    The present study deals with dissipative future universe without big rip in context of Eckart formalism. The generalised chaplygin gas, characterised by equaction of state $p=-\\frac{A}{\\rho^\\frac{1}{\\alpha}}$, has been considered as a model for dark energy due to its dark-energy-like evolution at late time. It is demonstrated that, if the cosmic dark energy behaves like a fluid as well as chaplygin gas simultaneously then the big rip problem does not arise and the scale factor is found to be regular for all time.

    Giving the opening keynote speech at last year's Healthcare Estates conference, Mike Hobbs, managing director of Carillion Health, drew on his 25 years' experience to discuss how innovation can help drive the greater efficiency and productivity that the NHS is charged with delivering, in the process cutting costs at a time when the service faces the tightest economic pressures in its history. He argued that as we enter a new world of 'Big data', the availability of accurate, comprehensive data on which to base key decisions will be the major enabler for the design and construction of high quality healthcare facilities in the future. It will equally be key, he said, to their efficient, low-cost, and optimal utilisation to provide the higher 'productivity' the Government says is essential.

  10. Interoperability Outlook in the Big Data Future

    2015-12-01

    The establishment of distributed active archive centers (DAACs) as data warehouses and the standardization of file format by NASA's Earth Observing System Data Information System (EOSDIS) had doubtlessly propelled interoperability of NASA Earth science data to unprecedented heights in the 1990s. However, we obviously still feel wanting two decades later. We believe the inadequate interoperability we experience is a result of the the current practice that data are first packaged into files before distribution and only the metadata of these files are cataloged into databases and become searchable. Data therefore cannot be efficiently filtered. Any extensive study thus requires downloading large volumes of data files to a local system for processing and analysis.The need to download data not only creates duplication and inefficiency but also further impedes interoperability, because the analysis has to be performed locally by individual researchers in individual institutions. Each institution or researcher often has its/his/her own preference in the choice of data management practice as well as programming languages. Analysis results (derived data) so produced are thus subject to the differences of these practices, which later form formidable barriers to interoperability. A number of Big Data technologies are currently being examined and tested to address Big Earth Data issues. These technologies share one common characteristics: exploiting compute and storage affinity to more efficiently analyze large volumes and great varieties of data. Distributed active "archive" centers are likely to evolve into distributed active "analysis" centers, which not only archive data but also provide analysis service right where the data reside. "Analysis" will become the more visible function of these centers. It is thus reasonable to expect interoperability to improve because analysis, in addition to data, becomes more centralized. Within a "distributed active analysis center

    The presented case study by the Fraunhofer Institute ISE shows that the market for stationary electrochemical storage prices are currently too high for economical operation. In winter, a battery in Germany is not always fully loaded because of low sunlight. Therefore, the combination of a battery with a PV system at this time of year does not have enough full cycles to be economical. For more complete cycles of the year and consequently lower specific storage cost wind turbines or other power generators can be connected. Since - in contrast to lead acid batteries - there is no experience with long-term storage in lithium and redox flow batteries, this study is based on current forecasts. Compared to lithium-ion batteries, lead-acid and redox flow batteries have a lower efficiency, so that the investment costs of the battery must be lower because fewer savings can be achieved. Especially for short-term storage, the production costs must be reduced. The cost reduction potential of redox flow and lithium-ion batteries is due to the current technical state of development compared to lead acid batteries very high. This means that an economic operation in the future is possible with constant development of electricity and battery prices. [German] Die vorgestellte Fallstudie des Fraunhofer Instituts ISE zeigt, dass die Marktpreise fuer stationaere elektrochemische Speicher aktuell fuer einen wirtschaftlichen Betrieb zu hoch sind. Im Winter wird eine Batterie in Deutschland aufgrund der niedrigen Sonneneinstrahlung nicht immer komplett geladen. Daher hat die Kombination eines Speichers mit einer PV-Anlage zu dieser Jahreszeit nicht genug Vollzyklen, um wirtschaftlich zu sein. Fuer mehr Vollzyklen im Jahr und demzufolge geringere spezifische Speicherkosten koennen Windkraftanlagen oder andere Stromerzeuger angeschlossen werden. Da es- im Gegensatz zu Bleisaeure- Batterien - noch keine Erfahrung mit Langzeitspeichern im Bereich Lithium und Redox-Flow gibt, beruht diese

    "Big data" is a new buzzword. The point is not to be dazzled by the volume of data, but rather to analyze it, and convert it into insights, innovations, and business value. There are also real differences between conventional analytics and big data. In this article, we show some results of big data analysis using open DPC (Diagnosis Procedure Combination) data in areas of the central part of JAPAN: Toyama, Ishikawa, Fukui, Nagano, Gifu, Aichi, Shizuoka, and Mie Prefectures. These 8 prefectures contain 51 medical administration areas called the second medical area. By applying big data analysis techniques such as k-means, hierarchical clustering, and self-organizing maps to DPC data, we can visualize the disease structure and detect similarities or variations among the 51 second medical areas. The combination of a big data analysis technique and open DPC data is a very powerful method to depict real figures on patient distribution in Japan.

    Rapid growth in the amount of data that is electronically recorded as part of routine clinical operations has generated great interest in the use of Big Data methodologies to address clinical and research questions. These methods can efficiently analyze and deliver insights from high-volume, high-variety, and high-growth rate datasets generated across the continuum of care, thereby forgoing the time, cost, and effort of more focused and controlled hypothesis-driven research. By virtue of an existing robust information technology infrastructure and years of archived digital data, radiology departments are particularly well positioned to take advantage of emerging Big Data techniques. In this review, we describe four areas in which Big Data is poised to have an immediate impact on radiology practice, research, and operations. In addition, we provide an overview of the Big Data adoption cycle and describe how academic radiology departments can promote Big Data development.

    The aim of this paper is to present the state of the science concerning issues in end-of-life (EOL) care which have an impact on intensive care nurses possibilities to provide nursing care for dying patients and their families. The perspective of families is also illuminated and finally ethical challenges in the present and for the future are discussed. The literature review revealed that the problem areas nurses report concerning EOL care have been the same over three decades. Most problems are related to inter-disciplinary collaboration and communication with the medical profession about the transition from cure to comfort care. Nurses need enhanced communication skills in their role as the patient's advocate. Education in EOL care and a supportive environment are prerequisites for providing EOL care. Losing a loved one in the ICU is a stressful experience for close relatives and nursing care has a profound impact on families' memories of the EOL care given to their loved ones. It is therefore important that ICU nurses are aware of families' needs when a loved one is dying and that follow-up services are appreciated by bereaved family members. Ethical challenges are related to changed sedation practices, organ donation, globalisation and cultural sensitivity. PMID:25218688

    Nutzung weltweit unangefochten die Fuehrungsrolle erlangt. Fuer konventionelle Antriebe und Kraftstoffe wurde dabei ein hoher Standard erreicht, der sich durch optimierte Verbrennung, aufwaendige Abgasnachbehandlung und dementsprechend niedrige klassische Abgasemissionen auszeichnet. Die Abhaengigkeit von den eingeschraenkt verfuegbaren Oelvorkommen sowie die Nachteile bei der Verbrennung fossiler Energietraeger infolge von Treibhausgasemissionen haben die Diskussion zu diesen bislang als optimal angesehenen Kraftstoffen intensiviert. Entsprechend wird nach anderen Kraftstoffen bzw. Antriebsformen fuer den Strassenverkehr gesucht. Einbezogen werden dabei oekologische und oekonomische Kriterien sowie die Ressourcenverfuegbarkeit zur Erzielung eines Gesamtoptimums des Kraftstoffsystems. Schluessel zur 'Entkarbonisierung' des Kraftstoffes kann langfristig der Einsatz von Wasserstoff als Treibstoff sein - unter der Voraussetzung einer insgesamt emissionsarmen Erzeugungskette fuer die Bereitstellung des Wasserstoffs. Die Entwicklung an Wasserstoff-Fahrzeug-Prototypen bei BMW wird seit 20 Jahren verfolgt. Mit dem BMW 750hL konnte im Jahr 2000 eine seriennahe Flotte von 15 fahrbereiten Pkw aufgebaut werden. Im Jahr 2001 stellte BMW mit der Modellreihe 745h die sechste Generation vor und damit ein erstmals unter seriennahen Bedingungen entwickeltes Fahrzeug. Alle Fahrzeug-Serien sind mit einem Wasserstoff-Kryotank ausgestattet und fuer bivalenten Betrieb ausgelegt (Wasserstoff/Benzin). Wesentliche technische Entwicklungsaufgabe ist die Speicherung des Kraftstoffes Wasserstoff. Aufgrund seiner physikalisch-chemischen Eigenschaften sind moderne Kryo-Tanks fuer Fluessigwasserstoff entwickelt worden. Im Rahmen der Verkehrswirtschaftlichen Energiestrategie haben sich fuehrende Unternehmen mit Unterstuetzung der Bundesregierung zusammengeschlossen, um an einer konzertierten Einfuehrungsstrategie fuer den Kraftstoff Wasserstoff zu arbeiten.

    The intense competition that accompanied the growth of internet-based companies ushered in the era of 'big data' characterized by major innovations in processing of very large amounts of data and the application of advanced analytics including data mining and machine learning. Healthcare is on the cusp of its own era of big data, catalyzed by the changing regulatory and competitive environments, fueled by growing adoption of electronic health records, as well as efforts to integrate medical claims, electronic health records and other novel data sources. Applying the lessons from big data pioneers will require healthcare and life science organizations to make investments in new hardware and software, as well as in individuals with different skills. For life science companies, this will impact the entire pharmaceutical value chain from early research to postcommercialization support. More generally, this will revolutionize comparative effectiveness research. PMID:24645690

For life science companies, this will impact the entire pharmaceutical value chain from early research to postcommercialization support. More generally, this will revolutionize comparative effectiveness research.

    Full Text Available Demand and spurt in collections and accumulation of data has coined new term “Big Data” has begun. Accidently, incidentally and by interaction of people, information so called data is massively generated. This BIG DATA is to be smartly and effectively used Computer scientists, physicists, economists, mathematicians, political scientists, bio-informaticists, sociologists and many Variety of Intellegesia debate over the potential benefits and costs of analysing information from Twitter, Google, Facebook, Wikipedia and every space where large groups of people leave digital traces and deposit data. Given the rise of Big Data as both a phenomenon and a methodological persuasion, it is time to start critically interrogating this phenomenon, its assumptions and its biases. Big data, which refers to the data sets that are too big to be handled using the existing database management tools, are emerging in many important applications, such as Internet search, business informatics, social networks, social media, genomics, and meteorology. Big data presents a grand challenge for database and data analytics research. This paper is a blend of non-technical and introductory-level technical detail, ideal for the novice. We conclude with some technical challenges as well as the solutions that can be used to these challenges. Big Data differs from other data with five characteristics like volume, variety, value, velocity and complexity. The article will focus on some current and future cases and causes for BIG DATA.

    2016-01-01

    Until recently tactical analysis in elite soccer were based on observational data using variables which discard most contextual information. Analyses of team tactics require however detailed data from various sources including technical skill, individual physiological performance, and team formations among others to represent the complex processes underlying team tactical behavior. Accordingly, little is known about how these different factors influence team tactical behavior in elite soccer. In parts, this has also been due to the lack of available data. Increasingly however, detailed game logs obtained through next-generation tracking technologies in addition to physiological training data collected through novel miniature sensor technologies have become available for research. This leads however to the opposite problem where the shear amount of data becomes an obstacle in itself as methodological guidelines as well as theoretical modelling of tactical decision making in team sports is lacking. The present paper discusses how big data and modern machine learning technologies may help to address these issues and aid in developing a theoretical model for tactical decision making in team sports. As experience from medical applications show, significant organizational obstacles regarding data governance and access to technologies must be overcome first. The present work discusses these issues with respect to tactical analyses in elite soccer and propose a technological stack which aims to introduce big data technologies into elite soccer research. The proposed approach could also serve as a guideline for other sports science domains as increasing data size is becoming a wide-spread phenomenon. PMID:27610328

    What means a sustainable energy sector? The advancement of innovative technologies to decrease the dependency of fossil, dwindling fuels and the prevention of greenhouse gases? Sure. Is in Germany to this topic really volition of policy and economy? The answer should be: partly. Renewable Energies are in a continued increase due to the Renewable Energy Sources Act, the fuel cell is in contrast an ineffectual initiative, the hold on the nuclear industry is a return to the last century. Fuel cells are one of the technologies with the greatest potential: Whether for the home-supply, for industry- or mobile applications (e-mobility), fuel cells are perfect heat- and electricity plants, scalable for a large power range. In conjunction with the supply of pure- or chemical bounded hydrogen by renewable energies, fuel cells could be the plants of the future. Finally the technology must be controlled. This occurred constricted, there is (yet) no durability and cost effectiveness given. Here it is the challenge of the policy, the r and d and the industry respectively the manufacturers to develop this technology to marketability with the help of target-oriented research programs and subsidies or to fail.

    2006-05-01

    Full Text Available [english] Medical education is presently unveiling trends, which also dominate other fields of higher education. Within the framework of internationalisation and globalisation, and driven by developments in information and communication technology and the pronounced migration of medical doctors, one has observed consequences such as commercialisation and privatisation. This, in turn, has engendered a quality assurance reaction with focus on standardisation and accreditation. The Bologna Declaration and Process can be seen as part of this new quality concern, but also raises problems for medical education regarding the two-cycle (bachelor and master degrees system. Standard setting in medical education in Europe took its start with the EU Medical Directive, which has essentially not been changed in 30 years. The increasing internationalisation of medical education, which shows a number of innovative trends, but which also unveils many problems and challenges, emphasises the role of the WFME Global Standards Programme launched in 1997. The Trilogy of Global Standards, covering the continuum of medical education, has been adopted in all parts of the world. The Standards for Basic Medical Education are used in reform programmes in many medical schools and are now also being incorporated in definition of national accreditation standards. This development has recently been strengthened in the WHO/WFME Strategic Partnership to Improve Medical Education. One practical result of this collaboration was the development of WHO/WFME Guidelines for Accreditation of Basic Medical Education. A Task Force under the new EU Thematic Network MEDINE is now working with definition of European accreditation standards using the WFME Global Standards as a template. The immediate perspective will be establishment of national accreditation systems in the European region and there is probably no need at the moment for a common accreditation system in Europe.

    The third Ministerial Conference of the World Trade Organisation (WTO) took place in Seattle (USA) from November 30{sup th} to December 3{sup rd} 1999. WTO members failed to agree on an agenda for a new round of trade-negotiation that should also include environmental and sustainability aspects. The Seattle Ministerial Conference provoked massive protests from non-governmental organisations (NGO) dealing with environment and development issues. They see the GATT/WTO regime - and globalisation in general - as a threat to their concerns. Against this background, the study analyses possibilities for the integration of environmental and sustainability aspects into upcoming WTO-negotiations. The focus is on views and proposals from international NGOs and critical scientists. First, the study deals with current and potential future areas of conflicts between environmental and trade policies. Furthermore, the environmental aspects of trade liberalisation in specific sectors and regulatory fields are discussed, which are currently negotiated in the WTO (agriculture, services) or which should be included in further negotiations (forest products, investment, etc.). The study moves on to an account of the WTO-Conference in Seattle from an environmental perspective and demonstrate a multitude of factors contributed to the failure of the conference. (orig.)

    Scheen, A J

    2015-01-01

    The increasing interest for personalized medicine evolves together with two major technological advances. First, the new-generation, rapid and less expensive, DNA sequencing method, combined with remarkable progresses in molecular biology leading to the post-genomic era (transcriptomics, proteomics, metabolomics). Second, the refinement of computing tools (IT), which allows the immediate analysis of a huge amount of data (especially, those resulting from the omics approaches) and, thus, creates a new universe for medical research, that of analyzed by computerized modelling. This article for scientific communication and popularization briefly describes the main advances in these two fields of interest. These technological progresses are combined with those occurring in communication, which makes possible the development of artificial intelligence. These major advances will most probably represent the grounds of the future personalized medicine.

    Hogg, R. S.; Takaro, T.; Miller, C.; Hogg, E.; Anema, A.; Gislason, M.; Parkes, M.

    Background: Ecological footprints assess the land and water a population needs to procure its resources and handle its waste. Measures derived from these footprints look at a population's ecological overshoot rather than weighting the population to its footprint. The aim of this study was to examine the latter approach by determining what the current and future weighted world population, by income gradient, would be if everyone lived within the boundary of 1.8 hectares per person. Methods: Country-specific ecological footprints and populations for 2007 were obtained from the Global Footprint Network (www.footprintnetwork.org); and projected populations were collected from US Census Bureau (www.census.gov). Footprint growth to 2050 was based on a business as usual approach developed by Kitzes et al. in Phil. Trans. R. Soc. B (2008). Weighted population estimates were derived by multiplying actual population by the ratio of the country's footprint to overall boundary of 1.8 hectares per person. Results: The weighted global population increased by 2.4 billion people (37%) in 2007 based on our adjustment. High and middle-income country populations increased, by 242% and 10%, respectively, while low-income country populations decreased by 33%. The weighed global population in 2050 increased by 10.1 billion with the majority of this growth occurring in high-income countries -- 437% versus 67% and 9% respectively for medium and low-income countries. Conclusions: Our study showed that current and future global weighted demographic and ecological impact would be felt mainly in high-income countries even though actual population growth would occur mainly in low and middle-income countries.

