In today's world, urban waste management is one of the most important tasks of urban management, which has many implementation problems and costs. Waste collection, disposal and recycling operations are very costly due to the high costs of investing in the creation of a fleet of waste trucks. Also, significant operating costs for workers, drivers, fuel and maintenance have turned municipal waste management into a costly operation. Considering the high costs of urban waste management, small improvements in urban waste management will lead to great savings in waste management costs. The Internet of Things (IoT) is one of the efficient and suitable tools to reduce the costs of collecting and managing urban waste. In this article, the indicators and infrastructural requirements of establishing a smart city have been stated. Then, the prerequisites for establishing the Internet of Things for urban waste management in the cases of separation, collection and recycling of urban waste have been introduced. After that, a 5-layer model of Internet of Things deployment has been proposed for urban waste management. At the end of the article, the obstacles to establishing the Internet of Things in cities are briefly discussed.

The purpose of this research is to examine the impact of green human resource management practices on environmental performance with the AMO approach in Kerman Coal Mines Company. Descriptive-correlational research method, which was conducted by survey method, and the structural equation modeling approach was used to test the hypotheses. The statistical population includes 600 managers and supervisors and members of labor councils and technical and support experts of the coal mining company. The sample size was determined by 234 individuals based on the table of Krejcie and Morgan. The tools used to collect data are two questionnaires.

The content and construct validity of two questionnaires have been confirmed as 0.87 and 0.84 respectively, as well as its reliability as 0.88 and 0.86. The analysis of the research data was done at the level of descriptive statistics using SPSS23 software and structural equation modeling method using AMOS23 software. The results of the research indicated that the effect of the green ability variable on environmental performance is not significant; however, the variables of green motivation and provision of green opportunities are positive and significant on environmental performance. Therefore, it is suggested that by using green human resources management, the necessary measures and mechanisms to improve the green capability in Kerman Coal Mines Company should be carried out.

The main goal of the research is to identify the antecedents and consequences of the green human resources strategic management system. In order to achieve the goal of the research, the grounded theory research method has been used to develop the adopted research model. The participants of the study included 14 academic experts from top-tier universities and managers of water and wastewater companies, who were selected based on the principle of theoretical adequacy, using the purposeful sampling method. A semi-structured interview has been used for data collection. The results of the present research led to the identification of 12 main categories and 41 subcategories using a grounded theory approach. In order to design a green recruitment model, personality factors, green process development, technological conditions, waste management system implementation, green organizational culture, green intellectual capital, green communication were introduced as consequences and green energy consumption management, green health and safety management, economic factors and green performance improvement were identified as consequences of strategic management system of green human resources.
