    Electric propulsion is a method of creating thrust for space exploration that requires less propellant than traditional chemical rockets by producing much higher exhaust velocities, and subsequently costing less. Currently, such forms of propulsion are unable to generate the vast amounts of thrust that traditional thrusters do, thus research is being done in the area. The focus of this project is Hall Effect thrusters, a specific type of ion propulsion. The distinctive feature of these thrusters are magnets which capture the electrons from the cathode. These electrons ionize the propellant gas and then interact with the present electric field to accelerate the resulting ions, generating thrust. The objectives of this project include building two Hall thrusters with different magnet configurations, collecting performance data, and testing with a Faraday probe that directly measures current density. The first magnet configuration will be a conventional Hall Effect thruster arrangement, while the second thruster's magnets are arranged to create a significantly stronger magnetic field. The performance data and Faraday probe results will be used to determine the level of improvement between the thrusters. The goal is to integrate a Hall Effect propulsion system into the university's Cube-Sat program.

    Enabling effective data use and re-use in scientific investigations relies heavily not only on data availability but also on efficient data sharing discovery. The CUAHSI led Hydrological Information Systems (HIS) and supporting products have paved the way to efficient data sharing and discovery in the hydrological sciences. Based on the CUAHSI-HIS framework concepts for hydrologic data sharing we developed a unique system devoted to the George Mason University scientific community to support university wide data sharing and discovery as well as real time data access for extreme events situational awareness. The internet-based system will provide an interface where the researchers will input data collected from the measurement stations and present them to the public in form of charts, tables, maps, and documents. Moreover, the system is developed in ASP.NET MVC 4 using as Database Management System, Microsoft SQL Server 2008 R2, and hosted by Amazon Web Services. Currently the system is supporting the Mason Watershed Project providing historical hydrological, atmospheric and water quality data for the campus watershed and real time flood conditions in the campus. The system is also a gateway for unprecedented data collection of hurricane storm surge hydrodynamics in coastal wetlands in the Chesapeake Bay providing not only access to historical data but recent storms such as Hurricane Arthur. Future research includes coupling the system to a real-time flood alert system on campus, and besides providing data on the World Wide Web, to foment and provide a venue for interdisciplinary collaboration within the water scientists in the region.

    The quest for universal memory is driving the rapid development of memories with superior all-round capabilities in non-volatility, high speed, high endurance and low power. Phase-change materials are highly promising in this respect. However, their contradictory speed and stability properties present a key challenge towards this ambition. We reveal that as the device size decreases, the phase-change mechanism changes from the material inherent crystallization mechanism (either nucleation- or growth-dominated), to the hetero-crystallization mechanism, which resulted in a significant increase in PCRAM speeds. Reducing the grain size can further increase the speed of phase-change. Such grain size effect on speed becomes increasingly significant at smaller device sizes. Together with the nano-thermal and electrical effects, fast phase-change, good stability and high endurance can be achieved. These findings lead to a feasible solution to achieve a universal memory.

  18. Enabling Mobile Communications for the Needy: Affordability Methodology, and Approaches to Requalify Universal Service Measures

    Directory of Open Access Journals (Sweden)

    Louis-Francois PAU

    2009-01-01

    Full Text Available This paper links communications and media usage to social and household economics boundaries. It highlights that in present day society, communications and media are a necessity, but not always affordable, and that they furthermore open up for addictive behaviors which raise additional financial and social risks. A simple and efficient methodology compatible with state-of-the-art social and communications business statistics is developed, which produces the residual communications and media affordability budget and ultimately the value-at-risk in terms of usage and tariffs. Sensitivity analysis provides precious information on bottom-up communications and media adoption on the basis of affordability. This approach differs from the regulated but often ineffective Universal service obligation, which instead of catering for individual needs mostly addresses macro-measures helping geographical access coverage (e.g. in rural areas. It is proposed to requalify the Universal service obligations on operators into concrete measures, allowing, with unchanged funding, the needy to adopt mobile services based on their affordability constraints by bridging the gap to a standard tariff. Case data are surveyed from various countries. ICT policy recommendations are made to support widespread and socially responsible communications access.

    Background Disability inclusion in the curricula of higher education institutions contributes to socially responsive graduates with a capacity to address the cross-cutting issue of disability in development. This article discusses a study conducted at the University of Cape Town (UCT), South Africa, to explore disability inclusion. Methodology An instrumental case study approach was adopted and a thematic analysis of data was done. Findings Academic staff found a variety of ways to include disability, such as discussions in class, practice and service learning, but mainly as part of disciplinary requirements. Including disability as an issue of social justice stems mostly from the personal interest of staff, and is done in an ad hoc manner. Conclusion Disability should be valued, and integrated into the curriculum in a structured manner as a perspective on diversity with which to interrogate our beliefs about ourselves and society. Theorising on disability is needed, as well as the unique perspectives that emerge across interdisciplinary boundaries, especially within the African context. PMID:28730025

  4. Enabling Effective Problem-oriented Research for Sustainable Development

    2012-12-01

    Full Text Available Environmental problems caused by human activities are increasing; biodiversity is disappearing at an unprecedented rate, soils are being irreversibly damaged, freshwater is increasingly in short supply, and the climate is changing. To reverse or even to reduce these trends will require a radical transformation in the relationship between humans and the natural environment. Just how this can be achieved within, at most, a few decades is unknown, but it is clear that academia must play a crucial role. Many believe, however, that academic institutions need to become more effective in helping societies move toward sustainability. We first synthesize current thinking about this crisis of research effectiveness. We argue that those involved in producing knowledge to solve societal problems face three particular challenges: the complexity of real-world sustainability problems, maintaining impartiality when expert knowledge is used in decision making, and ensuring the salience of the scientific knowledge for decision makers. We discuss three strategies to meet these challenges: conducting research in interdisciplinary teams, forming research partnerships with actors and experts from outside academia, and framing research questions with the aim of solving specific problems (problem orientation. However, we argue that implementing these strategies within academia will require both cultural and institutional change. We then use concepts from transition management to suggest how academic institutions can make the necessary changes. At the level of system optimization, we call for: quality criteria, career incentives, and funding schemes that reward not only disciplinary excellence but also achievements in inter-/transdisciplinary work; professional services and training through specialized centers that facilitate problem-oriented research and reciprocal knowledge exchange with society; and the integration of sustainability and inter

  5. Universality of the Hawking effect

    International Nuclear Information System (INIS)

    Unruh, William G.; Schuetzhold, Ralf

    2005-01-01

    Addressing the question of whether the Hawking effect depends on degrees of freedom at ultrahigh (e.g., Planckian) energies/momenta, we propose three rather general conditions on these degrees of freedom under which the Hawking effect is reproduced to lowest order. As a generalization of Corley's results, we present a rather general model based on nonlinear dispersion relations satisfying these conditions together with a derivation of the Hawking effect for that model. However, we also demonstrate counter-examples, which do not appear to be unphysical or artificial, displaying strong deviations from Hawking's result. Therefore, whether real black holes emit Hawking radiation remains an open question and could give nontrivial information about Planckian physics

  6. Enabling HST UV Exploration of the Low Surface Brightness Universe: A Pilot Study with the WFC3 X Filter Set

    Science.gov (United States)

    Thilker, David

    2017-08-01

    We request 17 orbits to conduct a pilot study to examine the effectiveness of the WFC3/UVIS F300X filter for studying fundamental problems in star formation in the low density regime. In principle, the broader bandpass and higher throughput of F300X can halve the required observing time relative to F275W, the filter of choice for studying young stellar populations in nearby galaxies. Together with F475W and F600LP, this X filter set may be as effective as standard UVIS broadband filters for characterizing the physical properties of such populations. We will observe 5 low surface brightness targets with a range of properties to test potential issues with F300X: the red tail to 4000A and a red leak beyond, ghosts, and the wider bandpass. Masses and ages of massive stars, young star clusters, and clumps derived from photometry from the X filter set will be compared with corresponding measurements from standard filters. Beyond testing, our program will provide the first sample spanning a range of LSB galaxy properties for which HST UV imaging will be obtained, and a glimpse into the ensemble properties of the quanta of star formation in these strange environments. The increased observing efficiency would make more tractable programs which require several tens to hundreds of orbits to aggregate sufficient numbers of massive stars, young star clusters, and clumps to build statistical samples. We are hopeful that our pilot observations will broadly enable high-resolution UV imaging exploration of the low density frontier of star formation while HST is still in good health.

    We present the universal one-loop effective action for all operators of dimension up to six obtained by integrating out massive, non-degenerate multiplets. Our general expression may be applied to loops of heavy fermions or bosons, and has been checked against partial results available in the literature. The broad applicability of this approach simplifies one-loop matching from an ultraviolet model to a lower-energy effective field theory (EFT), a procedure which is now reduced to the evaluation of a combination of matrices in our universal expression, without any loop integrals to evaluate. We illustrate the relationship of our results to the Standard Model (SM) EFT, using as an example the supersymmetric stop and sbottom squark Lagrangian and extracting from our universal expression the Wilson coefficients of dimension-six operators composed of SM fields.

    2013-04-01

    Full Text Available Lecturers are fully occupied with many tasks including preparing teaching materials, exam papers, lab sheets, markings, research, and administrative support tasks required of them to maintain high standard teaching delivery and good quality management system in the school. Aside from these, they are now required to do intensive Outcome-Based Education (OBE assessments, and Continual Quality Improvement (CQI planning and implementation. An automated OBE assessment tool is therefore required to ease the burden among the lecturers and provide a standard method of assessment. To assist in this process, this paper presents a blueprint of a software-enabled quantitative measurement of the Learning Outcomes (LO and the Programme Outcomes (PO in the module level. The blueprint consists of macro-enabled worksheets that automatically calculate the students’ individual LO and PO attainments based on their respective module assessment marks whereby the lecturer only need to key-in the subject details of assessments-LO mapping, LO-PO mapping and the students’ assessment marks. Once the marks are in place, LO and PO attainments are calculated automatically to provide the corresponding bar charts based on the individual attainments of the students. A LO or a PO is said to be attained when the number of students achieved the Key Performance Index (KPI set by the department. The results will then be used by the lecturer to prepare an annual module review and prepare a CQI plan for the next semester.

    Full Text Available Total quality management (TQM is a unified management approach that concentrates on the consecutive improvement of processes, products, and methods to surpass client expectations. This paper aims to highlight the advantages of implementing TQM in the airline industry by examining the key enablers of TQM. This study was based on a research model including six factors that were found to have a profound influence in implementing TQM. The data needed for the study was collected with the aid of questionnaires and secondary sources. The study discovered that procedures, policies, and a culture of knowledge transfer were the most significant enablers of successful TQM initiatives in Royal Jet Airways. In order to effectively implement TQM, the study suggests that management should offer appropriate recognition and rewards to employees. This will motivate them to adopt and practice TQM initiatives. Apart from that, management should also arrange seminars or workshops to accustom the employees to the basic procedures and objectives of effective TQM.

    The Universal Health Coverage (UHC) is at the center of the 2030 Sustainable Development Goals agenda. In this study, the authors made an evaluation of the patient health coverage indicators in eight Burundian hospitals from 2011 to 2016. The relevant UHC indicators were calculated on the basis of patient administrative and health insurance data, collected via OpenClinic GA, an information and communication technology (ICT) supported health management information system (HMIS). The results show that the patient health services coverage rate was 70.8% for inpatients and 46.0% for outpatients. The patient health services payment rate as the proportion of total health service costs was above the 25% threshold recommended by WHO for inpatients (30.2%) and for outpatients (43.1%). The patient out-of-pocket payment was below the threshold of 180USD per patient per year for public hospitals. This study demonstrated the possibility to assess the degree of UHC in developing countries, by using routine data extracted automatically from the electronic HMIS.

    Galaxies were surprisingly dusty in the early Universe, with more than half of the light emitted from stars being absorbed by dust within the system and re-radiated into far infrared (FIR, ~50-150μm) wavelengths. Dusty star forming galaxies (DSFGs) dominate the co-moving star formation rate density of the Universe that peaks around redshift, z~2, making it compelling to study them in rest frame FIR bands. From galaxies at z > 1, the FIR line emission from abundant ions like [O III], [C II] and [N II], are redshifted into the short sub-mm telluric windows. My thesis work is based on building and deploying the 2nd Generation Redshift (z) and Early Universe Spectrometer (ZEUS-2), a long-slit, echelle grating spectrometer optimized to study broad (Δv = 300km/s) spectral lines from galaxies in the 200-650µm telluric windows using TES bolometers. These far-IR lines being extinction free and major coolants of the gas heated by (young) massive stars, are powerful probes of the physical conditions of the gas and the stellar radiation field. I present results from our survey of the [O III] 88µm line in galaxies at redshift, z ~ 2.8 to 4.6, with ZEUS-2 at the Atacama Pathfinder Experiment (APEX) Telescope. To interpret our observations along with ancillary data from optical to radio facilities, we apply photoionization models for HII regions and Photo Dissociation Region (PDR) models and confirm that the galaxies host substantial ongoing obscured star formation. The presence of doubly ionized oxygen suggests hard radiation fields and hence, elevated ionization parameters that can only be accounted for by a large population of massive stars formed during the ongoing starburst, that contribute a large fraction of the infrared luminosity. This study highlights the use of FIR line emission to trace the assembly of current day massive galaxies, conditions of star formation and details of their stellar populations. The construction and operation of ZEUS-2 were funded by NSF ATI

    The modeling and analysis of the dynamics of complex systems often requires to employ non-Markovian stochastic processes. While there is a clear and well-established mathematical definition for non-Markovianity in the case of classical systems, the extension to the quantum regime recently caused a vivid debate, leading to many different proposals for the characterization and quantification of memory effects in the dynamics of open quantum systems. Here, we derive a mathematical representation for the non-Markovianity measure based on the exchange of information between the open system and its environment, which reveals the locality and universality of non-Markovianity in the quantum state space and substantially simplifies its numerical and experimental determination. We further illustrate the application of this representation by means of an all-optical experiment which allows the measurement of the degree of memory effects in a photonic quantum process with high accuracy.

    Full Text Available The goal of this study is to analyze the effect of the enabling perception of costing systems by managers in the performance of their tasks, mediated by the intensity in of use of these costing systems and the level of psychological empowerment. The research was carried out through a survey of 62 companies listed in the Perfil das Empresas com Projetos Aprovados ou em Implantação na Zona Franca de Manaus Profile of Companies, in 2014. With a view to analyzing the hypotheses replicated from Mahama’s and Cheng’s (2013 study, the Structural Equations Modeling technique wasused. The research results show that the managers’ enabling perception of costing systems does not affect their  intensity of use, but it impacts on psychological empowerment, and this is directly reflected in the performance of tasks, indicating that the greater the empowerment, the better manager performance will be. It isconcluded that the model partially supports the relationships delineated and that the antecedents related to the costing systems require further study.

    Full Text Available Abstract Background In India, since the 1990s, there has been a burgeoning of NGOs involved in providing primary health care. This has resulted in a complex NGO-Government interface which is difficult for lone NGOs to navigate. The Uttarakhand Cluster, India, links such small community health programs together to build NGO capacity, increase visibility and better link to the government schemes and the formal healthcare system. This research, undertaken between 1998 and 2011, aims to examine barriers and facilitators to such linking, or clustering, and the effectiveness of this clustering approach. Methods Interviews, indicator surveys and participant observation were used to document the process and explore the enablers, the barriers and the effectiveness of networks improving community health. Results The analysis revealed that when activating, framing, mobilising and synthesizing the Uttarakhand Cluster, key brokers and network players were important in bridging between organisations. The ties (or relationships that held the cluster together included homophily around common faith, common friendships and geographical location and common mission. Self interest whereby members sought funds, visibility, credibility, increased capacity and access to trainings was also a commonly identified motivating factor for networking. Barriers to network synthesizing included lack of funding, poor communication, limited time and lack of human resources. Risk aversion and mistrust remained significant barriers to overcome for such a network. Conclusions In conclusion, specific enabling factors allowed the clustering approach to be effective at increasing access to resources, creating collaborative opportunities and increasing visibility, credibility and confidence of the cluster members. These findings add to knowledge regarding social network formation and collaboration, and such knowledge will assist in the conceptualisation, formation and success of

    Emergent universe model is presented in general theory of relativity with isotropic fluid in addition to viscosity. We obtain cosmological solutions that permit emergent universe scenario in the presence of bulk viscosity that are described by either Eckart theory or Truncated Israel Stewart (TIS) theory. The stability of the solutions are also studied. In this case, the emergent universe (EU) model is analyzed with observational data. In the presence of viscosity, one obtains emergent universe scenario, which however is not permitted in the absence of viscosity. The EU model is compatible with cosmological observations.

    Chalhoub, Michel S.

    The present paper studies the relationship between social networks enabled by technological advances in social software, and overall business performance. With the booming popularity of online communication and the rise of knowledge communities, businesses are faced with a challenge as well as an opportunity - should they monitor the use of social software or encourage it and learn from it? We introduce the concept of user-autonomy and user-fun, which go beyond the traditional user-friendly requirement of existing information technologies. We identified 120 entities out of a sample of 164 from Mediterranean countries and the Gulf region, to focus on the effect of social exchange information systems in thought leadership.

    We report the universal behavior of inverse magnetocaloric effect (IMCE) in antiferromagnetic materials. In contrast to the universal behavior of conventional magnetocaloric effect often observed in ferromagnetic systems, a phenomenological universal master curve can be constructed to describe the temperature dependence of magnetic entropy change for IMCE without rescaling the temperature axis. The proposed universal curve method allows extrapolating the magnetic entropy change of an IMCE material, which would be imperative to judge its suitability in actual magnetic refrigeration devices.

    An enabling environment is believed to have significant and critical effects on HIV and AIDS program implementation and desired outcomes. This paper estimates the paths, directionality, and direct and indirect associations between critical enablers with antiretroviral treatment (ART) coverage and to AIDS-related mortality. Frameworks that consider the role of enablers in HIV and AIDS programs were systematically reviewed to develop a conceptual model of interaction. Measurements for constructs of the model were pooled from the latest publicly available data. A hypothetical model, including latent/unobserved factors and interaction of enablers, program activities and outcomes, was analyzed cross-sectionally with structural equation modeling. Coefficients of the model were used to estimate the indirect associations of enablers to treatment coverage and the subsequent associated impact on AIDS related mortality. The model's fit was adequate (RMSEA = 0·084, 90% CI [0·062, 0·104]) and the indirect effects of enablers on outcomes were measured. Enablers having significant associations with increased ART coverage were social/financial protection, governance, anti-discrimination, gender equality, domestic AIDS spending, testing service delivery, and logistics. Critical enablers are significantly correlated to outcomes like ART coverage and AIDS related mortality. Even while this model does not allow inference on causality, it provides directionality and magnitude of the significant associations.

    2018-02-26

    The purpose of this study is to systematically review published evidence regarding the development, use and effectiveness of assistive devices and technologies that enable internet access for individuals who are deafblind. Eight electronic research databases (CINAHL, Embase, Engineering Village MEDLINE, PsycINFO, PubMed, Cochrane Library, and Web of Science) and three clinical trials registries (ISRCTN Registry, WHO ICTRP, and ClinicalTrials,gov) were searched. Seven articles met the inclusion criteria for this systematic review. The assistive technologies described were in the preliminary stages of development, with only three of the technologies having undergone any testing. The effectiveness of all seven assistive technologies was quantified in this review based on the proposed impacts of internet access on the domains of the World Health Organization's International Classification of Functioning, Disability and Health framework. Internet access technologies for individuals with deafblindness are in the early stages of development and are targeted towards specific functions of the internet. It is imperative that future device development and evaluation seek input from persons who are deafblind. There is also a need to address the gap between academic research which seeks to develop assistive technology to access the internet and the translation into real world use of this technology.

    Molecular diagnostics offers quick access to information but fails to operate at a speed required for clinical decision-making. Our novel methodology, droplet-on-thermocouple silhouette real-time polymerase chain reaction (DOTS qPCR), uses interfacial effects for droplet actuation, inhibition relief, and amplification sensing. DOTS qPCR has sample-to-answer times as short as 3 min 30 s. In infective endocarditis diagnosis, DOTS qPCR demonstrates reproducibility, differentiation of antibiotic susceptibility, subpicogram limit of detection, and thermocycling speeds of up to 28 s/cycle in the presence of tissue contaminants. Langmuir and Gibbs adsorption isotherms are used to describe the decreasing interfacial tension upon amplification. Moreover, a log-linear relationship with low threshold cycles is presented for real-time quantification by imaging the droplet-on-thermocouple silhouette with a smartphone. DOTS qPCR resolves several limitations of commercially available real-time PCR systems, which rely on fluorescence detection, have substantially higher threshold cycles, and require expensive optical components and extensive sample preparation. Due to the advantages of low threshold cycle detection, we anticipate extending this technology to biological research applications such as single cell, single nucleus, and single DNA molecule analyses. Our work is the first demonstrated use of interfacial effects for sensing reaction progress, and it will enable point-of-care molecular diagnosis of infections. PMID:26601245

  12. The role of international sustainable development law principles in enabling effective renewable energy policy – a South African perspective.

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available It is universally accepted that renewable energy is an important contributing factor towards the promotion of sustainable development. The implementation of renewable energy needs to be regulated in an effective manner which in turn necessitates the formulation of law and policy geared towards sustainable development. Recent policy developments in South Africa propose to facilitate the promotion of sustainable development through the implementation of renewable energy, among others. In terms of existing energy policy in South-Africa, the interconnectivity of renewable energy and sustainable development is evident. Most notably, the White Paper on Renewable Energy of 2003 promotes increased access to affordable renewable energy in order to contribute to sustainable development. Moreover, the 2008 first review of the National Energy Efficiency Strategy of the Republic of South-Africa of 2005 states that in order for the country’s renewable energy policy to be considered sustainable, it needs to facilitate development in the social, economic and environmental spheres. Notwithstanding, attaining the goal of sustainable development depends on whether all its effecting principles are catered for in the policy developments. Accordingly, in order to ascertain whether South-African law and policy can successfully facilitate/enable sustainable development via the implementation of renewable energy, a specific methodology is proposed. In terms of the New Delhi Declaration of 2002 there are 7 principles of international law effecting sustainable development. These principles will be used as criteria in a principled assessment of South-African renewable energy law and policy in order to establish whether the goal of promoting sustainable development would be effected through the national policy developments.

    Skin is the body's largest organ and is responsible for the transduction of a vast amount of information. This conformable material simultaneously collects signals from external stimuli that translate into information such as pressure, pain, and temperature. The development of an electronic material, inspired by the complexity of this organ is a tremendous, unrealized engineering challenge. However, the advent of carbon-based electronics may offer a potential solution to this long-standing problem. In this Account, we describe the use of an organic field-effect transistor (OFET) architecture to transduce mechanical and chemical stimuli into electrical signals. In developing this mimic of human skin, we thought of the sensory elements of the OFET as analogous to the various layers and constituents of skin. In this fashion, each layer of the OFET can be optimized to carry out a specific recognition function. The separation of multimodal sensing among the components of the OFET may be considered a "divide and conquer" approach, where the electronic skin (e-skin) can take advantage of the optimized chemistry and materials properties of each layer. This design of a novel microstructured gate dielectric has led to unprecedented sensitivity for tactile pressure events. Typically, pressure-sensitive components within electronic configurations have suffered from a lack of sensitivity or long mechanical relaxation times often associated with elastomeric materials. Within our method, these components are directly compatible with OFETs and have achieved the highest reported sensitivity to date. Moreover, the tactile sensors operate on a time scale comparable with human skin, making them ideal candidates for integration as synthetic skin devices. The methodology is compatible with large-scale fabrication and employs simple, commercially available elastomers. The design of materials within the semiconductor layer has led to the incorporation of selectivity and sensitivity within

  17. GeoSpark SQL: An Effective Framework Enabling Spatial Queries on Spark

    Directory of Open Access Journals (Sweden)

    Zhou Huang

    2017-09-01

    Full Text Available In the era of big data, Internet-based geospatial information services such as various LBS apps are deployed everywhere, followed by an increasing number of queries against the massive spatial data. As a result, the traditional relational spatial database (e.g., PostgreSQL with PostGIS and Oracle Spatial cannot adapt well to the needs of large-scale spatial query processing. Spark is an emerging outstanding distributed computing framework in the Hadoop ecosystem. This paper aims to address the increasingly large-scale spatial query-processing requirement in the era of big data, and proposes an effective framework GeoSpark SQL, which enables spatial queries on Spark. On the one hand, GeoSpark SQL provides a convenient SQL interface; on the other hand, GeoSpark SQL achieves both efficient storage management and high-performance parallel computing through integrating Hive and Spark. In this study, the following key issues are discussed and addressed: (1 storage management methods under the GeoSpark SQL framework, (2 the spatial operator implementation approach in the Spark environment, and (3 spatial query optimization methods under Spark. Experimental evaluation is also performed and the results show that GeoSpark SQL is able to achieve real-time query processing. It should be noted that Spark is not a panacea. It is observed that the traditional spatial database PostGIS/PostgreSQL performs better than GeoSpark SQL in some query scenarios, especially for the spatial queries with high selectivity, such as the point query and the window query. In general, GeoSpark SQL performs better when dealing with compute-intensive spatial queries such as the kNN query and the spatial join query.

  18. Cariporide enables hemodynamically more effective chest compression by leftward shift of its flow-depth relationship.

    Science.gov (United States)

    Kolarova, Julieta D; Ayoub, Iyad M; Gazmuri, Raúl J

    2005-06-01

    When given during closed-chest resuscitation, cariporide (4-isopropyl-methylsulfonylbenzoyl-guanidine methanesulfonate; a selective inhibitor of the Na(+)/H(+) exchanger isoform-1) enables generation of viable perfusion pressures with less depth of compression. We hypothesized that this effect results from greater blood flows generated for a given depth of compression. Two series of 14 rats each underwent 10 min of untreated ventricular fibrillation followed by 8 min of chest compression before defibrillation was attempted. Compression depth was adjusted to maintain an aortic diastolic pressure (ADP) between 26 and 28 mmHg in the first series and between 36 and 38 mmHg in the second series. Within each series, rats were randomized to receive cariporide (3 mg/kg) or NaCl (0.9%; control) before chest compression was started. Blood flow was measured using 15-mum fluorescent microspheres. Less depth of compression was required to maintain the target ADP when cariporide was present in both series 1 (13.6 +/- 1.2 vs. 16.6 +/- 1.2 mm; P < 0.001) and series 2 (15.3 +/- 1.0 vs. 18.9 +/- 1.5 mm; P < 0.001). Despite less compression depth, the cardiac index in cariporide-treated rats was comparable to control rats in series 1 (11.1 +/- 0.7 vs. 11.3 +/- 1.4 ml.min(-1).kg(-1); P = not significant) but higher in series 2 (15.5 +/- 2.3 vs. 9.9 +/- 1.4 ml.min(-1).kg(-1); P < 0.05). Increases in compression depth (from series 1 to series 2) increased myocardial, cerebral, and adrenal blood flow in cariporide-treated rats. We conclude that cariporide enhances the efficacy of closed-chest resuscitation by leftward shift of the flow-depth relationship.

  6. Collaboration Between Universities: An effective way of sustaining community-university partnerships?

    Directory of Open Access Journals (Sweden)

    Jonathan Pratt

    2011-11-01

    Full Text Available This article highlights some of the opportunities and challenges that collaboration between higher education institutions (HEIs can bring to the development of sustainable community-university partnerships. In particular, it explores the potential for universities to collaborate on building effective engagement mechanisms (such as helpdesks, ‘hub and spoke’ contact models, and research groups to review ideas for activities that will support an ongoing flow of new projects and partnerships over time. It draws on evidence gathered from the evaluation and coordination of the South East Coastal Communities (SECC program, an almost unique experiment in collaboration between English universities. In an ‘age of austerity’, opportunities to reduce costs without damaging core services are of particular interest to public funding bodies. The article suggests that collaboration between universities may be an efficient and effective way of engaging with local communities, but that it is not cost-free, and high-level strategic buy-in within HEIs is required if community-university partnerships are to thrive in the current higher education funding environment. The article also suggests that there may be a geographic dimension to effective collaboration between universities in both community-university partnership work and the mechanisms that support community engagement. Inter-university collaboration across the whole region covered by the SECC program has been much weaker than collaboration at a subregional level and within ‘city-regions’ in particular. This raises a key question: does the natural geography for effective collaboration between universities need to reflect, at least in part, the geographies of communities themselves, in terms of lived experiences and/or community representation? Such a debate has interesting and timely parallels in the United Kingdom, where the new coalition government is bringing about a fundamental shift in the

  8. The High Degree of Sequence Plasticity of the Arenavirus Noncoding Intergenic Region (IGR) Enables the Use of a Nonviral Universal Synthetic IGR To Attenuate Arenaviruses.

