    From 1997 to 2000, Philip Morris implemented Project Sunrise. This paper discusses the impact of this project on national and Philip Morris's cigarette unit sales, public opinion about smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use. A qualitative archival content analysis of Project Sunrise from 1997 to 2000, and a descriptive statistical analysis of cigarette unit sales and operating profits, acceptability of smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use from 1996 to 2006. Qualitative data sources related to Project Sunrise found on WebCat, Pubmed.com, LexisNexis Academic and Philip Morris's website, and archived tobacco industry documents were analysed using NVivo Version 9.0. A descriptive statistical analysis of cigarette unit sales, public opinion about smoking and secondhand tobacco smoke, and national prevalence trends for tobacco use was undertaken. Project Sunrise was a high-level strategic corporate plan to maintain profits that included four possible scenarios resulting in seven interwoven strategies. However, national prevalence rates for tobacco use declined, sales of national and Philip Morris cigarettes declined, operating profits remained at substantially lower levels after 2000 from 2001 to 2006, and a large majority of Americans agreed that there were significant health dangers associated with smoking and secondhand tobacco smoke. The impact of Project Sunrise, including countering the anti-tobacco movement, was less than successful in the USA. Copyright © 2012 The Royal Society for Public Health. Published by Elsevier Ltd.

    The Sun Radio Interferometer Space Experiment (SunRISE) is a NASA Heliophysics Explorer Mission of Opportunity currently in Phase A. SunRISE is a constellation of spacecraft flying in a 10-km diameter formation and operating as the first imaging radio interferometer in space. The purpose of SunRISE is to reveal critical aspects of solar energetic particle (SEP) acceleration at coronal mass ejections (CMEs) and transport into space by making the first spatially resolved observations of coherent Type II and III radio bursts produced by electrons accelerated at CMEs or released from flares. SunRISE will focus on solar Decametric-Hectometric (DH, 0.1 space before major SEP events, but cannot be seen on Earth due to ionospheric absorption. This talk will describe SunRISE objectives and implementation. Presented on behalf of the entire SunRISE team.

  8. What Time Is Sunrise? Revisiting the Refraction Component of Sunrise/set Prediction Models

    Science.gov (United States)

    Wilson, Teresa; Bartlett, Jennifer L.; Hilton, James Lindsay

    2017-01-01

    Algorithms that predict sunrise and sunset times currently have an error of one to four minutes at mid-latitudes (0° - 55° N/S) due to limitations in the atmospheric models they incorporate. At higher latitudes, slight changes in refraction can cause significant discrepancies, even including difficulties determining when the Sun appears to rise or set. While different components of refraction are known, how they affect predictions of sunrise/set has not yet been quantified. A better understanding of the contributions from temperature profile, pressure, humidity, and aerosols could significantly improve the standard prediction. We present a sunrise/set calculator that interchanges the refraction component by varying the refraction model. We then compare these predictions with data sets of observed rise/set times to create a better model. Sunrise/set times and meteorological data from multiple locations will be necessary for a thorough investigation of the problem. While there are a few data sets available, we will also begin collecting this data using smartphones as part of a citizen science project. The mobile application for this project will be available in the Google Play store. Data analysis will lead to more complete models that will provide more accurate rise/set times for the benefit of astronomers, navigators, and outdoorsmen everywhere.

    2017-01-01

    Smartphones, with their ever increasing capabilities, are becoming quite instrumental for data acquisition in a number of fields. Understanding refraction and how it affects what we see on the horizon is no exception. Current algorithms that predict sunrise and sunset times have an error of one to four minutes at mid-latitudes (0° - 55° N/S) due to limitations in the atmospheric models they incorporate. At higher latitudes, slight changes in refraction can cause significant discrepancies, even including difficulties determining when the Sun appears to rise or set. A thorough investigation of the problem requires a substantial data set of observed rise/set times and corresponding meteorological data from around the world, which is currently lacking. We have developed a mobile application so that this data can be taken using smartphones as part of a citizen science project. The app allows the viewer to submit a video of sunrise/set and attaches geographic location along with meteorological data taken from a local weather station. The project will help increase scientific awareness in the public by allowing members of the community to participate in the data-taking process, and give them a greater awareness of the scientific significance of phenomenon they witness every day. The data from the observations will lead to more complete rise/set models that will provide more accurate times to the benefit of astronomers, navigators, and outdoorsmen. The app will be available on the Google Play Store.

    In the SUNRISE-project, the unemployment benefit office refers long-term unemployed clients (25-49 years old) to medical and psychological specialists of an addiction clinic, if substance-related problems are suspected as an obstacle for job placement. The present study aims at characterizing these clients with respect to educational qualifications, vocational training, diagnosed addictive disorders, and other mental disorders. Of special interest is the temporal sequence of unemployment and addictive disorders. Officials referred clients to medical examination if substance abuse was suspected. The examination was based on Europ-ASI, diagnosis of mental disorders based on SCID-I and SCID-II. In 87 out of the first 100 examined persons, an addictive disorder was diagnosed, most frequently alcohol-related disorders, and often multiple addictive disorders. These 87 clients were on average 40 years old (SD 8.5), and mostly male (73 out of 87 clients). About one-third had very low school qualification, and 55.2% had not completed vocational training. An additional psychiatric diagnosis was made in 51.7%. Addictive disorders had commenced during adolescence or early adulthood in most cases. The longest duration of continuous employment was 3 years (median). In only a few cases (7.4%), the current period of unemployment had started before regular substance use. Many long-term unemployed clients examined here showed deficits in schooling and vocational training, early onset of regular substance use, and additional mental disorders. In most cases, the addictive disorder did not emerge as a consequence of unemployment, but had existed before. Programs combining the efforts of unemployment benefit offices and the healthcare system are needed for these clients to help them gain access to the regular job market. © Georg Thieme Verlag KG Stuttgart · New York.

  12. Comparing the Effectiveness of Online Sunrise/Sunset Calculators

    The USNO is responsible for providing information through its website on various types of natural phenomena, including times of sunrise and sunset for any given day and location. Alternative websites were explored to see what options are available in case the USNO can no longer support this on-line tool in the future. Websites with sunrise/sunset calculators were examined to see what algorithm they cited, if any. A large percentage of the websites took their calculations from three main sources (USNO, Meeus, and Schlyter). For ease of comparison, one website with an Application Programming Interface (API) for each algorithm was used to generate sunrise/sunset times for 2 dates per year for 24 years at latitudes from the equator to each pole along the prime meridian. Additionally, dates on which only one phenomenon was expected (first and last day of polar day and night) were tested to examine how each algorithm would perform for these extreme edge cases. At mid-latitudes, all of the algorithms agreed within 1 minute of each other but their predictions began to diverge as they approached the poles. Close to the poles, all three differed by more than a minute. While the algorithms diverged well before reaching the poles, Schlyter did so at much lower latitudes compared to the other two. In the edge cases, Schlyter and Meeus did not correctly document the missing sunrise/sunsets. Until a set of arctic or antarctic observations of sunrise and sunset times can be analyzed, we cannot ascertain which algorithm is the most accurate. However, the USNO algorithm handled cases of continuous day and night better than the others. There currently seems to be no better alternative to provide robust sunrise/set times than the USNO Complete Sun and Moon Data for One Day (http://aa.usno.navy.mil/data/docs/RS_OneDay.php).

  14. The two-loop sunrise integral and elliptic polylogarithms

    2016-07-01

    In this talk, we present a solution for the two-loop sunrise integral with arbitrary masses around two and four space-time dimensions in terms of a generalised elliptic version of the multiple polylogarithms. Furthermore we investigate the elliptic polylogarithms appearing in higher orders in the dimensional regularisation ε of the two-dimensional equal mass solution. Around two space-time dimensions the solution consists of a sum of three elliptic dilogarithms where the arguments have a nice geometric interpretation as intersection points of the integration region and an elliptic curve associated to the sunrise integral. Around four space-time dimensions the sunrise integral can be expressed with the ε{sup 0}- and ε{sup 1}-solution around two dimensions, mass derivatives thereof and simpler terms. Considering higher orders of the two-dimensional equal mass solution we find certain generalisations of the elliptic polylogarithms appearing in the ε{sup 0}- and ε{sup 1}-solutions around two and four space-time dimensions. We show that these higher order-solutions can be found by iterative integration within this class of functions.

    We present an update on the Sun Radio Interferometer Space Experiment (SunRISE) mission concept, which was selected for a Step 2 study as part of the Small Explorer (SMEX) Mission of Opportunity (MoO) call. SunRISE is space-based sparse array, composed of six 6U CubeSats, designed to localize the radio emission associated with coronal mass ejections (CMEs) from the Sun. Radio emission from CMEs is a direct tracer of the particle acceleration in the inner heliosphere and potential magnetic connections from the lower solar corona to the larger heliosphere. Furthermore, CME radio emission is quite strong such that only a relatively small number of antennas is required, and a small mission would make a fundamental advancement. Indeed, the state-of-the-art for tracking CME radio emission is defined by single antennas (Wind/WAVES, Stereo/SWAVES) in which the tracking is accomplished by assuming a frequency-to-density mapping. This type of Heliophysics mission would be inherently cost prohibitive in a traditional spacecraft paradigm. However, the use of CubeSats, accompanied by the miniaturization of subsystem components, enables the development of this concept at lower cost than ever before. We present the most recent updates on this mission concept, starting from the concept's performance as compared to the required science and driving technical requirements. We then focus on the SunRISE mission concept of operations, which consists of six 6U CubeSats placed in a GEO graveyard orbit for 6 months to achieve the aforementioned science goals. The spacecraft fly in a passive formation, which allows them to form an interferometer while minimizing the impact on operations complexity. We also present details of the engineering design and the key trades being performed as part of the Step 2 concept study.

  16. Towards Using Smartphones to Refine Sunrise and Sunset Time Models

    Science.gov (United States)

    Wilson, Teresa; Bartlett, Jennifer L.

    2015-01-01

    Current atmospheric models used to predict the times of sunrise and sunset have a minimum error of about one minute. Particularly at higher latitudes, slight changes in refraction may result in significant discrepancies, such as causing the Sun to appear to set several minutes prematurely or remain continuously above the horizon for an unexpectedly long time. Atmospheric models could be better constrained by a substantial collection of observed sunset times with associated meteorological data such temperature, pressure and height of observer. We report on the development of a project recording the necessary data with a few smartphones that will then be the groundwork of a citizen science project.

    Magneto-static models may overcome some of the issues facing force-free magnetic field extrapolations. So far they have seen limited use and have faced problems when applied to quiet-Sun data. Here we present a first application to an active region. We use solar vector magnetic field measurements gathered by the IMaX polarimeter during the flight of the Sunrise balloon-borne solar observatory in 2013 June as boundary conditions for a magneto-static model of the higher solar atmosphere above an active region. The IMaX data are embedded in active region vector magnetograms observed with SDO /HMI. This work continues our magneto-static extrapolation approach, which was applied earlier to a quiet-Sun region observed with Sunrise I. In an active region the signal-to-noise-ratio in the measured Stokes parameters is considerably higher than in the quiet-Sun and consequently the IMaX measurements of the horizontal photospheric magnetic field allow us to specify the free parameters of the model in a special class of linear magneto-static equilibria. The high spatial resolution of IMaX (110–130 km, pixel size 40 km) enables us to model the non-force-free layer between the photosphere and the mid-chromosphere vertically by about 50 grid points. In our approach we can incorporate some aspects of the mixed beta layer of photosphere and chromosphere, e.g., taking a finite Lorentz force into account, which was not possible with lower-resolution photospheric measurements in the past. The linear model does not, however, permit us to model intrinsic nonlinear structures like strongly localized electric currents.

    Radio emission from coronal mass ejections (CMEs) is a direct tracer of particle acceleration in the inner heliosphere and potential magnetic connections from the lower solar corona to the larger heliosphere. Energized electrons excite Langmuir waves, which then convert into intense radio emission at the local plasma frequency, with the most intense acceleration thought to occur within 20 R_S. The radio emission from CMEs is quite strong such that only a relatively small number of antennas is required to detect and map it, but many aspects of this particle acceleration and transport remain poorly constrained. Ground-based arrays would be quite capable of tracking the radio emission associated with CMEs, but absorption by the Earth's ionosphere limits the frequency coverage of ground-based arrays (nu > 15 MHz), which in turn limits the range of solar distances over which they can track the radio emission (concept: A constellation of small spacecraft in a geostationary graveyard orbit designed to localize and track radio emissions in the inner heliosphere. Each spacecraft would carry a receiving system for observations below 25 MHz, and SunRISE would produce the first images of CMEs more than a few solar radii from the Sun. Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

  1. Modeling dynamic exchange of gaseous elemental mercury at polar sunrise.

    At polar sunrise, gaseous elemental mercury (GEM) undergoes an exceptional dynamic exchange in the air and at the snow surface during which GEM can be rapidly removed from the atmosphere (the so-called atmospheric mercury depletion events (AMDEs)) as well as re-emitted from the snow within a few hours to days in the Polar Regions. Although high concentrations of total mercury in snow following AMDEs is well documented, there is very little data available on the redox transformation processes of mercury in the snow and the fluxes of mercury at the air/snow interface. Therefore, the net gain of mercury in the Polar Regions as a result of AMDEs is still an open question. We developed a new version of the global mercury model, GRAHM, which includes for the first time bidirectional surface exchange of GEM in Polar Regions in spring and summer by developing schemes for mercury halogen oxidation, deposition, and re-emission. Also for the first time, GOME satellite data-derived boundary layer concentrations of BrO have been used in a global mercury model for representation of halogen mercury chemistry. Comparison of model simulated and measured atmospheric concentrations of GEM at Alert, Canada, for 3 years (2002-2004) shows the model's capability in simulating the rapid cycling of mercury during and after AMDEs. Brooks et al. (1) measured mercury deposition, reemission, and net surface gain fluxes of mercury at Barrow, AK, during an intensive measurement campaign for a 2 week period in spring (March 25 to April 7, 2003). They reported 1.7, 1.0 +/- 0.2, and 0.7 +/- 0.2 microg m(-2) deposition, re-emission, and net surface gain, respectively. Using the optimal configuration of the model, we estimated 1.8 microg m(-2) deposition, 1.0 microg m(-2) re-emission, and 0.8 microg m(-2) net surface gain of mercury for the same time period at Barrow. The estimated net annual accumulation of mercury within the Arctic Circle north of 66.5 degrees is approximately 174 t with +/-7 t of

    Current atmospheric models used to predict the times of sunrise and sunset have an error of one to four minutes at mid-latitudes (0° - 55° N/S). At higher latitudes, slight changes in refraction may cause significant discrepancies, including determining even whether the Sun appears to rise or set. While different components of refraction are known, how they affect predictions of sunrise/set has not yet been quantified. A better understanding of the contributions from temperature profile, pressure, humidity, and aerosols, could significantly improve the standard prediction. Because sunrise/set times and meteorological data from multiple locations will be necessary for a thorough investigation of the problem, we will collect this data using smartphones as part of a citizen science project. This analysis will lead to more complete models that will provide more accurate times for navigators and outdoorsman alike.

    The ionosphere, at lower regions, behaves differently during sunrise and sunset times compared to the others day times. The E layer which is well formed during the day, almost disappears at these times and the effect of solar presence or absence at these altitudes is well evidenced immediately after sunrise or sunset. In the South Atlantic anomaly region, the energetic particle precipitaton complicates the phenomenon comprehension in these times.

    Background The Czech Republic has one of the poorest tobacco control records in Europe. This paper examines transnational tobacco companies' (TTCs') efforts to influence policy there, paying particular attention to excise policies, as high taxes are one of the most effective means of reducing tobacco consumption, and tax structures are an important aspect of TTC competitiveness. Methods and Findings TTC documents dating from 1989 to 2004/5 were retrieved from the Legacy Tobacco Documents Library website, analysed using a socio-historical approach, and triangulated with key informant interviews and secondary data. The documents demonstrate significant industry influence over tobacco control policy. Philip Morris (PM) ignored, overturned, and weakened various attempts to restrict tobacco advertising, promoting voluntary approaches as an alternative to binding legislation. PM and British American Tobacco (BAT) lobbied separately on tobacco tax structures, each seeking to implement the structure that benefitted its own brand portfolio over that of its competitors, and enjoying success in turn. On excise levels, the different companies took a far more collaborative approach, seeking to keep tobacco taxes low and specifically to prevent any large tax increases. Collective lobbying, using a variety of arguments, was successful in delaying the tax increases required via European Union accession. Contrary to industry arguments, data show that cigarettes became more affordable post-accession and that TTCs have taken advantage of low excise duties by raising prices. Interview data suggest that TTCs enjoy high-level political support and continue to actively attempt to influence policy. Conclusion There is clear evidence of past and ongoing TTC influence over tobacco advertising and excise policy. We conclude that this helps explain the country's weak tobacco control record. The findings suggest there is significant scope for tobacco tax increases in the Czech Republic and

  8. The Tobacco Industry and Children's Rights.

    The manufacture, use, and marketing of tobacco present a serious threat to children's right to health. This makes the Convention on the Rights of the Child a potentially powerful tobacco-control tool and the United Nations Children's Fund (UNICEF), which oversees the convention's implementation, a potential leader in tobacco control. UNICEF actively supported tobacco control initiatives in the late 1990s, but since the early 2000s UNICEF's role in tobacco control has been minimal. Using the Truth Tobacco Industry Documents library, an online collection of previously secret tobacco industry documents, we sought to uncover information on the tobacco industry's ties with UNICEF. We found that from 1997 to 2000, when UNICEF was actively promoting tobacco control to support children's rights, the tobacco industry saw children's rights and UNICEF as potentially powerful threats to business that needed to be closely monitored and neutralized. The industry then positioned itself as a partner with UNICEF on youth smoking prevention initiatives as a way to avoid meaningful tobacco control measures that could save children's lives. After UNICEF's corporate engagement guidelines were loosened in 2003, tobacco companies successfully engaged with UNICEF directly and via front groups, including the Eliminating Child Labour in Tobacco Growing Foundation. This was part of an overall tobacco industry strategy to improve its corporate image, infiltrate the United Nations, and weaken global tobacco-control efforts. As part of its mission to protect children's rights, UNICEF should end all partnerships with the tobacco industry and its front groups. Copyright © 2018 by the American Academy of Pediatrics.

    Algorithms that predict sunrise and sunset times currently have an uncertainty of one to four minutes at mid-latitudes (0° - 55° N/S) due to limitations in the atmospheric models they incorporate. At higher latitudes, slight changes in refraction can cause significant discrepancies, including difficulties determining whether the Sun appears to rise or set. While different components of refraction are known, how they affect predictions of sunrise/set has not yet been quantified. A better understanding of the contributions from temperature profile, pressure, humidity, and aerosols could significantly improve the standard prediction.We present a sunrise/set calculator that interchanges the refraction component by varying the refraction model. We, then, compared these predictions with data sets of observed rise/set times taken from Mount Wilson Observatory in California, University of Alberta in Edmonton, Alberta, and onboard the SS James Franco in the Atlantic. A thorough investigation of the problem requires a more substantial data set of observed rise/set times and corresponding meteorological data from around the world.We have developed a mobile application, Sunrise & Sunset Observer, so that anyone can capture this astronomical and meteorological data using their smartphone video recorder as part of a citizen science project. The Android app for this project is available in the Google Play store. Videos can also be submitted through the project website (riseset.phy.mtu.edu). Data analysis will lead to more complete models that will provide higher accuracy rise/set predictions to benefit astronomers, navigators, and outdoorsmen everywhere.

  12. Preliminary Data Pipeline for SunRISE: Assessing the Performance of Space Based Radio Arrays

    The Sun Radio Interferometer Space Experiment (SunRISE) is a NASA Heliophysics Explorer Mission of Opportunity that was recently awarded phase A funding. SunRISE's main science goals are to localize the source of particle acceleration in coronal mass ejections to 1/4th of their width, and trace the path of electron beams along magnetic field lines out to 20 solar radii. These processes generate cascading Type II and III bursts that have ever only been detected in low frequencies with single spacecraft antenna. These bursts emit below the ionospheric cutoff of 10 MHz past 2 solar radii, so a synthetic aperture made from multiple space antennae is needed to pinpoint the origin of these bursts. In this work, we create an end to end simulation of the data processing pipeline of SunRISE, which uses 6 small satellites to do this localization. One of the main inputs of the simulation is a ground truth of what we want the array to image. We idealized this as an elliptical Gaussian offset from the sun, which previous modeling suggests is a good approximation of what SunRISE would see in space. Another input is an orbit file describing the positions of all the spacecraft. The simulated orbit determinations are made with GPS sidelobes and have an error associated with the recovered positions. From there we compute the Fourier coefficients every antenna will see, then apply the correct phase lags and multiply each pair of coefficients to simulate the process of correlation. We compute the projected UVW coordinates and put these along with the correlated visibilities into a CASA MS file. The correlated visibilities are compared to CASA's simulated visibilities at the same UVW coordinates, verifying the accuracy of our method. The visibilities are then subjected to realistic thermal noise, as well as phase noise from uncertainties in the spacecraft position. We employ CASA's CLEAN algorithm to image the data, and CASA's imfit algorithm to estimate the parameters of the imaged

    We consider the scalar integral associated to the 3-loop sunrise graph with a massless line, two massive lines of equal mass M, a fourth line of mass equal to Mx, and the external invariant timelike and equal to the square of the fourth mass. We write the differential equation in x satisfied by the integral, expand it in the continuous dimension d around d=4 and solve the system of the resulting chained differential equations in closed analytic form, expressing the solutions in terms of harmonic polylogarithms. As a byproduct, we give the limiting values of the coefficients of the (d-4) expansion at x=1 and x=0

    We show that configuration space techniques can be used to efficiently calculate the complete Laurent series ε-expansion of sunrise-type diagrams to any loop order in D-dimensional space-time for any external momentum and for arbitrary mass configurations. For negative powers of ε the results are obtained in analytical form. For positive powers of ε including the finite ε 0 contribution the result is obtained numerically in terms of low-dimensional integrals. We present general features of the calculation and provide exemplary results up to five-loop order which are compared to available results in the literature. (orig.)

    We use brand association and symbolic consumption theory to explore how plain cigarette packaging would influence the identities young adults cocreate with tobacco products. Group discussions and in-depth interviews with 86 young adult smokers and nonsmokers investigated how participants perceive tobacco branding and plain cigarette packaging with larger health warnings. We examined the transcript data using thematic analysis and explored how removing tobacco branding and replacing this with larger warnings would affect the symbolic status of tobacco brands and their social connotations. Smokers used tobacco brand imagery to define their social attributes and standing, and their connection with specific groups. Plain cigarette packaging usurped this process by undermining aspirational connotations and exposing tobacco products as toxic. Replacing tobacco branding with larger health warnings diminishes the cachet brand insignia creates, weakens the social benefits brands confer on users, and represents a potentially powerful policy measure.

    Full Text Available Tourist ascents of mountain peaks before sunrise are increasingly popular. Babia Góra (Western Carpathians is a peak on the Polish-Slovak border frequently visited by a great number of tourists at sunrise. The main objective of our research, based on the case study of Babia Gora, was to answer a more general question whether the sunrise can be considered a tourist attraction. The research included the observation and description of every sunrise at summer holiday weekends during 2012 from the peak of Babia Góra as well as the collection of data on the number of tourists and weather conditions. Survey interviews, using questionnaire, with randomly selected hikers present on the peak of Babia Góra at sunrise (269 were conducted. The investigation showed that during summer holiday sunrises there were a maximum of 130 people on the summit of Babia Góra at the same time. Most of the surveyed people (84% agreed that the opportunity to observe the sunrise was one of the pull factors for them. This confirms the hypothesis that sunrise constitutes a tourist attraction.

  19. An improved recommendation algorithm via weakening indirect linkage effect

    We propose an indirect-link-weakened mass diffusion method (IMD), by considering the indirect linkage and the source object heterogeneity effect in the mass diffusion (MD) recommendation method. Experimental results on the MovieLens, Netflix, and RYM datasets show that, the IMD method greatly improves both the recommendation accuracy and diversity, compared with a heterogeneity-weakened MD method (HMD), which only considers the source object heterogeneity. Moreover, the recommendation accuracy of the cold objects is also better elevated in the IMD than the HMD method. It suggests that eliminating the redundancy induced by the indirect linkages could have a prominent effect on the recommendation efficiency in the MD method. (paper)

    2009-08-01

    This article outlines how the tobacco industry has undermined tobacco control efforts in Lebanon since the early 1970s. An analysis of online and on-site tobacco industry documents, reviews of newspapers, policy and other documents, and interviews with key policy makers were conducted. Findings reveal how the weakness of tobacco control legislation in Lebanon has been the product of an effective tobacco industry strategy to weaken the content and scope of regulation, and delay adoption and implementation. The tobacco industry has built and maintained strong alliances that were and are regularly mobilised to effectively oppose regulation. Despite ratification of the World Health Organization Framework Convention on Tobacco Control in 2005, Lebanon's tobacco control track remains weak. Public health professionals and the government should work hard to oppose such tobacco industry tactics.

    Gaseous elemental mercury (Hg0) is a globally distributed air toxin with a long atmospheric residence time. Any process that reduces its atmospheric lifetime increases its potential accumulation in the biosphere. Our data from Barrow, AK, at 71 degrees N show that rapid, photochemically driven...... oxidation of boundary-layer Hg0 after polar sunrise, probably by reactive halogens, creates a rapidly depositing species of oxidized gaseous mercury in the remote Arctic troposphere at concentrations in excess of 900 pg m(-3). This mercury accumulates in the snowpack during polar spring at an accelerated...... rate in a form that is bioavailable to bacteria and is released with snowmelt during the summer emergence of the Arctic ecosystem. Evidence suggests that this is a recent phenomenon that may be occurring throughout the earth's polar regions. Udgivelsesdato: 2002-Mar-15...

  3. Elliptic polylogarithms and iterated integrals on elliptic curves. II. An application to the sunrise integral

    Science.gov (United States)

    Broedel, Johannes; Duhr, Claude; Dulat, Falko; Tancredi, Lorenzo

    2018-06-01

    We introduce a class of iterated integrals that generalize multiple polylogarithms to elliptic curves. These elliptic multiple polylogarithms are closely related to similar functions defined in pure mathematics and string theory. We then focus on the equal-mass and non-equal-mass sunrise integrals, and we develop a formalism that enables us to compute these Feynman integrals in terms of our iterated integrals on elliptic curves. The key idea is to use integration-by-parts identities to identify a set of integral kernels, whose precise form is determined by the branch points of the integral in question. These kernels allow us to express all iterated integrals on an elliptic curve in terms of them. The flexibility of our approach leads us to expect that it will be applicable to a large variety of integrals in high-energy physics.

    This November 13, 1995, photograph of the F-15 Advanced Controls Technology for Integrated Vehicles (ACTIVE) at NASA's Dryden Flight Research Center, Edwards, California, shows the aircraft on a test stand at sunrise. Not shown in this photograph are the aircraft's two new Pratt & Whitney nozzles that can turn up to 20 degrees in any direction. These nozzles give the aircraft thrust control in the pitch (up and down) and yaw (left and right) directions. This will reduce drag and increase fuel economy or range as compared with conventional aerodynamic controls, which increase the retarding forces (drag) acting upon the aircraft. These tests could result in significant performance increases for military and commercial aircraft. The research program is the product of a collaborative effort by NASA, the Air Force's Wright Laboratory, Pratt & Whitney, and McDonnell Douglas Aerospace. The aircraft was originally built as an F-15B (Serial #71-0290).

    2018-01-01

    For this study, samples from different lithologies ("Leitha"-limestone, "Dachstein"-limestone, "Haupt"-dolomite, "Bunt"-sandstone, Grey Berea sandstone, granite, quartzite and basalt) were selected. Samples were dried at 70 °C, respectively 105 °C and were saturated with brine. Mass, porosity, permeability, compressional and shear wave velocity were determined from dry and brine saturated samples at laboratory conditions, based on an individual measurement program. Shear modulus was calculated to find out, if shear weakening exists for the dataset. Shear weakening means that shear modulus of dry samples is higher than of saturated samples, but it is assumed that shear modulus is unaffected by saturation. "Dachstein"-limestone and basalt show shear weakening, quartzite samples show both weakening and hardening. Granite samples are affected by temperature, after drying with 105 °C no change can be observed anymore. "Bunt"-sandstone samples show a change in the shear modulus in a small extent, although they may contain clay minerals. The other lithologies show no effect. Explanations for carbonate samples can be the complicated pore structure, for basalt it could be that weathering creates clay minerals which are known as causes for a change of the shear modulus. Fluid viscosity can also be an important factor.

    Full Text Available PURPOSE: To evaluate the influence of the oblique muscles surgical weakening on the horizontal alignment in the primary position (PP and its efficacy on the correction of the "A" and "V" anisotropies. METHODS: In order to study the influence of bilateral superior oblique muscles (SO weakening on the horizontal alignment in PP, we analyzed the files of 12 patients who underwent only that operation; no other muscle was operated on. We took the opportunity of those 12 patients to analyze the effect of their operation on the correction of "A" incomitance. For evaluating the effect of the inferior oblique muscles (IO weakening on the correction of the "V" pattern, we analyzed retrospectively the files of 67 anisotropic patients who underwent a bilateral SO weakening. In 10 of them, the only operation was the oblique muscles weakening and, in 57 patients, the horizontal recti were also operated on for the horizontal deviations in primary position. These patients were divided into two groups: 50 were esotropic and 17 exotropic. There was not any mixed anisotropy. RESULTS: The mean value of the preoperative "V" incomitance of the 50 esotropic patients was 24.25∆ ± 10.15∆; the mean postoperative correction was 15.56 ∆ ± 8.74∆. The mean correction between the PP and upgaze was 7.52∆ ± 7.47∆ and from the PP to downgaze was 8.56∆ ± 9.21∆. The same values of the 17 exotropic patients was: preoperative 31.88∆ ± 9.4∆; primary position to upgaze was 13.11∆ ± 4.9∆ and primary position to downgaze 14.11∆ ± 12.48∆. The mean preoperative value of the "A" incomitance among the 12 patients who underwent isolated SO weakening was 30.50∆ ± 19.25∆ and the postoperative was of 9,92∆, therefore a mean correction of 22.58∆ ± 17.54∆. Among these ones, in 5 there was no alteration of the deviation in primary position, in 4 there was an exo-effect and in 3 there was an eso-effect. The mean alteration of the deviation in PP was an

  12. Weakened tropical circulation and reduced precipitation in response to geoengineering

    International Nuclear Information System (INIS)

    Ferraro, Angus J; Highwood, Eleanor J; Charlton-Perez, Andrew J

    2014-01-01

    Geoengineering by injection of reflective aerosols into the stratosphere has been proposed as a way to counteract the warming effect of greenhouse gases by reducing the intensity of solar radiation reaching the surface. Here, climate model simulations are used to examine the effect of geoengineering on the tropical overturning circulation. The strength of the circulation is related to the atmospheric static stability and has implications for tropical rainfall. The tropical circulation is projected to weaken under anthropogenic global warming. Geoengineering with stratospheric sulfate aerosol does not mitigate this weakening of the circulation. This response is due to a fast adjustment of the troposphere to radiative heating from the aerosol layer. This effect is not captured when geoengineering is modelled as a reduction in total solar irradiance, suggesting caution is required when interpreting model results from solar dimming experiments as analogues for stratospheric aerosol geoengineering.

    2015-09-01

    Full Text Available The hybrid excitation synchronous motor (HESM, which aim at combining the advantages of permanent magnet motor and wound excitation motor, have the characteristics of low-speed high-torque hill climbing and wide speed range. Firstly, a new kind of HESM is presented in the paper, and its structure and mathematical model are illustrated. Then, based on a space voltage vector control, a novel flux-weakening method for speed adjustment in the high speed region is presented. The unique feature of the proposed control method is that the HESM driving system keeps the q-axis back-EMF components invariable during the flux-weakening operation process. Moreover, a copper loss minimization algorithm is adopted to reduce the copper loss of the HESM in the high speed region. Lastly, the proposed method is validated by the simulation and the experimental results.

  16. Businesses' voluntary pro-health tobacco policies: a review and research agenda.

    Science.gov (United States)

    McDaniel, Patricia A; Malone, Ruth E

    2012-01-01

    Research on the role of businesses in tobacco control has focused primarily on retailers, advertising firms and the hospitality industry, all of which have tended to support tobacco industry interests and resist effective tobacco control policies. However, in several countries, businesses have a history of voluntarily adopting tobacco-related policies that may advance tobacco control objectives. These phenomena have received little research attention. Existing literature on businesses ending tobacco sales, instituting voluntary workplace smoking restrictions and establishing non-smoker only hiring policies was reviewed. A research agenda on voluntary business initiatives would enhance and complement research on mandatory tobacco control policies by identifying new advocacy opportunities; suggesting avenues for strengthening or reinforcing existing policy initiatives; laying the groundwork for new mandatory policies; helping to inform ethical debates about contentious voluntary policies; and contributing to a better understanding of how alliances between the tobacco industry and other businesses might be weakened.

  17. Statistical evolution of quiet-Sun small-scale magnetic features using Sunrise observations

    The evolution of small magnetic features in quiet regions of the Sun provides a unique window for probing solar magneto-convection. Here we analyze small-scale magnetic features in the quiet Sun, using the high resolution, seeing-free observations from the Sunrise balloon borne solar observatory. Our aim is to understand the contribution of different physical processes, such as splitting, merging, emergence and cancellation of magnetic fields to the rearrangement, addition and removal of magnetic flux in the photosphere. We have employed a statistical approach for the analysis and the evolution studies are carried out using a feature-tracking technique. In this paper we provide a detailed description of the feature-tracking algorithm that we have newly developed and we present the results of a statistical study of several physical quantities. The results on the fractions of the flux in the emergence, appearance, splitting, merging, disappearance and cancellation qualitatively agrees with other recent studies. To summarize, the total flux gained in unipolar appearance is an order of magnitude larger than the total flux gained in emergence. On the other hand, the bipolar cancellation contributes nearly an equal amount to the loss of magnetic flux as unipolar disappearance. The total flux lost in cancellation is nearly six to eight times larger than the total flux gained in emergence. One big difference between our study and previous similar studies is that, thanks to the higher spatial resolution of Sunrise, we can track features with fluxes as low as 9 × 1014 Mx. This flux is nearly an order of magnitude lower than the smallest fluxes of the features tracked in the highest resolution previous studies based on Hinode data. The area and flux of the magnetic features follow power-law type distribution, while the lifetimes show either power-law or exponential type distribution depending on the exact definitions used to define various birth and death events. We have

    We have investigated a time series of continuum intensity maps and corresponding Dopplergrams of granulation in a very quiet solar region at the disk center, recorded with the Imaging Magnetograph eXperiment (IMaX) on board the balloon-borne solar observatory SUNRISE. We find that granules frequently show substructure in the form of lanes composed of a leading bright rim and a trailing dark edge, which move together from the boundary of a granule into the granule itself. We find strikingly similar events in synthesized intensity maps from an ab initio numerical simulation of solar surface convection. From cross sections through the computational domain of the simulation, we conclude that these granular lanes are the visible signature of (horizontally oriented) vortex tubes. The characteristic optical appearance of vortex tubes at the solar surface is explained. We propose that the observed vortex tubes may represent only the large-scale end of a hierarchy of vortex tubes existing near the solar surface.

    We characterize waves in small magnetic elements and investigate their propagation in the lower solar atmosphere from observations at high spatial and temporal resolution. We use the wavelet transform to analyze oscillations of both horizontal displacement and intensity in magnetic bright points found in the 300 nm and the Ca ii H 396.8 nm passbands of the filter imager on board the Sunrise balloon-borne solar observatory. Phase differences between the oscillations at the two atmospheric layers corresponding to the two passbands reveal upward propagating waves at high frequencies (up to 30 mHz). Weak signatures of standing as well as downward propagating waves are also obtained. Both compressible and incompressible (kink) waves are found in the small-scale magnetic features. The two types of waves have different, though overlapping, period distributions. Two independent estimates give a height difference of approximately 450 ± 100 km between the two atmospheric layers sampled by the employed spectral bands. This value, together with the determined short travel times of the transverse and longitudinal waves provide us with phase speeds of 29 ± 2 km s −1 and 31 ± 2 km s −1 , respectively. We speculate that these phase speeds may not reflect the true propagation speeds of the waves. Thus, effects such as the refraction of fast longitudinal waves may contribute to an overestimate of the phase speed.

    With the creation of Mount Rainier National Park (MORA) in 1899 came the active management of the park's landscapes and a heavy emphasis on fire suppression. Today, managers at MORA seek to better manage current fire activity; however, this requires an improved understanding of past fire activity on the mountain. In this study high-resolution macroscopic charcoal analysis and pollen analysis of lake sediment records was used to reconstruct the postglacial fire and vegetation history for the Sunrise Ridge area of MORA. Fire activity was lowest during the Late Glacial when vegetation was sparse and climate was cool and dry. Fire activity increased during the early Holocene as the regional climate warmed and dried, and burnable biomass became more abundant. Fire activity continued to increase into the middle Holocene (until ca. 6600 cal yr BP) even as the regional climate became wetter and eventually cooler; the modern-day mesic forest and subalpine meadow landscapes of the park established at this time. Fire activity was generally highest and mean fire return intervals were lowest on Sunrise Ridge during the late Holocene, and are consistent with tree-ring based estimates of fire frequency. The similarity between the Sunrise Ridge and other paleofire records in the Pacific Northwest suggests that broad-scale climatic shifts, such as the retreat of the Cordilleran ice sheet and changes in annual insolation, as well as increased interannual climate variability (i.e., drought) particularly in the middle to late Holocene, were responsible for changes in fire activity during the postglacial period. However, abundant and increasing archaeological evidence from Sunrise Ridge during the middle to late Holocene suggests that humans may have also influenced the landscape at this time. It is likely that fires will continue to increase at MORA as drought becomes a more frequent occurrence in the Pacific Northwest.

  4. Youth access to tobacco.

    To start smoking, young people need a supply of tobacco products. Reducing youth access to tobacco is a new approach to preventing tobacco use that has been a focus of federal, state, and local tobacco control efforts over the past decade. All 50 states ban tobacco sales to minors, but compliance is poor because laws are not enforced. Consequently, young people have little trouble obtaining tobacco products. Commercial sources of tobacco (stores and vending machines) are important for underage smokers, who often purchase their own cigarettes. Underage youths also obtain tobacco from noncommercial sources such as friends, relatives, older adolescents, and adults. Educating retailers about tobacco sales laws has not produced long-term improvement in their compliance. Active enforcement of tobacco sales laws changes retailer behavior, but whether this reduces young people's access to tobacco or their tobacco use is not clear. The effectiveness of new local, state, and federal actions that aim to reduce youth access to tobacco remains to be determined. Can enforcing tobacco sales laws reduce young people's access to tobacco? If so, will this prevent or delay the onset of their tobacco use? How will youths' sources of tobacco change as commercial sources are restricted? What are the social (noncommercial) sources of tobacco for minors and how can youths' access to tobacco from these sources be reduced? What is the impact of the new federal policies aimed at reducing youth access to tobacco? Do new state and local laws that ban youth possession or use of tobacco have a net positive or negative impact on youth attitudes, access to tobacco, or tobacco use? What is the relative effectiveness and cost-effectiveness of efforts to reduce the supply of tobacco compared to those that aim to reduce demand for tobacco? Will either work alone or are both necessary to achieve reductions in youth smoking?

    We present observations of transverse oscillations in slender Ca ii H fibrils (SCFs) in the lower solar chromosphere. We use a 1 hr long time series of high- (spatial and temporal-) resolution seeing-free observations in a 1.1 Å wide passband covering the line core of Ca ii H 3969 Å from the second flight of the Sunrise balloon-borne solar observatory. The entire field of view, spanning the polarity inversion line of an active region close to the solar disk center, is covered with bright, thin, and very dynamic fine structures. Our analysis reveals the prevalence of transverse waves in SCFs with median amplitudes and periods on the order of 2.4 ± 0.8 km s{sup −1} and 83 ± 29 s, respectively (with standard deviations given as uncertainties). We find that the transverse waves often propagate along (parts of) the SCFs with median phase speeds of 9 ± 14 km s{sup −1}. While the propagation is only in one direction along the axis in some of the SCFs, propagating waves in both directions, as well as standing waves are also observed. The transverse oscillations are likely Alfvénic and are thought to be representative of magnetohydrodynamic kink waves. The wave propagation suggests that the rapid high-frequency transverse waves, often produced in the lower photosphere, can penetrate into the chromosphere with an estimated energy flux of ≈15 kW m{sup −2}. Characteristics of these waves differ from those reported for other fibrillar structures, which, however, were observed mainly in the upper solar chromosphere.

    Although fluids are pervasive among tectonic faults, thermo-hydro-mechanical couplings during earthquake slip remain unclear. We report full dynamic records of stick-slip events, performed on saw cut Westerly Granite samples loaded under triaxial conditions at stresses representative of the upper continental crust (σ3' 70 MPa) Three fluid pressure conditions were tested, dry, low , and high pressure (i.e. Pf=0, 1, and 25 MPa). Friction (μ) evolution recorded at 10 MHz sampling frequency showed that, for a single event, μ initially increased from its static pre-stress level, μ0 to a peak value μ p it then abruptly dropped to a minimum dynamic value μd before recovering to its residual value μr, where the fault reloaded elastically. Under dry and low fluid pressure conditions, dynamic friction (μd) was extremely low ( 0.2) and co-seismic slip (δ) was large ( 250 and 200 μm respectively) due to flash heating (FH) and melting of asperities as supported by microstructures. Conversely, at pf=25 MPa, μd was higher ( 0.45), δ was smaller ( 80 μm), and frictional melting was not found. We calculated flash temperatures at asperity contacts including heat buffering by on-fault fluid. Considering the isobaric evolution of water's thermodynamic properties with rising temperature showed that pressurized water controlled fault heating and weakening, through sharp variations of specific heat (cpw) and density (ρw) at water's phase transitions. Injecting the computed flash temperatures into slip-on-a-plane model for thermal pressurization (TP) showed that: (i) if pf was low enough so that frictional heating induced liquid/vapour phase transition, FH operated, allowing very low μd during earthquakes. (ii) Conversely, if pf was high enough that shear heating induced a sharp phase transition directly from liquid to supercritical state, an extraordinary rise in water's specific heat acted as a major energy sink inhibiting FH and limiting TP, allowing higher dynamic fault

    We investigate the thermal expansion behaviors of monolayer graphene and three configurations of graphene with point defects, namely the replacement of one carbon atom with a boron or nitrogen atom, or of two neighboring carbon atoms by boron-nitrogen atoms, based on calculations using first-principles density functional theory. It is found that the thermal contraction of monolayer graphene is significantly decreased by point defects. Moreover, the corresponding temperature for negative linear thermal expansion coefficient with the maximum absolute value is reduced. The cause is determined to be point defects that enhance the mechanical strength of graphene and then reduce the amplitude and phonon frequency of the out-of-plane acoustic vibration mode. Such defect weakening of graphene thermal contraction will be useful in nanotechnology to diminish the mismatching or strain between the graphene and its substrate.

