System Innovation in Spatial Development: Current Dutch Approaches

A system innovation is a cross-organizational qualitative intervention that various system participants bring about together through their various contributions of different kinds of knowledge and skill. The term refers to the innovation of an entire system involving many actors. Spatial development refers to both the dynamic in land use, and changes in the development and implementation of spatial plans. The current large number of societal and spatial developments taken as a whole in a country such as the Netherlands increase the pressure on space and create the need for a powerful system innovation. This paper explains the system innovation which is going on in the Netherlands now, drawing on such themes as the coproduction of policy, public–private partnership and demand management. A process architecture for area development is more and more proposed, in which project envelopes are formed, the scope is optimized and surplus profits are ploughed back into the area (value capturing). The future will tell whether this new approach will really work and whether the traditional values and performance of Dutch spatial planning will be safeguarded under changing circumstances.     

Why protect civilians? Innocence,immunity and enmity in war

The issue of civilians in war has risen to new heights in international political consciousness in recent years. The principle of civilian protection has been at once the justification for war and the main guide to the conduct of such wars in Kosovo, Afghanistan ands most recently in Iraq. The so-called new wars of the 1990s have seen a consistent pattern of massive civilian atrocity and the new policies of massive global terrorism are similarly intent on civilian attack. It remains to be seen how well those pursuing the war against terror will hold to the civilian ethic. In truth, the idea of the civilian is a deeply contested one and has more usually been rejected than embraced by those who pursue war, political violence and terror. The simple power of the idea itself and the humanitarian sentiment that accompanies it to produce the notion of 'innocent civilians' cannot be relied upon to make a reality of civilian protection. Instead, the case for civilian identity and civilian protection must be determinedly and continuously argued in war. This means recognizing the main sources of political, passionate and practical objection to the civilian idea and taking them on one by one as they arise. Repeatedly arguing the case for civilian rights must be at the very heart of political, military, humanitarian and religious endeavour. Arguments of prudence and self-interest must be made alongside much deeper and more difficult moral arguments about people's innocence, their identity and their relationship to war. Holding fast to the civilian ethic in the face of terror and war requires significant moral argument and moral leadership from politicians, military commanders and ordinary people alike.

Effect of organic and inorganic consolidation agents on Tlaltecuhtli monolith

A huge monolithic piece corresponding to the first years of the sixteenth century has been discovered in Mexico City. It represents the earth goddess Tlaltecuhtli. The preservation of such a magnificent piece is imperative. Therefore, the surface has to be characterized and the interaction of consolidants with the rock has to be understood.Some of the consolidation methods are impregnation of the mineral with nopal or silicic acid derivatives. In this work we compare the physico-chemical effects of organic and inorganic consolidants. Original and impregnated samples are characterized with a series of original techniques: X-ray diffraction, nuclear magnetic resonance, nitrogen adsorption and small angle X-ray scattering. Fractal dimension, specific surface area and pore size distribution clearly differentiated the samples. The organic materials, nopal gum or slobber, cover the mineral particles with a smooth layer. The KSE solutions react and lead to microporosity.     

Mobility or migration: a case study from the Neolithic settlement of Nieder-Mörlen (Hessen,Germany)

A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.     

Simplified Macro-Model for Infill Masonry Panels

In structural analyses, masonry infill walls are commonly considered to be non structural elements. However, the response of reinforced concrete buildings to earthquake loads can be substantially affected by the influence of infill walls. In this article, an improved numerical model for the simulation of the behavior of masonry infill walls subjected to earthquake loads is proposed and analyzed. First, the proposed model is presented. This is an upgrading of the equivalent bi-diagonal compression strut model, commonly used for the nonlinear behavior of infill masonry panels subjected to cyclic loads. Second, the main results of the calibration analyses obtained with two series of experimental tests are presented and discussed: one on a single frame with one story and one bay tested at the LNEC Laboratory; and the second, on a full-scale four story and three-bay frame tested at the ELSA laboratory.     

