    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 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 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 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, ...

    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 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...

    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 At the beginning of May, the Pixel detector was successfully extracted from inside CMS. The operation lasted one and a half days each for the forward and barrel Pixel detectors. Everything went smoothly: new people were trained during the exercise and care was taken to minimise radiation exposure – see Image 3.  Lessons learned were noted in an updated written extraction procedure.  Care was also taken to prepare for reinsertion around the new beam pipe next year, with new alignment targets placed on the barrel Pixel detector. All pieces were lifted to the surface and are now safely stored at low temperatures in the dedicated Pixel laboratory at Point 5 (see Image 4 and previous Bulletin).

      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. There are two operating temperatures for the room: 21°C will be used when the Pixel detector components are under cold storage at subzero temperatures in well-sealed “cold boxes,” ...

    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...

In this paper, we aim to make a twofold contribution towards the development of the concept of publics in web science. First, we propose that although the notion of publics raises a variety of issues, two major concerns continue to be user privacy and democratic citizenship on the web. Well-known arguments hold......, this paper points towards an alternative way to think about publics by proposing a pragmatist reorientation of the public/private distinction in web science, away from seeing two spheres that needs to be kept separate, towards seeing the public and the private as something that is continuously connected...

    It is natural in a democratic society that people request more participation in the decision making process. The once centralized government was however reluctant to open more room in this regard concerning the nuclear power industry and radioactive waste management. The environmental impact assessment provided the statuary ground, although limited, for public participation in the environmental issues. A comprehensive social communication program which consists of public information, public education, public relation, and public participation must be established to ensure the smooth realization of a development project. This paper described the relevant situations in Taiwan and recommended various practices to alleviate the NIMBY syndrome. These descriptions and recommendations would be useful particularly for the third world countries facing emerging environmental issues in the near future

    In this article, we outline the link between migration, public health and ethics. Discussing relevant arguments about migration from the perspective of public health and public health ethics. Critical review of theories and frameworks, case-based analysis and systematic identification and discussion of challenges. Migration is a core issue of public health ethics and must take a case-based approach: seeking to identify the specific ethical dimensions and vulnerabilities in each particular context. Public health as a practice, built upon the core value of justice, requires the protection and promotion of migrants' well-being (even if this produces tension with immigration services). Ethical analysis should take all phases of migration into account: before, during and after transit. We argue that migration policies, at least as they relate to migrants' well-being, should be founded upon a shared humanity, respect for human rights and on the idea that effective public health cannot and should not be confined within the borders and to the citizens of any host country. We make the case for migration to be seen as a core issue of public health ethics. Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

    1999-01-01

    The paper presents an overview of current public policy issues relating to biological standardisation and control, drawing on the extensive background material assembled for two recent international reviews, and previously published work. It identifies a number of factors which are destabilising the current system and promoting a climate for change. These include the squeeze on public sector resources, the growth in volume and complexity of biologicals, developing world needs, concerns about harmonisation and new social and ethical issues. It is argued that this situation presents important opportunities for reviewing the existing boundaries between regulatory scientists, industry, and the public, for international agreement on priorities and for harmonisation and mutual recognition. While considerable progress has already been made on these issues at national, regional and global level, there is a need for fuller international participation and the additional impetus that would come from a higher-profile commitment by governments. Such commitment will also be important for the vital questions of sustaining the scientific base and securing the resource for an effective, truly worldwide programme of standardisation and control. An international approach will also be essential in steering biologicals control through the difficult social and ethical questions of the future. WHO, in collaboration with national authorities, has a key role to play in these developments.

    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.

    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

    The Governor of Nevada was notified in 1983 that the Yucca Mountain site is a potentially acceptable site for a nuclear waste storage site. A series of public hearings held produced nearly 400 comments on issues concerning the site nomination. Areas of primary public concern are the impact of the proposed nuclear site on tourism, transportation, and socioeconomic impact on adjacent communities. Results of recent studies showed no impact of high-level waste transport on tourism in the Las Vegas area and on analysis of data accumulated over the 25 to 30 years that high-level radioactive wastes have been transported on Nevada highways showed that no one has been evacuated from their home as the result of an accident involving radioactive waste. A comparison of the possible effects of construction of a nuclear waste storage facility at the Yucca mountain site with the effects of Nevada Test Site indicate that the impact on communities will be minimal

    During 1987 and 1988 in Australia there have been two national meetings on the greenhouse effect and a campaign designed to increase public awareness. A study of the backgrounds, level of comprehension and attitudes of attendees at two state Greenhouse-88 meetings has been undertaken by means of a questionnaire survey and a set of personal interviews. Two crucial caveats pertain: some of the questions reflect the prejudices of the author who is an atmospheric scientist, and the respondents comprise a small, self-selected group. All the ensuing results should be viewed in the context of these caveats. Over 97% of the respondents believe that action should be taken now to alleviate the effects of increased greenhouse gases. Despite the fact that the majority of the 321 respondents are professional people (73%) and that over 53% have tertiary level educational qualifications, there was a failure to grasp some fundamental issues. On the other hand, the respondents generally demanded a relatively low level of confidence (50-70%) about the greenhouse issue from scientists before action is taken. Sixty-four percent believe that life will be worse for them and/or their children in Australia in 'Greenhouse 2025' with the youngest age range being the second most pessimistic group about the future. Relatively little interest was shown in the possibility of obtaining more information on topics that interest climatic scientists but more information was desired on the social and economic implication and on the scientific background to the issues. Overall, teachers are perceived as trying to increase understanding; whereas politicians, multinational corporations, the media and some extreme environmentalists are perceived as often attempting to deceive intentionally. Scientists are seen as neither especially malevolent nor benign. 15 figs., 39 refs.

    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 ...

  20. Public information. Key issue paper no. 5

    2000-01-01

    Nuclear power was welcomed from the outset because it promised highly economic and convenient energy, especially electricity. Even today, nuclear projects espoused by developing nations can stimulate enthusiasm and national pride. However, public unease concerning nuclear power safety was magnified by the accidents at Three Mile Island in 1979 and Chernobyl in 1986. The perceived problem of transport and long term storage of nuclear waste has added to public concerns, as has the risk of the possible proliferation of nuclear weapons. Public information strategies must recognize and seek to address these fears by pointing to the many cumulative years of trouble-free nuclear operations and by stressing the strict rules and oversight designed to protect workers and the public from accidents and radioactive releases. It is against this background that the following material has been compiled. It comes from a variety of sources and reflects the experience mainly of industrialized countries that have national nuclear programs. It is important to underline that it is descriptive rather than prescriptive in nature for two reasons: first, the IAEA is essentially a forum for pooling collective knowledge in this as in other fields; and secondly, the IAEA would not presume to offer a universal formula, since national circumstances vary according to specific political, demographic, social and other factors. Hence only certain parts of this paper may be of direct relevance to any given national situation. (author)

    2009-11-01

    Child labour is a global practice and has many negative outcomes. According to International Labour Organization, child labour is the important source of child exploitation and child abuse in the world today. The Human Rights Commission of Pakistan has estimated the number of Pakistani working children to be around 11-12 millions, out of which, at least, half the children are under the age of ten years. It portrays the society's attitude towards child care. It is therefore, essential to break this vicious cycle and hence, enable the society to produce healthy citizens. This article analyzes the determinants of child labour in the Pakistani context and its implications for child's life, in specific, and for the nation, in general, utilizing the model developed by Clemen-stone & McGuire (1991). Since this practice has complex web of causation, a multidisciplinary approach is required to combat this issue through proposed recommendations.

  8. Science Communication for the Public Understanding of Nuclear Issues

    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.

  15. Gender issues in medical and public health education.

    Science.gov (United States)

    Wong, Y L

    2000-01-01

    There is no doubt that gender bias has been inherent in medical and public health education, research, and clinical practice. This paper discusses the central question for medical and public health educators viz. whether women's health concerns and needs could be best addressed by the conventional biomedical approach to medical and public health education, research, and practice. Gender inequalities in health and gender bias in medical and public health education are revealed. It is found that in most public health and prevention issues related to women's health, the core issue is male-female power relations, and not merely the lack of public health services, medical technology, or information. There is, thus, an urgent need to gender-sensitize public health and medical education. The paper proposes a gender analysis of health to distinguish between biological causes and social explanations for the health differentials between men and women. It also assessed some of the gender approaches to public health and medical education currently adopted in the Asia-Pacific region. It poses the pressing question of how medical and public health educators integrate the gender perspective into medical and public health education. The paper exhorts all medical and public health practitioners to explore new directions and identify innovative strategies to formulate a gender-sensitive curriculum towards the best practices in medicine and public health that will meet the health needs of women and men in the 21st century.

    Public health surveillance is not ethically neutral and yet, ethics guidance and training for surveillance programmes is sparse. Development of ethics guidance should be based on comprehensive and transparently derived overviews of ethical issues and arguments. However, existing overviews on surveillance ethics are limited in scope and in how transparently they derived their results. Our objective was accordingly to provide an overview of ethical issues in public health surveillance; in addition, to list the arguments put forward with regards to arguably the most contested issue in surveillance, that is whether to obtain informed consent. Ethical issues were defined based on principlism. We assumed an ethical issue to arise in surveillance when a relevant normative principle is not adequately considered or two principles come into conflict. We searched Pubmed and Google Books for relevant publications. We analysed and synthesized the data using qualitative content analysis. Our search strategy retrieved 525 references of which 83 were included in the analysis. We identified 86 distinct ethical issues arising in the different phases of the surveillance life-cycle. We further identified 20 distinct conditions that make it more or less justifiable to forego informed consent procedures. This is the first systematic qualitative review of ethical issues in public health surveillance resulting in a comprehensive ethics matrix that can inform guidelines, reports, strategy papers, and educational material and raise awareness among practitioners.

    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

  1. Communicating with the public on nuclear materials disposition issues

    International Nuclear Information System (INIS)

    Stevenson, G.B.; Wherley, P.

    1995-01-01

    The storage and disposition of weapons grade fissile materials involves complex technical issues. The goal of reaching consensus on the best method or methods for storing and ultimately disposing of these materials can only be achieved after an open public discussion of all reasonable alternatives. The US Department of Energy considered a number of factors in developing a program for public involvement. These factors included defining the affected public, public knowledge about the proposed action, decision to be made, availability of pertinent information, current public perceptions, and responding to public input. Based upon an analysis of these factors, three primary techniques were selected for communicating with the public. The techniques are distribution of a quarterly newsletter, establishment of an electronic bulletin board, and holding periodic conference calls and public meetings. The newsletter is designed to reach the widest segment of the public and to be meaningful regardless of the reader's level of familiarity with the project. Periodic conference calls and meeting are used to reach the members of the public who have a real but periodic interest in the issues. The electronic bulletin board is used to communicate with a core group of stakeholders who have a continuing high interest in the total storage and disposition program. Initial indications are that these techniques are effective in reaching a wide segment of the public on highly technical and complex questions related to weapons grade nuclear materials. The effectiveness is not the result of these being new techniques but rather using each technique, to the maximum extent possible, to provide open, on-going, two way communications

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

    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.

  4. Contribution of safety issues to public perceptions of energy systems

    Otway, H.J.; Thomas, K.

    1978-01-01

    Public opposition is an important consideration for those responsible for energy planning; however, the formulation of socially viable policies requires an understanding of the reasons for this opposition. An attitude model was applied to identify the underlying determinants of public perceptions of five energy systems: nuclear, coal, oil, solar and hydro. Empirical results (heterogeneous sample of the general public, N = 224) are reported in which these energy systems were found to be perceived in terms of four basic dimensions: psychological aspects; economic benefits; socio-political implications; environmental and physical safety issues. For the total sample, safety issues made an appreciable contribution to attitudes toward all of the systems except nuclear energy, where it was not significant. A differential analysis of two sub-samples, those respondents PRO and CON nuclear energy, showed that benefits and safety issues were important determinants of PRO attitudes while CON attitudes were primarily due to psychological aspects and concerns about personal and political power. The role of technical information in the formation of public attitudes toward technological policies is discussed

    Recycling radioactively contaminated materials requires varying degrees of interaction among Federal regulatory agencies such as the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA), State governments and regulators, the public, and the Department of Energy. The actions of any of these parties can elicit reactions from the other parties and will raise issues that must be addressed in order to achieve a coherent policy on recycling. The paper discusses potential actions and reactions of Federal regulatory agencies (defined as NRC and EPA), the States, and the Department and the policy issues they raise

    The court-ordered shipping of 750 spent nuclear fuel assemblies from West Valley, New York back to their utility owners has generated considerable public and media interest. This paper discusses the specific concerns of the general public over the West Valley shipments, the issues raised by opposition groups, the interest of public officials and emergency preparedness teams as well as the media coverage generated. An analysis is performed on the effectiveness of the West Valley and utility public information programs utilized in addressing these issues, concerns and interests. Emphasis is placed on communications which work to facilitate the shipments and generate fuel transport acceptance. Information programs are discussed which increase preparedness for nuclear shipments by emergency response teams and build public confidence in their safety. The paper also examines communications which could have further enhanced the shipping campaign to date. Finally, plans are discussed for media preparation with interview training and press conferences. Emphasis is placed on materials provided for the media which have served to generate more favorable print and air time

    2005-01-01

    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.

  10. PageRank tracker: from ranking to tracking.

    Video object tracking is widely used in many real-world applications, and it has been extensively studied for over two decades. However, tracking robustness is still an issue in most existing methods, due to the difficulties with adaptation to environmental or target changes. In order to improve adaptability, this paper formulates the tracking process as a ranking problem, and the PageRank algorithm, which is a well-known webpage ranking algorithm used by Google, is applied. Labeled and unlabeled samples in tracking application are analogous to query webpages and the webpages to be ranked, respectively. Therefore, determining the target is equivalent to finding the unlabeled sample that is the most associated with existing labeled set. We modify the conventional PageRank algorithm in three aspects for tracking application, including graph construction, PageRank vector acquisition and target filtering. Our simulations with the use of various challenging public-domain video sequences reveal that the proposed PageRank tracker outperforms mean-shift tracker, co-tracker, semiboosting and beyond semiboosting trackers in terms of accuracy, robustness and stability.

  11. Interfaith Program for Public Awareness of Nuclear Issues

    International Nuclear Information System (INIS)

    1985-11-01

    Planning for the Interfaith Progam for Public Awareness of Nuclear Issues (IPPANI) began at the time of the Falkland Islands crisis. At that time representatives of certain of the faith groups in Toronto became concerned about the moral and ethical implications of Canada's export of fuel for a CANDU nuclear generating plant in Argentina. In order to accomplish its goals, the Planning Committee devised a program to provide unbiased input to the faith groups' deliberations on the ethical and moral issues involved in the nuclear debate. The development of a fair set of questions was aided by obtaining advice from the Canadian Nuclear Association (CNA), and from Energy Probe and others. The work of preparing a suitable agenda was completed early in 1984. Its result was embodied in appendices to the public document promoting the program, which is appended to this report. Invitations were sent to over six hundred individuals and organizations to appear before the panelists as 'presenters'. The resulting invitation list included spokespeople for both 'pro' and 'anti' nuclear positions on each of the three topics, as well as some who were found to be 'in the middle'. The three major topics were domestic nuclear issues, international trade and military uses of nuclear materials and technology. The next task of the Planning Committee is that of embodying the process and its results in an educational program for the supplementary and parochial school systems. The production of this book is the first step in that task

  12. Working in the Public Sector. Introduction to the Thematic Issue

    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 (...

    With the increased public perception of the future scale of dependence on nuclear energy a debate has started, raising the level of public awareness of the social, political and technical risks that are inevitably associated with the large-scale and accelerating adoption of nuclear power generation. The nuclear industry has given a mixed response to this debate, to accusations of irresponsibility and to demands for more specific attention to the recognized hazards of the fuel cycle. In this situation, non-governmental bodies such as the World Council of Churches, has taken the responsibility to examine the issues so far identified and to place these in a social and ethical context.

    Sleep specialists have proposed measures to counteract the negative short- and long-term consequences of sleep debt, and some have suggested the nap as a potential and powerful "public health tool". Here, we address this countermeasure aspect of napping viewed as an action against sleep deprivation rather than an action associated with poor health. We review the physiological functions that have been associated positively with napping in both public health and clinical settings (sleep-related accidents, work and school, and cardiovascular risk) and in laboratory-based studies with potential public health issues (cognitive performance, stress, immune function and pain sensitivity). We also discuss the circumstances in which napping-depending on several factors, including nap duration, frequency, and age-could be a potential public health tool and a countermeasure for sleep loss in terms of reducing accidents and cardiovascular events and improving sleep-restriction-sensitive working performance. However, the impact of napping and the nature of the sleep stage(s) involved still need to be evaluated, especially from the perspective of coping strategies in populations with chronic sleep debt, such as night and shift workers.

    Full Text Available Abstract Congenital anomalies are already the second cause of infant mortality in Brazil, as in many other middle-income countries in Latin America. Birth defects are a result of both genetic and environmental factors, but a multifactorial etiology has been more frequently observed. Here, we address the environmental causes of birth defects – or teratogens – as a public health issue and present their mechanisms of action, categories and their respective maternal-fetal deleterious effects. We also present a survey from 2008 to 2013 of Brazilian cases involving congenital anomalies (annual average of 20,205, fetal deaths (annual average of 1,530, infant hospitalizations (annual average of 82,452, number of deaths of hospitalized infants (annual average of 2,175, and the average cost of hospitalizations (annual cost of $7,758. Moreover, we report on Brazilian cases of teratogenesis due to the recent Zika virus infection, and to the use of misoprostol, thalidomide, alcohol and illicit drugs. Special attention has been given to the Zika virus infection, now proven to be responsible for the microcephaly outbreak in Brazil, with 8,039 cases under investigation (from October 2015 to June 2016. From those cases, 1,616 were confirmed and 324 deaths occurred due to microcephaly complications or alterations on the central nervous system. Congenital anomalies impact life quality and raise costs in specialized care, justifying the classification of teratogens as a public health issue.

    The Electronic Systems Engineering Department of the Computing Division at the Fermi National Accelerator Laboratory is carrying out R and D investigations for the upgrade of the power distribution system of the Compact Muon Solenoid (CMS) Pixel Tracker at the Large Hadron Collider (LHC). Among the goals of this effort is that of analyzing the feasibility of alternative powering schemes for the forward tracker, including DC to DC voltage conversion techniques using commercially available and custom switching regulator circuits. Tests of these approaches are performed using the PSI46 pixel readout chip currently in use at the CMS Tracker. Performance measures of the detector electronics will include pixel noise and threshold dispersion results. Issues related to susceptibility to switching noise will be studied and presented. In this paper, we describe the current power distribution network of the CMS Tracker, study the implications of the proposed upgrade with DC-DC converters powering scheme and perform noise susceptibility analysis.

    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.

    ENRESA (Empresa Nacional de Residuos Radiactivos, S.A.), is a State-owned company, founded in 1985 and is responsible for radioactive waste management in Spain. ENRESA's activities are carried out in accordance with a General Radioactive Waste Plant approved by the Spanish Government. In Spain, as in most countries, the public is concerned about many of the activities involving radioactive or rad-waste management; this concern arises for different reasons, but mainly due to lack of information on the matter. This situation leads to the information available being misused by certain politicians, green groups and media, which serves to increase the distrust with which the public sometimes views responsible companies and institutions. At the root of both these problems is a lack of political consensus regarding development of the activity. To gain public acceptance, it would be necessary to develop a long-term information policy, since in the field of communications results are only ever achieved in the long term. ENRESA is carrying out an on-going Communication Plan (CP), implemented successfully in the areas surrounding a low- and intermediate-level waste disposal site and a disused uranium mill in which remedial actions are currently being performed. Implementation of this plan at national level is being accomplished stepwise. This document deals with the most relevant issues relating to the radioactive waste situation in Spain and with the efforts made in communications

    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.

