Islamists and democracy in Sudan: the role of Hasan Turabi, 1989-2001
Creators: name: Mohammed, Suhair
Publisher: name: University of Westminster
Year: 2012

description: This research assesses the experiment of the Islamic movement in Sudan following the 1989 coup. The main question that needs to be answered with regard to Turabi and the Islamists in Sudan is the gap between theory and practice. Sudan is a complex country, with a diverse population encompassing different tribes, languages, religions and cultures, all impacting on the country’s history and future. Consequently, the Islamic movement was influenced by the nature of this society. The Islamisc movement in Sudan was established in the 1940s, linked to the Muslim Brotherhood in Egypt, and to revivalists in the 19th and 20th centuries, such as al-Afghani, Mohammed ‘Abdu, Mawdudi, Hasan al-Turabi and Rashid al-Ghannouchi. The research assesses the theories of Turabi in Shura, democracy and issues of government. It critically evaluates the concepts of Tawhīd, the state in Islam, and human rights, minorities, women, etc., in the Islamic state. This research established that gaps existed between the theory and practice of Turabi and the Islamists in Sudan. Their military coup represents the first violation of democracy. They possessed a clear human rights’ vision, but in practice violated them from the early days of the coup. They developed mature theories on power sharing, justice and equality, but have monopolised power since 1989. Shura was implemented in the movement institutions, but remains to be enhanced in the State. In the first decade, Islamist succeeded in developing the economic sector, by exploring for oil, and establishing a free market, but with no mechanisms to mitigate its negative side-effects. In society, significant laws were developed, in favour of women, education, and media. One may argue that Islamists need to take further steps towards Shura and democracy on the practical level, and establish proper mechanisms.
On the Hirzebruch-Kobayashi-Ono proportionality principle and the non-existence of compact solvable Clifford-Klein forms of certain homogeneous spaces

description: This article continues a line of research aimed at solving an important problem of T. Kobayashi of the existence of compact Clifford-Klein forms of reductive homogeneous spaces. We contribute to this topic by showing that almost all symmetric spaces and 3-symmetric spaces do not admit solvable compact CliffordfKlein forms (with several possible exceptions). Our basic tool is a combination of the Hirzebruch-Kobayashi-Ono proportionality principle with the theory of syndetic hulls. Using this, we prove a general theorem which yields a sufficient condition for the non-existence of compact solvable CliffordKlein forms.

description: We consider the spatial central force problem with a real analytic potential. We prove that for all analytic potentials, but the Keplerian and the Harmonic ones, the Hamiltonian fulfills a nondegeneracy property needed for the applicability of Nekhoroshev's theorem. We deduce stability of the actions over exponentially long times when the system is subject to arbitrary analytic perturbation. The case where the central system is put in interaction with a slow system is also studied and stability over exponentially long time is proved.

description: For Brownian motion in a (two-dimensional) wedge with negative drift and oblique reflection on the axes, we derive an explicit formula for the Laplace transform of its stationary distribution (when it exists), in terms of Cauchy integrals and generalized Chebyshev polyno-mials. To that purpose we solve a Carleman-type boundary value problem on a hyperbola, satisfied by the Laplace transforms of the boundary stationary distribution.
Russian small businesses: entrepreneurship in transition. Exploratory investigation of the factors that pushed and pulled individuals to open their own business in the Krasnodar region of Russia
Creators: name: Mityay, Evgeniya
Publisher: name: University of Westminster
Year: 2012

description: The purpose of this research was to identify the factors that pushed and pulled individuals to become self-employed in Russia during the post-Soviet Union period. The research methodology adopted in this study was qualitative. The longitudinal multiple case study approach was comprised of in-depth interviews with the founders and co-founders of 26 family businesses in the Krasnodar region of Russia. To summarise particular findings of the present research one push factor and four pull factors have been identified as being the most influential: 1. ‗Unemployment / Restructuring‘ during the transitional period push factor; 2. ‗The Demand for Local Services‘ pull factor; 3. ‗The Development of Entrepreneurial Skills‘ pull factor; 4. The ‗Cultural Changes‘ pull factor; and 5. The ‗Family Relatedness‘ pull factor. This thesis postulates that a contribution to the understanding of the push-pull debate theory can be made through an interpretation of the factors that influence individuals‘ decisions to become self-employed. A significant body of worldwide research currently exists that deals with the concept of the self-employment push-pull debate. There is however no one agreed view on which factors push or pull individuals to become self-employed. An analysis of various literature sources has at times revealed contradictions and inconsistencies within this debate. This observation can be partly explained by the fact that this body of research exists across a diverse range of countries and through time. This thesis highlights the fact that a clear dichotomy of the self-employment push and pull factors may not always be adequate. This analysis highlights that what really matters when identifying the factors that push or pull individuals to become self-employed is how the individuals themselves interpret these factors. Therefore any factor potentially could be considered as being both push and pull depending upon the individual‘s personal interpretation.