Comparison of GIS‐Based Logic Scoring of Preference and Multicriteria Evaluation Methods: Urban Land Use Suitability

Multi‐criteria evaluation (MCE) methods are useful tools to evaluate the land suitability for various uses and assist in the effective management of available land. Many common GIS‐based MCE methods, such as analytical hierarchy process (AHP), ordered weighted averaging (OWA), and a combination of AHP and OWA methods (AHP–OWA) are not able to fully represent all the logic that constitute a wide range of human decision‐making reasoning. Consequently, improved GIS‐based MCE methods such as Logic Scoring of Preference (LSP) method are needed. The main objectives of this study are to: (1) implement the GIS‐based LSP method for land suitability evaluation and (2) compare qualitatively and quantitatively the suitability maps generated by LSP and three GIS‐based MCE methods. This study was implemented with data sets from Boulder County, Colorado, USA for the case study of the urban land suitability evaluation. The qualitative properties of MCE methods and the Receiver Operating Characteristic (ROC) statistics were used as comparison metrics. The results indicate that soft computing methods and particularly LSP performed the best among GIS‐based MCE methods for the urban land use application.     

Ductility-Equivalent Viscous Damping Relationships for Beam-to-Column Partial-Strength Steel Joints

This paper seeks to contribute to the development and improvement of displacement-based design procedures, proposing improved ductility-equivalent viscous damping relationships for steel moment-resisting framed structures with dissipative beam-to-column partial-strength joints. These relationships can be used directly in procedures like the Direct Displacement-Based Seismic Design (DDBD) that uses effective stiffness, ductility-equivalent viscous damping relationships, and period-displacement relationships in a performance-based design approach. To this end, a finite element model of a steel beam-to-column sub-assemblage, characterized by an extended end-plate, is developed in ABAQUS. The model, which is validated against monotonic and cyclic experimental data obtained in previous research, is employed to carry out non-linear time-history (NLTH) analyses, using real records scaled to target several levels of ductility demand. A procedure is then proposed and applied to determine the ductility-equivalent viscous damping relationships of the sub-assemblages. The equivalent linearization technique is applied to the non-linear responses obtained in the NLTH analyses, using an elastic single degree of freedom structure and the elastic displacement spectra. The influence of joints mechanisms and of the dynamic characteristics of the structure in the equivalent viscous damping is investigated, and an expression for ductility-equivalent viscous damping is proposed. The proposed expression represents a clear improvement in relation to the existing expressions available in literature.     

Importing and exporting spatial needs: A Dutch approach1

The increasing demand for space determines much of the approach to spatial planning in countries with a high population density like the Netherlands. In the next three decades more land will be needed for housing, work, traffic, leisure, nature and water. There is only one sector that will yield land: agriculture. The Dutch Minister of Spatial Planning has presented six intervention strategies to cope with the increasing demand for space: (1) priority setting; (2) export spatial needs; (3) reduce the need for space in accordance with policy; (4) intensify land use; (5) combine spatial needs; (6) transform spatial structures and buildings. Spatial planning in the Netherlands is becoming more and more geared to strategies 4, 5 and 6, which take the need for land as given. This paper seeks to explain that the first three strategies, and strategy 2 in particular, are also crucial for a country like the Netherlands, even though the policies associated with them would not generally be labelled spatial. For the spatial planner, however, the export of spatial needs is relevant as this determines the outcome of spatial planning to a large extent. This shall be illustrated by reporting on international residential migration, the use of leisure homes and second homes, international business migration and the restructuring of the agricultural sector. The Netherlands is not only exporting spatial needs, but also in the same time even imports needs at a larger scale, which puts spatial planning on a larger pressure. In the past the lack of space was solved by relinquishing land that was originally earmarked for water or nature. But the need for space for water and nature has increased recently and will continue to do so in the coming decades. This makes intervention strategy 2 even more relevant for the future. Spatial planners need to widen their horizons and include the import and export of spatial needs in their analyses.