  7. Furthering better communication and understanding of nuclear issues through public education: a public school teacher's perspective

    1984-01-01

    Recent reports of national commissions and study groups have pointed out that the American educational system is not meeting the needs of its students. Uniformly, the reports call for a new instructional focus designed to achieve the goal of ''universal scientific and technological literacy for citizenship.'' The population's inability to deal with numerous controversial science-related social issues forms the basis for this call for educational reform. Foremost on the list of science-related social issues are nuclear issues in general and the storage of nuclear waste in particular. The National Council for the Social Studies (NCSS) 1983 publication ''Guidelines for Teaching Science Related Social Issues'' was designed to encourage stronger instructional emphasis on science-related social issues, and to provide social studies teachers with a rational and structure for the presentation of the issues. This paper discusses the dilemmas faced by educators who attempt to deal with science-related social issues. Also, it addresses the need for instructional materials in order to effectively address nuclear issues in the classroom

    Hong, Esther S; Zeeb, Hajo; Repacholi, Michael H

    2006-01-01

    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.

    An intelligent tracker capable of robotic applications requiring guidance and control of platforms, robotic arms, and end effectors has been developed. This packaged system capable of supervised autonomous robotic functions is partitioned into a multiple processor/parallel processing configuration. The system currently interfaces to cameras but has the capability to also use three-dimensional inputs from scanning laser rangers. The inputs are fed into an image processing and tracking section where the camera inputs are conditioned for the multiple tracker algorithms. An executive section monitors the image processing and tracker outputs and performs all the control and decision processes. The present architecture of the system is presented with discussion of its evolutionary growth for space applications. An autonomous rendezvous demonstration of this system was performed last year. More realistic demonstrations in planning are discussed.

    Through a careful process of investigation and inquiry, the World Council of Churches (WCC) has become aware of a decline of public confidence in existing social institutions responsible for maintaining and securing the nuclear fuel cycle. In addressing this concern, the World Council of Churches seeks a direct assurance from the IAEA and other responsible government bodies that new initiatives will be taken to resolve this anxiety and to place the acknowledged risks of an expanding nuclear power industry in a more realistic long-term perspective. The provision of energy resources for all peoples is an essential part of the struggle for a more just, participatory and sustainable society. In the light of current uncertainties over the maintenance of energy supplies, particularly to large urban communities, the WCC appreciates the necessity of retaining nuclear power as a viable option for the future in many countries. However, the credibility of the option can be achieved only through the resolution of the major questions that are inherent in the use of nuclear technology. The paper discusses the following questions, which must be tackled without further delay and certainly before a large and irreversible world-wide commitment is made: (1) The need for an open public debate. Without full public consultation on the social and ethical implications of long-term energy choices, decisions will be taken largely in terms of commercial and consequently short-term economic interest. (2) Facing the long-term risks of adopting nuclear technology. (3) Access versus security. Concern for the security of sensitive nuclear technologies has produced the secretive nuclear club. A just global society implies not merely equal opportunity to aspire and to achieve, but affirmative action to redress imbalances. (4) Military implications. (5) Social implications of nuclear energy. (6) Ethical and religious issues. (author)

    ENRESA (Empresa Nacional de Residuos Radiactivos, S.A.), is a State-owned company, founded in 1984 and is responsible for radioactive waste management in Spain. ENRESA's activities are carried out in accordance with a General Radioactive Waste Plan approved by the Spanish Government. In Spain, as in most countries, the public is concerned about many of the activities involving radioactivity or rad waste management; this concern arises for different reasons, being one of them the lack of information on the matter. This situation often leads to an information misuse by certain politicians, green groups and media, which can increase the distrust of the public to responsible companies and institutions. At the root of both these problems there is also a lack of political consensus regarding projects and related activities. To gain public acceptance, it is necessary to develop a long-term information policy since, in the field of communication, results can only be achieved in the long term. ENRESA is carrying out an on-going Communication Plan (CP), implemented successfully in the areas surrounding a low and intermediate level waste disposal site and a 500 MW nuclear power station (Vandellos 1) which is currently being dismantled. Implementation of this plan at national level is being accomplished stepwise. This document deals with the most relevant issues relating to the radioactive waste situation in Spain and with the efforts made in communications. From the very beginning the situation regarding public opinion was one of clear opposition. At regional level, and particularly in the area surrounding the El Cabril site, both the general public and the opinion leaders were opposed to any action by ENRESA. This opposition included some anti-ENRESA demonstrations right in front of the main entrance to El Cabril. At national level politicians, journalists, etc., did not show much confidence in ENRESA's activities, and the information published in the newspapers was always

    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

    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 accommodate

    The World Council of Churches is aware of a decline of public confidence in existing social institutions responsible for maintaining and securing the nuclear fuel cycle. In addressing this concern, the World Council of Churches seeks a direct assurance from the IAEA and other responsible governmental bodies that new initiatives will be taken to resolve this anxiety and to place the acknowledged risks of an expanding nuclear power industry in a more realistic long-term perspective. The provision of energy resources for all peoples is an essential part of the struggle for a more just, participatory and sustainable society. The W.C.C. appreciates the necessity of retaining nuclear power as a viable option for the future in many countries. However, the credibility of the option can be achieved only through the resolution of the major questions that are inherent in the use of nuclear technology. These questions must be tackled before a large and irreversible world-wide commitment is made. At present, the public debate is confused. Advocates of nuclear energy plead the achievements of unproven technology, minimizing the unsolved problems, while critics ignore the societal costs of other major energy options, and demand an unrealistic absolute perfection in the design and construction of nuclear power systems. The churches seek to encourage an informed public examination of these issues. The W.C.C. stresses the necessity of resolving the problems of secure waste disposal and those posed by the drift into a dependency on the plutonium fuel economy. A just global society implies not merely equal opportunity to aspire and to achieve, but affirmative action to redress imbalances. This is incompatible with the pseudo-secrecy and patronage practiced by developed nuclear countries. The W.C.C. is concerned how the ''access'' versus ''security'' issue is to be resolved. The development of nuclear energy for civilian purposes is linked with the development of nuclear weapons. The

    2016-01-01

    The detector for the LHCb upgrade is designed for 40MHz readout, allowing the experiment to run at an instantaneous luminosity of 2x10^33 cm$^2$s$^-1$. The upgrade of the tracker subsystem in front of the dipole magnet, the Upstream Tracker, is crucial for charged track reconstruction and fast trigger decisions based on a tracking algorithm involving also vertex detector information. The detector consists of 4 planes with a total area of about 8.5m$^2$, made of single sided silicon strip sensors read-out by a novel custom-made ASIC (SALT). Details on the performance of prototype sensors, front-end electronics, near-detector electronics and mechanical components are presented.

    To provide improvements in the performance of existing tracker data visualization tools in IGUANA, a 2D visualisation software has been developed, using the object oriented paradigm and software engineering techniques. We have designed 2D graphics objects and some of them have been implemented. The access to the new objects is made in ORCA plugin of IGUANA CMS. A new tracker object oriented model has been designed for developing these 2D graphics objects. The model consists of new classes which represent all its components (layers, modules, rings, petals, rods).The new classes are described here. The last part of this document contains a user manual of the software and will be updated with new releases.

    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

  8. Public policy and adolescent pregnancy: a reexamination of the issues.

    In the United States 45% of female adolescents engage in premarital sex; 40% will become pregnant before reaching the age of 20; and 4/5 of these pregnancies will be unintended. Adolescent pregnancy has been associated with increased health risks for both the mother and the child. Only 6 in 10 adolescents will graduate from high school compared with 9 in 10 of their peers who delayed parenthood. The increasing number of single-parent families has contributed significantly to the increase in child poverty rates from 15% in 1960 to 20.3% in 1988. Further, such families cost billions of dollars to taxpayers because of public assistance and medical care. From a historical viewpoint the number of teen childbearing reached a peak in 1957 with 97.3 births per 1000 women 15-17 years old; it declined to 52.8/1000 by 1977 and to 51.8/1000 by the 1980s. The legalization of abortion in 1973 had a major impact on the resolution of adolescent pregnancies. Since the 1960s there has been a faster increase in early sexual activity, pregnancy, and birth among White adolescents than among minority groups. The United States has higher rates than western European countries, while it is also more ambivalent on sexuality issues. Tremendous change did take place in the 1960s in American culture as regards the family, and social and sexual relationships. Yet there is still a double standard with respect to female morality, and adolescents get a conflicting message about sexuality. Teenage mothers and their infants face an uncertain economic future because the much maligned welfare system is undergoing an overhaul and the market is shrinking for unskilled workers. Although increasing numbers of pregnant adolescents remained in school after amendments were passed to the education act, adolescent pregnancy has not been tackled at its very footing, its socioeconomic causes.

    The new silicon tracker layout (V4) is presented. The system aspects of the construction are discussed together with the expected tracking performance. Because of the high radiation environment in which the detectors will operate, particular care has been devoted to the study of the characteristics of heavily irradiated detectors. This includes studies on performance (charge collection, cluster size, resolution, efficiency) as a function of the bias voltage, integrated fluence, incidence angle and temperature. (author)

    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

    We argue for greater recognition of the risky nature of most policy decisions. In this context we discuss the gulf between public risk perceptions and attitudes and those of 'experts'. Public views of risk are often inconsistent and seemingly irrational. They nevertheless influence policy choices in a democracy. On the other hand, experts often claim unjustifiable levels of confidence in their predictions of policy choice outcomes, creating a lack of public faith in their recommendations. Whi...

    1996-01-01

    A brief history of public acceptance of nuclear energy in Slovenia is given. While in former Yugoslavia a problem of public acceptance virtually did not exist because of undemocratic social system, it grew larger and larger with the process of democratization in late eighties. The first democratic government in Slovenia had to abandon its original idea for an early closure of the nuclear power plant Krsko. In 1995 and 1996 there were two attempts to organize the national referendum about the future of the plant. The lessons learned from the public debates in recent years could help other countries entering the nuclear program to prepare and implement efficient public information strategy. (author)

    Full Text Available Hepatitis B infection is endemic in many parts of the world, including Korea. Basic knowledge of the hepatitis B virus by the public is a prerequisite for the development of a successful vaccination program. A survey was conducted in rural Korea to examine public knowledge of hepatitis B etiology, symptoms, transmission, risk factors and prevention. It was found that knowledge independently correlated with education and female sex, but that overall knowledge of hepatitis B was poor. The preferred information sources in order of preference were physicians, television and public health nurses. This information may be useful in designing public health education and vaccination programs in developing populations.

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. Practical value the conclusions and suggestions formulated in the study will contribute to the active implementation of public control in the municipalities will enhance the ability of citizens and civil society institutions to monitor the authorities and will have a positive impact on transparency of local selfgovernment.

  2. Issues related to public perception of radioactive waste management options

    International Nuclear Information System (INIS)

    Taylor, D.M.

    2007-01-01

    Public perceptions about radioactive waste are generally rather or even strongly negative. They are also very poorly informed. This is rather unfortunate as it is these perceptions that appear to greatly influence the Public views on nuclear energy in general. This, in turn, has had an influence on political decisions. On the other hand, in a very clear majority of the Member States of the European Union, the Public have already indicated that they would be ready to accept the important role of nuclear in their future energy mix as long as all the radioactive wastes can be safely managed. However perceptions about nuclear energy and radioactive waste should be seen in the context of the Public wider perceptions on energy and, in particular, the role in the future of different sources. It may be wrong for political decisions on nuclear energy in the future to rely to heavily on the Public perceptions. (author)

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.

    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.

    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.

  9. The ATLAS Fast Tracker

    CERN Document Server

    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. Patte...

    Haefner, Petra; The ATLAS collaboration

    2010-01-01

    The SemiConductor Tracker (SCT), made up from silicon micro-strip detectors is the key precision tracking device in ATLAS, one of the experiments at CERN LHC. The completed SCT is in very good shape: 99.3% of the SCT strips are operational, 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 and observed problems, with stress on the sensor and electronics performance. TWEPP Summary 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 SemiConductor Tracker (SCT) is the key precision tracking device in ATLAS, made up from silicon micro-strip detectors processed in the planar p-in-n technology. The signal from the strips is processed in the front-end ASICS ABCD3TA, working in the binary readout mode. Data i...

    1995-01-01

    This report provides a review of impressions obtained from public interactions regarding the risk of volcanism for underground storage of radioactive waste. These impressions were gained through participation in numerous contacts for the Yucca Mountain Site Characterization Project during the last six years. A conclusion emerging from public interactions is that scientists and those responsible for policy decisions must become more familiar with risk assessment, risk communication, and the requirements of objectively examining decision options for defining acceptable risk

    Misnon, Fauzan Amin; Hu, Yeoh Siong; Rahman, Irman Abd.; Yasir, Muhamad Samudi

    2017-01-01

    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.

    Science.gov (United States)

    Leão, Luís Henrique da Costa

    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.

    2006-01-01

    The conclusions and recommendations of this session can be summarized this way. - Basic goal for the regulator is to protect the public and communication is a must to fully achieve this goal. - Regulator should become the prime source of information to the public and the media, regulator should base its actions upon values of competence, independence, transparency and stringency. - Set up of a Information and Communication Policy will help for consistency and efficiency. Policy will include setting goals, strategies, organisational aspects, procedures, and tools. Practices should be developed in accordance with local culture. - Challenges will consider transparency, public involvement and consultation with the stakeholders. - Practices will include in general: - Interactions with the media like press releases, news conferences, media workshops. Printed materials from plant periodical status reports, to periodical and annual reports and specific reports. Audio-visual materials. Use of radio and TV. Web site and electronic mail. - Method chosen depends on the targeted audience and the relevance of the topic. - Messages should be clearly understandable. Do not dehumanize the message by making it technically unintelligible. - Two excellent examples presented. How local culture and social characteristics were taken into account in designing and implementing plans is key for success. - Municipalities are to be considered as front line stakeholders. - Communicators role is relevant to meet regulatory needs. Good collaboration between communicators and technical staff produces benefits for the nuclear regulator and the public. (authors)

  1. Rendezvous and docking tracker

    Ray, Art J.; Ross, Susan E.; Deming, Douglas R.

    1986-01-01

    A conceptual solid-state rendezvous and docking tracker (RDT) has been devised for generating range and attitude data for a docking vehicle relative to a target vehicle. Emphasis is placed on the approach of the Orbiter to a link with the Space Station. Three laser illuminators ring the optical axis of the lens a directed toward retroreflectors on the target vehicle. Each retroreflector is equipped with a bandpass filter for a designated illumination frequency. Data are collected sequentially over a 20 deg field of view as the range closes to 100-1000 m. A fourth ranging retroreflector 0.3 m from center is employed during close-in maneuvers. The system provides tracking data on motions with 6 deg of freedom, and furnishes 500 msec updates (to be enhanced to 100 msec) to the operator at a computer console.

  2. The LHCb Silicon Tracker

    Tobin, Mark, E-mail: Mark.Tobin@epfl.ch

    2016-09-21

    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.

    The public of the XXI Century is avid for information about the newest technical and scientific advances occurred and on how do they impact in our daily life. All over the world, the channels of mass communication provide all kind of valuable knowledge that could be of interest for the audience. Part of this broadcasted information however, is managed without the required scientific strictness due to its technical complexity or in most the cases, because it is being used for sensational purposes. The Nuclear Energy has been subjected to different manipulations and misinterpretation by the media because the disastrous consequences of its initial utilization for war purposes. For this reason, the International Atomic Energy Agency has recommended to its Member States the development of a coherent policy for public information based on an adequate real balance of the risk and the benefits of the pacific uses of the nuclear energy, with special emphasis in the diagnosis and treatment of diseases. In this context, the Regulatory Bodies are invited to use all available resources for information distribution to provide the truth that the society requires with transparency and the appropriate technical strictness as well as to develop periodical assessment on how does the population incorporate this information and what changes on the public perception of the nuclear energy have occurred. In line with the policy of the Government of the Republic of Cuba concerning the systematic improvement and strengthening the level of the general culture of our population, a comprehensive course entitled 'Radiation and Life' was designed and prepared by the authors of the present paper, and broadcasted by the Cuban television in the popular programme 'University for all'. The email recipient 'radiacionesyvida at cnsn.cu' was specially implemented to assess the impact of this course in the public opinion. This email address was used as an effective way of interaction between the lectures

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

    Science.gov (United States)

    Soares, Catharina Leite Matos

    2012-01-01

    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.

  7. Economic issues of the Sizewell B public enquiry

    International Nuclear Information System (INIS)

    Foster, C.

    1987-01-01

    The economic arguments and conclusions reached in the Layfield Report of the Sizewell-B public inquiry are restated. The key test for deciding whether Sizewell-B should be built was the net effective cost per kW per annum (the net cost of supplying electricity from a new power station including capital and operating costs) compared with the net avoidable cost (the cost of withdrawing a plant from the generating system). If the net effective cost is less than the net avoidable cost the construction is economically worthwhile. The effective cost calculations are given. The argument in favour not only had to show that nuclear was economically favourable over coal or any other fuel but that the pressurized water reactor design was preferable to the advanced gas-cooled reactor type. The price of coal, (at the time of the Inquiry and in the future) is tabulated. The changed economic situation between the end of the Inquiry and the publication of the Inquiry Report did not invalidate the decision made. There is only a one in seven chance that a coal-fired station will provide new capacity at lower cost than Sizewell-B. The figures used for CEGB's case to the Public Inquiry are given. (UK)

  8. Public communication activities of JAPC on the issue of radiation

    Hiroshima occasionally but inevitably reminds the Japanese nation of the A-bomb casualties in terms of radiation hazards with mass-destruction. Even peaceful use of nuclear energy is easily perceived as a synonym of menacing nuke'. Firstly, nuclear PA is to get rid of concerns among the general public by credibility to be established by bi-directional communications and common sense as well as technical integrity. JAPC is in direct contacts with the people by such means as guiding tours to nuclear plants, sitting together for exchange of opinions, or having every employee to be a PA person with his or her neighbors. It is our lesson that PA success definitely depends on the authentic person-to-person bond of trust and credibility with right communications. The general public tends to get excessively concerned, once they are put in process of their perception of nuclear information, all of sudden from daily indifference, via mass-media or education in various forms. Such concerns override nuclear benefits and precipitate especially against invisible phenomena, technical complexity, black boxes, probability of risks. For example, radiologists or law-makers do not mind 10 digit numbers of radiation expressed in Becquerel (rather than Curie). Mass media simply report 5-6 digit higher spikes than normal level even if it is well below permissible level. But the general public is overwhelmed by such gigantic spike ratio. Right communications for nuclear PA shall be made on common sense of the society. (author)

    Full Text Available Over the last years, the need for changing the current model of European public health systems has been repeatedly addressed, in order to ensure their sustainability. Following this line, IT has always been referred to as one of the key instruments for enhancing the information management processes of healthcare organizations, thus contributing to the improvement and evolution of health systems. On the IT field, Big Data solutions are expected to play a main role, since they are designed for handling huge amounts of information in a fast and efficient way, allowing users to make important decisions quickly. This article reviews the main features of the European public health system model and the corresponding healthcare and management-related information systems, the challenges that these health systems are currently facing, and the possible contributions of Big Data solutions to this field. To that end, the authors share their professional experience on the Spanish public health system, and review the existing literature related to this topic.

    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.

    1992-01-01

    The state of public involvement in environmental, safety, and health issues at the DOE Nuclear Weapons Complex is assessed through identification of existing opportunities for public involvement and through interviews with representatives of ten local citizen groups active in these issues at weapons facilities in their communities. A framework for analyzing existing means of public involvement is developed. On the whole, opportunities for public involvement are inadequate. Provisions for public involvement are lacking in several key stages of the decision-making process. Consequently, adversarial means of public involvement have generally been more effective than cooperative means in motivating change in the Weapons Complex. Citizen advisory boards, both on the local and national level, may provide a means of improving public involvement in Weapons Complex issues. (author)

    2015-01-01

    The purpose of this descriptive, cross-sectional study was to identify Public Health Nurses' (PHN) perceived motivators and barriers to seeking PHN board certification. In collaboration with the Quad Council of Public Health Nursing Organizations, PHNs from across the United States were invited to complete the PHN Certification Survey, a 14-item online questionnaire. A total of 912 surveys were completed. PHNs were motivated to seek PHN board certification by three overarching categories: professional competence, personal satisfaction, and financial incentives. Frequently cited barriers to certification were lack of knowledge of certification opportunities, being unaware of eligibility criteria, cost, perceived lack of value/reward by employer, and preparation time. Demonstrating a highly educated, competent, and reliable PHN workforce can only be achieved through ongoing professional development and credentialing. PH stakeholders (i.e., PHN organizations, employers, PHNs, etc.) need a strategic approach to address the main barriers to certification identified in this study (a) awareness of certification and eligibility criteria, and (b) recognition of the credential by employers. In addition, research on the relationship between PHN credentialing and population health outcomes is essential. © 2015 Wiley Periodicals, Inc.

