cases of enterprises.

    2010-02-15

    The paper focuses on opportunities and risks presented by second-generation biofuels technologies in eight case study countries: Brazil, Cameroon, China, India, Mexico, South Africa, Tanzania and Thailand. The report begins by exploring the state of the art of second-generation technologies and their production, followed by projections of future demand and a discussion of drivers of that demand. The report then delves into various feedstock options and the global potential for bioenergy production. The final chapter offers a look at the potential for sustainable second-generation biofuel production in developing countries including considerations of economic, social and environmental impacts. Key findings of the report include that: second-generation biofuels produced from agricultural and forestry residues can play a crucial role in the transport sector without competing with food production; the potential for second-generation biofuels should be mobilized in emerging and developing countries where a large share of global residues is produced; less-developed countries will first need to invest in agricultural production and infrastructure in order to improve the framework conditions for the production of second-generation biofuels; financial barriers to production exist in many developing countries; and the suitability of second-generation biofuels against individual developing countries' needs should be evaluated.

Nonetheless, by 2009 nearly three-quarters of its structure corresponded to fossil fuels, with most of the countries being net importers of these fuels. This situation marks the region´s dependence on the effects of changes in energy commodities. Therefore, the opportunity lies in higher use of renewable energy sources that contribute to the country´s energy security and represent significant environmental benefits. The purpose of this paper is to provide a comparative analysis of current energy scenarios of six Latin American countries (Mexico, Honduras, Nicaragua, Brazil, Ecuador and Chile in order to evaluate the policies, programs and strategies implemented in the search for greater participation of renewable energy. Considering the importance of the water-energy nexus that could serve to promote renewables under conditions of water scarcity, a qualitative data comparison was accomplished, considering energy consumption, CO2 emissions, GDP and water withdrawals per country. The authors conclude that, despite technological and financial constraints, all the involved countries are moving towards the substitution of a fossil fuel based matrix to a renewable one. This process could be seen as a result of clear policies and strategies that have been set, which include (but are not limited to price regulations setting, preferential prices to electricity generated through renewable energy technologies and incentives formulated to encourage the production of biofuels.

    Full Text Available This paper contributes to the research on organizational culture (OC from a crosscountry perspective. From the economic point of view we see that society today has led us to increasing international cooperation and globalization. Despite the opening of economic borders there are still limits to consider when operating across national boundaries. One of those limits can be associated with culture – the way things are commonly understood and accepted in different national entities. This can be of special importance for small countries, as they need to adjust to their larger counterparts in order to be economically competitive. Research focuses on different aspects when studying OC, but it is generally agreed that task orientation and interpersonal relationships become important dimensions when we analyze this phenomenon. In order to understand OC and to measure it in cross cultural settings, a universal measurement tool is needed; however, drafting such a tool has for some time been a sticky task. In this paper the measurement invariance of the Organizational Culture Questionnaire (Vadi et al. 2002 is examined by comparing the data from seven countries representing Eastern and Western Europe, Russia, and China. This sample covers both small and large countries. A confirmative factor analysis was used as a means to test measurement invariance across the selected samples. In addition, Multidimensional Scaling technique was applied to provide a visual representation of the data. An analysis was carried out using the statistical software SPSS/AMOS 17.0. The results indicate that task orientation can be found as a common dimension whereas relationship orientation seems to hold a diverse meaning across countries. Instead of relationship orientation, a dimension reflecting negative employee emotions towards the organization was detected. It also turned out that the strength of the relationship between the obtained subscales shows interesting variation

    Full Text Available Peptides have been studied for over 100 years, but for most of this time the focus was on a specific peptide or peptides, and not on the general peptidome of a biological sample. In the 1990s, mass spectrometry techniques were developed for the analysis of proteins, usually after digestion into peptides. The field of peptidomics started soon after proteomics and has grown to over 600 publications that use the word “peptidomic” or “peptidomics”. Although peptidomics is related to proteomics, there are fundamental differences. In this review, we discuss these differences along with the history of the field of peptidomics.

    2016-03-01

    The costs of health care place developing countries under enormous economic pressure. Latin America is a region characterized by wide ethnic and per capita gross domestic product variations among different countries. Chronic kidney failure prevalence and incidence, as well as provision of renal replacement therapy (RRT), have increased in all Latin American countries over the last 20 years. From an ethical point of view, life-sustaining therapies such as RRT should be available to all patients with chronic kidney disease who might benefit. However, even among Latin American countries with similar per capita incomes and health care expenditures, only some have been able to achieve universal access to RRT. This indicates that it is not just a problem of wealth or distribution of scarce health care resources, but one of social justice. Strategies to increase the availability of RRT and renal palliative-supportive care, as well as implementation of interventions to prevent chronic kidney disease development and progression, are needed in Latin America and other developing countries.

    Full Text Available There is a lack of knowledge about the state of affairs of the trauma treatments in Europe. To start to fill in this gap, key persons from seven European countries—Georgia, Germany, Lithuania, the Netherlands, Poland, Switzerland, and Turkey—accepted the invitation to give their expert opinion on the state of affairs in their country at an invited panel discussion at the XIV 2015 ESTSS Conference in Vilnius, Lithuania. Brief reports from the seven countries reveal significant diversities among different European countries in terms of awareness of health problems related to trauma, the availability of trauma treatments, and treatment approaches. Political and economic differences across the European countries contribute to the diversities in the developments of trauma treatments. European national psychotrauma societies are active in establishing training curricula and dissemination of trauma-focused treatments. Despite the growing acknowledgment of trauma and dissemination of trauma-focused treatments, there is a lack of Europe-wide policies to ensure availability of trauma treatment in Europe for trauma survivors. The need for more detailed analysis of trauma treatment in all European countries and development of European-level trauma-informed health care policies is outlined.

  16. Globalisations in a nutshell: Historical perspectives on the changing governance of the shea commodity chain in northern Ghana

    Directory of Open Access Journals (Sweden)

    Andrew Wardell

    2013-08-01

    Full Text Available Pre-colonial patterns of trade in West Africa included exchanges of shea in periodic local and regional markets. The collection, processing and marketing of shea products in such markets continues to be predominantly by women to both meet subsistence needs, and exchange of surpluses. In the early part of the 20th century, the British colonial administration considered the possibilities of starting large-scale exports of shea kernels to Europe. Multiple colonial initiatives to develop the global trade were not successful due to a composite of factors. Contemporary patterns of production, trade and regulation are contrasted in the context of globalisation in the post-independence era. The government of Ghana has progressively reinforced its ambitions to expand the shea nut trade as part of the state’s portfolio of major non-traditional agricultural export commodities. This policy is embedded within the (now dominant orthodoxy of neo-liberalism, which privileges monetized production systems and private over public regulation. Historically and culturally-embedded patterns of shea production and trade by women in northern Ghana may now be challenged by the emergence of new processing technologies, the emergence of an oligopolistic global commodity chain and the anticipated continued growth in global demand for cocoa butter equivalents.  Nevertheless, the cumulative impacts of increasing commercialisation and world market integration at the national and local level in Ghana, and other West African producer countries, are still unknown. There are risks, however, that this process may result in social differentiation, changes in household consumption patterns and loss of livelihoods, particularly for women.

  18. What Prevents Quality Midwifery Care? A Systematic Mapping of Barriers in Low and Middle Income Countries from the Provider Perspective.

    Directory of Open Access Journals (Sweden)

    Alex Filby

    Full Text Available Quality of care is essential for further progress in reducing maternal and newborn deaths. The integration of educated, trained, regulated and licensed midwives into the health system is associated with improved quality of care and sustained decreases in maternal and newborn mortality. To date, research on barriers to quality of care for women and newborns has not given due attention to the care provider's perspective. This paper addresses this gap by presenting the findings of a systematic mapping of the literature of the social, economic and professional barriers preventing midwifery personnel in low and middle income countries (LMICs from providing quality of care.A systematic search of five electronic databases for literature published between January 1990 and August 2013. Eligible items included published and unpublished items in all languages. Items were screened against inclusion and exclusion criteria, yielding 82 items from 34 countries. 44% discussed countries or regions in Africa, 38% in Asia, and 5% in the Americas. Nearly half the articles were published since 2011. Data was extracted and presented in a narrative synthesis and tables. Items were organized into three categories; social; economic and professional barriers, based on an analytical framework. Barriers connected to the socially and culturally constructed context of childbirth, although least reported, appear instrumental in preventing quality midwifery care.Significant social and cultural, economic and professional barriers can prevent the provision of quality midwifery care in LMICs. An analytical framework is proposed to show how the overlaps between the barriers reinforce each other, and that they arise from gender inequality. Links are made between burn out and moral distress, caused by the barriers, and poor quality care. Ongoing mechanisms to improve quality care will need to address the barriers from the midwifery provider perspective, as well as the underlying

    2017-08-03

    As part of the ActifCare (ACcess to Timely Formal Care) project, we conducted expert interviews in eight European countries with policy and political decision makers, or representatives of relevant institutions, to determine their perspectives on access to formal care for people with dementia and their carers. Each ActifCare country (Germany, Ireland, Italy, The Netherlands, Norway, Portugal, Sweden, United Kingdom) conducted semi-structured interviews with 4-7 experts (total N = 38). The interview guide addressed the topics "Complexity and Continuity of Care", "Formal Services", and "Public Awareness". Country-specific analysis of interview transcripts used an inductive qualitative content analysis. Cross-national synthesis focused on similarities in themes across the ActifCare countries. The analysis revealed ten common themes and two additional sub-themes across countries. Among others, the experts highlighted the need for a coordinating role and the necessity of information to address issues of complexity and continuity of care, demanded person-centred, tailored, and multidisciplinary formal services, and referred to education, mass media and campaigns as means to raise public awareness. Policy and political decision makers appear well acquainted with current discussions among both researchers and practitioners of possible approaches to improve access to dementia care. Experts described pragmatic, realistic strategies to influence dementia care. Suggested innovations concerned how to achieve improved dementia care, rather than transforming the nature of the services provided. Knowledge gained in these expert interviews may be useful to national decision makers when they consider reshaping the organisation of dementia care, and may thus help to develop best-practice strategies and recommendations.

    Hessel, L

    2009-08-01

    Cervical cancer and other diseases related to human papillomavirus (HPV) represent a global public health problem. Safe and effective vaccines are now available and already used in many industrialized countries. Immunization offers the best hope for protecting the population against a disease that is the second most deadly cancer in the developing world and the first most deadly in Africa. The World Health Organization currently recommends introduction of HVP vaccination in developing countries. Widespread vaccination could be beneficial in numerous domains other than primary prevention of cervical cancer. Efforts to overcome the numerous obstacles and speed up implementation of HVP vaccination programs are now underway in many areas ranging from related scientific issues such as epidemiology and clinical research to administrative concerns such as healthcare economics, vaccination guidelines, public acceptation, program funding, and universal access. Vaccine manufacturers have committed themselves to working in partnership with national and international organizations to ensure access to HPV vaccine for all countries regardless of economic level, Although numerous issues must be resolved to optimize the use of HPV vaccines and ensure synergistic integration of vaccination, screening and treatment, current initiatives and efforts should allow introduction of HPV vaccination in developing countries in a not too distant future.

  1. Antibiotic resistance in the food chain: A developing country-perspective

    2016-11-01

    Full Text Available Antibiotics are now endangered species facing extinction due to the worldwide emergence of antibiotic resistance (ABR. Food animals are considered as key reservoirs of antibiotic-resistant bacteria with the use of antibiotics in the food production industry having contributed to the actual global challenge of ABR. There are no geographic boundaries to impede the worldwide spread of ABR. If preventive and containment measures are not applied locally, nationally and regionally, the limited interventions in one country, continent and for instance, in the developing world, could compromise the efficacy and endanger ABR containment policies implemented in other parts of the world, the best-managed high-resource countries included.

    Full Text Available Nowadays, the migration of active labour force is a phenomenon with a rapid dynamics, generated mainly by globalization. The international migration is appreciated to imply about 200 million persons, which is double than 25 years ago. .The migration is determined by economical, social and political causes. .The migration of active labour force in Romania registered in the Community Countries reaches low levels, about 200.000 person, but the illegal one is appreciated to reach 1.7-2 milion persons. The effects of migration are mainly due to: the loss of the tax payer – active labour force formed in Romania, the weakening of the social solidarity in the social security system, and in the same time, its increase in the destination countries , the remittance of some important amounts of money in the origin countries, the contact with other economical, social, cultural models. The evolution of remittance in the world is very dynamic, in 2007 it is said to be about 250 billion dollars ,from which 7,1 billion euro for our country, compared to 9,1 billion euro representing direct investments.

