    Freedom away from parents and guardians for students in higher institutions could have effects on their sexual decisions and behaviours, which when not guided could portend devastating consequences. Such a decision could lead to indulging in transactional sex (TS), a kind of sexual relationship that is adopted in exchange for material and non-material benefits. In this study, we underscored why female students are involved in TS in some Nigerian universities and offer potential remedies that could mitigate or prevent associated negative consequences. The study relied on a qualitative research methodology, adopting in-depth interviews to source data from 40 female students across 5 universities in southeastern Nigeria. Data were analysed in thematic categories that reflected the research questions. Family pressure/parental disconnectedness, gender, peer influence, poor economic background, greed, etc., influenced TS involvement. We also identified some psychosocial and health risks associated with TS. The roles of social service professionals were found to be of much importance, although the universities that were studied barely employed and/or utilised their services

      Aim: To characterize and classify stroke lesions and normal brain tissue in computed tomography (CT) images using statistical texture descriptors. Patients and methods: Two experienced radiologists blinded to each other inspected CT images of 164 stroke patients to identify and categorize stroke lesions into ischaemic and haemorrhagic subtypes. Four regions of interest (ROIs) in each CT slice that demonstrated the lesion; two each representing the lesion and normal tissue were selected. Statistical texture descriptors namely, co-occurrence matrix, run-length matrix, absolute gradient and histogram were calculated for them.  Raw data analysis was performed to identify the parameters that best discriminate between normal brain tissue and stroke lesions. Artificial neural network (ANN) was used to classify the ROIs into normal tissue, ischaemic and haemorrhagic lesions using the radiologists’ identification and categorization as the gold standard, and further analyzed using the receiver operating characteristic curve. Results: Three parameters in each texture class discriminated between normal tissue, ischaemic and haemorrhagic stroke lesions. The discriminating co-occurrence matrix parameters were sum average parameters namely S1-1 SumAverg, S1-0 SumAverg and S0-1 SumAverg.  For the run-length matrix, short run emphasis in horizontal, 1350 and 450 directions were the discriminating features. The discriminating absolute gradient parameters were gradient non-zeros, gradient variance and gradient mean. For the histogram class, the mean, 90th and 99th percentiles were the discriminating parameters. The ANN achieved a sensitivity of 0.637, specificity 0.753, false positive rate (FPR) 0.247, and false negative rate (FNR) 0.363 with co-occurrence matrix. With run-length matrix the sensitivity was 0.544, specificity 0.607, FPR 0.393, and FNR 0.456 while with absolute gradient the sensitivity was 0.546, specificity 0.586, FPR 0.414, FNR 0.454. With histogram, the sensitivity was 0.947, specificity 0.962, FPR 0.038, and FNR 0.053. Conclusion: The histogram texture features showed the highest sensitivity and specificity in the classification of brain tissue and stroke lesions using the artificial neural network.    &nbsp

    This study examined the subjugation and objectification of women in Nigerian films produced in the 21st Century to determine whether the representations of women have changed at the turn of the Century. The objectives of this study were to find out the extent of subjugation of women in Nollywood films in the 21st Century and determine the extent of objectification of women in Nollywood films in the 21st Century. This study was anchored on the feminist muted group theory. The design adopted was a mixed-method approach that combined content analysis and in-depth interviews. The researchers focused on Nollywood films produced from 2000 to 2021 that have women playing leading or supporting roles. A total of 22 films were coded and eleven film experts and scholars were interviewed. It was found that women were not significantly subjugated in Nigerian films produced in the 21st century. However, women are still highly sexually objectified in Nigerian films produced in the 21st century. They are portrayed in a way that viewers can make judgments about them based on their physical appearance and their sex appeal. It was recommended that the Nigerian Film and Video Censors' Board must play its part in reducing the incidence of female objectification in Nigerian films by putting Objectification (O) as a film classification element, in the same breath as Nudity, Strong Language, and Violence (NSL)

    Access to Dry Season Agricultural Content in the Broadcast Media and Dry Season Irrigation Farming among Smallholder Farmers in Nigeria

