Equivalent electron correlations in nonsequential double ionization of noble atoms

Electron correlation is encoded directly in the distribution of the energetic electrons produced in a recollision-impact double ionization process, and varies with the laser field and the target atoms. In order to get equivalent electron correlation effects, one should enlarge the laser intensity cubically and the laser frequency linearly in proportion to the second ionization potentials of the target atoms. The physical mechanism behind the transform is to keep the ponderomotive parameter unchanged when the laser frequency is enlarged.

Intensity of the Reverse Sexual Double Standards in Females and Males and Possible Factors

Despite past researches on the sexual double standards(SDS),recent research has found that another type of sexual double standard exists,which is the reverse sexual double standard(i.e.reverse SDS,which means that men are judged more harshly than women in comparative sexual behaviors).According to previous researchers,the reverse SDS may stem from women’s worry about being infected by transmitted sexual diseases,women’s preference for men’s virginity in sexual behaviors,and the shift in attitude towards men’s sexual behaviors.Also,women tend to judge men’s sexual behaviors based on men’s attractiveness(body appearance and financial status).The present study investigated people’s implicit endorsement of the reverse SDS among 200 adults in Shanghai(20 to 50 years old,110 women,90 men)using the Implicit Association Test(IAT)with a priming procedure to limit participants’awareness including different levels of men’s body appearance and financial status.Additionally,SDSS(sexual double standard scale)was used to measure the explicit endorsement for the reverse SDS.According to my results,adults in Shanghai endorsed both an implicit and explicit reverse SDS,but women tend to endorse it more strongly than men.Also,when men are more attractive,women will judge them less harshly.These results indicate that the reverse SDS also exists in men.Implications and limitations are indicated for future researchers to call for attention to the reverse SDS and gender equality.

A Decision Method Based on Competition Model

We propose a decision method -double scale method to derive the priority vector of finite alternatives with respect to a single criterion based on competition model. Compared with the attribute hierarchical model, the double scale method is reasonable and practical.
