    Freeland, Amy L; Banerjee, Shailendra N; Dannenberg, Andrew L; Wendel, Arthur M

    2013-03-01

    We assessed changes in transit-associated walking in the United States from 2001 to 2009 and documented their importance to public health. We examined transit walk times using the National Household Travel Survey, a telephone survey administered by the US Department of Transportation to examine travel behavior in the United States. People are more likely to transit walk if they are from lower income households, are non-White, and live in large urban areas with access to rail systems. Transit walkers in large urban areas with a rail system were 72% more likely to transit walk 30 minutes or more per day than were those without a rail system. From 2001 to 2009, the estimated number of transit walkers rose from 7.5 million to 9.6 million (a 28% increase); those whose transit-associated walking time was 30 minutes or more increased from approximately 2.6 million to 3.4 million (a 31% increase). Transit walking contributes to meeting physical activity recommendations. Study results may contribute to transportation-related health impact assessment studies evaluating the impact of proposed transit systems on physical activity, potentially influencing transportation planning decisions.

    2009-01-01

    Federal gas tax and public transit agreements were signed in 2005 by the Government of Canada, the Province of Ontario, the Association of Municipalities of Ontario (AMO) and the City of Toronto in order to address long-term community sustainability and invest in municipal infrastructure. The agreement committed to providing $1.9 billion to Ontario municipalities over a 5-year period. An additional $2.4 billion has been provided for a further 4-year period from 2010 to 2014. The funds are used by communities to invest in capacity building or environmentally sustainable municipal infrastructure projects. This report identified the intermediate and ultimate outcomes of the federal gas tax fund and public transit fund as of December 2008. Outcomes were presented in the categories of community energy systems, public transit, water and wastewater, solid waste, and roads and bridges. Funding highlights and economic spin-offs for the projects were also presented, as well as summaries of ancillary social outcomes. 6 tabs., 4 figs.

    2012-01-01

    When Jeremiah Horrocks first observed it in 1639, the transit of Venus was a desirable telescopic target because of its scientific value. By the next transit of Venus in 1761, though, the enlightened public also embraced it as a popular celestial phenomenon. Its stature elevated over the centuries, the transit of Venus has been featured in music, poetry, stamps, plays, books, and art. The June 2004 transit emerged as a surprising global sensation, as suggested by the search queries it generated. Google's Zeitgeist deemed Venus Transit to be the #1 Most Popular Event in the world for that month. New priorities, technologies, and media have brought new audiences to the rare alignment. As the 2012 transit of Venus approaches, the trend continues with publicly accessible capabilities that did not exist only eight years prior. For example, sites from which historic observations have been made are plotted and readily available on Google Earth. A transit of Venus phone app in development will, if fully funded, facilitate a global effort to recreate historic expeditions by allowing smartphone users to submit their observed transit timings to a database for quantifying the Astronomical Unit. While maintaining relevance in modern scientific applications, the transit of Venus has emerged as a cultural attraction that briefly intrigues the mainstream public and inspires their active participation in the spectacle.

    2016-10-01

    Full Text Available Social media has been gaining prominence in public transit agencies in their communication strategies and daily management. This study aims to better understand recent trends in social media usage in public transit agencies, to examine which agencies use what kind of social media programs for what purposes, and how they measure their programs. A survey was conducted of the top transit agencies in the nation, and results are examined through descriptive statistical analysis, correlation analysis and regression modeling. We found that while most agencies still lack clearly-defined goals and performance metrics to guide their social media development, many are increasing their social media capacity with more structural components. Public transit service usage and the level of transit service provision are the most significant determinants of agencies’ social media programming and resource investments. In contrast, the measurement of social media usage and outcomes is more significantly related to city attributes and demographic characteristics. We anticipate an increase in the usage of social media to convey transit related stories and livability benefits, such as environmental sensitivity or safety improvements, as these programs expand. Public transit agencies’ commitment to measuring social media outcomes underscores the future research need to develop best practices for measuring the impacts and performance of social media communications and investments.

  15. Transits of Venus in Public Education and Contemporary Research

    Pasachoff, J. M.

    2011-10-01

    Transits of Venus are among the rarest predictable astronomical event that humans can enjoy, and the 2012 transit will be visible by almost all the people on Earth. It is our job as educators to bring out the thrill of being able to see the tiny dot of Venus silhouetted against the solar disk even with just a simple eye-protection filter. My Website at http://www.transitofvenus.info brings together not only historical information about the five previous transits of Venus that were observed through the 20th century--1639, 1761, 1769, 1874, and 1882--but also the scientific work carried out at the 2004 transit and at recent transits of Mercury. Based on space observations of the 1999 transit of Mercury with NASA's Transition Region and Coronal Explorer (TRACE), Glenn Schneider and I provided proof of the contemporary explanation of the black-drop effect as an amalgam of instrumental point-spread and solar limb-darkening [1]. Based on observations of the changes in the total solar irradiance during the transit, we provided an analysis of this solar-system analogue to exoplanet transits [2]. High-resolution (0.5 arcsec pixels) observations of ingress and egress with TRACE during the 2004 transit provided information about the visibility of Venus's atmosphere through its refraction of sunlight, interpreted with Venus Express observations [3]. We anticipate observing the 2012 transit with groundbased facilities of the University of Hawaii at Haleakala, and of the National Solar Observatory at Sacramento Peak, and Kitt Peak, as well as with NASA and JAXA spacecraft, including Solar Dynamics Observatory, ACRIMsat, and Hinode. The Program Group on Public Education on the Occasions of Eclipses and Transits of Commission 46 on Education and Development of the International Astronomical Union, which I chair, looks forward to participating in Education and Public Outreach efforts related to the 2012 transit.

  16. Trade liberalization and the diet transition: a public health response.

    Science.gov (United States)

    Rayner, Geof; Hawkes, Corinna; Lang, Tim; Bello, Walden

    2006-12-01

    Trade liberalization remains at the forefront of debates around globalization, particularly around the impact on agriculture and food. These debates, which often focus on how poorer countries can 'trade their way' out of poverty, pay limited attention to dietary health, especially in the light of the WHO's Global Strategy for Diet, Physical Activity and Health (2004), which warned that future health burdens will be increasingly determined by diet-related chronic diseases. This article examines the diet transition as the absent factor within debates on liberalizing trade and commerce. We describe the evolution of trade agreements, noting those relevant to food. We review the association between trade liberalization and changes in the global dietary and disease profile. We illustrate some of the complex linkages between trade liberalization and the 'diet transition', illustrated by factors such as foreign direct investment, supermarketization and cultural change. Finally, we offer three scenarios for change, suggesting the need for more effective 'food governance' and engagement by public health advocates in policy making in the food and agriculture arena.

  5. Ecological transition predictably associated with gene degeneration.

    Science.gov (United States)

    Wessinger, Carolyn A; Rausher, Mark D

    2015-02-01

    Gene degeneration or loss can significantly contribute to phenotypic diversification, but may generate genetic constraints on future evolutionary trajectories, potentially restricting phenotypic reversal. Such constraints may manifest as directional evolutionary trends when parallel phenotypic shifts consistently involve gene degeneration or loss. Here, we demonstrate that widespread parallel evolution in Penstemon from blue to red flowers predictably involves the functional inactivation and degeneration of the enzyme flavonoid 3',5'-hydroxylase (F3'5'H), an anthocyanin pathway enzyme required for the production of blue floral pigments. Other types of genetic mutations do not consistently accompany this phenotypic shift. This pattern may be driven by the relatively large mutational target size of degenerative mutations to this locus and the apparent lack of associated pleiotropic effects. The consistent degeneration of F3'5'H may provide a mechanistic explanation for the observed asymmetry in the direction of flower color evolution in Penstemon: Blue to red transitions are common, but reverse transitions have not been observed. Although phenotypic shifts in this system are likely driven by natural selection, internal constraints may generate predictable genetic outcomes and may restrict future evolutionary trajectories. © The Author 2014.

    2014-10-01

    To assess and compare the number and type of outdoor food advertisements at public transit stops within suburbs of varying levels of socioeconomic disadvantage. An observational audit tool was developed and implemented to assess the number and type of food advertisements at public transit stops within Melbourne, Victoria. A total of 20 Melbourne neighbourhoods (suburbs) from across the least and the most socioeconomically disadvantaged areas were selected. All public transit stops, including train stations and bus and tram stops with a shelter were audited.  A similar proportion of transit stops in the least and most-disadvantaged suburbs displayed food advertisements (total n=203). However, some differences in the type of advertisements across suburbs were noted with advertisements for fast food restaurants, flavoured milk and fruit juice more common in the most-disadvantaged neighbourhoods (all padvertisements for diet soft drink, tea, coffee and convenience stores more common in the least-disadvantaged neighbourhoods (all padvertising at Melbourne transit stops found 30% displayed food advertisements, with those in more disadvantaged suburbs more frequently promoting chain-brand fast food and less frequently promoting diet varieties of soft drinks. These findings may help raise awareness of unhealthy environmental exposures. © 2014 Public Health Association of Australia.

  7. Remote sensing, geographical information systems, and spatial modeling for analyzing public transit services

    Science.gov (United States)

    Wu, Changshan

    Public transit service is a promising transportation mode because of its potential to address urban sustainability. Current ridership of public transit, however, is very low in most urban regions, particularly those in the United States. This woeful transit ridership can be attributed to many factors, among which poor service quality is key. Given this, there is a need for transit planning and analysis to improve service quality. Traditionally, spatially aggregate data are utilized in transit analysis and planning. Examples include data associated with the census, zip codes, states, etc. Few studies, however, address the influences of spatially aggregate data on transit planning results. In this research, previous studies in transit planning that use spatially aggregate data are reviewed. Next, problems associated with the utilization of aggregate data, the so-called modifiable areal unit problem (MAUP), are detailed and the need for fine resolution data to support public transit planning is argued. Fine resolution data is generated using intelligent interpolation techniques with the help of remote sensing imagery. In particular, impervious surface fraction, an important socio-economic indicator, is estimated through a fully constrained linear spectral mixture model using Landsat Enhanced Thematic Mapper Plus (ETM+) data within the metropolitan area of Columbus, Ohio in the United States. Four endmembers, low albedo, high albedo, vegetation, and soil are selected to model heterogeneous urban land cover. Impervious surface fraction is estimated by analyzing low and high albedo endmembers. With the derived impervious surface fraction, three spatial interpolation methods, spatial regression, dasymetric mapping, and cokriging, are developed to interpolate detailed population density. Results suggest that cokriging applied to impervious surface is a better alternative for estimating fine resolution population density. With the derived fine resolution data, a multiple

    Objectives. We isolated physical activity attributable to transit use to examine issues of substitution between types of physical activity and potential confounding of transit-related walking with other walking. Methods. Physical activity and transit use data were collected in 2008 to 2009 from 693 Travel Assessment and Community study participants from King County, Washington, equipped with an accelerometer, a portable Global Positioning System, and a 7-day travel log. Physical activity was classified into transit- and non–transit-related walking and nonwalking time. Analyses compared physical activity by type between transit users and nonusers, between less and more frequent transit users, and between transit and nontransit days for transit users. Results. Transit users had more daily overall physical activity and more total walking than did nontransit users but did not differ on either non–transit-related walking or nonwalking physical activity. Most frequent transit users had more walking time than least frequent transit users. Higher physical activity levels for transit users were observed only on transit days, with 14.6 minutes (12.4 minutes when adjusted for demographics) of daily physical activity directly linked with transit use. Conclusions. Because transit use was directly related to higher physical activity, future research should examine whether substantive increases in transit access and use lead to more physical activity and related health improvements.

    2018-01-01

    Since public transit infrastructure affects road traffic volumes and influences transportation mode choice, which in turn impacts health, it is important to estimate the alteration of the health burden linked with transit policies. We quantified the variation in health benefits and burden between a business as usual (BAU) and a public transit (PT) scenarios in 2031 (with 8 and 19 new subway and train stations) for the greater Montreal region. Using mode choice and traffic assignment models, we predicted the transportation mode choice and traffic assignment on the road network. Subsequently, we estimated the distance travelled in each municipality by mode, the minutes spent in active transportation, as well as traffic emissions. Thereafter we estimated the health burden attributed to air pollution and road traumas and the gains associated with active transportation for both the BAU and PT scenarios. We predicted a slight decrease of overall trips and kilometers travelled by car as well as an increase of active transportation for the PT in 2031 vs the BAU. Our analysis shows that new infrastructure will reduce the overall burden of transportation by 2.5 DALYs per 100,000 persons. This decrease is caused by the reduction of road traumas occurring in the inner suburbs and central Montreal region as well as gains in active transportation in the inner suburbs. Based on the results of our study, transportation planned public transit projects for Montreal are unlikely to reduce drastically the burden of disease attributable to road vehicles and infrastructures in the Montreal region. The impact of the planned transportation infrastructures seems to be very low and localized mainly in the areas where new public transit stations are planned. Copyright © 2017 Elsevier Inc.

    2015-04-01

    Full Text Available Background: An established relationship exists between public transportation (PT use and physical activity. However, there is limited literature that examines the link between PT use and active commuting (AC behavior. This study examines this link to determine if PT users commute more by active modes. Methods: A volunteer, convenience sample of adults (n = 748 completed an online survey about AC/PT patterns, demographic, psychosocial, community and environmental factors. t-test compared differences between PT riders and non-PT riders. Binary logistic regression analyses examined the effect of multiple factors on AC and a full logistic regression model was conducted to examine AC. Results: Non-PT riders (n = 596 reported less AC than PT riders. There were several significant relationships with AC for demographic, interpersonal, worksite, community and environmental factors when considering PT use. The logistic multivariate analysis for included age, number of children and perceived distance to work as negative predictors and PT use, feelings of bad weather and lack of on-street bike lanes as a barrier to AC, perceived behavioral control and spouse AC were positive predictors. Conclusions: This study revealed the complex relationship between AC and PT use. Further research should investigate how AC and public transit use are related.

    Full Text Available The problem of dishonesty and distrust is often unclear phenomena in Eastern Europe. These are common issues discussed not only in print media and television, but also social environments as well. Corruption, so unfair advantage, lies, deceit and abuse of trust are mentioned frequently during the last decades a" er the change of system in the region, especially in Balkan Peninsula. Although dishonesty and distrust (+ corruption have existed in the previous system, however, they have been hidden phenomena or issues for which there is talk in this system. Research in terms of honesty and trust include a more areas in different sectors. International literature on the subject focuses on two fundamental topics. One of which is his faith and relationship with social capital. What do some of these concepts mean in our perception? What are the benefits and harmful effects of faith and are those connected with social equity and democratic consolidation? The search for this topic is interdisciplinary because it includes political sciences, social sciences, political, legal or sociologic-and those of anthropology. As a result this thesis will provide comparative scale impasse that creates two realities of different social complexity, from the countries that have experienced the post-socialist transition, belief in family and society that retains a holding in the operations of public institutions and may create difficulties to succeed the efforts to implement the law impartially. In conclusion: Corruption is an unreliable source, which comprises behavior and violates the trust placed on official- and public officials. It includes the use of public positions for personal benefit and it creates an ill infrastructure for fragile democracies.

    1992-01-01

    The American Lung Association (ALA), the nation's oldest voluntary health organization, is dedicated to the conquest of lung disease and the promotion of lung health. The objective of the ALA Radon Public Information Program is to reduce public exposure to elevated indoor radon levels through implementing grassroots-based radon public awareness campaigns by 22 local ALA groups. The program, which is funded by a grant from the US Environmental Protection Agency (EPA), was initiated in December 1989; the first phase will continue until May, 1991. Activities of local Lung Associations include distribution of free or reduced-cost radon kits; presenting programs in elementary and secondary schools; presenting information on TV news series and talk shows, and on radio Public Service Announcements and talk shows; presenting articles and feature stories in the print media; holding conferences, workshops, and displays at fairs and other exhibitions; distributing radon fact sheets through libraries and utility company mailings; and distributing videos through video chains and libraries. The local Lung Associations also serve as promoters for the EPA/Advertising Council Radon Public Service Announcement Campaign. We will highlight the activities of the groups in communicating radon health risks to the public; we will describe the results obtained and will attempt to evaluate the merits of the various approaches on the basis of the initial results

Public transit systems in such cities consist of a large number of nodes and lines which are represented by a complex network. A station for public transit is a bridge between the people and public transit network, based on which, the concept of input and output power for each station can be defined. The objective of this study is the application of the transit connectivity indices to the multimodal transit network in the city of Tehran. The public transit network data employed in this study is taken from Tehran Traffic Control Company, and Tehran Urban and Suburban Railway Operation Company. The methodology for measuring transit connectivity consists of three measures: Node connectivity, Line connectivity and Regional connectivity, where activity density is applied to these measures. The results of node connectivity analysis shows that most of the node connectivity in concentrated in the city center with many nodes in the center along routes going north and south. The line connectivity analysis shows that there is a concentration of highly connected lines that are near Tehran municipality region 12 and 16. Finally, we find that areas with more metro and bus facilities with respect to the other areas, have a better regional connectivity. One of these areas includes Sadeghiyeh Metro Station which is the junction of Tehran Metro Line 2 and Tehran Metro Line 5 which have a high connectivity power. Results of this study can be used to suggest some ideas on how future investments in rail and bus should be prioritized. Particularly in Transit Oriented Development (TOD and sustainble development projects, urban planners can design transit stations with high performance to access the crucial services in poor areas.

    Highlights: ► We model the unique properties of strain glass which is different from that of normal martensite. ► We describe the importance of point defects in the formation of strain glass and related properties. ► The role of point defect can be attributed to global transition temperature effect (GTTE) and local field effect (LFE). -- Abstract: The transition behavior and unique properties associated with normal martensitic transition and strain glass transition are investigated by computer simulations using the phase field method. The simulations are based on a physical model that assumes that point defects alter the thermodynamic stability of martensite and create local lattice distortion. The simulation results show that strain glass transition exhibits different properties from those found in normal martensitic transformations. These unique properties include diffuse scattering pattern, “smear” elastic modulus peak, disappearance of heat flow peak and non-ergodicity. These simulation predictions agree well with the experimental observations

    Active commuting provides routine-based regular physical activity which can reduce the risk of chronic diseases. Using public transportation involves some walking or cycling to a transit stop, transfers and a walk to the end location and users of public transportation have been found to accumulate more moderate physical activity than non-users. Understanding how public transportation characteristics are associated with active transportation is thus important from a public health perspective. This study examines the associations between objective measures of access to public transportation and self-reported active commuting. Self-reported time spent either walking or cycling commuting each day and the distance to workplace were obtained for adults aged 16 to 65 in the Danish National Health Survey 2010 (n = 28,928). Access to public transportation measures were computed by combining GIS-based road network distances from home address to public transit stops an integrating their service level. Multilevel logistic regression was used to examine the association between access to public transportation measures and active commuting. Distance to bus stop, density of bus stops, and number of transport modes were all positively associated with being an active commuter and with meeting recommendations of physical activity. No significant association was found between bus services at the nearest stop and active commuting. The results highlight the importance of including detailed measurements of access to public transit in order to identify the characteristics that facilitate the use of public transportation and active commuting.

    Immigration has been one of the most relevant phenomena characterizing Italy's social history of the past 30 years. Currently, there are almost 5 million non-Italian citizens in Italy, representing about 8.2% of the country's population. At the beginning of the 80s, a small health clinic, set-up by a no-profit Catholic organization called Caritas, was thus opened in Rome - managed by medical doctors and volunteer workers - aimed at providing the new migrants (often without any social rights) the sanitary support that was unavailable or difficult to find. In time, this health clinic progressively became an observatory of migrants' general health conditions, with a particular focus on the part of this population found in marginal social and legal conditions (without a residence permit). Data recorded in Roman Caritas Health Clinic database, belonging to patient admitted to the medical centre for the first time in 1986-1987, 2003-2004 and 2013-2014, were selected and compared. Only patients from Africa, Asia, Central and Eastern Europe and Central and Southern America were included. In addition to vital statistics, both diagnosis and prescriptions are filed according to the ICD-9.CM, 1997 in the database. Only codes 001 to 999 have been taken into consideration. The resulting sample is composed of 10741 patients. Of these, 3602 relate to 1986-1987, 4341 to 2003-2004 and 2798 to 2013-2014. The total diagnostical data processed was of 12662 (2777 in 1986-1987, 5704 in 2003-2004, 4181 in 2013-2014). Over the last 30 years the most significant variable for the public health scenario is the progressively ageing population, a variable that does not occur homogeneously. Starting from 2003-2004 an upward trend for non-communicable diseases was observed, that, as suggested by this study, have patterns and determinants varying according to ethnicity. The progressive modification of the socio-demographic profile of the migrant population determined the health transition already

    International Nuclear Information System (INIS)

    2014-11-01

    The Energy Shift Financing Agency's (SFTE) project aims to establish a broad partnership between public and private entities to stimulate the economy and deliver between euros 180 bn and euros 420 bn of investment in Europe over 10 years for the benefit of medium-sized projects (in the order of euros 1 m) that are necessary for the energy transition. It will enable EU banks to finance the energy renovation of public buildings under excellent - cheap and long-term - conditions. A feasibility study has been conducted by the AFTER association with an exemplary consortium of public and private stakeholders in France: local authorities, industry players, banks/financial institutions, NGOs, Plan Batiment Durable. Many European institutions have expressed their interest in the initiative. Now the implementation of the SFTE project requires a commitment from European and national public authorities. Such a proactive real-estate policy would significantly contribute to economic recovery, cut costs, CO_2 emissions and the external deficit and improve energy independence, and could quickly create jobs. This document is the French version of the synthesis report of the SFTE project feasibility study. Two notes are attached to the document: one about the SFTE project adaptation to the Juncker's 315 bn euros investment plan, and the other about the selection of public buildings energy retrofitting in the Juncker plan and the French-German proposals

    Full Text Available Public transit has been widely recognized as a potential way to develop low-carbon transportation. In this paper, an optimal allocation model of public transit mode proportion (MPMP has been built to achieve the low-carbon public transit. Optimal ratios of passenger traffic for rail, bus, and taxi are derived by running the model using typical data. With different values of traffic demand, construction cost, travel time, and accessibilities, MPMP can generate corresponding optimal ratios, benefiting decision impacts analysis and decision makers. Instead of considering public transit as a united system, it is separated into units in this paper. And Shanghai is used to test model validity and practicality.

    2016-03-01

    Full Text Available Public transport plays a critical role in the sustainability of urban settings. The mass mobility and quality of urban lives can be improved by establishing public transport networks that are accessible to pedestrians within a reasonable walking distance. Accessibility to public transport is characterized by the ease with which inhabitants can reach means of transportation such as buses or metros. By measuring the degree of accessibility to public transport networks using a common data format, a comparative study can be conducted between different cities or metropolitan areas with different public transit systems. The General Transit Feed Specification (GTFS by Google Developers allows this by offering a common format based on text files and sharing the data set voluntarily produced and contributed by the public transit agencies of many participating cities around the world. This paper suggests a method to assess and compare public transit accessibility in different urban areas using the GTFS feed and demographic data. To demonstrate the value of the new method, six examples of metropolitan areas and their public transit accessibility are presented and compared.

    2016-09-01

    Full Text Available With the growing development of smart cities, public transit forecasting has begun to attract significant attention. In this paper, we propose an approach for forecasting passenger boarding choices and public transit passenger flow. Our prediction model is based on mining common user behaviors for semantic trajectories and enriching features using knowledge from geographic and weather data. All the experimental data comes from the Ridge Nantong Limited bus company and Alibaba platform which is also open to the public. We evaluate our approach using various data sources, including point of interest (POI, weather condition, and public bus information in Guangzhou to demonstrate its effectiveness. Experimental results show that our proposal performs better than baselines in the prediction of passenger boarding choices and public transit passenger flow.

  13. Changes in Service and Associated Ridership Impacts near a New Light Rail Transit Line

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Los Angeles (LA, for many years a city with limited rail transit, is substantially expanding its public transit system. This paradigm change in transportation policy and investment creates new requirements for monitoring. One area needing evaluation is whether new, high quality transit options, such as light rail, near existing transit services increase sustainable transportation mode shares and reduce car travel. Few studies have explored light rail’s role as a catalyst to increase overall transit use and achieve sustainability goals within an auto-oriented city like LA. Metro’s data show that trips taken on its bus and rail system dropped overall by 10.5% between 2009 and 2016, but its rail ridership grew 21% during the same period due to the debut of the Gold Line and Expo Line extensions. We analyze changes to bus service and associated ridership impacts that resulted from the opening of these two LRT lines in LA. The immediate effect of the city’s bus service changes along the Gold Line light rail extension appear to be associated with a net “bus plus rail” ridership decline in that corridor. In contrast, the Expo Line corridor experienced an initial increase in ridership during the two years immediately after its opening, possibly because the bus service was not reduced by the same magnitude as along the Gold Line extension. Our findings indicate that changes in bus service made to coincide with the introduction of new light rail transit (LRT can negatively affect the overall transit ridership in the corridor. Planners and policy makers should closely monitor changes in bus service and ridership associated with new rail transit to ensure investments results in an overall net increase in more sustainable travel.

    2014-01-01

    The financing of ecological transition is a key issue which conditions the nature of the transition and its ecological efficiency, the acceptability of measures with respect to requirements in terms of social justice, and the sustainability of undertaken actions. This publication is an answer to a public consultation launched by the French government with the publication of a White Paper on these issues. The authors first analyse, discuss and criticise the content of the White Paper. For them, it reduces the approach to a normative one, is based on a decoupling between economic growth and use of resources, propagates a technical-scientific illusion, often indicates selective and incomplete data, and addresses the energy issue through a supply-based approach. In the next part, the authors discuss how transition financing is addressed in the White Paper. In the third part, proposals are made according to three main principles: ecological transition is a social, political, and cultural process which must be supported, financed and implemented at all territorial levels; transition can be financed only if it comes with a strict legal framework which will define what is possible and what is not any longer; financing must be conditioned to results in terms of sobriety and of ecological and social efficiency, including the creation, qualification and sustainability of jobs. A set of programmes is also presented with associated measures on energy efficiency and sobriety, on a fair use of common good, on a re-localisation of activities, and a support of international initiatives. Some proposals are also made regarding financing tools

    2016-12-01

    Full Text Available The article considers the main directions of the implementation of the current transportation and transit projects on the basis of the institution of public-private partnership in Russia. This work is a continuation of the study of the theory and practice of the application of public-private partnership in the investment projects aimed at the development and realization of the transportation and transit potential of the country. On the methodological basis of evolutionary and institutional economics, historical approach, system-oriented analysis and the theory of firms, the main current projects for the development of Russian transportation and transit system using public-private partnership are considered. They are the construction of a high-speed line of Moscow — Kazan with subsequent extension to the Chinese border; functioning of the transport and logistics in the Chelyabinsk region; infrastructure of transit cargo by Northern Sea Route; participation of foreign investors in the development of Russian seaports and sea gates. It is shown that the competitive advantage of transit traffic by a particular route requires more traversing speed of cargo with a minimum of stops, handling and overloads in the way. Revenue from transportation and transit potential implementation can be comparable to the size of the resource rent in the case of the development in Russia of the production and transit sector of the economy, and not only of a transit one . In this regard, the emphasis is placed on the determination of the possibility and necessity of organizational changes associated with the development of a large public-private transportation company, able to compete with global sea container services of the route of Asia — Europe.

    2007-06-01

    Full Text Available Since transportation is one of the most complicated and the basic problem of urban life in developing countries at the present time and in various dimensions, so it is necessary to view it more scientifically-practically. Reducing travelling time is one way to reduce its cost. In public transportation system, it is important to determine proper travelling costs. There are various methods to determine the distances between stations. One of these methods used in England is based on logical and calculative relations in mathematics. In this paper, in addition to studying this method some changes have been made in order to reduce and modify required variables for calculation of those relations. A numerical example is designed to demonstrate the effectiveness of the method and thus developed to optimize the public transportation stop location problem. The sensitivity of the total travel time, access, speed and the effect of the parameters on the optimum stop location are analyzed and discussed.

    For a chaotic cavity with two identical leads each supporting N channels, we compute analytically, for large N, the full distribution of the conductance and the shot noise power and show that in both cases there is a central Gaussian region flanked on both sides by non-Gaussian tails. The distribution is weakly singular at the junction of Gaussian and non-Gaussian regimes, a direct consequence of two phase transitions in an associated Coulomb gas problem

The study team was tasked with developing a process and a supporting methodology for estimating the benefits accruing to the State from the operation of state supported public transit services. The team was also tasked with developing forecasts of the future demands for these State supported transit services at five year intervals through the year 2020, broken down where possible to the local transit system level. Separate ridership benefits and forecasts were also requested for the State's urban and rural transit operations. Tennessee's public transit systems are subsidized to a degree by taxpayers. It is therefore in the public interest that assessments of the benefits of such systems be carried out at intervals, to determine how they are contributing to the well-being of the state's population. For some population groups within the State of Tennessee these transit services have become essential as a means of gaining access to workplaces and job training centers, to educational and health care facilities, as well as to shops, social functions and recreational sites.

    The purpose of this study was to explore the associations of immigration transition to cardiovascular symptoms among 4 major racial/ethnic groups of 1054 midlife women in the United States. This was a secondary analysis of the data from 2 large national survey studies. The instruments included questions on background characteristics and immigration transition and the Cardiovascular Symptom Index for Midlife Women. The data were analyzed using inferential statistics including hierarchical multiple regressions. Immigrants reported fewer numbers (t = 5.268, P < .01) and lower severity scores (t = 5.493, P < .01) of cardiovascular symptoms compared with nonimmigrants. Self-reported racial/ethnic identify was a significant factor influencing cardiovascular symptoms (P < .01).

    2014-05-01

    Medications for the treatment of substance use disorders (SUDs) are not widely available in publicly funded SUD treatment programs. Few studies have drawn on longitudinal data to examine the organizational characteristics associated with programs transitioning from not delivering any pharmacotherapy to adopting at least one SUD medication. Using two waves of panel longitudinal data collected over a 5-year period, we measured the transition to medication adoption in a cohort of 190 publicly funded treatment organizations that offered no SUD medications at baseline. Independent variables included organizational characteristics, medical resources, funding, treatment culture, and detailing activities by pharmaceutical companies. Of 190 programs not offering SUD pharmacotherapy at baseline, 22.6% transitioned to offering at least one SUD medication at follow-up approximately 5 years later. Multivariate logistic regression results indicated that the employment of at least one physician at baseline, having a greater proportion of Medicaid clients, and pharmaceutical detailing were positively associated with medication adoption. Adoption of pharmacotherapy was more likely in programs that had greater medical resources, Medicaid funding, and contact with pharmaceutical companies. Given the potential expansion of Medicaid under the Affordable Care Act, patients served by publicly funded programs may gain greater access to such treatments, but research is needed to document health reform's impact on this sector of the treatment system.

    2001-01-01

    The Annual Canadian Urban Transit Association Conference attracted speakers from both Canada and the United States. The topics discussed during the 17 sessions fell in the broad categories of smart growth and urban transit, innovation and new ideas in the transit industry, urban transportation and climate change, the future of transit and the environment, as well as active transportation and its impact on human health. It is felt that public transit should represent the primary solution to urban mobility, with the aim of achieving sustainable transportation. Urban transit and the various means by which it can have an impact on the reduction of greenhouse gases emissions and global climate change were discussed in great depth. Community growth has spurred the demand for additional transportation, and presents challenges particular to each community. Discussions also focused on the resulting air quality and pollution problems along with some proposed solutions. Clean fuels, such as compressed natural gas, propane and methanol were also touched upon, as were emerging technologies in the fields of vehicle and new propulsion technologies. The impact of public transit on public health, from the point of view of air quality, climate change and safety was discussed. A total of 35 papers were presented at this conference, of which 9 were processed separately for inclusion in the database. tabs., figs

  6. Scale-invariant transition probabilities in free word association trajectories

    2009-09-01

    Full Text Available Free-word association has been used as a vehicle to understand the organization of human thoughts. The original studies relied mainly on qualitative assertions, yielding the widely intuitive notion that trajectories of word associations are structured, yet considerably more random than organized linguistic text. Here we set to determine a precise characterization of this space, generating a large number of word association trajectories in a web implemented game. We embedded the trajectories in the graph of word co-occurrences from a linguistic corpus. To constrain possible transport models we measured the memory loss and the cycling probability. These two measures could not be reconciled by a bounded diffusive model since the cycling probability was very high (16 % of order-2 cycles implying a majority of short-range associations whereas the memory loss was very rapid (converging to the asymptotic value in ∼ 7 steps which, in turn, forced a high fraction of long-range associations. We show that memory loss and cycling probabilities of free word association trajectories can be simultaneously accounted by a model in which transitions are determined by a scale invariant probability distribution.

    Full Text Available The development of public transit systems that are accessible and safe for everyone, including people with special needs, is an objective that is justified from the civic and economic points of view. Unfortunately, public transit services are conceived for people who do not have reduced physical or cognitive abilities. In this paper, we present an intelligent public transit system by highway with the goal of facilitating access and improving the safety of public transit for persons with special needs. The system is deployed using components that are commonly available in transport infrastructure, e.g., sensors, mobile communications systems, and positioning systems. In addition, the system can operate in non-urban transport contexts, e.g., isolated rural areas, where the availability of basic infrastructure, such as electricity and communications infrastructures, is not always guaranteed. To construct the system, the principles and techniques of Ubiquitous Computing and Ambient Intelligence have been employed. To illustrate the utility of the system, two cases of services rendered by the system are described: the first case involves a surveillance system to guarantee accessibility at bus stops; the second case involves a route assistant for blind people.

  9. Managing the Accessibility on Mass Public Transit: the Case of Hong Kong

    Directory of Open Access Journals (Sweden)

    Full Text Available Public transit services (PTS improve mobility and accessibility, and reduce car dependence. It is ideal if PTS are financially sustainable, with affordable fares and expedient quality. The success of PTS on accessibility improvement can be reflected by their level of patronage: do travelers choose to use them in lieu of their private cars? PTS in Hong Kong are renowned for their quality and profitability, superbly addressing the accessibility need for the city; they carry over 90% of the 11 million daily trips. A comparison of the per capita train-car and bus-vehicle kilometer run of PTS in Hong Kong with those in London and Singapore, however, suggests that it is not purely the supply that affects the use or accessibility of PTS in Hong Kong. By tracing and analyzing the development of PTS in Hong Kong over the past two decades, we found evidence that the high level of accessibility on mass public transit in the territory can be attributed to the land use policy of developing compact, high-density township, accompanying transport policies of granting high priority to the development of mass transit facilities and providing ways to ensure the financial viability of privately operated PTS, especially the innovative approach of integrating the development of public transport facility and property so as to exploit their synergy. In this paper, we study and highlight elements that contribute to the development of high accessibility on mass public transit in Hong Kong.

    Railway has emerged as a fast, convenient, safe, clean, and low-cost alternative to air and road transportation. Many countries have invested in rail transportation. In America, Europe and Asia, large investments are planned for rail transportation. This is because congestion problems can be reduced with the introduction of rail transportation. Rail transportation involves several components which are important to ensure the smooth and safe delivery of services such as locomotives, rail stations and railway tracks. Rail transit stations are places where trains stop to pick-up and drop-off passengers. Stations are vital for many to enable them to engage in work and social commitments. This paper focuses only on the rail transit station as it is one of the important components in rail transportation. It is also considered as a key public meeting place and space for interactions in a community. The role of rail transit station and the requirements of a good rail transit station are also described in this paper. Steps in selecting the location of rail transit station include the function and facilities in rail transit station are discussed with reference to best practices and handbooks. Selection of the appropriate rail transit station locations may help users indirectly. In addition, this paper will also elucidate on the design considerations for an efficient and effective rail transit station. Design selections for the rail transit station must be balanced between aesthetic value and functional efficiency. The right design selection may help conserve energy, assure and facilitate consumers even thought a rail transit station plays a smaller role in attracting consumers compared to a shopping complex or a residential building. This will contribute towards better and greener building for a green transportation facility. Thus, with this paper it is expected to assist the relevant authority to identify important elements in the selection and determination of suitable

    Full Text Available This study proposed a two-dimensional index system which is concerned essentially with urban travel based on travel modes and user satisfaction. First, the public transit was taken as an example to describe the index system establishing process. In consideration of convenience, rapid, reliability, comfort, and safety, a bus service evaluation index system was established. The indicators include the N-minute coverage of bus stops, average travel speed, and fluctuation of travel time between stops and bus load factor which could intuitively describe the characteristics of public transport selected to calculate bus travel indexes. Then, combined with the basic indicators, the calculation models of Convenience Index (CI, Rapid Index (RI, Reliability Index (RBI, and Comfort Index (CTI were established based on the multisource data of public transit including the real-time bus GPS data and passenger IC card data. Finally, a case study of Beijing bus operation evaluation and analysis was conducted by taking real bus operation data including GPS data and passenger transaction recorder (IC card data. The results showed that the operation condition of the public transit was well reflected and scientifically classified by the bus travel index models.

    This paper mainly studies the time optimization of feeder connection between rail transit and conventional bus in a shopping center. In order to achieve the goal of connecting rail transportation effectively and optimizing the convergence between the two transportations, the things had to be done are optimizing the departure intervals, shorting the passenger transfer time and improving the service level of public transit. Based on the goal that has the minimum of total waiting time of passengers and the number of start of classes, establish the optimizing model of bus connecting of departure time. This model has some constrains such as transfer time, load factor, and the convergence of public transportation grid spacing. It solves the problems by using genetic algorithms.

  14. Average opportunity-based accessibility of public transit systems to grocery stores in small urban areas

    2015-12-01

    Full Text Available This research studies the accessibility of grocery stores to university students using the public transportation system, drawing from a case study of Fargo, North Dakota. Taking into consideration the combined travel time components of walking, riding, and waiting, this study measures two types of accessibilities: accessibility to reach a particular place and accessibility to reach the bus stop to ride the public transit system. These two accessibilities are interdependent and cannot perform without each other. A new method to calculate the average accessibility measure for the transit routes is proposed. A step-wise case study analysis indicates that one route provides accessibility to a grocery store in eight minutes. This also suggests that the North Dakota State University area has moderate accessibility to grocery stores.

    Active commuters have lower risk of chronic disease. Understanding which of the, to some extent, modifiable characteristics of public transportation that facilitate its use is thus important in a public health perspective. The aim of the study was to examine the association between individual public transportation accessibility and self-reported active commuting, and whether the associations varied with commute distance, age, and gender. Twenty-eight thousand nine hundred twenty-eight commuters in The Capital Region of Denmark reported self-reported time spent either walking or cycling to work or study each day and the distance to work or study. Data were obtained from the Danish National Health Survey collected in February to April 2010. Individual accessibility by public transportation was calculated using a multi-modal network in a GIS. Multilevel logistic regression was used to analyze the association between accessibility, expressed as access area, and being an active commuter. Public transport accessibility area based on all stops within walking and cycling distance was positively associated with being an active commuter. Distance to work, age, and gender modified the associations. Residing within 10 km commute distance and in areas of high accessibility was associated with being an active commuter and meeting the recommendations of physical activity. For the respondents above 29 years, individual public transportation accessibility was positively associated with being an active commuter. Women having high accessibility had significantly higher odds of being an active commuter compared to having a low accessibility. For men, the associations were insignificant. This study extends the knowledge about the driving forces of using public transportation for commuting by examining the individual public transportation accessibility. Findings suggest that transportation accessibility supports active commuting and planning of improved public transit accessibility

  16. Punishment in public goods games leads to meta-stable phase transitions and hysteresis

    Hintze, Arend; Adami, Christoph

    2015-07-01

    The evolution of cooperation has been a perennial problem in evolutionary biology because cooperation can be undermined by selfish cheaters who gain an advantage in the short run, while compromising the long-term viability of the population. Evolutionary game theory has shown that under certain conditions, cooperation nonetheless evolves stably, for example if players have the opportunity to punish cheaters that benefit from a public good yet refuse to pay into the common pool. However, punishment has remained enigmatic because it is costly and difficult to maintain. On the other hand, cooperation emerges naturally in the public goods game if the synergy of the public good (the factor multiplying the public good investment) is sufficiently high. In terms of this synergy parameter, the transition from defection to cooperation can be viewed as a phase transition with the synergy as the critical parameter. We show here that punishment reduces the critical value at which cooperation occurs, but also creates the possibility of meta-stable phase transitions, where populations can ‘tunnel’ into the cooperating phase below the critical value. At the same time, cooperating populations are unstable even above the critical value, because a group of defectors that are large enough can ‘nucleate’ such a transition. We study the mean-field theoretical predictions via agent-based simulations of finite populations using an evolutionary approach where the decisions to cooperate or to punish are encoded genetically in terms of evolvable probabilities. We recover the theoretical predictions and demonstrate that the population shows hysteresis, as expected in systems that exhibit super-heating and super-cooling. We conclude that punishment can stabilize populations of cooperators below the critical point, but it is a two-edged sword: it can also stabilize defectors above the critical point.

  17. Spatial-Temporal Similarity Correlation between Public Transit Passengers Using Smart Card Data

    2017-01-01

    Full Text Available The increasing availability of public transit smart card data has enabled several studies to focus on identifying passengers with similar spatial and/or temporal trip characteristics. However, this paper goes one step further by investigating the relationship between passengers’ spatial and temporal characteristics. For the first time, this paper investigates the correlation of the spatial similarity with the temporal similarity between public transit passengers by developing spatial similarity and temporal similarity measures for the public transit network with a novel passenger-based perspective. The perspective considers the passengers as agents who can make multiple trips in the network. The spatial similarity measure takes into account direction as well as the distance between the trips of the passengers. The temporal similarity measure considers both the boarding and alighting time in a continuous linear space. The spatial-temporal similarity correlation between passengers is analysed using histograms, Pearson correlation coefficients, and hexagonal binning. Also, relations between the spatial and temporal similarity values with the trip time and length are examined. The proposed methodology is implemented for four-day smart card data including 80,000 passengers in Brisbane, Australia. The results show a nonlinear spatial-temporal similarity correlation among the passengers.

  18. SPP Toolbox: Supporting Sustainable Public Procurement in the Context of Socio-Technical Transitions

    Directory of Open Access Journals (Sweden)

    Paula Cayolla Trindade

    2017-12-01

    Full Text Available Public procurement can shape production and consumption trends and represents a stimulus for both innovation and diversification in products and services, through a direct increase in demand. In recent years, the interest in demand-side policies has grown and several approaches have emerged, such as Green Public Procurement (GPP, Sustainable Public Procurement (SPP and Public Procurement of Innovation (PPI, representing strategic goals to be achieved through public procurement. In this context, there is a need to guide and support public organizations in the uptake of GPP, SPP and PPI practices. To respond to the challenges raised by the operationalization of such strategies, this paper proposes a new tool—the SPP Toolbox—for guiding public organizations as they re-think the procurement process, raising their ambitions and broadening their vision, thus changing the organizational approach towards culture, strategies, structures and practices. This toolbox integrates insights from GPP, SPP and PPI objectives and practices, in the context of the emergence of socio-technical transitions. The toolbox coherently links GPP, SPP and PPI, allowing flexibility in terms of goals, yet promoting an increasing complexity of institutionalized practices and skills—from GPP to SPP and then from SPP to PPI, organized in a framework fully integrated into the organizational strategy.

    2008-01-01

    Potts networks, in certain conditions, hop spontaneously from one discrete attractor state to another, a process we have called latching dynamics. When continuing indefinitely, latching can serve as a model of infinite recursion, which is nontrivial if the matrix of transition probabilities presents a structure, i.e. a rudimentary grammar. We show here, with computer simulations, that latching transitions cluster in a number of distinct classes: effectively random transitions between weakly correlated attractors; structured, history-dependent transitions between attractors with intermediate correlations; and oscillations between pairs of closely overlapping attractors. Each type can be described by a reduced set of equations of motion, which, once numerically integrated, matches simulations results. We propose that the analysis of such equations may offer clues on how to embed meaningful grammatical structures into more realistic models of specific recursive processes

    Collins, Patricia A; Agarwal, Ajay

    2015-01-01

    Public transit ridership offers valuable opportunities for modest amounts of daily physical activity (PA). Transit is a more feasible option for most Canadian commuters who live too far from work to walk or cycle, yet public transit usage in midsized Canadian cities has historically remained low due to inefficient transit service. The objectives of this longitudinal study were threefold: to assess whether the introduction of express transit service in the low-density city of Kingston, Ontario, has translated to greater transit use among a targeted employee group; to document the characteristics of those employees that have shifted to transit; and to examine the PA levels of employees using transit compared to other commute modes. An online survey was administered in October 2013 and October 2014 to all non-student employees at Queen's University. 1356 employees completed the survey in 2013, and 1123 in 2014; 656 of these employees completed the survey both years, constituting our longitudinal sample. Year-round transit ridership increased from 5.5% in 2013 to 8.5% in 2014 (p transit had fewer household-level opportunities to drive to work and more positive attitudes toward transit. Transit commuters accrued an average of 80 minutes/week of commute-related PA, and 50 minutes/week more total PA than those that commuted entirely passively. Kingston Transit's express service has stimulated an increase in transit ridership among one of their target employers, Queen's University. The findings from this study suggest that shifting to transit from entirely passive commuting can generate higher overall PA levels.

