Abstract (sommario):

This research is a small part of a bigger field of research made before by other authorsregarding the humans in the urban public space. It has a small context compared to otherstudies, but a big impact inside the community. It aims at finding answers to questions thatother researchers asked before, but under different circumstances and they displayed them through different ways such as documentary films (The social life of small urban spaces 1980, How to live in a city 1964).After experiencing the city life of Malmö and some questions have been raised, the concept of resilience intersected with the interest of social public life in a neighbourhood. In order to have the theoretical framework to answer the research question, the thesis follows a literature review, where the concepts of resilience, urban resilience, resilient urban design and social resilience have been explored.Next, after exploring the city of Malmö, some case studies have been chosen and studiedthrough direct observation in different months starting with March and various times of theday. In the methodological approach section the methods are explained as well as a detailed presentation of the biggest tool used for this research: observational drawing. The tools used for the observation are field notes, observational drawings and photographs. The cases are spread throughout the city and are located in neighbourhoods with different urban tissues. The results reveal all the observational drawings made during the field visits and the field notes written. They show how people use the spaces in all three case studies depending on the weather or other external factors.The discussion reveals the complexity of the relation between concepts and the empiricaldata, following the initial aim of the research throughout the discussion. This thesiscontributes with important outcomes to the field of urban studies creating awareness about the urban context and its influence on people. The findings of this study show a diversity and creativity of users in using the public space.

Abstract (sommario):

Syftet med denna kvalitativa studie är att genom enkäter undersöka om det finns en diskrepans mellan det teoretiska begreppet resiliens och den empiriska tillämpningen. För att besvara denna fråga undersöks följande delfrågor: Vad ingår i olika teoretiska resiliensbegrepp? Hur ser innebörden av resiliensbegreppet ut hos svenska krishanteringsaktörer idag? Hur arbetar svenska krishanteringsaktörer för resiliens för att göra städer säkrare i framtiden? Denna studie ska vara till hjälp för krishanteringsaktörer i deras förståelse för vad resiliensbegreppet är och finna kunskap i dessa tre resilienskoncept för att kunna använda det i sitt praktiska arbete när de talar om att arbeta för resiliens. I denna studie har tjugosex stycken enkäter skickats ut till personer som på något sätt arbetar med krishantering. Respondenterna arbetar på olika nivåer (kommun, länsstyrelse, myndighet, privat sektor samt forskare). Forskning och teorier kring resiliens kommer baseras på Brian Walker & David Salt som beskriver ingenjörsteknisk resiliens och ekologisk resiliens i boken Resilience thinking därefter förklarar Ulrich Beck enligt boken Risksamhället hur man måste arbeta för framtiden och inte se bakåt för att planera efter det som skett i dåtid. Pickett, McGrath, Cadenasso & Felson beskriver i sin forskning Ecological resilience and Resilient cities hur hållbarhet är en viktig del i resiliens. Avslutningsvis beskrivs det tredje resiliensbegreppet, nämligen Socio-ekologisk resiliens där Carl Folke lyfter upp vikten av att utveckla resiliens för det socio-ekologiska systemet för att skapa en anpassningsförmåga som möjliggör kontinuerlig utveckling, som ett dynamisk adaptiv samspel mellan att upprätthålla och utvecklas i förändring. För att kunna minska diskrepansen mellan begreppet resiliens och den empiriska tillämpningen krävs att det först och främst finns en förståelse för och en kunskap om begreppet resiliens. Därefter krävs det en samverkan mellan olika aktörer speciellt att krishanteringsaktörerna tar del av de forskningsresultat som framkommer för att kunna implementera det praktiskt och på så sätt få nya innovativa idéer att arbeta efter.
The purpose of this qualitative study is through survey investigate if there is a discrepancy between the theoretical concept of resilience and the empirical application. To answer this question this study examines the following issues: What is included in various theoretical resilience concept? What is the meaning of the resilience concept at the Swedish crisis management actors today? How does the Swedish crisis management actors use resilience to make cities safer in the future? This study will be helpful for crisis management actors in their understanding of what the resilience concept and find the knowledge of these three concepts to use it in their practical work when they talk about working for resilience. In this study, twenty-six questionnaires was sent out to people who in some way are involved in crisis management. The respondents in this study work at different levels (municipal, county government, government, private sector and researchers). Research and theories of resilience is based on Brian Walker and David Salt describing engineering technical resilience and ecological resilience in the book Resilience thinking then Ulrich Beck explains according to the book Risk Society how one must work for the future and not look backwards and plan because of what was happening in the past. Pickett, McGrath, Cadenasso & Felson describes his research Ecological Resilience and Resilient Cities how sustainability is an important aspect of resilience. Finally the third concept is described, namely socio-ecological resilience where Carl Folke lifts the importance of developing resilience for the socio-ecological system to create an adaptability that allows for continuous development, a dynamic adaptive interaction between maintaining and developing in change. In order to reduce the discrepancy between the concept of resilience and the empirical application it requires, first and foremost an understanding and a knowledge of the concept of resilience. Then it requires a collaboration between various stakeholders especially the crisis management actors to take part of the research evidence and have a will to implement it practically and as a result get new innovative ideas to work with.

Teacher Resilience in Central Virginia: How Veteran Teachers become Resilient Lee Brantley Shields ABSTRACT The development of teacher resilience is important in improving teacher retention. This study identified reasons veteran teachers have remained in the classroom; individual and contextual factors of resilience; significant challenges the teachers have encountered; and strategies the teachers used for dealing with the challenging situations. This was a qualitative study that included interviews with 15 teachers in a rural school division in Central Virginia. Data analysis occurred through deductive coding of the transcribed interviews using qualitative data analysis software. The findings for this study identified seven factors that veteran teachers indicated were important in their decision to remain in the classroom. The study also identified 22 individual factors of resilience and 10 contextual factors presented through the experiences of the veteran teachers. The veteran teachers described four challenges that they have faced in their school division and the strategies they used to overcome those challenges. The study concludes with the discussion, implication, and conclusion of the findings.

Abstract (sommario):

This thesis introduces a new dimension over which systems dependability may be evaluated, exhaustion-safety. Exhaustion-safety means safety against resource exhaustion, and its concrete semantics in a given system depends on the type of resource being considered. The thesis focuses on the nodes of a fault-tolerant distributed system as crucial resources and on understanding the conditions in which the typical assumption on the maximum number of node failures may or may not be violated. An interesting first finding was that it is impossible to build a {node-exhaustion-safe intrusion-tolerant distributed system under the asynchronous model. This result motivated the research on developing the right model and architecture to guarantee node-exhaustion-safety. The main outcome of this research was proactive resilience, a new paradigm to build intrusion-tolerant distributed systems. Proactive resilience is based on architectural hybridization and hybrid distributed system modeling: the system is asynchronous in its most part and it resorts to a synchronous subsystem to periodically recover the nodes and remove the effects of faults/attacks. The Proactive Resilience Model (PRM) is presented and shown to be a way of building node-exhaustion-safe intrusion-tolerant distributed systems. Finally, the thesis presents two application scenarios of proactive resilience. First, a proof-of-concept prototype of a secret sharing system built according to the PRM is described and shown to be highly resilient under different attack scenarios. Then, a novel intrusion-tolerant state machine replication architecture (based on the PRM) is presented and a new result established, that a minimum of 3f+2k+1 replicas are required to ensure availability, on a system where f arbitrary faults may happen between recoveries, with at most k replicas recovering simultaneously

Abstract (sommario):

Although most researchers agree that resilience is defined as the extent to which an individual bounces back and recovers from stress and adversity, the field has not yet settled on the underlying structure of the resilience construct; its lower-order factors remain in dispute and undefined. In this study, five of the most prominent resilience measures (i.e., Ego Resilience, Block & Kremen, 1996; The Resilience Scale, Wagnild & Young, 1993; The Connor-Davidson Resilience Scale, Connor & Davidson, 2003; The Resilience Scale for Adults, Friborg, Hjemdal, Rosenvinge, & Martinussen, 2003; The Brief Resilience Scale, Smith, Dalen, Wiggins, & Tooley, 2008) were administered to two large samples of U.S. adults (N = 396 and 336, respectively). Through a combination of exploratory and confirmatory techniques, seven lower-order resilience factors were identified. Relationships between general resilience, lower-order resilience factors, and correlates were examined. Results reveal that lower-order resilience factors are moderately correlated with one another and are differentially related to outcomes of interest. Follow-up hierarchical regression and relative weights analyses further reveal that general resilience substantially overlaps with Big Five personality measures, but, in many cases, its lower-order factors do not. Consequently, it is recommended moving forward that researchers continue to study the resilience construct, but do so by focusing on lower-order resilience factors, rather than on global measures of the overall resilience construct.

