In the last year or so, the cryptocurrencies market has seen significant fluctuations, which, according to research in the International Journal of Blockchains and Cryptocurrencies, has led to surge in influencer activity on social media. However, Sijie Yu and Jon Padfield of Purdue University in West Lafayette, Indiana, USA, point out that despite this increased activity there has been little academic research into the behaviour and impact of cryptocurrency influencers.

The team has endeavoured to fill this gap in our knowledge and has looked at how such influencers – usually individuals, but sometimes organisations, with large numbers of highly engaged followers on social media – affect perception and use of cryptocurrencies. The researchers have explored the classification and impact of influencers based on various metrics such as platform statistics, psychological traits, update content (specifically on the X platform formerly known as Twitter), social connectivity, and cryptocurrency price fluctuations. The researchers have also looked at how decentralized social media platforms have emerged following the change of Twitter ownership and its rebranding as X. Their review highlights some of the unique monetization models that shape influencer activities.

The way in which the cryptocurrency landscape has changed recently with financial approvals, settlements, news platforms, and novel approaches has led many people to turn to influencers for information and advice. Many of these influencers have such large followings and such sway that their online pronouncements are known to affect digital currency values, the value of digital assets known as NFTs (non-fungible tokens), and influence market trends.

The researchers point out that given the influence of such individuals, there is a lot of interest in the ethical and legal aspects of their activities. Much of their behaviour may be beyond the grasp of regulators, but some are being called to account when they fail to declare conflicts of interest in promoting schemes and assets. The current review offers policymakers, regulators, and enforcement, a detailed technical guide for profiling and identifying cryptocurrency influencers. This will allow them to analyse influencer social media content in a more informed manner and so apply the law forcefully.

Research in the International Journal of Migration and Border Studies has looked at how government policies in Canada are affecting non-citizen migrant youth in the country's child welfare system. The disheartening reality revealed by Mandeep Kaur Mucina of the University of Victoria, Abigail Lash-Ballew of the University of Toronto, Canada, is that the purportedly interconnected systems – child welfare, immigration, and criminal justice – are leading to ongoing instability for these people and systemic oppression.

The researchers looked at four youth who were formerly in the care system, who each live with precarious legal status. Their findings suggest that there is a transcarceral framework in place, a disturbing pipeline that funnels youth from welfare to incarceration and thence to deportation even where that is wholly inappropriate for a given case.

Canada is often celebrated for its inclusive stance towards migrants. However, this study shows a starkly different reality for non-citizen migrant youth. Without citizenship or permanent residency, these young individuals live under the constant threat of deportation, particularly when they come into contact with the criminal justice system. The team has looked at the lives of four young women as case studies of the issues and problems they face.

The research reveals deficiencies in the child welfare system that simply do not address the unique needs and rights of migrant youth. It also alludes to the psychological scars these young women bear, despite their successfully resisting deportation with the support of legal advocates and organizations. The harsh transition from protected child to being deemed a disposable adult fit only for incarceration and deportation makes criminals of innocent youth. The team, thus drawing attention to this crimmigration process, hopes to see policy changed so that the necessary care and support are at the forefront of the nation's approach to young migrants rather than the surveillance and marginalization that often frame these people as a threat.

Researchers in India have expanded the well-known theory of planned behaviour to obtain useful marketing and policy insights concerning the sustainability choices of consumers when it comes to food. The work, published in the International Journal of Sustainable Society, analysed data from 440 Indian households via self-administered questionnaires, which were then analysed using structural equation modelling. The addition of three variables – environmental knowledge, personal norms, and product attributes – not commonly used in traditional TPB model allowed the researchers to extract implications for various stakeholders, including producers, marketers, government agencies, and policymakers.

Priyanka Garg and Ashish Kumar of the Guru Gobind Singh Indraprastha University in New Delhi, and Raj Kumar Mittal of the Chaudhary Bansi Lal University in Haryana, India, demonstrated that their extended model could account for much of the variance in behavioural intentions. It showed that product attributes are the strongest predictor of sustainable food consumption behaviour. By contrast, and perhaps surprisingly, social norms had far less influence on the choices made by consumers. This, the team suggests, implies that factors such as food labelling, quality, and price must play a significant role in shaping choice rather than societal and peer pressure.

This research sits in the middle of growing global food and environmental crises. We are seeing continued population growth, environmental degradation and habitat loss, as well as the detrimental effects of climate change. As such, there are increasing pressures on agriculture and food resources. This is all despite, and perhaps in some ways, because of technological advances. There is a pressing need to shift our approach to food security towards more sustainable options. Sustainable dietary practices, including the consumption of local and plant-based foods rather than intensively produced meat products, could play a role in this. The side effects might even be a boost to our overall health, as well as a reduction in the environmental impact of food production. However, making such changes requires commitment and our ability to overcome many deeply ingrained cultural and social practices.

