    The purpose of this report is to detail the tasks accomplished as a NASA NIFS intern for the summer 2014 session. This internship opportunity is to develop an issue tracker Ruby on Rails web application to improve the communication of developmental anomalies between the Support Software Computer Software Configuration Item (CSCI) teams, System Build and Information Architecture. As many may know software development is an arduous, time consuming, collaborative effort. It involves nearly as much work designing, planning, collaborating, discussing, and resolving issues as effort expended in actual development. This internship opportunity was put in place to help alleviate the amount of time spent discussing issues such as bugs, missing tests, new requirements, and usability concerns that arise during development and throughout the life cycle of software applications once in production.

    Strip Tracker The Silicon Strip Tracker has maintained excellent operational performance during the 2011 data-taking period. The increase of instantaneous luminosity up to 1033 cm-2s-1 did not introduce any new issues in the detector. The detector has collected high-quality physics data with an uptime greater than 98%. Sources of downtime have been identified and problems were properly addressed. Improved firmware in the Front-End Driver (FED) firmware was deployed to increase the robustness of the readout against spurious extra frames coming from the detector. When a FED detects bad data, it goes into Out-Of-Sync (OOS) status, waits for a L1 resynchronisation command (resync) to clean up the culprit data and restarts. Resync commands are now sent automatically to the Strip Tracker when it signals OOS and, as a result, this source of downtime has been reduced significantly. The dead-time, caused by recoveries from OOS, accounts for less than 0.1%. Downtime was also found to be caused by a FED occasionally ge...

    Silicon strips During the first collisions the strip-Tracker operated with excellent performance and stability. The results obtained were very impressive and this exciting experience marked a fine end to another intense year. Several issues were identified during 2009 operations that could benefit from improvement: to suppress the increased output data volume when in STANDBY state (LV ON, HV OFF), which is due to the larger noise amplitudes when the sensors are unbiased; to reduce the strips configuration time; to increase the stability of the power system, particularly during state transitions, and to decrease the powering up time. The strip-Tracker FEDs now react to changes in the HV conditions of the strips. Upon a transition to STAND-BY, central DAQ starts a PAUSE-RESUME cycle and a flag is issued to the FEDSupervisor. This results in forcing the common mode noise artificially to the maximum value, which effectively suppresses the analogue data output. This forced offset is removed as soon as the strips ...

      Strip Tracker In the end of 2011, the Silicon Strip Tracker participated in the very successful heavy-ion collision data-taking. With zero downtime attributed to the Strip Tracker, CMS could achieve the excellent efficiency of 96%. Thus we were able to improve on the already good uptime during pp collisions, and completed an excellent year for the Strip Tracker. The shift of responsibility to raise the high voltages at the declaration of Stable Beams from the Tracker DOC to the central crew went smoothly. The new scheme is working reliably and we improved our automatic DQM and DCS SMS services. With this further improvement we plan to discontinue calling the TK DOC at each Stable Beam; so far the TK DOC personally checked all systems. The biggest effort of this Year-End Technical Stop was a comprehensive evaluation of the C6F14 cooling system performance with respect to future cold operation. The analysis allows a dedicated planning of system refurbishments to be executed during 2012 and LS1....

      Strip Tracker In general, the Strip Tracker is operating smoothly with the current peak instantaneous luminosity beyond 6.5E33, high L1 rate and large pile-up. With several improvements in automatic DQM checks and an enhanced SMS and e-mail service system plus additional audio alarms, we have reduced the work-load of our TK DOC and stopped the calls made at the beginning of each fill. We successfully collected more than two million cosmic tracks in peak mode during inter-fill periods before June, fulfilling the request from the Tracker alignment group. Around 500k cosmic tracks were also collected at zero Tesla. All planned special measurements, namely DCU calibration and I-V scans, have been taken during the YETS and other technical stops. A peak-mode run, a delay run and two HV scans have also been taken during early collisions at the initial low-lumi runs as well as during the fill where CMS had a problem with the magnet. The largest source of downtime comes from TIB-2.8.1 a.k.a. FED 101, ...

    The strip system has generally exhibited stable and high performance operation during the last six months of pp and heavy ion collisions. The up-time during pp collision from June onwards was 99.0% and during the first weeks of heavy-ion running we reached 99.7%. Most of the down-time during the proton runs came from Tracker DAQ problems. Spurious extra events from individual front-end channels caused ‘sync loss draining’ errors at the central DAQ system downstream of the Tracker FEDs. Once the problem was understood, new firmware that detects this error condition was installed on the FEDs. This has reduced the recovery procedure from this particular condition from a full reconfiguration requiring 170 s, to a simple re-synchronisation taking only ~1 s. We have also streamlined the instructions for the central DAQ shifters in order to minimise the time needed to decide the proper reaction to a given problem. The average down-time for problems triggered by the strip tracker DAQ is 395 s. Th...

    Strip Tracker Since the June CMS Week, the Silicon Strip Tracker has had another period of excellent detector operation with more than 97% system uptime. The focus on stable proton physics collection was fruitful, as CMS recorded greater than 5 fb–1 by the completion of the 2011 pp run. Following the November machine development and technical stop, the Strip Tracker now aims to provide the highest quality data during the heavy-ion run. The detector health, measured by the fraction of alive channels, is largely stable at around 97.8%. Recent failures include a TOB control ring, which now requires redundancy, and a TEC control ring with intermittent failures. These will be investigated during the Year-End Technical Stop. Critical services are very stable. The cooling system has a low total leak rate of less than 1 kg per day, and the power supply exchange rate is less than 1 unit per month. Two operational changes recently went into effect to optimise data-taking efficiency: (1) a tripped power su...

    The Tracker has continued to operate with excellent performance during this first period with 7 TeV collisions. Strips operations have been very smooth. The up-time during collisions was 98.5%, up to end of May, with a large fraction of the down-time coming during the planned fine-timing scan with early 7 TeV collisions. Pixels operations are also going very well, besides problems related to background beam-gas collisions where the particles produced generate very large clusters in the barrel modules. When CMS triggers on these events, the FEDs affected overflow and then timeout. Effort was mobilised very quickly to understand and mitigate this problem, with modifications made to the pixel FED firmware in order to provide automatic recovery. With operations becoming more and more routine at P5, Pixels have begun the transition to centrally attended operation, which means that the P5 shifters will no longer be required to be on duty. The strip-Tracker is also planning to make this transition at the end of Ju...

    Pixel Tracker Maintenance of the Pixel Tracker has been ongoing since it was extracted from inside CMS and safely stored at low temperatures in Pixel laboratory at Point 5 (see previous Bulletin).    All four half cylinders of the forward Pixel detector (FPIX) have been repaired and the failures have been understood. In October, a team of technicians from Fermilab replaced a total of three panels that were not repairable in place. The replacement of panels is a delicate operation that involves removing the half disks that hold the panels from the half cylinders, removing the damaged panels from the half disks, installing the new panels on the half disks, and finally putting the half disks back into the half cylinders and hooking up the cooling connections. The work was completed successfully. The same team also prepared the installation of the Phase 1 Pixel pilot blade system, installing a third half disk mechanics in the half cylinders; these half disks will host new Phase 1 P...

    The strip tracker took data very efficiently during 2010 with system availabilities of above 97% in the pp running and close to 100% during the heavy-ion running. The number of active channels in the readout is largely stable around 98%. The maintenance and development during the extended technical stop have been focussed on improving the operating conditions of the main silicon strip cooling plants SS1 and SS2, which have been items of concern (see last Bulletin). In order to stabilise and smooth the operation of SS1 and SS2, larger bypass valves and variable frequency drivers (VFDs) have been introduced. Possible noise induced by operation of the VFDs on other parts of CMS has been evaluated and no increased noise has been reported so far. The leak rate of every single line on SS2 was measured with the precise test-rig. Besides the known leaky lines, ten other SS2 lines were measured to leak between 120 g/day and 1200 g/day under the given test conditions, establishin...

    Pixels Tracker With the 2012 proton-proton run almost complete, the pixel detector continues to operate well in an environment with large pile-up and high L1 rate. During this period, the pixel detector has shown excellent stability, with the number of current active channels from each the BPIX and FPIX the same as from the first month of 2012 running, resulting in 96.3% of the detector active. This total includes the recovery of six FPIX channels, temporarily disabled due to an unexpected dependence on the magnetic field. From a dedicated study that identified a small crack in an optical cable connector, a repair was made which restored 120 ROCs in the FPIX. During 2012 there has been a close collaboration of the online operations with the offline studies, resulting in the first dedicated HV bias scans used for the pixel Lorentz Angle measurement. These scans help to better understand this important parameter that changes with temperature, irradiation, and bias voltage. This is in addition to all other s...

      Pixel Tracker Preparation of the newly built Pixel clean room in the radioprotection (RP) zone of SX5 has been proceeding at a steady clip since the beginning of 2013. The clean room is designed to provide a cold, dry, dust-free laboratory environment for storage and repairs of the CMS Pixel detector during LS1 and future LHC shutdown periods. To that end, it is required to have robust temperature and humidity control, standalone DAQ and DCS systems, and space for specialised silicon testing and repair equipment. Good progress has been made in delivering each of these items. The ongoing project of commissioning the clean room HVAC system has been a success so far. The clean room will be kept at 10–20 Pa above atmospheric pressure to ensure that contaminants flow out of the room.

    In the context of overseeing the quality of data, and as a result of the inherent complexity of projects such as CMIP5/6, it is a mandatory task to keep track of the status of datasets and the version evolution they sustain in their life-cycle. The ESdoc-errata project aims to keep track of the issues affecting specific versions of datasets/files. It enables users to resolve the history tree of each dataset/file enabling a better choice of the data used in their work based on the data status. The ES-doc-errata project has been designed and built on top of the Parent-IDentifiers handle service that will be deployed in the next iteration of the CMIP project, by ensuring maximum usability of ESGF ecosystem and encapsulated in the ES-doc structure. Consuming PIDs from handle service is guided by a specifically built algorithm that extracts meta-data regarding the issues that may or may not affect the quality of datasets/files and cause newer version to be published replacing older deprecated versions. This algorithm is able to deduce the nature of the flaws to the file granularity, that is of high value to the end-user. This new platform has been designed keeping in mind usability by end-users specialized in the data publishing process or other scientists requiring feedback on reliability of data required for their work. To this end, a specific set of rules and a code of conduct has been defined. A validation process ensures the quality of this newly introduced errata meta-data , an authentication safe-guard was implemented to prevent tampering with the archived data, and a wide variety of tools were put at users disposal to interact safely with the platform including a command-line client and a dedicated front-end.

  4. Public health workforce: challenges and policy issues

    Full Text Available Abstract This paper reviews the challenges facing the public health workforce in developing countries and the main policy issues that must be addressed in order to strengthen the public health workforce. The public health workforce is diverse and includes all those whose prime responsibility is the provision of core public health activities, irrespective of their organizational base. Although the public health workforce is central to the performance of health systems, very little is known about its composition, training or performance. The key policy question is: Should governments invest more in building and supporting the public health workforce and infrastructure to ensure the more effective functioning of health systems? Other questions concern: the nature of the public health workforce, including its size, composition, skills, training needs, current functions and performance; the appropriate roles of the workforce; and how the workforce can be strengthened to support new approaches to priority health problems. The available evidence to shed light on these policy issues is limited. The World Health Organization is supporting the development of evidence to inform discussion on the best approaches to strengthening public health capacity in developing countries. WHO's priorities are to build an evidence base on the size and structure of the public health workforce, beginning with ongoing data collection activities, and to map the current public health training programmes in developing countries and in Central and Eastern Europe. Other steps will include developing a consensus on the desired functions and activities of the public health workforce and developing a framework and methods for assisting countries to assess and enhance the performance of public health training institutions and of the public health workforce.

    In this paper I discuss how evidence on public policy is generated and in particular the issue of evaluation of public policies. In economics, the issue of attribution and the identification of causal links has recently received considerable attention. Important methodological issues have been tackled and new techniques have been proposed and used. Randomized Control Trials have become some sort of gold standard. However, they are not exempt from problems and have important limitations: in some case they cannot be constructed and, more generally, problems of external validity and transferability of results can be important. The paper then moves on to discuss the political economy of policy evaluations for policy evaluations to have an impact for the conduct of actual policy, it is important that the demand for evaluation comes directly from the policy making process and is generated endogenously within it. In this sense it is important that the institutional design of policy making is such that policy making institutions are incentivized to use rigorous evaluation in the process of designing policies and allocating resources to alternative options. Economists are currently involved in the design and evaluation of many policies, including policies about health, nutrition and education. The role they can play in these fields is not completely obvious. The paper argues that their main contribution is in the modelling of how individual reacts to incentives (including those provided by public policies).

    In October 2004, the Environics Research Group conducted a telephone survey of 608 adult Ontarians to collect information on matters regarding energy; consumer confidence and protection; responsibilities of the Ontario Energy Board; and consumer information preferences. This report summarizes the key findings of the survey. According to the survey, the most important electricity and natural gas issue was identified as being price and cost issues, followed by reliability of supply, conservation, keeping utilities publicly owned, finding renewable sources of energy, and over-consumption. The survey revealed that Ontarians show much interest in conserving energy to save money, to protect the environment and ensure future energy supply, but they are generally sceptical that their interests are being protected on electricity and natural gas price issues. At least 9 in 10 Ontarians consider the tasks of the Ontario Energy Board to be important. The majority of Ontarians prefer to receive energy conservation information through the mail and from public regulators over a government department or a company. 10 tabs.

    Control of anthropogenic noise in many terrestrial and underwater environments is crucial for maintaining communication, health, and normal behavior of animals. Noise can be an issue for any species; usually, however, endangered and threatened species and marine mammals are the ones provided legal protection under the Endangered Species Act and/or the Marine Mammal Protection Act. Recent substantiated noise effects in the ocean have received much publicity and generated a more global approach to noise control. However, there are also cases where publicity was not accompanied by scientific data substantiating effects (e.g., an incident involving a $1 million noise barrier installed to protect passerine birds). The public and environmental managers have had difficulty developing adequate guidelines not only because necessary data are often lacking, but also because the manner in which funding is allocated-noise-producing agencies or private organizations are often pressured to fund studies-gives rise to inevitable conflicts of interest (or the perception thereof). Examples of recent noise-related controversies will be presented to examine the role of scientists, engineers, and professional organizations such as ASA in dealing with conflicts of interest and formulating public policy.

But despite the slight delay, Friday 17 February was lovingly embraced as 'Conception Day,' when dozens of physicists and engineers from the international collaboration gathered to witness the insertion of the ATLAS semiconductor tracker into the transition radiation tracker, a major milestone in the assembly of the experiment's inner detector. With just millimeters of room for error, the cylindrical trackers were slid into each other as inner detector integration coordinator Heinz Pernegger issued commands and scientists held out flashlights, lay on their backs and stood on ladders to take careful measurements. Each tracker is the result of about 10 years of international ...

    A series of important milestones have been passed during the last 3 months. With the delivery of refurbished cooling systems, pixels and strip systems have been brought back into operation after long shutdowns. Pixels has been operating since reinsertion of FPIX in April, and has been running at 4°C since May 16 when the bulkhead thermal screen was commissioned. More recently, on June 10 the Strip Tracker was powered up in its entirety, with cooling fluid circulating at 4°C, allowing commissioning of the Strip Tracker to proceed at full speed. The full Tracker is well on course to be ready for CRAFT, with Strip Tracker readout operation in ‘peak’ mode remaining also on track to be ready for beam operations in the Autumn in ‘deconvolution’ readout mode. The main Tracker activity during the shutdown was the cooling plant refurbishment for Strips and Pixels systems.

    The clear highlight of recent months was switching on the Tracker to capture the first LHC collisions with 450GeV beams. This was during the first trial run of the LHC on 23rd November. On that day, the Tracker Outer Barrel (TOB) was powered and the detector performance was excellent, in accord with our expectations. Since then, the full Tracker, strips and pixels, has been powered up during “quiet” beam periods when there was judged to be little risk of damage due to sudden beam losses. All Tracker systems performed very well, considering the beam and trigger conditions in place, and we now eagerly anticipate the first collisions with stable beams. Besides this very intense and exciting recent period there has been a lot of other activity in the last 6 months. The full Tracker participated in CRAFT09 and operations of all systems went very smoothly for both pixels and strips, validating all the meticulous work that had taking place during the long shutdown, the subsequent re-commissionin...

    This study aims to elucidate the intricate interplay between public attention and public emotion toward multiple social issues. A theoretical framework is developed based on three perspectives including endogenous affect hypothesis, affect transfer hypothesis, and affective intelligence theory. Large-scale longitudinal data with 265 million tweets on five social issues are analyzed using a time series analytical approach. Public attention on social issues can influence public emotion on the issue per se. Social issues interact with one another to attract public attention in both cooperative and competitive ways. Instead of a direct transfer from public emotion to public attention, the public emotion toward a social issue moderates the interaction between the issue and other issue(s). PMID:28081117

    Hadderman, Margaret

    This document provides an overview of public-school voucher plans. Educational vouchers originated in the 1960s when Milton Friedman argued that vouchers would improve educational efficiency. Parents would receive the equivalent of per-pupil expenditures in the form of vouchers that could then be used at any school, either public and private. But…

  18. INNER TRACKER

    CERN Multimedia

    Peter Sharp

    In March the Silicon Strip Detector had been successfully connected to the PP1 patch panels on the CMS Cryostat, and every thing had been prepared to check out the Tracker and commission it with CMS with the ambition of joining the CMS Global Cosmic Run in April.  There followed serious problems with the cooling plant which through tremendous effort have been overcome and recently allowed commissioning of the tracker to proceed. In November 2007 there had been a failure of the heat exchanger in one of the seven cooling plants in the UXC cavern. After an analysis of the failure it was decided to replace this heat exchanger with a well-proven commercial heat exchanger and to re-commission the system. Re-commissioning the system proved to be more difficult than anticipated as on May 8 there was a second failure of a heat exchanger, in the main chiller plant in the USC service cavern. The analysis of the failure showed it was very similar to the previous failure. It was decided to replace all the heat ...

    2015-06-01

    This special issue of the Journal of Genetic Counseling is dedicated to public health genetics and genomics. The seventeen papers featured in this issue span such topics as genetic counselors in public health roles, newborn screening, population screening, ethics, and health beliefs and behaviors. In this introduction to the special issue, we review some history of public health genetics and genomics, present the Centers for Disease Control and Prevention's "10 Essential Public Health Services" with associated genetics specific recommendations and priorities, and briefly overview how each article ties into the world of public health genetics and genomics. We hope this issue encourages genetic counselors to visualize their ever expanding and important roles in public health genetics and genomics, as well as their contributions to improving population health.

  1. Tackling poor parenting: a public health issue.

    Science.gov (United States)

    Poole, Judith

    2003-01-01

    The adverse consequences associated with poor parenting persist down the generations and are a problem for society as well as individuals. The author cites evidence suggesting that in many cases poor parenting is associated with socioeconomic deprivation, including health inequalities. She argues that most parents (especially mothers, as the main child carers) are motivated to do their best for their children but that many families struggle against poverty. Poor parenting skills may be a product of poverty and social exclusion rather than the fault of individual parents. A public health approach, based on partnership with parents to meet their expressed needs in appropriate ways, could offer a constructive way forward.

  2. Science Communication for the Public Understanding of Nuclear Issues

    Energy Technology Data Exchange (ETDEWEB)

    Cho, Seongkyung [Myungji Univ., Yongin (Korea, Republic of)

    2006-04-15

    Uncertainty, stigma, risk perception, and value judgment represent characteristics of nuclear issues in the public arena. Nuclear issue, in the public arena, is a kind of risk rather than technology that we are willing to use for good purpose. There are uncertainty, stigma, risk perception, and value judgment as characteristics of nuclear. The notion of the public, here is of active, sensitive, and sensible citizens, with power and influence. The public understands nuclear issues less through direct experience or education than through the filter of mass media. Trust has been a key issue on public understanding of nuclear issues. Trust belongs to human. The public understanding process includes perception, interpretation, and evaluation. Therefore, science communication is needed for public understanding. Unfortunately, science communication is rarely performed well, nowadays, There are three important actors-the public, experts, and media. Effective science communication means finding comprehensible ways of presenting opaque and complex nuclear issues. It makes new and strong demands on experts. In order to meet that requirement, experts should fulfill their duty about developing nuclear technology for good purpose, understand the public before expecting the public to understand nuclear issues, accept the unique culture of the media process, take the responsibility for any consequence which nuclear technologies give rise to, communicate with an access route based on sensibility and rationality, have a flexible angle in the science communication process, get creative leadership for the communication process with deliberation and disagreement, make efficient use of various science technologies for science communication. We should try to proceed with patience, because science communication makes for a more credible society.

  3. Apartheid as a public mental health issue.

    Science.gov (United States)

    Dommisse, J

    1985-01-01

    The most serious hazard to the physical and mental health of the majority rural poor black population in South Africa is caused by the ruling wealthy white minority's policy of apartheid. Forced removals and dumping of millions of people into small, disconnected, barren, poor reserve areas, bereft of adequate medical, psychiatric and public health services (the 'final solution' of the 'native problem') causes widespread malnutrition, infectious and other diseases, and high mortality and mental-illness rates. Blacks and progressive whites are banned, terrorized, detained without trial, tortured, and murdered by the state; the Africans are not only disfranchised but are now also being denationalized and deprived of their ancient birthright to this richly-endowed part of Africa. Acceptance of this modern version of Naziism by the World Psychiatric Association and the World Medical Association, in the face of adequate information provided by the United Nations, its agency the World Health Organization, the American Psychiatric Association, and numerous other agencies and reports, needs urgent examination and decisive action.

    Full Text Available December 3, 2015, the President of Russia Vladimir Putin delivered his annual Address to the Federal Assembly. Having analyzed the Address, experts pointed out the President’s worries and concerns about the efficiency of execution of development priorities he had set out. Vladimir Putin repeatedly urged the Government to implement effective measures on specific issues in the shortest time possible. However, it has not been done so far; therefore, we think that the President’s concern is reasonable. Recent research carried out by ISEDT RAS reveals certain alarming trends in the social health of the regional society

    Gollust, Sarah E.; Goold, Susan D.; Jacobson, Peter D.

    2009-01-01

    Objectives. We sought to ascertain the types of ethical challenges public health practitioners face in practice and to identify approaches used to resolve such challenges. Methods. We conducted 45 semistructured interviews with public health practitioners across a range of occupations (e.g., health officers, medical directors, sanitarians, nurses) at 13 health departments in Michigan. Results. Through qualitative analysis, we identified 5 broad categories of ethical issues common across occupations and locations: (1) determining appropriate use of public health authority, (2) making decisions related to resource allocation, (3) negotiating political interference in public health practice, (4) ensuring standards of quality of care, and (5) questioning the role or scope of public health. Participants cited a variety of values guiding their decision-making that did not coalesce around core values often associated with public health, such as social justice or utilitarianism. Public health practitioners relied on consultations with colleagues to resolve challenges, infrequently using frameworks for decision-making. Conclusions. Public health practitioners showed a nuanced understanding of ethical issues and navigated ethical challenges with minimal formal assistance. Decision-making guides that are empirically informed and tailored for practitioners might have some value. PMID:19059850

    Science.gov (United States)

    Patterson, George T

    2013-01-01

    A significant literature identifies the policy, economic, health, and social challenges that confront released prisoners. This literature also describes the public health and public safety risks associated with prisoner reentry, provides recommendations for improving the reentry process, and describes the effectiveness of prison-based programs on recidivism rates. Public health and public safety risks are particularly significant in communities where large numbers of prisoners are released and few evidence-based services exist. The purpose of this article is to describe the public health and public safety risks that released prisoners experience when they reenter communities, and to discuss the social justice issues relevant for social work practice.

  1. Public engagement with CCS: barriers, key issues and ways forward

    Science.gov (United States)

    Xenias, Dimitrios

    2017-04-01

    Although Carbon Capture and Storage (CCS) is recognised as a crucial transition technology to a low-carbon world, it has not been popular with the public or some governments (e.g. the UK). Also, despite its use in industrial processes for decades, CCS remains and unfamiliar technology for most publics. It is therefore important to foster top-down and bottom-up acceptance of large scale CCS. In an exploratory round of interviews we canvassed the views of British, Dutch, German and Norwegian experts (N=13) with previous experience in public engagement with CCS. They identified barriers and drivers for CCS deployment and public engagement with CCS. Thematic analysis revealed a small number of recurrent issues, including: (a) lack of political leadership on CCS; (b) lack of public knowledge on relevant technologies and (c) difficulty communicating why CCS is necessary. Emphasis on these barriers varied with the level of experts' engagement with the public. More interestingly, although most experts agreed on the importance of public engagement, their views divided between 'why' engage and 'how' best to do this. In a subsequent expert survey (N=99) interview findings were reinforced: public support was seen as important for CCS roll-out (72%), though lower than political support and funding. The survey also showed that local public was expected to experience most risks, while global public will experience most benefits; whereas local business is seen to benefit more than global. Experts were overwhelmingly positive about CCS - risks outweigh benefits, and are confident that CCS will play a major role in climate change mitigation (along with reduced energy demand and renewables). These findings will be expanded on and triangulated in a follow-up public survey which will benefit those involved with public engagement with CCS.

  2. Investigating differences in public support for gay rights issues.

    Science.gov (United States)

    Schwartz, Joseph

    2010-01-01

    Public opinion surrounding two of the most well-known gay rights issues-same-sex marriage and adoption by gays and lesbians-varies widely: About 30% of the public favors same-sex marriage, while about 50% favors adoption. The purpose of this study was to examine and compare the demographic variables that predict attitudes toward same-sex marriage and adoption by gays and lesbians. Political ideology and attendance at religious services emerged as the strongest predictors. However, a close examination of the two issues shows that there were important differences between them. These differences may aid gay rights advocates in crafting media campaigns designed to increase support for same-sex marriage.

    On December 15, 2003, the Centers for Public Health Preparedness at the University of Minnesota and the University of Iowa convened the "Public Health and Terrorism Preparedness: Cross-Border Issues Roundtable." The purpose of the roundtable was to gather public health professionals and government agency representatives at the state, provincial, and local levels to identify unmet cross-border emergency preparedness and response needs and develop strategies for addressing these needs. Representatives from six state and local public health departments and three provincial governments were invited to identify cross-border needs and issues using a nominal group process. The result of the roundtable was identification of the needs considered most important and most doable across all the focus groups. The need to collaborate on and exchange plans and protocols among agencies was identified as most important and most doable across all groups. Development of contact protocols and creation and maintenance of a contact database was also considered important and doable for a majority of groups. Other needs ranked important across the majority of groups included specific isolation and quarantine protocols for multi-state responses; a system for rapid and secure exchange of information; specific protocols for sharing human resources across borders, including emergency credentials for physicians and health care workers; and a specific protocol to coordinate Strategic National Stockpile mechanisms across border communities.

  4. Rural Public Libraries and Digital Inclusion: Issues and Challenges

    Directory of Open Access Journals (Sweden)

    Brian Real

    2014-03-01

    Full Text Available Rural public libraries have been relatively understudied when compared to public libraries as a whole. Data are available to show that rural libraries lag behind their urban and suburban counterparts in technology service offerings, but the full meaning and impact of such disparities is unclear. The authors combine data from the Public Library Technology and Access Study with data from smaller studies to provide greater insight to these issues. By filtering these data through the Digital Inclusion framework, it becomes clear that disparities between rural and non-rural libraries are not merely a problem of weaker technological infrastructure. Instead, rural libraries cannot reach their full customer service potential because of lower staffing (but not lower staff dedication and funding mechanisms that rely primarily on local monies. The authors suggest possible solutions to these disparities, while also discussing the barriers that must be overcome before such solutions can be implemented.