Molecular gas and dust extinction relation revealed by ALMAQUEST
Creators: name: Concas, Alice
Publisher: name: Zenodo
Year: 2023

description: The relation between the molecular gas content and the dust screen surrounding HII regions is a powerful tool for galaxy evolution studies. In this talk, I will show how to explore such relation on a sample of 46 nearby galaxies in the framework of the ALMaQUEST (ALMA-MaNGA QUEnching and STar formation) survey, combining new CO(1-0) maps with kpc resolution from ALMA observations with IFU spectroscopic datacubes from MaNGA. I will show the existence of the empirical relation between the molecular gas surface density traced by the CO(1-0) luminosity and the dust extinction inferred by the Balmer Decrement (BD=Hα/Hβ) on a kiloparsec scale. I will discuss the possibility to use the BD to probe the spatially resolved distribution of cold gas in nearby galaxies in the absence of direct submillimeter observations.

description: Semilinear stochastic partial differential equations on bounded domains $\mathscr{D}$ are considered. The semilinear term may have arbitrary polynomial growth as long as it is continuous and monotone except perhaps near the origin. Typical examples are the stochastic Allen--Cahn and Ginzburg--Landau equations. The first main result of this article are $L^p$-estimates for such equations. The $L^p$-estimates are subsequently employed in obtaining higher regularity. This is motivated by ongoing work to obtain rate of convergence estimates for numerical approximations to such equations. It is shown, under appropriate assumptions, that the solution is continuous in time with values in the Sobolev space $H^2(\mathscr{D}')$ and $\ell^2$-integrable with values in $H^3(\mathscr{D}')$, for any compact $\mathscr{D}' \subset \mathscr{D}$. Using results from $L^p$-theory of SPDEs obtained by Kim~\cite{kim04} we get analogous results in weighted Sobolev spaces on the whole $\mathscr{D}$. Finally it is shown that the solution is Hölder continuous in time of order $\frac{1}{2} - \frac{2}{q}$ as a process with values in a weighted $L^q$-space, where $q$ arises from the integrability assumptions imposed on the initial condition and forcing terms.

This is achieved by first establishing closed formulae of the $\imath$-divided powers in basis for quantum $\mathfrak{sl}_2$ and then formulae for the $\imath$-canonical basis in terms of Lusztig's divided powers in each finite-dimensional simple module of quantum $\mathfrak{sl}_2$. These formulae exhibit integrality and positivity properties.

description: Early Medieval Finds from Czechowice (Gliwice / PL) Several Polish and German institutions have preserved in their collections archival documents containing information relating to the accidental discovery of Early Medieval objects in the village of Czechowice (now within the city limits of Gliwice) in Upper Silesia. The artefacts, found in 1879 during the construction of a railway, were acquired by the Königliches Museum für Völkerkunde in Berlin and lost during World War II. Only recently, some of them have been identified in the collection of the Museum für Vor- und Frühgeschichte in Berlin. The most important finds include a long, straight, single-edged sword representing a hybrid Old Hungarian-type weapon and a narrow hammer-axe of the Moravian type. Both pieces were discovered at the same place and probably belonged to the equipment of an inhumation grave dated to around the mid-10th century.

Bergstraße) sind die ostfränkischen Könige Ludwig II. der Deutsche († 876) und Ludwig III. der Jüngere († 882) bestattet worden. Ihre Gräber gelten als verschollen, seit das Kloster 1621 im Dreißigjährigen Krieg fast völlig zerstört wurde. Zwei Augenzeugenberichte der damaligen Zeit sowie Befunde und Funde von Ausgrabungen erlauben aber den Schluss, dass Ludwig II. in dem riesigen Porphyrsarkophag ohne Inschrift beigesetzt worden war, der sich in der Krypta / Grabkirche hinter dem Chor der Basilika befunden hatte. Sein Sohn Ludwig III. ruhte in dem ringsum mit den Flachreliefs ionischer Pilaster verzierten Pilastersarkophag, der auf Säulchen im Mittelschiff gestanden und bei seiner Entdeckung im Jahre 1800 noch den ungestörten Leichnam dieses Königs enthalten hatte. Ludwig III. trug ein braun (?) kariertes Seidengewand mit Goldborten sowie Stiefel mit Sporen, von denen noch ein goldener Riemenschieber vorhanden ist. Diese wertvolle Beschreibung eines spätkarolingischen Königsgrabes ist dem Oberforstmeister und laienhaften Ausgräber Carl Freiherr von Hausen zu verdanken.