    The commonly known technology of field weakening for permanent-magnet (PM) motors is achieved by controlling the direct-axis current component through an inverter, without using mechanical variation of the air gap, a new machine approach for field weakening of PM machines by direct control of air-gap fluxes is introduced. The demagnetization situation due to field weakening is not an issue with this new method. In fact, the PMs are strengthened at field weakening. The field-weakening ratio can reach 1O:1 or higher. This technology is particularly useful for the PM generators and electric vehicle drives.

    Bright points (BPs) in the solar photosphere are thought to be the radiative signatures (small-scale brightness enhancements) of magnetic elements described by slender flux tubes or sheets located in the darker intergranular lanes in the solar photosphere. They contribute to the ultraviolet (UV) flux variations over the solar cycle and hence may play a role in influencing the Earth's climate. Here we aim to obtain a better insight into their properties by combining high-resolution UV and spectro-polarimetric observations of BPs by the Sunrise Observatory with 3D compressible radiation magnetohydrodynamical (MHD) simulations. To this end, full spectral line syntheses are performed with the MHD data and a careful degradation is applied to take into account all relevant instrumental effects of the observations. In a first step it is demonstrated that the selected MHD simulations reproduce the measured distributions of intensity at multiple wavelengths, line-of-sight velocity, spectral line width, and polarization degree rather well. The simulated line width also displays the correct mean, but a scatter that is too small. In the second step, the properties of observed BPs are compared with synthetic ones. Again, these are found to match relatively well, except that the observations display a tail of large BPs with strong polarization signals (most likely network elements) not found in the simulations, possibly due to the small size of the simulation box. The higher spatial resolution of the simulations has a significant effect, leading to smaller and more numerous BPs. The observation that most BPs are weakly polarized is explained mainly by the spatial degradation, the stray light contamination, and the temperature sensitivity of the Fe i line at 5250.2 Å. Finally, given that the MHD simulations are highly consistent with the observations, we used the simulations to explore the properties of BPs further. The Stokes V asymmetries increase with the distance to the

    A new class of identities for Feynman graph amplitudes, dubbed Schouten identities, valid at fixed integer value of the dimension d is proposed. The identities are then used in the case of the two-loop sunrise graph with arbitrary masses for recovering the second-order differential equation for the scalar amplitude in d=2 dimensions, as well as a chained set of equations for all the coefficients of the expansions in (d−2). The shift from d≈2 to d≈4 dimensions is then discussed

    Future changes in the North American monsoon, a circulation system that brings abundant summer rains to vast areas of the North American Southwest, could have significant consequences for regional water resources. How this monsoon will change with increasing greenhouse gases, however, remains unclear, not least because coarse horizontal resolution and systematic sea-surface temperature biases limit the reliability of its numerical model simulations. Here we investigate the monsoon response to increased atmospheric carbon dioxide (CO2) concentrations using a 50-km-resolution global climate model which features a realistic representation of the monsoon climatology and its synoptic-scale variability. It is found that the monsoon response to CO2 doubling is sensitive to sea-surface temperature biases. When minimizing these biases, the model projects a robust reduction in monsoonal precipitation over the southwestern United States, contrasting with previous multi-model assessments. Most of this precipitation decline can be attributed to increased atmospheric stability, and hence weakened convection, caused by uniform sea-surface warming. These results suggest improved adaptation measures, particularly water resource planning, will be required to cope with projected reductions in monsoon rainfall in the American Southwest.

  16. Slip weakening, strain and short-termpreseismic disturbances

    Directory of Open Access Journals (Sweden)

    V. A. Morgounov

    2004-06-01

    Full Text Available The problem of short-term earthquake precursors is discussed. In contrast to the increasing number of reports on short-lived precursors of various types, direct strain measurements cannot detect clearly expressed preseismic anomalies, as follows from the aseismic nucleation mechanism. Based on previously published data and the assumption that the attenuation of the stress-strain field is proportional to r- 3, a possible scenario of the final stage of earthquake nucleation process is proposed on the basis of the slip weakening mechanism in the source and the associated mosaic pattern of precursors on the Earth?s surface. The formulas for estimating the maximum distance of precursor detection and minimum duration of the final stage of inelastic deformation preceding brittle failure of rocks are derived. The data of electromagnetic precursors are interpreted in terms of a skin-layer model. A considerable increase in strain rates at the final stage of the earthquake nucleation provides an opportunity to explain teleseismic effects before strong earthquakes in terms of normalized epicenter distance. The modeling results are compared with in situ observations.

  17. Macroalgal spore dysfunction: ocean acidification delays and weakens adhesion.

    Early life stages of marine organisms are predicted to be vulnerable to ocean acidification. For macroalgae, reproduction and population persistence rely on spores to settle, adhere and continue the algal life cycle, yet the effect of ocean acidification on this critical life stage has been largely overlooked. We explicitly tested the biomechanical impact of reduced pH on early spore adhesion. We developed a shear flume to examine the effect of reduced pH on spore attachment time and strength in two intertidal rhodophyte macroalgae, one calcified (Corallina vancouveriensis) and one noncalcified (Polyostea robusta). Reduced pH delayed spore attachment of both species by 40%-52% and weakened attachment strength in C. vancouveriensis, causing spores to dislodge at lower flow-induced shear forces, but had no effect on the attachment strength of P. robusta. Results are consistent with our prediction that reduced pH disrupts proper curing and gel formation of spore adhesives (anionic polysaccharides and glycoproteins) via protonation and cation displacement, although experimental verification is needed. Our results demonstrate that ocean acidification negatively, and differentially, impacts spore adhesion in two macroalgae. If results hold in field conditions, reduced ocean pH has the potential to impact macroalgal communities via spore dysfunction, regardless of the physiological tolerance of mature thalli. © 2017 Phycological Society of America.

    The evolution of the physical parameters of magnetic bright points (MBPs) located in the quiet Sun (mainly in the interwork) during their lifetime is studied. First, we concentrate on the detailed description of the magnetic field evolution of three MBPs. This reveals that individual features follow different, generally complex, and rather dynamic scenarios of evolution. Next, we apply statistical methods on roughly 200 observed MBP evolutionary tracks. MBPs are found to be formed by the strengthening of an equipartition field patch, which initially exhibits a moderate downflow. During the evolution, strong downdrafts with an average velocity of 2.4 km s{sup –1} set in. These flows, taken together with the concurrent strengthening of the field, suggest that we are witnessing the occurrence of convective collapses in these features, although only 30% of them reach kG field strengths. This fraction might turn out to be larger when the new 4 m class solar telescopes are operational as observations of MBPs with current state of the art instrumentation could still be suffering from resolution limitations. Finally, when the bright point disappears (although the magnetic field often continues to exist) the magnetic field strength has dropped to the equipartition level and is generally somewhat weaker than at the beginning of the MBP's evolution. Also, only relatively weak downflows are found on average at this stage of the evolution. Only 16% of the features display upflows at the time that the field weakens, or the MBP disappears. This speaks either for a very fast evolving dynamic process at the end of the lifetime, which could not be temporally resolved, or against strong upflows as the cause of the weakening of the field of these magnetic elements, as has been proposed based on simulation results. It is noteworthy that in about 10% of the cases, we observe in the vicinity of the downflows small-scale strong (exceeding 2 km s{sup –1}) intergranular upflows

    Full Text Available Smoking, especially cigarette smoking, is the most common form of tobacco consumption world-wide. It is generally accepted that smoking carries health risks for smokers. The combustion and pyrolysis products of tobacco generated during smoking are considered to be responsible for the harmful effects. Smokeless tobacco, another wide-spread form of tobacco use, is not subjected to burning and produces no combustion or pyrolysis products. Therefore, there is an increasingly intense debate about the potential role of smokeless tobacco in reducing the harm of tobacco use.

    To investigate the longitudinal impact of smoking cessation and relapse on the exercise habits of apparently healthy Japanese men, 750 subjects presenting for a checkup at a metropolitan health center were surveyed annually for 7 years. Exercise was dichotomously classified as none or any. Subjects were grouped in two categories: 98 smokers who ceased smoking during the second year of the study, matched with 196 continuing smokers and 196 men who had never smoked; and 52 relapsed smokers (including 2 new smokers) who did not smoke at baseline or at Year 1 but smoked from Year 2 to final follow-up, matched with 104 continuing smokers and 104 never-smokers. Based on self-reported responses to questionnaires, exercise was consistently less prevalent among smokers who did not quit than among never-smokers throughout the study. Habitual exercise in subjects who had quit smoking increased during the follow-up (any exercise: 42.9% at baseline increased to 51% at final follow-up, p for longitudinal trend = .115). Habitual exercise in matched never-smokers did not change during the study and decreased significantly among persistent smokers (p = .025). Habitual exercise in relapsed smokers decreased during the follow-up (any exercise: 50.0% at baseline declined to 32.7% at final follow-up, p = .007), but habitual exercise in matched persistent smokers and never-smokers did not change. We conclude that smoking and sedentary lifestyle coexist continuously, that smoking cessation is associated with increased habitual exercise among healthy men, and that relapse is associated with reduced habitual exercise, suggesting that cigarette smoking weakens exercise habits.

  2. Black carbon reduction will weaken the aerosol net cooling effect

    2014-12-01

    Black carbon (BC), a distinct type of carbonaceous material formed from the incomplete combustion of fossil and biomass based fuels under certain conditions, can interact with solar radiation and clouds through its strong light-absorption ability, thereby warming the Earth's climate system. Some studies have even suggested that global warming could be slowed down in a short term by eliminating BC emission due to its short lifetime. In this study, we estimate the influence of removing some sources of BC and other co-emitted species on the aerosol radiative effect by using an aerosol-climate coupled model BCC_AGCM2.0.1_CUACE/Aero, in combination with the aerosol emissions from the Representative Concentration Pathways (RCPs) scenarios. We find that the global annual mean aerosol net cooling effect at the top of the atmosphere (TOA) will be enhanced by 0.12 W m-2 compared with present-day conditions if the BC emission is reduced exclusively to the level projected for 2100 based on the RCP2.6 scenario. This will be beneficial for the mitigation of global warming. However, the global annual mean aerosol net cooling effect at the TOA will be weakened by 1.7-2.0 W m-2 relative to present-day conditions if emissions of BC and co-emitted sulfur dioxide and organic carbon are simultaneously reduced as the most close conditions to the actual situation to the level projected for 2100 in different ways based on the RCP2.6, RCP4.5, and RCP8.5 scenarios. Because there are no effective ways to remove the BC exclusively without influencing the other co-emitted components, our results therefore indicate that a reduction in BC emission can lead to an unexpected warming on the Earth's climate system in the future.

    The composite Sunrise Butte pluton, in the central part of the Blue Mountains Province, northeastern Oregon, preserves a record of subduction-related magmatism, arc-arc collision, crustal thickening, and deep-crustal anatexis. The earliest phase of the pluton (Desolation Creek unit) was generated in a subduction zone environment, as the oceanic lithosphere between the Wallowa and Olds Ferry island arcs was consumed. Zircons from this unit yielded a 206Pb/238U age of 160.2 ± 2.1 Ma. A magmatic lull ensued during arc-arc collision, after which partial melting at the base of the thickened Wallowa arc crust produced siliceous magma that was emplaced into metasedimentary rocks and serpentinite of the overthrust forearc complex. This magma crystallized to form the bulk of the Sunrise Butte composite pluton (the Sunrise Butte unit; 145.8 ± 2.2 Ma). The heat necessary for crustal anatexis was supplied by coeval mantle-derived magma (the Onion Gulch unit; 147.9 ± 1.8 Ma).The lull in magmatic activity between 160 and 148 Ma encompasses the timing of arc-arc collision (159–154 Ma), and it is similar to those lulls observed in adjacent areas of the Blue Mountains Province related to the same shortening event. Previous researchers have proposed a tectonic link between the Blue Mountains Province and the Klamath Mountains and northern Sierra Nevada Provinces farther to the south; however, timing of Late Jurassic deformation in the Blue Mountains Province predates the timing of the so-called Nevadan orogeny in the Klamath Mountains. In both the Blue Mountains Province and Klamath Mountains, the onset of deep-crustal partial melting initiated at ca. 148 Ma, suggesting a possible geodynamic link. One possibility is that the Late Jurassic shortening event recorded in the Blue Mountains Province may be a northerly extension of the Nevadan orogeny. Differences in the timing of these events in the Blue Mountains Province and the Klamath–Sierra Nevada Provinces suggest that

  8. Distributions of Polycyclic Aromatic Hydrocarbons, Aromatic Ketones, Carboxylic Acids, and Trace Metals in Arctic Aerosols: Long-Range Atmospheric Transport, Photochemical Degradation/Production at Polar Sunrise.

    The distributions, correlations, and source apportionment of aromatic acids, aromatic ketones, polycyclic aromatic hydrocarbons (PAHs), and trace metals were studied in Canadian high Arctic aerosols. Nineteen PAHs including minor sulfur-containing heterocyclic PAH (dibenzothiophene) and major 6 carcinogenic PAHs were detected with a high proportion of fluoranthene followed by benzo[k]fluoranthene, pyrene, and chrysene. However, in the sunlit period of spring, their concentrations significantly declined likely due to photochemical decomposition. During the polar sunrise from mid-March to mid-April, benzo[a]pyrene to benzo[e]pyrene ratios significantly dropped, and the ratios diminished further from late April to May onward. These results suggest that PAHs transported over the Arctic are subjected to strong photochemical degradation at polar sunrise. Although aromatic ketones decreased in spring, concentrations of some aromatic acids such as benzoic and phthalic acids increased during the course of polar sunrise, suggesting that aromatic hydrocarbons are oxidized to result in aromatic acids. However, PAHs do not act as the major source for low molecular weight (LMW) diacids such as oxalic acid that are largely formed at polar sunrise in the arctic atmosphere because PAHs are 1 to 2 orders of magnitude less abundant than LMW diacids. Correlations of trace metals with organics, their sources, and the possible role of trace transition metals are explained.

  10. VERTICAL MIXING AND CHEMISTRY OVER AN ARID URBAN SITE: FIRST RESULTS FROM AIRCRAFT OBSERVATIONS MADE DURING THE PHOENIX SUNRISE CAMPAIGN

    The role of boundary layer mixing is increasingly recognized as an important factor in determining the concentrations of ozone and other trace gases near the surface. While the concentrations at the surface can vary widely due to horizontal transport of chemical plumes, the boundary layer is also characterized by turbulence that follows a diurnal cycle in height and intensity. Surface oxidant concentrations can therefore undergo significant changes even in the absence of photochemistry. A central goal of the Phoenix 2001 Field Campaign was to study vertical mixing with the onset of convection and to quantify the effect of this mixing on chemistry within an urban boundary layer. As part of this study, a series of low altitude aircraft sampling flights were made over the Greater Phoenix area between June 16-30, 2001. The resulting observations, in conjunction with a series of surface measurements and meteorological observations, are being used to study the vertical transport and reactivity of ozone and ozone-precursors shortly after sunrise. Additional details of this campaign are given in Doran, et al. (2002). It was anticipated that turbulence over Phoenix at night would be suppressed as a result of cooling of the boundary layer over the city. By sampling shortly after sunrise, we hoped to collect measurements above the residual nocturnal stable layer and to continue sampling through the developmental period of a convectively active boundary layer. We report here on the first analysis of these observations, made from a Gulstream-1 (G-1) aircraft operated by the U.S. Department of Energy

  11. Tobacco industry attempts to frame smoking as a 'disability' under the 1990 Americans with Disabilities Act.

    2017-01-01

    Using the Truth Tobacco Industry Documents Library and Congressional records, we examined the tobacco industry's involvement with the 1990 Americans with Disabilities Act (ADA). During legislative drafting of the ADA (1989-1990), the Tobacco Institute, the tobacco industry's lobbying and public relations arm at the time, worked with industry lawyers and civil rights groups to include smoking in the ADA's definition of "disability." Focus was on smoking as a perceived rather than actual disability so that tobacco companies could maintain that smoking is not addictive. Language that would have explicitly excluded smoking from ADA coverage was weakened or omitted. Tobacco Institute lawyers did not think the argument that smokers are "disabled" would convince the courts, so in the two years after the ADA was signed into law, the Tobacco Institute paid a lawyer to conduct media tours, seminars, and write articles to convince employers that hiring only non-smokers would violate the ADA. The ultimate goal of these activities was to deter employers from promoting a healthy, tobacco-free workforce and, more broadly, to promote the social acceptability of smoking. Employers and policy makers need to be aware that tobacco use is not protected by the ADA and should not be misled by tobacco industry efforts to insinuate otherwise.

  12. Prospects for tobacco control in Zimbabwe: a historical perspective.

    Woelk, G; Mtisi, S; Vaughan, J P

    2001-09-01

    Using a historical and political economy perspective, this paper explores the prospects for tobacco control in Zimbabwe, the world's sixth largest producer and third largest tobacco exporter. Tobacco production, which first began in the former Rhodesia in the early 1900s, is closely associated with colonial history and land occupation by white settlers. The Zimbabwe (formerly Rhodesia) Tobacco Association was formed in 1928 and soon became a powerful political force. Although land redistribution has always been a central issue, it was not adequately addressed after independence in 1980, largely due to the need for Zimbabwe to gain foreign currency and safeguard employment. However, by the mid-1990s political pressures forced the government to confront the mainly white, commercial farmers with a new land acquisition policy, but intense national and international lobbying prevented its implementation. With advent of global economic changes, and following the start of a structural adjustment programme in 1991, manufacturing began to decline and the government relied even more on the earnings from tobacco exports. Thus strengthening tobacco control policies has always had a low national and public health priority. Recent illegal occupation of predominantly white owned farms, under the guise of implementing the former land redistribution policy, was politically motivated as the government faced its first major challenge at the general elections in June 2000. It remains unclear whether this will lead to long term reductions in tobacco production, although future global declines in demand could weaken the tobacco lobby. However, since Zimbabwe is only a minor consumer of tobacco, a unique opportunity does exist to develop controls on domestic cigarette consumption. To achieve this the isolated ministry of health would need considerable support from international agencies, such as the World Health Organisation and World Bank.

  13. On the evaluation of a certain class of Feynman diagrams in x-space: Sunrise-type topologies at any loop order

    2007-01-01

    We review recently developed new powerful techniques to compute a class of Feynman diagrams at any loop order, known as sunrise-type diagrams. These sunrise-type topologies have many important applications in many different fields of physics and we believe it to be timely to discuss their evaluation from a unified point of view. The method is based on the analysis of the diagrams directly in configuration space which, in the case of the sunrise-type diagrams and diagrams related to them, leads to enormous simplifications as compared to the traditional evaluation of loops in momentum space. We present explicit formulae for their analytical evaluation for arbitrary mass configurations and arbitrary dimensions at any loop order. We discuss several limiting cases in their kinematical regimes which are e.g. relevant for applications in HQET and NRQCD. We completely solve the problem of renormalization using simple formulae for the counterterms within dimensional regularization. An important application is the computation of the multi-particle phase space in D-dimensional space-time which we discuss. We present some examples of their numerical evaluation in the general case of D-dimensional space-time as well as in integer dimensions D = D 0 for different values of dimensions including the most important practical cases D 0 = 2, 3, 4. Substantial simplifications occur for odd integer space-time dimensions where the final results can be expressed in closed form through elementary functions. We discuss the use of recurrence relations naturally emerging in configuration space for the calculation of special series of integrals of the sunrise topology. We finally report on results for the computation of an extension of the basic sunrise topology, namely the spectacle topology and the topology where an irreducible loop is added

    In order to examine the response of the tropical Pacific Walker circulation (PWC) to strong tropical volcanic eruptions (SVEs), we analyzed a three-member long-term simulation performed with HadCM3, and carried out four additional CAM4 experiments. We found that the PWC shows a significant interannual weakening after SVEs. The cooling effect from SVEs is able to cool the entire tropics. However, cooling over the Maritime Continent is stronger than that over the central-eastern tropical Pacific. Thus, non-uniform zonal temperature anomalies can be seen following SVEs. As a result, the sea level pressure gradient between the tropical Pacific and the Maritime Continent is reduced, which weakens trade winds over the tropical Pacific. Therefore, the PWC is weakened during this period. At the same time, due to the cooling subtropical and midlatitude Pacific, the Intertropical Convergence Zone (ITCZ) and South Pacific convergence zone (SPCZ) are weakened and shift to the equator. These changes also contribute to the weakened PWC. Meanwhile, through the positive Bjerknes feedback, weakened trade winds cause El Niño-like SST anomalies over the tropical Pacific, which in turn further influence the PWC. Therefore, the PWC significantly weakens after SVEs. The CAM4 experiments further confirm the influences from surface cooling over the Maritime Continent and subtropical/midlatitude Pacific on the PWC. Moreover, they indicate that the stronger cooling over the Maritime Continent plays a dominant role in weakening the PWC after SVEs. In the observations, a weakened PWC and a related El Niño-like SST pattern can be found following SVEs.

  16. Tobacco-control policies in tobacco-growing states: where tobacco was king.

    Science.gov (United States)

    Fallin, Amanda; Glantz, Stanton A

    2015-06-01

    POLICY POINTS: The tobacco companies prioritized blocking tobacco-control policies in tobacco-growing states and partnered with tobacco farmers to oppose tobacco-control policies. The 1998 Master Settlement Agreement, which settled state litigation against the cigarette companies, the 2004 tobacco-quota buyout, and the companies' increasing use of foreign tobacco led to a rift between the companies and tobacco farmers. In 2003, the first comprehensive smoke-free local law was passed in a major tobacco-growing state, and there has been steady progress in the region since then. Health advocates should educate the public and policymakers on the changing reality in tobacco-growing states, notably the major reduction in the volume of tobacco produced. The 5 major tobacco-growing states (Kentucky, North Carolina, South Carolina, Tennessee, and Virginia) are disproportionately affected by the tobacco epidemic, with higher rates of smoking and smoking-induced disease. These states also have fewer smoke-free laws and lower tobacco taxes, 2 evidence-based policies that reduce tobacco use. Historically, the tobacco farmers and hospitality associations allied with the tobacco companies to oppose these policies. This research is based on 5 detailed case studies of these states, which included key informant interviews, previously secret tobacco industry documents (available at http://legacy.library.ucsf.edu), and media articles. This was supplemented with additional tobacco document and media searches specifically for this article. The tobacco companies were particularly concerned about blocking tobacco-control policies in the tobacco-growing states by promoting a pro-tobacco culture, beginning in the late 1960s. Nevertheless, since 2003, there has been rapid progress in the tobacco-growing states' passage of smoke-free laws. This progress came after the alliance between the tobacco companies and the tobacco farmers fractured and hospitality organizations stopped opposing smoke

    This report shows the results of studies related to radioactivity in tobacco and its pathways to human being. Tobacco contains high concentrations of natural radioactive materials especially polonium 210 and lead 210, which may reach a value of 27 mBq/g. The amount of polonium 210 in tobacco is related to the concentration of radon (the main source of polonium 210 in the agricultural areas) in addition to the over use of phosphate fertilizers for tobacco plantation. Radioactive materials present in tobacco enter the human body through smoking where 210 Po concentrates in the Alveolar lung; this may cause health risks including lung cancer. In addition, radiation doses due to smoking have been reported and some results of the studies carried out for radioactivity in tobacco at the Syrian Atomic Energy Commission. (author)

The program provides a fast and precise evaluation method of the Master Integrals for arbitrary (but not vanishing) masses and arbitrary value of the external momentum. Solution method: The integrals depend on three internal masses and the external momentum squared p. The method is a combination of an accelerated expansion in 1/p in its (pretty large!) region of fast convergence and of a Runge-Kutta numerical solution of a system of linear differential equations.

    Nearly 2.9 million US adolescents engaged with online tobacco marketing in 2013 to 2014. We assess whether engagement is a risk factor for tobacco use initiation, increased frequency of use, progression to poly-product use, and cessation. We analyzed data from 11 996 adolescents sampled in the nationally representative, longitudinal Population Assessment for Tobacco and Health study. At baseline (2013-2014), we ascertained respondents' engagement with online tobacco marketing. At follow-up (2014-2015), we determined if respondents had initiated tobacco use, increased frequency of use, progressed to poly-product use, or quit. Accounting for known risk factors, we fit a multivariable logistic regression model among never-users who engaged at baseline to predict initiation at follow-up. We fit similar models to predict increased frequency of use, progression to poly-product use, and cessation. Compared with adolescents who did not engage, those who engaged reported higher incidences of initiation (19.5% vs 11.9%), increased frequency of use (10.3% vs 4.4%), and progression to poly-product use (5.8% vs 2.4%), and lower incidence of cessation at follow-up (16.1% vs 21.5%). Accounting for other risk factors, engagement was positively associated with initiation (adjusted odds ratio [aOR] = 1.26; 95% confidence interval [CI]: 1.01-1.57), increased frequency of use (aOR = 1.58; 95% CI: 1.24-2.00), progression to poly-product use (aOR = 1.70; 95% CI: 1.20-2.43), and negatively associated with cessation (aOR = 0.71; 95% CI: 0.50-1.00). Engagement with online tobacco marketing represents a risk factor for adolescent tobacco use. FDA marketing regulation and cooperation of social-networking sites could limit engagement.

    2015-12-01

    During the recovery phase of the 22-23 June 2015 superstorm multiple DMSP spacecraft observed two separate and short-lived (~ 30 minutes) events of localized cooling in the topside equatorial ionosphere (~840 km) in the post-sunrise region (between 6:15 and 7:30 local time). The ion temperatures dropped from the nominal 2000-3000° observed in these regions to 1000 to 1500°. This cooling effect was not observed on the corresponding duskside equatorial crossings of the DMSP spacecraft during this storm. Further, these cooling events do not normally occur during major storms; no such phenomenon was observed by DMSP during the March 2015 superstorm. Flow data from DMSP and the CINDI instruments on the C/NOFS spacecraft indicate these cooling events are associated with short-lived vertical flows bringing up cooler plasma from lower altitudes. The two cooling events correspond to large northward turnings of the IMF during the storm and these are being explored as a possible trigger mechanism.

    2010-02-01

    Full Text Available Tobacco use is the first preventable cause of death. This is associated not only with physical illness and a shorter life expectancy, but also with different mental disorders such as anxiety disorders. Given the low risk perception of use, this paper reports a systematic review of the scientific literature on the relationship between anxiety and tobacco from an emotional perspective, including data on smoking prevalence, factors associated with the onset and maintenance of tobacco use, as well as those factors that hamper smoking cessation and increase relapse rates. The high rates of comorbidity between tobacco use and anxiety disorders make necessary the development of new and better tobacco cessation treatments, especially designed for those smokers with high state anxiety or anxiety sensitivity, with the aim of maximizing the efficacy.

    Tobacco use is the largest single preventable cause of death and disease worldwide. Standardised tobacco packaging is an intervention intended to reduce the promotional appeal of packs and can be defined as packaging with a uniform colour (and in some cases shape and size) with no logos or branding, apart from health warnings and other government-mandated information, and the brand name in a prescribed uniform font, colour and size. Australia was the first country to implement standardised tobacco packaging between October and December 2012, France implemented standardised tobacco packaging on 1 January 2017 and several other countries are implementing, or intending to implement, standardised tobacco packaging. To assess the effect of standardised tobacco packaging on tobacco use uptake, cessation and reduction. We searched MEDLINE, Embase, PsycINFO and six other databases from 1980 to January 2016. We checked bibliographies and contacted study authors to identify additional peer-reviewed studies. Primary outcomes included changes in tobacco use prevalence incorporating tobacco use uptake, cessation, consumption and relapse prevention. Secondary outcomes covered intermediate outcomes that can be measured and are relevant to tobacco use uptake, cessation or reduction. We considered multiple study designs: randomised controlled trials, quasi-experimental and experimental studies, observational cross-sectional and cohort studies. The review focused on all populations and people of any age; to be included, studies had to be published in peer-reviewed journals. We examined studies that assessed the impact of changes in tobacco packaging such as colour, design, size and type of health warnings on the packs in relation to branded packaging. In experiments, the control condition was branded tobacco packaging but could include variations of standardised packaging. Screening and data extraction followed standard Cochrane methods. We used different 'Risk of bias' domains for

    Full Text Available Earthquakes are the result of slip along faults and are due to the decrease of rock frictional strength (dynamic weakening with increasing slip and slip rate. Friction experiments simulating the abrupt accelerations (>>10 m/s2, slip rates (~1 m/s, and normal stresses (>>10 MPa expected at the passage of the earthquake rupture along the front of fault patches, measured large fault dynamic weakening for slip rates larger than a critical velocity of 0.01–0.1 m/s. The dynamic weakening corresponds to a decrease of the friction coefficient (defined as the ratio of shear stress vs. normal stress up to 40%–50% after few millimetres of slip (flash weakening, almost independently of rock type. The microstructural evolution of the sliding interfaces with slip may yield hints on the microphysical processes responsible for flash weakening. At the microscopic scale, the frictional strength results from the interaction of micro- to nano-scale surface irregularities (asperities which deform during fault sliding. During flash weakening, the visco-plastic and brittle work on the asperities results in abrupt frictional heating (flash heating and grain size reduction associated with mechano-chemical reactions (e.g., decarbonation in CO2-bearing minerals such as calcite and dolomite; dehydration in water-bearing minerals such as clays, serpentine, etc. and phase transitions (e.g., flash melting in silicate-bearing rocks. However, flash weakening is also associated with grain size reduction down to the nanoscale. Using focused ion beam scanning and transmission electron microscopy, we studied the micro-physical mechanisms associated with flash heating and nanograin formation in carbonate-bearing fault rocks. Experiments were conducted on pre-cut Carrara marble (99.9% calcite cylinders using a rotary shear apparatus at conditions relevant to seismic rupture propagation. Flash heating and weakening in calcite-bearing rocks is associated with a shock-like stress

  9. Direct weakening of tropical circulations from masked CO2 radiative forcing.

    Merlis, Timothy M

    2015-10-27

    Climate models robustly simulate weakened mean circulations of the tropical atmosphere in direct response to increased carbon dioxide (CO2). The direct response to CO2, defined by the response to radiative forcing in the absence of changes in sea surface temperature, affects tropical precipitation and tropical cyclone genesis, and these changes have been tied to the weakening of the mean tropical circulation. The mechanism underlying this direct CO2-forced circulation change has not been elucidated. Here, I demonstrate that this circulation weakening results from spatial structure in CO2's radiative forcing. In regions of ascending circulation, such as the intertropical convergence zone, the CO2 radiative forcing is reduced, or "masked," by deep-convective clouds and high humidity; in subsiding regions, such as the subtropics, the CO2 radiative forcing is larger because the atmosphere is drier and deep-convective clouds are infrequent. The spatial structure of the radiative forcing reduces the need for the atmosphere to transport energy. This, in turn, weakens the mass overturning of the tropical circulation. The previously unidentified mechanism is demonstrated in a hierarchy of atmospheric general circulation model simulations with altered radiative transfer to suppress the cloud masking of the radiative forcing. The mechanism depends on the climatological distribution of clouds and humidity, rather than uncertain changes in these quantities.

  11. Strong Velocity-Weakening of Nanograins at High Slip-Rates

    Science.gov (United States)

    Han, R.; Hirose, T.; Ando, J.

    2008-12-01

    It has been observed that slip localization zones in some experimental and natural faults consist of crystalline or amorphous nanograins of different minerals. Prolonged grinding of silicate rocks (e.g., quartz rock and granite) is known to produce amorphous silica nanograins and mechanical properties of the material (especially under wet condition) have been attributed to a mechanism of fault weakening. Also, recent high- velocity friction tests on carbonate rocks showed that faults can be weakened by thermal decomposition of calcite into nanograins of lime and carbon dioxide and the lubrication effect of the nanograins would be critical for the fault weakening. However, mechanical behavior(s) and friction mechanism(s) of fault slip zones with nanograins, especially at high slip-rates, are still poorly understood, despite their potential importance to the understanding of seismic faulting. In this contribution, we show you our experimental results indicating velocity-weakening of nanograins (probably caused by still unknown mechanical behaviors of nanograins) rather than by temperature-related weakening behavior. In our high-velocity friction tests on Carrara marble at seismic slip-rates, we have tried to "cool" the simulated fault with liquid nitrogen and compressed air during frictional sliding, and found, in the simulated fault coated with nanopowders of lime (CaO) formed by thermal decomposition, no correlation between friction and temperature measured with thermocouples (i.e., no temperature-related weakening behavior), although strong "velocity-weakening" behavior appeared. The observation was confirmed by another experiment: from (1) the calculated "maximum" sliding surface temperature [Carslaw and Jaeger, 1959] using the mechanical data, with an assumption of strong slip localization into a very thin layer, and (2) the measured temperature with thermocouples at a place just below the sliding surface and close to the periphery of the specimen, it was found

    Despite decades of industry innovation and regulatory efforts, the harmfulness of conventional cigarettes has not changed. There are several pitfalls in this area, including the long time lag before health impacts of product regulatory changes become apparent, the danger of consumers deriving false reassurance of lesser harm in the interim period, the lack of relevant expertise and the lack of an internationally agreed and evidence-based strategic approach. Articles 9 and 10 of the Framework Convention on Tobacco Control provide the potential for such a global strategy, and knowledge and research has increased significantly over recent years. However, there are huge opportunity costs in implementing product disclosure and regulatory strategies: most national regulators have very limited human and financial resources, which should be focused on other evidence-based tobacco control interventions. We believe therefore that it is now time to abandon the notion of safe or safer cigarettes while moving consumers towards cleaner nicotine products as soon as possible. In parallel to this, we recommend a number of other strategies be implemented including: reducing the appeal of all tobacco products, forbidding new tobacco products or brand variants being marketed without evidence of reduced harm, appeal or addictiveness, and developing a tobacco industry resourced, but industry independent, Framework Convention on Tobacco Control global repository to assist national regulators in understanding and regulating the products on their markets.

  20. Slow oil shocks and the 'weakening of the oil price-macroeconomy relationship'

    2010-01-01

    Many papers have been documenting and analysing the asymmetry and the weakening of the oil price-macroeconomy relationship as off the early eighties. While there seems to be a consensus about the factors causing the asymmetry, namely adjustment costs which offset the benefits of low energy prices, the debate about the weakening of the relationship is not over yet. Moreover, the alternative oil price specifications which have been proposed by, and to restore the stability of the relationship fail to Granger cause output or unemployment in post-1980 data. By using the concept of accelerations of the oil price, we show that the weakening of this relationship corresponds to the appearance of slow oil price increases, which have less impact on the economy. When filtering out these slow oil price variations from the sample, we manage to rehabilitate the causality running from the oil price to the macroeconomy and show that far from weakening, the oil price accelerations-GDP relationship has even been growing stronger since the early eighties.

  4. Whisker Deprivation Drives Two Phases of Inhibitory Synapse Weakening in Layer 4 of Rat Somatosensory Cortex.

    Directory of Open Access Journals (Sweden)

    Melanie A Gainey

    Full Text Available Inhibitory synapse development in sensory neocortex is experience-dependent, with sustained sensory deprivation yielding fewer and weaker inhibitory synapses. Whether this represents arrest of synapse maturation, or a more complex set of processes, is unclear. To test this, we measured the dynamics of inhibitory synapse development in layer 4 of rat somatosensory cortex (S1 during continuous whisker deprivation from postnatal day 7, and in age-matched controls. In deprived columns, spontaneous miniature inhibitory postsynaptic currents (mIPSCs and evoked IPSCs developed normally until P15, when IPSC amplitude transiently decreased, recovering by P16 despite ongoing deprivation. IPSCs remained normal until P22, when a second, sustained phase of weakening began. Delaying deprivation onset by 5 days prevented the P15 weakening. Both early and late phase weakening involved measurable reduction in IPSC amplitude relative to prior time points. Thus, deprivation appears to drive two distinct phases of active IPSC weakening, rather than simple arrest of synapse maturation.

    Describe the extent to which tobacco industry marketing tactics incorporated American Indian culture and traditional tobacco. A keyword search of industry documents was conducted using document archives from the Truth Tobacco Documents Library. Tobacco industry documents (n=76) were analysed for themes. Tobacco industry marketing tactics have incorporated American Indian culture and traditional tobacco since at least the 1930s, with these tactics prominently highlighted during the 1990s with Natural American Spirit cigarettes. Documents revealed the use of American Indian imagery such as traditional headdresses and other cultural symbols in product branding and the portrayal of harmful stereotypes of Native people in advertising. The historical and cultural significance of traditional tobacco was used to validate commercially available tobacco. The tobacco industry has misappropriated culture and traditional tobacco by misrepresenting American Indian traditions, values and beliefs to market and sell their products for profit. Findings underscore the need for ongoing monitoring of tobacco industry marketing tactics directed at exploiting Native culture and counter-marketing tactics that raise awareness about the distinction between commercial and traditional tobacco use. Such efforts should be embedded within a culturally sensitive framework to reduce the burden of commercial tobacco use. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  7. The Role of Compliance and Reaction Rate in Dehydration Weakening and Frictional Stability of Antigorite

    Science.gov (United States)

    Burdette, E.; Okazaki, K.; Hirth, G.

    2017-12-01

    The complicated brittle-ductile rheology of antigorite at subduction zone pressures and temperatures, resulting from its anisotropic mechanical properties, low dehydration temperature, and high water content has made interpretation of dehydration weakening problematic. Recent analyses indicate that antigorite is both ductile and brittle at high temperatures, and follows effective pressure frictional laws while dehydrating. In this study we focus on the role of rig compliance and reaction kinetics on frictional weakening and frictional stability. In addition, we correlate the evolution of mechanical behavior with AE activity at conditions within and above the thermal stability limit of antigorite. We conducted experiments at confining pressures from 0.25 GPa to 1GPa in a Griggs apparatus and modified rig compliance by including compliant components within the loading frame. We also modeled in-situ reaction progress using parameters from Sawai et al. (2013) to quantify relationships between weakening and fluid production. Without modifying the compliance, low pressure runs show stable dehydration weakening. With a modified, low compliance, results were nearly identical to stable weakening at standard compliance at 1 GPa. However, at lower pressures, many acoustic emissions were recorded at peak reaction rates during temperature ramping, with a rapid failure event occurring several minutes afterward (with the caveat that we still need to verify that AEs occur within the sample). No AEs are observed during room temperature experiments in samples that fault, nor were any observed in the high temperature experiments at conditions within the antigorite stability field - consistent with prior studies. Our results demonstrate that understanding in-situ dehydration reaction kinetics and their feedback with rheology and system compliance are key to scaling laboratory antigorite rheology to earth.

    Tobacco is an important cash crop in Pakistan. It is a sensitive plant, prone to bacterial, fungal and viral diseases. Therefore, high levels of pesticides are used to grow tobacco. Many of these pesticides are highly toxic and have profound impacts not only on the smokers but also on the lives of tobacco farmers, their families and the environment. The environmental impacts of tobacco crop start right from its seedlings stage till throwing away of cigarette filters. These impacts are divided into three stages: (a) Environmental impacts at the tobacco growing stage, (b) Environmental impacts at tobacco manufacturing/processing stage, and (c) Environmental impacts of the tobacco use. This paper provides information of environmental impacts of tobacco crop at all the above-mentioned three stages and recommends measures for mitigation. (author)

  17. Weakened cyclones, intensified anticyclones and recent extreme cold winter weather events in Eurasia

    Zhang Xiangdong; Lu Chuhan; Guan Zhaoyong

    2012-01-01

    Extreme cold winter weather events over Eurasia have occurred more frequently in recent years in spite of a warming global climate. To gain further insight into this regional mismatch with the global mean warming trend, we analyzed winter cyclone and anticyclone activities, and their interplay with the regional atmospheric circulation pattern characterized by the semi-permanent Siberian high. We found a persistent weakening of both cyclones and anticyclones between the 1990s and early 2000s, and a pronounced intensification of anticyclone activity afterwards. It is suggested that this intensified anticyclone activity drives the substantially strengthening and northwestward shifting/expanding Siberian high, and explains the decreased midlatitude Eurasian surface air temperature and the increased frequency of cold weather events. The weakened tropospheric midlatitude westerlies in the context of the intensified anticyclones would reduce the eastward propagation speed of Rossby waves, favoring persistence and further intensification of surface anticyclone systems.

  18. On the relative significance of lithospheric weakening mechanisms for sustained plate tectonics

    Science.gov (United States)

    Araceli Sanchez-Maes, Sophia

    2018-01-01

    Plate tectonics requires the bending of strong plates at subduction zones, which is difficult to achieve without a secondary weakening mechanism. Two classes of weakening mechanisms have been proposed for the generation of ongoing plate tectonics, distinguished by whether or not they require water. Here we show that the energy budget of global subduction zones offers a simple yet decisive test on their relative significance. Theoretical studies of mantle convection suggest bending dissipation to occupy only 10-20 % of total dissipation in the mantle, and our results indicate that the hydrous mechanism in the shallow part of plates is essential to satisfy the requirement. Thus, surface oceans are required for the long-term operation of plate tectonics on terrestrial worlds. Establishing this necessary and observable condition for sustained plate tectonics carries important implications for planetary habitability at large.

