ІNCLUSION IN HIGHER EDUCATION: PHILOSOPHICAL AND SOCIAL CONTEXT

The article analyses the problem of implementing inclusion in higher education in various developed countries. The author reviews the main international declarative and legal documents that form the basis for the implementation of the principles of inclusion in society in general and in the educational sector in particular. The author traces the connection between changes in public consciousness and activities of higher education institutions in the respective countries with regard to the adoption of the principles of equality and inclusion. It has been found that the implementation of the principles of inclusion in higher education is possible in societies with a high level of community well-being, as evidenced by the higher education systems of highly developed countries that are at the forefront of promoting inclusive university education. That is, inclusive practice in higher education, which is not a compulsory educational level, is developing thanks to social activism and support from government institutions. In fact, the task of the university is to provide a favourable inclusive educational space for a student with special needs. The author draws attention to the fact that promoting an inclusive form of education in a higher education institution should not impair the quality of educational services and limit the level of professional competencies acquired by a person with special needs. The author identifies the key problem of inclusion in higher education - achieving stability in its provision. The author believes that this stability can be achieved through the implementation of the following steps: equal admission of an applicant with special needs; effective training in an inclusive educational space with the acquisition of a full set of professional competencies and the ability to implement the acquired professional elements in professional activities. In the author's opinion, the current progress on the part of Ukrainian society has received a peculiar vector sequence: formation of an understanding of the demand for higher education for people with special needs; search for effective and efficient inclusive formats for organising the educational process in a higher education institution; creation of a unified and universal system of inclusive higher education, which will be integrated into the local educational strategies of a particular higher education institution. This algorithm harmonises the aspirations and wishes of a person with special needs and the capabilities and transformations of the university.

Gender, number and person: a three-way interaction

Abstract According to the principle of informativity, more useful information is more likely to be coded than less useful information. This principle underlies Greenberg’s Universals 37 and 45, which state that a larger number of (sex-based) gender contrasts are on average found in singular than in non-singular forms. As an increase in group size lowers the probability of same sex groups, gender-specific personal pronouns are less useful in the non-singular than in the singular. Curiously enough, the principle of informativity also makes the opposite prediction: in the first person, non-singular forms are predicted to show a gender contrast more frequently than singular forms do. Moreover, exclusive forms are predicted to develop gender distinctions more often than inclusive forms. In this paper, these predictions are put to a typological test. A total of 51 languages from 17 different families and 24 different genera has been found in which the first person singular personal pronoun is gender-neutral while one or more of its non-singular counterparts inflect for gender. It is argued that Universals 37 and 45, as well as their counterclaim, are empirically adequate. This apparent paradox dissolves in a three-way interaction of gender, number and person in pronominal paradigms. In keeping with the principle of informativity, there is a bias in favour of gender marking in the third person singular but also a bias in favour of gender marking in the first person non-singular.

Role of Longitudinal Temperature Gradients in Eliminating Interleaving Inclusions in Casting of Monocrystalline Silicon Ingots

Infrared analysis reveals the presence of interwoven inclusions, primarily comprised of silicon nitride and silicon carbide, in the casting process of monocrystalline silicon ingots. This study investigates how the longitudinal temperature gradient affects the removal of inclusions during the casting of monocrystalline silicon ingots through simulations and comparative experiments. Two monocrystalline silicon ingots were cast, each using different longitudinal temperature gradients: one employing smaller gradients and the other conventional gradients. CGSim (Version Basic CGSim 23.1) simulation software was utilized to analyze the melt flow and temperature distribution during the growth process of quasi–monocrystalline silicon ingots. The findings indicate that smaller longitudinal temperature gradients lead to a more robust upward flow of molten silicon at the solid–liquid interface, effectively carrying impurities away from this interface and preventing their inclusion formation. Analysis of experimental photoluminescence and IR results reveals that although inclusions may not be observed, impurities persist but are gradually displaced to the top of the silicon melt through a stable growth process.