    Science.gov (United States)

    Iwasaki, Masaharu; Cubitt, Beatrice; Sullivan, Brian M; de la Torre, Juan C

    2016-01-06

    Hemorrhagic fever arenaviruses (HFAs) pose important public health problems in regions where they are endemic. Concerns about human-pathogenic arenaviruses are exacerbated because of the lack of FDA-licensed arenavirus vaccines and because current antiarenaviral therapy is limited to an off-label use of ribavirin that is only partially effective. We have recently shown that the noncoding intergenic region (IGR) present in each arenavirus genome segment, the S and L segments (S-IGR and L-IGR, respectively), plays important roles in the control of virus protein expression and that this knowledge could be harnessed for the development of live-attenuated vaccine strains to combat HFAs. In this study, we further investigated the sequence plasticity of the arenavirus IGR. We demonstrate that recombinants of the prototypic arenavirus lymphocytic choriomeningitis virus (rLCMVs), whose S-IGRs were replaced by the S-IGR of Lassa virus (LASV) or an entirely nonviral S-IGR-like sequence (Ssyn), are viable, indicating that the function of S-IGR tolerates a high degree of sequence plasticity. In addition, rLCMVs whose L-IGRs were replaced by Ssyn or S-IGRs of the very distantly related reptarenavirus Golden Gate virus (GGV) were viable and severely attenuated in vivo but able to elicit protective immunity against a lethal challenge with wild-type LCMV. Our findings indicate that replacement of L-IGR by a nonviral Ssyn could serve as a universal molecular determinant of arenavirus attenuation. Hemorrhagic fever arenaviruses (HFAs) cause high rates of morbidity and mortality and pose important public health problems in regions where they are endemic. Implementation of live-attenuated vaccines (LAVs) will represent a major step to combat HFAs. Here we document that the arenavirus noncoding intergenic region (IGR) has a high degree of plasticity compatible with virus viability. This observation led us to generate recombinant LCMVs containing nonviral synthetic IGRs. These r

    Full Text Available We propose an effective anisotropic fluid description for a generic infrared-modified theory of gravity. In our framework, the additional component of the acceleration, commonly attributed to dark matter, is explained as a radial pressure generated by the reaction of the dark energy fluid to the presence of baryonic matter. Using quite general assumptions, and a microscopic description of the fluid in terms of a Bose–Einstein condensate of gravitons, we find the static, spherically symmetric solution for the metric in terms of the Misner–Sharp mass function and the fluid pressure. At galactic scales, we correctly reproduce the leading MOND-like log⁡(r and subleading (1/rlog⁡(r terms in the weak-field expansion of the potential. Our description also predicts a tiny (of order 10−6 for a typical spiral galaxy Machian modification of the Newtonian potential at galactic scales, which is controlled by the cosmological acceleration.

  16. Activating Peripheral Innate Immunity Enables Safe and Effective Oncolytic Virotherapy in the Brain

    Full Text Available The oncolytic mutant vesicular stomatitis virus VSVΔ51 achieves robust efficacy in multiple extracranial tumor models. Yet for malignancies of the brain, direct intratumoral infusion of VSVΔ51 causes lethal virus-induced neuropathology. Here, we have developed a novel therapeutic regime that uses peripheral immunization with a single sub-lethal dose of VSVΔ51 to establish an acute anti-viral state that enables the safe intracranial (IC infusion of an otherwise lethal dose of VSVΔ51 within just 6 hr. Although type I interferons alone appeared insufficient to explain this protective phenotype, serum isolated at early time points from primed animals conferred protection against an IC dose of virus. Adaptive immune populations had minimal contributions. Finally, the therapeutic utility of this novel strategy was demonstrated by peripherally priming and intracranially treating mice bearing aggressive CT2A syngeneic astrocytomas with VSVΔ51. Approximately 25% of animals achieved complete regression of established tumors, with no signs of virus-induced neurological impairment. This approach may harness an early warning system in the brain that has evolved to protect the host against otherwise lethal neurotropic viral infections. We have exploited this protective mechanism to safely and efficaciously treat brain tumors with an otherwise neurotoxic virus, potentially widening the available treatment options for oncolytic virotherapy in the brain.

    2016-01-01

    There is a current drive towards enabling the deployment of increasingly autonomous systems in the National Airspace System (NAS). However, shifting the traditional roles and responsibilities between humans and automation for safety critical tasks must be managed carefully, otherwise the current emergent safety properties of the NAS may be disrupted. In this paper, a verification activity to assess the emergent safety properties of a clearly defined, safety critical, operational scenario that possesses tasks that can be fluidly allocated between human and automated agents is conducted. Task allocation role sets were proposed for a human-automation team performing a contingency maneuver in a reduced crew context. A safety critical contingency procedure (engine out on takeoff) was modeled in the Soar cognitive architecture, then translated into the Hybrid Input Output formalism. Verification activities were then performed to determine whether or not the safety properties held over the increasingly autonomous system. The verification activities lead to the development of several key insights regarding the implicit assumptions on agent capability. It subsequently illustrated the usefulness of task annotations associated with specialized requirements (e.g., communication, timing etc.), and demonstrated the feasibility of this approach.

    Metagenomics is the study of the microbial genomes isolated from communities found on our bodies or in our environment. By correctly determining the relation between human health and the human associated microbial communities, novel mechanisms of health and disease can be found, thus enabling the development of novel diagnostics and therapeutics. Due to the diversity of the microbial communities, strategies developed for aligning human genomes cannot be utilized, and genomes of the microbial species in the community must be assembled de novo. However, in order to obtain the best metagenomic assemblies, it is important to choose the proper assembler. Due to the rapidly evolving nature of metagenomics, new assemblers are constantly created, and the field has not yet agreed on a standardized process. Furthermore, the truth sets used to compare these methods are either too simple (computationally derived diverse communities) or complex (microbial communities of unknown composition), yielding results that are hard to interpret. In this analysis, we interrogate the strengths and weaknesses of five popular assemblers through the use of defined biological samples of known genomic composition and abundance. We assessed the performance of each assembler on their ability to reassemble genomes, call taxonomic abundances, and recreate open reading frames (ORFs). We tested five metagenomic assemblers: Omega, metaSPAdes, IDBA-UD, metaVelvet and MEGAHIT on known and synthetic metagenomic data sets. MetaSPAdes excelled in diverse sets, IDBA-UD performed well all around, metaVelvet had high accuracy in high abundance organisms, and MEGAHIT was able to accurately differentiate similar organisms within a community. At the ORF level, metaSPAdes and MEGAHIT had the least number of missing ORFs within diverse and similar communities respectively. Depending on the metagenomics question asked, the correct assembler for the task at hand will differ. It is important to choose the appropriate

    The global construction sector is experiencing major improvements to building materials used in large quantities through commercial applications of nanotechnology. Nano-enabled construction products hold great promise for energy efficiency and resource conservation, but risk assessments lag as new products emerge. This paper presents results from an inventory, survey, and exposure assessment conducted by the authors and explores these findings in the broader context of evolving research trends and responsible development of nanotechnology. An inventory of 458 reportedly nano-enabled construction products provided insight into product availability, potential exposures, and deficiencies in risk communication that are barriers to adoption of proactive safety measures. Seasoned construction trainers surveyed were largely unaware of the availability of nano-enabled construction products. Exposure assessment demonstrated the effectiveness of ventilation to reduce exposures during mechanical abrasion of photocatalytic tiles containing titanium dioxide (TiO2). Dissociated particles of TiO2 just above the nanoscale (138 nm) were detected in the debris collected during cutting of the tiles, but measurements were below recommended exposure limits for TiO2. Exposure assessments remain scarce, and toxicological understanding primarily pertains to unincorporated nanomaterials; less is known about the occupational risks of nano-enabled construction products across their life cycle. Further research is needed to characterize and quantify exposure to debris released from nanocomposite materials for realistic risk assessment, and to ascertain how nanocomposite matrices, fillers, and degradation forces interact to affect release dynamics. Improving risk communication strategies and implementing safe work practices will cultivate responsible development of nanotechnology in construction, as will multidisciplinary research efforts.

    Full Text Available We study the modified Friedmann equation in the Friedmann-Robertson-Walker universe with quantum effect. Our modified results mainly stem from the new entropy-area relation and the novel idea of Padmanabhan, who considers the cosmic space to be emerging as the cosmic time progresses, so that the expansion rate of the universe is determined by the difference of degrees of freedom between the holographic surface and the bulk inside. We also discuss the possibility of having bounce cosmological solution from the modified Friedmann equation in spatially flat geometry.

  18. Developing a mobile application to better inform patients and enable effective consultation in implant dentistry

    Directory of Open Access Journals (Sweden)

    Erokan Canbazoglu

    2016-01-01

    Full Text Available The field of dentistry lacks satisfactory tools to help visualize planned procedures and their potential results to patients. Dentists struggle to provide an effective image in their patient's mind of the end results of the planned treatment only through verbal explanations. Thus, verbal explanations alone often cannot adequately help the patients make a treatment decision. Inadequate attempts are frequently made by dentists to sketch the procedure for the patient in an effort to depict the treatment. These attempts however require an artistic ability not all dentists have. Real case photographs are sometimes of help in explaining and illustrating treatments. However, particularly in implant cases, real case photographs are often ineffective and inadequate. The purpose of this study is to develop a mobile application with an effective user interface design to support the dentist–patient interaction by providing the patient with illustrative descriptions of the procedures and the end result. Sketching, paper prototyping, and wire framing were carried out with the actual user's participation. Hard and soft dental tissues were modeled using three dimensional (3D modeling programs and real cases. The application enhances the presentation to the patients of potential implants and implant supported prosthetic treatments with rich 3D illustrative content. The application was evaluated in terms of perceived ease of use and perceived usefulness through an online survey. The application helps improve the information sharing behavior of dentists to enhance the patients' right to make informed decisions. The paper clearly demonstrates the relevance of interactive communication technologies for dentist–patient communication.

  20. Comparative Effectiveness Research, Genomics-Enabled Personalized Medicine, and Rapid Learning Health Care: A Common Bond

    Ginsburg, Geoffrey S.; Kuderer, Nicole M.

    2012-01-01

    Despite stunning advances in our understanding of the genetics and the molecular basis for cancer, many patients with cancer are not yet receiving therapy tailored specifically to their tumor biology. The translation of these advances into clinical practice has been hindered, in part, by the lack of evidence for biomarkers supporting the personalized medicine approach. Most stakeholders agree that the translation of biomarkers into clinical care requires evidence of clinical utility. The highest level of evidence comes from randomized controlled clinical trials (RCTs). However, in many instances, there may be no RCTs that are feasible for assessing the clinical utility of potentially valuable genomic biomarkers. In the absence of RCTs, evidence generation will require well-designed cohort studies for comparative effectiveness research (CER) that link detailed clinical information to tumor biology and genomic data. CER also uses systematic reviews, evidence-quality appraisal, and health outcomes research to provide a methodologic framework for assessing biologic patient subgroups. Rapid learning health care (RLHC) is a model in which diverse data are made available, ideally in a robust and real-time fashion, potentially facilitating CER and personalized medicine. Nonetheless, to realize the full potential of personalized care using RLHC requires advances in CER and biostatistics methodology and the development of interoperable informatics systems, which has been recognized by the National Cancer Institute's program for CER and personalized medicine. The integration of CER methodology and genomics linked to RLHC should enhance, expedite, and expand the evidence generation required for fully realizing personalized cancer care. PMID:23071236

    The extinct ocean-going plesiosaurs were unique within vertebrates because they used two flipper pairs identical in morphology for propulsion. Although fossils of these Mesozoic marine reptiles have been known for more than two centuries, the function and dynamics of their tandem-flipper propulsion system has always been unclear and controversial. We address this question quantitatively for the first time in this study, reporting a series of precisely controlled water tank experiments that use reconstructed plesiosaur flippers scaled from well-preserved fossils. Our aim was to determine which limb movements would have resulted in the most efficient and effective propulsion. We show that plesiosaur hind flippers generated up to 60% more thrust and 40% higher efficiency when operating in harmony with their forward counterparts, when compared with operating alone, and the spacing and relative motion between the flippers was critical in governing these increases. The results of our analyses show that this phenomenon was probably present across the whole range of plesiosaur flipper motion and resolves the centuries-old debate about the propulsion style of these marine reptiles, as well as indicating why they retained two pairs of flippers for more than 100 million years. © 2017 The Author(s).

    2017-08-01

    Full Text Available Despite many advances in the area of wind effects on structures in recent decades, research has been traditionally conducted within limited resources scattered geographically. With the trend toward increasingly complex designs of civil infrastructure combined with the escalating potential for losses by extreme wind events, a new culture of research needs to be established based on innovative and collaborative solutions for better management of the impact of extreme wind events. To address this change, this paper presents a new paradigm of a multiscale cyber-based laboratory framework for the analysis/design, modeling, and simulation of wind load effects based on an ongoing collaborative cyberinfrastructure-based platform, Virtual Organization for Reducing the Toll of EXtreme Winds (VORTEX-Winds, https://vortex-winds.org, and discusses its current status since its inception in 2007 and ongoing developments. This collaborative framework as it evolves would enable a paradigm shift by offering advanced cyber-enabled modules (e-modules for accelerating advances in research and education to achieve improved understanding and better modeling of wind effects on structures. Accordingly, it will enhance wind community’s analysis and design capabilities to address next-generation challenges posed by wind. Through empowering those without computational or experimental resources, the e-modules will encompass a large set of subject areas and topics categorized as Database-enabled design, Full-scale/Field site data repository, Statistical/Stochastic toolboxes, Tele-experimentation, Uncertainty modeling, Damage assessment, and Computational platforms. This prototype will allow access to the individual e-module, while it is envisaged that next level of development in VORTEX-Winds will have the capability for an automated and integrated analysis/design through a nexus of e-modules. A highlight of the e-modules currently completed or in development is presented

    University lecturers often complain about their students’ lack of learning strategies, but not many universities in Spain offer specific courses in this area. Studies on their effectiveness are also rare. This study presents the results of a Learning Strategies Course implemented at the School of Teacher Training and Education, University of Oviedo, Spain. A quasi-experimental design was used with an experi-mental (n = 60) and a control group (n = 57) of students on the Educational Psychology course. A Spanish adaptation of the Motivated Strategies for Learning Questionnaire (MSLQ): the CEAMR2 was used as a pre and post-test measure. Group A (EG) received training in learning strategies, while group B (CG) received no training. Post-test measures showed significant differences in five out of the ten learning strategies assessed: elaboration, organization, repetition, self-questioning and study space, and also an improvement in one out of the six motivational scales: control of learning beliefs. The results suggest that learning strategies courses with proven effectiveness should be offered to university students.

    The Medium-Resolution Survey Spectrometer (MRSS) is a multi-purpose wideband spectrograph being designed for the Origins Space Telescope (OST -- the NASA-funded far-IR flagship mission study being prepared for the 2020 Decadal Survey). The sensitivity possible with the combination of the actively-cooled OST telescope and new-generation far-IR direct detector arrays is outstanding; potentially offering a 10,000x improvement in speed over the Herschel, SOFIA for point-source measurements, and factor of more than 1,000,000 for spatial-spectral mapping. Massive galaxy detection rates are possible via the rest-frame mid- and far-IR spectral features, overcoming continuum confusion and reaching back to the epoch of reionization. The MRSS covers the full 30 to 670 micron band instantaneously at a resolving power (R) of 500 using 6 logarithmically-spaced grating modules. Each module couples at least 60 and up to 200 spatial beams simultaneously, enabling true 3-D spectral mapping, both for the blind extragalactic surveys and for mapping all phases of interstellar matter in the Milky Way and nearby galaxies. Furthermore, a high-resolution mode inserts a long-path Fourier-transform interferometer into the light path in advance of the grating backends, enabling R up to 38,000 x [100 microns / lambda], while preserving the basic grating sensitivity for line detection.Maximum scientific return with the MRSS on OST will require large arrays of direct detectors with sensitivity meeting or exceeding the photon background limit due to zodiacal and Galactic dust: NEP~3e-20 W/sqrt(Hz). The total pixel count for all 6 bands is ~200,000 pixels. These sensitive far-IR detector arrays are not provided by the kind of industrial efforts producing the the optical and near-IR detectors, but they are being developed by NASA scientists, including OST team members. We outline the rapid progress in this area, briefly highlighting a) recent low-NEP single-pixel measurements which meet the

    The purpose of this study was to determine the effectiveness of an educational program based on the Belief, Attitude, Subjective Norm, and Enabling Factors (BASNEF) Model on the nutritional behavior among second-grade, middle school, female students in Isfahan city. This quasi-experimental study was performed on 72 students. The samples were randomly divided in two groups (36 in the intervention group and 36 in the control group). The data collection tools were validated and had reliable questionnaires. For the intervention group, a 75-minute educational session was held thrice. The control group had no education. The BASNEF model constructs guided the development of the questionnaires and content of the educational sessions. The independent t-test and paired t-test were used to analyze the data. A two-tailed P value lower than 0.05 was considered to be statistically significant. According to the results, the mean scores of knowledge and model variables (Belief, Attitude, Subjective Norm, and Enabling Factors) had a significant difference in the two groups after intervention (P educational intervention, 36.1% of the students had unfavorable nutritional behavior. In the control group, 88.9% of the students had unfavorable nutritional behavior, before and one month after intervention. The present study showed that nutrition education intervention based on the BASNEF model could promote the nutritional behavior in girl students.

    Full Text Available The paper analyzes the effects that occur in the process of the educational environment informatization. The following effects were analyzed: information richness, openness, individualization of learning and collaboration. Examples of educational practice, illustrating the significant changes of the university educational environment associated with the manifestation of these effects, are presented. The aim of the pilot study carried out in Herzen University was to identify the attitude to the listed effects of teachers and students who are using information and communication technology in the educational interactions. The leading method of study were a series of surveys addressed to teachers and students. Groups of questions were related to basic information effects, manifested in the educational environment of the university. The total number of the survey participants is 200 students (bachelors and masters and 100 teachers, most actively using electronic environment for research, education and professional activities. Qualitative and quantitative analysis of the results showed that information richness, spatial and temporal freedom of educational interactions are demanded by students, but at the same time, the data indicated a lack of systematic pedagogical support for the information and educational activities of students. A large part of students show a high autonomy in the information educational environment, but also demands implementing individualized information and communication educational request. Students and teachers are actively using a variety of information and communication opportunities of the electronic environment, but students’ activeness in the electronic environment is largely determined by the recommendations of teachers, rather than by a free choice of educational opportunities. The participants of the educational environment acquire a significant degree of freedom in relation to the time and place of interaction with

    Full Text Available We explore the effective degrees of freedom in the early Universe, from before the electroweak scale at a few femtoseconds after the Big Bang until the last positrons disappeared a few minutes later. We look at the established concepts of effective degrees of freedom for energy density, pressure, and entropy density, and introduce effective degrees of freedom for number density as well. We discuss what happens with particle species as their temperature cools down from relativistic to semi- and non-relativistic temperatures, and then annihilates completely. This will affect the pressure and the entropy per particle. We also look at the transition from a quark-gluon plasma to a hadron gas. Using a list a known hadrons, we use a “cross-over” temperature of 214 MeV, where the effective degrees of freedom for a quark-gluon plasma equals that of a hadron gas.

    (1) To investigate the contribution of job characteristics and personal characteristics to the explanation of health effects among university personnel; (2) to investigate the differences between scientific personnel (SP) and non-scientific personnel (NSP); (3) to investigate whether health effects occurred one after another. The well being at work of employees at a Dutch university (n=2,522) was investigated by means of a questionnaire. A model was constructed in which several job and personal characteristics were set out against health effects. The latter were assumed to occur in phases: decreased "job satisfaction" as an early effect, followed by increased "tension" and "emotional exhaustion", and possibly also by increased "perceived health complaints". The contribution of job and personal characteristics to the explanation of health effects was investigated by means of linear regression analysis, with separate analyses for SP and NSP. Positive job characteristics, especially professional expertise and work variety, contributed to the explanation of "job satisfaction". The major contributors to "tension" and "emotional exhaustion" were negative characteristics, such as work pressure. Besides the negative aspects, the major contributors to the explanation of "perceived health complaints" were sex, age and other health effects. In NSP, social support contributed to the explanation of "tension" and "emotional exhaustion", but not in SP. The explained variance of "job satisfaction" by the positive job characteristics in NSP was much higher than that in SP. To investigate whether health effects occurred one after another, we considered explained variance. Explained variance in "job satisfaction" was much higher than in "perceived health complaints". "Emotional exhaustion" and "tension" were in between. Contrary to expectations, decision latitude and social support played only minor roles. Also, the differences between SP and NSP were smaller than expected. As

    The self-biasing effects of ion gel from source and drain electrodes on electrical characteristics of single layer and few layer molybdenum disulfide (MoS 2 ) field-effect transistor (FET) have been studied. The self-biasing effect of ion gel is tested for two different configurations, covered and open, where ion gel is in contact with either one or both, source and drain electrodes, respectively. In open configuration, the linear output characteristics of the pristine device becomes nonlinear and on-off ratio drops by 3 orders of magnitude due to the increase in "off" current for both single and few layer MoS 2 FETs. However, the covered configuration results in a highly asymmetric output characteristics with a rectification of around 10 3 and an ideality factor of 1.9. This diode like behavior has been attributed to the reduction of Schottky barrier width by the electric field of self-biased ion gel, which enables an efficient injection of electrons by tunneling at metal-MoS 2 interface. Finally, finite element method based simulations are carried out and the simulated results matches well in principle with the experimental analysis. These self-biased diodes can perform a crucial role in the development of high-frequency optoelectronic and valleytronic devices.

    Variations in terrestrial oxygen-isotope reconstructions from ice cores and speleothems have been primarily attributed to climatic changes of surface air temperature, precipitation amount, or atmospheric circulation. Here we demonstrate with the fully coupled isotope-enabled Community Earth System Model an additional process contributing to the oxygen-isotope variations during glacial meltwater events. This process, termed "the direct meltwater effect," involves propagating large amounts of isotopically depleted meltwater throughout the hydrological cycle and is independent of climatic changes. We find that the direct meltwater effect can make up 15-35% of the δ18O signals in precipitation over Greenland and eastern Brazil for large freshwater forcings (0.25-0.50 sverdrup (106 m3/s)). Model simulations further demonstrate that the direct meltwater effect increases with the magnitude and duration of the freshwater forcing and is sensitive to both the location and shape of the meltwater. These new modeling results have important implications for past climate interpretations of δ18O.

  14. Maximizing Power Output in Homogeneous Charge Compression Ignition (HCCI) Engines and Enabling Effective Control of Combustion Timing

    Science.gov (United States)

    Saxena, Samveg

    Homogeneous Charge Compression Ignition (HCCI) engines are one of the most promising engine technologies for the future of energy conversion from clean, efficient combustion. HCCI engines allow high efficiency and lower CO2 emission through the use of high compression ratios and the removal of intake throttle valves (like Diesel), and allow very low levels of urban pollutants like nitric oxide and soot (like Otto). These engines, however, are not without their challenges, such as low power density compared with other engine technologies, and a difficulty in controlling combustion timing. This dissertation first addresses the power output limits. The particular strategies for enabling high power output investigated in this dissertation focus on avoiding five critical limits that either damage an engine, drastically reduce efficiency, or drastically increase emissions: (1) ringing limits, (2) peak in-cylinder pressure limits, (3) misfire limits, (4) low intake temperature limits, and (5) excessive emissions limits. The research shows that the key factors that enable high power output, sufficient for passenger vehicles, while simultaneously avoiding the five limits defined above are the use of: (1) high intake air pressures allowing improved power output, (2) highly delayed combustion timing to avoid ringing limits, and (3) using the highest possible equivalence ratio before encountering ringing limits. These results are revealed by conducting extensive experiments spanning a wide range of operating conditions on a multi-cylinder HCCI engine. Second, this dissertation discusses strategies for effectively sensing combustion characteristics on a HCCI engine. For effective feedback control of HCCI combustion timing, a sensor is required to quantify when combustion occurs. Many laboratory engines use in-cylinder pressure sensors but these sensors are currently prohibitively expensive for wide-scale commercialization. Instead, ion sensors made from inexpensive sparkplugs

    There is substantial evidence for the efficacy and effectiveness of targeted parenting programmes but much less evidence regarding universal parenting programmes. The aim of the present study was to evaluate the effectiveness of the CANparent Trial of 12 universal parenting programmes, which were made available to parents of all children aged 0-6 years in three local authorities in England. To the best of our knowledge, this is the first study of universal parenting programmes on this scale. Parents accessed a voucher, value £100, to attend an accredited programme of parenting classes. Parents completed measures of their mental well-being, parenting efficacy, parenting satisfaction, and parenting stress, at pre- and post-course. Comparative data were derived from a sample of non-participant parents in 16 local authorities not providing CANparent programmes. A quasi-experimental design was adopted following estimation of propensity scores to balance the two groups on socio-demographic variables. Following their programme, changes in parenting stress were small and nonsignificant (Cohen's d frequency 0.07; intensity, 0.17). Participating parents showed significantly greater improvements than the comparison group for parenting efficacy (0.89) but not parenting satisfaction (-0.01). Mental well-being improved from 0.29 SD below the national norm to the national norm after the course. Parents were overwhelmingly positive about their course (88-94%) but this was lower for improvement in their relationship with their child (74%) and being a better parent (76%). The CANparent Trial demonstrated that universal parenting programmes can be effective in improving parents' sense of parenting efficacy and mental well-being when delivered to the full range of parents in community settings. However, there was no evidence of a reduction in levels of parenting stress; nor was there a significant improvement in satisfaction with being a parent. This is the first study of its kind

    2014-09-01

    Full Text Available A major challenge in monitoring universal health coverage (UHC is identifying an indicator that can adequately capture the multiple components underlying the UHC initiative. Effective coverage, which unites individual and intervention characteristics into a single metric, offers a direct and flexible means to measure health system performance at different levels. We view effective coverage as a relevant and actionable metric for tracking progress towards achieving UHC. In this paper, we review the concept of effective coverage and delineate the three components of the metric - need, use, and quality - using several examples. Further, we explain how the metric can be used for monitoring interventions at both local and global levels. We also discuss the ways that current health information systems can support generating estimates of effective coverage. We conclude by recognizing some of the challenges associated with producing estimates of effective coverage. Despite these challenges, effective coverage is a powerful metric that can provide a more nuanced understanding of whether, and how well, a health system is delivering services to its populations.

    Principal component analysis was applied to effectively optimize the operational conditions of a fluidized bed granulator for preparing granules with excellent compaction and tablet physical properties. The crucial variables that affect the properties of the granules, their compactability and the resulting tablet properties were determined through analysis of a series of granulation and tabletting experiments. Granulation was performed while the flow rate and concentration of the binder were changed as independent operational variables, according to a two-factor central composite design. Thirteen physicochemical properties of granules and tablets were examined: powder properties (particle size, size distribution width, Carr's index, Hausner ratio and aspect ratio), compactability properties (pressure transmission ratio, die wall force and ejection force) and tablet properties (tensile strength, friability, disintegration time, weight variation and drug content uniformity). Principal component analysis showed that the pressure transmission ratio, die wall force and Carr's index were the most important variables in granule preparation. Multiple regression analysis also confirmed these results. Furthermore, optimized operational conditions obtained from the multiple regression analysis enabled the production of granules with desirable properties for tabletting. This study presents the first use of principle component analysis for identifying and successfully predicting the most important variables in the process of granulation and tabletting.

    Full Text Available Abstract Background Hearing impairment at the workplace, and the resulting psychosocial problems are a major health problem with substantial costs for employees, companies, and society. Therefore, it is important to develop interventions to support hearing impaired employees. The objective of this article is to describe the design of a randomized controlled trial evaluating the (cost- effectiveness of a Vocational Enablement Protocol (VEP compared with usual care. Methods/Design Participants will be selected with the 'Hearing and Distress Screener'. The study population will consist of 160 hearing impaired employees. The VEP intervention group will be compared with usual care. The VEP integrated care programme consists of a multidisciplinary assessment of auditory function, work demands, and personal characteristics. The goal of the intervention is to facilitate participation in work. The primary outcome measure of the study is 'need for recovery after work'. Secondary outcome measures are coping with hearing impairment, distress, self-efficacy, psychosocial workload, job control, general health status, sick leave, work productivity, and health care use. Outcome measures will be assessed by questionnaires at baseline, and 3, 6, 9, and 12 months after baseline. The economic evaluation will be performed from both a societal and a company perspective. A process evaluation will also be performed. Discussion Interventions addressing occupational difficulties of hearing impaired employees are rare but highly needed. If the VEP integrated care programme proves to be (cost- effective, the intervention can have an impact on the well-being of hearing impaired employees, and thereby, on the costs for the company as well for the society.

    Modern advances in neurotechnology rely on effectively harnessing physical tools and insights towards remote neural control, thereby creating major new scientific and therapeutic opportunities. Specifically, rapid temperature pulses were shown to increase membrane capacitance, causing capacitive currents that explain neural excitation, but the underlying biophysics is not well understood. Here, we show that an intramembrane thermal-mechanical effect wherein the phospholipid bilayer undergoes axial narrowing and lateral expansion accurately predicts a potentially universal thermal capacitance increase rate of ˜0.3 % /°C . This capacitance increase and concurrent changes in the surface charge related fields lead to predictable exciting ionic displacement currents. The new MechanoElectrical Thermal Activation theory's predictions provide an excellent agreement with multiple experimental results and indirect estimates of latent biophysical quantities. Our results further highlight the role of electro-mechanics in neural excitation; they may also help illuminate subthreshold and novel physical cellular effects, and could potentially lead to advanced new methods for neural control.

    In October, 2015, China's one-child policy was replaced by a universal two-child policy. The effects of the new policy are inevitably speculative, but predictions can be made based on recent trends. The population increase will be relatively small, peaking at 1·45 billion in 2029 (compared with a peak of 1·4 billion in 2023 if the one-child policy continued). The new policy will allow almost all Chinese people to have their preferred number of children. The benefits of the new policy include: a large reduction in abortions of unapproved pregnancies, virtual elimination of the problem of unregistered children, and a more normal sex ratio. All of these effects should improve health outcomes. Effects of the new policy on the shrinking workforce and rapid population ageing will not be evident for two decades. In the meantime, more sound policy actions are needed to meet the social, health, and care needs of the elderly population. Copyright © 2016 Elsevier Ltd. All rights reserved.