    Lucas, Antoine; Mangeney, Anne; Ampuero, Jean Paul

    2014-03-04

    One of the ultimate goals in landslide hazard assessment is to predict maximum landslide extension and velocity. Despite much work, the physical processes governing energy dissipation during these natural granular flows remain uncertain. Field observations show that large landslides travel over unexpectedly long distances, suggesting low dissipation. Numerical simulations of landslides require a small friction coefficient to reproduce the extension of their deposits. Here, based on analytical and numerical solutions for granular flows constrained by remote-sensing observations, we develop a consistent method to estimate the effective friction coefficient of landslides. This method uses a constant basal friction coefficient that reproduces the first-order landslide properties. We show that friction decreases with increasing volume or, more fundamentally, with increasing sliding velocity. Inspired by frictional weakening mechanisms thought to operate during earthquakes, we propose an empirical velocity-weakening friction law under a unifying phenomenological framework applicable to small and large landslides observed on Earth and beyond.

    2008-06-01

    The visual system can complete coloured surfaces from stimulus fragments, inducing the subjective perception of a colour-spread figure. Negative afterimages of these induced colours were first reported by S. Shimojo, Y. Kamitani, and S. Nishida (2001). Two experiments were conducted to examine the effect of attention on the duration of these afterimages. The results showed that shifting attention to the colour-spread figure during the adaptation phase weakened the subsequent afterimage. On the basis of previous findings that the duration of these afterimages is correlated with the strength of perceptual filling-in (grouping) among local inducers during the adaptation phase, it is proposed that attention weakens perceptual filling-in during the adaptation phase and thereby prevents the stimulus from being segmented into an illusory figure.

  4. Dynamic weakening of serpentinite gouges and bare surfaces at seismic slip rates

    2014-11-01

    To investigate differences in the frictional behavior between initially bare rock surfaces of serpentinite and powdered serpentinite ("gouge") at subseismic to seismic slip rates, we conducted single-velocity step and multiple-velocity step friction experiments on an antigorite-rich and lizardite-rich serpentinite at slip rates (V) from 0.003 m/s to 6.5 m/s, sliding displacements up to 1.6 m, and normal stresses (σn) up to 22 MPa for gouge and 97 MPa for bare surfaces. Nominal steady state friction values (μnss) in gouge at V = 1 m/s are larger than in bare surfaces for all σn tested and demonstrate a strong σn dependence; μnss decreased from 0.51 at 4.0 MPa to 0.39 at 22.4 MPa. Conversely, μnss values for bare surfaces remained ~0.1 with increasing σn and V. Additionally, the velocity at the onset of frictional weakening and the amount of slip prior to weakening were orders of magnitude larger in gouge than in bare surfaces. Extrapolation of the normal stress dependence for μnss suggests that the behavior of antigorite gouge approaches that of bare surfaces at σn ≥ 60 MPa. X-ray diffraction revealed dehydration reaction products in samples that frictionally weakened. Microstructural analysis revealed highly localized slip zones with melt-like textures in some cases gouge experiments and in all bare surfaces experiments for V ≥ 1 m/s. One-dimensional thermal modeling indicates that flash heating causes frictional weakening in both bare surfaces and gouge. Friction values for gouge decrease at higher velocities and after longer displacements than bare surfaces because strain is more distributed.

    A significant reduction in the coefficient of friction of rock can occur if sliding velocity approaches seismic rates as a consequence of weakening of microscopic sliding contacts by flash heating. Using a high-acceleration and -speed biaxial apparatus equipped with a high-speed Infra-Red (IR) camera to capture thermographs of the sliding surface, we have documented the heterogeneous distribution of temperature on flash-heated decimetric surfaces characterized by linear arrays of high-temperature, mm-size spots, and streaks. Numerical models that are informed by the character of flash heated surfaces and that consider the coupling of changes in temperature and changes in the friction of contacts, supports the hypothesis that independent mechanisms of flash weakening operate at different contact scales. Here, we report on new experiments that provide additional constraints on the life-times and rest-times of populations of millimeter-scale contacts. Rock friction experiments conducted on Westerly granite samples in a double-direct shear configuration achieve velocity steps from 1 mm/s to 900 mm/s at 100g accelerations over 2 mm of displacement with normal stresses of 22-36 MPa and 30 mm of displacement during sustained high-speed sliding. Sliding surfaces are machined to roughness similar to natural fault surfaces and that allow us to control the characteristics of millimeter-scale contact populations. Thermographs of the sliding surface show temperatures up to 200 C on millimeter-scale contacts, in agreement with 1-D heat conduction model estimates of 180 C. Preliminary comparison of thermal modeling results and experiment observations demonstrate that we can distinguish the different life-times and rest-times of contacts in thermographs and the corresponding frictional weakening behaviors. Continued work on machined surfaces that lead to different contact population characteristics will be used to test the multi-scale and multi-mechanism hypothesis for flash

    In the face of increasing media restrictions around the world, point-of-purchase promotion (also called point-of-sale merchandising, and frequently abbreviated as POP or POS) is now one of the most important tools that tobacco companies have for promoting tobacco products. Using tobacco industry documents, this paper demonstrates that tobacco companies have used point-of-purchase promotion in response to real or anticipated advertising restrictions. Their goal was to secure dominance in the retail setting, and this was achieved through well-trained sales representatives who offered contracts for promotional incentive programmes to retailers, which included the use of point-of-sale displays and merchandising fixtures. Audit programmes played an important role in ensuring contract enforcement and compliance with a variety of tobacco company incentive programmes. Tobacco companies celebrated their merchandising successes, in recognition of the stiff competition that existed among tobacco companies for valuable retail display space.

    Full Text Available This paper presents a simplified fuzzy logic-based speed control scheme of an interior permanent magnet synchronous motor (IPMSM above the base speed using a flux-weakening method. In this work, nonlinear expressions of d-axis and q-axis currents of the IPMSM have been derived and subsequently incorporated in the control algorithm for the practical purpose in order to implement fuzzy-based flux-weakening strategy to operate the motor above the base speed. The fundamentals of fuzzy logic algorithms as related to motor control applications are also illustrated. A simplified fuzzy speed controller (FLC for the IPMSM drive has been designed and incorporated in the drive system to maintain high performance standards. The efficacy of the proposed simplified FLC-based IPMSM drive is verified by simulation at various dynamic operating conditions. The simplified FLC is found to be robust and efficient. Laboratory test results of proportional integral (PI controller-based IPMSM drive have been compared with the simulated results of fuzzy controller-based flux-weakening IPMSM drive system.

  9. Design and Optimization of IPM Motor Considering Flux Weakening Capability and Vibration for Electric Vehicle Applications

    Full Text Available As motor design is key to the development of electric vehicles (EVs and hybrid EVs (HEVs, it has recently become the subject of considerable interest. Interior permanent magnet (IPM motors offer advantages such as high torque density and high efficiency, benefiting from both permanent magnet (PM torque and reluctance torque. However an obvious disadvantage of IPM motors is that operation at high speed involves difficulties in achieving the required flux-weakening capability and low vibration. This study focuses on optimizing the flux-weakening performance and reducing the vibration of an IPM motor for EVs. Firstly, flux-weakening capability, cogging torque, torque ripple, and radical vibration force are analyzed based on the mathematical model. Secondly, three kinds of motors are optimized by the genetic algorithm and analyzed, providing visible insights into the contribution of different rotor structures to the torque characteristics, efficiency, and extended speed range. Thirdly, a slotted rotor configuration is proposed to reduce the torque ripple and radical vibration force. The flux density distributions are discussed, explaining the principle that motors with slotted rotors and stator skew slots have smaller torque ripple and radical vibration force. Lastly, the design and optimization results have been validated against experiments.

    Multibeam bathymetric system (MBS) has been widely applied in the marine surveying for providing high-resolution seabed topography. However, some factors degrade the precision of bathymetry, including the sound velocity, the vessel attitude, the misalignment angle of the transducer and so on. Although these factors have been corrected strictly in bathymetric data processing, the final bathymetric result is still affected by their residual errors. In deep water, the result usually cannot meet the requirements of high-precision seabed topography. The combined effect of these residual errors is systematic, and it's difficult to separate and weaken the effect using traditional single-error correction methods. Therefore, the paper puts forward a new method for weakening the effect of residual errors based on the frequency-spectrum characteristics of seabed topography and multibeam bathymetric data. Four steps, namely the separation of the low-frequency and the high-frequency part of bathymetric data, the reconstruction of the trend of actual seabed topography, the merging of the actual trend and the extracted microtopography, and the accuracy evaluation, are involved in the method. Experiment results prove that the proposed method could weaken the combined effect of residual errors on multibeam bathymetric data and efficiently improve the accuracy of the final post-processing results. We suggest that the method should be widely applied to MBS data processing in deep water.

    Full Text Available OBJECTIVES: This in vitro study evaluated the fracture resistance of weakened human premolars (MOD cavity preparation and pulp chamber roof removal restored with condensable resin composite with and without cusp coverage. MATERIAL AND METHODS: Thirty human maxillary premolars were divided into three groups: Group A (control, sound teeth; Group B, wide MOD cavities prepared and the pulp chamber roof removed and restored with resin composite without cusp coverage; Group C, same as Group B with 2.0 mm of buccal and palatal cusps reduced and restored with the same resin. The teeth were included in metal rings with self-curing acrylic resin, stored in water for 24 h and thereafter subjected to a compressive axial load in a universal testing machine at 0.5 mm/min. RESULTS: The mean fracture resistance values ± standart deviation (kgf were: group A: 151.40 ± 55.32, group B: 60.54 ± 12.61, group C: 141.90 ± 30.82. Statistically significant differences were found only between Group B and the other groups (p<0.05. The condensable resin restoration of weakened human premolars with cusp coverage significantly increased the fracture resistance of the teeth as compared to teeth restored without cusp coverage. CONCLUSION: The results showed that cusp coverage with condensable resin might be a safe option for restoring weakened endodontically treated teeth.

    Full Text Available Background: It is thought that price increase in tobacco products leads to reduced consumption. Though many studies have substantiated this concept, it has not been well studied in India. Recently, price of tobacco products was increased due to ban on plastic sachets of chewing tobacco and increased tax in Rajasthan. This study was designed to evaluate the effect of price rise on overall consumption of tobacco in Jaipur city, Rajasthan. Materials and Methods: This study was carried out in Jaipur city. Two-staged stratified sampling was used. In the first phase of study, cost and consumption of various tobacco products in the months of February and April were enquired from 25 retail tobacco shops. In the second phase, tobacco consumption was enquired from 20 consecutive consumers purchasing any tobacco product from all the above retail tobacco shops. The data were statistically analyzed using descriptive statistics and paired "t" test. Results: The comparison of prices of tobacco products between February and April revealed that the price of cigarette, bidi, and chewing tobacco has increased by 19%, 21%, and 68%, respectively. Average decrease in sales of cigarettes, bidi, and chewing tobacco at shops included in the study were 14%, 23%, and 38%, respectively. The consumers purchasing tobacco also reported decreased consumption. Chewing tobacco showed the maximum reduction (21%. Consumption of cigarette and bidi has also reduced by 15% and 13%, respectively. Conclusion: It may be concluded that reduction in consumption is associated with increased price of tobacco products. Reduced consumption is comparative to the magnitude of price increase.

    Full Text Available Energy production from biomass can reduce „greenhouse effect” and contribute to solving energy security especially in the agricultural households which rely on energy from fossil fuels. In Croatia fuel-cured tobacco is produced on about 5000 ha. Gross income for the whole production is about 180 000 000 kn/year. Flue-cured tobacco is a high energy consuming crop. There are two parts of energy consumption, for mechanization used for the field production (11% and, energy for bulk-curing (89%. In each case, presently used fuels of fossil origin need to be substituted by an alternative energy source of organic origin. Hereafter attention is paid to finding a more economic and ecologically acceptable fuel for curing tobacco. Curing flue-cured tobacco is done by heated air in curing burns. Various sources of heat have been used; wood, coal, oil and gas. In each case different burning facilities of different efficiency have been used. This has had an impact on curing costs and ecology. Recently, mostly used fuel has been natural gas. However, gas is getting expensive. Consequently, an alternative fuel for curing tobacco is sought for. According to literature, agricultural crops suitable for the latter purpose could be wheat, barley, maize, sorghum, sugar beet and some other annual and perennial plant species. Wooden pellets (by-products are suitable for combustion too. Ligno-cellulose fuels have been used for heating since long time. However, not sufficient research has been done from an applied point of view (Venturi and Venturi, 2003. Fuel combustion is getting more efficient with developing technological innovations. The curing barn manufacturers are offering technology for combusting wooden pellets (by-products for curing tobacco. The pellets are available on domestic market. The same technology can be used for combustion of maize grain. Within “Hrvatski duhani” research on suitability of using wooden pellets and maize grain and whole

    Implementing the World Health Organisation (WHO) Framework Convention on Tobacco Control (FCTC) relies heavily on enforcement. Little is known of the way different enforcement agencies operate, prioritise or network. A questionnaire was sent to representatives of the International Federation of Environmental Health (IFEH) in 36 countries. Tobacco control was given low priority. Almost two thirds did not have any tobacco control policy. A third reported their organisation had worked with other agencies on tobacco control. Obstacles to addressing tobacco control included a lack of resources (61%) and absence of a coherent strategy (39%).

    Strain localization is an ubiquitous process in earth materials observed over a broad range of scales in space and time. Localized deformation and the formation of shear zones and faults typically involves material softening by various processes, like shear heating and grain size reduction. Numerical modeling enables us to study the complex physical and chemical weakening processes by separating the effect of individual parameters and boundary conditions. Using simple piece-wise linear functions for the parametrization of weakening processes allows studying a system at a chosen (lower) level of complexity (e.g. Cyprych et al., 2016). In this study, we utilize a finite element model to test two weakening laws that reduce the strength of the material depending on either the I) amount of accumulated strain or II) deformational work. Our 2D Cartesian models are benchmarked to single inclusion torsion experiments performed at elevated temperatures of 900 °C and pressures of up to 400 MPa (Rybacki et al., 2014). The experiments were performed on Carrara marble samples containing a weak Solnhofen limestone inclusion at a maximum strain rate of 2.0*10-4 s-1. Our models are designed to reproduce shear deformation of a hollow cylinder equivalent to the laboratory setup, such that material leaving one side of the model in shear direction enters again on the opposite side using periodic boundary conditions. Similar to the laboratory tests, we applied constant strain rate and constant stress boundary conditions.We use our model to investigate the time-dependent distribution of stress and strain and the effect of different parameters. For instance, inclusion rotation is shown to be strongly dependent on the viscosity ratio between matrix and inclusion and stronger ductile weakening increases the localization rate while decreasing shear zone width. The most suitable weakening law for representation of ductile rock is determined by combining the results of parameter tests with

    Gender differences in overall tobacco use clearly exist. In general, men are more likely to use tobacco products than are women. However, this simple generalization, ignoring type of tobacco products, time, and culture, masks many more interesting gender differences in tobacco use. There are pronounced gender differences in tobacco use of specific tobacco products within some cultures but not others. Yet these differences have changed across time, including narrowing and widening of this gender gap, depending on culture and tobacco product. This article addresses these issues and presents possible psychosocial, biological, and psychobiological explanations for these phenomena. In addition, the implications of these differences and ways to learn more about these important differences are discussed.

    To review how tobacco transnational companies conducted their business in the hostile environment of Singapore, attempting to counter some of the government's tobacco control measures; to compare the Malaysian and the Singaporean governments' stance on tobacco control and the direct bearing of this on the way the tobacco companies conduct their business. Systematic keyword and opportunistic website searches of formerly private internal industry documents. The comprehensive prohibition on advertising did not prevent the companies from advertising cigarettes to Singaporeans. Both British American Tobacco and Philip Morris used Malaysian television to advertise into Singapore. To launch a new brand of cigarettes, Alpine, Philip Morris used a non-tobacco product, the Alpine wine cooler. Other creative strategies such as innovative packaging and display units at retailers were explored to overcome the restrictions. Philip Morris experimented with developing a prototype cigarette using aroma and sweetened tipping paper to target the young and health conscious. The industry sought to weaken the strong pack warnings. The industry distributed anti-smoking posters for youth to retailers but privately salivated over their market potential.

    Recent studies have described tobacco advertising in the print media, on billboards, and through sponsorship of cultural and sporting events. However, little attention has been given to another common and unavoidable source of tobacco advertising, that which is encountered in retail stores. In July 1987, we conducted a survey of 61 packaged goods retail stores in Buffalo, NY, to assess the prevalence and type of point-of-sale tobacco advertising. In addition, store owners or managers were surveyed to determine their store's policy regarding tobacco advertising, receipt of monetary incentives from distributors for displaying tobacco ads, and willingness to display antitobacco ads. Six types of stores were involved in the study: 10 supermarkets, 10 privately owned grocery stores, 9 chain convenience food stores that do not sell gasoline, 11 chain convenience food stores that sell gasoline, 11 chain pharmacies, and 10 private pharmacies. Two-thirds of the stores displayed tobacco posters, and 87 percent had promotional items advertising tobacco products, primarily cigarettes. Larger stores, and those that were privately owned, tended to display more posters and promotional items. Eighty percent of tobacco product displays were for cigarettes, 16 percent for smokeless tobacco products, and 4 percent for cigars and pipe tobacco. Convenience stores selling gasoline had the most separate tobacco product displays. Of tobacco product displays, 24 percent were located adjacent to candy and snack displays. Twenty-nine of the 61 store owners or managers indicated that their store had a policy regulating the display of tobacco ads and tobacco product displays.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1910192

  2. Tobacco industry strategies for influencing European Community tobacco advertising legislation.

    Restrictions on tobacco company advertising and sponsorship are effective parts of tobacco control programmes worldwide. Through Council Directive 98/43/EC, the European Community (EC) sought to end all tobacco advertising and sponsorship in EC member states by 2006. Initially proposed in 1989, the directive was adopted in 1998, and was annulled by the European Court of Justice in 2000 following a protracted lobbying campaign against the directive by a number of interested organisations including European tobacco companies. A new advertising directive was proposed in May, 2001. We reviewed online collections of tobacco industry documents from US tobacco companies made public under the US Master Settlement Agreement of 1998. Documents reviewed dated from 1978 to 1994 and came from Philip Morris, R J Reynolds, and Brown and Williamson (British American Tobacco) collections. We also obtained approximately 15,000 pages of paper records related to British American Tobacco from its documents' depository in Guildford, UK. This information was supplemented with information in the published literature and consultations with European tobacco control experts. The tobacco industry lobbied against Directive 98/43/EC at the level of EC member state governments as well as on a pan-European level. The industry sought to prevent passage of the directive within the EC legislature, to substitute industry-authored proposals in place of the original directive, and if necessary to use litigation to prevent implementation of the directive after its passage. The tobacco industry sought to delay, and eventually defeat, the EC directive on tobacco advertising and sponsorship by seeking to enlist the aid of figures at the highest levels of European politics while at times attempting to conceal the industry's role. An understanding of these proposed strategies can help European health advocates to pass and implement effective future tobacco control legislation.

    Introduction: Tobacco product testing is a critical component of the Family Smoking Prevention and Tobacco Control Act (FSPTCA), which grants the Food and Drug Administration the authority to regulate tobacco products. The availability of methods and measures that can provide accurate data on the relative health risks across types of tobacco products, brands, and subbrands of tobacco products on the validity of any health claims associated with a product, and on how consumers perceive information on products toxicity or risks is crucial for making decisions on the product's potential impact on public health. These tools are also necessary for making assessments of the impact of new indications for medicinal products (other than cessation) but more importantly of tobacco products that may in the future be marketed as cessation tools. Objective: To identify research opportunities to develop empirically based and comprehensive methods and measures for testing tobacco and other nicotine-containing products so that the best science is available when decisions are made about products or policies. Methods: Literature was reviewed to address sections of the FSPTCA relevant to tobacco product evaluation; research questions were generated and then reviewed by a committee of research experts. Results: A research agenda was developed for tobacco product evaluation in the general areas of toxicity and health risks, abuse liability, consumer perception, and population effects. Conclusion: A cohesive, systematic, and comprehensive assessment of tobacco products is important and will require building consensus and addressing some crucial research questions. PMID:21460383

    This paper reviews how the tobacco industry is promoting its products online and examines possible regulation models to limit exposure to this form of marketing. Opportunities to use new media to advance tobacco control are also discussed and future research possibilities are proposed. Published articles and grey literature reports were identified through searches of the electronic databases, PUBMED and Google Scholar using a combination of the following search terms: tobacco or smoking and new media, online media, social media, internet media, Web 2.0, Facebook, YouTube and Twitter. A possible obstacle to fully realising the benefits of regulating tobacco marketing activities and effectively communicating tobacco control messages is the rapid evolution of the media landscape. New media also offer the tobacco industry a powerful and efficient channel for rapidly countering the denormalising strategies and policies of tobacco control. Evidence of tobacco promotion through online media is emerging, with YouTube being the most researched social media site in the tobacco control field. The explosive rise in Internet use and the shift to these new media being driven by consumer generated content through social platforms may mean that fresh approaches to regulating tobacco industry marketing are needed.

    To review strategies of transnational tobacco companies (TTCs) at creating a favourable advertising environment for their products in Hungary, with special regard to efforts resulting in the liberalisation of tobacco advertising in 1997. Analysis of internal tobacco industry documents relevant to Hungary available on the World Wide Web. Transcripts of speeches of members of the Parliament during the debate of the 1997 advertising act were also reviewed. The tobacco companies not only entered the Hungarian market by early participation in the privatisation of the former state tobacco monopoly, but also imported theirsophisticated marketing experiences. Evasion and violation of rules in force, creation of new partnerships, establishment and use of front groups, finding effective ways for influencing decision makers were all parts of a well orchestrated industry effort to avoid a strict marketing regulation for tobacco products.

    Ellerman Bombs are signatures of magnetic reconnection, which is an important physical process in the solar atmosphere. How and where they occur is a subject of debate. In this paper, we analyze Sunrise/IMaX data, along with 3D MHD simulations that aim to reproduce the exact scenario proposed for the formation of these features. Although the observed event seems to be more dynamic and violent than the simulated one, simulations clearly confirm the basic scenario for the production of EBs. The simulations also reveal the full complexity of the underlying process. The simulated observations show that the Fe i 525.02 nm line gives no information on the height where reconnection takes place. It can only give clues about the heating in the aftermath of the reconnection. However, the information on the magnetic field vector and velocity at this spatial resolution is extremely valuable because it shows what numerical models miss and how they can be improved.

    The gamma irradiation as treatment for control of the immature stages of fruit flies, C. capitata and A. fraterculus in papaya fruits, cultivar Sunrise Solo is studied. The gamma rays attenuation was observed by one and two papaya fruits placed between source and infested fruit, and this changed the radiation doses required to obtain mortality in eggs and larvae of the Medfly. The efficacy of irradiation was higher when the infested papayas were packed in paper box. The radiation dose determined using the Probit 9 concept, for immature stages mortality of C. capitata was 107,74 Gy and for A. fraterculus was 50,82 Gy. The sterilizing doses for adults of C. capitata and D. fraterculus, irradiated as pupae, was 60 Gy and 40 Gy, respectively. (author)

    Behavioral economic measurement of the relative value of tobacco (Cigarette Purchase Task; CPT) is used to examine individual differences in motivation for tobacco under certain contexts. Smokers with psychopathology, relative to those without, may demonstrate stronger demand for tobacco following a period of smoking deprivation, which could account for disparate rates of smoking and cessation among this subgroup. Participants (n=111) were community-recruited adult daily smokers who completed the CPT after a deprivation period of approximately 60min. Presence of psychopathology was assessed via clinical interview; 40.5% (n=45) of the sample met criteria for past-year psychological diagnosis. Specifically, 31.5% (n=35) had an emotional disorder (anxiety/depressive disorder), 17.1% (n=19) had a substance use disorder, and 19.1% of the sample had more than one disorder. Smokers with any psychopathology showed significantly higher intensity (demand at unrestricted cost; $0) and O max (peak expenditure for a drug) relative to smokers with no psychopathology. Intensity was significantly higher among smokers with an emotional disorder compared to those without. Smokers with a substance use disorder showed significantly higher intensity and O max , and lower elasticity, reflecting greater insensitivity to price increases. Having≥2 disorders was associated with higher intensity relative to having 1 or no disorders. Findings suggest that presence of psychopathology may be associated with greater and more persistent motivation to smoke. Future work is needed to explore the mechanism linking psychopathology to tobacco demand. Copyright © 2017 Elsevier B.V. All rights reserved.

    We study fully developed, steady granular flows confined between parallel flat frictional sidewalls using numerical simulations and experiments. Above a critical rate, sidewall friction stabilizes the underlying heap at an inclination larger than the angle of repose. The shear rate is constant and independent of inclination over much of the flowing layer. In the direction normal to the free surface, the solid volume fraction increases on a scale equal to half the flowing layer depth. Beneath a critical depth at which internal friction is invariant, grains exhibit creeping and intermittent cage motion similar to that in glasses, causing gradual weakening of friction at the walls.

    Many clinical applications have been recommended for glass-cermet cement because of its improved properties compared to the original glass-ionomer cements. It has also been accepted as a dentinal substitute that can strengthen teeth. In this paper, an additional clinical application for glass-cermet cement, the reinforcement of weakened endodontically treated roots, is suggested. This technique is in keeping with the trends of tooth conservation and the use of an adhesive restorative material in the restoration of severely damaged teeth by a conservative approach.

This paper summarizes major constraints associated with a trip to Mars, presents immunological hazards associated with this type of mission, and shows that our current understanding of the immunosuppressive effects of spaceflight is limited. Weakening of the immune system associated with spaceflight is therefore an area that should be considered more thoroughly before we undertake prolonged space voyages.

    Using a first-principles computational tensile test, we show that the ideal tensile strength of an Al grain boundary (GB) is reduced with both Na and Ca GB segregation. We demonstrate that the fracture occurs in the GB interface, dominated by the break of the interfacial bonds. Experimentally, we further show that the presence of Na or Ca impurity, which causes intergranular fracture, reduces the ultimate tensile strength when embrittlement occurs. These results suggest that the Na/Ca-induced intergranular embrittlement of an Al alloy originates mainly from the GB weakening due to the Na/Ca segregation

  16. Plate Like Convection with Viscous Strain Weakening and Corresponding Surface Deformation Pattern

    How plate tectonic surface motions are generated by mantle convection on Earth and possibly other terrestrial type planets has recently become more readily accessible with fully dynamic convection computations. However, it remains debated how plate-like the behavior in such models truly is, and in particular how the well plate boundary dynamics are captured in models which typically exclude the effects of deformation history and memory. Here, we analyze some of the effects of viscous strain weakening on plate behavior and the interactions between interior convection dynamics and surface deformation patterns. We use the finite element code CitcomCU to model convection in a 3D Cartesian model setup. The models are internally heated, with an Arrhenius-type temperature dependent viscosity including plastic yielding and viscous strain weakening (VSW) and healing (VSWH). VSW can mimic first order features of more complex damage mechanisms such as grain-size dependent rheology. Besides plate diagnostic parameters (Plateness, Mobility, and Toroidal: Poloidal ratio) to analyze the tectonic behavior our models, we also explore how "plate boundaries" link to convective patterns. In a first model series, we analyze general surface deformation patterns without VSW. In the early stages, deformation patterns are clearly co-located with up- and downwelling limbs of convection. Along downwellings strain-rates are high and localized, whereas upwellings tend to lead to broad zones of high deformation. At a more advanced stage, however, the plates' interior is highly deformed due to continuous strain accumulation and resurfaced inherited strain. Including only VSW leads to more localized deformation along downwellings. However, at a more advanced stage plate-like convection fails due an overall weakening of the material. This is prevented including strain healing. Deformation pattern at the surface more closely coincide with the internal convection patterns. The average surface

  17. Dynamic weakening of smectite-rich faults at intermediate to high velocities

    Smectite, one of the hydrous clay mineral, is ubiquitous in incoming sediments to subduction zones and is thought to weaken and stabilize subduction thrust faults. However, frictional properties of smectite alone cannot explain the nucleation and propagation of earthquake slip at the shallow plate boundary thrust which potentially causes the devastating tsunamis. Here, we investigate for the first time the effect of smectite fraction in smectite-quartz mixtures on friction at 30 μm/s to 1.3 m/s, to shed a light on the frictional response for the intermediate to high slip rates where the conventional friction experiments have not been explored. In the low slip rate of 30 μm/s, the steady-state coefficient of friction decreases non-linearly increasing smectite fraction: it drops rapidly at moderate fraction of 30-50 vol%. On the other hand, at the faster slip rates of ≥ 150 μm/s the friction lowers from 10-20 vol% fraction since drastic slip weakening appears for the mixtures of ~20 vol % smectite. Hence the fault suddenly loses the strength by adding only 20 % of smectite. The weakening seems to be associated with an excess pore pressure invoked by shear compaction and thermal pressurization during the experiments. This property weakens the fault strength and accelerates the fault slip, even if clay content is small (c.a. 15-35 %), leading to the large stress drop. In contrast, the faults rich in smectite (≥ 50 %) may cause small stress drop during the faulting owing to low friction coefficient of smectite at any slip rates. The results highlight that smectite content significantly affects frictional properties of faults and may generates the diversity in the subduction zone earthquakes.

    2006-01-01

    To examine the salience of tobacco marketing on postsecondary campuses and student support for tobacco control policies. Face-to-face surveys were conducted with 1690 students at 3 universities in southwestern Ontario. Virtually all (97%) students reported noticing tobacco marketing in the past year, and 35% reported noticing marketing on campus. There was strong support for smoke-free restrictions on campus, including restaurants and bars (82%), and for prohibitions on campus marketing. The presence of campus policies was associated with reduced exposure to marketing and increased policy support. There is strong support among students to remove tobacco marketing from campus and to introduce comprehensive smoke-free restrictions.

    Recent studies have described tobacco advertising in the print media, on billboards, and through sponsorship of cultural and sporting events. However, little attention has been given to another common and unavoidable source of tobacco advertising, that which is encountered in retail stores. In July 1987, we conducted a survey of 61 packaged goods retail stores in Buffalo, NY, to assess the prevalence and type of point-of-sale tobacco advertising. In addition, store owners or managers were sur...

    In 2009, the Food and Drug Administration (FDA) banned characterising flavours in cigarettes (except for menthol) due to their appeal to teen starter smokers. In August 2016, the agency deemed all tobacco products to be under its authority and a more comprehensive flavour ban is under consideration. To determine the scope and scale of alcohol-flavoured tobacco products among cigars & cigarillos, hookahs and electronic cigarettes (e-cigarettes). Alcohol-flavoured tobacco products were identified by online search of tobacco purveyors' product lines and via Google search cross-referencing the various tobacco product types versus a list of alcoholic beverage flavours (eg, wine, beer, appletini, margarita). 48 types of alcohol-flavoured tobacco products marketed by 409 tobacco brands were identified. Alcohol flavours included mixed drinks (n=25), spirits (11), liqueurs (7) and wine/beer (5). Sweet and fruity tropical mixed drink flavours were marketed by the most brands: piña colada (96), mojito (66) and margarita (50). Wine flavours were common with 104 brands. Among the tobacco product categories, brands offering alcohol-flavoured e-cigarettes (280) were most numerous, but alcohol-flavoured products were also marketed by cigars & cigarillos (88) and hookah brands (41). Brands by major tobacco companies (eg, Philip Morris, Imperial Tobacco) were well represented among alcohol-flavoured cigars & cigarillos with five companies offering a total of 17 brands. The widespread availability of alcohol-flavoured tobacco products illustrates the need to regulate characterising flavours on all tobacco products. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    School personnel, who are respected members of the community, may exert significant influence on policy adoption. This study assessed the impact of school personnel's permissiveness toward tobacco industry sponsorship activities on their support for complete bans on tobacco advertisements, comprehensive smoke-free laws and increased tobacco prices. Representative data were obtained from the Global School Personnel Survey for 29 African countries (n = 17 929). Adjusted prevalence ratios (aPR) were calculated using multi-variable Poisson regression models to assess the impact of permissiveness toward tobacco sponsorship activities on support for tobacco control policies (p industry should be allowed to sponsor school events were significantly less likely to support complete bans on tobacco advertisements [aPR = 0.89; 95% confidence interval (CI) 0.84-0.95] and comprehensive smoke-free laws (aPR = 0.95; 95% CI 0.92-0.98). In contrast, support for complete tobacco advertisement bans was more likely among those who believed that the tobacco industry encourages youths to smoke (aPR = 1.27; 95% CI 1.17-1.37), and among those who taught about health sometimes (aPR = 1.06; 95% CI 1.01-1.11) or a lot (aPR = 1.05; 95% CI 1.01-1.10) compared with those who did not teach about health at all. These findings underscore the need to educate school personnel on tobacco industry's strategies to undermine tobacco control policies. This may help to build school personnel support for laws intended to reduce youth susceptibility, experimentation and established use of tobacco products. © The Author 2014.

    Non-cigarette tobacco marketing is less regulated and may promote cigarette smoking among adolescents. We quantified receptivity to advertising for multiple tobacco products and hypothesized associations with susceptibility to cigarette smoking. Wave 1 of the nationally representative PATH (Population Assessment of Tobacco and Health) study interviewed 10 751 adolescents who had never used tobacco. A stratified random selection of 5 advertisements for each of cigarettes, e-cigarettes, smokeless products, and cigars were shown from 959 recent tobacco advertisements. Aided recall was classified as low receptivity, and image-liking or favorite ad as higher receptivity. The main dependent variable was susceptibility to cigarette smoking. Among US youth, 41% of 12 to 13 year olds and half of older adolescents were receptive to at least 1 tobacco advertisement. Across each age group, receptivity to advertising was highest for e-cigarettes (28%-33%) followed by cigarettes (22%-25%), smokeless tobacco (15%-21%), and cigars (8%-13%). E-cigarette ads shown on television had the highest recall. Among cigarette-susceptible adolescents, receptivity to e-cigarette advertising (39.7%; 95% confidence interval [CI]: 37.9%-41.6%) was higher than for cigarette advertising (31.7%; 95% CI: 29.9%-33.6%). Receptivity to advertising for each tobacco product was associated with increased susceptibility to cigarette smoking, with no significant difference across products (similar odds for both cigarette and e-cigarette advertising; adjusted odds ratio = 1.22; 95% CI: 1.09-1.37). A large proportion of US adolescent never tobacco users are receptive to tobacco advertising, with television advertising for e-cigarettes having the highest recall. Receptivity to advertising for each non-cigarette tobacco product was associated with susceptibility to smoke cigarettes. Copyright © 2017 by the American Academy of Pediatrics.

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

  8. The Capacity for Compaction Weakening in Fault Gouge in Nature and Experiment

    As faults form in low permeability rocks, the compaction of fault gouge can lead to significant pore-fluid pressure increases. The pore pressure increase results from the collapse of the porosity through shear-enhanced compaction and the low hydraulic diffusivity of the gouge that inhibits fluid flow. In experiments, the frictional properties of clay-bearing fault gouges are significantly affected by the development of locally high pore-fluid pressures when compaction rates are high due to fast displacement rates or slip in underconsolidated materials. We show how the coefficient of friction of fault gouges sheared at different slip velocities can be explained with a numerical model that is constrained by laboratory measurements of contemporaneous changes in permeability and porosity. In nature, for compaction weakening to play an important role in earthquake nucleation (and rupture propagation), a mechanism is required to reset the porosity, i.e., maintain underconsolidated gouge along the fault plane. We use the observations of structures within the principal slip zone of the Alpine Fault in New Zealand to suggest that cyclic fluidization of the gouge occurs during coseismic slip, thereby resetting the gouge porosity prior to the next seismic event. Results from confined laboratory rotary shear measurements at elevated slip rates appear to support the hypothesis that fluidization leads to underconsolidation and, thus, to potential weakening by shear-enhanced compaction-induced pore-fluid pressurization.

    Across four studies, we found evidence for an implicit pro-White leadership bias that helps explain the underrepresentation of ethnic minorities in leadership positions. Both White-majority and ethnic minority participants reacted significantly faster when ethnically White names and leadership roles (e.g., manager; Study 1) or leadership traits (e.g., decisiveness; Study 2 & 3) were paired in an Implicit Association Test (IAT) rather than when ethnic minority names and leadership traits were paired. Moreover, the implicit pro-White leadership bias showed discriminant validity with the conventional implicit bias measures (Study 3). Importantly, results showed that the pro-White leadership bias can be weakened when situational cues increase the salience of a dual identity (Study 4). This, in turn, can diminish the explicit pro-White bias in promotion related decision making processes (Study 4). This research offers a new tool to measure the implicit psychological processes underlying the underrepresentation of ethnic minorities in leadership positions and proposes interventions to weaken such biases.

    Some studies have suggested that the shaking and deformation associated with earthquake would result in a temporary increased hillslope erodibility. However very few data have been able to clarify such effect. We present integrated geomorphic data constraining an elevated landslide rate following 4 continental shallow earthquakes, the Mw 6.9 Finisterre (1993), the Mw 7.6 ChiChi (1999), the Mw 6.6 Niigata (2004) and the Mw 6.8 Iwate-Miyagi (2008) earthquakes. We constrained the magnitude, the recovery time and somewhat the mechanism at the source of this higher landslide risk. We provide some evidences excluding aftershocks or rain forcing intensity as possible mechanism and leaving subsurface weakening as the most likely. The landslide data suggest that this ground strength weakening is not limited to the soil cover but also affect the shallow bedrock. Additionally, we used ambient noise autocorrelation techniques to monitor shallow subsurface seismic velocity within the epicentral area of three of those earthquakes. For most stations we observe a velocity drop followed by a recovery processes of several years in fair agreement with the recovery time estimated based on landslide observation. Thus a common processes could alter the strength of the first 10m of soil/rock and simultaneously drive the landslide rate increase and the seismic velocity drop. The ability to firmly demonstrate this link require additional constraints on the seismic signal interpretation but would provide a very useful tool for post-earthquake risk managment.

  13. Rapid acceleration leads to rapid weakening in earthquake-like laboratory experiments

    2012-12-01

    We simulated the slip of a fault-patch during a large earthquake by rapidly loading an experimental, ring-shaped fault with energy stored in a spinning flywheel. The flywheel abruptly delivers a finite amount of energy by spinning the fault-patch that spontaneously dissipates the energy without operator intervention. We conducted 42 experiments on Sierra White granite (SWG) samples, and 24 experiments on Kasota dolomite (KD) samples. Each experiment starts by spinning a 225 kg disk-shaped flywheel to a prescribed angular velocity. We refer to this experiment as an "earthquake-like slip-event" (ELSE). The strength-evolution in ELSE experiments is similar to the strength-evolution proposed for earthquake models and observed in stick-slip experiments. Further, we found that ELSE experiments are similar to earthquakes in at least three ways: (1) slip driven by the release of a finite amount of stored energy; (2) pattern of fault strength evolution; and (3) seismically observed values, such as average slip, peak-velocity and rise-time. By assuming that the measured slip, D, in ELSE experiments is equivalent to the average slip during an earthquake, we found that ELSE experiments (D = 0.003-4.6 m) correspond to earthquakes in moment-magnitude range of Mw = 4-8. In ELSE experiments, the critical-slip-distance, dc, has mean values of 2.7 cm and 1.2 cm for SWG and KD, that are much shorter than the 1-10 m in steady-state classical experiments in rotary shear systems. We attribute these dc values, to ELSE loading in which the fault-patch is abruptly loaded by impact with a spinning flywheel. Under this loading, the friction-velocity relations are strikingly different from those under steady-state loading on the same rock samples with the same shear system (Reches and Lockner, Nature, 2010). We further note that the slip acceleration in ELSE evolves systematically with fault strength and wear-rate, and that the dynamic weakening is restricted to the period of intense

  15. Hollywood on tobacco: how the entertainment industry understands tobacco portrayal

    Science.gov (United States)

    Shields, D.; Carol, J.; Balbach, E.; McGee, S.

    1999-01-01

    OBJECTIVE—To determine how people in the California-based entertainment industry think about the portrayal of tobacco use in movies and on television. Specifically, to explore who decides when to include tobacco in a project; how that decision is made; what issues are considered; what messages are intended; whether and how the issue of secondhand smoke is considered; and what advocacy methods might be useful in influencing future decisions about tobacco portrayal.
DESIGN—Qualitative in-depth interviews of entertainment industry personnel,with a semi-structured interview protocol to guide the interview.
SUBJECTS—54 subjects drawn from a convenience sample of writers, actors, directors, producers, studio executives, and others involved in the film industry.
RESULTS—Hollywood is heterogeneous with varying perspectives on rates of tobacco use portrayal; intentionality of the decision to use and the necessity to portray tobacco use; and its degree of acceptance of responsibility for influencing societal smoking. Tobacco depiction may originate with the writer, actor, or director and is included most frequently to elucidate character or portray reality. On-camera smoking is influenced by actors' off-camera tobacco use.
CONCLUSIONS—The research presented can help advocates better understand the norms and values of those working within the entertainment industry and thereby assist them in creating more effective change strategies.

    Cigarette butts and other postconsumer products from tobacco use are the most common waste elements picked up worldwide each year during environmental cleanups. Under the environmental principle of Extended Producer Responsibility, tobacco product manufacturers may be held responsible for collection, transport, processing and safe disposal of tobacco product waste (TPW). Legislation has been applied to other toxic and hazardous postconsumer waste products such as paints, pesticide containers and unused pharmaceuticals, to reduce, prevent and mitigate their environmental impacts. Additional product stewardship (PS) requirements may be necessary for other stakeholders and beneficiaries of tobacco product sales and use, especially suppliers, retailers and consumers, in order to ensure effective TPW reduction. This report describes how a Model Tobacco Waste Act may be adopted by national and subnational jurisdictions to address the environmental impacts of TPW. Such a law will also reduce tobacco use and its health consequences by raising attention to the environmental hazards of TPW, increasing the price of tobacco products, and reducing the number of tobacco product retailers.

