Estimation of a generalist meso-carnivore (black-backed jackal) population from a fenced protected area
Full text linkSince 2017, landowners, field guides, and management staff have reported large groups of black-backed jackals (Lupullela mesomelas) (here-forward jackal) in the Welgevonden Game Reserve, Limpopo, South Africa. This is linked with several observations of jackals predating on various ungulate species, potentially leading to unintended consequences on prey populations. These observations combined with an apparent poor survival rate of impala (Aepyceros melampus) and continuous declines in their number led to the perception that jackals could be partly responsible. Several studies have attempted to describe the ecological role of jackals within multiple environments, most of which have proven to be variable and context dependent. Human-modified landscapes along with the fencing of protected areas, may have manipulated the role of jackal within these scenarios. Jackals are wide-ranging and generally not confined by fencing, therefore their population trends possibly fluctuate within these anthropogenic landscapes. Re-introduced apex predators have been shown to facilitate food (provision of carrion) and simultaneously suppress jackal (active killing), this, however, remains difficult to predict. Jackals are classified as facultative cooperative hunters, and the term describes how they hunt in groups opportunistically when suitable resources of prey are available. The indication by several studies that jackals do actively predate rather than only scavenge, illustrates that the species has the potential to cause declines in an ungulate population. It therefore appears erroneous to exclude the species in terms of predator-prey relationships, particularly for land managers of fenced protected areas. The first step to any ecological management is the understanding of population size and trends over time. Unfortunately, little to no reliable methods exist to assess or monitor jackal populations. A popular tool for cryptic and wide-ranging terrestrial carnivores is Spatial Capture Recapture (SCR) models, typically through a camera trap array. These often rely on individual identities and an imperfect detection process to derive a statistical estimate of a given area. Jackals have been assumed to be individually unidentifiable and therefore these methods have largely been excluded. To address this a pilot-targeted camera-trap survey was conducted to improve capture and image quality. Following the role of this procedure, semi-automated software was applied to test the feasibility of individual identifications of captured images. This resulted in a subset of 58 right and left identifiable flank images, compiled from the highest graded images (n = 220) using the open-source Interactive Individual IdentificationSystem Beta Contour 3.0 (I3S Contour). I3S Contour assists users by distinguishing between unique contours on independent flanks without omitting observer effort and ranking. The effectiveness of the identification procedure was evaluated using three software tool trials, namely Computer-aided Annotation, Manual Contour Annotation, and Manual Contour Annotation (MA-2), where MA-2 included additional user-defined meta-data to images. Results showed that jackals could be individually identified from camera trap images and thus opened up the use of previously excluded SCR methodologies. Utilising the jackal database derived from the identification procedures described a total of 28 complete identifications (both flanks matched), 32 left-sided and 36 right-sided captures were used. These were derived from two independent survey periods split between seasonality (Winter & Spring). Two SCR methods were compared, namely, the Spatially Explicit Camera Recapture (SECR) and the newly developed Spatial Presence-Absence (SPA) modelling approach. SECR relies on full individual identification linked to spatial locations to derive spatial parameters to estimate population densities. The SECR methodology has been considered the most precise and was thus used as the benchmark. SPA relies on detections only (i.e., without individual identities), along with informative or uninformative priors. This must be across a spatial array that has detectors close enough to allow for simultaneous detections during each occasion (< 24 hours). Comparisons between these model outputs indicated a high degree of confidence interval overlap; however, SPA had a consistently higher posterior mode density estimate (63-64% higher), where the coefficient of variation between outputs also indicated the SPA having a closer relative precision. The targeted survey results for both model outputs for 2021 did not appear unusually high when compared to other studies. To assess the WGR population size over the long term, opportunistic by-catch data from a nine-year leopard (Panthera pardus) camera survey (Panthera organisation) was utilised. Model outputs from each of the years indicated that population estimates remained relatively stable. This was an unexpected result as the SPA densities did not follow the detection observations. This could be attributed to M not being set high enough (200) and the model reaching the limit, resulting in similar outputs between years. An alternative explanation is where the station spacing is larger than the diameter of the home range, which may reduce spatial correlation.Thesis (MSc) -- Faculty of Science, School of Natural Resource Science & Management, 202
