Formula 1 (F1) is the highest level of international motorsport, known for its fast, high-performance, single-seat racing cars. It is governed by the Fédération Internationale de l'Automobile (FIA), and features a series of races, Grands Prix, held on racing circuits worldwide. The races are known for their speed, technical precision, and intense strategy.
A study in the International Journal of Automotive Technology and Management discusses how this global racing series acts as a real-time laboratory that can test and refine motoring technologies that often take a turn into the world of the road vehicles. In other words, Laura Rehberg of the Institute of Entrepreneurship and Innovation Science at the University of Stuttgart, Germany, suggests, F1 is in the driving seat when it comes to shaping the future of the automotive industry.
Rehberg has investigated the world of prototyping within F1 showing how car manufacturers and their suppliers collaborate with one of the most competitive sporting environments. Prototyping refers to the stage in development where experimental versions of components are created and tested. Often, new technologies are pushed to their limits in this environment before they ever go into production. Within F1, prototyping is high-pressure, with the requisite innovation being relentless and having the drive to cut seconds off lap times. Of course, innovation is constrained by the strict FIA regulations, but some important inventions have emerged from F1 innovation, and many of those, such as mild-hybrid vehicles, were actually driven by the regulations themselves.
It is the collaboration between original equipment manufacturers (OEMs), the carmakers, their suppliers, and the F1 teams that at the heart of Rehberg's work. The research shows that the sport has pulled away from the conventional, arms-length relationships and a change of gear has led to "collaborative prototyping," where suppliers are not merely vendors but partners, contributing to the design and testing process itself. Such integration allows for more rapid innovation and precludes many of the costly mistakes that can occur later in development when innovation moves on to the production line. Innovations in engine efficiency, vehicle aerodynamics, and materials science are all tested to the extreme in F1 and many developments that have improved times and fuel efficiency on the racing track have act as a catalyst for production cars to hit the roads.

DOI: 10.1504/IJATM.2024.142122 - An algorithmic approach to healthy eating
Diet plays an important role in health. A study in the International Journal of Business and Systems Research has looked closely at the relationship between nutrition and the prevention of chronic diseases such as diabetes, cardiovascular disease, and cancer. It is worth noting that despite increasing public awareness of the link between poor diet and disease, many people struggle to make healthy choices for themselves.
The researchers, Suvendu Kumar Nayak, Sangram Keshari Swain, of Centurion University of Technology and Management, Mamata Garanayak Kalinga of the Deemed to be University, and Bijay Kumar Paikaray of the Siksha 'O' Anusandhan (Deemed to be) University, Odisha, India, point out that tracking food intake and nutritional value and making informed dietary choices can be overwhelming. This then can lead to bad habits that contribute to the risk of chronic illness.
In recognizing this gap between information and application and nutritional awareness, the researchers have proposed a new approach to offering personalized dietary advice that is tailored to individual health profiles and preferences. Their system determines a patient's nutritional needs in conjunction with their medical history and current health conditions using the K-Nearest Neighbours (K-NN) algorithm. The algorithm, trained on data from a range of people with different conditions and dietary requirements, allows it to find the optimal diet most beneficial to the current patient.
The team explains that by introducing a structured approach to nutrition using their approach, it might be possible to reduce the dietary risk factors associated with many chronic diseases. This could improve health for individuals but also lower the burden on healthcare systems. There is already a growing trend towards personalized healthcare, such as fitness trackers and other health apps, the addition of dietary tools will help guide those individuals who hope to improve their health in these and other ways.

DOI: 10.1504/IJBSR.2024.142053 - Wear and care
Wearable technology is well known to anyone with a fitness tracker but it is also moving into critical care medicine. Research in the International Journal of Systems, Control and Communications has looked at how wearables might change the management of patients in intensive care units (ICUs). Such devices can provide continuous, real-time data for healthcare professionals following the vital signs and movements of critically ill patients. The technology might offer a more personalized and less invasive approach to treatment.
Decheng Fan of the University of Shanghai for Science and Technology, Junmin Li and Jingjing Fang of The Second Military Medical University, Jianbo Su of Shanghai Jiao Tong University, Shanghai, China, explain that conventional ICU monitoring usually relies on bulky equipment such as heart monitors, devices for monitoring respiratory function, and measuring blood pressure, for instance. These methods, while effective, usually require active and regular intervention from the healthcare workers. There is also usually a need for taking samples of blood and urine etc, which is usually invasive and carries a risk of introducing infection.
Wearable technology could offer a viable alternative to the more intrusive and invasive technologies that have been used for many years. One of the biggest benefits is the non-invasive and continuous monitoring that wearables could offer. Wearables will support healthcare by transmitting personalized data to clinicians, allowing them to make decisions in real time to assist patients with complex, life-threatening conditions such as multi-organ failure.
Researchers are already working on multifunctional sensors that could be integrated into a single device to streamline the whole process of data assimilation and transmission. Such devices could be of great benefit in specialist care settings where resources are scarce, such as during a pandemic, for instance.

