Social representations of young people about people with disabilities and disabilities in an inclusive educational environment: the experience of cross-cultural research

Relevance. Interest in the study of social representations arose due to the development of inclusion in all spheres of life. This fact has an impact on the specifics of training Russian and foreign students in this field in a medical university, the development of their inclusive competence. The study of cross-cultural features of social representations of persons with disabilities and the disabled, the identification of universal and specific phenomena in respondents will contribute to understanding social and psychological phenomena at the individual level that determine social attitudes and behavior of individuals in an inclusive modern society, taking into account its sociocultural characteristics.The purpose of the study is to study the cross-cultural characteristics of social perceptions of people with disabilities and people with disabilities among Russian and foreign students.Objectives: to analyze the content characteristics and approaches to the study of social representations; to develop programs of empirical research; to describe the results of the study; to formulate conclusions.Methodology. This study is based on the provisions of the theory of social constructionism (P. Berger, T. Lukman; J.Douglas); E. Durkheim's concepts of collective representations; theories of social representations (S. Moscovici, D. Jodelet, etc.). Research methods: theoretical analysis of literature, research interview, method of verbal associations, testing, content analysis.Results. Both similar and specific phenomena in social representations of people with disabilities and people with disabilities in the samples of Russian and foreign students were revealed. Similar is the presence of tolerant attitudes towards people with disabilities and people with disabilities in both samples. The differences relate to the social level of social perceptions, as well as the characteristics of social distance in relation to respondents to this category of citizens.Conclusions. Along with a tolerant attitude towards people with disabilities and people with disabilities, respondents have insufficient professional awareness of this category of citizens, experience difficulties in interacting with them at the level of joint activities and professional relationships, which requires the development of additional programs and practices in the context of social, educational and volunteer activities to develop inclusive competence of students.

Towards Strength–Ductility Synergy in Cold Spray for Manufacturing and Repair Application: A Review

Cold spray is a solid-state additive manufacturing technology and has significant potential in component fabrication and structural repair. However, the unfavourable strength–ductility synergy in cold spray due to the high work hardening, porosity and insufficient bonding strength makes it an obstacle for real application. In recent years, several methods have been proposed to improve the quality of the cold-sprayed deposits, and to achieve a balance between strength and ductility. According to the mechanism of how these methods work to enhance metallurgical bonding, decrease porosity and reduce dislocation densities, they can be divided into four groups: (i) thermal methods, (ii) mechanical methods, (iii) thermal–mechanical methods and (iv) optimisation of microstructure morphology. A comprehensive review of the strengthening mechanism, microstructure and mechanical properties of cold-sprayed deposits by these methods is conducted. The challenges towards strength–ductility synergy of cold-sprayed deposits are summarised. The possible research directions based on authors’ research experience are also proposed. This review article aims to help researchers and engineers understand the strengths and weaknesses of existing methods and provide pointers to develop new technologies that are easily adopted to improve the strength–ductility synergy of cold-sprayed deposits for real application.

Youth service co-operatives: An experimentation in empowerment.

In this short piece, I reflect on some research I conducted with colleagues on young people, Youth Service Co-operatives (YSCs), and co-operative education which was originally published in the RECMA-Revue internationale de l’économie sociale. The research focused on the capacity of YSCs to foster young people’s empowerment. Here I share some of the findings of the study, using Ninacs’ rope metaphor, then discuss learning in youth co-operatives, and conclude with some reflections on the research experience and wider implications of the findings.

The Low-Income and Middle-Income Countries' Perspective on Global Neurosurgery Collaborations.

Access to neurosurgical care is limited in low-income and middle-income countries (LMICs) and in marginalized communities in high-income countries (HICs). International partnerships represent one possible means of addressing this issue. Insights from surgeons in HICs have been explored, but data from LMICs' counterparts are scarce. We aimed to study the perspectives of neurosurgeons and trainees from LMICs regarding global neurosurgery (GN) collaborations and interests, motivators, and challenges in participating. An online survey was conducted targeting neurosurgeons and trainees from LMICs. The survey explored demographics, previous experiences, ongoing activities, interests, and barriers related to GN activities. Data were collected between July 2022 and December 2022 and analyzed. Responses involved 436 individuals. The most represented region (25%) was sub-Saharan Africa, and most respondents were male (87.8%) aged 35-49 years. Interest in GN was high, with 91% after its developments. Most respondents (96.1%) expressed interest in training, professional, or research experience in HICs, but only 18.1% could cover the expenses. A majority (73.2%) strongly agreed to return to their home country for work after HIC training. Ongoing HIC-LMIC partnerships were reported by 27.8% of respondents. Clinical exposure emerged as the most relevant motivating factor (87%), while financial concerns, lack of opportunities, and lack of program support were identified as important barriers. Funding and dedicated time were highlighted as the most crucial facilitators. Understanding the perspectives of neurosurgeons and trainees from LMICs is essential to expanding HICs-LMICs collaborations and improving access to neurosurgical care worldwide. Financial support and targeted interventions are needed to address barriers and promote equitable partnerships in GN.

