Purpose This study aims to deal with development and performance analysis of high-velocity oxy-fuel (HVOF) thermally sprayed Mo2C-based WC-CoCr (tungsten carbine cobalt chrome) (Co-10% and Cr-4%) cermet coating deposited on the pump impeller steel 316 L. Design/methodology/approach In this work, a study was carried out by modifying the conventional WC-CoCr powder with a small addition of molybdenum carbide (Mo2C). Reinforcement was done by 1–4 wt.% addition of Mo2C feedstocks in WC-CoCr powder by using a jar ball mill process. The design of experiment was implemented for optimization of the percentage of Mo2C feedstock. L16 (4 × 4) orthogonal array was used to design the experiments for erosion output for the input parameters namely velocity, particle size, concentration and Mo2C proportion. Findings Results show that the Mo2C-based WC-CoCr coating provides better microhardness as compared to conventional WC-CoCr coating. The present study also reveals that the deposition of conventional WC-CoCr coating has improved the wear resistance of SS 316 L by 9.98%. However, the slurry erosion performance of conventional WC-CoCr coating was improved as 69.6% by the addition of 3% Mo2C. Practical implications WC-CoCr coatings are universally used for protecting the equipment and machinery from abrasion, erosion and corrosion. So, the 3% Mo2C-based WC-CoCr can be useful in power plants and various industries like mining, chemical, automobile, cementing and food processing industries. Originality/value A new HVOF coating has been developed by the addition of Mo2C feedstock in WC-CoCr powder (Co 10% and Cr 4%) and the percentage of Mo2C feedstock was optimized to improve the tribological behavior of WC-CoCr coating.

Purpose This study aims to identify variability in aviation operators in order to gain greater understanding of the changes in aviation professional groups. Research has commonly addressed human factors and automation in broad categories according to a group’s function (e.g., pilots, air traffic controllers [ATCOs], engineers). Accordingly, pilots and Air Traffic Controls (ATCOs) have been treated as homogeneous groups with a set of characteristics. Currently, critical themes of human performance in light of systems’ developments place the emphasis on quality training for improved situational awareness (SA), decision-making and cognitive load. Design/methodology/approach As key solutions centre on the increased understanding and preparedness of operators through quality training, the authors deploy an iterative mixed methodology to reveal generational changes of pilots and ATCOs. In total, 46 participants were included in the qualitative instrument and 70 in the quantitative one. Preceding their triangulation, the qualitative data were analysed using NVivo and the quantitative analysis was aided through descriptive statistics. Findings The results show that there is a generational gap between old and new generations of operators. Although positive views on advanced systems are being expressed, concerns about cognitive capabilities in the new systems, training and skills gaps, workload and role implications are presented. Practical implications The practical implications of this study extend to different profiles of operators that collaborate either directly or indirectly and that are critical to aviation safety. Specific implications are targeted on automation complacency, bias and managing information load, and training aspects where quality training can be aided by better understanding the occupational transitions under advanced systems. Originality/value In this paper, the authors aimed to understand the changing nature of the operators’ profession within the advanced technological context, and the perceptions and performance-shaping factors of pilots and ATCOs to define the generational changes.

Purpose – One problem that many organisations face today in the global economy is that too few ideas are turned into innovations. The purpose of this paper is to show how innovations in organisations may be obtained by means of creative energy fields. Design/methodology/approach – The design employed in the research represents a holistic, change oriented approach to innovation, and the methodology is conceptual where an analytical model is used. Findings – The paper provides arguments that organisations need to develop creative energy fields in order to enhance their innovative capacity and performance. In the paper the construct creative energy field is conceptualised as “a spot in an organisation where a Group of creative individuals collaborate and work together in order to bring to surface new ideas which may fuel innovation processes and Development in organisations”. The paper shows that creative energy fields are influenced by five distinct components; those of making a clear purpose, planning after the results have become apparant, an organisation’s rule breakers, drawing a map that changes the landscape, and igniting the flame of innovation. Furthermore, the findings encompass three conditions which need to be present in an organisation in order to make creative energy fields work. Research limitations/implications – The carried out focuses on the individual organisation which aims to enhance innovation performance. Practical implications – In relation to practical implications, the paper shows, in particular, how an organisation may move into areas of innovation by means of a Lego system of organising. Originality/value – To the authors’ knowledge, the creation and use of a novel construct, that of creative energy fields, represents newness and originality in innovation research at the level of the individual enterprise. Furthermore, the paper contributes to the extant management knowledge of innovation by showing how a Lego system of organising may foster innovation at the enterprise level.

