    Full Text Available Purpose – to deeply examine customers’ perception in terms of how the determinants of trust and perceived risk affect their intention to adopt mobile commerce.Design/methodology/approach – literature review, conceptual framework, modelling method, quantitative survey methodology (questionnaire instrument.Findings – the perception of risk in terms of privacy, m-payments, m-commerce legislation and quality of delivered products has negative effect in the intention to adopt mobile commerce, while the good online vendors’ reputation, enticing promises, good encryption security and transparency, reduce the effect of risk and increase the intention to use m-commerce. The availability of easy to understand and find policies have positive effect in the intention to use m-commerce. When customers feel free of risks and have high level of trust in the intention to use mobile commerce they actually adopt it.Research limitation/implications –this empirical research contributed to the theory by exploring which factors influence or deter the m-commerce adoption. However, the UTAUT model, simple random sampling method and case studies on how the online vendors perform towards this topic are worth-exploring by future researchers.Practical implications – the research results show that mobile technology manufacturers and developers should improve both software and wireless network security, online vendors should improve their online reputation, transparency, and mobile website navigation. Lawmakers should improve m-commerce legislation to better protect customers in case of dispute with online vendors.Originality/value – previous researchers have never focused solely and in-depth on the determinants of perceived risk and trust. Moreover, this object had never been examined in the Greek Population.Keywords: mobile commerce adoption, security concerns, trust, perceived risksResearch type: literature review, Conceptual paper, Research paper

  9. The impact of transaction trust on consumers' intentions to adopt m-commerce: a cross-cultural investigation.

    Science.gov (United States)

    Kao, Danny Tengti

    2009-04-01

    Mobile commerce (M-commerce) has been acknowledged as one of the most representative transaction types driving e-commerce worldwide; however, the potential security threats that keep consumers from M-commerce still confound the M-commerce industry. This research attempts to explore two questions: What are the dimensions of transaction trust that may significantly affect consumers' intentions to adopt M-commerce, and what are the cultural dimensions that may significantly moderate the impact of transaction trust on consumers' intentions to adopt M-commerce? A research framework based on the BATE model and Hofstede's cultural dimensions was established to identify how transaction trust and cultural value affect consumers' intentions to adopt M-commerce. Results revealed that transaction trust significantly affects consumers' intentions to adopt M-commerce. However, while uncertainty avoidance moderates the impacts of business trust and security on consumers' intentions of M-commerce adoption, both individualism/collectivism and long-term/short-term orientation moderate the relationship between security trust and consumers' intentions of M-commerce adoption.

  10. Privacy preserving, real-time and location secured biometrics for mCommerce authentication

    Science.gov (United States)

    Kuseler, Torben; Al-Assam, Hisham; Jassim, Sabah; Lami, Ihsan A.

    2011-06-01

    Secure wireless connectivity between mobile devices and financial/commercial establishments is mature, and so is the security of remote authentication for mCommerce. However, the current techniques are open for hacking, false misrepresentation, replay and other attacks. This is because of the lack of real-time and current-precise-location in the authentication process. This paper proposes a new technique that includes freshly-generated real-time personal biometric data of the client and present-position of the mobile device used by the client to perform the mCommerce so to form a real-time biometric representation to authenticate any remote transaction. A fresh GPS fix generates the "time and location" to stamp the biometric data freshly captured to produce a single, real-time biometric representation on the mobile device. A trusted Certification Authority (CA) acts as an independent authenticator of such client's claimed realtime location and his/her provided fresh biometric data. Thus eliminates the necessity of user enrolment with many mCommerce services and application providers. This CA can also "independently from the client" and "at that instant of time" collect the client's mobile device "time and location" from the cellular network operator so to compare with the received information, together with the client's stored biometric information. Finally, to preserve the client's location privacy and to eliminate the possibility of cross-application client tracking, this paper proposes shielding the real location of the mobile device used prior to submission to the CA or authenticators.

    Full Text Available Today, with the development in wireless and mobile technologies, Mobile Commerce (m-commerce is expected to make substantial impact on the business landscape. The mobile cellular market is the fastest growing telecommunication market in terms of subscriber numbers and popularity in India. Mobile Commerce market in India is expected to grow at a CAGR of 71.06 percent by the year 2016. The substantial increase of the mobile users is linked with greater adoption for mobile-commerce in India. At present, Indian users indulge in mobile purchases for low value transactions such as entertainment services, games, and music downloads. Mobile commerce is quite popular in the developed countries but in India it is in nascent stage and yet to take off. This study captures users’ acceptance behaviour towards M-commerce by applying theory of planned behaviour (TPB model developed by Ajzen (1991. Results indicate that attitude and perceived behavioural control have positive and significant impact on individual’s intention while subjective norm has a positive but not significant impact on intention. Further, intention is found to be significantly and positively related with behaviour.

  15. dLocAuth: a dynamic multifactor authentication scheme for mCommerce applications using independent location-based obfuscation

    Science.gov (United States)

    Kuseler, Torben; Lami, Ihsan A.

    2012-06-01

    This paper proposes a new technique to obfuscate an authentication-challenge program (named LocProg) using randomly generated data together with a client's current location in real-time. LocProg can be used to enable any handsetapplication on mobile-devices (e.g. mCommerce on Smartphones) that requires authentication with a remote authenticator (e.g. bank). The motivation of this novel technique is to a) enhance the security against replay attacks, which is currently based on using real-time nonce(s), and b) add a new security factor, which is location verified by two independent sources, to challenge / response methods for authentication. To assure a secure-live transaction, thus reducing the possibility of replay and other remote attacks, the authors have devised a novel technique to obtain the client's location from two independent sources of GPS on the client's side and the cellular network on authenticator's side. The algorithm of LocProg is based on obfuscating "random elements plus a client's data" with a location-based key, generated on the bank side. LocProg is then sent to the client and is designed so it will automatically integrate into the target application on the client's handset. The client can then de-obfuscate LocProg if s/he is within a certain range around the location calculated by the bank and if the correct personal data is supplied. LocProg also has features to protect against trial/error attacks. Analysis of LocAuth's security (trust, threat and system models) and trials based on a prototype implementation (on Android platform) prove the viability and novelty of LocAuth.

    2015-07-01

    We present an implementation of a method based on the Legendre transformation for reconstruction charged particle tracks in the central drift chamber of the Belle II experiment. The method is designed for fast track finding and restoring circular patterns of track hits in transverse plane. It is done by searching for common tangents to drift circles of hits in the conformal space. With known transverse trajectories longitudinal momentum estimation performed by assigning stereo hits followed by determination of the track parameters. The method includes algorithms responsible for track quality estimation and reduction of rate of fakes. The work is targeting at increasing the efficiency and reducing the execution time because the computing power available to the experiment is limited. The algorithm is developed within the Belle II software environment with using Monte-Carlo simulation for probing its efficiency.

    The aim of this article is to describe our experience in operating a capacity-building programme, the Korea International Cooperation Project, for global nursing leaders from developing countries, held during the International Council of Nurses (ICN) Conference in 2015 in Seoul, Korea. Globalization points to the importance of global leadership among nursing leaders. In accordance with the theme of 'Global Citizen, Global Nursing' at the ICN conference in 2015, a capacity-building programme for nursing leaders of developing countries was implemented. The global nursing leadership programme shared experiences during the preparation and operation of the conference. To prepare the programme, this paper describes selecting participants, working with invitation lists from 30 countries, and recruiting and training volunteers. The operation of the programme, orientation, organizing tailored programmes for participant groups, addressing unexpected issues and evaluating the programme are described. ICN could implement capacity-building programmes for nursing leaders of developing countries during its ICN conference for the nursing society. A programme tailored for each continent with similar sociocultural backgrounds and health issues would provide chances for collaboration and networking. A policy to compile global nursing indicators should be developed. This would allow nursing leaders to learn about the strengths and weaknesses of global nursing and provide evidence for collaboration. The programme was successful in introducing and broadening global perspectives of participants on health and education as well as building a network among leaders and next-generation leaders in participating countries for future cooperation and collaboration. © 2016 International Council of Nurses.

  9. Global engineering education programs: More than just international experiences

    Science.gov (United States)

    McNeill, Nathan J.

    Engineers in both industry and academia recognize the global nature of the profession. This has lead to calls for engineering students to develop knowledge, skills, and attitudes necessary for success within a global profession. Many institutions are developing globally oriented programs specifically for their engineering students and are eager to know if these programs are helping their students to develop attributes that meet their program objectives, accreditation requirements, and the needs and desires of prospective employers. Administrators of such programs currently lack research data to support the learning objectives they are setting for their programs. This study documented the individual experiences and learning outcomes of students involved in three global education programs for engineering students. The first program provided a portfolio of experiences including foreign language instruction, one semester of study abroad, internships in the U.S. and abroad, and a two-semester global team design project. The second program was a one semester study abroad program in China, and the third was a global service project whose purpose was to design an irrigation system for two small farms in Rwanda. The research questions guiding this study were: 1. What specific knowledge, skills, and attitudes are students gaining from participation in their respective global engineering programs? 2. What kinds of experiences are resulting in these learning outcomes? Interviews were used to elicit the experiences and learning outcomes of participants in this study. Program administrators were also interviewed for their perspectives on the experiences and learning outcomes of participants for the purpose of triangulation. The study identified more than 50 outcomes that resulted from students' experiences in these three programs. The most prevalent outcomes across all three programs included knowledge of culture, openness to new experiences and other cultures, and communication

  13. Speculative Fictions for Understanding Global Change Environments: Two Thought Experiments

    Directory of Open Access Journals (Sweden)

    Noel Gough

    2003-03-01

    Full Text Available The purpose of a thought experiment, as the term was used by quantum and relativity physicists in the early part of the twentieth century, was not prediction (as is the goal of classical experimental science, but more defensible representations of present ‘realities’. Speculative fictions, from Mary Shelley's Frankenstein to the Star Wars cinema saga, can be read as sociotechnical thought experiments that produce alternative representations of present circumstances and uncertainties, and anticipate and critique possible futures. In this essay I demonstrate how two examples of popular speculative fictions, Frank Herbert's Dune (1965 and Ursula Le Guin's The Telling (2000, function as thought experiments that problematise global transitions in their respective eras. I argue that critical readings of such stories can help us to anticipate, critique, and respond constructively to social and cultural changes and change environments within nation-states that constitute, and are constituted by, global change processes and their effects.

    A multi-method case study examined how the economic and political processes of globalization have influenced the determinants of health among low-income children in Saskatoon, Saskatchewan, Canada. This paper presents the results from the qualitative interview component of the case study. The purpose of the interviews was to uncover the lived experience of low-income families and their children in Saskatoon with regards to political and economic trends related to globalization, an important addition to the usual globalization and health research that relies primarily on cross-country regressions in which the personal impacts remain hidden. In-depth phenomenological interviews with 26 low-income parents of young children (aged zero to five) who were residents of Saskatoon. A combination of volunteer and criterion sampling was used. Interview questions were open-ended and based upon an analytical framework. Analysis proceeded through immersion in the data, a process of open coding, and finally through a process of selective coding. The larger case study and interviews indicate that globalization has largely not been benefiting low-income parents with young children. Low-income families with young children were struggling to survive, despite the tremendous economic growth occurring in Saskatchewan and Saskatoon at the time of the interviews. This often led to participants expressing a sense of helplessness, despair, isolation, and/or anger. Respondents' experiences suggest that globalization-related changes in social conditions and public policies and programs have great potential to negatively affect family health through either psychosocial effects in individuals and/or decreased levels of social cohesion in the community.

  15. Student objectives and learning experiences in a global health elective.

    International health electives offer unique experiences for medical students to develop clinical skills and cultural competencies in unique and diverse environments. Medical students have been increasingly pursuing these learning opportunities despite the challenges. However, their goals in pursuing these opportunities and the relation between their learning objectives and actual experiences have not been studied adequately. It is important to assess these programs based on student objectives and whether those objectives are met. Thirty-seven medical students from five cohorts at a US medical school completed pre-post questionnaires regarding their global health elective objectives and learning experiences. The questionnaires included mostly open-ended questions and a Likert-scale rating of their overall experience. Qualitative thematic analysis involved inductive coding and followed a content-driven immersion-crystallization approach. Quantitative program evaluation measures yielded descriptive statistics. Five general objectives and four types of learning experiences were identified. Student objectives were: (1) to observe the practice and organization of health care in another country; (2) improve medical/surgical skills; (3) improve language skills; (4) learn about another culture; and (5) deepen knowledge of infectious diseases. All of their objectives were achieved. Moreover, one learning theme, "self-reflection and personal growth," was not a student objective. Quantitative assessment showed that most students had a favorable elective experience. Program challenges were also identified. Students in a global health elective were able to fulfill self-identified learning objectives, while also gaining other unexpected yet important lessons. Students' learning objectives also should be considered in evaluating learning experiences in international health electives.

  16. Structural Design Feasibility Study for the Global Climate Experiment

    2008-12-01

    Neon, Inc. is proposing to establish a Global Change Experiment (GCE) Facility to increase our understanding of how ecological systems differ in their vulnerability to changes in climate and other relevant global change drivers, as well as provide the mechanistic basis for forecasting ecological change in the future. The experimental design was initially envisioned to consist of two complementary components; (A) a multi-factor experiment manipulating CO{sub 2}, temperature and water availability and (B) a water balance experiment. As the design analysis and cost estimates progressed, it became clear that (1) the technical difficulties of obtaining tight temperature control and maintaining elevated atmospheric carbon dioxide levels within an enclosure were greater than had been expected and (2) the envisioned study would not fit into the expected budget envelope if this was done in a partially or completely enclosed structure. After discussions between NEON management, the GCE science team, and Keith Lewin, NEON, Inc. requested Keith Lewin to expand the scope of this design study to include open-field exposure systems. In order to develop the GCE design to the point where it can be presented within a proposal for funding, a feasibility study of climate manipulation structures must be conducted to determine design approaches and rough cost estimates, and to identify advantages and disadvantages of these approaches including the associated experimental artifacts. NEON, Inc requested this design study in order to develop concepts for the climate manipulation structures to support the NEON Global Climate Experiment. This study summarizes the design concepts considered for constructing and operating the GCE Facility and their associated construction, maintenance and operations costs. Comparisons and comments about experimental artifacts, construction challenges and operational uncertainties are provided to assist in selecting the final facility design. The overall goal

  17. A methodology for global validation of microarray experiments

    Sladek Robert

    2006-07-01

    Full Text Available Abstract Background DNA microarrays are popular tools for measuring gene expression of biological samples. This ever increasing popularity is ensuring that a large number of microarray studies are conducted, many of which with data publicly available for mining by other investigators. Under most circumstances, validation of differential expression of genes is performed on a gene to gene basis. Thus, it is not possible to generalize validation results to the remaining majority of non-validated genes or to evaluate the overall quality of these studies. Results We present an approach for the global validation of DNA microarray experiments that will allow researchers to evaluate the general quality of their experiment and to extrapolate validation results of a subset of genes to the remaining non-validated genes. We illustrate why the popular strategy of selecting only the most differentially expressed genes for validation generally fails as a global validation strategy and propose random-stratified sampling as a better gene selection method. We also illustrate shortcomings of often-used validation indices such as overlap of significant effects and the correlation coefficient and recommend the concordance correlation coefficient (CCC as an alternative. Conclusion We provide recommendations that will enhance validity checks of microarray experiments while minimizing the need to run a large number of labour-intensive individual validation assays.

    2017-04-01

    Droughts caused water shortages could lead to serious consequences on the socioeconomic and environmental well-being. In the context of changing climate, droughts monitoring, attributions and impact assessments have been performed using observations (e.g., Sun et al., 2012; Zhang et al., 2016) and climate model projections (e.g., Liu et al., 2016, 2017); with expectation that such scientific knowledge would feed into long-term adaptation and mitigation plans to tackle potentially unfavorable future drought impacts in a warming world. Inspired by the 2015 Paris Agreement, the HAPPI (Half a degree Additional warming, Projections, Prognosis and Impacts) experiments were set up to better inform international policymakers about the socioeconomic and environmental impacts under less severe global warming conditions. This study aims to understand the potential shift in meteorological droughts from the past into the future on a global scale. Based on the HAPPI data, we evaluate the change in drought related indices (i.e., PET/P, PDSI) from the past to the future scenarios (1.5 and 2 degrees Celsius warming). Here we present some early results (MIROC5 as demonstration) on identified hotspots and discuss the differences in severity of droughts between these warming worlds and associated consequences.

    We experimentally analyze collective dynamics of a population of 20 electronic Wien-bridge limit-cycle oscillators with a linear or nonlinear phase-shifting unit in the global feedback loop. With linear unit we observe, with increase of the coupling strength, a standard Kuramoto-like transition to a fully synchronous state; the threshold of the transition depends on the phase shift. In case of nonlinear global coupling we first observe a transition to a state when approximately half of the population forms a synchronous cluster. With further increase of the coupling strength we observe destruction of this cluster and formation of a self-organized quasiperiodic state, predicted in [M. Rosenblum and A. Pikovsky, PRL, 98, 064101 (2007)]. In this state, frequencies of all oscillators are smaller than the frequency of the mean field, so that the oscillators are not locked to the mean field they create and their dynamics is quasiperiodic. The transition is characterized by a non-monotonic dependence of the order parameter on the coupling strength. We demonstrate a good correspondence between theory and experiment.

  4. Perception of global facial geometry is modulated through experience

    2015-03-01

    Full Text Available Identification of personally familiar faces is highly efficient across various viewing conditions. While the presence of robust facial representations stored in memory is considered to aid this process, the mechanisms underlying invariant identification remain unclear. Two experiments tested the hypothesis that facial representations stored in memory are associated with differential perceptual processing of the overall facial geometry. Subjects who were personally familiar or unfamiliar with the identities presented discriminated between stimuli whose overall facial geometry had been manipulated to maintain or alter the original facial configuration (see Barton, Zhao & Keenan, 2003. The results demonstrate that familiarity gives rise to more efficient processing of global facial geometry, and are interpreted in terms of increased holistic processing of facial information that is maintained across viewing distances.

    A general geometry gyro-kinetic model for particle simulation of plasma turbulence in tokamak experiments is described. It incorporates the comprehensive influence of noncircular cross section, realistic plasma profiles, plasma rotation, neoclassical (equilibrium) electric fields, and Coulomb collisions. An interesting result of global turbulence development in a shaped tokamak plasma is presented with regard to nonlinear turbulence spreading into the linearly stable region. The mutual interaction between turbulence and zonal flows in collisionless plasmas is studied with a focus on identifying possible nonlinear saturation mechanisms for zonal flows. A bursting temporal behavior with a period longer than the geodesic acoustic oscillation period is observed even in a collisionless system. Our simulation results suggest that the zonal flows can drive turbulence. However, this process is too weak to be an effective zonal flow saturation mechanism.

    Students at Chicago State University and Sonoma State University have undertaken observational programs using telescopes of the Global Telescope Network (GTN) and SkyNet. The GTN is a network of small telescopes funded by GLAST to support the science of high energy astrophysics missions, specifically GLAST, Swift and XMM-Newton. It is managed by the NASA E/PO Group at Sonoma State University. SkyNet encompasses a network  of small telescopes managed from the University of North Carolina to catch gamma ray burst afterglows. A primary motivator behind both networks is education. In the program outlined here, undergraduate students will schedule, reduce and analyze observations of active galaxies and other targets. Students will then present their work as part of observational course work, or in some cases as a "capstone” research experience required for graduation. This work will give the students direct experience with several aspects of scientific research, including literature searches, data acquisition and analysis, and reporting of results.

    We experimentally analyze collective dynamics of a population of 20 electronic Wien-bridge limit-cycle oscillators with a nonlinear phase-shifting unit in the global feedback loop. With an increase in the coupling strength we first observe formation and then destruction of a synchronous cluster, so that the dependence of the order parameter on the coupling strength is not monotonic. After destruction of the cluster the ensemble remains nevertheless coherent, i.e., it exhibits an oscillatory collective mode (mean field). We show that the system is now in a self-organized quasiperiodic state, predicted in Rosenblum and Pikovsky [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.98.064101 98, 064101 (2007)]. In this state, frequencies of all oscillators are smaller than the frequency of the mean field, so that the oscillators are not locked to the mean field they create and their dynamics is quasiperiodic. Without a nonlinear phase-shifting unit, the system exhibits a standard Kuramoto-like transition to a fully synchronous state. We demonstrate a good correspondence between the experiment and previously developed theory. We also propose a simple measure which characterizes the macroscopic incoherence-coherence transition in a finite-size ensemble.

Most subsystem specific trigger processor boards were replaced with powerful general purpose processor boards, conforming to the MicroTCA standard, whose tasks are performed by firmware on an FPGA of the Xilinx Virtex 7 family. Furthermore, the muon trigger system moved from a subsystem centered approach, where each of the three muon detector systems provides muon candidates to the Global Muon Trigger (GMT), to a region based system, where muon track finders (TFs) combine information from the subsystems to generate muon candidates in three detector regions, that are then sent to the upgraded GMT. The upgraded GMT receives up to 108 muons from the processors of the muon TFs in the barrel, overlap, and endcap detector regions. The muons are...

    Transport extracorporeal membrane oxygenation (ECMO) is currently available at 12 centers. We report a 22-year experience from the only facility providing global transport ECMO. Indications for transport ECMO include lack of ECMO services, inability to transport conventionally, inability to wean from cardiopulmonary bypass, extracorporeal cardiopulmonary resuscitation, and need to move a patient on ECMO for specialized services such as organ transplantation. Retrospective database review of children undergoing inhouse and transport ECMO from 1985 to 2007. Sixty-eight children underwent transport ECMO. Fifty-six were transported on ECMO into our facility. The remaining 12 were moved between 2 outside locations. Ground vehicles and fixed-wing aircraft were used. Distance transported was 8 to 7500 miles (13-12070 km), mean 1380 miles (2220 km). There were 116 inhouse ECMO runs. No child died during transport. Survival to discharge after transport ECMO was 65% (44/68) and, for inhouse ECMO, was 70% (81/116). Transport ECMO is feasible and effective, with survival rates comparable to inhouse ECMO. We have used transport ECMO to help children at non-ECMO centers with pulmonary failure who have not improved with inhaled nitric oxide and high-frequency ventilation. We have also transported a child after extracorporeal cardiopulmonary resuscitation, which may represent an emerging indication for transport ECMO. Transport ECMO often is the only option for children too unstable for conventional transport or those already on ECMO and requiring a specialized service at another facility, such as organ transplantation.

    Full Text Available Globalization is a trend that impacts everyone more and more each day. For centuries, globalization has progressively knitted together the world and created unity out of great diversity. This is a discourse on political economy of globalization and its implication for Africa with particular reference to Nigeria. This study investigates the political economy of globalization in the development process in Nigeria. It examines the impact of globalization on industrialization and the attendant problems of globalization on the Nigerian economy. In light of our findings, we recommend that Nigeria should adopt appropriate policies and strategies similar to other developed countries to compete in the international capitalist system in which we are now an integrated part.

    Full Text Available Issue of global poverty became very worrisome that the United Nations Millennium Summit in 2000 placed it at the heart of global agenda to halve 1990 extreme poverty and hunger rates by the end of 2015. This means that the percentage of improvised people defined by the World Bank as those living on less than $1.25 a day must fall to 25 percent by the end of this year, while the proportion of people without adequate food security must be reduced to 12.5 percent. To achieve the aim, global leaders agreed to set a time-bound and measurable goals and targets. The United Nations believes that achieving the target which involves improvements in standards of living, universal primary education, empowerment of women, reduction in mortality rates, unemployment, among others, requires a global partnership with national governments, multinational agencies through global governance architecture. The ideal of global governance is a process of co-operative leadership that brings together national governments, multilateral public agencies and civil society to achieve commonly accepted goals. It provides strategic direction and then marshals collective energies to address global challenges. It is inclusive, dynamic and operates across national and sectoral boundaries and interests. It is this perspective of global governance that drives the Millennium Development Goals agenda toward global poverty reduction. This perspective is making positive contributions with some regions in the world heading toward the achievement of the target. Even those countries in sub-saharan Africa where most of the global poor live and who are lagging behind, are making frantic efforts to do so, with the assistance of global bodies like the world bank,  IMF, UNIDO, among others. The beauty of global governance is that it appears to be more democratic than authoritarian, more openly political than bureaucratic, and more integrated than specialized. This is the level that drives the

    2016-05-01

    The preparation of future baccalaureate-prepared nurses will require undergraduate students to have both cultural awareness and global or international health competencies in order to meet the increasingly complex health care needs of a diverse community. Additionally, the nursing accrediting bodies have identified global healthcare as an area of core knowledge for clinical nurses. In order to meet the workforce needs, and provide global education of the undergraduate student body, we designed an international clinical experience within the undergraduate Community/Population Health course. The purpose of this article is to provide a guide for faculty in the planning, infrastructure needs, and implementation of a global clinical experience for undergraduate nursing students, in the context of the United States with addressing university concerns for student safety and security while abroad.

  20. The Role of Musical Experience in Hemispheric Lateralization of Global and Local Auditory Processing.

    Science.gov (United States)

    Black, Emily; Stevenson, Jennifer L; Bish, Joel P

    2017-08-01

    The global precedence effect is a phenomenon in which global aspects of visual and auditory stimuli are processed before local aspects. Individuals with musical experience perform better on all aspects of auditory tasks compared with individuals with less musical experience. The hemispheric lateralization of this auditory processing is less well-defined. The present study aimed to replicate the global precedence effect with auditory stimuli and to explore the lateralization of global and local auditory processing in individuals with differing levels of musical experience. A total of 38 college students completed an auditory-directed attention task while electroencephalography was recorded. Individuals with low musical experience responded significantly faster and more accurately in global trials than in local trials regardless of condition, and significantly faster and more accurately when pitches traveled in the same direction (compatible condition) than when pitches traveled in two different directions (incompatible condition) consistent with a global precedence effect. In contrast, individuals with high musical experience showed less of a global precedence effect with regards to accuracy, but not in terms of reaction time, suggesting an increased ability to overcome global bias. Further, a difference in P300 latency between hemispheres was observed. These findings provide a preliminary neurological framework for auditory processing of individuals with differing degrees of musical experience.

    The paper discusses the impact of environmental problems on the world's geothermal generating stations. The significant impacts include conflicts in land use, air pollution, subsidence, water pollution, induced seismicity, blowouts, and noise. Development of geothermal resources has been slowed down in some countries: in U.S., the emission of hydrogen sulfide produced a problem; in Japan, land use in national parks and waste-water disposal resulted in difficulties; and in El Salvador, waste-water disposal presented a difficulty. Geothermal development faces many regulations and difficulties, particularly in U.S., a country which could stimulate a global acceleration in this field with appropriately relaxed controls.

    O'Gorman, Eoin J

    2014-05-01

    There is a growing appreciation for the importance of non-consumptive effects in predator-prey interaction research, which can often outweigh the importance of direct feeding. Barrios-O'Neill et al. (2014) report a novel method to characterize such effects by comparing the functional response of native and introduced intermediate consumers in the presence and absence of a higher predator. The invader exhibited stronger direct feeding and was also more resistant to intimidation by the higher predator. This experimental framework may be incorporated into mainstream global change research, for example, to quantify the importance of non-consumptive effects for the success or failure of biological invasions.

  6. Selection between foreground models for global 21-cm experiments

    CERN Document Server

    Harker, Geraint

    2015-01-01

    The precise form of the foregrounds for sky-averaged measurements of the 21-cm line during and before the epoch of reionization is unknown. We suggest that the level of complexity in the foreground models used to fit global 21-cm data should be driven by the data, under a Bayesian model selection methodology. A first test of this approach is carried out by applying nested sampling to simplified models of global 21-cm data to compute the Bayesian evidence for the models. If the foregrounds are assumed to be polynomials of order n in log-log space, we can infer the necessity to use n=4 rather than n=3 with <2h of integration with limited frequency coverage, for reasonable values of the n=4 coefficient. Using a higher-order polynomial does not necessarily prevent a significant detection of the 21-cm signal. Even for n=8, we can obtain very strong evidence distinguishing a reasonable model for the signal from a null model with 128h of integration. More subtle features of the signal may, however, be lost if the...