    Nanomaterials are becoming increasingly widespread in consumer technologies, but there is global concern about the toxicity of nanomaterials to humans and the environment as they move rapidly from the research laboratory to the market place. With this in mind, it makes sense to intensify the nanochemistry community's global research effort on the synthesis and study of nanoparticles that are purportedly "green". One potentially green nanoparticle that seems to be a most promising candidate in this context is silicon, whose appealing optical, optoelectronic, photonic, and biomedical attributes are recently gaining much attention. In this paper, we outline some of our recent contributions to the development of the growing field of silicon nanocrystals (ncSi) in order to stress the importance of continued study of ncSi as a green alternative to the archetypal semiconductor nanocrystals like CdSe, InAs, and PbS. While a variety of developments in synthetic methods, characterization techniques, and applications have been reported in recent years, the ability to prepare colloidally-stable monodisperse ncSi samples may prove to have the largest impact on the field, as it opens the door to study and access the tunable size-dependent properties of ncSi. Here, we summarize our recent contributions in size-separation methods to achieve monodisperse samples, the characterization of size-dependant property trends, the development of ncSi applications, and their potential impact on the promising future of ncSi.

    Full Text Available The main objective of this contribution is to examine the developments and challenges of African Studies in Poland, with a special focus on the fields of political science and economics. The article demonstrates that the historical development of Polish African Studies has shaped, but also limited, the ongoing debate concerning its nature and objectives. The paper discusses two competing interpretations of the substance of African Studies and deals with the current challenges and hopes of the Polish academic community studying Africa. It argues that while the field of African Studies usually serves as a common denominator and a type of “area” platform where various scholars doing research on Africa can share their findings, this does not necessarily lead to integration within the community and/or to better communication. Quite paradoxically, the diagnosis of Polish African Studies presented almost 50 years ago by Jan Halpern can still be applied today: “Generally speaking, Polish scholars in African subjects feel that the further progress of their work demands, above all, a better coordination of research and closer contact with specialists abroad.”Dieser Beitrag widmet sich der Entwicklung der Afrikaforschung in Polen und den Herausforderungen, vor denen sie steht, unter besonderer Berücksichtigung der Politik- und Wirtschaftswissenschaft.

    Full Text Available Using the metaphor of the elephant and the three blind men, this paper discusses some elements of the scholarly debate on the postcolonial turn in academia, in and of Africa, and in anthropology in particular. It is a part of the context in which anthropology remains unpopular among many African intellectuals. How do local knowledge practices take up existential issues and epistemological perspectives that may interrogate and enrich more global transcultural debates and scholarly reflexivity? Many an anthropologist still resists opening his or her mind up to life-worlds unfolding themselves through the interplay between everyday practice and the manifold actions and messages of humans, ancestors and non-human agents in sites of emerging meaning-production and innovative world-making. African anthropologists seeking recognition find themselves contested or dismissed by fellow anthropologists for doing “native”, “self” or “insider” anthropology, and are sometimes accused of perpetuating colonial epistemologies and subservience by fellow African scholars who are committed to scholarship driven by the need to valorise ways of being and knowing endogenous to Africa. This essay calls on anthropologists studying Africa to reflect creative diversity and reflexivity in the conceptualisation and implementation of research projects, as well as in how they provide for co-production, collaboration and co-implication within anthropology across and beyond disciplines.Unter Rückgriff auf die Fabel vom Elefanten und den drei weisen Männern diskutiert dieser Beitrag einige Elemente der Debatte zur postkolonialen Wende in der Wissenschaft – innerhalb und außerhalb Afrikas und insbesondere in Bezug auf die Ethnologie.

    In order to meet the new powertrain requirements, Daimler AG is working not only to advance the combustion engine, but also to leverage all future technologies such as the electric drive, battery, and fuel cell. In the short to mid term, however, it is the combustion engine that will remain in the lead assuming that efficiency continues to improve. By reducing internal friction, up to 25 percent of losses can be mitigated during partial-load operation, which spotlights friction as a variable that cannot be overlooked. Motivated by this knowledge, Daimler has developed NANOSLIDE for cylinder liners, a technology that is capable of reducing friction in the piston assembly by up to 50 percent. In practical terms, this corresponds to a CO{sub 2} savings potential of 3 percent for a V6 diesel engine. The effects of friction-reducing measures have been demonstrated by referring to the M 276 V6 gasoline engine, which not only exhibit better performance with respect to the FEV tolerance band, but also optimized friction levels that, in total, are up to 31 percent lower than those of the predecessor engines. In addition to providing higher torque and output as well as complying with emissions requirements, these engines also consume up to 24 percent less fuel. The total gains achieved by integrating friction-reducing measures thus play an important role in characterizing the major advancements that have recently been made to reduce fuel consumption and set the stage for tomorrow's engines.

    Since 1990s up to now, climate and environmental science communication has gradually become a priority of policy programmes, a consolidated subject of training and education, a developed and greatly expanded field of professional practices. However, in contrast to this very fast evolution there is presumably a deficit in terms of research and reflection on objective tools to assess the quality and impact of communication activities. The quality of communication in the field of science has become more and more challenging due to the fact that the role of traditional mediators (e.g. well reputed newspapers or broadcasters, science museums), that used to be considered quality guarantors, has now become marginal. Today, a new generation of communication professionals tend to be employed by research institutes to respond to a stronger request to develop accountable research projects, to increase transparency and trust and to disseminate and implementation of research findings. This research aims to understand how communication strategies, addressed to the general public, can optimise the impact of research findings in hydrology for resilient cities. The research will greatly benefit from the development of automated analysis of unstructured Big Data that allows the exploration of huge amounts of digital communication data: blogs, social networks postings, public speeches, press releases, publications, articles... Furthermore, these techniques facilitate the crossing of socio-economic and physical-environmental data and possibly lead to the identification of existing correlations. Case studies correspond to those of several research projects under the umbrella of the Chair "Hydrology for resilient cities" aimed to develop and test new solutions in urban hydrology that will contribute to the resilience of our cities to extreme weather. This research was initiated in the framework of the Interreg IVB project RAINGAIN and pursued in the project Blue Green Dream of the EU

    Hydrogen today appears as a beacon of hope. Water is in sufficient supply, and hydrogen can be produced by electrolysis. Excess power, e.g. from solar and wind power plants, can be stored in the form of hydrogen. The stored chemical energy can then be converted into electric power with the aid of fuel cells. The by-product is water instead of climate-relevant CO2. Of course, both the electrolysis and the hydrogen storage must be optimised if fuel cells are to be able to compete with established technologies like petroleum or internal combustion engines. Attempts are therefore being made to copy nature (biomimetry) or to use metal hydrides for hydrogen storage. [German] Wasserstoff erscheint heute als Hoffnungstraeger, weil Wasser reichlich vorhanden ist und er durch Elektrolyse daraus gewonnen kann. Dort wo Stromueberschuesse produziert werden - wie z.B. bei Sonnen- und Windenergie - kann man sie ''zwischenlagern'', indem man sie fuer die Elektrolyse von Wasser nutzt und so die Energie in Form von Wasserstoff speichern. Man kann mit Hilfe von Brennstoffzellen die gespeicherte chemische Energie in elektrische Energie umwandeln. Dabei entsteht nur Wasser als Abfallprodukt und nicht das Treibhausgas CO{sub 2}. Natuerlich muss sowohl die Elektrolyse als auch die Wasserstoffspeicherung noch weiterentwickelt werden, um mit den etablierten Verfahren der Energieversorgung wie dem System Erdoelindustrie/Verbrennungsmotor konkurrieren zu koennen. So versucht man z.B. bei der Wasserstoffproduktion die Natur zu kopieren (Biomimetrie) oder Wasserstoffspeicherung Metallhydride einzusetzen.

    These are the results of two surveys of relatives, and others who knew people who had died, describing events in the year before death and their views on the time of the person's death. Those surveyed were identified from death certificates in England. The main focus is on a sample of 3696 people dying in 1990 in 20 health authorities, with supporting analysis from an earlier national sample of 639 people dying in 1987. Variation in peoples' views about whether an earlier death would have been better is reported, in the context of debate about euthanasia. Spouses were less likely than others to feel that it would have been better if the person had died earlier, and this held true even when controlling for the deceaseds' levels of pain, distress, dependency and age. Spouses were more likely than others to say that a later death would have been better, though not in cases where the deceased was reported as having said they wanted to die sooner. Spouses were influenced by the loss which the death of the person represented for them, being more likely than others to say they missed the person who died a great deal, and feel loneliness was a big problem. Non spouses (children and other relatives of the deceased, friends, neighbours and a few officials) on the other hand were more likely than spouses to say an earlier death would have been better, even when levels of pain, distress, dependency and age were controlled for.(ABSTRACT TRUNCATED AT 250 WORDS)

    The increasing availability and growth rate of biomedical information, also known as 'big data', provides an opportunity for future personalized medicine programs that will significantly improve patient care. Recent advances in information technology (IT) applied to biomedicine are changing the landscape of privacy and personal information, with patients getting more control of their health information. Conceivably, big data analytics is already impacting health decisions and patient care; however, specific challenges need to be addressed to integrate current discoveries into medical practice. In this article, I will discuss the major breakthroughs achieved in combining omics and clinical health data in terms of their application to personalized medicine. I will also review the challenges associated with using big data in biomedicine and translational science. PMID:24183925

    Full Text Available [english] Since several years risk-based monitoring is the new “magic bullet” for improvement in clinical research. Lots of authors in clinical research ranging from industry and academia to authorities are keen on demonstrating better monitoring-efficiency by reducing monitoring visits, monitoring time on site, monitoring costs and so on, always arguing with the use of risk-based monitoring principles. Mostly forgotten is the fact, that the use of risk-based monitoring is only adequate if all mandatory prerequisites at site and for the monitor and the sponsor are fulfilled.Based on the relevant chapter in ICH GCP (International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use – Good Clinical Practice this publication takes a holistic approach by identifying and describing the requirements for future monitoring and the use of risk-based monitoring. As the authors are operational managers as well as QA (Quality Assurance experts, both aspects are represented to come up with efficient and qualitative ways of future monitoring according to ICH GCP.[german] Seit einigen Jahren wird von den verschiedensten Autoren – aus den industriellen, akademischen oder behördlichen Bereichen der Klinischen Forschung – das Risiko-basierte Monitoring fast wie eine Wunderformel beschworen und bewertet. Um die damit erzielten Verbesserungsmöglichkeiten nachzuweisen, werden generelle Effizienzsteigerungen und Kosteneinsparungen bei den unterschiedlichen Monitoringaktivitäten beschrieben: weniger Monitoringbesuche am Zentrum, reduzierte Dauer der Monitoringbesuche oder mehr technisch unterstütztes Monitoring.Direkt oder indirekt enthalten die Publikationen oft auch Hinweise auf die notwendigen Voraussetzungen sowohl beim Zentrum als auch bei Monitor und Sponsor, um Risiko-basiertes Monitoring adequat einzusetzen; bei der Umsetzung werden diese Bedingungen gerne vergessen.Durch den ganzheitlichen

    2016-06-01

    Well-designed astronomical surveys are powerful and have consistently been keystones of scientific progress. The Byurakan Surveys using a Schmidt telescope with an objective prism produced a list of about 3000 UV-excess Markarian galaxies but these objects have stimulated an enormous amount of further study and appear in over 16,000 publications. The CFHT Legacy Surveys used a wide-field imager to cover thousands of square degrees and those surveys are mentioned in over 1100 publications since 2002. Both ground and space-based astronomy have been increasing their investments in survey work. Survey instrumentation strives toward fair samples and large sky coverage and therefore strives to produce massive datasets. Thus we are faced with the "big data" problem in astronomy. Survey datasets require specialized approaches to data management. Big data places additional challenging requirements for data management. If the term "big data" is defined as data collections that are too large to move then there are profound implications for the infrastructure that supports big data science. The current model of data centres is obsolete. In the era of big data the central problem is how to create architectures that effectively manage the relationship between data collections, networks, processing capabilities, and software, given the science requirements of the projects that need to be executed. A stand alone data silo cannot support big data science. I'll describe the current efforts of the Canadian community to deal with this situation and our successes and failures. I'll talk about how we are planning in the next decade to try to create a workable and adaptable solution to support big data science.

    New engines for civilian aviation are to emit substantially fewer pollutants in the future. Engineers want to ensure this with so-called lean combustion chambers in jet engines. These chambers combust the air-kerosene-mixture at low temperatures and thus reduce the emissions of nitrogen oxides. At the high pressure combustion chamber test stand 1 of the institute for propulsion technology scientists of the German Aerospace Centre (DLR, Cologne, Federal Republic of Germany) together with Rolls-Royce have built a combustion chamber test section. Using cameras and laser technology they observe and analyse the lean combustion exactly.

In diedaaropvolgende oorlog het die republieke in die eerste maande heldhaftig hul grense verdedig totdat lord Roberts met 'n sterk troepemag daaringeslaag het om die Boeremagte te ontsetel uit 'hulle stellings en gaandeweg daarin geslaag het om vanuit die Kaapkolonie noordwaarts op te ruk deur die Vrystaat.

Awareness of the loss, confrontation and adaption are the main phases of the mourning process, although each mourner’s reactions are highly individulised. Mourning can be regarded as essential “work” — which can never be escaped. The bond with the deceased must be untied, the mourner must adapt to the new environment without the loved one and then form new relationships. In offering support to mourners one should be there, allow them to express their emotions in their own way and to talk about the deceased and their feelings of guilt. One should also lead them to understand that their reaction is normal and that the work of mourning must be completed. After considerable time sensitive attempts may be made to direct the mourner to the future.

This study aimed at developing a new psychometrically sound instrument, the Managerial Motivation Questionnaire (MMQ. This was done on the basis of a comprehensive study of the literature on managerial motivation and the role-motivation theory. The preliminary MMQ was systematically shortened and refined until the final MMQ of 98 items was composed. This was based on social desirability and semantic appraisal, item analysis and factor analysis of the questionnaire. The results indicate that it was possible to develop a final MMQ that was relatively free of social desirability. It further demonstrated satsifactory internal consistencies on two samples (a = 0/90, N = 360; a = 0/91, N = 535, where all subscale items were found to be relatively pure measures of the isolated factors. Although some evidence was found providing support for the reliability of the MMQ, a need for further research on the construct validity of managerial motivation still exists. Opsomming In die literatuur word verskeie punte van kritiek teen die psigometriese geskiktheid van bestaande meetinstrumente van bestuursmotivering gerapporteer.

    The delivery of psychiatric care is changing with a new emphasis on integrated care, preventative measures, population health, and the biological basis of disease. Fundamental to this transformation are big data and advances in the ability to analyze these data. The impact of big data on the routine treatment of bipolar disorder today and in the near future is discussed, with examples that relate to health policy, the discovery of new associations, and the study of rare events. The primary sources of big data today are electronic medical records (EMR), claims, and registry data from providers and payers. In the near future, data created by patients from active monitoring, passive monitoring of Internet and smartphone activities, and from sensors may be integrated with the EMR. Diverse data sources from outside of medicine, such as government financial data, will be linked for research. Over the long term, genetic and imaging data will be integrated with the EMR, and there will be more emphasis on predictive models. Many technical challenges remain when analyzing big data that relates to size, heterogeneity, complexity, and unstructured text data in the EMR. Human judgement and subject matter expertise are critical parts of big data analysis, and the active participation of psychiatrists is needed throughout the analytical process.

Dieser Beitrag beleuchtet kritisch das Zusam­menspiel von Discovery Systemen und Informationskompetenz anhand von Recherchegewohnheiten eher untrainierter Studierender. Anhand einer kurzen Gegenüberstellung der unterschiedlichen Recherche­konzepte von Suchmaschinen und bibliothekarischen Rechercheangeboten werden Rückschlüsse auf die zu fördernden Schwerpunkte bei der Informationskompetenz gezogen und untersucht, welche Schlüsselrolle Discovery Systeme dabei spielen.The dissemination of discovery systems has raised hopes that the need for extensive teaching of information literacy might be reduced in the future. Also, their intuitive approach has been hopefully seen to enable the development of a better information literacy. This article critically focusses on the interaction of discovery systems and information literacy by analysing research behaviours of comparatively untrained students. In order to define which specific themes should be promoted by information literacy education, the author examines various research concepts of search engines as well as research offers of libraries. On this basis the key role of discovery systems will be explored.

  1. Renewable Energy Law or quota? Market integration of renewable energies in the future; EEG oder Quote? Die Zukunft der Marktintegration erneuerbarer Energien

    Bertram, Franz [Internationales Wirtschaftsforum Regenerative Energien (IWR), Muenster (Germany)

    2013-05-15

    The expansion of renewable energies figures at the centre of the energy policy debate in Germany. On the one hand this has been a success story over the past years, as is reflected by corresponding increases in electricity production and a marked increase in the capacity of renewable energy production. On the hand the development of the reallocation charge under the Renewable Energy Law (EEG), along with other challenges associated with the energy turnaround such as the expansion of the networks, have evoked fundamental criticism against the EEG. This provokes the question as to whether feed-in rates or quotas are the better means of achieving the set expansion goals for renewable energies. A fundamental analysis of the systems used within the EU for managing renewable energies shows that the majority of member states rely on feed-in models and that they fare better in terms of achieving their goals than do countries with quota models. For Germany's future it would therefore appear advisable to expand the existing EEG system by addressing the demand side and to give it a significantly more efficient design.