Abstract (sommario):

The balance between family support and child protection services is continuously challenged by high-profile cases. These highlight shortcomings both of the UK system and of research on the effectiveness of child maltreatment interventions (Munro, 2011). One such intervention is the Resolutions Approach to ‘denied’ child abuse (Turnell and Essex, 2006) – a systemic approach which creates a support network including extended family, friends, community members and professionals. There is, however, only limited research analysing the supporters’ experience of this intervention. In the present study five semi-structured group interviews were conducted in order to investigate how the family support network members made sense of their participation in Resolutions. Through a thematic analysis three related themes: returning hope; building safety and trusting a professional were identified. Additionally, special attention was paid to processes linked to the creation of family resilience (Walsh, 2003). Based on two contrasting case studies the potential creation of family resilience through Resolutions was discussed and clinical recommendations for creating family resilience within support networks were outlined.

Abstract (sommario):

Software has, for better or worse, become a core component in the structured management and manipulation of vast quantitates of information, and is therefore central to many crucial services and infrastructures. However, hidden among the various benefits that the inclusion of software may bring is the potential of unwanted and unforeseen interactions, ranging from mere annoyances all the way up to full-blown catastrophes. Overcoming adversities of this nature is a challenge shared with other engineering ventures, and there are many developed strategies that work towards eliminating various kinds of disturbances, assuming that it is possible to apply such strategies correctly. One approach in this regard, is to accept some anomalous behaviors as mere facts of life and make sure that the situations experienced are dealt with in an expeditious manner, while at the same time trying to discover, implement and improve safe-guards that can lessen adverse consequences in the event of future problems; in short, to embed resilience. The work described in this thesis explores the foundations of software resilience, and thus covers the main resilience-enabling mechanisms, along with supporting tools, techniques and methods used to embed resilience. These instruments are dissected and analyzed from the perspective of stakeholders that have to operate on pre-existing, critical, large and heterogeneous subjects that are to some extent already up and running at the point of instrumentation. Finally, in the course of describing this subject, the thesis describes a demonstrator environment for self-healing activities in a partially damaged power grid, its construction details and the initial results of the study conducted in this environment.

Abstract (sommario):

De grandes transformations écologiques et climatiques sont aujourd'hui à l’œuvre. Elles sont sources d’instabilité environnementale, à l’image d’évènements climatiques extrêmes devenus plus fréquents, plus intenses, et touchant de nouvelles régions du globe. A défaut de pouvoir empêcher ces changements, comment les sociétés humaines pourraient-elles s'y adapter ? Pour beaucoup de chercheurs et de décideurs, c’est par la résilience qu’elles y parviendront. Ce concept semble renfermer des solutions nouvelles, adaptées à un monde turbulent et incertain. Par définition, les systèmes résilients sont capables de rebondir face à des chocs inattendus, d’apprendre rapidement et de s'adapter à des conditions inédites. Malgré l’intérêt suscité par cette notion, les processus qui permettent à une société d’être résiliente restent encore mal connus. Cette thèse développe un cadre conceptuel nouveau permettant, via la modélisation mathématique, d'explorer les liens théoriques entre mécanismes économiques et résilience. Ce cadre repose sur une analyse critique de la résilience en écologie — domaine d’origine du concept — et en économie — notre champ d’application. Nous l’appliquons aux systèmes de production économique, modélisés comme des réseaux de firmes et analysés à travers la théorie des systèmes dynamiques. Cette thèse évalue l’aptitude de tels modèles, dits multi-agents, à générer des profils de bifurcations, étape incontournable de l’analyse mathématique de la résilience. Nous étudions pour cela une dynamique proie–prédateur très générale en écologie et en économie. Ensuite, cette thèse s'attaque à un facteur majeur qui entrave la résilience : les fortes interdépendances entre activités économiques, par lesquelles les retards et interruptions de production se propagent d’une entreprise à l’autre. En utilisant des réseaux de production réalistes, nous montrons comment les délais d'approvisionnement, lorsque intégrés dans des topologies particulières, démultiplient ces phénomènes de propagation. Ensuite, grâce à un modèle évolutionnaire, nous mettons en lumière l’existence d’un risque systémique : les cascades d’incidents ont lieu alors même que tous les agents possèdent des inventaires adaptés au niveau de risque. Ce phénomène s’amplifie lorsque les chaînes d'approvisionnement se spécialisent et se fragmentent. Ces résultats théoriques ont une valeur générale, et pourront servir à orienter de futures recherches empiriques. Cette thèse fait en outre avancer les connaissances sur des méthodes et objets mathématiques très récents, comme les équations booléennes à retard formant un réseau complexe, et les dynamiques évolutionnaires sur les graphes. Les modèles et le cadre conceptuel proposés ouvrent de nouvelles perspectives de recherche sur la résilience, en particulier sur l’impact des rétroactions environnementales sur l'évolution structurelle des réseaux de production
A wide range of climatic and ecological changes are unfolding around us. These changes notably manifest themselves through an increased environmental variability, such as shifts in the frequency, intensity, and spatial distribution of weather-related extreme events. If human societies cannot mitigate these transformations, to which conditions should they adapt? To many researchers and stakeholders, the answer is resilience. This concept seems to subsume a variety of solutions for dealing with a turbulent and uncertain world. Resilient systems bounce back after unexpected events, learn novel conditions and adapt to them. Theoretical models, however, to explore the links between socioeconomic mechanisms and resilience are still in their infancy. To advance such models, the present dissertation proposes a novel conceptual framework. This framework relies on an interdisciplinary and critical review of ecological and economic studies, and it is based on the theory of dynamical systems and on the paradigm of complex adaptive systems. We identify agent-based models as crucial for socioeconomic modeling. To assess their applicability to the study of resilience, we test at first whether such models can reproduce the bifurcation patterns of predator–prey interactions, which are a very important factor in both ecological and economic systems. The dissertation then tackles one of the main challenges for the design of resilient economic system: the large interconnectedness of production processes, whereby disruption may propagate and amplify. We next investigate the role of delays in production and supply on realistic economic networks, and show that the interplay between time delays and topology may greatly affect a network’s resilience. Finally, we investigate a model that encompasses adaptive responses of agents to shocks, and describes how disruptions propagate even though all firms do their best to mitigate risks. In particular, systemic amplification gets more pronounced when supply chains are fragmented. These theoretical findings are fairly general in character and may thus help the design of novel empirical studies. Through the application of several recent ideas and methods, this dissertation advances knowledge on innovative mathematical objects, such as Boolean delay equations on complex networks and evolutionary dynamics on graphs. Finally, the conceptual models herein open wide perspectives for further theoretical research on economic resilience, especially the study of environmental feedbacks and their impacts on the structural evolution of production networks

