Bibliometric analysis of augmented reality in chemistry education over the past decade

Numerous studies have delved into the application of augmented reality (AR) in chemistry education, focusing on specific topics, equipment requirements, and advantages. However, there remains a notable dearth of research examining the evolutionary characteristics of AR in this context. This study, employing bibliometric analysis on 66 articles spanning from 2012 to 2022, reveals that research primarily revolves around pedagogical approaches and AR technology development, particularly in kindergarten to 12th grade (K-12) education. Despite the United States exhibiting the highest publication frequency, there is a significant absence of studies addressing emotions, cognition, and physiological changes. Shedding light on these research gaps, this study underscores the need for further exploration into the cognitive, emotional, and physiological aspects of AR integration in chemistry education. Ultimately, the insights gleaned from this study offer valuable guidance for researchers, educators, and practitioners alike, facilitating the advancement and effective application of augmented reality in chemistry education (ARCE).

Influenza and COVID-19 vaccines in pregnancy: investigation on associated factors and HAPA theory

Abstract Background Infections caused by influenza and COVID-19 during pregnancy represent a current public health problem as there are multiple populations at risk of complications: pregnant women, fetus, and future unborn children. The anatomical and physiological remodulation characteristic of pregnancy is responsible for the high pathological burden related to respiratory infections. Co-administration of influenza and COVID-19 vaccines may be beneficial because these two respiratory viruses cocirculate during cold weather. The need to explore pregnant women’s attitudes toward co-administration of influenza and COVID-19 vaccines and to evaluate factors associated with vaccine decision-making led to the conduct of this study. Methods In Palermo, Italy, during the 2021-2022 influenza season, a cross-sectional study was conducted to evaluate pregnant women’s intention to adhere to co-administration of influenza and COVID-19 vaccines. The determinants of vaccination attitudes were investigated through the administration of a questionnaire. The Health Action Process Approach theory (HAPA) was adopted to explore the cognitive behavioral aspects. Results Overall, 120 pregnant women were enrolled; average age 32 years, 98.2% (n = 118) of Italian nationality and 25.2% (n = 30) with obstetric or pathological conditions of pregnancy at risk. Factors significantly associated with attitudes toward co-administration of influenza and COVID-19 vaccines among pregnant women were: high level of education (OR = 13.96; p < 0.001), expectations of a positive outcome (OR = 2.84; p < 0.001) and self-efficacy (OR = 3.1; p < 0.001). Conclusions Vaccines co-administration could represent an advantageous preventive practice to facilitate vaccination logistics and allow full adherence to vaccinations recommended to pregnant women. Effective strategies to promote co-administration of influenza and COVID-19 vaccines could be focused on counselling about the expectation of positive outcomes of vaccine co-administration. Key messages • The need to explore pregnant women’s attitudes toward co-administration of influenza and COVID-19 vaccines and to evaluate determinants of vaccine decision-making led to the conduct of this study. • Vaccines co-administration could represent an advantageous preventive practice to facilitate vaccination logistics and allow full adherence to vaccinations recommended to pregnant women.

Instrumentation of students’ experience through the active content of science: from epistemic contact to idealizations and back again in school classrooms

ABSTRACT The paper presents an in-depth exploration of the process of the instrumentation of experience within the context of teaching and learning in schools. We focus on the role of cultural instruments, such as scientific tools and practices, in mediating human cognition and transforming students´ experience into active scientific content. The study draws on the concepts of dual mediation and the interplay between denotative and expressive aspects of cognition. We aim to (1) characterise the process of instrumentalizing students’ experience into active scientific content within the classroom and (2) propose a theoretically consistent model of instrumentation of experience for micro-level analysis of teaching and learning based on the construct of content transformation. We propose a micro-level model for analyzing the instrumentation of experience in educational settings, highlighting the interaction between the subjective, intersubjective, and objective content modalities, Kvasz's typology of cultural genesis in science and its operationalisation through five epistemic categories (e.g. cognitive penetrability of imagination). The operational grounding of these categories is illustrated through case study examples. This model serves for micro-analysis of content transformations during teaching and learning and thus to contribute to the enhancement of teaching and learning quality through classroom observations and analytical reflection.

