Purpose Recent technological advances in three-dimensional printing (3DP) may disrupt traditional manufacturing and logistics processes. Because the increasing availability of 3DP service centers, affordable 3D printers, and online platforms empower consumers to design and print objects at home, companies must determine the motives that lead consumers to become prosumers so that they can establish appropriate business models and supply chains. Accordingly, the purpose of this paper is to identify factors that drive consumer acceptance and use of 3DP technologies. Design/methodology/approach The explanatory conceptual framework, based on the extended unified theory of acceptance and use of technology, undergoes empirical testing with a sample of 196 3DP consumers who participated in an online survey. Findings Facilitating conditions, hedonic motivation and a do-it-yourself mentality are key determinants of consumer acceptance and use intention of 3DP technology. Practical implications Companies can use these insights about consumers’ motivation to determine whether their use of 3DP technology threatens current business models or supply chains. In turn, they can develop new ideas about how to adapt these features, as well as identify opportunities for new revenue streams. Originality/value Unlike most extant literature on 3DP in manufacturing and logistics domains, this study takes consumers’ point of view to shed light on an issue typically investigated from an operations management perspective.

The Impact

Purpose While digitisation is a key driver of the fourth industrial revolution (Industry 4.0); organisations have different approaches to deal with this topic to get a clearer picture of the opportunities and challenges concerning the digital transformation. The purpose of this paper is to identify the impact of digitisation on procurement and its role within the area of supply chain management. The research will also explore potential barriers to digitising procurement and supply chains and ways to overcome them. Finally, the significance of potential enabling technologies to the digitisation will also be examined. Design/methodology/approach A quantitative approached utilising an online survey was used to collect the primary data for this study. Data were collected from 414 participants directly involved with procurement or related business functions and work for different organisations in different industries. The survey included eight items about the impact of digitisation on organisational performance in the area of procurement and supply chains; ten items related to key barriers to digitisation of organisations and ways to overcome them; and seven items about enabling technologies to leverage procurement procedures and processes digitisation. All of these items utilised the Likert five-point level of agreement scale. Findings The findings indicate that digitisation of procurement process can yield several benefits including: supporting daily business and administrative tasks, supporting complex decision-making processes, procurement will become more focussed on strategic decisions and activities, procurement will become a strategic interface to support organisational efficiency, effectiveness, and profitability, and supporting the creation of new business models, products, and services. The authors were also able to confirm that there are barriers to digitising procurement process and supply chains and such barriers found in existing procedures, processes, capacities, and capabilities. Finally, the significance of a number of enabling technologies to the digitisation process was revealed. Originality/value To the best of the authors’ knowledge, this is the first study of its kind with participants located world-wide. Industry 4.0 as a topic had been explored within different business areas and functions but very limited research specifically explored potential impact, barriers, and enabling technologies of procurement 4.0. The results can be beneficial for organisations already implemented Industry 4.0 or planning to do so. The study can also benefit academic scholars interested in the researched topic, business professionals, organisations within different sectors, and any other party interested in understanding more the concept of procurement 4.0.

Purpose The purpose of this paper is to present a comparison between reluctance synchronous machine-enabling work at high internal temperature (HT° machine) with laminated and solid rotor. Design/methodology/approach To obtain heat sources for the thermal model, calculations of the electromagnetic field were made using the Opera 3D program including effect of rotation and the resulting eddy current losses. To analyse the thermal phenomenon, the 3D coupled thermal-fluid (CFD) model is used. Findings The presented results show clearly that laminated construction is much better from a point of view of efficiency and temperature. However, solid construction can be interesting for high speed machines due to their mechanical robustness. Research limitations/implications The main problem, despite the use of parallel calculations, is the long calculation time. Practical implications The obtained simulation and experimental results show the possibility of building a machine operating at a much higher ambient temperature than it was previously produced for example in the vicinity of the aircraft turbines. Originality/value The paper presents the application of fully three-dimensional coupled electromagnetic and thermal analysis of new machine constructions designed for elevated temperature.

