The variable cowpea productivity across diff erent environments demands evaluating the performance of genotypes in a breeding program prior to their release. The aim of this study was to assess yield stability of eight cowpea advanced breeding lines selected from participatory varietal selection in multilocational trials, and to identify mega-environments for cowpea production in Ghana. The genotypes were evaluated across fi ve environments in 2016 and 2017 in randomized complete block design with three replications. The GEA-R version 4.0 software was used for genotype main eff ect plus genotype by environment interaction (GGE) biplot analyses. Analysis of variance (PROC GLM of SAS using a RANDOM statement with the TEST option) detected signifi cant variations for location, year, genotype, environment, and their interactions. The results showed that the yield performances of the cowpea genotypes were highly infl uenced by genotype × environment interaction eff ects. The principal component 1 (PC1) and PC2 were signifi cant components which accounted for 46.75% and 22.84% of GGE sum of squares, respectively. We showed for the fi rst time, two mega-environments for cowpea production and testing in the major cowpea production agro-ecologies in Ghana. The genotypes SARI-6-2-6 and IT07K-303-1 were adapted to Damongo, Nyankpala, and Tumu, whereas SARI-2-50-80 was adapted to Yendi and Manga. The best ranking location was Damongo followed by Tumu, and Nyankpala. The high-yielding genotypes, IT86D-610, IT10K-837-1, IT07K-303-1, and SARI-2-50-80 had signifi cant higher grain yields than the check (Bawutawuta) and were recommended for release as cultivars (or as breeding lines) to boost cowpea production in Ghana.

Students experiencing academic failure often get the feeling of rejection from their parents, peers, teachers among others which ultimately impacts on their self-esteem. They evaluate themselves based on the subjective opinion from peers which may cause individuals to judge themselves worthy or unworthy based on the feedback they get from others. This study therefore examined the use of emotional intelligence training and cognitive restructuring on self-esteem of secondary school students experiencing academic failure in Ibadan, Oyo State, Nigeria. The moderating effects of gender and academic motivation were also examined. A pretest-posttest, control group, quasi-experimental design with a 3x2x3 factorial matrix was adopted. A multi-stage sampling procedure was employed. Three local government areas were randomly selected from Ibadan, Oyo State, Nigeria. One public Senior Secondary School were randomly selected from each of the local government area. 120 (M= 53, F=67) senior secondary school students 2 who were experiencing academic failure were screened for the self-esteem and were randomly assigned to Emotional Intelligence Training (40), Cognitive Restructuring Therapy (40) and Control Group (40). Treatment lasted for eight weeks training for emotional intelligence training Journal of Humanities Therapy, Humanities Institute, Kangwon National University, Korea 2023, vol.14-1, pp.75~104 https://doi.org/10.33252/jht.2023.6.14.1.75 ISSN 2765-2653(Online) 76 Stephen Oluwaseun Emmanuel ; Moses Oluwafemi Ogundokun_ Effect of Emotional ... Ⅰ. Introduction Students experiencing academic failure often get the feeling of rejection from parents, peers, and teachers, among others; this feedback may reduce their self-esteem. The impact of self-esteem on a variety of outcomes has been the subject of numerous studies in different disciplines of psychology (e.g., Orth, Robins, Widaman, and Conger, 2014; Pyszczynski, Greenberg, Solomon, Arndt, and Schimel, 2004). In the past, researchers considered having a high level of self-esteem as being wholly positive (Baumeister, Heatherton, and Tice, 1993). According to Diener and Diener (1995), having a high self-esteem was linked to a number of favourable outcomes, including life satisfaction and academic performance (Bowles, 1999). Contrarily, low self-esteem was mostly associated with negative outcomes like depression and poor academic performance (Crocker and Park 2004; DeWit, Adlaf, Offord, and Ogborne, 2000). and cognitive restructuring therapy groups. Data were analysed using Analysis of Covariance (ANCOVA) and Multiple Classification Analysis at the 0.05 level of significance. The results indicated that there was a significant main effect of treatments on self-esteem of the participants experiencing academic failure. There was no significant interaction effect of academic motivation and gender on self-esteem of students experiencing academic failures. Both Emotional Intelligence Training and Cognitive Restructuring Therapy were effective in managing self-esteem of students experiencing academic failure. It was recommended that Counselling Psychologists and Educational Psychologists should utilise these therapies to manage self-esteem of students.

Purpose Timely and precise weeding continues to be a major constraint to improved quality and yield of maize in Uganda due to overdependence on manual power. While some farmers have adopted the use of animal draft technology for land preparation, its use for weeding operations remains limited due to limited access to appropriate tools. In this study, a maize weeder that can be attached to an existing ox-plough frame was developed and its field performance evaluated. Methods The weeder consists of the cross beam, shanks, sweeps and frame attachment. The method used involved selecting suitable materials and utilisation of appropriate ergonomic, agronomic and engineering aspects to enable the sizing and construction. It also features the design calculations necessary for the completion of this work. Results The weeding efficiency was found to be 81.9%. The mean effective field capacity of the weeder was 0.10 ha/h with a field efficiency of 83.8%. Conclusion The weeder should meet the maize weeding needs of a small-scale farmer.

