This paper primarily aims to introduce a model to enhance the performance of the stock market portfolio of the Iran Social Security Organization. Performance indices were measured using documentary-based research and expert interviews based on theoretical saturation to evaluate the stock portfolio performance of the Iran Social Security Organization relative to companies listed on the Tehran Stock Exchange (T.S.E.) during 2016-2020. The Delphi technique was employed to ensure the validity of the indices. Drawing on the analytical hierarchy process (A.H.P.), the indices were prioritized and ranked based on the weight vector. The Iran Social Security Organization was found to have poor stock portfolio performance based on risk, return, liquidity, Sharpe ratio, and T.O.P.S.I.S. Hence, several solutions were identified based on expert interviews through thematic analysis to improve the stock portfolio performance of the Iran Social Security Organization. The solutions were validated through the Delphi technique, prioritizing and quantifying the performance improvement indices using the A.H.P. Based on expert views and T.O.P.S.I.S., a stock portfolio performance improvement model was proposed for the Iran Social Security Organization. Handling the non-profitable, low-return, and out-of-strategy companies is the optimal solution for the portfolio performance improvement of the I.S.S.O., with portfolio modification based on liquidity, effective stock market-making, return-based stock risk management, synergy between the portfolio and value chain completion, and value-added creation approach to stock management and exchange having the second-fifth ranks, respectively.

Performance management is a systematic approach that helps to improve the organization's performance through the processes of setting strategic goals, measuring, collecting, and analyzing data, reviewing performance data reports, and applying its results. An evaluation and monitoring system in the form of performance management At the macro level, which monitors the upstream documents, development plans, etc. in the form of one-year or even fewer time schedules, and provides the necessary feedback to pave the way to achieve the vision at different structural and management levels, one of the necessities which is currently the main question of the research entitled "Which is the appropriate model for managing the performance of managers?". To achieve this goal, the factors were identified using a qualitative and quantitative combined approach. In the qualitative phase of the Systematic literature method (SLR) and Delphi technique. The articles and documents selected in the systematic literature method (SLR) were evaluated in terms of quality through the CASP method. Based on the findings, 6 factors were identified as effective factors on performance. Managers were identified as external organizational factors - internal organizational factors - individual factors - input elements - performance management processes - results. Each of these factors has been used separately or in combination in various articles and research.

This article is structured in two parts. In the first part there is a focus on Deleuze’s philosophy and in particular the question of desert(ed) islands. Running throughout this section is a consistent concern with empathy and sociality, with the changing structure of alterity in the identified movement from neurosis, psychosis to perversion. In this section I make the argument that several forms of contemporary philosophy are carrying out acts of philosophical autism with regards to species extinction and the question of the absence of the other. I try to counter this trend in the second part of the paper where there is a concern with thinking the structure “Us-without-world,” which is my original contribution. In the time of the coronavirus pandemic, in the time of our forced solitude, in the time of our intoxication with technology, there is a real problem of the life-world, of thinking we-experience in common life, in this new hermetic reality. This is encapsulated in the thought-experiment of the structure “Us-without-world”.