    Full Text Available According to new growth theories, public governance is an important determinant for sustained economic growth. This study examines the impact of six public governance indicators, including voice and accountability, political stability and the absence of violence/terrorism, government effectiveness, regulatory quality, rule of law and control of corruption, on the economic growth in the transitional economies of the European Union during the 2002-2013 period. The results show that all governance indicators except regulatory quality had a statistically significant positive impact on economic growth. Our findings also indicate that control of corruption and rule of law had the largest impact on economic growth, while political stability had the lowest impact.

    The purpose of this study was to investigate whether transitional vertebrae contribute to the development of sacroiliac joint dysfunction. The prevalence of transitional vertebrae in patients with lumbar pain was determined during this process, and the prevalence of sacroiliac dysfunction was compared between patients with low back pain and healthy volunteers. 700 subjects, 500 with low back pain and 200 healthy volunteers were included in this study. Five tests were applied to all participants to determine sacroiliac joint dysfunction. Positivity in three tests was regarded as dysfunction. Lateral lumbosacral and Ferguson angle X-rays were taken from the group with low back pain. The patient was evaluated a specialist radiologist in terms of presence or absence of transitional vertebrae, and if identified, what type. Transitional vertebrae were determined in 26% (n = 130) of the patients with low back pain. Type 1a was determined in 20%, type 1b in 10%, type 2a in 26.9%, type 2b in 30.8%, type 3a in 0.8%, type 3b in 4.6% and type 4 in 6.9%. The prevalence of sacroiliac joint dysfunction in the low back pain group (15.4%) and the prevalence of sacroiliac joint dysfunction in cases of transitional vertebra (28.5%) were significantly higher compared to the control groups (p Sacroiliac joint dysfunction must be considered when investigating the etiology of low back pain. Particular sensitivity must be exhibited on this subject in patients with transitional vertebrae.

  6. The Impact of Carsharing on Public Transit and Non-Motorized Travel: An Exploration of North American Carsharing Survey Data

    2011-11-01

    Full Text Available By July 2011, North American carsharing had grown to an industry of nearly 640,000 members since its inception on the continent more than 15 years ago. Carsharing engenders changes in member travel patterns both towards and away from public transit and non-motorized modes. This study, which builds on the work of two previous studies, evaluates this shift in travel based on a 6281 respondent survey completed in late-2008 by members of major North American carsharing organizations. Across the entire sample, the results showed an overall decline in public transit use that was statistically significant, as 589 carsharing members reduced rail use and 828 reduced bus use, while 494 increased rail use and 732 increased bus use. Thus for every five members that use rail less, four members use rail more, and for every 10 members that ride a bus less, almost nine members ride the bus more. The people increasing and decreasing their transit use are fundamentally different in terms of how carsharing impacts their travel environment. This reduction, however, is also not uniform across all organizations; it is primarily driven by a minority (three of eleven of participating organizations. At the same time, members exhibited a statistically significant increase in travel by walking, bicycling, and carpooling. Across the sample, 756 members increased walking versus a 568 decrease, 628 increased bicycling versus a 235 decrease, and 289 increased carpooling versus a decrease of 99  study participants. The authors found that 970 members reduced their auto commuting to work, while 234 increased it. Interestingly, when these shifts are combined across modes, more people increased their overall public transit and non-motorized modal use after joining carsharing than decreased it. Data collected on the commute distance of respondents found that carsharing members tend to have shorter commutes than most people living in the same zip code. The analysis also evaluates

    Winichagoon, Pattanee

    2015-05-01

    This article reviews the maternal and child nutrition situation in Asia in transition and its public health implications. Countries in Asia are facing a double burden of malnutrition. Accessibility to high energy, less nutrient-dense foods or processed foods affects current dietary patterns, whereas industrialization is leading to more sedentary lifestyles both in rural and urban areas. Stunting and wasting among young children persist but have declined in severity, whereas overweight and obesity have risen rapidly. Growth faltering in height during the first 2 years of life has affected muscle mass accretion, but rapid weight gain after 2 years of age has led to more fat accretion, imposing risks of childhood obesity and consequent metabolic disorders. The number of women entering pregnancy with low BMI has decreased, but increasing BMI is noticeable. Prepregnancy BMI and gestational weight gain are important determinants of maternal nutrition during pregnancy, the risk of gestational diabetes and postpartum weight retention, as well as obesity and diet-related noncommunicable diseases in later adulthood. Asia in transition is faced with persistent undernutrition and increasing trends of obesity and metabolic disorders among children and women. The first 1000 days from conception is a critical period, but it is also a window of opportunity for preventing double burden of malnutrition in Asian countries characterized by a nutrition transition.

  8. Performance measurement of the gas tax and public transit funds : final report

    International Nuclear Information System (INIS)

    2007-01-01

    Federal funding for the gas tax fund and public transit fund are provided through Infrastructure Canada for municipal infrastructure across Canada in a broad range of municipal service projects. In order to identify appropriate outcomes that would meet reporting requirements for the gas tax fund and public transit fund, this report outlined a performance measurement approach that would allow for the reporting of projects under both funds and provide a structured methodology for multiple year analysis of benefits. The report discussed the performance measures process review and outcomes approach logic model. It also provided an outline of information sourcing strategies including an overview of the project types and expenditures; information sourcing strategy; typical municipal information sources by project type; performance measurement framework assumptions and limitations; and modeling of outcomes from outputs. Conclusions and recommendations were also offered. It was concluded that based on a comprehensive review of ancillary benefits and outcomes of various historic funding programs, there are 3 foundational outcomes that should be considered to assess all initial program outcomes. These include cleaner air, cleaner water and reduced greenhouse gas emissions. tabs., figs

  9. Data-Driven Transition: Joint Reporting of Subscription Expenditure and Publication Costs

    2018-04-01

    Full Text Available The transition process from the subscription model to the open access model in the world of scholarly publishing brings a variety of challenges to libraries. Within this evolving landscape, the present article takes a focus on budget control for both subscription and publication expenditure with the opportunity to enable the shift from one to the other. To reach informed decisions with a solid base of data to be used in negotiations with publishers, the diverse already-existing systems for managing publications costs and for managing journal subscriptions have to be adapted to allow comprehensive reporting on publication expenditure and subscription expenditure. In the case presented here, two separate systems are described and the establishment of joint reporting covering both these systems is introduced. Some of the results of joint reporting are presented as an example of how such a comprehensive monitoring can support management decisions and negotiations. On a larger scale, the establishment of the National Open Access Monitor in Germany is introduced, bringing together a diverse range of data from several already-existing systems, including, among others, holdings information, usage data, and data on publication fees. This system will enable libraries to access all relevant data with a single user interface.

    Genomic maps of local ancestry identify ancestry transitions - points on a chromosome where recent recombination events in admixed individuals have joined two different ancestral haplotypes. These events bring together alleles that evolved within separate continential populations, providing a unique opportunity to evaluate the joint effect of these alleles on health outcomes. In this work, we evaluate the impact of genetic variants in the context of nearby local ancestry transitions within a sample of nearly 10,000 adults of African ancestry with traits derived from electronic health records. Genetic data was located using the Metabochip, and used to derive local ancestry. We develop a model that captures the effect of both single variants and local ancestry, and use it to identify examples where local ancestry transitions significantly interact with nearby variants to influence metabolic traits. In our most compelling example, we find that the minor allele of rs16890640 occuring on a European background with a downstream local ancestry transition to African ancestry results in significantly lower mean corpuscular hemoglobin and volume. This finding represents a new way of discovering genetic interactions, and is supported by molecular data that suggest changes to local ancestry may impact local chromatin looping.

  14. French gas industry in transition: breach in the public service model

    International Nuclear Information System (INIS)

    Finon, D.

    2001-08-01

    France is generally viewed as the European country that most vigorously resists the pressure to liberalize its national gas markets. The moderate reform which has resulted from the transcription of the European gas directive was voted in 2002 after much delay. The main reason is the robustness of the French public service-model which has shaped the gas industry organisation in the same way as most of the network industries. To explain the institutional stability of the French gas industry, this document analyses its institutional trajectory shaped by the public service model and its strong institutional path dependency, marked by the resistance to change. The central hypothesis of the analysis is that, as long as this model demonstrates economic and social efficiency in the development of gas supply in relation to public services obligation and in the control of the import dependence risk in the gas sector, no reform can be brought about by endogenous factors. The analysis of the French gas industry transition consists of four sections. After a survey of its historical development, the author presents its organisation and regulation under the public service model and its performances in terms of social and economic efficiency. In the third section, the minimalist reform for transcribing the European Directive in the French law is presented, in order to identify its potential effects in terms of competition development and public service erosion. Finally, in the fourth section, the industrial policy option to preserve the existence of a French mono-energy company and its consequences in terms of strategic adaptation are discussed. (A.L.B.)

    Throughout the United States, public health leaders are experimenting with how best to integrate services for individuals with complex needs. To that end, North Carolina implemented a policy incorporating both local public health departments and other providers into medical homes for low income pregnant women and young children at risk of developmental delays. To understand how this transition occurred within local communities, a pre-post comparative case study was conducted. A total of 42 people in four local health departments across the state were interviewed immediately before the 2011 policy change and six months later: 32 professionals (24 twice) and 10 pregnant women receiving case management at the time of the policy implementation. We used constant comparative analysis of interview and supplemental data to identify three key consequences of the policy implementation. One, having medical homes increased the centrality of other providers relative to local health departments. Two, a shift from focusing on personal relationships toward medical efficiency diverged in some respects from both case managers' and mothers' goals. Three, health department staff re-interpreted state policies to fit their public health values. Using a political economy perspective, these changes are interpreted as reflecting shifts in public health's broader ideological environment. To a large extent, the state successfully induced more connection between health department-based case managers and external providers. However, limited provider engagement may constrain the implementation of the envisioned medical homes. The increased focus on medical risk may also undermine health departments' role in supporting health over time by attenuating staff relationships with mothers. This study helps clarify how state public health policy innovations unfold at local levels, and why front line practice may in some respects diverge from policy intent. Published by Elsevier Ltd.

    An overview of the current status of wheelchair transportation safety in fixed route and demand-responsive, non-rail, public transportation vehicles within the US is presented. A description of each mode of transportation is provided, followed by a discussion of the primary issues affecting safety, accessibility, and usability. Technologies such as lifts, ramps, securement systems, and occupant restraint systems, along with regulations and voluntary industry standards have been implemented with the intent of improving safety and accessibility for individuals who travel while seated in their wheeled mobility device (e.g., wheelchair or scooter). However, across both fixed route and demand-responsive transit systems a myriad of factors such as nonuse and misuse of safety systems, oversized wheeled mobility devices, vehicle space constraints, and inadequate vehicle operator training may place wheeled mobility device (WhMD) users at risk of injury even under non-impact driving conditions. Since WhMD-related incidents also often occur during the boarding and alighting process, the frequency of these events, along with factors associated with these events are described for each transit mode. Recommendations for improving WhMD transportation are discussed given the current state of

    This study explored health organizations' public relations efforts to frame health issues through their press releases. Content analysis of 316 press releases from three health organizations-the American Heart Association, the American Cancer Society, and the American Diabetes Association-revealed that they used the medical research frame most frequently and emphasized societal responsibility for health issues. There were differences, however, among the organizations regarding the main frames and health issues: the American Diabetes Association was more likely to focus on the issues related to social support and education, while the American Heart Association and the American Cancer Society were more likely to address medical research and scientific news. To demonstrate their initiatives for public health, all the organizations employed the social support/educational frame most frequently. Researchers and medical doctors frequently were quoted as trusted sources in the releases.

    Full Text Available Background: In response to traditional zoning codes that contribute to car-dependent, sprawling, and disconnected neighborhoods, communities are reforming their land use laws to create pedestrian-friendly areas that promote physical activity. One such reform is the adoption of transit-oriented developments or districts (TODs. TODs are higher-density, compact, mixed use areas located around transit stops that are designed to encourage walking.Purpose: To identify the characteristics of communities that have adopted TODs in their land use laws and examine if communities that have included TODs in their zoning codes are more likely to have adults that commute by any form of active transportation (i.e., walking, biking, or public transportation or by using public transportation specifically.Methods: Zoning codes effective as of 2010 were obtained for a purposeful sample of the largest 3,914 municipal jurisdictions located in 473 of the most populous US counties and consolidated cities within 48 states and the District of Columbia. They were evaluated to determine whether they included TOD districts or regulations using a coding tool developed by the study team. Descriptive statistics together with t-tests and Pearson’s chi-squared independence test were used to compare characteristics of jurisdictions with and without TOD zoning. Multivariate linear regressions were used to compute the adjusted association between TOD zoning and taking public or active transportation to work.Results: Jurisdictions with TOD zoning were located more in the South and West than non-TOD jurisdictions and were more populous, higher income, more racially diverse, and younger. Jurisdictions with TOD zoning had significantly higher percentages of occupied housing with no vehicle than those without TOD zoning. TOD zoning was associated with significantly higher rates of public transportation to work (β=2.10, 95% CI=0.88, 3.32 and active transportation to work (β=2.48, 95

    Within the context of international public health, 'global health' seems to be emerging as a recognized term of preference. This article presents a critical analysis of the meaning and importance of 'global health' and situates its growing popularity within a historical context. A specific focus of this work is the role of the World Health Organization - WHO in both 'international' and 'global' health, and as na agent of transition from one to the other. Between 1948 and 1998, the WHO went through a period of hardship as it came up against an organizational crisis, budget cuts and a diminished status, especially when confronted with the growing influence of new, power players like the World Bank. We suggest that the WHO has responded to this changing international context by inititating its own process of restructuring and repositioning as an agent for coordinating, strategically planning and leading 'global health' initiatives.

    Full Text Available To satisfy the demand of low-carbon transportation, this paper studies the optimization of public transit network based on the concept of low carbon. Taking travel time, operation cost, energy consumption, pollutant emission, and traffic efficiency as the optimization objectives, a bilevel model is proposed in order to maximize the benefits of both travelers and operators and minimize the environmental cost. Then the model is solved with the differential evolution (DE algorithm and applied to a real network of Baoji city. The results show that the model can not only ensure the benefits of travelers and operators, but can also reduce pollutant emission and energy consumption caused by the operations of buses, which reflects the concept of low carbon.

    The development of personalized medicine is tightly linked with the correct exploitation of molecular data, especially those associated with the genome sequence along with these use of genomic data there is an increasing demand to share these data for research purposes. Transition of clinical data to research is based in the anonymization of these data so the patient cannot be identified, the use of genomic data poses a great challenge because its nature of identifying data. In this work we have analyzed current methods for genome anonymization and propose a one way encryption method that may enable the process of genomic data sharing accessing only to certain regions of genomes for research purposes.

    This essay reports on the final session of a 2-day workshop entitled 'Genetic Diversity and Science Communication', hosted by the CIHR Institute of Genetics in Toronto, April 2006. The first speaker, Timothy Caulfield, introduced the intersecting communities that promulgate a 'cycle of hype' of the timelines and expected outcomes of the Human Genome Project (HGP): scientists, the media and the public. Other actors also contribute to the overall hype, the social science and humanities communities, industry and politicians. There currently appears to be an abatement of the overblown rhetoric of the HGP. As pointed out by the second speaker, Sharon Kardia, there is broad recognition that most phenotypic traits, including disease susceptibility are multi-factorial. That said, George Davey-Smith reminded us that some direct genotype-phenotype associations may be useful for public health issues. The Mendelian randomization approach hopes to revitalize the discipline of epidemiology by strengthening causal influences about environmentally modifiable risk factors. A more realistic informational environment paves the way for greater public engagement in science policy. Two such initiatives were presented by Kardia and Jason Robert, and Peter Finegold emphasized that science education and professional development for science teachers are important components of later public engagement in science issues. However, pressures on public research institutions to commercialize and seek industry funding may have negative impacts in both encouraging scientists to inappropriately hype research and on diminishing public trust in the scientific enterprise. The latter may have a significant effect on public engagement processes, such as those proposed by Robert and Kardia.

    The single-stranded DNA (ssDNA) parvoviruses enter host cells through receptor-mediated endocytosis, and infection depends on processing in the early to late endosome as well as in the lysosome prior to nuclear entry for replication. However, the mechanisms of capsid endosomal processing, including the effects of low pH, are poorly understood. To gain insight into the structural transitions required for this essential step in infection, the crystal structures of empty and green fluorescent protein (GFP) gene-packaged adeno-associated virus serotype 8 (AAV8) have been determined at pH values of 6.0, 5.5, and 4.0 and then at pH 7.5 after incubation at pH 4.0, mimicking the conditions encountered during endocytic trafficking. While the capsid viral protein (VP) topologies of all the structures were similar, significant amino acid side chain conformational rearrangements were observed on (i) the interior surface of the capsid under the icosahedral 3-fold axis near ordered nucleic acid density that was lost concomitant with the conformational change as pH was reduced and (ii) the exterior capsid surface close to the icosahedral 2-fold depression. The 3-fold change is consistent with DNA release from an ordering interaction on the inside surface of the capsid at low pH values and suggests transitions that likely trigger the capsid for genome uncoating. The surface change results in disruption of VP-VP interface interactions and a decrease in buried surface area between VP monomers. This disruption points to capsid destabilization which may (i) release VP1 amino acids for its phospholipase A2 function for endosomal escape and nuclear localization signals for nuclear targeting and (ii) trigger genome uncoating.

    The 86 th annual meeting of the Georgia Public Health Association (GPHA) and joint conference with the Southern Health Association was held in Atlanta, Georgia, on April 13-14, 2015, with pre-conference (April 12 th ) and post-conference (April 14 th ) Executive Board meetings. As Georgia's leading forum for public health researchers, practitioners, and students, the annual meeting of the GPHA brings together participants from across the state to explore recent developments in the field and to exchange techniques, tools, and experiences. Historically, the GPHA conference has been held in Savannah (n=24); Jekyll Island (n=20); Atlanta (n=16); Augusta (n=4); and Gainesville (n=1). There was no annual meeting during the early years (1929-1936); during World War II (1941-1943 and 1945); and for four years during the 1980s. Between 2006 and 2010, GPHA held one-day annual meetings and business sessions with educational workshops. Several new initiatives were highlighted as part of this year's conference. These included a "move and groove" physical activity lounge, registration scholarships for students with a dedicated meet-and-greet reception, an expanded exhibit hall, presentation and approval of three resolutions (related to healthy foods at official activities and events; weapons at official activities and events; and memorials), and approval of the 2015 legislative policy positions and amended association bylaws. The theme for the conference was Advocacy in Action for Public Health . Specifically, the program addressed ensuring access to care; protecting funding for core programs, services, and infrastructure; eliminating health disparities; and addressing key public health issues important to the state of Georgia. One hundred and nine (109) abstracts were submitted for peer review; 36 were accepted for poster and 40 for workshop presentations. Four plenary sessions with keynote speakers covered the intersection between advocacy and policy, Georgia's response to the

    Full Text Available Recently, the number of studies involving complex network applications in transportation has increased steadily as scholars from various fields analyze traffic networks. Nonetheless, research on rail network growth is relatively rare. This research examines the evolution of the Public Urban Rail Transit Networks of Kuala Lumpur (PURTNoKL based on complex network theory and covers both the topological structure of the rail system and future trends in network growth. In addition, network performance when facing different attack strategies is also assessed. Three topological network characteristics are considered: connections, clustering and centrality. In PURTNoKL, we found that the total number of nodes and edges exhibit a linear relationship and that the average degree stays within the interval [2.0488, 2.6774] with heavy-tailed distributions. The evolutionary process shows that the cumulative probability distribution (CPD of degree and the average shortest path length show good fit with exponential distribution and normal distribution, respectively. Moreover, PURTNoKL exhibits clear cluster characteristics; most of the nodes have a 2-core value, and the CPDs of the centrality's closeness and betweenness follow a normal distribution function and an exponential distribution, respectively. Finally, we discuss four different types of network growth styles and the line extension process, which reveal that the rail network's growth is likely based on the nodes with the biggest lengths of the shortest path and that network protection should emphasize those nodes with the largest degrees and the highest betweenness values. This research may enhance the networkability of the rail system and better shape the future growth of public rail networks.

    To calculate associated costs with dental studies (ACDS) in a public university. We performed a cross-sectional study using a costing system on a random sample of 376 dental students enrolled at any semester in a public university. To calculate ACDS (Mexican pesos of 2009-1), we used a questionnaire divided into eight sections. Sociodemographic and socioeconomic variables, housing costs, food, transportation, instruments and equipment, as well as remunerations associated with patient care along 16 weeks of classes in each semester were included. We used linear regression. The average of ACDS was of 18,357.54 ± 12,746.81 Mexican pesos. The largest percentage of ACDS (30.2 %) was for clinical instruments (5,537.66 ± 6,260.50). Students also spent funds in paying to patients for their time during care delivered (2,402.11 ± 4,796.50). Associated variables (p 〈 0.001) with the ACDS were having completed at least one clinical course or one theoretical-practical course, living within the state or out of state (compared to students who live in the city where dental studies take place), and being enrolled in the more advanced dental studies. The results indicate that a significant percentage of the cost to students (13.1 %) is related with clinical care delivery.

    Inspired by the missing (new) link prediction and the spurious existing link identification in link prediction theory, this paper establishes an auxiliary optimization method for public transit route network (PTRN) based on link prediction. First, link prediction applied to PTRN is described, and based on reviewing the previous studies, the summary indices set and its algorithms set are collected for the link prediction experiment. Second, through analyzing the topological properties of Jinan’s PTRN established by the Space R method, we found that this is a typical small-world network with a relatively large average clustering coefficient. This phenomenon indicates that the structural similarity-based link prediction will show a good performance in this network. Then, based on the link prediction experiment of the summary indices set, three indices with maximum accuracy are selected for auxiliary optimization of Jinan’s PTRN. Furthermore, these link prediction results show that the overall layout of Jinan’s PTRN is stable and orderly, except for a partial area that requires optimization and reconstruction. The above pattern conforms to the general pattern of the optimal development stage of PTRN in China. Finally, based on the missing (new) link prediction and the spurious existing link identification, we propose optimization schemes that can be used not only to optimize current PTRN but also to evaluate PTRN planning.

    1998-09-01

    This study examined options for compensating for the shortages of money for public pensions due to population aging in Japan: increases in pension contributions, consumption pension taxes, interest income pension taxes, and inheritance pension taxes. The analysis relied on simulation in an expanded life cycle growth model. Data were obtained from 1992 estimations of population by the Institute of Population Problems of the Ministry of Health and Welfare. This study is unique in its use of real population data for the simulations and in its use of transition states. The analysis begins with a description of the altered Overlapping Generations Model by Auerback and Kotlikoff (1983). The model accounts for the inaccuracy of lifetime and liquidity constraints and ordinary budget constraints and reproduces the consumption-savings profiles of older people and incorporates wage income taxation and other forms of taxation. Income includes wage and interest income. The analysis includes a description of the method of simulation, assumptions, and evaluation of the effects of population aging. It is assumed that narrower government sector spending on general expenditures per worker will increase by 1% every year. It is concluded that national saving rates will probably decrease due to population aging. The lowest levels of capital stock and savings will result from higher pension contributions. The highest level of capital stock will result from higher consumption pension taxes during 1990-2015. Preferred policies should focus on increasing interest income rates.

    Federal funding initiatives for local infrastructure and capacity building was discussed with particular reference to the unique partnerships between the Canada-British Columbia Agreement on the transfer of federal gas tax revenues and the Canada-British Columbia agreement on the transfer of funds for public transit. The agreements reflect the nature of intergovernmental relations in British Columbia where the Union of British Columbia Municipalities (UBCM) works together with both federal and provincial governments to promote sustainable communities. This report identified the initiatives that are underway in communities across British Columbia as they begin to implement Gas Tax and Public Transit funded projects. These projects span a broad range of eligible project categories. The leadership role taken by local governments in the province to reduce greenhouse gas emissions was highlighted. Some of the 141 projects reported in 2007 were highlighted in this report, including improvement to public transit in the District of Saanich; TransLink bus replacement and expansion; cycling and pedestrian infrastructure; improvements to local roads and bridges; alternative energy retrofits; collection of solid waste; improvement to water systems; stormwater and wastewater treatment; capacity building; watershed protection; and water acquisition strategies. Of the projects reported, 33 per cent anticipated gas tax spending in more than 1 year, indicating either payment of capital costs as they are incurred during a construction period that spans beyond a single year, or use of gas tax funding towards the debt servicing costs related to the eligible project. tabs., figs

    Forming secure friendship attachments during adolescence are important for mental health; few, however, have specifically examined the ways in which the transitions in attachment during adolescence may influence future mental health outcomes among African Americans. The present study examines how transitions in attachment in adolescence predicted changes in depression symptoms from late adolescents through adulthood in an African-American sample. We used growth curve modeling to examine the association between transitions in friendship attachment and changes in depression symptoms in adulthood. At age 16 years, 346 (64.0%) adolescents reported secure attachment with 195 (36.0%) reporting either avoidant or resistant attachment. At age 17 years, 340 (62.9%) reported secure attachment and 201 (37.2%) reported avoidant or resistant attachment. The largest percentage of participants (46.2%) reported stable-secure attachment across the two time points. Results of the growth model indicated that adolescents who reported a stable-secure attachment style had lower levels of depression symptoms during adulthood than those individuals who transitioned from secure-to-insecure, from insecure-to-secure, or were in the stable-insecure group. Interestingly enough, individuals in both the attachment transition groups had a faster declining rate of depression symptoms over time compared to the two stability groups. Data support existing research showing an association between transitions in attachment during adolescence and depression through adulthood. Furthermore, these study findings suggest there may be protective features associated with transitioning between attachment styles during adolescence on later depression, compared to African Americans who remain stable in their attachment style.

    As diagnosis and treatment of unruptured intracranial aneurysms continues to increase, management principles remain largely based on size. This is despite mounting evidence that aneurysm location and other morphologic variables could play a role in predicting overall risk of rupture. Morphological parameters can be divided into 3 main groups, those that are intrinsic to the aneurysm, those that are extrinsic to the aneurysm, and those that involve both the aneurysm and surrounding vasculature (transitional). We present an evaluation of intrinsic, transitional, and extrinsic factors and their association with ruptured aneurysms. Using preoperative computed tomographic angiography, we generated 3-dimensional models of aneurysms and their surrounding vasculature with Slicer software. Using univariate and multivariate analyses, we examined the association of intrinsic, transitional, and extrinsic aspects of aneurysm morphology with rupture. Between 2005 and 2013, 227 cerebral aneurysms in 4 locations were evaluated/treated at a single institution, and computed tomographic angiographies of 218 patients (97 unruptured and 130 ruptured) were analyzed. Ruptured aneurysms analyzed were associated with clinical factors of absence of multiple aneurysms and history of no prior rupture, and morphologic factors of greater aspect ratio. On multivariate analysis, aneurysm rupture remained associated with history of no prior rupture, greater flow angle, greater daughter-daughter vessel angle, and smaller parent-daughter vessel angle. By studying the morphology of aneurysms and their surrounding vasculature, we identified several parameters associated with ruptured aneurysms that include intrinsic, transitional, and extrinsic factors of cerebral aneurysms and their surrounding vasculature.

    Research has identified several factors that affect fear of crime in public space. However, the extent to which gender moderates the effectiveness of fear-reducing measures has received little attention. Using data from the Chicago Transit Authority Customer Satisfaction Survey of 2003, this study aims to understand whether train transit security practices and service attributes affect men and women differently. Findings indicate that, while the presence of video cameras has a lower effect on women's feelings of safety compared with men, frequent and on-time service matters more to male passengers. Additionally, experience with safety-related problems affects women significantly more than men. Conclusions discuss the implications of the study for theory and gender-specific policies to improve perceptions of transit safety.

    Full Text Available Subclinical laminitis has been responsible for economic losses in dairy industry; thus, its diagnostic    is very important to prevent negative responses to milk production industry. The aim of this study  was to identify lesions associated with subclinical laminitis during the transition period with presence or absence of radiographic signs linked to this disease in Holstein cows. The cows were evaluated during the transition period and categorized into two groups (with and without laminitis according to the lesions associated with this subclinical disease. The radiological dynamic was performed in two target points during the transition period (prepartum and postpartum, with the objective of determining capsular position possible alterations and third phalanx bone degeneration (F3. There was no effect of the presence of lesions associated with subclinical laminitis regarding the position of the third phalanx to the hoof wall (p>0.05. Significant radiographic angular differences (p0.05. Overall, this study did not show radiographic signs of phalangeal misalignment in the hoof of dairy cows with lesions associated with subclinical laminitis during the transition period .

    This research paper aims to assess factors reported by parents associated with the successful transition of children with complex additional support requirements that have undergone a transition between school environments from 8 European Union member states. Quantitative data were collected from 306 parents within education systems from 8 EU member states (Bulgaria, Cyprus, Greece, Ireland, the Netherlands, Romania, Spain and the UK). The data were derived from an online questionnaire and consisted of 41 questions. Information was collected on: parental involvement in their child's transition, child involvement in transition, child autonomy, school ethos, professionals' involvement in transition and integrated working, such as, joint assessment, cooperation and coordination between agencies. Survey questions that were designed on a Likert-scale were included in the Principal Components Analysis (PCA), additional survey questions, along with the results from the PCA, were used to build a logistic regression model. Four principal components were identified accounting for 48.86% of the variability in the data. Principal component 1 (PC1), 'child inclusive ethos,' contains 16.17% of the variation. Principal component 2 (PC2), which represents child autonomy and involvement, is responsible for 8.52% of the total variation. Principal component 3 (PC3) contains questions relating to parental involvement and contributed to 12.26% of the overall variation. Principal component 4 (PC4), which involves transition planning and coordination, contributed to 11.91% of the overall variation. Finally, the principal components were included in a logistic regression to evaluate the relationship between inclusion and a successful transition, as well as whether other factors that may have influenced transition.

    Poor health outcomes from insufficient physical activity (PA) are a persistent public health issue. Public transit is often promoted for positive influence on PA. Although there is cross-sectional evidence that transit users have higher PA levels, this may be coincidental or shifted from activities such as recreational walking. We use a quasi-experimental design to test if light rail transit (LRT) generated new PA in a neighborhood of Salt Lake City, Utah, USA. Participants (n=536) wore Global Positioning System (GPS) receivers and accelerometers before (2012) and after (2013) LRT construction. We test within-person differences in individuals' PA time based on changes in transit usage pre- versus post-intervention. We map transit-related PA to detect spatial clustering of PA around the new transit stops. We analyze within-person differences in PA time based on daily transit use and estimate the effect of daily transit use on PA time controlling for socio-demographic variables. Results suggest that transit use directly generates new PA that is not shifted from other PA. This supports the public health benefits from new high quality public transit such as LRT.

  10. Anelasticity maps for acoustic dissipation associated with phase transitions in minerals

    Science.gov (United States)

    Carpenter, Michael A.; Zhang, Zhiying

    2011-07-01

    Acoustic dissipation due to structural phase transitions in minerals could give rise to large seismic attenuation effects superimposed on the high temperature background contribution from dislocations and grain boundaries in the Earth. In addition to the possibility of a sharp peak actually at a transition point for both compressional and shear waves, significant attenuation might arise over wider temperature intervals due to the mobility of transformation twins or other defects associated with the transition. Attenuation due to structural phase transitions in quartz, pyroxenes, perovskites, stishovite and hollandite, or to spin state transitions of Fe2+ in magnesiowüstite and perovskite and the hcp/bcc transition in iron-nickel (Fe-Ni) alloy, are reviewed from this perspective. To these can be added possible loss behaviour associated with reconstructive transitions which might occur by a ledge mechanism on topotactic interfaces (orthopyroxene/clinopyroxene, olivine/spinel and perovskite/postperovskite), with impurities (Snoek effect) or with mobility of protons. There are experimental difficulties associated with measuring dissipation effects in situ at simultaneous high pressures and temperatures, so reliance is currently placed on investigation of analogue phases such as LaCoO3 for spin-state behaviour and LaAlO3 for the dynamics of ferroelastic twin walls. Similarly, it is not possible to measure loss dynamics simultaneously at the low stresses and low frequencies that pertain in seismic waves, so reliance must be placed on combining different techniques, such as dynamic mechanical analysis (low frequency, relatively high stress) and resonant ultrasound spectroscopy (high frequency, low stress), to extrapolate acoustic loss behaviour over wide frequency, temperature and stress intervals. In this context 'anelasticity maps' provide a convenient means of representing different loss mechanisms. Contouring of the inverse mechanical quality factor, Q-1, can be

    In the densely populated metropolitan area, empirical studies have found that overcrowding inside transit vehicles has become substantially worse and worse over recent years. Chronic in-vehicle crowding is not only caused by a lack of physical infrastructure, but also triggered by inadequate service provisions. Given the prevalence of overcrowded transit vehicles, this paper conducts both quantitative and qualitative studies, especially focusing on remodeling the in-vehicle crowding cost func...

    Given the public health importance of law modernization, we undertook a comparative analysis of policy efforts in 4 states (Alaska, South Carolina, Wisconsin, and Nebraska) that have considered public health law reform based on the Turning Point Model State Public Health Act. Through national legislative tracking and state case studies, we investigated how the Turning Point Act's model legal language has been considered for incorporation into state law and analyzed key facilitating and inhibiting factors for public health law reform. Our findings provide the practice community with a research base to facilitate further law reform and inform future scholarship on the role of law as a determinant of the public's health.

    2016-07-01

    School transition at around 11-years of age can be anxiety-provoking for children, particularly those with special educational needs (SEN). The present study adopted a longitudinal design to consider how existing transition strategies, categorized into cognitive, behavioral or systemic approaches, were associated with post-transition anxiety amongst 532 typically developing children and 89 children with SEN. Multiple regression analysis indicated that amongst typically developing pupils, systemic interventions were associated with lower school anxiety but not generalized anxiety, when controlling for prior anxiety. Results for children with SEN differed significantly, as illustrated by a Group × Intervention type interaction. Specifically, systemic strategies were associated with lower school anxiety amongst typically developing children and higher school anxiety amongst children with SEN. These findings highlight strategies that schools may find useful in supporting typically developing children over the transition period, whilst suggesting that children with SEN might need a more personalized approach.

    2017-01-01

    Objective The study examines family caregivers’ health changes over 1 year on four health dimensions and explores the association of differential health trajectories with adult day service (ADS) use and caregiving transitions. Method The participants were 153 primary caregivers of individuals with dementia (IWDs) who provided information on care situations and their own health at baseline, 6-month, and 12-month interviews. Results Caregivers showed increasing functional limitations and decreasing bodily pain over time, whereas role limitation and general health perception remained stable. Furthermore, caregivers’ trajectories of functional limitation were associated with their extent of ADS use at baseline and their relatives’ placement. Discussion Health is multidimensional; all dimensions of caregiver health do not change in a uniform manner. The findings underscore the importance of the association of caregiving transitions and caregiver health and the potential health benefits of ADS use for family caregivers. PMID:25348275

    Detailed comparison of factors associated with abnormal approach to the prominent and with escalation from communication to approach has not hitherto been undertaken. This partially reflects the failure of individual studies to adopt compatible terminologies. This study involves a careful dissection of six public figure studies, three involving U.S. politicians, two Hollywood celebrities, and one the British Royal Family. Common findings were unearthed across six headings. Approachers were significantly more likely to exhibit serious mental illness, engage in multiple means of communication, involve multiple contacts/targets, and to incorporate into their communication requests for help. They were significantly less likely to use threatening or antagonistic language in their communications, except in those cases involving security breaches. These results emphasize the importance of integrating mental health findings and preventive measures into risk management. Approach should not be regarded as a single behavioral category and has multiple motivations. Future studies should adopt standard terminology, preferably taken from the general stalking research. © 2010 American Academy of Forensic Sciences.

    Full Text Available The article discusses the theory and practice of the implementation and development of transport and transit potential (TTP of Russia. This could be an effective way to replace the natural resource rent as the main source of income for the state and economic actors. For the modernization of national economic system the key importance are innovative technologies in the development of transport and transit potential through the organization of the production of goods and services with the highest added value in Russia. We proposed and substantiated the hypothesis about the necessity of creation of a Federal company responsible for the financing and implementation of Russia’s transport and transit potential development projects on the principles of public-private partnership (PPP. The authors have revealed the economic, institutional and organizational prerequisites for the establishment of such a public-private partnership company. We have provided the opinions of scientists and experts showing the urgent need to create in one form or another a single operator to transport goods on the territory of Russia and the Eurasian economic Union. To prove the hypothesis, we presented a description and analysis of the factors affecting the value of transit freight transport on Euro-Asian routes. We paid the special attention to identify the reasons of the increasing competitive advantage of Maritime transport in the world’s goods movement system. The authors based the main conclusion that, first of all, the created publicprivate partnership company should be large due to tough competition of developing transit freight by land routes with the global Maritime container services. Secondly, it needs a significant state participation since the management of the world’s cargo flows requires the effort of foreign policy and geo-economic nature. We emphasized that this business entity would become an active proponent and lobbyist of the most effective

    2016-01-01

    This book shows how transit assignment models can be used to describe and predict the patterns of network patronage in public transport systems. It provides a fundamental technical tool that can be employed in the process of designing, implementing and evaluating measures and/or policies to improve the current state of transport systems within given financial, technical and social constraints. The book offers a unique methodological contribution to the field of transit assignment because, moving beyond “traditional” models, it describes more evolved variants that can reproduce: • intermodal networks with high- and low-frequency services; • realistic behavioural hypotheses underpinning route choice; • time dependency in frequency-based models; and • assumptions about the knowledge that users have of network conditions that are consistent with the present and future level of information that intelligent transport systems (ITS) can provide. The book also considers the practical perspective of practit...

    Full Text Available

    Background: The public health services project of the South-eastern Europe health network has undertaken an evaluation of public health services in its nine member countries. The purpose of the evaluation of public health services provision in the South-eastern European (SEE countries is to understand where these countries now stand in public health, the institutional, organisational, legislative and service delivery developments that are taking place and to identify strengths and weaknesses in their public health systems and services in order to inform decision making about investment and future reform.

    Methods: The evaluation was orientated around “essential public health operations” that are deemed to form the core of public health activities and services and to be indispensable to the delivery of modern public health services in any country. The evaluation analysed these activities and services within the structure of the health system functions of stewardship, resource generation, financing and service delivery, as developed by WHO.

    Results: The results demonstrate a mixed picture of strengths and weaknesses within the context of significant social, economic and political challenges in the region. Among the many visible and significant strengths in public health services in the region are well developed networks of public health institutes with well defined surveillance systems, highly experienced and well educated public health professionals as well as many positive examples of service delivery. But there are also many concerns and challenges, not the least of which is political focus, direction and support for modern public health services, as well as funding. Collaboration and partnership among sectors is weak and information and communication systems are inadequate and not sufficiently integrated.

    Conclusions: Having emphasized the main weak and

    The characteristics of ten Canadian cities and their transportation systems were summarized. The need to conserve resources and to maintain environmental quality has lead to initiatives aimed at achieving more sustainable urban transportation. The most promising initiatives to reduce greenhouse gas emissions and achieve other sustainability objectives were described. Ways to overcome the most significant barriers were suggested. Since suburban areas are generally automobile-dependant, the major challenge is how to retrofit these areas with high quality transit services. A corollary objective is to achieve more compact, mixed-use urban structure and pedestrian-friendly streetscapes, thereby reducing average trip distances and making it feasible for the transit, walking and cycling modes to be used more extensively. refs., tabs., figs

    Responding to the growing gap between the sociological ethos and the world we study, the challenge of public sociology is to engage multiple publics in multiple ways. These public sociologies should not be left out in the cold, but brought into the framework of our discipline. In this way we make public sociology a visible and legitimate enterprise, and, thereby, invigorate the discipline as a whole. Accordingly, if we map out the division of sociological labor, we discover antagonistic interdependence among four types of knowledge: professional, critical, policy, and public. In the best of all worlds the flourishing of each type of sociology is a condition for the flourishing of all, but they can just as easily assume pathological forms or become victims of exclusion and subordination. This field of power beckons us to explore the relations among the four types of sociology as they vary historically and nationally, and as they provide the template for divergent individual careers. Finally, comparing disciplines points to the umbilical chord that connects sociology to the world of publics, underlining sociology's particular investment in the defense of civil society, itself beleaguered by the encroachment of markets and states.

    2014-12-01

    Full Text Available The article analyzes reconstruction dynamics of the Public Prosecutor’s Office, focusing on the mobilization of prosecutors and prosecuting attorney in the period from 1974 to 1985. We argue that the characteristics of Brazilian political transition were critical to the changing process of the institution, which gained constitutional status in 1988. Liberalization of the military regime changed the links between lawyers, opposition parties and pro-democracy movements. The connection of the institutional movement with dissident political elites and the dense activism network around new social conflicts allowed the Public Prosecutor’s Office to try new strategies of collective action, gain political visibility and thus become a viable alternative to political system to respond to social pressures for judiciary democratization.

    2001-12-01

    We calculate the partial molar volumes and their changes associated with the coil(extended)-to-helix transition of two types of peptide, glycine-oligomer and glutamic acid-oligomer, in aqueous solutions by using the Kirkwood-Buff solution theory coupled with the three-dimensional reference interaction site model (3D-RISM) theory. The volume changes associated with the transition are small and positive. The volume is analyzed by decomposing it into five contributions following the procedure proposed by Chalikian and Breslauer: the ideal volume, the van der Waals volume, the void volume, the thermal volume, and the interaction volume. The ideal volumes and the van der Waals volumes do not change appreciably upon the transition. In the both cases of glycine-peptide and glutamic acid-peptide, the changes in the void volumes are positive, while those in the thermal volumes are negative, and tend to balance those in the void volumes. The change in the interaction volume of glycine-peptide does not significantly contribute, while that of glutamic acid-peptide makes a negative contribution. Copyright 2001 John Wiley & Sons, Inc.

    Full Text Available Abstract Background Associations between body weight, physical activity and dietary intake among a population of metropolitan transit workers are described. Methods Data were collected during October through December, 2005, as part of the baseline measures for a worksite weight gain prevention intervention in four metro transit bus garages. All garage employees were invited to complete behavioral surveys that assessed food choices and physical activity, and weight and height were directly measured. Seventy-eight percent (N = 1092 of all employees participated. Results The prevalence of obesity (BMI >= 30 kg/m2 was 56%. Over half of the transit workers reported consuming fruit (55% and vegetables (59% ≥ 3/week. Reported fast food restaurant frequency was low (13% visited ≥ 3/week. Drivers reported high levels of physical activity (eg. walking 93 minutes/day. However, an objective measure of physical activity measured only 16 minutes moderate/vigorous per day. Compared to other drivers, obese drivers reported significantly less vigorous physical activity, more time sitting, and more time watching television. Healthy eating, physical activity and weight management were perceived to be difficult at the worksite, particularly among obese transit workers, and perceived social support for these behaviors was modest. However, most workers perceived weight management and increased physical activity to be personally important for their health. Conclusion Although transit workers' self-report of fruit and vegetable intake, and physical activity was high, perceived access to physical activity and healthful eating opportunities at the worksite was low. Obese workers were significantly less physically active and were more likely to report work environmental barriers to physical activity.

    1977-01-01

    The series of questions concerning public relations, connected with the realization of power plant construction projects will be discussed before the background of the public requirement of electricity supply corporations. It will be explained that public relation cannot be seen as an instrument, having the purpose to inform about 'good or bad' of power plant designs and construction intentions. PR is more a constitutive element of economy policy. Transparent, clear information of the citizen about power plant projects, and power plant related procedures should be their targets. This signifies a distance from just technical presentation. PR must develop in the direction to active corporational strategy, taking psychological- and social psychological influences into consideration. Statements will be made in regard to the dialogue between power plant advocates and power plant opponents. The special responsibility of the public electricity supply corporations for an always sufficient, safe and economical supply to the consumer, will be pointed out. Better information of the public in this regard is a necessary requirement. (orig.) [de

    Ireland experienced a period of major political and social change between 1957 and 1977 which included the redefinition of the role and status of women and the creation of a new public policy paradigm. By 1977 the main features of this public policy paradigm were in place in the form of an ‘equality contract’. The ‘equality contract’ granted formal legal equality to married women in family law and procedural equality to all women in relation to employment. This replaced the hirarchically base...

    This report analyzes in a preliminary way the risks to the public posed by the CANDU nuclear fuel cycle. Part 1 considers radiological risks, while part 2 (published as INFO-0141-2) evaluates non-radiological risks. The report concludes that, for radiological risks, maximum individual risks to members of the public are less than 10 -5 per year for postulated accidents, are less than 1 percent of regulatory limits for normal operation and that collective doses are small, less than 3 person-sieverts. It is also concluded that radiological risks are much smaller than the non-radiological risks posed by activities of the nuclear fuel cycle

    Public policy implications for Arizona of the School-to-Work Opportunities Act are explored, specifically with regard to rural areas. It is argued that should additional resources become available to the state, population-based allocations to rural areas are likely to be insufficient for meaningful educational and economic-development reform.