    Directory of Open Access Journals (Sweden)

    Annette Kamp

    2013-05-01

    Full Text Available Work in the public sector has been changing dramatically in recent decades. Reforms aimed at increasing the efficiency of public services have been extensive in the Nordic countries and elsewhere since the 1980s. The reforms and changes have to a large extent been associated with so-called New Public Management (NPM principles, emphasizing the market as a central coordination mechanism. Consequently, public institutions have been restructured, their services are standardized and commodified, and market-like relationships between them have been created. In order to create markets and transform citizens into customers on a market, outsourcing and privatization have been stimulated (Blomqvist & Rothstein 2000, Busch et al 2005, Christensen & Lægreid 2007, Greve 2003. At the same time, traditional Weberian bureaucratic principles are still viable and even enhanced within the sector, for instance, as a consequence of the use of contracts as a means of managing public organizations (Greve 2008. Lately, large reforms aimed at centralized coordination of different service providers, such as the integration of the Norwegian welfare administration, have been labeled post-NPM reforms by some researchers. The implication of all these parallel tendencies is that the institutional and organizational landscape surrounding the work situations of employees in the public sector have become increasingly complex, some call them hybrid,  putting a variety of conflicting pressures on the performance of work within the sector (Christensen & Lægreid 2011, Hasselbladh et al. 2008. In this special issue, we explore some of the consequences of these structural and normative changes on the work of public sector employees in different sectors and contexts (...

  11. [Mixed methods research in public health: issues and illustration].

    Science.gov (United States)

    Guével, Marie-Renée; Pommier, Jeanine

    2012-01-01

    For many years, researchers in a range of fields have combined quantitative and qualitative methods. However, the combined use of quantitative and qualitative methods has only recently been conceptualized and defined as mixed methods research. Some authors have described the emerging field as a third methodological tradition (in addition to the qualitative and quantitative traditions). Mixed methods research combines different perspectives and facilitates the study of complex interventions or programs, particularly in public health, an area where interdisciplinarity is critical. However, the existing literature is primarily in English. By contrast, the literature in French remains limited. The purpose of this paper is to present the emergence of mixed methods research for francophone public health specialists. A literature review was conducted to identify the main characteristics of mixed methods research. The results provide an overall picture of the mixed methods approach through its history, definitions, and applications, and highlight the tools developed to clarify the approach (typologies) and to implement it (integration of results and quality standards). The tools highlighted in the literature review are illustrated by a study conducted in France. Mixed methods research opens new possibilities for examining complex research questions and provides relevant and promising opportunities for addressing current public health issues in France.

  15. Public opinion on policy issues in genetics and genomics.

    Science.gov (United States)

    Almeling, Rene; Gadarian, Shana Kushner

    2014-06-01

    The aim of this study was to examine public opinion on major policy issues in genetics and genomics, including federal spending on genetic research, the perceived significance of the Genetic Information Nondiscrimination Act of 2008, and whether clinicians should be involved in direct-to-consumer genetic testing. This was a survey with a nationally representative sample of 2,100 American adults administered by the nonpartisan research firm YouGov in January 2011. The majority of the respondents (57%) believe that the federal government should spend more on genetic research, 82% rank the 2008 antidiscrimination law as "important," and 65% say that clinicians should be involved in explaining genetic test results (contra the practice of some direct-to-consumer companies). On all three policy issues, gender and political party affiliation were statistically significantly associated with respondents' views, whereas race/ethnicity and education were less consistently associated with policy opinions. Americans demonstrate widespread support for scientific research on genetics, laws protecting citizens against genetic discrimination, and the need to involve medical professionals in the process of genetic testing. These results are useful for scientists designing research projects, clinicians interacting with patients, professional organizations lobbying for resources, federal agencies setting budget priorities, and legislators designing regulation.

  16. Albinism in Africa as a public health issue

    Directory of Open Access Journals (Sweden)

    Hong Esther S

    2006-08-01

    Full Text Available Abstract Background Oculocutaneous albinism (OCA is a genetically inherited autosomal recessive condition and OCA2, tyrosine-positive albinism, is the most prevalent type found throughout Africa. Due to the lack of melanin, people with albinism are more susceptible to the harmful effects of ultraviolet radiation exposure. This population must deal with issues such as photophobia, decreased visual acuity, extreme sun sensitivity and skin cancer. People with albinism also face social discrimination as a result of their difference in appearance. The World Health Organization is currently investigating the issues concerning this vulnerable population. Methods Systematic electronic search of articles in PubMed concerning albinism in Africa. Furthermore, a World Health Organization (WHO pilot survey of albinism was drafted in English, French and Portuguese, and distributed to African countries through WHO African Regional Offices (AFRO in an attempt to gather further information on albinism. Results Epidemiologic data on albinism, such as prevalence, were available for South Africa, Zimbabwe, Tanzania and Nigeria. Prevalences as high as 1 in 1,000 were reported for selected populations in Zimbabwe and other specific ethnic groups in Southern Africa. An overall estimate of albinism prevalences ranges from 1/5,000 – 1/15,000. In addition, both the literature review and the survey underscored the medical and social issues facing people with albinism. Conclusion The estimated prevalence of albinism suggests the existence of tens of thousands of people living with albinism in Africa. This finding reiterates the need for increased awareness of and public health interventions for albinism in order to better address the medical, psychological and social needs of this vulnerable population.

    2016-01-01

    The CMS Tracker was repaired, recalibrated and commissioned successfully for the second run of Large Hadron Collider. In 2015 the Tracker performed well with improved hit efficiency and spatial resolution compared to Run I. Operations successfully transitioned to lower temperatures after commissioning environmental control and monitoring. This year the detector is expected to withstand luminosities that are beyond its design limits and will need a combined effort of both online and offline team to yield the high quality data that is required to reach our physics goals. We present the experience gained during the second run of the LHC and show the latest performance results of the CMS Tracker.

    Full Text Available Needs assessment in local public institutions was not very present so far in a systematic manner in Romanian specialized literature on administrative reform. Current study uses interviews with candidates for a public administration master program to investigate civil servants motivation of pursuing graduatelevel studies and their perception on current needs of the work in local public institutions. Motivation for pursuing graduate studies is located mainly on the need to update and diversify their professional knowledge, and not as much on promotion-related reasons. The perceived needs are related to management of public institutions, structure of information system, legislation and European integration, human resource management and public relations.

    The wearable consumer health devices can be mainly divided into activity trackers, sleep trackers, and stress management devices. These devices are widely advertised to provide positive effects on the user's daily behaviours and overall heath. However, objective evidence supporting these claims appears to be missing. The goal of this study was to review available evidence pertaining to performance of activity trackers. A comprehensive review of available information has been conducted for seven representative devices and the validity of marketing claims was assessed. The device assessment was based on availability of verified output metrics, theoretical frameworks, systematic evaluation, and FDA clearance. The review identified critical absence of supporting evidence of advertised functions and benefits for the majority of the devices. Six out of seven devices did not provide any information on sensor accuracy and output validity at all. Possible underestimation or overestimation of specific health indicators reported to consumers was not clearly disclosed to the public. Furthermore, significant limitations of these devices which can be categorized into user restrictions, user responsibilities and company disclaimers could not be easily found or comprehended by unsophisticated users and may represent a serious health hazard.

  14. Public Discourse on Human Trafficking in International Issue Arenas

    Directory of Open Access Journals (Sweden)

    Niina Meriläinen

    2015-01-01

    Full Text Available The purpose of this study is to better understand how the complex problem of human trafficking is addressed in international debates. How the discussion about human trafficking develops and how it is debated ultimately influences how the decision-making process unfolds. In order to understand the formation of public policy and laws, therefore, it is important to study the debate that occurs prior to decision making. This analysis focuses on the narratives used by major, well-established human rights and political actors that argue for necessary actions to be undertaken—such as the formation of new policies and laws in the European Union—as an attempt to protect citizens of the EU and other regions in the world from becoming victims of trafficking networks. Our research examines how the topic of human trafficking is framed and how this framework is intertwined in the debate with other social problems. We focus on how human trafficking is discussed by two well-established human rights Non-Governmental Organizations (NGOs, Amnesty International (Amnesty and Human Rights Watch (HRW, in addition to the European Parliament (EP. The research questions for this study include: (1 In what context is human trafficking discussed by the three actors? (2 How do these actors frame the definition of human trafficking in their presentations? To answer these questions, we have conducted a systematic content analysis of documents that include official statements and research reports of the NGOs, as well as resolutions and recommendations of the EP. Altogether, 240 documents were analyzed in detail. These findings indicate that the two human rights organizations, Amnesty and Human Rights Watch, along with the European Parliament, all address human trafficking as an important social problem, albeit to varying degrees. Each actor has a different method of correlating human trafficking with many other social problems, thereby emphasizing different causes and

However, periodontal treatment in pregnant women is not included in the POS.General medical practitioners and specialists could play a pivotal role in the promotion of oral health. However, most doctors do not know general health periodontitis implications, are not trained to diagnose periodontal disease, and are not sensitized to refer high-risk patients as diabetic and pregnant women to the dentist. The perception of medicine and dentistry as individual health sciences has made difficult the development of an effective oral health policy to improve oral health indicators.It is necessary to implement cost-effective policies of public health to decrease oral health inequalities in Colombian population. Oral health goals in Colombia can only be accomplished by a public health strategy including education programs to the community, facilitating the dentist-physician collaboration, increasing access of the population to dentist, and give financial support to interdisciplinary research projects. Additionally, periodontitis treatment should be included in the POS, especially for diabetic patients and pregnant women. This year the Universidad del Valle will present the anterior proposal to the Colombian Association of Dentistry Faculties (ACFO, to the Colombian Association of Medical Faculties (ASCOFAME and to the Colombian Association of Nurses Faculties (ASCOFAEN with the aim of to elaborate a recommendations manuscript for the Ministry of Health consideration on this issue.

According to the author the monitoring process should involve the greatest possible range of subjects and the controlling measures are to be taken in a transparent and open manner. Therefore forms of citizen participation in public control should be investigated from the standpoint of the principle of openness of local government. Methods the universal dialectic method which was applied to the analysis of norms of the Federal law quotOn fundamentals of public control in the Russian Federationquot which is the legal base for the implementation of the institution of public control. When studying the problem of adequate legal regulation of the control institution the formal legal method was also used. Other methods were used for evaluation of the acquired knowledge in particular comparative legal and systemicstructural methods. Results on the basis of legal norms analysis based on the legal nature of the local government institution as the level of public authorities which is closest to the citizens the conclusion was made about the lack of legal regulation relating to the public control subjects in municipalities. The numerous public organizations operating in local communities were not fixed by legislative norms as subjects of public control. Scientific novelty the author has grounded the proposals for amending the abovementioned Federal law the legislation of Federation subjects and the municipal regulations by adding a number of new subjects of public control inherent to the municipal level.

    2010-06-01

    Full Text Available Abstract Background Climate change is taking a toll on human health, and some leaders in the public health community have urged their colleagues to give voice to its health implications. Previous research has shown that Americans are only dimly aware of the health implications of climate change, yet the literature on issue framing suggests that providing a novel frame - such as human health - may be potentially useful in enhancing public engagement. We conducted an exploratory study in the United States of people's reactions to a public health-framed short essay on climate change. Methods U.S. adult respondents (n = 70, stratified by six previously identified audience segments, read the essay and were asked to highlight in green or pink any portions of the essay they found "especially clear and helpful" or alternatively "especially confusing or unhelpful." Two dependent measures were created: a composite sentence-specific score based on reactions to all 18 sentences in the essay; and respondents' general reactions to the essay that were coded for valence (positive, neutral, or negative. We tested the hypothesis that five of the six audience segments would respond positively to the essay on both dependent measures. Results There was clear evidence that two of the five segments responded positively to the public health essay, and mixed evidence that two other responded positively. There was limited evidence that the fifth segment responded positively. Post-hoc analysis showed that five of the six segments responded more positively to information about the health benefits associated with mitigation-related policy actions than to information about the health risks of climate change. Conclusions Presentations about climate change that encourage people to consider its human health relevance appear likely to provide many Americans with a useful and engaging new frame of reference.

    Spach, Miléna

    2016-10-19

    Objective: To analyse the impact of the alcohol market on the implementation of strong-willed public alcohol abuse prevention policies based on a critical review of the literature. Method: Documentary research and analysis of the alcohol market economic data were performed. An overview of public alcohol abuse prevention policies was conducted from a historical perspective by distinguishing drunkenness control policies, protection of vulnerable populations, and the fight against drink driving and drinking in the workplace. Results: Public alcohol abuse prevention policies are primarily designed to reduce the harmful consequences of alcohol occurring as a result of a drinking episode (motor vehicle accident, highway accidents, etc.), while neglecting the long-term consequences (cancer, cirrhosis, etc.). Moreover, while taxation is one of the major public health tools used to reduce the costs of alcohol-related damage on society, the State exercises legislative and tax protection for alcoholic beverages produced in France. In particular, wine benefits from a lower tax rate than other stronger forms of alcohol (spirits, liquors, etc.). The economic weight of the alcohol market can provide an explanation for these public alcohol abuse prevention policies. Conclusion: In view of the mortality caused by alcohol abuse, France must implement a proactive public policy. An alcohol taxation policy based on the alcohol content, a minimum unit pricing for alcohol, or higher taxes on alcohol are public policies that could be considered in order to reduce alcohol-related mortality.

    The initial objectives of this effort were to provide a hardware and software platform that can address the requirements for the accountability of classified removable electronic media and vault access logging. The Media Tracker system software assists classified media custodian in managing vault access logging and Media Tracking to prevent the inadvertent violation of rules or policies for the access to a restricted area and the movement and use of tracked items. The MediaTracker system includes the software tools to track and account for high consequence security assets and high value items. The overall benefits include: (1) real-time access to the disposition of all Classified Removable Electronic Media (CREM), (2) streamlined security procedures and requirements, (3) removal of ambiguity and managerial inconsistencies, (4) prevention of incidents that can and should be prevented, (5) alignment with the DOE's initiative to achieve improvements in security and facility operations through technology deployment, and (6) enhanced individual responsibility by providing a consistent method of dealing with daily responsibilities. In response to initiatives to enhance the control of classified removable electronic media (CREM), the Media Tracker software suite was developed, piloted and implemented at the Los Alamos National Laboratory beginning in July 2000. The Media Tracker software suite assists in the accountability and tracking of CREM and other high-value assets. One component of the MediaTracker software suite provides a Laboratory-approved media tracking system. Using commercial touch screen and bar code technology, the MediaTracker (MT) component of the MediaTracker software suite provides an efficient and effective means to meet current Laboratory requirements and provides new-engineered controls to help assure compliance with those requirements. It also establishes a computer infrastructure at vault entrances for vault access logging, and can

    Malaysia had considered nuclear energy as an option for future electricity generation during the 9th Malaysia Development Plan. Since 2009, Malaysia had implemented a number of important preparatory steps towards this goal, including the establishment of Nuclear Power Corporation of Malaysia (MNPC) as first Nuclear Energy Programme Implementing Organization (NEPIO) in Malaysia. In light of the establishment of MNPC, the National Nuclear Policy was formulated in 2010 and a new comprehensive nuclear law to replace the existing Atomic Energy Licensing Act (Act 304) is currently in the pipeline. Internationally, public acceptance is generally used to gauge the acceptance of nuclear energy by the public whenever a government decides to engage in nuclear energy. A public survey was conducted in between 14 March 2016 to 10 May 2016 focusing on the Malaysian public acceptance and perception towards the implementation of nuclear energy in Malaysia. The methodology of this research was aim on finding an overview of the general knowledge, public-relation recommendation, perception and acceptance of Malaysian towards the nuclear power development program. The combination of information gathered from this study can be interpreted as an indication of the complexity surrounding the development of nuclear energy and its relationship with the unique background of Malaysian demography. This paper will focus mainly on energy-related section in the survey in comparison with nuclear energy.

    Dr. Karen K. Petersen

    2009-01-01

    Full Text Available Lamenting the lack of public awareness of international events and U.S. foreign policy is not a particularly novel exercise; yet, explaining the process by which issues enter and exit the public realm remains a challenging endeavor. Despite contributions from researchers working in international relations and mass communication, explaining public inattentiveness continues to vex scholars. However, in his article, "Up and Down with Ecology: The 'Issue-Attention Cycle,'" Anthony Downs provides a parsimonious and tractable model of public opinion that can be applied to foreign policy issues.1 While Downs concerns himself exclusively with domestic issues, particularly environmental issues, his model has thepotential to contribute to our understanding of the relationship between the public and policymakers over critical issues such as international terrorism. With minor modifications, the model has the potential to explain public support for failed foreign policies as well. Downs' model, when applied to international terrorism, explains why policymakers seek simple solutions, why the public supports such solutions, and why the media fail to provide meaningful coverage of intractable issues such as international terrorism. Before discussing Downs' model, the basic tenets and shortcomings of some of the more prevalent theories of the relationship between public opinion and foreign policy are discussed below.

    2016-12-01

    Modern-day slave labor is one of the most pernicious and persistent social problems in Brazil. In the light of the need to implement a national occupational health policy, this paper discusses slave labor as a public health concern, highlighting possibilities for broadening strategies for vigilance and comprehensive care for this specific working population. Exploratory qualitative research was carried out based on the "social construction of reality" proposed by Lenoir, Berger and Luckmann. The investigation consisted of a theoretical review of modern-day slave labor on the national and international scene within the scope of the human, social and public health sciences and an analysis of social and political practices to tackle modern-day slave labor was conducted in the State of Rio de Janeiro. Semi-structured individual and group interviews with workers and representatives of social movements and public institutions were organized. The results reveal the theoretical and practical dimensions of slave labor and its relations with the health field and highlight the role and potential of public health in the enhancing of vigilance practices and health care of workers subjected to these chronic social conditions.

  6. ATLAS Transition Radiation Tracker

    CERN Multimedia

    2006-01-01

    The ATLAS transition radiation tracker is made of 300'000 straw tubes, up to 144cm long. Filled with a gas mixture and threaded with a wire, each straw is a complete mini-detector in its own right. An electric field is applied between the wire and the outside wall of the straw. As particles pass through, they collide with atoms in the gas, knocking out electrons. The avalanche of electrons is detected as an electrical signal on the wire in the centre. The tracker plays two important roles. Firstly, it makes more position measurements, giving more dots for the computers to join up to recreate the particle tracks. Also, together with the ATLAS calorimeters, it distinguishes between different types of particles depending on whether they emit radiation as they make the transition from the surrounding foil into the straws.

    This paper describes the Silicon microstrip Tracker of the CMS experiment at LHC. It consists of a barrel part with 5 layers and two endcaps with 10 disks each. About 10 000 single-sided equivalent modules have to be built, each one carrying two daisy-chained silicon detectors and their front-end electronics. Back-to-back modules are used to read-out the radial coordinate. The tracker will be operated in an environment kept at a temperature of T=-10 deg. C to minimize the Si sensors radiation damage. Heavily irradiated detectors will be safely operated due to the high-voltage capability of the sensors. Full-size mechanical prototypes have been built to check the system aspects before starting the construction.

  10. Robust correlation tracker

    Indian Academy of Sciences (India)

    2001-06-01

    Correlation tracking plays an important role in the automation of weapon systems. Area correlation is an effective technique for tracking targets that have neither prominent features nor high contrast with the background and the ‘target’ can even be an area or a scene of interest. Even though this technique is robust under varying conditions of target background and light conditions, it has some problems like target drift and false registration. When the tracker or target is moving, the registration point drifts due to the discrete pixel size and aspect angle change. In this research work, an attempt has been made to improve the performance of a correlation tracker for tracking ground targets with very poor contrast. In the present work only the CCD visible images with very poor target to background contrast are considered. Applying novel linear and nonlinear filters, the problems present in the correlation tracker are overcome. Confidence and redundancy measures have been proposed to improve the performance by detecting misregistration. The proposed algorithm is tested on different sequences of images and its performance is satisfactory.

  11. Constructing public oral health policies in Brazil: issues for reflection

    2012-01-01

    Full Text Available This paper addresses the construction of public oral health policies in Brazil by reviewing the available literature. It includes a discussion of the social responses given by the Brazilian State to oral health policies and the relationship of these responses with the ideological oral health movements that have developed globally, and that have specifically influenced oral health policies in Brazil. The influence of these movements has affected a series of hegemonic practices originating from both Market Dentistry and Preventive and Social Dentistry in Brazil. Among the state activities that have been set into motion, the following stand out: the drafting of a law to regulate the fluoridation of the public water supply, and the fluoridation of commercial toothpaste in Brazil; epidemiological surveys to analyze the status of the Brazilian population's oral health; the inclusion of oral health in the Family Health Strategy (Estratégia de Saúde da Família - ESF; the drawing up of the National Oral Health Policy, Smiling Brazil (Brasil Sorridente. From the literature consulted, the progressive expansion of state intervention in oral health policies is observed. However, there remains a preponderance of hegemonic "dental" practices reproduced in the Unified Public Health Service (Sistema Único de Saúde - SUS and the Family Health Strategy.

    2011-04-01

    Due to the phenomenon of Taiwan'saging population has made, long-term care has become an issue of increasingly emphasized importance. According to the statistics, the family takes responsibility for most long-term care duties and more than 70% of primary family caregivers are female. In the past, because of gender-based divisions of labor and gender role expectations made, it was taken for granted that females would be the socially preferred family caregivers. Those men who devoting in themselves to such work were regarded as a rare precious. As such, family care signified entailed different life experiences for males and females. Over the years, amendments to the civil code have recognized family care contributions, and the allowance for caregivers underlines that care responsibilities have shifted away from the family to society. Traditional gender divisions of labor today are significantly more blurred; family structures have become smaller in size; female labor in the workplace has increased; and ten-year long-term care plans and long-term care insurance have been successively implemented. These transformations will make labor outsourcing more and more popular and transform family care from a private problem to a pubic policy issue. In the future, family caregivers require consideration and support on a sustained basis. It is also important to improve and monitor the quality of care services. Nurses, the major professional members of long-term care teams, should be concerned over the issue of family care while providing nursing care. They should include family caregivers in the care plan so that they can make sure that patients receive comprehensive and constant care in order to enhance the overall quality of nursing care.

    During the last decade, the ties that draw countries together both economically and environmentally have become increasingly apparent. This was clearly exposed in the recent debate over the North American Free Trade Agreement (NAFTA) and in recent decisions interpreting the General Agreement on Tariffs and Trade (GATT). Environmental aspects of other international treaties have also come under close scrutiny. This article examines the effects NAFTA and its companion, the North American Agreement on Environmental Cooperation, may have on public health and environmental regulation in border states.

    2011-03-01

    This paper appraises the public health burden of mortality in India caused by the practice of dowry and examines the association of some demographic and socio-economic factors with dowry deaths and dowry-related suicides. The paper is based on the data available on the public domains of the National Crime Records Bureau (NCRB), third National Family Health and Survey-2005-06, Planning Commission of India and Census of India 2001. In 2007, the total number of dowry deaths and dowry-related suicides reported in India were 8093 and 3148, respectively. There was a 74% increase in dowry-related deaths from1995 to 2007, while there was a 31% increase in the reporting of dowry-related suicides. Occurrence of dowry deaths has significant association with some demographic and socio-economic variables. The data reveal that the status of women is undesirable, and the burden of mortality and related morbidity is enormous. There should be a national injury surveillance system and reliable estimates of dowry-related homicides. However, available information can be used to design and implement some counter-measures to prevent dowry-related violence and deaths. The study warrants the undertaking of research to give insights into circumstances and triggers of such violence, the healthcare seeking of these victims, bottlenecks in seeking health care and reporting to the police.

  16. Rethinking the Numerate Citizen: Quantitative Literacy and Public Issues

    Directory of Open Access Journals (Sweden)

    Ander W. Erickson

    2016-07-01

    Full Text Available Does a citizen need to possess quantitative literacy in order to make responsible decisions on behalf of the public good? If so, how much is enough? This paper presents an analysis of the quantitative claims made on behalf of ballot measures in order to better delineate the role of quantitative literacy for the citizen. I argue that this role is surprisingly limited due to the contextualized nature of quantitative claims that are encountered outside of a school setting. Instead, rational dependence, or the reasoned dependence on the knowledge of others, is proposed as an educational goal that can supplement quantitative literacy and, in so doing, provide a more realistic plan for informed evaluations of quantitative claims.

    Suicide has become an international public mental health challenge, resulting in a need for interventions to address it as an individual, family, and community levels. The current scope review assesses trends regarding suicide within Latin America and the Caribbean: risk factors, protective factors, and mediators of suicidal ideation and behavior. Body: Our review is split into three sections, as a way of addressing the complex topic of suicide in an organized, comprehensive manner: (i) epidemiology of suicide in Latin America and Caribbean; (ii) factors associated to suicide ideation and attempts; and (iii) cultural factors as a predictors and mediators of suicide. Further, proper evidence about the association between suicide and cultural dimensions such as Familismo, Machismo/Marianismo, Religion and Acculturation is provided. Upon analyzing trends of and factors associated with suicide, we offer recommendations regarding future studies and intervention programs. We conclude that interventions and research should be based on and in response to cultural values and norms related to suicide within each community, in order to make more culturally-specific programs.

  1. Issues for bringing digital libraries into public use

    Science.gov (United States)

    Flater, David W.; Yesha, Yelena

    1993-01-01

    In much the same way that the field of artificial intelligence produced a cult which fervently believed that computers would soon think like human beings, the existence of electronic books has resurrected the paperless society as a utopian vision to some, an apocalyptic horror to others. In this essay we have attempted to provide realistic notions of what digital libraries are likely to become if they are a popular success. E-books are capable of subsuming most of the media we use today and have the potential for added functionality by being interactive. The environmental impact of having millions more computers will be offset to some degree, perhaps even exceeded, by the fact that televisions, stereos, VCR's, CD players, newspapers, magazines, and books will become part of the computer system or be made redundant. On the whole, large-scale use of digital libraries is likely to be a winning proposition. Whether or not this comes to pass depends on the directions taken by today's researchers and software developers. By involving the public, the effort being put into digital libraries can be leveraged into something which is big enough to make a real change for the better. If digital libraries remain the exclusive property of government, universities, and large research firms, then large parts of the world will remain without digital libraries for years to come, just as they have remained without digital phone service for far too long. If software companies try to scuttle the project by patenting crucial algorithms and using proprietary data formats, all of us will suffer. Let us reverse the errors of the past and create a truly open digital library system.

  2. CMS tracker observes muons

    CERN Multimedia

    2006-01-01

    A computer image of a cosmic ray traversing the many layers of the TEC+ silicon sensors. The first cosmic muon tracks have been observed in one of the CMS tracker endcaps. On 14 March, a sector on one of the two large tracker endcaps underwent a cosmic muon run. Since then, thousands of tracks have been recorded. These data will be used not only to study the tracking, but also to exercise various track alignment algorithms The endcap tested, called the TEC+, is under construction at RWTH Aachen in Germany. The endcaps have a modular design, with silicon strip modules mounted onto wedge-shaped carbon fibre support plates, so-called petals. Up to 28 modules are arranged in radial rings on both sides of these plates. One eighth of an endcap is populated with 18 petals and called a sector. The next major step is a test of the first sector at CMS operating conditions, with the silicon modules at a temperature below -10°C. Afterwards, the remaining seven sectors have to be integrated. In autumn 2006, TEC+ wil...

  3. The ATLAS Fast Tracker

    Volpi, Guido; The ATLAS collaboration

    2015-01-01

    The use of tracking information at the trigger level in the LHC Run II period is crucial for the trigger an data acquisition (TDAQ) system. The tracking precision is in fact important to identify specific decay products of the Higgs boson or new phenomena, a well as to distinguish the contributions coming from many contemporary collisions that occur at every bunch crossing. However, the track reconstruction is among the most demanding tasks performed by the TDAQ computing farm; in fact, full reconstruction at full Level-1 trigger accept rate (100 KHz) is not possible. In order to overcome this limitation, the ATLAS experiment is planning the installation of a specific processor: the Fast Tracker (FTK), which is aimed at achieving this goal. The FTK is a pipeline of high performance electronic, based on custom and commercial devices, which is expected to reconstruct, with high resolution, the trajectories of charged tracks with a transverse momentum above 1 GeV, using the ATLAS inner tracker information.