Master of Landscape Architecture
Department of Landscape Architecture/Regional and Community Planning
Blake Belanger
Resilience in social-ecological systems, defined by ecologist C.S. Holling (1973), is the persistence of systems after a disturbance. This theory of resilience is becoming increasingly important, especially in urban areas where human systems dominate. Therefore, creating resilient social-ecological systems is emerging as a focus for many landscape architects when designing urban landscapes. Researchers and practitioners have created frameworks and strategies for applying resilience theory, but designers are still lacking tangible methods they can use to implement design strategies to create resilient landscapes. This research presents a set of resilient design strategies, so landscape architects can have a tool to design generally resilient social-ecological systems in urban areas. In order to discover strategies which improve system resilience, I conducted a literature review and created a perceptual model of the social-ecological systems operating in the study site, Washington Square Park in Kansas City, Missouri. The perceptual model determined systems and system components I focused on in this research. These systems are soil, water, vegetation, fauna, and people. Strategies suggested by Jack Ahern (2011), Brian Walker and David Salt (2006), and Kevin Cunningham (2013) for creating resilience determined strategies which were applied to the system components in order to evaluate the park for resilience. The strategies suggested are modularity, redundancy, tight feedbacks, and ecosystem services. In addition, the system components and strategies were used to analyze case studies. I used strategies discovered in the case study analyses along with goals for the redesign of Washington Square Park, discovered by analyzing the site and previous park documents, to create the guidelines. I then used the guidelines to create a design proposal for the park. The current state of the system components in the park and the proposed state from the redesign were used to show the guidelines’ success in increasing the general resilience of Washington Square Park. These guidelines have potential to increase resilience in other urban civic spaces through a similar methodology I used for Washington Square Park. In addition, the guidelines have the potential to further research in applying resilience theory to the design of landscapes.

Abstract (sommario):

O atual sucesso da Internet vem inibindo a disseminação de novas arquiteturas e protocolos de rede. Especificamente, qualquer modificação no núcleo da rede requer comum acordo entre diversas partes. Face a isso, a Virtualização de Redes vem sendo proposta como um atributo diversificador para a Internet. Tal paradigma promove o desenvolvimento de novas arquiteturas e protocolos por meio da criação de múltiplas redes virtuais sobrepostas em um mesmo substrato físico. Adicionalmente, aplicações executando sobre uma mesma rede física podem ser isoladas mutuamente, propiciando a independência funcional entre as mesmas. Uma de suas mais promissoras vantagens é a capacidade de limitar o escopo de ataques, através da organização de uma infraestrutura em múltiplas redes virtuais, isolando o tráfego das mesmas e impedindo interferências. Contudo, roteadores e enlaces virtuais permanecem vulneráveis a ataques e falhas na rede física subjacente. Particularmente, caso determinado enlace do substrato seja comprometido, todos os enlaces virtuais sobrepostos (ou seja, alocados neste) serão afetados. Para lidar com esse problema, a literatura propõe dois tipos de estratégias: as que reservam recursos adicionais do substrato como sobressalentes, protegendo contra disrupções; e as que utilizam migração em tempo real para realocar recursos virtuais comprometidos. Ambas estratégias acarretam compromissos: o uso de recursos sobressalentes tende a tornar-se custoso ao provedor de infraestrutura, enquanto a migração de recursos demanda um período de convergência e pode deixar as redes virtuais inoperantes durante o mesmo. Esta dissertação apresenta ORE (Opportunistic Resilience Embedding – Mapeamento com Resiliência Oportunística), uma nova abordagem de mapeamento de redes para proteger enlaces virtuais contra disrupções no substrato físico. ORE é composto por duas estratégias: uma proativa, na qual enlaces virtuais são alocados em múltiplos caminhos para mitigar o impacto de uma disrupção; e uma reativa, a qual tenta recuperar, parcial ou integralmente, a capacidade perdida nos enlaces virtuais afetados. Ambas são modeladas como problemas de otimização. Ademais, como o mapeamento de redes virtuais é NP-Difícil, ORE faz uso de uma meta-heurística baseada em Simulated Annealing para resolver o problema de forma eficiente. Resultados numéricos mostram que ORE pode prover resiliência a disrupções por um custo mais baixo.
Recently, the Internet’s success has prevented the dissemination of novel networking architectures and protocols. Specifically, any modification to the core of the network requires agreement among many different parties. To address this situation, Network Virtualization has been proposed as a diversifying attribute for the Internet. This paradigm promotes the development of new architectures and protocols by enabling the creation of multiple virtual networks on top of a same physical substrate. In addition, applications running over the same physical network can be isolated from each other, thus allowing them to coexist independently. One of the main advantages of this paradigm is the use of isolation to limit the scope of attacks. This can be achieved by creating different, isolated virtual networks for each task, so traffic from one virtual network does not interfere with the others. However, routers and links are still vulnerable to attacks and failures on the underlying network. Particularly, should a physical link be compromised, all embedded virtual links will be affected. Previous work tackled this problem with two main strategies: using backup resources to protect against disruptions; or live migration to relocate a compromised virtual resource. Both strategies have drawbacks: backup resources tend to be expensive for the infrastructure provider, while live migration may leave virtual networks inoperable during the recovery period. This dissertation presents ORE (Opportunistic Resilience Embedding), a novel embedding approach for protecting virtual links against substrate network disruptions. ORE’s design is two-folded: while a proactive strategy embeds virtual links into multiple substrate paths in order to mitigate the initial impact of a disruption, a reactive one attempts to recover any capacity affected by an underlying disruption. Both strategies are modeled as optimization problems. Additionally, since the embedding problem is NP-Hard, ORE uses a Simulated Annealing-based meta-heuristic to solve it efficiently. Numerical results show that ORE can provide resilience to disruptions at a lower cost.

Tillvägagångssätt från ”Resilience Engineering” kan användas när säkerhetsstrategier utvecklas, men erfarenheten av detta är begränsad inom sjukvården. Masterarbetet genomfördes för att utforska hur ett förbättringsarbete kring att utveckla och använda instrumentet ”Resilient Assessment Grid”, RAG, kunde stödja medarbetarnas förutsättningar att arbeta på ett resilient sätt. Förbättringsarbetet genomfördes enligt Nolans förbättringsmodell. Studien var en fallstudie med kvalitativ ansats på en vårdavdelning inom specialiserad barnsjukvård. Studieresultatet visade att arbetet med att utveckla och använda RAG kunde stödja medarbetarnas förutsättningar att arbeta på ett resilient sätt genom att de fick tillgång till ett sätt att mäta förutsättningar för resiliens och genomföra strategiska förbättringsinterventioner. Medvetenheten och kunskapen om patientsäkerhet och resiliens ökade, vilket har lett till en ökad förståelse för verksamheten, och för vad som är viktigt för god patientsäkerhet. Vi har hittills inte kunnat påvisa förbättrade förutsättningar för resiliens genom att använda instrumentet RAG. Innan längre tid förflutit och ytterligare RAG-mätningar gjorts kan vi varken påvisa eller utesluta att förutsättningarna kommer förbättras. Erfarenheterna från masterarbetet kan nyttjas i kommande initiativ, inom komplexa adaptiva system i hälso- och sjukvården, som syftar till att förbättra förutsättningarna för resiliens.
This master´s thesis explores how an improvement work of developing and using the “Resilience Assessment Grid”, RAG, can support the potential for resilient performance on a paediatric ward, in light of the need for new safety strategies developed for complex adaptive systems. A qualitative case study of the improvement work was conducted. The improvement work was done according to the Model for Improvement. The work of developing and using RAG for measuring and managing resilient performance, supported the employees' potential for resilient performance by helping them in implementing strategic improvement interventions. The awareness and knowledge of patient safety and resilience increased, which led to increased understanding of the system and the needs of the system in terms of patient safety. We have not been able to show that the potential for resilient performance has improved by using RAG for measurement. We can neither demonstrate nor exclude that the potential will improve before further measurements have been made. Experience from the present study can be used in future interventions of improving the potential for resilient performance and patient safety in a complex adaptive system in the health care setting.