Investigation of the host potential of compounds derived from tartaric acid, succinic acid and 1,4-cyclohexanedioic acid
Full text linkThe present investigation considered the host behaviour of three compounds, namely (+)-(2R,3R)-1,1,4,4-tetraphenylbutane-1,2,3,4-tetraol (H1), 1,1,4,4-tetraphenyl-1,4-butanediol (H2) and cyclohexane-1,4-diylbis(diphenylmethanol) (H3) in various guest mixtures. These host compounds were readily synthesized by means of Grignard addition reactions on the diesters of tartaric acid, succinic acid and 1,4-cyclohexanedioic acid. The guest mixtures included cyclopentanone, cyclohexanone, cycloheptanone and cyclooctanone, γ-butyrolactone, 2-pyrrolidone, N-methyl-2-pyrrolidone and N-ethyl-2-pyrrolidone, and pyridine, 2-methylpyridine, 3-methylpyridine and 4-methylpyridine. Crystals of (+)-(2R,3R)-1,1,4,4-tetraphenylbutane-1,2,3,4-tetraol (H1) were grown from cyclopentanone (5-ONE), cyclohexanone (6-ONE), cycloheptanone (7-ONE) and cyclooctanone (8-ONE,) producing 1:1 host:guest complexes in each instance. Thermal analysis showed the thermal stabilities of these complexes to be in the order 6-ONE > 7-ONE > 8-ONE > 5-ONE which correlated exactly with results from binary guest/guest competition experiments, where 6-ONE was always preferred by H1, while 5-ONE was consistently disfavoured. Single crystal X-ray diffraction (SCXRD) analyses demonstrated that each guest compound was retained in the crystals by means of a hydrogen bond with an alcohol moiety of the host compound. Furthermore, preferred guests 6- and 7-ONE produced crystals with greater densities than guests less favoured (5- and 8-ONE). A conformational analysis of the guest geometries in the four complexes with H1 revealed that the low energy guest conformers were present. The host selectivity for 6- and 7-ONE was proposed to be due to the improved molecular packing in the crystals of the complexes containing these two guest compounds, observed from their higher crystal densities. Hirshfeld surface analyses were not useful in explaining the preference of H1 for 6-ONE relative to 7-ONE (these types of analyses were not possible for the 5-ONE and 8-ONE-containing inclusion compounds due to the nature and degree of disorder present in the guest molecules). H1 was also crystallized from γ-butyrolactone (GBL), 2-pyrrolidone (NP), N-methyl-2-pyrrolidone (NMP) and N-ethyl-2-pyrrolidone (NEP), and 1H-NMR spectroscopy revealed that all but GBL were included. The host compound was also presented with these guest solvents in various mixtures, and it was observed that NMP was an extremely favoured guest solvent, followed by NEP and NP, with GBL being consistently disfavoured in every experiment. It was therefore shown that in certain instances, H1 may serve as an alternative tool for separating some of these mixtures through host-guest chemistry strategies. The hydrogen bonding motifs present in each of the successfully formed complexes were extensively investigated through SCXRD analysis, as was the thermal behaviour of these complexes. In the latter instance, the peak temperature of the endotherm (from the DSC trace) representing the guest release was greater for the inclusion compound with favoured NMP (145.5 °C) relative to the complexes with NP (139.8 °C) and NEP (120.5 °C). Host compounds H2 and H3 were revealed to have the ability to include each of pyridine (PYR), 2-methylpyridine (2MP), 3-methylpyridine (3MP) and 4-methylpyridine (4MP). H2 displayed selective behaviour for 3MP and 4MP when presented with mixtures of these guest compounds, whilst H3 preferred PYR. In the latter case, this PYR-containing inclusion compound was also the more stable one (the guest release onset temperature was highest, Ton 66.0 °C). It was demonstrated that H2 has the ability to separate very many binary mixtures of these pyridines on a practical platform, since K (the selectivity coefficient) values were 10 or greater in many instances. However, unfortunately, the more difficult-to-separate mixtures containing 3MP and 4MP cannot be purified or separated by employing H2 and supramolecular chemistry strategies. H3 was also shown to be a likely candidate for binary guest separations in very many of the guest solutions considered here, where K was also 10 or greater, and even infinity in many cases. SCXRD demonstrated that 2MP, 3MP and 4MP were retained in the crystals of their complexes by means of classical hydrogen bonds with the host compound. Satisfyingly, this hydrogen bond between 2MP and H2 (3.0213(18) Å) was significantly longer than that between this host compound and both disorder components of 3MP (2.875(2) and 2.825(9) Å) and that between H2 and 4MP (2.8458(13) Å). This observation explains the affinity of H2 for both 3MP and 4MP, and why 2MP was disfavoured. The results of thermal experiments did not wholly concur with observations from the guest/guest competition experiments. Hirshfeld surface analyses were also conducted but were not entirely conclusive with respect to explaining the host selectivity behaviour. In the case of H3, SCXRD analyses revealed that favoured PYR experienced a classical hydrogen bond with the host compound that was statistically significantly shorter (2.795(2) Å, 165°) than those between the other guest compounds and H3. Additionally, this guest compound was the only one to be involved in a (host)C−H···π(guest) interaction (2.91 Å, 139°) and also a non-classical hydrogen bond with the host compound ((host)C−H···N−C(guest), 2.77 Å (144°)). Finally, Hirshfeld surface analyses showed also that preferred PYR experienced a greater percentage of C···H/H···C (33.1%) and H···N/N···H (11.1%) interactions compared with the complexes with 2MP, 3MP and 4MP. However, it is not clear whether these Hirshfeld observations explain the affinity of H3 for PYR.Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 202
