- Background: Tuberculosis is the world’s deadliest infectious disease and a leading cause of death in Nigeria. The availability of a functional healthcare system is critical for effective TB service delivery and attainment of national and global targets. This study was designed to assess readiness for TB service delivery in Oyo and Anambra states of Nigeria. Methods: This was a facility-based study with a mixed-methods convergent parallel design. A multi-stage sampling technique was used to select 42 primary, secondary, and tertiary healthcare facilities in two TB high burden states. Data were collected using key informant interviews, a semi-structured instrument adapted from the WHO Service. Availability and Readiness Assessment tool and facility observation using a checklist. Quantitative data were analysed using descriptive and inferential statistics while qualitative data were transcribed and analysed thematically. Data from both sources were integrated to generate conclusions. Results: The domain score for basic amenities in both states was 48.8%; 47.0% in Anambra and 50.8% in Oyo state with 95% confidence interval [− 15.29, 7.56]. In Oyo, only half of the facilities (50%) had access to constant power supply compared to 72.7% in Anambra state. The overall general service readiness index for both states was 69.2% with Oyo state having a higher value (73.3%) compared to Anambra with 65.4% (p = 0.56). The domain score for availability of staff and TB guidelines was 57.1% for both states with 95% confidence interval [− 13.8, 14.4]. Indicators of this domain with very low values were staff training for the management of HIV and TB co-infection and training on MDR -TB. Almost half (47.6%) of the facilities experienced a stock out of TB drugs in the 3 months preceding the study. The overall tuberculosis-specific service readiness index for both states was 75%; this was higher in Oyo (76.5%) than Anambra state (73.6%) (p = 0.14). Qualitative data revealed areas of deficiencies for TB service delivery such as inadequate infrastructure, poor staffing, and gaps with continuing education on TB management. Conclusions: The weak health system remains a challenge and there must be concerted actions and funding by the government and donors to improve the TB healthcare systems. 1 results 1

- Despite global calls for a transition to modern energy, Nigerian households continue to face obstacles in accessing clean cooking energy. This paper examines the barriers to household fuel choice in rural and urban areas of Ogun Sate, Nigeria, employing an access framework. Through a cross-sectional study involving 597 households, we examined the factors associated with the selection of household cooking fuel and the access challenges. The framework conceptualises fuel choice as a function of three key access dimensions: affordability, availability, and acceptability, using multinomial logit regression. The findings showed that firewood and kerosene remain Nigeria’s dominant household fuel sources. The results highlight that fuel choice is influenced not only by affordability factors but also by factors related to availability and acceptability. Consequently, the study recommends a comprehensive approach beyond affordability, to ensure modern energy sources are culturally acceptable while establishing secure supply chains towards a more environmentally sustainable energy future. 1 results 1

- Ethno-autobiographical poetry is a culturally constituted autobiographical poetry. Due to its subjectivity, it is regarded by critics as an unreliable construction of social history. Consequently, previous researches consider ethno-autobiographical poetry as essentially self-aggrandising, neglecting its form as a unique blend of both self and culture. Therefore, this study explored the cultural constitution of selected Nigerian migrant and travel literary ethno-autobiographical poetry, in terms of racism, ethos, and space, with a view to establishing its features as a source of social history. The diachronic perspective of the Genre Theory, which emphasises the historical and dynamic function and features of a genre, is adopted to conceptualise autobiography as ethno-autobiography. The historico-biographical method was used to explore how self and culture are constructed in four collections of purposively selected Nigerian migrant autobiographical poems: Tanure Ojaide‘s When it No Longer Matters Where You Live (No Longer Matters), Femi Oyebode‘s Master of the Leopard Hunt (Master), Olu Oguibe‘s Songs of Exile, Uche Nduka‘s The Bremen Poems, and two collections of poetic travelogues: Odia Ofeimun‘s London Letter and Other Poems (London Letter) and Remi Raji‘s Shuttlesongs: America (Shuttlesongs). The texts were subjected to critical textual analysis. Nigerian migrant and travel ethno-autobiographical poetry depicts an interplay of racism, ethos, and space in the authors‘ self construction. In Master, racism is portrayed in the persona‘s treatment as a racial ‗Other‘; ethos is depicted in the appropriation of Benin mythical art and ancestral beliefs as identity schema and for interrogating the episteme of Euro-American geo-space. Songs of Exile depicts racism in the persona‘s hybridity and identity crisis, but ethos in the conflict between his African imagination and Americans‘ individualistic lifestyle, which results from his encounter with the geo-cultural space of exile as a post-colonial subject. The Bremen Poems relates the persona‘s loneliness and vulnerability as a racial outsider, whereas ethos is depicted in his conflicting feelings of nostalgia for the homeland and love for the exilic space of Bremen as a city of refuge. In No Longer Matters, exile is associated with racial discrimination, individualism and deceptive glamour while the homeland is portrayed as oppressive and squalid resulting in the persona‘s conclusion that neither geo-space is conducive for self realisation. In London Letter, Lagos and London are depicted as racially and socially stratified and filthy; ethos is portrayed in the persona‘s queries of Nigerian emigrants‘ Eurocentric disposition and their flamboyant lifestyles as citizens and immigrants within the geo-cultural spaces of Lagos and London respectively. In Shuttlesongs, racism is portrayed in the historic slave trade and racial discrimination occluded by modern America‘s glamour while ethos is depicted in America‘s liberal democracy, human rights, and African American cultural values; the persona encountered these during visits to America‘s historic sites and geo-cultural spaces. The cultural constitution of selected Nigerian migrant and travel literary ethnoautobiographical poetry, in terms of racism, ethos, and space, is composed, respectively, of alterity, identity construction and epistemological orientation, and trans-spatiality. These features demonstrate ethno-autobiography‘s form as an expression of self and culture within the context of social history 1 results 1

