Impulse purchases are a phenomenon of interest in recent years that provides a high revenue stream for companies compared to planned purchases. Airports are a unique shopping environment. Travellers usually need to arrive at the airport early and can only utilise limited time to shop at duty-free stores, which makes the shopping experience time-constrained and has the potential to make impulse purchases. The main purpose of this research is to create a model to examine whether “time pressure” and “hedonic shopping motivation” lead to impulse shopping through the formation of “positive emotion” in the context of airport duty-free shops.

A questionnaire-based survey was conducted in this study. The data collection for this study targeted individuals who had previously used airline services for international travel and visited duty-free shops at international airports. A total of 502 valid subjects participated in this survey.

The findings indicated that time pressure and consumers’ hedonic motivations have a positive impact on emotions. Positive emotions have a positive impact on the occurrence of impulse purchases. Music and light can moderate the impact of hedonic motivation on emotion but cannot reduce the influence of time pressure on emotion. Social factor significantly moderates the positive association between hedonic shopping motivation and emotion.

The research collected data from various international airports and social media, enabling the findings to be generalised.

To generate electricity, solar photovoltaic (PV) systems are among the best, most eco-friendly and most cost-effective solutions available. Extraction of maximum possible electricity from the solar PV system is complicated by a number of factors brought on by the ever-changing weather conditions under which it must operate. Many conventional and evolutionary algorithm-based maximum power point tracking (MPPT) techniques have the limitation of not being able to extract maximum power under partial shade and rapidly varying irradiance. Hence, the purpose of this paper is to propose a novel hybrid slime mould assisted with perturb and observe (P&O) global MPPT technique (HSMO) for the hybrid bridge link-honey comb (BL-HC) configured PV system to enhance the better maximum power during dynamic and steady state operations within less time.

In this method, a hybridization of two algorithms is proposed to track the true with faster convergence under PSCs. Initially, the slime mould optimization (SMO) algorithm is initiated for exploration of optimum duty cycles and later P&O algorithm is initiated for exploitation of global duty cycle for the DC–DC converter to operate at GMPP and for fast convergence.

The effectiveness of the proposed HSMO MPPT is compared with adaptive coefficient particle swarm optimization (ACPSO), flower pollination algorithm and SMO MPPT techniques in terms of tracked GMPP, convergence time/tracking speed and efficacy under six complex partial shading conditions. From the results, it is noticed that the proposed algorithm tracks the true GMPP under most of the shading conditions with less tracking time when compared to other MPPT techniques.

This paper proposes a novel hybrid slime mould assisted with perturb and observe (P&O) global MPPT technique (HSMO) for the hybrid BL-HC configured PV system enhance the better maximum power under partial shading conditions (PSCs). This method operated in two stages as SMO for exploration and P&O for exploitation for faster convergence and to track true GMPP under PSCs. The proposed approach largely improves the performance of the MPP tracking of the PV systems. Initially, the proposed MPPT technique is simulated in MATLAB/Simulink environment. Furthermore, an experimental setup has been designed and implemented. Simulation results obtained are validated through experimental results which prove the viability of the proposed technique for an efficient green energy solution.

This paper aim to analyse the motives behind the commitment of nurses to their profession despite their intense job duties during the COVID-19 pandemic.

The empirical sample comprises of 35 semi-structured interviews with public sector hospital nurses in under-researched contexts of Egypt and Peru.

Three types of motives were found to play a critical role in nurses’ commitment to their profession despite the difficulties associated with extreme work conditions. These factors include cultural (religious values, governmental coercion), contextual (limited education, organisational support) and personal (good nurse identity, submissive nature) dimensions.

This paper is one of the pioneering works to link existing literature streams on career commitment, extreme jobs, extreme context and management under disruptions (particularly COVID-19) by analysing these aspects in the under-researched Peruvian and Egyptian contexts.

