Empowering indigenous enterprise through supplier diversity – The case for Puna Awarau in Aotearoa (New Zealand)

PurposeThis paper aims to demonstrate the role of supplier diversity in empowering indigenous entrepreneurship and the potential socio-economic benefits derived from Puna Awarau (supplier diversity) in Aotearoa (New Zealand).Design/methodology/approachSupplier diversity is an emerging field in Aotearoa (New Zealand). The insights and learnings shared in this article are based on the authors' own professional experiences and insights as supplier diversity practitioners that have shaped, grown and worked in this field.FindingsSupplier diversity is a global practice that is quickly gaining traction in Aotearoa. This is a highly practical tool to create equity for Maori, delivering benefits directly to whanau (families) and bolstering the conditions for entrepreneurship to flourish. Maori fare worst in multiple measures of social and economic well-being in Aotearoa (New Zealand). Super charging the country's fledgling supplier diversity movement is one of the tools in growing Maori entrepreneurship and socio-economic equity at the same time.Social implicationsThere is significant economic and social disparity between Maori and non-Maori. The median net worth of Maori is just a fraction of that of New Zealand (NZ) Europeans. What is clear is that the systems aren't serving Maori people and a “business as usual” approach simply doesn't work. Supplier diversity is a highly practical tool that can create equity for Maori, delivering benefits directly to whanau (families) and bolstering the conditions for entrepreneurship to flourish.Originality/valueThis paper is the one the first academic contributions to the supplier diversity practice in Aotearoa. This article demonstrates the case for supplier diversity, the supplier diversity journey to date and early learnings and insights from practitioners working at the coal face of this emerging practice in Aotearoa.

“Para comer bien y tener un rato ameno y una mesa bien servida…”: la gastronomía marplatense en los avisos publicitarios (diario La Capital, 1939-1990)

The article analyzes the gastronomic offer of Mar del Plata city from the advertisements that appeared in the newspaper La Capital between 1939 and 1990. The text seeks to account for the potentialities and limitations of advertisements as sources for a history of the consumption. These not only provide information about the establishments and their services, but also convey ideals, expectations, customs and experiences that are synthesized around the practice of “eating out”. Based on the information present in the advertisements, we support the idea that the heterogeneity that characterized the Mar del Plata gastronomic market during much of the last century was due to the confluence in the city of different migratory traditions that, likewise, were combined with the phenomenon of mass tourism. This gave rise to a diversified supply and demand that met needs related to food, but above all with sociability and recreation.

Review and comparative analysis of energy security concepts of the European Union and Ukraine

The article is devoted to research and comparison of approaches to ensuring energy security in the European Union (EU) and Ukraine. The article analyzes the main aspects of energy security, such as ensuring energy independence, stability and sustainability of the supply of energy resources, the development of energy efficiency and the use of renewable energy sources, integration into a single energy space, as well as the challenges faced by both sides. The article highlights similarities and differences in approaches to ensuring energy security. Among the common aspects is the recognition of the importance of energy security and the significant attention paid to it by both parties. Both sides are also working on diversifying supply sources and improving energy efficiency. At the same time, there are differences in the development of energy infrastructure and access to resources, where the EU has a developed and diversified system, and Ukraine faces challenges and limitations. The article examines the prospects for the development of the energy sector in both contexts. The EU aims to ensure a stable, stable and sustainable supply of energy resources through the development of a single energy market and cooperation with other countries. Ukraine also has the potential to develop its energy sector, particularly in the field of renewable energy, which can contribute to reducing dependence on imports and ensure a stable and sustainable energy supply. Ukraine's integration into the single energy space of the EU and support and investment from the EU for the development of Ukraine's energy sector are considered important. The article also provides the necessary steps to ensure energy security in Ukraine. Among them, it is worth highlighting the modernization of the energy system, cooperation with the EU and other countries, diversification of supply, improvement of energy infrastructure, increasing energy awareness of the population and harmonization of legislation with European standards. Different research methods were used to obtain reasonable results. The article analyzed the official documents and strategies of the EU and Ukraine related to energy security. This analysis made it possible to identify the main principles and approaches used in each of the concepts. The article is supported by a review of current scientific research and publications on energy security that relate to the EU and Ukraine. This literature review identified key aspects and trends in the field. Deduction and induction methods were used for comparative analysis. The application of the deduction method made it possible to proceed from the general provisions and principles formulated in official documents to derive specific conclusions regarding energy security. With the help of the induction method, an analysis of specific facts and data was carried out, from which generalizations and the formulation of general conclusions were made. The general conclusion of the article is that both the European Union and Ukraine strive to ensure energy security, but their approaches and priorities may differ. The challenges facing both sides require continued effort and cooperation to achieve a sustainable and sustainable energy future.