A Comparative Analysis of Neurocognitive Function in Community- and Hospital-Based Patients With Schizophrenia.

The study compared differences in various neurocognitive characteristics across treatment modalities among schizophrenia patients recruited in one city between July 2020 and June 2023 who were on regular medication. Of the 151 participants, 113 were included in the analysis. Participants were divided into community-based and hospital-based groups, and their demographics and clinical characteristics, including insight, quality of life, positive and negative symptoms, and personal and social functioning, were examined. In addition, several aspects of cognition were assessed using neurocognitive assessments such as the Trail Making Test (TMT), Stroop test, and Wisconsin Card Sorting Test (WCST). After adjusting for age differences between groups, the final analysis included data from 42 participants in the community-based group and 33 participants in the hospital-based group. Hospital-based group participants completed Stroop-W more rapidly, excelled in Rey-Osterrieth Complex Figure Test recall and recognition, and incurred fewer TMT Part B (TMT-B) and Stroop-C errors. Additionally, they outperformed in WCST total, non-persistent errors, and categories completed. Contrastingly, community-based group participants showed superior outcomes in WCST persistent responses and errors, suggesting specific neurocognitive strengths. We found differences in neurocognitive characteristics between the two groups. These differences were consistent across a range of cognitive domains, including attention, visual discrimination, memory, and executive functioning. Further large-scale study is needed to generalize cognitive characteristics across treatment modalities.

Exploring temporal congruence in motor imagery and movement execution in non-specific chronic low back pain

Chronic non-specific low back pain (NSCLBP) is linked to sensorimotor dysfunctions and altered motor planning, likely due to neuroplastic changes. Motor imagery (MI) and movement execution share neural pathways, but the relationship between imagined and executed movements in NSCLBP patients remains underexplored. This study aimed to assess the temporal congruence between imagined and executed movements in NSCLBP sufferers, with secondary goals of investigating group differences in movement chronometry, psychological well-being, and disability, as well as possible correlations among these factors. Fifty-six participants, including 28 NSCLBP patients and 28 asymptomatic subjects (AS), performed lumbar flexion and Timed Up and Go (TUG) tasks. NSCLBP patients showed significant temporal incongruence in both tasks, executing movements more slowly than imagined, whereas AS displayed incongruence only in the TUG task. NSCLBP patients also took longer to imagine and execute lumbar flexion movements compared to AS, with correlations observed between execution delays, higher disability, and greater fear of movement. The findings highlight a lack of temporal congruence in NSCLBP patients, especially in lumbar flexion, emphasizing the complex relationship between chronic pain, motor ability, and psychological factors. These results suggest that integrated treatment approaches addressing cognitive and emotional aspects are crucial for managing NSCLBP.

Pedagogical Interaction and Student Engagement at Selected University

This quantitative study examined pedagogical interaction and student engagement in a university in Guangdong, China, involving 364 students and 132 teachers. Surveys evaluated pedagogical strategies, including reflective, inquiry-based, and collaborative learning, alongside cognitive, emotional, and behavioral aspects of student engagement. Professional development was measured by the establishment of training systems aimed at enhancing students' capacity to engage in classroom interactions, ensuring that teachers progressively cultivate active participation.The findings show that teachers frequently facilitate teamwork, reflect on their teaching practices, and set clear expectations for group activities. They also promote inquiry-based learning by fostering interactive environments where students exchange ideas and engage in discussions. In problem-based learning settings, teachers guide students through research, data analysis, and presentations. However, Spearman’s rho correlation analysis found no significant relationship between teaching strategies and student engagement, suggesting that changes in one do not necessarily affect the other. This indicates that factors beyond pedagogy, such as student motivation or external influences, may impact engagement. The study highlights the need for more personalized learning approaches and enhanced support systems to encourage participation. And, continuous professional development remains crucial, ensuring educators can create environments that nurture meaningful student engagement, regardless of instructional strategies used.

