This study conceptually investigates the impact of quantum computers on blockchains within the supply chain context. Powerful quantum computers enable attackers to break into blockchains by rapid inverse calculations of mathematical problems that are the core of one of the main blockchain security foundations, known as asymmetric cryptography. They are also able to violate the integrity of public blockchains like bitcoin through mining acceleration. Hence, quantum computers can engender threats to the supply chain users of blockchain. On the other hand, there are ongoing efforts to create a quantum-resistant solution. One approach for such a solution is to utilize quantum tools themselves. Moreover, sufficiently powerful quantum computers are still being developed, and it is still unclear whether a quantum solution will arrive first or vice versa. The contrasting duality of quantum computers and lack of a clear picture over the timing of the arrival of a solution and threats give rise to the uncertainty that might hinder the attractiveness of blockchains for supply chains.

AbstractIn order to select the heterogeneous multicore fiber (MCF) configuration with ultra-low crosstalk and low peak bending radius, comparative crosstalk analysis have been done for the three possible core configurations, namely, Configuration 1 - different refractive index (R.I.) and different radius, Configuration 2 - different R.I., and Configuration 3 - different radius. Using the coupled mode equation and the simplified expressions of mode coupling coefficient (MCC) for different configurations of heterogeneous cores, the crosstalk performance of all the heterogeneous MCF configurations along with the homogeneous MCF have been investigated analytically with respect to core pitch (D) and fiber bending radius (${R}_{b}$). Further, these expressions of MCC have been extended to obtain the simplified expressions of MCC for the estimation of crosstalk levels in respective trench-assisted (TA) heterogeneous MCF configurations. It is observed from the analysis that in Configuration 1, crosstalk level is lowest and the rate of decrease in the crosstalk with respect to the core pitch is highest compared to the other configurations of heterogeneous MCF. The values of crosstalk obtained analytically have been validated by comparing it with the values obtained from finite element method (FEM) based numerical simulation results. Further, we have investigated the impact of a fixed percent change (5%) in the core parameters (radius and/or R.I.) of one of the core of a homogeneous MCF, to realize the different heterogeneous MCF configurations, on the variations in crosstalk levels, difference in the mode effective refractive index of the core 1 and core 2 ($\Delta {n}_{eff}={n}_{eff1}-{n}_{eff2}$), and the peak bending radius (${R}_{pk}$). For the same percent variations (5%) in the core parameters (radius and/or R.I.) of different configurations of cores (Config. 1-Config. 3), Config. 1 MCF has highest variation in $\Delta {n}_{eff}$ value compared to other configurations of MCF. Further, this highest variation in $\Delta {n}_{eff}$ value of Config. 1 MCF results in smallest peak bending radius. The smaller value of peak bending radius allows MCF to bend into smaller radius. Therefore, Configuration 1 is the potential choice for the design of MCF with smaller peak bending radius and ultra-low crosstalk level compared to the other configurations of SI-heterogeneous MCF.

Brand Product

In this paper, the authors investigate the impact of in-store promotion and its spillover effect on private label introductions. Studying different retail supply chain scenarios in which the retailer carrying a national brand may introduce its own private label product and promote either the national brand or the private label inside the store, they find the in-store promotion on one product has a positive spillover effect on the other product. Without in-store promotion and spillover effect, the conventional wisdom indicates that, in a retail supply chain, the national brand manufacturer will be negatively affected by the introduction of a private label product. With in-store promotion and spillover effect, however, the national brand manufacturer can actually benefit from the private label introduction. When the spillover from national brand to private label is high, the retailer prefers to promote the national brand product. When the spillover from private label to national brand is high, promoting the private label product can also benefit the national brand manufacturer. With a symmetric spillover rate, the national brand manufacturer can still benefit from the private label introduction, as long as the retailer promotes the national brand product, the horizontal competition is not intense, or the private label product quality is sufficiently low.

In today's world where the importance of digitalization is increasing day by day, companies to increase their competitiveness have focused on digital supply chain instead of traditional supply chain. In a world where resources are constantly decreasing, the concept of sustainability has become very crucial in every part of life. Digital technologies, on the other hand, have a direct relationship with sustainability. Sustainability has three main dimensions: economic, environmental, and social. Therefore, the aim of this study is to evaluate digital supply chain on 3 basic dimensions of sustainability. For this purpose, Fuzzy Best Worst Method (F-BWM) was used to define the importance level of criteria. Findings reveal that the concept of sustainability in textile firms in Turkey is generally perceived within an economic and environmental area, rather than within a social dimension. This study is very important in putting forward digital technologies which utilizing in supply chain and the impact of the digital supply chain on sustainability.

The main purpose of this paper is to develop a framework for utilization of lean, agile, and leagile strategies in the supply chains, where the core idea of the framework is to improve the global sourcing practices. Based on in-depth interviews with supply chain professionals and grounded theory approach, we constructed a framework of global sourcing improvement to support better utilization of lean, agile, and leagile strategies, which we believe can help the supply chains worldwide to act better, especially in various difficult conditions and sustain their business accordingly. Our proposed framework also contributes to the UN’s Sustainable Development Goals, since the core concept of the framework is to establish a new organization under the umbrella of the UN to improve the global sourcing and consequently the usage of supply chain strategies accordingly. The applicative part of the paper reveals characteristics of new developed framework, ranging from its purpose and aims, structure, key processes, functions, and its financing. Along with validation of the framework are presented benefits for society, industry, and global economy. Additionally, the paper also reviews the impact of the current health and economic crisis caused by COVID 19, on usage of the three supply chain strategies namely; lean, agility, and leagility to see how they can work in the difficult time, as COVID 19.

