    A giant magnetoresistive flux focusing eddy current device effectively detects deep flaws in thick multilayer conductive materials. The probe uses an excitation coil to induce eddy currents in conducting material perpendicularly oriented to the coil's longitudinal axis. A giant magnetoresistive (GMR) sensor, surrounded by the excitation coil, is used to detect generated fields. Between the excitation coil and GMR sensor is a highly permeable flux focusing lens which magnetically separates the GMR sensor and excitation coil and produces high flux density at the outer edge of the GMR sensor. The use of feedback inside the flux focusing lens enables complete cancellation of the leakage fields at the GMR sensor location and biasing of the GMR sensor to a location of high magnetic field sensitivity. In an alternate embodiment, a permanent magnet is positioned adjacent to the GMR sensor to accomplish the biasing. Experimental results have demonstrated identification of flaws up to 1 cm deep in aluminum alloy structures. To detect deep flaws about circular fasteners or inhomogeneities in thick multilayer conductive materials, the device is mounted in a hand-held rotating probe assembly that is connected to a computer for system control, data acquisition, processing and storage.

    This report describes the work performed at Berkeley Lab most recently. One of the Labs accomplishments is the publication of Scenarios of US Carbon Reductions, an analysis of the potential of energy technologies to reduce carbon emissions in the US. This analysis is described and played a key role in shaping the US position on climate change in the Kyoto Protocol negotiations. The Labs participation in the fundamental characterization of the climate change issue by the IPCC is described. Described also is a study of leaking electricity, which is stimulating an international campaign for a one-watt ceiling for standby electricity losses from appliances. This ceiling has the potential to save two-thirds of the 5% of US residential electricity currently expended on standby losses. The 54 vignettes contained in the report summarize results of research activities ranging in scale from calculating the efficacy of individual lamp ballasts to estimating the cost-effectiveness of the national Energy Star{reg_sign} labeling program, and ranging in location from a scoping study of energy-efficiency market transformation in California to development of an energy-efficiency project in the auto parts industry in Shandong Province, China.

    We propose the use of a combination of ultrasonic and magnetic fields in conductive media for the creation of RF electrical current via the Lorentz force, in order to achieve current generation with extreme sub-wavelength resolution at large depth. We demonstrate the modeling, generation, and measurement of Lorentz current in a conductive solution and show that this current can be localized at a distance of 13 cm from the ultrasonic source to a region about three orders of magnitude smaller than the corresponding wavelength of electromagnetic waves at the same operation frequency. Our results exhibit greater depth, tighter localization, and closer agreement with prediction than previous work on the measurement of Lorentz current in a solution of homogeneous conductivity. The proposed method of RF current excitation overcomes the trade-off between focusing and propagation that is fundamental in the use of RF electromagnetic excitation alone and has the potential to improve localization and depth of operation for RF current-based biomedical applications.

    2008-08-01

    Current steering and current focusing are stimulation techniques designed to increase the number of distinct perceptual channels available to cochlear implant (CI) users by adjusting currents applied simultaneously to multiple CI electrodes. Previous studies exploring current steering and current focusing stimulation strategies are reviewed, including results of research using computational models, animal neurophysiology, and human psychophysics. Preliminary results of additional neurophysiological and human psychophysical studies are presented that demonstrate the success of current steering strategies in stimulating auditory nerve regions lying between physical CI electrodes, as well as current focusing strategies that excite regions narrower than those stimulated using monopolar configurations. These results are interpreted in the context of perception and speech reception by CI users. Disparities between results of physiological and psychophysical studies are discussed. The differences in stimulation used for physiological and psychophysical studies are hypothesized to contribute to these disparities. Finally, application of current steering and focusing strategies to other types of auditory prostheses is also discussed.

    The relevance of retinal diseases, both in society'seconomy and in the quality of people's life who suffer withthem, has made stem cell therapy an interesting topic forresearch. Embryonic stem cells (ESCs), induced pluripotentstem cells (iPSCs) and adipose derived mesenchymal stemcells (ADMSCs) are the focus in current endeavors as asource of different retinal cells, such as photoreceptorsand retinal pigment epithelial cells. The aim is to applythem for cell replacement as an option for treating retinaldiseases which so far are untreatable in their advancedstage. ESCs, despite the great potential for differentiation,have the dangerous risk of teratoma formation as wellas ethical issues, which must be resolved before startinga clinical trial. iPSCs, like ESCs, are able to differentiatein to several types of retinal cells. However, the processto get them for personalized cell therapy has a high costin terms of time and money. Researchers are working toresolve this since iPSCs seem to be a realistic option fortreating retinal diseases. ADMSCs have the advantagethat the procedures to obtain them are easier. Despiteadvancements in stem cell application, there are stillseveral challenges that need to be overcome beforetransferring the research results to clinical application.This paper reviews recent research achievements of theapplications of these three types of stem cells as well asclinical trials currently based on them.

    The Mediterranean Forecasting System (MFS) is a numerical ocean prediction system that produces analyses, reanalyses and short term forecasts for the entire Mediterranean Sea and its Atlantic Ocean adjacent areas. MFS became operational in the late 90's and has been developed and continuously improved in the framework of a series of EU and National funded programs and is now part of the Copernicus Marine Service. The MFS is composed by the hydrodynamic model NEMO (Nucleus for European Modelling of the Ocean) 2-way coupled with the third generation wave model WW3 (WaveWatchIII) implemented in the Mediterranean Sea with 1/16 horizontal resolution and forced by ECMWF atmospheric fields. The model solutions are corrected by the data assimilation system (3D variational scheme adapted to the oceanic assimilation problem) with a daily assimilation cycle, using a background error correlation matrix varying seasonally and in different sub-regions of the Mediterranean Sea. The focus of this work is to present the latest modelling system upgrades and the related achieved improvements. In order to evaluate the performance of the coupled system a set of experiments has been built by coupling the wave and circulation models that hourly exchange the following fields: the sea surface currents and air-sea temperature difference are transferred from NEMO model to WW3 model modifying respectively the mean momentum transfer of waves and the wind speed stability parameter; while the neutral drag coefficient computed by WW3 model is passed to NEMO that computes the turbulent component. In order to validate the modelling system, numerical results have been compared with in-situ and remote sensing data. This work suggests that a coupled model might be capable of a better description of wave-current interactions, in particular feedback from the ocean to the waves might assess an improvement on the prediction capability of wave characteristics, while suggests to proceed toward a fully

    Federal Manufacturing & Technologies/New Mexico (FM&T/NM) of AlliedSignal is an organization of approximately 300 associates providing operations support, engineering, and other technical services for DOE, New Mexico`s National Laboratories, etc. Work performed is primarily project-oriented and ranges from executing a major long-term contract for retrofitting and maintaining a large fleet of escort vehicles to creating a single, small, prototype electronic device for measuring radiation in a unique environment. FM&T/NM is functionally organized and operates in a classic matrix format with functional departments providing personnel with technical expertise, necessary physical resources, and administrative support to several project-based groups. Like most matrix-based organizations that provide support to diverse customers, FM&T/NM has encountered problems that occur when a group of project managers is expected to work together in using and scheduling a shared set of limited resources for the good of the organization as a whole. The framework for managing projects that we present focuses on developing, understanding, and managing the relationships between the functional organization structure, the system of work processes, and the management of projects. FM&T/NM retains its functional structure which primarily assigns personnel to work processes. The evolving role of the process leader focuses primarily on designing, managing, and improving the process, and the interactions among the subprocesses. The project manager is responsible for (1) translating customer requirements into product specifications, (2) determining the sequence of activities needed to meet project goals, (3) scheduling the required work processes, (4) monitoring project progress, (5) providing liaison between the customer and process leaders, and (6) having the desired product and/or service delivered to a satisfied customer in a timely manner.

  13. The Focus of Attention in Visual Working Memory: Protection of Focused Representations and Its Individual Variation

    2016-01-01

    Visual working memory can be modulated according to changes in the cued task relevance of maintained items. Here, we investigated the mechanisms underlying this modulation. In particular, we studied the consequences of attentional selection for selected and unselected items, and the role of individual differences in the efficiency with which attention is deployed. To this end, performance in a visual working memory task as well as the CDA/SPCN and the N2pc, ERP components associated with visual working memory and attentional processes, were analysed. Selection during the maintenance stage was manipulated by means of two successively presented retrocues providing spatial information as to which items were most likely to be tested. Results show that attentional selection serves to robustly protect relevant representations in the focus of attention while unselected representations which may become relevant again still remain available. Individuals with larger retrocueing benefits showed higher efficiency of attentional selection, as indicated by the N2pc, and showed stronger maintenance-associated activity (CDA/SPCN). The findings add to converging evidence that focused representations are protected, and highlight the flexibility of visual working memory, in which information can be weighted according its relevance.

    2008-04-01

    Dense Plasma Focus (DPF) devices' applications, which are intended to support the main-stream large-scale nuclear fusion programs (NFP) from one side (both in fundamental problems of Dense Magnetized Plasma physics and in its engineering issues) as well as elaborated for an immediate use in a number of fields from the other one, are described. In the first direction such problems as self-generated magnetic fields, implosion stability of plasma shells having a high aspect ratio, etc. are important for the Inertial Confinement Fusion (ICF) programs (e.g. as NIF), whereas different problems of current disruption phenomenon, plasma turbulence, mechanisms of generation of fast particles and neutrons in magnetized plasmas are of great interest for the large devices of the Magnetic Plasma Confinement—MPC (e.g. as ITER). In a sphere of the engineering problems of NFP it is shown that in particular the radiation material sciences have DPF as a very efficient tool for radiation tests of prospect materials and for improvement of their characteristics. In the field of broad-band current applications some results obtained in the fields of radiation material sciences, radiobiology, nuclear medicine, express Neutron Activation Analysis (including a single-shot interrogation of hidden illegal objects), dynamic non-destructive quality control, X-Ray microlithography and micromachining, and micro-radiography are presented. As the examples of the potential future applications it is proposed to use DPF as a powerful high-flux neutron source to generate very powerful pulses of neutrons in the nanosecond (ns) range of its duration for innovative experiments in nuclear physics, for the goals of radiation treatment of malignant tumors, for neutron tests of materials of the first wall, blankets and NFP device's constructions (with fluences up to 1 dpa per a year term), and ns pulses of fast electrons, neutrons and hard X-Rays for brachytherapy.

  17. Current and Suggested focus on Sustainability in Pyrometallurgy

    See, J. B.; Robertson, D. G. C.; Mackey, P. J.

    The production of iron and steel and non-ferrous metals by pyrometallurgical processes will remain a critical element in meeting the demand for materials in both developed and developing nations. Given the important need to reduce and minimise greenhouse gas emissions the technological focus of future pyrometallurgical R&D by universities and industry alike must concentrate on sustainability issues such as improved energy efficiency, recycling and waste minimization. Continued efforts are also needed on process optimization and new process development with a view to reducing capital and operating costs of the new large "mega" plants. Using the academic and industrial backgrounds of the authors, the present paper reviews the current status of R&D in pyrometallurgy in university departments with a particular emphasis on sustainability issues. The role of industry and government laboratories is also reviewed although primarily for developed countries. The paper also includes comments and suggestions on the future requirements for education and R&D in pyrometallurgy in developed countries to maximise sustainability. It is also suggested that future R&D in pyrometallurgy will be even more concentrated in developing countries — most notably China.

  18. Regulatory focus and work-related outcomes: a review and meta-analysis.

    Regulatory focus theory (Higgins, 1997) has received growing attention in organizational psychology, necessitating a quantitative review that synthesizes its effects on important criteria. In addition, there is need for theoretical integration of regulatory focus theory with personality research. Theoretical integration is particularly relevant, since personality traits and dispositions are distal factors that are unlikely to have direct effects on work behaviors, yet they may have indirect effects via regulatory focus. The current meta-analysis introduces an integrative framework in which the effects of personality on work behaviors are best understood when considered in conjunction with more proximal motivational processes such as regulatory focus. Using a distal-proximal approach, we identify personality antecedents and work-related consequences of regulatory foci in a framework that considers both general and work-specific regulatory foci as proximal motivational processes. We present meta-analytic results for relations of regulatory focus with its antecedents (approach and avoid temperaments, conscientiousness, openness to experience, agreeableness, self-esteem, and self-efficacy) and its consequences (work behaviors and attitudes). In addition to estimates of bivariate relationships, we support a meta-analytic path model in which distal personality traits relate to work behaviors via the mediating effects of general and work-specific regulatory focus. Results from tests of incremental and relative validity indicated that regulatory foci predict unique variance in work behaviors after controlling for established personality, motivation, and attitudinal predictors. Consistent with regulatory focus theory and our integrative theoretical framework, regulatory focus has meaningful relations with work outcomes and is not redundant with other individual difference variables.

    The growing shortage of nursing faculty and the need for faculty to teach doctoral students to address the shortage call for examination of factors that may contribute to the shortage, including those that are potentially modifiable, including work-life balance.This descriptive study examined work-life balance of a national sample of nursing faculty teaching in research-focused and practice-focused doctoral programs. Data were collected through an online survey of 554 doctoral program faculty members to identify their perceptions of work-life balance and predictors of work-life balance. Work-life balance scores indicated better work-life balance than expected. Factors associated with good work-life balance included higher academic rank, having tenure, older age, years in education, current faculty position, and no involvement in clinical practice. Current faculty position was the best predictor of work-life balance. Although work-life balance was viewed positively by study participants, efforts are needed to strengthen factors related to positive work/life in view of the increasing workload of doctoral faculty as the numbers of doctoral students increase and the number of seasoned faculty decrease with anticipated waves of retirements.

    In this work, an auto-focus actuator moving lens in mobile phone cameras is developed by applying a rotary VCM (voice coil motor). A novel inclined cam structure is used to convert the rotational motion by the VCM by into the linear motion of the focusing lens. The new focusing design enables the zero holding current required to maintain the lens module in the focusing position as well as the reduction of the module thickness. This paper presents the theoretical analysis and optimal design for the VCM actuator, cam structure and preload spring. We manufacture a prototype module with the size of 9.9x9.9x5.9 mm(3). The experimental results agree with the theoretical predictions and meet the required specifications for mobile camera applications.

    The Prime Focus Spectrograph (PFS) is a new optical/near-infrared multi-fiber spectrograph design for the prime focus of the 8.2m Subaru telescope. PFS will cover 1.3 degree diameter field with 2394 fibers to complement the imaging capability of Hyper SuprimeCam (HSC). The prime focus unit of PFS called Prime Focus Instrument (PFI) provides the interface with the top structure of Subaru telescope and also accommodates the optical bench in which Cobra fiber positioners are located. In addition, the acquisition and guiding cameras (AGCs), the optical fiber positioner system, the cable wrapper, the fiducial fibers, illuminator, and viewer, the field element, and the telemetry system are located inside the PFI. The mechanical structure of the PFI was designed with special care such that its deflections sufficiently match those of the HSC's Wide Field Corrector (WFC) so the fibers will stay on targets over the course of the observations within the required accuracy. In this report, the latest status of PFI develop...

    To determine which areas of professional billing present the highest risk to your practice, it is recommended that physicians and their office staff review the Office of Inspector General's (OIG) annual Work Plan. The Work Plan details areas for increased scrutiny by the federal government due to a high rate of inappropriate billing, which has cost the Medicare program millions of dollars. The OIG's Work Plan for Fiscal Year 2006 identifies several new areas of investigation, but what is more curious is what is not on the OIG Work Plan for 2006. For the first time in several years, this year's Work Plan does not include investigations into evaluation and management services (E/M), including the controversial consultation codes. But don't let your guard down on E/M documentation as our local Medicare carrier has stated they will begin a widespread probe review into the hospital admit CPT code 99222. Documentation to support the billing of CPT 99222 must include a comprehensive history (including ten review of systems); a comprehensive examination of eight or more organ systems for the 1995 guidelines or two elements from each of nine systems of a 1997 multisystem exam; and moderate decision making. Medicare will also be requesting reviews on subsequent inpatient hospital care codes, CPT 99231, 99232 and 99233.

    2017-07-27

    Working memory has long been thought to be closely related to consciousness. However, recent empirical studies show that unconscious content may be maintained within working memory and that complex cognitive computations may be performed on-line. This promotes research on the exact relationships between consciousness and working memory. Current evidence for working memory being a conscious as well as an unconscious process is reviewed. Consciousness is shown to be considered a subset of working memory by major current theories of working memory. Evidence for unconscious elements in working memory is shown to come from visual masking and attentional blink paradigms, and from the studies of implicit working memory. It is concluded that more research is needed to explicate the relationship between consciousness and working memory. Future research directions regarding the relationship between consciousness and working memory are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    Burnett, Bill

    People have been curious about offshore springs and seeps since at least the days of the Romans. In spite of many centuries of both casual and serious observations, there has been relatively little scientific study concerning the magnitude and effects of groundwater flow into the sea. Rather, studies were performed mostly to address water resource issues. Investigations over the past decade or so have now shown that groundwater discharge, at least in some cases, may be important for geochemical budgets and ecological effects.The Scientific Committee on Oceanic Research (SCOR) and the Land-Ocean Interactions in the Coastal Zone (LOICZ) Project of the International Geosphere-Biosphere Program have recently established a working group of experts to examine questions relating specifically to groundwater discharge in the coastal zone. Direct groundwater flow into the ocean is known to occur as springs and seeps in near-shore areas in many parts of the world. Submarine springs, for example, are well known off both coasts of Florida; Mexico's Yucatan Peninsula; in several areas around the Pacific rim including Chile, Hawaii, Guam, American Samoa, and Australia; in the Persian Gulf near Bahrain; in the Mediterranean Sea off Spain, France, Italy, Greece, Syria, Lebanon, Israel, and Libya; and in many other locations.

    2017-09-01

    Objectives This study aimed to evaluate the effect of a stress management intervention (SMI) on lasting return to work (RTW) among patients with work-related stress complaints. Methods Sickness benefit departments from three local municipalities referred patients on sick leave with work-related adjustment disorders or mild depression to the Department of Occupational Medicine, Regional Hospital West Jutland. A 2× randomization procedure allocated patients into one of three groups: intervention (N=58), control A (which received a clinical assessment; N=56), or control B (no assessment; N=49). Treatment comprised individual work-focused cognitive behavioral therapy (CBT) with an optional workplace intervention. The outcome was time until lasting RTW (16 and 44 weeks follow-up) using register data. Results Median number of weeks until lasting RTW was 15, 19, and 32 for the intervention group, control A, and control B respectively. However, for group B, clinical assessment was not part of the inclusion process, which may have introduced selection bias. In the fully-adjusted Cox regression model, the intervention group exhibited significantly faster lasting RTW at 44 weeks; hazard ratio (HR) 1.57 [95% confidence interval (95% CI) 1.01-2.44] relative to control group A, with a non-significant trend evident at 16 weeks; HR 1.70 (95% CI 0.94-3.10), when controlling for age, gender, occupation, sick leave during previous year, full or partial sick leave, and diagnosis. Unadjusted analyses remained directionally consistent but were reduced to marginal significance. Conclusions There was a tendency towards faster lasting RTW in the intervention group compared to control A, which received clinical assessment, in all analyses. The intervention group returned to work about 4 weeks earlier than control A, which could translate into substantial financial gains.

    Health and work are complex processes. Besides, they are multiple considering the forms they take. These two processes are linked to each other and they are influenced by each other. According to this, it is possible to establish that work world is extremely complex and heterogeneous. In this world, "old" or traditional risks coexist with "modern risks", derived from the new models of work organization and the incorporation of new technologies. Unemployment, work relationships precariousness and work risks outsourcing are results of neoliberal strategies. Some negative results of health-sickness process derived from transformation in work world and current global economic crisis have been noticed in current work conditions. Finally, the need for reconstructing policies focusing on this situation derived from work world is suggested.

    Full Text Available Background: Upper extremity injured workers are an under-studied population. A descriptive comparison of workers with shoulder, elbow and hand injuries reporting to a Canadian Workplace Safety and Insurance Board (WSIB clinic was undertaken.Objective: To determine if differences existed between injury groups stratified by current work status.Methods: All WSIB claimants reporting to our upper extremity clinic between 2003 and 2008 were approached to participate in this descriptive study. 314 working and 146 non-working WSIB claimants completed the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH; Short Form health survey (SF36; Worker’s Limitations Questionnaire and the Work Instability Scale. Various parametric and non-parametric analyses were used to assess significant differences between groups on demographic, work and health related variables.Results: Hand, followed by the shoulder and elbow were the most common site of injury. Most non-workers listed their current injury as the reason for being off work, and attempted to return to work once since their injury occurrence. Non-workers and a subset of workers at high risk for work loss showed significantly worse mental functioning. Workers identified physical demands as the most frequent injury-related on the job limitation. 60% of current workers were listed as low risk for work loss on the Work Instability Scale.Conclusions: Poorer mental functioning, being female and sustaining a shoulder injury were risk factors for work instability. Our cohort of injured non-workers were unable to return to work due to their current injury, reinforcing the need to advocate for modified duties, shorter hours and a work environment where stress and injury recurrence is reduced. Future studies examining pre-injury depression as a risk factor for prolonged work absences are warranted.

    2012-01-01

    Full Text Available Persons with severe mental illness (SMI have reduced workforce participation, which leads to significant economic and social disadvantage. This theoretical review introduces the strategies that have been implemented to address this issue. These include Individual Placement and Support (IPS services, the most widely researched form of supported employment, to which cognitive remediation has more recently been recognised in the USA, as an intervention to improve employment outcomes by addressing the cognitive impairments often experienced by people with SMI. The authors review the international literature and discuss specifically the Australian context. They suggest that Australia is in a prime position to engage clients in such a dual intervention, having had recent success with increasing access to supported employment programs and workforce reentry, through implementation of the Health Optimisation Program for Employment (HOPE. Such programs assist with gaining and maintaining employment. However, they do not address the cognitive issues that often prevent persons with SMI from effectively participating in work. Thus, optimising current interventions, with work-focused cognitive skills development is critical to enhancing employment rates that remain low for persons with SMI.

    Sounding rocket observations in the southern part of Japan suggest that the electron temperature profile occasionally exhibits the local increase by several hundred K at 100-110 km altitudes at 1100-1200 LT in winter. Detailed study of the temperature profiles indicates that such an increase is closely related to the existence of Sq current focus, because it becomes more significant when the measurement is made near the center of Sq focus. In order to understand a general feature of this unusual phenomena occurring in the Sq current focus, the sounding rocket experiment was conducted in Uchinoura of Japan. In this experiment, we launched "S-310-37" rocket equipped with a total of eight science instruments at 11:20 JST on January 16, 2007 after being convinced that the Sq current was approaching to the planned rocket trajectory. The geomagnetic activity had been successively quiet on that day so that we can estimate the position of Sq current focus. Our analysis of the obtained data indicates that the electron temperature was certainly increased by about 500-600 K at the altitude of 97-101 km with respect to the background. Strong electron density perturbation was also observed to exist above 97 km altitude, which corresponds to the lower boundary of the high electron temperatures. It is also noticeable that both the electric field and magnetic field data include unusual variation in the same altitude region as the temperature increase was observed, suggesting a possible connection between the thermal electron heating and variation of the electric and/or magnetic field. Thus, the first experiment in 2007 revealed a general feature of such unusual phenomena in the Sq current focus, and thereby our interest to the generation mechanism for increasing the electron temperature was more and more increased. We will conduct the second rocket experiment to investigate such unusual phenomena in the Sq current focus in January 2016. In this experiment, we will try to measure

    Whether they're guiding an unmanned aerial vehicle into a volcanic plume to sample aerosols, or documenting core drilling at a frozen lake in Siberia formed 3.6 million years ago by a massive meteorite impact, Arctic scientists are using video to enhance and expand their science and science outreach. FrontierScientists (FS), a forum for showcasing scientific work, produces and promotes radically different video blogs featuring Arctic scientists. Three- to seven- minute multimedia vlogs help deconstruct researcher's efforts and disseminate stories, communicating scientific discoveries to our increasingly connected world. The videos cover a wide range of current field work being performed in the Arctic. All videos are freely available to view or download from the FrontierScientists.com website, accessible via any internet browser or via the FrontierScientists app. FS' filming process fosters a close collaboration between the scientist and the media maker. Film creation helps scientists reach out to the public, communicate the relevance of their scientific findings, and craft a discussion. Videos keep audience tuned in; combining field footage, pictures, audio, and graphics with a verbal explanation helps illustrate ideas, allowing one video to reach people with different learning strategies. The scientists' stories are highlighted through social media platforms online. Vlogs grant scientists a voice, letting them illustrate their own work while ensuring accuracy. Each scientific topic on FS has its own project page where easy-to-navigate videos are featured prominently. Video sets focus on different aspects of a researcher's work or follow one of their projects into the field. We help the scientist slip the answers to their five most-asked questions into the casual script in layman's terms in order to free the viewers' minds to focus on new concepts. Videos are accompanied by written blogs intended to systematically demystify related facts so the scientists can focus

    McMillin, Stephen Edward

    2014-01-01

    Management of the dissemination of effective interventions in social work is often uncertain, and even when attention is paid to diffusing effective, innovative interventions, the focus is often disproportionately on a marketplace orientation of increasing the market share of branded, manualized interventions and social service treatment products. Public health frameworks of dissemination can improve knowledge translation in social interventions by focusing dissemination efforts on achieving equity and increasing the availability of effective interventions to all those who can benefit from them rather than simply focusing on commercial processes. This article identifies three equity-focused translation frameworks that can aid the dissemination of effective social interventions at the macro-, meso-, and micro-levels. Implications for policy and practice are discussed.

  8. "The current status of work on the origin of life"

    CERN Document Server

    CERN. Geneva

    2011-01-01

    Work on the Origin of Life is poised to converge onto a fourth phase and, many of us hope, success. The first phase concerned prebiotic synthesis of the small molecules, amino acids, nucleotides, lipids and others, essential for life and spanned some forty years. The second overlapping phase was inspired by the symmetric of the DNA or RNA double helix, presumed that life must necessarily be based on some form of template replication of one strand by ligation of free nucleotides to create the second strand, melting of the two strands and cycling again. Spearheaded by L. Orgel, but with many others, this effort has, to date, failed. The third phase begins with the discovery that RNA molecules can act as enzymes, and posited the RNA world, in which RNA molecules dominated. This has led to slightly successful efforts to evolve an RNA sequence able to template replicate itself. Current success is an evolved ribozyme able to do so for 14 nucleotides. The forth phase is converging around four ideas: 1) liposomes, h...

    In the near future, workforces will increasingly consist of older workers. At the same time, research has demonstrated that work-related growth motives decrease with age. Although this finding is consistent with life span theories, such as the selection optimization and compensation (SOC) model, we know relatively little about the process variables that bring about this change in work motivation. Therefore, we use a 4-wave study design to examine the mediating role of future time perspective and promotion focus in the negative association between age and work-related growth motives. Consistent with the SOC model, we found that future time perspective was negatively associated with age, which, in turn, was associated with lower promotion focus, lower work-related growth motive strength, and lower motivation to continue working. These findings have important theoretical implications for the literature on aging and work motivation, and practical implications for how to motivate older workers.

    2014-03-01

    Social work holds a unique place relative to other professions in that it prioritizes the elimination of human suffering as its primary goal. The roots of the profession are firmly planted in Western theories, historically and culturally specific perspectives, and knowledge. History has repeatedly demonstrated an association between the arrival of Westerners and the subsequent control of natural resources. Some argue that the development of global social work practice has serious pitfalls, including diverting needed resources away from local contexts and inadvertently spreading western world-views, paradigms and practices. However, the social work profession is uniquely positioned to offer expertise and collaborate with those experiencing the serious consequences of social inequity and the dearth of economic and social resources locally and across the globe. Grounded in anti-oppressive theory, guided by the difficult, yet acute awareness of western privilege and racism, and drawing from social/collective action and collaborative paradigms, a bi-directional exchange and action are detailed as the foundations for globally focused social work. The skills and knowledge base for global social work are essential as populations locally and worldwide are impacted by a global economic system that innately increases serious social inequity. Comprehensive training and preparation for globally focused social work, critical to successful engagement in global practice are outlined.

  11. Description of plasma focus current sheath as the Turner relaxed state of a Hall magnetofluid

    Science.gov (United States)

    Auluck, S. K. H.

    2009-12-01

    The central mystery of plasma focus research is the two orders-of-magnitude-higher-than-thermal fusion reaction rate and the fact that both the space-resolved neutron spectra and space-resolved reaction proton spectra show features which can be ascribed only to a rotational motion of the center-of-mass of the reacting deuteron population. It has been suggested earlier [S. K. H. Auluck, IEEE Trans. Plasma Sci. 25, 37 (1997)] that this and other experimental observations can be consistently explained in terms of a hypothesis involving rotation of the current carrying plasma annulus behind the imploding gas-dynamic shock. Such rotation (more generally, mass flow) is an in-built feature of relaxed state of a two-fluid plasma [R. N. Sudan, Phys. Rev. Lett. 42, 1277 (1979)]. Relaxation in the "Hall magnetofluid" approximation, in which the generalized Ohm's law includes the Hall effect term and the magnetic convection term but omits the contributions to the electric field from resistive dissipation, electron pressure gradient, thermoelectric effect, electron inertia, etc., has been extensively studied by many authors. In the present paper, Turner's [IEEE Trans. Plasma Sci. PS-14, 849 (1986)] degenerate solution for the relaxed state of the Hall magnetohydrodynamic plasma has been adapted to the case of an infinitely long annular current carrying plasma, a tractable idealization of the current sheath of a plasma focus. The resulting model is consistent with experimental values of ion kinetic energy and observation of predominantly radially directed neutron emission in good shots.