Objective of study was to evaluate the effect of Facebook on the social life, health and behavior of medical students. It was a cross sectional, observational and questionnaire based study conducted in Dow University OF Health Sciences during the period of January 2012 to November 2012. We attempted to interview all the participants who could be approached during the period of the study. Participants were MBBS students, while all students of other courses and programs were taken as exclusion criteria. Approximately 1050 questionnaires were distributed to participants. Fifty questionnaires were rejected due to incomplete answers, yielding 1000 usable responses for an approximate 95% response rate. Informed verbal consent was taken from each participant. Study was ethically approved by Institutional Review Board of Dow University of Health Sciences. All the data was entered and analyzed through SPSS 19. Out of total 1000 participants, males were 400 (40%) and females were 600 (60%). Participants were in the age group of 18-25 years with a mean age of 20.08 years. Most of the participants were using Facebook daily (N = 640, 64%) for around 3-4 hours (N = 401, 40.1%). Majority of them (N = 359, 35.9%) believed that they were equally active on Facebook and in real life while few believed their social life became worse after start using Facebook (N = 372, 37.2%). Most of the participants admitted that they were considered as shy in real world (N = 390, 39.0%) while in the world of Facebook they were considered as fun loving by their friends (N = 603, 60.3%). A large number of participants (N = 715, 75%) complained of mood swings.

    Full Text Available Background: Proprioceptive deficiency followed by lateral ankle sprain leads to poor balance is not uncommon. It has been linked with increased injury risk among young athletes. Introducing neuromuscular training programs for this have been believed as one of the means of injury prevention. Hence, this study was aimed to determine the effects of six weeks progressive neuromuscular training (PNM Training on static balance gains among the young athletes with a previous history of ankle sprains. Methods: This study was an experimental study design, with pre and post test method to determine the effects of PNM Training on static balance gains. All data were collected at university’s sports rehabilitation lab before and after six weeks of intervention period. There were 20 male and female volunteer young athletes (20.9 ± 0.85 years of age with a previous history of ankle sprain involving various sports were recruited from the University community. All the subjects were participated in a six week PNM Training that included stability, strength and power training. Outcome measures were collected by calculating the errors on balance error scoring system made by the athletes on static balance before and after the six weeks of intervention period. Static balance was tested in firm and foam surfaces and recorded accordingly. Results: The researchers found a significant decrease (2.40 ± 0.82 in total errors among the samples at the post test compared with their pre test (P >0.05. Conclusions: The study demonstrates that a PNM Training can improve the static balance on both the firm and foam surfaces among the young athletes with a previous history of ankle sprains.

  13. Universal and non universal new physics effects in a general four-fermion process a Z-peak subtracted approach

    CERN Document Server

    Renard, F M

    1996-01-01

    We calculate, using a Z-peak subtracted representation of four-fermion processes previously illustrated for the case of electron-positron annihilation into charged lepton-antilepton, the corresponding expressions of the new physics contributions for the case of final quark-antiquark states, allowing the possibility of both universal and non universal effects. Some examples of models of the first and of the second type are considered for several c.m. energy values, showing that remarkable simplifications are often introduced by our approach. In particular, for the case of a dimension-six lagrangian with anomalous gauge couplings, the same reduced number of parameters that would affect the observables of final leptonic states are essentially retained when one moves to final hadronic states. This leads to great simplifications in the elaboration of constraints and, as a gratifying byproduct, to the possibility of making the signal from these models clearly distinguishable from those from other (both universal an...

  14. Enabling distributed petascale science

    2007-01-01

    Petascale science is an end-to-end endeavour, involving not only the creation of massive datasets at supercomputers or experimental facilities, but the subsequent analysis of that data by a user community that may be distributed across many laboratories and universities. The new SciDAC Center for Enabling Distributed Petascale Science (CEDPS) is developing tools to support this end-to-end process. These tools include data placement services for the reliable, high-performance, secure, and policy-driven placement of data within a distributed science environment; tools and techniques for the construction, operation, and provisioning of scalable science services; and tools for the detection and diagnosis of failures in end-to-end data placement and distributed application hosting configurations. In each area, we build on a strong base of existing technology and have made useful progress in the first year of the project. For example, we have recently achieved order-of-magnitude improvements in transfer times (for lots of small files) and implemented asynchronous data staging capabilities; demonstrated dynamic deployment of complex application stacks for the STAR experiment; and designed and deployed end-to-end troubleshooting services. We look forward to working with SciDAC application and technology projects to realize the promise of petascale science

    Achieving universal health coverage (UHC) involves distributing resources, especially human resources for health (HRH), to match population needs. This paper explores the policy lessons on HRH from four countries that have achieved sustained improvements in UHC: Brazil, Ghana, Mexico and Thailand. Its purpose is to inform global policy and financial commitments on HRH in support of UHC. The paper reports on country experiences using an analytical framework that examines effective coverage in relation to the availability, accessibility, acceptability and quality (AAAQ) of HRH. The AAAQ dimensions make it possible to perform tracing analysis on HRH policy actions since 1990 in the four countries of interest in relation to national trends in workforce numbers and population mortality rates. The findings inform key principles for evidence-based decision-making on HRH in support of UHC. First, HRH are critical to the expansion of health service coverage and the package of benefits; second, HRH strategies in each of the AAAQ dimensions collectively support achievements in effective coverage; and third, success is achieved through partnerships involving health and non-health actors. Facing the unprecedented health and development challenges that affect all countries and transforming HRH evidence into policy and practice must be at the heart of UHC and the post-2015 development agenda. It is a political imperative requiring national commitment and leadership to maximize the impact of available financial and human resources, and improve healthy life expectancy, with the recognition that improvements in health care are enabled by a health workforce that is fit for purpose.

    Universities contribute significantly to the development of human capital and socio-economic improvement of a country. Due to that, Malaysian universities carried out various initiatives to improve their performance. Most studies have used the Data Envelopment Analysis (DEA) model to measure efficiency rather than effectiveness, even though, the measurement of effectiveness is important to realize how effective a university in achieving its ultimate goals. A university system has two major functions, namely teaching and research and every function has different resources based on its emphasis. Therefore, a university is actually structured as a parallel production system with its overall effectiveness is the aggregated effectiveness of teaching and research. Hence, this paper is proposing a parallel network DEA model to measure the effectiveness of a university. This model includes internal operations of both teaching and research functions into account in computing the effectiveness of a university system. In literature, the graduate and the number of program offered are defined as the outputs, then, the employed graduates and the numbers of programs accredited from professional bodies are considered as the outcomes for measuring the teaching effectiveness. Amount of grants is regarded as the output of research, while the different quality of publications considered as the outcomes of research. A system is considered effective if only all functions are effective. This model has been tested using a hypothetical set of data consisting of 14 faculties at a public university in Malaysia. The results show that none of the faculties is relatively effective for the overall performance. Three faculties are effective in teaching and two faculties are effective in research. The potential applications of the parallel network DEA model allow the top management of a university to identify weaknesses in any functions in their universities and take rational steps for improvement.

    Full Text Available Universal inferences like (i have been taken as evidence for a local/syntactic treatment of scalar implicatures (i.e. theories where the enrichment of "some" into "some but not all" can happen sub-sententially: (i Everybody read some of the books --> Everybody read [some but not all the books]. In this paper, I provide experimental evidence which casts doubt on this argument. The counter-argument relies on a new set of data involving free choice inferences (a sub-species of scalar implicatures and negative counterparts of (i, namely sentences with the quantifier "no" instead of "every". The results show that the globalist account of scalar implicatures is incomplete (mainly because of free choice inferences but that the distribution of universal inferences made available by the localist move remains incomplete as well (mainly because of the negative cases. doi:10.3765/sp.2.2 BibTeX info

    Information about the profile of ballast water discharges in a port is one of the basic elements of the decision making process in ballast water risk assessment and management, and supports the evaluation of dimensions and processes of aquatic species invasions with vessels ballast water. In the lack of ballast water reporting, ballast water discharge assessments need to be conducted. In this study we have assessed and compared ballast water discharge profiles of two ports with different maritime traffic and cargo profiles, the Port of Hamburg (Germany) and the Muuga Harbour, Port of Tallinn (Estonia). This study shows methods and approaches which can be used to assess volumes and donor ports of ballast water discharges for a port at the level of each vessel call. These methods and approaches can be applied to any port to support the implementation of feasible and efficient ballast water management measures and to enable environmental studies including long-term accumulation risks of disinfection by-products from ballast water management systems making use of active substances, as well as for discharges of other chemical compounds.

    Aims: the main objective was to verify if there is a difference on psychopathological symptoms between two groups questioned by two different examiners, controlling for the potential role of social desirability, and other potential covariates. Additionally, we want to assess the level of psychopathology and its socio-demographic correlates.Methods: 185 Coimbra's university students completed the Brief Symptom Inventory/BSI and the Marlowe-Crowne Social Desirability Scale. In one group the examiner was of the same age and academic status as the students, while in the other group the examiner was older and a teacher. We studied the psychopathological correlates with Pearson, point-biserial correlations, and qui-square analyses, and we controlled the potential role of covariates through Quade non-parametric ANCOVAs. Results: The level of distress was lower in comparison with other investigations. Women had higher level of distress and more symptoms of somatization, anxiety, phobic anxiety, obsessive-compulsion, and depression. The students that live a higher distance from home had more anxiety and obsessive-compulsive symptoms. The group assessed by the younger examiner scored higher in distress and in some BSI factors, and had lower levels on social desirability. Conclusions: Sex and distance from home seem important factors for university students' mental health. However, the examiner does have an influence in the evaluation, probably because of social desirability, suggesting that the examiner's characteristics should be given in investigations involving university students.

    Investigate patient perspectives on barriers and enablers to the use and effectiveness of de-escalation techniques for aggression in mental health settings. De-escalation techniques are the recommended first-line intervention for the management of aggression in mental health settings internationally, yet use of higher risk restrictive practices persists. This indicates de-escalation techniques are not used at optimum frequency and/or there are important factors limiting their use and effect. Descriptive qualitative research using semi-structured interviews and Framework Analysis. Inpatient interviews (N = 26) exploring staff, patient and environmental factors influencing the use and effectiveness of staff de-escalation were conducted mid-2014. Three service user researchers led analysis. Data were synthesized in three deductive themes relating to staff, patient and environmental influences on the use and effectiveness of de-escalation techniques. The dominant view was that restrictive practices, rather than de-escalation techniques, are used in response to escalating patient behaviour. Under-use of de-escalation techniques was attributed to: lack of staff reflection on culture and practice and a need to retain control/dominance over patients. Ward rules, patient factors and a lack of staff respect for patients diluted their effectiveness. Participants identified a systematic process of de-escalation, rule subversion, reduced social distance and staff authenticity as enablers of effective de-escalation. This study investigated patient perspectives on staff, patient and environmental influences on the use and effectiveness of de-escalation techniques. Our framework of barriers and enablers provides indicators of organizational/behaviour change targets for interventions seeking to reduce violence and restrictive practices through enhanced de-escalation techniques. © 2017 John Wiley & Sons Ltd.

    Combinatorial phage display has been used in the last 20 years in the identification of protein-ligands and protein-protein interactions, uncovering relevant molecular recognition events. Rate-limiting steps of combinatorial phage display library selection are (i) the counting of transducing units and (ii) the sequencing of the encoded displayed ligands. Here, we adapted emerging genomic technologies to minimize such challenges. We gained efficiency by applying in tandem real-time PCR for rapid quantification to enable bacteria-free phage display library screening, and added phage DNA next-generation sequencing for large-scale ligand analysis, reporting a fully integrated set of high-throughput quantitative and analytical tools. The approach is far less labor-intensive and allows rigorous quantification; for medical applications, including selections in patients, it also represents an advance for quantitative distribution analysis and ligand identification of hundreds of thousands of targeted particles from patient-derived biopsy or autopsy in a longer timeframe post library administration. Additional advantages over current methods include increased sensitivity, less variability, enhanced linearity, scalability, and accuracy at much lower cost. Sequences obtained by qPhage plus pyrosequencing were similar to a dataset produced from conventional Sanger-sequenced transducing-units (TU), with no biases due to GC content, codon usage, and amino acid or peptide frequency. These tools allow phage display selection and ligand analysis at >1,000-fold faster rate, and reduce costs approximately 250-fold for generating 10(6) ligand sequences. Our analyses demonstrates that whereas this approach correlates with the traditional colony-counting, it is also capable of a much larger sampling, allowing a faster, less expensive, more accurate and consistent analysis of phage enrichment. Overall, qPhage plus pyrosequencing is superior to TU-counting plus Sanger sequencing and is

    Topological insulators can exhibit strong magneto-electric effects when their time-reversal symmetry is broken. In this Letter we consider the magneto-optical Kerr and Faraday effects of a topological insulator thin film weakly exchange coupled to a ferromagnet. We find that its Faraday rotation has a universal value at low frequencies θF=tan(-1)α, where α is the vacuum fine structure constant, and that it has a giant Kerr rotation θK=π/2. These properties follow from a delicate interplay between thin-film cavity confinement and the surface Hall conductivity of a topological insulator's helical quasiparticles.

  17. Harnessing Local Immunity for an Effective Universal Swine Influenza Vaccine.

    Science.gov (United States)

    Tchilian, Elma; Holzer, Barbara

    2017-05-05

    Influenza A virus infections are a global health threat to humans and are endemic in pigs, contributing to decreased weight gain and suboptimal reproductive performance. Pigs are also a source of new viruses of mixed swine, avian, and human origin, potentially capable of initiating human pandemics. Current inactivated vaccines induce neutralising antibody against the immunising strain but rapid escape occurs through antigenic drift of the surface glycoproteins. However, it is known that prior infection provides a degree of cross-protective immunity mediated by cellular immune mechanisms directed at the more conserved internal viral proteins. Here we review new data that emphasises the importance of local immunity in cross-protection and the role of the recently defined tissue-resident memory T cells, as well as locally-produced, and sometimes cross-reactive, antibody. Optimal induction of local immunity may require aerosol delivery of live vaccines, but it remains unclear how long protective local immunity persists. Nevertheless, a universal vaccine might be extremely useful for disease prevention in the face of a pandemic. As a natural host for influenza A viruses, pigs are both a target for a universal vaccine and an excellent model for developing human influenza vaccines.

    Full Text Available Pulmonary function testing is a physiological test that measures how an individual inhales or exhales volumes of air as a function of time. Smoking is greatly associated with reduction of pulmonary function. This research is aimed to estimate the values of peak expiratory flow (PEF, forced expiratory volume in first second (FEV1, forced vital capacity (FVC and ratio between FEV1/FVC among smoking and non-smoking students in Universiti Tun Hussein Onn Malaysia. Smoking is often related to obstructive disorder with low value of FVC, FEV1 and FEV1/FVC. These pulmonary functions were analyzed based on several variables such as; the number of cigarette smoked per day, duration of smoking, age, and body mass index (BMI values. 70 healthy volunteers consist of smoking and non- smoking students was selected through several sessions. Students were interviewed to answer questionnaire on demographic, lifestyles and their smoking habit. The pulmonary function tests were conducted according to American Thoracic Society (ATS standards. The results of the pulmonary functions were analyzed by using SPSS software to compare the pulmonary functions between the smoker and the non-smoker students. The results of the studies showed that the number of cigarettes smoked by respondent and the BMI values were the significant predictors of the decrease in FEV1/FVC values among university students

  3. Modular invariance, universality and crossover in the quantum Hall effect

    International Nuclear Information System (INIS)

    Dolan, Brian P.

    1999-01-01

    An analytic form for the conductivity tensor in crossover between two quantum Hall plateaux is derived, which appears to be in good agreement with existing experimental data. The derivation relies on an assumed symmetry between quantum Hall states, a generalisation of the law of corresponding states from rational filling factors to complex conductivity, which has a mathematical expression in terms of an action of the modular group on the upper-half complex conductivity plane. This symmetry implies universality in quantum Hall crossovers. The assumption that the β-function for the complex conductivity is a complex analytic function, together with some experimental constraints, results in an analytic expression for the crossover, as a function of the external magnetic field

    Full Text Available Student retention is a key concern in tertiary education enabling programs with research showing that early engagement leads to higher completion rates (Hodges et al., 2013. But how do students new to university education learn how to engage effectively? This article outlines an engagement framework that foregrounds Guidance, Encouragement, Modelling and Structure (GEMS as a holistic approach to facilitating effective student engagement. This framework was developed from qualitative data gleaned from students enrolled in the Preparing for Success Program at Southern Cross University, New South Wales, Australia. The findings from the students indicate that the GEMS framework activates student potential and enables them to use existing knowledge and experience to not only deepen and broaden their learning but also successfully prepare for further study.

    use of virtual reality and commercial gaming systems (VR/gaming) at home by older adults is receiving attention as a means of enabling physical activity. to summarise evidence for the effectiveness and feasibility of VR/gaming system utilisation by older adults at home for enabling physical activity to improve impairments, activity limitations or participation. a systematic review searching 12 electronic databases from 1 January 2000-10 July 2012 using key search terms. Two independent reviewers screened yield articles using pre-determined selection criteria, extracted data using customised forms and applied the Cochrane Collaboration Risk of Bias Tool and the Downs and Black Checklist to rate study quality. fourteen studies investigating the effects of VR/gaming system use by healthy older adults and people with neurological conditions on activity limitations, body functions and physical impairments and cognitive and emotional well-being met the selection criteria. Study quality ratings were low and, therefore, evidence was not strong enough to conclude that interventions were effective. Feasibility was inconsistently reported in studies. Where feasibility was discussed, strong retention (≥70%) and adherence (≥64%) was reported. Initial assistance to use the technologies, and the need for monitoring exertion, aggravation of musculoskeletal symptoms and falls risk were reported. existing evidence to support the feasibility and effectiveness VR/gaming systems use by older adults at home to enable physical activity to address impairments, activity limitations and participation is weak with a high risk of bias. The findings of this review may inform future, more rigorous research.

  6. Hypersingular integral equations, waveguiding effects in Cantorian Universe and genesis of large scale structures

    Iovane, G.; Giordano, P.

    2005-01-01

    In this work we introduce the hypersingular integral equations and analyze a realistic model of gravitational waveguides on a cantorian space-time. A waveguiding effect is considered with respect to the large scale structure of the Universe, where the structure formation appears as if it were a classically self-similar random process at all astrophysical scales. The result is that it seems we live in an El Naschie's o (∞) Cantorian space-time, where gravitational lensing and waveguiding effects can explain the appearing Universe. In particular, we consider filamentary and planar large scale structures as possible refraction channels for electromagnetic radiation coming from cosmological structures. From this vision the Universe appears like a large self-similar adaptive mirrors set, thanks to three numerical simulations. Consequently, an infinite Universe is just an optical illusion that is produced by mirroring effects connected with the large scale structure of a finite and not a large Universe

    We studied the effects of hardwood-derived biochar (BC) and the phytohormone-producing endophyte Galactomyces geotrichum WLL1 in soybean (Glycine max (L.) Merr.) with respect to basic, macro- and micronutrient uptakes and assimilations, and their subsequent effects on the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity. The assimilation of basic nutrients such as nitrogen was up-regulated, leaving carbon, oxygen, and hydrogen unaffected in BC+G. geotrichum-treated soybean plants. In comparison, the uptakes of macro- and micronutrients fluctuated in the individual or co-application of BC and G. geotrichum in soybean plant organs and rhizospheric substrate. Moreover, the same attribute was recorded for the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and DPPH-scavenging activity. Collectively, these results showed that BC+G. geotrichum-treated soybean yielded better results than did the plants treated with individual applications. It was concluded that BC is an additional nutriment source and that the G. geotrichum acts as a plant biostimulating source and the effects of both are additive towards plant growth promotion. Strategies involving the incorporation of BC and endophytic symbiosis may help achieve eco-friendly agricultural production, thus reducing the excessive use of chemical agents.

In accordance with this purpose, a study for academicians that carry out their duties as executives virtually in two state universities one of which (Y takes place among entrepreneur and entrepreneurial university index while another (X doesn't take place within this index was conducted. The results of the questionnaires which tried to measure the entrepreneurial university perception and industrial and organizational psychology were analyzed with correlation analysis, multiple regression analysis, Kruskal-Wallis H Test and Mann-Whitney U test within the scope of SPSS program. As a result of the correlation analysis that was conducted for both of the samplings, a significant relationship was detected between negative and positive industrial and organizational psychology and entrepreneurial university perception. As a result of the regression analysis that was conducted for the sample obtained from X university, it was determined that the psychological output that had the most effect on the entrepreneurship university perception of the executives was motivation while the negative output that had the most effect was the intention to quit the job. As a result of the regression analysis that was conducted for the sample obtained from the Y University, it was detected that the positive output that had the most effect on the entrepreneurial university conception of the executives was motivation, while the negative output that had the most effect was job stress. As a result of the comparison of both examples, the fundamental psychological factor that intensified the entrepreneurial university perception was high motivation.

The effect of training was studied using a combination of different levels of psychological readiness and the biosocial background of the trainees to predict the psychological traits and participating behavior after the training. The study employed experimental research. The sample consisted of Lampang Rajabhat University sophomores, who were randomly assigned into 4 groups each of which consisted of 30 students with 3 experimental groups and 1 control group. The instruments were the training package and rating scale questionnaires. The statistics used for testing the hypothesis were analysis of variance, Scheffe's method, and multiple regression analysis. The findings revealed that the effects of training using a package of different components were (1 integrated psychological training together with integrated skills tended to yield the best results when evaluated immediately and one month after the training on students' attitudes and behaviors, (2 the integrated psychological training yielded better results than the other types of training regarding the students' readiness to participate in institutional activities; and (3integrated skill training yielded better results than any other kind of training on students' achievement motivation and intention for participating in activities when evaluated immediately. Other findings were that the level of a family's income was a combinative factor affecting the training regarding psychological traits training, attitudes, and behaviors of students when participating in the institutional activities. Finally, groups of psychological factors and situational factors together with groups of factors measured after the training predicted student's attitude and behavior when participating in the activities better than only one group of

    Full Text Available The current study examined the relationship between students' personal well-being and their learning achievement during university study, and whether such relationship would be mediated or moderated by university engagement. A total of 434 university students from one public university in Hong Kong participated in the study. The participants completed an online survey consisting of personal well-being (cognitive behavioral competence and general positive youth development, university engagement, and learning achievement measures (personal growth, and accumulated GPA as academic achievement at four time points with a 1-year interval. Results showed that personal well-being measured at the beginning of university study positively predicted students' personal growth and academic achievement after 3 years' study. While the internal dimensions of university engagement (academic challenge and learning with peers showed longitudinal significant mediational effect, the external dimensions (experience with faculty and campus environment did not have significant longitudinal moderating effect. Nevertheless, external dimensions of student engagement also showed direct effect on personal growth and academic achievement. The long-standing positive effects of personal well-being on university engagement and subsequently, learning achievement during university years call for more attention to the promotion of holistic development among university students in Hong Kong.

    Comparative Effectiveness Research (CER) has the potential to transform the current healthcare delivery system by identifying the most effective medical and surgical treatments, diagnostic tests, disease prevention methods and ways to deliver care for specific clinical conditions. To be successful, such research requires the identification, capture, aggregation, integration, and analysis of disparate data sources held by different institutions with diverse representations of the relevant clinical events. In an effort to address these diverse demands, there have been multiple new designs and implementations of informatics platforms that provide access to electronic clinical data and the governance infrastructure required for inter-institutional CER. The goal of this manuscript is to help investigators understand why these informatics platforms are required and to compare and contrast six, large-scale, recently funded, CER-focused informatics platform development efforts. We utilized an 8-dimension, socio-technical model of health information technology use to help guide our work. We identified six generic steps that are necessary in any distributed, multi-institutional CER project: data identification, extraction, modeling, aggregation, analysis, and dissemination. We expect that over the next several years these projects will provide answers to many important, and heretofore unanswerable, clinical research questions. PMID:22692259

    Sound understanding by end-users (health professionals and support staff) of key e-health principles and challenges is essential for the safe, effective, and sustainable use of health informatics systems. This is separate from, and ideally a precursor to, training on a specific system. However, hitherto this aspect has been little understood or addressed. Over the last few years, the concept of a customised Health Supplement to the well-established European/International Computer Driving Licence has progressed from idea to reality, through initial support for consultation by the then UK NHS Information Authority, followed by establishment of an international Expert Group by the global ECDL/ICDL Foundation. As a result, the ECDL/ICDL Foundation has developed a formal syllabus. This paper reports successful piloting, and progress in the development of local training and testing materials and national implementation plans, in three countries on two continents.

    The ability to incorporate rigid but high-performance nano-scale non-planar complementary metal-oxide semiconductor (CMOS) electronics with curvilinear, irregular, or asymmetric shapes and surfaces is an arduous but timely challenge in enabling the production of wearable electronics with an in-situ information-processing ability in the digital world. Therefore, we are demonstrating a soft-material enabled double-transfer-based process to integrate flexible, silicon-based, nano-scale, non-planar, fin-shaped field effect transistors (FinFETs) and planar metal-oxide-semiconductor field effect transistors (MOSFETs) on various asymmetric surfaces to study their compatibility and enhanced applicability in various emerging fields. FinFET devices feature sub-20 nm dimensions and state-of-the-art, high-κ/metal gate stack, showing no performance alteration after the transfer process. A further analysis of the transferred MOSFET devices, featuring 1 μm gate length exhibits ION ~70 μA/μm (VDS = 2 V, VGS = 2 V) and a low sub-threshold swing of around 90 mV/dec, proving that a soft interfacial material can act both as a strong adhesion/interposing layer between devices and final substrate as well as a means to reduce strain, which ultimately helps maintain the device’s performance with insignificant deterioration even at a high bending state.

  15. Universal relationship connecting various two-body effective residual interactions

    Starting from a momentum space analysis of the two-body matrix elements, a relation has been established between the size of the model space actually used in a specific calculation and the relevant properties of the effective residual interaction. It turns out that the two-body transition density acts like a filter function on the Fourier transform of the force; it exhibits a distinct structure which clearly reflects the size and the detailed properties of the configuration space actually used. From an investigation of this filter function an equivalence criterion for different effective residual two-body interactions has been established both for closed and open shell nuclei. This result can be used to construct simple although realistic effective forces. As an example, a model for a separable residual interaction is proposed in which the corresponding parameters are being clearly related to the nuclear radius (i.e., the mass number), to the quantum numbers (i.e., the angular momentum) of the state under consideration and to the size of the configuration space used. For a number of examples this force has been applied successfully for the description of low energy properties of both closed and open shell nuclei

  17. Measuring macro-level effects of the global economic recession on university-industry research cooperation

    2016-07-01

    The 2007/2008 financial crisis, and ensuing economic recession, had a direct negative effect on university-industry research cooperation in the OECD countries and other economies – it diminished the number of university-industry co-authored research publications (UICs) during the period 2008-13 by 7%. It also changed the relationship between national business expenditure on R&D and UIC output levels. Before the recession the relationship was negative, but became positive during the years 2008-2013. The few countries where business expenditure on R&D increased during recession saw UIC numbers rise. This moderating effect of the recession applies only to ‘domestic UICs’, where universities cooperated with business companies located in the same country. Micro-level research is needed to assess the contributing effects on large university-industry R&D consortia on both domestic and international collaboration patterns. (Author)

  18. Mixed heavy-light matching in the Universal One-Loop Effective Action

    Recently, a general result for evaluating the path integral at one loop was obtained in the form of the Universal One-Loop Effective Action. It may be used to derive effective field theory operators of dimensions up to six, by evaluating the traces of matrices in this expression, with the mass dependence encapsulated in the universal coefficients. Here we show that it can account for loops of mixed heavy-light particles in the matching procedure. Our prescription for computing these mixed contributions to the Wilson coefficients is conceptually simple. Moreover it has the advantage of maintaining the universal structure of the effective action, which we illustrate using the example of integrating out a heavy electroweak triplet scalar coupling to a light Higgs doublet. Finally we also identify new structures that were previously neglected in the universal results.

    Supersymmetric theories supplemented by an underlying flavor-symmetry G_f provide a rich playground for model building aimed at explaining the flavor structure of the Standard Model. In the case where supersymmetry breaking is mediated by gravity, the soft-breaking Lagrangian typically exhibits large tree-level flavor violating effects, even if it stems from an ultraviolet flavor-conserving origin. Building on previous work, we continue our phenomenological analysis of these models with a particular emphasis on leptonic flavor observables. We consider three representative models which aim to explain the flavor structure of the lepton sector, with symmetry groups G_f=Δ (27) , A 4, and S 3.

    Is our universe an accident of nature. The mysterious coincidences underlying the structure and properties of the universe that we inhabit are examined. This is the first book for the non-specialist reader to present in depth the provocative hypothesis that the structure of the physical world is exceedingly contrived in its appearance. A survey is presented of the range of apparently miraculous accidents of nature that have enabled the universe to evolve its familiar structures: atoms, stars, galaxies, and life itself. This book concludes with an investigation of the so-called 'anthropic principle' which postulates that 'miraculous coincidences' are inevitable in any universe containing conscious observers. This thesis of a cosmic biological selection effect will both reassure and enrage readers, the very existence of whom may be related to fine tuning in the laws of physics. (author)

  8. Waveguiding and mirroring effects in stochastic self-similar and Cantorian ε(∞) universe

    International Nuclear Information System (INIS)

    Iovane, G.

