Traditionally, industrial power supplies have been exclusively controlled through analog control to sustain high reliability with low cost. However, with the perpetual decrement in cost of digital controllers, the feasibility of a digitally controlled switch mode power supply has elevated significantly. This paper aims to outline the challenges related to the design of digital proportional-integral (PI) controlled synchronous rectifier (SR) buck converter by comparing controller performance in continuous and discrete time. The trapezoidal approximation-based digital PI control is designed for low voltage and high-frequency SR buck converter operating under continuous conduction mode.

The analog and digital controller are designed using a SISO tool of MATLAB. Here, zero-order hold transform is used to convert the transfer function from continuous to discrete time. Frequency and time domain analysis of continuous plant, discrete plant and close loop system is performed. The designed digital PI control is simulated in MATLAB Simulink. The simulated results is also verified on hardware designed around digital signal processing control.

The continuous and discrete control loops are validated with multiple tests in the time and frequency domain. The detailed steady state theoretical analysis and performance of the SR buck converter is presented and verified by simulation. It is found that the delay in digital control loop results in a low phase margin. This phase margin decreases with higher bandwidth. The hardware experiments with the digital control loop are carried out on a 10 W prototype. The chosen parameters for the SR buck converter are found to be optimum for steady and transient state response.

This paper compares the digital and analog control approach of compensator design. It focuses on the implications created at the time of transforming the control design from continuous to discrete time. Further, it also focuses on the selection of parameters such as phase margin, bandwidth and low pass filter.

This study examines the connection between different digital-twin characteristics and organizational control. Specifically, the study aims to examine whether the digital-twin characteristics exploration, guidance and gamification will affect formal and social control.

The study is based on an analysis of survey results from 139 respondents comprising applied university students who use digital twins.

The results offer an interesting contribution to the literature. The authors consider the digital-twin characteristics exploration, guidance and gamification and investigate their contribution to two types of organizational controls: formal and social. The results show that two characteristics, exploration and gamification, affect the extent to which digital twins can be utilized for social control. Exploration and guidance’s role is significant concerning the extent to which digital twins can be utilized for formal control.

This study contributes to literature by considering multiple digital-twin characteristics and their contribution to two different control outcomes. First, it diverges from previous technical-oriented research by investigating digital twins in a human context. Second, the study is the first to examine digital twins’ effects from an organizational control perspective systematically.

Value-based selling (VBS) is increasingly a key success factor in business to business (B2B) settings, but its relationship with digital solutions selling (DSS) has not been explored. This study aims to develop a motivation-opportunity-ability (MOA)-based model that shows how an individual salesperson’s task-specific motivation to implement DSS affects personal capabilities to engage in DSS-related internal coordination, customer networking and ultimately VBS behavior. The authors also account for the supervisor’s DSS-focused behavioral control as the opportunity variable, potentially influencing all other variables in the framework.

The authors test the model and hypotheses using data of 178 salespeople from a B2B company growing its digital solutions business. Path modeling and SmartPLS software are used to estimate the model.

The results demonstrate the key importance of DSS implementation motivation to implement VBS. The findings emphasize the mediating role of salespeople’s ability to collaborate with colleagues and engage in customer networking to configure the right idiosyncratic digital solutions and demonstrate these solutions’ economic value. Supervisors have a fundamental role in directly and indirectly stimulating DSS motivation, DSS-related customer networking ability and VBS.

The study has several limitations. The authors examined a single company. In addition to internal coordination and customer networking, other relevant abilities of salespeople could be considered as mediators between DSS and VBS. Similarly, other opportunity factors may be analyzed in the future, such as supervisors’ risk orientation and ability to stimulate team spirit. Future research could also investigate other salespeople’s individual talents and additional organizational support variables that predict a salesperson’s behavioral and outcome performance in DSS and VBS.

