Oral expression is a fundamental communication skill that involves interaction, bidirectionality, and negotiation of meanings within a shared context . It plays a crucial role in human society by allowing the transmission of cultural information, customs, and behaviors through stories and oral traditions . Effective oral expression is essential for language development, as seen in studies focusing on programs aimed at improving oral skills in languages like English and French, demonstrating significant improvements in pronunciation, grammar, lexical precision, interaction, and communicative comprehension . Through scenarios like role-playing, simulations, debates, and metacognitive strategies, oral expression can be enhanced in educational settings, leading to increased proficiency levels and improved performance in language activities . In essence, oral expression is a dynamic process that underpins effective communication and language acquisition.
Oral communication refers to the process of expressing information verbally, either through spoken words or nonverbal cues. It plays a vital role in various aspects of life, including education, professional settings, and language learning. Effective oral communication involves clear articulation, confidence, and the ability to convey messages accurately. In the realm of advertising, transforming text information into oral expression can enhance message comprehension, especially when incorporating rhythmic elements or fixed modes. Both written and oral communication are essential forms of interaction, with oral communication being particularly crucial for language learners to develop proficiency in expressing themselves confidently and overcoming stage fright. Overall, oral communication is a fundamental skill that enables individuals to convey ideas, emotions, and information effectively through spoken language.
Dramatic reading or oral interpretation involves the expressive vocalization of text to bring characters and narratives to life. This approach enhances various skills like prosody, fluency, and comprehension, particularly beneficial for students with dyslexia. Through readers' theater, students engage in experiential learning, exploring complex levels of thinking and creativity while performing literary works. By incorporating gestures and group dynamics, students can delve deeper into the meaning of words and senses, making reading a performative art. Authors emphasize the significance of sound in understanding their work, highlighting the oral nature of language as a bridge between author and reader. Overall, dramatic reading serves as a powerful tool for literary engagement, comprehension, and creative expression across various educational backgrounds and age groups.
Oral tradition and folklore shape the ways in which people understand the world by serving as a medium for cultural renaissance and education of values, morals, and aesthetics . Folklore also played a role in nation building and perpetuated violence against minority groups through negative stereotypes in folktales . Traditional tales, like genes and languages, are products of descent with modification and are entangled with other patterns of ancestry, providing insights into the cultural success and stability of these stories . Oral traditions form the basis for establishing roots of life within a community and conceptualizing relationships with others, emphasizing the importance of idiom, metaphor, and simile in tracing origins and conceptions of life . The study of oral tradition and cultural expression in non-literate tribes helps understand and interpret their worldview, highlighting the need for interdisciplinary methods to accurately capture their cultural manifestations .
Oral traditions are cultural practices that are passed down from one generation to another through spoken words, songs, folktales, and other forms of oral communication. They serve as a means for communities to preserve their history, knowledge, and values. Oral traditions are found in various cultures around the world, such as the Simalungun community in Indonesia , local people establishing their roots and authority within a society , the diverse culture of Tamil Nadu in India , the Balinese-Hindu community in Lombok , and African dramaturgy . These traditions play a significant role in shaping identity, transmitting cultural heritage, and communicating important messages. They are a reflection of the customs, beliefs, and practices of a society, providing insights into its daily life and worldview.
Art in primary education plays a crucial role in fostering creativity, cognitive development, and overall well-being in children. Integrating art into school curricula from primary to higher education levels is essential for enhancing students' academic performance, self-esteem, and artistic sensibilities . Research indicates that visual, auditory, and tactile stimuli in arts education significantly contribute to the development of creative thinking in children, leading to improved creative abilities . Additionally, immersive methods in art education help students think creatively, become active citizens, and enhance their communication skills, ultimately encouraging critical thinking and problem-solving through visual expression . Furthermore, art lessons in preschool and primary schools are fundamental for forming well-rounded personalities, nurturing creativity, and developing abstract thinking and artistic taste in children, which are vital for their future growth and success .
Social media has a significant impact on college students' time management, affecting their academic pursuits and overall well-being. Research studies have shown that students spend excessive amounts of time on social media platforms, leading to a decrease in commitment to academic activities, inefficient time management abilities, and mood swings . Additionally, the fear of missing out on social media content drives students to engage in multitasking, which further hampers their academic performance . Conversely, some studies suggest that social media can positively influence students' academic achievements by enhancing their focus and investment in studies . However, the excessive use of social media can also consume a significant portion of students' free time, diverting their attention from more productive activities and impacting their overall time management skills .