Shifts in the relationship between the state and civil society in Brazil’s recent democracy
Creators: name: Koga, Natalia
Publisher: name: University of Westminster
Year: 2012

description: This thesis investigates the shifts in the relationship between the state and civil society in Brazil between 1995 and 2010. Following a period when ‘civil society’ was nearly abandoned as an analytical category, a number of studies from the 1980s onwards have developed links between ideas of democracy and civil society. Seeking to understand the roles played by civil society and their relevance for Brazil’s recent democracy, this work proposes an analytical framework that associates a relational approach with the application of analytical tools from Chantal Mouffe’s agonistic theory of democracy. The thesis’ period of analysis covers the administrations of presidents Fernando Henrique Cardoso and Luiz Inácio Lula da Silva. The main hypothesis examined is that during this period there occurred a shift from an ‘apoliticalconsensual’ to a ‘political-conflictual’ pattern of relationship between state and civil society. The work undertaken in this investigation is conveyed through eight sections. Following a brief introduction, Chapter 1 is dedicated to a review of the literature on civil society; it also includes a justification of the use of the relational approach and an introduction to this thesis’ main analytical categories. Chapter 2 traces an overview of the historical trajectory of civil society in Brazil and its key characteristics. Chapter 3 explores the discourses and practical measures relating to civil society which have been adopted by the Cardoso and Lula governments. Chapter 4 discusses the literature on participation in Brazil and its formulations on the modes of interaction between the state and civil society. It also explores tenets of Mouffe’s agonistic theory and proposes an analytical framework through which the case studies will be interpreted. Chapters 5 and 6 examine the two selected case studies: respectively, the National Council for Health and the 1st National Conference of Communications. The concluding chapter outlines the thesis’ main findings. This thesis intends to expand understanding of the realms of civil society action; the forms of relationship between civil society organisations and the state; and, finally, the projects’ potentialities for expanding participation and deepening democracy in Brazil.

description: The enzyme Dicer is a component of many small RNA (sRNA) pathways involved in RNA processing for post-transcriptional regulation, anti-viral response and control of transposable elements. Cleavage of double-stranded RNA by Dicer produces a signature overhanging sequence at the 3' end of the sRNA sequence relative to a complementary passenger strand in a RNA duplex. There is a need for reliable tools to computationally search for Dicer cleavage signatures to help characterise families of sRNAs. This is increasingly important due to the rising popularity of sRNA sequencing, especially in non-model organisms. Here, we present stepRNA, a fast, local tool that identifies (i) overhang signatures strongly indicative of Dicer cleavage in RNA sequences, and (ii) the length of the passenger strand in sRNAs duplexes. We demonstrate the use of stepRNA with simulated and biological datasets to detect Dicer cleavage signatures in experimentally validated examples. Compared to currently available tools, stepRNA is more accurate, requires only sRNA sequence data rather than a reference genome, and provides information about other important features such as passenger strand length. stepRNA is freely available at https://github.com/Vicky-Hunt-Lab/stepRNA and is easily installable.

Diese Mühlenachse stammt wahrscheinlich aus römischer Zeit und gehörte zu einer Getriebemühle. Getriebemühlen unterscheiden sich von einfachen Mühlen durch ein festes Getriebe mit zwei Getrieberädern, durch die die eingespeiste Kraft übersetzt und die Leistung der Mühle erhöht wird. Die Entwicklung der Getriebemühlen erfolgte vermutlich im 2. Jahrhundert n. Chr.; sie sind bislang in Deutschland, England, Rumänien und Ungarn durch entsprechende Mühleisen nachgewiesen. Mit dem Fund aus Doliche liegt nun auch ein Nachweis aus dem Ostmediterraneum vor. Noch kann der Standort der Mühle in Doliche nicht lokalisiert werden, aber es ist zu vermuten, dass sie in einer Bäckerei im Zentrum der Stadt betrieben wurde.

