Electronic-commerce has become an important channel for conducting business. Researchers as well as market executives are trying to better understand online consumer behavior. One model used by researchers to understand behavior in the information systems field in general is the technology acceptance model (TAM). The TAM variables are perceived usefulness, perceived ease of use, and intentions. In this study, we suggest the extension of the TAM for its application in the E-commerce field. The original TAM will be extended, by adding four predictor variables. The four predictor variables are process satisfaction, outcome satisfaction, expectations, and E-commerce use. In addition, the TAM will be extended by measuring actual behavior as opposed to measuring intentions as a substitute for actual behavior in previous TAM application studies. We suggest measuring actual use variable in terms of four criterion variables, namely, purchase, access number, access total time, and access average time. The extended TAM is expected to better explain actual behavior in E-commerce environments than the original TAM. [ABSTRACT FROM AUTHOR]

Antiangiogenic compounds are gaining more and more interest as a new approach in the prevention and treatment of cancer and inflammatory diseases. The objective of this study was the evaluation of the antiangiogenic effect of a red clover extract (RCE) used in food supplements for menopausal complaints as well as of its main isoflavones in an in vivo system, the chorioallantoic membrane assay of fertilized hen's eggs. At a dosage of 250 microg/pellet the red clover extract showed excellent inhibition of angiogenesis. The antiangiogenic activity of the non-methylated isoflavones daidzein and genistein was higher than that of the methylated compounds formononentin and biochanin A. The results demonstrate that RCE is not only suitable for menopausal complaints, but might also be a powerful chemopreventive agent against chronic diseases e.g. which have a high incidence especially in elderly female.

Abstract: Introduction: The purpose of this study was to examine attitudes and behaviors associated with parenthood and pregnancy among adolescents in the juvenile justice system. Method: A cross-sectional survey of attitudes and behaviors about parenthood was conducted with 300 adolescents residing in three juvenile detention centers. Results: Data revealed high rates of risky behaviors that resulted in parenthood/pregnancy and generally positive attitudes about being an adolescent parent. Positive attitudes about parenthood (P = .000) and lower self-efficacy to not have sex (P = .021) were significantly correlated with having been pregnant or having fathered a child. Logistic regression showed positive attitudes about parenthood and the combination of drinking and driving together were significant predictors of pregnancy (P ≤ .05). Discussion: Pediatric nurse practitioners working with adolescents in the juvenile justice system who routinely provide prevention counseling and implement health promotion programs must take into account the reality that many adolescents in this population are or will become parents and do not consider pregnancy as an outcome to be necessarily avoided. Moving beyond primary and secondary prevention strategies to implement programs to prevent second pregnancies and enhance parenting skills will provide needed health benefits to these adolescent parents.