Stylistics plays a crucial role in creating an immersive and engaging narrative experience by utilizing various linguistic and narratological features to draw readers or viewers into the storyworld . Through stylistic analysis, critical language awareness can be developed, enabling readers to assess ideologies transmitted in discourse and fostering critical thinking by helping them understand the interpretative nature of text meanings . Additionally, in the realm of advertising, narratives that are more relevant and vivid can enhance advertising persuasiveness by increasing emotional engagement and decreasing skepticism, ultimately leading to more positive attitudes towards the ad and brand . Moreover, in cinematic virtual reality, the choice of point of view (POV) significantly impacts narrative engagement, with the first-person perspective (1-PP) potentially offering a more immersive experience than the external perspective (EP) if effectively utilized .
Work from home, also known as telework or telecommuting, has a long history that dates back to the 1970s in the United States . However, the concept of working from home has evolved significantly over time, with the post-industrial era witnessing a notable trend towards the home becoming a central hub for work activities, blurring the traditional boundaries between work and home environments . The rise of teleworking, enabled by advancements in information and communication technologies, has been a key driver in the increasing prevalence of remote work arrangements, with a substantial portion of the workforce, around 11%, reported to be working mainly from home as of 2005 . This shift towards remote work has been further accelerated by external factors such as the COVID-19 pandemic, which has reshaped traditional work settings and highlighted the importance of flexible work arrangements that include working from home .
Mental imagery plays a crucial role in shaping human-robot interaction by influencing various aspects of the interaction process. Research suggests that humans form mental images of 3D scenes to support counterfactual imagination, planning, and motor control, which can aid in manipulation tasks and action planning . Additionally, mental models provide a formal mechanism for achieving fluent and effective teamwork during human-robot interaction, enabling awareness between teammates and coordinated action . Imagined contact with a robot, similar to real interactions, can improve human-robot interaction quality and elicit more positive behaviors towards the robot, showcasing the impact of mental simulations on interaction perception and behavior . Furthermore, human mental models of robot agents can affect decision-making and subjective assessment during interactions, with participants' action choices revealing information about their mental models of virtual agents, highlighting the potential for improving human-robot interactions through inferred human models of robot agents .
Last summer Nonie Lesaux , a professor at the Harvard Graduate School of Education who leads a research program that seeks to improve literacy outcomes for children and youth, was approached with a problem. The New York State Education Department (NYSED) needed to help the 600-plus school districts that the state agency serves better understand what scientific research had to say about how children learn strong reading and writing skills. Their query came at a time when powerful public advocacy for bringing the science of reading to classrooms, which had been steadily gaining momentum, had reached a fever pitch.
Over roughly the past decade, 38 states and the District of Columbia have passed laws or introduced policies that aim to bring literacy instruction in line with decades of interdisciplinary research on the science of reading. In New York, in fact, Governor Kathy Hochul introduced a plan earlier this year to have schools in the state adopt science-based methods to improve reading instruction by September 2025.
When they approached her last summer, administrators at NYSED told Lesaux that many school district leaders and educators across the state felt “angst, confusion, and worry about the science of reading.” They weren’t sure what the term meant exactly — they had lots of questions, and they needed clarity and resources, she says, to help them “cut through a lot of noise,” including some misconceptions.
So Lesaux produced a series of seven briefs to help the educators better understand the research, as well as the work that is needed. The briefs explore key ideas and myths about the science of reading, and leadership strategies for those in New York’s preK–12 systems who are working to improve literacy and provide professional learning supports.
Lesaux recently discussed the briefs, as well as how they have been received.
You worked with NYSED on a series of literacy briefs back in 2017. How did you build on that previous work with this new set of briefs?
Literacy is still the multifaceted, complex construct that it always has been, and the demands on the learner and the citizen today, in this global knowledge-based economy, are significant. You have to develop literacy skills to a level that is much higher than might have been necessary even 25 years ago, for entry into the workforce and for a good wage and income and lifestyle — that hasn't changed. … There is some overlap [in the briefs] because the knowledge base didn't change much. I think what changed, which was super important for the field, is the public became much clearer that there are effective and ineffective ways to teach early word reading.
