Strong Structural Controllability of Signed Networks

In this paper, we discuss the controllability of a family of linear time-invariant (LTI) networks defined on a signed graph. In this direction, we introduce the notion of positive and negative signed zero forcing sets for the controllability analysis of positive and negative eigenvalues of system matrices with the same sign pattern. A sufficient combinatorial condition that ensures the strong structural controllability of signed networks is then proposed. Moreover, an upper bound on the maximum multiplicity of positive and negative eigenvalues associated with a signed graph is provided

Investigating the Effect of Training Career Path Skills based on Super’s Career Development Theory on Academic Self-Concept of Students of Isfahan University

The present study aimed to investigate the effect of training career path skills based on Super’s Development Theory on students’ academic self-concept. The study is a quasi-experimental with pretest-posttest design with a control group. The statistical population of the study consisted of all students of University of Isfahan year 2018. Using available sampling method, 30 people were selected and randomly, 15 of them were placed in the test group and 15 in the control group. The data collection tool was Academic Self-Concept Scale (ASCS) (Reynolds et al, 1980). The career path skills were trained to the test group for ten 90-minute sessions in groups, and no training was provided to the test group. The data were analyzed using SPSS software at the level of descriptive statistics including mean and standard deviation and at the level of inferential statistics by covariance analysis method. The results showed that training career path skills based on Super’s Development Theory has a significant positive effect on students’ academic self-concept

This research aimed to identify and describe the relationship between information technology use and organizational success in Yazd executive systems. According to this method, it is a descriptive correlation which is the purpose of the application.
