The gift of tongues

One of my earliest memories of growing up as a bilingual child in the Philippines was that my siblings and I felt…well, rather special. The fact that from the age of two or three we could rattle off in French amongst ourselves, then within seconds and without a moment’s hesitation switch to English when addressing our relatives or friends around us, always seemed to enthral and impress some people. It was at times annoying though. Occasionally, my mother’s friends, who found it irresistibly cute that we could speak French, would squeeze our cheeks in delight and beg us to say something in French (anything!) even if they couldn’t understand a word we said.

People would frequently make a fuss. But despite the unwanted attention, we knew that not everyone around us could speak two languages fluently. Later on, when as a family we went to live in the French countryside for a few years, all my French classmates knew that my sister and I were the only ones who could speak English fluently, and because of this, we felt just a tad more unique. Nevertheless, during the early years of our childhood, being bilingual felt more like we had a cool party trick up our sleeve, rather than a useful and advantageous skill. It was only years later, as we started growing up, that we realised what a wonderful gift our parents had given us by striving to bring us up as bilingual and, eventually, multilingual children.

My Filipina mother, who spoke French fluently after studying at the Alliance Française in Manila and later on at the Sorbonne University in Paris, only met my French/Swiss expatriate father once she returned home to her native Manila. From the earliest years of their marriage, they decided that we would grow up to be at least bilingual in French and English, and ideally proficient in Tagalog (the other official language of the Philippines in addition to English). Thus, they proceeded to make French the main language of the family at home, and enrolled us in an English kindergarten in Manila to begin with.

As I grew up, I continued my schooling in France and, upon returning to the Philippines, first at the French School and later at the International School in Manila. I found it quite easy to pick up Spanish as an additional subject, because of its similarities to French and Tagalog. Subsequently, I went on to study Japanese at my university in Tokyo, and this opened up more doors for me throughout my career – including getting a dream job at Nike’s world headquarters in the United States. There, I picked up my sixth language, Portuguese, thanks to the work I did for Nike in Brazil. To this day, I credit my parents’ foresight and efforts in giving me this priceless gift of languages, which has granted me countless opportunities in my personal and professional life.

Today, as I contemplate raising my own multiracial children in multicultural Singapore, I am acutely aware that being bilingual or multilingual is becoming an increasingly widespread social phenomenon, governed by the trends of globalisation, immigration and the rapid rise of cross-cultural marriages. It is however interesting to observe that, historically, language exposure as a result of migration, conquest, colonisation and even slavery has created a multitude of sociolinguistic environments in which individuals have been exposed to other languages, besides their own mother tongue. In fact, the reality of today’s present world is that across most continents, multilingual speakers continue to outnumber monolinguals, making multilingualism the norm and monolingualism the exception.

Consequently, there was never a doubt in my mind that my own children would grow up speaking at least two languages, as I did.

I was determined to ensure that I would give them that advantage early on, no matter what. As I spent considerable time and energy researching and reading up on the subject of bilingualism and multilingualism, I came across a surprising controversy about whether growing up bilingual is an advantage or a disadvantage. The theory is that growing up bilingual is beneficial to a child’s development and cognitive skills, but many have come to question the idea because they believe that bilingual children end up without complete fluency in any language. Despite the historical facts pointing to the contrary, there have even been voices in the past claiming that raising bilingual children is something unnatural.

Nowadays, most linguists agree that these kinds of theories and myths are completely unfounded. In 1962, Elizabeth Peal and Wallace Lambert conducted one of the first studies of bilingualism in ten-year-old children from six schools in Montreal, Canada. Their study confirmed the positive influence of bilingualism. The results showed that ten-year-old bilinguals (French/English) performed far better on intellectual analytical tests than did monolinguals.

Since then, numerous studies on language development have corroborated these findings and demonstrated that being bilingual not only enhances our ability to understand and analyse concepts, but also increases our access to multiple perspectives in a multicultural society. Furthermore, growing up bilingual is not only the easiest way to learn a language, as it was for my siblings and me, but it also makes learning other languages much easier. The differences in sounds, word order, rhythm, intonation and grammatical construction in a new language are much easier to learn if you already speak a couple of languages. Indeed, bilingualism has been proven to help children develop overall better analytical and academic skills, than their monolingual peers.