In your first brief, you say that the science of reading reflects more than 50 years of research across multiple disciplines about how children successfully learn to read and write. If there is so much research and evidence, why has there been so much confusion about effective literacy instruction?
I think what has created some of the confusion is that there are a couple curricula and approaches that took hold at large scale — this kind of “leveled reader” approach, “balanced literacy” — and the field took that up and the research was not there. In fact, it's deleterious for some kids because it's not the right approach. It's true that phonics instruction should be very explicit and direct, and that is not the same as teaching language and comprehension. And we need the language and comprehension teaching, but we can't confuse the two. And I think for far too long there was sort of this text-based approach to teaching phonics that wasn't actually the explicit direct instruction that a very significant number of children both need and respond so well to. But I think the danger is that we then swing the pendulum and pit the two ideas against each other, ideologically, and create this thing called “the reading wars,” when in fact we know we need a strong plan for phonics, and we need a strong plan for language and comprehension. It sounds so basic, and yet the politics and some of the ideologies of what it feels like to educate in developmentally appropriate ways got in the way of all of this. You know, rote explicit phonics instruction only needs to be about 20 minutes a day, but if you overdo it and it becomes synonymous with your reading instruction, you don't have a very engaging academic environment. When you do it really well and in the short burst that every first and second grader needs, it becomes very reinforcing and exciting because kids see their growth.
In one of your briefs, you set out to debunk common myths about the science of reading and you point out that learning to read and reading to learn should not be two distinct stages. You say effective teaching aims to teach all skills simultaneously from the earliest years?
Yeah, we need to stop pitting the two and we need to do both really well…. [and be] honest about the fact that there are lots of kids who don't have a vulnerability in the phonics area and don’t need more than the standard foundational instruction in this area, but who have very underdeveloped vocabulary and comprehension skills, you know, à la achievement opportunity gaps, and need a lot of content building knowledge. So, if we turn around and only do structured rote phonics programs, ad nauseum, they’re no better off for the long run.
What you mentioned about building up students’ background knowledge, to assist with reading comprehension, makes me think about the work of HGSE’s Jimmy Kim , correct?
Definitely. Jimmy’s portfolio of research has shed light on the effective strategies and the complexity of building up knowledge and comprehension skills. The same is true for Meredith Rowe's vocabulary work . There are others at HGSE, like Nadine Gaab with her [dyslexia] screening work , whose research is equally important. We’re all in the same fight together, contributing in specific ways for the same outcomes, but we're all looking at different pieces.
Regardless of which pieces we’re each focused on, some of the feedback that I get repeatedly [from school districts] is that it's so helpful that we step back and look at the policy and practice landscape and look at what the research really tells us about where we are, and then craft guidance in the form of resources and tools.

Searching in a comprehensive, systematic way requires authors to execute analogous searches in multiple databases, but not all databases accept the same search syntax, and most databases use different vocabulary for subject headings (or don't use subject headings at all).
As such, once a search strategy has been developed in one database, it is necessary to 'translate' it into a form that will work in a different database.
Here is the same search criteria (diabetes + self management), executed with database-specific search queries for three different databases.
(diabetes OR diabetic* OR (MH "Diabetes Mellitus+")) AND (“self management” OR “self care” OR “self monitoring” OR “self regulation” OR (MH "Self-Management") OR (MH "Self Care+"))

UKNow is highlighting the University of Kentucky’s 2024-25 University Research Professors. Established by the Board of Trustees in 1976, the professorship program recognizes excellence across the full spectrum of research at UK and is sponsored by the Office of the Vice President for Research.
LEXINGTON, Ky. (June 27, 2024) — Octavio A. Gonzalez, D.D.S., Ph.D., a professor in the Center for Oral Health Research and Division of Periodontology in the UK College of Dentistry with a secondary appointment in the Department of Microbiology, Immunology and Molecular Genetics in the College of Medicine , has been honored as a 2024-25 University Research Professor.
Gonzalez joined UK in 2010. His research focuses on identifying cellular and molecular mechanisms through which oral pathogenic bacteria and aging affect the gum’s tissue responses. These responses can lead to oral inflammation and loss of the tissues that support the teeth, like gum disease, also known as periodontitis.