Abstract (sommario):

One in 4 children in the United States lives in a family impacted by the chronic, heritable disease of substance use disorder (SUD), also known as alcoholism or addiction. Recent research has demonstrated that resilience is a key protective factor against developing the disease in adolescence and adulthood and that the neurological roots of resilience lie in the child's experiences in early childhood. In spite of this, few resources related to family SUD or current models of resilience are included in preservice teacher preparation for early childhood educators. This study examined whether key components of Masten's model of resilience are found in fairytales, a form of literature commonly used in early childhood teacher preparation programs. A qualitative, descriptive, deductive content analysis was conducted on 24 fairytales from 22 different cultures, using a tool derived from Propp's morphology of fairytales and Masten's model of resilience. Results indicated that the texts of 96% of these stories contained multiple specific references to the 3 dominant evidence-based factors for resilience: attachment/relationships, initiative, and self-regulation. When broken into the 7 subcategories of these 3 protective factors, as identified by Masten, 9 fairytales contained examples of all 7 protective factors; 9 had examples of 6, and another 5 had examples of 5. The results of this study may be used to provide teacher educators with resources to better prepare preservice early childhood teachers to understand and nurture resilience in children, while addressing existing mandated learning objectives related to emergent literacy. This will benefit all children the teachers will work with, but especially those who are impacted by SUD and other forms of trauma.

Abstract (sommario):

Severe recovery deficits after post-disaster interventions have become the landscape seen globally. Humanitarian operations have struggled to find coherence between relief and recovery activities, which has resulted in a perceived operational gap between relief, recovery and development. This current dynamic has caused significant deficiencies within humanitarian programming, such as weak strategy, a lack of transition mechanisms, exit plans and effective recovery. A situation that stems from the current paradigm the humanitarian system operates under and the framework that has evolved around it. Supporting the development of adaptive resilience of a disaster-affected population, within the humanitarian sphere, has been theoretically posed to be fundamental for recovery; a programmatic consideration that could ensure former weak resilience would not hinder post-disaster recovery. Therefore, could a resilience building approach offer much needed solutions to the challenge of recovery within post-disaster contexts? This research aimed to understand whether resilience building within post-disaster environments could increase potential recovery of disaster affected populations and whether it is feasible to build individual/household (HH) level resilience through emergency response operations? The research looked specifically at adaptive resilience at the individual/HH level, clarifying the concept and understanding its modality in order to operationalise it within humanitarian programming. The common barriers to recovery experienced by individuals/HH in a crisis event were gauged, and the relationship between adaptive resilience and recovery determined. A unique singular case study was used to collect quantitative and qualitative data required to answer the key objectives of this research. The case study chosen was the 2010 Haiti earthquake response. Primary data was collected over a 7 months period through 37 semi-structured interviews and 31 online questionnaires with donors, government, INGOs, LNGOs and the private sector, that were operating within the Haiti response, and 18 disaster affected community members within a community discussion forum. Bringing a total participation of 86 individuals and organisations. An in-depth case study was developed in order to offer an evidence base for the proposed theory, that supporting adaptive resilience through emergency response programming has the ability to stimulate recovery. A new data collection tool was trialed within the community discussion forum, namely the Sociogram. This tool looked to assess the main components of adaptive resilience. Methodological rigour was introduced through the use of methodological and data triangulation to ensure validity and reliability of the research. The research successfully identified the main barriers to recovery, pinpointed the key components for adaptive resilience and the influence of emergency programming on the development of adaptive resilience, establishing the relationship between them. The role emergency response operations can play in the development of adaptive resilience was then explored. It has been demonstrated that to ensure recovery and allow for a more resilient society to evolve, adaptive resilience needs to be and can be supported and developed within emergency response operations. The research has been able to demonstrate, through the analysis of the Shelter and WASH response undertaken in Haiti, that developing resilience in the post-disaster environment is possible and an approach that is able to improve strategy within emergency response operations. Improvements would be seen in the provision of essential services within the response, a substantial increase in transitional and exit options and an increased capacity to proactively stimulate rapid recovery. This strategic approach to emergency response programming has the ability to offer the coherence needed between relief, recovery and development. Determining that a resilience building approach within emergency response operations could be the missing link or resolution to the perceived operational gap between relief, recovery and development. Pursuing a resilience building approach has the potential to bring much needed cultural change within the humanitarian sector that will shape operations for a more strategic and successful future.

Abstract (sommario):

Families raising autistic children grapple with stressors created by the child's often-unpredictable course of development that affects resilient family function. To that end, this study used a quantitative, non-experimental study design with 103 married parents (103 fathers, 103 mothers) raising autistic children to identify relationships between stress, father's resilience, mother's resilience, and family resilience employing the Baron and Kenny mediation regression technique. Consistent with family resilience theory, the study results demonstrated that families raising autistic children follow a resilient model. The study results suggest that father's resilience is positively related to family resilience (R² = .753,p < .001) and mother's resilience is positively related to family resilience (R² = .602, p < .001). Likewise, the study results further suggest that as parental stress increases, both father's resilience decreases (R² = .041,p = .040) and mother's resilience decreases (R² = .168, p < .001). Equally, the study results suggest that increased stress is linked to decreased family resilience (R² = .191, p < .001). However, stress does not fully mediate the relationship between father's resilience and family resilience (R = .887, R² = .787, F (2, 100) = 184. 707,p < .001), or between mother's resilience and family resilience (mother R = .777, R² = .604, F (2, 100) = 76.182,p < .001). Further, when investigating stress mediation in the combined father and mother resilience and family resilience relationship, stress still did not fully mediate the relationship (R = .623, R² = 389, F (2, 100) = 31.795,p < .001). This means that stress partly explains the relationship between parent resilience and family resilience, but not entirely. Implications are that parent resilience is correlated with family resilience, even after taking into account how stressed parents feel. Thus, despite being in a stressful situation, the more resilient parents are, the more resilient the entire family unit will be. Therefore, since a parent's resilience and the overall family reliance are strongly positively correlated when accounting for stress levels, the results of the present study suggest that parental resilience be considered when examining family resilience.

Abstract (sommario):

Previous studies of resistance in the field of sociology have focused on many types of resistance but have not examined poor women’s resistance in the aftermath of trauma. Psychologists have examined trauma recovery and resilience, but have not examined these topics from an integrated, sociological perspective. In this work, I synthesize current scholarship on resistance from sociology with resilience in psychology and address these existing gaps. Through open-ended, semi-structured interviews with twenty-three women who suffered traumatic life events, I answer the following questions: How do women narrate their rebound from trauma and how do they define those experiences? What are the commonalities in women's narratives of overcoming? How do race, class, sexuality, and poverty intersect to affect resistance and resilience for these women? What themes emerge in women’s discussions of overcoming trauma? What aspects of their trauma recovery involve resistance and resilience? My findings show that women trauma survivors are resilient and resistant in a number of ways: through understood therapeutic means including self-help, support groups, therapy, reading about and watching programs regarding the subject, discussing trauma and recovery with family and friends, using mentors, engaging in positive spirituality, and through creative expression. I found women were resistant in less traditionally understood ways. These include choosing to get help with coping from therapy or support groups against the wishes of loved ones or others due to stigma. Other methods included renaming themselves “survivor”, “thriver”, or reject labels entirely, and creating new, resilient selves. Finally, I found that survivors of traumatic life events often rejected community norms regarding how gender is “done,” by rejecting femininity, eschewing marriage, living as out lesbians, or choosing not to have children. Two unique findings emerged through the data collection. The first was that women from lower socioeconomic backgrounds frequently rejected the idea of victimhood, identified as survivors, or chose no label at all. They narrated their transition from victim to survivor as a sudden choice as opposed to, as the literature suggests, a process. Second, I find that there is a very particular script for coping in women from lower classes which frames traumatic life experiences as, “just part of being a woman.” I find that these frequently women employed a “tough guise” identity to reclaim respect in their low-income communities. I further find that women recreate new, socially valorized identities free from stigma by engaging in prosocial coping.

Abstract (sommario):

The focus of this thesis is to investigate resilience at an organisational level. The research aims to identify and establish the features of resilience within the response of an organisation to disruptive and crisis events. Natural disasters, pandemic disease, terrorist attacks, economic recession, equipment failure and human error can all pose both a potentially unpredictable and severe threat to the continuity of an organisation's operations. As a result, disruptive events highlight the need to develop robust and resilient organisational and infrastructural systems capable of adapting and overcoming complex disruptive events.

