Purpose The purpose of this paper is to describe how emerging open standards are replacing traditional industrial networks. Current industrial Ethernet networks are not interoperable; thus, limiting the potential capabilities for the Industrial Internet of Things (IIoT). There is no forthcoming new generation fieldbus standard to integrate into the IIoT and Industry 4.0 revolution. The open platform communications unified architecture (OPC UA) time-sensitive networking (TSN) is a potential vendor-independent successor technology for the factory network. The OPC UA is a data exchange standard for industrial communication, and TSN is an Institute of Electrical and Electronics Engineers standard for Ethernet that supports real-time behaviour. The merging of these open standard solutions can facilitate cross-vendor interoperability for Industry 4.0 and IIoT products. Design/methodology/approach A brief review of the history of the fieldbus standards is presented, which highlights the shortcomings for current industrial systems in meeting converged traffic solutions. An experimental system for the OPC UA TSN is described to demonstrate an approach to developing a three-layer factory network system with an emphasis on the field layer. Findings From the multitude of existing industrial network schemes, there is a convergence pathway in solutions based on TSN Ethernet and OPC UA. At the field level, basic timing measurements in this paper show that the OPC UA TSN can meet the basic critical timing requirements for a fieldbus network. Originality/value This paper uniquely focuses on the specific fieldbus standards elements of industrial networks evolution and traces the developments from the early history to the current developing integration in IIoT context.

Purpose The purpose of this paper is to understand the value creation mechanisms of open-standard inter-organizational information system (OSIOS), which is a key technology to achieve Industry 4.0. Specifically, this study investigates how the internal assimilation and external diffusion of OSIOS help manufactures facilitate process adaptability and alignment in supply chain network. Design/methodology/approach A survey instrument was designed and administrated to collect data for this research. Using three-stage least squares estimation, the authors empirically tested a number of hypothesized relationships based on a sample of 308 manufacturing firms in China. Findings The results of the study show that OSIOS can perform as value creation mechanisms to enable process adaptability and alignment. In addition, the impact of OSIOS internal assimilation is inversely U-shaped where the positive effect on process adaptability will become negative after an extremum point is reached. Originality/value This study contributes to the existing literature by providing insights on how OSIOS can improve supply chain integration and thus promote the achievement of industry 4.0. By revealing a U-shaped relationship between OSIOS assimilation and process adaptability, this study fills previous research gap by advancing the understanding on the value creation mechanisms of information systems deployment.

Discursive Constructions

Purpose This paper aims to propose an approach for exploring industrial marketing network environments through a social semiotic lens. Design/methodology/approach This conceptual paper introduces social semiotic perspectives to the study of business/industrial network interaction. Findings This paper describes how structures of meaning derived from a cultural history of signification and interpretive processes of meaning in action are co-determined in social semiosis. The meaning of environments using this social semiotic approach is emphasised, leading us to explore the idea of the “atmosemiosphere” – the most highly complex business network level, in illustrating how meaning is made through structuration between structures of meaning and their enactments in interactions between actors within living business networks. Practical Implications Figurative language plays an important role in the structuration of meaning. This facilitates establishing plots and, therefore, in the actors’ capability to tell a story, which starts with knowing what kind of story can be told. By implication, the effective networker must be a consummate moving “picture maker” and, to do so, she must have competence in narrative, emplotment, myth-making, storytelling and figuration in more than one discursive repertoire. Originality/value In using a structurational discourse perspective informed by social semiotics, our original contribution is a “business networks as discursive constructions” approach, in that discursive nets, webs of narratives and stories and labyrinths of tropes are considered just as important in constituting networks as networks of actor relationships and patterns of other activities and resources.

