The purpose of this paper is to introduce new non‐classical implementations of neural networks (NNs). The developed implementations are performed in the quantum, nano, and optical domains to perform the required neural computing. The various implementations of the new NNs utilizing the introduced architectures are presented, and their extensions for the utilization in the non‐classical neural‐systolic networks are also introduced.

The introduced neural circuits utilize recent findings in the quantum, nano, and optical fields to implement the functionality of the basic NN. This includes the techniques of many‐valued quantum computing (MVQC), carbon nanotubes (CNT), and linear optics. The extensions of implementations to non‐classical neural‐systolic networks using the introduced neural‐systolic architectures are also presented.

Novel NN implementations are introduced in this paper. NN implementation using the general scheme of MVQC is presented. The proposed method uses the many‐valued quantum orthonormal computational basis states to implement such computations. Physical implementation of quantum computing (QC) is performed by controlling the potential to yield specific wavefunction as a result of solving the Schrödinger equation that governs the dynamics in the quantum domain. The CNT‐based implementation of logic NNs is also introduced. New implementations of logic NNs are also introduced that utilize new linear optical circuits which use coherent light beams to perform the functionality of the basic logic multiplexer by utilizing the properties of frequency, polarization, and incident angle. The implementations of non‐classical neural‐systolic networks using the introduced quantum, nano, and optical neural architectures are also presented.

The introduced NN implementations form new important directions in the NN realizations using the newly emerging technologies. Since the new quantum and optical implementations have the advantages of very high‐speed and low‐power consumption, and the nano implementation exists in very compact space where CNT‐based field effect transistor switches reliably using much less power than a silicon‐based device, the introduced implementations for non‐classical neural computation are new and interesting for the design in future technologies that require the optimal design specifications of super‐high speed, minimum power consumption, and minimum size, such as in low‐power control of autonomous robots, adiabatic low‐power very‐large‐scale integration circuit design for signal processing applications, QC, and nanotechnology.

The emergence of digital transformation in the banking industry gives rise to the challenges of adopting technology and boosting users' confidence in the process. This study mainly explores the roles of operant resources and consumption values in the user's consumption process concerning the fintech-embedded product-service system (FPSS) that provides technologically advanced financial services in South Korea.

This study examines the research model based on users' perceived quality, assessment and recommendation of FPSS. In addition, grounded in the resource-based view (RBV) and consumption value theory (CVT), an extended model is developed to understand the impact of user consumption value on FPSS design. The research model includes both product-service system (PSS) characteristics, i.e. quality and assessment, and user-specific characteristics, i.e. conditional, utilitarian and social values (collectively referred to as user consumption value).

This study finds that information, service and security quality positively affect users' confidence through positive assessment and recommendation intention. All the elements of user consumption value play a positive role in the FPSS user confidence model. In addition, the impact of operant resources on the overall service assessment is further investigated based on the interest of user's service engagement. Notable findings include users that highly engage in FPSS services return higher service assessment when social value, information quality and service quality increase.

Overall, this study provides academic and managerial guidelines for the strategic design of fintech-embedded banking services by considering the roles of PSS and user-specific characteristics in fostering sustainable competitive advantage.

This study aims to use computational fluid dynamics (CFD) to understand and quantify the overall blockage within a transonic axial flow compressor (AFC), and to develop an efficient collaborative design optimization method for compressor aerodynamic performance and stability in conjunction with a surrogate-assisted optimization technique.

A quantification method for the overall blockage is developed to integrate the effect of regional blockages on compressor aerodynamic stability and performance. A well-defined overall blockage factor combined with efficiency drives the optimizer to seek the optimum blade designs with both high efficiency and wide-range stability. An adaptive Kriging-based optimization technique is adopted to efficiently search for Pareto front solutions. Steady and unsteady numerical simulations are used for the performance and flow field analysis of the datum and optimum designs.

The proposed method not only remarkably improves the compressor efficiency but also significantly enhances the compressor operating stability with fewer CFD calls. These achievements are mainly attributed to the improvement of specific flow behaviors oriented by the objectives, including the attenuation of the shock and weakening of the tip leakage flow/shock interaction intensity.

CFD-based design optimization of AFC is inherently time-consuming, which becomes even trickier when optimizing aerodynamic stability since the stall margin relies on a complete simulation of the performance curve. The proposed method could be a good solution to the collaborative design optimization of aerodynamic performance and stability for transonic AFC.

This paper aims to explore how leaders can develop value-based leadership for sustainable quality development in Lean manufacturing.

A qualitative meta-analysis was conducted using data from a three-year study of Lean manufacturing in Sweden using the Shingo business excellence model as an analytical framework.

This study demonstrates that leaders can develop value-based leadership to support Lean manufacturing by defining and articulating the organization’s values and accompanying behaviors that are needed to support the strategic direction; creating forums and time for leaders to identify the why behind decisions and reflect on their experiences to be able to lead a transformative process; and using storytelling to create a coaching culture to connect values and behaviors, to the processes and systems of work.

This paper contributes insights for developing value-based leadership to support a systemic approach to sustainable quality development in lean manufacturing. Findings are based on a limited case sample size of three manufacturing companies in Sweden.

The findings were derived using a unique methodological approach combining storytelling, appreciative inquiry and coaching with traditional data collection methods including surveys and interviews to identify, define and shape value-based leadership in Lean manufacturing.

This paper seeks to examine the influence of pricing orientation on the price‐setting process in industrial firms.

The authors designed a qualitative inquiry based on the principles of grounded theory with 44 managers in 15 industrial firms located across ten US states. These managers included CEOs, pricing and marketing professionals, and financial professionals working in three industries (automotive, building products and chemicals).