Ces tombes pourraient correspondre à un ensemble funéraire familial en relation avec une villa située à proximité. Découverte au Sud du monument funéraire, la sépulture DP 5294 est un dépôt mixte de crémation, pour un individu probablement féminin, daté entre 60–100 apr. J.-C. Cette tombe a livré un mobilier assez abondant, dont une série de miniatures en plomb, une paire de sandales attachée à une patère et un lot de strigiles sur leur anneau.

description: We consider the family of irreducible crystalline representations of dimension $2$ of ${\rm Gal}(\overline{\bf Q}_p/{\bf Q}_p)$ given by the $V_{k,a_p}$ for a fixed weight integer $k\geq 2$. We study the locus of the parameter $a_p$ where these representations have a given reduction modulo $p$. We give qualitative results on this locus and show that for a fixed $p$ and $k$ it can be computed by determining the reduction modulo $p$ of $V_{k,a_p}$ for a finite number of values of the parameter $a_p$. We also generalize these results to other Galois types.

description: Un »cold case« irritant: les mandibules humaines de la Grotte de Han à Han-sur-Lesse (Rochefort, prov. Namur / BE) C’est à l’occasion de fouilles menées en 1964–1965 par M.-E. Mariën sur la Plage des Petites Fontaines de la Grotte de Han, à Han-sur-Lesse (Belgique), que fut découvert, dans un niveau attribué à la fin de l’âge du Fer, un dépôt de sept mandibules humaines. Dès le départ, ces vestiges ont été considérés comme provenant de têtes coupées, mais sur la seule base d’un examen préliminaire réalisé peu après la découverte et qui jusque-là n’avait jamais été validé par une analyse détaillée. Par ailleurs, une série de datations directes par le radiocarbone, effectuée au début des années 2000, semblait montrer qu’ils datent de différentes périodes allant de La Tène moyenne au début de l’époque romaine, donc un dépôt postérieur à l’âge du Fer. L’étude approfondie des mandibules que nous avons réalisée montre tout d’abord que si l’examen préliminaire était en grande partie erroné, plusieurs portent bien des marques attestant des décapitations, venant ainsi confirmer ce qui était présumé. D’autre part, une partie d’entre elles présente des atteintes thermiques témoignant probablement d’une exposition au feu de têtes complètes et encore pourvues de leurs chairs. Parallèlement, une nouvelle série d’analyses radiocarbone a été effectuée, dont les résultats sont partiellement en contradiction avec ceux des analyses antérieures, ce qui conduit à mettre en doute l’ensemble des datations. Il n’est dès lors possible ni d’affirmer que les mandibules sont d’âges différents ni de dater directement leur dépôt, qui aurait eu lieu à La Tène C ou D si l’on s’en tient au terrain. Plusieurs arguments sont en faveur d’un dépôt des seules mandibules, effectué en une seule fois et assez rapidement après le décès. Nous ne savons par contre rien du devenir du reste des têtes, mais rien n’indique qu’elles aient été apportées dans la grotte. Enfin, si le dépôt a probablement une dimension cultuelle, on ne saurait en dire plus sur sa signification. Finalement, malgré quelques certitudes, cette découverte intrigante, qui reste unique, continue aujourd’hui de résister à l’interprétation.

description: We give a uniform description of the bijection $Φ$ from rigged configurations to tensor products of Kirillov--Reshetikhin crystals of the form $\bigotimes_{i=1}^N B^{r_i,1}$ in dual untwisted types: simply-laced types and types $A_{2n-1}^{(2)}$, $D_{n+1}^{(2)}$, $E_6^{(2)}$, and $D_4^{(3)}$. We give a uniform proof that $Φ$ is a bijection and preserves statistics. We describe $Φ$ uniformly using virtual crystals for all remaining types, but our proofs are type-specific. We also give a uniform proof that $Φ$ is a bijection for $\bigotimes_{i=1}^N B^{r_i,s_i}$ when $r_i$, for all $i$, map to $0$ under an automorphism of the Dynkin diagram. Furthermore, we give a description of the Kirillov--Reshetikhin crystals $B^{r,1}$ using tableaux of a fixed height $k_r$ depending on $r$ in all affine types. Additionally, we are able to describe crystals $B^{r,s}$ using $k_r \times s$ shaped tableaux that are conjecturally the crystal basis for Kirillov--Reshetikhin modules for various nodes $r$.

