This paper examines the zooplankton abundance and composition along with various environmental factors in Lake Arekit – a shallow freshwater habitat in Ethiopia's rift valley system. Zooplankton samples and specific environmental data were collected by a seasonal campaign (rainy season: June to August) and dry season: March to May 2023) from three sites: inlet area (IA), pelagic area (PA), and macrophyte area (MA). In total, 11 zooplankton taxa from four different groups – rotifera (7 taxa), cladocera (2 taxa), copepod (1 taxa), and ostracoda (1 taxa) – were identified in Lake Arekit. Large-bodied copepoda and cladocera comprised 90% of the zooplankton density in the lake, but small-bodied rotifers dominated the zooplankton diversity. The most noticeable zooplankton in the lake were Mesocyclops aequatorialis, Daphnia barbata, and Cypridopsis vidua. Seasonal difference in the total zooplankton abundance was evident (p < 0.01): being high during the rainy season which was accompanied by an increase in the lake's water temperature and nutrient levels. At MA, where D. barbata predominated, chlorophyll a was relatively low. Chlorophyll a had a strong negative correlation with the abundance of grazing zooplankton, especially with D. barbata (r = −0.563) and C. vidua (r = −0.518). The zooplankton composition and abundance of Lake Arekit reveal a low Shannon diversity index (H') (1.03) and a predominance of a few species, indicating heavy contamination of the lake's water. Moreover, Lake Arekit was determined to be hypertrophic (TSI > 70) using Carlson's trophic index (TSI), which took into account the lake's water transparency, total phosphorus, and chlorophyll a. Our results indicated that high densities of Daphnia should be the goal of biomanipulation since they can achieve filtration potentials high enough to enhance the water's clarity in hypereutrophic lake. Even though high D. barbata concentrations cannot address the underlying cause of eutrophication, grazing can assist by lengthening the clear-water stages in a hypertrophic lake – Lake Arekit. The sources of pollution for the lake are the discharge of wastewater from nearby water bottling companies and possibly high nutrient levels from the lake's geological history. Stopping the discharge of wastewater from the nearby commercial industries (the major source of contaminant) into heavily washed open areas and establishing a buffer zone may help manage the water quality of Lake Arekit.

Endophytic fungi occupy inner plant tissues, which results in various interactions between the fungus and host. Studies on endophytic fungi have been conducted in Korea for over 30 years. This paper summarizes the published results of those studies. The endophytic fungi of approximately 132 plant species in Korea have been studied since the 1990s, resulting in over 118 publications. The host plants featured in these studies comprised 3 species of mosses, 34 species of woody plants, and 95 species of herbaceous plants. At the family level, the most studied plants were members of the Poaceae family, covering 18 species. Regionally, these studies were conducted throughout Korea, but over half of the studies were conducted in Gyeongsangbuk-do, Gangwon-do, and Chungcheongnam-do. Relatively few studies have been conducted in a metropolis such as Seoul. We confirmed 5 phyla, 16 classes, 49 orders, 135 families, 305 genera, and 855 taxa of endophytic fungi, excluding Incertae sedis, whose relationship with others are unknown. Most of the endophytic fungi belonged to Ascomycota (93.2%), and a few belonged to Basidiomycota (3.6%). Since the diversity of endophytic fungi differs depending on the host plant, plant tissue, and distribution region, future studies should be conducted on multiple host plants and in various regions. Future studies on endophytic fungi are expected to broaden, including genomics and taxonomic and ecological studies of secondary metabolites. [ABSTRACT FROM AUTHOR]

Research productivity is expected of academic faculty, and mentoring can facilitate it. This paper presents a framework for using mentoring to develop researchers in health disciplines. We utilized recent literature reviews, and experience developing researchers at an emerging research institution within the Research Centers for Minority Institutions (RCMI) program, to propose a precision mentoring (PM) framework for research development. Although we cannot precisely determine how much improvement was due to the PM framework, over the 4 years of our program, the quality and quantity of pilot project proposals (PPP) has increased, the number of external proposals submitted and funded by PPP investigators has increased, and the number of faculty participating in our program has increased. Surveys distributed to our 2021–22 PPP applicants who did not receive funding (n = 5/6 or 86.7%) revealed that new investigators most frequently sought mentoring related to career guidance (e.g., institutional culture, pre-tenure survival strategies), grant proposal basics (e.g., working with funding agencies, reviewing aims, balancing priorities, and enhancing scientific rigor), and identifying funding opportunities. We recommend shifting the mentoring paradigm such that: (a) mentees are pre-screened and re-screened for their current skill set and desired areas of growth; (b) mentoring occurs in teams vs. by individuals; (c) mentors are trained and rewarded, and (d) attention is paid to enhancing institutional culture.

AMERICAN women ,AUTOPHAGY - Abstract
Over the past several years, I have been interacting with an increasing number of Iranian scientists, including those currently living in Iran as well as others who are being educated elsewhere or have independent positions outside of that country. In all circumstances, the resulting collaborations have extended my own knowledge and allowed me to contribute to papers on a variety of topics that are outside my specific area of expertise, including xenophagy, nanoparticles, cardiac disease and cancer. As the editor-in-chief of this journal, one of my goals is to be as inclusive as possible, encouraging scientists from around the world to engage in autophagy-related research, and to heighten awareness of this work with an aim toward a more complete understanding of the basic process, and to aid in progress toward the modulation of autophagy for medical applications. For this reason, I have been extremely dismayed by the actions of the current government in Iran, which have led to attacks on scientists and students, and in particular to policies that encourage the repression of women. Although we still have not achieved full equality for women in the United States of America, I think we are slowly moving in a positive direction. It is my sincere hope that the lives and aspirations of women around the world can continue to improve so that this half of our population can fully contribute to the scientific enterprise.

