Impacts of Aggregation on Relative Performances of Nonsurvey Updating Techniques And Intertemporal Stability of Input–Output Coefficients

In many instances, and for variety of reasons, input–output researchers are compelled to both employ mechanical techniques to update older survey-based tables as well as using more aggregated ones. This combination, however, gives rise to several concerns. The present paper is an attempt to investigate two such questions. First, the effects of aggregation on the accuracy ranking of selected updating methods, and second, the effects of aggregation on intertemporal stability of the input–output coefficients. To probe these issues, three updating methods were selected. These methods are NAÏVE or constant coefficient hypothesis, RAS or biproportional method, and LaGrangian optimization technique. Two survey-based tables from the former Soviet Union along with the selected updating techniques are used to generate updated target year’s direct and inverse transaction matrices at four aggregation levels. Comparison of the resultant estimates at these four levels of aggregation with their counterparts in the actual benchmark table reveals that a higher level of aggregation neither affects the rankings of the updating methods nor does it universally and unequivocally leads to a higher degree of intertemporal stability of input–output coefficients.     

Trends in Public Administration Research: A Content Analysis of Iranian Journal Articles (2004-2017)

This study aims to examine the trends of public administration research in Iran during 2004–2017. A total of 520 articles from three databases have been reviewed and analyzed using content analysis. Results are reported based on research themes, purposes, orientations, methods, and authorship. Comparisons are made across two time spans and by journal type. Findings indicate that the focus of public administration research has been on issues of public administration, Islam and public administration, administrative performance, and organizational behavior in the public sector. Observations reveal that recent Iranian research studies have more explanatory purposes and often apply qualitative methods. The study also concludes that the Iranian public administration research has advanced considerably over the past 14 years, but more efforts are needed to fill in the gap in such important areas as new public service, civic participation, globalization, policy making, sound governance, and policy implementation.     

Islamic Identity,Nationality and Republicanism in the Process of Islamic Awakening

This paper is going to identify and discuss necessary theoretical principles for reasoning current and future situation of subjects related to Arabic Islamic thoughts. This paper tries to consider typology of vocal groups at Islamic movements involved in the process of Islamic awakening. In this direction, firstly different research approaches will be considered and the main purpose is that how these researches observe the origin of formation of these groups and what is their emphasis in this regard. The key points of their reasoning will be explained and then the explanation, representation and re-definition of these groups are paid attention to. The main idea is that among all analyses and reasoning and view points, the key point is the importance of viewpoint of Islamism in these movements and any analysis will be unreliable reading without reading to this variable,