    Understanding correlation between influential factors and insurance losses is beneficial for insurers to accurately price and modify the bonus-malus system. Although there have been a certain number of achievements in insurance losses and claims modeling, limited efforts focus on exploring the relative role of accidents characteristics in insurance losses. The primary objective of this study is to evaluate the influential priority of transit accidents attributes, such as the time, location and type of accidents. Based on the dataset from Washington State Transit Insurance Pool (WSTIP) in USA, we implement several key algorithms to achieve the objectives. First, K-means algorithm contributes to cluster the insurance loss data into 6 intervals; second, Grey Relational Analysis (GCA) model is applied to calculate grey relational grades of the influential factors in each interval; in addition, we implement Naive Bayes model to compute the posterior probability of factors values falling in each interval. The results show that the time, location and type of accidents significantly influence the insurance loss in the first five intervals, but their grey relational grades show no significantly difference. In the last interval which represents the highest insurance loss, the grey relational grade of the time is significant higher than that of the location and type of accidents. For each value of the time and location, the insurance loss most likely falls in the first and second intervals which refers to the lower loss. However, for accidents between buses and non-motorized road users, the probability of insurance loss falling in the interval 6 tends to be highest. PMID:29298337

    The paper explores how local public authorities can support and facilitate citizens’ participa-tion and learning in sustainable transition in urban neighbourhoods, by supporting local in-termediaries. The role of intermediaries can be performed by a variety of actors such as public housing...... associations; NGO´s, or semi public institutions. Our claim is that intermediary actors have the potential to facilitate new platforms for citizens’ participation in urban sustainable transition due to their particular role in between public authorities and civil society. The key question of the paper is how...... the intermediary actors facilitate citizens' participatory processes in sustainable urban transitions, and the paper explores the concept of institutional capacity building as a way to develop learning processes and new practises? The aim is to analyse approaches of creating platforms for involving citizens...

  1. Association of Transition Readiness to Intentional Self-Regulation and Hopeful Future Expectations in Youth With Illness.

    Little is known about how transition readiness relates to other developmental skills of adolescence in youth with chronic illness. Better understanding of how transition readiness relates to these other developmental skills could lead to a broader array of tools to improve transition readiness. Intentional self-regulation (ISR) and hopeful future expectations (HFE) are 2 developmental skills of adolescence that improve with participation in developmental programming and thus are modifiable. We explored associations between transition readiness, as measured by the Transition Readiness Assessment Questionnaire 29 (TRAQ-29) and ISR and HFE in youth with chronic illness recruited from a variety of subspecialty clinics from a major southeast medical center. A total of 71 adolescents with chronic illness were included in the analysis. The TRAQ-29 Self-Advocacy domain showed positive associations to both ISR (P = .03) and HFE (P = .009). In addition, the TRAQ-29 overall had positive associations to HFE (P = .04). The significant associations between TRAQ-29 Self-Advocacy domain scores and ISR and HFE suggest that transition readiness is developing within the context of other developmental areas in adolescence. More work is needed to see if the programming that improves these other developmental skills might also improve transition readiness. Copyright © 2016 Academic Pediatric Association.

    2017-01-01

    Brazil is currently experiencing a significant demographic transition characterized by a decrease in fertility rates and an exponential increase in the number of elderly citizens, which presents a special challenge for the health care professionals. More than other portions of the population, the elderly are most commonly affected by chronic diseases such as Parkinson's disease. Policymakers contend that Brazil is reasonably well-prepared regarding elderly health care, with policies that aim to ensure the quality of life and the well-being of this portion of the population. However, what happens in practice falls short of what the Brazilian Constitution sets forth. Specifically, there is a clear contradiction between what the law recognizes as being a citizen's rights and the implementation of guidelines. Because health financing in Brazil remains relatively low, the civil society tries to fill in the gaps as much as possible in the treatment of elderly patients suffering from chronic diseases such as Parkinson's disease. In this review, we outline the current legislation in Brazil regarding the elderly and in particular, patients with Parkinson's disease, in the context of a rapidly aging population.

    In an urban-transit bus, fueled by biodiesel in Toledo, Ohio, single inhalable particle samples in October 2008 were collected and detected by scanning electron microscopy and energy dispersive X-ray spectrometry (SEM/EDS). Particle size analysis found bimodal distribution at 0.2 and 0.5 microm. The particle morphology was characterized by 14 different shape clusters: square, pentagon, hexagon, heptagon, octagon, nonagon, decagon, agglomerate, sphere, triangle, oblong, strip, line or stick, and unknown, by quantitative order. The square particles were common in the samples. Round and triangle particles are more, and pentagon, hexagon, heptagon, octagon, nonagon, decagon, strip, line or sticks are less. Agglomerate particles were found in abundance. The surface of most particles was coarse with a fractal edge that can provide a suitable chemical reaction bed in the polluted atmospheric environment. The three sorts of surface patterns of squares were smooth, semi-smooth, and coarse. The three sorts of square surface patterns represented the morphological characteristics of single inhalable particles in the air inside the bus in Toledo. The size and shape distribution results were compared to those obtained for a bus using ultra low sulfur diesel.

    Full Text Available The greatest burden of cardiovascular disease is now carried by developing countries with cardiometabolic conditions such as metabolic syndrome, obesity and inflammation believed to be the driving force behind this epidemic. Dietary fiber is known to have protective effects against obesity, type 2 diabetes, cardiovascular disease and the metabolic syndrome. Considering the emerging prevalence of these cardiometabolic disease states across the epidemiologic transition, the objective of this study is to explore these associations of dietary fiber with cardiometabolic risk factors in four countries across the epidemiologic transition. We examined population-based samples of men and women, aged 25–45 of African origin from Ghana, Jamaica, the Seychelles and the USA. Ghanaians had the lowest prevalence of obesity (10%, while Jamaicans had the lowest prevalence of metabolic syndrome (5% across all the sites. Participants from the US presented with the highest prevalence of obesity (52%, and metabolic syndrome (22%. Overall, the Ghanaians consumed the highest dietary fiber (24.9 ± 9.7 g, followed by Jamaica (16.0 ± 8.3 g, the Seychelles (13.6 ± 7.2 g and the lowest in the USA (14.2 ± 7.1 g. Consequently, 43% of Ghanaians met the fiber dietary guidelines (14 g/1000 kcal/day, 9% of Jamaicans, 6% of Seychellois, and only 3% of US adults. Across all sites, cardiometabolic risk (metabolic syndrome, inflammation and obesity was inversely associated with dietary fiber intake, such that the prevalence of metabolic syndrome was 13% for those in the lowest quartile of fiber intake, compared to 9% those in the highest quartile of fiber intake. Notably, twice as many of participants (38% in the lowest quartile were obese compared to those in the highest quartile of fiber intake (18%. These findings further support the need to incorporate strategies and policies to promote increased dietary fiber intake as one component for the prevention of cardiometabolic

    Protoplanetary disks are where planets form, grow, and migrate to produce the diversity of exoplanet systems we observe in mature systems. Disks where this process has advanced to the stage of gap opening, and in some cases central cavity formation, have been termed pre-transitional and transitional disks in the hope that they represent intermediate steps toward planetary system formation. Recent reviews have focussed on disks where the star is of solar or sub-solar mass. In contrast to the sub-millimeter where cleared central cavities predominate, at H-band some T Tauri star transitional disks resemble primordial disks in having no indication of clearing, some show a break in the radial surface brightness profile at the inner edge of the outer disk, while others have partially to fully cleared gaps or central cavities. Recently, the Meeus Group I Herbig stars, intermediate-mass PMS stars with IR spectral energy distributions often interpreted as flared disks, have been proposed to have transitional and pre-transitional disks similar to those associated with solar-mass PMS stars, based on thermal-IR imaging, and sub-millimeter interferometry. We have investigated their appearance in scattered light as part of the Strategic Exploration of Exoplanets and Disks with Subaru (SEEDS), obtaining H-band polarimetric imagery of 10 intermediate-mass stars with Meeus Group I disks. Augmented by other disks with imagery in the literature, the sample is now sufficiently large to explore how these disks are similar to and differ from T Tauri star disks. The disk morphologies seen in the Tauri disks are also found for the intermediate-mass star disks, but additional phenomena are found; a hallmark of these disks is remarkable individuality and diversity which does not simply correlate with disk mass or stellar properties, including age, including spiral arms in remnant envelopes, arms in the disk, asymmetrically and potentially variably shadowed outer disks, gaps, and one disk

  6. Corporate and public governances in transition: the limits of property rights and the significance of legal institutions

    Directory of Open Access Journals (Sweden)

    Jean-François Nivet

    2004-12-01

    Full Text Available Post-socialist transition raises crucial issues about the institutional setting of a market economy. The priority has been given to property rights, and privatization has been advocated as a means to depoliticize economic activities. The dismissal of external interventions, allied with the attraction to the American model and Hayekian ideas, often led to the introduction of minimal laws and wait for their evolutionary development. The failure of corporate and public governance, notably in Russia, helps to show why, on the contrary, democratically established legal rules are essential. Legislation should not only protect corporate shareholders and stakeholders, but more fundamentally all citizens against predatory collusive behavior of political, economic and criminal elites

    2013-01-01

    State, county, and local governments are currently facing a myriad of economic issues, based on shrinking tax revenues combined with increased expenditures. Of these, the costs related to defined benefit pension plans are one of the most serious issues facing many public employers. Through a comprehensive review of the existing literature, this article examines how the shift from the defined benefit (DB) to defined contribution (DC) pension plan has the potential to enhance levels of labor unrest due to changes in union militancy, bargaining skills deficits, intra-organizational conflict, and issues related to economic trade-offs. Besides the capacity for immediate and deleterious ramifications in the collective bargaining process, the transition to the DC pension also presents some potentially negative consequences related to human resource management, including changes in the psychological contract, recruitment strategies, employee turnover, and changes in retirement patterns. Recommendations to improve labor relations and human resource management practices in the DC pension environment are also explored.

    Full Text Available This article analyzes the role of schools in educational choices in the transition to public high schools in Mexico City. Secondary schools have the potential to influence educational choices, through the development of certain educational functions. This influence comes in different ways, and is relatively independent of adscriptive characteristics and previous academic performance of students.  Schools serve i as agents contributing to decision making, facilitating continuity on educational trajectories ii or as instances that do not develop explicit actions aimed to link their students to any of the options offered in the post-secondary educational system. While some schools teaching resources are destined to accompany their students during their decision process, others lack of them, abandoning them in this crucial educational event. The article is based on data provided by an ethnographic study conducted in seven high schools in southern Mexico City between January and July 2012

    We find transient transit-like dimming events within the K2 time series photometry of the young star RIK-210 in the Upper Scorpius OB association. These dimming events are variable in depth, duration, and morphology. High spatial resolution imaging revealed that the star is single and radial velocity monitoring indicated that the dimming events cannot be due to an eclipsing stellar or brown dwarf companion. Archival and follow-up photometry suggest the dimming events are transient in nature. The variable morphology of the dimming events suggests they are not due to a single spherical body. The ingress of each dimming event is always shallower than egress, as one would expect for an orbiting body with a leading tail. The dimming events are periodic and synchronous with the stellar rotation. However, we argue it is unlikely the dimming events could be attributed to anything on the stellar surface based on the observed depths and durations. Variable obscuration by a protoplanetary disk is unlikely on the basis that the star is not actively accreting and lacks the infrared excess associated with an inner disk. Rather, we explore the possibilities that the dimming events are due to magnetospheric clouds, a transiting protoplanet surrounded by circumplanetary dust and debris, eccentric orbiting bodies undergoing periodic tidal disruption, or an extended field of dust or debris near the corotation radius.

    Shared bicycles as an important way of connecting public transport, have few literature to evaluate its effectiveness.This paper taking Beijing city as an example, make anevaluationfor the six types of travel combinations which are commonly used by the citizens. The author selects four quantitative indicators: fuel consumption, economic cost, total time spent, and CO2 emission. And two qualitative indicators: degree of comfort and convenience. The relative efficiency of quantitative indicators is obtained by data envelopment analysis (DEA) and fuzzification and then take fuzzy synthetic evaluation with qualitative indicators.It was found that the choice of shared bicycles +subway+ shared bicycles and shared bicycles has good comprehensive benefits in medium distance travel. The findings also suggest that shared bicycles +subway+ shared bicycles is the best choice in the utilitarian trips. The conclusions not only provide suggestions for the travellers to select travel modes, but also can adjust the relevant factors to increase the proportion of green travel.

    Preparing adolescents for transition into adult care and supporting their acquisition of self-health care management skills is a critical determinant of their post-transition HIV care outcomes. However, there is a scarcity of research on effective transition strategies. This study explores factors associated with adolescent preparedness for transition into adult care in Cambodia. In August 2016, a cross-sectional study was conducted among 223 adolescents living with HIV aged 15-17, randomly selected from 11 antiretroviral therapy clinics, utilizing a structured questionnaire. The level of preparedness was determined using a pre-existing scale, and adolescents were categorized as having a high- or low level of preparedness for transition. Bivariate and multivariate analyses were conducted. Of 223 adolescents, 55.2% were male, and their mean age was 15.8 years. Overall, 53.3% had a high level of preparedness for transition. As part of the transition protocol, 2.7% had completed a transfer form, 24.7% had a transition case manager, 29.6% had been counselled about the transition, and 19.7% had visited an adult ART clinic. In multivariate analysis, a higher level of preparedness for transition was independently associated with older age (AOR 2.44, 95% CI 1.34-4.46; p = 0.004), family having received social support for their health (AOR 5.32, 95% CI 1.97-14.36; p = 0.001), knowing the kind of treatment they received (ART) (AOR 12.67, 95% CI 2.91-15.19; p = 0.001), trust in friends or family for HIV treatment (AOR 7.82, 95% CI 1.13-8.89; p = 0.008), receiving counseling on transition (AOR 3.17, 95% CI 1.15-8.76; p = 0.03), having a 'Case Manager' identified to support them during the preparation process for transition (AOR 3.89, 95% CI 1.08-13.96; p = 0.04), and satisfaction with preparation process for transition in general (AOR 0.35, 95% CI 0.03-0.87; p = 0.01).

    In Finland, Posiva Oy is responsible for the final disposal of spent nuclear fuel. In the 1990's investigations have been carried out on four intended sites for final disposal. Posiva implemented Environmental Impact Assessment (EIA) on the investigation sites in 1997-1999. The results of the EIA procedure were published in the EIA report which was attached to the application filed to the Government in May 1999 for a policy decision on the construction of the final disposal facility in Olkiluoto in the municipality of Eurajoki. In December 2000, the Finnish Government made a favourable policy decision ( D ecision in Principle ) on the construction of final disposal facility for spent nuclear fuel in Olkiluoto. According to the decision, the facility is in line with the overall good of the society. According to the Government's decision the prerequisites of the policy decision had been met. The municipality of Eurajoki supported the construction of the facility in Olkiluoto and STUK, the Radiation and Nuclear Safety Authority, also approved of the advancement of the project. The positive policy decision of the Government will still need to be ratified by the Parliament. The parliamentary proceedings of the policy decision will probably start in February 2001. The policy decision will make it possible for Posiva to concentrate the future site confirmation studies in Olkiluoto, Eurajoki, and construct an underground research facility there. The excavation of the research facility in the bedrock is planned to start in a few years' time. The construction of the final disposal facility is scheduled to start after the year 2010. The transition from the site selection to the site confirmation phase in Eurajoki means a new challenge not only to Posiva's research work but also to Posiva's communication. In addition to meeting the safety criteria, Posiva's activities shall in the future also meet all the criteria specified by the surrounding society

    Magnesium is currently used for seats in many minivans and luxury cars, as well as in some high speed trains. This paper addresses concerns about the use of magnesium in manufacturing seats for public transit vehicles. This paper aimed to validate the feasibility of magnesium and/or aluminum passenger seats and determine if they met weight and cost reduction objectives currently set by the public transportation industry. An assessment of the North American bus and motor coach market was made, and passenger seat design standards were reviewed. Additionally, magnesium samples were tested to ensure industry standards for material flammability and toxic fumes emissions during exposure to intense heat. Corrosion testing and a comparison with automobile industry tests were made. A number of manufacturing case studies were conducted, including life-cycle costs and comparisons with the manufacture of traditional steel seats. It was concluded that a lighter-weight seat is both technically possible and economically viable. In terms of flammability, magnesium seats met all required industry standards, and when combined with excellent seat design, increased the safety of seat occupants projected forward during collisions. In addition, magnesium's ability to absorb vibration was seen as a substantial benefit in terms of passenger comfort. In terms of manufacturing cost alone, a magnesium-aluminum hybrid was recommended. 15 refs., 25 tabs., 24 figs.

    To examine whether individual, condition-related, and system-related characteristics are associated with state performance (high, medium, low) on the provision of transition services to children with special health care needs (CSHCN). We conducted descriptive, bivariate, and multivariable analyses of 16876 children aged 12 to 17 years by using data from the 2005-2006 National Survey of Children With Special Health Care Needs. Polytomous logistic regression was used to compare the characteristics of CSHCN residing within high-, medium-, and low-performance states, with low-performance states serving as the reference group. Compared with non-Hispanic white CSHCN, Hispanic (adjusted odds ratio [aOR]: 0.25 [95% confidence interval (CI): 0.17-0.37]) and non-Hispanic black (aOR: 0.44 [95% CI: 0.30-0.62]) CSHCN were less likely to reside in a high-performance than in a low-performance state. Compared with CSHCN who had a medical home or adequate insurance coverage, CSHCN who did not have a medical home or adequate insurance coverage were less likely to reside in a high-performance than in a low-performance state (aOR: 0.73 [95% CI: 0.57-0.95]; aOR: 0.73 [95% CI: 0.58-0.93], respectively). Key factors found to be important in a state's performance on provision of transition services to CSHCN were race/ethnicity and having a medical home and adequate insurance coverage. Efforts to support the Maternal and Child Health Bureau's integration of system-level factors in quality-improvement activities, particularly establishing a medical home and attaining and maintaining adequate insurance, are likely to help states improve their performance on provision of transition services.

    This study presents a critical evaluation of the scientific literature related to this subject, aiming to assess the policies and administrative issues regarding the prevention and magnitude of healthcare-associated infections and discuss the challenges for their prevention in Brazil. The topics discussed included historical and administrative issues, challenges imposed by the characteristics of the healthcare system and the territorial dimension, laboratorial support limitations, costs, institutional culture, professional qualification, and patient engagement. It is urgent to hold a nationwide discussion among government representatives, institutions, and healthcare workers and users to overcome these challenges.

    The association among residency program and research mentor characteristics, program director perceptions, and the publication of the primary research project for postgraduate year 2 (PGY2) graduates was assessed. Using a validated electronic survey, residency program directors (RPDs) of critical care PGY2 graduates were asked about primary research project publication success, program and research project mentor characteristics, and RPDs' perceptions surrounding project completion. All 55 RPDs surveyed responded; 44 (79%) reported being a research project mentor. PGY2 research project publications in 2011 and 2012 totaled 26 (37%) and 27 (35%), respectively. A significant relationship existed between research project publication and the number of residents in the program ( p project publication is important to their employer ( p projects versus no publications included the number of graduates in the PGY2 program (odds ratio [OR], 5.6; p project publication (OR, 10.2; p project versus no research projects was also independently associated with the RPD's perception that the employer valued research project publication (OR, 5.1; p = 0.04). A survey of RPDs of critical care PGY2 residents found that the number of PGY2 residents, the number of publications by the least experienced research mentor, and the perception that publishing the residents' research projects is important to the employer were independently associated with publication rates of residency research projects.

  1. Judges’ deadlines, deadlines for public administration and associations

    Directory of Open Access Journals (Sweden)

    Daniel Chabanol

    2015-01-01

    Full Text Available In the theory on the activity of the judge in disputes related to exceeding powers, one fundamental principle demands that this activity is ‘beyond time’: the judge examines some past events and objectively seeks whether the administrative act being disputed has been undertaken according to the norms which should have been applied, which the judge, if necessary, identifies retroactively (emphasising that s/he does not create them. The claim of the illegality of the administrative act leads to its retroactive revocation and to the reconstruction of what should have been in administrative activity. This theory has not however survived in relation to the principle of reality. The inevitable passing of time, both in public administration and in society resist the ‘beyond time’ aspect of judge activity. This resistance is founded on social expectations and on the principle of legal security. The judge in cases of exceeding powers also responds to the demands on the one hand to become more familiar with the methods of the judge in full adjudication disputes, and on the other hand, to abandon to a certain extent the retroactivity of its intervention. This raises the following question of: is the judge in cases of legality still some kind of ‘general inspector’ of public power or does the judge become a means of appeasing the conflict which occurs in life in general? Similarly, a judge in a dispute on exceeding powers responding to a concrete social demand accepting that revocation, even retroactive, of an administrative act is not always sufficient to reinstate the principle of a country that adheres to the law. That is why, as a deciding criterion in judicial functioning, the concept of the duration of proceedings has been introduced. So, besides the customary damages and the result of consequences caused by the unreasonable duration of proceedings, it has been concluded that new attention be paid to the duration of proceedings. This is

    Full Text Available Introduction. Paraneoplastic encephalomyelitis (PEM and subacute sensory neuronopathy (SSN are remote effects of cancer, usually associated with small-cell lung carcinoma and positive anti-Hu antibody. We describe the rare association of bladder transitional cell carcinoma (TCC with anti-Hu antibody positivity resulting in this paraneoplastic neurological syndrome. Patient. A 76-year-old female presented with bilateral muscle weakness and paraesthesia of the upper and lower limbs in a length-dependent “glove and stocking” distribution. Central nervous system symptoms included cognitive problems, personality change, and truncal ataxia. Case notes and the literature were reviewed. Result. Autoantibody screening was positive for anti-Hu antibody (recently renamed antineuronal nuclear antibody 1, ANNA-1. The diagnosis of PEM and SSN was supported by MRI and lumbar puncture results. A superficial bladder TCC was demonstrated on CT and subsequently confirmed on histology. No other primary neoplasm was found on full-body imaging. The neurological symptoms were considered to be an antibody-mediated paraneoplastic neurological syndrome and improved after resection of the tumour. Discussion. The association of anti-Hu positive paraneoplastic neurological syndrome and TCC has not been described in the literature previously. We emphasize the need for detailed clinical examination and the importance of a multidisciplinary thought process and encourage further awareness of this rare association.

    To examine the association of health literacy with the number and type of transitional care needs (TCN) among patients being discharged to home. A cross-sectional analysis of patients admitted to an academic medical center. Nurses administered the Brief Health Literacy Screen and documented TCNs along 10 domains: caregiver support, transportation, healthcare utilization, high-risk medical comorbidities, medication management, medical devices, functional status, mental health comorbidities, communication, and financial resources. Among the 384 patients analyzed, 113 (29%) had inadequate health literacy. Patients with inadequate health literacy had needs in more TCN domains (mean = 5.29 vs 4.36; P literacy were significantly more likely to have TCNs in 7 out of the 10 domains. In multivariate analyses, inadequate health literacy remained significantly associated with inadequate caregiver support (odds ratio [OR], 2.61; 95% confidence interval [CI], 1.37-4.99) and transportation barriers (OR, 1.69; 95% CI, 1.04-2.76). Among hospitalized patients, inadequate health literacy is prevalent and independently associated with other needs that place patients at a higher risk of adverse outcomes, such as hospital readmission. Screening for inadequate health literacy and associated needs may enable hospitals to address these barriers and improve postdischarge outcomes. © 2017 Society of Hospital Medicine

  4. The Media Protest of Neighbouring Associations, Promoter of Citizen Democratic Culture during Transition in Southern Spain

    Full Text Available In the current context of placing value on the neighbouring movement within the Spanish democratic Transition, we set out to confirm that the press actively participates in the growing conjunction of neighbouring issues with political content and contributes to the idea that this movement becomes a parameter of the democratic culture for the citizen during Transition. Since the conflict is newsworthy, we conduct a micro-social study of the neighbouring protest in the newspaper El Correo de Andalucía, published in the southern Spanish city of Seville. Through analysis of content, we study the informative flow and the repertoire of protest following a typology that distinguishes four formats (demonstrations, strikes, speeches and associations divided into two levels of conflict. The analysis sample consists of 33 texts published between November 1975 (Franco’s death and the accession to the throne of Juan Carlos I and June 1977 (the first democratic general elections. The main conclusion reveals that the newspaper becomes a platform that gives visibility to the neighbouring movement, normalising behaviours and procedure rules through the protest.

  5. TRANSITION METAL TRANSPORT IN PLANTS AND ASSOCIATED ENDOSYMBIONTS: ARBUSCULAR MYCORRHIZAL FUNGI AND RHIZOBIA

    Directory of Open Access Journals (Sweden)

    Manuel González-Guerrero

    2016-07-01

    Full Text Available Transition metals such as iron, copper, zinc, or molybdenum, are essential nutrients for plants. These elements are involved in almost every biological process, including photosynthesis, tolerance to biotic and abiotic stress, or symbiotic nitrogen fixation. However, plants often grow in soils with limiting metallic oligonutrient bioavailability. Consequently, to ensure the proper metal levels, plants have developed a complex metal uptake and distribution system, that not only involves the plant itself, but also its associated microorganisms. These microorganisms can simply increase metal solubility in soils and making them more accessible to the host plant, as well as induce the plant metal deficiency response, or deliver directly transition elements to cortical cells. Other, instead of providing metals can act as metal sinks, such as endosymbiotic rhizobia in legume nodules that requires relatively large amounts to carry out nitrogen fixation. In this review, we propose to do an overview of metal transport mechanisms in the plant-microbe system, emphasizing the role of arbuscular mycorrhizal fungi and endosymbiotic rhizobia.

    This report has been prepared in the hope that it will calculate, apparently for the first time, the non-radiological risks associated with the use of nuclear fuels. The specific risks identified and evaluated in this work should be balanced against the benefits resulting from the use of nuclear fuels or against the risks inherent in other fuels. Due to lack of sufficient data in certain areas the results obtained are subject to a large degree of uncertainty and therefore the results indicate an order of magnitude rather than exact values of hazard. The total hazard can be expressed as 6.0 ± 4.8 x 10 -3 fatalities and 4.8 ± 0.7 x l0 -2 injuries per 1 GWy of electricity produced

    A new kind of oscillatory steady state is discovered in observation of potential with a heavy ion beam probe in Compact Helical System Heliotron/Torsatron. Bulk plasma parameters, such as electron temperature and density profile, change being synchronized with the pulsation of potential. The phenomenon can be regarded as successive transitions between two bifurcative states of the plasma. The pulsation can be self-sustained and create a dynamic steady state in low density plasma with electron cyclotron heating. The cause of phenomenon is associated with the bifurcation nature of radial electric field, that is inherent with toroidal helical plasmas. This paper presents two examples of the phenomenon in different density regimes. Dependence of pulsation characteristics on several parameters is described. The bifurcation property predicted by a neoclassical theory is presented for comparison with the experimental observations. (author)

    Climate change is today's greatest public health threat. 1 As the nation's leading voice in public health, the American Public Health Association (APHA) has demonstrated an enduring commitment to climate change as a health issue. As far back as the mid-1920s, AJPH reported on the health impacts of climate change. 2-4 Shaping the development of future organizational efforts, APHA members created the organization's first policy statement on climate change in 1995 (updated in 2007 and 2015). APHA continued to bring attention to climate change and public health, making it the theme of National Public Health Week 2008. Since then, evidence of climate change's causes and effects has mounted, but politicization of the issue and low prioritization by the public has made progress toward mitigation and adaptation slow.

    The SFTE project aims to establish a broad partnership between public and private entities to stimulate the economy and deliver between euros 180 bn and euros 420 bn of investment in Europe over 10 years for the benefit of medium-sized projects (in the order of euros 1 m) that are necessary for the energy transition. It will enable EU banks to finance the energy renovation of public buildings under excellent - cheap and long-term - conditions. A feasibility study has been conducted by the AFTER association with an exemplary consortium of public and private stakeholders in France: local authorities, industry players, banks/financial institutions, NGOs, Plan Batiment Durable. Many European institutions have expressed their interest in the initiative. Now the implementation of the SFTE project requires a commitment from European and national public authorities. Such a proactive real-estate policy would significantly contribute to economic recovery, cut costs, CO_2 emissions and the external deficit and improve energy independence, and could quickly create jobs. This document is the English version of the synthesis report of the SFTE project feasibility study. Two notes are attached to the document: one is a note to decision makers on the adaptation of the project to the euro 315 bn investment plan proposed by Jean-Claude Juncker, and the other is a technical note to decision makers

    2016-07-01

    The objective of this study was to characterize the relationship between rumination and subclinical ketosis (SCK) in transition dairy cows. A study was conducted on 4 commercial dairy farms in eastern Ontario, Canada. A total of 339 Holstein dairy cows (107 primiparous and 232 multiparous) were monitored for rumination activity and SCK from 14 d before calving until 28 d after calving. Rumination was recorded daily using an automated monitoring system. A blood sample was taken from the coccygeal vein of each cow for measurement of β-hydroxybutyrate (BHB) once weekly throughout the 6-wk observation period. Cows with BHB ≥1.2mmol/L in any of the 4 postpartum samples were considered to have SCK. Cases of retained placenta, metritis, milk fever, or mastitis during the study period were also recorded. Cows were categorized into 1 of 4 groups: healthy cows (HLT) that had no SCK or any other recorded health problem (n=139); cows treated for at least one health issue other than SCK (HLT+; n=50); cows with SCK (hyperketonemia; HYK) with no other health problems during transition (n=97); or cows (HYK+) that had SCK and one or more other health problems (n=53). Daily rumination time was summarized by week and comparisons were made between HLT and HYK and HYK+. From 2 wk before calving (wk -2) to 4 wk after calving (wk +4), there was no difference in rumination time (409±9.8min/d) among HLT, HYK, and HYK+ cows in their first lactation. Multiparous cows in HLT spent an average of 459±11.3min/d ruminating from wk -2 to wk +4. Multiparous HYK cows ruminated 25±12.8min/d less than HLT cows, whereas HYK+ cows ruminated 44±15.6min/d less than HLT cows. The largest differences in rumination time between HLT and HYK+ cows were seen during wk -1, +1, and +2, when HYK+ cows ruminated 48±17.2, 73±16.0, and 65±19.4min/d less than HLT cows, respectively. In multiparous cows, increased odds of HYK were associated with greater milk yield in the previous lactation, greater loss of

    The objective of this study was to characterize the association of lying behavior and subclinical ketosis (SCK) in transition dairy cows. A total of 339 dairy cows (107 primiparous and 232 multiparous) on 4 commercial dairy farms were monitored for lying behavior and SCK from 14d before calving until 28 d after calving. Lying time, frequency of lying bouts, and average lying bout length were measured using automated data loggers 24h/d. Cows were tested for SCK 1×/wk by taking a blood sample and analyzing for β-hydroxybutyrate; cows with β-hydroxybutyrate ≥1.2mmol/L postpartum were considered to have SCK. Cases of retained placenta, metritis, milk fever, or mastitis during the study period were recorded and cows were categorized into 1 of 4 groups: healthy (HLT) cows had no SCK or any other health problem (n=139); cows treated for at least 1 health issue other than SCK (n=50); SCK (HYK) cows with no other health problems during transition (n=97); or subclinically ketotic plus (HYK+) cows that had SCK and 1 or more other health problems (n=53). Daily lying time was summarized by week and comparisons were made between HLT, HYK, and HYK+, respectively. We found no difference among health categories in lying time, bout frequency, or bout length fromwk -2 towk +4 relative to calving for first-lactation cows. Differences in lying time for multiparous cows were seen inwk +1, when HYK+ cows spent 92±24.0 min/d more time lying down than HLT cows, and duringwk +3 and +4 when HYK cows spent 44±16.7 and 41±18.9 min/d, respectively, more time lying down than HLT cows. Increased odds of HYK+ were found to be associated with higher parity, longer dry period, and greater stall stocking density inwk -1 and longer lying time duringwk +1. When comparing HYK to HLT cows, the same variables were associated with odds of SCK; however, lying time was not retained in the final model. These results suggest that monitoring lying time may contribute to identifying multiparous cows

    The traditionally semi-nomadic Bedouin Arabs in Israel are undergoing urbanisation with concurrent lifestyle changes, including a shift to using unfortified white-flour bread instead of wholewheat bread as the main dietary staple. We explored associations between the transition from wholewheat to white-flour bread and (1) lifestyle factors, (2) overall diet quality, and (3) health status. We conducted a nutrition survey among 451 Bedouin adults, using a modified 24 h recall questionnaire. Bread intake accounted for 32.7 % of the total energy intake. Those consuming predominantly white bread (PWB) (n 327) were more likely to be urban (OR 2.79; 95 % CI 1.70, 4.58), eating store-bought rather than homemade bread (OR 8.18; 95 % CI 4.34, 15.41) and currently dieting (OR 4.67; 95 % CI 1.28, 17.11) than those consuming predominantly wholewheat bread (PWWB) (n 124). PWB consumption was associated with a lower intake of dietary fibre (23.3 (se 0.6) v. 41.8 (se 1.0) g/d; P consumption (P or = 40 years, PWB consumption was associated with a 9.85-fold risk (95 % CI 2.64, 36.71; P = 0.001) of having one or more chronic conditions, as compared with PWWB consumption, after controlling for other risk factors. White bread intake was associated with a less traditional lifestyle and poorer diet quality, and may constitute a useful marker for at-risk subgroups to target for nutritional interventions.

    Guidelines recommend a switch from intravenous to oral antibiotics once patients who are hospitalized with pneumonia achieve clinical stability. However, little evidence guides the selection of an oral antibiotic for patients with health care-associated pneumonia, especially where no microbiological diagnosis is made. To compare outcomes between patients who were transitioned to broad- versus narrow-spectrum oral antibiotics after initially receiving broad-spectrum intravenous antibiotic coverage. We performed a secondary analysis of an existing database of adults with community-onset pneumonia admitted to seven Utah hospitals. We identified 220 inpatients with microbiology-negative health care-associated pneumonia from 2010 to 2012. After excluding inpatient deaths and treatment failures, 173 patients remained in which broad-spectrum intravenous antibiotics were transitioned to an oral regimen. We classified oral regimens as broad-spectrum (fluoroquinolone) versus narrow-spectrum (usually a β-lactam). We compared demographic and clinical characteristics between groups. Using a multivariable regression model, we adjusted outcomes by severity (electronically calculated CURB-65), comorbidity (Charlson Index), time to clinical stability, and length of intravenous therapy. Age, severity, comorbidity, length of intravenous therapy, and clinical response were similar between the two groups. Observed 30-day readmission (11.9 vs. 21.4%; P = 0.26) and 30-day all-cause mortality (2.3 vs. 5.3%; P = 0.68) were also similar between the narrow and broad oral antibiotic groups. In multivariable analysis, we found no statistically significant differences for adjusted odds of 30-day readmission (adjusted odds ratio, 0.56; 95% confidence interval, 0.06-5.2; P = 0.61) or 30-day all-cause mortality (adjusted odds ratio, 0.55; 95% confidence interval, 0.19-1.6; P = 0.26) between narrow and broad oral antibiotic groups. On the basis of analysis of a limited number of patients

    To evaluated the differences in knowledge, adherence, attitudes, and beliefs about medicine in adolescents with inflammatory bowel disease (IBD) attending transition clinics. We prospectively enrolled patients from July 2012 to June 2013. All adolescents who attended a tertiary-centre-based dedicated IBD transition clinic were invited to participate. Adolescent controls were recruited from university-affiliated gastroenterology offices. Participants completed questionnaires about their disease and reported adherence to prescribed therapy. Beliefs in Medicine Questionnaire was used to evaluate patients' attitudes and beliefs. Beliefs of medication overuse, harm, necessity and concerns were rated on a Likert scale. Based on necessity and concern ratings, attitudes were then characterized as accepting, ambivalent, skeptical and indifferent. One hundred and twelve adolescents were included and 59 attended transition clinics. Self-reported adherence rates were poor, with only 67.4% and 56.8% of patients on any IBD medication were adherent in the transition and control groups, respectively. Adolescents in the transition cohort held significantly stronger beliefs that medications were necessary ( P = 0.0035). Approximately 20% of adolescents in both cohorts had accepting attitudes toward their prescribed medicine. However, compared to the control group, adolescents in the transition cohort were less skeptical of (6.8% vs 20.8%) and more ambivalent (61% vs 34%) (OR = 0.15; 95%CI: 0.03-0.75; P = 0.02) to treatment. Attendance at dedicated transition clinics was associated with differences in attitudes in adolescents with IBD.

    To determine whether an association exists between the publication of journal articles before and during paediatrics residency. A retrospective search of PubMed was conducted for publications by all 567 Canadian paediatricians certified between 2009 and 2012, inclusive. Paediatricians were separated into groups based on the number of articles published preresidency (0 or ≥1) and during residency (0 or ≥1). The methodology was validated using a group of local paediatricians who were contacted to verify whether their publications were identified accurately. A total of 160 of 567 (28%) certified paediatricians had preresidency publications; of these, 93 (58%) subsequently published during their residency period. Among the remaining 407 (72%) paediatricians without preresidency publications, 129 (32%) published during residency. The association between publication before and during paediatric residency was statistically significant (OR 2.98 [95% CI 2.04 to 4.36]; Ppublication status with 87% and 90% accuracy, respectively. Individuals with previous publications were more likely to publish as residents; however, 42% of individuals with pre-residency publications did not publish as residents. Residency selection committees may find these data helpful in assessing the publication potential of their applicants. In addition, this information may assist in building more targeted and individualized research curricula within residency programs.

    The Acute Psychological Trauma (APT) Study was a collaboration between an acute care hospital, a specialized multidisciplinary program designed to meet the mental health needs of injured workers, and a large urban public transit system. The overall purpose was to evaluate a Best Practices Intervention (BPI) for employees affected by acute psychological trauma compared to a Treatment as Usual (TAU) group. The specific purpose is to discuss facilitators and barriers that were recognized in implementing and carrying out mental health research in a workplace setting. Over the course of the APT study, a joint implementation committee was responsible for day-to-day study operations and made regular observations on the facilitators and barriers that arose throughout the study. The facilitators to this study included the longstanding relationships among the partners, increased recognition for the need of mental health research in the workplace, and the existence of a community advisory committee. The significant barriers to doing this study of mental health research in the workplace included differences in organizational culture, inconsistent union support, co-interventions, and stigma. Researchers and funding agencies need to be flexible and provide additional resources in order to overcome the barriers that can exist doing workplace mental health research.

Though research has demonstrated the benefits of helmet use in preventing serious and fatal injuries in the event of a crash, helmet use has remained relatively stable in the United States, where the most recent national estimates show a 64% use rate. Use rates have been markedly lower among those states that do not have a universal helmet law for all riders. In 2012, the state of Michigan repealed its longstanding mandatory helmet use law. In order to gain insights as to the effects of this legislative change, a study was conducted to examine short-term changes in helmet use and identify factors associated with use rates. A statewide direct observation survey was conducted 1 year after the transition from a universal helmet law to a partial helmet law. A random parameters logistic regression model was estimated to identify motorcyclist, roadway, and environmental characteristics associated with helmet use. This modeling framework accounts for both intravehicle correlation (between riders and passengers on the same motorcycle) as well as unobserved heterogeneity across riders due to important unobserved factors. Helmet use was shown to vary across demographic segments of the motorcyclist population. Use rates were higher among Caucasian riders, as well as among those age 60 and above. No significant difference was observed between male and female riders. Use was also found to vary geographically, temporally, and with respect to various environmental characteristics. Geographically, helmet use rates tended to be correlated with historical restraint use trends, which may be reflective of riding environment and general differences in the riding population. To this end, rates were also highly variable based upon the type of motorcycle and whether the motorcyclist was wearing high-visibility gear. The study results demonstrate

    Recent research on the patterns of self-harm around public holidays is lacking. This study used national data to examine the patterns of hospital-treated self-harm during public holidays, and to examine associated factors. Data on self-harm presentations to all emergency departments were obtained from the National Self-Harm Registry Ireland. The association between self-harm presentations and public holidays was examined using univariate and multivariate Poisson regression analyses. A total of 104,371 presentations of self-harm were recorded between 2007 and 2015. The mean number of self-harm presentations was 32 on public holidays. St. Patrick's Day had the highest number of presentations compared to all other public holidays, with a daily mean of 44 presentations. Across all years, self-harm presentations during public holidays had a 24% increased risk of involving alcohol consumption compared to all other days and this effect was most pronounced during the Christmas period. The association with alcohol remained significant at a multivariate level. Presentations on public holidays were more likely to attend out of normal working hours. An increase in male presentations involving self-cutting was observed on public holidays and there was an over-representation of males presenting for the first time. It is likely that extent of alcohol involvement in self-harm presentations reported here is an underestimate, as it was dependent on the information being recorded by the attending clinician. Public holidays are associated with an elevated number of self-harm presentations to hospital, with presentations to hospital involving alcohol significantly increased on these days. Hospital resources should be targeted to address increases during public holidays, including during out-of-hours. Involvement of alcohol may delay delivery of care to these patients in emergency settings. Copyright © 2017 Elsevier B.V. All rights reserved.

    Nearly 30 people have drowned in dam-related incidents over the last 10 years in Canada. The Canadian public is now calling for improved safety guidelines. Public interaction with dams is increasing as a result of interest in extreme sports and perceived rights of access. However, many members of the public are not aware of the dangers posed by dams. This workshop provided a forum to discuss proposals for a draft publication of the Canadian Dam Association (CDA) guidelines for public safety and security around dams. Issues related to current legislation and liability were discussed. Methods of increasing public awareness of the hazards posed by dams included increased signage in dam locations, the use of audible and visual alert systems, and the use of booms and buoys. The responsibilities of dam owners in ensuring the safety of dams were also discussed. The conference featured 5 presentations, of which 2 have been catalogued separately for inclusion in this database. tabs., figs.

    To identify and analyze the factors associated with the decision of migrants suffering violence while in transit through Mexico, to continue on their trip or turn back. Cross-sectional study combining quantitative and qualitative analyses. Socio-demographic and health characteristics, as well as types of violence and factors associated with the decision to continue on the trip, were explored for 862 migrants. 35 migrants were interviewed to explore their perceptions of migration, socioeconomic and political situations in their countries of origin, risks, violence experienced, and the decision to continue on their trip. Of the 862 migrants, 21.1% experienced violence during their transit through Mexico towards the USA. Of these, 88.5% decided to continue on their journey. This decision was positively associated with age (OR = 1.075, p transit and the presence of health problems. The decision to continue the journey to the United States was related to structural factors in the countries of origin, rather than risks in transit. It is necessary to implement mechanisms to promote and protect the human rights of migrants during their whole journey (origin, transit and destination).

    To review guidance from professional medical associations to physicians on the Sunshine Act, with a focus on industry support for medical publications. Using 'Sunshine Act' as a search term, we searched PubMed (dates February 2013 to November 2014) and the 'grey literature' using Google and Google Scholar. Online information was extracted from websites of pre-identified professional medical associations. Some professional medical associations have published peer-reviewed recommendations, position statements or general advice on their websites and in journals around the Sunshine Act. Associations also provided broad online educational resources for physicians. There was universal agreement between peer-reviewed publications, including guidelines, for the need for full transparency and disclosure of industry support. Surveys by some professional associations showed variance in opinion on the forecasted impact of the Sunshine Act on physician-industry relationships. There was scarce information specifically related to reporting requirements for industry-supported medical publications. There is a shortage of information for physicians from professional associations regarding the Sunshine Act and support for medical publications. Due to the lack of clear guidance regarding support for publications, there are presently varying interpretations of the Sunshine Act. The literature debates the potential impact of the Sunshine Act and expresses some concerns that physician-enabled innovation in drug development may be hindered.

    Gene Wiki Plus (GeneWiki+) and the Online Mendelian Inheritance in Man (OMIM) are publicly available resources for sharing information about disease-gene and gene-SNP associations in humans. While immensely useful to the scientific community, both resources are manually curated, thereby making the data entry and publication process time-consuming, and to some degree, error-prone. To this end, this study investigates Semantic Web technologies to validate existing and potentially discover new genotype-phenotype associations in GWP and OMIM. In particular, we demonstrate the applicability of SPARQL queries for identifying associations not explicitly stated for commonly occurring chronic diseases in GWP and OMIM, and report our preliminary findings for coverage, completeness, and validity of the associations. Our results highlight the benefits of Semantic Web querying technology to validate existing disease-gene associations as well as identify novel associations although further evaluation and analysis is required before such information can be applied and used effectively.

    Learning theory proposes that drug seeking is a synthesis of multiple controllers. Whereas goal-directed drug seeking is determined by the anticipated incentive value of the drug, habitual drug seeking is elicited by stimuli that have formed a direct association with the response. Moreover, drug-paired stimuli can transfer control over separately trained drug seeking responses by retrieving an expectation of the drug's identity (specific transfer) or incentive value (general transfer). This review covers outcome devaluation and transfer of stimulus-control procedures in humans and animals, which isolate the differential governance of drug seeking by these four controllers following various degrees of contingent and noncontingent drug exposure. The neural mechanisms underpinning these four controllers are also reviewed. These studies suggest that although initial drug seeking is goal-directed, chronic drug exposure confers a progressive loss of control over action selection by specific outcome representations (impaired outcome devaluation and specific transfer), and a concomitant increase in control over action selection by antecedent stimuli (enhanced habit and general transfer). The prefrontal cortex and mediodorsal thalamus may play a role in this drug-induced transition to behavioral autonomy. © 2012 New York Academy of Sciences.

