O trabalho sexual online com recurso a plataformas de distribuição de conteúdo: um estudo exploratório
A expansão da Internet e da sua utilização levaram a transformações a todos os
níveis e a indústria do sexo não foi exceção com o surgimento do trabalho sexual online,
que engloba diversas formas de o executar, incluindo o recurso a plataformas de
distribuição de conteúdo. Ainda que este seja um fenómeno crescente, a literatura
científica não tem acompanhado essa tendência, deixando este tema por explorar e as
vozes dos seus intervenientes por ouvir. Assim, para dar um contributo para colmatar a
lacuna na investigação acerca deste tópico, principalmente no contexto nacional, este
estudo exploratório pretendeu descrever, explorar e compreender a utilização de
plataformas de distribuição de conteúdo para a realização de trabalho sexual online. Para
tal, foram realizadas dez entrevistas semiestruturadas a mulheres que recorrem a
plataformas de distribuição de conteúdo para a realização de trabalho sexual online, com
idades compreendidas entre os 19 e os 37 anos. Estas foram analisadas através do recurso à
análise de conteúdo temática, da qual surgiram seis temas: caracterização do trabalho
sexual online; trajetórias no trabalho sexual online; riscos e benefícios; consequências da
realização do trabalho sexual online; clientes. Concluiu-se que o contexto do trabalho
sexual online se pauta por diversidade em todas as suas dimensões, influenciando as
mulheres que o desempenham em diferentes aspetos da sua vida. Também os clientes são
descritos como um grupo heterogéneo, motivados principalmente pela procura de
autenticidade e intimidade. Além disso, o estigma apresenta-se como algo que exerce uma
intensa pressão nas pessoas que desempenham trabalho sexual online, afetando-as nos
níveis pessoal, das relações interpessoais e, ainda, no que toca ao emprego e ensino,
devido, em grande parte, à dualidade promiscuidade-vitimação através da qual são vistas.
O presente estudo parece colmatar a falta de conhecimento e investigação científica
sobre este fenómeno emergente, compreendendo o modo de funcionamento desta indústria
e as perceções e vivências de quem nela participa, procurando dar voz e empoderar esta
população. Esperamos que esta investigação permita, assim, impulsionar novas
investigações na área e promover uma redução do estigma face a quem realiza trabalho
sexual online, diminuindo a sua influência negativa
Cross-cultural adaptation of the Tailored Activity Program (TAP) for Brazilian Portuguese
Introduction: The Tailored Activity Program (TAP) is an intervention program in Occupational Therapy for individuals with dementia and their caregivers. It is based on 8 home-based sessions, during 3 or 4 months. Brazil lacks an Occupational Therapy methodology of action, which justifies the cross-cultural adaptation of the TAP. Objective: To adapt the TAP reference materials "Intervention Manual" and the "Caregiver Notebook" to the Brazilian culture. Method: The methodology used proposes the translation, back translation, evaluation of semantic, idiomatic, conceptual and cultural equivalences and the pre-test of materials for production in Portuguese. Results: The translation phase adapted 17 itemsthe back-translation process identified distortions. In the evaluation of the semantic and idiomatic equivalence of the Manual Intervention, 74 items of 374 items evaluated were discordantand in the Caregivers Notebook 96 items of 2051 items evaluated were discordant. Regarding to conceptual and cultural equivalence, in the Manual Intervention, 62 of 374 items evaluated were discordant and in the Caregivers Notebook, 57 of 2051 items. The discordant items were modified from suggestions given by the reviewers. After the evaluation of the committee of reviewers, we conducted a pre-test of the Portuguese versions and two items were adapted. Conclusion: The TAP has been adapted to the Brazilian culture and kept the original proposal for intervention with 8 sessions during a period of 3 to 4 months.Univ Fed Sao Paulo Unifesp, Dept Gestao & Cuidados Saude, Baixada Santista, SP, BrazilJohns Hopkins Univ, Sch Nursing, Ctr Innovat Care Aging, Baltimore, MD USAUniv Fed Sao Paulo Unifesp, Dept Gestao & Cuidados Saude, Baixada Santista, SP, BrazilWeb of Scienc
The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe
The preponderance of matter over antimatter in the early Universe, the
dynamics of the supernova bursts that produced the heavy elements necessary for
life and whether protons eventually decay --- these mysteries at the forefront
of particle physics and astrophysics are key to understanding the early
evolution of our Universe, its current state and its eventual fate. The
Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed
plan for a world-class experiment dedicated to addressing these questions. LBNE
is conceived around three central components: (1) a new, high-intensity
neutrino source generated from a megawatt-class proton accelerator at Fermi
National Accelerator Laboratory, (2) a near neutrino detector just downstream
of the source, and (3) a massive liquid argon time-projection chamber deployed
as a far detector deep underground at the Sanford Underground Research
Facility. This facility, located at the site of the former Homestake Mine in
Lead, South Dakota, is approximately 1,300 km from the neutrino source at
Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino
charge-parity symmetry violation and mass ordering effects. This ambitious yet
cost-effective design incorporates scalability and flexibility and can
accommodate a variety of upgrades and contributions. With its exceptional
combination of experimental configuration, technical capabilities, and
potential for transformative discoveries, LBNE promises to be a vital facility
for the field of particle physics worldwide, providing physicists from around