  7. Relation of tolerance of ambiguity to global and specific paranormal experience.

    Science.gov (United States)

    Houran, J; Williams, C

    1998-12-01

    We examined the relationship of tolerance of ambiguity to severe global factors and specific types of anomalous or paranormal experience. 107 undergraduate students completed MacDonald's 1970 AT-20 and the Anomalous Experiences Inventory of Kumar, Pekala, and Gallagher. Scores on the five subscales of the Anomalous Experiences Inventory correlated differently with tolerance of ambiguity. Global paranormal beliefs, abilities, experiences, and drug use were positively associated with tolerance of ambiguity, whereas a fear of paranormal experience showed a negative relation. The specific types of anomalous experiences that correlated with tolerance of ambiguity often involved internal or physiological experience, e.g., precognitive dreams, memories of reincarnation, visual apparitions, and vestibular alterations. We generally found no effects of age of sex. These results are consistent with the idea that some paranormal experiences are misattributions of internal experience to external ('paranormal') sources, a process analogous to mechanisms underpinning delusions and hallucinations.

    2013-01-31

    The Dalla Lana School of Public Health uses an "add-on" or concentration model of global health education. Records of masters' graduate cohorts across five disciplinary fields from 2006 to 2009 were classified as to prior experience at application and completion of global health concentration requirements. Alumni from the first two cohorts (2006-08 and 2007-09) were interviewed using a semi-structured interview guide. Prior experience was not linked consistently with the number of elective courses, location of practica or completion of requirements. Successful completion of the global health requirements depended more on the student's base disciplinary program. Interviewed alumni with medium prior experience reported greater satisfaction with the concentration. Alumni with lower prior experience wanted more courses and support with practica. The pros and cons of a concentration model of global public health graduate education are discussed.

    Systematic triangulation may address common challenges in evaluation, such as the scarcity or unreliability of data, or the complexities of comparing and cross-checking evidence from diverse disciplines. Used to identify key evaluation findings, its application has proven to be effective in addressing the limitations encountered in country-level evaluation analysis conducted by the Independent Evaluation Office of the Global Environment Facility (GEF). These include the scarcity or unreliability of national statistics on environmental indicators and data series, especially in Least Developed Countries; challenges in evaluating the impacts of GEF projects; and inherent difficulties in defining the GEF portfolio of projects prior to the undertaking of the evaluation. In addition to responding to the need for further developing triangulation protocols, procedures and/or methodologies advocated by some authors, the approach offers a contribution to evaluation practice. This applies particularly to those evaluation units tasked with country-level evaluations in international organizations, facing similar constraints.

    The udergraduate program of Geophysical Engineering at the School of Engineering, of the Univesidad Nacional Autónoma de México (UNAM), went through an update process that concluded in 2006. As part of the program, the student takes three geophysical prospecting courses (gravity and magnetics, electric, electromagnetics, and seismic methods). The older program required a three-week field experience for each course in order to gradute. The new program considers only one extended field experience. This work stresses the importance of international academic exchange, where undergraduate students could participate, such as the Summer of Applied Geophysical Experience (SAGE), and interaction with research programs, such as the MesoAmerican Subduction Experiment (MASE). Also, we propose a scheeme for this activity based on those examples; both of them have in common real geophysical problems, from which students could benefit. Our proposal covers academic and logistic aspects to be taken into account, enhancing the relevance of interaction between other academic institutions, industry, and UNAM, in order to obtain a broader view of geophysics.

    2016-09-14

    The Compact Muon Solenoid (CMS) experiment is one of two general purpose detectors at the Large Hadron Collider (LHC) at the particle physics research laboratory in Geneva (CERN). As such it allows a broad array of physics analyses from precision measurements of the standard model of particle physics to searches for exotic new particles. A series of upgrades and maintenance procedures took place in the first shut down from 2013 to 2015. The aim was to prepare the LHC for the collision energy of 13 TeV and further increase its luminosity. During this shut down also upgrades of the CMS experiment were installed.Due to the high rate of collisions at the LHC, it is impossible to record all such events. In order to reduce the event rate to a manageable level, a trigger system is deployed that selects interesting events. At the CMS experiment this system is divided into two levels: A first hardware based system that is optimised for speed and a second that is software based and applies more time consuming and preci...

    There has been increasing recognition of the disparities in surgical care throughout the world. Increasingly, efforts are being made to improve local infrastructure and training of surgeons in low-income settings. The purpose of this study was to review the first 5-years of a global academic pediatric general surgery partnership between UCLA and the Eduardo Mondlane University in Maputo, Mozambique. A mixed-methods approach was utilized to perform an ongoing needs assessment. A retrospective review of admission and operative logbooks was performed. Partnership activities were summarized. The needs assessment identified several challenges including limited operative time, personnel, equipment, and resources. Review of logbooks identified a high frequency of burn admissions and colorectal procedures. Partnership activities focused on providing educational resources, on-site proctoring, training opportunities, and research collaboration. This study highlights the spectrum of disease and operative case volume of a referral center for general pediatric surgery in sub-Saharan Africa, and it provides a context for academic partnership activities to facilitate training and improve the quality of pediatric general surgical care in limited-resource settings.

  16. Experiments on the global instability of confined axisymmetric dense wakes.

    Science.gov (United States)

    Li, Larry; Juniper, Matthew

    2007-11-01

    Recent theoretical studies [M. Juniper, J. Fluid Mech. 565, 171-195 (2006); M. Juniper and S. Candel, J. Fluid Mech. 482, 257-269 (2003)] predict that confinement increases the hydrodynamic instability of wakes by causing the transition from convective to absolute instability to occur at lower values of shear. Experimental evidence supporting this prediction is presented here for a confined, axisymmetric wake at density ratios, S ≡ ρ1 /ρ2> 1 (i.e. dense wake). The wake was produced by a pair of convergent nozzles mounted concentrically, one within the other, in a low-turbulence wind tunnel facility. Variations in S were achieved by employing two high density gases (S = 1.53 and 5.11) in the inner flow with air in the outer flow. For a fixed S, there existed a critical value of shear above which dominant peaks appeared abruptly in the near-wake velocity spectra, as quantified by hot-wire anemometry. Corresponding high-speed video sequences revealed large-scale, sinuous wake motions. Results on the confined wake's response to externally-applied, acoustic forcing are also presented. The presence of discrete spectral peaks and coordinated instability oscillations suggests the emergence of a self-sustained, global mode.

  20. A global high-resolution model experiment on the predictability of the atmosphere

    Science.gov (United States)

    Judt, F.

    2016-12-01

    Forecasting high-impact weather phenomena is one of the most important aspects of numerical weather prediction (NWP). Over the last couple of years, a tremendous increase in computing power has facilitated the advent of global convection-resolving NWP models, which allow for the seamless prediction of weather from local to planetary scales. Unfortunately, the predictability of specific meteorological phenomena in these models is not very well known. This raises questions about which forecast problems are potentially tractable, and what is the value of global convection-resolving model predictions for the end user. To address this issue, we use the Yellowstone supercomputer to conduct a global high-resolution predictability experiment with the recently developed Model for Prediction Across Scales (MPAS). The computing power of Yellowstone enables the model to run at a globally uniform resolution of 4 km with 55 vertical levels (>2 billion grid cells). These simulations, which require 3 million core-hours for the entire experiment, allow for the explicit treatment of organized deep moist convection (i.e., thunderstorm systems). Resolving organized deep moist convection alleviates grave limitations of previous predictability studies, which either used high-resolution limited-area models or global simulations with coarser grids and cumulus parameterization. By computing the error growth characteristics in a set of "identical twin" model runs, the experiment will clarify the intrinsic predictability limits of atmospheric phenomena on a wide range of scales, from severe thunderstorms to global-scale wind patterns that affect the distribution of tropical rainfall. Although a major task by itself, this study is intended to be exploratory work for a future predictability experiment going beyond of what has so far been feasible. We hope to use CISL's new Cheyenne supercomputer to conduct a similar predictability experiments on a global mesh with 1-2 km resolution. This

    2017-01-01

    One of the most important aspects of data processing at LHC experiments is the particle identification (PID) algorithm. In LHCb, several different sub-detector systems provide PID information: the Ring Imaging CHerenkov (RICH) detector, the hadronic and electromagnetic calorimeters, and the muon chambers. To improve charged particle identification, several neural networks including a deep architecture and gradient boosting have been applied to data. These new approaches provide higher identification efficiencies than existing implementations for all charged particle types. It is also necessary to achieve a flat dependency between efficiencies and spectator variables such as particle momentum, in order to reduce systematic uncertainties during later stages of data analysis. For this purpose, "flat” algorithms that guarantee the flatness property for efficiencies have also been developed. This talk presents this new approach based on machine learning and its performance.

    Discrimination and unequal treatment faced by migrant nurses is one of the most important issues related to international migration of nurses. This article present a discussion of the broad topics surrounding nurse migration followed by a synthesis of 15 published qualitative and quantitative research articles related to specifically to the subject of employment discrimination experiences of internationally educated nurses in Canada, United Kingdom and the United States. Evidence shows that international nurses often encounter covert and overt discrimination in the workplace. It is important for nurses to be aware of the extent and nature of employment discrimination encountered by migrant nurses. Nursing leaders and policy makers need to ensure that all nurses are treated equally in the workplace.

    Full Text Available By combining the wireless network and E-commerce, suppliers can provide a more convenient and quicker service on a human scale for their customers. The main advantages of such services are their high availability, independence of physical location and time. Mobile commerce raises a number of security and privacy challenges. However, security has always been the key issue for the development of mobile E-commerce, which is more vulnerable than the traditional E-commerce mode. . In order to solve the problem of security gap in the transmission of mobile E-commerce information, a framework based on J2ME/MIDP is proposed, which combines double layer encryption schemes, stego-image and secure XML messages which transferred between the mobile terminal and the server. Our method provide strong secure and invisible communication with high security and high operating efficiency that compatible with many types of mobile terminal.

    This paper mainly talks about the currently hot topic-globalization. Firstly, it brings out the general trend about globalization and how to better understand its implication. Secondly, it largely focuses on how to deal with it properly, especially for international marketers. Then, facing with the overwhelming trend, it is time for us to think about seriously what has globalization brought to us. Last but not least, it summarized the author's personal view about the future of globalization and how should we go.

    2014-09-01

    To respond to the challenge of how organizations can develop leaders who can think strategically, we investigate the relation of leaders' global work experiences--that is, those experiences that require the role incumbent to transcend national boundaries--to their competency in strategic thinking. We further examine whether leaders' exposure to a country whose culture is quite distinct from the culture of their own country (i.e., one that is culturally distant) moderates these relationships. Our analyses of 231 upper level leaders reveals that the time they have spent in global work experiences positively relates to their strategic thinking competency, particularly for leaders who have had exposure to a more culturally distant country. We discuss these findings in light of the research on international work experiences and leader development.

  11. Inequality measures perform differently in global and local assessments: An exploratory computational experiment

    2015-11-01

    Inequality measures are widely used in both the academia and public media to help us understand how incomes and wealth are distributed. They can be used to assess the distribution of a whole society-global inequality-as well as inequality of actors' referent networks-local inequality. How different is local inequality from global inequality? Formalizing the structure of reference groups as a network, the paper conducted a computational experiment to see how the structure of complex networks influences the difference between global and local inequality assessed by a selection of inequality measures. It was found that local inequality tends to be higher than global inequality when population size is large; network is dense and heterophilously assorted, and income distribution is less dispersed. The implications of the simulation findings are discussed.

    2016-01-01

    The scale-up of antiretroviral therapy (ART) in Malawi was based on a public health approach adapted to its resource-poor setting, with principles and practices borrowed from the successful tuberculosis control framework. From 2004 to 2015, the number of new patients started on ART increased from about 3000 to over 820,000. Despite being a small country, Malawi has made a significant contribution to the 15 million people globally on ART and has also contributed policy and service delivery innovations that have supported international guidelines and scale up in other countries. The first set of global guidelines for scaling up ART released by the World Health Organization (WHO) in 2002 focused on providing clinical guidance. In Malawi, the ART guidelines adopted from the outset a more operational and programmatic approach with recommendations on health systems and services that were needed to deliver HIV treatment to affected populations. Seven years after the start of national scale-up, Malawi launched a new strategy offering all HIV-infected pregnant women lifelong ART regardless of the CD4-cell count, named Option B+. This strategy was subsequently incorporated into a WHO programmatic guide in 2012 and WHO ART guidelines in 2013, and has since then been adopted by the majority of countries worldwide. In conclusion, the Malawi experience of ART scale-up has become a blueprint for a public health response to HIV and has informed international efforts to end the AIDS epidemic by 2030.

    The area of forest plantations is increasing worldwide helping to meet timber demand and protect natural forests. However, with global change, monospecific plantations are increasingly vulnerable to abiotic and biotic disturbances. As an adaption measure we need to move to plantations that are more diverse in genotypes, species, and structure, with a design underpinned by science. TreeDivNet, a global network of tree diversity experiments, responds to this need by assessing the advantages and disadvantages of mixed species plantations. The network currently consists of 18 experiments, distributed over 36 sites and five ecoregions. With plantations 1-15 years old, TreeDivNet can already provide relevant data for forest policy and management. In this paper, we highlight some early results on the carbon sequestration and pest resistance potential of more diverse plantations. Finally, suggestions are made for new, innovative experiments in understudied regions to complement the existing network.

    Increasing concentrations of greenhouse gases in the atmosphere are expected to modify the global water cycle with significant consequences for terrestrial hydrology. We assess the impact of climate change on hydrological droughts in a multimodel experiment including seven global impact models (GIMs) driven by bias-corrected climate from five global climate models under four representative concentration pathways (RCPs). Drought severity is defined as the fraction of land under drought conditions. Results show a likely increase in the global severity of hydrological drought at the end of the 21st century, with systematically greater increases for RCPs describing stronger radiative forcings. Under RCP8.5, droughts exceeding 40% of analyzed land area are projected by nearly half of the simulations. This increase in drought severity has a strong signal-to-noise ratio at the global scale, and Southern Europe, the Middle East, the Southeast United States, Chile, and South West Australia are identified as possible hotspots for future water security issues. The uncertainty due to GIMs is greater than that from global climate models, particularly if including a GIM that accounts for the dynamic response of plants to CO2 and climate, as this model simulates little or no increase in drought frequency. Our study demonstrates that different representations of terrestrial water-cycle processes in GIMs are responsible for a much larger uncertainty in the response of hydrological drought to climate change than previously thought. When assessing the impact of climate change on hydrology, it is therefore critical to consider a diverse range of GIMs to better capture the uncertainty.

    BepiColombo is a joint ESA/JAXA mission to Mercury with challenging objectives regarding geophysics, geodesy and fundamental physics. In particular, the Mercury Orbiter Radio science Experiment (MORE) intends, as one of its goals, to perform a test of General Relativity. This can be done by measuring and constraining the parametrized post-Newtonian (PPN) parameters to an accuracy significantly better than current one. In this work we perform a global numerical full-cycle simulation of the BepiColombo Radio Science Experiments (RSE) in a realistic scenario, focussing on the relativity experiment, solving simultaneously for all the parameters of interest for RSE in a global least squares fit within a constrained multiarc strategy. The results on the achievable accuracy for each PPN parameter will be presented and discussed, confirming the significant improvement to the actual knowledge of gravitation theory expected for the MORE relativity experiment. In particular, we will show that, including realistic systematic effects in the range observables, an accuracy of the order of 10-6 can still be achieved in the Eddington parameter β and in the parameter α1, which accounts for preferred frame effects, while the only poorly determined parameter turns out to be ζ, which describes the temporal variations of the gravitational constant and the Sun mass.

    2014-01-01

    A theoretical analysis is presented to show the general occurrence of phase clusters in weakly, globally coupled oscillators close to a Hopf bifurcation. Through a reductive perturbation method, we derive the amplitude equation with a higher order correction term valid near a Hopf bifurcation point. This amplitude equation allows us to calculate analytically the phase coupling function from given limit-cycle oscillator models. Moreover, using the phase coupling function, the stability of phase clusters can be analyzed. We demonstrate our theory with the Brusselator model. Experiments are carried out to confirm the presence of phase clusters close to Hopf bifurcations with electrochemical oscillators.

    Wet tropospheric path delay can be a major error source for Global Positioning System (GPS) geodetic experiments. Strategies for minimizing this error are investigted using data from CASA Uno, the first major GPS experiment in Central and South America, where wet path delays may be both high and variable. Wet path delay calibration using water vapor radiometers (WVRs) and residual delay estimation is compared with strategies where the entire wet path delay is estimated stochastically without prior calibration, using data from a 270-km test baseline in Costa Rica. Both approaches yield centimeter-level baseline repeatability and similar tropospheric estimates, suggesting that WVR calibration is not critical for obtaining high precision results with GPS in the CASA region.

    Fundamental to improving the understanding of the total Earth system are increased and improved observations. In the coming decade several spaceborne instrumented platforms will be constructed and implemented. These platforms will, in large, be housing the NASA Earth Observing System (EOS) instrument suite. One of the proposed instruments is a wind profiling system which is currently referred to as the Laser Atmospheric Wind Sounder (LAWS). This instrument will use a CO2 Doppler lidar wind profiler to give wind measurements with a vertical and horizontal resolution which has yet to be seen globally. The LAWS instrument is now a candidate for launch on a NASA EOS-B platform and is fundamental to increasing our understanding of Earth system science. The LAWS data sets will form an integral component of the temporally continuous data base needed for research of the coupled climate systems. This instrument's observations will aid in giving an improved description of the atmospheric circulation, including the transports of energy, momentum, moisture, trace gases, and aerosols. Also, the wind data will be assimilated and used as the initial state for many global forecast models at various operational centers. Results of system simulation experiments are discussed, and future experiments are described.

    Short-term, study-abroad, elective engineering courses were developed in order to raise the international awareness and global competency of engineering students. These Compact International Experience (CIE) courses were taught in response to a strong student desire for engineering study abroad courses and an effort by the home institution to internationalize its curriculum. An assessment of repeat offerings of two three-semester-unit courses on Topics in Fluid Mechanics and Advanced Electronic Circuit Design in a three-week time frame in France and Australia was performed. The goals of the two CIE courses are an effective teaching of their respective technical content as well as a student understanding of the cultural environment and the impact of engineering solutions from a global and societal viewpoint. In the repeat offerings, increased interaction with local industry was an additional goal. The CIE courses were assessed through surveys completed at the beginning and end of the courses, weekly student reflection papers, course evaluations, and formalized instructor observations. Based on the assessment performed, the two CIE courses have been found to be a valuable approach in the delivery of engineering technical electives combined with an international experience.

    Full Text Available Abstract Background Climate change is a global public health problem that will require complex thinking if meaningful and effective solutions are to be achieved. In this conceptual paper we argue that GPs have much to bring to the issue of climate change from their wide-ranging clinical experience and from the principles underpinning their clinical methods. This experience and thinking calls forth particular contributions GPs can and should make to debate and action. Discussion We contend that the privileged experience and GP way of thinking can make valuable contributions when applied to climate change solutions. These include a lifetime of experience, reflection and epistemological application to first doing no harm, managing uncertainty, the ability to make necessary decisions while possessing incomplete information, an appreciation of complex adaptive systems, maintenance of homeostasis, vigilance for unintended consequences, and an appreciation of the importance of transdisciplinarity and interprofessionalism. Summary General practitioners have a long history of public health advocacy and in the case of climate change may bring a way of approaching complex human problems that could be applied to the dilemmas of climate change.

    Reducing insolation has been proposed as a geoengineering response to global warming. Here we present the results of climate model simulations of a unique Geoengineering Model Intercomparison Project Testbed experiment to investigate the benefits and risks of a scheme that would brighten certain oceanic regions. The National Center for Atmospheric Research CESM CAM4-Chem global climate model was modified to simulate a scheme in which the albedo of the ocean surface is increased over the subtropical ocean gyres in the Southern Hemisphere. In theory, this could be accomplished using a stable, nondispersive foam, comprised of tiny, highly reflective microbubbles. Such a foam has been developed under idealized conditions, although deployment at a large scale is presently infeasible. We conducted three ensemble members of a simulation (G4Foam) from 2020 through to 2069 in which the albedo of the ocean surface is set to 0.15 (an increase of 150 %) over the three subtropical ocean gyres in the Southern Hemisphere, against a background of the RCP6.0 (representative concentration pathway resulting in +6 W m-2 radiative forcing by 2100) scenario. After 2069, geoengineering is ceased, and the simulation is run for an additional 20 years. Global mean surface temperature in G4Foam is 0.6 K lower than RCP6.0, with statistically significant cooling relative to RCP6.0 south of 30° N. There is an increase in rainfall over land, most pronouncedly in the tropics during the June-July-August season, relative to both G4SSA (specified stratospheric aerosols) and RCP6.0. Heavily populated and highly cultivated regions throughout the tropics, including the Sahel, southern Asia, the Maritime Continent, Central America, and much of the Amazon experience a statistically significant increase in precipitation minus evaporation.

    The role of convection was examined in trace gas transport and ozone production in a tropical dry season squall line sampled on August 3, 1985, during NASA Global Tropospheric Experiment/Amazon Boundary Layer Experiment 2A (NASA GTE/ABLE 2A) in Amazonia, Brazil. Two types of analyses were performed. Transient effects within the cloud are examined with a combination of two-dimensional cloud and one-dimensional photochemical modeling. Tracer analyses using the cloud model wind fields yield a series of cross sections of NO(x), CO, and O3 distribution during the lifetime of the cloud; these fields are used in the photochemical model to compute the net rate of O3 production. At noon, when the cloud was mature, the instantaneous ozone production potential in the cloud is between 50 and 60 percent less than in no-cloud conditions due to reduced photolysis and cloud scavenging of radicals. Analysis of cloud inflows and outflows is used to differentiate between air that is undisturbed and air that has been modified by the storm. These profiles are used in the photochemical model to examine the aftereffects of convective redistribution in the 24-hour period following the storm. Total tropospheric column O3 production changed little due to convection because so little NO(x) was available in the lower troposphere. However, the integrated O3 production potential in the 5- to 13-km layer changed from net destruction to net production as a result of the convection. The conditions of the August 3, 1985, event may be typical of the early part of the dry season in Amazonia, when only minimal amounts of pollution from biomass burning have been transported into the region.

    South Asian summer monsoon (June through September) rainfall simulation and its potential future changes are evaluated in a multi-model ensemble of global coupled climate models outputs under World Climate Research Program Coupled Model Intercomparison Project (WCRP CMIP3) dataset. The response of South Asian summer monsoon to a transient increase in future anthropogenic radiative forcing is investigated for two time slices, middle (2031-2050) and end of the twenty-first century (2081-2100), in the non-mitigated Special Report on Emission Scenarios B1, A1B and A2 .There is large inter-model variability in the simulation of spatial characteristics of seasonal monsoon precipitation. Ten out of the 25 models are able to simulate space-time characteristics of the South Asian monsoon precipitation reasonably well. The response of these selected ten models has been examined for projected changes in seasonal monsoon rainfall. The multi-model ensemble of these ten models projects a significant increase in monsoon precipitation with global warming. The substantial increase in precipitation is observed over western equatorial Indian Ocean and southern parts of India. However, the monsoon circulation weakens significantly under all the three climate change experiments. Possible mechanisms for the projected increase in precipitation and for precipitation-wind paradox have been discussed. The surface temperature over Asian landmass increases in pre-monsoon months due to global warming and heat low over northwest India intensifies. The dipole snow configuration over Eurasian continent strengthens in warmer atmosphere, which is conducive for the enhancement in precipitation over Indian landmass. No notable changes have been projected in the El Niño-Monsoon relationship, which is useful for predicting interannual variations of the monsoon.

    Full Text Available Many researches and practical experiences clearly indicate the existence of a strong relationship between entrepreneurial activities and the business environment in which these activities are initiated. Although this topic has been quite ignored until the late twentieth century, a lot of studies and consulting practice have contributed to the fact that there are now a number of theories concerning mentioned correlation. These theories aim to offer a model that would provide better utilization of the possibilities from the business environment which could be very important for the development from both macroeconomic and microeconomic aspects. An increasing number of articles on this topic says enough about its importance, and numerous researches by many reputable globally recognized institutions go in favor of this claim. There are many indicators that observe the economic situation in a country or a region from different aspects, so the analyses of these indicators make it possible to determine the specific relationships between entrepreneurial activities and the local and the global business environment. Given the complexity of these relations, the impact cannot be observed partially, without taking into consideration other important factors, but more detailed analyses, however, result in some useful conclusions, which in the proper context can have a positive impact on many economic factors. It is very important to emphasize the fact that the correlation between the business environment and entrepreneurial activities is bidirectional, since this influence is mutual, so that changes in one of these factors can and usually cause some modifications in the other. Frequent series of such iterations actually lead to changes in the business environment, while entrepreneurial activity changes its shape and affects the economy of a country or a region, which is of particular importance for its competitiveness in the era of globalization.

    Full Text Available An Observing System Simulation Experiment (OSSE system has been implemented at the National Oceanographic and Atmospheric Administration Earth Systems Research Laboratory in the US as part of an international Joint OSSE effort. The setup of the OSSE consists of a Nature Run from a 13-month free run of the European Center for Medium-Range Weather Forecasts operational model, synthetic observations developed at the National Centers for Environmental Prediction (NCEP and the National Aeronautics and Space Administration Global Modelling and Assimilation Office, and an operational version of the NCEP Gridpoint Statistical Interpolation data assimilation and Global Forecast System numerical weather prediction model. Synthetic observations included both conventional observations and the following radiance observations: AIRS, AMSU-A, AMSU-B, HIRS2, HIRS3, MSU, GOES radiance and OSBUV. Calibration was performed by modifying the error added to the conventional synthetic observations to achieve a match between data denial impacts on the analysis state in the OSSE system and in the real data system. Following calibration, the performance of the OSSE system was evaluated in terms of forecast skill scores and impact of observations on forecast fields.

    2010-01-01

    The Global Trigger is part of the Level-1 Trigger of the CMS experiment at CERN, with the task to find the most interesting events corresponding to a rate of 100 kHz from the basic Large Hadron Collider interaction rate of 40 MHz. It is expected to render a decision within 3:2 $\\mu$s, which necessitates an implementation using custom hardware. The implementation makes heavy use of Field Programmable Gate Array (FPGA) technology to reconcile the performance requirements with the need for exibility. The complexity of the Global Trigger system (13 boards with 51 FPGA chips) makes it vulnerable to a multitude of errors, from electrical errors such as bad solder joints or plug contacts up to logical errors in the implementation of the firmrmware and the configuration software. The goal of the work described in this thesis was to provide an integrated system that allows users to easily determine whether the system is working correctly and assists experts in tracking down the internal causes of such errors within th...

    Anthropogenic changes in climate and land use are driving changes in migration patterns of birds worldwide. Spatial changes in migration have been related to long-term temperature trends, but the intrinsic mechanisms by which migratory species adapt to environmental change remain largely unexplored. We show that, for a long-lived social species, older birds with more experience are critical for innovating new migration behaviours. Groups containing older, more experienced individuals establish new overwintering sites closer to the breeding grounds, leading to a rapid population-level shift in migration patterns. Furthermore, these new overwintering sites are in areas where changes in climate have increased temperatures and where food availability from agriculture is high, creating favourable conditions for overwintering. Our results reveal that the age structure of populations is critical for the behavioural mechanisms that allow species to adapt to global change, particularly for long-lived animals, where changes in behaviour can occur faster than evolution.