    The shape of the plasma current sheath (PCS) in the final stage of its radial compression, the dynamics of pinching, and the subsequent pinch decay in plasma focus (PF) discharges in different gases are studied using an improved multichannel system of electron-optical plasma photography and a newly elaborated synchronization system. The PCS structure in discharges in heavy gases (Ne, Ar) is found to differ significantly from that in discharges in hydrogen and deuterium. The influence of a heavy gas (Xe) additive to hydrogen and deuterium on the structure and compression dynamics of the PCS is investigated.

    Full Text Available Aim. To explore what strategies the supervisors found beneficial to prevent or reduce sickness absence among employees with musculoskeletal complaints. Methods. Five focus groups were conducted and 26 supervisors from health and social sector participated. Commonly used strategies to prevent sickness absence and interdisciplinary cooperation in this work were discussed in the focus groups. Systematic text condensation was used to analyse the data. Results. The supervisors described five strategies for sick leave management: (1 promoting well-being and a healthy working environment, (2 providing early support and adjustments, (3 making employees more responsible, (4 using confrontational strategies in relation to employees on long-term sick leave, and (5 cooperation with general practitioners (GPs. Conclusions. Strategies of promoting a healthy working environment and facilitating early return to work were utilised in the follow-up of employees with musculoskeletal complaints. Supportive strategies were found most useful especially in the early phases, while finding a balance between being supportive, on one side, and confronting the employee, on the other, was endeavoured in cases of recurrent or long-term sick leave. Further, the supervisors requested a closer cooperation with the GPs, which they believed would facilitate return to work.

    2015-05-01

    Working memory updating (WMU) tasks require different elements in working memory (WM) to be maintained simultaneously, accessing one of these elements, and substituting its content. This study examined possible developmental changes from childhood to adulthood both in focus switching and substituting information in WM. In addition, possible age-related changes in interference due to representational overlap between the different elements simultaneously held in these tasks were examined. Children (8- and 11-year-olds), adolescents (14-year-olds) and younger adults (mean age=22 years) were administered a numerical updating memory task, in which updating and focus switching were manipulated. As expected, response times decreased and recall performance increased with age. More importantly, the time needed for focus switching was longer in children than in adolescents and younger adults. On the other hand, substitution of information and interference due to representational overlap were not affected by age. These results suggest that age-related changes in focus switching might mediate developmental changes in WMU performance.

    2016-11-01

    Full Text Available This paper proposes a novel flux focusing magnetically geared (MG machine for wind power generation, considering the permanent magnets (PMs eddy current loss and the balance between the pull-out torque of MG machine and the back-electromotive force (EMFof the PM brushless machine. The PM eddy current loss in the two rotors of the conventional surface-mounted MG machine is calculated and analyzed by using finite-element method. By adopting serial-spoke structure in the inner rotor, a novel rotor structure for a MG machine is proposed to reduce the PM eddy current loss. Moreover, in order to balance the pull-out torque and the back-EMF, several serial-spoke structures and the main design parameters are investigated. Then, a quantitative comparison between the proposed topology and the conventional surface-mounted MG machine is performed. The analysis results indicate that the PM eddy current loss of the proposed MG machine can be significantly reduced and its pull-out torque and back-EMF can be balanced well.

    Full Text Available Complex systems development requires different ways of working than largely used static process oriented work. In practice, workers invent new ways of working to deal with appearing challenges. Thus, a company’s processes and tools should support these new process paths. Instead of defining a specific flow to conduct the work, several options for work processes should be allowed. This paper introduced the main findings of a case study conducted in a complex product development environment. The goal of the case study was to improve the company’s process support, based on the results of semi-structured interviews and the viewpoints of cognitive approach. The paper points out that it is important to focus on the goals for the work than the actual process phases and task descriptions. As a result of the study, the concept of a Work Management System (WMS is proposed. The paper introduces this concept and discusses in details the main benefits of using a WMS.

    A superconducting strong-focusing cyclotron (SFC) is being developed for high-current applications. It incorporates four innovations. Superconducting quarter-wave cavities are used to provide >20 MV/turn acceleration. The orbit separation is thereby opened so that bunch-bunch interactions between successive orbits are eliminated. Quadrapole focusing channels are incorporated within the sectors so that alternating-gradient strong-focusing transport is maintained throughout. Dipole windings on the inner and outer orbits provide enhanced control for injection and extraction of bunches. Finally each sector magnet is configured as a flux-coupled stack of independent apertures, so that any desired number of independent cyclotrons can be integrated within a common footprint. Preliminary simulations indicate that each SFC should be capable of accelerating 10 mA CW to 800 MeV with very low loss and >50% energy efficiency. A primary motivation for SFC is as a proton driver for accelerator-driven subcritical fission in a molten salt core. The cores are fueled solely with the transuranics from spent nuclear fuel from a conventional nuclear power plant. The beams from one SFC stack would destroy all of the transuranics and long-lived fission products that are produced by a GWe reactor [1]. This capability offers the opportunity to close the nuclear fuel cycle and provide a path to green nuclear energy.

    To develop tools offering definite orientation for managers and employees to support their work improvement through occupational mental health. This research was a part of the Mental Health Improvement & Reinforcement Study (MIR study), conducted from October 2004 to March 2006. We developed a trial version named the Kaizen Check List (KCL) by referring to problem solving methods for quality management. Then we improved it for a formal version named MIR Research of Recognition (MIRROR). A feedback form named MIR Action Guidance (MIRAGe) was also developed. We analyzed data from 1,953 respondents at five manufacturing enterprises in Japan using MIRROR and the Brief Job Stress Questionnaire (BJSQ) to determine whether or not the workers requesting work improvement had more stress than other workers. The KCL had 47 items, which indicated desirable working conditions for mental health at work, and four answer categories. MIRROR has 45 selected items and improved answer categories. MIRAGe displays the results of MIRROR and step-by-step guidance for work improvement. Respondents with request had significantly higher scores in stressor and lower scores in buffer factors compared with respondents without request in many items of MIRROR. A combinational use of MIRROR and stress scales is useful for finding worksites with high risk factors for mental health and for directing focus on work improvement at these worksites according to workers' requests.

One assumption is that the erosion of boundaries offers potential for increased employee control, meaning increased autonomy or self-determination at work (employee control how and when to do what. This assumption is supported by theories on the psychosocial working environment. Another assumption is that the erosion of boundaries threatens the frontiers from where employees can defend their interests, and consequently reduces employees’ control of their work (what and how much to do. This assumption is supported by “labor process theory.” This article studies control and the erosion of boundaries in two case factories in the food industry. Two perspectives are applied: the psychosocial working environment and “labor process theory.”

    Anecdotes from creative eminences suggest that executive control plays an important role in creativity, but scientific evidence is sparse. Invoking the Dual Pathway to Creativity Model, the authors hypothesize that working memory capacity (WMC) relates to creative performance because it enables persistent, focused, and systematic combining of elements and possibilities (persistence). Study 1 indeed showed that under cognitive load, participants performed worse on a creative insight task. Study 2 revealed positive associations between time-on-task and creativity among individuals high but not low in WMC, even after controlling for general intelligence. Study 3 revealed that across trials, semiprofessional cellists performed increasingly more creative improvisations when they had high rather than low WMC. Study 4 showed that WMC predicts original ideation because it allows persistent (rather than flexible) processing. The authors conclude that WMC benefits creativity because it enables the individual to maintain attention focused on the task and prevents undesirable mind wandering.

    The Heavy Ion Fusion (HIF) program is progressing through a series of physics and technology demonstrations leading to an inertial fusion power plant. The High Current Experiment (HCX) at Lawrence Berkeley National Laboratory is exploring the physics of intense beams with high line-charge density. Superconducting focusing quadrupoles have been developed for the HCX magnetic transport studies. A baseline design was selected following several pre-series models. Optimization of the baseline design led to the development of a first prototype that achieved a conductor-limited gradient of 132 T/m in a 70 mm bore, without training, with measured field errors at the 0.1% level. Based on these results, the magnet geometry and fabrication procedures were adjusted to improve the field quality. These modifications were implemented in a second prototype. In this paper, the optimized design is presented and comparisons between the design harmonics and magnetic measurements performed on the new prototype are discussed.

    At the output of a laser ion source, a high current of highly charged ions with a large range of charge states is available. The focusing of such a beam by magnetic elements causes a nonlinear space-charge field to develop which can induce large aberrations and emittance growth in the beam. Simulation of the beam from the CERN laser ion source will be presented for an ideal magnetic and electrostatic system using a radially symmetric model. In addition, the three dimensional software KOBRA3 is used for the simulation of the solenoid line. The results of these simulations will be compared with experiments performed on the CERN laser ion source with solenoids (resulting in a hollow beam) and a series of gridded electrostatic lenses.

    Full Text Available Historically, democratic and participatory processes in the Brazilian society, and specifically in school, have been permeated by intermittences, weaknesses and resistances caused by multiple determinations. The text focuses on aspects concerningthe organization of education work through two lines of analysis: the first angle refers to the social constructs of structural and organic nature linked to relations of power andanti-democratic practices of the society in general. The second angle reference to a kindof ethnographic research, conducted within a public school in the Minas Gerais state. We seek to grasp the challenges on building practices and strategies in support of the participatory processes of the school community in the pedagogic project design and in the operation of the school board. We propose, with these analyses, to contribute withreflections on the status of teachers, as a subject, in the school organization throughconnections with work activities related to their everyday practice.

    2015-12-01

    Chronic rhinosinusitis (CRS) affects more than 10% of the population in the United States and Europe. Recent findings point to a considerable variation of inflammatory subtypes in patients with CRS with nasal polyps and patients with CRS without nasal polyps. According to current guidelines, glucocorticosteroids and antibiotics are the principle pharmacotherapeutic approaches; however, they fail in a group of patients who share common clinical and laboratory markers. Several clinical phenotypes often leading to uncontrolled disease, including adult nasal polyposis, aspirin-exacerbated respiratory disease, and allergic fungal rhinosinusitis, are characterized by a common endotype: a TH2 bias is associated with a higher likelihood of comorbid asthma and recurrence after surgical treatment. As a consequence, several innovative approaches targeting the TH2 bias with humanized mAbs have been subjected to proof-of-concept studies in patients with CRS with nasal polyps with or without comorbid asthma: omalizumab, reslizumab, mepolizumab, and recently dupilumab. Future concepts using upstream targets, such as GATA-3, also focus on this endotype. This current development might result in advantages in the treatment of patients with the most severe CRS.

    The plasma current can be driven solely by injecting electron cyclotron waves (ECWs) in spherical tokamak (ST) configuration. A system of 28 GHz gyrotron (maximum power: 270 kW) is renewed and reinstalled on QUEST. A focused ECW beam, whose diameter is about 5 cm at the second harmonic resonance, is injected for local ECW heating and current drive. The local power density at resonance exceeds 75 MW/m2 at an injection power of 150 kW. The incident ECW polarization can be adjusted employing the phase shifter consisting of two corrugated plates. During 1.25 second pulse of ECH, plasma current is built up to Ip = 70 kA fully non-inductively with a core electron density of ne > 1018 m-3. The closed flux in such ST plasma is determined at the inboard limiter on the center stack. Energetic electrons are also responsible for the pressure and equilibrium.

  16. Shift Work and Health: Current Problems and Preventive Actions

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available The paper gives an overview of the problems to be tackled nowadays by occupational health with regards to shift work as well as the main guidelines at organizational and medical levels on how to protect workers’ health and well-being. Working time organization is becoming a key factor on account of new technologies, market globalization, economic competition, and extension of social services to general populations, all of which involve more and more people in continuous assistance and control of work processes over the 24 hours in a day. The large increase of epidemiological and clinical studies on this issue document the severity of this risk factor on human health and well being, at both social and psychophysical levels, starting from a disruption of biological circadian rhythms and sleep/wake cycle and ending in several psychosomatic troubles and disorders, likely also including cancer, and extending to impairment of performance efficiency as well as family and social life. Appropriate interventions on the organization of shift schedules according to ergonomic criteria and careful health surveillance and social support for shift workers are important preventive and corrective measures that allow people to keep working without significant health impairment.

    The modern primary healthcare workforce needs to be resilient. Early research framed professional resilience as avoiding 'burnout'; however, more recent literature has introduced the concept of positive adaptation to professional challenges, which results in individuals thriving in their role. To explore what primary health professionals working in challenging environments consider to be characteristics of resilience and what promotes or challenges professional resilience. A qualitative focus group in north east Scotland. Five focus groups were held with 20 health professionals (six GPs, nine nurses, four pharmacists, and a practice manager) based in rural or deprived city areas in the north east of Scotland. Inductive thematic analysis identified emerging themes. Personal resilience characteristics identified were optimism, flexibility and adaptability, initiative, tolerance, organisational skills, being a team worker, keeping within professional boundaries, assertiveness, humour, and a sense of self-worth. Workplace challenges were workload, information overload, time pressures, poor communication, challenging patients, and environmental factors (rural location). Promoters of professional resilience were strong management support, teamwork, workplace buffers, and social factors such as friends, family, and leisure activities. A model of health professional resilience is proposed that concurs with existing literature but adds the concept of personal traits being synergistic with workplace features and social networks. These facilitate adaptability and enable individual health professionals to cope with adversity that is inevitably part of the everyday experience of those working in challenging healthcare environments. © British Journal of General Practice 2016.

    Fibromyalgia (FM) is a chronic medical condition characterized by physical, psychiatric and psychological symptoms. Widespread pain, fatigue, sleep disturbances, heightened sensitivity, morning stiffness, decreased volition, depressed mood and a history of early abuse are frequently reported by patients with FM. Treatment of fibromyalgia is multidisciplinary, with an emphasis on active patient participation, medications, cognitive-behavioral therapy and physical modalities. No single medication has yet been found to sufficiently control all the symptoms of FM; currently available medication classes include antidepressants, nonsteroidal anti-inflammatory drugs, opioids, sedatives, muscle relaxants, analgesics, hypnotic agents and anticonvulsants. Hence, treatment for patients with FM, including pharmacological and non-pharmacological approaches, should be individualized based on each patient's clinical history, target symptoms and functional impairments. Although nonpharmacological modalities are also frequently used, recent research has focused on identifying more effective pharmacological treatments, particularly antidepressants and anticonvulsants. Furthermore, several new pharmacological agents have been now officially approved for the treatment of patients with FM. Thus, the purpose of this review is to help healthcare professionals make informed decisions about the appropriate use of a number of pharmacological treatments for patients with FM.

    Advanced Practice Clinicians (APCs) in collaborative practice represent a diverse and valuable group of health care professionals, including nurse practitioners, physician assistants, nurse anesthetists, and nurse midwives. Because these healthcare professionals have been identified as part of the solution to physician shortages, it is critical for health networks to examine and address issues affecting collaborative relationships. We invited our network APCs to participate in focus group sessions to determine both attributes and barriers to an ideal work environment. Four major themes emerged: (1) compensation, (2) network representation, (3) employment structure, and (4) workplace culture. While issues relating to compensation and representation were prevalent, discussions also revealed the importance of relationships and communication. To ensure successful collaboration and, thereby, reduce clinician turnover, leaders must address gaps between the existing and ideal states in structural factors affecting job satisfaction (Themes 1-3) as well as the behavioral factors represented in workplace culture (Theme 4).

    The Catalina Sky Survey (CSS) continues to be the most productive Near Earth Object (NEO) survey in operation, accounting for nearly two-thirds of all NEO discoveries since 2005. We present a review of the current status of the survey operations, and highlight recent and future upgrades to our instrumentation. Recently, CSS has refurbished a 1.0-m telescope on Mt. Lemmon, Arizona, adjacent to the 1.5-m survey telescope. This telescope will be primarily used for NEO follow-up, recovery, and physical characterization of NEOs including colors and light curves. It will be capable of remote or robotic operations, programmed by adaptive queue-planning software of our own design. We expect to complete commissioning activities and begin full-time operations by the end of this year. A large-format camera featuring a single 10k x 10k detector is in the process of being fabricated for the 1.5-m survey telescope. The new camera system will increase the field-of-view from 1.2 to 5.0 square degrees, and the nightly coverage rate from 180 to 750 square degrees, to limiting magnitude V 21.5. This telescope is already the most productive for NEO discovery, accounting for approximately 40% of new NEOs since 2008, at an average rate of over 350 NEOs per year. We anticipate a significant increase in its discovery rate after commissioning, which will begin in late 2013.

    In 2010 Mr. Nagatsuma, the former Minister of the Ministry of Health, Labor and Welfare of Japan expressed his opinion that the health examination of work place should includes items to focus on mental disorders such as depression, just after the Japanese Society of Psychiatry and Neurology with related societies launched the Joint Declaration of Countermeasure for Depression. To carry out the examination the following requirement is necessary. 1) Keeping the results of the health examination in secret. 2) Enlightenment of mental disorders including depression, bipolar disorders, schizophrenia and pervasive developmental disorders. 3) Not only questionnaires for screening but also supportive and sympathetic interview methods that are reliable and valid. 4) Cooperation between work place and health professional In introduction of medical intervention and rehabilitation. The strategy to realize the above-mentioned requirements is as follows. 1) Education of the industrial mental health staff: public health nurses and psychologists. 2) Pilot study to examine the method of the health examination. 3) Research to establish the future preventive method of mental disrders. 4) Budgetary appropriation. As the health examination should be benefit for workers, hasty introduction of the examination should be avoided.

  2. Focused transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex modulates specific domains of self-regulation.

    2015-02-01

    Recent neuroscience theories suggest that different kinds of self-regulation may share a common psychobiological mechanism. However, empirical evidence for a domain general self-regulation mechanism is scarce. The aim of this study was to investigate whether focused anodal transcranial direct current stimulation (tDCS), facilitating the activity of the dorsolateral prefrontal cortex (dlPFC), acts on a domain general self-regulation mechanism and thus modulates both affective and appetitive self-regulation. Twenty smokers participated in this within-subject sham controlled study. Effects of anodal left, anodal right and sham tDCS over the dlPFC on affective picture appraisal and nicotine craving-cue appraisal were assessed. Anodal right tDCS over the dlPFC reduced negative affect in emotion appraisal, but neither modulated regulation of positive emotion appraisal nor of craving appraisal. Anodal left stimulation did not induce any significant effects. The results of our study show that domain specific self-regulation networks are at work in the prefrontal cortex. Focused tDCS modulation of this specific self-regulation network could probably be used during the first phase of nicotine abstinence, during which negative affect might easily result in relapse. These findings have implications for neuroscience models of self-regulation and are of relevance for the development of brain stimulation based treatment methods for neuropsychiatric disorders associated with self-regulation deficits.

    A Neutrino Factory based on a muon storage ring is the ultimate tool for studies of neutrino oscillations, including possibly the discovery of leptonic CP violation. it is also the first step toward a muon collider. To develop a stored-muon-beam facility to serve as a Neutrino Factory, it is necessary to ''cool'' a muon beam (decrease its phase-space volume). The short lifetime of the muon, 2.2 {micro}s at rest, eliminates all currently demonstrated cooling techniques and requires that a new, heretofore untried, technique--ionization cooling--be employed. Although ionization cooling of muons has never been demonstrated in practice, it has been shown by end-to-end simulation and design studies to be an important factor both for the performance and for the cost of a Neutrino Factory. This motivates an international program of R and D, including an experimental demonstration at Rutherford Appleton Laboratory (RAL). The aims of the international Muon Ionization Cooling Experiment are: (1) to show that it is possible to design, engineer and build a section of cooling channel capable of giving the desired performance for a Neutrino Factory; and (2) to place it in a muon beam and measure its performance in various modes of operation and beam conditions, thereby investigating the limits and practicality of cooling. The MICE collaboration has designed an experiment in which a section of an ionization cooling channel is exposed to a muon beam. This cooling channel assembles liquid-hydrogen absorbers providing energy loss and high-gradient radio frequency (RF) cavities to re-accelerate the particles, all tightly contained in a magnetic channel. It reduces the beam transverse emittance by > 10% for muon momenta between 140 and 240 MeV/c. The layout of the experiment is shown. They utilize one complete magnetic cell of the cooling channel, comprising three absorber-focus-coil (AFC) modules and two RF-coupling-coil (RFCC) modules. Spectrometers placed before

    While high-intensity focused ultrasound has been used for some time in the management of uterine fibroids, its effectiveness and safety in managing adenomyosis is less well established. A literature review was performed of all eligible reports using this modality as a treatment for adenomyosis. Relevant publications were obtained from the PubMed electronic database from inception through March 2016. Eleven articles, including information from 1,150 treatments and follow-up data from 990 patients, were reviewed. High-intensity focused ultrasound appears to be effective and safe in the management of symptomatic adenomyosis, and can be considered as an alternative uterine-sparing option for women with this condition.

    2015-07-01

    In healthcare, occupational groups have adopted tactics to maintain autonomy and control over their areas of work. Witz described a credentialist approach to occupational closure adopted by nursing in the United Kingdom during the 19th and early 20th centuries. However, the recent advancement of assistant, 'non-qualified' workers by governments and managers forms part of a reconfiguration of traditional professional work. This research used focus groups with three cohorts of healthcare support workers undertaking assistant practitioner training at a London university from 2011 to 13 (6 groups, n = 59). The aim was to examine how these workers positioned themselves as professionals and accounted for professional boundaries. A thematic analysis revealed a complex situation in which participants were divided between articulating an acceptance of a subordinate role within traditional occupational boundaries and a usurpatory stance towards these boundaries. Participants had usually been handpicked by managers and some were ambitious and confident in their abilities. Many aspired to train to be nurses claiming that they will gain recognition that they do not currently get but which they deserve. Their scope of practice is based upon their managers' or supervisors' perception of their individual aptitude rather than on a credentialist claim. They 'usurp' nurses claim to be the healthcare worker with privileged access to patients, saying they have taken over what nursing has considered its core work, while nurses abandon it for largely administrative roles. We conclude that the participants are the not unwilling agents of a managerially led project to reshape the workforce that cuts across existing occupational boundaries.

    Working memory (WM) is one of our core cognitive functions, allowing us to keep information in mind for shorter periods of time and then work with this information. It is the gateway that information has to pass in order to be processed consciously. A well-functioning WM is therefore crucial for a number of everyday activities including learning and academic performance (Gathercole et al., 2003; Bull et al., 2008), which is the focus of this review. Specifically, we will review the research investigating whether improving WM capacity using Cogmed WM training can lead to improvements on academic performance. Emphasis is given to reviewing the theoretical principles upon which such investigations rely, in particular the complex relation between WM and mathematical and reading abilities during development and how these are likely to be influenced by training. We suggest two possible routes in which training can influence academic performance, one through an effect on learning capacity which would thus be evident with time and education, and one through an immediate effect on performance on reading and mathematical tasks. Based on the theoretical complexity described we highlight some methodological issues that are important to take into consideration when designing and interpreting research on WM training and academic performance, but that are nonetheless often overlooked in the current research literature. Finally, we will provide some suggestions for future research for advancing the understanding of WM training and its potential role in supporting academic attainment.

    Transverse magnetic focusing properties of graphene using a ballistic four terminal structure are investigated. The electric response is obtained using the semiclassical billiard model. The transmission exhibits pronounced peaks as a consequence of skipping orbits at the edge of the structure. When we add a pn-junction between the two probes, snake states along the pn-interface appear. Injected electrons are guided by the pn-interface to one of the leads depending on the value of the applied magnetic field. Oscillations in the resistance are found depending on the amount of particles that end up in each lead.

    Full Text Available Abstract Alzheimer’s disease (AD is a neurodegenerative disorder that impairs mainly the memory and cognitive function in elderly. Extracellular beta amyloid deposition and intracellular tau hyperphosphorylation are the two pathological events that are thought to cause neuronal dysfunction in AD. Since the detailed mechanisms that underlie the pathogenesis of AD are still not clear, the current treatments are those drugs that can alleviate the symptoms of AD patients. Recent studies have indicated that these symptom-reliving drugs also have the ability of regulating amyloid precursor protein processing and tau phosphorylation. Thus the pharmacological mechanism of these drugs may be too simply-evaluated. This review summarizes the current status of AD therapy and some potential preclinical considerations that target beta amyloid and tau protein are also discussed.

  5. Current approaches of managing microbial diseases:focus on nanosciences technique

    2015-01-01

    Nanoscience is a fast growing research area that focuses on producing and utilizing nano-sized particles, which are measured in nanometers. Recently, nanoparticles are used in various fields. Therefore, studies on the effect of nanoparticles on microorganisms are worthy of analysis. However, using many antimicrobial agents has been avoided because of their methodical harmful effect. Hence, this review paper focuses on the use of some nanomaterials to manage microbial diseases. The discussed nanomaterials as antimicrobial agents include sliver nanoparticles, gold nanoparticles and copper nanoparticles. This review also explains the mechanisms of action of some nanotechnological products to inhibit microorganisms. There are many problems in the development of an evaluation for the effect of nanomaterials on environment. Nevertheless, the defect of the approaches used to analyze nanomaterials toxicity gives no ground for hampering the development of nanotechnologies for safety using. In order to overcome this problem, ecotoxicological studies should be extended to include the analysis of the biological safety of nanomaterials in environment and accumulate experimental data.

    The objective of the study was to identify factors related to the number of solution-focused brief therapy sessions required to solve adolescents' problems. The study was conducted at the foster care and health care institutions. The sample consisted of 73 adolescents (41% of males, 59% of females), aged 12 to 18 years, who achieved high level of therapeutic progress during solution-focused brief therapy. Respondents from foster care institutions made up 47% and from health care institutions--53%. The study design included: (1) an initial evaluation, where adolescents' psychosocial adjustment and personality traits were evaluated as well as information on demographic characteristics and type of referral for therapy was collected; (2) solution-focused brief therapy was carried out. In the first session, information on the type and severity of the problem presented for the therapy and motivation to solve the problem was collected; (3) the effectiveness of solution-focused brief therapy was evaluated. Standardized interview for the evaluation of psychosocial adjustment of adolescents was used to evaluate the difficulties of adolescents' psychosocial functioning. Eysenck Personality Questionnaire was administered to evaluate adolescents' personality traits. Therapist's evaluation of improvement was used to evaluate the effectiveness of solution-focused brief therapy. The analysis of results showed that 60.3% of adolescents needed two to three solution-focused brief therapy sessions to solve their problems. Lower number of sessions needed to achieve a solution was related to lower level of psychoticism, lower level of subjectively evaluated problem severity, and living with parents (as the opposite of living in foster care institutions). Ordinal regression analysis revealed that living with parents, self-referral to the therapy, lower level of subjectively evaluated problem severity, and higher self-confidence were significant predictors of lower number of sessions

    First described in 1959 by physicist Richard P Feynman, who saw it as an unavoidable development in the progress of science, nanotechnology has been part of mainstream scientific theory with potential medical and dental applications since the early 1990s. Nanoparticles, nanospheres, nanorods, nanotubes, nanofibers, dendrimers and other nanostructures have been studied for various applications to biologic tissues and systems. While many layers of nanotechnologic capability have been envisioned for oral health in the last decade (eg, oral hygiene maintenance, local anesthesia, even whole-tooth replacement), few of these applications have been developed. Part 1 of a three-part series reviews the current clinical utility of nanotechnology's most tangible contribution to dentistry to date: the restoration of tooth structure with nanocomposites. Characterized by filler-particle sizes of ≤100 nm, these materials can offer esthetic and strength advantages over conventional microfilled and hybrid resin-based composite (RBC) systems, primarily in terms of smoothness, polishability and precision of shade characterization, plus flexural strength and microhardness similar to those of the better-performing posterior RBCs. Available comparative data for nanocomposites and organically-modified ceramic (Ormocer(®)) restoratives are also reviewed. Finally, plausible "next-phase" trends in current nanorestorative research are judiciously examined, including 1) calcium-, phosphate-, and fluoride-ion-releasing nanocomposites for anticaries applications and 2) restorative systems based on biomimetic emulation of the nanomolecular assembly processes inherent in dental enamel formation using nanorods, nanospheres, and recombinant amelogenins.

    Across the country, new RHIOs are being formed every day. The 21 RHIOs studied by the work group illustrate the variety of purposes, funding, and record linking methods RHIOs may adopt. As this trend continues to evolve and improve, RHIOs may prove to be a valuable stepping stone on the road to a national system in which a patient's medical data will be available anywhere, anytime. Accurate patient identification and linking are the foundation of health technology that is implemented in a RHIO or any similar network that shares patient information. Without accurate patient identification, patient safety and quality of care are compromised. When high percentages of duplication or overlaying of records occurs in electronic health record databases, physician trust in the system is lost. As HIM professionals, we must be involved in addressing the security and confidentiality of RHIO databases and in defining the record linking method appropriate to the RHIO. As professionals skilled in patient identification methods and possessing significant organizational skills and personnel management experience, HIM professionals should become involved in this process at the earliest opportunity in the RHIO formation. HIM professionals can participate in long-term planning, business plan development, and organizational structure definition. Future articles will address how HIM professionals can become involved, what particular attributes and skills they can bring to the table, and job descriptions appropriate to HIM professionals in the healthcare information sharing industry. The work group urges all HIM professionals to become involved personally in this exciting new field.

