The purpose of this paper is to evaluate the effect of titanium oxide (TiO₂) and yttrium oxide (Y₂O₃) nanoparticles-reinforced pure aluminium (Al) on the mechanical properties of hybrid aluminium matrix nanocomposites (HAMNCs).

The HAMNCs were fabricated via a vacuum die-assisted stir casting route by a two-step feeding method. The varying weight percentages of TiO₂ and Y₂O₃ nanoparticles were added as 2.5, 5, 7.5 and 10 Wt.%.

Scanning electron microscope images showed the homogenous dispersion of nanoparticles in Al matrix. The tensile strength by 28.97%, yield strength by 50.60%, compression strength by 104.6% and micro-hardness by 50.90% were improved in HAMNC1 when compared to the base matrix. The highest values impact strength of 36.3 J was observed for HAMNC1. The elongation % was decreased by increasing the weight percentage of the nanoparticles. HAMNC1 improved the wear resistance by 23.68%, while increasing the coefficient of friction by 14.18%. Field emission scanning electron microscope analysis of the fractured surfaces of tensile samples revealed microcracks and the debonding of nanoparticles.

The combined effect of TiO₂ and Y₂O₃ nanoparticles with pure Al on mechanical properties has been studied. The composites were fabricated with two-step feeding vacuum-assisted stir casting.

Powder bed fusion-laser beam (PBF-LB) is a rapidly growing manufacturing technology for producing Al-Si alloys. This technology can be used to produce high-pressure die-casting (HPDC) prototypes. The purpose of this paper is to understand the similarities and differences in the microstructures and properties of PBF-LB and HPDC alloys.

PBF-LB AlSi10Mg and HPDC AlSi10Mn plates with different thicknesses were manufactured. Iso-thermal heat treatment was conducted on PBF-LB bending plates. A detailed meso-micro-nanostructure analysis was performed. Tensile, bending and microhardness tests were conducted on both alloys.

The PBF-LB skin was highly textured and softer than its core, opposite to what is observed in the HPDC alloy. Increasing sample thickness increased the bulk strength for the PBF-LB alloy, contrasting with the decrease for the HPDC alloy. In addition, the tolerance to fracture initiation during bending deformation is greater for the HPDC material, probably due to its stronger skin region.

This knowledge is crucial to understand how geometry of parts may affect the properties of PBF-LB components. In particular, understanding the role of geometry is important when using PBF-LB as a HPDC prototype.

This is the first comprehensive meso-micro-nanostructure comparison of both PBF-LB and HPDC alloys from the millimetre to nanometre scale reported to date that also considers variations in the skin versus core microstructure and mechanical properties.

Social impact research remains in its infancy. The purpose of the paper is to build on Keeling and Marshall’s (2022) “Call for impact” paper and develop a comprehensive social impact pathway (SIP) framework. The aim is to encourage marketing researchers, non-profits and corporations to pursue impactful work that is valued, planned, monitored and evaluated.

The conceptual paper explores the complexities of estimating social impact drawing from a range of illustrative cases.

The paper identifies a lack of clarity in the understanding and application of impact and presents a pathway aimed at increasing focus on social impact across future work to deliver the net-positive changes that are needed to reverse biodiversity decline, climate change and social and health inequalities that continue to be persist and be experienced by so many planet wide.

This paper contributes a pathway forward to encourage and support increased utilisation of the framework in future marketing research.

Mapping and measuring SIPs are concerted efforts directing understanding towards identifying the activities that are contributing to the delivery of outputs that can achieve intended outcomes. The measurement of impact directs investment towards activities that ensure net-positive gains are achieved.

Ever growing social inequities, health disparities, loss of biodiversity and environmental degradation occur when practices are left unchecked. A focus on impact avoids greenwashing practices, ensuring that an understanding of what has changed because of the work is transparently reported.

This paper aims to encourage marketing researchers to engage in social change projects, rather than solely disseminating academic findings. Emphasising the importance of an outside-in approach, this paper highlights the necessity of showcasing accumulated outcomes to demonstrate impact.

This paper aims to investigate the influence of “BroncoCut-X” (copper core-ZnCu50 coating) electrode on the machining of Ti-3Al-2.5V in view of its extensive use in aerospace and medical applications. The machining parameters are selected as Spark-off Time (ST_off), Spark-on Time (ST_on), Wire-speed (S_w), Wire-Tension (WT) and Servo-Voltage (S_v) to explore the machining outcomes. The response characteristics are measured in terms of material removal rate (MRR), average kerf width (KW) and average-surface roughness (SA).