DOI: 10.1504/IJSCC.2024.141395 - Please take a seat for your virtual interview
There is seemingly no endeavour untouched by the potential of algorithms and artificial intelligence. Writing in the International Journal of Communication Networks and Distributed Systems, a Czech team discusses the potential for chatbots to carry out initial job interviews with candidates.
A chatbot-mediated screening process could allow wholly unsuitable candidates to be quickly removed from the short list so that interviewers can focus on those applicants best suited to the role being sought. Such a change in the way recruitment is undertaken raises ethical issues about just how fair is screening job applicants in this way, especially given many of the known problems surrounding algorithm training bias and other issues that have been raised about artificial intelligence carrying out human jobs.
Insights from the research could help guide exactly how companies approach recruitment in the wake of these intriguing technological developments. There are three important aspects that Helena Repová, Jan Zouhar, and Pavel Král of Prague University of Economics and Business consider in their paper: procedural justice, in other words, fairness in decision-making, interactional justice, fairness in how candidates are treated, and interpersonal justice, the quality of personal interaction.
The researchers compared applicant perceptions of these forms of justice across different interview formats, including interviews conducted by humans, chatbots, and those where the interview type wasn't revealed.
Chatbots offer a clear efficiency advantage to companies in screening applicants. But, for applicants accustomed to conventional interviews, issues of fairness, or a lack thereof, are apparent. Indeed, an applicant's perception of justice in recruitment might alter their opinion of the organization itself and deter bright and well-suited applicants from applying for a position with a given company in the first place based on that company using chatbots for initial interviews. Companies could miss out on talent and the talented candidates could miss out on their dream role!

DOI: 10.1504/IJCNDS.2024.141672 - Gleefully pitch perfect
A powerful algorithm that can automatically classify different singing voices by vocal characteristics is described in the International Journal of Bio-Inspired Computation. Balachandra Kumaraswamy of the B.M.S. College of Engineering in Bangalore, India, suggests that the development is an important step forward in music technology, allowing a system to quickly and accurately distinguish one voice from another without human intervention.
Everyone's singing voice is shaped by a range of physiological characteristics such as their vocal folds, lung capacity and diaphragm, the shape of their nose and mouth, the tongue and teeth, and more. Add to that the emotional delivery and stylistic choices a singer might make, and each of us sounds unique. It is fairly easy for us to tell singers apart, even if the singing is within a complex and textured musical environment. However, using machine learning to distinguish voices has remained challenging. Kumaraswamy's system performs well and could be employed in a wide range of contexts such as music cataloguing, streaming, recommendation, music production, and even for legal purposes such as copyright control.
The new approach takes four steps to distinguish between singers. The first is pre-processing in which an advanced convolutional neural network (CNN) identifies and isolates the vocals from a complex audio recording, discarding instrumentation and other non-vocal sounds.
The second step is feature extraction whereby key characteristics of the voice are obtained from the audio track and various metrics, such as the zero crossing rate (ZCR), which measures the frequency of signal changes, capture the characteristics of the singer's voice.
The third step involves an algorithm identifying the vibration patterns of the notes being sung and so can create a profile distribution of the harmonics to map the timbre, or texture, of the voice.
The final step used yet more neural networking in the form of bidirectional gated recurrent units (BI-GRU) and long short-term memory (LSTM) networks to analyse the vocal data. These two models can process sequences and so reveal the flow of a singer's performance over time. This last step is key to the success of Kumaraswamy's approach.
At this point in the development of the system, the neural networks used require extensive computational resources and large datasets for training. For now, this might limit scalability. However, such issues can be addressed with optimisation of the way the algorithms are applied and the training data used.