    Antibiotics are now "endangered species" facing extinction due to the worldwide emergence of antibiotic resistance (ABR). Food animals are considered as key reservoirs of antibiotic-resistant bacteria with the use of antibiotics in the food production industry having contributed to the actual global challenge of ABR. There are no geographic boundaries to impede the worldwide spread of ABR. If preventive and containment measures are not applied locally, nationally and regionally, the limited interventions in one country, continent and for instance, in the developing world, could compromise the efficacy and endanger ABR containment policies implemented in other parts of the world, the best-managed high-resource countries included. Multifaceted, comprehensive, and integrated measures complying with the One Health approach are imperative to ensure food safety and security, effectively combat infectious diseases, curb the emergence and spread of ABR, and preserve the efficacy of antibiotics for future generations. Countries should follow the World Health Organization, World Organization for Animal Health, and the Food and Agriculture Organization of the United Nations recommendations to implement national action plans encompassing human, (food) animal, and environmental sectors to improve policies, interventions and activities that address the prevention and containment of ABR from farm-to-fork. This review covers (i) the origin of antibiotic resistance, (ii) pathways by which bacteria spread to humans from farm-to-fork, (iii) differences in levels of antibiotic resistance between developed and developing countries, and (iv) prevention and containment measures of antibiotic resistance in the food chain.

    Vaccines are a key contributor to public health, especially in developing countries. Despite numerous demonstrations of the cost-effectiveness of immunisation, vaccines spending accounted for only 1.7% of the total pharmaceutical market in 2002, when UNICEF estimated that 34 million children were not reached by routine immunisation, most of them in developing countries. Several international organizations or initiatives, like the Global Alliance for Vaccines and Immunisation (GAVI), have defined a long-term goal of universal immunisation in developing countries. There is an urgent need to estimate the financial resources required to meet this goal. The objective of this study was to anticipate the funding needs for childhood immunisation in developing countries over the 2004-2014 period. The study scope includes all the 75 countries eligible for support from GAVI, and covers existing vaccines that are considered as a priority for GAVI (DTP (diphtheria, tetanus, pertussis), hepatitis B, Haemophilus influenzae type b (as a stand alone presentation or in combination with DTP) and yellow fever) as well as future vaccines (meningitis A and C, rotavirus, human papilloma virus (HPV), malaria, Streptococcus pneumoniae and tuberculosis) likely to be available within the 10-year period. We developed a methodology to estimate the number of doses required, based on disease prevalence and incidence, target populations, introduction dates of new vaccines, coverage dynamics and dosing regimen. The introduction price and price evolution of vaccines over time were modelled, taking into account the type of vaccine, the expected return on investment from vaccine manufacturers and the competitive landscape. Non-vaccine costs (capital costs and non-vaccine recurrent costs) were estimated based on the number of people immunised and number of doses dispensed, using available case studies as a reference. According to the optimal scenario that would consider the provision of all vaccines

    The radionuclide applications are continuously escalation in nuclear medicine. Especially, the development of positron emission tomography (PET) technique has increased very rapidly the use of short-lived radioisotopes in this field, and this has caused the development of compact medical cyclotrons. About 30 cyclotrons operated in the world wide are actually found in the developing countries. In parallel of this progress, the basic nuclear sciences, especially nuclear chemistry and radiopharmaceutical chemistry will probably very important fields in the next new century for nuclear science and technology applications in health care sector. For this reason, the developing countries should eventually revise their academic educational and training programs aiming to ensure the formation of qualified basic nuclear scientists such as nuclear chemist, nuclear physicist, radiopharmacist, etc. (author)

  10. LABOUR SUBCONTRACTING IN THE CONSTRUCTION INDUSTRIES OF DEVELOPING COUNTRIES: AN ASSESSMENT FROM TWO PERSPECTIVES

    Directory of Open Access Journals (Sweden)

    Jill Wells

    2006-06-01

    Full Text Available The practice of employing labour through subcontractors (often referred to as the ‘outsourcing’ of labour is both long established and widespread in the construction industries of developing countries. Recent studies show that it is also increasing in both developing and developed countries. An assessment of the advantages of the practice from the viewpoint of the contractors and of the labour force, suggests it is unlikely to disappear. The paper goes on to explore the implications for the development of the construction industry, as well as for the welfare of the workers and the achievement of broader development objectives. It is concluded that interventions may be needed to deal with some of the negative repercussions, but they have to accept and build on current labour practices.

    2006-11-01

    Full Text Available Abstract Cervical cancer is the seventh most frequent cancer worldwide but more than 80% of cases occur in developing countries. Till date, radiation therapy with external beam and brachytherapy remains as the core treatment for most stages of cervical cancer. However, radiation treatment protocols and equipment modelled on the best developed countries can be seldom applied directly to developing countries owing to financial constraints and lack of qualified personnel, thus, a substantial proportion of patients do not have access to even palliative radiation therapy. Treatment options when the standard therapy is either not available or difficult to reproduce in particular settings is highly desirable with the potential to save lives that otherwise could be lost by the lack of adequate treatment. These options of treatment ideally had to have show, 1 that these are not inferior to the "standard" in terms of either survival or quality of life; 2 that these can be delivered in settings were the "standard" is not available or if available its quality is poor; and 3 that the treatment option be accepted by the population to be treated. Based on these considerations, it is obvious that cervical cancer patients, particularly those who live in countries with limited resources and therefore may not have sufficient radiation therapy resources are in need of newer therapeutical options. There is now a considerable amount of information emanating from clinical studies where surgery has a major role in treating this disease. These forms of "radiation-sparing" treatments include total mesometrial resection that could make unnecessary the use of adjuvant radiation; neoadjuvant chemotherapy that could avoid the use of adjuvant radiation in around 85% of patients and preoperative chemoradiation that could make brachytherapy dispensable. The feasibility and therapeutical value of these potential forms of management need to be prospectively evaluated.

    Directory of Open Access Journals (Sweden)

    Roxana Maria Grecu

    2011-06-01

    Full Text Available The strategies for structural-systemic crisis management have generated, to a geographical level, a number of differences between EU countries. These cleavages are the result of differentialmacroeconomic policies. In this context, this article has the aim of achieving a comparative approach between countries of the south, west and east of the EU space. Also our approach is focused on observing the nature of macroeconomic policies and also on identifying a "pattern" associated with a common ideal -type of "rational choice" in the efficient and effective management of systemic crises. This article aims to identify areas of growth and economic stability of a particular model of public policy and political-economic ideology, to set up a mechanism for "economic engineering”. From the methodological point of view, this article uses a quantitativemethodology, derived from mathematical analysis, statistics and stochastic, in order to explain, understand and predict the possible evolution of the systemic crises in the EU countries. The interest lies in the possibility of giving a model of macroeconomic policy for the adjustment of inflationist imbalances, labor market and pricepolicy, and also in regulating the equation of production-consumption.

    Arsenic concentrations above acceptable standards for drinking water have been detected in many countries and this should therefore is a global issue. The presence of arsenic in subsurface aquifers and drinking water systems is a potentially serious human health hazard. The current population growth in Pakistan and other developing countries will have direct bearing on the water sector for meeting the domestic, industrial and agricultural needs. Pakistan is about to exhaust its available water resources and is on the verge of becoming a water deficit country. Water pollution is a serious menace in Pakistan, as almost 70% of its surface waters as well as its groundwater reserves have contaminated by biological, organic and inorganic pollutants. In some areas of Pakistan, a number of shallow aquifers and tube wells are contaminated with arsenic at levels which are above the recommended USEPA arsenic level of 10 ppb (10 microg L(-1)). Adverse health effects including human mortality from drinking water are well documented and can be attributed to arsenic contamination. The present paper reviews appropriate and low cost methods for the elimination of arsenic from drinking waters. It is recommended that a combination of low cost chemical treatment like ion exchange, filtration and adsorption along with bioremediation may be useful option for arsenic removal from drinking water.

    Assessing trade in health services (TiHS) in developing countries is challenging since the sources of information are diverse, information is not accessible and professionals lack grasp of issues. A multi-country study was conducted in the Eastern Mediterranean Region (EMR)--Egypt, Jordan, Lebanon, Morocco, Oman, Pakistan, Sudan, Syrian Arab Republic, Tunisia, and Yemen. The objective was to estimate the direction, volume, and value of TiHS; analyze country commitments; and assess the challenges and opportunities for health services.Trade liberalization favored an open trade regime and encouraged foreign direct investment. Consumption abroad and movement of natural persons were the two prevalent modes. Yemen and Sudan are net importers, while Jordan promotes health tourism. In 2002, Yemenis spent US$ 80 million out of pocket for treatment abroad, while Jordan generated US$ 620 million. Egypt, Pakistan, Sudan and Tunisia export health workers, while Oman relies on import and 40% of its workforce is non-Omani. There is a general lack of coherence between Ministries of Trade and Health in formulating policies on TiHS.This is the first organized attempt to look at TiHS in the EMR. The systematic approach has helped create greater awareness, and a move towards better policy coherence in the area of trade in health services. Copyright (c) 2009 John Wiley & Sons, Ltd.

    2002-12-01

    Australia is a significant livestock producer and a major exporter of livestock, livestock products and livestock genetic material. An outbreak of foot and mouth disease (FMD) would have severe economic consequences on the economy. A recent study found that in an outbreak lasting six months, real gross domestic product in Australia would fall by an estimated 0.6% (AUS$3.5 billion), employment by 0.8%, and a depreciation of 3% would be recorded in the exchange rate in the first year. Much of this impact would be due to the loss of export markets. Given the significant consequences of an outbreak of FMD, Australia invests considerable resources in prevention and planning. These measures can be viewed at three levels, namely: pre-border, border and post-border. Australia recently further enhanced quarantine at the border to minimise the risk of entry of FMD. However, no matter how much is invested, there is no guarantee that FMD will not enter the country. Accordingly, it is important to ensure that comprehensive contingency plans are also in place. Recent outbreaks in previously free countries have shown that a large outbreak of FMD poses major problems for the animal health services of a country and a combined government and industry response is required.

    2016-07-01

    Full Text Available This paper tries to encompass the effects that modern industrialization of East European countries has one the working population over the age of 50. Policies and procedures that multinational corporations have proved to be difficult to follow for the ageing population in Romania; the fact that western companies have introduced specific procedures on performance appraisal and organizational development is proven to be hard to understand and follow by the ageing population of Romania. One of the core topics of the paper discusses the effects that different cultural perspectives-between Western corporations and the human capital from East European countries- may have on the ageing workforce. The fact that Western corporations are becoming an important presence in Romania’s national economy can cause major social problems for workers over the age of 50 because of the aforementioned cultural differences. Western companies generally have specific working methodologies which need to be internalized by their personnel. Considering the fact that Romania is mainly an ageing country, Western corporations depend on workers over the age of 50. In this regard, foreign companies need to adapt their training programs and general working procedures for them to be understood by workers that are accustomed to other organizational systems.As mentioned in the paper, unemployment rate remains constant for workers over the age of 50, but their performance declines compared to other age categories. This aspect shows that, even if workers over the age of 50 manage to keep their current position in a Western company, they do not excel in their tasks, relying heavily on cultural values that companies may enlist, like the promotion of retirement from the company.Adapting Romania’s ageing workforce to the standards of multinational corporations represents a key element in obtaining sustainable growth and encouraging companies to locate an operational branch in the

    Energy access has been singled out by the AGECC in 2010 as one of the important problems to be tackled in the next few decades in a world where 1.3 billion people do not have access to electricity and 2.7 use primitive fuels – mainly fuel wood – for cooking and heating. To solve such problems, innumerous small scale projects have been implemented around the world either on the improvement of cooking stoves, biogas and others, as well as in generating electricity in decentralized systems. We discuss here the “large scale approach” to solve these problems in Brazil through the introduction of LPG (liquid petroleum gas) in Brazil 70 years ago, all over the country, as a cooking fuel that replaced significantly the use of fuel wood in rural areas. In addition to that, we describe the governmental program (Luz para Todos – LPT – Light for all) introduced more recently to extend the electricity grid to around 10 million people, reducing considerably the number of people without access to electricity in the rural areas of the country. Such experiences and the corresponding lessons learned could be replicated in other developing countries, contributing significantly to poverty alleviation. - Highlights: • Energy access is one important problem for 1.3 billion people not having access to electricity and 2.7 billion using primitive fuels for cooking-heating. • We discuss the approach introduced in Brazil through the introduction of LPG as a cooking fuel that replaced significantly the use of fuel wood in rural areas. • We describe the program introduced to supply electricity, reducing the number of people without access to electricity in rural areas. • Lessons learned could be replicated in other DCs, contributing to poverty alleviation

The decision to migrate, the rate of saving while abroad, as well as the length of a migrant's stay in the foreign country, are all viewed as part of a solution to an intertemporal optimization problem. In addition to studying the microeconomic aspects of temporary migration, the paper analyses the determinants of the equilibrium flow of migrants, the corresponding domestic wage, and the level of welfare enjoyed by a typical worker. Effects of an emigration tax are also investigated." excerpt

    Pandey, M; Mathew, A; Nair, M K

    1999-08-01

    Over the past 50 years, a dominant role of tobacco smoking in lung cancer causation has been demonstrated. Almost three-quarters of the lung cancer cases can be attributed to tobacco smoking. The global variation in lung cancer incidence is thought to be directly proportional to the smoking habits prevalent in that part of the world. Lung cancer shows a greater upward trend in incidence in the USA, in central and Eastern Europe than ever before, especially in females. Japan too has recorded a 10-fold increase in incidence in both sexes since 1975. In India the problem is further compounded by absence of authentic data on time trend. The recent trend of available data suggests a more or less linear trend. At present lung cancer ranks among the top three killers in men in almost every metropolis in India. The highest incidence rate has been recorded in Bombay (14.6/ 100,000) and the lowest in Barshi (2.0/100,000). How much of these can be attributed to smoking cannot be commented on as no case-control or cohort studies have ever been undertaken in India. The situation is more alarming in other developing countries, where there is no authentic data on tobacco use or lung cancer incidences. The relationship between tobacco and cancer is both simple and complex. The majority of the cancer patients are smokers, while the cancer incidence is not proportional among smokers. To explain this, various factors such as type of smoke, duration of smoke, amount of carcinogens, presence of activation and metabolism pathways, and lately genetic environment interaction, have been put forward. It appears that the relationship is more complex than at first thought. In developing countries, it is further compounded by lack of data on usage and dependence of the economies of these countries on tobacco. The situation is alarming, with ever-increasing incidence among women and non-smokers exposed to smoke (passive smokers). Tobacco use has already become an epidemic.