    The use of the method of advanced shooting on mines of different basins of the country indicated the need to generalize results of work for forced weakening of the roofing on mines in the sector in order to create ''Instructions For Selecting the Methods and Parameters of Forced Weakening of Roofing in the Stoping Faces'' with the participation of the basin scientific research institutes under the leadership of the VNIMI. The main method of weakening which has been introduced in the Karaganda basin is frontal shooting with the use of torpedo-charges. Shooting of the roofing in order reduce the intensity of the primary settling of the main roofing is done in parallel and perpendicular plans. With the parallel plan, the wells are drilled out from the adjoining roadways parallel to the stoping face, and with perpendicular plan, from the assembly chamber perpendicular to the stoping face. In order to reduce the intensity of secondary settling of the main roofing, the parallel or parallel-inclined method is used in designing of the torpedo-charge and the torpedo-head. It is reported that the torpedo-charge is a set of individual torpedos made of polyethylene pipes of length 1500 mm connected to each other with the help of couplings and splints. The torpedo-head consists of a polyethylene pipe of length 700 mm with wall thickness 15-17 mm filled with bulk explosives. Within the torpedo there are 2 explosive charges with electric-detonators for instantaneous action. The main cables of the explosive circuit are connected to the electric detonators and are passed through the packing pipe. In the improved design of the torpedo-head and the torpedo-charge, there are no metal parts. This excludes blow-out of particles of incandescent metal during the explosion and increases the level of work safety. The torpedo-charge is installed manually or mechanically with the help of a metal guide (rammer) which is removed from the well after it delivers the torpedo-charge.

    Water weakening is a well-known phenomenon which can lead to subsidence during the production of hydrocarbon reservoirs. The example of the Ekofisk oil field in the North Sea has been well documented for years. In order to assess water weakening effects in reservoir rocks, previous studies have focused on changes in the failure envelopes derived from mechanical tests conducted on rocks saturated either with water or with inert fluids. However, little attention has been paid so far on the mechanical behaviour during the fluid injection stage, like in enhanced oil recovery operations. We studied the effect of fluid injection on the mechanical behaviour of Sherwood sandstone, a weakly-consolidated sandstone sampled at Ladram Bay in UK. In order to highlight possible weakening effects, water and inert oil have been injected into critically-loaded samples to assess their effect on strength and elastic properties and to derive the acoustic signature of the saturation front for each fluid. The specimens were instrumented with 16 ultrasonic P-wave transducers for both passive and active acoustic monitoring during fluid injection and loading. After conducting standard triaxial tests on three samples saturated with air, water and oil respectively, mechanical creep tests were conducted on dry samples loaded at 80% of the compressive strength of the dry rock. While these conditions are kept constant, a fluid is injected at the bottom end of the sample with a low back pressure (0.5 MPa) to minimize effective stress variations during injection. Both water and oil were used as the injected pore fluid in two experiments. As soon as the fluids start to flow into the samples, creep is taking place with a much higher strain rate for water injection compared to oil injection. A transition from secondary creep to tertiary creep is observed in the water injection test whereas in the oil injection test no significant creep acceleration is observed after one pore volume of oil was

It is therefore a measure of the internal surface friction between solid and fluid which can be interpreted as a friction factor on the pore scale and we propose it can be extrapolated...... using the Biot critical frequency as a single reference. Other viscoplastic parameters were investigated in the same manner to verify the range of the functioning of the friction factor.

It is also inferred that the observed water weakening phenomenon may be attributed to the friction between solid and fluid....

    In the presence of quantum-gravity fluctuations (space-time foam), the CPT operator may be ill-defined. Its perturbative treatment leads to a modification of the Einstein-Podolsky-Rosen correlation of the neutral meson system by adding an entanglement-weakening term of the wrong exchange symmetry, the ω-effect. In the current paper we identify how to probe the complex ω in the entangled B{sub d}-system using the flavour (f)-CP(g) eigenstate decay channels: the connection between the intensities for the two time-ordered decays (f, g) and (g, f) is lost. Appropriate observables are constructed allowing independent experimental determinations of Re(ω) and Im(ω), disentangled from CPT violation in the evolution Hamiltonian Re(θ) and Im(θ). 2σ tensions for both Re(θ) and Im(ω) are shown to be uncorrelated.

    In order to be able to carry out a videodensitometry simultaneously with the cineangiocardiography with pulsed X-rays, the weakening of the X-radiation by contrast media is more closely examined and a calibration of the amplitudes is carried out. The determination of the extinction curves for different parts of the X-ray pulses show that under unfavourable conditions (high voltage, low tube current, no Cu filtration) the spectrum is displaced to larger wavelengths, white an influence on the weakness coefficient only occurs after the intensity has fallen to 10% of the impulse maximum. On the other hand, the quantity depedence of the extinction coefficient is significant. The densitometry simulations performed with a digital computer using empirically gained calibration curves show that a quantitative densitometry is possible even if the Lambert-Beer law is not valid.

    A new flux-weakening control strategy for permanent magnet contactors is proposed. By matching the dynamic attraction force and the antiforce, the terminal velocity and collision energy of the movable iron in the closing process are significantly reduced. The movable iron displacement is estimated by detecting the closing voltage and current with the proposed control. A dynamic mathematical model is also established under four kinds of excitation scenarios. The attraction force and flux linkage are predicted by finite element method and the dynamics of the closing process is simulated using the 4th-order Runge-Kutta algorithm. Experiments are carried out on a 250A prototype with an intelligent control unit to verify the proposed control strategy.

  8. Weakening of flux-pinning strength for high-Tc superconductors in an alternating magnetic field

    1992-01-01

    This paper reports on the flux-pinning forces in high temperature superconductors which were found to be weakened in an ac field as the applied field strength or the frequency increases. In the weakly pinned regime, flux dynamics could be described with the concept of magnetic diffusion. Flux-motion-induced finite resistivity could lead to significant skin-effect which was reflected in the ac screening effectiveness. The frequency dependence of the relative local field within a superconducting hollow cylinder were used to deduce the flux-motion resistivity ρ. For superconducting YB 2 Cu 3 O 7 - x compounds at 77K it was found that ρ ∼(mu, Omega)-cm. The corresponding magnetic diffusion coefficient was ∼ 224 cm 2 /s. At 750 Hz the skin depth is around 1.54 mm as compared with the 2-mm sample wall thickness

    Full Text Available This was a qualitative study with the purpose of designing a meta-model for the work process of the Family Health Strategy (FHS team. It was based on the experience of six sample groups, composed of their members (physicians, professional nurses, dentists, dental assistants, licensed technical nurses and community health agents in a city in São Paulo state, Brazil, totaling 54 subjects. Six theoretical models emerged from non-directive interviews. These were analyzed according to Grounded Theory and submitted to the meta-synthesis strategy, which produced the meta-model "between the processes of strengthening and weakening of the FHS model: professional-team-community reciprocity as an intervening component". When analyzed in light of the Theory of Complexity (TC, it showed to be a work with a vertical and authoritarian tendency, which is largely hegemonic in the tradition of public health care policies.

  11. Weakening of the radioprotective action of gas hypoxia with growth of ascitic tumors

    1975-06-27

    It was shown previously that moderate hypoxia induced by breathing oxygen-poor air (5 percent O/sub 2/) reduces the lethal effect of the total irradiation of mice, while with local irradiation of tumors reduction of tumor growth rate is even more marked in hypoxia-protected animals than with irradiation of mice in normal air. This suggests the possible therapeutic application of hypoxia. It was found that acute gas hypoxia strongly retards radiation damage to bone marrow, both qualitatively (type of cells affected) and quantitatively. In addition, a definite weakening of the protective effect of hypoxia was observed, this being proportional to increase in tumor size. Planned future tests involving direct dynamic measurement of oxygen stress as a function of amount of ascites are expected to supply further information on reduction of radiosensitivity of normal tissues and on the selective intensification of tumor regression. Graphic data accompany the paper. (JPRS)

  12. Rapid acceleration leads to rapid weakening in earthquake-like laboratory experiments

    Science.gov (United States)

    Chang, Jefferson C.; Lockner, David A.; Reches, Z.

    2012-01-01

    After nucleation, a large earthquake propagates as an expanding rupture front along a fault. This front activates countless fault patches that slip by consuming energy stored in Earth’s crust. We simulated the slip of a fault patch by rapidly loading an experimental fault with energy stored in a spinning flywheel. The spontaneous evolution of strength, acceleration, and velocity indicates that our experiments are proxies of fault-patch behavior during earthquakes of moment magnitude (Mw) = 4 to 8. We show that seismically determined earthquake parameters (e.g., displacement, velocity, magnitude, or fracture energy) can be used to estimate the intensity of the energy release during an earthquake. Our experiments further indicate that high acceleration imposed by the earthquake’s rupture front quickens dynamic weakening by intense wear of the fault zone.

  13. The transition of dynamic rupture styles in elastic media under velocity-weakening friction

    2012-01-01

    Although kinematic earthquake source inversions show dominantly pulse-like subshear rupture behavior, seismological observations, laboratory experiments and theoretical models indicate that earthquakes can operate with different rupture styles: either as pulses or cracks, that propagate at subshear or supershear speeds. The determination of rupture style and speed has important implications for ground motions and may inform about the state of stress and strength of active fault zones. We conduct 2D in-plane dynamic rupture simulations with a spectral element method to investigate the diversity of rupture styles on faults governed by velocity-and-state-dependent friction with dramatic velocity-weakening at high slip rate. Our rupture models are governed by uniform initial stresses, and are artificially initiated. We identify the conditions that lead to different rupture styles by investigating the transitions between decaying, steady state and growing pulses, cracks, sub-shear and super-shear ruptures as a function of background stress, nucleation size and characteristic velocity at the onset of severe weakening. Our models show that small changes of background stress or nucleation size may lead to dramatic changes of rupture style. We characterize the asymptotic properties of steady state and self-similar pulses as a function of background stress. We show that an earthquake may not be restricted to a single rupture style, but that complex rupture patterns may emerge that consist of multiple rupture fronts, possibly involving different styles and back-propagating fronts. We also demonstrate the possibility of a super-shear transition for pulse-like ruptures. Finally, we draw connections between our findings and recent seismological observations.

    To highlight revelations from internal tobacco industry documents about the conduct of the industry in the Philippines since the 1960s. Areas explored include political corruption, health, employment of consultants, resisting pack labelling, and marketing and advertising. Systematic keyword Minnesota depository website searches of tobacco industry internal documents made available through the Master Settlement Agreement. The Philippines has long suffered a reputation for political corruption where collusion between state and business was based on the exchange of political donations for favourable economic policies. The tobacco industry was able to limit the effectiveness of proposed anti-tobacco legislation. A prominent scientist publicly repudiated links between active and passive smoking and disease. The placement of health warning labels was negotiated to benefit the industry, and the commercial environment allowed it to capitalise on their marketing freedoms to the fullest potential. Women, children, youth, and the poor have been targeted. The politically laissez faire Philippines presented tobacco companies with an environment ripe for exploitation. The Philippines has seen some of the world's most extreme and controversial forms of tobacco promotion flourish. Against international standards of progress, the Philippines is among the world's slowest nations to take tobacco control seriously.

    While fruit, candy and alcohol characterising flavours are not allowed in cigarettes in the USA, other flavoured tobacco products such as smokeless tobacco (ST) continue to be sold. We investigated tobacco manufacturers' use of flavoured additives in ST products, the target audience(s) for flavoured products, and marketing strategies promoting products by emphasising their flavour. Qualitative analysis of internal tobacco industry documents triangulated with data from national newspaper articles, trade press and internet. Internally, flavoured products have been consistently associated with young and inexperienced tobacco users. Internal studies confirmed that candy-like sweeter milder flavours (eg, mint, fruit) could increase appeal to starters by evoking a perception of mildness, blinding the strong tobacco taste and unpleasant mouth feel; or by modifying nicotine delivery by affecting product pH. Similar to cigarettes, flavoured ST is likely to encourage novices to start using tobacco, and regulations limiting or eliminating flavours in cigarettes should be extended to include flavoured ST products.

    Full Text Available O mamão é um fruto de grande importância econômica, social e nutricional. No entanto, apresenta conservação limitada devido à deterioração pós-colheita e ao rápido amadurecimento. Portanto, o objetivo deste trabalho foi utilizar soluções de quitosana associadas ao glicerol como recobrimento de mamão papaia da cultivar 'Sunrise Solo' para manter a qualidade pós-colheita e prolongar sua vida útil. Os frutos foram lavados em água potável, higienizados em solução de hipoclorito de sódio a 200 mg L-1 por 10 minutos e secos à temperatura ambiente. Os tratamentos consistiram na imersão ou não (controle dos frutos em cinco concentrações (0,25%; 0,50%; 0,75%; 1,0% e 1,25% de quitosana. Decorrida a secagem natural do revestimento, os frutos foram armazenados a 28 ± 3 ºC e 65-70% UR. Foi utilizado um delineamento inteiramente casualisado, utilizando-se de seis concentrações de quitosana com oito repetições, totalizando 48 frutos. Ao atingir o ponto ótimo para o consumo, avaliaram-se o teor de ácido ascórbico, de sólidos solúveis, da acidez titulável, da firmeza, a perda de massa fresca, o desenvolvimento fúngico e a vida útil. A aplicação de quitosana em mamão 'Sunrise Solo' manteve a firmeza e os teores de sólidos solúveis, de acidez titulável e de ácido ascórbico dos frutos até o ponto considerado ótimo para o consumo, em termos de aparência. A concentração de 1% de quitosana manteve a qualidade e aumentou a vida útil dos frutos em quatro dias. A quitosana inibiu o crescimento de fungos dos gêneros Cladosporium, Aspergillus e Penicillium.

    2012-05-01

    Indonesia is the world's fifth largest cigarette market in the world but for decades, transnational tobacco companies (TTCs) have had limited success infiltrating this market, due to their inability to compete in the kretek market. Kreteks are clove/tobacco cigarettes that most Indonesians smoke. To determine how Phillip Morris International (PMI) and British American Tobacco (BAT) have now successfully achieved a substantial market presence in Indonesia. We analyzed previously secret, tobacco industry documents, corporate reports on Indonesia operations, the Tobacco Trade press, Indonesia media, and "The Roadmap". Internal, corporate documents from BAT and PMI demonstrate that they had known for decades that kreteks are highly carcinogenic. Despite that knowledge, BAT and PMI now own and heavily market these products, as well as new more westernised versions of kreteks. BAT and PMI used their successful basic strategy of keeping cigarettes affordable by maintaining the social responsibility of smoking and opposing smoke-free workplace laws but in the 21st century, they added the acquisition of and westernisation of domestic kretek manufacturers as an additional strategy. These acquisitions allowed them to assert influences on health policy in Indonesia and to grow their business under current government policy embodied in the 2007-2020 Roadmap of Tobacco Products Industry and Excise Policy which calls for increased cigarette production by 12% over the next 15 years. PMI and Bat have successfully entered and are expanding their share in the Indonesia cigarette market. Despite the obvious and pervasive influence of the tobacco industry on policy decisions, the Indonesian government should ratify the FCTC and implement effective legislation to reduce tobacco consumption and exposure to tobacco smoke and revise the Roadmap to protect future generations of Indonesians.

    The tobacco industry increasingly invests in point-of-sale (POS) marketing. In July 2012, New Zealand required the removal of POS tobacco displays concurrently with increased enforcement and penalties for selling tobacco to minors, and additional restrictions on tobacco sponsorship. We evaluated the impact of these measures using a before-after study. We analysed data from annual surveys of more than 25 000 year 10 (14-15 years) students from 2007 and 2011 to 2014. Measures included prevalence of smoking-related behaviours and strength of association between visiting tobacco-retailing stores and smoking behaviours. Between 2011 and 2014, smoking experimentation (had smoked ever but smoked less than monthly currently) decreased from 23% in 2011 to 17% in 2014 (adjusted odds ratio (aOR) 0.73, 95% CI 0.69 to 0.78); current smoking (at least monthly) prevalence from 9% to 7% (aOR 0.71, 0.64 to 0.79) and initiation in the last year from 13% to 11% (aOR 0.91, 0.84 to 0.98). Attempted purchase of cigarettes in the past 30 days among smokers decreased from 30% in 2012 to 26% in 2013 (aOR 0.77, 0.63 to 0.91). Positive associations between frequency of visiting tobacco-retailing stores and smoking-related behaviours weakened post-implementation. The introduction of a POS display ban and concurrent measures was followed by significant reductions in initiation, experimental and regular smoking, attempted purchase of cigarettes, and reduced association between visiting tobacco-retailing stores and smoking behaviours. The findings suggest that POS display bans are important components of strategies to reduce smoking initiation among youth and young people. Published by the BMJ Publishing Group Limited.

    2010-07-01

    Tobacco is a well-acknowledged social and health evil. The history of tobacco use traces back to the dawn of human civilization and has been deeply entrenched into the human society since time immemorial. The social, economic, and health impact of tobacco has been a subject of intense debate over the recent decades. For India, this problem has been a unique one, with the consumption patterns either largely influenced by the socioeconomic backgrounds or dictated by the cultural diversity. With more than 200 million tobacco consumers in the country at present, it becomes imperative to address this health hazard and stir up strong measures toward damage control. This article addresses the tobacco problem, its evolution, and the factors that have affected the growth of Indian tobacco industry. It also highlights the current legislative measures against tobacco, fiscal gains to the government, and the serious health and economic impact to the consumer, compounded by the increasing cost of private health care in the present era of consumerism.

    2009-01-01

    The cigarette companies and their lobbying organization used tobacco industry-produced films and videos about tobacco farming to support their political, public relations, and public policy goals. Critical discourse analysis shows how tobacco companies utilized film and video imagery and narratives of tobacco farmers and tobacco economies for lobbying politicians and influencing consumers, industry-allied groups, and retail shop owners to oppose tobacco control measures and counter publicity on the health hazards, social problems, and environmental effects of tobacco growing. Imagery and narratives of tobacco farmers, tobacco barns, and agricultural landscapes in industry videos constituted a tobacco industry strategy to construct a corporate vision of tobacco farm culture that privileges the economic benefits of tobacco. The positive discursive representations of tobacco farming ignored actual behavior of tobacco companies to promote relationships of dependency and subordination for tobacco farmers and to contribute to tobacco-related poverty, child labor, and deforestation in tobacco growing countries. While showing tobacco farming as a family and a national tradition and a source of jobs, tobacco companies portrayed tobacco as a tradition to be protected instead of an industry to be regulated and denormalized.

  7. The evolution of health warning labels on cigarette packs: the role of precedents, and tobacco industry strategies to block diffusion

    2013-01-01

    Objective To analyse the evolution and diffusion of health warnings on cigarette packs around the world, including tobacco industry attempts to block this diffusion. Methods We analysed tobacco industry documents and public sources to construct a database on the global evolution and diffusion of health warning labels from 1966 to 2012, and also analysed industry strategies. Results Health warning labels, especially labels with graphic elements, threaten the tobacco industry because they are a low-cost, effective measure to reduce smoking. Multinational tobacco companies did not object to voluntary innocuous warnings with ambiguous health messages, in part because they saw them as offering protection from lawsuits and local packaging regulations. The companies worked systematically at the international level to block or weaken warnings once stronger more specific warnings began to appear in the 1970s. Since 1985 in Iceland, the tobacco industry has been aware of the effectiveness of graphic health warning labels (GWHL). The industry launched an all-out attack in the early 1990s to prevent GHWLs, and was successful in delaying GHWLs internationally for nearly 10 years. Conclusions Beginning in 2005, as a result of the World Health Organisation Framework Convention on Tobacco Control (FCTC), GHWLs began to spread. Effective implementation of FCTC labelling provisions has stimulated diffusion of strong health warning labels despite industry opposition. PMID:23092884

    Physics-based numerical simulations of earthquakes and slow slip, coupled with field observations and laboratory experiments, can, in principle, be used to determine fault properties and potential fault behaviors. Because of the computational cost of simulating inertial wave-mediated effects, their representation is often simplified. The quasi-dynamic (QD) approach approximately accounts for inertial effects through a radiation damping term. We compare QD and fully dynamic (FD) simulations by exploring the long-term behavior of rate-and-state fault models with and without additional weakening during seismic slip. The models incorporate a velocity-strengthening (VS) patch in a velocity-weakening (VW) zone, to consider rupture interaction with a slip-inhibiting heterogeneity. Without additional weakening, the QD and FD approaches generate qualitatively similar slip patterns with quantitative differences, such as slower slip velocities and rupture speeds during earthquakes and more propensity for rupture arrest at the VS patch in the QD cases. Simulations with additional coseismic weakening produce qualitatively different patterns of earthquakes, with near-periodic pulse-like events in the FD simulations and much larger crack-like events accompanied by smaller events in the QD simulations. This is because the FD simulations with additional weakening allow earthquake rupture to propagate at a much lower level of prestress than the QD simulations. The resulting much larger ruptures in the QD simulations are more likely to propagate through the VS patch, unlike for the cases with no additional weakening. Overall, the QD approach should be used with caution, as the QD simulation results could drastically differ from the true response of the physical model considered.

  9. Metasomatism and the Weakening of Cratons: A Mechanism to Rift Cratons

    The preservation of cratons is a demonstration of their strength and resistance to deformation. However, several cratons are rifting now (e.g. Tanzania and North China Craton) or have rifted in the past (e.g. North Atlantic Craton). To explain this paradox, we suggest that widespread metasomatism of the originally cold depleted dehydrated craton mantle lithosphere root can act as a potential weakening mechanism. This process, particularly melt metasomatism, increases root density through a melt-peridotite reaction, and reduces root viscosity by increasing the temperature and rehydrating the cratonic mantle lithosphere. Using 2D numerical models, we model silicate-melt metasomatism and rehydration of cold cratonic mantle lithosphere that is positioned beside standard Phanerozoic lithosphere. The models are designed to investigate when a craton is sufficiently weakened to undergo rifting and is no longer protected by the initially weaker adjacent standard Phanerozoic lithosphere. Melt is added to specified layers in the cratonic mantle lithosphere at a uniform volumetric rate determined by the duration of metasomatism (3 Myr, 10 Myr or 30 Myr), until a total of ~30% by volume of melt has been added. During melt addition heat and mass are properly conserved and the density and volume increase by the respective amounts required by the reaction with the peridotite. No extensional boundary conditions are applied to the models during the metasomatism process. As expected, significant refertilization leads to removal and thinning of progressively more gravitationally unstable cratonic mantle lithosphere. We show that the duration of metasomatism dictates the final temperature in the cratonic upper mantle lithosphere. Consequently, when extensional boundary conditions are applied in our rifting tests in most cases the Phanerozoic lithosphere rifts. The craton rifts only in the models with the hottest cratonic upper mantle lithosphere. Our results indicate rifting of cratons

    To estimate the size of illegal tobacco trade and consumption and assess the impact of tobacco tax on the illicit tobacco market in New Zealand (NZ). Data on the import and seizure of legal and illegal tobacco in NZ was obtained from NZ Customs. Previous literature was used to calculate interception rates of illegal tobacco being smuggled and grown in NZ. Annual tobacco returns figures, obtained via the NZ Ministry of Health, were analysed to assess the market dynamics of legal tobacco products. This study found that illicit tobacco constituted 1.8-3.9% of total national tobacco consumption in NZ in 2013. This represents a minor increase compared to previous estimates from 2007-09, suggesting that tax increases enacted by the NZ Government since 2010 have had a minimal impact on encouraging the use and procurement of illicit tobacco. The results highlight a slight rise in small-scale tobacco smuggling through ports and mail centres. However, tobacco returns figures show that current tobacco tax policy has forced manufacturers to focus on the production of cheap legal tobacco products, directly competing with and undercutting the demand for illicit tobacco products. At the same time, locally grown illicit tobacco continues to remain a small, isolated problem and, with recent cuts in duty free tobacco allowance, it is expected that overall illicit tobacco will remain a very small proportion of total tobacco consumption in NZ. © 2015 Public Health Association of Australia.

    Ongoing spring warming allows the growing season to begin earlier, enhancing carbon uptake in northern ecosystems. We use 34 years of atmospheric CO2 concentration measurements at Barrow, Alaska (BRW, 71° N) to show that the interannual relationship between spring temperature and carbon uptake has recently shifted. Here, we use two indicators: the spring zero-crossing date of atmospheric CO2 (SZC) and the magnitude of CO2 drawdown between May and June (SCC). The previously reported strong correlation between SZC, SCC and spring land temperature (ST) was found in the first 17 years of measurements, but disappeared in the last 17 years. As a result, the sensitivity of both SZC and SCC to warming decreased. Simulations with an atmospheric transport model coupled to a terrestrial ecosystem model suggest that the weakened interannual correlation of SZC and SCC with ST in the last 17 years is attributable to the declining temperature response of spring net primary productivity (NPP) rather than to changes in heterotrophic respiration or in atmospheric transport patterns. Reduced chilling during dormancy and emerging light limitation are possible mechanisms that may have contributed to the loss of NPP response to ST. These results thus challenge the ‘warmer spring–bigger sink’ mechanism.

    The growth/climate relationship of theoretically temperature-controlled high-elevation forests has been demonstrated to weaken over recent decades. This is likely due to new tree growth limiting factors, such as an increasing drought risk for ecosystem functioning and productivity across the Mediterranean Basin. In addition, declining tree growth sensitivity to spring temperature may emerge in response to increasing drought stress. Here, we evaluate these ideas by assessing the growth/climate sensitivity of 1500 tree-ring width (TRW) and 102 maximum density (MXD) measurement series from 711 and 74 Pinus uncinata trees, respectively, sampled at 28 high-elevation forest sites across the Pyrenees and two relict populations of the Iberian System. Different dendroclimatological standardization and split period approaches were used to assess the high- to low-frequency behavior of 20th century tree growth in response to temperature means, precipitation totals and drought indices. Long-term variations in TRW track summer temperatures until about 1970 but diverge afterwards, whereas MXD captures the recent temperature increase in the low-frequency domain fairly well. On the other hand summer drought has increasingly driven TRW along the 20th century. Our results suggest fading temperature sensitivity of Iberian high-elevation P. uncinata forest growth, and reveal the importance of summer drought that is becoming the emergent limiting factor of tree ring width formation in many parts of the Mediterranean Basin.

    We explore general scalar-tensor models in the presence of a kinetic mixing between matter and the scalar field, which we call Kinetic Matter Mixing. In the frame where gravity is de-mixed from the scalar this is due to disformal couplings of matter species to the gravitational sector, with disformal coefficients that depend on the gradient of the scalar field. In the frame where matter is minimally coupled, it originates from the so-called beyond Horndeski quadratic Lagrangian. We extend the Effective Theory of Interacting Dark Energy by allowing disformal coupling coefficients to depend on the gradient of the scalar field as well. In this very general approach, we derive the conditions to avoid ghost and gradient instabilities and we define Kinetic Matter Mixing independently of the frame metric used to described the action. We study its phenomenological consequences for a ΛCDM background evolution, first analytically on small scales. Then, we compute the matter power spectrum and the angular spectra of the CMB anisotropies and the CMB lensing potential, on all scales. We employ the public version of COOP, a numerical Einstein-Boltzmann solver that implements very general scalar-tensor modifications of gravity. Rather uniquely, Kinetic Matter Mixing weakens gravity on short scales, predicting a lower σ{sub 8} with respect to the ΛCDM case. We propose this as a possible solution to the tension between the CMB best-fit model and low-redshift observables.

  20. Lateral extrusion of a thermally weakened pluton overburden (Campiglia Marittima, Tuscany)

    The ascent and emplacement of magmas in the upper crust modify the local pre-existing thermal and rheological settings. Such changes have important effects in producing anomalous structures, mass extrusion, rock fracturing, and in some conditions, hydrothermal mineralizations. In the Campiglia Marittima area, detailed field mapping led to the reconstruction of a local deformation history that overlaps, chronologically and spatially, with regional extension. This local deformation was triggered at the Miocene-Pliocene boundary by the intrusion of a monzogranitic pluton beneath a carbonate sedimentary sequence. The emplacement of the pluton produced a perturbation in the rheological behaviour of the carbonate host rocks, producing transient ductile conditions in the very shallow crust. The carbonate rocks were thermally weakened and flowed laterally, accumulating downslope of the pluton roof, mainly toward the east. As the thermal anomaly was decaying, the brittle-ductile boundary moved progressively back towards the pluton, and large tension gash-shaped volumes of fractured marble were generated. These fractured volumes were exploited by rising hydrothermal fluids generating sigmoidal skarn bodies and ore shoots. This work presents the Campiglia Marittima case study as a prime example of structural interference between regional extensional structures and local, lateral mass extrusion in a transient ductile rheological regime triggered by pluton emplacement.

  1. Strain-weakening rheology of marine sponges and its evolutionary implication

    Science.gov (United States)

    Kraus, Emily; Janmey, Paul; Sweeney, Alison; van Oosten, Anne

    Animal cells respond to mechanical stimuli as sensitively as they do to chemical stimuli. Further, cell proliferation is dependent on the viscoelasticity of the polymeric extracellular matrix (ECM) in which they are embedded. Biophysicists are therefore motivated to understand the biomechanics of the ECM itself. To date, this work has focused on the more familiar Bilateria, animals, including humans, with bilateral symmetry. The ECM of this group of animals is now understood to exhibit non-linear rheology that is typically strain- and compression-stiffening, and shear moduli that are frequency-dependent. These complex properties have been attributed to the semi-flexible nature of the underlying polymers. In contrast, we show that marine sponges are markedly strain-weakening under physiologically relevant conditions. Since sponges are a much earlier evolutionary branch than Bilateria, we interrogate the evolutionary potential and biochemical underpinnings of this novel complex rheology in filamentous networks, and cells ability to respond. Further, their life history strategy is uniquely dependent on flow and correlated shear stress, making them a model organism to study self-assembly algorithms organized around flow.

    Full Text Available An electric propulsion system is generally based on torque controlled electric drive and DC series motors are traditionally used for propulsion system. Induction machines, which are reliable, low cost and have less maintenance, satisfy the characteristics of the propulsion and reinstating the DC series motor. Field oriented control (FOC of induction machines can decouple its torque control from field control which allows the induction motor to act like a separately excited DC motor. In this paper, the characteristic control of induction motor is achieved through appropriate design modification of induction motor by varying magnetizing current to produce maximum torque in field weakening (FW region. Thus to improve the torque capability of induction machine in FW region by varying machine parameters. The sensorless operation of the induction motor is carried out by adopting model reference adaptive system (MRAS using sliding mode control (SMC and a FW algorithm based on the voltage and current constraints. The simulation of the induction motor drive models based on the design options have been carried out and analyzed the simulation results.

    Discusses the use of magnetic defectoscopes and defectographs in the nondestructive testing of wire ropes. Emphasizes the need for laboratory pre-calibration where quantitave results are required. Individual system calibration is recommended where instruments with a 95% confidence level in reading are used, e.g. MD-8 defectograph and DLS unit, but improved tolerances achieved in sensor head manufacture have made possible a universal calibration characteristic for use with defectoscopes and a wide variety of heads. A chart is given covering all heads and induction sensors available in Poland. Describes methods of interpreting presented results to indicate degree of wear due to fatigue, abrasion and corrosion in ropes with constituent wires of differing profile. States that the form of rope wear can be deduced from the character of the defectograph pulse readings. Formulae relating the degree of rope weakening to these readings and also to the integrated output are given. Briefly describes a method for determining the loss of rope cross sectional area based on Hall effect chart records. Outlines the use of the MD-9 and MD-10 defectoscopes in assessing rope wear in discrete ranges. Suggests that regular measurements permit an accurate determination of the character of progressive wear and further that pulse analysis of MD-10 results can permit a quantitative determination of wear. 4 refs.

    Full Text Available We investigated the influence of negative emotion on the degree of self-reference effect using event-related potentials (ERPs. We presented emotional pictures and self-referential stimuli (stimuli that accelerate and improve processing and improve memory of information related to an individual’s self-concept in sequence. Participants judged the color of the target stimulus (self-referential stimuli. ERP results showed that the target stimuli elicited larger P2 amplitudes under neutral conditions than under negative emotional conditions. Under neutral conditions, N2 amplitudes for highly self-relevant names (target stimulus were smaller than those for any other names. Under negative emotional conditions, highly and moderately self-referential stimuli activated smaller N2 amplitudes. P3 amplitudes activated by self-referential processing under negative emotional conditions were smaller than neutral conditions. In the left and central sites, highly self-relevant names activated larger P3 amplitudes than any other names. But in the central sites, moderately self-relevant names activated larger P3 amplitudes than non-self-relevant names. The findings indicate that negative emotional processing could weaken the degree of self-reference effect.

    Full Text Available OBJECTIVE: This study evaluated, in vitro, the fracture resistance of human non-vital teeth restored with different reconstruction protocols. MATERIAL AND METHODS: Forty human anterior roots of similar shape and dimensions were assigned to four groups (n=10, according to the root reconstruction protocol: Group I (control: non-weakened roots with glass fiber post; Group II: roots with composite resin by incremental technique and glass fiber post; Group III: roots with accessory glass fiber posts and glass fiber post; and Group IV: roots with anatomic glass fiber post technique. Following post cementation and core reconstruction, the roots were embedded in chemically activated acrylic resin and submitted to fracture resistance testing, with a compressive load at an angle of 45º in relation to the long axis of the root at a speed of 0.5 mm/min until fracture. All data were statistically analyzed with bilateral Dunnett's test (α=0.05. RESULTS: Group I presented higher mean values of fracture resistance when compared with the three experimental groups, which, in turn, presented similar resistance to fracture among each other. None of the techniques of root reconstruction with intraradicular posts improved root strength, and the incremental technique was suggested as being the most recommendable, since the type of fracture that occurred allowed the remaining dental structure to be repaired. CONCLUSION: The results of this in vitro study suggest that the healthy remaining radicular dentin is more important to increase fracture resistance than the root reconstruction protocol.

    High Intensity Focused Ultrasound (HIFU) can be used for the localized heating of biological tissue through the conversion of sound waves into heat. Although originally developed for human medicine, HIFU may also be used to weaken the attachment of pin bones in fish fillets to enable easier removal of such bones. This was shown in the present study, where a series of experiments were performed on HIFU phantoms and fillets of cod and salmon. In thin objects such as fish fillets, the heat is mainly dissipated at the surfaces. However, bones inside the fillet absorb ultrasound energy more efficiently than the surrounding tissue, resulting in a "self-focusing" heating of the bones. Salmon skin was found to effectively block the ultrasound, resulting in a significantly lower heating effect in fillets with skin. Cod skin partly blocked the ultrasound, but only to a small degree, enabling HIFU treatment through the skin. The treatment of fillets to reduce the pin bone attachment yielded an average reduction in the required pulling force by 50% in cod fillets with skin, with little muscle denaturation, and 72% in skinned fillets, with significant muscle denaturation. Salmon fillets were treated from the muscle side of the fillet to circumvent the need for penetration through skin. The treatment resulted in a 30% reduction in the peak pulling force and 10% reduction in the total pulling work, with a slight denaturation of the fillet surface.

    Mutualistic interactions are often subject to exploitation by species that are not directly involved in the mutualism. Understanding which organisms act as such 'third-party' species and how they do so is a major challenge in the current study of mutualistic interactions. Here, we show that even species that appear ecologically similar can have contrasting effects as third-party species. We experimentally compared the effects of nectar-inhabiting bacteria and yeasts on the strength of a mutualism between a hummingbird-pollinated shrub, Mimulus aurantiacus, and its pollinators. We found that the common bacterium Gluconobacter sp., but not the common yeast Metschnikowia reukaufii, reduced pollination success, seed set and nectar consumption by pollinators, thereby weakening the plant-pollinator mutualism. We also found that the bacteria reduced nectar pH and total sugar concentration more greatly than the yeasts did and that the bacteria decreased glucose concentration and increased fructose concentration whereas the yeasts affected neither. These distinct changes to nectar chemistry may underlie the microbes' contrasting effects on the mutualism. Our results suggest that it is necessary to understand the determinants of microbial species composition in nectar and their differential modification of floral rewards to explain the mutual benefits that plants and pollinators gain from each other.

  9. The Weakening of Kin Ties: Exploring the Need for Life-World Led Interventions.

    The protective features that families and wider social relationships can have are required to meet the demands of life in contemporary Western societies. Choice and detraditionalization, however; impede this source of solidarity. Family Group Conferencing (FGC) and other life-world led interventions have the potential to strengthen primary groups. This paper explores the need for such a social intervention, using insights from sociological and philosophical theories and empirical findings from a case study of the research project 'FGC in mental health'. This need is understandable considering the weakening of kin ties, the poor qualities of state agencies to mobilise self-care and informal care, its capacity to produce a shift of power from public to private spheres and its capacity to mitigate the co-isolation of individuals, families and communities. A life-world led intervention like FGC with a specific and modest ambition contributes to small-scale solidarity. This ambition is not inclined to establish a broad social cohesion within society but to restore; in terms of the German philosopher Peter Sloterdijk; immunity (protection) and solidarity in primary groups, and consequently, resolve issues with those (family, neighbours, colleagues) who share a sphere (a situation, a process, a fate).

  10. Priority effects are weakened by a short, but not long, history of sympatric evolution.

    2018-01-31

    Priority effects, or the effects of species arrival history on local species abundances, have been documented in a range of taxa. However, factors determining the extent to which priority effects affect community assembly remain unclear. Using laboratory populations of the bacterium Pseudomonas fluorescens , we examined whether shared evolutionary history affected the strength of priority effects. We hypothesized that sympatric evolution of populations belonging to the same guild would lead to niche differentiation, resulting in phenotypic complementarity that weakens priority effects. Consistent with this hypothesis, we found that priority effects tended to be weaker in sympatrically evolved pairs of immigrating populations than in allopatrically evolved pairs. Furthermore, priority effects were weaker under higher phenotypic complementarity. However, these patterns were observed only in populations with a relatively short history of sympatric evolution, and disappeared when populations had evolved together for a long time. Together, our results suggest that the evolutionary history of organismal traits may dictate the strength of priority effects and, consequently, the extent of historical contingency in the assembly of ecological communities. © 2018 The Author(s).

  11. Investigation of mechanical field weakening of axial flux permanent magnet motor

    2015-12-01

    An investigation of axial flux permanent magnet motor (AFPM) characteristics was conducted with a proposed mechanical field weakening control mechanisms (by means of stator-rotor force manipulation) on the motor through modeling and experimentation. By varying the air gap between at least two bistable positions, the peak torque and top speed of the motor can be extended. The motor high efficiency region can also be extended to cover greater part of the motor operating points. An analytical model of the motor had been developed to study the correlation between the total attraction force (between the rotor and the stator) and the operating parameters of the motor. The test results shows that the motor output complies with the prediction of the research hypothesis and it is likely that a spring locking mechanism can be built to dynamically adjust the air gap of the motor to increase the operating range and could be applied in electric drivetrain applications to improve overall efficiency of electric and hybrid electric vehicles.

  12. ON THE WEAKENING OF THE POLAR MAGNETIC FIELDS DURING SOLAR CYCLE 23

    2009-01-01

    The Sun's polar fields are currently ∼40% weaker than they were during the previous three sunspot minima. This weakening has been accompanied by a corresponding decrease in the interplanetary magnetic field (IMF) strength, by a ∼20% shrinkage in the polar coronal-hole areas, and by a reduction in the solar-wind mass flux over the poles. It has also been reflected in coronal streamer structure and the heliospheric current sheet, which only showed the expected flattening into the equatorial plane after sunspot numbers fell to unusually low values in mid-2008. From latitude-time plots of the photospheric field, it has long been apparent that the polar fields are formed through the transport of trailing-polarity flux from the sunspot latitudes to the poles. To address the question of why the polar fields are now so weak, we simulate the evolution of the photospheric field and radial IMF strength from 1965 to the present, employing a surface transport model that includes the effects of active region emergence, differential rotation, supergranular convection, and a poleward bulk flow. We find that the observed evolution can be reproduced if the amplitude of the surface meridional flow is varied by as little as 15% (between 14.5 and 17 m s -1 ), with the higher average speeds being required during the long cycles 20 and 23.

  13. Future equivalent of 2010 Russian heatwave intensified by weakening soil moisture constraints

    The 2010 heatwave in eastern Europe and Russia ranks among the hottest events ever recorded in the region1,2. The excessive summer warmth was related to an anomalously widespread and intense quasi-stationary anticyclonic circulation anomaly over western Russia, reinforced by depletion of spring soil moisture1,3-5. At present, high soil moisture levels and strong surface evaporation generally tend to cap maximum summer temperatures6-8, but these constraints may weaken under future warming9,10. Here, we use a data assimilation technique in which future climate model simulations are nudged to realistically represent the persistence and strength of the 2010 blocked atmospheric flow. In the future, synoptically driven extreme warming under favourable large-scale atmospheric conditions will no longer be suppressed by abundant soil moisture, leading to a disproportional intensification of future heatwaves. This implies that future mid-latitude heatwaves analogous to the 2010 event will become even more extreme than previously thought, with temperature extremes increasing by 8.4 °C over western Russia. Thus, the socioeconomic impacts of future heatwaves will probably be amplified beyond current estimates.

    The Framework Convention on Tobacco Control (FCTC) contains no provisions covering tobacco industry investments. This creates the potential for tobacco companies to benefit from investment liberalisation by using foreign investments to avoid tobacco tariffs, increase tobacco consumption and otherwise impair the implementation of FCTC-style measures. Reducing and ultimately eliminating foreign investment activities by tobacco companies can be justified on health grounds, even though it runs counter to current investment liberalisation trends. Through the FCTC process, non-binding guidelines can be elaborated to assist parties in recognising and responding to foreign investment strategies of tobacco companies, to support efforts to exclude the tobacco sector from investment liberalisation and otherwise would improve all countries' awareness of the threat from foreign investment strategies of tobacco companies and provide them with approaches to handle the problems.

    Tobacco is the world's biggest preventable killer, but the circumstances of its history, the power and influence of its commerce and the nature of addiction make it a very difficult public health issue. Determinants of smoking are both individual and environmental. Genetics and environment influence to varying degrees all of the steps in a smoker's career. Persistence of use, degree of addiction to nicotine and difficulty in stopping are influenced by inherited traits and nicotine susceptibility, whereas the social environment and the individual's cognitions are the key factors in starting smoking and successfully stopping smoking. The tools available to tobacco control include influencing the social and cultural norms concerning tobacco; legislative and regulatory measures to protect the population and to limit tobacco industry marketing tactics, now encapsulated in the Framework Convention on Tobacco Control; and programmes to enhance the chance of not starting and successfully stopping. Strategies for tobacco control must work at both societal and individual levels, and directions are being taken that include genetic, pharmacological, behavioural, socio-cultural and international approaches.