    Carbonyl chlorofluoride (COCIF) is an important reservoir of chlorine and fluorine in the Earth's atmosphere. Satellite-based remote sensing measurements of COCIF, obtained by the Atmospheric Chemistry Experiment (ACE) for a time period spanning February 2004 through April 2007, have been used in a global distribution study. There is a strong source region for COCIF in the tropical stratosphere near 27 km. A layer of enhanced COCIF spans the low- to mid-stratosphere over all latitudes, with volume mixing ratios of 40-100 parts per trillion by volume, largest in the tropics and decreasing toward the poles. The COCIF volume mixing ratio profiles are nearly zonally symmetric, but they exhibit a small hemispheric asymmetry that likely arises from a hemispheric asymmetry in the parent molecule CCl3 F. Comparisons are made with a set of in situ stratospheric measurements from the mid-1980s and with predictions from a 2-D model.

  4. The Social Lives of Global Policies against Malaria: Conceptual Considerations, Past Experiences, and Current Issues.

    2017-07-01

    While a casual observer might easily get the impression that global policies against malaria have unanimous support, there are strongly divergent perspectives on malaria control. Analyzing ethnographic and historical material through a political science lens, I foreground the social negotiation of malaria both as an illness experience of affected populations and as a disease problem defined by experts. Taking the interrelationship between problems, solutions, and solution providers as a point of departure, I reconstruct recurrent tensions and social mechanisms that can account for the tendency to downplay conflicts and to produce technical-biomedical solutions that seem to be irresistible. This helps to overcome the perception that current policies have no alternatives and that aiming directly for malaria eradication is the only form of sustainability in times of resistances when "saving the established technical-biomedical solutions" has become a key concern.

    1999-01-01

    The Global Ozone Monitoring Experiment (GOME) is a new instrument aboard the European Space Agency's (ESA) Second European Remote Sensing Satellite (ERS-2), which was launched in April 1995. The main scientific objective of the GOME mission is to determine the global distribution of ozone and several other trace gases, which play an important role in the ozone chemistry of the earth's stratosphere and troposphere. GOME measures the sunlight scattered from the earth's atmosphere and/or reflected by the surface in nadir viewing mode in the spectral region 240-790 nm at a moderate spectral resolution of between 0.2 and 0.4 nm. Using the maximum 960-km across-track swath width, the spatial resolution of a GOME ground pixel is 40 × 320 km2 for the majority of the orbit and global coverage is achieved in three days after 43 orbits.Operational data products of GOME as generated by DLR-DFD, the German Data Processing and Archiving Facility (D-PAF) for GOME, comprise absolute radiometrically calibrated earthshine radiance and solar irradiance spectra (level 1 products) and global distributions of total column amounts of ozone and NO2 (level 2 products), which are derived using the DOAS approach (Differential Optical Absorption Spectroscopy). (Under certain conditions and some restrictions, the operational data products are publically available from the European Space Agency via the ERS Helpdesk.)In addition to the operational data products, GOME has delivered important information about other minor trace gases such as OClO, volcanic SO2, H2CO from biomass burning, and tropospheric BrO. Using an iterative optimal estimation retrieval scheme, ozone vertical profiles can be derived from the inversion of the UV/VIS spectra. This paper reports on the GOME instrument, its operation mode, and the retrieval techniques, the latter with particular emphasis on DOAS (total column retrieval) and advanced optimal estimation (ozone profile retrieval).Observation of ozone depletion in the

    The objective of this article is to describe the key areas of consideration for global/international advanced pharmacy practice experience (G/I APPE) preceptors, students and learning objectives. At the 2013 Annual Meeting of the American Association of Colleges of Pharmacy (AACP), the GPE SIG prepared and presented an initial report on the G/IAPPE initiatives. Round table discussions were conducted at the 2014 AACP Annual Meeting to document GPE SIG member input on key areas in the report. Literature search of PubMed, Google Scholar and EMBASE with keywords was conducted to expand this report. In this paper, considerations related to preceptors and students and learning outcomes are described. Preceptors for G/I APPEs may vary based on the learning outcomes of the experience. Student learning outcomes for G/I APPEs may vary based on the type of experiential site. Recommendations and future directions for development of G/IAPPEs are presented. Development of a successful G/I APPE requires significant planning and consideration of appropriate qualifications for preceptors and students.

Most studies have compared sites within and across regions with variations in land-use history, but not necessarily with standardized treatments in an experimental framework. The trends that have emerged from this research is that characteristics of leaf traits such as specific leaf area (SLA) correlate with carbon acquisition strategies known to influence ecosystem functioning. SLA has been found to represent a plant's investment in growing light-capturing area per dry mass content. Species with a relatively high SLA tend to have a higher rate of return on the resources invested into making tissue (cheaper leaves in terms of energy and resources needed to produce them) when compared to species with a lower SLA (more expensive leaves to produce). Few studies have examined quantitatively measured traits in an experimental framework. The Nutrient Network experiment, globally distributed experiment, presents a unique opportunity to examine the response of functional traits across grassland ecosystems characterised by a diverse range of

    The project was conducted during the period from 7/1/2012 to 6/30/2017 with three major tasks: (1) data synthesis and development of data assimilation (DA) techniques to constrain modeled ecosystem feedback to climate change; (2) applications of DA techniques to improve process models at different scales from ecosystem to regions and the globe; and 3) improvements of modeling soil carbon (C) dynamics by land surface models. During this period, we have synthesized published data from soil incubation experiments (e.g., Chen et al., 2016; Xu et al., 2016; Feng et al., 2016), global change experiments (e.g., Li et al., 2013; Shi et al., 2015, 2016; Liang et al., 2016) and fluxnet (e.g., Niu et al., 2012., Xia et al., 2015; Li et al., 2016). These data have been organized into multiple data products and have been used to identify general mechanisms and estimate parameters for model improvement. We used the data sets that we collected and the DA techniques to improve model performance of both ecosystem models and global land models. The objectives are: 1) to improve model simulations of litter and soil carbon storage (e.g., Schädel et al., 2013; Hararuk and Luo, 2014; Hararuk et al., 2014; Liang et al., 2015); 2) to explore the effects of CO2, warming and precipitation on ecosystem processes (e.g., van Groenigen et al., 2014; Shi et al., 2015, 2016; Feng et al., 2017); and 3) to estimate parameters variability in different ecosystems (e.g., Li et al., 2016). We developed a traceability framework, which was based on matrix approaches and decomposed the modeled steady-state terrestrial ecosystem carbon storage capacity into four can trace the difference in ecosystem carbon storage capacity among different biomes to four traceable components: net primary productivity (NPP), baseline C residence times, environmental scalars and climate forcing (Xia et al., 2013). With this framework, we can diagnose the differences in modeled carbon storage across ecosystems, biomes, and

    Global Memory Net (GMNet) is intended to be an effective gateway to the world cultural, historical, and heritage image collections from selected academic educational and research partners in the world. Much of these unique collections of great value to education and research are not currently accessible due to distance, form, and technical barriers. This project is to find new ways to enable users to access and exploit these significant research collections via global network. As GMNet is ending its first 5-year phase in October 2005, it has contributed substantially to the community building in digital library development by accommodating numerous collaborators and technical staff from various parts of the world to spend 3 to 5 months as a full-member of the GMNet team in Boston. They have come from different parts of China-such as Sichuan, Hainan, Shanghai and Xi'an;Croatia; and Hanoi, Vietnam. In addition to contribute to the overall system development and enhancement of system functionalities, they have brought valuable sample image collections of their own institutions/countries, and actually developed prototype collections as a part of GMNet. This paper describes the exciting and productive experience of the first of this visiting research group in developing the GMNet's Version 2.0 PHP-based system under Prof. Chen's overall supervision. It also describes both the system's technical level structure-user/Web-based application/data, and complex functionalities with multi-collection,multi-lingual, multi-modal searching capabilities; system management capabilities; as well as provisions for user uploads and retrieval for our own projects. This Version 2.0 system is built on the Linux/Apache/PHP/MySQL platform. What is described in this paper is an actual case which has formed a base for further new development by others in the research group. It demonstrates fully the value of the synergistic collaboration among global partners for universal digital library

    2012-05-01

    A hierarchy of global spectral circulation models is introduced ranging from the shallow-water system via the primitive-equation dynamical core of the atmosphere to the Planet Simulator as a Global Climate Model (GCM) of Intermediate Complexity (MIC) which can be used to run climate and paleo-climate simulations for time scales up to ten thousand years or more in an acceptable real time. The priorities in development are set to speed, easy handling and portability with a modular structure suitable for problem-dependent configuration. Adaptions exist for the planetary atmospheres of Mars and of Saturn's moon Titan and are being extended. Common coupling interfaces enable the addition of ocean, ice, vegetation models and more. An interactive mode with a Model Starter and a Graphical User Interface (GUI) is available to select a configuration from the available model suite, to set its parameters and inspect atmospheric fields while changing the models' parameters on the fly. This is especially useful for teaching, debugging and tuning of parameterizations. An updated overview of the model suite's features is presented based on the Earth-like climate model Planet Simulator with mixed-layer ocean introducing static and memory hysteresis in terms of a parameter sweep of the solar constant and CO2 concentrations. The static hysteresis experiment demonstrates that the solar constant varying by 20% reveals warm and snowball Earth climate regimes depending on the history of the system. This hysteresis subjected to a thermodynamic analysis shows the following features: i) Both climate regimes are characterized by global mean surface temperature and entropy growing with increasing solar constant. ii) The climate system's efficiency decreases (increases) with increasing solar constant in present-day warm (snowball) climate conditions. iii) Climate transitions near bifurcation points are characterized by high efficiency associated with the system's large distance from the stable

    As a component of the Earth's hydrologic cycle, and especially at higher latitudes,falling snow creates snow pack accumulation that in turn provides a large proportion of the fresh water resources required by many communities throughout the world. To assess the relationships between remotely sensed snow measurements with in situ measurements, a winter field project, termed the Global Precipitation Measurement (GPM) mission Cold Season Precipitation Experiment (GCPEx), was carried out in the winter of 2011-2012 in Ontario, Canada. Its goal was to provide information on the precipitation microphysics and processes associated with cold season precipitation to support GPM snowfall retrieval algorithms that make use of a dual-frequency precipitation radar and a passive microwave imager on board the GPM core satellite,and radiometers on constellation member satellites. Multi-parameter methods are required to be able to relate changes in the microphysical character of the snow to measureable parameters from which precipitation detection and estimation can be based. The data collection strategy was coordinated, stacked, high-altitude and in-situ cloud aircraft missions with three research aircraft sampling within a broader surface network of five ground sites taking in-situ and volumetric observations. During the field campaign 25 events were identified and classified according to their varied precipitation type, synoptic context, and precipitation amount. Herein, the GCPEx fieldcampaign is described and three illustrative cases detailed.

    Large-scale magnetic fields have been observed in widely different types of astrophysical objects. These magnetic fields are believed to be caused by the so-called dynamo effect. Could a large-scale magnetic field grow out of turbulence (i.e. the alpha dynamo effect)? How could the topological properties and the complexity of magnetic field as a global quantity, the so called magnetic helicity, be important in the dynamo effect? In addition to understanding the dynamo mechanism in astrophysical accretion disks, anomalous angular momentum transport has also been a longstanding problem in accretion disks and laboratory plasmas. To investigate both dynamo and momentum transport, we have performed both numerical modeling of laboratory experiments that are intended to simulate nature and modeling of configurations with direct relevance to astrophysical disks. Our simulations use fluid approximations (Magnetohydrodynamics - MHD model), where plasma is treated as a single fluid, or two fluids, in the presence of electromagnetic forces. Our major physics objective is to study the possibility of magnetic field generation (so called MRI small-scale and large-scale dynamos) and its role in Magneto-rotational Instability (MRI) saturation through nonlinear simulations in both MHD and Hall regimes.

  16. Globalization and medical tourism: the North American experience Comment on "Patient mobility in the global marketplace: a multidisciplinary perspective".

    Bustamante, Arturo Vargas

    2014-06-01

    Neil Lunt and Russel Mannion provide an overview of the current state of the medical tourism literature and propose areas for future research in health policy and management. The authors also identify the main unanswered questions in this field ranging from the real size of the medical tourism market to the particular health profiles of transnational patients. In addition, they highlight unexplored areas of research from health economics, ethics, policy and management perspectives. To this very insightful editorial I would add the international trade perspective. While globalization has permeated labor and capital, services such as healthcare are still highly regulated by governments, constrained to regional or national borders and protected by organized interests. Heterogeneity of healthcare regulations and lack of cross-country reciprocity agreements act as barriers to the development of more widespread and dynamic medical tourism markets. To picture these barriers to transnational health services I use evidence from North America, identifying different "pull and push factors" for medical tourist in this region, discussing how economic integration and healthcare reform might shift the incentives to utilize healthcare abroad.

    The Mars Global Surveyor (MGS) spacecraft, launched on November 7, 1996, carries an experimental space-to-ground telecommunications link at Ka-band (32 GHz) along with the primary X-band (8.4-GHz) downlink. The signals are simultaneously transmitted from a 1.5-m-diameter parabolic antenna on MGS and received by a beam-waveguide (BWG) research and development (R&D) 34-meter a ntenna located in NASA's Goldstone Deep Space Network (DSN) complex near Barstow, California. This Ka-band link experiment (KaBLE-II) allows the performances of the Ka-band and X-band signals to be compared under nearly identical conditions. The two signals have been regularly tracked during the past 2 years. This article presents carrier-signal-level data (P_c/N_o) for both X-band and Ka-band acquired over a wide range of station elevation angles, weather conditions, and solar elongation angles. The cruise phase of the mission covered the period from launch (November 7, 1996) to Mars orbit capture (September 12, 1997). Since September 12, 1997, MGS has been in orbit around Mars. The measurements confirm that Ka-band could increase data capacity by at least a factor of three (5 dB) as compared with X-band. During May 1998, the solar corona experiment, in which the effects of solar plasma on the X-band and Ka-band links were studied, was conducted. In addition, frequency and difference frequency (f_x - f_(Ka)/3.8), ranging, and telemetry data results are presented. MGS/KaBLE-II measured signal strengths (for 54 percent of the experiments conducted) that were in reasonable agreement with predicted values based on preflight knowledge, and frequency residuals that agreed between bands and whose statistics were consistent with expected noise sources. For passes in which measured signal strengths disagreed with predicted values, the problems were traced to known deficiencies, for example, equipment operating under certain conditions, such as a cold Ka-band solid-state power amplifier (SSPA

    Increasing demand for global health education in medical training has driven the growth of educational programs predicated on a model of short-term medical service abroad. Almost two-thirds of matriculating medical students expect to participate in a global health experience during medical school, continuing into residency and early careers. Despite positive intent, such short-term experiences in global health (STEGHs) may exacerbate global health inequities and even cause harm. Growing out of the "medical missions" tradition, contemporary participation continues to evolve. Ethical concerns and other disciplinary approaches, such as public health and anthropology, can be incorpo rated to increase effectiveness and sustainability, and to shift the culture of STEGHs from focusing on trainees and their home institutions to also considering benefits in host communities and nurtur ing partnerships. The authors propose four core principles to guide ethical development of educational STEGHs: (1) skills building in cross-cultural effective ness and cultural humility, (2) bidirectional participatory relationships, (3) local capacity building, and (4) long-term sustainability. Application of these principles highlights the need for assessment of STEGHs: data collection that allows transparent compar isons, standards of quality, bidirectionality of agreements, defined curricula, and ethics that meet both host and sending countries' standards and needs. To capture the enormous potential of STEGHs, a paradigm shift in the culture of STEGHs is needed to ensure that these experiences balance training level, personal competencies, medical and cross-cultural ethics, and educational objectives to minimize harm and maximize benefits for all involved.

    Global developmental delay (GDD) and intellectual disability (ID) are common reasons for consultation in paediatric neurology. Results from aetiological evaluations of children with GDD/ID vary greatly, and consequently, there is no universal consensus regarding which studies should be performed. We review our experience with determining aetiological diagnoses for children with GDD/ID who were monitored by the paediatric neurology unit over the 5-year period between 2006 and 2010. During the study period, 995 children with GDD/ID were monitored. An aetiological diagnosis was established for 309 patients (31%), but not in 686 (69%), despite completing numerous tests. A genetic cause was identified in 142 cases (46% of the total aetiologies established), broken down as 118 cases of genetic encephalopathy and 24 of metabolic hereditary diseases. Our data seem to indicate that diagnosis is easier when GDD/ID is associated with cerebral palsy, epilepsy, infantile spasms/West syndrome, or visual deficit, but more difficult in cases of autism spectrum disorders. Genetic studies provide an increasing number of aetiological diagnoses, and they are also becoming the first step in diagnostic studies. Array CGH (microarray-based comparative genomic hybridisation) is the genetic test with the highest diagnostic yield in children with unexplained GDD/ID. The cost-effectiveness of complementary studies seems to be low if there are no clinically suspected entities. However, even in the absence of treatment, aetiological diagnosis is always important in order to provide genetic counselling and possible prenatal diagnosis, resolve family (and doctors') queries, and halt further diagnostic studies.

    2014-01-01

    Global health governance benefits from participants well-versed in the realities of international policy-making. Consequently, educational programmes must establish more opportunities for students to engage in global health policy development. This paper examines a unique global health governance and diplomacy practicum programme at the University of Southern California, designed for Master of Public Health candidates. Through the programme, students act as official non-governmental delegates to the World Health Assembly in Geneva, Switzerland through organisational partnerships. Students and collaborating organisations were asked to complete an online post-participation survey examining the perceived quality of the experience. Through the survey, students indicated reinforcement of classroom learning, continued or heightened interest in global health policy and enthusiasm in recommending the programme to other students. Organisations perceived students to be adequately prepared and indicated their continued desire to work with students in the programme. The data collected suggest that the programme was successful in providing students with a worthwhile experience that developed skills in global health diplomacy and promoted interest and critical thinking concerning international policy-making processes. A discussion of strengths and challenges serves as a blueprint for the creation of future practicum programmes.

    2017-01-01

    Coagulopathy may be a serious complicating or contributing factor to postpartum hemorrhage (PPH), and should be promptly recognized to ensure proper bleeding management. This study aims to evaluate the approaches of obstetrician-gynecologists worldwide towards assessing massive PPH caused by underlying bleeding disorders. A quantitative survey was completed by 302 obstetrician-gynecologists from 6 countries (the UK, France, Germany, Italy, Spain, and Japan). The survey included questions on the use of hematologic laboratory studies, interpretation of results, laboratory's role in coagulation assessments, and experience with bleeding disorders. Overall, the most common definitions of "massive" PPH were >2,000 mL (39%) and >1,500 mL (34%) blood loss. The most common criteria for rechecking a "stat" complete blood count and for performing coagulation studies were a drop in blood pressure (73%) and ongoing visible bleeding (78%), respectively. Laboratory coagulation (prothrombin time/activated partial thromboplastin time [PT/aPTT]) and factor VIII/IX assays were performed on-site more often than were mixing studies (laboratory coagulation studies, 93%; factor VIII/IX assays, 63%; mixing studies, 22%). Most commonly consulted sources of additional information were colleagues within one's own specialty (68%) and other specialists (67%). Most respondents had consulted with a hematologist (78%; least, Germany [56%]; greatest, UK [98%]). The most common reason for not consulting was hematologist unavailability (44%). The most commonly reported thresholds for concern with PT and aPTT were 13 to 20 seconds (36%) and 30 to 45 seconds (50%), respectively. Most respondents reported having discovered an underlying bleeding disorder (58%; least, Japan [35%]; greatest, Spain [74%]). Global survey results highlight similarities and differences between countries in how PPH is assessed and varying levels of obstetrician-gynecologist experience with identification of underlying

    Global temperature is expected to rise throughout this century, and blooms of cyanobacteria in lakes and estuaries are predicted to increase with the current level of global warming. The potential environmental, economic and sanitation repercussions of these blooms have attracted considerable attention among the world's scientific communities, water management agencies and general public. Of particular concern is the worldwide occurrence of hepatotoxic cyanobacteria posing a serious threat to global public health. Here, we highlight plausible effects of global warming on physiological and molecular changes in these cyanobacteria and resulting effects on hepatotoxin production. We also emphasize the importance of understanding the natural biological function(s) of hepatotoxins, various mechanisms governing their synthesis, and climate-driven changes in food-web interactions, if we are to predict consequences of the current and projected levels of global warming for production and accumulation of hepatotoxins in aquatic ecosystems.

    Agricultural systems differ significantly throughout the world, making a 'one size fits all' approach to remote sensing and monitoring of agricultural landscapes problematic. The Joint Experiment for Crop Assessment and Monitoring (JECAM) was established in 2009 to bring together the global scientific community to work towards a set of best practices and recommendations for using earth observation data to map, monitor and report on agricultural productivity globally across an array of diverse agricultural systems. These methods form the research and development component of the Group on Earth Observation Global Agricultural Monitoring (GEOGLAM) initiative to harmonize global monitoring efforts and increase market transparency. The JECAM initiative brings together researchers from a large number of globally distributed, well monitored agricultural test sites that cover a range of crop types, cropping systems and climate regimes. Each test site works independently as well as together across multiple sites to test methods, sensors and field data collection techniques to derive key agricultural parameters, including crop type, crop condition, crop yield and soil moisture. The outcome of this project will be a set of best practices that cover the range of remote sensing monitoring and reporting needs, including satellite data acquisition, pre-processing techniques, information retrieval and ground data validation. These outcomes provide the research and development foundation for GEOGLAM and will help to inform the development of the GEOGLAM "system of systems" for global agricultural monitoring. The outcomes of the 2014 JECAM science meeting will be discussed as well as examples of methods being developed by JECAM scientists.

    The Diviner Lunar Radiometer Experiment onboard the Lunar Reconnaissance Orbiter (LRO) has been acquiring solar reflectance and mid-infrared radiance measurements nearly continuously since July of 2009. Diviner is providing the most comprehensive view of how regoliths on airless bodies store and exchange thermal energy with the space environment. Approximately a quarter trillion calibrated radiance measurements of the Moon, acquired over 5.5 years by Diviner, have been compiled into a 0.5° resolution global dataset with a 0.25 h local time resolution. Maps generated with this dataset provide a global perspective of the surface energy balance of the Moon and reveal the complex and extreme nature of the lunar surface thermal environment. Our achievable map resolution, both spatially and temporally, will continue to improve with further data acquisition. Daytime maximum temperatures are sensitive to the albedo of the surface and are ∼387-397 K at the equator, dropping to ∼95 K just before sunrise, though anomalously warm areas characterized by high rock abundances can be > 50 K warmer than the zonal average nighttime temperatures. An asymmetry is observed between the morning and afternoon temperatures due to the thermal inertia of the lunar regolith with the dusk terminator ∼30 K warmer than the dawn terminator at the equator. An increase in albedo with incidence angle is required to explain the observed decrease in temperatures with latitude. At incidence angles exceeding ∼40°, topography and surface roughness influence temperatures resulting in increasing scatter in temperatures and anisothermality between Diviner channels. Nighttime temperatures are sensitive to the thermophysical properties of the regolith. High thermal inertia (TI) materials such as large rocks, remain warmer during the long lunar night and result in anomalously warm nighttime temperatures and anisothermality in the Diviner channels. Anomalous maximum and minimum temperatures are

    2016-01-01

    Modal linear stability analysis has proven very successful in the analysis of coherent structures of turbulent flows. Formally, it describes the evolution of a disturbance in the limit of infinite time. In this work we apply modal linear stability analysis to a turbulent swirling jet undergoing a control parameter transient. The flow undergoes a transition from a non-vortex breakdown state to a state with a strong recirculation bubble and the associated global mode. High-speed Particle Image Velocimetry (PIV) measurements are the basis for a local linear stability analysis of the temporarily evolving base flow. This analysis reveals that the onset of the global mode is strongly linked to the formation of the internal stagnation point. Several transition scenarios are discussed and the ability of a frequency selection criterion to predict the wavemaker location, frequency and growth rate of the global mode are evaluated. We find excellent agreement between the linear global mode frequency and the experimental ...

  11. The effect of harmonized emissions on aerosol properties in global models – an AeroCom experiment

    2007-08-01

    Full Text Available The effects of unified aerosol sources on global aerosol fields simulated by different models are examined in this paper. We compare results from two AeroCom experiments, one with different (ExpA and one with unified emissions, injection heights, and particle sizes at the source (ExpB. Surprisingly, harmonization of aerosol sources has only a small impact on the simulated inter-model diversity of the global aerosol burden, and consequently global optical properties, as the results are largely controlled by model-specific transport, removal, chemistry (leading to the formation of secondary aerosols and parameterizations of aerosol microphysics (e.g., the split between deposition pathways and to a lesser extent by the spatial and temporal distributions of the (precursor emissions.

    The burdens of black carbon and especially sea salt become more coherent in ExpB only, because the large ExpA diversities for these two species were caused by a few outliers. The experiment also showed that despite prescribing emission fluxes and size distributions, ambiguities in the implementation in individual models can lead to substantial differences.

    These results indicate the need for a better understanding of aerosol life cycles at process level (including spatial dispersal and interaction with meteorological parameters in order to obtain more reliable results from global aerosol simulations. This is particularly important as such model results are used to assess the consequences of specific air pollution abatement strategies.

    2011-11-15

    In this study, a zonally-averaged statistical climate model (SDM) is used to investigate the impact of global warming on the distribution of the geobotanic zones over the globe. The model includes a parameterization of the biogeophysical feedback mechanism that links the state of surface to the atmosphere (a bidirectional interaction between vegetation and climate). In the control experiment (simulation of the present-day climate) the geobotanic state is well simulated by the model, so that the distribution of the geobotanic zones over the globe shows a very good agreement with the observed ones. The impact of global warming on the distribution of the geobotanic zones is investigated considering the increase of CO{sub 2} concentration for the B1, A2 and A1FI scenarios. The results showed that the geobotanic zones over the entire earth can be modified in future due to global warming. Expansion of subtropical desert and semi-desert zones in the Northern and Southern Hemispheres, retreat of glaciers and sea-ice, with the Arctic region being particularly affected and a reduction of the tropical rainforest and boreal forest can occur due to the increase of the greenhouse gases concentration. The effects were more pronounced in the A1FI and A2 scenarios compared with the B1 scenario. The SDM results confirm IPCC AR4 projections of future climate and are consistent with simulations of more complex GCMs, reinforcing the necessity of the mitigation of climate change associated to global warming.

    Full Text Available Measuring household food insecurity represents a challenge due to the complexity and wide array of factors associated with this phenomenon. For over one decade, researchers and agencies throughout the world have been using and assessing the validity of variations of the United States Department of Agriculture Household Food Security Supplemental Module. Thanks to numerous studies of diverse design, size, and purpose, the Household Food Security Supplemental Module has shown its suitability to directly evaluate the perceptions of individuals on their food security status. In addition, challenges and limitations are becoming clearer and new research questions are emerging as the process advances. The purpose of this article is to describe the development, validation procedures, and use of the Household Food Security Supplemental Module in very diverse settings. The most common Household Food Security Supplemental Module related studies have been conducted using criterion validity, Rasch modeling and Cronbach-Alpha Coefficient. It is critical that researchers, policy makers, governmental and non-governmental agencies intensify their efforts to further develop tools that provide valid and reliable measures of food security in diverse population groups. Additional work is needed to synthesize a universally applicable tool able to capture the global human phenomenon of food insecurity.Medir a insegurança alimentar domiciliar representa um desafio devido à complexidade e ao vasto número de fatores associados a este fenômeno.

