    The Effect of Ownership Structure and Board Composition as Corporate Governance Mechanisms on Coroporate Value

    , M.Sc. Thesis Sharif University of Technology Sadighian, Amir Hossein (Author) ; Mashayekhi, Ali Naghi (Supervisor)
    Abstract
    In this research we examine the effects of internal corporate governance mechanisms on shareholder value of 247 firms that were accepted in Tehran Stock Exchange. The main focus is on ownership structure and board composition. Owners with different identities affect shareholder value both directly and to some extent indirectly (through affecting board composition). We measured firm value using 2 different measures: relative growth of share price and market to book value of the firm. Controlling for industry effects, considering different levels of competitiveness, we find that private owners affect firm value more positively than governments and so do institutional investors more than...

    Studying Impediments Social Learning in Economic Policymaking Community of Iran

    , M.Sc. Thesis Sharif University of Technology Ahmadpour Samani, Narjes (Author) ; Mashayekhi, Ali Naghi (Supervisor)
    Abstract
    Social learning approach in economic policymaking is introduced against conflict-based approach in the similar context. Helco, 1973 first studied the effects of such a learning in economic policymaking and said ”men collectively wondering what to do… Governments not only ‘power’… they also puzzle.” The important point in studying policymaking through social learning approach is paradigm shifts in peoples’ mental models. In this approach, policies are not only the result of conflict between different interests but also are the output of a learning process. In this research we first assume that social learning has not occurred in policymaking community and that individual learning has... 

    Parallel Layers of Strategic Renewal and the Leveraging Role of Organizational Structure

    , Ph.D. Dissertation Sharif University of Technology Aghajanian, Simineh (Author) ; Mashayekhi, Ali Naghi (Supervisor) ; Alavi, Babak (Co-Supervisor)
    Abstract
    One of the research areas less-addresses in the field of strategy – especially with a process approach – is strategic renewal. Strategic renewal is crucial for sustainable success of an organization. However, there are limited studies focused on strategic renewal, its implementation, and factors affecting its successive success. Process view is also less applied despite its importance both in understanding different steps of renewal and determining motivators and impediments. Therefore, this study tries to do a process-oriented research on strategic renewal, considering the gaps in extant process models on renewal. For this aim, an embedded single case study is applied and some successful...

    Agency and Large-Scale Institutional Changes; The Study of the Creation of the Biopharmaceutical Industry in Iran

    , Ph.D. Dissertation Sharif University of Technology Babaei، Ali (Author) ; Mashayekhi, Ali Naghi (Supervisor) ; Miremadi, Iman (Supervisor) ; Maleki, Ali (Co-Supervisor)
    Abstract
    Neither state planning nor economic liberalization has been the answer for developing countries to escape from the middle-income trap, mainly due to presence of institutional voids and due to the governance of hindering institutions. Therefore, we need another explanation for how of the development, which must include how institutions change and how new institutions and new institutional fields emerge. Developing countries are full of institutional voids and the governance of hindering institutions. Therefore, the process of economic development in these countries, is beyond the power of market and state, and needs agency. Responding to the recent call by the literature for doing more...

    A Study on Readiness for Change in Project-Based Organizations that are Establishing a Project Management Office (PMO)

    , M.Sc. Thesis Sharif University of Technology Tabatabei Lotfi, Mir Hossein (Author) ; Mashayekhi, Ali Naghi (Supervisor) ; Alavi, Babak (Supervisor)
    Abstract
    A great rise in the number of projects undertaken simultaneously within organizations and consequently, a further increase in the complexity of managing them, has led to emerging innovative forms of organizational structures. There are new concepts developing in project management literature such as program management, portfolio management and project management offices (PMOs). PMOs have recently been used as a means for managing large projects, based on the need for an overall, coherent approach. Project offices are established to coordinate portfolios of projects and achieve project management oversight, control and support. Based on the structure and definition proposed by Hill (2004), it... 

    Investigating Factors Affecting Petrochemical Value Chain Completion and Policies for Improvement

    , M.Sc. Thesis Sharif University of Technology Pakfetrat, Anahita (Author) ; Maleki, Ali (Supervisor) ; Mashyekhi, Ali Naghi (Supervisor)
    Abstract
    Despite the growth in Iran’s petrochemical production, most of the plants are concentrated upstream; although the government has made various interventions to promote industrial development. The literature review shows that government intervention is necessary to solve market failures, especially in developing countries; but it should be tailored to the specific context and especially the distribution of the power. Most experts believe that the cause of the above phenomenon is feedstock rent and the reason for its continuation is the political influence of petrochemical companies. While not rejecting this view, we try to provide policy recommendations by looking more closely at the issue and... 