    Tobacco companies have come under increased criticism because of environmental and labour practices related to growing tobacco in developing countries. Analysis of tobacco industry documents, industry websites and interviews with tobacco farmers in Tanzania and tobacco farm workers, farm authorities, trade unionists, government officials and corporate executives from global tobacco leaf companies in Malawi. British American Tobacco and Philip Morris created supply chains in the 1990 s to improve production efficiency, control, access to markets and profits. In the 2000s, the companies used their supply chains in an attempt to legitimise their portrayals of tobacco farming as socially and environmentally friendly, rather than take meaningful steps to eliminate child labour and reduce deforestation in developing countries. The tobacco companies used nominal self-evaluation (not truly independent evaluators) and public relations to create the impression of social responsibility. The companies benefit from $1.2 billion in unpaid labour costs because of child labour and more than $64 million annually in costs that would have been made to avoid tobacco-related deforestation in the top 12 tobacco growing developing countries, far exceeding the money they spend nominally working to change these practices. The tobacco industry uses green supply chains to make tobacco farming in developing countries appear sustainable while continuing to purchase leaf produced with child labour and high rates of deforestation. Strategies to counter green supply chain schemes include securing implementing protocols for the WHO Framework Convention on Tobacco Control to regulate the companies' practices at the farm level.

    Tobacco control in China, the world's largest producer and consumer of tobacco, began in the 1980s with the first national prevalence survey and a conference on tobacco held in Tianjin. Since then, there have been dozens of research papers, partial restrictions on smoking and tobacco advertising, public education campaigns, and the ratification of the World Health Organization Framework Convention on Tobacco Control, but progress has been slow. The state-owned tobacco industry remains a major obstacle to tobacco control. In the last few years, tobacco control efforts have accelerated beyond expectations. The triggering event was the publication on tobacco by the Chinese Central Party School, the ideological think tank of the Communist Party, followed by a spate of activity: directives to government officials; regulations issued by the Ministry of Education, the People's Liberation Army and the Healthy City Standards; tobacco clauses in national advertising and philanthropy laws; the creation of a Smoke-free Beijing; an increase in tobacco taxation; and a national smoke-free law currently in draft. There is a crucial need for China to build upon these recent developments, in accepting the economic research evidence of the debit of tobacco to the economy; in implementing robust, comprehensive legislation; in increasing cigarette price through taxation and, most challenging of all, to tackle the power and influence of the state tobacco monopoly over tobacco control. © The Author 2016.

    Marketers have long recognized the power and importance of branding, which creates aspirational attributes that increase products' attractiveness. Although brand imagery has traditionally been communicated via mass media, packaging's importance in promoting desirable brand-attribute associations has increased. Knowledge of how groups prone to smoking experimentation interpret tobacco branding would inform the debate over plain packaging currently occurring in many countries. We conducted 12 group discussions and four in-depth interviews with 66 young adult smokers and nonsmokers of varying ethnicities from two larger New Zealand cities and one provincial city. Participants evaluated 10 familiar and unfamiliar tobacco brands using brand personality attributes and discussed the associations they had made. Participants ascribed very different images to different brands when exposed to the packaging alone, regardless of whether they had seen or heard of the brands before. Perceptual mapping of brands and image attributes highlighted how brand positions varied from older, more traditional, and male oriented to younger, feminine, and "cool." Our findings emphasize the continuing importance of tobacco branding as a promotion tool, even when communicated only by packaging. The ease with which packaging alone enabled young people to identify brand attributes and the desirable associations these connoted illustrate how tobacco packaging functions as advertising. The results support measures such as plain packaging of tobacco products to reduce exposure to these overt behavioral cues.

    Full Text Available In the US, denormalizing tobacco use is key to tobacco control; less attention has been paid to denormalizing tobacco sales. However, some localities have placed limits on the number and type of retailers who may sell tobacco, and some retailers have abandoned tobacco sales voluntarily. Understanding community norms surrounding tobacco sales may help accelerate tobacco denormalization.We conducted 15 focus groups with customers of California, New York, and Ohio retailers who had voluntarily discontinued tobacco sales to examine normative assumptions about where cigarettes should or should not be sold, voluntary decisions to discontinue tobacco sales, and government limits on such sales.Groups in all three states generally agreed that grocery stores that sold healthy products should not sell tobacco; California groups saw pharmacies similarly, while this was a minority opinion in the other two states. Convenience stores were regarded as a natural place to sell tobacco. In each state, it was regarded as normal and commendable for some stores to want to stop selling tobacco, although few participants could imagine convenience stores doing so. Views on government's role in setting limits on tobacco sales varied, with California and New York participants generally expressing support for restrictions, and Ohio participants expressing opposition. However, even those who expressed opposition did not approve of tobacco sales in all possible venues. Banning tobacco sales entirely was not yet normative.Limiting the ubiquitous availability of tobacco sales is key to ending the tobacco epidemic. Some limits on tobacco sales appear to be normative from the perspective of community members; it may be possible to shift norms further by problematizing the ubiquitous presence of cigarettes and drawing connections to other products already subject to restrictions.

    The Sunrise balloon-borne solar observatory, consisting of a 1 m aperture telescope that provides a stabilized image to a UV filter imager and an imaging vector polarimeter, carried out its second science flight in 2013 June. It provided observations of parts of active regions at high spatial resolution, including the first high-resolution images in the Mg ii k line. The obtained data are of very high quality, with the best UV images reaching the diffraction limit of the telescope at 3000 Å after Multi-Frame Blind Deconvolution reconstruction accounting for phase-diversity information. Here a brief update is given of the instruments and the data reduction techniques, which includes an inversion of the polarimetric data. Mainly those aspects that evolved compared with the first flight are described. A tabular overview of the observations is given. In addition, an example time series of a part of the emerging active region NOAA AR 11768 observed relatively close to disk center is described and discussed in some detail. The observations cover the pores in the trailing polarity of the active region, as well as the polarity inversion line where flux emergence was ongoing and a small flare-like brightening occurred in the course of the time series. The pores are found to contain magnetic field strengths ranging up to 2500 G, and while large pores are clearly darker and cooler than the quiet Sun in all layers of the photosphere, the temperature and brightness of small pores approach or even exceed those of the quiet Sun in the upper photosphere.

    Background Smoking in Hollywood movies is a known risk factor for teen smoking in the USA and Europe, but little is known about the association between exposure to tobacco use in Bollywood movies and teen tobacco use in India. Methods A cross-sectional sample of 3956 adolescents (eighth and ninth grades, ages 12–16 years) from 12 randomly selected New Delhi schools was surveyed in 2009, assessing tobacco use status, receptivity to tobacco promotions (based on owning or being willing to wear tobacco-branded merchandise) and exposure to tobacco use in movies. Quartiles of exposure to tobacco use in popular Bollywood movies released from 2006 to 2008 (n=59) were determined by content coding them for tobacco use and querying the adolescents whether they had seen each one. Logistic regression was used to control for covariates including age, gender, parent education, school performance, sensation-seeking propensity, family and peer tobacco use, and authoritative parenting. Results Altogether, the 59 movies contained 412 tobacco use occurrences. The prevalence of ever tobacco use among adolescents was 5.3%. Compared with low-exposure adolescents (quartile 1), the adjusted odds of ever tobacco use among high-exposure adolescents (quartile 4) was 2.3 (95% CI 1.3 to 3.9). Being receptive to tobacco promotions was also associated with higher adjusted odds of ever tobacco use, 2.0 (95% CI 1.4 to 3.0). Conclusion Watching tobacco use in Bollywood movies and receptivity to tobacco promotional activities were both independently associated with ever tobacco use among adolescents in India, with ORs being similar to the studies of adolescents elsewhere.

    Full Text Available Nonnative disulfide bonds have been observed among protein aggregates in several diseases like amyotrophic lateral sclerosis, cataract and so on. The molecular mechanism by which formation of such bonds promotes protein aggregation is poorly understood. Here in this work we employ previously well characterized aggregation of hen eggwhite lysozyme (HEWL at alkaline pH to dissect the molecular role of nonnative disulfide bonds on growth of HEWL aggregates. We employed time-resolved fluorescence anisotropy, atomic force microscopy and single-molecule force spectroscopy to quantify the size, morphology and non-covalent interaction forces among the aggregates, respectively. These measurements were performed under conditions when disulfide bond formation was allowed (control and alternatively when it was prevented by alkylation of free thiols using iodoacetamide. Blocking disulfide bond formation affected growth but not growth kinetics of aggregates which were ∼50% reduced in volume, flatter in vertical dimension and non-fibrillar in comparison to control. Interestingly, single-molecule force spectroscopy data revealed that preventing disulfide bond formation weakened the non-covalent interaction forces among monomers in the aggregate by at least ten fold, thereby stalling their growth and yielding smaller aggregates in comparison to control. We conclude that while constrained protein chain dynamics in correctly disulfide bonded amyloidogenic proteins may protect them from venturing into partial folded conformations that can trigger entry into aggregation pathways, aberrant disulfide bonds in non-amyloidogenic proteins (like HEWL on the other hand, may strengthen non-covalent intermolecular forces among monomers and promote their aggregation.

    Full Text Available AIM: To analyse the variation of horizontal deviation in the primary position after the inferior oblique muscle weakening, and to explore the effect of the inferior oblique muscle recession on horizontal deviations in primary position.METHODS:, In the study, 30 cases in the Department of ophthalmology of our hospital from January 2014 to September 2014 underwent the inferior oblique muscle recession as the sole without horizontal muscles surgery, who were superior obliquer paralysis and V pattern strabismus with small angle of horizontal strabismus, were analyzed. Of the 30 patients, 25 had unilateral inferior oblique muscle surgery, and then 5 had bilateral surgeries.Followed up for three to six mo, all patients were received full ophthalmologic and orthoptic examinations, including measurement of the deviation in the diagnostic positions of gaze at near 33cm and at distance 6m by prism and alternate cover test, synoptophore, Titmus stereo graph examination, Worth four lighting inspection, eye movement examination, and fundus photography preoperatively and postoperatively. The changes of horizontal deviations in the primary position after procedures were investigated. RESULT:(1The comparison of horizontal deviation showed significant difference pre- and post-operation in the exotropia group(P=0.00. It was postoperative respectively to reduce the original in external oblique average 3.35±2.87△ and 4.37±2.65△.(2The comparison of horizontal deviation showed significant difference pre-and post-operation in the esotropia group(P=0.02, and it decreased postoperatively in average 2.43±1.99△. There was no significant difference for horizontal deviation position between pre- and post-operation(P=0.089. CONCLUSION:The horizontal deviation in primary position, either exotropia or esotropia, will decrease after the Inferior oblique muscle recession. This change can be compensated by the gradually improving and establishing the fusion function.

    System memory consolidation is conceptualized as an active process whereby newly encoded memory representations are strengthened through selective memory reactivation during sleep. However, our learning experience is highly overlapping in content (i.e., shares common elements), and memories of these events are organized in an intricate network of overlapping associated events. It remains to be explored whether and how selective memory reactivation during sleep has an impact on these overlapping memories acquired during awake time. Here, we test in a group of adult women and men the prediction that selective memory reactivation during sleep entails the reactivation of associated events and that this may lead the brain to adaptively regulate whether these associated memories are strengthened or pruned from memory networks on the basis of their relative associative strength with the shared element. Our findings demonstrate the existence of efficient regulatory neural mechanisms governing how complex memory networks are shaped during sleep as a function of their associative memory strength. SIGNIFICANCE STATEMENT Numerous studies have demonstrated that system memory consolidation is an active, selective, and sleep-dependent process in which only subsets of new memories become stabilized through their reactivation. However, the learning experience is highly overlapping in content and thus events are encoded in an intricate network of related memories. It remains to be explored whether and how memory reactivation has an impact on overlapping memories acquired during awake time. Here, we show that sleep memory reactivation promotes strengthening and weakening of overlapping memories based on their associative memory strength. These results suggest the existence of an efficient regulatory neural mechanism that avoids the formation of cluttered memory representation of multiple events and promotes stabilization of complex memory networks.

    Fire suppression allows tree species that are intolerant of fire stress to increase their distribution, potentially resulting in disruption of historical species-environmental relationships. To measure changes between historical General Land Office surveys (1815 to 1850) and current USDA Forest Inventory and Assessment surveys (2004 to 2008), we compared composition, distribution, and site factors of 21 tree species or species groups in the Missouri Ozarks. We used 24 environmental variables and random forests as a classification method to model distributions. Eastern redcedar, elms, maples, and other fire-sensitive species have increased in dominance in oak forests, with concurrent reductions by oak species; specific changes varied by ecological subsection. Ordinations displayed loss of separation between formerly distinctive oak and fire-sensitive tree species groups. Distribution maps showed decreased presence of disturbance-dependent oak and pine species and increased presence of fire-sensitive species that generally expanded from subsections protected from fire along rivers to upland areas, except for eastern redcedar, which expanded into these subsections. Large scale differences in spatial gradients between past and present communities paralleled reduced influence of local topographic gradients in the varied relief of the Missouri Ozarks, as fire-sensitive species have moved to higher, drier, and sunnier sites away from riverine corridors. Due to changes in land use, landscapes in the Missouri Ozarks, eastern United States, and world-wide are changing from open oak and pine-dominated ecosystems to novel oak-mixed species forests, although at fine scales, forests are becoming more diverse in tree species today. Fire suppression weakened the influence by environmental gradients over species dominance, allowing succession from disturbance-dependent oaks to an alternative state of fire-sensitive species.

  9. Feelings of disgust and disgust-induced avoidance weaken following induced sexual arousal in women.

    Directory of Open Access Journals (Sweden)

    Charmaine Borg

    Full Text Available BACKGROUND: Sex and disgust are basic, evolutionary relevant functions that are often construed as paradoxical. In general the stimuli involved in sexual encounters are, at least out of context strongly perceived to hold high disgust qualities. Saliva, sweat, semen and body odours are among the strongest disgust elicitors. This results in the intriguing question of how people succeed in having pleasurable sex at all. One possible explanation could be that sexual engagement temporarily reduces the disgust eliciting properties of particular stimuli or that sexual engagement might weaken the hesitation to actually approach these stimuli. METHODOLOGY: Participants were healthy women (n = 90 randomly allocated to one of three groups: the sexual arousal, the non-sexual positive arousal, or the neutral control group. Film clips were used to elicit the relevant mood state. Participants engaged in 16 behavioural tasks, involving sex related (e.g., lubricate the vibrator and non-sex related (e.g., take a sip of juice with a large insect in the cup stimuli, to measure the impact of sexual arousal on feelings of disgust and actual avoidance behaviour. PRINCIPAL FINDINGS: The sexual arousal group rated the sex related stimuli as less disgusting compared to the other groups. A similar tendency was evident for the non-sex disgusting stimuli. For both the sex and non-sex related behavioural tasks the sexual arousal group showed less avoidance behaviour (i.e., they conducted the highest percentage of tasks compared to the other groups. SIGNIFICANCE: This study has investigated how sexual arousal interplays with disgust and disgust eliciting properties in women, and has demonstrated that this relationship goes beyond subjective report by affecting the actual approach to disgusting stimuli. Hence, this could explain how we still manage to engage in pleasurable sexual activity. Moreover, these findings suggest that low sexual arousal might be a key feature in the

  11. On the initiation of sustained slip-weakening ruptures by localized stresses

    KAUST Repository

    Galis, Martin

    2014-12-10

    Numerical simulations of dynamic earthquake rupture require an artificial initiation procedure, if they are not integrated in long-term earthquake cycle simulations. A widely applied procedure involves an \\'overstressed asperity\\', a localized region stressed beyond the static frictional strength. The physical properties of the asperity (size, shape and overstress) may significantly impact rupture propagation. In particular, to induce a sustained rupture the asperity size needs to exceed a critical value. Although criteria for estimating the critical nucleation size under linear slip-weakening friction have been proposed for 2-D and 3-D problems based on simplifying assumptions, they do not provide general rules for designing 3-D numerical simulations. We conduct a parametric study to estimate parameters of the asperity that minimize numerical artefacts (e.g. changes of rupture shape and speed, artificial supershear transition, higher slip-rate amplitudes). We examine the critical size of square, circular and elliptical asperities as a function of asperity overstress and background (off-asperity) stress. For a given overstress, we find that asperity area controls rupture initiation while asperity shape is of lesser importance. The critical area obtained from our numerical results contrasts with published theoretical estimates when background stress is low. Therefore, we derive two new theoretical estimates of the critical size under low background stress while also accounting for overstress. Our numerical results suggest that setting the asperity overstress and area close to their critical values eliminates strong numerical artefacts even when the overstress is large. We also find that properly chosen asperity size or overstress may significantly shorten the duration of the initiation. Overall, our results provide guidelines for determining the size of the asperity and overstress to minimize the effects of the forced initiation on the subsequent spontaneous

    Smoking in films is a common and well documented cause of youth smoking experimentation and uptake and hence a significant health hazard. The extent of exposure of young people to tobacco imagery in television programming has to date been far less investigated. We have therefore measured the extent to which tobacco content occurs in prime time UK television, and estimated exposure of UK youth. The occurrence of tobacco, categorised as actual tobacco use, implied tobacco use, tobacco paraphernalia, other reference to tobacco, tobacco brand appearances or any of these, occurring in all prime time broadcasting on the five most popularly viewed UK television stations during 3 separate weeks in 2010 were measured by 1-minute interval coding. Youth exposure to tobacco content in the UK was estimated using media viewing figures. Actual tobacco use, predominantly cigarette smoking, occurred in 73 of 613 (12%) programmes, particularly in feature films and reality TV. Brand appearances were rare, occurring in only 18 programmes, of which 12 were news or other factual genres, and 6 were episodes of the same British soap opera. Tobacco occurred with similar frequency before as after 21:00, the UK watershed for programmes suitable for youth. The estimated number of incidences of exposure of the audience aged less than 18 years for any tobacco, actual tobacco use and tobacco branding were 59 million, 16 million and 3 million, respectively on average per week. Television programming is a source of significant exposure of youth to tobacco imagery, before and after the watershed. Tobacco branding is particularly common in Coronation Street, a soap opera popular among youth audiences. More stringent controls on tobacco in prime time television therefore have the potential to reduce the uptake of youth smoking in the UK.

    Full Text Available Background Tobacco use prevalence in Africa is projected to rise over the next 15 years without stronger tobacco control measures. However, little research details the scope of tobacco control research being conducted in Africa. A systematic literature review was conducted to better understand the landscape of tobacco control efforts in Africa. Methods A literature search of tobacco research conducted in all African countries from 1996 to 2016 was performed in PubMed, Embase, and African Index Medicus. Published abstracts meeting the inclusion criteria of focusing on nicotine or tobacco product(s and having been conducted in one or more African countries were selected for full coding and analysis. The authors coded on study characteristics such as type of research, tobacco product, and country. Three coders double-coded 5% of the articles reviewed to ensure agreement. Results This review found 645 relevant articles, in French and English, representing 52 African countries. South Africa was the focus of the greatest proportion of these published tobacco control research articles (23%, followed by Nigeria (17%, Egypt (13%, and Tunisia (12%. Reporting the prevalence of tobacco use was the focus of 51% of these articles. Other areas of research included the potential determinants of tobacco use (28%; knowledge, attitudes, and beliefs about tobacco products or policies (26%; and biological consequences of tobacco use (25%. Most studies (63% discussed cigarettes, and 15% studied smokeless tobacco. Youth-targeted studies comprised 25% of all research in Africa. Publications per year increased between 1996 and 2015, quadrupling in number by 2015. Conclusions A comprehensive review of the literature provides a baseline understanding of the tobacco control landscape and the increased attention countries are showing to tobacco and tobacco control.

The estimated number of incidences of exposure of the audience aged less than 18 years for any tobacco, actual tobacco use and tobacco branding were 59 million, 16 million and 3 million, respectively on average per week. Conclusions Television programming is a source of significant exposure of youth to tobacco imagery, before and after the watershed. Tobacco branding is particularly common in Coronation Street, a soap opera popular among youth audiences. More stringent controls on tobacco in prime time television therefore have the potential to reduce the uptake of youth smoking in the UK. PMID:23479113

    The chlorine and bromine contents in tobacco and tobacco smoke in both the particulate and gaseous phases were studied by neutron activation analysis. Eleven popular brands of western filter cigarettes were tested. Methyl chloride and methyl bromide concentrations were measured in the gaseous phase in two leading brands in Finland. The results suggest that the mainstream smoke from one cigarette conveys into the lungs about 150 μg chlorine and about 5 μg bromine. Probably most of the chlorine and bromine is in the form of organic compounds and the main components are methyl chloride and methyl bromide. (author) 14 refs.; 1 tab

  18. Salivary cotinine levels as a biomarker for green tobacco sickness in dry tobacco production among Thai traditional tobacco farmers.

    Dry Thai traditional tobacco (Nicotiana Tabacum L.) production involves a unique process: (a) picking tobacco leaves, (b) curing tobacco leaves, (c) removing stems of tobacco leaves, cutting leaves and putting on a bamboo rack, (d) drying in the sun, reversing a rack, spraying a tobacco extract to adjust the tobacco's color, storing dried tobacco and packaging. These processes may lead to adverse health effects caused by dermal absorption of nicotine such as Green Tobacco Sickness (GTS). The aim of this study was to determine the correlation between GTS resulting from dry Thai traditional tobacco production and salivary cotinine levels among Thai traditional tobacco farmers in Nan Province, Thailand. A prospective cohort study was conducted with 20 tobacco farmers and 20 non-tobacco farmers in Praputtabath Sub-District and Phatow Sub-District. The participants were randomly selected and interviewed using in person questionnaires with bi-weekly follow-up for 14 weeks. During each contact, the cotinine concentration was measured by NicAlert(TM) Saliva strip tests (NCTS). Descriptive statistics and Spearman's correlation (Spearman's rho) was used to examine the relationship between the variables at both 0.01 and 0.05 significant probability levels. This study indicated that GTS from dry tobacco production has the potential to be considered a common occupational disease. This study demonstrated the usefulness of salivary cotinine level measurements by NCTS. The levels were well correlated with farmers who were employed in the dry Thai tobacco production industry. Salivary cotinine levels were also significantly correlated with the prevalence of GTS in the group of tobacco farmers at any given time within a crop season. However, the production process of dry Thai traditional tobacco is different from that evaluated in our previous studies where GTS and salivary cotinine level were correlated in workers working in humid conditions. The long-term effects of such exposure

    Full Text Available The study aimed to evaluate the yield and fruit quality of papaya ‘Sunrise Solo’ as function of nitrogen and boron fertilization. The experiment had a randomized block design with four replications, two plants per plot with a single border. To make up the treatments, we used the experimental array Plan Puebla III, which set the rates for nitrogen (0.0 to 111.2 - 200 – 288.9 - 400 g plant-1, and B (0.0 – 0.83 - 1.5 – 2.16 - 3.0 g plant-1, in a total of ten treatments. The addition of nitrogen increased the yield, average fruit weight and number of fruits per plant. The nitrogen and boron increased the diameter and length of the fruit, amount of seeds and content of soluble solids. The pH of the pulp decreased linearly with increasing doses of nitrogen and boron. It was observed a significant effect of N rates on the level of vitamin C.O trabalho teve como objetivo avaliar a produtividade e a qualidade de frutos de mamoeiro ‘Sunrise Solo’ em função de doses de nitrogênio e boro.

    The link between cigarette smoke and cancer has long been established. Smokers are ten times at greater risk of developing lung cancer than that of non-smokers. Tobacco fields and plants also have higher concentration of uranium and consequently large contents of 210 Po and 210 Pb belonging to uranium and radium decay series. These radio-nuclides have long association with tobacco plants. 210 Pb and 210 Po, decay products of the uranium series get dissolved in water and are first transported into plants and subsequently to the human being. Also, the uptake of radionuclides into roots from the soils and phosphate fertilizers along with direct deposition of 210 Pb by rainfall represents the principal mechanism of incorporation of 210 Pb and 210 Po into the tobacco plants. Uranium present in soil enters the plants through roots and gets distributed in various parts of the tobacco plants. This phenomenon may cause high intake of uranium and its radioactive decay products leading to harmful effects in human being. In the present work, Gamma spectrometry (HPGe detector of high-resolution gamma spectrometry system) has been used at Inter University Accelerator Center (IUAC), New Delhi, for the measurement of activity concentrations of 238 U, 232 Th and 40 K in some tobacco samples. The alpha radioactivity of the leaves of the tobacco plants was measured using plastic track detectors LR-115 Type-Il manufactured by Kodak. Measurement of track densities (track cm -2 day -1 ) shows variation on the upper face and the bottom face of the leaves for the plants. The track density due to alpha particles is higher at bottom face as compared to top face of the leaves. (author)

Using data from the Global Youth Tobacco Survey (GYTS), the exposure to tobacco marketing at the school level was studied from advertising in TV, radio, massive public events and street advertisement. Tobacco behaviour was considered. The total pooled sample used was 134 073 youths from Argentina, Bolivia, Chile, Peru, Brazil, Uruguay, Suriname, Colombia, Guyana, Ecuador, Paraguay and Venezuela. The exposure to tobacco marketing is positively and significantly associated to the probability of youths experimenting with tobacco (at least once in their lifetime). For regular smokers, exposure to tobacco marketing is positively and significantly associated to smoking intensity. These results call for the implementation of strong restrictions on tobacco advertisement of various types in South American countries.

  20. Increases in aerosol concentrations over eastern China due to the decadal-scale weakening of the East Asian summer monsoon

    Science.gov (United States)

    Zhu, Jianlei; Liao, Hong; Li, Jianping

    2012-05-01

    China has been experiencing increased concentrations of aerosols, commonly attributed to the large increases in emissions associated with the rapid economic development. We show by using a chemical transport model driven by the assimilated meteorological fields that the observed decadal-scale weakening of the East Asian summer monsoon also contributed to the increases in aerosols in China. We find that the simulated aerosol concentrations have strong negative correlations with the strength of the East Asian Summer monsoon. Accounting for sulfate, nitrate, ammonium, black carbon, and organic carbon aerosols, the summer surface-layer PM2.5 concentration averaged over eastern China (110°-125°E, 20°-45°N) can be 17.7% higher in the weakest monsoon years than in the strongest monsoon years. The weakening of the East Asian Summer monsoon increases aerosol concentrations mainly by the changes in atmospheric circulation (the convergence of air pollutants) in eastern China.

    Full Text Available En este trabajo presentamos un ejercicio narrativo acerca de la acción social y las teorías hermenéuticas que han intentado definir o hablar acerca de la misma. Se recogen propuestas diversas: desde las que abogan por considerar a la acción social como un texto hasta las consideraciones más pragmatistas acerca del para qué de la acción. En este relato se pone en juego, en el más puro sentido gadameriano, una ficción que tiene la virtud de tematizar y poner en acto, simultáneamente, un concepto que teóricamente ha sido elusivo. Este abordaje asume la sutil noción de narración ficticia que, de acuerdo a Paul Ricoeur, tiene la característica paradójica de que entre más irreal se sitúa una lectura, es más profunda y lejana su influencia sobre la realidad social. Por otro lado, coincidimos con Alfred Schutz en que, al abandonarnos a la risa, hay un ámbito de significado que otorga realidad al mundo ficticio y resignifica el mundo de la vida cotidiana.

  12. The role of tobacco advertising and promotion: themes employed in litigation by tobacco industry witnesses.

    Goldberg, Marvin E; Davis, Ronald M; O'Keefe, Anne Marie

    2006-12-01

    To identify key themes related to tobacco advertising and promotion in testimony provided by tobacco industry-affiliated witnesses in tobacco litigation, and to present countervailing evidence and arguments. Themes in industry testimony were identified by review of transcripts of testimony in the Tobacco Deposition and Trial Testimony Archive (http://tobaccodocuments.org/datta) from a sample of defence witnesses, including three academic expert witnesses, six senior executives of tobacco companies, and one industry advertising consultant. Counterarguments to the themes embodied in defence testimony were based on information from peer-reviewed literature, advertising trade publications, government reports, tobacco industry documents, and testimony provided by expert witnesses testifying for plaintiffs. Five major themes employed by defence witnesses were identified: (1) tobacco advertising has a relatively weak "share of voice" in the marketing environment and is a weak force in affecting smoking behaviour; (2) tobacco advertising and promotion do not create new smokers, expand markets, or increase total tobacco consumption; (3) the tobacco industry does not target, study, or track youth smoking; (4) tobacco advertising and promotion do not cause smoking initiation by youth; and (5) tobacco companies and the industry adhere closely to relevant laws, regulations, and industry voluntary codes. Substantial evidence exists in rebuttal to these arguments. Tobacco industry-affiliated witnesses have marshalled many arguments to deny the adverse effects of tobacco marketing activities and to portray tobacco companies as responsible corporate citizens. Effective rebuttals to these arguments exist, and plaintiffs' attorneys have, with varying degrees of success, presented them to judges and juries.

  14. Social Responsibility in Tobacco Production? Tobacco Companies Use of Green Supply Chains to Obscure the Real Costs of Tobacco Farming

    Science.gov (United States)

    Otañez, Marty

    2011-01-01

    Background Tobacco companies have come under increased criticism because of environmental and labor practices related to growing tobacco in developing countries. Methods Analysis of tobacco industry documents, industry web sites and interviews with tobacco farmers in Tanzania and tobacco farm workers, farm authorities, trade unionists, government officials and corporate executives from global tobacco leaf companies in Malawi. Results British American Tobacco and Philip Morris created supply chains in the 1990s to improve production efficiency, control, access to markets, and profits. In the 2000s, the companies used their supply chains in an attempt to legitimize their portrayals of tobacco farming as socially and environmentally friendly, rather than take meaningful steps to eliminate child labor and reduce deforestation in developing countries. The tobacco companies used nominal self-evaluation (not truly independent evaluators) and public relations to create the impression of social responsibility. The companies benefit from $1.2 billion in unpaid labor costs due to child labor and more than $64 million annually in costs that would have been made to avoid tobacco related deforestation in the top twelve tobacco growing developing countries, far exceeding the money they spend nominally working to change these practices. Conclusions The tobacco industry uses green supply chains to make tobacco farming in developing countries appear sustainable while continuing to purchase leaf produced with child labor and high rates of deforestation. Strategies to counter green supply chain schemes include securing implementing protocols for the WHO Framework Convention on Tobacco Control to regulate the companies’ practices at the farm level.

    Youth who engage with online tobacco marketing may be more susceptible to tobacco use than unengaged youth. This study examines online engagement with tobacco marketing and its association with tobacco use patterns. Cross-sectional analysis of youths aged 12-17 years who participated in wave 1 of the Population Assessment of Tobacco and Health Study (N = 13,651). Engagement with tobacco marketing was based on 10 survey items including signing up for email alerts about tobacco products in the past 6 months. Logistic regression was used to examine the association of online engagement with tobacco marketing and susceptibility to use any tobacco product among never-tobacco users, ever having tried tobacco, and past 30-day tobacco use. An estimated 2.94 million U.S. youth (12%) engaged with ≥ one forms of online tobacco marketing. Compared with no engagement, the odds of susceptibility to the use of any tobacco product among never-tobacco users was independently associated with the level of online engagement: adjusted odds ratio (AOR) = 1.48 (95% confidence interval [CI], 1.24-1.76) for one form of engagement and AOR = 2.37 (95% CI, 1.53-3.68) for ≥ two forms of engagement. The odds of ever having tried tobacco were also independently associated with the level of online engagement: AOR = 1.33 (95% CI: 1.11-1.60) for one form of engagement and AOR = 1.54 (95% CI, 1.16-2.03) for ≥ two forms of engagement. The level of online engagement was not independently associated with past 30-day tobacco use. Online engagement with tobacco marketing may represent an important risk factor for the onset of tobacco use in youth. Copyright © 2017 Society for Adolescent Health and Medicine.

    Objectives The objective of the present study was to evaluate how effective tobacco tax increase has been in increasing price of tobacco products and reducing tobacco consumption in the Gambia. In addition, it tests the hypothesis that tobacco tax revenue grows while tobacco consumption decreases as a result of tax and price increase. Setting The study is designed at the macroeconomic level to examine the import of tobacco products and revenue collected from tobacco taxation in a low-income setting. Participants The participants of this study are the government officials employed in the Ministry of Finance and Economic Affairs (MoFEA), the Gambia and the Gambia Revenue Authority, who are in charge of planning and implementing the tobacco tax policy in the Gambia. Interventions The study includes 2 consecutive interventions in tobacco tax policy in the Gambia. The first intervention was moving the tax base for the uniform specific excise tax on cigarettes from weight to pack of cigarettes in 2013. The second intervention involved increasing the excise and the environmental tax on tobacco products in 2014. Primary and secondary outcome measures The primary outcome measures were the cost, insurance and freight value and the price of tobacco products. The secondary outcome measures included the import of tobacco products and tobacco tax revenue. Results In 2013–2014, the Gambia MoFEA raised the specific excise rate, which increased price, reduced consumption and generated significantly more government revenue from tobacco products. This is a clear evidence of the win-win outcome of raising tobacco tax. In addition, the Gambia has set the example of harmonising tax rates between tobacco products that reduces the substitution between tobacco products. Conclusions The Gambia presents the best practice in tobacco taxation. There is need for documenting more country-specific evidence on the win-win outcome of raising tobacco tax. PMID:27566626

    The effect of any legislation depends on its implementation. Limited studies indicate that tobacco companies may tend to use such provision for surrogate advertising. The point of sale advertisement provision has been placed in the Indian Tobacco Control legislation. The study was undertaken to assess the Indian scenario in this regard. To assess if there are any violations related to provision of point of tobacco sale advertisements under India's comprehensive tobacco Control legislation in different parts of India. Boards over various shops showing advertisements of tobacco products were observed in the cities of Delhi, Mumbai, Kolkata, Trivandrum and Jaipur, between September 2005 and March 2006. The point of sale advertisements mushroomed after the implementation of 2004 tobacco control legislation. Tobacco advertisement boards fully satisfying the point of sale provision were practically non-existent. The most common violation of point of sale advertisements was the larger size of the board but with tobacco advertisement equal to the size indicated in the legislation and remaining area often showing a picture. Invariably two boards were placed together to provide the impression of a large single repetitive advertisement. More than two boards was not common. Tobacco advertisement boards were also observed on closed shops/ warehouses, shops not selling tobacco products and on several adjacent shops. The purpose of the point of sale advertisements seems to be surrogate advertisement of tobacco products, mainly cigarettes.

    Over the last 50 years, tobacco has been excluded from and then included in the category of addictive substances. We investigated influences on these opposing definitions and their application in expert witness testimony in litigation in the 1990s and 2000s. A scientist with ties to the tobacco industry influenced the selection of a definition of addiction that led to the classification of tobacco as a "habituation" in the 1964 Surgeon General's Advisory Committee report. Tobacco was later defined as addictive in the 1988 surgeon general's report. Expert witnesses for tobacco companies used the 1964 report's definition until Philip Morris Tobacco Company publicly changed its position in 1997 to agree that nicotine was addictive. Expert witnesses for plaintiffs suing the tobacco industry used the 1988 report's definition, arguing that new definitions were superior because of scientific advance. Both sides viewed addiction as an objective entity that could be defined more or less accurately.

    The tobacco industry has developed an extensive array of strategies and arguments to prevent or weaken government regulation. These strategies and arguments are well documented at the domestic level. However, there remains a need to examine how these arguments are reflected in the challenges waged by governments within the World Trade Organization (WTO). Decisions made at the WTO have the potential to shape how countries govern. Our analysis was conducted on two novel tobacco control measures: tobacco additives bans (Canada, United States and Brazil) and plain, standardized packaging of tobacco products (Australia, New Zealand, Ireland, EU and UK). We analyzed WTO documents (i.e. meeting minutes and submissions) (n = 62) in order to identify patterns of argumentation and compare these patterns with well-documented industry arguments. The pattern of these arguments reveal that despite the unique institutional structure of the WTO, country representatives opposing novel tobacco control measures use the same non-technical arguments as those that the tobacco industry continues to use to oppose these measures at the domestic level.

    The aim of this study was to examine tobacco use among working adults at least 18 years of age. The 2012 to 2014 National Health Interview Survey (n = 105,779) was used to estimate prevalences for cigarette smoking, other combustible tobacco use, and smokeless tobacco use and prevalence odds ratios (PORs) for any tobacco product use among working adults at least 18 years of age, by industry and occupation. Of the estimated 144 million currently employed adults, 17% were cigarette smokers, 7.0% other noncigarette combustible tobacco users, and 3.4% smokeless tobacco users. Odds of using tobacco varied by sociodemographic characteristics and by industry and occupations. Disparities in tobacco use exist among working adults. Continued implementation of proven interventions to prevent and reduce all forms of tobacco use among U.S. workers is warranted, particularly among those workers with a higher burden of use.

  1. Tobacco Product Waste: An Environmental Approach to Reduce Tobacco Consumption.

    Cigarette butts and other tobacco product wastes (TPW) are the most common items picked up in urban and beach cleanups worldwide. TPW contains all the toxins, nicotine, and carcinogens found in tobacco products, along with the plastic nonbiodegradable filter attached to almost all cigarettes sold in the United States and in most countries worldwide. Toxicity studies suggest that compounds leached from cigarette butts in salt and fresh water are toxic to aquatic micro-organisms and test fish. Toxic chemicals have also been identified in roadside TPW. With as much as two-thirds of all smoked cigarettes (numbering in the trillions globally) being discarded into the environment each year, it is critical to consider the potential toxicity and remediation of these waste products. This article reviews reports on the toxicity of TPW and recommends several policy approaches to mitigation of this ubiquitous environmental blight.

    Despite significant declines in youth cigarette smoking, overall tobacco usage remains over 20% as non-cigarette tobacco product usage is increasingly common and polytobacco use (using 1+ tobacco product) remains steady. The present study was designed to identify patterns of youth tobacco use and examine associations with sociodemographic characteristics and tobacco dependence. The current analysis uses Latent Class Analysis (LCA) to examine the 6,958 tobacco users (n = 2,738 female) in the National Youth Tobacco Survey (2012 and 2013). We used as indicators past month use of tobacco products (cigarettes, cigars, smokeless tobacco, e-cigarettes, hookah, snus, pipes, bidis, and kreteks) and regressed resulting classes on sociodemographic characteristics and tobacco dependence. Nine classes emerged: cigarette smokers (33.4% of sample, also included small probabilities for use of cigars and e-cigarettes), cigar smokers (16.8%, nearly exclusive), smokeless tobacco users (12.3%, also included small probabilities for cigarettes, cigars, snus), hookah smokers (11.8%), tobacco smokers/chewers (10.7%, variety of primarily traditional tobacco products), tobacco/hookah smokers (7.2%), tobacco/snus/e-cig users (3.3%), e-cigarette users (2.9%,), and polytobacco users (1.7%, high probabilities for all products). Compared to cigarette smokers, tobacco/hookah smokers and hookah smokers were more likely to report Hispanic ethnicity. Polytobacco users were more likely to report dependence (AOR:2.77, 95% CI:[1.49-5.18]), whereas e-cigarette users were less likely (AOR:0.49, 95% CI:[0.24-0.97]). Findings are consistent with other research demonstrating shifts in adolescent tobacco product usage towards non-cigarette tobacco products. Continuous monitoring of these patterns is needed to help predict if this shift will ultimately result in improved public health.

    The growing involvement in Spain by civil society in the demand for tobacco control policies has been notable. The basis for the creation of the National Committee for Tobacco Prevention was established in 2004. At the end of that year, an intensive intervention was aimed at specifying, in law, the regulatory actions in the National Plan for Tobacco Prevention. This would facilitate a qualitative leap, taking advantage of the legal transposition of the European directive on advertising. With broad political consensus, the Law 28/2005 was established regarding sanitary measures for tobacco and the regulation of the sale, supply and consumption of tobacco products. The objective stated in this law is to prevent the initiation of tobacco consumption, especially among youth, guarantee the right of non-smokers to breathe air free from tobacco smoke and make quitting this habit easier for people who wish to do so. The main issues included are the prohibition of tobacco advertising and the limitation of tobacco consumption in common work areas and enclosed public spaces. The new law has replaced the previous rules in Spain, which were some of the most permissive in the European Union in terms of tobacco sales, advertising limitations and restrictions on smoking locations. It is clear that there is still much to be done. At this time, more social support needs to be generated in favor of the new regulations, and an important effort needs to be made to educate the public.

    A field plot experiment was conducted to investigate the tobacco yield and different forms of soil phosphorus under tobacco garlic crop rotation and intercropping patterns. The results showed that compared with tobacco monoculture, the tobacco yield and proportion of middle/high class of tobacco leaves to total leaves were significantly increased in tobacco garlic crop rotation and intercropping, and the rhizosphere soil available phosphorus contents were 1.3 and 1.7 times as high as that of tobacco monoculture at mature stage of lower leaf. For the inorganic phosphorus in rhizosphere and non-rhizosphere soil in different treatments, the contents of O-P and Fe-P were the highest, followed by Ca2-P and Al-P, and Ca8-P and Ca10-P were the lowest. Compared with tobacco monoculture and tobacco garlic crop intercropping, the Ca2-P concentration in rhizosphere soil under tobacco garlic crop rotation at mature stage of upper leaf, the Ca8-P concentration at mature stage of lower leaf, and the Ca10-P concentration at mature stage of middle leaf were lowest. The Al-P concentrations under tobacco garlic crop rotation and intercropping were 1.6 and 1.9 times, and 1.2 and 1.9 times as much as that under tobacco monoculture in rhizosphere soil at mature stages of lower leaf and middle leaf, respectively. The O-P concentrations in rhizosphere soil under tobacco garlic crop rotation and intercropping were significantly lower than that under tobacco monoculture. Compared with tobacco garlic crop intercropping, the tobacco garlic crop rotation could better improve tobacco yield and the proportion of high and middle class leaf by activating O-P, Ca10-P and resistant organic phosphorus in soil.