    A conceptual framework is proposed within which the notion of risk as normally used in risk assessment (RA) could be enlarged in line with the real substance of social issues of technology policy, to help avoid RA's threatened irrelevance to social decision making. It is argued that the frequent organizational incoherence and thus the unviability of modern technology arises from 'social alienation' between the innovation-commitment phase and the implementation of the technology in society. The roles of technical elites and of particular concepts of technology in this alienation are emphasized. One of the case studies deals with 'Nuclear power - myths of scientific and organizational realism' and discusses the UK nuclear 'programme' and the Three Mile Island accident. (author)

    As a result of the increase in genetic testing and the fear of discrimination by insurance companies, employers, and society as a result of genetic testing, the disciplines of ethics, public health, and genetics have converged. Whether relatives of someone with a positive predictive genetic test should be notified of the results and risks is a matter urgently in need of debate. Such a debate must encompass the moral and ethical obligations of the diagnosing physician and the patient. The decision to inform or not will vary depending on what moral theory is used. Utilising the utilitarian and libertarian theories produces different outcomes. The principles of justice and non‐maleficence will also play an important role in the decision. PMID:16507657

    2018-06-01

    Attention to physician well-being has traditionally focused on substance abuse, usually with disciplinary implications. But, in recent years, greater notice has been granted toward physician burnout and overall wellness. Burnout and its sequelae not only affect physicians and physicians-in-training as individuals, but the impact then multiplies as it affects these physicians' patients, colleagues, and hospital systems. In addition, the American Medical Association Code of Medical Ethics charges physicians with a responsibility to maintain their own health and wellness as well as promote that of their colleagues. Therefore, the question of physician wellness has both public health and ethical implications. The causes of burnout are multifactorial, and the solutions to sustainable change are multitiered.

    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.

  20. Nuclear power as a public issue. Protection of the public interest

    International Nuclear Information System (INIS)

    Doederlein, J.M.

    1977-01-01

    In evaluating the future role of nuclear power, it should be necessary to perform a rational and quantitative comparison of power production alternatives on at least the following four parameters: health effects, environmental effects, economy, and resource availability. The evaluations should cover all steps from fuel production through waste disposal. Less detailed knowledge is available on health effects from air pollution than from radioactivity. However, the present body of knowledge clearly indicates that large-scale use of nuclear power instead of fossil fuels will save thousands of human lives annually. This is probably one of the most compelling arguments for nuclear power. A number of irrational political, ethical and emotional factors may be of decisive importance in a large-scale choice of power plant types. However, an evaluation of rational and quantifiable factors may serve one important function in telling how many lives, which environmental improvements and what economic advantages must be sacrificed in order to satisfy such irrational demands. In any case it should be recognized that the public interest is best served by maximum use of the broad knowledge available on costs and benefits of alternative electric power generation forms. Obviously, energy policy is not an area where all questions can be tackled in an absolutely rational and objective way. However, a number of absolute restrictions are set by the laws of nature, others by present technological abilities. Such restrictions cannot be changed by wishful thinking, political or otherwise. On one hand, this may serve to define the role of the technological community in making both the nuclear and other more important decisions. On the other hand, these are facts which are not fully appreciated by those making a controversial issue of nuclear power. When defining the role of the professional in the nuclear issue the following point should be considered. A scientist or technologist using his

  1. The TRADEX Multitarget Tracker

    Science.gov (United States)

    Meurer, Glenn W., Jr.

    The Multitarget Tracker (MTT) is a real-time signal processing and data processing system installed in the TRADEX radar at the Kiernan Reentry Measurements Site (KREMS) on Kwajalein Atoll in the Marshall Islands. The TRADEX radar is a high-power, high-sensitivity instrumentation radar that was originally designed to track and gather signature data on a single target. The MTT is designed to detect and track as many as 63 targets within the beam of the radar. It provides data necessary for determining the angular locations and ranges of all of these targets, as well as signature data necessary for target identification. The TRADEX MTT is unique because it utilizes a large, mechanically steered, pencil-beam antenna, whereas other MTT systems generally rely on electronically steered antennas or rotating antenna platforms. The MTT system automatically processes received signals, reports targets, initiates and maintains target track files, and presents target information to the radar operators through real-time interactive graphical displays. This information is given to the KREMS Control Center and from there is made available to other systems in the test range. This article presents an overview of the TRADEX MTT system and discusses its implementation, application, and operation.

    We propose the use of Tracker, freeware for video analysis, to analyse the moment of inertia (I) of a cylindrical plate. Three experiments are performed to validate the proposed method. The first experiment is dedicated to find the linear coefficient of rotational friction (b) for our system. By omitting the effect of such friction, we derive I for a cylindrical plate rotated around its central axis from the other two experiments based on the relation between torque and angular acceleration of rotational motion and conservation of energy. Movies of the rotating plate and hung masses are recorded. As a result, we have the deviation of I from its theoretical value of 0.4% and 3.3%, respectively. Our setup is completely constructed from locally available inexpensive materials and the experimental results indicate that the system is highly reliable. This work should pave the way for those who prefer to build a similar setup from scratch at relatively low cost compared to commercial units. (paper)

  3. CMS Tracker Model

    CERN Multimedia

    Model of the tracking detector for the CMS experiment at the LHC. This object is a mock-up of an early design of the CMS Tracker mechanics. It is a segment of a “Wheel” to support Micro-Strip Gas Chamber (MSGC) detector modules on the outer layers and silicon-strip detector modules in the innermost layers. The particularity of that design is that modules are organised in spirals, along which power and optical cables and cooling pipes were planned to be routed. Some of such spirals are illustrated in the mock-up by the colors of the modules. With the detector development it became, however, evident that the silicon detectors would need to be operated in LHC experiments in cold temperatures, while the MSGC could stay in normal room-temperature. That split in two temperatures lead to separating those two detector types by a thermal barrier and therefore jeopardizing the idea of using common, vertical Wheels with services arranged along spirals.

    A market survey on available TDCs for reading out the LHCb Outer Tracker has left over only one TDC, which is not optimal for this purpose. Hence, a new readout architecture which is based on a TDC to be developed anew has been defined. This system fits optimal the requirements of the LHCb Outer Tracker and also should be much cheaper. The system and its main issues are described in this paper.

    The LHCb Silicon Tracker is part of the main tracking system of the LHCb detector at the LHC. It measures very precisely the particle trajectories coming from the interaction point in the region of high occupancies around the beam axis. After presenting our production and comissioning issues in TWEPP 2008, we report on our running experience. Focusing on electronic and hardware issues as well as operation and maintenance adversities, we describe the lessons learned and the pitfalls encountered after three years of successful operation.

    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.

  7. Issues of public policy in the USA raised by amniocentesis.

    Science.gov (United States)

    Etzioni, A

    1976-03-01

    Amniocentesis, a procedure which can detect during pregnancy whether or not the fetus will develop into a mongol or one affected by other serious chromosomal defects, if given to all pregnant women aged 40 and over, would save both human suffering and economic loss to the community. The procedure is not at present widely used for various reasons, not all of them medical, and, if the test result is positive abortion is the remedy. The author describes an important clinical trial being conducted in the USA at the present time but suggests that an educational programme should be undertaken to inform the public of the existence of this procedure and its applications even before the results of the American large-scale trial can be known and evaluated. Amniocentesis and its use, Professor Etzioni concludes, is not the only genetic tool which should be reviewed in a manner which would give an overall picture. He compares those who are concerned with these matters to the citizens of Britain when they saw the first steam engine. They did not perceive the social changes--the industrial revolution--that would follow. In our time a 'genetic revolution' may not be long delayed.

  8. Teen pregnancy: a public health issue or political football?

    Clark, M P

    1996-08-01

    Politicians in the US have made adolescent parents the scapegoat of changing cultural patterns by suggesting punitive solutions to nonmarital births rather than addressing underlying causes of premature child-bearing. It is known that the percentages of young people of all races and all social classes reporting early, nonmarital sexual intercourse have increased dramatically, while adolescent fertility rates peaked in the 1950s. Improved access to contraception and abortion caused a decline in teen pregnancy and birth rates from 1970 to 1986. During 1986-91, service providers could not match growing demand, and the birth rate increased 25%. Increased rates of sexual activity have also led to increases in the incidence of sexually transmitted diseases (STDs) and HIV/AIDS among adolescents. This situation was exacerbated by Reagan and Bush policies, which reduced funding for services to adolescents and supported abstinence-only sex education courses. The concern voiced by policy-makers today centers on nonmarital childbearing by low-income adolescents who will rely on public assistance to survive. A proper response to this situation would involve the following policy actions: 1) mandating comprehensive sexuality education from kindergarten through high school, 2) funding mentoring programs, 3) improving economic and educational opportunities, 4) expanding STD and HIV/AIDS prevention programs, 5) increasing access to confidential health services (including mental health care and substance abuse treatment), 6) expanding child sexual abuse prevention and intervention programs, and 7) increasing access to and acceptability of teen contraceptive usage and abortion.

  9. Why Banning Embedded Sales Commissions Is a Public Policy Issue

    Directory of Open Access Journals (Sweden)

    Henri-Paul Rousseau

    2017-07-01

    Full Text Available Regulatory authorities have consulted on the option of banning embedded sales commissions for Canadian financial advisors. Such an action would create more problems than it would solve. It would have serious ramifications for Canadians’ access to financial advice and raise issues of choice, industry concentration and price transparency for clients seeking advice on investments and retirement. Financial advisors have much greater knowledge of investments than their clients, who rightly expect value from their advisors’ services. Advisors may also face conflicts of interest when they make recommendations about a financial product whose manufacturer might be paying the advisor for selling its products. Banning sales commissions from the manufacturers and having the client pay the advisor directly instead brings its own problems. This is because financial advice is a good with peculiar characteristics. Firstly, financial advice has three fundamental components – the alpha, beta and gamma factors. Together, they define the roles financial advisors play: (alpha asset or portfolio manager, (beta asset allocator (rebalancing a client’s portfolio, and (gamma coach with regard to savings discipline and financial planning. Financial advice has value thanks to the interplay between the three factors. Studies of the issue which have focused on one factor at a time, usually the alpha, produce results that are skewed; however, when studies measure all three factors, the evidence shows that financial advice has significant value, greater than the usual cost charged to clients. Secondly, financial advice is an “experience good”, meaning that clients don’t know ahead of time how good financial advice is until they see how it works out. Assessing the value of financial advice may take many years. Since they can’t immediately measure what they’re paying for, clients with modest incomes or wealth are usually willing only to pay low fees, or not pay

  10. Issues for bringing digital libraries into public use

    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.

  11. Burns From Hot Wheat Bags: A Public Safety Issue

    Science.gov (United States)

    Collins, Anna; Amprayil, Mathew; Solanki, Nicholas S.; Greenwood, John Edward

    2011-01-01

    Introduction: Wheat bags are therapeutic devices that are heated in microwaves and commonly used to provide relief from muscle and joint pain. The Royal Adelaide Hospital Burns Unit has observed a number of patients with significant burn injuries resulting from their use. Despite their dangers, the products come with limited safety information. Methods: Data were collected from the Burns Unit database for all patients admitted with burns due to hot wheat bags from 2004 to 2009. This was analyzed to determine the severity of the burn injury and identify any predisposing factors. An experimental study was performed to measure the temperature of wheat bags when heated to determine their potential for causing thermal injury. Results: 11 patients were admitted with burns due to hot wheat bags. The median age was 52 years and the mean total body surface area was 1.1%. All burns were either deep dermal (45.5%) or full thickness (54.5%). Ten patients required operative management. Predisposing factors (eg, neuropathy) to thermal injury were identified in 7 patients. The experimental study showed that hot wheat bags reached temperatures of 57.3°C (135.1°F) when heated according to instructions, 63.3°C (145.9°F) in a 1000 W microwave and 69.6°C (157.3°F) on reheating. Conclusions: Hot wheat bags cause serious burn injury. When heated improperly, they can reach temperatures high enough to cause epidermal necrosis in a short period of time. Patients with impaired temperature sensation are particularly at risk. There should be greater public awareness of the dangers of wheat bag use and more specific safety warnings on the products.

  13. Nuclear power as a public issue protection of the public interest

    International Nuclear Information System (INIS)

    Doederlein, J.M.

    1977-01-01

    In evaluating the future role of nuclear power, it should be required to perform a rational and quantitative comparison of power production alternatives on at least the following four parameters: health effects, environmental effects, economy and resource availability. The evaluations should cover all steps from fuel production through waste disposal. We have less detailed knowledge on health effects from air pollution than from radioactivity. However our present body of knowledge clearly indicates that large scale use of nuclear power instead of fossil fuels will save thousands of human lives annually. This is probably one of the most compelling arguments for nuclear power. Clearly a number of irrational political, ethical and emotional factors may be of decisive importance in a large scale choice of power plant types. However an evaluation of rational and quantifiable factors may serve one important function in telling us how many lives, which environmental improvements and what economical advantages we have to sacrifice in order to satisfy such irrational demands. In any case it should be recognized that the public interest is best served by maximum use of the broad knowledge we have on costs and benefits of alternative electric power generation forms. Obviously energy policy is not an area where all questions can be tackled in an absolutely rational and objective way. However a number of absolute restrictions are set by the laws of nature, others by our present technological abilities. Such restrictions can not be changed by wishful thinking, political or otherwise. On the one hand this may serve to define the role of the technological community in making both the nuclear and other more important decisions. On the other hand these are facts which are not fully appreciated by those making a controversial issue of nuclear power. One disturbing aspect of the discussions in many countries, is the plethora of manifestos for or against nuclear power. These are issued

    2008-01-01

    The alignment of the Strip and Pixel Tracker of the Compact Muon Solenoid experiment, with its large number of independent silicon sensors and its excellent spatial resolution, is a complex and challenging task. 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. The future of nuclear power after Sizewell B. 3 v.: v. 1 Economic issues; v. 2 Environmental and safety issues; v. 3 Public perception issues

    International Nuclear Information System (INIS)

    1987-01-01

    The three days of conference proceedings are published in three separate volumes. The first includes 7 papers relating to economic issues - those presented at the Sizewell-B public inquiry and the changes in the economic situation since the inquiry ended. The electricity demand, how this demand is to be met by nuclear and other fuel sources and how energy conservation might be an economic alternative to simply building more generating capacity are all issues discussed. The possible privatisation of the industry is also touched on. Volume two has 8 papers concerned with environmental and safety issues. These include the influence of the Sizewell-B decision on nuclear licensing and reactor safety, the technical and safety aspects of pressurized water reactors (PWR), the roles of British Nuclear Fuels and the United Kingdom Atomic Energy Authority, and radiation protection and effluent discharge control. The six papers in volume 3 look at public perception issues - not only towards nuclear power but towards the public inquiry process. The local authority view, the Friends of the Earth case against the PWR, and technical expertise in the decision process are also topics covered. All the papers are indexed separately. (UK)

  20. Data Quality Monitoring of the CMS Tracker

    International Nuclear Information System (INIS)

    Dutta, Suchandra

    2011-01-01

    The Data Quality Monitoring system for the Tracker has been developed within the CMS Software framework. It has been designed to be used during online data taking as well as during offline reconstruction. The main 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 to fix it. On the other hand any issue with data reconstruction or calibration can be detected during offline processing using the same tool. The monitoring is performed using histograms which are filled with information from raw and reconstructed data computed at the level of individual detectors. Furthermore, statistical tests are performed on these histograms to check the quality and flags are generated automatically. Results are visualized with web based graphical user interfaces. Final data certification is done combining these automatic flags and manual inspection. The Tracker DQM system has been successfully used during cosmic data taking and it has been optimised to fulfill the condition of collision data taking. In this paper we describe the functionality of the CMS Tracker DQM system and the experience acquired during proton-proton collision.

  3. The contribution of safety issues to public perceptions of energy systems

    International Nuclear Information System (INIS)

    Otway, H.J.; Thomas, Kerry

    1978-01-01

    Public opposition is an important consideration for those responsible for energy planning. An attitude model was applied to identify the underlying determinants of public perceptions of five energy systems: nuclear, coal, oil, solar and hydro. Empirical results are reported in which these energy systems were found to be perceived in terms of four basic dimensions: psychological aspects; economics benefits; socio-political implications; environmental and physical safety issues. For the total sample, safety issues made an appreciable contribution to attitudes toward all of the systems except nuclear energy, where it was not significant. A differential analysis of two sub-samples, those respondents PRO and CON nuclear energy, showed that benefits and safety issues were important determinants of PRO attitudes while CON attitudes were primarily due to psychological aspects and concerns about personal and political power. The role of technical information in the formation of public attitudes toward technological policies is discussed [fr

  4. Using a Qualitative Vignette to Explore a Complex Public Health Issue.

    Jackson, Michaela; Harrison, Paul; Swinburn, Boyd; Lawrence, Mark

    2015-10-01

    This article discusses how qualitative vignettes were combined with interviews to explore a complex public health issue; that is, promoting unhealthy foods and beverages to children and adolescents. It outlines how the technique was applied in practice and the combination of vignette-based interviews with a broader approach involving Gadamerian hermeneutics. Twenty-one participants from the public health community and the marketing and food and beverage industries took part in vignette-based interviews between March and September 2012. Overall, the qualitative vignette method afforded an efficient, generally well-received technique that effectively explored the issue of promoting unhealthy foods and beverages to children and adolescents. The vignette provided structure to interviews but allowed certain responses to be investigated in greater depth. Through this research, we argue that qualitative vignettes allow researchers to explore complex public health issues. This article also provides a valuable resource for researchers seeking to explore this technique. © The Author(s) 2015.

    A silicon strip detector has been adopted as baseline technology for the LHCb Inner Tracker system. It consists of nine planar stations covering a cross-shaped area around the LHCb beam pipe. Depending on the final layout of the stations the sensitive surface of the Inner Tracker will be of the order of 14 m 2 . Ladders have to be 22 cm long and the pitch of the sensors should be as large as possible in order to reduce costs of the readout electronics. Major design criteria are material budget, short shaping time and a moderate spatial resolution of about 80 μm. After an introduction on the requirements of the LHCb Inner Tracker we present a description and characterization of silicon prototype sensors. First, laboratory and test beam results are discussed

    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.

    There are several vested interest lies on research publication hence the editorial policy is the sole important factor to control and regulate ethical publications in medical sciences especially on 'conflict of interest' issue. The study was aimed to assess on awareness of 'conflict of interest' issue in medical research and publication among the editorial staff, peer reviewers and authors of Indian medical journals. Total 61 authors who have published research articles recently in Indian medical journals from 2008-2012, 56 peer reviewers who reviewed the manuscripts during same period and 35 editorial board members of various Indian medical journals were assessed by questionnaire and telephone interview regarding their understanding and knowledge on 'conflict of interest' issue for ethical publication. Only seven (12%) of the authors knew about the 'conflict of interest' issue and 11 (19%) of the medical authors have just heard about it. Out of 12% of authors who knew 'conflict of interest' issue only 15% provided that statement to the journals. Among the peer reviewers only 17 (30%) knew about 'conflict of interest' of which 51 (91.5%) stated that they do not bother about this issue while reviewing the manuscripts. But interestingly 42 (75%) of the peer reviewers confessed that they had a bias on the topics written by their friends or students. Among the editorial board members of Indian medical journals only 14 (25%) have any idea on 'conflict of interest issue'. Results clearly shows poor understanding of 'conflict of interest' like important ethical issue among Indian medical scientists or journals.