Rapid classification of a novel ALS-causing I149S variant in superoxide dismutase-1

Variants of the oxygen free radical scavenging enzyme superoxide dismutase-1 (SOD1) are associated with the neurodegenerative disease amyotrophic lateral sclerosis (ALS). These variants occur in roughly 20% of familial ALS cases, and 1% of sporadic ALS cases. Here, we identified a novel SOD1 variant in a patient in their 50s who presented with movement deficiencies and neuropsychiatric features. The variant was heterozygous and resulted in the isoleucine at position 149 being substituted with a serine (I149S). In silico analysis predicted the variant to be destabilizing to the SOD1 protein structure. Expression of the SOD1I149S variant with a C-terminal EGFP tag in neuronal-like NSC-34 cells resulted in extensive inclusion formation and reduced cell viability. Immunoblotting revealed that the intramolecular disulphide between Cys57 and Cys146 was fully reduced for SOD1I149S. Furthermore, SOD1I149S was highly susceptible to proteolytic digestion, suggesting a large degree of instability to the protein fold. Finally, fluorescence correlation spectroscopy and native-PAGE of cell lysates showed that SOD1I149S was monomeric in solution in comparison to the dimeric SOD1WT. This experimental data was obtained within 3 months and resulted in the rapid re-classification of the variant from a variant of unknown significance (VUS) to a clinically actionable likely pathogenic variant.

When Your Pronominal Marking Matters during a Pandemic: Shawi Pronominals and COVID-19 Interventions

In this communication, I focus on Shawi forms of address used in Peruvian State posters during the COVID-19 pandemic. The COVID-19 pandemic took a heavy toll on the Peruvian Indigenous population. A recent study showed that Indigenous people had 3.18 times the risk of infection and 0.4 times the mortality risk of the general population in Peru. The Shawi have not been included among the most heavily affected. A preliminary descriptive and critical account of Peruvian State posters whereby languages such as Shawi and other Peruvian Indigenous languages (Awajun, Ashaninka, different varieties of Quechua, Shipibo, etc.) have been used to prevent the spread of COVID-19 is provided. Shawi seems to be the only language of the sample where information has been framed using first-person inclusive forms. This appears to have led to enhanced communal engagement in the suggested health-related practices. Additionally, opinions on the issue from local stakeholders are briefly discussed. While the results are derived solely from preliminary observations, my findings could serve as a basis for enhancing health communication strategies in other Indigenous contexts, utilizing linguistically informed intercultural approaches.

Study on the metallurgical mechanisms of inclusions in the FGH4096 alloy during electron beam smelting

In this study, the metallurgical mechanisms of inclusions during electron beam smelting (EBS) of a FGH4096 powder superalloy was investigated. The macroscopic morphology of the ingots, as well as the composition and structure of inclusions were studied. The effect of electron beam smelting parameters on the cooling rate, O/N content, number density and size of inclusions have been revealed. Besides, the mechanisms for inclusions removal and formation were elucidated. The results show that inclusions in the final solidification zone are mainly oxides (simple tetragonal CrO2, hexagonal Al2O3, and face-centered cube TiN), whereas the complex inclusions and carbon nitrides with Al2O3 and TiN as the nucleation cores are mainly present in the matrix. With the increase in smelting power and time, both the cooling rate and O/N content decsrease, and the smelting power shows a greater impact on the cooling rate. The number density of total inclusions increases with the increase in the smelting power. As the smelting time increases, the number density of total inclusions decreases, while the size of complex inclusions and carbon nitrides increases. This is attributed to the combined effect of cooling rate and O/N concentration in the alloy under different smelting parameters. Thermodynamic calculations indicate that Al2O3 forms in the solid-liquid phase region. The precipitation of TiN occurs when the alloy solidifies, and its precipitation temperature is higher than that of TiC. The lattice mismatch between Al2O3 and TiN is 8.14%, while that between TiC and TiN is 6.94%, which effectively promotes the heterogeneous nucleation of complex inclusions and carbon nitrides. The formation mechanisms of complex inclusions and carbon nitrides provide a theoretical basis for purification of superalloys by electron beam metallurgy.