Companies willing to adopt VBS should acquire, develop and retain salespeople characterized by strong motivation to implement DSS. Supervisors should adopt a DSS-focused behavioral control, and companies should support supervisors through appropriate training on how to manage detailed feedback to salespeople constructively and sales performance management systems that systematically track DSS-related sales force activities and results. Companies should also facilitate DSS-related teamwork, for example, through team incentives, and DSS-related customer networking, for instance, through appropriate sales enablement platforms and tools.

The research addresses the communalities and differences between solutions selling and VBS, suggesting a causal relationship. While prior research has analyzed solutions and value mainly as corporate strategies at the organizational level, the current study considers implementation at the individual salesperson level. The study focuses on digital solutions, which are more uncertain and complex to sell than traditional solutions.

Digital transformation and innovation-driven development have become an international consensus. The purpose of this paper is to examine the effects of relationships, mechanisms and economic consequences between digital transformation and enterprise innovation quality in order to provide a benchmark for developing countries to implement digital transformation strategies and innovation-driven strategies and provide a major support for economic recovery in the post-coronavirus disease 2019 (COVID-19) era.

Using microdata from A-share listed enterprises in Shanghai and Shenzhen from 2010 to 2021, this study examines the relationship between digital transformation and enterprise innovation quality and further reveals the internal logic and economic consequences of digital transformation to improve enterprise innovation quality through the mediating effect and moderating effect models.

The results demonstrate that digital transformation is beneficial for improving enterprise innovation quality. The heterogeneity test demonstrates that digital transformation has a larger effect on improving enterprise innovation quality in non-state-owned enterprises and eastern enterprises in China. The mechanism test demonstrates that digital transformation can improve enterprise innovation quality by improving internal control quality and analyst attention. Furthermore, with the increase in enterprise innovation inputs, digital transformation plays a significantly stronger role in improving enterprise innovation quality. The extended analysis demonstrates that digital transformation can significantly improve enterprise financial performance by improving innovation quality.

First, the construction of the core explanatory variable digital transformation index in this study is based on the Python data analysis software, which calculates the frequency of digital transformation in the text of the business situation analysis portion of the annual report of the listed companies and then obtains the degree of digital transformation of the company in this year. There may be some deviation from the degree of digital transformation in the actual production and operation of enterprises. Second, in addition to internal control quality and analyst attention, are there other mediating mechanisms for the impact of digital transformation on the quality of enterprise innovation? Third, whether the moderating effect of innovation input on digital transformation and innovation quality is related to human capital factors of the research and development (R&D) team, such as the technical background of R&D personnel, etc.

This study enriches the relevant theories of digital transformation and broadens the research boundaries of digital transformation and enterprise innovation. This study's result provides an empirical basis for enterprises to improve enterprise innovation quality and financial performance from the perspective of digital transformation at the micro level and points out specific practical directions, combining theory with practice.

Technology increasingly features in intimate relationships and is used by domestic violence perpetrators to enact harm. In this chapter, we propose a theoretical and practical framework for technology-facilitated harms in heterosexual relationships which we characterize as digital coercive control. Here, we include behaviors which can be classified as abuse and stalking and also individualized tactics which are less easy to categorize, but evoke fear and restrict the freedoms of a particular woman. Drawing on their knowledge of a victim/survivor's experiences and, in the context of patterns and dynamics of abuse, digital coercive control strategies are personalized by perpetrators and extend and exacerbate “real-world” violence.

Digital coercive control is unique because of its spacelessness and the ease, speed, and identity-shielding which technology affords. Victim/survivors describe how perpetrator use of technology creates a sense of omnipresence and omnipotence which can deter women from exiting violent relationships and weakens the (already tenuous) notion that abuse can be “escaped.” We contend that the ways that digital coercive control shifts temporal and geographic boundaries warrant attention. However, spatiality more broadly cannot be overlooked. The place and shape in which victim/survivors and perpetrators reside will shape both experiences of and response to violence. In this chapter, we explore these ideas, reporting on findings from a study on digital coercive control in regional, rural, and remote Australia. We adopt a feminist research methodology in regard to our ethos, research processes, analysis, and the outputs and outcomes of our project. Women's voices are foreground in this approach and the emphasis is on how research can be used to inform, guide, and develop responses to domestic violence.