Knowing more than one language facilitates a natural flexibility and adaptability, and boosts self-esteem and self-confidence, while increasing the appreciation and acceptance of other cultural differences. And when it comes to career prospects in most parts of the globe, as I found out myself, knowing more than one language has been established as an excellent way to increase your chances.

Furthermore, research conducted by a group in Concordia University in 2019 found growing evidence to suggest that bilingualism provides cognitive benefits such as better inhibitory control, and that it can be a protective factor against the onset of Alzheimer’s disease. Numerous studies have found that the onset of Alzheimer’s disease is delayed by 4-5 years in bilingual patients when compared to monolingual patients regardless of sex, lifestyle, education and occupation.

This being said, there are unfortunately still many people who could have grown up bilingual, but regretfully did not, because of the choices their own parents made to focus on a single language. Many immigrants, for instance, make a conscious effort to fit into their new country, and as a result prefer to concentrate on the language of the home nation at the expense of their native tongue. While these motivations are completely understandable, many children regret their parents’ decision in the long term. Besides having their child miss out on the great advantages of growing up bilingual, parents who don’t stimulate the learning of their own mother tongue are ensuring that their children lose a valuable cultural heritage and an important connection to their own roots.

Ultimately, the pros of being bilingual vastly outnumber the cons. And there are basically only four potential drawbacks to growing up bilingual, which are not even applicable in every case. They are: starting to speak later, mixing languages, the additional effort for the parents and the different levels of fluency in both languages (reading & writing vs only speaking, for instance). While it has been said that bilingual children, in some cases, begin speaking later (sometimes three to six months later) because they are learning two language systems at the same time, it is a small price to pay for the ability to grow up bilingual.

Mixing words is usually a temporary phenomenon, which tends to diminish by the age of four or five, or when vocabulary in each language augments. It is also true that raising a bilingual child is a big commitment and a long-term investment. It requires extra effort from the parents to ensure the right amount of language exposure and discipline to keep language rules consistent. But parents of bilingual children agree overwhelmingly that the benefits for their children are well worth the effort.

Lastly, reading and writing in two languages adds to the academic workload especially if the aim is complete fluency in both languages. It helps if the alphabet is the same, but often this is not the case, such as in Chinese and German for example. As a result, fluency in both languages actually hinges on many factors and varies depending on the individual’s own ability, commitment and, of course, on the chosen language’s degree of difficulty. And while it is possible for some individuals to be completely and equally fluent in two languages (speaking, reading and writing), it is not uncommon for some bilingual people to feel more comfortable writing or reading in one language rather than in the other.

Nevertheless, despite these numerous challenges, there is no doubt that multilingual children enjoy more advantages in their life as a result. My own four children are extremely fortunate to be growing up in multicultural Singapore, speaking French and English fluently. They are conversational in basic Tagalog, which we speak every day with our Filipina nanny at home. Spanish has spiked their curiosity too, as they are keenly aware of my many Spanish-speaking expatriate friends. And they chuckle and pride themselves about the fact they can already understand a little Spanish and Malay, because of the similarities with Tagalog (which is a blend of Malay and Spanish).

Additionally, my children have been studying Chinese for many years, while first attending the Lycée Français of Singapore in their primary school years, and then middle school and high school at the United World College of South East Asia (UWCSEA), one of the most diverse and culturally rich schools in the world. Even if they sometimes complain to me about how hard it is to learn Chinese, I remind them that one day, they will realise how privileged they all are to be exposed to such an important and valuable language. I promise them, as my parents promised me, that their hard work and efforts will give them an added advantage in life when it comes to both career and personal opportunities.

Bringing up bilingual or multilingual children takes some effort and determination, but the benefits vastly outweigh the difficulties and leads to cognitive benefits that will last their entire life. Learning a new language is not simply an additional practical skill, it offers a completely different vision and perspective of the world. While it opens up a whole new cultural appreciation, it sharpens our intellect and keeps our brain alert.

Speaking more than one language strengthens leadership skills by broadening the way people communicate, how they are perceived by their audience and how they connect with their own multilingual and multicultural teams. It has certainly helped me become a much more inclusive and empathetic leader, particularly given the diversity of my colleagues and teammates. And while attaining and maintaining fluency in any language takes tremendous commitment and discipline, in the end, couldn’t bilingualism – or multilingualism – be one of the greatest gifts you could offer your own children?

