Introduction: The purpose of this research is to design and explain the model of professional ethics relations and the level of implementation of the policies of the Natural Resources and Watershed Management Organization of the country (a case study of the General Directorate of Natural Resources and Watershed Management in the North of Kerman Province). Material and Methods: In terms of the purpose of this research, it was developmental and applied, which was done in a mixed way. In the qualitative part of the society, there were university professors and experts in the field of human resources management, from among whom 30 people were selected by a judgment method. The tool was exploratory interviews and finally the data was analyzed with Delphi technique. In the quantitative part, the descriptive method was of the correlation type. The statistical population included all the managers and employees of the General Directorate of Natural Resources and Watershed Management of Kerman province and the sub-departments of the cities. The sample consisted of 358 people who were selected based on the available sampling method. A questionnaire was used to collect the required data. Data analysis was done using descriptive statistics and inferential statistics (one-sample t-test and structural equation modeling) using SPSS23 and AMOS23 software. Results: In the qualitative section, 70 sub-dimensions (indices) related to professional ethics were summarized in 5 factors and 79 sub-dimensions (indices) related to the implementation of the organization's policies were summarized in 4 factors. The analysis of the data in the quantitative part showed that there is a positive and significant relationship between the variable of professional ethics and the level of implementation of the organization's policies. Extra-organizational and individual (extra-personal) on the implementation of the organization's policies is significant at the 5% level, and the positive path coefficients show that these structures have had an increasing (direct) effect on the implementation of the organization's policies. Conclusion: Based on the present research, it was found that professional ethics has a significant effect on the level of implementation of the organization's policies.

The global demand for food can be eliminated by precision farming. This research work proposes a low-cost IoT-enabled handy device to measure soil water content. Three different sensor probes are designed in COMSOL Multiphysics 5.4 and fabricated using PCB Technology. The designed sensor probes are calibrated to effectively measure moisture content for three different soil types (silt/sandy/clay). An electronic system has been programmed according to Optimized-Moisture-Value (OMV) algorithm to read and collect the soil moisture information. Three sensor probes, capacitance, and voltage responses are analyzed using linear fitting. It has been observed from the response data that model B's performance is better than the other two presented models in terms of soil moisture. The obtained goodness of fitness value for model B is around 0.999 for all the categories of soils. The electronic system is built around W78E054D and ESP8266 controllers. The W78E054D controller is used to excite the sensor probe with a signal having a frequency of 500 kHz. The IoT-enabled controller ESP8266 reads and collects the soil moisture data according to the OMV algorithm.

Retailers need to take care of their customers and attract new customers through introducing and advertising their products, considering that social network marketing communication has created a new and profound transformation in businesses. Retailers need to exploit and be more effective. Making their connections in the created space. Therefore, in this research, we present a model for the effectiveness of marketing communication in social networks for the first time in the retail industry in Iran. The statistical population of the research was determined by using targeted sampling among experts, including academic professors and marketing managers of retail companies, and using coding in the software, four main themes were extracted from interviews with the statistical population and related to the subject of research and information. Among the researcher's notes, the codes (concepts) of branding, brand preference, sales increase, word of mouth, and commercial advertising have been the most frequent. This model can be used by retail owners and business managers to create a sustainable competitive advantage through social networks, increasing the effectiveness of market communication.

Greenwashing is considered as a deliberate and conscious deception of the consumer in relation to the environmental activities of an organization or the environmental benefits of a product, which has adverse consequences for various groups, including consumers, stakeholders and the environment, therefore, the purpose of this article was to analyze the different angles of greenwashing in the real context of the companies active in the dairy industry, as well as to identify and explain this phenomenon. The philosophy of this research is interpretive, its approach is qualitative, and the strategy used is grounded theory based on the emergent approach. The studied community included managers and activists of the dairy industry and related organizations, 15of whom were selected through purposive sampling until reaching theoretical saturation, and the research data was collected through semi-structured interviews. In order to check the strength of the research, the four criteria of reliability, transferability, reliability and verifiability have been used. The relevant data analysis has been done using MAXQDA software and open, central and selective coding processes, and during continuous comparison, 427codes, 27concepts, 11categories and 2categories have been obtained. which has led to the emergence of the final model of research around the central category under the title of "companies greenwashing actions" model. The mentioned model includes the causes and results related to the central category of the research. In general, this study, by explaining the greenwashing measures theory, has provided the necessary platform for understanding this category of measures as well as their control and prevention.

Home businesses play a positive role in economic growth and development. Therefore, the development of the capabilities of these businesses is an important issue in economic success. The purpose of this research was to investigate the impact of entrepreneurial knowledge on the structure and performance of home businesses. In this research, the indirect effect of the structure of home businesses on the performance of these types of businesses has been investigated. The data used in the analysis of this study were collected from 139home business owners using a questionnaire. Data analysis was done using structural equation modeling method with PLS approach and questionnaire constructs show good validity and reliability. Previous knowledge of home business owners has a positive (β=0.392) and significant (T=2.289, >1.96) effect on business structure performance. Therefore, the first research hypothesis is supported. Previous knowledge of home business owners has a positive (β=0.597) and significant (T=6.310, >1.96) effect on the performance structure of home businesses. And therefore, the second hypothesis of the research is supported. The structure of home businesses has a positive (β=0.4) and significant (T=2.124, >1.96) effect on business performance. And therefore, the third hypothesis of the research is also supported.
