Abstract

Purpose

The purpose of this paper is to show that the droplet impact phenomenon is important for the advancement of industrial technologies in many fields such as spray cooling and ink jet printing. Droplet bouncing on the nonwetting surfaces is a special phenomenon in the impact process which has attracted lots of attention.

Design/methodology/approach

In this work, the authors fabricated two kinds of representative nonwetting surfaces including superhydrophobic surfaces (SHS) and a slippery liquid-infused porous surface (SLIPS) with advanced UV laser processing.

Findings

The droplet bouncing behavior on the two kinds of nonwetting surfaces were compared in the experiments. The results indicate that the increasing Weber number enlarges the maximum droplet spreading diameter and raises the droplet bounce height but has no effect on contact time.

Originality/value

In addition, the authors find that the topological SHS and SLIPS with the laser-processed microwedge groove array produce asymmetric droplet bouncing with opposite offset direction. Microdroplets can be continuously transported without any additional driving force on such a topological SLIPS. The promising method for manipulating droplets has potential applications for the droplet-based microfluidic platforms.

Abstract

Purpose

On 12th June 2015, a strike by contract workers was declared at Rampur terminal, All India Business in oil corporation (ABC) Ltd. The strike had disrupted the normal services of the terminal. Under such circumstances, Mr Ravi Sharma (Head human resources of the eastern region, ABC Ltd.) was unable to decide how to save the company from such a disorderly situation without any increased loss of production and manpower cost liabilities. Could Mr Ravi Sharma resolve the issue of strike through an approach of strategic rapprochement when the disruptions made by workers and local miscreants went out of control?

Design/methodology/approach

In-depth interview in the year 2019 was conducted with the protagonist Mr Ravi Sharma and the trade union members at the regional office of ABC Ltd., Kolkata and Rampur Terminal, respectively, to convert the narratives in the form of a fictitious case study. Four rounds of interviews were conducted by the author to complete the data collection procedure. The company™s-related information was sourced through a secondary database furnished by company™s officials. However, the data about the company, the key characters and other recognizable information have been disguised to preserve the confidentiality of information.

Findings

The strike was called by the contract workers at Rampur terminal for two primary reasons, namely, wage increase and giving preference to local people for employment whether regular or contract. Mr Ravi Sharma could pacify the unforeseen situation by adopting two-pronged strategies, namely, first, he could successfully gain the confidence of the union leader and secondly, set the environment for the conciliation proceeding so that agreement settled will not be failed to be implemented.

Originality/value

The case uses a system perspective of Industrial relation proposed by Dunlop (1958) to highlight the interplay between employer, government and trade unions influenced by politics and mafia that determine eventually the industrial peace in the organization.

Abstract

Purpose

Poor maintenance management leads to non-negligible economic, environmental and social impacts and obstacles to the sustainable manufacturing paradigm. Studies evaluating maintenance impacts on sustainability underline growing interest in the topic, but reports on the industrial field are lacking. Therefore, this paper investigates the industrial environment and the indicators that manufacturing companies use for measuring their maintenance impacts.

Design/methodology/approach

In this pilot survey study, several stakeholders of production enterprises in the south of Italy were interviewed to unveil the spread of the measurement of maintenance impacts on sustainability and the indicators used by those companies.

Findings

The interview results showed a low level of awareness among stakeholders about maintenance impacts on sustainability. Maintenance stakeholders are mainly focused on technical and economic factors, whereas environmental, quality and safety stakeholders are becoming more aware of maintenance impacts on environmental and social factors. However, both groups need guidelines to define sustainability indicators to assess such impacts.

Originality/value

This exploratory study allowed us to investigate the current situation in industrial organisations and achieve the first variegated and diversified vision of the awareness of company stakeholders on maintenance impacts on the sustainability of several business functions. This paper provides a valuable contribution to “maintenance and sustainability” research area in production contexts and sheds light on non-negligible maintenance impacts on sustainability, providing preliminary insights on the topic and an effective basis for defining future research opportunities. Moreover, this study enables increased awareness among internal and external manufacturing company stakeholders on the role of maintenance in sustainable production.

Abstract

Purpose

Output from the Irish Dairy Industry has grown rapidly since the abolition of quotas in 2015, with processors investing heavily in capacity expansion to deal with the extra milk volumes. Further capacity gains may be achieved by extending the processing season into the winter, a key enabler for which being the reduction of duration of the winter maintenance overhaul period. This paper aims to investigate if Lean Six Sigma tools and techniques can be used to enhance operational maintenance performance, thereby releasing additional processing capacity.

