The present research is inclined to study the relationship between two important forms of “Contract” in employment relations, psychological contract and knowledge contract, and job outcomes, i.e. employee retention and employee satisfaction. For this purpose, the data were collected from 268 employees working in the IT sector from North India. The results suggest the mediating impact of the psychological contract in the relationship between knowledge contract and job outcomes. Besides, this study develops a theoretical model that establishes the relationship between knowledge sharing and knowledge integration that plays a major role in employee satisfaction as well as retention of employees in the organization.

In the contemporary dynamic business context (characterized by stiff competition, high uncertainty, growth of global as well as virtual organizations, etc.), setting up systems for recognizing and engaging employees which need constant endeavor from present-day organizations. Hence, organizations are actively exploring and adopting novel initiatives through strategies platforms for their employer engaging effort, moving the organization image to the “company of employee’s choice” and connecting their strategic talent acquisition supply chain into that eco-system. Qualitative data analysis through 65 semi-structured interviews with employees working with various Software and Research & Development sectors, Human Resources and Talent Management professionals working for information technologies companies, IT-enabled (Business Process Outsourcing) BPO, and KPO (Knowledge Process Outsourcing) Services, as well as talent acquisition organizations, confirm the utilization of social media for social recognition & employee engagement in their organizations. The study contributes to the fields of talent management and social networks and has several key messages for practitioners regarding the expediency and effectiveness of social networks in organizations.

In the Internet of Medical Things (IoMT), medical devices are connected to the Internet of Things (IoT), allowing better tailored healthcare, faster hospital treatments, more affordable medical solutions, and more patient comfort. The most serious threat to the safety and confidentiality of patient’s medical records is the possibility of attacks on the IoMT environment. In order to address these problems, researchers have proposed several approaches and methodologies. None of these protocols presents a low-computing-overhead method that combines authentication with privacy preservation. This research proposes a protocol for secure authentication of IoMT devices while protecting user privacy. The proposed approach ensures the confidentiality of the IoMT devices connected to the patient’s body while communicating. In addition, the proposed protocol is validated using the widely recognized formal validation tool Automated Validation of Internet Security Protocols and Applications (AVISPA). The suggested protocol resolves existing protocols’ vulnerabilities and is resistant to many well-known security issues. Compared with existing protocols that use public cryptosystems, such ElGamal and RSA, the suggested protocol stands out due to its smaller key size and reduced computational overhead. A comparison with the well-known protocols revealed that the combined method for “lightweight authentication and privacy preservation” is computationally 5 to 6 times more efficient. However, this research has significant real-world implications from various social, economic, and business viewpoints, both locally and globally.