    2005-01-01

    A waveguiding effect is considered with respect to the large scale structure of the Universe, where the structures formation appears as if it were a classically self-similar random process at all astrophysical scales. The result is that it seems we live in an El Naschie's ε (∞) Cantorian space-time, where gravitational lensing and waveguiding effects can explain the appearing Universe. In particular, we consider filamentary and planar large scale structures as possible refraction channels for electromagnetic radiation coming from cosmological structures. From this vision the Universe appears like a large self-similar adaptive mirrors set. Consequently, an infinite Universe is just an optical illusion that is produced by mirroring effects connected with the large scale structure of a finite and not so large Universe. Thanks to the presented analytical model supported by a numerical simulation, it is possible to explain the quasar luminosity distribution and the presence of 'twin' or 'brother' objects. More generally, the infinity and the abundance of astrophysical objects could be just a mirroring effect due to the peculiar self-similarity of the Universe

    2011-01-01

    The quantum dynamics of the linearly polarized Gowdy T 3 model (compact inhomogeneous universes admitting linearly polarized gravitational waves) is analyzed within loop quantum cosmology by means of an effective dynamics. The analysis, performed via analytical and numerical methods, proves that the behavior found in the evolution of vacuum (homogeneous) Bianchi I universes is preserved qualitatively also in the presence of inhomogeneities. More precisely, the initial singularity is replaced by a big bounce which joins deterministically two large classical universes. In addition, we show that the size of the universe at the bounce is at least of the same order of magnitude (roughly speaking) as the size of the corresponding homogeneous universe obtained in the absence of gravitational waves. In particular, a precise lower bound for the ratio of these two sizes is found. Finally, the comparison of the amplitudes of the gravitational wave modes in the distant future and past shows that, statistically (i.e., for large samples of universes), the difference in amplitude is enhanced for nearly homogeneous universes, whereas this difference vanishes in inhomogeneity-dominated cases. The presented analysis constitutes the first systematic effective study of an inhomogeneous system within loop quantum cosmology, and it proves the robustness of the results obtained for homogeneous cosmologies in this context.

  10. The Effect of Public and Private Decisions on University Governance on the Transnational Relations of American-Associated Universities in the Middle East

    Full Text Available This paper analyzes the effect of public and private decisions on university governance on how historic and current American-associated universities in the Middle East have and continue to connect as transnational actors with a multitude of public, private and civil society actors in American society. These universities are the classic missionary universities in Beirut and Cairo (the American University of Beirut, Lebanese American University and the American University in Cairo as well as the many branch campuses and new universities with American accreditation or partnership which have appeared especially in the Gulf States. The ability of these universities to engage with actors in American society and the Middle Eastern host society is explained by their model of governance highlighting public and private decisions on primarily owner-ship structure and non- or for-profit status. Affiliated, non-profit status explains academic reputation, while proprietary, for-profit status is detrimental. Academic reputation is the basis of the relationships these universities maintain with American private, public and civil society actors.

    We propose and experimentally demonstrate a multiuser orthogonal frequency-division multiple access passive optical network (OFDMA-PON) with source-free optical network units (ONUs), enabled by tunable optical frequency comb generation technology. By cascading a phase modulator (PM) and an intensity modulator and dynamically controlling the peak-to-peak voltage of a PM driven signal, a tunable optical frequency comb source can be generated. It is utilized to assist the configuration of a multiple source-free ONUs enhanced OFDMA-PON where simultaneous and interference-free multiuser upstream transmission over a single wavelength can be efficiently supported. The proposed multiuser OFDMA-PON is scalable and cost effective, and its feasibility is successfully verified by experiment.

    Most of the literatures related to university-industry (U-I) and technology transfer assume that the collaboration particularly the U-I joint research is beneficial to both university and industry which as a result underpins the sustainable development of economics and living standards of developed and developing countries. The U-I joint research for photovoltaic technology transfer in a developing country like Thailand should have been increased considering the fact that (i) the government implemented various strategies to support the renewable energy research and market development, (ii) the university aimed to be ''research-based university and (iii) the Thai photovoltaic industry struggle for competitiveness and survival in the global market. However, evidence revealed that the university and industry conducted little number of U-I joint projects. In this paper, we investigate the factors influencing the effective U-I joint research for photovoltaic technology transfer (UIJRPTT). In an attempt to better understand the influence of the factors, the path model with factors related to characteristics and perspectives of the university and the industry as well as joint research mechanism and their linkages to higher growth and improved economic and quality performance of the U-I joint research is developed and validated. The developed model empirically explains interaction between the factors and the outcome factors and can assist the government, the university and the industry to devise target strategies to improve the growth and performance of UIJRPTT.

    To assess the cost-effectiveness of universal screening for thyroid disease in pregnant women in Spain as compared to high risk screening and no screening. A decision-analytic model comparing the incremental cost per quality-adjusted life year (QALY) of universal screening versus high risk screening and versus no screening. was used for the pregnancy and postpartum period. Probabilities from randomized controlled trials were considered for adverse obstetrical outcomes. A Markov model was used to assess the lifetime period after the first postpartum year and account for development of overt hypothyroidism. The main assumptions in the model and use of resources were assessed by local clinical experts. The analysis considered direct healthcare costs only. Universal screening gained .011 QALYs over high risk screening and .014 QALYS over no screening. Total direct costs per patient were €5,786 for universal screening, €5,791 for high risk screening, and €5,781 for no screening. Universal screening was dominant compared to risk-based screening and a very cost-effective alternative as compared to no screening. Use of universal screening instead of high risk screening would result in €2,653,854 annual savings for the Spanish National Health System. Universal screening for thyroid disease in pregnant women in the first trimester is dominant in Spain as compared to risk-based screening, and is cost-effective as compared to no screening (incremental cost-effectiveness ratio of €374 per QALY). Moreover, it allows diagnosing and treating cases of clinical and subclinical hypothyroidism that may not be detected when only high-risk women are screened. Copyright © 2014 SEEN.

    A high-performance top-gated graphene field-effect transistor (FET) with excellent mechanical flexibility is demonstrated by implementing a surface-energy-engineered copolymer gate dielectric via a solvent-free process called initiated chemical vapor deposition. The ultrathin, flexible copolymer dielectric is synthesized from two monomers composed of 1,3,5-trimethyl-1,3,5-trivinyl cyclotrisiloxane and 1-vinylimidazole (VIDZ). The copolymer dielectric enables the graphene device to exhibit excellent dielectric performance and substantially enhanced mechanical flexibility. The p-doping level of the graphene can be tuned by varying the polar VIDZ fraction in the copolymer dielectric, and the Dirac voltage (V Dirac ) of the graphene FET can thus be systematically controlled. In particular, the V Dirac approaches neutrality with higher VIDZ concentrations in the copolymer dielectric, which minimizes the carrier scattering and thereby improves the charge transport of the graphene device. As a result, the graphene FET with 20 nm thick copolymer dielectrics exhibits field-effect hole and electron mobility values of over 7200 and 3800 cm 2 V -1 s -1 , respectively, at room temperature. These electrical characteristics remain unchanged even at the 1 mm bending radius, corresponding to a tensile strain of 1.28%. The formed gate stack with the copolymer gate dielectric is further investigated for high-frequency flexible device applications. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  10. Impaired drug absorption due to high stomach pH: a review of strategies for mitigation of such effect to enable pharmaceutical product development.

    Mitra, Amitava; Kesisoglou, Filippos

    2013-11-04

    Published reports have clearly shown that weakly basic drugs which have low solubility at high pH could have impaired absorption in patients with high gastric pH thus leading to reduced and variable bioavailability. Since such reduction in exposure can lead to significant loss of efficacy, it is imperative to (1) understand the behavior of the compound as a function of stomach pH to inform of any risk of bioavailability loss in clinical studies and (2) develop a robust formulation which can provide adequate exposure in achlorhydric patients. In this review paper, we provide an overview of the factors that can cause high gastric pH in human, discuss clinical and preclinical pharmacokinetic data for weak bases under conditions of normal and high gastric pH, and give examples of formulation strategies to minimize or mitigate the reduced absorption of weakly basic drugs under high gastric pH conditions. It should be noted that the ability to overcome pH sensitivity issues is highly compound dependent and there are no obvious and general solutions to overcome such effect. Further, we discuss, along with several examples, the use of biopharmaceutical tools such as in vitro dissolution, absorption modeling, and gastric pH modified animal models to assess absorption risk of weak bases in high gastric pH and also the use of these tools to enable development of formulations to mitigate such effects.

    There are some tensions between high-level policy definitions of “digital literacy” and actual teaching practice. We need to find workable definitions of digital literacy; obtain a better understanding of what digital literacy might look like in practice; and identify pedagogical approaches, which...... support teachers in designing digital literacy learning. We suggest that frameworks such as Problem Based Learning (PBL) are approaches that enable digital literacy learning because they provide good settings for engaging with digital literacy. We illustrate this through analysis of a case. Furthermore......, these operate on a meso-level mediating between high-level concepts of digital literacy and classroom practice....

    Full Text Available Abstract Background Neonatal hearing screening (NHS has been routinely offered as a vital component of early childhood care in developed countries, whereas such a screening program is still at the pilot or preliminary stage as regards its nationwide implementation in developing countries. To provide significant evidence for health policy making in China, this study aims to determine the cost-effectiveness of NHS program implementation in case of eight provinces of China. Methods A cost-effectiveness model was conducted and all neonates annually born from 2007 to 2009 in eight provinces of China were simulated in this model. The model parameters were estimated from the established databases in the general hospitals or maternal and child health hospitals of these eight provinces, supplemented from the published literature. The model estimated changes in program implementation costs, disability-adjusted life years (DALYs, average cost-effectiveness ratio (ACER, and incremental cost-effectiveness ratio (ICER for universal screening compared to targeted screening in eight provinces. Results and discussion A multivariate sensitivity analysis was performed to determine uncertainty in health effect estimates and cost-effectiveness ratios using a probabilistic modeling technique. Targeted strategy trended to be cost-effective in Guangxi, Jiangxi, Henan, Guangdong, Zhejiang, Hebei, Shandong, and Beijing from the level of 9%, 9%, 8%, 4%, 3%, 7%, 5%, and 2%, respectively; while universal strategy trended to be cost-effective in those provinces from the level of 70%, 70%, 48%, 10%, 8%, 28%, 15%, 4%, respectively. This study showed although there was a huge disparity in the implementation of the NHS program in the surveyed provinces, both universal strategy and targeted strategy showed cost-effectiveness in those relatively developed provinces, while neither of the screening strategy showed cost-effectiveness in those relatively developing provinces.

    The combined team of GE Global Research, Federal Express, National Renewable Energy Laboratory, and Consolidated Edison has successfully achieved the established goals contained within the Department of Energy’s Smart Grid Capable Electric Vehicle Supply Equipment funding opportunity. The final program product, shown charging two vehicles in Figure 1, reduces by nearly 50% the total installed system cost of the electric vehicle supply equipment (EVSE) as well as enabling a host of new Smart Grid enabled features. These include bi-directional communications, load control, utility message exchange and transaction management information. Using the new charging system, Utilities or energy service providers will now be able to monitor transportation related electrical loads on their distribution networks, send load control commands or preferences to individual systems, and then see measured responses. Installation owners will be able to authorize usage of the stations, monitor operations, and optimally control their electricity consumption. These features and cost reductions have been developed through a total system design solution.

    Diarrhea is one of the world's leading killers of children, and globally, rotavirus is the most common cause of severe diarrhea among under 5 children. In Bangladesh, rotavirus kills nearly 6,000 under 5 children in each year. To reduce the burden of childhood rotavirus diseases, universal rotavirus vaccination is recommended by World Health Organization. The objective of this study is to assess the cost-effectiveness of introducing universal childhood rotavirus vaccination with the newly developed ROTAVAC vaccine in national Expanded Programme of Immunization in Bangladesh. We developed a decision model to examine the potential impact of vaccination in Bangladesh and to examine the effect if the vaccination is applied in the nationwide immunization program schedule. Introduction of childhood universal rotavirus vaccination in Bangladesh scenario appears as highly cost-effective and would offer substantial future benefits for the young population if vaccinated today. The cost per DALY averted of introducing the rotavirus vaccine compared with status quo is approximately US$ 740.27 and US$ 728.67 per DALY averted from the health system and societal perspective respectively which is "very cost-effective" using GDP threshold level according to World Health Organization definition. The results of this analysis seek to contribute to an evidence-based recommendation about the introduction of universal rotavirus vaccination in national Expanded Programme of Immunization (EPI) in Bangladesh.

    The increasing prevalence of tattoos provoked safety concerns with respect to particle distribution and effects inside the human body. We used skin and lymphatic tissues from human corpses to address local biokinetics by means of synchrotron X-ray fluorescence (XRF) techniques at both the micro (μ) and nano (ν) scale. Additional advanced mass spectrometry-based methodology enabled to demonstrate simultaneous transport of organic pigments, heavy metals and titanium dioxide from skin to regional lymph nodes. Among these compounds, organic pigments displayed the broadest size range with smallest species preferentially reaching the lymph nodes. Using synchrotron μ-FTIR analysis we were also able to detect ultrastructural changes of the tissue adjacent to tattoo particles through altered amide I α-helix to β-sheet protein ratios and elevated lipid contents. Altogether we report strong evidence for both migration and long-term deposition of toxic elements and tattoo pigments as well as for conformational alterations of biomolecules that likely contribute to cutaneous inflammation and other adversities upon tattooing.

    2013-03-01

    During breast carcinoma progression, the three-dimensional (3D) microenvironment is continuously remodeled, and changes in the composition of the extracellular matrix (ECM) occur. High throughput screening platforms have been used to decipher the complexity of the microenvironment and to identify ECM components responsible for cancer progression. However, traditional screening platforms are typically limited to two-dimensional (2D) cultures, and often exclude the influence of ECM and stromal components. In this work, a system that integrates 3-dimensional cell culture techniques with an automated microfluidic platform was used to create a new ECM screening platform that cultures cells in more physiologically relevant 3D in vitro microenvironments containing stromal cells and different ECM molecules. This new ECM screening platform was used to culture T47D breast carcinoma cells in mono- and co-culture with human mammary fibroblasts (HMF) with seven combinations of three different ECM proteins (collagen, fibronectin, laminin). Differences in the morphology of T47D clusters, and the proliferation of T47D cells were found in ECM compositions rich in fibronectin or laminin. In addition, an MMP enzyme activity inhibition screening showed the capabilities of the platform for small molecule screening. The platform presented in this work enables screening for the effects of matrix and stromal compositions and show promises for providing new insights in the identification of key ECM components involved in breast cancer.

    Recent work has shown that graphene, a 2D electronic material amenable to the planar semiconductor fabrication processing, possesses tunable electronic material properties potentially far superior to metals and other standard semiconductors. Despite its phenomenal electronic properties, focused research is still required to develop techniques for depositing and synthesizing graphene over large areas, thereby enabling the reproducible mass-fabrication of graphene-based devices. To address these issues, we combined an array of growth approaches and characterization resources to investigate several innovative and synergistic approaches for the synthesis of high quality graphene films on technologically relevant substrate (SiC and metals). Our work focused on developing the fundamental scientific understanding necessary to generate large-area graphene films that exhibit highly uniform electronic properties and record carrier mobility, as well as developing techniques to transfer graphene onto other substrates.

    2017-09-01

    Full Text Available Using a fully-fledged formulation of gauge field theory deformed by the spacetime noncommutativity, we study its impact on relic neutrino direct detection, as proposed recently by the PTOLEMY experiment. The noncommutative background tends to influence the propagating neutrinos by providing them with a tree-level vector-like coupling to photons, enabling thus otherwise sterile right-handed (RH neutrinos to be thermally produced in the early universe. Such a new component in the universe's background radiation has been switched today to the almost fully active sea of non-relativistic neutrinos, exerting consequently some impact on the capture on tritium at PTOLEMY. The peculiarities of our nonperturbative approach tend to reflect in the cosmology as well, upon the appearances of the coupling temperature, above which RH neutrinos stay permanently decoupled from thermal environment. This entails the maximal scale of noncommutativity as well, being of order of 10−4MPl, above which there is no impact whatsoever on the capture rates at PTOLEMY. The latter represents an exceptional upper bound on the scale of noncommutativity coming from phenomenology.

    Masri, Mazyrah; Wan Ahmad, Wan Fatimah; Nordin, Shahrina Md.; Sulaiman, Suziah

    This paper highlights the effect of visual of a multimedia courseware, Black Cat Courseware (BC-C), developed for learning literature at a pre-university level in University Teknologi PETRONAS (UTP). The contents of the courseware are based on a Black Cat story which is covered in an English course at the university. The objective of this paper is to evaluate the usability and effectiveness of BC-C. A total of sixty foundation students were involved in the study. Quasi-experimental design was employed, forming two groups: experimental and control groups. The experimental group had to interact with BC-C as part of the learning activities while the control group used the conventional learning methods. The results indicate that the experimental group achieved a statistically significant compared to the control group in understanding the Black Cat story. The study result also proves that the effect of visual increases the students' performances in literature learning at a pre-university level.

  7. Achieving Effective Universal Health Coverage And Diagonal Approaches To Care For Chronic Illnesses.

    2015-09-01

    Health systems in low- and middle-income countries were designed to provide episodic care for acute conditions. However, the burden of disease has shifted to be overwhelmingly dominated by chronic conditions and illnesses that require health systems to function in an integrated manner across a spectrum of disease stages from prevention to palliation. Low- and middle-income countries are also aiming to ensure health care access for all through universal health coverage. This article proposes a framework of effective universal health coverage intended to meet the challenge of chronic illnesses. It outlines strategies to strengthen health systems through a "diagonal approach." We argue that the core challenge to health systems is chronicity of illness that requires ongoing and long-term health care. The example of breast cancer within the broader context of health system reform in Mexico is presented to illustrate effective universal health coverage along the chronic disease continuum and across health systems functions. The article concludes with recommendations to strengthen health systems in order to achieve effective universal health coverage. Project HOPE—The People-to-People Health Foundation, Inc.

    To evaluate the consumption, prevalence, side effects and awareness of energy drinks among female university students in Saudi Arabia. A quantitative research design was implied with sample size of 358 female students, recruited from Prince Sattam bin Abdulaziz University. The data, gathered through self-administered questionnaire, was analyzed through SPSS version 20.0 with p value energy drink consumers. The reasons for increased consumption of energy drinks mainly include giving company to friends (59.4%), better performance in exams (41.2%), and better concentration in studies (39.4%). The most common side effect was headache (32.3%), and the least was identified as allergy (2%). Only 39.4% and 29.9% of students acquired awareness regarding the harmful effects of energy drink consumption during pregnancy and breast feeding respectively. A significant proportion of female students at Prince Sattam bin Abdulaziz have reported to consume energy drinks regularly with several adverse effects. The government of Saudi Arabia should take serious initiatives towards organizing effective awareness programs specifically in universities and colleges to control the consumption of energy drinks and educate on the adverse effects.

    Diener, et al.'s 1985 Satisfaction With Life Scale was administered to 1749 adult Australians to examine differences between men and women, university students and nonuniversity students, and among 17- to 22-, 23- to 29-, and 30- to 40-yr.-olds. No significant differences in life-satisfaction emerged in relation to sex or university status, but age showed a significant effect as higher life-satisfaction characterized older subjects. No interactions were found for any combination of the three variables. The results are interpreted in terms of egalitarian sex-role ideologies regarding sex, status-specific criteria in the assessment and conceptualisation of life-satisfaction for university status, and maturity trends in viewing life events concerning age.

    Suicide is a leading cause of death among Japanese college and university students. Gatekeeper-training programs have been shown to improve detection and referral of individuals who are at risk of suicide by training non-mental-health professional persons. However, no studies have investigated the effectiveness of such programs in university settings in Japan. The aim of this study was to investigate the effectiveness of the gatekeeper-training program for administrative staff in Japanese universities. We developed a 2.5-h gatekeeper-training program based on the Mental Health First Aid program, which was originally developed for the general public. Seventy-six administrative staff at Hokkaido University participated in the program. Competence and confidence in managing suicide intervention, behavioral intention as a gatekeeper and attitude while handling suicidal students were measured by a self-reported questionnaire before, immediately after and a month after the program. We found a significant improvement in competence in the management of suicidal students. We also found improvements in confidence in management of suicidal students and behavioral intention as a gatekeeper after training, though questionnaires for those secondary outcomes were not validated. These improvements continued for a month. About 95% of the participants rated the program as useful or very useful and one-third of the participants had one or more chances to utilize their skills within a month. The current results suggest the positive effects of the training program in university settings in Japan. Future evaluation that includes comparison with standard didactic trainings and an assessment of long-term effectiveness are warranted. © 2015 The Authors.

     The aim of this study was to evaluate the effect of surface treatment and universal adhesive on the microshear bond strength of nanoparticle composite repairs.  One hundred and forty-four specimens were built with a nanofilled composite (Filtek Supreme Ultra, 3M ESPE). The surfaces of all the specimens were polished with SiC paper and stored in distilled water at 37°C for 14 days. Half of the specimens were then air abraded with Al 2 O 3 particles and cleaned with phosphoric acid. Polished specimens (P) and polished and air-abraded specimens (A), respectively, were randomly divided into two sets of six groups (n=12) according to the following treatments: hydrophobic adhesive only (PH and AH, respectively), silane and hydrophobic adhesive (PCH, ACH), methacryloyloxydecyl dihydrogen phosphate (MDP)-containing silane and hydrophobic adhesive (PMH, AMH), universal adhesive only (PU, AU), silane and universal adhesive (PCU, ACU), and MDP-containing silane and universal adhesive (PMU, AMU). A cylinder with the same composite resin (1.1-mm diameter) was bonded to the treated surfaces to simulate the repair. After 48 hours, the specimens were subjected to microshear testing in a universal testing machine. The failure area was analyzed under an optical microscope at 50× magnification to identify the failure type, and the data were analyzed by three-way analysis of variance and the Games-Howell test (α=0.05).  The variables "surface treatment" and "adhesive" showed statistically significant differences for psilane did not lead to a statistically significant increase in bond strength. Silane-containing universal adhesive on its own was as effective as any combination of silane and adhesive, particularly when applied on air-abraded surfaces.

    Full Text Available The number of males entering higher education via an enabling pathway is slowly increasing; yet, males still battle with the anti-intellectual attitude that is prevalent in regional areas of Australia. Previous research undertaken by the authors began exploring the factors that inhibited or enhanced the male experience within an enabling course. This paper expands upon this research with a deeper focus on the male experience through personalised accounts derived from individual interviews. Using qualitative methodology and narrative inquiry, the findings provide a deeper understanding of the issues that males of different ages face when creating a new identity as a university student. This paper shares insights into what motivated the male students to enter university via an enabling pathway; the actual personal experiences both positive and negative during this time; and the effect that this commitment to study had on them personally and the people around them. The lens of transformative theory underpins this research through exploring frames of reference that align with the students’ experiences. Portraiture prose shares the individual stories which are analysed and the key findings extrapolated.

    FLASH II is an upgrade to the existing free electron laser (FEL) FLASH. The echo-enabled harmonic generation (EEHG) scheme is proposed to be a potential seeding option of FLASH II. In this paper, the possibility of EEHG operation of FLASH II is investigated for the first time. With a combination of existing numerical codes, i.e. a laser-beam interaction code in an undulator (LBICU), a beam tracking code in a chicane (ELEGANT) and an universal FEL simulating code (GENESIS), the effects of beam energy chirp and coherent synchrotron radiation (CSR) on EEHG operation are studied as well. In addition, several interesting issues concerning EEHG simulation are discussed. (orig.)

    There are few randomized controlled trials on the effectiveness of palliative care interventions to improve the care of patients with advanced cancer. To determine the effect of a nursing-led intervention on quality of life, symptom intensity, mood, and resource use in patients with advanced cancer. Randomized controlled trial conducted from November 2003 through May 2008 of 322 patients with advanced cancer in a rural, National Cancer Institute-designated comprehensive cancer center in New Hampshire and affiliated outreach clinics and a VA medical center in Vermont. A multicomponent, psychoeducational intervention (Project ENABLE [Educate, Nurture, Advise, Before Life Ends]) conducted by advanced practice nurses consisting of 4 weekly educational sessions and monthly follow-up sessions until death or study completion (n = 161) vs usual care (n = 161). Quality of life was measured by the Functional Assessment of Chronic Illness Therapy for Palliative Care (score range, 0-184). Symptom intensity was measured by the Edmonton Symptom Assessment Scale (score range, 0-900). Mood was measured by the Center for Epidemiological Studies Depression Scale (range, 0-60). These measures were assessed at baseline, 1 month, and every 3 months until death or study completion. Intensity of service was measured as the number of days in the hospital and in the intensive care unit (ICU) and the number of emergency department visits recorded in the electronic medical record. A total of 322 participants with cancer of the gastrointestinal tract (41%; 67 in the usual care group vs 66 in the intervention group), lung (36%; 58 vs 59), genitourinary tract (12%; 20 vs 19), and breast (10%; 16 vs 17) were randomized. The estimated treatment effects (intervention minus usual care) for all participants were a mean (SE) of 4.6 (2) for quality of life (P = .02), -27.8 (15) for symptom intensity (P = .06), and -1.8 (0.81) for depressed mood (P = .02).

    2016-05-01

    Full Text Available Institutional theory argues that the isomorphic nature of quality management (QM practices leads to similar QM implementation and performance among QM-embedded firms. However, contingency theory questions such 'universal effectiveness of QM practices'. Considering these conflicting arguments, this study tests samples from the U.S. and China to examine whether the 'universal effectiveness of QM practices’ across national boundaries actually exists. First, the confirmatory factor analysis was performed to examine the validity of the survey instruments developed in this study. Then, the hypotheses were tested using the structural equation modeling (SEM analysis. The SEM test results indicated that the positive effect of behavioral QM on firm performance was more significant in the U.S. sample than in the China sample. The test results also presented that the relative effect of behavioral QM versus technical QM on firm performance was noticeably different in service firms, according to national economic maturity. The study’s findings demonstrated that a firm's contingency factors, such as national economic maturity and industry type, could result in the heterogeneous implementation of the firm’s TQM program; consequently, the findings weakened the 'universal effectiveness of QM practices'.

    The object of the 'Enabling Immersive Simulation for Complex Systems Analysis and Training' LDRD has been to research, design, and engineer a capability to develop simulations which (1) provide a rich, immersive interface for participation by real humans (exploiting existing high-performance game-engine technology wherever possible), and (2) can leverage Sandia's substantial investment in high-fidelity physical and cognitive models implemented in the Umbra simulation framework. We report here on these efforts. First, we describe the integration of Sandia's Umbra modular simulation framework with the open-source Delta3D game engine. Next, we report on Umbra's integration with Sandia's Cognitive Foundry, specifically to provide for learning behaviors for 'virtual teammates' directly from observed human behavior. Finally, we describe the integration of Delta3D with the ABL behavior engine, and report on research into establishing the theoretical framework that will be required to make use of tools like ABL to scale up to increasingly rich and realistic virtual characters.

    Scientists are taking advantage of the Internet and collaborative web technology to accelerate discovery in a massively connected, participative environment —a phenomenon referred to by some as Science 2.0. As a new way of doing science, this phenomenon has the potential to push science forward in a more efficient manner than was previously possible. The Grid-Enabled Measures (GEM) database has been conceptualized as an instantiation of Science 2.0 principles by the National Cancer Institute with two overarching goals: (1) Promote the use of standardized measures, which are tied to theoretically based constructs; and (2) Facilitate the ability to share harmonized data resulting from the use of standardized measures. This is done by creating an online venue connected to the Cancer Biomedical Informatics Grid (caBIG®) where a virtual community of researchers can collaborate together and come to consensus on measures by rating, commenting and viewing meta-data about the measures and associated constructs. This paper will describe the web 2.0 principles on which the GEM database is based, describe its functionality, and discuss some of the important issues involved with creating the GEM database, such as the role of mutually agreed-on ontologies (i.e., knowledge categories and the relationships among these categories— for data sharing).

    2008-04-01

    We construct a physical model to study the effects of dimensional reduction that might have taken place during the inflationary phase of the universe. The model we propose is a (1 + D)-dimensional ( D > 3), nonsingular, spatially homogeneous and isotropic Friedmann model. We consider dimensional reduction to take place in a stepwise manner and interpret each step as a phase transition. Independent of the details of the process of dimensional reduction, we impose suitable boundary conditions across the transitions and trace the effects of dimensional reduction to the currently observable parameters of the universe. In order to exhibit the cosmological features of the proposed model, we construct a (1 + 4)-dimensional toy model for both closed and open cases of Friedmann geometries. It is shown that in these models the universe makes transition into the lower dimension when the critical length parameter l 4,3, which signals dimensional reduction, reaches the Planck length in D = 3. The numerical models we present in this paper have the capability of making definite predictions about the cosmological parameters of the universe such as the Hubble parameter, age and density.

    Effective leadership is essential to passing through obstacles facing the health field.The current health care system in Iran has major problems and gaps in the field of effective leadership. The aim of this study was to evaluate hospital managers' leadership style through selfassessment and to determine the correlation between leadership styles with healthcare executives' leadership readiness and leadership effectiveness. In this cross-sectional study a self-administered questionnaire completed by all internal healthcare executives of all teaching and non-teaching hospitals affiliated to Iran University of Medical Sciences. Questionnaire was composed to determine demographic information, leadership style questions, leadership effectiveness and leadership readiness. Descriptive statistics and Pearson correlation coefficient were used for data analysis. According to the findings, the dominant style of healthcare executives was transformational leadership style (with a score of 4.34). The leadership effectiveness was estimated at about 4.36 that shows the appropriate level of leadership effectiveness. There was a significant correlation (correlation coefficient of 0.244) between leadership readiness and transformational leadership style (pleadership effectiveness with transformational (0.051) and transactional (0.216) styles. There was a correlation between leadership readiness and leadership effectiveness with leadership styles. Application of this research will be crucial to universities and healthcare executives. This study suggests that strengthening the scientific basis is essential for leadership readiness and leadership effectiveness in healthcare system.