Abstract (sommario):

Remarried families are no longer the exception in society. Statistics reveal that this type of family structure is increasing. The need for family resilience research in varying family forms has been highlighted. Given the distinctive structure of the remarried family, there are specific dilemmas and challenges that need to be resolved on the journey towards family integration. Despite these challenges, many families benefit from their new family structure and show marked resiliency and ability to adapt. South African family resilience research is scarce. This study aimed to identify, explore and describe the resiliency factors that enable families to adjust and adapt as a result of being a stepfamily. The Resiliency Model of Family Stress, Adjustment and Adaptation (McCubbin, Thompson, & McCubbin, 2001) was used to conceptualize level of adaptation. Participants consisted of both adults and adolescents, in order to gain perspectives of adapting to a remarried family from differing individual family members’ stages of development. Participants consisted of 19 parents and 16 adolescents, equaling a total of 35 participants. Triangulation was employed, with an exploratory, descriptive approach. A biographical questionnaire with an open-ended question, in conjunction with a number of structured questionnaires were used to gather the data. These questionnaires were: The Family Hardiness Index (FHI), the Family Time and Routine Index (FTRI), the Social Support Index (SSI), the Family Problem-Solving Communication (FPSC) Index, the Family Crisis-Oriented Personal Evaluation Scales (F-COPES), the Relative and Friend Support Index (RFS), and the Family Attachment and Changeability Index 8 (FACI8). In this study the FACI8 was used as a measure to determine the level of family adaptation. Non-probability purposive and snowball sampling techniques were used. Descriptive statistics were used to analyze the biographical information. Correlation and regression analysis was used to analyze the quantitative data, and content analysis was used to analyze the qualitative data. The results of the quantitative component of the study indicated that there were three significant positive correlations with the FACI8 for both adults and adolescents. These variables were family hardiness (measured by the FHI), family problem solving communication (measured by the FPSC), and family time together and routines (measured by the FTRI). The Social Support subscale of the F-COPES showed a positive correlation with the FACI8 for the adults. The results of the qualitative component of the study revealed that various common themes emerged between the adult and adolescent participants’ responses. These common themes were spirituality; boundaries; respect, love, understanding, compassion and acceptance; communication; flexibility and tolerance; time together, bonding, and routines; and social support. There were four remaining themes that the adults identified as important factors helping them manage being part of a stepfamily. These four remaining themes were equality; forgiveness and acceptance of the past; commitment and being positive; and financial support. The value of the research was discussed. Finally, limitations of the study were discussed, and suggestions were made for future research involving remarried families.

Abstract (sommario):

Stress has been implicated in the onset and exacerbation of psychotic symptoms. Some authors have thus suggested that interventions should target reducing stress levels and improving resilience in patients with early psychosis. However, no study to date has investigated resilience in early psychosis or how resilience influences the relationship between stress and positive symptoms of psychosis. Some authors have also suggested that using a measure of coping with the illness (recovery style), rather than coping with stress per se, may aid in understanding the relationship between stress and symptoms. The present study employed the Brief Resilience Scale and the Can nor-Davidson Resilience Scale to measure two different conceptualisations of resilience. This study also measured stress, recovery style, the severity of positive symptoms of psychosis, and the dimensions of delusions, and auditory hallucinations. The total sample comprised of 44 patients with early psychosis recruited from three Early Intervention in Psychosis Services in London. The main findings were that lower levels of brief resilience and a sealing over recovery style were associated with a greater severity of delusions, when levels of stress were controlled for. Neither resilience nor recovery style moderated the relationship between stress and the dimension of delusions. However, stress, brief resilience, and recovery style significantly accounted for 28% of the variance in delusional severity. Moreover, stress, brief resilience, and recovery style were all found to be significant independent predictors of delusional severity. These findings indicate that high levels of stress, low levels of brief resilience, and a sealing over recovery style were associated with higher levels of delusional severity. Overall, the findings suggest that enhancing stress coping strategies, building resilience in terms of bouncing back from stress, and developing a more integrative recovery style may be helpful in reducing the severity of delusions in patients with early psychosis.

Abstract (sommario):

The rapid growth of wireless communication and widespread access to information has resulted in a strong demand for robust transmission of compressed images over wireless channels. The challenge of robust transmission is to protect the compressed image data against loss, in such a way as to maximize the received image quality. This thesis addresses this problem and provides an investigation of a forward error correction (FEC) technique that has been evaluated in the context of the emerging JPEG2000 standard. Not much effort has been made in the JPEG2000 project regarding error resilience. The only techniques standardized are based on insertion of marker codes in the code-stream, which may be used to restore high-level synchronization between the decoder and the code-stream. This helps to localize error and prevent it from propagating through the entire code-stream. Once synchronization is achieved, additional tools aim to exploit as much of the remaining data as possible. Although these techniques help, they cannot recover lost data. FEC adds redundancy into the bit-stream, in exchange for increased robustness to errors. We investigate unequal protection schemes for JPEG2000 by applying different levels of protection to different quality layers in the code-stream. More particularly, the results reported in this thesis provide guidance concerning the selection of JPEG2000 coding parameters and appropriate combinations of Reed-Solomon (RS) codes for typical wireless bit error rates. We find that unequal protection schemes together with the use of resynchronization makers and some additional tools can significantly improve the image quality in deteriorating channel conditions. The proposed channel coding scheme is easily incorporated into the existing JPEG2000 code-stream structure and experimental results clearly demonstrate the viability of our approach

Abstract (sommario):

Individuals are faced with the prospect of a range of possible losses in later life, relating to one's health, functioning and support network. The view of older adults as being destined to experience psychological distress following such events has begun to be challenged by researchers advocating a strength-based approach to later life. This is in stark contrast to the historical, negative discourse in which older adults are seen as passively accepting or struggling with challenges. The construct of resilience is defined as the ability of individuals to either maintain or return to a position of positive well-being following exposure to unfavourable circumstances. Method A review on resilience in old age and its relationship good mental health was conducted. Additionally, qualitative research using Interpretative Phenomenological Analysis (IPA) enabled exploration of resilience in the personal and relational context via eliciting the experience of spouse carers of individuals with dementia. Results The literature suggested a positive relationship between resilience and good mental health in old age. IPA revealed the presence of four key themes for seven spouse carers demonstrating moderate-very high resilience: 'Making sense of loss'; 'Successfully overcoming the 2 challenges of caring'; 'Recognition of my own needs as a carer' and 'Looking into the future' . Conclusion Resilience does not negate the experience of psychological distress altogether; however, older adults faced with a range of adverse circumstances are able to maintain good psychological functioning and manage well by drawing on personal strengths and external resources. In addition to this, the nature of the marital relationship is important to consider in the context of caring in later life. Clinicians must recognise the presence of resilience in later life, with a view to delivering interventions to promote this, whilst also considering the wider context of aging. Longitudinal research would helpfully provide information on the temporal nature of resilience. 3 •.

Abstract (sommario):

Physicians require discipline, determination, a tolerance for delayed gratification, and brainpower to navigate college, medical school, postgraduate education, and their personal and professional careers. A high degree of resilience is needed for this journey. Adding to research on the concept of resilience, this thesis recognizes two factors beyond one’s control that influence one’s capability for resilience: infant attachment pattern and adverse childhood experiences. Alchemical hermeneutic methodology was employed to examine the influence of these factors on the development of resilience and to explore the vulnerability of medical students and physicians to a failure of resilience. A heuristic approach taken to incorporate the author’s experience and observations as a physician provides evidence of the pressures and potential pitfalls in physician lives. The author proposes changes in medical training and the structure of medical practice that take into account individuals’ strengths and limitations in regard to their capacity for resilience.