    Public procurement is one of the areas of the single market where the results of the liberalization drive have not yet measured up to expectations. This communication presents some technical issues versus public acquisition legal issues and suggests ways and means of improving contract award procedures. Procurement area includes the acquisition of goods, services and works, thus assumption not only for purchasing equipment, components, spare-parts or materials, but also hiring of the contractors or consultants to carry out services and works. Procurement is related to the function of management of supply, which encompasses aside range of planning function, coding and classification, stockholding policies, store-keeping, stores accounting, etc. but it is also related to the hiring of contractors or consultants for work or services. As an answer to the challenge of the increasing market globalization it has been developed the ISO quality system, within 9000 family of standards. The very intensive competition for all market clients, either locally or globally, encouraged development of a new concept of quality management systems. Due to its specificity of activity and with respect to the rules and legislation requirements imposed either by the internal Romanian Laws and Regulations or/and by international market rules and constrains, the development, construction and operation of a Nuclear Power Plant shall be performed in a controlled condition and based on specific authorizations obtained by the Owner of the NPP from the Romanian Regulatory Authorities. The experience, accumulated by over 10 years of operation of Cernavoda NPP Unit 1 by our company, demonstrates the high importance of the Quality Management System that imposes the quality of the components installed on the plant, the services and the works developed to assure a safety operation of the nuclear unit, with a strongly dependence by the procurement system established for purchasing of goods, services and

    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.

    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 [1]. 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.

    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 ...

    2012-11-01

    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.

  5. The DOE transportation strategy: Public information, communications network and issue resolution

    International Nuclear Information System (INIS)

    Philpott, R.E.

    1986-01-01

    The OCRWM plans to issue a draft ''comprehensive transportation plan'' in the fall of 1987 that combines the Institutional Plan, the Transportation Business Plan (DOE/RW-0046, January 1986), and a framework for transportation operational procedures. This paper reviews the major elements of the OCRWM's institutional strategy. The OCRWM's strategy for addressing transportation issues relies on the development of public information to foster public understanding and acceptance of program activities and goals, and active communication and interaction with all parties having an interest in the development and operation of the NWPA transportation program. The OCRWM's goal in conducting such activities is to foster cooperative effort in addressing transportation issues, and to focus on communication and constructive interaction rather than conflict

    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.

    Many scientists communicate with the public about risks associated with scientific issues, but such communication may have unintended consequences for how the public views the political orientations and the credibility of the communicating scientist. We explore this possibility using an experiment with a nationally representative sample of Americans in the fall of 2015. We find that risk communication on controversial scientific issues sometimes influences perceptions of the political orientations and credibility of the communicating scientist when the scientist addresses the risks of issues associated with conservative or liberal groups. This relationship is moderated by participant political ideology, with liberals adjusting their perceptions of the scientists' political beliefs more substantially when the scientist addressed the risks of marijuana use when compared with other issues. Conservatives' political perceptions were less impacted by the issue context of the scientific risk communication but indirectly influenced credibility perceptions. Our results support a contextual model of audience interpretation of scientific risk communication. Scientists should be cognizant that audience members may make inferences about the communicating scientist's political orientations and credibility when they engage in risk communication efforts about controversial issues.

  8. Public and political issues in radioactive waste management in the Federal Republic of Germany

    International Nuclear Information System (INIS)

    Neis, A.

    1993-01-01

    The Federal Government's radioactive waste management concept and regulations governing formal public participation in licensing procedures for radioactive waste management facilities are presented. The paper focuses on public and political issues arising from widely diverging views in different social groups on nuclear energy and on radioactive waste management. The resulting conflict between Federal and Laender (Federal constituent states) authorities and the actual course of public participation in a licensing procedure are illustrated with the example of planned final disposal of radioactive waste in the Konrad mine. Major national efforts to overcome the unsatisfying present situation are presented and the role of international consensus is briefly touched. Concluding remarks will particularly justify admissibility and emphasize the need to discuss and eventually decide on radioactive waste management issues regardless of diverging views on nuclear energy

    2016-01-01

    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.

    2014-09-01

    Full Text Available This study examines how Romanian media (through opinion articles in mainstream newspapers, political talk-shows and news broadcasts, sampled between 2011 and 2014 addressed the issue of the labour migration within two European contexts: the economic crisis that began in 2008, having multiple implications for the emigration policies in the EU states, and the opening of the full labour market access to Romanians and Bulgarians starting January 1, 2014. We tested the hypothesis that media discourse instrumentalizes migration in order to legitimize collective identities and public issues, especially those related to identity. Drawing upon the critical discourse analysis and the sociology of public issues, this research argues that the identity categorization practices are based on the dynamics of the migration flows and the economic developments in Europe. Media reframe identity by shifting the angle of approach from the access to the labour market, in terms of liberalization, to the way in which Romanians are perceived in the destination countries, and its extension to Romania’s status within the EU. This redefinition of the public issue occurs through particular types of identity counter-discourses used to deconstruct stereotypical dominant discourses against migrants and Romanians and to revalorize the Romanians working in the EU, as an extension of the (national collective identity. Labour migration becomes a symbolic resource in negotiating the nation image and a political status

    To compare the results of a series of public opinion surveys on experiences with the health care sector in Croatia conducted in the time of elections and to analyze whether political party affiliation had any influence on issues of priority ranking. The surveys were conducted during 2005, 2007, and 2009. They were administered through a Computer Assisted Telephone Interviewing method to representative samples of Croatian population and were statistically weighted according to sex, age, level of education, and political party affiliation. The random sampling of the person within the household was done using the table of random numbers. Health and health care system was the most important issue (58%) during the 2007 parliamentary election and the second most important issue during the 2005 and 2009 elections (46% and 28%). In the 2007 election, health care was viewed as most important by women, respondents with lower education levels, and respondents with lower income. In 2005, the most important health care issues were corruption and lack of funding (45% and 43%, respectively), in 2007 poor organization and lack of funding (43% and 42%, respectively), and in 2009 lack of funding and corruption (51% and 45%, respectively). Health and health care system were consistently among the top two issues in all elections from 2005 to 2009. The top three most important health care sector issues were corruption, poor organization, and lack of funding. This indicates that political parties should include solutions to these issues in their health care policymaking.

    2004-07-01

    The demand for natural gas in a downtown area of Toronto is expected to increase significantly due to the proposed construction of two new generation stations. However, there are few opportunities to locate the pipelines in large urban centers because of the lack of foresight by municipalities and others in preserving corridors for utilities. Enbridge Gas conducted a system planning study to determine the best methods for overcoming public issues that were encountered while planning the route for a NPS 36 inch diameter natural gas pipeline in this urban region. In Ontario, distribution pipelines are regulated by the Ontario Energy Board, whose environmental guidelines for the location, construction and operation of hydrocarbon pipelines require the identification of indirectly affected landowners and detailed analysis of public issues and how they can be resolved. Issues include noise, vibration, dust and traffic. Secondary use of the electric transmission rights-of-way resulted in the identification of several other issues, including aesthetics of the right-of-way and loss of privacy for adjacent residential properties. It was determined that the optimal solution was to parallel a section of existing NPS 30 pipeline running in a north-south right-of-way located east of the Don Valley Parkway. The techniques used to address public issues identified 180 directly affected and 3,200 indirectly affected landowners. The Enbridge study revealed that it is possible to plan a right-of-way through an urban corridor in a manner that is compatible with existing development and that satisfies the general public. 6 figs.

    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.

    The Silicon Strip Tracker (SST) is the intermediate part of the CMS Central Tracker System. SST is based on microstrip silicon devices and in combination with pixel detectors and the Microstrip Gas Chambers aims at performing pattern recognition, track reconstruction and momentum measurements for all tracks with p T ≥2 GeV/c originating from high luminosity interactions at √s=14 TeV at LHC. We aim at exploiting the advantages and the physics potential of the precise tracking performance provided by the microstrip silicon detectors on a large scale apparatus and in a much more difficult environment than ever. In this paper we describe the actual SST layout and the readout system. (author)

  1. LHCb Upgrade: Scintillating Fibre Tracker

    International Nuclear Information System (INIS)

    Tobin, Mark

    2016-01-01

    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.

  2. In Defense of Sparse Tracking: Circulant Sparse Tracker

    KAUST Repository

    Zhang, Tianzhu; Bibi, Adel Aamer; Ghanem, Bernard

    2016-01-01

    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.

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.

    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.

    The Tracker Control System (TCS) is a distributed control software to operate about 2000 power supplies for the silicon modules of the CMS Tracker and monitor its environmental sensors. TCS must thus be able to handle about 10 4 power supply parameters, about 10 3 environmental probes from the Programmable Logic Controllers of the Tracker Safety System (TSS), about 10 5 parameters read via DAQ from the DCUs in all front end hybrids and from CCUs in all control groups. TCS is built on top of an industrial SCADA program (PVSS) extended with a framework developed at CERN (JCOP) and used by all LHC experiments. The logical partitioning of the detector is reflected in the hierarchical structure of the TCS, where commands move down to the individual hardware devices, while states are reported up to the root which is interfaced to the broader CMS control system. The system computes and continuously monitors the mean and maximum values of critical parameters and updates the percentage of currently operating hardware. Automatic procedures switch off selected parts of the detector using detailed granularity and avoiding widespread TSS intervention

    The Korea Institute of Nuclear Safety (KINS), a regulatory expert organization in charge of nuclear safety in Korea, realized that a more fundamental and systematic analysis of activities is needed to actively meet the greater variety of concerns people have and increase the reliability of the results of regulation. Nuclear safety, a highly specialized field, has previously been discussed primarily from the viewpoint of the engineers who deal with the technology, but now 'public trust in nuclear safety' has to be viewed from the standpoint of the general public and from the socio-cultural perspective. Specific measures must be taken to examine which factors affect public trust and how we can secure and reproduce those factors to gain it. Also, an efficient system for incorporating public trust in nuclear safety must be established. In this study, various case studies were examined to identify the factors that affect public trust in nuclear safety. First, nuclear safety laws and information disclosure systems of major countries were examined by investigating data and conducting in-depth interviews. To explore a public framework concerning nuclear safety, big data of social media were analyzed. Also, Q methodology was used to analyze the risk schemata of the opinion leaders living in areas near nuclear power plants. Several surveys were conducted to analyze the amount of trust the public had in nuclear safety as well as their awareness of nuclear safety issues. Based on these analyses, factors affecting public trust in nuclear safety were extracted, and measures to build systems incorporating public trust in nuclear safety were proposed. This study addresses the public trust in nuclear safety on condition that the safety is ensured technically and mechanically.

  11. How public issues shape environmental restoration plans - experiences with Colorado UMTRA projects

    1991-01-01

    Federal environmental restoration plans are being significantly impacted by open-quotes grassrootsclose quotes public pressure and by community demands, some of which have little relation to the technical standards of remediation and which go well beyond authorizing legislation. These demands often represent significant additional project costs. A review of Uranium Mill Tailings Remedial Action (UMTRA) Program experiences in Colorado suggests that the more serious open-quotes grassrootsclose quotes issues associated with remediation rarely diminish and, in fact, will intensify over time. This presents program administrators with the dilemma of attempting to adhere to program mandates and keep projects within budget, while at the same time trying to be responsive to community concerns. Such high-profiled community debates have the ability to delay remediation and even jeopardize important projects. After prolonged public debate, when it becomes clear an issue will not dissipate, project officials may be forced to meet certain community demands. Often, this results in not only increased costs, but a loss of public confidence in clean-up efforts. Evidence also suggests, however, that when critical public issues can be identified and addressed before they become overly contentious, significant problems and controversy can be avoided; but, the situation is made difficult because project officials often lack the policy guidance to determine which, if any, community demands should be addressed and to what extent they should be met. The adoption of several key public policy principles by program administrators will provide a greater ability to address community demands in a timely and successful manner

    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.

    After more than 3 years of successful operation at 2 the LHC, we report on the operation and performance of the Semi-Conductor Tracker (SCT) functioning in a high luminosity, 4 high radiation environment. The SCT is part of the inner tracking system of the ATLAS 6 experiment at CERN and is constructed of 4088 silicon detector modules for a total of 6.3 million strips. We find 99.3% of the 8 SCT modules are operational, noise occupancy and hit efficiency exceed the design specifications; the alignment is very close to 10 the ideal to allow on-line track reconstruction and invariant mass determination. We will report on the operation and performance 12 of the detector including an overview of the issues encountered. The observables employed to monitor online and offline the 14 quality and the performance of the data acquired by the SCT will be described and discussed.

    2018-01-10

    Following Obergefell v. Hodges, same-sex marriage remains controversial and anti-LGBT state legislation has been passed, which raises questions about whether the Supreme Court's ruling may have created a backlash. We use data from two waves of a general population survey of Nebraskans conducted before and after the decision to answer three questions. First, we test three theories of how the court decision influenced public opinion. We find that support for same-sex marriage was significantly higher following the ruling, suggesting that there was not a backlash to it. Second, we assess whether people perceive that the court accurately reflects the public's opinion. We find that people who favor same-sex marriage are more likely to think that the ruling refects public opinion very well; those who oppose same-sex marriage are more likely to think that the ruling does not at all reflect public opinion. Third, we examine the association between discussing gay rights and support for same-sex marriage, finding that those who talk about LGB issues very often are more likely to favor same-sex marriage. We discuss the implications of these findings in relation to two of the themes of this special issue: the influence of marriage equality on Americans' understandings of marriage and the impact of marriage equality on future LGBT activism.

    2013-04-01

    The Copernicus data publication journal Earth System Science Data (ESSD) represents an important and unique (and by no means final!) step forward in the larger world of data publication. Working with authors, reviewers, editors and data centres, ESSD has successfully produced many high-quality data publications across a wide variety of scientific disciplines, for individual data sets, multiple data sets as the product of scientific consortia and in special issues coordinated with other science journals. The ESSD success also exposes issues and challenges for present and future data publication, particularly around the topic and implementation of persistent identifiers. • As ESSD encourages redundant data sets across multiple data centres for access and archive purposes, how will DOIs be employed to accurately point to those distributed or replicated data? How can authenticity and integrity be verified? • How can or should object identifiers be employed in pointing from raw to quality-controlled and finally derived data processing levels; how can we designate or distinguish among these, particularly as those terms vary substantially among, for example, geophysical and ecological communities? Likewise, how to distinguish an auto-generated data product (e.g a species identification from GBIF) from a high-effort expertly reviewed data product (e.g. an ESSD publication)? • For a growing number of ESSD data publications with expected annual or periodic revisions and updates, how should data journals' and the repositories' use of persistent identifiers best record the subsequent versions, extensions or corrections? • As published data sets become a valued part of high profile science, with attendant deadlines, announcements and publicity, do the various DOI policies and minting practices among cooperating publishers, data centres and journals represent a help or a hindrance? These questions evolve directly from increasing interest in and activity by ESSD and, as

    This document is proposed by a work-group which gathered the IRSN, public local information commissions and the French Health Survey Institute (InVS). It is designed to be a methodological document on the benefits and limits of health analysis tools with respect to real situations. The first part discusses the implementation of a public health survey, its approach, its modalities and how its results are published. The second part deals with methodological issues for the definition of the specifications of a public health survey, and its protocol. Thus, it discusses how releases in the environment are to be addressed (releases from nuclear installations and from other activities involving radioactivity), the different pathologies to be studied, the existing health data and survey tools (mortality and cancer incidence data, medical-administrative data), and the possible survey types (descriptive or analytical epidemiological surveys) and their limitations

    This case study of the public policy implications of introducing a new technology in radiology, namely, low-osmolar contrast media (LOCM), raises the issues of whether and how to place appropriate limits on new technologies. Although these contrast media represent small episodic costs, they may add up to an aggregate expenditure of nearly $1 billion per year if used for all contrast injections. As a result, this technology raises a number of important medical, economic, legal, and public policy questions. The cost-effectiveness analysis and an analysis of the medical evidence suggest that LOCM should be limited to high-risk patients. The authors discuss in this article how the legal system might respond to such limitations, and they consider various public policy options for adopting restrictions on use. They conclude that the medical profession should take the lead in developing protocols for appropriate assessment, reimbursement, and use of LOCM

    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. The 200 μm thick sensor is divided into 18000 300 μm 300 μm pixels bump-bounded to ten independent read-out chips. The chips use an end-of-column architecture and rely on time-over- threshold discriminators. A station can handle a crossing rate of 750 MHz. Microchannel cooling technology will be used to cool the assembly. It allows us to keep the sensor close to 0 C with 130 μm of silicon in the beam area. The sensor and read-out chip performance were validated using a 45 pixel demonstrator with a laser test setu...

    In order to use thin scintillating fiber (diameter 500 micron) as a particle tracking detector, we have developed a method to construct precise multi-layer scintillating fiber sheets. We have also developed dedicated machines for this purpose. This paper presents the details of the method and the machines. Using these machines, we have produced fiber sheets for CERN WA95/CHORUS, which intend to detect a neutrino oscillation in the νμ-ντ channel using Hybrid Emulsion Set-up. Fiber Trackers are used as a vertex detector which support the neutrino event location in the nuclear emulsion target. (author)

    The main task of the Target Tracker detector of the long baseline neutrino oscillation OPERA experiment is to locate in which of the target elementary constituents, the lead/emulsion bricks, the neutrino interactions have occurred and also to give calorimetric information about each event. The technology used consists in walls of two planes of plastic scintillator strips, one per transverse direction. Wavelength shifting fibres collect the light signal emitted by the scintillator strips and guide it to both ends where it is read by multi-anode photomultiplier tubes. All the elements used in the construction of this detector and its main characteristics are described.

  1. Addressing public concerns about ethical and environmental issues in the discussion on nuclear waste management

    International Nuclear Information System (INIS)

    Luthi, A.

    1996-01-01

    According to Swiss Federal Law, the producers of radioactive waste are responsible for its safe disposal. The government, therefore, plays a relatively modest role in the public debate on nuclear waste management. Whenever asked to express an opinion, it tries to inform openly. Active public relations campaigns are led by the National Co-operative for the Disposal of Radioactive Waste (NAGRA). The operators of nuclear power plants are ready to compensate the siting community and its Canton for services rendered in the public interest. An important way to deal with ethical and environmental issues is the inclusion of opponents in every step of the time-consuming licensing procedure. This paper discusses the upcoming vote on a concession for a low and intermediate-level waste repository for which NAGRA is actively preparing. NAGRA's public relations work is based on recognition of the fact that the only way to diminish fear and gain credibility is to inform openly and regularly over many years, and to show that results achieved are based on serious, careful and transparent scientific work. Another aspect of radioactive waste management communication lies in the explanation of the ethics of 'inter-generational' and 'intra-generational' equity. Compensation will never make up for lack of safety. The ways in which the public voices its views are discussed, as well as the concept of seeking the co-operation of opponents in working groups.

    1989-06-01

    In June 1988 the Nuclear Regulatory Commission (NRC) issued for public comment the proposed Revision 2 of the Standard Review Plan (SRP) Sections 2.5.2, 3.7.1, 3.7.2. and 3.7.3. Comments were received from six organizations. Brookhaven National Laboratory (BNL) was requested by NRC to provide expert consultation in the seismic and soil-structure interaction areas for the review and resolution of these comments. For this purpose, a panel of consultants was established to assist BNL with the review and evaluation of the public comments. This review was carried out during the period of October 1988 through January 1989. Many of the suggestions given in the public comments were found to be significant and a number of modifications to appropriate SRP sections are recommended. Other public comments were found to have no impact on the proposed Revision 2 of the SRP. Major changes are recommended to the SRP sections dealing with (a) Power Spectral Density (PSD) and ground motion requirements and (b) soil-structure interaction requirements. This report contains specific recommendations to NRC for resolution of the public comments made on the proposed Revision 2 of the SRP

    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

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

    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

    Since the invention and dissemination of domestic laser pointers, observing optical phenomena is a relatively easy task. Any student can buy a laser and experience at home, in a qualitative way, the reflection, refraction and even diffraction phenomena of light. However, quantitative experiments need instruments of high precision that have a relatively complex setup. Fortunately, nowadays it is possible to analyse optical phenomena in a simple and quantitative way using the freeware video analysis software ‘Tracker’. In this paper, we show the advantages of video-based experimental activities for teaching concepts in optics. We intend to show: (a) how easy the study of such phenomena can be, even at home, because only simple materials are needed, and Tracker provides the necessary measuring instruments; and (b) how we can use Tracker to improve students’ understanding of some optical concepts. We give examples using video modelling to study the laws of reflection, Snell’s laws, focal distances in lenses and mirrors, and diffraction phenomena, which we hope will motivate teachers to implement it in their own classes and schools.