The prevalence of chronic kidney disease has been predicted to grow the fastest in low- to middle-income countries (LMICs. There is evidence that people living in LMICs have the highest need for renal replacement therapy (RRT despite the lowest access to various modalities of treatment. As continuous ambulatory peritoneal dialysis (CAPD does not require advanced technologies, much infrastructure, or need for dialysis staff support, it should be an ideal form of RRT in LMICs, particularly for those living in remote areas. However, CAPD is scarcely available in many LMICs, and even where available, there are several hurdles to be confronted regarding patient selection for this modality. High cost of CAPD due to unavailability of fluids, low patient education and motivation, low remuneration for nephrologists, lack of expertise/experience for catheter insertion and management of complications, presence of associated comorbid diseases, and various socio-demographic factors contribute significantly toward reduced patient selection for CAPD. Cost of CAPD fluids seems to be a major constraint given that many countries do not have the capacity to manufacture fluids but instead rely heavily on fluids imported from developed countries. There is need to invest in fluid manufacturing (either nationally or

    Human exploitation of sea turtles in Venezuela dates back at least 800 years and continues to the present day. The first concerns about the status of sea turtle populations arose in the 1970s, and the projects from this early era were a tagging program, beach evaluation and in situ nest protection. Since then, efforts to develop a sea turtle research and conservation sector in Venezuela have resulted in a number of successes and rather more failures. Among the achievements is a course 'Sea Turtle Biology and Conservation Techniques', which has now been run for 15 years and has educated several hundred participants and enabled the establishment of a valuable professional network, and the publication of the Venezuelan 'Sea Turtle Recovery Action Plan' in 2000. But Venezuela shares with other developing countries some crucial shortcomings which have restricted the success of conservation and research efforts. Whilst regulations relating to protected areas and natural resource use have proliferated, enforcement is weak. Community-based projects and environmental education programs exist, but levels of participation are low. A large number of conservation approaches have been applied, including head-starting and nest translocation to hatcheries, but their value as conservation tools remains unproven. Research has increased, but its impact on decision-making is not significant. Taking an insider's perspective on the challenges to date in sea turtle research and conservation in Venezuela reveals much about the reality facing conservation scientists in developing countries and the forces that shape and can potentially derail research and conservation efforts

    Misattributed paternity or 'false' paternity is when a man is wrongly thought, by himself and possibly by others, to be the biological father of a child. Nowadays, because of the progression of genetics and genomics the possibility of finding misattributed paternity during familial genetic testing has increased. In contrast to other medical information, which pertains primarily to individuals, information obtained by genetic testing and/or pedigree analysis necessarily has implications for other biologically related members in the family. Disclosing or not a misattributed paternity has a number of different biological and social consequences for the people involved. Such an issue presents important ethical and deontological challenges. The debate centres on whether or not to inform the family and, particularly, whom in the family, about the possibility that misattributed paternity might be discovered incidentally, and whether or not it is the duty of the healthcare professional (HCP) to disclose the results and to whom. In this paper, we consider the different perspectives and reported problems, and analyse their cultural, ethical and legal dimensions. We compare the position of HCPs from an Italian and British point of view, particularly their role in genetic counselling. We discuss whether the Oviedo Convention of the Council of Europe (1997) can be seen as a basis for enriching the debate.

    This scoping review explores circumstances surrounding the decision about, and eventual experience of, transitioning older adults into alternative levels of housing (ALH), such as long-term care. This topic is examined from a family member perspective, given their exposure and involvement in the care of older adult relatives during this transitional period. The scoping review methodology is based on the framework of Arksey and O'Malley and subsequent recommendations from Levac, Colquhoun, and O'Brien. Approximately 470 articles were reviewed covering the period between 2000 and November 2014; 37 articles met inclusion criteria. A temporal organization of themes was used to describe the experiences of family members in the pretransition, active transition, and posttransition periods of moving older adult relatives into ALH. This paper highlights the transitional period as a time of crisis, with a lack of planning, support, and transparent discussion. This study identifies a need for future research on the potential benefits of family support groups, interim transitional housing options, different models of ALH, changing roles in the posttransition period, and the need for a comprehensive list of housing options for older adults. Results have the potential to inform policy/practice and improve the lives of older adults and their family.

  12. Understanding HMIS Implementation in a Developing Country Ministry of Health Context - an Institutional Logics Perspective.

    2012-01-01

    Globally, health management information systems (HMIS) have been hailed as important tools for health reform (1). However, their implementation has become a major challenge for researchers and practitioners because of the significant proportion of failure of implementation efforts (2; 3). Researchers have attributed this significant failure of HMIS implementation, in part, to the complexity of meeting with and satisfying multiple (poorly understood) logics in the implementation process. This paper focuses on exploring the multiple logics, including how they may conflict and affect the HMIS implementation process. Particularly, I draw on an institutional logics perspective to analyze empirical findings from an action research project, which involved HMIS implementation in a state government Ministry of Health in (Northern) Nigeria. The analysis highlights the important HMIS institutional logics, where they conflict and how they are resolved. I argue for an expanded understanding of HMIS implementation that recognizes various institutional logics that participants bring to the implementation process, and how these are inscribed in the decision making process in ways that may be conflicting, and increasing the risk of failure. Furthermore, I propose that the resolution of conflicting logics can be conceptualized as involving deinstitutionalization, changeover resolution or dialectical resolution mechanisms. I conclude by suggesting that HMIS implementation can be improved by implementation strategies that are made based on an understanding of these conflicting logics.

    2010-01-01

    This paper offers a critical look at how energy security-, food and agriculture-, and climate change-oriented international organizations frame biomass energy production in developing countries, in particular, ethanol production in Brazil. Using the world-economy system as a theoretical lens, the paper raises a concern as to whether the way these global institutions frame bioenergy's role in developing regions manifests energy and ecological inequalities between the core and the periphery, as well as creates internal contradictions that perpetuate unequal exchange embedded in the system. Simultaneously, these organizations frame Brazil as a semi-peripheral state that, while successful in finding a niche concurring with the core's demand for cheap energy and cost-effective decarbonization strategies, is not necessarily a suitable role model for the periphery's socio-economic development.

    The primary Varicella Zoster Virus (VZV) infection results in varicella, a generally benign, self-limiting disease in immunocompetent children. Despite the usual course a possible fatal evolution of the primary infection is observed predominantly in immunocompromised subjects and in adults, especially emigrating from tropical regions. Two cases of fatal varicella have been investigated and discussed. Death occurred in two patients over 40 years of age, coming from South Asia and receiving chronic immunosuppressive therapy. The forensic expert must be cautious and consider all clinical records in managing fatal varicella cases, bearing in mind risk factors and pre-existing conditions such as age, geographical provenance and pathological comorbidity, which may lead to a bad prognosis irrespective of therapies. Based on the severe and fatal course observed in the reported cases, an extension of the immunization program appears advisable for immigrants from tropical countries, especially before scheduled immunotherapy.

  15. Cultural perspectives in cancer care: impact of Islamic traditions and practices in Middle Eastern countries.

    Science.gov (United States)

    Silbermann, Michael; Hassan, Esmat A

    2011-10-01

    People's attitudes to cancer and its treatment are influenced by the patient's and his family's faith, beliefs, societal traditions, and cultural taboos and stigmatism. In most Middle Eastern countries Islam is the dominant religion, yet there are differences as to people's acceptance of cancer, starting with the realization of the diagnosis and the subsequent treatment planning. In many societies in the Middle East, patients prefer that their families will be the first to know about the disease and to agree to the planned treatment protocols. Whereas in Western societies the patient is usually the first to know, understand, and agree to the proposed therapeutic procedures; this is not the case in various Muslim societies. Health care professionals have to accept these kinds of practices and find ways to cope with their patients' sensitivities, thereby preserving their dignity and faith.

    2009-01-01

    This cross-sectional multi-centre study explored how family members and friends of illicit drug users perceived protective and risk factors, treatment facilities and policies and laws regarding illicit drug use. Family members and friends of illicit drug users were recruited in 10 urban health care outpatient units in 7 Latin American countries (Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Honduras and Mexico) to complete a questionnaire. The majority of the respondents chose psycho-social factors over genetic or biological explanations as causes of drug problems. Respondents felt that families and governments were responsible for preventing drug problems. Church/religious institutions were most often mentioned in the context of accessible treatment. When asked about access to treatment facilities, the majority said that there were not enough. Shame about drug use, cost, and limited treatment options were most often cited as barriers to treatment.

    Full Text Available The advent of the Internet continues to open new frontiers in digital marketing. One visible impact of the Internet in marketing has been the growing increase in online transactions which profits marketers and seemingly satisfies customers. However, in developing countries, the potential of online shopping has not been fully explored, and in some cases, are just non-existent. Lack of online infrastructure has often been attributed to the slower growth in online transactions in Africa, however, the customers’ preparedness and inclination to use the service is ignored. .Against this backdrop, this study seeks to analyze consumers’ propensity to engage in online transactions with a focus on demographic attributes such as age, gender and education. Using customers in Ghana as a case study, key reasons as well as the demographics that fancy online transactions are revealed. The results indicate that delivery problems, poor internet connection, privacy and security issues are some of the reasons preventing customers to shop online

  18. Internalising externalities of energy use through price mechanism: a developing country perspective

    1995-01-01

    As concern grows about the environmental aspect of energy use, it is increasingly suggested in recent years that energy pricing should take negative externalities of energy use into account. A large body of literature, both theoretical and applied, has grown up over the years proposing a variety of options and methods for internalising environmental costs. However, most of these theories and methods, developed in the industrialised countries, have hitherto neglected two aspects of developing economies: the existence of informal sector in the economy and widespread use of traditional energies. This paper discusses the issues related to internalising environmental costs through price mechanism when these two aspects are included. It also calls for a more careful analysis of energy and environmental policies. (author)

    Approximately 1.4 million migrant workers reside in Singapore, presenting unique infectious disease challenges to both migrants and Singapore. A Pubmed, MEDLINE (Ovid), EBSCO Host (Global Health) and Google Scholar search was performed for both peer, non-peer reviewed articles and reports relevant to migrant health in Singapore, published between 1 January 1989 and 1 September 2016. Additional studies were identified from citations within searched articles. We also reviewed published data and policy documents from the Ministries of Health and Manpower, Singapore. A significant proportion of malaria, enteric fevers, hepatitis A and E and tuberculosis diagnosed in Singapore involve migrant workers. From the 1990-2000 through 2009-11, while malaria and hepatitis A cases have decreased and remain sporadic, enteric fevers and tuberculosis cases have increased, possibly due to greater influx of migrant workers. Hepatitis E numbers remain low but migrant workers account for half of diagnosed cases. In an interplay of immune naivete, work and living conditions, migrants in the construction industry are at higher risk of arboviral infections such as dengue, Zika and chikungunya. Infections such as chikungunya were likely introduced into Singapore by travellers including migrant workers from the Indian subcontinent but autochthonous transmission continued due to the presence of competent mosquito vectors. There is less data regarding sexual health, networks and infections amongst migrant workers, an area which merits further attention. Migrant workers appear to be at higher risk than Singaporeans for specific infectious diseases, probably due to a complex interplay of several factors, including higher disease prevalence in their countries of origin, socio-economic factors, their living conditions in Singapore and financial, language and cultural barriers to healthcare access. Receiving countries need improved surveillance, expansion of preventive measures and decreased

    The aim of this study was to evaluate the feasibility, results, and cost-effectiveness of totally transanal endorectal pull-through (TEPT) in the management of rectosigmoid and midsigmoid Hirschsprung's disease (HD) in a low-income country. Between March 2004 and December 2005, 19 children underwent totally TEPT procedure. The patients' ages ranged from 6 days to 13 years. The primary diagnosis in all 19 patients was HD confined to the rectosigmoid region in 15 and midsigmoid in 4. None had a preoperative colostomy. Follow-up period ranged from 4 to 20 months (mean, 8 months). Ages ranged from 0.25 to 65 months, with a mean of 16.24 months. Weights ranged from 3.4 to 13 kg, with a mean of 6.5 kg. Mean time from diagnosis to pull-through procedure was 26 days (range, 6-39 days). The mean length of rectosigmoid resection was 30 cm (range, 20-50 cm). The mean operative time was 95 minutes (range, 75-140 minutes). Mean intraoperative blood loss was 25 mL (range, 15-40 mL). There was one death unrelated to the procedure. One patient had enterocolitis 3 months postoperatively. Average frequency of defecation was 3 (range, 1-6) stools per day. TEPT was associated with a shorter operating time, less blood loss, early return to feeds, and an overall reduced cost. The safety and cost-effective benefits of transanal endorectal pull-through in the treatment of HD are of special interest for a developing country. Our data also suggest that functional outcome following TEPT is highly satisfactory and comparable with other established procedures.