    Adolescence is a transition stage between childhood and adulthood and is an important phase for the acquisition of future lifestyles, including the practice of physical activity (PA). The prevalence of sedentary lifestyle in adolescents is often high, creating the need for studies addressing the practice of PA and its associated factors for a better understanding of the phenomenon and possible interventions that would encourage positive changes. Cross-sectional study of a representative sample of students aged 14-18 years enrolled in both public and private schools of a large Brazilian city to determine the level of physical activity (PA) and its associated factors. Sedentary lifestyle was measured by applying the International Physical Activity Questionnaire. The independent variables were gender, age, race, tobacco use and alcohol consumption in the past 30 days, socioeconomic status, body mass index, waist circumference and blood pressure. The crude prevalence ratio was used as a measure of association and was estimated from a Poisson regression. The sample consisted of 862 adolescents with a mean age of 15.4 ± 1.1 years. Females were predominant (52.8%), and the age between 14 and 15 years was the most frequent (52.2%). The majority of the group reported themselves as Caucasians (51.2%), belonging to socioeconomic class C (52.5%) and were attending to public schools (69.1%). The prevalence of sedentary lifestyle was 66.8% (95% confidence interval [CI]: 63.5-69.9), where values of 65.4% and 69.9% were observed among students from public and private schools, respectively (p = 0.196). Sedentary lifestyle was more frequent in females (78.0% vs 54.3%; p sedentary lifestyle was female gender both in public and private schools and the only independent variable related to sedentarism was also female gender. The prevalence of sedentary lifestyle was extremely high in the population of adolescents studied both in public and private schools. Female sex was

    The Republic of Vanuatu, like many developing nations, is undergoing a rapid health transition. Our previous study identified several behavioral risk factors for the rising prevalence of obesity. Unexpectedly, daily time spent using television and radio was revealed as a protective factor for obesity in 2007. In this study, we sought to explore associations between ownership of consumer electronics (CE) and measures of adiposity in Vanuatu in 2011. We surveyed 873 adults from five islands varying in level of economic development. Height, weight, and waist circumferences; triceps, subscapular, and suprailiac skinfolds; and percent body fat by bioelectrical impedance were measured. Ownership of eight types of CE, diet through 24-h dietary recall and leisure-time activity patterns were assessed using a questionnaire. Participants from more developed islands owned more types of CE, and revealed higher measures of adiposity on average as well as higher prevalence of obesity/central obesity. When controlling for demographic factors, and dietary and activity patterns, increased measures of adiposity and risk for obesity/central obesity were associated with ownership of cellphones, music players, televisions, video players, microwaves, and/or refrigerators. Positive correlations between CE ownership and measures of adiposity were mainly observed among men on the two most developed islands. The results of this study indicate a possible role of CE use in the rising prevalence of obesity and the shift to a sedentary lifestyle in Vanuatu and many other modernizing regions, where prevention efforts including education on healthy use of CE are imperative. © 2016 Wiley Periodicals, Inc.

    Full Text Available BACKGROUND: Majority of bladder cancer deaths are caused due to transitional cell carcinoma (TCC which is the most prevalent and chemoresistant malignancy of urinary bladder. Therefore, we analyzed the role of Sperm associated antigen 9 (SPAG9 in bladder TCC. METHODOLOGY AND FINDINGS: We examined SPAG9 expression and humoral response in 125 bladder TCC patients. Four bladder cancer cell lines were assessed for SPAG9 expression. In addition, we investigated the effect of SPAG9 ablation on cellular proliferation, cell cycle, migration and invasion in UM-UC-3 bladder cancer cells by employing gene silencing approach. Our SPAG9 gene and protein expression analysis revealed SPAG9 expression in 81% of bladder TCC tissue specimens. High SPAG9 expression (>60% SPAG9 positive cells was found to be significantly associated with superficial non-muscle invasive stage (P = 0.042 and low grade tumors (P = 0.002 suggesting SPAG9 putative role in early spread and tumorigenesis. Humoral response against SPAG9 was observed in 95% of patients found positive for SPAG9 expression. All four bladder cancer cell lines revealed SPAG9 expression. In addition, SPAG9 gene silencing in UM-UC-3 cells resulted in induction of G0-G1 arrest characterized by up-regulation of p16 and p21 and consequent down-regulation of cyclin E, cyclin D and cyclin B, CDK4 and CDK1. Further, SPAG9 gene silencing also resulted in reduction in cellular growth, and migration and invasion ability of cancer cells in vitro. CONCLUSIONS: Collectively, our data in clinical specimens indicated that SPAG9 is potential biomarker and therapeutic target for bladder TCC.

    An Enhanced Intervening Opportunities Model (EIOM) is developed for Public Transit (PT). This is a distribution supply dependent model, with single constraints on trip production for work trips during morning peak hours (6:00 a.m.-9:00 a.m.) within the Island of Montreal, Canada. Different data sets, including the 2008 Origin-Destination (OD) survey of the Greater Montreal Area, the 2006 Census of Canada, GTFS network data, along with the geographical data of the study area, are used. EIOM is a nonlinear model composed of socio-demographics, PT supply data and work location attributes. An enhanced destination ranking procedure is used to calculate the number of spatially cumulative opportunities, the basic variable of EIOM. For comparison, a Basic Intervening Opportunities Model (BIOM) is developed by using the basic destination ranking procedure. The main difference between EIOM and BIOM is in the destination ranking procedure: EIOM considers the maximization of a utility function composed of PT Level Of Service and number of opportunities at the destination, along with the OD trip duration, whereas BIOM is based on a destination ranking derived only from OD trip durations. Analysis confirmed that EIOM is more accurate than BIOM. This study presents a new tool for PT analysts, planners and policy makers to study the potential changes in PT trip patterns due to changes in socio-demographic characteristics, PT supply, and other factors. Also it opens new opportunities for the development of more accurate PT demand models with new emergent data such as smart card validations.

    Abstract Cyanobacteria belonging to the genus Nostoc comprise free-living strains and also facultative plant symbionts. Symbiotic strains can enter into symbiosis with taxonomically diverse range of host plants. Little is known about genomic changes associated with evolutionary transition of Nostoc from free-living to plant symbiont. Here, we compared the genomes derived from 11 symbiotic Nostoc strains isolated from different host plants and infer phylogenetic relationships between strains. Phylogenetic reconstructions of 89 Nostocales showed that symbiotic Nostoc strains with a broad host range, entering epiphytic and intracellular or extracellular endophytic interactions, form a monophyletic clade indicating a common evolutionary history. A polyphyletic origin was found for Nostoc strains which enter only extracellular symbioses, and inference of transfer events implied that this trait was likely acquired several times in the evolution of the Nostocales. Symbiotic Nostoc strains showed enriched functions in transport and metabolism of organic sulfur, chemotaxis and motility, as well as the uptake of phosphate, branched-chain amino acids, and ammonium. The genomes of the intracellular clade differ from that of other Nostoc strains, with a gain/enrichment of genes encoding proteins to generate l-methionine from sulfite and pathways for the degradation of the plant metabolites vanillin and vanillate, and of the macromolecule xylan present in plant cell walls. These compounds could function as C-sources for members of the intracellular clade. Molecular clock analysis indicated that the intracellular clade emerged ca. 600 Ma, suggesting that intracellular Nostoc symbioses predate the origin of land plants and the emergence of their extant hosts.

    Genes necessary to enable nematode parasitic life after free-living larval life are of substantial interest to understand parasitism. We investigated transcriptional changes during transition to parasitism in the bovine lungworm Dictyocaulus viviparus, one of the most important parasites in cattle farming due to substantial economic losses. Upregulated transcripts in either free-living, developmentally arrested L3 or parasitic immature L5 were identified by suppression subtractive hybridization (SSH) followed by differential screening and subsequent virtual Northern blot verification. From 400 sequenced clones of parasitic L5, 372 (93.0%) upregulated high quality ESTs were obtained clustering into 30 contigs and 38 singletons. Most conceptual translated peptides were SCP/TAPS "family" members also known as pathogenesis-related protein (PRP) superfamily (28.5% of total ESTs), cysteine proteases (24.5%), and H-gal-GP orthologues (9.9%). These proteins are predicted to play key roles in fundamental biological processes such as nutrition and development but also parasite-host interactions and immune defense mechanisms. Increased energy requirement of the rapidly developing L5 lungworm stage was obvious in a proportion of 12.2% upregulated ESTs being components of the respiratory chain. From the developmentally arrested L3 stage sequencing of 200 clones resulted in 195 high quality ESTs (97.0%) clustering into 7 contigs and 3 singletons only. Besides a hypothetical protein (70.1% of total ESTs) most transcripts encoded the cleavage stimulation factor subunit 2 (17.5%), which is a component of the poly(A(+)) machinery and found to be involved in gene silencing. Obtained data provide the basis for future fundamental research into genes associated with parasitic lifestyle but also applied research like vaccine and/or drug development.

    2007-09-01

    The partial molar volume (PMV) change associated with the pressure-induced structural transition of ubiquitin is analyzed by the three-dimensional reference interaction site model (3D-RISM) theory of molecular solvation. The theory predicts that the PMV decreases upon the structural transition, which is consistent with the experimental observation. The volume decomposition analysis demonstrates that the PMV reduction is primarily caused by the decrease in the volume of structural voids in the protein, which is partially canceled by the volume expansion due to the hydration effects. It is found from further analysis that the PMV reduction is ascribed substantially to the penetration of water molecules into a specific part of the protein. Based on the thermodynamic relation, this result implies that the water penetration causes the pressure-induced structural transition. It supports the water penetration model of pressure denaturation of proteins proposed earlier.

    Recent studies on transit service through an equity lens have captured broad trends from the literature and national-level data or analyzed disaggregate data at the local level. This study integrates these methods by employing a geostatistical analysis of new transit access and income data compilations from the Environmental Protection Agency. By using a national data set, this study demonstrates a method for income-based transit equity analysis and provides results spanning nine large auto-oriented cities in the US. Results demonstrate variability among cities' transit services to low-income populations, with differing results when viewed at the regional and local levels. Regional-level analysis of transit service hides significant variation through spatial averaging, whereas the new data employed in this study demonstrates a block-group scale equity analysis that can be used on a national-scale data set. The methods used can be adapted for evaluation of transit and other modes' transportation service in areas to evaluate equity at the regional level and at the neighborhood scale while controlling for spatial autocorrelation. Transit service equity planning can be enhanced by employing local Moran's I to improve local analysis.

    Despite the fact that public and private nursing schools have contributed significantly to the Thai health system, it is not clear whether and to what extent there was difference in job preferences between types of training institutions. This study aimed to examine attitudes towards rural practice, intention to work in public service after graduation, and factors affecting workplace selection among nursing students in both public and private institutions. A descriptive comparative cross-sectional survey was conducted among 3349 students from 36 nursing schools (26 public and 10 private) during February-March 2012, using a questionnaire to assess the association between training institution characteristics and students' attitudes, job choices, and intention to work in the public sector upon graduation. Comparisons between school types were done using ANOVA, and Bonferroni-adjusted multiple comparisons tests. Principal component analysis (PCA) was used to construct a composite rural attitude index ( 14 questions). Cronbach's alpha was used to examine the internal consistency of the scales, and ANOVA was then used to determine the differences. These relationships were further investigated through multiple regression. A higher proportion of public nursing students (86.4% from the Ministry of Public Health and 74.1% from the Ministry of Education) preferred working in the public sector, compared to 32.4% of students from the private sector ( p  = public nursing schools were less motivated by financial incentive regarding workplace choices relative to students trained by private institutions. To increase nursing workforce in the public sector, the following policy options should be promoted: 1) recruiting more students with a rural upbringing, 2) nurturing good attitudes towards working in rural areas through appropriate training at schools, 3) providing government scholarships for private students in exchange for compulsory work in rural areas, and 4) providing a

    Aims To examine the transitions in smoking status among nondaily smokers who transitioned to daily or former smokers or remained as nondaily smokers over a 12-month period. We analyzed factors associated with these transitions, including the use of cigars and smokeless tobacco (SLT). Design Secondary data analyses using pooled data from the 2003, 2006/07 and 2010/11 Tobacco Use Supplements to the Current Population Survey (TUS-CPS). Setting USA Participants Self-respondents aged 18+ who have smoked for more than 5 years and were nondaily smokers 12 months before the interview (n = 13,673 or 14.5% of current smokers). Measurements Multinomial logistic regression model to determine the correlates of nondaily-to-daily, stable nondaily, and nondaily-to-former smoking transitions among nondaily smokers at baseline. The model controlled for socio-demographic factors and the use of cigars and SLT. Findings 2.6% of adults in our sample were nondaily smokers at baseline. Among these, 69.7% remained nondaily smokers (stable nondaily smokers), 18.4% became daily smokers (nondaily-to-daily smokers), and 11.9% quit smoking (nondaily-to-former smokers) after 12 months. The nondaily-to-daily vs. stable nondaily smoking transition was less likely among those who were aged 65+ (p=0.018), male (pnon-Hispanic Asian (p=0.032), without a college degree, widowed/divorced/separated (p=0.013) or never married (p=0.011), and current users of cigars (p=0.003) compared with the appropriate reference group. Conclusions While over two-thirds of nondaily smokers in the USA remain as such after 12 months, others become daily smokers or quit. The likelihood of remaining stable nondaily smokers and of transition from nondaily-to-daily and nondaily-to-former smokers is associated with socio-demographics factors and current use of cigars and smokeless tobacco.

    The mechanisms of cellular damage that lactic acid bacteria incur during freeze-thaw processes have not been elucidated to date. Fourier transform infrared spectroscopy was used to investigate in situ the lipid phase transition behavior of the membrane of Lactobacillus delbrueckii ssp. bulgaricus CFL1 cells during the freeze-thaw process. Our objective was to relate the lipid membrane behavior to membrane integrity losses during freezing and to cell-freezing resistance. Cells were produced by using 2 different culture media: de Man, Rogosa, and Sharpe (MRS) broth (complex medium) or mild whey-based medium (minimal medium commonly used in the dairy industry), to obtain different membrane lipid compositions corresponding to different recovery rates of cell viability and functionality after freezing. The lipid membrane behavior studied by Fourier transform infrared spectroscopy was found to be different according to the cell lipid composition and cryotolerance. Freeze-resistant cells, exhibiting a higher content of unsaturated and cyclic fatty acids, presented a lower lipid phase transition temperature (Ts) during freezing (Ts=-8°C), occurring within the same temperature range as the ice nucleation, than freeze-sensitive cells (Ts=+22°C). A subzero value of lipid phase transition allowed the maintenance of the cell membrane in a relatively fluid state during freezing, thus facilitating water flux from the cell and the concomitant volume reduction following ice formation in the extracellular medium. In addition, the lipid phase transition of freeze-resistant cells occurred within a short temperature range, which could be ascribed to a reduced number of fatty acids, representing more than 80% of the total. This short lipid phase transition could be associated with a limited phenomenon of lateral phase separation and membrane permeabilization. This work highlights that membrane phase transitions occurring during freeze-thawing play a fundamental role in the

    Full Text Available Abstract Background It is important to determine whether unhealthy behaviours might influence transitions out of employment from midlife to old age, given the anticipated need for adults to work for longer. Our aim was to determine the association between repeated assessments of cigarette smoking, heavy/problem alcohol drinking, low physical activity and poor diet at midlife, in relation to work exit from midlife to old age. Methods Data from 7704 participants (5392 men from the Whitehall II cohort study in employment at midlife were used to evaluate the association between unhealthy behaviours and a subsequent transition out of work during 22 years follow-up, using logistic regression models. Results Men who smoked cigarettes, consistently drank alcohol heavily, or reported problem drinking, were more likely to leave employment over follow-up. Women with a consistently poor diet were more likely to leave employment. Associations were stronger when the reason for leaving was health grounds, and stronger among those with persistently unhealthy behaviours over follow-up. The size of the effects were broadly equivalent to one advancing year of age on employment. Physical health functioning over follow-up only partly accounted for the associations with work exit, whereas physical and mental functioning accounted for most of the associations with work exit on health grounds. Conclusions Unhealthy behaviours in midlife are associated with transitions out of employment into old age. Promoting healthy behaviours at midlife might support current policy initiatives aimed at extending working life. Future research should consider possible mechanisms that link behaviours to transitions out of employment, and consider sex differences in larger cohorts.

    The glycosylphosphatidylinositol (GPI)-anchored epithelial extracellular membrane serine protease prostasin (PRSS8) is expressed abundantly in normal epithelia and essential for terminal epithelial differentiation, but down-regulated in human prostate, breast, and gastric cancers and invasive cancer cell lines. Prostasin is involved in the extracellular proteolytic modulation of the epidermal growth factor receptor (EGFR) and is an invasion suppressor. The aim of this study was to evaluate prostasin expression states in the transitional cell carcinomas (TCC) of the human bladder and in human TCC cell lines. Normal human bladder tissues and TCC on a bladder cancer tissue microarray (TMA) were evaluated for prostasin expression by means of immunohistochemistry. A panel of 16 urothelial and TCC cell lines were evaluated for prostasin and E-cadherin expression by western blot and quantitative PCR, and for prostasin gene promoter region CpG methylation by methylation-specific PCR (MSP). Prostasin is expressed in the normal human urothelium and in a normal human urothelial cell line, but is significantly down-regulated in high-grade TCC and lost in 9 (of 15) TCC cell lines. Loss of prostasin expression in the TCC cell lines correlated with loss of or reduced E-cadherin expression, loss of epithelial morphology, and promoter DNA hypermethylation. Prostasin expression could be reactivated by demethylation or inhibition of histone deacetylase. Re-expression of prostasin or a serine protease-inactive variant resulted in transcriptional up-regulation of E-cadherin. Loss of prostasin expression in bladder transitional cell carcinomas is associated with epithelial-mesenchymal transition (EMT), and may have functional implications in tumor invasion and resistance to chemotherapy

    2016-01-01

    The purpose of this article is to publicize an important new Web-based educational program. Recognizing the growing gap in psychiatric-mental health knowledge and the need to better prepare new graduates and nurses transitioning from other service lines into psychiatric inpatient nursing settings, the American Psychiatric Nurses Association developed a 15-hour, modularized curriculum to provide foundational psychiatric-mental health knowledge. This modularized curriculum, called American Psychiatric Nurses Association Transitions in Practice (ATP) focuses on the knowledge and skills to insure the success of nurses new to psychiatric-mental health nursing settings and to improve the overall care for persons with mental health and substance use disorders. The ATP program is also proving to be useful content for nurses in emergency departments, hospitals, and other health settings to improve their care of patients with psychiatric and mental health needs. A summary of the program modules and a toolkit with suggested measures for nurses, patients, and agency outcomes is described. Feedback from participants completing the ATP program within the first 6 months is overwhelmingly positive and holds promise for widespread application across a variety of health care settings.

    To determine whether reproductive hormones are related to sexual function during the menopausal transition. The Study of Women's Health Across the Nation (SWAN) is a multiethnic cohort study of the menopausal transition located at seven US sites. At baseline, the 3302 community-based participants, aged 42-52, had an intact uterus and at least one ovary and were not using exogenous hormones. Participants self-identified as White, Black, Hispanic, Chinese, or Japanese. At baseline and at each of the 10 follow-up visits, sexual function was assessed by self-administered questionnaires, and blood was drawn to assay serum levels of T, estradiol, FSH, SHBG, and dehydroepiandrosterone sulfate. Self-reported frequency of masturbation, sexual desire, sexual arousal, orgasm, and pain during intercourse. Masturbation, sexual desire, and arousal were positively associated with T. Masturbation, arousal, and orgasm were negatively associated with FSH. Associations were modest. Estradiol was not related to any measured sexual function domain. Pain with intercourse was not associated with any hormone. Reproductive hormones were associated with sexual function in midlife women. T was positively associated, supporting the role of androgens in female sexual function. FSH was negatively associated, supporting the role of menopausal status in female sexual function. The modest associations in this large study suggest that the relationships are subtle and may be of limited clinical significance.

    To develop a method for investigating co-authorship patterns and author team characteristics associated with the publications in high-impact journals through the integration of public MEDLINE data and institutional scientific profile data. For all current researchers at Columbia University Medical Center, we extracted their publications from MEDLINE authored between years 2007 and 2011 and associated journal impact factors, along with author academic ranks and departmental affiliations obtained from Columbia University Scientific Profiles (CUSP). Chi-square tests were performed on co-authorship patterns, with Bonferroni correction for multiple comparisons, to identify team composition characteristics associated with publication impact factors. We also developed co-authorship networks for the 25 most prolific departments between years 2002 and 2011 and counted the internal and external authors, inter-connectivity, and centrality of each department. Papers with at least one author from a basic science department are significantly more likely to appear in high-impact journals than papers authored by those from clinical departments alone. Inclusion of at least one professor on the author list is strongly associated with publication in high-impact journals, as is inclusion of at least one research scientist. Departmental and disciplinary differences in the ratios of within- to outside-department collaboration and overall network cohesion are also observed. Enrichment of co-authorship patterns with author scientific profiles helps uncover associations between author team characteristics and appearance in high-impact journals. These results may offer implications for mentoring junior biomedical researchers to publish on high-impact journals, as well as for evaluating academic progress across disciplines in modern academic medical centers.

    Academic stress is defined as a physiological, emotional, cognitive, and behavioral activation reaction to stimuli. This stress can impact students' ability to cope with the school environment. To identify the psychophysiological manifestations associated with high-level academic stress in public university students in Mexico. A representative random sampling of 527 students was evaluated during 2012. The Academic Stress Symptom Inventory and the Rossi classification were used; data were analyzed with a binary logistic regression analysis to estimate association between psychophysiological manifestations and the high level of academic stress in public university students. Results indicated a meaningful association between high levels of academic stress situations and psychophysiological manifestations such as concentration and memory problems, mental blocks and chronic fatigue, drowsiness, and despair. Identifying academic stress situations and students' maladaptive responses may help promote timely attention to psychophysiological manifestations before they exacerbate and become harmful to college students' health. © 2016 Wiley Periodicals, Inc.

    Opinions about public lands and the actions of private non-industrial forest owners in the western United States play important roles in forested landscape management as both public and private forests face increasing risks from large wildfires, pests and disease. This work presents the responses from two surveys, a random-sample telephone survey of more than 1500 residents and a mail survey targeting owners of parcels with 10 or more acres of forest. These surveys were conducted in three counties (Wallowa, Union, and Baker) in northeast Oregon, USA. We analyze these survey data using structural equation models in order to assess how individual characteristics and understanding of forest management issues affect perceptions about forest conditions and risks associated with declining forest health on public lands. We test whether forest understanding is informed by background, beliefs, and experiences, and whether as an intervening variable it is associated with views about forest conditions on publicly managed forests. Individual background characteristics such as age, gender and county of residence have significant direct or indirect effects on our measurement of understanding. Controlling for background factors, we found that forest owners with higher self-assessed understanding, and more education about forest management, tend to hold more pessimistic views about forest conditions. Based on our results we argue that self-assessed understanding, interest in learning, and willingness to engage in extension activities together have leverage to affect perceptions about the risks posed by declining forest conditions on public lands, influence land owner actions, and affect support for public policies. These results also have broader implications for management of forested landscapes on public and private lands amidst changing demographics in rural communities across the Inland Northwest where migration may significantly alter the composition of forest owner goals

    Full Text Available Background: This study examined the sociodemographic and perceived environmental factors associated with public bicycle use among Taiwanese urban adults. Methods: A random-digit-dialing telephone-based cross-sectional survey was administered to Taiwanese urban adults aged 20–64 years in 2015. Data on sociodemographic variables, perceived environmental factors (for attributes identified in the International Physical Activity Questionnaire-Environmental Module, and public bicycle use were obtained from 1002 adults in three cities. Adjusted logistic regression was used. Results: After adjustment for potential confounders, the results showed that adults aged 20–29 years (odds ratio (OR = 4.42 with a university degree or higher (OR = 2.03 were more likely to use public bicycles. In addition, adults living in Kaohsiung City were less likely to use public bicycles (OR = 0.24. Adults who saw people being active (OR = 1.76; 95% CI: 1.05–2.86 and had positive aesthetic experiences of their environment (OR = 1.69 were more likely to use public bicycles. Conclusions: Our findings suggest that seeing physically active people and positive aesthetic perceptions of the environment are key factors for developing transportation policies and intervention strategies for promoting public bicycle use among Taiwanese urban adults.

    Several options are advocated by policy experts to mitigate alcohol-related harms, although the most effective strategies often have the least public support. While knowledge of tobacco-related health risks predicts support for relevant public health measures, it is not known whether knowledge of alcohol health risks is similarly associated with the acceptability of policies intended to reduce alcohol consumption and related harms. This study aims to gauge public support for a range of alcohol policies and to determine whether or not support is associated with knowledge of a long-term health risk of alcohol consumption, specifically cancer. 2482 adults in New South Wales (NSW), Australia, participated in an online survey. Logistic regression analysis was used to examine the association between demographic data, alcohol consumption, smoking status, knowledge of alcohol as a risk factor for cancer and support for alcohol-related policies. Most participants were supportive of health warnings, restricting access to internet alcohol advertising to young people, and requiring information on national drinking guidelines on alcohol containers. Almost half of participants supported a ban on sport sponsorship, while less than 41% supported price increases, volumetric taxation, or reducing the number of retail outlets. Only 47% of participants identified drinking too much alcohol as a risk factor for cancer. Knowledge of alcohol as a risk factor for cancer was a significant predictor of support for all policies, while level of alcohol consumption had a significant inverse relationship with policy support. The finding that support for alcohol management policies is associated with awareness that drinking too much alcohol may contribute to cancer could assist in the planning of future public health interventions. Improving awareness of the long term health risks of alcohol consumption may be one avenue to increasing public support for effective alcohol harm-reduction policies

  2. Radiation exposures of workers and the public associated with the transport of radioactive material in Germany

    Most radioactive material packages transported emit penetrating ionising radiation and radiation exposures of transport workers and the public may occur during their transport. The radiation exposures incurred by transport workers and members of the public can vary significantly depending on a number of factors: most important is the type of radiation emitted (primarily gamma and neutron radiation), the radiation field intensity in the surrounding of a package and conveyance and the duration of exposure to ionising radiation. The information and guidance material on occupational exposures has primarily been derived from a survey and analysis of personal monitoring data provided by a number of commercial transport operators in Germany known as major carrier and handler organisations of fuel cycle and non-fuel cycle material (in terms of the number of pack-ages and the activity carriaged). To some extent advantage was taken of compilations of statistical transport and exposure data collated within other transport safety analysis studies including research projects funded by the European Commission. The exposure data collected cover the time period of the last 4 - 8 years and are most representative for routine transport operations closely related to the movement phase of packaged radioactive material, i.e. receipt, vehicle loading, carriage, in-transit storage, intra-/intermodal transfer, vehicle unloading and delivery at the final destination of loads of radioactive material and packages and the related supervisory and health physics functions. Radiation dose monitoring of members of the public, however, is generally impracticable and, consequently, the information available relies on employing dose assessment models and reflects radiation exposures incurred by hypothetical or critical group individuals of members of the public under normal conditions of transport

    The prevalence of Alzheimer's disease is rising. The large number of new cases identified each year means that many new families will set upon a long trajectory of caring for a relative with dementia. Diagnostic disclosure of Alzheimer's disease marks the official transition to the caregiver role, yet this early period of the caregiver career have rarely been studied. Based on Meleis's theoretical framework for role transition, the objectives of this study were to document the characteristics of the caregiving context during the transition to the caregiver role following diagnostic disclosure of Alzheimer's disease and to compare these characteristics by caregiver gender and kinship tie to the relative. A descriptive design was used. Data were collected using standardized measures selected in accordance with the role transition theoretical framework. The sample recruited in Quebec (Canada) cognition clinics comprised 122 caregivers of an elderly relative diagnosed with Alzheimer's disease in the past nine months. Findings reveal the context of care to be marked by several challenges for caregivers. The majority of caregivers receives little informal support, has poor knowledge of available formal services, and has difficulty planning ahead for the relative's future care needs. Caregivers themselves report a lack of preparedness to provide care. Compared with men caregivers, women seem to have more problems controlling disturbing thoughts about their new caregiver role and to experience more family conflicts and psychological distress. Compared with offspring caregivers, spouse caregivers are less able to respond to the relative's disruptive behaviors, make less use of problem-solving strategies, and report fewer family conflicts. The challenges faced by caregivers during the transition to the caregiver role are sensitive to nursing interventions. Pro-active interventions from the outset of the caregiving career, such as early assessment of caregiver needs for

Participants completing random-digit dialed telephone survey (n = 906). Survey measures assessed stated support for 5 policies to promote physically active transportation, access to active transportation facilities, and time spent in a car. County-level estimates included household car dependence and funding for bicycle-pedestrian projects. Multivariable generalized linear mixed models using binary distribution and logit link, accounting for clustering within county. Respondents supported policies for accommodating bicyclists and pedestrians through street improvements (89%), school active transportation programs (75%), employer-funded active commuting incentives (67%), and allocation of public funding (68%) and tax support (56%) for building and maintaining public transit. Residents spending >2 h/d (vs public transit (OR: 1.85; CI: 1.24-2.77) improvements. Residents in counties investing >$1.6 million in bicycle and pedestrian improvements expressed greater support for funding (OR: 1.71; CI: 1.04-2.83) and tax increases (OR: 1.73; CI: 1.08-2.75) for transit improvements compared to those with lower prior investments (transportation is higher where relevant investments in active transportation infrastructure are large (>$1.6 M), public transit is nearby, and respondents drive >2 h/d.

    In order to support plans and actions that combat the local increasing overweight and obesity prevalence in adolescents, the factors associated to weight excess in public school students from Montes Claros, MG, Southeast Brazil, were studied. Cross-sectional study with a sample of adolescents from the public schools of the city. The nutritional status was evaluated and an inquiry was carried out in the schools to determine food consumption and practice of physical activities. Factors associated to weight excess were assessed by bivariate analysis followed by logistic regression. Weight excess prevalence was detected in 18.5% of the 535 adolescents evaluated. The factors associated to weight excess were: per capita income above half minimum wage (OR 1.99; 95%CI 1.01-3.93), candy consumption above two daily portions (OR 1.94; 95%CI 1.13-3.32) and absence of sport activity during leisure time (OR 2.54; 95%CI 1.15-5.59). The proportion of weight excess in adolescents from public schools is relevant and associated with socioeconomic condition of the family, bad eating habits and sedentary life.

    Full Text Available Existing evidence on the association between built environment and cardiovascular disease (CVD risk factors focused on the general population, which may not generalize to higher risk subgroups such as those with lower socio-economic status (SES. We examined the associations between distance to 5 public amenities from residential housing (public polyclinic, subsidized private clinic, healthier eatery, public park and train station and 12 CVD risk factors (physical inactivity, medical histories and unhealthy dietary habits among a study sample of low income Singaporeans aged ≥40years (N=1972. Using data from the Singapore Heart Foundation Health Mapping Exercise 2013–2015, we performed a series of logistic mixed effect regressions, accounting for clustering of respondents in residential blocks and multiple comparisons. Each regression analysis used the minimum distance (in km between residential housing and each public amenity as an independent continuous variable and a single risk factor as the dependent variable, controlling for demographic characteristics. Increased distance (geographical inaccessibility to a train station was significantly associated with lower odds of participation in sports whereas greater distance to a subsidized private clinic was associated with lower odds of having high cholesterol diagnosed. Increasing distance to park was positively associated with higher odds of less vegetable and fruits consumption, deep fried food and fast food consumption in the preceding week/month, high BMI at screening and history of diabetes, albeit not achieving statistical significance. Our findings highlighted potential effects of health-promoting amenities on CVD risk factors in urban low-income setting, suggesting gaps for further investigations.

    Kiefer, Richard C.; Freimuth, Robert R.; Chute, Christopher G; Pathak, Jyotishman

    Gene Wiki Plus (GeneWiki+) and the Online Mendelian Inheritance in Man (OMIM) are publicly available resources for sharing information about disease-gene and gene-SNP associations in humans. While immensely useful to the scientific community, both resources are manually curated, thereby making the data entry and publication process time-consuming, and to some degree, error-prone. To this end, this study investigates Semantic Web technologies to validate existing and potentially discover new genotype-phenotype associations in GWP and OMIM. In particular, we demonstrate the applicability of SPARQL queries for identifying associations not explicitly stated for commonly occurring chronic diseases in GWP and OMIM, and report our preliminary findings for coverage, completeness, and validity of the associations. Our results highlight the benefits of Semantic Web querying technology to validate existing disease-gene associations as well as identify novel associations although further evaluation and analysis is required before such information can be applied and used effectively.

    Military recruiting is thoroughly integrated in American public schools. Federal legislation mandates that every public school receiving federal funding open its doors to military recruiters in the same capacity as any postsecondary university or job organization, lest that school risk losing all federal funds.

    During July 2016-January 2017, two unrelated measles cases were identified in the Denver, Colorado area after patients traveled to countries with endemic measles transmission. Each case resulted in multiple exposures at health care facilities and public venues, and activated an immediate and complex response by local and state public health agencies, with activities led by the Tri-County Health Department (TCHD), which serves Adams, Arapahoe, and Douglas counties. To track the economic burden associated with investigating and responding to single measles cases, personnel hours and supply costs incurred during each investigation were tracked prospectively. No secondary cases of measles were identified in either investigation. Postexposure prophylaxis (PEP) was administered to 31 contacts involving the first case; no contacts of the second case were eligible for PEP because of a delay in diagnosing measles disease. Public health costs of disease investigation in the first and second case were estimated at $49,769 and $18,423, respectively. Single measles cases prompted coordinated public health action and were costly and resource-intensive for local public health agencies.

    The glass transition temperature Tg of biopreservative formulations is important for predicting the long-term storage of biological specimens. As a complementary tool to thermal analysis techniques, which are the mainstay for determining Tg, molecular dynamics simulations have been successfully applied to predict the Tg of several protectants and their mixtures with water. These molecular analyses, however, rarely focused on the glass transition behavior of aqueous trehalose solutions, a subject that has attracted wide scientific attention via experimental approaches. Important behavior, such as hydrogen-bonding dynamics and self-aggregation has yet to be explored in detail, particularly below, or in the vicinity of, Tg. Using molecular dynamics simulations of several dynamic and thermodynamic properties, this study reproduced the supplemented phase diagram of trehalose-water mixtures (i.e., Tg as a function of the solution composition) based on experimental data. The structure and dynamics of the hydrogen-bonding network in the trehalose-water systems were also analyzed. The hydrogen-bonding lifetime was determined to be an order of magnitude higher in the glassy state than in the liquid state, while the constitution of the hydrogen-bonding network exhibited no noticeable change through the glass transition. It was also found that trehalose molecules preferred to form small, scattered clusters above Tg, but self-aggregation was substantially increased below Tg. The average cluster size in the glassy state was observed to be dependent on the trehalose concentration. Our findings provided insights into the glass transition characteristics of aqueous trehalose solutions as they relate to biopreservation.

    Problem statement: The Association of Southeast Asian Nations (ASEAN) envisioned an integrated regional community by the year 2015, following the European Union model. However, unlike the European Community which was formed after years of discussion at different levels of society, institutions and government, ASEAN was rather quick to conceptualize this initiative, without seeking the feedbacks for the public. Consequently, ASEAN Community initiative has been criticized for being elitist in i...

    National public health associations (PHAs) are key partners with governments and communities to improve, protect and promote the public's health. Governance and organizational capacity are among the key determinants of a PHA's effectiveness as an advocate for appropriate public health policies and practice. During 2014, the World Federation of Public Health Associations (WFPHA) conducted an on-line survey of its 82 PHA members, to identify the state of organizational governance of national public health associations, as well as the factors that influence optimal organizational governance. The survey consisted of 13 questions and focused on the main elements of organizational governance: cultivating accountability; engaging stakeholders; setting shared direction; stewarding resources; and, continuous governance enhancement. Four questions included a qualitative open-ended response for additional comments. The survey data were analyzed using Microsoft Excel. The qualitative data was analyzed using thematic content analysis Responses were received from 62 PHAs, constituting a 75.6 % response rate. The two most important factors that support governance effectiveness were a high degree of integrity and ethical behavior of the PHA's leaders (77 %) and the competence of people serving on the PHA's governing body (76 %). The lack of financial resources was considered as the most important factor that negatively affected organizational governance effectiveness (73 %). The lack of mentoring for future PHA leaders; ineffective or incompetent leadership; lack of understanding about good governance practices; and lack of accurate information for strategic planning were identified as factors influencing PHA governance effectiveness. Critical elements for PHA sustainability included diversity, gender-responsiveness and inclusive governance practices, and strategies to build the future generation of public health leaders. National PHA have a responsibility to put into place

    This study examines sociodemographic characteristics and social-environmental factors associated with bullying during the elementary to middle school transition from a sample of 5th-grade students (n = 300) in 3 elementary schools at Time 1. Of these, 237 participated at Time 2 as 6th-grade students. Using cluster analyses, we found groups of students who reported no increase in bullying, some decrease in bullying, and some increase in bullying. Students who reported increases in bullying also reported decreases in school belongingness and teacher affiliation and increases in teacher dissatisfaction. Students who reported decreases in bullying also reported decreases in victimization. These findings suggest that changes across the transition in students' relations to school and their teachers are predictive of changes in bullying.

    Social capital is a critical resource for physical and mental health among older adults, but few studies have investigated this relationship in Chinese populations, and specifically among those with low socioeconomic status. This study examined the association between depression and cognitive social capital (reciprocity and trust) and structural social capital (social participation) in a community sample of older adults living in public housing in Macau (SAR), China (N = 366). Multivariable linear regressions estimated the associations between dimensions of social capital and depression, while adjusting for potential confounders. Significant inverse associations were found between reciprocity and trust and depression. No association was found between social participation and depression. Poor self-reported health was a robust correlate of depression in all models tested. Future studies are needed to evaluate whether enhancing social capital may reduce depression among Chinese older adults living in poverty.

    Chile is a post-transitional country evolving towards a stationary population pyramid, which may be associated with increasing preterm birth (PTB) rates. This study aimed to compare maternal sociodemographic characteristics between the start of the post-transition phase (1994) and an established stage (2013) and to evaluate associations between these characteristics and PTB. An observational analytic design was conducted using national birth records (n = 4,956,311). Variables analysed in the 20 birth cohorts from 1994 to 2013 were: length of gestation (preterm 35 years); education level (12 years of education); employment; marital status; area of residence; and type of birth (singleton, twins, and triplets or higher order). The prevalence of PTB was expressed as a percentage, and associations between PTB and predictor variables were analysed using logistic regression models. Education level, age >35 years, maternal employment, unmarried status, twin delivery and urban residency rates increased between 1994 and 2013. According to the adjusted models, age >35 years and delivery of more than two foetuses were risk factors for all PTB subtypes. Maternal employment was a risk factor for moderate/severe, late and total PTB, and a low level of education was a risk factor for late and total PTB. On the other hand, age ≤19 years was protective against all PTB subtypes. All maternal characteristics changed between 1994 and 2013. Furthermore, the prevalence of PTB increased for all predictor variables studied over this period. Copyright © 2017 The Royal Society for Public Health. Published by Elsevier Ltd.

    The purpose of this study was twofold: (1) To investigate the individual- and system-level characteristics associated with high utilization of acute mental health services according to a widely-used theory of service use-Andersen's Behavioral Model of Health Service Use -in individuals enrolled in a large, public-funded mental health system; and (2) To document service utilization by high use consumers prior to a transformation of the service delivery system. We analyzed data from 10,128 individuals receiving care in a large public mental health system from fiscal years 2000-2004. Subjects with information in the database for the index year (fiscal year 2000-2001) and all of the following 3 years were included in this study. Using logistic regression, we identified predisposing, enabling, and need characteristics associated with being categorized as a single-year high use consumer (HU: >3 acute care episodes in a single year) or multiple-year HU (>3 acute care episodes in more than 1 year). Thirteen percent of the sample met the criteria for being a single-year HU and an additional 8% met the definition for multiple-year HU. Although some predisposing factors were significantly associated with an increased likelihood of being classified as a HU (younger age and female gender) relative to non-HUs, the characteristics with the strongest associations with the HU definition, when controlling for all other factors, were enabling and need factors. Homelessness was associated with 115% increase in the odds of ever being classified as a HU compared to those living independently or with family and others. Having insurance was associated with increased odds of being classified as a HU by about 19% relative to non-HUs. Attending four or more outpatient visits was an enabling factor that decreased the chances of being defined as a HU. Need factors, such as having a diagnosis of schizophrenia, bipolar disorder or other psychotic disorder or having a substance use disorder

    With energy security, economic stabilization, and environmental sustainability being at the forefront of US policy making, the development of biodiesel production and use within the United States has been growing at an astonishing rate. According to the latest DOE energy report, biodiesel production and consumption in the US has decreased since its peak in 2008, but still remains an important factor in the US energy mix. However, despite recent studies showing that B5 has similar performance qualities to that of the currently used ultra-low-sulfur petroleum diesel (ULSD) fleet managers and corporations still remain hesitant regarding a switch to B5. This research examined the major areas of concern that arise with transitioning fleets from ULSD to B5 with the goal of alleviating those concerns with quantitative results from an actual fleet implementation and transition. In conjunction with the Pennsylvania Department of Transportation (PennDOT) a comparison of cost, cold weather fuel properties, engine performance, fuel economy, and maintenance and repairs was conducted using data obtained over 3 years from a pilot study. The results found that B5 performed as well or better than ULSD in all performance metrics. - Research Highlights: →Conducted multi-year study of a DOT fleet transition from ULSD to biodiesel (B5)→No significant difference in cold weather performance, engine power output, or torque→No significant difference in fuel economy→No resulting increase in maintenance and repair costs or frequency→Life-cycle costing revealed no hidden costs as a result of B5 implementation

    Full Text Available Objectives:Information technologies have been developing very rapidly, also in the case of occupational activities. Epidemiological studies have shown that employees, who work with computers, are more likely to complain of musculoskeletal disorders (MSD. The aim of this study was to evaluate associations between neck MSD and individual and work related factors. Materials and Methods: The investigation which consisted of two parts - a questionnaire study (using Nordic Musculoskeletal questionnaire and Copenhagen Psychosocial Questionnaire and a direct observation (to evaluate ergonomic work environment using RULA method was carried out in three randomly selected public sector companies of Kaunas. The study population consisted of 513 public service office workers. Results: The survey showed that neck MSDs were very common in the investigated population. The prevalence rate amounted to 65.7%. According to our survey neck MSDs were significantly associated with older age, bigger work experience, high quantitative and cognitive job demands, working for longer than 2 h without taking a break as well as with higher ergonomic risk score. The fully adjusted model working for longer than 2 h without taking a break had the strongest associations with neck complaints. Conclusion: It was confirmed, that neck MSDs were significantly associated with individual factors as well as conditions of work, therefore, preventive acions against neck complaints should be oriented at psychosocial and ergonomic work environment as well as at individual factors.

    Professional development of public health leaders requires a form of instruction which is competency-based to help them develop the abilities to address complex and evolving demands of health care systems. Concurrently, emotional intelligence (EI) is a key to organisational success. Our aim was twofold: i) to assess the relationship between the level of self-assessed public health and EI competencies among Master of European Public Health (MEPH) students and graduates at Maastricht University, and; ii) to determine the relationship between different groups of public health competencies and specific EI skills. A cross-sectional study was conducted including all recent MEPH graduates and students from 2009-2012, out of 67 eligible candidates N = 51 were contacted and N = 33 responded (11 males and 22 females; overall response: 64.7%).Two validated tools were employed: i) public health competencies self-assessment questionnaire, and; ii) Assessing Emotions Scale. Females scored higher than males in all seven domains of the self-assessed key public health competencies (NS) and emotional intelligence competences (P = 0.022). Overall, the mean value of public health competencies was the lowest in students with "staff" preferences and the highest among students with mixed job preferences (P leadership.