    The ATLAS detector (CERN,LHCC,94-43 (1994)) is designed to study a wide range of physics at the CERN Large Hadron Collider (LHC) at luminosities up to 10 34 cm -2 s -1 with a bunch-crossing rate of 40 MHz. The Semiconductor Tracker (SCT) forms a key component of the Inner Detector (vol. 1, ATLAS TDR 4, CERN,LHCC 97-16 (1997); vol. 2, ATLAS TDR 5, CERN,LHCC 97-17 (1997)) which is situated inside a 2 T solenoid field. The ATLAS Semiconductor Tracker (SCT) utilises 4088 silicon modules with binary readout mounted on carbon fibre composite structures arranged in the forms of barrels in the central region and discs in the forward region. The construction of the SCT is now well advanced. The design of the SCT modules, services and support structures will be briefly outlined. A description of the various stages in the construction process will be presented with examples of the performance achieved and the main difficulties encountered. Finally, the current status of the construction is reviewed

    Pricing policies such as taxes and subsidies are important tools in preventing and controlling a range of threats to public health. This is particularly so in tobacco and alcohol control efforts and efforts to change dietary patterns and physical activity levels as a means of addressing increases in noncommunicable diseases. To understand the potential impact of pricing policies, it is critical to understand the nature of price elasticities for consumer products. For example, price elasticities are key parameters in models of any food tax or subsidy that aims to quantify health impacts and cost-effectiveness. We detail relevant terms and discuss key issues surrounding price elasticities to inform public health research and intervention studies. PMID:24028228

This is particularly so in tobacco and alcohol control efforts and efforts to change dietary patterns and physical activity levels as a means of addressing increases in noncommunicable diseases. To understand the potential impact of pricing policies, it is critical to understand the nature of price elasticities for consumer products. For example, price elasticities are key parameters in models of any food tax or subsidy that aims to quantify health impacts and cost-effectiveness. We detail relevant terms and discuss key issues surrounding price elasticities to inform public health research and intervention studies.

    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.

  12. Non-linear behavior of public opinion on the issues regarding inhabitants' polls

    International Nuclear Information System (INIS)

    Ohnishi, Teruaki; Suganuma, Jyun-ichi

    2003-01-01

    The observed change of public attitude around the time of inhabitants' poll in Japan was compared with model calculation to investigate its non-linear behavior. Two inhabitants' polls regarding nuclear issues, the approval and disapproval of the construction of Maki nuclear station, and of the MOX fuel use at Kashiwazaki-Kariwa nuclear station, were considered together with the poll on the reconstruction of the tenth weir in Yoshino river carried out in Tokushima. By using a mathematical model such that the individual attitude is mainly subject to two factors of the information environment and the mutual communication between the public, it was found that the change and the unification of public attitude around the time of inhabitants' poll can be interpreted as a manifestation of self-organization resulted from the cooperative phenomenon of those two factors. Moreover, it was also found that the abrupt change of public attitude just before the poll can be interpreted as a result of positive feedback of the information environment formed by the various types of propaganda activities to the attitude change, though the extent of such non-linear effects differs from case to case.

  13. [Citizenship and modernity: the emergence of the social issue on the public agenda

    1997-04-01

    The guiding thread of this article is the inclusion of the so-called "social issue" on the public agenda from modernity through its more current developments. The study seeks to demonstrate that one of the meanings of modernity is precisely the radical inversion of the meaning of public and private, providing for the broadening of public space. Far from being associated with a given bourgeois capitalist model, modernity thus projects itself as a reinvention of rights, citizenship, and contemporary democratic experience. Over this long course, the individualization process has been seen as a crucial factor for understanding both the ideology of modern societies and - paradoxically - the very emergence of social sciences. The individualist concept, emphasizing the specificity of modern representation of the social sphere, i.e., its characteristic as a self-instituting society, allows for a broadened understanding of the public domain. In this sense, the ideological polarization between liberal conceptions (favoring individualism) and Marxist ones (linked to holistic representations of the social sphere) should be reviewed, since this polarization has repercussions on the very analytical tools used by social sciences.

  16. CMS Silicon Strip Tracker Performance

    CERN Document Server

    Agram, Jean-Laurent

    2012-01-01

    The CMS Silicon Strip Tracker (SST), consisting of 9.6 million readout channels from 15148 modules and covering an area of 198 square meters, needs to be precisely calibrated in order to correctly reconstruct the events recorded. Calibration constants are derived from different workflows, from promptly reconstructed events with particles as well as from commissioning events gathered just before the acquisition of physics runs. The performance of the SST has been carefully studied since the beginning of data taking: the noise of the detector, data integrity, signal-over-noise ratio, hit reconstruction efficiency and resolution have been all investigated with time and for different conditions. In this paper we describe the reconstruction strategies, the calibration procedures and the detector performance results from the latest CMS operation.

    In recent years, silicon photomultipliers (SiPMs) have been proposed as a new kind of readout device for scintillating detectors in many experiments. A SiPM consists of a matrix of parallel-connected pixels, which are independent photon counters working in Geiger mode with very high gain ({approx}10{sup 6}). This contribution presents the use of an array of eight SiPMs (manufactured by FBK-irst) for the readout of a scintillating bar tracker (a small size prototype of the Electron Muon Ranger detector for the MICE experiment). The performances of the SiPMs in terms of signal to noise ratio, efficiency and time resolution will be compared to the ones of a multi-anode photomultiplier tube (MAPMT) connected to the same bars. Both the SiPMs and the MAPMT are interfaced to a VME system through a 64 channel MAROC ASIC.

    T, Iizawa; The ATLAS collaboration

    2014-01-01

    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...

    Full Text Available This mixed method study sought to explore the issues that faced secondary teachers in a rural central Georgia public high school when attempting to implement a multicultural education program.  The key issues of this study centered on the teachers’ multicultural education training and the school’s multicultural education program. Data were gathered from a total of thirty randomly chosen teachers in the Social Studies, Math and English departments at the school. Twenty-five of the thirty teachers received a hard copy four question Likert scale survey to complete. The remaining 5 participants took part in face-to-face interviews discussing six open-ended questions.  The findings pointed to several issues facing the teachers such as the lack of an officially implemented multicultural education program, the lack of support from school administrators, no in-service training available for teachers, parental and student misapprehension, and a lack of an officially defined policy on implementation and support of a multicultural education program from administrators locally and district-wide.

    Public Private Partnership (PPP) in Malaysia aims to stimulate economic growth and overcome the weakness of conventional system. Over the years, many critics have been reported along the massive growth of PPP project development. Within that context, this study provides a review of issues and challenges for PPP pertaining to project performance in Malaysia. The study also attempts to investigate four performance measurement models around the globe as a basis for improvement of PPP in Malaysia. A qualitative method was used to analyse literature review from previous published literatures while comparative analysis was carried out within the models to identify their advantages and disadvantages. The findings show that the issues and challenges occurred were related to human, technical and financial factor that could hinder the implementation of PPP project in Malaysia. From the analysis, KPIs, guideline / framework, risk allocation, efficiency & flexibility are perceived as dominant issues. Finally, the findings provide an informed basis on the opportunity areas to be considered for improvement in order to achieved project effectiveness.

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

    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.

    Farmer, P.R.; Dunnicliffe, C.J.

    1988-01-01

    Issues on PWR safety transient analysis that were discussed at the Sizewell B Public Inquiry are presented. The Public Inquiry was set up by the UK Government under an Inspector, Sir Frank Layfield, to examine all aspects of the construction, safety and operation of a 1200 MW(e) PWR on the Sizewell site. The terms of reference were broad ranging, and the constitution of the Inquiry was to make a recommendation under three Acts of Parliament which apply to the construction and operation of nuclear electrical plant. The Inquiry also covered local planning aspects, which are the responsibility of the Local Authority - in this case the Suffolk County Council. The Inspector examined and made recommendations on the safety of the Station, but consideration by Public Inquiry is outside the formal safety and licensing process, which is the business of the Utility (the CEGB) and the Nuclear Installations Inspectorate (the NII). The paper therefore takes a broader look at the question of safety, dealing with the licensing process, the requirements of the safety case and the forward strategies adopted by the CEGB in terms of research and development. This is considered for transient analysis, and the aim is to set the discussions and conclusions of the Public Inquiry into their proper context with regard to nuclear safety in the UK. The Inquiry went into some depth on the topic of LOCA, as an example of safety analysis. In the summary of the evidence and cross-examination the Inspector accepted the adequacy of the LOCA safety case without major reservations, and was satisfied further work in progress would resolve any residual criticisms. In particular support was given for the CEGB commitment to the development and use of more physically realistic calculational methods

    A public inquiry has been set up to examine the planning application made by the Central Electricity Generating Board (CEGB) for the construction of a 1200 MW Pressurized Water Reactor power station at Hinkley Point (Hinkley Point ''C'') in the United Kingdom, adjacent to an existing nuclear power station. The CEGB evidence to the Inquiry on local site related issues begins by setting the proposed development within the context of local authority planning policies for the area. The implications of the development in terms of overall land needs, construction, access, buildings and works both temporary and permanent, are described. Environmental impacts, aesthetic and socio-economic factors are considered including possible effects on agriculture, nature conservation, water supply, transport and employment. (UK)

    This paper describes the results of an experiment aiming at communicating radioactive waste and radioactive pollution issues to the public. The target group was high school students of Belo Horizonte, Minas Gerais, Brazil and the experiment was carried out during their visit to Exponuclear Fair parallel to the VII Brazilian General Conference on Nuclear Energy, in September, 1999. The students were presented two 3D interactive panels at the Poster section of the event and attended a 10 minutes speech on the subjects. Three months latter, they were invited to answer a questionnaire. Their responses allowed the authors to evaluate the efficiency of the communication in terms of knowledge acquisition and risk perception. (author)

  10. Patents and Publics: Engaging Museum Audiences with Issues of Ownership and Invention

    Directory of Open Access Journals (Sweden)

    James F. Stark

    2015-04-01

    Full Text Available It is all very well to note the hyperbole about patents and ‘intellectual property’ in the recent battles between technology companies such as Apple, Samsung and HTC. But how can museums productively use collection items marked with a patent beyond workaday tasks of identification and cataloguing? We argue that information on patents can enhance visitors’ critical engagement with museum displays; complex ownership claims and counter-claims in patent disputes can underpin lively narratives based around museum objects. Asking why some objects and not others were patented, and how historical consumers responded to that status of ‘patented’ enables us to look at these objects afresh. In particular we analyse the responses of public consultation groups to patenting in the medical trade, as well as the engagement of museum staff with these issues. Such consultation processes offer information that can be used to enhance museum displays with engaging narratives of ownership and invention.

    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.

    2017-12-01

    Full Text Available This work consists in a research on the inclusion of environmental matters in two degree courses of Chemistry in a public university. We started from the idea that discussing environmental issues in the academic context, in particular in the context of the Degree in Chemistry, is being very necessary nowadays, due to what society is going through, which is what we call "environmental crisis". Our main objective was to identify how the formation of the Chemistry teacher in these two courses has contemplated the inclusion of environmental issues as defined in the guidelines of official documents which they are subjected to. To structure all our discussion, we had as the theoretical background the production cycle of the curriculum policies developed by Ball and Bowe (1992, establishing this research in three main contexts presented by them (context influence, text production context and practice context. Therefore, a documental research in the national curriculum guidelines that drive the training of teachers / Chemistry teachers and educational projects of each course was conducted as well as interviews with coordinators and teachers of these courses, trying to understand the inclusion of discussions and questions that lead to an environmentally oriented education.

    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...

    2010-01-01

    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. This was followed by collisions at the unprecedented energy of 7 TeV in March 2010. The SemiConductor Tracker (SCT) is a precision tracking device in ATLAS made up from silicon micro-strip detectors processed in the planar p-in-n technology. The signal from the strips is processed in the front-end ASICs working in binary readout mode. Data is transferred to the off-detector readout electronics via optical fibers. The completed SCT has been installed inside the ATLAS experiment. Since then the detector was operated for two years under realistic conditions. Calibration data has been taken and analysed to determine the performance of the system. In addition, extensive commissioning with cosmic ray events has been performed both with and without magnetic field. The sensor behaviour in magnetic field was studied by measurements of the Lorentz angle. After ...

    Potamianos, Karolos Jozef; The ATLAS collaboration

    2018-01-01

    The Fast Tracker (FTK) is a hardware upgrade to the ATLAS trigger and data acquisition system providing global track reconstruction to the High-Level Trigger (HLT) with the goal to improve pile-up rejection. The FTK processes incoming data from the Pixel and SCT detectors (part of the Inner Detector, ID) at up to 100 kHz using custom electronic boards. ID hits are matched to pre-defined track patterns stored in associative memory (AM) on custom ASICs and data routing, reduction and parameter extraction is achieved with processing on FPGAs. With 8000 AM chips and 2000 FPGAs, the FTK provides enough resources to reconstruct tracks with transverse momentum greater than 1 GeV/c in the whole tracking volume with an average latency below 100 microseconds at collisions intensities expected in Runs II and III of the LHC. The tracks will be available at the beginning of the trigger selection process, which allows development of pile-up resilient triggering strategies to identify b-quarks and tau-leptons, as well as pr...

    2017-01-01

    From 2010 to 2012 the Large Hadron Collider (LHC) operated at a centre-of-mass energy of 7 TeV and 8 TeV, colliding bunches of particles every 50 ns. During operation, the ATLAS trigger system has performed efficiently contributing to important results, including the discovery of the Higgs boson in 2012. The LHC restarted in 2015 and will operate for four years at a center of mass energy of 13 TeV and bunch crossing of 50 ns and 25 ns. These running conditions result in the mean number of overlapping proton-proton interactions per bunch crossing increasing from 20 to 60. The Fast Tracker (FTK) system is designed to deliver full event track reconstruction for all tracks with transverse momentum above 1 GeV at a Level-1 rate of 100 kHz with an average latency below 100 microseconds. This will allow the trigger to utilize tracking information from the entire detector at an earlier event selection stage than ever before, allowing for more efficient event rejection. To achieve this goal the system uses a parallel ...

    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.

    India is becoming one of the hubs of clinical research. Commensurate with these advances, the government funding for biomedical research in thrust areas is also increasing. The Indian Council of Medical Research (ICMR), Department of Biotechnology (DBT), Department of Science and Technology (DST) are some of the government organizations which provide financial support for various research projects. The results of the funded research projects are published in various international journals. Most of these journals have an access to paid subscribers only. Hence it is unethical to use the research grants from government (people's money) and not allow the scientific community free access to the results of the study. To tackle such issues, these agencies should sign the Berlin declaration and create open access repositories. A public access policy should be formulated and listed in JULIET. The funding bodies in India should also join Pubmed Central (PMC) to form PMC India so that every investigator who has received grants would submit the full text of the paper published from his study and these can be made freely accessible to everyone. Universities and research institutions should also develop institutional open access repositories. The public access policy has definitive advantages and should be implemented.

    1997-01-01

    Attempting to incorporate new technology into an existing environment is often very difficult. The problems are lengthy to resolve, wrought with confusion and seldom turn out like anyone expected. This document represents an overview of one such attempt. It outlines the general areas of concern which could be affected by a transition, and potential problems that may be encountered as a result of the effort. Over the past several decades, many local, state and federal agencies are pressing for more efficient use of frequency spectrums. The urgency of this issue has grown due to the demands of several groups wanting access to these channels for commercial use. Pager systems, cellular telephones, radio systems for private businesses all demand more space. Public safety agencies are starting to fear their needs will diminish in importance as the available channel spectrums are consumed by commercial ventures. How to share these channels, purchase appropriate equipment to meet your needs, and stay within a reasonable budget are not easy tasks. Public safety agencies who rely on communication networks in the performance of their jobs also know why encryption is important. Protecting the rights of citizens as police exchange information over the air, maintaining the integrity of an investigation and officer safety are all concerns police must address each time they use a radio.

    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

    The World Council of Churches favors the widest possible discussion of nuclear power issues with the immediate purpose of raising the level of public awareness of the social, political, and technical risks that are inevitably associated with the large-scale and accelerating adoption of nuclear power generation. Its general position on nuclear energy is presented as follows. (A) The availability of nuclear energy is a controversial feature of today's world in that it affords the opportunity to provide a large fraction of the world's energy needs, counter-balanced by the exceptional nature of the risks involved, and other problems related to the employment of large-scale, capital-intensive high technology. (B) The maturity of the nuclear energy system is not yet such as to justify its worldwide application; the consequences of large-scale expansion of nuclear energy production are still relatively poorly understood and require further assessment. (C) The rights of access to nuclear technology should be preserved to the extent that the nuclear ''haves'' may not deny the nuclear ''have nots'' by any form of exclusive consultation. (D) There should be sufficient discussion of the factors governing access to nuclear technology to bring all nations to a new awareness of its risks and uncertainties as well as its opportunities; and the collective responsibility for monitoring and administering safeguards should reside with the IAEA rather than with individual governments. (E) Public confidence in the use of nuclear energy, seriously shaken in recent years, can be revived only by the widest possible public discussion of the technical options and of the value judgements underlying present patterns of energy consumption.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    2005-01-01

    The task of tracking charged particles in energy frontier collider experiments has been largely taken over by solid-state detectors. While silicon microstrip trackers offer many advantages in this environment, large silicon trackers are generally much more massive than their gaseous counterparts. Because of the properties of the machine itself, much of the material that comprises a typical silicon microstrip tracker can be eliminated from a design for the ILC. This realization is the inspiration for a tracker design using lightweight, short, mass-producible modules to tile closed, nested cylinders with silicon microstrips. This design relies upon a few key technologies to provide excellent performance with low cost and complexity. The details of this concept are discussed, along with the performance and status of the design effort

  15. 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...

    The international Muon Ionization Cooling Experiment (MICE) collaboration will carry out a systematic investigation of the ionization cooling of a muon beam. An ionization cooling channel is required to compress the phase-space volume occupied by the muon beam prior to acceleration in the baseline conceptual designs for both the Neutrino Factory and the Muon Collider. Muons entering and leaving the cooling channel will be measured in two solenoidal spectrometers, each of which is instrumented with a scintillating-fibre tracker. Each tracker is composed of five planar scintillating fibre stations, each station being composed of three planar layers of 350 micron scintillating fibres. The devices will be read out using the Visible Light Photon Counters (VLPCs) developed for use in the D0 experiment at the Tevatron. The design of the system will be presented along with the status of the tracker-construction project. The expected performance of prototypes of the full tracker will be summarised.

  19. PERSISTENT ORGANIC POLLUTANTS IN HUMANS AND WILDLIFE: EMERGING ISSUES FOR ENVIRONMENTAL AND PUBLIC HEALTH

    Directory of Open Access Journals (Sweden)

    Aldo Pacheco Ferreira

    2013-08-01

    Full Text Available Persistent organic pollutants persevere in the environment for a long time, are toxic to humans and/or wildlife, and have a resilient propensity to bioaccumulate in the food chain. Due to its chemical stability, their lipid solubility, and its ubiquitous prevalence in environmental, these pollutants are disposed to long-range transport. The success of modern societies is in part based on extensive achievements of chemistry with a systematic development of products in medicine, agriculture, and in almost all manufacturing industry sectors and materials for daily use. Although, these chemicals unequivocally contribute to the quality of life for billions of human beings, however, the negative impacts to environment and health are an important issue for ostensible monitoring. Social and environmental benefits should not be ignored, in spite of economic forces.The recognition that prevention is the best method to mitigate the risk of diseases to public health related to the environment, mainly driven by technological development, becomes essential the individuation and quantification of toxicological endpoints for systematic monitoring of these emerging pollutants.

