The objective of this study was to investigate the additive effect of 1000, 2000, 4000 and 8000 IU/kg of vitamin D3 on the productive and egg quality characteristics in Japanese quail. 320 adult Japanese quail were used. Experiment was done in a randomized complete block design with 5 treatments, 4 replicates and 16 quails in each replicate (12 female and 4 male birds) for 42 days. After 2 weeks of treatments, the productive characteristics of birds were recorded weekly for 6 weeks. At the end of experiment, 5 eggs were selected randomly from each replication and egg quality traits were examined. Feed conversion ratio and also some egg quality parameters including eggshell weight, egg width and diameter of thin albumen were influenced by levels of vitamin D3 (p<0.05). Although the egg quality parameters had no significant difference with control, but the egg shell weight and egg width percent were increased with increase the levels of vitami D3 from 4000 (15.90 and 2.67, respectively) to 8000 (14.41 and 2.51, respectively) IU/kg (p<0.05). The feed conversion ratio in 4000 IU/kg of vitamin D3 (3.68) was significantly lower than the control (4.22) (p<0.05). The other egg quality characteristic as well as feed intake, percentage of egg production and egg weight were not affected by treatments (p<0.05). The results of this study show the improvement of feed conversion and eggshell weight and egg width in Japanese quail's, especially at the level of 4000 IU/kg of vitamin D.

The present study tries to identify antecedents of branded production, focusing on shoe, slipper and plastic manufacturing companies in Qom province. Under branded production, a company which its manufacturing capacity could not meet market demand, can supply part of its products through outsourcing or subcontracting. This study's methods are applied ones in terms of results, explorative in terms of purpose, and qualitative in terms of data. The population of the research was executives in shoe, slipper and plastic companies in Qom province and sampling continued till the theoretical saturation. So, 20 executives were selected by convenience judgmental sampling method.  Data was obtained through interviewing twenty senior executives as well as field observations and review of previous studies and available documents and news. The instrument for obtaining data was interview and literature review. In data analysis, we used theme analysis method to identify antecedents and Shannon entropy for factor ranking. Research findings are introduced in three categories: factors influencing renowned brands' sell; factors creating vacant capacity; and the cause of executives’ reluctance towards branded production policy.

Today shopping is increasingly seen as a recreational activity and a escaping way from everyday life and even for some buyers, buying may be something beyond entertainment and turns to addiction and extremism. Cultural materialism and also development of new marketing techniques have many implications for communities that one of them is the growing phenomenon of compulsive buying. The aim of this research is to provide a model of compulsive buying among women. Statistical population of the research consists of 41 female students of Kashan University using judgment sampling. Data were collected and analyzed using interview and grounded theory via N Vivo 10 software, respectively. This research is a fundamental research and in terms of purpose and classification is qualitative. The obtained results are classified into five categories including central, causal, field, intervening, and strategic and their consequences are presented a well. The results showed that these factors cause to increase stress level, creation of bad moods and feelings as well as the need and desire to buy, that in the absence of control leads to compulsive buying and have some consequences for the individual and those around her. Many of the variables found in this research have been introduced for the first time and the proposed model has more details than the previous models.