DOI: 10.1504/IJBIC.2024.141676 - The left and right of recycled price tags
The sale of refurbished products, refurbs, represents a delicate balancing act for companies attempting to retain a share of their market and to incorporate recycling strategies into their approach. A study in the European Journal of Industrial Engineering discusses this balancing act in the context of new and refurbished sales, where consumers weigh affordability against quality.
According to Yeu-Shiang Huang of National Cheng Kung University, Taiwan, Chih-Chiang of Zhaoqing University, China, and Yi-Hsiang Tsao of the National Cheng Kung University, Taiwan, businesses must decide how to stay competitive while addressing environmental concerns. The team has used game theory to model the kinds of decisions that retailers must make and offers them tips on that balancing act.
Selling refurbished as opposed to brand-new products, especially electronic gadgets and devices, represents a classic dilemma in economics. Refurbished products are usually sold at lower cost and so offer less profit for the retailer, but they might be more attractive to the consumer because they have eco-friendly credentials. Refurbs can thus undercut the sales of brand-new items. As such, manufacturers themselves remain hesitant in their adoption of remanufacturing, despite its environmental benefits. But, for retailers, offering refurbished goods can lead to a new class of sale.
The researchers have modelled the strategic interactions between manufacturers and retailers to look at how manufacturers set the official price for the wholesale cost of their new products, while retailers respond by adding refurbs to the mix and setting the best price for those and for the brand-new products they sell.
The research emphasises that it is the environmental rather than the economic that is at stake. Strict recycling laws mean that there is a drive towards refurbishment and recycling that the retailers can be happy with, but the original manufacturers may well not be. Indeed, if retailers can take control of recycling and remanufacturing and connect directly with the end consumers of refurbs, the manufacturers' share might shrink at least until the refurbished products have become wholly obsolete and can only be recycled for components and materials and a new product must enter the market. Retailers by working to their own economic strategy might thus play a critical role in driving sustainable practices.

DOI: 10.1504/EJIE.2024.141720 - Don't you know that you're toxic?
A comprehensive literature review in the International Journal of Process Management and Benchmarking sheds light on research into the notion of toxic leadership and how this increasingly pervasive issue affects the workplace and can damage organisations.
Emily Maria K. Jose and Bijay Prasad Kushwaha of the Vellore Institute of Technology, India, used a systematic approach to extract relevant research articles from a scholarly database. Their analysis of these papers revealed five principal characteristics of toxic leadership: authoritarian leadership, abusive supervision, narcissism, unpredictability, and maladjustment. Their findings highlight the nature of toxic leadership but also point to how it can affect employee engagement, performance, and retention.
Toxic leadership is defined as management behaviour that is ultimately harmful to both employees and the company for which they work. Toxic leaders are commonly indifferent to employee well-being and prioritize self-interest. The result is the creation of a working environment filled with fear and instability. The current review suggests that common toxic behaviour affects individual employees but also propagates through the corporate culture and so can affect an organisation deeply.
Jose and Kushwaha found that toxic leadership leads to high employee turnover rates. Indeed, almost three quarters of employees faced with toxic leadership will contemplate leaving their jobs. High staff turnover leads to a loss of team cohesion and other negative effects that will eventually have financial repercussions for the company if not remedied. Research suggests that toxic leadership can lead to almost a third of business failures each year.
The study discusses psychological safety and employee engagement, both of which can be affected negatively by toxic leadership. In a toxic work environment, employees become disenfranchised, which leads to a fall in their productivity and a deterioration of their work-life balance. A vicious cycle of dissatisfaction then feeds the toxic culture still further. There is thus a critical need for organisations to recognize and address this potentially destructive problem more proactively now than ever before. Effective coaching, constructive feedback, and monitoring should be key to mitigating the risks associated with toxic leadership behaviour, the research suggests.

DOI: 10.1504/IJPMB.2024.141538 - Doing good can boost the bottom line
Can companies do well by doing good? Research in the International Journal of Productivity and Quality Management that has looked at companies listed on the Tehran Stock Exchange (TSE) provides a positive answer to that question. The researchers found that there is a strong link between corporate social responsibility (CSR) and financial performance. They also suggest that risk management is an important mediator of this effect.
Nasrin Dadashi and Seyyed Saeb of the Islamic Azad University, Rasht, Iran, and Ali Mayeli of Stony Brook University, New York, USA, explain that CSR is a rather broad term that covers a company's ethical conduct and its contributions to society. It spans three areas: economic, social, and environmental. CSR is, they suggest, no longer about box-ticking, green-washing, or rubber-stamping, and goes hand-in-hand with a company's financial health as well reflecting investor confidence. The team demonstrated that those companies that embraced CSR saw significant improvements.
This, they emphasise, is only half the story. Risk management, specifically Enterprise Risk Management (ERM), also emerged from the work as a key factor in the overall equation. ERM involves identifying, assessing, and mitigating potential threats to a company's objectives, is nothing new, yet the study shows it to play an important part not only in enhancing CSR, but also in boosting the positive impact CSR has on financial performance. CSR is no longer merely a moral imperative. CSR is a strategic imperative.
The team suggests that the integration of CSR and ERM into a company's core strategies will not only build trust and reduce the information gap between the company and its stakeholders, but also position it better for long-term success financially speaking. From the investor perspective, these findings also carry significant weight. When money is so often the only matter arising on an investor's agenda, they could do well to consider an investment's CSR and ERM, as they emerge as good indicators of future performance.

