The present paper focuses on the role covered by dynamic models as support for the decision-making process in the evaluation of policies and actions for increasing the resilience of cities and territories. In recent decades, urban resilience has been recognized as a dynamic and multidimensional phenomenon that characterizes urban and metropolitan area dynamics. Therefore, it may be considered a fundamental aspect of urban and territorial planning. The employment of quantitative methods, such as dynamic models, is useful for the prediction of the dynamic behavior of territories and of their resilience. The present work discusses the system dynamics model and the Lotka–Volterra cooperative systems and shows how these models can aid technicians in resilience assessment and also decision makers in the definition of policies and actions, especially if integrated in wide evaluation frameworks for urban resilience achievements. This paper aims to provide an epistemological perspective of the application of dynamic models in resilience assessment, underlying the possible contribution to this issue through the analysis of a real case study and methodological framework. The main objective of this work is to lay the basis for future compared applications of these two models to the same case study.

Cities face unprecedented demographic, environmental, economic, social, and spatial challenges. In recent years, the implementation of nature-based solutions (NBS) is becoming more relevant in cities to improve urban resilience and to cope with climate change. NBS represent cost effective solutions that simultaneously provide environmental, social, and economic benefits and help build resilience. A comprehensive and multi-dimension Resilience Assessment Framework (RAF) to evaluate the NBS contribution to urban resilience, focused on NBS for stormwater management and control, was developed. This RAF is aligned with the RESCCUE RAF and the main assessment frameworks focused on NBS and urban resilience. This RAF for NBS is driven by the definition of resilience objectives and is able to evaluate short- and long-term changes, considering a comprehensive definition of the urban resilience and addressing the environmental, social, and economic capabilities. Regarding the initial resilience maturity and the available information in the city, three analysis degrees were proposed for the RAF application, namely, the essential, complementary, and comprehensive degrees, for which a pre-defined selection of metrics is proposed. This paper aims to present the application of the RAF essential analysis degree and its extensive validation regarding cities with different resilience maturity and available information. The application to seven cities with different resilience and NBS challenges allowed an in-depth validation of the pre-defined metrics included in the RAF essential analysis. In this sense, the analysis of the resilience maturity of the participating cities is presented, the main challenges and consolidated aspects in the cities are identified, and the cities ready to apply the complementary analysis degree are recognized. To conclude, to validate the essential analysis degree, the assessment of the main requirements of the RAF for NBS are verified, based on the RAF metrics results for the cities. In this light, the main requirements of the RAF for NBS were aggregated in three main categories, namely, NBS aspects, resilience capabilities, and the performance, risk and cost analysis.

Abstract. Straightforward communication of monitoring results is of major importance in emergency scenarios relevant to large slope instabilities. Here we describe the communication strategy developed for the Mont de La Saxe rockslide threatening La Palud and Entrèves hamlets in the Courmayeur municipality (Aosta Valley, Italy). Starting from the definition of actions and needs of the landslide management team, including scientists, technicians, civil protection operators, decision makers, and politicians, we show that sharing and disseminating ad hoc information simplifies the understanding of the landslide evolution, as well as the correct communication of the level of criticality.

Matrix Game with Payoffs RepresentedDue to the complexity of information or the inaccuracy of decision-makers’ cognition, it is difficult for experts to quantify the information accurately in the decision-making process. However, the integration of the fuzzy set and game theory provides a way to help decision makers solve the problem. This research aims to develop a methodology for solving matrix game with payoffs represented by triangular dual hesitant fuzzy numbers (TDHFNs). First, the definition of TDHFNs with their cut sets are presented. The inequality relations between two TDHFNs are also introduced. Second, the matrix game with payoffs represented by TDHFNs is investigated. Moreover, two TDHFNs programming models are transformed into two linear programming models to obtain the numerical solution of the proposed fuzzy matrix game. Furthermore, a case study is given to to illustrate the efficiency and applicability of the proposed methodology. Our results also demonstrate the advantage of the proposed concept of TDHFNs.