His research has been continuously funded by the National Institute of Dental and Craniofacial Research (NIDCR) since 2004.
Gonzalez spoke with UKNow about his latest honor as a University Research Professor in this Q&A.
UKNow: What does it mean to you to be recognized as a University Research Professor?
Gonzalez: It represents a tremendous honor for me. Being recognized as a University Research Professor reminds me that the teamwork in our lab every day is serving to strengthen research as one of the fundamental pillars of our university. It’s also having a positive impact in our colleagues, students and the overall UK community.
UKNow: How will the professorships program advance your research?
Gonzalez: The professorships program will advance our research by significantly raising the bar of motivation to continue working in oral health research and supporting the development of new experimental work for future grant proposals. It will also help us to recruit and work with new students showing interest in our research.
UKNow: How does your research address challenges facing Kentucky?
Gonzalez: Periodontitis affects about 50% of the U.S. and Kentucky adult population. This number increases with aging, affecting 65% of people over the age of 65. Importantly, periodontitis not only has local effects — destruction of gum and bone tissues leading to tooth loss — but it has also systemic impact as risk factor for diseases such as diabetes, cardiovascular diseases, rheumatoid arthritis and Alzheimer’s disease. All these are chronic diseases whose prevalence increases with aging and are affecting a high number of Kentuckians. Therefore, the identification of new potential preventive and therapeutic possibilities to control periodontitis more efficiently will contribute to improving oral health as well as systemic health of Kentuckians.
UKNow: What impact will your research have on Kentucky?
Gonzalez: Our research will provide the foundation for the development of new preventive and therapeutic alternatives to control periodontitis more efficiently in adult and elderly patients in Kentucky and the U.S. Such alternatives will be based on specific or personalized host modulation of inflammation and/or specific control of oral pathogenic bacteria as adjunctive therapies to currently approved mechanical cleaning or debridement treatments.
In addition, our research will have a positive impact in the education of future generations of dentists and scientists in Kentucky who would take forward the important task of improving oral health through research.
About the University Research Professors Each year, the University of Kentucky Board of Trustees approves a cohort of faculty as University Research Professors . The distinction recognizes excellence in work that addresses scientific, social, cultural and economic challenges in Kentucky and the world.
College leadership developed criteria for excellence within their area of expertise and then nominated faculty who excelled at these criteria. Each University Research Professor receives a one-year award of $10,000 and participates in other events planned around the program.

Scientific expeditions into the oral cavity reveal how microbes shape health .
To microbes, our mouth is an entire world unto itself — the gums, tongue, and teeth are habitats as distinct as the earth’s jungles, deserts, and Arctic. Bacteria, fungi, viruses, and other microorganisms that live in and on us — collectively known as our microbiome, or microbiota — inhabit nooks and crannies throughout the oral cavity, like animals and insects finding their homes in trees, sand dunes, and snow.
Some of these microbes cause oral diseases such as tooth decay, gum disease, lesions, and oral cancer, or are associated to systemic conditions like diabetes, dementia, and heart disease. An unhealthy microbiome can even drive formation of harmful viruses in the oral cavity. Yet most microbes promote health. They crowd out disease-causing germs to protect their turf, train the immune system to recognize harmful bugs, and spew tiny molecules that fight foes. Knowing which organisms are where, how they interact with each other, and why they behave the way they do is crucial for maintaining our oral and overall health and well-being.
For over 65 years, NIDCR-supported scientists have explored the oral cavity to understand this microbial world. In past decades, scientists at the institute demonstrated that the bacteria that cause tooth decay are transmissible and infectious and that certain bacteria cause gum disease, pushing the relationships between microbes and health into the spotlight. These early studies were the first to establish the concept of the microbiome, and they laid the groundwork for later research on the microbiome in other parts of the body. Multiple NIDCR-supported projects, including the Human Microbiome Project and the Human Oral Microbiome Database, enabled scientists to take detailed censuses of these tiny players, producing comprehensive maps of microbial communities across the body.
Today, building on decades of knowledge, oral microbiome research continues to flourish. Some NIDCR-supported scientists are investigating how microbes populate the oral landscape and, like miniscule city planners, build tiny towns. Other researchers are studying molecules that nourish health-promoting microbes and suppress disease-driving ones to identify prebiotics that could improve oral health. Scientists have studied relationships between the oral microbiome and multiple systemic diseases. Still others are exploring oral microbial “dark matter,” the microbes that scientists know exist, based on genomic studies, but cannot be grown and studied in petri dishes. These mysterious microorganisms are also sometimes called “uncultivables.”