Due to the global expansion of Company A's supply chain network, it is becoming more vulnerable to many disruptions. These disruptions often incur additional costs; and require time to respond to and recover from these disruptions. The base paper supply chain was identified as the most vulnerable area of the Company A Jurong and South & Southeast Asia Cluster supply chain; and a multi-stage supply chain was proposed to improve the supply chain's resilience. A statistical model was constructed to select the optimal location of the central warehouse for the proposed multi-stage supply chain. After evaluating the resilience to disruptions and the cost effectiveness of supply chains, the multi-stage supply chain with central warehouse in Tanjung Pelepas, Malaysia was found to be overall most resilient and cost effective among all the supply chains. It also incurs a lower additional cost in the event of a disruption such as changes in exchange rates and demand forecast accuracy, fuel price fluctuation, labor cost increase and shipping disruptions. As a result, establishing this multistage supply chain is recommended.

This study addresses unprivileged dichotomies in an endeavour to make audible the silence surrounding Xhosa family resilience. This study is essentially descriptive and exploratory in nature and directed towards an understanding of the factors contributing to the resilience of Xhosa-speaking, rural black South African families. To contextualise the discussion a selection of theories on resilience are viewed within their cultural contexts. Western psychology’s privileging of a) the scrutiny of pathology while disregarding resilience; of b) white participants to black participants; and c) individuality to relationship centeredness and familial systems; are uncovered and a hypothetical understanding of Xhosa family resilience is construed. The line of thought culminates in the theoretical discussion and empirical exploration of The Resiliency Model of Family Stress, Adjustment and Adaptation (McCubbin, Thompson, & McCubbin, 1996). In the concluding remarks of this project an adaptation of this model, namely the Resiliency Model of Family Stress, Strength, Adjustment and Adaptation, is construed. The derived model is based on an integration of the findings of this study with resilience theory.

ENGLISH ABSTRACT: Using a cross-sectional survey research design the present study aims to explore those resilience factors which enable remarried families to withstand and rebound from the disruptive challenges they face. Furthermore, recovery factors were examined which enabled remarried families to cope more effectively and to emerge har-dier___fr_om a crisis. Remarried families who were married between one to four years, with at least one family member presently in school, were approached to take part in this study. A parent and a child from 38 families independently completed six questionnaires and an open-ended question. It is proposed that the most important resilience factors identified in this study, through qualitative and quantitative measures, include (1) family relationships and support (mutual respect, cooperation and a loving bond), (2) family communication that is affirming, conveying care and support, as well as less incendiary communication that tends to exacerbate a stressful situation, (3) the ability to have a sense of control over outcomes in life by having a active orientation in adjusting to and managing stressful situations, (4) activities and routines that helps the family in spending time together and creating togetherness, (5) a strong marriage relationship (consisting of clearly defined roles, equality and support for each other), (6) support from family and friends, (7) internal and external handling of problems by redefining stressful events and acquiring and accepting social support, (8) spirituality and religion within the family that provides meaning and purpose beyond a crisis situation.

Abstract (sommario):

This thesis analyses resilience as a value which constitutes a telos for contemporary liberal security initiatives. In recent years, resilience strategies have been increasingly employed within liberal states a means of responding to the radical contingency of threat. Rather than seeking to protect a referent through prophylactic measures, resilience strategies aim to optimize the capacity of complex systems to rapidly adapt to, and evolve through, crises. The advent of resilience strategies is premised upon a radical re-evaluation of the referents of security as complex systems. The discovery of the natural resilience of systems integral to liberal life has enabled strategies of emergency governance seeking to harness these processes, and optimize their conditions of ‘freedom’. By naturalising resilience these accounts serve to render its value self-evident. This thesis problematises these accounts by offering a biopolitical genealogy directed at elucidating the historical conditions of possibility for resilience to emerge as a security value. This thesis takes as its empirical referent the case of the historical evolution of a British machinery of governance for responding to emergencies. Analysis makes explicit distinct, and indeed rival, rationalities of governance which can be read from its evolving design. Resilience is demonstrated to be an expression of an emergent neoliberal order of governance. Applying a biopolitical security analytic inspired by Foucault, this genealogy traces the historical consolidation of this order in respect of transformations in the regime of power/knowledge enacted by apparatus of security. A biopolitical genealogy demonstrates that resilience is the correlate of a broader restructuring of the rationalities and practices comprising liberal security governance. By drawing attention to the complex historical processes and significant governmental efforts required to make resilience possible this thesis aims to open up a space through which the value of resilience may be more critically interrogated.

Abstract (sommario):

Este trabajo representa una primera exloración de las interpretaciones generales y especificas que se le atributen a la relación ciudad-resiliencia. Como expresa el titulo, WORBAN es un nuevo catchword que quiere llamar la atención sobre la dimensión global de las ciudades fusionando los términos WORld y urBAN. Debido a la existente variedad de enfoques sobre la resiliencia hemos decidido explorar diferentes casos de estudios, desde ciudades en países en desarrollo hasta como este concepto se pueda aplicar en el planeamiento de ciudad en OCSE. No obstante la potencial borrosidad debida a la amplitud de conceptos y casos distintos desarrollados por esta tesis, un hilo conductor muy definido acompaña el lector a lo largo de todo el recorrido de la tesis: la evolución del concepto de resiliencia asociado respetivamente a la vulnerabilidad al cambio climático, al crecimiento incontrolado (en países en vía de desarrollo) y finalmente en los casos de renovación urbana en grande ciudad globales. En una primera parte la tesis hace un exhaustivo estado de la cuestión sobre el concepto de resiliencia y la emergente metáfora de ciudades resilientes. En la segunda parte se desarrolla, como si se tratase de un proceso de aprendizaje desde lo más sencillo a lo más complejo, tres casos de estudios que tratan respetivamente: a) Resiliencia urbana relacionada con la escala temporal: se trata el concepto de resiliencia y vulnerabilidad (a los impactos del cambio climático). El caso de estudio de Holanda expone el link muy fuerte que el enfoque de protección (resiliencia como resistencia del sistema) tiene con el corto plazo, enfatizando la necesidad y utilidad de relacionar la resiliencia no con estrategias de protección, si no de adaptación y transformación del sistema para hacer frente a la sostenibilidad y sobrevivencia en el largo plazo. b) Resiliencia urbana y sostenibilidad: se relaciona la resiliencia de las ciudades en expansión (gracias a la economía global) en países en vía de desarrollo con los efectos de escalas espaciales que suponen estas transiciones urbanas. Desde este punto de vista el caso de estudio de Marruecos enfatiza el problema emergente de ¿“la resiliencia para quien”?, en cuanto los efectos de escala de la resiliencia de este nuevo perfil de ciudad, globalmente conectada a cadenas de productos y ventas, ya no se sustenta desde los recurso locales. De hecho profundas transformaciones insostenibles y socialmente excluyentes son provocadas por este shift del metabolismo urbano, principalmente por indirectos cambios en los sistemas de valores y en la redistribución del acceso de los servicios de los ecosistemas a escala regional. c) La resiliencia tras la renovación urbana en ciudades globales emergentes: se relaciona la resiliencia con asuntos de poder, un poder que influye en los complejos proceso de producción de los nuevos espacios estratégico metropolitano. El caso de Barcelona subraya el gap entre resiliencia general y especifica, en cuanto diferencia entre voluntades de actores urbanos potentes (key stakeholders) y los ciudadanos locales y sus necesidades (peculiares que pueden ir en contra de los intereses de los actores estratégicos de la ciudad). Desde la suma de la primera parte de review teórico y desde los casos de estudios podemos finalmente considerar la resiliencia urbana como “un marco conceptual multidisciplinar para explorar las capacidades de reacción, reconstrucción, adaptación y transformación de (y en) las ciudades”. En hacer esto, la aplicación de este marco teórico ha reconocido la importancia de considerar la autosuficiencia, la redundancia (disminución de la eficiencia y aumento de la diversidad funcional), el proceso de aprendizaje y la innovación como factores claves de cara a transición hacia ambientes urbanos sostenibles y resilientes. Finalmente, la cuestión fundamental de enfocar siempre de manera critica el estudio de la resiliencia urbana atreves de los criterios ¿“resiliencia de quien y de cara a que”? y de ¿”resiliencia para quien”?.
This Doctoral Thesis represents a first explorative research work over the generic and specific possible interpretations and meanings referred to the relationships between resilience and urban systems. As the title’s catchword introduces, WORBAN is about the world and urban systems resilience as a result of the complex cross scales nature and dimensions of cities, nested in global networks, which definitely represent the mayor driver of global environmental change. Due to the existing variety of multidisciplinary resilience theoretical perspectives we decided to navigate different possible applications and examples of urban resiliency, from developing countries urban growth to urban planning processes in OCSE. Notwithstanding the potential fuzziness of such too broad framework, a specific conceptual common thread develops along the three case studies, the evolution of (urban) resilience perspectives relating it to (urban) vulnerability, (urban) growth and (urban) renewal capacities. A strong literature review is proposed in the first part of the thesis in order to explore the state of the art on resilience and urban resilience emerging paradigms. In the second part, as in the case of a learning process from the easier to the more complex urban resilience perspective, the case studies explain respectively: a) The urban resiliency and timeline: relating resilience to vulnerability and Climate Change threats. The Netherland example builds strong evidences over the short term links with recovery and (system) protection resilient strategies, underlining the usefulness and necessity of framing urban long term resilience toward system structural and functional changes (transitions). b) The urban resiliency and sustainability: relating resilience to fast urbanization processes in developing countries due to global economy and its cross scale effects. The Moroccan case study underline the “resilience for whom” emergent critical perspective, because of the cross scale consequences of the new urban resiliency (and transition) based on global commodity chains better than be sustained from local and regional resources. Deep unsustainable and inequitable transformations emerge from such urban metabolism shift, related to social justice because of a cultural and behavioural induced changes and essential ecosystem services access and benefits re-distribution. c) The urban resiliency behind urban renewal in global cities: relating resilience to power issues in shaping new forms and functions in emerging global cities. Barcelona case study wants to put at the forefront of urban resilience discussion the gap between generic urban resilience (maintain the global network strategic position benefitting markets chains tradeoffs) versus local citizen resilience and needs. From both theoretic reviews and case studies insights we can definitely consider urban resilience as “a multidisciplinary framework to explore the reactive, recovery, adaptive and transformability capacities of (and in) urban systems”. In doing so, the application of this framework has underlined the need of recognizing the benefits of self-sufficiency, redundancy (less efficiency), learning capacities and innovations as core principles for sustainable urban resiliency and transitions. Last but not least, the fundamental research question (and urban resilience focus) must always critically arise the issue of ”resilience of what to what”, and “resilience for whom” that we try to address.