Bracing urban governance against climate crises: How to integrate high reliability into strategic decision‐making?

AbstractTurning cities socio‐ecologically resilient is one of the pressing challenges in the face of ongoing climate change and accompanying extreme weather events. Despite concentrated efforts within specific urban domains, there exists a necessity for a coordinating mechanism that can concurrently monitor signals of slowly maturing long‐term crises, such as global warming and swiftly intervene to mitigate urgent threats, such as catastrophic floods. This article explores the potential of high reliability principles to inform such a governance mechanism through a novel policy operations room (POR) framework, conceptualizing urban strategic goals as critical infrastructure. We analyze the conditions for integrating elements from top‐down crisis management with bottom‐up participatory scenario exercises and policy simulations in urban governance. Based on pre‐ and post‐POR interviews and meeting transcripts in three Finnish cities we examine the regulative, normative, and cognitive aspects of integration. The analysis indicates that the implementation of a high reliability framework in urban settings can provide valuable support for addressing challenges induced by climate change.

Navigating organizational change through a processual perspective on the transition toward the circular economy: Save The Duck case study

PurposeBy rooting our study in Lewin’s change management theory, we conduct an in-depth case study of a medium-sized fashion firm transitioning toward a CE. Through adopting a multi-level and processual perspective, we offer empirical evidence of the change process and elucidate the drivers and resistance to change factors.Design/methodology/approachWe opt for a single in-depth longitudinal case study of a fashion firm that was born with a sustainable business model and that is in transition toward the CE. We involve multiple informants, and we adopt a processual approach to uncover the drivers and resistance to change factors at different organizational levels (i.e. top and middle management and operational levels).FindingsOur findings enable us to highlight novel key drivers and resistance factors at the organizational level. Regarding the former, we reveal the involvement of top and middle management in the decision-making process and the recruitment of young people. For the resistance factors, we identify adaptation to structural change, reluctant mindset, internal divergence of ideas, and commitment of all organizational levels to the CE.Research limitations/implicationsThe paper presents some limitations. First, our research is based on a single in-depth case study, which, while allowing for rich, detailed exploration, inherently limits the statistical generalizability of our findings. Focusing just on one organization located in a specific industry and geographical context means that our results may not be directly applicable to all organizational settings. Firms belonging to other industries would probably show different patterns of change due to industry-specific drivers and barriers. Also, the institutional and geographical contexts of our case study inevitably influence the cognitive and cultural aspects of the drivers and barriers we identified. Then, our research provides a processual yet not longitudinal view of OCCE, thus not fully capturing the long-term dynamics of the phenomenon.Practical implicationsOur findings underscore the critical role of visionary leadership, particularly stemming from the CEO, in driving CE transition. Leaders should articulate a clear vision for sustainability, foster a culture of experimentation and actively identify opportunities for CE implementation. Moreover, our results suggest that organizational culture plays a fundamental role in supporting CE transition. Creating a dedicated sustainability team to coordinate CE initiatives and counter the internal resistance, fostering the engagement of all organizational levels in CE initiatives, developing training programs to enhance CE knowledge and skills throughout the organization and recruiting young talents are some of the key recommendations we posit to firms aiming to start the process of CE transition.Originality/valueThis paper contributes to the emerging literature on “Organizational Change toward a Circular Economy” (OCCE) by providing a processual analysis of organizational change toward the CE. Through an in-depth exploratory study of a fashion firm in transition toward the CE, we were able to identify drivers and resistance factors and to offer a visual map of our findings to graphically show the change toward the CE and the drivers and resistance to change factors that have thus far been under-investigated from an organizational level (Graessler et al., 2024).

