The study attempts to estimate farm subsidies the governments can save by transitioning to a millet-based production system, replacing GHG emission-intensive crops.

Abstract

Purpose

The study attempts to estimate farm subsidies the governments can save by transitioning to a millet-based production system, replacing GHG emission-intensive crops.

Design/methodology/approach

It updates a 131 × 131 commodity input–output (IO) table of the year 2015–16 into 2021–22 using the RAS procedure and simulates the economy-wide impacts of replacing rice and wheat with pearl millet and sorghum using consumption and production approaches. It then quantifies fertilizer, electricity and credit subsidy expenses the government can save through this intervention. It also estimates the potential reduction in GHG emissions that the transition could bring about. India is taken as a case.

Findings

Results show pearl millet expansion brings greater benefits to the government. It is estimated that when households return to their pearl millet consumption rates that prevailed in the early-reform period, this could save the Indian government Rs. 622 crores (USD 75 m). The savings shall be reinvested in agriculture to finance climate adaptation/mitigation efforts, contributing to a sustainable food system. Net GHG emissions also decline by 3.3–3.6 MMT CO2e.

Practical implications

Indian government has been actively aiming to bring down paddy areas since 2013–14 through the Crop Diversification Program and promoting millets (and pulses and oilseeds) on these farms. The prime reason is to check rapidly declining groundwater irrigation in Green Revolution states. Regulations in the past in these states have not brought the intended results. Meanwhile, electricity and fertilizers are heavily subsidized for agriculture. A slight shift in the cropping system can help conserve these resources. Meanwhile, GHG emissions could also be brought down and subsidies could well be saved. The results of the study indicate the same.

Social implications

A less warm society is what governments and nongovernment organizations across the world are aiming for at present. Financial implications affect actions against climate change to a greater extent, apart from technological innovations. The effects of policy strategies discussed in the study, taking a large country as a case, when implemented appropriately around the regions, could help move a step closer to action against climate change.

Originality/value

The paper addresses a key but rarely explored research issue – that how a climate-sensitive crop choice will help reduce the government’s fiscal burden to finance climate adaption/mitigation. It also offers a mechanism to estimate the benefits within an economy-wide framework.

Abstract

Purpose

This study aims to understand the challenges of 5G deployment in India from the perspectives of telecom operators. These challenges are also mapped to different contexts within the technological-organizational-environmental (TOE) framework.

Design/methodology/approach

The study uses a qualitative approach comprising in-depth semi-structured interviews of employees working in telecom companies in India. Thematic analysis is used to analyse the qualitative data.

Findings

The author has identified nine challenges that are categorized under three dimensions of the TOE framework. Specifically, the findings indicate three technological challenges: hardware/device challenges, security concerns and limited use cases; two organization challenges: financial challenges and lack of skilled workforce; and four environmental challenges: inadequate infrastructure, regulatory and administrative challenges, consumers’ attitudes and competitive market conditions.

Practical implications

The results of this study would help understand the key factors that can act as barriers to the 5G rollout in India. Based on the findings of the study, the government and regulatory bodies could design conducive policies and regulatory frameworks to successfully deploy 5G in India.

Originality/value

The study is one of the very few studies to empirically examine the telecom operators’ perspectives on the challenges of 5G deployment in India. The study contributes to the TOE framework as its application in the context of identifying barriers to 5G deployment is probably for the first time.

This paper aims to propose a two-stage vibration isolation system for large airborne equipment to isolate aircraft vibration load.

Abstract

Purpose

This paper aims to propose a two-stage vibration isolation system for large airborne equipment to isolate aircraft vibration load.

Design/methodology/approach

First, the vibration isolation law of the discrete model of large airborne equipment under different damping ratios, stiffness ratios and mass ratios is analyzed, which guides the establishment of a three-dimensional solid model of large airborne equipment. Subsequently, the vibration isolation transfer efficiency is analyzed based on the three-dimensional model of the airborne equipment, and the angular and linear vibration responses of the two-stage vibration isolation system under different frequencies are studied.