China's Path towards Global Green Governance on Rare Earth Elements: Challenges and Opportunities

In light of surging demands for critical minerals and its rising profile as a global provider, China can no longer dismiss the negative ecological externalities resulting from its unregulated, near-monopoly production of rare earth elements (REE) since the 1970s. REE, consisting of 17 elements with naturally enhanced chemical properties, is critical for manufacturing future green infrastructures and technologies. However, the extraction and refining processes are resource-intensive and toxic to the immediate environment, further exacerbated by improper radioactive waste management, underfunded land restoration, and illegal mining. By extension, China’s supply supremacy came at the cost of socio-ecological deprivation disproportionately experienced by the local community compared to the beneficiary beyond borders. This study aims to assess the challenges and opportunities for China as they seek global leadership in green governance through its post-reform sustainable development model guided by Ecological Civilization (EC) principle. Using narrative analysis methods, we seek to assess the intersection among three threads: the historical account of China’s REE global dominance, their elite-based approach to governance, and the unmitigated socio-ecological impacts on the local community; regarding EC and its derivatives. While domestic consolidation is strategically integral to China’s EC-guided development agenda, it poses dormant risks of supply volatility for international markets, and innovative secondary production becomes the new source of competitive edge for supply diversification and norm-making power.

Modeling the systemic trade risk of crude oil from a network perspective, combined with a sentiment proxy

Introduction: Trade networks of crude oil are susceptible to cascade of initial shocks that increase systemic trade risks and threaten energy security. This study introduces a novel method of modelling systemic trade risk of crude oil which is combined with a sentiment proxy from a network perspective.Method: We construct sentiment instability to evaluate the uncertainty of crude oil trade in a country and use the PageRank algorithm to measure supplier diversity from a network perspective instead of direct trade partners.Result: At the global level, we show that the distribution of systemic oil trade risk has an obvious heterogeneity and a significant negative correlation between systemic trade risk of crude oil and trade volume volatility. At the regional level, we compare the systemic trade risk of crude oil between China and America and systemic trade risks show strongly significant correlations with the price volatility in both China and America. Furthermore, the structure of trade network can effectively reduce the systemic risk in America while it increases the systemic trade risk in China.Discussion: Our results can give a reason for an irrational practice of Chinese crude oil imports which are “buying when the price is rising and not buying when the price is declining”.

An assessment of the strategies for the energy-critical elements necessary for the development of sustainable energy sources.

There have been several strategies developed to increase the diversified supply of energy so that it can meet all of the future demands for energy. As a result, to ensure a healthy and sustainable energy future, it is imperative to warrant reliable and diverse energy supply sources if the "green energy economy" is to be realized. The purpose of developing and deploying clean energy technologies is to improve our overall energy security, reduce our carbon footprint, and ensure that the generation of energy is secure and reliable in the future, making sure that we can spur economic growth in the future. In this paper, advancements in alternative sources of energy sustainability and strategies will be examined to ensure there will be enough fuel to supply all the future demands for energy. Several emerging clean energy technologies rely heavily on the availability of materials that exhibit unique properties that are necessary for their development. This paper examines the roles that rare earth and other energy-critical materials play in securing a clean energy economy and the development of clean energy economies in general. For the development of these technologies to be successful and sustainable, a number of these energy-critical materials are at risk of becoming unavailable. This is due to their limited availability, disruptions in supply, and a lack of suitable resources for their development. An action plan focusing on producing energy-critical materials in energy-efficient ways is discussed as part of an initiative to advance the development of clean and sustainable energy.