    To describe the epidemiology and rates of all health care-associated bloodstream infections (HA-BSIs) and of specific HA-BSI subsets in public hospitals in Queensland. Standardised HA-BSI surveillance data were collected in 23 Queensland public hospitals, 2008-2012. HA-BSIs were prospectively classified in terms of place of acquisition (inpatient, non-inpatient); focus of infection (intravascular catheter-associated, organ site focus, neutropenic sepsis, or unknown focus); and causative organisms. Inpatient HA-BSI rates (per 10,000 patient-days) were calculated. There were 8092 HA-BSIs and 9418 causative organisms reported. Inpatient HA-BSIs accounted for 79% of all cases. The focus of infection in 2792 cases (35%) was an organ site, intravascular catheters in 2755 (34%; including 2240 central line catheters), neutropenic sepsis in 1063 (13%), and unknown in 1482 (18%). Five per cent (117 of 2240) of central line-associated BSIs (CLABSIs) were attributable to intensive care units (ICUs). Eight groups of organisms provided 79% of causative agents: coagulase-negative staphylococci (18%), Staphylococcus aureus (15%), Escherichia coli (11%), Pseudomonas species (9%), Klebsiella pneumoniae/oxytoca (8%), Enterococcus species (7%), Enterobacter species (6%), and Candida species (5%). The overall inpatient HA-BSI rate was 6.0 per 10,000 patient-days. The rates for important BSI subsets included: intravascular catheter-associated BSIs, 1.9 per 10,000 patient-days; S. aureus BSIs, 1.0 per 10,000 patient-days; and methicillin-resistant S. aureus BSIs, 0.3 per 10,000 patient-days. The rate of HA-BSIs in Queensland public hospitals is lower than reported by similar studies elsewhere. About one-third of HA-BSIs are attributable to intravascular catheters, predominantly central venous lines, but the vast majority of CLABSIs are contracted outside ICUs. Different sources of HA-BSIs require different prevention strategies.

  3. 'Intimate mothering publics': comparing face-to-face support groups and Internet use for women seeking information and advice in the transition to first-time motherhood.

    2015-01-01

    This paper seeks to contribute to an understanding of the changing nature of support and information-seeking practices for women in the transition to first-time motherhood. In the context of increasing digitalisation, the significance of new virtual spaces for parenting is discussed. The paper demonstrates how women seek out alternative forms of expertise (specifically, non-medical expertise) and social support. The author argues for the importance of 'intimate mothering publics' through which women gather experiential information and practical support. These publics can act as a space for women to 'test' or legitimise their new identity as a mother. Intimate mothering publics are particularly useful for thinking about the meaning-making practices and learning experiences that occur during intimate online and face-to-face interactions. A variety of types of online support may be used during pregnancy. Surreptitious support in particular involves users invisibly receiving advice, information and reassurance that might otherwise be lacking. Access to intimate mothering publics is motivated by a number of factors, including feelings of community or acceptance, the desire to be a good mother or parent, emotional support and the need for practical and experiential advice.

    We examined the impact of work presented in the plenary sessions at the meeting of The American Association for Thoracic Surgery (AATS), by determining how frequently the published papers corresponding to the session presentations during the past 20 years, were cited; those that were most cited were identified. We reviewed the AATS meeting programs from the 20-year period from 1994 to 2014 and identified the corresponding publications in the Journal of Thoracic and Cardiovascular Surgery (JTCVS) from all abstracts presented at the plenary sessions. Papers were categorized as cardiac, thoracic, or congenital. References were evaluated for subsequent citation in the Web of Science (WoS), and Google Scholar (GS). We determined both the median number of citations overall, and per year. For comparison, we evaluated numbers of citations in WoS from current JTCVS papers in issues containing the 3 most-cited plenary session papers. Among 195 published plenary papers, the median number of citations in WoS and GS was 49 and 76, respectively. The median total number of citations in WoS was as follows: 51 for cardiac-category papers (n = 105); 61 for thoracic (n = 55), and 41 for congenital (n = 35). These values were higher than the median total number of citations for contemporary nonplenary JTCVS papers: cardiac (22, n = 55; P papers published in JTCVS. The median number of citations per year since publication for plenary publications was 5.9 (cardiac), 6 (thoracic), and 3.7 (congenital), respectively. Publications corresponding to the plenary sessions of the AATS are highly cited and include some of the seminal studies in our field in the past 20 years.

    To determine the prevalence of glycaemic control and factors associated with poor glycaemic control [glycosylated haemoglobin (HbA1c) ≥6.5%] among patients with type 2 diabetes treated in public health clinics in Johor, Malaysia. Cross-sectional study. A review of all patients aged over 18 years and with a diagnosis of type 2 diabetes for >1 year. The National Diabetic Registry was used as the database for attendees at public health clinics in Johor Bahru between January and December 2013. A required sample of 660 was calculated, and a random sampling method was applied to acquire patient information across the 13 public health clinics in Johor Bahru. All relevant information (e.g. HbA1c, type of treatment and other parameters for glycaemic control) were abstracted from the registry. Sixty-eight percent of 706 patients had HbA1c >6.5%, and mean HbA1c was 7.8%. Younger patients (72.3%) had poorer glycaemic control than older patients (63.0%), and most patients with poor glycaemic control were obese (79.2%). Approximately 31.7% of patients did not achieve the target blood pressure 5 years), body mass index (obese), type of treatment (diet therapy vs combination therapy) and abnormal lipid profile were significantly associated with increased odds of HbA1C >6.5%. More than half (68%) of the patients with diabetes had HbA1c >6.5%. This highlights the importance of providing organized care to manage patients with diabetes in the primary care setting, such as weight reduction programmes, proper prescribing treatment, and age- and gender-specific groups to ensure good glycaemic control.

    2016-03-06

    By the end of fiscal year 2025, the U.S. Department of Energy (DOE) Office of Legacy Management (LM) is anticipating adding 17 sites remediated under Title II of the Uranium Mill Tailings Radiation Control Act (UMTRCA) to the current inventory of 90 sites that it manages. Among the new sites are ones where federal public lands occur within the proposed long-term care boundary, the boundary determined by the Nuclear Regulatory Commission and LM as necessary to maintain site protectiveness for the entombed uranium mill tailings and residual groundwater contamination. For these sites, public land withdrawals for land and minerals will need to be established. LM’s primary mission at UMTRCA sites is to protect the public and the environment from exposure to contamination at the sites. For the sites with public lands or federally controlled minerals that will be transferring to LM, the Office will apply to the Department of the Interior (DOI) Bureau of Land Management (BLM) for new, public land and mineral withdrawals. At most current LM UMTRCA sites that involved public lands and minerals, DOI granted DOE “full administrative jurisdiction” and permanent withdrawals. Hence, these withdrawals are, permanently, no longer subject to public land, mining, and mineral-leasing laws and regulations. LM is coordinating with DOI/BLM in Wyoming to permanently withdraw full and partial jurisdiction at future UMTRCA Title II sites in that state. This approach would allow LM to fully administer surface lands and minerals, where necessary, and DOI and LM to administer surface lands and leasable minerals where it would not jeopardize sites’ radiological safety and long-term public and environmental protection. This “shared-jurisdiction approach” will meet LM’s strategic goal of protecting human health and the environment but also allow BLM to fulfill their mission to “manage and conserve the lands under the mandate of multiple-use and sustained yield.” In addition, LM

    This paper discusses the association between the morphology of tree planting in urban riverside brown field and user activities. With the growth of popularity, the revitalisation of urban public space is also promising. This research used drone photography and mapping to systematically surveys sample sites. An original observation study of user activities proceed in four sample public spaces in Sheffield. The study results found there are huge popularity and duration difference of user activities between various tree planting morphologies and typologies. The public space with lawn and rounded by mature trees attracted most users with the most activity types; the neat and silent public space is the favourite choice of lunch and reading, meanwhile it got the longest activity duration; but the space with sparse morphology and small trees are more likely be forgotten and abandoned. This finding offered a great opportunity for urban public space revitalisation in post-industrial cities.

Cross-sectional study of a representative sample of 9 982 students aged between 14 and 19 years. Logistic regression models were used to estimate odds ratio (OR) with 95% confidence interval (CI95%). 27% of students presented DS, with higher proportion among women (34%) than among men (18%). Factors associated with DS were being female (OR=2.25 CI95% 1.86-2.71); low self-esteem (OR=2.77 CI95% 2.41 -3.19); consuming alcohol (OR= 1.72 CI95% 1.46-2.02), consuming tobacco (OR= 1.57 CI95% 1.31-1.88), consuming illegal drugs (OR=1.63 CI95% 1.29-2.05), domestic violence (OR=2.05 CI95% 1.77-2.39), and low communication between parents and their children (OR=1.78 CI95% 1.59-2.00). Depressive symptomatology among high-school students in Mexico is a public health issue.There is a need for intervention programs aimed at tackling the associated risk factors.

  11. Transition of Higher Education Graduates to the Labour Market: Are Employment Procedures More Meritocratic in the Public Sector?

    2011-01-01

    As an employer, the public sector might be expected to be more meritocratic than the private sector, because of its democratic values and more transparent appointments procedures. In this context meritocratic means that the employer only considers characteristics such as degree and grades, relevant for the position in question. The individuals in…

    2016-12-01

    Suicide is a leading cause of death for transition-aged youth (TAY), and yet few studies examine correlates of suicidal ideation specifically in this age demographic (age 18-24 years). The transition to adulthood is a unique context, marked by novel stressors (e.g., joining the workforce) and increased independence, which may influence risk factors for suicidal ideation. This study examined correlates of suicidal ideation in TAY and adults and contrasted profiles across age. We used 4 biannual cycles (2005, 2007, 2009, 2011) of the Canadian Community Health Survey, a population-based cross-sectional survey on health. We used logistic regression to assess the association between suicidal ideation and depression, distress, alcohol use, smoking, exercise, sedentary behaviour, chronic illness, restrictions to daily living, perceived physical and mental health, and perceived social support independently in both TAY ( n = 4427) and adults ( n = 14,452). We subsequently assessed possible interactions with age (18-24 v. 25-44 years) and sex and differences in help-seeking behaviour in a combined model. TAY exhibited higher rates of suicidal ideation than adults did ( P suicidal ideation in TAY. Notably, alcohol abstinence was associated with decreased suicidal ideation in TAY but not for adults. Moreover, when depressed, TAY were significantly less likely to have received professional mental health help than adults (odds ratio = 0.64, 95% CI, 0.43 to 0.94). Suicidal ideation is more prevalent in TAY than adults, and its consequences may be aggravated by poor treatment-seeking behaviour in at-risk (i.e. depressed) individuals. These different risk profiles substantiate the recent shift toward clinical interventions focusing on transition-aged youth, rather than traditional child (18 years) services.

    In the context of the nutrition transition and associated changes in the food retail sector, to examine the socio-economic characteristics and motivations of shoppers using different retail formats (large supermarkets (LSM), medium-sized supermarkets (MSM) or traditional outlets) in Tunisia. Cross-sectional survey (2006). Socio-economic status, type of food retailer and motivations data were collected during house visits. Associations between socio-economic factors and type of retailer were assessed by multinomial regression; correspondence analysis was used to analyse declared motivations. Peri-urban area around Tunis, Tunisia, North Africa. Clustered random sample of 724 households. One-third of the households used LSM, two-thirds used either type of supermarket, but less than 5 % used supermarkets only. Those who shopped for food at supermarkets were of higher socio-economic status; those who used LSM were much wealthier, more often had a steady income or owned a credit card, while MSM users were more urban and had a higher level of education. Most households still frequently used traditional outlets, mostly their neighbourhood grocer. Reasons given for shopping at the different retailers were most markedly leisure for LSM, while for the neighbourhood grocer the reasons were fidelity, proximity and availability of credit (the latter even more for lower-income customers). The results pertain to the transition in food shopping practices in a south Mediterranean country; they should be considered in the context of growing inequalities in health linked to the nutritional transition, as they differentiate use and motivations for the choice of supermarkets v. traditional food retailers according to socio-economic status.

    A few studies have recently reported clockwise and counterclockwise rotations of QRS transition zone as predictors of mortality. However, their prospective correlates and associations with individual cardiovascular disease (CVD) outcomes are yet to be investigated. Among 13 567 ARIC (Atherosclerosis Risk in Communities) study participants aged 45 to 64 years, we studied key correlates of changes in the status of clockwise and counterclockwise rotation over time as well as the association of rotation status with incidence of coronary heart disease (2408 events), heart failure (2196 events), stroke (991 events), composite CVD (4124 events), 898 CVD deaths, and 3469 non-CVD deaths over 23 years of follow-up. At baseline, counterclockwise rotation was most prevalent (52.9%), followed by no (40.5%) and clockwise (6.6%) rotation. Of patients with no rotation, 57.9% experienced counterclockwise or clockwise rotation during follow-up, with diabetes mellitus and black race significantly predicting clockwise and counterclockwise conversion, respectively. Clockwise rotation was significantly associated with higher risk of heart failure (hazard ratio, 1.20; 95% confidence interval [CI], 1.02-1.41) and non-CVD death (hazard ratio, 1.28; 95% CI, 1.12-1.46) after adjusting for potential confounders including other ECG parameters. On the contrary, counterclockwise rotation was significantly related to lower risk of composite CVD (hazard ratio, 0.93; 95% CI, 0.87-0.99]), CVD mortality (hazard ratio, 0.76; 95% CI, 0.65-0.88), and non-CVD deaths (hazard ratio, 0.92; 95% CI, 0.85-0.99 [borderline significance with heart failure]). Counterclockwise rotation, the most prevalent QRS transition zone pattern, demonstrated the lowest risk of CVD and mortality, whereas clockwise rotation was associated with the highest risk of heart failure and non-CVD mortality. These results have implications on how to interpret QRS transition zone rotation when ECG was recorded. © 2017 The Authors

    Full Text Available This study aimed to evaluate the variation associated with repeated measurement of gastrointestinal (GI transit times and the effect of oral ranitidine on GI transit times in healthy dogs using a wireless motility capsule (WMC system. Eight privately owned healthy adult dogs were enrolled, and one developed diarrhea and was removed from the study. For the first 3 repetitions, each dog was fed a standard meal followed by oral administration of a WMC. For the 4th repetition, each dog was given ranitidine hydrochloride (75 mg PO every 12 hours prior to and during assessment of GI transit times. Mean between-subject coefficients of variation for gastric emptying time (GET, small and large bowel transit time (SLBTT, and total transit time (TTT were 26.9%, 32.3%, and 19.6%, respectively. Mean within-subject coefficients of variation for GET, SLBTT, and TTT were 9.3%, 19.6%, and 15.9%, respectively. Median GET, SLBTT, and TTT without ranitidine were 719, 1,636, and 2,735 minutes, respectively. Median GET, SLBTT, and TTT with ranitidine were 757, 1,227, and 2,083 minutes, respectively. No significant differences in GI transit times were found between any of the 4 repetitions. Under these experimental conditions, no significant effects of oral ranitidine on GI transit times were observed.

    Obesity rates in the southern US states are higher than in other states. Historically, large-scale community-based interventions in the United States have not proven successful. With local public health agencies (LPHAs) tasked with prevention, their role in obesity prevention is important, yet little research exists regarding what predicts the participation of LPHAs. Cross-sectional data from the 2008 National Association of City and County Health Officials profile study and two public health conceptual frameworks were used to assess structural and environmental predictors of LPHA participation in obesity prevention. The predictors were compared between southern and nonsouthern states. Univariate and weighted logistic regressions were performed. Analysis revealed that more LPHAs in southern states were engaged in nearly all of the 10 essential public health functions related to obesity prevention compared with nonsouthern states. Presence of community-based organizations and staffing levels were the only significant variables in two of the six logistic regression models. This study provides insights into the success rates of the obesity prevention efforts of LPHAs in southern and nonsouthern states. Future research is needed to understand why and how certain structural elements and any additional factors influence LPHA participation in obesity prevention.

  1. Doing business:an obscure notion of the ethics of public associations in ordinary Chinese

    Along with the notion of being a person(zuo ren 做人), the notion of doing business(zuo shi 做事)in ordinary Chinese is basically an over-all notion of the norms in the practical and associative activities,carrying typically obscure meanings on practice and association affairs in some external world.Ordinary Chinese not only distinguishes these two notions but also defines a dictionary order of them,with the affairs of the internal world prior to those of the external.The fact that the notion of doing business refers to business(shi 事)rather than person(ren 人)makes this order clear at a deeper level.It shows that this notion regards the practical affairs of the external world less important to the person itself than those of the internal.Except for these qualities,the notion of doing business holds some normative meanings,although contains no definite rules.These meanings indirectly relate to the notion of person that people form in their private associations and emerge as some mixture with a tactical attitude out of the need of earning a life.The notion of person gives birth to some obscure requirements,for instance, the requirement of 'doing business in accordance with your conscience' and that of 'doing business seriously'.The core world of family is marginalized in the pubfic transition of associations.There are reasons to anticipate that in this process the notion of doing business will undergo more radical changes than that of being a person.

    To achieve high piezoelectric activity and a wide sintering temperature range, the ceramic system concerning (1 - x)(K(0.48)Na(0.52))(Nb(0.96)Sb(0.04))O(3)-x[Bi(0.5)(Na(0.7)Ag(0.3))(0.5)](0.90) Zn(0.10)ZrO(3) was designed, and the rhombohedral-tetragonal (R-T) phase boundary can drive a high d(33). Phase transition characteristics as well as their effects on the electrical properties were investigated systematically. The R-T coexistence phase boundary (0.04 ≤ x ≤ 0.05) can be driven via modification with BNAZZ, and has been confirmed by XRD and temperature-dependent dielectric constants as well as Raman analysis, and the ceramics possess enhanced piezoelectric properties (d(33) ∼ 425 pC N(-1) and k(p) ∼ 0.43) and a high unipolar strain (∼0.3%). In addition, a wide sintering temperature range of 1050-1080 °C can warrant a large d(33) of 400-430 pC N(-1), which can benefit practical applications. As a result, the addition of BNAZZ is an effective method to improve the electrical properties (piezoelectricity and strain) and sintering behavior of potassium-sodium niobate ceramics.

    It was the purpose of this study to determine the effects of non-esterified fatty acids (NEFA) concentrations at different time periods of the transition period as well as lactation number on metabolism, health, reproduction and milk production in dairy cows. This trial was conducted in a single dairy herd located in Northern Germany. Of the herd, which comprised 330 lactating Holstein cows housed in a free stall barn and fed a total mixed ration (TMR), 83 primiparous and multiparous cows were randomly selected. Animals were checked for body condition score (BCS), locomotion score, calving data, quality of colostrum, reproductive measures, daily rectal temperature of the first 10 days post-partum (p. p.), health data and culling rates up to 200 days in milk (DIM) as well as milk production until 305 DIM. Three different time periods were considered: 3 and 1 week ante partum (a. p.); partus and 1 week p. p.; 3 weeks p. p. Animals with NEFA concentrations ≥ 0.4 mmol/l ante partum had a higher risk of no ovarian activity in week 5 p. p. and of subclinical ketosis post partum than cows with lower NEFA concentrations (p reproduction of dairy cows.

    The prevalence of lumbosacral transitional vertebrae (LTV) was determined by reviewing the pelvic radiographs of 4000 medium- and large-breed dogs of 144 breeds routinely screened for canine hip dysplasia. An LTV was seen in 138 (3.5%) dogs. The prevalence was higher in German Shepherd dogs and Greater Swiss Mountain dogs than in the other breeds, suggesting a genetic predisposition. There was no gender predisposition. The transverse processes of the LTV were divided into three types based on their morphological characteristics: lumbar type or type 1; intermediate type or type 2; and sacral type or type 3. In a symmetric LTV, both transverse processes are of the same type, while in an asymmetric LTV they are not. The frequency of occurrence of symmetric and asymmetric LTV was similar. In symmetric LTV, intermediate-type transverse processes predominated. Most of the asymmetric LTV had an intermediate-type transverse process combined with a lumbar or sacral type, respectively. Highly asymmetric LTV were often angled relative to the adjacent vertebrae. We hypothesize that an LTV is not the result of transformation of a lumbar into a sacral vertebra or vice versa, but rather is an autonomous intermediate type of vertebra. It occurs when the point of contact of the pelvis with the vertebral column is slightly cranial or caudal to its normal position. The resulting formative stimulus on the vertebral ossification centers, sagittally still separated, causes the various morphologies seen in LTV including the asymmetric variations.

    Interface Region Imaging Spectrograph data allow us to study the solar transition region (TR) with an unprecedented spatial resolution of 0.''33. On 2013 August 30, we observed bursts of high Doppler shifts suggesting strong supersonic downflows of up to 200 km s{sup –1} and weaker, slightly slower upflows in the spectral lines Mg II h and k, C II 1336, Si IV 1394 Å, and 1403 Å, that are correlated with brightenings in the slitjaw images (SJIs). The bursty behavior lasts throughout the 2 hr observation, with average burst durations of about 20 s. The locations of these short-lived events appear to be the umbral and penumbral footpoints of EUV loops. Fast apparent downflows are observed along these loops in the SJIs and in the Atmospheric Imaging Assembly, suggesting that the loops are thermally unstable. We interpret the observations as cool material falling from coronal heights, and especially coronal rain produced along the thermally unstable loops, which leads to an increase of intensity at the loop footpoints, probably indicating an increase of density and temperature in the TR. The rain speeds are on the higher end of previously reported speeds for this phenomenon, and possibly higher than the free-fall velocity along the loops. On other observing days, similar bright dots are sometimes aligned into ribbons, resembling small flare ribbons. These observations provide a first insight into small-scale heating events in sunspots in the TR.

    Gaps between evidence-based research and clinical-public health practice have been evident for decades. One of the aims of medical student research is to close this gap. Accordingly, evaluating individual and environmental factors that influence participation of medical students in research are needed to understand and identify potential targets for action. This study aims to identify characteristics of medical student researchers in Colombia and the associated factors with scientific publications. A cross-sectional study of Colombian medical students involved in research using a validated, self-administered, online survey. The survey was distributed through the Colombian Association of Medical Students' Associations (ASCEMCOL). Data sets were analyzed using descriptive and summary statistics. Bivariate analysis and a multiple logistic regression model were conducted to identify predictors of scientific publications. A total of 133 responses were analyzed from students at 12 Colombian cities and 20 higher-education institutions. Although 94% of responders had at least one research proposal, only 57% had completed a project, and 17% had published their findings. Barriers for undertaking research included time restrictions and a lack of mentorship. Motivational factors included opportunity to publish findings and good mentorship. Students planning to do a specialization (OR = 3.25; 95% Confidence interval [CI] = 1.27-8.30), innovators (OR = 3.52; 95%CI = 1.30-9.52) and committed (OR = 3.39; 95%CI = 1.02-11.29), those who had previously published their findings (OR 9.13 IC95% 2.57-32.48), and were further in their medical education (OR 2.26 IC95% 1.01-5.07), were more likely to publish scientific papers. Our findings describe medical students understanding of the process of conducting research in Colombia. Although there appears to be motivation to participate in research, very few students achieve publication. Barriers such as time constraints

    Individuals in need of psychiatric treatment often avoid seeking help because of stigma. This study examined the impact of two stigma dimensions on help-seeking attitudes. Perceived public stigma refers to discrimination and devaluation by others, and anticipated self-stigma refers to internalization of negative stereotypes about people who seek help. Data were from the 2009 Stigma in a Global Context-Belgian Mental Health Study, in which face-to-face interviews were conducted with a representative sample of the general Belgian population. The study reported here included 728 respondents who received a vignette depicting major depression or schizophrenia. Perceived public stigma and anticipated self-stigma were measured with validated instruments. Respondents' attitudes toward help seeking were measured by the importance they assigned to care from formal and informal providers: general practitioners, psychiatrists, psychologists, family members, or friends. Multiple linear regression models were estimated. Respondents with higher levels of anticipated self-stigma attached less importance to care provided by general practitioners or psychiatrists, and those with higher levels of perceived public stigma rated informal help seeking as less important. The gender and the ethnicity of the person and respondents' sociodemographic characteristics had relatively little effect on help-seeking attitudes. Anticipated self-stigma and perceived public stigma appeared to have a differential impact on attitudes toward formal and informal help seeking. Internalization of negative stereotypes was negatively associated with the perceived importance of care from medical providers (general practitioners and psychiatrists). Awareness of stereotypes held by others deterred respondents from acknowledging the importance of informal care.

    Educational technologies such as video cases can improve health professions student learning outcomes, but few studies in dentistry have evaluated video-based technologies. The goal of this study was to compare outcomes associated with video and paper cases used in an introductory public health dentistry course. This was a retrospective cohort study with a historical control group. Based on dual coding theory, the authors tested the hypotheses that dental students who received a video case (n=37) would report better affective, cognitive, and overall learning outcomes than students who received a paper case (n=75). One-way ANOVA was used to test the hypotheses across ten cognitive, two affective, and one general assessment measures (α=0.05). Students in the video group reported a significantly higher overall mean effectiveness score than students in the paper group (4.2 and 3.3, respectively; p<0.001). Video cases were also associated with significantly higher mean scores across the remaining twelve measures and were effective in helping students achieve cognitive (e.g., facilitating good discussions, identifying public health problems, realizing how health disparities might impact their future role as dentists) and affective (e.g., empathizing with vulnerable individuals, appreciating how health disparities impact real people) goals. Compared to paper cases, video cases significantly improved cognitive, affective, and overall learning outcomes for dental students.

    Full Text Available Introduction: Depression is an important global public health problem and one of the most common and serious mental disorders. It initiates with the presentation of symptoms before it progresses to a lifetime disorder. The aim of the study was to determine the prevalence of and factors associated with current depressive symptoms among university staff of a public university in Malaysia. Methodology: A cross-sectional study design was employed using a probability proportionate to size sampling method to select 683 academic and non-academic staff. A structured validated questionnaire was used for data collection. Results: The prevalence of current depressive symptoms was 14.9% (19.0% among males, 12.5% among females. Gender, age, marital status, monthly family income and self-esteem were significantly associated with current depressive symptoms (p<0.05. The logistic regression model showed that male gender (AOR = 2.04; 95%CI 1.29, 3.20 and younger age (AOR = 2.79; 95%CI 1.16, 6.76 were predictors of current depressive symptoms. Conclusion: The prevalence of current depressive symptoms was 14.9% (19.0% among males, 12.5% among females among university staff. A mental health promotion intervention is needed to prevent the threat depression poses on the health of the university staff.

    2010-12-01

    Despite the salience of health disparities in media and policy discourse, little previous research has investigated if imagery associating an illness with a certain racial group influences public perceptions. This study evaluated the influence of the media's presentation of the causes of type 2 diabetes and its implicit racial associations on attitudes toward people with diabetes and preferences toward research spending. Survey participants who viewed an article on genetic causation or social determinants of diabetes were more likely to support increased government spending on research than those viewing an article with no causal language, while participants viewing an article on behavioral choices were more likely to attribute negative stereotypes to people with diabetes. Participants who viewed a photo of a black woman accompanying the article were less likely to endorse negative stereotypes than those viewing a photo of a white woman, but those who viewed a photo of a glucose-testing device expressed the lowest negative stereotypes. The effect of social determinants language was significantly different for blacks and whites, lowering stereotypes only among blacks. Emphasizing the behavioral causes of diabetes, as is common in media coverage, may perpetuate negative stereotypes. While drawing attention to the social determinants that shape these behaviors could mitigate stereotypes, this strategy is unlikely to influence the public uniformly.

    Ponds provide vital ecological services. They are biodiversity hotspots and important breading sites for rare and endangered species, including amphibians and dragonflies. Nevertheless, their number is decreasing due to habitat degradation caused by human activities. The "Ponds with Life" environmental education project was developed to raise public awareness and engagement in the study of ponds by promoting the direct contact between the public and nature, researchers and pedagogical hands-on exploration activities. A pre-post- project survey was set-up to assess the effects of the project on the environmental consciousness, knowledge and attitude changes towards ponds and the associated biodiversity of school students aged 15 to 18. The survey questions were based on Likert scales and their pre-post project comparisons used an innovative multivariate hypothesis testing approach. The results showed that the project improved the students' knowledge and attitudes towards ponds and associated biodiversity, especially the amphibians. Ponds can be found or constructed in urban areas and despite small sized, they proved to be interesting model habitats and living laboratories to foster environmental education, by encompassing a high number of species and a fast ecological succession.

    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.

    The U.S. Department of Homeland Security's Standoff Technology Integration and Demonstration Program is designed to accelerate the development and integration of technologies, concepts of operations, and training to defeat explosives attacks at large public events and mass transit facilities. The program will address threats posed by suicide bombers, vehicle-borne improvised explosive devices, and leave-behind bombs. The program is focused on developing and testing explosives countermeasure architectures using commercial off-the-shelf and near-commercial standoff and remotely operated detection technologies in prototypic operational environments. An important part of the program is the integration of multiple technologies and systems to protect against a wider range of threats, improve countermeasure performance, increase the distance from the venue at which screening is conducted, and reduce staffing requirements. The program will routinely conduct tests in public venues involving successively more advanced technology, higher levels of system integration, and more complex scenarios. This paper describes the initial field test of an integrated countermeasure system that included infrared, millimeter-wave, and video analytics technologies for detecting person-borne improvised explosive devices at a public arena. The test results are being used to develop a concept for the next generation of integrated countermeasures, to refine technical and operational requirements for architectures and technologies, and engage industry and academia in solution development.

    Mexico has entered in an important dynamic of structural changes in the energy area, proof of this, it is the Energy Reform 2013 and the Energy Transition Law published the last December 24th, 2015, thus it is important to carry out studies of the impacts of future politics in the consumption of the population, so this study estimate an energy demand system using microdata collected from 97,817 households in a National Households Income and Expenditure Survey (ENIGH acronyms in Spanish, Encuesta Nacional de Ingresos y Gastos de los Hogares) in the 20-years period from 1994 to 2014. The magnitudes of all the fuels are smaller than one indicating that electricity, LPG, gasoline and public transport are normal goods, while LPG is the most inelastic energy source. The geographic factor shows that households in the north of Mexico tend to consume more gasoline, whereas in the south of the country, the lowest share of LPG expenditure is reported. The rigorous evaluation of energy demanded in households will help policy makers to put forward more efficient reforms. - Highlights: • The electricity, LPG, gasoline and public transport are normal goods. • LPG is the most inelastic energy source. • The north of Mexico tend to consume more gasoline. • Evidence of complement between personal vehicle and public transport.

    Since 1993, following the National Thalassemia Major Prevention Program and an increase in immigration and interracial marriages, especially in southern Taiwan, the distribution of hemoglobinopathies may have changed. This study investigates the epidemiologic transition of hemoglobinopathies. We analyzed 1870 specimens collected between 2003 and 2012 in southern Taiwan, used gap-polymerase chain reaction and PCR-restriction fragment length polymorphism-based methods, and confirmed genotypes of hemoglobinopathies by DNA sequencing. We found a 91% reduction in the incidence of thalassemia major compared with samples from between 1986 and 1995. The most common genotypes of α-thalassemia and α Hb variants were the SEA type (69.4%) and Hb Quong Sze (1.54%). The most common genotypes of β-thalassemia and β Hb variants were IVS-II-654 (46.2%) and Hb E (2.2%), respectively. Compared with studies performed in different areas of and time intervals in Taiwan, a higher prevalence of -α 3.7 , Hb Quong Sze, and Hb E and a lower prevalence of the SEA type were found in this study. However, the SEA type remained the most common genotype observed. In addition, an increasing number of cases with an -α 3.7 type carrier, Hb Quong Sze carrier, and G γ (A γ δβ)° were identified following a peak of interracial marriages between 2003 and 2005, reflecting a regional difference and the impact of interracial marriage. In conclusion, global migration and international marriage have changed the distribution of hemoglobinopathies in Taiwan. A more comprehensive prenatal screening for new immigrants with a longer follow-up is warranted.

    NASA, at the John F. Kennedy Space Center (KSC), developed and operates a unique high precision lightning location system to provide lightning related weather warnings. These warnings are used to stop lightning-sensitive operations such as space vehicle launches and ground operations where equipment and personnel are at risk. The data is provided to the Range Weather Operations [45th Weather Squadron, U. S. Air Force (USAF)] where it is used with other meteorological data to issue weather advisories and warnings for Cape Canaveral Air Station (CCAS) and KSC operations. This system, called Lightning Detection and Ranging (LDAR), provides users with a graphical display in three dimensions of 66 MHz radio frequency events generated by lightning processes. The locations of these events provide a sound basis for the prediction of lightning hazards. NASA and Global Atmospherics, Inc. are developing a new system that will replace the unique LDAR components with commercially available and maintainable components having improved capabilities. These components will be phased in to ensure full continuity and access to this important warning technology. These LDAR systems are expected to eventually be available for installation and use by the public at specialized facilities, such as airports, and for general weather warnings via the National Weather Service (NWS) or television broadcast. The NWS in Melbourne has had access to real-time LDAR data since 1993 on an experimental basis. This use of LDAR has shown promise for the improvement of aviation forecasts and severe weather warnings. More so, it has opened the door to investigate the feasibility of issuing lightning-related public advisories. The success of its early use suggests that this technology may improve safety and potentially save lives, therefore constituting a significant benefit to the public. This paper describes the LDR system, the plans and progress of these upgrades, and the potential benefits of its use.

    In spite of the high prevalence of tuberculosis worldwide, there are only a few studies on its psychiatric complications such as suicidal behaviour. We undertook this study to assess the prevalence of suicidal behaviour and its associated factors among tuberculosis patients in public primary care in South Africa. In a cross-sectional survey conducted in three provinces of South Africa new TB and new re-treatment patients were assessed within one month of anti-tuberculosis treatment. The sample included 4900 (54.5% men and women 45.5%) consecutively selected tuberculosis patients from 42 public primary care clinics in three districts in South Africa. A total of 322 patients (9.0%) reported suicidal ideation and 131 (3.1%) had a history of a suicide attempt. In multivariate analysis female gender [Odds Ratio (OR)= 0.56, Confidence Interval (CI)= 0.43-0.74], psychological distress (OR=2.36, CI=1.04-2.29), post-traumatic stress disorders (PTSD) (OR=4.98, CI=3.76-6.59), harmful alcohol use (OR=1.97, CI=1.25-3.09) and being a TB re-treatment patient (OR=1.76, CI=1.32-2.34) were associated with suicidal ideation, and psychological distress (OR=3.27, CI=1.51-7.10), PTSD symptoms (OR=4.48, CI=3.04-6.61) and harmful alcohol use (OR=3.01, CI=1.83-4.95) were associated with a suicide attempt. Our findings suggest that co-morbid illnesses of psychological distress, PTSD and harmful alcohol use and HIV infection should be assessed in TB patients under TB control programmes to prevent suicidal behaviour. Clinicians should be aware about suicidality in tuberculosis patients to reduce mortality.

    2017-09-01

    Full Text Available From the general positions of population dynamics, the demographic policy is considered, its regional features in the East of Russia are designated. It is necessary to consolidate the positive traditions of the moral and legal norms of the society and the harmonious personality development. It takes their long-term translation for the improvement of the person himself, his family-marriage relations to support the forms of demographic behavior aimed at the expanded population reproduction. The solution of the numerous tasks of the demographic policy presupposes further scientific (theoretical and applied studies of the features of the socio-demographic and medico-demographic development of the Russian regions. Particular attention should be paid to the analysis of the main characteristics of the epidemiological transition, where mortality, as well as birth rate, is one of the main characteristics of the population reproduction. This will make it possible to define more precisely the prediction of the value of irretrievable losses with endogenous and exogenous determination, to estimate on this basis the reserves of increasing life expectancy through the measures of demographic policy.

    2011-01-01

    One of the most important challenges in addressing global health is for institutions to monitor and use research in policy-making. In low- and middle-income countries (LMICs), civil society organizations such as health professional associations can be key contributors to effective national health systems. However, there is little empirical data on their capacity to use research. This case study was used to gain insight into the factors that affect the knowledge translation performance of health professional associations in LMICs by describing the organizational elements and processes constituting capacity to use research, and examining the potential determinants of this capacity. Case study methodology was chosen for its flexibility to capture the multiple and often tacit processes within organizational routines. The Burkina Faso Public Health Association (ABSP) was studied, using in-depth, semi-structured interviews and key documents review. Five key dimensions that affect the association's capacity to use research to influence health policy emerged: organizational motivation; catalysts; organizational capacity to acquire and organizational capacity to transform research findings; moderating organizational factors. Also examined were the dissemination strategies used by ABSP and its abilities to enhance its capacity through networking, to advocate for more relevant research and to develop its potential role as knowledge broker, as well as limitations due to scarce resources. We conclude that a better understanding of the organizational capacity to use research of health professional associations in LMICs is needed to assess, improve and reinforce such capacity. Increased knowledge translation potential may leverage research resources and promote knowledge-sharing. Copyright © 2010 Elsevier Ltd. All rights reserved.

    The menopausal transition is associated with somatic symptoms and increased rates of depression, which can impair quality of life (QOL) and increase cardiovascular disease (CVD) risk. This period is also associated with accelerated vascular aging (arterial stiffening and endothelial dysfunction), an antecedent to CVD. This secondary analysis sought to explore associations between depression, menopausal symptoms and QOL, and vascular aging across menopause stages. Arterial stiffness (carotid artery compliance), endothelial function (brachial artery flow-mediated dilation [FMD]), menopausal symptoms (Menopausal Symptom List [MSL]), depression (Center for Epidemiologic Studies Depression Scale [CES-D]), and QOL (Utian QOL Scale [UQOL]) were measured in 138 women (19-70 years) classified as premenopausal (n = 41, 34 ± 8 years; mean ± SD), early (n = 25, 49 ± 3 years), or late perimenopausal (n = 26, 50 ± 4 years), or early (n = 22, 55 ± 4 years) or late postmenopausal (n = 24, 61 ± 5 years). Differences across menopause stages were determined using one-way analysis of variance; associations between vascular measures and MSL, CES-D, and UQOL were tested using Pearson's correlation analyses. Menopausal symptoms, depression, and QOL worsened across menopause stages, particularly in late perimenopausal women. Vasosomatic symptom frequency, and general somatic symptom frequency and severity were inversely correlated with carotid artery compliance and FMD (r = -0.27 to -0.18, all P stages of menopause was associated with greater frequency and severity of menopausal symptoms, and lower QOL, but not depression. Mechanisms underlying these associations (eg, inflammation, oxidative stress) should be explored.

    We imaged the SiO maser emission of J=5-4 in the v=1 state associated with the peculiar red supergiant VY Canis Majoris using the partially completed Submillimeter Array. We identified seven maser components and measured the relative positions at sub-arcsecond scale in the high J transition for the first time. We have also measured the polarization of these maser components. The strongest maser feature has a linear polarization of ˜ 60%, and its direction of polarization is approximately aligned with the bipolar axis. Such a high degree of polarization suggests that radiative pumping is probably responsible for the maser inversion. Five of the other maser features have significant linear polarization.

    The role of stellar age in the measured properties and occurrence rates of exoplanets is not well understood. This is in part due to a paucity of young planets and the uncertainties in age-dating for most exoplanet host stars. Exoplanets belonging to coeval stellar populations, young or old, are particularly useful as benchmarks for studies aiming to constrain the evolutionary timescales relevant for planets. Such timescales may concern orbital migration, gravitational contraction, or photo-evaporation, among other mechanisms. Here we report the serendipitous discovery of a transiting sub-Neptune from K2 photometry of a K-type star that is a new candidate member of the nearby young Cas-Tau association. The size of the planet (3.0 +/- 0.5 Earth radii) and its age (~50-90 Myr) make it an intriguing test case for photo-evaporation models, which predict enhanced atmospheric mass loss during early evolutionary stages.

    This study aimed to better understand the current situation of risk assessment and identify the factors associated with competence of emergency responders in public health risk assessment. The participants were selected by a multi-stage, stratified cluster sampling method in Heilongjiang Centers for Disease Control and Prevention (CDC). The questionnaires that measured their perceptions on risk assessment competences were administered through the face-to-face survey. A final sample of 1889 staff was obtained. Of this sample, 78.6% of respondents rated their own risk assessment competences as "relatively low", contrasting with 21.4% rated as "relatively high". Most of the respondents (62.7%) did not participate in any risk assessment work. Only 13.7% and 42.7% of respondents reported participating in risk assessment training and were familiar with risk assessment tools. There existed statistical significance between risk assessment-related characteristics of respondents and their self-rated competences scores. Financial support from the government and administrative attention were regarded as the important factors contributing to risk assessment competences of CDC responders. Higher attention should be given to risk assessment training and enhancing the availability of surveillance data. Continuous efforts should be made to remove the financial and technical obstacles to improve the competences of risk assessment for public health emergency responders.

    We examined whether public schools in states with specific and stringent physical education (PE) laws, as assessed by the Physical Education-Related State Policy Classification System (PERSPCS), available on the Classification of Laws Associated with School Students (C.L.A.S.S.) Web site, reported more weekly PE time in the most recent School Health Policies and Programs Survey (SHPPS). Schools (n=410) were grouped by their state's PERSPCS time requirement scores (none, nonspecific requirement, or specific requirement). Average weekly school-level PE was calculated using the SHPPS-reported PE minutes. Weighted analyses determined if PE minutes/week differed by PERSPCS group. Schools in states with specific requirement laws averaged over 27 and 60 more PE minutes/week at the elementary and middle school levels, respectively, compared with schools within states with nonspecific laws and over 40 and 60 more PE minutes per week, respectively, compared with elementary and middle schools in states with no laws. High school results were nonsignificant. Public health guidelines recommend at least 60 minutes of daily physical activity for children, and PE may further this goal. Strong codified law with specific time requirements for PE may be an important tool contributing toward adequate PE time and daily physical activity recommendations.

    The Organic Act of 1879 (43 USC 31) that established the US Geological Survey provided, among other things, for the classification of the public lands and for the examination of the geological structure, mineral resources, and products of the national domain. In order to provide uniform executive action in classifying public lands, standards for determining which lands are valuable for mineral resources, for example, leasable mineral lands, or for other products are prepared by the US Geological Survey. This report presents the classification standards for determining which Federal lands are classifiable as geothermal steam and associated geothermal resources lands under the Geothermal Steam Act of 1970 (84 Stat. 1566). The concept of a geothermal resouces province is established for classification of lands for the purpose of retention in Federal ownership of rights to geothermal resources upon disposal of Federal lands. A geothermal resources province is defined as an area in which higher than normal temperatures are likely to occur with depth and in which there is a resonable possiblity of finding reservoir rocks that will yield steam or heated fluids to wells. The determination of a known geothermal resources area is made after careful evaluation of the available geologic, geochemical, and geophysical data and any evidence derived from nearby discoveries, competitive interests, and other indicia. The initial classification required by the Geothermal Steam Act of 1970 is presented.

    Full Text Available Objectives: Drug injection carries with it many risks and therefore it is important to understand the initiating factors of injection and its origins. Thus,  the purpose of this study was to identify factors associated with the initiation of injection drug use among substance abusers. Methods:  Study method was a cross-sectional study. The research statistics universe constitutes all people suffering from a substance dependence disorder with a pattern of injection use in Tehran and Hamedan. This study was conducted among 216 individuals with substance dependence disorders who were selected from harm reduction centers in Tehran and Hamedan. The sampling selection method was simply random. The instruments used for data collection included: demographic information, patterns of drug use and initiation of injection scales.  Results: In this study, the average age of initiation to injections was 22.5 years. Factors associated with initiation of drug injection included: acquired more pleasure, easier use, faster effect of injection, ineffective previous use method, curiosity, peer pressure, lack of availability of the drug, poverty, and low quality drugs. Discussion: Results of this study indicate that initiation factors to drug injection are multifaceted (Psychological, Social, Economic and Environmental, therefore, injection interventionists should consider all these factors for prevention, treatment and harm reduction.

    For the last 15 years, infection from Helicobacter pylori (H. pylori) has been recognized in gastritis pathogenesis, and is known to trigger an important inflammatory response in these patients. To determine the association between follicular gastritis and H. pylori infection in children seen at a public hospital in Peru. An analytic, cross-sectional study was conducted on all the children treated at the Hospital Nacional Docente Madre "Niño San Bartolomé" in Lima, Peru, within the time frame of 2011-2012. All the personal data from the patients' medical histories and endoscopic procedures were collected. The crude prevalence ratios (PR) were obtained and adjusted (aPR) with their 95% confidence intervals (95%CI), using generalized linear models with the binomial family and log link function. A total of 123 children met the study criteria. Forty-eight (39%) of the study sample were girls and the mean age of the children was 12 years. H. pylori was present in 44% of the sample and 9% presented with more than 100 bacteria per field (classified as +++). Thirty-five percent of the children had esophagitis due to concomitant reflux. The presence of H. pylori was associated with follicular gastritis (Pgastritis had a greater likelihood of having H. pylori than those that did not present with gastritis. These results can be extrapolated to other similar populations and should be evaluated in each setting so that this does not become a public health problem within the next few years.

