A comparative study of the meaning and value of university campus architecture in southwestern Nigeria
(Department of Architecture, Obafemi Awolowo University, Ile – Ife, Nigeria., 2024) Akinsola, Musiliu Lawal.
This study examined comparatively the meaning and value of campus architecture of two universities in Southwestern Nigeria. It examined the personal characteristics of users of the University of Ibadan and Obafemi Awolowo University campuses, examined the physical and socio-physical characteristics of the two university campuses. Analysed the meaning and value of the two university campus architecture, and compared the architecture of the two university campuses. These with a view to providing information that could enhance university campus architecture. A mixed method of quantitative and qualitative evaluation with physical observation was used to collect primary data, while secondary data were sourced from relevant departments. The campus architecture of Obafemi Awolowo University and University of Ibadan, with two classes of respondents; university – staff and students, comprising of 42 and 63 staff, with 401 and 366 students from OAU and UI respectively, were selected using purposive sampling method. The measuring instruments comprised of campus users personal characteristics, physical and socio- physical characteristics of the campus architecture, which were used to assess meaning, while open responses of campus users, likes and dislikes, mental imagery, campus users memories and most important things assessed users’ value of campus architecture which aligned with meaning. Data obtained were analysed using descriptive analysis, means, percentile, chi-square, Cronbach’s Alpha factor analysis, Kruskal-Wallis ANOVA, Crosstabulation, content analysis and Fisher Freeman p-values. Obafemi Awolowo University and University of Ibadan campus architecture evoked campus users’ meaning and value, namely, architecture vitality, campus ambience, quality, wellbeing, campus aesthetics and privacy, circulation and recognition, inclusivity and accessibility, crowding, and facility recognition and cosiness. OAU campus users ranked architecture vitality the strongest in meaning (0.851 Cronbach’s Alpha score; 5.44 mean value) while, UI users ranked campus ambience the strongest in meaning (0.888 Cronbach’s Alpha score; 5.0 mean value). The weakest ranked users meaning was campus facility distinction and cosiness (0.472 and 0.110, Cronbach's Alpha score) and mean value (4.32 and 4.20) for OAU and UI respectively. Also, campus users’ personal characteristics resonates in campus architecture meaning and value, OAU and UI users’ knowledge of the campus was significantly different in all the meaning except for campus crowding (OAU, p < 0.804; UI, p value < 0.245) and facility recognition in OAU (p value < 0.743). For OAU and UI users’ age and number of years on campus was significant in architecture vitality, campus ambience, wellbeing, aesthetics and privacy, circulation and recognition. Religion was significantly different in UI architecture vitality (p < 0.029) and OAU campus quality (p < 0.012), gender was significant in OAU’s circulation and recognition (p < 0.017), wellbeing (p< 0.031). The study concluded that Obafemi Awolowo University and University of Ibadan campus users’ meaning and value were distinct, distinguishable and different. Campus users’ meaning and value of Obafemi Awolowo University campus architecture was stronger than those of University of Ibadan campus users.

A Criritical Assessment and Defence of the Legalisation
(Department of Philosophy, Faculty of Arts, Obafemi Awolowo University, 2022) FOLORUNSHO, Martha Tosin
The study explicated and clarified the concept of euthanasia. It also examined arguments for and against euthanasia. The study also defended the idea of self ownership. This was done with a view to showing that the moral permissibility of euthanasia on the basis of self ownership provides a plausible ground for the legalization of euthanasia. This study adopted the method of philosophical argumentation, critical analysis and conceptual clarification of data collected from both primary and secondary sources. The Primary sources included works of philosophers such as: P.A Singer and M. Siegler Euthanasia: A Critique, Behnke, A. and Bok Sissels, (eds.) The Dilemma of Euthanasia, Jonathan G. Causing Death and Saving Life, Reisser, S. J Euthanasia, Joel Feinberg “Harm to self: The Moral Limit of Criminal Law”, Micheal Lacewing “Well-Being and Death” and D. Belgium “The right to die at the end of your life.” The secondary sources will include books, journal articles and the Internet. The data collected were subjected to critical analysis and philosophical argumentation. The study found that the concept of euthanasia has various meanings. It also found that the various arguments for and against euthanasia are inadequate because they did not pay adequate did not pay adequate attention to the concept of self ownership. Thus, the study found that the concept of self-ownership provides a plausible basis for the moral permissibility of euthanasia. The study concluded that the moral permissibility of euthanasia presents a justifiable ground for its legalization.