Assessment of the sentiments expressed by traumatic brain injury patients and caregivers: A qualitative study based on in-depth interviews

IntroductionTraumatic Brain Injury (TBI) is a significant public health concern that causes death, disability, and economic burden. Its repercussions affect physical, cognitive, emotional, and behavioral aspects of long-term care needs. Despite improvements in communication among multidisciplinary teams, the management of TBI remains fragmented. ObjectiveThis study aimed to assess patients and caregivers’ experiences through sentiment analysis. Materials and methodsA qualitative cross-sectional study utilized structured topic modeling (STM) to analyze in-depth interview data. The study involved 29 patients with TBI and 27 caregivers in Madrid (Spain), using a survey design. The interviews were conducted, transcribed, and coded independently over 5 months. Sentiments such as anticipation, fear, and emotional concerns were analyzed using three dictionaries. The STM analysis identified four key concepts: desire for independence, potential improvement, need for injury information, and psychological consequences. STM diagnostic graphs were used to determine the number of topics relevant to the evaluation of patient and caregiver concerns. Furthermore, an analysis was conducted across four topics. ResultsThe average age of the patients was 44.2 ± 14.9 years (69 % males). Regarding TBI severity, 59 % of patients had severe TBI, whereas the remaining 41 % had experienced moderate TBI. Among the caregivers, the majority were parents (30 %), partners (24 %), or siblings (24 % each). Among the 51 participants, sentiments were analyzed using three dictionaries. While there were no significant age differences (Z = 0.24, p = 0.815), the STM model was adjusted for significant sex differences (p = 0.017) between patients and relatives. Anticipation and fear prevailed in both groups, highlighting the shared emotional patterns. DiscussionThe analysis of diagnostic graphs indicated the optimal number of topics for evaluation, emphasizing key concerns across different phases of TBI. Patients' main worries shifted from physical symptoms to limitations in daily life and independence. Caregivers highlighted the importance of staff interactions, misinformation challenges, and the need for psychological care. ConclusionKey patient concerns, including dependency on daily activities, limitations in autonomy, and caregiver burden, emphasize crucial areas for enhancement in multidisciplinary treatment. Moreover, the lack of long-term psychological support is a significant barrier to optimal patient and caregiver well-being.

PELATIHAN JURNALISTIK BAGI SISWA SEKOLAH MELALUI PENGGUNAAN MEDIA SOSIAL DI ERA MILENIAL

The dynamics of students in high school currently face various strong and unique challenges related to understanding journalism and the use of social media tools in the millennial era. The use of computers is a real activity of Youth Catholic Community (YCC) which continues to be dynamic. The problems faced by Cenderawasih Catholic High School and Frater High School students in using social media are a lack of good and wise knowledge and understanding, still having an emotional nature or lack of self-control, and not using social media applications constructively. Student learning practices still require serious efforts to increase productivity to be targeted, effective and measurable. The training aims to educate school students in understanding journalistic concepts with 3 (three) main aspects in the use of social media in the millennial era, namely: cognitive (knowledge), affective (attitude), and psychomotor (skills) to produce creative social media content with character constructive. Training methods include pre-training (information questionnaire), training implementation (tutorial, practice, and presentation) and training evaluation (rubric questionnaire). The training has educated students in understanding journalistic concepts with 3 (three) aspects of using social media in the millennial era. The results of the evaluation of 30 students, namely: cognitive aspects of 18 people or 60.00%, affective aspects of 22 people or 73.33%, and psychomotoric aspects of 21 people or 70.00%, so it can be said that in general students have been able to understand the use of social media well good.

Abrupt and spontaneous strategy switches emerge in simple regularised neural networks.

Humans sometimes have an insight that leads to a sudden and drastic performance improvement on the task they are working on. Sudden strategy adaptations are often linked to insights, considered to be a unique aspect of human cognition tied to complex processes such as creativity or meta-cognitive reasoning. Here, we take a learning perspective and ask whether insight-like behaviour can occur in simple artificial neural networks, even when the models only learn to form input-output associations through gradual gradient descent. We compared learning dynamics in humans and regularised neural networks in a perceptual decision task that included a hidden regularity to solve the task more efficiently. Our results show that only some humans discover this regularity, whose behaviour was marked by a sudden and abrupt strategy switch that reflects an aha-moment. Notably, we find that simple neural networks with a gradual learning rule and a constant learning rate closely mimicked behavioural characteristics of human insight-like switches, exhibiting delay of insight, suddenness and selective occurrence in only some networks. Analyses of network architectures and learning dynamics revealed that insight-like behaviour crucially depended on a regularised gating mechanism and noise added to gradient updates, which allowed the networks to accumulate "silent knowledge" that is initially suppressed by regularised gating. This suggests that insight-like behaviour can arise from gradual learning in simple neural networks, where it reflects the combined influences of noise, gating and regularisation. These results have potential implications for more complex systems, such as the brain, and guide the way for future insight research.