There is potential to change attitudes through clear, informative food labelling as well as educational campaigns to emphasize the benefits of sustainable food products. If marketing strategies can be aligned with addressing the ongoing crises, then consumer preferences might change and we could see the more widespread adoption of sustainable food choices. However, the market share for sustainable food products remains low. This suggests the need for a concerted effort from all stakeholders – producers, marketers, governments, and campaigners – to persuade consumers to make the sustainable choice.

The "five whys" technique is a problem-solving approach that involves repeatedly asking "why" to uncover the root cause of a failure. It is widely used in manufacturing, healthcare, information technology, aerospace and aviation, and in the service industries. However, it has limitations, not least a lack of understanding of how to use the approach correctly. Research in the International Journal of Six Sigma and Competitive Advantage has now looked at how the method can be used as either a superficial brainstorming tool or a rigorous investigative process and that understanding the approach in detail is essential to good quality control and safety in many different sectors.

The "five whys" is the modus operandi of many a root-cause analysis. It is a systematic approach that can be used to identify the causes of a given problem or failure so that a recurrence might be prevented. Matthew Barsalou of QPLUS in Manama, Bahrain, Beata Starzynska of Poznan University of Technology in Poznan, and Maria Konrad of Spawmet Zbigniew Kaczmarek in Ostrów Wielkopolski, Poland, explain that the efficacy of the "five whys" method works by alternating between asking "why" and conducting empirical investigations to validate each cause identified. For instance, if a bolt breaks and the answer to the question "why?" is simply because it was a weak or faulty bolt, then simply replacing it with a stronger bolt may well fail to address the underlying issue if the true cause of the bolt's demise was vibration in the system. The correct use of the "five whys" ensures that the underlying cause is found and mitigated.

The team has carried out a comprehensive review of the literature in this area and categorized the descriptions of the "five whys" problem-solving approach into three distinct groups. The first is the simplified approach that merely asks why without empirical evidence. The second is the empirical approach that requires actual investigation following each "why?". The third is ambiguous use, where the item in the research literature was unclear as to the precise usage of the method. The researchers found that more than half of the research literature described the "five whys" as a simple brainstorming tool. Only a minority highlighted the necessity of empirical investigation to validate each step.

The team followed up their review by surveying organisations about their use of the "five whys" method. This survey vindicated the review findings to reveal that many organisations simply used the "five whys" as a brainstorming method rather than an investigative approach. However, they note that those organisations that used the method frequently were more likely to recognize the importance of thorough investigation to back up the answer to each question "why?"

The problem that is obvious in retrospect is that the approach is being misused widely, leading to ineffective solutions and unresolved issues. Brainstorming alone is usually insufficient to identify the true cause of a problem, whereas empirical investigation after each "why" ensures solutions are based on verified causes, leading to more reliable and effective problem-solving.

Research in the International Journal of Mining and Mineral Engineering introduces a new approach to controlling mineral processing that uses active sensing. This method embeds intelligence within sensor systems, significantly reducing the need for human intervention in the process to improve efficiency and precision in mineral separation processes. Even tiny improvements in efficiency can have a major economic impact on processing of ores containing copper, lead, and zinc, and even more so in the case of precious metals.

Active sensing involves the integration of intelligent sensor systems that minimize human involvement by optimizing measurement processes. These systems use a combination of different measurements to put detailed information into the broader context. Primary measurements are precise but limited in range while auxiliary measurements provide broader, but more diffuse, data that can be used to guide the primary sensors to specific areas of interest that need detailed measurements.

Mikko Salo, Teijo Juntunen, and Risto Ritala of Tampere University in Tampere, Finland, have looked at this approach for froth flotation, an important process used in mineral processing. Froth flotation separates minerals based on how they interact with water, their water-repellent, or hydrophobic, character. A slurry of mixed minerals and water is treated with reagents to make certain particles hydrophobic, this makes them accumulate on air bubbles and so rise to the surface as froth. This froth containing much of the mineral of interest from the slurry can be scooped off as concentrate for further purification and processing. The remaining slurry, known as tailings, flows out of the system.

In most contexts, X-ray fluorescence (XRF) analysis is used to measure mineral concentrations in froth flotation. While XRF is precise, it is slow and expensive. It also only works sequentially, typically measuring multiple slurry lines one after the other, which also reduces efficiency.

As a cost-effective alternative, visible and near-infrared (VNIR) spectral measurements might be used. VNIR measurements works faster, with one measurement every three seconds, instead of one every five minutes with XRF. But VNIR data is less accurate than XRF and needs continuous calibration based on XRF data.