    Health professionals' motivation reflects the interaction between health professionals and their work environment. It can potentially affect the provision of health services; however, this important attribute of the workplace climate in public hospitals is not usually given serious attention to the desired level. For this reason, the authors of this study have assessed the level of motivation of health professionals and associated factors in public hospitals of West Amhara, Northwest Ethiopia. A facility based cross-sectional study was conducted in eight public hospitals of West Amhara from June 1 to July 30, 2013. A total of 304 health professionals were included in this study. The collected data were analyzed using SPSS software version 20. The reliability of the instrument was assessed through Cronbach's α. Factor scores were generated for the items found to represent the scales (eigenvalue greater than one in varimax rotation) used in the measurement of the variables. The scores were further analyzed using one-way analysis of variance, t-tests, Pearson's correlation, and hierarchical multiple linear regression analyses. The cut-off point for the regression analysis to determine significance was set at β (95% confidence interval, Pmotivation scores (as the percentage of maximum scale scores) were 58.6% for the overall motivation score, 71.0% for the conscientiousness scale, 52.8% for the organizational commitment scale, 58.3% for the intrinsic motivation scale, and 64.0% for organizational burnout scale. Professional category, age, type of the hospital, nonfinancial motivators like performance evaluation and management, staffing and work schedule, staff development and promotion, availability of necessary resources, and ease of communication were found to be strong predictors of health worker motivation. Across the hospitals and professional categories, health workers' overall level of motivation with absolute level of compensation was not significantly

    Ecological opportunity is often regarded as a key factor that explains why diversity is unevenly distributed across life. Colonization of novel environments or adaptive zones may promote diversification. North American minnows exhibit an ancestral benthic-to-pelagic habitat shift that coincided with a burst in diversification. Here, we evaluate the phenotypic and ecological implications of this habitat shift by assessing craniofacial and dietary traits among 34 species and testing for morphology-diet covariation, convergence and adaptive optima. There were several instances of morphology-diet covariation such as correlations between mouth angle and the consumption of terrestrial insects and between relative gut length and the consumption of algae. After accounting for size and phylogenetic nonindependence, benthic species had longer heads, longer snouts, eyes positioned higher on their head, smaller mouth angles and longer digestive tracts than pelagic minnows. Benthic minnows also consumed more algae but less terrestrial insects, by volume, than pelagic minnows. Lastly, there were three distinct evolutionary regimes and more convergence in morphology and dietary characteristics than expected under a Brownian motion model of evolution. These findings indicate that colonization of the pelagic zone by minnows involved myriad phenotypic and dietary changes associated with exploitation of terrestrial subsidies. Thus, minnows exhibit phenotype-dietary covariation, an expansion of ecological roles and a burst in diversification rates in response to the ecological opportunity afforded by the colonization of a novel habitat. © 2016 European Society For Evolutionary Biology.

    To determine the epidemiological profile of gestational syphilis and associated factors in a Peruvian population. The study is a secondary analysis of data obtained from public hospitals in Peru for the 2000-2010 period. 652,636 pregnant women were included from 37 cities and 45 health centers in Peru. The prevalence of gestational syphilis was 0.7%, while 80.7% reported screening for gestational syphilis. The highest prevalence of maternal syphilis is found in the lowland rainforest followed by the highland rainforest. In the three regions of Peru decreased prevalence of gestational syphilis has been seen throughout the years. The prevalence for 2010 are 0.2% on the coast, in the highlands 0.23% and 0.47% in the jungle. The lack of education and prenatal care, high parity, cohabiting or single, and living in the jungle, are associated with having a positive syphilis test. The results suggests that prevalence of gestational syphilis has declined over the decade 2000-2010.

    A continuous rise in the rate of cesarean deliveries has been reported in many countries over recent decades. This trend has prompted the emergence of a debate on the risks and benefits associated with cesarean section. The present study was designed to estimate cesarean section rates over time during the period between 2000 and 2010 in Peru and to present outcomes for each mode of delivery. This is a secondary analysis of a large database obtained from the Perinatal Information System, which includes 570,997 pregnant women and their babies from 43 Peruvian public health facilities in three geographical regions: coast, highlands, and jungle. Over 10 years, 558,901 women delivered 563,668 infants weighing at least 500 g. The cesarean section rate increased from 25.5% in 2000 to 29.9% in 2010 (26.9% average; P cesarean than vaginal deliveries (P cesarean section (P cesarean section group than in the vaginal delivery group. Data suggest that cesarean sections are associated with adverse pregnancy outcomes. PMID:24124393

    To assess whether conference abstracts that report higher estimates of diagnostic accuracy are more likely to reach full-text publication in a peer-reviewed journal. We identified abstracts describing diagnostic accuracy studies, presented between 2007 and 2010 at the Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting. We extracted reported estimates of sensitivity, specificity, area under the receiver operating characteristic curve (AUC), and diagnostic odds ratio (DOR). Between May and July 2015, we searched MEDLINE and EMBASE to identify corresponding full-text publications; if needed, we contacted abstract authors. Cox regression was performed to estimate associations with full-text publication, where sensitivity, specificity, and AUC were logit transformed, and DOR was log transformed. A full-text publication was found for 226/399 (57%) included abstracts. There was no association between reported estimates of sensitivity and full-text publication (hazard ratio [HR] 1.09 [95% confidence interval {CI} 0.98, 1.22]). The same applied to specificity (HR 1.00 [95% CI 0.88, 1.14]), AUC (HR 0.91 [95% CI 0.75, 1.09]), and DOR (HR 1.01 [95% CI 0.94, 1.09]). Almost half of the ARVO conference abstracts describing diagnostic accuracy studies did not reach full-text publication. Studies in abstracts that mentioned higher accuracy estimates were not more likely to be reported in a full-text publication. Copyright © 2016 Elsevier Inc. All rights reserved.

    Prescription opioid use disorder and overdose have emerged as significant public health challenges in the past 15 years. Little is known about public attitudes toward individuals who have developed a prescription opioid use disorder and whether these attitudes affect support for policy interventions. This study examined social stigma toward individuals with prescription opioid use disorder and tested whether stigma was associated with support for various policy interventions. A nationally representative Web-based survey was conducted from January 31 to February 28, 2014. The 1,071 respondents reported on their beliefs about and attitudes toward persons affected by prescription opioid use disorder and rated their support for various policy interventions. Ordered logistic regression models estimated the association between stigma and public support for punitive and public health-oriented policies. Most respondents viewed this disorder as affecting all groups-racial and ethnic, income, and geographic area of residence groups-fairly equally, despite epidemiological data demonstrating that certain populations have been disproportionately burdened. Respondents expressed high levels of stigma toward individuals with prescription opioid use disorder. Levels of stigma were generally similar among those with and without experience with prescription opioid use disorder, either one's own or that of a relative or close friend. Higher levels of stigma were associated with greater support for punitive policies and lower support for public health-oriented policies. Reframing the issue to emphasize the structural factors contributing to prescription opioid use disorder and the barriers to accessing evidence-based treatment might improve support for policies that benefit affected individuals.

    To identify the prevalence of body image dissatisfaction and associated factors among students in Salvador, Brazil. A cross-sectional study involving a random sample of 1,494 (852 girls and 642 boys) adolescents between 11 and 17 years of age who were students in the public schools in Salvador, Brazil. Participants completed the Body Shape Questionnaire and the Eating Attitudes Test-26. Body image was characterized as satisfactory or unsatisfactory. We obtained demographic, anthropometric and economic information and information regarding the stage of maturation, self-perception of body weight, and consumption of sweetened beverages and diet soft drinks. To identify associated factors we used Poisson regression analysis. Body image dissatisfaction was present in 19.5% of the adolescents, with a prevalence of 26.6% among the girls and 10% among the boys. Independent of sex, the prevalence of body image dissatisfaction was higher among adolescents who were overweight or obese (girls, PR: 1.38, CI: 1.09-1.73 and boys, PR: 2.26, CI: 1.08-4.75), higher among those who perceived themselves as fat (girls, PR: 2.85, CI: 2.07-3.93 and boys, PR: 3.17, CI: 1.39-7.23), and higher among those who had negative attitudes toward eating (girls, PR: 2.42, CI: 1.91-3.08 and boys, PR: 4.67, CI: 2.85-7.63).. A reduction in body image dissatisfaction was only identified among underweight girls (PR: 0.12, CI: 0.03-0.49). A high occurrence of body image dissatisfaction was observed among the adolescents, and biological and behavioral factors were associated with this dissatisfaction.

    To better interpret previously described hormonal changes observed during the natural postweaning fast (2-3 months) endured by pups of the northern elephant seal (Mirounga angustirostris), we compared plasma cortisol, thyroid hormones, and leptin in pups (n=5) measured during nursing and fasting periods. Blood samples were taken at four times; early (9 days postpartum) and late (18-22 days postpartum) nursing, and early (second week postweaning) and late (eighth week postweaning) fasting. Plasma cortisol increased 39% between early and late nursing and almost 4-fold by late fasting. After the early nursing period, cortisol and body mass were negatively correlated (y=28.3-0.19 x; R=0.569; p=0.027). Total thyroxine (tT(4)), free T(4) (fT(4)), total triiodothyronine (tT3) and reverse T(3) (rT(3)) were greatest at early nursing and reduced by late nursing and remained so throughout the fast, with the exception of tT(4), which increased between late nursing (17.7+/-2.1 ng mL(-1)) and late fasting (30.1+/-2.8 ng mL(-1)) periods. Leptin remained unaltered among the four sampling periods and was not correlated with body mass. Pups appear to exhibit a shift in the relationship between cortisol and body mass suggesting a potential role for cortisol in the regulation of body fat. The higher concentrations of tT(3) and tT(4) during early nursing may reflect enhanced growth and development during this period, however the increase late in fasting is likely physiologically insignificant and an artifact of reduced metabolic clearance of these hormones. Transition of the pups from nursing to fasting states is characterized by a striking lack of change in cortisol, thyroid hormones, and leptin suggesting that any metabolic alterations associated with this transition may occur independent of these hormones.

    The study investigated associations of Slovene emerging adults' age, gender, living situation, romantic relationship, and employment status with aspects of individuation in relation to mother and father. Controlling for demographic variables and transitional markers of adulthood, we further explored the contribution of individuation measures to individuals' perceptions of achieved criteria for adulthood and life satisfaction. The participants provided self-reports on the Individuation Test for Emerging Adults, the Satisfaction With Life Scale, and the list of Achieved Criteria for Adulthood. Age and living out of parental home were positively associated with self-reliance in relation to both parents, whereas female gender was related to higher levels of connectedness and seeking parental support. Along with age and involvement in a romantic relationship, connectedness and self-reliance predicted adulthood criteria attainment and life satisfaction. The results support the models of individuation that emphasize growing autonomy and retaining connectedness to parents as pathways towards personal adjustments.

    In Kenya, cancers as a disease group rank third as a cause of death after infectious and cardiovascular diseases. It is estimated that the annual incidence of cancer is about 37,000 new cases with an annual mortality of 28,000 cases (Kenya National Cancer Control Strategy 2010). The incidence of non-communicable diseases accounts for more than 50% of total hospital admissions and over 55% of hospital deaths (Kenya National Strategy for the Prevention and Control of Non Communicable Diseases 2015-2020). The prevalence of HIV is 6.8 (KIAS 2014). Most of these patients will benefit from palliative care services, hence the need to integrate palliative care services in the public healthcare system. The process of integrating palliative care in public hospitals involved advocacy both at the national level and at the institutional level, training of healthcare professionals, and setting up services within the hospitals that we worked with. Technical support was provided to each individual institution as needed. Eleven provincial hospitals across the country have now integrated palliative care services (Palliative Care Units) and are now centres of excellence. Over 220 healthcare providers have been trained, and approximately, over 30,000 patients have benefited from these services. Oral morphine is now available in the hospital palliative care units. As a success of the pilot project, Kenya Hospices and Palliative Care Association (KEHPCA) is now working with the Ministry of Health Kenya to integrate palliative care services in 30 other county hospitals across the country, thus ensuring more availability and access to more patients. Other developing countries can learn from Kenya's successful experience.

    Increased taxation on tobacco products is an effective method of reducing tobacco use. This study assessed population support among respondents aged ≥15 years, from 27 European Union (EU) countries for increased taxation and other tobacco control measures during the 2009-2012 period. Nationally representative data were obtained from the 2009 (n=26,788) and 2012 (n=26,751) cross-sectional Eurobarometer surveys. Estimates were compared using chi-square statistics. The effect of the relative change in gross domestic product (GDP) on the change in support for increased taxation during 2009-2012 was calculated using the Pearson correlation coefficient and linear regression models. Between 2009 and 2012, population support for increased taxes on tobacco products declined (56.1% to 53.2%; p<0.001). However, support for other tobacco control measures increased significantly. After adjusting for baseline GDP per capita (2009), a 10% increase in GDP per capita was associated with 4.5% increase in support of tax increases. When Latvia and Lithuania were excluded from the analyses (because of their marked deviation from the general trend), there was a strong correlation between the change in GDP and support for increased taxes (ρ=0.64; p<0.001). Also, after adjusting for baseline GDP, support for higher taxes on tobacco increased by 7.0% for every 10% increase in GDP between 2009 and 2012. Population support for tax increases declined in the EU between 2009 and 2012, especially in countries with declines in GDP nonetheless, public support for other tobacco control measures remains high, thus indicating a viable environment for more comprehensive tobacco control. © 2014 the Nordic Societies of Public Health.

    The objective of this study is to establish the prevalence of dysphonia and associated factors in public school female teachers working in Belo Horizonte. This cross-sectional study was conducted on a random sample of schools between May 2004 and July 2005. There were 2103 elementary education daytime teachers from 83 schools included in the study. Self-applied questionnaires were used for data collection. These included questions on social and demographic matters, general health and mental health (General Health Questionnaire-12 [GHQ-12]), the environment and organization of work, and voice-related aspects. The variable dysphonia was classified as absent, possible, or probable based on the association between frequency of fatigue when speaking and worsened voice quality during the past 15 days. Multinomial logistic regression was used to analyze factors independently associated with dysphonia in each response subgroup and in total. One third of the female teachers did not report voice symptoms during the past 15 days (33%). The prevalence of probable dysphonia was 15%, and the prevalence for possible dysphonia was 52%. Factors associated with probable dysphonia were presence of recent upper airway problems (odds ratio [OR]=5.95, 95% confidence interval [CI]=4.06-8.71), problems at work because of voice (OR=65.30, 95% CI=19.33-220.59), other activities with intense voice use (OR=1.71, 95% CI=1.08-2.71), high noise levels (OR=2.55, 95% CI=1.72-3.76), poor ventilation in the classroom (OR=2.00, 95% CI=1.24-3.22), current mental disorder (OR=3.20, 95% CI=2.18-4.70), sedentary life style (OR=1.94, 95% CI=1.21-3.09), and marriage (OR=1.70, 95% CI=1.16-2.47). Associations between probable dysphonia, poor working conditions, health-related aspects, and professional jeopardy indicate the complexity of dysphonia in female teachers and the need for collective intervention strategies.

    Lyophilized proteins are generally stored below their glass transition temperature (T g ) to maintain long-term stability. Some proteins in the (pure) solid state showed a distinct endotherm at a temperature well below the glass transition, designated as a pre-T g endotherm. The pre-T g endothermic event has been linked with a transition in protein internal mobility. The aim of this study was to investigate the internal dynamics of 2 proteins, insulin and human growth hormone (hGH), both of which exhibit the pre-T g endothermic event with onsets at 50°C-60°C. Solid state hydrogen/deuterium (H/D) exchange of both proteins was characterized by Fourier transform infrared spectroscopy over a temperature range from 30°C to 80°C. A distinct sigmoidal transition in the extent of H/D exchange had a midpoint of 56.1 ± 1.2°C for insulin and 61.7 ± 0.9°C for hGH, suggesting a transition to greater mobility in the protein molecules at these temperatures. The data support the hypothesis that the pre-T g event is related to a transition in internal protein mobility associated with the protein dynamical temperature. Exceeding the protein dynamical temperature is expected to activate protein internal motion and therefore may have stability consequences. Copyright © 2016 American Pharmacists Association®.

    This study examines psychophysiological and subjective reactivity to anxiety-provoking situations in relation to social anxiety and public speaking fear. We hypothesized that social anxiety symptoms would be associated with similar reactivity across types of imaginary anxiety scenes and not specifically to social anxiety-related scenes. This would be attributed to co-existing depression symptoms. Public speaking fear was expected to be associated with more circumscribed reactivity to survival-threat scenes, due to its association with fearfulness. Community participants imagined standardized anxiety situations, including social anxiety and animal fear scenes, while their physiological reactivity and self-reported emotions were assessed. Findings supported that social anxiety was associated with undifferentiated physiological reactivity across anxiety-provoking situations, except with regards to skin conductance level, which was higher during social anxiety imagery. Public speaking fear was associated with increased reactivity to animal phobia and panic scenes. Covariance analyses indicated that the lack of response specificity associated with social anxiety could be attributed to depression levels, while the specificity associated with public speaking fear could be explained by fearfulness. Findings highlight the need to assess not only primary anxiety symptoms but also depression and fearfulness, which likely predict discrepant reactions of individuals to anxiogenic situations.

  11. The Disintegrin and Metalloprotease ADAM12 Is Associated with TGF-β-Induced Epithelial to Mesenchymal Transition.

    Directory of Open Access Journals (Sweden)

    Michaël Ruff

    Full Text Available The increased expression of the Disintegrin and Metalloprotease ADAM12 has been associated with human cancers, however its role remain unclear. We have previously reported that ADAM12 expression is induced by the transforming growth factor, TGF-β and promotes TGF-β-dependent signaling through interaction with the type II receptor of TGF-β. Here we explore the implication of ADAM12 in TGF-β-mediated epithelial to mesenchymal transition (EMT, a key process in cancer progression. We show that ADAM12 expression is correlated with EMT markers in human breast cancer cell lines and biopsies. Using a non-malignant breast epithelial cell line (MCF10A, we demonstrate that TGF-β-induced EMT increases expression of the membrane-anchored ADAM12L long form. Importantly, ADAM12L overexpression in MCF10A is sufficient to induce loss of cell-cell contact, reorganization of actin cytoskeleton, up-regulation of EMT markers and chemoresistance. These effects are independent of the proteolytic activity but require the cytoplasmic tail and are specific of ADAM12L since overexpression of ADAM12S failed to induce similar changes. We further demonstrate that ADAM12L-dependent EMT is associated with increased phosphorylation of Smad3, Akt and ERK proteins. Conversely, inhibition of TGF-β receptors or ERK activities reverses ADAM12L-induced mesenchymal phenotype. Together our data demonstrate that ADAM12L is associated with EMT and contributes to TGF-β-dependent EMT by favoring both Smad-dependent and Smad-independent pathways.

    Variations in physical activity (PA) across nations may be driven by socioeconomic position. As national incomes increase, car ownership becomes within reach of more individuals. This report characterizes associations between car ownership and PA in African-origin populations across 5 sites at different levels of economic development and with different transportation infrastructures: US, Seychelles, Jamaica, South Africa, and Ghana. Twenty-five hundred adults, ages 25-45, were enrolled in the study. A total of 2,101 subjects had valid accelerometer-based PA measures (reported as average daily duration of moderate to vigorous PA, MVPA) and complete socioeconomic information. Our primary exposure of interest was whether the household owned a car. We adjusted for socioeconomic position using household income and ownership of common goods. Overall, PA levels did not vary largely between sites, with highest levels in South Africa, lowest in the US. Across all sites, greater PA was consistently associated with male gender, fewer years of education, manual occupations, lower income, and owning fewer material goods. We found heterogeneity across sites in car ownership: after adjustment for confounders, car owners in the US had 24.3 fewer minutes of MVPA compared to non-car owners in the US (20.7 vs. 45.1 minutes/day of MVPA); in the non-US sites, car-owners had an average of 9.7 fewer minutes of MVPA than non-car owners (24.9 vs. 34.6 minutes/day of MVPA). PA levels are similar across all study sites except Jamaica, despite very different levels of socioeconomic development. Not owning a car in the US is associated with especially high levels of MVPA. As car ownership becomes prevalent in the developing world, strategies to promote alternative forms of active transit may become important.

    Methodological research has found that non-published studies often have different results than those that are published, a phenomenon known as publication bias. When results are not published, or are published selectively based on the direction or the strength of the findings, healthcare professionals and consumers of healthcare cannot base their decision-making on the full body of current evidence. As part of the OPEN project (http://www.open-project.eu) we will conduct a systematic review with the following objectives:1. To determine the proportion and/or rate of non-publication of studies by systematically reviewing methodological research projects that followed up a cohort of studies that a. received research ethics committee (REC) approval,b. were registered in trial registries, orc. were presented as abstracts at conferences.2. To assess the association of study characteristics (for example, direction and/or strength of findings) with likelihood of full publication.To identify reports of relevant methodological research projects we will conduct electronic database searches, check reference lists, and contact experts. Published and unpublished projects will be included. The inclusion criteria are as follows:a. RECs: methodological research projects that examined the subsequent proportion and/or rate of publication of studies that received approval from RECs;b.

    2013-01-01

    Background In recent decades, the general public has become increasingly receptive toward a legislation that allows active voluntary euthanasia (AVE). The purpose of this study was to survey the current attitude towards AVE within the Austrian population and to identify explanatory factors in the areas of socio-demographics, personal experiences with care, and ideological orientation. A further objective was to examine differences depending on the type of problem formulation (abstract vs. situational) for the purpose of measuring attitude. Methods A representative cross-sectional study was conducted across the Austrian population. Data were acquired from 1,000 individuals aged 16 years and over based on telephone interviews (CATI). For the purpose of measuring attitude toward AVE, two different problem formulations (abstract vs. situational) were juxtaposed. Results The abstract question about active voluntary euthanasia was answered negatively by 28.8%, while 71.2% opted in favour of AVE or were undecided. Regression analyses showed rejection of AVE was positively correlated with number of adults and children in the household, experience with care of seriously ill persons, a conservative worldview, and level of education. Mean or high family income was associated with lower levels of rejection. No independent correlations were found for variables such as sex, age, political orientation, self-rated health, and experiences with care of terminally ill patients. Correlation for the situational problem formulation was weaker and included fewer predictors than for the abstract question. Conclusions Our results suggest that factors relating to an individual’s interpersonal living situation and his/her cognitive convictions might be important determinants of the attitude toward AVE. If and to the extent that personal care experience plays a role, it is rather associated with rejection than with acceptance of AVE. PMID:23826902

This trend has prompted the emergence of a debate on the risks and benefits associated with cesarean section. The present study was designed to estimate cesarean section rates over time during the period between 2000 and 2010 in Peru and to present outcomes for each mode of delivery. This is a secondary analysis of a large database obtained from the Perinatal Information System, which includes 570,997 pregnant women and their babies from 43 Peruvian public health facilities in three geographical regions: coast, highlands, and jungle. Over 10 years, 558,901 women delivered 563,668 infants weighing at least 500 g. The cesarean section rate increased from 25.5% in 2000 to 29.9% in 2010 (26.9% average; P < 0.01. The rate of stillbirths was lower with cesarean than vaginal deliveries (P < 0.01. On the other hand, and as expected, the rates for preterm births, twin pregnancies, and preeclampsia were higher in women who delivered by cesarean section (P < 0.01. More importantly, the rate of maternal mortality was 5.5 times higher in the cesarean section group than in the vaginal delivery group. Data suggest that cesarean sections are associated with adverse pregnancy outcomes.Keywords: elective cesarean, emergency cesarean, geographical regions, cesarean rates over time, adverse outcomes, developing country

    Full Text Available Introduction. Globally, depression is one of the three leading causes of disease and it will be the second leading cause of world disability by 2030. The prevalence of depression in Sub-Saharan Africa ranges from 15 to 30%. In Ethiopia, depression was found to be the seventh leading cause of disease burden and its prevalence has been increased in hospital compared to community setting because hospital environment itself is stressful. Yet, no study was done in Eastern Ethiopia, where substance use like Khat is very rampant. Objective. To assess depression and associated factors among adult inpatients at public hospitals of Harari Regional State, Eastern Ethiopia, from February 01 to 28, 2017. Methodology. Hospital based cross-sectional study design was employed on 492 admitted adult patients in Harari region hospitals. Consecutive sampling method was used to include study population. The data were collected by interviewee and analyzed by SPSS version 20.0. Bivariate and multivariate logistic regression analyses were employed. p value of 0.05 or less was considered to be statistically significant. Result. A total of 489 patients were interviewed with response rate of 99.4%. Having duration of 1-2 weeks in the hospital [AOR = 2.02, 95% CI: (1.28, 3.19], being diagnosed with chronic morbidity [AOR = 4.06, 95% CI: (2.23, 7.40], being users of psychoactive drugs [AOR = 2.24, 95% CI: (1.18, 4.24], and having been admitted to surgical ward [AOR = 0.50, 95% CI: (0.31, 0.81] were significantly associated with depression. Conclusion and Recommendation. Prevalence of depression among admitted inpatients was high. Therefore, increasing the awareness of benefits of early diagnosis of patients to prevent major form of depression and strengthening the clinical set-up and establishing good referral linkage with mental health institutions was considered to be cost-effective method to reduce its prevalence.

    The present study estimated the cost of advanced non-small cell lung cancer care for a cohort of 251 patients enrolled in a Brazilian public hospital and identified factors associated with the cost of treating the disease, considering sociodemographic, clinical and behavioral characteristics of patients, service utilization patterns and survival time. Estimates were obtained from the survey of direct medical cost per patient from the hospital's perspective. Data was collected from medical records and available hospital information systems. The ordinary least squares (OLS) method with logarithmic transformation of the dependent variable for the analysis of cost predictors was used to take into account the positive skewness of the costs distribution. The average cost of NSCLC was US$ 5647 for patients, with 71% of costs being associated to outpatient care. The main components of cost were daily hospital bed stay (22.6%), radiotherapy (15.5%) and chemotherapy (38.5%). The OLS model reported that, with 5% significance level, patients with higher levels of education, with better physical performance and less advanced disease have higher treatment costs. After controlling for the patient's survival time, only education and service utilization patterns were statistically significant. Individuals who were hospitalized or made use of radiotherapy or chemotherapy had higher costs. The use of these outpatient and hospital services explained most of the treatment cost variation, with a significant increase of the adjusted R 2 of 0.111 to 0.449 after incorporation of these variables in the model. The explanatory power of the complete model reached 62%. Inequities in disease treatment costs were observed, pointing to the need for strategies that reduce lower socioeconomic status and population's hurdles to accessing cancer care services.

    Given the importance of developing healthy eating patterns during early childhood, policies to improve the elementary school food and beverage environments are critical. To examine the association between district and state policy and/or law requirements regarding competitive food and beverages and public elementary school availability of foods and beverages high in fats, sugars, and/or sodium. Multivariate, pooled, cross-sectional analysis of data gathered annually during elementary school years 2008-2009 through 2010-2011 in the United States. Survey respondents at 1814 elementary schools (1485 unique) in 957 districts in 45 states (food analysis) and 1830 elementary schools (1497 unique) in 962 districts and 45 states (beverage analysis). EXPOSURES Competitive food and beverage policy restrictions at the state and/or district levels. Competitive food and beverage availability. RESULTS Sweets were 11.2 percentage points less likely to be available (32.3% vs 43.5%) when both the district and state limited sugar content, respectively. Regular-fat baked goods were less available when the state law, alone and in combination with district policy, limited fat content. Regular-fat ice cream was less available when any policy (district, state law, or both) limited competitive food fat content. Sugar-sweetened beverages were 9.5 percentage points less likely to be available when prohibited by district policy (3.6% vs 13.1%). Higher-fat milks (2% or whole milk) were less available when prohibited by district policy or state law, with either jurisdiction's policy or law associated with an approximately 15 percentage point reduction in availability. Both district and state policies and/or laws have the potential to reduce in-school availability of high-sugar, high-fat foods and beverages. Given the need to reduce empty calories in children's diets, governmental policies at all levels may be an effective tool.

    We examined associations of several health outcomes with green and conventional low-income housing, where the prevalence of morbidities and environmental pollutants is elevated. We used questionnaires and a visual inspection to compare sick building syndrome (SBS) symptoms and asthma-related morbidity among residents in multifamily units in Boston, Massachusetts, between March 2012 and May 2013. Follow-up was approximately 1 year later. Adults living in green units reported 1.35 (95% confidence interval [CI] = 0.66, 2.05) fewer SBS symptoms than those living in conventional (control) homes (P green homes experienced substantially lower risk of asthma symptoms (odds ratio [OR] = 0.34; 95% CI = 0.12, 1.00), asthma attacks (OR = 0.31; 95% CI = 0.11, 0.88), hospital visits (OR = 0.24; 95% CI = 0.06, 0.88), and asthma-related school absences (OR = 0.21; 95% CI = 0.06, 0.74) than children living in conventional public housing. Participants living in green homes had improved health outcomes, which remained consistent over the study period. Green housing may provide a significant value in resource-poor settings where green construction or renovation could simultaneously reduce harmful indoor exposures, promote resident health, and reduce operational costs.

    Vaccine purchase cost has grown substantially over the last few decades. A closer look at vaccine prices reveals that not all vaccines shared the same increasing pattern. Various factors, such as vaccine attributes, competition, and supply shortages, could relate to price changes. In this study, we examined whether a variety of factors influenced the prices of noninfluenza childhood vaccines purchased in the public sector from 1996 to 2014. The association differed among price-capped vaccines and combination vaccines. There was an increasing time trend in real prices for non-price-capped vaccines, which was mostly offset by the effect of market longevity. The effect of competition in lowering prices was more pronounced among non-price-capped vaccines when manufacturer and vaccine component fixed effects were excluded. Supply shortage, manufacturer name change, and number of vaccine doses in series showed no effect. The results may help policy makers better understand price behaviors and make more informed decisions in vaccine planning and financing. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available The mitochondrial cascade hypothesis of dementia assumes mitochondrial dysfunction leading to reduced energy supply, impaired neuroplasticity, and finally cell death as one major pathomechanism underlying the continuum from brain aging over mild cognitive impairment to initial and advanced late onset Alzheimer’s disease. Accordingly, improving mitochondrial function has become an important strategy to treat the early stages of this continuum. The metabolic enhancer piracetam has been proposed as possible prototype for those compounds by increasing impaired mitochondrial function and related aspects like mechanisms of neuroplasticity. We here report that piracetam at therapeutically relevant concentrations improves neuritogenesis in the human cell line SH-SY5Y over conditions mirroring the whole spectrum of age-associated cognitive decline. These effects go parallel with improvement of impaired mitochondrial dynamics shifting back fission and fusion balance to the energetically more favorable fusion site. Impaired fission and fusion balance can also be induced by a reduction of the mitochondrial permeability transition pore (mPTP function as atractyloside which indicates the mPTP has similar effects on mitochondrial dynamics. These changes are also reduced by piracetam. These findings suggest the mPTP as an important target for the beneficial effects of piracetam on mitochondrial function.

    Full Text Available This paper develops a reflexive approach on the relations between research and action in works on participatory democracy; a topic in which bridges are numerous between academic, political and activist fields. It aims at analyzing the impact of the close links between sociologists and actors on the methods and results of research and, reciprocally, the role of sociology in developing participatory practices. Relying on Michael Burawoy’s reflection on “public sociology”, our own research experience in an association, and other research studies conducted in Europe, we define five ways sociologists carry out research on participatory democracy in collaboration with the actors. Beyond a reflection on the social reception of our research, the challenge is to develop a critical and committed sociology on participatory democracy with a view to contributing to the political debate and public action from a critical viewpoint.

    Water deficit is a key factor to induce flowering in many woody plants, but reports on the molecular mechanisms of floral induction and flowering by water deficit are scarce. Here, we analyzed the morphology, cytology, and different hormone levels of lemon buds during floral inductive water deficits. Higher levels of ABA were observed, and the initiation of floral bud differentiation was examined by paraffin sections analysis. A total of 1638 differentially expressed genes (DEGs) were identified by RNA sequencing. DEGs were related to flowering, hormone biosynthesis, or metabolism. The expression of some DEGs was associated with floral induction by real-time PCR analysis. However, some DEGs may not have anything to do with flowering induction/flower development; they may be involved in general stress/drought response. Four genes from the phosphatidylethanolamine-binding protein family were further investigated. Ectopic expression of these genes in Arabidopsis changed the flowering time of transgenic plants. Furthermore, the 5' flanking region of these genes was also isolated and sequence analysis revealed the presence of several putative cis -regulatory elements, including basic elements and hormone regulation elements. The spatial and temporal expression patterns of these promoters were investigated under water deficit treatment. Based on these findings, we propose a model for citrus flowering under water deficit conditions, which will enable us to further understand the molecular mechanism of water deficit-regulated flowering in citrus. Based on gene activity during floral inductive water deficits identified by RNA sequencing and genes associated with lemon floral transition, a model for citrus flowering under water deficit conditions is proposed.

    Full Text Available Smart card data provide valuable insights and massive samples for enhancing the understanding of transfer behavior between metro and public bicycle. However, smart cards for metro and public bicycle are often issued and managed by independent companies and this results in the same commuter having different identity tags in the metro and public bicycle smart card systems. The primary objective of this study is to develop a data fusion methodology for matching metro and public bicycle smart cards for the same commuter using historical smart card data. A novel method with association rules to match the data derived from the two systems is proposed and validation was performed. The results showed that our proposed method successfully matched 573 pairs of smart cards with an accuracy of 100%. We also validated the association rules method through visualization of individual metro and public bicycle trips. Based on the matched cards, interesting findings of metro-bicycle transfer have been derived, including the spatial pattern of the public bicycle as first/last mile solution as well as the duration of a metro trip chain.

    In an age of political turmoil and mistrust of governments, having an outlet for creative problem solving that involves all aspects of communities during disasters is critical. Additionally, there is a need for outlets that save taxpayer money for particular projects, such as road construction or infrastructure protection. Public-private partnerships are one way to accomplish these goals. Utilised correctly, a public-private partnership is a win-win situation for all participants. This paper will make the case for the continued support from all sectors for public-private partnerships. A description of public-private partnerships will be given to show the broad spectrum of opportunities for such a partnership. In addition, a case study of a public-private partnership called SAFER Santa Rosa is explored as the programme is oriented towards disasters, but keeps the community engaged all year round. Finally, an example is presented of an initiative that not only exemplifies the spirit of public-private partnerships, but has attracted international recognition because it is simple, replicable, cost-effective and valuable to both the private sector and the public sector. The Business Emergency Response Toolkit bag is a true public-private success story. It is hoped that the reader will be able to replicate the ideas discussed herein in their own community.

    Human resources are vital for delivering health services, and health systems cannot function effectively without sufficient numbers of skilled, motivated, and well-supported health workers. Job satisfaction of health workers is important for motivation and efficiency, as higher job satisfaction improves both employee performance and patient satisfaction. Even though several studies have addressed job satisfaction among healthcare professionals in different part of the world, there are relatively few studies on healthcare professionals' job satisfaction in Ethiopia. A facility-based cross-sectional study was conducted among health professionals working in health centers in April 2015 using self-administered structured questionnaires. All 322 health professionals working in 23 randomly selected public health centers were included. Factor scores were computed for the identified items by varimax rotation to represent satisfaction. Multivariate linear regression analysis was performed, and the effect of independent variables on the regression factor score quantified. Three hundred eight respondents participated with a response rate of 95.56%. The overall level of job satisfaction was 41.46%. Compensation (benefits) (beta 0.448 [95% CI 0.341 to 0.554]), recognition by management (beta 0.132 [95% CI 0.035 to 0.228]), and opportunity for development (beta 0.123 [95% CI 0.020 to 0.226]) were associated with job satisfaction. A unit increase in salary and incentives and recognition by management scores resulted in 0.459 (95% CI 0.356 to 0.561) and 0.156 (95% CI 0.065 to 0.247) unit increases in job satisfaction scores, respectively. The overall level of job satisfaction in health professionals was low. Salary and incentives, recognition by management, developmental opportunities, and patient appreciation were strong predictors of job satisfaction.

    A community-based intervention, the Crown Health Project (CHP), was developed by the Ministry of Health. It was implemented on a small-scale in Al-Jouf Region in Northern Kingdom of Saudi Arabia to assess its feasibility and effectiveness so that it can be scaled up. This study primarily aimed at investigating factors associated with the awareness of CHP in order to improve subsequent campaigns for the program in Al-Jouf and other regions. A secondary aim was to assess possible changes of public awareness during intensification of the awareness campaign between October 2011 and May 2012. A pre- and post-questionnaire cross-sectional approach was undertaken, and the intervention was an awareness campaign. Variables collected included demographic characteristics (e.g., age, gender, education, occupation, urban/rural residence) and CHP awareness (its existence, sources of knowledge about CHP, its goals and objectives, its target diseases, location of activities, participation in such activities). Logistic regression was used to analyze the awareness of the program according to participant characteristics, with a time of the survey as a variable. Awareness of the program was found to be 11 times higher among postsurvey respondents than presurvey respondents. Respondents of the second survey were better at correctly identifying "health education" as the main goal of the CHP (odds ratio [OR], 4.1; 95% confidence interval [CI], 3.1-5.5), "noncommunicable diseases" as the main diseases targeted (OR, 4.8; 95% CI, 3.6-6.4) and "attention to health" as the purpose (OR, 6.0; 95% CI, 4.0-8.9). The different activities of the CHP were successful in dramatically increasing awareness of the CHP program in Al-Jouf.

Methods: A pre- and post-questionnaire cross-sectional approach was undertaken, and the intervention was an awareness campaign. Variables collected included demographic characteristics (e.g., age, gender, education, occupation, urban/rural residence and CHP awareness (its existence, sources of knowledge about CHP, its goals and objectives, its target diseases, location of activities, participation in such activities. Logistic regression was used to analyze the awareness of the program according to participant characteristics, with a time of the survey as a variable. Results: Awareness of the program was found to be 11 times higher among postsurvey respondents than presurvey respondents. Respondents of the second survey were better at correctly identifying "health education" as the main goal of the CHP (odds ratio [OR], 4.1; 95% confidence interval [CI], 3.1-5.5, "noncommunicable diseases" as the main diseases targeted (OR, 4.8; 95% CI, 3.6-6.4 and "attention to health" as the purpose (OR, 6.0; 95% CI, 4.0-8.9. Conclusion: The different activities of the CHP were successful in dramatically increasing awareness of the CHP program in Al-Jouf.

    Multiferroic behavior in perovskite-related metal-organic frameworks of general formula [(CH(3))(2)NH(2)]M(HCOO)(3), where M = Mn, Fe, Co, and Ni, is reported. All four compounds exhibit paraelectric-antiferroelectric phase transition behavior in the temperature range 160-185 K (Mn: 185 K, Fe: 160 K; Co: 165 K; Ni: 180 K); this is associated with an order-disorder transition involving the hydrogen bonded dimethylammonium cations. On further cooling, the compounds become canted weak ferromagnets below 40 K. This research opens up a new class of multiferroics in which the electrical ordering is achieved by means of hydrogen bonding.

  1. Expression microarray meta-analysis identifies genes associated with Ras/MAPK and related pathways in progression of muscle-invasive bladder transition cell carcinoma.

    Full Text Available The effective detection and management of muscle-invasive bladder Transition Cell Carcinoma (TCC continues to be an urgent clinical challenge. While some differences of gene expression and function in papillary (Ta, superficial (T1 and muscle-invasive (≥T2 bladder cancers have been investigated, the understanding of mechanisms involved in the progression of bladder tumors remains incomplete. Statistical methods of pathway-enrichment, cluster analysis and text-mining can extract and help interpret functional information about gene expression patterns in large sets of genomic data. The public availability of patient-derived expression microarray data allows open access and analysis of large amounts of clinical data. Using these resources, we investigated gene expression differences associated with tumor progression and muscle-invasive TCC. Gene expression was calculated relative to Ta tumors to assess progression-associated differences, revealing a network of genes related to Ras/MAPK and PI3K signaling pathways with increased expression. Further, we identified genes within this network that are similarly expressed in superficial Ta and T1 stages but altered in muscle-invasive T2 tumors, finding 7 genes (COL3A1, COL5A1, COL11A1, FN1, ErbB3, MAPK10 and CDC25C whose expression patterns in muscle-invasive tumors are consistent in 5 to 7 independent outside microarray studies. Further, we found increased expression of the fibrillar collagen proteins COL3A1 and COL5A1 in muscle-invasive tumor samples and metastatic T24 cells. Our results suggest that increased expression of genes involved in mitogenic signaling may support the progression of muscle-invasive bladder tumors that generally lack activating mutations in these pathways, while expression changes of fibrillar collagens, fibronectin and specific signaling proteins are associated with muscle-invasive disease. These results identify potential biomarkers and targets for TCC treatments, and

    Full Text Available Overnight operations pose a challenge because our circadian biology promotes sleepiness and dissipates wakefulness at night. Since the circadian effect on cognitive functions magnifies with increasing sleep pressure, cognitive deficits associated with night work are likely to be most acute with extended wakefulness, such as during the transition from a day shift to night shift.To test this hypothesis we measured selective attention (with visual search, vigilance (with Psychomotor Vigilance Task [PVT] and alertness (with a visual analog scale in a shift work simulation protocol, which included four day shifts followed by three night shifts. There was a nocturnal decline in cognitive processes, some of which were most pronounced on the first night shift. The nighttime decrease in visual search sensitivity was most pronounced on the first night compared with subsequent nights (p = .04, and this was accompanied by a trend towards selective attention becoming 'fast and sloppy'. The nighttime increase in attentional lapses on the PVT was significantly greater on the first night compared to subsequent nights (p<.05 indicating an impaired ability to sustain focus. The nighttime decrease in subjective alertness was also greatest on the first night compared with subsequent nights (p<.05.These nocturnal deficits in attention and alertness offer some insight into why occupational errors, accidents, and injuries are pronounced during night work compared to day work. Examination of the nighttime vulnerabilities underlying the deployment of attention can be informative for the design of optimal work schedules and the implementation of effective countermeasures for performance deficits during night work.

    Full Text Available European integration is not just a goal of the foreign policy of the Republic of Moldova, but also a natural aspiration of an European nation to join the European family and the signing of the Association Agreement between Moldova and the European Union is an important step in achieving this goal. The Republic of Moldova has developed and continues to promote rigorous reforms in the area of public finance management. In this article we have analyzed the main reforms and achievements in the field of public finance management in the Republic of Moldova, their importance by reference to good European practices, but also the need to continue them in the context of signing the Association Agreement. The authors argue that until now, the public finance management reform had been focused mainly on the planning and execution phases of National Public Budget, nonetheless the main problems lay in poor budgetary reporting and control. Corruption and fraud are the main risk areas for all the promoted reforms. The conclusion of this paper is that the most urgent actions that should be undertaken consist in improving public procurement procedures, enhancing the internal control, financial inspection and external audit. Only in such a way trustful relation with EU could be created and this is particularly important as it could permit to absorb more European funds to invest in the economic and social development in our country.

    Capturing stormwater is becoming a new standard for sustainable urban stormwater management, which can be used to supplement water supply portfolios in water-stressed cities. The key advantage of harvesting stormwater is to use low impact development (LID) systems for treatment to meet water quality requirement for non-potable uses. However, the lack of scientific studies to validate the safety of such practice has limited its adoption. Microbial hazards in stormwater, especially human viruses, represent the primary public health threat. Using adenovirus and norovirus as target pathogens, we investigated the viral health risk associated with a generic scenario of urban stormwater harvesting practice and its application for three non-potable uses: 1) toilet flushing, 2) showering, and 3) food-crop irrigation. The Quantitative Microbial Risk Assessment (QMRA) results showed that food-crop irrigation has the highest annual viral infection risk (median range: 6.8 × 10 −4 –9.7 × 10 −1 per-person-per-year or pppy), followed by showering (3.6 × 10 −7 –4.3 × 10 −2 pppy), and toilet flushing (1.1 × 10 −7 –1.3 × 10 −4 pppy). Disease burden of each stormwater use was ranked in the same order as its viral infection risk: food-crop irrigation > showering > toilet flushing. The median and 95th percentile risk values of toilet-flushing using treated stormwater are below U.S. EPA annual risk benchmark of ≤ 10 −4 pppy, whereas the disease burdens of both toilet-flushing and showering are within the WHO recommended disease burdens of ≤ 10 −6 DALYs pppy. However, the acceptability of showering risk interpreted based on the U.S. EPA and WHO benchmarks is in disagreement. These results confirm the safety of stormwater application in toilet flushing, but call for further research to fill the data gaps in risk modeling as well as risk benchmarks. - Highlights: • Human health risks for three non-potable uses of treated stormwater are modeled. • Crop

    To analyze the publication rate of poster and podium presentations at Arthroscopy Association of North America (AANA) annual meetings from 2008 to 2012. An online search using PubMed and Google Scholar for all published manuscripts associated with abstracts presented from 2008 to 2012 AANA annual meetings was performed. Abstracts were classified by presentation type (poster vs podium), and the journal and publication date were recorded for all published abstracts. Descriptive statistics, logistic regression, and Fisher's exact tests were performed, with P presentation (65% overall acceptance rate). There were 328 podium (22% acceptance rate) and 648 poster (43% acceptance rate) presentations. Of the 976 accepted abstracts, 479 (49%) were published within 3 years in peer-reviewed journals. The overall publication rates for podium and poster presentations were 59% (n = 193) and 44% (n = 286), respectively. Podium presentations were significantly more likely to be published within 3 years compared with poster presentations (P poster presentations (1.3 ± 1.2 vs 1.1 ± 1.3 years, P = .0633). Over the 5-year study period, the overall abstract acceptance rate (P poster presentation (P presentation (P = .5638). The most common journals of publication were Arthroscopy (n = 157, 32.7%) followed by American Journal of Sports Medicine (n = 93, 19.4%). The overall publication rate of abstracts presented at AANA annual meetings is 49%, with podium presentations 1.8 times more likely to be published than poster presentations. The overall abstract acceptance rate and the rate of abstracts accepted for poster presentation increased significantly over time, whereas there was no significant increase in the rate of abstracts accepted for podium presentation. The publication rates of abstracts presented at the AANA annual meetings demonstrate the meetings' impact and importance to the advancement of the scientific literature.

