Plot by plot: plotting urbanism as an ordinary process of urbanization

With this paper, we analyse an ordinary urban process, which has received little attention so far and propose a new concept to take account of it: plotting urbanism. It is usually subsumed under terms like “urban informality” or “incremental urbanism” and not studied as a distinct process. In comparing Lagos, Istanbul and Shenzhen we captured four defining features of plotting urbanism: first, it unfolds in a piecemeal fashion with limited comprehensive planning. Second, it emerges from conflicts between multiple overlapping modes of territorial regulation, land tenure and property rights, which result in specific territorial compromises. Third, plotting is based on commodification of housing and land, which might accentuate socio-economic differentiations between property-owners, who often live in the same area, and their tenants. The term “plotting” highlights the key role of the plot in the process. It also alludes to strategic acts of collaboration for individual and collaborative benefit

Entrepreneurial interest and academic performance in Nigeria: evidence from undergraduate students in the University of Ibadan

Abstract Entrepreneurial interest among the youth population is a panacea for unemployment especially due to high turnout of educated individuals in the labour force. This paper provides findings on the factors that determine entrepreneurship interest among the youth population in Nigeria using the University of Ibadan as a case study. Empirical results on whether engagement in entrepreneurial activities interferes with academic performance; extent of involvement and gender differences are also presented. The logit and multinomial logit models were used to examine the factors that influence entrepreneurship interest and interference with academic performance, respectively. Descriptive statistics and the T test were employed in examining the extent of involvement and whether there is a statistically significant difference across gender. The results showed that subjective norm, perceived behavioural control and family business background significantly predicts students’ interest in entrepreneurship. Engagement in entrepreneurial activity has no significant effect on students’ academic performance. Findings suggest relatively low entrepreneurial engagement among students with significant differences across gender

Influence of Human Chorionic Gonadotropin on the Fertility Rate in Artificially Inseminated Rabbit Does

An experiment was carried out on the influence of human chorionic gonadotropin hormone (hCG) on the fertility rate of rabbit does under artificial insemination. The rabbit does (7-8 months old) were used for the trial. The hCG was administered to the rabbit does at varying doses: 0, 50, 100 and 150 I.U representing treatments 1 (control), 2, 3 and 4, respectively. Twenty four does were randomly allotted to the four treatments with six does per treatment in a completely randomised design and the study lasted 5 weeks. The does were inseminated with semen harvested from proven bucks. The results showed that does on 0 and 50 I.U hCG had 0% conception rate, while does on 100 and 150 I.U hCG showed 16.67% conception rate. This implies that hCG at 50 i.u was not enough to initiate ovulation in rabbit does. There were no significant differences (p>0.05) in the weight of doe after parturition, gestation length and litter size among the treatments. Total Litter weight and average litter weight were significant (p<0.05) higher in does administered 150 I.U hCG than those treated with 100 I.U. This study suggested that hCG induced ovulation and influenced the fertility rate of rabbit does when administered with at least 100 I.U to artificially inseminated rabbit does.Keywords: Human chorionic gonadotropin, Conception rate, Rabbit, artificial inseminatio

Iterative evaluation of mobile computer-assisted digital chest x-ray screening for TB improves efficiency, yield, and outcomes in Nigeria.

Wellness on Wheels (WoW) is a model of mobile systematic tuberculosis (TB) screening of high-risk populations combining digital chest radiography with computer-aided automated detection (CAD) and chronic cough screening to identify presumptive TB clients in communities, health facilities, and prisons in Nigeria. The model evolves to address technical, political, and sustainability challenges. Screening methods were iteratively refined to balance TB yield and feasibility across heterogeneous populations. Performance metrics were compared over time. Screening volumes, risk mix, number needed to screen (NNS), number needed to test (NNT), sample loss, TB treatment initiation and outcomes. Efforts to mitigate losses along the diagnostic cascade were tracked. Persons with high CAD4TB score (≥80), who tested negative on a single spot GeneXpert were followed-up to assess TB status at six months. An experimental calibration method achieved a viable CAD threshold for testing. High risk groups and key stakeholders were engaged. Operations evolved in real time to fix problems. Incremental improvements in mean client volumes (128 to 140/day), target group inclusion (92% to 93%), on-site testing (84% to 86%), TB treatment initiation (87% to 91%), and TB treatment success (71% to 85%) were recorded. Attention to those as highest risk boosted efficiency (the NNT declined from 8.2 ± SD8.2 to 7.6 ± SD7.7). Clinical diagnosis was added after follow-up among those with ≥ 80 CAD scores and initially spot -sputum negative found 11 additional TB cases (6.3%) after 121 person-years of follow-up. Iterative adaptation in response to performance metrics foster feasible, acceptable, and efficient TB case-finding in Nigeria. High CAD scores can identify subclinical TB and those at risk of progression to bacteriologically-confirmed TB disease in the near term
