    Group dynamics features are important factors for improving farmers’ socio-economic status. This study focused on the effect of group dynamics features on the socio-economic status of cocoa farmers in Ogun State, Nigeria. A multi-stage sampling technique was used to select 93 cocoa farmers for the study. Descriptive statistics and linear regression were used to analyze the data. Results showed that the mean monetary value of their material possessions, income generated from the cocoa producer per production cycle per year and other agricultural production activities were 9,819,796.60 Naira, 2,693,900 Naira and 1,887,400 Naira respectively. Majority (51.7%) of the cocoa farmers are of moderate socioeconomic status (M=4,800,365.53 Naira). Results showed that the group dynamics features of the cocoa farmers are high in group cohesion (M=31.04) and leadership dynamism (M=25.75) while it is low in group attitude and behavior (M=23.09), discipline, trust and accountability (M=17.76) and group rapport (M=14.47). The results of linear regression revealed that farming experience (β=0.301) and educational level (β=0.561) significantly (p< 0.01) increased the socio-economic status of the cocoa farmers. The study concluded that personal characteristics can influence cocoa farmers’ socio-economic status and their group dynamics features. The study recommended that cocoa farmers’ personal characteristics (educational level and farming experience) should be improved through intervention programs, training and sensitization as this will translate into better-quality group dynamics features thereby enhancing their socio-economic status.

    Rural areas have always played a significant role in the global economy by providing a variety of foods and raw materials. This role is much more prominent in developing countries. Rural development is also an important part of regional policies, covering agriculture, forestry, natural resource management, land use, and economic diversity in these areas. The present study focused on investigating rural development in rural areas of Islamshar County, Iran. Given the lack of productivity in this region and the fact that this county is so close to two metropolitan cities of Karaj and Tehran, it is necessary to examine the level of development of the villages in this county. Among various methods of ranking, the credit and point of rural development in this research were measured by AHP-based TOPSIS, factor analysis, and scale gram methods. Categorization by TOPSIS and factor analysis revealed close results considering 27 criteria for the evaluation of choices. Scale gram analysis generally confirmed these results. Also, the overall results show that the economic factor derived from the factor analysis method and the agricultural factor derived from the AHP method were acceptable. According to the viewpoint of the research population, many of the rural areas in the studied county were categorized in "deprived" group.

    The purpose of the present study was the simulation of climate change effects on groundwater resources in Iran by using the dynamic systems approach. The approach was performed through system dynamics modeling process including problem explanation, system description, model development, model testing, and the use of the model for policy analysis. The impact of the application of various exogenous scenarios including drought scenarios, management of water supply and population growth was assessed and the behavior of variables of water resources volume and per capita volume of renewable water of the Southern Khorasan province was simulated by Vensim software for the 2013-2041 period. Data were collected by referring to relevant organizations like South Khorasan Regional Water Organization, South Khorasan Agricultural Organization, and Statistical Center of Iran and the input data of the model were fed into the model in an Excel worksheet. The results showed that the water resource exploitation management scenario had a significant positive effect on the balance of aquifers of South Khorasan Province so that the balance of the province aquifers in the scenario of controlling water resources exploitation has been significantly different from the scenario of the lack of control of different drought in all the studied years. In addition, the results of examination of the province's renewable water showed that droughts have had a negative impact on the volume of renewable water of the province and droughts together with population growth have reduced the province per capita renewable water.

    The aim of this study was to determine the probability of working days (PWD) for tillage operation using weather data with Multiple Linear Regression (MLR) and Radial Basis Function (RBF) artificial networks. In both models, seven variables were considered as input parameters, namely minimum, average and maximum temperature, relative humidity, rainfall, wind speed, and evaporation on a daily basis. The PWD was considered to be the output of the developed models. Performance criteria were RMSE, MAPE, and R2. Results showed that the R2-valuewas 0.78 and 0.99 for MLR and RBF models, respectively. Both models had acceptable performance, but the RBF model was more accurate than the MLR model. The RMSE and MAPE values for the RBF model were lower than those for the MLR model. Thus, the RBF model was selected as the suitable model for predicting PWD. Moreover, the results of these models were compared to the prior soil moisture model. It was indicated that the results of the studied models had a good agreement with the results of the soil moisture model. However, the RBF model had the highest R2 (99%). In conclusion, the developed RBF model could be used to predict the probability of working days in terms of agricultural management policies.

    Economic theories show that the direction and magnitude of the fluctuations of economic variables depend on the type and magnitude of the shocks they are faced with. Various reasons are noted for fluctuations in demands for imports, including productivity shocks. Accordingly, this research was aimed at identifying the effects of Total Factor Productivity (TFP) shocks of the agricultural sector on the demand for agricultural imports during the period 1982-2014. These shocks were divided by the Blanchard-Quah technique into two groups: permanent and temporary. Then, the effects of shocks on agricultural imports were studied by the Structural Vector Auto Regression (SVAR) Method. The results showed that, in the short and longrun, temporary and permanent TFP shocks of the agricultural sector have had a significant effect on the demand for agricultural imports, and the effect of temporary shocks was stronger than the effect of permanent ones. Therefore, if the policymakers seek to reduce the demand for agricultural imports, the agricultural TFP must continuously be incremented.

    The main objective of this research was to investigate the effect of managerial power on entrepreneurship psychological characteristics of employees in Agriculture Jahad Organizationsof Western Azarbaijan Province. The stratified random sampling method was applied for data collection. In order to collect data, the power assessment questionnaire developed by Hinkin and Schriesheim (1989) and that of assessing entrepreneurship psychological characteristics developed by Durham Institute were used. Structural Equation Modeling (SEM) based on partial least squares approach and SmartPLS v2 were used to analyze data. Results showed a significant positive relationship between managerial power (except for coercive power) and achievement orientation, intrinsic control, creativity, ambiguity tolerance, and independence characteristics; however, no significant relationship was observed between managerial power and the risk-taking characteristic. Additionally, results from the structural model showed managers' referent and expert powers have a significant positive effect on entrepreneurship psychological characteristics of employees. Therefore, drawing on the results of this research and the proper use of their power, managers of Agriculture Jahad Organizationscan develop and strengthen entrepreneurial characteristics and entrepreneurship spirit amongst their employees, and consequently, guarantee the organization success and prosperity.