The nutrient mining abilities of six Musa genotypes: ‘Agbagba’, ‘PITA 22’, ‘Nsukka Local’, ‘FHIA 17’, ‘Fougamou’, and ‘BITA 7’, grown in organic medium formulated by decomposing rice husks with poultry manure in volume proportions of 3:2, were determined at the Teaching and Research Farm of the Department of Crop Science, University of Nigeria, Nsukka, Nigeria. Results indicated significant variation in nutrient mining with respect to Musa genotype and duration of growth. The medium previously cropped with ‘Agbagba’ recorded highest residual mean values for P and Ca, while the medium cropped with ‘Fougamou’ had the highest residual concentration of Mg and S. Residual amount of K was highest in the medium where ‘PITA 22’ and ‘Nsukka Local’ were previously grown. Peak residual concentration of P and K occurred in the medium in which Musa plants were grown only for 4months, decreasing thereafter, in contrast to Ca, Mg, and S. Residual N tended to increase with longer growth duration of the Musa crops. Follower crop of maize grown in the medium previously cropped with Musa genotypes showed variable performance. While medium previously cropped with ‘PITA 22’ and ‘BITA 7’ favored growth attributes and leaf greenness of the follower maize plant,‘Fougamou’ favored maize fresh weight attributes. Ectomycorrhiza association was observed in medium previously cropped to ‘BITA 7’ and ‘PITA 22’. Generally, ‘Agbagba’ and ‘Fougamou’ seemed to be the most reticent nutrient miners while uptake of P and K appeared to be low 4 months after planting (MAP) in contrast to Ca, Mg, and S uptake. However, substrate previously cropped with ‘PITA 22’, ‘BITA 7’ and ‘Fougamou’ gave rise to superior growth and fresh weight attributes, respectively, of the maize, the follower crop. A prospect of utilizing the ectomycorrhiza association observed with some genotypes to upgrade Musa yields and those of associated or follower crops exist. Key words: follower crop, maize growth, Musa genotypes

Cassava bagasse contains considerable amount of natural single elementary cellulose fibers and white thick root fiber (thick-core fiber) that has seen frequent application in the packaging industry as reinforcement for plastic composite development. However, a review of the literature was unable to find any study that characterized the material properties (such as tensile properties) of both the single elementary and white thick-core cassava cellulose fibers), and their application as potential reinforced filler in tissue engineering scaffold development. In this study, the tensile properties, morphology, crystallinity and thermal degradation profile of non-chemically treated single elementary cellulose fibers and thick-core fibers of different cassava genotypes were investigated. Fibers were tested according to ASTM C1557 under direct tension in a standard mechanical testing system and the cross-sectional area of the fractured regions of the fibers were determined usinga 3D optical microscopy method. Cassava fibers of different genotypes did not show any significant difference in tensile properties, with average tensile strength ranging from (5.1-7.3 MPa), Young’s modulus (258-333 MPa) and failure strain (3.4-4.2 %). Tensile test conducted for several gage lengths did not influence the tensile strength and Young’s modulus of the fibers, however, strain-at-break depended on gage length. Single elementary and thick-core fibers showed similar surface morphology, degree of crystallinity (ranging from 21-40 %) and tensile properties with some variation in elastic modulus. Cassava fibers are thermally stable around 100-200 oC, where processing could be performed. Preliminary results showed an improvement in the mechanical properties of a gelatin scaffold when cassava cellulose microfibers were used as reinforcing fillers. The current findings show that cassava fiber has a reasonable mechanical strength, stiffness and thermal stability, and could be considered as a reinforced biomaterial to improve the mechanical integrity of tissue engineering scaffolds.

The existing gap from strategic innovation in e-government knowledge creation has affected the effort to timely develop e-government policy in Tanzania. This paper is an attempt to describe multiple innovations outside the Tanzania that involve developing country collaboration, institutional innovation and resources and their linkages to national e-government-think tank. The central argument of this paper is to find factors for enhancing the development of national e-government policy innovation outside Tanzania. We developed national e-government policy framework to orchestrate local innovation and forge ahead of the e-government policy innovation. To do so, we developed and administered a set of the questionnaire from government and private institutions, entrepreneurship and social network group. Data collections were conducted from July 15 to September 20, 2015. The exploratory factor analysis using SPSS version 22 was employed to analyze data for strategic innovation, knowledge sharing, and e-government policy innovation. Four critical factors were identified as the key driver to the success of national e-government policy innovation: Coordinate knowledge sharing on e-government policies in the nation and international institutions; empower and coordinate e-government-think tank forum locally and nationally; create a technoculture society at local and national level; and Support e-government research alliance & engagement respectively. In additional, three developing countries were used as a reference model to support these findings. Our conclusion shows how national e-government-think tank and research alliance can become a strategic innovation in e-government towards coordinating knowledge sharing within private and government institutions. This can represent as “valuable and intellectual assets” for government institutions’ stability and change towards national e-government policy innovation process.