PurposeUsing online survey data from a sample of 440 police officers in California throughout May 2020, the current study collected time-sensitive information on officers' perceptions and departmental experiences in the wake of the pandemic. It examined officers' perceptions of agency responsivity as well as their perceptions of morale, stress and risk following agency responses and changes in policy patterns, service delivery innovations and other administrative challenges.Design/methodology/approachCOVID-19 had a tremendous impact on the law enforcement community, who continued to work and adapt in order to provide public safety. During the first few months of the pandemic, a number of national data collection efforts set out to understand what police agencies, at the organizational-level, were doing to address the crisis. Largely missing from these initial discussions were the perspectives of individual officers, particularly how they felt about their respective departments ensuring safety and balancing risk.FindingsResults from ordinary least squares (OLS) regressions found that the number of departmental changes made in the wake of COVID-19 that reduced police–public contact was associated with (1) increased levels of perceived agency responsivity to officer needs (i.e. balancing officer safety, taking active steps to maintain officers' mental health) and (2) reduced levels of perceived negative outlook (e.g. stress, low morale, danger/risk). Policy implications and the importance of police executives' decisions during crisis are discussed.Originality/valueThis study is one of the first, to the authors’ knowledge, to examine perceptions of policing during the pandemic from an individual officer point of view rather than an organizational standpoint.

Subjective Side

Purpose The purpose of this paper is to focus on the profile of DiDIYers and the antecedents of digital do it yourself (DiDIY) in Network Marketing Direct Selling Organizations (NMDSO). Design/methodology/approach A two-step research design allowed the detection of DiDIYers strictu sensu (i.e. digital makers). After collecting data about the attitudes and the actual use of digital technology (DT) by network marketers through an online survey, an open-ended interview technique made it possible to analyze the personal characteristics of DiDIYers, the motivations that drive them and the activities that mainly foster the creation of artifacts in the DT domain. Besides, it allowed to recognize the perceived benefits and the impact of DiDIY output on networkers’ downline and firms’ performance. Findings The results provide a preliminary profile of the DiDIYer in network marketing communities that is suitable for further comparative studies. More specifically, this exploratory study acknowledges the most important antecedents of DiDIY in digital literacy – including the awareness of being a digital literate and/or a potential appropriateur – and in organizational culture. Research limitations/implications This is an exploratory study based on a limited sample of DiDIYers, nevertheless it offers a preliminary view of the subjective side of the DiDIY phenomenon in network marketing and represents as well a context-bound study. Practical implications Considering the ascribed benefits of DiDIY output on the traditional network marketing objectives (effectiveness, efficiency, cohesion, mutual assistance and reinforcement) network marketing communities could benefit from an increase of attention to the topic. Originality/value The study throws light on the process of DiDIY within direct sales and network marketing activities by defining a preliminary profile of digital makers and thus, underlining a phenomenon neglected so far.

Purpose This paper aims to investigate the current state, technological challenges, economic opportunities and future directions in the growing “indirect” hybrid manufacturing ecosystem, which integrates traditional metal casting with the production of tooling via additive manufacturing (AM) process including three-dimensional sand printing (3DSP) and printed wax patterns. Design/methodology/approach A survey was conducted among 100 participants from foundries and AM service providers across the USA to understand the current adoption of AM in metal casting as a function of engineering specifications, production demand, volume and cost metrics. In addition, current technological and logistical challenges that are encountered by the foundries are identified to gather insight into the future direction of this evolving supply chain. Findings One of the major findings from this study is that hard tooling costs (i.e. patterns/core boxes) are the greatest challenge in low volume production for foundries. Hence, AM and 3DSP offer the greatest cost-benefit for these low volume production runs as it does not require the need for hard tooling to produce much higher profit premium castings. It is evident that there are major opportunities for the casting supply chain to benefit from an advanced digital ecosystem that seamlessly integrates AM and 3DSP into foundry operations. The critical challenges for adoption of 3DSP in current foundry operations are categorized into as follows: capital cost of the equipment, which cannot be justified due to limited demand for 3DSP molds/cores by casting buyers, transportation of 3DSP molds and cores, access to 3DSP, limited knowledge of 3DSP, limitations in current design tools to integrate 3DSP design principles and long lead times to acquire 3DSP molds/cores. Practical implications Based on the findings of this study, indirect hybrid metal AM supply chains, i.e. 3DSP metal casting supply chains is proposed, as 3DSP replaces traditional mold-making in the sand casting process flow, no/limited additional costs and resources would be required for qualification and certification of the cast parts made from three-dimensional printed sand molds. Access to 3DSP resources can be addressed by establishing a robust 3DSP metal casting supply chain, which will also enable existing foundries to rapidly acquire new 3DSP-related knowledge. Originality/value This original survey from 100 small and medium enterprises including foundries and AM service providers suggests that establishing 3DSP hubs around original equipment manufacturers as a shared resource to produce molds and cores would be beneficial. This provides traditional foundries means to continue mass production of castings using existing hard tooling while integrating 3DSP for new complex low volume parts, replacement parts, legacy parts and prototyping.