MARINE fungi ,BRACKISH waters ,MARINE habitats ,SEAWATER ,BASIDIOMYCOTA - Abstract
Vast parts of the Baltic Sea have been mycologically neglected and are still awaiting exploration. Here we summarise earlier records of marine fungi from the Baltic, supplementing them with discoveries from fieldwork in Sweden in 2019. Although marine fungal diversity is clearly attenuated in the brackish water of the Baltic Sea, a substantial number has still been discovered. Here we list 77 species from the Baltic Sea, whereas after a critical assessment a further 18 species have been excluded as records of marine fungi. The species have mainly been identified by their morphological features, supplemented by DNA-based diagnostics. Most of the species have their main distributions in temperate areas of the Atlantic Ocean. Some of the Baltic species discovered here represent far disjunctions to tropical waters while only a very few are until now only recorded for the Baltic Sea. In this paper two species belong in Basidiomycota, while the most ascomyceteous speciose classes are Sordariomycetes (with 42 species) and Dothideomycetes (24). Halosphaeriaceae is the most speciose family in marine habitats, as also in the Baltic Sea, represented here by 29 species. Three species are new to Europe, and in addition 13 to the Baltic Sea and 13 to Sweden. [ABSTRACT FROM AUTHOR]

DIVERSITY in organizations - Abstract
New Zealand tertiary ethics committees may work from similar ethical principles but this article demonstrates that the way in which they operate is idiosyncratic. The paper builds on commentaries offered by current or former members of five New Zealand ethics committees on the organisation and practices of their committees. It examines differences among the committees with the aim of initiating an ongoing conversation about the work of ethics committees in the New Zealand context. It argues for the merits of diversity, transparency and openness as core principles for the work of ethics committees and as a platform for dealing with critique. [ABSTRACT FROM PUBLISHER]

BOARDS of directors ,ORGANIZATIONAL performance ,CORPORATE governance ,STOCKHOLDERS ,FINANCIAL performance - Abstract
This paper analyses the structure of boards of directors and its impact on business performance, which is approximated by economic profitability and the Tobin's Q ratio. We focus on three basic aspects of boards that have been reviewed in the recent reform of the Good Governance Code: the size of boards, their independence and their diversity. For the study of diversity, we use an index that integrates not only the gender of board members, but also their age and nationality, since these are factors that can influence the knowledge, experience and skills of the directors. The results confirm a high degree of compliance with the recommendations of the Good Governance Code, and suggest that the performance of the advisory and monitoring functions are factors that determine the composition of boards. With respect to the performance of the company, we note that there is a negative and significant relationship with the independence of boards. However, the results are sensitive to the performance measure employed. [ABSTRACT FROM AUTHOR]

Background:This paper is the product of a two year investigation into the contribution of post-16 education to community cohesion. The investigation took place between 2010 and 2012 and was funded by the University Centre at Blackburn College in England. Fieldwork was undertaken in three East Lancashire colleges and focused on students aged between 16 and 19 years. Purpose: The aims of the paper are to identify the nature of community cohesion initiatives in East Lancashire’s post-16 sector and to establish the extent to which these initiatives are successful in uniting students from different ethnic, cultural and religious backgrounds. The paper discusses student attitudes towards community cohesion and the role of further education colleges in shaping these attitudes. Sample: The data were collected from nine in-depth interviews with college lecturers and managers and from a questionnaire survey of 355 students. The research was conducted in two further education colleges and a Roman Catholic sixth form college. All three colleges were overwhelmingly dual-ethnic, with white and Asian students making up the majority of the college populations. Design and methods: The methods used throughout the investigation were threefold: (1) a review of the literature on the role of further education colleges as agents of community cohesion, (2) nine semi-structured interviews with college lecturers and managers, and (3) a closed-response questionnaire distributed to 355 further education students. Results: (1) While all three colleges referred to community cohesion in their policy documents, there was an absence of explicit community cohesion strategies. (2) Although there was clear evidence of cultural, ethnic and religious diversity in the three colleges, there was significant variation in cohesion initiatives. Most students, however, recognised the importance of cohesion and felt that, at the macro level, their colleges operated in an inclusive and cohesive manner. (3) At the more micro level, divisions between students were pronounced, evidenced by very little cross-cultural mixing either in or outside classrooms. (4) While over 50% of the survey respondents were unable to offer examples of cohesion initiatives in which they had been involved, around 45% stated that they had learnt about issues such as equality, diversity and integration during their time at college and that this had had a positive effect on their attitudes. Conclusions: The findings both support and refute the contention that further education colleges can make a worthy contribution to community cohesion. For the most part, levels of cohesion are contingent on recruitment of students from different backgrounds and on the ability of teachers and lecturers to impart positive messages about integration and social unity. At the same time, the investigation exposes a dissonance between the value that students claim to place on community cohesion and their ability and/or desire to bring this cohesion about. These conclusions have important implications for pedagogy and for the professional development of those employed in the post-16 sector. [ABSTRACT FROM PUBLISHER]

The gap between educational outcomes and labour market demand is one of the most important issues concerning researchers and specialists in the field of educational planning and policy-making. Innovation, entrepreneurship, diversity and creativity characterize the globalized, high-tech labour markets. Whilst striving for a sustainable future, Oman is still grappling with entrenched, traditional methods of education. These educational methods are incapable of meeting diverse learning needs or producing young people, equipped to readily take their places in the workforce. Structured interviews with key figures in Oman were conducted to gauge the prospect of a vision of education which encompasses alternative schools, programmes and pathways to enhance opportunities for all students and facilitate outcomes that better match demands created by an increasingly sophisticated working environment. This paper is produced at a time when planning is underway for Vision 2040 and provides insight into the challenges and opportunities for alternative education in Oman. [ABSTRACT FROM AUTHOR]

The student population across world is increasingly reflective of diverse cultures, religions and ethnicities. This rich diversity may become a challenge for educational leaders, teachers, and policy-makers in the absence of an understanding of diverse sources of knowledge people draw on for directing their beliefs and daily practices. This paper explores the multi-ethnic context in Britain with a focus on Muslim students in English secondary schools, and argues for drawing on diverse ethnic knowledge sources to inform and enrich approaches towards managing diversity. It discusses the concept of Adab derived from Muslim ethics and philosophy, and debates possible contributions of such conceptual adaptations towards improving educational engagement and performance.