Design/methodology/approach

Combining the Six-Sigma Define, Measure, Analyse, Improve, Control (DMAIC) methodology and the structured approach of Turnaround Maintenance (TAM) widely used in process industries creates a novel hybrid model that promises substantial improvement in maintenance overhaul execution. This paper presents a case study applying the DMAIC/TAM model to Ireland’s largest dairy processing site to optimise the annual maintenance shutdown. The objective was to deliver a 30% reduction in the duration of the overhaul, enabling an extension of the processing season.

Findings

Application of the DMAIC/TAM hybrid resulted in process enhancements, employee engagement and a clear roadmap for the operations team. Project goals were delivered, and original objectives exceeded, resulting in €8.9m additional value to the business and a reduction of 36% in the duration of the overhaul.

Practical implications

The results demonstrate that the model provides a structure that promotes systematic working and a continuous improvement focus that can have substantial benefits for wider industry. Opportunities for further model refinement were identified and will enhance performance in subsequent overhauls.

Originality/value

To the best of the authors’ knowledge, this is the first time that the structure and tools of DMAIC and TAM have been combined into a hybrid methodology and applied in an Irish industrial setting.

Abstract

Purpose

The purpose of this paper is to investigate the effect of remelting each layer on the homogeneity of nickel-titanium (NiTi) parts fabricated from elemental nickel and titanium powders using laser powder bed fusion (LPBF). In addition, the influence of manufacturing parameters and different melting strategies, including multiple cycles of remelting, on printability and macro defects, such as pore and crack formation, have been investigated.

Design/methodology/approach

An LPBF process was used to manufacture NiTi alloy from elementally blended powders and was evaluated with the use of a remelting scanning strategy to improve the homogeneity of fabricated specimens. Furthermore, both single melt and up to two remeltings were used.

Findings

The results indicate that remelting can be beneficial for density improvement as well as chemical and phase composition homogenization. Backscattered electron mode in scanning electron microscope showed a reduction in the presence of unmixed Ni and Ti elemental powders in response to increasing the number of remelts. The microhardness values of NiTi parts for the different numbers of melts studied were similar and ranged from 487 to 495 HV. Nevertheless, it was observed that measurement error decreases as the number of remelts increases, suggesting an increase in chemical and phase composition homogeneity. However, X-ray diffraction analysis revealed the presence of multiple phases regardless of the number of melt runs.

Originality/value

For the first time, to the best of the authors’ knowledge, elementally blended NiTi powders were fabricated via LPBF using remelting scanning strategies.

Abstract

Purpose

Currently, China’s economy is in the critical phase of transforming economic development patterns and replacing old growth drivers with new ones. Whether it can successfully overcome the “middle-income trap” has become a significant issue attracting wide attention.

Design/methodology/approach

Driven by underlying digital technologies such as artificial intelligence, blockchain, cloud computing and big data, the fourth industrial revolution featuring the booming digital economy has provided significant opportunities for China’s economy to “overtake” and overcome the “middle-income trap”. The transformation of economic development pattern, the optimization of industrial structure, and the change of growth drivers, brought by the deep integration of digital and real economies are the keys to leaping over the “middle-income trap”.

Findings

From the supply side, the digital economy can improve the quality and efficiency of the supply side and promote the supply-side structural reform and economic growth from the following three aspects: First, promote the quality, efficiency and diversification of the supply system; second, promote networking, opening-up and synergy in the innovation system and third, promote the socialization, modularization and flexibility of production pattern. From the demand side, the digital economy can boost the new drivers of the “troika” of economic growth consisting of consumption, exports and investment by changing the market investment direction, promoting consumption upgrade and fostering export strengths. However, once these two attributes interact with each other, especially when data is combined with capital, the most adhesive factor in the market economy, a series of new social relations will then be produced based on the technical attribute, resulting in significant adjustments in social relations, involving both positive and negative externalities.

Originality/value

To overcome the “middle-income trap”, it is necessary to adapt to the laws of economic evolution and promote a fundamental change in economic growth drivers; boost the high-quality development of the digital economy by strengthening the support role of data in the digital economy; and accelerate digital industrialization and industrial digitalization to realize the integration of digital and real economies.

Abstract

Purpose

The purpose of this paper is to explore how sustainability reporting is shaped by the global influences and particular national context where businesses operate.