“Because of the mouth’s accessibility, it was the first and remains one of the most-studied body sites in human microbiome research,” said NIDCR Deputy Director Jennifer Webster-Cyriaque, D.D.S., Ph.D. “The oral microbiome has provided insights into microbial ecology and host-immune responses and disease within the mouth and throughout the body. It is a crucial component of both oral and systemic health.”
Fantastic Microbes and Where to Find Them
While the microbial communities in the mouth are exposed to the same temperatures, saliva, and immune factors, they’re not just random groupings of cells and organisms. By growing bacteria in the lab and sequencing their DNA, scientists have discovered that the microbial composition of the cheek linings, roof of the mouth, and even above and below the gumline are distinct. However, these methods only reveal the general region where microbes live. It’s like knowing a zip code but not an address.
To pinpoint the exact locations of the bacteria in these microbial communities, senior scientist Jessica Mark Welch, Ph.D., and senior investigator Gary Borisy, Ph.D., of the ADA Forsyth Institute, designed a new imaging method that color-labels eight to 10 groups of bacteria at once. Peering into scrapings from dental plaque and tongues of healthy participants with this new method, the scientists were able to visualize microbial towns in rainbow hues.
In the dental plaque samples, the town center was composed of a magenta-stained bacterial species called Corynebacterium , with long filaments that anchor to teeth. Bordering these filaments, making up the outskirts of the town, were tiny green spheres of oxygen- and sugar-consuming Streptococcus . Orange Aggregatibacter often neighbored Streptococcus , feeding off the acidic molecules they produce. Below this initial layer of microbes resided carbon-dioxide-loving, oxygen-averse bacteria like Capnocytophaga and Fusobacterium , stained in red and yellow, respectively.
“These microbial structures function in much the same way that an oak tree provides a habitat for birds, squirrels, and other creatures,” said Dr. Mark Welch. “We haven’t seen any microbial organization as complex as what we see in the human mouth.”
The NIDCR-supported study, published in 2016, offered a new perspective on the oral microbiome, revealing functions and microbial relationships that couldn’t be gleaned from genomics alone. Drs. Mark Welch and Borisy continue to map other oral sites using imaging and DNA sequencing. They believe learning where bacteria live and what they do can reveal strategies to encourage growth of health-promoting bacteria in the mouth.
“This world of bacteria is just so amazing — they build bacterial high rises and microbial apartment buildings in your mouth,” said Dr. Mark Welch. “It’s been right there forever, and yet we’re only just now seeing it.”
Friend or Foe?
Residents of these oral microbial towns are deeply interconnected. In some cases, they work together to drive disease. In other cases, they compete for turf and resources. These microbial interplays can sway our health in one direction or the other.

A recent NIDCR-supported study found that the bacterium Streptococcus mutans , a major driver of tooth decay, has a partner in crime — Selenomonas sputigena . The team found that S. sputigena forms a honeycomb-like structure that encases S. mutans to increase and concentrate the production of tooth-damaging acid, which boosted tooth decay in mice. Breaking up this bacterial duo, which is linked to tooth decay in children, could be a caries prevention strategy. The study was led by Kimon Divaris, D.D.S., Ph.D., and Di Wu, Ph.D., at the University of North Carolina at Chapel Hill, and Hyun (Michel) Koo, D.D.S., Ph.D., from the University of Pennsylvania.
S. mutans can even form cross-kingdom partnerships to promote tooth decay. Dr. Koo and collaborators recently discovered that S. mutans can hitch a piggyback ride on oral fungi. In lab experiments, the bacteria and fungi formed a superorganism that “walked” and “lunged” across tooth-like surfaces by using the fungi’s fiber-like hyphae as legs. These movements allow the microbes to spread faster and farther than either organism alone, shedding light on the interplay between microbes and disease.