The purpose of this study is to investigate whether the corporate environmental, social and governance (ESG) performance of enterprise is influenced by the enterprise digital transformation. In addition, this study explains how enterprise digital transformation affects ESG performance.

The sample covers 4,646 nonfinancial companies listed on China’s A-share market from 2009 to 2021. The study adopts the fixed-effects multiple linear regression to perform the data analysis.

The study finds that enterprise digital transformation has a significant inverted U-shaped impact on ESG performance. Moderate digital transformation can improve enterprise ESG performance, whereas excessive digital transformation will bring new organizational conflicts and increase enterprise costs, which is detrimental to ESG performance. This inverted U-shaped effect is more pronounced in industrial cities, manufacturing industries and enterprises with less financing constraints and executives with financial backgrounds. Enterprise digital transformation mainly affects ESG performance by affecting the level of internal information communication and disclosure, the level of internal control and the principal-agent cost.

The government should take multiple measures to encourage enterprises to choose appropriate digital transformation based on their own production behaviors and development strategies, encourage them to innovate and upgrade their organizational management and development models in conjunction with digital transformation and guide them to use digital technology to improve ESG performance.

This study shows that irrational digital transformation cannot effectively improve the ESG performance of enterprises and promote the sustainable development of the country. Enterprises should carry out reasonable digital transformation according to their own development needs and finally improve the green and sustainable development ability of enterprises and promote the sustainable development of society.

This study examines the relationship between enterprise digital transformation and ESG performance. Different from the linear relationship between the two in previous major studies, this study proves the inverse U-shaped relationship between enterprise digital transformation and ESG performance through mathematical theoretical model derivation and empirical test. This study also explores in detail how corporate digital transformation affects ESG performance, as well as discusses heterogeneity at the city, industry and firm levels. It is proposed that enterprises should take into account their own characteristics and carry out reasonable digital transformation according to their development needs.

Using the lens of Uber’s digital workers in Paris, the purpose of this paper is to investigate how the trust-building mechanism is constructed between a digital platform and its digital workers in a foreign market entry.

This is a case study based on empirical data from in-depth interviews with 35 Uber drivers. A cross-disciplinary literature framework from mainly international business and internet geography theory and a reflexive qualitative methodology are applied.

Results show that the relationship between the digital platform and the digital workers is characterized by mistrust and suffers from decreasing commitment levels soon after market entry. Uber mitigates its mistrust via control and scarce mechanisms. The digital drivers’ “illusionary freedom”, a state in which they feel they can log on and log off at any time, enables the digital platform to gradually lower its commitment. The authors find that the mistrust does not seem to hamper the digital platform’s business performance.

The paper mainly covers the digital workers’ perspective and the case of Uber’s market entry in Paris.

This paper implies that digitally conveyed control seems to come at the cost of lowered human trust. Given the pace at which digital control systems are permeating society, this could eventually lower the whole societal trust level.

The authors criticize incumbent international business theory for not being sufficiently able to explain a contemporary digital business logic and the authors challenge the general assumption that successful internationalization is built through trust. The authors contribute with the conceptualization of a new technical market entry mode for digital platforms – “digitally controlled proxies”.

Digital solutions (DS) that build on recurring revenue models (RRMs) offer new opportunities to continuously create and capture superior value. However, many firms fail to engage their sales force in digital solution selling (DS selling), leading to agency problems that receive little attention in literature. This study aims to examine the drivers of agency problems that surface in the transition toward DS selling and the sales control systems that resolve these problems.

The authors conducted a qualitative, inductive study. Data were collected from interviews with 72 marketing and sales managers representing 53 industrial firms transitioning toward DS selling.