Creating new structured spin states with spatially structured polarized light

Spin, a quantum property of particles, can be controlled using light waves to store information.

This is conventionally achieved using a uniformly polarized light beam. Recently, researchers from Japan successfully generated a structured light beam with spatially variant polarization and transferred its structure to electron spins confined within a semiconductor solid. Additionally, they simultaneously generated two spin waves with inverted phases using this beam. Their results have important implications in optical communications and information storage.

Light is composed of electric and magnetic fields that oscillate perpendicular to each other. When these oscillations are restricted, say, along a plane, it results in polarized light. Polarized light is of great importance in optical communications and can similarly revolutionize how information is stored.

Current electronic devices store information in the form of electronic charge. However, spin – a uniquely quantum property of electrons – offers an alternative. The spin can be controlled using polarized light to store information. A polarized light beam interacts with electron spins within a semiconductor to generate spin-polarized electrons, i.e., spins aligned along a specific direction. So far, only uniformly polarized light, i.e., light with a spatially uniform polarization, has been exploited to control electron spins. If, however, the polarization has an additional spatial structure (variation), it can produce spatially structured electron spins, opening up new ways to store information.

To this end, a group of researchers, led by Junior Associate Professor Jun Ishihara from and including Graduate Student Takachika Mori, Graduate Student (at the time of the research) Takuya Suzuki, and Professor Kensuke Miyajima from Tokyo University of Science (TUS), Japan, has now devised a method for generating such spatially structured electron spins using a structured light with spatially varying polarization profile. The study, published in the journal Physical Review Letters, was done in collaboration with research groups from Chiba University, Tohoku University, and Tsukuba University in Japan.

“In this work, we generated a doughnut-shaped structured light–a vector optical vortex beam with an orbital angular momentum (OAM)– from a basic Gaussian beam using vortex half-wave plate and quarter-wave plate devices. We then used this beam to excite the electron spins confined within a gallium arsenide/aluminum gallium arsenide semiconductor quantum well. These spins, in turn, formed a helical spatial structure in a circle,” explains Dr. Ishihara.

Interestingly, while the beam with an OAM number equal to one produced a helix with two spin periods – spin up and spin down – around the circle, an OAM number of two resulted in a helix with four such alterations. These observations indicated that the spatial polarization structure of the optical vortex, determined by the OAM, was transferred to the electron spins inside the semiconductor. In addition, increasing the OAM number was suggested to enable higher information storage capacity, characterized by higher spin repetition rate around the circle.

Moreover, the researchers utilized the effective magnetic field of the spin-orbit interaction acting on electron spins in the quantum well to simultaneously generate two spin waves with opposite phases in the vertical direction using a single beam. This suggested that various spin states with spatial structures could be produced by exploiting the effective magnetic fields (a characteristic of solids) alongside structured light beams.

With such exciting results, the researchers discuss the future prospects of their work. “The conversion of the spatial polarization structure of light into a spatial structure of spin along with the generation of new spin spatial structures in combination with effective magnetic fields in solids are expected to lead to elemental technologies for higher-order quantum media conversion and information capacity enhancement using spin textures,” says Dr. Ishihara.

It may not be long before such spin-based information storage devices become a reality!***

PASTI: a revolutionary patient monitoring system developed by ITS

A research team from Institut Teknologi Sepuluh Nopember (ITS) has developed a Patient Portable Monitoring System (PPMS) tool into more cutting-edge technology, called Patient Monitoring System with Simplicity Integration (PASTI). With funding from the Institute of Electrical and Electronics Engineers (IEEE) SIGHT 2022 and contributions from four other universities, including Universitas Muhammadiyah Malang, Universitas Dian Nuswantoro, Universitas Bina Nusantara, and Universitas Katolik Atmajaya, the PASTI system represents a major leap forward in patient care. This innovation aims to improve the performance of healthcare professionals and lead to better outcomes for patients.

Dr. Wiwik Anggraeni S.Si., M.Kom., as the developer team explained that the development of PASTI involved six months of work, during which they created a web-based application to simulate the data transaction. It is designed as a modular system that can be easily integrated with existing information systems. This allowed them to demonstrate how PASTI could be used to monitor patients in real-time. PASTI is a prime example of how technology can be harnessed to improve healthcare services and change lives for the better. As this innovative new system continues to evolve, it has the potential to transform the way patients are monitored and treated, making healthcare more accessible and effective than ever before.