МОДЕЛІ «ДЕРЖАВИ ЗАГАЛЬНОГО ДОБРОБУТУ» ТА ЇХНІ ХАРАКТЕРИСТИКИ

The article examines the peculiarities of the welfare state model, which has been constantly changing, transforming, having different options for implementation, going through a crisis and post-crisis development. It is determined that only the state, in the policy of the welfare state, acts as a guarantor of social rights and opportunities for its citizens. The author reveals the types of welfare models and their main characteristics that determine the peculiarities of social policy implemented by countries. It is established that the model of the “welfare state” has experienced an economic, ideological and philosophical crisis, which has led to the need to update and modernize the conceptual foundations of its implementation. The author proves that changes in the country’s social policy allow for a clear distinction between programmatic retrenchment and systematic retrenchment, i.e., reduction of social programs or reduction of social expenditure financing in the welfare state model. The author reveals the typology of models of management of the state social policy, in particular: pluralistic, corporate, Marxist and elite models. It is proved that the main social task of the state’s economic policy is “not to distribute benefits, but to ensure the conditions of freedom and independence of individuals who are able to create these benefits and take care of themselves and their families on their own”. The modern version of the socio-economic model of the “welfare state” is to create conditions that will ensure the synergy of market self-regulation and state intervention, and can be implemented in the areas of economic freedom and personal development. In addition, the areas of development of the welfare state are: risks and innovations, social solidarity, social justice, lifelong support, distribution of difficulties between generations, which is part of the concept of sustainable development. It is established that the transformation of the welfare state model leads to a change in the mechanisms and instruments for its implementation, in particular: universalization of social expenditures; policy coherence between social, economic and environmental aspects of development; search for inclusive forms of its implementation and partnership between the State, civil society and business; identification of new directions in global and regional social policy. It is established that the choice of implementing the “welfare state” model depends on the historical, socio-cultural and economic conditions prevailing in a country and is determined by the type of its socio-political system, ideological and spiritual principles, and the peculiarities of the stage of development. Key words: welfare, state, models of the welfare state, social justice, social security.

Improvements in the Quantification of End-Member Vapor Compositions in Fluid Inclusion Boiling Assemblages and Implications for Metal Transport by Low-Density Fluids

Abstract Under conditions typically found in the Earth’s crust, there is a large pressure-temperature-composition range in the H2O-NaCl system where fluids may separate into a low-salinity vapor end member and a high-salinity liquid end member. However, heterogeneous trapping is common during the formation of fluid inclusions in an immiscible fluid system, violating the fundamental assumption of homogeneous entrapment for fluid inclusion microthermometry. This has profound consequences on the composition of these fluid phases and consequently on the formation of ore deposits from hydrothermal systems. At the same time, minor mixture of the high-salinity liquid phase with the low-salinity vapor phase cannot be distinguished from the end-member vapor-rich fluid inclusions by their bubble sizes. Precise determination of the salinities of vapor-rich fluid inclusions using microthermometry is deterred by the very small proportion of the liquid phase and the limitation of the analytical precision. All this will lead to erroneous compositional data from fluid inclusion analysis. We have quantitively calculated the variations of fluid inclusion properties caused by heterogeneous entrapment during phase separation in the H2O-NaCl system and showed that the salinity, and thereby the element contents and element/Na ratios of the vapor-rich fluid inclusions, is significantly changed in heterogeneously trapped fluid inclusions. The addition of 1 vol % of the high-salinity end member to the low-salinity end member results in a salinity change from 0.99 to 4.4 wt % NaCl equiv at the phase separation condition of 800 bar and 750°C. This will have a significant impact when it comes to determining the concentration of elements transported as chlorine complexes and typically leads to an overestimation of the mass transport capability by the vapor phase. Therefore, every effort should be taken during microthermometry to find and measure the least affected vapor-rich fluid inclusions. Our numerical calculations and synthetic fluid inclusions reveal that there is a linear relationship between the salinity and element contents for fluid inclusions at different extents of heterogeneous entrapment. Therefore, linear correction to the measured lowest vapor salinity can obtain a good approximation of the element contents in the end-member vapor phase.

