A Synthetic Approach To Regional Development Theories Part II

Tekeli, İlhan
In this section an attempt will be made to demonstrate how existing regional development theories, when grouped into six tynes, form easily expandable and flexible frameworks. In examining each of these types, first a narrower framework of basic relations for each theory will be defined and later , the means of developing this framework with additional proposals will be presented. The theoretical structure derived will then be criticized in compliance with the concepts developed in second section, and then in relation to the five-fold national spatial organization policies formulated in the first part of this paper. In this section regional development theories are re-arranged into six types as follows: a.l Stage Theories of Development a.2 Economic Base Theory a.3 Theories of the Production Function Type a.4 Shift Theory a.5 Growth Pole Theory (Perroux type) a.6 Polarized Development Theory (Friedmann type) The theories combined in these groups are extensions of national development theories, and thereby represent "soft approach theories" concentrating on how development could be initiated and accelerated. In extending these theories into a more flexible and dynamic structure, use is made of the following three types of process-theories: b.l Theories of Diffusion b.2 Migration Theories b.3 Theories on Spread Effect and Backwash Effect If regional development theories, in contrast to the theories of national development, are to concentrate on the spread of development rather than its initiation, then theories fundamentally concerned with development would fall into the latter group. Should a synthesis be attempted with the theories in these two groups, it would be possible to explain how growth occurs in a region (area) or a city (node), and how it spreads to its periphery, but the effect of this development on spatial organization would not be clearly included in the analysis. A third group of theories therefore, is included in order to establish the relation of development with spatial organization: c.l Central Place Theory c.2 Empirical generalizations such as the Rank-Size rule of settlements c.3 Macro-descriptions on national spatial organization In the following sections we shall study how the six theories given in the first group can be combined with those of the second and third groups to obtain larger synthetic theories.


A Methodology for Optimal Layout Design of Pressure Cells for Concrete Faced Rockfill Dams
Arı, Onur; Yanmaz, Ali Melih (Springer Science and Business Media LLC, 2018-08-01)
In this study, a methodology for optimal layout design of pressure cells for concrete faced rockfill dams is developed. A representative dimensionless stress distribution model was formed for obtaining the magnitudes and location of different stress zones as a function of dam height. This information enabled development of a procedure for proper location and the number of pressure cells throughout the dam body. A vertical placement algorithm based on error minimization was first developed, which is followed...
A methodology for reliability-based design of rock slopes
DUZGUN, HSB; Yücemen, Mehmet Semih; Karpuz, Celal (Springer Science and Business Media LLC, 2003-04-01)
A reliability-based methodology for the design of rock slopes, that can easily be implemented by the practicing engineers is proposed. The advanced first-order second-moment (AFOSM) method is adopted as the reliability assessment model and its application is illustrated for the case of plane failure. A model is developed within the framework of first-order second-moment approach to analyze the uncertainties underlying the in situ shear strength properties of rock discontinuities. Here, particular emphasis i...
An assume guarantee verification methodology for aspect oriented programming
Ispir, Mustafa; Betin Can, Aysu (2008-09-19)
We propose a modular verification methodology for aspect oriented programs. Aspects are the new modularization units to encapsulate crosscutting concerns and have powerful features whose effects can drastically change software behavior. Having such an impact on behavior requires an automated verification support. In this work we introduce a technique that separately answers two questions: "does the aspect have the provisioned effect?" and "does the base program satisfy the assumptions of the aspect?" To ans...
A robust time-cost-quality-energy-environment trade-off with resource-constrained in project management: A case study for a bridge construction project
Lotfi, Reza; Yadegari, Zahra; Hosseini, Seyed Hossein; Khameneh, Amir Hossein; Tirkolaee, Erfan Babaee; Weber, Gerhard Wilhelm (2022-01-01)
Sustainable development requires scheduling and implementation of projects by considering cost, environment, energy, and quality factors. Using a robust approach, this study investigates the time-cost-quality-energy-environment problem in executing projects and practically indicates its implementation capability in the form of a case study of a bridge construction project in Tehran, Iran. This study aims to take into account the sustainability pillars in scheduling projects and uncertainties in modeling the...
A novel modal superposition method with response dependent nonlinear modes for periodic vibration analysis of large MDOF nonlinear systems
Ferhatoglu, Erhan; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (Elsevier BV, 2020-01-01)
Design of complex mechanical structures requires to predict nonlinearities that affect the dynamic behavior considerably. However, finding the forced response of nonlinear structures is computationally expensive, especially for large ordered realistic finite element models. In this paper, a novel approach is proposed to reduce computational time significantly utilizing Response Dependent Nonlinear Mode (RDNM) concept in determining the steady state periodic response of nonlinear structures. The method is ap...