Advantages And Disadvantages

Continuing the evolution towards Industry 4.0, the industrial communication protocols represent a significant topic of interest, as real-time data exchange between multiple devices constitute the pillar of Industrial Internet of Things (IIoT) scenarios. Although the legacy protocols are still persistent in the industry, the transition was initiated by the key Industry 4.0 facilitating protocol, the Open Platform Communication Unified Architecture (OPC UA). OPC UA has to reach the envisioned applicability, and it therefore has to consider coexistence with other emerging real-time oriented protocols in the production lines. The Data Distribution Service (DDS) will certainly be present in future architectures in some areas as robots, co-bots, and compact units. The current paper proposes a solution to evaluate the real-time coexistence of OPC UA and DDS protocols, functioning in parallel and in a gateway context. The purpose is to confirm the compatibility and feasibility between the two protocols alongside a general definition of criteria and expectations from an architectural point of view, pointing out advantages and disadvantages in a neutral manner, shaping a comprehensive view of the possibilities. The researched architecture is meant to comply with both performance comparison scenarios and interaction scenarios over a gateway application. Considering the industrial tendencies, the developed solution is applied using non-ideal infrastructures to provide a more feasible and faster applicability in the production lines.

Purpose – The purpose of this paper is to present an overview of the history of heritage inventories in England and look at the requirements for a future vision of networked, digital heritage inventories to support heritage protection in England as outlined in the Heritage Information Access Strategy (HIAS). The strategy, led by Historic England, the UK Government-funded agency for heritage in England, is proposing a more formalized network where the prime sources of data relating to non-designated heritage assets will be the local authority historic environment records. Design/methodology/approach – This paper looks at the historic development of the inventories from paper-based publications to digital data sets and the proliferation of data. The Monument Inventory Data Standard Heritage will also be discussed in the context of providing a common framework. Findings – The present loose network presents several challenges for the multiple organizations maintaining similar data sets on disparate IT software, namely, the duplication of content, ownership of content and different approaches to recording practice and standards. There is a need for common data standards and controlled vocabularies in order to facilitate data exchange and interoperability across the network. Practical implications – The findings are based on the common experience of heritage inventory providers in England, but are relevant to any country where multiple inventories exist. It is anticipated that the implementation of the HIAS will provide a future-proofed environment for a shared national inventory. Originality/value – This paper presents the HIAS in its historic context. It is hoped that this may be of value to inventory programmes from outside the UK.

Purpose Industry 4.0 is the present trend in automation and data exchange in organizations. However, till today, there is no generic and common understanding in terms of assessing the Industry 4.0 readiness for organizations. The purpose of this paper is to identify the key ingredients for assessing Industry 4.0 readiness for organizations, the interrelationships that exist between these readiness factors and how future research should proceed given the research findings. Design/methodology/approach A systematic literature review (SLR) methodology of Tranfield et al. (2003) was employed to ensure the replicability and transparency of the review process. Altogether, 68 articles were identified for the final thematic analysis. Findings The SLR results generated six broad themes of readiness factors. The interrelationship mechanism between these factors was identified. In addition, 17 research propositions were elucidated. Research limitations/implications Being the first literature review on assessing Industry 4.0 readiness for organizations, it finds 17 research propositions which will give the future researchers a guideline for further research in Industry 4.0. Practical implications Although Industry 4.0 is the buzzword, very few organizations understand the concept in detail. This paper will help the organizations to identify the factors which they have to asses critically before implementing Industry 4.0 in an organization. Originality/value Nevertheless, there has been a lot of research on Industry 4.0; this is the first systematic literature to identify the key ingredients for assessing Industry 4.0 readiness for organizations.

