Handwashing adherence during the COVID-19 pandemic: a longitudinal study based ...
Szczuka, Zofia; Siwa, Maria; Abraham, Charles; Baban, Adriana; Brooks, Sydney; Cipolletta, Sabrina; Danso, Ebrima; Dombrowski, Stephan U.; Gan, YiqunRationale: The associations between the number of COVID-19 cases/deaths and subsequent uptake of protective behaviors may reflect cognitive and behavioral responses to threat-relevant information. Objective: Applying protection motivation theory (PMT), this study explored whether the number of total COVID-19 cases/deaths and general anxiety were associated with cross-situational handwashing adherence and whethe...
The interplay between strictness of policies and individuals’ self-regulatory e...
Luszczynska, Aleksandra; Szczuka, Zofia; Abraham, Charles; Baban, Adriana; Brooks, Sydney; Cipolletta, Sabrina; Danso, Ebrima; Dombrowski, Stephan U.Background: Patterns of protective health behaviors, such as handwashing and sanitizing during the COVID-19 pandemic, may be predicted by macro-level variables, such as regulations specified by public health policies. Health behavior patterns may also be predicted by micro-level variables, such as self-regulatory cognitions specified by health behavior models, including the Health Action Process Approach (HAPA)...
The trajectory of COVID-19 pandemic and handwashing adherence: findings from 14...
Szczuka, Zofia; Abraham, Charles; Baban, Adriana; Brooks, Sydney; Cipolletta, Sabrina; Danso, Ebrima; Dombrowski, Stephan U.; Gan, Yiqun; Gaspar, TaniaBackground: The COVID-19 pandemic has affected people's engagement in health behaviors, especially those that protect individuals from SARS-CoV-2 transmission, such as handwashing/sanitizing. This study investigated whether adherence to the World Health Organization's (WHO) handwashing guidelines (the outcome variable) was associated with the trajectory of the COVID-19 pandemic, as measured by the following 6 i...
Cd and Cu interdiffusion in Cu(In,Ga)Se2/CdS hetero-interfaces
Salomé, Pedro M. P.; Ribeiro-Andrade, Rodrigo; Teixeira, Jennifer P.; Keller, Jan; Törndahl, Tobias; Nicoara, Nicoleta; Edoff, MarikaWe report a detailed characterization of an industry-like prepared Cu(In,Ga)Se2 (CIGS)/CdS heterojunction by scanning transmission electron microscopy (STEM) and photoluminescence (PL). Energy dispersive x-ray spectroscopy (EDS) shows the presence of several regions in the CIGS layer that are Cu deprived and Cd enriched, suggesting the segregation of Cd-Se. Concurrently, the CdS layer shows Cd-deprived regions ...
Influence of CdS and ZnSnO buffer layers on the photoluminescence of Cu(In,Ga)S...
Salomé, Pedro M. P.; Teixeira, Jennifer P.; Keller, Jan; Törndahl, Tobias; Sadewasser, Sascha; Leitão, Joaquim P.The search for alternatives to the CdS buffer layer in Cu(In,Ga)Se 2 (CIGS) solar cells has turned out to be quite promising in terms of power conversion efficiency. In this paper, the typically used chemical-bath-deposited CdS layer is compared with an atomic-layer-deposited Zn 1-x Sn x O y (ZnSnO). An optical study by external quantum efficiency and photoluminescence on the influence of different buffer layer...