    2005-08-01

    It is widely recognized that lectures continue to dominate college chemistry instruction, especially in developing countries, and that lectures limit student intellectual engagement. To address this concern, a General Chemistry course in a Philippine university was reconstructed to implement an instructional cycle consisting of three phases: a plenary or mini-lecture, seatwork activity, and a summary or closure. An expert instructor coached the instructors to improve their teaching. Two instructors were involved in pilot implementation and 13 instructors in a large-scale implementation. This article describes the instructors’ adoption of the instructional cycle using qualitative and quantitative methods that involved multiple data sources. The instructional cycle and intensive coaching enabled most instructors to change their practices, shift their focus from teaching to learning, and enhance their knowledge of student learning difficulties. Nine instructors were able to significantly change their teaching and apply meaningful student seatwork in their lessons. These nine instructors used student seatwork and activities 30 70% of the time, whereas previously 90% of the time involved lectures. Videotape records showed that more than 70% of the students were continuously on task. Four instructors had considerable difficulties in applying the new approach but also had difficulties with conventional lectures. The project constituted the start of a departmental reorientation with a focus on effectiveness of teaching and learning. Subsequently the faculty and course development model developed in this study was used to revise other courses. The theory of Rogan and Grayson proved useful in describing the change processes.

    Information is lacking as to the effect on bond strength of the etching modes of universal adhesives when they are used to bond dual-polymerizing composite resins to dentin. The purpose of this in vitro study was to investigate the bonding of dual-polymerizing foundation composite resins to dentin when universal bonding agents are used in self-etch or etch-and-rinse modes. Sixty caries-free, extracted third molar teeth were sectioned transversely in the apical third of the crown and allocated to 12 groups (n=5). Three different bonding agents (Scotchbond Universal, OptiBond XTR, All-Bond Universal) were used to bond 2 different dual-polymerizing composite resins (CompCore AF or CoreFlo DC) to dentin, using 2 different etching approaches (etch-and-rinse or self-etch). The specimens were sectioned into sticks (1×1×8 mm) with a precision saw. The bond strength of the specimens was tested under microtensile force at a crosshead speed of 0.5 mm/min. The data were analyzed using a 3-way ANOVA, a Games-Howell post hoc comparisons model, and Student t tests with Bonferroni corrections (α=.05). In the overall model, the composite resin used had no effect on bond strength (P=.830). The etching protocol by itself also did not have a significant effect (P=.059), although a trend was present. The bonding agent, however, did have an effect (Pcomposite resins to dentin, no single etching protocol is better than another. Depending on which bonding agent is being used, one etching mode may perform better. Copyright © 2017 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

  11. Effects of university affiliation and "school spirit" on color preferences: Berkeley versus Stanford.

    Science.gov (United States)

    Schloss, Karen B; Poggesi, Rosa M; Palmer, Stephen E

    2011-06-01

    The ecological valence theory (EVT) posits that preference for a color is determined by people's average affective response to everything associated with it (Palmer & Schloss, Proceedings of the National Academy of Sciences, 107, 8877-8882, 2010). The EVT thus implies the existence of sociocultural effects: Color preference should increase with positive feelings (or decrease with negative feelings) toward an institution strongly associated with a color. We tested this prediction by measuring undergraduates' color preferences at two rival universities, Berkeley and Stanford, to determine whether students liked their university's colors better than their rivals did. Students not only preferred their own colors more than their rivals did, but the degree of their preference increased with self-rated positive affect ("school spirit") for their university. These results support the EVT's claim that color preference is caused by learned affective responses to associated objects and institutions, because it is unlikely that students choose their university or develop their degree of school spirit on the basis of preexisting color preferences.

  13. Coupled eco-hydrology and biogeochemistry algorithms enable the simulation of water table depth effects on boreal peatland net CO2 exchange

    2017-12-01

    Water table depth (WTD) effects on net ecosystem CO2 exchange of boreal peatlands are largely mediated by hydrological effects on peat biogeochemistry and the ecophysiology of peatland vegetation. The lack of representation of these effects in carbon models currently limits our predictive capacity for changes in boreal peatland carbon deposits under potential future drier and warmer climates. We examined whether a process-level coupling of a prognostic WTD with (1) oxygen transport, which controls energy yields from microbial and root oxidation-reduction reactions, and (2) vascular and nonvascular plant water relations could explain mechanisms that control variations in net CO2 exchange of a boreal fen under contrasting WTD conditions, i.e., shallow vs. deep WTD. Such coupling of eco-hydrology and biogeochemistry algorithms in a process-based ecosystem model, ecosys, was tested against net ecosystem CO2 exchange measurements in a western Canadian boreal fen peatland over a period of drier-weather-driven gradual WTD drawdown. A May-October WTD drawdown of ˜ 0.25 m from 2004 to 2009 hastened oxygen transport to microbial and root surfaces, enabling greater microbial and root energy yields and peat and litter decomposition, which raised modeled ecosystem respiration (Re) by 0.26 µmol CO2 m-2 s-1 per 0.1 m of WTD drawdown. It also augmented nutrient mineralization, and hence root nutrient availability and uptake, which resulted in improved leaf nutrient (nitrogen) status that facilitated carboxylation and raised modeled vascular gross primary productivity (GPP) and plant growth. The increase in modeled vascular GPP exceeded declines in modeled nonvascular (moss) GPP due to greater shading from increased vascular plant growth and moss drying from near-surface peat desiccation, thereby causing a net increase in modeled growing season GPP by 0.39 µmol CO2 m-2 s-1 per 0.1 m of WTD drawdown. Similar increases in GPP and Re caused no significant WTD effects on modeled

It also augmented nutrient mineralization, and hence root nutrient availability and uptake, which resulted in improved leaf nutrient (nitrogen status that facilitated carboxylation and raised modeled vascular gross primary productivity (GPP and plant growth. The increase in modeled vascular GPP exceeded declines in modeled nonvascular (moss GPP due to greater shading from increased vascular plant growth and moss drying from near-surface peat desiccation, thereby causing a net increase in modeled growing season GPP by 0.39 µmol CO2 m−2 s−1 per 0.1 m of WTD drawdown. Similar increases in

    Purpose This study sought to identify the barriers and enablers to leadership enactment in academic health-care settings. Design/methodology/approach Semi-structured interviews ( n = 77) with programme stakeholders (medical school trainees, university leaders, clinical leaders, medical scientists and directors external to the medical school) were conducted, and the responses content-analysed. Findings Both contextual and individual factors were identified as playing a role in affecting academic health leadership enactment that has an impact on programme development, success and maintenance. Contextual factors included sufficient resources allocated to the programme, opportunities for learners to practise leadership skills, a competent team around the leader once that person is in place, clear expectations for the leader and a culture that fosters open communication. Contextual barriers included highly bureaucratic structures, fear-of-failure and non-trusting cultures and inappropriate performance systems. Programmes were advised to select participants based on self-awareness, strong communication skills and an innovative thinking style. Filling specific knowledge and skill gaps, particularly for those not trained in medical school, was viewed as essential. Ineffective decision-making styles and tendencies to get involved in day-to-day activities were barriers to the development of academic health leaders. Originality/value Programmes designed to develop academic health-care leaders will be most effective if they develop leadership at all levels; ensure that the organisation's culture, structure and processes reinforce positive leadership practices; and recognise the critical role of teams in supporting its leaders.

  16. Cost-effectiveness of universal rotavirus vaccination in reducing rotavirus gastroenteritis in Ireland.

    We evaluated the cost-effectiveness of universal infant rotavirus (RV) vaccination compared to current standard of care of "no vaccination". Two RV vaccines are currently licensed in Ireland: Rotarix and RotaTeq. A cohort model used in several European countries was adapted using Irish epidemiological, resource utilisation and cost data. The base case model considers the impact of Rotarix vaccination on health-related quality of life of children under five years old from a healthcare payer perspective. Other scenarios explored the use of RotaTeq, impact on one caregiver, on societal costs and on cases that do not seek medical attention. Cost was varied between the vaccine list price (€100\\/course) in the base case and an assumed tender price (€70\\/course). One-way and probabilistic sensitivity analyses were conducted. Implementing universal RV vaccination may prevent around 1970 GP visits, 3280 A&E attendances and 2490 hospitalisations. A vaccination programme was estimated to cost approximately €6.54 million per year but €4.65 million of this would be offset by reducing healthcare resource use. The baseline ICER was €112,048\\/QALY and €72,736\\/QALY from the healthcare payer and societal perspective, respectively, falling to €68,896 and €43,916\\/QALY, respectively, if the impact on one caregiver was considered. If the price fell to €70 per course, universal RV vaccination would be cost saving under all scenarios. Results were sensitive to vaccination costs, incidence of RV infection and direct medical costs. Universal RV vaccination would not be cost-effective under base case assumptions. However, it could be cost-effective at a lower vaccine price or from a wider societal perspective.

    The Advanced Concepts Group of Sandia National Laboratories hosted a workshop, ''FOILFest: Community Enabled Security'', on July 18-21, 2005, in Albuquerque, NM. This was a far-reaching look into the future of physical protection consisting of a series of structured brainstorming sessions focused on preventing and foiling attacks on public places and soft targets such as airports, shopping malls, hotels, and public events. These facilities are difficult to protect using traditional security devices since they could easily be pushed out of business through the addition of arduous and expensive security measures. The idea behind this Fest was to explore how the public, which is vital to the function of these institutions, can be leveraged as part of a physical protection system. The workshop considered procedures, space design, and approaches for building community through technology. The workshop explored ways to make the ''good guys'' in public places feel safe and be vigilant while making potential perpetrators of harm feel exposed and convinced that they will not succeed. Participants in the Fest included operators of public places, social scientists, technology experts, representatives of government agencies including DHS and the intelligence community, writers and media experts. Many innovative ideas were explored during the fest with most of the time spent on airports, including consideration of the local airport, the Albuquerque Sunport. Some provocative ideas included: (1) sniffers installed in passage areas like revolving door, escalators, (2) a ''jumbotron'' showing current camera shots in the public space, (3) transparent portal screeners allowing viewing of the screening, (4) a layered open/funnel/open/funnel design where open spaces are used to encourage a sense of ''communitas'' and take advantage of citizen ''sensing'' and funnels are technological

    Full Text Available Positioning of universities on the different educational markets is critical for academic survival, role definition and status clarification on the present education markets. The latter are defined by the globalization of educational services, an increased number of players and their almost fierce competition to attract students and funding. The ever increasing competitiveness all over the world, the new missions that universities have to assume due to pressures from stakeholders, and also from global processes (among which demographics and technology are ever more uncomfortable are important issues that call for a clear organisational communication, as well as for an effective interorganisations information exchange. The present paper explores the importance of identity building for a coherent communication process meant to ensure the adaptability of a Romanian university to the needs of both its Romanian public, and also to those of an international audience. The case study under discussion is The Bucharest Academy of Economic Studies (BAES, its identity, vision and mission and strategies development. The analysis of the identity building process in the BAES starts from the definition of the university as a “research and teaching university which organises higher and scientific preparation in the area of economic and administrative studies”, as approved by the Senate in 2007 (www.ase.ro. As an important dimension of the identity building process refers to its reception by the public involved, a questionnaire was given to a number of staff and students. The findings of this questionnaire, as well as several opinions verbalised during formal and informal meetings and personal conversations are included in this study.

    Slowly strained solids deform via intermittent slips that exhibit a material-independent critical size distribution. Here, by comparing two disparate systems - granular materials and bulk metallic glasses - we show evidence that not only the statistics of slips but also their dynamics are remarkably similar, i.e. independent of the microscopic details of the material. By resolving and comparing the full time evolution of avalanches in bulk metallic glasses and granular materials, we uncover a regime of universal deformation dynamics. We experimentally verify the predicted universal scaling functions for the dynamics of individual avalanches in both systems, and show that both the slip statistics and dynamics are independent of the scale and details of the material structure and interactions, thus settling a long-standing debate as to whether or not the claim of universality includes only the slip statistics or also the slip dynamics. The results imply that the frictional weakening in granular materials and the interplay of damping, weakening and inertial effects in bulk metallic glasses have strikingly similar effects on the slip dynamics. These results are important for transferring experimental results across scales and material structures in a single theory of deformation dynamics.

    The Antarctic Dry Valleys represent a unique environment where it is possible to study dry permafrost overlaying an ice-rich permafrost. In this paper, two opposing mechanisms for ice table stability in University Valley are addressed: i) diffusive recharge via thin seasonal snow deposits and ii) desiccation via salt deposits in the upper soil column. A high-resolution time-marching soil and snow model was constructed and applied to University Valley, driven by meteorological station atmospheric measurements. It was found that periodic thin surficial snow deposits (observed in University Valley) are capable of drastically slowing (if not completely eliminating) the underlying ice table ablation. The effects of NaCl, CaCl2 and perchlorate deposits were then modelled. Unlike the snow cover, however, the presence of salt in the soil surface (but no periodic snow) results in a slight increase in the ice table recession rate, due to the hygroscopic effects of salt sequestering vapour from the ice table below. Near-surface pore ice frequently forms when large amounts of salt are present in the soil due to the suppression of the saturation vapour pressure. Implications for Mars high latitudes are discussed.

    The evolution of dust at redshifts z > or approx. 9, and consequently the dust properties, differs greatly from that in the local universe. In contrast to the local universe, core collapse supernovae (CCSNe) are the only source of thermally-condensed dust. Because of the low initial dust-to-gas mass ratio, grain destruction rates are low, so that CCSNe are net producers of interstellar dust. Galaxies with large initial gas mass or high mass infall rate will therefore have a more rapid net rate of dust production comported to galaxies with lower gas mass, even at the same star formation rate. The dust composition is dominated by silicates, which exhibit a strong rise in the UV opacity near the Lyman break. This "silicate-UV break" may be confused with the Lyman break, resulting in a misidentification of a galaxies' photometric redshift. In this paper we demonstrate these effects by analyzing the spectral energy distribution (SED) of MACS1149-JD, a lensed galaxy at z = 9.6. A potential 2mm counterpart of MACS1149-JD has been identified with GISMO. While additional observations are required to corroborate this identification, we use this possible association to illustrate the physical processes and the observational effects of dust in the very high redshift universe. Subject headings: galaxies: high-redshift - galaxies: evolution - galaxies: individual (MACS1149- JD) - Interstellar medium (ISM), nebulae: dust, extinction - physical data and processes: nuclear reactions, nucleosynthesis, abundances.

    Research on positive emotions associated with the performance of an activity, such as work or study, has increased exponentially in recent years. Passion is understood as an attitude and intense emotion in the performance of an activity, and it has shown both positive and negative consequences for well-being. A link between social identity and positive emotions through social category membership has been described. The aim of this work is to study the relationship between social identity, the dimensions of passion and the positive impact on university responses. A quasi-experimental design was used on a sample of 266 university students from different Spanish universities (Universidad Nacional de Educación a Distancia, Universidad Miguel Hernández and Universidad de Alicante). Descriptive analyzes were performed on the study's variables using SPSS 18. Structural equation modeling was carried out with AMOS 18 and the mediational analysis with MODMED macro developed by Preacher, Rucker, and Hayes (2007). The results show that the identity of the studies had an indirect effect on positive responses mediated by passion for the studies (RMSEA = .07; CFI = .97; NFI = .96; TLI = .92). It is observed that the harmonious and obsessive dimensions of passion differ in the mediating effect on happiness and satisfaction with studies. Practical and theoretical implications for well-being are discussed.

    We clarify the status of transplanckian effects on the cosmic microwave background (CMB) anisotropy. We do so using the boundary effective action formalism of hep-th/0401164 which accounts quantitatively for the cosmological vacuum ambiguity. In this formalism we can clearly 1) delineate the validity of cosmological effective actions in an expanding universe. The corollary of the initial state ambiguity is the existence of an earliest time. The inability of an effective action to describe physics before this time demands that one sets initial conditions on the earliest time hypersurface. A calculation then shows that CMB anisotropy measurements are generically sensitive to high energy corrections to the initial conditions. 2) We compute the one-loop contribution to the stress-tensor due to high-energy physics corrections to an arbitrary cosmological initial state. We find that phenomenological bounds on the backreaction do not lead to strong constraints on the coefficient of the leading boundary irrelevant op...

    The existing literature shows dance to be an innovative and successful form of stress management. Previous research indicates that Biodanza is able to increase well-being and personal resources and prevent stress. However, Biodanza has not yet been empirically tested as a possible therapy for application outside the clinical context in young adults with perceived stress. This study aimed to determine the effectiveness of Biodanza in reducing symptoms of perceived stress and depression and in promoting sleep quality in young adults, comparing the changes with those observed in a control group. Randomized controlled trial. This study was carried out at the Faculty of Health Sciences of the University of Almería. One hundred and twenty-one university students with perceived stress were randomly placed into either a Biodanza group or a wait-list control group. Study participants attended Biodanza sessions for 90 min a week, over a period of 4 weeks. Depression, perceived stress, and sleep quality were assessed both before and after intervention. Ninety-five participants completed the program and were included in the statistical analysis. Significant differences in perceived stress [t (93) = 2.136; p = 0.015] and depression [t (93) = 2.738; p = 0.000] were observed after the Biodanza period. Pre/post analysis found that Biodanza also had a significant effect on depression (Cohen d = 1.88; p stress (Cohen d = 0.79; p stress management strategy for students. The results of this study showed Biodanza to have a positive effect on perceived stress and depression in young adults. This demonstrates how artistic, collaborative, and psychophysical interventions are an effective means of preventing and managing these problems in university students.

    To describe the cost of diarrhoeal illness in children aged 6-24 months in a rural South African community and to determine the threshold prevalence of stunting at which universal Zn plus vitamin A supplementation (VAZ) would be more cost-effective than vitamin A alone (VA) in preventing diarrhoea. We conducted a cost analysis using primary and secondary data sources. Using simulations we examined incremental costs of VAZ relative to VA while varying stunting prevalence. Data on efficacy and societal costs were largely from a South African trial. Secondary data were from local and international published sources. The trial included children aged 6-24 months. The secondary data sources were a South African health economics survey and the WHO-CHOICE (CHOosing Interventions that are Cost Effective) database. In the trial, stunted children supplemented with VAZ had 2·04 episodes (95 % CI 1·37, 3·05) of diarrhoea per child-year compared with 3·92 episodes (95 % CI 3·02, 5·09) in the VA arm. Average cost of illness was $Int 7·80 per episode (10th, 90th centile: $Int 0·28, $Int 15·63), assuming a minimum standard of care (oral rehydration and 14 d of therapeutic Zn). In simulation scenarios universal VAZ had low incremental costs or became cost-saving relative to VA when the prevalence of stunting was close to 20 %. Incremental cost-effectiveness ratios were sensitive to the cost of intervention and coverage levels. This simulation suggests that universal VAZ would be cost-effective at current levels of stunting in parts of South Africa. This requires further validation under actual programmatic conditions.

    Physical activity (PA) promotion among university students is important to contribute to a lifelong healthy lifestyle. Nevertheless, research in the field is still limited in quantity, quality and generalizability. This study aimed at evaluating the effectiveness of two individual-based strategies for promoting PA among university students in such university contexts where course-based interventions are difficult to implement. Thirty-three university students were recruited by means of face-to-face interviews and randomly assigned to three groups. The first group attended individual counselling sessions (based on the Social-Cognitive theory and the Transtheoretical model of behaviour change) via videoconferencing calls, the second used wearable PA monitors designed to motivate to PA, and the third served as control. Interventions lasted 12 weeks. Measures of weekly PA (self-reported by questionnaires and recorded by ActiGraph-GT3X+ monitors) and the stage of change of participants were collected at baseline (t0), immediately after the 12-week intervention (t1), and after a 3-month follow-up (t2). Students in the individual counselling group increased self-reported energy expenditure between t0 and t1 and maintained this improvement at t2; on the contrary, there was no increase in ActiGraph measures of PA. Progression through stages of changes was observed in the same group at t1, followed by some relapses at t2. No significant differences were found neither in the group of students who used the PA monitors nor in the control group. Although measures of self-reported PA and stage of change suggest the effectiveness of the counselling intervention, the results obtained with accelerometers are contrasting, probably due to the fact that some types of PA participants engaged in could not be recorder by accelerometers. Further studies are needed to determine the efficacy of individual counselling to promote PA in university students. The autonomous use of PA monitors had

    To determine whether general cognitive ability, basic mathematic processing, and mathematic attainment are universally affected by gestation at birth, as well as whether mathematic attainment is more strongly associated with cohort-specific factors such as schooling than basic cognitive and mathematical abilities. The Bavarian Longitudinal Study (BLS, 1289 children, 27-41 weeks gestational age [GA]) was used to estimate effects of GA on IQ, basic mathematic processing, and mathematic attainment. These estimations were used to predict IQ, mathematic processing, and mathematic attainment in the EPICure Study (171 children mathematic attainment scores by 2.34 (95% CI: -2.99, -1.70) and 2.76 (95% CI: -3.40, -2.11) points, respectively. There were no differences among children born 34-41 weeks GA. Similarly, for children born mathematic processing scores decreased by 1.77 (95% CI: -2.20, -1.34) points with each lower GA week. The prediction function generated using BLS data accurately predicted the effect of GA on IQ and mathematic processing among EPICure children. However, these children had better attainment than predicted by BLS. Prematurity has adverse effects on basic mathematic processing following birth at all gestations mathematic attainment mathematic processing scores from one cohort to another among children cared for in different eras and countries suggests that universal neurodevelopmental factors may explain the effects of gestation at birth. In contrast, mathematic attainment may be improved by schooling. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

Results from the analysis of covariance revealed that while the score of the full CLEI scale was significantly higher in the intervention group compared with the control (P=0.022, none of the comparisons between the nine CLEI subscales were significantly different between the two groups. For the computer cognitive tasks, the intervention group exhibited significantly better performance in the accuracy of the digital vigilance task (P=0.048, choice reaction time (P=0.004, spatial working memory (P=0.042, and digital vigilance task reaction time (P=0.004. This study showed that a one-semester mindfulness meditation course was able to improve learning effectiveness and both attention and memory aspects of cognitive performance among Taiwanese university students.

    The overarching goal of this study was to ascertain the changes in intraparticle mass transport rates for organic contaminants resulting from nano-enabled hybridization of commercially available granular activated carbon (GAC). Three different nano-enabled hybrid media were fabricated by in-situ synthesizing titanium dioxide nanoparticles inside the pores of GAC sorbent, characterized, and evaluated for removal of two model organic contaminants under realistic conditions to obtain the intraparticle mass transport (pore and surface diffusion) coefficients. The results validated the two hypotheses that: (H1) the pore diffusion rates of organic contaminants linearly decrease with decrease in cumulative pore volume caused by increase in metal (hydr)oxide nanoparticle content inside the pores of the hybrid GAC sorbent; and (H2) introduction of metal (hydr)oxide nanoparticles initially increases surface diffusivity, but additional loading causes its decrease as the increase in metal (hydr)oxide nanoparticles content continues to reduce the porosity of the GAC sorbent. Nano-enabled hybridization of commercially available GAC with metal (hydr)oxides has the potential to significantly increase the intraparticle mass transport limitations for organic contaminants. Introduction of metal (hydr)oxide nanoparticles inside the pores of a pristine sorbent causes the pore diffusion rates of organic contaminants to decrease as the cumulative pore volume is reduced. In contrast, the introduction of limited amounts of metal (hydr)oxide nanoparticles appears to facilitate the surface diffusion rates of these contaminants. Copyright © 2017 Elsevier B.V.

    Full Text Available This study investigates whether the new online registration and admission system implemented at a Tertiary Institution in Gauteng, South Africa, was successful and effective. The Institution under study is the first in South Africa to implement this new online registration system from the 3rd of January 2013 using a system called the Integrated Tertiary Software (ITS Mobile information system. The information system enables students to apply online without physically visiting the institution and provides the status of their registration and admission applications via their smartphones. A total of one hundred 1st year students and ten personnel were sampled to respond to self-completed questionnaires. The efficiency of this new online system was evaluated using the Technology Acceptance Model (TAM, the Web of System Performance (WOSP model and the DeLone and McLean IS Success model as well as the indicators of system ineffectiveness and attributes on the basis of which an information system was evaluated. Key findings emerging from the data analysis and interpretation show that the new online system met the expectations of most staff and students with the exception of few staff members and students. The findings show that the investment made on the new online registration system is benefiting the University and students. The implementation of the new online registration and admission system was a success to a larger extent because the expectations of most users were met. The online system is effective as it was evaluated using the conventional measuring methods and resulted in positive outcomes.

  17. Low-energy effective models for two-flavor quantum chromodynamics and the universality hypothesis

    2014-01-01

    Our thesis is centered around the question of which order the chiral phase transition of two-flavor QCD is. First of all we outline several general aspects of phase transitions which are of central importance for the understanding of the RG approach towards them. Our focus lies on reviewing the universality hypothesis, a crucial ingredient when it comes to the construction of effective theories for order parameters, the credibility of which often heavily depends on universality arguments. We finish the chapter with an attempt to formulate the latter more precisely than usually done. The next chapter discusses the chiral phase transition from a general point of view. We supplement well-known facts with a detailed discussion of the so-called O(4) conjecture. Thereafter we introduce the nonperturbative method we use, the FRG method. Furthermore, we discuss the relation between effective models for QCD and the underlying fundamental theory making use of the FRG perspective. The next chapter is concerned with a mathematical subject indispensable for our approach towards the study of phase transitions, namely the systematic construction of polynomial invariants characterizing a given symmetry. With this thesis we point out its relevance in the context of high-energy physics. We present a simple, but novel, brute-force algorithm to effectively construct invariants of a given polynomial order. The next chapter is devoted to RG studies of several dimensionally reduced theories which are capable to either predict or to rule out the possible existence of a second-order phase transition. Of main interest for us is the linear sigma model, particularly in presence of the axial anomaly. It turns out that the fixed-point structure of the latter is rather complicated, requiring a deeper understanding of the underlying method and its preconditions. This leads us to a careful analysis of the fixed-point structure of several models, which is of great benefit for our review of the

    Full Text Available The main purpose of this study is to investigate the effectiveness of employing Concept Mapping (hereafter CM in vocabulary instruction on Iranian pre-university students. This study also seeks to find whether there is difference between male and female students’ vocabulary learning when they are subjected to CM instruction. In so doing, an Oxford Placement Test was administered among 120 pre-university students in two high schools in Iran.  Eighty    students who scored between +1 and -1 standard deviation above and below the mean were selected and randomly assigned into concept mapping group (CM and non-concept mapping group (NCM (20 male and 20 female. The results indicated that the CM group outperformed the NCM group in vocabulary learning. It was also revealed that there was no significant difference between males and females. Some pedagogical implications in the EFL context are discussed in the subsequent section. Keywords: vocabulary instruction, pre-university students, concept mapping

    Restoration ecologists conduct both basic and applied research using a diversity of funding and collaborative models. Over the last 17 years we have assessed the effectiveness of a stream compensation project in Canada's north, where an independent university-based research program was a condition of the regulatory approval process. This resulted in a non-traditional university-government-industry partnership. Here we share seven lessons that we learned from our collective experiences with the research partnership and use the Ekati diamond mine as a case study to illustrate and support lessons learned. Our advice includes opinions on the importance of: engaging collaborators early, defining roles and responsibilities, data sharing and standardization, the use of natural streams to set restoration targets, expect setbacks and surprises, treating restoration as an opportunity to experiment, and how to define success. Many of the lessons learned are broadly applicable to those whom embark on research collaborations among industry, universities, and consulting companies within a regulatory framework and may be of particular value to collaborators in early stages of their career.

    Indigenous peoples in Australia, New Zealand and Canada carry a greater burden of chronic kidney disease (CKD) than the general populations in each country, and this burden is predicted to increase. Given the human and economic cost of dialysis, understanding how to better manage CKD at earlier stages of disease progression is an important priority for practitioners and policy-makers. A systematic review of mixed evidence was undertaken to examine the evidence relating to the effectivness, cost-effectiveness and acceptability of chronic kidney disease management programs designed for Indigenous people, as well as barriers and enablers of implementation of such programs. Published and unpublished studies reporting quantitative and qualitative data on health sector-led management programs and models of care explicitly designed to manage, slow progression or otherwise improve the lives of Indigenous people with CKD published between 2000 and 2014 were considered for inclusion. Data on clinical effectiveness, ability to self-manage, quality of life, acceptability, cost and cost-benefit, barriers and enablers of implementation were of interest. Quantitative data was summarized in narrative and tabular form and qualitative data was synthesized using the Joanna Briggs Institute meta-aggregation approach. Ten studies were included. Six studies provided evidence of clinical effectiveness of CKD programs designed for Indigenous people, two provided evidence of cost and cost-effectiveness of a CKD program, and two provided qualitative evidence of barriers and enablers of implementation of effective and/or acceptable CKD management programs. Common features of effective and acceptable programs were integration within existing services, nurse-led care, intensive follow-up, provision of culturally-appropriate education, governance structures supporting community ownership, robust clinical systems supporting communication and a central role for Indigenous Health Workers.

    For bonding indirect restorations, some 'universal' adhesives incorporate a silane coupling agent to chemically bond to glass-rich ceramics so that a separate ceramic primer is claimed to be no longer needed. With this work, we investigated the effectiveness/stability of the silane coupling function of the silanecontaining experimentally prepared adhesives and Scotchbond Universal (3MESPE). Experimental adhesives consisted of Scotchbond Universal and the silane-free Clearfil S3 ND Quick (Kuraray Noritake) mixed with Clearfil Porcelain Bond Activator (Kuraray Noritake) and the two adhesives to which γ-methacryloxypropyltrimethoxysilane (γ-MPTS) was added. Shear bond strength was measured onto silica-glass plates; the adhesive formulations were analyzed using fourier transform infrared spectroscopy (FTIR) and 13C nuclear magnetic resonance (NMR). In addition, shear bond strength onto CAD-CAM composite blocks was measured without and after thermo-cycling ageing. A significantly higher bond strength was recorded when Clearfil Porcelain Bond Activator was freshly mixed with the adhesive. Likewise, the experimental adhesives, to which γ-MPTS was added, revealed a significantly higher bond strength, but only when the adhesive was applied immediately after mixing; delayed application resulted in a significantly lower bond strength. FTIR and (13)C NMR revealed hydrolysis and dehydration condensation to progress with the time after γ-MPTS was mixed with the two adhesives. After thermo-cycling, the bond strength onto CAD-CAM composite blocks remained stable only for the two adhesives with which Clearfil Porcelain Bond Activator was mixed. Only the silane coupling effect of freshly prepared silanecontaining adhesives was effective. Clinically, the use of a separate silane primer or silane freshly mixed with the adhesive remains recommended to bond glass-rich ceramics. Copyright © 2016 The Academy of Dental Materials.