The role of visual storytelling in enhancing online learning experience design at Nelson Mandela University
Full text linkAs the landscape of higher education undergoes a shift toward a combination of online instructional methods and traditional in-person engagement, a creative approach becomes essential in ensuring student success. The research aims to explore how visual storytelling can enhance the online learning experience at Nelson Mandela University (NMU), thereby improving the effectiveness of teaching and knowledge acquisition. This study delves into the Learning Experience Design (LXD), a blend of instructional design, design thinking, and user experience design, within the teaching community of Nelson Mandela University and the broader South African context. Employing a mixed-method approach, qualitative data from interviews identified themes such as the improvement of LXD, challenges in the design process, and the utilization of visual storytelling. Quantitative analysis revealed that students primarily used the university learning management system (Moodle) for accessing resources, grades, and reviewing tests, with limited engagement in online learning activities. Lecturers expressed concern about Moodle’s functionality, a need for enhanced design support, and the necessity for training in the transition to digital learning. While lecturers recognized the potential of visual storytelling in enhancing engagement and knowledge retention, they emphasized the importance of support for the seamless integration into teaching. Students acknowledged the positive role of visual storytelling in improving their learning experience but highlighted areas of improvement, such as regular updates, increased visual interaction options, and the inclusion of information graphics to explain concepts. A design thinking process informed the development of instructional design interventions, leading to the creation of a prototype Moodle course shell and resources. This initiative aims to empower lecturers to enhance the learning experiences independently with the support of professional LXD services. The research findings suggest that visual storytelling indeed improves LXD, emphasizing the need for established support systems and resources at the university to equip lecturers for successful integration.Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 202
The role of hashtag activism in advocating against gender-based violence and promoting perpetrator accountability : subtitle if needed. If no subtitle follow instructions in manual
No full textThis study is aimed at determining the role that hashtag activism has played in advocating against gender-based violence (GBV) and promoting perpetrator accountability. The study used major GBV hashtags such as #MeToo, #WhyIStayed and #AmINext to investigate how effective these hashtag movements have been in breaking the silence around GBV and fighting against GBV. The study made use of both qualitative and quantitative research methodology, which was useful to gain a deeper understanding of GBV and all the social and cultural practices that perpetuate it. Qualitative data were collected by means of interviews and tweets under the selected hashtags. An online survey questionnaire was used to collect quantitative data. The data provided an understanding of the complexities surrounding GBV and people’s views on hashtag activism and GBV. Through the data analysis, the study found that hashtag activism has been effective in changing dominant discourses, advocating against GBV, creating awareness and solidarity around GBV issues, and promoting perpetrator accountability. The study calls for a global collective effort to develop, record and archive feminist initiatives so that all the structural conditions which enable and perpetuate sexual violence are exposed and cannot be forgotten or ignored. Future research should look into how harmful societal norms can be challenged and how the effectiveness of hashtag movements can be enhancedThesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 202
Assessing the management of water services in Fairview, Harry Gwala district municipality