Abstract (sommario):

There are risk factors influencing academic achievement in high school adolescents that can be contextual and individual. Resilience is the ability of individuals to cope with challenging life experiences. The study aimed to prove an hypothetic model of structural equations in two groups of high school students, a dispositional resilience group and a non-dispositional resilience group, to assess the effects of contextual variables, goals and self-regulation on academic achievement. Results show differences in the variables that explain academic achievement in both groups.
Existen factores de riesgo que afectan el rendimiento académico de los adolescentes de preparatoria, estos pueden ser contextuales e individuales. La resiliencia es un fenómeno que implica la superación de los riesgos que se enfrentan. El objetivo del estudio fue probar un modelo hipotético de ecuaciones estructurales en dos grupos de estudiantes de preparatoria, uno de resiliencia y otro de no resiliencia, para evaluar los efectos que tienen las variables contextuales, las metas y la autorregulación sobre el rendimiento académico. Los resultados indican diferencias en las variables que explican el rendimiento de ambos grupos.

Abstract (sommario):

Educational psychologists are expected to offer real-world relevant services. One way to strive towards real-word relevance is for educational psychologists to facilitate resilience by using Ungar’s diagnostic criteria of resilience. However, at this time the usefulness of applying Ungar’s criteria is still unexplored. Thus, this study asked: ‘What insight into the resilience of vulnerable rural adolescents can be achieved by applying Ungar’s diagnostic criteria of resilience to the documents (i.e. paper-and-pencil activities) generated in psycho-educational assessments?’ In answering this question, a qualitative secondary data analysis was conducted of psycho-educational paper-and-pencil activities completed by 65 male and female IsiSwati-speaking Grade 9 learners at a secondary school in Mpumalanga, a remote province in South Africa, during the Flourishing Learning Youth (FLY) study. FLY, a project of the Centre for the Study of Resilience, is based at the University of Pretoria. The a priori categories were sourced from Ungar’s diagnostic criteria and the relevant a priori codes from the review of South African resilience literature. The analysis showed that adolescents were challenged by physical risk, emotional risk and poverty-related risk. Additionally, adolescents were protected by personal resources (agency, self-worth), family resources (role models, supportive parentchild interaction), community resources (role models, community belonging), school resources (teachers as role models and supporters) and macro resources (spirituality). These findings echo extant South African resilience studies and enabled the educational psychologist to ‘diagnose’ resilience for this group of adolescents to better understand the risks to their well-being, the resources that can be leveraged to buffer this risk, and the resources that are absent and must be negotiated.

Abstract (sommario):

It is not too difficult to get an individual to start a physical activity program. It is incredibly difficult to get an individual to maintain a physical activity program over time. All of life’s major and minor inconveniences can become a barrier to performing physical activity, and thus lead to sedentary behavior. The construct of resilience, defined as positively adapting to adverse circumstances, may be helpful in the maintenance of physical activity. However, resilience as a construct is not entirely understood in the current literature. Some theorists suggest resilience is a single construct, while other theorists suggest that resilience is a hierarchical construct that is comprised of other traits. The first portion of this dissertation tested a hierarchical model of resilience. The results of exploratory and confirmatory factors analyses suggest six traits underlie resilience (purpose in life, self-esteem, life satisfaction, cognitive flexibility, proactive coping, and social support). The hierarchical model of resilience found in the first part of this dissertation was then used for the second portion where structural equation modeling tested if resilience mediated the relationship between barriers to physical activity and physical activity. Consistent with a mediational model, the results showed a significant negative relationship between barriers to physical activity and resilience, and a significant positive relationship between resilience and physical activity. However, there was also a significant direct negative link between barriers to physical activity and physical activity. Thus, results suggest that resilience can help mediate the relationship between barriers to activity and being active, although there is also a direct link. Future research may want to examine this relationship longitudinally, and further refine the hierarchical model.

Abstract (sommario):

This research investigates what teaching experiences, strategies and factors impact on early career teachers’ (ECTs’) resilience in secondary colleges in the south of the Netherlands. The ECTs are undergraduate trainee teachers who are enrolled as part-time English as a Foreign language students. Semi-structured interviews were conducted with twelve individual ECTs from three different cohorts, twice in the timespan of two years, in order to get access to the reality of everyday school life viewed through the ECTs’ lens. The three different cohorts consisted of four beginning ECTs, four regular ECTs and four long-term ECTs. Data was collected over a two-year period and included recorded interviews with ECTs, line drawings, relational maps, ECTs’ portfolios and the researcher’s memos. The participants recalled their teaching experiences by means of analysing critical incidents that occurred in their classrooms. The data collection, analysis and discussion were organised into twelve cases. A thematic data analysis was used (Guest et al., 2012; Braun & Clarke, 2013), with the help of ATLAS.ti 7 software. The findings show that the ECTs were often expected to take on the full range of teaching tasks in isolation, with little support to cope with all the demands of their new role. The ECTs found that personal factors, such as self-efficacy and a sense of agency, helped develop their resilience, as well as contextual resources provided in schools and by employing bodies. Although the development of resilience was different for every ECT, participants also shared common strategies that contributed to development of resilience, such as emotional regulation, seeking renewal, goal setting and help seeking, when overcoming the setbacks they experienced. By identifying strategies that impact on resilience, this research has strengthened the guidelines on which induction programmes at Teacher Education Colleges can be made. It is suggested that ECTs are mentored around developing resilience strategies, in order to increase their confidence to work and teach in a new school environment. It is argued that the critical incidents approach, designed to support ECTs in building stories about their teaching experiences, could be used as a teaching methodology for trainee teachers at Teaching Education Colleges.