    We measured how student tobacco use and psychological risk factors (intention to use and perceived ease of access to tobacco products) were associated with tobacco vendor compliance with India's Cigarettes and Other Tobacco Products Act provisions regulating the point-of-sale (POS) environment. We conducted a population-based cross-sectional survey of high school students (n=1373) and tobacco vendors (n=436) in school-adjacent communities (n=26) in Mumbai, India. We used in-class self-administered questionnaires of high school students, face-to-face interviews with tobacco vendors and compliance checks of tobacco POS environments. Logistic regression models with adjustments for clustering were used to measure associations between student tobacco use, psychological risk factors and tobacco POS compliance. Compliance with POS laws was low overall and was associated with lower risk of student current tobacco use (OR 0.48, 95% CI 0.26 to 0.91) and current smokeless tobacco use (OR 0.40, 95% CI 0.21 to 0.77), when controlling for student-level and community-level tobacco use risk factors. Compliance was not associated with student intention to use tobacco (OR 0.50; 95% CI 0.21 to 1.18) and perceived ease of access to tobacco (OR 0.73; 95% CI 0.53 to 1.00). Improving vendor compliance with tobacco POS laws may reduce student tobacco use. Future studies should test strategies to improve compliance with tobacco POS laws, particularly in low-income and middle-income country settings like urban India. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    In 2013, the National Institutes of Health and the Food and Drug Administration funded a network of 14 Tobacco Centers of Regulatory Science (TCORS) with a mission that included research and training. A cross-TCORS Panel was established to define tobacco regulatory science (TRS) competencies to help harmonize and guide their emerging educational programs. The purpose of this paper is to describe the Panel's work to develop core TRS domains and competencies. The Panel developed the list of domains and competencies using a semistructured Delphi method divided into four phases occurring between November 2013 and August 2015. The final proposed list included a total of 51 competencies across six core domains and 28 competencies across five specialized domains. There is a need for continued discussion to establish the utility of the proposed set of competencies for emerging TRS curricula and to identify the best strategies for incorporating these competencies into TRS training programs. Given the field's broad multidisciplinary nature, further experience is needed to refine the core domains that should be covered in TRS training programs versus knowledge obtained in more specialized programs. Regulatory science to inform the regulation of tobacco products is an emerging field. The paper provides an initial list of core and specialized domains and competencies to be used in developing curricula for new and emerging training programs aimed at preparing a new cohort of scientists to conduct critical TRS research. © The Author 2016.

    Electronic cigarettes (e-cigarettes) have recently gained significant attention in the marketplace and in the media. However, limited information is available about the worldwide impact of e-cigarettes; most public health officials are calling for more data so they can more fully understand the potential risks and benefits of e-cigarettes in order to inform regulatory action. In the USA, e-cigarettes that are marketed as tobacco products are not currently regulated by the Food and Drug Admini...

  9. Analysis and control of excitation, field weakening and stability in direct torque controlled electrically excited synchronous motor drives

    Pyrhoenen, O

    1999-12-31

    Direct torque control (DTC) is a new control method for rotating field electrical machines. DTC controls directly the motor stator flux linkage with the stator voltage, and no stator current controllers are used. With the DTC method very good torque dynamics can be achieved. Until now, DTC has been applied to asynchronous motor drives. The purpose of this work is to analyse the applicability of DTC to electrically excited synchronous motor drives. Compared with asynchronous motor drives, electrically excited synchronous motor drives require an additional control for the rotor field current. The field current control is called excitation control in this study. The dependence of the static and dynamic performance of DTC synchronous motor drives on the excitation control has been analysed and a straightforward excitation control method has been developed and tested. In the field weakening range the stator flux linkage modulus must be reduced in order to keep the electro motive force of the synchronous motor smaller than the stator voltage and in order to maintain a sufficient voltage reserve. The dynamic performance of the DTC synchronous motor drive depends on the stator flux linkage modulus. Another important factor for the dynamic performance in the field weakening range is the excitation control. The field weakening analysis considers both dependencies. A modified excitation control method, which maximises the dynamic performance in the field weakening range, has been developed. In synchronous motor drives the load angle must be kept in a stabile working area in order to avoid loss of synchronism. The traditional vector control methods allow to adjust the load angle of the synchronous motor directly by the stator current control. In the DTC synchronous motor drive the load angle is not a directly controllable variable, but it is formed freely according to the motor`s electromagnetic state and load. The load angle can be limited indirectly by limiting the torque

    The presence of alpha and beta radionuclides in tobacco and tobacco products is a frequently discussed issue. However, any information in publications about them and their presence in tobacco products is too scarce. World Health care Organization monitors the influence of tobacco smoking on human health. In 2003, a Framework Convention on Tobacco Control was accepted with the aim to protect human health, which was signed by 179 countries, including Bulgaria. The first debates on the presence of radionuclides in tobacco products are raised in Moscow in 2014. These were instigated by data on the findings of polonium-210, reported by USA and Russia. The aim of the report is to outline a methodology to detect the presence of beta-active radionuclides in tobacco and its products. Keywords: beta activity, geiger counter, samples with infinite thickness, tobacco samples

    Worldwide, the burden of suffering to children caused by tobacco does not just originate from exposure to tobacco smoke or smoking, but includes exposure to tobacco-friendly media, poverty associated with money spent on tobacco, increased incidence of tobacco-related fires, and the harms related to child labor in tobacco cultivation. Despite global efforts through human rights acts, the Framework Convention on Tobacco Control, and the MPOWER report, tobacco use continues to accelerate in most countries. While the efforts that have been taken, such as smoking bans in public, are worthy actions, not enough is being done to protect children and teens. More can be done at the policy level, by individuals, and by health care providers. Copyright © 2011 Mosby, Inc. All rights reserved.

    Young, David; Coghill, Ken; Zhang, Jian Ying

    2010-01-01

    We use systems thinking to develop a strategic framework for analyzing the tobacco problem and we suggest solutions. Humans are vulnerable to nicotine addiction, and the most marketable form of nicotine delivery is the most harmful. A tobacco use management system has evolved out of governments’ attempts to regulate tobacco marketing and use and to support services that provide information about tobacco's harms and discourage its use. Our analysis identified 5 systemic problems that constrain progress toward the elimination of tobacco-related harm. We argue that this goal would be more readily achieved if the regulatory subsystem had dynamic power to regulate tobacco products and the tobacco industry as well as a responsive process for resourcing tobacco use control activities.

  1. A Behavioral Economics Perspective on Tobacco Taxation

    Science.gov (United States)

    2010-01-01

    Economic studies of taxation typically estimate external costs of tobacco use to be low and refrain from recommending large tobacco taxes. Behavioral economics suggests that a rational decision-making process by individuals fully aware of tobacco's hazards might still lead to overconsumption through the psychological tendency to favor immediate gratification over future harm. Taxes can serve as a self-control device to help reduce tobacco use and enable successful quit attempts. Whether taxes are appropriately high depends on how excessively people underrate the harm from tobacco use and varies with a country's circumstances. Such taxes are likely to be more equitable for poorer subgroups than traditional economic analysis suggests, which would strengthen the case for increased tobacco taxation globally. PMID:20220113

    Tobacco production, distribution, and use are international issues with significant health and economic implications. This paper provides an overview of the effective approaches to tobacco control including decreasing demand for tobacco products through taxation, consumer education, research, bans on advertising and promotion, warning labels, and restrictions on public smoking. The effectiveness of reducing the supply of tobacco products through prohibition, restrictions on youth access, crop substitution, trade restrictions, and control of smuggling, will also be discussed. Decreasing smoking, particularly among young people, by preventing or delaying initiation, preventing regular use, and increasing cessation through behavioural approaches for all ages is reviewed. Cessation methods including pharmacological approaches, 'quitlines', Internet programmes, and the targeting of specific populations are discussed. Internet availability of tobacco products and sustainability of current efforts are presented as continuing challenges to tobacco control.

    Lawrence, S

    2009-02-01

    Transnational tobacco companies (TTCs) considered Turkey an important, potential investment market because of its high consumption rates and domestic commitment to tobacco. This paper outlines how British American Tobacco (BAT) attempted to establish a joint venture with the government monopoly TEKEL, while waiting for privatisation and a private tender. Analysis of tobacco industry documents from the Guildford Depository and online tobacco document sources. BAT failed to establish a market share in Turkey until 2000 despite repeated attempts to form a joint venture with Turkey's tobacco monopoly, TEKEL, once the market liberalised in the mid 1980s. BAT's failure in the Turkish market was due to a misguided investment strategy focused solely on acquiring TEKEL and is contrasted with Philip Morris success in Turkey despite both TTCs working within Turkey's unstable and corrupt investing climate.

    The tobacco industry is a major political and legal force in Pennsylvania through campaign contributions, lobbying and litigation. The tobacco industry has become a major source of campaign contributions to legislative candidates, state constitutional office candidates, and political party committees. In the 1979-1980 election cycle, the tobacco industry contributed $3,600 to candidates and parties. In 1995-1996, the tobacco industry contributed $65,850 to candidates and parties. ...

  6. Military exceptionalism or tobacco exceptionalism: How civilian health leaders' beliefs may impede military tobacco control efforts

    Smoking impairs the readiness and performance of military personnel, yet congressional opposition has thwarted military tobacco control initiatives. Involvement of civilian organizations might alter this political dynamic. We interviewed 13 leaders of national civilian public health and tobacco control organizations to explore their perspectives on military tobacco control, inductively analyzing data for themes. Leaders believed that military tobacco use was problematic but lacked specific kn...

  7. Three-dimensional fracture instability of a displacement-weakening planar interface under locally peaked nonuniform loading

    We consider stability of fracture on a three-dimensional planar interface subjected to a loading stress that is locally peaked spatially, the level of which increases quasi-statically in time. Similar to the earlier study on the two-dimensional case (Uenishi and Rice, 2003; Rice and Uenishi, 2010), as the loading stress increases, a crack, or a region of displacement discontinuity (opening gap in tension or slip for shear fracture), develops on the interface where the stress is presumed to decrease according to a displacement-weakening constitutive relation. Upon reaching the instability point at which no further quasi-static solution for the extension of the crack on the interface exists, dynamic fracture follows. For the investigation of this instability point, we employ a dimensional analysis as well as an energy approach that gives a Rayleigh-Ritz approximation for the dependence of crack size and maximum displacement discontinuity on the level and quadratic shape of the loading stress distribution. We show that, if the linear displacement-weakening law is applied and the crack may be assumed of an elliptical form, the critical crack size at instability is independent of the curvature of the loading stress distribution and it is of the same order for all two- and three-dimensional cases.

    Understanding drivers of population fluctuation, especially for agricultural pests, is central to the provision of agro-ecosystem services. Here, we examine the role of endogenous density dependence and exogenous factors of climate and human activity in regulating the 37-year population dynamics of an important agricultural insect pest, the cotton bollworm (Helicoverpa armigera), in North China from 1975 to 2011. Quantitative time-series analysis provided strong evidence explaining long-term population dynamics of the cotton bollworm and its driving factors. Rising temperature and declining rainfall exacerbated the effect of agricultural intensification on continuously weakening the negative density dependence in regulating the population dynamics of cotton bollworms. Consequently, ongoing climate change and agricultural intensification unleashed the tightly regulated pest population and triggered the regional outbreak of H. armigera in 1992. Although the negative density dependence can effectively regulate the population change rate to fluctuate around zero at stable equilibrium levels before and after outbreak in the 1992, the population equilibrium jumped to a higher density level with apparently larger amplitudes after the outbreak. The results highlight the possibility for exogenous factors to induce pest outbreaks and alter the population regulating mechanism of negative density dependence and, thus, the stable equilibrium of the pest population, often to a higher level, posing considerable risks to the provision of agro-ecosystem services and regional food security. Efficient and timely measures of pest management in the era of Anthropocene should target the strengthening and revival of weakening density dependence caused by climate change and human activities.

  9. Sea level rise, surface warming, and the weakened buffering ability of South China Sea to strong typhoons in recent decades.

    Each year, a number of typhoons in the western North Pacific pass through the Luzon Strait into South China Sea (SCS). Although the storms remain above a warm open sea, the majority of them weaken due to atmospheric and oceanic environments unfavorable for typhoon intensification in SCS, which therefore serves as a natural buffer that shields the surrounding coasts from potentially more powerful storms. This study examines how this buffer has changed over inter-decadal and longer time scales. We show that the buffer weakens (i.e. greater potential for more powerful typhoons) in negative Pacific Decadal Oscillation (PDO) years, as well as with sea-level-rise and surface warming, caused primarily by the deepening of the ocean's 26 °C isotherm Z 26 . A new Intensity Change Index is proposed to describe the typhoon intensity change as a function of Z 26 and other environmental variables. In SCS, the new index accounts for as high as 75% of the total variance of typhoon intensity change.

  10. Income and Well-Being: Relative Income and Absolute Income Weaken Negative Emotion, but Only Relative Income Improves Positive Emotion.

    Whether relative income or absolute income could affect subjective well-being has been a bone of contention for years. Life satisfaction and the relative frequency of positive and negative emotions are parts of subjective well-being. According to the prospect theory, hedonic adaptation helps to explain why positive emotion is often so hard to be maintained, and negative emotion wouldn't be easy to be eliminated. So we expect the relationship between income and positive emotion is different from that between income and negative emotion. Given that regional reference is the main comparison mechanism, effects of regional average income on regional average subjective well-being should be potentially zero if only relative income matters. Using multilevel analysis, we tested the hypotheses with a dataset of 30,144 individuals from 162 counties in China. The results suggested that household income at the individual level is associated with life satisfaction, happiness and negative emotions. On the contrary, at a county level, household income is only associated with negative emotion. In other words, happiness and life satisfaction was only associated with relative income, but negative emotion was associated with relative income and absolute income. Without social comparison, income doesn't improve happiness, but it could weaken negative emotion. Therefore, it is possible for economic growth to weaken negative emotion without improving happiness. These findings also contribute to the current debate about the "Esterling paradox."

  11. The Hybridization Barrier between Herbaceous Medicago sativa and Woody M. arborea Is Weakened by Selection of Seed Parents

    2013-01-01

    Medicago sativa, alfalfa or lucerne, and M. arborea were considered reproductively isolated until recently. Then, in 2003, an alfalfa genotype was identified that produced a few seeds and progeny with hybrid traits after a large number of pollinations by M. arborea. A derivative of this alfalfa genotype also produced a low frequency of progeny with hybrid traits. Thus, the hybridization barrier was weakened by selection of seed parents. Hybrids from both events expressed traits from M. arborea and M. arborea-specific DNA bands, although more of the M. sativa genome was retained, based on the DNA results. Thus, there was chromatin elimination during embryogenesis, resulting in partial hybrids (hereafter hybrids). However, more than 30 hybrids with an array of M. arborea traits have been obtained thus far, and research continues on the nature of the hybrids. Traits have been genetically transmitted in crosses, and selected traits are in use for alfalfa breeding. This paper reviews the first hybrids and then focuses on further weakening of the hybridization barrier with the discovery of a more efficient hybridizer derived from crossing Medicago sativa subspecies, sativa, coerulea and falcata. This genotype was found to have reproductive abnormalities associated with its complex subspecies origin that are best described as hybrid breakdown. In effect, this subspecies derivative is a bridge-cross parent that consistently produces hybrids. Reproductive abnormalities in the bridge-cross parent are reported and discussed. PMID:27137379

    2016-05-01

    Variants of the Fagerström Tolerance Questionnaire and Fagerström Test for Nicotine Dependence (FTND) are widely used to study dependence among smokeless tobacco (ST) users. However, there is a need for a dependence measure which is based on the clinical definition of dependence and is easy to administer. The Tobacco Dependence Screener (TDS), a self-administered 10-item scale, is based on the Diagnostic and Statistical Manual, fourth edition (DSM-IV) and ICD-10 definitions of dependence. It is commonly used as a tobacco dependence screening tool in cigarette smoking studies but it has not been evaluated for dependence in ST users. The purpose of this study is to evaluate the TDS as a measure of tobacco dependence among ST users. Data collected from a community-based sample of exclusive ST users living in Oklahoma (n = 95) was used for this study. TDS was adapted to be used for ST dependence as the references for smoking were changed to ST use. Concurrent validity and reliability of TDS were evaluated. Salivary cotinine concentration was used as a criterion variable. Overall accuracy of the TDS was assessed by receiver's operating characteristic (ROC) curve and optimal cutoff scores for dependence diagnosis were evaluated. There was no floor or ceiling effect in TDS score (mean = 5.42, SD = 2.61). Concurrent validity of TDS as evaluated by comparing it with FTND-ST was affirmative. Study findings showed significant association between TDS and salivary cotinine concentration. The internal consistency assessed by Cronbach's alpha indicated that TDS had acceptable reliability (α = 0.765). TDS was negatively correlated with time to first chew/dip and positively correlated with frequency (number of chews per day) and years of ST use. Results of logistic regression analysis showed that at an optimal cutoff score of TDS 5+, ST users classified as dependent had significantly higher cotinine concentration and FTND-ST scores. TDS demonstrated acceptable reliability and

    Tobacco control must remain a critical global health priority given the growing burden of tobacco-induced disease in the developing world. Insights from the emerging field of global health delivery suggest that tobacco control could be improved through a systematic, granular analysis of the processes through which it is promoted, implemented, and combated. Using this framework, a critical bottleneck to the delivery of proven health promotion emerges in the role that the tobacco industry plays in promoting tobacco use and blocking effective tobacco-control policies. This "corporate bottleneck" can also be understood as a root cause of massive disease and suffering upon vulnerable populations worldwide, for the goal of maximizing corporate profit. Naming, understanding, and responding to this corporate bottleneck is crucial to the success of tobacco-control policies. Three case studies of tobacco-control policy--South Africa, the Framework Convention on Tobacco Control, and Uruguay--are presented to explore and understand the implications of this analysis. © 2011 Mount Sinai School of Medicine.

  15. Tobacco and the European common agricultural policy.

    Joossens, L; Raw, M

    1991-10-01

    The common agricultural policy of the European Community subsidizes tobacco production to the tune of 1,300 million ecu a year (US$ 1,500 million, UK pounds 900 million). This amounts to 2,500 ecu ($3,100, pounds 1,700) per minute, and is more in one year than the total amount spent on tobacco subsidies by the US in the last 50 years. The purpose of this policy was to maintain farmers' incomes and adapt community production to demand. Demand for the dark tobaccos which dominate EC production has fallen, while demand for light flue cured tobacco like Virginia has risen. A complex system of production subsidies and quotas was intended to discourage production of the dark tobaccos, for which there is virtually no market, and lead to more Virginia production. The policy has failed. Expenditure has spiralled out of control, production of unmarketable tobacco varieties has risen enormously, and the EC is the world's largest importer of raw tobacco. As a result tobacco is being bought by the community for intervention storage and surpluses of the dark high tar varieties are being 'exported' to eastern Europe and north Africa at giveaway prices. There has been no effective monitoring or control of this policy. This paper explains how this has happened and argues that, in view of the health risks attached to tobacco, these subsidies should be abolished.

  16. Advertising and promotion of smokeless tobacco products.

    Ernster, V L

    1989-01-01

    This paper is focused on the approaches used to advertise and promote smokeless tobacco products during the early to mid-1980s. These included traditional motifs that featured rugged-looking masculine models in sporting and outdoor settings as well as an expanded white-collar appeal. Smokeless tobacco was not affected by the ban on broadcast advertising of cigarettes that went into effect in 1971, and, until 1986, both print and broadcast media were used to advertise it. Promotional activities ranged from sponsorship of sporting events to offers for clothing bearing smokeless tobacco product logos. Despite the claims of manufacturers that advertising and promotional efforts were not targeted to youth, smokeless tobacco companies sponsored tobacco-spitting contests with teenage participants, a college marketing program, and college scholarships. In efforts that appeared designed to bolster their public image in the face of growing concern over the consequences of smokeless tobacco use by young people, companies like U.S. Tobacco Company contributed to major social programs, including, ironically, alcohol- and drug-abuse prevention programs. Spurred by public health groups, federal legislation was passed in 1986 that banned television and radio advertising of smokeless tobacco products and required manufacturers to include warning labels on their products on the potential health hazards of smokeless tobacco use.

    In adolescents aged 12-14, we measured attitudes to tobacco advertising. Our purpose is to understand the relation of these attitudes to tobacco use and identify the groups most influenced by the advertising. Survey of adolescents on Gran Canaria Island, Spain, about aspects of family, school, peers, tobacco consumption, and tobacco advertising. The subjects of the double-stratified cluster sample were 1910 students at the same grade level in 33 schools; 86.6% were 13 or 14 years old, and 51.2% were boys. We generated measures for attitudes to tobacco advertising from replies to seven questions with ordinal scales by an analysis of categorical principal components. To relate attitude to tobacco advertising and the profiles of these adolescents, we used multiple regression and logistic regression models. Attitudes to tobacco advertising are related to some home and school factors, but most significantly to tobacco and alcohol consumption, to amount of time at home without adults, and to peer influence. It is possible to draw up profiles of the students most vulnerable to tobacco advertising, and to cluster them in two groups, the "vitalists" and the "credulous." The effect of cigarette ads is different between these groups. This study can help to orientate smoking prevention.

    Assess the socioeconomic costs of smoking in Lebanon and understand the tobacco market and identify the winners and losers from the Lebanese tobacco trade. We take a close look at the market for tobacco and related markets to identify the main stakeholders and estimate the direct costs and benefits of tobacco. We also estimate lower bounds for the costs of tobacco, in terms of lost productivity, the cost of medical treatment, lost production due to premature death, and environmental damage. The paucity of data means our cost estimates are conservative lower bounds and we explicitly list the effects that we are unable to include. We identify the main actors in the tobacco trade: the Régie (the state-owned monopoly which regulates the tobacco trade), tobacco farmers, international tobacco companies, local distributors, retailers, consumers, and advertising firms. We identify as proximate actors the Ministries of Finance and Health, employers, and patients of smoking-related illnesses. In 2008, tobacco trade in Lebanon led to a total social cost of $326.7 million (1.1% of GDP). Low price tags on imported cigarettes not only increase smoking prevalence, but they also result in a net economic loss. Lebanese policymakers should consider the overall deficit from tobacco trade and implement the guidelines presented in the Framework Convention on Tobacco Control to at once increase government revenue and reduce government outlays, and save the labor market and the environment substantial costs.

    Tobacco content has been identified in popular video games played by adolescents. To date, there are no established instruments for categorizing tobacco content. We describe development and demonstrate the use of an instrument to categorize types of tobacco content. Interviews were conducted with 61 participants: 20 adolescents (mean age 17.7), and 41 adults (mean age 23.9), who discussed favorite games and recalled tobacco content. All games mentioned were examined for tobacco content by watching movies of game play on YouTube, examining individual game Wiki sites, and reviewing content descriptors provided by the Entertainment Software Rating Board (ESRB), Common Sense Media and the Internet Movie Database (IMDb). A typology of tobacco content was created and correlated with gamer recall of tobacco content. Participants together mentioned 366 games, of which 152 were unique. Tobacco content was verified in 39.5% (60/152) of games. Six categories of content were identified, including "no tobacco content." Of games containing tobacco, 88% (53/60) contained at least two categories of content. Games with more categories were associated with greater gamer recall of tobacco content. Tobacco content is present in video games and consciously recalled by players, with higher accuracy of recall associated with games featuring multiple types of tobacco content and more engaging, player-active content. Playing video games is now a daily part of most adolescents' lives. Tobacco content is present in many popular games. Currently there are no published instruments to assist in categorizing tobacco content in video games. This study describes a systematic approach to categorizing tobacco content in video games and demonstrates that games featuring more categories of tobacco content are associated with more accurate gamer recall of the presence of tobacco content when compared with games with fewer categories of content. Understanding the extent of such content will be essential

    2013-09-01

    Since the special tobacco tax was established in 1998, the tobacco tax and price of tobacco have increased thrice, in 2003, 2006, and 2010, respectively. We evaluated the effect of increases in tax on the consumption and sales of tobacco in Japan using the annual data on the number of tobacco products sold and the total sales from Japan Tobacco, Inc. We applied the number of tobacco products sold and the total sales per year to a joinpoint regression model to examine the trends in the data. This model could help identify the year in which a decrease or increase was apparent from the data. In addition, we examined the effect of each tax increase while also considering other factors that may have caused a decrease in the levels of tobacco consumption using the method proposed by Hirano et al. According to the joinpoint regression analysis, the number of tobacco products sold started decreasing in 1998, and the trends of decrease accelerated to 5% per year, from 2005. Owing to the tax increase, tobacco sales reduced by -2.4%, -2.9%, and -10.1% (corrected for the effect of the Tohoku Great Earthquake), and price elasticity was estimated as -0.30, -0.27, and -0.28 (corrected) in 2003, 2006, and 2010, respectively. The effect of tobacco tax increase on the decrease in tobacco sales was greatest in 2010, while the price elasticity remained almost the same as it was during the previous tax increase. The sharp hike in tobacco tax in 2010 decreased the number of tobacco products sold, while the price elasticity in 2010 was similar to that in 2003 and 2006. Our findings suggest that further increase in tobacco tax is needed to reduce the damage caused by smoking in the people of Japan.

    Female smoking is predicted to double between 2005 and 2025. There have been numerous calls for action on women's tobacco use over the past two decades. In the present work, evidence about female tobacco use, progress, challenges and ways forward for developing gendered tobacco control is reviewed. Literature on girls, women and tobacco was reviewed to identify trends and determinants of tobacco use and exposure, the application of gender analysis, tobacco marketing, the impact of tobacco control on girls and women and ways to address these issues particularly in low-income and middle-income countries. Global female tobacco use is increasingly complex, involving diverse products and factors including tobacco marketing, globalisation and changes in women's status. In high-income countries female smoking is declining but is increasingly concentrated among disadvantaged women. In low-income and middle-income countries the pattern is more complex; in several regions the gap between girls' and boys' smoking is narrow. Gendered analyses and approaches to tobacco control are uncommon, especially in low-income and middle-income countries. Tobacco control has remained largely gender blind, with little recognition of the importance of understanding the context and challenges of girl's and women's smoking and secondhand smoke exposure. There has been little integration of gender considerations in research, policy and programmes. The present work makes a case for gender and diversity analyses in tobacco control to reflect and identify intersecting factors affecting women's tobacco use. This will help animate the WHO Framework Convention on Tobacco Control's concern for gender specificity and women's leadership, and reduce the impact of tobacco on women.

  7. The plight of tobacco farming under hegemony of transnational tobacco companies in Turkey: repercussions and remedies

    Full Text Available Background The shift from State oversight to contractual farming mandated by law in 2002 as a structural adjustment conditionality has had destructive impact on Turkish tobacco agriculture: Transnational tobacco companies (TTCs gained control by being able to impose unilateral conditions; tobacco farmers were forced to face three options: prices below subsistence, migration, or turning to illicit market. A heated debate about illicit domestic tobacco market recently surfaced in news media. Methods (a Literature review, (b trend analysis of Turkish leaf tobacco output and trade as compared among 12 major tobacco growing countries, using official data (2003-2016, FAOstat (1961-2014, UNdata (1989-2015, (c review of relevant news coverage (2016 - June 2017. Results Over the last 25 years, Turkey was worst hit among the 12 countries: Leaf tobacco output dropped sharpest by 78%, and trade balance was drastically reversed. Between 2003-2016, cigarettes manufactured rose by 32.2%, leaf tobacco imports by 46.6%, whereas number of tobacco farmers declined by 82.4%, domestic output by 39.4%, and exports by 53.6%. Domestic tobacco used in cigarettes decreased from 42.1% to 13.3%. Tobacco agriculture vanished in certain regions or reduced to supplementary source of income undertaken by elderly and children. Domestic tobacco lobby seeks legalization, lower tax rates, and quotas for compulsory use of domestic tobacco in manufacturing. TTCs fervently oppose these positions and demand severe countermeasures. Conclusions TTCs ability to source leaf tobacco at lowest possible prices through their affiliates from around the world under liberalized trade and contractual farming regimes greatly harms agricultural activities realized by income and employment generating small family holdings, and thus national economies. In Turkey, TTC hegemony devastated farmers' livelihoods, caused market imbalance and duality, and disrupted regulations and taxation. Agriculture

    Tobacco-related content appears on social media in the form of advertising and messages by individuals. However, little is known about associations between posting social media messages and tobacco product use among adolescents and young adults. Self-reports of tobacco product use were obtained from the Children's Health Study of young adults in Southern California. Among the 1486 respondents in the most recent wave of the cohort (2016-2017), 284 provided tobacco product use data and their Twitter user names to access publicly available Twitter account data (mean age = 20.1 yrs. (SD = 0.6), 54% female, 49% Hispanic). We obtained the tweets that those respondents posted on Twitter, searched the tweets for 14 nicotine- and tobacco-related keywords, and coded these statements as positive or negative/neutral. Logistic regression analyses were conducted to determine whether respondents who posted positive tobacco-related tweets were more likely to report tobacco product use, relative to those who did not post any positive tobacco-related tweets. Respondents who posted any positive messages about tobacco had significantly higher odds of reporting past month use of cigarettes (OR = 3.15, 95% CI = 1.36, 7.30) and any tobacco product (OR = 2.41, 95% CI = 1.16, 5.01), relative to respondents who did not post about tobacco. This is the first study to establish an empirical link between adolescents' and young adults' tobacco-related Twitter activity and their tobacco product use. Health communications about the risks of tobacco use could target adolescents who post positive messages about tobacco products on Twitter. Copyright © 2018 Elsevier Inc. All rights reserved.

    Tobacco use is the leading cause of preventable disease and death in the United States. Increasing the unit price on tobacco products is the most effective tobacco prevention and control measure. Illicit tobacco trade (illicit trade) undermines high tobacco prices by providing tobacco users with cheaper-priced alternatives. In the United States, illicit trade primarily occurs when cigarettes are bought from states, jurisdictions, and federal reservation land with lower or no excise taxes, and sold in jurisdictions with higher taxes. Applying tax stamps to tobacco products, which provides documentation that taxes have been paid, is an important tool to combat illicit trade. Comprehensive tax stamping policy, which includes using digital, encrypted ("high-tech") stamps, applying stamps to all tobacco products, and working with tribes on stamping agreements, can further prevent and reduce illicit trade. This report describes state laws governing tax stamps on cigarettes, little cigars (cigarette-sized cigars), roll-your-own tobacco (RYOT), and tribal tobacco sales across the United States as of January 1, 2014, and assesses the extent of comprehensive tobacco tax stamping in the United States. Forty-four states (including the District of Columbia [DC]) applied traditional paper ("low-tech") tax stamps to cigarettes, whereas four authorized more effective high-tech stamps. Six states explicitly required stamps on other tobacco products (i.e., tobacco products other than cigarettes), and in approximately one third of states with tribal lands, tribes required tax stamping to address illicit purchases by nonmembers. No U.S. state had a comprehensive approach to tobacco tax stamping. Enhancing tobacco tax stamping across the country might further prevent and reduce illicit trade in the United States.

A two stage cluster sample design was used. SUDAAN and the C-sample procedure in Epi-Info was used for statistical analysis. Of the 2636 respondents, 71.8% (76.5% boys, 57.2% girls) were ever tobacco users; of them 48.9% had used tobacco before 10 years of age. Current use was reported by 58.9% (Boys 61.4%, Girls 51.2%); smokeless tobacco by 55.6% (Boys 57.6%, Girls 49.2%); and smoking by 19.4% (23.0% boys, 7.8% girls). Nearly one third (29%) students were exposed to ETS inside their homes and nearly half (48%) outside their homes. Almost all students reported watching cigarette and gutka advertisements in almost all kinds of media and events. Tobacco use by parents and friends, knowledge on harmful effects of chewing tobacco, smoking and environmental smoke, and attitudes on tobacco use by others were strongly associated with student tobacco use. Current tobacco use was reported significantly more by students who received pocket money/or were earning than by students who did not receive any pocket money/or did not earn (p value for trend <0.0001). Over half of current users (56%) bought their tobacco products from stores; of these, over 3/4th (77.2%) of them despite their age, had no difficulty in procuring these products. Teaching in schools regarding harmful effects of tobacco use was non-existent (3%). This urgently requires a comprehensive prevention program in schools and the community especially targeted towards girls.

  11. The fight against tobacco in developing countries.

    1994-02-01

    The battle to reduce the tobacco epidemic is not being won; the epidemic is merely being transferred from rich to poor countries. Tobacco-related mortality will rise from the present annual global toll of 3 million to over 10 million by the year 2025. Currently, most of these deaths are in developed countries but 7 out of the 10 million deaths will occur in developing countries by 2025. Developing countries cannot afford this increase, either in terms of human health or in economic costs, such as medical and health care costs, costs of lost productivity, costs of fires or costs of the misuse of land used to grow tobacco. As many of the tobacco-related illnesses, such as lung cancer or emphysema, are incurable even with expensive technology, the key to tobacco control lies in prevention. The essential elements of a national tobacco control policy are the same for all countries throughout the world--the only differences lie in fine tuning to a country's current situation. While indigenous production and consumption of tobacco remain a problem, of particular concern is the penetration of developing countries by the transnational tobacco companies, with aggressive promotional campaigns and the use of political and commercial pressures to open up markets and to promote foreign cigarettes. This includes specific targeting of women, few of whom currently smoke in developing countries. Also, tobacco advertising revenue prevents the media from reporting on the hazards of tobacco, a particularly serious problem in developing countries where awareness of the harmfulness of tobacco is low.(ABSTRACT TRUNCATED AT 250 WORDS)

    The China Tobacco Museum in Shanghai is the largest in China, consisting of seven pavilions of tobacco-related exhibits. A focus group and previous survey data revealed that the museum conveys messages that make tobacco use appealing. Of the pavilions, three were found to contain blatant misinformation about tobacco and tobacco consumption. We argue that the China Tobacco Museum is a platform for tobacco promotion, a form of tobacco advertising, promotion and sponsorship, and thus contravenes the FCTC.

    2018-03-01

    The Affordable Care Act (ACA) allowed employer plans in the small-group marketplace to charge tobacco users up to 50 percent more for premiums-known as tobacco surcharges-but only if the employer offered a tobacco cessation program and the employee in question failed to participate in it. Using 2016 survey data collected by the Henry J. Kaiser Family Foundation and Health Research and Educational Trust on 278 employers eligible for Small Business Health Options Program, we examined the prevalence of tobacco surcharges and tobacco cessation programs in the small-group market under this policy and found that 16.2 percent of small employers used tobacco surcharges. Overall, 47 percent of employers used tobacco surcharges but failed to offer tobacco cessation counseling. Wellness program prevalence was lower in states that allowed tobacco surcharges, and 10.8 percent of employers in these states were noncompliant with the ACA by charging tobacco users higher premiums without offering cessation programs. Efforts should be undertaken to improve the monitoring and enforcement of ACA tobacco rating rules.

    2017-03-01

    Japan Tobacco International (JTI) is the international division of Japan Tobacco Incorporated, and the world's third largest transnational tobacco company. Founded in 1999, JTI's rapid growth has been the result of a global business strategy that potentially serves as a model for other Asian tobacco companies. This paper analyses Japan Tobacco Incorporated's global expansion since the 1980s in response to market opening, foreign competition, and declining share of a contracting domestic market. Key features of its global strategy include the on-going central role and investment by the Japanese government, and an expansion agenda based on mergers and acquisitions. The paper also discusses the challenges this global business strategy poses for global tobacco control and public health. This paper is part of the special issue 'The Emergence of Asian Tobacco Companies: Implications for Global Health Governance'.

    The availability of the Children's Health Exposure Assessment Resource funded by the National Institute of Environmental Health Sciences provides new opportunities for exploring the role of tobacco smoke exposure in causing harm to children. Children of smokers are exposed to nicotine and other harmful tobacco smoke chemicals in utero as well as in their environment. This passive exposure to tobacco smoke has a variety of negative effects on children. In-utero exposure to tobacco smoke causes poor birth outcomes and influences lung, cardiovascular, and brain development, placing children at increased risk of a number of adverse health outcomes later in life, such as obesity, behavioral problems, and cardiovascular disease. Furthermore, most smokers start in their adolescence, an age of increased nicotine addiction risk. Biomarkers of tobacco exposure helps clarify the role tobacco chemicals play in influencing health both in childhood and beyond. Although electronic cigarettes (e-cigarettes) appear to be a nicotine delivery device of reduced harm, it appears to be a gateway to the use of combustible cigarette smoking in adolescents. Pediatric researchers interested in elucidating the role of tobacco smoke exposure in adverse outcomes in children should incorporate biomarkers of tobacco exposure in their studies.

    Tobacco-industry marketing has played a central part in the global spread of tobacco use and addiction. Although the absolute size of the tobacco market has dwindled, the industry is still immensely successful, largely due to sophisticated and manipulative marketing strategies. The UK tobacco industry identifies target groups and builds enduring relationships based on careful brand management. Potential customers are exposed to brands which are likely to appeal to them most. Tobacco companies tailor their products to target markets by altering the content of tar and nicotine, and by adding flavourings to produce a distinctive taste. Marketing strategies ensure that the products are promoted heavily at the point of sale, and directed advertising and sponsorship agreements are used to increase the visibility of the brand and strengthen its image. Tobacco companies also target non-consumer organisations such as retailers and policy makers with the aim of creating the best possible business environment for tobacco sales. We review published evidence, internal-advertising-agency documents, and observational data about tobacco promotion, and discuss the use of targeted marketing strategies in the UK.

    2011-01-01

    In order to study the non-uniformly transferring process of some tracer dosages, we assume that the absorption of some tracer by tobacco is a quadratic function of the tracer quantity of the tracer in the case of fast absorption, whereas the exclusion of the tracer from tobacco is a linear function of the tracer quantity in the case of slow exclusion, after the tracer is introduced into tobacco once at zero time. A single-compartment quadratic dynamical model of Logistic type is established for the leaves of tobacco. Then, a two-compartment quadratic dynamical model is established for leaves and calms of the tobacco. Qualitative analysis of the models shows that the tracer applied to the leaves of the tobacco is excluded finally; however, the tracer stays at the tobacco for finite time. Two methods are also given for computing the parameters in the models. Finally, the results of the models are verified by the 32 P experiment for the absorption of tobacco. (authors)

  10. Double elevator weakening for unilateral congenital superior oblique palsy with ipsilateral superior rectus contracture and lax superior oblique tendon.

    2012-06-01

    In unilateral congenital superior oblique palsy, a large hypertropia is sometimes associated with ipsilateral contracture of the superior rectus muscle and apparent overaction of the contralateral superior oblique. Ipsilateral double elevator weakening is one surgical approach; however, this procedure could compromise supraduction. We report a series of three consecutive patients who underwent ipsilateral superior rectus and inferior oblique recessions for unilateral superior oblique palsy. Intraoperatively, all three patients were found to have a lax ipsilateral superior oblique tendon. Postoperatively, all three patients had satisfactory correction of the hypertropia and abnormal head position with minimal supraduction defect. This procedure seems to be an acceptable initial surgical option for treating congenital superior oblique muscle palsy with ipsilateral contracture of the superior rectus muscle, even when the ipsilateral superior oblique tendon is lax.

    Tobacco use continues to be the leading global cause of preventable deaths, killing nearly 6 million people worldwide each year. Tobacco control must be given the high priority by scaling up tobacco control measures. In India under Control of Tobacco Product Act, it is mandatory to keep the warning labels over all kind of tobacco products in order to minimise the use of tobacco. Review of the knowledge regarding warning labels printed on tobacco products among its users and to evaluate the impact of them on addicting behaviour. A Cross Sectional study was carried out among the group of people using tobacco in any form. Total 776 tobacco users were enrolled in the study. Mean age of tobacco user was 41.4 years. Out of total 776 tobacco users, 561 (72.3%) had ever noticed warning signals over the tobacco products. Among those who have noticed warning labels, 64.4 % became aware about health effects and 66% have thought to quit tobacco. Tobacco users of young age group (15-45) were more aware regarding warning labels. Females were less aware. As level of education increases number of tobacco users who tried to quit or reduced the daily quantity of tobacco intake were also increases. Positive impact of warning labels has been seen among the tobacco users who have noticed them. Not all the tobacco users were aware regarding the presence of warning labels as per the findings of present study.

  14. Field- to nano-scale evidence for weakening mechanisms along the fault of the 2016 Amatrice and Norcia earthquakes, Italy

    2017-08-01

    In August and October 2016, two normal fault earthquakes (Mw 6.0 and Mw 6.5, respectively) struck the Amatrice-Norcia area in the central Apennines, Italy. The mainshocks nucleated at depths of 7-9 km with the co-seismic slip propagating upward along the Mt. Gorzano Fault (MGF) and Mt. Vettore Fault System (MVFS). To recognize possible weakening mechanisms along the carbonate-hosted seismogenic faults that generated the Amatrice-Norcia earthquakes, the fresh co-seismic fault exposure (i.e., "nastrino") exposed along the Mt. Vettoretto Fault was sampled and analyzed. This exposed fault belongs to the MVFS and was exhumed from 2-3 km depth. Over the fresh fault surface, phyllosilicates concentrated and localized along mm- to μm-thick layers, and truncated clasts and fluid-like structures were found. At the nano-scale, instead of their common platy-lamellar crystallographic texture, the analyzed phyllosilicates consist of welded nm-thick nanospherules and nanotubes similar to phyllosilicates deformed in rotary shear apparatus at seismic velocities or altered under high hydrothermal temperatures (> 250 °C). Moreover, the attitude of the Mt. Vettoretto Fault and its kinematics inferred from exposed slickenlines are consistent with the co-seismic fault and slip vectors obtained from the focal mechanisms computed for the 2016 mainshocks. All these pieces of evidence suggest that the Mt. Vettoretto Fault slipped seismically during past earthquakes and that co-seismic slip was assisted and facilitated at depths of synoptic picture of co-seismic processes and weakening mechanisms that may occur in carbonate-hosted seismogenic faults.

