Assessing Online Flow Across Cultures: A Two-Fold Measurement Invariance Study.

The association between online Flow and Internet Gaming Disorder (IGD) has attracted significant attention. Despite the consensus that online Flow plays a pivotal role in the development of IGD and other Internet addictive behaviors, there has been a lack of consistency in measurement scales used to assess online Flow. Even widely used measures of online Flow have not been psychometrically assessed across culturally diverse populations of gamers.

Cytologically interesting cases of primary skin tumors and tumor-like conditions identified by fine-needle aspiration biopsy.

The aims of this study are to depict the special but constant cytomorphologic features which allow a distinction among grossly similar skin tumors and to show that cytological assessment of many uncommon skin lesions is possible. The fine-needle aspiration findings of 181 cytologically interesting cases of primary skin tumors selected from 2,301 primary skin lesions examined in our department from 1990-1995 are described. Seventy-five cases were cytologically reported as benign and 89 as malignant.
