Semen extenders are liquid diluents that buffer sperm cells and preserve their fertilizing potentials. The commercial carbonated drink (CD) as an extender was evaluated on semen characteristics, fertility and hatchability in Yoruba ecotype chickens (YECs). The fructose of the CD was 1.52?0.05 mg/ml. Under the conditions of 370Celsius, 5% and 10% of CD were added to the egg yolk citrate solution to make 100%. Semen was obtained from ten matured Yoruba ecotype chicken cocks with an average weight of 1.8?0.2 kg. The semen was pooled in a test tube and added to the extenders for preservation at 0, 30 and 60 minutes, respectively, in a factorial design layout. Percentage motility of sperm cells was significantly (p

Borassus aethiopum extract as a biological extender was evaluated on semen quality, fertility and hatchability in chickens under conditions of warm preservation at 37oC. The extenders were prepared in 1:5 and 1:10 ratios (extract to normal saline) and preserved for 0, 1, 2, 3 and 4 hours respectively in a factorial design layout. There was no significant (p>0.05) effect of the extender on semen characteristics within 2 hours of preservation. However, motility (%) was significantly (p0.05) higher in the extender of 1:10 than in the extender of 1:5 and it was above 70%. Using the extender of 1:10 in the fertility and hatchability trial in a completely randomized design layout showed that fertility decreased, 95% in the 0- hour treatment to 73% in the 4-hour treatment while hatchability decreased from 71.4% in the 0-hour treatment to 61.5% in the 4-hour treatment. It may be concluded that the Borassus aethiopum extract could be used to extend and preserve the semen of chickens for 3 hours providing good fertility and hatchability of eggs.

This study investigated the influence of parental history, work-family conflicts and psychological well-being on neglectful parenting practices among middle-class women in selected states in Southwest, Nigeria. A correlational research design was engaged in the study. The sample consisted of 879 middle-class women randomly selected from south-west Nigeria. Childhood Trauma Questionnaire (α=.71), Work-family Conflict Scale (α=.77), Psychological Well-being Scale (α=.89) and The Parenting Style Inventory (α=.82) were employed to generate data for the study. Data collected were analysed using Pearson Product Moment Correlation and Multiple regression model. The results indicated that the three predictor variables jointly accounted for 55% of the total variance in neglectful parenting (F(3,875) = 361.449; R= .744; R2= .553; Adj. R2=.552; P

This study examined the effectiveness of Dialectical Behaviour Therapy (DBT) in reduction of test anxiety among secondary school students with learning disabilities. The study adopted pretest-posttest control group quasi-experimental design with 2x3x2 factorial matrix. Purposive random sampling technique was used to select 42 participants from two private secondary schools in Ogbomosho, Oyo State. The participants were randomly assigned to the experimental and control groups. The instruments used were: Pupils Rating Scale (r=0.83); Stanford Achievement Test: reading comprehension (r=0.79), Mathematics (r=.71) and Westside Test Anxiety Scale (r=0.75). Three hypotheses were tested at 0.05 level of significance. Data were analysed using Analysis of Covariance (ANCOVA). There was main effect of treatment on test anxiety of the participants (F(1,29) = 101.875; P = 0.000 < 0.05)). Participants exposed to DBT (X=25.725) exhibited lesser degree of test anxiety compared with control group (X=36.392) There was, however, no main effect of types of learning disabilities (dyslexia, dyscalculia and dysgraphia) on the test anxiety of the participants. No main effect of gender on test anxiety of the participants was observed. It was recommended that conscious efforts should be made by clinical, counselling, and educational psychologists as well as other stakeholders working with students with learning disabilities to adopt the therapy (DBT) when handling test anxiety among people with cognitive impairment.Keywords: Dialectical behaviour therapy; Learning disabilities, Test anxiety, Dyslexia, Dyscalculia, Dysgraphia

The current study observed the predictive influence of perfectionism and social support on Work-Family Conflict (WFC) among women academics. A correlational method was employed for the study, one hundred and sixty-eight women academics in tertiary institutions in Oyo State were engaged in the study through a purposive random sampling technique. Three major psychological instruments were adopted for data gathering: Work-Family Conflict Scale (a = .87); Multidimensional Scale of Perceived Social Support (a = .78), and Almost Perfect Scale (α= .84). Pearson Product Moment Correlation (PPMC) and multiple regression statistics were used to analyse data. The findings showed that a combination of the independent variables jointly accounted for about 39% of the total variance in WFC (F(4, 167) = 26.183, P < 0.01). Based on the degree of magnitude of each predictor variables in predicting WFC, the study showed that Social Support (β= -.365; t= -5.659, p < 0.01), Discrepancy (β = .268, t = 4.234 p

This study investigated the joint and relative contributions of self-concepts, maternal attachment and religiosity to the prediction of adolescents’ sexual debut. A descriptive survey design through correlational approach was employed. Four hundred and ninety six adolescents from selected secondary schools in Ogbomoso and Oyo areas of Oyo State were randomly selected through a purposive random sampling technique. Four psychological instruments were employed for the study: Self Concept Clarity Scale (α = .83) Inventory of Parents and Peers Attachment (α = .92); Religiosity Measure (α -.84), and Sexual Behaviour Experience Questionnaire (α=.78). Multiple Regression statistics was employed for analysis of the data generated. The outcomes of the study revealed that the three independent variables jointly accounted for about 50% of the total variance in sexual debut. (F(3,495) = 162.95; P < .001). The study further revealed that religiosity (β = -.884; t = -10.828, P < 0.01) is the most potent determinant of sexual debut, followed by maternal attachment (β = -.220; t = -8.461 P < 0.01) and self concept (β = -.225, t – 6.997, P < 0.01) in that order. The outcomes of the study were discussed and it was recommended among others that moral education through religious bodies should be given a chance in Nigerian schools for curtailing some of the undesirable behaviours among youths.