AbstractCurrent translation studies do not present a clear distinction between ‘translationese’ and ‘interlanguage’, giving rise to conceptual and terminology confusion. To disentangle these two concepts, we start with a relatively conservative working definition of translationese, then find it necessary to first differentiate between direct and inverse translations, according to whether the translator's L1 equals to TL or not. Taking Zhuangzi (a Daoist classic) as a case, we made both inter- and intra-speaker comparisons among Lin Yu-tang's inverse translation, James Legge's direct translation, and the two translators' creative works in English, with well-established language complexity metrics and quantitative methods. Results show that: (1) Inverse and direct translations are remarkably different in terms of complexity; (2) Inverse translation demonstrates both features of interlanguage and translationese, with the former mostly at lexical level and the latter at syntactic level; (3) Similar patterns are also discovered in Lin's other inverse translated works, suggesting our quantitative comparative method proposed may be reliable to some extent. Such results support our proposal that translationese and interlanguage should and can be differentiated for both theoretical and practical purposes.

Abstract The goal of ‘learning’ from peace processes is widely expressed in conflict resolution scholarship and practice but inadequately understood. This article investigates what kinds of knowledge can be learned from a peace process, the theoretical and methodological bases of such learning, and what impact it may have. The article begins with an interdisciplinary discussion of reasons to learn, the kinds of lessons proposed in the peace process literature and how theories of learning may be applied to a peace process. Following this is a case study of the sharing of the Northern Ireland peacemaking experience with other conflict-affected societies, especially through facilitated dialogues between decision-makers. This contributes to a comprehensive ideal model of learning from peace processes – something which, it is argued, may result in ‘transformative learning’ and a ‘policy paradigm shift’ towards de-escalatory conflict management. A definition of a peace process ‘lesson’ is offered to guide future research.

Urban Resilience has recently emerged as a systematic approach to urban sustainability. The malleable definition of resilience has rendered its operationalisation an intriguing task for contemporary cities trying to address their organisational problems and confront uncertainty in a holistic manner. In this article we investigate the implementation challenges emerging for Resilient Strategies by the inattention paid to urban geological risk. We conceptualise urban geological risk as the combination of urban geohazards, geological vulnerability and exposure of the built environment and focus on the case study of Thessaloniki, Greece, a city that joined the 100 Resilient Cities initiative in 2014 and published its “Resilience Strategy 2030” (RS) in 2017. After a review of the RS, historical records of natural hazard events and with evidence gathered through interviews with city officials, we emphasize on earthquakes and surface flooding as the most relevant geohazards for Thessaloniki to tackle in its journey towards urban resilience. First, we examine geological vulnerability to earthquakes in conjunction with exposure of the built environment, as an outcome of ageing building stock, high building densities and the urban configuration, in Acheiropoietos neighbourhood, within the historic centre of the city. Then, we explore geological risk to surface flooding in Perea, in Thermaikos Municipality, with a particular focus on flash floods, by demonstrating how limited consideration of local geomorphology as well as semi-regulated urban expansion and its limited connection with emergency planning increase exposure of the built environment to surface flooding. Finally, we come up with the major implementation challenges Thessaloniki’s RS faces with regard to urban geohazards.

AbstractResearch focuses on linking climate adaptation and disaster risk reduction strategies. The aim of the research is to test an urban resilience assessment tool through a local case study. The tool is based on integrating two methods. Multi-criteria analysis and system dynamics model is used to create a dynamic Urban Resilience Index. For the case study a local medium sized town is chosen in Latvia that is subject to flood risk. The results of the model simulation show that the model is suitable for both short term and long term resilience assessment. Future studies must focus on the precision of such a tool, which in this study could not be evaluated. Overall, the tool presented can contribute to offsetting the existing knowledge gaps between climate adaptation and disaster risk reduction for better policy planning and strengthening urban resilience on the local level.

Women’s empowerment has been at the centre of research focus for many decades. Extant literature examined the process, outcome and various challenges. Some claimed substantial success, while others contradicted with evidence of failure. But the success remains a matter of debate due to lack of empirical evidence of actual empowerment of women around the world. The current study aimed to address this gap by taking a case study method. The study critically evaluates 20 cases carefully sampled to include representatives from the entire country of Bangladesh. The study demonstrates popular beliefs about microfinance often misguide even the borrowers and they start living in a fabricated feeling of empowerment, facing real challenges to achieve true empowerment in their lives. The impact of this finding is twofold; firstly there is a theoretical contribution, where the definition of women’s empowerment is proposed to be revisited considering findings from these cases. And lastly, the policy makers at governmental and non-governmental organisations, and multinational donor agencies need to revise their assessment tools for funding.