    In the Federal Republic of Germany, the legislator introduced a fixed price system for the attainment of the goals of the renewable energy law. It is questionable whether the German fixed price model in a liberalized energy market can continue legally. The renewable energy law also is disputed constitutionally. Under this aspect, the author of the contribution under consideration reports on the future compatibility of the renewable energy law with the constitutional law and European law. First of all, the actual development of the feed-in law in the German electricity market is described. Subsequently, the development from the current feed-in law to the renewable energy law in the Federal Republic of Germany is presented. It is examined whether the renewable energy law offends against the financial constitutional law. The central point of the question is whether the addressees of the law are illegally injured in its fundamental rights from Sect. 12 GG and Sect. 14 GG. In the background the community-legal basic conditions, the compatibility of the renewable energy law with Community law recently is to be examined.

  3. Why Do So Many Calves Die on Modern Dairy Farms and What Can We Do about Calf Welfare in the Future?

    Directory of Open Access Journals (Sweden)

    John F. Mee

    2013-11-01

    Full Text Available Poor bovine neonatal survival rates are an international animal welfare issue. The key modifiable risk factors associated with such loss are age at first calving in primiparae, calf breed, gender and gestation length and calving management. The primary causes of mortality in the perinatal period are calving problems, in particular dystocia, defined as both difficult and abnormal calvings. Calf loss rates are rising on modern dairy farms in many countries internationally. High calf loss rates are often not recognised at national or at farm-level; recording needs to be improved. Improving bovine neonatal survival requires re-prioritization of this issue. Stakeholders need to be made cognisant of this prioritization. Actions to effect change need to occur at both national and farm-levels. National-level actions need firstly to address raising awareness of the issue. Farm-level actions need to focus on identifiable problem farms through targeted surveillance. Application of existing knowledge to alter modifiable risk factors is the key to improving calf welfare in the future. Research also has a role to play in filling knowledge gaps in particular about the ‘unexplained stillbirth’.

    A heater for heating packaged die for burn-in and heat testing is described. The heater may be a ceramic-type heater with a metal filament. The heater may be incorporated into the integrated circuit package as an additional ceramic layer of the package, or may be an external heater placed in contact with the package to heat the die. Many different types of integrated circuit packages may be accommodated. The method provides increased energy efficiency for heating the die while reducing temperature stresses on testing equipment. The method allows the use of multiple heaters to heat die to different temperatures. Faulty die may be heated to weaken die attach material to facilitate removal of the die. The heater filament or a separate temperature thermistor located in the package may be used to accurately measure die temperature.

    part of the debate. Also in dispute, was the location of the Academy at Saldanha, rather than in the military heart-land in Pretoria. By interpreting the academic training needs of the Defence Force correctly and positioning itself accordingly, the Academy survived that crisis. Thereafter, the Academy time and again adapted to the changing military and socio-political environment and strove towards ever increasing relevance to the Defence Force. In this way female and non-European students were admitted to the Military Academy, whilst the way was also paved for the admittance of students from other African states. In anticipation of the new political dispensation in South Africa, a concerted effort was launched in 1990 to make the student body more representative of the South Africa population in terms of race and sex. The Military Academy has through the years established itself as a credible military academic institution and has made a significant contribution towards military professionalism in South Africa. By 1990 it favourably positioned itself to continue that role in future. Though forming only a small percentage of the total officer corps, the Academy graduates have gradually been distributed at all levels of the' officer corps and have dominated the top posts in the SA Defence Force since the early 1970's. They were consequently well placed in 1990 to play a significant role in preparing the Defence Force for the so-called "New South Africa". ****** AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse Militêre Akademie is op 1 April 1950 gestig met die doel om die militêrakademiese opleiding van kandidaatoffisiere hier te lande op dieselfde peil as in die buiteland te bring en dit terselfdertyd tot universiteitsvlak te verhef. Die Minister van Verdediging, F.C.

In die eerste metode word die bepaling deur middel van oplossingsviskometrie gedoen, maar die toksisiteit van die oplosmiddel, asook die tydperk wat dit neem om die bepaling te doen, is ’n probleem. Die tweede metode word beperk deur die kompleksiteit en beskikbaarheid van die apparatuur in Suid-Afrika. In hierdie studie word ’n alternatiewe metode, gebaseer op parallelplaatreologie, voorgestel wat albei hierdie probleme oorkom en die resultate sodoende verkry, word vergelyk met dié wat met bestaande metodes verkry is.

    Full Text Available Genomics is a Big Data science and is going to get much bigger, very soon, but it is not known whether the needs of genomics will exceed other Big Data domains. Projecting to the year 2025, we compared genomics with three other major generators of Big Data: astronomy, YouTube, and Twitter. Our estimates show that genomics is a "four-headed beast"--it is either on par with or the most demanding of the domains analyzed here in terms of data acquisition, storage, distribution, and analysis. We discuss aspects of new technologies that will need to be developed to rise up and meet the computational challenges that genomics poses for the near future. Now is the time for concerted, community-wide planning for the "genomical" challenges of the next decade.

    2015-08-01

    The concept of "big data" stands to change the face of official statistics over the coming years, having an impact on almost all aspects of data production. The tasks of future statisticians will not necessarily be to produce new data, but rather to identify and make use of existing data to adequately describe social and economic phenomena. Until big data can be used correctly in official statistics, a lot of questions need to be answered and problems solved: the quality of data, data protection, privacy, and the sustainable availability are some of the more pressing issues to be addressed. The essential skills of official statisticians will undoubtedly change, and this implies a number of challenges to be faced by statistical education systems, in universities, and inside the statistical offices. The national statistical offices of the European Union have concluded a concrete strategy for exploring the possibilities of big data for official statistics, by means of the Big Data Roadmap and Action Plan 1.0. This is an important first step and will have a significant influence on implementing the concept of big data inside the statistical offices of Germany. PMID:26077871

Dabei kommt er zu der Schlussfolgerung, dass sich die Verse der Satire durch eine gute Technik auszeich­ nen, dass aber auch eine unnötige Weitschweifigkeit nicht zu Ubersehen ist. Trotzdem kann man jedoch dem Dichter nicht die künstlerische Überzeugungskraft absprechen, wie auch die Ten­ denz nach Detailschilderungen und die Feinheit geistreicher Charakterisierungen. Die Aussage beinhaltet manchmal eine be­ stimmte innere Ironie in der Einfachheit der Wörter.In kurzen Fragmenten wird die Fähigkeit des Semonides sichtbar, sich sehr präzise auszudrücken. Seine ironisch-epische Sprache ist sehr reich  und verdient vom linguistischen Standpunkt aus Auf­ merksamkeit wegen ihres reichhaltigen lexischen und termino­ logischen Materials, insbesondere was die Bereiche der Tier­ welt und des Essens anbelangt.Die Weltanschauung des Dichters ist in dem ersten Fragment recht deutlich erkennbar.

U moet my vergun om met u te spreek oor een so ’n modewoord nl „verskuiwing’’ in die moraal. Dis nogal ’n mooi woord, wat so dikwels gebruik word op baie terreine en tog meer wil aandui as maar net ’n veranderde sienswyse, ’n wysiging in opvattinge of nuwe riglyne wat al gangbaar geword het in die praktyk. Die begrip wil eintlik die ewolusionêre gang beklemtoon, want dit is dan eintlik net die ou norme wat effens anders bekyk word of nie meer so nou geneem of dik onderstreep word nie. Die verskuiwing beteken dan dat alles nog dieselfde bly, net die posisie of plek het verander. Verskuiwing beteken tog plekverandering of plekwisseling en dan sekerlik nie in die sin dat die plekke ver uitmekaar lê nie. Verskuiwing beteken net maar vlak langs die vorige te staan kom. As dit dan ’n beter plek is, is dit ewolusie, ontwikkeling, verbetering.

Met verwysing na die staat is dan gespreek van die staatstaak as synde die hand- hawing van die reg, en omdat die staat in toenemende mate hom veral in die latere tyd ook besig gehou het met bedrywig- hede wat nouliks as van juridiese aard beskou kan word, is daar die onderskeid gemaak tussen die primêre en sekundêre taak van die staat. Die sistematiek van die wetsidee, deur prof. Dooyeweerd ontwikkel, waar die staat sy bestemmingsfunksie in die regsaspek vind, het vanselfsprekend geen plek vir so 'n dualistiese staatstaak nie, en die oplossing is deur sommige daarin gesoek om sulke staatsoptrede te vertolk as hebbende wel betrekking op die regsgemeenskap of die regsverkeer. Staatsondernemings soos paaie, spoorweë, spellingreëling, ens. word dan beskou as noodsaaklik vir die instandhouding van die regsgemeenskap en regsverkeer. Tereg wys A. M. Donner1 daarop dat so ’n vertolking eintlik neerkom op ’n oorspanning van die regsbegrip. Hy self sien dan die staatstaak in vrede- of orde-handhawing, wat in die eerste plaas wel regshandha- wing veronderstel. Onder orde word dan alles verstaan wat noodsaaklik is vir die gladde verkeer in die ontwikkelingsgang van die regsgemeenskap. Die wese van die staat het dan vol- gens hom te doen met reg, maar sy taak is meer as suiwere regshandhawing. Wat onrus verwek en die orde versteur, moet uit die openbare lewe verwyder word, en die

  3. Die singulation method

    A method is disclosed for singulating die from a semiconductor substrate (e.g. a semiconductor-on-insulator substrate or a bulk silicon substrate) containing an oxide layer (e.g. silicon dioxide or a silicate glass) and one or more semiconductor layers (e.g. monocrystalline or polycrystalline silicon) located above the oxide layer. The method etches trenches through the substrate and through each semiconductor layer about the die being singulated, with the trenches being offset from each other around at least a part of the die so that the oxide layer between the trenches holds the substrate and die together. The trenches can be anisotropically etched using a Deep Reactive Ion Etching (DRIE) process. After the trenches are etched, the oxide layer between the trenches can be etched away with an HF etchant to singulate the die. A release fixture can be located near one side of the substrate to receive the singulated die.

    Full Text Available In Ou Egipte is mummifikasie met uitgebreide reseksie of uitsnyding van organe geassosieer, maar geen kennis is geneem van die morfologie van die brein nie. Griekse skrywers van die sesde en vyfde eeue v.C. het die brein aanvanklik gesien as die setel van intelligensie, die orgaan van sensoriese waarneming en gedeeltelik die oorsprong van sperma. Pneuma het ’n belangrike rol in breinfunksie gespeel. Hippokrates was die eerste om die brein te beskryf as ’n dubbele orgaan, wat met harsingvlies (meninges bedek, funksioneel van pneuma afhanklik en vertolker van begrip is. Tydgenote soos Plato, Aristoteles en Diokles het tot die beskrywing bygedra, maar laasgenoemde twee het beweer dat die hart die middelpunt van intelligensie is en nie die brein nie. Gedurende die laaste helfte van die vierde eeu v.C. is disseksie van die menslike liggaam tydelik aan die mediese skool van Alexandrië toegelaat en het dit tot merkwaardige vooruitgang in die begrip van die menslike anatomie en fisiologie gelei. Herofilus en Erasistratus het uitstekende beskrywings van die struktuur en funksie van die brein gegee wat eers in die tweede eeu n.C. deur Galenus geëwenaar is.

The wormhole is modeled by a thin spherical shell accreting the superquintessence fluid - two different models are presented. Contrary to recent claims that the wormhole overtakes the expansion of the universe and engulfs it before the Big Rip is reached, it is found that the wormhole becomes asymptotically comoving with the cosmic fluid and the future evolution of the universe is fully causal.

    We consider conditions under which a universe contracting towards a big crunch can make a transition to an expanding big bang universe. A promising example is 11-dimensional M-theory in which the eleventh dimension collapses, bounces, and re-expands. At the bounce, the model can reduce to a weakly coupled heterotic string theory and, we conjecture, it may be possible to follow the transition from contraction to expansion.

Wenn wir diese zwei Visionen für das zukünftige Web unter die Lupe nehmen, dann lässt sich feststellen, dass sich die Ideen in ihrem Kern und ihren Technologien gegenseitig ergänzen. Dementsprechend können und sollen beide Visionen von den Erfahrungen und Stärken der anderen profitieren. Wir glauben daran, dass zukünftige Webanwendungen den Web 2.0-Fokus auf Community und Benutzerfreundlichkeit beibehalten und, darüber hinaus, auch von Technologien des Semantic Web zur Vereinfachung der mashupähnlichen Datenintegration profitieren werden. Auf Basis eines Semantic Blog-Szenarios werden wir hier die Vorteile einer möglichen Kombination von Semantic Web und Web 2.0 illustrieren, die zeitnah realisiert werden kann. Wir werden auch auf technische Probleme eingehen, die bei der Erweiterung dieses Szenarios entstehen. Wir stellen dar, wie aktuelle Entwicklungen in der Semantic Web Forschung diese Probleme angehen können, und setzen zugleich auch Schwerpunkte für die zukünftige Forschung, die in diesem Zusammenhang relevant sind.

  15. The little wave with the big future

    Energy Technology Data Exchange (ETDEWEB)

    Addison, Paul [CardioDigital Ltd, Edinburgh (United Kingdom)

    2004-03-01

    By extracting information from noisy, aperiodic and intermittent signals, wavelet transforms are making an impact in medicine, astronomy, imaging and beyond. A few years ago we were studying the signals from a medical device called a pulse oximeter. Widely used in hospitals to measure the percentage of blood haemoglobin that is saturated with oxygen, the device also provides an accurate measure of a patient's heart rate. We had been trying to use the oximeter to measure how ill patients were, based on subtle changes to these signals, which repeat regularly once every heartbeat. Using the relatively new technique of 'wavelet transforms', we suddenly realized that some of the regular patterns that were appearing in our signal were not caused by the beating heart. They were, in fact, caused by the patient's breathing. Moreover, the breathing signals were much clearer than could be measured using traditional methods. We have since used this technique to study the breathing patterns of newborn babies. This finding is one example of the many ways in which data can be analysed using wavelet transforms. The technique is ideal for teasing out information from signals that are aperiodic, noisy, intermittent or transient. It has been used by many different researchers to study climate patterns and financial indices, to monitor heartbeats and rotating machinery, to de-noise seismic signals and astronomical images, to characterize cracks and turbulence, and to compress electronic and medical images. Many of the ideas behind wavelet transforms have been around for a long time. Indeed, the first 'wavelet' - a simple, square waveform - was developed by the mathematician Alfred Haar at the beginning of the last century. But it was not until the mid-1980s that true wavelet-transform analysis was developed by Jean Morlet and Alex Grossmann. Morlet,who was an engineer with the French oil firm Elf Aquitane, developed the technique to study seismic signals. He then teamed up with Grossmann, who worked at the CNRS Centre for Theoretical Physics in Marseille, to formalize the mathematics of the wavelet transform. Despite their efforts, wavelet analysis initially remained confined to a small, mainly mathematical, community with only a handful of scientific papers being published each year. At the end of the 1980s, however, two further important mathematical advances were made by Ingrid Daubechies at the Courant Institute in New York and by Stephane Mallat at the University of Pennsylvania. By the start of the 1990s the stage was set for the practical application of wavelet analysis in science and engineering - and more and more researchers spotted the potential of the technique.

    Full Text Available The world has been drowned by floods of data due to technological development. Consequently, the Big Data term has gotten the expression to portray the gigantic sum. Different sorts of quick data are doubling every second. We have to profit from this enormous surge of data to convert it to knowledge. Knowledge Discovery (KDD can enhance detecting the value of Big Data based on some techniques and technologies like Hadoop, MapReduce, and NoSQL. The use of Big Data value is critical in different fields. This survey discusses the expansion of data that led the world to Big Data expression. Big Data has distinctive characteristics as volume, variety, velocity, value, veracity, variability, viscosity, virality, ambiguity, and complexity. We will describe the connection between Big Data and KDD techniques to reach data value. Big Data applications that are applied by big organizations will be discussed. Characteristics of big data will be introduced, which represent a significant challenge for Big Data management. Finally, some of the important future directions in Big Data field will be presented.

Marcant and sometimes little known examples show the different functions of intabulations: repertoire for the organists (liturgical function, music of delight and pedagogical functions. As a part of Ars Organistum intabulations were the basis of professional musical studies, learning to improvise organ music and to compose music. Masters like H. Scheidemann, the both Gabrielis, J. de Lublin, P. Philips, the both Cabezóns, some English and French anonym composers demonstrate that intabulations are much more than keyboard reductions - artful arrangements with their own life and character on the way to artful paraphrases. The intentions of the composers / arrangers in connection with the possibilities of the keyboard instruments definite the character and the step of transforming a vocal set in a (new piece of keyboard music.

    Full Text Available The prospect of “big data” at once evokes optimistic views of an information-rich future and concerns about surveillance that adversely impacts our personal and private lives. This overview article explores the implications of big data in education, focusing by way of example on data generated by student writing. We have chosen writing because it presents particular complexities, highlighting the range of processes for collecting and interpreting evidence of learning in the era of computer-mediated instruction and assessment as well as the challenges. Writing is significant not only because it is central to the core subject area of literacy; it is also an ideal medium for the representation of deep disciplinary knowledge across a number of subject areas. After defining what big data entails in education, we map emerging sources of evidence of learning that separately and together have the potential to generate unprecedented amounts of data: machine assessments, structured data embedded in learning, and unstructured data collected incidental to learning activity. Our case is that these emerging sources of evidence of learning have significant implications for the traditional relationships between assessment and instruction. Moreover, for educational researchers, these data are in some senses quite different from traditional evidentiary sources, and this raises a number of methodological questions. The final part of the article discusses implications for practice in an emerging field of education data science, including publication of data, data standards, and research ethics.

