در این پایان نامه توزیع آماره های ترتیبی از توزیع نرمال دو متغیره و سه متغیره محاسبه می کنیم. همچنین به معرفی توزیع چوله نرمال یکریخت که با نماد sun نمایش می دهیم تابع مولد گشتاور این توزیع و برخی از خواص آن می پردازیم. نحوه ساختن توزیع sun را از توزیع نرمال سه متغیره ارائه می دهیم و نشان می دهیم که توزیع آماره های ترتیبی از توزیع نرمال سه متغیره به صورت مخلوطی از توزیع sun می شود.
OBJECTIVES The present research examined the sun protection intentions and behaviours of young people in a high risk skin cancer area using an extended theory of planned behaviour (TPB) incorporating additional social influences of group and image norms.

The intervention included staff training; sun-safety lessons; interactive activities; providing sunscreen, shade, and signage; and promoting sun-safe environments. A randomized trial at 28 swimming pools in...

In a paper published in the June 1999 issue of Molecular Cell, the researchers demonstrated that the interaction between a protein called Rad23 and a protein complex kn...
OBJECTIVE Despite long-standing social psychological research supporting the influence of injunctive norms (i.e., what is commonly approved or disapproved) on behavior, support for this influence on health behaviors is limited.