South Asia is a region urgently seeking development, although it has failed in regional integration. It is the second least integrated region regarding the number of Free Trade Agreements (FTAs) and can thus be recognised as a missing bloc in the global multilateral system. This study aims to focus on South Asian FTAs and explores the problems of the inter-relations and compatibility between the systemic and regional trade systems.

The study proposes a framework to benchmark the compatibility of South Asian FTAs with WTO rules. Primary data from 2000 to 2020, including descriptive analyses of reports, legal text of the FTAs, official documents and factual presentations, have been collected and analysed through thematic analysis using the proposed framework.

The study finds that, although South Asian FTAs meet most of the WTO requirements, they are not progressing toward facilitating and promoting trade. Data from 2000 to 2020 show us that South Asian FTAs have not significantly impacted trade between themselves. The study argues that, although South Asian FTAs fulfil some benchmarks, they show only a lukewarm interest in contributing to the international trading system as building blocs. It is therefore recommended that the case of South Asian trade liberalisation must be understood contextually and be given careful and exclusive attention by the WTO.

As such, this study is the first to claim that South Asian FTAs are not fully compatible with the WTO rules. They remain a missing regional bloc in the multilateral system, rather than a building bloc or a stumbling bloc, delaying the region’s opportunity to develop as a region and within the larger system.

This paper aims to present an improvement to the power quality of the grid by using a colliding body optimization (CBO) based proportional-integral (PI) compensated design for a grid-connected solar photovoltaic-fed brushless DC motor (BLDC)-driven water pumping system with a bidirectional power flow control. The system with bidirectional power flow allows driving the pump at full proportions uninterruptedly irrespective of the weather conditions and feeding a grid when water pumping is not required.

Here, power quality issue is taken care of by the optimal generation of the duty cycle of the voltage source converter. The duty cycle is optimally generated by optimal selection of the gains of the current controller (i.e. PI), with the CBO technique resulting in a nearly unity power factor as well as lower total harmonic distortion (THD) of input current. In the CBO technique, the gains of the PI controller are considered as agents and collide with each other to obtain the best value. The system is simulated using MATLAB/Simulink and validated in real time with OPAL RT simulator, OP5700.

It was found that the power quality of grid using the CBO technique has improved much better than the particle swarm optimization and Zeigler–Nichols approach. The bidirectional flow of control of VSC allowed for optimum resource utilization and full capacity of water pumping whatever may be weather conditions.

Improved power quality of grid by optimally generation of the duty cycle for the proposed system. A unit vector tamplate generation technique is used for bidirectional power transfer.

Money laundering (ML) is a major criminal offence stemming from unethical practices by personnel on the ground at Chattogram Port, an important import and export facility in Bangladesh. Because money can be more easily laundered through imports, it is necessary to investigate the dubious process in this sector. This study aims to identify the items most regularly used for easy ML and the factors contributing to their vulnerability.

This research uses a qualitative approach and analyses information from primary sources. Data is obtained from customs officials, port authority personnel, importers and customs brokers through semi-structured questionnaires. Although there are many techniques for ML, this study only found three most overwhelming: under-invoicing, over-invoicing and misdeclaration. A few case studies have been used based on newspaper reports and the internet to triangulate the qualitative data.

Four import items – food products, garments, capital machinery and chemicals – have a higher risk of ML. This study also revealed that money launderers prefer under-invoicing food and garment items. Misdeclaration is more commonly associated with capital machinery and chemical items. Over-invoicing, on the other hand, is only prevalent in government purchases. The port authorities need to pay particular attention to these issues.

As ML is an ongoing activity that changes over time, the findings of this research are circumscribed by the data collected at a single point in time. Additionally, this research did not consider alternative laundering methods.

The research results can provide a basis for creating effective anti-money laundering (AML) strategies to assist with sustainable economic growth.

Developing effective AML measures can help combat corruption and establish good governance in the country and support human well-being.