  15. Involvement of reactive oxygen species in endosperm cap weakening and embryo elongation growth during lettuce seed germination

    Endosperm cap (CAP) weakening and embryo elongation growth are prerequisites for the completion of lettuce seed germination. Although it has been proposed that the cell wall loosening underlying these processes results from an enzymatic mechanism, it is still unclear which enzymes are involved. Here it is shown that reactive oxygen species (ROS), which are non-enzymatic factors, may be involved in the two processes. In Guasihong lettuce seeds imbibed in water, O2·– and H2O2 accumulated and peroxidase activity increased in the CAP, whereas its puncture force decreased. In addition, in the radicle, the increase in embryo growth potential was accompanied by accumulation of O2·– and an increase in peroxidase activity. Imbibing seeds in 0.3% sodium dichloroisocyanurate (SDIC) reduced endosperm viability and the levels of O2·–, H2O2, and peroxidase activity in the CAP, whereas the decrease in its puncture force was inhibited. However, in the embryo, SDIC did not affect the accumulation of O2·–, peroxidase activity, and the embryo growth potential. As a result, SDIC caused atypical germination, in which the endosperm ruptured at the boundary between the CAP and lateral endosperm. ROS scavengers and ROS generation inhibitors inhibited the CAP weakening and also decreased the embryo growth potential, thus decreasing the percentage of seed germination. Exogenous ROS and ROS generation inducers increased the percentage of CAP rupture to some extent, and the addition of H2O2 to 0.3% SDIC enabled some seeds to undergo typical germination.

    Memory is lost by the increased influx of extracellular Zn 2+ into neurons. It is possible that intracellular Zn 2+ dynamics is modified even at non-zincergic medial perforant pathway-dentate granule cell synapses along with aging and that vulnerability to the modification is linked to age-related cognitive decline. To examine these possibilities, vulnerability of long-term potentiation (LTP) maintenance, which underlies memory retention, to modification of synaptic Zn 2+ dynamics was compared between young and aged rats. The influx of extracellular Zn 2+ into dentate granule cells was increased in aged rats after injection of high K + into the dentate gyrus, but not in young rats. This increase impaired maintained LTP in aged rats. However, the impairment was rescued by co-injection of CaEDTA, an extracellular Zn 2+ chelator, or CNQX, an AMPA receptor antagonist, which suppressed the Zn 2+ influx. Maintained LTP was also impaired in aged rats after injection of ZnAF-2DA into the dentate gyrus that chelates intracellular Zn 2+ , but not in young rats. Interestingly, the capacity of chelating intracellular Zn 2+ with intracellular ZnAF-2 was almost lost in the aged dentate gyrus 2 h after injection of ZnAF-2DA into the dentate gyrus, suggesting that intracellular Zn 2+ -buffering is weakened in the aged dentate gyrus, compared to the young dentate gyrus. In the dentate gyrus of aged rats, maintained LTP is more vulnerable to modification of intracellular Zn 2+ dynamics than in young rats, probably due to weakened intracellular Zn 2+ -buffering.

    Electronic cigarettes (e-cigarettes) have recently gained significant attention in the marketplace and in the media. However, limited information is available about the worldwide impact of e-cigarettes; most public health officials are calling for more data so they can more fully understand the potential risks and benefits of e-cigarettes in order to inform regulatory action. In the USA, e-cigarettes that are marketed as tobacco products are not currently regulated by the Food and Drug Administration (FDA). However, having a continuum of nicotine-containing products that cross jurisdictional lines within the FDA in the future would create the potential (and the need) for a comprehensive nicotine strategy at the FDA. As part of developing the most appropriate approach to e-cigarette regulation, FDA Center for Tobacco Products scientists have been reviewing the available literature to determine the state of e-cigarette knowledge and have identified research areas that could be addressed. This supplement provides a summary of the current knowledge and research gaps pertaining to e-cigarettes with regards to product design, chemistry and toxicology of e-liquid and aerosol constituents, human factor-based risk factors, abuse liability, clinical pharmacology and human health effects, paediatric issues, and environmental issues.

  18. From cigarette smuggling to illicit tobacco trade.

    2012-03-01

    Tax policy is considered the most effective strategy to reduce tobacco consumption and prevalence. Tax avoidance and tax evasion therefore undermine the effectiveness of tax policies and result in less revenue for governments, cheaper prices for smokers and increased tobacco use. Tobacco smuggling and illicit tobacco trade have probably always existed, since tobacco's introduction as a valuable product from the New World, but the nature of the trade has changed. This article clarifies definitions, reviews the key issues related to illicit trade, describes the different ways taxes are circumvented and looks at the size of the problem, its changing nature and its causes. The difficulties of data collection and research are discussed. Finally, we look at the policy options to combat illicit trade and the negotiations for a WHO Framework Convention on Tobacco Control (FCTC) protocol on illicit tobacco trade. Twenty years ago the main type of illicit trade was large-scale cigarette smuggling of well known cigarette brands. A change occurred as some major international tobacco companies in Europe and the Americas reviewed their export practices due to tax regulations, investigations and lawsuits by the authorities. Other types of illicit trade emerged such as illegal manufacturing, including counterfeiting and the emergence of new cigarette brands, produced in a rather open manner at well known locations, which are only or mainly intended for the illegal market of another country. The global scope and multifaceted nature of the illicit tobacco trade requires a coordinated international response, so a strong protocol to the FCTC is essential. The illicit tobacco trade is a global problem which needs a global solution.

    Background/aim Argentina has one of the highest cigarette smoking rates among both men and women in the Americas and no legislated restrictions on tobacco industry advertising. The tobacco industry has traditionally expanded markets by targeting adolescents and young adults. The objective of this study was to determine whether and how the tobacco industry promotes cigarettes to adolescents in Argentina. Methods We conducted a systematic search of tobacco industry documents available through the internet dated between 1995 and 2004 using standard search terms to identify marketing strategies in Argentina. A selected review of the four leading newspapers and nine magazines with reported high readership among adolescents was completed. The selected print media were searched for tobacco images and these were classified as advertisements if associated with a commercial product or as a story if not. Results The tobacco industry used market segmentation as a strategy to target Argentinean consumers. British American Tobacco (BAT) undertook a young adult psychographic study and classified them as “progressives”, “Jurassics” or “conservatives” and “crudos” or “spoiled brats”. BAT marketed Lucky Strike to the “progressives” using Hollywood movies as a vehicle. The tobacco industry also targeted their national brands to the conservatives and linked these brands with “nationalistic values” in advertising campaigns. Philip Morris promoted Marlboro by sponsoring activities directed at young people and they launched the 10 cigarettes packet as a starter vehicle. Conclusions The tobacco industry used psychographic segmentation of the population and developed advertising strategies focused on youth. Tobacco control researchers and advocates must be able to address these strategies in counter-marketing interventions. PMID:18299308

    Objectives. We assessed the prevalence and sociodemographic correlates of tobacco use among US adults. Methods. We used data from the 2009–2010 National Adult Tobacco Survey, a national landline and cell phone survey of adults aged 18 years and older, to estimate current use of any tobacco; cigarettes; cigars, cigarillos, or small cigars; chewing tobacco, snuff, or dip; water pipes; snus; and pipes. We stratified estimates by gender, age, race/ethnicity, education, income, sexual orientation, and US state. Results. National prevalence of current use was 25.2% for any tobacco; 19.5% for cigarettes; 6.6% for cigars, cigarillos, or small cigars; 3.4% for chewing tobacco, snuff, or dip; 1.5% for water pipes; 1.4% for snus; and 1.1% for pipes. Tobacco use was greatest among respondents who were male, younger, of non-Hispanic “other” race/ethnicity, less educated, less wealthy, and lesbian, gay, bisexual, or transgender. Prevalence ranged from 14.1% (Utah) to 37.4% (Kentucky). Conclusions. Tobacco use varies by geography and sociodemographic factors, but remains prevalent among US adults. Evidence-based prevention strategies are needed to decrease tobacco use and the health and economic burden of tobacco-related diseases. PMID:22994278

  1. Role of Oxides of Nitrogen in Tobacco-Specific Nitrosamine Formation in Flue-Cured Tobacco

    Full Text Available Tobacco is known to contain a class of nitrosamines known as tobacco-specific nitrosamines or TSNA. Nitrosation of naturally occurring tobacco alkaloids is commonly accepted as the mechanism of TSNA formation in tobacco. Because green and freshly harvested tobaccos are virtually free of TSNA, formation and accumulation of TSNA are generally considered to occur during the curing process. Most recent hypotheses have focused on microbial reduction of nitrate to nitrite and other oxides of nitrogen (NOcompounds that react with tobacco alkaloids to form TSNA during curing. This natural microbial process remains the prevalent hypothesis for TSNA formation in burley and other air-cured tobaccos. However, a different mechanism for the formation of TSNA in flue-cured tobacco, independent of microbial activity, is documented in this paper. It is common practice to flue-cure Virginia or blonde tobacco in bulk barns that incorporate forced air ventilation and temperature control. For the last thirty-five years, many modern bulk barns in North America generally have used liquid propane gas (LPG with direct-fired burners that exhaust combustion gases directly into the barn where the tobacco is exposed to those gases. Our studies indicate that LPG combustion by-products in the exhaust stream, namely NO, react with naturally occurring tobacco alkaloids to form TSNA. Heat exchange curing methods preclude exposure of the tobacco to combustion gases and by-products, thereby eliminating this significant source of TSNA formation, without degrading leaf quality or smoking character. Research findings from 1998 and 1999 are presented to demonstrate the role of NOgases in TSNA formation and the significance of direct-fired curing as a primary source of TSNA formation in flue-cured tobacco. Also, data from an extensive barn conversion program in 2000, which resulted in a 94% average reduction in TSNA levels in cured flue-cured leaf, are presented.

    With a long history of tobacco cultivation, adolescents in Ghana are at relatively high risk of the emerging tobacco epidemic in developing countries. This study explored exposure to tobacco promoting/restraining factors and their associations with smoking and tawa (traditional smokeless tobacco) use among 13-18-year-old Ghanaians. School-based representative data were collected in 2008 (n = 1165). Prevalence rates of tobacco use, smoking and tawa use were 9.1% (11.5% boys and 6.4% girls), 6.6% (8.0% boys and 4.7% girls) and 5.7% (7.3% boys and 3.9% girls), respectively. Four percent of the respondents attended schools without a smoking ban, 66% had been taught about the harmful effects of smoking in the current school year, and 53% had been exposed to tobacco advertising. Fifty-three percent of adolescents who had tried to purchase tobacco products were not refused because of their age. Multivariate analyses found that attendance at a school where smoking was allowed, not having been taught about the harmful effects of smoking, exposure to tobacco advertising and parental smoking were positively associated with tobacco use, and knowledge that smoking is harmful to health and difficult to quit were negatively associated with tobacco use. Both smoking and tawa use were relatively low among Ghanaian adolescents. Exposure to tobacco advertising was high. There is no tobacco legislation in Ghana, but societal norms or cultural values seem to restrict smoking in schools and access to tobacco products.

    Background A growing body of evidence suggests that tobacco dependence symptoms can occur soon after smoking onset and with low levels of use. However, limited data are available nationally and among non-cigarette tobacco users. Purpose To examine the prevalence and determinants of tobacco dependence symptoms among adolescent tobacco users in the 2012 National Youth Tobacco Survey, a nationally representative, school-based survey of U.S. middle and high school students. Methods Multivariate logistic regression was used to identify independent predictors of dependence symptoms among current users (i.e., past 30-day use) of cigarettes, cigars, or smokeless tobacco. Analyses were conducted in 2013 using SAS-callable SUDAAN, version 11 to account for the complex survey design. Results Prevalence of tobacco dependence symptoms ranged from 20.8% (95% CI=18.6, 23.1) of current tobacco users reporting wanting to use tobacco within 30 minutes of waking to 41.9% (95% CI=39.3, 44.5) reporting recent strong cravings. Reporting of dependence symptoms was most consistently associated with polytobacco use, higher frequency of use, earlier initiation age, and female gender. A 2–4-fold increase in the odds of symptom reporting was found in adolescents using tobacco products on as few as 3–5 days compared to those who only used it for 1–2 of the past 30 days. Conclusions A substantial proportion of U.S. adolescent tobacco users, including those with low levels of use, report symptoms of tobacco dependence. These findings demonstrate the need for full implementation of evidence-based strategies to prevent both experimentation and progression to regular tobacco use among youth. PMID:25044195

    The Diagnostic and statistical manual of mental disorders, third edition (DSM-III), published by the American Psychiatric Association (APA) in 1980, included the first official definitions by the APA of tobacco dependence and tobacco withdrawal. Tobacco industry efforts to influence the DSM-III were investigated. Searches of previously secret tobacco industry documents, primarily the University of California San Francisco Legacy Tobacco Documents Library and British American Tobacco collections. Additional information was collected through discussions with editors of DSM-III, and library and general internet searches. The tobacco companies regarded the inclusion of tobacco dependence as a diagnosis in DSM-III as an adverse event. It worked to influence the content of the DSM-III and its impact following publication. These efforts included public statements and private lobbying of DSM-III editors and high ranking APA officers by prominent US psychiatrists with undisclosed ties to the tobacco industry. Following publication of DSM-III, tobacco companies contracted with two US professors of psychiatry to organise a conference and publish a monograph detailing controversies surrounding DSM-III. The tobacco industry and its allies lobbied to narrow the definition of tobacco dependence in serial revisions of DSM-III. Following publication of DSM-III, the industry took steps to try to mitigate its impact. These actions mirror industry tactics to influence medical research and policy in various contexts worldwide. Such tactics slow the spread of a professional and public understanding of smoking and health that otherwise would reduce smoking, smoking induced disease, and tobacco company profits.

    To understand transnational tobacco companies' (TTCs) practices in low and middle-income countries which serve to block tobacco-control policies and promote tobacco use. Systematic review of published research on tobacco industry activities to promote tobacco use and oppose tobacco-control policies in low and middle-income countries. TTCs' strategies used in low and middle-income countries followed four main themes-economic activity; marketing/promotion; political activity; and deceptive/manipulative activity. Economic activity, including foreign investment and smuggling, was used to enter new markets. Political activities included lobbying, offering voluntary self-regulatory codes, and mounting corporate social responsibility campaigns. Deceptive activities included manipulation of science and use of third-party allies to oppose smoke-free policies, delay other tobacco-control policies, and maintain support of policymakers and the public for a pro-tobacco industry policy environment. TTCs used tactics for marketing, advertising, and promoting their brands that were tailored to specific market environments. These activities included direct and indirect tactis, targeting particular populations, and introducing new tobacco products designed to limit marketing restrictions and taxes, maintain the social acceptability of tobacco use, and counter tobacco-control efforts. TTCs have used similar strategies in high-income countries as these being described in low and middle-income countries. As required by FCTC Article 5.3, to counter tobacco industry pressures and to implement effective tobacco-control policies, governments and health professionals in low and middle-income countries should fully understand TTCs practices and counter them.

    Full Text Available Background: Long-term adverse cardiovascular effects of smokeless tobacco are well established, however, the effect of chewing tobacco on coronary microcirculation and hemodynamic have not been studied. We intended to analyze the acute effect of chewing tobacco on coronary microcirculation and hemodynamics in habitual tobacco chewers with stable coronary artery disease undergoing elective percutaneous coronary intervention (PCI. Materials and Methods: We prospectively enrolled seven habitual tobacco chewers with stable coronary artery disease with single vessel disease or double vessel disease satisfying the criteria for elective PCI. Patients were instructed to keep 1 g of crushed dried tobacco leaves in the mouth after a successful PCI. Lesion in last stented vessels was evaluated for fractional flow reserve (FFR, coronary flow reserve (CFR, and index of microcirculatory resistance (IMR post-PCI, after 15 min and 30 min of tobacco chewing along with the measurement of serum cotinine levels. Results: Oral tobacco led to high levels of cotinine in the majority of patients. There was an insignificant rise in heart rate, systolic and diastolic blood pressure following tobacco consumption. Baseline CFR (median 1.6, range 1.1–5.5 was low in tobacco chewers after PCI even after optimum FFR (0.9 ± 0.05 in the majority of patients suggesting abnormal microvascular hemodynamics (high IMR in 3 patients, overall median 14.2, range 7–36.2. However, there was no significant change in the estimated CFR or IMR values following tobacco chewing. One patient had bradycardia and hypotension which may be related to vagal reaction or acute nicotine poisoning. Conclusion: Tobacco chewers have abnormal coronary microcirculation hemodynamics even following a successful PCI. However, the coronary micocirculation and hemodynamics do not change acutely following tobacco chewing despite high serum cotinine concentrations.

    One of the strategies to control tobacco is to limit purchase of cigarettes to minors. To understand the attitudes of Italian adults towards regulations to prevent minors from purchasing tobacco products, we added specific questions to the annual survey on smoking in Italy. During March-April 2007, we conducted a survey on smoking on 3,057 subjects representative of the Italian population aged > or = 15 years. Two specific questions were included, one investigating the attitudes towards the proposed legislation prohibiting purchase of tobacco to individuals under 18 years of age (instead of 16 years) as a policy to reduce smoking prevalence and consumption. The second question asked whether the current tobacco sales-to-minors law was observed. Overall, 78% of Italians believed that a restriction of the current tobacco sales-to-minors law could be moderately to extremely effective as a strategy to decrease smoking prevalence and consumption. More than 90% of Italians reported that they had never seen in their lifetime a retailer refusing to sell cigarettes to an adolescent or requesting the minor's identification or age. A restriction of the legislation, increasing to 18 years the minimum age for purchasing tobacco, would limit access to tobacco products by minors, only if adopted together with systematic and effective enforcement measures.

    2010-01-01

    This paper describes research designs and statistical analyses to investigate how tobacco prevention programs achieve their effects on tobacco use. A theoretical approach to program development and evaluation useful for any prevention program guides the analysis. The theoretical approach focuses on action theory for how the program affects mediating variables and on conceptual theory for how mediating variables are related to tobacco use. Information on the mediating mechanisms by which tobacco prevention programs achieve effects is useful for the development of efficient programs and provides a test of the theoretical basis of prevention efforts. Examples of these potential mediating mechanisms are described including mediated effects through attitudes, social norms, beliefs about positive consequences, and accessibility to tobacco. Prior research provides evidence that changes in social norms are a critical mediating mechanism for successful tobacco prevention. Analysis of mediating variables in single group designs with multiple mediators are described as well as multiple group randomized designs which are the most likely to accurately uncover important mediating mechanisms. More complicated dismantling and constructive designs are described and illustrated based on current findings from tobacco research. Mediation analysis for categorical outcomes and more complicated statistical methods are outlined. PMID:12324176

    Advertising plays a major role in smoking behavior and forming brand preferences. Additionally, the most advertised tobacco brands have also been the most preferred. Maintaining brand loyalty in Latin America remains a priority for the tobacco industry. The purpose of this study was to explore tobacco brand preference trends from 2003 to 2006, and explore marketing and advertising factors that might be associated with these trends. Data for this study came from Mexican adolescents residing in cities that participated in the Global Youth Tobacco Survey in both 2003 and 2006 and reported smoking either Marlboro or Camel cigarettes in the past 30 days. Respondents reported the brand name of their preferred cigarette during the past 30 days. Multivariate regression analysis was used to determine differences by brand preference and exposure to tobacco marketing and advertising, which was assessed using six items. In 2003, most adolescents preferred Marlboro. By 2006, older boys preferred Camel cigarettes to Marlboro, while girls' preference for Camel was similar to their preference for Marlboro. Adolescents that preferred Camel cigarettes in 2003 also reported greater exposure to tobacco marketing and advertising. Findings indicate that there are ongoing shifts in youth brand preference in Mexico, and that these shifts might be related to marketing and advertising practices. There is an ongoing need for monitoring marketing and advertising practices in an effort to protect adolescents from tobacco company exploits.

    During the 20th century, use of tobacco products contributed to the deaths of 100 million persons worldwide. In 2011, approximately 6 million additional deaths were linked to tobacco use, the world's leading underlying cause of death, responsible for more deaths each year than human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), tuberculosis, and malaria combined. One third to one half of lifetime users die from tobacco products, and smokers die an average of 14 years earlier than nonsmokers. Manufactured cigarettes account for 96% of all tobacco sales worldwide. From 1880 to 2009, annual global consumption of cigarettes increased from an estimated 10 billion cigarettes to approximately 5.9 trillion cigarettes, with five countries accounting for 58% of the total consumption: China (38%), Russia (7%), the United States (5%), Indonesia (4%), and Japan (4%). Among the estimated 1 billion smokers worldwide, men outnumber women by four to one. In 14 countries, at least 50% of men smoke, whereas in more than half of these same countries, fewer than 10% of women smoke. If current trends persist, an estimated 500 million persons alive today will die from use of tobacco products. By 2030, tobacco use will result in the deaths of approximately 8 million persons worldwide each year. Yet, every death from tobacco products is preventable.

    Tobacco companies are utilizing similar strategies to advertise and promote their products in developing countries as they have used successfully for over 50 years in developed countries. The present study describes how adult smokers, smokeless tobacco users, and non-users of tobacco from the Tobacco Control Project (TCP) India Pilot Survey, conducted in 2006, responded to questions regarding their perceptions and observations of pro-tobacco advertising and promotion and beliefs about tobacco use. Analyses found that 74% (n=562) of respondents reported seeing some form of pro-tobacco advertising in the last six months, with no differences observed between smokers (74%), smokeless tobacco users (74%), and nonsmokers (73%). More than half of respondents reported seeing pro-tobacco advertising on store windows or inside shops. Overall, this study found that a significant percentage of tobacco users and non-users in India report seeing some form of pro-tobacco advertising and promotion messages. Additional analyses found that smokers were more likely to perceive tobacco use as harmful to their health compared with smokeless tobacco users and non-users (padvertising and promotion of tobacco products in India.

  13. Effect of smokeless tobacco product marketing and use on population harm from tobacco use policy perspective for tobacco-risk reduction.

    Kozlowski, Lynn T

    2007-12-01

    This article presents policy perspectives on the marketing of smokeless tobacco products to reduce population harm from tobacco use. Despite consensus that smokeless tobacco products as sold in the United States are less dangerous than cigarettes, there is no consensus on how to proceed. Diverse factions have different policy concerns. While the tobacco industry is exempted from U.S. Food and Drug Administration (FDA) oversight, the pharmaceutical industry whose nicotine replacement therapy (NRT) medicines compete with smokeless tobacco as noncombustible nicotine-delivery systems are regulated by the FDA. Some public health experts support smokeless tobacco use to reduce population harm from tobacco; other public health experts oppose promoting smokeless tobacco for harm reduction. Adult consumers can freely purchase currently-marketed smokeless tobacco products and even more-deadly cigarettes. Concerns with and advantages of smokeless tobacco products are discussed. In that noncombustible medicinal nicotine-delivery systems have been proven to be effective smoking-cessation aids, smokeless tobacco, as another source of psychoactive doses of nicotine, could be used similarly, in a dose-response fashion as a smoking-cessation aid (consistent with FDA principles for evaluating generic versions of drugs). Price measures should be used on tobacco products to make costs to consumers proportional to product health risks (which would make smokeless tobacco much cheaper than cigarettes), and smokeless tobacco should be encouraged as an option for smoking cessation in adult smokers, particularly for those who have failed to stop smoking using NRT or other methods.

    Background: Alcohol and tobacco abuse are detrimental to general and oral health. Though the effects of these harmful habits on oral mucosa had been demonstrated, their independent and combined effect on the dental caries experience is unknown and worthy of investigation. Materials and Methods: We compared 268 alcohol-only abusers with 2426 alcohol and tobacco abusers in chewing and smoking forms to test the hypothesis that various components of their dental caries experience are significantly different due to plausible sociobiological explanations. Clinical examination, Decay, Missing, Filled Teeth (DMFT) Index and Oral Hygiene Index - Simplified were measured in a predetermined format. Descriptive statistics, Chi-square test and one-way ANOVA analysis were done using SPSS Version 16.0. Result: The mean DMFT were 3.31, 3.24, 4.09, 2.89 for alcohol-only abusers, alcohol and chewing tobacco abusers, smoking tobacco and alcohol abusers, and those who abused tobacco in smoke and smokeless forms respectively. There was no significant difference between the oral hygiene care measures between the study groups. Presence of attrition among chewers and those with extrinsic stains experienced less caries than others. Discussion and conclusion: The entire study population exhibited a higher incidence of caries experience. Use of tobacco in any form appears to substantially increase the risk for dental caries. Attrition with use of chewing tobacco and presence of extrinsic stains with tobacco use appear to provide a protective effect from caries. The changes in oral micro-flora owing to tobacco use and alcohol may play a critical role in the initiation and progression of dental caries. PMID:21731272

    Smokeless tobacco (snuff) is a finely ground or shredded tobacco that is sniffed through the nose or placed between the cheek and gum. Chewing tobacco is used by putting a wad of tobacco inside the cheek. Smokeless tobacco is widely used by young athletes to enhance performance because nicotine improves some aspects of physiology. However, smokeless tobacco has harmful health effects, including cardiovascular disorders, linked to nicotine physiological effects, mainly through catecholamine release. Nicotine decreases heart rate variability and the ventricular fibrillation threshold, and promotes the occurrence of various arrhythmias; it also impairs endothelial-dependent vasodilation and could therefore promote premature atherogenesis. At rest, heart rate, blood pressure, inotropism, cardiac output and myocardial oxygen consumption are increased by nicotine, leading to an imbalance between myocardial oxygen demand and supply. The same occurs at submaximal levels of exercise. These increases are accompanied by a rise in systemic resistances. At maximal exercise, heart rate, cardiac output and maximal oxygen uptake (V˙O2max) are unaffected by nicotine. Because endothelial dysfunction is promoted by nicotine, paradoxical coronary vasoconstriction may occur during exercise and recovery. Nicotine induces a decrease in muscular strength and impairs anaerobic performance. However, nicotine is used in sports as it diminishes anxiety, enhances concentration and agility, improves aerobic performance and favours weight control. Importantly, smokeless tobacco, similar to cigarette smoking, leads to nicotine dependence through dopaminergic pathways. Smokeless tobacco has harmful cardiovascular effects and is addictive: it fulfils all the criteria for inclusion in the World Anti-Doping Agency prohibited list as a doping product. Smokeless tobacco use in sporting activities must be discouraged. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    This study examined whether a policy of banning tobacco product retailers from operating within 1000 feet of schools could reduce existing socioeconomic and racial/ethnic disparities in tobacco retailer density. We geocoded all tobacco retailers in Missouri (n = 4730) and New York (n = 17 672) and linked them with Census tract characteristics. We then tested the potential impact of a proximity policy that would ban retailers from selling tobacco products within 1000 feet of schools. Our results confirmed socioeconomic and racial/ethnic disparities in tobacco retailer density, with more retailers found in areas with lower income and greater proportions of African American residents. A high proportion of retailers located in these areas were in urban areas, which also have stores located in closer proximity to schools. If a ban on tobacco product sales within 1000 feet of schools were implemented in New York, the number of tobacco retailers per 1000 people would go from 1.28 to 0.36 in the lowest income quintile, and from 0.84 to 0.45 in the highest income quintile. In New York and Missouri, a ban on tobacco product sales near schools would either reduce or eliminate existing disparities in tobacco retailer density by income level and by proportion of African American. Proximity-based point of sale (POS) policies banning tobacco product sales near schools appear to be more effective in reducing retailer density in lower income and racially diverse neighborhoods than in higher income and white neighborhoods, and hold great promise for reducing tobacco-related disparities at the POS. Given the disparities-reducing potential of policies banning tobacco product sales near schools, jurisdictions with tobacco retailer licensing should consider adding this provision to their licensing requirements. Since relatively few jurisdictions currently ban tobacco sales near schools, future research should examine ways to increase and monitor the uptake of this policy, and assess

    The radioactivity in tobacco leaves collected from 15 different regions of Greece before cigarette production was studied in order to estimate the effective dose from cigarette tobacco due to the naturally occurring primordial radionuclides, such as 226 Ra and 210 Pb of the uranium series and 228 Ra of the thorium series and or man-made produced radionuclides, such as 137 Cs of Chernobyl origin. Gamma-ray spectrometry was applied using Ge planar and coaxial type detectors of high resolution and high efficiency. It was concluded that the annual effective dose due to inhalation for adults (smokers) for 226 Ra varied from 42.5 to 178.6 μSv y -1 (average 79.7 μSv y -1 ), while for 228 Ra from 19.3 to 116.0 μSv y -1 (average 67.1 μSv y -1 ) and for 210 Pb from 47.0 to 134.9 μSv y -1 (average 104.7 μSv y -1 ), that is the same order of magnitude for each radionuclide. The sum of the effective dose of the three natural radionuclides varied from 151.9 to 401.3 μSv y -1 (average 251.5 μSv y -1 ). The annual effective dose from 137 Cs of Chernobyl origin was three orders of magnitude lower as it varied from 70.4 to 410.4 μSv y -1 (average 199.3 μSv y -1 ). (author)

  4. [Can tobacco companies be good corporate citizens?].

    2009-07-01

    Tobacco companies have jumped on the Corporate social responsibility (CSR) bandwagon as a tentative to be societally accepted as responsible actors and good corporate citizens. This is however not possible for two reasons. First, the product they sell is lethal and thus not compatible with the precondition of doing no harm to be a good corporate citizen. Second, the behavior of tobacco firms is not responsible, being illustrated by four examples: junk science versus sound science strategy, seducing young smokers, political lobbying and getting customers on new markets. To conclude, three implications for regulating the activities of the tobacco industry are given.

    This paper seeks to outline the challenges of tobacco consumption control in the transitional economy of Croatia. It focuses on issues of taxation, high unemployment, and smuggling while attempting to meet European Union (EU) accession requirements for tobacco control legislation that reduces smoking consumption. The issue of tobacco control is not a simple one and requires a multi-pronged approach. While Croatia has made good progress in adopting legislation, it needs to strengthen its efforts both in terms of enforcement and increased taxation of cigarettes.

    Philip Morris Companies, the world's largest and most profitable tobacco seller, has changed its corporate name to The Altria Group. The company has also embarked on a plan to improve its corporate image. Examination of internal company documents reveals that these changes have been planned for over a decade and that the company expects to reap specific and substantial rewards from them. Tobacco control advocates should be alert to the threat Philip Morris's plans pose to industry focused tobacco control campaigns. Company documents also suggest what the vulnerabilities of those plans are and how advocates might best exploit them.

    diffusivity. Similarly, regions of high reactant mass fraction allow more vigorous thermal decomposition and thus attract straining. The migration outlined above has three important consequences: (1) Migration must be taken into account when inferring the width of the deforming zone from field observations. Even when the zone of localized straining is only a few tens of microns wide, migration can lead to a final strain profile with a zone of roughly uniform strain on the order of a millimeter wide. (2) For thermal pressurization the width of the deforming zone largely controls the initial weakening of the fault. A pre-existing zone of low hydraulic diffusivity localizes straining more efficiently leading to faster weakening. Thus, dynamic weakening may be controlled by the gouge properties in the region most susceptible to strain rate localization. (3) Migration of the localized zone distributes frictional heating over a broader region, leading to a much lower temperature rise when compared with a stationary shear zone. Our results rarely show temperatures above the melting temperature, providing a plausible explanation for the fact that melt signatures are rarely observed on mature faults active at shallower crustal depths.

    2008-09-01

    Between 1999 and 2001, British American Tobacco, Philip Morris, and Japan Tobacco International executed Project Cerberus to develop a global voluntary regulatory regime as an alternative to the Framework Convention on Tobacco Control (FCTC). They aimed to develop a global voluntary regulatory code to be overseen by an independent audit body and to focus attention on youth smoking prevention. The International Tobacco Products Marketing Standards announced in September 2001, however, did not have the independent audit body. Although the companies did not stop the FCTC, they continue to promote the International Tobacco Products Marketing Standards youth smoking prevention as an alternative to the FCTC. Public health civil society groups should help policymakers and governments understand the importance of not working with the tobacco industry.

    The chameleon mechanism enables a long range fifth force to be screened in dense environments when non-trivial self interactions of the field cause its mass to increase with the local density. To date, chameleon fifth forces have mainly been studied for spherically symmetric sources, however the non-linear self interactions mean that the chameleon responds to changes in the shape of the source differently to gravity. In this work we focus on ellipsoidal departures from spherical symmetry and ...

    2004-03-01

    This study examined storefront tobacco advertisements in 11 towns in Illinois from 1999 through 2001 to assess possible changes in these types of advertisements since the master tobacco settlement, which banned tobacco advertisements on billboards. Observers assessed the number of merchant- and industry-made tobacco storefront advertisements in Illinois stores and whether these advertisements were either brand- or price-focused. The relationship between the amount of tobacco advertisements and underage tobacco sales to minors was also explored. Findings indicated no significant relationships between tobacco advertisements and underage tobacco sales. However, industry price advertisements decreased over time because of tobacco price increases resulting from the master settlement, whereas industry brand advertisements increased over time, perhaps in an effort by the tobacco industry to retain sales of their products through brand recognition.

    Understanding of role of slow earthquakes as they relate to the occurrence of both megathrust earthquakes and tsunami earthquakes is necessary to mitigate these disasters in the near future. Laboratory shearing experiments is one of important approach to evaluate these relationships. Here, we use powdered gouge samples from JFAST (IODP Expedition 343) Hole C0019E, core sample 17R-1, which is the plate boundary fault zone in the Japan Trench subduction zone. In this region, both large coseismic slip during the 2011 Tohoku-Oki earthquake as well as discrete slow slip events (SSE) have occurred. Experiments were conducted in a single-direct shear apparatus under normal stress of 16 MPa, with total shear displacements of up to 16 mm. We evaluate both the velocity- and slip-dependence of friction by extracting the velocity-dependent friction parameters a, b, and Dc, and measuring the rate of change in friction coefficient with shear displacement as the slip-dependence of friction. We report that in friction experiments using the Tohoku fault zone samples, an increase in sliding velocity exceeding that of earthquake afterslip can induce a change from steady-state frictional strength or slip hardening friction to slip-weakening frictional behavior. Our results show that the slip weakening is observed when the slip velocity exceeds 1 x 10-6 m/s during our experiments, while steady-state frictional strength or slip hardening is observed below 1x10-6 m/s. In the Japan Trench region, two slow events were observed at the downdip edge of the mainshock coseismic slip zone (< 30 m) were observed. These are an episodic SSE with a slip velocity of 0.1 x 10-6, and afterslip after the largest foreshock with a slip velocity of 2 x 10-6 m/s. This suggests that the afterslip may have facilitated the large coseismic slip during the mainshock on the plate boundary fault of the Tohoku-Oki earthquake.

  13. Simultaneous reductions in emissions of black carbon and co-emitted species will weaken the aerosol net cooling effect

    Black carbon (BC), a distinct type of carbonaceous material formed from the incomplete combustion of fossil and biomass based fuels under certain conditions, can interact with solar radiation and clouds through its strong light-absorption ability, thereby warming the Earth's climate system. Some studies have even suggested that global warming could be slowed down in the short term by eliminating BC emission due to its short lifetime. In this study, we estimate the influence of removing some sources of BC and other co-emitted species on the aerosol radiative effect by using an aerosol-climate atmosphere-only model BCC_AGCM2.0.1_CUACE/Aero with prescribed sea surface temperature and sea ice cover, in combination with the aerosol emissions from the Representative Concentration Pathways (RCPs) scenarios. We find that the global annual mean aerosol net cooling effect at the top of the atmosphere (TOA) will be enhanced by 0.12 W m-2 compared with recent past year 2000 levels if the emissions of only BC are reduced to the level projected for 2100 based on the RCP2.6 scenario. This will be beneficial~for the mitigation of global warming. However, both aerosol negative direct and indirect radiative effects are weakened when BC and its co-emitted species (sulfur dioxide and organic carbon) are simultaneously reduced. Relative to year 2000 levels, the global annual mean aerosol net cooling effect at the TOA will be weakened by 1.7-2.0 W m-2 if the emissions of all these aerosols are decreased to the levels projected for 2100 in different ways based on the RCP2.6, RCP4.5, and RCP8.5 scenarios. Because there are no effective ways to remove the BC exclusively without influencing the other co-emitted components, our results therefore indicate that a reduction in BC emission can lead to an unexpected warming on the Earth's climate system in the future.

    Circles of Tobacco Wisdom (CTW) was an elder-led, community-based project that aimed to enhance tobacco control in the American Indian community. Its goal was to provide elders with the knowledge, opportunities, and support to enable them to assume leadership of a tobacco control movement that was grounded in the ceremonial traditions of tobacco use. The purpose of this study was to test the effects of the pilot intervention on participants. The design of this pilot study intervention was a single group, pre-post comparison, with a pre-post survey, monthly check-ins, and a post-1-year focus group. Twelve elders were included in the pre- and post-analyses. All twelve elders were women who self-identified as American Indian (mean age = 64). The CTW elders participated in monthly talking circles, quarterly learning sessions, and a post-1-year focus group, and took part in other learning, support, and community action opportunities. Data were collected from December 2008 through November 2009 and analyzed throughout the process. American Indian Elders' tobacco-related knowledge, perceptions, beliefs, and behaviors were measured while participating in the CTW project. Knowledge, perceptions, beliefs, and behavior changes were seen with cigarette smoking, secondhand smoke, and ceremonial tobacco use and risk perception. After 6 months, the number of people the elders had talked with about tobacco increased, elders were more likely to have a discussion on tobacco at a community event, and their comfort level talking about commercial and traditional tobacco also increased. A number of themes also were identified in the focus group: feeling more comfortable talking about tobacco issues, learning a lot about traditional and commercial tobacco, and realizing the dangers of smoking. Elders increased their knowledge about commercial and traditional tobacco and changed related attitudes as a result of CTW. Further, American Indian Elders perceived that CTW was effective

    To identify the historical nexus between Malaysia's largest and politically dominant ethnic group and the political economy of tobacco, and to consider the implications of this connection for tobacco control. Primary and secondary documentary sources in both English and Malay were analysed to illuminate key events and decisions, and the discourse of industry and government. Sources included: speeches by Malaysian political and industry actors; tobacco industry reports, press releases and websites; government documents; World Health Organization (WHO) tobacco control literature; and press reports. Malays have the highest smoking prevalence among Malaysia's major ethnic groups. The tobacco industry has consistently been promoted as furthering Malay economic development. Malays play the major role in growing and curing. Government-owned Malay development trusts have been prominent investors in tobacco corporations, which have cultivated linkages with the Malay elite. The religious element of Malay ethnicity has also been significant. All Malays are Muslim, and the National Fatwa Council has declared smoking to be haram (forbidden); however, the Government has declined to implement this ruling. Exaggerated claims for the socio-economic benefits of tobacco production, government investment and close links between tobacco corporations and sections of the Malay elite have created a conflict of interest in public policy, limited the focus on tobacco as a health policy issue among Malays and retarded tobacco control policy. More recently, ratification of the WHO Framework Convention on Tobacco Control, regional free trade policies reducing the numbers of growers, concerns about smoking from an Islamic viewpoint, and anxieties about the effects of smoking upon youth have increasingly challenged the dominant discourse that tobacco furthers Malay interests. Nevertheless, the industry remains a formidable political and economic presence in Malaysia that is likely to continue to

    Tobacco industry denormalization (TID) informs the public about the tobacco industry's role in the tobacco epidemic and is an important component of a comprehensive tobacco control strategy. Although TID beliefs have been noted in adult smokers and associated with intent to quit, research has not evaluated whether they are affected by smokers' level of nicotine dependence. The present article sought to concurrently examine how attitudes towards the tobacco industry and tobacco control groups may differ among smokers of varying levels of nicotine dependence. In addition, it evaluated how these attitudes and beliefs may be associated with smokers' intentions to reduce or quit smoking. A random digit dialing telephone survey was conducted of 889 Canadian current daily smokers, 18 years and older. Attitudes towards the tobacco industry were mixed among the entire cohort and differences in beliefs towards the tobacco industry were not found among smokers of varying levels of nicotine dependence. However, smokers that held strong TID beliefs were 5 times more intent to quit smoking than those without such beliefs. Compared to smokers with low level of nicotine dependence, heavy smokers were more likely to report strong overall displeasure with the tobacco control community (OR=1.98, 95% CI=1.23-3.19, p=0.005), however there were no differences with regards to future intent to quit. The absence of strong negative sentiment toward the tobacco industry among smokers as a whole suggests that more targeted anti-industry messages are needed, raising greater awareness of tobacco industry practices within smokers and non-smokers alike. As heavier smokers' discontent with the tobacco control community highlights increasing social disapproval and pressure to quit smoking, future educational and media strategies used for smoking cessation purposes may benefit from emphasizing more of the positive attributes associated with quitting smoking, as opposed to the negative features of

  17. Quasi-experimental evidence on tobacco tax regressivity.

    Koch, Steven F

    2018-01-01

    Tobacco taxes are known to reduce tobacco consumption and to be regressive, such that tobacco control policy may have the perverse effect of further harming the poor. However, if tobacco consumption falls faster amongst the poor than the rich, tobacco control policy can actually be progressive. We take advantage of persistent and committed tobacco control activities in South Africa to examine the household tobacco expenditure burden. For the analysis, we make use of two South African Income and Expenditure Surveys (2005/06 and 2010/11) that span a series of such tax increases and have been matched across the years, yielding 7806 matched pairs of tobacco consuming households and 4909 matched pairs of cigarette consuming households. By matching households across the surveys, we are able to examine both the regressivity of the household tobacco burden, and any change in that regressivity, and since tobacco taxes have been a consistent component of tobacco prices, our results also relate to the regressivity of tobacco taxes. Like previous research into cigarette and tobacco expenditures, we find that the tobacco burden is regressive; thus, so are tobacco taxes. However, we find that over the five-year period considered, the tobacco burden has decreased, and, most importantly, falls less heavily on the poor. Thus, the tobacco burden and the tobacco tax is less regressive in 2010/11 than in 2005/06. Thus, increased tobacco taxes can, in at least some circumstances, reduce the financial burden that tobacco places on households. Copyright © 2017 Elsevier Ltd. All rights reserved.