    2016-01-01

    Loss of muscle mass arises from an imbalance of protein synthesis and protein degradation. Potential triggers of muscle wasting and function are immobilization, loss of appetite, dystrophies and chronic diseases as well as aging. All these conditions lead to increased morbidity and mortality in patients, which makes it a timely matter to find new biomarkers to get a fast clinical diagnosis and to develop new therapies. This mini-review covers current developments in the field of biomarkers and drugs on cachexia and sarcopenia. Here, we reported about promising markers, e.g. tartrate-resistant acid phosphatase 5a (TRACP5a), and novel substances like Epigallocatechin-3-gallate (EGCg). In summary, the progress to combat muscle wasting is in full swing and perhaps diagnosis of muscle atrophy and of course patient treatments could be soon supported by improved and more helpful strategies.

    2010-01-01

    Full Text Available Thienopyridines are a class of drug targeting the platelet adenosine diphosphate (ADP 2 receptor. They significantly reduce platelet activity and are therefore clinically beneficial in settings where platelet activation is a key pathophysiological feature, particularly myocardial infarction. Ticlopidine, the first of the class introduced to clinical practice, was soon challenged and almost completely replaced by clopidogrel for its better tolerability. More recently, prasugrel and ticagrelor have been shown to provide a more powerful antiplatelet action compared to clopidogrel but at a cost of higher risk of bleeding complications. Cangrelor, a molecule very similar to ticagrelor, is currently being evaluated against clopidogrel. Considering the key balance of ischemic protection and bleeding risk, this paper discusses the background to the development of prasugrel, ticagrelor, and cangrelor and aims to characterise their risk-benefit profile and possible implementation in daily practice.

    Complete surgical resection still remains the only possibility of curing pancreatic cancer,however,only 10% of patients undergo curative surgery.Pancreatic resection currently remains the only method of curing patients,and has a 5-year overall survival rate between 7%-34% compared to a median survival of 3-11 mo for unresected cancer.Pancreatic surgery is a technically demanding procedure requiring highly standardized surgical techniques.Nevertheless,even in experienced hands,perioperative morbidity rates (delayed gastric emptying,pancreatic fistula etc.) are as high as 50%.Different strategies to reduce postoperative morbidity,such as different techniques of gastroenteric reconstruction (pancreatico-jejunostomy vs pancreatico-gastrostomy),intraoperative placement of a pancreatic main duct stent or temporary sealing of the main pancreatic duct with fibrin glue have not led to a significant improvement in clinical outcome.The perioperative application of somatostatin or its analogues may decrease the incidence of pancreatic fistulas in cases with soft pancreatic tissue and a small main pancreatic duct (< 3 mm).The positive effects of external pancreatic main duct drainage and antecolic gastrointestinal reconstruction have been observed to decrease the rate of pancreatic fistulas and delayed gastric emptying,respectively.Currently,the concept of extended radical lymphad-enectomy has been found to be associated with higher perioperative morbidity,but without any positive impact on overall survival.However,there is growing evidence that portal vein resections can be performed with acceptable low perioperative morbidity and mortality but does not achieve a cure.

    2017-01-01

    RNA visualization is crucial in order to understand the relationship that exists between RNA structure and its function, as well as the development of better RNA structure prediction algorithms. However, in the context of RNA visualization, one key structure remains difficult to visualize: Pseudoknots. Pseudoknots occur in RNA folding when two secondary structural components form base-pairs between them. The three-dimensional nature of these components makes them challenging to visualize in two-dimensional media, such as print media or screens. In this review, we focus on the advancements that have been made in the field of RNA visualization in two-dimensional media in the past two decades. The review aims at presenting all relevant aspects of pseudoknot visualization. We start with an overview of several pseudoknotted structures and their relevance in RNA function. Next, we discuss the theoretical basis for RNA structural topology classification and present RNA classification systems for both pseudoknotted and non-pseudoknotted RNAs. Each description of RNA classification system is followed by a discussion of the software tools and algorithms developed to date to visualize RNA, comparing the different tools' strengths and shortcomings.

    The paper considers critical currents in A-15 structure Nb3Al converted from a cold-worked bcc structure. Nb3Al prepared in the ductile phase by quenching and mechanical working followed by conversion to the A-15 structure could carry currents above 10 to the 9th power A/sq m in fields near 20 T. These critical currents are comparable to those of Nb3Ge and V3Ga which are closest competing materials for use in high fields; further enhancement of the critical current is possible if thermal treatments are optimized.

    The emergency management of acute severe bleeding in trauma patients has changed significantly in recent years. In particular, greater attention is now being devoted to a prompt assessment of coagulation alterations, which allows for immediate haemostatic resuscitation procedures when necessary. The importance of an early trauma-induced coagulopathy (TIC) diagnosis has led physicians to increase the efforts to better understand the pathophysiological alterations observed in the haemostatic system after traumatic injuries. As yet, the knowledge of TIC is not exhaustive, and further studies are needed. The aim of this review is to gather all the currently available data and information in an attempt to gain a better understanding of TIC. A comprehensive literature search was performed using MEDLINE database. The bibliographies of relevant articles were screened for additional publications. In major traumas, coagulopathic bleeding stems from a complex interplay among haemostatic and inflammatory systems, and is characterized by a multifactorial dysfunction. In the abundance of biochemical and pathophysiological changes occurring after trauma, it is possible to discern endogenously induced primary predisposing conditions and exogenously induced secondary predisposing conditions. TIC remains one of the most diagnostically and therapeutically challenging condition.

  6. Biotechnological Utilization with a Focus on Anaerobic Treatment of Cheese Whey: Current Status and Prospects

    Directory of Open Access Journals (Sweden)

    Aspasia A. Chatzipaschali

    2012-09-01

    Full Text Available Cheese whey utilization is of major concern nowadays. Its high organic matter content, in combination with the high volumes produced and limited treatment options make cheese whey a serious environmental problem. However, the potential production of biogas (methane, hydrogen or other marketable products with a simultaneous high COD reduction through appropriate treatment proves that cheese whey must be considered as an energy resource rather than a pollutant. The presence of biodegradable components in the cheese whey coupled with the advantages of anaerobic digestion processes over other treatment methods makes anaerobic digestion an attractive and suitable treatment option. This paper intends to review the most representative applications of anaerobic treatment of cheese whey currently being exploited and under research. Moreover, an effort has been made to categorize the common characteristics of the various research efforts and find a comparative basis, as far as their results are concerned.

    Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a large and very diverse group of neoplasms. Clinical presentation of NETs depends on the site of the primary tumor and whether the tumor is functioning (i.e., secreting peptides or neuroamines that produce symptoms). The diagnosis of GEP-NET is further complicated by symptomatic differences that occur depending on the type of secreted peptide or neuroamine. Due to their heterogeneity and unique characteristics, early diagnosis of GEP-NETs is difficult, which increases the likelihood of metastatic disease and reduces the scope of therapeutic possibilities. Thus, a multidisciplinary approach for the treatment of GEP-NETs is necessary. This review is the result of presentations that were delivered during an expert meeting on the treatment of GEP-NETs supported by Ipsen. We summarize the current knowledge on the epidemiology, incidence, diagnosis, and treatment of GEP-NETs. We examined the role of the somatostatin analog (SSA) lanreotide and the impact of the data from the recently published, randomized, double-blind, placebo-controlled CLARINET study (Controlled study of Lanreotide Antiproliferative Response In Neuroendocrine Tumors) on disease management. We also review the recent treatment options and recommendations for GEP-NETs.

    It is estimated that employers spend more than 75 billion dollars annually on obesity-attributable health care. Interventions to reduce or prevent the risk of obesity are increasingly common at worksites and include health fairs, weight loss and nutrition classes, and fitness programs. However, many companies lack the resources to plan and implement these types of programs. Environmental approaches offer companies a low-cost option. A community-based participatory research model was used to bring academic researchers, human resources personnel, and health department educators together to plan and implement an environmental program aimed at increasing healthy eating and physical activity at four small manufacturing companies. The Diffusion of Innovations Theory guided the development of focus group questions. A focus group study was then conducted to gather information from employees and managers at these four companies. The questions identified workplace strategies that would aid in reducing barriers and developing appropriate communication channels to enhance employee participation in the program. The researchers identified themes from manager and employee focus groups regarding the following five environmental components: signs, walking paths, food changes, educational strategies, and advisory groups.

    Full Text Available Background — The presence of chronic hard-to-heal wounds significantly affects patients’ quality of life causing pain, discomfort, decrease of mobility and consequently leads to social isolation and depression. This type of wound is more prevalent among older population. It has been estimated that up to 1-2% of the world population have this condition. The treatment of hard-to-heal wounds is expensive and long-term process, and, stresses healthcare systems of every country. Unfortunately, limited information is available about the situation with chronic wounds in Kazakhstan as the statistical data on such patients is not monitored and not registered in this country. Methods — The search was conducted by using available electronic sources, including Google Scholar, PubMed, Web of Sciences, Medline, Wiley Online Library, and Cochrane Library databases as well as hard copy versions of peer-reviewed publications in Russian, Kazakh, and English languages. Results — We have identified and analyzed current situation with wound care in the Republic of Kazakhstan. Research has demonstrated a variety of types of treatments utilized in the country, particularly the treatment of the diabetic foot.It also indicates the lack of statistics on wound care. Conclusions — The review highlights the mechanisms of wound healing process, methods for wound care, and encompasses the information available on wound healing in Republic of Kazakhstan. The article emphasizes the necessity of establishing the systemic monitoring of wound care and formation of electronic database. Apart from that, the importance of developing and manufacturing of domestic novel wound treatments have been also stressed out.

For a better understanding of wave - current interactions in the presence of a 3D bathymetry, a large scale experiment was carried out in the Ocean Basin FIRST, Toulon, France. The 3D bathymetry consisted of two symmetric underwater mounds on both sides in the mean wave direction. The water depth at the top the mounds was hm=1,5m, the slopes of the mounds were of about 1:3, the water depth was h=3 m elsewhere. For opposite current conditions (U of order 0.30m/s), a huge focusing of the wave up to twice its incident amplitude was observed in the central part of the basin for T=1.4s. Since deep water conditions are verified, the wave amplification is ascribed to the current field. The mean velocity fields at a water depth hC=0.25m was measured by the use of an electromagnetic current meter. The results have been published in Rey et al [4]. The elliptic form of the "mild slope" equation including a uniform current on the water column (Chen et al [1]) was then used for the calculations. The calculated wave amplification of factor 1.2 is significantly smaller than observed experimentally (factor 2). So, the purpose of this study is to understand the physical processes which explain this gap. As demonstrated by Kharif & Pelinovsky [2], geometrical focusing of waves is able to modify significantly the local wave amplitude. We consider this process here. Since vertical velocity profiles measured at some locations have shown significant

  6. On the incompatibilities of interaction scales and processes with focus on the work of adhesion.

    2016-08-01

    The mutual compatibility of Hamaker constants, solubility parameters or cohesive energy densities (CED) and surface/interface tensions are evaluated. It is shown that the partial contributions (dispersive, Lifshitz-van der Waals, dipolar induction, dipolar orientation, polar, acid, base and hydrogen bond) to Hamaker constants, solubility parameters or cohesive energy densities and surface/interface tensions are mutually inconsistent. The published reference data for a single set of liquids is moreover shown to be exceedingly scattered; making the parallel use of these scales challenging. Reference processes designed for bringing two and three phases into mutual contact are conflicting. The two-phase processes within Hamaker and exchange energy density (EED) frameworks agree, but the three-phase models differ. As a free-standing parameter the EED is however comparable. The two-phase adhesion process is shown to be incompatible with the other contact processes and the three-phase adhesion process is opposite to them. One reason for this controversy is the different averaging of interfacial properties. While interfacial Hamaker constants and solubility parameters or cohesive energy densities are geometric averages of corresponding intervening phase properties, this practice is replaced by the work of adhesion being geometrically averaged as works of cohesion. As a result, there exist three conflicting models for the adhesion process: the Dupré work of adhesion, the Girifalco-Good geometric averaged works of cohesion and Fowkes reduced interfacial or interphasial tension process. None of these agree with the commonly accepted standard Hamaker contact processes and they should be replaced with the compatible extended work of adhesion process originally suggested by Dupré. The models offered for the conversion of Hamaker constants and solubility parameters or cohesive energy densities to surface tensions involve conversion factors and equilibrium distances between

    2015-11-01

    Often in geophysical monitoring experiments time-lapse inversion models vary too smoothly with time, owing to the strong imprint of regularization. Several methods have been proposed for focusing the spatiotemporal changes of the model parameters. In this study, we present two generalizations of the minimum support norm, which favour compact time-lapse changes and can be adapted to the specific problem requirements. Inversion results from synthetic direct current resistivity models that mimic developing plumes show that the focusing scheme significantly improves size, shape and magnitude estimates of the time-lapse changes. Inversions of the synthetic data also illustrate that the focused inversion gives robust results and that the focusing settings are easily chosen. Inversions of full-decay time-domain induced polarization (IP) field data from a CO2 monitoring injection experiment show that the focusing scheme performs well for field data and inversions for all four Cole-Cole polarization parameters. Our tests show that the generalized minimum support norms react in an intuitive and predictable way to the norm settings, implying that they can be used in time-lapse experiments for obtaining reliable and robust results.

  8. The Effect of Driver Rise-Time on Pinch Current and its Impact on Plasma Focus Performance and Neutron Yield

    Science.gov (United States)

    Sears, Jason; Schmidt, Andrea; Link, Anthony; Welch, Dale

    2016-10-01

    Experiments have suggested that dense plasma focus (DPF) neutron yield increases with faster drivers [Decker NIMP 1986]. Using the particle-in-cell code LSP [Schmidt PRL 2012], we reproduce this trend in a kJ DPF [Ellsworth 2014], and demonstrate how driver rise time is coupled to neutron output. We implement a 2-D model of the plasma focus including self-consistent circuit-driven boundary conditions. Driver capacitance and voltage are varied to modify the current rise time, and anode length is adjusted so that run-in coincides with the peak current. We observe during run down that magnetohydrodynamic (MHD) instabilities of the sheath shed blobs of plasma that remain in the inter-electrode gap during run in. This trailing plasma later acts as a low-inductance restrike path that shunts current from the pinch during maximum compression. While the MHD growth rate increases slightly with driver speed, the shorter anode of the fast driver allows fewer e-foldings and hence reduces the trailing mass between electrodes. As a result, the fast driver postpones parasitic restrikes and maintains peak current through the pinch during maximum compression. The fast driver pinch therefore achieves best simultaneity between its ion beam and peak target density, which maximizes neutron production. Prepared by LLNL under Contract DE-AC52-07NA27344.

    2017-05-01

    We consider emotion- and instrumental-focused care work and marital stress during significant physical health events in midlife gay, lesbian, and heterosexual marriages. We employ the factorial method, an extension of the actor-partner interdependence model, to analyze survey data from 808 midlife gay, lesbian, and heterosexual spouses in 404 unions. The amount of emotion- and instrumental-focused care work provided during physical health events, and the associations between care work and marital stress, depends on the gender of the respondent, gender of the spouse, and whether spouses are in a same-sex or different-sex union. For example, in both same- and different-sex marriages, women report providing more emotion-focused care work during their own health event than do men, and respondents report more health-related marital stress when the patient is a woman. Investigating how midlife same-sex and different-sex spouses care for each other during a spouse's health event expands understandings of gendered aging experiences within marriage. Findings can elucidate health policies and clinical strategies that best support the health of men and women in same- and different-sex marriages.

  11. RETURN ON CURRENT ASSETS, WORKING CAPITAL AND REQUIRED RATE OF RETURN ON EQUITY

    Monika Bolek

    2014-08-01

    Full Text Available The problem of return on current assets and return on working capital related to the cost of equity invested in a company is analyzed in this paper. Risk – return and liquidity – profitability trade-offs influence the company’s equilibrium and management decisions. Liquidity is measured by the cash conversion cycle and it is related to the working capital strategy, measured by current ratio. Rate of return on current assets should be related to the rate of return on working capital that is linked to the cost of capital and the required rate of return. The results indicate that there is a positive relationship between the return on current assets and cash conversion cycle, a positive relationship between cost of equity and return on working capital meaning that the working capital, cash conversion cycle and current assets management are related to profitability, and cost of equity is determined by the required rate of return calculated based on the Capital Asset Pricing Model.

    2015-11-01

    A high current density (≈3 mA/cm(2)) hydrogen ion beam source operating in an extremely low-energy region (E(ib) ≈ 150-200 eV) has been realized by using a transition to a highly focused state, where the beam is extracted from the ion source chamber through three concave electrodes with nominal focal lengths of ≈350 mm. The transition occurs when the beam energy exceeds a threshold value between 145 and 170 eV. Low-level hysteresis is observed in the transition when E(ib) is being reduced. The radial profiles of the ion beam current density and the low temperature ion current density can be obtained separately using a Faraday cup with a grid in front. The measured profiles confirm that more than a half of the extracted beam ions reaches the target plate with a good focusing profile with a full width at half maximum of ≈3 cm. Estimation of the particle balances in beam ions, the slow ions, and the electrons indicates the possibility that the secondary electron emission from the target plate and electron impact ionization of hydrogen may play roles as particle sources in this extremely low-energy beam after the compensation of beam ion space charge.

    2016-04-01

    The aim of this study was to explore the work experience of perioperative nurses involved in robotic surgery. A qualitative descriptive study was conducted. Participants were 15 nurses who had been on a robotic surgery team at one of five major university hospitals in Seoul, South Korea. Participants were one male and 14 female nurses (mean age, 31.33 [SD, 4.19] years; range, 25-41 years). Their experience as robotic surgery nurses ranged from 8 months to 6 years. Nurses' experiences with robotic surgery were categorized within four main themes: (1) constant checking on patients' safety and the robot's functions; (2) unexpected robotic machine errors or malfunctions; (3) feelings of burden in a robotic surgical team; and (4) need and desire for more information and education. This study showed that there are common concerns about patient safety and the possibility of emergencies related to robot system failure among nurses. Offering more support for nurses involved in robotic surgery should be a priority to empower them to play an extended role in robotic surgery.

    The aim of this study was to explore factors that ameliorate work ability by focusing on workers' capacity to deal with stress.The subjects were 1,330 workers from the Japanese information technology (IT) sector. Each subject completed questionnaires in 2011 and 2012 that consisted of the work ability index (WAI), the three-item sense of coherence (SOC), and the Mental Health Improvement and Reinforcement Research of Recognition (MIRROR). The results of the WAI were also obtained in 2013. The median SOC score in 2011 was used to divide the subjects into two groups, the Low SOC group and the High SOC group, then we verified the factors that contributed to improved work ability in both of these groups over a two-year period. Results indicate that an improvement in work ability in the Low SOC group could be predicted by giving workers opportunities for education or training, by making efforts to reduce the stress of commuting, by clarifying their assignments, and by establishing support systems when troubles occur. For the High SOC group, such improvements could be predicted by giving workers job control, by giving education or training for the promotion of their abilities, and by establishing a system for assuming responsibility. In conclusion, improvements in the work environment can increase the work ability of Japanese IT workers in conformity with their capacity to deal with stress.

  17. Role of Working Memory Storage and Attention Focus Switching in Children’s Comprehension of Spoken Object Relative Sentences

    2014-01-01

    Full Text Available The present study evaluated a two-mechanism memory model of the online auditory comprehension of object relative (OR sentences in 7–11-year-old typically developing children. Mechanisms of interest included working memory storage (WMS and attention focus switching. We predicted that both mechanisms would be important for comprehension. Forty-four children completed a listening span task indexing WMS, an auditory attention focus switching task, and an agent selection task indexing spoken sentence comprehension. Regression analyses indicated that WMS and attention focus switching accuracy each accounted for significant and unique variance in the children’s OR comprehension after accounting for age. Results were interpreted to suggest that WMS is important for OR comprehension by supporting children’s ability to retain both noun phrase 1 and noun phrase 2 prior to their reactivating noun phrase 1 from memory in order to integrate it into a developing structure. Attention focus switching was interpreted to be critical in supporting children’s noun phrase 1 reactivation, as they needed to switch their focus of attention momentarily away from ongoing language processing to memory retrieval.

    2015-09-01

    Despite doubts voiced on their efficacy, a series of studies has been carried out on the capacity of training programmes to improve academic and reasoning skills by focusing on underlying cognitive abilities and working memory in particular. No systematic efforts have been made, however, to test training programmes that involve both general and specific underlying abilities. If effective, these programmes could help to increase students' motivation and competence. This study examined the feasibility of improving problem-solving skills in school children by means of a training programme that addresses general and specific abilities involved in problem solving, focusing on metacognition and working memory. The project involved a sample of 135 primary school children attending eight classes in the third, fourth, and fifth grades (age range 8-10 years). The classes were assigned to two groups, one attending the training programme in the first 3 months of the study (Training Group 1) and the other serving as a waiting-list control group (Training Group 2). In the second phase of the study, the role of the two groups was reversed, with Training Group 2 attending the training instead of Training Group 1. The training programme led to improvements in both metacognitive and working memory tasks, with positive-related effects on the ability to solve problems. The gains seen in Training Group 1 were also maintained at the second post-test (after 3 months). Specific activities focusing on metacognition and working memory may contribute to modifying arithmetical problem-solving performance in primary school children. © 2015 The British Psychological Society.

    Introduction: The current study examined if adaptive working memory training (Cogmed QM) has the potential to improve inhibitory control, working memory capacity, and perceptions of memory functioning in a group of patients currently on sick leave due to symptoms of pain, insomnia, fatigue, depression and anxiety. Participants who were referred to a vocational rehabilitation center volunteered to take part in the study. Methods: Participants were randomly assigned to either a training condition (N = 25) or a control condition (N = 29). Participants in the training condition received working memory training in addition to the clinical intervention offered as part of the rehabilitation program, while participants in the control condition received treatment as usual i.e., the rehabilitation program only. Inhibitory control was measured by The Stop Signal Task, working memory was assessed by the Spatial Working Memory Test, while perceptions of memory functioning were assessed by The Everyday Memory Questionnaire-Revised. Results: Participants in the training group showed a significant improvement on the post-tests of inhibitory control when compared with the comparison group (p = 0.025). The groups did not differ on the post-tests of working memory. Both groups reported less memory problems at post-testing, but there was no sizeable difference between the two groups. Conclusions: Results indicate that working memory training does not improve general working memory capacity per se. Nor does it seem to give any added effects in terms of targeting and improving self-perceived memory functioning. Results do, however, provide evidence to suggest that inhibitory control is accessible and susceptible to modification by adaptive working memory training. PMID:28111555

    The effect of three different anode shapes, flat, tapered and hemispherical, on the x-ray emission characteristics of a neon filled UNU-ICTP plasma focus device is investigated. The current sheath dynamics, in the radial collapse phase, has been simultaneously interrogated using the laser shadowgraphy method to understand the variation in x-ray emission characteristics for anodes of different shapes used in the experiments. The maximum neon soft x-ray (SXR) yield for the flat anode is about 7.5 {+-} 0.4 J at 4 mbar, whereas for hemispherical and tapered anodes the neon SXR is almost halved with the optimum pressure shifting to a lower value of 3 mbar. The laser shadowgraphic images confirm that the reduction in the overall neon SXR yield is due to the reduced focused plasma column length for these anodes. The relative HXR yield was the highest for the hemispherical anode followed by the tapered and the flat anodes in that order. The shadowgraphic images and the voltage probe signals confirmed that for the hemispherical anode the multiple-pinch phenomenon was most commonly observed, which could be responsible for multiple HXR bursts for this anode with maximum HXR yields.

    To investigate the biomedical scientist's perception of the prevailing publication culture. Qualitative focus group interview study. Four university medical centres in the Netherlands. Three randomly selected groups of biomedical scientists (PhD, postdoctoral staff members and full professors). Main themes for discussion were selected by participants. Frequently perceived detrimental effects of contemporary publication culture were the strong focus on citation measures (like the Journal Impact Factor and the H-index), gift and ghost authorships and the order of authors, the peer review process, competition, the funding system and publication bias. These themes were generally associated with detrimental and undesirable effects on publication practices and on the validity of reported results. Furthermore, senior scientists tended to display a more cynical perception of the publication culture than their junior colleagues. However, even among the PhD students and the postdoctoral fellows, the sentiment was quite negative. Positive perceptions of specific features of contemporary scientific and publication culture were rare. Our findings suggest that the current publication culture leads to negative sentiments, counterproductive stress levels and, most importantly, to questionable research practices among junior and senior biomedical scientists.

Video recordings of the focus group sessions were transcribed and a thematic analysis was performed.Results: Participants reported the need for assessment and diagnostic tools that are accessible and efficient, and that are capable of accommodating the rapid growth in the aging population. The prevalence of more complex ailments experienced by older adults has had repercussions in the quality of care that the clients receive, and has contributed to lengthy wait times and resource shortages. Health-care professionals stated that they are hampered by the disjointed structure of the health-care system and that they would benefit from a more efficient allocation of responsibilities made possible through tools that did not require extensive training or certification. Eyetracking-based cognitive assessments were thought to strongly complement this system, yet it was thought that difficulty would be faced in gaining the support and increased uptake by health-care professionals due to the nonintuitive relationship between eyetracking and cognition.Conclusion: The findings suggest that health-care professionals are receptive to the use of eyetracking technology to assess for cognitive health as it would conserve resources by allowing frontline staff to administer assessments with minimal training

    Little research has been undertaken into occupational health and safety in the Prosthetics and Orthotics profession. To identify physical, psychosocial and environmental workplace experiences of Prosthetists and Orthotists in organisational settings. Qualitative methodology, cross-sectional design, using thematically analysed data collected from focus groups. Focus groups explored workplace and work experiences across varied Prosthetic and Orthotic settings. Data were thematically analysed to identify physical, psychosocial and environmental workplace experiences. Three major themes, Demands of Work Practice, Impacts on the Individual and Job Design, were identified as problematic. A latent theme Perceptions of Others of P&O highlighted a lack of understanding of the Prosthetics and Orthotics job role outside the profession. This first study of occupational health and safety in the Prosthetics and Orthotics profession identifies a number of important physical and psychosocial issues, including characteristics that have been previously identified as risk factors for work-related musculoskeletal disorders. Findings from the study indicate that some Australian organisations lack understanding of the Prosthetics and Orthotics job role, which results in inappropriate expectations of Prosthetics and Orthotics professionals. Preventing injuries and retaining experienced Prosthetists and Orthotists in the workplace is vital for the profession, and as a result, issues raised in this study require further exploration and then development of appropriate management strategies. This is the first study characterising the experiences of work and risk of injuries in Prosthetists and Orthotists. Preventing injuries and retaining experienced Prosthetists and Orthotists in the workplace is vital for the international profession.

    Full Text Available We deeply appreciate your publishing of our work - “Chronic metabolic acidosis destroys pancreas” in JOP (2014 [1]. We feel that our work can give the food for thought to many young researchers and health practitioners. A short review of our work may generate various questions and ideas for further investigations. In our work, we have focused on negative affects of the chronic metabolic acidosis on pancreatic function including: • Premature activation of the proteases within the pancreas • Diminishing the antimicrobial activity of the pancreatic juice • Suppressing of the flushing out zymogens from the pancreas • Precipitation of the aggressive bile acids • Calcification Authors believe that further research may provide more details of how the acidification destroys the pancreas and causes chronic pancreatitis. We would like to share some of our thoughts on this subject as follows: Descriptions of symptoms of chronic pancreatitis such as pain, malabsorption syndrome, steatorrhea, and weight loss are found in almost all medical books, textbooks, and articles. The medical literature refers to these conditions as “pancreatic insufficiency”. It is known that these symptoms occur when only 10 % of the exocrine pancreatic function is left intact. This is not an “insufficiency.” It is a pancreatic “failure” when the therapeutic opportunities are very limited.

    Occupational sitting can be the largest contributor to overall daily sitting time in white-collar workers. With adverse health effects in adults, intervention strategies to influence sedentary time on a working day are needed. Therefore, the present aim was to examine employees' and executives' reflections on occupational sitting and to examine the potential acceptability and feasibility of intervention strategies to reduce and interrupt sedentary time on a working day. Seven focus groups (four among employees, n = 34; three among executives, n = 21) were conducted in a convenience sample of three different companies in Flanders (Belgium), using a semi-structured questioning route in five themes [personal sitting patterns; intervention strategies during working hours, (lunch) breaks, commuting; and intervention approach]. The audiotaped interviews were verbatim transcribed, followed by a qualitative inductive content analysis in NVivo 10. The majority of participants recognized they spend their working day mostly sitting and associated this mainly with musculoskeletal health problems. Participants suggested a variety of possible strategies, primarily for working hours (standing during phone calls/meetings, PC reminders, increasing bathroom use by drinking more water, active sitting furniture, standing desks, rearranging the office) and (lunch) breaks (physical activity, movement breaks, standing tables). However, several barriers were reported, including productivity concerns, impracticality, awkwardness of standing, and the habitual nature of sitting. Facilitating factors were raising awareness, providing alternatives for simply standing, making some strategies obligatory and workers taking some personal responsibility. There are some strategies targeting sedentary time on a working day that are perceived to be realistic and useful. However several barriers emerged, which future trials and practical initiatives should take into account.