PurposeAs service organizations move toward the open system strategic customer orientation, they need to ensure consistency among competitive methods, performance measures and strategies utilized. This paper aims to examine the relationships among these important facets of today’s service organizations. The study at hand examines the relationship among competitive methods, implicit strategy and performance measures used by Portuguese service organizations.Design/methodology/approachThis research uses a survey-based methodology. Factor analysis, cluster analysis and regression analysis procedures are used to analyze the collected data from Portuguese service organizations.FindingsBased on the results of this study, it appears that some of the studied service organizations are steadily moving toward the open system mode of strategy, competitive methods and performance measurement. However, the majority of the service organizations examined appeared to be in a state of strategic confusion, as they appear to lack the consistency among competitive methods, performance measures and desired strategic orientations.Research limitations/implicationsThe sample used in this study is specific in nature, as it includes only Portuguese service organizations. Therefore, the results of this study should be interpreted with caution. Future research in other cultural service settings is recommended. Such research should emphasize the exploration of theoretical frameworks, which tend to practically integrate competitive methods, performance measures and strategic orientation.Practical implicationsThis study has direct practical implications for service managers, as they attempt to integrate their organizational systems. As such, the research in this study paves the way toward the practical integration and consistency among competitive methods, performance measures and strategic orientations needed to enhance the customer orientation. In this context, such integration and consistency are essential to enhance the strategic competitiveness of today’s service organizations operating in a dynamic marketplace.Originality/valueThis research combines bodies of knowledge dealing with competitive methods, performance measures and their impact on strategic orientations. The conceptual framework offered in this research attempts to facilitate the understanding for consistent practice pertaining to the competitiveness of the open system service organization in a dynamic environment. Such consistency is essential to the competitiveness of the organization in a dynamic environment.

Purpose Money Laundering Reporting Officers (MLROs) carry out day-to-day anti-money laundering (AML) tasks while directors ultimately remain responsible for AML compliance. Therefore, directors’ expectations of what their MLROs do should ideally coincide with what their actual tasks to minimise liability risk. This paper aims to test for gaps between MLROs and their directors in terms of knowledge, expectations and performance of AML tasks. Likewise, it is researched whether MLROs and directors communicate well with regard to MLROs’ tasks. Design/methodology/approach This paper first develops a model for analysing the dyadic relationship between MLROs and their directors, based on the audit expectation-performance gap. Second, a paired electronic survey of MLROs and directors of German companies was conducted in autumn 2020, testing for participants’ knowledge, expectations and performance of possible AML tasks (n = 136 pairs). Findings While there is no knowledge or performance gap among MLROs and directors, expectations among them are partially unreasonable and their communication needs to be improved. Additionally, this study suggests that MLROs of German non-financial businesses are less knowledgeable, perform AML duties more poorly, and communicate less effectively with their directors. Practical implications Training of MLROs and communication with their directors need to be improved. Especially in the non-financial sector, action is urgently required. Originality/value This paper reports the results of the first paired survey of MLROs and their directors, offering unique insights into their relationship and the status of private AML efforts.

PurposeIn this article, we identify various foodservice-related attributes that are important for undergraduate students residing in hostels and avail service from specific foodservice providers. We also investigate the performance of attributes to determine areas where the foodservice providers should maintain a high performance or where improvement is required.Design/methodology/approachWe apply the Kano methodology to design the questionnaire for 24 different attributes. For each attribute, we construct three questions; namely, functional type, dysfunctional type, and performance of the hostel foodservice. We collect a total of 317 responses. We use multiple methods to determine the dominant category. Finally, combining the values of these methods, we study relative positions of the attributes in the importance–performance grid.FindingsBased on the Kano categorization, quality-related attributes are most important, followed by hygiene, comfort, availability, variety, and time, in the descending order. The gender of the respondent plays an important role in categorization of some attributes. Using the importance–performance analysis, we identify the attributes where the foodservice provider should maintain a high performance or where improvement is required. Improvements in some attributes are difficult due to foodservice provider's self-assessment of high performance or high difficulty for improvement.Originality/valueIn this study, we examine the importance of various foodservice attributes among undergraduate residential students. We combine multiple methods of Kano categorization to compute importance values of the attributes. We also investigate the reasons behind the gap between student's and foodservice manager's perception of the performance of these attributes.