Forschen ist Silber, Publizieren ist Gold. Publikationsverhalten im Wissenschaftsbetrieb

Abstract As the current higher education system also ranks the performance of individual researchers through quantitative methods, i.e. according to scientific productivity and the citation of publications in relevant journals, the article critically examines the effects of common evaluation procedures of scientific practice, which have led to a change in publication practice. Since publications abroad and in English-language journals are considered proof of internationally competitive science and academic education, the accumulation of credit points from such types of publication is gaining in importance to fulfill the formal requirements for a career at universities. In this context, not only the publication behavior of young scientists after their doctorate is considered, but also the publication practice of experienced researchers.

Computational applications for the discovery of novel antiperovskites and chalcogenide perovskites: a review.

Novel perovskites pertain to newly discovered or less studied variants of the conventional perovskite structure, characterized by distinctive properties and potential for diverse applications such as ferroelectric, optoelectronic, and thermoelectric uses. In recent years, advancements in computational methods have markedly expedited the discovery and design of innovative perovskite materials, leading to numerous pertinent reports. However, there are few reviews that thoroughly elaborate the role of computational methods in studying novel perovskites, particularly for state-of-the-art perovskite categories. This review delves into the computational discovery of novel perovskite materials, with a particular focus on antiperovskites and chalcogenide perovskites. We begin with a discussion on the computational methods applied to evaluate the stability and electronic structure of materials. Next, we highlight how these methods expedite the discovery process, demonstrating how rational simulations contribute to researching novel perovskites with improved performance. Finally, we thoroughly discuss the remaining challenges and future outlooks in this research domain to encourage further investigation. We believe that this review will be highly beneficial both for newcomers to the field and for experienced researchers in computational science who are shifting their focus to novel perovskites.

Barriers and Facilitators to Implementing Keep It Up!, A Digital Health Intervention, in Community-Based Organizations.

Despite ongoing investments in the development and testing of new digital interventions for HIV prevention, the widespread use of interventions with proven effectiveness remains limited. This study assessed real-world implementation of a digital HIV prevention intervention, Keep It Up!. The study aimed to identify barriers and facilitators to implementing Keep It Up! within community-based organizations (CBOs) serving racially diverse sexual and gender minoritized populations. The Keep It Up! trial is a type III effectiveness-implementation hybrid trial to compare two delivery approaches: direct-to-consumer and CBO-based implementation. This manuscript focuses on the CBO-based approach through interviews with CBO staff members before and during implementation (n = 37 and n = 25, respectively). Interviews were coded according to the Consolidated Framework for Implementation Research and thematically analyzed. Staff highlighted adaptability, leadership engagement, compatibility, and organizational culture as facilitators of Keep It Up! implementation. Identified barriers included self-efficacy, motivation, staff turnover, and partnerships and connections. CBO infrastructure, capacity, research experience, and processes influenced the relative importance of these barriers and facilitators. This study is one of the first to detail barriers and facilitators experienced by staff implementing a digital HIV prevention intervention in CBOs. Interviews illuminated the need for interventions like Keep It Up! for young men who have sex with men and detailed the need for additional strategies to assist CBOs unfamiliar with implementing digital health interventions. Trial Registration Number: NCT03896776.

Enhancing linguistic research through AI-powered reference management: A proposal for a voice-controlled academic assistant

In today’s digital age, the amount of available research literature is growing exponentially, making it more challenging for researchers to efficiently manage and cite relevant sources. This issue is particularly pronounced in fields like linguistics, where scholars must contend with interdisciplinary sources spanning linguistics, psychology, and computer science. This paper proposes the development of an AI-powered, voice-controlled academic assistant aimed at enhancing the research experience for linguists by streamlining the literature review and citation process. The assistant would use natural language processing (NLP) and machine learning to allow researchers to search for, retrieve, and cite references using voice commands, thereby eliminating many of the tedious aspects of academic research. This proposal outlines the current state of voice-controlled technology, discusses how these technologies can be implemented in academic workflows, and presents a roadmap for the development of a linguist-friendly reference management system. By addressing key technical, ethical, and practical concerns, this paper offers a compelling vision for the future of linguistic research, powered by AI.