    It is widely acknowledged that austerity measures in the wake of the global financial crisis are starting to undermine population health results. Yet, few research studies have focused on the ways in which the financial crisis and the ensuing 'Great Recession' have affected health equity, especially through their impact on social determinants of health; neither has much attention been given to the health consequences of the fiscal austerity regime that quickly followed a brief period of counter-cyclical government spending for bank bailouts and economic stimulus. Canada has not remained insulated from these developments, despite its relative success in maneuvering the global financial crisis. The study draws on three sources of evidence: A series of semi-structured interviews in Ottawa and Toronto, with key informants selected on the basis of their expertise (n = 12); an analysis of recent (2012) Canadian and Ontario budgetary impacts on social determinants of health; and documentation of trend data on key social health determinants pre- and post the financial crisis. The findings suggest that health equity is primarily impacted through two main pathways related to the global financial crisis: austerity budgets and associated program cutbacks in areas crucial to addressing the inequitable distribution of social determinants of health, including social assistance, housing, and education; and the qualitative transformation of labor markets, with precarious forms of employment expanding rapidly in the aftermath of the global financial crisis. Preliminary evidence suggests that these tendencies will lead to a further deepening of existing health inequities, unless counter-acted through a change in policy direction. This article documents some of the effects of financial crisis and severe economic decline on health equity in Canada. However, more research is necessary to study policy choices that could mitigate this effect. Since the policy response to a similar set of

    Paegle, J.; Baker, W. E.

    1985-01-01

    Several densities of tropical divergent wind data were included in a fourth-order GCM to examine the effects on the accuracy of the model predictions. The experiments covered assimilation of all available tropical wind data, no tropical wind data between 20 deg N and 20 deg S, only westerly tropical wind data and only easterly tropical wind data. The predictions were all made for the 200 mb upper troposphere. Elimination of tropical data produced excessively strong upper tropospheric westerlies which in turn amplified the globally integrated rotational flow kinetic energy by around 10 percent and doubled the global divergent flow kinetic energy. Retaining only easterly wind data, ameliorated most of the error. Inclusion of all the tropical wind data however, did not lead to overall positive effects, as the data were linked to tropical wave energetics and ageostrophic winds which were already assimilated in the model.

    Principal Recipients (PRs) receive money from the Global Fund to fight AIDS, Tuberculosis and Malaria (Global Fund) to manage and implement programs. However, little research has gone into understanding their opinions and experiences. This survey set out to describe these, thereby providing a baseline against which changes in PR opinions and experiences can be assessed as the recently introduced new funding model is rolled out. An internet based questionnaire was administered to 315 PRs. A total of 115 responded from 69 countries in Africa, Asia, Eastern Europe and Latin America. The study was conducted between September and December 2012. Three quarters of PRs thought the progress update and disbursement request (PU/DR) system was a useful method of reporting grant progress. However, most felt that the grant negotiation processes were complicated, and that the grant rating system did not reflect performance.While nearly all PRs were happy with the work being done by sub-Recipients (92%) and Fund Portfolio Managers (86%), fewer were happy with the Office of the Inspector General (OIG). Non-government PRs were generally less happy with the OIG's work compared to government PRs.Most PRs thought the Global Fund's Voluntary Pooled Procurement system made procurement easier. However, only 29% said the system should be made compulsory.When asked which aspects of the Global Fund's operations needed improvement, most PRs said that the Fund should re-define and clarify the roles of different actors, minimize staff turnover at its Secretariat, and shorten the grant application and approval processes. All these are currently being addressed, either directly or indirectly, under a new funding model. Vigorous assessments should nonetheless follow the roll-out of the new model to ensure the areas that are most likely to affect PR performance realize sustained improvement. Opinions and experiences with the Global Fund were varied, with PRs having good communication with Fund

Further research is required to foster beneficial shifts in policy advocacy, including resource allocation, and in the prioritization of adolescent programs in health and education systems, in communities and in workplaces. Adolescents are exposed to diverse interventions across all the countries under discussion; however there exist obstacles to realization of ASRH goals. In some countries, there exist a conflict of interest between national laws and global policy guidelines on ASRH; moreover national laws and policies are ambiguous and inconsistent. In addition, there have been strong negligence of vulnerable groups such as HIV positive adolescents, pregnant street youth; young sex workers; orphans; adolescents in conflict areas; adolescent refugees; adolescent girls working in the informal sectors and very young adolescents, likewise many adolescents in rural areas remain largely underserved. Furthermore there are consistently less disaggregated data available on adolescents’ key indicators for comparative purposes signifying considerable knowledge gaps. There are multiple obstacles to the realization of ASRH and need for research combining both qualitative and quantitative approaches to determine the extent to which factors are either conducive or impeding to consistency between global guidelines, national ASRH policies, and actual policy implementation.

  11. Perspectives of Complexity in Water Governance: Local Experiences of Global Trends

    Full Text Available Those responsible for water governance face great complexity. However, the conceptualisations of what comprises that complexity have been broad and inconsistent. When efforts are made to address the complexity in water governance, it is unclear whether the problems and the related solutions will be understood across the actors and institutions involved. This paper provides a review of the literature focused on global water governance to discern core themes that commonly characterise discussions of complexity. It then considers how the consequences of these issues are manifested at the local scale through an examination of empirical research of the Murray-Darling Basin Authority and the Prachinburi River Basin Committee. The results demonstrate that a history of a technical, depoliticised discourse is often perceived to contribute to complexity. The consequence is that when a severe ecological disturbance occurs within a river basin with poorly understood causes, few tools are available to support river basin organisations to address the political nature of these challenges. Additionally, a lack of clear authority structures has been recognised globally, but locally this can contribute to conflict amongst the 'governors' of water. Finally, a range of contested definitions and governance frameworks exists that contributes to complexity, but confronting the diversity of perspectives can lead to ethical dilemmas given that the decisions will affect the health and livelihoods of basin communities.

    Nowadays, environment is accepted to be an important element of our welfare. Our activities and societal status are strongly related with the quality of the environment where we live. On the other hand historical and cultural backgrounds shape importantly our views about the environment and how we act towards it in our daily life. In a context of globalization and increase of competition at international level, knowledge appears to be one of the key components for the advance of the word. Most of the knowledge produced comes from high level education institutions and research centres, which have responsibility to create and encourage critical thinking. Individuals aware of the problems can be more active and can push things forward. We think that environmental knowledge and awareness are fundamental for the future of the society. In order to develop better methodologies are developed if we have a better perception of students understanding of environmental problems. The objective of this work is to study the Lithuanian university level student's perception about some environmental challenges of our society. We selected several questions for the students rate according the relevance of the question, as "Air Pollution", "Waste Management", "Resources overexplotation", "Biodiversity reduction", "Human Overpopulation" "Poverty", "Global Warming/Climate change", Natural disasters", "Terrorism", "Economical crisis", "War and armed conflicts" and the "Spread of infectious diseases". We ask to the respondents to rate the importance using a likert scale (1=Not Important, 2= not so important, 3=important, 4=very important, 5=the most important). Among all the questions, the most rated where the Water pollution, the Spread of infectious diseases and Air Pollution and the less important where Biodiversity Reduction, Human overpopulation and climate change. These results helped us to identify where some efforts should be taken to raise student's awareness about global

    The vertical structure of the global atmosphere is analyzed for selected periods of the Special Observing Period I (SOP-I) for the Global Weather Experiment (GWE). The analysis consists of projection of the stream-function and velocity potential at 200 and 850 mb on spherical harmonics and of the wind and height fields on the normal modes of a linearized form of the primitive equations for a basic state at rest. The kinematic vertical structure is discussed in terms of correlation coefficients of the 200 mb and 850 mb winds and analysis of the internal and external normal modes of the primitive equations. The reliability of the results is checked by applying the same analysis methods to data sets obtained from three different institutions: Geophysical Fluid Dynamics Laboratory (GFDL), European Center for Medium Range Weather Forecasting (ECMWF), and Goddard Laboratory for the Atmospheres (GLA). It is found that, on a global basis, vertically reversing circulations are as important as the equivalent barotropic structures. For the verticaly reversing components, the gravity and mixed Rossby-gravity modes have contributions of the same order of magnitude as those of the Rossby modes in tropical latitudes.

    We describe a combined experiment-modelling framework to investigate the effects of ischaemia on the organisation of ventricular fibrillation in the human heart. In a series of experimental studies epicardial activity was recorded from 10 patients undergoing routine cardiac surgery. Ventricular fibrillation was induced by burst pacing, and recording continued during 2.5 min of global cardiac ischaemia followed by 30 s of coronary reflow. Modelling used a 2D description of human ventricular tissue. Global cardiac ischaemia was simulated by (i) decreased intracellular ATP concentration and subsequent activation of an ATP sensitive K⁺ current, (ii) elevated extracellular K⁺ concentration, and (iii) acidosis resulting in reduced magnitude of the L-type Ca²⁺ current I(Ca,L). Simulated ischaemia acted to shorten action potential duration, reduce conduction velocity, increase effective refractory period, and flatten restitution. In the model, these effects resulted in slower re-entrant activity that was qualitatively consistent with our observations in the human heart. However, the flattening of restitution also resulted in the collapse of many re-entrant waves to several stable re-entrant waves, which was different to the overall trend we observed in the experimental data. These findings highlight a potential role for other factors, such as structural or functional heterogeneity in sustaining wavebreak during human ventricular fibrillation with global myocardial ischaemia.

    A rapid expansion of trade liberalization in Thailand during the 1990s raised a critical question for policy transparency from various stakeholders. Particular attention was paid to a bilateral trade negotiation between Thailand and USA concerned with the impact of the 'Trade-Related Aspects of Intellectual Rights (TRIPS) plus' provisions on access to medicines. Other trade liberalization effects on health were also concerning health actors. In response, a number of interagency committees were established to engage with trade negotiations. In this respect, Thailand is often cited as a positive example of a country that has proactively sought, and achieved, trade and health policy coherence. This article investigates this relationship in more depth and suggests lessons for wider study and application of global health diplomacy (GHD). This study involved semi-structured interviews with 20 people involved in trade-related health negotiations, together with observation of 9 meetings concerning trade-related health issues. Capacity to engage with trade negotiations appears to have been developed by health actors through several stages; starting from the Individual (I) understanding of trade effects on health, through Nodes (N) that establish the mechanisms to enhance health interests, Networks (N) to advocate for health within these negotiations, and an Enabling environment (E) to retain health officials and further strengthen their capacities to deal with trade-related health issues. This INNE model seems to have worked well in Thailand. However, other contextual factors are also significant. This article suggests that, in building capacity in GHD, it is essential to educate both health and non-health actors on global health issues and to use a combination of formal and informal mechanisms to participate in GHD. And in developing sustainable capacity in GHD, it requires long term commitment and strong leadership from both health and non-health sectors.

  18. A global parallel model based design of experiments method to minimize model output uncertainty.

    Model-based experiment design specifies the data to be collected that will most effectively characterize the biological system under study. Existing model-based design of experiment algorithms have primarily relied on Fisher Information Matrix-based methods to choose the best experiment in a sequential manner. However, these are largely local methods that require an initial estimate of the parameter values, which are often highly uncertain, particularly when data is limited. In this paper, we provide an approach to specify an informative sequence of multiple design points (parallel design) that will constrain the dynamical uncertainty of the biological system responses to within experimentally detectable limits as specified by the estimated experimental noise. The method is based upon computationally efficient sparse grids and requires only a bounded uncertain parameter space; it does not rely upon initial parameter estimates. The design sequence emerges through the use of scenario trees with experimental design points chosen to minimize the uncertainty in the predicted dynamics of the measurable responses of the system. The algorithm was illustrated herein using a T cell activation model for three problems that ranged in dimension from 2D to 19D. The results demonstrate that it is possible to extract useful information from a mathematical model where traditional model-based design of experiments approaches most certainly fail. The experiments designed via this method fully constrain the model output dynamics to within experimentally resolvable limits. The method is effective for highly uncertain biological systems characterized by deterministic mathematical models with limited data sets. Also, it is highly modular and can be modified to include a variety of methodologies such as input design and model discrimination.

  19. Integrating psychology within the globalizing world: a requiem to the post-modernist experiment with Wissenschaft.

    2009-03-01

    Since the new beginning in 2007 of Integrative Psychological & Behavioral Science we have brought out to the open both the reasons why the ever-widening research enterprise in psychology has largely failed to produce general knowledge, and to point to promising new directions in the field. The post-modernist turn in psychology is now over, and it is an interesting task to return to creating a universal science of psychology that is context-sensitive, and culture-inclusive. The latter goal entails a renewed focus upon qualitative analyses of time-based processes, close attention to the phenomena under study, and systematic (single-system-based-usually labeled idiographic) focus in empirical investigations. Through these three pathways centrality of human experiencing of culturally constructed worlds is restored as the core of psychological science. Universal principles are evident in each and every single case. Transcending post-modernist deconstruction of science happens through active international participation and a renewed focus on creating general theories. Contemporary psychology is global in ways that no longer can any country's socio-political world view dominate the field. Such international equality of contributions grants innovation of the core of the discipline, and safeguards it against assuming any single cultural myth-story as the axiomatic basis for the discipline.

  20. Building collaboration through shared actions: The experience of the Global Network for Disaster Reduction

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available This article asks how the emergent Global Network for Disaster Reduction has built collaboration and impact. Observation of the network’s journey nuanced the researcher’s initial hypothesis in marked ways. A ‘reflective practitioner’ perspective is adopted, locating action within two relevant theoretical frameworks to aid understanding and define future progress. Development showed an early emphasis on a ‘community of practice’ model. However, this appeared ineffective in creating the intended collaboration and led to the recognition of the power of shared action. This observation is framed within the thinking of Freire (1996 on action and reflection as a means of empowerment. The political dimension of the network’s activity is recognised, and is related to Gaventa’s (1980 thinking on the creation of political space. The article attempts to show that combining cycles of action and reflection in the network’s activity (i.e. creating a practitioner focus with a wider investigation of relevant literature and thinking can be helpful in framing understanding and determining future strategy. It concludes by suggesting that a proposed framework of ‘communities of praxis’ may have a broader application in the development of networks.

  1. Action modulated cognition: the influence of sensori-motor experience on the global processing bias.

    Whether we are aware of it or not, cognition is inherently biased. Researchers have attempted to modulate these biases using prism adaptation in both healthy and patient populations. Recent research suggests that prisms themselves might not be necessary; simply interacting with one side of space can produce similar effects (Dupierrix, Alleysson, Ohlmann and Chokron (2008). Brain Research, 1214, 127-135). Here we tested whether sensori-motor interaction with the environment affects aspects of cognition that should at first glance appear to be unrelated. While previous research involved tasks that were largely directional in nature (e.g., line bisection), we chose a task without a directional component, the hierarchical figures task (Navon, (1977). Cognitive Psychology, 9, 353-383). In a sample of healthy young adults, we found that after 5min of lateralized pointing (pointing solely to the left or right side of space), performance on the hierarchical figures task varied significantly as a function of pointing direction: interference from irrelevant global information increased after interacting with the left side of space and decreased after interacting with the right side of space. We discuss the results in relation to a "hemispheric imbalance" hypothesis. Our findings demonstrate that cognition can be readily influenced by interactions with the environment even without artificially distorting normal perceptuo-motor relationships.

    As extreme climate events such as precipitation driven flooding, storms and droughts are increasingly devastating, assessing impacts accurately becomes critically important in guiding decisions and investments on disaster risk reduction. Capturing disaster impacts includes not only quantitative information such as the economic and human effects but also the determination of where and when the impacts occurred. Among the most commonly used impact indicators are the number of deaths and the number of people affected or homeless, and the economic damages. Unfortunately, these figures are typically used in their raw form and conclusions are drawn without due consideration to denominators. For example, key parameters such as the population base or the size of the region affected are often not factored in when judging the severity of the event or calculating increases or decreases in an indicator. To increase the meaningfulness and comparability of disaster impacts across time and space, however, it is important to mathematically standardize indicators and utilize common denominators such as number of population exposed, area affected, GDP, and so forth. Geospatial techniques such as geo-referencing and spatial overlays are coming into greater use to facilitate this process. In 2013, EM-DAT, one of the main providers of global disaster impact data, launched an effort to enhance its contents through spatial analyses. The challenge was to develop a sustainable methodology and protocol for a large dataset and to systematically collect and enter geocoded profiles for each event that is registered in EM-DAT. Along with specialists in geography from different institutions EM-DAT launched an effort to geocode each disaster event working backwards in time starting from the most recent. For geo-referencing purposes, EM-DAT requires a standardized dataset of sub-national administrative boundaries. Though a number of such initiatives exist, the Food and Agriculture Organization

  4. Modeling experience curves in MERGE (model for evaluating regional and global effects)

    2005-11-01

    The Swiss National Centre of Competence in Research on Climate aims to explore the predictability, variability, and risk of climate change. The Paul Scherrer Institute, which is involved in this program, uses integrated assessment models to simulate policies for climate-change mitigation under uncertainty. We report here selected results of the model for evaluating the regional and global effects (MERGEs) of greenhouse-gas emissions with endogenous technological learning (ETL), known as MERGE-ETL. The novelty of the approach is the application of an heuristic algorithm to solve the non-linear and non-convex MERGE problem where 'learning-by-doing' is adopted for a set of energy technologies. The study presents numerical examples showing the implications of endogenous-learning for the timing of carbon-abatement that stabilizes carbon concentrations (e.g. at 550 ppmv), as well as the implications of this in terms of cost/benefit (C/B) analysis. The endogenous-learning formulation is contrasted with the version of the model without ETL. The improved methodology indicates a potential for significant reduction in carbon-abatement cost and economic losses. The method, which is basically in favor of late actions in abatement, implicitly assumes early R and D support and learning investments in carbon-free systems to help these new technologies follow their learning curves. The endogenous treatment of learning already shows significant reductions of carbon emissions in the baseline case and indicates that low-carbon concentrations and improved environmental performance can be obtained when policies are followed that compensate for externalities related to climate change. More precisely, MERGE-ETL gives C/B-optimal carbon-emission trajectories near the 590-ppmv-concentration level. Moreover, the imposition of constraints on the rate of temperature change (e.g. 0.21{sup o}C per decade) demands early actions in carbon mitigation. (author)

    Full Text Available The article considers main measures of the financial policy realised in the countries of the world, in particular, Europe, USA, China and Japan, directed at prevention and liquidation of consequences of crisis phenomena of the world economy. It considers programmes of support of economy and financial sector of different countries adopted during the period of the world financial crisis of 2007 – 2009. It marks out that an important element of successful realisation of anti-crisis measures is a correct co-ordination of the budget and tax policy and money and loan policy. It positively marks out experience of application of active arbitrary stimulating policy under crisis conditions. In view of increase of efficiency of macro-economic management an important task of the future would be improvement of anti-crisis mechanisms with consideration of their influence upon short-term dynamics and long-term growth. The conducted analysis allows making a conclusion that mistakes of the financial policy are one of the main reasons of overheating the world economy, while analysis and use of experience of the leading countries of the world would allow increase of quality of the financial policy, directed at reduction of crisis vulnerability.

    The Global Ozone Monitoring Experiment (GOME) was launched on 21 April 1995 as one of six scientific instruments on board the second European remote sensing satellite (ERS-2) of the ESA. The investigations presented here aimed at assessing and improving the accuracy of the GOME measurements of sun-standardized and absolute radiation density and the derived data products. For this purpose, the GOME data were compared with measurements pf terrestrial, airborne and satellite-borne systems. For scientific reasons, the measurements will focus on the medium and high latitudes of both hemispheres, although equatorial regions were investigated as well. In the first stage, operational data products of GOME were validated, i.e. radiation measurements (spectra, level1 product) and trace gas column densities (level2 product). [German] Am 21. April 1995 wurde das Global Ozone Monitoring Experiment (GOME) als eines von insgesamt sechs wissenschaftlichen Instrumenten an Bord des zweiten europaeischen Fernerkundungssatelliten (ERS-2) der ESA ins All gebracht. Das Ziel dieses Vorhabens ist es, die Genauigkeit der von GOME durchgefuehrten Messungen von sonnennormierter und absoluter Strahlungsdichte sowie der aus ihnen abgeleiteten Datenprodukte zu bewerten und zu verbessern. Dazu sollten die GOME-Daten mit Messungen von boden-, flugzeug- und satellitengestuetzten Systemen verglichen werden. Aus wissenschaftlichen Gruenden wird der Schwerpunkt auf Messungen bei mittleren und hohen Breitengraden in beiden Hemisphaeren liegen. Jedoch wurden im Laufe des Projektzeitraumes auch Regionen in Aequatornaehe untersucht. Im ersten Schritt sollen operationelle Datenprodukte von GOME validiert werden. Dieses sind Strahlungsmessungen (Spektren, Level1-Produkt) und Spurengas-Saeulendichten (Level2-Produkt). (orig.)

    This paper presents an overview of recent experimental and numerical investigations on industrial railway brakes. The goal of the present study is to discuss the relevance of the mechanical modeling strategy for squeal prediction. Specific experimental set-ups based on transient and controlled braking tests are designed for this purpose. Measurements are performed on it to investigate the dynamic behavior of TGV squeal noise and its squeal characterization through experiments. It will be demonstrated that it is possible to build consistent and efficient finite element models to simulate squeal events in TGV brake systems. The numerical strategy will be presented, including not only the modeling of the TGV brake system and the stability analysis, but also the transient nonlinear dynamic and computational process based on efficient reduced basis. This complete numerical strategy allows us to perform relevance squeal prediction on industrial railway brakes. This study comes within the scope of a research program AcouFren that is supported by ADEME (Agence De l'Environnement et de la Maîtrise de l'Energie) concerning the reduction of the squeal noise generated by high power railway disc brakes. experiments with an evolution of the rotational speed of the disc: these tests are called "transient braking tests" and correspond to real braking tests, experiments with a controlled steady rotational speed (i.e. dynamic fluctuations in rotational speed are not significant): these tests are called "controlled braking tests". In the present study, the Continuous Wavelet Transform (CWT) [20] is used to study the time-history responses of the TGV brake system. So, a brief basic theory of the wavelet analysis that transforms a signal into wavelets that are well localized both in frequency and time is presented in this part of the paper. Considering a function f(t), the associated Continuous Wavelet Transform (CWT) corresponds to a wavelet transform given by W(a,b

    Switzer, Eric R

    2014-01-01

    Spectral measurements of the 21 cm monopole background have the promise of revealing the bulk energetic properties and ionization state of our universe from z ~ 6-30. Synchrotron foregrounds are orders of magnitude larger than the cosmological signal, and are the principal challenge faced by these experiments. While synchrotron radiation is thought to be spectrally smooth and described by relatively few degrees of freedom, the instrumental response to bright foregrounds may be much more complex. To deal with such complexities, we develop an approach that discovers contaminated spectral modes using spatial fluctuations of the measured data. This approach exploits the fact that foregrounds vary across the sky while the signal does not. The discovered modes are projected out of each line-of-sight of a data cube. An angular weighting then optimizes the cosmological signal amplitude estimate by giving preference to lower-noise regions. Using this method, we show that it is essential for the passband to be stable t...

    Drowning is the commonest cause of injury-related deaths among under-five children worldwide, and 95% of deaths occur in low- and middle-income countries (LMICs) where there are implementation gaps in the drowning prevention interventions. This article reviews common interventions for drowning prevention, introduces a framework for effective implementation of such interventions, and describes the Saving of Lives from Drowning (SoLiD) Project in Bangladesh, which is based on this framework. A review of the systematic reviews on drowning interventions was conducted, and original research articles were pulled and summarized into broad prevention categories. The implementation framework builds upon two existing frameworks and categorizes the implementing process for drowning prevention interventions into four phases: planning, engaging, executing, and evaluating. Eleven key characteristics are mapped in these phases. The framework was applied to drowning prevention projects that have been undertaken in some LMICs to illustrate major challenges to implementation. The implementation process for the SoLiD Project in Bangladesh is used as an example to illustrate the practical utilization of the framework. Drowning interventions, such as pool fencing and covering of water hazards, are effective in high-income countries; however, most of these interventions have not been tested in LMICs. The critical components of the four phases of implementing drowning prevention interventions may include: (i) planning-global funding, political will, scale, sustainability, and capacity building; (ii) engaging-coordination, involvement of appropriate individuals; (iii) executing-focused action, multisectoral actions, quality of execution; and (iv) evaluating-rigorous monitoring and evaluation. Some of the challenges to implementing drowning prevention interventions in LMICs include insufficient funds, lack of technical capacity, and limited coordination among stakeholders and implementers

    Many approaches and efforts have been used to better understand chronic diseases worldwide. Yet, little is known about the meaning of living with chronic illness under the pressures of globalization and neoliberal ideologies. Through Freire's participatory educational method, this article presents an innovative approach to understanding the multiple dimensions of living with chronic illness. In this way, we hope to use an innovative approach to address the impact of globalization on the daily life of chronically ill people and thus expand to the body of knowledge on nursing. This article uses Freire's participatory educational method to understand the multiple dimensions of living with chronic illness. This qualitative study follows an interpretive inquiry approach and uses a critical hermeneutic phenomenological method and critical research methodologies. Five participants were recruited for this participatory educational activity. Data collection methods included digitally recorded semistructured individual interviews and a Freire's participatory educational method session. Data analysis included a thematic analysis. Participants reported lacking adequate access to healthcare services because of insurance policies; a general perception that they were an unwanted burden on the healthcare system; and a general lack of government support, advocacy, and political interest. This research activity assisted participants to gain a new critical perspective about the condition of others with chronic diseases and thus provided an enlightening opportunity to learn about the illnesses and experiences of others and to realize that others experienced the same oppression from the healthcare system. Participants became agents of change within their own families and communities. Chronic diseases cause many economic and social consequences in their victims. These findings urge us to move from merely acknowledging the difficulties of people who live with chronic illness in an age of

    The Global Feature Extractor (gFEX) module is a component of the Level I trigger system for the ATLAS experiment planned for installation during the Phase I upgrade in 2018. This unique single ATCA board with multiple high speed processors on board will receive coarse-granularity information from all the ATLAS calorimeters enabling the identification in real time of large radius jets for capturing Lorentz-boosted objects such as top quarks, Higgs, Z and W bosons. The gFEX architecture is also suitable for the calculation of global event variables such as missing transverse energy, centrality for heavy ion collisions and event-by-event pile-up subtraction. gFEX will use 3 processor Xilinx Ultra-scale FPGAs for data processing and one single system-on-chip processor, ZYNQ, for configuring all the processor FPGAs and monitoring the board status. The current pre-prototype board which includes one ZYNQ and one Vertex-7 FPGA has been designed for testing and verification. The design of the final gFEX module as well...

    The data sets on this compact disc are a compilation of several geographic reference data sets of interest to the global-change research community. The data sets were chosen with input from the Global Energy and Water Cycle Experiment (GEWEX) Continental-Scale International Project (GCIP) Data Committee and the GCIP Hydrometeorology and Atmospheric Subpanels. The data sets include: locations and periods of record for stream gages, reservoir gages, and meteorological stations; a 500-meter-resolution digital elevation model; grid-node locations for the Eta numerical weather-prediction model; and digital map data sets of geology, land use, streams, large reservoirs, average annual runoff, average annual precipitation, average annual temperature, average annual heating and cooling degree days, hydrologic units, and state and county boundaries. Also included are digital index maps for LANDSAT scenes, and for the U.S. Geological Survey 1:250,000, 1:100,000, and 1:24,000-scale map series. Most of the data sets cover the conterminous United States; the digital elevation model also includes part of southern Canada. The stream and reservoir gage and meteorological station files cover all states having area within the Mississippi River Basin plus that part of the Mississippi River Basin lying within Canada. Several data-base retrievals were processed by state, therefore many sites outside the Mississippi River Basin are included.

    The solution of the energy-balance model of the Earth's global climate proposed in Ref. [1] is compared with well-known experimental data on the palaeotemperature evolution of Earth's surface over past 420 kyr and 740 kyr obtained in the framework of Antarctic projects the EPICA Dome C and Vostok. The Solar-Earth mechanism of anomalous temperature jumps observed in the EPICA Dome C and Vostok experiments and its relation with the "order-chaos" transitions in convection evolution in the liquid Earth core responsible to the mechanism of the Earth magnetic field inversions was discussed. The stabilizing role of the slow nuclear burning on the boundary of the liquid and solid phases of the Earth's core (georeactor with power of 30 TW) for convection evolution in the liquid Earth's core and hence in the Earth's magnetic field evolution is pointed out.

