- Description: The application of true cost accounting (TCA) at farm level requires a common framework and metric for measuring, capturing and valuing sustainability. We propose such a framework and farm metric that build on the four capitals—natural, social, human and produced—that are essential for sustainability. The framework is developed by reviewing the scientific and technical literature on various approaches and tools that have been used to measure farm sustainability. We use quantifiable aspects of sustainability in the farm metrics. The farm sustainability metrics comprise four capitals with 11 categories and 33 indicators. These indicators can be assessed using bio-physical assessment, descriptive or quantitative methods. Once this information is compiled for a farm, then some of the categories can be monetised to reflect all the costs and benefits of using state-of-the-art TCA. There is a need to establish benchmarks and standards for each of the four types of capitals and indicators for the comparison of food systems. We believe the use of this comprehensive framework and farm metrics will help to correct several deficiencies of the current food system. We conclude by highlighting the benefits and limitations in the use of farm metrics. Measuring all positive and negative externalities at farm level can shift global food systems towards sustainability. Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

- Description: The global agenda for sustainable development includes the alleviation of poverty and hunger by developing sustainable agriculture and food systems. Intensive farming systems and its variations, such as sustainable intensification or ecological intensification, are currently being pro-moted as technologies that can improve agricultural productivity and reduce environmental im-pacts. However, these are focused only on per-hectare productivity with growing negative impacts on local culture and the environment. This study identifies the negative impacts of crop-and live-stock-based farming systems on the Indo-Gangetic plains, as well as in the USA, China, and South America as an example of key challenges in global agriculture. These impacts are classified into environmental, social, economic, and health impacts. An alternative paradigm is proposed to over-come some of the shortcomings of current global agriculture. This new bottom-up paradigm is based on three indicators that are fundamental to achieve the environmental, economic, and social sustainability of agriculture and food systems. These are divided into technical, geographic, and social indicators and have been analysed for four farming systems—low-input, high-input, organic, and desired farming systems. Seven global geographic regions have been analysed in terms of their socio-economic indicators and status of agriculture in order to develop pathways for the implementation of the new paradigm. The pathway for change suggested in this paper includes a focus on research and training, policy and institutional changes, and an evaluation of the costs and benefits, and changes in production models that consider scale and sustainability metrics and include inno-vations in consultation with all stakeholders. This new paradigm has the potential to direct global efforts towards more local and regional solutions, which are community driven and constitute a ‘bottom-up’ approach. © 2021 by the author.

- Description: Blockchain technology (BCT) has been gaining popularity due to its benefits for almost every industry. However, despite its benefits, the organizational adoption of BCT is rather limited. This lack of uptake motivated us to identify the factors that influence the adoption of BCT from an organizational perspective. In doing this, we reviewed the BCT literature, interviewed BCT experts, and proposed a research model based on the TOE framework. Specifically, we theorized the role of technological (perceived benefits, compatibility, information transparency, and disintermediation), organizational (organization innovativeness, organizational learning capability, and top management support), and environmental (competition intensity, government support, trading partners readiness, and standards uncertainty) factors in the organizational adoption of BCT in Australia. We confirmed the model with a sample of adopters and potential adopter organizations in Aus-tralia. The results show a significant role of the proposed factors in the organizational adoption of BCT in Australia. Additionally, we found that the relationship between the influential factors and BCT adoption is moderated by “perceived risks”. The study extends the TOE framework by adding factors that were ignored in previous studies on BCT adoption, such as perceived information trans-parency, perceived disintermediation, organizational innovativeness, organizational learning capa-bility, and standards uncertainty. © 2021 by the authors.

- Description: Sustainable Human Resource Management (HRM), has the potential to facilitate organi-sations development of principles, policies and practices for the challenges of the 21st century. How-ever, to do this we argue a fundamental element in this process has yet to be fully addressed and incorporated into the theory and practice of sustainable HRM; this is employee voice. Additionally, the actual and potential role of trade unions in facilitating employee voice is yet to be conceptualised within sustainable HRM literature. We argue that the development of effective employee voice mechanisms is vital in the implementation and maintenance of sustainable HRM. In this conceptual paper, we outline the nature of the voice architecture, the impact of the employment relationship on voice mechanisms, how it can be effectively measured, and propose a framework for further exploring these concepts. These key factors we identify as critical in implementing and assessing the effectiveness of the relationship between employee voice and sustainable HRM, to potentially serve as a basis of future research into sustainable HRM. © 2021 by the authors.