- Imported Used Electronics (IUEs) are officially conceived in research oriented policy as potential and actual toxic “solid waste”, yet Nigeria remains a high consumer demand economy for them. IUEs include electronic monitors, digital devices, docking stations, cell phones, hand-held diagnostics, screening tools, television sets among others. Nigerian economy has evolved a socially constructed merchandise structure, which sustains IUEs trade. Literature, however limits IUEs discourses to pure-scientific framing of toxicology and dump in the Third World countries. This study, therefore, examined the subjective meanings that sustain the demand and merchandise of IUEs against official prohibition. Social action theory guided the study. The research design was exploratory. The qualitative research method was used. Data were generated from both primary and secondary sources. The research area was Lagos, and data were collected from Ikeja Computer Village, Westminster Used Electronics Market, Alaba International Market, Apapa Customs Office (ACO) and National Environmental Standards and Regulatory Enforcement Agency (NESREA). Participants were selected through purposive and snow-balling techniques. Non-participant observation for 15 months, In-depth Interviews (IDIs) were held with 22 IUE consumers and 22 market-actors. A total of 15 Key Informant Interviews (KIIs) were held with ACO officers (three), Association Heads of the three markets (eight) and veteran market actors (four). Six FGDs were conducted with IUEs consumers and market-actors, while five case studies were carried out on large scale consumers and market actors with at least 10 years working experience in IUEs merchandizing. Secondary data were sourced from NESREA and Basel Convention Coordinating Centre for Training and Technology Transfer for African Region, Ibadan. Data obtained were content analyzed. Demand for IUEs was hinged on peculiar social relations of consumption and merchandising which rationalized and constructed IUEs as desirable and affordable modern material objects. This relations involved processes of upgrading “solid waste” into tradable commodities infused with deluxe values and potentialities for leveling class. Artful transactions involved offer of disused electronics to market-actors in exchange for upgraded IUEs at a little token. A structure of interdependent actors sustained the IUEs merchandise. It included official gatekeepers such as Customs and NESREA, whose variable roles sustained entry of solid wastes into the market as IUEs; and administrators, merchants and interlinks-security who provided administrative, economic and coercive functions respectively. Furthermore, resuscitators upgrade otherwise wastes into merchandisable goods. Scavengers-collectors extract the irredeemable from merchants, to scrap-collectors who trade them to bulk-scrap-buyers. Bulk-buyers in turn, trade the scraps to domestic iron-smelting companies and/or illegally export them. In essence, IUEs remained tradable even in their end-of-life stages. Thus, local meanings of utility of IUEs and of employment potentialities were constructed against official policy perception of them as solid waste. Through a structured system of market interactions, actor-merchants contrived utility for Imported Used Electronics in the process of merchandise and consumption. Government should therefore accommodate local realities in order to proffer inclusive and robust IUEs policy. 1 results 1