The budding potential of chrysanthemum flowers at Taman 1000 Bunga Agrotouris

The linear economic model running in the flower industry has resulted in excessive resource utilization and increased environmental pollution. The circular economy offers a better alternative economic model for realizing sustainable development, focusing on environmental preservation by considering broad social aspects. Floral waste is becoming one of the main problems for agrotourism in the Karo Regency, North Sumatra. The waste from festive events is not being utilized for beneficial purposes, quickly polluting the surrounding areas and contradicting their purpose of beautifying them. As an agricultural waste, the flower is an input source with the potential to be developed to have beneficial values if appropriately processed.

The Karo Regency is famous for its festive events, which generally involve flowers of many kinds; one of them is the chrysanthemum, a colorful flower with eleven unique variants. Karo’s flower industry focuses primarily on its form as fresh flowers. The development of the flower by-products and by-waste is minimal, even though the resulting product can increase the selling value and, therefore, the income of flower farmers. The flower is one of the main displays in the Taman 1000 Bunga (Garden of Thousand Flowers) Agrotourism, managed by a community-based corporation. It provides economic and cultural support to locals. The problem with many festive events is that it only runs some year-round, which poses a threat of loss to garden management, along with hundreds of tons of waste weekly.

A group of researchers from the Faculty of Agriculture, Universitas Sumatera Utara, led by Professor Elisa Julianti, proposed a solution to the problem with the help of industrial partners through a government-supported, highly competitive grant project, Kedaireka. The project is expected to reduce the negative impact of economic activity on the environment, increase added value, reduce price volatility, and increase employment growth for the flower industry. The soon-to-be waste chrysanthemums will be re-purposed through drying machines, turning the flower into chrysanthemum tea. The resulting tea has many restorative benefits, such as curing flu, coughs, digestion problems, asthma, and sinusitis-induced headache, all while regulating blood pressure, helping the detoxification process, and improving vision, based on the research published in Food Chemistry by Lin and Harnly (2010). Thus, the unused flowers can be turned into good herbal tea, averting the discard of massively produced chrysanthemum petals. The garden management has previously attempted to take the proposed actions using a sun-drying method, but this yields a different quality of the resulting herbal tea and production levels. This problem can be solved efficiently using the aforementioned drying machine method, providing a controllable process to acquire the desired condition of produced chrysanthemums’ bioactive parts.

The research team’s efforts, together with industrial partners and the community, would, in turn, provide profits to the community-managed garden, bolstering the production of herbal tea that would benefit many and promote a circular economy. Consequently, the flowers not only provide beauty for the surrounding area but also support local culture and local farmer economy while being sustainable in the process.

AUS collaborate with MBRSC to investigate astronauts’ mental stress

A research team from American University of Sharjah (AUS) investigated the impact of isolation and confined environments on astronauts and provided recommendations on protecting their mental health as part of a collaboration with the Mohammed Bin Rashid Space Centre (MBRSC).

The study involved six primary crew members including Saleh AlAmeri representing the UAE, who were put into a confined environment for 240 days from November 2021 to July 2022 in the SIRIUS facility, during which they experienced simulated long-distance space travel. A backup crew that supported the primary team from the operations center was present, which also included Abdalla AlHammadi from the UAE.

The AUS research team used advanced brain imaging modalities such as electroencephalography, functional near-infrared spectroscopy, alpha amylase biochemical marker and behavioral responses to measure brain electrical activity, blood oxygenation and stress hormone levels. Based on data collected at different stages, the team found an increase in the level of the stress hormone the longer the isolation continued, and a significant decrease in information flow and direction between brain regions, indicating a drop in cognitive abilities due to elevated mental stress.

“The findings of this research will impact future space missions locally and internationally. They will help develop techniques to mitigate stress at its early stages to protect astronauts’ mental health. An additional advantage of this study is applying the findings to our modern-day life in managing workplace environments to reduce the risk of mental stress, leading to an improved quality of life,” said Dr. Hasan Al-Nashash, Professor in Electrical Engineering at AUS.

The study was conducted by Dr. Al-Nashash along with Dr. Fares Al-Shargie, a visiting postdoctoral scholar, and Dr. Usman Tariq, Associate Professor in Electrical Engineering at AUS.

