Today, thinkers and policymakers envision new roles for human resource management, one of the most important one is "competency-basing" in all functions of human resource management from planning and selection as input processes to the development and maintenance and output processes of human resources. The purpose of this article is to review the “, Competency-Based human resource management”,book by David Dubios et al. The book is reviewed and criticized based on two methods of formalist critique that focuses on form-elements such as structure and writing-and research critique that gives originality to the content, and also based on the criteria of the Iranian Council for Reviewing Books and Text on human Sciences. Findings showed that the main strengths of the book are having a theoretical and practical perspective, paying attention to the organizational context in the application of competencies and confronting and comparing traditional with competency-based human resource processes. This work also has points for improvement, the most important of which are the lack of up-to-date references despite the reprint of the book, issues unrelated to or less related to the main concept of the book, and the need to explain new methods of human resource management processes in the competency-based approach. In the end, based on the findings, suggestions were made in two headings of form and content.

human resource slack is one of the terms that has recently entered the human resources management literature. human resources slack refer to more resources than the organization needs. This study aims to identify the types of stagnant human resources and provide a model of human resource management functions appropriate for each type of stagnant employees. The present research is qualitative and fundamental in terms of systematic method and content analysis. For this purpose, systematic search was limited to two databases, including Scopus (Elsevier) and the Scientific Network Information Science Institute (Thomson Reuters), to identify and extract articles. After reviewing the articles, the model was presented. The CASP standard checklist was used to assess the validity of the research and in order to assess the reliability of the research, the Kappa Cohen index in SPSS software was used, which was approved. After presenting the model, using semi-structured interviews with academic and industrial experts and conducting content analysis of human resource management functions such as training, development, rewarding and Service compensation, and performance control and evaluation, for each type of employee slack. The model presented, citing articles, introduces four types of human resources slack by considering two dimensions of strategic value and competence,Surplus-oriented, Accumulated-oriented, Knowledge-oriented and Value-oriented. The proposed model and the proposed functions for each type of employee slack can be the basis for future researchers' research.

Green human resource management is the most important component of green management which has attracted the attention of many HRM researchers recently. This research is aimed at designing a structural model of human resource management based on human resource management systems. It is being proposed for the first time in the literature of human resource management. This applied research follows a descriptive-survey method. It is a cross-sectional research in terms of time. A combination of a structured questionnaire on green human resources management and a researcher-made questionnaire on human resource management systems was used for data collection. The reliability of the instruments was tested through convergent method, and the validity was calculated by Cronbach's alpha coefficient. The statistical population of this research contains all managers of Fars Power Distribution Company (120 members). The sample included 92 people selected according to Cochran formula based on stratified random sampling. The research hypotheses were tested through structural equation modeling with SmartPLS software. The results indicated that the effectiveness of predictive variables for implementing green human resources management can be ranked in the following way: maintenance, compensation, performance management and human resource development. The relationship between these systems and the management of green human resources turned out to be significant.

The ultimate goal of this research is to conceptualize a new face of human resource management, called diplomatic human resource management, which seems to be more suitable with the characteristics of the current environment of organizations. Issues such as the diversity of the workforce, conflicts between individuals and groups, conflict over interests, different generational values of the workforce, the presence of unruly people in organizations, and things like that, along with the fact that the environment of organizations is more of a political environment than a rational environment. And it is full of political behaviors, it has doubled the need to conceptualize human resources management as a kind of special diplomatic work. The current research is qualitative in terms of approach and basic research in terms of purpose. The participants of this research are 25 managers and human resources specialists who had some kind of lived experience around the research problem. These people were selected by purposeful sampling and semi-structured interviews conducted with them were coded by thematic analysis method. The findings indicate that "influence between employees by establishing positive relationships" and "monitoring employees while maintaining their human dignity" are at the heart and essence of the concept of diplomatic human resource management and strategies for injecting diplomacy in all dimensions and specialties of human resource management. Diplomatic human resource management is an approach of managing the organization's employees, which assumes that organizations are socio-political systems and mixed with different stakeholders,

The purpose of this research is to provide a model of digital human resources management with a data-based approach. The current research is applicable-developmental in terms of purpose, descriptive in terms of information gathering, and qualitative in terms of the nature of the data. The statistical population of the research includes specialists and experts familiar with digital human resource management topics. Sampling in this research was snowball type. Based on the subject of the desired data,through preliminary studies, semi-structured interviews, collection, and sampling continued until reaching theoretical saturation. The obtained information was analyzed with MAXQDA2020 software. The results showed that the digital human resources management model with the data-based approach includes causal factors (technological, environmental, human, and organizational), background factors (digital platform, management platform, and individual platform), intervening factors (cultural factors and creation of platforms new), strategies (organizational and managerial), and consequences (individual, cultural, and organizational), which is necessary, according to the mentioned model, while paying attention to the multiplicity, to provide the ground for the implementation of the desired situation.