This paper presents original research findings based on technical analysis. The Chattogram Port Authority and the National Board of Revenue have accepted and used the main findings in a collaborative action plan to tackle ML. The Bangladesh Bank, the country’s central bank, has also incorporated the necessary guidelines and regulations into the Money Laundering Prevention Act, 2012.

The extant literature on work–life balance (WLB) has generally overlooked the interrelationship between leadership and WLB. Does leadership have any impact on employees' use of WLB policies and practices? To answer this question, this article considers the social exchange theory as well as transformational and transactional leadership in an investigation of the impact of leadership on WLB.

The study employs qualitative data from 32 semi-structured interviews to achieve the study’s objectives.

The research reveals that leadership does matter in WLB. The study findings reveal that both the transactional and transformational leadership styles result in the establishment of strong reciprocal relationships between leaders and employees in terms of using WLB policies and practices. Managers only sanction the use of WLB policies and practices only as a reward for excellent performance or when they are completely sure the outcome will favour the organisation. The study concludes that the desire to achieve WLB has often led many employees to go the extra mile in carrying out their work duties, which is rewarded with an approval to use WLB policies and practices. These non-contractual exchanges emphasise reciprocity and are based on trust.

The extent to which the findings of this research can be generalised is constrained by the size and nature of the research sample.

Many managers are transactional leaders, and they purposefully allow their employees to use WLB policies and practices only as a reward for meeting targets and for excellent performance. This means that employees who fall short of the required targets and expected performance are not permitted to use WLB policies and practices. This finding implies that such employees experience incessant work–family conflict, which may have negative implications for their work engagement, overall well-being and work performance.

This study demonstrates that leadership is relevant to WLB. It shows that transformational leadership is supportive of WLB, as it considers employees' work performance and non-work outcomes. The results and practical implications of this study aids the understanding of the non-contractual exchanges involved in manager–employee relationships, which is crucial for ensuring employees' achievement of WLB and for organisations to achieve their goals.

The need to develop effective approaches for responding to healthcare incidents for the purpose of learning and improving patient safety has been recognised in current national policy. However, research into this topic is limited. This study aims to explore the perspectives of professionals in mental health trusts in England about what works well and what could be done better when implementing serious incident management systems.

This was a qualitative study using semi-structured interviews. In total, 15 participants were recruited, comprising patient safety managers, serious incident investigators and executive directors, from five mental health trusts in England. The interview data were analysed using a qualitative-descriptive approach to develop meaningful themes. Quotes were selected and presented based on their representation of the data.

Participants were dissatisfied with current systems to manage serious incidents, including the root cause analysis approach, which they felt were not adequate for assisting learning and improvement. They described concerns about the capability of serious incident investigators, which was felt to impact on the quality of investigations. Processes to support people adversely affected by serious incidents were felt to be an important part of incident management systems to maximise the learning impact of investigations.

Findings of this study provide translatable implications for mental health trusts and policymakers, informed by insights into how current approaches for learning from healthcare incidents can be transformed. Further research will build a more comprehensive understanding of mechanisms for responding to healthcare incidents.

This article aims to provide a new paradigm for thinking about disability, which can be applied to other social groups, historically invisible and whose rights have been violated. The Model of Communication and Legitimate Acknowledgement of Disability (MCLAD) tries to break with the logic of continuing to add terms and euphemisms around the issue. The author proposes a new line to think about relationships in democratic societies. Taking the step from inclusion to acknowledgment does not imply another way of naming the disability, but rather addressing the problem from concrete practices of recognition. In order to arrive at the proposal of the MCLAD, the author will make a journey that addresses how disability has been understood throughout history, according to the study of different authors.