    The LHCb experiment is dedicated to the study of heavy flavour physics at the Large Hadron Collider (LHC). The primary goal of the experiment is to search for indirect evidence of new physics via measurements of CP violation and rare decays of beauty and charm hadrons. The LHCb detector has a large-area silicon micro-strip detector located upstream of a dipole magnet, and three tracking stations with silicon micro-strip detectors in the innermost region downstream of the magnet. These two sub-detectors form the LHCb Silicon Tracker (ST). This paper gives an overview of the performance and operation of the ST during LHC Run 1. Measurements of the observed radiation damage are shown and compared to the expectation from simulation.

    Two redundant AST-301 autonomous star trackers (AST) serve as the primary attitude sensors for JPL's space infrared telescope facility (SIRTF). These units, which employ a 1553B interface to output their attitude quaternions and uncertainty at a 2 Hz rate, provide a 1 σaccuracy of better than 0.18, 0.18, and 5.1 arcsec about their X, Y, and Z axes, respectively. This is a factor 5.5 better than the accuracy of the flight-proven AST-201 from which the trackers were derived. To obtain this improvement, the field of view (FOV) was reduced to 5 by 5 degrees, the accurate Tycho-1 and ACT catalogs were used for selecting the 71,830 guide stars, star image centroiding was improved to better than 1/50th of a pixel, and optimal attitude estimation was implemented. In addition, the apparent direction to each guide star in the FOV is compensated for proper motion, parallax, velocity aberration, and optical distortion. The AST-301 employs autonomous time-delayed integration (TDI) to achieve image motion compensation (IMC) about its X axis that prevents accuracy degradation, even at rates of 2.1 deg/s, making it actually suitable for use on spinning spacecraft. About the Y axis, a software function called "image motion accommodation" (IMA) processes smeared images to maximize the signal to noise ratio of the resulting synthetic images, which enables robust and accurate tracking at rates tested up to 0.42 deg/s. The AST-301 is capable of acquiring its attitude anywhere in the sky in less than 3 seconds with a 99.98% probability of success, without requiring any a priori attitude knowledge. Following a description of the 7.1 kg AST-301, its operation and IMA, the methodology for translating the night sky test data into performance numbers is presented, while, in addition, the results of tests used to measure alignment stability over temperature are included.

    2013-03-01

    Full Text Available BACKGROUND: Many studies and scientific evidence confirm a positive effect of physical activity on the quality of life and human health. Physical activity, which is also one of the key factors preventing mass non-communicable diseases, is decreasing in Europe, including the Czech Republic, both in children and adults. Serious health consequences for the population and economy of the countries are a reason for a discussion about including the low level of physical activity among public policy issues and a higher allocation of public sources into the area of physical activity promotion. OBJECTIVES: The main objective of the paper is to determine whether the low level of physical activity is a public policy issue. An issue that should by systematically addressed by national, regional as well as local policy. METHODS: Through the policy analysis approach we conducted a content analysis of 25 systematically selected foreign national strategies aimed at the issue of physical activity promotion. The data source was an internal database of the World Health Organization - the International Inventory of Documents on Physical Activity Promotion. The content analysis of the strategies was performed using the Atlas.ti software tool. RESULTS: During a content analysis of 25 foreign strategies a total of 411 text segments (quotations relating to the low level of physical activity were selected. These text segments showed five basic features of a public policy issue according to a conceptual framework developed by Bardach (2000 and Patton and Sawicky (1993 - 1 affects the lives of a significant number of people of a society; 2 is analysable; 3 can be solved through public policy tools; 4 the primary cause or problem can be defined; 5 cannot be solved easily and quickly. CONCLUSIONS: The results indicate that the low level of physical activity is a public policy issue that must be systematically addressed at national level.

    Full Text Available European Communication Monitor is the largest longitudinal research project in public relations practice in the world. Data collected annually from 2007 to 2014 show that practitioners perceive five issues as the most important for their work: linking business strategy and communication, coping with the digital evolution and social web, building and maintaining trust, dealing with the demand for more transparency and active audiences, and dealing with the speed and volume of information flow. Perception of the importance of various issues for the practice of public relations is largely dependent on the gender, geography (division between Northern and Western vs. Southern and Eastern Europe, and sector in which a practitioner works (corporate, government, NGO or agency. While gender and sectorial differences studied in academic public relations literature, divisions in public relations practice between North-Western and South-Eastern Europe are largely ignored.

    2014-01-01

    Schools of nursing are challenged to find clinical placements in public health settings. Use of simulation can address situations unique to public health, with attention to specific concerns, such as environmental health. Environmental health is an integral part of public health nursing and is a standard of professional practice. Current simulations focus on acute care situations, offering limited scenarios with a public health perspective and excluding environmental health. This study's simulation scenario was created to enhance nursing students' understanding of public health concepts within an environmental health context. Outcomes from the simulation include the need for integration of environmental issues in public health teaching. Students stated that this scenario provided a broader understanding of the environmental influences that can affect the client's and family's health. This scenario fills a void in simulation content, while providing an interactive teaching and learning strategy to help students to apply knowledge to practice. Copyright 2014, SLACK Incorporated.

  15. Identifying the science and technology dimensions of emerging public policy issues through horizon scanning.

    Full Text Available Public policy requires public support, which in turn implies a need to enable the public not just to understand policy but also to be engaged in its development. Where complex science and technology issues are involved in policy making, this takes time, so it is important to identify emerging issues of this type and prepare engagement plans. In our horizon scanning exercise, we used a modified Delphi technique. A wide group of people with interests in the science and policy interface (drawn from policy makers, policy adviser, practitioners, the private sector and academics elicited a long list of emergent policy issues in which science and technology would feature strongly and which would also necessitate public engagement as policies are developed. This was then refined to a short list of top priorities for policy makers. Thirty issues were identified within broad areas of business and technology; energy and environment; government, politics and education; health, healthcare, population and aging; information, communication, infrastructure and transport; and public safety and national security.

    Are the policies designed by decision-makers differing from society's wishes and preferences. The present paper analyzes the divergences between forest policy and public opinion in the Region of Valencia (Comunidad Valenciana) in Eastern Spain. The data is based on an extensive telephone survey of the general public on their perception of forestry issues. The issues studied include attitudes regarding forest fires, silvicultural treatments, the externalise produced by forest owners, and the state forest services role related to these issues. In total, the answers of 823 respondents were analyzed using classification trees. The results of the analysis showed a large divergence between the desires, preferences and priorities of society, on the one hand, and the policies implemented by the regional government, on the other. The study concludes that communication strategies concerning sustainable forest management need to be further developed by the responsible authorities, with the input of the research community.

    2013-01-01

    Full Text Available The framework provided by the Millennium Development Goals includes maternal health as an area of priority. Postnatal depression (PND is a serious public health issue because it occurs at a crucial time in a mothers’ life, can persist for long periods, and can have adverse effects on partners and the emotional, behavioural, and cognitive development of infants and children. Internationally, public health nurses (PHNs are key professionals in the delivery of health care to mothers in the postpartum period, and international research collaborations are encouraged. Two researchers from the European Academy of Nursing Science (EANS identified a need to collaborate and strengthen research capacity and discussion on postnatal depression, a public health nursing issue in both countries. Within the context of public health and public health nursing in Ireland and Norway, the aim of this paper is to present a discussion on the concept of PND, prevalence, and outcomes; screening issues for PHNs; and the research evidence of the benefits of social support in facilitating recovery for new mothers.

    2013-01-01

    The Hyperspectral Imager-Tracker (HIT) is a technique for visualization and tracking of low-contrast, fast-moving objects. The HIT architecture is based on an innovative and only recently developed concept in imaging optics. This innovative architecture will give the Light Prescriptions Innovators (LPI) HIT the possibility of simultaneously collecting the spectral band images (hyperspectral cube), IR images, and to operate with high-light-gathering power and high magnification for multiple fast- moving objects. Adaptive Spectral Filtering algorithms will efficiently increase the contrast of low-contrast scenes. The most hazardous parts of a space mission are the first stage of a launch and the last 10 kilometers of the landing trajectory. In general, a close watch on spacecraft operation is required at distances up to 70 km. Tracking at such distances is usually associated with the use of radar, but its milliradian angular resolution translates to 100- m spatial resolution at 70-km distance. With sufficient power, radar can track a spacecraft as a whole object, but will not provide detail in the case of an accident, particularly for small debris in the onemeter range, which can only be achieved optically. It will be important to track the debris, which could disintegrate further into more debris, all the way to the ground. Such fragmentation could cause ballistic predictions, based on observations using high-resolution but narrow-field optics for only the first few seconds of the event, to be inaccurate. No optical imager architecture exists to satisfy NASA requirements. The HIT was developed for space vehicle tracking, in-flight inspection, and in the case of an accident, a detailed recording of the event. The system is a combination of five subsystems: (1) a roving fovea telescope with a wide 30 field of regard; (2) narrow, high-resolution fovea field optics; (3) a Coude optics system for telescope output beam stabilization; (4) a hyperspectral

Besides high precision mounting, survey measurements and the Laser Alignment System, track-based alignment is needed to reach the envisaged precision.\\\\ Three different algorithms for track-based alignment were successfully tested on a sample of cosmic-ray data collected at the Tracker Integration Facility, where 15\\% of the Tracker was tested. These results, together with those coming from the CMS global run, will provide the basis for the full-scale alignment of the Tracker, which will be carried out with the first \\emph{p-p} collisions.

  17. Public healthcare in Mozambique: strategic issues in the ICT development during managerial changes and public reforms.

    Piotti, B; Macome, E

    2007-06-01

    It has been predicted that major introduction of information communication technology (ICT) for health care organisations (HCO) over the next 10 years will be used to achieve the universal coverage and improve the quality of health care delivered to people. Which is the best strategy on ICT transfer, adoption and adaptation for the local Mozambican HCO? This paper argues that a sociotechnical approach of ICT development can help policy makers and health managers to address the technology transfer in a better and more appropriate way to their social context and to the public health reforms in progress. The urgency of health care demands (e.g. AIDS epidemic) and the institutional changes implemented by the Government and the local Ministry of Health (MOH), open a dynamic process of re-organisation inside the health institutions in the next years. This process needs to be monitored and initiatives planned, which places pressure on the evolution of health information system (HIS). The increase in the use of ICT can be an ally for health managers. The emergence of the open source software (OSS) and the recent ICT market trends towards networking may also enable local HCO to better face and solve the long process of health care standardisation, which usually prepares and accompanies any introduction of ICT. On the other side, the "big bang" introduction of electronic packages, devices and software applications may be an obstacle framing and anchoring local HCO to external settings, "modern" and universal models. Thus, a uniform step-by-step implementation of hospital-based health information system is desirable.

  18. The educated citizen and global public health issues: One model for integration into the undergraduate curriculum

    Directory of Open Access Journals (Sweden)

    Rosemary M. Caron

    2016-03-01

    Full Text Available The Educated Citizen Initiative proposes that an understanding of public health issues is a core component of an educated citizenry and is essential to developing one’s societal responsibility. This initiative supports the Institute of Medicine’s recommendation that all undergraduates should have access to education in public health. Furthermore, the Liberal Education and America’s Promise (LEAP framework developed by the Association of American Colleges and Universities supports the integration of public health education into general and liberal education with an aim to produce an educated citizenry. The LEAP framework is implemented by teaching about the role of social determinants in a population’s health status; the significance of personal and social responsibility; and providing skills for inquiry, critical thinking, problem solving, and evaluation. This article describes one university’s experience in generating an educated citizenry cognizant of comprehensive public health conflicts, thus contributing to both a local and global perspective on learning.

  19. [Specialist and lay ethical expertise in public health: issues and challenges for discourse ethics].

    Science.gov (United States)

    Massé, Raymond

    2012-01-01

    In recent decades, both public health professionals and the populations targeted by prevention and health promotion programs have shown an increasing interest in ethical issues since some interventions have been seen as impinging on fundamental rights and values. Insofar as bioethics is not adapted to population interventions and community health issues, a specific expertise in public health ethics is now required. However, ethical expertise in this area faces many challenges. The purpose of this paper is to examine four of these challenges. The first three challenges concern professional or specialist expertise. The paper suggests that expertise in public health ethics should go beyond the search for greater sophistication in defining ethical principles. Experts in public health ethics also need to identify appropriate strategies to include public health professionals in ethical analysis and to adopt a critical and reflexive approach to the status of moral experts and moral expertise. However, the main challenge is to identify appropriate ways of reconciling lay and specialist ethical expertise. The paper argues that secular morality and common morality represent two key sources of lay ethics expertise and that the fundamental values that inform discourse ethics should be derived from both forms of expertise.

    This document summarizes past achievements, current activities and future goals of the R&D program aimed at the design, prototyping and characterization of a full detector module, equipped with monolithic pixel sensors, matching the requirements for the Vertex Tracker at the ILC. We provide a plan of activities to obtain a demonstrator multi-layered vertex tracker equipped with sensors matching the ILC requirements and realistic lightweight ladders in FY11, under the assumption that ILC detector proto-collaborations will be choosing technologies and designs for the Vertex Tracker by that time. The R&D program discussed here started at LBNL in 2004, supported by a Laboratory Directed R&D (LDRD) grant and by funding allocated from the core budget of the LBNL Physics Division and from the Department of Physics at UC Berkeley. Subsequently additional funding has been awarded under the NSF-DOE LCRD program and also personnel have become available through collaborative research with other groups. The aim of the R&D program carried out by our collaboration is to provide a well-integrated, inclusive research effort starting from physics requirements for the ILC Vertex Tracker and addressing Si sensor design and characterization, engineered ladder design, module system issues, tracking and vertex performances and beam test validation. The broad scope of this program is made possible by important synergies with existing know-how and concurrent programs both at LBNL and at the other collaborating institutions. In particular, significant overlaps with LHC detector design, SLHC R&D as well as prototyping for the STAR upgrade have been exploited to optimize the cost per deliverable of our program. This activity is carried out as a collaborative effort together with Accelerator and Fusion Research, the Engineering and the Nuclear Science Divisions at LBNL, INFN and the Department of Physics in Padova, Italy, INFN and the Department of Physics in Torino, Italy and the Department

    2011-09-01

    Full Text Available Environmental problems are very serious and complex to be resolved through science approach, technical and legislation solely. Hence, the inclucive and active involvement and participation of civil is wanted. Civil society is inter parties interested and sure they involved directly with every planned development project and practiced at area they. Earlier study has proven that public societal involvement in environmental issue is still low and minimum. The study conducted in Jajahan Kuala Krai, Kelantan is intended to find out how far population knowledge in study area on environmental issues and the level of involvement the in said issue. This study involved 174 respondents. The study between demographic factor with respondent knowledge in environmental issues shows that is a significant relationship between respondent income and education with value of p respectively 0.039 and 0.036. The association between demographic factor with respondent's knowledge in local environmental issue on the other hand shows that there are significant relationship between gender, age, income, education and resident period with the value of p respectively 0.045, 0.000, 0.029, 0.046 and 0.000. For demographic factor in association with environmental issues, has shown that there is a significant relationship between age, income, education and resident period with the value of p respectively 0.036, 0.041, 0.001 and 0.001. The results that found respondent income factor and education did influence on respondents knowledge level and involvement in environmental issues. As a conclusion, an actively engaged society in related environmental issues is very important due to the assurance of environmental quality that always will be protected.

    2009-01-01

    There are recognized needs for cross-training health professionals in human, animal, and ecosystem health and for public health policy to be informed by experts from medical, science, and social science disciplines. Faculty members of the Community Health and Preventive Medicine Section at the University of Illinois at Urbana-Champaign, College of Veterinary Medicine, and the Institute of Government and Public Affairs, University of Illinois at Urbana-Champaign, have offered a public-policy course designed to meet those needs. The course was designed as a practicum to teach students the policy-making process through the development of policy proposals and to instruct students on how to effectively present accurate scientific, demographic, and statistical information to policy makers and to the public. All students substantially met the learning objectives of the course. This course represents another model that can be implemented to help students learn about complex, multifactorial issues that affect the health of humans, animals, and ecosystems, while promoting participation in public health policy development.

  9. Public information on radioactive waste: a study of an emerging issue

    Energy Technology Data Exchange (ETDEWEB)

    Bronfman, L.M.; Bronfman, B.H.; Regens, J.L.

    1979-10-01

    Through an analysis of information provided in the printed media on the topic of radioactive waste, the study analyzes the emergence of radioactive waste as a public issue in the press. Over eight hundred articles printed in both specialized and non-specialized sources from 1973 to 1978 have been content-analyzed in order to describe how the problem of radioactive waste is defined and what dimensions of the problems are receiving attention. Between 1973 and 1978, there was a substantial increase in the amount of information on the topic of radioactive waste available to the public through a variety of popular and specialized media sources. This increase coincides with documented public concern with the problem of radioactive waste. Discussions of radioactive waste have focused for all sources more frequently on themes not directly related to the technical problems of radioactive waste storage or isolation. A substantial amount of the information available to a variety of segments of the public is composed of discussions of real or perceived risk related to the existence of waste or to methods of disposing of it. In addition to risk, a substantial proportion of the discussions deal with institutional themes. Over time, the total amount of information on most dimensions of the radioactive waste problem has increased substantially. Institutional themes have gained relative to other issues over the three time periods. National and local press sources infrequently specify the form of waste being discussed thus providing evidence that the quality of technical information available to some members of the public is very low.

  10. Scholarly Electronic Full-Text Publications via the Internet: Issues and Impacts

    Science.gov (United States)

    Kosmin, Linda J.

    1999-01-01

    On-line access to complete texts of scholarly journal articles, conference papers, and books is facilitated by rapidly developing World-wide Web Internet access and capabilities. Meanwhile, print publications continue to be produced and read in spite of the proliferation of many networked electronic publications. The purpose of this presentation is to highlight fundamental issues impacting stakeholder groups, as the trend continues towards migration from paper to affordable ubiquitous networked full-text publications. Librarians, publishers, authors and end-users have various viewpoints, interests, and concerns. There are many issues challenging all stakeholder groups. For instance, all share concerns about administering copyright compliance and enforcing fair use. Uncontrollable electronic downstreaming could result in infringed copyright, while limiting a publisher's entitled revenue stream. Moreover, metered fee-based access may hamper scholarly information research. And, self-authoring on the Internet without peer filtering could lead to information clutter. Many related issues challenge librarians in particular. Among these are rising journal subscription prices, regardless if offered in print or electronic. Some electronic offerings are independent of print, others supplement or duplicate print; several publishers presently require subscribing to print in order to access electronic. Furthermore, numbers of publications are n'ow being marketed via the Internet directly to end-users, which can be viewed as encouraging users to bypass the traditional library. A key issue challenging publishers today is the rapidly expanding electronic user base that is demanding delivery of added-value full-text to desktop computers. Also of growing concern appears to be the decline in print sales to libraries, thereby reducing traditional revenue stream potential. Nowadays, publishers are more hesitant about investing in the production of publications geared toward small niche

  11. Semiconductor Strip Tracker Endcaps come to CERN

    CERN Multimedia

    P. Bell

    The first few months of 2006 saw the delivery to CERN of the final components of the ATLAS Semi-Conductor Tracker (SCT), namely the completed SCT end-caps. Regular ATLAS eNews readers will recall that the SCT barrel arrived in sections in 2005 and was assembled later that year (see the April 2005 and December 2005 issues, respectively.) And as reported in this issue of the eNews, the barrel SCT has recently been integrated with the barrel Transition Radiation Tracker. The end-caps were constructed in Liverpool (side C) and NIKHEF (side A), using components manufactured at many different sites across the world. End-cap C left Liverpool on Monday 20 February and arrived at CERN after a two-day journey by road and through the Channel Tunnel. Accelerations in all three dimensions were monitored during the trip, as was temperature and humidity inside the container; all values remained within pre-specified safe ranges. The end-cap was visually inspected upon arrival, with no obvious damage being seen. Subsequent ...

  12. Ethical Considerations for Psychologists Taking a Public Stance on Controversial Issues: The Balance Between Personal and Professional Life.

    Science.gov (United States)

    Haeny, Angela M

    2014-07-01

    Previous literature has documented the general issues psychologists often face while balancing their personal and professional lives. The struggle stems from attempting to satisfy the need to maintain a life outside of work while having the professional obligation to follow the American Psychological Association's (APA's) Ethical Principles of Psychologists and Code of Conduct (Ethics Code) to prevent their personal lives from interfering with their professional roles and relationships. The present paper analyzes the subject of psychologists taking a public position on controversial public issues. Although the APA Ethics Code does not restrict how psychologists conduct themselves during their personal time, taking a public stance on a controversial issue could potentially strain professional relationships and inadvertently reflect negatively on the profession. The present paper examines ethical issues that a) should be taken into account before psychologists take a public position on a controversial issue, and b) are in conflict with APA's Ethics Code or current research.

    2012-06-01

    In the study described in this article, the authors investigated the perceptions and needs of public health inspectors (PHIs) in the province of Ontario, Canada, with regard to food safety issues and information resources. A cross-sectional online survey of 239 Ontario PHIs was conducted between April and June 2009. Questions pertained to their perceptions of key food safety issues and foodborne pathogens, knowledge confidence, available resources, and resource needs. All respondents rated time-temperature abuse, inadequate hand washing, and cross contamination as important food safety issues. Salmonella, Campylobacter, and E. coli O157:H7 were pathogens reported to be of concern to 95% of respondents (221/233). Most respondents indicated that they were confident in their knowledge of food safety issues and foodborne pathogens, but wanted a central, online resource for food safety information and ongoing food safety education training for PHIs. The data from the authors' study can be used in the development of information resources targeted to the needs of PHIs involved in food safety.

  15. Partnership Versus Public Ownership of Accounting Firms: Exploring RelativePerformance, Performance Measurement and Measurement Issues

    Directory of Open Access Journals (Sweden)

    Mark E Pickering

    2012-09-01

    Full Text Available Despite theoretical arguments that partnerships are the most efficient ownership form for professional service firms (PSFs, PSFs are increasingly moving to other ownership structures, such as publicly listed companies (PLCs. Research on the comparative performance of PSF, PLCs and partnerships is sparse with conflicting results suggesting that some segments of PSFs are moving to a less efficient form. This study explores the performance of two Australian accounting PLCs compared to a sample of similar sized mid tier accounting firms. The accounting PLCs achieved substantially higher revenue growth rates but lower productivity than the partnership sample. Measurement issues were identified in the use of closing resource numbers and different treatment of reporting merger and acquisition revenues which may partially explain the underperformance of publicly owned PSFs in prior studies. The need for research at a more detailed level exploring the market and service focus, organisational structures, resources utilised and resource costs across different PSF ownership forms is suggested.

  16. A NEW PUBLIC HEALTH ISSUE: CONTAMINATION WITH ARSENIC OF PRIVATE WATER SOURCES

    Directory of Open Access Journals (Sweden)

    ANCA ELENA GURZAU

    2012-03-01

    Full Text Available A new public health issue: contamination with arsenic of private water sources. Known since the early ‘40s, the natural contamination with arsenic of depth water in Bihor and Arad areas continues to incite interest, especially since the rural localities still use depth water as the main source of drinking water. Arsenic concentrations measured in the water sources in the area range between 0-176 μg/L, and it is estimated that over 45,000 people are exposed via drinking water to arsenic concentrations above 10 μg/L. The present study proposed the measurement of arsenic concentrations from old public sources and individual private water sources from recent wells located in five localities in Arad County, samples being collected during 2010-2011. The results showed that public water sources declared or not non-potable contain arsenic above the maximum allowable concentration of 10 μg/L. Individual water sources recently drilled as an alternative for the population to the lack of access to safe water from public water systems, presented high concentrations of arsenic in most cases, even higher than the concentrations of the public sources declared by authorities as non-potable. In the absence of informing and counseling the population regarding the natural uneven distribution of arsenic in the depth water and its potential carcinogenicity, human exposure continues and it is even more intense. The significance of the problem in terms of public health becomes even more important as for the private water sources quality is not monitored by the authorities according to law, water analysis being performed on request and for a fee.

    2014-03-01

    Lay involvement in public health programmes occurs through formalised lay health worker (LHW) and other volunteer roles. Whether such participation should be supported, or indeed rewarded, by payment is a critical question. With reference to policy in England, UK, this paper argues how framing citizen involvement in health only as time freely given does not account for the complexities of practice, nor intrinsic motivations. The paper reports results on payment drawn from a study of approaches to support lay people in public health roles, conducted in England, 2007-9. The first phase of the study comprised a scoping review of 224 publications, three public hearings and a register of projects. Findings revealed the diversity of approaches to payment, but also the contested nature of the topic. The second phase investigated programme support matters in five case studies of public health projects, which were selected primarily to reflect role types. All five projects involved volunteers, with two utilising forms of payment to support engagement. Interviews were conducted with a sample of project staff, LHWs (paid and unpaid), external partners and service users. Drawing on both lay and professional perspectives, the paper explores how payment relates to social context as well as various motivations for giving, receiving or declining financial support. The findings show that personal costs are not always absorbed, and that there is a potential conflict between financial support, whether sessional payment or expenses, and welfare benefits. In identifying some of the advantages and disadvantages of payment, the paper highlights the complexity of an issue often addressed only superficially. It concludes that, in order to support citizen involvement, fairness and value should be considered alongside pragmatic matters of programme management; however policy conflicts need to be resolved to ensure that employment and welfare rights are maintained.

  20. The Human Behavioral Ecology of Contemporary World Issues : Applications to Public Policy and International Development.

    Science.gov (United States)

    Tucker, Bram; Rende Taylor, Lisa

    2007-09-01

    Human behavioral ecology (HBE) began as an attempt to explain human economic, reproductive, and social behavior using neodarwinian theory in concert with theory from ecology and economics, and ethnographic methods. HBE has addressed subsistence decision-making, cooperation, life history trade-offs, parental investment, mate choice, and marriage strategies among hunter-gatherers, herders, peasants, and wage earners in rural and urban settings throughout the world. Despite our rich insights into human behavior, HBE has very rarely been used as a tool to help the people with whom we work. This article introduces a special issue of Human Nature which explores the application of HBE to significant world issues through the design and critique of public policy and international development projects. The articles by Tucker, Shenk, Leonetti et al., and Neil were presented at the 104th annual meeting of the American Anthropological Association (AAA) in Washington, D.C., in December 2005, in the first organized session of the nascent Evolutionary Anthropology Section (EAS). We conclude this introduction by summarizing some theoretical challenges to applying HBE, and ways in which evolutionary anthropologists can contribute to solving tough world issues.

    The LHCb detector will be upgraded during the Long Shutdown 2 (LS2) of the LHC in order to cope with higher instantaneous luminosities and to read out the data at 40 MHz using a trigger-less read-out system. All front-end electronics will be replaced and several sub-detectors must be redesigned to cope with higher occupancy. The current tracking detectors downstream of the LHCb dipole magnet will be replaced by the Scintillating Fibre (SciFi) Tracker. The SciFi Tracker will use scintillating fibres read out by Silicon Photomultipliers (SiPMs). State-of-the-art multi-channel SiPM arrays are being developed to read out the fibres and a custom ASIC will be used to digitise the signals from the SiPMs. The evolution of the design since the Technical Design Report in 2014 and the latest R & D results are presented.

Most common scenes are four two inches thick step wedges of different dimensions: 12-inch x 12-inch, 12-inch x 9-inch, 12-inch x 6-inch, and 12-inch x 3-inch; and a one three inches thick hemisphere of lead with spherical hollow, and a similar full lead sphere.