Lithosphere infiltrometer: A low cost, automated infiltrometer (permeameter) for measurement of soil health, infiltration, and hydraulic conductivity

Accurate measurement of infiltration rate and hydraulic conductivity is important for assessing soil physical health, irrigation management and catchment modelling. Commercially available infiltrometers are often expensive, fragile, and require specialist knowledge to operate and perform complex post-measurement calculations. We developed the Lithosphere Infiltrometer (permeameter) to be usable for both experienced soil researchers, and users without prior technical or scientific expertise in soil science. The Lithosphere Infiltrometer is able measure both surface and subsoil infiltration rate and hydraulic conductivity. It is manufactured using 3D-printed parts and off-the-shelf electronic components. It has a robust, quad-leg design that allows for rapid leveling of the device and accurate setting of water depth via a novel 3D-printed bell chamber. The water level is measured using a U85 JRT laser with ±1 mm accuracy connected to an Adafruit Huzzah 32 microcontroller. Infiltration rate and hydraulic conductivity are calculated at 1 to 10 min time steps, and data is presented in real-time on an OLED display. Data is stored on the device and available for download to a mobile device by Wi-Fi.

Harnessing the Experience of Research and Indigenous Knowledge for Sustainable Agricultural Transformation in Arunachal Pradesh, India

Traditional knowledge includes methods for nutrient management that rely on natural resources and minimize reliance on artificial inputs. Techniques such as using botanical extracts like Bilb Rasyan and Gaajar Ghaas Svaras, as well as incorporating organic materials like cow urine and plant residues, help enrich the soil with essential nutrients. Farmers in various regions have implemented ITK practices for soil conservation. For instance, the use of Vetiver grass as a vegetative barrier helps prevent soil erosion and stabilizes slopes. This method is cost-effective and adaptable to different environmental conditions. Advocating for policies that recognize and support the integration of ITKs into mainstream agricultural research and extension services is crucial. The Protection of Plant Varieties and Farmers' Rights Act (PPVFR Act) in India provides legal recognition and protection for traditional knowledge and farmer innovations. The synthesis of Indigenous Technical Knowledge and modern agricultural research not only supports the livelihoods of local farmers but also contributes to environmental health and cultural preservation. This approach holds the promise of a more sustainable and prosperous future for Arunachal Pradesh and can serve as an inspiring model for other regions seeking to harmonize tradition with innovation.

An undergraduate research experience in CRISPR-Cas9 mediated eukaryotic genome editing to teach fundamental biochemistry techniques.

CRISPR-Cas9 technology is an established, powerful tool for genome editing through the ability to target specific DNA sequences of interest for introduction of desired genetic modifications. CRISPR-Cas9 is utilized for a variety of purposes, ranging from a research molecular biology tool to treatment for human diseases. Due to its prominence across a variety of applications, it is critical that undergraduates in the life sciences are educated on CRISPR-Cas9 technology. To this end, we created an intensive eight-week long course-based undergraduate research experience (CURE) designed for students to understand CRISPR-Cas9 genome editing and perform it in Saccharomyces cerevisiae. Students enrolled in the CURE participate in 2, 3-h sessions a week and are engaged in the entire process of CRISPR-Cas9 genome editing, from preparation of genome editing reagents to characterization of mutant yeast strains. During the process, students master fundamental techniques in the life sciences, including sterile technique, Polymerase Chain Reaction (PCR), primer design, sequencing requirements, and data analysis. The course is developed with flexibility in the schedule for repetition of techniques in the event of a failed experiment, providing an authentic research experience for the students. Additionally, we have developed the course to be easily modified for the editing of any yeast gene, offering the potential to expand the course in research-driven classroom or laboratory settings.

Neighbors’ Perceptions of University Engaged “Research”

We investigate community members’ perceptions of their engagement with university researchers’ engaged research conducted in their neighborhoods. Analyzing interviews, first, we find perceptions are not simply developed from singular experiences, personal experiences, or even research experiences. Most interviewees did not, or could not, clearly distinguish engaged research from other university activities. They also regarded the university as a monolith. Second, perceptions were related to broad narratives that endure over time and differed by neighborhood and by racialized group. This implies that university engagement in communities should seek to understand current and historical relationships while setting clear expectations with community members.