Findings

Finally, studies have shown that the steady-state angular vibration at the non-resonant frequency changes little. In contrast, the maximum angular vibration at the resonance peak reaches 0.0033 rad, at least 20 times the response at the non-resonant frequency. The linear vibration at the resonant frequency is at least 2.14 times the response at the non-resonant frequency. Obviously, the amplification factor of linear vibration is less than that of angular vibration, and angular vibration has the most significant effect on the internal vibration of airborne equipment.

Originality/value

The two-stage vibration isolation equipment designed in this paper has a positive guiding significance for the vibration isolation design of large airborne equipment.

Abstract

Purpose

This paper aims to draw lessons for telecommunications (telecom) network deployment in India, from a study of policy and regulatory approaches taken by other federal administrations in streamlining processes for site clearances, grant of rights of way (RoW) and approvals for local infrastructure deployment and sharing. With the urgent need for setting up small cells and rapid fiberisation of networks in the 5G era, the importance of such processes has gained prominence.

Design/methodology/approach

The authors adopt qualitative thematic content analysis with three-tier coding and classification to identify themes in archival and current documentary data and information obtained from subject-matter experts in the countries studied.

Findings

Formulation and implementation of telecom policy is led by national governments. However, national telecom administrations, in recognition of new needs, have co-opted states and local authorities as partners in development of telecom networks, providing the overall framework, guidance and appropriate incentives where required.

Practical implications

This cooperative model could work well in India, where telecom policy making and regulation is the prerogative of the central government, but administration of RoW and local clearances for cable laying, tower siting and associated infrastructure activities for expanding telecom networks are left to decentralised decision-making in the states and local bodies.

Originality/value

This research attempts to sytematise, thematise and draw cross-country comparisons to inform regulatory and administrative policy for 5G infrastructure rollout in India.

Abstract

Purpose

The challenges faced by China's high-end equipment manufacturing (HEEM) industry are becoming clearer in the process of global supply chain (GSC) reconfiguration. The purpose of this study is to investigate how China's HEEM industry has been affected by the GSC reconfiguration, as well as its short- and long-term strategies.

Design/methodology/approach

The authors adopted a multi-method approach. Interviews were conducted in Phase 1, while a three-round Delphi survey was conducted in Phase 2 to reach consensus at the industry level.

Findings

The GSC reconfiguration affected China's HEEM supply chain (SC). Its direct effects include longer lead times, higher purchasing prices and inconsistent supply and inventory levels of key imported components and materials. Its indirect effects include inconsistent product quality and cash flows. In the short term, China's HEEM enterprises have sought to employ localized substitutes, while long-term strategies include continuous technological innovation, industry upgrades and developing SC resilience.

Originality/value

This study not only encourages Chinese HEEM enterprises to undertake a comprehensive examination of their respective industries but also provides practical insights for SC scholars, policymakers and international stakeholders interested in how China's HEEM industry adapts to the GSC reconfiguration and gains global market share.

Abstract

Purpose

Recently, powerful instruments for biomedical engineering research studies, including disease modeling, drug designing and nano-drug delivering, have been extremely investigated by researchers. Particularly, investigation in various microfluidics techniques and novel biomedical approaches for microfluidic-based substrate have progressed in recent years, and therefore, various cell culture platforms have been manufactured for these types of approaches. These microinstruments, known as tissue chip platforms, mimic in vivo living tissue and exhibit more physiologically similar vitro models of human tissues. Using lab-on-a-chip technologies in vitro cell culturing quickly caused in optimized systems of tissues compared to static culture. These chipsets prepare cell culture media to mimic physiological reactions and behaviors.