PurposeThis study aims to explore whether online learning has an effect on communication between instructors and students in a negative way, whether online learning affects students' productivity levels and to evaluate and suggest ways of improving effective online communication between instructors and students.Design/methodology/approachThis study used is a quantitative research study which was conducted through a semi-structured online survey through a random sample technique.FindingsResults revealed that the vast majority agree with the questions of the study. Students still prefer classroom classes over online classes due to many problems they face when taking online classes, such as lack of motivation, understanding of the material, decrease in communication levels between the students and their instructors and their feeling of isolation caused by online classes.Research limitations/implicationsThis research studied the impact from students' perspective only as the sample was selected only from students.Originality/valueThis research reached the students’ point of view in a broader way which will help understanding the issues and provide effective solutions. This research suggested that instructors must communicate with their students and vice versa in more informal channels (instant messages online chat groups, audio calls, private video calls …) in parallel with the formal channels (online platforms, email …). Finally, instructors should encourage students to participate and study more by providing different kind of incentives.

Closed Loop Supply Chains

Purpose The success of closed loop supply chains is contingent upon consumer acceptance of remanufactured products, yet little is known about how consumers value such products. The purpose of this paper is to provide theoretical grounding for understanding consumers’ value perceptions as related to remanufactured products. Design/methodology/approach Diffusion of innovation theory and customer perceived value literature help form the theoretical model, which is tested empirically using survey data of consumers. Structural equation modeling was employed to test the hypotheses. Findings Perceived value of remanufactured products is measured as a function of perceived benefits (environmental benefits; price advantage) and perceived sacrifices (perceived quality; perceived risk), all of which are shown to impact perceived value. Additionally, perceived risk is found to partially mediate the relationship between perceived quality and perceived value. Originality/value This research makes two significant contributions. First, mid-range theory that is contextualized to the closed loop supply chain is developed to aid researchers and practitioners in better understanding the consumer’s role in the closed loop supply chain, as related to the acceptance of remanufactured products. Second, consumer acceptance of remanufactured products represents a form of supply chain demand risk that has previously been unrecognized. The results provide a foundation for incorporating this type of demand risk in to future research efforts.

Purpose This paper aims to improve the service discipline’s understanding of the unique challenges and opportunities that services marketers encounter in Central, Eastern and Southeastern Europe (CESEE) and Post-Soviet states. This paper also serves as an introduction to the special section about services marketing perspectives in this region. Design/methodology/approach Considering the Post-Soviet reality, the paper is a viewpoint regarding the specific development potential of services marketing in the CESEE region. In addition, the three papers included in the special section use a variety of research methods, participants and service settings. Findings First, this paper outlines the positive and negative consequences of the radical changes in the services markets over the past 30 years. Next, all three papers included in the special section explore the distinctive customer perspective of services marketing. Finally, this paper discusses the specific relationship building environment of the Post-Soviet reality and how its unique do-it-yourself background contributes to the existing discussion on consumers’ involvement in the co-creation of value. Research limitations/implications The findings from this special section have valuable implications for future research on services marketing in the CESEE markets, although these may not always be generalizable beyond the unique context of the research detailed in each of these papers. Practical implications This research, along with the three papers, presents some useful directions for services marketing managers cooperating with the CESEE markets, such as understanding and managing the expectations of their customers or employees. Originality/value This paper is one of the first attempts to understand the uniqueness of the under-researched area of services marketing in the CESEE and Post-Soviet States, both from a theoretical and empirical point of view. This also provides previously under-represented authors from the region the opportunity to present their perspective to an international service community.
