Abstract

This study examined the psychometric properties of a newly developed scale to assess motivations for fostering. A total of 447 Portuguese adults completed online the MIAF – Motivations for Fostering Scale (MIAF-MFS; ProChild CoLAB & SCML, 2024) and reported on sociodemographic data, perceived knowledge about family foster care, and intention of becoming a foster family. The exploratory and confirmatory factor analyses revealed a 4-structure factor. Convergent validity was shown by significant associations between the MIAF-MFS factors and perceived knowledge about family foster care and intention of becoming a foster family. The MIAF-MFS factors presented are acceptable to high reliability. [ABSTRACT FROM AUTHOR]

Abstract

Camellia sinensis tea has received considerable attention due to its beneficial effects on health, particularly due to its antioxidant properties that are affected by several factors, which have a high influence on the final quality of black tea. The objective of this study was to investigate the biological properties of Azorean C. sinensis black tea from five different zones of tea plantation in order to select specific areas to cultivate tea rich in targeted compounds beneficial to human health. The free radical scavenging activity (FRSA), ferric reducing antioxidant power (FRAP), ferrous ion chelating (FIC) activities, total phenolic content (TPC), total flavonoid content (TFC), and tannins were determined by colorimetric methods, and catechin and theaflavin contents were analyzed by high-pressure liquid chromatography. The results indicated that samples from Zone E (341 m above the sea level) presented higher values of FRSA (EC50 = 7.22 µg/mL), FRAP (EC50 = 9.06 µg/mL), and FIC activities (79.83%) and higher values of total phenolics (264.76 mg GAE/g DE) and almost all catechins. For TFC, the values were very similar between zones, and for theaflavins content, Zone A showed the best levels, followed by Zone E. In general, these results clearly highlight that altitude plays a significant role in enhancing certain compounds of tea, thereby influencing its quality.