Design/methodology/approach

The authors used the application of lab chip instruments as a versatile tool for point of health-care (PHC) applications, and the authors applied a current progress in various platforms toward biochip DNA sensors as an alternative to the general bio electrochemical sensors. Basically, optical sensing is related to the intercalation between glass surfaces containing biomolecules with fluorescence and, subsequently, its reflected light that arises from the characteristics of the chemical agents. Recently, various techniques using optical fiber have progressed significantly, and researchers apply highlighted remarks and future perspectives of these kinds of platforms for PHC applications.

Findings

The authors assembled several microfluidic chips through cell culture and immune-fluorescent, as well as using microscopy measurement and image analysis for RNA sequencing. By this work, several chip assemblies were fabricated, and the application of the fluidic routing mechanism enables us to provide chip-to-chip communication with a variety of tissue-on-a-chip. By lab-on-a-chip techniques, the authors exhibited that coating the cell membrane via poly-dopamine and collagen was the best cell membrane coating due to the monolayer growth and differentiation of the cell types during the differentiation period. The authors found the artificial membrane, through coating with Collagen-A, has improved the growth of mouse podocytes cells-5 compared with the fibronectin-coated membrane.

Originality/value

The authors could distinguish the differences across the patient cohort when they used a collagen-coated microfluidic chip. For instance, von Willebrand factor, a blood glycoprotein that promotes hemostasis, can be identified and measured through these type-coated microfluidic chips.

Abstract

This chapter aims to shed light on the hidden benefits and losses of US-China trade within the framework of unequal exchange theory. After presenting the evolutions of the trade balance between China and the United States, we propose two methods for measuring the unequal exchange between them: one considers the labor content directly incorporated into the exchange; the other focuses on the international values with input-output tables. This allows to present a synthesis of sectoral analyses. Our results show a significant unequal exchange in US-China trade over 1995–2014, the United States being actually the main beneficiary of this trade. Both methods exhibit the inequality in exchange tending to decrease over time; China's disadvantage has been gradually reducing from the 2000s. We finally suggest that the relative decline in the hegemonic status of the United States in this bilateral unequal relationship could help explain its decision to launch its trade war with China.

Abstract

Learning outcomes

This case study is focused on strategic management of Huawei in sustaining the competitive position in the smartphone market. The discussions in the case study begins with the big picture of “Made in China 2025” policy and China’s 14th Five-Year Plan 2021–2025 attempting to change the country’s image from imitation to innovation. The case study then focuses on Huawei, the major provider of network equipment and smartphones, with the alignment of the national policy. The case demonstrates the difficulties faced by Huawei as a result of US ban. The students are challenged to perform in-depth discussions on various issues guided by the instructor using this Teaching Note. The teaching objectives are as follows: students should be able to analyse Huawei business environment and its strategic capabilities in the smartphone market; students should be able to evaluate the extent to which the effects of US sanction would have on Huawei smartphone operation; and students should be able to evaluate the strategies for Huawei to regain a leading position and achieve competitive advantage in the global smartphone market.

Case overview/synopsis

Huawei is the leading company in the information and communications technology (ICT) sector. Ren Zhengfei, Chief Executive Officer (CEO) of Huawei, has set the vision of building a global company that could rival the best in the world. Huawei’s heavy investments in research and development (R&D) have brought the company to be a leading brand in the international market. Huawei was charged as a security threat by the Donald Trump administration in 2019. The USA and its allies banned Huawei products, causing the smartphone shipments plummeted dramatically. The case presents a protagonist, Ren Zhengfei, CEO of Huawei, who built the business from a small company to a leading global ICT company. The growth of Huawei was struck by the US sanction with the supply chain being disrupted by a shortage of advanced chip technology to run the smartphone business. The dilemma addressed in this case study is concerned with how Ren Zhengfei could steer the company out of the crisis.

Complexity academic level

This case study was written for use in the courses of Innovation Management and Technology Strategy. The case is designed to support learning at various levels including the graduate, postgraduate and executive classes. Apart from the guided questions (assignment questions provided in the next section), the instructors should consider which specific areas of Huawei should be further explored to support the class discussions to benefit the students at different levels.