  16. Conceptual Change regarding middle school students' experience with Global Climate Change

    Given the complexity of the science involving climate change (IPCC, 2007), its lack of curricular focus within US K-12 schooling (Golden, 2009), and the difficulty in effecting conceptual change in science (Vosniadou, 2007), we sought to research middle school students' conceptions about climate change, in addition to how those conceptions changed during and as a result of a deliberately designed global climate change (GCC) unit. In a sixth grade classroom, a unit was designed which incorporated Argumentation-Driven Inquiry (Sampson & Grooms, 2010). That is, students were assigned to groups and asked to make sense of standard GCC data such as paleoclimate data from ice cores, direct temperature measurement, and Keeling curves, in addition to learning about the greenhouse effect in a modeling lesson (Hocking, et al, 1993). The students were then challenged, in groups, to create, on whiteboards, explanations and defend these explanations to and with their peers. They did two iterations of this argumentation. The first iteration focused on the simple identification of climate change patterns. The second focused on developing causal explanations for those patterns. After two rounds of such argumentation, the students were then asked to write (individually) a "final" argument which accounted for the given data. Interview and written data were analyzed prior to the given unit, during it, and after it, in order to capture complicated nuance that might escape detection by simpler research means such as surveys. Several findings emerged which promised to be of interest to climate change educators. The first is that many students tended to "know" many "facts" about climate change, but were unable to connect these disparate facts in any meaningful ways. A second finding is that while no students changed their entire belief systems, even after a robust unit which would seemingly challenge such, each student engaged did indeed modify the manner in which they discussed the

  17. Erasing the Variable: Empirical Foreground Discovery for Global 21 cm Spectrum Experiments

    2014-01-01

    Spectral measurements of the 21 cm monopole background have the promise of revealing the bulk energetic properties and ionization state of our universe from z approx. 6 - 30. Synchrotron foregrounds are orders of magnitude larger than the cosmological signal, and are the principal challenge faced by these experiments. While synchrotron radiation is thought to be spectrally smooth and described by relatively few degrees of freedom, the instrumental response to bright foregrounds may be much more complex. To deal with such complexities, we develop an approach that discovers contaminated spectral modes using spatial fluctuations of the measured data. This approach exploits the fact that foregrounds vary across the sky while the signal does not. The discovered modes are projected out of each line-of-sight of a data cube. An angular weighting then optimizes the cosmological signal amplitude estimate by giving preference to lower-noise regions. Using this method, we show that it is essential for the passband to be stable to at least approx. 10(exp -4). In contrast, the constraints on the spectral smoothness of the absolute calibration are mainly aesthetic if one is able to take advantage of spatial information. To the extent it is understood, controlling polarization to intensity leakage at the approx. 10(exp -2) level will also be essential to rejecting Faraday rotation of the polarized synchrotron emission.

    2017-08-01

    The transfer of experiences gained after prehospital medical responses to major incidents has largely been nonsystematic, and better-structured reporting methods have been advocated. A consensus-based template was recently created and implemented as an open-access website. This qualitative study assessed the feasibility of using the template and reporting site. Informants who had used or who had been asked to use the template were interviewed. The semi-structured interviews were transcribed verbatim, and the transcripts were analyzed by using an inductive approach based on grounded theory methodology. The major theme identified was a need for "defining purpose" as explained by the minor themes "relevance," "scope," "resources," and "usefulness." Informants reported that the template content needed to be revised and that the scope and rationale behind each question should be conveyed to the user. Resources necessary for reporting and clarity regarding the aim and outcome also need to be communicated to users and policy-makers. The interface between informants and the template is critical. Informants considered the template and website useful but reported that the workload exceeded their expectations. Despite pilot testing of the template before implementation, early revision of the template is recommended. (Disaster Med Public Health Preparedness. 2017;11:403-406).

  1. Saliva sampling in global clinical studies: the impact of low sampling volume on performance of DNA in downstream genotyping experiments

    Science.gov (United States)

    2013-01-01

    Background The collection of viable DNA samples is an essential element of any genetics research programme. Biological samples for DNA purification are now routinely collected in many studies with a variety of sampling methods available. Initial observation in this study suggested a reduced genotyping success rate of some saliva derived DNA samples when compared to blood derived DNA samples prompting further investigation. Methods Genotyping success rate was investigated to assess the suitability of using saliva samples in future safety and efficacy pharmacogenetics experiments. The Oragene® OG-300 DNA Self-Collection kit was used to collect and extract DNA from saliva from 1468 subjects enrolled in global clinical studies. Statistical analysis evaluated the impact of saliva sample volume of collection on the quality, yield, concentration and performance of saliva DNA in genotyping assays. Results Across 13 global clinical studies that utilized the Oragene® OG-300 DNA Self-Collection kit there was variability in the volume of saliva sample collection with ~31% of participants providing 0.5 mL of saliva, rather than the recommended 2 mL. While the majority of saliva DNA samples provided high quality genotype data, collection of 0.5 mL volumes of saliva contributed to DNA samples being significantly less likely to pass genotyping quality control standards. Assessment of DNA sample characteristics that may influence genotyping outcomes indicated that saliva sample volume, DNA purity and turbidity were independently associated with sample genotype pass rate, but that saliva collection volume had the greatest effect. Conclusion When employing saliva sampling to obtain DNA, it is important to encourage all study participants to provide sufficient sample to minimize potential loss of data in downstream genotyping experiments.

    2015-08-01

    Full Text Available The Model for Prediction Across Scales (MPAS is a novel set of earth-system simulation components and consists of an atmospheric model, an ocean model and a land-ice model. Its distinct features are the use of unstructured Voronoi meshes and C-grid discretisation to address shortcomings of global models on regular grids and of limited area models nested in a forcing data set, with respect to parallel scalability, numerical accuracy and physical consistency. This makes MPAS a promising tool for conducting climate-related impact studies of, for example, land use changes in a consistent approach. Here, we present an in-depth evaluation of MPAS with regards to technical aspects of performing model runs and scalability for three medium-size meshes on four different High Performance Computing sites with different architectures and compilers. We uncover model limitations and identify new aspects for the model optimisation that are introduced by the use of unstructured Voronoi meshes. We further demonstrate the model performance of MPAS in terms of its capability to reproduce the dynamics of the West African Monsoon and its associated precipitation. Comparing 11 month runs for two meshes with observations and a Weather Research & Forecasting tool (WRF reference model, we show that MPAS can reproduce the atmospheric dynamics on global and local scales, but that further optimisation is required to address a precipitation excess for this region. Finally, we conduct extreme scaling tests on a global 3 km mesh with more than 65 million horizontal grid cells on up to half a million cores. We discuss necessary modifications of the model code to improve its parallel performance in general and specific to the HPC environment. We confirm good scaling (70 % parallel efficiency or better of the MPAS model and provide numbers on the computational requirements for experiments with the 3 km mesh. In doing so, we show that global, convection-resolving atmospheric

    Full Text Available International experiences are increasingly popular among medical students, but few have been rigorously evaluated. We used ESM to characterize the experience of medical students participating in the one-month University of Chicago Geographic Medicine Scholars Program (GMSP in Hyderabad, India. Participants wore watches programmed to randomly beep eight times daily, during the first and third weeks. When alerted, students reported their activity and rated their level of engagement and emotion in booklets. All 11 student participants responded to 59% of 816 alerts. 41% of beeps occurred during GMSP formal structured activities (i.e., lecture, clinic. Students reported structured activities to be more interesting (6.05 versus 4.14; P<0.001, more important to their future goals (6.48 versus 5.71; P<0.001, more challenging (3.75 versus 2.48; P<0.001, and more enjoyable (6.08 versus 5.36; P<0.001 than unstructured activities. Our results show that future global health efforts should augment the use of structured activities.

    We investigate a way one can achieve good spectral resolution in 2H MAS NMR experiments. The goal is to be able to distinguish between and study sites in various deuterated materials with small chemical shift dispersion. We show that the 2H MAS NMR spectra recorded during a spin-relaxation experiment are amenable to spectral decomposition because of the different evolution of spectral components during the relaxation delay. We verify that the results are robust by global least-square fitting of the spectral series both under the assumption of specific line shapes and without such assumptions (COmponent-REsolved spectroscopy, CORE). In addition, we investigate the reliability of the developed protocol by analyzing spectra simulated with different combinations of spectral parameters. The performance is demonstrated in a model material of deuterated poly(methacrylic acid) that contains two 2H spin populations with similar chemical shifts but different quadrupole splittings. In 2H-exchanged cellulose containing two 2H spin populations with very similar chemical shifts and quadrupole splittings, the method provides new site-selective information about the molecular dynamics.

    1996-10-01

    This article investigates through numerical experiments the controversial question of the impact of El Niño-Southern Oscillation (ENSO) phenomena on climate according to large-scale and regional-scale interhemispheric thermal contrast. Eight experiments (two considering only inversed Atlantic thermal anomalies and six combining ENSO warm phase with large-scale interhemispheric contrast and Atlantic anomaly patterns) were performed with the Météo-France atmospheric general circulation model. The definition of boundary conditions from observed composites and principal components is presented and preliminary results concerning the month of August, especially over West Africa and the equatorial Atlantic are discussed. Results are coherent with observations and show that interhemispheric and regional scale sea-surface-temperature anomaly (SST) patterns could significantly modulate the impact of ENSO phenomena: the impact of warm-phase ENSO, relative to the atmospheric model intercomparison project (AMIP) climatology, seems stronger when embedded in global and regional SSTA patterns representative of the post-1970 conditions [i.e. with temperatures warmer (colder) than the long-term mean in the southern hemisphere (northern hemisphere)]. Atlantic SSTAs may also play a significant role. Acknowledgements.

    2015-11-01

    Full Text Available Background: We present a literature review on trauma exposure and spirit possession in low- and middle-income countries (LMICs. Despite the World Health Organization's objective of culturally appropriate mental health care in the Mental Health Action Plan 2013–2020, and the recommendations of the Inter-Agency Standing Committee to consider local idioms of distress and to collaborate with local resources, this topic still receives very little attention. Pathological spirit possession is commonly defined as involuntary, uncontrollable, and occurring outside of ritual settings. It is often associated with stigmatization, suffering, and dysfunctional behavior. While spirit possession has been discussed as an idiom of distress in anthropological literature, recent quantitative studies have presented support for a strong relationship between traumatic experiences and pathological possession states. Objective: The aim of this review was to investigate this relationship systematically in LMICs, in view of the debate on how to address the mental health gap in LMICs. Methods: Twenty-one articles, published in peer-reviewed English-language journals between 1994 and 2013, were identified and analyzed with regard to prevalence of possessive trance disorders, patients’ sociodemographic characteristics, and its relation to traumatic experiences. Results: The review and analysis of 917 patients with symptoms of possessive trance disorders from 14 LMICs indicated that it is a phenomenon occurring worldwide and with global relevance. This literature review suggests a strong relationship between trauma exposure and spirit possession with high prevalence rates found especially in postwar areas in African countries. Conclusions: More attention for possessive trance disorders in mental health and psychosocial intervention programs in humanitarian emergency settings as well as in societies in transition in LMICs is needed and justified by the results of this

    A novel meta-heuristic approach for minimizing nonlinear constrained problems is proposed, which offers tolerance information during the search for the global optimum. The method is based on the concept of design and analysis of computer experiments combined with a novel two phase design augmentation (DACEDA), which models the entire merit space using a Gaussian process, with iteratively increased resolution around the optimum. The algorithm is introduced through a series of cases studies with increasing complexity for optimizing uniformity of a short-wave infrared (SWIR) hyperspectral imaging (HSI) illumination system (IS). The method is first demonstrated for a two-dimensional problem consisting of the positioning of analytical isotropic point sources. The method is further applied to two-dimensional (2D) and five-dimensional (5D) SWIR HSI IS versions using close- and far-field measured source models applied within the non-sequential ray-tracing software FRED, including inherent stochastic noise. The proposed method is compared to other heuristic approaches such as simplex and simulated annealing (SA). It is shown that DACEDA converges towards a minimum with 1 % improvement compared to simplex and SA, and more importantly requiring only half the number of simulations. Finally, a concurrent tolerance analysis is done within DACEDA for to the five-dimensional case such that further simulations are not required.

    2016-10-01

    This study investigates the dynamics of non-isothermal swirling jets undergoing vortex breakdown, with an emphasis on helical coherent structures. It is proposed that the dominant helical coherent structure can be suppressed by heating the recirculation bubble. This proposition is assessed with stereo Particle Image Velocimetry (PIV) measurements of the breakdown region of isothermal and heated swirling jets. The coherent kinetic energy of the dominant helical structure was derived from PIV snapshots via proper orthogonal decomposition. For one set of experimental parameters, mild heating is found to increase the energy content of the dominant helical mode. Strong heating leads to a reduction by 30% of the coherent structures energy. For a second set of experimental parameters, no alteration of the dominant coherent structure is detectable. Local linear stability analysis of the time-averaged velocity fields shows that the key difference between the two configurations is the density ratio at the respective wavemaker location. A density ratio of approximately 0.8 is found to correlate to a suppression of the global mode in the experiments. A parametric study with model density and velocity profiles indicates the most important parameters that govern the local absolute growth rate: the density ratio and the relative position of the density profiles and the inner shear layer.

    International outreach by schools and colleges of pharmacy is increasing. In this paper, we provide current practice guidelines to establish and maintain successful global/international advanced pharmacy practice experiences (G/I APPEs) with specific recommendations for home/host country and host site/institution. The paper is based on a literature review (2000-2014) in databases and Internet searches with specific keywords or terms. Educational documents such as syllabi and memoranda of understanding (MoUs) from pharmacy programs were also examined. In addition, a preliminary draft was developed and the findings and recommendations were reviewed in a 90-minute roundtable discussion at the 2014 American Association of Colleges of Pharmacy Annual Meeting. Recommendations for the host country include travel considerations (eg, passport, visa, air travel), safety, housing, transportation, travel alerts and warnings, health issues, and financial considerations. For the home country, considerations for establishment of G/I APPE site (eg, vetting process, MoU, site expectations) are described. The paper is a resource for development of new G/I APPEs and provides guidance for continuous quality improvement of partnerships focusing on G/I pharmacy education.

    Full Text Available We investigate the effect of using three different cross section data sets on ozone profile retrievals from Global Ozone Monitoring Experiment (GOME ultraviolet measurements (289–307 nm, 326–337 nm. These include Bass-Paur, Brion, and GOME flight model cross sections (references below. Using different cross sections can significantly affect the retrievals, by up to 12 Dobson Units (DU, 1 DU=2.69×1016 molecules cm−2 in total column ozone, up to 10 DU in tropospheric column ozone, and up to 100% in retrieved ozone values for individual atmospheric layers. Compared to using the Bass-Paur and GOME flight model cross sections, using the Brion cross sections not only reduces fitting residuals by 15–60% in the Huggins bands, but also improves retrievals, especially in the troposphere, as seen from validation against ozonesonde measurements. Therefore, we recommend using the Brion cross section for ozone profile retrievals from ultraviolet measurements. The total column ozone retrieved using the GOME flight model cross sections is systematically lower, by 7–10 DU, than that retrieved using the Brion and Bass-Paur cross sections and is also systematically lower than Total Ozone Mapping Spectrometer (TOMS observations. This study demonstrates the need for improved ozone cross section measurements in the ultraviolet to improve profile retrievals of this key atmospheric constituent.

    In 2009, Blue Cross Blue Shield of Massachusetts implemented a global budget-based payment system, the Alternative Quality Contract (AQC), in which provider groups assumed accountability for spending. We investigate the impact of global budgets on the utilization of prescription drugs and related expenditures. Our analyses indicate no statistically significant evidence that the AQC reduced the use of drugs. Although the impact may change over time, early evidence suggests that it is premature to conclude that global budget systems may reduce access to medications. PMID:25500751

  4. What do moisture recycling estimates tell? Lessons from an extreme global land-cover change model experiment

    Directory of Open Access Journals (Sweden)

    H. F. Goessling

    2011-04-01

    Full Text Available Moisture evaporated from the continents (recycled moisture contributes up to 80% to the total atmospheric moisture content and, hence, precipitation in some regions. Recycling estimates are traditionally used to indicate a region's rainfall-dependence on land-surface evaporation. Accordingly, recycling estimates are employed to deduce the hydrological consequences of land-cover change. However, moisture is not a passive but an active constituent of the atmosphere. Recent studies indicate that at small scales (up to 1000 km local to regional evaporation-precipitation coupling by far dominates the atmospheric precipitation response, while the water-balance effect from moisture recycling in the traditional sense seems to be of minor importance. The value of moisture recycling estimates as indicator for consequences of land-cover change is therefore questionable. However, since atmospheric moisture is still subject to mass conservation, the relevance of moisture recycling may come into play at the continental scale.

    To explore the relevance of recycling estimates regarding land-cover change at the continental scale, we conduct two global experiments with an atmospheric general circulation model: (I with present-day conditions and (II with extreme land-cover change conditions, namely with totally suppressed continental evaporation. Using the simulated fields of moisture, wind, and evaporation from the present-day experiment, we quantify continental moisture recycling with a vertically integrating tracing scheme. We then compare the computed recycling patterns with the hydrological changes that follow the suppression of continental evaporation.

    While under present-day conditions the fraction of recycled moisture increases from continental upstream to downstream regions with respect to the prevailing winds, the suppression of continental evaporation leads to severe precipitation loss in almost all continental regions, no matter if

  6. Blueprint and First Experiences Bridging Hardware Virtualization and Global Grids for Advanced Scientific Computing: Designing and Building a Global Edge Services Framework (ESF) for OSG, EGEE, and LCG

    CERN Document Server

    Rana, A S; Vaniachine, A; Wurthwein, F; Foster, I; Sotomayor, B; Freeman, T

    2006-01-01

    We report on first experiences with building and operating an edge services framework (ESF) based on Xen virtual machines instantiated via the workspace service in Globus toolkit, and developed as a joint project between EGEE, LCG, and OSG. Many computing facilities are architected with their compute and storage clusters behind firewalls. Edge services (ES) are instantiated on a small set of gateways to provide access to these clusters via standard grid interfaces. Experience on EGEE, LCG, and OSG has shown that at least two issues are of critical importance when designing an infrastructure in support of ES. The first concerns ES configuration. It is impractical to assume that each virtual organization (VO) using a facility will employ the same ES configuration, or that different configurations will coexist easily. Even within a VO, it should be possible to run different versions of the same ES simultaneously. The second issue concerns resource allocation: it is essential that an ESF be able to effectively gu...

  7. Globalization and Medical Tourism: The North American Experience; Comment on “Patient Mobility in the Global Marketplace: A Multidisciplinary Perspective”

    Directory of Open Access Journals (Sweden)

    Arturo Vargas Bustamante

    2014-06-01

    Full Text Available Neil Lunt and Russel Mannion provide an overview of the current state of the medical tourism literature and propose areas for future research in health policy and management. The authors also identify the main unanswered questions in this field ranging from the real size of the medical tourism market to the particular health profiles of transnational patients. In addition, they highlight unexplored areas of research from health economics, ethics, policy and management perspectives. To this very insightful editorial I would add the international trade perspective. While globalization has permeated labor and capital, services such as healthcare are still highly regulated by governments, constrained to regional or national borders and protected by organized interests. Heterogeneity of healthcare regulations and lack of cross-country reciprocity agreements act as barriers to the development of more widespread and dynamic medical tourism markets. To picture these barriers to transnational health services I use evidence from North America, identifying different “pull and push factors” for medical tourist in this region, discussing how economic integration and healthcare reform might shift the incentives to utilize healthcare abroad.

  8. Experience-Based and Description-Based Perceptions of Long-Term Risk. Why Global Warming does not Scare us (Yet)

    Energy Technology Data Exchange (ETDEWEB)

    Weber, E.U. [Center for Research on Environmental Decisions, Columbia University, New York (United States)

    2006-07-15

    It should come as no surprise that the governments and citizenries of many countries show little concern about climate change and its consequences. Behavioral decision research over the last 30 years provides a series of lessons about the importance of affect in perceptions of risk and in decisions to take actions that reduce or manage perceived risks. Evidence from a range of domains suggests that worry drives risk management decisions. When people fail to be alarmed about a risk or hazard, they do not take precautions. Recent personal experience strongly influences the evaluation of a risky option. Low-probability events generate less concern than their probability warrants on average, but more concern than they deserve in those rare instances when they do occur. Personal experience with noticeable and serious consequences of global warming is still rare in many regions of the world. When people base their decisions on statistical descriptions about a hazard provided by others, characteristics of the hazard identified as psychological risk dimensions predict differences in alarm or worry across different classes of risk. The time-delayed, abstract, and often statistical nature of the risks of global warming does not evoke strong visceral reactions. These results suggest that we should find ways to evoke visceral reactions towards the risk of global warming, perhaps by simulations of its concrete future consequences for people's home or other regions they visit or value. Increased concern about global warming needs to solicited carefully, however, to prevent a decrease in concern about other relevant risks. The generation of worry or concern about global warming may be a necessary but not sufficient condition for desirable or appropriate protective or mitigating behavior on part of the general public.

    Reed, P. M.

    2011-12-01

    Global scale issues such as population growth, changing land-use, and climate change place our natural resources at the center of focus for a broad range of interdependent science, engineering, and policy problems. Our ability to mitigate and adapt to the accelerating rate of environmental change is critically dependent on our ability to observe and predict the natural, built, and social systems that define sustainability at the global scale. Despite the risks and challenges posed by global change, we are faced with critical risks to our ability to maintain and improve long term space-based observations of these changes. Despite consensus agreement on the critical importance of space-based Earth science, the fundamental challenge remains: How should we manage the severe tradeoffs and design challenges posed by maximizing the value of existing and proposed spaced-based Earth observation systems? Addressing this question requires transformative innovations in the design and management of spaced-based Earth observation systems that effectively take advantage of massively parallel computing architectures to enable the discovery and exploitation of critical mission tradeoffs using high-resolution space-based observation system simulation events (OSSEs) that simulate the global water cycle data that would result from sensing innovations and evaluates their merit with carefully constructed prediction and management benchmarks.

    1981-01-01

    By examining the vertical structure of the low order spherical harmonics of the divergence and vorticity fields, the relative contribution of tropical and monsoonal circulations upon the global wind fields was estimated. This indicates that the overall flow over North America and the Pacific between January and February is quite distinct both in the lower and upper troposphere. In these longitudes there is a stronger tropical overturning and subtropical jet stream in January than February. The divergent flow reversed between 850 and 200 mb. Poleward rotational flow at upper levels is associated with an equatorward rotational flow at low levels. This suggests that the monsoon and other tropical circulations project more amplitude upon low order (global scale) representations of the flow than do the typical midlatitude circulations and that their structures show conspicuous changes on a time scale of a week or less.

    Most state-of-the art global coupled models simulate a weakening of the Atlantic meridional overturning circulation (MOC) in climate change scenarios but the mechanisms leading to this weakening are still being debated. The third version of the CNRM (Centre National de Recherches Meteorologiques) global atmosphere-ocean-sea ice coupled model (CNRM-CM3) was used to conduct climate change experiments for the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4). The analysis of the A1B scenario experiment shows that global warming leads to a slowdown of North Atlantic deep ocean convection and thermohaline circulation south of Iceland. This slowdown is triggered by a freshening of the Arctic Ocean and an increase in freshwater outflow through Fram Strait. Sea ice melting in the Barents Sea induces a local amplification of the surface warming, which enhances the cyclonic atmospheric circulation around Spitzberg. This anti-clockwise circulation forces an increase in Fram Strait outflow and a simultaneous increase in ocean transport of warm waters toward the Barents Sea, favouring further sea ice melting and surface warming in the Barents Sea. Additionally, the retreat of sea ice allows more deep water formation north of Iceland and the thermohaline circulation strengthens there. The transport of warm and saline waters toward the Barents Sea is further enhanced, which constitutes a second positive feedback. (orig.)

    1999-12-20

    A network of small balloon-borne transponders which gather very high resolution wind and temperature data for use by modern numerical weather predication models has been proposed to improve the reliability of long-range weather forecasts. The global distribution of an array of such transponders is simulated using LLNL's atmospheric parcel transport model (GRANTOUR) with winds supplied by two different general circulation models. An initial study used winds from CCM3 with a horizontal resolution of about 3 degrees in latitude and longitude, and a second study used winds from NOGAPS with a 0.75 degree horizontal resolution. Results from both simulations show that reasonable global coverage can be attained by releasing balloons from an appropriate set of launch sites.

    The Global Feature Extractor (gFEX) module is a planned component of the Level 1 online trigger system for the ATLAS experiment planned for installation during the Phase I upgrade in 2018. This unique single electronics board with multiple high speed processors will receive coarse-granularity information from all the ATLAS calorimeters enabling the identification in real time of large-radius jets for capturing Lorentz-boosted objects such as top quarks, Higgs, $Z$ and $W$ bosons. The gFEX architecture also facilitates the calculation of global event variables such as missing transverse energy, centrality for heavy ion collisions, and event-by-event pile-up energy density. Details of the electronics architecture that provides these capabilities are presented, along with results of tests of the prototype systems now available. The status of the firmware algorithm design and implementation as well as monitoring capabilities are also presented.

    2013-12-01

    The public has access to a bewildering variety of climate change information. But there are no resources offering an accessible opportunity to listen to scientists communicating with each other about climate science. With access to 24 years of digital video archives of scientific presentations and discussions at small, interdisciplinary workshops with leading experts in global change science, AGCI (the Aspen Global Change Institute) saw an opportunity to fill that gap by using selected excerpts from this vast archive to engage public and educational interest in climate change. Our hypothesis is that offering people direct access to climate science discourse will stimulate curiosity leading to greater willingness to participate in further learning and dialogue about climate change. AGCI's NSF-funded project 'From the Horse's Mouth' (FTHM) is providing a way to test this hypothesis. FTHM is a website that combines short (2-8 min) video clips of scientists presenting and discussing their research with colleagues with enriching accessory materials targeted at the high school level of comprehension. The website offers a 'fly on the wall' insight into scientific communication about global change that is rarely experienced by non-scientists and that can be accessed anytime, anywhere, from classrooms to cafes. By removing the scientific process from a shroud of mystery and offering everyone an opportunity to listen in during scientific discourse, FTHM can help cultivate a sense of having a personal understanding of scientific information and thereby make a huge contribution to a more substantive and authentic climate literacy. Here we present successes, challenges, and complications in using first-hand scientific sources to build a bridge between formal and informal learning.

  1. Examining the social context in the caregiving experience: correlates of global self-esteem among adult daughter caregivers to an older parent with cancer.

    2009-10-01

    To examine the associations between various patient, disease, situation, and caregiver characteristics (organized by five conceptual domains) and global self-esteem among caregiver daughters to parents with cancer. Dyads comprised of 237 cancer outpatients and their adult caregiving daughter completed structured telephone interviews. Two of the five domains of potential correlates significantly predicted caregiving daughters' global self-esteem-daughters' sociodemographics and constraints on/facilitators of caregiving. Daughters' overall sense of self-worth was directly correlated with their household income and inversely correlated with greater depressive affect and the number of patient needs for which someone else provided assistance. It was also correlated with the daughters' other role obligations. A higher sense of self-worth was associated with either being employed or having to care for a child/grandchild; a lower sense of self-worth was associated with having a spouse/partner. The present analysis documents the complexity of social connectedness, demonstrating that various role obligations contribute to caregiving daughters' global self-esteem in different ways. In the context of assuming cancer careprovision, daughters' existing repertoire of social roles may possibly mediate the stress associated with their care involvement or serve as a buffer against the strain of the caregiving experience.