(Department of Linguistics and African languages, Faculty of arts, Obafemi Awolowo University., 2022) ADEMUYIWA Adewale Lukman
The study identified the issues of identity and cultural affinity of Òke Ògùn people of Oyo North Senatorial District in the oríkì of their towns. It also examined the concept of the oral formulaic and intertextuality in the oríkì of towns in Òkè-Ògùn. It further analysed the thematic contents and assessed the stylistic features in oríkì of Òkè-Ògùn towns. These were with a view to bringing to the fore, oral literary and stylistic qualities in the oríkì of Òkè-Ògùn towns. The study employed both primary and secondary sources of data. The primary source comprised a collection of Oríkì of forty towns in Oke-Ogun area of Oyo State gathered from oral, written, audio and audio-visual materials. This was complemented with interviews conducted with 40 purposively selected chanters, drummers and historians, to get more details on Oríkì and historical background of towns in Oke-Ogun. The secondary source included books, journal articles, magazines and the Internet. The collected data were transcribed and analysed within the general theoretical framework of Archetypal theory and Genetic Structuralism. The study revealed that dialect, geographical locations, occupations, religions, beliefs, political structure and oríkì composition patterning are the archetypal elements of identity and cultural affinities of Òke-Ògùn people. The study further revealed names of towns, archetypal founders, archetypal situations, archetypal slangs, kinship terminologies and nominalization as xxiv the oral formulaic used in the formulation of oríkì of towns in Òke-Ògùn, while the insertion of other Yorùbá oral genres such as proverbs, incantation, Ifa literary corpus and songs are concepts of intertextuality in the oríkì of towns in Òke-Ògùn. Also, the study showed that the thematic contents in the oríkì of Òkè-Ògùn towns show common features of reference to their ancestors, origins, behaviours, taboo, foods, deities, manifestation of power, anthropological artefacts and the reference to geographical elements like mountain, rivers and forests. The study further revealed that foregrounded metaphor, simile, metonymy, hyperbole, personification, objectification, repetition, pun, tonal play, onomatopoeia and phonal-aesthetics are notable stylistic features embedded in the oríkì of towns in Òke-Ògùn for aesthetic purpose. The study concluded that the oríkì of towns in Òkè-Ògun showed that geographical locations are not the only indices that bind all these communities together; they also shared common archetypal attributes embedded in their oríkì. Also, oríkì is perceived as a repertory oral poetry through which archetypal elements are kept for incoming generations.

A Critical Assessment of the internalist theory of Epistemic justification
(Department of philosophy, Faculty of Arts, Obafemi Awolowo University., 2022) Olusola Ayomide Asaju
The study identified and examined different versions of internalism as a theory of epistemic justification. It also examined the problems associated with the internalist theories of epistemic justification. Furthermore, it argued for the plausibility of the mentalist version of internalism as a theory of epistemic justification. This was done with a view to grounding the justification of knowledge claims mainly on internal factors without denying significance to external factors. The study employed both primary and secondary sources of data. The primary source included, Bonjour Laurence “Externalism and Internalism”, Ernest Sosa and Bonjour Laurence. Epistemic Justification: Internalism vs. Externalism, Foundations vs. Virtues, Alston Williams Internalism and Externalism in Epistemology, Fumerton Richard “What and what is Internalism?”, Ralph Wedgwood “Internalism Explained”, Alvin Goldman “Internalism Exposed”, Frederick F.S. Knowledge and Belief and Edmund Gettier’s “Is Justified True Belief Knowledge?”. The secondary source included books, journal articles and the Internet. The data collected were subjected to critical analysis and philosophical argumentation. The study found that epistemic internalism has various versions. It found that most versions of internalism are not plaussible because they do not account for the role of externality in epistemic justification. Furthermore, the study found that mentalism, as a viariant of internalism, acknowledges the significance of external factors in the justification of knowledge claims. Thus, the study concluded that the viability of the mentalist theories further supports the possibility of the internalist position on epistemic justification. It also found that not all versions of internalism absolutely reject the relevance of externality in epistemic justification.

