Dear All,
Our colleagues Burcu Taskan and Vanda Ramos will be presenting their PhD follow up. Please find below the Zoom link, if needed, as well as the titles and abstracts for their presentation.
Burcu will be presenting by Zoom and Vanda will do her presentation in Portuguese. So, for those who are not fluent or native in Portuguese, it is always a good opportunity to learn a little bit more.

Title: Challenges to Cope with Uncertainty
in Work Settings: Psychological Mechanisms and Contextual Moderators
Abstract: In the last few decades, the organizational environment has been frequently described through the acronym VUCA, that stands for a volatile, uncertain, complex, and ambiguous environment. In this presentation, four thesis studies will be presented. In the first study, the main aim is ensuring a review of the literature to clarify a conceptual map of VUCA components and their relations to highlight some avenues for future research. Despite the popularity of that acronym, it is common to find in the literature some overlapping regarding the meaning of those terms as well as ill-definitions of each one. In the second study, the main aim is analyzing the mediating role of perceived effects of telework on adaptive performance via negative affect, and to test whether this indirect effect would be moderated by the leadership effectiveness with a cross-sectional design. The aim of the third study is analyzing the uncertainty and adaptive performance with a multilevel analysis of a diary data. The last study is a longitudinal study by investigating the perceived effects of hybrid work model on performance, productivity, and well-being with a multilevel analysis of a diary data.

Título: Stress e saúde física nas zungueiras dos mercados informais na cidade de Luanda-Angola. Um estudo quantitativo
Resumo: Esta investigação visa: (a) identificar os principais fatores de stress das zungueiras; (b) comparar os níveis de stress entre as zungueiras que trabalham na rua e as que trabalham na praça e (c) avaliar a ligação do stress a problemas de saúde. Recolheram-se os dados a 252 zungueiras de Luanda através de questionário, onde se pedia: a avaliação da importância dos princiapis fatores de stress identificados num estudo qualitativo; a avaliação dos problemas de saúde das zungueiras usando escalas validadas. A análise fatorial em componentes principais identificou quatro fatores de stress: F1 – “Problemas com as autoridades” (7 itens, alfa=0,89; M= 4,55; DP=0,62); F2 – “Insegurança” (7 itens; alfa=0,81; M= 2,92; DP=0,90); F3 – “Más condições físicas de trabalho” (4 itens; alfa=0,76; M= 3,83; DP=0,87) e o F4 – “Falta de rendimento” (4 itens; alfa=0,70; M= 3,87; DP=0,78). As zungueiras que trabalham na rua apresentam níveis significativamente superiores nos fatores “Problemas com as autoridades” (t (250) = -2,97; p = 0,004) e “Más condições físicas de trabalho” (t (250) = -3,94; p < 0,001), mas as que trabalham na praça pontuam mais fortemente no fator Insegurança (t (250) = 4,23, p < 0,001). Os resultados das análises de regressão múltipla mostram que os fatores “F3” (Beta = -0,231; p<0,001) e “F4” (Beta = -0,126; p<0,001) impactam significativamente no indicador de saúde física das zungueiras (R2ajustado = 0,08, p<0,001; F (4, 247) = 4,081; p<0,001). Por conseguinte, concluímos que na zunga existem fatores de elevado stress e que isso condiciona a sua saúde física.
Cheers,