    2012-08-01

    Full Text Available Open educational resources, institutional collaborations, and content reusability approaches have been quickly emerging to minimize the time and money spent on developing e-learning materials. Reusing content with reusable learning objects (RLOs is carving a new path for research on reusing and repurposing available high quality e-learning content. Prior research shows that this component-based approach best fits how educators prefer to access materials. In this paper, without arguing the merits and demerits of RLOs as a concept, the authors present an effective and affordable approach to creating e-learning materials with RLOs. The authors also present how they have implemented the proposed RLO approach in converting learning modules of the Global Academy for Extension Practice into multiple e-learning material formats.

    2015-03-01

    Full Text Available The article considers the main trends in the diversification of the global food system. The author proves that at the present time the dynamic development and globalization in the modern world economy require diversification of Belarusian agro-food complex in order to achieve its independence from crises, reduce risks of the external environment uncertainty, unforeseen circumstances (export embargoes and restrictions and changes in consumer preferences and, ultimately, boost competitiveness and strengthen economic immunity and stability. At the same time, the pressure of the abundant food supply in the world market segments, ensured by consumer demand, makes the manufacturers follow the principle “from fork to farm”. Thus, it is consumers’ preferences that are often drivers of contradictory and competing shifts in the transformation of food systems. The survey shows that two opposite driving forces – the consumers’ desire for ready-to-use food products with the deep level of processing and the growing elite interest in the natural healthy diet – determine the progressive development of productive forces in the agricultural complex in the direction of innovative search of diverse, adapted to consumer demand, high-tech schemes of production, processing and distribution of food. The classification of main consumer types helps substantiate the priority to develop new types of product subcomplexes. The ecological forms of agriculture have significant export potential and import substitution reserves in the Republic of Belarus and the Eurasian Economic Union as a whole. The author proposes a “road map” for the diversification of food production on the basis of organic (environmentally friendly agriculture. Its innovation is scientifically justified by the state large-scale economic, managerial and technological measures to develop a highly efficient organic sector of agricultural production in the republic

    Numerous studies have demonstrated that soil respiration rates increase under experimental warming, although the long-term, multiyear dynamics of this feedback are not well constrained. Less is known about the effects of single, punctuated events in combination with other longer-duration anthropogenic influences on the dynamics of soil carbon (C) loss. In 2012 and 2013, we assessed the effects of decadal-scale anthropogenic global change - warming, increased nitrogen (N) deposition, elevated carbon dioxide (CO2 ), and increased precipitation - on soil respiration rates in an annual-dominated Mediterranean grassland. We also investigated how controlled fire and an artificial wet-up event, in combination with exposure to the longer-duration anthropogenic global change factors, influenced the dynamics of C cycling in this system. Decade-duration surface soil warming (1-2 °C) had no effect on soil respiration rates, while +N addition and elevated CO2 concentrations increased growing-season soil CO2 efflux rates by increasing annual aboveground net primary production (NPP) and belowground fine root production, respectively. Low-intensity experimental fire significantly elevated soil CO2 efflux rates in the next growing season. Based on mixed-effects modeling and structural equation modeling, low-intensity fire increased growing-season soil respiration rates through a combination of three mechanisms: large increases in soil temperature (3-5 °C), significant increases in fine root production, and elevated aboveground NPP. Our study shows that in ecosystems where soil respiration has acclimated to moderate warming, further increases in soil temperature can stimulate greater soil CO2 efflux. We also demonstrate that punctuated short-duration events such as fire can influence soil C dynamics with implications for both the parameterization of earth system models (ESMs) and the implementation of climate change mitigation policies that involve land-sector C accounting.

    Responses of the Kuroshio Extension (KE) and its southern recirculation gyre (SRG) to global warming are investigated using CMIP5 experiments with a high-resolution climate model MIROC4h. The results show that MIROC4h well reproduces the essential features of the KE system and its low-frequency variations. In three-member-ensemble future climate experiments (with a medium mitigation emissions scenario RCP4.5), the strengths of the KE and its SRG increase, relative to the prescribed historical run with natural and anthropogenic forcing. By investigating the mechanism resulting in these variations of the KE and its SRG, it turns out that wind stress changes and ocean stratification changes both contribute to the enhancement of the KE and its SRG. Specifically, the wind stress changes increase upper ocean momentum in the SRG region. Meanwhile, the increased stratifications hinder the transfer of momentum from the upper ocean to the deeper ocean. Besides, the strengthened ocean stratification could enhance the eddy kinetic energy (EKE) in the downstream KE region, which can feedback to intensify the SRG. As a result, the strength of the SRG increases under global warming condition. Then the intensification of the SRG leads to large acceleration of the KE. Eventually, both the KE and its SRG intensify.

    In this work, the system design, integration, and wind tunnel experimental evaluation are presented for a bioinspired self-sensing intelligent composite unmanned aerial vehicle (UAV) wing. A total of 148 micro-sensors, including piezoelectric, strain, and temperature sensors, in the form of stretchable sensor networks are embedded in the layup of a composite wing in order to enable its self-sensing capabilities. Novel stochastic system identification techniques based on time series models and statistical parameter estimation are employed in order to accurately interpret the sensing data and extract real-time information on the coupled air flow-structural dynamics. Special emphasis is given to the wind tunnel experimental assessment under various flight conditions defined by multiple airspeeds and angles of attack. A novel modeling approach based on the recently introduced Vector-dependent Functionally Pooled (VFP) model structure is employed for the stochastic identification of the "global" coupled airflow-structural dynamics of the wing and their correlation with dynamic utter and stall. The obtained results demonstrate the successful system-level integration and effectiveness of the stochastic identification approach, thus opening new perspectives for the state sensing and awareness capabilities of the next generation of "fly-by-fee" UAVs.

    Full Text Available The countries in the world in the globalized era have faced heterogeneity in challenges in managing their growth factors as well as the stake holders of such growth profiles. The political and economic turmoil of the last two decades around the world have opened the eyes of the consumers, business houses and the governments of different countries to read and follow the economic events. The paper has tried to study the causal relation and interrelationships among different growth factors like the confidence levels of the consumers and business houses, inflation, unemployment like economic factors and governance like non-economic factors over a selection of 17 countries across all continents for the period 1996-2010. Because of limited sources of data we have applied the pooled regression technique to justify our study. Confidence levels of both the consumers and business houses cause the growth rates whereas governance causes growth only under pooled data. But for individual country data we observe that in majority of the countries there are absences of causalities between the variables. It has been observed that pooled annual growth rates of GDP of the countries are significantly related to the business and consumer confidence indexes, unemployment rate, debt ratio and overall governance indicators that shows improvement over the individual country analysis where in majority of the cases there is no significant factor for growth and confidence. By segregating the entire data the study find a few countries where a few variables like BCI, stock prices and governance make significant impact upon growth rates. In majority of the countries BCI is explained by CCI, Stock prices and governance while CCI is explained by stock prices, governance and debt ratio.

    The impact of climate warming on the seasonal variability of the Humboldt Current system ocean dynamics is investigated. The IPSL-CM4 large scale ocean circulation resulting from two contrasted climate scenarios, the so-called Preindustrial and quadrupling CO{sub 2}, are downscaled using an eddy-resolving regional ocean circulation model. The intense surface heating by the atmosphere in the quadrupling CO{sub 2} scenario leads to a strong increase of the surface density stratification, a thinner coastal jet, an enhanced Peru-Chile undercurrent, and an intensification of nearshore turbulence. Upwelling rates respond quasi-linearly to the change in wind stress associated with anthropogenic forcing, and show a moderate decrease in summer off Peru and a strong increase off Chile. Results from sensitivity experiments show that a 50% wind stress increase does not compensate for the surface warming resulting from heat flux forcing and that the associated mesoscale turbulence increase is a robust feature.

    Microbial gene expression was followed for 23 days within a mesocosm (M1) isolating 50 m3 of seawater and in the surrounding waters in the Nouméa lagoon, New Caledonia, in the southwest Pacific as part of the VAriability of vertical and tropHIc transfer of diazotroph derived N in the south wEst Pacific (VAHINE) experiment. The aim of VAHINE was to examine the fate of diazotroph-derived nitrogen (DDN) in a low-nutrient, low-chlorophyll ecosystem. On day 4 of the experiment, the mesocosm was fertilized with phosphate. In the lagoon, gene expression was dominated by the cyanobacterium Synechococcus, closely followed by Alphaproteobacteria. In contrast, drastic changes in the microbial community composition and transcriptional activity were triggered within the mesocosm within the first 4 days, with transcription bursts from different heterotrophic bacteria in rapid succession. The microbial composition and activity of the surrounding lagoon ecosystem appeared more stable, although following similar temporal trends as in M1. We detected significant gene expression from Chromerida in M1, as well as the Nouméa lagoon, suggesting these photoautotrophic alveolates were present in substantial numbers in the open water. Other groups contributing substantially to the metatranscriptome were affiliated with marine Euryarchaeota Candidatus Thalassoarchaea (inside and outside) and Myoviridae bacteriophages likely infecting Synechococcus, specifically inside M1. High transcript abundances for ammonium transporters and glutamine synthetase in many different taxa (e.g., Pelagibacteraceae, Synechococcus, Prochlorococcus, and Rhodobacteraceae) was consistent with the known preference of most bacteria for this nitrogen source. In contrast, Alteromonadaceae highly expressed urease genes; Rhodobacteraceae and Prochlorococcus showed some urease expression, too. Nitrate reductase transcripts were detected on day 10 very prominently in Synechococcus and in Halomonadaceae. Alkaline

    Intraspecific adaptation in Abies sachalinensis was examined using models based on long-term monitoring data gathered during a reciprocal transplant experiment with eight seed source populations and six transplantation sites along an altitudinal gradient. The consequence of local adaptation was evaluated by testing the home-site advantage for upslope and downslope transplants at five ages. The populations' fitness-linked trait was set as their productivity (tree height × survival rate) at each age. The effects of global warming were evaluated on the basis of the 36-year performance of downslope transplants. Evidence was found for adaptive genetic variation affecting both height and survival from an early age. Increasing the distance between seed source and planting site significantly reduced productivity for both upslope and downslope transplantation, demonstrating the existence of a significant home-site advantage. The decrease in productivity was most distinct for upslope transplantations, indicating strong local adaptation to high altitudes. Global warming is predicted to increase the productivity of high-altitude populations. However, owing to their existing local adaptation, all tested populations exhibited lower productivity under warming than demes that were optimal for the new climate. These negative predictions should be considered when planning the management of locally adapted plant species such as A. sachalinensis.

    Modeling studies have shown that nitrogen (N) strongly regulates ecosystem responses and feedback to climate warming. However, it remains unclear what mechanisms underlie N regulation of ecosystem-climate interactions. To examine N regulation of ecosystem feedback to climate change, we have conducted a warming and clipping experiment since November 1999 in a tallgrass prairie of the Great Plains, USA. Infrared heaters were used to elevate soil temperature by an average of 1.96 degrees C at a depth of 2.5 cm from 2000 to 2008. Yearly biomass clipping mimicked hay or biofuel feedstock harvest. We measured carbon (C) and N concentrations, estimated their content and C:N ratio in plant, root, litter, and soil pools. Warming significantly stimulated C storage in aboveground plant, root, and litter pools by 17%, 38%, and 29%, respectively, averaged over the nine years (all P warmed plots compared to the control plots, resulting primarily from increased dominance of C4 plants in the community. Clipping significantly decreased C and N storage in plant and litter pools (all P warming on either C or N pools over the nine years. Our results suggest that increased ecosystem nitrogen use efficiency via a shift in species composition toward C4 dominance rather than plant N uptake is a key mechanism underlying warming stimulation of plant biomass growth.

    Full Text Available The mid-Pliocene (3.3 to 3.0 million yr ago, a globally warm period before the Quaternary, is recently attracting attention as a new target for paleoclimate modelling and data-model synthesis. This paper reports set-ups and results of experiments proposed in Pliocene Model Intercomparison Project (PlioMIP using a global climate model, MRI-CGCM2.3. We conducted pre-industrial and mid-Pliocene runs by using the coupled atmosphere-ocean general circulation model (AOGCM and its atmospheric component (AGCM for the PlioMIP Experiments 2 and 1, respectively. In addition, we conducted two types of integrations in AOGCM simulation, with and without flux adjustments on sea surface. General characteristics of differences in the simulated mid-Pliocene climate relative to the pre-industrial in the three integrations are compared. In addition, patterns of predicted mid-Pliocene biomes resulting from the three climate simulations are compared in this study. Generally, difference of simulated surface climate between AGCM and AOGCM is larger than that between the two AOGCM runs, with and without flux adjustments. The simulated climate shows different pattern between AGCM and AOGCM particularly over low latitude oceans, subtropical land regions and high latitude oceans. The AOGCM simulations do not reproduce wetter environment in the subtropics relative to the present-day, which is suggested by terrestrial proxy data. The differences between the two types of AOGCM runs are small over the land, but evident over the ocean particularly in the North Atlantic and polar regions.

    As part of the laboratory component in Bush Physics for the 21st Century, a distance delivered physics course geared toward rural and Indigenous students in Alaska, students determine their village location on earth from simple sun angle measurements at local-noon during the spring equinox. Students measure the length of the sun shadow cast by a rod mounted on a horizontal surface, over short time intervals on or near the spring equinox during mid-day. Local-noon occurs when the sun is the highest and its corresponding shadow the shortest. Local noon, when expressed in Universal Time, can be directly converted to the local longitude in degrees. Local latitude in degrees, is obtained from the local-noon shadow length on the spring equinox and simple trigonometry. As an added bonus, using data from different sites, students can collaborate to approximate the circumference of the earth from their measurements. In the spirit of Eratosthenes, students envision an earth-sized pie wedge cut from a polar great-circle where the curve of the wedge on the earth's surface is the North-South distance between two often road-less sites (determined using Google Earth, a map or a globe), and the angle of the wedge is the difference between the site latitudes. The earth's circumference is calculated from this wedge. In 2012 with the aim of including Indigenous groups from other regions of the planet, we expanded this experiment to include teams from Japan, Puerto Rico, American Samoa, and New Zealand. We present our results from this pilot year.

    This study describes characteristics and evolution of the residual of the Earth energy budget (EB) individual components and the implied meridional transports during the twentieth century. This analysis considers two ensembles of AMIP-like experiments (Atmospheric Model Intercomparison Project) with prescribed evolution of sea surface temperature and sea ice concentration (SST-SIC), greenhouse gases (GHG), anthropogenic and volcanic aerosols over the entire twentieth century: ERA-20CM and ECHAM5-HAM model simulations. With the latter, additional sensitivity experiments are carried out by constraining either SST-SIC or aerosols to climatological values. The two models provide compatible estimates of the EBs and implied transport absolute values in recent decades. They are not in agreement in terms of global scale evolution: in the 1970s ERA-20CM shows a fast transition from negative to positive EBs at top of atmosphere (TOA) that is not found in ECHAM5-HAM. Climatological SST-SIC sensitivity experiments evidence that the aerosol forcing affects TOA and surface EBs by setting up an inter-hemispheric gradient after 1960. This is also reflected by an increased total transport in the Northern Hemisphere, while decreased in the Southern Hemisphere. ERA-20CM shows no evidence of a similar aerosol forcing. Sensitivity experiments with fixed pre-industrial aerosols show that transient SST are responsible for irregular spatio-temporal anomalies of surface and atmospheric EBs and transports. Surface and atmospheric anomalies oppose each other, and transient SSTs do not influence the EB changes at TOA. Impact of transient SST and GHG forcing on EBs and implied transports are robust across the two models.

    Globalization magnifies the problems that affect all people and that require large-scale human cooperation, for example, the overharvesting of natural resources and human-induced global warming. However, what does globalization imply for the cooperation needed to address such global social dilemmas? Two competing hypotheses are offered. One hypothesis is that globalization prompts reactionary movements that reinforce parochial distinctions among people. Large-scale cooperation then focuses on favoring one's own ethnic, racial, or language group. The alternative hypothesis suggests that globalization strengthens cosmopolitan attitudes by weakening the relevance of ethnicity, locality, or nationhood as sources of identification. In essence, globalization, the increasing interconnectedness of people worldwide, broadens the group boundaries within which individuals perceive they belong. We test these hypotheses by measuring globalization at both the country and individual levels and analyzing the relationship between globalization and individual cooperation with distal others in multilevel sequential cooperation experiments in which players can contribute to individual, local, and/or global accounts. Our samples were drawn from the general populations of the United States, Italy, Russia, Argentina, South Africa, and Iran. We find that as country and individual levels of globalization increase, so too does individual cooperation at the global level vis-à-vis the local level. In essence, "globalized" individuals draw broader group boundaries than others, eschewing parochial motivations in favor of cosmopolitan ones. Globalization may thus be fundamental in shaping contemporary large-scale cooperation and may be a positive force toward the provision of global public goods.

    Ladstaetter-Weissenmayer, A.; Meyer-Arnek, J.; Burrows, J. P.

    During the dry season, biomass burning is an important source of ozone precursors for the tropical troposphere, and ozone formation can occur in biomass burning plumes originating in Indonesia and northern Australia. Satellite based GOME (Global Ozone Measuring experiment) data are used to characterize the amount of tropospheric ozone production over this region during the El Niño event in September 1997 compared to a so called "normal" year 1998. Large scale biomass burning occurred over Kalimantan in 1997 caused by the absence of the northern monsoon rains, leading to significant increases in tropospheric ozone. Tropospheric ozone was determined from GOME data using the Tropospheric Excess Method (TEM). Backtrajectory calculations show that Indonesia is influenced every summer by the emissions of trace gases from biomass buring over northern Australia. But in 1997 over Indonesia an increasing of tropospheric ozone amounts can be observed caused by the fires over Indonesia itself as well as by northern Australia. The analysis of the measurements of BIBLE-A (Biomass Burning and Lightning Experiment) and using ATSR (Along the Track Scanning Radiometer) data show differences in the view to the intensity of fire counts and therefore in the amount of the emission of precursors of tropospheric ozone comparing September 1997 to September 1998.

    There is growing concern that short-term experiences in global health experiences (STEGH), undertaken by healthcare providers, trainees, and volunteers from high income countries in lower and middle income countries, risk harming the community by creating a parallel system of care separate from established community development efforts. At the same time, the inclusion of non-traditional actors in health planning has been the basis of the development of many Healthy Community Partnerships (HCP) being rolled out in Canada and the United States. These partnerships aim to bring all stakeholders with a role to play in health to the table to align efforts, goals and programs towards broad community health goals. This methodology paper reports on the process used in La Romana, Dominican Republic, in applying a modified HCP framework. This project succeeded at bringing visiting STEGH organizations into a coalition with key community partners and supported attempts to embed the work of STEGH within longer-term, established development plans. In presenting the work and process and lessons learned, the hope is that other communities that encounter significant investment from STEGH groups, and will gain the same benefits that were seen in La Romana with regards to improved information exchange, increased cross-communication between silos, and the integration of STEGH into the work of community partners.

    The School of Public Health at the State University of New York, Downstate Medical Center has sponsored a 6-8 week global health elective for fourth year medical students since 1980. The purpose of this elective is to provide students with an opportunity to observe the health care and public health delivery systems in low-income countries, provide medical service and have a cross-cultural experience. Over the course of the past 35 years, 388 students have participated in this global health elective in more than 41 low-income countries. The most popular sites include the Dominican Republic, Guatemala, India, Kenya and Thailand. Overall, interest in this elective has persisted throughout the course of time, sometimes temporarily increasing or decreasing with outside factors, such as the events of 11 September 2001 and the outbreak of Severe Acute Respiratory Syndrome in Asia. Recent annual applications for this elective have been as high as 44 out of a class of 200 students. Over the past 10 years, annual acceptance rates have varied, ranging from a low of 32 % in 2007-2008 to a high of 74 % in 2010-2011 and 2013-2014. Careful screening, including a written application, review of academic records and personal interviews has resulted in the selection of highly mature, adaptable and dedicated students who have performed well at overseas sites. Student rated satisfaction levels with this elective are almost universally high, with most rating it the best experience of their medical school years. Students undergo extensive preparation prior to their travel overseas, including a review of individual health and safety issues, travel and lodging, and the nature of the host country culture, health care system and assignment site. Downstate medical students are especially experienced in cross-cultural understanding because of the unusual diversity of the patient population in Brooklyn, and the diversity of local hospital staff and the medical school class.

    Design of experiments (DOE) is a systematic and cost-effective approach to system optimization by which the effects of multiple parameters and parameter interactions on a given response can be measured in few experiments. Herein, we describe the use of statistical DOE to improve a few of the analytical figures of merit of the infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI) source for mass spectrometry. In a typical experiment, bovine cytochrome c was ionized via electrospray, and equine cytochrome c was desorbed and ionized by IR-MALDESI such that the ratio of equine:bovine was used as a measure of the ionization efficiency of IR-MALDESI. This response was used to rank the importance of seven source parameters including flow rate, laser fluence, laser repetition rate, ESI emitter to mass spectrometer inlet distance, sample stage height, sample plate voltage, and the sample to mass spectrometer inlet distance. A screening fractional factorial DOE was conducted to designate which of the seven parameters induced the greatest amount of change in the response. These important parameters (flow rate, stage height, sample to mass spectrometer inlet distance, and laser fluence) were then studied at higher resolution using a full factorial DOE to obtain the globally optimized combination of parameter settings. The optimum combination of settings was then compared with our previously determined settings to quantify the degree of improvement in detection limit. The limit of detection for the optimized conditions was approximately 10 attomoles compared with 100 femtomoles for the previous settings, which corresponds to a four orders of magnitude improvement in the detection limit of equine cytochrome c.

    The emphasis on cultural competency for physicians and surgeons is increasingly important, as communication with both patients and other providers significantly affects individual and system-wide outcomes. International surgical training has been shown to improve leadership skills, cultural competency, and technical proficiency of participants in short-term follow-up. This study explores the long-term impact of international surgical mission experiences on developing participants' core competencies, professional outcomes, and commitment to global health. All 208 plastic and reconstructive surgeons who completed the Operation Smile Regan/Stryker fellowship programs between 2006 and 2015 were surveyed electronically. One hundred sixty-five surveys were returned, for an overall response rate of 79.3 percent. The majority of participants reported that the fellowship positively impacted all six Accreditation Council for Graduate Medical Education core competencies. Most participants who were attending physicians at the time of the survey were practicing general plastic surgery, with 42 percent in an academic/teaching environment, 32 percent in assistant/associate professor positions, and 6 percent in either a program director or department chairman position. The majority currently volunteer on local or international missions, and all respondents would consider volunteering again. Carefully structured and rigorously proctored programs such as the Regan/Stryker Fellowship offer plastic surgery residents the opportunity to gain valuable professional and personal experiences that benefit them long after their service experience. Programs of this nature can not only effectively improve cultural competency of physicians, but also positively influence their attitudes toward leadership and direct that potential to meet the growing need for surgical care in low- and middle-income countries.

  6. Comparison of Global Model Results from the Carbon-Land Model Intercomparison Project (C-LAMP) with Free-Air Carbon Dioxide Enrichment (FACE) Manipulation Experiments

    Free-Air CO2 Enrichment (FACE) manipulation experiments have been carried out at a handful of sites to gauge the response of the biosphere to significant increases in atmospheric [CO2]. Early synthesis results from four temperate forest sites suggest that the response of net primary productivity (NPP) is conserved across a broad range of productivity with a stimulation at the median of 23±2% when the surrounding air [CO2] was raised to 550~ppm. As a part of the Carbon-Land Model Intercomparison Project (C-LAMP), a community-based model-data comparison activity, the authors have performed a global FACE modeling experiment using two terrestrial biogeochemistry modules, CLM3-CASA' and CLM3-CN, coupled to the National Center for Atmospheric Research (NCAR) Community Climate System Model (CCSM). The two models were forced with an improved NCEP/NCAR reanalysis data set and reconstructed atmospheric [CO2] and N deposition data through 1997. At the beginning of 1997 in the transient simulations, global atmospheric [CO2] was abruptly raised to 550~ppm, the target value used at the FACE sites. In the control runs, [CO2] continued to rise following observations until 2004, after which it was held constant out to year 2100. In both simulations, the last 25 years of reanalysis forcing and a constant N deposition were applied after year 2004. Across all forest biomes, the NPP responses from both models are weaker than those reported for the four FACE sites. Moreover, model responses vary widely geographically with a decreasing trend of NPP increases from 40°N to 70°N. For CLM3- CASA', the largest responses occur in arid regions of western North America and central Asia, suggesting that responses are most strongly influenced by increased water use efficiency for this model. CLM3-CN exhibits consistently weaker responses than CLM3-CASA' with the strongest responses in central Asia, but significantly constrained by N limitation. C-LAMP is a sub-project of the Computational

    2016-04-01

    Global Collaborative STEM Education, as the name suggests, simultaneously supports two sets of knowledge and skills. The first set is STEM -- science, technology, engineering and math. The other set of content knowledge and skills is that of global collaboration. Successful global partnerships require awareness of one's own culture, the biases embedded within that culture, as well as developing awareness of the collaborators' culture. Workforce skills fostered include open-mindedness, perseverance when faced with obstacles, and resourceful use of technological "bridges" to facilitate and sustain communication. In respect for the 2016 GIFT Workshop focus, Global Collaborative STEM Education projects dedicated to astronomy research will be presented. The projects represent different benchmarks within the Global Collaborative STEM Education continuum, culminating in an astronomy research experience that fully reflects how the global STEM workforce collaborates. To facilitate wider engagement in Global Collaborative STEM Education, project summaries, classroom resources and contact information for established international collaborative astronomy research projects will be disseminated.

  12. Simulation of the variability and extremes of daily rainfall during the Indian summer monsoon for present and future times in a global time-slice experiment

    Energy Technology Data Exchange (ETDEWEB)

    May, W. [Danish Meteorological Institute, Lyngbyvej 100, 2100 Copenhagen (Denmark)

    2004-03-01

    In this study the simulation of the variability and extremes of daily rainfall during the Indian summer monsoon for the present-day and the future climate is investigated. This is done on the basis of a global time-slice experiment (TSL) with the ECHAM4 atmospheric general circulation model (GCM) at a high horizontal resolution of T106. The first time-slice (period: 1970-1999) represents the present-day climate and the second (2060-2089) the future climate. Moreover, observational rainfall data from the Global Precipitation Climatology Project (GPCP, 1997-2002) and rainfall data from the ECMWF re-analysis (ERA, 1958-2001) are considered. ERA reveals serious deficiencies in its representation of the variability and extremes of daily rainfall during the Indian summer monsoon. These are mainly a severe overestimation of the frequency of wet days over the oceans and in the Himalayas, where also the rainfall intensity is overestimated. Further, ERA shows unrealistically heavy rainfall events over the tropical Indian Ocean. The ECHAM4 atmospheric GCM at a horizontal resolution of T106, on the other hand, simulates the variability and extremes of daily rainfall in good agreement with the observations. The only marked deficiencies are an underestimation of the rainfall intensity on the west coast of the Indian peninsula and in Bangladesh, an overestimation over the tropical Indian Ocean, due to an erroneous northwestward extension of the tropical convergence zone, and an overestimation of the frequency of wet days in Tibet. Further, heavy rainfall events are relatively strong in the centre of the Indian peninsula. For the future, TSL predicts large increases in the rainfall intensity over the tropical Indian Ocean as well as in northern Pakistan and northwest India, but decreases in southern Pakistan, in the centre of the Indian peninsula, and over the western part of the Bay of Bengal. The frequency of wet days is markedly increased over the tropical Indian Ocean and

  15. Global teaching of global seismology

    Stein, S.; Wysession, M.