Full text linkThis study sought to assess the management of water services in the Fairview community within the Ixopo town under the Harry Gwala District Municipality (HGDM). The study was further motivated by the need to ascertain stakeholders’ perceptions on the response to water shortage challenges in the Fairview community, assess Fairview community members’ knowledge, and identify opportunities brought about by water shortages in this community. The study was anchored on the service quality model (SERVQUAL) as the theoretical framework. The research design of the study was exploratory and used both qualitative and quantitative methods. The target population of the study consisted of ordinary members of the Fairview community and managerial staff at the HGDM. The qualitative part of the study involved eight (n = 8) managerial employees at the municipality. In total, 120 questionnaires were despatched, and 110 were returned, which gave a 92% response rate for the quantitative part of the study. The questionnaire respondents were chosen by random sampling, while the interview respondents were chosen by purposive sampling. The quantitative data were analysed using descriptive and inferential statistics, while the qualitative data were analysed using applied thematic analysis. The study revealed that there is generally a negative perception of the municipal responses to addressing water supply challenges and that the municipality does not always act promptly to water supply challenges. Perceptions of poor-quality service provision regarding responsiveness, reliability, assurance, and empathy were found. The findings also revealed that the Fairview community members are generally knowledgeable about water conservation. The study unveiled opportunities for addressing water supply challenges, such as mobilising funds from stakeholders to build additional water reticulation, harvesting capacity, and modernisation of water management, and recommends that the municipality immediately conduct public participation meetings and citizen satisfaction surveys to ascertain community service delivery expectations, followed by developing service quality standards and performance agreements with municipal staff to improve residents’ perceptions of the municipality’s ability to respond to water supply challenges.Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 202
Plankton and macroinvertebrate dynamics in the Khakhea–Bray transboundary aquifer region
Full text linkTemporary wetlands are prevalent in semi–arid and arid climates across the globe and harbour unique faunal assemblages that significantly contribute to regional aquatic biodiversity. This study aims to enhance our understanding of the ecological dynamics of temporary wetland ecosystems, focusing on plankton dynamics, large branchiopod diversity, trophic dynamics, water quality and the impacts of freshwater salinisation in temporary pans in the Khakhea Bray Transboundary aquifer region in the North west Province, South Africa. This body of work represents field, laboratory and writing components which span the period May 2021 to December 2023. The results from this study revealed seasonal patterns in plankton diversity with a winter peak in phytoplankton diversity dominated by Zygnematophyceae species, while Chlorophyceae were dominant in summer. Zooplankton diversity was high in summer as compared to winter, with both Rotifera and Copepoda dominant in both seasons. Six large branchiopod species were found in the region, and three of these were new distribution records for the North west Province, including the first record of Phallocryptus spinosa in the salt pan that was sampled in summer. Large branchiopod diversity was mainly influenced by water temperature and phosphorous in summer, while sediment sodium influenced the diversity in winter. The stable isotope analyses used to determine trophic dynamics in these temporary pans revealed that the food web had four trophic levels, with the top predators being the notonectids Anisops sp. The dominant consumers were predatory insects such as Sigara sp., Anisops sp., Lestes sp., Rhantus sp. and Cybister sp. adults and larvae, as well as detritivorous Tomopterna sp. tadpoles. High trophic niche overlaps were found between the notonectids and the dytiscids. These temporary pans are susceptible to anthropogenic impacts, and disturbed pans were found to have elevated pH, ammonium, phosphates and dissolved oxygen compared to the undisturbed pans. A strong positive relationship was observed between chl–a and temperature, pH, dissolved oxygen, phosphates and ammonium. Chlorophyll–a concentration increased as surface area and the distance from kraals, buildings and latrines decreased. Freshwater salinisation was found to cause notable shifts in abiotic factors and benthic phytoplankton communities, favouring the proliferation of saline–tolerant diatom species at the cost of more sensitive taxa. The study also revealed that in interaction with salinisation, time also exerted a notable influence on shaping the benthic phytoplankton community. Salinity levels of 2.5 ppt and above led to significant decreases in emergent taxa richness and abundance, with Spinicaudata and Ostracoda being the most sensitive taxa to high salinities. There was a limited effect on community hatching phenology dynamics from salinity. This suggests that the main impact of salinisation in these systems will be reductions in hatching success and, hence, reduced recruitment. The study highlights the vulnerability of temporary pan ecosystems to anthropogenic influences and the complexities of interactions of organisms and the environmental conditions in these systems.Thesis (PhD) -- Faculty of Science, Zoology and Entomology, 202