Stebėjimo metodo ypatumai muziejų auditorijos elgsenos tyrimuose

Audience behaviour research is one of the most relevant topics in the field of museology, as visitor-oriented modern-museology-based museums inevitably need to understand how visitors learn, explore and understand museum information and communication. The article discusses the specifics of the application of observation as one of the oldest scientific research methods in the study of museum audiences. Even though observation is identified as an essential way of studying audience behaviour in real-time, the application of the method still raises questions about the way it is applied, issues of objectivity and the reliability of data. This paper aims to highlight relevant methodological issues in the application of observation and other qualitative methods of museum visitor research in assessing the relationship between the essential research question and the data needed to answer it. A literature review and the results and experiences of the empirical research conducted for the doctoral thesis are used to answer the questions. The empirical study of visitors’ free choice behaviour in the Lithuanian Museum is used to illustrate the relevant features of the monitoring method, while the detailed results of the visitor behaviour monitoring study are presented in a dedicated paper.

Research Attitude, Achievement Motivation, and Self-Efficacy Among Post-Graduate Students Specializing in Primary Education

This study investigates the research attitude, achievement motivation, and self-efficacy concepts among post-graduate students specializing in primary education. The research aims to understand the interplay between these constructs and their implications for academic success and research engagement. A quantitative research design was employed, and data were collected using structured questionnaires from a sample of 62 post-graduate students. Descriptive statistics, and correlation analyses were conducted to examine the relationships between research attitude, achievement motivation, and self-efficacy. Statistical analyses showed non-significant correlations: between research attitude and achievement motivation (Kendall's tau_b = -.048, p = .881; Spearman's rho = -.036, p = .939), achievement motivation and self-efficacy (Kendall's tau_b = -.109, p = .708; Spearman's rho = -.204, p = .629), and research attitude and self-efficacy (Kendall's tau_b = .293, p = .362; Spearman's rho = .360, p = .427) among post-graduate students. The findings contribute to a better understanding of the factors influencing post-graduate students' research experiences and offer insights for academic institutions to enhance support mechanisms for student researchers. The implications of the study underscore the importance of fostering positive research attitudes, strengthening achievement motivation, and enhancing self-efficacy among post-graduate students specializing in primary education. Targeted interventions can optimize academic support and promote professional development in research-intensive environments

Navigating HIV research among criminalized gender minority populations in Uganda: qualitative insights and lessons learned from novice researchers

BackgroundTransgender individuals often face stigma, discrimination, and various forms of abuse, which negatively impact their mental and physical health. They face a significantly greater risk of HIV, with a higher prevalence than the general population. Despite these challenges, transgender people have limited access to healthcare due to violence, legal barriers, and societal stigma, further exacerbated in countries like Uganda, where transgender identities are criminalized. Therefore, this study explored the lived experiences of HIV researchers working with gender minority populations in criminalizing contexts.MethodsThis was an interpretative phenomenological analysis (IPA) qualitative study. Twelve (12) research team members at all levels were involved in the study. Participants had less than five years of involvement in HIV research among gender minority populations. Data were collected using field notes, reflective journals, documentation from daily team debriefing sessions, and semi-structured interviews. The analysis used NVivo software.ResultsPositive experiences, barriers, and challenges were captured. The positive experiences were ‘respecting cultural diversity’, ‘expanding networks’, ‘addressing misconceptions’ and ‘finding allies’. The barriers included ‘experiencing stigma’, ‘lengthy research processes’, ‘feeling isolated’, ‘fearing for personal safety’, ‘unexpected logistical costs’, and ‘criminalization of sexual and gender minorities’. The key themes that emerged from the lessons learned were: ‘dealing with gatekeepers’, ‘diversity and sensitivity training’, ‘leveraging networks’, ’meaningful community engagement’, ‘reflexivity’, ‘ensuring safety’, ‘equal partnership’, ‘giving feedback’ and ‘awareness of legal implications’.ConclusionsThis study highlights the importance of cultural sensitivity, community engagement, and reflexivity in research design and implementation. The findings emphasize the need for innovative strategies to navigate legal, social, and logistical barriers that researchers and participants face. Despite these challenges, the study demonstrates that meaningful collaboration with community members and building trust can significantly enhance the research process and outcomes. Future research should continue to explore these strategies while addressing ethical and safety concerns.

Language teacher expertise research: A theoretical case and research agenda

Abstract Expertise exists among all communities of educational practitioners at all levels and in all national contexts. By identifying expert practitioners, learning from them and valuing their professional competence, researchers can support, promote and build upon sustainable, embodied, holistic models of quality in ways that have direct relevance for the classroom, the curriculum and wider educational goals. Yet, despite its potential as a field of research, there have been relatively few studies involving expert language teachers to date. After a brief historical background, this article makes the case for language teacher expertise research, noting its high ecological validity, its great practical utility, its ability to bridge the research–practice divide and its potentially positive impact on teaching communities. Key methodological considerations are also discussed, including defining expertise, identifying expert teachers and looking beyond the limits of subject-specific pedagogy to understand the whole practitioner in their sociocultural context. The article then proposes a framework for future teacher expertise research that spans diverse methodologies. Six example research tasks from within this framework are proposed, each justified and exemplified, incorporating suggestions for research design that are intended to encourage both experienced and novice researchers to engage with teacher expertise as a promising domain for future investigation.