    Currently, the diagnosis of esophageal motility disorders is in part based upon a hierarchical algorithm in which abnormalities of the esophagogastric junction (EGJ) is prioritized. An important metric in evaluating the EGJ is the integrated relaxation pressure (IRP). Patients who do not have achalasia but are found to have an elevated IRP are diagnosed with EGJ outflow obstruction. It has been our observation that a subset of these patients also has a second named motility disorder and may also have abnormal bolus transit. The aim of this study is to determine the frequency of abnormal body motility and or abnormal bolus movement in patients with EGJ outflow obstruction. Further, in an effort to evaluate the potential clinical value in measuring bolus transit as a complement to esophageal manometry, specifically in patients with EGJ outflow obstruction, we analyzed the presenting symptoms of these patients. A total of 807 patients with a mean age of 53 years completed esophageal function testing with impedance monitoring and high-resolution manometry between January 2012 and October 2016. There were 74 patients with achalasia who were excluded from the study. Of the remaining 733 patients, 138 (19%) had an elevated IRP and were given a diagnosis of EGJ outflow obstruction. Among these patients, 56 (40%) were diagnosed with an abnormal motility pattern to liquids (ineffective esophageal motility = 28, distal esophageal spasm = 19, Jackhammer = 6), of which 44 (76%) had abnormal bolus transit to liquids, viscous, or both. In contrast, there were 82 patients with EGJ outflow obstruction and normal esophageal motility, of which 33 (40%) had abnormal bolus transit. Patients with preserved esophageal motility and EGJ outflow obstruction were then evaluated. Of the 733 patients, 299 (40%) had intact esophageal motility. Of the 299 patients with normal esophageal motility, 56 patients had an elevated IRP, of which 16 (28%) had abnormal bolus transit. There were 243 (33

    Full Text Available It is known that an ineffective antibiotic treatment can induce morphological shifts in uropathogenic Escherichia coli (UPEC but the virulence properties during these shifts remain to be studied. The present study examines changes in global gene expression patterns and in virulence factor-associated genes in an extended spectrum beta-lactamase (ESBL-producing UPEC (ESBL019 during the morphologic transitions induced by an ineffective antibiotic and in the presence of human primary bladder epithelial cells. Microarray results showed that the different morphological states of ESBL019 had significant transcriptional alterations of a large number of genes (Transition; 7%, Filamentation; 32%, and Reverted 19% of the entities on the array. All three morphological states of ESBL019 were associated with a decreased energy metabolism, altered iron acquisition systems and altered adhesion expression. In addition, genes associated with LPS synthesis and bacterial motility was also altered in all the morphological states. Furthermore, the transition state induced a significantly higher release of TNF-α from bladder epithelial cells compared to all other morphologies, while the reverted state was unable to induce TNF-α release. Our findings show that the morphological shifts induced by ineffective antibiotics are associated with significant transcriptional virulence alterations in ESBL-producing UPEC, which may affect survival and persistence in the urinary tract.

    Insulin therapy is lifesaving treatment for individuals with type 1 diabetes (T1D). Its initiation maybe associated with significant weight gain because of change from a catabolic to an anabolic state. Excessive weight-gain increases the risk of obesity and is associated with chronic disease. To examine if change in body mass index (BMI) among children in the 6 months after diagnosis with type 1 diabetes mellitus is associated with long-term obesity. This was a population-based retrospective study of 377 children (aged 2-18 yr) with type 1 diabetes. Measured heights and weights were used to calculate BMI z-scores based on Centers for Disease Control and Prevention (CDC) cut-points. Generalized Linear Models using BMI group, and age group at diagnosis; postdiagnosis weight change; and sex were applied to assess associations between postdiagnosis weight change and BMI z-score at transition to adult care. Mean BMI z-score increased from 0.28 at diagnosis, to 0.53 at 6 months and 0.66 at transition to adult care. Change in BMI z-scores differed by initial BMI group and magnitude of postdiagnosis weight change. Younger children (11 yr) had higher (p = 0.004) BMI z-scores at diagnosis but not at last visit (p = 0.1) than older (≥11 yr) children at diagnosis. BMI z-score at diagnosis, postdiagnosis weight change, female sex, and longer duration with TID were associated with higher BMI z-score at time of transition. BMI z-score at diagnosis was the strongest predictor of BMI z-score at time of transition to adult care, however; its effect was mediated by magnitude of weight change 6 months after diagnosis, sex, and age group at diagnosis. © 2016 John Wiley & Sons A/S.

    2015-08-01

    Previous research has shown that public transit use may be associated with active transportation. Access to a car may influence active transportation of transit riders. Using the 2009 United States National Household Travel Survey (NHTS), transit users ≥ 16 years old (n = 25,550) were categorized according to driver status and number of cars and drivers in the household. This typology ranged from choice transit riders (ie, "fully motorized drivers") to transit-dependent riders (ie, "unmotorized nondriver"). Transit trips, walking trips, and bicycling trips of transit users are estimated in negative binomial models against the car availability typology. Sixteen percent of participants took transit in the past month; most (86%) lived in car-owning households. As income increased, car availability also increased. Transit user groups with lower car availability were generally more likely than fully motorized drivers to take more public transit, walking, and bicycle trips. Transit riders have varying levels of vehicle access; their use of combinations of alternative modes of transportation fluctuates accordingly. Transit-dependent individuals without cars or sharing cars used active transportation more frequently than car owners. Policies to reduce vehicle ownership in households may enable increases in the use of alternative modes of transportation for transit users, even when cars are still owned.

    Understanding who takes advantage of new transit (public transportation) interventions is important for personal and environmental health. We examine transit ridership for residents living near a new light rail construction as part of “complete street,” pedestrian-friendly improvements. Adult residents (n=536) completed surveys and wore accelerometer and GPS units that tracked ridership before and after new transit service started. Transit riders were more physically active. Those from environments rated as more walkable were likely to be continuing transit riders. Place attachment, but not perceived physical incivilities on the path to transit, was associated with those who continued to ride or became new riders of transit. This effect was mediated through pro-city attitudes, which emphasize how the new service makes residents eager to explore areas around transit. Thus, place attachment, along with physical and health conditions, may be important predictors and promoters of transit use. PMID:27672237

    Full Text Available Human astroviruses have been increasingly identified as important agents of diarrheal disease in children. However, the disease burden of astrovirus infection is still incompletely assessed. This paper reports results on the epidemiological and clinical characteristics of astrovirus-associated diarrhea, as well as the impact of astrovirus infection on the ambulatory setting at a Public Hospital in Córdoba city, Argentina. From February 2001 through January 2002, 97 randomly selected outpatient visits for diarrhea among children 0.05. According to our estimation about one out of seventy-four children in this cohort would be assisted annually for an astroviral-diarrheal episode in the Public Hospital and one out of eight diarrheal cases could be attributed to astrovirus infection. Astrovirus is a common symptomatic infection in pediatric outpatient visits in the public hospital in the study area, contributing 12.37% of the overall morbidity from diarrhea.

    Genome-wide association studies and biobanks are at the forefront of genomics research and possess unprecedented potential to improve public health. However, for public health genomics to ultimately fulfill its potential, technological and scientific advances alone are insufficient. Scientists, ethicists, policy makers, and regulators must work closely together with research participants and communities in order to craft an equitable and just ethical framework, and a sustainable environment for effective policies. Such a framework should be a 'hybrid' form which balances equity and solidarity with entrepreneurship and scientific advances. A good balance between research and policy on one hand, and privacy, protection and trust on the other is the key for public health improvement based on advances in genomics science.

    Full Text Available A rat model of pulpitis/periapical periodontitis was used to study mechanisms underlying extraterritorial enhancement of masseter response associated with tooth inflammation. Periapical bone loss gradually increased and peaked at 6 weeks after complete Freund's adjuvant (CFA application to the upper molar tooth pulp (M1. On day 3, the number of Fos-immunoreactive (IR cells was significantly larger in M1 CFA rats compared with M1 vehicle (veh rats in the trigeminal subnucleus interpolaris/caudalis transition zone (Vi/Vc. The number of Fos-IR cells was significantly larger in M1 CFA and masseter (Mass capsaicin applied (M1 CFA/Mass cap rats compared with M1 veh/Mass veh rats in the contralateral Vc and Vi/Vc. The number of phosphorylated extracellular signal-regulated kinase (pERK-IR cells was significantly larger in M1 CFA/Mass cap and M1 veh/Mass cap rats compared to Mass-vehicle applied rats with M1 vehicle or CFA in the Vi/Vc. Pulpal CFA application caused significant increase in the number of Fos-IR cells in the Vi/Vc but not Vc on week 6. The number of pERK-IR cells was significantly lager in the rats with capsaicin application to the Mass compared to Mass-vehicle treated rats after pulpal CFA- or vehicle-application. However, capsaicin application to the Mass did not further affect the number of Fos-IR cells in the Vi/Vc in pulpal CFA-applied rats. The digastric electromyographic (d-EMG activity after Mass-capsaicin application was significantly increased on day 3 and lasted longer at 6 weeks after pulpal CFA application, and these increase and duration were significantly attenuated by i.t. PD98059, a MEK1 inhibitor. These findings suggest that Vi/Vc and Vc neuronal excitation is involved in the facilitation of extraterritorial hyperalgesia for Mass primed with periapical periodontitis or acute pulpal-inflammation. Furthermore, phosphorylation of ERK in the Vi/Vc and Vc play pivotal roles in masseter hyperalgesia after pulpitis or

    Little is known about how the views of the public are related to self-stigma among people with mental health problems. Despite increasing activity aimed at reducing mental illness stigma, there is little evidence to guide and inform specific anti-stigma campaign development and messages to be used in mass campaigns. A better understanding of the association between public knowledge, attitudes and behaviours and the internalization of stigma among people with mental health problems is needed. This study links two large, international datasets to explore the association between public stigma in 14 European countries (Eurobarometer survey) and individual reports of self-stigma, perceived discrimination and empowerment among persons with mental illness (n=1835) residing in those countries [the Global Alliance of Mental Illness Advocacy Networks (GAMIAN) study]. Individuals with mental illness living in countries with less stigmatizing attitudes, higher rates of help-seeking and treatment utilization and better perceived access to information had lower rates of self-stigma and perceived discrimination and those living in countries where the public felt more comfortable talking to people with mental illness had less self-stigma and felt more empowered. Targeting the general public through mass anti-stigma interventions may lead to a virtuous cycle by disrupting the negative feedback engendered by public stigma, thereby reducing self-stigma among people with mental health problems. A combined approach involving knowledge, attitudes and behaviour is needed; mass interventions that facilitate disclosure and positive social contact may be the most effective. Improving availability of information about mental health issues and facilitating access to care and help-seeking also show promise with regard to stigma.

  20. Public attitudes to climate change and carbon mitigation—Implications for energy-associated behaviours

    This work explores public opinions regarding climate change and mitigation options and examines how psychological factors, such as attitudes, norms, and willingness to pay, determine self-reported energy-efficient behaviour. The aim is to create knowledge for the design and implementation of policy measures. The results of an opinion poll conducted in 2005 and 2010 are compared. The number of respondents favouring new technologies as a way to reduce emissions was substantially lower in 2010 than in 2005, whereas there was an increase in the number of people who acknowledged that lifestyle changes are necessary to counteract climate changes. This indicates an increased awareness among the public of the need for lifestyle changes, which could facilitate implementation of policies promoting environmental behaviour. Renewable energy and energy saving measures were ranked as the top two measures for mitigating climate change in both polls. In determining which energy behaviours of the public are determined by psychological factors, an analysis of the 2010 survey revealed that respondents with pro-environmental attitudes towards global warming favour significantly increased use of renewable energy technologies and greater engagement in energy-efficient behaviours. - Highlights: ► Public opinion place priority to environmental issues and beliefs to change current lifestyle. ► A decline in favoring new technologies as a way to reduce emissions in 2010 compare to 2005 poll. ► Environmental attitudes relate to favor of renewable energy technologies. ► Environmental attitudes relate to households energy efficient behaviour

  2. Contracts on electric power supply set up between communities (communal associations, countries) and public electricity utilities

    1976-01-01

    There is not any original communal right to energy supply for the population. The affiliation of local power supply to the local administration cannot be justified either by the public purpose of service or by the term provision of existence. The utilities do not get a communal license when getting the so-called licensing contract. According to its legal nature, the licensing contract is a mixture of legal positions composed of elements of the civil law and the public law. (Administrative lawsuit). The so-called power supply contract is a mutual legal relationship under civil law on the utilization of electric power, made to last. (Permanent obligation for utilization). When concluding both contracts, it is a matter of economic activities undertaken by the communities. Fiscal considerations are in the foreground. Legal regulations concerning roads and distances and serving as starting points for concluding a licensing contract are alien to the system and are to be abolished. Communities should only be responsible for local energy supply on a basis under public law. In lieu of it a stronger obligation to be met by large utilities ought to be ensured by ties under public law.

    Transits of Venus and Mercury have inspired artistic creation of all kinds. After having been the first to witness a Venusian transit, in 1639, Jeremiah Horrocks expressed his feelings in poetry. Production has subsequently widened to include songs, short stories, novels, novellas, sermons, theatre, film, engravings, paintings, photography, medals, sculpture, stained glass, cartoons, stamps, music, opera, flower arrangements, and food and drink. Transit creations are reviewed, with emphasis on the English- and French-speaking worlds. It is found that transits of Mercury inspire much less creation than those of Venus, despite being much more frequent, and arguably of no less astronomical significance. It is suggested that this is primarily due to the mythological associations of Venus with sex and love, which are more powerful and gripping than Mercury's mythological role as a messenger and protector of traders and thieves. The lesson for those presenting the night sky to the public is that sex sells.

  5. Effect of the expansion associated with the plutonium α-β-γ phase transitions on storage can integrity

    2001-11-01

    The effects of the volume expansion of plutonium metal through the α-β and β-γ phase transitions on a stainless steel storage container were examined. A cylindrical plutonium ingot was placed in the axial center of an annealed stainless steel cylinder and thermally cycled until a steady state in the strain response of the cylinder was reached. The average plastic hoop strain was 1.47% and 1.55% after six and four cycles through the α-β and α-β-γ phase transitions, respectively. Elastic strain was ˜0.2%, indicating a 8.96 MPa back pressure on the Pu ingot. This is an order of magnitude less than the compressive yield strength of α- and β-Pu at the transition temperature. Metallographic analyses indicate that anisotropic expansion of the Pu ingot is due to preferentially oriented grain growth of the β-Pu along the axial direction due to stress applied by the steel cylinder during the α-β phase transition.

    Full Text Available Local preparedness against earthquakes has been recently highlighted in research and policies on disaster management and risk reduction promotion in Iran. To advance the understanding of public preparedness and how it can be applied in diverse localities, further information is required about the predictors of people’s adoption of mitigation activities and earthquake preparedness. A synthesis of the available published research results on earthquake preparedness and the influencing factors in Iran are presented in this literature review. It emphasizes the complexity of both the concept of preparedness and the contextual factors that mediate its adoption. The predominant roles of public awareness, trusted information resources, social capital and community collaboration as predictors are discussed. 

  8. Analysis of nuclear accidents and associated problems relevant to public perception of risk

    The analytical study of nuclear accidents, even if they are limited in number, forms a significant part of the vast discipline of industrial plant risk analysis. The retrospective analysis of the causes and various elements which contributed to the evolution of real accidents, as well as, the evaluation of the consequences and lessons learned, constitute a bank of information which, when suitably elaborated through a process of rational synthesis, can strongly influence the preparation of safety normatives, plant design specifications, environmental impacts assessments, and the perception of risk. This latter aspect is gaining importance today as growing public awareness and sensitivity towards the development and use of new technologies now bear heavily on new plant decision making. This paper examines how the public perception of risk regarding nuclear energy has been influenced by the events surrounding the Chernobyl and Three Mile Island accidents and the way in which information dissemination concerning these accidents was handled by mass media

    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.

    At sexual medicine meetings throughout the world, hundreds of scientific abstracts are presented each year. To our knowledge, no previous studies have looked at the rate of publication of these studies in a peer-reviewed journal. To define the fate of abstracts presented at sexual medicine sessions at the annual meeting of the American Urological Association (AUA) and to describe the factors predicting ultimate publication in scientific journals. All abstracts presented at the 2006 and 2007 AUA annual meeting were surveyed to find sexual medicine abstracts. Publication status as of October 2009 was assessed using the Medline database. Abstract parameters were recorded including number of authors, country of origin, clinical or basic research, and area of sexual research. Predictors of publication were analyzed using a multivariable model. Publication status of all sexual medicine abstracts presented at the 2006 and 2007 AUA annual meetings. A total of 208 sexual medicine abstracts were presented in 2006 and 2007. Fifty-one percent of these were published by October 2009. On univariate analysis, the predictors of publication in a peer-reviewed journal included the number of authors (r=0.22, Pacademic centers (RR 2.7, CI 1.7-4.3, Pacademic center (OR 5.9, CI 2.8-12.7, Pmedicine abstracts presented at the 2006 and 2007 annual AUA meetings have been published within 2 to 3 years of the date of presentation. Studies originating from academic centers were six times more likely to be published in a peer-reviewed journal. © 2013 International Society for Sexual Medicine.

    In October and November 2014, the New Jersey Department of Health received reports of 3 patients who developed Enterococcus faecalis endocarditis after undergoing surgical procedures at the same oral surgery practice in New Jersey. Bacterial endocarditis is an uncommon but life-threatening condition; 3 patients with enterococcal endocarditis associated with a single oral surgery practice is unusual. An investigation was initiated because of the potential ongoing public health risk. Public health officials conducted retrospective surveillance to identify additional patients with endocarditis associated with the practice. They interviewed patients using a standardized questionnaire. An investigative public health team inspected the office environment, interviewed staff, and reviewed medical records. Public health officials identified 15 confirmed patients with enterococcal endocarditis of those patients who underwent procedures from December 2012 through August 2014. Among these patients, 12 (80%) underwent cardiac surgery. One (7%) patient died from complications of endocarditis and subsequent cardiac surgery. Breaches of recommended infection prevention practices were identified that might have resulted in transmission of enterococci during the administration of intravenous sedation, including failure to perform hand hygiene and failure to maintain aseptic technique when performing procedures and handling medications. This investigation highlights the importance of adhering to infection prevention recommendations in dental care settings. No additional patients with endocarditis were identified after infection prevention and control recommendations were implemented. Infection prevention training should be emphasized at all levels of professional dental training. All dental health care personnel establishing intravenous treatment and administering intravenous medications should be trained in safe injection practices.

    The reanalysis of existing GWAS data represents a powerful and cost-effective opportunity to gain insights into the genetics of complex diseases. By reanalyzing publicly available type 2 diabetes (T2D) genome-wide association studies (GWAS) data for 70,127 subjects, we identify seven novel associated regions, five driven by common variants (LYPLAL1, NEUROG3, CAMKK2, ABO, and GIP genes), one by a low-frequency (EHMT2), and one driven by a rare variant in chromosome Xq23, rs146662057, associated with a twofold increased risk for T2D in males. rs146662057 is located within an active enhancer associated with the expression of Angiotensin II Receptor type 2 gene (AGTR2), a modulator of insulin sensitivity, and exhibits allelic specific activity in muscle cells. Beyond providing insights into the genetics and pathophysiology of T2D, these results also underscore the value of reanalyzing publicly available data using novel genetic resources and analytical approaches.

    Worse health outcomes among those living in poverty are due in part to lower rates of health insurance and barriers to care. As the Affordable Care Act reduced financial barriers, identifying persistent barriers to accessible health care continues to be important. We examined whether the built environment as reflected by Walk Score™ (a measure of walkability to neighborhood resources) and Transit Score™ (a measure of transit access) is associated with having a usual source of care among low-income adults, newly enrolled in Medicaid. We received responses from 312 out of 1000 new Medicaid enrollees in Philadelphia, a large, densely populated urban area, who were surveyed between 2015 and 2016 to determine if they had identified a usual source of outpatient primary care. Respondents living at an address with a low Walk Scores (< 70) had 84% lower odds of having a usual source of care (OR 0.16, 95% CI 0.04-0.61). Transit scores were not associated with having a usual source of care. Walk Score may be a tool for policy makers and providers of care to identify populations at risk for worse primary care access.

    The yearly environmental conference will hold on September 2013 to evaluate the negotiations led at the national and local levels for december 2012. The government will have then to decide of an energy programming bill which will be submitted to the Parliament at the beginning of the year 2014. 30 main propositions have emerged of the decentralised debates. One of them is the ecological taxation which raise the question of the gas oil and petrol taxation. The current environmental taxes are for almost three quarters of them taxes on energy consumptions and mainly on fossil energies. The Economic, Social and Environmental Council, gives his opinion on the way to find resources to ensure the ecological and energy transition while reducing the public deficit of the State. (O.M.)

  19. Communicating Risks Associated with Onshore Oil and Gas Development: A Reflective Case Study from a Public Health Perspective

    Science.gov (United States)

    Blake, U.

    2017-12-01

    The growth of onshore oil and natural gas development (OGD) over the past decade has led to an increase in environmental health concerns caused by potential risks associated with industry activities. While the industry has shown commitment to protecting the environment and the health and safety of all who share it (through the development of standards and best practices, and the support of relevant research projects), the negative rhetoric persists. The persistence can be related to differences in the perception of risks, complicated by the uncertainties associated with published and unpublished scientific findings, which are experienced and communicated differently by scientists, regulators, industry and the public. For example, to industry operators, hydraulic fracturing is a "well completion" operation, during which fracturing fluid is pumped down a well to the target formation, under high pressure (pressure high enough to exceed the formation fracture gradient). However, to the general public, the term hydraulic fracturing represents the entire onshore exploration and production operation (from pad development to the production of the resource). This difference in language is the tip of the iceberg that represents the challenges industry faces when communicating its operations to the public. By reflecting on industry experiences, this presentation offers a reflective case study that relates the challenges of navigating and communicating within a narrative of purported health effects, to risk perception and communication theories.

    Work-related violence is one of the most serious threats to employee safety and health. To ascertain the extent of self-reported violence or threats of violence at work in relation to the general health of public sector employees. The study population comprised 9,611 female (83%) and male public employees in Sweden. A questionnaire based on items derived mainly from validated instruments was constructed to cover aspects such as health, lifestyle, and physical and psychosocial work conditions. One in three employees reported work-related violence, with the highest proportions among psychiatric nurses (79%) and psychiatric attendants (75%). Work-related violence more often affected those who were worked worked nights, or reported poor health. Regardless of gender, age, hours of work, night work, and type of occupation, exposure to work-related violence was associated with less than good general health, and this relationship was strongest for psychiatric nurses (OR=3.19; 95% CI=1.28-7.98), medical doctors/dentists (OR=2.46; 95% CI=1.35-4.49), compulsory school teachers (OR=2.14; 95% CI=1.33-3.45), and other nurses (OR=1.87; 95% CI=1.23-2.84). Work-related violence was frequently reported by employees in the most common public sector occupations, and it was associated with poor health in both genders.

    Full Text Available Background: The expected knowledge translation from discovery into practice occurs when presentations from major scientific meetings are published in peer-reviewed literature. The purpose of this study was to determine the extent of complete publication of peer-reviewed articles arising from presentations at the biennial meetings of the Pan-African Pediatric Surgical Association (PAPSA. Materials and Methods: All the abstracts accepted for presentation at the biennial meeting of PAPSA between 2006 and 2010 were identified from the conference abstract booklets and published abstracts in the African Journal of Paediatric Surgery. The presentations were searched for publication in Medline/PubMed, Google Scholar, and African Journal OnLine through October 2012, using key words from the abstract title and names of authors listed in the abstracts. Results: A total of 164 abstracts were accepted for presentation, consisting of 118 (72% oral/podium presentations and 46 (28% poster presentations. One hundred and thirty-three abstracts (81.1% came from African countries and 31 (18.9% from outside Africa.

  2. Quantum phase transitions

    Sachdev, S.

    1999-01-01

    Phase transitions are normally associated with changes of temperature but a new type of transition - caused by quantum fluctuations near absolute zero - is possible, and can tell us more about the properties of a wide range of systems in condensed-matter physics. Nature abounds with phase transitions. The boiling and freezing of water are everyday examples of phase transitions, as are more exotic processes such as superconductivity and superfluidity. The universe itself is thought to have passed through several phase transitions as the high-temperature plasma formed by the big bang cooled to form the world as we know it today. Phase transitions are traditionally classified as first or second order. In first-order transitions the two phases co-exist at the transition temperature - e.g. ice and water at 0 deg., or water and steam at 100 deg. In second-order transitions the two phases do not co-exist. In the last decade, attention has focused on phase transitions that are qualitatively different from the examples noted above: these are quantum phase transitions and they occur only at the absolute zero of temperature. The transition takes place at the ''quantum critical'' value of some other parameter such as pressure, composition or magnetic field strength. A quantum phase transition takes place when co-operative ordering of the system disappears, but this loss of order is driven solely by the quantum fluctuations demanded by Heisenberg's uncertainty principle. The physical properties of these quantum fluctuations are quite distinct from those of the thermal fluctuations responsible for traditional, finite-temperature phase transitions. In particular, the quantum system is described by a complex-valued wavefunction, and the dynamics of its phase near the quantum critical point requires novel theories that have no analogue in the traditional framework of phase transitions. In this article the author describes the history of quantum phase transitions. (UK)

    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

  6. Public health concerns associated with care of free-living birds.

    Whittington, Julia K

    2011-09-01

    Free-living birds are not only susceptible to certain infectious diseases; wild bird populations serve as reservoirs of several important diseases of public health concern. Bacterial and viral diseases endemic in populations of free-living birds such as tuberculosis, avian influenza, arboviral infections, and enteropathogens have been classified as emerging or reemerging. Providing care to wild avian patients increases the opportunity for direct contact with infected birds and the possibility of transmission of infectious disease to human handlers. Awareness of disease potential is critical to disease monitoring of wild populations and will allow for the implementation of precautionary measures when working with wild avian species. Biosecurity measures designed to minimize risk must be evaluated by individual facilities.

  7. Governmental costs and revenues associated with geothermal energy development in Imperial County. Special Publication 3241

    Energy Technology Data Exchange (ETDEWEB)

    Goldman, G.; Strong, D.

    1977-10-01

    This study estimates the cost and revenue impacts to local governments of three geothermal energy growth scenarios in Imperial County. The level of geothermal energy potential for the three development scenarios tested is 2,000, 4,000 and 8,000 MW--enough power to serve 270,000 to 1,000,000 people. The government agencies involved do not expect any substantial additional capital costs due to geothermal energy development; therefore, average costing techniques have been used for projecting public service costs and government revenues. The analysis of the three growth scenarios tested indicates that county population would increase by 3, 7 and 19 percent and assessed values would increase by 20, 60, and 165 percent for Alternatives No. 1, No. 2 and No. 3 respectively. Direct and indirect effects would increase new jobs in the county by 1,000, 3,000 and 8,000. Government revenues would tend to exceed public service costs for county and school districts, while city costs would tend to exceed revenues. In each of the alternatives, if county, cities and school districts are grouped together, the revenues exceed costs by an estimated $1,600 per additional person either directly or indirectly related to geothermal energy development in the operational stages. In the tenth year of development, while facilities are still being explored, developed and constructed, the revenues would exceed costs by an approximate $1,000 per additional person for each alternative. School districts with geothermal plants in their boundaries would be required by legislation SB 90 to reduce their tax rates by 15 to 87 percent, depending on the level of energy development. Revenue limits and school taxing methods will be affected by the Serrano-Priest decision and by new school legislation in process.

  8. For a public management of funds dedicated to nuclear dismantling: the TESEN (fund for the Energy transition and a fair phasing out nuclear), and its assignment to the financing of energy transition

    2013-01-01

    The report outlines that the cost of nuclear energy in France is largely under-assessed because of the under-evaluation of the future dismantling of nuclear installations and of the management of radioactive wastes. It outlines that provisions made for this dismantling are insufficient, opaque and very risky. This report proposes the creation of a fund independent from nuclear operators to make pay the actual cost of nuclear energy and reduce the French electrical dependence on this energy, to secure long-term financing to finance the dismantling, to bring the financing for the decades to come to finance energy transition, to finance energy transition at reasonable rates, and to clarify the governance for phasing out nuclear

    There is a growing body of evidence suggesting that certain foods may be addictive. Although evidence that nicotine is addictive generated support for anti-tobacco policies, little research has examined whether beliefs about the addictiveness of food are associated with support for policies to address overconsumption of nutritionally poor foods. U.S. adults (n=999) recruited from an online marketplace in February 2015 completed a survey. Using logistic regression, we examined the relationship between beliefs about the addictiveness of certain foods and support for twelve obesity-related policies while controlling for demographics, health status, political affiliation and ideology, beliefs about obesity, and attitudes towards food companies. We examined whether the association between beliefs about addictiveness and support for policies was consistent across other products and behaviors viewed as addictive (i.e., tobacco, alcohol, drugs, compulsive behaviors). In multivariable models, there was a significant association (OR; 95% CI) between beliefs about addictiveness and support for policies for compulsive behaviors (1.48; 1.26-1.74), certain foods (1.32; 1.14-1.53), drugs (1.23; 1.05-1.45), and alcohol (1.21; 1.08-1.36) but not for tobacco (1.11; 0.90-1.37). For foods, the association between beliefs about addictiveness and obesity-related policy support was the strongest between such beliefs and support for labels warning that certain foods may be addictive, industry reductions in salt and sugar, energy drink bans, and sugary drink portion size limits. Overall, believing that products/behaviors are addictive was associated with support for policies intended to curb their use. If certain foods are found to be addictive, framing them as such may increase obesity-related policy support. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Rats are ubiquitous in urban environments and, as established reservoirs for infectious pathogens, present a control priority for public health agencies. New York City (NYC harbors one of the largest rat populations in the United States, but surprising little study has been undertaken to define rat ecology across varied features of this urban landscape. More importantly, factors that may contribute to increased encounters between rats and humans have rarely been explored. Using city-wide records of rat sightings reported to the NYC Department of Health and Mental Hygiene, this investigation sought to identify sociodemographic, housing, and physical landscape characteristics that are associated with increased rat sightings across NYC census tracts. A hierarchical Bayesian conditional autoregressive Poisson model was used to assess these associations while accounting for spatial heterogeneity in the variance. Closer proximity to both subway lines and recreational public spaces was associated with a higher concentration of rat sightings, as was a greater presence of older housing, vacant housing units, and low education among the population. Moreover, these aspects of the physical and social landscape accurately predicted rat sightings across the city. These findings have identified specific features of the NYC urban environment that may help to provide direct control targets for reducing human–rat encounters.

  15. Elastic and anelastic anomalies associated with the antiferromagnetic ordering transition in wüstite, FexO

    The elastic and anelastic properties of three different samples of FexO have been determined in the frequency range 0.1-2 MHz by resonant ultrasound spectroscopy and in the range 0.1-50 Hz by dynamic mechanical analysis in order to characterize ferroelastic aspects of the magnetic ordering transition at TN ˜ 195 K. No evidence was found of separate structural and magnetic transitions but softening of the shear modulus was consistent with the involvement of bilinear coupling, λe4q, between a symmetry-breaking strain, e4, and a structural order parameter, q. Unlike a purely ferroelastic transition, however, C44 does not go to zero at the critical temperature, {T}_{{c}}^{\\ast }, due to the intervention of the magnetic ordering at a higher temperature. The overall pattern of behaviour is nevertheless consistent with what would be expected for a system with separate structural and magnetic instabilities, linear-quadratic coupling between the structural (q) and magnetic (m) driving order parameters, λqm2, and {T}_{{N}}\\gt {T}_{{c}}^{\\ast }. Comparison with data from the literature appears to confirm the same pattern in MnO and NiO, with a smaller difference between TN and {T}_{{c}}^{\\ast } in the former and a larger difference in the latter. Strong attenuation of acoustic resonances at high frequencies and a familiar pattern of attenuation at low frequencies suggest that twin walls in the rhombohedral phase have typical ferroelastic properties. Acoustic dissipation in the stability field of the cubic phase is tentatively attributed to anelastic relaxations of the defect ordered structure of non-stoichiometric wüstite or of the interface between local regions of wüstite and magnetite, with a rate controlling step determined by the diffusion of iron.

    Topographic images of [Fe(Htrz)₂(trz)](BF₄) nanoparticles were acquired across the first-order spin transition using variable-temperature atomic force microscopy (AFM) in amplitude modulation mode. These studies revealed a complex morphology of the particles consisting of aggregates of small nanocrystals, which expand, separate and re-aggregate due to the mechanical stress during the spin-state switching events. Both reversible (prompt or slow recovery) and irreversible effects (fatigue) on the particle morphology were evidenced and correlated with the spin crossover properties.

    To determine the consistency of conclusions/statements made in podium presentations at the annual meeting of the Orthopaedic Trauma Association (OTA) with those in subsequent full-text publications. Also, to evaluate the nature and consistency of study design, methods, sample sizes, results and assign a corresponding level of evidence. Abstracts of the scientific programs of the OTA from 1994 to 1997 (N = 254) were queried by using the PubMed database to identify those studies resulting in a peer-reviewed, full-text publication. Of the 169 articles retrieved, 137 studies were the basis of our study after the exclusion criteria were applied: non-English language, basic science studies, anatomic dissection studies, and articles published in non-peer-reviewed journals. Information was abstracted onto a data form: first from the abstract published in the final meeting program, and then from the published journal article. Information was recorded regarding study issues, including the study design, primary objective, sample size, and statistical methods. We provided descriptive statistics about the frequency of consistent results between abstracts and full-text publications. The results were recorded as percentages and a 95% confidence interval was applied to each value. Study results were recorded for the abstract and full-text publication comparing results and the overall conclusion. A level of scientific-based evidence was assigned to each full-text publication. The final conclusion of the study remained the same 93.4% of the time. The method of study was an observational case series 52% of the time and a statement regarding the rate of patient follow-up was reported 42% of the time. Of the studies published, 18.2% consisted of a sample size smaller than the previously presented abstract. When the published papers had their level of evidence graded, 11% were level I, 16% level II, 17% level III, and 56% level IV. Authors conclusions were consistent with those in full

    The decision of radiation oncology residents to pursue academic versus private practice careers plays a central role in shaping the present and future of the field, but factors that are potentially predictive of this decision are lacking. This study was performed to examine the role of several factors publicly available before residency on postresidency career choice, including preresidency peer-reviewed publications (PRPs), which have been associated with resident career choice in comparably competitive subspecialties such as neurosurgery. Using a combination of Internet searches, telephone interviews, and the 2015 Association of Residents in Radiation Oncology directory, a list of 2016 radiation oncology resident graduates was compiled, along with their postresidency career choice. PRP was defined as the number of PubMed publications encompassing the end of the calendar year (2010) in which residency applications were due; this number was then correlated with career choice. A total of 163 residents from 76 Accreditation Council for Graduate Medical Education-certified programs were examined: 78% were male, 22% were MDs/PhDs, and 79 graduates (48%) chose academic careers. Fifty-two percent of graduates had at least 1 PRP at the time of application to radiation oncology residency; 35% had more than 1 PRP. Regarding career choice, the difference between 0 and 1+ PRP was statistically significant (odds ratio, 3.3; P 1 PRP. Sex, PhD, or non-PhD dual degree status were not associated with career choice. Radiation oncology residency graduates with 1 or more PRPs at the time of residency application were roughly 2 times more likely to choose an academic career as their initial career choice than graduates with no preresidency PRPs. This information may prove useful to medical students, medical school advisors, and residency program directors and deserves further prospective investigation.

    1985-09-01

    Acceptance is described in both market and sensory research terminology and recent developments in the fields of applied psychology and physiology are examined for their pertinence to public acceptance of sucrose and its substitutes. Information on the function of sucrose in foods other than beverages is presented with emphasis on salivation as an acceptance factor and attention is drawn to its possible dental significance. Distinctions are made between the sweetening and bulking properties of sucrose and sugar substitutes. Factors having a bearing on the acceptance of sweet foods and the determination of their optimal sugar content are described in detail. While major decreases in sucrose intake in the US resulted from high-fructose corn-sweetener usage in soft drinks, no evidence is yet available to suggest that the use of sugar substitutes of the intense artificial sweetener type has caused any decrease in ordinary sugar consumption. Neither is the consumption of polyols (sorbitol, mannitol, xylitol) high enough in confectionery categories to cause any discernible decrease in sugar usage. The evidence suggests not so much that sugar substitutes may have stopped the growth in sucrose usage, but that new product categories such as diet foods and "sugarless' confections may have been created. These categories were never available to fermentable carbohydrate sweeteners and equivalence in acceptance to sucrose-sweetened products was not an important factor in their growth.(ABSTRACT TRUNCATED AT 250 WORDS)

    The results of studies carried out on public exposure contribution from naturally occurring radioactive materials (NORMS) in two open-pit mines in the Western and Ashanti regions of Ghana are reported. The studies were carried out under International Atomic Energy Agency-supported Technical Co-operation Project GHA/9/005. Measurements were made on samples of water, soil, ore, mine tailings and air using gamma spectrometry. Solid-state nuclear track detectors were used for radon concentration measurements. Survey was also carried out to determine the ambient gamma dose rate in the vicinity of the mines and surrounding areas. The effective doses due to external gamma irradiation, ingestion of water and inhalation of radon and ore dusts were calculated for the two mines. The average annual effective dose was found to be 0.30 +/- 0.06 mSv. The result was found to be within the levels published by other countries. The study provides a useful information and data for establishing a comprehensive framework to investigate other mines and develop guidelines for monitoring and control of NORMS in the mining industry and the environment as a whole in Ghana.

    The transition from paediatric to adult care is associated with poor clinical outcomes, increased costs and low patient and family satisfaction. However, little is known about health system strategies to streamline and safeguard care for youth transitioning to adult services. Moreover, the needs of children and youth are often excluded from broader health system reform discussions, leaving this population especially vulnerable to system 'disintegration'. (1) To explore the international policy profile of paediatric-to-adult care transitions, and (2) to document policy objectives, initiatives and outcomes for jurisdictions publicly committed to addressing transition issues. An international policy scoping review of all publicly available government documents detailing transition-related strategies was completed using a web-based search. Our analysis included a comparable cohort of nine wealthy Organisation for Economic Co-operation and Development (OECD) jurisdictions with Beveridge-style healthcare systems (deemed those most likely to benefit from system-level transition strategies). Few jurisdictions address transition of care issues in either health or broader social policy documents. While many jurisdictions refer to standardised practice guidelines, a few report the intention to use powerful policy levers (including physician remuneration and non-physician investments) to facilitate the uptake of best practice. Most jurisdictions do not address the policy infrastructure required to support successful transitions, and rigorous evaluations of transition strategies are rare. Despite the well-documented risks and costs associated with a poor transition from paediatric to adult care, little policy attention has been paid to this issue. We recommend that healthcare providers engage health system planners in the design and evaluation of system-level, policy-sensitive transition strategies.

    Full Text Available Methionine synthase (MTR is one of the key enzymes of folate pathway, which play a key role in the construction, repair, and methylation of DNA. In this study, an association of MTR A2756G gene transition with prostate cancer in men populations of Kashan-Iran was investigated by a case-control study and an in silico analysis. The 200 samples including 100 patients with prostate cancer, as case group and 100 healthy men, as control group included in this study. MTR-A2756G genotyping was performed by PCR-RFLP technique. Some in silico tools used to evaluate the effects of A2756G transition on the structure and function of MTR. Results showed that the AG genotype (OR: 2.4014, 95% CI: 1.3216-4.3636, P=0.0040, and GG genotype (OR: 3.6324, 95% CI: 1.2629-10.4475, P=0.0167 and G allele (OR: 2.0120, 95% CI: 1.3098-3.0905, P=0.0014 were associated with prostate cancer. In silico analysis showed that polymorphisms of the enzyme protein might change properties of MTR such as relative mutability and flexibility, which leads to alteration of stability and function of the enzyme. Based on the results, an MTR-A2756G polymorphism which changes activity and stability of the methionine synthase associated with prostate cancer in men. It is a preliminary study and is presenting data for future comprehensive study for making a clinical conclusion that this gene transition is a biomarker for susceptibility to prostate cancer.

    Greenland is a country in transition from a colonial past with subsistence hunting and fishing to an urban Nordic welfare state. Epidemiological transition from infectious to chronic diseases has been evident since the 1950s. Ninety percent of the population is Inuit. We studied three public health issues based on published literature, namely adverse childhood experiences, addictive behavior, and suicide; diet and obesity; and smoking. Alcohol consumption was high in the 1970s and 1980s with accompanying family and social disruption. This is still a cause of poor mental health and suicides in the generations most affected. The diet is changing from a traditional diet of fish and marine mammals to imported food including food items rich in sugar and fat from domestic animals, and the level of physical activity is decreasing with an ensuing epidemic rise in obesity. The prevalence of smoking is high at around 60% among both men and women and is only slowly decreasing. Smoking shows large social variation, and tobacco-related diseases are widespread. The diseases and conditions outlined above all contribute towards a low life expectancy at birth-69 years for men and 74 years for women in 2011-2015-compared with 78 and 84 years for men and women, respectively, on average in the European countries. The translation of government public health programs into local activities needs strengthening, and it must be realized that the improvement of public health is a long-term process.

    Early child development is a population determinant of physical, mental and social health. To know the base line situation prior to the implementation of "Chile grows with you" (Chile Crece Contigo) is key to its evaluation. To compare early child development and associated factors at baseline in pre-school children from public and private health sectors. The sample consisted of 1045 children aged 30-58 months, 52% male, and 671 from the public and 380 from the private sector of the metropolitan region in Chile were evaluated using Battelle Developmental Inventory-1 and a household interview of primary carer. Abnormal child development was found in 14.4% of children in the private sector compared to 30.4% in the public sector. There were no differences in adaptive area (26.3% vs 29.2%), but there were statistically significant differents in cognitive (8.8% vs 12.1%), social-personal (13.2% vs 32.5%), motor (19.2% vs 35.3%), and communication (19% vs 36.8%) development.

    While sex education is almost universal in U.S. schools, its content varies considerably. Topics such as abstinence, and basic information on HIV and other sexually transmitted diseases (STDs), are commonly taught; birth control and how to access STD and contraceptive services are taught less often. Factors potentially associated with these variations need to be examined. Data on 1,657 respondents to a 1999 national survey of teachers providing sex education in grades 7-12 were assessed for variation in topics covered. Logistic regression was used to ascertain factors associated with instruction on selected topics. The content of sex education varied by region and by instructors' approach to teaching about abstinence and contraception. For example, teaching abstinence as the only means of pregnancy and STD prevention was more common in the South than in the Northeast (30% vs. 17%). Emphasizing the ineffectiveness of contraceptives was less common in the Northeast (17%) than in other regions (27-32%). Instructors teaching that methods are ineffective and presenting abstinence as teenagers' only option had significantly reduced odds of teaching various skills and topics (odds ratios, 0.1-0.5). Instructors' approach to teaching about methods is a very powerful indicator of the content of sex education. Given the well-documented relationship between what teenagers learn about safer sexual behavior and their use of methods when they initiate sexual activity, sex education in all U.S. high schools should include accurate information about condoms and other contraceptives.

This research study was conducted using the database of the National Survey of Violence against Women that consisted of the responses of a total of 26 042 female users of health care services provided by the Mexican government health agencies. The Personal Health Scale (ESP per its initials in Spanish) was used to assess emotional distress. To measure violence a 19-item scale which explores different types of violence as well as severity was used. The relationship between emotional distress and gender violence was determined through a binary logistic regression model, as were economic status and demographic variables. One of the most important findings of this study is the high prevalence of emotional distress (15.3%) among women seeking health care services from the public sector and the relationship of such emotional distress with the experience of marital physical, psychological, and sexual violence. Factors associated with emotional distress among female users of health care services were age (26 and older); activity (laborer); working hours (71 hours a week or more); alcohol intake (greater intake); abuse during childhood (frequency and types of abuse); severity of marital violence (severe violence); socioeconomic status (very low SES); and type of dwelling (urban). The principal predictor of emotional distress was intimate partner abuse, especially in severe expression. The next predictor was violence in childhood. Taking into consideration these predictors it is recommended to use screening instruments to identify emotional distress and gender violence in health setting. It is important to design and implement attention and reference programs in public

    The research aimed to study the quality of cheap alcohol products in Poland. These included unrecorded alcohols (i.e., home-produced or illegally imported), estimated to constitute more than 25% of total consumption and fruit wines. A sample of alcohol products (n = 52) was collected from local markets and chemical analyses were conducted. The parameters studied were alcoholic strength, volatiles (methanol, acetaldehyde, and higher alcohols), ethyl carbamate, inorganic elements, and food additives including preservatives, colors, and sweeteners. The compositions of the beverages were then toxicologically evaluated using international standards. With the exception of 1 fortified wine, the unrecorded alcohols were home-produced fruit-derived spirits (moonshine) and spirits imported from other countries. We did not detect any nonbeverage surrogate alcohol. The unrecorded spirits contained, on average, 45% vol of alcohol. However, some products with considerably higher alcoholic strengths were found (up to 85% vol) with no labeling of the content on the bottles. These products may cause more pronounced detrimental health effects (e.g., liver cirrhosis, injuries, some forms of malignant neoplasms, alcohol use disorders, and cardiovascular disease) than will commercial beverages, especially as the consumer may be unaware of the alcohol content consumed. Fruit wines containing between 9.5 and 12.2% vol alcohol showed problems in terms of their additive content and their labeling (e.g., sulfites, sorbic acid, saccharin, and artificial colors) and should be subjected to stricter control. Regarding the other components investigated, the suspected human carcinogens, acetaldehyde and ethyl carbamate, were found at levels relevant to public health concerns. While acetaldehyde is a typical constituent of fermented beverages, ethyl carbamate was found only in home-produced unrecorded alcohols derived from stone fruits with levels significantly above international guidelines.

