Vocational Skill Mobility and Its Effect on Occupational Engagement Among Tradesmen and Craftsmen in Building Sector

Building sector in Nigeria has suffered skill erosion overtime. Foreigners with special skill has mobilized their skill into the sector and there had been mass exodus of imported skills into the sector thereby forcing citizens to jettison idea of engaging indigenous artisans in the face of superior skills and knowledge. The aim of the study is to appraise the vocational skills and competence of the indigenous and foreign artisans, vocational mobility in building sector, job mobility pattern among artisans, sectors involved, attendant effects, both favorable and unfavorable, and possible ways of addressing identified threat. The study engaged 120 questionnaire using random sampling technique. The questionnaire was designed in Likert scale, structured on sematic rating scale 1 to 5. The study identified the following reasons among others reasons behind the disparity in occupational engagement among artisans in Nigeria building sector, the reasons include: inadequate skill and knowledge by indigenous artisans, no vocational focus, half -baked knowledge of the work, poor workmanship and poor finishing and poor education background or lack of former education among others. The study recommended the following factors as panacea to the problem; reinvigoration of artisans competence, continuous training of the artisans, value reorientation of artisans, promoting technology transfer among indigenous artisans and foreign artisans

Comparison of Near-infrared Spectroscopy with other options for total carotenoids content phenotyping in fresh cassava roots

This study compared the relationship of different phenotyping methods including iCheckTM CAROTENE (iCheck), Chromameter, colour chart and visible/near-infrared spectroscopy (Vis/NIRS) used in quantifying total carotenoids content (TCC) in fresh cassava roots. Using a total of 194 cassava clones harvested from the International Institute of Tropical Agriculture (IITA), Ibadan, we compared the repeatability precision, accuracy of measurement and correlations of these phenotyping methods. From the results, Vis/NIRS-analyzed TCC had high and positive correlations with Chromameter and Color chart (r = 0.91 and 0.71, respectively). On the other hand, the result revealed somewhat moderate correlation (r = 0.67) between Vis/NIRS and iCheck measurements. Vis/NIRS, iCheck and chromameter methods gave high and nearly equal heritability estimates (0.95, 0.98 and 0.98, respectively) illustrating high repeatability precision of these methods; an indication that they can be used for germplasm selection in the early stages of breeding. Conversely, with Bland-Altman plot at 95% confidence level, the accuracy of iCheck was not comparable with that of Vis/ NIRS. The information derived from this analysis directly contributes towards the genetic improvement of root quality traits in cassava and facilitates the sharing of data across cassava breeding consortium

Migration and Agricultural Investment in Southeast, Nigeria

Gender shapes migration and agricultural investments in farming households. Despite indications that gender plays an important role in driving migration and remittance, research in this context is limited. This study therefore, explored rural-urban migration and agricultural investment in Southeast Nigeria. The study adopted a multi-stage sampling technique in the selection of respondents. Cross-sectional data gathered from 200 household heads (100 male-headed households and 100 female-headed households) was used. Using descriptive statistics and ordinary least square regression the findings reveal that majority of male and female migrants (60% and 55% respectively) in male-headed households migrated in search of jobs. Majority of male and female migrants in female-headed households (50% and 55% respectively) migrated in search of jobs. The major determinants of migration were gender of the migrant, gender of the household head, age, income, access to credit, number of migrants in the working age, occupation and number of livelihood activities pursued by the household. The average annual remittance from male migrants in male-headed households was N204,269.3 while that of their female counterparts was N161,297.76. The average annual remittance from male migrants in female-headed households was N189,282.9 while that of their female counterparts was N170,297.8. The average amount of remittance invested in agriculture in male-headed households was N131,334.8 while that of their female counterparts was N151,676.5. The study concludes that gender drives migration, remittances from both the sender and receiver perspectives and household investment decisions. It is however recommended that gender should be mainstreamed in migration policies to consider the peculiarities of both men and women in migration and remittances

