Hybrid test for the hypothesis of symmetry
No full textIn recent years, McWilliams and Tajuddin have proposed new and more powerful non-parametric tests of symmetry for continuous distributions about a known center. In this paper, we propose a simple non-parametric two-stage procedure based on the sign test and a percentile-modified two-sample Wilcoxon test. The small-sample properties of this test, Tajuddin's test, McWilliams' test and a modified runs test of Modarres and Gastwirth are investigated in a Monte Carlo simulation study. The simulations indicate that, for a wide variety of asymmetric alternatives in the lambda family, the hybrid test is more powerful than are existing tests in the literature.
Mr. Hasan Modarres and his political role in Iran 1870-1937 AD
No full textThe personality of Mr. Ayatollah Hassan Modarres is one of the well-known Iranian religious and political figures, and his role has clearly emerged since the events of the Iranian Constitutional Movement (1905-1911 AD), where he had a clear role in all of those events, then the activity of Mr. Hassan Modarres expanded during the years of the First World War And beyond, to constitute a vital element in combating tyranny and injustice that Iranian society was suffering from, due to the foreign presence in the country and its consolidation and support for the armed resistance movements that Iran witnessed during those years, perhaps foremost among which was the movement of the Gilan region. Mr. Mudarres also had a clear role in the period that followed the First World War and his resistance and leadership of the demonstrations calling for the independence of Iran and the exit of the foreign occupation, especially the British, from Iran. Adversaries of the policy of Iranian governments. Mr. Mudarres completed his role even after the dissolution of the Qajar family and Reza Shah Pahlavi's accession to power. However, the history of his struggle during the rule of that family did not last long, so he was soon physically liquidated by the Iranian security forces and at the personal behest of Shah Reza Pahlavi, thus turning the page of his bitter jihad and struggle .
The research is divided into an introduction, three sections, and a conclusion. The first section sheds light on the family in which Mr. Mudarres was raised and his religious and scientific upbringing, while the second section sheds light on the role of Mr. Mudarres in the midst of the events that Iran witnessed during the period 1905-1918 AD. The third is the struggle of Mr. Modarres and his opposition to foreign policy trends in Iran until his death in 1937 AD.
The research relied on many published Persian documents such as statements, letters, and reports that dealt in detail with the role of Mr. Mudarres in very important Iranian events. The research also relied on a wide range of Persian and Arabic books and references, and a number of English and other sources
Survey of the Key Methods of Improving Public Trust to Government
No full textSurveyoftheKeyMethodsofImprovingPublicTrusttoGovernment Hasan Danaee Fard* - Ali Reza Hasanzadeh** - Somayeh Nasroallahi*** (Received: 2014/April/17 – Accept: 2014/Octobr/27) Abstract Public Trust is considered as a strategic capital of any political system. Accordingly, one of the main challenges facing governments is “public Trust management”. The governments should use mechanisms to achieve this objective. The final goal of this research is to suggest mechanisms for public Trust promoting to the Iranian government. It is provided in mix method. In the first stage, the mechanisms are provided through reviewing and a scale is developed along taken mechanisms and in the second stage, such scale is justified by public. Finally, 38 determined mechanisms are classified in 5 categories. The main ones are: social equity in using public service, making political and economic peace, and existence of efficient judicial institution. It is also analyzed the gap between the current and desired situation using the mechanisms in which there is significant difference between them in all identified mechanisms. *Associate Professor of Public Administration, Tarbiat Modarres University [email protected] **Associate Professor of Information Technology Management, Tarbiat Modarres University [email protected] ***Master of Public Administration, Tarbiat Modarres University [email protected] (corresponding author
Further aspects of the tests of the equality of correlation matrices
No full textA common problem in social, educational, behavioral and biological research is to investigate relationships between variables across several groups. Factor analysis is one such procedure with a long history of use. A more modern graphical procedure is the biplot of Gabriel (1971). Biplots result in a graphical display of correlation structure.We present results that extend an existing test of equality of correlation matrices. A new test statistic is proposed and is shown to be asymptotically distributed as a linear combination of independent \chi\sp2 random variables. This new formulation allows us to find the power of the existing test and our extensions by deriving the distribution under the alternative as that of a linear combination of independent non-central \chi\sp2 random variables.We also investigate the null and the alternative distributions of two related statistics. The first test statistic is defined as a quadratic form in deviations from a control group with the remaining K-1 groups to be compared. The second test is designed for comparing adjacent groups.In order to find a simple and accurate approximation for our statistics, we discuss several methods of approximating the distribution function of a definite quadratic form in normal variates. In particular, we investigate the two moment, the three moment, and the normal approximations. We also consider an approximation technique due to Imhof (1961).A Monte Carlo study is presented to assess the robustness of our procedure and the likelihood ratio test. We show that aside from the computational difficulties associated with the likelihood ratio test, this test is very sensitive to the assumption of multivariate normality. We also show that our test statistic performs well under non-normal distributions. To illustrate the techniques and assess the applicability of our procedure, we present several examples.Source: Dissertation Abstracts International, Volume: 51-05, Section: B, page: 2442.Advisors: Robert W.

