[ { "abstract" : "The Sendai Framework for Disaster Risk Reduction 2015–2030 (SFDRR) recognises the benefits of MHEW systems and enshrines them in one of its seven global targets: “Substantially increase the availability of and access to multi-hazard early warning systems and disaster risk information and assessments to people by 2030”. This chapter describes the activities and results from a three-year initiative to strengthen multi-hazard early warning (MHEW) for coastal hazards by developing the capacity of higher education institutes (HEI) in Asia. The CABARET project was established to promote international cooperation on MHEW at the regional level between HEIs in Asia and Europe, and among Asian HEIs. It involved a consortium of fifteen European and Asian HEIs from Bulgaria, Indonesia, Latvia, Maldives, Malta, Myanmar, Philippines, Spain, Sri Lanka and the UK, as well as three non-academic actors who provided a vital link to wider socio-economic perspectives. The consortium of HEIs set out to build capacity, foster regional integration and cooperation through joint initiatives, and share good practices. They also sought to strengthen relations between HEIs and the wider economic and social environment through a specific focus on coastal communities, many of whom are under severe pressure from planned and unplanned development, population growth and human induced vulnerability, coastal hazards with increasing frequency and magnitude, and the impacts of global climate change. This chapter describes the project’s efforts to better understand the research and innovative capacity needs across the Asian HEIs and to build their capacity to support the development of a more comprehensive, multi-hazard approach to early warning. The chapter concludes by examining the key achievements of the project, including an increase in innovation capacity and the promotion of regional cooperation.", "creators" : [ { "id" : "", "institution" : "Department of Biological and Geographical Sciences", "name" : { "family" : "Hemachandra", "given" : "Kinkini" }, "orcid" : null }, { "id" : "R.Haigh@hud.ac.uk", "institution" : "Department of Biological and Geographical Sciences", "name" : { "family" : "Haigh", "given" : "Richard" }, "orcid" : "0000-0001-7347-7043" }, { "id" : "D.Amaratunga@hud.ac.uk", "institution" : "Department of Biological and Geographical Sciences", "name" : { "family" : "Amaratunga", "given" : "Dilanthi" }, "orcid" : "0000-0002-1682-5301" } ], "date" : "2021-09-12", "date_type" : "published", "id_number" : "10.1007/978-3-030-73003-1_35", "language" : "english", "official_url" : "https://pure.hud.ac.uk/en/publications/increasing-the-capacity-of-higher-education-to-strengthen-multi-h", "publisher" : "Springer, Cham", "title" : "Increasing the Capacity of Higher Education to Strengthen Multi-Hazard Early Warning in Asia", "type" : "article" }, { "abstract" : "Tsunami is a hydrological hazard that has attracted a significant attention in the disaster risk reduction (DRR) discipline since the phenomena of unprecedented coastal urbanization has been increasing the causes for tsunami risk in coastal cities.

Hence, the tsunami warning and evacuation planning is considered as a critical need in the DRR strategies of the Padang city. This research is aimed at evaluating the relevant capacities within the Padang city for improving the preparedness for tsunami hazard. The overall preparedness of the city for potential tsunami impacts has been assessed by calculating the preparedness index (PI) which is composed of four key indicators; Knowledge and attitudes (KAP), emergency response plan (EP), early warning system (WS), mobilization of resources (RM). The results recorded 74/100 for PI which categorizes the city as ‘ready for preparedness’ signifying the availability of high capacities for the improvement of tsunami warning and evacuation planning. The result of the PI can be further interpreted to identify the structural measures such as vertical shelters and evacuation routes for the better preparedness against tsunami hazard.", "creators" : [ { "id" : "D.Amaratunga@hud.ac.uk", "institution" : "Department of Biological and Geographical Sciences", "name" : { "family" : "Amaratunga", "given" : "Dilanthi" }, "orcid" : "0000-0002-1682-5301" }, { "id" : "R.Haigh@hud.ac.uk", "institution" : "Department of Biological and Geographical Sciences", "name" : { "family" : "Haigh", "given" : "Richard" }, "orcid" : "0000-0001-7347-7043" }, { "id" : "", "institution" : "School of Applied Sciences", "name" : { "family" : "Ashar", "given" : "F." }, "orcid" : null }, { "id" : "M.Senevirathne@hud.ac.uk", "institution" : "School of Applied Sciences", "name" : { "family" : "Senevirathne", "given" : "M." }, "orcid" : "0000-0002-0888-3499" } ], "date" : "2021-09-12", "date_type" : "published", "id_number" : "10.1007/978-3-030-73003-1_34", "language" : "english", "official_url" : "https://pure.hud.ac.uk/en/publications/a-preparedness-index-pi-to-assess-the-capacities-for-tsunami-warn", "publisher" : "Springer, Cham", "title" : "A Preparedness Index (PI) to Assess the Capacities for Tsunami Warning and Evacuation Planning: A Case Study from Padang City, Indonesia", "type" : "article" }, { "abstract" : "Community-based knowledge has protected communities from natural hazards for decades. This knowledge, gathered throughout generations from observation, has increased the capability of people to understand the behaviour patterns of natural hazards specific to their local environment. Many people have used these observations to develop their own sets of defence strategies. Recent disaster risk reduction (DRR) policies have highlighted the importance of community-based knowledge and previous studies have shown the contribution they can make towards productive DRR practices in different context. However, they also show a failure to translate that knowledge into practice. This chapter presents a study to understand the role of community-based knowledge in disaster risk reduction (DRR). It is based on a systematic literature review using academic literature published online after 2010, as well as recent international policy documents related to DRR. The study addresses three guiding questions: What are the definitions and terminology associated with community-based knowledge? How is community-based knowledge addressed within international policies on DRR? What is the contribution of community-based knowledge to current DRR practices? A key word search was carried out using the terms Community-based knowledge, local knowledge, traditional knowledge, indigenous knowledge, disaster management and disaster risk reduction. The literature highlights that recent development activities and DRR measures have considered community-based knowledge as an important factor in sustainable development, yet there is a gap in integrating these measures into practice.