There is a global demand for construction managers, and an undergraduate degree in a construction-related field offers some of the best prospects for entry into the profession. However, despite demand, undergraduate construction education programs continue to lack racial-ethnic diversity. This longitudinal case study explores and compares 1990 through 2009 and 2010 through 2017 enrollment trends and academic success outcomes (e.g. GPA and graduation rates) among undergraduate Latino/Hispanic and racially minoritized students and their respective peers at a large construction management program in the western United States (n = 3373). Statistically significant differences in academic success outcome variables, shown in literature to indicate evidence of opportunity gaps, were observed between groups. Furthermore, it was noted that the magnitude of some of these mean differences were larger between 2010 and 2017 when compared to the mean differences between 1990 and 2009. Recommendations, future research, limitations, and interpretation of the results are discussed. [ABSTRACT FROM AUTHOR]

Global climate change has led to more frequent and severe droughts, which can negatively affect instream invertebrate communities, but we lack a perspective on the global patterns and drivers of such drought effects. Here, using meta-analysis, we synthesized 997 paired observations extracted from 94 peer-reviewed publications to assess how drought affects the biomass, density, taxonomic richness, and diversity (Shannon–Wiener, Simpson, and Pielou indices) of instream invertebrates at a global scale. We found that (i) drought significantly decreased instream invertebrate density and taxonomic richness by an average of 4.9 and 5.0%, respectively, had marginal negative effects on Shannon–Wiener index, but did not affect biomass, Simpson index or Pielou index; (ii) the effects of drought on instream invertebrate biomass, density, and diversity were not affected by taxonomic level, indicating the robustness of our results; and (iii) stream water physiochemical characteristics such as water flow velocity, pH, conductivity, discharge, total nitrogen concentration, and chlorophyll-a concentration were important moderator variables of drought effects on instream invertebrate communities. Overall, our results clearly showed the global patterns and driving factors of drought effects on instream invertebrate biomass, density, richness, and diversity, which helps scientists better understand the responses of instream invertebrate communities under ongoing global climate change.

INCLUSIVE education ,MULTICULTURAL education ,COMPARATIVE method - Abstract
Modern school education consists of a mosaic of over-pluralism of cultures, languages, ethnicities, abilities and other characteristics. Under these circumstances, educational systems face the challenge of providing high-quality educational services in order to maintain and sustain social justice. In this respect, inclusive and intercultural education can be the catalysts of change. Nevertheless, what is argued in this article is the need to overcome the dipole created between the two pedagogical paradigms which often inhibits rather than reinforces social justice. Therefore, we should not approach the two paradigms through discrete focuses, but we should pave the way for a third perspective through a blended and comparative approach. At the same time, we make the case that sustainability should become the cornerstone of such endeavour, leading to Sustainable Intercultural and Inclusive Education (SIIE) aiming to benefit all students not only of this but of future generations.

Background: Women and underrepresented in medicine and the health sciences (URiM) faculty face inequities in advancement. Career sponsorship may be a remedy. Few studies have described sponsorship in academic medicine and none across an institution. Objective: To examine faculty awareness, experiences, and perceptions of sponsorship at a large academic health center. Design: Anonymous online survey. Participants: Faculty with a ≥50% appointment. Main Measures: The survey contained 31 Likert, multiple-choice, yes/no, and open-ended questions about familiarity with the concept of sponsorship; experience of having or being a sponsor; receipt of specific sponsorship activities; sponsorship impact and satisfaction; mentorship and sponsorship co-occurrence; and perception of inequities. Open-ended questions were analyzed using content analysis. Key Results: Thirty-one percent of the surveyed faculty (903/2900) responded of whom 53% (477/903) were women and 10% (95/903) were URiM. Familiarity with sponsorship was higher among assistant (91%, 269/894) and associate (182/894; 64%) professors versus full professors (38%, 329/894); women (67%, 319/488) versus men (62%, 169/488); and URiM (77%, 66/517) versus non-URiM faculty (55%, 451/517). A majority had a personal sponsor (528/691; 76%) during their career and were satisfied with their sponsorship (64%, 532/828). However, when responses from faculty of different professorial ranks were stratified by gender and URiM identity, we observed possible cohort effects. Furthermore, 55% (398/718) of respondents perceived that women received less sponsorship than men and 46% (312/672) that URiM faculty received less than their peers. We identified seven qualitative themes: sponsorship importance, growing awareness and change, institutional biases and deficiencies, groups getting less sponsorship, people with sponsorship power, conflation with mentorship, and potential for negative impact. Conclusions: A majority of respondents at a large academic health center reported sponsorship familiarity, receipt, and satisfaction. Yet many perceived persistent institutional biases and the need for systematic change to improve sponsorship transparency, equity, and impact. [ABSTRACT FROM AUTHOR]

Purpose. Lack of health care providers' knowledge about the experience and needs of individuals with disabilities contribute to health care disparities experienced by people with disabilities. Using the Core Competencies on Disability for Health Care Education, this mixed methods study aimed to explore the extent the Core Competencies are addressed in medical education programs and the facilitators and barriers to expanding curricular integration. Method. Mixed-methods design with an online survey and individual qualitative interviews was used. An online survey was distributed to U.S. medical schools. Semi-structured qualitative interviews were conducted via Zoom with five key informants. Survey data were analyzed using descriptive statistics. Qualitative data were analyzed using thematic analysis. Results. Fourteen medical schools responded to the survey. Many schools reported addressing most of the Core Competencies. The extent of disability competency training varied across medical programs with the majority showing limited opportunities for in depth understanding of disability. Most schools had some, although limited, engagement with people with disabilities. Having faculty champions was the most frequent facilitator and lack of time in the curriculum was the most significant barrier to integrating more learning activities. Qualitative interviews provided more insight on the influence of the curricular structure and time and the importance of faculty champion and resources. Conclusions. Findings support the need for better integration of disability competency training woven throughout medical school curriculum to encourage in-depth understanding about disability. Formal inclusion of the Core Competencies into the Liaison Committee on Medical Education standards can help ensure that disability competency training does not rely on champions or resources.

This paper explores the complex and shifting dimensions of the social, cultural and bodily differences that impact on learners and their learning. Our theoretical argument proceeds in five stages. First, we build a typology of terms used to classify demographic differences for the purposes of designing, implementing and evaluating the effectiveness of educational institutions and programs: material conditions (social class, locale and family); corporeal attributes (age, race, sex and sexuality, physical and mental abilities); and symbolic representations (language, ethnos, communities of commitment and gendre). Second, we address the paradigms of civic association that modern nation-states have used to negotiate these differences: exclusion, assimilation and an aspirational regime that we call 'civic pluralism'. Third, we explore complications that render the demographic categorizations problematic. Fourth, we propose an alternative and supplementary frame for social and learner differences based on 'lifeworld differences'. Finally, we explore the ways in which civic pluralism might be translated into educational practice. We interleave these theoretical explorations with an analysis developed for an evaluation of an inclusive education program in Roma communities in Northern Greece. The Roma serve as a case study of the complex ways in which categories of difference play out in social and educational reality. [ABSTRACT FROM AUTHOR]

