This study attempted to devise and evaluate four belief systems regarding how people acquire their money and spend their time: the Protestant Work Ethic (P WE) which emphasizes the positive feature of work, the leisure ethic which sees recreation rather than work as the main means to personalfulfillment, the wealth ethic which stresses the accumulation of wealth to ensure independence from others and work, and the welfare ethic which is based on the idea that one should exploit state benefits as a primary source of income. As predicted, the PWE was significantly negatively correlated with the leisure and welfare ethic which were themselves positively correlated. The wealth ethic was significantly correlated with the leisure ethic. Correlations between subscale scores derived from factor analysis and other related measures showed an interesting and predicted pattern of work-related beliefs. Results are discussed in terms of developing and testing belief systems associated with the PWE.
Recebido em 13/9/09; aceito em 21/1/10; publicado na web em 3/5/10Blainvillea rhomboidea: CHEMICAL CONSTITUENTS AND CYTOTOXIC ACTIVITY. The phytochemical investigation of the ethanol extract from the aerial parts of Blainvillea rhomboidea (Asteraceae) resulted in the isolation and characterization of 8β-tigloyloxy-grazielia acid, together with the flavonoids derrone, acacetin, luteolin and luteolin 7-methyl ether, and p-(1-methylethan-1-ol)-phenol. The structures of all compounds were determined by spectroscopic methods ( 1 H and 13 C NMR and HREIMS) and comparison with published spectral data. The flavonoids luteolin and 7-O-metyl-luteolin, isolated from the active dichloromethane fraction, showed moderate cytotoxic activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