Research on Green and Low-Carbon Development Path of the Electric Power Industry

In the analogy where achieving the “carbon peaking and carbon neutrality” goals (the “dual carbon” goals) is compared to a battle, energy is the main battlefield, and electric power the main force. The low-carbon transformation path of the electric power industry exerts fundamental impact on progress towards carbon peaking and carbon neutrality of the whole society. Therefore, this paper first analyzes challenges and opportunities faced by the electric power industry to achieve the “dual carbon” goals; secondly, on the basis of deep low-carbon, zero-carbon and negative-carbon scenarios of the electric power industry, this paper quantifies and delves into the consumption structure of primary energy and final energy, as well as the future development positioning and trend of different categories of energy. Based on the research results, this paper proposes low-carbon transformation path of the electric power system at the stages of carbon peaking, deep low-carbon and carbon neutrality, and analyzes the trend of power supply cost changes in different scenarios. On this basis, a series of implementation key points and measures are proposed to adapt to green and low-carbon transformation of the electric power industry, covering areas such as coal-fired electric power development positioning, new energy development and utilization, diversified supply and demand, new energy industry chain, and power supply costs, and so forth.

A Systematic Review of Indigenous Food Plant Usage in Southern Africa

Indigenous food plants provide various social functions; they are crucial to food supply diversification efforts, and they improve food and nutrition security. Research has shown that indigenous foods’ nutritional potential and advantages have yet to be adequately appreciated and explored. This systematic review discusses the various elements contributing to IF promotion, which may help increase their intake. Therefore, a systematic literature review was conducted to determine the availability, regularity of consumption, utilisation, preparation, harvesting, and preservation of indigenous foods. Additionally, this review details the knowledge, perceptions, and beliefs of IFs under these themes. The findings of this systematic review highlight the importance of promoting IFs through policies, the development of capabilities and skills, in-depth research, and an extensive indigenous food plant composition. The fact that Southern African populations do not value indigenous foods and their potential advantages appears to be a significant barrier. Furthermore, the younger generation has lost access to the older generations’ indigenous food knowledge. Thus, the preservation of indigenous food knowledge in books and continuing education of the younger generation about the importance of consuming indigenous foods and the nutrition content they contain may help with its uptake.

Design and implementation of smart meter for PQ-based tariff computation for LV distribution network consumers

The drastic rise of renewable energy, electric vehicles, and electronic loads is deteriorating distribution networks' power quality (PQ), affecting utility companies' profitability and consumer satisfaction. Therefore, it is imperative to implement a PQ monitoring system at the consumer level and enforce a quality-constrained tariff scheme to regulate the PQ issues. This article presents the design and development of a low-cost smart energy meter that accurately measures 25 essential PQ parameters every 0.2 s and transmits the data to a server at one-minute intervals. Further, these parameters are used for remote PQ monitoring and PQ-based tariff implementation to regulate reactive power and harmonics in the distribution network. The smart meter is calibrated and tested with standard meters and validated in laboratory-scaled diversified supply voltage and load scenarios, demonstrating accuracy, practicality, and affordability. Concludes it as a viable option to monetize and regulate the PQ issues in distribution networks or smart grids.

The impact of Russia’s war against Ukraine on Sino-European relations

ABSTRACT This paper analyses the development of Sino-European relations following Russia’s attack on Ukraine. I argue that the behaviour of European and Chinese leaders is driven by the availability and attractiveness of outside options. While both sides want to reduce their dependence on the other, neither actor seeks a radical decoupling. Measures to diversify supply chains, the negotiation of new trade agreements around the world, and the ‘technology war’ have made Beijing’s outside options less favourable. Europeans are emboldened to articulate their interests more forcefully, particularly in the areas of human rights, scrutiny of foreign funding, and economic coercion. China, in turn, provides diplomatic cover for Russia but resists undermining Western sanctions.

Digging DEEP: Futuristic building blocks of omni-channel healthcare supply chains resiliency using machine learning approach

There is a lack of studies which have explored the factors of omni-channel healthcare supply chain resiliency (OHSCR). Thus, the current study explores the resiliency factors of healthcare supply chains (HSCs) and the development of futuristic blocks of OHSCR. In the first phase of the study, the resiliency factors of HSCs were identified through an extensive literature review and expert interviews. In the second phase, a machine learning approach, i.e., K-means clustering, was used to develop the futuristic blocks of OHSCR. Lastly, in the third phase, implications and future research propositions were discussed. The findings of this study suggest that the healthcare sector evaluating OHSCR should focus on six key building blocks: data-driven management and transformative technological adoption, flexible and transparent organisational management system, robust and diversified supply chain system, responsible and customer-centric supply chain, information sharing and knowledge management, and strategic alignment and network ecosystem. A conceptual research framework is also proposed to support future research.