    Full Text Available Nooit sou die Franse jeug — en die van Europa en verder — in dié mate deur die eksistensialisme be'invloed gewees het nie, indien hierdie filosofie in wysgerige traktate sou begrawe gelê het. Die eksistensialiste het die koning van die filosofiese verhaal, Voltaire, met sukses op sy Candide- en Zadig-pad gevolg en hulle teorieë in letterkundige werke, ver- hale, romans en ook toneelstukke kwytgeraak, wat baie gelees is en waaruit ook ander literatore kragte en inspirasie geput het. Omrede daarvan is daar inderdaad baie eksistensialisme in die Franse letterkunde, maar ’n eintlike eksistensialistiese letterkunde was daar nie, en ’n Eksistensialistiese Letterkun­ dige skool het nooit bestaan nie. Ook sit hierdie eksistensialiste nie langs dieselfde vuur nie. Die Christelike eksistensialis Gabriel Marcel het op 21 April van hierdie jaar uitgevaar teen die „Sartriane” na aanleiding van die opvoering van Les Paravents, Die W indskerms van Jean Genêt in ’n Paryse staatsondersteunde teater. „Mens mag seker wees”, skryf Marcel in Les Nouvelles Littéraires, „dat die hele sartriaanse parogie sal skreeu: groot meesterwerk”. Voortgaande op sy distansiëring kan die literêre eksistensialiste in drie groepe ingedeel word: 1. Die Sartriane; 2. Die Christelike Eksistensialiste; 3. Die Onafhanklikes.

    1976-11-01

    Full Text Available Ergonomics (a synonym for human factors engineering has contributed significantly to fundamental effectiveness of people, but needs a new emphasis and wider applications in future. A basic distinction is drawn between the areas of application and the focus of ergonomists. Although applications have been relatively successful in the military and industrial fields, ergonomics should also be applied to consumer products, architecture, transportation and recreation. In future, the primary challenge will be to improve the "quality of life" by enhancing human satisfaction and allowing people to function at higher value levels. In work activities the basic task of ergonomics has been to simplify and standardise jobs, but future focus should be on enlargement and enrichment of jobs. Because of individual differences probably not all jobs could be made completely satisfactory to all workers. However, significant contributions could be made through continued efforts to “humanise” work activities.Opsomming Ergonomika ('n sinoniem vir "human factors engineering" het reeds heelwat bygedra tot die doeltreffende funksionering van die mens, maar nuwe gesigspunte en toepassingsvelde sal in die toekoms nodig wees. 'n Fundamentele onderskeid word getref tussen die gebiede van toepassing en die fokus van beoefenaars van die ergonomika. Hoewel toepassings in die militêre en industriële sfere redelik suksesvol was, behoort ergonomiese beginsels ook op verbruikerswese, argitektuur, vervoer en ontspanning toegepas te word. Die grootste uitdaging in die toekoms sal egter wees om "lewenskwaliteit" te verbeter deur tevredenheid te verhoog en mense te help om doeltreffender te leef en in die proses hoër waardevlakke te handhaaf. In werksaktiwiteite was die hoofdoel tot dusver om werk te standaardiseer en te vereenvoudig, maar dit word al hoe noodsaakliker dat poste verruim en verryk moet word. Waarskynlik sal alle poste nie vir alle bekleërs volkome bevredigend

    International Nuclear Information System (INIS)

    Business to business electronic commerce is looming large in the future of the oil industry. It is estimated that by adopting e-commerce the industry could achieve bottom line savings of between $1.8 to $ 3.4 billion a year on annual gross revenues in excess of $ 30 billion. At present there are several teething problems to overcome such as inter-operability standards, which are at least two or three years away. Tying in electronically with specific suppliers is also an expensive proposition, although the big benefits are in fact in doing business with the same suppliers on a continuing basis. Despite these problems, 14 of the world's largest energy and petrochemical companies joined forces in mid-April to create a single Internet procurement marketplace for the industry's complex supply chain. The exchange was designed by B2B (business-to-business) software provider, Commerce One Inc., ; it will leverage the buying clout of these industry giants (BP Amoco, Royal Dutch Shell Group, Conoco, Occidental Petroleum, Phillips Petroleum, Unocal Corporation and Statoil among them), currently about $ 125 billion on procurement per year; they hope to save between 5 to 30 per cent depending on the product and the region involved. Other similar schemes such as Chevron and partners' Petrocosm Marketplace, Network Oil, a Houston-based Internet portal aimed at smaller petroleum companies, are also doing business in the $ 10 billion per annum range. e-Energy, a cooperative project between IBM Ericson and Telus Advertising is another neutral, virtual marketplace targeted at the oil and gas sector. PetroTRAX, a Calgary-based website plans to take online procurement and auction sales a big step forward by establishing a portal to handle any oil company's asset management needs. There are also a number of websites targeting specific needs: IndigoPool.com (acquisitions and divestitures) and WellBid.com (products related to upstream oil and gas operators) are just two examples.

Currently, over 2 billion people worldwide are connected to the Internet, and over 5 billion individuals own mobile phones. By 2020, 50 billion devices are expected to be connected to the Internet. At this point, predicted data production will be 44 times greater than that in 2009. As information is transferred and shared at light speed on optic fiber and wireless networks, the volume of data and the speed of market growth increase. However, the fast growth rate of such large data generates numerous challenges, such as the rapid growth of data, transfer speed, diverse data, and security. Nonetheless, Big Data is still in its infancy stage, and the domain has not been reviewed in general. Hence, this study comprehensively surveys and classifies the various attributes of Big Data, including its nature, definitions, rapid growth rate, volume, management, analysis, and security.

    Full Text Available Während der systolische Blutdruck in der Bevölkerung mit zunehmendem Lebensalter in jedem Dezennium weiter ansteigt, beginnt der diastolische Blutdruck ab dem 50. Lebensjahr für jede systolische Blutdruckstratifizierung als Ausdruck einer zunehmenden Gefäßschädigung wieder zu sinken. Deswegen muß der Blutdruck ausschließlich nach dem systolischen Blutdruck klassifiziert werden. Die Häufigkeitsverteilung des systolischen und diastolischen Blutdrucks innerhalb der Bevölkerung entspricht einer Gauss'schen Glockenkurve. Jede Unterteilung in normotensiv und hypertensiv entspricht deshalb einer völlig willkürlichen Dichotomisierung. Je niedriger der Blutdruck, desto geringer die mechanische Belastung der Blutgefäße und desto geringer auch die mechanisch induzierten Gefäßschäden. Das war der Grund für die zuletzt vom "7th JNC on Prevention, Detection and Treatment of Hypertension" des NIH, USA, vorgenommene Klassifizierung des Blutdrucks in normal (kleiner als 120 mmHg systolisch, prähypertensiv (120-140 mmHg und Hypertonie-Stadium I (140-160 mmHg systolisch und Hypertonie-Stadium II ( 160 mmHg systolisch. Damit muß leider die nahezu gesamte gesunde österreichische Bevölkerung, die nach bisheriger Klassifikation noch keinen Hochdruck aufweist, als prähypertensiv klassifiziert werden. Ein wirklicher Informationsgewinn (der ja mit der Klassifikation bezweckt wird ist meiner Meinung nach damit nicht mehr gegeben. Die Österreichische Hochdruckliga schlägt eine zusätzliche Klassifikation des Blutdrucks nach dem „Pressure Load“ vor, welches aus einer statistisch aussagekräftigen Zahl von Selbstmessungen leicht zu errechnen ist. Jedes Pressure Load von mehr als 20 % (mehr als 20 % der selbst gemessenen Blutdruckwerte 135/85 mmHg entspricht einer Hypertonie, die je nach Höhe der Blutdruckwerte entweder mit Änderungen des Lebensstils oder mit antihypertensiver Medikation zu bekämpfen ist.

    Energy consumption has decreased by 4.7 percent compared to the year 2013 in the year, 2014. The relatively mild weather of 2014 was significant responsible. The energy consumption reached 13,132 petajoules the lowest level since 1990. The renewable energies are Germany's most important power source. The share of renewable energy in electricity consumption in the first half 2015 was for the first time more than 30 percent. In the expansion of renewable energies in the electricity sector, Germany is on target. The amount of the EEG surcharge has stabilized. The average increase of the energy efficiency 2008-2014 was 1.6 percent lower than envisaged in the energy concept of the federal government of 2.1 percent. Here additional action is needed. The Federal Government has therefore bundled and enforced with the National Energy Efficiency Action Plan decided on December 3, 2014 to increase and to sthrengthend efficiency. Final energy consumption in transport was in 2014 approximately 1.7 percent higher than in 2005. In order to achieve the objective of reducing the final energy consumption by 10 percent compared to 2005, further efforts are needed. For the first time for over ten years electricity prices decreased at the beginning of 2015, for household customers. For industrial and commercial customers, which are not covered by an asset relief scheme, electricity prices in 2014 remained almost unchanged. The spot price of electricity is 2014 declined by 10 per cent and continued to decline in 2015. In 2014, Germany imported fossil fuels worth around 81 billion euros. In 2013 there were still 95 billion euros. The decline in import expenditure mainly due to lower raw material prices, but lower import volumes have also contributed.

    2015-01-01

    This book is a collection of chapters written by experts on various aspects of big data. The book aims to explain what big data is and how it is stored and used. The book starts from  the fundamentals and builds up from there. It is intended to serve as a review of the state-of-the-practice in the field of big data handling. The traditional framework of relational databases can no longer provide appropriate solutions for handling big data and making it available and useful to users scattered around the globe. The study of big data covers a wide range of issues including management of heterogeneous data, big data frameworks, change management, finding patterns in data usage and evolution, data as a service, service-generated data, service management, privacy and security. All of these aspects are touched upon in this book. It also discusses big data applications in different domains. The book will prove useful to students, researchers, and practicing database and networking engineers.

    The amount of data at the global level has grown exponentially. Along with this phenomena, we have a need for a new unit of measure like exabyte, zettabyte, and yottabyte as the last unit measures the amount of data. The growth of data gives a situation where the classic systems for the collection, storage, processing, and visualization of data losing the battle with a large amount, speed, and variety of data that is generated continuously. Many of data that is created by the Internet of Things, IoT (cameras, satellites, cars, GPS navigation, etc.). It is our challenge to come up with new technologies and tools for the management and exploitation of these large amounts of data. Big Data is a hot topic in recent years in IT circles. However, Big Data is recognized in the business world, and increasingly in the public administration. This paper proposes an ontology of big data analytics and examines how to enhance business intelligence through big data analytics as a service by presenting a big data analytics services-oriented architecture. This paper also discusses the interrelationship between business intelligence and big data analytics. The proposed approach in this paper might facilitate the research and development of business analytics, big data analytics, and business intelligence as well as intelligent agents.

    Future large radio astronomy arrays, particularly the Square Kilometre Array (SKA), will be able to generate data at rates far higher than can be analyzed or stored affordably with current practices. This is, by definition, a "big data" problem, and requires an end-to-end solution if future radio arrays are to reach their full scientific potential. Similar data processing, transport, storage, and management challenges face next-generation facilities in many other fields.

    Full Text Available A field and Laboratory study were conducted to determine the relationship between Leadership style, time-span of discretion and group performance. The results of this research support the prediction that situational variables such as time-span of discretion tend to moderate the relationship between Leadership style and group performance. Implications for future theory development, research and applications are discussed. Opsomming In 'n gekontroleerde laboratorium- en kontrolestudie is die verband tussen leierskapstyl en bestuursdoeltreffendheid onder verskillende tydspantoestande bepaal. Resultate toon aan dat beide leierskapstyl en tydspan 'n invloed uitoefen op bestuursdoeltreffendheid. Doeltreffendheid kan beskou word as 'n funksie van die aanpassing van basiese leierskapstyl by die betrokke situasie. Die gevolge wat hierdie bevindings vir verdere navorsing en bestuursontwikkeling mag inhou, word bespreek.

    High-speed injection die casting is an efficient manufacturing technology for upgrading aluminum die-cast products. However, deficiencies (such as die damage in eady period) due to larger load on the molding die compared with conventional technology have brought new challenges. In this study, the cause of damage generated in super high-speed injection was investigated by the combination of experimental observation of the dies and CAE simulation (e.g. die temperature analysis, flow analysis and thermal stress analysis). The potential countermeasures to solve the above problems were also proposed.

We are moving towards changes in how ethics has to be perceived: away from individual decisions with specific and knowable outcomes, towards actions by many unaware that they may have taken actions with unintended consequences for anyone. Responses will require a rethinking of ethical choices, the lack thereof and how this will guide scientists, governments, and corporate agencies in handling Big Data. This essay elaborates on the ways Big Data impacts on ethical conceptions.

    Full Text Available Research on so-called ‘Big Data’ has received a considerable momentum and is expected to grow in the future. One very interesting stream of research on Big Data analyzes online networks. Many online networks are known to have some typical macro-characteristics, such as ‘small world’ properties. Much less is known about underlying micro-processes leading to these properties. The models used by Big Data researchers usually are inspired by mathematical ease of exposition. We propose to follow in addition a different strategy that leads to knowledge about micro-processes that match with actual online behavior. This knowledge can then be used for the selection of mathematically-tractable models of online network formation and evolution. Insight from social and behavioral research is needed for pursuing this strategy of knowledge generation about micro-processes. Accordingly, our proposal points to a unique role that social scientists could play in Big Data research. ...

  1. Navigating "Assisted Dying".

    Science.gov (United States)

    Schipper, Harvey

    2016-02-01

    Carter is a bellwether decision, an adjudication on a narrow point of law whose implications are vast across society, and whose impact may not be realized for years. Coupled with Quebec's Act Respecting End-of-life Care it has sharply changed the legal landscape with respect to actively ending a person's life. "Medically assisted dying" will be permitted under circumstances, and through processes, which have yet to be operationally defined. This decision carries with it moral assumptions, which mean that it will be difficult to reach a unifying consensus. For some, the decision and Act reflect a modern acknowledgement of individual autonomy. For others, allowing such acts is morally unspeakable. Having opened the Pandora's Box, the question becomes one of navigating a tolerable societal path. I believe it is possible to achieve a workable solution based on the core principle that "medically assisted dying" should be a very rarely employed last option, subject to transparent ongoing review, specifically as to why it was deemed necessary. My analysis is based on 1. The societal conditions in which have fostered demand for "assisted dying", 2. Actions in other jurisdictions, 3. Carter and Quebec Bill 52, 4. Political considerations, 5. Current medical practice. Leading to a series of recommendations regarding. 1. Legislation and regulation, 2. The role of professional regulatory agencies, 3. Medical professions education and practice, 4. Public education, 5. Health care delivery and palliative care. Given the burden of public opinion, and the legal steps already taken, a process for assisted-dying is required. However, those legal and regulatory steps should only be considered a necessary and defensive first step in a two stage process. The larger goal, the second step, is to drive the improvement of care, and thus minimize assisted-dying. PMID:27169205

  7. The Big Bang Singularity

    Science.gov (United States)

    Ling, Eric

    The big bang theory is a model of the universe which makes the striking prediction that the universe began a finite amount of time in the past at the so called "Big Bang singularity." We explore the physical and mathematical justification of this surprising result. After laying down the framework of the universe as a spacetime manifold, we combine physical observations with global symmetrical assumptions to deduce the FRW cosmological models which predict a big bang singularity. Next we prove a couple theorems due to Stephen Hawking which show that the big bang singularity exists even if one removes the global symmetrical assumptions. Lastly, we investigate the conditions one needs to impose on a spacetime if one wishes to avoid a singularity. The ideas and concepts used here to study spacetimes are similar to those used to study Riemannian manifolds, therefore we compare and contrast the two geometries throughout.

It is estimated that in 2015,8 Zettabytes (Zetta=1021) were generated which consistedmostly of unstructured data such as emails, blogs, Twitter,Facebook posts, images, and videos. This is called big data. Itis possible to analyse such huge data collections with clustersof thousands of inexpensive computers to discover patterns inthe data that have many applications. But analysing massiveamounts of data available in the Internet has the potential ofimpinging on our privacy. Inappropriate analysis of big datacan lead to misleading conclusions. In this article, we explainwhat is big data, how it is analysed, and give some case studiesillustrating the potentials and pitfalls of big data analytics.

    It is shown in this paper that minisuperspace quantization of homogeneous and isotropic geometries with phantom scalar fields, when examined in the light of the Bohm-de Broglie interpretation of quantum mechanics, does not eliminate, in general, the classical big rip singularity present in the classical model. For some values of the Hamilton-Jacobi separation constant present in a class of quantum state solutions of the Wheeler-DeWitt equation, the big rip can be either completely eliminated or may still constitute a future attractor for all expanding solutions. This is contrary to the conclusion presented in Ref.[1], using a different interpretation of the wave function, where the big rip singularity is completely eliminated ("smoothed out") through quantization, independently of such separation constant and for all members of the above mentioned class of solutions. This is an example of the very peculiar situation where different interpretations of the same quantum state of a system are predicting different...