Lemons or Lemonade? Examining the economic and social outcomes of engaging in the export-driven citrus value chain of South Africa for selected commercial citrus farmers and farm workers in the Raymond Mhlaba Municipal District, Eastern Cape
Full text linkThis study examines the economic and social outcomes of participating in a global citrus value chain for selected commercial farmers and farm workers in Raymond Mhlaba Municipal District in the Eastern Cape, South Africa. A global chain refers to international production sharing through cross-border trade. Multilateral organizations (and some prominent global chain scholars) that support neoliberal economic globalization perceive global chains as ideal channels of economic and social upgrading for participants, particularly those from the global South. From the abovementioned perspective, global chains enhance efficiency through inter-firm relations that promote the distribution of technology and access to capital, thus leading to economic and social upgrading in developing countries. Economic upgrading, on the one hand, can briefly be described as the movement of supplier firms from lower to higher-value activities in global chains. Social upgrading, on the other hand, is the improvement of employment conditions and outcomes of workers employed by supplier firms at the production node of global chains. This study adopts the dual theoretical framework (Global Chain Framework and Labour Process Theory) proposed by Newsome, Taylor, Bair and Rainnie (2015) in their seminal book ‘Putting Labour in its Place: Labour Process Analysis and Global Value Chains’. This dual framework is ideal because it conceptualizes the spheres of trade exchange and production, which are the primary research sites of this study. Qualitative research methods were adopted and utilized to collect and analyse data in this study. These methods were ideal for this study, as they captured the subjective accounts of the selected commercial citrus farmers and farm workers in the Raymond Mhlaba Municipal District in the Eastern Cape, South Africa. The findings in this study showed that the outcomes of these selected commercial citrus farmers and farm workers in this region are variegated, meaning that, there is evidence of economic upgrading, social upgrading and social downgrading as well. Amongst farm workers in the region, only a small group of (mostly older male) farm workers enjoyed social upgrading, whilst the majority of seasonal (mostly female) farm workers experiences social downgrading. The findings in this study showed that the variegated economic and social outcomes of the selected commercial farmers and farm workers were primarily determined by their economic class and position within the citrus value chain of South Africa. These findings highlight the importance of positionality in determining the fate of participants in global chains.Thesis (MA) -- Faculty of Humanities, Sociology, 202

Dictionaries as pedagogic tools: a case study of selected schools in Makhanda, Eastern Cape
Full text linkThe importance of dictionaries in society has been confirmed in relevant literature while their specific role in education is underlined by several studies focused on the use of dictionaries in teaching and learning. This study focuses on mother-tongue or first language (L1) isiXhosa learners and their use of dictionaries across subjects in the Intermediate Phase of primary schooling. The research sought to examine how dictionaries are used in teaching and learning and how they could be used more effectively in the teaching and learning processes, with a focus on isiXhosa L1 learners in the Makhanda area of the Sarah Baartman District of education, Eastern Cape. The general aim of this study was to improve the process and practice of using and producing Language for General Purpose (LGP) and Language for Specific Purpose (LSP) dictionaries across subjects. The study also sought to contribute to improving the functional value and user-friendliness of teaching support materials, such as dictionaries. The Curriculum and Assessment Policy Statement (CAPS) policy document states that dictionaries are essential in teaching and learning of both language and content subjects. In relation to language subjects, the CAPS is explicit about the use of dictionaries in the acquisition of vocabulary, meaning, spelling, pronunciation, and grammar, among other types of information that are integral in language attainment and learning. Nonetheless, the CAPS document does not clearly articulate the use of dictionaries in content subjects. The study draws on two branches of lexicography – namely, dictionary user research and dictionary criticism – to examine the extent to which dictionaries are problem-solving tools which assist users to meet their cognitive and communicative needs. Thus, the study seeks to influence policy and practice of the use of dictionaries as teaching and learning resource materials that could help teachers and learners better understand key concepts across subjects. A mixed-method approach was used to collect both quantitative and qualitative data using a variety of data collection instruments, viz., observation schedules, questionnaires, and interviews. The study found that although teachers were aware of dictionaries, they did not use them as a resource in teaching. Furthermore, teachers lacked skills in the use of dictionaries, therefore, they were not able to effectively integrate dictionaries in their lessons. The research also found that learners had little awareness of dictionaries and did not fully understand their role in language acquisition or content. Lastly, the study offered some insights on how dictionaries could be integrated in teaching and learning, and how their use could address some communicative and cognitive problems faced by non-mother tongue English speakers in a context where English dominates teaching and learning at the expense of learners’ L1.Thesis (PhD) -- Faculty of Humanities, School of Languages and Literatures, 202