    The introduction of disease-modifying therapies (DMTs) - with varying degrees of efficacy for reducing annual relapse rate and disability progression - has considerably transformed the therapeutic landscape of relapsing-remitting multiple sclerosis (RRMS). We aim to develop rational evidence-based treatment recommendations and algorithms for the management of clinically isolated syndrome (CIS) and RRMS that conform to the healthcare system in a fast-developing economic country such as Qatar. We conducted a systematic review using a comprehensive search of MEDLINE, PubMed, and Cochrane Database of Systematic Reviews (1 January 1990 through 30 September 2016). Additional searches of the American Academy of Neurology and European Committee for Treatment and Research in Multiple Sclerosis abstracts from 2012 through 2016 were performed, in addition to searches of the Food and Drug Administration and European Medicines Agency websites to obtain relevant safety information on these DMTs. For each of the DMTs, the mode of action, efficacy, safety and tolerability are briefly discussed. To facilitate the interpretation, the efficacy data of the pivotal phase III trials are expressed by their most clinically useful measure of therapeutic efficacy, the number needed to treat (NNT). In addition, an overview of head-to-head trials in RRMS is provided as well as a summary of the several different RRMS management strategies (lateral switching, escalation, induction, maintenance and combination therapy) and the potential role of each DMT. Finally, algorithms were developed for CIS, active and highly active or rapidly evolving RRMS and subsequent breakthrough disease or suboptimal treatment response while on DMTs. The benefit-to-risk profiles of the DMTs, taking into account patient preference, allowed the provision of rational and safe patient-tailored treatment algorithms. Recommendations and algorithms for the management of CIS and RRMS have been developed relevant to the

    The number of Israeli travelers is increasing, including the number of travelers to developing countries. This study aimed to characterize the profile of Israeli travelers to developing countries. Data regarding demographics, travel destinations, trip duration and the purpose of travel were collected on travelers attending the pre-travel clinic at the Sheba Medical Center during a period of 9 years. Between the dates 1/1/1999 and 31/12/2007, 42,771 travelers presented for consultation at the Sheba Medical Center pre-travel clinic. The average age was 30.8 +/- 13.4 years and 54% of the travelers were males. The female proportion increased from 42% in 1999 to 49% in 2006. There was a steady increase in the number of travelers attending our clinic, except in 2003 (coinciding with the SARS epidemic). Post-army backpackers (20-25 year-old age group) were only 43% of the travelers. Children (60 years) comprised 4.4% and 4.6% of the travelers, respectively. The favorite destinations were Asia (55%), followed by Latin America (27%) and Africa (13%). The distribution of travel destinations varied significantly during the study period. Of note is the sharp decline in travel to Africa following the terrorist attack in Mombassa, Kenya (November 2002). The median trip duration changed during the study period, from 30 to 45 days, between 1999-2004 and 2005-2007 respectively. The majority (87%) of voyagers traveled for pleasure, 6% went for business, and 7% were representatives of governmental organizations. This study found an increasing diversity in the traveler population (more women, more children and older travelers) and more diversity in travel destinations. Disease outbreaks and terrorist attacks had transient negative impacts on the number of travelers.

    The history of photosynthesis research can be found in original papers and books. However, a special history is available from the prefatory chapters and the personal perspectives of various researchers who published them in several journals over the last 40 years. We have compiled a list of such perspectives published since 1964. Selection is not easy, especially of authors who were not directly engaged in photosynthesis research; some are included for their special insights related to central issues in the study of photosynthesis. Our journal, Photosynthesis Research, contains other valuable historic data in the occasional tributes, obituaries and historical notes, that have been published. Lists of these items are included. This article ends by listing the Nobel prizes related to photosynthesis and the Kettering Awards for Excellence in Photosynthesis Research. Wherever possible, a web page address is provided. The web page addresses have been taken from the article 'Photosynthesis and the Web: 2001' by Larry Orr and Govindjee, available at http://www.life.uiuc.edu/govindjee/photoweb and at http://photoscience.la.asu.edu/photosyn/ photoweb/default.html.When I find a bit of leisureI trifle with my papers.This is one of the lesserfrailities.'- Horace, Satires I, IV.

    The disclosure to patients of unfavorable news related to cancer remains a controversial issue in the Middle East. This study investigated the perspective of the public in Saudi Arabia regarding the disclosure of unfavorable cancer-related news. A convenience sample of 103 adult noncancer patients attending a family medicine clinic were asked to respond to 9 closed-ended questions. These questions reflected possible adverse news from the time of diagnosis until the end of life. The primary endpoint was an affirmative response (AR) to =7 questions (AR=7) indicating a preference to be informed of the majority (=78%) of adverse situations. One hundred individuals completed the questionnaire. Of these, 56 (56%) were male, and 44 (44%) were female. The median age was 32 years (18-75 years). Different questions were answered affirmatively by 76-99% of the responders. An AR=7 was reported by 83% of the responders. There was no statistically significant correlation between an AR=7 and age, gender or employment status (Chi-squared P values: 0.731, 0.427, and 0.148, respectively). There was a trend towards an AR=7 among those with higher levels of education compared to those with a lower level of education (88% and 73%, respectively, P=0.055). The results of this study suggest that the majority of Saudi Arabians prefer to be informed of most of the adverse health-related news if diagnosed with cancer. These results should encourage physicians to keep cancer patients informed of their health-related events unless the patient indicates otherwise.

    Electricity disclosure is required by the EU Directive concerning the internal market in electricity. According to the directive electricity suppliers shall make available to final customers the contribution of each energy source to the overall fuel mix and at least reference to existing sources where information on CO 2 emissions and the radioactive waste resulting from the electricity produced can be found. The information shall be reliable. The systems for electricity disclosure implemented or planned to be implemented differs among the Nordic countries and some countries currently apply some kind of transitional solutions. The systems applied at present cannot be easily combined, but extensive changes would only be needed in the Finnish system. Regulations for the Swedish system are also needed. Multiple counting (counting of e.g. environmental attributes more than once) occurs in all Nordic systems and at Nordic level as well. The Finnish system does not make corrections of environmental attributes from the electricity mix; Sweden and Norway currently apply transitional preliminary systems where the risk of multiple counting is obvious and Denmark does not yet fully apply the rules set up in their implemented system. However, in Sweden, Norway and Denmark it is likely that reliable systems will be implemented and applied - presumed that regulations for the Swedish system will be implemented according to previous plans. Multiple counting at Nordic level is a result of partly national multiple counting and partly due to application of different tracking systems, rules for import and export of electricity and attributes as well as rules and basis for correction of the residual (a residual is not at all used in Finland). Ten business customers have been interviewed regarding their opinions, requirements and desires with respect to electricity disclosure, but a clear picture has not emerged from these interviews. Several customers pay extra for some kind of green

    2017-12-01

    Full Text Available Background: With reports of widespread failures in South Africa’s land reform programmes, the levels of policy uncertainty in the political rhetoric that influences land reform have been increasing. Since 1994 policy targets to transfer land to black farmers have not been met. Of the 2005 target to transfer about 25 million ha of commercial farmland to black farmers by 2014, less than 5 million ha. have been transferred for commercial use. Some studies report failure rates in resettlement projects of up to 90%. To account for the failures, revisions of policies and amendments to legislations have been proposed within a political environment that is becoming increasingly intolerant to slow progress in land transfers and to resettlement failures. Aim: Against this environment, this paper presents a typology for understanding and evaluating important elements of the land reform project in order to influence progress in the process. Setting: The study adopts a historical review of land reform processes in post-colonial Kenya and Zimbabwe in order to identify potential challenges and key lessons for South Africa. Methods: Hence, using institutional and historical analytical lenses in exploring different narratives, the paper reviews reported failures and successes in land reform policy cases from the selected countries. From an institutional framework, prevalent social institutions and key lessons from Kenya, Zimbabwe and South Africa, a typology for evaluating important elements of the land reform process in South Africa is developed and discussed. Additionally, a review of global data collected on average sizes of farms in different regions of the world is provided as evidence to support propositions of what would constitute efficient farmland size ranges for small to medium commercial farms in South Africa. Results and conclusion: A proposition is made on how to use the typology to guide policy and research interventions to reduce failures

    The muriqui (Brachyteles spp.), endemic to the Atlantic Forest of Brazil, is the largest primate in South America and is endangered, mainly due to habitat loss. Its distribution limits are still uncertain and need to be resolved in order to determine their true conservation status. Species distribution modeling (SDM) has been used to estimate potential species distributions, even when information is incomplete. Here, we developed an environmental suitability model for the two endangered species of muriqui (Brachyteles hypoxanthus and B. arachnoides) using Maxent software. Due to historical absence of muriquis, areas with predicted high habitat suitability yet historically never occupied, were excluded from the predicted historical distribution. Combining that information with the model, it is evident that rivers are potential dispersal barriers for the muriquis. Moreover, although the two species are environmentally separated in a large part of its distribution, there is a potential contact zone where the species apparently do not overlap. This separation might be due to either a physical (i.e., Serra da Mantiqueira mountains) or a biotic barrier (the species exclude one another). Therefore, in addition to environmental characteristics, physical and biotic barriers potentially shaped the limits of the muriqui historical range. Based on these considerations, we proposed the adjustment of their historical distributional limits. Currently only 7.6% of the predicted historical distribution of B. hypoxanthus and 12.9% of B. arachnoides remains forested and able to sustain viable muriqui populations. In addition to measurement of habitat loss we also identified areas for conservation concern where new muriqui populations might be found.

In a knowledge economy, education, research and development represent the “new currency” by which nations achieve and maintain economic competitiveness. These sectors offer important enabling effects that can contribute to sustainable development of the respective economies. Nevertheless, reaching these broader objectives requires first of all certain corresponding measures such as ensuring optimum labour conditions and stimulating levels of wage earnings, both contributing to the increase of the motivation degree for education, research and development staff and to the attractiveness degree of the respective professions. The purpose of this study is to assess the place of education and research in the wage hierarchy in EU Member States and their relationship with the wages achieved in other fields. The results of our analysis indicate the existence of significant gaps between wages in European countries.

    Objective: To assess the needs related to prenatal genetic counselling in a developing country. Methods: The prospective observational study was conducted at the Prenatal-Genetic Counselling Clinic of Aga Khan University Hospital, Karachi, from October 2007 to September 2010. In-depth interviews were conducted and the data was stored in the form of patient charts. Information was then extracted from the charts and entered into a structured questionnaire. Results: Of the 93 couples in the study, 49(53%) were in the self-referral group and 44(47%) were in the physician-referral group. Diagnosis was not given for previously affected children by the paediatrician or by obstetrician for recurrent miscarriages in 68(73%)cases. Besides, 20(22%) couples had voluntarily terminated a pregnancy without any tests because of the fear of having a diseased child. Eleven (12%) couples were looking for amniocentensis or chorionic villus sampling. Death in previous children was the main reason to seek genetic counselling and was seen in 57(61%) couples. Consanguinity was seen in 77(83%) couples. Conclusion: A clear deficiency of knowledge of genetics was seen among the non-genetic healthcare providers. Demand of antenatal genetic testing among the public was also seen, highlighting the need of diagnostic facility for genetic and metabolic disorders. However, this needs to be explored in the context of the existing healthcare infrastructure. (author)

  13. Healthy ageing and home: the perspectives of very old people in five European countries.

    This paper reports on in-depth research, using a grounded theory approach, to examine the ways in which very old people perceive healthy ageing in the context of living alone at home within urban settings in five European countries. This qualitative study was part of a cross-national project entitled ENABLE-AGE which examined the relationship between home and healthy ageing. Interviews explored the notion of healthy ageing, the meaning and importance of home, conceptualisations of independence and autonomy and links between healthy ageing and home. Data analysis identified five ways in which older people constructed healthy ageing: home and keeping active; managing lifestyles, health and illness; balancing social life; and balancing material and financial circumstances. Older people reflected on their everyday lives at home in terms of being engaged in purposeful, meaningful action and evaluated healthy ageing in relation to the symbolic and practical affordances of the home, contextualised within constructions of their national context. The research suggests that older people perceive healthy ageing as an active achievement, created through individual, personal effort and supported through social ties despite the health, financial and social decline associated with growing older. The physicality and spatiality of home provided the context for establishing and evaluating the notion of healthy ageing, whilst the experienced relationship between home, life history and identity created a meaningful space within which healthy ageing was negotiated.