description: This letter exposes a tight connection between the thermodynamic efficiency of information processing and predictive inference. A generalized lower bound on dissipation is derived for partially observable information engines which are allowed to use temperature differences. It is shown that the retention of irrelevant information limits efficiency. A data representation strategy is derived from optimizing a fundamental physical limit to information processing: minimizing the lower bound on dissipation leads to a data compression method that maximally retains relevant, predictive, information. In that sense, predictive inference emerges as the strategy that least precludes energy efficiency.

description: Dark matter may be discovered through its capture in stars and subsequent annihilation. It is usually assumed that dark matter is captured after a single scattering event in the star, however this assumption breaks down for heavy dark matter, which requires multiple collisions with the star to lose enough kinetic energy to become captured. We analytically compute how multiple scatters alter the capture rate of dark matter and identify the parameter space where the affect is largest. Using these results, we then show how multiscatter capture of dark matter on compact stars can be used to probe heavy ($m_X >$ TeV) dark matter with remarkably small dark matter-nucleon scattering cross-sections. As one example, it is demonstrated how measuring the temperature of old neutron stars in the Milky Way's center provides sensitivity to high mass dark matter with dark matter-nucleon scattering cross-sections smaller than the xenon direct detection neutrino floor.

description: The Oldest Evidence of Silver Processing in Europe. A Hoard from Košíky (Okr. Uherské Hradiště / CZ) In the Early Eneolithic (4300–3800 BC), Europe saw an increased occurrence of both isolated copper finds and hoards. Since recently, we can add to them a small hoard from Košíky (SE Moravia / CZ). The Košíky hoard is unique, because it contained a new type of artefact – a copper hammer with a narrowed grip and flat-hammered working surface instead of a cutting edge. The authors conducted a Scanning Electron Microscopy (SEM) analysis that proved the occurrence of silver flakes sticking to the hammer’s working surface. The study introduces not only a still unknown type of copper industry, but also the first evidence of the early use of silver hammering in Europe.

Challenging the incompatibility paradigm: a democratic audit of Jordan, 1990-2010
Creators: name: Hawwari, Adli
Publisher: name: University of Westminster
Year: 2012

description: This thesis assesses the state of democracy in Jordan over a period of twenty years (1990-2010), and revisits the claims of incompatibility between democracy and both Islam and Islamism. It subjects the claims to theoretical and empirical tests. This is possible through a case study of Jordan. The state was established by Britain, and is ruled by a dynasty, which highlights its lineage to the Prophet of Islam, Muhammad. Jordan also allowed the Muslim Brothers to take part in the process characterised by King Hussein in 1989 as the ‘resumption of our democratic life.’ Incompatibility is taken to mean that Islamic teachings prohibit adopting democracy as a system of government, as Qutb and Mawdudi have argued; and that democracy cannot take root in a Muslim society because the state and church (mosque) are inseparable, as argued by Lewis and others. The thesis outlines the procedure Muslim jurists use to declare an act or a notion to be allowed (halal) or forbidden (haram). It also engages with various democratic theories including the argument that democracy is ‘an essentially contested concept.’ The thesis establishes that, theoretically, Islam is not incompatible with democracy, whether as claimed by Qutb and Mawdudi, or Lewis and Huntington. Moreover, the thesis posits that if the democratic audit establishes that Jordan is a democracy, the compatibility of democracy and Islam is validated empirically. The audit revealed that Jordan was not a democracy. The roles of Islam and Islamism in hindering the development of democracy in Jordan were examined. The evidence indicated that they did not. Therefore, other reasons were examined, such as rentierism, Arab-Israel conflict, and Rustow’s modernisation theory. The latter offers the most plausible explanation, as Jordan has not satisfied Rustow’s four antecedents to democracy. The Islamist groups have not yet managed to be in power through democratic means. It remains debatable whether they will adhere to democracy after it brings them to power. The case of Jordan provides counter-evidence that the Islamists can hold the belief that Islam provides a superior form of government, but can simultaneously play by democratic rules. One could even argue that in Jordan there was a case of a democratic paradox in reverse.
Towards understanding two-level-systems in amorphous solids -- Insights from quantum circuits