A critical discourse analysis of fake news and hate speech among Nigerians in selected social media sites.
(Department Of English, Faculty Of Arts, Obafemi Awolowo University., 2023) Adewuya, Abiola Omotayo
The study identified the patterns of language use in fake news and hate speech among Nigerians on the selected social media sites. It analysed the discursive strategies projecting identities and ideologies in the selected texts. It further described the use of language militating against peace and or promoting discord in the selected texts and discussed the implications of the use of language in the Nigerian context. All these were done with a view to uncovering the underlying issues of identity and ideology in the Nigerian wider contexts. The study used both primary and secondary sources of data. The primary source comprised 50 purposively selected fake news and 50 purposively selected hate speeches making 100 altogether. Among the 10 commonly used social media platforms in Nigeria, Facebook, Twitter and WhatsApp were selected based on perceived popularity and acceptance among Nigerians. The secondary source included books, journal articles and the Internet. The study adopted van Dijk’s socio-cognitive model of CDA with bias for his ideological square drawing insights from Gumperz’s Interactional Sociolinguistics to analyse the data. The results showed that discourse producers on social media used patterns of language including lengthy titles, capital letters, lexicalisation, punctuation marks and slangy words/expressions in the fake news and hate speeches to emphasise issues and present people. The study also revealed that social media users discursively used language to showcase Self and Other identities in ethnic, religious, social and political forms with the use of figures of speech e.g. consonantal alliteration, metaphor, irony and synechdoche while ideologies of marginalisation, ethnic and religious biases etc. were expressed with discursive strategies such as actor description, categorisation, example/illustration, evidentiality, generalisation, national self(de)glorification, number game among others. It further revealed that fake news and hate speeches’ discursive features reflect negative presentations of different ethnicities and political office holders which mitigate against peace and/or promote discord in Nigeria. Finally, the study found that the implication of language use in fake news and hate speech on social media reflects resistance to domination and power abuse of the political class in the Nigerian context. The study concluded that fake news and hate speech on the social media reflect individual and collective ideologies reflective of the socio-political nature of Nigeria through which different identities are marked.

(Department of English, Faculty of Art, Obafemi Awolowo University, 2023) ADENIYI, Sijuwade Toyin
This study identified the peculiar lexical features in the selected government documents and correspondences. It analysed the structural patterns of the selected documents and correspondences. It also examined the functional contexts of the identified lexical and grammatical features in the selected documents and correspondences, and further discussed the implications of the language usage in governmental documents and correspondences on the characterisation of Nigerian English as a recognised regional variety of English in the world. This was with a view to showing the peculiar uses of language in the domain of State Government administration. This study employed both primary and secondary sources of data. The primary source comprised 80 purposively selected correspondences and documents from the Public Service Office of Lagos State Government, Alausa as well as their websites. These correspondences comprised 25 letters, 25 memos, 20 circulars and 10 press releases recently archived between 2015 and 2021. The press releases were fewer than the other documents because they were lengthier than them. The secondary source included books, journal articles, and the Internet. The data collected were analysed using Hengeveld‘s Functional Discourse Grammar (2000) and Halliday‘s Systemic Functional Grammar (1985). The results showed that lexical items such as repetition, synonyms, antonyms and identification are foregrounded lexical features in the selected documents and correspondences. The study found that the documents and correspondences were most characterized by complex sentence structure, embedding, passivation and nominalization. It further revealed that the identified lexical items featured most prominently in circulars and press releases. Finally, the study discovered that the uses of language within the Civil Service of State Government of Lagos have implications on power structure among the officials. The study concluded that the deployment of language in government is formal, standard, polite, courteous, clear and devoid of ambiguity and misinformation.

