Few studies have investigated staying intentions and house attachment of residents who are confronted with physical damage to their dwelling in a risk area. This paper examines whether and how homeowners who are confronted with human-induced risks and the consequences of gas extraction in the Dutch Groningen rural earthquake region are attached to their damaged dwellings and why they stay. A content analysis was performed on 92 published interviews with homeowners of damaged dwellings. Additionally, three semi-structured interviews were held with key journalists and a homeowner. The results show that the homeowners’ staying intentions are interrelated with their house attachment; moreover, their awareness of their house attachment arises precisely because of the damage. We identify five subdimensions of physical and social house attachment, related to family history, heritage, (agricultural) business, personal refurbishment, and cohabiting family members, which make homeowners want to stay. The family history is especially mentioned by mid-to-later life homeowners, while some younger homeowners emphasize social house attachment to their children.We conclude that a homeowner's decision to stay in a damaged dwelling is a continuous cycle of reconsideration and renegotiation, punctuated by potential new risks and damages influencing the house attachment and staying intentions. Based on the found dimensions of house attachment, policymakers in risk areas could apply different approaches to homeowners in case of damage repair, rebuilding, or relocation plans, as homeowners - even those with damaged dwellings - may prefer to stay.

ABSTRACT: Local homebuyers in the Groningen earthquake regionIr. Hieke T. van der KloetHanze University of Applied Sciences GroningenResearch Centre for Built Environment NoorderRuimteh.t.van.der.kloet@pl.hanze.nl0031-50-595-2015The earthquakes after the natural gas extraction in the Groningen region of the Netherlands have a significant impact on the housing market and sustainability of the communities in this region. Since the strongest earthquake around the community of Huizinge in August 2012, with an magnitude of 3.6 on the Richter scale, it became clear there is a relation between natural gas extraction and earthquakes due to soil subsidence. As a consequence houses in the region get damaged and after research it gets obvious housing prices decline and the region will become unattractive to potential buyers of houses, damaged or not. Therefore the Dutch Petroleum Company (NAM) since April 29th 2014 offers a compensation for the loss of the housing price before and after the earthquake of Huizinge to property owners who want to sell their home. They only get the compensation after a sales deal and only if they agree with the proposed compensation. Since the compensation for the decrease in house prices has been introduced, the number of participants of the regulation is lacking behind the actual sales of houses. Our study aims to contribute to the research on the consequences of earthquakes by natural gas mining on the real estate market in the northern part of the Netherlands, especially the Groningen region. First of all we want to declare why relatively a large part of the property owners (about 60% until 2015) don’t request for the compensation regulation. Our second question concerns the buyers of the (damaged) houses in the earthquake area. Why would they buy a home in a region full of risks? Who are these buyers? We use a mixed-method approach for data collection which leads to an analysis of a unique dataset on notarial deeds of house sales in nine municipalities in the Groningen earthquake region according to The Land Registry of the Netherlands during the period 2013 until the end of 2015 as well as discovering common patterns of interview results with residents and experts. First results show that the majority of the homebuyers originate from the local earthquake area in the Province of Groningen. Reasons why property sellers after the house sale don’t opt for the compensation regulation concerns the complexity of the regulation, the used valuation model and the expected long control time afterwards.From the first results we conclude that the Groningen earthquake region still has its attractiveness for local residents and buyers. Otherwise the regulation for compensation doesn’t reach enough property sellers in the nine municipalities of the Groningen earthquake region. Advise to the Dutch government should be to generously compensate the residents of the Groningen earthquake regions for the loss of value of their dwellings, damaged or not. This will help to improve the regional development and attractiveness of areas that are effected by earthquakes.

This paper aims to quantify the evolution of damage in masonry walls under induced seismicity. A damage index equation, which is a function of the evolution of shear slippage and opening of the mortar joints, as well as of the drift ratio of masonry walls, was proposed herein. Initially, a dataset of experimental tests from in-plane quasi-static and cyclic tests on masonry walls was considered. The experimentally obtained crack patterns were investigated and their correlation with damage propagation was studied. Using a software based on the Distinct Element Method, a numerical model was developed and validated against full-scale experimental tests obtained from the literature. Wall panels representing common typologies of house façades of unreinforced masonry buildings in Northern Europe i.e. near the Groningen gas field in the Netherlands, were numerically investigated. The accumulated damage within the seismic response of the masonry walls was investigated by means of representative harmonic load excitations and an incremental dynamic analysis based on induced seismicity records from Groningen region. The ability of this index to capture different damage situations is demonstrated. The proposed methodology could also be applied to quantify damage and accumulation in masonry during strong earthquakes and aftershocks too.

Audience studies is not the vibrant field it was in its 1980s and early 1990s heyday. Cultural studies today has a more balanced interest in production, audiences and texts. A renewed focus in audience studies on everyday meaning production, identity and relations of power could benefit from recent developments. Theorization of power especially has benefited from recent work on governmentality. In accord with recent work on ‘affect’, there is an opportunity for renewed vitality and urgency. Was audience studies damaged beyond repair by the charge that it is a populist field that celebrates rather than interrogates everyday media culture? Could a concept such as cultural literacy provide a bridge to help re-establish the critical credibility of audience studies or would it burden this field with its implied notions of standards, distinction and cultural exclusion? The article discusses recent work with youth audiences to inquire into the possibilities of ‘critical literacy’. It proposes taking up questions and insights raised by affect theory, to merge appreciation, criticism and understanding of the forces that drive (the possibility of) change, and to embed critical literacy in cultural studies’ ongoing interest in the construction of (cultural) citizenship.

