Beyond the Brotherhood: Skoal Bandits' role in the evolution of marketing moist smokeless tobacco pouches.
Background: Since 2006, “snus” smokeless tobacco has been sold in the U.S.. However, U.S. Smokeless Tobacco
(USST) and Swedish Match developed and marketed pouched moist snuff tobacco (MST) since 1973.
Methods: Analysis of previously secret tobacco documents, advertisements and trade press.
Results: USST partnered with Swedish Match, forming United Scandia International to develop pouch products as
part of the “Lotus Project.” Pouched MST was not commonly used, either in Sweden or the U.S. prior to the Lotus Project’s
innovation in 1973. The project aimed to transform smokeless tobacco from being perceived as an “unsightly habit of old
men” into a relevant, socially acceptable urban activity, targeting 15–35 year-old men. While USST’s initial pouched product
“Good Luck,” never gained mainstream traction, Skoal Bandits captured significant market share after its 1983 introduction.
Internal market research found that smokers generally used Skoal Bandits in smokefree environments, yet continued to
smoke cigarettes in other contexts. Over time, pouch products increasingly featured increased flavor, size, nicotine strength
and user imagery variation.
Conclusions: Marlboro and Camel Snus advertising mirrors historical advertising for Skoal Bandits, designed to recruit new
users and smokers subjected to smokefree places. Despite serious efforts, pouched MST marketing has been unable to
dispel its association with traditional smokeless tobacco stereotypes as macho and rural. Public education efforts to
discourage new users and dual use of MST and cigarettes should emphasize that “new” pouch products are simply
repackaging “old” smokeless tobacco
Identification of rice chromosome segment substitution line Z322-1-10 and mapping QTLs for agronomic traits from the F<sub>3</sub> population
Chromosome segment substitution lines (CSSLs) are powerful tools to combine naturally occurring genetic variants with favorable alleles in the same genetic backgrounds of elite cultivars. An elite CSSL Z322-1-10 was identified from advanced backcrosses between a japonica cultivar Nipponbare and an elite indica restorer Xihui 18 by SSR marker-assisted selection (MAS). The Z322-1-10 line carries five substitution segments distributed on chromosomes 1, 2, 5, 6 and 10 with an average length of 4.80 Mb. Spikilets per panicle, 1000-grain weight, grain length in the Z322-1-10 line are significantly higher than those in Nipponbare. Quantitative trait loci (QTLs) were identified and mapped for nine agronomic traits in an F3 population derived from the cross between Nipponbare and Z322-1-10 using the restricted maximum likelihood (REML) method in the HPMIXED procedure of SAS. We detected 13 QTLs whose effect ranging from 2.45% to 44.17% in terms of phenotypic variance explained. Of the 13 loci detected, three are major QTL (qGL1, qGW5-1 and qRLW5-1) and they explain 34.68%, 44.17% and 33.05% of the phenotypic variance. The qGL1 locus controls grain length with a typical Mendelian dominance inheritance of 3:1 ratio for long grain to short grain. The already cloned QTL qGW5-1 is linked with a minor QTL for grain width qGW5-2 (13.01%) in the same substitution segment. Similarly, the previously reported qRLW5-1 is also linked with a minor QTL qRLW5-2. Not only the study is important for fine mapping and cloning of the gene qGL1, but also has a great potential for molecular breeding
Financial Conflicts of Interest and Stance on Tobacco Harm Reduction: A Systematic Review
Background. Tobacco companies have actively promoted the substitution of cigarettes with purportedly safer tobacco products (e.g.,
smokeless tobacco, e-cigarettes) as tobacco harm reduction (THR). Given
the tobacco, e-cigarette, and pharmaceutical industries’ substantial
financial interests, we quantified industry influence on support for THR.
Objectives. To analyze a comprehensive set of articles published in
peer-reviewed journals assessing funding sources and support for or opposition to substitution of tobacco or nicotine products as harm reduction.
Search Methods. We searched PubMed, Embase, Web of Science, and
PsycINFO with a comprehensive search string including all articles,
comments, and editorials published between January 1, 1992 and July 26,
2016.
