The purpose of this study is to propose a simplifying approach for modelling a reliability test. Modelling the reliability tests of printed circuit board (PCB)/microelectronic component assemblies requires the adoption of several simplifying assumptions. This study introduces and validates simplified assumptions for modeling a four-point bend test on a PCB/wafer-level chip scale packaging assembly.

In this study, simplifying assumptions were used. These involved substituting dynamic imposed displacement loading with an equivalent static loading, replacing the spherical shape of the interconnections with simplified shapes (cylindrical and cubic) and transitioning from a three-dimensional modelling approach to an equivalent two-dimensional model. The validity of these simplifications was confirmed through both quantitative and qualitative comparisons of the numerical results obtained. The maximum principal plastic strain in the solder balls and copper pads served as the criteria for comparison.

The simplified hypotheses were validated through quantitative and qualitative comparisons of the results from various models. Consequently, it was determined that the replacement of dynamic loading with equivalent static loading had no significant impact on the results. Similarly, substituting the spherical shape of interconnections with an equivalent shape and transitioning from a three-dimensional approach to a two-dimensional one did not substantially affect the precision of the obtained results.

This study serves as a valuable resource for researchers seeking to model accelerated reliability tests, particularly in the context of four-point bending tests. The results obtained in this study will assist other researchers in streamlining their numerical models, thereby reducing calculation costs through the utilization of the simplified hypotheses introduced and validated herein.

In July 2021, the European Commission has proposed a set of conjunct initiatives to reform the antimoney laundering/countering the financing of terrorism (AML/CFT) regulatory regime in Europe with the main aims to (i) harmonize the AML/CFT regulation and (ii) centralize the authority to a higher degree at European Union (EU) level. This paper aims to assess the reform in light of the EU subsidiarity principle.

The paper uses a benchmark approach to compare the proposed EU money laundering reform against Article 5(3) of the Treaty on the Functioning of the European Union.

The paper confirms that more centralized decision-making at EU level in this policy area is justified, mainly because (i) the policy area is not an area where the EU has exclusive competence, (ii) EU centralized action is necessary and (iii) it also adds value, for instance, for level playing field and efficiency considerations as long as local information advantage will not be lost. As such, the subsidiarity principle can be applied and is an adequate tool to legitimize EU centralized action in the field of money laundering combat.

As the EU AML regulatory reform has not yet been sufficiently discussed in light of the subsidiarity principle, the article is of innovative nature.

This paper aims to explore how HR leaders can help their managers ditch the traditional command-and-control leadership style and instead adopt an enquiry-led management approach – Operational Coaching^®. This approach helps managers to develop coaching-related behaviours in their day-to-day interactions with teams, to cultivate a culture that is more collaborative, inclusive and innovative with measurable improvements in engagement, productivity and performance.

Responding to the UK’s woeful productivity and employee engagement levels, the Government sponsored a large-scale academic research study (designed, conducted and independently evaluated by the London School of Economics, LSE) to assess the impact of managers learning to use an Operational Coaching^® style of management. Managers in 62 organisations across 14 sectors worked through a learning programme designed to build managers’ confidence in using intentional enquiry as a part of their everyday management style.

LSE proved, statistically significantly, that managers increased the amount of time they spent coaching their team members by an average of 70% and generated a 74 times return on investment. LSE also noted that intervention group organisations indicated a positive sixfold improvement in employee retention than in control group organisations.

When managers learn to use an Operational Coaching^® style of management in their day-to-day work with others, it allows them to learn how to challenge, support and grow the capabilities of their team members in ways that measurably benefit the individual and the organisation. Colleagues are more engaged, recognised and rewarded. As their competency and confidence grows, managers are released from aspects of their to-do lists and are able to invest even more attention towards coaching their team members.

The aim of this article is to examine in depth the digital nomad lifestyle and its effects in the context of tourism and to create a perspective for the future by taking into account the findings of the articles in the thematic issue.

The theme question is examined through a review of the main findings and outcomes of this issue.

The digital nomad lifestyle stands out as an alternative form of tourism to traditional tourism models. Digital nomads are interested in cultural heritage and are effective in destination marketing just as social media influencers are. Gastronomic preferences and security perceptions of digital nomads play an important role in destination selection. Although digital nomads start out with a desire for independence and freedom, they want to come together with their peers in order to meet their social needs.

This article will serve as a significant resource for understanding the digital nomad lifestyle and for predicting future tourism trends.

In this paper, the philosophy of John Rawls, known as “Justice as Fairness,” is discussed. This philosophy examines the responsibilities social actors hold toward their societal organizations. From an Islamic perspective, justice is pivotal in safeguarding collective interests, aligning with Rawls' conviction that just societies nurture happiness and foster well-being across various life aspects. To achieve customer welfare, our viewpoint underscores the importance of justice in reflecting on consumer well-being from both Rawls’ theory and Islamic perspectives.

We adopt a conceptual approach where secular views of Rawls’ “Theory of Justice” are merged with the Islamic view, resulting in novel insights regarding the hermeneutics involved in the notion of justice and the preservation of consumer well-being.

Our analysis reveals that John Rawls' “A Theory of Justice” aligns with the Islamic perspective in several respects yet diverges in others, notably in the concepts of pre-creation consciousness and divine guidance. These distinctions are emphasized in our paper.

Our paper presents a perspective on justice founded on the concepts of the “Original Position” and the “Veil of Ignorance.” The commentary explores consumer well-being by integrating Rawls' principles with an analysis that elucidates the role justice plays in enhancing societal welfare.

This strategic commentary aims to examine the benefits and drawbacks of rigid frameworks versus flexible approaches to measuring employee engagement, arguing for a hybrid model that incorporates the best of both to better correspond with organisational subtleties and strategic goals.

This study compares the standardised, benchmarking capabilities of inflexible frameworks such as Gallup’s Q12 to the adaptability and customisation potential of flexible approaches. It emphasises the creation and implementation of a hybrid methodology that preserves the integrity of engagement measurement while also incorporating organisational-specific insights.

Despite their different benefits, rigid frameworks may neglect distinct organisational cultures, whereas completely flexible techniques may suffer with measuring consistency. A hybrid model, which combines core standardised questions and unique items, provides a balanced solution for improving the relevance, actionability and reliability of engagement data across dynamic organisational landscapes.

The discussion culminates with the proposal of a hybrid measurement strategy as a strategic innovation in human resource management. By combining scientific rigour and contextual sensitivity, this model provides a nuanced roadmap for organisations looking to thoroughly understand and effectively negotiate the complexity of employee engagement in an evolving work environment.

Induction heating processes need to adapt to complex geometries or variable processes that require a high degree of flexibility in the induction heating setup. This is usually done using complex inductors or adaptable resonant tanks, which leads to costly and constrained implementations. This paper aims to propose a multi-level, versatile power supply able to adapt the output to the required induction heating process.

This paper proposes a versatile multilevel topology able to generate versatile output waveforms. The methodology followed includes simulation of the proposed architecture, design of the power electronics, control and magnetic elements and laboratory tests after building a 10-level prototype.

The proposed converter has been designed and tested using an experimental prototype. The designed generator is able to operate at 1 kVpp and 100 A at 250 kHz, proving the feasibility of the proposed approach.

The proposed converter enables versatile waveform generation, enabling advanced tests and processes on induction heating system. The proposed system allows for multifrequency generation using a single inductor and converter, or advanced tests for inductive and capacitive components used on induction heating systems. Unlike previous multifrequency proposals, the proposed generator enables a significantly improved versatility in terms of operational frequency and amplitude in a single converter.