To overcome these limitations, the researchers have developed a control architecture using a linear quadratic Gaussian (LQG) controller with exception handling. They have used a simulated environment with plant data from the froth flotation process to test this approach. They demonstrated that the architecture optimizes the measurement sequence and incorporates interruptions when VNIR data detects anomalies. This ensures timely and accurate responses to process disturbances.

Research in the International Journal of Management Practice has looked at the relationship between job stress and well-being in people who are pet owners. The work suggests that pets can play a significant part in their owners' lives beyond the obvious role of owning a pet. Jehn-Yih Wong, Ying-Ying Cheng, Chia-Ying ChouHua, and Shih-Hao Liu of Ming Chuan University in Taipei, Taiwan, surveyed 228 pet owners in order to investigate how job stress impacts life satisfaction and emotional exhaustion and to determine whether a strong attachment with a pet can ameliorate these potentially detrimental effects.

Job stress is defined as anxiety, dissatisfaction and other negative emotions associated with one's work. They can all affect emotional and physical health. The researchers reiterate earlier findings that found that high levels of job stress are linked to decreased life satisfaction and increased emotional exhaustion. They raise the idea of coping mechanisms and used structural equation modelling and multi-group analysis to tease out the relationships better pet owners with a strong emotional attachment to their animals and job stress.

Intriguingly, the team found that while pet attachment did not actually influence a person's overall life satisfaction, it had an effect on emotional exhaustion in those suffering job stress. Pet owners with stronger attachments to their pets actually reported higher levels of emotional exhaustion than those with weaker attachments. This seems to be a counterintuitive finding that suggests that while pets provide significant companionship and emotional support, a deeper attachment may also amplify the emotional burden during stressful periods. Conversely, it might be that those people with strong attachments to their pets are more likely to be in touch with their emotions and able to recognise and express that kind of exhaustion more readily than others.

Less paradoxically, those pet owners who felt a strong bond with their pets did report that the negative impact of job stress on life satisfaction was less pronounced. Similarly, the reported greater emotional exhaustion associated with job stress in those people was somewhat mitigated by having a pet. This indicates that pet attachment can serve as a form of social support, helping to buffer against the adverse effects of stress in a manner similar to support from close human relationships.

A study in the European Journal of International Management sheds light on gender differences in how job embeddedness affects expatriates. This is especially true when individual face unexpected challenges, the research suggests.

Job embeddedness theory says that individuals who feel a strong sense of integration with their work environment and community are less inclined to leave their jobs, even during difficult times. The theory hinges on three primary dimensions: fit, links, and sacrifices. "Fit" describes the alignment an individual feels with their job and community. "Links" refer to their interpersonal connections, both at work and within the community. "Sacrifices" are the perceived costs associated with leaving their current environment. The more embedded someone is in terms of these various factors, the less likely they are to leave their job, particularly when they face unexpected events, "external shocks", that might prompt them to reconsider their position.

Sonja Sperber of Vienna University of Economics and Business in Vienna, Austria and Christian Linder of the University of Côte d'Azur, Suresnes, France, explain that research in this area has tended to focus on male expatriates. As such, there is an obvious and significant gap in our understanding of job embeddedness. The team hopes to begin to fill this gap. They have analysed data from expatriates in the United Kingdom and used Qualitative Comparative Analysis (QCA) to identify what factors influence employment turnover intentions among male and female expatriates having faced some kind of shock.

Migration and the movement of skilled female workers in particular has become an important trend in recent years and is not expected to decline. It is known that many female expatriates face issues not experienced by their male counterparts. Many of these issues are associated with why they have migrated, the cultural adjustments they must make, the balancing of family responsibilities, and the management of gender stereotypes. These factors can affect their experience and also whether they choose to remain in their position when faced with shocks.

The team found that the concept of "fit" appears to be more crucial for female expatriates. This suggests that women tend to prioritize how well they align with their job and community. In contrast, male expatriates apparently emphasize the "sacrifices" involved in leaving their job, indicating a greater focus on the costs of leaving their current position.

Such differences point to a need to consider gender-specific perspectives in job embeddedness theory and human resource management practices. Understanding the differences will allow HR managers and others to develop more nuanced and effective support mechanisms for expatriate employees. A one-size-fits-all approach is wholly inadequate, the work would suggest. Gender-sensitive human resource policies could be critical in helping expatriate employees cope with shocks, and at the same time help organizations with the retention of their skilled international workforce.

Cross-border e-commerce has transformed international trade. Nowhere are the changes more keenly felt than in China where e-commerce has moved business away from traditional, large-scale trade towards more fragmented, personalized, and frequent transactions. Small and medium-sized enterprises (SMEs) along with solo entrepreneurs are now at the forefront of this change.