Tests of Bivariate Exchangeability
No full textWe discuss the hypothesis of bivariate exchangeability and show that testing bivariate exchangeability is related to the two-sample testing of equality of distribution functions. We consider three test statistics based on the ordering of the Euclidean interpoint distances. The runs test of exchangeability counts the runs among the observations and their mirror images on the minimal spanning tree. The nearest neighbour test of exchangeability is based on the number of nearest neighbour type coincidences among the observations and their folded images on the plane. The rank test of exchangeability compares the within and between ranks of the interpoint distances. We also consider the sign test of exchangeability, which uses the signs of the observations in specific regions, and a bootstrap test of exchangeability based on the maximum distance between the mirror images. We compare the power of these methods in a Monte Carlo study which shows different power orderings of the methods, depending on the alternative hypothesis. Copyright (c) 2008 The Author.

A Comparative Study of Narration Levels and Its Elements in the Stories of Surah the Cave (Al-Kahaf)
No full textNarrationology is regarded as a theoretical and practical framework and pattern to examine and analyze various types of stories, including Quranic ones. Using narrationology and its theories such as narrative levels, plot, story, narrative text, narrative method of stories, meanings and foundations is regarded an efficient method to analyze Quranic stories. The Surah Cave includes three specific stories, including the story of the people of the Cave, the story of Prophet Musa and Khezr and the story of Dhul-Qarnayn "he of the two horns." The results of the present paper shows that the narrative plot of the stories in the Surah Cave is noticeable in terms of continuous construction methods of various narrative levels, integration and interconnectivity of these levels with each other, successive fractions in story line and episodic analysis of stories in appearance and their integrity in the inner part of the Surah.

مسافر : Mosafer (the Traveller)
No full textThis thesis poses questions about the preservation of culture and language amongst generations of Iranian immigrants living in North America. It investigates the socio-cultural implications of hybridity as they relate to interethnic exchange and the globalizing process of travel and translation. Working with notions of “third space” or “the space in-between” (Clifford,1992; Bhabha, 1994) and Farzad Sharifian’s research on the globalization of English (2012), this work explores how the use of the hybrid language Persian-English affects an Iranian sense of identity in a globalized world. Susan Stewart’s discussion on the agency of objects to generate narratives which are central to a cultural experience (1993) is discussed as it applies to the use of objects in the artworks being examined in this paper. An analysis of several contemporary autoethnographic works from recent art history, such as Mona Hatoum’s Measures of Distance (1988), Zineb Sedira’s Mother Tongue (2002), and Ala Ebtekar’s Elemental (2004), is used to form a basis for a discussion of hybrid identity and how inherited language can complicate cultural exchange. The artistic projects that come out of this research are Ma Miaeem va Miravim (We Come and Go), 2016, and Soghat (Souvenir), 2017. Ma Miaeem va Miravim (We Come and Go) is an artist book based on the first-grade English book, We Come and Go (1954), which employs a hybrid translation of Persian-English—in which Persian words are written using the Roman alphabet. Soghat (Souvenir) is a series of sculptures made from everyday objects and string, which investigates how culture travels through objects. These artworks are discussed to explore ways in which meaning can be lost, gained, or altered, through the substitution of signifiers and the co-mingling of cultures

Spatial patterns and temporal trends of daily precipitation indices in Iran
No full textSpatial patterns of daily precipitation indices and their temporal trends over Iran are
investigated using the APHRODITE gridded daily precipitation dataset for the period 1961–
2004. The performance and limitations of the gridded dataset are checked against observations
at ten rain-gauge stations that are representative of different climates in Iran. Results suggest
that the spatial patterns of the indices reflect the role of orography and sea neighborhoods in
differentiating central-southern arid and semi-arid regions from northern and western mountainous
humid areas. It is also found that western Iran is impacted by the most extreme daily
precipitation events occurring in the country, though the number of rainy days has its
maximum in the Caspian Sea region. The time series of precipitation indices is checked for
long-term trends using the least squares method and Mann-Kendall test. The maximum daily
precipitation per year shows upward trends in most of Iran, though being statistically significant
only in western regions. In the same regions, upward trends are also observed in the
number of wet days and in the accumulated precipitation and intensity during wet days.
Conversely, the contribution of precipitation events below the 75th percentile to the annual
total precipitation is decreasing with time, suggesting that extreme events are responsible for
the upward trend observed in the total annual precipitation and in the other indices. This
tendency towards more severe/extreme precipitation events, if confirmed by other datasets and
further analyses with longer records, would require the implementation of adequate water
resources management plans in western Iran aimed at mitigating the increasing risk of intense
precipitation and associated flash floods and soil erosion