  4. Applying behavioural science to issues of public health in South Africa: The case for social norms intervention

    Directory of Open Access Journals (Sweden)

    Gary Ganz

    2017-05-01

    Full Text Available In the effort to address behavioural risk factors - which contribute significantly to the global burden of disease there is a growing movement in public health towards the use of interventions informed by behavioural science. These interventions have the benefit of being amenable to testing in randomised controlled trials, are cost-effective and, when scaled up, can have significant public health benefits. A subset of these interventions attempts to change behaviour by shifting social norms perception (what I think everyone else does and thinks. We surveyed the work on social norms intervention and considered its applicability to issues of public health in South Africa. Social norms interventions have widespread and significant potential to address issues of public health in South Africa; policymakers should look to these interventions as cost-effective tools to address key issues. More broadly, we advocate for an expansion of the use of behavioural science in developing public policy in South Africa.

    2012-01-01

    Social neuroscience and its potential implications create an interesting case study for examining human research ethics policies on the topic of public communication of research. We reviewed mainstream national and international human research ethics guidelines and policies on issues of public communication of research. Our analysis relied on five thematic nets to capture the interactions between research and the public: public understanding, knowledge translation, public participation, social outcomes, and dual use. Coverage of these topics is sparse and inconsistent in mainstream policies and guidelines. We identify three options to address these gaps and analyze their strengths and weaknesses.

    2016-08-01

    Full Text Available In this article, we present analyses from a researcher-practitioner partnership in the District of Columbia Public Schools, where we are exploring the impact of educational software on students’ academic achievement. We analyze a unique data set that combines student-level information from the district with data of student usage of a mathematics game platform: First in Math (FIM. These data offer a window into long-standing issues in the educational technology literature around implementation, equity, and student achievement. We show that time spent in FIM was correlated with improved future performance on standardized math assessments for students in Grades 4–8. However, student time spent using FIM was highly related to factors such as race, gender, and prior achievement. Such observations from data are helpful for school districts and researchers to inform equitable implementation of new technologies and maximize benefits to learners.

  11. Issues in public health: assuaging concern from contaminated land resulting from land use dynamics in Malaysia.

    Singh, H

    2001-01-01

    The anthropogenic disturbance of pristine natural areas caused by land use and transformation from one use to another as a result of increased pressure from demographic changes and the economics of this shrinking resource can result in adverse health hazards for the community. This paper appraises the consequential impact of land use dynamics, its assessment and measures required to assuage this overlooked public health issue. The anthropogenic impact from land use in Malaysia from the industrial sector alone points toward the potential capacity to cause adverse health hazards. A deficiency in assessing this impact due to limited information has resulted in the inability to establish the extent of this problem. Several necessary measures to establish the extent of the problem involving ways to characterise contaminated land and the evolution of a strategy to resolve it are discussed.

    GigaTracker, the NA62’s upstream spectrometer, plays a key role in the kinematically constrained background suppression for the study of the K + ! p + n ̄ n decay. It is made of three independent stations, each of which is a six by three cm 2 hybrid silicon pixels detector. To meet the NA62 physics goals, GigaTracker has to address challenging requirements. The hit time resolution must be better than 200 ps while keeping the total thickness of the sensor to less than 0.5 mm silicon equivalent.

  14. In Defense of Sparse Tracking: Circulant Sparse Tracker

    KAUST Repository

    Zhang, Tianzhu

    2016-12-13

    Sparse representation has been introduced to visual tracking by finding the best target candidate with minimal reconstruction error within the particle filter framework. However, most sparse representation based trackers have high computational cost, less than promising tracking performance, and limited feature representation. To deal with the above issues, we propose a novel circulant sparse tracker (CST), which exploits circulant target templates. Because of the circulant structure property, CST has the following advantages: (1) It can refine and reduce particles using circular shifts of target templates. (2) The optimization can be efficiently solved entirely in the Fourier domain. (3) High dimensional features can be embedded into CST to significantly improve tracking performance without sacrificing much computation time. Both qualitative and quantitative evaluations on challenging benchmark sequences demonstrate that CST performs better than all other sparse trackers and favorably against state-of-the-art methods.

    Full Text Available Because of its magnitude and changing dynamics, the Ebola epidemics currently affecting some West African countries constitutes one of the most serious public health problems in recent decades. Conceptualised as a case study with two levels of analysis, this article aims at analysing the response to the Ebola epidemics in Guinea in order to ultimately highlight the public health organisational issues related to this response and to propose some possible solutions to improve the efficiency of this response. This article is based on documentary analysis, observation and a three month participating immersion conducted in Guinea from June 2014 to August 2014. Using certain elements of Parsons’ social action theory, this study has shown the existence of 4 systems of social intervention in the organisation and management of the response to the Ebola epidemics in Guinea. They are the WHO, MSF, the Red Cross and the Ministry of Health. Each of these systems of social intervention has specific characteristics and specificities and interacts actively at several levels of the healthsystem of Guinea. Having completed the analysis of the interventions undertaken by these 4 systems of social action, and using the conceptual basis of the complexity theory, we propose some avenues for reflection and action for improving the quality of the response to the Ebola epidemics in Guinea, in order to finally restrain and stop its propagation in other African countries and other continents.

  18. 3D Part-Based Sparse Tracker with Automatic Synchronization and Registration

    KAUST Repository

    Bibi, Adel Aamer

    2016-12-13

    In this paper, we present a part-based sparse tracker in a particle filter framework where both the motion and appearance model are formulated in 3D. The motion model is adaptive and directed according to a simple yet powerful occlusion handling paradigm, which is intrinsically fused in the motion model. Also, since 3D trackers are sensitive to synchronization and registration noise in the RGB and depth streams, we propose automated methods to solve these two issues. Extensive experiments are conducted on a popular RGBD tracking benchmark, which demonstrate that our tracker can achieve superior results, outperforming many other recent and state-of-the-art RGBD trackers.

    Communication regarding the management of radioactive materials is a well-established challenge. Residents and consumers have suspected for years that companies and governments place short-term economic concerns ahead of health and safety. This skepticism is compounded with increased attention to safety issues at nuclear power plants everywhere after Fukushima. Nonetheless, today's environment presents unexpected opportunities to transform public fear into teachable moments that bring knowledge and facts to discussions on nuclear energy. In the weeks following Japan's crisis, the lack of reliable information on radiation levels saw citizens taking to the streets with dosimeters and Geiger counters in crowd-sourced radiation monitoring efforts. Efforts, based mainly online, represent a growing set of examples of how internet and cell-phone technology are being put to use in emergency situations. The maps, graphs and tables created to meet public interest also exemplify some of the psychological priorities of audiences and present learning tools that can improve future education efforts in non-emergency situations. Industry outreach efforts often consist of technical details and quantitative data that are difficult for lay audiences to interpret. The intense attention to nuclear energy issues since last March has produced a wide array of visual samples. Citizen monitors, news organizations, government agencies and others have displayed quantitative information in innovative ways. Their efforts offer new perspective on what charts, maps and info graphics do - or need to do - to illustrate requirements, record assessments and promote understanding of nuclear-waste issues. Surveying the best examples, nuclear communicators can improve their offerings of easy-to-use, evidence-based visuals to inform stakeholders. Familiar to most communications professionals in the nuclear industry, risk communication is a science-based approach with over three decades of

    Full text of publication follows: AIN (Associazione Italiana Nucleare or Italian Nuclear Association) is a non-profit organization that includes a wide range of competence and expertise in the field of nuclear science and technology in Italy. A leading role among AIN members is now covered by SOGIN a company mainly involved in waste treatment and conditioning together with dismantling of the Italian nuclear power plants and installations. The same company detains most of the national competences on Nuclear Power Plants operation and safety that have allowed to provide services to a number of domestic and international clients. Radioactive waste management is a major issue for the acceptability of nuclear power energy and nuclear technologies in general. A solution to the disposal of nuclear waste from the past operation of four NPP and of the Fuel Cycle Facilities together with all the other nuclear waste from hospitals, medical facilities, industries and research centres is today essential. A nuclear-waste storage facilities located in one secured place is a national priority, given the increased risks of possible terrorist attacks, accidents or natural disasters. The Italian decision needs to follow the guidelines and paths decided at the international and European level without delegating to future generations the problems and waste connected to previous use of nuclear technologies. This issue needs to be addressed and solved before starting any discussion on nuclear power in Italy as the recent case of the strong opposition against the site proposed by the Italian Government demonstrates. The site that was selected by the Italian Government is Scanzano Jonico (Matera province in the Basilicata region). The decision is based on a study by SOGIN in cooperation with other institutions such as ENEA and Italian universities, and considering a previous work of the National Geological Service. The study follows the guidelines of ONU-IAEA and the solutions adopted at

    Utilizing the capabilities of digital planetariums, the Denver Museum of Nature & Science, the California Academy of Sciences, NOVA/WGBH, The Elumenati, and affiliates of the National Oceanic & Atmospheric Administration formed the Worldviews Network. The network's mission is to place Earth in its cosmic context to encourage participants to explore connections between social & ecological issues in their backyards. Worldviews launched with informal science institution partners: the American Museum of Natural History, the Perot Museum of Nature & Science, the Journey Museum, the Bell Museum of Natural History, the University of Michigan Natural History Museum, and the National Environmental Modeling & Analysis Center. Worldviews uses immersive visualization technology to engage public audiences on issues of global environmental change at a bioregional level. An immersive planetarium show and dialogue deepens public engagement and awareness of complex human-natural system interactions. People have altered the global climate system. Our communities are increasingly vulnerable to extreme weather events. Land use decisions that people make every day put both human lives and biodiversity at risk through direct and indirect effects. The Worldviews programs demonstrate the complex linkages between Earth's physical and biological systems and their relationship to human health, agriculture, infrastructure, water resources, and energy. We have focused on critical thresholds, such as freshwater use, biodiversity loss, land use change, and anthropogenic changes to the nitrogen and phosphorus cycles. We have been guided by environmental literacy principles to help our audiences understand that humans drive current trends in coupled human-natural systems--and that humans could choose to play an important role in reversing these trends. Museum and planetarium staff members join the Worldviews Network team and external advisers to produce programs that span cosmic, global, and

    Genetically Modified Organisms (GMOs) are a fact of modern agriculture and a major field of discussion in biotechnology. As science incessantly achieves innovative and unexpected breakthroughs, new medical, political, ethical and religious debates arise over the production and consumption of transgenic organisms. Despite no described medical condition being directly associated with a diet including approved GM crops in large exposed populations such as 300,000,000 Americans and a billion Chinese, public opinion seems to look at this new technology with either growing concern or even disapproval. It is generally recognized that a high level of vigilance is necessary and highly desirable, but it should also be considered that GMOs are a promising new challenge for the III Millennium societies, with remarkable impact on many disciplines and fields related to biotechnology. To acquire a basic knowledge on GMO production, GM-food consumption, GMO interaction with humans and environment is of primary importance for risk assessment. It requires availability of clear data and results from rigorous experiments. This review will focus on public health risks related with a GMO-containing diet. The objective is to summarize state of the art research, provide fundamental technical information, point out problems and perspectives, and make available essential tools for further research. Are GMO based industries and GMO-derived foods safe to human health? Can we consider both social, ethical and public health issues by means of a constant and effective monitoring of the food chain and by a clear, informative labeling of the products? Which are the so far characterized or alleged hazards of GMOs? And, most importantly, are these hazards actual, potential or merely contrived? Several questions remain open; answers and solutions belong to science, to politics and to the personal opinion of each social subject.

  4. Sport for Development and Global Public Health Issues: A Case Study of National Sports Associations

    2017-05-01

    Full Text Available Sport is widely recognised for the contribution it can make to international development goals. More specifically, the value of sport as a tool for development gained its impetus through the HIV/AIDS pandemic in sub-Saharan Africa. The institutionalized relationship between sport and development has mainly focussed on sport-for-development (SfD non-governmental organisations (NGOs. This study proposed to examine the response of National Sports Associations (NSAs towards the multisectoral approach for HIV/AIDS prevention in Zambia. The study draws on lessons learnt from how NSAs within a resource-scarce or low-income country responded to a health pandemic. While public health was previously a state and health sector preserve, the impact of HIV/AIDS pandemic influenced not only the way that a pandemic is managed but also other public health issues. A case study approach was adopted comprising of three National Sports Associations (NSAs as units of analysis. The study utilised semi-structured interviews, documentary analysis and field observations to gain perspectives on how each NSA mainstreamed and implemented work-based health programmes. Using governance and policy network theories, the paper discusses each NSAs’ role in the governance and implementation of a multisectoral approach to a health pandemic. The findings identified lack of engagement of sports agencies at strategic decision-making level, marginalisation of sport by other sectors, and variations in implementation patterns among sports agencies. Further findings indicate that lack of resources among government sport agencies or departments limited their involvement with other state or non-state actors in strategic level meetings or health policy networks. Resource-scarce conditions placed limitations on the political steer of state actors while non-state actors with foreign resources attracted collaboration from other public health policy networks.

    Generating awareness of environmental conservation issues among the public is essential if there is an expectation of them to alter their behaviour, facilitate informed decisions and engage governments or regulatory authorities to take action. There are, however, exceedingly few public engagement success stories related to inland fishes and fisheries policy and resource allocation decisions. Inland aquatic resources and their associated fisheries provide employment, recreation, culture and, in developing regions, a considerable proportion of human nutrition and food security. Freshwater fishes are incredibly diverse but are among the most endangered organisms globally. Many threats to inland fisheries are driven largely by externalities to inland fisheries. The purpose of this paper is to draw attention to the role and plight of inland fishes and fisheries, and the need to generate the public and political will necessary to promote meaningful conservation. With this paper, the extent to which the scientific and environmental management communities have failed to engage the public in issues related to inland fishes and fisheries is characterized. Next, the barriers or factors that serve as the basis for the problem with public engagement are identified. The paper concludes by identifying strategies, including those focused on environmental education initiatives, for building the public and political will necessary to promote meaningful conservation of inland fishes and fisheries in developed and developing countries. Scientists, environmental managers, non-governmental organizations, politicians, regulatory authorities and the media all have important roles to play in overcoming challenges to inland fisheries. Failure to engage the public in freshwater conservation and management issues will impede efforts to stem the loss of freshwater habitats, fisheries and aquatic biodiversity. Thankfully, there are opportunities to learn from success stories related to other

  9. OptoTracker project proposal

    Celentano, A

    2016-01-01

    The project OptoTracker aims to investigate a new approach to track charged particles in a scintillating material, by using the optical signal. Our idea is to reconstruct the trajectory of a charged particle by collecting the scintillation light emitted along the path with pixelized photo-detectors. This would permit to obtain an image of the track, similarly to what is done in a photographic camera. Full 3D reconstruction is performed by using both the charge distribution and the hit time information folded in a sophisticated reconstruction algorithm. This solution, compared to "traditional" tracking methods, exploits the fastest information carrier within a material: the light. Therefore, an optical tracking detector would be intrinsically capable of sustaining a very high interaction rate. Moreover, the intrinsic resolution would not be limited by carriers diffusion, as happens in charge-transport based detectors. This new technology could have a very large impact both on beam experiments, thanks to the po...

    The tracker of CMS will fully consist of silicon micro-strip and pixel sensors. Building a detector with 210 m/sup 2/ sensor surface in about 3 years requires a tightly controlled construction schedule. All different aspects of the production are exercised within a pre- production of 200 modules (Milestone 200) to identify and eliminate possible bottlenecks and to test the complete electronic chain. The quality, process stability and radiation hardness of the silicon sensors will be permanently monitored. Automatic assembly procedure and industrial bonding machines will guarantee a fast and reliable construction. All modules will be tested for signal, noise and pedestals at room temperature and operation temperature of -10 degrees C. Quality assurance of the Milestone 200 sensors and modules including irradiation and stability tests are presented. (6 refs).

    The Fast TracKer (FTK) will perform global track reconstruction after each Level-1 trigger accept to enable the software-based High Level Trigger to have early access to tracking information. FTK is a dedicated processor based on a mixture of advanced technologies. Modern, powerful Field Programmable Gate Arrays (FPGAs) form an important part of the system architecture, and the large level of computing power required for pattern recognition is provided by incorporating standard-cell ASICs named Associative Memory (AM). FTK provides global track reconstruction in the full inner silicon detector in approximately 100 microseconds with resolution comparable to the offline algorithms. It allows a fast and precise detection of the primary and secondary vertex information. The track and vertex information is then used by the High Level Trigger algorithms, allowing highly improved trigger performance for the important signatures such as b-jets. In this paper, the architecture and the hardware development status of FT...

    Although research has established the importance for health of a sense of personal control at work, the implications of this for women have not been adequately studied. Using quantitative data from the Australian Longitudinal Study on Women's Health and qualitative data from an associated study, here we examine women's health and sense of control in relation to family and employment commitments. In line with other research, 'demand over-load' is found to be important for sense of control, but both 'over-load' and 'control' prove complex, as illustrated by the finding that good mental health is associated with satisfaction with, rather than actual, hours of employment. In the contemporary western context of longer working hours, increasing time strain, and gender relations shaped within a neo-liberal, individualised social environment, the findings suggest that as life speeds up, 'control' and the health effects of 'busyness', need to be understood not merely as personal matters, but rather as potentially important public health issues.

    Non-alcoholic fatty liver disease (NAFLD) is a multifactorial condition that encompasses a wide spectrum of liver abnormalities ranging from simple liver steatosis to steatohepatitis (non-alcoholic steatohepatitis), which may be associated with fibrosis and progress to cirrhosis and end-stage liver disease. NAFLD has recently become the most common cause of chronic liver disease in children and adolescents. NAFLD prevalence, alongside obesity, continues to increase among pediatric patients. Obesity is believed to represent a major risk factor for NAFLD, which is considered to be the liver presentation of the metabolic syndrome. Although the pathogenesis of NAFLD is not fully understood, the notion that multiple factors affect disease development and progression is widely accepted. Both genetic background and environmental factors contribute to NAFLD development. A more complete understanding of the pathogenesis may aid in developing non-invasive diagnostic tools and identifying new therapeutic targets. Liver biopsy currently remains the gold standard for NAFLD diagnosis and staging. Although lifestyle and diet modifications are key in NAFLD treatment, the development of new pharmacological therapies is crucial for patients who are unresponsive to first-line therapy. Pediatric NAFLD is an increasing public health issue that remains underdiagnosed. A large-scale screening in the high-risk population, especially among the overweight pediatric patients, should be considered, including measurement of serum transaminases and liver ultrasound. It is crucial to treat this condition as soon as possible in order to avoid the progression to end-stage liver disease.

  2. Future Public Policy and Ethical Issues Facing the Agricultural and Microbial Genomics Sectors of the Biotechnology Industry: A Roundtable Discussion

    2003-09-12

    On September 12, 2003, the University of Maryland School of Law's Intellectual Property and Law & Health Care Programs jointly sponsored and convened a roundtable discussion on the future public policy and ethical issues that will likely face the agricultural and microbial genomics sectors of the biotechnology industry. As this industry has developed over the last two decades, societal concerns have moved from what were often local issues, e.g., the safety of laboratories where scientists conducted recombinant DNA research on transgenic microbes, animals and crops, to more global issues. These newer issues include intellectual property, international trade, risks of genetically engineered foods and microbes, bioterrorism, and marketing and labeling of new products sold worldwide. The fast paced nature of the biotechnology industry and its new developments often mean that legislators, regulators and society, in general, must play ''catch up'' in their efforts to understand the issues, the risks, and even the benefits, that may result from the industry's new ways of conducting research, new products, and novel methods of product marketing and distribution. The goal of the roundtable was to develop a short list of the most significant public policy and ethical issues that will emerge as a result of advances in these sectors of the biotechnology industry over the next five to six years. More concretely, by ''most significant'' the conveners meant the types of issues that would come to the attention of members of Congress or state legislators during this time frame and for which they would be better prepared if they had well researched and timely background information. A concomitant goal was to provide a set of focused issues for academic debate and scholarship so that policy makers, industry leaders and regulators would have the intellectual resources they need to better understand the issues and concerns at stake.

    To deal with Big Data flood from the ATLAS detector most events have to be rejected in the trigger system. the trigger rejection is complicated by the presence of a large number of minimum-bias events – the pileup. To limit pileup effects in the high luminosity environment of the LHC Run-2, ATLAS relies on full tracking provided by the Fast TracKer (FTK) implemented with custom electronics. The FTK data processing pipeline has to be simulated in preparation for LHC upgrades to support electronics design and develop trigger strategies at high luminosity. The simulation of the FTK - a highly parallelized system - has inherent performance bottlenecks on general-purpose CPUs. To take advantage of the Grid Computing power, the FTK simulation is integrated with Monte Carlo simulations at the Production System level above the ATLAS workload management system PanDA. We report on ATLAS experience with FTK simulations on the Grid and next steps for accommodating the growing requirements for resources during the LHC R...

  4. The LHCb Upstream Tracker Project

    CERN Document Server

    Steinkamp, Olaf

    2015-01-01

    The LHCb detector performs searches for New Physics in CP-violating observables and rare heavy-quark decays at the LHC. A comprehensive upgrade is planned for the long shutdown of the LHC in 2018/19. A goal of this upgrade is to abolish hardware triggers and read out the full detector at 40 MHz. This requires to replace the existing TT station upstream of the LHCb magnet by a new silicon micro-strip detector, the Upstream Tracker (UT). The UT will have a new front-end chip compatible with 40 MHz readout, silicon sensors with improved radiation hardness, finer readout granularity, and improved acceptance coverage at small polar angles. The outer region of each detection layer will be covered by p-in-n sensors with 10 cm long strips and a pitch of about 180 mum, while n-in-p sensors with half the pitch and strip length will be employed in the regions of highest particle density close to the beam pipe. The innermost sensors will have a circular cutout to optimize the forward acceptance. The front-end chip is bei...

    The DArk Matter Particle Explorer (DAMPE) satellite has been successfully launched on the 17th December 2015. It is a powerful space detector designed for the identification of possible Dark Matter signatures thanks to its capability to detect electrons and photons with an unprecedented energy resolution in an energy range going from few GeV up to 10 TeV. Moreover, the DAMPE satellite will contribute to a better understanding of the propagation mechanisms of high energy cosmic rays measuring the nuclei flux up to 100 TeV. DAMPE is composed of four sub-detectors: a plastic strip scintillator, a silicon-tungsten tracker-converter (STK), a BGO imaging calorimeter and a neutron detector. The STK is made of twelve layers of single-sided AC-coupled silicon micro-strip detectors for a total silicon area of about 7 $m^2$ . To promote the conversion of incident photons into electron-positron pairs, tungsten foils are inserted into the supporting structure. In this document, a detailed description of the STK constructi...

  6. Upgrade of the CMS Tracker

    Klein, Katja

    2013-01-01

    The performance of the Tracker of the CMS experiment, comprising of a pixel and a strip detector, has so far been excellent, as reflected in the wealth of beautiful physics results from CMS. However, the foreseen increases of both the instantaneous and the integrated luminosity by the LHC during the next ten years will necessitate a stepwise upgrade of the CMS tracking detector. \\\\ In the extended end-of-year shutdown 2016/17 the pixel detector will be exchanged. The new device is designed for an instantaneous luminosity of $2\\cdot 10^{34}$\\,cm$^{-2}$s$^{-1}$ and an integrated luminosity of 500\\,fb$^{-1}$. The number of layers will be increased from three to four in the barrel part and from two to three in the end caps, thus providing four-hit coverage over the full pseudorapidity range. A smaller beampipe allows the reduction of the radius of the innermost layer, improving the tracking performance. Further improvements include a new readout chip, reduction of material, and the installation of more effi...

    Fenwick, S G; Robertson, L; Wilks, C R

    2009-08-01

    This article discusses the integration of global and veterinary public health issues into the Australian veterinary curriculum. Formal veterinary education in Australia has a history of over 100 years and veterinarians have played a major role in the control of zoonotic and transboundary diseases for an even longer period. Australia is the largest exporter of red meat and live animals in the world. Therefore, educating veterinarians to promote and ensure food safety and animal welfare is prominent in Australian veterinary curricula. Veterinary degrees are accredited to allow Australian graduates to work professionally overseas, including in the United Kingdom and United States of America, and, in recent years, globalisation of the student body at Australian veterinary schools has occurred. For this reason, an appropriately broad curriculum is required to produce graduates who are able to address challenges in veterinary public health throughout the world. A Public Health University Network has been established to harmonise the veterinary public health curricula at the various veterinary schools and to develop the 'Australian veterinary public health philosophy', with its links to global issues and the 'One World, One Health' concept. Finally, conclusions are drawn on the implications of veterinary public health teaching in Australia and the preparation of Australian graduates for the global profession.

    Full Text Available Information on livestock movement, animal food products processing facilities, meat inspection methods, official meat inspection records and distribution and marketing systems for processed products in Imo state, Nigeria needed for policy development interventions in the sector are not fully understood. The primary data generated with the aid of personal interviews, field observations and secondary data obtained from records accumulated by the department of veterinary services Imo state from 2001 to 2004 were used to investigate the environmental and public health issues of animal food products delivery system in state. Majority of trade animals supplied to the state originated from the northern states of the country and were brought in with trucks by road. Only two veterinary control posts served the whole state thus resulting in non-inspection and taxing of a large proportion of trade animals. Official record of trade animals supplied to the state from 2001 to 2004 ranged from 45000 – 144000 for cattle, 23000 – 96000 for goats and 11000 – 72000 for sheep per annum, with supplies increasing steadily across the years. Official slaughter points in the state were principally low-grade quality slaughter premises consisting of a thin concrete slab. Meat handling was very unhygienic with carcasses dressed beside refuse heaps of over 2 years standing. Carcasses were dragged on the ground and transported in taxi boots and open trucks. Meat inspection at these points was not thorough because of stiff resistance of butchers to carcass condemnation. Official meat inspection records for the state from 2001 to 2004 revealed that overall totals of 159,000 cattle, 101,000 goats and 67,000 sheep were slaughtered. This accounted for about 56, 57 and 57% shortfall of cattle, goat and sheep respectively supplied to the state and represents the volume of un-inspected animals during the study period. Fascioliasis and tuberculosis were the most common

    2010-12-01

    Full Text Available The article presents the theoretical and methodological approaches that guide the research entitled “An approach to social representations of public issues in students of the University Los Libertadores, through their interpretation of images”, advanced in 2010. It presents philosophical and sociological conceptions of the public sphere as a general frame of reference and contrast for the investigation. It is proposed heuristically a “topology” of the public sphere, to visualize their locations and levels of constitution. Tackling the question of the constitution of the public sphere some observations are made about the role played by communication technologies. Finally, we make explicit the methodological elements to be used in this qualitative investigation: the theory of social representations, with the specific technique of images interpretation.

    Full Text Available The article explores the emergence of issues and the formation of public problems that constitute the security agenda in Argentina in the democratic stage from processes associated to the public problematisation of violent deaths constituted as shocking cases. The analysis integrates reconstructions of shocking cases in the register of public action with a review of research from social sciences presenting dimensions of violent death and problems related to national security agenda. As a point of arrival we emphasize the capacity that currently expresses insecurity to absorb and integrate dimensions, a problem which it is constituted as a privileged cultural script for the understanding of violence, which synthesizes social meanings of risk and serves as a platform for political demand for large segments of the public

    2013-03-01

    Full Text Available Since the declaration of Malaysian independence, the public sector has significantly contributed to the country’s development. In the 1990s, a new procurement system was developed due to CIBD various changes in the construction industry. Since that period, the poor quality of public sector projects has started to attract public attention. This paper describes a study that was conducted to identify the dominant public procurement systems in place, the problems associated with these systems, and the satisfaction level of the industry players in the Malaysian construction industry. The results were drawn from 84 survey responses and interviews with industry players. The public sector is using a traditional system inherited from the British, with an intention to adopt new procurement systems. Aside from the disputes that are present in most systems, the public sector seems to encounter particular problems in relation to capabilities, time, and cost of the major procurement systems used. Traditional work culture and the industry environment influence public sector practice, which accounts for the modifications of each procurement system used. Thus, the full advantages of using an alternative procurement system may not be realised in public sector organizations. This produces an average level of satisfaction gained from the procurement system adopted. As a developing country, Malaysia needs to exert significant efforts to improve the public procurement system.