  14. New perspectives on the pedagogy of programming in a developing country context

    2012-09-01

    Programming education is a widely researched and intensely discussed topic. The literature proposes a broad variety of pedagogical viewpoints, practical approaches, learning theories, motivational vehicles, and other elements of the learning situation. However, little effort has been put on understanding cultural and contextual differences in pedagogy of programming. Pedagogical literature shows that educational design should account for differences in the ways of learning and teaching between industrialized and developing countries. However, the nature and implications of those differences are hitherto unclear. Using group interviews and quantitative surveys, we identified several crucial elements for contextualizing programming education. Our results reveal that students are facing many similar challenges to students in the west: they often lack deep level learning skills and problem-solving skills, which are required for learning computer programming, and, secondly, that from the students' viewpoint the standard learning environment does not offer enough support for gaining the requisite development. With inadequate support students may resort to surface learning and may adopt extrinsic sources of motivation. Learning is also hindered by many contextually unique factors, such as unfamiliar pedagogical approaches, language problems, and cultural differences. Our analysis suggests that challenges can be minimized by increasing the number of practical exercises, by carefully selecting between guided and minimally guided environments, by rigorously monitoring student progress, and by providing students timely help, repetitive exercises, clear guidelines, and emotional support.

    2006-09-01

    Full Text Available Purpose: To propose a social-and-democrat health policy alternative to the current neoliberal one. Context of case: The general failure of neoliberal health policies in low and middle-income countries justifies the design of an alternative to bring disease control and health care back in step with ethical principles and desired outcomes. Data sources: National policies, international programmes and pilot experiments—including those led by the authors—are examined in both scientific and grey literature. Case description: We call for the promotion of a publicly-oriented health sector as a cornerstone of such alternative policy. We define ‘publicly-oriented’ as opposed to ‘private-for-profit’ in terms of objectives and commitment, not of ownership. We classify development strategies for such a sector according to an organisation-based typology of health systems defined by Mintzberg. As such, strategies are adapted to three types of health systems: machine bureaucracies, professional bureaucracies and divisionalized forms. We describe avenues for family and community health and for hospital care. We stress social control at the peripheral level to increase accountability and responsiveness. Community-based, national and international sources are required to provide viable financing. Conclusions and discussion: Our proposed social-and-democrat health policy calls for networking, lobbying and training as a joint effort in which committed health professionals can lead the way.

  16. Managing Unplanned Pregnancies in Five Countries: Perspectives on Contraception and Abortion Decisions

    Science.gov (United States)

    2014-01-01

    Why is induced abortion common in environments when modern contraception is readily available? This study analyzes qualitative data collected from focus group discussions and in-depth interviews with women and men from low income areas in five countries -- the U.S., Nigeria, Pakistan, Peru and Mexico -- to better understand how couples manage their pregnancy risk. Across all settings, women and men rarely weigh the advantages and disadvantages of contraception and abortion before beginning a sexual relationship or engaging in sexual intercourse. Contraception is viewed independently of abortion, and the two are linked only when the former is invoked as a preferred means to avoiding repeat abortion. Contraceptive methods are viewed as suspect because of perceived side effects, while abortion experience, often at significant personal risk, raised the specter of social stigma and motivation for better contraceptive practice. In all settings, male partners figure importantly in pregnancy decisions and management. Although there are inherent limitations from small sample sizes, the study narratives reveal psychosocial barriers to effective contraceptive use and identify nodal points in pregnancy decision-making that can inform and structure future investigation.

    To determine the outcomes of surgical management of inflammatory bowel disease. The retrospective case series was conducted at Aga Khan University Hospital, Karachi, and comprised medical record of adult patients operated between January 1986 and December 2010 for inflammatory bowel disease. Outcomes consisted of complications till last follow-up and 30-day mortality (disease or procedure related). Functional status of patients with ileal pouch was determined via telephone. SPSS 16 was used to analyse data. Of the 36 patients whose records were reviewed, 21(58%) were males, and body mass index was less than 23 in 34(91%). A total of 27(75%) patients underwent elective surgery for their condition. Ileal pouch was formed in 9(25%). Overall mortality was 14(38.8%). Overall incidence of complications was 26(72%), with wound infection being the most common early morbidity in 11(30.5%). Late morbidity included pouchitisin 4/9 (44.9%) and strictures 2/36 (5.5%).On telephonic follow-up, 6 of the remaining 7patients (85%) with ileal pouch were satisfied with the functional results of the procedure. The retrospective case series represents results from a developing country with low prevalence of inflammatory bowel disease and hence limited experience.

    To assess the long-term outcome of lupus nephritis in children with systemic lupus erythematosus followed up over 12 years at a tertiary care teaching hospital in Eastern India. This is a retrospective observational study of the clinicopathological presentation, management, and outcome in 46 children with lupus nephritis over a period of 12 years at a tertiary teaching hospital in Eastern India. Mortality was compared between different lupus classes and therapy groups with Kaplan-Meier analysis and log-rank test. The incidence of lupus nephritis was 58.97% [95% confidence interval (CI) 48.06%-59.89%] with the mean age at presentation being 10.2±2.43 years (range 5.5-14.5) years. Majority belonged to class IV (30.43%), followed by class II (26.91%), class III (23.91), and class V (8.70%). Outcome analysis of children with lupus nephritis over 12 years revealed that 24 (52.17%) achieved complete remission of disease activity, 5 attained partial remission, 4 continued to have active disease, 5 developed end-stage renal disease (ESRD), and 8 died. Overall mortality thus observed was 17.39% with septicemia in the background of ESRD being the commonest cause. No significant difference in mortality was observed between different lupus nephritis classes or therapy arm groups. The study throws light on various aspects of lupus nephritis and their long-term outcome patterns in children from developing countries such as India.

    There is a need for speech-language pathology (SLP) research in the Philippines, in order to fill in knowledge gaps relevant to the local context. Information about the local SLP research status remains inadequate. This study describes local SLP research done over the almost past four decades. Using a descriptive retrospective design, a search was made for all empirical research articles completed by Filipino SLPs from 1978 to 2015. A total of 250 research articles were identified and described along several parameters. A predominant number were authored by the SLPs in the academe (97.20%). There was a focus on language (27.60%) and the nature of communication/swallowing disorders (20.80%). More than half utilised quantitative exploratory research designs (69.20%). Several used survey forms to generate data (38.41%). Nearly all were unpublished (93.60%) and were unfunded (94.80%). The current study revealed a dearth of research studies, limited diversity of research articles, limited research dissemination and funding concerns. It is suggested that the results of the current study can serve as a reference point to restructure research systems in the Philippines and in other developing countries, and offer data that can be used to develop a research agenda for the profession.

    Full Text Available Cristiana Berti,1 Mieke Faber,2 Cornelius M Smuts11Centre for Excellence in Nutrition, North-West University, Potchefstroom, South Africa; 2Non-communicable Diseases Research Unit, South African Medical Research Council, Tygerberg, South AfricaAbstract: Despite strategies employed to tackle micronutrient malnutrition, limited progress has been achieved in the developing countries. Of global concern are deficiencies in iron, vitamin A, zinc, folate, and iodine. This review aims to explore up-to-date scientific evidence on the effect of different micronutrient strategies on biomarkers and health outcomes, and for each strategy, to highlight strengths, limitations, and factors contributing to success or failure. PubMed/MEDLINE and EBSCO databases and Google-indexed scientific literature were searched for relevant articles and documents, limited to human studies reported since 2003. Evidence shows that the most cost-effective approaches to address symptoms of micronutrient malnutrition are targeted supplementation and/or fortification with iron, iodine, zinc, folic acid, vitamin A, and multimicronutrients, provided that households have access to primary health care and that there is consistent long-term coverage, monitoring, adequate marketing, and commercial commitment. Dietary diversification/modification interventions are probably the most sustainable strategies to address causes of deficiency, but permanent solutions are still required in controlling micronutrient malnutrition at both research and public health levels. Furthermore, many scientific gaps remain, hindering the development of robust public health guidance. These gaps are due to the paucity of well-designed community-based studies, lack of information on biological mechanisms behind relationships between micronutrients and outcomes, and inconsistent results. Further adequately powered long-term trials are needed to fill these gaps. Lessons learned from large-scale nutritional

    Full Text Available Abstract Background Living in a world greatly controlled by mass media makes it impossible to escape its pervading influence. As media in Pakistan has been free in the true sense of the word for only a few years, its impact on individuals is yet to be assessed. Our study aims to be the first to look at the effect media has on the body image of university students in a conservative, developing country like Pakistan. Also, we introduced the novel concept of body image dissatisfaction as being both negative and positive. Methods A cross-sectional study was conducted among 7 private universities over a period of two weeks in the city of Karachi, Pakistan's largest and most populous city. Convenience sampling was used to select both male and female undergraduate students aged between 18 and 25 and a sample size of 783 was calculated. Results Of the 784 final respondents, 376 (48% were males and 408 (52% females. The mean age of males was 20.77 (+/- 1.85 years and females was 20.38 (+/- 1.63 years. Out of these, 358 (45.6% respondents had a positive BID (body image dissatisfaction score while 426 (54.4% had a negative BID score. Of the respondents who had positive BID scores, 93 (24.7% were male and 265 (65.0% were female. Of the respondents with a negative BID score, 283 (75.3% were male and 143 (35.0% were female. The results for BID vs. media exposure were similar in both high and low peer pressure groups. Low media exposure meant positive BID scores and vice versa in both groups (p Conclusions Our study confirmed the tendency of the media to have an overall negative effect on individuals' body image. A striking feature of our study, however, was the finding that negative body image dissatisfaction was found to be more prevalent in males as compared to females. Likewise, positive BID scores were more prevalent amongst females.

    There is no clear evidence as to whether the co-location of primary care professionals in the same facility positively influences their way of working and the quality of healthcare as perceived by patients. The aim of this study was to identify the relationships between general practitioner (GP) co-location with other GPs and/or other professionals and the GP outcomes and patients' experiences. We wanted to test whether GP co-location is related to a broader range of services provided, the use of clinical governance tools and inter-professional collaboration, and whether the patients of co-located GPs perceive a better quality of care in terms of accessibility, comprehensiveness and continuity of care with their GPs. The source of data was the QUALICOPC study (Quality and Costs of Primary Care in Europe), which involved surveys of GPs and their patients in 34 countries, mostly in Europe. In order to study the relationships between GP co-location and both GPs' outcomes and patients' experience, multilevel linear regression analysis was carried out. The GP questionnaire was filled in by 7183 GPs and the patient experience questionnaire by 61,931 patients. Being co-located with at least one other professional is the most common situation of the GPs involved in the study. Compared with single-handed GP practices, GP co-location are positively associated with the GP outcomes. Considering the patients' perspective, comprehensiveness of care has the strongest negative relationship of GP co-location of all the dimensions of patient experiences analysed. The paper highlights that GP mono- and multi-disciplinary co-location is related to positive outcomes at a GP level, such as a broader provision of technical procedures, increased collaboration among different providers and wider coordination with secondary care. However, GP co-location, particularly in a multidisciplinary setting, is related to less positive patient experiences, especially in countries with health systems

    Human exploitation of sea turtles in Venezuela dates back at least 800 years and continues to the present day. The first concerns about the status of sea turtle populations arose in the 1970s, and the projects from this early era were a tagging program, beach evaluation and in situ nest protection. Since then, efforts to develop a sea turtle research and conservation sector in Venezuela have resulted in a number of successes and rather more failures. Among the achievements is a course 'Sea Turtle Biology and Conservation Techniques', which has now been run for 15 years and has educated several hundred participants and enabled the establishment of a valuable professional network, and the publication of the Venezuelan 'Sea Turtle Recovery Action Plan' in 2000. But Venezuela shares with other developing countries some crucial shortcomings which have restricted the success of conservation and research efforts. Whilst regulations relating to protected areas and natural resource use have proliferated, enforcement is weak. Community-based projects and environmental education programs exist, but levels of participation are low. A large number of conservation approaches have been applied, including head-starting and nest translocation to hatcheries, but their value as conservation tools remains unproven. Research has increased, but its impact on decision-making is not significant. Taking an insider's perspective on the challenges to date in sea turtle research and conservation in Venezuela reveals much about the reality facing conservation scientists in developing countries and the forces that shape and can potentially derail research and conservation efforts.

    Men entering the nursing profession have been investigated from several different perspectives. Due to male gender characteristics and existing public image, nursing is often not considered as a career choice by men. Whether nursing would benefit from increased number of men is a key question in the literature. The purpose of this integrative review of the literature was to identify factors influencing men to enter the nursing profession. In addition, it sought to understand the challenges they are confronted within this profession. A systematic search of the existing literature was performed using an Internet search with broad keywords to access related articles in both Persian and English databases. Finally, 34 studies (written between 2000 and early 2013) were selected and surveyed. Most of the studies were conducted in developed counties. The review identified reasons why males choose nursing, and other challenges facing men entering and working in nursing. Themes that emerged from the literature include educational and societal barriers experienced by men in nursing, recruitment, career choice, and role strain. Regarding men's influences on professional development, and also the importance of gender-based caring, policies for recruitment and retention of men in nursing must be followed hastily. However, there is a need for further research regarding the challenges faced by men entering nursing, in both Iran and other developing countries.