Abstract (sommario):

During recent years, resilience theory – originally developed in systems ecology – has advanced as a new approach to sustainable development. However, it is still more of an academic theory than a discourse informing environmental politics. The aim of this essay is to study resilience theory as a potential environmental discourse in the making and to outline the political implications it might induce. To gain a more comprehensive knowledge of resilience theory, I study it in relation to already existing environmental discourses. Following earlier research on environmental discourses I define the discourses of ecological modernization, green governmentality and civic environmentalism as occupying the discursive space of environmental politics. Further, I define six central components as characteristics for all environmental discourses. Outlining how both the existing environmental discourses and resilience theory relates to these components enables an understanding of both the political implications of resilience theory and of resilience theory as an environmental discourse in relation to existing environmental discourses. The six central discourse components I define are 1) the view on the nation-state; 2) the view on capitalism; 3) the view on civil society; 4) the view on political order; 5) the view on knowledge; 6) the view on human-nature relations. By doing an empirical textual analysis of academic texts on resilience theory I show that resilience theory assigns a limited role for the nation-state and a very important role for civil society and local actors when it comes to environmental politics. Its view on local actors and civil society is closely related to its relativist view on knowledge. Resilience theory views capitalism as a root of many environmental problems but with some political control and with changing perspectives this can be altered. Furthermore, resilience theory seems to advocate a weak bottom-up perspective on political order. Finally, resilience theory views human-nature relations as relations characterized by human adaptation to the prerequisites of nature. In conclusion, I argue that the empirical analysis show that resilience theory, as an environmental discourse, to a great extent resembles a subdivision of civic environmentalism called participatory multilateralism.

Abstract (sommario):

The current study developed a 40-item situational judgment test (SJT) to measure resilience in context. Undergraduate samples were used in the study and situational stems of the SJT consisted of both daily stressors and major life crises; each response alternative was designed to reflect one of five resilience-related factors. A crowd-sourcing method was utilized to create scoring keys for the SJT. The Resilience SJT demonstrated good psychometric properties, and showed evidence of construct and criterion-related validity. The SJT scores moderately correlated with scores from two resilience Likert scales, a hardiness scale as well as a negative affect scale. Compared to the two Likert-type resilience scales, the SJT demonstrated less overlap with hardiness, positive affect, and negative affect. Moreover, the SJT showed incremental validity in predicting global adjustment, but not academic achievement or college satisfaction, above and beyond the two other resilience measures. Lastly, the study examined different modes of resilient behavior and captured individuals’ mode choice tendencies for resilient responses to adverse situations. The Resilience SJT appears to be a viable alternative to capture resilience. Implications and limitations were discussed.

Abstract (sommario):

Resilience Engineering has evolved during the recent century and could be a good complement to the prevailing ideas concerning safety within the air traffic industry. The concept of Resilience Engineering stresses the fact that in order to keep up the high standard of safety, there must be greater attention directed to the importance of being proactive, and to implement measures before dangerous situations arises. The purpose of our work was to develop the Resilience Analysis Grid (RAG) to help LFV, the leading Air Navigation Service Provider in Sweden, to identify their ability to deal with disturbances and unexpected events. By testing our RAG on seven active air traffic controllers and operational managers, we were able to produce a final set of assertions, with a total number of 22 items, which LFV (or other similar organisations) can use as a foundation for future RAG studies. As a first attempt we also rated the answers which gave us an opportunity to produce a star diagram, showing the relationship between the areas covered by the RAG. During the interviews we discovered that resilience is already today in many aspects a big part of the everyday work and that the RAG method can therefore be applicable in the industry with some modification. However, there are certain areas within LFV that we believe there is room for improvements. We believe that the RAG could serve as a helpful tool in identifying these areas as well as assisting LFV in their striving to remain one of the safest organisations in the world.

Abstract (sommario):

The emergence of resilience in the peacebuilding field shows an important change of paradigm and turn to the local context. So far few ethnographic research has been done to understand how resilience works locally and what are the mechanisms helping individuals to cope and recover from a crisis. This study intends to fill this gap through an ethnographic study of local mechanisms, structures, and understandings of resilience, gathering insights on the perspectives and experiences of women in a conflict-sensitive and post-natural disaster context. It relies on an abductive and inductive methodology using interviews and field-based observations answering the following research questions: 1) How are national and local organizations seeking to enhance the resilience of women in Putumayo? What are the tools and strategies they use? How are these related to their own understanding of resilience? 2) How do the women perceive and act in terms of resilience? How do they manage the consequences of the conflict and the natural catastrophe? What are their strategies of survival? The study brings forth a frame building on the current state of the literature, underlying factors contributing to the resilience of the local population in Putumayo and shedding light on local perspectives to contribute and deepen our current understanding of the concept.

Testo completo

Abstract (sommario):

Resilience has a long history of academic and applied interest, initiated by early realist studies into ‘vulnerable’ populations which explored the finding that not all children in difficult circumstances succumbed to poor outcomes (e.g. Rutter et al, 1975a & 1975b, summarised in Rutter, 1979). Criticisms of this approach generated qualitative studies exploring cultural differences in resilience (e.g. Ungar, 2006), and qualitative studies eliciting the voices of young people in adverse circumstances (e.g. Washington 2008). However these types of studies were still often motivated by application to practice so took a critical realist approach instead of challenging the concept of resilience itself. My interest in resilience emerged through an awareness that in practice young people are often labelled as resilient or vulnerable, with little critical thinking around how such labels might owe more to adult perceptions than to young people’s experiences, particularly, I found, when working with young women. The aim of this research, therefore, was to elicit young women’s views on resilience as a construct. Q methodology was deemed most appropriate for the topic’s complexity and for a participant cohort that may not have personally experienced ‘adverse circumstances’. Thirty eight female participants from one girls’ grammar school sorted fifty-two statements from most unimportant (1) to most important (9). A factor analysis was completed and a four factor solution identified: ‘Resilience is ... supportive relationships and surroundings’, ‘Resilience is... having the individual skills and effort to develop myself and achieve my goals’, ‘Resilience is... having the internal skills and traits to achieve my educational goals’ and ‘Resilience is ... having friends and positive surroundings’. Findings are discussed with relation to existing literature, and the relevance of findings is explored in relation to school and educational psychology practice. Strengths and limitations of the study are considered, and suggestions for future research given.

Abstract (sommario):

Resilience is vital to college and university student success. Furthermore, resilience is necessary for successful leadership. Student leadership programs must consider resilience building as part of successful program development. By considering resilience as a factor in student leadership success and future leadership success, programs may encourage the development of leaders who are highly equipped to lead and continue to lead in the long term. Because of the need to promote resilience building through leadership program development, the researcher sought to explore the potential relationship between participation in leadership activities and student resilience scores. The purpose of this quantitative research was to determine if there were differences in scores on the Connor-Davidson Resilience Scale among undergraduate students involved in honors leadership programs at a 4 year university. Potential links between specially designed 4 year student leadership programs and resilience scores were studied. The number of leadership opportunities participants had engaged in as well as gender, age, and class status (freshman, sophomore, junior, senior) were analyzed. A quantitative nonexperimental survey research design was employed by examining the results of the Connor-Davidson Resilience Scale. The survey link was provided to students during the Fall 2018 semester. Data from the survey were analyzed to address each of the 9 research questions. Seven of the research questions were addressed using ANOVA and 2 research questions were addressed using t tests. No significant relationship was found between overall resilience scores among the 3 activity groups. The results indicated that the majority of the students scored well above the national average score. Although the analyses of relationship between the number of activities and each of the 5 resilience factors were not significant, students who completed 5 or more activities tended to score higher overall. Gender and age showed no significant difference on resilience scores. However, male students scored slightly higher than females, and females scored higher than the national average. The findings from this study may contribute to resilience research, student development research, leadership development research, and educational programming considerations.