Supply diversification under random yield: The impact of price postponement

Supply diversification and pricing are two common mechanisms for dealing with supply yield uncertainty. This paper characterizes a firm's pricing and sourcing decisions under supply yield uncertainty, and studies the interplay between the two mechanisms. We compare the optimal sourcing decisions under two distinct pricing schemes: (1) ex ante pricing—the firm simultaneously makes the sales price and sourcing decisions before production takes place; (2) responsive pricing—the pricing decision is postponed until after the production yield realization. Although the firm is better off with responsive pricing, the effect of price postponement on the optimal sourcing decision and the firm's need for supply diversification varies and is influenced by factors such as unit procurement cost, supply portfolio, and supply reliability. For the case of one unreliable supplier, we show that responsive pricing mitigates the overage and underage risks imposed by yield uncertainty, and results in a lower optimal order quantity than that under ex ante pricing when the procurement cost is low, and a higher quantity otherwise. For the case of two unreliable suppliers, we show that responsive pricing promotes supply diversification when the sole‐sourced supplier's reliability is low, and discourages when it is high. By contrast, when the sole‐sourced supplier's reliability is moderate, responsive pricing promotes supply diversification when its unit procurement cost is low and discourages otherwise. The composition of supply portfolio also has a fundamental impact on such strategic interplay: When the supply portfolio consists of one unreliable and one reliable supplier, diversified sourcing is never optimal under ex ante pricing, but may be optimal under responsive pricing. Thus, responsive pricing promotes dual sourcing in this setting. We also conduct comprehensive numerical experiments to both confirm the robustness of the main results and derive additional insights.

The Use of the Hierarchical Method to Group the Countries of the European Union According to their Energy and Climate Policies Adopted on the Basis of Directives of the European Parliament

Abstract Subject and purpose of work The European Union’s energy policy focuses mainly on three areas: reducing greenhouse gas emissions in the energy sector by increasing the use of RES, reducing emissions of harmful pollutants, and increasing the efficiency of the electricity used. Sustainable energy use, on the other hand, is clearly associated with an increased use of renewable energy sources, which ensures energy security, as well as diversification of energy supplies that sustain and improve the quality of the environment. The purpose of the paper is to present the diversity of the countries of the European Union in terms of the actions they take in the field of energy and climate policy resulting from the European Union directives. Materials and methods Based on the goals of energy policy presented in the EU directives a number of indicators were selected in order to describe the actions taken by EU member states. After a substantive and statistical verification, 6 variables were left. The use of the Ward’s method made it possible to create groups of countries that are similar in terms of their energy and climate policies. Conclusions The most favorable situation in terms of the effects of the climate and energy policy can be observed in the current leaders, that is in Sweden and Finland as well as in Estonia. Central European countries, mainly Poland, have high-emission economies, accompanied by low investment in modern environmentally friendly technologies. This is manifested, among others, in high concentrations of particulate matter, which contributes to poor air quality, categories in which Poland has some of the worst results in the entire EU.

Energy security: the role of shale technology

Sustainable energy systems are sensitive to the countries’ energy portfolio decisions, shaping geopolitics and contributing to the global energy security (ES). Accordingly, this paper applies the “Markov regime-switching” method to explore the impact of “the North American shale technology” (NAST) on behavioral regimes of the US energy security measurements (ESM), e.g., diversity of primary energy demand ({mathrm{ESI}}_{mathrm{I}}), net energy import dependence ({mathrm{ESI}}_{mathrm{II}}), non-fossil fuel resource portfolio ({mathrm{ESI}}_{mathrm{III}}), and crude oil import dependency ({mathrm{ESI}}_{mathrm{IV}}). The findings confirm time-varying and asymmetric behavior of the US ESM before and after the NAST. Specifically, the overall interaction of substitution effect and scale effect of NAST strengthens the US energy systems through {mathrm{ESI}}_{mathrm{I}}, {mathrm{ESI}}_{mathrm{III}}, and {mathrm{ESI}}_{mathrm{IV}}, while {mathrm{ESI}}_{mathrm{II}} leads to higher risks of the US energy supply security. Consequently, the shale reserves development, diversification of primary energy demand and import supply, and advanced energy transport and trading policies, are suggested to overcome the barriers in achieving (i) availability, (ii) accessibility, (iii) affordability, and (iv) acceptability aspects of ES and vulnerability reduction of the US energy systems in respect of risk and resilience.

