Purpose This paper aims to study drop formation in piezoelectric industrial printheads during the inkjet printing processes. It presents how the piezoelectric printhead forms drops of nanoparticle ink and how the problems with different values of drop parameters may influence the printed pattern’ defects and quality. Design/methodology/approach A piezoelectric printhead with 128 nozzles was activated to operate in a controlled manner, and the droplets ejected from the nozzles were observed during falling and analysed in the printview system. The effect of varying the values of drop parameters on print quality and pattern defects has been analysed and discussed. Findings The obtained results allow the identification of the sources of the technological problems in obtaining repeatable performance drops with the desired properties, and indicate the importance of choosing the appropriate individually chosen strategy of controlling the printing for each individual application to get good-quality and free-from-defects patterns. Research limitations/implications Because of the chosen research method (arbitrary selected printhead type and ink manufacturer), this study could have limited universality. Authors encourage the study of other kinds of piezoelectric heads or other conductive inks. Practical implications This study includes practically useful applications for users to improve the inkjet print quality. Originality/value This study presents results of original empirical research works on problems of the drops forming in the inkjet printing process, and finally, it identifies problems that must be resolved to disseminate this technology.

Purpose The purpose of this paper is to demonstrate how collaborative contracts can improve industrial maintenance contract relationships. Design/methodology/approach The research compares performance contracts with collaborative contracts, a new contract type whereby the contract parties align their objectives. The study uses game theory and describes the contract types as mechanism designs to compare the contract types. The mechanisms are validated with case studies. The utility of the contract types is verified with Monte Carlo simulations using expert opinions. Findings The research demonstrates that, under certain conditions, collaborative contracts result in a higher utility than performance contracts for all contract parties. Practical implications The use of collaborative contracts between an operator of a technical system and a maintenance organisation reduces maintenance costs and improves the availability of the technical system, increasing the utility for all contract parties. Originality/value The collaborative contract is a new contract type for maintenance services and the research method provides a new approach to optimise industrial maintenance contract relationships.

Purpose This study aims to investigate business-to-business (B2B) engagement within an internet of things (IoT) ecosystem. A conceptual framework is proposed that can be used for building engagement strategies considering key actors within an IoT ecosystem. Design/methodology/approach The study used an integrative literature review as a research method and investigated engagement across several disciplines along with antecedents and outcomes of engagement to form an understanding of IoT engagement. Findings The findings in this study revealed IoT engagement antecedents as IoT readiness, commitment, communication, involvement and support and, consequently, the outcomes of IoT engagement as trust, loyalty, better performance and satisfaction. Furthermore, IoT engagement needs to be considered from three perspectives, namely, from a multidimensional perspective, beyond a dyad perspective and from the service-dominant logic perspective, which suggests thinking of goods as services and highlights the importance of value co-creation. Research limitations/implications As the study of B2B engagement within the IoT ecosystem is conceptual, empirical investigations are suggested for elaborating on the findings. Practical implications The conceptual framework provides managers within an IoT ecosystem with thorough recommendations on why to change their perspectives toward engagement; it points out drivers of engagement that need to be maintained and adds IoT readiness as a new antecedent to engagement literature. Originality/value This study contributes a coherent conceptualization of actors’ engagement within IoT ecosystems and enhances both the theoretical and practical domain of B2B engagement.

Purpose The purpose of this paper is to investigate the effects of audit client importance on future bank risk and systemic risk in US-listed commercial banks. Design/methodology/approach The authors use archival research method. Findings The authors mainly find that client importance is negatively related with future bank-specific crash risk and distress risk, and also with sector-wide systemic crash risk and systemic distress risk in the future. The authors also report some evidence that these relations become more pronounced during the crisis period than during the non-crisis period. Moreover, the effect of client importance on systemic risk is found to strengthen in banks audited by Big-N auditors, by auditors without clients who restate earnings, and by auditors with more industry expertise. Research limitations/implications These findings contribute to the auditing and systemic risk literature. Practical implications This study has implications for regulating the banking industry. Originality/value This study provides original evidence on how client importance affects bank-specific risk and systemic risk of the banking industry.