Cognitive functions explain discrete parameters of normal walking and dual-task walking, but not postural sway in quiet stance among physically active older people.

Postural control is dependent on the central nervous system's accurate interpretation of sensory information to formulate and execute adequate motor actions. Research has shown that cognitive functions are associated with both postural control and fall risk, but specific associations are not established. The aim of this study was to explore how specific components of everyday postural control tasks are associated with both general and specific cognitive functions. Forty-six community-dwelling older adults reported their age, sex, physical activity level, falls and fall-related concerns. The following cognitive aspects were assessed: global cognition, executive functions, processing speed and intraindividual variability. Postural control was quantified by measuring postural sway in quiet stance, walking at a self-selected pace, and walking while performing a concurrent arithmetical task. Separate orthogonal projections of latent structures models were generated for each postural control outcome using descriptive and cognitive variables as explanatory variables. Longer step length and faster gait speed were related to faster processing speed and less intraindividual variability in the choice reaction test. Moreover, longer step length was also related to less fall-related concerns and less severe fall-related injuries, while faster gait speed was also related to female sex and poorer global cognition. Lower dual-task cost for gait speed was explained by the executive function inhibition and faster processing speed. Postural sway in quiet stance was not explained by cognitive functions. Cognitive functions explained gait speed and step length during normal walking, as well as the decrease of gait speed while performing a concurrent cognitive task. The results suggest that different cognitive processes are important for different postural control aspects. Postural sway in quiet stance, step time and gait variability seem to depend more on physical and automatic processes rather than higher cognitive functions among physically active older people. The relationships between cognitive functions and postural control likely vary depending on the specific tasks and the characteristics of different populations.

Biblical Perspective and Educational Domains in Sex Education: Addressing Gaps in Indonesian Sex Education

In Indonesia, sex education is delivered in public high schools as part of the biology curriculum and under the topic of reproductive health. According to the government’s view, when schools teach students properly about reproductive health, they will have a good understanding of their sexuality. Therefore, there is no need to have any further sexual education outside of the school curriculum. However, about half of the teenagers living in major cities are involved in premarital sex, and the rate of teen abortion and HIV infections is high. This article examined the implementation of sexual education in public high schools in Indonesia using a combination of qualitative and quantitative research. The survey was done on a sample of 416 students from 30 provinces and 66 cities in Indonesia. The finding support a particular approach to sex education that incorporates cognitive, affective, and psychomotor learning aspects of educational taxonomy. We find that it is essential to develop a separate sex education module in addition to the current reproductive health topic taught in biology to encourage students to practice abstinence, rather than just teaching reproductive health.

Effect of Age and Gender on Categorical Perception of Vocal Emotion Under Tonal Language Background.

Categorical perception (CP) manifests in various aspects of human cognition. While there is mounting evidence for CP in facial emotions, CP in vocal emotions remains understudied. The current study attempted to test whether individuals with a tonal language background perceive vocal emotions categorically and to examine how factors such as gender and age influence the plasticity of these perceptual categories. This study examined the identification and discrimination performance of 24 Mandarin-speaking children (14 boys and 10 girls) and 32 adults (16 males and 16 females) when they were presented with three vocal emotion continua. Speech stimuli in each continuum consisted of 11 resynthesized Mandarin disyllabic words. CP phenomena were detected when Mandarin participants perceived vocal emotions. We further found the modulating effect of age and gender in vocal emotion categorization. Our results demonstrate for the first time that a categorical strategy is used by Mandarin speakers when perceiving vocal emotions. Furthermore, our findings reveal that the categorization ability of vocal emotions follows a prolonged course of development and the maturation patterns differ across genders. This study opens a promising line of research for investigating how sensory features are mapped to higher order perception and provides implications for our understanding of clinical populations characterized by altered emotional processing. https://doi.org/10.23641/asha.27204057.