However, the comparative effects between these five approaches have not been well studied; thus, we are not able to clearly understand the superiority of any of these interventions. With the exception of patient relapse, the longer-term (eg, >2 years effects of these approaches on most psychosocial outcomes are not well-established among these patients. Despite the fact that patients' perspectives on treatment and care have been increasingly concerned, not many studies have evaluated the effect of interventions on this perspective, and where they did, the findings were inconclusive. To conclude, current approaches to psychosocial interventions for schizophrenia have their strengths and weaknesses, particularly indicating limited evidence on long-term effects. To improve the longer-term outcomes of people with schizophrenia, future treatment strategies should focus on risk identification, early intervention, person-focused therapy, partnership with family caregivers, and the integration of evidence-based psychosocial interventions into existing services.

    Objectives This paper reviews the current state of the published peer-reviewed literature related to return-to-work (RTW) interventions that incorporate work-related problem-solving skills for workers with sickness absences related to mental disorders. It addresses the question: What is the evidence for the effectiveness of these RTW interventions? Design Using a multiphase screening process, this systematic literature review was based on publically available peer-reviewed studies. Five electronic databases were searched: (1) Medline Current, (2) Medline In-process, (3) PsycINFO, (4) Econlit and (5) Web of Science. Setting The focus was on RTW interventions for workers with medically certified sickness absences related to mental disorders. Participants Workers with medically certified sickness absences related to mental disorders. Interventions RTW intervention included work-focused problem-solving skills. Primary and secondary outcome measures RTW rates and length of sickness absences. Results There were 4709 unique citations identified. Of these, eight articles representing a total of six studies were included in the review. In terms of bias avoidance, two of the six studies were rated as excellent, two as good and two as weak. Five studies were from the Netherlands; one was from Norway. There was variability among the studies with regard to RTW findings. Two of three studies reported significant differences in RTW rates between the intervention and control groups. One of six studies observed a significant difference in sickness absence duration between intervention and control groups. Conclusions There is limited evidence that combinations of interventions that include work-related problem-solving skills are effective in RTW outcomes. The evidence could be strengthened if future studies included more detailed examinations of intervention adherence and changes in problem-solving skills. Future studies should also examine the long-term effects of problem

    Direct measurement of axial magnetic field in the PF-1000 dense plasma focus (DPF), and its reported correlation with neutron emission, call for a fresh look at previous reports of existence of axial magnetic field component in the DPF from other laboratories, and associated data suggesting toroidal directionality of fast ions participating in fusion reactions, with a view to understand the underlying physics. In this context, recent work dealing with application of the hyperbolic conservation law formalism to the DPF is extended in this paper to a curvilinear coordinate system, which reflects the shape of the DPF current sheath. Locally-unidirectional shock propagation in this coordinate system enables construction of a system of 7 one-dimensional hyperbolic conservation law equations with geometric source terms, taking into account all the components of magnetic field and flow velocity. Rankine-Hugoniot jump conditions for this system lead to expressions for the axial magnetic field and three components of ...

    Full Text Available Cognitive deficits are reported in diabetes mellitus type 2 (DM2. Previous research has shown that music-based intervention can not only reduce hyperglycemia but also target cognitive functions as well as stress. The aim of this exploratory study was to understand the effect of active participation in music therapy (MT on the cognitive deficits of DM2 patients. MT of twenty sessions was carried out with three participants with DM2. Serum cortisol, perceived stress, Color Trail Test (1 and 2, and verbal n-back (1 and 2 tests were used to measure the outcomes. Feedback was taken for the subjective ratings and satisfaction of the participants. Stress and cortisol reduced and focused attention and working memory improved in varying degrees. Subjectively, participants reported having benefitted from the intervention. This is the first attempt to investigate the effect of music-based intervention on cognitive function in DM2 patients using case study approach.

    Full Text Available Patrick P Kneeland, Margaret C FangThe University of California, San Francisco Division of Hospital Medicine, San Francisco, CA, USAAbstract: Warfarin therapy reduces morbidity and mortality related to thromboembolism. Yet adherence to long-term warfarin therapy remains challenging due to the risks of anticoagulantassociated complications and the burden of monitoring. The aim of this paper is to review determinants of adherence and persistence on long-term anticoagulant therapy for atrial fibrillation and venous thromboembolism. We evaluate what the current literature reveals about the impact of warfarin on quality of life, examine warfarin trial data for patterns of adherence, and summarize known risk factors for warfarin discontinuation. Studies suggest only modest adverse effects of warfarin on quality of life, but highlight the variability of individual lifestyle experiences of patients on warfarin. Interestingly, clinical trials comparing anticoagulant adherence to alternatives (such as aspirin show that discontinuation rates on warfarin are not consistently higher than in control arms. Observational studies link a number of risk factors to warfarin non-adherence including younger age, male sex, lower stroke risk, poor cognitive function, poverty, and higher educational attainment. In addition to differentiating the relative impact of warfarin-associated complications (such as bleeding versus the lifestyle burdens of warfarin monitoring on adherence, future investigation should focus on optimizing patient education and enhancing models of physician–patient shared-decision making around anticoagulation.Keywords: anticoagulation, warfarin, adherence, persistence, thromboembolism

    Metacognition and working memory (WM) have been found associated with success in reading comprehension, but no studies have examined their combined effect on the training of reading comprehension. Another open question concerns the role of listening comprehension: In particular, it is not clear whether training to improve reading comprehension must necessarily be based on processing written material or whether, as suggested in a recent study by Clarke et al. (2010, Psychol. Sci., 21, 1106), a programme based on verbal language could also be effective. The study examined the feasibility of improving text comprehension in school children by comparing the efficacy of two training programmes, both involving metacognition and WM, but one based on listening comprehension, the other on reading comprehension. The study involved a sample of 159 pupils attending eight classes in the fourth and fifth grades (age range 9-11 years). The listening and reading programmes focused on the same abilities/processes strictly related to text comprehension, and particularly metacognitive knowledge and control, WM (per se and in terms of integrating information in a text). The training programmes were implemented by school teachers as part of the class's normal school activities, under the supervision of experts. Their efficacy was compared with the results obtained in an active control group that completed standard text comprehension activities. Our results showed that both the training programmes focusing on specific text comprehension skills were effective in improving the children's achievement, but training in reading comprehension generated greater gains than the listening comprehension programme. Our study suggests that activities focusing specifically on metacognition and WM could foster text comprehension, but the potential benefit is influenced by the training modality, that is, the Reading group obtained greater and longer-lasting improvements than the Active control or

    The concept of attention has a prominent place in cognitive psychology. Attention can be directed not only to perceptual information, but also to information in working memory (WM). Evidence for an internal focus of attention has come from the retro-cue effect: Performance in tests of visual WM is improved when attention is guided to the test-relevant contents of WM ahead of testing them. The retro-cue paradigm has served as a test bed to empirically investigate the functions and limits of the focus of attention in WM. In this article, we review the growing body of (behavioral) studies on the retro-cue effect. We evaluate the degrees of experimental support for six hypotheses about what causes the retro-cue effect: (1) Attention protects representations from decay, (2) attention prioritizes the selected WM contents for comparison with a probe display, (3) attended representations are strengthened in WM, (4) not-attended representations are removed from WM, (5) a retro-cue to the retrieval target provides a head start for its retrieval before decision making, and (6) attention protects the selected representation from perceptual interference. The extant evidence provides support for the last four of these hypotheses.

    The potential health effects of exposure to nanomaterials (NMs) is currently heavily studied. Among the most often reported impact is DNA damage, also termed genotoxicity. While several reviews relate the DNA damage induced by NMs and the techniques that can be used to prove such effects, the question of impact of NMs on DNA repair processes has never been specifically reviewed. The present review article proposes to fill this gap of knowledge by critically describing the DNA repair processes that could be affected by nanoparticle (NP) exposure, then by reporting the current state of the art on effects of NPs on DNA repair, at the level of protein function, gene induction and post-transcriptional modifications, and taking into account the advantages and limitations of the different experimental approaches. Since little is known about this impact, working hypothesis for the future are then proposed.

    Studies attempting to increase working memory (WM) capacity show promise in enhancing related cognitive functions but have also raised criticism in the broader scientific community given the inconsistent findings produced by these studies. Transcranial direct current stimulation (tDCS) has been shown to enhance WM performance in a single session [Fregni, F., Boggio, P., Nitsche, M., Bermpohl, F., Anatal, A., Feredoes, E., et al. Anodal transcranial direct current stimulation of prefrontal cortex enhances working memory. Experimental Brain Research, 166, 23-30, 2005]; however, the extent to which tDCS might enhance learning on a WM training regime and the extent to which learning gains might transfer outside the training task remains largely unknown. To this end, participants engaged in an adaptive WM training task [previously utilized in Richmond, L., Morrison, A., Chein, J., & Olson, I. Working memory training and transfer in older adults. Psychology & Aging, 26, 813-822, 2011; Chein, J., & Morrison, A. Expanding the mind's workspace: Training and transfer effects with a complex working memory span task. Psychonomic Bulletin & Review, 17, 193-199, 2010] for 10 sessions over 2 weeks, concurrent with either active or sham stimulation of dorsolateral pFC. Before and after training, a battery of tests tapping domains known to relate to WM abilities was administered. Results show that tDCS enhanced learning on the verbal portion of the training task by 3.65 items. Furthermore, tDCS was shown to enhance near transfer to other untrained WM tasks in comparison with a no-contact control group. These results lend support to the idea that tDCS might bolster training and transfer gains in populations with compromised WM abilities.

    Full Text Available Studies on the passage from educational institutions to work and adult life have gained momentum in the framework of the employment crisis. Since the 1980s, changes in the situations that affect the life trajectories of contemporary youth have been a topic of discussion. This article addresses such issues by analyzing the educational and work careers of a group of young urban Argentines. The study focuses on a particular moment of their trajectories: that of the transition from high school graduation to higher education and/or work. In this way we attempt to reach a substantive discussion on those discretionary and/or determining factors that can be identified in the configuration of these transitions as well as on the points of tension that were encountered. The research is based on a reconstruction of the experiences of a group of youth (Cohort-2003 from different public and private high schools in townships in the cities of Buenos Aires and La Plata, Argentina, and involves the description given by these young people and their perception of the various scenarios that comprise their traveled paths.

    Work-related stress is a global problem with negative implications for individuals and society. The purpose of the current study was to evaluate a stress management intervention for patients on sick leave due to work-related stress complaints using a three-armed randomized controlled design. Participants were patients referred from three municipalities to the regional Department of Occupational Medicine. Inclusion criteria were: 1) sick leave due to work-related stress complaints, 2) a diagnosis of adjustment disorder or reactions to severe stress (ICD 10 code: F43,2 - F 43,9 not PTSD) or mild depressive episode (F 32.0). Through a double randomization procedure patients (n = 163) were randomized to either an intervention group (n = 58), a 'control group A' receiving a clinical examination (n = 56), or 'control group B' (n = 49) receiving no offers at the department. The intervention comprised six sessions of individual cognitive behavioral therapy and the offer of a small workplace intervention. Questionnaire data were analyzed with multivariate repeated measurements analysis. Primary outcomes assessed were perceived stress and general mental health. Secondary outcomes were sleep quality and cognitive failures. Follow-up was at four and 10 months after baseline. Complaints were significantly reduced in all groups over time. No group effects were observed between the intervention group and control group A that was clinically assessed. Significant group effects were found for perceived stress and memory when comparing the intervention group to group B, but most likely not due to an intervention effect. Psychological complaints improved substantially over time in all groups, but there was no significant treatment effect on any outcomes when the intervention group was compared to control group A that received a clinical assessment.

Users are current students and recommendations can be built upon paths (both formal and informal, relationships, behaviours, friends, followers, actions, grades, tutor interaction, etc. A recommender system must somehow retrieve, categorize and work with all these details. There are several ways to do so: from raw and inelegant database access to more curated web APIs or even via HTML scrapping. New server-centric user-action logging and monitoring standard technologies have been presented in past years by several groups, organizations and standard bodies. The Experience API (xAPI, detailed in this article, is one of these. In the first part of this paper we analyse current learner-monitoring techniques as an initialization phase for eLearning recommender systems. We next review standardization efforts in this area; finally, we focus on xAPI and the potential interaction with the LIME model, which will be also summarized below.

    The United States Department of Energy (DOE) executed a contract with Memphis Light, Gas and Water Division (MLGW) which requires MLGW to perform process analysis, design, procurement, construction, testing, operation, and evaluation of a plant which will demonstrate the feasibility of converting high sulfur bituminous coal to industrial fuel gas with a heating value of 300 +- 30 Btu per standard cubic foot (SCF). The demonstration plant is based on the U-Gas process, and its product gas is to be used in commercial applications in Memphis, Tenn. The contract specifies that the work is to be conducted in three phases. The Phases are: Phase I - Program Development and Conceptual Design; Phase II - Demonstration Plant Final Design, Procurement and Construction; and Phase III - Demonstration Plant Operation. Under Task III of Phase I, a Cost Estimate for the Demonstration Plant was completed as well as estimates for other Phase II and III work. The output of this Estimate is presented in this volume. This Current Working Estimate for Phases II and III is based on the Process and Mechanical Designs presented in the Task II report (second issue) and the 12 volumes of the Task III report. In addition, the capital cost estimate summarized in the appendix has been used in the Economic Analysis (Task III) Report.

    Full Text Available Introduction. The nature of the interaction of high-working surfaces of the electrical contact uniquely affects their performance. By the failure of the contacts in the main drive processes resulting from complex destructive factors affecting their performance. However, not all processes are studied in detail and give in modeling. The purpose of the paper is to show the possibility of using the method of holographic interferometry to estimate the plastic deformation in the zone of contact interaction. One of the significant factors affecting the work of the contact pair is the compressive force of the contact surfaces. Compression discontinuous contact is directly connected with the processes of elastic and plastic deformation of the contact material, which is particularly evident in the contact details of the powder or composite materials. The paper focuses on the plastic deformation of the surface layers of discontinuous contact in circuit, it is believed that it is directly related to the mechanism of conductivity of contacts. As shown, a significant effect on the deformation of the contact surfaces and renders the working environment, in particular transformer oil. Methodology. Assessing the impact of compression forces on the deformation of the contact surface was conducted experimentally using the method of holographic interferometry. Results. Experimental studies, which indicated that the compact and powder materials plastic deformation in and around the area microcontacts simplistically stated that requires experimental verification. A method for evaluating the state of stress, which affects the formation and destruction of the local contact spots. Practical value. Using the experimental method of determining the movement of the contact region allows you to optimize discontinuous contacts from composite and powder materials.

    The role of the posterior parietal cortex in working memory (WM) is poorly understood. We previously found that patients with parietal lobe damage exhibited a selective WM impairment on recognition but not recall tasks. We hypothesized that this dissociation reflected strategic differences in the utilization of attention. One concern was that these findings, and our subsequent interpretation, would not generalize to normal populations because of the patients' older age, progressive disease processes, and/or possible brain reorganization following injury. To test whether our findings extended to a normal population we applied transcranial direct current stimulation (tDCS) to right inferior parietal cortex. tDCS is a technique by which low electric current applied to the scalp modulates the resting potentials of underlying neural populations and can be used to test structure-function relationships. Eleven normal young adults received cathodal, anodal, or sham stimulation over right inferior posterior parietal cortex and then performed separate blocks of an object WM task probed by recall or recognition. The results showed that cathodal stimulation selectively impaired WM on recognition trials. These data replicate and extend our previous findings of preserved WM recall and impaired WM recognition in patients with parietal lobe lesions. Copyright 2010 Elsevier Ireland Ltd.

    Full Text Available This study involved the examination of 1,006 chest x-ray films of workers from the industries devoted to shipyard welding, stone grinding, and refractory crushing in southern Okayama prefecture. Of the reviewed films, analysis was focused on subjects with a profusion rate of 0/1 as well as pneumoconiotic subjects (exhibiting profusion rates of 1/0 or greater in order to discover cases in the beginning stages. One-hundred-and-seventy-four films illustrated a profusion rate of 0/1 or greater, and the proportion of this profusion rate was revealed to be highest in shipyard welders. Even some workers under 40 years of age were found to have already developed pneumoconiosis. Of these 1,006 subjects, 30 volunteers permitted us to measure their personal dust exposure concentrations. The measured concentration of the shipyard welders' dust exposure (respirable dust; 3.3 86.3 mg/m3, total dust; 7.5-117.0 mg/m3 was higher than those of the other 2 industries. Statistical differences among the industries were observed in the respirable dust concentrations. A statistically significant positive correlation was demonstrated between the working duration in dusty environments and the rate of profusion. The present findings suggest the need for taking adequate measures in Okayama in order to prevent workers from developing, or to help retard the progression of, pneumoconiosis.

    Although working memory (WM) training programs consistently result in improvement on the trained task, benefit is typically short-lived and extends only to tasks very similar to the trained task (i.e., near transfer). It is possible that pairing repeated performance of a WM task with brain stimulation encourages plasticity in brain networks involved in WM task performance, thereby improving the training benefit. In the current study, transcranial direct current stimulation (tDCS) was paired with performance of a WM task (n-back). In Experiment 1, participants performed a spatial location-monitoring n-back during stimulation, while Experiment 2 used a verbal identity-monitoring n-back. In each experiment, participants received either active (2.0mA) or sham (0.1mA) stimulation with the anode placed over either the right or the left dorsolateral prefrontal cortex (DLPFC) and the cathode placed extracephalically. In Experiment 1, only participants receiving active stimulation with the anode placed over the right DLPFC showed marginal improvement on the trained spatial n-back, which did not extend to a near transfer (verbal n-back) or far transfer task (a matrix-reasoning task designed to measure fluid intelligence). In Experiment 2, both left and right anode placements led to improvement, and right DLPFC stimulation resulted in numerical (though not sham-adjusted) improvement on the near transfer (spatial n-back) and far transfer (fluid intelligence) task. Results suggest that WM training paired with brain stimulation may result in cognitive enhancement that transfers to performance on other tasks, depending on the combination of training task and tDCS parameters used.

    Actually all ex-core detector signal data processing and extracting the final conclusion about the single control bank was performed by the 3rd generation of Digital Reactivity Computer System (DRCS). From 2006 to 2016, about 250 control bank worths were measured and the difference between measured and calculated worth of individual bank were several % and total rod worth differences of each cycle were less than 3%. However there were a few odd cases showing the individual difference greater than 15% which is the criteria. And some OPR1000 nuclear power plants built recently use fission chambers instead of traditional uncompensated ion chambers. To consider those conditions, any modification of the DCRM method and DRCS were requested. In this paper, short description about DCRM method, current status of DCRM modification and future works are discussed. About 10 cases among about 250 control bank worth measurement with original DCRM method with UIC signals result in very heavy fluctuation on reactivity curve and the difference approaches 15%, the individual limit. The electrometer signals processing method were the main cause. To overcome this problem, a modified reactivity computer system using own current treatment logic was designed. It shows the reactivity fluctuation can be reduced dramatically in case of UIC signal. Recently the modified DRCS coupled INVESE code applied Westinghouse 2 Loop plant and gave very good results except a control bank whose measured rod worth was shown of 18% difference from the estimated value. The results were same for three repeat tests. All possible causes are examined from computer codes to detail data acquisition system.

    This report describes the work that Environmental Energy Technologies Division of Lawrence Berkeley National Laboratory has been doing most recently. One of our proudest accomplishments is the publication of Scenarios of U.S. Carbon Reductions, an analysis of the potential of energy technologies to reduce carbon emissions in the U.S. This analysis played a key role in shaping the U.S. position on climate change in the Kyoto Protocol negotiations. Our participation in the fundamental characterization of the climate change issue by the IPCC is described. We are also especially proud of our study of ''leaking electricity,'' which is stimulating an international campaign for a one-watt ceiling for standby electricity losses from appliances. This ceiling has the potential to save two-thirds of the 5% of U.S. residential electricity currently expended on standby losses. The 54 vignettes contained in the following pages summarize results of research. activities ranging in scale from calculating the efficacy of individual lamp ballasts to estimating the cost-effectiveness of the national ENERGY STAR{reg_sign} labeling program, and ranging in location from a scoping study of energy-efficiency market transformation in California to development of an energy-efficiency project in the auto parts industry in Shandong Province, China. These are the intellectual endeavors of a talented team of researchers dedicated to public service.

    Latina women are a growing percentage of the working population, and very little is known about their health needs and interests. The purpose of this article is to share qualitative research results gathered from Latina women with a particular focus on exploring stress and health. This project was a substudy of Health Works in the Community, a 5-year CDC-funded multiple risk-factor reduction trial using participatory action research approaches to address smoking, healthy eating, stress, and physical activity among blue-collar women from 12 manufacturing work sites in rural, eastern North Carolina. Five focus groups were conducted with trained, bilingual facilitators using a vignette-based moderator guide that appeared particularly effective with this population. Results from the focus groups are used to make recommendations for future research with Latinas and for developing effective work-site-based interventions to address issues of stress and health within this population.

    The challenges as we strive towards universal health coverage are many, but the need for an improved health workforce is chief among them. Unfortunately the global deficit in skilled professionals continues to increase. Nevertheless, there are potential solutions, and success stories are well documented when the approach is on system building and sustainability. As we approach 2015 and the Millennium Development Goals, we must shift our focus to a more distant time point in order to achieve the dramatic gains in global health that are possible. However, we must understand that there can be no health without a workforce.

    The paper concerns fast protons and neutrons from D-D fusion reactions in a Plasma-Focus-1000U facility. Measurements were performed with nuclear-track detectors arranged in “sandwiches” of an Al-foil and two PM-355 detectors separated by a polyethylene-plate. The Al-foil eliminated all primary deuterons, but was penetrable for fast fusion protons. The foil and first PM-355 detector were penetrable for fast neutrons, which were converted into recoil-protons in the polyethylene and recorded in the second PM-355 detector. The “sandwiches” were irradiated by discharges of comparable neutron-yields. Analyses of etched tracks and computer simulations of the fusion-products behavior in the detectors were performed.

    Cardiovascular diseases (CVD) are among the leading causes of morbidity and mortality in Brazil. Cardiac rehabilitation (CR) is a program composed of structured exercise training, comprehensive education and counseling to positively impact functional, psychological, social, and quality of life aspects in these patients. However, the delivery of formal CR programs is limited to major metropolitan centers in Brazil and does not exist in much of the national territory, specifically in the North and Northeast regions. Barriers to the inclusion of qualified patients are lack of referral by the health professionals, as well as transportation difficulties, low income, lack of insurance coverage, and low educational level. Government efforts to implement CR programs on a broader scale, to reach a larger portion of the CVD population, are imperative. Additional research must be focused on the assessment of CR referral and adherence patterns as well as the effectiveness of different CR delivery models.

    In this study, we surveyed the current status, satisfaction and demand of radiologic technologist continuing education for 93 radiologic technologists who participated in the continuing education. To understand the current status and general evaluation and to find out the improvement direction, survey was conducted on 3 categories: participation, satisfaction and demand of continuing education. In addition, we analyzed the continuing education implementation status and the management system by collecting related regulations. As a result, the education completion rates of radiologic technologists from 2010 to 2012 were respectively 42.6%, 43.4% and 34.2%; the rates were similar to other medical technician’s average education completion rates. According to the survey, in case of participation, the most frequent answer was ‘more than five times less than 10 times per year’ with 48.4% and in satisfaction section, the most common answer was ‘Average(3)’ with 34.4%. In demand of continuing education section, 32.8% of the respondents chose ‘Clinical skill training in major field’. In the results of this research, continuing education needs to be managed in the direction of helping radiologists improve their personal ability and self development. Furthermore, to meet the demand of radiologists, the quality of continuing education should be improved to satisfy the educatee.

    The paper presents results of experimental studies of dense and high-temperature plasmas, which were produced by pulsed high-current discharges within a modernised PF-1000U facility operated at different initial gas conditions, and supplied from a condenser bank which delivered energy of about 350 kJ. The investigated discharges were performed at the initial deuterium filling under pressure of 1.6-2.0 hPa, with or without an additional puffing of pure deuterium (1 cm3, under pressure 0.15 MPa, at instants 1.5-2 ms before the main discharge initiation). For a comparison discharges were also performed at the initial neon filling under pressure of 1.1-1.3 hPa, with or without the addition of deuterium puffing. The recorded discharge current waveforms, laser interferometric images, signals of hard x-rays and fusion neutrons, as well as time-integrated x-ray pinhole images and time-resolved x-ray signals were compared. From a ratio of the x-ray signals recorded behind beryllium filters of different thickness there were estimated values of a plasma electron temperature (T e) in a region at the electrode outlets. For pure deuterium discharges an averaged T e value amounted to 150-170 eV, while for neon discharges with the deuterium puffing it reached 330-880 eV (with accuracy of  ±20%).

    Background High intensity focused ultrasound (HIFU) is emerging as a valid minimally-invasive image-guided treatment of malignancies. We aimed to review to current state of the art of HIFU therapy applied to the digestive system and discuss some promising avenues of the technology. Methods Pertinent studies were identified through PubMed and Embase search engines using the following keywords, combined in different ways: HIFU, esophagus, stomach, liver, pancreas, gallbladder, colon, rectum, and cancer. Experimental proof of the concept of endoluminal HIFU mucosa/submucosa ablation using a custom-made transducer has been obtained in vivo in the porcine model. Results Forty-four studies reported on the clinical use of HIFU to treat liver lesions, while 19 series were found on HIFU treatment of pancreatic cancers and four studies included patients suffering from both liver and pancreatic cancers, reporting on a total of 1,682 and 823 cases for liver and pancreas, respectively. Only very limited comparative prospective studies have been reported. Conclusions Digestive system clinical applications of HIFU are limited to pancreatic and liver cancer. It is safe and well tolerated. The exact place in the hepatocellular carcinoma (HCC) management algorithm remains to be defined. HIFU seems to add clear survival advantages over trans arterial chemo embolization (TACE) alone and similar results when compared to radio frequency (RF). For pancreatic cancer, HIFU achieves consistent cancer-related pain relief. Further research is warranted to improve targeting accuracy and efficacy monitoring. Furthermore, additional work is required to transfer this technology on appealing treatments such as endoscopic HIFU-based therapies. PMID:27500145

    2015-01-01

    This review discusses our current understanding of how the expression and turnover of components of the cartilage extracellular matrix (ECM) have been investigated, both as molecular markers of arthritis and as indicators of disease progression. The cartilage ECM proteome is well studied; it contains proteoglycans (aggrecan, perlecan and inter-α-trypsin inhibitor), collagens and glycoproteins (cartilage oligomeric matrix protein, fibronectin and lubricin) that provide the structural and functional changes in arthritis. However, the changes that occur in the carbohydrate structures, including glycosaminoglycans, with disease are less well studied. Investigations of the cartilage ECM proteome have revealed many potential biomarkers of arthritis. However, a clinical diagnostic or multiplex assay is yet to be realized due to issues with specificity to the pathology of arthritis. The future search for clinical biomarkers of arthritis is likely to involve both protein and carbohydrate markers of the ECM through the application of glycoproteomics.

    Full Text Available Gregory MT Guilcher,1 Douglas A Stewart21University of Calgary, Section of Hematology/Oncology/Transplant, Alberta Children’s Hospital, Calgary, Canada; 2University of Calgary, Division of Medical Oncology, Tom Baker Cancer Centre, Calgary, CanadaAbstract: Hodgkin lymphoma is one of the most common cancers of adolescence and young adulthood. Most patients are cured of their disease, with very high cure rates in early stage disease and improving rates of cure even in those who present with advanced stage disease. Upfront therapy often involves chemotherapy and radiation therapy; with improving cure rates, acute and late effects of therapy are informing newer treatment protocols to avoid toxicities. Those children and adolescents with refractory or relapsed disease have lower rates of cure and generally warrant more intensive therapy. High-dose chemotherapy and autologous stem cell transplantation is often administered in such cases. This intensive intervention can be curative, but carries additional risks in the short and long term. This review includes a discussion of both transplant and non-transplant therapy for relapsed disease, commonly employed conditioning regimens, acute and late toxicities of therapy, as well as quality of life data. In addition, newer approaches to therapy for Hodgkin lymphoma are reviewed, with a focus on how such novel therapies might relate to high-dose chemotherapeutic approaches.Keywords: Hodgkin lymphoma, adolescents, high-dose chemotherapy, autologous stem cell transplant

    High-intensity focused ultrasound (synonyms FUS and HIFU) under magnetic resonance imaging (MRI) guidance (synonyms MRgFUS and MR-HIFU) is a completely non-invasive technology for accurate thermal ablation of a target tissue while neighboring tissues and organs are preserved. The combination of FUS with MRI for planning, (near) real-time monitoring and outcome assessment of treatment markedly enhances the safety of the procedure. The MRgFUS procedure is clinically established in particular for the treatment of symptomatic uterine fibroids, followed by palliative ablation of painful bone metastases. Furthermore, promising results have been shown for the treatment of adenomyosis, malignant tumors of the prostate, breast and liver and for various intracranial applications, such as thermal ablation of brain tumors, functional neurosurgery and transient disruption of the blood-brain barrier.