Selection Criteria. We included English-language publications published
in peer-reviewed journals addressing THR in humans and excluded studies
on modified cigarettes, on South Asian smokeless tobacco variants, on
pregnant women, on animals, not mentioning a tobacco or nicotine
product, on US Food and Drug Administration–approved nicotine replacement therapies, and on nicotine vaccines.
Data Collection and Analysis. We double-coded all articles for article
type; primary product type (e.g., snus, e-cigarettes); themes for and
against THR; stance on THR; THR concepts; funding or affiliation with
tobacco, e-cigarette, pharmaceutical industry, or multiple industries; and
each author’s country. We fit exact logistic regression models with stance
on THR as the outcome (pro- vs anti-THR) and source of funding or industry
affiliation as the predictor taking into account sparse data. Additional
models included article type as the outcome (nonempirical or empirical)
and industry funding or affiliation as predictor, and stratified analyses for
empirical and nonempirical studies with stance on THR as outcome an
Representational predicaments at three Hong Kong sites
Representational predicaments arise when a job incumbent believes that attributions and images assumed by dominant authorities unfavourably ignore, or disproportionately and unfavourably emphasize, aspects of the incumbent\u27s own work and social identity. This is likely to happen when the incumbent does not have a close relationship with a dominant authority, and when power asymmetries give the former relatively little control over which aspects of their work and social identity are made visible or invisible to the latter. We draw on critical incident interviews from three organizations to illustrate a typology of six types of representational predicament: invasive spotlighting, idiosyncratic spotlighting, embedded background work, paradoxical social visibility, standardization of work processes, and standardization of work outputs. We analyse responses to representational predicaments according to whether they entailed exit, voice, loyalty, or neglect. Incumbents tended to respond with loyalty if they felt able and willing to accommodate their work behaviour and/or social identity to the dominant representations, and if there were sufficient compensatory factors, such as intrinsic rewards from the work or solidarity with colleagues. Exit or neglect appeared to reflect the belief that it was impossible to accommodate. Power asymmetries appeared to deter voice. Individual employees with a close and cordial working relationship with a member of a dominant authority group, or who were relationally networked to one, appeared not to experience representational predicaments
Search for a W' boson decaying to a bottom quark and a top quark in pp collisions at sqrt(s) = 7 TeV
Results are presented from a search for a W' boson using a dataset
corresponding to 5.0 inverse femtobarns of integrated luminosity collected
during 2011 by the CMS experiment at the LHC in pp collisions at sqrt(s)=7 TeV.
The W' boson is modeled as a heavy W boson, but different scenarios for the
couplings to fermions are considered, involving both left-handed and
right-handed chiral projections of the fermions, as well as an arbitrary
mixture of the two. The search is performed in the decay channel W' to t b,
leading to a final state signature with a single lepton (e, mu), missing
transverse energy, and jets, at least one of which is tagged as a b-jet. A W'
boson that couples to fermions with the same coupling constant as the W, but to
the right-handed rather than left-handed chiral projections, is excluded for
masses below 1.85 TeV at the 95% confidence level. For the first time using LHC
data, constraints on the W' gauge coupling for a set of left- and right-handed
coupling combinations have been placed. These results represent a significant
improvement over previously published limits.Comment: Submitted to Physics Letters B. Replaced with version publishe
Search for the standard model Higgs boson decaying into two photons in pp collisions at sqrt(s)=7 TeV
A search for a Higgs boson decaying into two photons is described. The
analysis is performed using a dataset recorded by the CMS experiment at the LHC
from pp collisions at a centre-of-mass energy of 7 TeV, which corresponds to an
integrated luminosity of 4.8 inverse femtobarns. Limits are set on the cross
section of the standard model Higgs boson decaying to two photons. The expected
exclusion limit at 95% confidence level is between 1.4 and 2.4 times the
standard model cross section in the mass range between 110 and 150 GeV. The
analysis of the data excludes, at 95% confidence level, the standard model
Higgs boson decaying into two photons in the mass range 128 to 132 GeV. The
largest excess of events above the expected standard model background is
observed for a Higgs boson mass hypothesis of 124 GeV with a local significance
of 3.1 sigma. The global significance of observing an excess with a local
significance greater than 3.1 sigma anywhere in the search range 110-150 GeV is
estimated to be 1.8 sigma. More data are required to ascertain the origin of
this excess.Comment: Submitted to Physics Letters