    On February 6, 1992, approximately 35 SRS personnel from DOE, WSRC, and Dames and Moore attended a very informative talk given by Dr. E.L. Albenesius who discussed the operation of the SRS Burial Ground from an historical perspective. Dr. Albenesius, a Du Point retiree, formerly served as research manager of SRL's Environmental Effects and Solid Waste Management Technology Divisions among other assignments. One notable point Dr. Albenesius made was in answer to a question concerning what was the most important thing that could be done to reduce the hazard to man from buried waste. His response was to remove as much plutonium as practical prior to closure. In order to preserve this valuable information for the record, the program was audiotaped from which a point-by-point chronological transcription, with minor editing, was prepared

    Personality factors such as time perspective and sensation-seeking have been shown to predict smoking uptake. However, little is known about the influences of these variables on quitting behavior, and no prior studies have examined the association cross-nationally in a large probability sample. In the current study it was hypothesized that future time perspective would enhance - while sensation-seeking would inhibit - quitting activity among smokers. It was anticipated that the effects would be similar across English speaking countries. Using a prospective cohort design, this cross-national study of adult smokers (N=8845) examined the associations among time perspective, sensation-seeking and quitting activity using the first three waves of data gathered from the International Tobacco Control Four Country Survey (ITC-4), a random digit dialed telephone survey of adult smokers from the United Kingdom, United States, Canada and Australia. Findings revealed that future time perspective (but not sensation-seeking) was a significant predictor of quitting attempts over the 8-month follow-up after adjusting for socio-demographic variables, factors known to inhibit quitting (e.g., perceived addiction, enjoyment of smoking, and perceived value of smoking), and factors known to enhance quitting (e.g., quit intention strength, perceived benefit of quitting, concerns about health effects of smoking). The latter, particularly intention, were significant mediators of the effect of time perspective on quitting activity. The effects of time perspective on quitting activity were similar across all four English speaking countries sampled. If these associations are causal in nature, it may be the case that interventions and health communications that enhance future-orientation may foster more quit attempts among current smokers.

    Concepts of autism have evolved over the twentieth century after Bleuler coined the term to refer to symptoms of self-absorption in those with schizophrenia. Autism nosology changed to the current sesquipedalian constellation of autism spectrum disorders with a confusing archipelago of 5 conditions that often serve as islands of confusion to both the general public and professionals. This article reviews historical links that have led to the current confusing and controversial situation that is encouraging some people to return to magic, mysticism, and mantics for health care, despite the amazing accumulation of progress in vaccinology over the past 2 centuries.

    In this paper I will look at aspects of cultural difference as well as commercial and political relationships between East and West in a literary and historical context. These aspects have become evident during research for my PhD by practice, which involves creating a contemporary, gay, screen adaptation of the story of Madame Butterfly. I will demonstrate how the story, by American author John Luther Long, emerged in response to the fashion of ‘Japonisme’, which was prompted by the opening ...

    Ashby, Nathan; Squiers, Joshua

    2014-09-01

    The historical development of the concept of perfusion is traced, with particular focus on the development of the modern clinical concepts of perfusion through the fields of anatomy, physiology, and biochemistry. This article reviews many of the significant contributors to the changing ideas of perfusion up through the twentieth century that have influenced the modern physiologic circulatory and metabolic models. The developments outlined have provided the modern model of perfusion, linking the cardiopulmonary circulation, tissue oxygen utilization and carbon dioxide production, food intake, tissue waste production and elimination, and ultimately the production and utilization of ATP in the body.

    Full Text Available Purpose – The purpose of this paper is to establish the level of importance of the country of origin (COO in the purchasing process of different categories of consumer goods in the research context of Bosnia and Herzegovina (B&H. Design/Methodology/Approach – The study is based on primary data collected through a survey questionnaire on a consumer sample in B&H. The analysis consists of several levels: establishing a level of COO importance for consumers; establishing a level of consumer familiarity with a COO; identifying the influence of consumer ethnocentrism on the level of COO importance. Findings and implications – ANOVA and T-paired tests highlighted the importance of COO to vary across product categories. The results of regression analysis showed that consumer ethnocentrism significantly influences the level of COO importance in the purchasing process. The results contribute to the thesis that COO has a diagnostic value for the consumers in the purchasing process and can therefore be used as a marketing tool in providing better market acceptance and positioning of products. Limitations – This research has a limited scope considering that it is a single-market study, but also because of the small range of researched product categories. Further research studies should consider a wider range of product categories, as well as a cross-cultural research approach to explore the importance of COO on the overall purchasing process. Originality – This study represents an integrative approach to the phenomenon of COO, consisting of consumer ethnocentrism, product characteristics, and consumer perspective regarding COO importance and familiarity.

  19. Accounting and auditing of sectional title property: An overview from the governance perspective in a developing country

    2017-02-01

    Full Text Available The sectional title industry has been a part of the property landscape in South Africa for almost half a century, and plays a profound role in addressing the housing problem in the country. Stakeholders such as owners and investors in sectional title property are in most cases not directly involved in the management thereof, and place reliance on the audited annual financial statements of bodies corporate for decision-making purposes. Although the industry seems to be highly regulated, the legislation regarding accounting and auditing of sectional title property is vague and ambiguous. Furthermore, there are no industry-specific auditing and accounting standards to guide accounting and auditing practitioners in performing their work and industry financial benchmarks are not readily available. In addition, financial pressure on sectional title schemes is often very high due to the fact that some owners exercise unrealistic pressure to keep monthly levies as low as possible. Very little academic research has been undertaken on the sectional title industry in South Africa from an accounting and auditing perspective. The aim of this article is threefold: Firstly, to discuss the findings of a literature review on uncertainties, ambiguity and confusing aspects in legislation regarding the audit of sectional title property that may cause or increase the audit expectation gap. Secondly, to discuss the empirical findings of accountancy-related aspects of a sample of body corporate financial statements and accompanying audit reports, in order to identify current benchmarks, challenges, trends, deficiencies in reporting and possible norms for the sectional title industry. Specific reference will be made to the difference between the bodies corporate in the Mangaung and Matjhabeng areas. Thirdly, practical recommendations will be made on possibilities of closing the expectation gap, and further research opportunities in this regard will be discussed.

    While many studies have addressed the Korean nurse immigration to Germany in 1960s-70s in terms of the nurses' personal histories from a national perspective, few studies have pointed to its transnational impact on the medical field. Given this gap, the paper discusses its significance in the medical history through examining the nursing culture and policy changes made in both countries initiated by the immigration of the qualified Korean nurses. For this end, the paper first discusses differences between Korea and Germany in the nursing culture and professional standards at the time of the nurse immigration. The study then examines the transnational changes in the two nations in the nursing professional culture and related policies including nurse education and qualification process. More specifically, the paper argues that the Korean female nurses not only supplied labor in need but also contributed to the medical policy changes in Germany. The prevalent stereotype of nursing as a non-professional field in the German society begin to change while experiencing professionally qualified Asian immigrant nurses and practiced treatments that had been conduced by German doctors by then. This observation actually leads to the policy level reforms in nursing education and qualification process to meet the need of high-quality nurses when the labor immigration was stopped in mid-1970s. The paper also points out that the influence of the nurse immigration on the Korean society is not merely economic; it brought the policy level reforms in nurse education and qualification as well. The immigration, resulting in a lack of nurses in the Korean society, triggered two main responses: the expansion of the existing nurse education system and the establishment of a new system called "nursing assistant."

  1. Historical perspectives on channel pattern in the Clark Fork River, Montana and implications for post-dam removal restoration

    Active restoration approaches such as channel reconstruction have moved beyond the realm of small streams and are being applied to larger rivers. Uncertainties arising from limited knowledge, fluvial and ecosystem variability, and contaminants are especially significant in restoration of large rivers, where project costs and the social, infrastructural, and ecological costs of failure are high. We use the case of Milltown Dam removal on the Clark Fork River, Montana and subsequent channel reconstruction in the former reservoir to examine the use of historical research and uncertainty analysis in river restoration. At a cost of approximately $120 million, the Milltown Dam removal involves the mechanical removal of approximately 2 million cubic meters of sediments contaminated by upstream mining, followed by restoration of the former reservoir reach in which a single-thread meandering channel is being constructed. Historical maps, surveys, photographs, and accounts suggest a conceptual model of a multi-thread, anastomosing river in the reach targeted for channel reconstruction, upstream of the confluence of the Clark Fork and Blackfoot Rivers. We supplemented historical research with analysis of aerial photographs, topographic data, and USGS stage-discharge measurements in a lotic but reservoir-influenced reach of the Clark Fork River within our study area to estimate avulsion frequency (0.8 avulsions/year over a 70-year period) and average rates of lateral migration and aggradation. These were used to calculate the mobility number, a dimensionless relationship between channel filling and lateral migration timescales that can be used to predict whether a river’s planform is single or multi-threaded. The mobility number within our study reach ranged from 0.6 (multi-thread channel) to 1.7 (transitional channel). We predict that, in the absence of active channel reconstruction, the post-dam channel pattern would evolve to one that alternates between single and multi

  2. Historical and Physical Account on Entropy and Perspectives on the Second Law of Thermodynamics for Astrophysical and Cosmological Systems

    Full Text Available We performed an in depth analysis of the subjects of entropy and the second law of thermodynamics and how they are treated in astrophysical systems. These subjects are retraced historically from the early works on thermodynamics to the modern statistical mechanical approach and analyzed in view of specific practices within the field of astrophysics. As often happens in discussions regarding cosmology, the implications of this analysis range from physics to philosophy of science. We argue that the difficult question regarding entropy and the second law in the scope of cosmology is a consequence of the dominating paradigm. We further demonstrate this point by assuming an alternative paradigm, not related to thermodynamics of horizons, and successfully describing entropic behavior of astrophysical systems.

    Being a woman in engineering, and in particular, being the woman with the dubious distinction of having the most years at Dryden, gives the author a long-term perspective on the women who worked in the engineering field and their working environment. The working environment for the women was influenced by two main factors. One factor was the Dryden's growth of 14 persons (2 of them women) at the end of 1946 to the present size. The other factor was the need for programming knowledge when the digital computers came into use. Women have been involved with flight research at Dryden since the days of the first transonic and supersonic airplanes. This paper uses available records, along with memory, to document the number of women in engineering at Dryden, to comment about observed trends, and to make personal observations.

    2004-06-01

    Full Text Available This report will trace the development of the historical earthquake catalog of the Philippines, assess its present state and recommend future research directions. The current Philippine historical earthquake catalog is culled from various catalogs, both global and local, that were developed since the first Philippine catalog by Perrey was published in 1860. While early global catalogs gave simple mention of earthquakes in the Philippines, more focused earthquake catalogs about the Philippines gave more explicit descriptions of earthquake accounts and adopted descriptions by local historians. Over the years, various historians and seismologists continued to compile their catalogs whose contents depended on the author?s perspectives and purposes. These works varied from simple listings to others including detailed descriptions. It was only recently that an attempt made to parameterize the magnitudes and epicenters of Philippine historical earthquakes using magnitude-felt area relations was done. A more detailed catalog, however, is now underway that will show details of intensity distribution for each significant historical earthquake. By comparing the historical catalog with the recent catalog and assuming that the recent catalog is complete, we find that there are still a substantial amount of historical earthquakes that needs to be reviewed and located. Possible sources of new information are local libraries, museums and archives in the Philippines, Spain and other Southeast Asian countries to which the country was in contact with during historical times.

  6. Rise, fall and resurrection of chromosome territories: a historical perspective. Part I. The rise of chromosome territories

    2009-06-01

    Full Text Available It is now generally accepted that chromosomes in the cell nucleus are organized in distinct domains, first called chromosome territories in 1909 by the great cytologist Theodor Boveri. Yet, even today chromosomes have remained enigmatic individuals, whose structures, arrangements and functions in cycling and post-mitotic cells still need to be explored in full detail. Whereas numerous recent reviews describe present evidence for a dynamic architecture of chromosome territories and discuss the potential significance within the functional compartmentalization of the nucleus, a comprehensive historical account of this important concept of nuclear organization was lacking so far. Here, we describe the early rise of chromosome territories within the context of the discovery of chromosomes and their fundamental role in heredity, covering a period from the 1870th to the early 20th century (part I, this volume. In part II (next volume we review the abandonment of the chromosome territory concept during the 1950th to 1980th and the compelling evidence, which led to its resurrection during the 1970th to 1980th.

    Directory of Open Access Journals (Sweden)

    Shichen Wang

    2015-12-01

    Full Text Available People-to-people exchange has become a heated topic of the Chinese foreign policy. Since the beginning of the twenty-first century, China has established people-to-people dialogues with the United States, the European Union, the United Kingdom, France and Russia. In 2012, China and the EU established a high-level dialogue for people-to-people exchange, making people-to-people exchange the third pillar of China-EU relations. However, China is not a newcomer to people-to-people exchanges with Europe. Why does China launch the people-to-people diplomacy? Is it a plus or a must for China as well as for China-EU relations? The author reviews the history and current situation of China's people-to-people exchange and investigates China’s motivations behind the policy. Using the historical institutionalism as an approach, this paper argues that people-to-people diplomacy is a key component of the contemporary Chinese foreign policy towards Europe. China has long been an unequal counterpart to Europe since the 1840s. After the development of bilateral political and economic cooperation in the past four decades, people-to-people diplomacy is the last part that China needs to finish in order to regain equal status with Europe. In addition, it is also a step towards realising the "great rejuvenation of the Chinese nation".