Melbourne's population is diverse and predicted to grow rapidly; its infrastructure must reflect these changes. Engineers have a responsibility to create solutions to this phenomenon that cater to the diverse needs of their users. The current political appetite for infrastructure development presents an opportunity to improve Melbourne's ability to accommodate everyone by applying inclusive solutions to infrastructure design, improving the overall sustainability and liveability of Melbourne. In the engineering industry, infrastructure often reflects those designing it, and not the society it intends to serve. This must change if the benefits of infrastructure and associated economic investments are to be fully realised. From a strategic standpoint, social, legislative, economic and political consequences will impact the city long into the future. This paper discusses the extent to which Melbourne is an 'inclusive city' and aims to explore how the city can apply inclusive solutions in the context of diversity and in future infrastructure investment. It considers how opportunities for inclusiveness in infrastructure may be restricted by the homogeneity of the engineering industry, and the importance of fostering diversity in engineering to combat this phenomenon. It suggests practical solutions to achieve a holistic approach to inclusivity, supplementing Melbourne's existing strategic frameworks and policies. [ABSTRACT FROM AUTHOR]

Phytophthora species, classified under Oomycota, cause significant damage to various crops and trees. The present study introduced Phytophthora species, P. nagaii and P. tentaculata, new to Korea, which pose notable risks to their respective host plants. Our research provided a comprehensive description of these species taking into account their cultural features, morphological characteristics, and molecular phylogenetic analysis using the internal transcribed spacer rDNA region and cytochrome c oxidase subunit mtDNA genes (cox1 and cox2) sequences. In addition, this study first evaluated the sensitivity of P. nagaii and P. tentaculata to five anti-oomycete fungicides, finding both species most responsive to picarbutrazox and P. tentaculata resistant to fluazinam. The data can guide targeted treatment strategies and offer insights into effective control methods. The findings expand our understanding of the diversity, distribution, and management of Phytophthora species in Korea. [ABSTRACT FROM AUTHOR]

Two-year colleges provide the opportunity for students of all ages to try new subjects, change careers, upskill, or begin exploring higher education, at affordable rates. Many might begin their exploration by taking a course at a local two-year college. Currently, not many of these institutions in the U.S. offer data science courses. This article introduces the perspective lens of students who have gone through the Montgomery College Data Science Certificate Program. We found that, contrary to many other educational fields at the College, data science students tend to come from diverse backgrounds and career paths. A common theme emerged that all students learned valuable skills and applications such as coding in various programming languages and approaches to machine learning. Other meaningful themes included an appreciation of course accessibility, especially catered toward busy professionals who might only be able to take evening courses. Students appreciated learning that data science and ethics are intertwined. Finally, it was evident that going through the data science program positively impacted the lives and careers of these students. The implications of the themes of these student experiences are discussed as they relate to data science education. for this article are available online. [ABSTRACT FROM AUTHOR]

Eating a diverse diet is an internationally accepted recommendation for a healthy diet. The food-based dietary guideline (FBDG) “Enjoy a variety of foods” aims to encourage people to consume mixed meals, to increase variety by eating different foods from various food groups, and to alter food preparation methods. This position paper suggests ways of measuring dietary variety, addresses the consequences of poor dietary variety in South Africa, and provides results pertaining to dietary variety in South African children and adults. The literature reveals that dietary diversity is best calculated by means of different food groups, which are based on the traditional eating patterns of the population under investigation. Ideally, the recall period should be three days. Two national surveys in South Africa have provided data on dietary diversity scores (DDS) in adults and children, of 4.02 and 3.6 respectively. It was shown that in children, DDS positively relates to weight-for- height z-scores, with a z-score above zero being achieved when DDS is > 4. However, an energy-dense diet is cheaper and lower in micronutrients and also positively associated with increased body mass index in women. Hence, dietary variety is essential in improving the micronutrient intake of the diet, and is also important in preventing obesity. Household food insecurity in South Africa remains a constraint on the implementation of this guideline. This FBDG should be used in conjunction with the other South African FBDGs, to ensure the sufficient intake of food that contains protective factors and the limited intake of food that is known to increase the risk of noncommunicable diseases.

Responding to violations against lesbian, gay, bisexual, transgender, intersex and queer people worldwide, in the light of the universality of human rights, this paper demonstrates the need, benefits and opportunities for including sexual orientation and gender identity (SOGI) in human rights impact assessment (HRIA) and related impact assessments. The United Nations legal framework (including the 2011 Resolution on Human Rights, Sexual Orientation and Gender Identity) and supporting international legal documents such as the Yogyakarta Principles provide the mandate and basis for this paper. The paper develops a typology of documents related to SOGI aspects in HRIA and provides examples of SOGI-centred HRIA approaches, specifically the Uganda Anti-Homosexuality Bill and post-earthquake disaster relief in Haiti. Our findings identify research-practice gaps in modes and technicalities of the pioneer SOGI-centred HRIA cases, and attest to an absence of methodologies, tools and indicators. We call upon impact assessment practitioners to develop and use tools that are inclusive of gays, lesbians and bisexuals as well as transgender and intersex people. [ABSTRACT FROM PUBLISHER]

This paper explores the subtexts of the controversy generated by the hijab in Irish schools and, more specifically, what these reveal about the Irish education system's level of acceptance of (religious) diversity, as assessed on a spectrum of non-toleration, toleration and respect-recognition. Using a critical discourse analysis approach, the study highlights and examines the main argumentative strategies through which the hijab controversy and its repercussions have been constructed and debated in Ireland. These reveal that, while the Irish education system has been able to offer a level of structural and practical accommodation to (religious) minorities - including Muslims - acceptance of religious diversity can be dependent on a number of factors, including the limited nature of the claim and the size of the minority, and is also conditional on the consequences of such diversity for the schools' self-perception.