Taguchi’s approach is used to design the experiment. The “AC Progress V2 high precision CNC-WEDM” is used to conduct the experiments with ϕ 0.25 mm diameter wire electrode. The machining performance characteristics are examined using main effect plots and analysis of variance. The grey-relation analysis and fuzzy interference system techniques have been developed to combine (called grey-fuzzy reasoning grade) the experimental response while Rao-Algorithm is used to calculate the optimal performance.

The hybrid optimization result is obtained as ST_off = 50µs, ST_on = 105µs, S_w = 7 m/min, WT = 12N and S_v=20V. Additionally, the result is compared with the firefly algorithm and improved gray-wolf optimizer to check the efficacy of the intended approach. The confirmatory test has been further conducted to verify optimization results and recorded 8.14% overall machinability enhancement. Moreover, the scanning electron microscopy analysis further demonstrated effectiveness in the WEDMed surface with a maximum 4.32 µm recast layer.

The adopted methodology helped to attain the highest machinability level. To the best of the authors’ knowledge, this work is the first investigation within the considered parametric range and adopted optimization technique for Ti-3Al-2.5V using the wire-electro discharge machining.

This study applies Garfinkel’s (1967) concept of ‘breaching experiment’ to explore the impact of COVID-19-induced disruptions on the ‘emotion management’ practices of residential care workers in the United Kingdom and Germany. It examines the influence of professional feeling rules on workers, emphasizing the prescribed importance of displaying affective, empathetic concern for residents’ health and well-being. Findings demonstrate that authenticity and adherence to professional feeling rules in relation to emotional management are not mutually exclusive. The authors underscore how adherence to professional feeling rules upholds authentic care by reinforcing a professional ethos, which acts as a cornerstone motivating residential care workers. Ultimately, the study showcases how a professional ethos substantiates altruistic motivations, guiding proficient emotion management practices among care workers. It highlights how these workers drew upon their personal understanding and experiences to determine the appropriate emotions to express while providing care for residents amid the unprecedented challenges of the pandemic.

Developing nations are starting to take centre stage and are becoming more conscious of their economic potential in the tourism sector. Earlier, these countries were largely left out of the tourist sector. Today, the foreign exchange reserves of these nations are mostly derived from tourism and a nation's balance of payments derived through tourism supports international trade and stabilizes the economy. The chapter adopts a case study method to evaluate the prospects of inclusive growth through socio economic well-being. In the dynamic and constantly evolving tourism industry, it is imperative to make the growth more inclusive so that there is a balanced approach to long term sustainable development. When it comes to using traditional skills and cultural heritage to participate in this economic paradigm, rural artisans face both opportunities and challenges as the global tourism landscape undergoes evolving transformations. The study commences by closely examining the current market obstacles that rural artisans in the tourism industry face, which encompass a range of issues such as shifting consumer preferences, market saturation and the aftermath of external shocks like pandemics. The chapter indicates major obstacles impeding the integration of rural artisans into the tourism value chain by means of a thorough empirical analysis. In order to overcome the obstacles, the study investigates inclusive growth and how it might act as a spur to improve the socio-economic circumstances of rural craftsmen. The findings in the chapter distil best practices that promote inclusivity, empower local communities and support sustainable tourism development by looking at successful case studies and policy interventions.

Social commerce (s-commerce) has gained widespread popularity as a social platform where customers engage in resource-sharing activities such as information exchange, advice-seeking and expressing their opinions on mutual interests. However, existing studies have not fully comprehended the drivers of electronic customer-to-customer interaction (eCCI) and how such behavior contributes to the customer “stick” on s-commerce sites. This study develops the Motivation–Opportunity–Ability (MOA) theory and investigates the impact of MOA factors on eCCI, which in turn affects customer stickiness.

A survey was used to acquire data from 455 valid respondents, and the research employed a combination of fuzzy-set qualitative comparative analysis (fsQCA) and structural equation modeling.

The results revealed associations between perceived self-efficacy, intrinsic motivation, tie strength with other customers, eCCI and customer stickiness.

Considering the limited availability of complete eCCI frameworks in existing scholarly works, the authors present valuable perspectives on the role of consumer characteristics as both antecedents and consequences of eCCI. Additionally, this study proposes a research agenda for the field of eCCI on s-commerce sites.