The invisible community in contemporary China: a visual narrative framework for Chinese lesbian identity

This study employs the photo-elicitation (PE) interview method to explore the social construction of contemporary Chinese lesbian identity. It examines how individuals use visual symbols in their daily lives to construct and express their sexual orientation. The research highlights the diversity and creativity in Chinese lesbian identity expression, while addressing challenges from traditional family values, gender norms, and evolving social attitudes. Introducing the “Visual Narratives of Identity” (VNI) framework, this study bridges the gap between academic research and lived experiences, offering insights into identity expression under social and cultural constraints. The findings emphasize the complex strategies participants use to navigate social expectations and maintain personal authenticity. This study enriches the theoretical landscape of sexual orientation identity in visual culture studies, advocates for methodological diversity, and deepens our understanding of the complexities within Chinese lesbian subcultures.

Not me-search, you-search: Ethical considerations for research involving marginalized outgroups

ABSTRACT Background:This study explored experiences of quantitative researchers who work with marginalized populations. Methods/materials: Participants were recruited from the Society for Personality and Social Psychology forum, and asked questions regarding their struggles and best practices while working with marginalized populations in which they are or are not a member. Results: Responses included concerns regarding bidirectional trust, community norms, perceived bias, diversity and participant recruitment and compensation. We explore the benefits of qualitative understandings of bias (i.e. positionality, reflexivity), salient concerns reported by quantitative researchers, and our recommendations for the ethical inclusion of these practices across quantitative work. Conclusions: This paper contributes to understanding of current struggles and best practices while conducting research among marginalized populations. Additionally, we encourage quantitative researchers to engage in reflexive research practices, particularly for the benefit of marginalized group research. We extend the insider-outsider researcher discussion to quantitative researchers.

7216 Absence Of Weight Gain In C57Bl/67 Female Mice On A High-Fat Diet Protects The Skeleton From Bone Loss

Abstract Disclosure: C. McAndrews: None. C. Chlebek: None. S. Costa: None. C.J. Rosen: None. Background: Obesity is associated with both systemic metabolic changes that increase the risk of comorbidities and reduced bone quality that increases the risk of fracture. The effects of high-fat diet consumption have been well studied in preclinical models where high-fat diet-feeding induces obesity, but there have been no studies to investigate the effects of high-fat diet-feeding in animals that do not become obese. Therefore, we characterized components of systemic metabolism and bone mineral content in non-obese C57Bl/6J mice that were fed a high-fat diet. Methods: Female C57Bl/6J mice aged 8 weeks received either a high-fat (60% kcal fat, n = 31) or control (10% kcal fat, n = 17) diet for 12 weeks. Body composition, areal bone mineral density (BMD) and bone mineral composition (BMC) were assessed after the feeding period using dual energy x-ray absorptiometry (Faxitron UltraFocus-DXA). Glucose (GTT) and insulin (ITT) tolerance testing were performed at the conclusion of the study. Changes in body weight were calculated as the difference between baseline and experiment end. High-fat diet-fed animals were classified as obese (HFD-O, n = 24) if they weighed more than 25 g or had greater than 25% body fat as evaluated via DXA, and were otherwise considered non-obese (HFD-NO, n = 7). In a small subset of animals, subcutaneous inguinal fat pads were harvested and weighed (n=5-7/group). Differences between groups were assessed with one-way ANOVAs and Tukey post-hoc analyses. Results: HFD-O mice weighed more than HFD-NO and control animals, whereas the body weights of HFD-NO mice were not significantly different from control (p < 0.001). Fat percent was increased in HFD-O mice compared to HFD-NO and control animals (p < 0.001). Subcutaneous inguinal fat mass was increased in both HFD-O and HFD-NO mice compared to control (p < 0.001). Fasting blood glucose did not significantly differ between groups. Glucose tolerance was worsened in both HFD-O and HFD-NO mice compared to control (p < 0.001), but there were no significant differences in insulin tolerance between groups. BMD was decreased in HFD-O mice compared to HFD-NO and control animals (p < 0.001). DISCUSSION: The consumption of a high-fat diet in mice induces deleterious metabolic changes irrespective of weight gain. However, high-fat diet-induced bone loss does not occur in the absence of weight gain. These findings suggest that certain adipokines derived from larger adipose depots may drive high-fat diet-induced bone loss and warrant further investigation.