Prospects for Genomic Selection in Cassava Breeding

Article purchased; Published online: 28 Sept 2017Cassava (Manihot esculenta Crantz) is a clonally propagated staple food crop in the tropics. Genomic selection (GS) has been implemented at three breeding institutions in Africa to reduce cycle times. Initial studies provided promising estimates of predictive abilities. Here, we expand on previous analyses by assessing the accuracy of seven prediction models for seven traits in three prediction scenarios: cross-validation within populations, cross-population prediction and cross-generation prediction. We also evaluated the impact of increasing the training population (TP) size by phenotyping progenies selected either at random or with a genetic algorithm. Cross-validation results were mostly consistent across programs, with nonadditive models predicting of 10% better on average. Cross-population accuracy was generally low (mean = 0.18) but prediction of cassava mosaic disease increased up to 57% in one Nigerian population when data from another related population were combined. Accuracy across generations was poorer than within-generation accuracy, as expected, but accuracy for dry matter content and mosaic disease severity should be sufficient for rapid-cycling GS. Selection of a prediction model made some difference across generations, but increasing TP size was more important. With a genetic algorithm, selection of one-third of progeny could achieve an accuracy equivalent to phenotyping all progeny. We are in the early stages of GS for this crop but the results are promising for some traits. General guidelines that are emerging are that TPs need to continue to grow but phenotyping can be done on a cleverly selected subset of individuals, reducing the overall phenotyping burden.Bill & Melinda Gates FoundationUKaidCGIAR Research Program on Roots, Tubers and BananasPeer Revie

Manual / Issue 8 / Give and Take

Manual, a journal about art and its making. Give and Take. The eigth issue. Manual 8 (Give and Take) explores interaction, transaction, and social exchange and indebtedness. The earliest known use of the expression “give and take” can be traced to horse racing. It referred to races in which larger, stronger horses carried more weight, and smaller ones, less. Implied therein is an accounting for relative capacities. In such a race, the goal remains the same—crossing the finish line first—but introducing this variable highlights the relationship between the competing horses. A win is only meaningful if each horse can be considered in relation to the others. We . . . find ourselves in a historical moment that makes our interconnectedness both more visible and more complex. Boundaries—physical, geographical, ideological—have become more porous, and the institutions that have provided structure—while always deeply flawed—have shown themselves to be more vulnerable than some of us would have liked to believe. Old systems are breaking down, giving way. New ones will take hold. —Mary-Kim Arnold, from the introduction to Issue 8: Give and Takehttps://digitalcommons.risd.edu/risdmuseum_journals/1034/thumbnail.jp

Adoption of Bio-fortified Pro-Vitamin-A Cassava and Health Outcome of Farming Households in Abia and Anambra States Nigeria

This study examined the relationship between the adoption of bio-fortified pro-vitamin-A cassava varieties and farming households’ health outcomes using cross sectional data obtained from 318 cassava farmers in southeast Nigeria. The data was analysed using binary logistic regression, propensity score matching of treatment effects and percentages. The study found that number of children under five, household size, education of head of household, extension service, ownership of television, radio, mobile phone and tricycle, membership of cooperative societies, and access to credit were the significant predictors of adoption of pro-vitamin-A bio-fortified cassava varieties in the States. The study also found that the main constraints militating against adoption of pro-vitamin-A bio-fortified cassava include decaying of roots immediately after maturation, high cost of cassava stem, and high moisture content. The estimate of the effect of the adoption of bio-fortified pro-vitamin-A cassava varieties on incidence of vitamin-A deficiency related diseases was significant with an average treatment effect on the adopters of -0.463. The adoption of bio-fortified pro-vitamin-A cassava varieties has substantial effect on the reduction of vitamin-A deficiency related health outcomes. There is need for wider awareness and dissemination of the varieties among cassava farmers, while interventions should target the promotion of both production and consumption of such cassava varieties