A hybrid self-supervised model predicting life satisfaction in South Korea

ObjectiveLife satisfaction pertains to an individual’s subjective evaluation of their life quality, grounded in their personal criteria. It stands as a crucial cognitive aspect of subjective wellbeing, offering a reliable gauge of a person’s comprehensive wellbeing status. In this research, our objective is to develop a hybrid self-supervised model tailored for predicting individuals’ life satisfaction in South Korea.MethodsWe employed the Busan Metropolitan City Social Survey Data in 2021, a comprehensive dataset compiled by the Big Data Statistics Division of Busan Metropolitan City. After preprocessing, our analysis focused on a total of 32,390 individuals with 51 variables. We developed the self-supervised pre-training TabNet model as a key component of this study. In addition, we integrated the proposed model with the Local Interpretable Model-agnostic Explanation (LIME) technique to enhance the ease and intuitiveness of interpreting local model behavior.ResultsThe performance of our advanced model surpassed conventional tree-based ML models, registering an AUC of 0.7778 for the training set and 0.7757 for the test set. Furthermore, our integrated model simplifies and clarifies the interpretation of local model actions, effectively navigating past the intricate nuances of TabNet’s standard explanatory mechanisms.ConclusionOur proposed model offers a transparent understanding of AI decisions, making it a valuable tool for professionals in the social sciences and psychology, even if they lack expertise in data analytics.

"Such a different type of tiredness": people with brain tumour, their caregivers', and healthcare professionals' qualitative perceptions of cancer-related fatigue.

Cancer-related fatigue (CRF) is one of the most common symptoms reported by people with primary brain tumour (BT). Previous research predominantly examined CRF using quantitative assessments, failing to capture the rich insight garnered from exploring individuals' lived experiences. We addressed this gap by qualitatively exploring people with BTs' experiences of CRF. Semi-structured interviews were conducted with people with BT, their caregivers, and healthcare professionals (HCPs) who care for them. Interviews explored the experience, impact, and management of CRF, including types of support provided by HCPs. Data were analysed using reflexive thematic analysis. Forty participants were interviewed (24 people with BT, 5 caregivers, 11 HCPs). Qualitative analysis identified four themes: pervasiveness of CRF; impacts of CRF; advice and support; and self-management strategies. CRF was described as an almost universal symptom with physical, emotional, and cognitive aspects and profound psychosocial and functional impacts. HCPs reported assessing fatigue and providing management support. Yet, people with BT and caregivers reported CRF assessment and support were rarely received. Consequently, people with BT developed their own management strategies. All participants identified a lack of CRF information resources and interventions specific to people with BT. Our findings provide rich insight into the pervasive, debilitating impact of CRF in people with BT and highlight the lack of BT-specific CRF support and information available. There is a critical need for evidence-based fatigue interventions and information resources tailored to the needs of people with BT.

Mindfulness in Higher Education: Conceptual Perspectives for Self-Leadership and Optimism