  8. A cultural historical activity theory perspective to understand preservice science teachers' reflections on and tensions during a microteaching experience

    This study draws from cultural historical activity theory (CHAT) to analyze preservice teachers' reflections on a microteaching activity. Microteaching activities involved preservice educators teaching middle school students from local schools. The study was conducted with 23 preservice teachers enrolled in a large university's teacher education program. During this secondary science teaching methods course, every pair of preservice teachers engaged in 20 minute microteaching activity with 3-5 middle school students. The microteaching was videotaped, and the teachers subsequently provided voice-over reflections on a second audio track. Transcriptions of the microteaching events were analyzed through the formation of event maps showing the phases of activity and the organizational sequence of actions. Event maps were used to investigate the focus of preservice teachers' reflections. The results showed that while learning from their microteaching, preservice teachers focused primarily on the mediating artifacts and gave least attention to the larger teaching community surrounding these activities. Use of CHAT helped to identify challenges in different elements of the microteaching activity. The study contributes to how reflective practice can be enhanced through attention to the social and cultural dimensions of the teaching.

    1992-05-01

    Full Text Available This volume contains historical studies of several sciences as practiced at Harvard University. Two of these studies have relevance to the history of archaeology. A chapter by Toby Appel focuses upon the scientific career of Jeffries Wyman, first curator of Harvard's Peabody Museum. She contrasts Wyman's unassuming character with the dominating personality of his mentor and contemporary Louis Agassiz. Trained as a medical doctor, Wyman's main love was zoology, particularly comparative anatomy. In his mid-40s, he encountered his first shell midden and was bitten by the archaeology bug. Soon he was doing pioneering excavation in both New England and Florida. In 1866, he was selected to be the curator of the Peabody Museum, primarily upon his strong museum background but also because of the high regard with which he was held by certain influential people. His selection to this position may have made him America's first professional archaeologist. His principal responsibilities were to collect and display archaeological and ethnological specimens and he made great steps in this direction prior to his death in 1874. Wyman's scientific work was poorly known or studied (he is best noted for having made the first scientific description of the gorilla, in part, Appel argues, because he did not seek acclaim or controversy. His greatest influence was locally through personal interactions with students and colleagues. His archaeological work is only briefly discussed in this and the following article, and there is still much to be written about this man of high character.

    Full Text Available Ex-post evaluations of energy policies in Malaysia between 1970 and 2010 were conducted. The developments of energy policies in Malaysia were traced from the early 1970s with the introduction of the country’s first energy-related policy all the way to 2010 with the country’s first endeavour towards a biobased energy system. Analyses revealed that many of the policies were either: (1 directly responding to changes in global/domestic socioeconomic and political events, or (2 provided visions to guide developments of the energy sector in alignment with the country’s growth agenda. Critical examinations of the country’s actual energy consumptions during these 40 years were also conducted to evaluate the efficacy of these energy-related policies. Three noteworthy successes in Malaysia’s energy landscape are: (1 the formation of PETRONAS as the national oil and gas company; (2 reduction of country’s over-reliance on oil as a single source of energy by significantly growing the production and use of natural gas in a short span of time; and (3 creation of a thriving oil and gas value chain and ecosystem in the country. However, the country is still critically dependent on scarce petroleum resources, despite having an abundance of renewable reserves. Progress towards renewable energy has been too little and too slow.

    2003-03-01

    Emotional stress acutely and repetitively causing blood pressure increase or aggravating existing hypertension is usually not reflected by norepinephrine and epinephrine increase but by a sudden rise of dopamine, the third "defensive" catecholamine coping with the damaging neuropsychological and cardiovascular actions of the first two. This double-edged sympathetic response to emotional stress evolves during human lifespan and long-term evolution of hypertension. In the course of philogenesis it carries a potential mismatch between the normal physiology of the human dopaminergic system and current environmental (emotional particularly) conditions in industrialized countries. This offers a rational support to a mental stress-cardiovascular diseases relationship proposed 40 years ago in a WHO report which followed a memorable 1960 Prague Hypertension Meeting.

    2012-01-01

    Radioactive iodine (RAI, 131 I) has been used as a therapeutic agent for differentiated thyroid cancer (DTC) with over 50 years of history. Recently, it is now attracting attention in medical fields as one of the molecular targeting therapies, which is known as targeted radionuclide therapy. Radioactive iodine therapy (RIT) for DTC, however, is now at stake in Japan, because Japan is confronting several problems, including the recent occurrence of the Great East Japan Disaster (GEJD) in March 2011. RIT for DTC is strictly limited in Japan and requires hospitalization. Because of strict regulations, severe lack of medical facilities for RIT has become one of the most important medical problems, which results in prolonged waiting time for Japanese patients with DTC, including those with distant metastasis, who wish to receive RIT immediately. This situation is also due to various other factors, such as prolonged economic recession, super-aging society, and subsequent rapidly changing medical environment. In addition, due to the experience of atomic bombings in Hiroshima and Nagasaki, Japanese people have strong feeling of ''radiophobia ''. There is fear that GEJD and related radiation contamination may worsen this feeling, which might be reflected in more severe regulation of RIT. To overcome these difficulties, it is essential to collect and disclose all information about the circumstances around this therapy in Japan. In this review, we would like to look at this therapy through several lenses, including historical, cultural, medical, and socio-economic points of view. We believe that clarifying the problems is sure to lead to the resolution of this complicated situation. We have also included several recommendations for future improvements. (author)

    During the latter part of the 20th century, work stress became an important societal issue and a huge amount of scientific attention went to studying it. This paper examines the process of formulating and defining the concept of work stress in the occupational health sciences and in industrial and organizational psychology from the early 1960s to the late 1990s. The empirical material of the study encompasses 108 scientific articles, books, book chapters, 'state of the art' reviews, book reviews, and written conference presentations. The data are analysed in the frameworks of historical sociology, critical psychology, and the anthropology of knowledge. We argue that work stress as a life-structuring concept gained ground in psychosocial and occupational health sciences (and also in lay understanding) in the 1960s simultaneously with the rise of social reformist movements that called for fundamental changes emphasizing democratic and human-orientated work organizations and socially responsible values. With the passing of time, however, the focus on structural improvement of work life waned and the emphasis shifted towards the apolitical occupational health aspects of work stress. Researchers with a psychological orientation emphasized micro-level characteristics as factors affecting work stress, whereas stress-orientated epidemiologists turned to the study of specific occupational stress models and/or risk factors. The emergence and development of work stress research can be seen as a chain of attempts to define and identify new risks and experiences occurring in work life. The process, driven by a gradual shift from industrial environments towards organizational frameworks characterized by social and psychological dimensions, reflected the overall shift towards modern democratic work life and the information society in which employees' emotions and well-being became an issue.

  17. Historizing epistemology in psychology.

    Jovanović, Gordana

    2010-12-01

    The conflict between the psychometric methodological framework and the particularities of human experiences reported in psychotherapeutic context led Michael Schwarz to raise the question whether psychology is based on a methodological error. I take this conflict as a heuristic tool for the reconstruction of the early history of psychology, which bears witness to similar epistemological conflicts, though the dominant historiography of psychology has largely forgotten alternative conceptions and their valuable insights into complexities of psychic phenomena. In order to work against the historical amnesia in psychology I suggest to look at cultural-historical contexts which decisively shaped epistemological choices in psychology. Instead of keeping epistemology and history of psychology separate, which nurtures individualism and naturalism in psychology, I argue for historizing epistemology and for historical psychology. From such a historically reflected perspective psychology in contemporary world can be approached more critically.

  18. Toward an epistemology of nano-technosciences: Probing technoscience from a historical perspective: on today's surprising prevalence and relevance of Francis Bacon.

    Schmidt, Jan C

    2011-12-01

    This paper aims to contribute to the attempts to clarify and classify the vague notion of "technosciences" from a historical perspective. A key question that is raised is as follows: Does Francis Bacon, one of the founding fathers of the modern age, provide a hitherto largely undiscovered programmatic position, which might facilitate a more profound understanding of technosciences? The paper argues that nearly everything we need today for an ontologically well-informed epistemology of technoscience can be found in the works of Bacon-this position will be called epistemological real-constructivism. Rather than realist or constructivist, empiricist or rationalist, Bacon's position can best be understood as real-constructivist since it challenges modern dichotomies. Reflection upon the contemporary relevance of Bacon could contribute to the expanding and critical discussion on technoscience. In the following I will reconstruct the term "technoscience". My finding is that at least four different understandings or types of the term "technoscience" co-exist. In a second step, I will analyze and elaborate on Bacon's epistemological position. I will identify central elements of the four different understandings in Bacon's work. Finally, I will conclude that the epistemology of technoscience is, indeed, very old-it is the epistemological position put forward by Bacon.

    Since 1945, the reason for humanitarian crises and the way in which the world responds to them has dramatically changed every 10 to 15 years or less. Planning, response, and recovery for these tragic events have often been ad hoc, inconsistent, and insufficient, largely because of the complexity of global humanitarian demands and their corresponding response system capabilities. This historical perspective chronicles the transformation of war and armed conflicts from the Cold War to today, emphasizing the impact these events have had on humanitarian professionals and their struggle to adapt to increasing humanitarian, operational, and political challenges. An unprecedented independent United Nations-World Health Organization decision in the Battle for Mosul in Iraq to deploy to combat zones emergency medical teams unprepared in the skills of decades-tested war and armed conflict preparation and response afforded to health care providers and dictated by International Humanitarian Law and Geneva Convention protections has abruptly challenged future decision-making and deployments.

  20. The Long-term Impact of Early Life Pain On Adult Responses to Anxiety and Stress: Historical Perspectives and Empirical Evidence

    Victoria, Nicole C.; Murphy, Anne Z.

    2016-01-01

    Approximately 1 in 6 infants are born prematurely each year. Typically, these infants spend 25 days in the Neonatal Intensive Care Unit (NICU) where they experience 10–18 painful and inflammatory procedures each day. Remarkably, pre-emptive analgesics and/or anesthesia are administered less than 25% of the time. Unalleviated pain during the perinatal period is associated with permanent decreases in pain sensitivity, blunted cortisol responses and high rates of neuropsychiatric disorders. To date, the mechanism(s) by which these long-term changes in stress and pain behavior occur, and whether such alterations can be prevented by appropriate analgesia at the time of insult, remains unclear. Work in our lab using a rodent model of early life pain suggests that inflammatory pain experienced on the day of birth blunts adult responses to stress- and pain-provoking stimuli, and dysregulates the hypothalamic pituitary adrenal (HPA) axis in part through a permanent upregulation in central endogenous opioid tone. This review focuses on the long-term impact of neonatal inflammatory pain on adult anxiety- and stress-related responses, and underlying neuroanatomical changes in the context of endogenous pain control and the HPA axis. These two systems are in a state of exaggerated developmental plasticity early in postnatal life, and work in concert to respond to noxious or aversive stimuli. We present empirical evidence from animal and clinical studies, and discuss historical perspectives underlying the lack of analgesia/anesthetic use for early life pain in the modern NICU.

    International Nuclear Information System (INIS)

    Davies, David B.

    2014-01-01

    This article contends that it is essential that new entrant countries into the nuclear energy industry have comprehensive nuclear legislation; it is less clear, however, whether new entrant countries find it essential to join any of the various international nuclear liability conventions, as some countries have been slow or resistant to the idea. This article will take a closer look at the potential influencing factors driving membership or non-membership in the CSC by a developing country. First, however, is a discussion of the basic principles of international nuclear third party liability, the CSC itself, developing countries' current participation in the various international nuclear liability conventions and the advantages and disadvantages of the CSC. The author's views regarding participation by a developing country in the CSC will also be presented. (author)

    Full Text Available Humans learned to exploit ruminants as a source of milk about 10,000 years ago. Since then, the use of domesticated ruminants as a source of milk and dairy products has expanded until today when the dairy industry has become one of the largest sectors in the modern food industry, including the spread at the present time to countries such as China and Japan. This review analyzes the reasons for this expansion and flourishing. As reviewed in detail, milk has numerous nutritional advantages, most important being almost an irreplaceable source of dietary calcium, hence justifying the effort required to increase its consumption. On the other hand, widespread lactose intolerance among the adult population is a considerable drawback to dairy-based foods consumption. Over the centuries, three factors allowed humans to overcome limitations imposed by lactose intolerance: (i mutations, which occurred in particular populations, most notably in the north European Celtic societies and African nomads, in which carriers of the lactose intolerance gene converted from being lactose intolerant to lactose tolerant; (ii the ability to develop low-lactose products such as cheese and yogurt; and (iii colon microbiome adaptation, which allow lactose intolerant individuals to overcome its intolerance. However, in a few examples in the last decade, modern dairy products, such as the popular and widespread bio-cultured yogurts, were suspected to be unsuitable for lactose intolerant peoples. In addition, the use of lactose and milk-derived products containing lactose in non-dairy products has become widespread. For these reasons, it is concluded that it might be important and helpful to label food that may contain lactose because such information will allow lactose intolerant groups to control lactose intake within the physiological limitations of ~12 g per a single meal.