The MR-based evaluation of HIFU treatment is most often restricted to contrast-enhanced T1 -weighted imaging, while it has been shown that the non-perfused volume may not reflect the extent of nonviable tumor tissue after HIFU treatment. There are multiple studies in which more advanced MRI methods were assessed for their suitability for the evaluation of HIFU treatment. While several of these methods seem promising regarding their sensitivity to HIFU-induced tissue changes, there is still ample room for improvement of MRI protocols for HIFU treatment evaluation. In this review article, we describe the major acute and delayed effects of HIFU treatment. For each effect, the MRI methods that have been-or could be-used to detect the associated tissue changes are described. In addition, the potential value of multiparametric MRI for the evaluation of HIFU treatment is discussed. The review ends with a discussion on future directions for the MRI-based evaluation of HIFU treatment.

    Overweight and obesity have been rising dramatically worldwide and are associated with numerous co-morbidities such as cardiovascular disease (CVD), type 2 diabetes mellitus, hypertension, certain cancers, and sleep apnea. In fact, obesity is an independent risk factor for CVD and CVD risks have also been documented in obese children. The majority of overweight and obese patients who achieve a significant short-term weight loss do not maintain their lower bodyweight in the long term. This may be due to a lack of intensive counseling and support from a facilitating environment including dedicated healthcare professionals such as nutritionists, kinesiologists, and behavior specialists. As a result, there has been a considerable focus on the role of adjunctive therapy such as pharmacotherapy for long-term weight loss and weight maintenance. Beyond an unfavorable risk factor profile, overweight and obesity also impact upon heart structure and function. Since the beginning, the quest for weight loss drugs has encountered warnings from regulatory agencies and the withdrawal from the market of efficient but unsafe medications. Fenfluramine was withdrawn from the market because of unacceptable pulmonary and cardiac adverse effects. Nevertheless, there is extensive research directed at the development of new anti-obesity compounds. The effect of these molecules on CVD risk factors has been studied and reported but information regarding their impact on the cardiovascular system is sparse. Thus, instead of looking at the benefit of weight loss on metabolism and risk factor management, this article discusses the impact of weight loss medications on the cardiovascular system. The potential interaction of available and potential new weight loss drugs with heart function and structure is reviewed.

    Full Text Available This study aimed to analyze the effective tax rate of public companies operating in stock market in Brazil over a period between 2003 and 2013, both to the total effective tax rate (ETRt as the curren (ETRc, seeking to verify evidence of the presence of tax management. This analysis consists of (i to assess whether average tax burden is upper, equal or less than the statutory rate of 34%; (ii verify that the ETR suffered influence of RTT adjustments arising from the introduction of IFRS; (iii identify proxies (size; profitability; inventory; properties, plants and equipment; debt; and deferred tax expenses which may explain the variation in ETR. The results showed that: (i companies have a significantly lower ETR than the statutory tax rate; (ii companies reported a lower ETR on the full adoption of IFRS period; (iii the ETR has relation to size (negative, debt (positive and components of assets (positive; and (iv there are deferral strategies considering the negative sign of deferred taxes in relation to the current ETR. The results confirm the practice of tax management and also demonstrate that the resulting RTT adjustments resulted in a lower tax burden, confirming previous studies that estimated less conservative earnings after the beginning of the convergence process. Finally, we observed that larger companies have a lower tax burden and that in general companies adopt choices that allow the deferral of taxes on income.

  19. Current perspectives on the hormonal control of seed development in Arabidopsis and maize: a focus on auxin.

    The seed represents the unit of reproduction of flowering plants, capable of developing into another plant, and to ensure the survival of the species under unfavorable environmental conditions. It is composed of three compartments: seed coat, endosperm and embryo. Proper seed development depends on the coordination of the processes that lead to seed compartments differentiation, development and maturation. The coordination of these processes is based on the constant transmission/perception of signals by the three compartments. Phytohormones constitute one of these signals; gradients of hormones are generated in the different seed compartments, and their ratios comprise the signals that induce/inhibit particular processes in seed development. Among the hormones, auxin seems to exert a central role, as it is the only one in maintaining high levels of accumulation from fertilization to seed maturation. The gradient of auxin generated by its PIN carriers affects several processes of seed development, including pattern formation, cell division and expansion. Despite the high degree of conservation in the regulatory mechanisms that lead to seed development within the Spermatophytes, remarkable differences exist during seed maturation between Monocots and Eudicots species. For instance, in Monocots the endosperm persists until maturation, and constitutes an important compartment for nutrients storage, while in Eudicots it is reduced to a single cell layer, as the expanding embryo gradually replaces it during the maturation. This review provides an overview of the current knowledge on hormonal control of seed development, by considering the data available in two model plants: Arabidopsis thaliana, for Eudicots and Zea mays L., for Monocots. We will emphasize the control exerted by auxin on the correct progress of seed development comparing, when possible, the two species.

    Spontaneous self-focusing of ion beam with high current density (J{sub c} ∼ 2 mA/cm{sup 2}, I{sub b} ∼ 65 mA) in low energy region (∼150 eV) is observed in a hydrogen ion beam extracted from an ordinary bucket type ion source with three electrodes having concave shape (acceleration, deceleration, and grounded electrodes). The focusing appears abruptly in the beam energy region over ∼135–150 eV, and the J{sub c} jumps up from 0.7 to 2 mA/cm{sup 2}. Simultaneously a strong electron flow also appears in the beam region. The electron flow has almost the same current density. Probably these electrons compensate the ion space charge and suppress the beam divergence.

    Re, Anna M.; Capodieci, Agnese; Cornoldi, Cesare

    2015-01-01

    The development of early intervention strategies for children with symptoms of Attention Deficit Hyperactivity Disorder (ADHD) is important because it provides an opportunity to prevent severe problems in the future. The main purpose of this investigation was to determine the efficacy of a group training for the control of attention, working memory and impulsive behaviors, involving 5-year-old children with ADHD symptoms. Twenty-six children with ADHD symptoms and 26 with typical development were randomly divided in two conditions. Thirteen children in each group were assigned to the training condition and the other to the business as usual condition (normal class activity). Children who participated in the intervention showed an improvement in the tasks measuring their control of attention, impulsive behavior, and working memory. Moreover, children with typical development who attended the training also improved their competencies. The results confirm the importance of an early intervention for preschool-age children with ADHD symptoms. PMID:26300836

    2015-07-01

    To support our Lean culture of continuous improvement, we implemented a daily management system designed so critical metrics of operational success were the focus of local teams to drive improvements. We innovated a standardized visual daily management board composed of metric categories of Quality, Time, Inventory, Productivity, and Safety (QTIPS); frequency trending; root cause analysis; corrective/preventive actions; and resulting process improvements. In 1 year (June 2013 to July 2014), eight laboratory sections at Henry Ford Hospital employed 64 unique daily metrics. Most assessed long-term (>6 months), monitored process stability, while short-term metrics (1-6 months) were retired after successful targeted problem resolution. Daily monitoring resulted in 42 process improvements. Daily management is the key business accountability subsystem that enabled our culture of continuous improvement to function more efficiently at the managerial level in a visible manner by reviewing and acting based on data and root cause analysis.

    2013-01-01

    This exploratory study examined the use of two components (small and large groups) of a community-based intervention, the Focused Support Group (FSG) model, to alleviate employment-related stressors in Black women. Participants were assigned to small groups based on occupational status. Groups met for five weekly 3-hr sessions in didactic or small- and large-group formats. Two evaluations following the didactic session and the small and large group sessions elicited information on satisfaction with each of the formats, self-reported change in stress, awareness of interpersonal and sociopolitical issues affecting Black women in the labor force, assessing support networks, and usefulness of specific discussion topics to stress reduction. Results indicated the usefulness of the small- and large-group formats in reduction of self-reported stress and increases in personal and professional sources of support. Discussions on race and sex discrimination in the workplace were effective in overall stress reduction. The study highlights labor force participation as a potential source of stress for Black women, and supports the development of culture- and gender-appropriate community interventions as viable and cost-effective methods for stress reduction.

    Beula M. Magimairaj

    2013-01-01

    Full Text Available Whereas considerable developmental memory research has examined the contributions of short-term memory, processing efficiency, retention duration, and scope of attention to complex memory span, little is known about the influence of controlled attention. The present study investigated the relative influence of three understudied attention mechanisms on the verbal working memory span of school-age children: memory updating; attention focus switching; and sustained attention. Results of general linear modeling revealed that, after controlling for age, only updating accuracy emerged as a significant predictor of verbal working memory span. Memory updating speed (that subsumed attention focus switching speed also contributed but was mediated by age. The results extend the developmental memory literature by implicating the mechanism of memory updating and developmental improvement in speed of attention focus switching and updating as critical contributors to children’s verbal working memory. Theoretically, the results provide substantively new information about the role of domain-general executive attention in children’s verbal working memory.

    2011-01-01

    During the IAU General Assembly in Rio de Janeiro in 2009, the members of Commission 22 established the Working Group on Meteor Shower Nomenclature, from what was formerly the Task Group on Meteor Shower Nomenclature. The Task Group had completed its mission to propose a first list of established meteor showers that could receive officially names. At the business meeting of Commission 22 the list of 64 established showers was approved and consequently officially accepted by the IAU. A two-step process is adopted for showers to receive an official name from the IAU: i) before publication, all new showers discussed in the literature are first added to the Working List of Meteor Showers, thereby receiving a unique name, IAU number and three-letter code; ii) all showers which come up to the verification criterion are selected for inclusion in the List of Established Meteor Showers, before being officially named at the next IAU General Assembly.

  20. New respirator fit test panels representing the current U.S. civilian work force.

    Science.gov (United States)

    Zhuang, Ziqing; Bradtmiller, Bruce; Shaffer, Ronald E

    2007-09-01

    The fit test panels currently used for respirator research, design, and certification are 25-subject panels developed by Los Alamos National Laboratory (LANL) and are based on data from the 1967 and 1968 anthropometric surveys of U.S. Air Force personnel. Military data do not represent the great diversity in face size and shape seen in civilian populations. In addition, the demographics of the U.S. population have changed over the last 30 years. Thus, it is necessary to assess and refine the LANL fit test panels. This paper presents the development of new respirator fit test panels representative of current U.S. civilian workers based on an anthropometric survey of 3,997 respirator users conducted in 2003. One panel was developed using face length and face width (bivariate approach) and weighting subjects to match the age and race distribution of the U.S. population as determined from the 2000 census. Another panel was developed using the first two principal components obtained from a set of 10 facial dimensions (age and race adjusted). These 10 dimensions are associated with respirator fit and leakage and can predict the remaining face dimensions well. Respirators designed to fit these panels are expected to accommodate more than 95% of the current U.S. civilian workers. Both panels are more representative of the U.S. population than the existing LANL panel and may be appropriate for testing both half-masks and full-face piece respirators. Respirator manufacturers, standards development organizations, and government respirator certification bodies need to select the appropriate fit test panel for their particular needs. The bivariate panel is simpler to use than the principal component analysis (PCA) panel and is most similar to the LANL panel currently used. The inclusion of the eight additional facial measurements allows the PCA panel to provide better criteria for excluding extreme face sizes from being used. Because the boundaries of the two new panels are

    Full Text Available Abstract Background Employment rates of long-term ill and disabled people in the UK are low and 2.63 million are on disability-related state benefits. Since the mid-1990 s, UK governments have experimented with a range of active labour market policies aimed to move disabled people off benefits and into work to reduce the risk of poverty and social exclusion. This systematic review asks what employment impact have these interventions had and how might they work better? Methods A systematic review of observational and qualitative empirical studies and systematic reviews published between 2002 and mid-2008 reporting employment effects and/or process evaluations of national UK government interventions focused on helping long-term sick or disabled people (aged 16-64 into the open labour market. This built on our previous systematic review which covered the years 1970 to 2001. Results Searches identified 42 studies, 31 of which evaluated initiatives with an individual focus (improving an individual's employability or providing financial support in returning to work while 11 evaluated initiatives with an environmental focus (directed at the employment environment or changing the behaviour of employers. This paper synthesises evidence from the 31 studies with an individual focus. The use of personal advisors and individual case management in these schemes helped some participants back to work. Qualitative studies, however, revealed that time pressures and job outcome targets influenced advisors to select 'easier-to-place' claimants into programmes and also inhibited the development of mutual trust, which was needed for individual case management to work effectively. Financial incentives can help with lasting transitions into work, but the incentives were often set too low or were too short-term to have an effect. Many of the studies suffered from selection bias into these programmes of more work-ready claimants. Even though these were national

    A possibility of a compact powerful point-like neutron source creation is discussed. Neutron yield of the source based on deuterium-deuterium (D-D) reaction is estimated at the level of 1011 s‑1 (1013 s‑1 for deuterium-tritium reaction). The fusion takes place due to bombardment of deuterium- (or tritium) loaded target by high-current focused deuterium ion beam with energy of 100 keV. The ion beam is formed by means of high-current quasi-gasdynamic ion source of a new generation based on an electron cyclotron resonance (ECR) discharge in an open magnetic trap sustained by powerful microwave radiation. The prospects of proposed generator for neutron tomography are discussed. Suggested method is compared to the point-like neutron sources based on a spark produced by powerful femtosecond laser pulses.

    Full Text Available Mobbing or harassment is now recognized as a phenomenon of high impact on individuals, organizations and society. In Latin America, and specifically in Colombia, has been identified little development of thematic; this is a weakness against the possibilities to know, identify and intervene on this reality, growing in organizations. The objective of this paper is to present the results of theoretical analysis and review of prevention of mobbing in Colombia. The paper is divided into four parts. In the first, the main theoretical elements of the discussion about mobbing are synthesized. In the second, reviewed the legislation on mobbing in Colombia, and that the state has responsibilities for the identification, assessment, prevention and intervention of psychosocial risk factors at work. In a third part, presents and analyzes some measures and procedures existing prevention and intervention. Finally conclusions of the review are presented.

  7. Mechanisms and Kinetics of Environmentally Assisted Cracking: Current Status, Issues, and Suggestions for Further Work

    Mechanisms and kinetics of metal-induced embrittlement, hydrogen-embrittlement, and stress-corrosion cracking are discussed, and long-standing controversies are addressed by reviewing critical observations. Recommendations are also made regarding further work (including repetition of previous work using more advanced measurement and characterisation techniques) that should be carried out in order to resolve some of the contentious issues. The evidence to date suggests that adsorption-based mechanisms, involving weakening of substrate interatomic bonds so that dislocation emission or decohesion is facilitated, accounts for embrittlement in many systems. Embrittling adsorbed species include some metal atoms, hydrogen, and complex ions produced by de-alloying. Other viable mechanisms of embrittlement include those based on (1) dissolution of anodic grain-boundary regions, and (2) decohesion at grain boundaries owing to segregated hydrogen and impurities. The hydrogen-enhanced localised-plasticity mechanism, based on solute hydrogen facilitating dislocation activity in the plastic zone ahead of cracks, makes a contribution in some cases, but is relatively unimportant compared with these other mechanisms for most fracture modes. The film-induced cleavage mechanism, proposed especially for stress-corrosion cracking in systems involving de-alloying at crack tips, is questionable on numerous grounds, and is probably not viable. Rate-controlling processes for environmentally assisted cracking are not well established, except for solid-metal induced embrittlement where surface self-diffusion of embrittling atoms to crack tips controls cracking kinetics. In some systems, adsorption kinetics are probably rate-controlling for liquid-metal embrittlement, hydrogen-environment embrittlement, and stress-corrosion cracking. In other cases, rate-controlling processes could include the rate of anodic or cathodic reactions at and behind crack tips (responsible for producing embrittling

    Effective work functions of refractory metals at temperatures near their melting points were determined by using a direct-current arc. A metal wire connected as the cathode was melted by striking an arc discharge in an argon atmosphere. A melted sphere was formed with a definite emitting area which was calculated from the sphere diameter measured after terminating the arc. Effective work functions were calculated from the Richardson-Dushman equation by using this emission area. The procedure is experimentally advantageous because surface cleanliness of the specimen is not critical, high vacuum is not required, and the anode-cathode spacing is not critical.

  9. Engaging Girls in STEM: A Discussion of Foundational and Current Research on What Works

    2012-08-01

    Diversity in science, technology, engineering, and mathematics (STEM) education and careers occupies center stage in national discussions on U.S. competitiveness in the 21st century. Women constitute roughly half the total workforce in the U.S., but they hold just 25% of mathematical and science jobs and 11% of engineering jobs. Women earn nearly 60% of all bachelors and masters degrees, except in physics, computer science, and engineering, where the percentages are 20-25%. This disparity is even more pronounced at the doctoral level, where women earn fewer than 20% of awarded Ph.D.'s in physics or engineering. However, at the high school level, there is far less gender disparity: both female and male students take comparable advanced physical science and math courses. What, then, accounts for the lack of gender diversity in STEM advanced education and career paths? In fact, there is no consensus even among experts. So, what information and strategies do the EPO community need to know and include as part of designing and implementing programs to encourage more girls and women to engage in STEM for the long term? The panelists will discuss foundational and current research on pressing questions on why these trends exist and what can be done to change them. They will highlight research and evaluation results from programs that are successfully engaging girls in STEM.

    Full Text Available Brain network dysfunction is emerging as a central biomarker of interest in psychiatry, in large part because psychiatric conditions are increasingly seen as disconnection syndromes. Understanding dysfunctional brain network profiles in task-active states provides important information on network engagement in an experimental context. This in turn may be predictive of many of the cognitive and behavioral deficits associated with complex behavioral phenotypes. Here we investigated brain network profiles in youth with obsessive-compulsive disorder (OCD, contrasting them with a group of age-comparable controls. Network interactions were assessed during simple working memory: in particular, we focused on the modulation by the dorsal anterior cingulate cortex (dACC of cortical, striatal and thalamic regions. The focus on the dACC was motivated by its hypothesized role in the pathophysiology of OCD. However, its task-active network signatures have not been investigated before. Network interactions were modeled using psychophysiological interaction, a simple directional model of seed to target brain interactions. Our results indicate that OCD is characterized by significantly increased dACC modulation of cortical, striatal and thalamic targets during working memory, and that this aberrant increase in OCD patients is maintained regardless of working memory demand. The results constitute compelling evidence of dysfunctional brain network interactions in OCD and suggest that these interactions may be related to a combination of network inefficiencies and dACC hyper-activity that has been associated with the phenotype.

    Research about the support needs for and barriers to successful disease management of working adults with diabetes is limited. Our objective was to gain an in-depth understanding of how working adults in Hawaii perceive diabetes, barriers to disease management, and the services needed to keep people healthy and working. From November 2008 through March 2009, we conducted focus group interviews with 74 employed adults with diabetes enrolled in the Hawaii Demonstration to Maintain Independence and Employment project. Responses to questions were analyzed within and across groups to identify recurring themes. A third layer of analysis examined themes across responses to all questions, specifically, how barriers related to identified service needs. Employed participants with diabetes experienced pervasive effects on their lives as a result of the disease, although they interpreted these effects positively or negatively. Barriers to disease management, such as additional health issues, social prejudice, and lack of social support, indicated a need to educate the general public about the disease. Participants identified needing social support from other people with diabetes, psychological support to address the emotional side of diabetes, and coordinated teams of specialists to address medication side effects and other health-related barriers to disease management. Many participants discussed the challenge of integrating diabetes management with work and family responsibilities and the need for monetary support. This study provides insight into how employed adults perceived their disease and what they perceived as challenges to successfully managing diabetes. The findings provide future directions for community and workplace diabetes initiatives.

    The purpose of this study was to identify the current status of operations at community general support centers which provide coordination for elderly care and the correlation of personal traits, work environment and the occupational stress of the staff. Subjects of the study were 251 staff members of community general support centers. The current status of operations at the community general support centers and the personal traits, work environment, effort-remuneration imbalance model (ERI) and general health questionnaire (GHQ) were surveyed. The initial analysis involved a comparison by a chi-square test on: The effort-remuneration ratio (E/R ratio) of personal traits and work environment, risk of over-commitment (OC), and GHQ score. To explore the correlation between the E/R ratio of the three GHQ groups (low, middle and high score groups) and the OC value, one-way analysis of variance was performed. Out of the four basic functions of the community general support centers, 22.0% of the respondents noted that "establishment of a regional, comprehensive/multi-tiered service network" was functioning, and 50.4% of respondents noted that "comprehensive and continuous care management" was functioning. The average effort score was 15.5 +/- 5.3, approximately double the average value of preceding studies. Significant differences found in GHQ scores were related to working hours (pworking hours of 50 h or more" (OR: 10.38, 95% CI: 2.52-42.70), "Unstable employment" (OR: 2.75, 95% CI: 1.22-6.21) and "Anxiety related to task content" (OR: 17.04, 95% CI: 3.57-81.24). Items observed to have significant correlation with OC value risk factors were: "Weekly working hours of 50 h or more" (OR: 8.04, 95% CI: 1.99-32.41) and "Anxiety related to task content" (OR: 4.60, 95% CI: 2.04-10.37). We conclude that the basic functions of the community general support centers are not presently very functional. The stress levels of the community general support center staff are high and

    In the empirical literature on work experience, job tenure, training and earnings, only one previous study has made a distinction between the effects of work experience in the current occupation and work experience in previous ones, and no study has made the distinction with respect to training. Yet it is reasonable to hypothesize that the distinction is important. Using data from the US National Longitudinal Survey of Youth, it is found that the returns to work experience in the current occu...

    Krifka [1993] has suggested that focus should be seen as a means of providing material for a range of semantic and pragmatic functions to work on, rather than as a specific semantic or pragmatic function itself. The current paper describes an implementation of this general idea, and applies it to the interpretation of {\\em only} and {\\em not}.

    Purpose To assist in determining barriers to an oncology career incorporating cancer prevention, the American Society of Clinical Oncology (ASCO) Cancer Prevention Workforce Pipeline Work Group sponsored surveys of training program directors and oncology fellows. Methods Separate surveys with parallel questions were administered to training program directors at their fall 2013 retreat and to oncology fellows as part of their February 2014 in-training examination survey. Forty-seven (67%) of 70 training directors and 1,306 (80%) of 1,634 oncology fellows taking the in-training examination survey answered questions. Results Training directors estimated that ≤ 10% of fellows starting an academic career or entering private practice would have a career focus in cancer prevention. Only 15% of fellows indicated they would likely be interested in cancer prevention as a career focus, although only 12% thought prevention was unimportant relative to treatment. Top fellow-listed barriers to an academic career were difficulty in obtaining funding and lower compensation. Additional barriers to an academic career with a prevention focus included unclear career model, lack of clinical mentors, lack of clinical training opportunities, and concerns about reimbursement. Conclusion Reluctance to incorporate cancer prevention into an oncology career seems to stem from lack of mentors and exposure during training, unclear career path, and uncertainty regarding reimbursement. Suggested approaches to begin to remedy this problem include: 1) more ASCO-led and other prevention educational resources for fellows, training directors, and practicing oncologists; 2) an increase in funded training and clinical research opportunities, including reintroduction of the R25T award; 3) an increase in the prevention content of accrediting examinations for clinical oncologists; and 4) interaction with policymakers to broaden the scope and depth of reimbursement for prevention counseling and

    The discovery of Focused Electron Beam Induced Processing and early applications of this technology led to the possible use of a novel nanogranular material “Koops-GranMat®” using Pt/C and Au/C material. which carries at room temperature a current density > 50 times the current density which high TC superconductors can carry. The explanation for the characteristics of this novel material is given. This fact allows producing novel products for many applications using Dual Beam system having a gas supply and X.Y.T stream data programming and not using GDSII layout pattern control software. Novel products are possible for energy transportation. -distribution.-switching, photon-detection above 65 meV energy for very efficient energy harvesting, for bright field emission electron sources used for vacuum electronic devices like amplifiers for HF electronics, micro-tubes, 30 GHz to 6 THz switching amplifiers with signal to noise ratio >10(!), THz power sources up to 1 Watt, in combination with miniaturized vacuum pumps, vacuum gauges, IR to THz detectors, EUV- and X-Ray sources. Since focusing electron beam induced deposition works also at low energy, selfcloning multibeam-production machines for field emitter lamps, displays, multi-beam - lithography, - imaging, and - inspection, energy harvesting, and power distribution with switches controlling field-emitter arrays for KA of currents but with < 100 V switching voltage are possible. Finally the replacement of HTC superconductors and its applications by the Koops-GranMat® having Koops-Pairs at room temperature will allow the investigation devices similar to Josephson Junctions and its applications now called QUIDART (Quantum interference devices at Room Temperature). All these possibilities will support a revolution in the optical, electric, power, and electronic technology.

    Full Text Available Despite substantial advancement in the understanding and treatment of chronic lymphocytic leukemia (CLL, a standard curative approach does not exist. The choice of treatment is generally based on the existence of biological and genetic factors associated with the prediction of prognosis, individual response to therapy, and duration of remission. About 20% of patients that require treatment have an aggressive disease course and die within a few years, despite early initiation of intensive therapy (poor-risk CLL. Poor-risk CLL can be predicted by the presence of genomic markers, and the quality and duration of response to purine-analogue-based treatment. Within this patient subgroup alternative treatment approaches such as alemtuzumab or new substances such as flavopiridol or IMiDs® should be considered. To date, the only treatment bearing curative potential is allogeneic stem cell transplantation; in contrast to conventional immunochemotherapy, it can provide long-term disease control, even in patients with del 17p or other unfavorable biological and clinical risk factors. The aim of this review was to outline the current strategies for the diagnosis and management of CLL, with a focus on high-risk CLL.

    Full Text Available With the rise of new technologies, citizens can contribute to scientific research via Web 2.0 applications for collecting and distributing geospatial data. Integrating local knowledge, personal experience and up-to-date geoinformation indicates a promising approach for the theoretical framework and the methods of natural hazard analysis. Our systematic literature review aims at identifying current research and directions for future research in terms of Volunteered Geographic Information (VGI within natural hazard analysis. Focusing on both the preparedness and mitigation phase results in eleven articles from two literature databases. A qualitative analysis for in-depth information extraction reveals auspicious approaches regarding community engagement and data fusion, but also important research gaps. Mainly based in Europe and North America, the analysed studies deal primarily with floods and forest fires, applying geodata collected by trained citizens who are improving their knowledge and making their own interpretations. Yet, there is still a lack of common scientific terms and concepts. Future research can use these findings for the adaptation of scientific models of natural hazard analysis in order to enable the fusion of data from technical sensors and VGI. The development of such general methods shall contribute to establishing the user integration into various contexts, such as natural hazard analysis.

    The study evaluated the impact of solution-focused brief therapy (SFBT) group-work on the post-traumatic growth (PTG) of mothers who have a child with ASD. A quasi-experimental design was used in which 43 mothers participated. 18 mothers in 2 SFBT groups (n = 9 in each group) received a 6-session SFBT group therapy while 25 mothers in a control group received no treatment. The Post-traumatic Growth Inventory was used to measure the PTG levels of the participants at baseline, post-treatment and 6-month follow-up assessments. Mothers who attended SFBT group-work reported higher PTG scores both at post-treatment (t = 4.065, p = .001) and 6-month follow-up (t = 2.980, p = .006) assessments. Further investigations to prove whether SFBT in groups can increase the positivity of clients would promote the use of SFBT.

    2004-03-01

    While collaborative (or joint) working between social services and primary healthcare continues to rise up the policy agenda, current policy is not based on sound evidence of benefit to either patients or the wider community. Both sets of practitioners report benefits for their own work from adopting new arrangements for collaboration. The underlying assumption behind much of this activity is that a greater degree of integration provides benefits to both users and their carers, a perspective that at times obscures the issue of resource availability, especially in the form of practical community services such as district nursing and home help. At the present time there is insufficient evidence to demonstrate that formal arrangements for collaborative working (CW) are better than those forged informally between committed individuals or teams. Furthermore, arrangements for CW have not hitherto been widely evaluated in systematic studies with a comparative design and focus on outcomes for users and carers rather than on processes. In this paper we propose a number of process measures for future evaluation of CW: (1) study populations must be comparable; (2) details of how services are actually delivered must be obtained and colocation should not be assumed to mean collaboration; (3) care packages in areas of comparable resources should be examined; (4) both destinational outcomes and user-defined evaluations of benefit should be considered; (5) possible disadvantages of integrated care also need to be actively considered; (6) evaluations should include an economic analysis. Those implementing new policies in Primary Care Trusts have, at present, little sound evidence to guide them in their innovative work. However, they should take the opportunity to rigorously test the advantages and disadvantages of collaboration.

    Full Text Available Aim: The aim of this study is to determine the current trends in the management and surveillance of the NB population secondary to spinal cord injury (SCI or myelomeningocele by certified urologist working in Saudi Arabia and to compare it to the current guidelines. Materials and Methods: A cross-sectional study was conducted using a 12-points questionnaire distributed to urologists working in Saudi Arabia and registered at the Saudi medical association. The assessment and follow-up of upper and lower urinary tract function in neurogenic bladder patients, their optimal frequency and management of related infections were the topics of inquiry. Results: Of the 272 urologists surveyed, 105 responded, yielding a response rate of 38%. Eighty-nine percent of respondents said that ultrasound was their diagnostic tool of choice for upper tract evaluation. Sixty-one percent of respondents said that they would follow their patients with a multichannel urodynamic study. Forty percent of urologists stated that they would treat asymptomatic bacteriuria. Clean intermittent catheterization (CIC was the most common modality chosen for the management of neurogenic bladder in patients with emptying difficulties. Conclusion: This study confirms that most urologists in Saudi Arabia involved with neurogenic bladder management. However, more than one third of the urologists do not have urodynamic machine and only two of the reporting practitioners has a videourodynamic machine. The results emphasize the need for clear guidelines in this field of urology in Saudi Arabia. Highly specialized rehabilitation centers for neurogenic bladder secondary to SCI are required for optimal care and urologist teaching.