    2015-01-01

    The "Framework for the Ethical Conduct of Public Health Initiatives", developed by Public Health Ontario, is a practical guide for assessing the ethical implications of evidence-generating public health initiatives, whether research or non-research activities, involving people, their biological materials or their personal information. The Framework is useful not only to those responsible for determining the ethical acceptability of an initiative, but also to investigators planning new public health initiatives. It is informed by a theoretical approach that draws on widely shared bioethical principles. Two considerations emerge from both the theoretical framework and its practical application: the line between practice and research is often blurred; public health ethics and biomedical research ethics are based on the same common heritage of values.

  16. The CMS all silicon Tracker simulation

    CERN Document Server

    Biasini, Maurizio

    2009-01-01

    The Compact Muon Solenoid (CMS) tracker detector is the world's largest silicon detector with about 201 m$^2$ of silicon strips detectors and 1 m$^2$ of silicon pixel detectors. It contains 66 millions pixels and 10 million individual sensing strips. The quality of the physics analysis is highly correlated with the precision of the Tracker detector simulation which is written on top of the GEANT4 and the CMS object-oriented framework. The hit position resolution in the Tracker detector depends on the ability to correctly model the CMS tracker geometry, the signal digitization and Lorentz drift, the calibration and inefficiency. In order to ensure high performance in track and vertex reconstruction, an accurate knowledge of the material budget is therefore necessary since the passive materials, involved in the readout, cooling or power systems, will create unwanted effects during the particle detection, such as multiple scattering, electron bremsstrahlung and photon conversion. In this paper, we present the CM...

    Full Text Available Background: The United Arab Emirates (UAE is a rapidly developing country composed of a multinational population with varying educational backgrounds, religious beliefs, and cultural practices, which pose a challenge for population-based public health strategies. A number of public health issues significantly contribute to morbidity and mortality in the UAE. This article summarises the findings of a panel of medical and public health specialists from UAE University and various government health agencies commissioned to report on the health status of the UAE population. Methods: A systematic literature search was conducted to retrieve peer-reviewed articles on health in the UAE, and unpublished data were provided by government health authorities and local hospitals. Results: The panel reviewed and evaluated all available evidence to list and rank (1=highest priority the top four main public health issues: 1 Cardiovascular disease accounted for more than 25% of deaths in 2010; 2 Injury caused 17% of mortality for all age groups in 2010; 3 Cancer accounted for 10% of all deaths in 2010, and the incidence of all cancers is projected to double by 2020; and 4 Respiratory disorders were the second most common non-fatal condition in 2010. Conclusion: The major public health challenges posed by certain personal (e.g. ethnicity, family history, lifestyle, occupational, and environmental factors associated with the development of chronic disease are not isolated to the UAE; rather, they form part of a global health problem, which requires international collaboration and action. Future research should focus on population-based public health interventions that target the factors associated with the development of various chronic diseases.

A systematic literature search was conducted to retrieve peer-reviewed articles on health in the UAE, and unpublished data were provided by government health authorities and local hospitals. The panel reviewed and evaluated all available evidence to list and rank (1=highest priority) the top four main public health issues: 1) Cardiovascular disease accounted for more than 25% of deaths in 2010; 2) Injury caused 17% of mortality for all age groups in 2010; 3) Cancer accounted for 10% of all deaths in 2010, and the incidence of all cancers is projected to double by 2020; and 4) Respiratory disorders were the second most common non-fatal condition in 2010. The major public health challenges posed by certain personal (e.g. ethnicity, family history), lifestyle, occupational, and environmental factors associated with the development of chronic disease are not isolated to the UAE; rather, they form part of a global health problem, which requires international collaboration and action. Future research should focus on population-based public health interventions that target the factors associated with the development of various chronic diseases.

    Background The United Arab Emirates (UAE) is a rapidly developing country composed of a multinational population with varying educational backgrounds, religious beliefs, and cultural practices, which pose a challenge for population-based public health strategies. A number of public health issues significantly contribute to morbidity and mortality in the UAE. This article summarises the findings of a panel of medical and public health specialists from UAE University and various government health agencies commissioned to report on the health status of the UAE population. Methods A systematic literature search was conducted to retrieve peer-reviewed articles on health in the UAE, and unpublished data were provided by government health authorities and local hospitals. Results The panel reviewed and evaluated all available evidence to list and rank (1=highest priority) the top four main public health issues: 1) Cardiovascular disease accounted for more than 25% of deaths in 2010; 2) Injury caused 17% of mortality for all age groups in 2010; 3) Cancer accounted for 10% of all deaths in 2010, and the incidence of all cancers is projected to double by 2020; and 4) Respiratory disorders were the second most common non-fatal condition in 2010. Conclusion The major public health challenges posed by certain personal (e.g. ethnicity, family history), lifestyle, occupational, and environmental factors associated with the development of chronic disease are not isolated to the UAE; rather, they form part of a global health problem, which requires international collaboration and action. Future research should focus on population-based public health interventions that target the factors associated with the development of various chronic diseases. PMID:23394856

  1. Public health surveillance data: legal, policy, ethical, regulatory, and practical issues.

    Bernstein, Amy B; Sweeney, Marie Haring

    2012-07-27

    In the United States, data systems are created by the ongoing, systematic collection of health, demographic, and other information through federally funded national surveys, vital statistics, public and private administrative and claims data, regulatory data, and medical records data. Certain data systems are designed to support public health surveillance and have used well-defined protocols and standard analytic methods for assessing specific health outcomes, exposures, or other endpoints. However, other data systems have been designed for a different purpose but can be used by public health programs for surveillance. Several public health surveillance programs rely substantially on others' data systems. An example of data used for surveillance purposes but collected for another reason is vital statistics data. CDC's National Center for Health Statistics (NCHS) purchases, aggregates, and disseminates vital statistics (birth and death rates) that are collected at the state level. These data are used to understand disease burden, monitor trends, and guide public health action. Administrative data also can be used for surveillance purposes (e.g., Medicare and Social Security Disability data that have been linked to survey data to monitor changes in health and health-care use over time).

    Full Text Available This paper provides a review of the past extreme weather events encountered in Romania, threatening the physical and psychological health of millions of people, damaging economy, infrastructure and communities, rendering different types of vulnerability. The impact of natural disaster on health is felt globally at different degrees depending on the relief, and particularly on the specific prone areas in each country. The fundamental objective of this work is to reveal a method for estimating the existing vulnerabilities of the population, mainly by socio-demographic indicator analyses, quantified by developing a Public Health Vulnerability Index (PHVI, for a future estimation of the social susceptibility area to natural hazards. By means of a selected area of interest, which highlights socio-demographic analysis in the field of public health, it is revealed the composition followed by the processing method of a partial Public Health Vulnerability Index.

  1. Key Data Gaps Regarding the Public Health Issues Associated with Opioid Analgesics.

    Schmidt, Teresa D; Haddox, J David; Nielsen, Alexandra E; Wakeland, Wayne; Fitzgerald, John

    2015-10-01

    Most pharmaceutical opioids are used to treat pain, and they have been demonstrated to be effective medications for many. Their abuse and misuse pose significant public health concerns in the USA. Research has provided much insight into the prevalence, scope, and drivers of opioid abuse, but a holistic understanding is limited by a lack of available data regarding key aspects of this public health problem. Twelve data gaps were revealed during the creation of a systems-level computer model of medical use, diversion, nonmedical use, and the adverse outcomes associated with opioid analgesics in the USA. Data specific to these gaps would enhance the validity and real-world applications of systems-level models of this public health problem and would increase understanding of the complex system in which use and abuse occur. This paper provides an overview of these gaps, argues for the importance of closing them, and provides specific recommendations for future data collection efforts.

    2007-08-01

    Full Text Available In this article I consider the ways in which activists in the British suffrage movement became the public historians of their own pasts. I analyse the different forms in which the history of suffrage feminism was created and the ways in which it both drew upon former traditions of the labour movement and conventions of public memorialisation. I consider the ways in which the Australian suffrage campaign has been memorialised and differences between this and the British position. I raise a number of questions about ways in which public historians might explore the creation of collective histories and the role of individuals within that process arising from this initial comparative analysis.

  5. Shaping public opinion on the issue of childbirth; a critical analysis of articles published in an Australian newspaper.

    McIntyre, Meredith J; Francis, Karen; Chapman, Ysanne

    2011-06-28

    The Australian government has announced a major program of reform with the move to primary maternity care, a program of change that appears to be at odds with current general public perceptions regarding how maternity care is delivered. A critical discourse analysis of articles published in 'The Age', a newspaper with national distribution, subsequent to the release of the discussion paper by the Australian Government in 2008 was undertaken. The purpose was to identify how Australian maternity services are portrayed and what purpose is served by this representation to the general public. Findings from this critical discourse analysis revealed that Australian maternity services are being portrayed to the general public as an inflexible outdated service struggling to meets the needs of pregnant women and in desperate need of reform. The style of reporting employed in this newspaper involved presenting to the reader the range of expert opinion relevant to each topic, frequently involving polarised positions of the experts on the issue. The general public are presented with a conflict, caught between the need for changes that come with the primary maternity model of care and fear that these change will undermine safe standards. The discourse; 'Australia is one of the safest countries in which to give birth or be born, what is must be best', represents the situation where despite major deficiencies in the system the general public may be too fearful of the consequences to consider a move away from reliance on traditional medical-led maternity care.

  5. The global snakebite crisis--a public health issue misunderstood, not neglected.

    Science.gov (United States)

    Simpson, Ian D; Norris, Robert L

    2009-01-01

    The global problem of venomous snakebite continues to attract attention despite it being described as a "neglected" issue. The current focus of the World Health Organization (WHO) remains anti-snake venom quality, although "availability and sustainability" of supply are consistently described as the key issues. Sustainability of antivenom supply has been elusive, with cost and pricing in developing countries being cited as the major reasons. The current WHO approach fails to explore the cost issue, but rather focuses on quality improvements, which may well adversely affect the costs of a product already perceived to be 'unaffordable.' The reference to cost and price indicates a marketing-based perspective may well give more relevant solutions to the snakebite crisis. This paper introduces a marketing model to examine global snakebite and to identify if the current approach is relevant and effective. The "4 Ps" model examines if the correct products are available, whether sufficient information exists concerning estimated market size, whether the assumptions frequently made about the costs of the product are correct and fully understood, if the product is promoted properly, and whether the method by which the product reaches the end user is optimum. The resulting analysis demonstrates that the current approach is characterized by a misunderstanding of the nature of the global snakebite problem. Further, a lack of implementation of key solutions, such as training doctors in developing countries with relevant protocols, has inevitably led to a lack of improvement in the snakebite arena over the last 30 years.

    Purpose:This study aims to construct an ontology to model the semantics of social media streams,in particular,trending topics and public issues.Design/methodology/approach:Our knowledge base included 10 public events and topics from Weibo respectively,which were collected through keyword search and a crawler program.We used a semi-automatic approach to model and annotate the semantics in social media,and adapted the multi-layered ontology to refine the design based on previous researches,then we used named entity recognition(NER) to extract entities to instantiate the ontology.Relationships were extracted based on co-occurrence measures.Finally,we manually conducted post-filtering evaluation and edited the extracted entities and relationships.Findings:An initial assessment demonstrated that our multi-layered ontology supports various types of queries and analyses in the public issue knowledge base(PIKB),which can serve as an effective tool to query,understand and trace public issues.Research limitations:Manual involvement cannot meet the requirements for challenges of sustainable developments.Since the relationships extracted are fully based on the co-occurrence of entities,rich semantic relationships,such as how much the key players have been involved,could not be fully reflected.Besides,the user evaluation is necessary for further ontology assessment.Practical implications:The PIKB can be used by regular Web users and policy makers to query,understand,and make sense of public events and topics.The methodology and reusable ontology model are useful for institutions that are interested in making use of the social media data.Originality/value:In this study,a multi-layered ontology is applied to model the evolving semantics of public events and trending topics in social media,and the semi-automatic approach could make it possible to extract entities and relationships from large amount of unstructured short texts of user generated content(UGC) from social media.

  7. NHS dental care and the issues of public service ethos, governance, accountability and probity.

    2009-06-01

    A decision by any government to intervene in dental care requires that accountability arrangements exist and that the public has faith in them. Such arrangements require a range of governance mechanisms that in turn create routes of accountability. If accountability is to have meaning an appropriate probity system is necessary. Existing probity arrangements in the NHS dental care system are far from ideal: the checks on claims are far less vigorous than under the previous contractual agreement. While the Dental Reference Service continues to refine its probity activities there are few, if any, assessments of the quality of diagnosis and treatment planning let alone the quality of the treatment provided, along with financial shortfalls. The nature of the contract introduced in April 2006 means that, even with compliance, its use as a quality assurance mechanism is substantially weaker. To address these shortfalls requires improvements in the governance arrangements a key element of which is clarity in accountability. Accountability provides an understanding of how a delivery system works, the pressures and incentives facing its actors and allows for better reform design and implementation. If a public dental service is to have excellent outcomes, be fair and equitable and offer value for money the present failings must be addressed. As has been identified in other public services: "...certain assumptions appear to be based on a belief that these standards were general throughout the public sector and would be maintained or adapted during periods of change. Little attention was given to what compromises the standards, how they are perceived and implemented across the public sector and who monitors or polices them, particularly in times of change." (Doig, 1995). The development of improved probity arrangements and a suitable contract through which the service delivered is specified would be a starting point. Perhaps then both the public and the profession can begin to

  8. Protecting the public's health following the Virginia Tech tragedy: issues of law and policy.

    Hodge, James G

    2007-09-01

    Assessing legal responsibility in the aftermath of the April 2007 tragedy at Virginia Polytechnic Institute and State University (Virginia Tech) is inevitable. Beyond assigning blame, law- and policymakers should examine ways to protect the public from future incidences of gun violence on campuses and other settings. Although no combination of legal responses may fully deter individuals who are intent on causing significant harm, select legal reforms have the potential to prevent future acts of gun violence. These reforms include considering more restrictive gun laws nationally, reporting individuals with known mental impairments that may endanger themselves or others to federal or state databases, and refining laws that limit institutions from acting in advance to address prospectively dangerous people. Each of these reforms has the potential to reduce acts of gun violence to improve the public's health, but also implicates individual rights and interests.

    2011-11-01

    According to the Protection against Infection Act (IfSG), schools have to identify their arrangements of standard operating procedures (SOPs) for hygienic conditions, and the public health departments are obliged to check the hygienic conditions in schools. Here, practical experience with these topics in Frankfurt/Main, Germany, is presented.Although all schools had been informed about their duties according to IfSG in 2001, only 44% (80/180 schools) of them were able to present their SOPs when requested to do so by the public health department in 2006. Complaints about bad sanitary hygiene in schools have to be confirmed, often even in recently redeveloped facilities, because of vandalism. The equipment of washing basins was improved very well during the influenza pandemic in 2009. In 2010, however, a tendency to deterioration had been observed. With data on high levels on indoor contamination (particles and CO2) in class rooms in 2006, the city increased the frequency of cleaning and launched a programme on proper ventilation in classrooms. However, a study on ventilation in 29 schools in 2009 resulted in very high levels of CO2; obviously the recommendation to ventilate the classrooms every break are neglected. Large studies on drinking water quality exhibited good data, with the exception of high Legionella contaminations in hot water systems supplying the showers in gymnasiums. Major redevelopment measures were necessary.Hygienic conditions in schools should be improved urgently. The public health departments should increase their consulting services as well as their control visits in schools - with the aim to improve hygiene in schools. Responsibility of the schools as well as of the individuals in the schools is demanded as well. More public attention to this topic seems mandatory, may be via a "signal light - red-yellow-green" for schools? © Georg Thieme Verlag KG Stuttgart · New York.

    Despite the recent rapid development of policies to counteract physical inactivity (PI), only a small number of systematic analyses on the evolution of these policies exists. In this article we analyze how PI, as a public health issue, "translates" into a policy-making issue. First, we discuss why PI has become an increasingly important public health issue during the last two decades. We then follow Guy Peters and conceptualize PI as a "policy problem" that has the potential to be linked to policy instruments and policy impact. Analysis indicates that PI is a policy problem that i) is chronic in nature; ii) involves a high degree of political complexity; iii) can be disaggregated into smaller scales; iv) is addressed through interventions that can be difficult to "sell" to the public when their benefits are not highly divisible; v) cannot be solved by government spending alone; vi) must be addressed through a broad scope of activities; and vii) involves interdependencies among both multiple sectors and levels of government.We conclude that the new perspective on PI proposed in this article might be useful and important for i) describing and mapping policies to counteract PI in different contexts; ii) evaluating whether or not existing policy instruments are appropriate to the policy problem of PI, and iii) explaining the factors and processes that underlie policy development and implementation. More research is warranted in all these areas. In particular, we propose to focus on comparative analyses of how the problem of PI is defined and tackled in different contexts, and on the identification of truly effective policy instruments that are designed to "solve" the PI policy problem.

  15. CMS tracker slides into centre stage

    CERN Multimedia

    2006-01-01

    As preparations for the magnet test and cosmic challenge get underway, a prototype tracker has been carefully inserted into the centre of CMS. The tracker, in its special platform, is slowly inserted into the centre of CMS. The CMS prototype tracker to be used for the magnet test and cosmic challenge coming up this summer has the same dimensions -2.5 m in diameter and 6 m in length- as the real one and tooling exactly like it. However, the support tube is only about 1% equipped, with 2 m2 of silicon detectors installed out of the total 200 m2. This is already more than any LEP experiment ever used and indicates the great care needed to be taken by engineers and technicians as these fragile detectors were installed and transported to Point 5. Sixteen thousand silicon detectors with a total of about 10 million strips will make up the full tracker. So far, 140 modules with about 100 000 strips have been implanted into the prototype tracker. These silicon strips will provide precision tracking for cosmic muon...

    We have constructed and deployed a fast digital solar tracker aboard a moving ground-based platform. The tracker consists of two rotating mirrors, a lens, an imaging camera, and a motion compensation system that provides the Euler angles of the mobile platform in real time. The tracker can be simultaneously coupled to UV-Vis and Fourier transform infrared spectrometers, making it a versatile tool to measure the absorption of trace gases using solar incoming radiation. The integrated system allows the tracker to operate autonomously while the mobile laboratory is in motion. Mobile direct sun differential optical absorption spectroscopy (mobile DS-DOAS) observations using this tracker were conducted during summer 2014 as part of the Front Range Air Pollution and Photochemistry Experiment (FRAPPE) in Colorado, USA. We demonstrate an angular precision of 0.052° (about 1/10 of the solar disk diameter) during research drives and verify this tracking precision from measurements of the center to limb darkening (CLD, the changing appearance of Fraunhofer lines) in the mobile DS-DOAS spectra. The high photon flux from direct sun observation enables measurements of nitrogen dioxide (NO2) slant columns with high temporal resolution and reveals spatial detail in the variations of NO2 vertical column densities (VCDs). The NO2 VCD from DS-DOAS is compared with a co-located MAX-DOAS instrument. Overall good agreement is observed amid a highly heterogeneous air mass.

    2015-01-01

    A software tool for estimating cross-boresight error of a star tracker combined with an inertial measurement unit (IMU) was developed to support trade studies for the Integrated Radio and Optical Communication project (iROC) at the National Aeronautics and Space Administration Glenn Research Center. Typical laser communication systems, such as the Lunar Laser Communication Demonstration (LLCD) and the Laser Communication Relay Demonstration (LCRD), use a beacon to locate ground stations. iROC is investigating the use of beaconless precision laser pointing to enable laser communication at Mars orbits and beyond. Precision attitude knowledge is essential to the iROC mission to enable high-speed steering of the optical link. The preliminary concept to achieve this precision attitude knowledge is to use star trackers combined with an IMU. The Star Tracker Accuracy (STAcc) software was developed to rapidly assess the capabilities of star tracker and IMU configurations. STAcc determines the overall cross-boresight error of a star tracker with an IMU given the characteristic parameters: quantum efficiency, aperture, apparent star magnitude, exposure time, field of view, photon spread, detector pixels, spacecraft slew rate, maximum stars used for quaternion estimation, and IMU angular random walk. This paper discusses the supporting theory used to construct STAcc, verification of the program and sample results.

    Sparse coding ( SC) based visual tracking ( l1⁃tracker) is gaining increasing attention, and many related algorithms are developed. In these algorithms, each candidate region is sparsely represented as a set of target tem⁃plates. However, the structure connecting these candidate regions is usually ignored. Lu proposed an NLSSC⁃tracker with non⁃local self⁃similarity sparse coding to address this issue, which has a high computational cost. In this study, we propose an Euclidean local⁃structure constraint based sparse coding tracker with a smoothed Euclidean local structure. With this tracker, the optimization procedure is transformed to a small⁃scale l1⁃optimization problem, sig⁃nificantly reducing the computational cost. Extensive experimental results on visual tracking demonstrate the effectiveness and efficiency of the proposed algorithm.

  20. The Role of Violence Against Women Act in Addressing Intimate Partner Violence: A Public Health Issue

    Modi, Monica N.; Palmer, Sheallah

    2014-01-01

    Abstract Intimate partner violence (IPV) is defined as violence committed by a current or former boyfriend or girlfriend, spouse or ex-spouse. Each year, 1.3 to 5.3 million women in the United States experience IPV. The large number of individuals affected, the enormous healthcare costs, and the need for a multidisciplinary approach make IPV an important healthcare issue. The Violence Against Women Act (VAWA) addresses domestic violence, dating violence, sexual assault, and stalking. It emphasizes development of coordinated community care among law enforcement, prosecutors, victim services, and attorneys. VAWA was not reauthorized in 2012 because it lacked bipartisan support. VAWA 2013 contains much needed new provisions for Native Americans; lesbian, gay, bisexual, transgender, gay, and queer (LGBTQ) individuals; and victims of human trafficking but does not address the large amount of intimate partner violence in America's immigrant population. There are important remaining issues regarding intimate partner violence that need to be addressed by future legislation. This review examines the role of legislation and addresses proposals for helping victims of IPV. PMID:24299159

    2014-01-01

    An upgrade program is planned for the LHC which will smoothly bring the luminosity up to or above ${5\\times10^{34}\\,\\mathrm{cm^{-2}}\\mathrm{s^{-1}}}$ sometimes after 2020, to possibly reach an integrated luminosity of ${3000\\,\\mathrm{fb^{-1}}}$ at the end of that decade. In this ultimate scenario, called Phase-2, when LHC will reach the High Luminosity phase (HL-LHC), CMS will need a completely new Tracker detector, in order to fully exploit the highly-demanding operating conditions and the delivered luminosity. The new Tracker should have also trigger capabilities. To achieve such goals, R\\&D activities are ongoing to explore options and develop solutions that would allow including tracking information at Level-1. The design choices for the CMS pixel and outer tracker upgrades are discussed along with some highlights of the R\\&D activities and expected detector performance.

    The purpose of this study was to examine the accuracy of the vivofit activity tracker in assessing energy expenditure and step count. Thirteen participants wore the vivofit activity tracker for five days. Participants were required to independently perform 1 h of self-selected activity each day of the study. On day four, participants came to the lab to undergo BMR and a treadmill-walking task (TWT). On day five, participants completed 1 h of office-type activities. BMR values estimated by the vivofit were not significantly different from the values measured through indirect calorimetry (IC). The vivofit significantly underestimated EE for treadmill walking, but responded to the differences in the inclination. Vivofit underestimated step count for level walking but provided an accurate estimate for incline walking. There was a strong correlation between EE and the exercise intensity. The vivofit activity tracker is on par with similar devices and can be used to track physical activity.

    Full Text Available The Mental Health Commission of Canada’s (MHCC strategy calls for promoting the health and wellbeing of all Canadians and to improve mental health outcomes. Each year, one in every five Canadians experiences one or more mental health problems, creating a significant cost to the health system. Mental health is pivotal to holistic health and wellbeing. This paper presents the key findings of a comprehensive literature review of Canadian research on the relationship between settlement experiences and the mental health and well-being of immigrants and refugees. A scoping review was conducted following a framework provided by Arskey and O’Malley (Int J Soc Res Methodol 8:19–32, 2005. Over two decades of relevant literature on immigrants’ health in Canada was searched. These included English language peer-reviewed publications from relevant online databases Medline, Embase, PsycInfo, Healthstar, ERIC and CINAHL between 1990 and 2015. The findings revealed three important ways in which settlement affects the mental health of immigrants and refugees: through acculturation related stressors, economic uncertainty and ethnic discrimination. The recommendations for public health practice and policy are discussed.

    2014-09-01

    Full Text Available This article provides a structured framework for research into the accounting implications of Public Private Partnerships (PPPs. PPPs worldwide have taken on increasing significance as a tool that governments can use to develop infrastructure and for the delivery of services. Given the minimal coverage in the literature of the Victorian State Government experience to date regarding the efficacy of PPPs, this report establishes a number of parameters from which academics can conduct research into this strategy and, moreover, make policy recommendations based on those findings. Accounting principles are used to identify whether a PPP will lead to value for money. Consequently, a model is developed to define potential areas of investigation, from which a series of research questions are posed. This is important because, public sector managers need to be aware of the failures and the success stories of particular PPP projects so that lessons can be learned from these experiences. This would inform government officials of any necessary reforms that need to be undertaken for future PPPs.

    Full Text Available Finding solutions to complex health problems, such as obesity, violence, and climate change, will require radical changes in cross-disciplinary education, research, and practice. The fundamental determinants of health include many interrelated factors such as poverty, culture, education, environment, and government policies. However, traditional public health training has tended to focus more narrowly on diseases and risk factors, and has not adequately leveraged the rich contributions of sociology, anthropology, economics, geography, communication, political science, and other disciplines. Further, students are often not sufficiently trained to work across sectors to translate research findings into effective, large-scale sustainable actions.During the past 2 decades, national and international organizations have called for more effective interdisciplinary, transdisciplinary, and translational approaches to graduate education. Although it has been difficult to work across traditional academic boundaries, some promising models draw on pedagogical theory and feature cross-disciplinary training focused on real-world problems, linkage between research, professional practice, community action, and cultivation of leadership skills.We describe the development the Doctor of Public Health program at the University of California, Berkeley, USA and its efforts to improve transdisciplinary and translational research education. We stress the need for international collaboration to improve educational approaches and better evaluate their impact.

    To find the fit that is most apt for the current situation in Korea and to find new ways of identifying potential partners for the purpose of public-private partnership (PPP). The research was conducted using domestic and international literature where the concept and definition of PPP was stated, and cases of PPP reported by the World Health Organization and cases in developed countries were investigated. Data were collected from 237 PPP potential partner organization, government agencies, and the government under a special law, local governments, businesses, hospitals, and private organizations through their internet webpage. The Delphi questionnaire was given to relevant institutions and questionnaire was surveyed general hospitals. Groups that were likely to realize most of the partnership were nonprofit or nongovernmental organizations, the central government, the private sector, public healthcare services, and products. In order to secure the position of exceptional comparative advantage of international expertise in the field of healthcare, we must implement PPP strategy that is in ordinance of domestic situation.

    2014-04-01

    Over the past 5 years, a number of cases of legionellosis in Scotland have been associated with compost use; however, studies investigating sources of infection other than water systems remain limited. This study delivers the first comprehensive survey of composts commonly available in the UK for the presence of Legionella species. Twenty-two store-bought composts, one green-waste compost and one home-made compost were tested for Legionella by culture methods on BCYE-α medium, and the findings were confirmed by macrophage infectivity potentiator (mip) speciation. Twenty-two of the samples were retested after an enrichment period of 8 weeks. In total, 15 of 24 composts tested positive for Legionella species, a higher level of contamination than previously seen in Europe. Two isolates of Legionella pneumophila were identified, and Legionella longbeachae serogroup 1 was found to be one of the most commonly isolated species. L. longbeachae infection would not be detected by routine Legionella urinary antigen assay, so such testing should not be used as the sole diagnostic technique in atypical pneumonia cases, particularly where there is an association with compost use. The occurrence of Legionella in over half of the samples tested indicates that compost could pose a public health risk. The addition of general hygiene warnings to compost packages may be beneficial in protecting public health.