    Full Text Available Objectives: The dangers of driving while under the influence of alcohol/drugs (DWI have been well established. Many countries have successfully reduced the incidence of DWI through effective law enforcement. We aim to explore the links between how law enforcement is perceived in cultures with different socioeconomic indicators. Our hypothesis is that social norms around definitions of what constitutes “right” vs. “deviant” behavior related to DWI directly contribute to the mode and success of law enforcement. Methods: Road safety professionals from six countries with different levels of DWI rates and enforcement strategies were interviewed regarding the expected local response to a case vignette. Sociodemographic, mortality, and economic indicators for each of these countries were extracted from different sources. Results: The professionals interviewed described a continuum ranging from unequivocal enforcement and punishment (Australia and Norway to inconsistent enforcement and punishment with the presence of many legal loopholes (Mexico and Brazil. For the six countries, no apparent correlation was identified purely between alcohol consumption and road traffic mortality. However, there seems to be a correlation between the time period of initial DWI legislation and current gross national income, perceptions of local safety, satisfaction with the local environment, and trust in the national government. Higher levels of these scores are seen in nations in which DWI laws were implemented prior to the 1960s. Conclusion: Better performing countries seem to have achieved a level of societal agreement that DWI is deviant, generating social stigma against DWI that allows legislation to be enforced. Lessons learned from these countries could help developing countries reduce morbidity and mortality associated with DWI.

    The toxicology of hydrogen sulfide (H{sub 2}S) and sour gas on the eye has a long history beginning at least with Ramazzini's observations [Ramazzini B. Diseases of Workers-De Morbis Artificum Diatriba-1713. Wright WC (trans). New York, C. Hafner Publishing Co Inc.; 1964. 98-99 pp.]. In contrast, a recent review by Alberta Health and Wellness (AHW Report) concluded that there is little evidence of eye irritation following short-term exposures to H{sub 2}S at concentrations up to 100 ppm and that the H{sub 2}S literature on the eye is a series of unsubstantiated claims reproduced in review articles dating back to the 1930s [Alberta Health and Wellness (AHW report). Health effects associated with short-term exposure to low levels of hydrogen sulfide: a technical review, Alberta Health and Wellness, October 2002, 81pp.]. In this paper, we evaluated this claim through a historical review of the toxicology of the eye. Ramazzini noted the effects of sewer gas on the eye [Ramazzini B. Diseases of Workers-De Morbis Artificum Diatriba-1713. Wright WC (trans). New York, C. Hafner Publishing Co Inc. 1964. 98-99 pp.]. Lehmann experimentally showed eye effects in men at 70-90 ppm H{sub 2}S and also in animals [Lehmann K. Experimentalle Studien uber den Einfluss technisch und hygienisch wichtiger Gase und Dampfe auf den Organismus. Arch Hyg 1892;14:135-189]. In 1923, Sayers, Mitchell and Yant reported eye effects in animals and men at 50 ppm H{sub 2}S. Barthelemy showed eye effects in animals and men at 20 ppm H{sub 2}S [Barthelemy HL. Ten years' experience with industrial hygiene in connection with the manufacture of viscose rayon. J Ind Hyg Toxicol 1939;21:141-51]. Masure experimentally showed that H{sub 2}S is the causative agent of eye impacts in animals and men [Masure R. La Keratoconjunctivite des filatures de viscose; etude clinique and experiementale.

    To review and summarize data provided by special issue authors regarding the education, training, and practice of neuropsychologists from 14 surveyed countries. A table was constructed to present an overview of variables of interest. There is considerable diversity among surveyed countries regarding the education and training required to enter practice as a clinical neuropsychologist. Clinical neuropsychologists are typically well compensated, at least in comparison to what constitutes an average salary in each country. Despite substantial variations in education and training pathways, and availability of neuropsychologists from country to country, two common areas for future development are suggested. First, identification, development, and measurement of core competencies for neuropsychological education and practice are needed that can serve as a unifying element for the world's clinical neuropsychologists. Second, greater emphasis on recognizing and addressing the need for assessment and treatment of diverse populations is needed if the world's citizens can hope to benefit from the expertise of practitioners in our field.

  10. Surrendering to the Big Picture: Historical and Legal Perspectives on Accountability in the Democratic Republic of Congo Following the Defeat of the March 23 Movement

    Full Text Available It remains to be seen whether the past few months will mark a genuine turning point in the conflict in eastern Democratic Republic of Congo (DRC, as the rebel faction March 23 Movement (M23 announced the end of its 20-month insurgency against the government on 5 November 2013. News of the rebel group’s surrender following its political and military defeat signals an important moment of hope and renewed prospects of peace and stability in a region prone to protracted armed conflict. However, long-term stability in the country and in the region will require a multi-faceted process consisting of comprehensive accountability for human rights violations that have been committed by all parties to the conflict. In this article, I will first lay out the historical context of the fighting and the root causes of conflict present long before M23’s entrance onto the scene as a splintered rebel faction so as to understand M23’s place within the country’s history of protracted violence. Next, I will explain the violations of international humanitarian and human rights law committed by all possible parties, including rebel and government groups, as well as individual criminal responsibility and corporate liability. Lastly, I will chart the pathways of criminal and social accountability at various levels of international and domestic justice systems to see how the DRC may continue to build long-term local stability in the eastern parts of the country by addressing the question of accountability for international crimes. This brief analysis aims to provide a broader understanding of a complex conflict beyond the defeat and disarmament of M23, albeit a key group in a region of contentious cross-border conflict.

    The Eastern Mediterranean region has the second highest number of road traffic injury mortality rates after the African region based on 2013 data, with road traffic injuries accounting for 27% of the total injury mortality in the region. Globally the number of road traffic deaths has plateaued despite an increase in motorization, but it is uncertain whether this applies to the Region. This study investigated the regional trends in both road traffic injury mortality and morbidity and examined country-based differences considering on income level, categories of road users, and gender distribution. Register-based ecological study linking data from Global Burden of Disease Study with the United Nations Statistics Division for population and World Bank definition for country income level. Road traffic injury mortality rates and disability-adjusted life years were compiled for all ages at country level in 1995, 2005, 2015 and combined for a regional average (n = 22) and a global average (n = 122). The data were stratified by country economic level, road user category and gender. Road traffic injury mortality rates in the Region were higher than the global average for all three reference years but suggest a downward trend. In 2015 mortality rates were more than twice as high in low and high income countries compared to global income averages and motor vehicle occupants had a 3-fold greater mortality than the global average. Severe injuries decreased by more than half for high/middle income countries but remained high for low income countries; three times higher for males than females. Despite a potential downward trend, inequalities in road traffic injury mortality and morbidity burden remain high in the Eastern Mediterranean region. Action needs to be intensified and targeted to implement and enforce safety measures that prevent and mitigate severe motor vehicle crashes in high income countries especially and invest in efforts to promote public, active transport

  14. Is the Region of Visegrad Countries on the Track to the Euro Area? Recent Evidence from the Real Convergence Perspective

    2014-09-01

    Full Text Available After enlargement of the European Union and subsequently joining of a new member states to the euro area, the question of economic convergence attracted considerable research interest. This paper adopts three alternative concepts to examine the level and trend of convergence in the Visegrad countries (Czech Republic, Hungary, Poland, Slovakia. We concurrently estimate the β-convergence, σ-convergence and business cycle synchronization to find out whether all countries are on the way towards higher convergence with the euro area. The results suggest that convergence of all countries has been increasing. However, the recent acceleration of the convergence process is caused mainly by external shocks in the form of the financial crisis and following economic slowdowns. Hence, the current level of convergence in the Visegrad countries cannot be considered as fully adequate.

  16. Power Relations in Parinoush Sani’ee’s Sahm-e Man (The Book of Fate: A New-historical Perspective

    Directory of Open Access Journals (Sweden)

    Ali Taghizadeh

    2015-12-01

    Full Text Available This paper is an attempt to critically analyze Parinoush Sani’ee’s Sahm-e Man (translated into English as The Book of Fate from a New-historical perspective. Beginning from before the 1979 Iranian Revolution, and going forward through the reign of the Islamic Republic to the current years, the time-line of the story shows five decades of changing fortunes of Sani’ee’s main character. Reading her book in the light of New-historicism, this paper tries to show how the story reflects Foucauldian notions of resistance, power relations, normalization, and self-formation in the five phases of Massoumeh’s life. Considering Foucault’s arguments on how power imposes ideology on the citizens, the paper also tries to reflect how it changes in each phase of Massoumeh’s life and how it normalizes her to make her into a docile subject whom it can best control. Added to that, the paper tries to demonstrate her success in resisting the power and acquiring an ethical self through practicing a care for her ‘self’. However, in spite of all her resistances to power and normalization, in the last phase of the story when the novel’s discourse is more emotional, Massoumeh gives up resistance and accepts normalization, and for the sake of her children’s satisfaction, rejects Saiid’s proposal, and like most of the widows in her age, decides to live alone to the end of her life.

  17. The long-term impact of early life pain on adult responses to anxiety and stress: Historical perspectives and empirical evidence.

    Victoria, Nicole C; Murphy, Anne Z

    2016-01-01

    Approximately 1 in 6 infants are born prematurely each year. Typically, these infants spend 25 days in the Neonatal Intensive Care Unit (NICU) where they experience 10-18 painful and inflammatory procedures each day. Remarkably, pre-emptive analgesics and/or anesthesia are administered less than 25% of the time. Unalleviated pain during the perinatal period is associated with permanent decreases in pain sensitivity, blunted cortisol responses and high rates of neuropsychiatric disorders. To date, the mechanism(s) by which these long-term changes in stress and pain behavior occur, and whether such alterations can be prevented by appropriate analgesia at the time of insult, remains unclear. Work in our lab using a rodent model of early life pain suggests that inflammatory pain experienced on the day of birth blunts adult responses to stress- and pain-provoking stimuli, and dysregulates the hypothalamic pituitary adrenal (HPA) axis in part through a permanent upregulation in central endogenous opioid tone. This review focuses on the long-term impact of neonatal inflammatory pain on adult anxiety- and stress-related responses, and underlying neuroanatomical changes in the context of endogenous pain control and the HPA axis. These two systems are in a state of exaggerated developmental plasticity early in postnatal life, and work in concert to respond to noxious or aversive stimuli. We present empirical evidence from animal and clinical studies, and discuss historical perspectives underlying the lack of analgesia/anesthetic use for early life pain in the modern NICU.

  18. UK and Twenty Comparable Countries GDP-Expenditure-on-Health 1980-2013: The Historic and Continued Low Priority of UK Health-Related Expenditure.

    Harding, Andrew J E; Pritchard, Colin

    2016-07-10

    It is well-established that for a considerable period the United Kingdom has spent proportionally less of its gross domestic product (GDP) on health-related services than almost any other comparable country. Average European spending on health (as a % of GDP) in the period 1980 to 2013 has been 19% higher than the United Kingdom, indicating that comparable countries give far greater fiscal priority to its health services, irrespective of its actual fiscal value or configuration. While the UK National Health Service (NHS) is a comparatively lean healthcare system, it is often regarded to be at a 'crisis' point on account of low levels of funding. Indeed, many state that currently the NHS has a sizeable funding gap, in part due to its recently reduced GDP devoted to health but mainly the challenges around increases in longevity, expectation and new medical costs. The right level of health funding is a political value judgement. As the data in this paper outline, if the UK 'afforded' the same proportional level of funding as the mean average European country, total expenditure would currently increase by one-fifth. © 2016 by Kerman University of Medical Sciences.

    2001-03-01

    An examination of the situation in the Mediterranean countries indicates that the demand for energy will surge to more than 1100 million tonnes of petroleum equivalent in 2010, an increase from the 800 million of tonnes of petroleum equivalent in 1998. The supply of primary energy is mainly provided by Algeria, Egypt, and Lybia. The challenge is to ensure the long-term stability of the energy exchanges between producing countries and their customers. In this regard, the Maghreb countries are in a favorable position, where the distribution systems are fairly well developed. The power distribution systems between these countries are interconnected (in addition to Morocco-Spain), and there are pipelines connecting Algeria-Tunisia-Italy, and Algeria-Morocco-Spain which reinforce the cooperation efforts. Other projects are in the planning stages to interconnect Algeria-Spain, Algeria-Sardinia-Italy, and Lybia-Italy. The policies in place in the countries located south of the Mediterranean Sea vary somewhat. In Morocco, an institutional reform of the electricity sector took place in 1995, where electricity production was effected in partnerships rather than being through leases. Tunisia opted for a more radical approach with the Build-Own-Operate (BOO). Algeria aims at reforming regulations concerning electricity, gas and hydrocarbons distribution in an attempt to introduce competitiveness and favor foreign investments. Lybia is considering a reorganization of its electricity sector towards the implementation of market openness. Egypt implemented a vast program of Independent Energy Producers. Turkey adopted the Build-Operate-Transfer (BOT) approach to electricity. South of the Mediterranean Sea, private electricity production is already a reality. The author briefly described the situation in Algeria in greater detail. 2 figs.

  20. Confidence in Government and Attitudes toward Bribery: A Country-Cluster Analysis of Demographic and Religiosity Perspectives

    2017-01-01

    Full Text Available In this study, we try to classify the countries by the levels of confidence in government and attitudes toward accepting bribery by using the data of the sixth wave (2010–2014 of the World Values Survey (WVS. We are also interested in which demographic, attitudinal, and religiosity variables affect each class of countries. For these purposes cluster analysis, linear regression analysis, and ordered logistic regression analysis were used. The study found that countries could be grouped into two clusters which had varying levels of opposition to bribe taking and confidence in government. Another finding was that certain demographic, attitudinal, and religiosity variables that were significant in one cluster might not be significant in another cluster.