In current large-scale supply chain networks, unexpected disruptions degrade the supply availability and network connectivity for modern enterprises. How to improve the robustness of supply chain networks is very important for modern enterprises. In this paper, we explore how to improve the robustness of supply chain networks from a topological perspective. Firstly, through the empirical data-driven study, we show that the directed betweenness metric is more suitable than the other topological metrics in evaluating the robustness of supply chain networks. Then, we propose a rewiring algorithm based on directed betweenness to improve network robustness under the impact of disruptions. The experimental results in the large-scale supply chain network show that the rewiring algorithm based on directed betweenness effectively improves the network robustness.

Purpose The purpose of this paper is to study the impact of bargaining powers of firms in supply chain coordination. It studies selected aspects of bargaining powers, namely, impatience, breakdown probability and outside options, and uses a bargaining-theoretic approach to analyze surplus allocation in a coordinated supply chain. Design/methodology/approach This paper proposes one-supplier one-buyer infinite horizon supply chain coordination game, where suppliers and buyers negotiate for the allocation of supply chain surplus arising out of supply chain coordination. Various aspects of the bargaining power of the negotiating parties are modeled and the paper studies impact of power levels on the results of the bargaining game. Findings A significance of impatience on the bargaining process and the surplus split has been established. This paper also demonstrates a rather counter-intuitive aspect of bargaining that the impatience (as perceived by the other party) can improve the bargaining position and therefore share of profits. Research limitations/implications This paper has limited its analysis to three key components of bargaining power. Future works can study other aspects of bargaining power, namely information asymmetry, learning curve, inside options, etc. Further, the paper has considered an infinite horizon model – this assumption can be relaxed in future research. Practical implications Equations to derive optimal split of the surplus have been derived and can be leveraged to design an autonomous bargaining agent to discover equilibrium profit splits in a cloud or e-commerce setting. Further, insights from this paper can be leveraged by managers to understand their relative bargaining power and drive to obtain the best profit split. Originality/value This paper establishes that impatience (in terms of counter-offer probability) has a significant impact on the bargaining position and on the split of the surplus that the firm can get for themselves. It establishes the advantage of higher levels of impatience, provided the other party recognizes the impatience and factors it in their decision-making process.

Helping And Hindering Factors

This article was written to honour the memory of Roger Grainger, particularly his contribution to the dialogue between (drama)therapy and religion. As authors from two different faith backgrounds, who work with clients of many and no faiths, we research the impact of working with religion in therapy, its potentially helping and hindering factors. In the context of PREVENT, a government strategy aiming to protect people from terrorism ( https://www.gov.uk/government/publications/prevent-strategy-2011 ), faith can be associated with radicalisation combined with a traditional distrust of therapy towards religion. This might lead us to shy away from this area. On the other hand The British Association of Dramatherapists' Intercultural good practice guidelines advocate working within a client's cultural, thus also religious background. The following argument discusses the core concepts we are working with, outlines Roger's contribution, contextualises them within current debates and raises the challenges we face. We hope the debate will be developed by fellow dramatherapists so that our fluency in interreligious practice will continue to improve.

Corporate Distress

PurposeThe aim of the study is to provide evidence on the distress in the supply chain and its impact on the trade credit policy, firms’ performance and risk and their growth opportunities. Trade credit creates a strict relation between suppliers and customers that cannot be easily substituted over time. The linkages established between firms in a supply chain are a key value added for all members that could represent a competitive advantage over independent market players. In the event of a supply chain disruption, all members could suffer from a decrease in profitability and an increase in risk. Nonetheless, no empirical evidence exists on the expected economic and financial effects on pertinent suppliers and customers.Design/methodology/approachThis paper examines the US market and evaluates the impact of a supply chain member’s default on the other members, looking at both the customers’ and suppliers’ default. The sample considers all firms in the USA disclosing entry into bankruptcy proceedings through EDGAR filings that were not classified as financial intermediaries between 2012 and 2016. The analysis considers the effect of distress on the supply chain (suppliers or customers) on the trade credit policy, performance, risk and growth perspectives of connected firms.FindingsThe results show that a supply chain disruption not only modifies the trade credit policy but also affects firm risk and profitability and the financing sources available to support firm growth. Empirical evidence shows that the bankruptcy of a member of the supply chain affects the trade credit policy of all the other members. The costs related to default are economically and financially relevant to all supply chain members and affect the resiliency of the supply chain beyond the short term.Originality/valueThis paper uses an original and innovative database to empirically test the impact of corporate distress on supply chain financing, performance, risk and growth opportunities.

Learning English

The competency of English among future graduates has consistently been discussed and has become a national concern. The impact of not having competency in English contributes to the hindrance of communication. Thus, English language becomes a major factor graduates are not able to secure suitable employment or to perform at work. The Technical and Vocational Education Training providers such as polytechnics share the same concern as the other institutions. English courses are taught as compulsory course for all students and students are given opportunities to practise the language through co-curricular activities. Communicative English is offered in three semesters, to support the core subjects and complement the technical subjects. In leading towards development and preparing graduates to meet the needs of the future, it is pertinent to ensure that the outcome of English courses in polytechnics is to produce graduates with adequate language competency and ready for work. This chapter reveals the challenges faced by English and content lecturers based on teaching English in polytechnics, teaching the discipline content in English and the collaboration between both subject lecturers. Qualitative data is gathered based on interviews with the lecturers to discover the perception of lecturers from language and content disciplines. The challenges in teaching and learning English are analysed and recommendations for improvement are beneficial to be used as interventions to improve the teaching and learning of English in polytechnics.
