A study on effects of organizational structure on performance of research organizations

Organizational structure plays an important role on survival of any business units and it is important to understand different factors influencing it. In this paper, we present an empirical study to learn the effects of three parameters including formality, concentration and complexity on organizational performance. The proposed study of this paper is implemented for one of research-based organization located in city of Qom, Iran. There were 120 employees working for this organization and the proposed study of this paper has selected a sample of 100 people, designed, and distributed a questionnaire among them. The proposed study uses two methods of regression analysis as well as structural equation modeling to study the impacts of three variables on organizational performance. The results show that there are some positive and meaningful relationship between formality and concentration from one side and organizational performance from the other side. In addition, there is a meaningful and negative relationship between complexity and organizational performance. The results of structural equation modeling are also consistent with the results of structural equation modeling

Effect of Sensory Integration Therapy on Gross and Fine Motor Skills of 5-7 Years old Children with Down Syndrome

Objective: Children with Down syndrome have sensory integration dysfunction, and a range of physical problems and difficulties that may affect their motor development. The aim of present study was to determine effectiveness of sensory integration therapy on gross and fine motor skills of 5-7 years old children with Down syndrome.  Materials & Methods: Sixty 5-7 years old children were diagnosed as having Down syndrome, were selected by randomized sampling and participated in this experimental study. Each participant was assessed by researcher, that the assessment used was Peabody Developmental Motor Scales. The children were randomly assigned to the intervention (sensory integration therapy) and control groups. Sensory integration therapy was given to intervention group. Data were analyzed by Leven test, Independent T test and covariance analysis. Results: There was significant difference between pretest and post test scores of intervention and control groups in gross motor development (P<0.000), but in fine motor development there was significant difference between pretest and post test scores only in intervention group (P<0.001) and in control group it wasn’t significant (P=0.013). Also there was significant difference between two groups in gross and fine motor development (P<0.001). Conclusion: The results showed the sensory integration therapy were effective in gross and fine motor of children with Down syndrome. It was concluded that sensory integration therapy should be applied for children with Down syndrome who have gross and fine motor difficulties
