Modeling the Kidney Market in Iran
, M.Sc. Thesis Sharif University of Technology ; Fatemi Ardestani, Farshad (Supervisor)
Abstract
The purpose of this study is to model people's behavior on both sides of the kidney market. The healthy person decides to donate a live kidney (for a certain amount) on the supply side. On the demand side, the patient chooses between the two existing kidney queues, the living kidney and the cadaveric kidney, based on the individual's income and belief from the waiting time in each of the two queues. The sick person faces two critical risks in life: risk of death and kidney failure. To model these two risks, it is assumed that each person has a level of health that consists of two deterministic and stochastic parts. In this way, with a deterministic rate, a person's health level will decrease...

An integrated model has been developed to evaluate the impact of climate change due to power plant emissions on the human health. This model includes the equations regarding the variations in carbon dioxide concentration in the atmosphere,...
Possible Impacts of Telework Initiated by COVID-19 Outbreak on Teleworkers’ Psychological Well-being: A Qualitative Study
, M.Sc. Thesis Sharif University of Technology ; Alavi, Babak (Supervisor)
Abstract
This research explores the impacts of the telework initiated by the outbreak of COVID-19, which is being called “emergent telework” in this research, on psychological well-being of teleworkers. As for the nature of emergent telework which is a new and unique phenomenon, a qualitative research is conducted. In order to do so, 15 in-depth interviews were held with employees from product teams of 11 organizations, and the interviews were analyzed using thematic analysis. General conditions of teleworking are identified in two categories named as “not working adjacent to coworkers” and “being away from the physical environment of the workplace”. Emergent telework, alongside the general...

Abstract
Urmia Lake, located in a closed basin in north-west Iran, is the largest lake (5000-6000 km2) in the Middle East. It is very saline with total dissolved salts reaching 200 g/l compared with a normal seawater salinity of about 35 g/l. The construction of a causeway, which was initiated in 1979 but then abandoned until the early 2000s, is near completion and will provide road access between the western and eastern provinces. The causeway has an opening 1.25 km long and divides Urmia Lake into a northern and southern basin and restricts water exchange. The flow and salinity regimes are affected by the presence of this new causeway, and there are concerns over the well being of the Artemia...

Abstract
This study aimed to identify the influence of workplace cyber ostracism on employee online work engagement and employee mental well-being with the mediating roles of remote work challenges such as loneliness, procrastination, work-home interference, and ineffective communication. As amidst lockdown due to COVID-19, the data was collected from 303 respondents through an online questionnaire that was distributed in virtual groups among friends, relatives, and other fellows who were working in the private sector organizations of Pakistan. The hypotheses were tested using the partial least square structural equation modeling PLS-SEM technique. The findings of this study showed that workplace...
Is negative attention better than no attention? The comparative effects of ostracism and harassment at work
, Article Organization Science ; Volume 26, Issue 3 , 2015 , Pages 774-793 ; 10477039 (ISSN) ; Robinson, S. L ; Berdahl, J. L ; Banki, S ; Sharif University of Technology

Abstract
Ostracism has been recognized as conceptually and empirically distinct from harassment. Drawing from theory and research that suggests that employees have a strong need to belong in their organizations, we examine the comparative frequency and impact of ostracism and harassment in organizations across three field studies. Study 1 finds that a wide range of employees perceive ostracism, compared with harassment, to be more socially acceptable, less psychologically harmful, and less likely to be prohibited in their organization. Study 2 surveyed employees from a variety of organizations to test our theory that ostracism is actually a more harmful workplace experience than harassment....
The impact of religiosity on the disability, psychological well-being, and somatic health of multiple sclerosis patients

Abstract
The aim of the study was to predict disability, psychological wellbeing, and somatic health in multiple sclerosis (MS) patients with the mediating variable of religiosity. A sample of 128 patients was recruited, and were administered the Expanded Disability Status Scale, the World Health Organization-5 Well-Being Index, the Patient Health Questionnaire-15, and a Self-Rating Scale of Religiosity. Religiosity did not predict disability, psychological well-being, or somatic health. Religiosity was positively associated with MS duration and disability, but only in male patients. The predictors for predicting psychological wellbeing were age, disability, and somatic health. Patients with...

Abstract
Despite the importance of well-being, few studies have been conducted on the relationship between well-being and technology. In this paper, the development of technology from the perspective of well-being studies are divided into three generations. In higher generations, the main criterion of technology development becomes more comprehensive, in order to decrease the side effects of technology. We introduce the fourth generation in which well-being is the main criterion of the design process. Although it may not seem necessary to say that the purpose of most technologies is implicitly well-being, we show that the domination of physical pleasure in terms of “use and convenience” in the modern...

Abstract
In spite of the widespread applications of probabilistic criteria in large systems there is considerable reluctance to apply probabilistic techniques in small isolated power systems. This reluctance dictates a need to create a bridge between the conventional deterministic methods and the prevalent probabilistic techniques. This paper presents a well-being approach to illustrate the adequacy assessment of small isolated power systems. A well-being index designated as LORE and the conventional LOLE index are utilized to determine the maximum load carrying capability in two isolated systems. Copyright ©2003 IFAC
Composite system well-being analysis using sequential Monte Carlo simulation and fuzzy algorithm
, Article Istanbul University - Journal of Electrical and Electronics Engineering ; Volume 13, Issue 1 , Dec , 2013 , Pages 1575-1580 ; 13030914 (ISSN) ; Fotuhi Firuzabad, M ; Parvania, M ; Sharif University of Technology

Abstract
Well-Being reliability indices (Health, Margin and Risk), provide a comprehensive measure to assess the adequacy of composite power systems. Conventional reliability information about power system operation only considered health and risk states, which were not often adequate criteria in both power system planning and operation. Well-being approach for power system generation adequacy evaluation incorporates deterministic criteria in a probabilistic framework, and provides system operating information in addition to risk assessment and can be evaluated using analytical techniques. The most important part of this approach is the algorithm for calculating the probability of the states....

Abstract
A novel pool-based market-clearing algorithm for spinning reserve (SR) procurement and the cost allocation associated with provision of spinning reserve among customers (DisCos) is developed in this paper. Rational buyer market model is used to clear energy and spinning reserve markets in the proposed algorithm. This market model gives DisCos the opportunity to declare their own energy requirement together with their desired reliability levels to the ISO and also they can participate in the SR market as a interruptible load. The DisCos' desired reliability levels are selected from a hybrid deterministic/probabilistic framework designated as the system well-being model. Using the demand of...