Background: This paper considers how textbooks resolve the tension between contradictory goals of promoting a cohesive national identity while teaching respect and equality among diverse social groups in British Columbia (B.C.), Canada. Purpose: The article presents preliminary results of a larger study examining the content of required civic education textbooks in Canada to examine whether and how notions of national identity incorporate the principles of human rights and multiculturalism. Sample: The study draws on curricular material for required high school social science courses in B.C. The sample includes textbooks starting the first year of high school (Grade 8) and covers each year through high school graduation (Grade 12). The central analyses examine the content of 17 core textbooks approved by the provincial government for these courses. Design and methods: This research systematically examines the content of currently approved textbooks for high school social science courses in B.C. Aquestionnaire designed using the principles of content analysis measures textbook emphases on content relevant to human rights, multiculturalism and national identity. Results: This study finds that traditional notions of national identity are reshaped in response to the rise of emphases on human rights and multiculturalism. Rather than depicting national identity as stemming from a common race, ethnicity, language or history, the government pursues four main strategies to simultaneously promote human rights, multiculturalism and a shared national identity: (1) framing human rights and multiculturalism as part of national identity; (2) using pedagogical approaches that promote multiple perspectives; (3)celebrating social and scientific figures and accomplishments as a main source of national pride; and (4) drawing on exogenous sources to affirm state legitimacy. Conclusion: In a context that values diversity and human rights, contemporary sources of national identity can stem from facets of society that can transcend many cultures and emphasise organisational aspects of the nation-state. A main implication is that the inclusion of principles of human rights and multiculturalism into civic education is changing traditional conceptions of national identity. [ABSTRACT FROM AUTHOR]

Species, varieties and area of Bt (Bacillus thuringiensis) transgenic crops have increased rapidly worldwide in the past 11 years (1996-2006) for economic, environmental and health benefits. However, the ecological risks of Bt transgenic crops were critically highlighted for potential adverse effects on agroecosystems, in particular, non-target effects on soil microorganisms. Arbuscular mycorrhizal fungi (AMF) are important soil microorganisms providing a range of benefits to the majority of crop plants in the agroecosystem, worthy of monitoring for non-target effects of Bt transgenic crops. Bt transgenic crops may affect AMF in many ways during their life with regard to the temporal-spatial relevance between the occurrence of Bt proteins and fungal symbiotic development of AMF. This may lead to an unwelcome surprise with regard to specific abundance and diversity of AMF when Bt transgenic crops are planted continuously. It is concluded that interactions between AMF and Bt transgenic crops at individual and community level are a new urgent soil ecological issue. Some evidence about Bt transgenic crop effects on AMF revealed by recent articles are summarized, and research prospects are highlighted in the paper. [ABSTRACT FROM AUTHOR]

ANTS ,ANIMAL species ,ANIMAL populations - Abstract
This paper combines published and new collection records to provide a comprehensive list of ant species collected on Tokelau, a Pacific island nation with the world's smallest land area. Twenty-eight ant species have been recorded since the late 1950s, 10 in recent surveys, and the majority of which are tramp species. Known invasive species such as Anoplolepis gracilipes, Monomorium pharaonis, Pheidole megacephala, and Tapinoma melanocephalum are present but currently appear to have a limited distribution on two of the three atolls. There are no ant species endemic to Tokelau, but two Pacific endemics, and 11 Pacific natives; 26 listed ant species are present in Samoa, which is the likely point of origin for most of Tokelau's ant fauna. Pitfall trap collections from three visits between 2002 and 2005 highlight how different sampling intensities and locations alter the species accumulation rate and species richness and diversity estimates. The relationship between total ant species and land area of Pacific islands is linear, but combined with earlier records, this study reports more ant species from Tokelau than the analysis predicts. This study indicates the remote and small nation of Tokelau is as susceptible to invasive species as other larger, more populated, land masses in the Pacific. [ABSTRACT FROM AUTHOR]

When underrepresented and at-risk students feel like they belong, they are more likely to succeed. By measuring and monitoring sense of community, construction programs can identify opportunities for improvement and guide strategies to support the needs of all students. This study measured sense of community within five undergraduate construction programs in the U.S. Midwest. The researchers tested for differences in sense of community between demographic groups based on based on race, gender, first-generation college student status and transfer students status. Differences between groups were further investigated by considering the four elements of community. The results indicate that each school provides a unique environment in regard to community for their students. However, across the sample, lower sense of community was reported for not white and transfer students. The results indicate that within the U.S Midwest, additional efforts are necessary to strengthen community and support the needs of all students in undergraduate construction management programs.

The Caucasian fauna of water bugs (Heteroptera: Gerromorpha, Nepomorpha) is reviewed based on data originating from literature survey, museum and private collections, and extensive field sampling. The diversity of Caucasus ecoregion is quite significant with 77 species and subspecies framed within 25 genera (17 in Nepomorpha, 8 in Gerromorpha), and 13 families (8 in Nepomorpha, 5 in Gerromorpha). Micronecta anatolica anatolica Lindberg, 1922, Sigara iranica Lindberg, 1964, S. samani tigranes Jansson, 1986, Velia kiritshenkoi Tamanini, 1958, and Gerris asper (Fieber, 1860) are reported for the first time from Georgia, M. anatolica anatolica, Notonecta maculata Fabricius, 1794, Mesovelia thermalis Horváth, 1915, and Gerris lacustris (Linnaeus, 1758) represent new records for Armenia, and Microvelia macani Brown, 1953 is new for Azerbaijan. A chorological and similarity analysis highlighted the connections with and between adjacent countries, with Caucasus ecoregion having the highest similarity of the water bug fauna with Turkey, whereas Iran and Russia (European territory) have the lowest. The largest number of shared species/subspecies was found between the Caucasus and Turkey (64 taxa), while the lowest was between Iran and Russia (40 taxa). Our results indicate that the Caucasus represents a composite of various faunal elements of different origin, ranging from Caucasian endemics to Afrotropico-Indo-Mediterranean and Holarctic.

In densely populated, highly urbanized regions such as Zhejiang Province (eastern China), species are under enormous environmental pressures resulting from human activities, land use changes, and habitat fragmentation, which affect species composition and species diversity. Although eastern China is one of the most concentrated distribution areas of endemic bryophytes in East Asia, these species are also faced with the threats of habitat inadequacy. In order to get more information on bryophyte habitat and diversity, we investigated species composition, habitat preference, as well as species diversity differences of bryophytes under different habitat conditions in Jiulongshan National Forest Park (JNFP). In particular, the results showed that 108 specimens of bryophyte were collected in total, including 46 species in 32 genera of 21 families. Furthermore, we had found 12 species of bryophytes that had never been recorded before in Zhejiang Province. Remarkably, 40.74% of bryophytes were found to grow on natural rocks, followed by understories and roadside habitats. In addition, the Patrick richness index (R) varied most significantly among different habitats (p < 0.001). In a conservation perspective, natural rocks, roadways and understories should be preserved to protect bryophyte diversity. [ABSTRACT FROM AUTHOR]