    Inaccessibility to information could hinder the adoption of dry season agriculture which is very significant to ending the spate of food insecurity in Nigeria. This cross-sectional survey examined access to broadcast media agricultural content and the effect of such information on dry season agriculture practice among smallholder farmers in Nigeria’s Federal Capital Territory (FCT).Participants consisted of 381 smallholder farmers selected from rural settlements in Kuje and Kwali Area councils, through a multi-stage sampling procedure. Data for the study was generated via a self-designed questionnaire. The findings of this study show that access to the broadcast media agricultural content is high (94.2%) in the FCT and the majority (83.1%) of the farmers are particularly exposed to agricultural programmes on dry season farming. However, the regularity of exposure to such programmes is considered rare/occasional by a sizable proportion (44.8%) of the selected farmers. The research further confirms the general acceptability of the broadcast programmes on dry season agriculture but the major snag is that the majority (>50%) of the farmers think that the time at which the information is broadcast is inappropriate. In terms of the practical implications of the programmes, findings also revealed that 50%) remain adamant that dry-season farming is not achievable and productive; therefore, they have not engaged in dry season irrigation agriculture. We concluded that the knowledge gained from the dry season agricultural programmes in the broadcast media is not sufficient for farmers to successfully engage in dry season irrigation farming. The study recommends a long-term and sustained media campaign on dry season farming, the use of interactive programme content, and rescheduling agricultural programmes to farmers’ preferred time could yield the desired impact on dry season irrigation farming and food security in Nigeri

    The study used the innovation system approach to ascertain the intensity and trends of linkages among key actors in the climate change and food security innovation system in Nigeria, Sierra Leone and Liberia. Data were collected through the use of semi structured interview schedule, key informant interviews and focus group discussions (FGDs) and analyzed using percentages, mean scores and trend analysis. Only 1.8% of the farmers from Nigeria, 2.5% from Sierra Leone and 0.7% from Liberia possessed special training on climate change adaptation and food security issues. The presence of local collaboration among actors was higher in Nigeria than in Sierra Leone and Liberia. There was nonexistence of overseas linkages with majority (89.0% for Nigeria; 98.0 for Sierra Leone and 96.8% for Liberia) of the farmers across the three countries. The intensity of linkages / collaborations existing among actors in the enterprise domain, in the three countries, outweighs that with other domains, with higher collaborations existing among the small-scale farmers and famers’ associations. However, there was a perceived increase in the trend of linkage between farmers and R & D institutions in Nigeria between 2007 and 2009, with a linkage index of more than 2. There was also an increasing higher linkage index (of more than 2) between farmers and technology delivery institutions in Nigeria than in Sierra Leone and Liberia, but a low linkage index of less than 2 between farmers and policy making bodies for all the countries. Poor generation of innovations over the past ten years and poor domestic support for climate change adaptation and food security in the West African sub-region were identified. The study points to the need to intensify the collaboration efforts, between local and foreign partners, as this will bring about the generation of better and improved innovations on food security and adaptive measures.

    Lianas are poorly characterized for central African forests. We quantify variation in liana composition, diversity and community structure in different forest types in the Yangambi Man and Biosphere Reserve, Democratic Republic of Congo. These attributes of liana assemblages were examined in 12 1-ha plots, randomly demarcated within regrowth forest, old growth monodominant forest, old growth mixed forest and old growth edge forest. Using a combination of multivariate and univariate community analyses, we visualize the patterns of these liana assemblage attributes and/or test for their significant differences across forest types. The combined 12 1-ha area contains 2,638 lianas (>= 2 cm diameter) representing 105 species, 49 genera and 22 families. Liana species composition differed significantly across forest types. Taxonomic diversity was higher in old growth mixed forests compared to old growth monodominant and regrowth forests. Trait diversity was higher than expected in the regrowth forest as opposed to the rest of forest types. Similarly, the regrowth forest differed from the rest of forest types in the pattern of liana species ecological traits and diameter frequency distribution. The regrowth forest was also less densely populated in lianas and had lower liana total basal area than the rest of forest types. We speculate that the mechanism of liana competitive exclusion by dominant tree species is mainly responsible for the lower liana species diversity in monodominant compared to mixed forests. We attribute variation in liana community structure between regrowth and old growth forests mostly to short development time of size hierarchies