Groningen gas field is the largest on-land gas resource in the world and is beingexploited since 1963. There are damaging earthquakes, the largest of which was 3.6 magnitude. The recursive induced earthquakes are often blamed for triggering the structural damages in thousands of houses in the area. A damage claim procedure takes place after each significantly felt earthquake. The liability of the exploiting company is related to the damages and the engineering firms and experts are asked to correlate the claimed damages with a past earthquake. Structures in the region present high vulnerabilities to the lateral forces, soilproperties are quite unfavourable for seismic resistance, and structural damages are present even without earthquakes. This situation creates a dispute area where one can claim that most structures in the region were already damaged because of the fact that the soil is soft, the ground water table oscillates, and structures are vulnerable to external conditions anyhow and deteriorate in time, which can be the main cause of such structural damages. This ambiguity of damage vs earthquake correlation is one of the main sources of the public unrest in the area up until today. This study presents the perspective of people in the region in terms of liveability and the social acceptance of earthquakes in their lives. An attempt has been made to translate these social effects and expectations into structural performance metrics for ordinary houses in the region. A new seismic design and assessment approach, called Comfort Level Earthquake (CLE) has been proposed.

In Groningen, the Netherlands, induced earthquakes occur in a relatively densely populated area, the so-called Groningen gas field. Many houses and other buildings have been facing damage, from minor cracks to severe damage. The gas extraction company (NAM, a joint venture of Shell and Exxon Mobil) is held responsible for the earthquakes and has a legal liability to compensate for the damage. In addition to damage, several houses in the area are thought to be unsafe (not allowing occupants to leave their houses alive in case of a major earthquake). Both NAM and the Dutch government play a crucial role in the gas problems; where NAM is responsible for damage, the government has to guarantee citizens’ safety. Government has given orders to develop a strengthening operation for thousands houses.For many inhabitants, the practice of damage repair and strengthening has not been very effective and satisfying. First, the system of damage compensation, is neither simple nor expeditious; many citizens experience long waiting times, arbitrariness in causality and damage judgements and, as a result, unfair treatments. Second, after plans had been launched to inspect and eventually strengthen thousands of houses, the Minister decided to gradually reduce gas extraction. Immediately after that, he also decided to pause the intended strengthening operation, leaving many inhabitants in uncertainty about the current safety of their houses. In short, Groningen citizens don’t feel taken seriously by NAM, government and executing agencies, they are dissatisfied with damage settlements and their confidence in private (oil/gas companies) and public parties (government) has reached an all-time low. This situation has turned out to be very obstinate and difficult to turn. Our statement is that the architecture of the damage and strengthening operation is based on a systematic flaw. Although several minor changes have been made in the damage settlement and strengthening system, they have been limited to executing agencies and are not substantial. Therefore it is argued that, unless this structural flaw is being solved, the Netherlands will stay confronted with Groningen citizens whose trust in government is a far cry and will eventually lead to feelings of alienation.

In the Netherlands, there is an increasing need for collective forms of housing for older people. Such housing bridges the gap between the extremes of living in an institutionalised setting and remaining in their own house. The demand is related to the closure of many residential care homes and the need for social engagement with other residents. This study focuses on housing initiatives that offer innovative and alternative forms of independent living, which deviate from mainstream housing arrangements. It draws on recent literature on healthcare ‘rebels’ and further develops the concept of ‘rebellion’ in the context of housing. The main research question is how founders dealt with challenges of establishing and governing ‘rebellious’ innovative living arrangements for older people in the highly regulated context of housing and care in the Netherlands. Qualitative in-depth interviews with 17 founders (social entrepreneurs, directors and supervisory board members) were conducted. Founders encountered various obstacles that are often related to governmental and sectoral rules and regulations. Their stories demonstrate the opportunities and constraints of innovative entrepreneurship at the intersection of housing and care. The study concludes with the notion of ‘responsible rebellion’ and practical lessons about dealing with rules and regulations and creating supportive contexts.

From a circular standpoint it is interesting to reuse as much as possible construction and demolition waste (CDW) into new building projects. In most cases CDW will not be directly reusable and will need to be processed and stored first. In order to turn this into a successful business case CDW will need to be reused on a large scale. In this paper we present the concept of a centralized and coordinated location in the City of Utrecht where construction and demolition waste is collected, sorted, worked, stored for reuse, or shipped elsewhere for further processing in renewed materials. This has expected advantages for the amount of material reuse, financial advantages for firms and clients, generating employability in the logistics and processing of materials, optimizing the transport and distribution of materials through the city, and thus the reduction of emissions and congestion. In the paper we explore the local facility of a Circular Hub, and the potential effects on circular reuse, and other effects within the City of Utrecht.