The UAE crew members were trained in the Biomedical Engineering Lab of the Neuroengineering Research Group at AUS by Dr. Al-Shargie and Dr. Al-Nashash on experiments protocol and data collection. The College of Engineering (CEN) labs are furnished with state-of-the-art equipment to conduct the training and experiments. The international crew members were trained online.

“We presented several recommendations, including the use of advanced neuroimaging and artificial intelligence for early detection of mental stress. The research findings motivated us to develop methods for reducing mental stress in confined environments using digital technologies to stimulate human senses to influence the brain in ways that prompt it to control emotions. This work does not only benefit space research but also impacts other social domains including healthcare, safety, education and quality of life,” said Dr. Al-Shargie.

The interdisciplinary nature of research, which combines electrical and biomedical engineering, reflects the quality of education offered to students at the AUS College of Engineering. As one of the most exciting branches of engineering, electrical engineering graduates have many opportunities to shape their future.

AUS offers a highly acclaimed four-year Bachelor of Science in Electrical Engineering (BSEE) degree program that is based on a solid foundation of science and mathematics. AUS is ranked among the top two (tied) in the UAE and top ​300 universities globally for ​electrical ​and electronic ​engineering, according to QS World University Subject Rankings (202​2​). In keeping with the developments in the UAE and wider Middle East, AUS offers a Master of Science in Biomedical Engineering (MSBME) and recently launched a new doctoral program in biosciences and bioengineering (PhD-BSBE) that will be available for students starting Fall 2023.

Training problem solvers in the field of Humanitarian Technology and Inclusive Business

Lingnan University’s new MSc in Humanitarian Technology and Inclusive Business (HTIB) aims to train individuals who can develop the kinds of appropriate and affordable technologies and services required by those at the bottom of the global pyramid. Typically, these technologies are mature, cheap and universally available – for example, LED light, servo motors and various sensors – but even some applications of artificial intelligence (AI) and virtual reality (VR) technology may be appropriate.

Dr Lee cites the example of a 3D VR-enable showroom which helps the growth of inclusive business in a remote area of Bangladesh. By adopting this innovative approach, customers’ satisfaction and confidence are gained by experiencing the spatial requirement and bathroom setting with the toilet they would like to purchase.

“Catering to this customer demographic is not a volunteer job, or a charitable act. Instead, it is a significant business opportunity that has yet to be fully tapped into.,” Professor Albert Ko, HTIB Programme Director, points out.

Aims of the MSc in HITB  

The purpose of the programme is to cultivate professional problem solvers and entrepreneurs who can lead a team in coming up with creative ideas, and subsequently transform them into inclusive business solutions, explains Prof Ko. After graduation, students will be equipped with the fundamentals of inclusive business and innovative design process for humanitarian technology – which will enable students to implement creative solutions effectively, cooperating within interdisciplinary teams of professionals such as engineers and medical workers.

Structure of the programme 

Alongside lectures, tutorials, workshops, and seminars, the programme aims to provide extensive hands-on training through community-based and project-based experiential learning.

The first core course, Inclusive Innovation: Design for a Better World, is one of the highlights of the HTIB programme, notes Dr Jasper van Holsteijn of Lingnan’s School of Graduate Studies. In this course students are taught various innovation skills and how to solve real-world problems

By the end of the programme, students will work on a capstone project – Design Innovation for Addressing Social Challenge – in collaboration with one of Lingnan’s renowned regional and international partner organizations. Students can shape the direction of their project based on their specific interests and future goals to prepare them well for their careers after graduation.

Lingnan: the perfect launchpad for a future in HTIB 

The programme is a perfect expression of the fundamental ethos and guiding principles of Lingnan. The university is always looking for ways to fulfill the promise of its motto of “Education for Service”, so the teaching of problem solving skills to tackle global challenges is a key element within the programme and the university.

In short, the programme aims to equip students with critical problem-solving skills that are essential for creating enterprises that contribute to building an inclusive society. Graduates will have diverse career opportunities, including pursuing postgraduate studies, working with NGOs and development organizations in Hong Kong and overseas, while others will be looking to launch their own companies. Our graduates will be well-equipped to address global challenges and contribute to positive social impact on a local and international scale.