On the other end, climate change, extreme events, and associated hydrometeorological disasters, directly and indirectly, setback the development gains. Climate change mitigation can be accelerated through sound development policies, strategies, and programs. Climate change adaptation, coupled with upscaled disaster risk management, contributes to reducing the negative impacts of extreme events and other socio-economic shocks. Climate change, weather extremes, and disasters adversely impact food production and productivity in developing countries. Food security and access to food are considered fundamental human rights. The Sustainable Development Goals (SDGs), goal number two, “Zero Hunger” to be achieved by the year 2030, highlights the importance of food security across the countries. However, achieving the ‘Zero Hunger’ milestone has been challenged due to climate change, extreme events, and disasters. Although there is a general consensus about the linkages between climate change and food security, the nexus between disasters, climate change, and sustainable development and their interconnections with food security have not been fully explored or well understood. Asia region, which homes to two-third of the world population and the highest number of reported annual disaster events, face unprecedented challenges in meeting food security and access to foods in the coming decade.

Such shortcomings in policy compliance, which is also observed in many other countries, can be due to their poor technical understanding, implementation gaps, institutional weaknesses, interferences of influential parties etc. That indicates the necessity for efforts in better risk governance and importance of positioning the same around the theme of sustainable development. It also entails the introduction of appropriate institutional arrangement; the creation of appropriate policy & legal framework and the continuous resource allocations for mitigation of landslide risk. Within this context, setting up a development framework inclusive of landslide risk management interventions and climate change adaptation, will have very important long-term outcomes not only in reducing the future landslide risk but also in sustaining the gains of development.

Although it is widely accepted that urban centres are more exposed to natural hazards than rural areas, rapid urbanization may not be the only explanatory factor for city vulnerability, the lack of adequate disaster-resilient infrastructural facilities equally contributes to it. The increased population in these cities with little or no adequate infrastructure services and housing make people resort to living in slums and hazard-prone areas such as floodplains, steep slopes, low-lying lands, riverine and coastal areas. The sudden outburst of disasters in such cities without better-built disaster-resilient infrastructure can lead to destructions and losses which undermines the efforts geared towards the achievement of the Sustainable Development Goals (SDGs). In this context, this chapter aims at understanding the role of disaster-resilient cities in facilitating the achievement of SDGs in Nigerian urban settings through literature review and semi-structured interviews. Nigeria is one of the developing countries in the African continent that is experiencing rapid urbanization and regularly prone to natural hazards such as floods and droughts without the infrastructural facilities capable of making its cities resilient to these hazards. The city of Aba in Nigeria, the case study of this research, is one of such cities. The interviewees discussed the role of disaster risk resilient cities in relation to the 17 SDGs, demonstrating that the availability of disaster risk resilient infrastructure in Aba will help to reduce the impacts of disasters and facilitate the achievement of the SDGs such as poverty eradication, zero hunger and quality education. Based on this, they argue that without disaster risk resilient structures in the city under study, disaster-induced destructions and losses can hinder the achievement of sustainable development. Thus, the findings vividly highlight the role of disaster risk resilient cities in facilitating the achievement of the SDGs in cities, arguing that urban disaster destructions and losses are developmental setbacks. Therefore, the chapter recommends that to achieve the SDGs, the government, urban planners, and other organizations in these cities should strategically take action on creating disaster risks resilient cities.", "creators" : [ { "id" : "", "institution" : "School of Applied Sciences", "name" : { "family" : "Smart", "given" : "Lilian N." }, "orcid" : null }, { "id" : "R.Haigh@hud.ac.uk", "institution" : "Department of Biological and Geographical Sciences", "name" : { "family" : "Haigh", "given" : "Richard" }, "orcid" : "0000-0001-7347-7043" }, { "id" : "D.Amaratunga@hud.ac.uk", "institution" : "Department of Biological and Geographical Sciences", "name" : { "family" : "Amaratunga", "given" : "Dilanthi" }, "orcid" : "0000-0002-1682-5301" } ], "date" : "2021-09-12", "date_type" : "published", "id_number" : "10.1007/978-3-030-73003-1_9", "language" : "english", "official_url" : "https://pure.hud.ac.uk/en/publications/role-of-disaster-risk-resilient-cities-in-facilitating-the-achiev", "publisher" : "Springer, Cham", "title" : "Role of Disaster Risk Resilient Cities in Facilitating the Achievement of Sustainable Development", "type" : "article" }, { "abstract" : "The significance of developing robust multi-stakeholder Disaster Resilience (DR) mechanisms has multiplied in the last few decades.

It is in this context that this paper attempts to investigate the status of Research and Innovation (R&I) within HEIs in Sri Lanka. It examines the existing policies, infrastructure and the status of the research staff in relation to R&I. Key informant interviews were conducted with a purposively selected sample of academics from national universities, policy makers, and directors who are actively engaged in DR and Disaster Management (DM). The findings reveal that Sri Lanka lacks a national policy on R&I, which in turn has reduced the support received by researchers from HEIs. Furthermore, lack of systematic training, absence of multi-stakeholder participation and limited permanent research staff were identified as major barriers. In addition, the findings suggest that Sri Lankan HEIs should focus on establishing a national policy to develop R&I, allocate more funds to carryout R&I within HEIs and establish a permanent cadre who is highly qualified in research to further improve R&I capacities. It concludes that the prevailing capacities of Sri Lankan HEIs are inadequate and emphasizes the importance of taking prompt measures to improve R&I capacities in HEIs.", "creators" : [ { "id" : "", "institution" : "University of Colombo", "name" : { "family" : "Fernando", "given" : "Nishara" }, "orcid" : null }, { "id" : "", "institution" : "University of Colombo", "name" : { "family" : "Hettige", "given" : "S.

For short duration lithium-ion batteries provide the best performance, with storage efficiencies between 70 and 95%. Hydrogen based technologies can be developed as an attractive storage option for longer storage durations. But, common polymer electrolyte membrane (PEM) electrolyzers and fuel cells have round-trip system efficiencies of only 30–40%, and platinum and rare iridium catalysts are needed. Thus, it is a major challenge to increase the energy conversion efficiency of electrolyzers and fuel cells significantly, and at the same time to use non-precious catalysts. The present work experimentally examines the usefulness of a bifunctional NiC catalyst in two different assemblies: an alkaline fuel cell (AFC) with electrolyte gap and gas diffusion electrodes and an alkaline membrane electrolyzer (AEL). The performance characteristics of the novel system are compared with a reversible PEM fuel cell. While the AEL reaches acceptable power densities, the PEM based system still performs better than the proposed system. The AFC with an electrolyte gap provides remarkable results as it shows vanishingly small overvoltage during electrolysis at temperatures around 90 °C and current density of 100 mA cm−2: an electrolyzer efficiency of about 100% could be achieved for the single cell. The round-trip efficiency was also very high: 65% were realized with 50 mA cm−2.

We use a sample comprising 6,978 firm-year observations of firms listed in the USA (S&P 500), Canada (S&P-TSX 221) and the UK (FTSE 350) from 2013 to 2019.

In contrast, firms’ adoption of international guidelines and environmental, social, and governance (ESG) ratings cannot predict the firm value in the study context.

However, there is very little VBA research that recognises bisexuality as a separate category. Therefore, the main aim of this quasi-experimental study was to investigate the role of female victim sexuality (bisexuality, homosexuality, and heterosexuality) and observer sex in the attribution of blame to the victim and perpetrator of IPV. Participants (N = 232; aged 18-24 years, M = 21.05, SD = 1.73) were randomly assigned into one of four conditions (heterosexual victim, bisexual victim with same-sex partner, bisexual victim with different-sex partner, homosexual victim), each containing a vignette portraying IPV within a relationship. Randomisation checks were performed to ensure that participants in the four conditions did not differ significantly on underlying attitudes (institutional heterosexism, aversive heterosexism, heterosexual privilege, sexist attitudes, just world beliefs) that may have affected their responses on outcomes measures. Main analyses demonstrated that bisexual victims with a same-sex partner received the highest attribution of blame, whereas perpetrators in this condition received the lowest blame attribution. Male participants attributed significantly higher blame to victims than did female participants, regardless of victim sexuality. These findings substantiate the role of victim sexuality and observer sex in IPV blame attribution patterns.

Data were collected among a general population sample of British 10-year-old children extracted from the UK Household Longitudinal Study (N = 601). Seven items characterised ACEs, comprising parent-report physical discipline, emotional abuse, supervisory neglect, maternal psychological distress, and child-report parental educational disinterest, bullying victimisation, and adverse neighbourhood. Outcome measures were derived from the self-report Strengths and Difficulties Questionnaire including total difficulties, emotional symptoms, conduct problems, hyperactivity, peer problems, and prosocial behaviour. Latent class analysis resulted in a 3-class solution: low ACEs, household challenges, community challenges. Compared to the other classes, the community challenges class scored substantially worse on total difficulties, emotional symptoms, and peer subscales. The cumulative risk score was associated with all outcomes except prosocial behaviour. Cumulative risk models accounted for a larger proportion of variance compared with the latent class models, except for peer problems which the person-centred model explained better.