    Dimensional analysis of the experimentally observed dependence of the physical properties of nanoparticles, nanofilms and nanomaterials showed that there is a universal equation that accurately describes the observed size effects. It is shown that the size factor is also a universal value and is determined only by the atomic structure of the nanomaterial. Discovered universal relationships enable us to calculate the physical properties (mechanical, electrical, magnetic, thermal, etc.) of small particles and thin films based on knowledge of the properties of bulk materials.

    Schizophrenia remains a priority condition in mental health policy and service development because of its early onset, severity and consequences for affected individuals and households. This paper reports on an 'extended' cost-effectiveness analysis (ECEA) for schizophrenia treatment in India, which seeks to evaluate through a modeling approach not only the costs and health effects of intervention but also the consequences of a policy of universal public finance (UPF) on health and financial outcomes across income quintiles. Using plausible values for input parameters, we conclude that health gains from UPF are concentrated among the poorest, whereas the non-health gains in the form of out-of-pocket private expenditures averted due to UPF are concentrated among the richest income quintiles. Value of insurance is the highest for the poorest quintile and declines with income. Universal public finance can play a crucial role in ameliorating the adverse economic and social consequences of schizophrenia and its treatment in resource-constrained settings where health insurance coverage is generally poor. This paper shows the potential distributional and financial risk protection effects of treating schizophrenia.

    The aim of this study was to evaluate the effectiveness and sustainability of educational interventions to encourage incident reporting. This was a quasi-experimental design. The study involved nurses working in two gastroenterology surgical wards at Fukuoka University Hospital, Japan. The number of participants on each ward was 26 nurses at baseline. For the intervention group, we provided 15 minutes of education about patient safety and the importance of incident reporting once per month for six months. After the completion of the intervention, we compared incident reporting in the subsequent 12 months for both groups. Questionnaires about reasons/motives for reporting were administered three times, before the intervention, after the intervention, and six months after the intervention for both the intervention group and the control group. For the intervention group, incident reporting during the 6 months after the intervention period increased significantly compared with the baseline. During the same period, the reasons and motives for reporting changed significantly in the intervention group. The increase in reported incidents during the 6- to 12-month period following the intervention was not significant. In the control group, there was no significant difference during follow-up compared with the baseline. A brief intervention about patient safety changed the motives for reporting incidents and the frequency of incidents reported by nurses working in surgical wards in a university hospital in Japan. However, the effect of the education decreased after six months following the education. Regular and long-term effort is required to maintain the effect of education.

    A prototype of an asymptotically non-flat black hole spacetime is that of a Schwarzschild black hole in the background of the Einstein universe, which is a special case of the representation of a black hole in a cosmological background given by Vaidya. Recently, this spacetime has been studied in detail by Nayak et al. They constructed a composite spacetime called the Vaidya-Einstein-Schwarzschild (VES) spacetime. We investigate some of the physical effects inherent to this spacetime. We carry out a background-black hole decomposition of the spacetime in order to separate out the effects due to the background spacetime and the black hole. The physical effects we study include the classical tests - the gravitational redshift, perihelion precession and light bending - and circular geodesics. A detailed classification of geodesics, in general, is also given

    This article reports on three pre- versus post-season prospective studies in which male university and high school contact sport players predominantly of Rugby Union (hereafter rugby) were compared with age, education, and IQ equivalent non-contact sport controls on the ImPACT (Immediate Postconcussion Assessment and Cognitive Testing) test. All analyses revealed a relative absence of practice effects on the Visual Motor Speed (VMS) composite for contact sport groups compared with controls. The VMS data for rugby players from each study were pooled and subjected to additional analysis (Rugby, n = 145; Controls, n = 106). Controls revealed significant improvement over the season (p rugby players whose performance remained the same (interaction effect, p = .028). It is apparent that practice effects have diagnostic potential in this context, implicating vulnerability on speeded visuomotor processing in association with participation in rugby. Pointers for further research and concussion management in the individual case are explored.

    Full Text Available This article presents the results of an experimental study investigating the differential effects of two grammar-teaching options on learning tense and grammatical aspect. The treatment conditions were implemented with young adult Algerian EFL learners in two first-semester classes at the university level.The first group was given comprehension practice only. The second group was given both comprehension and production practice.Descriptive statistics indicated that the second group outperformed the first group. However, the statistical analysis (Anova revealed that the instructional effect did not amount to statistically significant learning gains. Pedagogically, the results of the study seem to support the use of output practice as well as input-based practice in the classroom. It is necessary to carry out research on other aspects of language in other similar contexts in order to know which activities of comprehension or production are most effective.

    McCall, Madelon J.

    This research was an attempt to hear the student voice concerning secondary science teacher effectiveness and to share that voice with those who impact the educational process. It was a snapshot of university freshmen biology students' opinions of the qualities of effective secondary science teachers based on their high school science experiences. The purpose of this study was to compile a list of effective secondary science teacher qualities as determined through a purposeful sampling of university second semester biology students and determine the role of the secondary science teacher in promoting interest and achievement in science, as well as the teacher's influence on a students' choice of a science career. The research was a mixed methods design using both quantitative and qualitative data obtained through the use of a 24 question electronic survey. There were 125 participants who provided information concerning their high school science teachers. Respondents provided information concerning the qualities of effective secondary science teachers and influences on the students' present career choice. The quantitative data was used to construct a hierarchy of qualities of effective secondary science teachers, divided into personal, professional, and classroom management qualities. The qualitative data was used to examine individual student responses to questions concerning secondary science teacher effectiveness and student career choice. The results of the research indicated that students highly value teachers who are both passionate about the subject taught and passionate about their students. High school science students prefer teachers who teach science in a way that is both interesting and relevant to the student. It was determined that the greatest influence on a secondary student's career choice came from family members and not from teachers. The secondary teacher's role was to recognize the student's interest in the career and provide encouragement

    Background Over two thirds of women who need contraception in Uganda lack access to modern effective methods. This study was conducted to estimate the potential cost-effectiveness of achieving universal access to modern contraceptives in Uganda by implementing a hypothetical new contraceptive program (NCP) from both societal and governmental (Ministry of Health (MoH)) perspectives. Methodology/Principal Findings A Markov model was developed to compare the NCP to the status quo or current contraceptive program (CCP). The model followed a hypothetical cohort of 15-year old girls over a lifetime horizon. Data were obtained from the Uganda National Demographic and Health Survey and from published and unpublished sources. Costs, life expectancy, disability-adjusted life expectancy, pregnancies, fertility and incremental cost-effectiveness measured as cost per life-year (LY) gained, cost per disability-adjusted life-year (DALY) averted, cost per pregnancy averted and cost per unit of fertility reduction were calculated. Univariate and probabilistic sensitivity analyses were performed to examine the robustness of results. Mean discounted life expectancy and disability-adjusted life expectancy (DALE) were higher under the NCP vs. CCP (28.74 vs. 28.65 years and 27.38 vs. 27.01 respectively). Mean pregnancies and live births per woman were lower under the NCP (9.51 vs. 7.90 and 6.92 vs. 5.79 respectively). Mean lifetime societal costs per woman were lower for the NCP from the societal perspective ($1,949 vs. $1,987) and the MoH perspective ($636 vs. $685). In the incremental analysis, the NCP dominated the CCP, i.e. it was both less costly and more effective. The results were robust to univariate and probabilistic sensitivity analysis. Conclusion/Significance Universal access to modern contraceptives in Uganda appears to be highly cost-effective. Increasing contraceptive coverage should be considered among Uganda's public health priorities. PMID:22363480

    Ellis, Sebastian A. R.; Quevillon, Jérémie; You, Tevong; Zhang, Zhengkang

    2017-08-01

    The Universal One-Loop Effective Action (UOLEA) is a general expression for the effective action obtained by evaluating in a model-independent way the one-loop expansion of a functional path integral. It can be used to match UV theories to their low-energy EFTs more efficiently by avoiding redundant steps in the application of functional methods, simplifying the process of obtaining Wilson coefficients of operators up to dimension six. In addition to loops involving only heavy fields, matching may require the inclusion of loops containing both heavy and light particles. Here we use the recently-developed covariant diagram technique to extend the UOLEA to include heavy-light terms which retain the same universal structure as the previously-derived heavy-only terms. As an example of its application, we integrate out a heavy singlet scalar with a linear coupling to a light doublet Higgs. The extension presented here is a first step towards completing the UOLEA to incorporate all possible structures encountered in a covariant derivative expansion of the one-loop path integral.

    Attributional retraining (AR) has been applied in various professional fields. The application of AR in nursing education is rarely seen. This study explores the effects of AR on university nursing students' writing performance, perceived competence, and the relationship between writing performance and perceived competence using a blended platform of online and face-to-face approaches. A single-group experimental study was used. A total of 187 students participated in this study. The setting was the two-year vocational nursing course in a university. The Scale for Rating Composition Tasks and the Perceived Competence Scale were used before and after the AR intervention. The students' writing performance showed significant improvement after the intervention. AR had effectively influenced the students' perceived competence. The perceived competence of the students interacted with the writing performance improvements after the AR intervention. The AR intervention suggests an alternative teaching approach that can help enhance students' English writing performance as well as perceived competence. The AR programme may be applied in English language teaching and professional courses. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To explore the impact of price manipulation and healthy eating information on intended food choices. Health information was provided to a random half of subjects (vs. information on Saudi agriculture). Each subject chose from the same lunch menu, containing two healthy and two unhealthy entrees, deserts and beverages, on five occasions. Reference case prices were 5, 3 and 2 Saudi Arabian Reals (SARs). Prices of healthy and unhealthy items were manipulated up (taxed) and down (subsidized) by 1 SAR in four menu variations (random order); subjects were given a budget enabling full choice within any menu. The number of healthy food choices were compared with different price combinations, and between information groups. Linear regression modelling explored the effect of relative prices of healthy/unhealthy options and information on number of healthy choices controlling for dietary behaviours and hunger levels. University campus, Saudi Arabia, 2013. 99 women students. In the reference case, 49.5% of choices were for healthy items. When the price of healthy items was reduced, 58.5% of selections were healthy; 57.2% when the price of unhealthy items rose. In regression modelling, reducing the price of healthy items and increasing the price of unhealthy items increased the number of healthy choices by 5% and 6% respectively. Students reporting a less healthy usual diet selected significantly fewer healthy items. Providing healthy eating information was not a significant influence. Price manipulation offers potential for altering behaviours to combat rising youth obesity in Saudi Arabia. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available A computer interface for training university students in reading comprehension of expository-argumentative texts is presented. A text is divided into several sections, for each of which several questions are presented; the reader must select an answer from among various choices and then a feedback screen is presented according to the answer. Two experiments were carried out to test the program’s effectiveness. The first one compared the performance of 50 students in two successive but equivalent lessons. In the second one, the performance of 18 students after four lessons was compared with that of 15 students after a single lesson. There were statistically significant differences in both experiments that support the training effectiveness, although with noticeable variability between participants. The scope and limitations of the program due to the number of lessons and the size of the population sample in the second experiment are discussed in relation to the outcomes.

    Full Text Available Although it is well-known that public-funded research has contributed to economic development, even these days it is not clear how to support this research effectively. Tailoring the proper support system still remains a challenge for the government. Th is is also the case for research support for universities, which are one of the main “engines” of public-funded research. One possible answer is performance-based funding. Th is funding has recently come to be increasingly used by many countries. However, performance-based funding may have several inconveniences. Th is article will analyze the performance-based funding that has already been introduced in the Slovak Republic. Our research outcomes prove the fact that this system has resulted in an increase in publication performance, but at the same time in a higher orientation on quantity instead of quality with several new negative effects.

    Genome-enabled mycology is a rapidly expanding field that is characterized by the pervasive use of genome-scale data and associated computational tools in all aspects of fungal biology. Genome-enabled mycology is integrative and often requires teams of researchers with diverse skills in organismal mycology, bioinformatics and molecular biology. This issue of Mycologia presents the first complete fungal genomes in the history of the journal, reflecting the ongoing transformation of mycology into a genome-enabled science. Here, we consider the prospects for genome-enabled mycology and the technical and social challenges that will need to be overcome to grow the database of complete fungal genomes and enable all fungal biologists to make use of the new data.

    Mental illness stigma refers to negative stereotypes and prejudices about people with mental illness, and is a widespread phenomenon with damaging social, psychological, and economic consequences. Despite considerable policy attention, mental illness stigma does not appear to have declined significantly in recent years. Interpersonal contact with persons with mental illness has been identified as a promising approach to reducing mental illness stigma. This study investigates the effect of contact with mental health treatment users on stigma using an observational research design that is free of self-selection bias. The research design is based on the quasi-experiment in which university students are assigned to live together as roommates. Survey data were collected from first-year undergraduates at two large universities in the United States (N = 1605). Multivariable regressions were used to estimate the effect of assignment to a roommate with a history of mental health treatment on a brief measure of stigmatizing attitudes. Contact with a treatment user caused a modest increase in stigma (standardized effect size = 0.15, p = 0.03). This effect was present among students without a prior treatment history of their own, but not among those with a prior history. The findings indicate that naturalistic contact alone does not necessarily yield a reduction in mental illness stigma. This may help explain why stigma has not declined in societies such as the United States even as treatment use has risen substantially. The findings also highlight the importance of isolating the specific components, beyond contact per se, that are necessary to reduce stigma in contact-based interventions.

    India's High Level Expert Group on Universal Health Coverage in 2011 recommended a universal, public-funded and national health coverage policy. As a plausible forward-looking macroeconomic reform in the health sector, this policy proposal on universal health coverage (UHC) needs to be evaluated for age structure transition effect and fiscal sustainability to strengthen its current design and future implementation. Macroeconomic analyses of the long-term implications of age structure transition and fiscal sustainability on India's proposed UHC policy. A new measure of age-specific UHC is developed by combining the age profile of public and private health consumption expenditure by using the National Transfer Accounts methodology. Different projections of age-specific public health expenditure are calculated over the period 2005-2100 to account for the age structure transition effect. The projections include changes in: (1) levels of the expenditure as gross domestic product grows, (2) levels and shape of the expenditure as gross domestic product grows and expenditure converges to that of developed countries (or convergence scenario) based on the Lee-Carter model of forecasting mortality rates, and (3) levels of the expenditure as India moves toward a UHC policy. Fiscal sustainability under each health expenditure projection is determined by using the measures of generational imbalance and sustainability gap in the Generational Accounting methodology. Public health expenditure is marked by age specificities and the elderly population is costlier to support for their healthcare needs in the future. Given the discount and productivity growth rates, the proposed UHC is not fiscally sustainable under India's current fiscal policies except for the convergence scenario. However, if the income elasticity of public expenditure on social welfare and health expenditure is less than one, fiscal sustainability of the UHC policy is attainable in all scenarios of projected public

    Sleep deprivation is common among university students, and has been associated with poor academic performance and physical dysfunction. However, current literature has a narrow focus in regard to domains tested, this study aimed to investigate the effects of a night of sleep deprivation on cognitive and physical performance in students. A randomized controlled crossover study was carried out with 64 participants [58% male ( n  = 37); 22 ± 4 years old (mean ± SD)]. Participants were randomized into two conditions: normal sleep or one night sleep deprivation. Sleep deprivation was monitored using an online time-stamped questionnaire at 45 min intervals, completed in the participants' homes. The outcomes were cognitive: working memory (Simon game© derivative), executive function (Stroop test); and physical: reaction time (ruler drop testing), lung function (spirometry), rate of perceived exertion, heart rate, and blood pressure during submaximal cardiopulmonary exercise testing. Data were analysed using paired two-tailed T tests and MANOVA. Reaction time and systolic blood pressure post-exercise were significantly increased following sleep deprivation (mean ± SD change: reaction time: 0.15 ± 0.04 s, p  = 0.003; systolic BP: 6 ± 17 mmHg, p  = 0.012). No significant differences were found in other variables. Reaction time and vascular response to exercise were significantly affected by sleep deprivation in university students, whilst other cognitive and cardiopulmonary measures showed no significant changes. These findings indicate that acute sleep deprivation can have an impact on physical but not cognitive ability in young healthy university students. Further research is needed to identify mechanisms of change and the impact of longer term sleep deprivation in this population.

  6. Solar Glitter -- Microsystems Enabled Photovoltaics

    Many products have significantly benefitted from, or been enabled by, the ability to manufacture structures at an ever decreasing length scale. Obvious examples of this include integrated circuits, flat panel displays, micro-scale sensors, and LED lighting. These industries have benefited from length scale effects in terms of improved performance, reduced cost, or new functionality (or a combination of these). In a similar manner, we are working to take advantage of length scale effects that exist within solar photovoltaic (PV) systems. While this is a significant step away from traditional approaches to solar power systems, the benefits in terms of new functionality, improved performance, and reduced cost for solar power are compelling. We are exploring scale effects that result from the size of the solar cells within the system. We have developed unique cells of both crystalline silicon and III-V materials that are very thin (5-20 microns thick) and have very small lateral dimensions (on the order of hundreds of microns across). These cells minimize the amount of expensive semiconductor material required for the system, allow improved cell performance, and provide an expanded design space for both module and system concepts allowing optimized power output and reduced module and balance of system costs. Furthermore, the small size of the cells allows for unique high-efficiency, high-flexibility PV panels and new building-integrated PV options that are currently unavailable. These benefits provide a pathway for PV power to become cost competitive with grid power and allow unique power solutions independent of grid power.

    Full Text Available The aim of the study is to examine how blended learning can be used more effectively for university chemistry courses, based on the perceptions of students. The sample included 179 pre-service science teachers in year one through year four who had taken a university chemistry class. Qualitative data were gathered through open-ended questions and semi-structured interviews. The data were analyzed by using descriptive statistics and thematic content analysis. The results revealed necessary design characteristics for an effective blended chemistry course from students’ point of view regarding content of online instruction, the teaching methods, interface design, use of media and other visual elements, usability, design techniques, and facilitator role. The results showed that instruction should be carefully planned and must be appropriate to student needs and characteristics, the content should not be too long or complicated, content should be prepared by experts in chemistry, include reliable and valid information, designed to promote the learning process by choosing appropriate visual elements and media, be consistent with the learning outcomes, and include evaluation questions. Blended instruction should include various updated and easily accessible technological resources and tools to facilitate learning. The results also revealed that blended learning environment is most suitable for specific topics such as organic chemistry, acids and bases, the structure of atom and matter. Finally, a blended learning component matrix was created and suggested to show the interactions between the categories based on the perceptions of the participants. The results of this study, therefore, suggest important implications for instructors when designing effective blended chemistry courses for pre-service science teachers.

    Full Text Available Blended learning research and practice have been areas of growth for two decades in Canada, with over 95% of Canadian higher education institutions involved in some form of blended learning. Despite strong evidence based research and practice blended learning, for the most part, has remained at sidelined in Canadian universities. The article argues the need for blended learning to situate itself within the timely and crucial Higher Education Reform (HER agenda. By aligning the affordances of blended learning with the components of HER, blended learning can clearly serve as an enabler for HER.

    To determine, through the use of a structural equation model, the relationships that exist between physical activity, body fat, perceived physical ability, and three indicators of psychological well-being, in a sample of Spanish university students. A descriptive cross-sectional study of 639 students 18-29 years of age representative of the universities of Valencia, Spain, during the 2005-2006 term. Physical exercise was rated by taking an inventory of healthy behaviors among students. The following scales were applied: self-perceived physical ability, self-esteem, satisfaction with life, and subjective vitality. Body fat was expressed as the percentage of fat mass (PFM). A theoretical model was devised using six measured variables. The participants' level of physical activity was moderate; they perceived themselves to be physically competent; had high self-esteem; were satisfied with life; and had high vitality. Physical activity was negatively correlated with PFM in men and women alike; and negatively associated with perceived physical ability; while perceived physical ability was positively associated with self-esteem, life satisfaction, and subjective vitality. The effect of physical activity on perceived competence was mediated in part by PFM in men. In women, exercise was directly correlated to PFM, as well as perceived ability, without PFM mediation. Increased physical activity is of great value to public health because, in addition to helping to reduce body fat, it improves psychological well-being and self-image.

    We consider the production of an arbitrary number of colour-singlet particles near partonic threshold, and show that next-to-leading order cross sections for this class of processes have a simple universal form at next-to-leading power (NLP) in the energy of the emitted gluon radiation. Our analysis relies on a recently derived factorisation formula for NLP threshold effects at amplitude level, and therefore applies both if the leading-order process is tree-level and if it is loop-induced. It holds for differential distributions as well. The results can furthermore be seen as applications of recently derived next-to-soft theorems for gauge theory amplitudes. We use our universal expression to re-derive known results for the production of up to three Higgs bosons at NLO in the large top mass limit, and for the hadro-production of a pair of electroweak gauge bosons. Finally, we present new analytic results for Higgs boson pair production at NLO and NLP, with exact top-mass dependence.

    Evaluating changes in teaching adopted by teachers after participating in the Pedagogical Health Science Formation extension course taught by the National University of Colombia's Pedagogical Support and Teaching Formation Group from the Medicine Faculty. This was a part-time course; it dealt with topics such as didactics, curriculum, evaluation and the teacher's role. A qualitative, exploratory study was carried out, involving a personal interview formulated by the investigators; this was held in each participant's place of work. Fifty teachers who had taken the course between 2003 and 2004 were interviewed. The questionnaire consisted of ten semi-structured questions. After taking the course, 82 % of the participants considered that the quality of their communication with students was one of their most valued qualities, having understood that learning is a process which must be shared by both teachers and students. 64 % of the participants stated that they had acquired new concepts about evaluation and had increased their use of more participative pedagogical strategies. Teaching training courses had a positive effect on teaching, reflected in the quality of communication, teacher-student relationships and the pedagogic strategies used, all being very important elements in constructivist-orientated pedagogical models. The study's results agreed with other investigators' prior experience. The university must encourage this kind of intervention which will promote its own academic development by improving its teachers' performance.

Methods.  The reference group (RG consisted of 20 students (5 male and 15 female, the test group (TG — 26 (5 male and 19 female. The RG students did fitness during their physical training classes at the university, while the TG students, besides the same program, did Tabata training in class and independently on their own at three levels of intensity four times a week for four weeks. We evaluated the effectiveness by the changes in students’ physical performance. We used χ2 tests (binary variables to compare the output characteristics in the groups, t–tests (continuous variables and Mann-Whitney test to compare the distribution of ordinal variables, and Wilcoxon test (related samples. Results. During the month of the forming experiment being conducted, the TG students’ physical performance showed the increase of + 38.9% and was reliably different from the results of the initial period (p < 0.05. The anthropometric indicators did not significantly change in their dynamics, nor was there any difference between the comparison groups. The evaluation of the effectiveness of interval training by the Tabata methods pursuant to the dynamics of the students’ physical performance allowed to objectively prove the positive effect that additional independent training of students has when implemented.

The aim of this study was to analyze the effectiveness of the meetings held in Tabriz University of Medical Sciences from personnel’s perspective in management setting. Material and Methods : This is a cross-sectional, descriptive study. The study community consisted of 207 managers in different directorship positions in which 82 of them were selected as the sample by using Kookran formula. Data were collected using researcher-made which its validity and reliability were achieved according to Likert spectrum. Data were analyzed by SPSS software version 16. The applied tests included independent T test and Anova. Results : Personnel dedicated 75% of total score for pre meeting processes and meeting management and 32% for the effectiveness of the meetings in the process of achieving the goals, satisfaction from holding the meetings and effective participation in the meetings. In other words, they were compliant with the quality of the meetings but disagreed on the effectiveness of the meetings. Also, these findings showed meaningful relationship between effectiveness and quality of the meetings with age and educational courses. However, there was no meaningful difference between effectiveness and quality of the meetings with gender, level of education and field of study (p>0.05. Conclusion : In order to improve the quality and effectiveness of the meetings, it is necessary to hold meetings’ invitation, beginning and finishing on-time. In addition, participants should be focused and informed about the subjects of the meeting. Furthermore, empowering managers and personnel in different management positions by holding educational packages and workshops is suggested.

    2000-01-01

    We consider lepton-antilepton annihilation into a fermion-antifermion pair at variable c.m. energy. We propose for this process a simple parametrization of the virtual effects of the most general model of new physics of that uses the experimental results of LEP1, SLC as theoretical input. It introduces \\underline{three} functions whose energy dependence is argued to be smooth and, in first approximation, negligible. A couple of representative models of new physics are considered, as a support of the previous claim. Explicit bounds are then derived for this type of new physics from the available LEP2 data, and a discussion is given of the relevance in this respect of the different experimental measurements. The method is then extended to treat the case of two particularly simple models of {\\it non universal} type, for which it is possible to draw analogous conclusions.

    Lapkin, Samuel; Levett-Jones, Tracy; Gilligan, Conor

    2011-01-01

    Background: A key responsibility of universities is to prepare health professional graduates for their roles as effective members of the health care team. Currently, most university-based health professional education is delivered in a traditional, discipline specific way. This approach is limited in its ability to equip graduates with the necessary knowledge, skills and attitudes for effective interprofessional collaboration and for working as part of a complex health care team. Interprofessional education occurs when learners from two or more professional groups learn about, from and with each other. The fundamental premise of interprofessional education is that if health professional students learn together they will be better prepared for interprofessional collaboration ultimately leading to improved patient outcomes.Objective -The objective of this systematic review was to identify the best available evidence for the effectiveness of university-based interprofessional education.Inclusion criteria -The review included all randomised controlled trials and quasi-experimental studies that assessed the effectiveness of interprofessional education in university-based health professional programs. All studies that included two or more undergraduate or post-graduate health professional groups engaged in interprofessional education were considered. Outcome measures included objectively measured or self-reported educational outcomes and/or professional competencies related to interprofessional education as assessed by validated instruments such as the Readiness for Interprofessional Learning Scale and the Interdisciplinary Education Perception Scale. A three-stage comprehensive search strategy was utilised to search across ten electronic databases. English language studies published between January 2000 and February 2011 were considered for inclusion.Methodological quality: Two independent reviewers assessed the methodological quality of each study selected for

    The authors investigated the effects of a brief video intervention on the racial attitudes of White university students. One hundred thirty-eight self-identified White students were randomly assigned to either an experimental condition in which they viewed a video documenting the pervasiveness of institutional racism and White privilege in the United States or a neutral control condition. Findings offer preliminary support that participants in the experimental, but not the control, condition showed significant increases in racial awareness (i.e., decrease in racial color-blindness), White empathy, and White guilt, at posttest. However, no significant differences in racial prejudice or White fear of racial minorities were observed at posttest. Implications for multicultural counseling training, diversity programming, and future research are discussed.

    The electrodynamics of topological insulators (TIs) is described by modified Maxwell's equations, which contain additional terms that couple an electric field to a magnetization and a magnetic field to a polarization of the medium, such that the coupling coefficient is quantized in odd multiples of α/4π per surface. Here we report on the observation of this so-called topological magnetoelectric effect. We use monochromatic terahertz (THz) spectroscopy of TI structures equipped with a semitransparent gate to selectively address surface states. In high external magnetic fields, we observe a universal Faraday rotation angle equal to the fine structure constant α=e2/2hc (in SI units) when a linearly polarized THz radiation of a certain frequency passes through the two surfaces of a strained HgTe 3D TI. These experiments give insight into axion electrodynamics of TIs and may potentially be used for a metrological definition of the three basic physical constants. PMID:28504268

    This study compared the effects of an HPV education program by gender among Korean university students in terms of their knowledge of HPV, intention to prevent HPV, awareness of sexual rights, and perception of gender equality. A quasi-experimental pre-post design was employed. 31 male and 28 female university students participated in eight sessions of an HPV prevention program for four weeks and in a self-administrative survey. At pre-test, the perception of gender equality and some of the intentions to prevent HPV, including the intention to make regular use of condoms, reduce the number of sexual partners, abstain from sex until marriage, and stop smoking or stay non-smoker, were lower among men than women. When these differences by gender at pre-test were taken into account using ANCOVA, education outcome measures at post-test did not differ by gender. After completing the HPV prevention program, both male and female students presented a significant increase in terms of HPV knowledge, awareness of sexual rights, and perception of gender equality. Among the intentions to prevent HPV, only male intention to recommend the Pap test to their partner and female intention to regularly seek the Pap test and pelvic examinations were significantly increased after the program. The HPV program was effective for both genders eliminating gender differences in attitudes and prevention intentions of HPV. However, the intentions to prevent HPV did not increase significantly, and future research is warranted to better understand students' perceived obstacles for practicing HPV prevention methods.

    Full Text Available Teaching language as a second or foreign language, undoubtedly, is so demanding and seeking to find methods for facilitating this prominent practice whets the appetite of any practitioner who works in this field. Research shows that using drama in the classroom as a means of teaching helps students learn socially, academically, and developmentally. This study was an attempt to determine the effect of dramatized instruction on the speaking ability of EFL learners of Imam Ali University. Sixty EFL male students at the intermediate level participated in the study. Their age range was 19-22. Two instruments were utilized in this study; pretest, and posttest.  The data were analyzed through t-test. The data analysis indicated that the mean scores of the experimental group students (M = 72.80 were significantly different (3.29>2; df = 58 from the control group students (M = 65.39. In other words, the experimental group outperformed the control group in the posttest significantly. Moreover, the findings indicated that dramatized instruction does have a great effect on the speaking skills. This study supported the idea of effectiveness of dramatized instruction on developing speaking skill and the teachers can help the learners at lower levels promote their speaking skill through dramatized instruction in EFL classes.