    Full Text Available The author details the results of her study of the works of Sergey Sergeyevich Glagolev, a prominent professor of the Moscow Theological Academy. Glagolev’s heritage produces a profound impression by means of its versatility, its original way of looking at diverse problems as well as his unique solutions to the same problems. For this reason, it possesses enduring relevance. Despite this fact, his correspondence is still not well known nor understood. The author focuses on Glagolev’s analysis of the human problem. This choice may be explained by the fact that Sergey Sergeevich considered the problem of man to be the key issue behind the collision of religion and science taking place during the early twentieth century. Glagolev attempted to solve this problem by focusing on certain aspects of the subject: the origin of mankind, the interaction of the spirit and the body, the immortality of the soul, the origin of religion, as well as the way in which religious faith came about. A vital aspect of Glagolev’s treatment of the problem of man is his criticism of Charles Darwin and Darwinism, and thereby of the entire theory of evolution. Glagolev disagreed with the basic premises of this theory as well as with some of its specific conclusions. While opposing the concept of anthropo-genesis, Glagolev formulated his own theory regarding the origins of mankind. Thus, Glagolev viewed the origins and later history of mankind through the prism of his theory of degradation, which allowed him to seamlessly link the biblical narrative of the origins of man with contemporary scientific data. The author concludes that Glagolev was a major influence in the development of Russian theology during the first years of the twentieth century.

    Animal-source foods (ASF) have the potential to enhance the nutritional adequacy of cereal-based diets in low- and middle-income countries, through the provision of high-quality protein and bioavailable micronutrients. The development of guidelines for including ASF in local diets requires an understanding of the nutrient content of available resources. This article reviews food composition tables (FCT) used in sub-Saharan Africa, examining the spectrum of ASF reported and exploring data sources for each reference. Compositional data are shown to be derived from a small number of existing data sets from analyses conducted largely in high-income nations, often many decades previously. There are limitations in using such values, which represent the products of intensively raised animals of commercial breeds, as a reference in resource-poor settings where indigenous breed livestock are commonly reared in low-input production systems, on mineral-deficient soils and not receiving nutritionally balanced feed. The FCT examined also revealed a lack of data on the full spectrum of ASF, including offal and wild foods, which correspond to local food preferences and represent valuable dietary resources in food-deficient settings. Using poultry products as an example, comparisons are made between compositional data from three high-income nations, and potential implications of differences in the published values for micronutrients of public health significance, including Fe, folate and vitamin A, are discussed. It is important that those working on nutritional interventions and on developing dietary recommendations for resource-poor settings understand the limitations of current food composition data and that opportunities to improve existing resources are more actively explored and supported.

    The major factors that lead to national problems in Russia include extremely complex ethnic composition,biased ethnic policies and the impact of globalization.Russian theorists show great concern for these problems and focus on inter-ethnic con-flicts,national separation,state-nation construction,reform of national federalism and status of overseas Russians.The dispute a-mong current various Russian national theories stems largely from different academic standpoints:the state's position,the position of Russian nationality and other minorities' position.In regard to the solution,a challenge faced by Russia is to search for balance between how to promote national blending and how to avoid the fault of the integration model of inter-ethnic politics in USSR.%极其复杂的民族构成、失之偏颇的民族政策与全球化的冲击是导致俄罗斯民族问题的主要因素。对此,俄罗斯理论界与政府表现出极大关注,并把目光聚焦在族际冲突、民族分离、国族建设、民族联邦制改革以及境外俄罗斯人地位等问题上。当前俄罗斯各种民族理论间的争议很大程度上源自不同的学术立场:国家的立场、俄罗斯族的立场以及其他少数民族的立场。在民族问题的治理路径上,如何在促进民族交融与避免苏联族际政治整合模式的失误之间寻找平衡点,是俄罗斯面临的一个挑战。

    To prevent adverse long-term effects, children who suffer from posttraumatic stress symptoms (PTSS) need treatment. Trauma-focused cognitive behavioral therapy (TF-CBT) is an established treatment for children with PTSS. However, alternatives are important for non-responders or if TF-CBT trained therapists are unavailable. Eye movement desensitization and reprocessing (EMDR) is a promising treatment for which sound comparative evidence is lacking. The current randomized controlled trial investigates the effectiveness and efficiency of both treatments. Forty-eight children (8-18 years) were randomly assigned to eight sessions of TF-CBT or EMDR. The primary outcome was PTSS as measured with the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA). Secondary outcomes included parental report of child PTSD diagnosis status and questionnaires on comorbid problems. The Children's Revised Impact of Event Scale was administered during the course of treatment. TF-CBT and EMDR showed large reductions from pre- to post-treatment on the CAPS-CA (-20.2; 95% CI -12.2 to -28.1 and -20.9; 95% CI -32.7 to -9.1). The difference in reduction was small and not statistically significant (mean difference of 0.69, 95% CI -13.4 to 14.8). Treatment duration was not significantly shorter for EMDR (p = 0.09). Mixed model analysis of monitored PTSS during treatment showed a significant effect for time (p EMDR are effective and efficient in reducing PTSS in children.

    Full Text Available The article is focused on the current state, trends and contradictions in organization of the work of the Russian traffic police subdivisions of the Ministry of Interior, following the requirements of the President regarding education of law-abiding citizens. After the road accident that had occurred in Khabarovsk region on August 5, 2015, when 68 people were injured, 15 people died, Vladimir Putin conducted a session of the Government of the Russian Federation. At the session, the President assigned the task to develop additional measures of safety on the roads. The complex plan, proposed by I. Shuvalov and aimed at reducing deaths on the roads, includes some different aspects: interaction with information agencies for publishing the data on dangerous sections of roads; strengthening of requirements to organizations engaged in transporting citizens; the use of helicopters to provide medical aid for victims of traffic accidents. The First Deputy Chairman of the Government of the Russian Federation paid special attention to education of road users, introduction of norms of driver’s behavior, emergence of the term «dangerous driving» and strengthening of the responsibility for driving while intoxicated. For many years, the educational function has been assigned to police officers, namely to the traffic police. However, in some regions of the Russian Federation there is a reduction of police regular staff officers, including the State Inspection for road traffic safety of territorial subdivisions of the Ministry of Interior of the Russian Federation.

    Studies of occupational low back pain (OLBP) have shown that return to work after injury is influenced by workers' concerns and expectations; however, these theoretical constructs have not been explored. The specific aim of this study was to identify themes related to self-efficacy and outcome expectancy for returning to work using qualitative research methods. Twenty-eight individuals who recently returned to work (work (n = 23) were referred by their physiotherapists and interviewed to provide more immediate accounts of their concerns and experiences. Notes and recordings from both sources were searched for utterances describing beliefs about self-efficacy or outcome expectancy for returning to work. Two primary self-efficacy constructs emerged: self-efficacy for resuming physical activity and self-efficacy for resuming work. Self-efficacy for resuming physical activity included 8 sub-domains: lift, carry, sit, stand, push/pull, bend, climb, and reach. Self-efficacy for resuming work included 3 sub-domains: pain control, obtaining help, and meeting job demands. Outcome expectancy included four sub-domains: financial/job security, re-injury, workplace support, and self-image. Hesitation to return to work after OLBP involves not only concerns about pain and re-injury, but also the perceived ability to perform physical tasks, meet role expectations, obtain workplace support, and maintain job security.

    The aim of this study was to present, evaluate and propose a tool for the assessment of psychosocial working conditions in epidemiological studies. A referent group of the large epidemiological study, the MUSIC-Norrtälje study of musculoskeletal disorders, was used. The respondents were 950 working persons (585 female and 365 male). Self-administered questionnaire and personal interview were used. The responses were subjected to factor analysis. The resulting model had components generated from the demand-control-support model and action theory. The result supported the use of different aspects of psychological job demands. The interview data seemed to be more related to factual exposure and the questionnaire data more to individual perception. The usefulness of the model was supported by associations between the model and psychosomatic symptoms and sleep disturbances. A combination of interview and questionnaire increases the possibility of interpreting the association between working conditions and health and may provide a more effective basis for interventions.

    The purpose of this study was to examine the support activities provided for occupational health nurses aimed at improving psychosocial working environments, related knowledge and skills, and learning environments as well as associations among these factors. In addition, we aimed to create correlated factor models to describe the support activities in order to identify ways to promote these activities among occupational health nurses. An anonymous mail-based questionnaire survey was conducted of occupational health nurses who were members of the Japan Society for Occupational Health and belonged to enterprises or independent health insurance societies. Among 356 returned questionnaires (response rate: 46.4%), all the main items were answered in 329 (valid response rate: 92.4%), and these questionnaires were analyzed. Factor analysis was performed for the seven items pertaining to support activities for the improvement of psychosocial working environments and models of each factor of the support activities were developed using covariance structure analysis. In the factor analysis, [Clarifying a stress-related situation and providing advice] and [Facilitating workplace involvement] were identified as support-related factors. The mean implementation rates for these approaches were approximately 50 to 80%, and less than 40%, respectively. [Clarifying a stress-related situation and providing advice] was associated with skills of "providing superiors with explanations to enhance their understanding" and "collecting and analyzing stress survey results by department", and knowledge of "personal stress questionnaires" and "common stress factors in working environments". The above-mentioned knowledge and skills were associated with self-learning of "examining and reporting daily activities for the improvement of working environments" and "reviewing related papers". [Facilitating workplace involvement] was associated with skills of "indirectly supporting discussions led by

    This study aimed to understand the current scenario of voluntary vaccination and the factors influencing its coverage among 18-month-old children of Takatsuki City, Japan. Based on 1167 parents responses, we found that voluntary vaccination coverage rates were low when compared with routine vaccination rates. The children who were not the first born of the family and who had young and poorly educated parents were less likely to receive voluntary vaccination. Japanese government-supported vaccines, such as Haemophilus influenzae type b and pneumococcal vaccine, had a higher coverage than the vaccines for which parents had to bear the entire vaccination cost. Furthermore, it was found that mass communication media and family pediatricians were effective means to disseminate voluntary vaccination-related information. We envisage that an active participation of medical professionals, easy access to vaccinations, and mass awareness programs will increase voluntary vaccination coverage in Takatsuki.

    Developed to replace organophosphate and carbamate insecticides, neonicotinoids are structurally similar to nicotine. The three main neonicotinoid insecticides, imidacloprid, clothianidin, and thiamethoxam, are being re-evaluated by Health Canada's Pest Management Regulatory Agency (PMRA). An important aspect of the re-evaluation is the potential for effects in non-target organisms, including aquatic organisms. Leaching into surface waters is one of the major concerns surrounding extensive use of neonicotinoids, especially in close proximity to water bodies. The PMRA has classified IMI as 'persistent' with a 'high' leaching potential. Globally, neonicotinoids have been detected in a variety of water bodies, typically at concentrations in the low μg/L range. While IMI has been included in some monitoring exercises, there are currently very few published data for the presence of CLO and THM in Canadian water bodies. The majority of neonicotinoid toxicity studies have been conducted with IMI due to its longer presence on the market and high prevalence of use. Aquatic insects are particularly vulnerable to neonicotinoids and chronic toxicity has been observed at concentrations of IMI below 1 μg/L. Acute toxicity has been reported at concentrations below 20 μg/L for the most sensitive species, including Hyalella azteca, ostracods, and Chironomus riparius. Fish, algae, amphibians, and molluscs are relatively insensitive to IMI. However, the biological effects of THM and CLO have not been as well explored. The Canadian interim water quality guideline for IMI is 0.23 μg/L, but there is currently insufficient use, fate, and toxicological information available to establish guidelines for CLO and THM. Based on concentrations of neonicotinoids reported in surface waters in Canada and globally, there is potential for aquatic invertebrates to be negatively impacted by neonicotinoids. Therefore, it is necessary to address knowledge gaps to inform decisions around guidelines

  3. Delphinid systematics and biogeography with a focus on the current genus Lagenorhynchus: Multiple pathways for antitropical and trans-oceanic radiation

    KAUST Repository

    Banguera Hinestroza, Eulalia

    2014-11-01

    The six species currently classified within the genus Lagenorhynchus exhibit a pattern of antitropical distribution common among marine taxa. In spite of their morphological similarities they are now considered an artificial grouping, and include both recent and the oldest representatives of the Delphinidae radiation. They are, therefore, a good model for studying questions about the evolutionary processes that have driven dolphin speciation, dispersion and distribution. Here we used two different approaches. First we constructed a multigenic phylogeny with a minimum amount of missing data (based on 9 genes, 11,030 bp, using the 6 species of the genus and their closest relatives) to infer their relationships. Second, we built a supermatrix phylogeny (based on 33 species and 27 genes) to test the effect of taxon sampling on the phylogeny of the genus, to provide inference on biogeographic history, and provide inference on the main events shaping the dispersion and radiation of delphinids. Our analyses suggested an early evolutionary history of marine dolphins in the North Atlantic Ocean and revealed multiple pathways of migration and radiation, probably guided by paleoceanographic changes during the Miocene and Pliocene. L. acutus and L albirostris likely shared a common ancestor that arose in the North Atlantic around the Middle Miocene, predating the radiation of subfamilies Delphininae, Globicephalinae and Lissodelphininae.

  4. Observation of Muon Neutrino Charged Current Events in an Off-Axis Horn-Focused Neutrino Beam Using the NOvA Prototype Detector

    The NOνA is a long base-line neutrino oscillation experiment. It will study the oscillations between muon and electron neutrinos through the Earth. NOνA consists of two detectors separated by 810 km. Each detector will measure the electron neutrino content of the neutrino (NuMI) beam. Differences between the measurements will reveal details about the oscillation channel. The NOνA collaboration built a prototype detector on the surface at Fermilab in order to develop calibration, simulation, and reconstruction tools, using real data. This 220 ton detector is 110 mrad off the NuMI beam axis. This off-axis location allows the observation of neutrino interactions with energies around 2 GeV, where neutrinos come predominantly from charged kaon decays. During the period between October 2011 and April 2012, the prototype detector collected neutrino data from 1.67 × 1020 protons on target delivered by the NuMI beam. This analysis selected a number of candidate charged current muon neutrino events from the prototype data, which is 30% lower than predicted by the NOνA Monte Carlo simulation. The analysis suggests that the discrepancy comes from an over estimation of the neutrino flux in the Monte Carlo simulation, and in particular, from neutrinos generated in charged kaon decays. The ratio of measured divided by the simulated flux of muon neutrinos coming from charged kaon decays is: 0.70+0.108 -0.094. The NOνA collaboration may use the findings of this analysis to introduce a more accurate prediction of the neutrino flux produced by the NuMI beam in future Monte Carlo simulations.

    Although gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by human immunodeficiency virus (HIV) infection, few test for HIV at regular intervals. Smartphone apps may be an ideal tool to increase regular testing among MSM. However, the success of apps to encourage regular testing among MSM will depend on how frequently the apps are downloaded, whether they continue to be used over months or years, and the degree to which such apps are tailored to the needs of this population. The primary objectives of this study were to answer the following questions. (1) What features and functions of smartphone apps do MSM believe are associated with downloading apps to their mobile phones? (2) What features and functions of smartphone apps are most likely to influence MSM's sustained use of apps over time? (3) What features and functions do MSM prefer in an HIV testing smartphone app? We conducted focus groups (n=7, with a total of 34 participants) with a racially and ethnically diverse group of sexually active HIV-negative MSM (mean age 32 years; 11/34 men, 33%, tested for HIV ≥10 months ago) in the United States in Miami, Florida and Minneapolis, Minnesota. Focus groups were digitally recorded, transcribed verbatim, and deidentified for analysis. We used a constant comparison method (ie, grounded theory coding) to examine and reexamine the themes that emerged from the focus groups. Men reported cost, security, and efficiency as their primary reasons influencing whether they download an app. Usefulness and perceived necessity, as well as peer and posted reviews, affected whether they downloaded and used the app over time. Factors that influenced whether they keep and continue to use an app over time included reliability, ease of use, and frequency of updates. Poor performance and functionality and lack of use were the primary reasons why men would delete an app from their phone. Participants also shared their preferences for an app to

    2002-01-01

    The aim was to study the psychometric properties of the Swedish version of the Chronic Pain Coping Inventory. The material consisted of a group of 100 subjects recruited from a large population study. Pain status and the absence of pain-related sick leave during the previous year conditioned inclusion. Another group comprised 160 patients on the long-term sick list and who had been referred to a multidisciplinary pain clinic for evaluation. The psychometric properties in terms of internal consistency of the scales were good or very good for all scales of behaviour-focused pain coping. Use of the strategies "Guarding", "Resting", "Asking for assistance", "Relaxation", "Task persistence", "Coping self-statements" and "Seeking social support" was significantly related to vocational capability. "Guarding". "Asking for assistance", "Relaxation", "Exercise and stretch" and "Coping self-statements" increased in parallel to increasing pain from localized to intermediate or widespread. No gender difference was found in cases reporting more pronounced pain.

    During private well testing in 1990-1991, carbon tetrachloride was identified in the groundwater at several locations in the town of Navarre, Kansas, at levels exceeding the Kansas Tier 2 level and U.S. Environmental Protection Agency (EPA) maximum contaminant level (MCL) of 5.0 μg/L. Several subsequent investigations through 2006 evaluated the concentrations and distribution of carbon tetrachloride in groundwater. This work included the identification of the contaminant sources (Argonne 2007). The history of activities to address the contamination in soil and groundwater is summarized in Table 1.1. The most recent studies, conducted by the Kansas Department of Health and Environment (KDHE), include a brownfields investigation initiated in 2013 (Phase I) and continuing in early 2014 (Phase II), as well as private well testing.

    Despite impressive decreases in under-five mortality, progress in reducing maternal and neonatal mortality in Tanzania has been slow. We present an evaluation of a cadre of maternal, newborn, and child health community health worker (MNCH CHW) focused on preventive and promotive services during the antenatal and postpartum periods in Morogoro Region, Tanzania. Study findings review the effect of several critical design elements on knowledge, time allocation, service delivery, satisfaction, and motivation. A quantitative survey on service delivery and knowledge was administered to 228 (of 238 trained) MNCH CHWs. Results are compared against surveys administered to (1) providers in nine health centers (n = 88) and (2) CHWs (n = 53) identified in the same districts prior to the program's start. Service delivery outputs were measured by register data and through a time motion study conducted among a sub-sample of 33 randomly selected MNCH CHWs. Ninety-seven percent of MNCH CHWs (n = 228) were interviewed: 55% male, 58% married, and 52% with secondary school education or higher. MNCH CHWs when compared to earlier CHWs were more likely to be unmarried, younger, and more educated. Mean MNCH CHW knowledge scores were <50% for 8 of 10 MNCH domains assessed and comparable to those observed for health center providers but lower than those for earlier CHWs. MNCH CHWs reported covering a mean of 186 households and were observed to provide MNCH services for 5 h weekly. Attendance of monthly facility-based supervision meetings was nearly universal and focused largely on registers, yet data quality assessments highlighted inconsistencies. Despite program plans to provide financial incentives and bicycles for transport, only 56% of CHWs had received financial incentives and none received bicycles. Initial rollout of MNCH CHWs yields important insights into addressing program challenges. The social profile of CHWs was not significantly associated with knowledge or

    1996-03-01

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this approach, EM developed a management structure and principles that led to creation of specific focus areas. These organizations were designed to focus scientific and technical talent throughout DOE and the national scientific community on major environmental restoration and waste management problems facing DOE. The focus area approach provides the framework for inter-site cooperation and leveraging of resources on common problems. After the original establishment of five major focus areas within the Office of Technology Development (EM-50), the Nuclear Materials Stabilization Task Group (NMSTG, EM-66) followed EM-50`s structure and chartered the Plutonium Focus Area (PFA). NMSTG`s charter to the PFA, described in detail later in this book, plays a major role in meeting the EM-66 commitments to the Defense Nuclear Facilities Safety Board (DNFSB). The PFA is a new program for FY96 and as such, the primary focus of revision 0 of this Technology Summary is an introduction to the Focus Area; its history, development, and management structure, including summaries of selected technologies being developed. Revision 1 to the Plutonium Focus Area Technology Summary is slated to include details on all technologies being developed, and is currently planned for release in August 1996.

    Full Text Available La violencia en la actualidad es un fenómeno sociocultural que alcanza diversos ámbitos. Uno de ellos es el lugar de trabajo. Aunque este último en general ha sido considerado tradicionalmente como un ambiente relativamente benigno y libre de violencia, nuestra concepción del problema ha evolucionado hacia el concepto de que la violencia laboral no es un problema individual episódico, sino que es un tema estructural estratégico enraizado en factores sociales económicos culturales y organizacionales más amplios, que ha comenzado a preocupar a la sociedad por sus altos costos en salud y en la economía de los países. La mujer, como parte del mundo laboral, está propensa a sufrir violencia de diversa índole, siendo frecuente por sus características de género el acoso sexual, la inequidad salarial y el "mobbing", definido como acoso moral. El presente trabajo es una revisión que aborda la violencia laboral que sufre la mujer y su implicación para la enfermería como profesión típicamente femenina.At present time, violence is a socio-cultural phenomena that affects different environments. One of them is the workplace. Although the latter in general has traditionally been viewed as a relatively benign and violence-free environment, our understanding has grown that violence at work is not just an episodic, individual problem, but a structural, strategic issue rooted in wider social economic, organizational and cultural factors that worries society because of its high costs in health and in the economy of countries. Women, as part of the working population, are bound to suffer violence at workplace of various types, being frequent, because of their gender characteristics, salary inequity, sexual harassment and "mobbing". The present work is a revision that issues violence at workplace and its implications for nursing, as a typical feminine profession.

    Impairments of working memory (WM) performance are frequent concomitant symptoms in several psychiatric and neurologic diseases. Despite the great advance in treating the reduced WM abilities in patients suffering from, e.g., Parkinson’s and Alzheimer’s disease by means of transcranial direct current stimulation (tDCS), the exact neurophysiological underpinning subserving these therapeutic tDCS-effects are still unknown. In the present study we investigated the impact of tDCS on performance i...

  16. Advancing current approaches to disease management evaluation: capitalizing on heterogeneity to understand what works and for whom.

    Evaluating large-scale disease management interventions implemented in actual health care settings is a complex undertaking for which universally accepted methods do not exist. Fundamental issues, such as a lack of control patients and limited generalizability, hamper the use of the 'gold-standard' randomized controlled trial, while methodological shortcomings restrict the value of observational designs. Advancing methods for disease management evaluation in practice is pivotal to learn more about the impact of population-wide approaches. Methods must account for the presence of heterogeneity in effects, which necessitates a more granular assessment of outcomes. This paper introduces multilevel regression methods as valuable techniques to evaluate 'real-world' disease management approaches in a manner that produces meaningful findings for everyday practice. In a worked example, these methods are applied to retrospectively gathered routine health care data covering a cohort of 105,056 diabetes patients who receive disease management for type 2 diabetes mellitus in the Netherlands. Multivariable, multilevel regression models are fitted to identify trends in clinical outcomes and correct for differences in characteristics of patients (age, disease duration, health status, diabetes complications, smoking status) and the intervention (measurement frequency and range, length of follow-up). After a median one year follow-up, the Dutch disease management approach was associated with small average improvements in systolic blood pressure and low-density lipoprotein, while a slight deterioration occurred in glycated hemoglobin. Differential findings suggest that patients with poorly controlled diabetes tend to benefit most from disease management in terms of improved clinical measures. Additionally, a greater measurement frequency was associated with better outcomes, while longer length of follow-up was accompanied by less positive results. Despite concerted efforts to adjust

    Cumulative exposure to work-related traumatic events (CE) is a foreseeable risk for psychiatric disorders in first responders (FRs). Our objective was to examine the impact of work-related CE that could serve as predictor of posttraumatic stress disorder (PTSD) and/or depression in FRs. Cross-sectional examination of previous CE and past-month PTSD outcomes and depression in 209 FRs. Logistic (probable PTSD; probable depression) and Poisson regressions (PTSD score) of the outcomes on work-related CE indexes, adjusting for demographic variables. Differences across occupational groups were also examined. Receiver operating characteristic analysis determined the sensitivity and specificity of CE indexes. All indexes were significantly and differently associated with PTSD; associations with depression were non-significant. The index capturing the sheer number of different incidents experienced regardless of frequency ('Variety') showed conceptual, practical and statistical advantages compared to other indexes. In general, the indexes showed poor to fair discrimination accuracy. Work-related CE is specifically associated with PTSD. Focusing on the variety of exposures may be a simple and effective strategy to predict PTSD in FRs. Further research on sensitivity and specificity of exposure indexes, preferably examined prospectively, is needed and could lead to early identification of individuals at risk.

    Though there are a number of studies investigating the career choices of physicians, there are only few concerning doctors' choices of workplace. A random sample (N=7758) of physicians licensed in Finland during the years 1977-2006 was surveyed. Respondents were asked: "To what extent did the following motives affect your choice of your current workplace?" Respondents were grouped based on several background variables. The groups were used as independent variables in univariate analysis of covariance (ANCOVA). The factors Good workplace, Career and professional development, Non-work related issues, Personal contacts and Salary were formed and used as dependent variables. There were significant differences between groups of physicians, especially in terms of gender, working sector and specialties. The association of Good workplace, Career and professional development, and Non-work related issues with the choice of a workplace significantly decreased with age. Female physicians were more concerned with Career and professional development and Non-work related issues. Since more females are entering the medical profession and there is an ongoing change of generations, health care organizations and policy makers need to develop a new philosophy in order to attract physicians. This will need to include more human-centric management and leadership, better possibilities for continuous professional development, and more personalized working arrangements depending on physician's personal motives.

    CERN Multimedia

    Was used for the AA (antiproton accumulator). Making an antiproton beam took a lot of time and effort. Firstly, protons were accelerated to an energy of 26 GeV in the PS and ejected onto a metal target. From the spray of emerging particles, a magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet.For a million protons hitting the target, just one antiproton was captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 -, three hundred thousand million - antiprotons.

  1. Analysis of Planar E+I and ER+I Transformers for Low-Voltage High-Current DC/DC Converters with Focus on Winding Losses and Leakage Inductance

    In this paper an analysis of two planar transformers designed for high-current switching applications is presented. Typical converter application is represented by fuel and electrolyser cell converters. The transformer designs are based on E+I and ER+I planar cores while the analysis focuses...... on winding resistance and leakage inductances which represent the main concerns related to low-voltage high-current applications. The PCB winding design has a one to one turn ratio with no interleaving between primary and secondary windings. The main goal was to determine if ER planar core could provide...... a significant advantage in terms of winding losses compared to planar E cores. Results from finite element analysis highlight that low frequency winding resistance is lower for the ER core since it is dominated by the lower mean turn length however, as the AC-resistance becomes dominating the winding eddy...

  2. [Evidence of work-related musculo-skeletal disorders of the upper extremities and current methods of risk assessment: can Charlie Chaplin give us any suggestions in "modern times"].

    Apostoli, P; Sala, Emma

    2009-01-01

    in some sequences of the film "Modern Times" Chaplin is clearly involved in activities at high risk for work-related musculo-skeletal disorders of the upper extremities (UEWMSDs), but evidence and perception of any complaint are not evident. To evaluate the extent of the biomechanical risk using current risk assessment methods and discuss the possible reasons for lack of complaints. we made an analysis using six of the current methods for ergonomic risk assessment (State of Washington, check list OCRA, HAL by ACGIH, RULA Strain Index, OREGE). All the methods applied demonstrated high-to-very high levels of biomechanical risk for the upper extremities, with evident psychic effects but without apparent musculo-skeletal disorders. The discrepancy between evident psychological disorders ad apparent absence of UEWMSDs are discussed as being due to either: an artistic choice by Charlie Chaplin who focused on the aspects thought to be more immediately and easily comic; the short duration of the physical load exertion; or because of a different perception of muscular work and fatigue that was also typical until the 1970's and 1980's, which also confirmed the principles and practices of our preventive and medical disciplines at that time.

    We posit the concept of Mobility Work to describe efforts of moving about people and things as part of accomplishing tasks. Mobility work can be seen as a spatial parallel to the concept of articulation work proposed by the sociologist Anselm Strauss. Articulation work describes efforts...... of coordination necessary in cooperative work, but focuses, we argue, mainly on the temporal aspects of cooperative work. As a supplement, the concept of mobility work focuses on the spatial aspects of cooperative work. Whereas actors seek to diminish the amount of articulation work needed in collaboration...... by constructing Standard Operation Procedures (SOPs), actors minimise mobility work by constructing Standard Operation Configurations (SOCs). We apply the concept of mobility work to the ethnography of hospital work, and argue that mobility arises because of the need to get access to people, places, knowledge and...