Purpose The purpose of this paper is to study the repeatability of path manufacturing in the drop on demand inkjet printing process and the influences of environmental and application factors on path resistance. Design/methodology/approach Paths were printed as multiline paths in packets one-, two- and three-layer paths on polyimide substrates using nanoparticle silver ink. The sintering conditions were determined experimentally. The paths were subjected to climatic and shock exposures and to bending processes. The resistance, profile and width of the paths were measured and analyzed. The temperature distribution for electrically heated paths was measured to identify the defects. Findings This research shows the repeatability of printing processes and identifies the sources that cause diversification in path parameters after the whole technological process. The influence of shock, climatic and mechanical exposures on path electrical properties is indicated. An effective method for identifying defects thermally is shown. Research limitations/implications The research could have limited universality by arbitrarily use of substrate material, ink, printhead, process parameters and kind of sample exposures. Practical implications The research includes practically useful information about the width, thickness, defects and resistances and their changes during a typical application for a path printed with different technological parameters. Originality/value This research presents the results of original empirical research on problems concerning the manufacture of paths with uniform parameters and shows how path parameters will change under exposures that may occur in a typical application. The research combines both production and application aspects.

Purpose – This paper aims to report on research that investigates the use of green clauses in leases of office and retail premises in England and Wales. Design/methodology/approach – The authors examined 26 recent leases of green build properties registered at HM Land Registry. The green clauses discovered were classified and compared with the model form green clauses promoted by the London-based Better Building Partnership's Green Lease Toolkit. Findings – Of the 26 leases analysed, 18 contained some form of green provision. Research limitations/implications – As the sample selected was not representative, a larger study is needed to detect trends in green leasing. This research method does not show the impact of green clauses on property management. Practical implications – This research illustrates the types of clauses that have been used in leases but also shows that green leasing principles are not yet the industry standard. Many new, long leases still make no reference to environmental practices. Originality/value – This is the first research to be done examining the green content of agreed leases and develops a methodology that can be used for future research.

PurposeThis research aims to uncover consumers' deeply hidden thoughts and feelings about store scent and its effects on shopping experiences.Design/methodology/approachFollowing a qualitative approach, this research uses Zaltman metaphor elicitation technique (ZMET). All the steps of the ZMET have been performed, and important constructs and contents have been explored.FindingsUltimately, a hierarchical value map was presented. Accordingly, the naturalness and intensity of the scent played a prominent part in its effectiveness. The pleasantness and complexity of the scent, the malodor, congruity and incongruity of the scent, as well as nostalgia, were seen as the predominant originator constructs that resulted in approach or avoidance reactions.Research limitations/implicationsThese findings have practical implications for managers seeking to design a store atmospherics making way for consumers to engage with the store and the brand. The cultural milieu in which the study was performed could be seen as a possible limitation of the study. This cultural angle should also be taken into consideration while the findings were considered.Originality/valueUsing ZMET as an innovative research method makes the study significant. By doing so, the metaphors of consumption are extended to the sensory marketing field to provide a more comprehensive understanding on the effects of store scent. Moreover, the study contributes to the existing literature of smell marketing.

Purpose The growth of collaborative consumption is beginning to stimulate management research on this phenomenon. However, so far, few scholars have studied the logistics aspects related to these developments. The purpose of this paper is to develop a conceptual approach to the logistics at work in collaborative consumption. Design/methodology/approach The authors adopt an inductive, exploratory research method, based on a content analysis involving 32 collaborative consumption initiatives screened through their websites and other secondary sources. Findings Based on the way logistics is organized in these initiatives, the authors identify and describe four types of logistics: peer to peer, business, crowd, and open logistics. Practical implications The paper makes recommendations for improving the management of collaborative consumption logistics. Originality/value Our results enrich the literature about crowd practices and collaborative consumption by conceptualizing alternative roles played by logistics and revealing its specific organizational forms.

Purpose The purpose of the paper is to study how the local stakeholders of three different tourism destinations consider who is responsible for the development of a tourism destination (if identifiable) and why. Design/methodology/approach This study takes a multiple case study approach. Three different destinations are compared. A qualitative research method was chosen. The data are based on the interviews of tourism and wellbeing professionals (tourism entrepreneurs, experts and regional developers). Findings The interview results suggest that destination leadership seems to be context-dependent. Competition, co-operation and coopetition all occur in different forms in different regions. Various kinds of co-operation are distinguishable between stakeholders of case regions, and the level of leadership among actors varies in the regions; one region is strongly managed by marketing company, while on other the co-operative store chain is apparently dominant. The roles of local educational institutes also varied depending on the case area. In addition, some entry barriers were identified. Research limitations/implications The data were collected three to four years ago, so some changes in the areas and in the roles and relationships of diverse stakeholders may have occurred. Practical implications By identifying challenges faced in diverse regions diverse destination managers can identify challenges likely to occur at destinations with similar management structures. Originality/value The paper discusses the challenges and roles of diverse stakeholders in destination management by using empirical cases.