    Transmission electron microscope (TEM) interfaced to one or more ion implanters and/or accelerators, i.e. in situ TEM, provides effective tools to observe microstructural changes of studied samples during the ion irradiation. Evolution of both radiation damages and irradiation-induced nano-sized microstructures can be investigated with this technique, much more convenient than conventional ex situ techniques. In situ TEM technique has been widely applied in various fields, especially in the study of radiation damages of structural materials of fission and fusion nuclear reactors, and in evaluation and qualification of radioactive waste forms. Nowadays there are more than a dozen such facilities located in Japan, France, and the United States. Recently, we have constructed the first TEM-Tandem/Implanter interface facility of China in Wuhan University. A modified Hitachi H800 TEM was interfaced to a 200 kV ion implanter and a 2 x 1.7 MV tandem accelerator. Effective steps were taken to isolate the TEM from mechanical vibration from the ion beam line, and no obvious wobbling of the TEM image was observed during the ion implantation. The amorphization process of Si crystal irradiated by 115 keV N + ion beam was observed in the primary experiments, demonstrating that this interface facility is capable of in situ study of radiation effects. An online low energy gaseous ion source which may provide 1-20 keV H + and He + is under construction. (authors)

    In the United Arab Emirates (UAE) tobacco use is rampant. A less reported, yet widely used form of smoking native to UAE is midwakh or dhokha. The aim of the study is to assess the acute effects of smoking dokha (Arabian pipe) on the cardiovascular and respiratory systems among male university students in the UAE. A quasi-experimental study was conducted among 97 male volunteers aged more than 17 years. Blood pressure, heart rate and respiratory rate of each participant, were measured before and immediately after smoking. A self administered questionnaire was used to collect personal details and data about smoking pattern. Mean increases in systolic blood pressures (12±1 mmHg), heart rates (20±2 bpm) and respiratory rates (4±1 breaths/min) were observed (pSmoking dokha has a significant acute effect on systolic blood pressure, heart rate and respiratory rate. Anti smoking campaigns must address the ill effects of this form of smoking. Results from the study warrant further research into this method of smoking which is becoming more popular.

    Approximately, 40-70% of active pharmaceutical ingredients (API) are severely limited by their extremely poor aqueous solubility, and consequently, there is a high demand for excipients that can be used to formulate clinically relevant doses of these drug candidates. Here, proof-of-concept studies demonstrate the potential of our recently discovered acyclic cucurbit[n]uril-type molecular container Motor1 (M1) as a solubilizing agent for insoluble drugs. M1 did not induce significant rates of mutations in various Salmonella typhimurium test strains during the Ames test, suggesting low genotoxicity. M1 also has low risk of causing cardiac toxicity in humans since it did not inhibit the human Ether-à-go-go-Related Gene channel as tested on transfected CHO cell lines via patch clamp analysis. Albendazole (ABZ) is a widely used antihelminthic agent but that has also shown promising efficacy against cancerous cells in vitro. However, due to its low aqueous solubility (2.7 μM) and poor pharmacokinetics, ABZ is clinically limited as an anticancer agent. Here we investigated the potential of M1 as a solubilizing excipient for ABZ formulation. A pharmacokinetic study indicated that ABZ escapes the peritoneal cavity resulting in 78% absolute bioavailability, while its active intermediate metabolite, albendazole sulfoxide, achieved 43% absolute bioavailability. The daily dosing of 681 mg/kg M1 complexed with 3.2 mg/kg of ABZ for 14 days did not result in significant weight loss or pathology in Swiss Webster mice. In vivo efficacy studies using this M1·ABZ inclusion complex showed significant decreases in tumor growth rates and increases in survival of mice bearing SK-OV-3 xenograft tumors. In conclusion, we provide substantial new evidence demonstrating that M1 is a safe and efficient excipient that enables in vivo parenteral delivery of poorly water-soluble APIs.

    Individualized medicine is the healthcare strategy that rebukes the idiomatic dogma of ‘losing sight of the forest for the trees’. We are entering a new era of healthcare where it is no longer acceptable to develop and market a drug that is effective for only 80% of the patient population. The emergence of “-omic” technologies (e.g. genomics, transcriptomics, proteomics, metabolomics) and advances in systems biology are magnifying the deficiencies of standardized therapy, which often provide little treatment latitude for accommodating patient physiologic idiosyncrasies. A personalized approach to medicine is not a novel concept. Ever since the scientific community began unraveling the mysteries of the genome, the promise of discarding generic treatment regimens in favor of patient-specific therapies became more feasible and realistic. One of the major scientific impediments of this movement towards personalized medicine has been the need for technological enablement. Nanotechnology is projected to play a critical role in patient-specific therapy; however, this transition will depend heavily upon the evolutionary development of a systems biology approach to clinical medicine based upon “-omic” technology analysis and integration. This manuscript provides a forward looking assessment of the promise of nanomedicine as it pertains to individualized medicine and establishes a technology “snapshot” of the current state of nano-based products over a vast array of clinical indications and range of patient specificity. Other issues such as market driven hurdles and regulatory compliance reform are anticipated to “self-correct” in accordance to scientific advancement and healthcare demand. These peripheral, non-scientific concerns are not addressed at length in this manuscript; however they do exist, and their impact to the paradigm shifting healthcare transformation towards individualized medicine will be critical for its success.

    The effect of lean process improvement on an inpatient university hospital pharmacy was evaluated. The University of Minnesota Medical Center (UMMC), Fairview, implemented lean techniques in its inpatient pharmacy to improve workflow, reduce waste, and achieve substantial cost savings. The sterile products area (SPA) and the inventory area were prospectively identified as locations for improvement due to their potential to realize cost savings. Process-improvement goals for the SPA included the reduction of missing doses, errors, and patient-specific waste by 30%, 50%, and 30%, respectively, and the reallocation of two technician full-time equivalents (FTEs). Reductions in pharmaceutical inventory and returns due to outdating were also anticipated. Work-flow in the SPA was improved through the creation of accountability, standard work, and movement toward one-piece flow. Increasing the number of i.v. batches decreased pharmaceutical waste by 40%. Through SPA environment improvements and enhanced workload sharing, two FTE technicians from the SPA were redistributed within the department. SPA waste reduction yielded an annual saving of $275,500. Quality and safety were also improved, as measured by reductions in missing doses, expired products, and production errors. In the inventory area, visual control was improved through the use of a double-bin system, the number of outdated drugs decreased by 20%, and medication inventory was reduced by $50,000. Lean methodology was successfully implemented in the SPA and inventory area at the UMMC, Fairview, inpatient pharmacy. Benefits of this process included an estimated annual cost saving of $289,256 due to waste reduction, improvements in workflow, and decreased staffing requirements.

    We investigated the effect of social networking (SN) on academic achievement of dental students at Jazan University, Saudi Arabia. A self-administered questionnaire was distributed during the 2015/16 academic year to all dental students and data were analysed by SPSS version 21. There were 348 participants (70% response rate) and 53% were male. Fifty-one percent of participants reported that they studied just before examinations, and 51% scored 3.5-4.5 Grade Point Average (GPA) in the last semester. Up to 98% of the participants reported using their smartphones/ computers for SN, with 93% doing so on a daily basis, and 66% reported SN during lectures, laboratories and clinics. Fifty-seven percent thought that SN affected their study negatively, and 65% thought that their GPA would improve if they stopped or reduced SN. Students who spent more hours each day on SN had lower GPA scores. SN negatively affected the academic achievement of dental students. Further evaluation and tailored educational programmes are needed to increase students' awareness about the negative effects of SN.

    Rosario-Josefa Marrero

    Full Text Available The aim of this study was to design and implement a positive intervention combined with cognitive-behavioral therapy to enhance subjective and psychological well-being and other positive functioning constructs in a convenience sample. Participants analysed were 48 university students (mean age 22.25, 25 assigned nonrandomized to intervention condition and 23 to no-treatment waiting-list control condition. All participants were assessed pre- and post-intervention to test the treatment program effectiveness. Repeated-measures ANCOVAs, controlling baseline differences between the two groups, indicated that the intervention group reported greater social support after the intervention period than the waiting-list control group. Within-group differences were found for happiness, selfacceptance, positive relations with others, optimism, and self-esteem in the intervention group; these differences did not appear in the waiting-list control group. These findings suggest the limited capacity of this intervention program for improving well-being through positive activities combined with cognitive-behavioral therapy. Future research should analyse what kind of activities could be more effective in promoting well-being depending on the characteristics of participants.

  6. Effects of baryons on the statistical properties of large scale structure of the Universe

    Guillet, T.

    2010-01-01

    Observations of weak gravitational lensing will provide strong constraints on the cosmic expansion history and the growth rate of large scale structure, yielding clues to the properties and nature of dark energy. Their interpretation is impacted by baryonic physics, which are expected to modify the total matter distribution at small scales. My work has focused on determining and modeling the impact of baryons on the statistics of the large scale matter distribution in the Universe. Using numerical simulations, I have extracted the effect of baryons on the power spectrum, variance and skewness of the total density field as predicted by these simulations. I have shown that a model based on the halo model construction, featuring a concentrated central component to account for cool condensed baryons, is able to reproduce accurately, and down to very small scales, the measured amplifications of both the variance and skewness of the density field. Because of well-known issues with baryons in current cosmological simulations, I have extended the central component model to rely on as many observation-based ingredients as possible. As an application, I have studied the effect of baryons on the predictions of the upcoming Euclid weak lensing survey. During the course of this work, I have also worked at developing and extending the RAMSES code, in particular by developing a parallel self-gravity solver, which offers significant performance gains, in particular for the simulation of some astrophysical setups such as isolated galaxy or cluster simulations.

    Globally, the cost-effectiveness of spinal surgery is becoming increasingly important. However, these data are limited to a few countries. The purpose of our study was to examine the cost/quality adjusted life year (cost/QALY) gained for posterior lumbar interbody fusion (PLIF) in the Japanese universal health insurance system. Fifty five patients underwent PLIF for lumbar degenerative spinal canal stenosis between July 2013 and September 2015 was included. Effectiveness was measured using Euro QOL 5-dimension (EQ-5D), Short-Form 8 physical component summary (PCS), and visual analog scale (VAS). The cost was calculated from the perspective of the public healthcare payer. Effectiveness and cost were measured one year after surgery. QALYs were calculated by multiplying the utility value (EQ-5D) and life years. Only direct costs were included on the basis of actual reimbursements. Cost/QALY at a 5-year time horizon with a 2% discount rate was estimated. Sensitivity analysis was performed by varying the time horizon (2 years or 10 years). The exchange rate was defined as US $1 to Japanese 100 yen. Mean total cost one year after surgery was ¥2,802,900 ($28029). Operative cost was ¥1,779,700 ($17797). Mean gained score was 0.22 in EQ-5D, 10.3 in PCS, and -44 in VAS. Cost/QALY was ¥2,697,500 ($26975). Sensitivity analysis demonstrated that cost/QALY at a 10-year time horizon was ¥1,428,300 ($14283) and that cost/QALY at a 2-year time horizon was ¥6,435,400 ($64354). Clinical outcomes after PLIF improved beyond minimum clinical improvement difference. Cost/QALY was below the widely-accepted benchmark (cost/QALY < $50000). PLIF could be regarded as cost-effective interventions. Copyright © 2017 The Japanese Orthopaedic Association. Published by Elsevier B.V. All rights reserved.

    Full Text Available Biocrust moss is an essential soil surface bio-cover. It can represent the latest succession stage among the diverse range of surface-dwelling cryptogams (e.g., cyanobacteria, green algae, and lichen, which are also referred to as biocrusts, and it can make a major contribution to soil stability and fertility in many arid sandy desert ecosystems. The soil surface represents a very large ecological niche that is poikilohydric in nature. Biocrust moss is therefore highly susceptible to drought and sand burial, which are two ubiquitous stressors in arid sandy deserts. However, little information is available regarding the mechanism by which biocrust moss can survive and flourish in these habitats when stressed simultaneously by the two stressors. The combined effects of drought and sand burial were evaluated in a field experiment using the predominant biocrust moss, Bryum argenteum Hedw., in the Tengger Desert, China. Drought was simulated by applying distilled water in three artificial rainfall regimes at 8-day intervals in spring and autumn: 4 and 6 mm (average rainfall, control, 2 and 3 mm (double drought, and 1 and 1.5 mm (4-fold drought, respectively. The effect of sand burial was determined by applying six treatments, i.e., sand depths of 0 (control, 0.5, 1, 2, 4, and 10 mm. The four parameters of chlorophyll a content, PSII photochemical efficiency, regeneration potential, and shoot upgrowth were evaluated in the moss. It was found that the combined effects of drought and sand burial did not exacerbate the single negative effects of the four parameters tested. Drought significantly ameliorated the negative effects of deep-sand burial on the retention of chlorophyll a content, PSII photochemical efficiency, and the regeneration potential of B. argenteum. Sand burial diminished and even reversed the negative effects of drought on the maintenance of chlorophyll a content, PSII photochemical efficiency, and regeneration potential

The combined effects of drought and sand burial were evaluated in a field experiment using the predominant biocrust moss, Bryum argenteum Hedw., in the Tengger Desert, China. Drought was simulated by applying distilled water in three artificial rainfall regimes at 8-day intervals in spring and autumn: 4 and 6 mm (average rainfall, control), 2 and 3 mm (double drought), and 1 and 1.5 mm (4-fold drought), respectively. The effect of sand burial was determined by applying six treatments, i.e., sand depths of 0 (control), 0.5, 1, 2, 4, and 10 mm. The four parameters of chlorophyll a content, PSII photochemical efficiency, regeneration potential, and shoot upgrowth were evaluated in the moss. It was found that the combined effects of drought and sand burial did not exacerbate the single negative effects of the four parameters tested. Drought significantly ameliorated the negative effects of deep-sand burial on the retention of chlorophyll a content, PSII photochemical efficiency, and the regeneration potential of B. argenteum. Sand burial diminished and even reversed the negative effects of drought on the maintenance of chlorophyll a content, PSII photochemical efficiency, and regeneration potential. Although drought and sand

    This study investigated the effect of rubbing force magnitude on dentin bond strengths of multi-mode adhesives applied in self-etch mode. Seventy-two extracted human molar teeth were used. Two different universal adhesives Single Bond Universal (SB) and Clearfil Universal (CL) were applied onto dentin surfaces in three different modes: without rubbing (NR), rubbing with 40 gf (gram-force) (40) or 80 gf (80) load. Teeth were restored with a resin composite. Half of the specimens were subject to thermal aging (10,000 cycles). Microtensile bond strength was measured and data were statistically analyzed with two-way analysis of variance and Tukey's test (α=0.05). Baseline bond strength values for CL adhesive were improved by rubbing (40 and 80 gf) as compared to no rubbing (p0.05). Rubbing improves bonding performance of some universal adhesives to dentin when applied in self-etch mode.

    Full Text Available Objectives : The course "Health IV" and "consulting room" are two resources of learning about the method of preparing proposal and passing the final thesis for medical students at Zahedan University of Medical Sciences (ZUMS. The purpose of this study was to investigate the students' viewpoints on the effects of "Health IV" and consulting room on their final theses (pl. of thesis. Methods : The sample in this descriptive study included 155 medical students of ZUMS who had registered their theses at the school. The study was conducted during 2005-2006 and the data were collected using a questionnaire and analyzed via descriptive statistics of correlation and Chi-square test. Results : The findings of the study revealed that 38.1% of the students agreed or completely agreed with integrating the two courses "Research Methods" and "Health IV". Also, 43.9% of the subjects disagreed or completely disagreed with it. Approximately, 35% of the students used the services of the consulting room in writing their proposals. The effect of this service on the final thesis was low and very low in 10.3%, moderate in 12.3%, and high and very high in 20% of the students. About 25.8% of the subjects used the room services in conducting their theses, 61.3% did not use the services. The percent of the students who used the room in writing the proposal or doing their theses or did not use it at all was 85%. The effect of the room on conducting the thesis project was low and very low in 7.1%, moderate in 11.6%, and high and very high in 20%. Conclusion : The high amount of agreement with the complete integration of the "Research Methods" and "Health IV" needs more investigation. Also, the necessity of the consulting room should be revised by the manager and its continuation should be on the students' demands.

    Gene editing can be used to overcome allo-recognition, which otherwise limits allogeneic T cell therapies. Initial proof-of-concept applications have included generation of such "universal" T cells expressing chimeric antigen receptors (CARs) against CD19 target antigens combined with transient expression of DNA-targeting nucleases to disrupt the T cell receptor alpha constant chain (TRAC). Although relatively efficient, transgene expression and editing effects were unlinked, yields variable, and resulting T cell populations heterogeneous, complicating dosing strategies. We describe a self-inactivating lentiviral "terminal" vector platform coupling CAR expression with CRISPR/Cas9 effects through incorporation of an sgRNA element into the ΔU3 3' long terminal repeat (LTR). Following reverse transcription and duplication of the hybrid ΔU3-sgRNA, delivery of Cas9 mRNA resulted in targeted TRAC locus cleavage and allowed the enrichment of highly homogeneous (>96%) CAR + (>99%) TCR - populations by automated magnetic separation. Molecular analyses, including NGS, WGS, and Digenome-seq, verified on-target specificity with no evidence of predicted off-target events. Robust anti-leukemic effects were demonstrated in humanized immunodeficient mice and were sustained longer than by conventional CAR + TCR + T cells. Terminal-TRAC (TT) CAR T cells offer the possibility of a pre-manufactured, non-HLA-matched CAR cell therapy and will be evaluated in phase 1 trials against B cell malignancies shortly.

    There are safety concerns about energy drinks alongside marketing claims of physiological and behavioural benefits. There is no scientific data about usage of energy drinks in Saudi Arabia. This study determined consumption patterns of energy drinks as well as perceived benefits and side effects amongst students at a Saudi university. This study was carried out in students of University of Dammam from October to December 2010. A questionnaire about energy drink use, reasons for use, benefits and side effects experienced was distributed amongst the university students. Frequencies of responses and differences between male and female students were analysed. A total of 412 students (282 males and 130 females) responded, out of whom 54.60% males and 26.15% female students were energy drink users. Mean age at first use was significantly (pcompany of friends, to keep awake, for more energy and for better performance in driving, sports or exams. Amongst many the commonest (p<0.05) benefit reported was ability to stay awake longer. The students reported a number of adverse effects. Increased urination and insomnia were the commonest in males and females respectively. Only 36.70% males and 14.28% females never experienced an adverse effect. A significant proportion of students at university of Dammam use energy drinks, they have reported a number of effects (perceived as benefits) along with a variety of adverse effects.

    Universal public finance (UPF)-government financing of an intervention irrespective of who is receiving it-for a health intervention entails consequences in multiple domains. First, UPF increases intervention uptake and hence the extent of consequent health gains. Second, UPF generates financial consequences including the crowding out of private expenditures. Finally, UPF provides insurance either by covering catastrophic expenditures, which would otherwise throw households into poverty or by preventing diseases that cause them. This paper develops a method-extended cost-effectiveness analysis (ECEA)-for evaluating the consequences of UPF in each of these domains. It then illustrates ECEA with an evaluation of UPF for tuberculosis treatment in India. Using plausible values for key parameters, our base case ECEA concludes that the health gains and insurance value of UPF would accrue primarily to the poor. Reductions in out-of-pocket expenditures are more uniformly distributed across income quintiles. A variant on our base case suggests that lowering costs of borrowing for the poor could potentially achieve some of the health gains of UPF, but at the cost of leaving the poor more deeply in debt. © 2014 The Authors.

    Two of the problems that currently affect a large proportion of university students are high levels of anxiety and stress experienced in different situations, which are particularly high during the first years of their degree and during exam periods. The present study aims to investigate whether mindfulness training can bring about significant changes in the manifestations of depression, anxiety, and stress of students when compared to another group undergoing a physical activity program and a control group. The sample consisted of 125 students from the Bachelor of Education Program. The measuring instrument used was the Abbreviated Scale of Depression, Anxiety and Stress (DASS-21). The results indicate that the effects of reducing the identified variables were higher for the mindfulness group than for the physical education group and for the control group F(2) = 5.91, p = .004, η2 = .106. The total scores for all variables related to the mindfulness group decreased significantly, including an important stress reduction t(29) = 2.95, p = .006, d = .667. Mindfulness exercises and some individual relaxing exercises involving Physical Education could help to reduce manifestations of stress and anxiety caused by exams in students.

    Relative biological effectiveness (RBE) of proton beams dedicated to radiotherapy was examined using a method of simultaneous irradiation. Mice received i.v. transplantation of syngeneic fibrosarcoma (NFSa) cells. These mice were divided into 3 groups on the following day, and thorax was simultaneously irradiated with one of the following beams: 70MeV proton beam at National Institute of Radiological Sciences (NIRS), 250 MeV Proton beam at Tsukuba University (PARMS) and 60 Co γ ray. Ten to 13 days thereafter, lungs were removed for colony counts to give dose-cell survival relationships. RBE of NIRS proton was ranging from 1.01 to 1.12 with an average of 1.06 while that of PARMS proton was ranging from 1.03 to 1.09 with an average of 1.06 at surviving fraction of 0.01. The simultaneous irradiation for RBE study was found to be reliable at large dose-low survival regions. (author)

    In large hospitals, collaborative clinical practice is currently emphasized, with members of various departments expected to work as a team. The importance of accurate communication among the team members is of utmost importance. To improve such communication, the introduction of mobile voice communication systems has received much attention in Japan. Shimane University Hospital also introduced a Personal Handy-phone System (PHS) for doctors. In the traditional setting, much time was wasted searching for doctors through multiple calls on fixed-line telephones. In order to measure the effectiveness of our system, the change in the number of calls made on fixed-line telephones before and after PHS installation was compared. The total number of calls was reduced by more than 35%, and the number of calls to the wards on weekdays was reduced by half. Mobile telecommunication systems with small output power, such as PHS, are known to cause little interference with medical devices which makes it possible to use mobile voice communication safely in hospitals. The improvement in communication by this systems resulted in an improvement in labor efficiency.

    The purpose of this study was to identify the factors that influence the shopping attitudes of college students with and without ADHD. This study also examined the effects of ADHD on the academic and social lives of college students. The sample consisted of 219 university students. These students were interviewed by a psychiatrist with regard to ADHD symptoms according to the DSM-IV. The Adult ADHD Self Report Scale (ASRS), the Teen Interpersonal Influence Scale, and a demographic information form were used as measurement devices. The ADHD and control groups were classified in three different ways: (1) met the ADHD criteria for both Clinical Diagnosis and the ASRS; (2) met only the criteria for Clinical Diagnosis; or (3) met only the criteria of the ASRS. Our research shows that individuals with ADHD experience more problems with money management and are more affected by the media, friends, and brands compared with individuals without ADHD. Smoking and alcohol use disorders, accidents, being held back, and disciplinary actions often accompany ADHD in college students. To the best of our knowledge, the shopping attitudes of young adults with ADHD and the influence of the media, peers, family, and brands have not been studied until now.

    Full Text Available Student housing plays an essential role in the attainment of quality education. However, there has been significant evidence as regards the inadequacy of this essential facility among public universities in Nigeria. It was further observed that there is a paucity of information as regards this situation within the private institutions in the country. Based on this background this research was conducted to assess the students’ housing in private institutions, by determining the factors influencing students’ choice of residence and its effect on their academic performance. The study adopted a survey approach, with 216 students sampled through a structured questionnaire. Data gathered were analyzed using frequency, mean item score, and Mann-Whitney UTest. Results revealed that although gender has no relationship with students’ choice of residence, age and academic level does. The major factors influencing students’ choice of residence are: accommodation fee, quality of the environment, need for privacy, influence of friends/desire to be close to friends, and number of students within the building. The study also revealed that students’ on-campus rarely miss classes due to distance of their residence from their lecture halls, unlike their mates staying off-campus. However, they tend to miss classes as a result of inadequacy of needed facilities; a situation that is uncommon among those staying off-campus. As regards students Cumulative Grade Point Average (CGPA as a measure of their performance, the residence of students does not have any statistical relationship with their academic grades.

    This experiment aims to enhance the effectiveness of the Universal Power System (UPS) continuous testing process of the Electrical and Electronic Institute by applying work scheduling and time study methods. Initially, the standard time of testing process has not been considered that results of unaccurate testing target and also time wasting has been observed. As monitoring and reducing waste time for improving the efficiency of testing process, Yamazumi chart and job scheduling theory (North West Corner Rule) were applied to develop new work process. After the improvements, the overall efficiency of the process possibly increased from 52.8% to 65.6% or 12.7%. Moreover, the waste time could reduce from 828.3 minutes to 653.6 minutes or 21%, while testing units per batch could increase from 3 to 4 units. Therefore, the number of testing units would increase from 12 units up to 20 units per month that also contribute to increase of net income of UPS testing process by 72%.

    Exploiting the tremendous potential of the recently discovered reversible bidirectional shape-memory effect (rbSME) for biomedical applications requires switching temperatures in the physiological range. The recent strategy is based on the reduction of the melting temperature range (ΔT m ) of the actuating oligo(ε-caprolactone) (OCL) domains in copolymer networks from OCL and n-butyl acrylate (BA), where the reversible effect can be adjusted to the human body temperature. In addition, it is investigated whether an rbSME in the temperature range close or even above Tm,offset (end of the melting transition) can be obtained. Two series of networks having mixtures of OCLs reveal broad ΔTm s from 2 °C to 50 °C and from -10 °C to 37 °C, respectively. In cyclic, thermomechanical experiments the rbSME can be tailored to display pronounced actuation in a temperature interval between 20 °C and 37 °C. In this way, the application spectrum of the rbSME can be extended to biomedical applications. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The opening of the Thai tobacco market, following action brought by the US Trade Representative under the GATT, is seen as a key case study of the tensions between trade and health policy. Interpretations of the dispute cast it, either as an example of how trade agreements undermine national policy making, or how governments can adopt effective public health protections compliant with international trade rules. As a UK-based company, British American Tobacco has been regarded as peripheral to this dispute. This paper argues that its close monitoring of the illegal trade during this period, the role of smuggling in the company’s global business strategy, and its management of the relative supply and pricing of legal and illegal products after market opening provide a fuller understanding of the interests and roles of transnational tobacco companies and the government in this dispute. The findings have important policy implications, notably the role of effective governance in countries facing pressure to open their tobacco sectors, need to better understand corporate-level activities within an increasingly globalized tobacco industry, and need to address the intertwined legal and illegal trade in implementing the WHO Framework Convention on Tobacco Control Protocol to Eliminate Illicit Trade in Tobacco Products.

    Full Text Available Introduction: Higher education system in each country is mainly responsible for training specialists and efficient personnels in different levels of government. Regarding a community approach, if the system uses social factors properly, goals attainment will be facile. On the contrary, if the system is affected by common social traumas and deviations, it will result in dissonant maladroit graduated students who would trouble themselves, their family and their society. Addiction to narcotic drugs is one of the most important social traumas that is quite common in developing countries. Materials and Methods: The current descriptive analytic study has been conducted in community of Yazd University in academic year of 2010 -2011. For this purpose, 406 students of this university were selected via stratified random sampling method who responded to a researcher-made questionnaire that its validity and reliability were confirmed utilizing psychometric standards. Regarding data description, frequency indexes, percent, mean, and standard deviation were applied. Moreover, inferential tests of chi-square test and correlation coefficient of Pearson were utilized. Results: The study results revealed that approximately 21/9 percent of students were suggested the drug abuse whose rate of drug use was 25/9 percent. 34/1 percent of subjects determined their friend's homes as the most propitious place for their use and most important reasons involved respectively release of spiritual stress, inability to say "No" in response to others’ suggestion.

    Pneumococcal disease causes large morbidity, mortality and health care utilization and medical and non-medical costs, which can all be reduced by effective infant universal routine immunization programs with pneumococcal conjugate vaccines (PCV). We evaluated the clinical and economic benefits of such programs with either 10- or 13-valent PCVs in Malaysia and Hong Kong by using an age-stratified Markov cohort model with many country-specific inputs. The incremental cost per quality-adjusted life year (QALY) was calculated to compare PCV10 or PCV13 against no vaccination and PCV13 against PCV10 over a 10-year birth cohort's vaccination. Both payer and societal perspectives were used. PCV13 had better public health and economic outcomes than a PCV10 program across all scenarios considered. For example, in the base case scenario in Malaysia, PCV13 would reduce more cases of IPD (+2,296), pneumonia (+705,281), and acute otitis media (+376,967) and save more lives (+6,122) than PCV10. Similarly, in Hong Kong, PCV13 would reduce more cases of IPD cases (+529), pneumonia (+172,185), and acute otitis media (+37,727) and save more lives (+2,688) than PCV10. During the same time horizon, PCV13 would gain over 74,000 and 21,600 additional QALYs than PCV10 in Malaysia and Hong Kong, respectively. PCV13 would be cost saving when compared against similar program with PCV10, under both payer and societal perspective in both countries. PCV13 remained a better choice over PCV10 in multiple sensitivity, scenario, and probabilistic analyses. PCV13s broader serotype coverage in its formulation and herd effect compared against PCV10 were important drivers of differences in outcomes.

    Full Text Available Introduction: Nowadays, the employees` inservice training has become one of the core components in survival and success of any organization. Unfortunately, despite the importance of training evaluation, a small portion of resources are allocated to this matter. Among many evaluation models, the CIPP model or Context, Input, Process, Product model is a very useful approach to educational evaluation. So far, the evaluation of the training courses mostly provided information for learners but this investigation aims at evaluating the effectiveness of the experts’ training programs and identifying its pros and cons based on the 4 stages of the CIPP model. Method: In this descriptive analytical study, done in 2013, 250 employees of Shiraz University Medical Sciences (SUMS participated in inservice training courses were randomly selected. The evaluated variables were designed using CIPP model and a researcher-made questionnaire was used for data collection; the questionnaire was validated using expert opinion and its reliability was confirmed by Cronbach’s alpha (0.89. Quantitative data were analyzed using SPSS 14 and statistical tests was done as needed. Results: In the context phase, the mean score was highest in solving work problems (4.07±0.88 and lowest in focusing on learners’ learning style training courses (2.68±0.91. There is a statistically significant difference between the employees` education level and the product phase evaluation (p0.001, in contrast with the process and product phase which showed a significant deference (p<0.001. Conclusion: Considering our results, although the inservice trainings given to sums employees has been effective in many ways, it has some weaknesses as well. Therefore improving these weaknesses and reinforcing strong points within the identified fields in this study should be taken into account by decision makers and administrators.