  4. Impact of mechanical stress on gate tunneling currents of germanium and silicon p-type metal-oxide-semiconductor field-effect transistors and metal gate work function

    2008-03-01

    Uniaxial four-point wafer bending stress-altered gate tunneling currents are measured for germanium (Ge)/silicon (Si) channel metal-oxide-semiconductor field-effect transistors (MOSFETs) with HfO2/SiO2 gate dielectrics and TiN/P+ poly Si electrodes. Carrier separation is used to measure electron and hole currents. The strain-altered hole tunneling current from the p-type inversion layer of Ge is measured to be ˜4 times larger than that for the Si channel MOSFET, since the larger strain-induced valence band-edge splitting in Ge results in more hole repopulation into a subband with a smaller out-of-plane effective mass and a lower tunneling barrier height. The strain-altered electron tunneling current from the metal gate is measured and shown to change due to strain altering the metal work function as quantified by flatband voltage shift measurements of Si MOS capacitors with TaN electrodes.

    把调节焦点理论和调节匹配理论引入领导语言框架研究领域,探讨领导者语言框架风格及其对下属工作态度的影响机理.基于调节焦点理论,通过一个定性分析对促进型和防御型两种领导语言框架风格进行探讨;基于调节匹配理论,运用实验研究方法分析并验证领导语言框架风格与下属特质调节焦点的匹配时下属工作态度影响的作用机理.研究结果表明,对特质促进型调节焦点的下属而言,领导促进型语言框架更能促进其积极的工作态度,而对特质防御型调节焦点的下属而言.领导防御型语言框架更能促进其积极的工作态度.%This paper introduces regulatory focus theory and regulatory fit theory to the research field of leader's linguistic framing and probes into leader's linguistic framing and its influence on followers' work attitude. First, two leader's linguistic framing styles, namely promotion linguistic framing and prevention linguistic framing were identified based on regulatory focus theory and by a qualitative method. Then, drawing on regulatory fit theory and using an experiment method, this paper theoretically proposes and empirically verifies that followers' work attitudes are motivated by the fitness between their chronic regulatory focus and their leaders' linguistic framing. The research results reveal that for promotion-focused followers, their leaders' promotion linguistic framing is more effective for stimulating their positive work attitudes and that for prevention-focused followers, their leaders' prevention linguistic framing is more effective for stimulating their positive work attitudes. This paper concludes by discussing its main findings, theoretical and practical contributions and the limitations in this study.

    In 1936, geologic work related to the Tertiary System in western Saudi Arabia began with a study of the Umm Gerad barite deposit by K. S. Twitchell. In 1944, a study focusing specifically on Tertiary rocks was conducted by Steineke and others near Jiddah. Small-scale mapping of Tertiary sequences began in 1950 in southwestern Saudi Arabia and later in northern 3audi Arabia as part of the Kingdom's early mapping program. These studies were part of a larger program being directed by the Government of Saudi Arabia in connection with mineral resource investigations. In the mid- to late-1960's, the Bureau de Recherches Geologiques et Minieres discovered mineralized Tertiary rocks al Jabal Dhaylan and began a study, which continues to the present, of both the Tertiary rocks and the mineralization. Following a number of early local studies, in 1973 the U.S. Geological Survey began detailed study of the Tertiary layered rocks along the Red Sea coastal plain south of Jiddah. More recently, Riofinex and Seltrust have been exploring for selected commodities in Tertiary sequences of northwestern Saudi Arabia and the Red Sea coastal plain. Results of these studies, including work by the Saudi Arabian Directorate General of Mineral Resources and the Saudi government agency preceding it, are summarized in this report. Characteristics of the Tertiary rocks south of lat 23? N. and the Tertiary mineral deposits of western Saudi Arabia are also summarized. Recommendations are made for future geologic studies and mineral assessment of the Tertiary rocks of western Saudi Arabia.

    Polycrystalline Cu(In,Ga)Se{sub 2} films (CIGSe) show substantial local variations of properties not only in regime of 10-100 nm but also in the scale length of few microns. We have analyzed optoelectronic properties of CIGSe heterodiodes by confocal luminescence and focused light beam induced currents (LBIC) versus temperature and excitation level with < 1 {mu}m lateral resolution and we observe a strong dependence of the size of local patterns on excitation flux and a considerable dependence of the yield and the spectral shape of luminescence and of microscopic LBI currents on temperature. From experiments we derive activation energies for rates of non-radiative recombination of (2-7) meV and for minority carrier mobilities of about (60-70) meV. These energies are compared with local variations of band edges resulting from potential fluctuations which are formulated after an approach from literature and which has been fitted to experimental shifts of PL peaks and squeezing of PL spectra versus excitation flux. We estimate tunnel barriers for radiative transitions of trapped electrons of about (30-70) meV. Correlating our different results we attribute the activation energy for minority transport in CIGSe reflecting local variations of the conduction band edge mainly to spatial fluctuations of the optical band gap as a consequence of spatially varying elemental composition, and to variations of splitting of the quasi-Fermi levels introduced by spatially varying defect densities.

    The MightyMedic (Multidisciplinary International Group for Hemapheresis TherapY and MEtabolic DIsturbances Contrast) Working Group has been founded in 2013. The leading idea was to establish an international network of interdisciplinary nature aimed at working to cross national borders research projects, clinical trials, educational initiatives (meetings, workshops, summer schools) in the field of metabolic diseases, namely hyperlipidemias, and diabetes, preventive cardiology, and atherosclerosis. Therapeutic apheresis, its indications and techniques, is a parallel field of investigation. The first on-line survey of the Group has been completed in the first half of 2014. The survey included # 24 Centers in Italy, Germany, Greece, UK, Sweden, Japan and USA. Relevant data have been collected on current practice in diagnosis, therapy and follow-up of dyslipidemias. 240 subjects with hyperlipidemia and treated with lipoprotein apheresis have been reported in the survey, but a large percentage of patients (35%) who could benefit from this therapeutic option are still treated by conventional drug approach. Genetic molecular diagnosis is performed in only 33% of patients while Lipoprotein(a) (Lp(a)) is included in cardiovascular disease risk assessment in 71% of participating Centers. New detailed investigations and prospective multicenter studies are needed to evaluate changes induced by the impact of updated indications and strategies, as well as new treatment options, targeting standardization of therapeutic and diagnostic approaches.

    As a result of the recently mandated work-hour restrictions, it has become more difficult to provide 24-hour intensive care unit (ICU) in-house coverage by the general surgical residents. To assess the current state of providing appropriate continuous care to surgical critical care patients during the era of resident work-hour constraints, a national survey was conducted by the Association of Program Directors of Surgery. The results revealed that 37 per cent of programs surveyed have residents other than general surgery housestaff providing cross-coverage and writing orders for surgical ICU patients. Residents in emergency medicine, anesthesia, family medicine, otorhinolaryngology, obstetrics/gynecology, internal medicine, urology, and orthopedic surgery have provided this cross-coverage. Some found it necessary to use physician extenders (i.e., nurse practitioners or physician assistants), thereby decreasing the burden of surgical housestaff coverage. The results indicated that 30 per cent use physician extenders to help cover the ICU during daytime hours and 11 per cent used them during nighttime hours. In addition, 24 per cent used a "night-float" system in an attempt to maintain continuous care, yet still adhere to the mandated guidelines. In conclusion, our survey found multiple strategies, including the use of physician extenders, a "night-float" system, and the use of nongeneral surgical residents in an attempt to provide continuous coverage for surgical ICU patients. The overall outcome of these new strategies still needs to be assessed before any beneficial results can be demonstrated.

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this new approach, EM developed a management structure and principles that led to the creation of specific Focus Areas. These organizations were designed to focus the scientific and technical talent throughout DOE and the national scientific community on the major environmental restoration and waste management problems facing DOE. The Focus Area approach provides the framework for intersite cooperation and leveraging of resources on common problems. After the original establishment of five major Focus Areas within the Office of Technology Development (EM-50, now called the Office of Science and Technology), the Nuclear Materials Stabilization Task Group (EM-66) followed the structure already in place in EM-50 and chartered the Plutonium Focus Area (PFA). The following information outlines the scope and mission of the EM, EM-60, and EM-66 organizations as related to the PFA organizational structure.

    The inability to regulate alcohol consumption has been attributed to an imbalance between stimulus-driven behavioral biases, or action tendencies, and the ability to exert goal-directed control, or working memory capacity (WMC). Previous research assessing the interaction between these variables has not considered the effect of whether individuals' current goals or task demands require goal-directed control. Our aim was to examine the potential interaction of appetitive action tendencies and the ability to exert control over these action tendencies as a function of whether task demands require applying control for successful task completion. Two groups of social drinkers (n = 40 per group) who differed in their ability to regulate their alcohol consumption completed a novel variant of the Approach-Avoidance Task (AAT), which separately assessed approach and avoid trials. The approach and avoidance responses differentially require goal-directed control, depending on whether the task-relevant response is incongruent with the stimulus-driven action tendency. Results indicated that (a) group differences in AAT indices were only observed on trials that required an avoidance movement, which are trials where the task-relevant response would be incongruent with an approach action tendency, and (b) the extent of the group differences for these avoidance trials was moderated by individual differences in WMC, such that problem drinkers with lower WMC showed greater behavioral bias toward alcohol than those with higher WMC. These findings suggest that difficulties in regulating alcohol consumption arise from a complex interaction of action-tendencies, WMC, and current goals or task demands.

    Diabetes mellitus can lead to diabetic polyneuropathy (DPN) and cognitive deficits that manifest as peripheral and central neuropathy, respectively. In this study we investigated the relationship between visuospatial working memory (VSWM) capacity and DPN severity, and attempted to improve VSWM in DPN patients via the use of transcranial direct current stimulation (tDCS). Sixteen DPN patients and 16 age- and education-matched healthy control subjects received Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) and Montreal Cognitive Assessment (MOCA) for baseline cognitive assessment. A forward- and backward-recall computerized Corsi block tapping task (CBT), both with and without a concurrent motor interference task was used to measure VSWM capacity. Each DPN patient underwent a pre-treatment CBT, followed by tDCS or sham treatment, then a post-treatment CBT on two separate days. We found that although patients with severe DPN (Dyck's grade 2a or 2b) showed comparable general intelligence scores on WAIS-IV as their age- and education-matched healthy counterparts, they nonetheless showed mild cognitive impairment (MCI) on MOCA and working memory deficit on digit-span test of WAIS-IV. Furthermore, patients' peripheral nerve conduction velocity (NCV) was positively correlated with their VSWM span in the most difficult CBT condition that involved backward-recall with motor interference such that patients with worse NCV also had lower VSWM span. Most importantly, anodal tDCS over the right DLPFC was able to improve low-performing patients' VSWM span to be on par with the high-performers, thereby eliminating the correlation between NCV and VSWM. In summary, these findings suggest that (1) MCI and severe peripheral neuropathy can coexist with unequal severity in diabetic patients, (2) the positive correlation of VSWM and NCV suggests a link between peripheral and central neuropathies, and (3) anodal tDCS over the right DLPFC can improve DPN patients' VSWM

    This contribution, which serves as the lead article for the Research Topic entitled “From Meaning of Working to Meaningful Lives: The Challenges of Expanding Decent Work,” explores current challenges in the development and operationalization of decent work. Based on an initiative from the International Labor Organization [ILO] (1999) decent work represents an aspirational statement about the quality of work that should be available to all people who seek to work around the globe. Within recent years, several critiques have been raised about decent work from various disciplines, highlighting concerns about a retreat from the social justice ethos that had initially defined the concept. In addition, other scholars have observed that decent work has not included a focus on the role of meaning and purpose at work. To address these concerns, we propose that a psychological perspective can help to revitalize the decent work agenda by infusing a more specific focus on individual experiences and by reconnecting decent work to its social justice origins. As an illustration of the advantages of a psychological perspective, we explore the rise of precarious work and also connect the decent work agenda to the Psychology-of-Working Framework and Theory (Blustein, 2006; Duffy et al., 2016).

    1996-12-31

    The focusing of electromagnetic waves inside a slab has been examined together with two special cases in which the slab is reduced to a single interface or a single medium. To that end the exact solutions for the fields inside a layered medium have been used, given in terms of the outside current source in order to obtain the solutions for the focused electric field inside a slab. Both exact and asymptotic solutions of the problem have been considered, and the validity of the latter has been discussed. The author has developed a numerical algorithm for evaluation of the diffraction integral with special emphasis on reducing the computing time. The numerical techniques in the paper can be readily applied to evaluate similar diffraction integrals occurring e.g. in microstrip antennas. 46 refs.

    Research on the work-family interface began in the 1960s and has grown exponentially ever since. This vast amount of research, however, has had relatively little impact on workplace practice, and work-family conflict is at an all-time high. We review the work-family research to date and propose that a shift of attention is required, away from the individual experience of work and family and toward understanding how identity and status are defined at work. Several factors enshrine cherished identities around current workplace norms. The work devotion schema demands that those who are truly committed to their work will make it the central or sole focus of their lives, without family demands to distract them. Importantly, the work devotion schema underwrites valued class and gender identities: Work devotion is a key way of enacting elite class status and functions as the measure of a man--the longer the work hours and higher the demand for his attention, the better. Advocating change in the way work is done and life is lived meets resistance because it places these cherished identities at risk. Resistance to these identity threats keeps current workplace norms in place. This is why even the business case-which shows that current practices are not economically efficient-fails to persuade organizations to enact change. What is needed now is sustained attention to the implicit psychological infrastructure that cements the mismatch between today's workplace and today's workforce.

    The US Department of Enregy (DOE) Subsurface Contaminants Focus Area is developing technologies to address environmental problems associated with hazardous and radioactive contaminants in soil and groundwater that exist throughout the DOE complex, including radionuclides, heavy metals; and dense non-aqueous phase liquids (DNAPLs). More than 5,700 known DOE groundwater plumes have contaminated over 600 billion gallons of water and 200 million cubic meters of soil. Migration of these plumes threatens local and regional water sources, and in some cases has already adversely impacted off-site rsources. In addition, the Subsurface Contaminants Focus Area is responsible for supplying technologies for the remediation of numerous landfills at DOE facilities. These landfills are estimated to contain over 3 million cubic meters of radioactive and hazardous buried Technology developed within this specialty area will provide efective methods to contain contaminant plumes and new or alternative technologies for development of in situ technologies to minimize waste disposal costs and potential worker exposure by treating plumes in place. While addressing contaminant plumes emanating from DOE landfills, the Subsurface Contaminants Focus Area is also working to develop new or alternative technologies for the in situ stabilization, and nonintrusive characterization of these disposal sites.

    Full Text Available Cognitive overload or underload results in a decrease in human performance which may result in fatal incidents while driving. We envision that driver assistive systems which adapt their functionality to the driver’s cognitive state could be a promising approach to reduce road accidents due to human errors. This research attempts to predict variations of cognitive working memory load levels in a natural driving scenario with multiple parallel tasks and to reveal predictive brain areas. We used a modified version of the n-back task to induce five different working memory load levels (from 0-back up to 4-back forcing the participants to continuously update, memorize, and recall the previous ‘n’ speed sequences and adjust their speed accordingly while they drove for approximately 60 min on a highway with concurrent traffic in a virtual reality driving simulator. We measured brain activation using multichannel whole head, high density functional near-infrared spectroscopy (fNIRS and predicted working memory load level from the fNIRS data by combining multivariate lasso regression and cross-validation. This allowed us to predict variations in working memory load in a continuous time-resolved manner with mean Pearson correlations between induced and predicted working memory load over 15 participants of 0.61 [standard error (SE 0.04] and a maximum of 0.8. Restricting the analysis to prefrontal sensors placed over the forehead reduced the mean correlation to 0.38 (SE 0.04, indicating additional information gained through whole head coverage. Moreover, working memory load predictions derived from peripheral heart rate parameters achieved much lower correlations (mean 0.21, SE 0.1. Importantly, whole head fNIRS sampling revealed increasing brain activation in bilateral inferior frontal and bilateral temporo-occipital brain areas with increasing working memory load levels suggesting that these areas are specifically involved in workload

    In paper the simple model for the definition of interrelation between integral characteristics of Hall thrusters with an anode layer is offered. Concrete calculations were made for one of most often used Hall thrusters - TAL-WSF/D-55. While analysing the received theoretical dependences an attempt of comparison with results of an experimental research of thruster TAL-WSF/D-55 was made. With this purpose experimental dependence of specific impulse of Hall thruster TAL-WSF/D-55 on working voltage in range from 150 up to 350 V resulted in was used. It appeared, that these data contain some serious mistake and there is no reference to original works in this paper. In present report this mistake is corrected using original works. It is shown, that the offered simple model gives results close to a reality both qualitatively and quantitatively.

  9. Theoretical Study of a Spherical Plasma Focus

    Science.gov (United States)

    Ay, Yasar

    A theoretical model is developed for two concentric electrodes spherical plasma focus device in order to investigate the plasma sheath dynamics, radiative emission, and the ion properties. The work focuses on the model development of the plasma sheath dynamics and its validation, followed by studying of the radiation effects and the beam-ion properties in such unique geometry as a pulsed source for neutrons, soft and hard x-rays, and electron and ion beams. Chapter 1 is an introduction on fusion systems including plasma focus. Chapter 2 is an extensive literature survey on plasma focus modeling and experiments including the various radiations and their mechanism. Chapter 3 details modeling and validation of the plasma sheath dynamics model with comparison between hydrogen, deuterium, tritium and deuterium-tritium mixture for the production of pulsed neutrons. Chapter 4 is a study of the radiative phase, in which neutron yield is investigated, as well as the predicted beam-ion properties. Chapter 5 summarizes and discusses the results. Chapter 6 provides concluding remarks and proposed future works. The phases of the developed model are the rundown phase I, rundown phase II, the reflected phase and a radiative phase. The rundown phase I starts immediately after the completion of the gas breakdown and ends when the current sheath reaches the equator point of the spherical shape. Then immediately followed by rundown phase II to start and it ends when the shock front hits the axis, which is the beginning of the reflected shock phase. Reflected shock front moves towards the incoming current sheath and meets it which is both the end of the reflected shock phase and the beginning of the radiative phase. After the reflected shock front and the current sheath meet, the current sheath continues to move radially inward by compressing the produced plasma column until it reaches the axis. Since the discharge current contains important information about the plasma dynamic

    elements of the puzzle, and those which combine them. Scales, assumptions and the conditions used in order to describe a particular single process of interest must be consistent with the conditions in clouds. The papers in this focus issue of New Journal of Physics collectively demonstrate (i) the variation in scientific approaches towards investigating cloud processes, (ii) the various stages of shaping elements of the puzzle, and (iii) some attempts to put the pieces together. These papers present just a small subset of loosely arranged elements in an initial stage of puzzle creation. Addressed by this issue is one of the important problems in our understanding of cloud processes—the interaction between cloud particles and turbulence. There is currently a gap between the cloud physics community and scientists working in wind tunnels, on turbulence theory and particle interactions. This collection is intended to narrow this gap by bringing together work by theoreticians, modelers, laboratory experimentalists and those who measure and observe actual processes in clouds. It forms a collage of contributions showing various approaches to cloud processes including: • theoretical works with possible applications to clouds (Bistagnino and Boffetta, Gustavsson et al), • an attempt to construct a phenomenological description of clouds and rain (Lovejoy and Schertzer), • simplified models designed to parameterize turbulence micro- and macro-effects (Celani et al, Derevyanko et al), • focused theoretical research aimed at particular cloud processes (Ayala et al, parts I and II, Wang et al), • laboratory and modeling studies of complex cloud processes (Malinowski et al). This collage is far from being complete but, hopefully, should give the reader a representative impression of the current state of knowledge in the field. We hope it will be useful to all scientists whose work is inspired by cloud processes. Focus on Cloud Physics Contents The equivalent size of cloud

    In spite of the intense research activities on Plasma Focus devices, the physics of the initial breakdown and surface discharge phase has not been realized completely. In this paper we have analyzed the surface discharge and initial breakdown phase in Filippov-type Plasma Focus Facility "Dena" (90 kJ, 25 kV) on the base of the current and current derivative measured signals by using Argon, Neon and Krypton as working gases at different discharge voltages and gas pressures, and the effects of working conditions (atomic weight, discharge voltage and gas pressure) on the breakdown and surface discharge phase have expressed. Also, on the base of these results, we have investigated about the relation of this phase with final pinch phase.

    Plasmonics is an emerging field in optics dealing with the so-called surface plasmons whose extraordinary properties are being both analyzed from a fundamental point of view and exploited for numerous technological applications. Surface plasmons associated with surface electron density oscillations decorating metal-dielectric interfaces were discovered by Rufus Ritchie in the 1950s. Since the seventies, the subwavelength confinement of electromagnetic fields as well as their enhancement inherent to the surface plasmon excitation has been widely used for spectroscopic purposes. Recent advances in nano-fabrication, characterization and modelling techniques have allowed unique properties of these surface electromagnetic modes to be explored with respect to subwavelength field localization and waveguiding, opening the path to truly nanoscale plasmonic optical devices. This area of investigation also has interesting links with research on photonic band gap materials and the field of optical metamaterials. Nowadays, plasmonics can be seen as a mature interdisciplinary area of research in which scientists coming from different backgrounds (chemistry, physics, optics and engineering) strive to discover and exploit new and exciting phenomena associated with surface plasmons. The already made and forthcoming discoveries will have impacts in many fields of science and technology, including not only photonics and materials science but also computation, biology and medicine, among others. This focus issue of New Journal of Physics is intended to cover all the aforementioned capabilities of surface plasmons by presenting a current overview of state-of-the-art advances achieved by the leading groups in this field of research. The below list of articles represents the first contributions to the collection and further additions will appear soon.

    Drug costs have risen rapidly in the last decade, driving third-party payers to adopt performance-based agreements that provide either a discount before payment or an ex post reimbursement on the basis of treatments' effectiveness and/or safety issues. This article analyses the strategies currently approved in Italy and proposes a novel model called "success fee" to improve payment-by-result schemes and to guarantee patients rapid access to novel therapies. A review of the existing risk-sharing schemes in Italy has been performed, and data provided by the Italian National report (2012) on drug use have been analyzed to assess the impact on drug expenditure deriving from the application of "traditional" performance-based strategies since their introduction in 2006. Such schemes have poorly contributed to the fulfillment of the purpose in Italy, producing a trifling refund, compared with relevant drugs costs for the National Health System : €121 million out of a total of €3696 million paid. The novel risk-sharing agreement called "success fee" has been adopted for a new high-cost therapy approved for idiopathic pulmonary fibrosis, pirfenidone, and consists of an ex post payment made by the National Health System to the manufacturer for those patients who received a real benefit from treatment. "Success fee" represents an effective strategy to promote value-based pricing, making available to patients a rapid access to innovative and expensive therapies, with an affordable impact on drug expenditure and, simultaneously, ensuring third-party payers to share with manufacturers the risk deriving from uncertain safety and effectiveness.

  19. Current ornithology

    CERN Document Server

    1983-01-01

    The appearance of the first volume of a projected series is the occasion for comment on scope, aims, and genesis of the work. The scope of Current Ornithology is all of the biology of birds. Ornithology, as a whole-organism science, is concerned with birds at every level of bi­ ological organization, from the molecular to the community, at least from the Jurassic to the present time, and over every scholarly discipline in which bird biology is done; to say this is merely to expand a dic­ tionary definition of "ornithology. " The aim of the work, to be realized over several volumes, is to present reviews or position statements con­ cerning the active fields of ornithological research. The reviews will be relatively short, and often will be done from the viewpoint of a readily­ identified group or school. Such a work could have come into being at any time within the past fifty years, but that Current Ornithology appears now is a result of events that are only seven to eight years old.

  1. Opposing Shear-Induced Forces Dominate Inertial Focusing in Curved Channels and High Reynolds Numbers

    CERN Document Server

    Keinan, Eliezer; Nahmias, Yaakov

    2015-01-01

    Inertial focusing is the migration of particles in fluid toward equilibrium, where current theory predicts that shear-induced and wall-induced lift forces are balanced. First reported in 1961, this Segre-Silberberg effect is particularly useful for microfluidic isolation of cells and particles. Interestingly, recent work demonstrated particle focusing at high Reynolds numbers that cannot be explained by current theory. In this work, we show that non-monotonous velocity profiles, such as those developed in curved channels, create peripheral velocity maxima around which opposing shear-induced forces dominate over wall effects. Similarly, entry effects amplified in high Reynolds flow produce an equivalent trapping mechanism in short, straight channels. This new focusing mechanism in the developing flow regime enables a 10-fold miniaturization of inertial focusing devices, while our model corrects long-standing misconceptions about the nature of mechanical forces governing inertial focusing in curved channels.

    2013-09-15

    Nondestructive testing (NDT) plays a critical role in maintaining quality and guaranteeing the safety of industries by predicting or assessing the performance and service life of a structure throughout its lifecycle, from manufacturing to operation and maintenance. The ability to assess the integrity of a material, component or structure without affecting its useful life provides perfect balance between quality control and cost-effectiveness. NDT is also used for equipment life assessment or condition assessment to estimate the operational life of plant components, such as processing lines, pipes, tanks and pressure vessels, etc. Based on this information, strategic plans can be developed for extending the useful life of these components. There are more than 60 techniques for performing NDT, with newer techniques being developed at a rapid pace. However, based on the item being inspected, these techniques can be broadly classified into two categories: surface inspection and volumetric inspection. Techniques like dye penetrant testing, magnetic testing, and eddy current testing are classified under surface inspection, with radiography, ultrasonic testing, and acoustic emission classified under volumetric inspection. The traditional or conventional NDT techniques, such as magnetic particle inspection, penetrant testing, radiography and ultrasonic testing, have been around for nearly a century. However, these and the other technologies have evolved significantly since their inception, with newer advanced techniques developed over the past two decades. Amongst the most notable advancements in technology include phased array ultrasonic testing and digital radiography. In an industry where adoption of new technology is a key challenge, the success phased array and digital radiography have achieved as mainstream inspection techniques is noteworthy. (author)

    2014-12-15

    The main characteristics of focused electron beam induced deposition (FEBID) and focused ion beam induced deposition (FIBID) are presented. FEBID and FIBID are two nanopatterning techniques that allow the fabrication of submicron patterns with nanometer resolution on selected locations of any kind of substrate, even on highly structured supports. The process consists of mask less serial deposition and can be applied to a wide variety of materials, depending strictly on the precursor material source used. The basic mechanism of FEBID and FIBID is the adsorption of volatile precursor molecules onto the sample surface and decomposition of the molecules induced by the energetic electron and ion focused beams. The essential similarities of the two techniques are presented and especial emphasis is dedicated to highlighting their main differences, such as aspects related to resolution, deposition rate, deposits purity, substrate integrity, etc. In both cases, the factors interplay and complex mechanisms are still understood in a qualitative basis, so much work can still be done in terms of modeling and simulating the processes involved in FEBID and FIBID. Current work on FEBID and FIBID is presented through examples of achievements, interesting results and novel approaches.

    A directly heated thermionic electron beam source was constructed. A tungsten wire of length 140 mm with diameter 0.9 mm was used as a cathode. An emission current of 5000 mA was achieved at an input heating power of 600 W. Cathode to anode distance of 6 mm with acceleration voltage of 10 kV was used. A uniform external magnetic field of 50 G was employed to obtain a well-focused electron beam at a deflection of 180°, with cathode to work site distance of 130 mm. Dimensions of the beam (1.25×120 mm) recorded at the work site were found to be in good agreement with the designed length of cathode. The deformation of the cathode was overcome by introducing a spring action mechanism, which gives uniform emission current density throughout the emission surface. We have achieved the saturation limit of the designed source resulting in smooth and swift operation of the gun for many hours (10-15 h continuously). The design of gun is so simple that it can accommodate longer cathodes for obtaining higher emission values. This gun has made it possible to coat large substrate surfaces at much faster evaporation rate at lower cost. It can also be useful in large-scale vacuum metallurgy plants for melting, welding and heat treatment.

    Lowder, Matthew W; Gordon, Peter C

    2015-12-01

    Previous eye-tracking work has yielded inconsistent evidence regarding whether readers spend more or less time encoding focused information compared with information that is not focused. We report the results of an eye-tracking experiment that used syntactic structure to manipulate whether a target word was linguistically defocused, neutral, or focused, while controlling for possible oculomotor differences across conditions. As the structure of the sentence made the target word increasingly more focused, reading times systematically increased. We propose that the longer reading times for linguistically focused words reflect deeper encoding, which explains previous findings showing that readers have better subsequent memory for focused versus defocused information.

  1. Focused ultrasound in ophthalmology

    Full Text Available Ronald H Silverman1,2 1Department of Ophthalmology, Columbia University Medical Center, 2F.L. Lizzi Center for Biomedical Engineering, Riverside Research, New York, NY, USA Abstract: The use of focused ultrasound to obtain diagnostically significant information about the eye goes back to the 1950s. This review describes the historical and technological development of ophthalmic ultrasound and its clinical application and impact. Ultrasound, like light, can be focused, which is crucial for formation of high-resolution, diagnostically useful images. Focused, single-element, mechanically scanned transducers are most common in ophthalmology. Specially designed transducers have been used to generate focused, high-intensity ultrasound that through thermal effects has been used to treat glaucoma (via cilio-destruction, tumors, and other pathologies. Linear and annular transducer arrays offer synthetic focusing in which precise timing of the excitation of independently addressable array elements allows formation of a converging wavefront to create a focus at one or more programmable depths. Most recently, linear array-based plane-wave ultrasound, in which the array emits an unfocused wavefront and focusing is performed solely on received data, has been demonstrated for imaging ocular anatomy and blood flow. While the history of ophthalmic ultrasound extends back over half-a-century, new and powerful technologic advances continue to be made, offering the prospect of novel diagnostic capabilities.