    Full Text Available Die konsep, eunug, wat na ’n gekastreerde persoon (gewoonlik manlik verwys, het sy oorsprong in die mitologie. Van hier word dit deurgevolg na die Klassieke tydperk. Kastrering vir religieuse redes was deel van godsdiensrituele gekoppel aan verering van aardgodinne en fertiliteit. Die kultusse wat aan die godinne Kubele, Hekate, Atargatis-Dea, Astarte, Artemis en Innana-Ishtar gewy was en wat deur eunugpriesters bedien was, word beskryf. Kastrering vir niereligieuse redes, oorwegend weens sosio-ekonomiese oorwegings, het waarskynlik tydens die 2de millennium v.C. sy oorsprong in Midde-Oosterse lande gehad vanwaar dit teen ongeveer die 5de eeu v.C. na Griekeland, en twee eeue later na Rome uitgebrei het. ’n Oorsig word gelewer van die invloed en rol van die eunug ten tye van die klassieke beskawing. Die sogenaamde “kongenitale eunug” waar hipogonadisme weens ’n aangebore letsel ontstaan, ’n baie seldsame verskynsel, word nie verder bespreek nie.

    Big data introduces challenges to query answering, from theory to practice. A number of questions arise. What queries are “tractable” on big data? How can we make big data “small” so that it is feasible to find exact query answers? When exact answers are beyond reach in practice, what approximation theory can help us strike a balance between the quality of approximate query answers and the costs of computing such answers? To get sensible query answers in big data, what else do we necessarily do in addition to coping with the size of the data? This position paper aims to provide an overview of recent advances in the study of querying big data. We propose approaches to tackling these challenging issues, and identify open problems for future research.

    Technology leads discovery in astronomy, as in all other areas of science, so growth in technology leads to the continual stream of new discoveries which makes our field so fascinating. Derek de Solla Price had analysed the discovery process in science in the 1960s and he introduced the terms 'Little Science' and 'Big Science' as part of his discussion of the role of exponential growth in science. I will show how the development of astronomical facilities has followed this same trend from 'Little Science' to 'Big Science' as a field matures. We can see this in the discoveries resulting in Nobel Prizes in astronomy. A more detailed analysis of discoveries in radio astronomy shows the same effect. I include a digression to look at how science progresses, comparing the roles of prediction, serendipity, measurement and explanation. Finally I comment on the differences between the 'Big Science' culture in Physics and in Astronomy.

    Full Text Available Any peace process is an exercise in the negotiation of big data. From centuries old communal hagiography to the reams of official texts, media coverage and social media updates, peace negotiations generate data. Peacebuilding and peacekeeping today are informed by, often respond and contribute to big data. This is no easy task. As recently as a few years ago, before the term big data embraced the virtual on the web, what informed peace process design and implementation was in the physical domain – from contested borders and resources to background information in the form of text. The move from analogue, face-to-face negotiations to online, asynchronous, web-mediated negotiations – which can still include real world meetings – has profound implications for how peace is strengthened in fragile democracies.

    Full Text Available The ethics of futures markets Formal futures markets were introduced in South Africa during the beginning of the 1990s. The aim of this article is to investigate the perception that futures markets amount to gambling practices and that they should as such not be tolerated within an economy. Evidence exists of futures markets being banned in countries such as Germany and France because of the belief that these markets foster gambling. The truth in this regard, however, is that futures markets serve as an imperative for the hedging o f price risks by means of futures contracts. Price risks have always been an inherent part o f the free market economy and as such the management of this kind of risk has been making stiff demands on markets in the economy. The manifestation and rapid growth of futures markets in South Africa show that economic needs are thus satisfied. - An important distinction between futures markets and gambling concerns the benefits accruing to society as a whole. It is shown that major differences exist between futures markets and gambling. The proper functioning of a formal futures market is acceptable both on moral and ethical grounds, and thus is also compatible with a Christian philosophy of life.

The aim of the study was to establish the relationship between locus of control and the work performance of black marketers in the life assurance industry. These constructs were selected by virtue of the lack of empirical research regarding the assumed relationship between them. The Locus of Control Scale of Schepers (1995 was used for measuring locus of control. Work performance was measured by the commission earned per month by the marketer, the number of policies generated by the marketer, as well as the percentage of lapsed policies. The relevant measurements were obtained in respect of a sample of 149 black marketing personnel. The results indicated a modest but statistically significant relationship between external locus of control and the work performance of black marketers.

  9. Is die ortodoksie se verstaan van die sondeval belemmerend vir die gesprek tussen teologie en natuurwetenskap?

    Directory of Open Access Journals (Sweden)

    Johan Buitendag

    2012-09-01

    Full Text Available In hierdie artikel is betoog dat die Gereformeerde Ortodoksie se begrip van die sondeval ’n  belemmering  was  vir  die  gesprek  tussen  teologie  en  natuurwetenskap.  Die  rede hiervoor was dat dit ten eerste ’n bepaalde verstaan van liniêre tyd nahou en ten tweede dat dit ’n bonatuurlike ingryp veronderstel het. Albei hierdie aspekte het die debat onnodig problematiseer. Die argument is ontwikkel deur eerstens die probleem te definieer, gevolg deur ’n uiteensetting van die standpunte van Augustinus en Calvyn onderskeidelik oor die sondeval. As ’n heuristiese sleutel is die konsepte van infralapsarisme en supralapsarisme aangewend om die tema te ontleed. Die artikel is afgesluit met die oortuiging dat die imago Dei ’n beliggaamde menslike persoon is wat biologies in die geskiedenis in terme van selfbewussyn en morele verantwoordelikheid ontluik het.Is the Orthodoxy’s notion of the Fall inhibitory for the dialogue between theology and science? In this article it was argued that the Reformed Orthodoxy’s interpretation of the Fall had become an impediment in the dialogue between theology and science. The reason was that it assumed firstly a specific understanding of linear time and secondly a metaphysical intervention. Both events were unnecessarily problematising the debate. The argument was deployed by stating the problem, followed by an exposition of the views of Augustine and Calvin on the Fall. As a heuristic key, the concepts of infralapsarism and supralapsarism were applied respectively to analyse the topic. The article concluded with the conviction that the imago Dei is an embodied human person that had biologically emerged in history as a center of self-awareness, and moral responsibility.

    Constitution.The discussion is placed against the background of a so-called blank space in the 1996 Constitution. While the 1993 Constitution characterized South Africa as a "constitutional state", the 1996 does not contain such a characterization. It is argued in this paper that the process phrasing in section 1 (a ties in with a social democratic view of the state as an institution bringing about social change. The "state of affairs" phrasing of section 7(1 is, on the other hand, more in line with a liberal notion of a Rechtsstaat.The issue concerning what type of state South Africa is under the 1996 Constitution, will depend on which of the two poles in the above-mentioned dialectic the primary emphasis will be placed.Since the 1996 Constitution has been ratified by the Constitutional Court, it is regarded as extremely unlikely that the above-mentioned terminological problem will be rectified in future. Swanepoel provides a diagrammatic representation of the principle, values and objectives mentioned in the 1996 Constitution.Further research is envisaged concerning the possibility of developing a juridical model of reconciling the social-democratic and Rechtsstaat tendencies in the 1996 Constitution within the framework of a broader vision on the state’s task in bringing about justice.

    Full Text Available The historical Jesus, the Jesus movement and the birth of the church. The article focuses on the birth of the church. The point at which the church began its existence is located within the boundaries of fonnative Judaism. The parting of the ways is explained as a movement from faction to sect, to the eventual fonnation of the church in its own right as distinct from the synagogue. The historical Jesus should therefore not be seen as the founder of the church. However, the article argues that the relation of the life and death of the historical Jesus to the resurrection belief of the post-paschal Jesus movement constitutes the cradle of the church. This continuum between Jesus and New Testament Christendom is referred to by means of the Gennan phrase die Sache Jesu. Reconsideration of this trajectory results in the conviction that the vision and program of the historical Jesus cannot be neglected when one reflects on the nature of the church in the New Testament or on the vocation of the church through history to the present day. Two thought complexes form the kernel of die Sache Jesu: God's unbounded presence and the concept that everyone has unmediated and non-hierarchical access to the grace of God.

Although drilling results in the first quarter on the Rainbow Lake properties was mixed, oil prices started to free fall and drilling costs were much higher than expected. As a result, the company completed a reduced program which resulted in less incremental loss and cash flow than it budgeted for. On April 29, 1998, Big Bear entered into agreement with Belco Oil and Gas Corp. and Moan Investments Ltd. for the issuance of convertible preferred shares at a gross value of $15,750,000, which shares were eventually converted at 70 cents per share to common equity. As a result of the continued plunge in oil prices, the lending value of the company's assets continued to fall, requiring it to take action in order to meet its financial commitments. Late in the third quarter Big Bear issued equity for proceeds of $11,032,000 which further reduced the company's debt. Although the company has been extremely active in identifying and pursuing acquisition opportunities, it became evident that Belco Oil and Gas Corp. and Big Bear did nor share common criteria for acquisitions, which resulted in the restructuring of their relationship in the fourth quarter. With the future of oil prices in question, Big Bear decided that it would change its focus to that of natural gas and would refocus ts efforts to acquire natural gas assets to fuel its growth. The purchase of Blue Range put Big Bear in a difficult position in terms of the latter's growth. In summary, what started as a difficult year ended in disappointment

    Full Text Available Without trying to distinguish between the subject Afrikaans and the language Afrikaans, and without denying the metaphoric meaning of a statement like ‘Afrikaans is oppressive’, this article investigates the position of Afrikaans among the other ten main languages of South Africa. The idea that Afrikaans is a mere minority language in South Africa is repudiated. Statistical figures indicate that Afrikaans is the language with the largest number of speakers and the third largest mother longue in South Africa. The question as to why Afrikaans is regarded as a minority language - even by its own users - is also touched upon. In this article it is argued that the political system of apartheid has split the language community into two parts and that therefore this community has never been a unity. The future role of Afrikaans in a democratic South Africa will also be determined by the users of Afrikaans, given that the Afrikaans language community could be consolidated. This article argues that the lack of unity within the Afrikaans speech community is mainly the reason for the belief that Afrikaans is, in a statistical sense, a minority language. I f the Afrikaans speech community can be consolidated, Afrikaans will be able to take its natural place among the other ten languages of South Africa. Such a consolidation, however, has to be brought about by those who form this community.

    The potential influence of seed bank composition on range shifts of species due to climate change is unclear. Seed banks can provide a means of both species persistence in an area and local range expansion in the case of increasing habitat suitability, as may occur under future climate change. However, a mismatch between the seed bank and the established plant community may represent an obstacle to persistence and expansion. In big sagebrush (Artemisia tridentata) plant communities in Montana, USA, we compared the seed bank to the established plant community. There was less than a 20% similarity in the relative abundance of species between the established plant community and the seed bank. This difference was primarily driven by an overrepresentation of native annual forbs and an underrepresentation of big sagebrush in the seed bank compared to the established plant community. Even though we expect an increase in habitat suitability for big sagebrush under future climate conditions at our sites, the current mismatch between the plant community and the seed bank could impede big sagebrush range expansion into increasingly suitable habitat in the future.

    Full Text Available Ideological norm replacement and the Afrikaans desk dictionary of the ninetiesIn South Africa the past decade has been marked by extensive sociopolitical changes and by concomitant linguistic changes. These changes may be regarded as instances of norm replacement - a process during the course of which a norm or a set of norms is gradually replaced by another norm or set of norms. It is maintained that the standard synchronic dictionaries of a language not only have the obligation to reflect lexicalised norm replacements, but also to make projections with regard to future use. Two standard synchronic desk dictionaries of Afrikaans, namely the eighth edition of Verklarende Afrikaanse Woordeboek (1992 and the third edition of Verklarende Handwoordeboek van die Afrikaanse Taal (1994 are explored with special regard to their reflection of norm replacements within the domains of race and political ideology. It is shown that the compilers of these dictionaries consciously and sincerely aimed at removing all racial bias but that they failed to record the diversity of meaning within the political lexicon and the semantic shifts which have occurred within that lexicon during the past decade.

    This paper aims to explore key risks and extraneous factors influencing raw material availability and related consequences for the realization of future automotive power trains. Important raw materials for the electro mobility are presented followed by an evaluation of their future supply risk. A review of the current situation and a summary of expectations for future technological developments are presented. The current situation of political factors, access to resources and other important factors are then discussed, highlighting some of the major risks and their influence on up-take rates of alternative power train technologies. Specifically the specific relationships between demand and supply side for specific rare earth elements and their effects on price development is investigated and suggests how these factors might influence existing relationships within the automotive industry. The paper concludes with suggestions for alternative strategies for specific groups within the automotive value chain to mitigate those risks. (orig.)

  13. Curating Big Data Made Simple: Perspectives from Scientific Communities.

    Science.gov (United States)

    Sowe, Sulayman K; Zettsu, Koji

    2014-03-01

    The digital universe is exponentially producing an unprecedented volume of data that has brought benefits as well as fundamental challenges for enterprises and scientific communities alike. This trend is inherently exciting for the development and deployment of cloud platforms to support scientific communities curating big data. The excitement stems from the fact that scientists can now access and extract value from the big data corpus, establish relationships between bits and pieces of information from many types of data, and collaborate with a diverse community of researchers from various domains. However, despite these perceived benefits, to date, little attention is focused on the people or communities who are both beneficiaries and, at the same time, producers of big data. The technical challenges posed by big data are as big as understanding the dynamics of communities working with big data, whether scientific or otherwise. Furthermore, the big data era also means that big data platforms for data-intensive research must be designed in such a way that research scientists can easily search and find data for their research, upload and download datasets for onsite/offsite use, perform computations and analysis, share their findings and research experience, and seamlessly collaborate with their colleagues. In this article, we present the architecture and design of a cloud platform that meets some of these requirements, and a big data curation model that describes how a community of earth and environmental scientists is using the platform to curate data. Motivation for developing the platform, lessons learnt in overcoming some challenges associated with supporting scientists to curate big data, and future research directions are also presented.

    Full Text Available Big data is the term for any gathering of information sets, so expensive and complex, that it gets to be hard to process for utilizing customary information handling applications. The difficulties incorporate investigation, catch, duration, inquiry, sharing, stockpiling, Exchange, perception, and protection infringement. To reduce spot business patterns, anticipate diseases, conflict etc., we require bigger data sets when compared with the smaller data sets. Enormous information is hard to work with utilizing most social database administration frameworks and desktop measurements and perception bundles, needing rather enormously parallel programming running on tens, hundreds, or even a large number of servers. In this paper there was an observation on Hadoop architecture, different tools used for big data and its security issues.

    Full Text Available Big Data analytics has started to impact all types of organizations, as it carries the potential power to extract embedded knowledge from big amounts of data and react according to it in real time. The current technology enables us to efficiently store and query large datasets, the focus is now on techniques that make use of the complete data set, instead of sampling. This has tremendous implications in areas like machine learning, pattern recognition and classification, sentiment analysis, social networking analysis to name a few. Therefore, there are a number of requirements for moving beyond standard data mining technique. Purpose of this paper is to understand various techniques to analysis data.

    Micro-Electro-Mechanical Systems (MEMS) is a big name for tiny devices that will soon make big changes in everyday life and the workplace. These and other types of Microsystems range in size from a few millimeters to a few microns, much smaller than a human hair. These Microsystems have the capability to enable new ways to solve problems in commercial applications ranging from automotive, aerospace, telecommunications, manufacturing equipment, medical diagnostics to robotics, and in national security applications such as nuclear weapons safety and security, battlefield intelligence, and protection against chemical and biological weapons. This broad range of applications of Microsystems reflects the broad capabilities of future Microsystems to provide the ability to sense, think, act, and communicate, all in a single integrated package. Microsystems have been called the next silicon revolution, but like many revolutions, they incorporate more elements than their predecessors. Microsystems do include MEMS components fabricated from polycrystalline silicon processed using techniques similar to those used in the manufacture of integrated electrical circuits. They also include optoelectronic components made from gallium arsenide and other semiconducting compounds from the III-V groups of the periodic table. Microsystems components are also being made from pure metals and metal alloys using the LIGA process, which utilizes lithography, etching, and casting at the micron scale. Generically, Microsystems are micron scale, integrated systems that have the potential to combine the ability to sense light, heat, pressure, acceleration, vibration, and chemicals with the ability to process the collected data using CMOS circuitry, execute an electrical, mechanical, or photonic response, and communicate either optically or with microwaves.

