    Charmonium Production at Forward Rapidity in pp, p-Pb and Pb-Pb Collisions, with ALICE

    Full text link
    This contribution focuses on latest ALICE results on charmonium forward production in proton-proton (pp), proton-lead (p-Pb) and lead-lead (Pb-Pb) collisions at the TeV scale. In p-Pb and Pb-Pb collisions, measurements are presented in the form of the charmonium nuclear modification factor (the properly normalized ratio of its production cross section in heavy ion collisions to its pp counterpart) as a function of the charmonium rapidity and transverse momentum. These measurements are compared to available theoretical calculations. Possible interpretations of these results in terms of gluon saturation, initial and final state energy loss, color screening and recombination are also discussed.Comment: 6 pages, 11 figures, Conference Proceedings Large Hadron Collider Physics (LHCP) Conference, 201

    Women in Resistance: Reporting the impact of IEEEWiEUFRNexhibition at Science and Tech Week at UFRN

    In celebration of the 60th anniversary of UFRN, we have proposed an initiative by IEEE WiEUFRNat CIENTEC aiming to highlight the female contribution to the STEM (Science, Technology, Engineering and Maths) degrees at UFRN over the last 60 years. The highlights were made through an exhibition, composed of four parts: I) description of renowned female icons and their contributions to the STEM areas. II) History of female participation in STEM courses at UFRN, through graphs showing the percentage of female students in the courses since its creation. III) #euexisto campaign: display of testimonials videos from current students of STEM courses explaining why they chose the course. IV) Tribute to female Lecturers: display all female lecturersnames that have taught in STEM courses at UFRN. As a result, the group paida tribute to those brilliant women and highlighted their contribution to STEM;acknowledged the current students and teachers of the courses; and helped raising awareness about the need to encourage the participation of women in these courses and in order to build a more diverse environment. Our main goal was raise awareness that the degrees of STEM had consistently less women than man and thus, our feminist group had a very important role to play in increasing those numbers. From the informal feedback we received, we believe our goal was achieved

    Sacrifice and Efficiency of the Income Tax Schedule

    We investigate the efficiency of equal sacrifice tax schedules in an economywhich primitives are exactly those in Mirrlees (1971): a continuum of individualswith identical preferences defined over consumption and leisure who differ withrespect to their labor market productivity. Using a separable specification forpreferences we derive the minimum equal sacrifice allocation and recover thetax schedule that implements it. The separable specification allows us to usethe methodology developed by Werning (2007b) to check whether the scheduleis efficient, that is, whether there is no alternative tax schedule that raises morerevenue while delivering less utility to no one. We find that inefficiency does notarise for most parametrizations we use to approximate the US economy. For thefew cases for which inefficiency does arise, it does so only for very high levels ofincome and marginal tax rates.

    In-medium formation of quarkonium

    Get PDF
    We confront preliminary RHIC data on J/Psi production in nuclear interactions with expectations which follow in scenarios involving charm quark recombination in a region of color deconfinement. The focus is on transverse momentum and rapidity spectra of the J/Psi, which carry a memory of the spectra of the charm quarks. In such a scenario, one predicts that both spectra will be narrower than those expected without recombination. Preliminary results for the transverse momentum spectra point toward a preference for the recombination picture, while the rapidity spectra do not exhibit any narrowing within present large uncertainties. We present new calculations in the recombination model for the centrality behavior of these signals, which map out the necessary experimental precision required for a definitive test.Comment: Based on invited talk at Strangeness in Quark Matter 2006, UCLA, March 26-31, 2006.

    INVESTIGACIÓN Y DESARROLLO TERRITORIAL Dimensiones de la relación entre intereses científicos y demandas locales en el área de influencia de la Universidad Nacional de Luján.

    En esta ponencia se manifiesta que el desarrollo territorial es un ámbito apropiado para evaluar el proceso de investigación y producción de conocimientos. Desde el interjuego de variables generales tales como: configuración socioeconómica territorial, intereses y demandas de la sociedad, y políticas de investigación de la Universidad Nacional de Luján (UNLu), se busca caracterizar y dimensionar la relación entre conocimiento construido en los distintos departamentos de la universidad y la resolución de problemáticas locales. Se intenta sentar bases para identificar problemas y reformular políticas de investigación a partir de: a. Configurar la situación socioeconómica territorial del área de influencia de la UNLu. para detectar problemas. b. Identificar los intereses y demandas de los distintos sectores de la sociedad involucrada. c. Inventariar los proyectos de investigación desarrollados en la UNLu. desde 1995. d. Reconocer las ideas que actuaron como mapas de rutas para la definición de las políticas de investigación. e. Visualizar la relación entre intereses de la comunidad e ideas que perfilaron los proyectos de investigación. f. Establecer el nivel de correspondencia con el plan estratégico nacional de mediano plazo en ciencia, tecnología e innovación y los indicadores de ciencia y tecnología interamericana / iberoamericana

    Drivers and barriers to physiotherapists' involvement in healthcare management and leadership roles, in Portugal

    Get PDF
    Within the changes in the Portuguese healthcare system across the years, new challenges emerge for healthcare practitioners, organizations, and their management boards, so the recognition of the need for different health professionals in Healthcare Management has been growing. However, physiotherapists’ core responsibilities remain rooted on therapeutic practices and rehabilitation, developed primarily in clinical and hospital environments. Regarding this scenario, physiotherapists’ functions continue to be absent to the highest Healthcare Management and Leadership positions, despite their knowledge and understanding about how to ensure the best services to the patients. As such, this investigation aimed to deepen the drivers and barriers to physiotherapists’ involvement in Healthcare Management and Leadership roles, in Portugal. For such, a crosssectional survey was performed with 287 physiotherapists that performed their activity in Portugal, carrying out both quantitative and qualitative data collection. Findings suggest that a lack of training and existent policies and laws are evident barriers to the access of both Healthcare Management and Leadership positions. In turn, networking as well as soft skills development, are considered drivers to these roles, amongst other factors.No âmbito das mudanças no sistema de saúde português ao longo dos anos, novos desafios têm surgido para os profissionais de saúde, as organizações e os seus órgãos de gestão, pelo que tem vindo a crescer o reconhecimento da necessidade de diferentes profissionais de saúde na Gestão das suas unidades. No entanto, as principais responsabilidades dos fisioterapeutas permanecem enraizadas nas práticas terapêuticas e de reabilitação, desenvolvidas principalmente em ambientes clínicos e hospitalares. Perante este cenário, o fisioterapeuta continua ausente dos cargos mais elevados de Gestão e Liderança em Saúde, apesar do seu vasto conhecimento e compreensão acerca da prestação dos melhores cuidados de saúde aos pacientes. Como tal, esta investigação teve como objetivo aprofundar os facilitadores e as barreiras ao envolvimento dos fisioterapeutas em cargos de Gestão da Saúde e Liderança, em Portugal. Para tal, foi realizado um estudo descritivo transversal com 287 fisioterapeutas que exercem a sua atividade em Portugal, efetuando uma recolha de dados quantitativa e qualitativa. Os resultados sugerem que a falta de formação e as políticas e leis existentes são barreiras evidentes ao acesso dos fisioterapeutas a cargos de Gestão de Saúde e de Liderança. Por sua vez, a networking (rede de contactos), assim como o desenvolvimento de soft-skills, são considerados facilitadores para o envolvimento destes profissionais nessas funções, entre outros fatores