Agglomeration behaviors of different types of complex TiN inclusions in high titanium wear resistant steel

Large-sized titanium-containing inclusion clusters seriously affect the continuous casting and performance of high titanium wear-resistant steel. In the current work, thermodynamic calculations were firstly conducted to predict the formation of various complex TiN inclusions, viz, TiOx-TiN, Al2O3–TiN and LaAlO3–TiN. Based on that, laboratory-scale experiments were designed to prepare samples containing a single type of complex TiN inclusions. The agglomeration characterizes of different complex inclusions were compared by combing in-situ observation based on confocal laser scanning microscopy and Newtonian motion equation. Furthermore, the Kralchevsky-Paunov model was used to study the influences of density and size on the agglomeration behavior of complex TiN inclusions. The result shows that the attractive force between TiOx-TiN complex inclusions increases from 1.93 × 10−18 to 4.34 × 10−17 N, while it was 3.41 × 10−17 to 5.12 × 10−16 N for Al2O3–TiN complex inclusions and 6.42 × 10−18 to 1.14 × 10−16 N for LaAlO3–TiN inclusions. Based on the experimental results and theoretical calculation, the agglomeration tendency of Al2O3–TiN is the strongest due to the considered size and compared to the TiOx-TiN inclusions, the stronger agglomeration tendency of LaAlO3–TiN ones can be attributed to their higher density.

The Effect of Rare Earth Y on the Inhibitor Precipitation Behavior of Strip‐Cast Grain‐Oriented Silicon Steel

0.3 mm‐thick grain‐oriented silicon steel sheets with varying Y contents are produced via twin‐roll strip‐casting and two‐stage cold rolling process. This study primarily investigates the evolution of microstructure, texture, and precipitation along the processing. Specifically, the effect of rare earth Y on second‐phase particle precipitation in ultralow carbon grain‐oriented silicon steel is examined. Results indicate that higher Y content will consume beneficial inhibitor elements such as S and N, leading to the formation of coarse rare earth inclusions (≈10 μm) in the cast strip. This significantly diminishes inhibition ability and magnetic induction (B8 = 1.58 T≈1.71 T). On the contrary, the addition of trace Y can accelerate the precipitation of inhibitors. During the intermediate annealing stage, steel with trace Y exhibits a significant enhancement in precipitate distribution density (from 2.8 μm−2 to 13.6 μm−2), and the final magnetic induction B8 increases from 1.86 T to 1.91 T compared to steel without Y. In addition, the results of first‐principle calculations based on density functional theory reveal that the doped Y atom prefers to segregate at the Al–N interface, and the interface energy reduces from 1.871 J m−2 to 1.024 J m−2, thereby promoting the precipitation of AlN.

Genesis of Cu-Sn Mineralization in the Shuangjianzishan Super-Large Silver Deposit, Inner Mongolia: Trace Element Constraints from Chalcopyrite and Cassiterite

The Shuangjianzishan silver polymetallic deposit is located in the copper–tin–lead–zinc–silver polymetallic metallogenic belt in the Southern Great Xing’an Range, with silver resources of more than 18,000 t, which is the largest silver polymetallic deposit in Asia. Early studies concluded that the Shuangjianzishan deposit is typically an epithermal Ag-Pb-Zn deposit that lacks a high-temperature mineralization stage. In recent years, with the deepening of research, a large amount of Cu-Sn mineralization has been found in the deep part of the Shuangjianzishan deposit, but it is less studied. The laser-ablation inductively coupled mass spectroscopy (LA-ICP-MS) technique is used to investigate the distribution and substitution of trace elements in chalcopyrite and cassiterite. In this paper, the trace element study of chalcopyrite and cassiterite from the Shuangjianzishan deposit reveals that Sn, In, As, Se, Sb, and Tl mainly exist in chalcopyrite in isomorphic form, while Pb, Bi, and Ni mainly exist in chalcopyrite in the form of mineral inclusions. The enrichment of the high-temperature elements Sn and Se in chalcopyrite, and the deficit of the middle- and low-temperature elements Ga, Sb, etc., reflect that the chalcopyrite in the Shuangjianzishan deposit was formed in a middle- and high-temperature environment, and it also indicates that the early ore-forming hydrothermal solution may be rich in Sn. Fe, In, Co, and Ni mainly exist in cassiterite in isomorphic form, and the content of W in cassiterite is high. There are two main forms, one is isomorphic and the other is wolframite inclusion. Cassiterite has Fe-rich and W-U-poor characteristics, indicating that cassiterite from the Shuangjianzishan deposit was formed under relatively oxidized conditions, and the relative enrichment of elements such as Fe, W, Zr, and Hf indicates that the temperature of cassiterite formation was high. The elemental content and inter-ionic coupling relationships suggest that the cassiterite from the Shuangjianzishan deposit may have an elemental replacement mechanism of W6+ + Fe2+ ↔ 2Sn4+ or Fe3+ + OH− ↔ Sn4+ + O2−. The trace elements in cassiterite of the Shuangjianzishan deposit are rich in Fe and Mn and depleted in Nb and Ta, according to the Fe-W diagram, and the tin mineralization of the Shuangjianzishan deposit belongs to cassiterite–sulfide-type tin mineralization. Chalcopyrite Co/Ni ratios >1 are consistent with the characteristics of chalcopyrite genesis in hydrothermal deposits.