description: Amorphous solids show surprisingly universal behaviour at low temperatures. The prevailing wisdom is that this can be explained by the existence of two-state defects within the material. The so-called standard tunneling model has become the established framework to explain these results, yet it still leaves the central question essentially unanswered -- what are these two-level defects? This question has recently taken on a new urgency with the rise of superconducting circuits in quantum computing, circuit quantum electrodynamics, magnetometry, electrometry and metrology. Superconducting circuits made from aluminium or niobium are fundamentally limited by losses due to two-level defects within the amorphous oxide layers encasing them. On the other hand, these circuits also provide a novel and effective method for studying the very defects which limit their operation. We can now go beyond ensemble measurements and probe individual defects -- observing the quantum nature of their dynamics and studying their formation, their behaviour as a function of applied field, strain, temperature and other properties. This article reviews the plethora of recent experimental results in this area and discusses the various theoretical models which have been used to describe the observations. In doing so, it summarises the current approaches to solving this fundamentally important problem in solid-state physics.

Management of the brain drain and its relationship withdemocratisation and human development in Libya
Creators: name: Gamaty, Giuma
Publisher: name: University of Westminster
Year: 2012

description: This thesis explores the brain drain and its relationship with democratisation and overall human development, including political development, using Libya as a case study. However, its implications are applicable to a wider region of developing countries, especially the Middle East and Africa. The research attempts to make a new contribution to understanding the brain drain phenomenon by empirically testing the possible link between the brain drain and socio-economic and political factors, including the lack of democracy, rule of law and human security. It also critically evaluates the contemporary theories of evaluation of human development based mainly on economical/educational indices, and highlights the limitations of the Human Development Index (HDI), as a measure of human development. A more holistic measure, based on the capability approach that incorporates a wide range of reflective indices including freedom, democratic values and human rights, is advocated. The research also argues in favour of a shift from the brain drain to a ‘brain circulation’ paradigm and from a single ‘return’ option to a possible ‘Diaspora’ option by which the contribution to their countries of origin, of those who have emigrated, need not be measured purely by their permanent return. Although the migration of highly skilled people – ‘human capital flight’ – cannot be physically prevented, the underlying ‘PUSH’ factors should be tackled. These include lack of freedom, human security, democracy, and lack of investment in both education and research and development. They also include better job rewards and conditions. Receiving countries, mainly OECD members, also have a moral responsibility not to create ‘PULL’ factors, such as the incentives of selective immigration policies to attract human capital from developing countries, where it belongs and is badly needed. The new era of globalisation and ICT makes it possible for ‘Diaspora Networks’ to facilitate the contribution of migrants to their source countries. Diaspora migrants with high human capital can engage with home countries and contribute towards developing a strategic vision for overall development. One vital area that Diaspora migrants can contribute to is ‘capacity building’, not just at the individual level but crucially at the institutional and societal level. Diaspora migrants, as ‘experts’ in their fields, can contribute to democratisation, as a transitional process towards democracy, which in turn is beneficial to enhancing human development because democratic countries have demonstrated higher human development than non-democratic ones. Human development, as an outcome, can therefore be an incentive for embarking on democratisation. A process of democratisation that leads to democracy will reduce some of the push factors causing the brain drain and its detrimental consequences.

Central - regional budget allocation process in Iran: a critical analysis
Creators: name: Firouzfar, Gholamhossein
Publisher: name: University of Westminster
Year: 2012

description: This doctoral thesis investigates the process and problems of central (top-down) budgeting system of Iran and aims at exploring how it can be replaced with a decentralized (Bottom –up) model that may be more in line with the interests and expectations of regions of the country. In chapter 1, the trend of socio-economic planning in last decades (particularly after the Islamic revolution) is studied and the reason why access to the endowment of fossilized energy resources could not accelerate and pass current developing situation is reviewed. Then in chapters 2 and 3 a historical pathology of planning and budgeting system considering various conceptual understandings of planning and budgeting and their underlying effects on development indicators is discussed. To highlight the importance of participatory role of people in process of planning and budgeting, the concepts and characteristics of good governance and its possibility to implement in Iran is critically reviewed in chapter 4. Differences in the conceptual understanding of decentralization has urged the author to resort to questionnaires and face to face interviews with most experienced experts and scholars in the field of planning and budgeting in Iran, which are explained in detail in chapter five. Based on the compilation and classification of viewpoints of the respondents and concentration on the concept of good governance, chapter 6 of the thesis entails reformative guidelines which are presented in line with necessary changes in the basic rules and regulations governing the budgeting system of the country and has provided practical steps towards its realization. This thesis contributes to an initiative document for the adoption of executive policies in Iran's planning and budgeting system which eventually results in the improvement of living conditions and the development indices of the country.