    2005-12-01

    Our recent textbook, Introduction to Seismology, Earthquakes, & Earth Structure (Blackwell, 2003) is used in many countries. Part of the reason for this may be our deliberate attempt to write the book for an international audience. This effort appears in several ways. We stress seismology's long tradition of global data interchange. Our brief discussions of the science's history illustrate the contributions of scientists around the world. Perhaps most importantly, our discussions of earthquakes, tectonics, and seismic hazards take a global view. Many examples are from North America, whereas others are from other areas. Our view is that non-North American students should be exposed to North American examples that are type examples, and that North American students should be similarly exposed to examples elsewhere. For example, we illustrate how the Euler vector geometry changes a plate boundary from spreading, to strike-slip, to convergence using both the Pacific-North America boundary from the Gulf of California to Alaska and the Eurasia-Africa boundary from the Azores to the Mediterranean. We illustrate diffuse plate boundary zones using western North America, the Andes, the Himalayas, the Mediterranean, and the East Africa Rift. The subduction zone discussions examine Japan, Tonga, and Chile. We discuss significant earthquakes both in the U.S. and elsewhere, and explore hazard mitigation issues in different contexts. Both comments from foreign colleagues and our experience lecturing overseas indicate that this approach works well. Beyond the specifics of our text, we believe that such a global approach is facilitated by the international traditions of the earth sciences and the world youth culture that gives students worldwide common culture. For example, a video of the scene in New Madrid, Missouri that arose from a nonsensical earthquake prediction in 1990 elicits similar responses from American and European students.

    Full Text Available Global marketing management needs to be implemented based on valid, i.e. reliable, timely, verifiable and high-quality marketing information, which will enable valid decision-making in global business operations. The efficiency and effectiveness of decision-making is directly related to considering the comprehensive state of the chosen segment(s of the global market. Informational completion of the picture of a market requires devising and implementing a large number of activities set in a logical sequence. Practical experience has shown that decision-making in managing global business activities of affirmed companies is based on accumulated knowledge and is regarded as a specific form of creativity, unlike operationalization and supervision, which are mostly organizational and technical issues. Bearing this in mind, the informational basis in the operation of global companies should be viewed in accordance with its significance and function in global marketing management.

    2010-01-01

    This article reviews the contributions of the UN Convention on the Rights of Persons with Disabilities (CRPD) to the progressive development of both international human rights law and global health law and governance. It provides a summary of the global situation of persons with disabilities and outlines the progressive development of international disability standards, noting the salience of the shift from a medical model of disability to a rights-based social model reflected in the CRPD. Thereafter, the article considers the Convention's structure and substantive content, and then analyzes in specific detail the particular contributions of the Convention to health and human rights law and global health governance. It concludes with an exploration of the potential implications of the CRPD's innovations for some of the most pressing issues in global health governance, including the Convention's contributions to the principle of participation in decision-making.

    Full Text Available Utopia is defined in Encarta Dictionary as “an ideal and perfect place or state, where everyone lives in harmony and everything is for the best.” Developments all around the world especially in the last decade have supported the idea that global peace is nothing but just a utopian dream. However, for centuries a group of believers have always been in search of global peace via different means. This book, titled as “Global Peace through the Global University System”, can be considered as one of the artifacts of this search.Actually this book is a collection of papers presented in working conference on the Global University System (GUS hosted by the University of Tampere, Finland in 1999. The main goal of the conference was bringing international experts to share their philosophy, past and present experiences about the GUS. The conference was held by the University of Tampere because UNESCO has an agreement with the University to establish the UNESCOChair in Global e-Learning.

    2015-01-01

    Traditional study abroad experiences take a variety of forms with most incorporating extensive cultural emersion and a focus on global learning skills. Here we ask the question: Can this type of experience co-exist with a quality scientific experience and continued progression through a typically rigorous undergraduate neuroscience curriculum? What are the potential costs and benefits of this approach? How do we increase student awareness of study abroad opportunities and inspire them to participate? We outline programs that have done this with some success and point out ways to cultivate this approach for future programs. These programs represent a variety of approaches in both their duration and role in a given curriculum. We discuss a one-week first year seminar program in Berlin, a summer study abroad course in Munich and Berlin, semester experiences and other options offered through the Danish Institute for Study Abroad in Copenhagen. Each of these experiences offers opportunities for interfacing global learning with neuroscience.

'Open Access' publishing is expected to become an increasingly important format for peer reviewed academic journals and that Globalization and Health is 'Open Access' is appropriate. The rationale behind starting a journal dedicated to globalization and health is three fold:Firstly: Globalization is reshaping the social geography within which we might strive to create health or prevent disease. The determinants of health - be they a SARS virus or a predilection for fatty foods - have joined us in our global mobility. Driven by economic liberalization and changing technologies, the phenomenon of 'access' is likely to dominate to an increasing extent the unfolding experience of human disease and wellbeing.Secondly: Understanding globalization as a subject matter itself needs certain benchmarks and barometers of its successes and failings. Health is one such barometer. It is a marker of social infrastructure and social welfare and as such can be used to either sound an alarm or give a victory cheer as our interconnectedness hurts and heals the populations we serve.And lastly: In as much as globalization can have an effect on health, it is also true that health and disease has an effect on globalization as exemplified by the existence of quarantine laws and the devastating economic effects of the AIDS pandemic.A balanced view would propose that the effects of globalization on health (and health systems) are neither universally good nor bad, but rather context specific. If the dialogue pertaining to globalization is to be directed or biased in any direction, then it must be this: that we consider the poor first.

    The Global SFA Registry sought to assess safety, clinical benefit, and outcomes of the Lutonix 035 drug-coated balloon (DCB) in a heterogeneous, real-world patient population at 12 and 24 months. Numerous clinical studies have evaluated the use of angioplasty for revascularization of femoropopliteal arteries in peripheral arterial disease with restenosis rates of 40% to 60% at 6 to 12 months. Data from recent studies document decreased restenosis rates and improvement in patency in patients receiving angioplasty of femoropopliteal arteries with DCBs. The multicenter, prospective study enrolled 691 patients in 38 centers from 10 countries treated with the Lutonix 035 DCB in femoropopliteal lesions. The primary safety endpoint was freedom from a composite of target vessel restenosis, major index limb amputation, and device- or procedure-related death at 30 days. The primary effectiveness endpoint was freedom from target lesion restenosis at 12 months. Secondary endpoints were acute device and procedural success and clinically assessed primary patency. Freedom at 30 days from the composite safety endpoint was 99.4%. Freedom from target lesion restenosis was 93.4%/89.3% for the overall population, 93.2%/88.2% for long lesions up to 500 mm, and 90.7%/84.6% for in-stent restenosis at 12/24 months. Clinically assessed primary patency by Kaplan-Meier estimates was 85.4%/75.6% at 12/24 months. More than 76% of patients showed improvement of at least 1 Rutherford category.

    How can universities create engaged citizens and global leaders? Each year, a select group of advanced practice nursing students at Baylor University Louise Herrington School of Nursing travel to Africa for a month-long clinical mission experience. Students work alongside local and missionary healthcare providers in a comprehensive Christian outreach to the community at a high-volume clinic. Creating rich learning experiences in a global setting in significant and sustainable ways is difficult, but intentionally focusing on what we are called to do and who we serve provides ballast for faculty and students. The success of the trip in preparing students to be global influencers is evident by the work graduates elect to do around the world, following graduation.

    In this study, responses of the Kuroshio Extension (KE) path state to near-term (2006-2035) global warming are investigated using a Kuroshio-resolving atmosphere-ocean coupled model. Under the representative concentration pathway 4.5 (RCP4.5) forcing, the KE system is intensified and its path state tends to move northward and becomes more stable. It is suggested that the local anticyclonic wind stress anomalies in the KE region favor the spin-up of the southern recirculation gyre, and the remote effect induced by the anticyclonic wind stress anomalies over the central and eastern midlatitude North Pacific also contributes to the stabilization of the KE system substantially. The dominant role of wind stress forcing on KE variability under near-term global warming is further confirmed by adopting a linear 1.5 layer reduced-gravity model forced by wind stress curl field from the present climate model. It is also found that the main contributing longitudinal band for KE index (KEI) moves westward in response to the warmed climate. This results from the northwestward expansion of the large-scale sea level pressure (SLP) field.

To do this exploration, two research methods, content analysis and the questionnaire, were adopted. The content of an example of global coursebooks, Headway Intermediate (H/I, in addition to the perception of 251 of its users at Institute Bourguiba for Living Languages (IBLV were investigated. The results obtained revealed that “globality,” in terms of connectedness, inappropriacy, and inclusivity is partial in H/I as learners’ perceptions of it do not map with the content in the coursebook. This study raises questions about the suitability of global coursebooks to globally diverse learners and reveals the necessity of taking measures in the direction of localizing the content of English as a foreign language (EFL coursebooks.

    2015-05-01

    The modulated pulsed power magnetron sputtering (MPPMS) discharge processes are numerically modeled and experimentally investigated, in order to explore the effect of the pressure on MPPMS discharges as well as on the microstructure of the deposited thin films. A global plasma model has been developed based on a volume-averaged global description of the ionization region, considering the loss of electrons by cross-B diffusion. The temporal variations of internal plasma parameters at different pressures from 0.1 to 0.7 Pa are obtained by fitting the model to duplicate the experimental discharge data, and Cu thin films are deposited by MPPMS at the corresponding pressures. The surface morphology, grain size and orientation, and microstructure of the deposited thin films are investigated by scanning electron microscopy, transmission electron microscopy, and x-ray diffraction. By increasing the pressure from 0.1 to 0.7 Pa, both the ion bombardment energy and substrate temperature which are estimated by the modeled plasma parameters decrease, corresponding to the observed transition of the deposited thin films from a void free structure with a wide distribution of grain size (zone T) into an underdense structure with a fine fiber texture (zone 1) in the extended structure zone diagram (SZD). The microstructure and texture transition of Cu thin films are well-explained by the extended SZD, suggesting that the primary plasma processes are properly incorporated in the model. The results contribute to the understanding of the characteristics of MPPMS discharges, as well as its correlation with the microstructure and texture of deposited Cu thin films.

    The mid-Pliocene Warm Period (3.29 to 2.97 Ma BP) has been identified as an analogue for the future, with the potential to help understand climate processes in a warmer than modern world. Sets of climate proxies, combined to provide boundary conditions for Global Climate Model (GCM) simulations of the mid-Pliocene, form the basis for the international, data-driven Pliocene Model Intercomparison Project (PlioMIP). Here, we outline the strategy for implementing pre-industrial (modern) and mid-Pliocene forcings and boundary conditions into the GENESIS version 3 GCM, as part of PlioMIP. We describe the prescription of greenhouse gas concentrations and orbital parameters and the implementation of geographic boundary conditions such as land-ice-sea distribution, topography, sea surface temperatures, sea ice extent, vegetation, soils, and ice sheets. We further describe model-specific details including spin-up and integration times. In addition, the global climatology of the mid-Pliocene as simulated by the GENESIS v3 GCM is analyzed and compared to the pre-industrial control simulation. The simulated climate of the mid-Pliocene warm interval is found to differ considerably from pre-industrial. We identify model sensitivity to imposed forcings, and internal feedbacks that collectively affect both local and far-field responses. Our analysis points out the need to assess both the direct impacts of external forcings and the combined effects of indirect, internal feedbacks. This paper provides the basis for assessing model biases within the PlioMIP framework, and will be useful for comparisons with other studies of mid-Pliocene climates.

    2013-09-01

    For better understanding the life cycle of the convective systems and their interactions with the environment, a joint Indo-French satellite mission named Megha-Tropiques has been launched in October 2011 in a low-inclination (20°) orbit. In the present study, we show the first results on the comparison of relative humidity (RH) obtained using a six-channel microwave sounder, covering from surface to 100 hPa, from one of the payloads SAPHIR (Sounder for Atmospheric Profiling of Humidity in the Inter-tropical Regions). The RH observations from SAPHIR illustrated the numerous scales of variability in the atmosphere both vertically and horizontally. As a part of its validation, we compare SAPHIR RH with simultaneous observations from a network of radiosondes distributed across the world (±30° latitude), other satellites (Atmospheric Infrared Sounder, Infrared Atmospheric Sounder Interferometer, Constellation Observation System for Meteorology Ionosphere and Climate (COSMIC)), and various reanalysis (National Center for Environmental Prediction (NCEP), European Center for Medium-Range Weather Forecasts reanalysis (ERA)-Interim, Modern-Era Retrospective Analysis for Research and Application (MERRA)) products. Being at a low inclination, SAPHIR is able to show better global coverage when compared to any other existing satellites in the tropical region where some important weather processes take place. A very good correlation is noticed with the RH obtained from a global radiosonde network particularly in the altitude range corresponding to 850-250 hPa, thus providing a valuable data set for investigating the convective processes. In the case of satellite data sets, SAPHIR RH is well comparable with COSMIC RH. Among the reanalysis products, NCEP shows less difference with SAPHIR followed by ERA-Interim, and the MERRA products show large differences in the middle and upper troposphere.

    Global warming-like deforestation, the ozone hole and the loss of species- has become one of the late 20the century icons of global environmental damage. The threat, is not the reality, of such a global climate change has motivated governments. businesses and environmental organisations, to take serious action ot try and achieve serious control of the future climate. This culminated last December in Kyoto in the agreement for legally-binding climate protocol. In this series of three lectures I will provide a perspective on the phenomenon of global warming that accepts the scientific basis for our concern, but one that also recognises the dynamic interaction between climate and society that has always exited The future will be no different. The challenge of global warning is not to pretend it is not happening (as with some pressure groups), nor to pretend it threatens global civilisation (as with other pressure groups), and it is not even a challenge to try and stop it from happening-we are too far down the ro...

    Across the Americas, biofuels production systems are diverse due to geographic conditions, historical patterns of land tenure, different land use patterns, government policy frameworks, and relations between the national state and civil society, all of which shape the role that biofuels play in individual nations. Although many national governments throughout the Americas continue to incentivize growth of the biofuels industry, one key challenge for biofuels sustainability has been concern about its social impacts. In this article, we discuss some of the key social issues and tensions related to the recent expansion of biofuels production in Mexico, Colombia, and Brazil. We argue that a process of "simplification" of ecological and cultural diversity has aided the expansion of the biofuels frontier in these countries, but is also undermining their viability. We consider the ability of governments and non-state actors in multi-stakeholder initiatives (MSI) to address social and environmental concerns that affect rural livelihoods as a result of biofuels expansion. We analyze the tensions between global sustainability standards, national level policies for biofuels development, and local level impacts and visions of sustainability. We find that both government and MSI efforts to address sustainability concerns have limited impact, and recommend greater incorporation of local needs and expertise to improve governance.

    IYA2009 is a global collaboration between almost 140 nations and more than 50 international organisations sharing the same vision. Besides the common brand, mission, vision and goals, IAU established eleven cornerstones programmes to support the different IYA2009 stakeholder to organize events, activities under a common umbrella. These are global activities centred on specific themes and are aligned with IYA2009's main goals. Whether it is the support and promotion of women in astronomy, the preservation of dark-sky sites around the world or educating and explaining the workings of the Universe to millions, the eleven Cornerstones are key elements in the success of IYA2009. However, the process of implementing global projects across cultural boundaries is challenging and needs central coordination to preserve the pre-established goals. During this talk we will examine the ups and downs of coordinating such a project and present an overview of the principal achievements for the Cornerstones so far.

    This paper measures trends in global interpersonal inequality during 1975–2010 using data from the most recent version of the World Income Inequality Database (WIID). The picture that emerges using ‘absolute,’ and even ‘centrist’ measures of inequality, is very different from the results obtained...... using standard ‘relative’ inequality measures such as the Gini coefficient or Coefficient of Variation. Relative global inequality has declined substantially over the decades. In contrast, ‘absolute’ inequality, as captured by the Standard Deviation and Absolute Gini, has increased considerably...... and unabated. Like these ‘absolute’ measures, our ‘centrist’ inequality indicators, the Krtscha measure and an intermediate Gini, also register a pronounced increase in global inequality, albeit, in the case of the latter, with a decline during 2005 to 2010. A critical question posed by our findings is whether...

    The increased international trade led to growing concerns over sustainability of biofuels and a variety of governance systems has emerged to regulate the bioenergy sector for maximization of the benefits and minimization of the possible negative impacts. The general concept of governance is used in different ways. But in this chapter it is used in the broad sense of governance processes undertaken by governments, market actors, voluntary organizations or networks. This concept of governance recognizes the interdependence of the public, market-based and voluntary governing processes, and the relationships that may exist between them. A survey was designed with the objective of analyzing stakeholders' views, experiences, and ideas in relation to the governance challenges. The survey revealed a broad support for existing and new co-regulation among stakeholders, but also that low share of certified land is seen as a challenge for both forestry and agriculture.

    This paper describes the second phase of an Observing System Simulation Experiment (OSSE) that utilizes the synthetic measurements from a constellation of satellites measuring atmospheric composition from geostationary (GEO) Earth orbit presented in part I of the study. Our OSSE is focused on carbon monoxide observations over North America, East Asia and Europe where most of the anthropogenic sources are located. Here we assess the impact of a potential GEO constellation on constraining northern hemisphere (NH) carbon monoxide (CO) using data assimilation. We show how cloud cover affects the GEO constellation data density with the largest cloud cover (i.e., lowest data density) occurring during Asian summer. We compare the modeled state of the atmosphere (Control Run), before CO data assimilation, with the known "true" state of the atmosphere (Nature Run) and show that our setup provides realistic atmospheric CO fields and emission budgets. Overall, the Control Run underestimates CO concentrations in the northern hemisphere, especially in areas close to CO sources. Assimilation experiments show that constraining CO close to the main anthropogenic sources significantly reduces errors in NH CO compared to the Control Run. We assess the changes in error reduction when only single satellite instruments are available as compared to the full constellation. We find large differences in how measurements for each continental scale observation system affect the hemispherical improvement in long-range transport patterns, especially due to seasonal cloud cover. A GEO constellation will provide the most efficient constraint on NH CO during winter when CO lifetime is longer and increments from data assimilation associated with source regions are advected further around the globe.

  19. Improving Global Development Using Agile

    Avritzer, Alberto; Bronsard, Francois; Matos, Gilberto

    Global development promises important productivity and capability advantages over centralized work by optimally allocating tasks according to locality, expertise or cost. All too often, global development also introduces a different set of communication and coordination challenges that can negate all the expected benefits and even cause project failures. Most common problems have to do with building trust or quick feedback loops between distributed teams, or with the integration of globally developed components. Agile processes tend to emphasize the intensity of communication, and would seem to be negatively impacted by team distribution. In our experience, these challenges can be overcome, and agile processes can address some of the pitfalls of global development more effectively than plan-driven development. This chapter discusses how to address the difficulties faced when adapting agile processes to global development and the improvements to global development that adopting agile can produce.

    Keller, Michael; Bustamante, Mercedes; Gash, John; Silva Dias, Pedro

    Amazonia and Global Change synthesizes results of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) for scientists and students of Earth system science and global environmental change. LBA, led by Brazil, asks how Amazonia currently functions in the global climate and biogeochemical systems and how the functioning of Amazonia will respond to the combined pressures of climate and land use change, such as • Wet season and dry season aerosol concentrations and their effects on diffuse radiation and photosynthesis • Increasing greenhouse gas concentration, deforestation, widespread biomass burning and changes in the Amazonian water cycle • Drought effects and simulated drought through rainfall exclusion experiments • The net flux of carbon between Amazonia and the atmosphere • Floodplains as an important regulator of the basin carbon balance including serving as a major source of methane to the troposphere • The impact of the likely increased profitability of cattle ranching. The book will serve a broad community of scientists and policy makers interested in global change and environmental issues with high-quality scientific syntheses accessible to nonspecialists in a wide community of social scientists, ecologists, atmospheric chemists, climatologists, and hydrologists.

    2008-07-15

    A preindustrial climate experiment was conducted with the third version of the CNRM global atmosphere-ocean-sea ice coupled model (CNRM-CM3) for the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4). This experiment is used to investigate the main physical processes involved in the variability of the North Atlantic ocean convection and the induced variability of the Atlantic meridional overturning circulation (MOC). Three ocean convection sites are simulated, in the Labrador, Irminger and Greenland-Iceland-Norwegian (GIN) Seas in agreement with observations. A mechanism linking the variability of the Arctic sea ice cover and convection in the GIN Seas is highlighted. Contrary to previous suggested mechanisms, in CNRM-CM3 the latter is not modulated by the variability of freshwater export through Fram Strait. Instead, the variability of convection is mainly driven by the variability of the sea ice edge position in the Greenland Sea. In this area, the surface freshwater balance is dominated by the freshwater input due to the melting of sea ice. The ice edge position is modulated either by northwestward geostrophic current anomalies or by an intensification of northerly winds. In the model, stronger than average northerly winds force simultaneous intense convective events in the Irminger and GIN Seas. Convection interacts with the thermohaline circulation on timescales of 5-10 years, which translates into MOC anomalies propagating southward from the convection sites. (orig.)

While acknowledging the importance of the work of both Rose and Potter, this collection’s editor, Tony Mitchell, contests their respective views that rap and hip-hop are essentially expressions of African-American culture, and that all forms of rap and hip-hop derive from these origins. He argues that these forms have become ‘a vehicle for global youth affiliations and a tool for reworking local iden- tity all over the world’.

    Global Arrays (GA) is a distributed-memory programming model that allows for shared-memory-style programming combined with one-sided communication, to create a set of tools that combine high performance with ease-of-use. GA exposes a relatively straightforward programming abstraction, while supporting fully-distributed data structures, locality of reference, and high-performance communication. GA was originally formulated in the early 1990’s to provide a communication layer for the Northwest Chemistry (NWChem) suite of chemistry modeling codes that was being developed concurrently.

    The recent data from SNO are analysed with the global data from the other solar neutrino experiments, first in a model independent way and then assuming two-flavour oscillations. Neutrino oscillations to active flavours can best explain the global data with the LMA solution emerging as the best-fit. However, transitions to 'mixed' states with up to 30% sterile mixture are still allowed at 1{sigma}.

    Varwick, J. (ed.)

    2008-07-01

    For some years, the interest in global environmental problems and global environmental policy increased substantially. In order to prevent a sustainable and irreversible damage of the global ecological systems, it requires an ecological restructuring of the economy of the industrial nations and a environmental compatible development in the developing countries. Under this aspect, the book under consideration dedicates itself to this problem by means of five scientific contributions: (a) The principle sustainability (Felix Ekardt); (b) Climate change as a world problem (Andreas Rechkemmer); (c) The role of the pioneer of the European Union in the international climate policy: Successes and challenges (Sebastian Oberthuer); (d) Cause for conflict water (Tobias Lindenberg); (e) Environmental political instruments in theory and practice (Johanna Reichenbach/Till Requate). Instruction practice also is concerned with a cross section topic consisting of environmental and European politics: Competent instructions concerning to the European Union - an instruction series for the secondary school I (George Wiesseno, Valentin Eck). Two forum contributions go beyond the topic: (a) Against rigid (society-)political borders in the science (Tim Engartner); (b) Elections in Hamburg - Schwarz-Gruen as new coalition model for the federation? In the column 'the current topic' Gotthard Breit reports on the protests against China on the occasion of the Olympic Games 2008. The author focuses some strangenesses in the debate and pleads for a sober view of the topic. With a report on 'the Beutelsbacher discussions' at 18th to 20th February, 2008, Timo Web finishes this book.

  10. Global gamesmanship.

    Science.gov (United States)

    MacMillan, Ian C; van Putten, Alexander B; McGrath, Rita Gunther

    2003-05-01

    Competition among multinationals these days is likely to be a three-dimensional game of global chess: The moves an organization makes in one market are designed to achieve goals in another in ways that aren't immediately apparent to its rivals. The authors--all management professors-call this approach "competing under strategic interdependence," or CSI. And where this interdependence exists, the complexity of the situation can quickly overwhelm ordinary analysis. Indeed, most business strategists are terrible at anticipating the consequences of interdependent choices, and they're even worse at using interdependency to their advantage. In this article, the authors offer a process for mapping the competitive landscape and anticipating how your company's moves in one market can influence its competitive interactions in others. They outline the six types of CSI campaigns--onslaughts, contests, guerrilla campaigns, feints, gambits, and harvesting--available to any multiproduct or multimarket corporation that wants to compete skillfully. They cite real-world examples such as the U.S. pricing battle Philip Morris waged with R.J. Reynolds--not to gain market share in the domestic cigarette market but to divert R.J. Reynolds's resources and attention from the opportunities Philip Morris was pursuing in Eastern Europe. And, using data they collected from their studies of consumer-products companies Procter & Gamble and Unilever, the authors describe how to create CSI tables and bubble charts that present a graphical look at the competitive landscape and that may uncover previously hidden opportunities. The CSI mapping process isn't just for global corporations, the authors explain. Smaller organizations that compete with a portfolio of products in just one national or regional market may find it just as useful for planning their next business moves.

  11. Global warming

    Science.gov (United States)

    Houghton, John

    2005-06-01

    'Global warming' is a phrase that refers to the effect on the climate of human activities, in particular the burning of fossil fuels (coal, oil and gas) and large-scale deforestation, which cause emissions to the atmosphere of large amounts of 'greenhouse gases', of which the most important is carbon dioxide. Such gases absorb infrared radiation emitted by the Earth's surface and act as blankets over the surface keeping it warmer than it would otherwise be. Associated with this warming are changes of climate. The basic science of the 'greenhouse effect' that leads to the warming is well understood. More detailed understanding relies on numerical models of the climate that integrate the basic dynamical and physical equations describing the complete climate system. Many of the likely characteristics of the resulting changes in climate (such as more frequent heat waves, increases in rainfall, increase in frequency and intensity of many extreme climate events) can be identified. Substantial uncertainties remain in knowledge of some of the feedbacks within the climate system (that affect the overall magnitude of change) and in much of the detail of likely regional change. Because of its negative impacts on human communities (including for instance substantial sea-level rise) and on ecosystems, global warming is the most important environmental problem the world faces. Adaptation to the inevitable impacts and mitigation to reduce their magnitude are both necessary. International action is being taken by the world's scientific and political communities. Because of the need for urgent action, the greatest challenge is to move rapidly to much increased energy efficiency and to non-fossil-fuel energy sources.

    Globalization theories have proliferated over the past two decades. However, global developments have yet to be systematically incorporated into theories around violence against women. This article proposes to add a global level to the existing ecological model framework, popularized by Lori Heise in 1998, to explore the relationships between global processes and experiences of violence against women. Data from the Maldives and Cambodia are used to assess how globalized ideologies, economic development and integration, religious fundamentalisms, and global cultural exchange, as components of a larger globalization process, have affected men and women's experiences and perceptions of violence against women.

    2016-11-03

    Preserving global public goods, such as the planet's ecosystem, depends on large-scale cooperation, which is difficult to achieve because the standard reciprocity mechanisms weaken in large groups. Here we demonstrate a method by which reciprocity can maintain cooperation in a large-scale public goods game (PGG). In a first experiment, participants in groups of on average 39 people play one round of a Prisoner's Dilemma (PD) with their two nearest neighbours on a cyclic network after each PGG round. We observe that people engage in "local-to-global" reciprocity, leveraging local interactions to enforce global cooperation: Participants reduce PD cooperation with neighbours who contribute little in the PGG. In response, low PGG contributors increase their contributions if both neighbours defect in the PD. In a control condition, participants do not know their neighbours' PGG contribution and thus cannot link play in the PD to the PGG. In the control we observe a sharp decline of cooperation in the PGG, while in the treatment condition global cooperation is maintained. In a second experiment, we demonstrate the scalability of this effect: in a 1,000-person PGG, participants in the treatment condition successfully sustain public contributions. Our findings suggest that this simple "local-to-global" intervention facilitates large-scale cooperation.