Issues in language acquisition planning in Zimbabwe: the case of Ndebele within the primary education system
Full text linkThis thesis discusses pertinent language issues within the primary school system in Zimbabwe in view of complaints (over many years) of communities in the two Matabeleland provinces and Bulawayo about high failure rates of learners in the final grade 7 examinations. It also interrogates the government’s commitment to the development of indigenous languages in the primary school system, particularly in the three provinces mentioned above as mirrored in the 2013 constitution of the country. The study conducted traces the language trends exhibited currently back to their beginnings during the colonial era in language planning by the government and the policies that informed such planning. What obtains on the ground seems to be violating the principles behind the declaration of the International Mother Language Day (30C/62) proclaimed by the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO) in November 1999. On 16 May 2007 the United Nations General Assembly, in its resolution A/RES/61/266, called upon Member States (Zimbabwe included) "to promote the preservation and protection of all languages used by peoples of the world". The amended education act of 2006 states that in Zimbabwe’s primary schools early learning must be done through mother tongue instruction then switch to English in grade 4 upwards. As a first step of a child’s academic life, the lower primary education needs to be conducted in the child’s mother tongue to bridge the gap between the child’s home environment and the new school environment as well as to reduce culture shock associated with the sudden introduction of a new language. Studies, such as those done by Noormohamadi, (2008) and Mackenzie, (2013) have shown that children tend to understand better if they are taught in their mother tongue. In this thesis I seek to establish if the teaching of Ndebele at primary school reveals the socio-cultural ideology (awareness of circumstances surrounding individuals and how their behaviours are affected, specifically by their surroundings, social and cultural factors) and political ideology (thinking structures about the way policies should be run) underpinning language planning in Zimbabwe. It is my observation and argument that the Education Act proclaims what has not been practised on the ground through teacher training and deployment practices. To establish if the teaching of Ndebele at primary school reveals the socio-cultural and political ideologies underpinning language planning in Zimbabwe, I carried out research in Matabeleland South, Bulawayo and Matabeleland North provinces covering a total of 27 schools, 27 heads of school and 135 teachers. The research’s main aims were to find out if Ndebele was taught at school, by who and using what materials. It should be noted that mother tongue, in learning, acts as a basis of interpretation of subsequent concepts. When a child is learning new concepts or words in the second language, he or she first searches the equivalent in his or her mother tongue. If the primary language has not been developed well enough to have such equivalents, such a child is likely to have problems in forming new concepts in the second language. The role of language in meaning, therefore, is a variable that depends on the socio-geographical location of the languages and their speakers. The research established that, indigenous languages, Ndebele included, are not developed by the government through financial support for teaching material production and qualified teacher deployment. Instead, it was discovered that in Matabeleland there are some learners at primary school who are taught by a Shona-speaking teacher who cannot communicate properly with the learners. It should be remembered that a primary language is used by a child as the foundation to learn the basic concepts in his or her own language and to give him or her freedom to express himself or herself without the inhibitions imposed by an insufficient mastery of the medium of instruction. As a way of concluding the research I found it necessary that the use of mother tongue by learners at lower grades of primary school be strengthened through the deployment of teachers who can teach Ndebele properly because it provides a strong foundation for further education. Using the mother tongue, students learn to think, communicate and acquire an intuitive understanding of grammar. The mother tongue is; therefore, the greatest asset and vital tool people use to acquire new concepts.Thesis (PhD) -- Faculty of Humanities, School of Languages and Literatures, 202