the globe with opportunities to collaborate in a twenty to thirty year program
of exciting science. In this document we provide a comprehensive overview of
LBNE's scientific objectives, its place in the landscape of neutrino physics
worldwide, the technologies it will incorporate and the capabilities it will
possess.Comment: Major update of previous version. This is the reference document for
LBNE science program and current status. Chapters 1, 3, and 9 provide a
comprehensive overview of LBNE's scientific objectives, its place in the
landscape of neutrino physics worldwide, the technologies it will incorporate
and the capabilities it will possess. 288 pages, 116 figure
Multidifferential study of identified charged hadron distributions in -tagged jets in proton-proton collisions at 13 TeV
Jet fragmentation functions are measured for the first time in proton-proton
collisions for charged pions, kaons, and protons within jets recoiling against
a boson. The charged-hadron distributions are studied longitudinally and
transversely to the jet direction for jets with transverse momentum 20 GeV and in the pseudorapidity range . The
data sample was collected with the LHCb experiment at a center-of-mass energy
of 13 TeV, corresponding to an integrated luminosity of 1.64 fb. Triple
differential distributions as a function of the hadron longitudinal momentum
fraction, hadron transverse momentum, and jet transverse momentum are also
measured for the first time. This helps constrain transverse-momentum-dependent
fragmentation functions. Differences in the shapes and magnitudes of the
measured distributions for the different hadron species provide insights into
the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any

European Society of Cardiology: Cardiovascular Disease Statistics 2019
Aims The 2019 report from the European Society of Cardiology (ESC) Atlas provides a contemporary analysis of cardiovascular disease (CVD) statistics across 56 member countries, with particular emphasis on international inequalities in disease burden and healthcare delivery together with estimates of progress towards meeting 2025 World Health Organization (WHO) non-communicable disease targets. Methods and results In this report, contemporary CVD statistics are presented for member countries of the ESC. The statistics are drawn from the ESC Atlas which is a repository of CVD data from a variety of sources including the WHO, the Institute for Health Metrics and Evaluation, and the World Bank. The Atlas also includes novel ESC sponsored data on human and capital infrastructure and cardiovascular healthcare delivery obtained by annual survey of the national societies of ESC member countries. Across ESC member countries, the prevalence of obesity (body mass index ≥30 kg/m2) and diabetes has increased two- to three-fold during the last 30 years making the WHO 2025 target to halt rises in these risk factors unlikely to be achieved. More encouraging have been variable declines in hypertension, smoking, and alcohol consumption but on current trends only the reduction in smoking from 28% to 21% during the last 20 years appears sufficient for the WHO target to be achieved. The median age-standardized prevalence of major risk factors was higher in middle-income compared with high-income ESC member countries for hypertension {23.8% [interquartile range (IQR) 22.5–23.1%] vs. 15.7% (IQR 14.5–21.1%)}, diabetes [7.7% (IQR 7.1–10.1%) vs. 5.6% (IQR 4.8–7.0%)], and among males smoking [43.8% (IQR 37.4–48.0%) vs. 26.0% (IQR 20.9–31.7%)] although among females smoking was less common in middle-income countries [8.7% (IQR 3.0–10.8) vs. 16.7% (IQR 13.9–19.7%)]. There were associated inequalities in disease burden with disability-adjusted life years per 100 000 people due to CVD over three times as high in middle-income [7160 (IQR 5655–8115)] compared with high-income [2235 (IQR 1896–3602)] countries. Cardiovascular disease mortality was also higher in middle-income countries where it accounted for a greater proportion of potential years of life lost compared with high-income countries in both females (43% vs. 28%) and males (39% vs. 28%). Despite the inequalities in disease burden across ESC member countries, survey data from the National Cardiac Societies of the ESC showed that middle-income member countries remain severely under-resourced compared with high-income countries in terms of cardiological person-power and technological infrastructure. Under-resourcing in middle-income countries is associated with a severe procedural deficit compared with high-income countries in terms of coronary intervention, device implantation and cardiac surgical procedures. Conclusion A seemingly inexorable rise in the prevalence of obesity and diabetes currently provides the greatest challenge to achieving further reductions in CVD burden across ESC member countries. Additional challenges are provided by inequalities in disease burden that now require intensification of policy initiatives in order to reduce population risk and prioritize cardiovascular healthcare delivery, particularly in the middle-income countries of the ESC where need is greatest
Branching Fraction Measurements of the Rare and Decays
The branching fraction of the rare decay is measured using data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to integrated luminosities of 1, 2, and 6 fb, respectively. The branching fraction is reported in intervals of q, the square of the dimuon invariant mass. In the q region between 1.1 and 6.0 GeV/c, the measurement is found to lie 3.6 standard deviations below a standard model prediction based on a combination of light cone sum rule and lattice QCD calculations. In addition, the first observation of the rare decay is reported with a statistical significance of 9 standard deviations and its branching fraction is determined