    It was only after James P. Lovette's death, in 2006, that I discovered that the twenty-four-year-old colleague and friend with whom I had spent so many afternoons debating issues in organ transplantation had been the first successful child heart transplantee in the world and one of the longest-living survivors of a second transplant. During the years we met, he never even hinted at the fact that three different hearts had beaten in his chest. The revelation that his life had been an almost uninterrupted chain of medical challenges suddenly made me appreciate his quirkiness in a whole new light. Organ transplantation crudely exemplifies a traditional moral dilemma between means and ends: in order to save a life, someone else has to die. Bioethicists involved in this field have the role of identifying the ethical issues surrounding organ donation and helping others to argue in an intelligible and convincing way. In my view, bioethicists have the obligation to foster a discussion as open and transparent as possible on these matters. Still, I sometimes fear that I may be helping to cause unnecessary harms to potential recipients who are desperately waiting for a vital organ. Scholars would be chillingly cold if their quest for truth systematically came at the cost of lives lost. Every life can be meaningful and provide meaning to many others. This is true even with organ recipients, who often have short lives full of considerable suffering. PMID:25231665

    The future role of coal in the power production is in the area of conflict of economic efficiency, supply reliability, and environmental compatibility. A radical exit from the power generation from coal is not possible due to the actual supply reliability. In order to make coal really dispensable, a large technological breakthrough would have to be obtained with the renewable energies. By means of the consistent conversion of the emission trade system of the European Union, incentives can be created for investing in other technologies for power generation or efficient coal-fired power stations, respectively. Thereby, by means of a full auction of the contamination rate, the trade with carbon dioxide also enables the introduction of technologies for CO{sub 2} separation in the new construction of coal-fired power stations. In order to increase the energy efficiency, this technology can be used as a bridging technology in the transition to renewable energies. Considering the different arguments for and against coal, the following conclusions can be drawn: (a) Also in the future, coal plays a crucial role in the power generation in Germany, Europe and world-wide; (b) Compared with other sources of energy, the largest reserves and resources are proven for coal; (c) Also in the future, coal will clearly be cheaper than natural gas; (d) Coal production, coal transport as well as power generation from coal are environmentally harmful and climatically harmful in a large scale; (e) The European Union wide emissions trading is a suitable instrument for the internationalization of external costs of power generation from coal; (f) The splitting off and storage of CO{sub 2} is a crucial technology option for attaining the long-term climatic goals.

    International Nuclear Information System (INIS)

    We construct phantom energy models with the equation of state parameter w which is less than -1, w<-1, but finite-time future singularity does not occur. Such models can be divided into two classes: (i) energy density increases with time (“phantom energy” without “Big Rip” singularity) and (ii) energy density tends to constant value with time (“cosmological constant” with asymptotically de Sitter evolution). The disintegration of bound structure is confirmed in Little Rip cosmology. Surprisingly, we find that such disintegration (on example of Sun-Earth system) may occur even in asymptotically de Sitter phantom universe consistent with observational data. We also demonstrate that non-singular phantom models admit wormhole solutions as well as possibility of Big Trip via wormholes.

    1964-03-01

    Full Text Available Die vrye wêreld het sedert die oorloggedwonge opskorting van die goudstandaard in 1914, ’n groot agteruitgang in die internasionale betalingsmeganisme beleef. Hoewel die inter- nasionale goudstandaard in die laaste helfte van die twintiger- jare herstel is, was meeste lande nie langer gedwee om hulle aan die monetêre dissipline van dié stelsel te onderwerp nie en vind ons dat die een land na die ander onder die druk van die depressie in die dertigerjare die goudstandaard laat vaar het. Die Verenigde State van Amerika was die enigste uitson- dering. Geleidelik moes wisselkoersstabiliteit en die vrye inter­ nasionale betalingsverkeer vir wisselkoersmanipulasie en valu- tabeheer plek maak. Hierdie transformasie was ’n weerspieë- ling van die sterker opkoms van ekonomiese nasionalisme en die begeerte van die onderskeie lande om elkeen vir homself die beste voordeel in die internasionale ekonomiese en finan- siële terrein toe te eien. Die daarstelling van die Internasionale Monetêre Fonds te Bretton Woods in 1944, was ’n simptoom van die wêreldwye kommer oor die vooroorlogse neigings op monetêre gebied en terselfdertyd ’n poging om meer dissi­ pline in die internasionale betalingsverkeer te skep. Feit is egter dat ondanks sy positiewe resultate op sommige gebiede, die Internasionale Monetêre Fonds nie heeltemal 'n geskikte substituut vir die goudstandaard daargestel het nie. Wat meer is, die skok van die internasionale monetêre steurnisse word nog steeds deur die lande met die internasionale geldeenhede, naamlik die pond sterling en die dollar ondervind.

    The elevation change data measured at the Big Hill SPR site over the last 10 years has been studied and a model utilized to project elevation changes into the future. The subsidence rate at Big Hill is low in comparison with other Strategic Petroleum Reserve sites and has decreased with time due to the maintenance of higher operating pressures and the normal decrease in creep closure rate of caverns with time. However, the subsidence at the site is projected to continue. A model was developed to project subsidence values 20 years into the future; no subsidence related issues are apparent from these projections.

    Full Text Available Although a number of research studies support Locke's goal setting theory, conflicting results are encountered in the Literature which suggest further investigation into the subtleties of the theory. The results of this study indicate that an increase in goal-difficulty does not always lead to a corresponding increase in performance. The latter could also not be explained in terms of the degree of goal-acceptance as an intervening variable. It was found that financial incentives and the way in which a nonspecific goal is formulated could have a significant effect on performance. Recommendations are made for future research.OpsommingOfskoon die meeste navorsing Locke se doelwitstellingsteorie ondersteun, is bepaalde afwykings teengekom wat nie op 'n bevredigende wyse verklaar kan word nie. Die resultate van hierdie studie dui daarop dat 'n toename in doelwitmoeilikheidsgraad nie altyd tot ‘n ooreenstemmende toename in prestasie lei nie. Hierdie resultaat kon ook nie op grond van 'n gebrek aan doelwitaanvaarding verklaar word nie. Daar is voorts gevind dat die wyse waarop 'n nie-spesifieke doelwit gestel word, 'n beduidende invloed op prestasie kan hê. Finansiële aansporings blyk ook 'n onafhanklike invloed op prestasie te hê. Bepaalde aspekte van Locke se teorie word dus deur bogenoemde resultate bevraagteken. Aanbevelings vir verdere navorsing word ten slotte gedoen.

    Full Text Available Die argument word gehoor dat kerkregeringstelsels soos dié van die Rooms-Katolieke, Lutherse en gereformeerde kerke van ’n transendentale aard was en is. Daardeur word geïmpliseer dat hierdie stelsels een transendentale, unieke vaste beginsel gebruik om ’n hele stelsel van kerkregering van buite af te bepaal. Volgens Leo Koffeman, ’n voorstander van ’n ekumeniese kerkreg, plaas hierdie stelsels hulself hiermee buite die diskoers oor kerkreg en kerkregering en die beweging van die Heilige Gees. ’n Ekumeniese kerkreg, daarenteen, is ten gunste van ’n gemeenskaplike kerkreg tussen kerke. Omdat dit verskillende tradisies bymekaar bring, is dit ’n kritiese en daarom beter benadering. Die skrywer oorweeg hierdie argumente krities in die lig van ’n gereformeerde benadering tot kerkreg.The argument is used that church political systems like that of the Roman Catholic, Lutheran and reformed churches were of a transcendental character. By that it is implied that it used one transcendental and unique ‘hard principle’ from outside to direct a system of church government. Such uniqueness, according to Leo Koffeman who advocates an ecumenical church polity, places it outside the church political discourse and the way of the Holy Spirit. An ecumenical church polity seeks a combined polity between churches and is, by bringing different traditions together, a critical and therefore better undertaking. The author examines these arguments critically in the light of a reformed church polity.

Das Korpus der gesprochenen Texte bilden 30 Dankesreden anlässlich kroatischer Preisverleihungen in den Bereichen Schauspiel, Sport, Musik, Fernsehen, Literatur und Wirtschaft. Die Audio-Aufnahmen der Dankesreden wurden einer Gruppe von Hörern zur Bewertung in folgenden Kategorien vorgelegt: interessant, geistreich, hoher Sprachstil, feierlich, emotiv, persönlich, originell, bescheiden, vorbereitet und spontan. Zusätzlich wurde zu jeder Rede die offene Frage gestellt, was dem Zuhörer an der Rede gefallen oder nicht gefallen habe. Die Resultate der Perzeptionsanalye lassen erkennen, dass die Interessantheit einer Rede mit der Eigenschaft des Geistreichen, des Originellen, des Emotionalen und des Persönlichen in Verbindung gebracht wird und die Eigenschaft des Festlichen im Wesentlichen nur mit dem hohen Sprachstil und der Vorbereitetheit des Textes korreliert. Einige Eigenschaften können sowohl erwünscht als auch unerwünscht sein, z. B. Dialekt, Persönliches und Kürze. Die besten Dankesreden haben Eigenschaften, die im Grunde schwer miteinander zu verbinden sind: Einerseits soll der Text vorbereitet sein (hoher Stil, Wortwahl, Figuren, Originalität der Geschichte, Humor, andererseits wird bei der Ausführung Spontaneität (Aufrichtigkeit, Emotionalität, Persönlichkeit erwartet.

    The energy savings division at the discount store Aldi Sued in Rastatt should in the future only need two-thirds of the primary energy usually required for refrigeration, heating, ventilation, air conditioning and lighting. A compressor pack with carbon dioxide as a coolant which has been developed in-house, and which is coupled to borehole heat exchangers, not only cools food, but also provides temperature control for indoor areas. The energy concept, which has been developed at the ISE Fraunhofer Institute for Solar Energy Systems, is rounded off by a well insulated building envelope, the use of daylight and efficient ventilation. In the third year of operation, the amount of energy consumed is coming close to the ambitious target levels. (orig.)

    How Big is Earth celebrates the Year of Light. Using only the sunlight striking the Earth and a wooden dowel, students meet each other and then measure the circumference of the earth. Eratosthenes did it over 2,000 years ago. In Cosmos, Carl Sagan shared the process by which Eratosthenes measured the angle of the shadow cast at local noon when sunlight strikes a stick positioned perpendicular to the ground. By comparing his measurement to another made a distance away, Eratosthenes was able to calculate the circumference of the earth. How Big is Earth provides an online learning environment where students do science the same way Eratosthenes did. A notable project in which this was done was The Eratosthenes Project, conducted in 2005 as part of the World Year of Physics; in fact, we will be drawing on the teacher's guide developed by that project.How Big Is Earth? expands on the Eratosthenes project by providing an online learning environment provided by the iCollaboratory, www.icollaboratory.org, where teachers and students from Sweden, China, Nepal, Russia, Morocco, and the United States collaborate, share data, and reflect on their learning of science and astronomy. They are sharing their information and discussing their ideas/brainstorming the solutions in a discussion forum. There is an ongoing database of student measurements and another database to collect data on both teacher and student learning from surveys, discussions, and self-reflection done online.We will share our research about the kinds of learning that takes place only in global collaborations.The entrance address for the iCollaboratory is http://www.icollaboratory.org.

The abundances of the primordial isotopes D, He-3, and Li-7 produced in standard BBN can be calculated as a function of the baryon density with an accuracy of about 10%. For He-4 the accuracy is better than 1%. The calculated abundances agree fairly well with observations, but the baryon density of the universe cannot be determined with high precision. Possibilities for nonstandard BBN include inhomogeneous and antimatter BBN and nonzero neutrino chemical potentials.

    Objective Electronic health records (EHRs) may contain infomarkers that identify patients near the end of life for whom it would be appropriate to shift care goals to palliative care. Discovery and use of such infomarkers could be used to conduct effectiveness research that ultimately could help to reduce the monumental costs for dying care. Our aim was to identify changes in the plans of care that represented infomarkers, which signaled the transition of care goals from non-palliative care goals to those consistent with palliative care. Methods Using an existing electronic health record database generated during a two-year, longitudinal study of 9 diverse medical-surgical units from 4 Midwest hospitals and a known group approach, we evaluated the patient care episodes for 901 patients who died (mean age=74.5±14.6 years). We used ANOVA and Tukey’s post-hoc tests to compare patient groups. Results We identified 11 diagnoses, including Death Anxiety and Anticipatory Grieving, whose addition to the care plan, some of which also occurred with removal of non-palliative care diagnoses, represent infomarkers of transition to palliative care goals. There were four categories of patients, those who had: no infomarkers on plans (n=507); infomarkers added on the admission plan (n=194); infomarkers added on a post admission plan (minor transitions, n=109), and infomarkers added and non-palliative care diagnoses removed on a post admission plan (major transition, n=91). Age, length of stay, and pain outcomes differed significantly for these four categories of patients. Significance of Results EHRs contain pertinent infomarkers that if confirmed in future studies could be used for timely referral to palliative care for improved focus on comfort outcomes and to identify palliative care subjects from data repositories for to conduct big data research, comparative effectiveness studies, and health services research.

The results of this expert surveys are described in the contribution under consideration: (1) The vast majority of climate scientists says that limiting global warming to two degrees celsius only is possible if the developed industrial countries reduce their emissions by 80 % compared to the year 1990; (2) This inevitably requires interventions of the policy for sustainable management; (3) Despite the economic and financial crisis the policy shall not ease its ambitious targets in the medium term; (4) The threat of global warming is a global problem. The solution of this problem at political level requires a more advanced form of 'global governance'; (5) A significant increase in the petroleum price may affect the globally distributed industrial 'settlement structures' and the configuration of logistics networks. A possible adaptation may consist in multistage distribution systems with regional, customer-oriented stocks; (6) A stronger focus of companies to a low-polluting, sustainable business can be facilitated and supported by financial incentives; (7) It is not expected that professional buyers of companies do not sacrifice price advantages in low-wage countries; (8) Scale effects in the production by special factories result in a continuation of the current 'production footprints' even if this model significantly increases the transport intensity of the economy due to the longer distance between the place of production and the place of consumption; (9) In the logistics presumable there exists any other single measure to eliminate many pollutants such as the replacement of air cargo by sea freight; (10) Economic-historically, globalization has developed very quickly. The experts disagree on whether globalization slows down or whether the globalization changes at a constant speed.

Unlike modern Western societies, Mediterranean peasant societies had the present as first-order temporary preference. Secondary preference is past, and the future comes as third choice. According to a social-scientiic model of Mediterranean time, the present and past can be understood as expeienced time, as well as cyclical and processual time. The future is viewed as imaginary time. These insights are especially crucial for understanding the day of the Lord in 2 Peter within the context of the delay of the parousia, winch is of primary concern to the author of 2 Peter. The author advocates the shiting of the parousia from the present to the far-of future of an imaginary time of God's control. As a result, his ethics for the present was sill strongly influenced by the day of the Lord. In contrast, the author's opponents' untidyethics reflected their rejecion of the relevancy of the future parousia fortheir present lives.

    Radiation therapy is a first-line treatment option for localized prostate cancer and radiation-induced normal tissue damage are often the main limiting factor for modern radiotherapy regimens. Conversely, under-dosing of target volumes in an attempt to spare adjacent healthy tissues limits the likelihood of achieving local, long-term control. Thus, the ability to generate personalized data-driven risk profiles for radiotherapy outcomes would provide valuable prognostic information to help guide both clinicians and patients alike. Big data applied to radiation oncology promises to deliver better understanding of outcomes by harvesting and integrating heterogeneous data types, including patient-specific clinical parameters, treatment-related dose-volume metrics, and biological risk factors. When taken together, such variables make up the basis for a multi-dimensional space (the "RadoncSpace") in which the presented modeling techniques search in order to identify significant predictors. Herein, we review outcome modeling and big data-mining techniques for both tumor control and radiotherapy-induced normal tissue effects. We apply many of the presented modeling approaches onto a cohort of hypofractionated prostate cancer patients taking into account different data types and a large heterogeneous mix of physical and biological parameters. Cross-validation techniques are also reviewed for the refinement of the proposed framework architecture and checking individual model performance. We conclude by considering advanced modeling techniques that borrow concepts from big data analytics, such as machine learning and artificial intelligence, before discussing the potential future impact of systems radiobiology approaches.

    It is shown in this paper that minisuperspace quantization of homogeneous and isotropic geometries with phantom scalar fields, when examined in the light of the Bohm-de Broglie interpretation of quantum mechanics, does not eliminate, in general, the classical big rip singularity present in the classical model. For some values of the Hamilton-Jacobi separation constant present in a class of quantum state solutions of the Wheeler-De Witt equation, the big rip can be either completely eliminated or may still constitute a future attractor for all expanding solutions. This is contrary to the conclusion presented in [M. P. Dabrowski, C. Kiefer, and B. Sandhofer, Phys. Rev. DPRVDAQ1550-7998 74, 044022 (2006).10.1103/PhysRevD.74.044022], using a different interpretation of the wave function, where the big rip singularity is completely eliminated (“smoothed out”) through quantization, independently of such a separation constant and for all members of the above mentioned class of solutions. This is an example of the very peculiar situation where different interpretations of the same quantum state of a system are predicting different physical facts, instead of just giving different descriptions of the same observable facts: in fact, there is nothing more observable than the fate of the whole Universe.

    Full Text Available Die doel van hierdie studie was om hoofplantegroei-eenhede en hulle variasies, van die A-landtipe, te identifiseer, karakteriseer en aan die hand van die habitat ekologies te interpreteer. Vyf plantgemeenskappe is deur die toepassing van 'n numeriese klassifikasie en Braun-Blanquet-prosedures geidentifiseer en elk is met ’n spesifieke habitat gekorreleer. 'n Duidelike onderskeid is tussen die hoogliggende en die laagliggende plantgemeenskappe gemaak. Plantegroeigradiënte en geassosieerde gradiënte in habitat is deur toepassing van ’n ordeningstegniek geidentifiseer. Die studie beklemtoon die belangrikheid van topografie en grondtipe vir die afbakening van plantegroei-bestuurseenhede vir boerdery of natuurbewaring.

