The aim of this study was to design and validate the competency model of the Senior managers of financial managers in the National Iranian Oil Company with a mixed approach. In the qualitative part, the researcher collected information using semi-structured in-depth field and purposeful interviews with 8 Senior Managers and Deputies of the National Oil Company, using a researcher-made questionnaire from the Managers and experts of the National Oil Company. And using the method of theme analysis and With Broun and Clarke approach, has analyzed qualitative data and in the quantitative part through Structural equation method. Based on the research findings, the competency model of the senior managers of the refinery was studied with 4 comprehensive themes and 26 main themes that comprehensive themes include technical skills, leadership skills, individual skills and business skills.

In this study, a model for the competence of financial managers in the National Iranian Oil Company was designed. Therefore, this study is applied in terms of purpose, qualitative in terms of approach and exploratory and descriptive-survey in terms of method. Data analysis was performed in two parts. In the first part, the pattern dimensions were identified using the theme analysis method, then in the second part, the Delphi method was used to confirm the proposed model. Therefore, in the present study, two groups of society were studied. 1. The statistical population of the theme analysis method, which included senior managers, deputies, heads and financial experts in the National Oil Company. The sampling method in this section was purposeful and performed by snowball method. 2. The statistical population of the Delphi method included 20 experts, heads and specialists in the field of financial management of the oil company. The sampling method in this section was based on the selection of individuals based on expertise and experience. The information of the first part was collected through interviews and the second part was collected through a questionnaire. Based on the research findings, 26 components were identified and approved in the form of 4 dimensions for the competence of the financial managers of the oil company. The four dimensions include technical skills, leadership skills, individual skills, and business skills. It seems that the model and the results of the research can be effective in the proper selection of financial managers and their growth and development.

The water table in the Zanjanrood catchment has severely declined recently. Therefore, determination of the groundwater potential zoning map is of great importance for optimal management of water resources. Here, we used seven effective criteria including lithology, slope, drainage, lineament, rainfall, spring density and landuse to asses groundwater potential. The analytical hierarchical analysis process was used for weighting the criteria. Overlay analysis was implemented using TOPSIS model to prepare the groundwater potential map in four categories of priority including very-good, good, low and poor. In general, the very-good category corresponds with the first priority while the lowest potential of groundwater match with the fourth priority. The high-discharged production wells and the geoelectrical investigations (resistivity and induced polarization) were applied to verify the model. The spatial distribution of the high-discharge production wells has completely coincided with both the very-good and good priorities in the area. The results of resistivity and IP models also are in good agreement with those from the TOPSIS model. Overall, the results suggest there is no rich aquifer in mountains of the Zanjanrood catchment. Furthermore, the most important aquifer in the Zanjanrood catchment is located around the Zanjanrood River where a severe water table decline has occurred.

Proliferation and virulence of entomopathogenic fungi can be affected by exposure to pesticides. Compatibility of Metarhizium anisopliae (Metschnikoff) Sorokin (DEMI 001 strain) with imidacloprid (IMI) was assayed by evaluating IMI effects on conidial germination، mycelial growth and sporulation. SDAY fungal cultivation medium was amended with IMI at concentrations of 10، 100 and 500 ppm. SDAY medium without insecticide was used as control treatment. The medium was inoculated by conidial suspension and the number of germinated conidia was counted after 24 h. Mycelial growth and sporulation were also measured. Results showed that IMI had no negative effect on conidial germination or mycelial growth. However، sporulation was progressively reduced as IMI concentrations increased. At the highest concentration of IMI، sporulation was reduced to 2. 40×107 conidia ml-1، compared with control at 4. 93×107 conidia ml-1. According to these results، IMI is reasonably compatible with strain DEMI 001. Additionally، mortality of M. diversus caused by either M. anisopliae or IMI alone، and in combination with different sublethal concentrations of IMI، was evaluated in laboratory bioassays. Mortality in combined treatments was significantly higher compared with non-combination treatments، indicating possible synergistic effects.