    Sometimes the measures taken to make a radiology department more effective, such as prioritizing the workload and keeping equipment running for as many hours as staffing permits, are not enough. In such cases, outsourcing radiological examinations is a potential solution for reducing waiting times. To investigate differences in waiting time, quality and costs between magnetic resonance (MR) examinations performed in a university hospital and examinations outsourced to private service. We retrospectively selected a group of consecutive, outsourced MR examinations (n=97) and a control group of in-house MR examinations, matched for type of examination. In each group there were referrals that had a specified preferred timeframe for completion. We measured the percentage of cases in which this timeframe was met and if it was not met, how many days exceeded the preferred time. In referrals without a specified preferred timeframe, we also calculated the waiting time. Quality standards were measured by the percentage of examinations that had to be re-done and re-assessed. Finally, we calculated the cumulative costs, taking into account the costs for re-doing and re-assessing examinations. There was no statistically significant difference between the groups, in either the number of examinations that were not performed within the preferred time or the number of days that exceeded the preferred timeframe. For referrals without a preferred timeframe, the waiting time was shorter for outsourced examinations than those not outsourced. There were no differences in the number of examinations that had to be re-done, but more examinations needed to be re-assessed in the outsourced group than in the in-house group. The calculated costs for outsourced examinations were lower than the costs for internally performed examinations. Outsourcing magnetic resonance examinations may be an effective way of reducing a radiology department's workload. Ways in which to reduce the additional costs

    Full Text Available BACKGROUND: Relatively little is known about the peer influence in health behaviors within university dormitory rooms. Moreover, in China, the problem of unhealthy behaviors among university students has not yet been sufficiently recognized. We thus investigated health behavior peer influence in Peking University dormitories utilizing a randomized cluster-assignment design. METHODS: STUDY DESIGN: Cross-sectional in-dormitory survey. STUDY POPULATION: Current students from Peking University Health Science Center from April to June, 2009. MEASUREMENT: Self-reported questionnaire on health behaviors: physical activity (including bicycling, dietary intake and tobacco use. RESULTS: Use of bicycle, moderate-intensity exercise, frequency of sweet food and soybean milk intake, frequency of roasted/baked/toasted food intake were behaviors significantly or marginally significantly affected by peer influence. CONCLUSION: Health behavior peer effects exist within dormitory rooms among university students. This could provide guidance on room assignment, or inform intervention programs. Examining these may demand attention from university administrators and policy makers.

    Full Text Available OBJETIVO: Evaluar la relación costo-efectividad del programa de vacunación universal con la vacuna antineumocócica conjugada heptavalente (VCN7 en niños menores de 5 años en Uruguay. MÉTODOS: Se desarrolló un modelo Markov simulando una cohorte de 48 000 niños nacidos en 2007 y su evolución hasta los 76 años de edad. El caso base usó un esquema de tres dosis con una duración estimada de protección de cinco años. La presunción de eficacia y efectividad de la vacuna se realizó acorde con estudios realizados en Estados Unidos con ajuste a la prevalencia-incidencia de serotipos en Uruguay. Los resultados se expresaron como costo incremental por año de vida ganado (AVG y por año de vida [ganado] ajustado por calidad (AVAC. RESULTADOS: Para el caso base, el costo incremental fue de US$ 7 334,6 por AVG y US$ 4 655,8 por AVAC, previniéndose 8 muertes y 4 882 casos de otitis, 56 bacteriemias-sepsis, 429 neumonías y 7 meningitis. El modelo muestra sensibilidad a variaciones en eficacia, costo de la vacuna y tasa de mortalidad por neumonía. CONCLUSIONES: El programa de vacunación universal con VCN7 en Uruguay es altamente costo-efectivo y, en consecuencia, recomendable para otros países con carga de enfermedad neumocócica y cobertura de serotipos similares a Uruguay.OBJECTIVE: Evaluate the cost-effectiveness ratio of the program for universal vaccination with heptavalent pneumococcal conjugate vaccine (PCV7 in children under 5 years of age in Uruguay.

    Full Text Available Primaquine is the only licensed antimalarial for the radical cure of Plasmodium vivax infections. Many countries, however, do not administer primaquine due to fear of hemolysis in those with glucose-6-phosphate dehydrogenase (G6PD deficiency. In other settings, primaquine is given without G6PD testing, putting patients at risk of hemolysis. New rapid diagnostic tests (RDTs offer the opportunity to screen for G6PD deficiency prior to treatment with primaquine. Here we assessed the cost-effectiveness of using G6PD RDTs on the Thailand-Myanmar border and provide the model as an online tool for use in other settings.Decision tree models for the management of P. vivax malaria evaluated the costs and disability-adjusted life-years (DALYs associated with recurrences and primaquine-induced hemolysis from a health care provider perspective. Screening with G6PD RDTs before primaquine use was compared to (1 giving chloroquine alone and (2 giving primaquine without screening. Data were taken from a recent study on the impact of primaquine on P. vivax recurrences and a literature review. Compared to the use of chloroquine alone, the screening strategy had similar costs while averting 0.026 and 0.024 DALYs per primary infection in males and females respectively. Compared to primaquine administered without screening, the screening strategy provided modest cost savings while averting 0.011 and 0.004 DALYs in males and females respectively. The probabilistic sensitivity analyses resulted in a greater than 75% certainty that the screening strategy was cost-effective at a willingness to pay threshold of US$500, which is well below the common benchmark of per capita gross domestic product for Myanmar.In this setting G6PD RDTs could avert DALYs by reducing recurrences and reducing hemolytic risk in G6PD deficient patients at low costs or cost savings. The model results are limited by the paucity of data available in the literature for some parameter values

    Behavioral trajectories during middle childhood are predictive of consequential outcomes later in life (e.g., substance abuse, violence). Social and emotional learning (SEL) programs are designed to promote trajectories that reflect both growth in positive behaviors and inhibited development of negative behaviors. The current study used growth mixture models to examine effects of the Positive Action (PA) program on behavioral trajectories of social-emotional and character development (SECD) and misconduct using data from a cluster-randomized trial that involved 14 schools and a sample of predominately low-income, urban youth followed from 3rd through 8th grade. For SECD, findings indicated that PA was similarly effective at improving trajectories within latent classes characterized as "high/declining" and "low/stable". Favorable program effects were likewise evident to a comparable degree for misconduct across observed latent classes that reflected "low/rising" and "high/rising" trajectories. These findings suggest that PA and perhaps other school-based universal SEL programs have the potential to yield comparable benefits across subgroups of youth with differing trajectories of positive and negative behaviors, making them promising strategies for achieving the intended goal of school-wide improvements in student outcomes.

    Atomic layer deposition (ALD) of Aluminum oxide (Al2O3) is employed to optimize the back contact of thin film CdTe solar cells. Al2O3 layers with a thickness of 0.5 nm to 5 nm are tested, and an improved efficiency, up to 12.1%, is found with the 1 nm Al2O3 deposition, compared with the efficiency of 10.7% without Al2O3 modification. The performance improvement stems from the surface modification that optimizes the rectification and tunneling of back contact. The current-voltage analysis indicates that the back contact with 1 nm Al2O3 maintains large tunneling leakage current and improves the filled factor of CdTe cells through the rectification effect. XPS and capacitance-voltage electrical measurement analysis show that the ALD-Al2O3 modification layer features a desired low-density of interface state of 8 × 1010 cm-2 by estimation.

    2016-12-01

    Full Text Available This study explores the mechanism by which mobility influences university entrepreneurship through an empirical analysis of Japanese scientists working for the University of Tokyo. It presents theory-driven typology of mobility and applies it to the knowledge-transfer context.  First, this paper subdivides previously-studied mobility into four types – job mobility (JM, sector mobility (SM, international mobility (IM, and the educational background mobility (EBM. Then, it empirically shows that both JM and IM have positive and significant correlation with university entrepreneurship, whereas neither SM nor EBM does. Based on the result, this study discusses that JM and IM accelerate the formation of skills necessary for the commercialization of university research; however, SM and EBM may have no impact on it.

    This paper examines knowledge creation in relation to improvements on the production line in the manufacturing department of Nissan Motor Company and aims to clarify embodied knowledge observed in the actions of organisational members who enable knowledge creation will be clarified. For that purpose, this study adopts an approach that adds a first, second, and third-person's viewpoint to the theory of knowledge creation. Embodied knowledge, observed in the actions of organisational members who enable knowledge creation, is the continued practice of 'ethos' (in Greek) founded in Nissan Production Way as an ethical basis. Ethos is knowledge (intangible) assets for knowledge creating companies. Substantiated analysis classifies ethos into three categories: the individual, team and organisation. This indicates the precise actions of the organisational members in each category during the knowledge creation process. This research will be successful in its role of showing the indispensability of ethos - the new concept of knowledge assets, which enables knowledge creation -for future knowledge-based management in the knowledge society.

    Predicting species vulnerability to global warming requires a comprehensive, mechanistic understanding of sublethal and lethal thermal tolerances. To date, however, most studies investigating species physiological responses to increasing temperature have focused on the underlying physiological traits of either acute or chronic tolerance in isolation. Here we propose an integrative, synthetic approach including the investigation of multiple physiological traits (metabolic performance and thermal tolerance), and their plasticity, to provide more accurate and balanced predictions on species and assemblage vulnerability to both acute and chronic effects of global warming. We applied this approach to more accurately elucidate relative species vulnerability to warming within an assemblage of six caridean prawns occurring in the same geographic, hence macroclimatic, region, but living in different thermal habitats. Prawns were exposed to four incubation temperatures (10, 15, 20 and 25 °C) for 7 days, their metabolic rates and upper thermal limits were measured, and plasticity was calculated according to the concept of Reaction Norms, as well as Q10 for metabolism. Compared to species occupying narrower/more stable thermal niches, species inhabiting broader/more variable thermal environments (including the invasive Palaemon macrodactylus) are likely to be less vulnerable to extreme acute thermal events as a result of their higher upper thermal limits. Nevertheless, they may be at greater risk from chronic exposure to warming due to the greater metabolic costs they incur. Indeed, a trade-off between acute and chronic tolerance was apparent in the assemblage investigated. However, the invasive species P. macrodactylus represents an exception to this pattern, showing elevated thermal limits and plasticity of these limits, as well as a high metabolic control. In general, integrating multiple proxies for species physiological acute and chronic responses to increasing

    The Thomas-Fermi approach to galaxy structure determines self-consistently and non-linearly the gravitational potential of the fermionic warm dark matter (WDM) particles given their quantum distribution function f(E). This semiclassical framework accounts for the quantum nature and high number of DM particles, properly describing gravitational bounded and quantum macroscopic systems as neutron stars, white dwarfs and WDM galaxies. We express the main galaxy magnitudes as the halo radius r{sub h}, mass M{sub h}, velocity dispersion and phase space density in terms of the surface density which is important to confront to observations. From these expressions we derive the general equation of state for galaxies, i.e., the relation between pressure and density, and provide its analytic expression. Two regimes clearly show up: (1) Large diluted galaxies for M{sub h} >or similar 2.3 x 10{sup 6} M {sub CircleDot} and effective temperatures T{sub 0} > 0.017 K described by the classical self-gravitating WDM Boltzman gas with a space-dependent perfect gas equation of state, and (2) Compact dwarf galaxies for 1.6 x 10{sup 6} M {sub CircleDot} >or similar M{sub h} >or similar M{sub h,min} ≅ 3.10 x 10{sup 4} (2 keV/m){sup (16)/(5)} M {sub CircleDot}, T{sub 0} < 0.011 K described by the quantum fermionic WDM regime with a steeper equation of state close to the degenerate state. In particular, the T{sub 0} = 0 degenerate or extreme quantum limit yields the most compact and smallest galaxy. In the diluted regime, the halo radius r{sub h}, the squared velocity v{sup 2}(r{sub h}) and the temperature T{sub 0} turn to exhibit square-root of M{sub h} scaling laws. The normalized density profiles ρ(r)/ρ(0) and the normalized velocity profiles v{sup 2}(r)/v{sup 2}(0) are universal functions of r/r{sub h} reflecting the WDM perfect gas behavior in this regime. These theoretical results contrasted to robust and independent sets of galaxy data remarkably reproduce the observations. For

    Full Text Available Aim/Purpose: The number of students enrolled in online courses that use video lectures is on the rise. However, research shows that the number of students watching video lectures is low, and the number watching videos to completion is even lower. Background: This paper seeks to understand this problem by looking for correlations between instructional design and student engagement with video lectures. Methodology: Students at a cyber-university in South Korea (n=1801 were surveyed on their perception of the instructional design used in the courses they took and their engagement with online video lectures. Contribution: This paper contributes to the body of knowledge by demonstrating positive correlations between instructional design, watching, and finishing video lectures. Findings: While most other research has found low levels of online lecture viewership, this paper found significantly higher numbers watching and finishing videos. Other major findings of the paper are that five key elements of instructional design for online learning environments (designing methods, setting the curriculum, establishing time parameters, establishing netiquette, and utilizing the medium effectively all correlated positively with students watching and finishing video lectures. Recommendations for Practitioners\t: Based on findings in this paper, it is recommended that practitioners consider taking actions when designing their instruction for online courses. These include batching their video lectures together by topic, devoting greater resources to helping students utilize the medium, and communicate time parameters in a way that encourages students to view video lectures in a timely manner. Recommendation for Researchers: As the watching of video lectures in this study was mandatory for learners, an interesting area of further research would be to examine whether that decision led to higher numbers of students watching them. Future Research: It is important for

    This report presents a discussion of directory-enabled policy-based networking with an emphasis on its role as the foundation for securely scalable enterprise networks. A directory service provides the object-oriented logical environment for interactive cyber-policy implementation. Cyber-policy implementation includes security, network management, operational process and quality of service policies. The leading network-technology vendors have invested in these technologies for secure universal connectivity that transverses Internet, extranet and intranet boundaries. Industry standards are established that provide the fundamental guidelines for directory deployment scalable to global networks. The integration of policy-based networking with directory-service technologies provides for intelligent management of the enterprise network environment as an end-to-end system of related clients, services and resources. This architecture allows logical policies to protect data, manage security and provision critical network services permitting a proactive defense-in-depth cyber-security posture. Enterprise networking imposes the consideration of supporting multiple computing platforms, sites and business-operation models. An industry-standards based approach combined with principled systems engineering in the deployment of these technologies allows these issues to be successfully addressed. This discussion is focused on a directory-based policy architecture for the heterogeneous enterprise network-computing environment and does not propose specific vendor solutions. This document is written to present practical design methodology and provide an understanding of the risks, complexities and most important, the benefits of directory-enabled policy-based networking

    Universities and higher education institutions form an integral part of the national infrastructure and prestige. As academic research benefits increasingly from international exchange and cooperation, many universities have increased investment in improving and enabling their global connectivity. Yet, the relationship of university performance and its global physical connectedness has not been explored in detail. We conduct, to our knowledge, the first large-scale data-driven analysis into whether there is a correlation between university relative ranking performance and its global connectivity via the air transport network. The results show that local access to global hubs (as measured by air transport network betweenness) strongly and positively correlates with the ranking growth (statistical significance in different models ranges between 5% and 1% level). We also found that the local airport's aggregate flight paths (degree) and capacity (weighted degree) has no effect on university ranking, further showing that global connectivity distance is more important than the capacity of flight connections. We also examined the effect of local city economic development as a confounding variable and no effect was observed suggesting that access to global transportation hubs outweighs economic performance as a determinant of university ranking. The impact of this research is that we have determined the importance of the centrality of global connectivity and, hence, established initial evidence for further exploring potential connections between university ranking and regional investment policies on improving global connectivity.

    Full Text Available The article is devoted to search of the solution of urgent problems of recruiting of foreign students in the Russian higher education institutions. Nowadays, in Russia the term «foreign students» is used, whereas the most part of world educational community uses the concept «international students». Distinction of concepts is connected with different methods of accounting of this category of students. Effective accounting, in turn, influences the quality of further interaction with international target audience, gives the chance of competent forming of a profile of the student and the choice of effective instruments of recruiting. Methods. The methods of comparative analysis of approaches to content of the concepts «foreign students» and «international students» are used.Results. The results of researches of the foreign and Russian authors concerning internationalization of universities and involvement of students from abroad are analysed. The concepts «foreign students» and «international students» are structured and divided. The proposals on the need of a right choice of determination for further successful recruiting according to the purposes of internationalization of higher education institutions are developed. The results of the present research have showed that further processes of involvement of students from abroad in the Russian higher educational institutions depend on the choice of a method of accounting and the corresponding terminology, arrangement of emphases on formal or substantial criteria, i. e. on indicators of internationalization or the purposes of internationalization.Scientific novelty. It is convincingly proved that new approaches to recruiting of foreign students are required in the longer term for increase of a level of internationalization of higher education institution: transition from tactical line items to strategic tasks; forming of a profile of a potential student as international, but not as a

    Repeat pregnancies after a short interpregnancy interval are common and are associated with negative maternal and infant health outcomes. Few studies have examined the relative effectiveness of postpartum contraceptive choices. We aimed to determine the initiation trends and relative effectiveness of postpartum contraceptive methods, with typical use, on prevention of short delivery intervals (≤27 months) among women with access to universal healthcare, including coverage that entails no co-payments and allows unlimited contraceptive method switching. This retrospective cohort study included women who were enrolled in the United States military healthcare system who were admitted for childbirth between October 2010 and March 2015, with ≥6 months postpartum enrollment. With the use of insurance records, we determined the most effective contraceptive method initiated during the first 6 months after delivery, even if subsequently discontinued. Rates of interdelivery intervals of ≤27 months, as proxies for interpregnancy intervals ≤18 months, were determined with the use of the Kaplan-Meier estimator. Women who were disenrolled, who reached 27 months after delivery without another delivery, or who reached the end of the study period were censored. The influence of sociodemographic variables and contraceptive choices on time to subsequent delivery was evaluated by Cox regression analysis, which accounted for a possible correlation among multiple deliveries by an individual woman. During the study timeframe, 373,840 women experienced a total of 450,875 postpartum intervals. Women averaged 27 (standard deviation, 5.3) years of age at the time of delivery; 33.9% of them were contraceptive methods that were initiated included self or partner sterilization (7%), intrauterine device (13.5%), etonogestrel implant (3.4%), depot medroxyprogesterone acetate (2.5%), and pill, patch, or ring (36.8%). Furthermore, 36.7% of them did not initiate a prescription method

    2017-03-01

    Full Text Available A new type of one-step self-etch adhesives classified as "Universal" or "multi-mode" adhesives appeared in recent years. The idea is that these adhesives can be applied simultaneously with both techniques - etch and rinse and with self-etching technique, without compromising the bonding effectiveness. The aim of this study is to evaluate the micro-tensile adhesive bond strength to dentin of permanent teeth achieved after application of Single Bond Universal (3M ESPE adhesive system used in multi-mode manner. The results of our study show that the use of this universal adhesive system in multi-mode manner will not lead to the same results regarding the achieved bond strength with dentin. The additional etching with 37% phosphoric acid as well as the application of the adhesive in several layers deteriorates the bond strength right after application and after six months storage in artificial saliva medium (SAGF.

    This study analyzes the influence that experienced users of university resources might have as narrative sources of information for other students in the process of choosing their schools. Informative videos about the benefits of studying at the university provide a reference model. In these videos, a group of young people present their views and explain their reasons for choosing the university in which they are pursuing their degrees; the various narrators detail all the resources available. This study investigates whether the individual identifiers of these narrators (e.g., gender, age, physical appearance, nonverbal gestures such as smiling, posture) influence perceptions of the credibility of the information they provide. Among a sample of 150 students in their last year of pre-university training, the results demonstrate that the students' ability to identify with the narrators provides information and arouses emotions that inform their perceptions of reliability and therefore their consumption choices. None of these predictors appear to serve as determinants that can be generalized, but if emotional attitudes in response to narratives about the topic (i.e., the university) are positive, then they prompt a change in attitude toward that reference topic too.

    The medical laboratory of Tokushima University Hospital acquired ISO 15189, an international standard for medical laboratories, on July 6th, 2007, resulting in it achieving the 24th place in Japan and 5th place among national university hospitals. The first surveillance was just performed on October 6th, 2008. Tokushima University Hospital, in which our medical laboratory is included as one section, already succeeded in acquiring ISO 9001, PrivacyMark System, and Quality Health Care ver. 5 before accomplishing ISO 15189. To achieve ISO 15189, we prepared documents based on ISO 9001 without any consultation, resulting in a review of the difference between ISO 9001 and ISO 15189 after the preliminary survey. Although achieving ISO 15189 resulted in an improvement in the reliability of laboratory results and accuracy, leading to the development of our technical skills and awareness, and sharing of knowledge, we consider that the considerable investment of time to prepare the requirements remains to be overcome.

    Full Text Available The fundamental factor of environmental education is teachers who are well-informed about environmental issues. This research aimed to determine prospective Turkish elementary science teachers’ knowledge level about causes, consequences and reducing of the greenhouse effect and to investigate the effect of gender, information source and membership in the environmental foundations on their knowledge. We also aimed to learn their views on environmental education given in university. Twenty-six Likert-scale items developed by Cin (2006 were used for data collection. The scale was applied to 215 prospective teachers from two universities in eastern Turkey. Results indicated that the majority of prospective teachers had misunderstandings about causes, consequences and reducing of the greenhouse effect. According to the analysis of demographic variables, there were significant differences in participants’ mean scores based on gender and information sources. Additionally, prospective teachers found environmental education inadequate for different reasons.

    Science.gov (United States)

    Langer, J. S.

    2017-11-01

    The thermodynamic theory of dislocation-enabled plasticity is based on two unconventional hypotheses. The first of these is that a system of dislocations, driven by external forces and irreversibly exchanging heat with its environment, must be characterized by a thermodynamically defined effective temperature that is not the same as the ordinary temperature. The second hypothesis is that the overwhelmingly dominant mechanism controlling plastic deformation is thermally activated depinning of entangled pairs of dislocations. This paper consists of a systematic reformulation of this theory followed by examples of its use in analyses of experimentally observed phenomena including strain hardening, grain-size (Hall-Petch) effects, yielding transitions, and adiabatic shear banding.

University students were surveyed on how they typically responded when under perceived stress. There were significant differences between males and females concerning their reactions to stress. Overall, more females experienced higher levels of depression, frustration, and anxiety than their male counterparts when reacting to stress. Males also tended to have other psychological reactions different from those listed on the survey. In addition, while the stress reaction of anger was barely statistically insignificant, more females expressed anger than males as a reaction to stress.

    The Fuel Properties to Enable Lifted-Flame Combustion project responded directly to solicitation DE-FOA-0000239 AOI 1A, Fuels and Lubricants for Advanced Combustion Regimes. This subtopic was intended to encompass clean and highly-efficient, liquid-fueled combustion engines to achieve extremely low engine-out nitrogen oxides (NOx) and particulate matter (PM) as a target and similar efficiency as state-of-the-art direct injection diesel engines. The intent of this project was to identify how fuel properties can be used to achieve controllable Leaner Lifted Flame Combustion (LLFC) with low NOx and PM emissions. Specifically, this project was expected to identify and test key fuel properties to enable LLFC and their compatibility with current fuel systems and to enhance combustion models to capture the effect of fuel properties on advanced combustion. Successful demonstration of LLFC may reduce the need for after treatment devices, thereby reducing costs and improving thermal efficiency. The project team consisted of key technical personnel from Ford Motor Company (FMC), the University of Wisconsin-Madison (UW), Sandia National Laboratories (SNL) and Lawrence Livermore National Laboratories (LLNL). Each partner had key roles in achieving project objectives. FMC investigated fuel properties relating to LLFC and sooting tendency. Together, FMC and UW developed and integrated 3D combustion models to capture fuel property combustion effects. FMC used these modeling results to develop a combustion system and define fuel properties to support a single-cylinder demonstration of fuel-enabled LLFC. UW investigated modeling the flame characteristics and emissions behavior of different fuels, including those with different cetane number and oxygen content. SNL led spray combustion experiments to quantify the effect of key fuel properties on combustion characteristics critical for LLFC, as well as single cylinder optical engine experiments to improve fundamental

  2. Self-accelerated Universe Induced by Repulsive Effects as an Alternative to Dark Energy and Modified Gravities

    Science.gov (United States)

    Luongo, Orlando; Quevedo, Hernando

    2018-01-01

    The existence of current-time universe's acceleration is usually modeled by means of two main strategies. The first makes use of a dark energy barotropic fluid entering by hand the energy-momentum tensor of Einstein's theory. The second lies on extending the Hilbert-Einstein action giving rise to the class of extended theories of gravity. In this work, we propose a third approach, derived as an intrinsic geometrical effect of space-time, which provides repulsive regions under certain circumstances. We demonstrate that the effects of repulsive gravity naturally emerge in the field of a homogeneous and isotropic universe. To this end, we use an invariant definition of repulsive gravity based upon the behavior of the curvature eigenvalues. Moreover, we show that repulsive gravity counterbalances the standard gravitational attraction influencing both late and early times of the universe evolution. This phenomenon leads to the present speed up and to the fast expansion due to the inflationary epoch. In so doing, we are able to unify both dark energy and inflation in a single scheme, showing that the universe changes its dynamics when {\\ddot{H}\\over H}=-2 \\dot{H}, at the repulsion onset time where this condition is satisfied. Further, we argue that the spatial scalar curvature can be taken as vanishing because it does not affect at all the emergence of repulsive gravity. We check the goodness of our approach through two cosmological fits involving the most recent union 2.1 supernova compilation.

    2017-10-01

    Drawing on a comprehensive, pan-national analysis of the corporatization of Canadian universities, as well as the notions of 'parrhesiastic' mentorship and practice, the authors examine the effects of the corporatized university, its implications for graduate nursing education and nursing's relative silence on the subject. With the preponderance of business interests, the increasing dependence of universities on industry funding, cults of efficiency, research intensivity, and the pursuit of profit so prevalent in today's corporatized university, we argue that philosophical presuppositions so crucial to critical teaching, research, and reflection on nursing as a discipline are troublingly losing ground. We lament the erosion and fragmentation of philosophy, politics, and ethics as foundations for graduate education, which are increasingly perceived as less valuable, problematic, and in some cases, even burdensome. The effect of corporatization is the suppression of the critical engagement required of faculty in the everyday workings of institutions. We argue that, when the ideals of intellectual freedom, academic responsibility, duty, and obligation, as supported by philosophical thought, are smothered by the normalizing power of corporatized research agendas, philosophical approaches to inquiry and knowledge development become marginalized as scholars find themselves floundering in the face of a seeming 'philosophy lost'. © 2017 John Wiley & Sons Ltd.

    Edwards, Jan; Beckman, Mary E

    2008-04-01

    While broad-focus comparisons of consonant inventories across children acquiring different language can suggest that phonological development follows a universal sequence, finer-grained statistical comparisons can reveal systematic differences. This cross-linguistic study of word-initial lingual obstruents examined some effects of language-specific frequencies on consonant mastery. Repetitions of real words were elicited from 2- and 3-year-old children who were monolingual speakers of English, Cantonese, Greek, or Japanese. The repetitions were recorded and transcribed by an adult native speaker for each language. Results found support for both language-universal effects in phonological acquisition and for language-specific influences related to phoneme and phoneme sequence frequency. These results suggest that acquisition patterns that are common across languages arise in two ways. One influence is direct, via the universal constraints imposed by the physiology and physics of speech production and perception, and how these predict which contrasts will be easy and which will be difficult for the child to learn to control. The other influence is indirect, via the way universal principles of ease of perception and production tend to influence the lexicons of many languages through commonly attested sound changes.

    Full Text Available Research on the accelerated expansion of our Universe captures a lot of attention. The dark energy (DE is a way to explain it. In this paper we will consider scalar field quintessence DE with ωDE>-1 EoS, where the dynamics of the DE models related to the dynamics of the scalar field. We are interested in the study of the behavior of the Universe in the presence of interacting quintessence DE models in Lyra manifold with a varying Λt. In a considered framework we also would like to propose a new form for Λt. We found that the models correspond to the transit Universe, which will enter the accelerated expansion phase and will remain there with a constant deceleration parameter q. We found also that the Λt is a decreasing function which takes a small positive value with Ωm≠0 and ΩQ→const dominating Ωm in the old Universe. Observational constraints are applied and causality issue via CS2 is discussed as a possible way to either reject or accept the models.

  10. Possible Simple Structures of the Universe to Include General Relativity Effects

    Full Text Available The general relativity describes the universe properties, the gravity playing a fundamental role. One uses a metric tensor in a Riemann space, g  , which should be in agreement with a mass (or energy tensor in order to satisfy the Einstein equation of the general relativity [1]. This equation contains the Ricci curvature as well. In general, applications are done considering that a chosen metric is valid without region limits. In fact, the density of the energy whose distribution is however unknown is variable in universe; therefore, the metrics need to be adapted to different regions. For this reason one suggests to start with a simple, average mass-energy distribution that could represent in a first step the actual universe. This suggestion is in agreement with the symmetrical distribution of equal spheres existing in a model of the early universe given by one of the authors. Two kinds of distribution are given. The possibility of black holes formation is studied and a criterion is given.