Banban Mao of Hunan Vocational College of Commerce and Hua Tian of the Hunan International Economics University, China, discuss the impact of this change on the "green" food industry. The sector focuses on environmentally friendly and sustainable food production and has embraced technology such as "big data" and collaborative innovation where information sharing and coordination across the entire supply chain, from producer to retailer is critical to success. Writing in the International Journal of Information and Communication Technology, the team discusses how the implementation of intelligent supply chain collaboration and the integration of online and offline operations can allow the green food industry to respond more effectively to market demands and the evolving internet economy.

The team points out that these changes have not been without their challenges. The rapid rise of cross-border e-commerce has meant an increased reliance on third-party platforms, and this builds information silos and complicates data sharing and transparency. The researchers add that the complex nature of the supply chain also makes it difficult to verify product legitimacy and quality as well as adding logistical challenges that reduce efficiency.

Additionally, high cross-border payment costs and security risks, coupled with the various international regulations and legal standards, add obstacles to what might otherwise be seamless trade operations.

Blockchain technology might well offer a way to address many of these problems. Blockchain provides a secure and transparent method for recording transactions and sharing information. Thus, by establishing a cross-border e-commerce alliance chain, blockchain could be used to streamline intermediary processes and enhance trust among participants. The research demonstrates how technology might add value to the green food supply chain.

Education has already been transformed radically by technological advancements and by societal changes. Traditional, classroom and lecture-based models have evolved into more interactive and engaging approaches. However, challenges remain, and the student experience is not always as they and their educators might hope for. A study in the International Journal of Information and Communication Technology has looked at how virtual reality (VR) technology might be integrated with Internet of Things (IoT) teaching platforms to create a more immersive and interactive educational experience for certain parts of the curriculum.

Dafei Wu of the School of Information Engineering at Hunan University of Science and Engineering in Yongzhou, Hunan, China discusses how VR technology provides an immersive environment and could for many students enhance traditional teaching methods by offering a dynamic and engaging platform. When combined with the IoT that allows interconnected devices to interact with their environment and exchange data, the potential of VR might be opened up even further, changing how educational content might be delivered and so experienced.

Wu suggests that this kind of integration could lead to novel teaching methods paradigm to the benefit of students. It might even be tailored to be more closely aligned with society and industry requirements from the educational system. Conventional teaching methods often keep theoretical and practical learning separate, the world of VR technology coupled with the IoT might help better support teaching objectives and student development.

Fundamentally, with such an approach, students might access course materials and engage with content at any time and anywhere, thus allowing them to experience continuous learning and develop skills at their own pace within the overall educational framework. This, Wu suggests, might be particularly useful on courses where the demand for resources often exceeds availability.

"Simulation results demonstrate VR's extensive applicability, offering a broader and more open educational platform," concludes Wu. He adds that "Future endeavours should focus on effectively combining immersive IoT with higher education to enhance educational outcomes."

Recent upheavals in the global market have put supply chains under immense pressure and the logistics and road transportation sectors are struggling to keep apace with geopolitical tensions, rampant inflation, and the rising demand for sustainability as well as many other issues. Rising energy costs and a shortage of qualified drivers are also adding to the burden. Research in the International Journal of Industrial and Systems Engineering has looked at the potential for Horizontal Logistics Collaboration to overcome many of the problems.

Taher Ahmadi, Jack A.A. van der Veen, and V. Venugopal of the Nyenrode Business Universiteit in Breukelen, The Netherlands, and Mehdi A. Kamran of the German University of Technology in Oman, Muscat, Oman, discuss how HLC involves different companies combining their transportation or logistics activities to mutual benefit in the face of the afore-mentioned growing challenges. This strategy aims to enhance economic, social, and environmental outcomes by optimizing the use of vehicles and so reduce transportation costs as well as carbon emissions.

However, while the theoretical benefits of HLC are well-documented, practical implementation has not lived up to expectations, the work suggests. The main obstacle is a lack of understanding regarding the hidden coordination costs, particularly those associated with inventory and warehousing.

The new study has investigated the complexities of HLC and developed a quantitative model of two supply chains. Each supply chain includes a single buyer and supplier situated in different regions. The model then compares and contrasts two scenarios: a standalone case in which each buyer manages transportation independently, and a second HLC scenario wherein the buyers coordinate inventory replenishments and deliveries using shared transport vehicles.

The team found that while the HLC scenario did reduce transportation costs and carbon emissions, it also introduced a downside in terms of higher warehousing costs. This increase stemmed from the need for synchronized, but less-than-optimal, ordering frequencies. The extra warehousing costs could negate the benefits of HLC as well as adding a layer of complexity to the decision-making process for companies considering this collaborative approach.

Nevertheless, the study shows just how important it is to evaluate the total costs for transportation and warehousing, rather than simply focusing on the potential transportation savings. Of course, there may well be ways to optimize such an approach and make it work better for all parties involved. If collaborating parties can mesh more effectively in terms of geographic proximity and order frequency, then they might gain all the pros with much-reduced cons of HLC.