Optimal operating conditions for the rapid growth of KH2PO4 crystal by numerical simulation

Numerical simulations of the turbulent hydrodynamics and concentration in the rapid growth of potassium dihydrogen phosphate (KH2PO4 or KDP) crystals have been performed. In this work, a quadratic power-law growth model is applied, concerning the mass transfer occurring at the crystal surface during the growth process under low supersaturations. The mass transfer boundary condition is discretized by using the Over-Relaxed approach. The effects of the growth temperature and rotation rate on surface supersaturation distribution and the diffusion layer are investigated, which are critically involved in the processes of surface morphological instability and inclusion formation. Due to the kinetic limitation, the response of different types of crystal surfaces to temperature varies, with a pyramidal surface about twice as high as a prismatic face. In addition, the contour map of the growth rate combined with the coefficient of variation (C.V) for various temperatures and rotation rates is used. Uniformity of surface supersaturation is provided by lowering the growth temperature and increasing the rotation rate. Furthermore, the criteria of crystal growth strategies are proposed to optimize the process parameters and obtain favorable conditions for crystal growth, thereby facilitating defect-free and high-quality crystal formation at an appropriate growth rate.

“It’s difficult, but it’s worth it”: Saudi Mothers’ investment in their children’s Arabic heritage learning in the U.S.

ABSTRACT This case study delves into the experiences of three Saudi mothers living in the United States, exploring their evolving understanding of their children’s language needs and the obstacles they face as learners of Arabic heritage language (AHL). The study is rooted in the notion of language as a form of capital and Bonny Norton’s metaphor of investment in language learning. It examines how AHL serves as a multifaceted form of social, cultural, and academic capital for their children’s present and future lives in both the U.S. and Saudi Arabia. Through individual, semi-structured interviews, the study unveils the experiences, motivations, and challenges faced by the mothers in maintaining their children’s AHL. The findings illustrate three distinct stages in the children’s language learning journey, initially emphasizing English as the predominant language with capital in the U.S. followed by a crucial shift toward recognizing the significance of AHL preservation. Ultimately, this study sheds light on the nuanced role of AHL as an essential asset and its interconnectedness as a dynamic cultural and academic resource. The implications extend to social inclusion and identity formation, enriching our understanding of the intricate interplay between language, culture, and identity development.

Towards Inclusive Futures for Worker Wellbeing

The global COVID-19 pandemic has spurred on new collaborations across borders, and emphasized the importance of supporting wellbeing in the workplace, whether that workplace is hybrid, remote, or in-person. Work in CSCW, HCI, and organizational psychology has explored how people come to understand their wellbeing at work, and the role of identity, culture, and organizational factors in that process. In this study, we build on this past research and explore the importance of these factors when designing tools that support worker wellbeing for location-independent teams. We ask the question: how did organizational, cultural, and individual factors influence how workers understood their workplace wellbeing needs during the move to remote work? To investigate this question, we conduct a large scale linguistic analysis of 13,265 diary entries collected between 2020 - 2022, and complement it with in-depth interviews with 26 global employees, exploring intersections between technology, context, and wellbeing needs. We utilize this data to analyze the broader human infrastructure supporting hybrid and remote work, demonstrating how ideas around wellbeing are influenced by the (often technology-mediated) environment around both information and essential workers, and power differentials within it. Building on our findings, we provide recommendations for how technology design can better support more diverse and inclusive forms of worker wellbeing.