This study aimed to estimate the prevalence of exposure to simultaneous sedentary behavior domains and verify associated sociodemographic characteristics among technical and administrative servers of a Brazilian university. This is a cross-sectional epidemiological study carried out with 623 technical and administrative servers. Sedentary behavior was identified through a questionnaire in the following domains: commuting (active / passive, sitting time at work, daily time spent watching television and computer use (≥3 hours / day. Sociodemographic variables were age, sex and educational level. The prevalence of servers that had one, two, three and four simultaneous sedentary behavior was 28.4%, 43.2%, 22.5% and 4.3%, respectively. Women were more likely to have three sedentary behavior simultaneously (OR = 1.61, CI 95% = 1.02, 2.56. Servers with 9-11 years of schooling were less exposed to two (OR = 0.27, CI 95% = 0.17, 0.44, three (OR = 0.39, CI 95% = 0.23, 0.66 and four (OR = 0.22, CI 95% = 0.07; 0.69 sedentary behavior simultaneously and those over 12 years of schooling were less likely of having two (OR = 0.22, CI 95% = 0.10; 0.49 and three (OR = 0.15, CI 95% = 0.05, 0.46 sedentary behavior simultaneously. More than half of servers have two sedentary behavior during the week. Having sedentary behavior in more than one domain simultaneously was associated with sex and educational level.

    The study aimed to establish whether family characteristics and the health behaviour and illnesses of parents and children are associated with public health nurses' (PHNs') concerns about children's physical health and psychosocial development in the context of health examinations. Factors affecting children's health and well-being should be identified as early as possible to provide children and families appropriate support. In 2007-2009, a cross-sectional study in Finland collected information about PHNs' concerns, children's health and well-being as well as the background factors affecting them during health examinations of preschool-age children and school-aged children (n = 4795). Associations between family characteristics, parents' and children's behaviour and diseases, and PHNs' concerns were assessed using logistic regression analysis. Overweight in children, the long-term illnesses of both children and parents, and parental smoking were the factors most strongly associated with PHNs' concerns about a child's physical health whereas non-nuclear family types, the father's low educational level and unemployment, the child's lack of sleep, and bullying were associated with concerns about the child's psychosocial development. The connections found demonstrate that health examinations should address factors that affect the whole family's well-being so as to comprehensively promote children's health, growth and development. © 2016 John Wiley & Sons Australia, Ltd.

  20. Native Hydrophobic Binding Interactions at the Transition State for Association between the TAZ1 Domain of CBP and the Disordered TAD-STAT2 Are Not a Requirement.

    A significant fraction of the eukaryotic proteome consists of proteins that are either partially or completely disordered under native-like conditions. Intrinsically disordered proteins (IDPs) are common in protein-protein interactions and are involved in numerous cellular processes. Although many proteins have been identified as disordered, much less is known about the binding mechanisms of the coupled binding and folding reactions involving IDPs. Here we have analyzed the rate-limiting transition state for binding between the TAZ1 domain of CREB binding protein and the intrinsically disordered transactivation domain of STAT2 (TAD-STAT2) by site-directed mutagenesis and kinetic experiments (Φ-value analysis) and found that the native protein-protein binding interface is not formed at the transition state for binding. Instead, native hydrophobic binding interactions form late, after the rate-limiting barrier has been crossed. The association rate constant in the absence of electrostatic enhancement was determined to be rather high. This is consistent with the Φ-value analysis, which showed that there are few or no obligatory native contacts. Also, linear free energy relationships clearly demonstrate that native interactions are cooperatively formed, a scenario that has usually been observed for proteins that fold according to the so-called nucleation-condensation mechanism. Thus, native hydrophobic binding interactions at the rate-limiting transition state for association between TAD-STAT2 and TAZ1 are not a requirement, which is generally in agreement with previous findings on other IDP systems and might be a common mechanism for IDPs.

    The central focus of this thesis is the question of whether public investment in transport infrastructure contributes positively to Malaysia’s economic growth and welfare. Although there are strong analytical reasons to believe that public investment spending is one of the important variables that influence growth, there remains significant uncertainty about its actual degree of influence. In Malaysia, whenever there is a collapse in domestic demand, government spending becomes an important m...

    Contracting non-governmental organizations (NGOs) has been shown to increase health service delivery output considerably over relatively short time frames in low-income countries, especially when applying performance-related pay as a stimulus. A key concern is how to manage the transition back to government-operated systems while maintaining health service delivery output levels. In this paper we describe and analyse the transition from NGO-managed to government-managed health services over a 3-year period in a health district in Cambodia with a focus on the level of health service delivery. Data are derived from four sources, including cross-sectional surveys and health management and financial information systems. The transition was achieved by focusing on all the building blocks of the health care system and ensuring an acceptable financial remuneration for the staff members of contracted health facilities. The latter was attained through performance subsidies derived from financial commitment by the central government, and revenue from user fees. Performance management had a crucial role in the gradual handover of responsibilities. Not all responsibilities were handed back to government over the case study period-notably the development of performance indicators and targets and the performance monitoring.

    In this paper, we evaluate the association of the human methylenetetrahydrofolate reductase (MTHFR)-G1793A transition with male infertility using a case-control study, a meta-analysis and an in silico analysis. In the case-control study, 308 blood samples (169 infertile and 139 fertile men) were collected. MTHFR-G1793A genotyping was performed by PCR-RFLP. The study revealed a significant protective association between the GA genotype (OR: 0.3737, 95%CI: 0.1874-0.7452, p = 0.0052) and A allele (OR: 0.4266, 95%CI: 0.2267-0.8030, p = 0.0083) with male infertility. Meta-analysis showed that the G1793A transition might be a protective mutation against male infertility in both A vs. G (OR: 0.608, 95%CI: 0.466-0.792, p silico-analysis revealed that although G1793A could not make fundamental changes in the function and structure of MTHFR, it could modify the structure of the mRNA (Distance =0.1809, p = 0.1095; p < 0.2 is significant). The results suggest that G1793A substitution might be a protective genetic factor against male infertility. However, further case-control studies are required to provide a more robust conclusion.

    We used the Submillimeter Array to image the SiO maser emission in the v=1, J=5-4 transition associated with the peculiar red supergiant VY Canis Majoris. We identified seven maser components and measured their relative positions and linear polarization properties. Five of the maser components are coincident to within about 150 mas (~200 AU at the distance of 1.5 kpc); most of them may originate in the circumstellar envelope at a radius of about 50 mas from the star along with the SiO masers in the lowest rotational transitions. Our measurements show that two of the maser components may be offset from the inner stellar envelope (at the 3 σ level of significance) and may be part of a larger bipolar outflow associated with VY CMa identified by Shinnaga et al. The strongest maser feature at a velocity of 35.9 km s-1 has a 60% linear polarization, and its polarization direction is aligned with the bipolar axis. Such a high degree of polarization suggests that maser inversion is due to radiative pumping. Five of the other maser features have significant linear polarization.

    Resonant Ultrasound Spectroscopy has been used to characterize elastic softening and a variety of new acoustic dissipation processes associated with the Pm{bar 3}m {leftrightarrow} R{bar 3}c transition in single crystal and ceramic samples of LaAlO{sub 3}. Softening of the cubic structure ahead of the transition point is not accompanied by an increase in dissipation but follows different temperature dependences for the bulk modulus, 1/3(C{sub 11} + 2C{sub 12}), and the shear components 1/2(C{sub 11}-C{sub 12}) and C{sub 44} as if the tilting instability contains two slightly different critical temperatures. The transition itself is marked by the complete disappearance of resonance peaks (superattenuation), which then reappear below {approx}700 K in spectra from single crystals. Comparison with low frequency, high stress data from the literature indicate that the dissipation is not due to macroscopic displacement of needle twins. An alternative mechanism, local bowing of twin walls under low dynamic stress, is proposed. Pinning of the walls with respect to this displacement process occurs below {approx}350 K. Anelasticity maps, analogous to plastic deformation mechanism maps, are proposed to display dispersion relations and temperature/frequency/stress fields for different twin wall related dissipation mechanisms. An additional dissipation process, with an activation energy of 43 {+-} 6 kJ.mole{sup -1}, occurs in the vicinity of 250 K. The mechanism for this is not known, but it is associated with C{sub 44} and therefore appears to be related in some way to the cubic {leftrightarrow} rhombohedral transition at {approx}817 K. Slight softening in the temperature interval {approx}220 {yields} 70 K of resonance peaks determined by shear elastic constants hints at an incipient E{sub g} ferroelastic instability in LaAlO{sub 3}. The softening interval ends with a further dissipation peak at {approx} 60 K, the origin of which is discussed in terms of freezing of atomic

    Sulfur dioxide (SO(2)) has been associated with increased mortality and morbidity, but only few studies were conducted in Asian countries. Previous studies suggest that SO(2) may have adverse health effects independent of other pollutants. In the Public Health and Air Pollution in Asia (PAPA) project, the short-term associations between ambient sulfur dioxide (SO(2)) and daily mortality were examined in Bangkok, Thailand, and three Chinese cities: Hong Kong, Shanghai, and Wuhan. Poisson regression models incorporating natural spline smoothing functions were used to adjust for seasonality and other time-varying covariates. Effect estimates were obtained for each city and then for the cities combined. The impact of alternative model specifications, such as lag structure of pollutants and degree of freedom (df) for time trend, on the estimated effects of SO(2) were also examined. In both individual-city and combined analysis, significant effects of SO(2) on total non-accidental and cardiopulmonary mortality were observed. An increase of 10 microg/m(3) of 2-day moving average concentrations of SO(2) corresponded to 1.00% [95% confidence interval (CI), 0.75-1.24], 1.09% (95% CI, 0.71-1.47), and 1.47% (95% CI, 0.85-2.08) increase of total, cardiovascular and respiratory mortality, respectively, in the combined analysis. Sensitivity analyzes suggested that these findings were generally insensitive to alternative model specifications. After adjustment for PM(10) or O(3), the effect of SO(2) remained significant in three Chinese cities. However, adjustment for NO(2) diminished the associations and rendered them statistically insignificant in all four cities. In conclusion, ambient SO(2) concentration was associated with daily mortality in these four Asian cities. These associations may be attributable to SO(2) serving as a surrogate of other substances. Our findings suggest that the role of outdoor exposure to SO(2) should be investigated further in this region. (c) 2010

    Many parents rely on emergency services to deal with their children's dental problems, mostly pain and infection associated with dental caries. This cross-sectional study analyzed the factors associated with not doing an oral procedure in preschoolers with toothache attending public dental emergency services. Data were obtained from the clinical files of preschoolers treated at all nine dental emergency centers in Goiania, Brazil, in 2011. Data were children's age and sex, involved teeth, oral procedures, radiography request, medications prescribed and referrals. A total of 531 files of children under 6 years old with toothache out of 1,108 examined were selected. Children's mean age was 4.1 (SD 1.0) years (range 1-5 years) and 51.6% were girls. No oral procedures were performed in 49.2% of cases; in the other 50.8%, most of the oral procedures reported were endodontic intervention and temporary restorations. Primary molars were involved in 48.4% of cases. With the exception of "sex", the independent variables tested in the regression analysis significantly associated with non-performance of oral procedures: age (OR 0.7; 95% CI 0.5-0.8), radiography request (OR 3.8; 95% CI 1.7-8.2), medication prescribed (OR 7.5; 95% CI 4.9-11.5) and patient referred to another service (OR 5.7; 3.0-10.9). Many children with toothache received no oral procedure for pain relief.

    To analyze the evolution of the prevalence in intimate partner violence during the years 2003 and 2006 in Mexico, identifying factors associated with its severity, comparing our results with findings from 2003. Data from the Encuesta Nacional de Violencia contra las Mujeres (ENVIM 2006) was used; it has urban-rural national representation of female users of Mexican public health services. A total of 22,318 women above 14 years of age were interviewed. A multinomial logistic regression model was adjusted. The dependent variable was the Index of Intimate Partner Abuse. Intimate partner abuse increased 17% in comparison to the year 2003. Women's personal history of childhood abuse (ORA= 5.12, 95% CI4.15-6.30) and rape (ORA = 3.5, 95% CI = 2.66-4.62) were the most important women's factors that were found associated with severe violence. Male partner's daily alcohol consumption increased eleven fold the possibility of severe violence; higher disagreement with traditional female gender roles and higher education of both partners were protective factors. Factors associated with violence and their severities were consistent with findings reported in 2003. Intimate partner violence is a highly prevalent social problem which requires comprehensive strategies supporting empowerment of women through higher education, early detection and care of those battered, as well as structured interventions to prevent violence in future generations.

  14. Deformation associated to exhumation of serpentinized mantle rocks in a fossil Ocean Continent Transition: The Totalp unit in SE Switzerland

    Although the exhumation of ultramafic rocks in slow and ultraslow spreading Mid-Ocean Ridges and Ocean Continent Transitions (OCTs) has been extensively investigated, the deformation processes related to mantle exhumation are poorly constrained. In this paper we present a new geological map and a section across the exhumed serpentinized peridotites of the Totalp unit near Davos (SE Switzerland), and we propose that the Totalp unit is formed by two Alpine thrust sheets. Geological mapping indicates local exposure of a paleo-seafloor that is formed by an exhumed detachment surface and serpentinized peridotites. The top of the exhumed mantle rocks is made of ophicalcites that resulted from the carbonation of serpentine under static conditions at the seafloor. The ophicalcites preserve depositional contacts with Upper Jurassic to Lower Cretaceous pelagic sediments (Bernoulli and Weissert, 1985). These sequences did not exceed prehnite-pumpellyite metamorphic facies conditions, and locally escaped Alpine deformation. Thin mylonitic shear zones as well as foliated amphibole-bearing ultramafic rocks have been mapped. The age of these rocks and the link with the final exhumation history are yet unknown but since amphibole-bearing ultramafic rocks can be found as clasts in cataclasites related to the detachment fault, they pre-date detachment faulting. Our petrostructural study of the exhumed serpentinized rocks also reveals a deformation gradient from cataclasis to gouge formation within 150 m in the footwall of the proposed paleo-detachment fault. This deformation postdates serpentinization. It involves a component of plastic deformation of serpentine in the most highly strained intervals that has suffered pronounced grain-size reduction and a polyphase cataclastic overprint.

    The purpose of our study was to identify the perfusion MRI (pMRI) algorithm which yields a volume of hypoperfused tissue that best correlates with the acute clinical deficit as quantified by the NIH Stroke Scale (NIHSS) and therefore reflects critically hypoperfused tissue. A group of 20 patients with a first acute stroke and stroke MRI within 24 h of symptom onset were retrospectively analyzed. Perfusion maps were derived using four different algorithms to estimate relative mean transit time (rMTT): (1) cerebral blood flow (CBF) arterial input function (AIF)/singular voxel decomposition (SVD); (2) area peak; (3) time to peak (TTP); and (4) first moment method. Lesion volumes based on five different MTT thresholds relative to contralateral brain were compared with each other and correlated with NIHSS score. The first moment method had the highest correlation with NIHSS (r=0.79, P<0.001) followed by the AIF/SVD method, both of which did not differ significantly from each other with regard to lesion volumes. TTP and area peak derived both volumes, which correlated poorly or only moderately with NIHSS scores. Data from our pilot study suggest that the first moment and the AIF/SVD method have advantages over the other algorithms in identifying the pMRI lesion volume that best reflects clinical severity. At present there seems to be no need for extensive postprocessing and arbitrarily defined delay thresholds in pMRI as the simple qualitative approach with a first moment algorithm is equally accurate. Larger sample sizes which allow comparison between imaging and clinical outcomes are needed to refine the choice of best perfusion parameter in pMRI. (orig.)

    Depression in adolescents is a matter of concern because of its high prevalence, potential recurrence and impairment of functioning in the affected individual. The study sought to determine the prevalence of depressive symptoms among adolescents in Nairobi (Kenya) public secondary schools; make a comparison between day and boarding students; and identify associated factors in this population. A random sample of school going adolescents was taken from a stratified sample of 17 secondary schools out of the 49 public secondary schools in Nairobi province. The sample was stratified to take into account geographical distribution, day and boarding schools, boys only, girls only and mixed (co-education) schools in the capital city of Kenya. Self administered instruments (EMBU and CDI) were used to measure perceived parental behaviour and levels of depression in a total of 1,276 students excluding those who had no living parent. The prevalence of clinically significant depressive symptoms was 26.4%. The occurrence was higher in girls than it was in boys p<0.001. Students in boarding schools had more clinically significant depressive symptoms compared to day students (p=0.01). More girls exhibited suicidal behaviour than boys (p<0.001). There was a significant correlation between depressive symptoms and suicidal behaviour (p<0.001). CDI scores correlated positively with age (p<0.001) with an increase in CDI score with unit increase in age among students 14-17 years old, perceived rejecting maternal parenting behaviour (p<0.001), perceived no emotional attachment paternal behaviour (p<0.001), perceived no emotional attachment maternal behaviour (p<0.001), and perceived under protective paternal behaviour (p=0.005). Perceived maladaptive parental behaviours are substantially associated with the development of depressive symptoms and suicidal behaviour in children.

This study aimed to investigate the role of lncRNA colon cancer-associated transcript 2 (CCAT2 in the progression of HCC. Quantitative real-time polymerase chain reaction analysis confirmed that CCAT2 was upregulated in HCC cell lines and cancerous tissues compared with normal liver cell line and adjacent normal tissue samples. The level of CCAT2 was positively associated with tumor–node–metastasis stages and vessel invasion. Survival analyses revealed that high CCAT2 expression predicted poor prognostic outcomes, serving as an independent prognostic factor for HCC patients. Patients with high CCAT2 expression had a 1.849-fold increased risk of death compared with those with low CCAT2 expression. Moreover, we also found that knockdown of CCAT2 expression reduced cell migration and invasion in vitro. We further demonstrated that CCAT2 played a key role in enhancing the epithelial–mesenchymal transition (EMT through the regulation of vimentin, E-cadherin and transcription factor snail2 expression. Taken together, our findings showed that high CCAT2 expression is associated with poor survival in HCC patients. CCAT2 promotes HCC progression by regulating Snail2-induced EMT. CCAT2 may be a prognostic biomarker and therapeutic target for HCC. Keywords: long non-coding RNA, CCAT2, hepatocellular carcinoma, epithelial–mesenchymal transition, survival

    Coleman's focal theory, developed in relation to adolescents in the general population, appears to offer some explanation for the poor educational achievement and social exclusion of care leavers, but has been little tested empirically. This paper revisits data from two studies of care-experienced young people aged 18-25, drawing on qualitative interviews in the UK and four other European countries, to see if focal theory would have helped to predict their educational progression or otherwise. The lives of research participants were found to be characterised by disruptions and uncertainty, with multiple challenges confronting them in quick succession, making it hard for them to pace their transitions as, according to focal theory, other young people do. Findings suggest that the theory could be used to inform policy designed to improve educational outcomes and should be incorporated into training for those responsible for supporting care leavers through their transition to adulthood.

    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 Since cattle are a major source of food and the cattle industry engages people from farms to processing plants and meat markets, it is conceivable that beef-products contaminated with Campylobacter spp. would pose a significant public health concern. To better understand the epidemiology of cattle-associated Campylobacter spp. in the USA, we characterized the prevalence, genotypic and phenotypic properties of these pathogens. Campylobacter were detected in 181 (19.2% out of 944 fecal samples. Specifically, 71 C. jejuni, 132 C. coli, and 10 other Campylobacter spp. were identified. The prevalence of Campylobacter varied regionally and was significantly (P<0.05 higher in fecal samples collected from the South (32.8% as compared to those from the North (14.8%, Midwest (15.83%, and East (12%. Pulsed Field Gel Electrophoresis (PFGE analysis showed that C. jejuni and C. coli isolates were genotypically diverse and certain genotypes were shared across two or more of the geographic locations. In addition, 13 new C. jejuni and two C. coli sequence types (STs were detected by Multi Locus Sequence Typing (MLST. C. jejuni associated with clinically human health important sequence type, ST-61 which was not previously reported in the USA, was identified in the present study. Most frequently observed clonal complexes (CC were CC ST-21, CC ST-42, and CC ST-61, which are also common in humans. Further, the cattle associated C. jejuni strains showed varying invasion and intracellular survival capacity; however, C. coli strains showed a lower invasion and intracellular survival potential compared to C. jejuni strains. Furthermore, many cattle associated Campylobacter isolates showed resistance to several antimicrobials including ciprofloxacin, erythromycin, and gentamicin. Taken together, our results highlight the importance of cattle as a potential reservoir for clinically important Campylobacter.

    Home baseline and laboratory stressor (Trier Social Stress Test for Children) measures of salivary cortisol were obtained from 82 participants (40 girls) aged 9, 11, 13, and 15 years. Measures of pubertal development, self-reported stress, parent reports of child depressive symptoms and fearful temperament, and cardiac measures of sympathetic and parasympathetic activity were also obtained. Significant increases in the home cortisol baselines were found with age and pubertal development. Cortisol stress reactivity differed by age group with 11-year-olds and 13-year-old boys showing blunted reactivity and 9-year-olds, 13-year-old girls, and 15-year-olds showing significant cortisol reactions. Cortisol reactivity correlated marginally with sexual maturation. Measures of sympathetic activity revealed increased sympathetic modulation with age. Higher sympathetic tone was associated with more fearful temperament, whereas greater cortisol reactivity was associated with more anxious and depressed symptoms for girls. The importance of these findings for the hypothesis that puberty-associated increases in hypothalamic-pituitary-adrenal axis activity heightens the risk of psychopathology is discussed.

    Exosomes derived from solid tumor cells are involved in immune suppression, angiogenesis, and metastasis, but the role of leukemia-derived exosomes has been less investigated. The pathogenesis of chronic lymphocytic leukemia (CLL) is stringently associated with a tumor-supportive microenvironment and a dysfunctional immune system. Here, we explore the role of CLL-derived exosomes in the cellular and molecular mechanisms by which malignant cells create this favorable surrounding. We show that CLL-derived exosomes are actively incorporated by endothelial and mesenchymal stem cells ex vivo and in vivo and that the transfer of exosomal protein and microRNA induces an inflammatory phenotype in the target cells, which resembles the phenotype of cancer-associated fibroblasts (CAFs). As a result, stromal cells show enhanced proliferation, migration, and secretion of inflammatory cytokines, contributing to a tumor-supportive microenvironment. Exosome uptake by endothelial cells increased angiogenesis ex vivo and in vivo, and coinjection of CLL-derived exosomes and CLL cells promoted tumor growth in immunodeficient mice. Finally, we detected α-smooth actin–positive stromal cells in lymph nodes of CLL patients. These findings demonstrate that CLL-derived exosomes actively promote disease progression by modulating several functions of surrounding stromal cells that acquire features of cancer-associated fibroblasts.

    Federal regulations require the United States Forest Service (USFS) to integrate public input and values into decisions concerning land and resource management planning. The USFS has typically relied on traditional methods of involving the public, whereby public access and input to policy development are unilaterally controlled by the agency. Because of the highly political nature of land and resource management planning, such technocratic forms of public involvement and decision-making appear to be proving ineffective. This paper describes and evaluates two public involvement programs associated with the Ouachita National Forest`s (ONF) lengthy forest planning process. The research consisted of personal interviews with key program leaders and knowledgeable citizen participants, collection of secondary data, and a survey of citizen participants. Because of controversial planning decisions made during an initial planning process, the ONF was forced to re-enter the planning process in order to address unresolved planning issues and to conduct a more effective public involvement program. The supplemental planning process also resulted in a considerable degree of public contention. The survey revealed that although citizen participants were somewhat more satisfied with the supplemental public involvement program relative to the initial program, neither program was viewed as satisfactory. The findings of the study suggest that in order to be more effective, USFS public involvement programs should be more responsive to public concerns and conducted in adherence to principles of collaborative planning.

All states in the USA and the District of Columbia for which data were available (n=42). Homicide rates for each state were abstracted from the US Department of Justice Federal Bureau of Investigation's Uniform Crime Reporting. After adjusting for potential confounding variables, we found that every $10 000 increase in spending per person living in poverty was associated with 0.87 fewer homicides per 100 000 population or approximately a 16% decrease in the average homicide rate (estimate=-0.87, SE=0.15, phomicide rates at the state level. Although we cannot infer causality from this research, such spending may provide promising avenues for homicide reduction in the USA, particularly among states with lower levels of poverty. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The aims of this study were to evaluate zinc, copper, and iron concentrations in the transitory milk of Korean lactating mothers and to investigate the relationship between these concentrations and maternal diet. Human milk samples were collected between 5 and 15 days postpartum from 96 healthy, lactating mothers in postpartum care centers in Seoul, Korea. Dietary intake during lactation was determined based on a 3-day dietary record. The mean zinc, copper, and iron concentrations in the human milk samples collected were 3.88 ± 1.74 mg/L, 0.69 ± 0.25 mg/L, and 5.85 ± 8.53 mg/L, respectively. The mothers who consumed alcoholic beverages during pregnancy had tended to have lower concentrations of zinc and copper, as well as significantly lower concentrations of iron, in their milk (p < 0.047). In contrast, the mothers who took daily supplements had much higher iron concentrations in their milk (p = 0.002). Dietary intakes of zinc, copper, and iron during lactation did not affect the concentrations of zinc, copper, and iron in the milk samples analyzed. Intakes of vitamin C, selenium, and iodine were associated with the concentration of copper in the milk samples analyzed, and consumption of food categorized as 'meat and meat products' was positively associated with the concentration of zinc. Consumption of rice was the top contributor to the concentrations of all three minerals. In conclusion, associations between maternal diet and nutrient concentrations in transitory human milk can provide useful information, particularly in regard to infant growth. PMID:26839873

    The abrupt transition to heightened poliomyelitis epidemicity in England and Wales, 1947-1957, was associated with a profound change in the spatial dynamics of the disease. Drawing on the complete record of poliomyelitis notifications in England and Wales, we use a robust method of spatial epidemiological analysis (swash-backwash model) to evaluate the geographical rate of disease propagation in successive poliomyelitis seasons, 1940-1964. Comparisons with earlier and later time periods show that the period of heightened poliomyelitis epidemicity corresponded with a sudden and pronounced increase in the spatial rate of disease propagation. This change was observed for both urban and rural areas and points to an abrupt enhancement in the propensity for the geographical spread of polioviruses. Competing theories of the epidemic emergence of poliomyelitis in England and Wales should be assessed in the light of this evidence.

  19. Transition radiation and transition scattering

    International Nuclear Information System (INIS)

    Ginzburg, V.L.

    1982-01-01

    Transition radiation is a process of a rather general character. It occurs when some source, which does not have a proper frequency (for example, a charge) moves at a constant velocity in an inhomogeneous and (or) nonstationary medium or near such a medium. The simplest type of transition radiation takes place when a charge crosses a boundary between two media (the role of one of the media may be played by vacuum). In the case of periodic variation of the medium, transition radiation possesses some specific features (resonance transition radiation or transition scattering). Transition scattering occurs, in particular, when a permittivity wave falls onto an nonmoving (fixed) charge. Transition scattering is closely connected with transition bremsstrahlung radiation. All these transition processes are essential for plasma physics. Transition radiation and transition scattering have analogues outside the framework of electrodynamics (like in the case of Vavilov-Cherenkov radiation). In the present report the corresponding range of phenomena is elucidated, as far as possible, in a generally physical aspect. (Auth.)

    Stress contributes to the development and maintenance of substance use disorders (SUD), with some research suggesting that the impact of stress on SUD is greater in women. However, this has yet to be evaluated in a national dataset, across major substances of abuse. Using data from the newly available U.S. National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; Wave 3; n =36,309) we evaluated relationships among past year stressful life events (0 or 1 vs. 2+ events, range 0-16) and gender, and their association with transitions (new vs. absent cases; ongoing vs. remitted cases) in Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) alcohol use disorder (AUD), tobacco use disorder (TUD), cannabis use disorder (CUD), and nonmedical prescription opioid use disorder (OUD) diagnoses. Having 2 or more stressful life events in the past year increased the odds of having a new AUD, TUD, CUD, and OUD (OR=3.14, 2.15, 5.52, and 3.06, respectively) or ongoing AUD, TUD, and CUD (OR=2.39, 2.62, and 2.95, respectively) compared to 0 or 1 stressful life event. A stress by gender interaction for new vs. absent AUD demonstrated that having 2 or more stressful life events was associated with increased odds of new AUD in men (OR=2.51) and even greater odds of new AUD in women (OR=3.94). Results highlight that stress is a robust factor in both men and women with new or ongoing substance use disorders, and that effective treatments for substance use should consider the role of stress in addiction etiology and maintenance. There was little evidence for gender differences in the role of stress on transitions in substance use disorders, except for the onset of alcohol use disorders. Given that rates of alcohol use disorders are increasing in women; the impact of stress needs to be considered.

    Bystander cardiopulmonary resuscitation (CPR) is an important factor associated with improved survival rates and neurologic prognoses in cases of out-of-hospital cardiac arrest. We assessed how factors related to CPR education including timing of education, period from the most recent education session, and content, affected CPR willingness. In February 2012, trained interviewers conducted an interview survey of 1,000 Daegu citizens through an organized questionnaire. The subjects were aged ≥19 years and were selected by quota sampling. Their social and demographic characteristics, as well as CPR and factors related to CPR education, were investigated. Chi-square tests and multivariate logistic regression analyses were used to evaluate how education-related factors affected the willingness to perform CPR. Of total 1,000 cases, 48.0% were male. The multivariate analyses revealed several factors significantly associated with CPR willingness: didactic plus practice group (adjusted odds ratio [AOR], 3.38; 95% confidence interval [CI], 2.3 to 5.0), group with more than four CPR education session (AOR, 7.68; 95% CI, 3.21 to 18.35), interval of less than 6 months from the last CPR education (AOR, 4.47; 95% CI 1.29 to 15.52), and education with automated external defibrillator (AOR, 5.98; 95% CI 2.30 to 15.53). The following were associated with increased willingness to perform CPR: practice sessions and automated electrical defibrillator training in public CPR education, more frequent CPR training, and shorter time period from the most recent CPR education sessions.

    Several studies have shown that parity is associated with oral health problems such as tooth loss and dental caries. In Japan, however, no studies have examined the association. The purpose of this study was to determine whether parity is related to dentition status, including the number of teeth present, dental caries and filled teeth, and the posterior occlusion, in a Japanese population by comparing women with men. A total of 1,211 subjects, who participated both in the Japan Public Health Center-Based (JPHC) Study Cohort I in 1990 and the dental survey in 2005, were used for the study. Information on parity or number of children was collected from a self-completed questionnaire administered in 1990 for the JPHC Study Cohort I, and health behaviors and clinical dentition status were obtained from the dental survey in 2005. The association between parity or number of children and dentition status was analyzed, by both unadjusted-for and adjusted-for socio-demographic and health behavioral factors, using a generalized linear regression model. Parity is significantly related to the number of teeth present and n-FTUs (Functional Tooth Units of natural teeth), regardless of socio-demographic and health behavioral factors, in female subjects. The values of these variables had a significantly decreasing trend with the rise of parity: numbers of teeth present (p for trend = 0.046) and n-FTUs (p for trend = 0.026). No relationships between the number of children and dentition status were found in male subjects. Higher-parity women are more likely to lose teeth, especially posterior occluding relations. These results suggest that measures to narrow the discrepancy by parity should be taken for promoting women's oral health. Delivery of appropriate information and messages to pregnant women as well as enlightenment of oral health professionals about dental management of pregnant women may be an effective strategy.

    For several reasons, spacecraft are constructed in so-called clean rooms. Particles could affect the function of spacecraft instruments, and for missions under planetary protection limitations, the biological contamination has to be restricted as much as possible. The proper maintenance of clean rooms includes, for instance, constant control of humidity and temperature, air filtering, and cleaning (disinfection) of the surfaces. The combination of these conditions creates an artificial, extreme biotope for microbial survival specialists: spore formers, autotrophs, multi-resistant, facultative, or even strictly anaerobic microorganisms have been detected in clean room habitats. Based on a diversity study of European and South-American spacecraft assembly clean rooms, the European Space Agency (ESA) has initialized and funded the creation of a public library of microbial isolates. Isolates from three different European clean rooms, as well as from the final assembly and launch facility in Kourou (French Guiana), have been phylogenetically analyzed and were lyophilized for long-term storage at the German Culture Collection facilities in Brunswick, Germany (Leibniz-Institut DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen). The isolates were obtained by either following the standard protocol for the determination of bioburden on, and around, spacecraft or the use of alternative cultivation strategies. Currently, the database contains 298 bacterial strains. Fifty-nine strains are Gram-negative microorganisms, belonging to the α-, β- and γ-Proteobacteria. Representatives of the Gram-positive phyla Actinobacteria, Bacteroidetes/Chlorobi, and Firmicutes were subjected to the collection. Ninety-four isolates (21 different species) of the genus Bacillus were included in the ESA collection. This public collection of extremotolerant microbes, which are adapted to a complicated artificial biotope, provides a wonderful source for industry and research focused on

    Full Text Available Globally, neonatal death accounts about 44% of child death in 2013. Ethiopia is one of the ten countries with the highest number of neonatal death. Worldwide, more than 43% of deaths among under five year children is contributed by neonates. Half of the neonatal death occur in the first day of life. Recommendations about newborn care practices may conflict with local beliefs and practices. So, it is important to understand the existing newborn care practice and factors affecting it in order to take interventions so as to decrease neonatal death.To assess magnitude of essential neonatal care utilization and associated factors among women visiting public health facilities in Aksum Town, Tigray, Northern Ethiopia, 2015.Facility based cross sectional study was conducted from December 30, 2015 to January 31, 2016.The sampled population are 423 women who gave live births within the last 6 months prior to data collection. Systematic random sampling technique was employed. Data were entered, coded and cleaned using Epi info version 7, and SPSS Version 21 software was used for analysis. Both bivariable and multivariable logistic regression models were used to determine factors associated with essential neonatal care utilization. Variables with P-value <0.2 in the bivariable logistic regression model were included in to multivariable logistic regression model, and finally variables with P-value <0.05 were considered as independent factors. Odds ratio was used to measure strength of association at 95% confidence level.A total of 423 mothers included in the study. Prevalence of safe cord care, optimal breast feeding, thermal care and baby received Tetracycline eye ointment and vaccine at birth were 42.8%, 63.1%, 32.6% and 44.7% among the respondents respectively. Only 113(26.7% of the participants fulfilled essential new born care practice. Occupation, parity and counseling on essential new born care during delivery were significantly associated with

    The aim was to investigate which individual, psychosocial and physical neighborhood environmental factors associate with children's switch to or maintenance of active/passive transport to school and to leisure time destinations during the transition from primary to secondary school. Children (n = 313) filled out a questionnaire in the last year of primary school and 2 years later to assess socio-demographic characteristics and self-reported transport. One of their parents completed a questionnaire to assess parental perceptions of psychosocial and physical neighborhood environmental factors. The increase of the home-school distance was significantly associated with children's switch to or maintenance of passive transport to school compared to a switch to (OR = 0.81; p = 0.03) and maintenance (OR = 0.87; p = 0.03) of active transport to school. Low SES was associated with children's switch to active transport to school compared to maintenance of active transport (OR = 3.67; p = 0.07). For transport to leisure time destinations, other factors such as parental perceived neighborhood safety from traffic and crime (OR = 2.78; p = 0.004), a positive social norm (OR = 1.49; p = 0.08), positive attitudes (OR = 1.39; p = 0.08) (i.e. more benefits, less barriers) towards their children's physical activity and poor walking/cycling facilities in the neighborhood (OR = 0.70; p = 0.06) were associated with children's maintenance of active transport to leisure time destinations compared to a switch to or maintenance of passive transport. This longitudinal study can give directions for interventions promoting children's active transport during the transition to secondary school. It is necessary to promote different possibilities at primary school for children to use active transport when going to secondary school. Walking/cycling a part of the home-school trip can be a possible solution for children who will be living at non-feasible distances from secondary school. Providing safe

    Older adults discharged from the hospital to skilled home health care (SHHC) are at high risk for experiencing suboptimal transitions. Using the human factors approach of shadowing and contextual inquiry, we studied the workflow for transitioning older adults from the hospital to SHHC. We created a representative diagram of the hospital to SHHC transition workflow, we examined potential workflow variations, we categorized workflow challenges, and we identified artifacts developed to manage variations and challenges. We identified three overarching challenges to optimal care transitions-information access, coordination, and communication/teamwork. Future investigations could test whether redesigning the transition from hospital to SHHC, based on our findings, improves workflow and care quality.

    It has been suggested that obese children have lower cognitive function, demonstrate poorer physical performance and are more susceptible to social-emotional problems. To describe associations between human physical growth, cognitive development, physical fitness and social-emotional characteristics of obese and non-obese children and to verify the predictors of intellectual coefficient by socioeconomic status (SES). A sample of 107 non-obese (N-Ob) children [-1 z-score body mass index (BMI) ≤1 z-score] and 108 obese (Ob) children [2 z-score ≤BMI ≤5 z-score] from a larger cohort was evaluated. Intellectual coefficient (IQ), social-emotional wellbeing (SEW), 6-minute walk test (6MWT) and SES (mid-low, low and very low) were assessed. Ob children were taller, heavier and present more height for age and BMI than N-Ob children (p < 0.001). A significant correlation between IQ and SEW (r = 0.14), 6MWT and BMI z-score (r = -0.18) and 6MWT and SEW (r = 0.15) was found. Multiple regression analysis revealed that BMI z-score had a negative impact on IQ in the mid-low SES sub-group and that SEW had a positive effect on IQ in the very-low SES sub-group. In Chilean pre-school children from low-income families cognitive ability varied according to SES.

    After introductory remarks concerning the energy crisis in general, Mr. Reardon treated the following subjects specifically: the nuclear power plant initiative; present and projected demand for electrical power in California; factors influencing demand for electricity; present and projected sources for electrical energy generation; an economic comparison of nuclear, coal, and oil; and the near-, mid-, and long-term economic effects of passage of the nuclear initiative. Summarizing, in a concluding chapter, Mr. Reardon stated that passage of the initiative would cost Californians over the next twenty years about $40 billion. The development of alternative energy sources would require massive expenditures, but the development is more constrained by lack of technology than by dollars. He listed other impacts of concern to Californians, assuming passage of the initiative as: (1) environmental effects of further increased use of oil and coal; (2) increased dependence upon uncertain foreign oil suppliers; (3) accelerated depletion of domestic petroleum resources; (4) slowdown in the substitution of electricity for oil and natural gas; (5) cutback on plans for construction of mass transit and water pollution control facilities; (6) restrictions in economic growth; (7) inability of utilities to meet capital demands for replacement capacity; (8) increased unemployment resulting from relocation of industry; and (9) fiscal hardships on lower- and fixed-income citizens

    Modern travertines, carbonate deposits in Ca-rich hydrothermal water with high pCO2, often display a changing environment along the water path, with corresponding variability in the microbial communities. We investigated a travertine-bearing hot spring at the Blue Pool in northern Sumatra, Indonesia. The thermal water of 62 °C with high H2S (200 μM) and pCO2 ( 1 atm) developed a travertine mound 70 m wide. The concentrations of the gas components H2S and CO2, decrease immediately after the water is discharged, while the dissolved oxygen, pH, and aragonite saturation increase in the downstream direction. Responding to the geochemical gradient in the water, the surface biofilms change color from white to pink, light-green, dark-green, and brown as the water flows from the vent; this corresponds to microbial communities characterized by chemolithoautotrophs (Halothiobacillaceae), purple sulfur bacteria (Chromatiaceae), Anaerolineaceae, and co-occurrence of green non-sulfur bacteria (Chloroflexales)-Cyanobacteria, and green sulfur bacteria (Chlorobiales), respectively. In an environment with a certain level of H2S (> 1 μM), sulfur digestion and anoxygenic photosynthesis can be more profitable than oxygenic photosynthesis by Cyanobacteria. The precipitated carbonate mineral consists of aragonite and calcite, with the proportion of aragonite increasing downstream due to the larger Mg2 +/Ca2 + ratio in the water or the development of thicker biofilm. Where the biofilm is well developed, the aragonite travertines often exhibit laminated structures that were likely associated with the daily metabolism of these bacteria. The microbiological and sedimentological features at the Blue Pool may be the modern analogs of geomicrobiological products in the early Earth. Biofilm of anoxygenic photosynthetic bacteria had the potential to form ancient stromatolites that existed before the appearance of cyanobacteria.

    Inpatient psychiatric readmissions are often used as an indicator of the quality of care and their reduction is in line with international recommendations for mental health care. Research on variations in inpatient readmission rates among mental health care providers is therefore of key importance as these variations can impact equity, quality and efficiency of care when they do not result from differences in patients' needs. Our objectives were first to describe variations in inpatient readmission rates between public mental health care providers in France on a nationwide scale, and second, to identify their association with patient, health care providers and environment characteristics. We carried out a study for the year 2012 using data from ten administrative national databases. 30-day readmissions in inpatient care were identified in the French national psychiatric discharge database. Variations were described numerically and graphically between French psychiatric sectors and factors associated with these variations were identified by carrying out a multi-level logistic regression accounting for the hierarchical structure of the data. Significant practice variations in 30-day inpatient readmission rates were observed with a coefficient of variation above 50%. While a majority of those variations was related to differences within sectors, individual patient characteristics explained a lower part of the variations resulting from differences between sectors than the characteristics of sectors and of their environment. In particular, an increase in the mortality rate and in the acute admission rate for somatic disorders in sectors' catchment area was associated with a decrease in the probability of 30-day readmission. Similarly, an increase in the number of psychiatric inpatient beds in private for-profit hospitals per 1,000 inhabitants in sectors' catchment area was associated with a decrease in this probability, which also varied with overall sectors' case

    The use of food as a reward for good student behavior or academic performance is discouraged by many national organizations, yet this practice continues to occur in schools. Our multiyear cross-sectional study examined the use of food as a reward in elementary schools and evaluated the association between district policies and school practices. School data were gathered during the 2007-2008, 2008-2009, and 2009-2010 school years via mail-back surveys (N=2,069) from respondents at nationally representative samples of US public elementary schools (1,525 unique schools, 544 of which also participated for a second year). During every year, the corresponding district policy for each school was gathered and coded for provisions pertaining to the use of food as a reward. School practices did not change over time and as of the 2009-2010 school year, respondents in 42.1% and 40.7% of schools, respectively, indicated that food was not used as a reward for academic performance or for good student behavior. In multivariate logistic regression analyses controlling for school characteristics and year, having a district policy that prohibited the use of food as a reward was significantly associated with school respondents reporting that food was not used as a reward for academic performance (Preward than were respondents in the South and Northeast. As of 2009-2010, only 11.9% of the districts in our study prohibited the use of food as a reward. Strengthening district policies may reduce the use of food rewards in elementary schools.

    A quantitative risk assessment of mycotoxins due to the consumption of chilli (Capsicum annum L.) and black pepper (Piper nigrum L.) was performed in Sri Lanka. A food frequency questionnaire was administered in order to collect the data on consumption of spices by households in the Northern and Southern region (n = 249). The mean chilli consumption in the North was significantly higher (p spices were estimated. Margin of exposure estimations at the mean exposure to AFB1 were remarkably lower due to chilli (45-78) than for pepper (2315–10,857). Moreover, the hepato cellular carcinoma (HCC) risk associated with the mean AFB1 exposure through chilli at the lower bound was 0.046 and 0.028 HCC cases/year/100,000 based on the North and South consumption, respectively. AFB1 exposure via chilli should be considered as a great public health concern in Sri Lanka due to both high mycotoxin concentration and high consumption.

    Attention-Deficit/Hyperactivity Disorder (ADHD) has a significant impact on child and adolescent development, especially in relation to school functioning and academic outcomes. Despite the transition to high school being a potentially critical period for children with ADHD, most research in this period has focused on academic outcomes. This study aims to extend previous research by describing academic, school engagement, behaviour and social-emotional outcomes for young people with ADHD in the first and third years of high school and to identify risk and protective factors predictive of differing outcomes across these four domains. The Moving Up study is a longitudinal, prospective cohort study of children with ADHD as they transition and adjust to high school (age 12-15 years). Data are collected through direct assessment and child, parent and teacher surveys. The primary outcome is academic achievement, obtained by linking to standardised test results. Secondary outcomes include measures