Recent studies from Jessica Scoffield, Ph.D., of the University of Alabama at Birmingham showed that a friendly bacterium found in healthy microbiomes called Streptococcus parasanguinis is a gatekeeper of oral health. This bacterium can help turn nitrite, a byproduct of dietary nitrate abundant in leafy greens like spinach and lettuce, into antimicrobial molecules. In 2019, Dr. Scoffield’s team showed that rats that had been colonized with S. parasanguinis and drank nitrite-laced water had less tooth decay after being infected with disease-driving S. mutans than those that did not receive nitrite.
“The presence of nitrite or nitrate reduces the ability of tooth-decay-causing pathogens to eat sugar,” said Dr. Scoffield. “The findings also highlight the importance of a healthy diet — eat your leafy green vegetables.”
More recently, her team found that nitrite aids S. parasanguinis in suppressing the growth of oral pathogens, assuring the healthy bacterium’s dominance. Nitrite triggers the bacterium to produce unique metabolic signals that kill pathogens while protecting itself, a previously unknown phenomenon.
The NIDCR-supported study suggests that nitrite might be useful as a prebiotic to foster oral health. It also opens a door to new research on how metabolic signals alter the structure and function of oral microbial communities, which may lead to potential therapeutics.
Oral Microbial “Dark Matter”
While the mouth is arguably the most well-studied microbial habitat in our body, out of the 774 known oral bacterial species, one-third are considered microbial “dark matter.” Scientists know these microbes exist because they can detect their DNA, but they struggle to grow them in labs. For this reason, these elusive bacteria are also sometimes called “uncultivables.”
Many dark matter species belong to a group of ultra-tiny bacteria called candidate phyla radiation (CPR). The family was first described in 1981 and is found almost everywhere: in soil, seawater, hot springs, termite guts, and humans. But no one had successfully isolated them, and they had remained elusive until 2015, when senior scientist Xuesong He, D.D.S., Ph.D., of the ADA Forsyth Institute, first grew a CPR bacterium called Nanosynbacter lyticus strain TM7x (TM7x for short) in the lab.
Sphere-shaped TM7x bacteria (light gray) are physically bound to the rod-like S. odontolytica . The two microbes live a symbiotic lifestyle. | Xuesong He, ADA Forsyth Institute
As it turns out, it was impossible to isolate and grow TM7x bacteria on their own because these nano-sized spherical cells are physically bound to their rod-shaped host, Schaalia odontolytica .
“TM7x is missing a lot of genes that allow it to exist as a free-living bacterium,” said Dr. He. “For example, they cannot produce many of the amino acids that are building blocks for life. They must suck up nutrients from the host, and that explains their reliance.”
Dr. He’s team dove into studying the relationship between TM7x and S. odontolytica . In an NIDCR-supported study, they found that although TM7x is parasitic, which hampers the growth of its host and can even kill the host, there are benefits to the relationship. TM7x protects the host from predators called phages that hunt and kill bacteria. It does this by influencing gene expression in the host, causing changes to the structure of molecules on the host’s surface, which helps prevent phages from attaching to and destroying the bacterium.
Previous research has revealed links among TM7x, gum disease, and other inflammatory diseases. However, Dr. He and his long-time collaborator Batbileg Bor, Ph.D., at ADA Forsyth Institute say the disease connection is complex. In their lab experiments, introducing the host, S. odontolytica , by itself into mice triggered gum inflammation. But colonizing mice with S. odontolytica along with TM7x caused inflammation to subside, pointing to TM7x’s potential as a health-protective organism.
“All the knowledge we’ve gained can be a roadmap to understand other uncultivable bugs,” Dr. He said. “In addition, it is estimated that over 25% of Earth's microbial species have a symbiotic lifestyle similar to TM7x.”
What the Future Holds
Today, multiple NIDCR-supported projects continue to build on the foundation of microbial knowledge gained to date, aiming to turn lab discoveries into better health and well-being. One group of researchers is identifying health-promoting oral bacteria to develop probiotics to maintain oral health. Others are exploring an innovative dental filling that can fight disease-causing bacteria through small pulses of electricity. Many more are characterizing the microbial communities that contribute to certain diseases, and more importantly, how to restore balance to the oral microbiome and shift disease to health.
“As we unravel the intricate relationships among microbes, disease, and health, we open up opportunities for innovative treatments and preventative strategies,” said Tamara McNealy, Ph.D., Director of NIDCR’s Oral Microbiota and Bacterial Disease Program. “Understanding the oral microbiome is important not just for the teeth and gums; it’s about the health of the entire body.”
