We analyzed the effect of time and frequency domain windowing, or weighting, of the transmitted signal for least squares (LS) and minimum mean-square error (MMSE) estimators when the channel is time-variant. We considered the estimation error for different windows and we found that the windows can be selected independently. We explained the performance of the estimators with the help of the rad...

Analyzing political conservatism as motivated social cognition integrates theories of personality (authoritarianism, dogmatism-intolerance of ambiguity), epistemic and existential needs (for closure, regulatory focus, terror management), and ideological rationalization (social dominance, system justification). A meta-analysis (88 samples, 12 countries, 22,818 cases) confirms that several psycho...

So far the least growth rate known for a divergent inherent ambiguity function was logarithmic. This paper shows that for each computable divergent total non-decreasing function f : N → N there is a context-free language L with a divergent inherent ambiguity function g below f . This proves that extremely slow growing divergent inherent ambiguity functions exist. For instance there is a context...

Microaggressions are unintentional or thoughtless behaviors that convey negative messages to members of minority groups. Due to the attributional ambiguity of microaggressions, people often differ in their judgments about how morally bad acts of microaggression are. To account for this individual variation, we explored the potential influence of heavy social media use on individuals’ moral judg...