  20. Modern environmental health hazards: a public health issue of increasing significance in Africa.

    Nweke, Onyemaechi C; Sanders, William H

    2009-06-01

    Traditional hazards such as poor sanitation currently account for most of Africa's environmentally related disease burden. However, with rapid development absent appropriate safeguards for environment and health, modern environmental health hazards (MEHHs) may emerge as critical contributors to the continent's disease burden. We review recent evidence of human exposure to and health effects from MEHHs, and their occurrence in environmental media and consumer products. Our purpose is to highlight the growing significance of these hazards as African countries experience urbanization, industrial growth, and development. We reviewed published epidemiologic, exposure, and environmental studies of chemical agents such as heavy metals and pesticides. The body of evidence demonstrates ongoing environmental releases of MEHHs and human exposures sometimes at toxicologically relevant levels. Several sources of MEHHs in environmental media have been identified, including natural resource mining and processing and automobile exhaust. Biomonitoring studies provided direct evidence of human exposure to metals such as mercury and lead and pesticides such as p,p'-dichlorodiphenyltrichloroethane (DDT) and organophosphates. Land and water resource pollution and industrial air toxics are areas of significant data gaps, notwithstanding the presence of several emitting sources. Unmitigated MEHH releases and human exposure have implications for Africa's disease burden. For Africans encumbered by conditions such as malnutrition that impair resilience to toxicologic challenges, the burden may be higher. A shift in public health policy toward accommodating the emerging diversity in Africa's environmental health issues is necessary to successfully alleviate the burden of avoidable ill health and premature death for all its communities now and in the future.

    An introduction to the physics prospects of future experiments at the CERN Large Hadron Collider (LHC) will be given, along with the rather stringent requirements placed on their detectors by the LHC environment. Emphasis will be placed upon the particle tracking detectors, and the particular problem of their readout systems. The novel analogue optical readout scheme chosen by the Compact Muon Solenoid (CMS) experiment at the LHC will provide the basis for the thesis. The reasons for preferring analogue optical data transmission in CMS will be given, leading to a description of a generic optical readout scheme and its components. The particular scheme chosen by CMS makes as wide as possible use of commercially available components. These will be given greatest importance, with descriptions of component operation and characteristics pertinent to successful readout of the CMS tracker within the constraints of the LHC environment. Of particular concern is the effect of the LHC's harsh radiation environment on the operational characteristics of the readout system and its components. Work on radiation effects in components of the CMS tracker optical readout system will be described. This work includes the effects of ionising (gamma photon) and particle (neutron, proton, pion) irradiation on the operational characteristics and reliability of laser diodes, photodiodes, and optical fibres. System integration issues are discussed in the context of the long-term operation of the full CMS tracker readout system under laboratory conditions. It will be shown that system stability can be maintained even under widely varying ambient conditions. (author)

    Context Gender minority people who are transgender or gender nonconforming experience widespread discrimination and health inequities. Since 2012, Massachusetts law has provided protections against discrimination on the basis of gender identity in employment, housing, credit, public education, and hate crimes. The law does not, however, protect against discrimination in public accommodations (eg, hospitals, health centers, transportation, nursing homes, supermarkets, retail establishments). For this article, we examined the frequency and health correlates of public accommodations discrimination among gender minority adults in Massachusetts, with attention to discrimination in health care settings. Methods In 2013, we recruited a community-based sample (n = 452) both online and in person. The respondents completed a 1-time, electronic survey assessing demographics, health, health care utilization, and discrimination in public accommodations venues in the past 12 months. Using adjusted multivariable logistic regression models, we examined whether experiencing public accommodations discrimination in health care was independently associated with adverse self-reported health, adjusting for discrimination in other public accommodations settings. Findings Overall, 65% of respondents reported public accommodations discrimination in the past 12 months. The 5 most prevalent discrimination settings were transportation (36%), retail (28%), restaurants (26%), public gatherings (25%), and health care (24%). Public accommodations discrimination in the past 12 months in health care settings was independently associated with a 31% to 81% increased risk of adverse emotional and physical symptoms and a 2-fold to 3-fold increased risk of postponement of needed care when sick or injured and of preventive or routine health care, adjusting for discrimination in other public accommodations settings (which also conferred an additional 20% to 77% risk per discrimination setting endorsed

    Since 2012, Massachusetts law has provided legal protections against discrimination on the basis of gender identity in employment, housing, credit, public education, and hate crimes. The law does not protect against discrimination based on gender identity in public accommodations settings such as transportation, retail stores, restaurants, health care facilities, and bathrooms. A 2013 survey of Massachusetts transgender and other gender minority adults found that in the past 12 months, 65% had experienced public accommodations discrimination since the law was passed. This discrimination was associated with a greater risk of adverse emotional and physical symptoms in the past 30 days. Nondiscrimination laws inclusive of gender identity should protect against discrimination in public accommodations settings to support transgender people's health and their ability to access health care. Gender minority people who are transgender or gender nonconforming experience widespread discrimination and health inequities. Since 2012, Massachusetts law has provided protections against discrimination on the basis of gender identity in employment, housing, credit, public education, and hate crimes. The law does not, however, protect against discrimination in public accommodations (eg, hospitals, health centers, transportation, nursing homes, supermarkets, retail establishments). For this article, we examined the frequency and health correlates of public accommodations discrimination among gender minority adults in Massachusetts, with attention to discrimination in health care settings. In 2013, we recruited a community-based sample (n = 452) both online and in person. The respondents completed a 1-time, electronic survey assessing demographics, health, health care utilization, and discrimination in public accommodations venues in the past 12 months. Using adjusted multivariable logistic regression models, we examined whether experiencing public accommodations discrimination in

    2014-05-01

    This paper considers Gavin Mooney's contributions to the research literature on inclusiveness in global and public health issues. Much of his contribution in this area stems from engaging with Indigenous people, which cemented his conviction that it is important to recognise the heterogeneity of groups in society, especially in relation to cultural differences. He believed that in order to develop appropriate equitable and efficient health and related policies, the preferences of citizens should be elicited. While this could feed into very specific policy decisions, such as how to allocate available resources within a particular community, more generally, community preferences should determine the core values that underpin a health system. He proposed that these values be documented in a 'constitution' and serve as the basis on which policy-makers and health managers make decisions. Preference elicitation has value in itself, as procedural justice allows for self-determination and contributes to empowerment. Further, engagement by citizens in deliberative processes can overcome polarisation. Health systems themselves, if developed as social institutions, can influence the nature of society and contribute to greater unity. Mooney raised similar concerns about policies arising from mono-cultural global perspectives and argued that, whether at the national or global level, values for health systems should be based on community preferences. He particularly highlighted the unequal distribution of benefits of neoliberal globalisation as the cause of growing health and wealth inequalities globally. There is resonance between Mooney's views on these issues and some of the contributions to the post-2015 development agenda debates. While it is unlikely that we have reached a point where the stranglehold of neo-liberal governments on key global institutions will be broken, the current debates nevertheless present an important window of opportunity to struggle for shifts in

    The authors analysed the curricula of five veterinary schools in Southeast Asia to determine how successfully they integrate the issues of global animal health and global public health into their programmes. Two schools offer a five-year programme while the remaining three offer a six-year programme. The core courses within the curricula range from 145 to 224 credit hours, in total. In general, world animal health and world public health are well integrated into the veterinary curriculum. Most curricula allocate approximately 3% of their total credit hours to subjects associated with animal and public health, but other subjects that may contain discussions on these issues range between 6% and 10%. Most veterinary schools in Southeast Asia offer a Master's programme in Veterinary Public Health, with detailed emphasis on animal and public health but focusing principally on topics of local importance. At the same time, undergraduate and post-graduate veterinary students are exposed to current issues in animal and public health through regional and international scientific meetings.

  9. Ethical issues in genetics and public health in Latin America with a focus on Argentina.

    Penchaszadeh, Victor B

    2015-07-01

    This paper reviews the health situation and developments in medical genetics and bioethics in Latin America, with a focus on Argentina. The region is the most inequitable in the world, with an average Gini Index of 52.5 and 25 % of the population living in poverty. Health expenditures are low and health systems are fragmented and privatised, with curtailed governmental responsibility and regulation. Health-care decision making is mostly in the hands of private insurance corporations and the medical-industrial complex, so that what is (or is not) covered by health plans is arbitrary and determined by the market and not by population health needs. This inequity and the lack of meaningful governmental intervention in the provision of health care, including genetic services, are at the heart of the bioethical dilemmas in Latin America. It is not surprising, therefore, that bioethics in the region has developed an approach grounded in social justice, equity and human rights as guiding principles, in contrast to the individualism espoused by Anglo-Saxon bioethics. The main ethical issues identified in genetics in Latin America are (1) inequity in access to genetic services, particularly in prenatal diagnosis, (2) genetic discrimination and (3) the lack of adherence to internationally accepted requisites of clinical validity and utility for diagnostic and predictive genetic testing. In this context, there is a risk that the impressive advances in genetics/genomics occurring in developed countries may fail to improve the public's health and deepen inequity, with the implementation of expensive genetic technologies of unproven validity.

    Background The limited integration of ethics in nutrition-related public health policies and interventions is one major concern for those who have the task of implementing them. Ethical challenges that are overlooked during the development of such interventions could raise serious ethical issues during their implementation and even after. As a result, these decision makers need technical support and ethical guidance for adaptation of interventions to local (cultural, social, economic, etc.) contexts. Aim The goal of this scoping review is to delineate and “map” the range of ethical issues in nutrition-related public health interventions, as well as the range of the various fields in which they may arise. Methods A scoping review of empirical research and conceptual literature was conducted following the framework of Arksey and O’Malley. Searches using PubMed with Medical Subject Headings (MeSH) categories and Advanced Search Builder as well as in the Global Health Library were performed. The final sample consists of 169 publications. Results The ethics of public health prevention or treatment of obesity and non-communicable diseases is the most explicitly and frequently discussed subject. In comparison, ethical issues raised by public health interventions in the fields of undernutrition, breastfeeding, vitamin/mineral supplementation and food fortification, food security, food sustainability and food safety are addressed in a lower proportion of the sample. The results illustrate the various natures, types, and scopes of existing public health nutrition-related interventions, and the various ethical issues that may be raised by these interventions, in addition to the numerous and different contexts in which they may be implemented.

    2014-01-01

    The public opinion on the energy and environmental issues has changed greatly in Japan through experiences in and along the Great East Japan Earthquake. We conducted a social survey in order to grasp public opinions for environment and energy issues in March, 2014, which obtained 2313 valid responses (response rate was 64.3%). For the energy and environmental issues, while respondents show high interests in matters related to the Fukushima accident and nuclear power generation as well as electricity prices, they show relatively low interest in every other aspect. With regard to Japan's energy policy in the future, as expectations for renewable and natural sources of energy are large, about 60% of respondents have negative attitude in restart of nuclear power. For nuclear power, as compared to the previous survey conducted in August 2008, evaluation of 'control-ability of environmental impacts' and 'the power companies' risk management ability' was greatly reduced in particular. These results suggest the importance of provoke interest in the energy issues in general, as a premise to seek an understanding of the activities of the government and power companies. Furthermore, in order for the power companies to restore trust from the public, it is important to sympathize to public's anticipations of impacts on the health and environment through uses of nuclear power in the future.

    The Relay Mirror Experiment (RME) is a research program to determine the pointing accuracy and stability levels achieved when a laser beam is reflected by the RME satellite from one ground station to another. This paper reports the results of using a video tracker augmented with a quad cell signal to improve the RME ground station tracking system performance. The video tracker controls a mirror to acquire the RME satellite, and provides a robust low bandwidth tracking loop to remove line of sight (LOS) jitter. The high-passed, high-gain quad cell signal is added to the low bandwidth, low-gain video tracker signal to increase the effective tracking loop bandwidth, and significantly improves LOS disturbance rejection. The quad cell augmented video tracking system is analyzed, and the math model for the tracker is developed. A MATLAB model is then developed from this, and performance as a function of bandwidth and disturbances is given. Improvements in performance due to the addition of the video tracker and the augmentation with the quad cell are provided. Actual satellite test results are then presented and compared with the simulated results.

  17. Analyzing Virtual Physics Simulations with Tracker

    2017-12-01

    In the physics teaching community, Tracker is well known as a user-friendly open source video analysis software, authored by Douglas Brown. With this tool, the user can trace markers indicated on a video or on stroboscopic photos and perform kinematic analyses. Tracker also includes a data modeling tool that allows one to fit some theoretical equations of motion onto experimentally obtained data. In the field of particle mechanics, Tracker has been effectively used for learning and teaching about projectile motion, "toss up" and free-fall vertical motion, and to explain the principle of mechanical energy conservation. Also, Tracker has been successfully used in rigid body mechanics to interpret the results of experiments with rolling/slipping cylinders and moving rods. In this work, I propose an original method in which Tracker is used to analyze virtual computer simulations created with a physics-based motion solver, instead of analyzing video recording or stroboscopic photos. This could be an interesting approach to study kinematics and dynamics problems in physics education, in particular when there is no or limited access to physical labs. I demonstrate the working method with a typical (but quite challenging) problem in classical mechanics: a slipping/rolling cylinder on a rough surface.

    A metric is developed to analyze the daily performance of single-axis photovoltaic (PV) trackers. The metric relies on comparing correlations between the daily time series of the PV power output and an array of simulated plane-of-array irradiances for the given day. Mathematical thresholds and a logic sequence are presented, so the daily tracking metric can be applied in an automated fashion on large-scale PV systems. The results of applying the metric are visually examined against the time series of the power output data for a large number of days and for various systems. The visual inspection results suggest that overall, the algorithm is accurate in identifying stuck or functioning trackers on clear-sky days. Visual inspection also shows that there are days that are not classified by the metric where the power output data may be sufficient to identify a stuck tracker. Based on the daily tracking metric, uptime results are calculated for 83 different inverters at 34 PV sites. The mean tracker uptime is calculated at 99% based on 2 different calculation methods. The daily tracking metric clearly has limitations, but as there is no existing metrics in the literature, it provides a valuable tool for flagging stuck trackers.

  19. Star Tracker Performance Estimate with IMU

    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.

    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...

  1. 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.

  4. Synthetic Biology between Self-Regulation and Public Discourse: Ethical Issues and the Many Roles of the Ethicist.

    Science.gov (United States)

    Arnason, Gardar

    2017-04-01

    This article discusses the roles of ethicists in the governance of synthetic biology. I am particularly concerned with the idea of self-regulation of bioscience and its relationship to public discourse about ethical issues in bioscience. I will look at the role of philosophical ethicists at different levels and loci, from the "embedded ethicist" in the laboratory or research project, to ethicists' impact on policy and public discourse. In a democratic society, the development of governance frameworks for emerging technologies, such as synthetic biology, needs to be guided by a well-informed public discourse. In the case of synthetic biology, the public discourse has to go further than merely considering technical issues of biosafety and biosecurity, or risk management, to consider more philosophical issues concerning the meaning and value of "life" between the natural and the synthetic. I argue that ethicists have moral expertise to bring to the public arena, which consists not only in guiding the debate but also in evaluating arguments and moral positions and making normative judgments. When ethicists make normative claims or moral judgments, they must be transparent about their theoretical positions and basic moral standpoints.

    The direct case for fuel economy standards on a stand alone basis dies in the textbook on the basis of first principles: the fuel tax is a better targeted instrument. In practice, the fuel economy standard, is killed by the 'rebound effect'. Vehicle users will, once they have more fuel efficient vehicles, respond to lower marginal costs by increased vehicle use. If an important part of negative externalities from transport are associated with vehicle kilometres (accidents, congestion, road wear) rather than fuel consumption, the rebound effect increases negative externalities from transport. The more direct way of addressing negative externalities from transport is to increase fuel taxes, and depending on their prior level, this is our first recommendation. But higher fuel taxes often raise political resistance. The fuel efficiency of existing cars is an important way by which people have adapted to present fuel taxes, determining their resistance to increases. A higher fuel efficiency standard is an instrument that faces little political resistance and which - over time - reduces the political resistance to increased fuel taxes. In efforts to reduce the fuel intensity of an economy, this interplay between an activity's fuel intensity, like gallons per vehicle mile, and the activity level, vehicle miles travelled or transported, nicely illustrates some important empirical questions and public policy issues: i) the first best policy proposition to reduce fuel related externalities is fuel taxes. Indeed, at the right level of fuel taxes, the externalities are zero: they are internalized. ii) the part of an economy's ability to shed fuel consumption lies in increased fuel efficiency in the individual activities, and this part can be stimulated with fuel efficiency standards. The other part, the activity level, should then be addressed with fuel tax increases. iv) We speculate that it may be difficult credibly to raise expected fuel taxes more than

    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

    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.

    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.

  12. The Educated Citizen and Global Public-Health Issues: One Model for Integration into the Undergraduate Curriculum.

    Science.gov (United States)

    Caron, Rosemary M

    2016-01-01

    The Educated Citizen Initiative proposes that an understanding of public-health issues is a core component of an educated citizenry and is essential to develop 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.

    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.

    Science.gov (United States)

    Petrini, Carlo

    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. Advocating for responsible oil and natural gas extraction policies; FracTracker as a mechanism for overcoming the barriers to scientific advocacy for academics and communities

    2013-12-01

    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

    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.)

    Full Text Available The need of all parts of the modern Ukrainian society for structural transformations determines the direction of development of the country and its territories. One of such priority vectors is the decentralization reform, efficiency of which is inextricably linked with the changes that occur in all vital for the development of society and every individual public areas: public administration, judicial system, law enforcement bodies, deregulation and development of business, banking and financial sectors, innovation and trade policies, education, medicine and other sectors of the economy and social sphere. The initiated in Ukraine transformations, including the decentralization of public power, require further legislative changes and desire of all public institutions to ensure their effective implementation through public initiative and public support. Monitoring the course of the decentralization reform in Ukraine has demonstrated little actual results of its implementation. Today an adequate legislation framework concerning the powers, resources and responsibilities has not been established yet. It is advisable to carry out a profound theoretical and practical study of the world and Ukrainian experience, develop and introduce an own science-based system of power decentralization with consideration for historical, ideological, cultural, social, economic, geographical and other features of the country, while taking into account the best practices, which can be effectively used.

    1995-01-01

    Public acceptance of sites for radioactive and other hazardous waste disposal facilities represents one of most important factors in decision making on definite sites of these facilities. The Republic of Croatia, as a newly independent state, faces the problem of public involvement in site selection of radioactive/hazardous waste disposal facility very seriously, specially having in mind that in the past, in former Yugoslavia almost all decisions had been made without participation of the public. Because of that it is very important now to gain confidence of the public and to enable its active role in decision making. Operation of the APO-Hazardous Waste Management Agency as a state agency which has been established firstly for management of radioactive waste, and later widening its competencies also to other types of hazardous wastes and relations to the public, is going to be presented in the paper. Description of some basic elements related to public participation in site selection of radioactive waste repository in Croatia will be also done

    Gaining a better understanding of the biological mechanisms underlying the individual variation observed in response to rewards and reward cues could help to identify and treat individuals more prone to disorders of impulsive control, such as addiction. Variation in response to reward cues is captured in rats undergoing autoshaping experiments where the appearance of a lever precedes food delivery. Although no response is required for food to be delivered, some rats (goal-trackers) learn to approach and avidly engage the magazine until food delivery, whereas other rats (sign-trackers) come to approach and engage avidly the lever. The impulsive and often maladaptive characteristics of the latter response are reminiscent of addictive behaviour in humans. In a previous article, we developed a computational model accounting for a set of experimental data regarding sign-trackers and goal-trackers. Here we show new simulations of the model to draw experimental predictions that could help further validate or refute the model. In particular, we apply the model to new experimental protocols such as injecting flupentixol locally into the core of the nucleus accumbens rather than systemically, and lesioning of the core of the nucleus accumbens before or after conditioning. In addition, we discuss the possibility of removing the food magazine during the inter-trial interval. The predictions from this revised model will help us better understand the role of different brain regions in the behaviours expressed by sign-trackers and goal-trackers.

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.

    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.