A phonological description of the anglicized Yoruba name transcriptions in the Collins online English dictionary and Yoruba native speakers’ perception
(Department of English, Obafemi Awolowo University., 2024) Abass, Abiola Sakariyau
This study identified the orthographical representation of selected anglicized Yoruba names in the Collins Online English Dictionary. It described the Yoruba native speakers’ perception of the selected transcribed names and discussed the socio-cultural implications of the transcribed names in language contact situations. This was done with a view to investiging the semantic effects of the phonological transcriptions of the selected Yoruba words in the dictionary. The study employed both primary and secondary sources of data. The primary source comprised 20 names of Yoruba origin extracted from the 13th edition of Collins Online English Dictionary. Twenty-five Yoruba native speakers were purposively selected to undertake verification task and a read-aloud exercise of the selected Yoruba names to assess the accuracy of Yoruba name transcriptions in the dictionary. For the verification task, participants were given an audio recording, along with a partially completed written transcript of the recording and tasked with completing the written transcript by filling in the missing words based on their perception of the audio recording. The goal was to assess their perception of the transcriptions as presented by the dictionary. Similarly, a prepared word list comprising the 20 extracted Yoruba names was presented to each respondent to pronounce while being audio-recorded for the read-aloud exercise, with the aim to capture the actual native-like pronunciation through their audio recordings. Using the International Phonetic Alphabet (IPA), the audio-recorded utterances were phonemically transcribed and compared with the Collins Online English Dictionary version to ascertain the faithfulness of the dictionary to Yoruba name transcriptions. The secondary source included books, journal articles n and the Internet. Theoretical insights were drawn from Keshavarz’s (2011) approach to Contrastive Analysis and the concept of faithfulness in the Optimality Theory of McCarthy (2002) to analyse the data. Findings revealed that the process of anglicization of the selected Yoruba names in the Collins Online English Dictionary involves various phonological adjustments ranging from vowel substitutions and consonant replacements to the adaptation of tone structures within Yoruba names. The study found that Yoruba native speakers exhibited diverse perceptions of the transcribed names. It discovered that while some names are uniformly perceived, others show variations, indicating potential transcription-related influences. The study further showed that the omission of tone markers in the anglicized version not only simplifies the representation but also risks misinterpretation, affecting the accurate conveyance of cultural meanings associated with these words. The study concluded that English dictionaries need to offer more precise and culturally aware transcriptions of Yoruba names, taking into account their phonological features, thus mitigating potential misrepresentations in identity and cross-cultural communication.

A semiotic analysis of linguistic and visual features of statues of selected legendary figures in Yorubaland
(Department of English, Faculty of Arts, Obafemi Awolowo University., 2015) Adefolaju Adefunke Adedayo
The study identified the semiotic components of some Yoruba legendary statues. It analysed the linguistic and visual anchorages that accompany the statues. It further described the social values, cultural and political identities and stances expressed by the linguistic and visual features of the statues. All these were done with a view to enriching the knowledge of statues as a phenomenon of language and foregrounding the discourse wealth of statues as semiotic signifiers of socio-historical significance. The study employed both primary and secondary sources of data. The primary source comprised eleven statues which were purposively selected from six cities in Yorubaland. The selected cities were Ondo, Ile-Ife, Oke-mesi, Ibadan and Abeokuta. The selected statues were closely read with particular attention to their linguistic and non-linguistic meaning making modes. The secondary sources included books, journal articles and the Internet. The analysis of the data was guided by van Leeuwen's Social semiotics and Martins and White's Appraisal theory. The findings showed that the selected statues were composed of primary and secondary signifiers. The study also found that the statues were accompanied by such verbal anchorages as epithets of appreciation and affective memory, nominal signifiers of heroism, positive terms of address, verb signifiers of impressive attitude and local configuration/eulogies. There were also visual anchorages such as warfare symbolism, religion symbols, animal and material signifiers. All these served as indices of affective evaluation. The findings further showed that the statues portrayed such social values as bravery, courage, hard work, enterprise, integrity and patriotism. It was found that legendary statues inscribed leadership, power, social and economic identities, and that their producers also utilised the products to construct stances of positive alignment and judgement which pointed to their attachment to the values which the statues signify. The study concluded that statues of Yoruba legendary figures are discourse products because they elucidated the concepts of power, identity and ideology, which were the subjects of modern day discourse. It also concluded that the statues were semiotic signifiers of the Yoruba socio-cultural realities.