  5. Planar-Focusing Cathodes

    CERN Document Server

    Lewellen, J W

    2005-01-01

    Conventional pi-mode rf photoinjectors typically use magnetic solenoids for emittance compensation. This provides independent focusing strength, but can complicate rf power feed placement, introduce asymmetries (due to coil crossovers), and greatly increase the cost of the photoinjector. Cathode-region focusing can also provide for a form of emittance compensation. Typically this method strongly couples focusing strength to the field gradient on the cathode, however, and also requires altering the longitudinal position of the cathode to change the focusing. We propose a new method for achieving cathode-region variable-strength focusing for emittance compensation. The new method reduces the coupling to the gradient on the cathode, and does not require a change in the longitudinal position of the cathode. Expected performance for an S-band system is similar to conventional solenoid-based designs. This paper presents the results of rf cavity and beam dynamics simulations of the new design.

    Full Text Available The definition of STEM (Science, Technology, Engineering, and Mathematics reforms remains unclear. STEM is not like a scientific term where scientists choose to replace a series of complex observations with a new word. Even with more and more money being spent to support STEM reforms in all K-12 classrooms, we continue to not have accurate ideas of what STEM efforts are and/or what they could/should accomplish. Some STEM changes have been proposed and considered for use in several statewide efforts across the United States. But, to what end? Will major funding improve the personal “doing” of science for all students and at all grade levels?

  11. Visual neglect following stroke: current concepts and future focus.

    2011-01-01

    Visual neglect is a common, yet frequently overlooked, neurological disorder following stroke characterized by a deficit in attention and appreciation of stimuli on the contralesional side of the body. It has a profound functional impact on affected individuals. A assessment and management of this condition are hindered, however, by the lack of professional awareness and clinical guidelines. Recent evidence suggests that the underlying deficit in visual attention is due to a disrupted internalized representation of the outer world rather than a disorder of sensory inputs. Dysfunction of the cortical domains and white-matter tracts, as well as inter-hemispheric imbalance, have been implicated in the various manifestations of visual neglect. Optimal diagnosis requires careful history-taking from the patient, family, and friends, in addition to clinical assessment with the line bisection test, the star cancellation test, and the Catherine Bergego Scale. Early recognition and prompt rehabilitation employing a multidisciplinary approach is desirable. Although no treatment has been definitively shown to be of benefit, those with promise include prism adaptation, visual scanning therapy, and virtual reality-based techniques. Further high quality research to seek optimum short- and long-term rehabilitative strategies for visual neglect is required.

    Practical application of psychodynamic therapy technique requires that the therapist focus the treatment. The authors review the current evidence about focus in psychotherapy, which suggests that it has a beneficial impact on outcome and patient satisfaction. The core psychodynamic problem is proposed as a valuable conceptual model for providing focus for patient, psychotherapist, and supervisor. The authors narrate a case history from the perspective of both the psychotherapist and the supervisor to demonstrate the opportunities and challenges in using this concept. Finally, the authors suggest that a focus on focus is desirable in residency psychotherapy training programs, and they make suggestions for educational methods that enhance resident training in this area.

    Preliminary results of a 600 J (3.7 μF, 18 kV) Mather type plasma focus device operated at low pressure will be presented. The discharge is formed between a solid anode with length of 6 cm and six symmetrically and coaxially arranged cathode rods of same lengths. The cathode base is profiled in a knife-edge design and a set of coaxial plasma gun are attached to it in order to initiate the breakdown and enhance the current sheath formation. The experiments have been performed in argon gas under a low pressure condition of several microbars. The discharge current and the voltage across the electrodes during the discharge are measured with high voltage probe and current coil. The current and voltage characteristics are used to determine the possible range of operating pressure that gives good focusing action. At a narrow pressure regime of 9.0±0.5 μbar, focusing action is observed with good reproducibility. Preliminary result of ion beam energy is presented. More work will be carried out to investigate the radiation output.

    Full Text Available This paper investigates the focusing properties of linear magnetic undulators, i.e., devices characterized by weak defocusing properties in the horizontal (wiggling plane and strongly focusing in the vertical plane. The problem of identifying the conditions that ensure the existence of the electron beam eigenstates in the undulator lattice for a given working point of electron beam energy E_{b} and resonant wavelength λ_{r} is studied. For any given undulator lattice, a bandlike structure is identified defining regions in the (E_{b},λ_{r} plane where no periodic matching condition can be found, i.e., it is not possible to transport the electron beam so that optical functions are periodic at lattice boundaries. Some specific cases are discussed for the SPARC FEL undulator.

    The quantization of the scalar and electromagnetic fields in the presence of a parabolic mirror is further developed in the context of a geometric optics approximation. We calculate the mean squared scalar and electric fields near the focal line of a parabolic cylindrical mirror. These quantities are found to grow as inverse powers of the distance from the focus. We give a combination of analytic and numerical results for the mean squared fields. In particular, we find that the mean squared electric field can be either negative or positive, depending upon the choice of parameters. The case of a negative mean squared electric field corresponds to a repulsive Van der Waals force on an atom near the focus, and to a region of negative energy density. Similarly, a positive value corresponds to an attractive force and a possibility of atom trapping in the vicinity of the focus.

    All brain normal or pathological activities occur in one of the states of vigilance: wake, slow-wave sleep, or REM sleep. Neocortical seizures preferentially occur during slow-wave sleep. We provide a description of neuronal behavior and mechanisms mediating such a behavior within neocortex taking place in natural states of vigilance as well as during seizures pointing to similarities and differences exhibited during sleep and seizures. A concept of epileptic focus is described using a model of cortical undercut, because in that model, the borders of the focus are well defined. In this model, as in other models of acquired epilepsy, the main factor altering excitability is deafferentation, which upregulates neuronal excitability that promotes generation of seizures. Periods of disfacilitation recorded during slow-wave sleep further upregulate neuronal excitability. It appears that the state of neurons and neuronal network in the epileptic focus produced by deafferentation are such that seizures cannot be generated there. Instead, seizures always start around the perimeter of the undercut cortex. Therefore, we define these areas as the seizure focus. In this zone, neuronal connectivity and excitability are moderately enhanced, lowering the threshold for seizure generation. © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Angela Mariani,1 Antonella Vastola2 1Department of Economic and Legal Studies, University Parthenope, Naples, 2School of Agricultural, Forestry, Food and Environmental Sciences, University of Basilicata, Potenza, Italy Abstract: The winegrowing sector worldwide is strongly committed to improving environmental and social sustainability. The aim of this work, based on a literature review, is to highlight current sustainability perspectives and the related main issues. There is a broad consensus that the challenge to achieve a greater spread of sustainable practices is to enhance environmental and social sustainability while maintaining economic viability. From the producers' point of view, the priority is to bridge the still substantial knowledge gaps in terms of perceived environmental benefits, economic benefits, and costs. Thus, an increased research effort focusing on the costs and benefits of different winegrowing practices and technical assistance with implementation might support their diffusion. Moreover, targeted marketing strategies are needed to: enhance consumers' involvement and their attitude toward sustainable wine; improve understanding and use of sustainable labels and claims; and raise awareness of some environmental credentials of wine packaging, mainly with reference to lightweight glass bottles. Keywords: winegrower, sustainability, wine, consumer, marketing strategies

Firstly, protons were accelerated to an energy of 26 GeV in the PS and ejected onto a metal target. From the spray of emerging particles, a magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet.For a million protons hitting the target, just one antiproton was captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 -, three hundred thousand million - antiprotons.

    2009-01-01

    Full Text Available Organic materials are usually thought of as electrical insulators. Progress in chemical synthesis, however, has brought us a rich variety of conducting organic materials, which can be classified into conducting polymers and molecular crystals. Researchers can realize highly conducting molecular crystals in charge-transfer complexes, where suitable combinations of organic electron donor or acceptor molecules with counter ions or other organic molecules provide charge carriers. By means of a kind of chemical doping, the charge-transfer complexes exhibit high electrical conductivity and, thanks to their highly crystalline nature, even superconductivity has been observed. This focus issue of Science and Technology of Advanced Materials is devoted to the research into such 'organic conductors'The first organic metal was (TTF(TCNQ, which was found in 1973 to have high conductivity at room temperature and a metal–insulator transition at low temperatures. The first organic superconductor was (TMTSF2PF6, whose superconductivity under high pressures was reported by J´erome in 1980. After these findings, the research on organic conductors exploded. Hundreds of organic conductors have been reported, among which more than one hundred exhibit superconductivity. Recently, a single-component organic conductor has been found with metallic conductivity down to low temperatures.In these organic conductors, in spite of their simple electronic structures, much new physics has arisen from the low dimensionality. Examples are charge and spin density waves, characteristic metal–insulator transitions, charge order, unconventional superconductivity, superconductor–insulator transitions, and zero-gap conductors with Dirac cones. The discovery of this new physics is undoubtedly derived from the development of many intriguing novel organic conductors. High quality single crystals are indispensable to the precise measurement of electronic states.This focus issue

    During the half-century history of x-ray astronomy, focusing x-ray telescopes, through increased effective area and finer angular resolution, have improved sensitivity by 8 orders of magnitude. Here, we review previous and current x-ray-telescope missions. Next, we describe the planned next-generation x-ray-astronomy facility, the International X-ray Observatory (IXO). We conclude with an overview of a concept for the next next-generation facility, Generation X. Its scientific objectives will require very large areas (about 10,000 sq m) of highly-nested, lightweight grazing-incidence mirrors, with exceptional (about 0.1-arcsec) resolution. Achieving this angular resolution with lightweight mirrors will likely require on-orbit adjustment of alignment and figure.

    Alliance-focused training (AFT) aims to increase therapists' ability to recognize, tolerate, and negotiate alliance ruptures by increasing the therapeutic skills of self-awareness, affect regulation, and interpersonal sensitivity. In AFT, therapists are encouraged to draw on these skills when metacommunicating about ruptures with patients. In this article, we present the 3 main supervisory tasks of AFT: videotape analysis of rupture moments, awareness-oriented role-plays, and mindfulness training. We describe the theoretical and empirical support for each supervisory task, provide examples based on actual supervision sessions, and present feedback about the usefulness of the techniques from trainees in our program. We also note some of the challenges involved in conducting AFT and the importance of maintaining a strong supervisory alliance when using this training approach.

  12. Focusing on customer service.

    Science.gov (United States)

    1996-01-01

    This booklet is devoted to a consideration of how good customer service in family planning programs can generate demand for products and services, bring customers back, and reduce costs. Customer service is defined as increasing client satisfaction through continuous concern for client preferences, staff accountability to clients, and respect for the rights of clients. Issues discussed include the introduction of a customer service approach and gaining staff commitment. The experience of PROSALUD in Bolivia in recruiting appropriate staff, supervising staff, soliciting client feedback, and marketing services is offered as an example of a successful customer service approach. The key customer service functions are described as 1) establishing a welcoming atmosphere, 2) streamlining client flow, 3) personalizing client services, and 4) organizing and providing clear information to clients. The role of the manager in developing procedures is explored, and the COPE (Client-Oriented Provider-Efficient) process is presented as a good way to begin to make improvements. Techniques in staff training in customer service include brainstorming, role playing, using case studies (examples of which are provided), and engaging in practice sessions. Training also leads to the development of effective customer service attitudes, and the differences between these and organizational/staff-focused attitudes are illustrated in a chart. The use of communication skills (asking open-ended questions, helping clients express their concerns, engaging in active listening, and handling difficult situations) is considered. Good recovery skills are important when things go wrong. Gathering and using client feedback is the next topic considered. This involves identifying, recording, and discussing customer service issues as well as taking action on these issues and evaluating the results. The booklet ends by providing a sample of customer service indicators, considering the maintenance of a

    2013-01-01

    Professional development has evolved from individually focused sabbaticals and professional leaves to institutionally focused programs with an interest in developing faculty members' ability to teach in various environments as well as to succeed in the many endeavors they undertake. We address various issues related to professional development in the medical school arena. Professional development in medical school takes place in a context where faculty are stretched to engage in research and service not only for their own sake but also to financially support their institutions. This obligates professional developers to acknowledge and address the environments in which teaching faculty work, and to use approaches to professional development that honor the time and efforts of teaching faculty. These approaches may be brief interventions that make use of principles of education, and may include online offerings. Professional development will be most effective when professional developers acknowledge that most faculty members aspire to excellence in teaching, but they do so in an environment that pushes them to address competing concerns. Offering professional development opportunities that fit within the workplace environment, take little time, and build upon faculty's existing knowledge will assist in enhancing faculty success.

    Plasma foci of compact sizes and operating with low energies (from tens of joules to few hundred joules) have found application in recent years and have attracted plasma-physics scientists and engineers for research in this direction. We are presenting a low energy and miniature plasma focus which operates from a capacitor bank of 8.4 muF capacity, charged at 4.2-4.3 kV and delivering approximately 52 kA peak current at approximately 60 nH calculated circuit inductance. The total circuit inductance includes the plasma focus inductance. The reported plasma focus operates at the lowest voltage among all reported plasma foci so far. Moreover the cost of capacitor bank used for plasma focus is nearly 20 U.S. dollars making it very cheap. At low voltage operation of plasma focus, the initial breakdown mechanism becomes important for operation of plasma focus. The quartz glass tube is used as insulator and breakdown initiation is done on its surface. The total energy of the plasma focus is approximately 75 J. The plasma focus system is made compact and the switching of capacitor bank energy is done by manual operating switch. The focus is operated with hydrogen and deuterium filled at 1-2 mbar.

    Full Text Available The role of PTEN as a tumour suppressor has been for a long time attributed to its lipid phosphatase activity against PI(3,4,5P3, the phospholipid product of the class I PI3Ks. Besides its traditional role as a lipid phosphatase at the plasma membrane, a wealth of data has shown that PTEN can function independently of its phosphatase activity and that PTEN also exists and plays a role in the nucleus, in cytoplasmic organelles and extracellularly. Accumulating evidence has shed light on diverse physiological functions of PTEN which are accompanied by a complex regulation of its expression and activity. PTEN levels and function are regulated transcriptionally, post-transcriptionally and post-translationally. PTEN is also sensitive to regulation by its interacting proteins and its localization. Herein, we summarize the current knowledge on mechanisms that regulate the expression and enzymatic activity of PTEN and its role in human diseases.

    The NSLS X28C white-light beamline is being outfitted with a focusing mirror in order to increase, as well as control, the x-ray intensity at the sample position. The new mirror is a 50 mm × 100 mm × 1100 mm single crystal silicon cylindrical 43.1mm radius substrate bendable to a toroid from infinite to 1200 m radius. The unique feature of this mirror system is the dual use of Indalloy 51 as both a mechanism for heat transfer and a buoyant support to negate the effects of gravity. The benefit of the liquid metal support is the ability to correct for minor slope errors that take the form of a parabola. A bobber mechanism is employed to displace the fluid under the mirror +/- 1.5 mm. This allows RMS slope error correction on the order of 2 urad. The unique mounting of the mirror ensures the contributions to slope error from errant mechanical stresses due to machining tolerances are virtually non-existent. After correction, the surface figure error (measured minus ideal) is <= 0.5 urad rms.

  2. Attentional Focusing Instructions and Force Production

    2011-01-01

    Full Text Available Research progress assessing the role of attentional focusing instructions on skill acquisition and performance has lead researchers to apply this approach to force production tasks. Initial converging evidence indicates that force production tasks are sensitive to verbal instruction; externally focused instructions (onto movement outcomes, or onto the object force is being exerted against are shown to be more beneficial than internally focused instructions (focusing attention onto the movements being executed. These benefits are observed for maximal and accurate force production, as well as the maintenance of force production in prolonged tasks. A range of mechanisms are identified supporting the proposal that an external focus promotes movement efficiency in line with energy and effort conservation. Future research is required to assess how this developing body of work interacts with the broader understanding of psychological and physiological factors implicated in the effective production, maintenance and limitation of maximal or sub-maximal forces.

    The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

    Conversion of laser radiation to mechanical energy is the fundamental process behind many medical laser procedures, particularly those involving tissue destruction and removal. Stress waves can be generated with laser radiation in several ways: creation of a plasma and subsequent launch of a shock wave, thermoelastic expansion of the target tissue, vapor bubble collapse, and ablation recoil. Thermoelastic generation of stress waves generally requires short laser pulse durations and high energy density. Thermoelastic stress waves can be formed when the laser pulse duration is shorter than the acoustic transit time of the material: {tau}{sub c} = d/c{sub s} where d = absorption depth or spot diameter, whichever is smaller, and c{sub s} = sound speed in the material. The stress wave due to thermoelastic expansion travels at the sound speed (approximately 1500 m/s in tissue) and leaves the site of irradiation well before subsequent thermal events can be initiated. These stress waves, often evolving into shock waves, can be used to disrupt tissue. Shock waves are used in ophthalmology to perform intraocular microsurgery and photodisruptive procedures as well as in lithotripsy to fragment stones. We have explored a variety of transducers that can efficiently convert optical to mechanical energy. One such class of transducers allows a shock wave to be focused within a material such that the stress magnitude can be greatly increased compared to conventional geometries. Some transducer tips could be made to operate regardless of the absorption properties of the ambient media. The size and nature of the devices enable easy delivery, potentially minimally-invasive procedures, and precise tissue- targeting while limiting thermal loading. The transducer tips may have applications in lithotripsy, ophthalmology, drug delivery, and cardiology.

  9. EDITORIAL: Focus on Gravitational Lensing

    Gravitational lensing emerged as an observational field following the 1979 discovery of a doubly imaged quasar lensed by a foreground galaxy. In the 1980s and '90s dozens of other multiply imaged systems were observed, as well as time delay measurements, weak and strong lensing by galaxies and galaxy clusters, and the discovery of microlensing in our galaxy. The rapid pace of advances has continued into the new century. Lensing is currently one of best techniques for finding and mapping dark matter over a wide range of scales, and also addresses broader cosmological questions such as understanding the nature of dark energy. This focus issue of New Journal of Physics presents a snapshot of current research in some of the exciting areas of lensing. It provides an occasion to look back at the advances of the last decade and ahead to the potential of the coming years. Just about a decade ago, microlensing was discovered through the magnification of stars in our galaxy by invisible objects with masses between that of Jupiter and a tenth the mass of the Sun. Thus a new component of the mass of our galaxy, dubbed MACHOs, was established (though a diffuse, cold dark matter-like component is still needed to make up most of the galaxy mass). More recently, microlensing led to another exciting discovery—of extra-solar planets with masses ranging from about five times that of Earth to that of Neptune. We can expect many more planets to be discovered through ongoing surveys. Microlensing is the best technique for finding Earth mass planets, though it is not as productive overall as other methods and does not allow for follow up observations. Beyond planet hunting, microlensing has enabled us to observe previously inaccessible systems, ranging from the surfaces of other stars to the accretion disks around the black holes powering distant quasars. Galaxies and galaxy clusters at cosmological distances can produce dramatic lensing effects: multiple images of background galaxies

    Full Text Available Family and community medicine assumes a new epistemological landmark that also provides the use of instruments and tools related to it. This care model permits carrying out a visit where all categories which the health-disease process is expressed are present. Family Medicine intends to combine both visions and, for such, it gifts elements to incorporate disease as an essential part of our patient's approach systematic being the main focus the approach by problems, which is nothing but that which concerns the individual, his family or the physician, or all of them, and at times there will be nuisances while at other times, there will be diseases, and mil in other instances, all of them will co-exist. It is known that the impact of a health problem on an individual affects not only himself, but also his surroundings. In turn, the environment around this individual can act as the origin or perpetuator of the crisis, or else serve to help in solving the conflict. Distinct tools serve the purpose of knowing the context in which health crisis is developed, such as: genogram, individual and family vital cycle. Every time two people communicate, the agreement or disagreement generate possible variables. In the physician-patient relationship, this is no exception. Values, beliefs, feelings, and information of each individual different and physicians not necessarily in agreement in several issues during a visit. The objective is the need to achieve a minimum of agreements so that this visit has therapeutic effectiveness, thus being if/rpm -taw to find a common territory. Relations in general involve power; care, feelings, trust and goals. The objective in this type of relationship must be obviously shared ly both and cannot be any other than that of achieving, the highest level of health to our patient.

    This review examines recent theoretical and empirical developments in the leadership literature, beginning with topics that are currently receiving attention in terms of research, theory, and practice. We begin by examining authentic leadership and its development, followed by work that takes a cognitive science approach. We then examine new-genre leadership theories, complexity leadership, and leadership that is shared, collective, or distributed. We examine the role of relationships through our review of leader member exchange and the emerging work on followership. Finally, we examine work that has been done on substitutes for leadership, servant leadership, spirituality and leadership, cross-cultural leadership, and e-leadership. This structure has the benefit of creating a future focus as well as providing an interesting way to examine the development of the field. Each section ends with an identification of issues to be addressed in the future, in addition to the overall integration of the literature we provide at the end of the article.

Desde os anos 1980, a tentativa da América Latina em reorganizar sua vida pública em conformidade com os preceitos democráticos liberais demonstrou uma desigualdade de forças políticas na negociação desta transição, onde avanços políticos foram acompanhados pelo agravamento das condições de vida das maiorias nacionais. Como o Serviço Social crítico surge - historicamente - no marco de ordenamentos democráticos, a conformação da profissão relaciona-se intrinsecamente com as debilidades deste processo, onde emergem novos desafios para construção da identidade dos assistentes sociais, principalmente no debate do sentido da sua prática, do processo de conhecimento crítico e no redimensionamento de propostas relevantes na defesa de um projeto socialmente necessário no contexto latino-americano atual.This article analyses the particularities of the redemocratization process of Latin American political regimes, in an attempt to contribute to the understanding of phenomenon central to our societies today.

    future involve using overdense plasmas. Electronic processes on sub-atomic spatio-temporal scales are the basis of chemical physics, atomic, molecular, and optical physics, materials science, and even some life science processes. Research in these areas using the new attosecond tools will advance together with the ability to control electrons themselves. Indeed, we expect that developments will advance in a way that is similar to advances that have occurred on the femtosecond time scale, in which much previous experimental and theoretical work on the interaction of coherent light sources has led to the development of means for 'coherent control' of nuclear motion in molecules. This focus issue of New Journal of Physics is centered on experimental and theoretical advances in the development of new methodologies and tools for electron control on the attosecond time scale. Topics such as the efficient generation of harmonics; the generation of attosecond pulses, including those having only a few cycles and those produced from overdense plasmas; the description of various nonlinear, nonperturbative laser-matter interactions, including many-electron effects and few-cycle pulse effects; the analysis of ultrashort propagation effects in atomic and molecular media; and the development of inversion methods for electron tomography, as well as many other topics, are addressed in the current focus issue dedicated to the new field of 'Attosecond Physics'.

  9. Fredholm's equations for subwavelength focusing

    2012-10-01

    Subwavelength focusing (SF) is a very useful tool that can be carried out with the use of left hand materials for optics that involve the range of the microwaves. Many recent works have described a successful alternative procedure using time reversal methods. The advantage is that we do not need devices which require the complicated manufacture of left-hand materials; nevertheless, the theoretical mathematical bases are far from complete because before now we lacked an adequate easy-to-apply frame. In this work we give, for a broad class of discrete systems, a solid support for the theory of electromagnetic SF that can be applied to communications and nanotechnology. The very central procedure is the development of vector-matrix formalism (VMF) based on exploiting both the inhomogeneous and homogeneous Fredholm's integral equations in cases where the last two kinds of integral equations are applied to some selected discrete systems. To this end, we first establish a generalized Newmann series for the Fourier transform of the Green's function in the inhomogeneous Fredholm's equation of the problem. Then we go from an integral operator equation to a vector-matrix algebraic one. In this way we explore the inhomogeneous case and later on also the very interesting one about the homogeneous equation. Thus, on the one hand we can relate in a simple manner the arriving electromagnetic signals with those at their sources and we can use them to perform a SF. On the other hand, we analyze the homogeneous version of the equations, finding resonant solutions that have analogous properties to their counterparts in quantum mechanical scattering, that can be used in a proposed very powerful way in communications. Also we recover quantum mechanical operator relations that are identical for classical electromagnetics. Finally, we prove two theorems that formalize the relation between the theory of Fredholm's integral equations and the VMF we present here.

    The focusing of spin waves in magnetic materials has a number of important advantages for directing energy and thus information. In contrast to earlier works, we theoretically calculate the focusing of short-wavelength spin waves. We show that strong focusing of large wave-vector spin waves naturally occurs about halfway out in the Brillouin zone with no need for a magnetocrystalline anisotropy, dipolar effects, or an external magnetic field. The fact that the wavelength is on the order of the lattice constant leads to a form of lattice-induced anisotropy in the wave propagation. We also explore the tunability that is achieved by the application of both an external field and a uniaxial anisotropy. In this case there is a rotation of the focusing pattern. The rotation angle can be changed by varying the field strength, demonstrating tunability.

    Optimism bias is a crucial feature of risk perception that leads to increased risk-taking behaviour, which is a particularly salient issue among pilots in aviation settings due to the high-stakes nature of flight. The current study sought to address the roles of narcissism and promotion focus on optimism bias in risk perception in aviation context. Participants were 239 male flight cadets from the Civil Aviation Flight University of China who completed the Narcissistic Personality Inventory-13, the Work Regulatory Focus Scale, and an indirect measure of unrealistic optimism in risk perception, which measured risk perception for the individual and the risk assumed by other individuals performing the same task. Higher narcissism increased the likelihood of underestimating personal risks, an effect that was mediated by high promotion focus motivation, such that high narcissism led to high promotion focus motivation. The findings have important implications for improving the accuracy of risk perception in aviation risks among aviators.

    We introduce a focus+context method to visualize a complicated metro map of a modern city on a small displaying area. The context of our work is with regard the popularity of mobile devices. The best route to the destination, which can be obtained from the arrival time of trains, is highlighted. The stations on the route enjoy larger spaces, whereas the other stations are rendered smaller and closer to fit the whole map into a screen. To simplify the navigation and route planning for visitors, we formulate various map characteristics such as octilinear transportation lines and regular station distances into energy terms. We then solve for the optimal layout in a least squares sense. In addition, we label the names of stations that are on the route of a passenger according to human preferences, occlusions, and consistencies of label positions using the graph cuts method. Our system achieves real-time performance by being able to report instant information because of the carefully designed energy terms. We apply our method to layout a number of metro maps and show the results and timing statistics to demonstrate the feasibility of our technique. © 2011 IEEE

  17. Focusators for laser-branding

    A new method is investigated for synthesis of computer-generated optical elements: focusators that are able to focus the radial-symmetrical laser beam into complex focal contours, in particular into alphanumeric symbols. The method is based on decomposition of the focal contour into segments of straight lines and semi-circles, following corresponding spacing out of the focusator on elementary segments (concentric rings or sectors) and solution of the inverse task of focusing from focusator segments into corresponding elements of the focal contour. The results of numerical computing of the field from synthesized focusators into the letters are presented. The theoretical efficiency of the focusators discussed is no less than 85%. The amplitude masks and the results of operational studies of synthesized focusators are presented.

    Current patient safety policy focuses nursing on patient care goals, often overriding nurses' safety. Without understanding how nurses construct work health and safety (WHS), patient and nurse safety cannot be reconciled. Using ethnography, we examine social contexts of safety, studying 72 nurses across five Australian hospitals making decisions during patient encounters. In enacting safe practice, nurses used "frames" built from their contextual experiences to guide their behavior. Frames are produced by nurses, and they structure how nurses make sense of their work. Using thematic analysis, we identify four frames that inform nurses' decisions about WHS: (a) communicating builds knowledge, (b) experiencing situations guides decisions, (c) adapting procedures streamlines work, and (d) team working promotes safe working. Nurses' frames question current policy and practice by challenging how nurses' safety is positioned relative to patient safety. Recognizing these frames can assist the design and implementation of effective WHS management.

    The 2017 solar eclipse will be a natural phenomenon that will sweep across the United State would provide an excellent opportunity to observe and study the solar corona. The Citizens Continental Astronomical Telescopic Eclipse (CATE) Experiment directed my Matt Penn, intends to take advantage of this scientific opportunity by organizing 60 sites along the path of totality from Oregon to South Carolina to observe the eclipse and make a 90 min continuous video of the solar corona. The preliminary observation was done with the 2016 eclipse in Indonesia, with 5 sites along the path of totality. The sites were provided with an 80mm diameter Telescope with a 480mm focal length with an extension tube, Celestron equatorial mount, a CMOS camera, a Dell dual processor running Windows, GPS and an Arduino box, more details will be provided. I observed at the furthest east site in Ternate, Indonesia, with Dr. Donald Walter. The day of the eclipse we had clouds but still had a successful observation. The observation was successful with 4 out of the 5 sites collected eclipse data, due to weather the other site was not able to observe. The data was then collected and processed over the summer. To prepare for the observation in 2017, the 60 sites will be provided with the equipment, software and training. The groups will then practice by doing solar and lunar observations, where they will follow an almost identical procedure for the eclipse to do their observations. These test will increase our chances to have a successful observation among all sites. The focus will play a crucial role in this observation to provide a high quality image. Currently, a new focusing method using an image derivative method to provide quantitative feedback to the user is being developed. Finally, a Graphical User Interface is also being developed using the codes produces from the summer 2016 data analysis, to process the images from each site with minimal effort and produce quality scientific images
