PRICE TRANSMISSION ON THE MILK PORTUGUESE MARKET

This paper aims to analyze the milk prices transmission along the food chain in Portugal, temporally and spatially. The analysis will be carried out with feed prices, farm gate milk prices and with the index prices of package milk out of factory. The results show that the volatility on retail prices is small but after 2008 the prices outside industry show a real increase. Beside that evolution, farm gate price does not change when the price of package milk changes. In mainland, price transmission from retail to farm price does not happen but for Azores the transmission is effective. In the intensive systems, the risk to collapse is bigger than in the extensive systems, where the volatility of prices reflects the process of markets adjustment to changes in supply and demand conditions

Visita domiciliar em um condomínio de idosos como instrumento para atenção e cuidado integral à saúde / Home visit in an elderly condominium as an instrument for integral health care and care

O envelhecimento humano é um fenômeno natural, social e irreversível. É dever do Estado a garantia do envelhecimento saudável e com condições dignas. O presente estudo tem como objetivo descrever as experiências dos estudantes de medicina em um condomínio de idosos através da visita domiciliar, além de reconhecer as principais necessidades em saúde, fazer intervenções educacionais com ênfase na saúde, a fim de garantir a atenção e cuidado integral ao idoso. Trata-se de um estudo descritivo, qualitativo, com abordagem direta e observacional na modalidade Relato de Experiência. O registro de dados ocorreu por meio de fontes escritas, orais e imagéticas, no período de setembro e outubro de 2019. O idoso tem particularidades que impactam a qualidade de vida, visto que possuem maiores índices de doenças crônicas e fragilidades, mais custos para a saúde, menos recursos sociais e financeiros. Envelhecer, sem a devida assistência é um desafio. Com tantas condições desafiadoras, faz-se indispensável aproximar-se do cuidado do idoso por meio das visitas domiciliares. Assim, foi possível planejar atividades que envolvessem a coletividade, destacou-se a importância dos idosos se relacionarem e dialogar mais entre si. A visita domiciliar proporcionou benefícios mútuos. É imprescindível a ampliação da proteção social da pessoa idosa, a fim de garantir a qualidade de vida e um envelhecimento saudável. Não menos importante é a necessidade da construção do vínculo, visto que se torna mais fácil desenvolver um trabalho que contemple, ao máximo, a necessidade de quem carece do cuidado

A Structural Equations Modeling Approach

COVID-19 vaccine hesitancy (VH) has caused concerns due to the possible fluctuations that may occur directly impacting the control of the pandemic. In this study, we aimed to estimate the prevalence and factors associated with COVID-19 VH in Portuguese-speaking countries. We developed a web survey (N:6,843) using an online, structured, and validated questionnaire. We used Measurement Models, Exploratory Factor Analysis, Exploratory Structural Equation Models, and Confirmatory Factor Analysis for the data analysis. The overall prevalence of COVID-19 VH in Portuguese-speaking countries was 21.1%. showed a statistically significant direct effect for VH: vaccine-related conspiracy beliefs (VB) (β = 0.886), perceived stress (PS) (β = 0.313), COVID-19 Misinformation (MIS) (β = 0.259) and individual responses to COVID-19 (CIR) (β = −0.122). The effect of MIS and CIR for VH was greater among men and of PS and VB among women; the effect of PS was greater among the youngest and of VB and CIR among the oldest. No discrepant differences were identified in the analyzed education strata. In conclusion, we found that conspiracy beliefs related to the vaccine strongly influence the decision to hesitate (not to take or to delay the vaccine). Specific characteristics related to gender, age group, social and cognitive vulnerabilities, added to the knowledge acquired, poorly substantiated and/or misrepresented about the COVID-19 vaccine, need to be considered in the planning of vaccination campaigns. It is necessary to respond in a timely, fast, and accurate manner to the challenges posed by vaccine hesitancy.publishersversionpublishe

Factors Associated with Emotion Regulation in Men with Internet Access Living in Brazil during the COVID-19 Pandemic

Publisher Copyright: © 2022 by the authors. Licensee MDPI, Basel, Switzerland.Objective: to evaluate the factors associated with emotion regulation in men with internet access living in Brazil during the COVID-19 pandemic. Method: an epidemiological survey, conducted with 1015 men. An electronic form was applied containing sociodemographic and occu-pational characteristics, support and coping strategies, as well as emotional and behavioral aspects. Emotion regulation was assessed using the Emotion Regulation Questionnaire. Results: The prevalence values observed were 44.6% for Low Cognitive Reappraisal and of 47.1% for High Emotional Sup-pression. The following factors were identified as associated: (a) with Low Cognitive Reappraisal: being aged 30 years old or more, practicing physical activity, worrying about social distancing and having positive emotions and feelings; and (b) with High Emotional Suppression: being heterosexual, non-white race/skin color, having security support or public administration, not sanitizing food, worrying about lack of physical activity and not having negative emotions. Conclusion: the adoption of emotion regulation strategies was associated with individual, contextual and emotional/behavioral characteristics. Masculinity ideals seem to exert an influence on these relationships.publishersversionpublishe

MENOPAUSA E SUAS CONSEQUÊNCIAS PSICOLÓGICAS.

Introduction: Menopause, a natural stage in women's lives, marks the end of the reproductive period and is often accompanied by hormonal and physical changes. Furthermore, menopause can have significant implications for women's mental health, influencing their emotional and psychological states. Objective: This study aims to investigate the psychological consequences of menopause in women, exploring the emotional and behavioral impacts associated with this transition phase. Methodology: This is an integrative literature review, with an approach that allows the synthesis of studies with different methodologies, including qualitative, quantitative and mixed studies. Searches were carried out in electronic databases, such as PubMed, PsycINFO and Scopus, using keywords related to menopause and mental health. Studies published in the last 10 years were selected. Results: The results highlighted a variety of psychological consequences related to menopause. Many participants reported symptoms of anxiety, depression and mood swings. In addition, self-esteem and body image were affected in some cases. Quality of life was also perceived as compromised due to these emotional challenges. Final Considerations: The study highlights the importance of understanding the psychological implications of menopause and recognizing that this phase can be accompanied by significant emotional difficulties for some women. The multidimensional approach, which considers both the biological and psychological aspects of menopause, is essential to provide adequate support to women in this transition.Introdução: A menopausa, um estágio natural na vida de mulheres, marca o fim do período reprodutivo e é frequentemente acompanhada por mudanças hormonais e físicas.

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio

Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS

The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb^-1, these states are reconstructed through their radiative decays to Upsilon(1S,2S) with Upsilon->mu+mu-. In addition to the mass peaks corresponding to the decay modes chi_b(1P,2P)->Upsilon(1S)gamma, a new structure centered at a mass of 10.530+/-0.005 (stat.)+/-0.009 (syst.) GeV is also observed, in both the Upsilon(1S)gamma and Upsilon(2S)gamma decay modes. This is interpreted as the chi_b(3P) system.Comment: 5 pages plus author list (18 pages total), 2 figures, 1 table, corrected author list, matches final version in Physical Review Letter

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters
