Application of Timber and Wood-based Materials in Architectural Design using Multi-objective Optimisation Tools
Get PDFDigital fabrication leads architects and structural engineers to modify the design optimisation methodology. The designers, as never before, are facing new technologies developed in the search for new materials based, among others, on wood components and the improvement of manufacturing methods at the same time. In this process, the material and manufacturing technology adjustment to desired aesthetic outcomes is possible not only by the material used but also by the self-organisation of the structure\u27s optimisation. New fabrication techniques linked with topology optimising software change traditional load-bearing systems designing using timber and wood-based materials. Multi-objective optimisation research indicates that timber might be a comprehensive material based on various applications from low-tech to cutting-edge contemporary fabrication technologies. The article presents new tools and methods for the optimisation of structural elements. A case study based on interdisciplinary architectural and structural optimisation suggests the possible effective research-based design. Comparing contemporary buildings with wood load-bearing structures explains timber usage\u27s diversity and characteristics in modern design
A Comparative Study of Energy Performance in Educational Buildings in the UAE
Get PDFSustainability has gained popularity and importance around the globe due to the ever-increasing effects of climate change and global warming on Earth. As of the 21st century, human endeavour has caused an enormous amount of damage to the environmental ecological system. Among which, one of the major contributors to the increase in the environmental issues and CO2 emissions are the conventional sources of energy, especially in the built environment. Globally, the built environment accounts for 12 percent of the world’s drinkable water, 40 percent of energy wastage and 35 percent of scarce natural resources, which in turn produces 40 percent of the total global carbon emission. Among which are educational buildings which tend to be a major contributor (as most of these facilities are old and conventionally built in the mid-1900s) Thus, with the education sector being an essential part of society, it becomes important to determine the energy performance and carbon footprint of these buildings. The United Arab Emirates (UAE) vision 2021 highlights the country\u27s approach to the importance of providing the best education and adopting sustainable environmental infrastructure. Therefore, this study adopts a methodological approach based on semi-structured interviews and surveys, in order to compare the energy performance of three educational buildings within Higher Education establishments in the UAE as a case study. The study also evaluates the end user’s awareness of the importance of sustainable practices in the buildings and their preference for these buildings. The findings of this study conclude that Net Zero Energy Buildings (NZEBs) are the most efficient buildings in terms of energy performance, carbon consumption and heat generated. Therefore, it is important that the integration of these types of buildings is considered in educational establishments
Trends in rural fiscal decentralisation in India’s Karnataka state: a focus on public health
Get PDFFor decades, decentralisation reforms have been seen as a powerful instrument by health policy advocates to improve health sector performance in developing countries. In India, the 73rd Constitutional Amendment introduced in 1992 called for strengthening the fiscal autonomy and service delivery capacity of rural local governments. This paper explores how decentralised governance influences public health sector resource allocation, equity and efficiency in rural Karnataka. For this, the authors analysed administrative data published by the Karnataka state government to create tailored standardised performance measures that capture the degree of local governments’ fiscal discretion in implementing public health programmes from 2011–18 at the district level. The findings highlight sector-specific differences in fiscal autonomy, ranging from high local discretion over funds in the nutrition sector to very limited discretion in the medical and public health sector. They also show that decentralised public health funding is not well-targeted to areas of greatest need in Karnatak
Making Sense of Multi-Actor Social Collaboration in Building Information Modelling Level 2 Projects: A Case in Malaysia
Get PDFDespite the diversity of thinking among the scholars on building information modelling (BIM) collaboration, there is a paucity of studies that capture the dimension of social collaboration in BIM projects. This study attempts to develop a comprehensive understanding on the key attributes of multi-actor social collaboration in BIM projects through the experience of practitioners in BIM-Level 2 construction project. The success of multi-actor social collaboration has been investigated through structured interviews with 22 BIM practitioners in a BIM-Level 2 project based on an established theoretical framework of social collaboration. The findings indicted that relationship-oriented attributes; relational contracts BIM execution plan; guideline, standard and work process manual approaches; employer information requirement (EIR); understanding roles and leadership; commitment from top management; resources; training, team building workshop and awareness program; coordination; and understanding on the theoretical knowledge of BIM are of importance towards multi-actor social BIM collaboration. This study acknowledges that the success of multi-actor social collaboration was influenced by the consolidation of many attributes, and it extends the dominant relationship between related attributes for multi-actor social collaboration based on the "best practice approach", which includes dominant-centric attributes (i.e., behaviour formation, procurement model and support principles). This research contributes to the body of BIM knowledge in the construction domain by focusing on what it takes to achieve greater social collaboration in BIM Level 2 projects
A Relational Approach to Transforming Power in a Community-University Partnership
Get PDFWe use a relational understanding of power to analyze power dynamics at the institutional and interpersonal levels in our multi-year Co-Education/Co-Research (CORE) partnership between Tufts University Department of Urban and Environmental Policy and Planning (UEP) and Dudley Street Neighborhood Initiative (DSNI). Power in community-university partnerships is often examined only at the institutional level, conceiving of power as a resource to be balanced and shared. Indeed, CORE has advanced institutional shifts through co-governance, equitable funding, co-production of curriculum and cross-flow of people. While institutional policies and practices are critical, they alone do not transform deep-seated hierarchies that value university knowledge, practices and people over community. To understand how intertwined interpersonal and institutional practices can reproduce or transform these cultural and ideological dynamics, we use a relational approach, understanding that power flows in and through all relations. As community members, students and faculty, we reflect on the contradictions we have encountered in CORE. We examine how we reinforce the dominance of academic over community knowledge, even as we leverage institutional power to further community goals. These tensions can be opportunities for shifting, disrupting and transforming towards more equitable relations, but they can also reproduce and reinforce the status quo. Through reflective practice and a relational ethic of care, we can try to recognize when we might be shifting power relations and when we might be reproducing them. This is messy work that requires a lot of communication, trust, reflection and time. A relational approach to power provides hope that we can be part of the change we seek in all of our relations, every day. And it reminds us that no matter what we have institutionalised or encoded, our individual beings, organizations and communities are always in a process of becoming.
 
Where’s the Love? Recentering Indigenous and Feminist Ethics of Care for Engaged Climate Research
Get PDFAcross a range of environmental change and crisis-driven research fields, including conservation, climate change and sustainability studies, the rhetoric of participatory and engaged research has become somewhat of a normative and mainstream mantra. Aligning with cautionary tales of participatory approaches, this article suggests that, all too often, ‘engaged’ research is taken up uncritically and without care, often by pragmatist, post-positivist and neoliberal action-oriented researchers, for whom the radical and relational practice of PAR is paradigmatically (ontologically, epistemologically and/or axiologically) incommensurable. Resisting depoliticised and rationalist interpretations of participatory methodologies, I strive in this article to hold space for the political, relational and ethical dimensions of collaboration and engagement.
Drawing on four years of collaborative ethnographic climate research in the Peruvian Andes with campesinos of Quilcayhuanca, I argue that resituating Participatory Action Research (PAR) within a feminist and indigenous ethics of care more fully aligns with the radical participatory praxis for culturally appropriate transformation and the liberation of oppressed groups. Thus, I do not abandon the participatory methodology altogether, rather this article provides a hopeful reworking of the participatory methodology and, specifically, participatory and community-based adaptation (CBA) practices, in terms of a feminist and indigenous praxis of love-care-response. In so doing, I strive to reclaim the more radical feminist and Indigenous elements – the affective, relational and political origins of collaborative knowledge production – and rethink research in the rupture of climate crises, relationally. The ethico-political frictions and tensions inherent in engaged climate scholarship are drawn into sharp relief, and deep reflection on the responsibility researchers take on when asking questions in spaces and times of ecological loss, trauma and grief is offered
When Consensus Falters, We Co-create: Attending to Power in a Practitioner/Scholar Partnership to Amplify Newcomer Belonging
Get PDFThis article interrogates the politics of belonging in scholar–practitioner collaborations by analysing and reflecting upon a group project that advocated for a more equitable approach to newcomer belonging and integration in an urban setting in the United States. The structure of our collaboration revealed unaddressed and unspoken dynamics that collectively reinforced boundaries and hierarchies in our group, despite a level of intentionality around democratic praxis among the community-engaged scholars who initially brought participants together. The article asks: How can we work towards a notion of belonging if we haven’t worked out an equitable approach within our own group where everyone, including newcomers, feels like they belong? The article relies on a methodology of critical reflexive dialogue between the four co-authors – two scholars and two practitioners – to analyse and reflect on the ways that power imbalances are bound up in questions of belonging and representation
Transnational Memory and the Fukushima Disaster: Memories of Japan in Australian Anti-nuclear Activism
Get PDFThis paper argues for the importance of transnational memories in framing Australian anti-nuclear activism after the Fukushima disaster. Japan looms large in the transnational nuclear imaginary. Commemorating Hiroshima as the site of the first wartime use of nuclear weapons has been a long-standing practice in the Australian anti-nuclear movement and the day has been linked to a variety of issues including weapons and uranium mining. As Australia began exporting uranium to Japan in the 1970s, Australia-Japan relations took on a new meaning for the Indigenous Traditional Owners from whose land uranium was extracted. After Fukushima, these complex transnational memories formed the basis for an orientation towards Japan by Indigenous land rights activists and for the anti-nuclear movement as a whole. This paper argues that despite tenuous organizational links between the two countries, transnational memories drove Australian anti-nuclear activists to seek connections with Japan after the Fukushima disaster. The mobilisation of these collective memories helps us to understand how transnational social movements evolve and how they construct globalisation from below in the Asia-Pacific region.fic region
Factors Inhibiting Corporate Social Responsibility Initiatives Among Construction Companies
Get PDFCorporate Social Responsibility (CSR) is one of the best strategies that companies used in minimising negative societal and environmental impacts, enhancing economic development and improving social progress concurrently. However, there are many factors discouraging construction companies to implement or establish a CSR plan. Furthermore, there are few empirical studies in relation to CSR in construction, and the majority of empirical research on CSR implementation are rooted in the organisational and economic context of the developed world. Therefore, the current study seeks to investigate the factors inhibiting CSR initiatives among construction companies within the context of a developing country such as Nigeria. The study adopted a survey research method. Questionnaires were administered to a purposively selected group of managing directors, directors, other top construction professionals or management personnel involved in the operation of small, medium and large construction companies in Nigeria. A total of 196 questionnaires were administered among the sampled respondents out of which a total of 119 representing 61% were adequately filled and returned. The data collected were analysed using descriptive and inferential statistics. The results revealed corruption tendencies borne from lack of transparency between companies and government, lack of CSR benefits measurement, lack of financial resources, inadequate support from top management and lack of governmental support as the top five factors inhibiting CSR initiatives among construction companies in Nigeria. In addition, the results from the study revealed that, there is no statistically significant difference in factors inhibiting CSR in construction between indigenous and expatriate and partly indigenous/partly expatriate companies. The findings provide in-depth insight of the factors inhibiting CSR programmes in construction that can help top construction professionals and management personnel in construction companies facilitate development of strategies required to mitigate the factors inhibiting CSR programmes