Design/methodology/approach

The paper uses both content analysis of published sustainability information and semi-structured interviews with corporate managers to explore how sustainability reporting is used to address unique social and environmental challenges in a developing country – Sri Lanka. The use of integrative social contracts theory in investigating sustainability reporting offers novel insights into understanding the drivers for sustainability reporting practices in this particular country.

Findings

The findings reveal that managers’ perceptions about usefulness of sustainability reporting, local contextual challenges and global norms influence the extent to which companies engage in sustainability reporting and the nature of sustainability information reported. In particular, Sri Lankan company managers strive to undertake sustainability projects that are beneficial not only to their companies but also to the development of the country. However, while company managers in Sri Lanka are keen to undertake sustainability reporting, they face different tensions/expectations between global expectations and local contextual factors when undertaking sustainability projects and reporting. This is also showcased in what is ultimately reported in company annual reports, where some aspects of sustainability, e.g. social, tend to focus more on addressing local concerns whereas other disclosures are on issues that may be relevant across many contexts.

Research limitations/implications

Important insights for government and other regulatory authorities can be drawn from the findings of this study. By capitalising on the strong sense of moral duty felt by company managers, policymakers can involve the business sector more to mitigate the social and environmental issues prevalent in Sri Lanka. The findings can also be used by other developing countries to enable pathways to engage with the corporate sector to contribute to national development agendas through their sustainability initiatives and projects.

Originality/value

While the usual understanding of developing country’s company managers is that they try to follow global trends, in Sri Lanka, this research shows how managers are trying to align their responsibilities at a national level with global principles regarding sustainability reporting. Therefore, this paper highlights how both hypernorms and microsocial rules can interact to define how company managers undertake sustainability reporting in a developing country.

Abstract

Purpose

This study explores the relationship between corruption and shadow economy (SE) by examining the potential links and interactions between these two phenomena to see whether it is a one-way or two-way relationship and a complementarity or substitution linkage.

Design/methodology/approach

Using a dataset comprised of 145 countries all over the world between 1996 and 2015, the authors apply the simultaneous two-step system generalized method of moments approach to address the research question.

Findings

The study findings support a positive bidirectional relationship between corruption and SE. As such, this study has provided evidence supporting the complementarity association. In the authors' further analyses, they point out that several factors can moderate this positive bidirectional linkage. In particular, while Foreign Direct Investment (FDI) inflows strengthen it, it is weakened by other institutional factors such as civil liberties and political rights. Finally, by splitting the full sample into three different subsamples and then examining countries at varying stages of economic development, the authors can gain valuable insights into the evolving dynamics of the relationship between corruption and SE. Specifically, while the authors observe that the positive direction of corruption to SE remains unchanged across different nations, they observe that the positive influence of SE on corruption is strongest among developed economies only.

Practical implications

The study findings provide an important policy implication. This study highlights the synergistic relationship between SE and corruption, indicating that reducing corruption will reduce the size of the SE. Consequently, this reduction in the SE can mitigate the adverse effects of corruption on economic development.

Originality/value

This paper is among the first empirical studies that critically investigate the interrelationship between SE and corruption. It then explores how this two-way linkage is conditional on some factors, such as economic development levels and institutional quality indicators.

Abstract

Purpose

The purpose of this paper is to review the roles of human resource management (HRM) specialists in the contemplation and implementation of innovation in employing organisations and workplaces.

Design/methodology/approach

The authors review some of the literature and practice in this field as well as 11 other articles that are included in this special issue.

Findings

The authors propose six research questions. First, are HRM specialists analysing relevant trends and their implications for the future of work and the workforce? Second, are HRM specialists enabling employing organisations to identify and enable innovative ideas? Third, to what extent are HRM specialists leading partnership arrangements with organised labour? Fourth, what is the role of HRM specialists in creating inclusive work environments? Fifth, how should HRM specialists change to foster enterprise performance, intrapreneurship, agility, creativity and innovation? Sixth, to what extent is there an HRM function for line managers in coordination with HRM specialists in engendering innovation around “change agent” roles?

Originality/value

The authors argue that HRM specialists should embrace and enable innovation. The authors challenge HRM specialists to consider how they can contribute to facilitating innovation. The paper proposes further research on HRM and range of associated stakeholders who, together, have responsibility for innovating in the design and delivery of HRM to enrich our knowledge of HRM and workplace innovations.