The study's results reflect similarities and differences in the experiences of managers in industrial firms using all three pricing orientations. It reveals stark contrasts by pricing orientation with respect to how firms organize for pricing, manage the pricing process, make product pricing decisions, manage the transition to more advanced pricing orientations, and develop internal capabilities to face uncertain and ambiguous decisions. The findings also uncover contrasting price‐setting processes by pricing orientation and the balanced used of scientific versus intuitive decision‐making processes.

Pricing is often a neglected element of the industrial marketing mix. This study offers a variety of organizational practices by pricing orientation. The results highlight how best‐in‐class companies that adopted modern pricing practices to derive product prices are organized and how they reach pricing decisions.

This study studies the commonly accepted pricing orientations and links them to organizational structure and decision‐making theory. This study contributes to bridging pricing and organizational theories.

This paper aims to explore consumer perceptions of product design awards (PDAs) and their impact on consumer product evaluation and attitude formation about the award-winning product, the award-winning organization and the award-granting organization.

Based on the grounded theory approach, an exploratory qualitative study is conducted, using 16 semi-structured in-depth interviews with Turkish consumers through discussions on real-world examples.

Results show that consumers develop emotional responses to PDAs (e.g. interest, curiosity and confusion), hypothesize reasons for products receiving awards and cite rewards as confirmation of their existing judgments about products. PDAs are perceived as extrinsic cues signaling quality and price, and their impact is increased when consumers feel that the award is based on functional feature superiority. Consumer responses to PDAs are also influenced by the perceived expertise of the award-granting organization and beliefs about the award-granting process. Finally, PDAs can lead to positive brand-perception outcomes, influencing consumer perceptions of the product company as resourceful, competent and prominent.

This study shows that it is critical for companies to inform consumers about the specific features that resulted in a given product receiving a design award, as well as to provide information about the PDA itself.

To the best of the authors’ knowledge, this study is the first attempt to explore consumer perceptions of and reactions to PDAs, with significant implications for both the marketing managers of PDA-winning products and award-granting organizations.

The purpose of the research is to utilize and expand on existing knowledge on organizational value‐based innovativeness, towards the development of the “strategic reflexivity” concept, for businesses competing in the contemporary ever‐modulating business environments.

The paper is based partly on primary qualitative research and partly on theoretical research. The former consists of a six month long in‐house observation and data gathering of a large company (OPERACOM Group) innovation process and on 45 semi‐directive interviews of practitioners and experts.

The findings descriptively portray the varying competitive conditions as intolerant of conventional strategic marketing planning; and unable to sustain any lasting competitive advantage. Prescriptively, the research proposes a change of strategic philosophy and practice, through a shift from orthodox planning to the design of value‐based reflexive mechanisms that automatically adapt to change. The paper finally presents a preliminary model for the proposed strategic reflexivity process.

The paper, though scientific, it is in parallel a conceptual one. The “strategic reflexivity” concept and its consequent model therefore, are presented, not as a definitive answer to the concerns of contemporary businesses; but rather as a scientifically‐based proposition towards further practical and scholarly development.

The research value rests on a tripod of original contributions: it adds to the voices calling executives to give up on conventional tactical strategic means, counter‐proposing strategic redevelopment that is explicitly value‐based; it identifies the value‐based innovational elements deemed critical in the strategic redevelopment of businesses in hypercompetitive environments; and it develops the “strategic reflexivity” concept and process within the above context towards theoretical development and practical implementation.

This paper appropriates the value sensitive design (VSD) framework to examine the role of design values in the development of an information system designed to increase transparency and reduce corruption within the context of a large‐scale e‐governance project in India.

A qualitative case study was conducted and data were collected through interviews with system designers, observations of system design and implementation, and walk‐through of designed systems. Data analysis followed an interpretive approach intended to understand informants' meaning‐making. Analysis occurred iteratively both during and after the field study.

The study reveals the complexity of the role of values in the design of information technology wherein the designers in their pursuit of transparency and reduced corruption have to continuously balance their idealistic and pragmatic values.

This study tests the VSD framework in the context of developing an e‐government system thereby highlighting its usefulness but also outlining ways in which the framework can be expanded to make it more relevant to diverse contexts.

This study extends the VSD framework, particularly in contexts where designers' values are primary drivers of design decisions. A greater understanding of the role of design values across the design process can prove crucial in inculcating and reinforcing design values that lead to a more contextually relevant product.

This research provides valuable lessons on how to approach design of systems that can benefit humans with implications for designers and for public policy.

This is one of the first studies that utilizes the VSD framework to study information system design in a human development context with novel implications for both research and practice.

This study aimed to examine the digital transformation of business-to-business (B2B) sales and its effects on the management of value-based selling.

The study adopted a qualitative interview research design. A total of two participant groups—one consisting of sales management professionals and the other consisting of buyers—were created to conduct abductive data analysis to gain a new understanding of B2B sales management.

As a result of the digital transformation of sales, companies are shifting B2B sales towards value-based selling using a more proactive, continuous process wherein digital value co-creation activities play a big role. Similarly, their buyers now expect more proactive communication about new value propositions, but social media channels are of little importance to most B2B buyers. The management of digital value co-creation activities should be addressed from the sales ecosystem perspective, where non-sellers tend to have a strong role in communicating new value propositions.

There needs to be further research on digital value co-creation activities in the sales ecosystem, as value-based selling requires that selling organizations focus more on educational digital content marketing and engagement with non-sellers via both marketing and sales activities.

Companies rarely exploit experts and project personnel when implementing digital sales strategies; however, they often meet with customers personally and network with them. This requires a broader perspective on sales management.

This is one of the first studies to explore the management of value-based selling from both seller and buyer perspectives.