Purpose The purpose of this paper is to evaluate the historical pollution of the Hostivar Reservoir (largest reservoir in Prague) sediment by metals, polyaromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) and identify the trends in pollution of aquatic environment. Design/methodology/approach Core samples, 140 cm long, recording the 45-year history of the reservoir, were separated to 5 cm width subsamples (approximately 1.5 years of sedimentation) and analyzed for metals (Cd, Pb, Cu, Zn, Cr, Ni, Al), PAH and PCB. Following methods were used: US EPA 3051 for metals, US EPA 505 and US EPA 8082 A for PCB, and ISO 18287:2006 for PAH. Findings Most of the contaminants had the highest concentration at the beginning of the existence of the reservoir, suggesting that the contamination results from construction activities. Significant decrease of Pb occurred in the second half of the 1990s. It was caused by termination of the addition of lead as a detonation suppressant to the gasoline. Most concentrations of PAHs, PCBs and metals, except copper do not present eco-toxicological risk. Practical implications The results show the volume of priority pollutants removed from the reservoir by sediment extraction, and point risk to the terrestrial environment due to application of the sediment in the construction of a noise protecting wall. Originality/value The paper presents unique data about historical contamination of the largest reservoir in Prague, the capital of Czech Republic. It shows how the watershed and the construction phase of the dam cause a pollution of the reservoir sediment and possible environmental risk for aquatic biota.

Purpose – The purpose of this paper is to provide an overview of the development of the SME sector in Australia, concentrating on a number of key areas: small business definitions and numbers; the role of government; the emergence of key industry groups; and the evolution of education, training and research services. Design/methodology/approach – The study is a result of extensive literature reviews, desk research and the recollections of various participants in the field. Findings – There have been major changes to the Australian small business sector over the last 40 years. In 1983-1984 there were an estimated 550,000 small firms, and by 2010 this had grown to almost two million. Government involvement in, and support for, SMEs was virtually non-existent before 1970. Following the delivery of the Wiltshire report (1971), however, both state and federal governments responded by developing specialist advisory services, funding programmes and other support tools. Virtually non-existent before the 1970s, several peak industry associations were formed between 1977 and the 1990s. At the same time, formal education and teaching in the area expanded in the 1970s and 1980s and is now widespread. Practical implications – Development of the small business sector in Australia has often paralleled similar trends in other OECD nations. State and territory governments have often (but not always) been the principal drivers of policy change. Originality/value – There has been no little, if any, prior documentation of the evolution of the small business sector in Australia in the last 40 years.

PurposeThe purpose of this paper is to examine the transformations of prosthetic practices in China, as well as the daily experiences and dilemmas arising from the everchanging practices since 1949. On the basis of materials, this paper explores an everyday perspective to review the history of technology.Design/methodology/approachEthnography was collected with the application of participant observations, informal interviews and in-depth interviews during a 13-months study at a rehabilitation center in Chengdu, China. The literature on prosthetic manufacturing was also reviewed for this paper.FindingsChina's prosthetic technology seems to evolve from traditional to modern. However, this progressive narrative – innovation-based timeline (Edgerton, 2006, xi) – has been challenged by daily practices. Due to institutional pressures, prosthetists are in a dilemma of selectively using their knowledge to create one kind of device for all prosthesis users with a certain kind of disability, thereby regulating the physical and social experiences of prosthesis users. Besides, prosthesis users are accustomed to prostheses made with old techniques, and must correct themselves from old experiences to the daily practices recognized by the selected techniques.Originality/valueThis paper provides a cross-cultural case to reexamine Edgerton's criticism of the progressive and orderly innovation-centric technological narrative. More importantly, it reviews the history and practices of China's prosthetics from daily experiences rather than Edgerton's concentration on technology; therefore, it provides an everyday perspective for future research on technological transformations.

Purpose After direct elections were instituted in Hong Kong and the sovereignty was transferred from Britain to China, politicization inevitably followed democratization. The purpose of this paper is to evaluate the pro-democratic political parties’ politics in Hong Kong in recent history. Design/methodology/approach The research was conducted through a historical comparative analysis, within the context of Hong Kong after the sovereignty handover and the interim period of crucial democratization. Findings With the implementation of “One country, Two systems,” political democratization was hindered in Hong Kong’s transformation. The democratic forces have no alternative but to seek more radicalized politics, which has caused a decisive and ineluctable fragmentation of the local political parties. Originality/value This paper explores and evaluates the political history of the Hong Kong Special Administrative Region under “One country, Two systems” and the ways in which the limited democratization hinders the progress of Hong Kong’s transformation.
