A global model study of natural bromine sources and the effects on tropospheric chemistry using MOZART4

Halogens in the atmosphere chemically destroy ozone. In the troposphere, bromine has higher ozone destruction efficiency than chlorine and is the halogen species with the widest geographical spread of natural sources. We investigate the relative strength of various sources of reactive tropospheric bromine and the influence of bromine on tropospheric chemistry using a 6-year simulation with the global chemistry transport model MOZART4. We consider the following sources: short-lived bromocarbons (CHBr3, CH2BrCl, CHBr2Cl, CHBrCl2, and CH2Br2) and CH3Br, bromine from airborne sea salt particles, and frost flowers and sea salt on or in the snowpack in polar regions. The total bromine emissions in our simulations add up to 31.7Gmol(Br)/yr: 63% from polar sources, 24.6% from short-lived bromocarbons and 12.4% from airborne sea salt particles. We conclude from our analysis that our global bromine emission is likely to be on the lower end of the range, because of too low emissions from airborne sea salt. Bromine chemistry has an effect on the oxidation capacity of the troposphere, not only due to its direct influence on ozone concentrations, but also by reactions with other key chemical species like HO x and NO x . Globally, the impact of bromine chemistry on tropospheric O3 is comparable to the impact of gas-phase sulfur chemistry, since the inclusion of bromine chemistry in MOZART4 leads to a decrease of the O3 burden in the troposphere by 6Tg, while we get an increase by 5Tg if gas-phase sulfur chemistry is switched off in the standard model. With decreased ozone burden, the simulated oxidizing capacity of the atmosphere decreases thus affecting species associated with the oxidation capacity of the atmosphere (CH3OOH, H2O2

Evidências métricas da adaptação da escala de inteligência cultural numa amostra portuguesa

Validating the Cultural Intelligence Scale (CQS) for the Portuguese population was the main objective of this study. Cultural Intelligence is recognized as a crucial competence in multicultural situations. The multidimensional cultural intelligence scale is composed of 20 items arranged into four dimensions and is used to evaluate the individual characteristics that predispose to better performance in unfamiliar cultural environments. The results from the analysis of main components in a total sample of 275 participants, aged between 18 and 72 (M = 29.3; SD = 12.9), replicated the original ones, therefore showing good validity values and internal consistency (Cronbach alpha .93), revealing the multidimension of the evaluated construct. Once the exploratory analysis replicated the model tested by the confirmatory analysis, the application of this instrument in multicultural organizational contexts can be considered an essential tool, not only to identify crucial capacities for the functioning of the human resources, teams or organizations in environments characterized by cultural diversity, but also to ensure the success in the integration processes of immigrants and expatriates.Este estudo teve como principal objetivo a validação da Cultural Intelligence Scale (CQS) para a população portuguesa. A inteligência cultural é uma competência crucial na adaptação a ambientes multiculturais. A escala multidimensional de inteligência cultural é composta por 20 itens agrupados em quatro dimensões e permite avaliar as características individuais que predispõem um melhor desempenho em ambientes culturais não familiares. Com uma amostra total de 275 participantes, com idades compreendidas entre os 18 e os 72 anos (M = 29,3; DP = 12,9), os resultados obtidos através da realização da análise de componentes principais replicaram os resultados originais, apresentando bons valores de validade e consistência interna (alfa de Cronbach de 0,93), revelando a multidimensionalidade do construto avaliado. A análise exploratória replicou o modelo testado pela análise confi rmatória. Assim, a aplicação deste instrumento em contexto organizacional multicultural poderá ser uma ferramenta fundamental para identifi car competências cruciais ao desempenho dos recursos humanos, equipas ou organizações, em ambientes caracterizados pela diversidade cultural, assim como, garantir o sucesso dos processos de integração de expatriados e de imigrantes.

The influence of authentic leadership on public employees analyzed through self- determination theory: a case study in Republic of Moldova

This study examines the influence of authentic leadership on employees from public organizations analyzed through self-determination theory. Over the years, researchers analyzed different particularities of authentic leadership and its importance in nowadays' society. However, fewer researchers were interested in analyzing the influence of authentic leadership on employees through self-determination theory, especially in the perception of public ethical behavior. The theoretical model of this study proposes that authentic leadership is negatively correlated with public employees' positive attitude toward unethical behavior, namely corrupt acts. Also, authentic leadership and job satisfaction are positively related with public employees' work motivation. This positive relationship contributes to the decrease level of public employees' positive attitude toward corruption acts. The study was realized in different public organizations from Republic of Moldova. The total sample is composed by 98 participants. The hypotheses were tested through Multiple Hierarchical Regression. The study results showed that authentic leadership has a positive impact on work motivation. However, job satisfaction does not have any influence on public employees' perception of corruption acts. By contrast, authentic leadership behavior does have a positive impact on public employees' perception of corruption acts, but only when they perceive these acts as less serious

Are we getting less sexist? a ten-year gap comparison analysis of sexism in a Portuguese sample