Awareness of Financial Inclusion: An Empirical Study in Tiruttani Taluk, Thiruvallur District, Tamil Nadu.

The Indian government consistently makes efforts to include rural people in the organized financial system. This initiative not only boosts the Indian economy by encouragement of savings habit, but also facilitates rural development through access to banking facilities, services like gas subsidies etc. The term “financial inclusion” may vary under different ruling parties, but the primary objective remains consistent: to uplift the bottom of the financial market pyramid. The current state of affairs indicates that the present government has achieved some success by opening approximately 12.54 crore new bank accounts (as of January 2015) and accumulating deposits of over Rs. 5000 crore (up to November 2014) through the Pradhan Mantri Jan Dhan Yojana (PMJDY), a new form of financial inclusion. However, it is evident that a significant portion of the rural market remains untapped and under-explored. Therefore, this paper aims to explore the awareness of financial inclusion schemes among rural customers in Tiruvallur District, Tamil Nadu. The study seeks to understand how effectively these initiatives are reaching the intended beneficiaries and identify areas for improvement. By enhancing awareness and accessibility, we can further empower rural communities and promote inclusive economic growth.

Comprehensive ultrasound assessment of the state complex intima-media brachiocephalic arteries in patients with metabolic syndrome

Objective. Comprehensive ultrasound assessment of the state complex intima-media (CIM) of brachiocephalic arteries in patients with metabolic syndrome (MS). Materials and methods. 82 patients were examined, including 62 patients with MS and 20 practically healthy individuals. All patients underwent biochemical blood analysis, ultrasound of the extracranial sections of the brachiocephalic arteries with an assessment of the qualitative and quantitative characteristics of CIM bifurcation of the brachiocephalic trunk (BCT), common carotid arteries (CCA) and vertebral arteries (VA).Results. 100% of patients with MS, changes in the echostructure of CIM were recorded in the form of pathological layering, 9 (14.5%) patients – in the form of hyperechogenic inclusions. Thickness of CIM in the bifurcation of BCT and CCA in patients with MS statistically significantly exceeds the same indicator in practically healthy persons and demonstrates direct correlation between the components of MS. The modified Carnegan index patients with MS is statistically significantly higher than the same indicator in practically healthy individuals and demonstrates direct correlation with the thickness of CIM estimated in different segments of the brachiocephalic arteries (BCT k 0.356, RCCA k 0.718, LCCA k 0.846, in the bifurcation of CCA on the right k 0.431, on the left k 0.519).Conclusion. Comprehensive ultrasound assessment of the state brachiocephalic arteries in patients with MS allows us to obtain complex of qualitative and quantitative signs characteristic of metabolic angiopathy.

A review of the institutional landscape for dual-career hiring in higher education

Meeting the needs of dual-career academic couples has become an important part of university efforts to foster family-friendly workplaces. Many universities have developed formal or informal approaches to addressing dual-career issues, but variation across institutions has made it difficult to detect wider patterns or probe their implications. In this paper, we analyze the dual-career policies and materials (848 documents total) of all R1 institutions in the United States. As with studies from roughly two decades ago, we find deficiencies in institutional support and transparency. However, given reduced state revenues for institutions of higher education and a rise in precarious employment arrangements over the same time period, conditions for academic couples are arguably worse today. In order for universities to address these concerns and contribute meaningfully to broader forms of inclusion, we argue that there is a need for sustained funding commitments and infrastructural support for dual-career programs.

