Online gambling, unlike other offline addiction forms, provides unprecedented opportunities for monitoring users’ behaviour in real-time, along with the ability to adapt persuasive interactions and messages that would match ...

Biomedical research and clinical decision depend increasingly on scientific evidence realized by a number of au-thoritative databases, mostly public and continually enriched via peer scientific contributions. Given the ...

Purpose – In order to enhance privacy protection during electronic transactions, the purpose of this paper is to propose, develop, and evaluate a personal data management framework called Polis that abides by the following ...

The purpose of this study was to examine the variables of ethnic identity, collective self-esteem, person perception, individualism, collectivism, and prejudice in Caucasian (North and South), African-American, and ...

The current study aimed to identify potential psychosocial risk and protective factors contributing to eating disorders in adolescents, and observe any differences between genders and Body Mass Index (BMI) categories. A ...

Dear Reader, Both body image as a construct and eating disorders as diagnoses are complex and multidimensional. Therefore, their continuous research and in-depth assessment is a necessity in order to better understand ...