DS selling is subject to adverse selection and moral hazard caused by motivation-related, opportunity-related and ability-related drivers. Input, capability, activity and outcome controls – detailed in this study – can resolve these agency problems.

The limitations of this study’s methodology and scope suggest several directions for future research. Methodology-wise, the authors mainly relied on cross-sectional interview data from informants in Central and Northern Europe. Scope-wise, more research is needed on the capabilities, processes and steering instruments supporting DS sales. Finally, only now do the authors begin to understand which compensation plans motivate DS selling.

The controls identified in this study help managers to steer their sales force in DS sales.

To the best of the authors’ knowledge, this study is the first to investigate DS sales control systems. Thereby, the authors enhance prior understandings of solution selling, agency problems and sales control systems.

Under such circumstances, how to assign the highest priority for future products which will create the greatest value will be the key success factor for a product planning model. The purpose of this study is to construct an improved planning model for new products based on the theoretical structures of technology roadmaps and patent analysis.

This study takes the perspective of a product planning strategy, using technology roadmap developed by Institute of Manufacturing Technology of the University of Cambridge, combining with scenario planning and patent analysis. The main body of the proposed model is the technology roadmap of the product. Through patent analysis, the technology roadmap was integrated into the hierarchical execution of product planning to improve the disadvantages of the original technology roadmap and thereby clarify the content of the implemented procedure. With the planning of digital home products in a large household appliance manufacturer in China as a case study, the feasibility of the proposed model was verified.

The improved planning model for new products comprised five planning phases: market scenario planning, product feature analysis, technological development analysis, patent combination analysis, and resource allocation. A matrix corresponding to product planning was established. The case study is to find out the developing trends in next‐generation product features in six different scenarios of digital home for M, a home appliance manufacturer. There are five steps of the product planning model. The product planning model provides enterprises with integrated information from market demand, technology as well as patents. At the same time, it is easy to maintain and reproduce. The authors expect the model to make a contribution to practical product planning.

This model should become an essential prediction tool for enterprises developing new products and can assist in decision‐making and strategic implementation.

This paper attempts to explain the wide dissemination of Library of Congress Subject Headings (LCSH) within digital libraries and presents some of the advantages and disadvantages of using this controlled vocabulary in digital collections. The paper also presents other classifications used in digital collections for subject access and explores ways of improving search functionality in digital collections that employ LCSH.

Unlike traditional libraries that use Library of Congress Classification for organization and retrieval, digital libraries use metadata forms for organization and retrieval. The collections exist in cyberspace of the internet which is known for containing the universe of knowledge. The use of LCSH for information retrieval has been widely criticized for its difficulty of use and its information retrieval effectiveness in online environments. The Library of Congress (LOC) has claimed the headings were not based on comprehensive principles nor ever intended to cover the universe of knowledge. Despite these claims and criticisms, LCSH is the most popular choice for subject access in digital libraries.

The number of digital collections increases every year and LCSH is still the most popular choice of controlled vocabulary for subject access. Of the numerous criticisms, difficulties of use and user unfamiliarity are the greatest disadvantages of using LCSH for subject access. Average users only have a vague notion of what they are looking for when initializing a search. More work is required in automated generation of subject headings and increased usage of LCSH in faceted search retrieval systems. This will provide users with better access to the LCSH used in the back end of information retrieval.

The Greek researchers who developed the Dissertation DSPace system believe this type of module will eventually replace the traditional keyword‐based indexing back ends employed by many information retrieval modules within current digital library systems. The system offers the type of access and interactivity that will acquaint users with how LCSH looks and is used. Faceted search and automated pattern matching using an ontology based on LCSH have the best promise of overcoming the disadvantages that have always plagued the LOC‐controlled vocabulary. These retrieval techniques give LCSH an opportunity to finally achieve the optimal precision and recall it has so far failed to deliver.
