Objective: Based on Elliot’s revised achievement goal framework [Elliot and McGregor (2001). A 2 2 achievement goal framework. Journal of Personality and Social Psychology, 80, 501–519], the present study tested the gender invariance of the multiple achievement goal measurement model as well as the hypothesized antecedents and consequences of the multiple achievement goals embedded in a structu...

Two studies investigated the validity of computer self-efficacy and computer anxiety scales when administered to an Internet sample. In the first study, it was found that existing measures of computer self-efficacy and anxiety, originally developed through paper-and-pencil methods with more traditional samples, were not adequately equivalent when administered to a sample that was recruited and ...

Web surveys have become a very important way of empirical research. The rise of social media provides a new platform for web surveys. Investigators can collect data based on different social media platforms to get more respondents of higher external validity at a lower cost. However, there is no domestic expert and scholar to conduct related researches on web surveys based on social media. This...

We examined the development of self-esteem across the lifespan. Data came from a German longitudinal study with three assessments across 4 years of a sample of 2,509 individuals aged 14 to 89 years. The self-esteem measure used showed strong measurement invariance across assessments and birth cohorts. Latent growth curve analyses indicated that self-esteem follows a quadratic trajectory across ...

In this paper, a new invariant called {it logic entropy} for dynamical systems on a D-poset is introduced. Also, the {it conditional logical entropy} is defined and then some of its properties are studied.  The invariance of the {it logic entropy} of a system  under isomorphism is proved. At the end,  the notion of an $ m $-generator of a dynamical system is introduced and a version of the Kolm...

     The quadratic loss function has been used by decision-theoretic statisticians and economists for many years.  In this paper  the estimation of scale parameter under a bounded loss function, which is adequate for assessing quality and quality improvement, is considered with restriction to the principles of invariance and risk unbiasedness. An implicit form of minimum risk scale equivariant ...