DOI: 10.1504/IJPQM.2024.141493 - Mowing the green, green grass of social media
Social media is now rooted in the terrain of our daily lives. Research in the International Journal of Mobile Communications has looked at whether the psychological toll of our constant use of these tools and our comparing ourselves to others online is doing more harm than good. With the advent of always-on, ubiquitous messaging apps, we catch sight of more and more people participating in and enjoying the things we imagine we ourselves should be doing.
The notion of FOMO – fear of missing out – is always at the back of our minds even when other notions, detachment, acceptance, and mindfulness, are high on the mental health agenda. The researchers have studied the well known Chinese app WeChat and looked at the impact of social comparison and observed how it can go beyond merely influencing our thoughts and emotions but might shape online behaviour in unpredictable and putatively troubling ways.
Bao Dai of Hefei University of Technology, Anhui, and Lingling Yu and Ying of Shanghai University, Shanghai, China, explain that users of WeChat and similar apps often share highly curated, glossy snapshots of their lives. This leads others with perhaps less glamorous opportunities to experience envy and mental fatigue. Envy, in this context, refers to the unpleasant feeling that arises when individuals believe others are more successful, attractive, or happier than themselves. Fatigue, on the other hand, is the mental exhaustion that stems from constantly being bombarded with these idealized portrayals of life. Both emotions can act as catalysts, transforming the stress of comparison into tangible behavioural changes.
The team found that envy is much more detrimental than fatigue. Feeling like one is falling short can trigger a much stronger behavioural change that is not necessarily positive. They add that many users, overwhelmed by these emotions, choose to disengage. This disengagement takes two forms: discontinuance and information avoidance. Discontinuance is a full or partial withdrawal from the social media platform, where users cut back on their usage or quit entirely to avoid further emotional strain. Information avoidance, a more subtle but no less troubling response, occurs when users selectively filter out certain content and so avoid updates or posts that could reignite feelings of envy or inadequacy.
The research highlights the often hidden emotional price of staying connected in the digital age. While social media is lauded for its ability to foster communication and self-expression, it can also nurture environments where users feel more isolated or inferior. There is perhaps an urgent need for more research and for users and platform providers to address the darker side of digital connectivity.

DOI: 10.1504/IJMC.2024.140735 - Winter is coming…check the powerlines
Winter is coming and in many places with it the risk of ice accumulation on overhead power lines and all the problems that can lead to, including, in extreme cases, pylon collapse.
Writing in the International Journal of Energy Technology and Policy, a team from China describes a new approach to monitoring ice accumulation on power lines and pylons using unmanned aerial vehicles, drones, to acquire images of the infrastructure and image-processing algorithms to identify icy problems.
Yang Yang, Hongxia Wang, Meng Li, Minguan Zhao, Yuanhao Wan, and Shuyang Ma of Xinjiang Power Transmission, Urumqi, Shenbing Hua of China Electric Power Research Institute Co., Ltd., Qifei He of the Power Dispatch Control Center of State Grid Corporation of China, Beijing, China, suggest their work could improve winter safety and reliability of electricity networks. It has real implications for countries such as China where transmission lines cross vast and diverse terrains stretching across remote and largely inaccessible areas.
Conventional approaches to checking for dangerous ice accumulation have led operators to act either too conservatively and so undertaking unnecessary maintenance or less cautiously and too late, risking damage and power outages. The new method uses camera-equipped drones to capture live images of power lines and then applies compressive sensing theory to the images to remove environmental noise and clean the data for processing. The Canny algorithm is then applied to carry out advanced edge detection to reveal ice formation on power lines. A random Hough transform then finds the straight edges of the ice deposits and helps with calculations of the ice thickness to show which stretches of transmission lines are likely to be problematic.
With China's weather extremes, a better way to monitoring power lines in winter is crucial to keeping the lights on.