Global decline in biodiversity warrants its systematic monitoring in space and time. Remote sensing derived Rao's Q index has been proposed as a proxy for species diversity yet its scope for seasonal tropical forest is untested. The study assessed the influence of phenology on Rao's Q index derived using multi-date Sentinel-2 NDVI to estimate tree diversity. Plot level vegetation inventory data (n = 61) was used to estimate tree diversity (Shannon-Wiener index (H')) of Nandhaur landscape in North-West Himalayan foothills. Rao's Q index and H' showed lower correlation at the landscape level than individual forest types. Rao's Q index based on NDVI observed higher correlation with H', especially during the leaf flushing period. NDVI-based multi-dimensional Rao's Q index offered better performance for dry deciduous (R
2 =0.69) followed by moist deciduous forest. The present approach can be used for estimating tree diversity, especially in seasonal tropical forests. [ABSTRACT FROM AUTHOR]- Published

Building food system resilience enables the system to buffer, adapt and transform in response to changes. Identification of key variables of resilience support actors and policymakers managing the food systems. The objective of this study was to identify the most important variables to assess food system resilience and actors with the best opportunities to take responsibility for preparing for disruptions. We operationalised the key variables of resilience in the Finnish food system and evaluated them using a Delphi expert method. We produced a framework for food system resilience, including three indispensable interacting levels of action and good practices within each supporting resilience building. In the prioritisation of key variables, diversity in production, versatile cooperation between actors based on trust, independence of external inputs, system understanding, and renewable domestic energy were considered the most important. Research and administration play a key role in producing information and implementing actions targeted especially at agriculture, where actions are expected to be the most efficient and impactful. In the whole food system, increasing transparency would help create trust and thus promote co-creation of sustainable practices. Platforms to obtain information about future risks and for co-creating solutions for building food system resilience are needed. [ABSTRACT FROM AUTHOR]

Currently, there is a lack of Indigenous physicians in the Northwest Territories (NWT), Canada. The goal of this qualitative study was to explore the underlying factors that influence the journey to becoming a medical doctor and returning home to practice for Indigenous students from the NWT. Eight qualitative, semi-structured interviews were conducted by phone or in-person. Participants represented Dene, Inuvialuit and Métis from the NWT and were at varying points in their journey into careers in medicine, from undergraduate university students through to practicing physicians. The main themes identified included access to high-school courses, the role of guidance counsellors, access to mentors and role models, a need to prioritise clinical experience in the NWT, influences of family and friends, diversity and inclusion, and finances. Interpretations: Significant barriers, some insurmountable, remain at every stage of the journey into medicine for aspiring Indigenous medical doctors from the NWT. These findings can inform policy development for pathway programs that assist aspiring Indigenous physicians at each stage. [ABSTRACT FROM AUTHOR]

We report on the discovery of a population related to the Blunt-headed Salamander (Ambystoma amblycephalum), a micro-endemic axolotl from Mexico scientifically confirmed only once since its original description in 1940, and now presumably extinct. In 2018, paedomorphic and metamorphosed adults, as well as clutches and larvae, were found in a cattle pond at Nahuatzen, Michoacán state, Mexico, ~60 km away from the type locality (Tacícuaro). Morphometric comparisons suggested high similarity with the type series of A. amblycephalum, while mitochondrial DNA barcoding (16S and control region) revealed close (but imperfect) matching to a reference sequence. We gathered data on life history and ecology of this population, which could be the only extant relic of A. amblycephalum. Its highly limited distribution and presumably low population density are hallmarks for a high risk of extinction, and alarms on the critical situation of many micro-endemic salamanders of Mexico, hence calling for immediate conservation actions.

The academic picture of a globalized European countryside, and particularly of rural areas in postsocialist, new member states of the European Union, is one of huge and increasing complexity, diversity, and uncertainties about the future. The aim of this research is to construct alternative scenarios for rural Croatia in 2030, acknowledging its postsocialist transition as an important framework. Future development scenarios were constructed by integrating quantitative and qualitative approaches. The main methods used were: factor and cluster analysis; Monte Carlo simulation; and Delphi method, involving 37 rural experts in two rounds of written questionnaires. Four scenarios were developed: Rural Renaissance, Shift, Road to Nowhere, and Growth without Development. These scenarios provide a set of well-documented and reasonable assumptions to aid in thinking about possible future paths for the Croatian countryside, while at the same time allowing for the discussion of rural development paradigms.

- Abstract
Aim: This study aimed to determine knowledge and attitudes toward induced pluripotent stem cell technology and biobanking. Methods: A survey instrument was developed to determine individuals' knowledge of and attitudes toward these technologies. Results: Results from 276 ethnically diverse participants who took the online survey demonstrated significant associations (p ≤ 0. 05) in knowledge by ethnicity and race regarding properties of stem cells, different types of stem cells and previous sample donation behavior. Significantly more Whites 39% (n = 53) compared with Blacks or African–Americans 19.2% (n = 14) had previous knowledge of induced pluripotent stem cells (χ
2 = 8.544; p = 0.003) Conclusion: Overall, White race was associated with greater knowledge about stem cells and biobanks and greater willingness to donate samples for future research. Stem cell biobanks have few samples from minorities for genomic studies. We conducted an online survey to understand knowledge and attitudes toward stem cell biobanks and technologies. Overall, we learned that White race was associated with the greatest knowledge about stem cell biobanks and willingness to contribute tissue samples for biobanks. More education is required so that minorities are willing to contribute tissue samples toward stem cell biobanks. This will help researchers study the genomic bases of disease and pursue translational research toward addressing health inequities. [ABSTRACT FROM AUTHOR]- Published

Little is known about distribution patterns of micrometazoan organisms at different spatial scales and the mechanisms driving these patterns across different environments. Here we explore the fine-scale structure of tardigrades in a high-elevation Polylepis forest in northern Ecuador. To investigate spatial patterns of tardigrade abundance, we collected samples from different bryophyte taxa (hosts) on the woodland floor. We identified some tardigrades to species, but most taxa were considered at the level of morphological operational taxonomic units. Tardigrade assemblages differed in composition between host taxa, with some tardigrade taxa associated more with certain hosts, which might relate to host architecture or chemistry. Tardigrade occupancy, richness and abundance varied considerably between samples, and we estimate that more than 50 samples are required to estimate tardigrade taxon richness in this forest habitat. Physical distance between samples was not related to similarity of composition, and it seems that fine-scale differences in environmental conditions (including the distribution of host bryophytes) is much more important in determining tardigrade composition. We conclude that standardised, comprehensive sampling of terrestrial tardigrades at fine scales is necessary before making broader comparisons at coarser geographical scales. Such sampling should account for the diversity of potential hosts, with sufficient replication to capture tardigrade diversity. [ABSTRACT FROM AUTHOR]