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

    To examine the possibilities for research into news reporting and its role in reflecting and informing public and political beliefs and action in relation to alcohol and drinking practices. Studies on media and alcohol, focusing on the role of media in relation to alcohol consumption and drinking-related practices, policies and beliefs. Most research on alcohol and media has focused on either advertising or entertainment media content, rather than on news reporting and its wider social implications. The role of news reporting could usefully be widened. We offer a framework for analysing the role of news media in relation to public debate and practice with regard to alcohol and drinking.

    2016-01-01

    Sun trackers are widely used to investigate scattering and absorption of solar radiation in the Earth's atmosphere. We present a method for optimization of the optical altazimuth sun tracker model with output radiation direction aligned with the axis of a stationary spectrometer. The method solves the problem of stability loss in tracker pointing at the Sun near the zenith. An optimal method for tracker calibration at the measurement site is proposed in the present work. A method of moving calibration is suggested for mobile applications in the presence of large temperature differences and errors in the alignment of the optical system of the tracker. - Highlights: • We present an optimal optical sun tracker model for atmospheric spectroscopy. • The problem of loss of stability of tracker pointing at the Sun has been solved. • We propose an optimal method for tracker calibration at a measurement site. • Test results demonstrate the efficiency of the proposed optimization methods.

  3. Participant priorities for future market development : IMO public consultation report : issue 1.0

    International Nuclear Information System (INIS)

    2002-01-01

    As part of the Independent Electricity Market Operator's (IMO) consultation process on market development priorities, a workshop was held in January 2002 to put forward several market design issues. The 112 delegates included market participants and other stakeholders representing consumers, environmental interest groups and the financial community. The nine main market design issues that need to be addressed over the next several years are: (1) the energy forward market, (2) the capacity reserve market, (3) location marginal pricing, (4) a capability for full assignment of physical bilateral contracts, (5) the export of operating reserve, (6) moving to real time bidding, (7) encouraging dispatchability and demand side responsiveness, (8) transmission expansion, and (9) introducing markets in ancillary services. Sections of the market rules have been deferred to after market opening, and several market development obligations have been placed on the IMO, such as recommendations on the need for location pricing and its implementation timetable. It is expected that significant resources, such as staff, will be required to ensure a smooth opening of the electricity market. It is also noted that US initiatives will affect the IMO's business environment. Prior to the workshop, the participants were asked to rank the nine potential priority issues. The rankings are included in the appendix. Results indicate that location marginal pricing ranks as the first priority, followed by energy forwards market, and then the capacity reserves market. Transmission expansion ranked sixth overall. Harmonisation with the US Northeast was also mentioned in reference to the implementation of day ahead market, location marginal pricing and the implementation of capacity reserve markets. The next step in this IMO consultation process is the development of a work-plan for managing the issues over the medium term. 2 tabs., 1 fig., 4 appendices

    The PANDA experiment will be built at the FAIR facility at Darmstadt (Germany) to perform accurate tests of the strong interaction through p-bar p and p-bar A annihilation's studies. To track charged particles, two systems consisting of a set of planar, closed-packed, self-supporting straw tube layers are under construction. The PANDA straw tubes will have also unique characteristics in term of material budget and performance. They consist of very thin mylar-aluminized cathodes which are made self-supporting by means of the operation gas-mixture over-pressure. This solution allows to reduce at maximum the weight of the mechanical support frame and hence the detector material budget. The PANDA straw tube central tracker will not only reconstruct charged particle trajectories, but also will help in low momentum (< 1 GeV) particle identification via dE/dx measurements. This is a quite new approach that PANDA tracking group has first tested with detailed Monte Carlo simulations, and then with experimental tests of detector prototypes. This paper addresses the design issues of the PANDA straw tube trackers and the performance obtained in prototype tests. (authors)

    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.

    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)

    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.

    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...

  12. ATLAS Transition Radiation Tracker - large piece

    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.

    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...

  4. [Hygiene in schools - an important issue for the public health services].

    Science.gov (United States)

    Heudorf, U; Voigt, K; Eikmann, Th; Exner, M

    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.

    The Covenant of Mayors (COM) initiative invites cities to commit themselves to reduce voluntarily the greenhouse gas emissions within their territories. This manuscript presents the COM initiative and analyzes its mechanisms. In order to better quantify the penetration of the initiative, the authors introduce suitable “participation factors”. Moreover, a study and a survey are presented concerning the COM initiative in Greece. Certain barriers are identified preventing the realization of the initiative's full potential in Greece. Results from the public survey indicate lack of proper information and communication about the COM initiative and the obligations arising from its signing towards the citizens itself. Nevertheless, once the citizens are informed properly, the public acceptance of the initiative and its commitments is considerable, to the extent that its success would influence the vote of a substantial percentage of citizens. The positive role of supporting structures is evaluated and may be demonstrated through the survey's results and discussion. Recommendations are provided for future or existing signatories based on the findings of this work. - Highlights: • Factors are defined to evaluate the penetration of the Covenant of Mayors initiative. • Barriers are identified preventing the initiative reaching its full potential in Greece. • A survey conducted in Greece shows poor dissemination of the initiative to citizens. • Significant public acceptance is observed once targets and commitments are explained to citizens. • The positive role of Supporting Structures in aiding signatories is appraised

    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.

    In this work we present a simple and low cost setup that allows obtaining the light spectra and measuring the wavelength of its features. It is based on a cheap transmission diffraction grating, an ordinary digital camera and using Tracker software to increase measuring accuracy. This equipment can easily be found in most schools. The experimental setup is easy to implement (the typical setup for a pocket spectroscope) replacing the eye with the camera. The calibration is done using a light source with a well-known spectrum. The acquired images are analyzed with Tracker (freeware software frequently used for motion studies). With this system, we have analyzed several light sources. As an example, the analysis of the spectra obtained with compact fluorescent lamp allowed to recognize the spectrum of mercury in the lamp, as expected. This spectral analysis is therefore useful in schools, among other topics, to enable the recognition of chemical elements through spectroscopy, and to alert students to the different spectra of illuminating light sources used in houses and public places.

    Full Text Available Abstract Background Wearable activity trackers offer considerable promise for helping users to adopt healthier lifestyles. This study aimed to explore users’ experience of activity trackers, including usage patterns, sharing of data to social media, perceived behaviour change (physical activity, diet and sleep, and technical issues/barriers to use. Methods A cross-sectional online survey was developed and administered to Australian adults who were current or former activity tracker users. Results were analysed descriptively, with differences between current and former users and wearable brands explored using independent samples t-tests, Mann-Whitney, and chi square tests. Results Participants included 200 current and 37 former activity tracker users (total N = 237 with a mean age of 33.1 years (SD 12.4, range 18–74 years. Fitbit (67.5% and Garmin devices (16.5% were most commonly reported. Participants typically used their trackers for sustained periods (5–7 months and most intended to continue usage. Participants reported they had improved their physical activity (51–81% more commonly than they had their diet (14–40% or sleep (11–24%, and slightly more participants reported to value the real time feedback (89% compared to the long-term monitoring (78%. Most users (70% reported they had experienced functionality issues with their devices, most commonly related to battery life and technical difficulties. Conclusions Results suggest users find activity trackers appealing and useful tools for increasing perceived physical activity levels over a sustained period.

  9. Physical inactivity as a policy problem: applying a concept from policy analysis to a public health issue.

    2013-03-07

    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.

  11. Can waste management become an issue for the public acceptance of fusion?

    International Nuclear Information System (INIS)

    Dworschak, H.; Rocco, P.

    1994-01-01

    Studies on the public perception of risks indicate that: (1) The most feared risks, together with open-quotes AIDSclose quotes and open-quotes crimeclose quotes, are those related to open-quotes nuclear accidentsclose quotes and open-quotes nuclear wasteclose quotes, which are almost as dreadful as open-quotes nuclear warclose quotes whereas, open-quotes nuclear power productionclose quotes raises less concern, almost comparable to that of other social risks. (2) Low probability, high consequence risks are those of most concern. Scarce consideration is given by the public to the likelihood of occurrence. The management strategies for fusion waste should be presented taking into account the previous statements. Sensible items are: (1) Planned waste management procedures should be describe in a well detailed fashion, indicating the aim of complying with conservative limits of environmental impact. (2) The build-up of optimistic thoughts on the complete lack of potential hazard in fusion waste as well as the opposite opinion of little or no progress at all by referring to fission waste should be avoided. (3) The hazards related to fission waste should not be over emphasized. It should be stated instead that studies on this waste have produced effective handling and segregation concepts, which are being progressively applied even to conventional waste in order to reduce risks which were not perceived before. This mature and well proven technology will be applied where pertinent to fusion waste too

    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. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

    2015-01-01

    Full Text Available In order to increase the competitiveness of the Russian scientific-technological complex in the global environment, it is planned to increase competition through State funding, spent on research and development. This will allow the focus of investment resources on the most perspective ideas and projects of the most efficient scientists, communities and organisations. The article suggests that we will witness the widening of competitive forms of funding against the simultaneous and gradual cuts in the share of financing through State contracts.One of the key criteria for evaluating the competency of team leaders and research applicants for State funding are measuring those who have «achieved high scientific results in concrete field of science», as a scientometric indicator, characterising their publication activity and citation rating.The article provides evidence showing that evaluation of individual scientists and whole scientific communities based on their publication activity indicators and impact is limited and challenges the ability for targeted funding and transparency in the selection process for executive projects.

    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.

    A conceptual framework is proposed within which the notion of risk as normally used in risk assessment (RA) could be enlarged in line with the real substance of social issues of technology policy, to help avoid RA's threatened irrelevance to social decision making. It is argued that the frequent organizational incoherence and thus the unviability of modern technology arises from 'social alienation' between the innovation-commitment phase and the implementation of the technology in society. The roles of technical elites and of particular concepts of technology in this alienation are emphasized. One of the case studies deals with 'Nuclear power - myths of scientific and organizational realism' and discusses the UK nuclear 'programme' and the Three Mile Island accident.

    Understanding the effect of wildfire smoke exposure on human health represents a unique interdisciplinary challenge to the scientific community. Population health studies indicate that wildfire smoke is a risk to human health and increases the healthcare burden of smoke-impacted areas. However, wildfire smoke composition is complex and dynamic, making characterization and modeling difficult. Furthermore, current efforts to study the effect of wildfire smoke are limited by availability of air quality measures and inconsistent air quality reporting among researchers. To help address these issues, we conducted a substantive review of wildfire smoke effects on population health, wildfire smoke exposure in occupational health, and experimental wood smoke exposure. Our goal was to evaluate the current literature on wildfire smoke and highlight important gaps in research. In particular we emphasize long-term health effects of wildfire smoke, recovery following wildfire smoke exposure, and health consequences of exposure in children. Copyright © 2017 Elsevier B.V.

  19. Local authorities and electricity: territories, actors and issues within the local public service in France

    2005-06-01

    In France, the role of local authorities in the organization of the electricity supply system is largely unknown mainly due to the size of the state-owned utility Electricite de France (EDF). Local authorities and their groupings played a major role in the electrification of the national territory and have kept important prerogatives as conceding authorities of this service of general interest. These groupings also became the tools of the soft power of local actors. The geopolitical analysis of the relationships between local municipalities and electric power stakeholders shows the diversity of actors and opinions. Stuck between market liberalization issues and decentralization to local authorities, these groupings tend to reinforce their competencies. Furthermore, decentralization goes along with a reinforcement of the political involvement in local energy policy and with conflicts on the adequate territorial scale for theses policies. (author)

    An important objective of the Commission is the provision of scientifically based recommendations that merit wide spread acceptance. In today's shrinking world, radiation protection is enhanced by '...consistency of aims and standards across a wide range of countries' (p234). This highly desirable international consistency requires the development of precise values for the primary and secondary recommendations such as the dose limits, the tissue weighting factors and the radiation weighting factors. The purpose of this paper is to examine these recommendations of the Commission in light of the rather widespread is understanding of these issues. The particular topics then are the nominal probability coefficients for stochastic effects, the dose limits, the radiation weighting factors and the tissue weighting factors particularly as they relate to the annual limits on intake

    2016-11-01

    Full Text Available Following the 9/11 attacks, a coalition of West Countries, led by the United States of America, militarily occupied two countries – Afghanistan and Iraq – in part rewriting the rules which up until then had clearly outlined the difference between a war of aggression and a war of defence. 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.

    International population mobility is an underlying factor in the emergence of public health threats and risks that must be managed globally. These risks are often related, but not limited, to transmissible pathogens. Mobile populations can link zones of disease emergence to lowprevalence or nonendemic areas through rapid or high-volume international movements, or both. Against this background of human movement, other global processes such as economics, trade, transportation, environment and climate change, as well as civil security influence the health impacts of disease emergence. Concurrently, global information systems, together with regulatory frameworks for disease surveillance and reporting, affect organizational and public awareness of events of potential public health significance. International regulations directed at disease mitigation and control have not kept pace with the growing challenges associated with the volume, speed, diversity, and disparity of modern patterns of human movement. The thesis that human population mobility is itself a major determinant of global public health is supported in this article by review of the published literature from the perspective of determinants of health (such as genetics/biology, behavior, environment, and socioeconomics), population-based disease prevalence differences, existing national and international health policies and regulations, as well as inter-regional shifts in population demographics and health outcomes. This paper highlights some of the emerging threats and risks to public health, identifies gaps in existing frameworks to manage health issues associated with migration, and suggests changes in approach to population mobility, globalization, and public health. The proposed integrated approach includes a broad spectrum of stakeholders ranging from individual health-care providers to policy makers and international organizations that are primarily involved in global health management, or are influenced

    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.

    Star trackers are opto-electronic sensors used onboard of satellites for the autonomous inertial attitude determination. During the last years, star trackers became more and more important in the field of the attitude and orbit control system (AOCS) sensors. High performance star trackers are based up today on charge coupled device (CCD) optical camera heads. The Jena-Optronik GmbH is active in the field of opto-electronic sensors like star trackers since the early 80-ties. Today, with the product family ASTRO5, ASTRO10 and ASTRO15, all marked segments like earth observation, scientific applications and geo-telecom are supplied to European and Overseas customers. A new generation of star trackers can be designed based on the APS detector technical features. The measurement performance of the current CCD based star trackers can be maintained, the star tracker functionality, reliability and robustness can be increased while the unit costs are saved.

    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.

    2014-01-01

    We report on the operation and performance of the ATLAS Semi-Conductor Tracker (SCT), which has been functioning for 3 years in the high luminosity, high radiation environment of the Large Hadron Collider at CERN. Well also report on the few im- provements of the SCT foreseen for the high energy run of the LHC. We find 99.3% of the SCT modules are operational, the noise occupancy and hit efficiency exceed the design specifications; the alignment is very close to the ideal to allow on-line track reconstruc- tion and invariant mass determination. We will report on the operation and performance of the detector including an overview of the issues encountered. We observe a significant increase in leakage currents from bulk damage due to non-ionizing radiation and make comparisons with the predictions.

  8. The Educated Citizen and Global Public-Health Issues: One Model for Integration into the Undergraduate Curriculum

    The Educated Citizen Initiative proposes that an understanding of public-health issues is a core component of an educated citizenry and is essential to develop 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.

    Scholderer, Joachim

    Introduction: European agriculture has gone through troubled times. The critical point was reached in the 1980s. Support policies had increased production far beyond market demand. Allegations of support abuse were ripe. Policy-makers responded by partially replacing input- and output-linked forms...... of producer support with others. However, radical reform was avoided. In the period 2002-2004, the level of support to producers still amounted to approximately 30% of farm receipts in the EU, and 70% in Iceland, Norway and Switzerland. In the public eye, intensified agricultural production was also labelled...... a key culprit in environmental degradation. In the 1990s (notably in the reform plans set forth in the Agenda 2000 under Commissioner Franz Fischler), the EU responded by advocating the "multifunctionality" concept of agriculture. Among the EU's trading partners, the concept quickly gained notoriety...

    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 using a 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.

    Ladino, A.G.

    1999-01-01

    Public Law 105-119 (Law) was enacted in November 1997 as part of the Defense Authorization Act of 1998 (Act). The Law specifically requires the US Department of Energy (DOE) to identify lands that are suitable for conveyance or transfer at Los Alamos National Laboratory (LANL) within 90 days after enactment of the Act. In general, suitable lands include those parcels that are not required to meet the national security missions assigned to DOE at LANL within a ten year period beginning on the date of enactment of the Act. Additional suitability criteria are addressed below and include the need to establish clear title to the land and to restore areas contaminated with hazardous wastes. This proposed change in future land ownership is intended to serve as the final settlement of DOE community assistance obligations with respect to LANL and Los Alamos County and to stimulate economic development

    1996-07-01

    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.

  14. 2009 public meetings: To inform and exchange ideas on the issues at stake

    Association du personnel

    2009-01-01

    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.

  15. Motives as predictors of the public's attitudes toward solid waste issues

    Ebreo, A.; Vining, J.

    2000-02-01

    Surveys focusing on solid-waste-related issues, conducted over a period of several years, provided data from independent samples of residents of a Midwestern, USA, community. The collection of these data yielded useful information about the relationship between residents' recycling motives and their attitudes toward solid waste management in light of several changes in the solid waste infrastructure of the community over that time. The initial survey assessed baseline beliefs and attitudes, while later surveys were conducted after the implementation of a community educational program and a curbside recycling program. The findings indicated that for recyclers and nonrecyclers, different motives predicted endorsement of solid waste programs and policies. Although a similar percentage of recyclers and nonrecyclers were in support of various proposed programs and policies, concern for the environment was found to be positively related to nonrecyclers' support of proposed programs, particularly before these programs were implemented. Prior to program implementation, motives other than environmental altruism were found to be related to recyclers' support of the programs. Additional findings support the idea that educational programs and increased accessibility to recycling opportunities affect the relationship between people's attitudes toward solid waste management and their recycling motives.

    Background and Objective: Child sexual abuse among adolescents is an often overlooked issue in pediatrics, yet it is a major cause of low self esteem and stigmatization in adolescents. The objective of this study was to determine the socioeconomic determinant and pattern of child sexual abuse among adolescent attending secondary schools in South East Nigeria. Methods: This was a cross-sectional study that was carried out among children in three secondary schools in Enugu and Ebonyi states of Nigeria. Five hundred and six adolescents who met inclusion criteria were consecutively recruited into our prospective study between June and October, 2014. Results: One hundred and ninety nine (40 %) of the respondents had been abused and the commonest form of abuse was to look at pornographic pictures, drawings, films, videotapes or magazine 93(18.4%). Fifty eight (11.5%) adolescents stated that they were abused once with age at first exposure being 7-12 years 57 (11.4%). When grouped together, family members and relatives are perpetrators of child sexual abuse. There was significant difference in sex abuse between males and females (p=0.014) while there were no significant difference for age (p=0.157) and social class (p=0.233). Conclusion: Overall prevalence and one time prevalence rates of sexual abuse among adolescents in south east Nigeria was 40% and 11.5% respectively with male perpetrators. There is no link between socioeconomic class, age and child sexual abuse among adolescents. PMID:26430412

    Full Text Available Purpose. To consider the relationship between the concepts of “medical service” and “medical care” in the work of public medical institutions, based on the analysis of normative legal documents of the modern period.Materials and methods. In the course of the research, more than 18 legal and regulatory documents that were published during the period from 1990 to 2017 were analyzed, an analysis of judicial practice and related literature sources (periodicals was carried out.Results. The analysis made it possible to distinguish the stages in the development of the organizational and legal framework for the provision of paid medical services in the Russian Federation and the dynamics of the relationship between the terms “medical care” and “medical service”. It was revealed that the concept of “medical services” appeared much later and was associated with the development of paid medical services and the need to establish legal aspects of health care. The provision of medical assistance is regulated mainly by public law, and the provision of medical services is governed by private law. The term “medical care” is broader than the “medical service” from the standpoint of the social aspect. At the same time, the concept of “medical service” can be considered more widely than medical care in cases when it is not only about measures aimed at treating the patient, but also about providing additional services to the patient in the process of receiving medical care.Conclusion. Thus, we concluded that the categories of medical care and medical services should not be identified, but also not completely different concepts, but rather enter into a partial intersection relationship. The need to distinguish between the concepts of “medical care” and “medical service” is dictated not only by the category relations or opinion of the population and the medical community, but also by the need for legal support for the process of

    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.