Mindfulness can be regarded as a significant factor in transforming the educational landscape in higher education institutions (HEIs) because its integration into educational settings can offer several benefits such as promoting emotion regulation, reducing stress and anxiety, and developing self-control, well-being, and resilience among students and faculty in HEIs. It can foster a more positive learning and work environment in HEIs by enhancing self-leadership and optimism in individuals. Therefore, this study aims to investigate mindfulness in HEIs concerning self-leadership and optimism in the existing literature. Designed as a conceptual exploration of the literature across multiple theoretical perspectives in mindfulness, self-leadership, and optimism in the context of HEIs, this study theoretically examined these concepts in the literature in terms of their definitions and relationships in the existing eligible sources. According to the synthesized results, mindfulness is a transformative factor in HEIs that addresses cognitive, emotional, and social aspects, which promotes comprehensive growth and well-being among students and faculty. Its integration enhances self-leadership skills by improving self-regulation, stress management, and emotional satisfaction among both students and faculty. Furthermore, mindfulness fosters optimism in individuals and contributes to a positive academic environment characterized by resilience and enhanced performance. Despite its benefits, the careful consideration of ethical, cultural, and developmental factors is essential in implementing mindfulness practices to ensure their effectiveness. With the support of policymakers and educational leaders, mindfulness can significantly enhance the quality of HEIs and create a thriving academic community.

Teacher Support as Predictor of Student Engagement in College English Course in Selected HEIS in China

This study adopted quantitative method to investigate the predictive role of teacher support in student engagement in College English courses at selected universities in China. The study population consisted a sample size of 379 students and 124 teachers, and assessed the level of teacher support in terms of emotional, academic, and instrumental support, as well as behavioral, emotional, and cognitive aspects of student engagement. Through Mann-Whitney U test and multiple linear regression analysis, the study revealed the teacher-student differences in perceptions of teacher support and student engagement and also the predictive role of teacher support on student engagement, with implications for enhancing educational practices. The study revealed that both teachers and students rated teacher support positively in terms of emotional, academic, and instrumental support, with slight differences. There was no significant difference between teacher and student assessments of overall teacher support, though students rated emotional support higher. However, a significant difference was found in the assessment of student engagement, where students rated their engagement—especially emotional engagement—higher than teachers. Also, it was found that academic and instrumental support were significant predictors of student engagement, with academic support having the strongest impact. Based on these findings, a teacher support program is proposed to enhance student engagement in College English classes. The findings of this study have implications for teacher professional development in higher education. It highlights the importance of teacher support, especially academic and instrumental support, teachers towards boosting student engagement in College English class. Schools should prioritize ongoing training that helps teachers better understand and meet students’ academic and emotional needs, while also improving their ability to provide practical instrumental support. Professional development programs that strengthen and improve these areas can enhance teaching effectiveness, reduce discrepancies in student engagement perceptions, and ultimately improve student academic performance in College English classes in China.

Microbiological bases of obsessive‑compulsive disorder - the role of viruses, bacteria, and parasites in the onset and progression of OCD.

Obsessive‑compulsive disorder (OCD) is a current topic of discussion nowadays. OCD presents a variety of different etiologies including environmental, viral, cognitive, or genetic aspects. In this article, we focused on the possible correlation between various infectious diseases as well as generally the relationship between viruses, bacteria, and parasites, and an increased OCD risk. In this narrative review, we analyzed different types of articles found on PubMed, Google Scholar, and Scopus, as well as the articles of the National Institute of Mental Health. Searching criteria included articles from 1991 till the end of November, research involving human and animal patients (including monkeys and rats), and research published in English. Research showed a relationship between Herpes simplex virus, Rubella virus, Human immunodeficiency virus, Borna disease virus, Mycoplasma pneumoniae, Toxoplasma gondii, streptococcal infections, as well as gut microbiota and increased OCD risk. The possible mechanisms of this relation include neuroinflammation, brain tissue damage, autoimmune processes, and impairments in neurotransmitter levels. Infections caused by Varicella zoster virus, Measles virus, Mumps virus, Epstein‑Barr virus, Cytomegalovirus, or Borrelia Burgdorferi may also contribute to the increased risk of OCD. Reports showed an increased frequency of OCD occurrence in a group of infected people compared to a healthy group. However, there is no evidence of the influence of Influenza virus, Coxsackie virus, Poliovirus, Parvovirus B19, Enterovirus 71, West Nile virus, Treponema Pallidum, or Toxocara infections on the OCD risk. There is a significant relationship between various infectious diseases and an increased OCD risk. However, further studies are crucial to discover the exact pathomechanisms of these correlations and the potential influence of other pathogens on the onset of OCD.