Contribution of Culture-loaded Loanwords to the Class of Etymological Doublets in the Contemporary English Language

The article examines the loanwords from the autochthonous languages of South Asia and (or) regional variants of English into the Inner Circle English (according to Br. Kachru) – ayah, baboo / babu, baksheesh, feringhee / feringhi / ferinji / firanghi, gooroo / guru, maharaja / maharajah, maharani, maharishi, mahatma, mandarin, mantra, pagoda – and their role in expanding doublet pairs in contemporary English. The topicality of the study is due to the replenishment of the class of etymological doublets as a result of extensive borrowing process from the languages of the postcolonial space into pluricentric English due to increased population mobility, dispatriation, growing bilingualism, and expansion of global contacts. The scientific novelty is explained by the insufficiently studied subject of the research – the distinctive features of new doublets (native word vs. loanword, loanword vs. loanword) and the dynamics of their usage in contemporary English. The continuous sampling, statistical, descriptive methods are used in order to determine the role of culture-loaded loanwords in expansion of rows of etymological doublets. The major conclusions of the conducted research can be summed up as follows. The conditions for the formation of etymological doublets can be classified into mandatory (etymological similarity, i.e. relation to the same etymon: *awo-; *bhag-; *gwere-; *meg-; *men-; *pəter-; *preg-, *pregn-; *ten-;) and additional (acceptable graphical, phonetic, morphological variation and semantic identity). The study of empirical material allows us to identify trends towards, firstly, maximum divergence of the components of etymological doublet pairs and, secondly, increased frequency of culture-loaded loanwords due to the development of polysemy, strengthening of word-formation potential, formation of syntagmatic connections and inclusion in paradigmatic relations. Using the example of etymological doublets, one can trace the formal (mainly phonetic) and functional (mainly semantic) evolution of prototype words in donor languages.

Deciphering Clues Regarding Magma Composition Encoded in Quartz‐Hosted Embayments and Melt Inclusions Through Direct Numerical Simulations

AbstractCrystal‐hosted melt embayments and melt inclusions partially record magmatic processes at depth, but it is not always obvious how to interpret this record. One impediment is our incomplete understanding of how embayments and melt inclusions form. In this study, we investigate the formation mechanism of embayments and melt inclusions during quartz growth to quantify the relationship between the compositions of the entrapped and average melt. We study the growth of embayments and inclusions through direct numerical simulations that couple the growth of a crystal surface with the evolution of the concentrations of incompatible components in the surrounding melt. We find that H2O is more enriched in the interior of defects on crystal surface compared to the exterior. The resultant lower disequilibrium in the defect interior causes lower growth rate than in the exterior, elongating the defect into an embayment. If crystal growth stops, the composition in the embayment equilibrates with the average melt within days to months. If crystal growth continues until the embayment neck closes, a melt inclusion forms. The melt entrapped by both embayments and melt inclusions is enriched in incompatible components, such as H2O and CO2. In addition to inclusion size, the enrichment of incompatible components in melt inclusions also depends on component diffusivity and the crystal growth regime. High‐diffusivity components like H2O have similar enrichment levels in all scenarios, while lower‐diffusivity components like CO2 are more enriched in melt inclusions with smaller sizes or formed in continuous crystal growth.

Equity, Diversity and Inclusion: Class Inequalities within the British Documentary Film Industry

While there is a considerable amount of scholarship and grey literature about social exclusions within the UK cultural industries, the sociology of cultural labour has paid little attention to documentary film-making as a relatively elitist occupation that is maintained by systemic inequalities. Based on semi-structured interviews with several independent documentary film-makers about their own labouring subjectivities, and qualitative analysis of relevant academic literature and cultural policies, this article critically explores how class inequalities are understood, reproduced, negotiated or resisted within contemporary British documentary film-making. The research findings demonstrate that documentarians from socially disadvantaged backgrounds are more likely to face significant obstacles in the film-making sector than their privileged counterparts. While the majority of respondents are aware of structural disadvantages, champion more inclusive forms of creativity and are committed to improving discriminatory working conditions, a small number of participants believe that the social relations of documentary film production are meritocratic, can be characterised by their celebration of neoliberal values and a willingness to defend the industry's employment practices. The article concludes with a series of recommendations for creative organisations, government and policymakers.