    To determine the characteristics of Arab Americans receiving treatment and to compare them with individuals of other ethnic groups. We used admission data (FY2005) for Michigan publicly funded substance abuse treatment (N=69,989). Arab American ethnicity (n=224 or 0.3% of admissions) was defined by codes for race, ethnicities or primary language of Arabic (n=21). Other ethnicities examined were American Indian, Hispanic, African American, and White. The number of Arab American admissions was lower than expected for the population (RR=0.25). Admissions were concentrated (81%) in metropolitan Detroit as is the community (82%, RR=.99), unlike other ethnicities. Primary drugs of abuse were alcohol (34.8%), marijuana (17.9%), heroin (17.4%) and crack cocaine (15.6%). Mean duration of use (11.2 yrs) was significantly lower than for other ethnicities. Arab American admissions were predominately male (76.3%), unemployed (62.1%) and with criminal justice involvement (58%), similar to other ethnicities. Using administrative database has its limits and may misclassify ethnicities. Based upon the available data, it appears that Arab Americans accounted for a small percentage of admissions to publicly funded substance abuse treatment in Michigan. Most of the admissions listed English as the primary language, raising concern that language may be a barrier to entry. Admission profiles were generally similar across ethnicities, except that Arab Americans were entering treatment after shorter duration of use. These data can inform development of treatment programs and outreach efforts.

  10. Price Trackers Inspired by Immune Memory

    Wilson, William; Aickelin, Uwe

    2010-01-01

    In this paper we outline initial concepts for an immune inspired algorithm to evaluate price time series data. The proposed solution evolves a short term pool of trackers dynamically through a process of proliferation and mutation, with each member attempting to map to trends in price movements. Successful trackers feed into a long term memory pool that can generalise across repeating trend patterns. Tests are performed to examine the algorithm's ability to successfully identify trends in a small data set. The influence of the long term memory pool is then examined. We find the algorithm is able to identify price trends presented successfully and efficiently.

  11. Preliminary studies of a chromaticity tracker

    Tan, Cheng-Yang; /Fermilab

    2006-03-01

    A chromaticity tracker based on a method by D. McGinnis is proposed. This method starts with the slow modulation of the accelerating RF which causes the beam to respond to it. This beam modulation can be detected transversely with a Schottky pickup which after phase demodulation, the chromaticity can be calculated from it. However, to perform phase demodulation, the carrier frequency which is the betatron tune needs to be identified. The identification of the carrier frequency falls naturally onto the phase locked loop tune tracker which when locked to the betatron tune outputs this value in real time.

By analyzing the various speeches of ten important world leaders of West Democratic Countries on terrorism of fundamentalist matrix, we will outline a contradiction: declaring the necessity of war as a condition and objective of peace. This is solved in different ways: it becomes an ambivalent strategy in the cases of Obama and Merkel, with the latter being less explicit; in the cases of Bush, Berlusconi, Blair and Rice it leads, albeit with different motivations and arguments, to a stark choice: war; whereas it disappears in the speeches of Zapatero, Prodi and Cameron, who speak of actions and strategies to combat terrorism without ever mentioning war. Without offering any value judgment of the content of the various arguments, I only take them as a pretext to reflect on the rules of ambivalent communication: a communication which starts from a clear contradiction, and argues the necessity of it, before demonstrating its usefulness and proposing strategies of action that take it into account. The essay is divided into two parts: in the first one (which is published in this issue I discuss the concept of sociological ambivalence, I distinguish ambivalence from contradictions and ambiguity and I identify the argumentative strategies of an ambivalent communication. Then I analyze the speech the President of the United States of America Barack Obama delivered on December 10, 2009 in Oslo when he received the Nobel Peace Prize as an example of “good” ambivalent communication. In the second part of the essay (which will be published in the next issue, I analyze the speeches of other world leaders as different examples of ambivalent communication.

    The inability to translate data to scientific information that can readily be incorporated by citizens into the public arena is an obstacle for science-based advocacy. This issue is particularly poignant for shale oil and natural gas development via hydraulic fracturing, as the issue has become highly politicized. Barriers to engaging in policy debate are different but highly related for community members and scientists. For citizens and interest groups, barriers including accessibility, public awareness and data presentation limit the motivation for community involvement in political interactions. To overcome such barriers, social researchers call for public engagement to move upstream and many call for a broad engagement of scientists in science-based advocacy. Furthermore surveys have shown that citizens, interest groups, and decision-makers share a broad desire for scientists to engage in environmental policy development. Regardless, scientists face a number of perceived barriers, with academics expressing the most resistance to overcoming the tension created by adherence to the scientific method and the need to engage with the broader society, described by Schneider (1990) as the 'double ethical bind'. For the scientific community the appeal of public dissemination of information beyond the scope of academic journals is limited for a number of reasons. Barriers include preservation of credibility, peer attitudes, training, and career trajectory. The result is a lack of translated information available to the public. This systematic analysis of the FracTracker platform provides an evaluation of where the features of the public engagement, GIS platform has been successful at overcoming these barriers to public dissemination, where the platform needs further development or is ill-suited to address these issues, and the development of FracTracker as an outlet for scientific researchers to engage with citizens. The analysis will also provide insight into what

  14. Transforming public utility commissions in the new regulatory environment: Some issues and ideas for managing change

    In the face of sweeping changes in utility markets and regulatory practices, public utility commissions are being forced to change in fundamental ways--to substantially transform themselves rather than to make only incremental changes in their operations. Managing this process of radical change is complicated by the fact that for the foreseeable future some portions of utility markets (e.g., water utilities) will function much as they have before. Some envision commissions in the future that are more externally focussed, that rely more on dispute resolution than adjudicatory proceedings, that concentrate on identifying and understanding competitive markets, that are more automated, and that are more likely to question old assumptions and definitions. This report identifies the considerations commissions might apply for identifying what mix of skills or fields of experise should compromise the technical staff. Factors are also identified which point towards a sectoral arrangement of staff and those factors which point toward a functional approach.

    The summer holidays are over. And like every year around this time the Staff Association comes to meet you in your Departments to inform you about the topics currently being discussed at CERN. We count very much on the exchange of views and opinions between you and us that takes place during these meetings. Once again in 2009 there are a wide range of topics to be discussed. If the stakes are generally high, this year and the next ones they are huge. This is an additional reason for the need to see a maximum number of motivated candidates stand at the forthcoming elections for the Staff Council in November 2009. For all these reasons and to help us prepare optimally for these critical deadlines, we invite all of you to attend our public meetings.

  16. ATV Accidents continue to be a major public health issue in West Virginia.

    2005-01-01

    All-terrain vehicle (ATV) riding continues to be a major public health problem in West Virginia because the state leads the nation in the rate of deaths from ATV incidents and has significantly higher death rates than all five of the bordering states. Annually, there are 24 deaths a year in West Virginia due to ATV accidents and thousands of nonfatal injuries. Sporting events using ATVs such as motocross racing have added to the burden of caring for patients who are injured in recreational activities. We report a case study of 10 patients treated over an 18-hour period in a state trauma center for injuries received while riding ATVs casually and in competition. The addition of these 10 patients to the other 108 patients seen in the ED during this period totally disrupted patient flow, caused significant delays in care of the non-trauma patients, and tied up the Radiology Department and operating rooms for an extended period.

  17. Ethical issues raised by thyroid cancer overdiagnosis: A matter for public health?

    2017-10-01

    Current practices of identifying and treating small indolent thyroid cancers constitute an important but in some ways unusual form of overdiagnosis. Overdiagnosis refers to diagnoses that generally harm rather than benefit patients, primarily because the diagnosed condition is not a harmful form of disease. Patients who are overdiagnosed with thyroid cancer are harmed by the psycho-social impact of a cancer diagnosis, as well as treatment interventions such partial or total thyroidectomy, lifelong thyroid replacement hormone, monitoring, surgical complications and other side effects. These harms seem to outweigh any putative benefit of knowing about a cancer that would not have caused problems if left undiscovered. In addition to harms to patients, thyroid cancer overdiagnosis leads to significant opportunity costs at a societal level, due to costs of diagnosis and treatment. Unlike many other overdiagnosed cancers, accurate risk stratification is possible with thyroid cancer. At the individual patient level, use of this risk information might support informed choice and/or shared decision-making, as mandated by clinical ethics frameworks. And this approach might, to some extent, help to reduce rates of diagnosis and intervention. In practice, however, it is unlikely to stem the rising incidence and associated harms and costs of overdiagnosed thyroid cancer, especially in situations where health professionals have conflicts of interest. We argue in this article that thyroid cancer overdiagnosis may be usefully understood as a public health problem, and that some public health approaches will be readily justifiable and are more likely to be effective in minimising its harms. © 2017 John Wiley & Sons Ltd.

    Full Text Available Context: A better understanding of medication safety ensures better health state among healthcare consumers. Aim: The study aims to assess general public awareness toward issues related to medication safety. Settings and Design: A cross-sectional study was conducted among general public selected conveniently in the state of Penang, Malaysia. Materials and methods: A total of 500 respondents were approached and 476 consumers participated in the survey giving a response rate of 95.2%. Statistical analysis: Data were analyzed by using SPSS version 12.0 and descriptive statistics were reported where appropriate. Results: Majority of the respondents (n=292, 61.3% stated that they were well aware of the possible side effects of their current medications. A total of 196 respondents (41.17% believed that all medicines registered in Malaysia are safe to use as these medicines have no side effects. About 40.33% (n=192 of the respondents claimed that they share their unused medicines with family and friends who are having similar illness. Majority of respondents 57.7% (n=275 were satisfied with the drug information provided by the healthcare professionals. This study also found that more than 80% of the respondents (n=409 did report that they read the labels of their medication before using. Conclusions: In this study, it was revealed that there is a moderate level of public knowledge regarding medication safety. It is evident that public underestimates the risk of their medications. There is a general lack of awareness and understanding among the public especially toward side effects.

  4. RPC Overall Efficiency Measurement from Tracker Muons

    CMS Collaboration

    2016-01-01

    From the Run-II, the RPCMuon reconstruction algorithm is included in the standard reconstruction, where the algorithm starts from the inner track and finds matched RPC hits(RPCRecHits) along its trajectory. The track extrapolation is done in this step and the results of extrapolation are stored in the muon objects. For the efficiency measurement using the track extrapolation in the RPCMuons, we require TrackerMuon identification on the muons. The TrackerMuon identification is done by extrapolating inner tracks to muon systems to find matching DT/CSC segments. The TrackerMuon and RPCMuon reconstruction are designed to run independently, to be complementary algorithms to each other. We use the tag-and-probe method to remove bias from the triggers - start from the SingleMuon dataset and require one muon(tag) to pass identification and isolation cuts but also require to be matched to the trigger object to accept the event. Then we select another muon(probe) in the event to study the efficiency, requiring Tracker...

    COSY-TOF is a very large acceptance spectrometer for charged particles using precise information on track geometry and time of flight of reaction products. It is an external detector system at the Cooler Synchrotron and storage ring COSY in Juelich. In order to improve the performance of the COSY-TOF, a new tracking detector ''Straw Tracker'' is being constructed which combines very low mass, operation in vacuum, very good resolution, high sampling density and very high acceptance. A comparison of pp{yields}d{pi}{sup +} data and a simulation using the straw tracker with geometry alone indicates big improvements with the new tracker. In order to investigate the straw tracker properties a small tracking hodoscope ''cosmic ray test facility'' was constructed in advance. It is made of two crossed hodoscopes consisting of 128 straw tubes arranged in 4 double planes. For the first time Juelich straws have been used for 3 dimensional reconstruction of cosmic ray tracks. In this illuminating field the space dependent response of scintillators and a straw tube were studied. (orig.)

  7. Computing what the public wants: some issues in road safety cost-benefit analysis.

    Hauer, Ezra

    2011-01-01

    In road safety, as in other fields, cost-benefit analysis (CBA) is used to justify the investment of public money and to establish priority between projects. It amounts to a computation by which 'few' - the CB analysts - aim to determine what the 'many' - those on behalf of which the choice is to be made - would choose. The question is whether there are grounds to believe that the tool fits the aim. I argue that the CBA tool is deficient. First, because estimates of the value of statistical life and injury on which the CBA computation rests are all over the place, inconsistent with the value of time estimates, and government guidance on the matter appears to be arbitrary. Second, because the premises of New Welfare Economics on which the CBA is founded apply only in circumstances which, in road safety, are rare. Third, because the CBA requires the computation of present values which must be questioned when the discounting is of future lives and of time. Because time savings are valued too highly when compared to life and because discounting tends to unjustifiably diminish the value of lives saved in the future, the CBA tends to bias decisions against investment in road safety.

  8. Public health and social injustice are the key issues for the decriminalization of abortion in Mexico.

    Science.gov (United States)

    1994-01-01

    Although the Second National Abortion Survey Gallup found that 88% of Mexicans believe abortion should be a woman's choice and 77% think the decriminalization of abortion would substantially reduce maternal mortality, abortion in Mexico remains governed by a 1931 criminal code. The survey was initiated by the Information and Reproductive Choice Group to provide information for the 1994 national debate on abortion. Supporters of legal abortion note that poor women resort to unsafe pregnancy terminations without regard to the criminal status of abortion. According to Patricia Mercado, co-founder of the Reproductive Choice Group, "You can be against abortion, but still allow it to be decriminalized. In other words, criminalization does not prevent women from having abortions, it only makes then have then in bad conditions. The idea is that women should be able to decide freely without risking problems of health and social justice." Despite public support for abortion legalization, survey results indicate widespread fear about acknowledging the existence of clandestine abortion. An estimated 1-2 million illegal abortions occur each year in Mexico, yet only 26% of survey respondents would admit to knowing a woman who had undergone illegal abortion.

  9. Is there a crack epidemic among students in Brazil?: comments on media and public health issues

    Directory of Open Access Journals (Sweden)

    Solange Aparecida Nappo

    Full Text Available In the past year, the Brazilian Federal Government and society have reported and acted on a crack use epidemic, which has been exacerbated by the media. This study hypothesized that crack use has not increased at the rate suggested by the Brazilian media. A cross-sectional survey was carried out in 2010 usinga multistage probabilistic representative sample of Brazilian middle and high school students in the country's 27 state capitals. A total of 50,890 valid questionnaires were weighted, analyzed and results compared to the 2004 national school survey dataset. Considering lifetime and past year crack use, no change in consumption was found between 2004 and 2010. Official data in Brazil on middle and high school students does not support the assertion of a crack epidemic widely publicized by the media. Government measures to treat and prevent crack use are encouraged; however, the term epidemic has been inappropriately used to represent the static prevalence of crack consumption among students.

    Sub-Saharan African countries are at an increased risk of the effects of global warming. Unfortunately they have the least capacity to adapt to its untoward effects. We studied public awareness of global warming, its perceived causes, effects and prevention in Kano city, northern Nigeria. Structured questionnaires were administered on a cross section of 181 adults in Kano eliciting their awareness of global warming, as well as perceived causes, effects and ways of prevention. Of the 181 respondents, 132 (72.9%) were aware of global warming mainly from electronic media (44.4%), the Internet (20.5%) and schools (18.7%). They mostly attributed it to air pollution (99.2%), use of fossil fuels (97.7%), toxic waste (78.0%) and chlorofluorocarbons (73.5%). Perceived effects of global warming include extremes of ambient temperature (97.7%), increased disease outbreaks (92.4%), floods (68.2%), droughts (51.5%) and loss of species (50.0%). Respondents opined that global warming could be prevented by using renewable sources of energy such as the sun (53.8%), massive tree planting (44.7%) and phasing out of old automobiles (43.2%). A significantly higher proportion of males, younger and educated respondents were aware of global warming. The high awareness about global warming needs to be reinforced through use of media to encourage advocacy and community action towards preventing global warming and ensuring environmental sustainability.

    Isoniazid preventive therapy (IPT) is recognised as an important component of collaborative tuberculosis (TB) and human immunodeficiency virus (HIV) activities to reduce the burden of TB in people living with HIV (PLHIV). However, there has been little in the way of IPT implementation at country level. This failure has resulted in a recent call to arms under the banner title of the 'Three I's' (infection control to prevent nosocomial transmission of TB in health care settings, intensified TB case finding and IPT). In this paper, we review the background of IPT. We then discuss the important challenges of IPT in PLHIV, namely responsibility and accountability for the implementation, identification of latent TB infection, exclusion of active TB and prevention of isoniazid resistance, length of treatment and duration of protective efficacy. We also highlight several research questions that currently remain unanswered. We finally offer practical suggestions about how to scale up IPT in the field, including the need to integrate IPT into a package of care for PLHIV, the setting up of operational projects with the philosophy of 'learning while doing', the development of flow charts for eligibility for IPT, the development and implementation of care prior to antiretroviral treatment, and finally issues around procurement, distribution, monitoring and evaluation. We support the implementation of IPT, but only if it is done in a safe and structured way. There is a definite risk that 'sloppy' IPT will be inefficient and, worse, could lead to the development of multidrug-resistant TB, and this must be avoided at all costs.

  12. Representations and coverage of non-English-speaking immigrants and multicultural issues in three major Australian health care publications

    Science.gov (United States)

    2010-01-01

    Background No recent Australian studies or literature, provide evidence of the extent of coverage of multicultural health issues in Australian healthcare research. A series of systematic literature reviews in three major Australian healthcare journals were undertaken to discover the level, content, coverage and overall quality of research on multicultural health. Australian healthcare journals selected for the study were The Medical Journal of Australia (MJA), The Australian Health Review (AHR), and The Australian and New Zealand Journal of Public Health (ANZPH). Reviews were undertaken of the last twelve (12) years (1996-August 2008) of journal articles using six standard search terms: 'non-English-speaking', 'ethnic', 'migrant', 'immigrant', 'refugee' and 'multicultural'. Results In total there were 4,146 articles published in these journals over the 12-year period. A total of 90 or 2.2% of the total articles were articles primarily based on multicultural issues. A further 62 articles contained a major or a moderate level of consideration of multicultural issues, and 107 had a minor mention. Conclusions The quantum and range of multicultural health research and evidence required for equity in policy, services, interventions and implementation is limited and uneven. Most of the original multicultural health research articles focused on newly arrived refugees, asylum seekers, Vietnamese or South East Asian communities. While there is some seminal research in respect of these represented groups, there are other communities and health issues that are essentially invisible or unrepresented in research. The limited coverage and representation of multicultural populations in research studies has implications for evidence-based health and human services policy. PMID:20044938

    One function of drug formularies is to allow health care providers to exert some control over spending. Decisions about whether to include a given medication in a formulary are based on estimates of its costs and effectiveness, relative to other treatment strategies. These decisions are made from a societal perspective, as opposed to that of individual patients, which sometimes results in conflicts. The clinical response to a medication often varies widely among subjects, which means that a small subgroup of patients might benefit dramatically, while others with the same disease do not. The result would be that a drug might appear not to be cost effective in an economic analysis, even though it is of proven value for some patients. New and innovative medications are assessed according to high standards of cost effectiveness, even though established treatments are wasteful of valuable health care resources. Moreover, quality-adjusted life-years (QALYs) discriminate against certain patient groups, including those with diseases that are associated with a high morbidity but a low mortality. Such patients often incur high indirect costs, including loss of employment income and costs incurred by family caregivers that QALYs do not reflect. Therefore, even though QALYs are transparent and widely applicable, they are not necessarily appropriate in the evaluation of a particular therapeutic intervention. A new paradigm should be developed for evaluating emerging therapies. An example would be a risk-sharing approach, whereby the pharmaceutical industry and public insurers share in the costs and rewards of introducing new treatments. This would have implications for the prices charged for new medications.

    Background The 2000 Vietnamese National Nutrition Survey showed that the population's dietary intake had improved since 1987. However, inequalities were found in food consumption between socioeconomic groups. As no national data exist on the prevalence of micronutrient deficiencies, a survey was conducted in 2010 to assess the micronutrient status of randomly selected 1526 women of reproductive age and 586 children aged 6–75 mo. Principal Findings In women, according to international thresholds, prevalence of zinc deficiency (ZnD, 67.2±2.6%) and vitamin B12 deficiency (11.7±1.7%) represented public health problems, whereas prevalence of anemia (11.6±1.0%) and iron deficiency (ID, 13.7±1.1%) were considered low, and folate (deficiencies were considered negligible. However, many women had marginal folate (25.1%) and vitamin A status (13.6%). Moreover, overweight (BMI≥23 kg/m2 for Asian population) or underweight occurred in 20% of women respectively highlighting the double burden of malnutrition. In children, a similar pattern was observed for ZnD (51.9±3.5%), anemia (9.1±1.4%) and ID (12.9±1.5%) whereas prevalence of marginal vitamin A status was also high (47.3±2.2%). There was a significant effect of age on anemia and ID prevalence, with the youngest age group (6–17 mo) having the highest risk for anemia, ID, ZnD and marginal vitamin A status as compared to other groups. Moreover, the poorest groups of population had a higher risk for zinc, anemia and ID. Conclusion The prevalence of anemia and ID in Vietnam has been markedly reduced over the last decade, but a large part of the population is still at risk for other deficiencies such as zinc, vitamin A, folate and vitamin B12 especially the youngest children aged 6–17 mo. Consequently specific interventions to improve food diversity and quality should be implemented, among them food fortification of staple foods and condiments and improvement of complementary feeding.

    Full Text Available Legislation and regulation at the state and local level can often have a greater impact on the public’s health than individual-based approaches. Elected and appointed officials have an essential role in protecting and improving public health. Despite this important role, little systematic research has been done to assess the relative importance of public health issues compared to other policy issues in times of economic hardship. This study assessed attitudes of elected and appointed decision makers in Hawaii in 2007 and 2013 to determine if priorities differed before and after the economic recession. Methods: Elected and appointed state and county officials were mailed surveys at both time points. Respondents rated the importance of 23 specified problems, of which 9 asked about specific public health issues. Results: The survey was completed by 126 (70.4% respondents in 2007 and 117(60.9% in 2013. Among the public health issues, five saw significant mean decreases. These variables included: climate change, pedestrian safety, government response to natural disasters, access to healthcare, and pandemic influenza. Obesity was the only public health issue to increase in importance across the two time points. In terms of relative ranking across the time points, only drug abuse and obesity were among the top ten priorities. Lack of public health training, pandemic influenza, and government response to natural disasters were among the bottom five priorities. Conclusions: After the economic recession, many public health issues have a lower priority among Hawaii’s policy makers than before the downturn. Additional education and advocacy is needed to keep public health issues on the minds of decision makers during tough economic times.

    The role of vitamin D in supporting the growth and maintenance of the skeleton is robust; with recent research also suggesting a beneficial link between vitamin D and other non-skeletal health outcomes, including immune function, cardiovascular health and cancer. Despite this, vitamin D deficiency remains a global public health issue, with a renewed focus in the UK following the publication of Public Health England's new Dietary Vitamin D Requirements. Natural sources of vitamin D (dietary and UVB exposure) are limited, and thus mechanisms are needed to allow individuals to achieve the new dietary recommendations. Mandatory or voluntary vitamin D food fortification may be one of the mechanisms to increase dietary vitamin D intakes and subsequently improve vitamin D status. However, for the food industry and public to make informed decisions, clarity is needed as to whether vitamins D2 and D3 are equally effective at raising total 25-hydroxyvitamin D (25(OH)D) concentrations as the evidence thus far is inconsistent. This review summarises the evidence to date behind the comparative efficacy of vitamins D2 and D3 at raising 25(OH)D concentrations, and the potential role of vitamin D food fortification as a public health policy to support attainment of dietary recommendations in the UK. The comparative efficacy of vitamins D2 and D3 has been investigated in several intervention trials, with most indicating that vitamin D3 is more effective at raising 25(OH)D concentrations. However, flaws in study designs (predominantly under powering) mean there remains a need for a large, robust randomised-controlled trial to provide conclusive evidence, which the future publication of the D2-D3 Study should provide (BBSRC DRINC funded: BB/I006192/1). This review also highlights outstanding questions and gaps in the research that need to be addressed to ensure the most efficacious and safe vitamin D food fortification practices are put in place.

    Full Text Available Injury was the largest single cause of disability-adjusted life years (DALYs and death in the Kingdom of Saudi Arabia I 2013. The vast majority of injury-related fatalities are deaths caused by road traffic. Measures to control this serious public health issue, which has significant consequences for both Saudi families and the Saudi economy as a whole, have been underway for years but with little success. Most attempts at intervening revolve around attempts for enforce stricter traffic laws and by installing automated traffic monitoring systems that will catch law breakers on camera and issue tickets and fines. While there has been much research on various factors that play a role in the high rate of road traffic injury in The Kingdom (e.g., driver behavior, animal collisions, disobeying traffic and pedestrian signals, environmental elements, virtually no attention has been given to examining why Saudi drivers behave the way that they do. This review provides a thorough account of the present situation in Saudi Arabia and discusses how health behavior theory can be used to gain a better understanding of driver behavior.

    2016-01-01

    The next LHC runs, with a significant increase in instantaneous luminosity, will provide a big challenge for the trigger and data acquisition systems of all the experiments. An intensive use of the tracking information at the trigger level will be important to keep high efficiency for interesting events despite the increase in multiple collisions per bunch crossing. In order to increase the use of tracks within the High Level Trigger, the ATLAS experiment planned the installation of a hardware processor dedicated to tracking: the Fast TracKer processor. The Fast Tracker is designed to perform full scan track reconstruction of every event accepted by the ATLAS first level hardware trigger. To achieve this goal the system uses a parallel architecture, with algorithms designed to exploit the computing power of custom Associative Memory chips, and modern field programmable gate arrays. The processor will provide computing power to reconstruct tracks with transverse momentum greater than 1 GeV in the whole trackin...

    2009-01-01

    The Physics and Data Quality Monitoring (DQM) framework aims at providing a homogeneous monitoring environment across various applications related to data taking at the CMS experiment. It has been designed to be used during online data taking as well as during offline reconstruction. The goal of the online system is to monitor detector performance and identify problems very efficiently during data collection so that proper actions can be taken. On the other hand the reconstruction or calibration problems can be detected during offline processing using the same tool. The monitoring is performed with histograms, which are filled with information from raw and reconstructed data. All histograms can then be displayed both in the central CMS DQM graphical user interface (GUI), as well as in Tracker specific expert GUIs and socalled Tracker Maps. Applications are in place to further process the information from these basic histograms by summarizing them in overview plots, by evaluating them with automated statistica...

    A detector system for assessing damage to the cores of the Fukushima Daiichi nuclear reactors by using cosmic-ray muon tomography was developed. The system consists of a pair of drift-tube tracking detectors of 7.2× 7.2-m2 area. Each muon tracker consists of 6 x-layer and 6 y-layer drift-tube detectors. Each tracker is capable of measuring muon tracks with 12 mrad angular resolutions, and is capable of operating under 50-μ Sv/h radiation environment by removing gamma induced background with a novel time-coincidence logic. An estimated resolution to observe nuclear fuel debris at Fukushima Daiichi is 0.3 m when the core is imaged from outside the reactor building.

    The LHCb Outer Tracker is a gaseous detector covering an area of 5x6 m2 with 12 double layers of straw tubes. The detector with its services are described together with the commissioning and calibration procedures. Based on data of the first LHC running period from 2010 to 2012, the performance of the readout electronics and the single hit resolution and efficiency are presented. The efficiency to detect a hit in the central half of the straw is estimated to be 99.2%, and the position resolution is determined to be approximately 200 um. The Outer Tracker received a dose in the hottest region corresponding to 0.12 C/cm, and no signs of gain deterioration or other ageing effects are observed.