Disability has been perceived over time in many different ways, which led some authors to build models in order to explain certain social approaches to the subject. This article traces a journey from the first model to the present. In turn, it proposes a new one: the MCLAD, which is characterized by a paradigm shift: moving from inclusion to acknowledgment. To substantiate this, three categories are presented: acknowledgment, distance and vulnerability. The different theories and concepts that support the model will also be presented. The purpose of the MCLAD is to deepen the idea of empowering people with disabilities as part of today’s diverse societies and closing historically constructed gaps which are still in force.

The MCLAD proposes three categories: acknowledgment, distance and vulnerability. In turn, in each of them, there is a link between three axes: person with disability/society/state, analyzing the dynamics of these relationships presented, will provide us with the necessary elements to understand the proposed turnaround.

Although the different models will be presented according to the chronological order of definition over time, all of them still coexist today, in many cases in hybrid and naturalized ways in social practices. Recognizing what practices and conceptions are behind each model, allows us to recognize and resignify the ways of communicating toward people with disabilities (PWD) and on the issue of disability. It also allows other specific recognition practices, such as the legitimization of public policies from the laws that protect them.

To replace the paradigm of inclusion for that of acknowledgment and to recognize how the three categories (acknowledgment, distance and vulnerability) are linked with the three issues (PWD – society and state) allowing specific relationship and practises of legitimate or not acknowledgement. When the author affirms that the MCLAD implies a paradigm shift, the author means that it provides some elements from legitimate acknowledgment to complement aspects which inclusion does not address, and that the other models did not take into account. These are: the self-acknowledgment of people with disabilities and the sense of responsibility linked to empowerment; vulnerability as a category of reconciliation, which is typical of every human being; the contribution of the Phenomenology of the Among to think about how relationships and practices actually occur in society and, finally, the role of the state, which must watch over all its citizens, avoiding the distance between discourse (laws) and practices and, above all, avoiding exclusion from the system due to lack of monitoring of actions.

It should be noted that the MCLAD starts from the idea of language as a constructor of realities and conceives communication as an enabler of the acknowledgment of the other, who is also subject to rights. At the same time, it vindicates the voice of people with disabilities as protagonists (“Nothing about us without us”) and fosters the need for PWD themselves to be active in their struggles, promulgating legitimate acknowledgment. At the same time, it points out that the empowerment of PWD implies not only that they are aware of their rights but also that they themselves know and fulfill their duties within the democratic societies of which they are a part of and which, at least discursively, are regulated by laws. In other words, being empowered is also being responsible for living in society.

The main contribution that the MCLAD has to offer is to replace the paradigm of inclusion for that of acknowledgment. And, throughout the path followed in this article, an attempt has been made to establish that the turnaround is not to capriciously install a new concept (acknowledgment), but to demonstrate that the new paradigm involves three categories that sustain and support a model that seeks to be the basis for effective public policies, for a society that values diversity and for people who feel worthy and contribute to dignify others.

This paper aims to examine the options available to arbitrators when they suspect money laundering during arbitration proceedings, considering their compatibility with fundamental principles and concepts of arbitration.

Using a doctrinal analysis approach, the paper draws on legal principles, antimoney laundering regulations and relevant literature to explore the topic. It considers relevant international treaties, standards set by the financial action task force on money laundering, cases and arguments from legal analysts and experts.

The paper identifies three options for arbitrators: disregarding suspicions, initiating an investigation or terminating the proceedings. Disregarding suspicions is deemed inappropriate, as it may facilitate the concealment of financial crimes. Initiating an investigation is seen as a preferable option, aligning with the arbitrator’s role and the public interest in nullifying contracts linked to criminal conduct. Terminating the proceedings is not recommended, as it contradicts the principle of natural justice. The paper emphasizes the importance of reasonable grounds for suspicions, notifying the parties, and allowing them to address the concerns.

This paper contributes to the existing literature by comprehensively analyzing the compatibility of these options with arbitration principles and concepts. It underscores the need for clear laws and directives to guide arbitrators in addressing financial crimes within the arbitration process, maintaining a balance between party autonomy and preventing the misuse of arbitration for illicit activities.