- Description: Globally, the most problematic greenhouse gas (GHG) emissions of ruminant livestock is methane (CH4), with a global warming potential 25 times that of carbon dioxide. This work considers the emissions and production effects of powdered activated carbon (PAC) at 0.5% by dry matter (DM) on methanogenic rumen flora as the major source of dairy cattle enteric methane emissions. In total, 180 dairy cattle located in Brymaroo, Queensland (QLD), Australia, were studied in a three-cycle repeated measures ANOVA format with a 4 week primary interval. Emissions eructated during milking and in faecal deposits were measured, and in addition, 16S rRNA gene sequencing was performed to determine the collective populations of prokaryotic bacteria and archaea as well methanogenic communities for each treatment. Moreover, 0.5% PAC addition reduced CH4 emissions by 30-40% and CO2 emissions by 10%, while improving daily milk production by 3.43%, milk protein by 2.63% and milk fat by 6.32%, on average for the herd (p < 0.001 in all cases). rRNA gene sequencing showed populations of methanogenic flora decreased by 30% on average with a corresponding increase in the nonmethanogenic species. We strongly advocate further on-farm trials with the dietary addition of PAC in ruminant diets to mitigate emissions while maintaining or improving productivity. © 2021 by the authors.

- Description: This study aims at modeling the compaction characteristics of fine-grained soils blended with sand-sized (0.075–4.75 mm) recycled tire-derived aggregates (TDAs). Model development and calibration were performed using a large and diverse database of 100 soil–TDA compaction tests (with the TDA-to-soil dry mass ratio ≤ 30%) assembled from the literature. Following a comprehensive statistical analysis, it is demonstrated that the optimum moisture content (OMC) and maximum dry unit weight (MDUW) for soil–TDA blends (across different soil types, TDA particle sizes and compaction energy levels) can be expressed as universal power functions of the OMC and MDUW of the unamended soil, along with the soil to soil–TDA specific gravity ratio. Employing the Bland– Altman analysis, the 95% upper and lower (water content) agreement limits between the predicted and measured OMC values were, respectively, obtained as +1.09% and −1.23%, both of which can be considered negligible for practical applications. For the MDUW predictions, these limits were calculated as +0.67 and −0.71 kN/m3, which (like the OMC) can be deemed acceptable for prediction purposes. Having established the OMC and MDUW of the unamended fine-grained soil, the em-pirical models proposed in this study offer a practical procedure towards predicting the compaction characteristics of the soil–TDA blends without the hurdles of performing separate laboratory compaction tests, and thus can be employed in practice for preliminary design assessments and/or soil– TDA optimization studies. © 2021 by the authors.

- Description: In the last two decades, the retail sector has experienced unprecedented upheaval, having severe implications for economic development and sustenance of traditional inner-city retail dis-tricts. In the city of Christchurch, New Zealand, this effect has been exacerbated by a series of earthquakes in 2010/2011 which destroyed much of the traditional retail precinct of the city. After exten-sive rebuild activity of the city’s infrastructure, the momentum of retailers returning to the inner city was initially sluggish but eventually gathered speed supported by increased international vis-itation. In early 2020, the return to retail normality came to an abrupt halt after the emergence of the COVID-19 pandemic. This study uses spending and transaction data to analyze the compounding impact of the earthquake’s aftermath, shift to online shopping, and the retail disruption in the Christchurch central retail precinct because of COVID-19. The findings illustrate how consumers through their spending respond to different types of external shocks, altering their consumption patterns and retail mode (offline and online) to cope with an ever-changing retail landscape. Each event triggers different spending patterns that have some similarities but also stark differences, having implications for a sustainable and resilient retail industry in Christchurch. Implications for urban retail precinct development are also discussed. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

- Description: Software risks are a common phenomenon in the software development lifecycle, and risks emerge into larger problems if they are not dealt with on time. Software risk management is a strategy that focuses on the identification, management, and mitigation of the risk factors in the software development lifecycle. The management itself depends on the nature, size, and skill of the project under consideration. This paper proposes a model that deals with identifying and dealing with the risk factors by introducing different observatory and participatory project factors. It is as-sumed that most of the risk factors can be dealt with by doing effective business processing that in response deals with the orientation of risks and elimination or reduction of those risk factors that emerge over time. The model proposes different combinations of resource allocation that can help us conclude a software project with an extended amount of acceptability. This paper presents a Risk Reduction Model, which effectively handles the application development risks. The model can syn-chronize its working with medium to large‐scale software projects. The reduction in software failures positively affects the software development environment, and the software failures shall re-duce consequently. © 2021 by the authors.