Livelihood strategies used by households and individuals in rural communities are shaped by human, natural, financial, social and physical capital resources that can be accessed. The ability to diversify livelihoods depends on asset portfolios and the economic shocks that rural households face. The main objective of this paper is to improve understanding of rural livelihood challenges in south-east Zimbabwe and how households in this area diversify livelihoods to cope with these challenges. A cluster analysis of 200 households surveyed in 2008 in the Chiredzi district identified five distinct livelihood strategies: (1) subsistence smallholders/ unskilled workers; (2) subsistence smallholders/nontimber forestry products (NTFPs) harvesters; (3) crop production and NTFPs extraction integrators; (4) commercial smallholders with regular off-farm employment; and (5) specialised commercial livestock producers. Multinomial logit model results showed that the level of education of the household head, value of physical assets, cattle numbers and income, remittances, NTFP income and economic shocks were the main determinants of these livelihood choices. There is also some evidence that those households that were statistically significantly affected by HIV/AIDS shock practised distresspush diversification by harvesting NTFPs. These results suggest that policymakers need to advise rural households on how to improve their risk management capacities, and move from geographically untargeted investments in livelihood assets to a more integrated approach adapted to the asset bases of individual households.

A significant challenge that faces any teacher of introductory programming is the diversity of the class. At one extreme there will be students who have never programmed before, while at the other there will be students who have many years experience of programming. Handling this diversity is difficult. The temptation for the instructor is often to focus on the novice group and to assume that the others will get by with minimal supervision. This is understandable, but it can be risky. There is a very real risk that the neglected group of experienced programmers become bored and disengage from the course. At the worst, they can lose motivation and fail or drop out altogether. This paper describes and presents the outcomes of a project aimed at challenging the more experienced programmers in four introductory programming classes at four different UK institutions. The project took the form of a competition in which students were asked to devise and solve a series of programming challenges. [ABSTRACT FROM AUTHOR]

This study examined the earthworm community in permanent pastures at three self-contained farmlets that make up the long-term P fertiliser and sheep grazing study located at Ballantrae Hill Country Research Station. Thirty five years after the study was established, earthworm abundance was lower at the farmlet receiving no fertiliser since 1979 (LFNF, 219 m
−2 ), compared to that receiving 125 kg SSP/ha/year (LFLF, 384 m−2 ) or 375 kg SSP/ha/year (HFHF, 428 m−2 ). Earthworm species diversity increased from two in 1979, to nine in 2014, as a result of both accidental and deliberate anthropogenic earthworm introductions. Across all farmlets earthworm abundance was closely associated with pasture production, as well as several pasture attributes and soil variables, particularly those influenced by slope. Maximising the contribution of soil fauna to soil function in hill country requires recognising the influence of slope on earthworm habitats and associated resource availability.

Turfgrass lawns demand high inputs of nitrogen (N) to maintain attractive and functional landscapes. Endophytic diazotrophs have a high potential to increase N in the host plant and promote growth by biological N fixation. The aim of this study was to identify the genetic diversity of culturable putative diazotrophs associated with seashore paspalum (Paspalum vaginatum Swartz) cultivars in southern China. A total of 78 isolates were collected from the roots, stems and leaves of healthy plants. A phylogenetic analysis showed that all the isolates were classified into 10 species from nine genera. The dominant genera were Bacillus, followed by Curtobacterium and Stenotrophomonas. The population of diazotrophs in the roots was more diverse than that in the stems and leaves. The 10 representative strains were found to be positive for nitrogenase activity and amplification of the nifH gene, and nine strains could solubilise inorganic phosphate. In addition, two isolates of bacteria, Bacillus pumilus and Lysinibacillus macrolides, were selected to evaluate the promotion of plant growth by inoculation. Ryegrass and rice plants inoculated with bacteria displayed significantly greater root and shoot biomass than un-inoculated plants. It is crucial to further explore their potential roles in the biology of these plants. [ABSTRACT FROM AUTHOR]

NUMBERS of species - Abstract
Our goal is to estimate the true number of classes in a population, called the species richness. We consider the case where multiple frequency count tables have been collected from a homogeneous population and investigate a penalized maximum likelihood estimator under a negative binomial model. Because high probabilities of unobserved classes increase the variance of species richness estimates, our method penalizes the probability of a class being unobserved. Tuning the penalization parameter is challenging because the true species richness is never known, and so we propose and validate four novel methods for tuning the penalization parameter. We illustrate and contrast the performance of the proposed methods by estimating the strain-level microbial diversity of Lake Champlain over three consecutive years, and global human host-associated species-level microbial richness.

This study examined the diversity, distribution and abundance of fish species in Upper Awash River, Ethiopia was assessed. Five sampling sites were selected along the gradient of the river. Fish sampling was carried out using Frame net of 3-mm stretched mesh size from February through April, 2018. There was a considerable variation in river depth and width at all sites. A total of 3018 fish categorized under three species belonging to the Family Cyprinidae, namely, Garra quadrimaculata, Garra dembeensis and Labeobarbus beso were identified. Garra quadrimaculata was numerically the most dominant species in all sampling sites. Perhaps, there was no fish specimen caught from S-I. Similarly, the highest and lowest number of G. dembeensis was collected from S-V (42.73%) and S-II (2.51%), respectively. The composition of L. beso was higher at S-IV (49.1%), but no L. beso collected from S-I and S-II. High number of fish was caught from the pool parts at all sites. Shannon diversity index (H') varied between 0.14 and 0.80, and evenness index (J') varied from 0.2 to 1.7, but H' and J' of S-I were zero due to the absence of species in the area. Based on Shannon index, the upper Awash River was categorized as an impacted river. Therefore, effective management of the river is very imperative for sustainable utilization of fish resources.