Design of a high-efficiency electrolytic energy conversion system based on equilibrium analysis of electric-field and flow-field through simulation and experiments

In the context of sudden changes in global energy supply patterns, promoting the diversification of energy supply is an important movement for the sustainable development of the economy. Nuclear energy as a green and clean energy source has undergone rapid development. About 60 wt% of the world's fluorine production is used to produce uranium, a fuel for nuclear power plants. However, fluorine as a necessary raw material facing the challenges of high energy consumption and short lifespan of the electrolysis system. To overcome these drawbacks, this study aims to develop a high-efficiency electrolytic energy conversion system. Therefore, to optimize the design of the electrolysis system, the relationships between the electric field, the flow field and the electrode/electrolyzer geometry are simulated. Then, the simulation results are verified and further corrected by corrosion experiments. Subsequently, the key factors affecting the performance of the electrolyzer are obtained from the bubble separation experiment and simulation. Finally, a high-efficient electrolysis system is established and successfully put into industrial operation. In conclusion, in the course of model calculations, the method of reducing energy consumption is put forward, and the energy consumption is reduced from 17,000 to 14,980 kWh/ton by actual production, and the service life of carbon anode is extended from 90 days to 243 days. The breakthrough in fluorine electrolysis provides practical guidance for improving the performance of the electrolysis process.

Gas Crisis as a Precursor of European Recession

The reasons for the gas crisis in the European Union, which began in 2021, were the instability of renewable energy, the redirection of LNG to the premium Asian market, anti-Russian sanctions, and a decrease in gas imports from Russia. Despite the measures taken by the EU authorities (energy conservation, diversification of gas supplies and energy sources, financial support for the householders and businesses), the gas crisis will worsen in 2023. The gas crisis, superimposed on the mistakes of the monetary policy of the European authorities, accelerates inflation, intensifying structural imbalances in the EU economy and bringing recession closer. The symptoms of a recession can already be observed with the help of key indicators, which include indexes of industrial production and Manufacturing PMI, trade balance, inflation, unemployment rate, retail sales and GDP. The economic downturn in the European Union will negatively affect the dynamics of production in the largest trading partners (China, the US and the UK) and may trigger a recession in the global economy.

Photovoltaic Companies on the Warsaw Stock Exchange—Another Speculative Bubble or a Sign of the Times?

Renewable energy sources are an attractive alternative to fossil fuels for several reasons. Firstly, these are ecological arguments, mainly reducing greenhouse gas emissions. Secondly, there are legal issues, particularly the obligations of the European Community countries in the field of climate as part of the implementation of the European Green Deal and the joint achievement of 40% of energy from renewable sources by 2030. Thirdly, these are international issues, primarily regarding reducing dependence on uncertain oil or gas markets. And finally, they may be economic reasons, such as diversification of energy supplies and associated costs, as well as opportunities for profits on the capital market. In Poland, over the last decade, a certain kind of boom in photovoltaics has been visible, both in terms of the number of companies dealing with solar collectors, as well as the annual increase in new capacity, or the level of installed capacity. Also, on the Warsaw Stock Exchange, photovoltaic companies have introduced much confusion in the tier of quotations in recent years. Solar energy has become a kind of gateway for companies to increase their results, stock exchange quotations, or acquire new customers. It is not surprising that more and more investors want to invest their money in this segment. Given the above, this article attempts to answer the question: Is there a risk of a stock market bubble among photovoltaic companies in the near future? For this purpose, we used the financial indicators of photovoltaic companies listed on the Warsaw Stock Exchange, and with the help of the Taxonomic Measure of Attractiveness of Investments, we created rankings of the investment attractiveness of these companies in 2017-2019. The leaders include companies listed on the main market as well as in the alternative trading system of the Warsaw Stock Exchange. It should be borne in mind that regardless of the undertaken diversification and analytical activities, the risk of an investment bubble has been and will remain an indispensable element in the functioning of every capital market in the world.