  17. SETI as a part of Big History

    Science.gov (United States)

    Maccone, Claudio

    2014-08-01

    Big History is an emerging academic discipline which examines history scientifically from the Big Bang to the present. It uses a multidisciplinary approach based on combining numerous disciplines from science and the humanities, and explores human existence in the context of this bigger picture. It is taught at some universities. In a series of recent papers ([11] through [15] and [17] through [18]) and in a book [16], we developed a new mathematical model embracing Darwinian Evolution (RNA to Humans, see, in particular, [17] and Human History (Aztecs to USA, see [16]) and then we extrapolated even that into the future up to ten million years (see 18), the minimum time requested for a civilization to expand to the whole Milky Way (Fermi paradox). In this paper, we further extend that model in the past so as to let it start at the Big Bang (13.8 billion years ago) thus merging Big History, Evolution on Earth and SETI (the modern Search for ExtraTerrestrial Intelligence) into a single body of knowledge of a statistical type. Our idea is that the Geometric Brownian Motion (GBM), so far used as the key stochastic process of financial mathematics (Black-Sholes models and related 1997 Nobel Prize in Economics!) may be successfully applied to the whole of Big History. In particular, in this paper we derive Big History Theory based on GBMs: just as the GBM is the “movie” unfolding in time, so the Statistical Drake Equation is its “still picture”, static in time, and the GBM is the time-extension of the Drake Equation. Darwinian Evolution on Earth may be easily described as an increasing GBM in the number of living species on Earth over the last 3.5 billion years. The first of them was RNA 3.5 billion years ago, and now 50

    Full Text Available It is aware that big data has gathered tremendous attentions from academic research institutes, governments, and enterprises in all aspects of information sciences. With the development of diversity of marine data acquisition techniques, marine data grow exponentially in last decade, which forms marine big data. As an innovation, marine big data is a double-edged sword. On the one hand, there are many potential and highly useful values hidden in the huge volume of marine data, which is widely used in marine-related fields, such as tsunami and red-tide warning, prevention, and forecasting, disaster inversion, and visualization modeling after disasters. There is no doubt that the future competitions in marine sciences and technologies will surely converge into the marine data explorations. On the other hand, marine big data also brings about many new challenges in data management, such as the difficulties in data capture, storage, analysis, and applications, as well as data quality control and data security. To highlight theoretical methodologies and practical applications of marine big data, this paper illustrates a broad view about marine big data and its management, makes a survey on key methods and models, introduces an engineering instance that demonstrates the management architecture, and discusses the existing challenges.

    We report on the possibility to use dark matter mass and its interaction cross section as a smoking gun signal of the existence of a big bounce at the early stage in the evolution of our currently observed universe. A model independent study of dark matter production in the contraction and expansion phases of the bounce universe reveals a new venue for achieving the observed relic abundance in which a significantly smaller amount of dark matter--compared to the standard cosmology--is produced and survives until today, diluted only by the cosmic expansion since the radiation dominated era. Once DM mass and its interaction strength with ordinary matter are determined by experiments, this alternative route becomes a signature of the bounce universe scenario.

    Big Data brings unprecedented power to address scientific, economic and societal issues, but also amplifies the possibility of certain pitfalls. These include using purely data-driven approaches that disregard understanding the phenomenon under study, aiming at a dynamically moving target, ignoring critical data collection issues, summarizing or preprocessing the data inadequately and mistaking noise for signal. We review some success stories and illustrate how statistical principles can help obtain more reliable information from data. We also touch upon current challenges that require active methodological research, such as strategies for efficient computation, integration of heterogeneous data, extending the underlying theory to increasingly complex questions and, perhaps most importantly, training a new generation of scientists to develop and deploy these strategies.

    As one of the very few people in the world to give the “go/no go” decision to detonate a nuclear device, Austin “Mac” McGuire holds a very special place in the history of both the Los Alamos National Laboratory and the world. As Commander of Joint Task Force Unit 8.1.1, on Christmas Island in the spring and summer of 1962, Mac directed the Los Alamos data collection efforts for twelve of the last atmospheric nuclear detonations conducted by the United States. Since data collection was at the heart of nuclear weapon testing, it fell to Mac to make the ultimate decision to detonate each test device. He calls his experience THE LAST BIG BANG, since these tests, part of Operation Dominic, were characterized by the dramatic displays of the heat, light, and sounds unique to atmospheric nuclear detonations – never, perhaps, to be witnessed again.

  6. Big Bang Darkleosynthesis

    CERN Document Server

    Krnjaic, Gordan

    2014-01-01

    In a popular class of models, dark matter comprises an asymmetric population of composite particles with short range interactions arising from a confined nonabelian gauge group. We show that coupling this sector to a well-motivated light mediator particle yields efficient darkleosynthesis, a dark-sector version of big-bang nucleosynthesis (BBN), in generic regions of parameter space. Dark matter self-interaction bounds typically require the confinement scale to be above \\Lambda_{QCD}, which generically yields large (>>MeV/dark-nucleon) binding energies. These bounds further suggest the mediator is relatively weakly coupled, so repulsive forces between dark-sector nuclei are much weaker than coulomb repulsion between standard-model nuclei, which results in an exponential barrier-tunneling enhancement over standard BBN. Thus, dark nuclei are easier to make and harder to break than visible species with comparable mass numbers. This process can efficiently yield a dominant population of states with masses signifi...

The following aspects are addressed: the origin and content of the Confession of Belhar, the ecclesiastical and theological reaction within the family of Dutch Reformed Churches as well as in the reformed ecumenical world. A critical analysis of the content is made and evaluated, and in con- clusion attention is given to a few options with regard to the place of the Confession of Belhar in the reformed ecumenical world in the future. A comparison between the Three Forms of Unity and the Confession of Belhar shows a definite difference in quality. The Confession of Belhar is not of a similar standard with regard to the theological and doctrinal content and structure of the Three Forms of Unity, and does not add quality or neglected faith-related value to these existing creeds.

Anhand zweier jeweils sehr unterschiedlicher Beispiele „weiblicher“ Filmkunst zeigt die Autorin, dass es nötig ist, herkömmliche Interpretationsmuster zu überwinden, um dem Filmschaffen einzelner Künstler und Künstlerinnen auf den Grund zu gehen. Da es nicht die „feministische Kunst“ an sich gibt, muß man für das Werk so unterschiedlicher Künstlerinnen wie Sally Potter und Jane Campion jeweils unterschiedliche Schlüssel suchen, um ihnen gerecht zu werden. Dies tut Radkiewicz in ihrem Werk – aus feministischer Perspektive.

    Full Text Available Met die 450e herdenking van die Heidelbergse Kategismus as vertrekpunt, word met die huidige en die vorige artikel gepoog om lig te werp op die plek, die rol en die interpretasie van die opstanding van Jesus Christus in veral Sondag 17 en 22, spesifiek in die konteks van twee besondere eras in die Nederduitse Gereformeerde (NG Kerk. In die vorige artikel is allereers ’n bespreking gevoer oor die Heidelbergse Kategismus (HK. Daar is gekyk na die resepsie van die betrokke HK-geloofsartikels in die era van Andrew Murray, spesifiek teen die agtergrond van die negentiende-eeuse liberale teologie in Nederland. In die huidige artikel word soortgelyk gekyk na die resepsie van die betrokke HK-geloofsartikels in die NG Kerk na 2000, teen die agtergrond van die herverskyning van die negentiende-eeuse liberale teologie in die vorm van die Jesus Seminaar, die Nuwe Hervorming en ondersteuners daarvan binne die NG Kerk. Sowel die negentiende-eeuse liberale stryd in die NG Kerk asook die stryd oor die opstanding in die NG Kerk van die eerste dekade van die een-en-twintigste eeu, soos verder in hierdie artikel sal blyk, was gekenmerk deur kontekstueelbepaalde uniekhede. Die gemene deler was dat albei deel was van tye van teologiese vrysinnigheid. In die lig van hierdie bespreking word tot die gevolgtrekking gekom dat die NG Kerk tans, betreffende haar identiteit as gereformeerde kerk waarskynlik in ’n kritieke geloofs- en toekomskrisis verkeer. Dit impliseer kommerwekkende gevolge vir haar Skrifverstaan en getuienis as belydenis en belydende kerk van Jesus Christus en haar toekoms.

Die etiese relevansie is ingebed in die konfessie se verklaring van die tien gebooie. Die artikel verduidelik dat die etiek van die Heidelbergse Kategismus ten diepste ’n karakteretiek is en dat dit gelowiges oproep tot ’n etiek van liefde. Hierdie liefde sluit in liefde vir die verbondsgemeenskap, die bediening van die Woord, die heiligheid van God en die waardigheid van mense, die gemeenskap van die gelowiges, gesag, die lewe, die huwelik, privaatbesit en arbeid asook waarheid en geregtigheid. As gevolg van die sinekdogeekarakter van die wet is hierdie etiek van liefde vandag baie relevant.This article deals with the ethical relevance of one of the prominent confessions in the reformed tradition, namely the Heidelberg Cathechism. The ethical relevance lies in the confession’s elucidation of the ten commandments and its application to moral conduct. The article explains that the ethics of the Heidelberg Catechism is essentially a virtue ethics calling for an ethics of love. This love should include love for the covenantal communion, ministry of the Word, the holiness of God and the dignity of people, the communion of the saints, authority, life, marriage, private property and labour, and truth and justice. Due to the synecdochical character of the ten commandments this ethics of love is highy relevant in the present times.

    This paper examines the recent prominent view in medical ethics that withdrawing life-sustaining treatment (LST) is an act of killing. I trace this view to the rejection of the traditional claim that withdrawing LST is an omission rather than an act. Although that traditional claim is not as problematic as this recent prominent view suggests, my main claim is that even if we accepted that withdrawing LST should be classified as an act rather than as an omission, it could still be classified as letting die rather than killing. Even though omissions are contrasted with acts, letting die need not be, for one can let die by means of acts. The remainder of the paper is devoted to establishing this claim and addresses certain objections to it.

A cursory glance at andragogy creates the impression that humanistic learning theory plays an all encompassing role in the learner centered approach andragogy espouses. A closer look, however, reveals that Knowles (1973, after having made an intensive study of learning theory, created an extensive framework within which human resource development can take place. The fact that Knowles attracted critique from different areas, led to a need to ascertain the role different learning theories, if any, played in the emergence of andragogy. Having looked at the assumptions displayed by the andragogical approach, as well as a comparison of different learning theories and their connection with andragogy, it became clear that andragogy contains elements of various learning theories in an adapted way. These adaptations resulted in an approach to adult education in which learners are given the opportunity to be part of the learning process in such a way that they themselves contribute to the development which takes place. Opsomming Met 'n eerste oogopslag wil dit voorkom asof humanistiese leerteorie 'n oorheersende rol in die leerdergesentreerde benadering van andragogie speel. By nadere ondersoek blyk dit egter dat Knowles (1973, na 'n deeglike studie van verskillende leerteoretiese beginsels, 'n omvangryke raamwerk geskep het waarbinne, aan die hand van verskeie aangepaste leerteoretiese beginsels, menslike hulpbronontwikkeling kan plaasvind. As gevolg van die feit dat Knowles vanuit verskillende oorde kritiek op die lyf geloop het, is besluit om die rol wat verskillende leerteorieë in andragogie speel, te bestudeer. Dit blyk dat andragogie nie net elemente van verskillende leerteorieë bevat nie, maar dat toepaslike aspekte van die teoriee wat ondersoek is, benut en aangepas is om 'n geintegreerde benadering te bewerkstellig waarin veral volwassene-leerders by leergeleenthede en hulle selfontwikkeling betrek word.

    Full Text Available The end of the world: The challenge of modern science to traditional eschatology. In biblical times the ‘Word of God’ indicated God’s creative and redemptive response to changing human predicaments and depravations. Redemptive events became traditions that were applied to new situations. Many biblical future expectations lost their relevance and plausibility already within canonical history. Modern science has rendered a literal interpretation of the most recent and radical biblical future expectations – resurrection and a ‘new heaven and earth’ – problematic. Apocalyptic deliberately employed enigmatic symbols and metaphors to indicate God’s miraculous intervention to change an evil world into a new and authentic reality. This motif can be reconceptualised as God’s vision for the comprehensive optimal well-being of humanity within the well-being of creation as a whole, which translates into God’s concern for any deficiency in well-being in any dimension of life. The emergence of the notion of resurrection to face judgement was rooted in concern about God’s justice (theodicy rather than the longing for never-ending life. The resurrection of Jesus was deemed God’s affirmation of his messianic authority to proclaim and enact God’s redeeming love, thus its validity for all times and places – which opened up participation in the new life of Christ in fellowship with God for all people.

    Full Text Available In die Grieks-Romeinse era het mediese behandeling kenmerkend uit drie elemente bestaan, naamlik regimen (dieet en gesonde leefwyse, geneesmiddels en chirurgie – laasgenoemde alleen toegepas indien regimen en geneesmiddels onsuksesvol was. Bewyse van primitiewe chirurgie dateer terug na die Bronstydperk, en in Homerus se eposse is heelwat vermelding van die chirurgiese hantering van oorlogswonde, met tussenkoms van die gode. Met die koms van empiriese geneeskunde in die 5de eeu v.C. het chirurgie in die Hippokratiese Corpus prominent gefigureer met beduidende bydraes in veral die ortopediese veld en hoofbeserings. Uitbouing van anatomiese en fisiologiese kennis, gebaseer op disseksie van menslike kadawers in Alexandrië vanaf die laat 4de eeu v.C., het chirurgie ’n hupstoot gegee. Teen die Romeinse era vanaf die 2de eeu v.C. het snykundetegnieke (en -instrumente beduidend verbeter, maar is steeds oorwegend deur Griekse geneeshere beoefen. Van geneeshere is steeds verwag om al drie bovermelde terapeutiese modaliteite te bemeester, maar chirurgie het meer aansien verwerf en daar is al meer in onderafdelings van chirurgie soos oogheelkunde, vrouesiektes en verloskunde, blaaskwale en mond- en keelsnykunde gespesialiseer. Militêre geneeskunde was in die Romeinse Ryk ’n belangrike aktiwiteit, en het veral traumachirurgie uitgebou. Betreding van die buik- en toraksholtes was nie meer noodwendig fataal nie, en veeartsenykunde het tot stand gekom. Die eerste beduidende chirurgiehandboek ná die Hippokratiese Corpus is in die 1ste eeu n.C. deur Celsus opgestel. Vanaf die 3de eeu het die chirurgieberoep min vordering gemaak, die beroepstaal het mettertyd van Grieks na Latyn verander en kundigheid is later veral deur Islam-geneeshere na die Middeleeue en later oorgedra.

    We point out a new phenomenon which seems to be generic in 4d effective theories of scalar fields coupled to Einstein gravity, when applied to cosmology. A lift of such theories to a Weyl-invariant extension allows one to define classical evolution through cosmological singularities unambiguously, and hence construct geodesically complete background spacetimes. An attractor mechanism ensures that, at the level of the effective theory, generic solutions undergo a big crunch/big bang transition...

For free fields in our construction there is no particle production from the incoming adiabatic vacuum. When interacti...

The key was identifying a sufficient number of finite, Weyl-invariant conserved quantities to uniquely match the fundamental cosmological degrees of freedom across the transition. In so ...

  3. Dying cancer patients talk about euthanasia.

    Science.gov (United States)

    Eliott, Jaklin A; Olver, Ian N

    2008-08-01

    Within developed nations, there is increasing public debate about and apparent endorsement of the appropriateness of euthanasia as an autonomous choice to die in the face of intolerable suffering. Surveys report socio-demographic differences in rates of acceptance of euthanasia, but there is little in-depth analysis of how euthanasia is understood and positioned within the social and moral lives of individuals, particularly those who might be considered suitable candidates-for example, terminally-ill cancer patients. During discussions with 28 such patients in Australia regarding medical decisions at the end of life, euthanasia was raised by 13 patients, with the others specifically asked about it. Twenty-four patients spoke positively of euthanasia, 19 of these voicing some concerns. None identified euthanasia as a currently favoured option. Four were completely against it. Endorsement for euthanasia was in the context of a hypothetical future or for a hypothetical other person, or temporally associated with acute pain. Arguments supporting euthanasia framed the issue as a matter of freedom of choice, as preserving dignity in death, and as curbing intolerable pain and suffering, both of the patient and of those around them. A common analogy featured was that of euthanising a dog. These arguments were typically presented as self-evident justification for euthanasia, construed as an appropriate choice to die, with opposers positioned as morally inferior or ignorant. The difficulties of ensuring 'choice' and the moral connotations of 'choosing to die,' however, worked to problematise the appropriateness of euthanising specific individuals. We recommend further empirical investigation of the moral and social meanings associated with euthanasia.

Behalwe die feit dat die Italianers nie onmiddellik van die aanmars geweet het nie, het die Hertog van Aosta in 'n rapport aan die Italiaanse weermagshoofkwartier in Rome te kenne gegee dat die lugmag nie kon optree nie weens 'n tekort aan vliegtuie.