  18. Can Tobacco Control Be Transformative? Reducing Gender Inequity and Tobacco Use among Vulnerable Populations

    Science.gov (United States)

    Greaves, Lorraine

    2014-01-01

    Tobacco use and exposure is unequally distributed across populations and countries and among women and men. These trends and patterns reflect and cause gender and economic inequities along with negative health impacts. Despite a commitment to gender analysis in the preamble to Framework Convention on Tobacco Control there is much yet to be done to fully understand how gender operates in tobacco control. Policies, program and research in tobacco control need to not only integrate gender, but rather operationalize gender with the goal of transforming gender and social inequities in the course of tobacco control initiatives. Gender transformative tobacco control goes beyond gender sensitive efforts and challenges policy and program developers to apply gender theory in designing their initiatives, with the goal of changing negative gender and social norms and improving social, economic, health and social indicators along with tobacco reduction. This paper outlines what is needed to progress tobacco control in enhancing the status of gendered and vulnerable groups, with a view to reducing gender and social inequities due to tobacco use and exposure.

    2014-01-01

    The Family Smoking Prevention and Tobacco Control Act gives the Food and Drug Administration power to regulate tobacco products. This commentary calls for immediate regulation of the carcinogenic tobacco-specific nitrosamines 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and N’-nitrosonornicotine (NNN) in cigarette tobacco as a logical path to cancer prevention. NNK and NNN, powerful carcinogens in laboratory animals, have been evaluated as “carcinogenic to humans” by the International Agency for Research on Cancer. NNK and NNN are present in the tobacco of virtually all marketed cigarettes; levels in cigarette smoke are directly proportional to the amounts in tobacco. The NNK metabolite NNAL, itself a strong carcinogen, is present in the urine of smokers and non-smokers exposed to secondhand smoke. Some of the highest levels of NNK and NNN are found in U.S. products. It is well established that factors such as choice of tobacco blend, agricultural conditions, and processing methods influence levels of NNK and NNN in cigarette tobacco and cigarette smoke. Therefore, it is time to control these factors and produce cigarettes with 100 ppb or less each of NNK and NNN in tobacco, which would result in an approximate 15-20 fold reduction of these carcinogens in the mainstream smoke of popular cigarettes sold in the United States.

    Publicity is legally regulated in Spain, in order to avoid its misuse. Tobacco publicity is also under those regulation, having had the companies operating in this sector to adapt themselves through new strategies. In this work, the legal restrictions existing in Spain regarding publicity are analyzed, together with some of the strategies developed by tobacco companies in order to elude them. In this sense, and despite of the existing legal framework, it should be noticed that tobacco companies are cleverly taking advantage of the existence of legal loopholes in tobacco publicity to promote their products.

  2. Using tobacco-industry marketing research to design more effective tobacco-control campaigns.

    Ling, Pamela M; Glantz, Stanton A

    2002-06-12

    To improve tobacco-control efforts by applying tobacco-industry marketing research and strategies to clinical and public health smoking interventions, we analyzed previously secret tobacco-industry marketing documents. In contrast to public health, the tobacco industry divides markets and defines targets according to consumer attitudes, aspirations, activities, and lifestyles. Tobacco marketing targets smokers of all ages; young adults are particularly important. During the 1980s, cost affected increasing numbers of young and older smokers. During the 1990s, eroding social acceptability of smoking emerged as a major threat, largely from increasing awareness of the dangers of secondhand smoke among nonsmokers and smokers. Physicians and public health professionals should use tobacco-industry psychographic approaches to design more relevant tobacco-control interventions. Efforts to counter tobacco marketing campaigns should include people of all ages, particularly young adults, rather than concentrating on teens and young children. Many young smokers are cost sensitive. Tobacco-control messages emphasizing the dangers of secondhand smoke to smokers and nonsmokers undermine the social acceptability of smoking.

    Full Text Available By the late 1970s, eight technologies in the design of a ‘less hazardous’ cigarette were classified as significant. The eight included: The tobacco blend, the filter tip, filter-tip additives, reconstituted tobacco sheet, paper additives, air dilution via paper porosity, expanded tobacco, and air dilution via filter-tip perforation. In addition to these eight cigarette-design technologies was another proposed technology which involved the incorporation of a substitute for some or all of the tobacco in the cigarette filler. Despite considerable research and development (R&D effort on various tobacco substitutes that indicated the replacements in most instances fulfilled the definition of a ‘less hazardous’ cigarette with regard to the chemical and biological properties of their mainstream smoke, tobacco substitute-containing cigarettes failed to attain consumer acceptability. As a result, several marketed products containing tobacco substitutes had an extremely brief tenure in the marketplace. Outlined herein is a summary of some detailed research conducted on the composition of the mainstream smokes from cigarettes containing either all-substitute filler or fillers comprising various substitute and tobacco mixtures as well as an all-tobacco cigarette.

    2011-03-01

    The tobacco industry has challenged new FDA rules restricting outdoor tobacco advertising near schools and playgrounds on First Amendment grounds, arguing that they would lead to a near complete ban on tobacco advertising in dense urban areas. To examine how the 2009 Family Smoking Prevention and Tobacco Control Act (FSPTCA) rules banning outdoor tobacco advertising near schools and playgrounds would affect tobacco retailers. GIS spatial analyses of two different states (Missouri, New York), along with more detailed analyses of two urban areas within those states (St. Louis, New York City), were conducted in 2010. The percentage of tobacco retailers falling within 350-, 500-, and 1000-foot buffer zones was then calculated. 22% of retailers in Missouri and 51% in New York fall within 1000-foot buffers around schools. In urban settings, more retailers are affected, 29% in St. Louis and 79% in New York City. Sensitivity analyses demonstrate that smaller buffers decrease the proportion of affected retailers. That is, 350-foot buffers affect only 6.7% of retailers in St. Louis and 29% in New York City. The effects of new outdoor tobacco advertising restrictions vary by location and population density. In Missouri and New York, outdoor tobacco advertising would still be permitted in many locations if such advertising was prohibited in a 1000-foot buffer zone around schools and playgrounds. Much smaller buffer zones of 350 feet may result in almost no reduction of outdoor advertising in many parts of the country. Copyright © 2011. Published by Elsevier Inc.

    In the 1990s several American states passed term limits on legislators with the stated intention of reducing the influence of wealthy industries on career legislators. Although term limits in the United States do not have a direct relationship to public health, the tobacco industry anticipated that term limits could have indirect effects by either limiting or expanding industry influence. We detail the strategy of the tobacco industry in the wake of term limits using internal tobacco company documents and a database of campaign contributions made to legislators in term limited states between 1988 and 2002. Despite some expectations that term limits would limit tobacco industry access to state legislators, term limits appear to have had the opposite effect. Copyright © 2013 Elsevier Ltd.

    Harm perceptions about tobacco products may influence initiation, continued use, and cessation efforts. We assessed associations between adult traditional tobacco product use and absolute harm perceptions of traditional and alternative tobacco products. We also described the topics individuals looked for during their last search for information, their beliefs about chemicals in cigarettes/cigarette smoke, and how both relate to harm perceptions. We ran multivariable models with jackknife replicate weights to analyze data from the 2015 administration of the National Cancer Institute's Health Information National Trends Survey (N=3376). Compared to never users, individuals reported lower perceived levels of harm for products they use. Among current tobacco users, ethnicity, thinking about chemicals in tobacco, and information-seeking were all factors associated with tobacco product harm perceptions. In the full sample, some respondents reported searching for information about health effects and cessation and held misperceptions about the source of chemicals in tobacco. This study fills a gap in the literature by assessing the absolute harm perceptions of a variety of traditional and alternative tobacco products. Harm perceptions vary among tobacco products, and the relationship among tobacco use, information seeking, thoughts about chemicals in tobacco products, and harm perceptions is complex. Data suggest that some individuals search for information about health effects and cessation and hold misperceptions about chemicals in tobacco products. Future inquiry could seek to understand the mechanisms that contribute to forming harm perceptions and beliefs about chemicals in tobacco products. Published by Elsevier Ltd.

    The progestogen 17-α hydroxyprogesterone caproate (17-OHPC) is 1 of only 2 agents recommended for clinical use in the prevention of spontaneous preterm delivery, and studies of its efficacy have been conflicting. We have developed an in-vitro model to study the fetal membrane weakening process that leads to rupture in preterm premature rupture of the fetal membranes (pPROM). Inflammation/infection associated with tumor necrosis factor-α (TNF-α) induction and decidual bleeding/abruption associated thrombin release are leading causes of preterm premature rupture of the fetal membranes. Both agents (TNF-α and thrombin) cause fetal membrane weakening in the model system. Furthermore, granulocyte-macrophage colony-stimulating factor (GM-CSF) is a critical intermediate for both TNF-α and thrombin-induced fetal membrane weakening. In a previous report, we demonstrated that 3 progestogens, progesterone, 17-alpha hydroxyprogesterone (17-OHP), and medroxyprogesterone acetate (MPA), each inhibit both TNF-α- and thrombin-induced fetal membrane weakening at 2 distinct points of the fetal membrane weakening pathway. Each block both the production of and the downstream action of the critical intermediate granulocyte-macrophage colony-stimulating factor. The objective of the study was to characterize the inhibitory effects of 17-OHPC on TNF-α- and thrombin-induced fetal membrane weakening in vitro. Full-thickness human fetal membrane fragments from uncomplicated term repeat cesarean deliveries were mounted in 2.5 cm Transwell inserts and cultured with/without 17-alpha hydroxyprogesterone caproate (10 -9 to 10 -7 M). After 24 hours, medium (supernatant) was removed and replaced with/without the addition of tumor necrosis factor-alpha (20 ng/mL) or thrombin (10 U/mL) or granulocyte-macrophage colony-stimulating factor (200 ng/mL). After 48 hours of culture, medium from the maternal side compartment of the model was assayed for granulocyte-macrophage colony

    Tobacco control efforts in Japan have lagged other high income countries, possibly because the Japanese government partially owns Japan Tobacco, Inc. In Japan, tobacco use is still often regarded as an issue of manners rather than an issue of health. Information about tobacco is available, but may not always be accurate. We explored what information Japanese consumers might access by reading popular Japanese books about tobacco. We searched Amazon.com Japan using the term "Tobacco", identifying the top 12 books by "relevance" and "bestselling." We eliminated duplicates and books not concerned with tobacco use and classified the remaining books as pro-smoking, anti-smoking, or neutral. We reviewed the pro-smoking books, published 2004-2009, and analyzed examples of misinformation by theme. Pro-smoking popular books conveyed five types of misinformation: doubt about science; suggestions that smoking increased health, longevity, virility, etc.; trivializing tobacco's effects; attacking public health advocates/authorities; and linking tobacco use with authenticity, history, or civil rights. At least one book was authored by a former Japan Tobacco employee; another used a popular Japan Tobacco advertising phrase. Creating doubt and confusion about tobacco serves tobacco industry interests and re-creates a strategy developed by US tobacco interests more than 40 years ago. Japanese readers may be misled by texts such as those reviewed. Tobacco control and public health advocates in Japan and globally should expose and counter such misinformation. "Naming and shaming" may be effective.

    Full Text Available During field weakening operation time (FWOT, the total iron loss rises and affects the accuracy of loss prediction and efficiency, especially if a large range of FWOT exists due to a large voltage drop that was rooted from the resistance of the used material. Iron loss prediction is widely employed in investigations for a fast electrical machine analysis using 2D finite element analysis (FEA. This paper proposes harmonic loss analytically by a steady-state equivalent circuit with a novel procedure. Consideration of skin effects and iron saturation are utilized in order to examine the accuracy through the relative error distribution in the frequency domain of each model from 50 to 700 Hz. Additionally, this comparative study presents a torque-frequency-field density calculation over each single term of the modified institute of electrical machines formula (IEM-Formula. The proposed analytical calculation is performed using 2D FEA for a classic and modified IEM-Formula along with experimental verifications on a surface-mounted permanent magnet synchronous generator (PMSG for a wind generation application.

    With the emergence of the anti-ship missle with the capability of infrared imaging guidance, the traditional single jamming measures, because of the jamming mechanism and technical flaws or unsuitable use, greatly reduced the survival probability of the war-ship in the future naval battle. Intergrated jamming of IR weakening + smoke-screen Can not only make jamming to the search and tracking of IR imaging guidance system , but also has feasibility in conjunction, besides , which also make the best jamming effect. The research conclusion has important realistic meaning for raising the antimissile ability of surface ships. With the development of guidance technology, infrared guidance system has expanded by ir point-source homing guidance to infrared imaging guidance, Infrared imaging guidance has made breakthrough progress, Infrared imaging guidance system can use two-dimensional infrared image information of the target, achieve the precise tracking. Which has Higher guidance precision, better concealment, stronger anti-interference ability and could Target the key parts. The traditional single infrared smoke screen jamming or infrared decoy flare interference cannot be imposed effective interference. So, Research how to effectively fight against infrared imaging guided weapons threat measures and means, improving the surface ship antimissile ability is an urgent need to solve.

  10. Disrupting the memory of places induced by drugs of abuse weakens motivational withdrawal in a context-dependent manner.

    Addicts repeatedly relapse to drug seeking even after years of abstinence, and this behavior is frequently induced by the recall of memories of the rewarding effects of the drug. Established memories, including those induced by drugs of abuse, can become transiently fragile if reactivated, and during this labile phase, known as reconsolidation, can be persistently disrupted. Here we show that, in rats, a morphine-induced place preference (mCPP) memory is linked to context-dependent withdrawal as disrupting the reconsolidation of the memory leads to a significant reduction of withdrawal evoked in the same context. Moreover, the hippocampus plays a critical role in linking the place preference memory with the context-conditioned withdrawal, as disrupting hippocampal protein synthesis and cAMP-dependent-protein kinase A after the reactivation of mCPP significantly weakens the withdrawal. Hence, targeting memories induced by drugs may represent an important strategy for attenuating context-conditioned withdrawal and therefore subsequent relapse in opiate addicts.

    The Word Health Organization's Framework Convention on Tobacco Control calls on parties to implement evidenced-based tobacco control policies, which includes Article 8 (protect the public from exposure to tobacco smoke), and Article 13 (tobacco advertising, promotion and sponsorship (TAPS)). In 2015, Uganda passed the Tobacco Control Act 2015 which includes a comprehensive ban on smoking in all public places and on all forms of TAPS. Prior to implementation, we sought to assess practices related to protection of the public from tobacco smoke exposure, limiting access to tobacco products and TAPS in restaurants and bars in Kampala City to inform implementation of the new law. This was a cross-sectional study that used an observational checklist to guide observations. Assessments were: whether an establishment allows for tobacco products to be smoked on premises, offer of tobacco products for sale, observation of tobacco products for sale, tobacco advertising posters, illuminated tobacco advertisements, tobacco promotional items, presence of designated smoking zones, no-smoking signs and posters, and observation of indoor smoking. Managers of establishments were also asked whether they conducted tobacco product sales promotions within establishments. Data were collected in May 2016, immediately prior to implementation of the smoke-free and TAPS laws. Of the 218 establishments in the study, 17% ( n  = 37) had no-smoking signs, 50% ( n  = 108) allowed for tobacco products to be smoked on premises of which, 63% ( n  = 68) had designated smoking zones. Among the respondents in the study, 33.3% ( n  = 72) reported having tobacco products available for sale of which 73.6% ( n  = 53) had manufactured cigarettes as the available tobacco products. Eleven percent ( n  = 24) of respondents said they conducted tobacco promotion within their establishment while 7.9% ( n  = 17) had promotional items given to them by tobacco companies. Hospitality

    Tobacco advertising in Indonesia is among the most aggressive and innovative in the world, and tobacco advertisements saturate the environment. Tobacco companies are politically and financially powerful in the country because they are one of the largest sources of government revenue. As a result, there are few restrictions on tobacco marketing and advertising. National surveys reveal that 62% of men and 1% to 3% of women are smokers. Over 90% of smokers smoke clove cigarettes (kretek). This paper examines the social and cultural reasons for smoking in Indonesia and discusses how the tobacco industry reads, reproduces and works with culture as a means of selling cigarettes. An analysis is provided of how kretek tobacco companies represent themselves as supporters of Indonesian national identity. This analysis is used to identify strategies to break the chains of positive association that currently support widespread smoking. Between November 2001 and March 2007, tobacco advertisements were collected from a variety of sources, including newspapers and magazines. Frequent photographic documentation was made of adverts on billboards and in magazines. Advertisements were segmented into thematic units to facilitate analysis. In all, 30 interviews were conducted with smokers to explore benefits and risks of smoking, perceptions of advertisements and brand preferences. Focus groups (n = 12) were conducted to explore and pretest counter advertisements. Key themes were identified in tobacco advertisements including control of emotions, smoking to enhance masculinity and smoking as a means to uphold traditional values while simultaneously emphasising modernity and globalisation. Some kretek advertisements are comprised of indirect commentaries inviting the viewer to reflect on the political situation and one's position in society. After identifying key cultural themes in cigarette advertisements, our research group is attempting to engage the tobacco industry on "cultural

    Few frameworks have addressed work-force diversity, inequities and inequalities as part of a comprehensive approach to eliminating tobacco-related health disparities. This paper summarizes the literature and describes the known disparities that exist along the tobacco disease continuum for minority racial and ethnic groups, those living in poverty, those with low education and blue-collar and service workers. The paper also discusses how work-force diversity, inequities in research practice and knowledge allocation and inequalities in access to and quality of health care are fundamental to addressing disparities in health. We examined the available scientific literature and existing public health reports to identify disparities across the tobacco disease continuum by minority racial/ethnic group, poverty status, education level and occupation. Results indicate that differences in risk indicators along the tobacco disease continuum do not explain fully tobacco-related cancer consequences among some minority racial/ethnic groups, particularly among the aggregate groups, blacks/African Americans and American Indians/Alaska Natives. The lack of within-race/ethnic group data and its interactions with socio-economic factors across the life-span contribute to the inconsistency we observe in the disease causal paradigm. More comprehensive models are needed to understand the relationships among disparities, social context, diversity, inequalities and inequities. A systematic approach will also help researchers, practitioners, advocates and policy makers determine critical points for interventions, the types of studies and programs needed and integrative approaches needed to eliminate tobacco-related disparities.

  17. Poverty, tobacco, and health: an Indian scenario.

    Majra, J P; Gur, A

    2009-06-01

    Poverty and health have a two-way relationship. Poverty increases the vulnerability of people to disease, and sickness affects their income leading to poverty. Tobacco has been identified as a major avoidable cause of illness and premature death. In India, more than half of men and one-tenth of women use one or more forms of tobacco. Tobacco-use shows a clear and continual increase with decreasing wealth quintiles. Poor smokers, who are at a greater risk of illness, are also at a greater risk of not being treated or of falling into greater poverty if they seek treatment. Poor people spend money on tobacco that could be spent on food, shelter, education, and healthcare. These decisions can entrench families in an ongoing cycle of poverty and ill-health. The direct and indirect costs of tobacco-use are immense for national economy. This has positioned control of tobacco relevant in India's per suite to achieve the goals of poverty eradication and health for all.

  18. Development of an integrated tobacco endgame strategy.

    van der Eijk, Yvette

    2015-07-01

    In recent years, various tobacco 'endgame' strategies have been suggested as a means to phase out tobacco consumption. Using country examples, this paper discusses three potential strategies: replacing cigarettes with alternative products (harm reduction), denying tobacco sales to people born after a certain year (the tobacco-free generation proposal), and further implementing measures based on the WHO Framework Convention for Tobacco Control (FCTC) treaty. It is argued that all strategies have potential issues that could be avoided by combining them into an integrated, sequential endgame that, first, using measures recommended in the WHO FCTC, creates a climate that facilitates the phasing out of cigarettes; second, implements a generational phase out of cigarette sales; and third, simultaneously permits the regulated use of alternative nicotine products. Thus, integrating ideas from various endgame strategies will result in a more effective, resilient tobacco endgame policy. Published by the BMJ Publishing Group Limited.

  19. Assessment of the carcinogenic N-nitrosodiethanolamine in tobacco products and tobacco smoke

    International Nuclear Information System (INIS)

    Brunnemann, K.D.; Hoffmann, D.

    1981-01-01

    A simple, reproducible gas chromatography-thermal energy analyzer (g.c.-TEA) method has been developed for the analysis of N-nitrosodiethanolamine (NDELA) in tobacco and tobacco smoke. The extract of tobacco or the trapped particulates of tobacco smoke are chromatographed on silica gel. The NDELA containing fractions are concentrated, silylated and analyzed with a modified g.c.-TEA system. [/sup 14/C]NDELA serves as internal standard for the quantitative analysis. Experimental cigarettes made from tobaccos which were treated with the sucker growth inhibitor maleic hydrazidediethanolamine (MH-DELA) contained 115--420 p.p.b. of NDELA and their smoke contained 20--290 ng/cigarette, whereas hand-suckered tobacco and its smoke were free of NDELA. The tobacco of US smoking products contained 115--420 p.p.b. of NDELA and the mainstream smoke from such products yielded 10--68 ng/cigar or cigarette. NDELA levels in chewing tobacco ranged from 220--280 p.p.b. and in two commercial snuff products were 3,200 and 6,800 p.p.b. Although the five analyzed MH-DELA preparations contained between 0.6--1.9 p.p.m. NDELA it is evident that the major portion of NDELA in tobacco is formed from the DELA residue during the tobacco processing. Based on bioassay data from various laboratories which have shown that NDELA is a relatively strong carcinogen and based on the results of this study the use of MH-DELA for the cultivation of tobacco is questioned

    Increases in tobacco taxation are acknowledged to be one of the most effective tobacco control interventions. This study aimed at determining the mediating role of socioeconomical status (SES) and the earmarking of revenue to healthcare and tobacco control, in influencing population support for the adoption of a 2 Euro tobacco tax increase in Greece, amid the challenging economic environment and current austerity measures. Data was collected from two national household surveys, the "Hellas Health III" survey, conducted in October 2010 and the "Hellas Tobacco survey" conducted in September 2012. Data was analyzed from 694 and 1066 respondents aged 18 years or more, respectively. Logistic regression models were fitted to measure the adjusted relationship between socio-economic factors for the former, and support for increased taxation on tobacco products for the latter. In 2012 amidst the Greek financial crisis, population support for a flat two euro tax increase reached 72.1%, if earmarked for health care and tobacco control, a percentage high both among non-smokers (76%) and smokers (64%) alike. On the contrary, when not earmarked, only 43.6% of the population was in support of the equivalent increase. Women were more likely to change their mind and support a flat two-euro increase if the revenue was earmarked for health care and tobacco control (aOR = 1.70; 95% C.I: 1.22-2.38, p = 0.002). Furthermore, support for an increase in tobacco taxation was not associated with SES and income. Despite dire austerity measures in Greece, support for an increase in tobacco taxation was high among both smokers and non-smokers, however, only when specifically earmarked towards health care and tobacco control. This should be taken into account not only in Greece, but within all countries facing social and economic reform.

    2014-06-20

    We aimed to explore New Zealand tobacco retailers' views on selling tobacco, the forthcoming 2012 point of sale display ban and two other potential tobacco control interventions in the retail setting: compulsory sales of nicotine replacement therapy and licensing of tobacco retailers. We carried out in-depth interviews with 18 retailers from a variety of store types where tobacco was sold. Stores were selected from a range of locations with varying levels of deprivation. We used thematic analysis to analyse the data. All but four of the retailers were ambivalent about selling tobacco, would rather not sell it, or fell back on a business imperative for justification. Only one retailer was explicitly unconcerned about selling tobacco products. Most participants had few or no concerns about the removal of point-of-sale displays. Issues which were raised were mainly practical and logistical issues with the removal of displays. Only three thought sales would definitely be reduced. The majority of the retailers were not opposed to a possible requirement that nicotine replacement therapy products be made available wherever tobacco products are sold. Ten supported a licensing or registration scheme for tobacco retailers, and only three were opposed. We found widespread ambivalence about selling tobacco. There was considerable support for the licensing of tobacco retailers and other potential tobacco control measures. The retailers' attitudes about potential financial costs and security issues from a tobacco display ban were at odds with the tobacco industry predictions and the views of retailers' organisations. Some retailers appear to be potential allies for tobacco control. This is in contrast to retailer organisations, which may be out of step with many of their members in their strong opposition to retail tobacco control interventions.

    Hospitality establishments in Kampala are not protecting the public from tobacco smoke exposure nor adequately limiting access to tobacco products. Effective dissemination of the Tobacco Control Act 2015 is important in ensuring that owners of public places are aware of their responsibility of complying with critical tobacco control laws. This would also likely increase self-enforcement among owners of hospitality establishments and public patrons of the no-smoking restrictions.

  3. Preventing tobacco-caused cancer: a call to action.

    Orleans, C T

    1995-11-01

    Nicotine addiction is the most common serious medical problem in the country. Tobacco use is responsible for 30% of cancer deaths in the United States and 90% of all lung cancer deaths. The physical addiction to nicotine explains why over 30% of Americans continue to smoke or use tobacco despite their desires and efforts to quit. The testimony summarized in this paper recommends four broad strategies for preventing tobacco-caused cancers in the United States: a) mandating and reimbursing effective treatments for nicotine addiction; b) increasing Federal and state tobacco excise taxes and earmarking a fraction of tax revenues for tobacco prevention and cessation; c) enacting other policy changes to prevent tobacco use and addiction among children, including expanded clean indoor air legislation, comprehensive youth tobacco access legislation, and the regulation of tobacco products and their advertising and promotion; and d) expanding tobacco control research and critical Federal research support. Specific recommendations are given for each broad strategy.

    Rodeo is one of the few sports still sponsored by the tobacco industry, particularly the US Smokeless Tobacco Company. Rodeo is popular in rural communities, where smokeless tobacco use is more prevalent. We used previously secret tobacco industry documents to examine the history and internal motivations for tobacco company rodeo sponsorship. Rodeos allow tobacco companies to reach rural audiences and young people, enhance brand image, conduct market research, and generate positive press. Relationships with athletes and fans were used to fight proposed restrictions on tobacco sports sponsorship. Rodeo sponsorship was intended to enhance tobacco sales, not the sport. Rural communities should question the tradition of tobacco sponsorship of rodeo sports and reject these predatory marketing practices.

  6. The case for the plain packaging of tobacco products.

    Freeman, Becky; Chapman, Simon; Rimmer, Matthew

    2008-04-01

    The Framework Convention on Tobacco Control (FCTC) requires nations that have ratified the convention to ban all tobacco advertising and promotion. In the face of these restrictions, tobacco packaging has become the key promotional vehicle for the tobacco industry to interest smokers and potential smokers in tobacco products. This paper reviews available research into the probable impact of mandatory plain packaging and internal tobacco industry statements about the importance of packs as promotional vehicles. It critiques legal objections raised by the industry about plain packaging violating laws and international trade agreements. Searches for available evidence were conducted within the internal tobacco industry documents through the online document archives; tobacco industry trade publications; research literature through the Medline and Business Source Premier databases; and grey literature including government documents, research reports and non-governmental organization papers via the Google internet search engine. Plain packaging of all tobacco products would remove a key remaining means for the industry to promote its products to billions of the world's smokers and future smokers. Governments have required large surface areas of tobacco packs to be used exclusively for health warnings without legal impediment or need to compensate tobacco companies. Requiring plain packaging is consistent with the intention to ban all tobacco promotions. There is no impediment in the FCTC to interpreting tobacco advertising and promotion to include tobacco packs.

  7. Tobacco Research and Its Relevance to Science, Medicine and Industry

    Full Text Available This article is a historical review and a vision for the future of tobacco plant research. This is the perspective of an experienced tobacco scientist who devoted his total professional career to tobacco research. From the very beginning, pioneering tobacco research was the foundation of plant science at the dawn of modern development, in such areas as light, nutrition, genetics, growth control, disorders and metabolism. Tobacco research led to current advancements in plant biotechnology. In addition, tobacco plant research contributed significantly to public health research in radioactive elements, mycotoxins, and air pollutants. However, public support for tobacco research has today greatly declined to almost total elimination because of a sense of political correctness. This author points out that tobacco is one of the most valuable research tools, and is a most abundant source of scientific information. Research with tobacco plants will contribute far beyond the frontiers of agricultural science: tobacco can be a source of food supply with nutrition value similar to that of milk; tobacco can be a source of health supplies including medical chemicals and various vaccines; tobacco can be a source of biofuel. All we need is to treat tobacco with respect; the use of tobacco is only in its initial stages.

    An important approach to reduce youth tobacco use is the adoption of regulations to prohibit tobacco product sale to individuals younger than 21 years, termed Tobacco 21. In the United States, close to 90% of current smokers started smoking before the age of 18 years, and 99% before age 26 years. Earlier age of tobacco use initiation is associated with lower rates of smoking cessation. Increasing minimum age to purchase has been shown to reduce tobacco product use among youth. The critical determinant is likely the loss of social sources of tobacco products. Enforcement activities are important for age-of-purchase laws to be effective. Raising the minimum legal age to purchase tobacco products to 21 years is highly supported among both the smoking and nonsmoking public. Tobacco sales to those younger than 21 years account for just 2% of total tobacco sales, yet produce 90% of new smokers. The short-term effect on small business of raising the minimum age to purchase would be minimal. Small businesses will have time to adapt to the decrease in tobacco sales as fewer youth grow up nicotine addicted. Raising the minimum age to purchase of tobacco and nicotine products to 21 years, combined with enforcement of those restrictions, will help protect future generations from a lifetime of tobacco dependence and associated morbidity. These regulations should apply to all tobacco products, including electronic nicotine delivery systems. Respiratory health care providers should educate their local, state, and federal policy makers on the importance of Tobacco 21.

    Cross-sectional data suggests that adolescents' receptivity to the advertising of smokeless tobacco is correlated with use of chewing tobacco or snuff. Lack of longitudinal data has precluded determination of whether advertising receptivity precedes or follows initiation of smokeless tobacco. The objective of this study was to test for the association between advertising receptivity and subsequent initiation of smokeless tobacco among adolescent males. Adolescent males from the 1993-1999 Teen Longitudinal California Tobacco Survey were selected at the baseline survey for never having used smokeless tobacco. Separate longitudinal analyses corresponded to two dependent variables, ever use of smokeless tobacco (1993-1996; N = 1,388) and use on 20 or more occasions (1993-1999; N = 1,014). Models were adjusted for demographic variables, risk factors for smokeless tobacco use, and exposure to users of smokeless tobacco. Advertising receptivity at baseline was predictive of ever use by late adolescence (RR(95% CI) = 2.0 (1.5, 2.8)) and regular use by young adulthood (RR(95% CI) = 3.7 (2.1, 6.7)) in models that were adjusted for covariates. Conclusions/ Importance: The findings challenge the tobacco industry's assertion that tobacco marketing does not impact youth initiation. This is particularly relevant to tobacco control in the United States because the 2009 Tobacco Control Act places fewer restrictions on smokeless tobacco products compared to cigarettes.

    Full Text Available Background: Tobacco use is very common among Indian society. In fact, tobacco use is responsible for majority of morbidity and mortality in India and worldwide. Tobacco has been identified as “addictive” and tobacco dependence has been defined as a health problem in ICD-10. Aims & Objectives: This review article aims to emphasize the role of primary health care providers in tobacco cessation and to give recommendations after identifying barriers and exploring the present scenario. Material Methods: Several studies, journals and web-based articles have been referred to support the evidence that a brief tobacco cessation advice from physicians could help the patient quit. Result: Studies show that there is lack of participation from primary health care providers for tobacco cessation. Several barriers have been identified in many studies and also there exist some solutions to these barriers. Conclusion: It has been concluded in the article that primary health care providers should be trained and supported with all possible resources so that they can screen tobacco use in patients and could help them quit.

  12. [The plain packaging of tobacco products: a new strategy for tobacco control].

    There is evidence that global tobacco smoking control policies contribute to decrease the prevalence of smoking among populations, so there is a need to effectively implement different measures in a coordinated way. The plain packaging and labelling of tobacco products is one of the measures proposed by the World Health Organisation Framework Convention on Tobacco Control. At the moment, leading countries are implementing this tobacco control measure, which involves a plain packaging for all tobacco products, i.e., the absence of any promotional or communication tool in the packaging, except the name of the brand, appearing with a standardised font, size, colour and placing in the pack. Australia was the first country to implement this measure in 2012 and recently other countries are legislating and approving it. In Spain, tobacco legislation (2005 and 2010), was an important advance in tobacco control policies. The introduction of plain packaging in Spain would mean the next step in the development of a global strategy for fighting this significant health problem. The aim of this article is to synthesise in a structured manner the role that the packaging of tobacco products has within marketing and communication strategies, as well as to describe the potential effects that the plain packaging has on some aspects of smoking behaviour, according to current literature.

    To explore tobacco industry accounts of its use of indirect tobacco advertising and trademark diversification (TMD) in Malaysia, a nation with a reputation for having an abundance of such advertising. Systematic keyword and opportunistic website searches of formerly private tobacco industry internal documents made available through the Master Settlement Agreement. 132 documents relevant to the topic were reviewed. TMD efforts were created to advertise cigarettes after advertising restrictions on direct advertising were imposed in 1982. To build public credibility the tobacco companies set up small companies and projected them as entities independent of tobacco. Each brand selected an activity or event such as music, travel, fashion, and sports that best suited its image. RJ Reynolds sponsored music events to advertise its Salem brand while Philip Morris used Marlboro World of Sports since advertising restrictions prevented the use of the Marlboro man in broadcast media. Despite a ban on tobacco advertisements in the mass media, tobacco companies were the top advertisers in the country throughout the 1980s and 1990s. The media's dependence on advertising revenue and support from the ruling elite played a part in delaying efforts to ban indirect advertising. Advertising is crucial for the tobacco industry. When faced with an advertising ban they created ways to circumvent it, such as TMDs.

    Purpose Use of other tobacco products (smokeless tobacco, hookah, cigarillo, e-cigarettes) is increasing, particularly among young adults, and there are few regulations on marketing for these products. We examined the associations between tobacco marketing receptivity and other tobacco product (OTP) use among young adult bar patrons (aged 18-26 years). Methods Time-location sampling was used to collect cross-sectional surveys from 7,540 young adult bar patrons from January 2012 through March of 2014. Multivariable logistic regression analyses in 2015 examined if tobacco marketing receptivity was associated (1) with current (past 30 day) OTP use controlling for demographic factors, and (2) with dual/poly use among current cigarette smokers (n=3,045), controlling for demographics and nicotine dependence. Results Among the entire sample of young adult bar patrons (Mage=23.7, SD=1.8; 48.1% female), marketing receptivity was consistently associated with current use of all OTP including smokeless tobacco (adjusted odds ratio [AOR]= 2.49, 95% confidence interval [CI] 1.90-3.27, pmarketing receptivity was significantly associated with use of smokeless tobacco (AOR=1.44, 95% CI 1.05-1.98, pmarketing receptivity. Efforts to limit tobacco marketing should address OTP in addition to cigarettes. PMID:27707516

  16. The key role of ozone depleting substances in weakening the Walker Circulation over the second half of the 20th Century

    It is widely believed that the Walker Circulation will weaken in response to increasing greenhouse gases (GHG) by the end of the 21st century. But over the 20th century, the existence of a statistical significant weakening trends in the observations remains unclear. We here present new modelling evidence showing that Ozone Depleting Substances (ODS) may have significantly contributed to the weakening of the Walker Circulation over the years 1955-2005. While the primary impact of increasing ODS has been the formation of the ozone hole, it is perhaps not as widely appreciated that ODS are also powerful greenhouse gases. Using an ensemble of integrations with the the Whole Atmosphere Chemistry Climate Model, we show that the surface warming caused by increasing ODS over the second half of the 20th century causes a statistically significant weakening of the Walker Circulation in the model. In fact, we find that the increase of the other well-mixed GHG alone leads to a strengthening, not a weakening of the Walker Circulation, over that period in our model. When ODS concentrations are held fixed at 1950's levels, the effect of the other GHG is not sufficient, and a warming delay in the eastern tropical Pacific SST leads to an increase in the east-west SST gradient which is accompanied by a strengthening of the Walker Circulation. But, when the forcing from ODS is added in, the additional radiative forcing causes the eastern Pacific to warm faster, and the trend in the Walker Circulation reverses sign and becomes negative over the second half of the 20th century.

    We present the results of high-speed rotary shear experiments on gouge recovered from the Central Deforming Zone (CDZ) of the San Andreas Fault (SAF) during Phase 3 drilling of the San Andreas Fault Observatory at Depth (SAFOD). The SAFOD borehole transected and recovered samples from two actively creeping segments of the fault. Aseismic creep produced noticeable borehole deformation between 2005 and 2007 in the vicinity of the two m-thick gouge interval that defines the CDZ. The sample tested is a well-foliated smectite - rich gouge that contains clasts of serpentine, quartz, feldspar, and opaques. The sample was gently flaked to ~600 μm to preserve the clay fabric; a ~1 mm thick layer was sheared between gabbro blocks 25 mm in diameter and semi-sealed with a press-fit Teflon ring. Experiments were conducted at a constant normal stress of 0.3 to 1.5 MPa, velocity of 0.1 to 1.3 m/s, and displacement up to 20 m (velocity and displacement refer to the local condition at 2/3 the sample radius). We tested both room-dry and water-saturated gouge at room temperature. Temperatures were measured on a representative suite of samples using 5 thermocouples at various radial positions and distances from the gouge layer. Microstructural analyses were conducted on radial cut thin sections which show slip-perpendicular structures formed under spatial gradients in velocity and displacement. The CDZ gouge weakens with an increase in velocity. The steady-state coefficient of friction of the wet gouge varies from μ = 0.40 at 0.1 m/s to μ = 0.14 at 1.3 m/s. Temperature within the gouge layer exceeds the water-vapor phase transition temperature in the water-saturated gouge sheared at 0.35-1.3 m/s. In general, the coefficient of friction and temperature of the dry gouge is greater than that of the wet gouge. Microstructures show a progression in deformation mechanisms with increasing displacement and velocity. Lens-shaped zones of poorly-foliated starting material are preserved in

    To assess whether tobacco content found in video games was appropriately labelled for tobacco-related content by the Entertainment and Software Ratings Board (ESRB). Sixty-five gamer participants (self-identified age range 13-50) were interviewed in-person (n=25) or online (n=40) and asked (A) to list favourite games and (B) to name games that they could recall containing tobacco content. The ESRB database was searched for all games mentioned to ascertain whether they had been assigned tobacco-related content descriptors. Games were independently assessed for tobacco content by examining user-created game wiki sites and watching YouTube videos of gameplay. Games with tobacco-related ESRB content descriptors and/or with tobacco imagery verified by researchers were considered to contain tobacco content. Games identified by participants as including tobacco but lacking verifiable tobacco content were treated as not containing tobacco content. Participants recalled playing 140 unique games, of which 118 were listed in the ESRB database. Participants explicitly recalled tobacco content in 31% (37/118) of the games, of which 94% (35/37) included independently verified tobacco content. Only 8% (9/118) of the games had received ESRB tobacco-related content descriptors, but researchers verified that 42% (50/118) contained such content; 42% (49/118) of games were rated 'M' for mature (content deemed appropriate for ages 17+). Of these, 76% (37/49) contained verified tobacco content; however, only 4% (2/49) received ESRB tobacco-related content descriptors. Gamers are exposed to tobacco imagery in many video games. The ESRB is not a reliable source for determining whether video games contain tobacco imagery. Published by the BMJ Publishing Group Limited.

    Tobacco products in the United States and the patterns of tobacco use are changing. Although cigarette smoking prevalence has declined, dental professionals are likely to encounter substantial numbers of patients who have tried and are continuing to use new and alternative tobacco products, including cigars, water pipes (hookahs), and electronic cigarettes, as well as conventional and new smokeless tobacco products. The authors reviewed conventional and new tobacco products in the United States, their adverse oral and systemic health effects, and their prevalence of use. Tobacco products other than cigarettes account for a substantial portion of tobacco use. For this reason, tobacco-use prevention and cessation counseling provided by dental health care professionals must address all tobacco products, including cigarettes, cigars, water pipes, and electronic cigarettes, as well as conventional and new smokeless tobacco products. Cigarette smoking and smokeless tobacco use are associated with immediate and long-term adverse health effects, including nicotine addiction, oral and systemic disease, and death. Novel products may attract new tobacco users, potentially leading to addiction that results in enduring tobacco product use and associated adverse health effects. This critical review of conventional, new, and emerging tobacco products presents information that dental professionals can use in providing tobacco-related counseling to patients who use or who are at risk for using tobacco products. It is essential that dental professionals are knowledgeable about tobacco products and are able to answer patients' questions and provide them with evidence-based tobacco-related counseling. This information may prevent patients from initiating use or help reduce or cease use to avoid immediate and long-term adverse health effects, including nicotine addiction, oral and systemic disease, and death.

    Limited information exists about strategies and methods used on brand marketing websites to transmit pro-tobacco messages to tobacco users and potential users. This study compared age verification methods, themes, interactive activities and links to social media across tobacco brand websites. This study examined 12 tobacco brand websites representing four tobacco product categories: cigarettes, cigar/cigarillos, smokeless tobacco, and e-cigarettes. Website content was analyzed by tobacco product category and data from all website visits (n = 699) were analyzed. Adult smokers (n=32) coded websites during a one-year period, indicating whether or not they observed any of 53 marketing themes, seven interactive activities, or five external links to social media sites. Most (58%) websites required online registration before entering, however e-cigarette websites used click-through age verification. Compared to cigarette sites, cigar/cigarillo sites were more likely to feature themes related to "party" lifestyle, and e-cigarette websites were much more likely to feature themes related to harm reduction. Cigarette sites featured greater levels of interactive content compared to other tobacco products. Compared to cigarette sites, cigar/cigarillo sites were more likely to feature activities related to events and music. Compared to cigarette sites, both cigar and e-cigarette sites were more likely to direct visitors to external social media sites. Marketing methods and strategies normalize tobacco use by providing website visitors with positive themes combined with interactive content, and is an area of future research. Moreover, all tobacco products under federal regulatory authority should be required to use more stringent age verification gates. Findings indicate the Food and Drug Administration (FDA) should require brand websites of all tobacco products under its regulatory authority use more stringent age verification gates by requiring all visitors be at least 18 years