    Improvement of Stability of Haptic Force Interaction with Virtual Environments Using a Haptic Interface with a Separate Tracker

    , M.Sc. Thesis Sharif University of Technology Mashayekhi, Ahmad (Author) ; Meghdari, Ali (Supervisor) ; Nahvi, Ali (Supervisor)
    Abstract
    In the present study, a new version of haptic devices is presented in which user’s hand is in contact with the device just while collision with virtual surface. In this system, the position of user’s finger can be traced by using a camera and the haptic device follows user’s finger at the distance of about two centimeters. While the haptic device approaches to the virtual surface, gradually reduces its speed and stops about two centimeters distant of virtual plane. Then user’s hand collides with the haptic device which is static. Greater fidelity, transparency, more stability and also no need to large actuators are of the advantages of this system. In this project, first we present a new...

    Project cost dynamics for development policy-making

    , Article Journal of the Operational Research Society ; Volume 51, Issue 3 , 2000 , Pages 301-310 ; 01605682 (ISSN) Mashayekhi, A. N ; Sharif University of Technology
    2000
    Abstract
    Cost and time overruns have been a common characteristic of development projects in many countries. This paper presents a theory of cost and time overruns based on project cost structure. The cost of a development project consists of base cost and progress cost. Base cost keeps a project ready for physical progress. Progress cost creates real physical progress on the project. This cost structure has an important inherent dynamic characteristic with implications for the efficiency and effectiveness of project management. An imbalance between annual budget and ongoing projects results in an increasing inefficiency and ineffectiveness unrelated to the quality of management of individual...

    , Article Peer-to-Peer Networking and Applications ; Vol. 7, issue. 2 , 2014 , Pages 199-212 ; ISSN: 19366442 Mashayekhi, H ; Habibi, J ; Sharif University of Technology
    2014
    Abstract
    Efficient storage and handling of data stored in a peer-to-peer (P2P) network, proves vital for various applications such as query processing and data mining. This paper presents a distributed, scalable and robust layered overlay (L-overlay) to index and manage multidimensional data in a dynamic P2P network. The proposed method distinguishes between the data and peer layers, with efficient mapping between the two. The data is organized such that semantically similar data objects are accessed hastily. Grid and tree structures are proposed for the peer layer. As application examples of L-overlay in query processing and data mining, k-nearest neighbors query processing and distributed Naïve... 

    Uniquely decodable codes with fast decoder for overloaded synchronous CDMA systems

    , Article IEEE Transactions on Communications ; Volume 60, Issue 11 , 2012 , Pages 3145-3149 ; 00906778 (ISSN) Mashayekhi, O ; Marvasti, F ; Sharif University of Technology
    2012
    Abstract
    In this paper, we introduce a new class of sigature matrices for overloaded synchronous CDMA systems that have a very low complexity decoder. While overloaded systems are more efficient from the bandwidth point of view, the Maximum Likelihood (ML) implementation for decoding is impractical even for moderate dimensions. Simulation results show that the performance of the proposed decoder is very close to that of the ML decoder. Indeed, the proposed decoding scheme needs neither multiplication nor addition and requires only a few comparisons. Furthermore, the computational complexity and the probability of error vs. Signal to Noise Ratios (SNR) are derived analytically  

    K-nearest neighbor search in peer-to-peer systems

    , Article AP2PS 2010 - 2nd International Conference on Advances in P2P Systems ; 2010 , Pages 100-105 ; 9781612081021 (ISBN) Mashayekhi, H ; Habibi, J ; Sharif University of Technology

    Abstract
    Data classification in large scale systems, such as peer-to-peer networks, can be very communication-expensive and impractical due to the huge amount of available data and lack of central control. Frequent data updates pose even more difficulties when applying existing classification techniques in peer-to-peer networks. We propose a distributed, scalable and robust classification algorithm based on k-nearest neighbor estimation. Our algorithm is asynchronous, considers data updates and imposes low communication overhead. The proposed method uses a content based overlay structure to organize data and moderate the number of query messages propagated in the network. Simulation results show that...