    Full Text Available Hoërordedenkvaardighede is noodsaaklike basiese vaardighede vir die een-en-twintigste eeu aangesien rekenaars berekeninge en algoritmes baie vinniger en akkurater kan doen as mense. Dit beteken dat skole leerders moet toerus om logies te dink, patrone te ontdek, bewyse te lewer, asook om nieroetineprobleme op te los. Hierdie fasette wat as hoërordedenke geklassifiseer word, is die kern van wiskundige denke en ontwikkeling. Suid-Afrika neem aan verskeie internasionaal vergelykende studies deel. Met behulp van hierdie vergelykende studies kan bepaal word hoe die Afrikaanse wiskundeleerders in Suid-Afrika se prestasie met dié van leerders in ander lande vergelyk en ook wat die tekortkominge in die wiskundeonderwys is. Volgens die 2003-TIMSS-uitslae is die probleem in Afrikaanse skole juis dié vrae wat hoërordedenke vereis. Dit beteken dat die Afrikaanse skole ’n doelbewuste poging sal moet aanwend om hoërordedenke te ontwikkel. Die 1999-TIMSS-videostudie toon dat die lande wat die beste presteer, soos Japan, tydens onderrig meer tyd wy aan die ontwikkeling van begripsvorming en aan die oplos van moeiliker probleme. Die fokus in die presterende lande is op die ontwikkeling van hoërordedenke deur probleemoplossing. Daar word dus minder tyd afgestaan aan herhaling van roetine- of soortgelyke oefeninge wat ’n rekenaar ook kan doen. Die omgekeerde hiervan is ’n tipiese verskynsel in Afrikaanse skole, waar ’n onderwyser byvoorbeeld een of meer voorbeelde op die bord doen waarna die leerders ’n hele aantal soortgelyke roetine-oefeninge doen.

    Gordan Krnjaic

    2015-12-01

    Full Text Available In a popular class of models, dark matter comprises an asymmetric population of composite particles with short range interactions arising from a confined nonabelian gauge group. We show that coupling this sector to a well-motivated light mediator particle yields efficient darkleosynthesis, a dark-sector version of big-bang nucleosynthesis (BBN, in generic regions of parameter space. Dark matter self-interaction bounds typically require the confinement scale to be above ΛQCD, which generically yields large (≫MeV/dark-nucleon binding energies. These bounds further suggest the mediator is relatively weakly coupled, so repulsive forces between dark-sector nuclei are much weaker than Coulomb repulsion between standard-model nuclei, which results in an exponential barrier-tunneling enhancement over standard BBN. Thus, darklei are easier to make and harder to break than visible species with comparable mass numbers. This process can efficiently yield a dominant population of states with masses significantly greater than the confinement scale and, in contrast to dark matter that is a fundamental particle, may allow the dominant form of dark matter to have high spin (S≫3/2, whose discovery would be smoking gun evidence for dark nuclei.

    Full Text Available A full understanding of and a competent approach to dying patients may lead to a more qualitative service delivery, an enhanced quality of life paradigms, and the patients’ wellbeing, all of which remain the ultimate goal of health care practice. The modern world has developed in parallel with secularism and religious diversity. This paper aims to illustrate the secularization process in Britain (with indications of generalized meanings and juxtaposes it with a description of the needs of dying patients regarding the meanings of religion and nonreligion. Although this paper draws on and provides a review of selected theoretical literature, it also addresses a significant challenge: the lack of scientifi c research on the subject. Hence, this paper aims to give an overview of the issues, but not synthesise them. The arguments that are elaborated in the paper are also supported by the author’s current research project in the city of London. The approach here is client oriented, and concerns social and health care. Practitioners ought to become competent, and maintain their competence throughout their professional career. Religious competence seems to have not been at the centre of discussions, regardless of the historical pathway that religious discourse has drawn since the beginnings of humanity. The paper concludes with certain suggestions for future research and inclusive approaches regarding religious matters.

    Big Data bring new opportunities to modern society and challenges to data scientists. On one hand, Big Data hold great promises for discovering subtle population patterns and heterogeneities that are not possible with small-scale data. On the other hand, the massive sample size and high dimensionality of Big Data introduce unique computational and statistical challenges, including scalability and storage bottleneck, noise accumulation, spurious correlation, incidental endogeneity, and measurement errors. These challenges are distinguished and require new computational and statistical paradigm. This article gives overviews on the salient features of Big Data and how these features impact on paradigm change on statistical and computational methods as well as computing architectures. We also provide various new perspectives on the Big Data analysis and computation. In particular, we emphasize on the viability of the sparsest solution in high-confidence set and point out that exogeneous assumptions in most statistical methods for Big Data can not be validated due to incidental endogeneity. They can lead to wrong statistical inferences and consequently wrong scientific conclusions.

    Human space flight has struggled to find its soul since Apollo. The astounding achievements of human space programs over the 40 years since Apollo have failed to be as iconic or central to society as in the 1960s. The paper proffers a way human space flight could again be associated with a societal Big Idea. It describes eight societal factors that have irrevocably changed since Apollo; then analyzes eight other factors that a forward HSF Big Idea would have to fit. The paper closes by assessing the four principal options for HSF futures against those eight factors. Robotic and human industrialization of geosynchronous orbit to provide unlimited, sustainable electrical power to Earth is found to be the best candidate for the next Big Idea.

We investigate the extent to which big data analytics has the power to change the competitive landscape of industries that could offer operational, strategic and competitive advantages. This paper is based upon a qualitative study of the convergence of predictive analytics and big data in the field of supply chain management. Our findings indicate a need for manufacturers to introduce analytics tools, real-time data, and more flexible production techniques to improve their productivity in line with the new business model. By gathering and analysing vast volumes of data, analytics tools help companies to resource allocation and capital spends more effectively based on risk assessment. Finally, implications and directions for future research are discussed.

    Big data has emerged as the next technological revolution in IT industry after cloud computing and the Internet of Things. With the development of climate observing systems, particularly satellite meteorological observation and high-resolution climate models, and the rapid growth in the volume of climate data, climate prediction is now entering the era of big data. The application of big data will provide new ideas and methods for the continuous development of climate prediction. The rapid integration, cloud storage, cloud computing, and full-sample analysis of massive climate data makes it possible to understand climate states and their evolution more objectively, thus predicting the future climate more accurately. This paper describes the application status of big data in operational climate prediction in China; it analyzes the key big data technologies, discusses the future development of climate prediction operations from the perspective of big data, speculates on the prospects for applying climatic big data in cloud computing and data assimilation, and puts forward the notion of big data-based super-ensemble climate prediction methods and computerbased deep learning climate prediction methods.

    This paper presents the essential BigT design concepts and its lattice neutronic characteristics. Neutronic performance of a newly-proposed BA concept for PWR named BigT is investigated in this study. Preliminary lattice analyses of the BigT absorber-loaded WH 17x17 fuel assembly show a high potential of the concept as it performs relatively well in comparison with commercial burnable absorber technologies, especially in managing reactivity depletion and peaking factor. A sufficiently high control rod worth can still be obtained with the BigT absorbers in place. It is expected that with such performance and design flexibilities, any loading pattern and core management objective, including a soluble boron-free PWR, can potentially be fulfilled with the BigT absorbers. Future study involving full 3D reactor core simulations with the BigT absorbers shall hopefully verify this hypothesis. A new burnable absorber design for Pressurized Water Reactor (PWR) named 'Burnable absorber-Integrated control rod Guide Thimble' (BigT) was recently proposed. Unlike conventional burnable absorber (BA) technologies, the BigT integrates BA materials directly into the guide thimble but still allows insertion of control rod (CR). In addition, the BigT offers a variety of design flexibilities such that any loading pattern and core management objective can potentially be fulfilled.

The play with language and with associations, the foregrounding, in the short story, “Die verlossing van die beeld” (Breytenbach, 1983 with its metafictional title and apparently divergent motifs (rain/water, watch, onion, the death and burial of a grandfather acts, as it were, as an invitation to the reader to become a co-player. The reader ventures on a search for traces, intertextual links within the Breytenbach oeuvre and for already acknowledged influences such as Surrealism (which in turn casts some light on the strange title of the story and the Eastern philosophies such as Zen and the even older Taoism. The analysis also takes into account the context in which “Mouroir” was written, namely Breytenbach’s term in prison (1975-1982. Seeing that the writer had to hand in his manuscripts to the jail authorities regularly, he might have decided, consciously or by intuition, to hide some thoughts and feelings behind a screen or a mask, in, for example in “Die verlossing van die beeld”, a lighter tone and irony.

Dazu werden zunächst einige Aspekte des Konstrukts Wissensgesellschaft skizziert, das in seiner gegenwärtig populären Form ins Fahrwasser an volkswirtschaftlichen Verwertungskalkülen orientierter Denkformen geraten ist. Dies wird in Bezug auf die sich daran gekoppelte Programmatik von Kompetenz diskutiert, welche den «homo oeconomicus» beschwört und sich darin konträr zu klassisch bildungstheoretischen Kategorien verhält. Weitergeführt werden diese Überlegungen anhand der Problematisierung des Medienkompetenztheorems, das sich bis heute damit schwer tut, sich von der Vereinnahmung durch zweckrationale und restringierende Tendenzen zu befreien. Argumentiert wird, dass mit Medienkompetenz zu wenig einer milieuspezifischen Differenzierung Rechnung getragen werden kann, die eine wichtige Prämisse für eine soziale Ungleichheiten ernst nehmende Medienpädagogik ist. Als eine Alternative diskutieren wir, inwieweit sich hier praxeologische Perspektiven zum Verständnis jugendlichen Handelns anbieten.

  19. From big data to deep insight in developmental science.

    Gilmore, Rick O

    2016-01-01

    The use of the term 'big data' has grown substantially over the past several decades and is now widespread. In this review, I ask what makes data 'big' and what implications the size, density, or complexity of datasets have for the science of human development. A survey of existing datasets illustrates how existing large, complex, multilevel, and multimeasure data can reveal the complexities of developmental processes. At the same time, significant technical, policy, ethics, transparency, cultural, and conceptual issues associated with the use of big data must be addressed. Most big developmental science data are currently hard to find and cumbersome to access, the field lacks a culture of data sharing, and there is no consensus about who owns or should control research data. But, these barriers are dissolving. Developmental researchers are finding new ways to collect, manage, store, share, and enable others to reuse data. This promises a future in which big data can lead to deeper insights about some of the most profound questions in behavioral science.

  2. Characterization of a sagebrush (Artemisia tridentata ssp. wyomingensis) die-off on the Handford Site

    International Nuclear Information System (INIS)

    The Hanford Site contains one of the few remaining contiguous areas of shrub-steppe habitat left in Washington State. This habitat is home to many native plant and wildlife species, some of which are threatened with extinction or are unique to the Site. The importance of the Hanford Site increases as other lands surrounding the Site are developed, and these native species and habitats are lost. Stands of Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) on the Site are a particularly important component of shrub-steppe habitat, because a number of wildlife require big sagebrush for food and cover. Since 1993, researchers and field biologists have made anecdotal observations of dying and declining sagebrush in stands of shrubs near the 100 Areas. This study was initiated to delineate and document the general boundary where sagebrush stands appear to be declining. We mapped the areal extent of the die-off using a global positioning system and found that the central portion of the die-off encompasses 280 hectares. Shrub stand defoliation was estimated to be near or greater than 80% in this area. The remainder of the die-off area exhibits varying mixtures of completely defoliated, partially defoliated, and healthy-looking stands. Declining sagebrush stands comprise a total of 1776 hectares

    Radiation therapy is a first-line treatment option for localized prostate cancer and radiation-induced normal tissue damage are often the main limiting factor for modern radiotherapy regimens. Conversely, under-dosing of target volumes in an attempt to spare adjacent healthy tissues limits the likelihood of achieving local, long-term control. Thus, the ability to generate personalized data-driven risk profiles for radiotherapy outcomes would provide valuable prognostic information to help guide both clinicians and patients alike. Big data applied to radiation oncology promises to deliver better understanding of outcomes by harvesting and integrating heterogeneous data types, including patient-specific clinical parameters, treatment-related dose-volume metrics, and biological risk factors. When taken together, such variables make up the basis for a multi-dimensional space (the "RadoncSpace") in which the presented modeling techniques search in order to identify significant predictors. Herein, we review outcome modeling and big data-mining techniques for both tumor control and radiotherapy-induced normal tissue effects. We apply many of the presented modeling approaches onto a cohort of hypofractionated prostate cancer patients taking into account different data types and a large heterogeneous mix of physical and biological parameters. Cross-validation techniques are also reviewed for the refinement of the proposed framework architecture and checking individual model performance. We conclude by considering advanced modeling techniques that borrow concepts from big data analytics, such as machine learning and artificial intelligence, before discussing the potential future impact of systems radiobiology approaches.

    The study attempts to understand how dying from cancer is portrayed by five movies produced in Hollywood between 1993 and 2006. Based on the cultural studies and their post-structuralism version and supported by the notions of discourse and subjectivity, as proposed by philosopher Michel Foucault, we suggest one of the possible readings of the movie picture corpus. We assess how the movie picture discourse acts as a cultural pedagogy that produces ways of seeing dying with cancer: immortalizing the healthy body image, silencing death, taking care of the dead body and, finally, accepting death. Our proposal is intended to stimulate reflections that may contribute to care and education in nursing. PMID:25080714

    If tobacco multinationals had their way, China might more closely resemble a chimney. So what are the costs of a potentially smokier future in China? Aside from health costs, there could be economically (and educationally) severe ones, according to a new study published in Social Science & Medicine by a Yale professor. Dr. Hong Wang analyzed how the cost of smoking impacts China's critical economic strengths: human capital investment (defined by education and healthcare), risk-taking capacity (defined by...

  14. Killing, letting die and euthanasia.

    Science.gov (United States)

    Husak, D N

    1979-12-01

    Medical ethicists debate whether or not the moral assessment of cases of euthanasia should depend on whether the patient is 'killed' or 'allowed to die'. The usual presupposition is that a clear distinction between killing and letting die can be drawn so that this substantive question is not begged. I contend that the categorisation of cases of instances of killing rather than as instances of letting die depends in part on a prior moral assessment of the case. Hence is it trivially rather than substantively true that the distinction has moral significance. But even if a morally neutral (ie non-question begging) distinction could be drawn, its application to the euthanasia controversy is problematic. I illustrate the difficulties of employing this distinction to reach moral conclusions by critically discussing Philippa Foot's recent treatment of euthanasia. I conclude that even if an act of euthanasia is an instance of killing, and there exists a prima facie moral duty not to kill, and no more stringent duty overrides this duty, one still cannot determine such an act to be morally impermissible.

  15. Die Familie Treplin im Ersten Weltkrieg

    Mense, Anna

    2008-01-01

    In der Geschichtswissenschaft gilt der Erste Weltkrieg als die "Urkatastrophe des 20. Jahrhunderts" (Kennan). Er stand am Anfang einer Epoche gewaltiger Umwälzungen, die erst am Ende des 20. Jahrhunderts einer neuen Weltordnung Platz machen sollte, die allerdings noch immer instabil ist. Er bewirkte die Aufweichung der überkommenen bürgerlichen Sozialordnung Europas, beschleunigte den Niedergang des Bürgertums als führende gesellschaftliche Schicht, setzte neue politische Kräfte frei "einerse...

  16. Die Optimierung der Entsorgungslogistik von Industrieunternehmen

    OpenAIRE

    Heimsoth, Jörg

    2000-01-01

    Im Arbeitsgebiet der Entsorgungslogistik von Industrieunternehmen ist bislang erst sehr vereinzelt angestrebt worden, systematisch die vorhandenen Prozesse zu optimieren. Im Rahmen dieser Arbeit wurde zunächst die Ausgangssituation der Entsorgungslogistik untersucht und dargestellt, dass die vorhandene Behältertechnik in Bezug auf die geforderte durchgängige Kompatibilität entlang der Transportkette Industrieentsorgung Schwachstellen aufweist und deutlich gemacht, dass eine Kombination der Le...

    2000-01-01

    Im vorliegenden Aufsatz geht die Autorin der Frage nach, inwieweit sich im Familienrecht - wie dies im Obligationenrecht der Fall ist - eine gewisse Konsistenz und nachvollziebare juristische Argumentation finden lässt. Dafür wird, ausgehend vom Rechtsverständnis zu Beginn dieses Jahrhunderts, hintereinander die Entwicklung der Scheidungsgründe, des Unterhaltsrechts, des Güterrechts und des Vorsorgeausgleichs sowie des Kindesrechts betrachtet. Am Ende kommt die Autorin zum Schluss, dass von e...

    Der anhaltende Strukturwandel in der Landwirtschaft und die spezifische Problematik der Intensivtierhaltung werfen regionale Entwicklungs- und Planungsprobleme auf, die vor allem in Niedersachsen eine kontroverse Diskussion über den Einsatz steuernder Instrumente und die Rolle der Raumordnung und Bauleitplanung auslöste. Die LAG Nordwest der ARL nahm diese Diskussion zum Anlass, im Rahmen einer Arbeitgruppe praxisorientierte Handlungsempfehlungen für eine bessere Integration landwirtschaftlic...

  20. Dual of Big-bang and Big-crunch

    OpenAIRE

    Bak, Dongsu

    2006-01-01

    Starting from the Janus solution and its gauge theory dual, we obtain the dual gauge theory description of the cosmological solution by procedure of the double anaytic continuation. The coupling is driven either to zero or to infinity at the big-bang and big-crunch singularities, which are shown to be related by the S-duality symmetry. In the dual Yang-Mills theory description, these are non singular at all as the coupling goes to zero in the N=4 Super Yang-Mills theory. The cosmological sing...