    In sight of the incoming new LHC era (High Luminosity - LHC), characterized by a jump forward in the precision boundary and in the event rate, all the CMS sub-detector are developing and studying innovative strategies of trigger, pattern recognition, event timing and so on. A crucial aspect will be the online event selection: a totally new paradigm is needed, given the huge amount of events. In this picture the most granular and innermost sub-detector, the tracker, will play a decisive role. The phase-2 tracker will be involved in the L1 Trigger and, taking advantage of both the Associative Memories and the FPGA, it can ensure a trigger decision in proper time and with satisfactory performances.

    Many physics channels, and in particular events containing top quarks, produce b jets in the final state which need to be distinguished from more copious backgrounds containing only light flavored jets. Tagging of b-jets, mainly relies upon relatively distinct properties of b-hadrons such as large proper lifetime, large mass, decays to final states with high charged track multiplicities. Precise spatial reconstruction close to the interaction point and efficient track reconstruction are key ingredients for all b-tagging algorithms. These rely on stable, low noise, low occupancy and highly efficient tracking detectors. This is a short review of the results of the studies on the CMS tracker performances carried out with cosmics at the CERN Tracker Integration Facility from march to july 2007, in order to show how this performance is in line with the requirement of the CMS community for a good b-tagging.

    The Alpha Magnetic Spectrometer (AMS) is designed as a independent module for installation on the International Space Station Alpha (ISSA) in the year 2002 for an operational period of three years. The principal scientific objectives are the searches for antimatter and dark matter in cosmic rays. The AMS uses 5.5 m sup 2 of silicon microstrip sensors to reconstruct charged particle trajectories in the field of a permanent magnet. The detector design and construction covered a 3 yr period which terminated with a test flight on the NASA space shuttle Discovery during June 2-12, 1988. In this contribution, we describe the shuttle version of the AMS silicon tracker, including preliminary results of the tracker performance during the flight. (author)

    The Compact Muon Solenoid DCS (CMS) Silicon Strip Tracker is by far the largest detector ever built in micro-strip technology. It has an active surface area of 198 m{sup 2} consisting of 15,148 silicon modules with 9,316,352 readout channels read via 75,376 Analog Pipeline Voltage (APV) front-end chips and a total of 24,244 sensors. The Detector Control System (DCS) for the Tracker is a distributed control system that operates {approx}2000 power supplies for the silicon modules and also monitors its environmental sensors. The DCS receives information from about 10{sup 3} environmental probes (temperature and humidity sensors) located inside the detector's volume and values from these probes are driven through the Programmable Logic Controllers (PLC) of the Detector Safety System (DSS). A total of 10{sup 5} parameters are read out from the dedicated chips in the front-end electronics of the detector via the data acquisition system, and a total of 10{sup 5} parameters are read from the power supply modules. All these parameters are monitored, evaluated and correlated with the detector layout; actions are taken under specific conditions. The hardware for DCS consists of 10 PCs and 10 PLC systems that are continuously running the necessary control and safety routines. The DCS is a fundamental tool for the Tracker operation and its safety.

    2017-02-01

    The LHCb experiment will be upgraded during LHC Long Shutdown 2 to be able to record data at a higher instantaneous luminosity. The readout rate is currently limited to 1 MHz by the Level 1 trigger. In order to achieve the target integrated luminosity of 50 fb-1 during LHC Run 3, all subdetectors have to be read out by a 40 MHz trigger-less readout system. Especially, the current tracking detectors downstream of the LHCb dipole magnet suffer from large detector dead times and a small granularity in the Outer Tracker, which consists of proportional straw tubes. Therefore, the Downstream Tracker will be replaced by a Scintillating Fibre Tracker with Silicon Photomultiplier readout. The total sensitive area of 340 m2 is made up of 2.5 m long fibre mats consisting of six staggered layers of 250 μm thin scintillating fibres. The scintillation light created by the charged particles traversing the fibre mats is transported to the fibre ends via total internal reflection and detected by state-of-the-art multi-channel SiPM arrays. This paper presents the detector concept, design, challenges, custom-made readout chips, as well as laboratory and beam test results.

    2013-01-01

    Full Text Available The Canadian government designed Indian residential school (IRS system to assimilate Indigenous children into European settler society by dispossessing them of their cultures, languages and traditions. By severing the children’s ties to families and communities, and thus integrating them into Euro-Canadian society, the Crown sought to gain control of Indigenous lands (Miller, 2000. In the schools, which were run by church officials, many children died of neglect and diseases and often faced various other injustices perpetrated by staff, including physical, emotional, cultural, and sexual abuse. (Milloy, 1999. Although the last school was closed in 1996, IRS left behind a devastating legacy characterized by sexual and physical abuse in Indigenous communities, substance abuse, loss of Indigenous languages, over-representation of Indigenous people in correctional facilities, and others. Until recently, these were considered to be private issues. However, the growing body of evidence demonstrates that IRS were responsible for the negative impacts and the government and churches were compelled to recognize the damage done. This article explores Michael Burawoy’s (2005 four types of sociology (policy, critical, professional, and public and assesses the relative contributions of each type in the process of transforming “private troubles” of the IRS legacy into “public issues.” The main thesis of the article is that each type of sociology, with varying degrees of success, promotes the recognition of the injustices inflicted by IRS. The article concludes that Burawoy’s sociology possesses its strengths and weaknesses in identifying private troubles as public issues.Le gouvernement canadien a conçu des pensionnats autochtones (PA pour assimiler les enfants indigènes dans la société des colons européens en les dépossédant de leurs cultures, langues et traditions.

    This note describes the assembly and testing of the 292 petals built for the CMS Tracker End Caps from the beginning of 2005 until the summer of 2006. Due to the large number of petals to be assembled and the need to reach a throughput of 10 to 15 petals per week, a distributed integration approach was chosen. This integration was carried out by the following institutes: I. and III. Physikalisches Institut - RWTH Aachen University; IIHE, ULB \\& VUB Universities, Brussels; Hamburg University; IEKP, Karlsruhe University; FYNU, Louvain University; IPN, Lyon University; and IPHC, Strasbourg University. Despite the large number of petals which needed to be reworked to cope with a late-discovered module issue, the quality of the petals is excellent with less than 0.2\\% bad channels.

  6. Revisiting the Environmental and Socioeconomic Effects of Population Growth: a Fundamental but Fading Issue in Modern Scientific, Public, and Political Circles

    Directory of Open Access Journals (Sweden)

    Camilo Mora

    2014-03-01

    Full Text Available Reversing ongoing declines in human welfare and biodiversity is at the core of human development. Although numerous institutions and avenues are in place to reverse such trends, there seems to be limited consideration of population growth as an ultimate driver. I review recent studies showing how the issue of population growth has been downplayed and trivialized among scientific fields, which may in part account for the reduced public interest in the issue and in turn the limited will for policy action. Different sources of evidence suggest that population growth could fundamentally affect society, nature, and the climate. Although tackling the issue of overpopulation will suffer from major impediments including scientific motivation, public scientific illiteracy, religion, and media attention, ongoing neglect of this issue will increase not only the extent of anthropogenic stressors but also the struggle associated with strategies to reverse biodiversity loss and improve human welfare.

    This paper describes the first demonstrations of two dynamic exit pupil (DEP) tracker techniques for autostereoscopic displays. The first DEP tracker forms an exit pupil pair for a single viewer in a defined space with low intraocular crosstalk using a pair of moving shutter glasses located within the optical system. A display prototype using the first DEP tracker is constructed from a pair of laser projectors, pupil-forming optics, moving shutter glasses at an intermediate pupil plane, an image relay lens, and a Gabor superlens based viewing screen. The left and right eye images are presented time-sequentially to a single viewer and seen as a 3D image without wearing glasses and allows the viewer to move within a region of 40 cm × 20 cm in the lateral plane, and 30 cm along the axial axis. The second DEP optics can move the exit pupil location dynamically in a much larger 3D space by using a custom spatial light modulator (SLM) forming an array of shutters. Simultaneous control of multiple exit pupils in both lateral and axial axes is demonstrated for the first time and provides a viewing volume with an axial extent of 0.6-3 m from the screen and within a lateral viewing angle of ± 20° for multiple viewers. This system has acceptable crosstalk (< 5%) between the stereo image pairs. In this novel version of the display the optical system is used as an advanced dynamic backlight for a liquid crystal display (LCD). This has advantages in terms of overall display size as there is no requirement for an intermediate image, and in image quality. This system has acceptable crosstalk (< 5%) between the stereo image pairs.

    The CMS silicon strip tracker involves about 70 m/sup 2/ of instrumented silicon, with approximately 18500 microstrip detectors read out by 5*10/sup 6/ electronics channels. It has to satisfy a set of stringent requirements imposed by the environment and by the physics expected at the LHC: low cell occupancy and good resolution, radiation hardness aided by adequate cooling, low mass combined with high stability. These conditions have been incorporated in a highly modular design of the detector modules and their support structures, chosen to facilitate construction and to allow for easy assembly and maintenance.

    The tracking system of the CMS detector provides excellent resolution for charged particle tracks and an efficient way of tagging jets. In order to reconstruct good quality tracks, the position and orientation of each silicon pixel and strip modules need to be determined with a precision of several micrometers. The performance of the CMS tracker alignment in 2016 using cosmic-ray data recorded at 0 T magnetic field and proton-proton collision data recorded at 3.8 T magnetic field has been studied. The data-driven validation of the results are presented. The time-dependent movement of the pixel detector's large-scale structure is demonstrated.

    The SuperB asymmetric e{sup +}-e{sup -} collider has been designed to deliver a luminosity greater than 10{sup 36}cm{sup -2}s{sup -1} with moderate beam currents. Comparing to current B-Factories, the reduced center of mass boost of the SuperB machine requires improved vertex resolution to allow precision measurements sensitive to New Physics. We present the conceptual design of the silicon vertex tracker (SVT) for the SuperB detector with the present status of the R and D on the different options under study for its innermost Layer0.

    The ATLAS Transition Radiation Tracker (TRT) is a large straw tube tracking system that is the outermost of the three subsystems of the ATLAS Inner Detector (ID). With over 350,000 readout channels, the TRT provides both excellent particle identification capabilities and electron-pion separation, as well as contributing significantly to the resolution for high-pt tracks in the ID. As the instantaneous luminosity of the LHC increases, the occupancy of the TRT will increase as well. The low-occupancy tracking resolution and efficiency will be presented, as will be studies of resolution and PID at higher occupancies.

    The Outer Tracker (OT) consists of 53 760 straw tubes, covering in total an area of 360 m$^2$. The detector is foreseen to operate under large particle rates, up to 30 kHz/cm per straw in the region closest to the beam. Extensive aging tests conducted earlier on with prototype modules indicated excellent gain stability. In contrast, mass production modules show significant degradation under a rather model level of radiation. This paper presents the observed phenomenon, together with ongoing investigations to both prevent the effect, as well as to recover the gain loss.

    The development of end-use energy consumption and load shape data is important for end-use load forecasting and demand-side management (DSM) planning applications. This paper discusses the objectives, sample design data issues and applications of residential end-use load research and customer survey data at Missouri Public Service (MPS); a combination electric and natural gas utility division of UtiliCorp United Inc. Multiple objectives including rate design, market research, end-use load forecasting and DSM planning, determined that an integrated end-use load research sample design would be the most cost-effective approach. Comprehensive end-use customer survey data was collected and analyzed using XENERGY`s RECAP bill disaggregation program in conjunction with and end-use load research project in 1992 to calibrate EPRI`s REEPS forecasts. The resulting end-use load shapes and UEC`s provide consistent inputs to SRC`s COMPASS model and EPRI`s DSManager model for DSM Planning

    2009-03-01

    Recent public service announcements (PSAs) directed toward Black youth utilize various formats and appeals to stimulate a motivated cognitive process that engenders personal involvement in the HIV/AIDS issue. The Elaboration Likelihood Model (ELM) by Petty and Cacioppo argues that engagement with messages that consist of substantive content causes the audience member to critically analyze the message, which can produce awareness and attitude change. An efficient way to add emphasis to the message and seize the attention of the target audience is to insert the message into an entertainment context. Our study attempted to analyze the impact of the peripheral cue, character appeal, on audience members' attitude change in response to analyzing high- and low-involvement message content. A2 x 4 factorial design was used, with message involvement (high/low) and character appeal (White/Black and celebrity/noncelebrity) as independent variables. The findings showed that celebrity status is the salient factor, with source perception inducing attitude change as a main effect or in an interaction effect with high- and low message content.

    Star tracker is one of the most promising optical attitude measurement devices and it is widely used in spacecraft for its high accuracy. However, how to realize and verify such an accuracy remains a crucial but unsolved issue until now. The authenticity of the accuracy measurement method of a star tracker will eventually determine the satellite performance. A new and robust accuracy measurement method for a star tracker based on the direct astronomical observation is proposed here. In comparison with the conventional method with simulated stars, this method utilizes real navigation stars as observation targets which makes the measurement results more authoritative and authentic. Transformations between different coordinate systems are conducted on the account of the precision movements of the Earth, and the error curves of directional vectors are obtained along the three axes. Based on error analysis and accuracy definitions, a three-axis accuracy evaluation criterion has been proposed in this paper, which could determine pointing and rolling accuracy of a star tracker directly. Experimental measurements confirm that this method is effective and convenient to implement. Such a measurement environment is close to the in-orbit conditions and it can satisfy the stringent requirement for high-accuracy star trackers. PMID:26948412

    The precision of an eye-tracker is critical to the correct identification of eye movements and their properties. To measure a system's precision, artificial eyes (AEs) are often used, to exclude eye movements influencing the measurements. A possible issue, however, is that it is virtually impossible to construct AEs with sufficient complexity to fully represent the human eye. To examine the consequences of this limitation, we tested currently used AEs from three manufacturers of eye-trackers and compared them to a more complex model, using 12 commercial eye-trackers. Because precision can be measured in various ways, we compared different metrics in the spatial domain and analyzed the power-spectral densities in the frequency domain. To assess how precision measurements compare in artificial and human eyes, we also measured precision using human recordings on the same eye-trackers. Our results show that the modified eye model presented can cope with all eye-trackers tested and acts as a promising candidate for further development of a set of AEs with varying pupil size and pupil-iris contrast. The spectral analysis of both the AE and human data revealed that human eye data have different frequencies that likely reflect the physiological characteristics of human eye movements. We also report the effects of sample selection methods for precision calculations. This study is part of the EMRA/COGAIN Eye Data Quality Standardization Project.

    The pieces of the Tracker that will be operated in the forthcoming Magnet Test and Cosmic Challenge (MTCC) have been transported inside the dummy tracker support tube to the CMS experimental hall (Point 5, Cessy). The operation took place during the night of 12th May, covering the ~15km distance in about three hours. The transport was monitored for shocks, temperature and humidity with the help of the CERN TS-IC section. The Tracker setup comprises segments of the Tracker Inner Barrel (TIB), the Tracker Outer Barrel (TOB) and Tracker EndCaps (TEC) detectors. It represents roughly 1% of the final CMS Tracker. Installation into the solenoid is foreseen to take place on Wednesday 17th May.

  2. The LHCb Upgrade Scintillating Fibre Tracker

    2014-01-01

    The Scintillating Fibre (SciFi) Tracker is designed to replace the current downstream tracking detectors in the LHCb Upgrade during 2018 (CERN/LHCC 2014-001; LHCb TDR 15). The operation and the results obtained from the data collected 2011 and 2012 demonstrate that the current detector is robust and functioning very well. However, the limit of O ( 1 fb-1) of data per year cannot be overcome without improving the detector. This will be achieved using 25 ns bunch spacing with the average number of proton-proton interactions per bunch crossing n = 7 : 6. Collecting data at this luminosity will only be possible if the detector is improved by increasing the readout of the front-end electronics to 40MHz and implementing a more flexible software-based triggering system that will increase the data rate as well as the efficiency. The increase in interactions per bunch crossing will result in an increased occupancy in the tracking detectors and will exceed the operational occupancy for the Outer Tracker. Here we presen...

  3. The Upgrade of the CMS Outer Tracker

    CERN Document Server

    Steinbrueck, Georg

    2014-01-01

    During the high luminosity phase of the LHC starting around 2025 (HL-LHC), the machine is expected to deliver an instantaneous luminosity of $5\\cdot10^{34}$~cm$^{-2}$s$^{-1}$. A total of 3000~fb$^{-1}$ of data is foreseen to be delivered, hereby increasing the physics potential of the LHC experiments significantly. However, this fivefold increase in luminosity compared to the design luminosity of the LHC will lead to a higher track multiplicity in the silicon tracking detectors of the experiments, and to severe radiation levels. In order to maintain physics capability, CMS will build a completely new tracking detector comprising a pixel detector and an outer tracker. Furthermore, information from the outer tracker will be used in the first level trigger of CMS to ensure a sufficient trigger rejection. For this purpose, CMS will use so-called p$_{T}$ modules which will provide a momentum measurement at the module level. These modules consist of two back-to-back strip sensors for the outer layers, and a st...

    The next LHC runs, with a significant increase in instantaneous luminosity, will provide a big challenge for the trigger and data acquisition systems of all the experiments. An intensive use of the tracking information at the trigger level will be important to keep high efficiency for interesting events despite the increase in multiple collisions per bunch crossing. In order to increase the use of tracks within the High Level Trigger, the ATLAS experiment planned the installation of a hardware processor dedicated to tracking: the Fast TracKer processor. The Fast Tracker is designed to perform full scan track reconstruction of every event accepted by the ATLAS first level hardware trigger. To achieve this goal the system uses a parallel architecture, with algorithms designed to exploit the computing power of custom Associative Memory chips, and modern field programmable gate arrays. The processor will provide computing power to reconstruct tracks with transverse momentum greater than 1 GeV in the whol...

    2004-01-01

    The ATLAS SemiConductor Tracker (SCT) is presented. About 16000 silicon micro-strip sensors with a total active surface of over 60 m /sup 2/ and with 6.3 million read-out channels are built into 4088 modules arranged into four barrel layers and nine disks covering each of the forward regions up to an eta of 2.5. Challenges are imposed by the hostile radiation environment with particle fluences up to 2*10 /sup 14/ cm/sup -2/ 1 MeV neutron NIEL equivalent and 100 kGy TID, the 25 ns LHC bunch crossing time and the need for a hermetic, lightweight tracker. The solution adopted is carefully designed strip detectors operated at -7 degrees C, biased up to 500 V and read out by binary rad-hard fast BiCMOS electronics. A zero-CTE carbon fibre structure provides mechanical support. 30 kW of power are supplied on aluminium/Kapton tapes and cooled by C/sub 3/F/sub 8/ evaporative cooling. Data and commands are transferred by optical links. Prototypes of detector modules have been built, irradiated to the maximum expected ...

    The SemiConductor Tracker (SCT), comprising of silicon micro-strip detectors is one of the key precision tracking devices in the ATLAS Inner Detector. ATLAS is one of the experiments at CERN LHC. The completed SCT is in very good shapes with 99.3% of the SCT’s 4088 modules (a total of 6.3 million strips) are operational. The noise occupancy and hit efficiency exceed the design specifications. In the talk the current status of the SCT will be reviewed. We will report on the operation of the detector, its performance and observed problems, with stress on the sensor and electronics performance. In December 2009 the ATLAS experiment at the CERN Large Hadron Collider (LHC) recorded the first proton-proton collisions at a centre-of-mass energy of 900 GeV and this was followed by the unprecedented energy of 7 TeV in March 2010. The Semi-Conductor Tracker (SCT) is the key precision tracking device in ATLAS, made from silicon micro-strip detectors processed in the planar p-in-n technology. The signals from the strip...

    2010-01-01

    The LHCb experiment at the Large Hadron Collider studies the decay of B mesons to test the description of CP violation in the Standard Model and to search for new physics. The decay $B_s \\to \\mu^+ \\mu^-$ has been identified as very promising in the search for new physics. An excellent invariant mass resolution is required to suppress backgrounds to this decay. This in turn requires a momentum resolution of dp/p = 0.4%. The Outer Tracker is part of the LHCb tracking system and has been commissioned with cosmic muons. The noise in the Outer Tracker is shown to be less than 0.05%. To use drift time information in the reconstruction of cosmic tracks, the event time must be known. Four methods to obtain the event time are studied and compared. It is shown that the event time can be obtained with a resolution better than 2.6 ns. Using drift time information, tracks are reconstructed with a resolution of 344 $\\mu$m. Knowledge of the event time enables the calibration of electronic time offsets and the r(t)– relati...

    Time-lapse experiments play a key role in studying the dynamic behavior of cells. Single-cell tracking is one of the fundamental tools for such analyses. The vast majority of the recently introduced cell tracking methods are limited to fluorescently labeled cells. An equally important limitation is that most software cannot be effectively used by biologists without reasonable expertise in image processing. Here we present CellTracker, a user-friendly open-source software tool for tracking cells imaged with various imaging modalities, including fluorescent, phase contrast and differential interference contrast (DIC) techniques. CellTracker is written in MATLAB (The MathWorks, Inc., USA). It works with Windows, Macintosh and UNIX-based systems. Source code and graphical user interface (GUI) are freely available at: http://celltracker.website/ horvath.peter@brc.mta.hu Supplementary data are available at Bioinformatics online. © The Author 2015.

    Masetti, Lorenzo; Shah, S Y; Stringer, Robert

    2009-01-01

    The CMS Silicon Strip Tracker Detector Control System is a distributed software which ensures the safe and coherent operation of the detector, by controlling approximate to 2000 power supplies for the silicon modules and by monitoring-more than 1000 environmental sensors. In this paper we first present the architecture of the control system and the characteristics of the controlled hardware, then we discuss some general strategies adopted in the implementation. We propose a method to give an effective representation for the state of a large but homogeneous system, stressing the necessity to provide the user with some quantitative information and presenting an effective algorithm to keep this information updated in real time. We also present the advantages of a new approach for the automatic analysis and recovery from error conditions via a wizard that relieves the experts from unnecessary and time-wasting work. The tracker was chosen as a use-case in a framework for automatic 3D GUI prototyping: some prelimin...

    Tracker After more than 3 years of successful operation at the LHC, we report on the operation and performance of the Semi-Conductor Tracker (SCT) functioning in a high luminosity, high radiation environment. The SCT is part of the ATLAS experiment at CERN and is constructed of 4088 silicon detector modules for a total of 6.3 million strips. Each module is designed, constructed and tested to operate as a stand-alone unit, mechanically, electrically, optically and thermally. The modules are mounted into two types of structures: one barrel (4 cylinders) and two end-cap systems (9 disks on each end of the barrel). The SCT silicon micro-strip sensors are processed in the planar p-in-n technology. The signals are processed in the front-end ABCD3TA ASICs, which use a binary readout architecture. Data is transferred to the off-detector readout electronics via optical fibers. We find 99.3% of the SCT modules are operational, noise occupancy and hit efficiency exceed the design specifications; the alignment is very cl...

    The GigaTracker is a hybrid silicon pixel detector built for the NA62 experiment aiming at measuring the branching fraction of the ultra-rare kaon decay K+→π+νν¯ at the CERN SPS. The detector has to track particles in a beam with a flux reaching 1.3 MHz/mm2 and provide single-hit timing with 200 ps RMS resolution for a total material budget of less than 0.5% X0 per station. The tracker comprises three 60.8 mm×27 mm stations installed in vacuum (∼10$^{−6}$mbar) and cooled with liquid C6F14 circulating through micro-channels etched inside a few hundred micron thick silicon plates. Each station is composed of a 200 μm thick silicon sensor read out by 2×5 custom 100 μm thick ASICs, called TDCPix. Each chip contains 40×45 asynchronous pixels, 300 μm×300 μm each and is instrumented with 100 ps bin time-to-digital converters. In order to cope with the high rate, the TDCPix is equipped with four 3.2 Gb/s serialisers sending out the data. We will describe the detector and the results from the 2014 an...

    The extended use of tracking information at the trigger level in the LHC is crucial for the trigger and data acquisition (TDAQ) system to fulfill its task. Precise and fast tracking is important to identify specific decay products of the Higgs boson or new phenomena, as well as to distinguish the contributions coming from the many collisions that occur at every bunch crossing. However, track reconstruction is among the most demanding tasks performed by the TDAQ computing farm; in fact, complete reconstruction at full Level-1 trigger accept rate (100 kHz) is not possible. In order to overcome this limitation, the ATLAS experiment is planning the installation of a dedicated processor, the Fast Tracker (FTK), which is aimed at achieving this goal. The FTK is a pipeline of high performance electronics, based on custom and commercial devices, which is expected to reconstruct, with high resolution, the trajectories of charged-particle tracks with a transverse momentum above 1 GeV, using the ATLAS inner tracker info...

  14. Modeling of intensified high dynamic star tracker.

    Science.gov (United States)

    Yan, Jinyun; Jiang, Jie; Zhang, Guangjun

    2017-01-23

    An intensified high dynamic star tracker (IHDST) is a photoelectric instrument and stably outputs three-axis attitude for a spacecraft at very high angular velocity. The IHDST uses an image intensifier to multiply the incident starlight. Thus, high sensitivity of the star detection is achieved under short exposure time such that extremely high dynamic performance is achieved. The IHDST differs from a traditional star tracker in terms of the imaging process. Therefore, we establish a quantum transfer model of IHDST based on stochastic process theory. By this model, the probability distribution of the output quantum number is obtained accurately. Then, we introduce two-dimensional Lorentz functions to describe the spatial spreading process of the IHDST. Considering the interaction of these two processes, a complete star imaging model of IHDST is provided. Using this model, the centroiding accuracy of the IHDST is analyzed in detail. Accordingly, a working parameter optimizing strategy is developed for high centroiding accuracy and improved dynamic performance. Finally, the laboratory tests and the night sky experiment support the conclusions.

    1996-02-01

    In this paper the description of the Solar Correlation Tracker prototype built by the Instituto de Astrof isica de Canarias is presented. The system is mainly conceived as a solar image tranquilizer, although a scanning utility has also been included in order to displace the image on the final focal plane with sub-arcsecond steps, thus allowing to perform two-dimensional high spatial resolution spectroscopy. The behaviour of the different elements of the tracker is shown, as well as their influence in the performance of the system. The restrictions of the Absolute Differences algorithm, used to detect image motion when granulation fields are considered, are extensively discussed. Laboratory and telescope tests have demonstrated the capabilities of the system. The electronic components have been adapted to new optics and mechanics developed at the Kiepenheuer Institut to build an Advanced Solar Correlation Tracker. The final version of the system has been installed at the German VTT of the Spanish Observatorio del Teide. The tests carried out have demonstrated that a bandwidth of about 60Hz (for an attenuation factor of two) is achieved, which is approximately four times larger than that of previous Correlation Trackers, at the same level of attenuation.

    2014-12-01

    A team of educators, scientists, and communication experts from multiple universities as well as a Science museum will report on the impact of ScienceToGo.org, which is an Out of Home Multi-Media (OHMM) exhibit targeting adults riding a major subway system. The campaign's goal is to design, implement, and study the efficacy of an OHMM model for free choice science learning about our changing climate. Subway riders represent a diverse and captive audience with most of them spending an average of one hour a day in the subway system. Through the use of specially designed OHMM such as train placards, platform posters, and virtual resources the campaign engages a potential audience of 500,000 riders/day with opportunities to learn climate change science informally. The primary goal of the ScienceToGo.org campaign is to engage, entertain, and educate the adult subway riding community in major U.S. city about climate change as a real, relevant, and solvable local challenge. A naturalistic quasi-experimental inquiry employing a mixed methodology approach best describes our research design with half of the subway system exposed to the project signage (experimental group) and the other half not being exposed to the project signage (control group). To identify possible outcomes, data was collected in the several forms: survey, analytic data associated with website, social media, web app, focus groups, and observations. This campaign is an example of how an individual's daily routine may be enhanced with an informal science learning opportunity. We see an urgent need to improve both the public's engagement with climate change science and to the profile of climate change science in formal education settings. The campaign makes deliberate use of humor and fun to engage a public and diverse audience with the serious issue of climate change. The research that will be presented will reveal some of the strengths and weaknesses of this strategy when communicating science to a diverse

  2. Mainstream Issues of Education and Public Awareness of Space Activities and Sciences among universities and Scientific Institutes.

    Science.gov (United States)

    Singh, Balbir

    This paper is an effort to study and analyze several constraints and issues of space technology and education that organizations other than governmental organizations face in awareness program. In recent years, advancements in technologies have made it possible for Volunteer and Technical Communities, non-government organizations, private agencies and academic research institutions to provide increasing support to space education management and emphasis on response efforts. Important cornerstones of this effort and support are the possibility to access and take advantage of satellite imagery as well as the use of other space-based technologies such as telecommunications satellites and global navigation satellite systems included in main curriculum plus the implementation of programs for use of high class sophisticated technologies used by industries to the students and researchers of non-space faring nations. The authors recognize the importance of such new methodologies for education and public Awareness. This paper demonstrates many hurdles universities and scientific institutions face including lack of access in terms of financial and technical resources for better support. A new model for coordinated private sector partnership in response to space sciences and education has been discussed. In depth analysis and techniques need to connect these pioneering communities with the space industry as well as the space governmental agencies, with special emphasis on financial constraints. The paper mandates its role to promote the use of space-based information; its established networks bringing together national institutions responsible for these space based activities, as well as other end users, and space solution experts; and its technical foundation, particularly in the area of information technologies. To help building a tighter cooperation and further understanding among all these communities, paper delivers an intensive report and solutions for future

    The CMS silicon tracker is the largest silicon detector ever built. It consists of an inner pixel detector, with 66 million readout channels, and an outer 200 m$^{2}$ silicon strip detector with 10 million channels. The successful operation of this detector during the first three years of LHC running with proton-proton and heavy ion collisions is discussed. Results include operational challenges encountered during data taking that influenced the active fraction and readout efficiency of the detectors. Details are given on the performance at high occupancy with respect to local observables, such as signal-to-noise ratio and hit reconstruction efficiency, and on radiation effects with respect to the evolution of power consumption, sensor bias, readout thresholds and leakage current.

    In this paper, we report high-precision absolute distance and vibration measurements performed with frequency scanned interferometry. Absolute distance was determined by counting the interference fringes produced while scanning the laser frequency. High-finesse Fabry-Perot interferometers were used to determine frequency changes during scanning. A dual-laser scanning technique was used to cancel drift errors to improve the absolute distance measurement precision. A new dual-channel FSI demonstration system is also presented which is an interim stage toward practical application of multi-channel distance measurement. Under realistic conditions, a precision of 0.3 microns was achieved for an absolute distance of 0.57 meters. A possible optical alignment system for a silicon tracker is also presented.

    This paper presents results on the radiation hardness of the LHCb Outer Tracker (OT) during LHC operation in 2010 and 2011. Modules of the OT have shown to suffer from ageing effects that lead to gain loss, after irradiation in the laboratory. Under irradiation at moderate intensities an insulating layer is formed on the anode wire of the OT straw cells. This ageing effect is caused by contamination of the counting gas due to outgassing of the glue used in the construction of the OT modules. Two methods to monitor gain stability in the OT are presented: module scans with radioactive sources and the study of hit efficiency as a function of amplifier threshold. No gain loss is observed after receiving 1.3 fb{sup -1} of integrated luminosity corresponding to an integrated charge of 0.055 C/cm in the hottest spot of the detector.

    This document proposes an early, high level design for a fitness tracking system which can automatically log weight lifting style workouts. The system will provide an easy to use interface both physically through the use of several wireless wristband style motion trackers worn on the limbs, and graphically through a smartphone application. Exercise classification will be accomplished by calibration of the user’s specific motions. The system will accurately track a user’s workout, miscounting no more than one repetition in every 20, have sufficient battery life to last several hours, work with existing smartphones and have a cost similar to those of current fitness tracking devices. This document presents the mission background, current state-of-theart, stakeholders and their expectations, the proposed system’s context and concepts, implementation concepts, system requirements, first sublevel function decomposition, possible risks for the system, and a reflection on the design process.

  7. The Alignment of the CMS Silicon Tracker

    CERN Document Server

    Lampen, Pekka Tapio

    2013-01-01

    The CMS all-silicon tracker consists of 16588 modules, embedded in a solenoidal magnet providing a field of B = 3.8 T. The targeted performance requires that the alignment determines the module positions with a precision of a few micrometers. Ultimate local precision is reached by the determination of sensor curvatures, challenging the algorithms to determine about 200k parameters simultaneously, as is feasible with the Millepede II program. The main remaining challenge are global distortions that systematically bias the track parameters and thus physics measurements. They are controlled by adding further information into the alignment workflow, e.g. the mass of decaying resonances or track data taken with B = 0 T. To make use of the latter and also to integrate the determination of the Lorentz angle into the alignment procedure, the alignment framework has been extended to treat position sensitive calibration parameters. This is relevant since due to the increased LHC luminosity in 2012, the Lorentz angle ex...

    The LHC survey laser tracker control system is based on an industrial software package (Axyz) from Leica Geosystems™ that has an interface to Visual Basic™, which we used to automate the geometric measurements for the LHC magnets. With the new version of the Leica software, this Visual Basic™ interface is no longerb available and we had to redesign the interface software to adapt to a PC-DMIS server that replaced the Axyz software. As this package is no longer supported, we have taken the decision to recode the automation application in LabVIEW. This presentation describes the existing equipment, interface and application showing the reasons for our decisions to move to PC-DMIS and LabVIEW. A comparison between the new and legacy system is made

    In the last 30 years numerous attempts have been made to improve the efficiency of the parabolic collectors in the electric power production, although most of the studies have focused on the industrial production of thermoelectric power. This research focuses on the application of this concentrating solar thermal power in the unexplored field of building construction. To that end, a mechatronic prototype of a hybrid paraboloidal and cylindrical-parabolic tracker based on the Arduido technology has been designed. The prototype is able to measure meteorological data autonomously in order to quantify the energy potential of any location. In this way, it is possible to reliably model real commercial equipment behavior before its deployment in buildings and single family houses.

    2010-07-01

    Tokai to Kamioka (T2K) is a new generation neutrino oscillation experiment that started collecting data in 2009 in Japan. A {nu}{mu} beam produced by an intense proton beam colliding onto a target is directed from J-PARC (Tokai) to the 50 kt water Cerenkov detector Super Kamiokande at a distance of 295 km. T2K's main goals are measuring one of the last unknown parameters of the PMNS matrix {Theta}{sub 13} by using {nu}e appearance in the beam, and measuring precisely {Delta}m{sup 2}23 and {Theta}{sub 23} by using {nu}{mu} disappearance. A near detector (ND280) placed in a 0.2 T magnetic field is located at 280 m from the target to allow the characterisation of the neutrino beam before oscillation. In particular, the detector measures the neutrino energy spectra, beam flavor composition, background and cross-sections. ND280 started taking data at the end of 2009. An essential element of ND280 is the tracker, composed of two fine grained detectors (FGD) to serve as targets for neutrino interactions and measure cross-sections, and three time projection chambers (TPC) to track and identify charged particles. The TPCs' readout planes are equipped with Micromegas micro-pattern detectors, achieving a total active surface of 9 m{sup 2}. The first FGD is made of scintillator bars only whereas the second one includes water targets. The performance of the tracker with cosmic ray and neutrino data will be presented. (author)

    The STAR Collaboration proposes to construct a state-of-the-art microvertex detector,the Heavy Flavor Tracker (HFT), utilizing active pixel sensors and silicon strip technology. The HFT will significantly extend the physics reach of the STAR experiment for precision measurement of the yields and spectra of particles containing heavy quarks. This will be accomplished through topological identification of D mesons by reconstruction of their displaced decay vertices with a precision of approximately 50 mu m in p+p, d+A, and A+A collisions. The HFT consists of 4 layers of silicon detectors grouped into two sub-systems with different technologies, guaranteeing increasing resolution when tracking from the TPC and the Silicon Strip Detector (SSD) towards the vertex of the collision. The Intermediate Silicon Tracker (IST), consisting of two layers of single-sided strips, is located inside the SSD. Two layers of Silicon Pixel Detector (PIXEL) are inside the IST. The PIXEL detectors have the resolution necessary for a precision measurement of the displaced vertex. The PIXEL detector will use CMOS Active Pixel Sensors (APS), an innovative technology never used before in a collider experiment. The APSsensors are only 50 mu m thick and at a distance of only 2.5 cm from the interaction point. This opens up a new realm of possibilities for physics measurements. In particular, a thin detector (0.28percent radiation length per layer) in STAR makes it possible to do the direct topological reconstruction of open charm hadrons down to very low pT by the identification of the charged daughters of the hadronic decay.

    Foton HC Systems has developed a new CPV tracker model, specially focused on its tracking efficiency and the effect of the tracker control techniques on the final energy yield of the system. This paper presents the theoretical work carried out into determining the energy yield for a CPV system, and illustrates the steps involved in calculating and understanding how energy consumption for tracking is opposed to tracker pointing errors. Additionally, the expressions to compute the optimum parameters are presented and discussed.

  17. Lighting for the human circadian clock: recent research indicates that lighting has become a public health issue.

    Science.gov (United States)

    Pauley, Stephen M

    2004-01-01

    The hypothesis that the suppression of melatonin (MLT) by exposure to light at night (LAN) may be one reason for the higher rates of breast and colorectal cancers in the developed world deserves more attention. The literature supports raising this subject for awareness as a growing public health issue. Evidence now exists that indirectly links exposures to LAN to human breast and colorectal cancers in shift workers. The hypothesis begs an even larger question: has medical science overlooked the suppression of MLT by LAN as a contributor to the overall incidence of cancer? The indirect linkage of breast cancer to LAN is further supported by laboratory rat experiments by David E. Blask and colleagues. Experiments involved the implanting of human MCF-7 breast cancer cell xenografts into the groins of rats and measurements were made of cancer cell growth rates, the uptake of linoleic acid (LA), and MLT levels. One group of implanted rats were placed in light-dark (12L:12D) and a second group in light-light (12L:12L) environments. Constant light suppressed MLT, increased cancer cell growth rates, and increased LA uptake into cancer cells. The opposite was seen in the light-dark group. The proposed mechanism is the suppression of nocturnal MLT by exposure to LAN and subsequent lack of protection by MLT on cancer cell receptor sites which allows the uptake of LA which in turn enhances the growth of cancer cells. MLT is a protective, oncostatic hormone and strong antioxidant having evolved in all plants and animals over the millennia. In vertebrates, MLT is normally produced by the pineal gland during the early morning hours of darkness, even in nocturnal animals, and is suppressed by exposure to LAN. Daily entrainment of the human circadian clock is important for good human health. These studies suggest that the proper use and color of indoor and outdoor lighting is important to the health of both humans and ecosystems. Lighting fixtures should be designed to minimize

    Baggenstoss, Paul M

    2015-05-01

    This paper describes a tracker specially designed to track clicking beaked whales using widely spaced bottom-mounted hydrophones, although it can be adapted to different species and sensors. The input to the tracker is a sequence of static localization solutions obtained using time difference of arrival information at widely spaced hydrophones. To effectively handle input localizations with high ambiguity, the tracker is based on multi-hypothesis tracker concepts, so it considers all potential association hypotheses and keeps a large number of potential tracks in memory. The method is demonstrated on actual data and shown to successfully track multiple beaked whales at depth.

    2016-01-01

    Foundational elements of problem based learning (PBL) are triggers, tutors and students. Ineffective triggers are important issues for students' inability to generate appropriate learning issues. The objective of this study was to evaluate PBL triggers and to determine similarities of students' generated learning issues with predetermined faculty objectives. It was a retrospective study conducted in 2014 analyzing all 24 PBL-triggers used at Centre for Foundation Studies, International Islamic University Malaysia, in four semesters during two consecutive years 2011 and 2012. Triggers were used as textual and illustration format equally in each semester. Total 16 PBL-triggers with highest and lowest achieving similarities of learning issues with predetermined faculty objectives were selected equally from each semester and format. The trigger quality and learning issues related to predetermine faculty objectives were analyzed and presented as mean and percent distribution. Mean similarities score of students' generated learning issues were 3.4 over 5 predetermined faculty objectives which was 68%, varied from 58% to 79%. More than 70% similarities were generated from five textual and four illustrated triggers, while PBL, it is the designing considering influential variables that influence higher outcomes. Triggers should have planned clues that lead students to generate issues correlate with faculty objectives. Educational institution should emphasize on training needs of faculty at regular interval to develop and re-in force teachers' skills in trigger design, thereby to promote a sustainable educational and organizational development.

    Bloch, Christoph; Abbaneo, Duccio; Fabjan, Christian Wolfgang

    2008-01-01

    In 2008 the Large Hardon Collider (LHC) at CERN will start producing proton-proton collisions of unprecedented energy. One of its main experiments is the Compact Muon Solenoid (CMS), a general purpose detector, optimized for the search of the Higgs boson and super symmetric particles. The discovery potential of the CMS detector relies on a high precision tracking system, made of a pixel detector and the largest silicon strip Tracker ever built. In order to operate successfully a device as complex as the CMS silicon strip Tracker, and to fully exploit its potential, the properties of the hardware need to be characterized as precisely as possible, and the reconstruction software needs to be commissioned with physics signals. A number of issues were identified and studied to commission the detector, some of which concern the entire Tracker, while some are specific to the Tracker Outer Barrel (TOB): - the time evolution of the signals in the readout electronics need to be precisely measured and correctly simulate...

  7. Climate Action Tracker Update. Climate Shuffle

    2011-11-15

    The Climate Action Tracker (CAT) compares and assesses national and global action against a range of different climate targets across all relevant time frames, starting with an ongoing analysis of countries' current emission reduction pledges. National action on climate change mitigation appears to be joining the international climate negotiations in the new and ever popular 'climate shuffle' dance. It involves maximum effort and motion while staying in the same spot, or even, in some cases, going backwards. Recent emissions trends and estimates of the effects of those policies in place and proposed lead to a new estimate that warming is likely to approach 4C by 2100, significantly above the warming that would result from full implementation of the pledges (3.3C). The continuous global fossil-fuel intensive development of the past decade suggests that high warming levels of 4C are more plausible than assuming full implementation of current pledges. Evidence is ever increasing that existing and planned policies are not sufficient for countries to meet these pledges.

  8. 3D Monitoring of LHCb Inner Tracker

    CERN Multimedia

    Sainvitu, Pascal

    2015-01-01

    The positions of the Inner Tracker (IT) detectors of the LHCb experiment installed in the LHC at CERN are impacted by the LHCb dipole magnet powering. In the past the movements of the stations have been measured using standard survey methods during magnet tests in shutdown periods. But the survey targets are visible only in very narrow spaces and the access to the IT is very difficult, even impossible in the central region when the detector is closed. Finally the precision of the standard survey measurement is affected by the poor configuration. In 2013 and 2014, during the first long shutdown of the LHC (LS1), the CERN Survey team (EN/MEF-SU) in collaboration with the LHCb Technical Coordination and the EPFL (Ecole Polytechnique Fédérale de LAUSANNE, CH), developed a permanent monitoring system which has been tested and installed in order to allow the 3D position measurement of the IT stations, even during the run periods, with a precision of 100 microns at 1 sigma level. The 3D Monitoring system of the LH...

    2011-01-01

    The Semi-Conductor Tracker (SCT), is a silicon strip detector and one of the key precision tracking devices in the Inner Detector of the ATLAS experiment at CERN LHC. The SCT is constructed of 4088 silicon detector modules for a total of 6.3 million strips. Each module is designed, constructed and tested to operate as a stand-alone unit, mechanically, electrically, optically and thermally. The modules are mounted into two macro-structures: one barrel and two end-cap. The SCT silicon micro-strip sensors are processed in the planar p-in-n technology. The signals from the strips are processed in the front-end ASICS ABCD3TA, working in the binary readout mode. Data is transferred to the off-detector readout electronics via optical fibers. The completed SCT has been installed inside the ATLAS experimental cavern since 2007 and has been operational since then. Calibration data has been taken regularly and analyzed to determine the noise performance of the system. Extensive commissioning with cosmic ray events has b...

    Situated at the LHC, the LHCb experiment is to measure B meson decay with high statistics. Its primary goals are the establishment of CP violation parameters with high precision, and the study of rare B meson decays to look for physics processes beyond the Standard Model. In this thesis, an overview is given on the Outer Tracker (OT) subdetector of the LHCb experiment. The requirements on efficiency, resolution, occupancy and radiation hardness are discussed. The detector design and readout electronics of the OT, a gas filled detector, are presented. To meet the requirements, straw tube cathodes of 4.9mm inner diameter surround the anode wires. The tubes are filled with an Argon based counting gas at atmospheric pressure, allowing for a channel resolution better then 200mum. To limit multiple scattering, the OT is built from lightweight composite materials, resulting in a momentum resolution of dp/p < 0.6% for p between 0 and 150 GeV/c. From extensive ageing tests involving single channels as well as entir...

    The optical alignment of the star trackers on the Global Precipitation Measurement (GPM) core spacecraft at NASA Goddard Space Flight Center (GSFC) was challenging due to the layout and structural design of the GPM Lower Bus Structure (LBS) in which the star trackers are mounted as well as the presence of the star tracker shades that blocked line-of-sight to the primary star tracker optical references. The initial solution was to negotiate minor changes in the original LBS design to allow for the installation of a removable item of ground support equipment (GSE) that could be installed whenever measurements of the star tracker optical references were needed. However, this GSE could only be used to measure secondary optical reference cube faces not used by the star tracker vendor to obtain the relationship information and matrix transformations necessary to determine star tracker alignment. Unfortunately, due to unexpectedly large orthogonality errors between the measured secondary adjacent cube faces and the lack of cube calibration data, we required a method that could be used to measure the same reference cube faces as originally measured by the vendor. We describe an alternative technique to theodolite autocollimation for measurement of an optical reference mirror pointing direction when normal incidence measurements are not possible. This technique was used to successfully align the GPM star trackers and has been used on a number of other NASA flight projects. We also discuss alignment theory as well as a GSFC-developed theodolite data analysis package used to analyze angular metrology data.

    Full Text Available The Spanish Crown not only made short term loans frommajor international bankers, it also borrowed by issuing long term bonds called «juros», which were bought by Spanish and foreign investors. The issue of such public debt instruments was particularly intense in the 16th and 17th centuries in order to finance the Spanish Crown’s ambitious foreign policy. This paper studies the «juros» issued on Murcia’s «alcabalas » using a data base with all their bonds issued on this tax and city. Theresearch tries to obtain a picture as clear as possible of the supply and demand of «juros» during that period. We were able to observe a growth in the number of «juros», changes in the average value of their annual rents and the decline of the interest rates paid over time. It shows the development of a market for public debt in Castile.

    Wristband activity trackers have become widely used among young adults. However, few studies have explored their use for monitoring and improving health outcomes among older adults. The purpose of this study was to evaluate the feasibility and utility of activity tracker use among older adults for monitoring activity, improving self-efficacy, and health outcomes. A 12-week pilot study was conducted to evaluate the feasibility and utility of mobile wristband activity trackers. The sample (N = 34) was 65% women 73.5 ± 9.4 years of age who had a high school diploma or GED (38%) and reported an income ≤$35,000 (58%). Participants completing the study (95%) experienced a decrease in waist circumference (p > 0.009), however no change in self-efficacy. Participants found activity trackers easy to use which contributed to minimal study withdrawals. It was concluded that activity trackers could be useful for monitoring and promoting physical activity and improving older adults' health.

    2013-07-01

    We are working on the development of the beam detector for experiments with pion beams at HADES spectrometer in GSI Darmstadt. Pions are created impacting nitrogen or proton beams on a secondary beryllium target and are then delivered through a chicane to the experimental areas. The expected momentum spread of the secondary pion beam is about 8 % and the main goal of this beam detector is to deliver information about the pion momentum for each beam particle. The challenging issue is to achieve an accurate measurement (∼ % fj) of each pion in a high intensity (10{sup 8} part./spill) environment along the pion-bean chicane. This translates into a rate of 10{sup 6} pion/spill with a kinetic energy of 1-2 GeV at the HADES target point. We are currently testing a tracker system, based on double-sided silicon strips detectors with higher radiation hardness and n-XYTER ASIC readout. For prototyping we have prepared the acquisition system compatible with the CBM data acquisition system, for the future employment with HADES we are currently working on acquisition based on the novel TRB3 board. In this talk we are showing current status and performance of the system, and recent results obtained in the laboratory and with proton beams.

    To enable the Hobby-Eberly Telescope Dark Energy Experiment, The University of Texas at Austin Center for Electromechanics and McDonald Observatory developed a precision tracker and control system - an 18,000 kg robot to position a 3,100 kg payload within 10 microns of a desired dynamic track. Performance requirements to meet science needs and safety requirements that emerged from detailed Failure Modes and Effects Analysis resulted in a system of 13 precision controlled actuators and 100 additional analog and digital devices (primarily sensors and safety limit switches). Due to this complexity, demanding accuracy requirements, and stringent safety requirements, two independent control systems were developed. First, a versatile and easily configurable centralized control system that links with modeling and simulation tools during the hardware and software design process was deemed essential for normal operation including motion control. A second, parallel, control system, the Hardware Fault Controller (HFC) provides independent monitoring and fault control through a dedicated microcontroller to force a safe, controlled shutdown of the entire system in the event a fault is detected. Motion controls were developed in a Matlab-Simulink simulation environment, and coupled with dSPACE controller hardware. The dSPACE real-time operating system collects sensor information; motor commands are transmitted over a PROFIBUS network to servo amplifiers and drive motor status is received over the same network. To interface the dSPACE controller directly to absolute Heidenhain sensors with EnDat 2.2 protocol, a custom communication board was developed. This paper covers details of operational control software, the HFC, algorithms, tuning, debugging, testing, and lessons learned.

  11. Addressing health care market reform through an insurance exchange: essential policy components, the public plan option, and other issues to consider.

    HEALTH INSURANCE EXCHANGE: This Issue Brief examines issues related to managed competition and the use of a health insurance exchange for the purpose of addressing cost, quality, and access to health care services. It discusses issues that must be addressed when designing an exchange in order to reform the health insurance market and also examines state efforts at health reform that use an exchange. RISK VS. PRICE COMPETITION: The basic component of managed competition is the creation an organized marketplace that brings together health insurers and consumers (either as individuals or through their employers). The sponsor of the exchange would set "rules of engagement" for participating insurers and offer consumers a menu of choices among different plans. Ultimately, the goal of a health insurance exchange is to shift the market from competition based on risk to competition based on price and quality. ADVERSE SELECTION AND AFFORDABILITY: Among the issues that need to be addressed if an exchange that uses managed competition has a realistic chance of reducing costs, improving quality, and expanding coverage: Everyone needs to be in the risk pool, with individuals required to purchase insurance or face significant financial consequences; effective risk adjustment is essential to eliminate risk selection as an insurance business model--forcing competition on costs and quality; the insurance benefit must be specific and clear--without standards governing cost sharing, covered services, and network coverage there is no way to assess whether a requirement to purchase or issue coverage has been met; and subsidies would be necessary for low-income individuals to purchase insurance. THE PUBLIC PLAN OPTION: The public plan option is shaping up to be one of the most contentious issues in the health reform debate. Proponents also believe of a public plan is necessary to drive private insurers toward true competition. Opponents view it as a step toward government-run health

    Background In many laboratories, researchers store experimental data on their own workstation using spreadsheets. However, this approach poses a number of problems, ranging from sharing issues to inefficient data-mining. Standard spreadsheets are also error-prone, as data do not undergo any validation process. To overcome spreadsheets inherent limitations, a number of proprietary systems have been developed, which laboratories need to pay expensive license fees for. Those costs are usually prohibitive for most laboratories and prevent scientists from benefiting from more sophisticated data management systems. Results In this paper, we propose the EnzymeTracker, a web-based laboratory information management system for sample tracking, as an open-source and flexible alternative that aims at facilitating entry, mining and sharing of experimental biological data. The EnzymeTracker features online spreadsheets and tools for monitoring numerous experiments conducted by several collaborators to identify and characterize samples. It also provides libraries of shared data such as protocols, and administration tools for data access control using OpenID and user/team management. Our system relies on a database management system for efficient data indexing and management and a user-friendly AJAX interface that can be accessed over the Internet. The EnzymeTracker facilitates data entry by dynamically suggesting entries and providing smart data-mining tools to effectively retrieve data. Our system features a number of tools to visualize and annotate experimental data, and export highly customizable reports. It also supports QR matrix barcoding to facilitate sample tracking. Conclusions The EnzymeTracker was designed to be easy to use and offers many benefits over spreadsheets, thus presenting the characteristics required to facilitate acceptance by the scientific community. It has been successfully used for 20 months on a daily basis by over 50 scientists. The EnzymeTracker is

    Full Text Available Abstract Background An innovative approach to learning public health by using feature-length commercial movies was piloted in the fourth year of a medical degree. We aimed to explore how students responded to this approach and the relative effectiveness of two promotional strategies. Firstly we placed DVDs of 15 movies (with public health-related content in the medical school library. Then alternating groups of students (total n = 82 students were exposed to either a brief promotional intervention or a more intensive intervention involving a class presentation. The response rates were 99% at baseline and 85% at follow-up. Findings The level and strength of support for using movies in public health training increased after exposure to the public health module with significantly more students "strongly agreeing". Student behaviour, in terms of movies viewed or accessed from the library, also suggested student interest. While there were no statistically significant differences in median viewing or library access rates between the two intervention groups, the distribution of viewing patterns was shifted favourably. Those exposed to the more intensive intervention (class presentation were significantly more likely to have reported watching at least one movie (97% vs. 81%; p = 0.033 or to having accessed at least one movie from the library (100% vs. 70%, p = 0.0001. Conclusions This pilot study found that the students had very positive attitudes towards viewing public health-related commercial movies. Movie access rates from the library were also favourable.

    物权公示的对象是物权的归属状况,而不是物权的变动。这是由物权特性的客观要求所决定的,物权公示是对物权归属状况的展示,且该展示是一种常态的表征。物权公示的价值是保护物权(所有权)静的安全,保护动的安全是其中的组成部分,保护静的安全才是其最主要或最终的目的。在我国立法模式下,物权的公示是确定物权归属的条件,并由此“定分止争”。物权公示的基本效力,表现为确认物权的归属状况,其他效力都是由此派生的。赋予公示以公信力,是对公示效力的强化。%The object of real right publicity is not the change of real right but the ownership status of the property, which is a normal characterization and is determined by the objective requirements of the characteristics of real right. The value of real right publicity is to protect the safety of quiet status of the real right (ownership), which is the most important or the ultimate goal for real right publicity, and protecting the safety of changeable status is only minor value of real right publicity. Under Chinese legislation mode, the real right publicity can determine the conditions for the ownership of the property, and thus “settle the disputes”. The basic effect of the real right publicity is to confirm the ownership of the property, and other effects are derived from this.It is kind of strengthening to effectiveness of real right publicity by reinvesting real right publicity with credibility.

    The trigger system of the ATLAS experiment is designed to reduce the event rate from the LHC nominal bunch crossing at 40 MHz to about 1 kHz, at the design luminosity of 10^{34} cm^{-2} s{-1}. After a successful period of data taking from 2010 to early 2013, the LHC is restarting in 2015 with much higher instantaneous luminosity and this will increase the load on High Level Trigger system, the second stage of the selection based on software algorithms. More sophisticated algorithms will be needed to achieve higher background rejection while maintaining good efficiency for interesting physics signals. The Fast TracKer is part of the ATLAS trigger upgrade project; it is a hardware processor that will provide, at every level-1 accept (100 kHz) and within 100 microseconds, full tracking information for tracks with momentum as low as 1 GeV. Providing fast extensive access to tracking information, with resolution comparable to the offline reconstruction, the Fast Tracker will for example help the High Level Trigger...