What can one say to the self-deceived? And – perhaps more importantly – who can say it? The attribution of self-deception depends heavily on the criteria for what is thought to be beyond dispute. For Galeotti, misperception of reality is a product of psychological and emotional pressure resulting in 'emotionally overloaded wishes', and her solution thus involves the construction of what an 'impartial' and 'dispassionate' observer would conclude when presented with the same evidence. Drawing on her examples of foreign policy decision-making, I discuss two objections. First, I ask whether being 'dispassionate' is enough get one off the hook from the sorts of value judgements that must be made in assessing evidence in complex situations. Second, I address the role of disagreement and dissent, and suggest that what is required are not actors with a lack of emotionally overloaded wishes, but actors with different goals and wishes. Thus, while Galeotti emphasizes solutions drawing on ideals of impartiality, we might more productively look for solutions that engage multiple forms of partiality. [ABSTRACT FROM AUTHOR]

African termites are classified into five distinct families, Termitidae, Rhinotermitidae, Hodotermitidae, Termopsidae and Kalotermitidae. Termites are undoubtedly one of the key ecosystem engineers. Because they harbour more nutritive plants, herbivory by large herbivores is biased towards mounds. Their engineering role is visible through construction of conspicuous termite mounds, which often harbour some unique species compared with the expansive ecosystem in which they occur. To understand the cascading effects of termite mounds on ecosystem functioning, we present a review on how termites create ecosystem heterogeneity, and how this heterogeneity in terms of soil physical and chemical characteristics, particularly nutrients, further influences vegetation production, diversity and palatability to large herbivores. Here we review literature mainly focusing on: (i) Phylogeny (evolutionary history) of African termites, (ii) mound construction, (iii) mound spatial distribution, (iv) termite foraging (v) termite nutrient cycling, (vi) termite influence on hydrology, (vii) termite mound influence on plant species diversity and (viii) termite mound influence on large herbivores. Our review showed that African termites are diverse, with the potential to influence ecosystems heterogeneity through soil nutrients enrichment, which in turn influences forage abundance (thicket clumps), diversity and quality. High forage quality occurring on termite mounds influences herbivory patterns in the savanna ecosystem. Herbivory is reported to be higher on termite mounds compared to the expansive savanna landscape. The most common plant family occurring on termite mounds is Capparaceae. We suggest that future studies focus more on: (1) the influence of termite mounds on plant functional traits, (2) the importance of termite mounds in dryland savanna cropping/rangeland systems, and (3) on ways to support establishment of mound building termite species.

Biostatisticians with advanced degrees are highly sought after. Employment opportunities in the fields of mathematics and statistics are expected to increase dramatically by 2028. Underrepresentation of minorities in biostatistics has been a persistent problem, yielding a demographic landscape that differs substantially from the general U.S. population. In some instances, students may have the appropriate quantitative skills, but are unaware of biostatistics and in other instances, students may not yet have the appropriate quantitative background, but are intellectually capable and willing to shore up those skills once they learn about biostatistics as a viable, exciting career option. Therefore, to ensure robust scientific advancement, there must be a concerted effort to increase the pipeline of intellectually talented persons available with exposure to the appropriate quantitative skills who are interested in careers in biostatistics. The overarching goal of this article is to discuss the development, implementation, and impact of a federally funded pipeline initiative aimed at increasing the number of underrepresented minorities successful in graduate training and professional careers in biostatistics as well as establishing effective mentoring and networking relationships. Our findings provide a roadmap for the development of sustainable initiatives to promote diversity in biostatistics and science, technology, engineering, and mathematics fields more broadly. Supplementary files for this article are available online. [ABSTRACT FROM AUTHOR]

Pselaphotumulus Owens and Carlton, gen. nov., is described as the sixth genus in the tribe Pselaphini known from New Zealand. Three new species are described: Pselaphotumulus aorerei, sp. nov., Pselaphotumulus dubius, sp. nov. and Pselaphotumulus unus, sp. nov.. Three species, Pselaphus cavelli (Broun 1893), Pselaphus oviceps (Broun 1917) and Pselaphus urquharti (Broun 1917) are transferred to Pselaphotumulus, nov. combs. Lectotypes from type series in the New Zealand Broun Collection (Natural History Museum, London) are designated for these three species. Habitus photographs, distributional maps and line drawings of diagnostic characters are provided for each species. A key to species is provided. Searches of museum collections have not yielded representatives outside of New Zealand, suggesting that this is the first endemic genus in the tribe Pselaphini described from the New Zealand's main islands, specifically, the South Island. Pselaphotumulus species exhibit restricted distribution patterns that approximately coincide with the Pacific/Indo Australian Plate boundary. [ABSTRACT FROM AUTHOR]

Background: In order to offer all students the opportunity to progress and grow to their full potential, teachers must positively recognise and value the different expressions of diversity of all the class members. One of the biggest educational challenges that teachers face today is how to address classroom practices from a truly inclusive and democratic perspective. Purpose: The main aim of this study was to explore, in a Spanish context, how primary school teachers articulate and implement inclusive and democratic practices in their classrooms. Design, sample and methods: The methodological design of this study was situated within a qualitative research approach. A multiple case study structure, comprising three case studies, was utilised. Data collection was carried out via interviews, classroom practices inventories, scientific observation and analysis of documentation. The study was carried out over three academic years and had three phases. Data were analysed thematically. Findings: In the three cases analysed, the analysis identified different possibilities in terms of the implementation and articulation of pedagogical differentiation (the structures, content, process and product) and democratic classroom management (collaborative culture, a shared leadership, democratic participation and school linked to environs). Conclusions: The analysis highlights the need to support the formation of a critical citizenship within inclusive contexts, as well as the need to develop a sense of belonging to the educational community.

Background: The international body of research on student voice concludes that active pupil participation has multiple positive effects on the work environment and learning for pupils. In a large study on gender equality and diversity work in Swedish schools, it became evident that pupils wanted to be active participants. However, pupils considered that their wishes were, to a large extent, ignored. Therefore, it is important to try to understand this further by investigating pupils' perceptions of their experiences. Purpose: The purpose of the study was to explore how discourses of participation and power are practised, not practised, and materialised, by focusing in-depth on pupils' representations of gender equality and diversity work within a small sample of Swedish schools. Methodology: The study is based on data from 10 focus group interviews with 43 pupils from 4 different schools, 2 compulsory schools (pupil ages 6–15) and 2 upper secondary schools (pupil ages 16–18), in Sweden. The thematic analysis utilised a gender perspective anchored in a critical policy analysis approach. Analysis and Findings: The analysis of focus group data identified three pupil representations of gender equality and diversity work: a onetime occurrence, longing for participation and the (un)fair teacher. These representations were derived from and intertwined with discourses on pupil participation and power. Three sub-discourses were found within the discourse on participation and power: normative barriers to participation, structural barriers to participation and openings in the barriers to participation. The first two sub-discourses support the maintenance of unequal power relations between adults and pupils, while the third challenges these power relations. Conclusions: Our study suggests that no substantial levels of participation or power among the pupils were represented at the schools. Instead, the analysis visualises pupils as expressing powerlessness and disengagement. However, the discourse Openings in the barriers to participation, together with pupils' democratic abilities, has the potential to enable change and the development of pupil participation in schools.