  19. The health-development link: travel as a public health issue.

    Rodriguez-Garcia, R

    2001-04-01

    The process of globalization has rendered societies interdependent on one another and has fostered the movement of people, goods and ideas at unprecedented speed and volume. Global travel has grown from 25 million in 1950 to 500 million in 1993, and estimations by 2010 reach 1 billion. The increased intensity and quantity of travel has resulted in greater vulnerability to the domino-type spread of old, new and re-emerging infectious diseases. Travelers and local populations are also vulnerable to death and disability due to accidents, violence and injuries, chronic diseases such as those due to substance abuse (tobacco, alcohol and others), and to undesirable behaviors such as those related to sex-tourism. This article argues that tourism, understood as any type of travel, is one of the most important sectors of the economy in many countries and, therefore, can contribute to community and national development. It also asserts that travel, as a factor in the spread of disease, lies in the realm of public health inquiry. It calls for greater collaboration between the tourism-travel industry and community, national and global leaders to promote and enforce "responsible tourism."

    The present rules of radiation protection are based on the concepts adopted fifteen years ago and now outdated, and on the ICRP 60 publication. They have become a matter of dispute among experts groups, research, and the regulatory authorities. A major role in this debate is played by new basic scientific and epidemiological findings, economic and political interests, the influence of the media, and the psychology of risk perception. For instance, also the different evaluations of natural and manmade radiation exposures contribute to the general sense of uncertainty. The article summarizes the discussion, and the development, in the past two or three years. Special attention is given to the trends which are to result in sound, feasible practices from the currently dominating assumption of the LNT/collective dose hypotheses with an interpolation to low or even very low doses. The renewed discussion sparked off by current research findings should result in a reasonable way of handling radiation so as to be able to classify a potential radiation risk in an appropriate balance between natural and manmade risks.

  1. 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.

  2. [Healthcare Provider Professional Secrecy: an Issue for Public Health Democracy somewhere between Immanence and Alienation.

    Pautier, Silvère

    2017-09-01

    For a long time considered as total and absolute, healthcare professional secrecy is today difficult to reconcile with care practices. Lots of paradoxes question its preservation in favour of general interest and public order against the protection of private interest within an individualistic normative society. Exploring this interrogation, the article's objective is to initiate an ethical discussion from a professional caregiver secrecy's historical and sociological evolution perspective. Thus, with the help of theoretical understandings, especially those by Michel Foucault, medical secrecy is considered a defense of rationality specific to populations' government. This conceptualization finds arguments through social collective norms attached to an alienating biopower at the expense of secrecy integrated as an individualistic and immanent social norm. However, beyond the well-known debate on the absolute necessity for change, evolution… the distance from the Socratic and Hippocratic principles engage people and society in real democratic decisions about Health. Also, health professionals, patients, usgers and society must consider the limits that would lead to medical confidentiality.

    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.

    The Transition Radiation Tracker (TRT) is the outermost charged particle tracking device of the ATLAS Inner Detector. The TRT has about 300,000 straws, each of which is a proportional drift tube with a diameter of 4 mm. For a precise measurement of the trajectory of a charged particle (track), the relation between the measured time of the start of the signal and the distance of closest approach between the track and the anode wire needs to be calibrated. In this note, we present the calibration of the TRT detector during the first year of 7 TeV collision data-taking.

    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.

    Ganss, C; Young, A; Lussi, A

    2011-09-01

    This paper addresses methodological issues in the field of tooth wear and erosion research including the epidemiological indices, and identifies future work that is needed to improve knowledge about tooth wear and erosion. The paper is result of the work done at the meetings of the Special Interest Group "Tooth Surface Loss and Erosion" at the 2008, 2009 and 2010 conferences of the European Association for Dental Public Health, and the Workshop "Current Erosion indices- flawed or valid" which took place in Basel in 2007. Although there is consensus about the definition and the diagnostic criteria of various forms of tooth wear, gaps in research strategies have been identified. A basic problem is that fundamental concepts of wear and erosion as an oral health problem, have not yet been sufficiently defined. To a certain extent, tooth wear is a physiological condition, and there is no consensus as to whether it can be regarded as a disease. Furthermore, the multitude of indices and flaws in existing indices, make published data difficult to interpret. Topics for the research agenda are: the initiation of a consensus process towards an internationally accepted index, and the initiation of data collection on the prevalence of various forms of wear on a population-based level. There should be an emphasis on promoting communication between basic and clinical sciences, and the area of Public Health Dentistry. Furthermore, the question of whether tooth wear is a public health problem remains open for debate.

    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

    In this article, we examine framing effects regarding unconventional oil and gas extraction using hydraulic fracturing (or fracking): an issue involving considerable controversy over potential impacts as well as terminology used to describe it. Specifically, we explore how two commonly used terms to describe this issue – fracking or shale oil or gas development – serve as issue frames and influence public opinion. Extending existing research, we suggest that these frames elicit different top-of-mind associations that reflect positive or negative connotations and resonate with people's political ideology. These associations, in turn, help explain direct and indirect framing effects on support/opposition as well as whether these effects differ by political ideology. Results of a split-ballot, national U.S. survey (n=1000) reveal that people are more supportive of the energy extraction process when it is referred to as shale oil or gas development versus fracking, and this relationship is mediated by greater perceptions of benefit versus risk. Political ideology did not moderate these effects. Further analysis suggests that these findings are partly explained by the tendency to associate fracking more with negative thoughts and impacts and shale oil or gas development more with positive thoughts and impacts. However, these associations also did not vary by political ideology. We discuss implications for communicating risk regarding energy development. -- Highlights: •How an issue is presented (“framed”) influences how people perceive it. •We applied this premise to oil/gas extraction via hydraulic fracturing (fracking). •We examined two commonly used frames: fracking and shale oil or gas development. •People viewed the former less favorably irrespective of political ideology. •We discuss implications for communicating about energy development impacts

    Full Text Available KLOE-2 at the DAΦNE Φ-factory is the main experiment of the INFN Laboratori Nazionali di Frascati (LNF and is the first high-energy experiment using the GEM technology with a cylindrical geometry, a novel idea developed at LNF. Four concentric cylindrical triple-GEM detectors compose the Inner Tracker, inserted around the interaction region and before the inner wall of the pre-existing KLOE Drift Chamber to improve the resolution on decay vertices close to the interaction point. State-of-the-art solutions have been expressly developed or tuned for this project: single-mask GEM etching, multi-layer XV patterned readout, PEEK spacer grid, GASTONE front-end board, a custom 64-channel ASIC with digital output, and the Global Interface Board for data collection, with a configurable FPGA architecture and Gigabit Ethernet. Alignment and calibration of a cylindrical GEM detector was never done before and represents one of the challenging activities of the experiment.

    The GigaTracker is an hybrid silicon pixel detector built for the NA62 experiment aiming at measuring the branching fraction of the ultra-rare kaon decay K + ! p + n ̄ n at the CERN SPS. The detector has to track particles in a beam with a flux reaching 1.3 MHz/mm 2 and provide single-hit timing with 200ps RMS resolution for a total material budget of less than 1.5 X 0 . The tracker comprises three 60.8mm 27mm stations installed in vacuum ( 10$^{-6}$ mbar) and cooled with liquid C 6 F 14 circulating through micro-channels etched inside few hundred of microns thick silicon plates. Each station is composed of a 200 m m thick silicon sensor readout by 2 x 5 cus- tom 100 m m thick ASIC, called TDCPix. Each chip contains 40 x 45 asynchronous pixels, each 300 m m x 300 m m and is instrumented with 100ps bin time-to-digital converters. In order to cope with the high rate, the TDCPix is equipped with four 3.2Gb/s serialisers sending out the data. We will describe the detector and the results from the 2014 NA62 ru...

    The CMS Silicon Strip Tracker at the LHC comprises a sensitive area of approximately 200 m 2 and 10 million readout channels. Its data acquisition system is based around a custom analogue front-end chip. Both the control and the readout of the front-end electronics are performed by off-detector VME boards in the counting room, which digitise the raw event data and perform zero-suppression and formatting. The data acquisition system uses the CMS online software framework to configure, control and monitor the hardware components and steer the data acquisition. The first data analysis is performed online within the official CMS reconstruction framework, which provides many services, such as distributed analysis, access to geometry and conditions data, and a Data Quality Monitoring tool based on the online physics reconstruction. The data acquisition monitoring of the Strip Tracker uses both the data acquisition and the reconstruction software frameworks in order to provide real-time feedback to shifters on the operational state of the detector, archiving for later analysis and possibly trigger automatic recovery actions in case of errors. Here we review the proposed architecture of the monitoring system and we describe its software components, which are already in place, the various monitoring streams available, and our experiences of operating and monitoring a large-scale system

    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...

    KLOE-2 at the DAΦNE Φ-factory is the main experiment of the INFN Laboratori Nazionali di Frascati (LNF) and is the first high-energy experiment using the GEM technology with a cylindrical geometry, a novel idea developed at LNF. Four concentric cylindrical triple-GEM detectors compose the Inner Tracker, inserted around the interaction region and before the inner wall of the pre-existing KLOE Drift Chamber to improve the resolution on decay vertices close to the interaction point. State-of-the-art solutions have been expressly developed or tuned for this project: single-mask GEM etching, multi-layer XV patterned readout, PEEK spacer grid, GASTONE front-end board, a custom 64-channel ASIC with digital output, and the Global Interface Board for data collection, with a configurable FPGA architecture and Gigabit Ethernet.

    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...

    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.

    2013-01-01

    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 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...

    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 whol...

    New visualization technologies, from ArcGIS to Google Earth, have allowed for the integration of complex, disparate data sets to produce visually rich and compelling three-dimensional models of sub-surface and surface resource distribution patterns. The rendering of these models allows the public to quickly understand complicated geospatial relationships that would otherwise take much longer to explain using traditional media. We have impacted the community through topical policy presentations at both state and city levels, adult education classes at the Denver Museum of Nature and Science (DMNS), and public lectures at DMNS. We have constructed three-dimensional models from well data and surface observations which allow policy makers to better understand the distribution of groundwater in sandstone aquifers of the Denver Basin. Our presentations to local governments in the Denver metro area have allowed resource managers to better project future ground water depletion patterns, and to encourage development of alternative sources. DMNS adult education classes on water resources, geography, and regional geology, as well as public lectures on global issues such as earthquakes, tsunamis, and resource depletion, have utilized the visualizations developed from these research models. In addition to presenting GIS models in traditional lectures, we have also made use of the immersive display capabilities of the digital "fulldome" Gates Planetarium at DMNS. The real-time Uniview visualization application installed at Gates was designed for teaching astronomy, but it can be re-purposed for displaying our model datasets in the context of the Earth's surface. The 17-meter diameter dome of the Gates Planetarium allows an audience to have an immersive experience---similar to virtual reality CAVEs employed by the oil exploration industry---that would otherwise not be available to the general public. Public lectures in the dome allow audiences of over 100 people to comprehend

    2015-05-01

    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.

  10. Studies for the Commissioning of the CERN CMS Silicon Strip Tracker

    2008-01-01

    In 2008 the Large Hadron 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...

  11. 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...

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.

    2017-01-01

    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 module needs to be determined with a precision of several micrometers. The presented alignment results are derived following a global (Millepede-II) and a local (HipPy) fit approach. The performance of the CMS tracker alignment in 2016 using cosmic-ray data and the complete set of proton-proton collision data recorded at 3.8 T magnetic field has been studied. The data-driven validation of the results are shown. The time-dependent movement of the pixel detector's large-scale structure is demonstrated.

    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.

    Blom, M R; Tuning, N

    2009-01-01

    The modules of the LHCb outer tracker have shown to suffer severe gain loss under moderate irradiation. This process is called ageing. Ageing of the modules results from contamination of the gas system by glue, araldite AY 103-1, used in their construction. In this thesis the ageing process will be shown. The schemes known to reduce, reverse, or prevent ageing have been investigated to determine their effect on the detector performance. The addition of O2 to the gas mixture lowers the detector response by an acceptable amount and does not affect the gas transport properties significantly. The ageing rate is decreased after extensive flushing and HV training could eventually repair the irradiation damage. The risks of HV training have been assessed. Furthermore, several gaseous and aquatic additions have been tested for their capability to prevent, or moderate ageing, but none showed significant improvement.

    The Front End Driver, FED, is a 9U 400mm VME64x card designed for reading out the Compact Muon Solenoid, CMS, silicon tracker signals transmitted by the APV25 analogue pipeline Application Specific Integrated Circuits. The FED receives the signals via 96 optical fibers at a total input rate of 3.4 GB/sec. The signals are digitized and processed by applying algorithms for pedestal and common mode noise subtraction. Algorithms that search for clusters of hits are used to further reduce the input rate. Only the cluster data along with trigger information of the event are transmitted to the CMS data acquisition system using the S-LINK64 protocol at a maximum rate of 400 MB/sec. All data processing algorithms on the FED are executed in large on-board Field Programmable Gate Arrays. Results on the design, performance, testing and quality control of the FED are presented and discussed.

    2017-01-01

    During the LHC shutdown in Winter 2016/17, the CMS pixel detector, the inner component of the CMS Tracker, was replaced by the Phase-1 upgrade detector. Among others improvements, the new pixel detector consists of four instead of three layers in the central barrel region (BPIX) and three instead of two disks in the endcap regions (FPIX). In this report, performance plots of pixel detector alignment results are presented, which were obtained with both cosmic-ray and pp collision data acquired at the beginning of the 2017 LHC operation. Alignment constants have been derived for each data-taking period to the level of single module positions in both the pixel and the strip detectors. The complete understanding of the alignment and biases was derived by using two algorithms, Millepede-II and HipPy. The results confirm each other.

    2017-02-01

    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.

    2008-01-01

    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 APS sensors 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

    We demonstrated the feasibility of using holographic waveguide for eye tracking. A custom-built holographic waveguide, a 20 mm x 60 mm x 3 mm flat glass substrate with integrated in- and out-couplers, was used for the prototype development. The in- and out-couplers, photopolymer films with holographic fringes, induced total internal reflection in the glass substrate. Diffractive optical elements were integrated into the in-coupler to serve as an optical collimator. The waveguide captured images of the anterior segment of the eye right in front of it and guided the images to a processing unit distant from the eye. The vector connecting the pupil center (PC) and the corneal reflex (CR) of the eye was used to compute eye position in the socket. An eye model, made of a high quality prosthetic eye, was used prototype validation. The benchtop prototype demonstrated a linear relationship between the angular eye position and the PC/CR vector over a range of 60 horizontal degrees and 30 vertical degrees at a resolution of 0.64-0.69 degrees/pixel by simple pixel count. The uncertainties of the measurements at different angular positions were within 1.2 pixels, which indicated that the prototype exhibited a high level of repeatability. These results confirmed that the holographic waveguide technology could be a feasible platform for developing a wearable eye tracker. Further development can lead to a compact, see-through eye tracker, which allows continuous monitoring of eye movement during real life tasks, and thus benefits diagnosis of oculomotor disorders.

    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.

    This study examined the effects of utilizing a wearable activity tracker in a credit-based physical activity instructional program (PAIP) for promoting physical activity (PA) in college students. Fourteen PAIP courses in a large public university were randomly assigned into intervention (k = 7; n = 101) and control (k = 7; n = 86) groups. All courses focused on a core curriculum that covers basic exercise and behavioral science contents through lectures and activity sessions. A Misfit Flash activity tracker was provided to students in the intervention group. Objective PA assessments occurred at baseline, mid-, and end-of-semester during a 15-week academic semester. The control group showed a significant reduction in moderate- and vigorous-intensity PA (MVPA) minutes from baseline to the end-of-semester (P <.05), whereas the intervention group showed no changes in MVPA minutes over time. However, the intervention group also showed increased sedentary time and decreased time spent in light-intensity PA during the intervention period. Taken together, the present study found null effects of utilizing the wearable activity tracker in promoting PA in college students suggesting that intervention of primary using the wearable activity tracker as a behavior change strategy may not be effective to increase in PA in this setting.

    In October 2016, the first French drug consumption room (DCR) opened in Paris. We propose to examine the process through which this issue has been framed as a matter of public concern, after being ignored for almost 20 years. Our analysis of the controversy on DCRs investigates how public conversations on harm reduction evolve according to the time period (from the 1990s to the present), scale of discourse (local vs. national), and involved actors (politicians, professionals, local residents, and drug users). Our methodology includes analyses of media content: we reviewed 1735 articles published between 1990 and 2017. Our theoretical approach is in line with the sociology "des épreuves" derived from pragmatic sociology and controversy analysis. This approach goes beyond interactionism by attempting to place situations back into broader sociological realities. We also pay special attention to governance, a political lens that focuses on local aspects of negotiations and on the implication of a variety of actors. While the current debate on DCRs in France draws on constraints and resources already present in the harm reduction debate of the 1980s, it also repositions itself by avoiding moral argumentation and featuring less confrontation in the professional sphere. Today, we can see that the center of this tense debate has shifted from the professional sphere to the political and residential spheres. Most often, residents advance concerns that are not directly related to drug users themselves, but that derive from their apprehension of living in a displaced and stranded neighborhood. The public conversation leaves little room for drug users, even though they are the primary stakeholders of harm reduction and play a crucial role in DCR advocacy. Our work reveals that the controversy about DCR is the product of complex interactions between different kinds of actors harm reduction professionals, political actors at the local and national levels, local residents, and

    International Nuclear Information System (INIS)

    The goal of the ACNP Public Education Program was to educate and inform the greatest number of people in the areas of radiation and health and, in turn, to gain the public's understanding of Nuclear Medicine. The related low-level waste issues also were incorporated into the program. To carry out the program's objectives and design to educate the public, the ACNP established a Speaker Bureau which consists of those members of the ACNP and the Society of Nuclear Medicine (SNM) who go through the training seminars, conducted by ACNP, and are available to speak publicly about Nuclear Medicine and related low-level waste issues. In addition, the ACNP developed the necessary audiovisual and printed materials to be used in their own right or as supplemental tools. Promotion of the Speakers Bureau and the audiovisual materials to the media and other various public forums was undertaken

    We report on a fast, easily implemented method to determine all the geometrical alignment errors of a laser tracker, to high precision. The technique requires no specialist equipment and can be performed in less than an hour. The technique is based on the determination of parameters of a geometric model of the laser tracker, using measurements of a set of fixed target locations, from multiple locations of the tracker. After fitting of the model parameters to the observed data, the model can be used to perform error correction of the raw laser tracker data or to derive correction parameters in the format of the tracker manufacturer's internal error map. In addition to determination of the model parameters, the method also determines the uncertainties and correlations associated with the parameters. We have tested the technique on a commercial laser tracker in the following way. We disabled the tracker's internal error compensation, and used a five-position, fifteen-target network to estimate all the geometric errors of the instrument. Using the error map generated from this network test, the tracker was able to pass a full performance validation test, conducted according to a recognized specification standard (ASME B89.4.19-2006). We conclude that the error correction determined from the network test is as effective as the manufacturer's own error correction methodologies

  10. The Laser Alignment System for the CMS silicon strip tracker

    Olzem, Jan

    2009-01-01

    The Laser Alignment System (LAS) of the CMS silicon strip Tracker has been designed for surveying the geometry of the large-scale Tracker support structures. It uses 40 laser beams ($\\lambda$ = 1075 nm) that induce signals on a subset of the Tracker silicon sensors. The positions in space of the laser spots on the sensors are reconstructed with a resolution of 30 $\\mu$m. From this, the LAS is capable of permanent in-time monitoring of the different Tracker components relative to each other with better than 30 $\\mu$m precision. Additionally, it can provide an absolute measurement of the Tracker mechanical structure with an accuracy better than 70 $\\mu$m, thereby supplying additional input to the track based alignment at detector startup. 31 out of the 40 LAS beams have been successfully operated during the CMS cosmic muon data taking campaign in autumn 2008. The alignment of the Tracker Endcap Discs and of the discs with respect to the Tracker Inner Barrel and Tracker Outer Barrel subdetectors was measured w...