Widely and slowly, discrimination against women based upon gender has become socially unacceptable. However, less is known about how sexist beliefs have progressed in the last years and if we are responding to this social antagonizing of a sexist discourse. Our goal was to verify the existence of differences in ambivalent sexism and neosexism over a ten-year gap in a Portuguese adult sample and to assess possible modifications in the relationship between the variables. A cross-sectional, correlational study was conducted using two independent groups, with measures taken in 2009 and then in 2019. Both groups were invariant in terms of average age and proportion of sexes. Our results show a decrease in hostile and benevolent forms of sexism, while neosexism remains constant. The relationships between variables suggest that sexist beliefs are changing to accommodate subtler and modernized forms of sexism, like neosexism, that deny the existence of discrimination against women, resent discrimination complaints, and maintain a paternalistic view of women. Neosexism also seems to have a stronger correlation with hostile sexism than with benevolent forms of sexism in the male subsample. This relationship is stronger for the 2019 sample. These relationships suggest that sexism is more deeply rooted than we would like to admit and adapts to social discourse. Despite our best efforts, it is yet to be overcome.info:eu-repo/semantics/publishedVersio

# 003. Técnica cirúrgica de tunelização para recobrimento gengival de recessões

Introdução: Uma recessão pode ser definida pela retração apical da gengiva, podendo ser provocada por técnica traumática de escovagem, movimentos ortodônticos, hábitos parafuncionais e doença periodontal. Para este tipo de lesões, é possível recorrer a técnicas de cirurgia plástica periodontal usando enxertos de tecido conjuntivo, tendo como objetivo aumentar a quantidade de tecido queratinizado e permitir a cobertura da raiz exposta. Há várias técnicas possíveis de serem usadas, como a técnica da tunelização com enxertos de tecido conjuntivo subepitelial colocados coronalmente. Descrição do caso clínico: Paciente do sexo feminino, 25 anos, saudável. Não fumadora, com diagnóstico de gengivite leve (índice de placa de 15% e índice de sangramento de 8%) e recessões classe I de Miller em todos os sextantes por vestibular, perda de inserção gengival de 3 mm no dente 23 e 2 mm no 24. No plano de tratamento optou‐se pela cirurgia plástica periodontal, pela técnica de tunelização nos dentes 23 e 24 e alongamento coronário por gengivectomia no dente 11. Foi administrada anestesia infiltrativa local no palato e no vestíbulo. Foram realizadas incisões sulculares nos dentes envolvidos, criando um túnel subperiósteo. Criou‐se um retalho de espessura total que se estendeu apicalmente além da linha mucogengival. Na zona interdentária, o retalho foi estendido coronalmente à base das papilas. Foi recolhido tecido conjuntivo subepitelial no palato de tamanho suficiente para cobrir as zonas com defeito. O enxerto foi colocado no túnel subperiósteo e realizadas suturas de forma a estabilizar os enxertos no retalho gengival, com fios de sutura 6‐0. Na região do palato, foi colocado PeriAcryl. À paciente foi prescrita medicação analgésica e anti‐inflamatória, bochecho com 0,2% de clorohexidina digluconato e visitas de controlo. Duas semanas após a cirurgia, foram removidas as suturas. Discussão e conclusões: Após uma cirurgia periodontal, é importante evitar recidivas e fomentar mudanças comportamentais, como na escovagem dos dentes, e técnica e força utilizadas. Apesar disso, o alinhamento dentário é de igual interesse, podendo ser necessária a correção ortodôntica em casos de mau posicionamento dentário. A técnica de tunelização descrita tem demonstrado bons resultados pós‐operatórios, pois elimina a necessidade de incisões verticais, protege a altura da papila e otimiza a vascularização.info:eu-repo/semantics/publishedVersio

The psychometric properties of the adolescent dissociative experiences scale (A-DES) in a sample of Portuguese at-risk adolescents

Dissociation is a process that often occurs as a sequela of psychological trauma, and it is interrelated with psychological and behavioral problems. In the at-risk adolescent population, dissociation is often underdiagnosed and undertreated. Having reliable measures to assess this phenomenon can help in identifying adolescents at-risk and improve treatment outcomes. This study assessed the psychometric properties of the Adolescent Dissociative Experiences Scale (A-DES) with a sample of 402 Portuguese adolescents recruited from three at-risk populations. Participants completed self-report measures of trauma exposure, posttraumatic symptoms, psychological and behavioral problems, and the A-DES. A subset of the sample also completed test-retest measures. Confirmatory factor analyses revealed a best-fitting 3-factor model. Analyses revealed good internal consistencies and good agreement test-retest reliability for the scale overall and the factor-based sub-scales. Construct and predictive validity was supported with results showing that A-DES discriminates between youth reporting high versus low levels of cumulative trauma exposure and youth who meet or do not meet criteria for a probable PTSD diagnosis. Study findings replicate prior research supporting a 3-factor model of dissociation and the usefulness of A-DES to identify adolescents with dissociative symptoms. Clinical and research implications are discussed.This study was conducted at the Psychology Research Centre (CIPsi/UM) School of Psychology, University of Minho, supported by the Foundation for Science and Technology (FCT) through the Portuguese State Budget (UIDB/01662/2020), as well as through the funding of a research grant awarded to the first author;Foundation for Science and Technology [SFRH/BD/129194/2017,UIDB/01662/2020]