    Background and Objectives: To identify the effects of global health electives over a decade in a pediatric residency program. Methods: This was an anonymous email survey of the Boston Combined Residency alumni funded for global health electives from 2002 to 2011. A test for trend in binomial proportions and logistic regression were used to document associations between elective and participant characteristics and the effects of the electives. Qualitative data were also analyzed. Results: Of the 104 alumni with available email addresses, 69 (66%) responded, describing 94 electives. Elective products included 27 curricula developed, 11 conference presentations, and 7 academic publications. Thirty-two (46%) alumni continued global health work. Previous experience, previous travel to the site, number of global electives, and cumulative global elective time were associated with postresidency work in global health or with the underserved. Conclusions: Resident global electives resulted in significant scholarship and teaching and contributed to long-term career trajectories. PMID:28229096

    Full Text Available Globalization is an ongoing phenomenon trying to redefine the economic, social, cultural and political dynamics of contemporary societies. The communication among countries and not only them, has been increased expanding political ties, making possible greater economic integration and wider cultural relations combined with augmented global wealth across the world. But, the process of globalization is in wider terms considered a beneficial one, but also viewed by some countries as a menace to national sovereignty and national culture. This paper tries to explain the obstacles to the process of globalization and its attendant benefits. Although globalization has arisen as a result of a more stable world, the factors that had contributed to its rise also help the factions interested to bring destabilization. In an academic approach in this article, between the research and comparative methods, I have been trying to get the maxims between economy, politics and diplomacy in their efforts of affecting the global era.

    2011-04-01

    Although the resources and knowledge for achieving improved global health exist, a new, critical paradigm on health as an aspect of human development, human security, and human rights is needed. Such a shift is required to sufficiently modify and credibly reduce the present dominance of perverse market forces on global health. New scientific discoveries can make wide-ranging contributions to improved health; however, improved global health depends on achieving greater social justice, economic redistribution, and enhanced democratization of production, caring social institutions for essential health care, education, and other public goods. As with the quest for an HIV vaccine, the challenge of improved global health requires an ambitious multidisciplinary research program.

    Global awareness is an important topic in higher education's curricula to prepare students for the 21st century, to adequately respond to today's globalized world and develop world citizenship. To investigate college students' perceptions on global awareness, a survey on global-mindedness including skills and experiences related to global citizenship was given to 445 college students majoring in education, business, and engineering in two large cities of China. Results show that students majoring in education scored significantly higher than those in the other disciplines on the summarized dimensions, e.g., societal responsibility, skilled disposition, and tolerance of differences. All respondents reported that they had limited experiences in volunteer work, collaborative activities, and community services. Higher education curriculum development to prepare responsible world citizens is discussed regarding the current education system of China.

    Urban heat island (UHI) is a widely investigated phenomenon in the field of urban climate characterized by the warming of urban areas relative to its surrounding rural environs. Being able to understand the mechanism behind the UHI formation of a city and distinguish its impact from that of global climate change is indispensable when identifying adaptation and mitigation strategies. However, the lack of UHI studies many cities especially for developing countries makes it difficult to generalize the mechanism for UHI formation. Thus, there is an impending demand for studies that focus on the simultaneous analyses of UHI and its trends throughout the world. Hence, we propose a subfield of urban climatology, called "global urban climatology" (GUC), which mainly focuses on the uniform understanding of urban climates across all cities, globally. By using globally applicable methodologies to quantify and compare urban heat islands of cities with diverse backgrounds, including their geography, climate, socio-demography, and other factors, a universal understanding of the mechanisms underlying the formation of the phenomenon can be established. The implementation of GUC involves the use of globally acquired historical observation networks, gridded meteorological parameters from climate models, global geographic information system datasets; the construction of a distributed urban parameter database; and the development of techniques necessary to model the urban climate. Research under GUC can be categorized into three approaches. The collaborative approach (1st) relies on the collection of data from micro-scale experiments conducted worldwide with the aid or development of professional social networking platforms; the analytical approach (2nd) relies on the use of global weather station datasets and their corresponding objectively analysed global outputs; and the numerical approach (3rd) relies on the global estimation of high-resolution urban-representative parameters as

  5. Increasing women in leadership in global health.

    Science.gov (United States)

    Downs, Jennifer A; Reif, Lindsey K; Hokororo, Adolfine; Fitzgerald, Daniel W

    2014-08-01

    Globally, women experience a disproportionate burden of disease and death due to inequities in access to basic health care, nutrition, and education. In the face of this disparity, it is striking that leadership in the field of global health is highly skewed towards men and that global health organizations neglect the issue of gender equality in their own leadership. Randomized trials demonstrate that women in leadership positions in governmental organizations implement different policies than men and that these policies are more supportive of women and children. Other studies show that proactive interventions to increase the proportion of women in leadership positions within businesses or government can be successful. Therefore, the authors assert that increasing female leadership in global health is both feasible and a fundamental step towards addressing the problem of women's health. In this Perspective, the authors contrast the high proportion of young female trainees who are interested in academic global health early in their careers with the low numbers of women successfully rising to global health leadership roles. The authors subsequently explore reasons for female attrition from the field of global health and offer practical strategies for closing the gender gap in global health leadership. The authors propose solutions aimed to promote female leaders from both resource-wealthy and resource-poor countries, including leadership training grants, mentorship from female leaders in global professions, strengthening health education in resource-poor countries, research-enabling grants, and altering institutional policies to support women choosing a global health career path.

    Full Text Available ABSTRACTThe gathering momentum of globalization in the world economy has coincided with the spread of political democracy across countries. Economies have become global. But politics remains national. This essay explores the relationship between globalization and democracy, which is neither linear nor characterized by structural rigidities. It seeks to analyze how globalization might constrain degrees of freedom for nation states and space for democratic politics, and how political democracy within countries might exercise some checks and balances on markets and globalization. The essential argument is that the relationship between globalization and democracy is dialectical and does not conform to ideological caricatures.

  12. COMPETING CONCEPTIONS OF GLOBALIZATION

    Directory of Open Access Journals (Sweden)

    Leslie Sklair

    2015-08-01

    Full Text Available Globalization is a relatively new idea in the social sciences, although people who work in and write about the mass media, transnational corporations and international business have been using it for some time. The purpose of this paper is to critically review the ways in which sociologists and other social scientists use ideas of globalization and to evaluate the fruitfulness of these competing conceptions. The central feature of the idea of globalization is that many contemporary problems cannot be adequately studied at the level of nation-states, that is, in terms of each country and its inter-national relations. Instead, they need to be conceptualized in terms of global processes. Some have even gone so far as to predict that global forces, by which they usually mean transnational corporations and other global economic institutions, global culture or globalizing belief systems/ideologies of various types, or a combination of all of these, are becoming so powerful that the continuing existence of the nation-state is in serious doubt. This is not a necessary consequence of most theories of globalization. The argument of this paper is that much of the globalization literature is confused because not all those who use the term distinguish it clearly enough from internation-alization, and some writers appear to use the two terms interchangeably. I argue that a clear distinction must be drawn between the inter-national and the global. The hyphen in inter-national is to distinguish (inadequate conceptions of the global' founded on the existing even if changing system of nation-states, from (genuine conceptions of the global based on the emergence of global processes and a global system of social relations not founded on national characteristics or nation-states. This global system theory is the framework for my own research. Globalization studies can be categorized on the basis of four research clusters:1. The world-systems approach; 2. The global

  13. Global solidarity, migration and global health inequity.

    Science.gov (United States)

    Eckenwiler, Lisa; Straehle, Christine; Chung, Ryoa

    2012-09-01

    The grounds for global solidarity have been theorized and conceptualized in recent years, and many have argued that we need a global concept of solidarity. But the question remains: what can motivate efforts of the international community and nation-states? Our focus is the grounding of solidarity with respect to global inequities in health. We explore what considerations could motivate acts of global solidarity in the specific context of health migration, and sketch briefly what form this kind of solidarity could take. First, we argue that the only plausible conceptualization of persons highlights their interdependence. We draw upon a conception of persons as 'ecological subjects' and from there illustrate what such a conception implies with the example of nurses migrating from low and middle-income countries to more affluent ones. Next, we address potential critics who might counter any such understanding of current international politics with a reference to real-politik and the insights of realist international political theory. We argue that national governments--while not always or even often motivated by moral reasons alone--may nevertheless be motivated to acts of global solidarity by prudential arguments. Solidarity then need not be, as many argue, a function of charitable inclination, or emergent from an acknowledgment of injustice suffered, but may in fact serve national and transnational interests. We conclude on a positive note: global solidarity may be conceptualized to helpfully address global health inequity, to the extent that personal and transnational interdependence are enough to motivate national governments into action.

    Full Text Available The objective of this paper is our intention to present what are the main connections between globalization and international security. In terms of global security we can perceive the globalization as a process by which global state is represented by the UN, with a single world system, represented by major security organizations and with global effects. We will present from the beginning the main theoretical aspects that define the phenomenon of globalization, and then our contribution in assessing the implications of this phenomenon on the regional and global security. The results of our research are materialized in the last part of the paper. They emphasize the personal assessments on how the phenomenon of globalization has direct effect on global security. When talking about government, we think of norms, rules and decisionmaking procedures in the management of international life. The value that we add to the new scientific interpretation of the definition of globalization is represented, primarily, by the valuable bibliographic used resources and the original approach on the concept that refers to the links between globalization and security. This article may be, at any time, a starting point in an interesting research direction in the field of global security.

  16. A global HMX decomposition model

    Energy Technology Data Exchange (ETDEWEB)

    Hobbs, M.L.

    1996-12-01

    HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) decomposes by competing reaction pathways to form various condensed and gas-phase intermediate and final products. Gas formation is related to the development of nonuniform porosity and high specific surface areas prior to ignition in cookoff events. Such thermal damage enhances shock sensitivity and favors self-supported accelerated burning. The extent of HMX decomposition in highly confined cookoff experiments remains a major unsolved experimental and modeling problem. The present work is directed at determination of global HMX kinetics useful for predicting the elapsed time to thermal runaway (ignition) and the extent of decomposition at ignition. Kinetic rate constants for a six step engineering based global mechanism were obtained using gas formation rates measured by Behrens at Sandia National Laboratories with his Simultaneous Modulated Beam Mass Spectrometer (STMBMS) experimental apparatus. The six step global mechanism includes competition between light gas (H[sub 2]Awe, HCN, CO, H[sub 2]CO, NO, N[sub 2]Awe) and heavy gas (C[sub 2]H[sub 6]N[sub 2]Awe and C[sub 4]H[sub 10]N0[sub 2]) formation with zero order sublimation of HMX and the mononitroso analog of HMX (mn-HMX), C[sub 4]H[sub 8]N[sub 8]Awe[sub 7]. The global mechanism was applied to the highly confined, One Dimensional Time to eXplosion (ODTX) experiment and hot cell experiments by suppressing the sublimation of HMX and mn-HMX. An additional gas-phase reaction was also included to account for the gas-phase reaction of N[sub 2]Awe with H[sub 2]CO. Predictions compare adequately to the STMBMS data, ODTX data, and hot cell data. Deficiencies in the model and future directions are discussed.

  17. In search of global leaders.

    Green, Stephen; Hassan, Fred; Immelt, Jeffrey; Marks, Michael; Meiland, Daniel

    2003-08-01

    For all the talk about global organizations and executives, there's no definitive answer to the question of what we really mean by "global." A presence in multiple countries? Cultural adaptability? A multilingual top team? We asked four CEOs and the head of an international recruiting agency--HSBC's Stephen Green, Schering-Plough's Fred Hassan, GE's Jeffrey-lmmelt, Flextronics's Michael Marks, and Egon Zehnder's Daniel Meiland--to tell us what they think. They share some common ground. They all agree, for example, that the shift from a local to a global marketplace is irreversible and gaining momentum. "We're losing sight of the reality of globalization. But we should pay attention, because national barriers are quickly coming down", Daniel Meiland says. "If you look ahead five or ten years, the people with the top jobs in large corporations ... will be those who have lived in several cultures and who can converse in at least two languages." But the CEOs also disagree on many issues--on the importance of overseas assignments, for instance, and on the degree to which you need to adhere to local cultural norms. Some believe strongly that the global leader should, as a prerequisite to the job, live and work in other countries. As Stephen Green put it, "If you look at the executives currently running [HSBC's] largest businesses, all of them have worked in more than one, and nearly all in more than two, major country markets." Others downplay the importance of overseas assignments. "Putting people in foreign settings doesn't automatically imbue new attitudes, and it is attitudes rather than experiences that make a culture global," says Fred Hassan. The executives' essays capture views that are as diverse and multidimensional as the companies they lead.

A 1776 letter from Alessandro Volta to Father Campi described the first experiments on flammable "air" released by shallow sediments in Lake Maggiore (Wolfe, 1996; King, 1992). The first quantitative measurements of CH4, both involving combustion and gravimetric determination of trapped oxidation products, were reported in French by Boussingault and Boussingault, 1864 and Gautier (1901), who reported CH4 concentrations of 10 ppmv and 0.28 ppmv (seashore) and 95 ppmv (Paris), respectively. The first modern measurements of atmospheric CH4 were the infrared absorption measurements of Migeotte (1948), who estimated an atmospheric concentration of 2.0 ppmv. Development of gas chromatography and the flame ionization detector in the 1950s led to observations of vertical CH4 distributions in the troposphere and stratosphere, and to establishment of time-series sampling programs in the late 1970s. Results from these sampling programs led to suggestions that the concentration of CH4, as that of CO2, was increasing in the atmosphere. The possible role of CH4 as a greenhouse gas stimulated further research on CH4 sources and sinks. Methane has also been of interest to microbiologists, but findings from microbiology have entered the larger context of the global CH4 budget only recently.Methane is the most abundant hydrocarbon in the atmosphere. It plays important roles in atmospheric chemistry and the radiative balance of the Earth. Stratospheric oxidation of CH4 provides a means of introducing water vapor above the tropopause. Methane reacts with atomic chlorine in the stratosphere, forming HCl, a reservoir species for chlorine. Some 90% of the CH4 entering the atmosphere is oxidized through reactions initiated by the OH radical. These reactions are discussed in more detail by Wofsy (1976) and Cicerone and Oremland (1988), and are important in controlling the oxidation state of the atmosphere

    To evaluate obstetrics and gynecology resident interest and participation in global health experiences and elucidate factors associated with resident expectation for involvement. A voluntary, anonymous survey was administered to U.S. obstetrics and gynecology residents before the 2015 Council on Resident Education in Obstetrics and Gynecology in-training examination. The 23-item survey gathered demographic data and queried resident interest and participation in global health. Factors associated with resident expectation for participation in global health were analyzed by Pearson χ tests. Of the 5,005 eligible examinees administered the survey, 4,929 completed at least a portion of the survey for a response rate of 98.5%. Global health was rated as "somewhat important" or "very important" by 96.3% (3,761/3,904) of residents. "Educational opportunity" (69.2%) and "humanitarian effort" (17.7%) were cited as the two most important aspects of a global health experience. Residents with prior global health experience rated the importance of global health more highly and had an increased expectation for future participation. Global health electives were arranged by residency programs for 18.0% (747/4,155) of respondents, by residents themselves as an elective for 44.0% (1,828/4,155), and as a noncredit experience during vacation time for 36.4% (1,514/4,155) of respondents. Female gender, nonpartnered status, no children, prior global health experience, and intention to incorporate global health in future practice were associated with expectations for a global health experience. Most obstetrics and gynecology residents rate a global health experience as somewhat or very important, and participation before or during residency increases the perceived importance of global health and the likelihood of expectation for future participation. A majority of residents report arranging their own elective or using vacation time to participate, suggesting that residency programs have

    The oceans are an equal partner with the atmosphere in the global climate system. The World Ocean Circulation Experiment is presently being implemented to improve ocean models that are useful for climate prediction both by encouraging more model development but more importantly by providing quality data sets that can be used to force or to validate such models. WOCE is the first oceanographic experiment that plans to generate and to use multiparameter global ocean data sets. In order for WOCE to succeed, oceanographers must establish and learn to use more effective methods of assembling, quality controlling, manipulating and distributing oceanographic data.

  2. How Global is Global Civil Society?

    2015-08-01

    Full Text Available In recent times the concept of global civil society has made its appearance on national and international intellectual, as well as political agendas, in a major way. It is of some interest that two other concepts, both of which call for transcendence of national boundaries in precisely the same way as global civil society does, have also made their appearance on the scene of intellectual debates at roughly the same time: the concept of cosmopolitanism and that of transnational justice. All three concepts have dramatically expanded the notion of commitment to one’s fellow beings beyond the nation state. And all three concepts have extended critiques of policies that violate the dignity of human beings from national governments to the practices of inter-national institutions such as the World Bank, the International Monetary Fund, and the World Trade Forum. In sum the inter-related concepts of global civil society, cosmopolitanism, and transnational justice have greatly enlarged the traditional domain of political theory. And yet for any political theorist who is acutely conscious of the phenomenon of power, these concepts are not unproblematic. For the practices of global civil society may just reinforce the intellectual and the moral power of the West over the postcolonial world. This is particularly true of say global human rights organizations. This paper will attempt to raise some questions of the concept and the practices of global civil society from the perspective of the countries of the South.

    A novel algorithm of global motion estimation is proposed. First, through Gabor wavelet transform (GWT), a kind of energy distribution of image is obtained and checkpoints are selected according to a probability decision approach proposed. Then, the initialized motion vectors are obtained via a hierarchal block-matching based on these checkpoints.Finally, by employing a 3-parameter motion model, precise parameters of global motion are found. From the experiment, the algorithm is reliable and robust.

  13. Unconscious local motion alters global image speed.

    Directory of Open Access Journals (Sweden)

    Sieu K Khuu

    Full Text Available Accurate motion perception of self and object speed is crucial for successful interaction in the world. The context in which we make such speed judgments has a profound effect on their accuracy. Misperceptions of motion speed caused by the context can have drastic consequences in real world situations, but they also reveal much about the underlying mechanisms of motion perception. Here we show that motion signals suppressed from awareness can warp simultaneous conscious speed perception. In Experiment 1, we measured global speed discrimination thresholds using an annulus of 8 local Gabor elements. We show that physically removing local elements from the array attenuated global speed discrimination. However, removing awareness of the local elements only had a small effect on speed discrimination. That is, unconscious local motion elements contributed to global conscious speed perception. In Experiment 2 we measured the global speed of the moving Gabor patterns, when half the elements moved at different speeds. We show that global speed averaging occurred regardless of whether local elements were removed from awareness, such that the speed of invisible elements continued to be averaged together with the visible elements to determine the global speed. These data suggest that contextual motion signals outside of awareness can both boost and affect our experience of motion speed, and suggest that such pooling of motion signals occurs before the conscious extraction of the surround motion speed.

  14. Global warming without global mean precipitation increase?

    Science.gov (United States)

    Salzmann, Marc

    2016-06-01

    Global climate models simulate a robust increase of global mean precipitation of about 1.5 to 2% per kelvin surface warming in response to greenhouse gas (GHG) forcing. Here, it is shown that the sensitivity to aerosol cooling is robust as well, albeit roughly twice as large. This larger sensitivity is consistent with energy budget arguments. At the same time, it is still considerably lower than the 6.5 to 7% K(-1) decrease of the water vapor concentration with cooling from anthropogenic aerosol because the water vapor radiative feedback lowers the hydrological sensitivity to anthropogenic forcings. When GHG and aerosol forcings are combined, the climate models with a realistic 20th century warming indicate that the global mean precipitation increase due to GHG warming has, until recently, been completely masked by aerosol drying. This explains the apparent lack of sensitivity of the global mean precipitation to the net global warming recently found in observations. As the importance of GHG warming increases in the future, a clear signal will emerge.

  20. Globalization, culture and psychology.

    Science.gov (United States)

    Melluish, Steve

    2014-10-01

    This article outlines the cultural and psychological effects of globalization. It looks at the impact of globalization on identity; ideas of privacy and intimacy; the way we understand and perceive psychological distress; and the development of the profession of psychology around the world. The article takes a critical perspective on globalization, seeing it as aligned with the spread of neoliberal capitalism, a tendency towards cultural homogenization, the imposition of dominant 'global north' ideas and the resultant growing inequalities in health and well-being. However, it also argues that the increased interconnectedness created by globalization allows for greater acknowledgement of our common humanity and for collective efforts to be developed to tackle what are increasingly global problems. This requires the development of more nuanced understandings of cultural differences and of indigenous psychologies.

  3. Globalization in the post - colonial world

    Korobeynikova Larisa A.

    2016-01-01

    Full Text Available The paper presents a new interpretation of globalization within the boundaries of the author’s concept of soft globalization, which exploits a normatively attractive alternative to the concept of the Empire. It is argued here that the conditions of development of contemporary post - colonial world communities do not require any unification in the form of the Empire, but instead the creation of a non repressive mechanism of social regulation - the implementation of a form of soft globalization, a globalization with a mental form are expedient here. Historically, globalization occurred in a strict material(i.e. economical and military form that prompted the conditions for the evolution of civilization as the Empire: a case in which the development of the world occurs under the power of a single dominating state. Imperialistic politics leads to colonial politics formation. The history of the phenomena of civilization shows many instances of Empire globalization. Globalization in the Empire form was already observed at the time of the Roman Empire. At this time processes of development inside the Empire were manifestations of globalization in its highest cultural shape. But ancient Rome was also a social and political experiment that acquired the attributes of a purely material globalization in the end, and historically brought about the irreversible crash of the Roman Empire itself. Contemporary fluctuations referring to the process of globalization can be registered in the US’s attempts of material domination inside this or that existing case of civilization, which causes colonialism appearance. The main idea stressed in the paper is that only a mental globalization could succeed in the end.

After refusing the arguments against both of the libertarianism and the statism, and after showing the critics both to the approach to the language of human rights and to the poggean proposal to reduce the duties of global justice to negative moral duties, I defend the need to use a sufficiency approach to global justice based in positive moral duties to face the severity and the moral urgency of the global inequalities of health.

    Directory of Open Access Journals (Sweden)

    Michele Marsonet

    2017-01-01

    Globalization is frequently discussed as a counterpoint to national sovereignty. It is commonly asserted that globalization has eroded national sovereignty or that it has rendered borders obsolete. In particular, it is asserted that, in a globalized world economy, governments have no alternative but to adopt neoliberal economic policies of privatization, deregulation and reductions in public expenditure. However, in the contest between social democracy and neoliberal globalization, the nation—state per se is only marginally relevant. The crucial issue is whether policy will respond to the wishes of a democratic electorate, or be tightly constrained by the ‘Golden Straightjacket’ of international financial markets.

    Full Text Available Something like "global Keynesianism" or "transnational socialism" has been mentioned as a desirable alternative to global neoliberalism (Redmond 1997. However, a definition of this kind of global Keynesianism is hard to find. Many leftists tend to associate Keynesianism with corporate power. However, there are also numerous other leftists who view this differently. For example, a member of parliament for the German Green Party stated in a recent interview that "a reformist party today has to be a left-Keynesian party which contradicts the logic of capital" (Ebermann 1998. A number of scholars from several countries, including Canada, pursue post-Keynesian-ism, in the sense of left-Keynesian economics (e.g., Seccareccia 1991. How-ever, available left-Keynesian literature, as I see it, is lacking a world-system perspective. I am trying in this article to synthesize the two perspectives-namely, left-Keynesianism and world-system theory, leading to a perspective of global left-Keynesianism. This leftist global Keynesianism can, perhaps, be described as an approach to economics which emphasizes responsible public management of economic problems in a world-system context. Common themes in global Keynesianism include the importance of public management, democratic politics, the mixed economy, global income distribution, the management of global demand, investment and money, ecological sustainability and the importance of multiple levels of public management-local, national, regional and global.

  17. Globalization, Class and Culture in Global Systems

    Directory of Open Access Journals (Sweden)

    Jonathan Friedman

    2015-08-01

    Full Text Available The work of Immanuel Wallerstein has been criticized by certain anthropologists for not having taken culture into proper account. He has been accused of the sin of political economy, a not uncommon accusation, a re?ex of the 80’s and post-80’s anthropological jargon that might ?nally today be exhausted. Years earlier a number of social scientists were engaged in a critical assessment of the social sciences from a distinctively global perspective. Wallerstein, Frank and others were at the forefront of this critique which had a powerful impact on anthropology. The global perspective was not a mere addition to anthropological knowledge, not a mere of extension of the use of the culture concept, i.e. before it was local and now it is global, before culture stood still, but now in the global age, it ?ows around the world. It was a more fundamental critique, or at least it implied a more fundamental critique. This critique could only be attained from a perspective in which the very concept of society was re-conceived as something very different, as a locus constructed within a historical force ?eld which was very much broader than any particular politically de?ned unit.

  19. Future Global Cryosphere: Impacts of Global Warming

    Science.gov (United States)

    Gan, T. Y.; Barry, R. G.

    2014-12-01

    In recent years, the Earth is undergoing potentially rapid changes in all cryospheric components, including Arctic sea ice shrinkage, mountain glacier recession, thawing permafrost, diminishing snow cover, and accelerated melting of the Greenland ice sheet. This has significant implications for global climate, hydrology, water resources, and global sea level. Physical evidences of changes observed in the cryosphere are: (a) Duration of ice cover of rivers and lakes in high latitudes of N. H. decreased by about two weeks over the 20th Century; (b) Significant retreat of glaciers world wide during the 20th Century; (c) Thinning of Arctic sea-ice extent and thickness by about 40% in late summer in recent decades, with the minimum sea ice concentration mapped by the SSM/I sensor of NASA in 2007; (d) Snow cover decreased in area by about 10% since global observations by satellites began in the late 1960s, in various places of the Northern Hemisphere; (e) In North America, snow water equivalent decreased by about 10mm since observations by passive microwave sensors began in the late 1970s; (f) Degradations of permafrost have been detected in some parts of the polar and sub-polar regions, and (g) The total 20th Century global average sea level rise was about 0.17m, likely due to decline in glaciers, snow, ice sheets, and losses from Greenland and Antarctica ice. Next, projected changes to the Cryosphere: northern hemisphere snow cover, avalanches, land ice, permafrost, freshwater ice, and sea ice changes, are presented.

  20. BUSINESS GLOBALIZATION: TRANSNATIONAL CORPORATIONS AND GLOBAL COMPETITION

    Directory of Open Access Journals (Sweden)

    DIMA Stela

    2013-06-01

    Full Text Available The purpose of this paper is to introduce business globalization and the main globalization factors which, under the current stage, are transnational corporations. Globalization is the result of the pressure put by companies which, in turn, are under the close “magnifier” of all the involved factors (the so-called “stakeholders”. The market and the determining forces are not influenced by a political attitude nowadays marking globalization, but rather the political decisions have followed the course of economic evolutions, a trend that has always been provided by multinational corporations. In order to successfully follow up their activity, companies initiate new businesses, selling or deleting from their portfolio businesses or divisions with a decreasing tendency. Also, companies give up old rules and structures adopting new decision-making processes, control systems and mental patterns. Corporations must learn to become dynamic just like the market, if they wish to maintain, on the long run, a superior rate of income.

How can transnational firms organize CR so as to maximize efficiencies from globalization and to minimize the fragmentation of corporate organizational cultures? Bartlett and Ghoshal (1989) provide...... that it is important for companies to define a common set of organizational norms. In addition, CR need to be sensitive to local institutional contexts, but learning from subsidiary experience is important and lends itself to standardization and replication of initiatives across market contexts....

  20. European Integration and Globalization

    Directory of Open Access Journals (Sweden)

    Diana Bobica

    2010-06-01

    Full Text Available According to many, the term globalization is able to explain any phenomenon whatsoever, be it positive or negative, that takes place within the global social system. It seems like a sort of magical formula, which is to be found in the speeches of all sorts of people, be they economists, politicians, businessmen or sociologists. However this magical formula of globalization has its limitations, since it encompasses a certain amount of quibbling, beyond which not many can pass. In the context of globalization there appears the question on its role in the process of European integration. Is European integration a part of this global process or, quite on the contrary, does it present certain distinctive features, as it moulds itself differently from the globalization phenomenon? A clear-cut answer seems difficult because of the various aspects involved. Not only the general phenomenon of globalization, but also the economic integration on European level is based on the liberalization of markets and on the opening of national economies towards the exterior,having as direct consequence the intensification of trade exchanges. If from a global point of view one may talk of a market fundamentalism in that the market principles know no boundary, European integration on the other hand implies not only market economy, but also a guided and monitored action of Member Statesaccording to the needs of the whole entity, also taking into consideration - as far as possible – all aspects and consequences on social level.
